Business Overview

         I-trax enables better healthcare through personalized health management
programs.

         We believe  that our  personalized  disease  and  lifestyle  management
solutions  enable  organizations  to  evolve  from  fragmented  care  management
practices into a cohesive and efficient system of healthcare.  Our solutions are
fully integrated, use a single-data platform that allows all caregivers to share
records and enable our clients to provide true  coordination of care. We believe
that by facilitating  real-time  communication  between all stakeholders  within
today's complex  healthcare  system,  our solutions  reduce costs and enable the
best possible delivery of care.

         Health-e-LifeSM Program

         We  deliver  our  solutions  through  out  proprietary  Health-e-LifeSM
Program.  The  Program  is  designed  to  deliver  lifestyle,  disease  and risk
reduction interventions to an entire population by utilizing predictive science,
technology, clinical expertise and personal care coordination.

                  Science

         Our Health-e-LifeSM  Program incorporates predictive science to analyze
our clients'  medical  claims and pharmacy and clinical  data to predict  future
healthcare  costs. We believe this is an essential step to effective disease and
lifestyle   management.   Experts  agree  that  predictive  science  provides  a
comprehensive  advantage to health plans, employers and providers,  and leads to
cost effective medical  management and greater  profitability.  Using predictive
science,  we analyze our clients' entire  populations to accurately  predict our
clients'  future  healthcare  costs,   including  avoidable  costs,  the  health
conditions  that will  drive  those  costs and the people  within  our  clients'
populations who are at risk for those  conditions.  Armed with this information,
I-trax is able to target the most  appropriate  resources  to  achieve  the best
savings and return on investment.

                  Technology Solutions

         All  technology  components of our  Health-e-LifeSM  Program  utilize a
single data platform--Medicive(R)  Medical Enterprise Data System, a proprietary
software architecture developed to collect,  store, retrieve and analyze a broad
range of information used in the healthcare industry.

         Further, our web accessible solutions include portals for key
stakeholders in the care delivery process--consumers, physicians and care
managers--thus permitting real-time sharing of information and support the
adherence to our health and disease intervention programs. The key technology we
use for effective care coordination include:

                    o    Health-e-Coordinator(TM),  a web-based care  management
                         application;
                    o    MyFamilyMD(TM), a consumer health management portal;
                    o    CarePrime(R),   a   clinical   care   application   for
                         physicians and clinicians; and
                    o    I-talk(TM), interactive smart voice technology.

                  Interventions and Clinical Expertise

         Our personalized  health and disease  interventions  include  intensive
programs for  individuals  who suffer from,  or are at high risk for,  active or
chronic  disease and  tailored  programs  for  individuals  who are at low risk.
Depending on the individual's  level of risk, our custom tailored  interventions
include self-help programs available through the web or person-assisted programs
administered through our Care Communication  Center, which is staffed by skilled
nurses and other  health  professionals  24 hours per day, 7 days per week.  All
interventions   include  lifestyle  and  risk  reduction  programs  that  follow
evidence-based clinical guidelines to optimize health, fitness, productivity and
quality of life.



                                      -4-


         We have  designed and are  implementing  interventions  for a number of
specific chronic conditions,  including congestive heart failure (CHF), coronary
artery disease (CAD), asthma, diabetes, cancer management, cystic fibrosis lower
back pain and chronic obstructive pulmonary disease (COPD).

                  Care Communication Center

         Our Care Communications Center is staffed with skilled nurses and other
healthcare  professionals 24 hours per day, 7 days per week. Through the Center,
we effect  targeted  interventions  to  improve  the  health  management  of the
populations we serve.  The Center helps consumers make informed  decisions about
their health and provides ongoing support for those with chronic  diseases.  Our
demand management and nurse triage services incorporate  nationally  recognized,
evidence-based  clinical  guidelines to ensure that all caregivers and consumers
are following the best practices.

         Everything we do is built on information,  which drives decision-making
and results. Information guides the identification of consumers, the utilization
of  protocols   that  provide  high  quality  and  cost   effective   care,  the
communication  among the key  stakeholders  and ultimately the return on capital
invested in providing healthcare.  When all of these components are in place, we
believe  that  consumer  satisfaction  will  increase and the costs of providing
quality healthcare will decrease.

         I-trax, Inc.--Holding Company

         I-trax was  incorporated in the State of Delaware on September 15, 2000
at the  direction  of  the  board  of  directors  of  I-trax  Health  Management
Solutions,  Inc.  (or Health  Management),  I-trax's  then  parent  company.  On
February 5, 2001,  I-trax became the holding company of Health Management at the
closing of a  reorganization  pursuant  to Section  251(g) of  Delaware  General
Corporation  Law. The holding  company  reorganization  was described in greater
detail in  I-trax's  registration  statement  on Form S-4  (Registration  Number
333-48862), filed with the SEC on October 27, 2000. At the effective time of the
reorganization   all  of  the  stockholders  of  Health  Management  became  the
stockholders of I-trax and Health Management became a wholly owned subsidiary of
I-trax. Further, all outstanding shares of Health Management were converted into
shares of I-trax in a non-taxable transaction. Health Management no longer files
reports  with the SEC.  However,  I-trax does file reports with the SEC, and its
common stock is traded on the American Stock Exchange under the symbol "DMX."

