Proposal No. 2

Introduction

We are asking you to approve the issuance and sale, through a private placement, to Fletcher International, Ltd., or Fletcher, of (1) 1,418,842 shares of our common stock, issued to Fletcher on January 29, 2004, for an aggregate purchase price of $10 million, or $7.048 per share, and (2) rights to purchase up to an additional $28 million of our common stock and in certain instances up to 2,700,000 shares of Plug Power Inc. common stock owned by us. We consummated the Fletcher private placement on January 29, 2004 and amended its terms on May 4, 2004. The private placement is subject to the terms and conditions outlined in the Agreement between the Company and Fletcher dated as of January 26, 2004, amended as of May 4, 2004 and the Certificate of Additional Investment Rights issued by the Company on May 4, 2004.

The first paragraph of the Introduction is a directorbrief summary of various private corporations. Mr. O'Connor originally became a Directorsome of the principal terms of the private placement as amended. A more detailed description is contained below in this Proxy Statement. This summary and the more detailed description below are qualified by reference to the Agreement between Fletcher and the Company, when heas amended, and the Certificate of Additional Investment Rights issued by the Company on May 4, 2004 (which was selectedissued in exchange for the Certificate of Additional Investment Rights issued on January 29, 2004). The Agreement between Fletcher and the Company and the Certificate of Additional Investment Rights issued on January 29, 2004 are attached as exhibits to our Form 8-K, filed with the SEC on January 27, 2004. The amendments to the Agreement between Fletcher and the Company, and the Certificate of Additional Investment Rights issued by Masco Corporationthe Company on May 4, 2004 are attached as exhibits to our Form 8-K, filed with the SEC on May 4, 2004.

Reasons for the Transaction

The principal reason for the private placement is to provide us with additional working capital to continue to invest in and support MTI MicroFuel Cells in its designeedevelopment and commercialization of Direct Methanol Micro Fuel Cells (DMFCs) as a future power source for portable electronic devices. The Company is committed to the commercialization of DMFCs. One of the most significant challenges facing the commercialization of any new technology is the ability to finance that technology through commercialization. The Company needed sufficient cash reserves available to help assure that it would have sufficient cash to fund MTI Micro through to commercialization of DMFCs. We believe that the best option for us is to obtain that additional financing, in part, through the private placement. The proceeds of the Fletcher private placement have been and will continue to be used to fund the operations of MTI Micro and for other general corporate purposes.

Any exercises of the additional investment rights could result in sales of our common stock at prices that are below the market for our common stock at the time of exercise and could result in substantial dilution to our shareholders. In addition, the number of shares of Plug Power common stock Fletcher may purchase and the exercise price for those shares are subject to fluctuation based on the Company'smarket price of our common stock and the market price of Plug Power common stock. Accordingly, Fletcher may, in certain instances, purchase shares of Plug Power common stock either at a price below the fair market value of such shares, thereby reducing the value of our assets, or even if based on the market price of Plug Power shares, at a price which we would otherwise not desire to sell such shares.

Background of the Transaction

Our Board of Directors pursuantand management considered a number of different financing alternatives prior to entering into the Agreement with Fletcher. During 2003, management met with more than six private equity groups and investment bankers specializing in private placements. We also evaluated other types of financing, including the sale of Plug Power shares, the sale of MTI Micro common shares and acquisitions of companies with substantial cash balances. Several of these financing alternatives generated proposals, which were discussed by our Board of Directors, but which the Board of Directors ultimately determined were not in the best interest of the shareholders.

Fletcher presented us with a term sheet initially in November 2003 and began its due diligence of the Company. After extensive negotiations, Fletcher and the Company agreed to the principal deal terms in January 2004. At a meeting of the Board of Directors on January 13, 2004, the Board approved the private placement with Fletcher. On January 26, 2004, the Company and Fletcher signed definitive agreements entered intoand the Company issued a press release the next day. We filed the press release with the SEC on January 27, 2004 on Form 8-K and included copies of the Agreement and the Certificate of Additional Investment Rights.

