Overview

We research, develop and commercialize innovative technologies in two primary areas: molecular technology solutions and sensing solutions. We have a disciplined and integrated business model that is designed to accelerate the process of bringing new and innovative products to market. We identify technologies that can fulfill identified market needs and then take these technologies from the applied research stage through commercialization in our two areas of focus:

Molecular Technology Solutions. We develop molecular technology solutions, which are substances and materials with enhanced performance characteristics obtained by harnessing chemical, physical and biological properties of novel combinations of matter. We focus on substances and materials at the molecular level, including nanomaterials, which are materials whose size can be measured in nanometers, or one billionth of a meter. Examples of our solutions in this area include flame retardants, protective coatings, and materials that can help physicians identify diseased tissues using magnetic resonance imaging, or MRI.

Sensing Solutions. We develop integrated sensing solutions, which are products that combine sensors, software and hardware to measure, monitor and control chemical, physical and biological properties. We have particular expertise in optical, acoustic and wireless technologies. Examples of our solutions in this area include medical monitoring products and industrial instrumentation for aerospace, energy generation and distribution, and defense applications.

We have a successful track record in executing our market-driven business model. Since our inception, we have developed more than a dozen products serving various industries including energy, telecommunications, life sciences and defense. We have created five companies in our areas of focus, sold two of them to industry leaders in their fields, raised private capital for two of our companies, formed one joint venture and entered into four licensing agreements.

Our aggregate revenues from January 1, 2003 through March 31, 2006 were $61.1 million, and our aggregate cost of revenues during that same period were $40.5 million. For the year ended December 31, 2005 and the three months ended March 31, 2006, we had net losses of $2.0 million and $2.1 million, respectively, and we expect to incur significant additional expenses as we expand our business. We also expect significantly greater losses for the foreseeable future primarily due to increased expenditures related to our nanomaterial and medical device product development efforts and due to certain non-cash charges for compensation expense from the grant of stock options.

Our company is organized into three main groups: our Contract Research Group, our Commercialization Strategy Group and our Products Group. These groups work closely together to turn ideas into products.

Prospectus summary

contract research revenues. Our contract research revenues grew from $10.4 million in 2003 to $13.8 million in 2004 and to $15.4 million in 2005. During this same period, our contract research costs increased from $8.9 million in 2003 to $11.0 million in 2004 and to $12.6 million in 2005. In the first quarter of 2006, we generated contract research revenues of $3.9 million while incurring contract research costs of $2.9 million. Our Contract Research Group seeks to continually supply our product pipeline with new opportunities.

Commercialization Strategy Group. Our Commercialization Strategy Group works closely with our network of federal and industrial customers to identify new market opportunities for our technologies. After ideas are driven to proof of concept in the Contract Research Group, our Commercialization Strategy Group develops detailed business plans for commercially viable products. It is at this stage that we first consider investing our own funds to finance the continued development of a product, which is then managed in our Products Group.

Products Group. Our Products Group currently consists of the following three divisions:

Luna Advanced Systems Division. Most new product opportunities that are approved for further development by our management team are initially allocated to our Luna Advanced Systems Division. Products currently managed in this division include medical diagnostic instruments using our innovative ultrasound technologies, non-destructive industrial testing and homeland security devices, remote and secure wireless asset monitoring systems, flame retardants, multi-functional protective coating systems and blast and ballistic resistant materials. We transfer products to existing or new divisions within our Products Group with the resources needed for the successful commercialization of the technology if we determine that a product line is broad enough or that the market opportunity is sufficiently large.

Luna nanoWorks Division. Our Luna nanoWorks Division develops and commercializes innovative products based on nanomaterials made from carbon, or carbon nanomaterials, that have broad potential applications. This division is developing MRI contrast agents, which are materials that can help physicians identify diseased tissues using MRI and that are designed to be potentially safer than, and technically superior to, contrast agents currently on the market. We currently supply nanomaterials to research laboratories and plan to supply proprietary high value-added carbon nanomaterials to customers who manufacture products such as solar cells, strong and light-weight composites and coatings to shield devices from electromagnetic interference.

Luna Technologies Division. Our Luna Technologies Division manufactures and markets test and measurement equipment and integrated sensing solutions. This division’s products are used for process and control monitoring in telecommunications, manufacturing, power generation and distribution, down-hole oil and gas production, aerospace and defense applications. Our products have won numerous awards and are sold and distributed throughout North America, Europe, the Middle East and Asia.

We expect that the capital raised in this offering will provide us greater flexibility in funding the commercialization of new technologies and will provide us the opportunity to increase the speed, quality and volume of products that we can develop.

Our Growth Strategy

We have the following key strategies to achieve our goal of accelerating the development and commercialization of innovative technologies and to create successful products in our areas of focus:

Focus on developing and commercializing a growing portfolio of innovative products. We intend to build and commercialize a growing portfolio of high value-added products using innovative technologies and utilize our existing relationships to identify, prioritize and allocate resources to respond rapidly to market needs, and shorten the time to market for new products.

Transition our mix of revenues to a higher percentage of product sales and license revenues. We plan to commercialize a growing number of products in order to increase the amount of revenues that we generate

Prospectus summary

from product sales and license payments. To this end, we will seek to expand our distribution network and our ability to service our customers. We will also seek to allocate resources to improve our ability to manufacture and shorten the cycle time from idea to market and to monetize our intellectual property portfolio by licensing our technologies. As a result, we believe that product sales and license revenues will comprise a greater portion of our total revenues in the future.

Continue to strengthen our Contract Research Group. We will seek to strengthen our Contract Research Group through increased resource allocation and hiring and by expanding our network of relationships with federal laboratories, major research universities and industry leaders. These steps will provide us the opportunity to grow our applied research business, remain informed of the latest technological advances and increase the quality and volume of high potential technologies that will support our product pipeline.

Expand our intellectual property portfolio in our areas of focus. We will seek to expand our intellectual property portfolio by applying our disciplined processes to generate know-how and intellectual property through our network of relationships and our own research and development efforts. By continuing to expand our intellectual property, we will seek to enhance our competitive position and develop additional products in these areas.

Challenges in Executing our Growth Strategy

We face several challenges to the successful implementation of our growth strategy. In addition, our business is subject to numerous risks, which we highlight in the section entitled “Risk factors” immediately following this prospectus summary. For example, our ability to grow by developing and commercializing multiple products simultaneously requires that we manage a diverse range of projects, expand our personnel resources and broaden our geographic presence. Our inability to do any of these could prevent us from successfully implementing our growth strategy. In addition, the success of our business model depends on our ability to correctly identify market needs for new technologies. If we are not successful in identifying market needs or in developing new products to meet those needs, we may not be successful in growing our product revenues or transitioning our revenues mix from contract research revenues to product sales and license revenues.

We believe that sustained growth at a higher rate will place a strain on our management, as well as on our other human resources. If we are unable to attract and retain qualified personnel as we grow our operations, we may be unable to staff and manage projects adequately, which may slow the development process, result in the commercialization of fewer products or compromise the quality of our work. Moreover, the products that we have developed or are currently developing will compete with other technologically innovative products as well as products incorporating conventional materials and technologies. Our competitors may be able to adapt more quickly to new or emerging technologies and changes in customer requirements. If we are unable to compete successfully against current or new competitors, our product revenues may not increase or may decline.

In addition, our commercial success will depend in part on our obtaining and maintaining intellectual property protection for our technologies as well as successfully enforcing and defending our intellectual property rights against third-party challenges. Moreover, if the commercial versions of our products that are currently under development do not incorporate our proprietary technologies, our intellectual property portfolio may not afford us a competitive advantage.

Risk factors

An investment in our common stock offered by this prospectus involves a substantial risk of loss. You should carefully consider these risk factors, together with all of the other information included in this prospectus, before you decide to purchase shares of our common stock. The occurrence of any of the following risks could harm our business. In that case, the trading price of our common stock could decline, and you may lose part or all of your investment.

Risks Related to Our Business and Technologies

If we are unable to manage our growth effectively, our revenues and profits could be adversely affected.

While historically we have developed and commercialized only a few products at a time, we plan to grow by developing and commercializing multiple products concurrently across many industries, technologies and markets. Our ability to grow by developing and commercializing multiple products simultaneously requires that we manage a diverse range of projects, expand our personnel resources and broaden our geographic presence. Our inability to do any of these could prevent us from successfully implementing our growth strategy, and our revenues and profits could be adversely affected.

As of March 31, 2006, we had 68 research contracts covering a broad range of technologies, industries and markets. To advance the development of multiple promising potential products concurrently, we need to manage effectively the logistics of maintaining the requisite corporate, operational, administrative and financing functions for each of these products. Expanding our operations into new geographic areas and relying on multiple facilities to develop and manufacture different products concurrently pose additional challenges. We have little experience in managing these functions simultaneously for multiple projects in development or in building new infrastructure and integrating the operations of various facilities. If we cannot manage this process successfully, we may be subject to operating difficulties, additional expenditures and reduced revenues.

We need to expand our personnel resources to grow our business effectively. We believe that sustained growth at a higher rate will place a strain on our management, as well as on our other human resources. To manage this growth, we must continue to attract and retain qualified management, professional, scientific and technical and operating personnel. If we are unable to do so, we may be unable to staff and manage projects adequately, which may slow the development process, result in the commercialization of fewer products or compromise the quality of our work.

We have incurred recent losses, and because our strategy for expansion may be costly to implement, we may experience continuing losses which may be significant.

We incurred consolidated net losses of approximately $2.0 million and $2.1 million for the year ended December 31, 2005 and the three months ended March 31, 2006, respectively. We expect to continue to incur significant additional expenses as we expand our business, including increased expenses for research and development, sales and marketing, manufacturing, finance and accounting personnel and expenses associated with being a public company. We may also grow our business in part through acquisitions of additional companies and complementary technologies which could cause us to incur greater than anticipated transaction expenses, amortization or write-offs of intangible assets and other acquisition-related expenses. As a result, we expect that we may likely continue to incur losses for the foreseeable future, and these losses could be substantial.

Because of the numerous risks and uncertainties associated with our business and our expansion strategy, we are unable to predict when or if we will be able to achieve profitability again. If our revenues do not increase, or if our expenses increase at a greater rate than our revenues, we will continue to experience losses. Even if we do achieve profitability, we may not be able to sustain or increase our profitability on a quarterly or annual basis.

We may not be successful in identifying market needs for new technologies and developing new products to meet those needs.

The success of our business model depends on our ability to identify correctly market needs for new technologies. We intend to identify new market needs, but we may not always have success in doing so, in part, because our contract research largely

Risk factors

centers on technologies characterized by constant change and unpredictable markets. Furthermore, we must identify the most promising technologies from a sizable pool of projects. For example, we had 68 contract research projects as of March 31, 2006. If our Commercialization Strategy Group fails to identify the projects with the highest commercial potential or if management does not ensure that only the highest potential projects advance to the commercialization stage, we may not successfully commercialize new products and grow our revenues.

Our growth strategy requires that we not only identify new technologies that meet market needs, but that we also develop successful commercial products that address those needs. We face several challenges in developing successful new products. Many of our existing products and those currently under development—including our Trimetasphere™ carbon nanomaterials, which are nanomaterials in the form of a carbon sphere with three metal atoms enclosed inside—are technologically innovative and require significant and lengthy product development efforts. These efforts include planning, designing, developing and testing at the technological, product and manufacturing-process levels. These activities require us to make significant investments. Although there are many potential applications for our technologies, our resource constraints require us to focus on specific products and to forgo other opportunities. We expect that one or more of the potential products we choose to develop will not be technologically feasible or will not achieve commercial acceptance, and we cannot predict which, if any, of our products we will successfully develop or commercialize. The technologies we research and develop are new and steadily changing and advancing. The products that are derived from these technologies may not be applicable or compatible with the state of technology or demands in existing markets. Our existing products and technologies may become uncompetitive or obsolete if our competitors adapt more quickly than we do to new technologies and changes in customers’ requirements. Furthermore, we may not be able to identify if and when new markets will open for our products given that future applications of any given product may not be readily determinable, and we cannot reasonably estimate the size of any markets that may develop. If we are not able to successfully develop new products, we may be unable to increase our product revenues.

We rely and will continue to rely on contract research for a significant portion of our revenues. Any decrease in these revenues, including Small Business Innovation Research, or SBIR, revenues, could adversely affect our business.

We derive a significant portion of our revenues from contract research that we perform for third parties. Contract research accounted for approximately 61.3%, 93.5% and 86.8% of our consolidated total revenues for the years ended December 31, 2004 and 2005 and the three months ended March 31, 2006, respectively. SBIR revenues accounted for approximately 43.3%, 59.8% and 67.3% of our consolidated total revenues for the years ended December 31, 2004 and 2005 and the three months ended March 31, 2006, respectively, and 40.2% and 52.8% of our pro forma consolidated total revenues, which include the operations of Luna Technologies for the years ended December 31, 2004 and 2005, respectively. Contract research will remain a significant portion of our consolidated total revenues for the foreseeable future. Our strategy for developing innovative technologies and products depends in large part on our ability to continue to enter into and generate revenues from contract research, including SBIR contracts, for which we must comply with certain eligibility criteria. Our contract research customer base includes government agencies, academic institutions and corporations. Our customers are not obligated to extend their agreements with us. In addition, our contracts with government agencies, which accounted for approximately 86.1%, 93.3% and 87.9% of our contract research revenues for the years ended December 31, 2004 and 2005 and the three months ended March 31, 2006, respectively, provide that the U.S. government may terminate funding prior to the expiration of these contracts, regardless of whether we have demonstrated technological feasibility or have met specified milestones. In addition, we may not be successful in securing future contracts. Our customers’ priorities regarding funding for certain projects may change and funding resources may no longer be available at previous levels.

We rely and will continue to rely on contracts and grants awarded under the SBIR program for a significant portion of our revenues. A finding by the Small Business Administration, or SBA, that we no longer qualify to receive SBIR funding could adversely affect our business.

We may not qualify to participate in the Small Business Administration’s, or SBA’s, SBIR program or receive an SBIR award from any federal agency in the future. In order to qualify for SBIR contracts and grants, at least 51% of our equity must be

Risk factors

owned and controlled by U.S. citizens or permanent resident aliens, or by another entity that is at least 51% owned or controlled by U.S. citizens or permanent resident aliens, and we must have 500 or fewer employees. These eligibility criteria are applied as of the time of the award of a contract or grant. In determining whether we satisfy the 51% equity ownership requirement, agreements to merge, stock options, convertible debt and other similar instruments are given “present effect” by the SBA, as though the underlying securities were actually issued unless the exercisability or conversion of such securities is speculative, remote or beyond the control of the security holder. We therefore believe our outstanding options and warrants held by eligible individuals may be counted as, and our convertible debt may be excluded from, outstanding equity for purposes of meeting the 51% equity ownership requirement. As of March 31, 2006, giving present effect to our outstanding options, approximately 76% of our equity was owned by U.S. citizens or permanent resident aliens. Upon the completion of this offering, at least approximately 59% of our equity will be owned by U.S. citizens or permanent resident aliens (and at least approximately 57% assuming exercise of the underwriters’ over-allotment option).

We believe that we are currently in compliance with the SBIR eligibility criteria but we cannot provide assurance that the SBA will interpret its regulations in our favor. We must be able to certify that we meet the SBIR ownership and size requirements as of the time we enter into each SBIR contract or grant, and SBA may review our size status in connection with each SBIR contract or grant. As we grow our business, it is foreseeable that we will eventually exceed the SBIR eligibility limitations and we may need to find other sources to fund our research and development efforts. If we are unsuccessful in obtaining additional contracts or funding grants because we cannot meet the eligibility requirements or if our customers decide to reduce or discontinue support of our products, we may be required to seek alternative sources of revenues or capital.

The SBA could determine that, as a result of Carilion Health System’s equity ownership, the number of our employees exceeds the size limitation placed on SBA contract and SBIR grant recipients, and therefore we will not be eligible to receive future SBA contracts and SBIR grants.

In addition to the U.S. ownership eligibility criteria discussed above, to be eligible for SBA contracts and SBIR grants, the number of our employees including those of any entities that are considered to be affiliated with us, cannot exceed 500. As of March 31, 2006, we, including all of our divisions, had 148 full-time and 13 part-time employees. However, in determining whether we are affiliated with any other entity, the SBA analyzes whether another entity controls or has the power to control us. If the SBA determines that another entity controls or has the power to control us, it will aggregate that entity’s employees (and the employees of its subsidiaries and affiliates) with our own for purposes of applying the 500 employee test.

The SBA may make an affiliation determination based on stock ownership. For example, the SBA may presume that two or more entities have the power to control a company if the entities each own, control or has the power to control, less than 50 percent of the company’s stock, such minority holdings are equal or approximately equal in size, and the aggregate of the minority holdings is large as compared to any other stock holding. However, this presumption may be rebutted by showing that such control or power to control does not in fact exist. Prior to this offering, giving effect to the conversion of our Class A common stock, Class B common stock and Class C common stock into shares of our common stock such that an additional 96,724 shares are issued to Carilion Health System, Carilion Health System held 35.7% of our common stock, and Dr. Kent Murphy owned 42.3% of the voting power of our common stock, and after the offering, these ownership percentages will be approximately equal to 22.9% and 27.1%, respectively. Thus, applying the criteria stated above, the SBA could find that both Carilion Health System and Dr. Murphy own less than 50% of the stock, their percentages are roughly equal, and their respective percentages are large compared to any other stock holding. We believe that the relative beneficial ownership of our individual stockholders rebuts the presumption of control by Carilion Health System because the shares held by our executive officers and directors constitute the controlling interest in us. However, if the SBA were to make a determination that we are affiliated with Carilion Health System, we would exceed the size limitations as Carilion Health System has over 500 employees, and we therefore would lose eligibility for SBA contracts, public contracts, grants and other awards that are set aside for small businesses, including SBIR grants.

Risk factors

We depend on government-funded research contracts for most of our contract research revenues, and a decline in government funding of existing or future government research contracts could adversely affect our revenues and cash flows and our ability to fund our growth.

Government-funded research accounted for approximately 86.1%, 93.3% and 87.9% of our contract research revenues and 52.8%, 87.2% and 76.3% of our consolidated total revenues for the years ended December 31, 2004 and 2005 and the three months ended March 31, 2006, respectively. On a pro forma consolidated basis, which includes the results of operations of Luna Technologies as if acquired on January 1, 2004, government-funded research accounted for 49.0% and 76.9% of our pro forma consolidated total revenues for the years ended December 31, 2004 and 2005, respectively. As a result, we are vulnerable to adverse changes in our revenues and cash flows if a significant number of our government research contracts and subcontracts are simultaneously delayed or canceled for budgetary, performance or other reasons. The U.S. government may cancel these contracts at any time without cause and without penalty or may change its requirements, programs or contract budget, any of which could reduce our revenues and cash flows from U.S. government research contracts. Our revenues and cash flows from U.S. government research contracts could also be reduced by declines or other changes in U.S. defense, homeland security and other federal agency budgets. In addition, we compete as a small business for some of these contracts, and in order to maintain our eligibility to compete as a small business, we (together with any affiliates) must continue to meet size and revenue limitations established by the U.S. government.

In addition to contract cancellations and changes in agency budgets, our future financial results may be adversely affected by curtailment of the U.S. government’s use of contract research providers, including curtailment due to government budget reductions and related fiscal matters. These or other factors could cause U.S. defense and other federal agencies to conduct research internally rather than through commercial research organizations, to reduce their overall contract research requirements or to exercise their rights to terminate contracts. Any of these actions could limit our ability to obtain new contract awards and adversely affect our revenues and cash flows and our ability to fund our growth.

If we cannot successfully transition our revenues mix from contract research revenues to product sales and license revenues, we may not be able to fully execute our business model or grow our business.

Our business model and future growth depend on our ability to transition to a revenues mix that contains significantly larger product sales and license revenues components. Product sales and license revenues potentially offer greater scalability than services-based contract research revenues. Our current plan is to increase our portfolio of commercial products and, accordingly, we expect that our future product sales and license revenues will represent a larger percentage of total revenues. However, if we are unable to develop and grow our product sales and license revenues to augment our contract research revenues, our ability to execute our business model or grow our business could suffer.

We face and will face substantial competition in several different markets that may adversely affect our results of operations.

We face or will face substantial competition from a variety of companies in several different markets. Our competitors in contract research include, but are not limited to, companies such as General Dynamics Corporation, Lockheed Martin Corporation, SAIC, Inc. and SRA International, Inc. In the molecular technology solutions products market, our competitors include, but are not limited to, large public manufacturers such as The Dow Chemical Company, E.I. du Pont de Nemours and Company, Rohm and Haas Company and 3M Company, as well as emerging companies. In addition, in the MRI contrast agent market our competitors include Amersham Plc, Berlex Laboratories, Inc., Bracco Diagnostics, Inc., and Mallinckrodt Inc. In the sensor solutions products market, our competitors include, but are not limited to, large companies such as Agilent Technologies, Inc., Analog Devices, Inc., Freescale Semiconductor, Inc., JDS Uniphase Corp., Robert Bosch GmbH and Silicon Sensing, as well as emerging companies.

The products that we have developed or are currently developing will compete with other technologically innovative products as well as products incorporating conventional materials and technologies. We expect that our products will compete with

Risk factors

companies in a wide range of industries, including semiconductors, electronics, biotechnology, textiles, alternative energy, military, defense, healthcare, telecommunications, industrial measurement, security applications and consumer electronics.

Many of our competitors have longer operating histories, greater name recognition, larger customer bases and significantly greater financial, sales and marketing, manufacturing, distribution, technical and other resources than we do. These competitors may be able to adapt more quickly to new or emerging technologies and changes in customer requirements. In addition, current and potential competitors have established or may establish financial or strategic relationships among themselves or with existing or potential customers or other third parties. Accordingly, new competitors or alliances among competitors could emerge and rapidly acquire significant market share. We cannot assure you that we will be able to compete successfully against current or new competitors, in which case our net revenues may fail to increase or may decline.

A substantial portion of our technology is subject to retained rights of our licensors, and we may not be able to prevent the loss of those rights or the grant of similar rights to third parties.

A substantial portion of our technology is licensed from academic institutions, corporations and government agencies. Under these licensing arrangements, a licensor may obtain rights over the technology, including the right to require us to grant a license to one or more third parties selected by the licensor or that we provide licensed technology or material to third parties for non-commercial research. For example, under the Trimetasphere™ nanomaterials license, we have been required to supply Trimetasphere™ nanomaterials to three foreign and five domestic university research institutions and one corporate industrial research laboratory and may be required to supply such materials to other organizations for non-commercial research. The grant of a license for any of our core technologies to a third party could have a material and adverse effect on our business. In addition, our licensors retained certain rights under the licenses including the right to grant additional licenses to a substantial portion of our core technology to third parties for noncommercial academic and research use. It is difficult to monitor and enforce such noncommercial academic and research uses, and we cannot predict whether the third party licensees would comply with the use restrictions of such licenses. We could incur substantial expenses to enforce our rights against them. We also may not fully control the ability to assert or defend those patents or other intellectual property which we have licensed from other entities, or which we have licensed to other entities.

In addition, some of our licenses with academic institutions give us the right to use certain technology previously developed by researchers at these institutions. In certain cases we also have the right to practice improvements on the licensed technology to the extent they are encompassed by the licensed patents and within our field of use. Our licensors may currently own and may in the future obtain additional patents and patent applications that are necessary for the development, manufacture and commercial sale of our anticipated products. We may be unable to agree with one or more academic institutions from which we have obtained licenses that certain intellectual property developed by researchers at these academic institutions is covered by our existing licenses. In the event that the new intellectual property is not covered by our existing licenses, we would be required to negotiate a new license agreement. We may not be able to reach agreement with current or future licensors on commercially reasonable terms, if at all, or the terms may not permit us to sell our products at a profit after payment of royalties, which could harm our business.

Some of our patents may cover inventions that were conceived or first reduced to practice under, or in connection with, U.S. government contracts or other federal funding agreements. With respect to inventions conceived or first reduced to practice under a federal funding agreement, the U.S. government may retain a nonexclusive, non-transferable, irrevocable, paid-up license to practice or have practiced for or on behalf of the United States the invention throughout the world. We may not have succeeded in our efforts to retain title in patents, maintain ownership of intellectual property or in limiting the U.S. government’s rights in our proprietary technologies and intellectual property whether such intellectual property was developed in the performance of a federal funding agreement or developed at private expense.

Risk factors

Our proprietary rights may not adequately protect our technologies.

Our commercial success will depend in part on our obtaining and maintaining patent, trade secret, copyright and trademark protection of our technologies in the United States and other jurisdictions as well as successfully enforcing this intellectual property and defending this intellectual property against third-party challenges. We will only be able to protect our technologies from unauthorized use by third parties to the extent that valid and enforceable intellectual property protections, such as patents or trade secrets, cover them. In particular, we place considerable emphasis on obtaining patent and trade secret protection for significant new technologies, products and processes. Furthermore, the degree of future protection of our proprietary rights is uncertain because legal means afford only limited protection and may not adequately protect our rights or permit us to gain or keep our competitive advantage. Moreover, the degree of future protection of our proprietary rights is uncertain for products that are currently in the early stages of development—such as the Trimetasphere™ carbon nanomaterials products—because we cannot predict which of these products will ultimately reach the commercial market or whether the commercial versions of these products will incorporate proprietary technologies.

Our patent position is highly uncertain and involves complex legal and factual questions. Accordingly, we cannot predict the breadth of claims that may be allowed or enforced in our patents or in third-party patents. For example:

we or our licensors might not have been the first to make the inventions covered by each of our pending patent applications and issued patents;

we or our licensors might not have been the first to file patent applications for these inventions;

others may independently develop similar or alternative technologies or duplicate any of our technologies;

it is possible that none of our pending patent applications or the pending patent applications of our licensors will result in issued patents;

our issued patents and issued patents of our licensors may not provide a basis for commercially viable technologies, or may not provide us with any competitive advantages, or may be challenged and invalidated by third parties; and

we may not develop additional proprietary technologies that are patentable.

Patents may not be issued for any pending or future pending patent applications owned by or licensed to us, and claims allowed under any issued patent or future issued patent owned or licensed by us may not be valid or sufficiently broad to protect our technologies. Moreover, protection of certain of our intellectual property may be unavailable or limited in the United States or in foreign countries, and certain of our products—including our Trimetasphere™ carbon nanomaterials products—do not have foreign patent protection. Any issued patents owned by or licensed to us now or in the future may be challenged, invalidated, or circumvented, and the rights under such patents may not provide us with competitive advantages. In addition, competitors may design around our technology or develop competing technologies. Intellectual property rights may also be unavailable or limited in some foreign countries, and in the case of certain products no foreign patents were filed or can be filed. This could make it easier for competitors to capture or increase their market share with respect to related technologies. Although we are not currently involved in any legal proceedings related to intellectual property, we could incur substantial costs to bring suits in which we may assert our patent rights against others or defend ourselves in suits brought against us. An unfavorable outcome of any such litigation could have a material adverse effect on our business and results of operations.

We also rely on trade secrets to protect our technology, especially where we believe patent protection is not appropriate or obtainable. However, trade secrets are difficult to protect. We vigorously pursue confidentiality agreements and contractual provisions with our collaborators, employees, and consultants to protect our trade secrets and proprietary know-how. These agreements may be breached and or may not have adequate remedies for such breach. While we use reasonable efforts to protect our trade secrets, our employees, consultants, contractors or scientific and other advisors, or those of our strategic partners, may unintentionally or willfully disclose our information to competitors. If we were to enforce a claim that a third party

Risk factors

had illegally obtained and was using our trade secrets, our enforcement efforts would be expensive and time consuming, and the outcome would be unpredictable. In addition, courts outside the United States are sometimes unwilling to protect trade secrets. Moreover, if our competitors independently develop equivalent knowledge, methods and know-how, it will be more difficult for us to enforce our rights and our business could be harmed.

If we are not able to defend the patent or trade secret protection position of our technologies, then we will not be able to exclude competitors from developing or marketing competing technologies, and we may not generate enough revenues from product sales to justify the cost of development of our technologies and to achieve or maintain profitability.

We also rely on trademarks to establish a market identity for Luna and Luna products. We currently have one registered trademark in the United States and three pending trademark applications filed with the U.S. Patent and Trademark Office. To maintain the value of our trademarks, we might have to file lawsuits against third parties to prevent them from using trademarks confusingly similar to or dilutive of our registered or unregistered trademarks. Also, we might not obtain registrations for our pending trademark applications, and might have to defend our registered trademark and pending trademark applications from challenge by third parties. Enforcing or defending our registered and unregistered trademarks might result in significant litigation costs and damages, including the inability to continue using certain trademarks.

Third parties may claim that we infringe their intellectual property, and we could suffer significant litigation or licensing expense as a result.

Various U.S. and foreign issued patents and pending patent applications, which are owned by third parties, exist in our technology areas. Such third parties may claim that we infringe their patents. Because patent applications can take several years to result in a patent issuance, there may be currently pending applications, unknown to us, which may later result in issued patents that our technologies may infringe. For example, we are aware of competitors with patents in technology areas applicable to our optical test equipment products. Such competitors may allege that we infringe these patents. There could also be existing patents of which we are not aware that our technologies may inadvertently infringe. If third parties assert claims against us alleging that we infringe their patents or other intellectual property rights—including third parties that have asserted claims against businesses that we have acquired prior to our acquisition of these businesses—we could incur substantial costs and diversion of management resources in defending these claims, and the defense of these claims could have a material adverse effect on our business, financial condition, and results of operations. In addition, if third parties assert claims against us and we are unsuccessful in defending against these claims, these third parties may be awarded substantial damages, as well as injunctive or other equitable relief against us, which could effectively block our ability to make, use, sell, distribute, or market our products and services in the United States or abroad. For example, we acquired a business that had received a letter in 2002 from a competitor alleging infringement of certain patents. The competitor sent an additional letter on January 14, 2004 to the business that we acquired, again alleging infringement of the competitor’s patents. Neither we nor the business that we acquired have received any further communications from this third party. We cannot currently predict whether this third party, or any other third party, will assert a claim against us, or whether any third parties that have asserted such claims against businesses that we have acquired will assert claims or pursue infringement litigation against us; nor can we predict the ultimate outcome of any such potential claims or litigation.

Commercial application of nanotechnologies, or technologies involving nanomaterials, is new and the scope and breadth of patent protection is uncertain. Consequently, the patent positions of companies involved in nanotechnologies have not been tested and complex legal and factual questions for which important legal principles will be developed or may remain unresolved. In addition, it is not clear whether such patents will be subject to interpretations or legal doctrines that differ from conventional patent law principles. Changes in either the patent laws or in interpretations of patent laws in the United States and other countries may diminish the value of our nanotechnology-related intellectual property. Accordingly, we cannot predict the breadth of claims that may be allowed or enforced in our nanotechnology-related patents or in third party patents.

In the event that a claim relating to intellectual property is asserted against us, or third parties not affiliated with us hold pending or issued patents that relate to our products or technology, we may seek licenses to such intellectual property or

Risk factors

challenge those patents. However, we may be unable to obtain these licenses on commercially reasonable terms, if at all, and our challenge of the patents may be unsuccessful. Our failure to obtain the necessary licenses or other rights could prevent the sale, manufacture, or distribution of our products and, therefore, could have a material adverse effect on our business, financial condition, and results of operations.

For example, we are a party to an exclusive license agreement with NASA for certain patented ultrasound technology. The field of this license is limited to measurement of intracranial pressure and compartment syndrome. We currently engage in ultrasound product development activities in bone strength measurement, embolus detection and detection of concealed weapons. To the extent that these activities are covered by the licensed NASA patents, we may be required to acquire an additional license from NASA. We cannot currently predict whether NASA would grant an additional license to us for these fields of use, if such a license were required.

As a provider of contract research to the U.S. government, we are subject to federal rules, regulations, audits and investigations, the violation or failure of which could adversely affect our business.

We must comply with and are affected by laws and regulations relating to the award, administration and performance of U.S. government contracts. Government contract laws and regulations affect how we do business with our government customers and, in some instances, impose added costs on our business. A violation of specific laws and regulations could result in the imposition of fines and penalties or the termination of our contracts or debarment from bidding on contracts. In some instances, these laws and regulations impose terms or rights that are more favorable to the government than those typically available to commercial parties in negotiated transactions. For example, the U.S. government may terminate any of our government contracts and, in general, subcontracts, at their convenience, as well as for default based on performance.

In addition, U.S. government agencies, including the Defense Contract Audit Agency and the Department of Labor, routinely audit and investigate government contractors. These agencies review a contractor’s performance under its contracts, cost structure and compliance with applicable laws, regulations and standards. The U.S. government also may review the adequacy of, and a contractor’s compliance with, its internal control systems and policies, including the contractor’s purchasing, property, estimating, compensation and management information systems. Any costs found to be improperly allocated to a specific contract will not be reimbursed, while such costs already reimbursed must be refunded. If an audit uncovers improper or illegal activities, we may be subject to civil and criminal penalties and administrative sanctions, including termination of contracts, forfeiture of profits, suspension of payments, fines and suspension or prohibition from doing business with the U.S. government. In addition, we could suffer serious reputational harm if allegations of impropriety were made against us.

In March 2003, the Office of Inspector General of the Department of Commerce advised us that the government was investigating anonymous allegations of contract improprieties. We have cooperated fully and extensively with that investigation through interviews and document production. In April 2003, the government advised our regulatory counsel that to date no wrongdoing had been identified, although the government indicated that we may not have fully complied with contractual reporting requirements in one or two instances, which the government did not specify. We believe that the investigation has been resolved favorably, based on statements by the government investigator to our employees in June 2003, and that this matter effectively is at an end absent any advice or communication from the government to the contrary. However, there can be no assurance as to how or whether our relationships, business, financial condition or results of operations will ultimately be affected, if at all, by the investigation.

On November 9, 2004, we received a subpoena from the Department of Defense Office of the Inspector General covering certain government research contracts awarded to us between January 1, 1998 and November 9, 2004 to determine if we had duplicated work in our submission of project reports to the government. In connection with the investigation, the government alleged that duplication occurred in three research reports that we prepared under the contracts. We submitted a response to the Inspector General in September 2005 challenging the government’s findings. On November 15, 2005, we entered into a

Risk factors

settlement agreement with the government and received a general release with respect to the civil and administrative claims in this matter in return for a payment of $165,333.

In March 2006, our senior management became aware that seven foreign national citizens who were working for us had access to International Traffic in Arms Regulations, or ITAR, controlled technical data. Such data may be deemed to have been exported/disclosed to certain of these individuals without the required export licenses. We do not believe that exports of ITAR-controlled technical data occurred to any other unauthorized parties. In addition, we do not believe that any disclosures to foreign nationals involved technology related to classified contracts. Following this discovery, in an effort to ensure full compliance with ITAR we submitted voluntary disclosure of these circumstances to the U.S. Department of State in April 2006. While the Department of State encourages such voluntary disclosure, we nevertheless could be subject to potential investigation and may be exposed to potential regulatory consequences ranging from a no-action letter, government oversight of facilities and export transactions, monetary penalties, and in extreme cases, debarment from government contracting, denial of export privileges and criminal sanctions.

In addition to the risk of government audits and investigations, U.S. government contracts and grants impose requirements on contractors and grantees relating to ethics and business practices, which carry civil and criminal penalties ranging from monetary fines, assessments, loss of the ability to do business with the U.S. government and certain other criminal penalties.

We may also be prohibited from commercially selling certain products that we develop under our Contract Research Group or related products based on the same core technologies if the U.S. government determines that the commercial availability of those products could pose a risk to national security. For example, certain of our wireless technologies have been classified as secret by the U.S. government and as a result we cannot sell them commercially. Any of these determinations would limit our ability to generate product sales and license revenues.

We are subject to significant foreign and domestic government regulations, including environmental and health and safety regulations, and failure to comply with these regulations could harm our business.

Our facilities and current and proposed activities involve the use of a broad range of materials that are considered hazardous under applicable laws and regulations. Accordingly, we are subject to a number of foreign, federal, state, and local laws and regulations relating to health and safety, protection of the environment, and the storage, use, disposal of, and exposure to, hazardous materials and wastes. We could incur costs, fines and civil and criminal penalties, personal injury and third party property damage claims, or could be required to incur substantial investigation or remediation costs if we were to violate or become liable under environmental, health and safety laws. Moreover, a failure to comply with environmental laws could result in fines and the revocation of environmental permits, which could prevent us from conducting our business. Liability under environmental laws can be joint and several and without regard to fault. There can be no assurance that violations of environmental health and safety laws will not occur in the future as a result of the inability to obtain permits, human error, equipment failure or other causes. Environmental laws could become more stringent over time, imposing greater compliance costs and increasing risks and penalties associated with violations, which could harm our business. Accordingly, violations of present and future environmental laws could restrict our ability to expand facilities, pursue certain technologies, and could require us to acquire costly equipment, or to incur potentially significant costs to comply with environmental regulations.

Risk factors

Directive currently exempts monitoring instruments from its requirements. If the European Commission were to remove this exemption in the future, we would be required to change our manufacturing processes and redesign products regulated under the RoHS Directive in order to be able to continue to offer them for sale within the European Union. For some products, substituting certain components containing regulated hazardous substances may be difficult, costly or result in production delays. We will continue to review the applicability and impact of both directives on the sale of our products within the European Union, and although we cannot currently estimate the extent of such impact, they are likely to result in additional costs and could require us to redesign or change how we manufacture our products, any of which could adversely affect our operating results. Failure to comply with the directives could result in the imposition of fines and penalties, inability to sell covered products in the European Union and loss of revenues.