         The holding company structure has allowed us greater flexibility in our
operations and expansion and diversification plans, including in the acquisition
of WellComm  Group,  Inc. on February 6, 2002 and iSummit  Partners,  LLC, doing
business as "MyFamilyMD," on February 7, 2001.

         I-trax  acquired  WellComm  effective  February  6, 2002 in a  two-step
reorganization  pursuant  to a Merger  Agreement  dated  January 28, 2002 by and
among I-trax, WC Acquisition,  Inc., an Illinois  corporation and a wholly-owned
subsidiary of I-trax,  WellComm and WellComm's two principals.  The initial step
of the reorganization  transaction  involved a merger of WC Acquisition with and
into WellComm, in which merger WellComm continued as the surviving  corporation.
The second step of the reorganization transaction involved a statutory merger of
WellComm with and into I-trax, in which merger I-trax continued as the surviving
corporation.



                                      -5-


         At the closing of the  WellComm  merger,  we  delivered to the WellComm
stockholders approximately $2,200,000 in cash and 1,488,000 shares of our common
stock,  and to each of two senior officers of WellComm options to acquire 56,000
shares of our common stock at a nominal exercise price. After the merger,  three
executive officers of WellComm joined us as senior executives and WellComm's two
principal stockholders were elected to our board of directors.

         We funded the  acquisition  of  WellComm  by  selling a 6%  convertible
senior  debenture in the  aggregate  principal  amount of $2,000,000 to Palladin
Opportunity  Fund LLC pursuant to a Purchase  Agreement  dated as of February 4,
2002 between Palladin and us. Pursuant to the purchase agreement, we also issued
Palladin a warrant to purchase  up to 307,692  shares of our common  stock.  The
outstanding  principal and any interest  under the debenture are payable in full
on or before February 3, 2004. Further,  outstanding  principal and any interest
may be converted at any time at the election of Palladin  into our common stock.
The  conversion  price under the  debenture,  and the  exercise  price under the
warrant,  is $1.75.  The  current  conversion  price is subject to "reset" as of
August 4, 2003 but only if the  closing  bid price  for  I-trax's  common  stock
averaged  during a period of 20  consecutive  trading  days  ending on August 3,
2003, is less than the then current conversion price.

         I-trax  acquired  iSummit  effective  February  7, 2001 in an  exchange
transaction  pursuant to a Contribution  and Exchange  Agreement dated September
22, 2000,  as amended,  by and among  iSummit,  I-trax,  Health  Management  and
iSummit's three members. I-trax issued 580,682 shares of common stock to acquire
iSummit (reflecting a post closing adjustments to the aggregate number of issued
shares effective as of December 31, 2001).

         I-trax Health Management Solutions, Inc.--Operating Subsidiary

         Health  Management  is a  predecessor  to I-trax  and is our  operating
subsidiary.  It was  incorporated  in the  State of  Delaware  under the name of
Marmac  Corporation  in May 1969. In December  1979, it changed its name to Ibex
Industries International, Inc. On April 1, 1996, Health Management purchased the
assets  of  certain  physician  practices,  changed  its  name to  U.S.  Medical
Alliance,  Inc.,  and commenced  operations as a physician  practice  management
company.

         As U.S. Medical Alliance,  Health  Management  completed one additional
physician practice  acquisition.  However, it did not have adequate liquidity or
capital resources to withstand the downturn in the physician practice management
industry, nor the ability to acquire profitable physician practices.  In January
1997, the board of directors of Health  Management,  in an effort to reorganize,
elected Frank A. Martin as its  President.  Mr. Martin  negotiated the return of
the previously  acquired physician practice assets to the physicians in exchange
for the cancellation of any Health Management  capital stock or notes associated
with those acquisitions.  Health Management changed its name to I-Trax.com, Inc.
in August 1999.

         Health Management merged with Member-Link  effective  December 30, 1999
pursuant to a Merger  Agreement  dated as of December 14,  1999.  In the merger,
Health  Management  issued an aggregate of 1,554,368 shares (as adjusted) of its
common stock. On February 7, 2001,  Health  Management and I-trax  completed the
previously described holding company  reorganization.  Health Management assumed
its current name, I-trax Health Management Solutions, Inc., on March 21, 2001.

                                  RISK FACTORS

         In addition to other information  contain and incorporated by reference
in this prospectus,  you should  carefully  consider the following risks and the
other information in evaluating I-trax and its business. Our business, financial
condition and results of operations  could be materially and adversely  affected
by each of these risks.  Such an adverse  effect could cause the market price of
our common stock to decline, and you could lose all or part of your investment.

Risk Related to I-trax

         We  have  a  history  of  operating  losses  and  anticipate  continued
         operating losses through the third quarter of 2003.

         We have used substantial cash to fund our operating losses, and we have
never earned a profit.  Through March 31, 2003, we have used approximately $13.4
million of cash to fund our  operating  activities.  Moreover,  we expect to use
additional cash to fund our operating  losses through the third quarter of 2003.
Our ability to achieve profitability will depend, in part, on:

          o    the commercial success of our service and software applications;

          o    successful  deployment and retention of our services and software
               applications by our customers; and

          o    our sales and marketing activities.

