REPORT OF INDEPENDENT AUDITORS

To the Board of Directors and Shareholders

of Mechanical Technology Incorporated

In our opinion, the accompanying consolidated balance sheets and the related consolidated statements of operations, shareholders' equity and comprehensive income (loss) and of cash flows present fairly, in all material respects, the financial position of Mechanical Technology Incorporated, at December 31, 2003 and 2002, and the results of their operations and their cash flows for the years ended December 31, 2003 and 2002, the three month period ended December 31, 2001, and for the year ended September 30, 2001, in conformity with accounting principles generally accepted in the United States of America. These financial statements are the responsibility of the Company's management; our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these statements in accordance with auditing standards generally accepted in the United States of America, which require that we plan and perform the audit to obtain reasonable assurance about whether the fi nancial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

As discussed in Note 1 to the financial statements, the Company adopted Statement of Financial Accounting Standards No. 142,Goodwill and Other Intangible Assets,on January 1, 2002, Emerging Issues Task Force Issue 00-19,Accounting for Derivative Financial Instruments Indexed to, and Potentially Settled in a Company's own Stock on June 30, 2001, and Financial Accounting Standards No. 133,Accounting for Derivative Instruments and Hedging Activities on October 1, 2000. Additionally, as discussed in Note 1, the Company changed its method of accounting for its investments in Plug Power Inc. and SatCon Technology Corporation on December 20, 2002 and July 1, 2002, respectively.

1. Accounting Policies

Principles of Consolidation

The consolidated financial statements include the accounts of the Company and its majority-owned subsidiaries. The equity method of accounting is used for holdings in entities over which the Company has significant influence, generally this represents common stock ownership or partnership equity of at least 20% and not more than 50%, or where the Company has the ability to exercise significant influence over operating and financial policies of the underlying entity. All significant intercompany transactions are eliminated in consolidation.

Minority interest in subsidiaries consists of equity securities issued by a subsidiary of the Company. No gain or loss was recognized as a result of the issuance of these securities, and the Company owned a majority of the voting equity of the subsidiary both before and after the transactions.

Under the equity method of accounting, the Company recognized its proportionate share of income or loss of holdings. Holdings' losses were generally recognized only to the extent of holdings. Changes in equity of holdings, other than income or loss, which changed the Company's proportionate interest in the underlying equity of holdings, were generally accounted for as changes in holdings and additional paid-in-capital. Non-monetary contributions to equity holdings were recorded at book value, and if the Company's calculated share of net assets of holdings exceeded the book value of non-monetary contributions, the difference was accounted for as a basis difference. Original differences between the Company's carrying amount of an equity holding and its calculated share of the holding's net assets were treated as an embedded difference if the Company's carrying amount was higher, or as a basis difference if lower. Until January 1, 2002, embedded differences were amortized into net income (loss) from hol dings generally over a five-year period while basis differences were generally not amortized due to the research and development nature of holdings. Upon an equity holdings' initial public offering, basis differences were eliminated in connection with the change in equity. Impairment was measured in accordance with the Company's Asset Impairment Policy.

Change in Year-End

On February 13, 2002, the Company changed its fiscal year-end from September 30 to December 31, effective with the calendar year beginning January 1, 2002. A three-month transition period from October 1, 2001

through December 31, 2001 (the "Transition Period") precedes the start of the 2002 fiscal year. "2001" refers to the year ended September 30, the Transition Period refers to the three months ended December 31, 2001, and "2003" and "2002" refer to the twelve months ended December 31. This new fiscal year made the Company's annual and quarterly reporting periods consistent with those used by Plug Power Inc. ("Plug Power") and permitted the Company to continue to account for its holdings in Plug Power on a timely basis through December 20, 2002, the date of its change in accounting for Plug Power from the equity method to the fair value method.

Change in Accounting for Holdings

SatCon Technology Corporation ("SatCon")

The Company's holdings in SatCon were accounted for on a one-quarter lag under the equity method of accounting from their acquisition date through

July 1, 2002. On July 1, 2002, the Company determined that it no longer had the ability to exercise significant influence over the operating and financial policies of SatCon as a result of waiving the Company's right to nominate and recommend directors to SatCon's board and our reduction

of ownership in SatCon and, therefore, accounted for its investment

in SatCon since July 1, 2002 using the fair value method as set forth in Statement of Financial Accounting Standards ("SFAS") No. 115,Accounting for Certain Debt and Equity Securities. The Company was no longer required to record its share of any losses from SatCon and the investment was carried at fair value, designated as available for sale and any unrealized holding gains or losses were included in stockholders' equity as a component of accumulated other comprehensive income (loss) until the investment was sold during 2003.

Plug Power

The Company's holdings in Plug Power were accounted for under the equity method of accounting from their acquisition date through December 20, 2002. On December 20, 2002, the Company determined that it no longer had the ability to exercise significant influence over the operating and financial policies of Plug Power as a result of its reduced ownership in Plug Power and, therefore, accounted for its investment in Plug Power since December 20, 2002 using the fair value method as set forth in SFAS No. 115,Accounting for Certain Debt and Equity Securities. The Company was no longer required to record its share of any losses from Plug Power and the holding was carried at fair value, designated as available for sale and any unrealized holding gains or losses were included in stockholders' equity as a component of accumulated other comprehensive income (loss).

Use of Estimates

The preparation of the consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Fair Value of Financial Instruments

The Company's financial instruments consist of cash and cash equivalents, marketable securities, accounts receivable, unbilled contract costs and fees, warrants to purchase shares of common stock and accounts payable. The estimated fair value of these financial instruments approximate their carrying values at December 31, 2003 and 2002. The estimated fair values have been determined through information obtained from market sources, where available, or Black-Scholes valuations.

Accounting for Derivative Instruments

On October 1, 2000, the Company adopted Statement of Financial Accounting Standards ("SFAS") No. 133,Accounting for Derivative Instruments and Hedging Activities,which establishes a new model for accounting for derivatives and hedging activities. It requires an entity to recognize all derivatives as either assets or liabilities in the statement of financial position and measure these instruments at fair value. Upon adoption of SFAS No. 133, the Company recorded an unrealized gain on its investment in derivatives, consisting of warrants to purchase SatCon and Beacon Power Corporation ("Beacon Power") common stock, in its results of operations as a cumulative effect of a change in accounting principle of $6.110 million, net of tax, to reflect the impact of adopting this accounting standard on October 1, 2000.

In September 2000, the Emerging Issues Task Force ("EITF") issued EITF Issue No. 00-19,Accounting for Derivative Financial Instruments Indexed to and Potentially Settled in, a Company's Own Stock, which requires

freestanding contracts that are settled in a company's own stock, including common stock warrants, to be designated as an equity instrument, asset or a liability. Under the provisions of EITF Issue No. 00-19, a contract designated as an asset or a liability must be carried at fair value, with any changes in fair value recorded in the results of

operations. A contract designated as an equity instrument must be included within equity, and no fair value adjustments are required. In accordance with EITF Issue No. 00-19, the Company determined that outstanding warrants as of September 30, 2001 to purchase 300,000 shares of the Company's common stock issued to SatCon should be designated as a liability. Effective June 30, 2001, all warrants designated as a liability must be recorded as a liability and therefore, the Company reclassified the warrants designated as a liability from equity to liabilities, which had a fair value on the issuance date of $3.678 million, using the Black Scholes option-pricing model.