Compliance with foreign, federal, state and local environmental laws and regulations represents a small part of our present budget. If we fail to comply with any such laws or regulations, however, a government entity may levy a fine on us or require us to take costly measures to ensure compliance. Any such fine or expenditure may adversely affect our development. We are committed to complying with and, to our knowledge, are in compliance with, all governmental regulations. We cannot predict the extent to which future legislation and regulation could cause us to incur additional operating expenses, capital expenditures, or restrictions and delays in the development of our products and properties.

Our ability to develop and market certain of our current and potential products may be hindered as a result of FDA regulatory requirements and a lengthy and expensive approval process.

Certain of our current and potential products will require regulatory clearances or approvals prior to commercialization. In particular, our Trimetasphere™ nanomaterial-based MRI contrast agent and our ultrasound diagnostic devices for measuring certain medical conditions will be considered a drug and medical devices, respectively, under the Federal Food, Drug & Cosmetic Act, or FDC Act. Drugs and medical devices are subject to rigorous preclinical testing and other approval requirements by the Food and Drug Administration, or FDA, pursuant to the FDC Act, and regulations under the FDC Act, as well as by similar health authorities in foreign countries. Various federal statutes and regulations also govern or influence the testing, manufacturing, safety, labeling, packaging, advertising, storage, registration, listing and recordkeeping related to marketing of these products. The process of obtaining these clearances or approvals and the subsequent compliance with appropriate federal statutes and regulations require the expenditure of substantial resources. We cannot be certain that any required FDA or other regulatory approval will be granted or, if granted, will not be withdrawn. Our failure to obtain the necessary regulatory approvals, or our failure to obtain them in a timely manner, will prevent or delay our commercialization of new products and our business could suffer.

Our failure to attract, train and retain skilled employees would adversely affect our business and operating results.

The availability of highly trained and skilled technical and professional personnel is critical to our future growth and profitability. Competition for scientists, engineers, technicians and professional personnel is intense and competitors aggressively recruit key employees. Although we have not previously experienced material difficulties in hiring or retaining these personnel, our growth strategy and future needs for additional experienced personnel, particularly in highly specialized areas such as nanomaterial manufacturing and innovative ultrasound technologies, may make it more difficult to meet all of our needs for these employees in a timely manner. Although we intend to continue to devote significant resources to recruit, train and retain qualified employees, we may not be able to attract and retain these employees, especially in technical fields where the supply of experienced qualified candidates is limited. Any failure to do so would have an adverse effect on our business.

In addition, our future success depends in a large part upon the continued service of key members of our senior management team. In particular, our Chairman, CEO and founder, Kent A. Murphy, Ph.D., is essential to our overall management as well as the development of our technologies, our culture and our strategic direction. All of our executive officers and key employees are at-will employees, and, except with respect to Kent A. Murphy, Ph.D., we do not maintain any key-person life insurance policies. The loss of any of our management or key personnel could seriously harm our business.

Risk factors

We might require additional capital to support business growth, and this capital might not be available.

We intend to continue to make investments to support our business growth and may require additional funds to respond to business challenges, including the need to develop new products or enhance our existing products, enhance our operating infrastructure, complete our development activities, build our commercial scale manufacturing facilities and acquire complementary businesses and technologies. Accordingly, we may need to engage in equity or debt financings to secure additional funds for these investments. If we raise additional funds through issuances of equity or convertible debt securities, our existing stockholders could suffer significant dilution, and any new equity securities we issue could have rights, preferences and privileges superior to those of holders of our common stock, including shares of common stock sold in this offering. Furthermore, such financings may jeopardize our ability to apply for SBIR grants or qualify for SBIR contracts or grants, and our dependence on SBIR grants may restrict our ability to raise additional outside capital. Our ability to obtain additional capital could be restricted by the covenants in our existing senior secured credit facility with First National Bank. Among other things, these covenants restrict us, without the prior approval of First National Bank, from guaranteeing the debt of an affiliate or subsidiary or incurring in excess of $200 thousand non-First National Bank debt annually. Any debt financing obtained by us in the future could involve restrictive covenants relating to our capital raising activities and other financial and operational matters, which may make it more difficult for us to obtain additional capital and to pursue business opportunities, including potential acquisitions. In addition, we may not be able to obtain continued SBIR funding, or other additional financing on terms favorable to us, if at all. In order to retain SBIR eligibility, we may be restricted in our ability to raise certain forms of equity capital from institutional investors. For example, in connection with the closing of our financing with Carilion Health System on December 30, 2005, we were not able to raise all proceeds through the issuance of equity without potentially jeopardizing our SBIR eligibility. We therefore elected to issue debt in the amount of $5.0 million of the total $8.0 million raised in such financing to maintain SBIR eligibility. Under the terms of these notes, we agreed that we will not draw down any amount under our existing senior secured credit facility with First National Bank or incur additional indebtedness other than under certain limited conditions. If we are unable to obtain adequate financing or financing on terms satisfactory to us, when we require it, our ability to continue to support our business growth and to respond to business challenges could be significantly limited.

We expect to incur significant expenditures in connection with a grant from the City of Danville, Virginia. If we fail to make certain agreed upon expenditures, we may be obligated to repay part or all of the proceeds from such grant.

In March 2004, we received a grant of $900 thousand from the City of Danville, Virginia under a Grant Agreement to support the expansion of economic and commercial growth within the City. Under the Grant Agreement, we agreed to locate a nanomaterials manufacturing and research facility and maintain its operations in Danville until March 25, 2009. Our obligations under this Grant Agreement require us to incur significant expenditures in order to retain such proceeds from the grant. Specifically, we agreed under the Grant Agreement to invest at least $5.2 million in capital equipment expenditures and $1.2 million in certain facilities by September 25, 2006 and to maintain such investments in our Danville facility until March 25, 2009. We also agreed to create by September 25, 2006 at least 54 new full-time jobs at the Danville facility at an average annual wage of at least $39 thousand plus benefits, and to maintain these jobs at such facility until March 25, 2009. These contractual requirements will restrict the use of significant assets and could obligate us to an annual payroll obligation exceeding $2.0 million until March 25, 2009. To the extent such hiring results in salaries in excess of the required minimum wages, our annual payroll obligation could be substantially greater than $2.0 million. If we fail to make these capital expenditures and create these jobs by September 25, 2006, we will be obligated to repay the City of Danville all or a portion of the $900 thousand in funds based on a formula of the pro rata shortfall of such expenditures and jobs falling below such required levels. At this time, we do not anticipate that we will satisfy the investment and hiring targets of the grant prior to September 25, 2006, and we expect that we may have to return some or all of the grant proceeds. We currently have classified the full amount of the grant as a liability on our balance sheet in anticipation of returning the funds.

Risk factors

We have limited experience manufacturing our products in commercial quantities in a cost-effective manner, which could adversely impact our business.

We have produced most of our products on a custom order basis rather than pursuant to large contracts that require production on a large volume basis. Accordingly, other than the commercial manufacture of products by our Luna Technologies Division, we have no experience manufacturing products in large volume. Because our experience in large scale manufacturing is limited, we may encounter unforeseen difficulties in our efforts to manufacture other products or materials in commercial quantities. For example, we may need to develop or in-license Trimetasphere™ nanomaterial purification and isolation technology, which would result in manufacturing delays or shortfalls. We may also encounter difficulties and delays in manufacturing our products for the following reasons:

we plan to expand our manufacturing operations, and our production processes may have to change to accommodate this growth;

to increase our manufacturing output significantly, we will have to attract and retain qualified employees, who are in short supply, for the assembly and testing operations;

we might have to sub-contract to outside manufacturers which might limit our control of costs and processes; and

our manufacturing operations may have to comply with government specifications including FDA regulations.

If we are unable to keep up with demand for our products, our revenues could be impaired, market acceptance for our products could be adversely affected and our customers might instead purchase our competitors’ products. Moreover, failure to develop and maintain a U.S. market for goods developed with U.S. government-licensed technology may result in the cancellation of the relevant U.S. government licenses. Our inability to manufacture our products successfully would have a material adverse effect on our revenues.

Even if we are able to manufacture our products on a commercial scale, the cost of manufacturing our products may be higher than we expect. If the costs associated with manufacturing are not significantly less than the prices at which we can sell our products, we may not be able to operate at a profit.

We depend on third-party vendors for specialized components in our manufacturing operations, making us vulnerable to supply shortages and price fluctuations that could harm our business.

We primarily rely on third-party vendors for the manufacture of the specialized components used in our products. Although we do not have any sole source suppliers of materials, the highly specialized nature of our supply requirements poses risks that we may not be able to locate additional sources of the specialized components required in our business. For example, we are aware of only two manufacturers that produce the special lasers used in our optical test equipment. Moreover, none of these third-party vendors is obligated to continue to supply us with components. Our reliance on these vendors subjects us to a number of risks that could impact our ability to manufacture our products and harm our business, including interruption of supply.

Any significant delay or interruption in the supply of components, or our inability to obtain substitute components or materials from alternate sources at acceptable prices in a timely manner, could impair our ability to meet the demand of our customers and harm our business.

Our nanotechnology-enabled products are new and may be, or may be perceived as being, harmful to human health or the environment.

While we believe that none of our current products contain chemicals known by us to be hazardous or subject to environmental regulation, it is possible our current or future products, particularly carbon-based nanomaterials, may become

Risk factors

subject to environmental regulation. We intend to develop and sell carbon-based nanomaterials as well as nanotechnology-enabled products, which are products that include nanomaterials as a component to enhance those products’ performance. Nanomaterials and nanotechnology-enabled products have a limited historical safety record. Because of their size or shape or because they may contain harmful elements, such as gadolinium and other rare-earth metals, our products could pose a safety risk to human health or the environment. These characteristics may also cause countries to adopt regulations in the future prohibiting or limiting the manufacture, distribution or use of nanomaterials or nanotechnology-enabled products. Such regulations may inhibit our ability to sell some end user products containing those materials and thereby harm our business or impair our ability to develop commercially viable products.

The subject of nanotechnology has received negative publicity and has aroused public debate. Government authorities could, for social or other purposes, prohibit or regulate the use of nanotechnology. Ethical and other concerns about nanotechnology could adversely affect acceptance of our potential products or lead to government regulation of nanotechnology-enabled products.

We face risks associated with our international business.

Our Luna Technologies Division and our Luna nanoWorks Division currently conduct business internationally and we might considerably expand our international activities in the future. Our international business operations are subject to a variety of risks associated with conducting business internationally, including:

changes in or interpretations of foreign regulations that may adversely affect our ability to sell our products, perform services or repatriate profits to the United States;

the imposition of tariffs;

hyperinflation or economic or political instability in foreign countries;

imposition of limitations on or increase of withholding and other taxes on remittances and other payments by foreign subsidiaries or joint ventures;

conducting business in places where business practices and customs are unfamiliar and unknown;

the imposition of restrictive trade policies;

the imposition of inconsistent laws or regulations;

the imposition or increase of investment and other restrictions or requirements by foreign governments;

uncertainties relating to foreign laws and legal proceedings;

having to comply with a variety of U.S. laws, including the Foreign Corrupt Practices Act;

having to comply with U.S. export control regulations and policies that restrict our ability to communicate with non-U.S. employees and supply foreign affiliates and customers; and

having to comply with licensing requirements.

We do not know the impact that these regulatory, geopolitical and other factors may have on our international business in the future.

Risks Related to This Offering

Our common stock has never been publicly traded, and we expect that the price of our common stock will fluctuate substantially.

Before this initial public offering, there has been no public market for our common stock. An active public trading market may not develop after completion of this offering or, if developed, may not be sustained. The initial public offering price may not be

Risk factors

indicative of prices that will prevail in the trading market. The public trading price for our common stock after this offering will be affected by a number of factors, including:

changes in earnings estimates, investors’ perceptions, recommendations by securities analysts or our failure to achieve analysts’ earning estimates;

changes in our status as an entity eligible to receive SBIR contracts and grants;

quarterly variations in our or our competitors’ results of operations;

general market conditions and other factors unrelated to our operating performance or the operating performance of our competitors;

announcements by us, or our competitors, of acquisitions, new products, significant contracts, commercial relationships or capital commitments;

commencement of, or involvement in, litigation;

any major change in our board of directors or management;

changes in governmental regulations or in the status of our regulatory approvals;

announcements related to patents issued to us or our competitors and to litigation;

a lack of, limited or negative industry or security analyst coverage; and

developments in our industry.

In addition, the stock prices of many technology companies have experienced wide fluctuations that have often been unrelated to the operating performance of those companies. These factors may materially and adversely affect the market price of our common stock.

New investors in our common stock will experience immediate and substantial dilution.

Our initial public offering price is substantially higher than the book value per share of our common stock. If you purchase common stock in this offering, you will incur immediate dilution of $3.91 in net tangible book value per share of common stock. This amount represents the difference between the assumed initial public offering price of $7.00 per share, which is based on the mid-point of the range on the front cover of this prospectus, and the net tangible book value per share of common stock after the offering of $3.09. In addition, the number of shares available for issuance under our stock plans may increase annually without further stockholder approval. Investors will incur additional dilution upon the exercise of stock options and warrants. See “Dilution.”

If there are substantial sales of our common stock, our stock price could decline.

If our existing stockholders sell a large number of shares of our common stock or the public market perceives that these sales may occur, the market price of our common stock could decline. Upon the closing of this offering, assuming no outstanding options are exercised prior to the closing of this offering, we will have approximately 9,734,325 shares of common stock outstanding. The 3,500,000 shares to be sold under this prospectus will be freely tradable without restriction or further registration under the federal securities laws, unless purchased by our affiliates. Taking into consideration the effect of the 180-day lock-up agreements that have been entered into by certain of our stockholders, we estimate that the remaining 6,234,325 shares of our common stock outstanding upon the closing of this offering will be available for sale pursuant to Rule 144, Rule 144(k) and Rule 701, as follows:

566 shares will be immediately eligible for sale in the public market without restriction pursuant to Rule 144(k);

no additional shares will be eligible for sale in the public market under Rule 144 or Rule 701 beginning 90 days after the date of this prospectus, subject to volume, manner of sale, and other limitations under those rules;

Risk factors

3,998,777 additional shares will become eligible for sale, subject to the provisions of Rule 144, Rule 144(k) or Rule 701, beginning 180 days after the date of this prospectus, upon the expiration of agreements not to sell such shares entered into between the underwriters and such stockholders; and

2,234,982 additional shares will be eligible for sale from time to time thereafter upon expiration of their respective one-year holding periods, but could be sold earlier if the holders exercise any available registration rights. Of such shares subject to the provisions of Rule 144, 1,492,032 and 639,442 shares may be sold by Carilion Health System beginning August 4, 2006 and December 30, 2006, respectively, and 103,508 shares may be sold by three individuals beginning November 22, 2006.

Existing stockholders holding an aggregate of 5,489,872 shares of common stock (including shares of our common stock purchasable pursuant to warrants to purchase our common stock), based on shares outstanding as of March 31, 2006, have rights with respect to the registration of these shares of common stock with the SEC. See “Description of capital stock—Registration Rights.” If we register these shares of common stock, these holders will be able to sell immediately those shares in the public market.

Within three months following the completion of this offering, we intend to file a registration statement to register 12,715,000 shares of common stock reserved for issuance under our 2003 Stock Plan and 2006 Equity Incentive Plan, thus permitting the resale of such shares. As of March 31, 2006, 4,812,367 shares were subject to outstanding options, 1,505,850 of which options were vested.

Once we register these shares, they can be freely sold in the public market upon issuance, subject to the underwriter lock-up agreements, our stock purchase restriction agreements and restrictions on our affiliates.

In addition, holders of warrants exercisable for up to 61,214 shares of common stock may exercise those rights and subsequently sell the underlying shares in the public market.

ThinkEquity Partners LLC, on behalf of the underwriters, may in its sole discretion, at any time without notice, release all or any portion of the shares subject to the lock-up agreements, which would result in more shares being available for sale in the public market at earlier dates. Sales of common stock by existing stockholders in the public market, the availability of these shares for sale, our issuance of securities or the perception that any of these events might occur could materially and adversely affect the market price of our common stock.

In addition, employees holding options exercisable for 1,830,028 shares of our common stock have entered into an agreement not to sell more than 20.0% of such shares in any year during the five years following the effective date of this offering, provided, any share subject to such annual limit not sold in a year may be sold in subsequent years notwithstanding such limitation. Certain members of our management holding options exercisable for 2,220,054 shares of our common stock have entered into an agreement not to sell more than 15.0% of such shares in any year during the five years following the effective date of this offering, provided, any share subject to such annual limit not sold in a year may be sold in subsequent years notwithstanding such limitation. We have the right to waive any of these resale restrictions for employees and management at our discretion, and in such instance, the shares would become freely tradable.

Our management will have broad discretion over the use of the proceeds to us from this offering and might not apply the proceeds of this offering in ways that increase the value of your investment.

Our management will have broad discretion to use the net proceeds from this offering, and you will be relying on the judgment of our management regarding the application of these proceeds. They might not apply the net proceeds of this offering in ways that increase the value of your investment. We expect to use the net proceeds from this offering for general corporate purposes, which may include working capital, capital expenditures, other corporate expenses and potential acquisitions of complementary products, technologies or businesses. We have not allocated these net proceeds for any specific purposes. Our management might not be able to yield a significant return, if any, on any investment of these net proceeds.

Risk factors

Our directors and management will collectively control over 54% of our outstanding common stock.

Immediately after this offering, our directors and executive officers and their affiliates will collectively control approximately 54.4% of our outstanding common stock or approximately 51.2% if the underwriters exercise their over-allotment option in full. As a result, these stockholders, if they act together, will be able to influence our management and affairs and all matters requiring stockholder approval, including the election of directors and approval of significant corporate transactions. You and other stockholders will have minimal influence over these actions. This concentration of ownership may have the effect of delaying or preventing a change in control of our company and might adversely affect the market price of our common stock.

Our financial results may vary significantly from period to period which may reduce our stock price.

Our financial results may fluctuate as a result of a number of factors, many of which are outside of our control, which may cause the market price of our common stock to fall. For these reasons, comparing our operating results on a period-to-period basis may not be meaningful, and you should not rely on our past results as an indication of our future performance. Our financial results may be negatively affected by any of the risk factors listed in this “Risk factors” section and, in particular, the following risks:

a reduction of contract research funding;

decisions by government agencies, academic institutions or corporations not to exercise contract options or to modify, curtail or terminate our major contracts;

failure to estimate or control contract costs;

adverse judgments or settlements in legal disputes;

expenses related to acquisitions, mergers or joint ventures; and

other one-time financial charges.

We will incur increased costs as a result of being a public company.

As a public company, we will incur significant legal, accounting and other expenses that we did not incur as a private company. We will incur costs associated with our public company reporting requirements. We also anticipate that we will incur costs associated with corporate governance requirements, including requirements under the Sarbanes-Oxley Act of 2002, as well as new rules implemented by the SEC and the National Association of Securities Dealers, Inc., or NASD. We expect these rules and regulations to increase our legal and financial compliance costs and to make some activities more time-consuming and costly. We also expect these rules and regulations may make it more difficult and more expensive for us to obtain director and officer liability insurance and we may be required to accept reduced policy limits and coverage or incur substantially higher costs to obtain the same or similar coverage. As a result, it may be more difficult for us to attract and retain qualified individuals to serve on our board of directors or as executive officers. We cannot predict or estimate the amount of additional costs we may incur or the timing of such costs.

Investors could lose confidence in our financial reports, and our stock price may be adversely affected, if our internal control over financial reporting are found not to be effective by management or by an independent registered public accounting firm or if we make disclosure of existing or potential significant deficiencies or material weaknesses in those controls.

Beginning with our Annual Report for the year ending December 31, 2007, Section 404 of the Sarbanes-Oxley Act of 2002 requires us to include an internal control report with our Annual Report on Form 10-K. That report must include management’s assessment of the effectiveness of our internal control over financial reporting as of the end of the fiscal year. Additionally, our independent registered public accounting firm will be required to issue a report on management’s assessment of our internal control over financial reporting and a report on their evaluation of the operating effectiveness of our internal control over financial reporting.

Risk factors

We continue to evaluate our existing internal control over financial reporting against the standards adopted by the Public Company Accounting Oversight Board, or PCAOB. During the course of our ongoing evaluation of the internal controls, we may identify areas requiring improvement, and may have to design enhanced processes and controls to address issues identified through this review. Remedying any deficiencies, significant deficiencies or material weaknesses that we or our independent registered public accounting firm may identify, may require us to incur significant costs and expend significant time and management resources. We cannot assure you that any of the measures we implement to remedy any such deficiencies will effectively mitigate or remedy such deficiencies. Investors could lose confidence in our financial reports, and our stock price may be adversely affected, if our internal controls over financial reporting are found not to be effective by management or by an independent registered public accounting firm or if we make disclosure of existing or potential significant deficiencies or material weaknesses in those controls.

Our independent auditors have identified material weaknesses and significant deficiencies in our internal controls, and if we are unable to develop, implement and maintain appropriate controls we will not be able to comply with applicable regulatory requirements imposed on reporting companies.

In connection with the audit of our financial statements for each of the three years in the period ended December 31, 2005, our independent registered public accounting firm identified certain weaknesses in our internal control over financial reporting, which they considered to be material weaknesses and significant deficiencies. Specifically, because we lack appropriate resources and personnel with sufficient experience, our independent registered public accounting firm noted weaknesses in our ability to account for certain complex accounting transactions relating to business combinations and consolidation matters, to account for share-based payments to employees and consultants, as well as weaknesses in our ability to prepare timely consolidated financial statements in accordance with U.S. generally accepted accounting principles and Regulation S-X under the Securities Exchange Act of 1934, as amended. We also lack adequate cutoff and accrual procedures which materially affected recognition of expenses and, in certain instances, related revenues. These weaknesses led to significant audit adjustments for each of the three years in the period ended December 31, 2005 which had a material effect on our financial statements.

Our business operations were relatively small for several years and, as a result, we have operated with very limited staffing of key accounting functions. Such limited staffing made it difficult for us to segregate certain accounting functions. Because of these circumstances, we have relied on outside consultants to supplement our internal accounting staff and to meet our financial reporting obligations.

We are actively recruiting key senior accounting and finance employees to include a new Chief Financial Officer and other accounting staff to enhance our internal control and procedures over financial reporting. Upon hiring a new Chief Financial Officer, our current Chief Financial Officer will continue to serve as our Executive Vice President, Corporate Development. We have recently hired a Chief Accounting Officer as well as an additional senior accountant. These individuals have prior experience handling external financial reporting in a public company environment and should improve our ability to prepare timely consolidated financial statements as well to address more complex accounting matters, such as business combinations and share-based payments. We also hired an additional accounts payable and payroll accountant to improve segregation of duties and redistribute the overall workload on our accounting staff.

We also intend to establish new and enhanced systems of internal control that we believe will be necessary to allow management to report on, and our independent auditors to attest to, our internal controls. To improve the timeliness of our financial reporting, we have instituted a new detailed closing schedule to enhance overall completeness and quality of our reporting. The new schedule was first implemented in March 2006 and provides guidance on routine processes, such as procedures for handling key account reconciliations, month end cutoff procedures for accounts payable and accrued expenses as well as cutoff procedures for revenue and related receivables. The documentation will be expanded in later periods to provide detailed guidance of our entire closing process including preparation of interim and year-end consolidated financial statements and related notes. We have also taken measures to improve our cutoff and accrual procedures.

Risk factors

Specifically, we have implemented a process to improve our estimation of subcontractor expenses to ensure completeness of our direct costs and related revenue. We will continue to review this process to monitor the sufficiency of such policies and procedures.

Although we do not believe we have material weaknesses or significant deficiencies related to our policies and procedures that pertain to maintenance of records, authorizations of receipts and expenditures, or prevention or timely detection of unauthorized acquisition, use, or disposition of our assets, we have not performed specific tests to determine the effectiveness of key controls within these policies and procedures. We intend to monitor those policies and procedures in connection with the establishment of a formally documented system of internal control. We are beginning a comprehensive documentation of our internal controls processes in order to identify additional areas for improvement as well as in anticipation of our future requirements under the Sarbanes-Oxley Act of 2002. We have assigned personnel to begin the process with the expectation of completing documentation of certain key processes by the end of the second quarter of 2006.

While we anticipate being able to implement fully the requirements relating to internal controls and all other applicable requirements of the Sarbanes-Oxley Act of 2002 in a timely fashion, we cannot be certain as to the timing of the completion of our evaluation and testing and any necessary remediation or the impact of the same on our operations. Our development, implementation and maintenance of appropriate internal controls will depend materially both on our successful hiring and retention of key senior accounting personnel. If we are not able to complete the assessment required under Section 404 in a timely manner, we and our independent registered public accounting firm would be unable to conclude that our internal control over financial reporting is effective as of December 31, 2007.

If we are unable to attract and retain qualified personnel, to implement and integrate financial reporting and accounting systems or if we are unable to scale these systems to our growth, we may not have adequate, accurate or timely financial information, and we may be unable to meet our reporting obligations or comply with the requirements of the SEC, the Nasdaq National Market or the Sarbanes-Oxley Act of 2002, which could result in the imposition of sanctions, including the suspension or delisting of our common stock from the Nasdaq National Market and the inability of registered broker dealers to make a market in our common stock, or investigation by regulatory authorities. Any such action or other negative results caused by our inability to meet our reporting requirements or comply with legal and regulatory requirements or by disclosure of an accounting, reporting or control issue could adversely affect the price of our class common stock. Further and continued determinations that there are significant deficiencies or material weaknesses in the effectiveness of our internal control over financial reporting could also reduce our ability to obtain financing or could increase the cost of any financing we obtain and require additional expenditures to comply with applicable requirements.

Anti-takeover provisions in our amended and restated certificate of incorporation and bylaws and Delaware law could discourage a takeover.

Our amended and restated certificate of incorporation and bylaws and Delaware law contain provisions that might enable our management to resist a takeover. These provisions include:

a classified board of directors;

advance notice requirements to stockholders for matters to be brought at stockholder meetings;

a supermajority stockholder vote requirement for amending certain provisions of our amended and restated certificate of incorporation and bylaws; and

the right to issue preferred stock without stockholder approval, which could be used to dilute the stock ownership of a potential hostile acquirer.

These provisions might discourage, delay or prevent a change in control of our company or a change in our management. The existence of these provisions could adversely affect the voting power of holders of common stock and limit the price that investors might be willing to pay in the future for shares of our common stock. See “Description of capital stock.”

Risk factors

Changes in, or interpretations of, accounting rules and regulations, such as expensing of stock options, could result in unfavorable accounting charges or require us to change our compensation policies.

Accounting methods and policies, including policies governing revenues recognition, expenses, and accounting for stock options are subject to further review, interpretation and guidance from relevant accounting authorities, including the SEC. Changes to, or interpretations of, accounting methods or policies in the future may require us to reclassify, restate or otherwise change or revise our financial statements, including those contained in this prospectus. Prior to January 1, 2006, we were not required to record stock-based compensation charges if the employee’s stock option exercise price equals or exceeds the fair market value of our common stock at the date of grant.

On December 16, 2004, the FASB issued SFAS No. 123 (revised 2004), Share-Based Payment, which is a revision of SFAS No. 123, Accounting for Stock-Based Compensation (SFAS No. 123R). SFAS No. 123R supersedes APB Opinion No. 25, Accounting for Stock Issued to Employees, and amends SFAS No. 95, Statement of Cash Flows. Generally, the approach in SFAS No. 123R is similar to the approach described in SFAS No. 123. However, SFAS No. 123R requires all share-based payments to employees, including grants of employee stock options, to be recognized in the income statement based on their fair values. Pro forma disclosure is no longer an alternative. We are required to adopt SFAS No. 123R on January 1, 2006, and have adopted it as of that date.

As permitted by SFAS No. 123, we accounted for share-based payments to employees through December 31, 2005 using APB Opinion No. 25’s intrinsic value method and, as such, generally recognized no compensation cost for employee stock options. Accordingly, the adoption of SFAS No. 123R’s fair value method will have a significant impact on the presentation of our results of operations, although it will have no impact on our overall financial position. The impact of adoption of SFAS No. 123R cannot be predicted at this time because it will depend on levels of share-based payments granted in the future and the assumptions for the variables which impact the computation.

We rely heavily on stock options to motivate existing employees and to attract new employees. When we are required to expense stock options, we may then choose to reduce our reliance on stock options as a motivation tool. If we reduce our use of stock options, it may be more difficult for us to attract and retain qualified employees. If we do not reduce our reliance on stock options, our reported earnings will decrease.

Information regarding forward-looking statements

This prospectus, including the sections entitled “Summary,” “Risk factors,” “Management’s discussion and analysis of financial condition and results of operations” and “Business” may contain forward-looking statements. These statements may relate to, but are not limited to, expectations of future operating results or financial performance, capital expenditures, introduction of new products, regulatory compliance, plans for growth and future operations, as well as assumptions relating to the foregoing. Forward-looking statements are inherently subject to risks and uncertainties, some of which cannot be predicted or quantified. These risks and other factors include, but are not limited to, those listed under “Risk factors.” In some cases, you can identify forward-looking statements by terminology such as “may,” “will,” “should,” “could,” “expect,” “plan,” “anticipate,” “believe,” “estimate,” “predict,” “intend,” “potential,” “continue,” “seek” or the negative of these terms or other comparable terminology. These statements are only predictions. Actual events and/or results may differ materially.

We believe that it is important to communicate our future expectations to our investors. However, there may be events in the future that we are not able to accurately predict or control and that may cause our actual results to differ materially from the expectations we describe in our forward-looking statements. Except as required by applicable law, including the securities laws of the United States and the rules and regulations of the SEC, we do not plan to publicly update or revise any forward-looking statements after we distribute this prospectus, whether as a result of any new information, future events or otherwise. Potential investors should not place undue reliance on our forward-looking statements. Before you invest in our common stock, you should be aware that the occurrence of any of the events described in the “Risk factors” section and elsewhere in this prospectus could harm our business, prospects, operating results and financial condition. Although we believe that the expectations reflected in the forward-looking statements are reasonable, we cannot guarantee future results, levels of activity, performance or achievements. The forward-looking statements contained in this prospectus are excluded from the safe harbor protection provided by the Private Securities Litigation Reform Act of 1995 and Section 27A of the Securities Act of 1933, as amended.

Use of proceeds

We estimate that the net proceeds from the sale of the 3,500,000 shares of our common stock that we are selling in this offering will be approximately $21.3 million, based on an assumed initial public offering price of $7.00 per share, the mid-point of the range on the front cover of this prospectus, after deducting the underwriting discount and estimated offering expenses. A $1.00 increase (decrease) in the assumed initial public offering price of $7.00 per share would increase (decrease) our net proceeds from this offering by approximately $3.3 million, assuming that the number of shares offered by us, as set forth on the cover page of this prospectus, remains the same and after deducting estimated underwriting discounts and commissions. If the underwriters’ over-allotment option is exercised in full, we estimate that we will receive additional net proceeds of approximately $3.9 million.

We intend to use the net proceeds from this offering principally to fund further development and expansion of our products and product candidates, in particular our nanomaterial and ultrasound-related product candidates, and for general working capital purposes. Specifically, in 2006 and 2007 we currently estimate spending:

approximately $4 million to $6 million to develop disease-targeting MRI contrast agents and other nanomaterial applications through completion of pre-clinical trials and the filing of an Investigational New Drug application for a lead contrast agent;

approximately $2 million to $3 million to complete FDA Phase I clinical trials for one lead disease-targeting MRI contrast agent including generation of preliminary efficacy data;

approximately $2 million to $3 million to complete technological development of our first medical device product based on our innovative ultrasound platform technology which is necessary to commence the regulatory review and approval process; and

an additional $2 million to $3 million to fund studies necessary to commence and complete the 510(k) premarketing notification review process with the FDA to allow us to market in the U.S. our first medical device product based on our innovative ultrasound platform technology.

Thereafter, we intend to use the net proceeds of this offering to continue to fund FDA clinical trials of additional, currently unidentified, MRI contrast agent and ultrasound medical device products, with the remainder being available for general working capital purposes. However, due to the uncertainties inherent in the clinical trial process and given that our product candidates have not yet entered clinical development, we are unable to estimate the total costs that will be required to complete the development of our product candidates. As a result, we cannot estimate what amount of the net proceeds will be available for general working capital purposes.

Moreover, our current estimates may change as we begin to develop and expand our product candidates, and we may decide to use our net proceeds for other product candidates or other business purposes. In addition, we may decide to fund our development efforts in part or in whole through outside sources, including licensing revenues or other sources of financing. The foregoing use of proceeds are only our current estimates, and we retain broad discretion to change the application of the proceeds from this offering.

We have not made specific plans with respect to the remaining proceeds of this offering and, therefore, cannot specify all uses for the net proceeds. Accordingly, our management will have broad discretion over the use of the net proceeds in this offering. The amounts and timing of our actual expenditures will depend upon numerous factors, including the status of our development and commercialization efforts and the amount of proceeds actually raised in this offering.

Additional purposes of this offering are to establish a public market for our common stock and to facilitate our future access to public markets, if, for example, additional funds are required to complete FDA clinical trials. We may also use a portion of the net proceeds for the acquisition of, or investment in, companies, technologies, products or assets that complement our business. We have no present understandings, commitments or agreements to enter into any acquisitions or investments. Pending these uses, we intend to invest the net proceeds of this offering in short-term, investment-grade interest-bearing securities or guaranteed obligations of the United States government.

Dividend policy

We have never declared or paid any dividends on our capital stock. We anticipate that we will retain any earnings to support operations and to finance the growth and development of our business. Therefore, we do not expect to pay cash dividends in the foreseeable future. Any future determination relating to our dividend policy will be made at the discretion of our board of directors and will depend on a number of factors, including earnings, capital requirements, financial condition, prospects and other factors that our board of directors may deem relevant.

Capitalization

The following table sets forth our cash and cash equivalents and capitalization as of March 31, 2006:

on an actual basis;

on an as adjusted basis to give effect to the sale by us of 3,500,000 shares of common stock at an assumed initial public offering price of $7.00 per share, the mid-point of the range on the front cover of this prospectus, less the underwriting discount and estimated offering expenses.

(1)

Certain stockholders that have received shares of our common stock in connection with our acquisition of Luna Technologies have the right to redeem a percentage of the outstanding shares issued pursuant to that transaction. This redemption right is extinguished upon the effectiveness of this offering.

A $1.00 increase (decrease) in the assumed initial public offering price of $7.00 per share would increase (decrease) each of cash and cash equivalents, additional paid-in capital, total stockholders’ equity and redeemable common stock, and total capitalization by approximately $3.3 million, assuming that the number of shares offered by us, as set forth on the cover page of this prospectus, remains the same and after deducting estimated underwriting discounts and commissions. The as adjusted information discussed above is illustrative only and following the completion of this offering will be adjusted based on the actual initial public offering price and other terms of this offering determined at pricing.

Capitalization

The table above is based on 6,137,601 shares outstanding as of March 31, 2006 and an additional 96,724 shares of common stock to be issued to Carilion Health System in connection with certain anti-dilution provisions afforded to such stockholder upon the effectiveness of this offering, and it excludes:

4,812,367 shares of common stock issuable upon exercise of options outstanding at a weighted-average exercise price of $0.90 per share, which includes 2,834,129 shares of common stock issuable upon exercise of options outstanding at an exercise price of $0.35 per share, 113,047 shares of common stock issuable upon exercise of options outstanding at an exercise price of $0.39 per share, and 1,865,191 shares of common stock issuable upon exercise of options outstanding at an exercise price of $1.77 share;

235,777 shares of common stock reserved for future issuance upon the exercise of options available for grant under our 2003 Stock Plan;

69,390 shares of common stock issued or reserved for issuance in connection with the acquisition of Luna Technologies that were held in escrow on that date, and 146 shares of common stock issuable upon the exercise of warrants at an exercise price of $37.26 per share held in escrow as of that date, and which shares and warrants to purchase shares are expected to be cancelled upon the closing of this offering.

We adopted our 2006 Equity Incentive Plan in February 2006, subject to stockholder approval, which will be effective upon the completion of this offering.

The table should be read in conjunction with “Management’s discussion and analysis of financial condition and results of operations” and our consolidated financial statements and related notes included elsewhere in this prospectus.

Dilution

If you invest in our common stock, your interest will be diluted immediately to the extent of the difference between the assumed initial public offering price of $7.00 per share of our common stock, the mid-point of the range on the front cover of this prospectus, and the as adjusted net tangible book value per share of our common stock after this offering. Net tangible book value as of March 31, 2006 was $8.7 million, or $1.40 per share. Our net tangible book value per share set forth below represents our total tangible assets (total assets less intangible assets) less total liabilities, divided by the number of shares of our common stock outstanding on March 31, 2006, which includes shares of common stock that will be issued to Carilion Health System in connection with certain antidilution provisions afforded to that stockholder upon the effectiveness of this offering.

Dilution per share to new investors represents the difference between the amount per share paid by new investors who purchase shares of common stock in this offering and the as adjusted net tangible book value per share of common stock immediately after the completion of this offering. Giving effect to the sale of shares of our common stock offered by us at the assumed initial public offering price of $7.00 per share, the mid-point of the range on the front cover of this prospectus, and after deducting the underwriting discount and estimated offering expenses, our as adjusted net tangible book value as of March 31, 2006 would have been approximately $30.0 million. This amount represents an immediate increase in net tangible book value of $1.69 per share to our existing stockholders and an immediate dilution in net tangible book value of $3.91 per share to new investors purchasing shares of our common stock in this offering. The following table illustrates this dilution:



Assumed initial public offering price per share		$7.00
Net tangible book value per share as of March 31, 2006	$1.40
Increase in net tangible book value per share attributable to this offering per share to existing investors	$1.69
As adjusted net tangible book value per share after this offering		$3.09

Dilution per share to new investors		$3.91

A $1.00 increase (decrease) in the assumed initial public offering price of $7.00 per share would increase (decrease) our net tangible book value by approximately $3.3 million, our as adjusted net tangible book value per share after this offering by approximately $0.33 and dilution per share to new investors by approximately $0.67, assuming that the number of shares offered by us, as set forth on the cover page of this prospectus, remains the same and after deducting estimated underwriting discounts and commissions.