         The success of our business model depends on attracting customers, such
as public health agencies,  hospitals, health plans, self-insured employers, and
colleges  and  universities,  to our  population  health  management  solutions.
Although  we believe  that this  business  model will be  successful,  we cannot
assure you that we will achieve or sustain  profitability  or that our operating
losses will not increase in the future.

         We will require  additional  capital to fund our  operating  losses and
         improve our products and services.

         Additional   funds  are  required  to  complete  our  planned   product
development  efforts,  expand our sales and marketing  activities,  and to cover
cash  shortfalls  until our  current and  projected  pipeline  materializes.  At
present,  we  expect  to  obtain  such  funds  from  operations  and  financings
activities.   Financing  activities  may  include  equity  or  debt  financings,
strategic  alliances  with  corporate  partners  and  others,  or through  other
sources.  We cannot provide assurance that additional  funding will be available
on acceptable terms, if at all. If adequate funds are not available, we may have
to delay,  scale-back or eliminate  certain aspects of our operations or attempt
to obtain funds  through  arrangements  with  collaborative  partners or others.
Moreover,  if we  continue  to have  operating  losses  and are unable to obtain
capital to cover them, we may be unable to remain in business. These results, in
turn,  could  cause  the   relinquishment  of  our  rights  to  certain  of  our
technologies,  products or potential markets,  dilution of your ownership in our
business,  or our loss of what we believe is a current competitive  advantage in
technology enabled population health management field. Therefore,  the inability
to obtain  adequate funds could have a material  adverse impact on our business,
financial condition and results of operations.

         The  segment  of  the  healthcare  industry  in  which  we  operate  is
         relatively new and our sales cycle is long and complex.

         The disease and population health management business, although growing
rapidly,  is a relatively new segment of the overall healthcare industry and has
many entrants.  Many companies use the generic label of "disease  management" to
characterize  activities  ranging from the sale of medical supplies and drugs to
services aimed at managing demand for healthcare services.  Because this segment
of the industry is  relatively  new,  potential  purchasers  take a long time to
evaluate and purchase such services,  lengthening our sales cycle.  Further, the
sales and implementation  process for our services and software  applications is
lengthy,  involves a significant technical evaluation and requires our customers
to commit a great deal of time and money.  Finally,  the sale and implementation
of our solutions are subject to delays due to our  customers'  internal  budgets
and  procedures  for


                                      -7-


approving  large  capital  expenditures  and deploying new services and software
applications  within  their  organizations.  The sales cycle for our  solutions,
therefore,  is  unpredictable  and has generally ranged from 3 to 24 months from
initial  contact  to  contract  signing.  The  time it takes  to  implement  our
solutions is also  difficult to predict and has lasted as long as 18 months from
contract execution to the commencement of live operation. During the sales cycle
and the implementation  period, we may expend substantial time, effort and money
preparing  contract  proposals,  negotiating the contract and  implementing  the
solution without receiving any related revenue.

         Our limited  operating  experience may cause us to misjudge the segment
         of the healthcare industry in which we are operating.

         We have  only  recently  begun  to  design,  build  and  offer  disease
management  and  comprehensive  health  management  solutions.   Our  enterprise
software  applications  have been  operational  for less than  four  years,  our
web-based  solutions  have  been  operational  for less  than two  years and our
disease  management  and  comprehensive  health  management  solutions have been
operational for only one year. Accordingly,  we have a limited operating history
in our  business.  Furthermore,  we are also facing other risks and  challenges,
including  a lack of  meaningful  historical  financial  data upon which to plan
future  budgets,   increasing   competition,   the  need  to  develop  strategic
relationships, and other risks described below. We cannot guarantee that we will
be able  successfully to implement our business model. An investor in our common
stock  must  consider  the  risks,  uncertainties,   expenses  and  difficulties
frequently  encountered by companies in their early stages of development.  As a
result of the absence of meaningful  history and experience in our business,  we
may easily misjudge the nature or size of our perceived  markets,  or the amount
of work or capital  necessary to complete  our pending  products or to implement
our business plan.

         We may be unable to  implement  our  business  strategy  to deploy  our
         products effectively and attract customers.

         Although we believe that there is  significant  demand for our services
and products in the overall healthcare market, there are many reasons why we may
be unable to execute our business strategy, including our possible inability to:

          o    deploy our services and software applications on a large scale;

          o    attract a  sufficiently  large number of public health  agencies,
               hospitals,  health plans, self-insured employers and colleges and
               universities   to   subscribe   for  our  services  and  software
               applications;

          o    increase awareness of our brand;

          o    strengthen user loyalty;

          o    develop and improve our services and software applications;

          o    continue  to  develop  and  upgrade  our  services  and  software
               applications; and

          o    attract, retain and motivate qualified personnel.

         The healthcare industry is subject to cost pressures.

         The healthcare industry is currently under pressure by governmental and
private-sector  revenue  sources to cut spiraling  costs.  These  pressures will
continue  and  possibly  intensify.  Although we believe  that our  services and
software applications assist public health agencies, hospitals, health plans and
self-insured  employers to control the high costs  associated with the treatment
of chronic  diseases,  the pressures to reduce costs  immediately may hinder our
ability (or the length of time we require) to obtain new contracts. In addition,
the focus on cost reduction may pressure our customers to restructure  contracts
and reduce our fees.