On May 4, 2004, we amended our agreement with Fletcher. The agreement, as amended, includes a change in the exercise price for the rights to purchase additional shares of MTI common stock to a fixed price of $6.34 per share from, in the original agreement, $7.05 per share until December 31, 2005 and the lesser of $7.05 per share or a variable price in 2006. The change to a fixed price substantially reduces the potential for shareholder dilution if shares had been purchased at a variable price in 2006. The price remains subject to adjustment upon the occurrence of certain limited events. The agreement, as amended, also includes:

• an increase in the rights to purchase additional shares of MTI common stock to $28 million from $26 million;

• a reduction in Fletcher's right to purchase Plug Power Inc. (NASDAQ:PLUG) common stock escrowed by the Company to a maximum of 2,700,000 shares from a maximum of 3,000,000 shares;

• an extension of the exercise period for the right to purchase Plug Power Inc. common stock to one or more purchases between June 1, 2005 and December 31, 2006 from a one-time purchase in June of 2005;
• an extension of MTI's ability to withdraw Plug Power Inc. common stock from escrow through December 31, 2006 instead of through June 30, 2005; and
• an extension of the exercise period for the right to invest the first $8 million in MTI's common stock to any time prior to December 31, 2004 from any time prior to ninety business days after the effective date of MTI's registration statement.

The amendments to the Agreement between Fletcher and the Company, and the Certificate of Additional Investment Rights issued by the Company on May 4, 2004 are attached as exhibits to our Form 8-K, filed with the SEC on May 4, 2004.

Why We Need Shareholder Approval

As a NASDAQ listed company, we are subject to the Marketplace Rules of the National Association of Securities Dealers. Under Marketplace Rule 4350(i), we must obtain shareholder approval for a transaction involving the sale or issuance of shares of common stock (or securities convertible or exercisable for common stock) at a price below the book value or market value of such shares, where the amount of stock being issued is equal to 20% or more of our common stock outstanding prior to such issuance or represents 20% or more of the voting power outstanding prior to such issuance. Our amended agreement with Fletcher requires that we seek shareholder approval of all shares of our common stock issued or issuable to Fletcher. In the event we obtain such shareholder approval, Fletcher's exercise of its additional investment rights may result in the issuance of more than 20% of our common stock outstanding on January 26, 2004 at a price that may be below the market value. Accordingly, we are seeking shar eholder approval in order to satisfy Rule 4350(i) and the terms of our amended agreement with Fletcher.

The amended Fletcher agreement provides that prior to obtaining shareholder approval, Fletcher may not exercise its additional investment rights if such exercise would result in issuances to Fletcher in the private placements (which include all prior issuances) of more than 19.99% of our common stock outstanding on January 26, 2004. If we do not obtain shareholder approval, Fletcher will be entitled to a "net basis settlement" as more fully described under the caption "Net Basis Settlement" below.

Private Placement

On January 29, 2004, we issued to Fletcher, in a private placement (1) 1,418,842 shares of our common stock for an aggregate purchase price of $10 million, or $7.048 per share, and (2) rights to purchase up to an additional $26 million of our common stock and in certain instances up to 3,000,000 shares of Plug Power common stock owned by us, which rights are referred to herein as the additional investment rights. We have been and will continue to use the proceeds of the private placement primarily to support the operations of MTI Micro and for other general corporate purposes. We filed a registration statement with the SEC on February 3, 2004 for 6,384,790 shares, as required by our agreement with Fletcher, to permit Fletcher to re-sell the shares of our common stock issued to Fletcher and any shares of our common stock that Fletcher may have acquired in the future upon exercise of its additional investment rights or upon the occurrence of certain other events.

On May 4, 2004, we amended our agreement with Fletcher. The agreement, as amended, includes a change in the exercise price for the rights to purchase additional shares of MTI common stock to a fixed price of $6.34 per share from, in the original agreement, $7.05 per share until December 31, 2005 and the lesser of $7.05 per share or a variable price in 2006. The change to a fixed price substantially reduces the potential for shareholder dilution if shares had been purchased at a variable price in 2006. The price remains subject to adjustment upon the occurrence of certain limited events. The agreement, as amended, also includes:

• an increase in the rights to purchase additional shares of MTI common stock to $28 million from $26 million;
• a reduction in Fletcher's right to purchase Plug Power Inc. (NASDAQ:PLUG) common stock escrowed by the Company to a maximum of 2,700,000 shares from a maximum of 3,000,000 shares;
• an extension of the exercise period for the right to purchase Plug Power Inc. common stock to one or more purchases between June 1, 2005 and December 31, 2006 from a one-time purchase in June of 2005;
• an extension of MTI's ability to withdraw Plug Power Inc. common stock from escrow through December 31, 2006 instead of through June 30, 2005; and
• an extension of the exercise period for the right to invest $8 million to any time prior to December 31, 2004 from any time prior to ninety business days after the effective date of the registration statement.