The following table sets forth, on an as adjusted basis, as of March 31, 2006, the differences between the number of shares of common stock purchased from us, the total consideration paid, and the average price per share paid by existing stockholders and new investors purchasing shares of our common stock in this offering, before deducting the underwriting discount and estimated offering expenses at an assumed initial public offering price of $7.00 per share, the mid-point of the range on the front cover of this prospectus.


	Shares Purchased			Total Consideration			Average Price Per Share
	Number	Percent		Amount	Percent		Average Price Per Share
Existing stockholders	6,234,325	64.0	%	$11,463,456	31.9	%	$1.84
New investors	3,500,000	36.0		24,500,000	68.1		7.00

Total	9,734,325	100.0	%	$35,963,456	100.0	%

Dilution

The table above excludes, as of March 31, 2006:

4,812,367 shares of common stock issuable upon exercise of options outstanding at a weighted-average exercise price of $0.90 per share, which includes 2,834,129 shares of common stock issuable upon exercise of options outstanding at an exercise price of $0.35 per share, 113,047 shares of common stock issuable upon exercise of options outstanding at an exercise price of $0.39 per share, and 1,865,191 shares of common stock issuable upon exercise of options outstanding at an exercise price of $1.77 per share;

235,777 shares of common stock reserved for future issuance upon the exercise of options available for grant under our 2003 Stock Plan;

69,390 shares of common stock issued or reserved for issuance in connection with the acquisition of Luna Technologies that were held in escrow on that date, and 146 shares of common stock issuable upon the exercise of warrants at an exercise price of $37.26 per share held in escrow as of that date, which shares and warrants are expected to be cancelled in connection with the closing of this offering.

Assuming the conversion in full of the senior convertible promissory notes as well as exercise in full of all options and warrants outstanding or reserved for future issuance as of April 27, 2006 (other than shares and warrants held in escrow), the number of shares purchased by existing stockholders would be increased by 6,686,651 shares to 12,920,976 shares, total consideration paid by them would be increased by approximately $4,532,441 to $15,995,897 and the average price per share paid by them would be decreased by $0.60 per share to $1.24 per share.

We adopted our 2006 Equity Incentive Plan in February 2006, subject to stockholder approval which will be effective upon the completion of this offering.

If the underwriters exercise their over-allotment option in full, the percentage of shares of common stock held by existing stockholders will decrease to approximately 60.3% of the total number of shares of our common stock outstanding after this offering, and the number of shares held by new investors will be increased to 4,100,000, or approximately 39.7% of the total number of shares of our common stock outstanding after this offering.

Within three months following the completion of this offering, we intend to file a registration statement under the Securities Act to register the issuance of 12,715,000 shares of common stock reserved for issuance under the 2003 Stock Plan and the 2006 Equity Incentive Plan.

Management’s discussion and analysis of financial condition and results of operations

The following discussion and analysis of our financial condition and results of operations should be read in conjunction with our consolidated financial statements and the related notes to those statements included elsewhere in this prospectus. In addition to historical financial information, the following discussion and analysis contains forward-looking statements that involve risks, uncertainties and assumptions. Our actual results and timing of selected events may differ materially from those anticipated in these forward-looking statements as a result of many factors, including those discussed under “Risk factors” and elsewhere in this prospectus.

Overview

We research, develop and commercialize innovative technologies in two primary areas: molecular technology solutions and sensing solutions. We have a disciplined and integrated business model that is designed to accelerate the process of bringing new and innovative products to market. We identify technologies that can fulfill large and unmet market needs and then take these technologies from the applied research stage through commercialization in our two areas of focus:

Our aggregate revenues from January 1, 2003 through March 31, 2006 were $61.1 million, and our aggregate cost of revenues during that same period were $40.5 million. However, we had net losses of $2.0 million and $2.1 million for the year ended December 31, 2005 and the three months ended March 31, 2006, respectively, and we expect to incur significant additional expenses as we expand our business. We also expect significantly greater losses for the foreseeable future primarily due to increased expenditures related to our nanomaterial and medical device product development efforts.

Management’s discussion and analysis of financial condition and results of operations

Our annual revenues were $17.6 million in 2003, $22.6 million in 2004, and $16.5 million in 2005, and $4.5 million during the three months ended March 31, 2006. We generate revenues through contract research, product sales and license fees. Historically, our contract research revenues have accounted for a large and growing proportion of our total revenues, and we expect that they will continue to represent a significant portion of our total revenues for the foreseeable future. Our contract research revenues grew from $10.4 million in 2003 to $13.8 million in 2004 and to $15.4 million in 2005. In the first quarter of 2006, we generated contract research revenues of $3.9 million. As of March 31, 2006, our Contract Research Group was working on 68 contracts. In addition to these contracts, we regularly have a backlog of contracts for which work has been scheduled, but for which a specified portion of work has not yet been completed. We define backlog as the dollar amount of obligations payable to us under negotiated contracts upon completion of a specified portion of work that has not yet been completed, exclusive of revenues previously recognized for work already performed under these contracts, if any. The approximate value of our backlog was $15.7 million as of March 31, 2006.

Revenues from product sales currently represent a small proportion of our total revenues, and, historically, we have derived most of these revenues from the sales of our sensing systems and products that make use of light-transmitting optical fibers, or fiber optics. License revenues have been significant in the last three fiscal years due to the Luna Analytics, Luna Energy and Luna i-Monitoring transactions described below. Although we have been successful in licensing certain technology we do not expect license revenues to represent a significant portion of future revenues, however, over time we do intend to gradually increase such revenues. In the near term, we expect revenues from product sales to increase because of our acquisition of Luna Technologies on September 30, 2005. We also expect to increase our investments in product development and commercialization, which we anticipate will lead to increased product sales growth. In the future, we expect that revenues from product sales will represent a larger proportion of our total revenues and that as we develop and commercialize new products, these revenues will reflect a broader and more diversified mix of products.

In July 1998, we established Luna Technologies, and funded its growth by raising venture capital, which ultimately diluted our equity ownership to as little as approximately 7% during our holding period and to approximately 10% as of September 2005. In line with our strategy of building a growing portfolio of businesses and products, we acquired all of the outstanding shares in Luna Technologies we did not already own in exchange for issuing shares of our common stock in September 2005. Luna Technologies continues to operate as our Luna Technologies Division.

In February 2002, we established a joint venture limited liability company, Luna Energy, LLC together with Baker Hughes Oilfield Operations, Inc. Baker Hughes agreed to pay up to $32.0 million in connection with this joint venture as follows: $12.0 million in working capital contributed to Luna Energy over an estimated three-year collaboration period beginning in February 2002; $10.0 million to us, which we recognized as license revenues ratably over the expected collaboration period; and up to $10.0 million, which we earned including $1.5 million, $3.0 million and $3.5 million during the years ended December 31, 2002, 2003 and 2004, respectively, upon achievement of such milestones. In December 2004, Baker Hughes acquired our remaining equity interest in Luna Energy for a non-refundable payment of $990 thousand and the license arrangement was terminated.

In October 2003, IHS Energy Group, Inc. acquired rights to certain intellectual property related to our sensor technology and our equity interest in Luna i-Monitoring, Inc. Prior to and in connection with this transaction, we transferred certain non-intellectual property assets to Luna i-Monitoring. In connection with these transactions, IHS Energy Group agreed to pay the following amounts: $2.0 million in total working capital contributed to Luna i-Monitoring during the five years subsequent to the agreement; $300 thousand to Luna i-Monitoring’s creditors; $400 thousand to us in consideration for our transfer and license of intellectual property rights to IHS Energy Innovations; $100 thousand to us in consideration for our equity interest in Luna i-Monitoring; and $200 thousand to the other equityholders for their interests in Luna i-Monitoring. In addition, IHS Energy Group agreed to pay up to an aggregate of $6.5 million to the other equityholders and, following payment of the first $0.9 million of this amount, up to an aggregate of $2.5 million to us, based on a percentage of Luna i-Monitoring’s sales from December 1, 2003 through November 30, 2008. As of March 31, 2006, the other equityholders of Luna i-Monitoring have received $82 thousand in aggregate additional consideration based on $773 thousand in Luna i-Monitoring sales since

Management’s discussion and analysis of financial condition and results of operations

December 1, 2003. We have not received any additional consideration to date other than the $664 thousand that was paid at the date of the sale. In addition, we will not receive any additional consideration from Luna i-Monitoring unless aggregate Luna i-Monitoring product sales exceed $8.6 million prior to November 30, 2008, which amount would be inconsistent with historical sales to date. As a result, we do not anticipate that the amounts, if any, we may receive in the future from Luna i-Monitoring will be material to our business.

In December 2003, we entered into a product development agreement between our Luna Analytics, Inc. subsidiary and a biotechnology company. In connection with this arrangement, the biotechnology company agreed to pay the following amounts: $2.0 million contributed in working capital to Luna Analytics in 2004; $1.0 million to us, which we recognized as license revenues over the collaboration period from December 2003 to December 2004; and up to an aggregate of $6.0 million to us upon the achievement of certain milestones. We are entitled to receive certain payments in connection with sales of Luna Analytics products through December 2013. The aforementioned biotechnology company terminated its product development work as provided by the terms of the product development agreement on December 31, 2004. We have not received any payments pursuant to the terms of this agreement, and, as a result of the termination of the product development work, we do not currently expect to receive any payments in the future.

In June 2005, Luna Technologies entered into a Joint Cooperation Agreement with Luna Energy. Under this agreement, both parties have agreed to cooperate to develop a fiber optic sensing system product and have agreed to contribute materials, intellectual property, personnel and other resources to the development effort. Upon successful completion of product development, Luna Energy will receive a license to certain of Luna Technologies’ intellectual property and will be required beginning in 2007 and continuing through December 31, 2017 to make payments to Luna Technologies with respect to revenues derived from products sold that utilize this intellectual property. As of March 31, 2006, Luna Energy had not yet sold products that would entitle Luna Technologies to royalty payments under this joint cooperation agreement, Luna Technologies had received aggregate development milestone payments of $305 thousand as of that date under this agreement and is entitled to receive additional development milestone payments of up to $120 thousand in the aggregate, subject to the satisfaction of certain conditions. Luna Technologies also has the right to receive royalty payments from sales of products in the future. The license of certain of the intellectual property from Luna Technologies to Luna Energy shall be an exclusive license if Luna Energy makes certain minimum royalty payments of $420 thousand in the aggregate between 2007 and 2017, and shall be a non-exclusive license if Luna Energy fails to make these minimum royalty payments. Either party has the right to terminate this agreement during the development term (which, unless extended by mutual agreement of the parties, will expire June 6, 2006) upon a provision of advance written notice to the other party. However, if either party terminates the agreement for convenience or failure to meet certain development milestones, the terminating party may be required to grant license rights to the non-terminating party, including, where Luna Technologies is the terminating party, certain non-exclusive and certain exclusive rights with respect to intellectual property of Luna Technologies required to complete the development effort, and where Luna Energy is the terminating party, non-exclusive commercialization rights with respect to certain intellectual property of Luna Energy. Since December 2004, we have not held an ownership interest in Luna Energy. Luna Technologies continues to operate as our Luna Technologies Division after we acquired that entity in September 2005.

In connection with becoming a public company, we have and will incur significant additional expenses such as audit fees, professional fees, increased directors’ and officers’ insurance, advisory board and board of directors compensation, and expenses related to hiring additional personnel and expanding our administrative functions. Many of these expenses were not incurred by us in prior periods. We began to incur some of these expenses during the nine-month period ended March 31, 2006, and we expect that these expenses will continue to increase. In addition, upon receiving the net proceeds from our initial public offering, we intend to implement a strategy for expansion that will significantly increase our operating expenses and will likely create substantial losses. We incurred consolidated net losses of approximately $2.0 million and $2.1 million for the year ended December 31, 2005 and the three months ended March 31, 2006, respectively. We expect to continue to incur significant additional expenses as we expand our business, including increased expenses for research and development, sales and marketing, manufacturing, finance and accounting personnel and expenses associated with being a public company. We may also grow our business in part through acquisitions of additional companies and complementary

Management’s discussion and analysis of financial condition and results of operations

technologies which could cause us to incur greater than anticipated transaction expenses, amortization or write-offs of intangible assets and other acquisition-related expenses. As a result, we expect that we may likely continue to incur losses for the foreseeable future, and these losses could be substantial.

As a result of our board of directors’ decision to change the methodology for assessing the fair value of common stock underlying the equity awards granted subsequent to fiscal 2005, we have recorded a stock-based compensation charge for the three months ended March 31, 2006 of $409 thousand. We also expect to record an aggregate stock-based compensation charge of $5.8 million to be allocated over the years 2006 through 2009. For further information regarding this non-cash charge, see “—Reassessment of Fair Value.”

Description of Our Revenues, Costs and Expenses

Revenues

We generate revenues from contract research, product sales and license payments. We derive contract research revenues from providing research and development services to third parties, including government entities, academic institutions and corporations, and from achieving milestones established by some of these contracts and in collaboration agreements. In general, we complete contracted research over periods ranging from six months to three years, and recognize these revenues over the life of the contract as costs are incurred or upon the achievement of certain milestones built into the contracts. Our product revenues reflect amounts that we receive from sales of our products and currently represent a small portion of our total revenues. Our license revenues comprise up-front license fees paid to us in connection with licenses or sublicenses of certain patents and other intellectual property as well as royalties, which currently represent an insignificant portion of our license revenues.

Cost of Revenues

Cost of revenues associated with contract research revenues consists of research contract costs, including direct labor, amounts paid to subcontractors and overhead allocated to contract research activities.

Cost of revenues associated with product sales and license revenues consists of license fees for use of certain technologies; product manufacturing costs including all direct material and direct labor costs; amounts paid to our contract manufacturers; manufacturing, shipping and handling; provisions for product warranty; and inventory obsolescence, as well as overhead allocated to these activities. Product manufacturing activity is not yet a significant cost element due to our relatively low product sales activity in comparison with our other activities.

Operating Expense

Operating expense consists of selling, general and administrative expenses, as well as expenses related to research and development, depreciation of fixed assets and amortization of intangible assets. These expenses also include: compensation for employees in executive and operational functions including certain non-cash charges related to expenses from option grants; facilities costs; professional fees; salaries, commissions, travel expense and related benefits of personnel engaged in sales, product management and marketing activities; costs of marketing programs and promotional materials; salaries, bonuses and related benefits of personnel engaged in our own research and development beyond the scope and activities of our Contract Research Group; product development activities not covered by contracted research; and overhead costs related to these activities.

After completion of this offering, we anticipate our operating expenses will increase due to increased administrative costs for insurance, professional fees, external reporting requirements, Sarbanes-Oxley compliance and investor relations activities associated with operating as a publicly-traded company. These increases will also include the hiring of additional personnel.

Interest Expense

Interest expense historically related primarily to interest we paid under our senior secured revolving credit facility. As of March 31, 2006, there was no amount outstanding on our credit facility, and we do not expect to draw on that facility in the near term. Beginning the last week of 2005, interest expense includes interest accrued on the outstanding aggregate principal of the senior convertible promissory notes issued to Carilion Health System on December 30, 2005.

Management’s discussion and analysis of financial condition and results of operations

Critical Accounting Policies and Estimates

Our discussion and analysis of our financial condition and results of operations are based on our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States. The preparation of these financial statements requires us to make estimates, assumptions and judgments that affect the amounts reported in our financial statements and the accompanying notes. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances. Actual results may differ from these estimates under different assumptions or judgments. While our significant accounting policies are described in more detail in the notes to our consolidated financial statements included in this prospectus, we believe the following accounting policies to be critical to the judgments and estimates used in the preparation of our consolidated financial statements.

In the selection of our critical accounting policies, the objective is to properly reflect our financial position and results of operations for each reporting period in a consistent manner that can be understood by the reader of our financial statements. Our accounting policies and procedures are explained in note 1 of the notes to the consolidated financial statements contained elsewhere in this prospectus. We have identified the following as the most critical accounting policies which may have a significant effect on our reported financial results.

Contract Research Revenues

We recognize revenue when a contract has been executed, the contract price is fixed and determinable, delivery of services or products has occurred, and collectibility of the contract price is considered probable and can be reasonably estimated. Revenue is earned under cost reimbursable, time and materials and fixed price contracts. Direct contract costs are expensed as incurred.

Under cost reimbursable contracts, we are reimbursed for allowable costs, and paid a fixed fee. Revenues on cost reimbursable contracts are recognized as costs are incurred plus an estimate of applicable fees earned. We consider fixed fees under cost reimbursable contracts to be earned in proportion to the allowable costs incurred in performance of the contract.

Revenue on time and materials contracts are recognized based on direct labor hours expended at contract billing rates and adding other billable direct costs.

Fixed price contracts may include either a product delivery or specific service performance throughout a period. For fixed price contracts that are based on the proportionate performance method and involve a specified number of deliverables, we recognize revenue based on the proportion of the cost of the deliverables compared to the cost of the deliverables required by the contract. For fixed price contracts that provide for the development and delivery of a specific prototype or product, revenues are recognized on under the percentage of completion method in accordance with Statement of Position (SOP) 81-1 Accounting for Performance of Construction-Type and Certain Production-Type Contract.

Our contracts with agencies of the government are subject to periodic funding by the respective contracting agency. Funding for a contract may be provided in full at inception of the contract or ratably throughout the contract as the services are provided. In evaluating the probability of funding for purposes of assessing collectibility of the contract price, we consider our previous experiences with our customers, communications with our customers regarding funding status, and our knowledge of available funding for the contract or program. If funding is not assessed as probable, revenue recognition is deferred until realization is deemed probable.

Contract revenue recognition inherently involves estimation, including the contemplated level of effort to accomplish the tasks under the contract, the cost of the effort, and an ongoing assessment of progress toward completing the contract. From time to time, as part of the normal management processes, facts develop that require revisions to estimated total costs or revenues expected. The cumulative impact of any revisions to estimates and the full impact of anticipated losses on any type of contract are recognized in the period in which they become known.

Management’s discussion and analysis of financial condition and results of operations

The underlying bases for estimating our contract research revenues are measurable expenses such as labor, subcontractor costs and materials, the cost data of which is updated on a regular basis for purposes of preparing our cost estimates. Our research contracts generally have a period of performance of six to 18 months. Accordingly, our estimates of contract costs have historically been consistent with actual results. Revisions in these estimates between accounting periods to reflect changing facts and circumstances have not had a material impact on our operating results, and we do not expect future changes in these estimates to be material.

The allowability of certain costs under government contracts is subject to audit by the government. Certain indirect costs are charged to contracts using provisional or estimated indirect rates, which are subject to later revision based on government audits of those costs. Management is of the opinion that costs subsequently disallowed, if any, would not be significant.

Deferred Taxation

We estimate our tax liability through calculations we perform for the determination of our current tax liability, together with assessing temporary differences resulting from the different treatment of items for tax and accounting purposes. These differences result in deferred tax assets and liabilities, which are recorded on our balance sheet. Management then assesses the likelihood that deferred tax assets will be recovered in future periods. In assessing the need for a valuation allowance against the net deferred tax asset, we consider factors such as future reversals of existing taxable temporary difference, taxable income in prior carryback years, if carryback is permitted under the tax law, tax planning strategies and future taxable income exclusive of reversing temporary differences and carryforwards. To the extent that we cannot conclude that it is more likely than not that the benefit of such assets will be realized, we establish a valuation allowance to adjust the net carrying value of such assets.

As we assess the sufficiency of future taxable income and other factors noted above in future periods, our estimate of the required valuation allowance may change, which could have a material impact on the accounting period(s) in which the change occurs.

Stock-Based Compensation

Prior to January 1, 2006, we recorded compensation expense under the intrinsic value method, pursuant to APB 25 and related interpretations, whenever the exercise price of an option grant was less than the fair market value of our common stock on the grant date. We recorded compensation expense whenever we modified the terms of an option grant or directly or indirectly repriced outstanding options. Our board of directors is responsible for determining the fair value of our common stock for the purpose of establishing exercise prices for our option grants. Our board has relied upon Market Place Transaction History as well as the assistance from independent valuation specialists for purposes of estimating the fair value of our common stock.

In August 2003, our board of directors authorized an option exchange program whereby holders of options for Class A Common Stock were given the opportunity to exchange their options for options to purchase Class B Common Stock on a one-for-one basis. The new option grants were immediately vested on September 29, 2003, the date of exchange, had an exercise price of $0.35 and a life of 10 years from the date of grant. All of the outstanding options issued under this exchange program had exercise prices in excess of the fair value of our Class A Common Stock as of the date of the exchange. As such, the option exchange was accounted for as a repricing in accordance with FIN 44. We are required to apply variable plan accounting to the replacement grant and measure compensation based on the change in fair value of the common stock at each reporting period. A total of 27,107 shares subject to such options exchanged under this program remain outstanding as of March 31, 2006. We will continue to incur a non-cash charge or benefit each quarter based upon the increase or decrease in fair value of our common stock, until such options are exercised, forfeited or expire.

Management’s discussion and analysis of financial condition and results of operations

The fair value of common stock for options granted was estimated by the Compensation Committee of our board of directors, applying a number of commonly accepted valuation methodologies. The board of directors also considered valuations performed by an independent third-party valuation specialist.

We currently anticipate granting stock options to our officers, directors and employees subsequent to the consummation of this offering. The exercise price of the options will be equal to the price per share to the public at the time of the grant.

Effective January 1, 2006, we adopted Financial Accounting Standards No. 123R, Share Based Payment (SFAS No. 123R) using the modified prospective transition method. Under this transition method, our financial statements for periods prior to January 1, 2006 will not be restated. However, new awards and awards modified, repurchased or cancelled after January 1, 2006 will trigger compensation expense based on the fair value of the stock option as determined by an option pricing model. We will amortize stock-based compensation for such awards on a straight-line method over the related service period of the awards taking into account the effects of the employees’ expected exercise and post-vesting employment termination behavior.

Reassessment of Fair Value

From time to time, our board of directors grants stock options to employees, directors and consultants. At the time we granted stock options, we believed that the per share exercise price of options to purchase our Class B Common Stock approximated the fair value of that stock on the grant date. However, in connection with the preparation of the financial statements for our initial public offering and solely for the purposes of accounting for employee stock-based compensation, we considered whether the equity awards granted subsequent to December 31, 2005 had a compensatory element that should be reflected in our financial statements. We noted that the fair value of the shares subject to the equity awards granted during this period, as determined by our board of directors at the time of grant and principally based upon the valuation reports, were significantly less than the valuations that our underwriters were discussing with us in connection with our preparation for this offering. We believed we should consider the discrepancies in valuation in determining whether the equity awards granted during this time had a compensatory element. As a result, we applied hindsight to reassess the fair value of our Class B Common Stock for all equity awards granted subsequent to December 31, 2005.

In assessing the fair value of the shares of Class B Common Stock underlying the equity awards granted subsequent to fiscal 2005, our board of directors used valuation methodologies it believes are consistent with the practices recommended by the AICPA Audit and Accounting Practice Aid Series Valuation of Privately-Held-Company Equity Securities Issued as Compensation, or the practice aid. The board reviewed the guidance set forth in the practice aid and determined that using the annual valuation reports was a reasonable starting point for assessing the value of the common stock. In making this determination, the board noted that during the review period there were no quoted market prices in active markets for the Class B Common Stock and there were no arms’-length cash transactions with unrelated parties for issuances of such securities. In these circumstances, the practice aid recommends engaging an unrelated valuation specialist for the purpose of assisting management in determining fair value of common stock. The board also noted that the annual valuation reports contained all of the required content for valuation reports outlined in the practice aid, as well as much of the additional content recommended to be included.

In light of the recommendations detailed in the practice aid, the board initially decided to give substantially more weight to the valuation reports than the underwriters’ anticipated initial public offering price in assessing equity award valuations. Nonetheless, the board also determined that it should examine the underlying assumptions made in the valuation reports to determine whether these assumptions were appropriate as of the dates the equity awards were granted after taking into consideration our circumstances on each date. After much consideration, our board of directors decided that the valuations provided by the underwriters was a better indication of fair value of the Company’s Class B Common Stock, and that such value should be used to measure compensation expense associated with fiscal 2006 option grants.

Management’s discussion and analysis of financial condition and results of operations

Based upon this reassessment of fair value of our Class B Common Stock, we have recorded a stock-based compensation charge under the fair value method outlined in SFAS 123R using the revised fair value of our Class B Common Stock as an input in such calculation. The approximate amount of stock-based compensation based upon the reassessed fair value of Class B Common Stock underlying the stock option awards recognized for the three months ended March 31, 2006 and expected to be recognized in the period of 2006 through 2009 is $409 thousand and $5.8 million, respectively.

The aggregate amount of stock-based compensation expected to be recognized during the years 2006 through 2009 will be allocated as follows:


	2006	2007	2008	2009
Amortization of stock-based compensation related to stock options granted	$1,339,000	$1,506,000	$1,506,000	$1,455,000

Results of Operations

Three Months Ended March 31, 2006 Compared to Three Months Ended March 31, 2005

Revenues

Total revenues increased 38.7% to $4.5 million for the three months ended March 31, 2006 from $3.3 million for the three months ended March 31, 2005. The increase was due in part to increased product sales related to our Luna Technologies Division, which was not acquired until September 30, 2005 and thus was not yet reflected in the results of our consolidated operations for the first quarter of 2005. Our acquisition of Luna Technologies and the subsequent product sales by that division is a key element of our strategic transition towards increased product sales revenues. We generated approximately $595 thousand in product sales in the first quarter of 2006 as compared with no such product sales revenues in the first quarter of 2005.

Growth in our contract research revenues also contributed to our overall revenues growth for the first quarter of 2006 as compared with the first quarter of 2005. Contract research revenues increased 20.4% to $3.9 million for the three months ended March 31, 2006 from $3.3 million for the same period in 2005. This increase was primarily a result of an improved success rate in obtaining research contract awards and in an increase in the size of certain awards, both of which in particular occurred in our Luna nanoWorks Division. This increase in success rate was driven in part by application of proceeds from the Carilion financing, which enabled us to devote more resources to pursuing contract awards.

Cost of Revenues

Cost of revenues increased 18.8% to $3.2 million for the three months ended March 31, 2006 from $2.7 million for the three months ended March 31, 2005. This increase was consistent with our overall increase in revenues. The main component of this overall increase was the inclusion of product sales costs due to the operations of our Luna Technologies Division during the first quarter of 2006; these costs were not previously a component of our operations in the first quarter of 2005. New product sales costs accounted for approximately $266 thousand, or over half, of the overall increase in costs of revenues.

Contract research costs increased 8.9% to $2.9 million for the three months ended March 31, 2006 from $2.7 million in the same period in 2005. This increase was consistent with but slightly less than the increase in our contract research revenues.

Despite the inclusion of product sales costs in our cost of revenues in the first quarter of 2006, our overall gross margin improved as compared with the first quarter of 2005. Our overall gross margin during the three months ended March 31, 2006 was 29.7%, which is an increase from 18.0% during the same period in 2005. During the three months ended March 31,

Management’s discussion and analysis of financial condition and results of operations

2006, contract research activity returned a gross margin of approximately 25.8%, while product sales activity returned an even-greater gross margin of 55.3%. Our objective of seeking greater relative product sales is based on the goal of achieving higher margins to improve our overall profitability.

Operating Expense

Operating expense increased 290.5% to $3.4 million for the three months ended March 31, 2006 from $882 thousand for the corresponding quarter in 2005. Much of the increase in the first quarter of 2006 as compared to the same period in 2005 was due to significant indirect expenses in connection with our general restructuring towards increasing our product sales capabilities as well as in anticipation of our initial public offering and the subsequent obligations as a public company. Consistent with our strategy of building a growing portfolio of businesses and products, we were and are actively hiring additional staff, incurring professional fees and implementing various internal changes to prepare and strengthen our existing infrastructure and management resources during and after our transition to being a public company. With the completion of our financing round with Carilion Health System in December 2005, we gained the necessary resources to begin implementing many of these important changes to our business. We expect that our operating expenses will remain at these increased levels and perhaps increase further in the coming months due to our continued growth and development as well as due to the indirect costs of our initial public offering and compliance with the various reporting requirements of being a publicly-traded company.

Another significant factor in the increase in our operating expense between the first quarter of 2005 and the first quarter in 2006 was our adoption of SFAS No. 123R, which required us to record expense related to the increase in fair market value of options outstanding. We recorded share-based compensation expense of approximately $409 thousand during the three months ended March 31, 2006, part of which is the result of adoption of this new accounting policy.

Other Income (Expense)

The increase in other income (expense) was a result of our acquisition of the remaining outstanding equity of Luna Technologies as of September 30, 2005. Subsequent to that date, the operating results of Luna Technologies was consolidated with our operating results, including during the three months ended March 31, 2006. During the three months ended March 31, 2005, our interest in the losses of Luna Technologies was reflected as investment losses, a component of other income (expense), consistent with our accounting policies.

Net interest income (expense) increased from a net expense during the three months ended March 31, 2005 to net income during the same period in 2006. Nearly all of the interest expense during the three months ended March 31, 2006 was incurred on our senior convertible promissory notes issued to Carilion Health System on December 30, 2005 that were not previously outstanding during the first quarter of 2005. These notes have an aggregate outstanding principal of approximately $5.0 million and accrue simple interest at a rate of 6.0% per year. During the three month period ended March 31, 2006, interest expense on such notes was approximately $75 thousand. At the same time, the proceeds from the issuance of the senior convertible promissory notes and the proceeds from the sale of our Class C Common Stock received at the beginning of the first quarter in 2006 provided a cash surplus for us. These proceeds resulted in our holding greater interest-bearing balances in the three months ended March 31, 2006 than during the same period in 2005. Finally, during the first quarter of 2006, we did not have an outstanding balance on our line of credit, which otherwise permits us to borrow up to $2.5 million. As such, we did not incur interest expense on that line of credit in 2006 unlike in 2005, during which we had an outstanding balance throughout the quarter at an overall borrowing rate greater than that of the Carilion Health System notes. We do not anticipate a need to draw on that line of credit in the near term given the funds raised from our August and December 2005 financing rounds with Carilion Health System, as well as the generation of proceeds from this offering.

Management’s discussion and analysis of financial condition and results of operations

Year Ended December 31, 2005 Compared to Year Ended December 31, 2004

Revenues

Total revenues decreased 27.2% to $16.5 million for the year ended December 31, 2005 from $22.6 million for the year ended December 31, 2004. The decrease was a result of the absence of license revenues relating to our arrangement with Baker Hughes. The satisfaction of our right to receive certain milestone payouts in connection with that arrangement and the sale of our interest in Luna Energy to Baker Hughes in December 2004 represents the completion of our licensing arrangement with Baker Hughes. The decrease in license revenues was offset in part by an increase in contract revenues during the year ended December 31, 2005 as compared with the same period in 2004. During 2005, consistent with our business plan, we did not receive significant license payments for our technologies, and we do not expect license revenues comparable to those in 2002, 2003 and 2004 in the near term. We do, however, expect that product revenues will increase in the near term as a result of our acquisition of Luna Technologies on September 30, 2005. The acquisition of Luna Technologies was consistent with our strategy to transition our revenues mix from contract research revenues to product sales and license revenues. We generated approximately $1.1 million in product sales in 2005, virtually all of which were derived from operations of Luna Technologies subsequent to our acquisition.

Although total revenues decreased due to the cessation of revenues from the Luna Energy joint venture in December 2004, contract research revenues increased 11.2% to $15.4 million for the year ended December 31, 2005 from $13.8 million for the same period in 2004. This increase reflects our continued short-term commitment to steady and consistent growth of our contract research business while, at the same time, we seek to increase our product sales both in absolute terms and as a proportion of total revenues.

Cost of Revenues

Cost of revenues decreased 6.5% to $13.0 million for the year ended December 31, 2005 from $13.9 million for the year ended December 31, 2004. Consistent with our decrease in revenues, the decline was primarily driven by the lack of licensing revenues as our licensing arrangement with Baker Hughes was completed at the end of 2004.

Contract research cost of revenues increased 14.3% to $12.6 million for the year ended December 31, 2005 from $11.0 million in the same period in 2004. This increase was consistent with a corresponding increase in contract research revenues.

Cost of product sales and license cost decreased 85.8% to $410 thousand for the year ended December 31, 2005 from $2.9 million in the same period in 2004. This decrease was due to the cessation of license cost activity in 2005 with the completion of the Luna Energy joint venture in December 2004. Nearly all of the costs in this area incurred in 2005 were cost of product sales, which were driven by our increased product sales through our Luna Technologies Division beginning in the fourth quarter of 2005.

Operating Expense

Operating expense increased 43.3% to $6.0 million for the year ended December 31, 2005 from $4.2 million for the year ended December 31, 2004. The increase in operating expense was primarily attributable to our acquisition of Luna Technologies and the related indirect transaction and integration costs. Additionally, we incurred significant expenses in connection with our planned initial public offering that are not direct costs and are not otherwise capitalizable. These include hiring increased staff, professional fees and various other internal changes designed to supplement and enhance our existing infrastructure and human resources. The activity in 2005 is in line with our strategy of building a growing portfolio of businesses and products. We expect that our operating expenses will continue to increase in the coming months due to the indirect costs of our initial public offering and continued compliance with the various reporting requirements of being a publicly-traded company.

Management’s discussion and analysis of financial condition and results of operations

Other Income (Expense)

The decrease in other expense was primarily a result of a decrease in losses from equity method investees. We disposed of our investment in Luna Energy in December 2004 and acquired Luna Technologies in September 2005. For 2004, our pro rata portion of the losses of Luna Technologies was reflected in other income (expense) because Luna Technologies was accounted for as an equity-method investment. Our share of losses in Luna Technologies from January 1, 2005 to September 30, 2005, the acquisition date, was nominal. Luna Technologies’ operating results from the acquisition date through the end of the period have been included in our consolidated operating results.

Interest expense decreased from 2004 as a result of paying down the line of credit in 2003. Our line of credit permits us to borrow up to $2.5 million. We do not anticipate a need to draw on the line of credit in the near term given the funds raised from our August and December 2005 financing rounds with Carilion Health System, as well as the generation of proceeds from this offering. We did not recognize substantial interest expense related to the senior convertible promissory notes issued to Carilion Health System on December 30, 2005 as such notes were only outstanding for one day during the period.

Year Ended December 31, 2004 Compared to Year Ended December 31, 2003

Revenues

Total revenues increased 28.4% to $22.6 million in 2004 from $17.6 million in 2003. This increase was largely driven by growth in our volume of research contracts. Contract research revenues increased 33.6% to $13.8 million in 2004 as compared with $10.4 million in 2003. During 2003, we undertook an initiative to improve our ability to obtain additional contracts by devoting increased resources to support our Contract Research Group. Much of the result from these efforts in 2003 is reflected in our 2004 revenues because of a lengthy bidding process and because our contract research may take several months and sometimes years to complete. The length of our contract research efforts under a typical contract ranges from six months to three years. In addition to the growth of our existing contract research, we also experienced an increase in research contract volume in connection with the creation of our Luna nanoWorks Division. Contracts under our Luna nanoWorks Division accounted for approximately $337 thousand of the overall increase in our contract research revenues, while growth of our existing contract research business accounted for the remaining $3.1 million of such increase.

Product sales and license revenues also contributed significantly to our total revenues growth during this period. Product sales and license revenues increased 21.0% to $8.8 million in 2004 from $7.2 million in 2003. Much of this increase is the result of achieving milestones under the Luna Energy license agreement. As a result of the sale of our remaining interest in Luna Energy to Baker Hughes in December 2004, we do not expect license revenues to be significant in the near term. Revenues related to product sales represent a small proportion of our total revenues in 2004 and 2003. During that period, we continued to remain focused on our contract research business.

Cost of Revenues

Cost of revenues increased 32.1% to $13.9 million in 2004 from $10.5 million in 2003, with most of the increase directly attributable to increased volume of research contracts. Cost of contract research revenues, however, increased at a slightly lower rate of 22.7%, from costs of $8.9 million in 2003 to costs of $11.0 million in 2004. As our contract research volume increased, the costs related to these contracts also increased. However, as the volume of contracts increase, we also benefit from economies of scale. Accordingly, our costs of contract research for this period increased at a lower rate than the corresponding revenue growth.

In addition to our increased contract research activity, we also incurred increased license costs due to certain bonuses accrued and paid in 2004 to contributors and providers of intellectual property related to the Luna Energy joint venture. In December 2004, we sold our remaining interest in Luna Energy to Baker Hughes. In connection with that sale and the receipt of payments for achievement of certain milestones in connection with that venture, we paid bonuses to the technology partners from whom we licensed part of the intellectual property for the venture. Accordingly, the cost of our product sales and license revenues increased 86.7% to $2.9 million in 2004 as compared with $1.5 million in 2003. Although this increase

Management’s discussion and analysis of financial condition and results of operations

outpaced the percentage increase license and royalty revenues between 2003 and 2004, it is consistent with the overall growth in license and royalty revenues between 2002 and 2004, during which period the Luna Energy joint venture took place.