                                      -8-




         Government regulation could adversely affect our business.

         Many of our existing and potential  clients are subject to considerable
state and federal government regulations.  Many of these regulations are vaguely
written and subject to  differing  interpretations  that may, in certain  cases,
result in  unintended  consequences  that may affect our ability to  effectively
deliver our services.  Regulatory and legislative efforts currently focus on the
confidentiality of patient  identifiable  medical  information,  as evidenced by
such legislation as the Health Insurance  Portability and  Accountability Act of
1996  (or  HIPAA).   While  we  believe  that  our  ability  to  obtain  patient
identifiable medical information for disease management purposes from certain of
our clients is  protected in recently  released  federal  regulations  governing
medical record  confidentiality,  state  legislation or regulations will preempt
federal legislation if it is more restrictive. Accordingly, new federal or state
legislation or regulations  restricting the  availability of this information to
us or leaving  uncertain  whether  disease  management  is an  allowable  use of
patient  identifiable  medical information would have a material negative effect
on us.

         Although  we are  not  directly  subject  to  many  of the  regulations
governing  healthcare  delivery,  our clients,  such as public health  agencies,
hospitals,   health  plans,  and  self-insured   employers,   must  comply  with
regulations  including the licensing and reimbursement  requirements of federal,
state  and local  agencies.  Further,  certain  of our  professional  healthcare
employees,  such as doctors and  nurses,  are  subject to  individual  licensing
requirements.  All of our healthcare  professionals who are subject to licensing
requirements  are  licensed in the state in which they are  physically  present.
Multiple state licensing  requirements for healthcare  professionals who provide
services  telephonically  over state lines may require us to license some of our
healthcare  professionals  in more than one state.  We  continually  monitor the
developments in telemedicine.  There is no assurance, however, that new judicial
decisions or federal or state  legislation or regulations would not increase the
requirement for multi-state  licensing of all central operating unit call center
health  professionals,  which would  significantly  increase our  administrative
costs.

         We are  indirectly  affected  by changes in the laws  governing  health
plan,  hospital  and  public  health  agency  reimbursement  under  governmental
programs  such as Medicare  and  Medicaid.  There are periodic  legislative  and
regulatory  initiatives  to reduce the  funding  of the  Medicare  and  Medicaid
programs in an effort to curtail or reduce overall federal healthcare  spending.
Federal  legislation has and may continue to  significantly  reduce Medicare and
Medicaid  reimbursements  to most  hospitals.  These  reimbursement  changes are
negatively affecting hospital revenues and operations. There can be no assurance
that such legislative  initiatives or government regulations would not adversely
affect our operations or reduce demand for our services.

         Various  federal  and  state  laws  regulate  the  relationship   among
providers of healthcare  services,  other healthcare  businesses and physicians.
The "fraud and abuse"  provisions  of the Social  Security Act provide civil and
criminal  penalties  and  potential  exclusion  from the  Medicare  and Medicaid
programs  for  persons  or  businesses  who  offer,   pay,  solicit  or  receive
remuneration  in order to  induce  referrals  of  patients  covered  by  federal
healthcare  programs  (which  include  Medicare,  Medicaid,  TriCare  and  other
federally  funded  health  programs).  Although  we  believe  that our  business
arrangements with our clients are in compliance with these statutes, these fraud
and  abuse  provisions  are  broadly  written  and  the  full  extent  of  their
application is not yet known. We are therefore unable to predict the effect,  if
any, of broad enforcement interpretation of these fraud and abuse provisions.

         Our  dependence  on  the  Internet  and  Internet-related  technologies
         subjects us to frequent change and risks.

         Our  web-based  software  applications  that form the  backbone  of our
disease management and comprehensive  health management  solutions depend on the
continuous,  reliable  and secure  operation  of  Internet  servers  and related
hardware and software.  In the past,  several large Internet commerce  companies
have suffered highly  publicized  system  failures,  which depressed their stock
prices,  caused significant  negative publicity and sometimes led to litigation.
It is possible that we may also suffer service outages from time to time. To the
extent that our service is interrupted, our users will be inconvenienced and our
reputation may be diminished.  If access to our system becomes  unavailable at a
critical time,  users could allege we are liable,  which could depress our stock
price,  cause  significant  negative  publicity and possibly lead to litigation.
Although our computer and  communications  hardware is protected by physical and
software  safeguards,  it is still vulnerable to fire, storm, flood, power loss,
telecommunications  failures, physical or software break-ins and similar events.
We will not have 100%



                                      -9-


redundancy  for  all  of  our  computer  and  telecommunications  facilities.  A
catastrophic  event could have a  significant  negative  effect on our business,
results of operations, and financial condition.

         We also depend on third parties to provide  certain of our clients with
Internet and online services necessary for access to our servers. It is possible
that our clients will  experience  difficulties  with  Internet and other online
services due to system failures,  including  failures  unrelated to our systems.
Any sustained disruption in Internet access provided by third parties could have
a material  adverse effect on our business,  results of operations and financial
condition.

