Dear Stockholders:

I am pleased to enclose the proxy statement for our Special Meeting of stockholders to be held on July 29, 2011. We are asking stockholders to approve the sale of our molded rubber products business, operated by our Green Tech Products, Inc. subsidiary, to Irish Knight Holdings, L.L.C. for consideration consisting of (i) the assumption of substantially all of Green Tech Products’ liabilities (which were approximately $1,100,000 at March 31, 2011, including all of Green Tech Products’ loans from Great Western Bank, which will be repaid to such bank directly by Irish Knight Holdings), but excluding potential liabilities associated with certain pending litigation; (ii) a $50,000 stock inventory credit toward the purchase of products and services; and (iii) a promissory note in the principal amount of $100,000 (the “Transaction”).

Based on Green Tech Products’ historical performance, our Board of Directors determined it to be in the best interests of shareholder value to exit the molded rubber product business and to devote all of our corporate resources to advancing American Power Group’s dual fuel conversion business. On March 8, 2011, our Board adopted a plan to commence an immediate effort to identify potential buyers for Green Tech Products’ business and/or evaluate other strategic alternatives.

In addition, our Board of Directors has recommended to the stockholders that we amend our Restated Certificate of Incorporation to increase the number of authorized shares of common stock from 60,000,000 to 100,000,000 shares. The Board of Directors believes that the authorized common stock should be increased to provide sufficient shares for such corporate purposes as may be determined by the Board of Directors. These purposes may include, among others, the issuance of common stock to facilitate potential mergers or acquisitions, raising capital or acquiring technology rights through the sale of stock, and/or attracting or retaining valuable employees by the issuance of stock options. Except as described above or elsewhere in this proxy statement, we have no plans, understandings, commitments, agreements or undertakings concerning the issuance of any such additional shares. The Board of Directors, however, considers the authorization of additional shares of common stock advisable to ensure prompt availability of shares for issuance should the occasion arise.

The date, time, place, and agenda for the Special Meeting are set forth in the accompanying notice of Special Meeting. The accompanying proxy statement contains important information about the proposals to be submitted for a vote at the Special Meeting.

Please review this information carefully in deciding how to vote. Our Board of Directors unanimously recommends that you vote “FOR” each proposal.

YOUR VOTE ON THESE MATTERS IS IMPORTANT. Please see the accompanying notice of meeting for instructions on how to vote.

I look forward to seeing you at the meeting.

Sincerely,

Lyle Jensen

The Board of Directors is not aware of any other business to come before the Special Meeting, and unanimously recommends that you vote “FOR” these proposals.

SUMMARY

The following summary, together with the question and answer section, provides an overview of the proposals discussed in this Proxy Statement and the attached appendices. This summary also contains cross-references to the more detailed discussions elsewhere in this Proxy Statement. This summary may not contain all of the information that is important to you. To understand fully the proposed sale of our Molded Rubber Products Business and for a more complete description of the terms thereto, you should carefully read this entire Proxy Statement, including the information incorporated by reference, and the attached appendices in their entirety.

Proposal No. 1: Sale of our Molded Rubber Products Business:

General (see page 16)

Our Green Tech Products, Inc. subsidiary has entered into an Asset Purchase Agreement (the “Asset Purchase Agreement”) with Irish Knight Holdings, L.L.C. (“IKH”), pursuant to which Green Tech Products will sell to IKH substantially all the assets which constitute our molded recycled rubber products business (the “Molded Rubber Products Business”). For the fiscal year ended September 30, 2010, our Molded Rubber Products Business had revenue of $2.2 million or 87% of our total consolidated revenue and operating losses of $.86 million or 15% of our total consolidated net losses. At September 30, 2010, our Molded Rubber Products Business had total assets of $2.54 million or 37% of our total consolidated assets. For the six months ended March 31, 2011, our Molded Rubber Products Business had revenue of $0.83 million or 49% of our total consolidated revenue and operating losses of $1.06 million of 28% of our total net consolidated net losses. At March 31, 2011, our Molded Rubber Products Business had total assets of $1.25 million or 24% of our total consolidated assets.

The Parties (see page 16)

GreenMan Technologies, Inc.

We were originally founded in 1992 and have operated as a Delaware corporation since 1995. Our business is comprised of two business segments, our dual fuel conversion operations (American Power Group) and our molded recycled rubber products operations (Green Tech Products). On June 17, 2009, we signed an exclusive license agreement with American Power Group, Inc. under which we acquired the exclusive worldwide right to commercialize their patented dual fuel alternative energy technology and July 27, 2009, we purchased substantially all of their remaining operating assets, including their name but excluding the dual fuel patent. If the sale of the Molded Rubber Products Business is completed, our sole business will be to operate American Power Group’s dual fuel conversion operations.

Green Tech Products, Inc.

Green Tech Products, Inc. (formerly known as Welch Products, Inc.) is an Iowa corporation wholly owned by GreenMan since October 2007. Green Tech Products’ molded recycled rubber products operations specialize in the design, development and manufacturing of branded recycled products and services that provide schools and municipalities with environmentally responsible products to create safer work and play environments.

Irish Knight Holdings, L.L.C.

Irish Knight Holdings, L.L.C. is an Iowa limited liability company co-owned by two senior managers of Green Tech Products. IKH’s principal executive offices are located at 1701 Fernwood Lane, Algonquin, Illinois 60102, and its phone number is 847-917-3958.

Reasons for the Sale of the Molded Rubber Products Business (see page 16)

Green Tech Products has incurred operating losses aggregating approximately $5.9 million since we acquired the company on October 1, 2007. In addition, Green Tech Products has experienced declining revenues during the past two fiscal years despite ongoing investments in sales and marketing initiatives intended to promote their patented products and establish market presence. The sale of the Molded Rubber Products Business will permit us to focus all of our corporate resources on advancing our dual fuel conversion business, which we believe has much greater potential for scalability given the millions of diesel engines operated globally today. We believe the sale of the Molded Rubber Products Business and the terms of the Asset Purchase Agreement are in the best interests of our stockholders.

Our Board of Directors also considered various risks when evaluating the sale of the Molded Rubber Products Business, which include:

Effect of the Sale of the Molded Rubber Products Business (see page 17)

If our stockholders approve the sale of the Molded Rubber Products Business, we will seek to complete the sale. The sale will relieve us of material liabilities and other obligations, and will allow us to focus both management’s attention and our corporate resources to grow our dual fuel conversion business model domestically as well as world-wide and to pursue additional business opportunities that are intended to increase shareholder value.

The Asset Purchase Agreement (see page 17)

Purchase Price

As consideration for the sale of substantially all the assets of the Molded Rubber Products Business, the purchase price will be (i) the assumption of substantially all Green Tech Products’ liabilities (which were approximately $1,100,000 at March 31, 2011, including all of Green Tech Products’ loans from Great Western Bank, in an amount not to exceed $221,427 (inclusive of all principal, accrued but unpaid interest and other charges, fees and obligations), which will be repaid to such bank directly by IKH), but excluding potential liabilities associated with certain pending litigation; (ii) a $50,000 stock inventory credit toward the purchase of products and services from IKH, which credit may be applied during the first nine months after completion of the sale; and (iii) a promissory note in the principal amount of $100,000, which note would bear interest at the rate of 6% per annum and would be payable in increasing monthly installments over a period of 60 months.

The Asset Purchase Agreement is attached to this Proxy Statement as Appendix A. We encourage you to read the Asset Purchase Agreement carefully. Our Board of Directors has unanimously approved the Asset Purchase Agreement, which is the binding legal agreement that governs the terms of the sale of our Molded Rubber Products Business.