Operating Expense

Operating expenses decreased 13.7% to $4.2 million in 2004 from $4.9 million in 2003 as we were able to increase revenues year-over-year with no significant changes in our operating infrastructure as well as incurring fewer costs related to outside transactions. In 2003, we sold our interest in Luna i-Monitoring. No similar transactions occurred in 2004. Additionally, as our operations have become more mature, we have been able to substantially reduce operating expenses due to the increased use of long-term contracts and leases as well as to our improved ability to predict the needs of our operations.

Other Income (expense)

Our share of losses from equity method investees increased approximately $107 thousand as a result of advances made to such investees during the year which provided us basis to record such cases.

Interest expense remained consistent for the years ended December 31, 2004 and 2003.

Liquidity and Capital Resources

Prior to August 2005, our primary source of liquidity had been cash provided by operations and divestitures of certain assets and businesses. In August 2005, we completed our first outside equity financing and raised $7.0 million through an equity investment by Carilion Health System. Carilion Health System invested an additional $8.0 million in December 2005 in the form of $5.0 million aggregate principal amount of senior convertible promissory notes and $3.0 million in additional equity. Our principal uses of cash have been to fund our expansion, including facilities, personnel, working capital and other capital expenditures.

We have a $2.5 million senior secured revolving credit facility with First National Bank that is collateralized by a security interest in substantially all of our assets. The interest rate on borrowings under our secured revolving credit facility is equal to the prime rate, limited to no less than 6.0% and no greater than 10.0% per annum, and the interest accrued is payable monthly. Under the terms of the senior secured revolving credit facility, the outstanding principal is payable in full on demand or at maturity on May 30, 2006. The senior secured revolving credit facility contains covenants which require us to maintain $1.0 to $2.0 million in liquidity depending on our outstanding balance. Additionally, without First National Bank’s prior approval, we may not make a direct loan to an affiliate or subsidiary of ours exceeding $500 thousand annually, guaranty the debt of our affiliate or subsidiary or incur debt in excess of $200 thousand non-First National Bank debt annually. Finally, we are obligated to continue to provide First National Bank an assignment of life insurance in a minimum amount of $1.0 million on the life of Kent A. Murphy, covering all of our indebtedness to First National Bank. As of December 31, 2005, we had repaid the outstanding balance on our secured revolving credit facility, and we do not anticipate a need to draw on that line of credit in the near term given the funds raised from our August and December 2005 financing rounds with Carilion Health System as well as the proceeds from this offering. With the exception of our obligations under our senior secured revolving credit facility and our capital lease, we have no other debt outstanding.

Discussion of Cash Flows

Recent Activity

During the three months ended March 31, 2006, we used approximately $2.1 million of net cash from operations. This was a substantial change over the activity in the corresponding quarter of 2005. Most of this change was due to the addition of operations from the Luna Technologies Division, which was not reflected in the cash flows from operations in the first quarter of 2005, and the general increase in cash outflows that resulted from our expenditures increase to achieve a greater relative amount of product sales and our preparation to become a public company. We note that cash flows from operations excludes the effect of the non-cash share-based compensation charge we recorded during the period.

Cash used in investing activities for the three months ended March 31, 2006 related primarily to the purchase of property and equipment and legal fees associated with securing patent rights to certain technology. Our overall cash used in investing

Management’s discussion and analysis of financial condition and results of operations

activities slightly declined in the first quarter of 2006 as compared with the first quarter in 2005. This was due mostly to the recent addition of our Luna Technologies Division, which was acquired in a non-cash transaction. The acquisition of Luna Technologies represented a substantial increase in our capacity that slightly reduced our need for continued investment growth in the first quarter of 2006. Upon completion of this offering, we expect an increase in net cash used in investing activities as we will have the necessary resources to begin and complete a number of longer-term investments in our growth.

Cash flows from financing activities for the three months ended March 31, 2006 were very limited. During the year ended December 31, 2005, we received proceeds of approximately $10.0 million from two equity financing arrangements with Carilion Health System, as well as an additional $5.0 million from the issuance of senior convertible promissory notes to Carilion Health System. These investments represented our first major round of venture financing. As a result of our increased cash position through that financing at the end of 2005, we did not need to draw additional financing from our line of credit or other sources in the first quarter in 2006 as we had previously done in the first quarter of 2005.

At March 31, 2006, total cash and cash equivalents were approximately $10.1 million. We believe that our current cash on hand, cash available under our line of credit agreement and the proceeds we expect to generate from our initial public offering will be sufficient to fund operations for the next 12 months.

Significant Liquidity Events

In March 2004, we received a grant of $900 thousand from the City of Danville, Virginia under a Grant Agreement to support the expansion of economic and commercial growth within the City. Under the Grant Agreement, we agreed to locate a nanomaterials manufacturing and research facility and maintain its operations in Danville until March 25, 2009. We agreed under the Grant Agreement to invest at least $5.2 million in capital equipment expenditures and $1.2 million in certain facilities by September 25, 2006 and to maintain such investments in our Danville facility until March 25, 2009. We also agreed to create by September 25, 2006 at least 54 new full-time jobs at the Danville facility at an average annual wage of at least $39 thousand plus benefits, and to maintain these jobs at such facility until March 25, 2009. If we fail to make these capital expenditures and create these jobs by September 25, 2006, we will be obligated to repay the City of Danville all or a portion of the funds based on a formula of the pro rata shortfall of such expenditures and jobs falling below such required levels. These contractual requirements will restrict the use of significant assets and could obligate us to an annual payroll obligation exceeding $2.0 million until March 25, 2009. To the extent such hiring results in salaries in excess of the required minimum wages, our annual payroll obligation could be substantially greater than $2.0 million. At this time, we do not anticipate that we will satisfy the investment and hiring targets of the grant prior to September 25, 2006, and we expect that we may have to return some or all of the grant proceeds. We currently have classified the full amount of the grant as a liability on our balance sheet in anticipation of returning the funds.

In August 2005, we entered into a Class C Common Stock financing agreement with Carilion Health System, or Carilion, whereby Carilion committed to providing approximately $15.0 million in equity financing in three tranches subject to certain conditions outlined in the agreement. In connection with this transaction, Carilion purchased shares of our Class C Common Stock for an aggregate purchase price of $7.0 million. On December 30, 2005, we reached an agreement with Carilion to terminate the August 2005 financing agreement and enter into a new Class C Common Stock financing agreement. Under the new agreement, Carilion provided $5.0 million in exchange for five $1.0 million senior convertible promissory notes, and $3.0 million in exchange for shares of Class C Common Stock. The notes are convertible into Class C Common Stock at a rate of $4.69159 per share and bear interest at 6% per annum and mature on December 30, 2009. As of March 31, 2006, we had received the full $15.0 million in proceeds from the issuance of such notes and the sale of our Class C Common Stock pursuant to our financing agreements with Carilion Health System.

Long-term debt obligations consist of senior convertible promissory notes of aggregate principal amount of $5 million and interest thereon held by Carilion Health System and a secured promissory note of aggregate principal amount of $214,955 and interest thereon held by the Virginia Tech Foundation.

In March 2004, we received a $900 thousand grant from the City of Danville, Virginia to be used for the expansion of economic and commercial growth within the City. Specifically, $450 thousand of the grant will be used to offset certain capital expenditures for leasehold improvements being made at our Danville facility, and the remaining $450 thousand is to be used for our creation of new jobs.

The grant stipulates that we must make estimated capital expenditures of at least $6,409,000 and create 54 new full time jobs at our Danville facility, at an average wage of at least $39 thousand plus benefits within 30 months of the award, and then maintain such employment levels for an additional 30 months. We could be required to repay the grant funds on a pro-rata basis should we fail to satisfy the conditions stipulated in this agreement by September 25, 2006 at the earliest. As such, since we have not yet met the stipulations of the grant, we have included the $900 thousand in deferred credits in the accompanying consolidated balance sheets as of December 31, 2004 and 2005.

Quantitative and Qualitative Disclosures about Market Risk

Market risk represents the risk of loss that may impact our financial position due to adverse changes in financial market prices and rates. We do not hold or issue financial instruments for trading purposes or have any derivative financial instruments. To date, all payments made under our research contracts are denominated in United States dollars. Our exposure to market risk is limited to interest rate fluctuations due to changes in the general level of United States interest rates, particularly because the interest rate on our line of credit is variable between 6.0% and 10.0% based on the current prime rate of interest. As of March 31, 2006, our cash reserves were maintained in money market investment accounts and were not exposed to material market risks.

Business

Overview

We research, develop and commercialize innovative technologies in two primary areas: molecular technology solutions and sensing solutions. We have a disciplined and integrated business model that is designed to accelerate the process of bringing new and innovative products to market. We identify technologies that can fulfill large and unmet market needs and then take these technologies from the applied research stage through commercialization in our two areas of focus:

Our aggregate revenues from January 1, 2003 through March 31, 2006 were $61.1 million, and our aggregate cost of revenues during that same period were $40.5 million. However, we had a net losses of $2.0 million and $2.1 million for the year ended December 31, 2005 and the three months ended March 31, 2006, respectively, and we expect to incur significant additional expenses as we expand our business. We also expect significantly greater losses for the foreseeable future primarily due to increased expenditures related to our nanomaterial and medical device product development efforts.

Contract Research Group. Our Contract Research Group provides applied research to customers in our areas of focus. Our engineers and scientists collaborate with our network of government, academic and industry experts to identify technologies and ideas with promising market potential. After these promising technologies are identified, our Contract Research Group competes to win fee-for-service contracts from government agencies and industrial clients who seek innovative solutions to practical problems that require new technology. We focus primarily on contract research opportunities where we can retain partial or full rights to the intellectual property developed, and generally obtain full funding of the costs of contracts we undertake from our customers. This approach allows us to cover the costs of early-stage technology development with contract research revenues. Our contract research revenues grew from $10.4 million in 2003 to $15.4 million in 2005, representing 48.5% total growth over that period, while our contract research costs increased from $8.9 million in 2003 to $12.6 million in 2005, representing a total increase of 40.3% over that period. These revenues have in general been a growing part of our business from inception, and our Contract Research Group seeks to continually supply our product pipeline with new opportunities.

Business

Contract Research Group, our Commercialization Strategy Group develops detailed business plans for commercially viable products. It is at this stage that we first consider investing our own funds to finance the continued development of a product, which is then managed in our Products Group.

Products Group. Our Products Group currently consists of the following three divisions:

Luna Technologies Division. Our Luna Technologies Division manufactures and markets test and measurement equipment and integrated sensing solutions. This division’s products are used for process and control monitoring in telecommunications, manufacturing, power generation and distribution, down-hole oil and gas production, aerospace, and defense applications. These products have won numerous awards and are sold and distributed throughout North America, Europe, the Middle East and Asia.

We have knowledge and experience in molecular technology solutions and sensing solutions and, as of March 31, 2006, we owned or had exclusive rights to use 39 issued U.S. patents and 63 additional pending U.S., international and foreign patent applications. As of March 31, 2006, approximately 90 of our 161 employees were directly engaged in research in our Contract Research Group, of whom 31 hold Ph.D.s and 34 hold advanced degrees.

Industry Background and Market Opportunity

Molecular Technology Solutions

Our molecular technology solutions generally utilize advanced materials with enhanced performance characteristics. These materials are produced by harnessing unique chemical, physical and biological properties through novel combinations of matter and include metals, ceramics, nanomaterials, composites and polymers, which are materials made up of smaller, linked building blocks. Nanotechnology, which focuses on manipulating materials at the atomic scale to create advanced materials with novel properties, is itself a broad field and many national governments have made a priority of supporting nanotechnology research and development. According to the National Nanotechnology Initiative, since the inception of the U.S. National Nanotechnology Initiative in 2001, the U.S. government has invested $4 billion to support nanotechnology research and development activities.

Business

In general, advanced materials enable significant improvements in the performance, cost and functionality of existing products and allow the development of products not previously possible. Such materials have potential applications in many industries, including semiconductors, electronics, biotechnology, textiles, alternative energy and defense. Some advanced material products that are currently being developed include: very high density and cost efficient digital memories; smart sensors; pharmaceuticals; drug delivery systems; cost efficient fuel cells, solar cells and light sources; stain resistant textiles; lightweight, high strength composites for civil and military applications; and wear resistant and anti-corrosion coatings for industrial applications.

In 2004, the market sizes of the following advanced material subsectors—coatings and flame retardants—were estimated to be approximately $9.5 billion and $1.6 billion, respectively, according to Chemical Week. In 2005, the market sizes of the following advanced material subsectors—ceramics and composites—were estimated to be approximately $2.0 billion and $4.8 billion, respectively, according to Electronics.ca Publications and the Market Leaders- Cook Composites and Polymers report.

Sensing Solutions

Our sensing solutions involve the integration of multiple technologies to design, manufacture and commercialize new products. Such products require a broad range of expertise and technical competencies, including research and development, engineering design, software programming and product testing. Our optical, ultrasound and wireless sensing solutions address a wide variety of end markets including defense and military, healthcare, telecommunications, industrial measurement, security applications and consumer electronics. We believe that Homeland Security-related applications are one of the most attractive sensing solutions markets given recent increases in government investment in this area. For example, the research and development budget of the U.S. Department of Defense was expected to reach $70.0 billion in 2005 according to the American Association for the Advancement of Science.

Examples of sensing solutions products include industrial and military sensors to increase equipment operating efficiency, perimeter and impact detection systems, diagnostic systems for telecommunications networks, devices to measure physical properties of materials for medical and industrial applications and secure wireless communication systems.

Many of these end markets represent very large opportunities. For example, in 2004, the market sizes of the following sensing solutions sub-sectors—industrial sensors and electromechanical actuator systems—were estimated to be approximately $4.2 billion and $7.1 billion, respectively, according to Electronic Business.

Opportunity to Accelerate the Commercialization of Technology

Technology innovation is a key engine for growth in an increasingly global and competitive marketplace. According to the National Science Foundation, over $312.0 billion was spent in research and development in the United States in 2004 as follows: $93.4 billion by federal agencies, $199.0 billion by the private sector, $11.1 billion by academic institutions and $8.6 billion by not-for-profit organizations.

However, the transition from technology discovery to commercialization is challenging, and government agencies, academic institutions and corporations frequently lack formal processes to enable timely commercialization of technologies in response to marketplace demands. One problem is that research and development is often done in isolation, without input or feedback from the marketplace. In addition, due to the inherent complexity of new technologies, cross-disciplinary and integration issues are often not addressed because researchers, engineers and product developers have very specialized areas of expertise. Moreover, research organizations may be unable to commercialize technologies because their networks may not be broad or deep enough to connect them expeditiously with partners, investors and customers. Development efforts can also fail for a host of other reasons, such as inability to manufacture at commercial scale, unanticipated competition or poorly understood customer needs.

Business

Technology innovation in areas such as molecular technology solutions and sensing solutions is particularly susceptible to these challenges because it requires expertise across a number of technical disciplines, which are often isolated from each other. We have developed a model for technology innovation that addresses these issues and that we believe has the potential to significantly accelerate the creation and commercialization of new technologies.

Our Business Model

We have developed a disciplined and integrated process to accelerate the development and commercialization of innovative technologies. Our business model employs a market-driven approach and provides the infrastructure, resources and know-how throughout the process of developing and commercializing new products. To manage a diverse set of products effectively across a range of development stages, we are organized into three main groups: our Contract Research Group, our Commercialization Strategy Group and our Products Group. These groups work together through all product development stages, including:

Searching for emerging technologies based on market needs;

Conducting applied research;

Developing and commercializing innovative products; and

Applying proven technologies and products to new market opportunities.

The graphic below illustrates our business model:

LOGO

The strength of our business model is exemplified by our track record in taking innovative technologies from the applied research stage through product development and ultimately to the creation of independent businesses. For example, we have created five companies in our areas of focus, sold two of them to industry leaders in their fields, raised private capital for two of our companies and formed one joint venture. In addition, we have developed more than a dozen products serving several

Business

industries including energy, telecommunications, life sciences and defense. We describe below three examples of independent businesses that we have created:

Luna Analytics, Inc. In June 1999, we created Luna Analytics to commercialize analytical instruments that improve the assessment of protein interactions. Luna Analytics’ devices are being developed to provide advanced disease diagnostics, treatment and drug discovery. We currently own approximately 39% of Luna Analytics.

Luna Energy, LLC. In February 2002, we created Luna Energy to commercialize real-time, state-of-health pipeline monitoring sensors for the oil and gas industry. Luna Energy was acquired in December 2004 by Baker Hughes Oilfield Operations Inc., a leader in oil field services. We no longer have an ownership interest in Luna Energy, but our Luna Technologies Division is entitled to receive payments from Luna Energy in connection with future product sales beginning in 2007.

Luna i-Monitoring, Inc. (now IHS i-Monitoring). In May 2002, we created Luna i-Monitoring to commercialize a suite of highly integrated wireless sensors called iNodes for cost-effective remote monitoring and Internet accessibility for the oil and gas marketplace. Luna i-Monitoring was acquired by IHS Energy, Inc. in October 2003, and therefore we no longer have any ownership interest in Luna i-Monitoring. However, we are entitled to receive payments under a Share Purchase and Asset Transfer Agreement with IHS Energy in connection with future product sales through November 2008. This agreement provides, among other things, that we are entitled to receive up to $2.5 million in payments based on a percentage of Luna i-Monitoring’s sales. We have not received any payments to date under this agreement and based on historical sales to date, we do not anticipate that the amounts, if any, we may receive in the future from Luna i-Monitoring will be material to our business.

Our Growth Strategy

We have the following key strategies to achieve our goal of accelerating the development and commercialization of innovative technologies and to create successful products in our areas of focus:

Transition our mix of revenues to a higher percentage of product and license revenues. We plan to commercialize a growing number of products in order to increase the amount of revenues that we generate from product sales and license payments. To this end, we will seek to expand our distribution network and our ability to service our customers. We will also seek to allocate resources to improve our ability to manufacture and shorten the cycle time from idea to market and to monetize our intellectual property portfolio by licensing our technologies. As a result, we believe that product sales and license revenues will comprise a greater portion of our total revenues in the future.

Business

Contract Research Group

Our Contract Research Group provides applied research to customers in our areas of focus – molecular technology solutions and sensing solutions. Our Contract Research Group competes to win contracts in these areas on a fee-for-service basis. This group has a successful track record of evaluating innovative technologies to address the needs of our customers. We identify these needs by utilizing our knowledge of the markets in our areas of focus and by consulting with major government entities, leading research universities and large corporations. We also use this network to obtain favorable technology transfer agreements, contract research revenues and strategic partnerships for the products that we develop based on our applied research.

We are working or have worked with over 60 corporate, academic and government collaborators, including:

Universities. The College of William and Mary, Duke University, Georgia Institute of Technology, North Dakota State University, The Ohio State University, The Pennsylvania State University, University of California, San Diego, University of Pittsburgh, University of Virginia, Washington University in St. Louis, University of Wyoming, and Virginia Polytechnic Institute and State University, or Virginia Tech;

Government entities. Defense Advanced Research Projects Agency, Defense Threat Reduction Agency, Environmental Protection Agency, National Aeronautics and Space Administration, National Institutes of Health, National Institute of Standards and Technology, National Science Foundation, United States Air Force, United States Army, United States Department of Agriculture, United States Department of Commerce, United States Department of Defense, United States Department of Energy, United States Department of Transportation and United States Navy; and

Corporations. Anteon International Corporation, Applied Research Associates, Inc., Dana Corporation and Northrop Grumman Corporation.

We seek to continue to maximize the benefits we derive from our contract research business, including revenue generation and identification of promising technologies for further development. For example, we proactively target selected projects with the highest commercialization potential. Also, we take a disciplined approach to contract research to ensure that in general the costs of any contract we undertake are fully covered. This approach enables us to cover the costs of riskier stage technology development with outside funding. We believe that this model is cost efficient and reduces our risk significantly.

As of March 31, 2006, our Contract Research Group was engaged in 68 separate active contracts that typically last from six months to three years. These projects span a wide range of applications across our areas of focus. The table below illustrates the type of research that these contracts encompass:


Competency/Platform Technology	Number of Contracts	Examples of Potential Products
Molecular Technology Solutions	30	Disease-targeting MRI contrast agents; flame retardants; coatings to shield devices from electromagnetic interference; multi-functional protective coating systems; and blast and ballistic resistant materials

Sensing Solutions	38	Medical diagnostic and monitoring instruments for heart and lung bypass operations, compartment syndrome and bone strength measurement; non-destructive industrial testing systems; and wireless remote and secure asset monitoring

Total	68

Business

Although we conduct our applied research on a fee-for-service basis for third parties, we seek to retain full or partial rights to the technologies and patents developed under those contracts and to continuously enlarge and strengthen our intellectual property portfolio. Often, a new technology that we develop complements existing technologies and enables us to develop applications and products that were not previously possible. In addition, the technologies we develop are often applicable to commercial markets beyond what was originally contemplated in the contract research of such technologies and we endeavor to capture the value of those opportunities.

As of March 31, 2006, our Contract Research Group team consisted of 90 people, 31 with Ph.D.s and 34 with advanced degrees. Our Contract Research Group also utilizes the knowledge and experience of researchers employed through the academic institutions, corporations and government agencies with which we subcontract. The Contract Research Group is organized into subgroups according to the area of technology, with each subgroup managed by its own director responsible for its financial performance. In addition, our Contract Research Group has in place disciplined processes designed to ensure quality control of proposal preparation, program reviews, pipeline reviews, revenues tracking and financial reporting.

Our Contract Research Group has a high historical success rate in winning bids for SBIR contracts, and we have won two National Tibbett’s Awards from the Small Business Administration for outstanding SBIR performance. SBIR contracts include Phase I feasibility contracts of up to $100 thousand and Phase II proof-of-concept contracts, which can be as high as $750 thousand. We also have been successful at winning contracts outside the SBIR program from corporations and government entities. Such contracts have no financial limit and typically have a longer duration, ranging from 12 to 24 months. As we continue to grow, one of our goals is to derive a larger portion of our contract research revenues from contracts outside the SBIR program.

Commercialization Strategy Group

Our Commercialization Strategy Group works with our Contract Research Group to identify technologies that have demonstrated proof of concept and that are ready for further development. After a detailed review, it is at this stage that we first consider investing our own funds to finance continued development. To this end, we have rigorous processes to evaluate the merits of further developing any given technology.

Initially, the Commercialization Strategy Group prepares proposals for selected high-potential proof-of-concept technologies for consideration by our internal investment committee. These proposals have the basic elements of a business plan, including detailed market, competitive, sales, marketing, distribution, financing and intellectual property analyses. Our internal investment committee, which is composed of key members of our management team and experts in the fields relevant to each opportunity, evaluates the merits of each proposal and makes recommendations to our management. Once qualified opportunities are approved by management, resources are allocated and the prototyping and development of a commercial product begins. During the product development process, the Commercialization Strategy Group and our internal investment committee regularly review progress and evaluate whether or not to allocate additional resources to, and to continue funding, development.

Our Commercialization Strategy Group includes personnel with a mix of intellectual property, technical and business backgrounds, including individuals who have experience with venture capital-backed companies and others who have successfully run major divisions of large corporations. In addition, we plan to consult with members of our advisory board with respect to product development matters from time to time. We believe that this combination of skills and experience is critical to the success of the product development process.

We have a successful track record, having developed more than a dozen products serving industries including energy, telecommunications, life sciences and defense. We believe our Commercialization Strategy Group is positioned to continue that success.

Business

Products Group

Overview

Our Products Group currently consists of the Luna Advanced Systems Division, the Luna nanoWorks Division and the Luna Technologies Division. We provide a description of these divisions below.

Luna Advanced Systems Division

The Luna Advanced Systems Division provides product development resources to a number of technologies and product candidates in transition from the Contract Research Group to a division within our Products Group. Although this division is currently offering some of our legacy products for commercial sale, we intend to build our capability to commercialize our existing innovative technologies. For example, to support our commercialization efforts, we have recently assembled a team of dedicated sales and marketing personnel with experience in industries related to our product candidates. Below we describe some of the products in our development pipeline.

Ultrasonic Technologies

We are developing a number of new devices that use high frequency sound, or ultrasonic, waves to evaluate the physical properties of materials. Application of ultrasonic technology in the medical field is commonly known as ultrasound. Our devices can determine the physical condition of an object by analyzing numerical measurements taken from ultrasonic waves that interact with the object. Our quantitative ultrasonic signal processing technology is designed to be extremely sensitive, detecting changes in the physical properties of the object studied. Our instruments report a numerical signature, not an image that is subject to interpretation and sometimes requires an expert consultant. Our technology thus provides information that cannot be obtained by traditional non-quantitative ultrasonic methodologies. Our quantitative ultrasonic technology has applications in medical diagnosis, non-destructive industrial testing and homeland security. All of our ultrasonic devices discussed below are currently in development stage and are not yet available for commercial sale. We have not yet submitted to the FDA any applications for clearance with respect to any of these devices.

Medical Monitoring and Diagnostic Devices

Ultrasound is an important, non-invasive tool for diagnosing disease inside the body. Roughly 700 thousand procedures utilizing ultrasound devices are performed each day worldwide. Our quantitative ultrasound supplements other diagnostic tools, providing a numerical readout of certain physical properties of the body part being analyzed, such as pressure or strain, which helps physicians diagnose certain disease conditions. We are developing medical device products with our ultrasound platform technology for the diagnosis of the following:

Compartment syndrome. Compartment syndrome is a buildup of pressure within muscles or other body parts following a severe traumatic blow. Such pressure buildup is often undetectable without surgery or other invasive procedures and the reduced blood flow from the disease can lead to debilitating injuries. QUS-1000CS is our compartment syndrome diagnostic device that is currently under development and is being designed to enable the doctors’ office or emergency room nursing staff to easily and consistently monitor this condition using a non-invasive method.

Bone strength. Bone loss due to osteoporosis is presently determined using x-ray techniques that measure the density of calcium in the bone. Our ultrasound technology measures the stiffness of the bone and can detect the difference between a bone bearing weight and one that is not. This measurement reflects the load bearing capacity, which is data that current devices in the market do not provide. QUS–1000BQ is our bone strength measurement device that is currently under development and is being designed to allow the monitoring of bone integrity and provide diagnostic information to improve the care of patients with osteoporosis.

Business

Intracranial pressure buildup. A heavy blow to the head can cause internal pressure that builds up rapidly and can cause morbidity and death if not treated. This condition is typically diagnosed by evaluating a patient’s response to external stimuli, which is not possible if the patient is unconscious. Our ultrasound technology can detect such pressure buildup rapidly in non-responsive patients by using a non-invasive device that reports a numerical readout and that does not require expert interpretation. QUS-1000ICP is our intracranial pressure measurement device that is currently under development and is being designed to enable trauma personnel to diagnose and monitor such a condition.

All three products, the QUS-1000CS, the QUS-1000BQ and the QUS-1000ICP, share common components, but also have customized interfaces specific to each application. The pathway to market for medical diagnostic devices requires approval by government agencies. For example, we will be required to obtain certification for safety through international standards as well as approval from the FDA through a 510(k) registration which we do not anticipate before the end of 2007. We are currently developing our marketing and distribution strategy for these products and have not yet submitted to the FDA any applications for clearance with respect to any of these products.

Non-Destructive Industrial Testing and Homeland Security Applications

We are developing a multi-purpose diagnostic instrument for the United States Army’s initiative to improve field service for deployed vehicles. Our multi-purpose diagnostic device measures the physical integrity of parts in the field based on their responses to an ultrasonic probe. Each part has its own distinct acoustic response to an ultrasonic probe which our device can read. A response falling outside a specified range indicates the part will not perform as required. Our device can test the integrity of a large number of replaceable vehicle parts having various uses and made of various materials. Other potential markets for this product include materials laboratories and manufacturing quality assurance departments.

We are also developing homeland security products based on our ultrasonic platform technology, such as an ultrasonic wand to detect weapons concealed beneath clothing and a product that identifies vehicles on the highway system that might be transporting weapons of mass destruction. We plan to continue to develop these homeland security products through our Contract Research Division until we have completed prototype testing, which we anticipate will take at least one year. We intend to market these products, should they prove viable, to government entities and corporations.

Remote and Secure Asset Monitoring

We are developing innovative applications integrating sensors, software and hardware components to provide remote and secure asset monitoring solutions and products. These products, which are currently in development and are not yet available for commercial sale, integrate several technologies such as:

Sensors utilizing light-transmitting optical fibers, or fiber optic sensors, that collect vital information, such as temperature, pressure, strain, movement, moisture, sound or other changes where they are deployed. We have particular experience developing sensors that operate in harsh environments.

Encryption technology that scrambles wireless communications to provide security for military or industrial uses. We are designing a card that plugs into the network slot of a laptop or other portable wireless device and serves as a receptacle for any standard network card, converting the wireless communication into a secure, encrypted transmission that can only be unscrambled by a receiver with a similar card.

Wireless transmission technology to send the data from remote sensors to a central monitoring station, enabling a customer to maintain real time, sensitive contact information about the health of machinery, or other equipment without the expense and inconvenience of installing cable-connected sensors.

Secure wireless technology that encrypts the data from wireless sensors prior to transmission for settings where the customer needs security.

Business

We are developing cost-effective remote and secure asset monitoring products that are simple to install and that offer industrial customers the ability to gather data critical to the performance of their equipment and to increase the reliability and performance of their machinery. These sensors are designed to work in harsh environments or in difficult to reach sites to monitor critical data, such as temperature, pressure and a number of other variables.

We also are developing products for military secure wireless communication applications. For example, we are working with the U.S. Navy to enable handheld wireless devices to communicate securely with a ship or submarine network. In addition, we are developing a sophisticated system that is designed to detect security breaches.

Flame Retardants

We are developing proprietary flame retardants that can be mixed with other components into fire resistant composites or spray-on coatings for textiles. Originally developed to provide the U.S. Navy with fire resistant ammunition packages, our flame retardant produces a non-combustible surface under fire condition and slows heat transfer through the material. Unlike many flame retardants used today, we believe that our product is environmentally sound in both its manufacture and disposal and that it does not produce toxic fumes if it eventually burns. We plan to collaborate with a leading manufacturer and marketer of textile products to continue development of our flame retardant coating technology.

Multi-Functional Protective Coating Systems

We are developing a family of multi-functional protective coating products to meet numerous market opportunities. Our approach involves the combination of innovative resin systems with commercially available and proprietary additives to create high performance primers and topcoats. Our engineered coating systems are designed to have a variety of key performance attributes, including anti-corrosion, self-healing, rapid cure, non-skid, and tailored dielectric properties. In addition to coatings, we are also developing other complementary products, such as surface cleaners and pretreatments that will improve the performance of the entire coating system. We plan to engage with large coatings manufacturers for the eventual production and distribution of our coating systems through established channels.

Blast and Ballistic Resistant Materials

We are developing a variety of blast and ballistic resistant coatings, materials and composites for critical defense and homeland security applications. We combine resins, polymers, fibers, fabrics and composites that we have developed with commercially-available components to create high strength, lightweight and flexible materials that range in application from soldiers to ships. Specific examples of potential applications include a new ammunition packaging system to protect both ordnance and soldiers; a flexible blast resistant polymer to improve the integrity of ship deck coating systems and to prevent interior shrapnel in the event of an explosive blast; and lightweight, transparent, ballistic resistant polymers for use in next generation military visors.

Luna nanoWorks Division

Overview

Our Luna nanoWorks Division is developing advanced carbon nanomaterials, which are molecular structures consisting of carbon atoms in distinctive geometric shapes. Advanced carbon nanomaterials include: Trimetasphere™ nanomaterials, a new class of materials that we describe in more detail below; fullerenes, which are carbon spheres that resemble a soccer ball; and carbon nanotubes, which are carbon rings shaped like a cylinder.

A Trimetasphere™ nanomaterial is a carbon sphere with three metal atoms enclosed inside. Using different combinations of a group of 17 rare earth metals, we can develop thousands of different types of Trimetasphere™ nanomaterials, each with distinctive properties and performance characteristics and each potentially marketable as a separate product. We recently were awarded the Nano 50 Products Award by NASA’s Tech Briefs publication for our Trimetasphere™ nanomaterials.

Business

Through our collaborative relationship with Virginia Tech, we have obtained an exclusive license to commercialize Trimetasphere™ nanomaterials under an issued U.S. patent and pending U.S. applications. Each type of Trimetasphere™ nanomaterial has distinctive chemical, physical or biological properties due to the properties of the metals enclosed in its carbon cage. We can further customize Trimetasphere™ nanomaterials for specific applications by attaching different atoms or molecules to the surface of their carbon spheres. In some cases, the knowledge we gain from customizing Trimetasphere™ nanomaterials for specific applications may provide us with new intellectual property covering Trimetasphere™ nanomaterials and may also provide us with new intellectual property covering carbon nanomaterials other than Trimetasphere™ nanomaterials, further expanding our inventory of potential new products.

We currently manufacture carbon nanotubes based on intellectual property we have developed and licensed. As we continue to improve this technology and identify new applications, we intend to seek additional intellectual property protections for such improvements to this technology.

We have won a number of government contracts funding new applications of nanotechnology totaling approximately $11.0 million. These contracts are partially funding our development of manufacturing processes to produce nanomaterials in large

quantities. Furthermore, we are researching and developing new applications exploring the physical properties of nanomaterials. As of March 31, 2006, we had invested nearly $3.1 million of our own funds in these activities and we plan to continue to compete for additional research contracts to support our Luna nanoWorks Division.

Our Luna nanoWorks Division will focus on business opportunities in which we are well-positioned to have a strong intellectual property position in the United States and for which our products are likely to command premium pricing. We believe these opportunities exist in materials supply and medical applications. Our Luna nanoWorks Division plans to supply advanced carbon nanomaterials to customers in different industries where our nanomaterials will enable and become components of our customers’ products. Our Luna nanoWorks Division is also identifying medical application products utilizing Trimetasphere™ nanomaterials.

Medical Imaging

Magnetic resonance imaging, or MRI, has been established as the imaging technology of choice for a broad range of applications, including the identification and diagnosis of a variety of medical disorders. MRI provides three-dimensional images that enable physicians to diagnose and manage disease in a minimally invasive manner. MRI contrast agents, used in about 30% of MRI procedures, improve the resolution of MRI images by enhancing the contrast in the organ or tissue in the body where the contrast agent circulates. Most of the contrast agents approved by the FDA use gadolinium, a toxic metal. To neutralize gadolinium’s toxicity, contrast agents use organic compounds called chelates that wrap around the gadolinium, shielding the patient from its toxicity. However, chelates cannot neutralize the gadolinium if it escapes into the bloodstream. Hence, the longer the agent circulates, the greater the risk of toxicity. As a result, the contrast agents currently in use need to be eliminated from the body quickly, making it difficult to produce high quality images.

Our Luna nanoWorks Division is developing a Trimetasphere™ nanomaterial-based MRI contrast agent. We believe our Trimetasphere™ nanomaterial-based contrast agent offers two potential advantages: lower risk of toxicity and higher image contrast. Due to the strength of the Trimetasphere™ nanomaterial’s carbon cage enclosing the gadolinium, our Trimetasphere™ nanomaterial-based contrast agent can neutralize gadolinium for a longer period of time, and therefore allow the contrast agent to remain safely in the body longer. Experiments have also shown that Trimetasphere™ nanomaterials provide a stronger contrast effect than the other contrast agents currently on the market. The first compound in this program is in preclinical development, with an investigational new drug application, or IND, planned for the end of 2006.

In addition, we are developing various modifications to the Trimetasphere™ nanomaterials to target them for specific tissues or physiological conditions. We believe that, using the Trimetasphere™ nanomaterials, a complete family of disease-targeting diagnostic agents can be created to enhance the capabilities of MRI imaging and significantly expand its applications.

Medical contrast agents for human use must be approved by the FDA or similar foreign regulatory agencies before they can be marketed, which we do not expect before 2009. We are in the early stages of developing a marketing strategy for our MRI contrast agent.

Business

Materials Supply Business

Our Luna nanoWorks Division has two goals for its materials supply business: to identify new product opportunities by supplying carbon nanomaterials to research laboratories in academia, government and industry; and to develop customized products with specialized performance characteristics for use in industrial applications.

Luna nanoWorks sells carbon nanomaterial kits to academic, federal and private laboratories. These kits are sold to dedicated researchers with the objective of encouraging the discovery of new applications such as nano-scale circuit components, memory storage devices and biological tracers. Should these researchers discover an important new use, we expect that our proprietary position surrounding the relevant material will position us to negotiate favorable terms with the inventors of such new use.

We also have active research programs investigating the enhancement of various industrial materials, including:

High performance solar panels. Solar panels are designed to capture light and convert its energy into electrical power. Solar panels currently on the market face limitations in efficiently converting solar energy into electrical power. We are in the early stages of developing a product that uses the electrical properties of Trimetasphere™ nanomaterials to increase the overall efficiency of solar panels.

Stronger and lighter composites. Composite structures utilizing polymers, which are materials made up of smaller, linked building blocks, have replaced many metal structures for use in military body and vehicle armor due to their greater strength and lighter weight. We are investigating new technologies to further reduce the weight and enhance the strength of these composites including enhancements to the existing carbon nanotubes that we currently manufacture.

Coatings to shield devices from electromagnetic interference. Carbon nanomaterials provide the strength of carbon fibers and are lightweight and highly conductive, making them suitable for use in coatings designed to shield electronics and electrical equipment from radio waves.