Additionally on June 30, 2001, the Company recorded the warrants at the current fair value of $1.210 million, using the Black-Scholes option-pricing model, and recorded a $1.468 million gain, net of tax in its results of operations as a cumulative effect of a change in accounting principle. Effective December 28, 2001, the Company amended these warrants, removing the provisions providing the warrant holders with rights that rank higher than those of common stockholders. As a result of the amendment, these warrants meet the criteria of equity instruments in accordance with EITF Issue No. 00-19 and, therefore, the Company reclassified the value of these warrants to equity from liabilities.

MECHANICAL TECHNOLOGY INCORPORATED AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

The Company held or has outstanding the following derivative financial instruments:

Inventories

Inventories are stated at the lower of cost (first-in, first-out) or market.

Property, Plant, and Equipment

Property, plant and equipment are stated at cost and depreciated using primarily the straight-line method over their estimated useful lives:

Significant additions or improvements extending assets' useful lives are capitalized; normal maintenance and repair costs are expensed as incurred. The costs of fully depreciated assets remaining in use are included in the respective asset and accumulated depreciation accounts. When items are sold or retired, related gains or losses are included in net income.

Income Taxes

The Company accounts for taxes in accordance with SFAS No. 109,Accounting for Income Taxes, which requires the use of the asset and liability method of accounting for income taxes. Under the asset and liability method, deferred income taxes are recognized for the tax consequences of "temporary differences" by applying enacted statutory tax rates applicable for future years to differences between financial statement and tax bases of existing assets and liabilities. Under SFAS No. 109, the effect of tax rate changes on deferred taxes is recognized in the income tax provision in the period that includes the enactment date. The provision for taxes is reduced by investment and other tax credits in the years such credits become available. A valuation allowance is recorded to reduce the carrying amounts of deferred tax assets unless it is more likely than not that such assets will be realized.

Revenue Recognition

The Company recognizes revenue from product sales in accordance with Staff Accounting Bulletins ("SAB") No. 104,Revenue Recognition. Product revenue is recognized when there is persuasive evidence of an arrangement, delivery of the product to the customer or distributor has occurred, at which time title generally is passed to the customer or distributor, and the Company has determined that collection of a fixed fee is probable, all of which occur upon shipment of the product. If the product requires installation to be performed by the Company, all revenue related to the product is deferred and recognized upon the completion of the installation.

The Company performs funded research and development for government agencies and companies under cost reimbursement contracts, which generally require the Company to absorb up to 50% of the total costs incurred.  Cost reimbursement contracts provide for the reimbursement of allowable costs.  Revenues are generally recognized in proportion to the reimbursable costs incurred. When government agencies are providing funding they do not expect the government to be the only significant end user of the resulting products.  These contracts do not require delivery of products that meet defined performance specifications, but are best efforts arrangements to achieve overall research and development objectives. Included in accounts receivable are billed and unbilled work-in-progress on cost reimbursed contracts.

While the Company's accounting for these contract costs is subject to audit by the sponsoring entity, in the opinion of management, no material adjustments are expected as a result of such audits. Cost of

product revenue includes material, labor and overhead. Costs incurred in connection with funded research and development arrangements are included in funded research and product development expenses.

Deferred revenue consists of payments received from customers in advance of services performed, products shipped or installation completed.

Warranty

The Company records a warranty reserve at the time product revenue is recorded based on a historical rate. The reserve is reviewed during the year and is adjusted, if appropriate, to reflect new product offerings or changes in experience. Actual warranty claims are tracked by product.

Accounting for Goodwill and Other Intangible Assets

Intangible assets include patents and trade names. Effective January 1, 2002, with the adoption of SFAS No. 142,Goodwill and Other Intangible Assets, amortization of goodwill and intangible assets with indefinite lives ceased. Intangible assets with finite useful lives will continue to be amortized over those periods. Indefinite lived intangible assets will be tested for impairment annually, and will be tested for impairment between annual tests if an event occurs or circumstances change that would indicate that the carrying amount may be impaired. Definite lived assets are tested for impairment whenever events or circumstances indicate that a carrying amount of an asset may not be recoverable. An

impairment loss would be recognized when the carrying amount of an asset exceeds the estimated undiscounted cash flows used in determining the fair value of the asset. Then the amount of the impairment loss to be recorded is calculated by the excess of the assets carrying value over its fair value. Fair value is generally determined using a discounted cash flow analysis. Costs related to internally-developed intangible assets are expensed as incurred.

As a result of the adoption of this Statement, the Company stopped amortizing goodwill associated with its equity holdings in SatCon.

The Company recorded expense related to the amortization of goodwill associated with its holdings in SatCon of $0, $0, $688 and $2,755 thousand, respectively, during 2003, 2002, the Transition Period, and 2001, respectively. The Company has no intangible assets.

The Pro Forma effects of the Company adopting SFAS No. 142 as if SFAS No. 142 had been applied for all periods presented would be as follows:

Accounting for Impairment or Disposal of Long-Lived Assets

In August 2001, the Financial Accounting Standards Board ("FASB") issued SFAS No. 144, Accounting for the Impairment or Disposal of Long-Lived Assets, which supersedes SFAS No. 121, Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed Of, and the accounting and reporting provisions of Accounting Principles Board ("APB") Opinion No. 30. This Statement addresses financial accounting and reporting for the impairment or disposal of long-lived assets and was adopted as of January 1, 2002. This Statement specifies how impairment will be measured and how impaired assets will be classified in the financial statements.

Cash and Cash Equivalents

Cash and cash equivalents consist of cash and highly liquid short-term investments with original maturities of less than three months.

Securities Available for Sale

Management determines the appropriate classification of its investments in marketable securities at the time of purchase and reevaluates such determinations at each balance sheet date. Marketable securities for

which the Company does not have the intent or ability to hold to maturity are classified as available for sale. Securities available for sale are carried at fair value, with the unrealized gains and losses, net of income taxes, reported as a separate component of shareholders'

F-13

equity. The Company has had no investments that qualify as trading or held to maturity. Realized gains and losses are included in "Gain (loss) on sale of securities available for sale, net" in the Consolidated Statements of Operations. The cost of securities sold is based on the specific identification method.

Net (Loss) Income per Basic and Diluted Common Share

The Company reports net (loss) income per basic and diluted common share in accordance with SFAS No. 128,Earnings Per Share, which establishes standards for computing and presenting (loss) income per share. Basic (loss) income per share is computed by dividing net (loss) income attributable to common stockholders by the weighted-average number of common shares outstanding for the period. Diluted (loss) income per share reflects the potential dilution, if any, which would occur if securities or other contracts to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock that then shared in the (loss) income of the Company.