Some of the key provisions of the Asset Purchase Agreement are as follows:

Representations and Warranties

The Asset Purchase Agreement contains customary representations and warranties of the parties relating to, among other things, their authority to enter into the Asset Purchase Agreement and the condition of the Molded Rubber Products Business. For a more detailed description of the representations and warranties of each of the parties, please see page 19.

Covenants

The Asset Purchase Agreement contains customary covenants of the parties, including agreements by Green Tech Products to conduct the Molded Rubber Products Business in accordance with ordinary past practices and to refrain from certain actions between the time of signing the Asset Purchase Agreement and the closing of the sale of the Molded Rubber Products Business, and our agreement to use commercially reasonable efforts to solicit stockholder proxies approving the sale of the Molded Rubber Products Business.

Indemnification

The Asset Purchase Agreement provides that each party will indemnify the other for any losses incurred as a result of, among other things, breaches of representations, warranties and covenants, subject in certain circumstances to specified dollar and time limitations. However, Green Tech Products will not be obligated to indemnify IKH with respect to any representation or warranty in the Asset Purchase Agreement to the extent that Green Tech Products’ management team or employees knew or should have known that such representation or warranty is or might be inaccurate.

Conditions to Closing

The obligations of the parties to complete the sale of the Molded Rubber Products Business are subject to certain customary closing conditions, including, among other things:

Termination

The Asset Purchase Agreement may be terminated by:

Transaction Expenses

The parties to the Asset Purchase Agreement will pay their own expenses.

Certain Material Federal and State Income Tax Consequences (see page 22)

The sale of assets contemplated by the Asset Purchase Agreement may be a transaction taxable to us for United States federal and state income tax purposes. However, we believe any taxable gain on a federal or state tax basis would be offset against our current year losses from operations plus available net operating loss carry forwards, as currently reflected on our consolidated federal and state income tax returns.

The sale of assets contemplated by the Asset Purchase Agreement will not be a taxable event for our stockholders under applicable United States federal income tax laws.

Accounting Treatment (see page 22)

We will record the sale of the Molded Rubber Products Business in accordance with generally accepted accounting principles in the United States. Upon completion of the disposition, we will recognize a gain or loss for financial statement purposes equal to the net proceeds (the sum of the purchase price, including all liabilities assumed, less the expenses of the sale) less the book value of the assets sold. 

Regulatory Approvals (see page 22)

We are not aware of any federal or state regulatory requirements that must be complied with or approvals that must be obtained to complete the sale of the Molded Rubber Products Business, other than the filing of this Proxy Statement with the Securities Exchange Commission. If any additional approvals or filings are required, we will use our commercially reasonable efforts to obtain those approvals and make any required filings before completing the transactions contemplated by the Asset Purchase Agreement.

No Changes in the Rights of Stockholders (see page 23)

There will be no change in the rights of our stockholders as a result of the sale of the Molded Rubber Products Business.

No Appraisal Rights (see page 23)

Our stockholders do not have appraisal rights under the Delaware General Corporation Law in connection with the sale of the Molded Rubber Products Business.

Required Vote (see page 23)

Our Board of Directors believes that the sale of substantially all the assets of the Molded Rubber Products Business does not constitute a sale of “all or substantially all” of our assets for purposes of Section 271 of the Delaware General Corporate Law, and accordingly, our Board of Directors believes that approval of our stockholders is not required as a matter of Delaware law. The analysis of whether the sale of substantially all the assets of the Molded Rubber Products Business is subject to Section 271 is, however, inherently fact-driven and, if a court of competent jurisdiction were asked to determine whether Section 271 applied, its analysis would depend, among other things, on its views on the relative fair market value of the assets sold as compared to the fair market value of the assets retained following the transaction. To eliminate any uncertainty, Green Tech Products and IKH agreed that the transaction would be conditioned upon an approval of our stockholders. Our Board of Directors has determined to seek the affirmative vote of the holders of a majority of the shares of our common stock issued and outstanding as of the Record Date, so that such approval that would meet the requirements of Section 271 if Section 271 applied. Our Board of Directors also considered such approval to be a matter of good corporate governance. Because the transaction will be subject to stockholder approval by the stockholder vote that would otherwise be required if we were to sell all or substantially all of our assets, we believe that stockholder approval of the sale of substantially all the assets of the Molded Rubber Products Business would ensure that the transaction has satisfied the requirements of Section 271 if a court of competent jurisdiction ever determined that Section 271 applied to such transaction.

The affirmative vote of the holders of a majority of the shares of our common stock outstanding as of the record date for the Special Meeting is therefore required to approve the sale of the Molded Rubber Products Business. For this purpose, abstentions, broker “non-votes” and shares not represented at the Special Meeting will have the same effect as a vote “AGAINST” the sale of the Molded Rubber Products Business. Properly executed proxies that do not contain voting instructions will be voted “FOR” the approval of the sale of the Molded Rubber Products Business.

Based in part on the determination of the full Board of Directors, the Compensation Committee of our Board of Directors has determined that the sale of substantially all the assets of the Molded Rubber Products Business does not represent a sale of all or substantially all of our assets for purposes of our 2005 Stock Option Plan, as amended, any awards issued thereunder, or any severance or similar agreements we have with any of our employees. Accordingly, we will not deem the transaction to be an event that triggers the acceleration of vesting of stock options, restricted stock or restricted stock units, or the payment of severance, alone (a “single-trigger”) or in combination with a termination of service (a “double-trigger”). It is possible, however, that one or more employees will disagree with such conclusion and initiate legal action to receive benefits that would be available if the sale of substantially all the assets of the Molded Rubber Products Business were deemed a sale of all or substantially of our assets and other conditions set forth in the applicable plan or agreement were satisfied. Similarly, we do not believe that the sale of substantially all the assets of the Molded Rubber Products Business represents the sale of all or substantially all of our assets for purposes of certain promissory notes that become due and payable upon the sale or other disposition of all or substantially all of our assets. It is possible, however, that one or more note holders will disagree with such conclusion and initiate legal action to recover the principal amount of such notes, together with all accrued interest and costs of collection. We cannot assure you that we would prevail in any such actions.

None of our executive officers has any agreement or understanding concerning any type of compensation (whether present, deferred, or contingent) that is based on or otherwise relates to the completion of the sale of the assets of the Molded Rubber Products Business and that has not been waived. Accordingly, we are not requesting an advisory vote of our stockholders with respect to any such compensation.

Recommendation of our Board of Directors Regarding the Sale of the Molded Rubber Products Business (see page 24)

For the reasons described above, our Board of Directors has determined that the proposed sale of the Molded Rubber Products Business is in the best interests of the Company and our stockholders. Accordingly, our Board of Directors has unanimously approved the proposed sale of the Molded Rubber Products Business and Asset Purchase Agreement and unanimously recommends to our stockholders that they vote “FOR” approval of Proposal No. 1: Approval of the Sale of the Molded Rubber Products Business.

Proposal No. 2 Amend our Restated Certificate of Incorporation to increase the number of authorized shares of our common stock from 60,000,000 to 100,000,000

Purpose (see page 25)

As of May 31, 2011, there were 36,034,908 shares of our common stock issued and outstanding, and we had reserved approximately 9,871,088 additional shares for future issuance. These reserved shares include: 5,898,500 shares for issuance upon exercise of awards granted under our 1993 Stock Option Plan, 1996 Non-Employee Director Stock Option Plan, 2005 Stock Option Plan, 874,746 shares for issuance upon exercise of other stock options and stock purchase warrants and 3,097,842 shares for issuance upon the conversion of certain convertible promissory notes.

The Board of Directors believes that the authorized common stock should be increased to provide sufficient shares for such corporate purposes as may be determined by the Board of Directors. If this proposal is approved, the Board of Directors will have the authority to issue approximately 54,090,000 additional shares of common stock as of May 31, 2011, not including shares already reserved for issuance, as described above, without further stockholder approval.