         Finally, we retain confidential  healthcare information on our servers.
It is, therefore,  critical that our facilities and infrastructure remain secure
and are  perceived  by clients to be secure.  Although we operate  our  software
applications  from a secure  facility  managed by a reputable  third party,  our
infrastructure  may be  vulnerable  to  physical  break-ins,  computer  viruses,
programming  errors or similar disruptive  problems.  A material security breach
could damage our reputation or result in liability to us.

         We may be sued by our users if we provide inaccurate health information
         on  our  website  or   inadvertently   disclose   confidential   health
         information to unauthorized users.

         Because  users of our website will access  health  content and services
relating to a medical  condition  they may have or may distribute our content to
others,  third  parties  may sue us for  defamation,  negligence,  copyright  or
trademark  infringement,  personal injury or other matters. We could also become
liable if confidential information is disclosed inappropriately.  These types of
claims have been brought, sometimes successfully, against online services in the
past.  Others  could  also sue us for the  content  and  services  that  will be
accessible  from our website  through links to other websites or through content
and materials that may be posted by our users in chat rooms or bulletin  boards.
Any such liability will have a material adverse effect on our reputation and our
business, results of operations or financial position.

         Our business  will be  adversely  affected if we lose a key employee or
         fail to recruit and retain other skilled employee.

         Our  Chairman  and Chief  Executive  Officer,  Frank A.  Martin,  is an
integral part of our business and our future  success  greatly  depends upon his
retention.  Our  failure to retain Mr.  Martin  could  significantly  reduce our
ability to compete and succeed in the future.

         Our future  success also depends on our ability to attract,  retain and
motivate highly skilled employees.  As we secure new contracts and implement our
services  and  products,  we  will  need  to hire  additional  personnel  in all
operational areas. We may be unable to attract, assimilate or retain such highly
qualified  personnel.  We  have  in  the  past  experienced,  and we  expect  to
experience  in the future,  difficulty in hiring and  retaining  highly  skilled
employees with  appropriate  qualifications.  If we do not succeed in attracting
new personnel or retaining and  motivating our current  personnel,  our business
will be adversely affected.

         We may be unable to compete  successfully  against  companies  offering
         similar products.

         Many healthcare  companies are offering disease management services and
healthcare focused software solutions.  Further, a vast number of Internet sites
offer  healthcare  content,  products and  services.  In  addition,  traditional
healthcare  providers compete for consumers'  attention both through traditional
means as well as through  new  Internet  initiatives.  Although  we believe  our
technology-enabled   service   solutions   are  unique   and  better   than  our
competitors', we compete for customers with numerous other businesses.

         Many of these  potential  competitors  are likely to enjoy  substantial
competitive advantages compared to us, including:

          o    greater  name  recognition  and  larger  marketing   budgets  and
               resources;

          o    larger customer and user bases;



                                      -10-


          o    larger production and technical staffs;

          o    substantially  greater financial,  technical and other resources;
               and

          o    a wider array of online products and services.

         To be  competitive,  we must  continue  to  enhance  our  products  and
services,  as  well as our  sales  and  marketing  channels  and  our  financial
condition.

         We may be exposed to liability claims.

         We maintain professional malpractice,  errors and omissions and general
liability insurance for all of our locations and operations. Although we believe
that these  insurance  policies  are  adequate  in amount and  coverage  for our
current  operations,  there can be no assurance  that  coverage is sufficient to
cover all future claims or will continue to be available in adequate  amounts or
at a reasonable cost.

         I-trax Health Management Solutions, Inc., our operating subsidiary, had
engaged in the physician practice  management  business.  While we are no longer
engaged  in  that  business,   Health  Management  may  be  subject  to  unknown
liabilities  arising  from  such  prior  business  operations,  which may have a
material adverse effect on our business,  operations,  financial  condition,  or
prospects.

         Member-Link  Systems,  Inc.,  a company we acquired in 1999 by way of a
merger with Health Management, was engaged in the business of marketing, selling
and installing eImmune(R) and AsthmaWatch(R)  applications.  Since beginning its
operations in 1996 until March 15, 2000,  Member-Link and Health  Management did
so without obtaining product or professional  liability insurance.  Accordingly,
if any customer of Member-Link or Health  Management  should in the future claim
that the software  applications  Member-Link and Health Management sold prior to
obtaining  insurance  on March 15,  2000 were  defective,  we would not have the
protection of insurance in satisfying or defending  against such claims. At this
time we are not aware of any such claims. Any such claims, however, could have a
material  adverse  effect on our  business,  results  of  operations,  financial
condition and prospects.

         Our clients may sue us if any of our software  applications or services
is  defective,  fails to perform  properly or injures  the user.  Even though we
currently have insurance,  claims could require us to spend significant time and
money  in  litigation,  to pay  significant  damages  and to  reserve  for  such
liability on our financial statements. At this time we are not aware of any such
claims.  However,  any such claims,  whether or not successful,  could seriously
damage our  reputation  and our  business,  results of  operations  or financial
position.

         If our  intellectual  property  rights are undermined by third parties,
         our business will suffer.