Stock Based Compensation

At December 31, 2003, the Company has two stock-based employee compensation plans, which are described more fully in Note 13. SFAS No.

123,Accounting for Stock-Based Compensation, requires the measurement of the fair value of stock options or warrants granted to employees to be included in the consolidated statement of operations or, alternatively, disclosed in the notes to consolidated financial statements. The Company accounts for stock-based compensation of employees under the intrinsic value method of APB Opinion No. 25,Accounting for Stock Issued to Employees, and related Interpretations and has elected the disclosure-only alternative under SFAS No. 123. The Company records the fair market value of stock options and warrants granted to non-employees in exchange for services in accordance with EITF No. 96-18,Accounting for Equity Instruments That Are Issued to Other Than Employees for Acquiring, or in Conjunction with Selling, Goods or Services, in the Consolidated Statement of Operations. The Company does not intend to adopt the transition provisions of SFAS No. 148,Accounting for Stock- Based Compensat ion- Transition and Disclosure.

The following table illustrates the effect on net (loss) income and (loss) earnings per share if the Company had applied the fair value recognition provisions of SFAS Statement No. 123,Accounting for Stock-Based Compensation, to stock-based employee compensation.

Advertising

The costs of advertising are expensed as incurred. Advertising expense was approximately $25, $37, $10 and $67 thousand in 2003, 2002, the Transition Period, and 2001, respectively.

Concentration of Credit Risk

Financial instruments that subject the Company to concentrations of credit risk principally consist of cash equivalents, marketable securities, trade accounts receivable and unbilled contract costs.

The Company's trade accounts receivable and unbilled contract costs and fees are primarily from sales to commercial customers and U.S. government and state agencies. The Company does not require collateral and has not historically experienced significant credit losses related to receivables or unbilled contract costs and fees from individual customers or groups

of customers in any particular industry or geographic area.

The Company deposits its cash and invests in marketable securities

primarily through commercial banks and investment companies. Credit exposure to any one entity is limited by Company policy.

Research and Development Costs

The Company expenses research and development costs as incurred.

Comprehensive Income (Loss)

Comprehensive income (loss) includes net income (loss), as well as changes in stockholders' equity, other than those resulting from investments by shareholders (i.e., issuance or repurchase of common shares and dividends).

Effect of Recent Accounting Pronouncements

In June 2001, FASB issued SFAS No. 143,Accounting for Asset Retirement Obligation. SFAS No. 143 requires entities to record the fair value of a liability for an asset retirement obligation in the period in which it is incurred. When the liability is initially recorded, an entity capitalizes a cost by increasing the carrying amount of the long-lived asset. Over time, the liability is accreted to its present value each period and the capitalized cost is depreciated over the useful life of the related asset. Upon settlement of the liability, an entity either settles the obligation for its recorded amount or incurs a gain or loss upon settlement.SFAS No. 143 is effective for fiscal years beginning after June 15, 2002. The adoption of this Statement did not have a material impact on the Company's consolidated financial statements.

In April 2002, the FASB issued SFAS No. 145,Rescission of FASB Statements Nos. 4, 44, and 64, Amendment of FASB Statement No. 13, and Technical Corrections. SFAS No. 145 rescinds SFAS No. 4,Reporting Gains and Losses from Extinguishment of Debt, and an amendment of that Statement, SFAS No. 44,Accounting for Intangible Assets of Motor Carriers, and SFAS No. 64,Extinguishment of DebtMade to Satisfy Sinking-Fund Requirements. This Statement amends SFAS No. 13,Accounting for Leases, to eliminate an inconsistency between the required accounting for sale-leaseback transactions. This Statement also amends other existing authoritative pronouncements to make various technical corrections, clarify meanings, or describes their applicability under changed conditions and is effective for fiscal years beginning after May 15, 2002. The adoption of this Statement did not have a material impact on the Company's consolidated financial statements.

In July 2002, the FASB issued SFAS No. 146,Accounting for Costs Associated with Exit or Disposal Activities. SFAS No. 146 addresses financial accounting and reporting for costs associated with exit or disposal activities and nullifies EITF Issue No. 94-3,Liability Recognition for Certain Employee Termination Benefits and Other Costs to Exit an Activity (including Certain Costs Incurred in a Restructuring). This Statement is effective for exit and disposal activities initiated after December 31, 2002. The adoption of this Statement did not have a material impact on the Company's consolidated financial statements.

In November 2002, the FASB issued FASB Interpretation No. 45,Guarantor's Accounting and Disclosure Requirements for Guarantees, Including Indirect Guarantees of Indebtedness of Others,an interpretation of FASB Statements Nos. 5, 57, and 107 and Rescission of FASB Interpretation No. 34 ("FIN 45"). FIN 45 clarifies the requirements of SFAS No. 5,Accounting for Contingencies, relating to the guarantor's accounting for, and disclosure of, the issuance of certain types of guarantees. FIN 45 requires that upon issuance of a guarantee, the guarantor must recognize a liability for the fair value of the obligation it assumes under that guarantee. FIN 45 covers guarantee contracts that have any of the following four characteristics: (a) contracts that contingently require the guarantor to make payments to the guaranteed party based on changes in an underlying that is related to an asset, a liability, or an equity security of the guaranteed party (e.g., financial and market value guarantees), F-16

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. Accounting Policies(Continued)

(b) contracts that contingently require the guarantor to make payments to the guaranteed party based on another entity's failure to perform under an obligating agreement (performance guarantees), (c) indemnification agreements that contingently require the indemnifying party (guarantor) to make payments to the indemnified party (guaranteed party) based on changes in an underlying that is related to an asset, a liability, or an equity security of the indemnified party, such as an adverse judgment in a lawsuitMTI" or the imposition of additional taxes due to either"Company"), a changeNew York corporation, was incorporated in 1961. MTI operates in two segments, the tax law or an adverse interpretation of the tax law, and (d) indirect guarantees of the indebtedness of others. FIN 45 specifically excludes certain guarantee contracts from its scope. Additionally, certain guarantees are not subject to FIN 45's provisions for initial recognition and measurement but are subject to its disclosure requirements. The initial recognition and measurement provisions are effective for guarante es issued or modified after December 31, 2002. The adoption of this Statement did not have a material impact on the Company's consolidated financial statements.

In November 2002, the EITF issued EITF Issue No. 00-21,Accounting for Revenue Arrangements with Multiple Deliverables, effective for arrangements entered into after June 15, 2003. This Issue defines units of accounting for arrangements with multiple deliverables resulting in revenue being allocated over the units of accounting for revenue recognition purposes. The adoption of this Issue did not have a material impact on the Company's consolidated financial statements.