Required Stockholder Vote to Approve the Increase in our Authorized Capital Stock (see page 26)

The affirmative vote of the holders of a majority of the shares of our common stock issued and outstanding as of the Record Date is required in order to approve the proposal to increase the number of authorized shares of common stock from 60,000,000 to 100,000,000 shares. For this purpose, abstentions, broker “non-votes” and shares not represented at the Special Meeting will have the same effect as a vote “AGAINST” the increase. Properly executed proxies that do not contain voting instructions will be voted “FOR” the approval of the proposal to increase the number of authorized shares of common stock.

Recommendation of our Board of Directors (see page 26)

Our Board of Directors believes that the increase in the number of authorized shares of common stock is in the best interests of our Company and our stockholders. Accordingly, our Board of Directors unanimously recommends to our stockholders that they vote “FOR” approval of Proposal No. 2: Approval of the amendment to our Restated Certificate of Incorporation to increase the number of authorized shares of our common stock from 60,000,000 to 100,000,000.

Proposal No. 3: Adjournment of the Special Meeting

Purpose (see page 26)

In the event there are not sufficient votes present, in person or by proxy, at the Special Meeting to approve the sale of the Molded Rubber Products Business or the increase in the number of authorized shares of common stock, our chief executive officer, acting in his capacity as chairperson of the meeting, may propose an adjournment of the Special Meeting to a later date or dates to permit further solicitation of proxies.

Required Stockholder Vote to Approve the Adjournment Proposal (see page 26)

Approval of Proposal No. 3 will require that the number of votes cast in favor of the proposal exceed the number of votes cast against it. Assuming the presence of a quorum, abstentions, broker “non-votes” and shares not represented at the Special Meeting will have no effect on Proposal No. 3: Adjournment.

Recommendation of our Board of Directors (see page 26)

Our Board of Directors unanimously recommends that our stockholders vote “FOR” approval of Proposal No. 3 to adjourn the Special Meeting, if necessary to obtain the requisite number of proxies to approve Proposal No. 1 and/or Proposal No. 2.

QUESTIONS AND ANSWERS ABOUT THE SPECIAL MEETING AND RELATED PROPOSALS

Why am I receiving this Proxy Statement and proxy card?

What will happen if the proposed sale of the Molded Rubber Products Business is not approved?

If we are unable to successfully complete the sale of our Molded Rubber Products Business we intend to close the Molded Rubber Products Business, liquidate Green Tech Products’ assets and use the net proceeds to satisfy as much of Green Tech Products’ obligations as possible.

Does the Board of Directors recommend that I vote on the proposals to be considered and voted upon at the Special Meeting?

Our Board of Directors unanimously recommends that you vote your shares:

How do I vote?

If your shares are registered directly in your name with our transfer agent, then, after carefully reading and considering the information contained or referred to in this Proxy Statement, including the Appendices, you may either (i) complete, sign and date your proxy card and voting instructions and return them in the enclosed postage-paid envelope or (ii) vote in person at the Special Meeting. Please vote your shares as soon as possible so that your shares will be represented at the Special Meeting.

If your shares are held of record by a broker or other nominee, the nominee will vote your shares only if you provide instructions on how to vote. Please consult your broker or nominee for voting instructions and tell that person how you would like him or her to vote your shares. If you do not tell your broker or other nominee how to vote, your shares will not be voted.

THE SPECIAL MEETING

Time, Date and Place; Matters to be Considered

The Special Meeting will be held on July 29, 2011, at 10:00 a.m. local time, at the offices of Morse, Barnes-Brown & Pendleton, P.C., Reservoir Place, 1601 Trapelo Road, Suite 205, Waltham, Massachusetts, 02451. At the Special Meeting, stockholders will be asked to consider and vote upon each of the proposals and conduct such other business as may properly come before the Special Meeting and any adjournment thereof.

Voting and Record Date

The Board of Directors has fixed May 31, 2011, as the record date (the “Record Date”) for determining holders of shares of our common stock that are entitled to receive notice of and to vote at the Special Meeting. Each holder of record of shares of our voting stock on the Record Date is entitled to cast one vote per share, in person or by a properly executed proxy, with respect to the approval of the proposals and any other matter to be submitted to a vote of our stockholders at the Special Meeting. At May 31, 2011, there were 36,034,908 shares of common stock outstanding.

Approval of Proposal No. 1 and Proposal No. 2 will each require the affirmative vote of the holders of a majority of the shares of our common stock issued and outstanding as of the Record Date. Therefore, abstentions, broker “non-votes” and shares not represented at the Special Meeting will have the same effect as votes against Proposal No. 1 and Proposal No. 2. Approval of Proposal No. 3 requires that the number of votes cast in favor of the proposal exceed the number of votes cast against it. Assuming the presence of a quorum, abstentions, broker “non-votes” and shares not represented at the Special Meeting will have no effect on Proposal No 3.

The Board of Directors has unanimously approved each of the proposals and recommends that stockholders vote “FOR” the approval of each of the proposals. We are seeking requisite stockholder approval of each of the proposals.

A complete list of stockholders entitled to vote at the Special Meeting will be available at least 10 days before the Special Meeting for examination by any stockholder, for any purpose germane to the Special Meeting, during ordinary business hours at the principal executive offices of the Company. The list will also be available at the Special Meeting.

Quorum

The required quorum for the transaction of business at the Special Meeting is a majority of the shares of our common stock issued and outstanding on the Record Date and entitled to vote at such meeting. Broker non-votes and shares that are voted “FOR” or “AGAINST” a proposal or marked “ABSTAIN” are treated as being present at the Special Meeting for purposes of establishing a quorum.

Abstentions and Broker Non-Votes

Broker “non-votes” and the shares of voting stock as to which a stockholder abstains are included for purposes of determining whether a quorum of shares of voting stock is present at a meeting. A broker “non-vote” occurs when a nominee holding shares of voting stock for the beneficial owner does not vote on a particular proposal because the nominee does not have discretionary voting power with respect to that item and has not received instructions from the beneficial owner. Proposals 1, 2 and 3 are non-discretionary items, which means that a nominee may not vote on either proposal without instructions from the beneficial owner. Since each of Proposals 1 and 2 requires the affirmative vote of the holders of a majority of our issued and outstanding voting stock entitled to vote at the Special Meeting, abstentions and broker “non-votes” have the effect of votes “AGAINST” Proposals 1 and 2. Since Proposal 3 requires that the number of votes cast in favor of the proposal exceed the number of votes cast against it, assuming the presence of a quorum, abstentions and broker “non-votes” will have no effect on Proposal 3.

Brokerage Accounts

If any of your shares are held in the name of a brokerage firm, bank, bank nominee or other institution, only it can vote such shares and only upon receipt of your specific instructions.

Proxies

Our Board of Directors is asking for your proxy. Giving your proxy means you authorize the named proxies to vote your shares at the Special Meeting in the manner you direct. You may vote for or against the proposals or abstain from voting. All shares of common stock that are represented at the Special Meeting by properly executed proxies received by us prior to or at the Special Meeting, and not duly and timely revoked, will be voted at the Special Meeting in accordance with the choices marked thereon by the stockholders. If no choice is marked, the shares represented by each proxy will be voted FOR approval of each of the proposals. At the time that this Proxy Statement was mailed to stockholders, we were not aware that any other matters not referred to herein would be presented for action at the Special Meeting. If any other matters properly come before the Special Meeting, the persons designated in the proxy intend to vote the shares represented thereby in accordance with their best judgment.

Any proxy given pursuant to this solicitation may be revoked by the person giving it at any time before it is voted. Proxies may be revoked by (i) filing with our Corporate Secretary at or before the taking of the vote at the Special Meeting, a written notice of revocation bearing a later date than the proxy; (ii) duly executing a later-dated proxy relating to the same shares and delivering it to our Corporate Secretary before the taking of the vote at the Special Meeting; or (iii) attending the Special Meeting and voting in person (although attendance at the Special Meeting will not in and of itself constitute a revocation of a proxy).