         Our  intellectual  property is important to our business.  We rely on a
combination  of  copyright,  trademark  and trade secret  laws,  confidentiality
procedures and contractual  provisions to protect our intellectual property. Our
efforts  to  protect  our  intellectual  property  may  not  be  adequate.   Our
competitors  may  independently  develop  similar  technology  or duplicate  our
products or services.  Unauthorized  parties may infringe upon or misappropriate
our products, services or proprietary information. In addition, the laws of some
foreign countries do not protect  proprietary  rights as well as the laws of the
United  States do, and the global  nature of the Internet  makes it difficult to
control the ultimate  destination  of our products and services.  In the future,
litigation may be necessary to enforce our  intellectual  property  rights or to
determine the validity and scope of the proprietary  rights of others.  Any such
litigation would probably be  time-consuming  and costly. We could be subject to
intellectual property infringement claims as the number of our competitors grows
and the content and functionality of software  applications and services overlap
with  competitive  offerings.  Defending  against  these  claims,  even  if  not
meritorious,  could be expensive  and divert our  attention  from  operating our
company.  If we become liable to third parties for infringing their intellectual
property  rights,  we could be required to pay a  substantial  damage  award and
forced to develop  noninfringing  technology,  obtain a license or cease selling
the  applications  that contain the infringing  technology.  We may be unable to
develop noninfringing  technology or obtain a license on commercially reasonable
terms,  or at all. We also intend to rely on a variety of  technologies  that we
will  license from third  parties,  including  any database and Internet  server
software,  which will be used to operate  our  applications.  These  third-party
licenses


                                      -11-


may not be  available to us on  commercially  reasonable  terms.  The loss of or
inability  to  obtain  and  maintain  any of  these  licenses  could  delay  the
introduction of enhancements to our software applications, interactive tools and
other features until equivalent  technology could be licensed or developed.  Any
such  delays  could  materially  adversely  affect  our  business,   results  of
operations and financial condition.

         Provisions of our certificate of incorporation  could impede a takeover
         of our company even though a takeover may benefit our stockholders.

         Our board of directors has the authority, without further action by the
stockholders,  to issue from time to time,  up to 2,000,000  shares of preferred
stock in one or more classes or series, and to fix the rights and preferences of
such  preferred  stock.  We are subject to provisions of Delaware  corporate law
which,  subject to certain  exceptions,  will  prohibit us from  engaging in any
"business   combination"  with  a  person  who,  together  with  affiliates  and
associates,  owns 15% or more of our common stock  (referred to as an interested
stockholder)  for a period of three  years  following  the date that such person
became an interested stockholder, unless the business combination is approved in
a  prescribed  manner.  Additionally,  our bylaws  establish  an advance  notice
procedure for stockholder  proposals and for nominating  candidates for election
as  directors.  These  provisions  of  Delaware  law and of our  certificate  of
incorporation  and  bylaws  may  have  the  effect  of  delaying,  deterring  or
preventing a change in our control,  may discourage bids for our common stock at
a premium over market price and may adversely  affect the market price,  and the
voting and other rights of the holders of our common stock.

         Our officers and directors  have  effective  control of the company and
         other stockholders may have little or no voice in corporate management.

         Our  Chairman,  the  venture  capital  firm with which our  Chairman is
affiliated,  three  other  members  of our  management  team  and two  directors
beneficially own, in the aggregate,  approximately 30% of the outstanding shares
of  our  common  stock.  As  a  result,  these  stockholders,  acting  together,
effectively  control the election of directors and matters requiring approval by
our stockholders.  Thus, they may be able to prevent corporate transactions such
as future  mergers that might be favorable from our standpoint or the standpoint
of the other stockholders.

         The loss of any of our very  limited  number of  customers  will have a
         material adverse effect on our business.

         Historically,  a very limited  number of customers  has accounted for a
significant  percentage of our revenues.  In 2001, our largest customer,  Walter
Reed Army  Medical  Center,  accounted  for 84% of our  revenues.  In 2002,  our
largest customers, UICI and Aetna Health Management,  Inc. accounted for 42% and
30% of our revenues,  respectively. We anticipate that our results of operations
in any given period will continue to depend to a significant extent upon a small
number of  customers.  Accordingly,  if we were to lose the  business  of even a
single  customer,  our results of operations  would be materially  and adversely
affected.

         If we cannot repay the  debenture  we sold to  Palladin,  we will be in
         default  on a  material  obligation,  which  will  cause us to suffer a
         material adverse event.

         We owe Palladin $2,000,000 under a 6% convertible senior debenture.  If
Palladin  does not convert this sum into our common  stock,  this sum,  together
with interest,  must be repaid on February 3, 2004. If we do not have sufficient
funds to repay  this sum on  debenture's  due date,  we will be in  default on a
material  obligation  and as a  result  our  operations  may be  materially  and
adversely effected.

Investment Risks

         The price of our common stock is volatile.

         Our stock price has been and we believe  will  continue to be volatile.
For example,  in 2002,  the per share price of our stock has  fluctuated  from a
high of $7.65 to a low of $2.50. The stock's volatility may be influenced by the
market's  perceptions of the healthcare  sector in general,  or other  companies
believed to be similar to us or by the market's perception of our operations and
future prospects. Many of these perceptions are beyond our control. In


                                      -12-


addition,  our stock is not heavily  traded and therefore the ability to achieve
relatively  quick  liquidity  without a  negative  impact on our stock  price is
limited.