Luna Technologies Division

We reacquired Luna Technologies, Inc. in September 2005, and currently operate it as our Luna Technologies Division. We established Luna Technologies, Inc. in July 1998 and funded its growth by raising venture capital. Such financing activities diluted our equity ownership to as little as approximately 7% during our holding period and to approximately 10% prior to September 2005. In line with our strategy of building a growing portfolio of products, we purchased all of the stock of Luna Technologies, Inc. that we did not own in exchange for shares of our common stock in September 2005. Our acquisition of Luna Technologies is expected to enhance our development and production of fiber-optic technology.

Test and Measurement Equipment

Our test and measurement products monitor the integrity of fiber optic network components and subassemblies. Luna Technologies Division’s products are designed for manufacturers and suppliers of optical components and sub-assemblies and allow them to reduce costs and improve the quality of their products. Most manufacturers and suppliers of optical components and modules currently use a combination of different types of optical test equipment to identify and measure failures in optical networks, such as bad splices, bends, crimps and other reflective and non-reflective events. Our optical test equipment products replace the need for these multiple test products and address all stages of the end user’s product development life cycle including: design verification, component qualification, assembly process verification and failure analysis.

Our Luna Technologies Division has two flagship product lines—our Optical Vector Analyzer, or OVA, and our Optical Backscattering Reflectometer, or OBR. Our award winning OVA platform allows manufacturers and suppliers of optical components and sub-assemblies to reduce costs and time-to-market by replacing multiple, time consuming and expensive measurement platforms with a single, integrated and easy-to-use instrument. Our most recent version of OVA operating

Business

software provides customers with faster testing times, advanced data analysis options and an extended dynamic range relative to previous versions.

Our OBR is a highly sensitive diagnostic device that allows data and telecommunications companies and the service providers who maintain their own fiber optic networks to reduce test time and improve product quality. Our OBR introduces the ability to inspect metropolitan fiber networks with higher resolution and better sensitivity than previously possible. Its user-friendly graphical user interface also makes the OBR product suitable for both research and manufacturing applications.

We expect to increase sales of our optical test equipment products by expanding our customer base beyond the telecommunications industry into avionics, defense and academic research laboratories.

In 2005, Luna Technologies Division received the Frost & Sullivan “Award for Product Line Strategy” for its OVA product and the Frost & Sullivan “Optical Product of the Year Award” for its OBR product.

In June 2005, Luna Technologies entered into a Joint Cooperation Agreement with Luna Energy. Under this agreement, both parties have agreed to cooperate to develop a fiber optic sensing system product and have agreed to contribute materials, intellectual property, personnel and other resources to the development effort. Upon successful completion of product development, Luna Energy will receive a license to certain of Luna Technologies’ intellectual property and will be required beginning in 2007 and continuing through December 31, 2017 to make payments to Luna Technologies with respect to revenues derived from products sold that utilize this intellectual property. Although as of March 31, 2006, Luna Energy had not yet sold products that would entitle Luna Technologies to royalty payments under this joint cooperation agreement, Luna Technologies had received aggregate development milestone payments of $305 thousand as of that date under this agreement and is entitled to receive additional development milestone payments of $120 thousand in the aggregate, subject to the satisfaction of certain conditions. Luna Technologies also has the right to receive royalty payments from sales of products in the future. The license of certain of the intellectual property from Luna Technologies to Luna Energy shall be an exclusive license if Luna Energy makes certain minimum royalty payments of $420 thousand in the aggregate between 2007 and 2017, and shall be a non-exclusive license if Luna Energy fails to make these minimum royalty payments. Either party has the right to terminate this agreement during the development term (which, unless extended by mutual agreement of the parties, will expire June 6, 2006) upon a provision of advance written notice to the other party. However, if either party terminates the agreement for convenience or failure to meet certain development milestones, the terminating party may be required to grant license rights to the non-terminating party, including, where Luna Technologies is the terminating party, certain non-exclusive and certain exclusive rights with respect to intellectual property of Luna Technologies required to complete the development effort, and where Luna Energy is the terminating party, non-exclusive commercialization rights with respect to certain intellectual property of Luna Energy. Since December 2004, we have not held an ownership interest in Luna Energy. Luna Technologies continues to operate as our Luna Technologies Division after we acquired that entity in September 2005.

Integrated Sensing Solutions

We have significant knowledge and experience in Distributed Sensing Systems, or DSS, which are products comprised of multiple sensors whose input is integrated through a fiber optic network and software. Our DSS products use fiber optic sensing technology with an innovative monitoring system that allows several thousand sensors to be networked along a single optical fiber. Some key applications, markets and technical advantages of our DSS are described below.

Distributed Strain. Potential markets for our DSS products include the airframe industry, integrated structural monitoring on civil structures and space applications. For example, a major air frame manufacturer deployed our DSS products during fatigue tests to measure strain through a network of sensors distributed throughout an aircraft. Our distributed strain measurement technology can also provide three-dimensional shape measurement. We are developing this technology for use in robotic tethers and for wing structures. We have sold our shape-sensing probes to a major aircraft manufacturer for measuring shape on an aerodynamic surface.

Business

Distributed Temperature. We sell a network of distributed temperature sensors to a major manufacturer of electrical generators. This DSS product enables the direct monitoring of temperature, which helps to prolong generator life and to increase operational efficiency. We have also sold our DSS temperature sensors to NASA for both ultra-cold and extremely high-temperature measurements. Potential markets include industrial process control and electrical system monitoring.

Competition

We compete for government, university and corporate research contracts relating to a broad range of technologies. We also compete in the materials supply sensing and fiber optic network testing markets. In addition, we plan to develop and commercialize multiple molecular technology and sensing solutions products across many industries, technologies and markets. As a result, we compete, or will compete, with a variety of companies in several different markets.

Competition for contract research is intense and the industry has few barriers to entry. We compete against a number of in-house research and development departments of major corporations, as well as a number of small, limited-service contract research providers. The contract research industry continues to experience consolidation, which has resulted in greater competition for clients. Increased competition might lead to price and other forms of competition that could harm our operating results.

We compete for contract research on the basis of a number of factors, including reliability, past performance, expertise and experience in specific areas, scope of service offerings, technological capabilities and price. Although there can be no assurance that we will continue to do so, we believe that we compete favorably in these areas. If in the future we are unable to effectively compete in these areas, we could lose business to our competitors, which could harm our operating results. Our competitors in contract research include, but are not limited to, companies such as General Dynamics Corporation, Lockheed Martin Corporation, SAIC, Inc. and SRA International, Inc.

In the molecular technology solutions products market, our competitors include, but are not limited to, large public manufacturers such as The Dow Chemical Company, E.I. du Pont de Nemours and Company, Rohm and Haas Company and 3M Company, as well as emerging advanced materials companies.

In addition, in the MRI contrast agent market, our competitors include Amersham plc, Berlex Laboratories, Inc., Bracco Diagnostics, Inc. and Mallinckrodt Inc.

In the sensor solutions products market, our competitors include, but are not limited to, large companies such as Agilent Technologies, Inc., Analog Devices, Inc., Freescale Semiconductor, Inc., JDS Uniphase Corp., Robert Bosch GmbH and Silicon Sensing, as well as emerging companies developing innovative sensing technologies.

The products that we have developed or are currently developing will compete with other technologically innovative products, as well as products incorporating conventional materials and technologies. We expect that our products will compete with companies in a wide range of industries, including semiconductors, electronics, biotechnology, textiles, alternative energy, military, defense, healthcare, telecommunications, industrial measurement, security applications and consumer electronics.

Intellectual Property

We seek patent protection on inventions that we consider important to the development of our business. We rely on a combination of patent, trademark, copyright and trade secret laws in the United States and other jurisdictions, as well as confidentiality procedures and contractual provisions to protect our proprietary technology and our brand. We control access to our proprietary technology and enter into confidentiality and invention assignment agreements with our employees and consultants and confidentiality agreements with other third parties.

Our success depends in part on our ability to develop patentable products and obtain, maintain and enforce patent and trade secret protection for our products, as well as successfully defend these patents against third party challenges both in the United States and in other countries. We will only be able to protect our technologies from unauthorized use by third parties to

Business

the extent that we own or have licensed valid and enforceable patents or trade secrets that cover them. Furthermore, the degree of future protection of our proprietary rights is uncertain because legal means afford only limited protection and may not adequately protect our rights or permit us to gain or keep our competitive advantage.

Currently, we own or license numerous U.S. patents and patent applications, and we intend to file, or request that our licensors file, additional patent applications for patents covering our products. However, patents may not be issued for any pending or future pending patent applications owned by or licensed to us. Claims allowed under any issued patent or future issued patent owned or licensed by us may not be valid or sufficiently broad to protect our technologies. Any issued patents owned by or licensed to us now or in the future may be challenged, invalidated or circumvented, and, in addition, the rights under such patents may not provide us with competitive advantages. In addition, competitors may design around our technology or develop competing technologies. Intellectual property rights may also be unavailable or limited in some foreign countries, which could make it easier for competitors to capture or increase their market share with respect to related technologies. Although we are not currently involved in any legal proceedings related to intellectual property, we could incur substantial costs to defend ourselves in suits brought against us or in suits in which we may assert our patent rights against others. An unfavorable outcome of any such litigation could have a material adverse effect on our business and results of operations.

As of March 31, 2006, we owned or had exclusive rights to use at least 39 issued U.S. patents and at least 63 additional pending U.S., international and foreign patent applications. As of March 31, 2006, we did not have any issued or granted foreign patents. In particular, as of March 31, 2006, we owned or had exclusive license to the following issued patents and applications as they relate to specific products:

two issued U.S. patents with expiration dates ranging from December 2021 to April 2024, three pending U.S. patent applications, and two pending foreign patent applications relating to our OVA and OBR products;

four issued U.S. patents with expiration dates ranging from August 2019 to August 2021, six pending U.S. patent applications, and 11 pending foreign patent applications relating to our carbon nanomaterials, including Trimetasphere™ nanomaterials;

three pending U.S. patent applications and one pending foreign patent application relating to our DSS technology;

11 issued U.S. patents with expiration dates ranging from June 2011 to September 2022, three pending U.S. patent applications and two pending foreign patent application relating to our ultrasound technologies for medical applications;

one issued U.S. patent expiring April 2024, two pending U.S. patent applications and three pending foreign applications relating to our ultrasonic technologies for weapons detection and non-destructive industrial testing technologies;

five issued U.S. patents with expiration dates ranging from February 2012 to April 2020, and three pending U.S. patent applications and one pending foreign patent applications relating to our remote and secure asset monitoring technologies;

two issued U.S. patents expiring April 1, 2024, four pending U.S. patent applications and seven pending foreign patent applications relating to our flame retardant, impact indicator coatings and multifunctional protective coatings; and

14 issued U.S. patents with expiration dates ranging from February 2016 to March 2024, and 12 pending U.S. and foreign patent applications relating to our various other technologies.

We own 25 of the issued U.S. patents, 22 of the U.S. patent applications and 26 of the foreign patent applications identified above. The remaining 14 issued U.S. patents, seven U.S. patent applications and eight foreign patent applications are owned by and licensed exclusively from third parties, which include educational institutions, government agencies and for-profit

Business

companies. We consider the following exclusive license agreements to be material to our business:

Virginia Tech nanomaterials license. Our Amended and Restated License Agreement with Virginia Tech Intellectual Properties, Inc., or VTIP, dated March 19, 2004, relating to Trimetasphere™ nanomaterials, which provides us with rights to one issued U.S. patent, one U.S. patent application and one foreign patent application. Under this license agreement, VTIP granted us an exclusive worldwide license, in all fields of use, under the foregoing patent rights, to make, have made, use and sell licensed products, with a reservation of rights by VTIP for educational and research purposes. We are required to diligently pursue development, manufacture and sale of licensed products, and are also required to, among other things, raise financing before March 19, 2009, make annual expenditures of $100 thousand per year through March 2009 toward development of the licensed products, use reasonable efforts to market the licensed products and meet market demand, and distribute research samples of the licensed products. If we fail to do so, VTIP has the right to terminate the license or to change the exclusive license to a non-exclusive license. We paid up-front fees for this license agreement and are required to pay to VTIP royalties on product sales, including royalties on product sales by companies to which we have granted a sublicense. We are also required to pay VTIP $225 thousand in the aggregate upon the achievement of certain milestones. We have made aggregate payments of $38 thousand through March 31, 2006 under this agreement, representing payment of upfront fees, and have also spent over $200 thousand toward development of licensed products to date as required by the license agreement. Our licensed products sold in the United States must be manufactured substantially in the United States. The license expires upon the expiration of the last licensed patent set forth in the license agreement, and our remaining milestone and minimum royalty payment obligations through that date are $225 thousand in the aggregate. We have the right to terminate the license agreement for convenience, and VTIP has the right to terminate the agreement upon a material breach by us or our failure to make a payment. We agreed to indemnify VTIP against any claims arising out of our exercise of the license granted or any sublicense, including for products liability claims. VTIP is responsible for diligently pursuing the prosecution and maintenance of the patents at issue, and must consult with us and provide us with a reasonable opportunity to review and comment on all proposed submissions to any patent office. VTIP has the first right to institute an action for infringement of the licensed intellectual property; we can bring an infringement claim against third parties only if VTIP elects not to. Recoveries from any such action belong to the party bringing suit. If legal actions are brought jointly by VTIP and us where we each fully participate in such action, the recoveries are shared in jointly in proportion to the share of expense paid by each party.

NASA ultrasound technologies license. Our License Agreement No. DE-384 with NASA dated October 28, 2004, relating to ultrasound technologies, which provides us with rights to 10 issued U.S. patents, two U.S. patent applications and one foreign patent application. Under this license agreement, NASA granted us a terminable, exclusive license to make, have made, use and sell licensed inventions, in the United States (including its territories and possessions) and other jurisdictions that are covered by a patent or patent application, in the field of medical applications for assessing and measuring intracranial pressure and compartment syndrome. We are required to achieve practical application, which is generally defined as a commercial application or use for which a market exists, of the licensed application before September 7, 2006, and achieve certain milestones along the way. We paid up-front fees for this license agreement and are required to pay to NASA and to the University of California, a joint owner with NASA of one of the patent applications covered by the license agreement, royalties on product sales, including minimum annual royalties from 2004 through the term of the license agreement as well as royalties on product sales by companies to which we have granted a sublicense. We have made aggregate payments of five thousand dollars through March 31, 2006 under this agreement. Our products under this license must be manufactured substantially in the United States. The license expires upon the expiration of the last licensed patent set forth in the license agreement, and our minimum annual royalty payments and fees from January 1, 2006 through that date are $235 thousand in the aggregate. We may terminate the license agreement with advance notice or immediately upon a material breach by NASA. NASA may terminate the license upon a material breach by us or if NASA determines, among other things, that (i) we have failed to achieve or maintain practical application of the

Business

licensed invention before September 7, 2006, (ii) we have not substantially manufactured the licensed invention in the United States, or (iii) we have failed to meet market demand, to pay royalties or to submit required reports. In addition, until September 7, 2009, NASA is permitted to unilaterally modify or revoke the license as to any licensed invention for which we have not achieved a practical application. We agreed to indemnify NASA and the University of California against claims arising out of our use of the licensed invention or our sale, use or disposition of products or processes made by use of such inventions. We have the right to enforce the licensed patents, subject to the U.S. government’s right to bring suit or intervene, and any recoveries must be shared with NASA and the University of California on terms to be negotiated with them.

In addition to the exclusive license agreements described above, we consider the following non-exclusive license agreements to be material to our business because they relate to certain of our key products:

NASA OVA and OBR products and DSS technology licenses. Our License Agreement with NASA No. DN-982 dated June 10, 2002, as modified on dated January 23, 2006, and our License Agreement with NASA No. DN-951 dated December 20, 2000, relating to our OVA and OBR products and DSS technology, which provide us with rights to four issued U.S. patents and two foreign patent applications. Under these license agreements, NASA granted us a terminable, non-exclusive license to make, have made, use and sell licensed inventions, in the United States (including its territories and possessions), in all fields of use. We paid up-front fees for this license agreement and are required to pay royalties on product sales, including minimum annual royalties from 2003 through the term of the license agreement as well as royalties on product sales by, and other payments we receive from, companies to which we have granted a sublicense. We have made aggregate payments of $350 thousand through March 31, 2006 under this agreement. Our products under this license must be manufactured substantially in the United States. The license expires upon the expiration of the last licensed patent set forth in the license agreement, and our minimum annual royalty payments from January 1, 2006 through that date are $3.5 million in the aggregate. We may terminate the license agreement with advance notice or immediately upon a material breach by NASA. NASA may terminate the license upon a material breach by us or if NASA determines, among other things, that (i) we failed to achieve or maintain practical application of the licensed invention before June 10, 2004, (ii) we have not substantially manufactured the licensed invention in the United States, or (iii) we have failed to meet market demand, to pay royalties or to submit required reports. In addition, NASA is permitted to unilaterally modify or terminate the agreement in event of a breach by us by providing notice to us and allowing us to challenge or protest its decision. We agreed to indemnify NASA against claims arising out of our use of the licensed invention or information provided by NASA, or our sale, use or disposition of products or processes made by use of such inventions or such information. We have the right to enforce the licensed patents, subject to the U.S. government’s right to bring suit or intervene, and any recoveries must be shared with NASA on terms to be negotiated with them.

United Technologies Corporation DSS technology license. Our Fiber Optic Patent License with United Technologies Corporation, or UTC, dated September 22, 2003, relating to DSS technology, which provides us with rights to two issued U.S. patents. Under this license agreement, UTC granted us a non-exclusive, non-transferable, worldwide license, under the foregoing patent rights, to make, have made, use and sell licensed products, without the right to grant sublicenses. We paid non-refundable up-front fees for this license agreement and are required to pay royalties on product sales. We have made aggregate payments of $51 thousand through March 31, 2006 under this agreement. The license expires upon the expiration of the patent licensed that has the longest life unless earlier terminated. We do not have the right to terminate the license agreement without the agreement of UTC, but UTC has the right to terminate upon, among other things, a material breach by us or our failure to make a payment. We agreed to indemnify UTC against any claims relating to (i) use of the licensed patents by us, our customers, subcontractors, agents or employees, and (ii) our manufacture, use and sale of the licensed products. UTC may decide in its sole discretion whether to enforce its rights under the licensed patents or to defend any action with respect to such patents. Any such action would be under UTC’s sole control and at its expense, and UTC would retain all damages and recoveries from any such action.

Business

We may not be able to prevent third parties from obtaining rights from our licensor that are identical to ours. For example, because our licenses from NASA and UTC described above that relate to fiber Bragg grating and fiber optic strain sensing are non-exclusive, others, including our competitors, may obtain rights from our licensor that are identical to ours.

The development of some of our intellectual property, including software, may have been funded by the U.S. government including under, or in connection with, U.S. government contracts and other federal agreements. Similarly, some of our patents may cover inventions that were conceived or first reduced to actual practice under, or in connection with, U.S. government contracts or other federal funding agreements. The U.S. government may constrain the use of intellectual property, including patents and software that was developed through or under U.S. government contracts, federal funding agreements or other federal agreements. In addition, in instances where the U.S. government has provided funding of, or for, the development of intellectual property, the U.S. government typically retains a non-exclusive, royalty-free, world-wide license to use the intellectual property in any manner it deems appropriate including, in some specific circumstances, providing it to our competitors. When we work on U.S. government contracts, federal funding agreements and other federal instruments, we seek to protect our proprietary technologies and intellectual property developed at private expense by taking steps to maintain ownership of such intellectual property, as well as steps intended to limit the U.S. government’s rights in such intellectual property to the extent permitted by applicable statutes, rules and regulations. We may not have succeeded in our efforts to maintain title in patents or ownership or in limiting the U.S. government’s rights in our proprietary technologies and the intellectual property whether developed in the performance of a federal funding agreement or developed at private expense.

In addition to patent and trade secret protection, we also rely on several registered and unregistered trademarks to protect our brand. LUNA INNOVATIONS is a registered trademark in the United States. Our unregistered trademarks include: our logo (a black and white image of a moth design); TRIMETASPHERES; EDAC; APHROTROPHIN, AMANUET, SECURING SILICON and SOFTWARE and THE AMANUET ARCHITECTURE.

Our intellectual property policy is to protect our products, technology and processes by asserting our intellectual property rights where appropriate and prudent. However, we currently have no foreign issued patents and only three pending foreign applications in the field of endohedral metallofullerenes, and any pending or future pending patent applications owned by or licensed to us (in the United States or abroad) may not be allowed or may in the future be challenged, invalidated or circumvented, and the rights under such patents may not provide us with competitive advantages. Any significant impairment of our intellectual property rights could harm our business or our ability to compete. Protecting our intellectual property rights is costly and time consuming. Any increase in the unauthorized use of our intellectual property could make it more expensive to do business and harm our operating results.

There is always the risk that third parties may claim that we are infringing upon their intellectual property rights and, if successful in proving such claims, we could be prevented from selling our products or services. For example, we are aware of competitors with patents in technology areas applicable to our optical test equipment products. Such competitors may allege that we infringe these patents. In addition, we acquired a business that had received a letter in 2002 from a competitor alleging infringement of certain patents. The competitor sent an additional letter on January 14, 2004 to the business that we acquired, again alleging infringement of the competitor’s patents. Neither we nor the business that we acquired have received any further communications from this third party. We cannot currently predict whether this third party, or any other third party, will assert a claim against us, or whether any third parties that have asserted such claims against businesses that we have acquired will assert claims or pursue infringement litigation against us; nor can we predict the ultimate outcome of any such potential claims or litigation.

Even if such claims are unfounded, we could suffer significant litigation or licensing expenses as a result of such claims. Companies in the molecular technology solutions, advanced materials, nanotechnology, systems integration, sensing and fiber optics industries own numerous patents, copyrights and trademarks and frequently enter into litigation based on allegations of infringement or other violations of intellectual property rights. As we face increasing competition, the possibility of intellectual property claims against us grows. Our technologies may not be able to withstand any third-party claims or rights against their use.

Business

In recent years, numerous patent applications have been filed by others with the United States Patent and Trademark Office that refer to molecular technology solutions, advanced materials, nanotechnology, systems integration, sensing, fiber optics and our other core technologies. Information contained in patent applications is generally not publicly available. Consequently, we are unable to evaluate the underlying intellectual property until these patent applications become issued or published. The process to issue patents is long and certain innovations that have not yet resulted in issued patents could have been developed prior to our intellectual property. These patents, if and when issued, may predate our patents and may have superior claims or superior rights or otherwise be in conflict with our technology or business processes.

For additional, important information related to our intellectual property, please review the information set forth in “Risk factors—Risks Related to Our Business and Technologies.”

Government Regulation

Small Business Innovation Research Qualifications

We presently benefit from our status as qualifying for the U.S. Government’s Small Business Innovation Research, or SBIR, program administered by the U.S. Small Business Administration, or SBA. SBIR is a highly competitive program that encourages small businesses to explore their technological potential and provides them incentive to profit from the commercialization of technologies. Each year, ten federal agencies and departments, including NASA, the Department of Defense and the National Institutes of Health, are required to set aside a portion of their grant awards for SBIR-qualified organizations. SBIR contracts include Phase I feasibility contracts of up to $100 thousand and Phase II proof-of-concept contracts, which can be as high as $750 thousand. Several of our research contracts have used this program as a key source of project funding to develop new technologies.

We must continue to qualify for the SBIR program in order to be eligible to receive future SBIR awards. The eligibility requirements are:

Ownership. The company must be at least 51 percent owned and controlled by U.S. citizens or permanent resident aliens, or owned by an entity that is itself at least 51 percent owned and controlled by U.S. citizens or permanent resident aliens; and

Size. The company, including its affiliates, cannot have more than 500 employees.

These requirements are set forth in the SBA’s regulations and are interpreted by the SBA’s Office of Hearings and Appeals. In determining whether we satisfy the 51% equity ownership requirement, agreements to merge, stock options, convertible debt and other similar instruments are given “present effect” by the SBA as though the underlying security were actually issued unless the exercisability or conversion of such securities is speculative, remote or beyond the control of the security holder. We therefore believe our outstanding options and warrants held by eligible individuals may be counted as outstanding equity for purposes of meeting the 51% equity ownership requirement. As of March 31, 2006, giving present effect to our outstanding options, at least approximately 76% of our equity was owned by U.S. citizens or permanent residents. Upon the completion of this offering, at least approximately 59% of our equity will be owned by U.S. citizens or permanent residents (and at least approximately 57% assuming exercise of the underwriters’ over-allotment option). In addition, to be eligible for SBIR contracts, the number of our employees, including those of any entities that are considered to be affiliated with us, cannot exceed 500. As of March 31, 2006, we, including all of our divisions, had 148 full-time and 13 part-time employees. In determining whether we have 500 or fewer employees, the SBA may count the number of employees of entities that are large stockholders who are “affiliated”, or have the power to control us. In determining whether two or more firms are affiliated, the SBA will look at indicia such as stock ownership or common management, but ultimately will make its determination based on the “totality of the circumstances.” The SBA presumes that a large stockholder of ours has the power to control us absent evidence rebutting that presumption. With respect to Carilion Health System, our only large institutional stockholder, we believe we would not be required to count the employees of Carilion Health System. We believe the relative beneficial

Business

ownership of our individual stockholders rebuts the presumption of control by Carilion Health System because the shares held by our executive officers and directors constitute the controlling voting interest in us. Eligibility protests can be raised to the SBA by a competitor or by the awarding contracting agency. Accordingly, a company can be declared ineligible for a contract award as a result of a competitor’s protest to the SBA or as a result of questioning by the awarding contracting agency. We believe that we are currently in compliance with the SBIR eligibility criteria, but we cannot provide assurance that the SBA will interpret its regulations in our favor. As we grow larger, and as our ownership becomes more diversified, we may no longer qualify for the SBIR program, and we may be required to seek alternative sources and partnerships to fund some of our research and development costs. See “Risk factors—Risks Related to Our Business and Technologies.”

Environmental

Our facilities and current and proposed activities involve the use of a broad range of materials that are considered hazardous under applicable laws and regulations. Accordingly, we are subject to a number of foreign and domestic laws and regulations relating to health and safety, protection of the environment, product labeling and product take back, and the storage, use, disposal of, and exposure to, hazardous materials and wastes. We could incur costs, fines and civil and criminal penalties, personal injury and third party property damage claims, or we could be required to incur substantial investigation or remediation costs if we were to violate or become liable under environmental, health and safety laws. Moreover, a failure to comply with environmental laws could result in fines and the revocation of environmental permits, which could prevent us from conducting our business. Liability under environmental laws can be joint and several and without regard to fault. There can be no assurance that violations of environmental health and safety laws will not occur in the future as a result of the inability to obtain permits, human error, equipment failure or other causes. Environmental laws could become more stringent over time, imposing greater compliance costs and increasing risks and penalties associated with violations, which could harm our business. Further, violations of present and future environmental laws could restrict our ability to expand facilities, pursue certain technologies, and could require us to acquire costly equipment, or to incur potentially significant costs to comply with environmental regulations.

The European Union Directive 2002/96/EC on Waste Electrical and Electronic Equipment, known as the “WEEE Directive,” requires producers of certain electrical and electronic equipment, including monitoring instruments, to be financially responsible for specified collection, recycling, treatment and disposal of past and present covered products placed on the market in the European Union. As a manufacturer of covered products, we may be required to register as a producer in some European Union countries, and we may incur some financial responsibility for the collection, recycling, treatment and disposal of both new products sold, and products already sold prior to the WEEE Directive’s enforcement date, including the products of other manufacturers where these are replaced by our own products. European Union Directive 2002/95/EC on the Restriction of the Use of Hazardous Substances in electrical and electronic equipment, known as the “RoHS Directive,” restricts the use of certain hazardous substances, including mercury, lead and cadmium in specified covered products; however, the RoHS Directive currently exempts monitoring instruments from its requirements. If the European Commission were to remove this exemption in the future, we would be required to change our manufacturing processes, and redesign products regulated under the RoHS Directive in order to be able to continue to offer them for sale within the European Union. For some products, substituting certain components containing regulated hazardous substances may be difficult or costly, or result in production delays. We will continue to review the applicability and impact of both directives on the sale of our products within the European Union. Although we cannot currently estimate the extent of such impact, they are likely to result in additional costs, and could require us to redesign or change how we manufacture our products, any of which could adversely affect our operating results. Failure to comply with the directives could result in the imposition of fines and penalties, inability to sell covered products in the European Union and loss of revenues.

We have made, and will continue to make, expenditures to comply with current and future environmental laws. We anticipate that we could incur additional capital and operating costs in the future to comply with existing environmental laws and new requirements arising from new or amended statutes and regulations. In addition, because the applicable regulatory agencies have not yet promulgated final standards for some existing environmental programs, we cannot at this time reasonably estimate the cost for compliance with these additional requirements. The amount of any such compliance costs could be material. We cannot predict the impact that future regulations will impose upon our business.

Business

FDA Regulation of Products

Some of the products that we are developing are subject to regulation under the FDC Act. In particular, our Trimetasphere™ nanomaterial-based MRI contrast agent and our ultrasound diagnostic devices for measuring certain medical conditions will be considered a drug and medical devices, respectively, under the FDC Act. Both the statutes and regulations promulgated under the FDA Act govern, among other things, the testing, manufacturing, safety efficacy, labeling, storage, recordkeeping, advertising and other promotional practices involving the regulation of drug and devices.

New Drugs

Obtaining FDA approval for a new drug has historically been a costly and time consuming process. Generally, in order to gain FDA premarket approval, a developer first must conduct preclinical studies in the laboratory and in animal model systems to gain preliminary information on an agent’s efficacy and to identify any safety problems. The results of these studies are submitted as a part of an investigational new drug, or IND, application which the FDA must review before human clinical trials of an investigational drug can start. The IND application includes a detailed description of the clinical investigations to be undertaken. In order to commercialize any drug, we must sponsor and file an IND application and be responsible for initiating and overseeing the clinical studies to demonstrate the safety, efficacy and potency that are necessary to obtain FDA approval of any of the products. We will be required to select qualified investigators to supervise the administration of the products and ensure that the investigations are conducted and monitored in accordance with FDA regulations. Clinical trials are normally done in three phases, although the phases may overlap. Phase I trials are concerned primarily with the safety and preliminary effectiveness of the drug, involve fewer than 100 subjects and may take from six months to over one year. Phase II trials typically involve a few hundred patients and are designed primarily to demonstrate effectiveness in treating or diagnosing the disease or condition for which the drug is intended, although short-term side effects and risks in people whose health is impaired may also be examined. Phase III trials are expanded clinical trials with larger numbers of patients which are intended to evaluate the overall benefit-risk relationship of the drug and to gather additional information for proper dosage and labeling of the drug. The process of clinical trials generally takes two to five years to complete, but may take longer. The FDA receives reports on the progress of each phase of clinical testing, and it may require the modification, suspension or termination of clinical trials if it concludes that an unwarranted risk is presented to patients.

If clinical trials of a new product are completed successfully, the sponsor of the product may seek FDA marketing approval. If the product is regulated as a drug, the FDA will require the submission and approval of a new drug application, or NDA, before commercial marketing of the drug. The NDA must include detailed information about the drug and its manufacture and the results of product development, preclinical studies and clinical trials. The testing and approval processes require substantial time and effort, and we cannot guarantee that any approval will be granted on a timely basis, if at all. If questions arise during the FDA review process, approval can take more than five years. Even with the submissions of relevant data, the FDA may ultimately decide that the NDA does not satisfy its regulatory criteria for approval and deny approval or require additional clinical studies. In addition, the FDA may condition marketing approval on the conduct of specific post-marketing studies to further evaluate safety and effectiveness. Even if FDA regulatory clearances are obtained, a marketed product is subject to continual review. Later discovery of previously unknown problems or failure to comply with the applicable regulatory requirements may result in restrictions on the marketing of a product or withdrawal of the product from the market as well as possible civil or criminal sanctions.

Medical Devices

Any device products that we may develop are likely to be regulated by the FDA as medical devices rather than drugs. The nature of the FDA requirements applicable to devices depends on their classification by the FDA. A device developed by us would be automatically classified as a Class III device, requiring pre-market approval, unless the device was substantially equivalent to an existing device that has been classified in Class I or Class II or to a pre-1976 device that has not yet been classified or we convince the FDA to reclassify the device as Class I or Class II. Class I or Class II devices require registration through the 510(k) exemption. If we were unable to demonstrate such substantial equivalence and unable to obtain

Business

reclassification, we would be required to undertake the costly and time-consuming process, comparable to that for new drugs, of conducting preclinical studies, obtaining an investigational device exemption to conduct clinical tests, filing a pre-market approval application, and obtaining FDA approval.

If the device were a Class I product, the general controls of the Federal Food, Drug, and Cosmetic Act, chiefly adulteration, misbranding and good manufacturing practice requirements, would nevertheless apply. If substantial equivalence to a Class II device could be shown, the general controls plus special controls, such as performance standards, guidelines for safety and effectiveness, and post-market surveillance, would apply. While demonstrating substantial equivalence to a Class I or Class II product is not as costly or time-consuming as the pre-market approval process for Class III devices, it can in some cases also involve conducting clinical tests to demonstrate that any differences between the new device and devices already on the market do no affect safety or effectiveness. If substantial equivalence to a pre-1976 device that has not yet been classified has been shown, it is possible that the FDA would subsequently classify the device as a Class III device and call for the filing of pre-market approval applications at that time. If the FDA took that step, then filing an application acceptable to the FDA would be a prerequisite to remaining on the market.

Employees

As of March 31, 2006, we employed 161 people, including 148 people on a full-time basis, 159 in the United States and two internationally. Of these, 33 employees hold Ph.D.s and 39 hold advanced degrees. We have experienced no work stoppages and believe that our employee relations are good.

Facilities

Our corporate headquarters are located in Roanoke, Virginia, and, in late 2006, we will move into 20,000 square feet of leased office space currently under construction at the Riverside Center in Roanoke, Virginia. Additional administrative functions currently located in 14,700 square feet of space in Blacksburg, Virginia, under a lease expiring June 30, 2006 will be moved to the corporate headquarters when construction is complete.

We lease an additional 15,000 square feet of space in Blacksburg, Virginia for research, development, manufacturing and administrative functions. Our Luna Technologies Division occupies an additional 6,310 square foot facility space in Blacksburg, Virginia, also for research, development, manufacturing and administrative functions. In the third quarter of 2006, all of our Blacksburg, Virginia, research, development and manufacturing functions will be consolidated into 32,000 square feet of newly leased space in Blacksburg.

Our Luna nanoWorks Division occupies a 24,000 square foot facility in Danville, Virginia for nanomaterials manufacturing and research and development.

Our facility in Charlottesville, Virginia currently occupies approximately 8,000 square feet for research and development of molecular technology solutions. Our facility in Hampton, Virginia, which is located near the NASA Langley Research Center, occupies approximately 10,000 square feet for research and development of non-destructive evaluation and certain ultrasonic technologies. We also maintain additional office space in McLean, Virginia.

We believe that our existing facilities are adequate for our current needs and suitable additional or substitute space will be available as needed to accommodate expansion of our operations.

Legal Proceedings

Business

business. While management currently believes the amount of ultimate liability, if any, with respect to these actions will not materially affect our financial position, results of operations, or liquidity, the ultimate outcome of any litigation is uncertain. Were an unfavorable outcome to occur, or if protracted litigation were to ensue, the impact could be material to us.

In March 2003, the Office of Inspector General of the Department of Commerce advised us that the government was investigating anonymous allegations of contract improprieties. We have cooperated fully and extensively with that investigation through interviews and document production. In April 2003, the government advised our regulatory counsel that to date no wrongdoing had been identified, although the government indicated that we may not have fully complied with contractual reporting requirements in one or two instances, which the government did not specify. We believe that the investigation has been resolved favorably, based on statements by the government investigator to company employees in June 2003, and that this matter effectively is at an end absent any advice or communication from the government to the contrary. However, if the government pursues this investigation further, there can be no assurance as to how or whether our relationships, business, financial condition or results of operations will ultimately be affected.

On November 9, 2004, we received a subpoena from the Department of Defense’s Office of the Inspector General covering certain government research contracts awarded to us between January 1, 1998 and November 9, 2004 to determine if we had duplicated work in our submission of project reports to the government. In connection with the investigation, the government alleged that duplication occurred in three research reports that we prepared under the contracts. We submitted a response to the Inspector General in September 2005 challenging the government’s findings. On November 15, 2005, we entered into a settlement agreement with the government and received a general release with respect to the civil and administrative claims in this matter in return for a payment of $165,333.

In July 2005, we received a letter from legal counsel retained by a former employee that such law firm is investigating whether such former employee has any claims against us, including breaches of contract, fiduciary duty, implied covenants of good faith and fair dealing as well as potential violations of minority stockholder rights that such former employee may have as a stockholder in one of our subsidiaries. In 2006, we responded to additional inquiries from counsel for such former employee seeking information about the relationship between us and the subsidiary in which the employee holds stock. Although we believe none of these potential claims has merit, we cannot currently predict whether such former employee will file litigation against us or the ultimate outcome of any such potential litigation.

Advisory Board

We have assembled an eleven member advisory board of leaders with backgrounds in government, academia and industry with which we consult on a formal basis regarding strategic and technical matters. In general, they serve on an exclusive basis within a defined field of collaboration.

Benefit Plans

The following section provides more details concerning our 2003 Stock Plan and 2006 Equity Incentive Plan.

2003 Stock Plan

Our 2003 Stock Plan was adopted by our board of directors and approved by our stockholders, as amended, on March 16, 2004. Our 2003 Stock Plan provides for the grant of incentive stock options, within the meaning of Section 422 of the Internal Revenue Code, to our employees and our parent and subsidiary corporations’ employees, and for the grant of nonstatutory stock options to our employees, directors and consultants and our parent and subsidiary corporations’ employees and consultants. We will not grant any additional options under our 2003 Stock Plan following this offering. Instead, we will grant options and other equity-based awards under our 2006 Equity Incentive Plan.