Attendance at the Special Meeting

Only holders of common stock may attend the Special Meeting. If you wish to attend the Special Meeting in person but you hold your shares through someone else, such as a stockbroker, you must bring proof of your ownership and photo identification at the Special Meeting. For example, you could bring an account statement showing that you beneficially owned shares of our common stock as of the record date as acceptable proof of ownership.

Costs of Solicitation

We will pay for the entire cost of soliciting proxies. In addition to these mailed proxy materials, our directors and employees may also solicit proxies in person, by telephone or by other means of communication. Directors and employees will not be paid any additional compensation for soliciting proxies. We may reimburse brokerage firms, banks and other agents for the cost of forwarding proxy materials to beneficial owners. We may also engage a professional proxy solicitation firm to assist in the proxy solicitation and, if so, will pay such solicitation firm customary fees plus expenses.

FORWARD LOOKING STATEMENTS

Statements in this Proxy Statement that are “forward-looking statements” are based on our beliefs as well as assumptions made by us using information currently available. The words “anticipate,” “believe,” “estimate,” “expect,” “intend,” “will,” “should” and similar expressions, as they relate to us, are intended to identify forward-looking statements. Such statements reflect our current views with respect to future events, are subject to certain risks, uncertainties and assumptions, and are not guaranties of future performance. Should one or more of these risks or uncertainties materialize, or should underlying assumptions prove incorrect, actual results may vary materially from those described herein as anticipated, believed, estimated, expected, intended or using other similar expressions. These forward looking statements are based on our current estimates and assumptions and, as such, involve uncertainty and risk. Actual results could differ materially from projected results because of factors such as:

There are representations and warranties contained in the Asset Purchase Agreement that is attached as an appendix and described herein which were made by the parties to each other as of specific dates. The assertions embodied in these representations and warranties were made solely for purposes of the Asset Purchase Agreement and may be subject to important qualifications and limitations agreed to by the parties in connection with negotiating its terms. Moreover, certain representations and warranties may not be accurate or complete as of any specified date because they are subject to a contractual standard of materiality that is different from certain standards generally applicable to stockholders or were used for the purpose of allocating risk between the parties rather than establishing matters as facts. Therefore, you should not rely on the representations and warranties contained in the Asset Purchase Agreement as statements of factual information.

We do not assume any obligation to update information contained in this document, except as required by federal securities laws. Although this Proxy Statement may remain available on our website or elsewhere, its continued availability does not indicate that we are reaffirming or confirming any of the information contained herein. Neither our website nor its contents are a part of this Proxy Statement.

RISK FACTORS

You should carefully consider the special risk considerations described below as well as other information provided to you or referenced in this Proxy Statement in deciding how to vote on the proposed sale of the Molded Rubber Products Business and the proposed amendment to our Restated Articles of Incorporation to increase our authorized shares. The special risk considerations described below are not the only ones we face. For a discussion of additional risk considerations, we refer to you the documents we file from time to time with the Securities and Exchange Commission, particularly our Form 10-K for the fiscal year ended September 30, 2010 and our Form 10-Q for the fiscal quarter ended March 31, 2011, which are attached as Appendix B and Appendix C hereto. Additional considerations not presently known to us or that we currently believe are immaterial may also impair our business operations. If any of the following special risk considerations actually occur, our business, financial condition or results of operations could be materially adversely affected, the value of our common stock could decline, and you may lose all or part of your investment.

Special Risk Considerations Regarding the Proposed Sale of the Molded Rubber Products Business

If we fail to complete the sale of the Molded Rubber Products Business, our business may be harmed.

We cannot assure you that the sale of the Molded Rubber Products Business will be completed. As a result of our announcement of the sale of the Molded Rubber Products Business, third parties may be unwilling to enter into material agreements with respect to our Molded Rubber Products Business. New or existing customers may prefer to enter into agreements with our competitors who have not expressed an intention to sell their business because customers may perceive that such relationships are likely to be more stable. If we fail to complete the proposed sale of the Molded Rubber Products Business, we intend to close the Molded Rubber Products Business, liquidate Green Tech Products’ assets and use the net proceeds to satisfy as much of Green Tech Products’ obligations as possible.

You will not receive any of the proceeds from the sale of the Molded Rubber Products Business.

The purchase price for the assets of the Molded Rubber Products Business will be paid directly to us or our creditors. Therefore, no proceeds will be received by our stockholders as a result of the sale.

The Asset Purchase Agreement may expose us to contingent liabilities.

Under the Asset Purchase Agreement, our Green Tech Products subsidiary is required to indemnify IKH for the breach or violation of any representation, warranty or covenant made by Green Tech Products in the Asset Purchase Agreement, subject to certain limitations and up to a maximum of the total purchase price. In addition, subject to certain procedural requirements, IKH will have the right to offset the amount of any indemnification claims it may have against any amounts due and payable under the $100,000 promissory note IKH will deliver to us at the closing. Significant indemnification claims by IKH could have a material adverse effect on our ability to collect the amounts due to us under that promissory note.

Even if our stockholders approve the sale of the Molded Rubber Products Business, we cannot be sure when, or even if, the sale of the Molded Rubber Products Business will be completed.

The completion of the sale of the Molded Rubber Products Business is subject to the satisfaction of a number of conditions, including, among others, the requirement that we obtain stockholder approval of the sale and the requirement that IKH obtain funds sufficient to complete the transaction on terms and conditions satisfactory to it. In addition, IKH may terminate the agreement if we do not cure breaches, if any, of a material provision of the Asset Purchase Agreement within five business days of notice of such breach. We cannot guarantee that Green Tech Products and IKH will be able to meet the closing conditions of the Asset Purchase Agreement. If Green Tech Products is unable to meet the closing conditions, IKH is not obligated to purchase the Molded Rubber Products Business. We also cannot be sure that other circumstances, for example, a material adverse event, will not arise that would allow IKH to terminate the Asset Purchase Agreement prior to closing. If the asset sale is not approved or does not close, our Board of Directors will be forced to evaluate other alternatives, which are expected to be less favorable to us than the proposed sale of the Molded Rubber Products Business.

Even if we complete the sale of the Molded Rubber Products Business, we will remain responsible for certain pending litigation involving that business.

We received notice on January 26, 2011 that the Orland Unified School District, Orland, California had filed a complaint in the Glen County Superior Court in the State of California against Green Tech Products and its subsidiaries, GreenMan Technologies and several other unrelated parties, including one of the two senior managers of Green Tech Products who is a co-owner of IKH, seeking general monetary damages, exemplary damages, other statutory damages, attorneys’ fees and costs and other equitable remedies relating to their dissatisfaction with the installation of several playground equipment and tile projects during 2008. Under the Asset Purchase Agreement, IKH is not assuming any of the liabilities potentially associated with this litigation, and all of such of liabilities, if any, will remain our responsibility. We have also agreed to defend and to indemnify the senior manager against any expenses he may incur in connection with this litigation. We believe the case is without merit and that we have substantial defenses against the plaintiff’s claims, and we intend to contest the matter vigorously. If, however, the plaintiff is ultimately successful in winning damages in excess of any insurance coverage that may be available to us, it could have a material adverse effect on our business and financial condition. As of the date of this proxy statement, Green Tech Products is not party to any other litigation.

PROPOSAL NO. 1

APPROVAL OF THE SALE OF THE MOLDED RUBBER PRODUCTS BUSINESS

General

Pursuant to the Asset Purchase Agreement, we will sell to IKH our Molded Rubber Products Business, which includes all of the assets of our Green Tech Products, Inc. subsidiary. Upon consummation of the proposed sale of the Molded Rubber Products Business, ownership of Green Tech Products’ assets will be transferred to IKH. The sale of the Molded Rubber Products Business will constitute the sale of substantially all of our Molded Rubber Products Business assets.