         Shares  eligible for future sale upon the  conversion  of the debenture
         and  upon the  exercise  of  issued  options  and  warrants  may  cause
         significant dilution.

         Palladin  Opportunity  Fund, LLC purchased from us a debenture with the
principal  amount of  $2,000,000.  The  debenture  and  accrued  interest on the
debenture  is  convertible  into such  number of shares of our  common  stock as
determined by dividing the principal  amount and accrued interest thereon by the
then current  conversion  price.  If converted on June 30, 2003,  the  debenture
would  convert into  approximately  1,240,960  shares of our common  stock.  Our
stockholders,  therefore,  could  experience  dilution of their  investment upon
conversion  of the  debenture.  The  shares of common  stock  issuable  upon the
conversion of the debenture are registered  under the Securities Act of 1933, as
amended (or  Securities  Act),  and may be sold by Palladin,  subject to certain
limitations, at any time.

         As of June 30, 2003, approximately 5,444,092 shares of our common stock
were reserved for issuance upon exercise of our outstanding warrants and options
in addition to the shares of our common stock reserved for issuance upon the
conversion of the debenture.

         We may need  additional  funds in the future which may not be available
         and which may result in dilution of the value of our common stock

         In the future, we may need to raise additional funds,  which may not be
available on favorable  terms, if at all. If adequate funds are not available on
acceptable  terms,  we may be  unable  to fund our  business  growth  plans.  In
addition,  if funds are available,  the issuance of securities  could dilute the
value of shares of our common stock and cause the market price to fall.

          (1)  The  number  of shares  set  forth in the  table for the  selling
               shareholders  represents  a good faith  estimate of the number of
               shares of common stock to be offered by the selling shareholders.
               The  actual  number  of  shares of  common  stock  issuable  upon
               conversion of the debenture and exercise of the related  warrants
               is subject to  adjustment  and could be  materially  less or more
               than such estimated  number depending on factors which cannot now
               be  predicted  by  us  including,  among  other  factors,  future
               anti-dilution  adjustments  under the debenture and the warrants.
               The  actual  number of shares of  common  stock  offered  in this
               prospectus,  and included in the registration  statement of which
               this  prospectus is a part,  includes such  additional  number of
               shares  of  common  stock  as  may be  issued  or  issuable  upon
               conversion of the debenture and exercise of the related  warrants
               by  reason  of  any  stock  split,   stock  dividend  or  similar
               transaction  involving the common stock,  in accordance with Rule
               416 under the Securities Act.

          (2)  Under the terms of the  debenture,  if the debenture and interest
               accrued on the debenture had actually been  converted on June 30,
               2003, the  conversion  price would have been $1.75 and the shares
               of our common  stock  issuable  upon  conversion  would have been
               1,240,960.  Under  the  terms  of the  Palladin  warrant,  if the
               warrant had actually been  exercised on June 30, 2003, the shares
               of our common stock  issuable  upon the exercise  would have been
               307,692 and the  exercise  price would have been $1.75.  Palladin
               may not  convert its  debentures  or exercise  its  warrants  for
               shares  of common  stock in  excess  of that  number of shares of
               common  stock that,  upon  giving  effect to such  conversion  or
               exercise,  would cause the  aggregate  number of shares of common
               stock beneficially owned by Palladin and its affiliates to exceed
               9.99% of the  outstanding  shares of the common  stock  following
               such  conversion  or  exercise;   therefore,  Palladin  disclaims
               beneficial  ownership  of any shares of common stock in excess of
               such amount.

          (3)  Under the terms of the JG Capital  warrant,  if the  warrant  had
               actually  been  exercised  on June 30, 2003,  the exercise  price
               would have been $1.75 and the shares of our common stock issuable
               upon the exercise would have been 114,285.

                              PLAN OF DISTRIBUTION

         The  shares  being  offered  by  the  selling   shareholders  or  their
respective pledgees,  donees,  transferees or other successors in interest, will
be sold from time to time in one or more  transactions,  which may involve block
transactions:

          o    on the American  Stock  Exchange or on such other market on which
               the common stock may from time to time be trading;

          o    in privately-negotiated transactions;

          o    through the writing of options on the shares;

          o    short sales; or

          o    any combination thereof.

          The  sale price to the public may be:

          o    the market price prevailing at the time of sale;

          o    a price related to such prevailing market price;

          o    at negotiated prices; or

          o    such other price as the selling shareholders  determine from time
               to time.

         The  shares  may  also  be  sold  pursuant  to Rule  144.  The  selling
shareholders  shall  have the sole and  absolute  discretion  not to accept  any
purchase  offer or make any sale of shares if they deem the purchase price to be
unsatisfactory at any particular time.