As of March 31, 2006, we have reserved a total of 9,715,000 shares of our common stock for issuance pursuant to the 2003 Stock Plan, of which 443,253 shares have been issued upon exercise of options granted under the 2003 Stock Plan. Also as of March 31, 2006, options to purchase 4,812,367 shares of common stock were outstanding and 235,777 shares were available for future grant under this plan. The maximum aggregate number of shares that may be subject to option and sold under the 2003 Stock Plan is 9,715,000 shares, unless adjusted by the administrator.

Our compensation committee appointed by our board of directors administers our 2003 Stock Plan. The administrator has the power to determine the terms of the options, including the service providers who will receive awards, the number of shares subject to each such option, the exercisability of options and the form of consideration payable upon exercise.

Management

In addition, the administrator determines the exercise price of options granted under our 2003 Stock Plan. With respect to all incentive stock options, the exercise price may not be less than the fair market value of our common stock on the date of grant. The term of an incentive stock option may not exceed ten years, except that with respect to any participant who owns more than 10% of the voting power of all classes of our outstanding stock, the term must not exceed five years and the exercise price may not be less than 110% of the fair market value on the grant date. The administrator determines the term of all other options.

After termination of an employee, director or consultant, he or she may exercise his or her option for the period of time as the administrator may determine. In the absence of a specified time, the option will remain exercisable for three months following termination other than by reason of death or disability and for twelve months following termination for death or disability. If, on the date of termination, the employee, director or consultant is not vested as to his or her entire option, the shares covered by the unvested portion of the option will revert to the 2003 Stock Plan.

Unless the administrator provides otherwise, our 2003 Stock Plan does not allow for the transfer of options other than by will or the laws of descent and distribution and only the recipient of an option may exercise an option during his or her lifetime.

Our 2003 Stock Plan provides that in the event of our “change in control,” the successor corporation or its parent or subsidiary will assume or substitute an equivalent award for each outstanding option. If there is no assumption or substitution of outstanding options, the administrator will provide notice to the recipient that he or she has the right to exercise the option as to all of the shares subject to the option for a period of 15 days from the date of such notice. The option will terminate upon the expiration of that 15-day period.

Our 2003 Stock Plan will automatically terminate in 2014, unless we terminate it sooner. In addition, our board of directors has the authority to amend, suspend or terminate the 2003 Stock Plan, provided such action does not impair the rights of any participant. Our board of directors has decided to suspend the 2003 Stock Plan as of the completion of this offering.

2006 Equity Incentive Plan

Our board of directors recommended that our stockholders approve our 2006 Equity Incentive Plan on January 19, 2006, and the plan is pending their approval. Our 2006 Equity Incentive Plan provides for the grant of incentive stock options, within the meaning of Section 422 of the Internal Revenue Code, to our employees and our parent and subsidiary corporations’ employees, and for the grant of nonstatutory stock options, restricted stock, stock appreciation rights, performance units and performance shares to our employees, directors and consultants and our parent and subsidiary corporations’ employees and consultants.

We have reserved a total of 3,000,000 shares of our common stock for issuance pursuant to the 2006 Equity Incentive Plan plus (a) any shares remaining available for grant under our 2003 Stock Plan as of the effective date of this offering and (b) any shares that otherwise would have been returned to our 2003 Stock Plan on or after the effective date of this offering as a result of termination of options or the repurchase of shares issued under the 2003 Stock Plan. In addition, our 2006 Equity Incentive Plan provides for annual increases in the number of shares available for issuance thereunder on the first day of each fiscal year, beginning with our fiscal year 2007, equal to the least of:

10% of the outstanding shares of our common stock on the first day of the fiscal year;

3,000,000 shares; and

such other amounts as our board of directors may determine.

Our compensation committee of our board of directors administers our 2006 Equity Incentive Plan. In the case of awards intended to qualify as “performance-based compensation” within the meaning of Section 162(m) of the Internal Revenue Code, the committee or a subcommittee of that committee granting the awards will consist of two or more “outside directors”

Management

within the meaning of Section 162(m) of the Code. The administrator has the power to determine the terms of the awards, including the exercise price, the number of shares subject to each such award, the exercisability of the awards and the form of consideration payable upon exercise. The administrator also has the authority to institute an exchange program whereby the exercise prices of outstanding awards may be reduced or outstanding awards may be surrendered in exchange for awards with a lower exercise price.

The administrator determines the exercise price of options granted under our 2006 Equity Incentive Plan, but with respect to all incentive stock options, the exercise price may not be less than the fair market value of our common stock on the date of grant. The term of an incentive stock option may not exceed ten years, except that with respect to any participant who owns more than 10% of the voting power of all classes of our outstanding stock, the term must not exceed five years and the exercise price may not be less than 110% of the fair market value on the grant date. The administrator determines the term of all other options.

No optionee may be granted in any fiscal year an option to purchase more than 750,000 shares. However, in connection with his or her initial service, an optionee may be granted an option to purchase up to 2,750,000 shares.

After termination of an employee, director or consultant, he or she may exercise his or her option for the period of time stated in the option agreement. Generally, if termination is due to death or disability, the option will remain exercisable for 12 months. In all other cases, the option will generally remain exercisable for three months. However, an option generally may not be exercised later than the expiration of its term.

Stock appreciation rights may be granted under our 2006 Equity Incentive Plan. Stock appreciation rights allow the recipient to receive the appreciation in the fair market value of our common stock between the date of grant and the exercise date. The administrator determines the terms of stock appreciation rights, including when such rights become exercisable and whether to pay the appreciation in cash or with shares of our common stock, or a combination thereof; however, stock appreciation rights expire under the same rules that apply to stock options.

Restricted stock may be granted under our 2006 Equity Incentive Plan. Restricted stock awards are shares of our common stock that vest in accordance with terms and conditions established by the administrator. The administrator will determine the number of shares of restricted stock granted to any participant. The administrator may impose whatever conditions to vesting it determines to be appropriate. For example, the administrator may set restrictions based on the achievement of specific performance goals. Shares of restricted stock that do not vest are subject to our right of repurchase or forfeiture.

Performance units and performance shares may be granted under our 2006 Equity Incentive Plan. Performance units and performance shares are awards that will result in a payment to a participant only if performance goals established by the administrator are achieved or the awards otherwise vest. The administrator will establish organizational or individual performance goals in its discretion, which, depending on the extent to which they are met, will determine the number and/or the value of performance units and performance shares to be paid out to participants. Performance units will have an initial dollar value established by the administrator prior to the grant date. Performance shares will have an initial value equal to the fair market value of our common stock on the grant date. Payment for performance units and performance shares may be made in cash or in shares of our common stock with equivalent value, or in some combination, as determined by the administrator.

Unless the administrator provides otherwise, our 2006 Equity Incentive Plan does not allow for the transfer of awards and only the recipient of an award may exercise an award during his or her lifetime.

Our 2006 Equity Incentive Plan provides that in the event of our “change in control,” the successor corporation or its parent or subsidiary will assume or substitute an equivalent award for each outstanding award. If there is no assumption or substitution of outstanding awards, the administrator will provide notice to the recipient that he or she has the right to exercise the option and stock appreciation right as to all of the shares subject to the award, all restrictions on restricted stock will lapse, and all

Management

performance goals or other vesting requirements for performance shares and units will be deemed achieved, and all other terms and conditions met. The option or stock appreciation right will terminate upon the expiration of the period of time the administrator provides in the notice. In the event the service of an outside director is terminated on or following a change in control, other than pursuant to a voluntary resignation, his or her options and stock appreciation rights will fully vest and become immediately exercisable, all restrictions on restricted stock will lapse, and all performance goals or other vesting requirements for performance shares and units will be deemed achieved, and all other terms and conditions met.

Our 2006 Equity Incentive Plan will automatically terminate in 2016, unless we terminate it sooner. In addition, our board of directors has the authority to amend, suspend or terminate the 2006 Equity Incentive Plan provided such action does not impair the rights of any participant.

Employment Agreements and Change in Control Arrangements

Employment at our company is at will. As discussed in note 14 of the Luna Technologies, Inc. 2004 financial statements included elsewhere in this prospectus, the president of that company previously had an employment agreement with Luna Technologies. In connection with our repurchase and consolidation of Luna Technologies, all employment agreements with employees in that subsidiary have been terminated. In the period from April 2005 through October 2005, we entered into officer employment letters with Scott A.

Goehrke, our Chief Operating Officer, Aaron S. Hullman, our Vice President and General Counsel, and Kenneth D. Ferris, President of our Luna Advanced Systems Division.

Certain relationships and related party transactions

We describe below the transactions and series of similar transactions that have occurred this year or during the last three fiscal years to which we or our subsidiaries were a party or will be a party, in which:

the amounts involved exceeded or will exceed $60,000; and

a director, executive officer, holder of more than 5% of our common stock or any member of their immediate family had or will have a direct or indirect material interest.

Luna Technologies Acquisition

In September 2005, we acquired all of the outstanding shares of common stock and preferred stock of Luna Technologies that we did not already own in exchange for 582,884 shares of our Class B Common Stock, excluding 2,035 shares of our Class B Common Stock reserved for issuance upon the exercise of warrants that were exchanged for warrants formerly issued by Luna Technologies. An additional 111,013 shares of our Class B Common Stock and warrants exercisable for 388 shares of our Class B Common Stock were held in escrow at closing pending completion of certain additional equity investments by Carilion Health System, of which 41,634 shares and warrants exercisable for 145 shares were released from escrow on December 30, 2005 upon closing of an additional $3.0 million equity investment by Carilion Health System. The remaining 69,390 escrow shares and warrants exercisable for 146 shares are expected to be cancelled upon the closing of this offering. In addition, the stockholders receiving shares of our common stock in connection with our acquisition of Luna Technologies have a redemption right for a certain percentage of the outstanding shares issued pursuant to that transaction. That redemption right will be cancelled upon the effectiveness of our offering.

Dr. Kent Murphy, our President, Chief Executive Officer, Secretary and Treasurer, was also Chairman of the Board of Directors of Luna Technologies immediately prior to the acquisition and a former stockholder of Luna Technologies. Shortly prior to this transaction, Dr. Murphy sold all of his shares of Luna Technologies stock to two other Luna Technologies stockholders for an aggregate purchase price of approximately $10,600; as a result, Dr. Murphy did not receive any additional shares of our common stock in connection with the transaction. Also, in connection with this transaction, John Goehrke, the Chief Executive Officer of Luna Technologies, became our Chief Operating Officer and Mark Froggatt, a founder and employee of Luna Technologies, became our Chief Technology Officer. All former employees of Luna Technologies as of September 30, 2005 who became employees of Luna Innovations after the transaction received options to purchase shares of our common stock, subject to a three year vesting schedule. An aggregate of 404,139 options were issued to former Luna Technologies employees in connection with this transaction. In addition, Mr. Goehrke received $75,000 from Luna Technologies as a bonus paid prior to close of that transaction, $150,000 from two other Luna Technologies stockholders and $25,000 from us as a signing bonus in connection with the transaction. Dr. Paul Torgersen, a member of our board of directors, was also a former stockholder in Luna Technologies and received common stock of Luna Innovations upon the same terms and conditions as other stockholders of Luna Technologies. Scott Graeff, a former member of our board of directors and our Chief Financial Officer and Executive Vice President, Corporate Development, was formerly acting Chief Financial Officer of Luna Technologies from August 2003 until July 2005.

Because there was no public market for our shares at the time of the transaction, the number of shares of our nonvoting Class B Common Stock paid as consideration in the transaction was arrived at by negotiating a percentage of the financial ownership of our company that the Luna Technologies stockholders would receive. As a result, the parties to the transaction did not assign a specific value to the shares issued in the transaction. The number of shares and percentage were determined by arms-length negotiations with the three largest stockholders of Luna Technologies prior to the acquisition. Subsequent to this transaction, we engaged an independent third-party appraiser, who estimated the value of Luna Technologies to be approximately $2.0 million as of September 30, 2005 and also estimated that our nonvoting Class B Common Stock was valued at $1.63 per share on that date, or $948,735 for the 582,884 shares that were issued at closing. The independent third-party appraiser also estimated that our nonvoting Class B Common Stock was valued at $1.65 per share on December 30, 2005, or $68,502 for the 41,634 shares that were released from escrow on that date.

Certain relationships and related party transactions

Financing Transactions

In August 2005, Carilion Health System purchased 1,492,032 shares of our Class C Common Stock for an aggregate purchase price of $7.0 million. Dr. Edward Murphy, Chairman and Chief Executive Officer of Carilion Health System, became a member of our board of directors in connection with this transaction and was appointed chair of the Compensation Committee of our board of directors in October 2005. The purchase price for the securities was negotiated at arms length by the parties. In connection with this transaction, Scott Graeff, a former member of our board of directors and our Chief Financial Officer and Executive Vice President, Corporate Development, received fully vested stock options to purchase 169,570 shares of our common stock.

In the definitive transaction documents relating to the August 2005 financing transaction, Carilion Health System agreed to purchase additional shares of our Class C Common Stock in two tranches for aggregate additional consideration of $8.0 million upon the achievement of certain milestones relating to, among other things, our filing of Investigational New Drug applications with the FDA. However, in December 2005, we agreed with Carilion Health System to terminate these milestone requirements in connection with Carilion Health System’s purchase of an additional 639,442 shares of our Class C Common Stock for an aggregate purchase price of $3.0 million. Concurrent with the December 2005 equity investment, Carilion Health System invested $5.0 million aggregate principal amount in a series of senior convertible promissory notes. These notes accrue simple interest at a rate of 6.0% per year and are due and payable on December 30, 2009 or a later date if extended by the holders of a majority of the aggregate principal amount of the notes, absent acceleration due to an event of default. The holders of a majority of the aggregate principal amount of the notes may also extend the maturity date of these notes for one additional year by providing notice to us and may further extend the maturity date for up to an additional three consecutive one year periods if we are not eligible for or have elected not to pursue SBIR funding. After the first extension, if any, we will have the right to repay any accrued interest in cash rather than common stock. The holders of these notes have the option to convert their notes (subject to certain limitations) into shares of our common stock at maturity or upon the occurrence of certain events prior to this offering. In addition, the holders may convert their notes (subject to certain limitations) into shares of common stock if we are no longer eligible for SBIR grants or have not applied for an SBIR grant within the preceding 12 months. These notes entitle the holders to convert the principal amount of the notes into an aggregate of 1,065,740 shares of common stock and to convert accrued interest on the notes into up to an aggregate of 511,553 shares of our common stock. Under the terms of these notes, we agreed that we will not, without the prior written consent of the holders of a majority of the aggregate principal amount of the notes, draw down any amount under our existing senior secured revolving credit facility with First National Bank or incur additional indebtedness other than under certain limited conditions.

In addition, so long as Carilion Health System continues to hold any of the senior convertible promissory notes or 423,923 shares of voting common stock, and to the extent such technology is not restricted by other contractual arrangements in effect as of August 2, 2005, we have an obligation to disclose to Carilion Consolidated Laboratory for review on a confidential basis, that technology developed now or in the future by our employees or the employees of our affiliates which impacts, or has an application to, the clinical laboratory industry, at least sixty days prior to disclosing such technology to any third-party for purpose of commercialization. Carilion Consolidated Laboratory is an affiliate of Carilion Health System, and Dr. Edward Murphy, Chairman and Chief Executive Officer of Carilion Health System, is a member of our board of directors. We do not have an obligation to offer either Carilion Health System or Carilion Consolidated Laboratory the opportunity to participate in any of our commercialization efforts. The purpose of providing Carilion Consolidated Laboratory with a limited right to review this technology is to allow Carilion Consolidated Laboratory the opportunity to make a first offer to license or acquire this technology, but we will not be obligated to accept such offers, if any, from Carilion Consolidated Laboratory.

Finally, in connection with these transactions, we granted certain anti-dilution protections to Carilion Health System as holders of our Class C Common Stock. These protections provide that upon an initial public offering, all outstanding shares of Class C Common Stock shall convert at a rate resulting in conversion to 22.2% of the aggregate voting rights of Class A Common Stock and 20.06% of the outstanding shares of Class B Common Stock on a fully-diluted basis, both of which classes would automatically convert to shares of our common stock. Based on our capitalization at March 31, 2006 and our expected

Certain relationships and related party transactions

capitalization upon this offering, Carilion Health System would receive up to an additional 96,724 shares of our common stock upon effectiveness of this offering.

Other Agreements with Executive Officers

Pursuant to that certain Cash Bonus Agreement dated March 21, 2003, by and between us and Michael Gunther, we were obligated to pay Mr. Gunther a fixed cash bonus over a period of three years, of which the last $180 thousand payment was made in January 2006. Mr. Gunther was formerly an executive officer, our Vice President of Operations, and he is currently our Vice President, Intellectual Property.

Lease

We have entered into an agreement with Carilion Medical Center to lease 20,000 square feet of office space currently being built at the Riverside Center in Roanoke, Virginia. The landlord of this property, Carilion Medical Center, is an affiliate of Carilion Health System, currently our second largest stockholder. Dr. Edward Murphy, Chairman and Chief Executive Officer of Carilion Health System became a member of our board of directors in connection with an investment by Carilion Health System in August 2005. Dr. Murphy was appointed chairman of the Compensation Committee of our board of directors in October 2005.

Registration Rights Agreements

In connection with the investment by Carilion Health System in August 2005 and its subsequent investment in December 2005, we entered into an amended and restated investor rights agreement dated as of December 30, 2005, with Carilion Health System and Dr. Kent Murphy. Dr. Murphy is our President, Chief Executive Officer, Secretary, Treasurer and Chairman and is also our largest individual stockholder. Pursuant to this agreement, under certain circumstances Carilion Health System and Dr. Kent Murphy are entitled to require us to register their shares of common stock under the securities laws for resale.

In connection with the acquisition of Luna Technologies in September 2005, we granted the former stockholders of Luna Technologies certain registration rights in the event we elect to file a registration statement for our common stock. Such rights are set forth in that certain Stock Purchase Agreement dated as of September 30, 2005 with the former stockholders of Luna Technologies. Unlike Carilion Health System, the former Luna Technologies stockholders do not have the right to require us to register their shares of common stock for resale if we are not otherwise filing a registration statement to sell securities. For additional information, see “Description of capital stock—Registration Rights.”

Indemnification Agreements

We have entered into an indemnification agreement with each of our directors and officers. The indemnification agreements and our amended and restated certificate of incorporation and bylaws require us to indemnify our directors and officers to the fullest extent permitted by Delaware law.

Principal stockholders

The following table sets forth certain information with respect to beneficial ownership of our common stock, as of March 31, 2006, after giving effect to the conversion of our Class A Common Stock, Class B Common Stock and Class C Common Stock into shares of our common stock, by:

each beneficial owner of 5% or more of the outstanding shares of our common stock;

each of our directors;

each of our named executive officers; and

all of our executive officers and directors as a group.

Beneficial ownership is determined in accordance with the rules of the SEC. In computing the number of shares beneficially owned by a person and the percentage ownership of that person, shares of common stock subject to options or warrants held by that person that are currently exercisable or exercisable within 60 days of March 31, 2006 are deemed outstanding, but are not deemed outstanding for computing the percentage ownership of any other person. Percentage of beneficial ownership is based upon 6,234,325 shares of common stock outstanding as of March 31, 2006 after giving effect to the conversion of our Class A Common Stock, Class B Common Stock and Class C Common Stock into shares of our common stock which includes the conversion of Class C common stock such that an additional 96,724 is issued to Carilion Health Systems. To our knowledge, except as set forth in the footnotes to this table and subject to applicable community property laws, each person named in the table has sole voting and investment power with respect to the shares set forth opposite such person’s name.

Description of capital stock

The following information describes our common stock and preferred stock, as well as our convertible securities and options and warrants to purchase our common stock and provisions of our amended and restated certificate of incorporation and bylaws. This description is only a summary. You should also refer to our amended and restated certificate of incorporation and bylaws, which have been filed with the Securities and Exchange Commission as exhibits to our registration statement, of which this prospectus forms a part.

Upon the completion of this offering our authorized capital stock will consist of 100,000,000 shares of common stock with a $0.001 par value per share, and 5,000,000 shares of preferred stock with a $0.001 par value per share.

Common Stock

As of March 31, 2006, after giving effect to the conversion of all outstanding Class A Common Stock, Class B Common Stock and Class C Common Stock into shares of common stock, there were an aggregate of 6,137,601 shares of common stock outstanding that were held of record by 44 stockholders. Based on our capitalization at March 31, 2006 and our expected capitalization upon this offering, an additional 96,724 shares of our common stock would be issued to Carilion Health System upon effectiveness of this offering in connection with certain anti-dilution provisions afforded to that stockholder. An additional 69,390 shares of Class B Common Stock issued or reserved for issuance in connection with the acquisition of Luna Technologies, Inc. were held in escrow on that date and are expected to be cancelled prior to the completion of this offering. After giving effect to the sale of common stock offered in this offering, including the issuing of 96,724 to Carilion Health System pursuant to its anti-dilution rights available upon this offering, there will be 9,734,325 shares of common stock outstanding. As of March 31, 2006, there were outstanding options to purchase a total of 4,812,367 shares of our Class B Common Stock under our 2003 Stock Plan, which options will be automatically converted into options to purchase shares of our common stock upon completion of this offering. We recently adopted our 2006 Equity Incentive Plan, under which no options have been issued as of yet.

Holders of common stock are entitled to one vote for each share held of record on all matters submitted to a vote of the stockholders. Our stockholders do not have cumulative voting rights in the election of directors. Accordingly, holders of a majority of the shares voting are able to elect all directors being elected at such time. Subject to preferences that may be granted to any then outstanding preferred stock, holders of common stock are entitled to receive ratably only those dividends as may be declared by the board of directors out of funds legally available therefor. See “Dividend policy.” In the event of our liquidation, dissolution or winding up, holders of common stock are entitled to share ratably in all of our assets remaining after we pay our liabilities and distribute the liquidation preference of any then outstanding preferred stock. Holders of common stock have no preemptive or other subscription or conversion rights. Upon the completion of this offering, there will be no redemption or sinking fund provisions applicable to the common stock.

Preferred Stock

Upon the completion of this offering, our board of directors will have the authority, without further action by the stockholders, to issue up to 5,000,000 shares of preferred stock in one or more series and to fix the rights, preferences, privileges and restrictions thereof. These rights, preferences and privileges could include dividend rights, conversion rights, voting rights, terms of redemption, liquidation preferences, sinking fund terms and the number of shares constituting any series or the designation of such series, any or all of which may be greater than the rights of common stock. The issuance of preferred stock could adversely affect the voting power of holders of common stock and the likelihood that such holders will receive dividend payments and payments upon liquidation. In addition, the issuance of preferred stock could have the effect of delaying, deferring or preventing a change in our control or other corporate action. Upon completion of this offering, no shares of preferred stock will be outstanding, and we have no present plan to issue any shares of preferred stock.

Warrants

As of March 31, 2006, there were outstanding warrants (not subject to escrow) to purchase 61,214 shares of our common stock at a weighted-average exercise price of $3.04 per share held by 30 warrantholders of record. In addition, there were

Description of capital stock

outstanding warrants to purchase 146 shares of common stock at an exercise price of $37.26 held in escrow as of March 31, 2006, which are expected to be cancelled upon the closing of this offering. No other warrants remain outstanding or will be exercisable following the completion of this offering.

Senior Convertible Promissory Notes

As of March 31, 2006, we had $5.0 million aggregate principal amount of a series of senior convertible promissory notes outstanding. The holders of these notes have the option to convert their notes (subject to certain limitations) into shares of common stock at maturity or upon the occurrence of certain events prior to this offering. In addition, the holders may convert their notes (subject to certain limitations) into shares of common stock if we are no longer eligible for SBIR grants or have not applied for an SBIR grant within the preceding 12 months. These notes entitle the holders to convert the principal amount of the notes into an aggregate of 1,065,740 shares of common stock and to convert accrued interest on the notes into up to an aggregate of 511,553 shares of our common stock.

Registration Rights

After the closing of this offering, the holders of approximately 5,489,872 shares of our common stock will be entitled to certain rights with respect to the registration of such shares under the Securities Act. All of these holders may require us to register the resale of all or a portion of their shares on Form S-3, subject to certain conditions and limitations. Of these holders, the holders of approximately 4,865,359 shares of our common stock have additional registration rights. For example, in the event that we propose to register any of our securities under the Securities Act, either for our own account or for the account of other security holders, the holders of these approximately 4,865,359 shares are entitled to notice of such registration and are entitled to include their common stock in such registration, subject to certain marketing and other limitations. Beginning 180 days after the closing of this offering, the holders of at least 50% of such 4,865,359 shares of our common stock have the right to require us, on not more than two occasions, to file a registration statement on Form S-1 under the Securities Act in order to register the resale of their shares of common stock. We may, in certain circumstances, defer such registrations and the underwriters have the right, subject to certain limitations, to limit the number of shares included in such registrations. In addition, these holders have certain “piggyback” registration rights. If we propose to register any of our equity securities under the Securities Act other than pursuant to the registration rights noted above or specified excluded registrations, these holders may require us to include all or a portion of their registrable securities in the registration and in any related underwriting. In an underwritten offering, the managing underwriter, if any, has the right, subject to specified conditions, to limit the number of registrable securities such holders may include. Additionally, such piggyback registrations are subject to delay or termination of the registration under certain circumstances. The underwriters named in this prospectus have notified us that no holders of registration rights will be permitted to include any of their shares in this offering.

Anti-Takeover Effects of Provisions of the Amended and Restated Certificate of Incorporation and Bylaws

Our amended and restated certificate of incorporation, to be effective upon completion of this offering, will provide for our board of directors to be divided into three classes, with staggered three-year terms. Only one class of directors will be elected at each annual meeting of our stockholders, with the other classes continuing for the remainder of their respective three-year terms. Because our stockholders do not have cumulative voting rights, our stockholders representing a majority of the shares of common stock outstanding will be able to elect all of our directors. Our amended and restated certificate of incorporation and bylaws, to be effective upon completion of this offering, will provide that only our board of directors, chairman of the board, chief executive officer or president (in the absence of a chief executive officer) may call a special meeting of stockholders. Our amended and restated certificate of incorporation, to be effective upon completion of this offering, will require a 66 2/3% stockholder vote for the amendment, repeal or modification of certain provisions of our amended and

Description of capital stock

restated certificate of incorporation and bylaws relating to the absence of cumulative voting, the classification of our board of directors, and the designated parties entitled to call a special meeting of the stockholders.

The combination of a classified board, the lack of cumulative voting and the 66 2/3% stockholder voting requirements will make it more difficult for our existing stockholders to replace our board of directors as well as for another party to obtain control of us by replacing our board of directors. Since our board of directors has the power to retain and discharge our officers, these provisions could also make it more difficult for existing stockholders or another party to effect a change in management. In addition, the authorization of undesignated preferred stock makes it possible for our board of directors to issue preferred stock with voting or other rights or preferences that could impede the success of any attempt to change our control.

These provisions may have the effect of deterring hostile takeovers or delaying changes in our control or management. These provisions are intended to enhance the likelihood of continued stability in the composition of our board of directors and in the policies they implement, and to discourage certain types of transactions that may involve an actual or threatened change of our control. These provisions are designed to reduce our vulnerability to an unsolicited acquisition proposal. The provisions also are intended to discourage certain tactics that may be used in proxy fights. However, such provisions could have the effect of discouraging others from making tender offers for our shares and, as a consequence, they also may inhibit fluctuations in the market price of our shares that could result from actual or rumored takeover attempts. Such provisions may also have the effect of preventing changes in our management.

Section 203 of the General Corporation Law of the State of Delaware

We are subject to Section 203 of the General Corporation Law of the State of Delaware, which prohibits a Delaware corporation from engaging in any business combination with any interested stockholder for a period of three years after the date that such stockholder became an interested stockholder, with the following exceptions:

before such date, the board of directors of the corporation approved either the business combination or the transaction that resulted in the stockholder becoming an interested stockholder;

upon completion of the transaction that resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the transaction began, excluding for purposes of determining the voting stock outstanding (but not the outstanding voting stock owned by the interested stockholder) those shares owned (i) by persons who are directors and also officers and (ii) employee stock plans in which employee participants do not have the right to determine confidentially whether shares held subject to the plan will be tendered in a tender or exchange offer; or

on or after such date, the business combination is approved by the board of directors and authorized at an annual or special meeting of the stockholders, and not by written consent, by the affirmative vote of at least 66²/3% of the outstanding voting stock that is not owned by the interested stockholder.

In general, Section 203 defines business combination to include the following:

any merger or consolidation involving the corporation and the interested stockholder;

any sale, lease, exchange, mortgage, transfer, pledge or other disposition of 10% or more of either the assets or outstanding stock of the corporation involving the interested stockholder;

subject to certain exceptions, any transaction that results in the issuance or transfer by the corporation of any stock of the corporation to the interested stockholder;

any transaction involving the corporation that has the effect of increasing the proportionate share of the stock of any class or series of the corporation beneficially owned by the interested stockholder; or

Description of capital stock

the receipt by the interested stockholder of the benefit of any loans, advances, guarantees, pledges or other financial benefits by or through the corporation.

In general, Section 203 defines interested stockholder as an entity or person who, together with affiliates and associates, beneficially owns, or within three years prior to the determination of interested stockholder status did own, 15% or more of the outstanding voting stock of the corporation.

Shares eligible for future sale

We will have 9,734,325 shares of common stock outstanding after the completion of this offering (10,334,325 shares if the underwriters’ over-allotment is exercised in full). Of those shares, the 3,500,000 shares of common stock sold in the offering (4,100,000 shares if the underwriters’ over-allotment option is exercised in full) will be freely transferable without restriction, unless purchased by persons deemed to be our “affiliates” as that term is defined in Rule 144 under the Securities Act. Any shares purchased by an affiliate may not be resold except pursuant to an effective registration statement or an applicable exemption from registration, including an exemption under Rule 144 promulgated under the Securities Act. The remaining 6,234,325 shares of common stock to be outstanding immediately following the completion of this offering are “restricted,” which means they were originally sold in offerings that were not registered under the Securities Act. Restricted shares may be sold through registration under the Securities Act or under an available exemption from registration, such as provided through Rule 144, which rules are summarized below. Taking into account the 180-day lock up agreements described below, and assuming the underwriters do not release any stockholders from these agreements, shares of our common stock will be available for sale in the public market as follows:

566 shares will be immediately eligible for sale in the public market without restriction pursuant to Rule 144(k);

one percent of the then outstanding shares of our common stock (approximately 102,343 shares immediately after the offering); or

the average weekly trading volume in the common stock on The Nasdaq National Market during the four calendar weeks preceding the sale.

the shares in the public market without regard to the volume limitations, manner of sale provisions, notice requirements or the availability of current public information we refer to above.

Rule 701

Any of our employees, officers, directors or consultants who purchased his or her shares before the completion of this offering or who holds options as of that date pursuant to a written compensatory plan or contract is entitled to rely on the resale provisions of Rule 701, which permits non-affiliates to sell their Rule 701 shares without having to comply with the public information, holding period, volume limitation or notice provisions of Rule 144 and permits affiliates to sell their Rule 701 shares without having to comply with Rule 144’s holding-period restrictions, in each case commencing 90 days after completion of this offering. Neither Rule 144, Rule 144(k) nor Rule 701 supersedes the contractual obligations of our security holders set forth in the lock-up agreements described below.

Stock Options

Within three months following the completion of this offering, we intend to file a registration statement on Form S-8 under the Securities Act to register 12,715,000 shares of common stock reserved for issuance under our 2003 Stock Plan and 2006 Equity Incentive Plan, thus permitting the resale of such shares.

Prior to the completion of this offering, there has been no public market for our common stock, and any sale of substantial amounts in the open market may adversely affect the market price of our common stock offered hereby.

Warrants

In addition, holders of warrants exerciseable for up to 61,214 shares of common stock may exercise their rights and subsequently sell the underlying shares in the public market.

Lock-Up Agreements

Subject to certain exceptions, each of our officers, directors and security holders have agreed not to offer to sell, sell, pledge, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right, or warrant to purchase, lend, or otherwise transfer or dispose of, directly or indirectly, any shares of our common stock or any securities convertible into or exercisable or exchangeable for our common stock, or enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of our common stock, whether any transaction is to be settled by delivery of our common stock or other securities, in cash or otherwise, without the prior written consent of ThinkEquity Partners LLC for a period of 180 days after the date of this prospectus. Notwithstanding the foregoing, for the purpose of allowing the underwriters to comply with NASD Rule 2711(f)(4), if (1) during the last 17 days of the initial 180-day lock-up period, we release earnings results or material news or a material event relating to us occurs or (2) prior to the expiration of the initial 180-day lock-up period, we announce that we will release earnings results during the 16-day period beginning on the last day of the initial 180-day lock-up period, then in each case the initial 180-day lock-up period will be extended until the expiration of the 18-day period beginning on the date of release of the earnings results or the occurrence of the material news or material event, as applicable.

Stock Sale Restriction Agreements

We have the right to waive any of these resale restrictions for employees and management at our discretion, and in such instance, the shares would become freely tradable.

U.S. federal income and estate tax consequences to non-U.S. holders

This section summarizes certain material U.S. federal income and estate tax considerations relating to the ownership and disposition of common stock by non-U.S. holders. This summary does not provide a complete analysis of all potential tax considerations. The information provided below is based on existing authorities. These authorities may change, or the IRS might interpret the existing authorities differently. In either case, the tax considerations of owning or disposing of common stock could differ from those described below. For purposes of this summary, a “non-U.S. holder” is any holder other than a citizen or resident of the United States, a corporation organized under the laws of the United States or any state, a trust that is (i) subject to the primary supervision of a U.S. court and the control of one of more U.S. persons or (ii) has a valid election in effect under applicable U.S. Treasury regulations to be treated as a U.S. person or an estate whose income is subject to U.S. income tax regardless of source. If a partnership or other flow-through entity is a beneficial owner of common stock, the tax treatment of a partner in the partnership or an owner of the entity will depend upon the status of the partner or other owner and the activities of the partnership or other entity. The summary generally does not address tax considerations that may be relevant to particular investors because of their specific circumstances, or because they are subject to special rules. Finally, the summary does not describe the effects of any applicable foreign, state or local laws.

INVESTORS CONSIDERING THE PURCHASE OF COMMON STOCK SHOULD CONSULT THEIR OWN TAX ADVISORS REGARDING THE APPLICATION OF THE U.S. FEDERAL INCOME AND ESTATE TAX LAWS TO THEIR PARTICULAR SITUATIONS AND THE CONSEQUENCES OF FOREIGN, STATE, OR LOCAL LAWS AND TAX TREATIES.

Dividends

Any dividend paid to a non-U.S. holder on our common stock will generally be subject to U.S. withholding tax at a 30% rate. The withholding tax might not apply, however, or might apply at a reduced rate, if the non-U.S. holder satisfies the applicable conditions under the terms of an applicable income tax treaty between the United States and the non-U.S. holder’s country of residence. A non-U.S. holder must demonstrate its entitlement to treaty benefits by providing a properly completed Form W-8BEN or appropriate substitute form to us or our paying agent. If the holder holds the stock through a financial institution or other agent acting on the holder’s behalf, the holder will be required to provide appropriate documentation to the agent. The holder’s agent will then be required to provide certification to us or our paying agent, either directly or through other intermediaries. For payments made to a foreign partnership or other flowthrough entity, the certification requirements generally apply to the partners or other owners rather than to the partnership or other entity, and the partnership or other entity must provide the partners’ or other owners’ documentation to us or our paying agent. Special rules, described below, apply if a dividend is effectively connected with a U.S. trade or business conducted by the non-U.S. holder.

Sale of Common Stock

Non-U.S. holders will generally not be subject to U.S. federal income tax on any gains realized on the sale, exchange, or other disposition of common stock. This general rule, however, is subject to several exceptions. For example, the gain would be subject to U.S. federal income tax if:

the gain is effectively connected with the conduct by the non-U.S. holder of a U.S. trade or business (in which case the special rules described below under the caption “Dividends or Gain Effectively Connected with a U.S. Trade or Business” apply);

the non-U.S. holder was a citizen or resident of the United States and thus is subject to special rules that apply to expatriates;

U.S. federal income and estate tax consequences to non-U.S. holders

subject to certain exceptions, the non-U.S. holder is an individual who is present in the United States for 183 days or more in the year of disposition, in which case the gain would be subject to a flat 30% tax, which may be offset by U.S. source capital losses, even though the individual is not considered a resident of the U.S.; or

the rules of the Foreign Investment in Real Property Tax Act, or FIRPTA, described below, treat the gain as effectively connected with a U.S. trade or business.

The FIRPTA rules may apply to a sale, exchange or other disposition of common stock if we are, or were within five years before the transaction, a “U.S. real property holding corporation,” or USRPHC. In general, we would be a USRPHC if interests in U.S. real estate comprised most of our assets. We do not believe that we are a USRPHC or that we will become one in the future.