Additional Investment Rights

The amended additional investment rights provide Fletcher with the right, but not the obligation, to purchase up to an additional $8 million of our common stock at any time prior to December 31, 2004, at a price per share equal to $6.34. In addition, in the event Fletcher exercises in full such $8 million investment right, Fletcher shall have the right, but not the obligation, to purchase, in a single purchase or multiple purchases, up to an additional $20 million of our common stock at any time prior to December 31, 2006 at a price per share equal to $6.34, which date may be extended in the event that we have not satisfied our contractual obligations with respect to the registration for resale of common stock issued or issuable to Fletcher.

The table below illustrates the number of shares Fletcher would receive upon exercise of its $20 million additional investment right at a price per share equal to $6.34 (such exercise price is subject to adjustment as described under "Adjustment Provisions") .Note that our amended agreement with Fletcher provides that the maximum number of shares we could potentially issue to Fletcher is 8,330,411 shares.

	Shares Issuable in
Purchase Price	Exchange for $20
MTI Stock	Million Investment
$6.34	3,154,575

In connection with the 1992amended private placement agreement, the Company has reduced the number of shares of Plug Power it has deposited into escrow to 2,700,000 shares, a reduction of 300,000 shares. Commencing immediately after the SEC declares effective the registration statement relating to shares of our common stock that Fletcher owns (or may acquire), we continue to have the right to have 250,000 of such shares released from escrow to us, on a monthly basis, in the event that on any day during such month, the prevailing price of our common stock exceeds $6.343 (which price may have been adjusted to reflect stock splits, recombinations, stock dividends or the like). If Fletcher does not exercise its right to purchase the first additional $8 million of our common stock, all of such Plug Power shares will be released from escrow to us. If, however, Fletcher does exercise such right, then at any time, on one or multiple occasions, from June 1, 2005 to December 31, 2006, Fletcher may exercise its right to purchase from us a number of shares of Plug Power common stock totaling $10,000,000 divided by the prevailing price per share of Plug Power common stock, but only to the extent of the number of shares remaining in escrow.

The exercise price for the Plug Power investment right is $10,000,000 less the positive difference between $18,000,000 and the product of the sum of 1,418,842 and the quantity of shares purchased in the exercise of the first $8 million of additional investment rights multiplied by the prevailing price per share of our common stock on the date Fletcher elects to exercise such right, all divided by the quotient obtained by dividing 10,000,000 by the prevailing price of Plug Power common stock on the date Fletcher elects to exercise such right. As used herein, a prevailing price is the average of the daily volume-weighted average price per share of common stock during the sixty-business-day period ending three days prior to the date Fletcher elects to exercise such right, provided however that the price may not exceed the average of the daily volume-weighted average prices for any ten business days within such sixty-business-day period. Each of the above referenced per share exercise prices for the addition al investment rights was subject to adjustment as described below under "Adjustment Provisions."

As a result of this exercise price calculation, we may be required to sell shares of Plug Power at a discount to prices we would otherwise obtain in sales at market prices. The table below illustrates such potential discounts based on assumed decreases in our stock price from $6.00 (which, for the purposes of this illustration, serves as an approximation of the price of our common stock as of March 11, 2004, the date we filed Amendment No.1 to our Registration Statement on Form S-3), and an assumed price of Plug Power stock at the time of exercise. Note that Fletcher's right to purchase Plug Power shares is conditioned on the exercising of Fletcher's first $8 million of additional investment rights.

Adjustment Provisions

Our amended agreement with Fletcher also provides that we may be required to issue additional shares to Fletcher, reduce the exercise prices described above for the additional investment rights and/or extend the investment term upon the occurrence of certain events (each as more fully described below) including:

• a restatement of our financial results,
• a change in control of our company,
• a future issuance of our capital stock at a price less than $7.048 as it relates to the initial $10 million investment and $6.34 as it relates to all additional investments, or

• our failure to maintain the effectiveness of the registration statement relating to shares of our common stock that Fletcher owns or may acquire, as well as our failure to satisfy the other requirements relating to registration.

Restatement

In the event we restate any portion of our financial statements prior to January 29, 2005, or prior to the first anniversary of the closing of any additional investment, as the case may be, the exercise price for the additional investment rights will be adjusted to equal the prevailing price of our common stock sixty days after we restate our financial statements. In addition, with respect to any investments made prior to the time of the restatement, Fletcher will receive additional shares of common stock such that all such investments will have been effectively made at such adjusted exercise price.