         The  selling  shareholders  or  their  respective   pledgees,   donees,
transferees or other  successors in interest,  may also sell the shares directly
to market makers acting as  principals  or  broker-dealers  acting as agents for
themselves or their  customers.  These  broker-dealers  may be compensated  with
discounts,  concessions  or  commissions  from the selling  shareholders  or the
purchasers of shares for whom such  broker-dealers  may act as agents or to whom
they  sell  as  principal  or  both.  The   compensation   as  to  a  particular
broker-dealer  might be greater than  customary  commissions.  Market makers and
block  purchasers  purchasing the shares will do so for their own account and at
their own risk.  The selling  shareholders  may sell  shares of common  stock in
block  transactions  to market makers or other  purchasers at a price per share,
which may be below the then market price. The selling shareholders cannot assure
that all or any of the shares offered in this  prospectus  will be issued to, or
sold by, the selling  shareholders.  The selling  shareholders  and any brokers,
dealers or agents,  upon effecting the sale of any of the shares offered in this
prospectus,  may be  deemed  "underwriters"  as that term is  defined  under the
Securities Act or the  Securities  Exchange Act of 1934 (or Exchange Act) or the
rules and regulations under such acts.

         The selling  shareholders,  alternatively,  may sell all or any part of
the  shares  offered  in this  prospectus  through  an  underwriter.  No selling
stockholder  has entered into any agreement with a prospective  underwriter  and
there is no assurance that any such agreement will be entered into. If a selling
shareholders  enters into such an agreement or agreements,  the relevant details
will be set forth in a supplement or revisions to this prospectus.

         The selling  shareholders  and any other persons  participating  in the
sale of the shares may be subject to  applicable  provisions of the Exchange Act
and the rules  and  regulations  under  the  Exchange  Act,  including,  without
limitation,  Regulation M. These provisions may restrict certain  activities of,
and limit the timing of purchases  and sales of shares of the  Company's  common
stock by, the selling shareholders or any other such person.

ITEM 15. INDEMNIFICATION OF OFFICERS AND DIRECTORS

         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 he 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,
judgments, fines and amounts paid in settlement actually and reasonably incurred
by him in  connection  with such action,  suit or proceeding if he acted in good
faith and in a manner he 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 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  actually and reasonably  incurred by him in connection
with the defense or  settlement of such action or suit if he acted in good faith
and in a manner  he  reasonably  believed  to be in or not  opposed  to the best
interests  of the  corporation,  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
such adjudication of liability, such person is fairly and reasonably entitled to
be indemnified for such expenses which the court shall deem proper.

         Section 145 of the Delaware  General  Corporation Law further  provides
that to the extent a director  or  officer  of a Delaware  corporation  has been
successful  in the  defense of any  action,  suit or  proceeding  referred to in
subsections  (a) or (b) of Section 145 or in the defense of any claim,  issue or
matter  therein,  he shall be  indemnified  against any  expenses  actually  and
reasonably  incurred by him in connection  therewith;  that the  indemnification
provided for by Section 145 shall not be deemed exclusive of any rights to which
the  indemnified  party may be entitled  and the  corporation  may  purchase and
maintain insurance on behalf of a director or officer of the corporation against
any  liability  asserted  against him or incurred by him in any such capacity or
arising out of his status as such whether or not the corporation  would have the
power to indemnify him against such liabilities under Section 145.

         Section  102(b)(7) of the Delaware  General  Corporation  Law permits a
Delaware corporation to include a provision in its Certificate of Incorporation,
and I-trax's  Certificate  of  Incorporation  contains such a provision,  to the



                                     -II-1-


effect that, subject to certain exceptions, a director of a Delaware corporation
is not personally  liable to the  corporation or its  stockholders  for monetary
damages for a breach of his fiduciary duty as a director.

         I-trax's By-laws also provide that I-trax shall indemnify its directors
and officers and, to the extent  permitted by the Board of  Directors,  I-trax's
employees  and  agents,  to the  full  extent  permitted  by  and in the  manner
permissible  under  the laws of the State of  Delaware.  In  addition,  I-trax's
By-laws  permit the Board of Directors to authorize  the Company to purchase and
maintain  insurance against any liability  asserted against any of the Company's
directors, officers, employees or agents arising out of their capacity as such.

ITEM 17.          UNDERTAKINGS

         The undersigned registrant hereby undertakes to:

         (1) File, during any period in which it offers or sells  securities,  a
post-effective   amendment  to  this  registration   statement  to  include  any
additional or changed material information on the plan of distribution.

         (2) For  determining  liability  under the  Securities  Act, treat each
post-effective  amendment  as a new  registration  statement  of the  securities
offered,  and the offering of the securities at that time to be the initial bona
fide offering.

         (3) File a post-effective  amendment to remove from registration any of
the securities that remain unsold at the end of the offering.




                                     -II-2-


         Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors,  officers and controlling  persons of
the small business  issuer pursuant to the foregoing  provisions,  or otherwise,
the small business issuer has been advised that in the opinion of the Securities
and  Exchange  Commission  such  indemnification  is  against  public  policy as
expressed in the Act and is, therefore, unenforceable. In the event that a claim
for  indemnification  against  such  liabilities  (other than the payment by the
small  business  issuer of expenses  incurred or paid by a director,  officer or
controlling person of the small business issuer 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 small business
issuer 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.




                                     -II-3-

to the registration statement on Form SB-2 and has duly caused this registration
statement  to be  singed  on its  behalf  by  the  undersigned,  thereunto  duly