Dividends or Gain Effectively Connected With a U.S. Trade or Business

If any dividend on common stock, or gain from the sale, exchange or other disposition of common stock, is effectively connected with a U.S. trade or business conducted by the non-U.S. holder, then the dividend or gain will be subject to U.S. federal income tax at the regular graduated rates. If the non-U.S. holder is eligible for the benefits of an income tax treaty between the United States and the holder’s country of residence, any “effectively connected” dividend or gain would generally be subject to U.S. federal income tax only if it is also attributable to a permanent establishment or fixed base maintained by the holder in the United States. Payments of dividends that are effectively connected with a U.S. trade or business, and therefore included in the gross income of a non-U.S. holder, will not be subject to the 30 percent withholding tax. To claim exemption from withholding, the holder must certify its qualification, which can be done by filing a Form W-8ECI. If the non-U.S. holder is a corporation, that portion of its earnings and profits that is effectively connected with its U.S. trade or business would generally be subject to a “branch profits tax” in addition to any regular U.S. federal income tax on the dividend or gain. The branch profits tax rate is generally 30 percent, although an applicable income tax treaty might provide for a lower rate.

U.S. Federal Estate Tax

The estates of nonresident alien individuals are generally subject to U.S. federal estate tax on property with a U.S. situs. Because we are a U.S. corporation, our common stock will be U.S. situs property and therefore will be included in the taxable estate of a nonresident alien decedent. The U.S. federal estate tax liability of the estate of a nonresident alien may be affected by a tax treaty between the United States and the decedent’s country of residence.

Backup Withholding and Information Reporting

The Code and the Treasury regulations require those who make specified payments to report the payments to the IRS. Among the specified payments are dividends and proceeds paid by brokers to their customers. The required information returns enable the IRS to determine whether the recipient properly included the payments in income. This reporting regime is reinforced by “backup withholding” rules. These rules require the payors to withhold tax from payments subject to information reporting if the recipient fails to cooperate with the reporting regime by failing to provide his taxpayer identification number to the payor, furnishing an incorrect identification number, or repeatedly failing to report interest or dividends on his returns. The withholding tax rate is currently 28 percent. The backup withholding rules do not apply to payments to corporations, whether domestic or foreign.

Payments to non-U.S. holders of dividends on common stock will generally not be subject to backup withholding, and payments of proceeds made to non-U.S. holders by a broker upon a sale of common stock will not be subject to information reporting or backup withholding, in each case so long as the non-U.S. holder certifies its nonresident status. Some of the common means of certifying nonresident status are described under “—Dividends.” We must report annually to the IRS any

U.S. federal income and estate tax consequences to non-U.S. holders

dividends paid to each non-U.S. holder and the tax withheld, if any, with respect to such dividends. Copies of these reports may be made available to tax authorities in the country where the non-U.S. holder resides.

Any amounts withheld from a payment to a holder of common stock under the backup withholding rules can be credited against any U.S. federal income tax liability of the holder.

THE PRECEDING DISCUSSION OF U.S. FEDERAL INCOME TAX CONSIDERATIONS IS FOR GENERAL INFORMATION ONLY IT IS NOT TAX ADVICE. EACH PROSPECTIVE INVESTOR SHOULD CONSULT ITS OWN TAX ADVISOR REGARDING THE PARTICULAR U.S. FEDERAL, STATE, LOCAL, AND FOREIGN TAX CONSEQUENCES OF PURCHASING, HOLDING, AND DISPOSING OF OUR COMMON STOCK, INCLUDING THE CONSEQUENCES OF ANY PROPOSED CHANGE IN APPLICABLE LAWS.

Underwriting

ThinkEquity Partners LLC is acting as sole book-runner of this offering, and, together with WR Hambrecht + Co, LLC and Merriman Curhan Ford & Co., are acting as representatives of the underwriters named below. Subject to the terms and conditions stated in the underwriting agreement, each underwriter named below has agreed to purchase, and we have agreed to sell to that underwriter, the number of shares of common stock set forth opposite that underwriter’s name.


Underwriters		Number of Shares
ThinkEquity Partners LLC
WR Hambrecht + Co, LLC
Merriman Curhan Ford & Co.

Total		3,500,000

The underwriting agreement provides that the obligations of the underwriters to purchase the shares included in this offering are subject to approval of legal matters by counsel and to other conditions. The underwriters are obligated to purchase all the shares, other than those covered by the over-allotment option described below, if they purchase any of the shares.

The underwriters have advised us that they propose to offer the shares initially to the public at $ per share. The underwriters propose to offer the shares to certain dealers at the same price less a concession of not more than $ per share. The underwriters may allow and the dealers may reallow a concession of not more than $ per share on sales to certain other brokers and dealers. If all the shares are not sold at the initial public offering price, the representatives may change the offering price and other selling terms.

We have granted to the underwriters an over-allotment option to purchase up to an additional 600,000 shares of our common stock from us at the same price as to the public, and with the same underwriting discount, as set forth on the front cover of this prospectus. The underwriters may exercise this option any time during the 30-day period after the date of this prospectus, but only to cover over-allotments, if any. To the extent the underwriters exercise the option, each underwriter will become obligated, subject to certain conditions, to purchase approximately the same percentage of the additional shares as it was obligated to purchase under the underwriting agreement.

Each underwriter has represented, warranted and agreed that:

it has not offered or sold and, prior to the expiry of a period of 12 months from the closing date, will not offer or sell any shares included in this offering to any persons in the United Kingdom other than to qualified investors (within the meaning of 586(7) of the Financial Services and Markets Act 2000, or FSMA, or otherwise in circumstances which do not comprise an offer of transferable securities to the public for the purposes of 585(1) FSMA;

it has only communicated and caused to be communicated and will only communicate or cause to be communicated any invitation or inducement to engage in investment activity (within the meaning of section 21 of the Financial Services and Markets Act 2000 (“FSMA”)) received by it in connection with the issue or sale of any shares included in this offering in circumstances in which section 21(1) of the FSMA does not apply to us; and

it has complied and will comply with all applicable provisions of the FSMA with respect to anything done by it in relation to the shares included in this offering in, from or otherwise involving the United Kingdom.

We have applied to have our common stock included for quotation on The Nasdaq National Market under the symbol “LUNA.”

Underwriting

The following table shows the underwriting discount and commissions to be paid to the underwriters in connection with this offering. These amounts are shown assuming both no exercise and full exercise of the over-allotment option.


	No Exercise	Full Exercise
Per share	$	$
Total to be paid by us	$	$

We estimate that the total expenses of this offering payable by us, excluding the underwriting discount and commissions, will be approximately $1.5 million. We have agreed to indemnify the underwriters against certain liabilities that may be based upon an untrue statement of material fact contained in this prospectus, including civil liabilities under the Securities Act, or to contribute to payments that the underwriters may be required to make in respect of those liabilities.

The underwriters have informed us that neither they, nor any other underwriter participating in the distribution of this offering, will make sales of our common stock offered by this prospectus to accounts over which they exercise discretionary authority without the prior specific written approval of the customer.

The offering of our shares of common stock is made for delivery when and if accepted by the underwriters and subject to prior sale and to withdrawal, cancellation, or modification of this offering without notice. The underwriters reserve the right to reject an order for the purchase of shares in whole or part.

Subject to certain exceptions, we and each of our officers, directors and security holders, have agreed not to offer to sell, sell, pledge, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right, or warrant to purchase, lend, or otherwise transfer or dispose of, directly or indirectly, any shares of our common stock or any securities convertible into or exercisable or exchangeable for our common stock, or enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of our common stock, whether any transaction is to be settled by delivery of common stock or other securities, in cash or otherwise, without the prior written consent of ThinkEquity Partners LLC for a period of 180 days after the date of this prospectus. Notwithstanding the foregoing, for the purpose of allowing the underwriters to comply with NASD Rule 2711(f)(4), if (1) during the last 17 days of the initial 180-day lock-up period, we release earnings results or material news or a material event relating to us occurs or (2) prior to the expiration of the initial 180-day lock-up period, we announce that we will release earnings results during the 16-day period beginning on the last day of the initial 180-day lock-up period, then in each case the initial 180-day lock-up period will be extended until the expiration of the 18-day period beginning on the date of release of the earnings results or the occurrence of the material news or material event, as applicable.

Prior to this offering, there has been no established trading market for our common stock. The initial public offering price for the shares of our common stock offered by this prospectus was negotiated between us and the underwriters immediately prior to this offering. Factors considered in determining the initial public offering price included:

the history of, and the prospects for, the markets in which we compete;

our past and present operations;

our historical results of operations;

our prospects for future earnings;

the recent market prices of securities of generally comparable companies; and

the general condition of the securities markets at the time of this offering and other relevant factors.

The initial public offering price of our common stock may not correspond to the price at which our common stock will trade in the public market subsequent to this offering, and an active public market for our common stock may never develop or, if it does develop, continue after this offering.

101

Underwriting

To facilitate this offering, the underwriters may engage in transactions that stabilize, maintain, or otherwise affect the price of our common stock during and after this offering. Specifically, the underwriters may over-allot or otherwise create a short position in our common stock for their own account by selling more shares of our common stock than have been sold to them by us. Short sales involve the sale by the underwriters of a greater number of shares than they are required to purchase in this offering. “Covered” short sales are sales made in an amount not greater than the underwriters’ option to purchase additional shares from us in this offering. The underwriters may close out any covered short position by either exercising their option to purchase additional shares or purchasing shares in the open market. In determining the source of shares to close out the covered short position, the underwriters will consider, among other things, the price of shares available for purchase in the open market as compared to the price at which they may purchase shares through the over-allotment option. “Naked” short sales are sales in excess of this option. The underwriters must close out any naked short position by purchasing shares in the open market. A naked short position is more likely to be created if the underwriters are concerned that there may be downward pressure on the price of our common stock in the open market after pricing that could adversely affect investors who purchase in this offering.

In addition, the underwriters may stabilize or maintain the price of our common stock by bidding for or purchasing shares of our common stock in the open market and may impose penalty bids. If penalty bids are imposed, selling concessions allowed to syndicate members or other broker-dealers participating in this offering are reclaimed if shares of our common stock previously distributed in this offering are repurchased, whether in connection with stabilization transactions or otherwise. The effect of these transactions may be to stabilize or maintain the market price of our common stock at a level above that which might otherwise prevail in the open market. The imposition of a penalty bid may also affect the price of our common stock to the extent that it discourages resales of our common stock. The magnitude or effect of any stabilization or other transactions is uncertain. These transactions may be effected on The Nasdaq National Market or otherwise and, if commenced, may be discontinued at any time.

Other than in connection with this offering, the underwriters have not performed investment banking and advisory services for us. The underwriters may, from time to time, engage in transactions with and perform services for us in the ordinary course of their business.

A prospectus in electronic format may be made available on the Internet sites or through other online services maintained by the underwriters participating in this offering or by their affiliates. In those cases, prospective investors may view offering terms and this prospectus online and, depending upon the underwriter, prospective investors may be allowed to place orders online or through their financial advisor. The underwriters may agree with us to allocate a specific number of shares for sale to online brokerage account holders. Any such allocation for online distributions will be made by the underwriters on the same basis as other allocations.

Other than this prospectus in electronic format, the information on any underwriter’s website and any information contained in any other website maintained by the underwriters is not part of this prospectus or the registration statement of which the prospectus forms a part, has not been approved or endorsed by us or the underwriters in its capacity as underwriter and should not be relied upon by investors.

Report of independent registered public accounting firm

Board of Directors and Shareholders

Luna Innovations Incorporated and Subsidiaries

We have audited the accompanying consolidated balance sheets of Luna Innovations Incorporated and Subsidiaries (the Company) as of December 31, 2004 and 2005, and the related consolidated statements of operations, changes in stockholders’ equity and cash flows for each year of the three years in the period ended December 31, 2005. These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement. The Company is not required to have, nor were we engaged to perform an audit of its internal control over financial reporting. Our audits include consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the consolidated financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the consolidated financial position of Luna Innovations Incorporated and Subsidiaries as of December 31, 2004 and 2005, and the consolidated results of its operations and its cash flows for each of the three years in the period ended December 31, 2005, in conformity with accounting principles generally accepted in the United States of America.

Notes to consolidated financial statements

1.	Organization and Summary of Significant Accounting Policies

Luna Innovations Incorporated (“Luna Innovations” ) was incorporated in the Commonwealth of Virginia in 1990 and subsequently reincorporated in the State of Delaware in April 2003. We are engaged in the research, development and commercialization of innovative technologies in the areas of molecular technology solutions and sensing solutions. We are organized into three main groups, which work closely together to turn ideas into products: our Contract Research Group, our Commercialization Strategy Group and our Products Group. We have a disciplined and integrated business model that is designed to accelerate the process of bringing new and innovative technologies to market. We identify technology that can fulfill identified market needs. We then take these solutions from the applied research stage through commercialization.

Unaudited Interim Financial Information

The accompanying unaudited consolidated financial statements as of March 31, 2006 and for the three months ended March 31, 2005 and 2006 have been prepared in accordance with accounting principles generally accepted in the United States (US GAAP) and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by US GAAP for audited financial statements. The unaudited consolidated financial statements have been prepared on the same basis as the annual financial statements and in the opinion of management, reflect all adjustments, consisting of only normal recurring accruals, considered necessary to present fairly our financial position as of March 31, 2006 and results of operations and cash flows for the three months ended March 31, 2005 and 2006. The results of the operations for the three months ended March 31, 2006 are not necessarily indicative of the results that may be expected for the year ending December 31, 2006.

Basis of Presentation and Consolidation

Our consolidated financial statements are prepared in accordance with US GAAP and include our accounts, our wholly owned subsidiaries and other entities in which we have a controlling financial interest. We consolidate all entities in which we own more than 50% of the outstanding voting stock unless we do not control the entity. In accordance with Financial Accounting Standards Board Interpretation No. 46 revised, Consolidation of Variable Interest Entities, (FIN 46R), we also consolidate any variable interest entities for which we are deemed to be the primary beneficiary.

We use the equity method to account for our investments for which we have the ability to exercise significant influence over operating and financial policies. Consolidated net income or loss includes our share of the net earnings or losses of the investees. Our share of losses in the investees is limited to our investment and advances unless we have guaranteed certain obligations of the investee or are otherwise committed to provide financial support to such investee.

In those cases where the our investment is less than 20% and significant influence does not exist, such investments are carried at cost

We eliminate from our financial results all significant intercompany transactions.

Use of Estimates

The preparation of our consolidated financial statements in accordance with US GAAP requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses and the disclosure of contingent assets and liabilities in our consolidated financial statements and accompanying notes. Although these estimates are based on our knowledge of current events and actions we may undertake in the future, actual results may differ from such estimates and assumptions.

Luna Innovations Incorporated

Contract Research Revenues

We perform research and development for U.S. Federal government agencies, educational institutions and commercial organizations. We recognize revenues under research contracts when a contract has been executed, the contract price is fixed and determinable, delivery of services or products has occurred and collectibility of the contract price is considered probable. Revenues are earned under cost reimbursable, time and materials and fixed price contracts. Direct contract costs are expensed as incurred.

Under cost reimbursable contracts, we are reimbursed for allowable costs and paid a fixed fee. Revenues on cost reimbursable contracts are recognized as costs are incurred plus a portion of the fee earned. Revenues on time and materials contracts are recognized based on direct labor hours expended at contract billing rates plus other billable direct costs.

Revenue for fixed price research contracts that involve the delivery of services and a protoype model are recognized under the percentage of completion method in accordance with Statement of Position (SOP) 81-1, Accounting for Performance of Construction-Type and Certain Production-Type Contracts. Fixed price arrangements that involve the delivery of research reports are recognized under the proportional performance method based upon the ratio of costs incurred to total estimated cost as this method more accurately measures performance under these arrangements. Losses on contracts, if any, are recognized in the period in which they become known.

For the years ended December 31, 2003, 2004 and 2005 and the three months ended March 31, 2006, contract research revenues from agencies of the U.S. government accounted for approximately 51%, 51%, 70% and 76% respectively, of total revenues for the same period. See Note 15 for additional details concerning our relationship with major customers.

Intellectual Property License Revenues

Amounts received from third parties for licenses to our intellectual property are recognized when earned under the terms of the agreements. Revenues are recognized upon transfer of the license unless we have continuing obligations for which fair value cannot be established, in which case the revenues are recognized over the period of the obligation. If there are extended payment terms, license fee revenues are recognized as these payments become due and collectibility is probable. We consider all arrangements with payment terms extending beyond 12 months not to be fixed and determinable.

Certain of our license arrangements have also required us to enter into research and development agreements. We apply the guidance from the Emerging Issues Taskforce Consensus on Issue 00-21, Revenue Arrangements with Multiple—Deliverables (EITF 00-21). Accordingly, we will allocate our arrangement fees to the various elements based upon objective reliable evidence of fair value, if available. For those arrangements in which evidence of fair value is not available, we will defer revenues from any up-front payments and recognize them over the service period in the arrangement. Certain of these arrangements also include the payment of performance bonuses based upon the achievement of specific milestones. Generally, there are no assurances at the onset of these arrangements that the milestones will be achieved. As such, fees related to such milestones are excluded from the initial allocation of the arrangement fee in accordance with EITF 00-21 and are recognized upon achievement of the milestone provided that such fees are non-refundable and collection is probable.

Revenues derived from our arrangement with Baker Hughes Oilfield Operations, Inc. (BHI) accounted for 37% and 35% total revenues for the years ended December 31, 2003 and 2004. As discussed in Note 5 our arrangement with BHI ended in 2004.

Product Sales Revenues

Revenues from product sales are generated by the sale of commercial products and services under various sales programs to the end user and through distribution channels. We sell fiber optic sensing systems to end users for use in numerous fiber-optic based measurement applications.

F-8

Luna Innovations Incorporated

Revenues from product sales that require no ongoing obligations are recognized as revenues when shipped to the customer, title has passed and collection is reasonably assured. In transactions where a right-of-return exists, revenues are deferred until acceptance has occurred and the period for the right-of-return has lapsed. As of December 31, 2003, 2004 and 2005 and March 31, 2006, we have not entered into sales transactions where rights of return exist.

Allowance for Uncollectible Receivables

We review the status of our uncollected receivables on a regular basis. In determining the need for an allowance for uncollectible receivables, we consider our customers financial stability, past payment history and other factors that bear on the ultimate collection of such amounts. Given our favorable collection history, we have not considered it necessary to establish an allowance for uncollected receivables.

Cash Equivalents

We consider all highly liquid investments purchased with maturities of three months or less to be cash equivalents.

Fair Value of Financial Instruments

Our financial instruments include cash and cash equivalents, accounts receivables, accounts payable, a line-of-credit and accrued liabilities. The carrying amounts of financial instruments approximate fair value due to their short maturities. Additionally, the line-of-credit is subject to a variable interest rate based upon the prime rate as published by the Wall Street Journal.

Property and Equipment

Property and equipment are stated at cost less accumulated depreciation. We record depreciation using the straight-line method over the following estimated useful lives:



Equipment		3 – 7 years
Furniture and fixtures		7 years
Software		3 years
Leasehold improvements		Lesser of lease term or life of improvements

Goodwill and Intangible Assets

Intangible assets consist of goodwill and patents related to certain intellectual property that we have developed or acquired. Goodwill represents the excess of the cost of an acquired entity over the net amounts assigned to tangible and intangible assets acquired and liabilities assumed. Intangible assets are carried at cost and are amortized over a period of five years. The Company applies the provisions of Statement of Financial Accounting Standards No. 142 Goodwill and Other Intangible Assets, which requires allocating goodwill to each reporting unit and testing for impairment using a two-step approach. The Company will perform a goodwill impairment test annually or whenever an event has occurred that would more likely than not reduce the fair value of a reporting unit below its carrying amounts.

Research and Development

Research and development costs not related to contract performance are expensed as incurred. For the years ended December 31, 2003, 2004 and 2005, non-contract related research and development costs were not significant. The Company expensed $120,901 of non-contract related research and development in the three months ended March 31, 2006.

Capitalized Software Costs

The Company capitalized costs of $122,642 for the year ended December 31, 2005 and $4,229 for the three months ended March 31, 2006 related to new software products. Costs related to the development of new software products

F-9

Luna Innovations Incorporated

and significant enhancements to existing software products are expensed as incurred until technological feasibility has been established and are amortized over three years. There were no capitalized costs during the years ended December 31, 2004 and 2003.

Valuation of Long-Lived Assets

We account for long-lived assets in accordance with the provisions of Statement of Financial Accounting Standards (SFAS) No. 144, Accounting for the Impairment or Disposal of Long-Lived Assets. SFAS No. 144 requires that long-lived assets and certain identifiable intangibles be reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets is measured by comparing the carrying amount of an asset to future undiscounted net cash flows expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds their fair value. Assets to be disposed of by sale are reflected at the lower of their carrying amount or fair value less cost to sell.

Inventory

Inventory consists of finished goods and parts valued at the lower of cost (determined on the first-in, first-out basis) or market. We provide reserves for estimated obsolescence or unmarketable inventory equal to the difference between the cost of the inventory and the estimated market value based upon assumptions about future demand and market conditions.

Net Income (Loss) Per Share

We compute net income (loss) per share in accordance with SFAS No. 128, Earnings Per Share. Basic per share data is computed by dividing income (loss) available to common stockholders by the weighted average number of shares outstanding during the period. Diluted per share data is computed by dividing income (loss) available to common stockholders by the weighted average shares outstanding during the period increased to include, if dilutive, the number of additional common share equivalents that would have been outstanding if potential common shares had been issued using the treasury stock method. Diluted per share data would also include the potential common share equivalents relating to convertible securities by application of the if-converted method.

As discussed in Note 9, in connection with our proposed initial public offering the Company will effect a 1.7691911:1 reverse stock split. The following information presents the proforma effect of such split on basic and diluted net income (loss) per share.

Luna Innovations Incorporated

The effect of 2,508,548 and 4,056,465 common stock equivalents are ignored for the year ended December 31, 2005 and the three months ended March 31, 2006, as they are antidilutive to earnings per share. In addition, the conversion of the $5.0 million in senior convertible promissory notes would have been antidilutive. The effect of 19,892,454 common stock equivalents are ignored for the year ended December 31, 2003, as they are antidilutive to earnings per share.

Stock-Based Compensation

We have a stock-based compensation plan, which is described further in Note 9. Effective January 1, 2006, we adopted Financial Accounting Standards No. 123R, Share Based Payment (SFAS No. 123R) using the modified prospective transition method. Under this transition method, our financial statements for periods prior to January 1, 2006 have not been restated. However, new awards and awards modified, repurchased or cancelled after January 1, 2006 trigger compensation expense based on the fair value of the stock option as determined by the Black-Scholes option pricing model. We amortize stock-based compensation for such awards on a straight-line method over the related service period of the awards taking into account the effects of the employees’ expected exercise and post-vesting employment termination behavior.

The adoption of SFAS No. 123(R) increased the net loss by approximately $169 thousand for the three months ended March 31, 2006, as compared to what our net loss would have been if we had continued to account for share-based compensation under APB No. 25, Accounting For Stock Issued to Employees.

For the periods prior to 2006, we accounted for stock-based employee compensation arrangements using the intrinsic value method in accordance with the provisions of Accounting Principles Board Opinion (APB) No. 25, Accounting for Stock Issued to Employees and related amendments and interpretations. We complied with the disclosure provisions of Statement of Financial Accounting Standards (SFAS) No. 123, Accounting for Stock-based Compensation, as amended by SFAS No. 148, Accounting for Stock Based Compensation—Transition and Disclosure, which requires fair value recognition for employee stock-based compensation. We account for equity instruments issued to non-employees in accordance with the provisions of SFAS 123 and Emerging Issues Task Force (EITF) Issue No. 96-18.

Generally, we award options to employees and directors with exercise prices equal to or greater than the estimated fair value of our common stock on the date of grant. As more fully described in Note 9, we entered into an option exchange with our employees in September 2003 that resulted in the new option grant being considered a re-pricing in accordance with FASB Interpretation No. 44, Accounting for Certain Transactions Involving Stock Compensation (FIN 44). We apply variable plan accounting to outstanding options related to this award and measure compensation expense at each reporting period equal to an amount that reflects the change in the fair value of the underlying security.

Had compensation expense been measured under the fair value method prescribed by SFAS No. 123, our pro forma net income (loss), and pro forma net income (loss) per share would have been as follows:


	Years Ended December 31,
	2003	2004		2005
Net income (loss):
As reported	$1,132,274	$4,056,182		($1,994,057	)
Add - stock based employee compensation expense in reported net income (loss), net of related tax effects	—	39,680		133,901
Deduct - total stock based employee compensation (expense) benefit determined under Black-Scholes method for all awards, net of related tax effects	629,508	(114,553	)	(386,108	)

Pro forma net income (loss)	$1,761,782	$3,981,309		(2,246,264	)

Basic net income (loss) per common share:
As reported	$0.40	$1.40		($0.53	)
Pro forma	$0.62	$1.37		($0.60	)
Diluted net income (loss) per common share:
As reported	$0.39	$1.14		($0.53	)
Pro forma	$0.61	$1.12		($0.60	)

The $629,508 benefit in 2003 resulted from 285,665 unvested options being forfeited during the period.

The fair value of each option granted is estimated as of the grant date using the Black-Scholes option pricing model with the following assumptions:


	2003		2004		2005		2006
Risk-free interest rate range	3.52	%	3.87	%	3.9-4.6	%	4.55	%
Expected life of option-years	7		7		4.5-7		7
Expected stock price volatility	66	%	63	%	64	%	64	%
Expected dividend yield	—		—		—		—

The risk-free interest rate is based on US Treasury interest rates, the terms of which are consistent with the expected life of the stock options. Expected volatility is based upon an average volatility of comparable public companies. The expected life and estimated post employment termination behavior is based upon historical experience of homogeneous groups within our company.

During the quarter ended March 31, 2006 we granted 981,946 options to purchase shares of our common stock. We recognized $408,687 in share-based payment expense, and will recognize $5,954,604 over the remaining requisite service period.

Advertising

We charge the cost of advertising to expense as incurred. Such amounts have not been significant to our operations.

Income Taxes

We account for income taxes using the liability method. Deferred tax assets or liabilities are determined based on the difference between the financial statement and tax basis of assets and liabilities as measured by the enacted tax rates,

F-12

Luna Innovations Incorporated

which will be in effect when the differences reverse. A valuation allowance against net deferred assets is provided unless we conclude it is more likely than not that the deferred tax assets will be realized.

Recent Accounting Pronouncements

In November 2004, the FASB issued SFAS No. 151, Inventory Costs, which is an amendment of ARB No. 43 Inventory Pricing, to clarify the accounting for abnormal amounts of idle facility expense, freight, handling costs and wasted material (spoilage). This statement is effective for inventory costs incurred during fiscal year beginning after June 15, 2005. We do not believe that the effect of SFAS No. 151 will have a significant effect on our consolidated financial statements.

In May 2005, the FASB issued SFAS No. 154, Accounting Changes and Error Corrections, which replaces APB Opinion No. 20, Accounting Changes and SFAS No. 3, Reporting Accounting Changes in Interim Financial Statement. SFAS No. 154 requires that a voluntary change in accounting principle be applied retrospectively with all prior period financial statements presented on the new accounting principle. SFAS No. 154 also requires that a change in method of depreciating or amortizing a long-lived non-financial asset be accounted for prospectively as a change in estimate, and correction of errors in previously issued financial statements should be termed a “restatement.” SFAS No. 154 is effective for accounting changes and correction of errors made in fiscal years beginning after December 15, 2005. The adoption of SFAS No. 154 is not expected to have a material impact on our consolidated financial statements.

Reclassifications

Certain amounts in prior years have been reclassified to conform to the current year presentation.

5.	Investment in Affiliates

We had investments in two affiliates, Luna Technologies, Inc. (“Luna Technologies”) and Luna Energy, LLC (“Luna Energy”), which were accounted for using the equity method of accounting. As discussed in Note 1, our consolidated statements of operations includes our share of net earnings or losses of these companies to the extent of investments in and advances to such companies.

Luna Technologies

Luna Technologies, formerly a wholly-owned subsidiary until 2000, is engaged in the development and production of optical fiber test equipment and data acquisition systems. In fiscal year 2000, the Board of Directors of Luna Technologies approved a plan to spin-off Luna Technologies and raise additional equity financing in order for management to more fully execute Luna Technologies’ business plan. We retained a minority interest in Luna Technologies of approximately 23.0% subsequent to the spin-off. Between December 2000 and March 2003, Luna Technologies had received additional equity financing from non-affiliated investors which diluted our ownership percentage to approximately 7.0%. As our Chief Executive Officer and certain members of management maintained representation at the board level, allowing us to exercise significant influence over the operations of Luna Technologies. We accounted for our interest under the equity method during 2003 and 2004 and for the nine month period ended September 30, 2005.

Our share of losses in Luna Technologies for the years ended December 31, 2003, 2004, and for the nine months ended September 30, 2005 were $150,271, $58,904 and $0, respectively. We also recognized $32,000, $3,000 and $13,500 in revenues from Luna Technologies for various administrative and consulting services in these periods.

Net loss	(2,372,027	)	(959,632	)	(390,239)

On September 30, 2005, we entered into an Agreement and Plan of Merger with Luna Technologies to acquire 100.0% of its outstanding capital stock through an exchange of our Class B common stock. We exchanged 582,884 of Class B common stock valued at $1.63 per share or $948,735 as determined by a third party appraisal firm, for all of the issued and outstanding shares of common and preferred stock of Luna Technology. An additional 109,365 shares of Class B common stock were placed in escrow and are issuable upon achievement of certain conditions as defined in the agreement. On December 30, 2005, 41,634 shares of Class B common stock valued at approximately $68,000 were released from escrow. Additionally, we exchanged 2,035 warrants with an aggregate value of approximately $3,300 and incurred direct costs of approximately $81,000 to arrive at an initial purchase price of approximately $1,101,000.

Luna Technologies produces test and measurement equipment which monitor the integrity of fiber optic network components and subassemblies. The acquisition of Luna Technologies will enable us to expand our sale of fiber optic testing equipment beyond the telecommunications industry into avionics, defense and academic research laboratories.

This transaction was accounted for as a purchase business combination in accordance with SFAS No. 141 Business Combinations. As such, the net assets acquired were recorded at fair value. The results of operations for Luna Technologies have been included in the accompanying statement of operations from the acquisition date, September 30, 2005, through December 31, 2005.

The following table summarizes the estimated fair value of assets and liabilities assumed at the acquisition date:



	September 30, 2005
Current assets	$1,343,341
Property and equipment, net	286,134
Other assets	4,804
Intangible assets	166,726

Intangible assets acquired in the transaction relate primarily to intellectual property rights which will be amortized over an estimated life of 5 years.

The following unaudited pro forma combined condensed statements of operations set forth the consolidated results of our operations for the years ended December 31, 2004 and December 31, 2005 as if the above described acquisition of Luna Technologies had occurred at the beginning of each period presented. This unaudited pro forma information does not purport to be indicative of the actual results that would actually have occurred if the combination had been in effect for the years ended December 31, 2004 and December 31, 2005.

Diluted earnings per share	$0.87	$ (0.65)

Luna Energy

We formed Luna Energy on February 12, 2002, for the purpose of transferring certain intellectual property rights related to technology to be used in the oil and gas industry. On February 19, 2002, we entered into a Purchase and Sale agreement with a subsidiary of Baker Hughes Oilfields Operations, Inc. (BHI) for the purchase of a 40% interest in Luna Energy. BHI paid us an up-front payment of $10 million for the 40% equity interest as well as licensing rights to use the intellectual property transferred to Luna Energy. In connection with this agreement, we were also required to enter into a Research and Development Agreement with Luna Energy for the development of certain new technology for the benefit of BHI. BHI committed to pay us an additional $8 million upon achievement of certain milestones which were tied to the development of the new technology. Additionally, BHI committed to provide Luna Energy with $12 million in financing over an estimated collaboration period of three years.

As there was no objective and reliable evidence of fair value for deliverables in this arrangement, consistent with the revenue recognition provisions of Staff Accounting Bulletin No. 104 Revenue Recognition and the multi-element arrangement provisions of EITF 00-21, the proceeds from the $10 million payment were recognized ratably over the expected three year collaboration period as license revenues.

As previously discussed, BHI agreed to provide substantially all of the working capital required to fund Luna Energy’s operations for three years. Additionally, in accordance with Luna Energy’s Amended and Restated LLC agreement, BHI was provided certain approval rights which gave them substantive participation in the operations of Luna Energy. These rights included, but were not limited to, approval over the adoption or amendment of annual and period operating and capital budgets, approval over any single material expenditure by Luna Energy in excess of $10,000, approval over any action by Luna Energy to cease the operations of Luna Energy or to change its business focus, and approval over the election or re-election of officers of Luna Energy. Accordingly, consistent with the provisions of EITF Issue No. 96-16, Investor’s Accounting for an Investee when the Investor Has a Majority of the Voting Interest but the Minority Shareholder or Shareholder Have Certain Approval or Veto Rights, we did not consolidate Luna Energy but accounted for our interest under the equity method. We were not required to provide any capital financing to Luna Energy from inception through the three-year collaboration period, nor was there any carrying value for the intellectual property transferred to Luna Energy. Therefore, we had no basis to record losses from Luna Energy until 2004 when we advanced it $198,000. Luna Energy’s operating results did not have a material effect on our financial position or our results of operations. As such, condensed financial information on Luna Energy has not been presented.

In December 2004, BHI acquired all of our remaining equity interest in Luna Energy for a non-refundable payment of $990,000. Such amount was recognized as revenue at that date as we had no further obligation to Luna Energy or BHI.

Luna Innovations Incorporated

In addition to our licensing and development arrangement, we also performed subcontract services on certain research contracts for Luna Energy. Total revenues earned from such contracts for the years ended December 31, 2003 and 2004 were $628,050 and 176,802, respectively.

7.	Debt Agreements

Working Capital Facility

We entered into a line of credit agreement with First National Bank (FNB) in December 2001. This agreement, as amended, enabled us to borrow up to $3,000,000, subject to an eligible borrowing base, with interest payable monthly based upon the Wall Street Journal prime rate (5.0% at December 31, 2004). The line of credit is collateralized by a blanket interest in our assets and is subject to certain financial covenants.

We received a modified commitment for renewal of the line of credit in May 2005. Under the May 2005 commitment, we may draw up to $2,500,000 for working capital needs. Interest accrues on any outstanding balance at the Wall Street Journal prime rate (7.25% at December 31, 2005). Any outstanding principal balance is payable in full on demand or at maturity, May 30, 2006. Outstanding borrowings on the line of credit were $1,500,000 at December 31, 2004. There were no outstanding borrowings for the periods ended December 31, 2005 and March 31, 2006. At December 31, 2005, we were not in compliance with the minimum interest coverage covenant of our working capital facility. We requested and received a waiver from FNB.

Milestone Credit Facility

In connection with the BHI transaction discussed in Note 5, we entered into a “Milestone” working capital line of credit with FNB on May 16, 2003 for $1,500,000. Interest was payable monthly at the Wall Street Journal prime rate plus 3.0%. Advances under the line of credit were governed by us providing FNB written evidence of BHI’s acceptance and approval of payment for milestone payments under the contract with BHI. In connection with acceptance and approval for Milestone 3, we were able to borrow $1,500,000 against the line of credit. The line of credit was collateralized by a blanket interest in our assets, as well as 40.0% of the payments for Milestones 3 and 4 under the Purchase and Sale Agreement. Additionally, the line of credit was guaranteed by an officer and stockholder and was subject to certain financial covenants. The line of credit expired on March 15, 2004 and was not renewed.

Virginia Tech Foundation Note

In connection with the Luna Technologies acquisition discussed in Note 5, the Company assumed a promissory note due to the Virginia Tech Foundation for $214,955. The principal amount is due on January 31, 2007. Interest is payable

Income tax expense (benefit)	$885,882		$128,234		(557,252	)

Realization of deferred income tax assets is dependent upon sufficient future taxable income during the period that deductible temporary differences are expected to be available to reduce taxable income. In assessing the realizability of deferred tax assets, we consider whether it is more likely than not, that some portion, or all of the deferred tax asset will be realized. We consider scheduled reversals of deferred tax liabilities, projected future taxable income, and tax planning strategies that can be implemented by us in making this assessment of the realizability of such assets. We have net operating loss carryforward available at December 31, 2005 of approximately $3.0 million that expire at varying dates through 2025. We have recorded a refundable income tax receivable, of approximately $400 thousand, representing net operating losses that we plan to carry back to recover income taxes previously paid. This results in remaining net operating loss carryforwards that we anticipate using in the future of approximately $800 thousand. The Company also has R&D tax credits of approximately $1.3 million which expire at varying dates through 2025.

A tax benefit of $600,000 was recorded at December 31, 2005 and March 31, 2006, based upon management’s assessment that more likely than not the benefit will be realized in future periods.

9.	Stockholders’ Equity

Stock split

On September 22, 2003, we effected a 58:1 stock split in the form of a stock dividend on the Class A Common Stock. All prior period common stock and applicable share and per share amounts have been retroactively adjusted to reflect the stock split.

Reverse Stock split

Upon effectiveness of our initial public offering, we will effect a 1.7691911:1 reverse stock split of our common stock. All applicable share and per share amounts in the financial statements give proforma effect to such split.

Luna Innovations Incorporated

Redeemable Class B Common Stock

In connection with our acquisition of Luna Technologies on September 30, 2005, we gave the shareholders of Luna Technologies a right to put 310,253 of their shares of Class B Common Stock back to us in the event we are unsuccessful in completing an initial public offering of our common stock by December 31, 2006. Such shares have been classified as Redeemable Class B Common Stock on our December 31, 2005 consolidated balance sheet.

Warrants

Warrants to purchase 103,508 shares of our Class B Common Stock for $0.001 per share were exercised in November 2005.