In January 2003, the FASB issued FASB Interpretation No. 46,Consolidation of Variable Interest Entities ("FIN 46"). FIN 46 requires a variable interest entity to be consolidated by a company if that companyNew Energy segment which is subject to a majority of the risk of loss from the variable interest entity's activities or entitled to receive a majority of the entity's residual returns or both. FIN 46 also requires disclosures about variable interest entities that a company is not required to consolidate but in which it has a significant variable interest. The consolidation requirements apply to variable interest entities at the end of the first reporting period that ends after March 15, 2004. Certain of the disclosure requirements apply in all financial statements initially issued after December 15, 2003, regardless of the date on which the variable interest entity was created. The adoption of this Statement is not expected to have a material impact on the Company's consolidated financial statements.

In April 2003, the FASB issued SFAS No. 149,Amendment of Statement 133 on Derivative Instruments and Hedging Activities, to provide clarification on the meaning of an underlying, the characteristics of a derivative that contains financing components and the meaning of an initial net investment that is smaller than would be required for other types of contracts that would be expected to have a similar response to changes in market factors. SFAS No. 149 will be applied prospectively and is effective for contracts entered into or modified after June 30, 2003. This Statement will be applicable to existing contracts and new

contracts entered into after June 30, 2003 if those contracts related to forward purchases or sales of when-issued securities or other securities that do not yet exist. The adoption of this Statement did not have a

material impact on the Company's consolidated financial statements.

In May 2003, the FASB issued SFAS No. 150,Accounting for Certain Financial Instrumentswith characteristics of both Liabilities and Equity, to establish standards for how an issuer classifies and measures

certain financial instruments with characteristics of both liabilities and equity. An issuer is required to classify a financial instrument that is within the Standard's scope as a liability (or an asset in some circumstances). The requirements of this Statement apply to freestanding financial instruments, including those that comprise more

than one option or forward contract. This Statement does not apply to features that are embedded in a financial instrument that is not a derivative in its entirety. This Statement is effective for financial instruments entered into or modified after May 31, 2003, and otherwise

effective at the beginning of the first interim period beginning after June 15, 2003. The adoption of this Statement did not have a material impact on the Company's consolidated financial statements.

Reclassification

Certain 2002, Transition Period and 2001 amounts have been reclassified to conform to the 2003 presentation.The reclassifications have no effect on total revenues, total expenses, net loss or stockholders' equity as previously reported.

3. Issuance of Stock by Subsidiary

conducted through MTI MicroFuel Cells Inc. ("MTI Micro") was, a majority-owned subsidiary, and the Test and Measurement Instrumentation segment, which is conducted through MTI Instruments, Inc. ("MTI Instruments"), a wholly owned subsidiary.

At its MTI Micro subsidiary, the Company is primarily focused on the development and commercialization of advanced cord-free rechargeable power pack technology for portable electronics. MTI Micro has developed a patented, proprietary direct methanol fuel cell ("DMFC") technology called Mobion^®, which generates electrical power using up to 100% methanol as fuel. MTI Micro's Mobion^® technology is intended to replace current Lithium-Ion and similar rechargeable battery systems currently used by original equipment manufacturers (OEMs) in many hand held electronic devices such as personal digital assistants ("PDAs"), Smartphones and other accessories. The Company formed MTI Micro as a subsidiary on March 26, 2001. The Company2001 and currently owns approximately 90% of the outstanding common stock of MTI Micro. The remaining 10% is owned by strategic partners, other investors, and MTI Micro employees and board members. In addition, directors and employees of MTI Micro also hold options to purchase shares of MTI Micro common stock representing approximately .45% of MTI Micro's outstanding common stock on a fully diluted basis as of December 31, 2003.2005. Such options are vested or will vest within the next four years.

F-18At its MTI Instruments subsidiary, the Company designs, manufactures, and sells high-performance test and measurement instruments and systems. MTI Instruments was incorporated as a subsidiary on March 8, 2000 and has three product groups: general dimensional gaging, semiconductor and aviation. These products consist of electronic, computerized gaging instruments for position, displacement and vibration applications for the design, manufacturing and test markets; semiconductor products for wafer characterization of semi-insulating and semi-conducting wafers for the semiconductor market; and engine balancing and vibration analysis systems for both military and commercial aircraft.

MTI also co-founded and retains a minority interest in Plug Power Inc. ("Plug Power") (Nasdaq: PLUG), a developer of clean, reliable, on-site energy products.

New Energy Segment

Trends in portable electronics are creating a growing need for longer-lasting portable power. Consumers want increased intelligence and functionality for their portable devices. They want more memory, color screens, and convergence of several devices into a multi-purpose one (i.e. cell phones that are also digital cameras and MP3 players). More and more devices are being connected to some kind of network and increasingly used by consumers who want them on and leave them on. All these trends require more energy than current technologies - like battery technologies - may be able to provide.

MTI Micro expects that its proprietary technology should provide the improved power necessary to operate present and future generations of portable electronics and their accessories. MTI Micro's Mobion^® technology should last longer because of its high energy density, and it may eliminate the need for a lengthy recharge because it can be instantly refueled (recharged) by inserting a new fuel refill of methanol or refueling with a canister.

Mobion^® Technology: MTI Micro's Mobion^® direct methanol fuel cells are electrochemical devices that convert high energy density fuel (methanol) directly into electricity. The heart of a Mobion^® fuel cell is a membrane between two catalyst layers. The micro fuel cell produces electrical current when the fuel is introduced to the anode catalyst layer. At the anode catalyst the fuel reacts to produce protons, electrons, and carbon dioxide. The membrane allows protons to pass through to the cathode catalyst layer. Electrons are forced to take an alternative path, and flow through current collectors providing power. At the cathode catalyst layer, the protons and electrons recombine and react with oxygen to form water.

Direct methanol fuel cells operate relatively silently, and at low temperatures and MTI Micro's Mobion^® technology is being designed to reduce parts count and the need for complex components. The Mobion^® technology platform can be customized to provide portable power for a number of applications depending on the power level, required run time and size requirements.

MTI Micro's Mobion^® technology uses methanol as fuel. Methanol - a simple alcohol commonly used in windshield wiper fluid -is biodegradable and because it is a liquid, it is easily stored and transported. In addition, methanol is inexpensive, readily available and in its natural state has high energy density (about 4800 Wh/L). Methanol is increasingly seen as a fuel of choice in the industry

1

for micro fuel cells and it is being adopted by many in the industry because of its high energy density, packaging advantages, environmental and safety considerations and low cost.