The Parties

GreenMan Technologies, Inc.

We were originally founded in 1992 and have operated as a Delaware corporation since 1995. Our business is comprised of two business segments, our dual fuel conversion operations (American Power Group) and our molded recycled rubber products operations (Green Tech Products). On June 17, 2009, we signed an exclusive license agreement with American Power Group, Inc. under which we acquired the exclusive worldwide right to commercialize their patented dual fuel alternative energy technology and July 27, 2009, we purchased substantially all of their remaining operating assets, including their name but excluding the dual fuel patent. If the sale of the Molded Rubber Products Business is completed, our sole business will be to operate American Power Group’s dual fuel conversion operations.

Green Tech Products, Inc.

Green Tech Products, Inc. (formerly known as Welch Products, Inc.) is an Iowa corporation wholly owned by GreenMan since October 2007. Green Tech Products’ molded recycled rubber products operations specialize in the design, development and manufacturing of branded recycled products and services that provide schools and municipalities with environmentally responsible products to create safer work and play environments.

Irish Knight Holdings, L.L.C.

Irish Knight Holdings, L.L.C. is an Iowa limited liability company co-owned by two senior managers of Green Tech Products. IKH’s principal executive offices are located at 1701 Fernwood Lane, Algonquin, Illinois 60102, and its phone number is 847-917-3958.

Reasons for the Sale of the Molded Rubber Products Business

As of March 31, 2011, we had $751,983 in cash, cash equivalents and restricted certificates of deposit and a working capital deficiency of $1,855,118. We have incurred substantial losses from operations over the past ten fiscal quarters since divesting our tire recycling business in November 2008. Green Tech Products has incurred operating losses aggregating approximately $5.9 million since we acquired the company on October 1, 2007. In addition, Green Tech Products has experienced declining revenues during the past two fiscal years despite ongoing investments in sales and marketing initiatives intended to promote Green Tech Products’ patented products and establish market presence. The sale of the Molded Rubber Products Business will permit us to focus all of our corporate resources on advancing our dual fuel conversion business, which we believe has much greater potential for scalability given the millions of diesel engines operated globally today. We believe the sale of the Molded Rubber Products Business and the terms of the Asset Purchase Agreement are in the best interests of our stockholders.

Background of the Sale of the Molded Rubber Products Business

In response to continuing significant operating losses and declining revenues our Board of Directors determined it to be in the best interests of shareholder value to exit the Molded Rubber Products Business and to devote all of our corporate resources to advancing American Power Group’s dual fuel conversion business. Accordingly, on March 8, 2011, our Board adopted a plan to commence an immediate effort to identify potential buyers for Green Tech Products’ business and/or evaluate other strategic alternatives.

During the past several months we have met with numerous parties who had expressed an interest in our Molded Rubber Products Business, but who were unwilling to submit an offer to purchase the business. Given these facts and as an alternative to closing down and liquidating the assets of Green Tech Products, we approached two members of Green Tech Products’ senior management team to discuss their interest in acquiring the Molded Rubber Products Business. After several discussions with these individuals, we received a non-binding proposal from IKH, a company formed by the two individuals, to purchase the Molded Rubber Products Business. Based on the consideration offered by IKH, including the assumption of significant liabilities from Green Tech Products, and the unwillingness of other prospective purchasers to submit offers, our Board of Directors believed IKH would be a suitable buyer for our Molded Rubber Products Business. Our Board of Directors also believed, due to IKH’s management’s extensive knowledge of the molded rubber products industry, that there was a high probability that IKH would be able to finance and complete the acquisition.

On April 4, 2011 our Board of Directors met to discuss the status of the potential transaction with IKH and approved the execution of a non-binding letter of intent for the purchase of the Molded Rubber Products Business by IKH.

During April 2011 we provided a draft agreement to IKH that covered the basic terms of the proposed transaction. Throughout the following weeks, we negotiated the terms of the Asset Purchase Agreement with IKH and on June 9, 2011 we finalized the terms of the Asset Purchase Agreement.

On June 10, 2011, our Board of Directors convened a meeting to review the final Asset Purchase Agreement and the proposed sale of the Molded Rubber Products Business. During the meeting, management informed the Board that, based on management’s estimates, the value to be realized from liquidating the Molded Rubber Products Business assets would be insufficient to satisfy all remaining obligations of the business and that IKH was willing to assume or satisfy all of such obligations, other than potential liabilities associated with certain pending litigation. Based on this information and after additional discussions, the Board of Directors determined that entering into the Asset Purchase Agreement and completing the proposed sale of the Molded Rubber Products Business to IKH were in the best interests of the Company and our stockholders. Our Board of Directors and Green Tech Products’ board of directors then approved (i) the Asset Purchase Agreement, (ii) the related transaction agreements, and (iii) the proposed sale of our Molded Rubber Products Business to IKH on the terms set forth in those agreements, and authorized management to execute the Asset Purchase Agreement and the other transaction agreements on our behalf.

On June 13, 2011, Green Tech Products executed the Asset Purchase Agreement with IKH and we publicly announced the agreement on June 14, 2011.

Effect of the Sale of the Molded Rubber Products Business

If our stockholders approve the sale of the Molded Rubber Products Business, we will seek to complete the sale. The cash proceeds of the proposed sale will not be substantial. However, the sale will relieve us of material liabilities and other obligations, and will allow us to focus both management’s attention and our corporate resources to grow our dual fuel conversion business model domestically as well as world-wide and to pursue additional business opportunities that are intended to increase shareholder value.

The Asset Purchase Agreement

The following is a description of the material terms of the Asset Purchase Agreement. The following description does not purport to describe all of the terms and conditions of the Asset Purchase Agreement. The full text of the Asset Purchase Agreement is attached to this proxy statement as Appendix A and is incorporated by reference. You are urged to read the Asset Purchase Agreement in its entirety because it is the legal document that governs the terms and conditions of the proposed sale of the Molded Rubber Products Business.

Structure

Our Molded Rubber Products Business is operated by our wholly owned subsidiary, Green Tech Products, Inc. The transaction is structured as the sale of substantially all of the assets of Green Tech Products, Inc. to IKH. The assets of our Molded Rubber Products Business will be sold free of liens and encumbrances other than certain assumed liabilities.

Effective Time

The closing of the transaction is anticipated to occur as promptly as practicable after we obtain stockholder approval and satisfy all other conditions to Closing.

Purchase Price

As consideration for the sale of substantially all the assets of the Molded Rubber Products Business, the purchase price will be (i) the assumption of substantially all Green Tech Products’ liabilities (which were approximately $1,100,000 at March 31, 2011, including all of Green Tech Products’ loans from Great Western Bank, in an amount not to exceed $221,427 (inclusive of all principal, accrued but unpaid interest and other charges, fees and obligations), which will be repaid to such bank directly by IKH), but excluding potential liabilities associated with certain pending litigation; (ii) a $50,000 stock inventory credit toward the purchase of products and services from IKH, which credit may be applied during the first nine months after completion of the sale; and (iii) a promissory note in the principal amount of $100,000, which note would bear interest at the rate of 6% per annum and would be payable in increasing monthly installments over a period of 60 months.

The Asset Purchase Agreement is attached to this Proxy Statement as Appendix A. We encourage you to read the Asset Purchase Agreement carefully. Our Board of Directors has unanimously approved the Asset Purchase Agreement, which is the binding legal agreement that governs the terms of the sale of our Molded Rubber Products Business.