In February 2006, we issued 57,542 warrants for Class B Common Stock at an exercise price of $1.77 per share to former Luna Technologies shareholders to prevent dilution by a concurrent stock option grant. The warrants were valued using a Black-Scholes option pricing model with the following assumptions: risk-free rate of 4.55%, expected volatility of 64%, and an expected life of 10 years, which equaled the contractual term. The aggregate fair value of the warrant was $418,074, and this amount has been recorded as additional purchase price for the Luna Technologies acquisition.

Upon the completion of our initial public offering all of the outstanding shares of Class A Common Stock, Class B Common Stock and Class C Common Stock will convert into one class of common stock on a one-for-one basis.

Incentive Stock Option Plan

On August 20, 1999, we adopted the Luna Innovations Incorporated Stock Purchase Plan (the 1999 Plan) which permitted our Board of Directors to grant options to officers, directors and employees of our Company. There was no pre-established number of shares of common stock reserved for issuance under this plan. Options granted under the 1999 Plan generally had a life of 5 years and an exercise price equal to the estimated fair value of the Company as determined by the Board of Directors.

In connection with our reincorporation in April 2003, we adopted the Luna Innovations Incorporated 2003 Stock Plan (the 2003 Plan). Under the 2003 Plan, our Board of Directors is authorized to grant both incentive and nonstatutory stock options to employees, directors and consultants of our Company to purchase Class B shares of Common Stock. Options generally have a life of 10 years and exercise price equal to or greater than the fair market value of the Class B Common Stock as determined by the Board of Directors. A total of 5,000,000 shares of Class B Common Stock were reserved for issuance under the 2003 Plan. On March 16, 2004, our Board of Directors increased the number of shares reserved under the Plan to 8,000,000. The expiration date of the options cannot be more than 10 years from date of grant. A total of 5,757,420 and 4,024,446 were available for future grant as of December 31, 2004 and 2005, respectively.

On February 4, 2006, our Board of Directors increased the number of shares reserved under the 2003 Plan to 9,715,000. A total of 4,888,690 are available for future grant as of March 31, 2006.

In August 2003, our Board of Directors authorized an option exchange program expiring on September 19, 2003 whereby option holders of Class A Common Stock issued under the 1999 plan were given the opportunity to exchange their options for options to purchase Class B Common Stock on a one for one basis. The new option grants were immediately vested on the date of exchange, September 29, 2003, had an exercise price of $0.35 and a life of 10 years from the date of grant. Upon completion of the option exchange program, the 1999 plan was terminated.

All of the outstanding options from the 1999 Plan had exercise prices in excess of the fair value of our Class A Common Stock as of the date of the exchange. As such, the option exchange was accounted for as a repricing in accordance with FIN 44. We are required to apply variable plan accounting to the replacement grant and measure compensation based on the change in fair value of the Class B Common Stock at each reporting period. A total of

F-21

Luna Innovations Incorporated

172,525 options were exchanged in connection with this transaction, of which 39,596 and 27,107 were outstanding at December 31, 2005 and March 31, 2006, respectively.

There was no non-cash stock option expense related to employee and director awards for the year ended December 31, 2003. Total non-cash stock option expense for the years ended December 31, 2004 and 2005 and the three months ended March 31, 2006 was $39,680, $133,901 and $408,687, respectively.

The following table sets forth the activity of our stock options to purchase class A and class B common stock and gives proforma effect to the reverse stock split discussed in Note 9.

As noted above, on September 22, 2003, the Company forward split its Class A common stock on a 58-to-1 basis. This stock split occurred chronologically after the exchange offer was made to exchange options to purchase shares of Class A common stock for options to purchase Class B common stock on a one-for-one basis (pre-split). As shown in the above table, the Company cancelled 28,307,794 shares of Class A common stock (863,481 shares prior to the stock splits noted above) in exchange for the option to purchase 207,454 shares of Class B common stock. Options representing the right to purchase 280,612 shares of Class A common stock held by certain founding stockholders were not exchanged and were cancelled without any compensation to the holder.

On the date of the exchange, the pre-split exercise price of the Class A common stock was $5.22 (post-split exercise price at $0.16 per share). Management determined that prior to the exchange offer, since the options to purchase

Luna Innovations Incorporated

Class A common stock exceeded its market value that it was in the best interest to effectuate the exchange offer, and offer the Class A option holders the right to receive a similar number of options to purchase Class B common shares at the new market price.

Commitments and Contingencies

Obligation Under Operating Leases

We lease our facilities in Blacksburg, Charlottesville, Danville and Hampton, Virginia under non-cancellable operating leases that expire between July 2005 and May 2009. Certain of the leases are subject to fixed escalations. We recognize rent expense on such leases on a straight-line basis over the lease term. Rent expense under these leases was approximately $406,000, $560,000 and $600,000 for the years ended December 31, 2003, 2004 and 2005, respectively.

Minimum future rentals, as of December 31, 2005, under the aforementioned operating leases for each of the next five periods ending are:

New Facility Lease

We have entered into an agreement with Carilion Medical Center to lease 20,000 square feet of office space at the Riverside Centre in Roanoke, Virginia that will serve as our headquarters. The landlord of this property, Carilion

F-23

Luna Innovations Incorporated

Medical Center, is an affiliate of Carilion Health System, currently our second largest stockholder. Dr. Edward Murphy, Chairman and Chief Executive Officer of Carilion Health System became a member of our board of directors in connection with the investment of $7.0 million by Carilion Health System in August 2005. The lease has a five year term commencing on the later of September 1, 2006 or the date Carilion Medical Center provides us with a certificate of occupancy. Base rent will be $480,000 per year, subject to annual escalations of two percent. As of December 31, 2005, we had not received a certificate of occupancy.

Obligation Under Capital Leases

We are obligated under capital leases covering certain equipment and software that expire at various dates during the next four years. Minimum lease payments as of December 31, 2005 were as follows:


2006		$105,947

2007		91,635

Governor’s Opportunity Fund

In March 2004, we received a $900,000 grant (the “Grant”) from the City of Danville, Virginia (the “City”) to be used for the expansion of economic and commercial growth within the City. Specifically, $450,000 of the grant will be used to offset certain capital expenditures for leasehold improvements being made at our Danville facility, and the remaining $450,000 is to be used for our creation of new jobs upon satisfaction of the conditions described below.

The Grant stipulates that we must make estimated capital expenditures of at least $6,409,000 and create 54 new full time jobs at our Danville facility, at an average wage of at least $39,000 plus benefits within 30 months of the award, and then maintain such employment levels for an additional 30 months. We could be required to repay the grant funds on a pro-rata basis should we fail to satisfy the conditions stipulated in this agreement by September 25, 2006 at the

F-24

Luna Innovations Incorporated

earliest. As such, since we have not yet met the stipulations of the grant, we have included the $900 thousand in deferred revenue and other credits in the accompanying consolidated balance sheets as of December 31, 2004 and 2005.

Purchase Order

Royalty Agreement

We have licensed certain third-party technology from a vendor that provides for minimum royalties aggregating $3.5 million payable over the remaining patent terms of the underlying technology.

11.

Employee Profit Sharing Plan

We maintain a salary reduction/profit-sharing plan under provisions of Section 401(k) of the Internal Revenue Code. The plan is offered to employees who have completed three months of service with us. We contribute 50% of the salary deferral elected by each employee up to a maximum deferral of 10% of annual salary.

We may, at our option, contribute additional amounts to the plan. We contributed approximately $165 thousand, $156 thousand and $213 thousand to the plan for the years ended December 31, 2003, 2004 and 2005, respectively, and approximately $53 thousand and $60 thousand for the three months ended March 31, 2005 and 2006.

12.

Transfers of Intellectual Property

Luna i-Monitoring

We formed Luna i-Monitoring, Inc., in February 2002, to focus on the commercialization of integrated wireless telesensing systems for managing remote assets. On October 1, 2003, we, along with our individual stockholders, agreed to the terms of a share purchase and asset transfer agreement with IHS Energy Group, Inc. and for the sale of all of the issued and outstanding capital stock of Luna i-Monitoring Inc., as well as the rights, title and interest in its intellectual property. Total consideration received at closing was approximately $700,000.

Luna i-Monitoring had no substantial assets or operations from inception through the date of the sale of IHS Energy Group, Inc., but did hold the rights to intellectual property. We recorded the payment of $700,000 upon the sale of Luna i-Monitoring and intellectual property in accordance with SAB 104 since we had no further obligations to IHS Energy Group, Inc.

Biotechnology Company

On December 1, 2003, our subsidiary, Luna Analytics, entered into a license agreement with a biotechnology company granting a worldwide exclusive license for the use of certain patents and technology subject to the terms of the agreement for work in the field of life sciences research applications. We also entered into a research and development agreement with the licensee to develop additional technology. In exchange for the license rights, we were paid a one-time technology access fee of $1.0 million. The agreement also called for additional payments aggregating to $1.5 million each upon achievement of certain milestones.

Since there was no objective and reliable evidence of fair value for deliverables in this arrangement, we deferred the up-front payment of $1.0 million and were recognizing it ratably over the 10 year collaboration period. In October 2004, this biotechnology company notified us of its desire to terminate the research and development agreement. Since we had no further obligations to this biotechnology company under this arrangement, we recognized the remaining revenues upon the termination of the agreement.

13.

Litigation and Other Contingencies

We are not party to any material legal proceedings, nor are we currently aware of any threatened material proceedings. From time to time, we may become involved in litigation in relation to claims arising out of our operations in the normal course of business. While management currently believes the amount of ultimate liability, if any, with respect to these actions will not materially affect our financial position, results of operations, or liquidity, the ultimate outcome of any

F-25

Luna Innovations Incorporated

litigation is uncertain. Were an unfavorable outcome to occur, or if protracted litigation were to ensue, the impact could be material to us.

On November 9, 2004, we received a subpoena from the Department of Defense’s Office of the Inspector General covering certain government research contracts awarded to us between January 1, 1998 and November 9, 2004 to determine if we had duplicated work in our submission of project reports to the government. In connection with the investigation, the government alleged that duplication occurred in three research reports that we prepared under the contracts. We submitted a response to the Inspector General in September 2005 challenging the government’s findings. On November 15, 2005, we entered into a settlement agreement with the government and received a general release with respect to this matter in return for a payment of $165,333. Such amount has been accrued for in the December 31, 2004 and 2005 balance sheets.

We have made, and will continue to make, efforts to comply with current and future environmental laws. We anticipate that we could incur additional capital and operating costs in the future to comply with existing environmental laws and new requirements arising from new or amended statutes and regulations. In addition, because the applicable regulatory agencies have not yet promulgated final standards for some existing environmental programs, we cannot at this time reasonably estimate the cost for compliance with these additional requirements. The amount of any such compliance costs could be material. We cannot predict the impact that future regulations will impose upon our business.

14.

Carilion Transactions

In August 2005, we entered into a Class C Common Stock Financing Agreement with Carilion Health System (Carilion) whereby Carilion committed to providing approximately $15.0 million in equity financing in three tranches subject to certain conditions outlined in the agreement. Carilion purchased 1,492,032 shares of our Class C Common Stock (the first tranche) for an aggregate purchase price of $7.0 million at closing.

In connection with the agreement, we also entered into an investor rights agreement with Carilion giving them certain registration rights in the event that we are successful in completing an initial public offering of our common stock.

On December 30, 2005, we reached an agreement with Carilion to terminate the August 2005 equity Financing Agreement and enter into a new Class C Common Stock Financing Agreement (the “New Agreement”). Under the New Agreement, Carilion agreed to provide $5.0 million in exchange for five $1.0 million convertible promissory notes, and $3.0 million in exchange for 639,442 shares of Class C Common Stock, subject to certain conditions.

F-26

Luna Innovations Incorporated

The notes are convertible into Class C Common Stock at a fixed rate of $4.69159 per share. These notes accrue simple interest at a rate of 6.0% per year and are due and payable on December 30, 2009 or a later date if extended by the holders of a majority of the aggregate principal amount of the notes, absent acceleration due to an event of default. The holders of a majority of the aggregate principal amount of the notes may also extend the maturity date of these notes for one additional year by providing notice to us and may further extend the maturity date for up to an additional three consecutive one year periods if we are not eligible for or have elected not to pursue SBIR funding. After the first extension, if any, we will have the right to repay any accrued interest in cash rather than common stock. The holders of these notes have the option to convert their notes (subject to certain limitations) into shares of our common stock at maturity or upon the occurrence of certain events prior to this offering. In addition, the holders may convert their notes (subject to certain limitations) into shares of common stock if we are no longer eligible for SBIR grants or have not applied for an SBIR grant within the preceding 12 months.

In connection with the New Agreement, we amended and restated the investor rights agreement granting Carilion and certain other shareholders the rights to require us to register their shares of Common Stock for resale. Although we could be required to register shares held by these shareholders, there is no liquidated damages provision in the event such shares are not registered and the conversion of such debt can be satisfied with unregistered shares of Class C Common Stock.

15.

Relationship With Major Customers

During the years ended December 31, 2003, 2004 and 2005 and the three months ended March 31, 2006, approximately 51%, 51%, 70% and 76%, respectively, of our consolidated revenues were attributable to prime contracts with the U.S. government. In addition, during the years ended December 31, 2003, 2004 and 2005, two of our non-government customers accounted for approximately 37%, 35% and 14% of our consolidated revenues, respectively, although these customers are not expected to be an ongoing source of revenues of that amount in the future. Our revenues from these major customers are as follows:


	Year ended December 31,			Three Months Ended March 31,
	2003	2004	2005	2005	2006
U.S. Government	$8,969,004	$11,509,964	$11,471,447	$2,263,869	$3,444,636

INDEPENDENT AUDITOR’S REPORT

To the Board of Directors

Luna Technologies, Inc.

Blacksburg, Virginia

We have audited the accompanying balance sheet of Luna Technologies, Inc. as of December 31, 2004, and the related statements of operations, changes in stockholders’ equity (deficit), and cash flows for the year then ended. These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with auditing standards generally accepted in the United States. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of Luna Technologies, Inc. as of December 31, 2004, and the results of its operations and its cash flows for the year then ended in conformity with accounting principles generally accepted in the United States of America.

Notes to financial statements

(Information for the nine months ended September 30, 2004 and September 29, 2005 is unaudited)

1.	Organization and Nature of Business

Luna Technologies, Inc. (the “Company”) was originally incorporated on July 24, 1998 in the Commonwealth of Virginia as a wholly-owned subsidiary of Luna Innovations Incorporated (“Luna Innovations”). On December 11, 2000, we were reincorporated in the State of Delaware.

We develop and sell test instruments to measure the integrity of fiber optic network components and modules. Due to the nature of our products, the volume of sales transactions tends to be very low with relatively high average revenues per sale. Although we have repeat customers, we depend primarily on sales to new customers each year to maintain and increase revenues.

2.	Summary of Significant Accounting Policies

Basis of Presentation

Our audited financial statements have been prepared in accordance with accounting principles generally accepted in the United States (US GAAP). Our unaudited financial statements have been prepared in accordance with US GAAP for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required to be presented for complete financial statements. The accompanying financial statements include all adjustments (consisting only of normal recurring accruals), which are, in the opinion of our management, necessary for a fair presentation of the results for the interim periods presented. The results of operations for the period from January 1 through September 29, 2005 are not necessarily indicative of the results that may be expected for the year ended December 31, 2005.

The unaudited financial statements and related disclosures have been prepared with the presumption that users of the interim financial information have read or have access to the audited financial statements for the preceding fiscal year. Accordingly, these financial statements should be read in conjunction with the audited financial statements and the related notes included for 2004. The unaudited financial statements as of and for the nine months ended September 29, 2005 do not include the effects of the acquisition of the Company by Luna Innovations, which is discussed in Note 16.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates.

Cash and Cash Equivalents

Cash and cash equivalents consist of highly liquid investments with an original maturity of three months or less.

We maintain our cash in bank deposit accounts which, at times, may exceed federally insured limits. We have not experienced any losses in such account. We believe we are not exposed to any significant credit risk on cash and cash equivalents.

Financial Instruments

Our balance sheet includes various financial instruments (primarily cash and cash equivalents, accounts receivable, note receivable, accounts payable, accrued compensation and accrued liabilities). The fair values of these financial instruments approximate the carrying values due to their short maturities. The fair value of debt approximated its

F-33

Luna Technologies, Inc.

carrying amount as of December 31, 2004 and September 29, 2005 based on rates currently available to us for debt with similar terms and remaining maturities.

Concentration of Credit Risk

Financial instruments that potentially subject us to concentrations of credit risk consist primarily of cash and cash equivalents, accounts receivable, and notes receivable. We deposit our cash with financial institutions in the United States that we consider to be of high credit quality.

Accounts Receivable

With respect to accounts receivable and notes receivable, we perform ongoing credit evaluations of our customers, generally do not require collateral, and maintain an allowance for doubtful accounts based on historical experience and management’s expectations.

Inventories

Inventory consists of component parts, work-in-progress, and finished goods. Inventory is stated at the lower of cost, determined on the first-in, first-out (FIFO) basis, or market.

Property and Equipment

Property and equipment are recorded at cost. Depreciation and amortization are calculated on the straight-line method over the following estimated useful lives of the assets:



Computer and sale demo equipment		3 – 7 years
Furniture and equipment		3 – 7 years
Software		3 – 7 years
Leasehold improvements		Lesser of lease term or life of improvements
Vehicles		5 years

Depreciation expense for the year ended December 31, 2004 and the nine months ended September 30, 2004 and September 29, 2005 was $252,933, $171,826 and $111,751, respectively.

Certain equipment held under capital leases is classified as property and equipment and is amortized using the straight-line method over the term of the lease. The related obligations are recorded as liabilities. Lease amortization expense is included in depreciation and amortization expense. Maintenance and repairs are charged to expense as incurred.

Impairment of Long-Lived Assets

We evaluate our long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of any asset to future net undiscounted cash flows expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured by future discounted cash flows compared to the carrying amount of the assets. No such indicators existed as of December 31, 2004 and as of September 29, 2005.

F-34

Luna Technologies, Inc.

Revenue Recognition

Revenues are derived from product sales. We recognize revenues when all the following criteria are met: (i) persuasive evidence of an arrangement exists, (ii) delivery has occurred, (iii) the fee is fixed or determinable, and (iv) collectibility is probable.

We accrue for warranty costs, sales returns and other allowances on our best estimate of costs that will be incurred on the delivered product.

Stock-Based Compensation

We have a stock-based employee compensation plan, which is more fully described in Note 11. We account for stock-based employee compensation arrangements in accordance with Accounting Principles Board Opinion No. 25, Accounting for Stock Issued to Employees (APB 25), and comply with the disclosure provisions of Statement of Financial Accounting Standards No. 123, Accounting for Stock-Based Compensation (SFAS No. 123). Awards under our current plan vest over a period of up to five years. We account for equity instruments issued to nonemployees in accordance with SFAS No. 123 and EITF 96-18, Accounting for Equity Instruments that are Issued to Others than Employees for Acquiring, or in Conjunction with Selling, Goods or Services. For the year ended December 31, 2004 and the nine months ended September 30, 2004 and September 29, 2005, applying the value-based method under SFAS 123 to all outstanding and unvested options would have not have a material impact on the net loss as reported by us.

The fair value of each option grant is estimated on the date of grant using the Minimum Value option-pricing model with the following assumptions: dividend yield of 0.00%; riskfree interest rate of 5.00%; and an expected life of five years. In determining the value of the options, management also considers the fundamentals of Luna Technologies, including earnings performance, liquidation performances, and dilution of common stock by preferred stock conversion rights. The effect of applying SFAS No. 123 to the calculation of the pro forma net loss as stated above is not necessarily representative of the effects on reported net loss for future years due to, among other things, (1) the vesting period of the stock options and (2) the fair market value of additional stock options in future years.

In December 2004, the FASB issued SFAS No. 123 (revised 2004), Share-Based Payment, which is a revision of SFAS No. 123, Accounting for Stock-Based Compensation (SFAS No. 123R). SFAS No. 123R supersedes APB Opinion No. 25, Accounting for Stock Issued to Employees, and amends SFAS No. 95, Statement of Cash Flows. Generally, the approach in SFAS No. 123R is similar to the approach described in SFAS No. 123. However, SFAS No. 123R requires all share-based payments to employees, including grants of employee stock options, to be recognized in the income statement based on their fair values. Pro forma disclosure is no longer an alternative. Publicly traded companies are required to adopt SFAS No. 123R on January 1, 2006.

On September 30, 2005, all outstanding options were cancelled in conjunction with the acquisition by Luna Innovations as discussed in Note 16.

Advertising Costs

We expense all advertising costs as incurred. We incurred approximately $44,000, $13,325 and $73,490 of advertising expense during the year ended December 31, 2004 and the nine months ended September 30, 2004 and September 29, 2005, respectively.

Research and Development Costs

Expenditures relating to the development of new products and processes, including significant improvements to existing products, are expensed as incurred. Software development costs are subject to capitalization beginning when a product’s technological feasibility has been established and ending when a product is available for release to customers. Our products are released soon after technological feasibility has been established. As a result, the costs subsequent to achieving technological feasibility have been insignificant and all software development costs have been expensed.

F-35

Luna Technologies, Inc.

Income Taxes

We provide for income taxes in accordance with the liability method required by Statement of Financial Accounting Standards No. 109, Accounting for Income Taxes (SFAS 109). Under this method, deferred tax assets and liabilities are determined based on differences between financial reporting and tax bases of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse.

3.	Inventories

Inventories consist of the following at:


	December 31, 2004		September 29, 2005
Finished goods	$30,000		$39,272
Raw materials	76,494		384,473
Work-in-process	116,228		10,198

	222,722		433,943
Obsolescence reserve	(10,000	)	(11,702	)

	$212,722		$422,241

4.	Note Receivable

As partial payment for a product sale, we accepted a promissory note payable for 36 equal installments of $4,290 beginning on August 1, 2002. The note bears interest at a rate of 6.5% per annum, with the product as collateral. The revenues on the remaining balance of the note receivable were $79,671 as of December 31, 2003. We recognized the remaining revenues related to the sale in 2004 because the maker of the note was purchased by a third party and our management believes there is minimal risk of default on the note and repossession of the equipment.

5.	Property and Equipment

Property and equipment, at cost, including equipment under capital lease obligations, consist of the following at December 31, 2004:



Computer and sales demo equipment		$53,309
Furniture and equipment		801,146
Computer software		270,154
Leasehold improvements		43,020

Luna Technologies, Inc.

Debt

On August 31, 2001, we entered into an equipment term note (the “Term Note”) with a financial institution that provides for borrowings up to $800,000. At December 31, 2004, no balance was outstanding under the Term Note.

In conjunction with the execution of the Term Note, we issued warrants to purchase 88,642 shares of Series A Preferred Stock at $0.7222 per share. The warrants were fully vested upon issuance and expire on August 31, 2007. The fair value of the warrants was calculated using the Black-Scholes option-pricing model using the following assumptions: (a) 73% expected volatility; (b) 44 month expected life; (c) 0% expected dividend yield; and (d) 5.0% risk-free interest rate. We recorded deferred financing costs of $51,803, of which $46,094 related to the fair value of the warrants issued to the financial institution. The deferred financing costs are being amortized to interest expense using the effective interest method over the period the related debt is expected to be outstanding (three years). During the year ended December 31, 2004, we recognized additional interest expense of $15,828.

On August 31, 2003, we refinanced two previous loans totaling $214,953 with an affiliated organization in return for an interest only note payable beginning September 30, 2003 and bearing interest of 5% per annum. The note calls for 23 interest payments of $897, with a balloon payment of $214,953 due on August 1, 2005. At December 31, 2004, $214,953 was outstanding under this term note. In April 2005, the maker of the note extended the term until July 31, 2007. Consequently, the balance of the note is presented as a non-current liability.

On September 1, 2002, we agreed to borrow an aggregate of $105,060 from an affiliated organization in return for (i) a promissory note and (ii) warrants to purchase 36,364 shares of Series A Preferred Stock at $0.7222 per share. The warrants were fully vested upon issuance and expire on September 1, 2007. The fair value of the warrants was calculated using the Black-Scholes option-pricing model using the following assumptions: (a) 77% expected volatility; (b) five-year expected life; (c) 0% expected dividend yield; and (d) 5.0% risk-free interest rate. We recorded deferred financing costs of $26,182 related to the fair value of the warrants issued to the financial institution. The deferred financing costs are being amortized to interest expense using the effective interest method over the original four year term of the note. During the year ended December 31, 2004, we recognized additional interest expense of $5,236 per year. This note was refinanced as part of the interest only loan described above.

Annual maturities of all long-term debt are as follows:

Year ended December 31:



2005		$ —
2006		—
2007		214,953

		$214,953

7.	Related Party Transactions

During the year ended December 31, 2004, we incurred approximately $1,966 of administrative fees paid to a stockholder.

During the year ended December 31, 2004, we sold products and services to the same stockholder valued at approximately $46,178.

Luna Technologies, Inc.

8.	Income Taxes

Significant components of the provision for (benefit from) income taxes attributable to operations consist of the following at December 31, 2004:



Current	$—
Deferred	(316,637	)
Valuation allowance	316,637

	$—

The difference between the tax provision and the amount that would be computed by applying the statutory federal income tax rate to income before taxes is primarily attributable to the valuation allowance for deferred tax assets.

Temporary differences and carryforwards, which give rise to a significant portion of deferred tax assets and liabilities, are as follows at December 31, 2004:



Deferred tax assets:
Net operating loss carryforwards	$3,937,451
Depreciation	(18,098	)
Accrued other	34,706
Valuation allowance	(3,954,059	)

Net deferred tax assets	$—

We have net operating loss carryforwards for federal income tax purposes of approximately $10,200,000, which expire, if unused, from the year 2019 through the year 2024. The timing and manner in which this net operating loss carryforward may be utilized in any year by us may be limited to our ability to generate future earnings and also be limited by certain provisions of the U.S. tax code. Realization of total deferred tax assets is contingent upon the generation of future taxable income. Due to the uncertainty of realization of these tax benefits, we have provided a valuation allowance for the full amount of its deferred tax assets.

9.	Lease Commitments

We lease office facilities and office equipment under operating lease agreements. Rent expense for the year ended December 31, 2004 was approximately $96,400.

Future minimum rental payments associated with non-cancelable lease obligations are as follows at December 31, 2004:



2005		$104,431
2006		104,431
2007		8,703

		$217,565

Redeemable Preferred Stock

Series A

On December 22, 2000, we entered into the Series A Preferred Stock Purchase Agreement (Purchase Agreement). The sale of Series A Preferred Stock was effected in three closings occurring during 2001. The first closing occurred simultaneous with the execution of the Purchase Agreement whereby we issued 6,923,290 shares of Series A Preferred Stock at $0.7222 per share for gross proceeds of $5 million, less offering costs of $76,783. The second closing of the Purchase Agreement was executed on March 19, 2001, whereby we issued 1,841,591 shares of Series A Preferred Stock at $0.7222 per share for gross proceeds of $1,329,997, less offering costs of $14,630. The third closing of the Purchase Agreement was executed on October 10, 2001, whereby we issued 3,615,343 shares of Series A Preferred Stock at $0.7222 for gross proceeds of $2,611,001, less offering costs of $8,401.

The holders of Series A Preferred Stock are entitled to receive, when declared by our Board of Directors, cumulative dividends, accruing from the date of issuance at a rate of 8% per annum on each outstanding share of Series A Preferred Stock.

Each share of the Series A Preferred Stock is convertible into one share of common stock at the election of the holder, subject to certain anti-dilutive provisions. Conversions are automatic in the event of public offering of common stock in which the net proceeds to us are at least $25 million or upon the closing of an acquisition or asset transfer resulting in gross cash proceeds of at least $75.0 million. The holders of Series A Preferred Stock are entitled to one vote per share. Furthermore, the holders of Series A Preferred Stock are entitled to elect a certain number of members to the Board of Directors as well as vote on significant matters affecting us. In addition, the holders of Series A Preferred Stock have a liquidation preference in the event of our dissolution. The liquidation price is equal to the sum of the original issuance price per share of Series A Preferred Stock, plus any accrued and unpaid dividends. Holders of Series A Preferred Stock are entitled to redemption any time after the fifth anniversary of original issuance of the Series A Preferred Stock in two equal annual installments. The redemption price is equal to the sum of the original issuance price per share of Series A Preferred Stock, plus any accrued and unpaid dividends.

The difference between the redemption price of the Series A Preferred Stock and the carrying value of the Series A Preferred Stock is being accreted over the period from the issuance date to the redemption date using the effective-interest method.

In conjunction with the issuance of Series B shares described below, certain holders of common stock were entitled to convert shares of common stock to Series A Preferred Stock. The shares converted and the related carrying values of the common and preferred shares are as follows:

Series A-1

Pursuant to the issue of Series B Preferred Stock described below, we authorized 13,000,000 shares of Series A-1 Preferred Stock to convert the Series A Preferred Stock for stockholders who opted not to participate in the Series B Preferred Stock issue. Series A-1 Preferred Stock has the same dividend, redemption, and conversion features as Series A Preferred Stock, but is subordinated in liquidation. 214,631 shares of Series A Preferred Stock were converted to Series A-1 Preferred Stock during 2003.

F-39

Luna Technologies, Inc.

Series B

On March 31, 2003, we entered into the Series B Preferred Stock Purchase Agreement (Purchase Agreement). The sale of Series B Preferred Stock was effected in two closings. The first closing occurred simultaneous with the execution of the Purchase Agreement whereby we issued 26,618,308 shares of Series B Preferred Stock at $0.055 per share for net proceeds of $1,464,007. The second closing occurred during 2004 whereby we issued 26,209,218 additional shares of Series B Preferred Stock at $0.055 per share for net proceeds of $1,441,481.

The holders of Series B Preferred Stock are entitled to receive, when declared by our Board of Directors, cumulative dividends, accruing from the date of issuance at a rate of 8% per annum on each outstanding share of Series B Preferred Stock.

Each share of the Series B Preferred Stock is convertible into one share of common stock at the election of the holder, subject to certain anti-dilutive provisions. Conversions are automatic in the event of public offering of common stock in which the net proceeds to us are at least $25 million or upon the closing of an acquisition or asset transfer resulting in gross cash proceeds of at least $75 million. The holders of Series B Preferred Stock are entitled to one vote per share. Furthermore, the holders of Series B Preferred Stock are entitled to elect a certain number of members to the Board of Directors as well as vote on significant matters affecting us. In addition, the holders of Series B Preferred Stock have a liquidation preference in the event of our dissolution. The liquidation price is equal to the sum of the original issuance price per share of Series B Preferred Stock, plus any accrued and unpaid dividends. Holders of Series B Preferred Stock are entitled to redemption any time after the fifth anniversary of original issuance of the Series B Preferred Stock in two equal annual installments. The redemption price is equal to the sum of the original issuance price per share of Series B Preferred Stock, plus any accrued and unpaid dividends.

The difference between the redemption price of the Series B Preferred Stock and the carrying value of the Series B Preferred Stock is being accreted over the period from the issuance date to the redemption date using the effective-interest method.

11.

Stockholders’ Equity (Deficit)

Common Stock

We have authorized 160 million shares of common stock with a $0.001 par value. Dividends may be declared and paid on the common stock, subject in all cases to the rights and preferences of the holders of Series A and Series B Preferred Stock and to authorization by the Board of Directors. In the event of liquidation or winding up of Luna Technologies and after the payment of all preferential amounts required to be paid to the holders of Series A and Series B Preferred Stock, any remaining funds shall be distributed among the holders of the issued and outstanding common stock.

Stock Options

On September 7, 2000, we adopted the Luna Technologies, Inc. 2000 Incentive Stock Option Plan (the Plan) to provide for the granting of stock awards, such as stock options, to employees, directors and other individuals as determined by the Board of Directors. We have reserved 9,900,000 shares of common stock under the Plan. Stock options granted under the Plan may be either incentive stock options (ISOs) as defined by the Internal Revenue Code, or nonqualified stock options. The Board of Directors determines who will receive options under the Plan and determines the vesting period, which is generally five years. Options may have a maximum term of no more than 10 years. The exercise price of ISOs granted under the Plan shall not be less than 100% of the fair market value of the common stock on the date of grant. The Board of Directors determines the exercise price of nonqualified options.

Introduction to unaudited pro forma consolidated financial statement

The unaudited pro forma consolidated statement of operations for the year ended December 31, 2005 gives effect to our acquisition of all outstanding shares of Luna Technologies, Inc. (“Luna Technologies”) as if it had occurred on January 1, 2005, combining the consolidated statement of operations of Luna Innovations Incorporated for the year ended December 31, 2005 and the unaudited statement of operations of Luna Technologies for the period from January 1 through September 29, 2005.

The unaudited pro forma consolidated balance sheet as of December 31, 2005 has not been presented because the acquisition was consummated on September 30, 2005, and the balance sheet impact of the acquisition is therefore reflected in our consolidated balance sheet as of December 31, 2005.

As described in Note 5 to the Luna Innovations audited consolidated financial statements included elsewhere herein, we acquired all of the outstanding shares of Luna Technologies that we did not already own on September 30, 2005.

The pro forma consolidated statement of operations is unaudited and does not purport to represent the consolidated results that would have been obtained had the transaction occurred at the date indicated or the results which may be obtained in the future. The unaudited pro forma consolidated statement of operations does not represent the results which may be obtained in the future because, we believe that overhead and other operating costs will not continue at the same level as a result of integration efforts and synergies related to infrastructure and distribution channels, among other factors. Therefore, the results of operations reflected in the unaudited pro forma consolidated statement of operations for the period presented are not necessarily indicative of the results of operations which may be obtained in the future.

The unaudited pro forma consolidated statement of operations should be read in conjunction with: (i) our audited consolidated financial statements included in this prospectus and (ii) the audited and unaudited financial statements of Luna Technologies included in this prospectus.

ITEM 14. Indemnification of Directors and Officers

Section 145(a) of the Delaware General Corporation Law provides that a Delaware corporation may indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of the corporation) by reason of the fact that such person is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation or enterprise, against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with such action, suit or proceeding if he or she acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had no cause to believe his or her conduct was unlawful.

Section 145(b) of the Delaware General Corporation Law provides that a Delaware corporation may indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of the corporation to procure a judgment in its favor by reason of the fact that such person acted in any of the capacities set forth above, against expenses (including attorneys’ fees) actually and reasonably incurred by such person in connection with the defense or settlement of such action or suit if he or she acted under similar standards, except that no indemnification may be made in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable to the corporation unless and only to the extent that the court in which such action or suit was brought shall determine that, despite the adjudication of liability but in view of all the circumstances of the case, such person is fairly and reasonably entitled to be indemnified for such expenses which the court shall deem proper.

Information not required in prospectus

Section 145 of the Delaware General Corporation Law further provides that: (i) to the extent that a former or present director or officer of a corporation has been successful in the defense of any action, suit or proceeding referred to in subsections (a) and (b) or in the defense of any claim, issue or matter therein, such person shall be indemnified against expenses (including attorneys’ fees) actually and reasonably incurred by him or her in connection therewith; (ii) indemnification provided for by Section 145 shall not be deemed exclusive of any other rights to which the indemnified party may be entitled; and (iii) the corporation may purchase and maintain insurance on behalf of any present or former director, officer, employee or agent of the corporation or any person who at the request of the corporation was serving in such capacity for another entity against any liability asserted against such person and incurred by him or her in any such capacity or arising out of his or her status as such, whether or not the corporation would have the power to indemnify him or her against such liabilities under Section 145.

Article X of our amended and restated certificate of incorporation and Article VIII of our proposed amended and restated certificate of incorporation provides for the indemnification of directors to the fullest extent permissible under Delaware law.

Article VI of our proposed amended and restated bylaws provides for the indemnification of officers, directors and third parties acting on our behalf if such person acted in good faith and in a manner reasonably believed to be in and not opposed to our best interest and, with respect to any criminal action or proceeding, the indemnified party had no reason to believe his or her conduct was unlawful.

We have entered into indemnification agreements with our directors, executive officers and others, in addition to indemnification provided for in our bylaws, and intend to enter into indemnification agreements with any new directors and executive officers in the future.

We have purchased and intend to maintain insurance on behalf of any person who is or was a director or officer against any loss arising from any claim asserted against him or her and incurred by him or her in any such capacity, subject to certain exclusions.

In connection with the transaction we issued to the same accredited investor a series of senior convertible promissory notes convertible into 1,065,740 shares of common stock upon the conversion of the principal amount outstanding under the convertible notes and, assuming we elect to convert all of the accrued interest on these notes into shares of common stock after these notes remain outstanding for eight years, up to an additional 511,553 shares of common stock.

The recipients of securities in each such transaction represented their intention to acquire the securities for investment only and not with a view to or for sale in connection with any distribution thereof and appropriate legends were affixed to the share certificates and warrants issued in such transactions. All recipients had adequate access, through their relationships with us, to information about us.

ITEM 16. Exhibits and Financial Statement Schedules

(a)

Exhibits.

A list of exhibits filed herewith is contained in the exhibit index that immediately precedes such exhibits and is incorporated herein by reference.

ITEM 17. Undertakings

The undersigned Registrant hereby undertakes to provide to the underwriters at the closing specified in the Underwriting Agreement certificates in such denominations and registered in such names as required by the underwriters to permit prompt delivery to each purchaser.

Insofar as indemnification by the Registrant for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the Registrant pursuant to the provisions described in Item 14 or otherwise, the Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

The undersigned Registrant hereby undertakes that:

(1)

For purposes of determining any liability under the Securities Act, the information omitted from the form of prospectus filed as part of this registration statement in reliance upon Rule 430A and contained in a form of prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities Act shall be deemed to be part of this registration statement as of the time it was declared effective.

(2)

For the purpose of determining any liability under the Securities Act, each post-effective amendment that contains a form of prospectus shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