Research and Development: MTI Micro is developing two DMFC technology platforms - low power and high power. Our low power platform is a simplified DMFC technology platform intended to eliminate many of the pumps and valves found in traditional DMFC systems. Low power applications are optimal for portable electronic applications such as PDAs, digital cameras and camera accessories. The high power platform may serve applications such as video cameras, laptops and power accessories for consumer and industrial electronics applications. There is also demand for improved power sources coming from both military and homeland securities markets for applications like unattended ground sensors and homeland security monitoring where the platform may be adapted with a few changes. MTI Micro's technology platform also focuses on using components and subsystems that use standard mass manufacturing practices. This technology platform is designed to permit MTI Micro to address the needs of applications with various power, duration and size requirements. DMFC development efforts are also focused on reliability, manufacturability, miniaturization and cost considerations, as well as compliance with codes and standards for DMFC systems. MTI Micro shipped its initial low volume Mobion^® fuel cell systems in late 2004. The Company and MTI Micro recognize that significant technical and engineering challenges remain before DMFCs can become commercially viable or available.

During 2005, 2004 and 2003, the Company spent approximately $9.7, $13.0 and $8.3 million, respectively, on product development and research costs, including $3.6, $4.0 and, $3.8 million, respectively, on partially funded research and development.

Product Development and Manufacturing: The product specifications required to successfully penetrate MTI Micro's targeted markets vary depending on the device being powered. Weight, volume, peak power, environmental conditions, power duration and reliability are all factors that pose limiting thresholds on Mobion^®fuel cell product introduction and acceptance. Therefore, MTI Micro will target products that have specifications that intersect its technology roadmap at various stages of development, thereby permitting the introduction of products earlier, while building its supply chain, manufacturing capabilities and key Original Equipment Manufacturers ("OEMs") relationships.

The Company believes that when commercialized, Mobion^® could eventually have higher energy density and therefore provide multiple times the benefits of existing Lithium-Ion batteries. When sold into the mass-commercial markets, Mobion^®fuel cells should be able to power a wireless electronic device for longer periods of time than Lithium Ion batteries without recharging/refueling, and be instantly refueled without the need for a power outlet or a lengthy recharge.

MTI Micro has built a number of system prototypes that demonstrate technology capabilities, operation in any orientation and operation at a range of voltages. MTI Micro also uses laboratory systems to demonstrate and test advanced concepts and technology. MTI Micro has demonstrated laboratory systems operating on 100% methanol and another laboratory system has achieved an energy density of 250 Watt hours per liter ("Wh/l"), which is comparable to that of a typical prismatic Lithium Ion battery. This lab system also achieved an energy density of 200 Watt hours per kilogram ("Wh/kg") on a weight basis. In addition, in lab systems MTI Micro extracted 1 Wh/cc from methanol and 1.25 Watt hours per gram ("Wh/g") on a weight basis. In addition, in 2005 MTI Micro demonstrated in the laboratory, a low power test unit that ran continuously on one integrated fuel tank to achieve greater than 380 Wh of energy in the same size and shape as the BA5590 battery - one of the most used ba tteries in the military.

MTI Micro currently plans to use contract manufacturers to manufacture its Mobion^®fuel cell products and has established contracts and relationships with key suppliers and contract manufacturers. MTI Micro also works with third-party suppliers to design, develop and manufacture subsystems and components of its Mobion^®fuel cell products.

The commercialization of MTI Micro's Mobion^® fuel cell products depends upon MTI Micro's ability to significantly reduce the costs of these systems and products, since they are currently substantially more expensive than systems and products based on existing technologies, such as rechargeable batteries. In addition to cost, MTI Micro continues to work on improving reliability, energy density, power density, life, and the overall performance of its Mobion^® systems as well as reducing its size - critical components for successful penetration into the marketplace. We cannot assure that MTI Micro will be able to sufficiently reduce the cost of these systems and products without reducing their performance, reliability and longevity.

Although it is difficult to predict the development timetable and challenges of our Mobion^®technology - a disruptive technology that may be able to provide multiple times the benefits of existing technologies, the Company expects to have units available for testing in the military markets by the end of 2006.

Business Strategy and Commercialization: The market for rechargeable batteries or power packs is large, well established and growing, experiencing sales of several hundred million units per year. MTI Micro's business strategy is to develop a robust, reliable, manufacturable, cost-effective Mobion^® technology platforms suitable for the consumer markets and to first target military

2

and industrial markets. Potential military markets include extended life power sources for a number of applications including communication devices, sensors, soldier on-body power and other mission critical devices for the war on terror. Potential industrial markets include portable communications devices, wireless scanners, hand-held inventory control devices and electronic healthcare products. The potential consumer markets span a broad range of mass-market portable electronic devices such as PDAs, cell phones, global positioning systems and digital cameras. Initial applications in the consumer markets will be high value-added devices such as portable navigation systems, digital cameras, game players, camcorders and accessories for them. The Company then plans to penetrate into the even larger market for products such as cell phones and laptops.

As a result of discussions with its partners, government agencies, OEMs and others, MTI Micro has developed a commercialization strategy that consists of two overlapping phases (military/industrial and consumer) for market introduction of its Mobion^®fuel cells. This tiered approach is intended to enable MTI Micro to gradually penetrate each of its selected markets.

To move the Company forward in 2006, the Company has set the following milestones for MTI Micro:

1. Increase system efficiency by 30 percent to 1.3 Wh per cc of fuel in the second quarter;
2. Customer demonstration of a product-intent military portable power system in the third quarter;
3. Develop a prototype for the consumer market that exceeds the energy density of Lithium Ion batteries in the third quarter;
4. Operationally robust units available to sell for field testing in the military market by the end of 2006;
5. Enter into an agreement with a lead consumer OEM by the end of 2006 - a year later than originally projected.

MECHANICAL TECHNOLOGY INCORPORATED AND SUBSIDIARIESDuring 2005, MTI Micro's management met important milestones, including:

1. The development of an engineering prototype with a replaceable fuel refill for the consumer market in the second quarter;

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

3. IssuanceDelivery of Stock by Subsidiary(Continued)five sensor power pack prototypes in the third quarter;
4. Delivery of a soldier/radio power pack prototype in the third quarter;
5. Doubled the energy density of the military's BA5590 battery in a laboratory unit during the fourth quarter;
6. Entered into an agreement with a lead customer/partner for the development of a military product during the fourth quarter.

Strategic Partnerships: MTI Micro intends to sell to multiple industries and enable OEMs to enhance existing product offerings. MTI Micro's strategy is to team with appropriate players in each of its targeted markets. In parallel with its product introduction strategy, MTI Micro plans to leverage joint development activities and other formal partnerships with key component and subsystems suppliers. MTI Micro also intends to rely heavily on OEMs as distribution channels for early military and industrial product introductions. MTI Micro anticipates that the nature of these relationships will vary, and as MTI Micro continues to mature and move forward with its product commercialization, such relationships will become increasingly important.

Strategic Agreements: The Gillette Company("Gillette"):On September 19, 2003, MTI Micro entered into a strategic alliance agreement with Gillette whereby MTI Micro, Gillette and Gillette's Duracell business unit agreed to jointly develop and commercialize complementary micro fuel cell products to power future mass market, high volume and portable consumer devices.