Excluded Assets and Retained Liabilities

Certain assets and liabilities related to the Molded Rubber Products Business are excluded from the sale and include:

Conduct of Molded Rubber Products Business Prior to the Closing

Green Tech Products has agreed to customary covenants that require Green Tech Products, among other things, from the date of the Asset Purchase Agreement through the closing of the Transaction:

Representations and Warranties

The Asset Purchase Agreement contains customary representations and warranties made by Green Tech Products to IKH and by IKH to Green Tech Products for purposes of allocating the risks associated with the sale of the Molded Rubber Products Business. The assertions embodied in the representations and warranties made by Green Tech Products are qualified by information set forth in a confidential disclosure schedule that was delivered in connection with the execution of the Asset Purchase Agreement. While we do not believe that the disclosure schedule contains information that securities laws require us to publicly disclose, other than information that is being disclosed in this Proxy Statement, the disclosure schedule may contain information that modifies, qualifies and creates exceptions to the representations and warranties set forth in the Asset Purchase Agreement. Accordingly, you should not rely on any of these representations and warranties as characterizations of the actual state of facts, since they may be modified in important respects by the underlying disclosure schedule. Moreover, information concerning the subject matter of the representations and warranties may have changed since the date of the Asset Purchase Agreement, which subsequent information may or may not be fully reflected in the disclosure schedule we delivered to IKH at signing and which may not be delivered by us until the consummation of the sale of the Molded Rubber Products Business.

The representations and warranties made by the parties must be accurate as of the date of the Asset Purchase Agreement and as of the time of the closing, except for those representations and warranties that relate to a specific date, which must be accurate as of such date.

Closing Conditions

IKH’s Conditions. IKH’s obligation to complete the proposed sale of the Molded Rubber Products Business is subject to certain conditions, including among other things:

Our Conditions. Our obligation to complete the proposed sale of the Molded Rubber Products Business is subject to certain conditions, including, among other things:

Non-Competition and Non-Solicitation

In addition, for a period of three years from the completion of the sale, we have agreed that neither we nor any of our affiliates will, directly or indirectly, induce or attempt to induce any employee of IKH to leave their employ, or otherwise solicit the employment of any such employee of IKH, hire any such employee or in any way interfere with the relationship between IKH and any of such employees, induce or attempt to induce any customer of IKH to cease doing business with IKH or in any way interfere with the relationship between IKH and any of its customers or business relations, or solicit the business of any then existing customer of IKH.

Termination

The Asset Purchase Agreement may be terminated at any time prior to the date of the Closing by:

Expenses

We and IKH are each responsible for our respective costs and expenses that we or IKH incur in connection with the proposed sale of the Molded Rubber Products Business.

Indemnification

Under the Asset Purchase Agreement, Green Tech Products has agreed to indemnify IKH and its representatives and other related parties against any losses, liabilities, damages or expenses, including reasonable attorneys’ fees and expenses, which arise from or in connection with: (a) any breach or inaccuracy of any representation or warranty made by us in the Asset Purchase Agreement or in any exhibits or schedules thereto or in any certificate or document delivered by us at the Closing, with each representation and warranty being read for this purpose without regard to any “materially,” “Material Adverse Effect,” “in any material respect” or similar exception or qualifier contained in any such representation or warranty; (b) any breach or nonperformance of any covenant or obligation made by Green Tech Products in the Asset Purchase Agreement or any other agreement contemplated by the Asset Purchase Agreement; (c) any acts or omissions of Green Tech Products relating to the operations, ownership, condition or conduct of the Molded Rubber Products Business prior to the closing, whether or not disclosed in any schedule to the Asset Purchase Agreement; or (d) any liabilities of the Molded Rubber Products Business retained by Green Tech Products; provided that Green Tech Products’ liability for such indemnification claims for breaches of representations and warranties will not exceed the purchase price, and provided further that Green Tech Products will not be required to indemnify IKH for breaches of representations and warranties unless and until the total claims for such indemnification, in the aggregate, equal or exceed $50,000 and only in the amount in excess of $50,000. Further, Green Tech Products will not be obligated to indemnify IKH with respect to any representation or warranty in the Asset Purchase Agreement to the extent that Green Tech Products’ management team or employees knew or should have known that such representation or warranty is or might be inaccurate.

IKH has agreed to indemnify us and our representatives and other related parties against any losses, liabilities, damages or expenses, including reasonable attorneys’ fees and expenses, which arise from or in connection with: (a) any breach or inaccuracy of any representation or warranty made by IKH in the Asset Purchase Agreement or in any exhibits or schedules thereto or in any certificate or document delivered by IKH at the Closing, with each representation and warranty being read for this purpose without regard to any “materially,” “Material Adverse Effect,” “in any material respect” or similar exception or qualifier contained in any such representation or warranty; or (b) any breach or nonperformance of any covenant or obligation made by IKH in the Asset Purchase Agreement or any other agreement contemplated by the Asset Purchase Agreement; provided that the liability of IKH for such indemnification claims for breaches of representations and warranties shall not exceed an amount equal to the purchase price, and provided further that IKH will not be required to indemnify us for breaches of representations and warranties unless and until the total claims for such indemnification, in the aggregate, equal or exceed $50,000 and only in the amount in excess of $50,000. Further, IKH will not be obligated to indemnify us with respect to any representation or warranty in the Asset Purchase Agreement to the extent that we had actual knowledge that such representation or warranty is inaccurate. In addition, subject to certain procedural requirements, IKH will have the right to offset the amount of any indemnification claims it may have against any amounts due and payable under the $100,000 promissory note IKH will deliver to us at the closing.

All claims for indemnification, whether by Green Tech Products or by IKH, must be made within 18 months after the completion of the sale, except that (i) indemnification claims with respect to Green Tech Products’ representations and warranties relating to certain intellectual property, environmental matters and tax matters may be made at any time prior to the third month after the expiration of the applicable statute of limitations, and (ii) indemnification claims with respect to representations and warranties relating to the respective parties’ due organization, qualification to do business, authority to consummate the transaction and title to the assets of the Molded Rubber Products Business may be made indefinitely at any time following the closing.

Certain Material Federal and State Income Tax Consequences

This is a summary of the principal material United States federal and state income tax consequences relating to the proposed sale of assets.

The proposed sale of assets may be a transaction taxable to us for United States federal and state income tax purposes. We will recognize taxable income equal to the amount realized on the sale in excess of our tax basis in the assets sold. The amount realized on the sale will consist of the cash we receive in exchange for the assets sold, the stock inventory credit plus the amount of related liabilities assumed by IKH. Although the sale of the assets may result in a taxable gain to us, we believe any taxable gain on a federal and state tax basis would be offset against our current year losses from operations plus available net operating loss carry forwards, as currently reflected on our consolidated federal and state income tax returns.

The proposed sale of the assets will not be a taxable event for our stockholders under applicable United States federal income tax laws.

This summary does not consider the effect of any applicable foreign, state, local or other tax laws nor does it address tax consequences applicable to stockholders that may be subject to special federal income tax rules. This summary is based on the current provisions of the Internal Revenue Code, existing, temporary, and proposed Treasury regulations thereunder, and current administrative rulings and court decisions. Future legislative, judicial or administrative actions or decisions, which may be retroactive in effect, may affect the accuracy of any statements in this summary with respect to the transactions entered into or contemplated prior to the effective date of those changes. 

Accounting Treatment

We will record the sale of the Molded Rubber Products Business in accordance with generally accepted accounting principles in the United States. Upon completion of the disposition, we will recognize a gain for financial reporting purposes equal to the net proceeds (the sum of the purchase price, including all liabilities assumed, less the expenses of the sale) less the book value of the assets sold.

Regulatory Approvals

We are not aware of any federal or state regulatory requirements that must be complied with or approvals that must be obtained to complete the sale of the Molded Rubber Products Business, other than the filing of this proxy statement with the Securities and Exchange Commission. If any additional approvals or filings are required, we will use our commercially reasonable efforts to obtain those approvals and make any required filings before completing the transactions.