Change in Control

In the event of a change of control of our Company prior to sixty days after the expiration of the additional investment term, we may have to issue additional shares of our common stock to Fletcher and the additional investment rights (including the right to purchase the Plug Power shares) may be accelerated. If the consideration per share paid to our shareholders in the change of control transaction is less than twice the amount of the price per share paid by Fletcher for any of its investments pursuant to the agreement with Fletcher or the certificate of additional investment rights, then we must issue to Fletcher a number of shares of our common stock such that all of its investments will have been effectively made at a price per share equal to such per share change of control consideration multiplied by 0.5. In addition, if our shareholders have not approved the transaction with Fletcher prior to a change of control of our Company, Fletcher may make a net basis settlement with respect to its addi tional investment rights. The mechanics of a net basis settlement are described below under "Net Basis Settlement and Shareholder Approval."

Dilutive Issuances

If on or prior to December 31, 2004 we issue any equity securities at a price below $7.048 as it relates to the initial $10 million investment and $6.34 as it relates to all additional investments, then we must issue to Fletcher a number of additional shares to reflect the number of shares it would have acquired if its purchase price was such lower price and adjust the exercise price for the additional investment rights to such lower price. In addition, if after December 31, 2004 and ending December 31, 2006 we issue any equity securities at a price below $7.048 as it relates to the initial $10 million investment and $6.34 as it relates to any additional investments which have been made, the exercise price for the additional investment rights shall be adjusted to provide Fletcher "weighted average" anti-dilution protection and we must issue to Fletcher a number of additional shares such that all prior investments will have been effectively made at such adjusted exercise price.

Registration Obligations

In the event we fail to satisfy our contractual obligations to register for resale shares of common stock issued or issuable to Fletcher, then we must issue to Fletcher a number of additional shares to reflect the number of shares it would have acquired if its purchase price was based on the actual exercise price reduced by five percent for each month in which Masco sold 1,730,000we fail to satisfy our obligations and adjust the exercise price for the additional investment rights to such lower price. In addition, such failure will result in an extension of the investment term for each day we fail to satisfy our registration obligations. These registration obligations include, among other things, maintaining the effectiveness of registration statements.

Net Basis Settlement and Shareholder Approval

We are obligated under the agreement with Fletcher to seek shareholder approval of the issuance of more than 19.99 percent of our common stock pursuant to our transactions with Fletcher. In the event we do not obtain such shareholder approval, or in the event a change in control of our Company occurs prior to obtaining such shareholder approval, and as a result of the exercise of the additional investment rights, we would have issued more than 19.99 percent of our common stock, Fletcher will be entitled to a "net basis settlement", whereby it receives a certain number of shares of common stock, without any cash payment by Fletcher, representing the difference between the market value of the additional investment rights as of three business days prior to the date Fletcher elects to exercise such additional investment rights and the investment purchase price. Such number of shares shall equal the quotient obtained by dividing "X" by the closing price of our common stock on the date three days prior to Fletcher exercising an additional investment right (such price is referred to herein as the net basis price), where "X" is the product of (1) the additional investment amount, divided by the additional investment exercise price, multiplied by (2) the amount by which the net basis price exceeds the additional investment exercise price.

Other

The agreement also provides Fletcher certain other rights including, but not limited to, indemnification rights with respect to (1) breaches of representations, warranties and covenants contained in the agreements with Fletcher, and (2) misstatements in or omissions from the prospectus and the registration statement relating to shares of our common stock that Fletcher owns or may acquire.

On October 9, 2003, the Board of Directors delegated the authority for nominations to the Board of Directors to the Compensation Committee, which has been renamed the Compensation and Nominating Committee. On April 28, 2004, the Board of Directors delegated the authority for governance to the Compensation and Nominating Committee, which has been renamed the Compensation, Nominating and Governance Committee.

In looking for Directors, the Board focused on the candidate's credentials, business savvy, concern for the Company's shareholders and since 2003, that such Directors met the director independence standards of the Nasdaq National Market System. It is anticipated that the Compensation, Nominating and Governance Committee will continue to follow these standards.

A shareholder wishing to submit such a recommendation should send a letter to the Secretary of whichthe Company at 431 New Karner Rd., Albany New York, 12205.