The agreement provides for a multi-year exclusive partnership for the design, development and commercialization of a low power direct methanol micro fuel cell power system and a compatible fuel refill system. The strategic alliance agreement has three main components. First, Gillette and MTI Micro shall work together from a technical and marketing perspective to help create a market for micro fuel cells. Second, for a period of time, MTI Micro will receive a percentage of net revenues related to Gillette's sale of fuel refills for micro fuel cells. Third, Gillette has made, and may make in the future equity investments in MTI Micro. On September 19, 2003, Gillette made an initial $1 million investment in MTI Micro common stock and may make additional investments of up to $4 million subject to agreed milestones related to technical and marketing progress. As part of the agreement, MTI agreed to provide enough funding to MTI Micro to co ver all operational costs for the first two years of the agreement and MTI satisfied this obligation in April 2004.

MTI Micro has not yet achieved the milestone necessary for the investment of the next $1 million in additional funds by Gillette. We do not expect this to occur, if at all, until late 2006 or 2007. Based on the current rate of progress with Gillette, we anticipate that Gillette will not invest the remaining $3 million until the end of 2008, if at all.

As part of the strategic alliance, MTI Micro transferred patents and other intellectual property related to fuel refill systems to Gillette, and Gillette transferred patents and other intellectual property related to DMFCs for hand held devices to MTI Micro. The patents and other intellectual property transferred to Gillette and any other intellectual property related to fuel refill systems for fuel cells for handheld devices, will be held in a licensing pool, which either party may license upon payment of a royalty fee. Both MTI Micro and Gillette will share in royalties related to the license of any intellectual property from the licensing pool.

The strategic alliance agreement is terminable by either party for cause at any time. In addition, either party may terminate the agreement without cause after the completion of tasks and acceptance of all deliverables relating to the OEM marketing calls and concept product development milestone and the engineering product design milestone, as defined in the agreement and the work plan, as amended.

On August 18, 2004, MTI Micro entered into an amendment to the multi-year strategic alliance agreement. The amendment clarified the nature of the deliverables for the third and fourth milestones in the work plan; added an additional milestone; and changed the due dates for the third and fourth milestones. MTI Micro also granted a non-exclusive license to Gillette to any improvements made by MTI Micro to intellectual property developed by Gillette.

In May 2005, MTI Micro worked collaboratively with Gillette and completed milestone No. 3- the development of an engineering prototype with a replaceable fuel refill.

On June 20, 2005, MTI Micro entered into the second amendment to the multi-year strategic alliance agreement. The amendment added an additional milestone relating to product identification, suitability and OEM validation. The amendment also added an additional termination right, exercisable by either party, relating to such milestone.

E.I. du Pont de Nemours and Company ("DuPont") : MTI Micro entered into an agreement with DuPont in August 2001 for the development and commercialization of DMFCs for portable electronics. This agreement expired in July of 2004 and was subsequently extended effective July 23, 2004 for an additional two years and may be renewed annually thereafter. The parties agreed to work together to jointly optimize DuPont's Nafion^®membrane technology for MTI Mobion^® fuel cell systems.

MTI Micro is also party to a supply agreement with DuPont providing that MTI Micro must purchase a majority of any membrane it purchases for its fuel cell from DuPont for a period of five years, commencing with the first commercial sale of fuel cells in volume by MTI Micro, if DuPont can meet best price and best quality in the industry. DuPont owns a minority equity interest in MTI Micro.

Flextronics International USA, Inc. ("Flextronics"): In November 2004, MTI Micro entered into a Design Services Agreement with Flextronics for design and development, pre-production design manufacturing engineering, prototyping and first article manufacturing of MTI Micro's Mobion^®fuel cell systems.

Military Contractor:In December 2005, MTI Micro signed an Early Adopter Alliance Agreement with a leading provider of intelligence, secure communications systems, government services and homeland security. As part of this agreement, the parties will work together to determine and evaluate the use and integration of MTI Micro's Mobion^® technology into the contractor's unattended ground sensor products. The two companies will cooperate on the demonstration of unattended ground sensor prototypes, identify military qualifications processes for any resulting products, and develop a market entry strategy for those products.

SES Americom Inc. ("SES Americom"):In December 2005, MTI Micro signed a Market Development Agreement with SES Americom, a world leader in satellite services and satellite-centric networks. As part of the agreement, the parties will determine and evaluate the use and integration of MTI Micro's Mobion^® technology into SES Americom products that may benefit from alternative energy sources such as fuel cells. The two companies will work jointly on market identification, the development and delivery of prototypes, qualification processes for any resulting products and the development of a market entry strategy for those products.

Recent Grants , Contracts and Developments:During 2005, Saft America Inc. ("Saft"), received a $1million contract from the US Army Communications Electronic Command ("CECOM") to develop an advanced solider power system ("HASP") for military applications. MTI Micro is a subcontractor under this agreement and has received a purchase order for $470,000. As part of the contract, both Saft and MTI Micro are working together to build, test and demonstrate a system that combines the benefits of both direct methanol fuel cells and Lithium Ion battery technology. This contract is ongoing.

In January 2006, MTI Micro was notified by the U.S. Department of Energy ("DOE") that due to a reduction in funding levels to the Hydrogen, Fuel Cells & Infrastructure Technologies Program, MTI Micro will not receive its proportion of funding in 2006 for the $6.14 million, three-year, cost-shared development contract awarded to MTI Micro on August 1, 2004. Under this contract with MTI Micro, DOE authorized $2.35 million of spending on a cost-shared basis which ultimately will result in $1.17 million of contract revenue.  Since the U.S. Congress has not appropriated funding for FY2007, we cannot determine at this time if funding for FY2007 will be committed to this contract.

During 2004, the New York State Energy and Research Development Authority ("NYSERDA") modified its original contract dated March 2002 twice to reflect the addition of Phase III for $348 thousand (Enhanced Energy Conversion Efficiency of Direct Methanol Fuel Cells - Validation and Testing) and Phase IV for $202 thousand (DMFCs for traffic sensors). The project supports DMFC technology development and commercialization efforts. This contract is ongoing.

In October 2004, MTI Micro received two contracts to demonstrate energy density advantages and to quantify potential logistical advantages of its Mobion^®fuel cells for the U.S. Armed Forces.

• The first award was administered by the U.S. Army Research, Development and Engineering Command and totaled approximately $250 thousand. The program included the delivery of five integrated, hybrid DMFC systems to Special Operations Forces ("SOF"). These systems are targeted to provide continuous power to devices used by SOF and to deliver more than two times the energy of the battery currently used while fitting the same form factor. On September 29^th, 2005 MTI Micro fulfilled the contract and delivered five prototypes for sensor applications to the U.S. Special Operations Command ("SOCOM") to evaluate new technologies for field readiness.
• The second award, a Phase I Small Business Innovative Research contract from U.S. Marine Corps System Command, provided $70 thousand during 2005 to analyze and report on current regulations and requirements necessary to field DMFCs and fuel refill systems. This contract was completed in 2005.