No Changes to the Rights of Stockholders

There will be no change in the rights of our stockholders as a result of the sale of the Molded Rubber Products Business.

No Appraisal Rights

Our stockholders do not have appraisal rights under the Delaware General Corporation Law in connection with the sale of the Molded Rubber Products Business.

Required Vote

Our Board of Directors believes that the sale of substantially all the assets of the Molded Rubber Products Business does not constitute a sale of “all or substantially all” of our assets for purposes of Section 271 of the Delaware General Corporate Law, and accordingly, our Board of Directors believes that approval of our stockholders is not required as a matter of Delaware law. The analysis of whether the sale of substantially all the assets of the Molded Rubber Products Business is subject to Section 271 is, however, inherently fact-driven and, if a court of competent jurisdiction were asked to determine whether Section 271 applied, its analysis would depend, among other things, on its views on the relative fair market value of the assets sold as compared to the fair market value of the assets retained following the transaction. To eliminate any uncertainty, Green Tech Products and IKH agreed that the transaction would be conditioned upon an approval of our stockholders. Our Board of Directors has determined to seek the approval of the holders of a majority of the shares of our common stock issued and outstanding as of the Record Date, so that such approval that would meet the requirements of Section 271 if Section 271 applied. Our Board of Directors also considered such approval to be a matter of good corporate governance. Because the transaction will be subject to stockholder approval by the stockholder vote that would otherwise be required if we were to sell all or substantially all of our assets, we believe that stockholder approval of the sale of substantially all the assets of the Molded Rubber Products Business would ensure that the transaction has satisfied the requirements of Section 271 if a court of competent jurisdiction ever determined that Section 271 applied to such transaction.

The affirmative vote of the holders of a majority of the shares or our common stock issued and outstanding as of the Record Date is therefore required to approve the sale of the Molded Rubber Products Business. For this purpose, abstentions, broker “non-votes” and shares not represented at the Special Meeting will have the same effect as a vote “AGAINST” the sale of the Molded Rubber Products Business. Properly executed proxies that do not contain voting instructions will be voted “FOR” the approval of the sale of the Molded Rubber Products Business.

Based in part on the determination of the full Board of Directors, the Compensation Committee of our Board of Directors has determined that the sale of substantially all the assets of the Molded Rubber Products Business does not represent a sale of all or substantially all of our assets for purposes of our 2005 Stock Option Plan, as amended, any awards issued thereunder, or any severance or similar agreements we have with any of our employees. Accordingly, we will not deem the transaction to be an event that triggers the acceleration of vesting of stock options, restricted stock or restricted stock units, or the payment of severance, alone (a “single-trigger”) or in combination with a termination of service (a “double-trigger”). It is possible, however, that one or more employees will disagree with such conclusion and initiate legal action to receive benefits that would be available if the sale of substantially all the assets of the Molded Rubber Products Business were deemed a sale of all or substantially of our assets and other conditions set forth in the applicable plan or agreement were satisfied. We cannot assure you that we would prevail in any such action. Similarly, we do not believe that the sale of substantially all the assets of the Molded Rubber Products Business represents the sale of all or substantially all of our assets for purposes of certain promissory notes that become due and payable upon the sale or other disposition of all or substantially all of our assets. It is possible, however, that one or more note holders will disagree with such conclusion and initiate legal action to recover the principal amount of such notes, together with all accrued interest and costs of collection.

None of our executive officers has any agreement or understanding concerning any type of compensation (whether present, deferred, or contingent) that is based on or otherwise relates to the completion of the sale of the assets of the Molded Rubber Products Business and that has not been waived. Accordingly, we are not requesting an advisory vote of our stockholders with respect to any such compensation.

Recommendation of Our Board of Directors Regarding the Sale of the Molded Rubber Products Business

For the reasons described above, our Board of Directors has determined that the proposed sale of the Molded Rubber Products Business pursuant to the Asset Purchase Agreement is in the best interests of the Company and our stockholders. Accordingly, our Board of Directors has unanimously approved the proposed sale of the Molded Rubber Products Business and recommends to our stockholders that they vote “FOR” approval of Proposal No. 1.

Our Board of Directors unanimously recommends that you vote “FOR” the approval of the proposed sale of the Molded Rubber Products Business pursuant to the Asset Purchase Agreement by completing and returning the enclosed proxy or by completing and returning the voting instructions that you receive from the broker or other nominee that holds your shares.

PROPOSAL NO. 2

PROPOSAL TO INCREASE AUTHORIZED SHARES OF COMMON STOCK

Purpose

The Board of Directors has recommended to the stockholders that our Company amend its Restated Certificate of Incorporation to increase the number of authorized shares of common stock from 60,000,000 to 100,000,000 shares. The text of the proposed amendment is set forth in Appendix D to this Proxy Statement.

As of May 31, 2011, there were 36,034,908 shares of our common stock issued and outstanding, and we had reserved approximately 9,871,088 additional shares for future issuance. These reserved shares include: 5,898,500 shares for issuance upon exercise of awards granted under our 1993 Stock Option Plan, 1996 Non-Employee Director Stock Option Plan, 2005 Stock Option Plan, 874,746 shares for issuance upon exercise of other stock options and stock purchase warrants and 3,097,842 shares for issuance upon the conversion of certain convertible promissory notes.

If this proposal is approved, the Board of Directors will have the authority to issue approximately 54,090,000 additional shares of common stock as of May 31, 2011, not including shares already reserved for issuance, as described above, without further stockholder approval. The Board of Directors believes that the increase in the number of authorized shares of common stock is in the best interests of our Company and our stockholders. The Board of Directors believes that the authorized common stock should be increased to provide sufficient shares for such corporate purposes as may be determined by the Board of Directors. These purposes may include, among others, the issuance of common stock to facilitate potential mergers or acquisitions, raising capital or acquiring technology rights through the sale of stock, and/or attracting or retaining valuable employees by the issuance of stock options. Except as described above or elsewhere in this proxy statement, we have no plans, understandings, commitments, agreements or undertakings concerning the issuance of any such additional shares. The Board of Directors, however, considers the authorization of additional shares of common stock advisable to ensure prompt availability of shares for issuance should the occasion arise.

Under the Delaware General Corporation Law, the Board of Directors generally may issue authorized but unissued shares of common stock without further stockholder approval. The Board of Directors does not currently intend to seek stockholder approval prior to any future issuance of additional shares of common stock, unless stockholder action is required in a specific case by applicable law, the rules of any exchange or market on which our securities may then be listed or traded, or our Restated Certificate of Incorporation or By-Laws then in effect. Frequently, opportunities arise that require prompt action, and we believe that delay necessitated for stockholder approval of a specific issuance could be detrimental to our Company and our stockholders.

The additional shares of common stock authorized for issuance pursuant to this proposal will have the rights and privileges which the presently outstanding shares of common stock possess under our Restated Certificate of Incorporation. Shares of our common stock, including the additional shares proposed for authorization, do not have preemptive or similar rights. The increase in authorized shares would not affect the terms or rights of holders of existing shares of common stock. The voting, dividend and liquidation rights of the holders of common stock, however, may be subordinate to the rights of the holders of the any preferred stock which may be issued from time to time. All outstanding shares of common stock would continue to have one vote per share on all matters to be voted on by the stockholders, including the election of directors.

The issuance of any additional shares of common stock by our Company may, depending on the circumstances under which those shares are issued, reduce stockholders’ equity per share and, unless additional shares are issued to all stockholders on a pro rata basis, will reduce the percentage ownership of common stock of existing stockholders. We expect, however, to receive consideration for any additional shares of common stock issued, thereby reducing or eliminating any adverse economic effect to each stockholder of such dilution.