In April 2004, MTI Micro entered into a $200 thousand contract with Cabot Superior Micro Powders ("CSMP") to evaluate the performance of CSMP's membrane electrode assembly ("MEA") for portable fuel cell application. During 2005, this contract was amended to increase the contract amount to $210 thousand. This contract was completed in 2005.

In November 2003, the Company entered into a $250 thousand contract with the Harris Corporation ("Harris") to build two prototype units of a DMFC hybrid power supply in a similar form factor of a military battery. The original agreement entered into in October 2003 for $200 thousand was modified in May 2004 increasing the contract to $250 thousand, and was again modified in 2005 to decrease the contract to $150 thousand. This contract was completed during 2005.

Marketing and Sales:In the New Energy segment, MTI Micro has an experienced sales and marketing organization. Pursuant to the Gillette strategic alliance agreement, Gillette and the Company have commenced a joint marketing effort to gather market information, generate and refine product roadmaps, establish key relationships, gather customer and OEM feedback and launch products into the marketplace.  MTI Micro regularly evaluates its target market by conducting primary and secondary research and actively meeting and speaking with key industry suppliers and OEMs. In addition, MTI Micro representatives attend and speak at numerous conferences and trade shows for fuel cells, fuel cell development, batteries and other relevant target markets.

MTI Micro's Mobion^® technology was recognized with four industry awards since 2004. MTI Micro received the Frost & Sullivan 2005 Fuel Cell Entrepreneurial Company of the Year award and the 2004 Technology Innovation Award, and also accepted an award from Scientific American in recognition for its business leadership. A fourth award came in 2004 from Popular Science's Best of What's New as grand winner in the general innovations category.

Competition:We anticipate that the primary competitive considerations in MTI Micro's markets will be compatibility of DMFC power sources with portable electronic devices, requirements for power pack size, energy content, reliability and price. We also believe the first company to successfully introduce a DMFC product in the commercial markets will have significant advantages over its competitors. Many of MTI Micro's competitors have much greater access to capital, resources, component supplies, manufacturing capacity and distribution channels than MTI Micro. As such, because of the nature of product development, we cannot accurately determine our competitors' progress in developing DMFCs and whether such competitors' development efforts exceed MTI Micro's development efforts to date.

We analyze MTI Micro's competition based, in part, on two separate components of the DFMC market: (1) companies developing and providing DMFCs producing greater than three watts of energy, particularly companies focused on providing power devices for lap top computers; and (2) companies developing DMFCs producing less than three watts of energy. Within both of these categories, we have witnessed substantial changes during the last five years. Significant new competitors have emerged in Asia, Europe and in the United States. In addition, companies based in Japan, Korea, Germany and the United States have made patent filings in the United States for DMFC technologies.

Our primary focus in consumer markets is for hand held (less than 3 watt energy range) devices. Based on certain publicly available information, we believe MTI Micro's major competitors in the less than three watt energy range are large Asian companies, such as,

5

Hitachi Ltd. ("Hitachi"), Fujitsu Limited ("Fujitsu"), Samsung Electronics Co., Ltd. ("Samsung"), and Toshiba. These competitors have extensive patent portfolios and according to published reports, dedicated operations working on DMFCs and have publicly introduced prototypes. Hitachi demonstrated DMFCs in PDAs, Toshiba demonstrated DMFCs in Bluetooth headsets and in MP3 players, and Samsung has demonstrated an MP3 player. In addition, Samsung has publicly stated consumer market entry dates. We also compete with a number of smaller companies, such as, Medis Technologies Ltd., which announced a distribution and prototyping agreement with General Dynamics for military customers and a contract with Celestica in Ireland for the production of its power packs starting as early as the first quarter of 2007.

Based on certain publicly available information, we believe MTI Micro also faces significant competition in the greater than three watt energy range, and in particular from companies focused on providing power for lap top computers. In this segment, we believe our major competitors are large Japanese, Chinese, Korean and American companies, including but not limited to Canon Inc., Casio Computer Company Ltd., Nanfu Battery, Fujitsu Laboratories, UltraCell, Hitachi, Matsushita Electric Works (Panasonic), NEC, Samsung, Sanyo, and Toshiba. Each of these companies has greater access to resources than we do and, as the result of vertical integration, may have significant advantages in bringing product to market. We also consider Smart Fuel Cells AG ("Smart Fuel Cells"), based in Germany to be a significant competitor. Smart Fuel Cells has had product available in the market for three years. Other competitors include Protonex, a developer of fuel cell systems based on hydrogen PEM (proton exchan ge membrane) technology, and Millennium Cell, a developer of hydrogen battery technology for portable devices.

Intellectual Property and Proprietary Rights:MTI Micro relies on a combination of patent (both national and international), trade secret, trademark and copyright protection to protect its intellectual property ("IP"). MTI Micro's strategy is to apply for patent protection for all necessary design requirements. Additionally, MTI Micro systematically analyzes the existing IP landscape for DMFCs to determine where the greatest opportunities for developing IP exist.

In addition, MTI Micro enters into standard confidentiality agreements with its employees and consultants and seeks to control access to and distribution of its proprietary information. Even with these precautions, it may be possible for a third party to copy or otherwise obtain and use our products or technology without authorization or to develop similar technology independently. In addition, effective patent/copyright, and trade secret protection may be unavailable or limited in certain foreign countries.

As of December 31, 2005, MTI Micro has filed 76 U.S. patent applications, 21 of which have been awarded. Internationally, MTI Micro has filed 20 Patent Cooperation Treaty Applications, and 10 National Phase Patent Applications. MTI Micro has developed an extensive portfolio of patent applications in areas including fuel cell systems, components, controls, manufacturing processes and system packaging.

MTI Micro believes that the following patents are material to its business and that all of its patents may be significant to its future business activities.

In December 2000, MTI Micro licensed, on a non-exclusive basis, ten patent applications (eight issued and two abandoned) from Los Alamos National Laboratory ("LANL"). MTI Micro based its early DMFC systems work on these patents. MTI Micro has also licensed from LANL, on an exclusive basis, rights to European and Japanese counterpart applications for one LANL patent. In January 2005, MTI Micro and LANL modified the existing license such that it included in its entirety a total of nine issued U.S.

6

patents. No changes were made to the license fees or royalties due under such license. MTI Micro also has licensing rights and obligations with respect to IP developed under agreements with Gillette, DuPont and other vendors.

Codes and Standards: MTI Micro is a leader in the development of codes and standards associated with direct methanol fuel cells. In 2004, MTI Micro became the world's first company to obtain micro fuel cell safety compliance certifications for a fuel cell product from Underwriter's Laboratory ("UL") and from CSA International ("CSA"). MTI Micro received United Nations ("UN") packaging certification and was deemed compliant by the U.S. Department of Transportation for worldwide cargo shipment of its methanol fuel cartridges. The methanol cartridges were manufactured by MTI Micro's manufacturing partner Flextronics, in San Jose, California.