The authorized but unissued shares of common stock could be used to make a change in control of our Company more difficult. For example, such shares could be sold to purchasers who might side with the Board of Directors in opposing a takeover bid that the Board determines not to be in the best interests of our Company and our stockholders. Such a sale could have the effect of discouraging an attempt by another person or entity, through the acquisition of a substantial number of shares of our common stock, to acquire control of our Company since the issuance of new shares could be used to dilute the stock ownership of the acquirer. Our Restated Certificate of Incorporation and By-Laws contain certain provisions, including the grant of authority to the Board of Directors to issue up to 1,000,000 shares of preferred stock in one or more series (with such rights and preferences as the Board may determine), without the approval of stockholders, and certain provisions relating to the calling of stockholder meetings and the conduct of such meetings, that may be considered to have an anti-takeover effect. We are not aware of any pending or threatened efforts to obtain control of our Company, and the Board of Directors has no current intention to use the additional shares of common stock to impede a takeover attempt or to propose any additional anti-takeover measures in future proxy solicitations.

Required Stockholder Vote to Approve the Adjournment Proposal

Approval of the amendment to increase the number of authorized shares of common stock will require the affirmative vote of the holders of a majority of our common stock issued and outstanding as of the Record Date. Abstentions will have the same effect as a vote against the proposal; broker non-votes will have no outcome on the vote.

Recommendation of our Board of Directors

The Board of Directors recommends a vote for the approval of the amendment to our Restated Certificate of Incorporation to increase the number of authorized shares of Common Stock from 60,000,000 to 100,000,000.

PROPOSAL 3

ADJOURNMENT

Purpose

In the event there are not sufficient votes present, in person or by proxy, at the Special Meeting to approve the sale of the Molded Rubber Products Business or the increase in the number of authorized shares of our common stock, our chief executive officer or other officer, acting in his capacity as chairperson of the meeting, may propose an adjournment of the Special Meeting to a later date or dates to permit further solicitation of proxies.

Required Stockholder Vote to Approve the Adjournment Proposal

Approval of the adjournment proposal will require that the number of votes cast in favor of the proposal exceed the number of votes cast against it. Assuming the presence of a quorum, abstentions, broker “non-votes” and shares not represented at the Special Meeting will have no effect on the adjournment proposal.

Recommendation of our Board of Directors

Our Board of Directors unanimously recommends that our stockholders vote “FOR” approval of Proposal No. 3 to adjourn the Special Meeting, if necessary to obtain the requisite number of proxies to approve Proposal No. 1 and/or Proposal No. 2.

1.      Summary of Significant Accounting Policies

Business

Our Green Tech Products’ molded recycled rubber products operations specialize in the design, development and manufacturing of branded recycled products and services that provide schools and municipalities with environmentally responsible products to create safer work and play environments. Green Tech’s Duromat Extended Life™ playground safety tiles are manufactured with a patented “cold-cure” process that allows high quality crumb rubber tiles to have a unique long life, even in extreme hot and cold temperatures.

Basis of Presentation

The financial statements contained herein follow the principles and policies more fully described in the Company’s audited consolidated financial statements for the year ended September 30, 2010 and 2009 attached hereto as Appendix C, and the Company’s unaudited consolidated financial statements for the three and six month periods ended March 31, 2011 attached hereto as Appendix D, which have been prepared in accordance with accounting principles generally accepted in the United States of America. The unaudited financial statements are derived from the Company’s historical consolidated financial statements and are designed to present the Molded Rubber Products Business as if it was not part of the consolidated operations of the Company for the periods presented. Management believes that the unaudited financial statements presented herein have been prepared in accordance with generally accepted accounting principles and meet Regulation S-X requirements.

Management Estimates

The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the amounts of revenues and expenses recorded during the reporting period. Actual results could differ from those estimates. Such estimates relate primarily to the estimated lives of property and equipment other intangible assets, the valuation reserve on deferred taxes, the value of our lease settlement obligation and the value of equity instruments issued. The amount that may be ultimately realized from assets and liabilities could differ materially from the values recorded in the accompanying financial statements for the periods presented.

Cash Equivalents

Cash equivalents include short-term investments with original maturities of three months or less.

Accounts Receivable

Accounts receivable are carried at original invoice amount less an estimate made for doubtful accounts. Management determines the allowance for doubtful accounts by regularly evaluating past due individual customer receivables and considering a customer’s financial condition, credit history, and the current economic conditions. Individual accounts receivable are written off when deemed uncollectible, with any future recoveries recorded as income when received.

Product Inventory

Inventory consists primarily of crumb rubber and is valued at the lower of cost or market on the first-in first-out (FIFO) method. Finished goods primarily consist of molded products and playground equipment. Inventory consists of the following:

Property, Plant and Equipment

Property, plant and equipment are stated at cost. Depreciation and amortization expense is provided on the straight-line method. Expenditures for maintenance, repairs and minor renewals are charged to expense as incurred. Significant improvements and major renewals that extend the useful life of equipment are capitalized. Property, plant and equipment consists of:

Revenue Recognition

We have primarily two sources of revenue: (1) product revenue which is earned from the sale of molded rubber products and playground equipment and (2) installation revenue which is earned from the installation of molded products and playground equipment. Revenues from product sales are recognized when the products are shipped and collectability is reasonably assured. Revenues derived from installations of our products are recognized when the installation is complete.

Shipping and Handling Fees and Costs

Shipping and handling fees and costs billed to customers and incurred by the Company are reported gross in revenues and cost of sales in the consolidated statements of operations and comprehensive income.

Income Taxes

Deferred tax assets and liabilities are recorded for temporary differences between the financial statement and tax bases of assets and liabilities using the currently enacted income tax rates expected to be in effect when the taxes are actually paid or recovered. A deferred tax asset is also recorded for net operating loss and tax credit carry forwards to the extent their realization is more likely than not. The deferred tax expense for the period represents the change in the net deferred tax asset or liability from the beginning to the end of the period.

Product Warranty Costs

Our molded rubber products operations typically offer a five-year warranty for all of our tile and playground equipment. We provide for the estimated cost of product warranties for both our recycled rubber products at the time product revenue is recognized. Factors that affect our warranty reserves include the number of units sold, historical and anticipated rates of warranty repairs, and the cost per repair.

The following table provides the detail of the change in our product warranty accrual as of:

Intangible Assets

In accordance with SFAS No. 142, “Goodwill and Other Intangible Assets” we review intangibles for impairment annually, or more frequently if an event occurs or circumstances change that would more likely than not reduce the fair value of our intangible assets below their carrying value.

In conjunction with the Green Tech Products acquisition in 2007 we recognized $2,289,939 of goodwill, $735,000 associated with long term contractual relationships acquired and $130,000 to acquired patents. The long term contractual relationships are being amortized on a straight line basis over an estimated useful life ranging from 48 to 60 months and the patents are being amortized on a straight line basis over an estimated useful life of 60 months. During the fiscal 2008 and 2009 Green Tech Products incurred significant operating losses per year, has had negative cash flow from operations and stagnant revenue growth. As of September 30, 2009 management determined that based on several fair value determination scenarios the estimated fair value of Green Tech Products was below its carrying value including goodwill and therefore recorded a non-cash impairment loss of $2,289,939 at September 30, 2009.

Long-Lived Assets

Long-lived assets to be held and used are analyzed for impairment whenever events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. We evaluate at each balance sheet date whether events and circumstances have occurred that indicate possible impairment. If there are indications of impairment, we use future undiscounted cash flows of the related asset or asset grouping over the remaining life in measuring whether the assets are fully recoverable. In the event such cash flows are not expected to be sufficient to recover the recorded asset values, the assets are written down to their estimated fair value. Long-lived assets to be disposed of are reported at the lower of carrying amount or fair value of asset less the cost to sell.