In addition to being the first company to receive UL and CSA certification, MTI Micro worked to help develop the proposal adopted by the UN which gives methanol fuel cartridges their own classification, a significant step forward for us and the industry. MTI Micro and others worked with regulatory bodies to create a first draft of the international standards for methanol safety and use, including those related to transport on commercial airplanes. At the same time, a number of presentations were made to various UN bodies in an effort to increase the understanding and acceptance of micro fuel cells and fuel cartridges. As a result, during 2005 the International Civil Aviation Organization's ("ICAO") safety panel recommended approval of the transportation and use of methanol fuel cells to power portable electronics in airplane passenger cabins. The action of this panel still needs to be submitted for comment to all ICAO members and then considered for final adoption by the 36-member ICAO Counc il, which could happen as early as the second quarter of 2006. If formally adopted, the regulation will go into effect on January 1, 2007. This is a key event in an on-going effort to develop regulatory acceptance of fuel cell power systems.

As part of the vote from ICAO's safety panel in 2005, butane and formic acid fuels were also approved but other fuels - such as hydrogen and sodium borohydride - were not approved outlining a possible barrier of entry into the business/leisure travel consumer market for those companies developing technologies with such fuels.

Marketing and Sales:In the Test and Measurement Instrumentation segment, MTI Instruments markets its products and services using channels of distribution specific to each of its product groups and customer base. The general dimensional gaging product group markets it products through a combination of manufacturer representatives in the United States and distributors overseas. The semiconductor product group markets its products exclusively through domestic distributors and international sales representatives, while the aviation group primarily sells direct to the end user.

To supplement these efforts, the company utilizes both commercial and industrial search engines, targeted newsletters, an independent representative network and appropriate trade shows to identify and expand its customer base.

Comparisons of sales by class of products, which account for over 10 percent of the Company's consolidated sales, are shown below for the years ended December 31:

Product Development and Manufacturing:MTI Instruments is working on expanding its range of capacitance products to increase penetration into new market segments and management believes that the success of the enterprise depends to a large extent upon innovation, technological expertise and new product development.Initiatives are underway to bring new products to market during 2006. MTI Instruments also plans to continue the development of advanced PBS systems for use in the military and commercial markets.

MTI Instruments' latest product offerings include: In the general gaging area,for 2004, MTI Instruments introduced the MTI-2100 Fotonic™ Sensor - a "next generation" fiber-optic sensor for high-resolution, non-contact measurement of high frequency vibration and motion analysis. The amplifier replaced the MTI-2000 Fotonic Sensor. MTI Instruments also added the 1515 low-noise amplifier to its Accumeasure line. It is designed to meet the stringent requirements of brake rotor measurement applications in the automotive industry. In Semiconductors, for 2004, MTI Instruments introduced the Proforma™ 300SA - a semi-automated tool for measuring thickness, total thickness variation, bow, warp, stress and flatness of 300mm wafers. In aviation, for 2004, MTI Instruments introduced the PBS-3300 - a compact balancing and vibration diagnostics system for use in mobile test cells and distributed test stands. The PBS-3300 is currently being used to balance the AGT 1500 gas turbine engine in the U.S. Army's M1A1 tank.

MTI Instruments assembles and tests its products at its facilities located in Albany, New York. MTI Instruments believes that its existing assembly and test capacity is sufficient to meet its current needs and short term future requirements. Also, management believes that most of the raw materials used in our products are readily available from a variety of vendors.

Intellectual Property and Proprietary Rights: MTI Instruments relies on trade secret laws and patents to establish and protect the proprietary rights of its products. In addition, MTI Instruments enters into standard confidentiality agreements with its employees and consultants and seeks to control access to and distribution of its proprietary information. Even with these precautions, it may be possible for a third party to copy or otherwise obtain and use our products or technology without authorization or to develop similar technology independently. In addition, effective patent and trade secret protection may be unavailable or limited in certain foreign countries. MTI Instruments has one patent issued supporting its semiconductor product line.

Significant Customers: MTI Instruments' largest customers include the U.S. Air Force and companies in the computer, electronic, semiconductor, automotive, aerospace, aircraft and bioengineering fields. In the Test and Measurement Instrumentation Segment, in 2005, the U.S. Air Force accounted for $2.385 million or 39.7% of product revenues; in 2004, the U.S. Air Force accounted for $3.508 million or 46.6% of product revenues; in 2003, the U.S. Air Force accounted for $2.261 million or 40.8% of product revenues. A loss of the U.S. Air Force as a customer would have a material adverse effect on this segment.

Recent Contracts: In 2002, MTI Instruments was awarded a multi-year U.S. Air Force contract to service and retrofit existing PBS-4100 jet engine balancing systems with the latest diagnostic and balancing technology could potentially generate up to a total of $8.8 million in sales for the Company between the years 2002 and 2007. As of December 31, 2005, MTI Instruments had recorded $5.3 million in orders for approximately 59% of the five-year contract's total value.

9

Competition: MTI Instruments is subject to competition from several companies, many of which are larger than MTI Instruments and have greater financial resources. MTI Instruments' competitors include ADE Corporation, Sigma Tech Corporation, Corning Tropel Corporation, Chadwick-Helmuth, ACES Systems and Keyence Corporation. While MTI Instruments has a share of its respective specialized market segments, it does not consider its share to be dominant within its industry. The primary competitive considerations in MTI Instruments' markets are product quality and performance, price, timely delivery, and the ability to identify, pursue and bring new customers. MTI Instruments believes that its employees, product development skills, sales and marketing systems and reputation are competitive advantages.

Employees

The total number of employees of MTI and its subsidiaries was 125 as of December 31, 2005, as compared to 128 as of December 31, 2004. Fiscal 2005 employees include corporate operations and the Company's two subsidiaries, MTI Micro and MTI Instruments. Executives and staff were chosen for their acumen, ability and experience in areas critical to the execution of the Company's core business strategy.

Financing Arrangements

Private Placement:The Company entered into a financing transaction with Fletcher International, Ltd. ("Fletcher"), on January 29, 2004 and amended the terms of such transaction on May 4, 2004. To date, Fletcher has purchased 2,680,671 shares of our common stock pursuant to such financing transaction. In addition, Fletcher has the right to purchase an additional $20 million of MTI's common stock, on one or more occasions, at a price of $6.023 (adjusted from $6.34) per share at any time prior to December 31, 2006.

We have filed registration statements covering all of the shares purc hased by Fletcher to date and in the event of any additional purchases we are similarly obligated to file one or more registration statements covering the resale of such shares. In connection with the late effective date for the registration statement filed on January 6, 2005, the Company issued and registered 66,413 shares of common stock to Fletcher without any additional payment. At December 31, 2005, Fletcher owned 393,515 shares or 1.3% of the Company's common stock.

Gillette Company ("Gillette"):Gillette entered into a strategic alliance agreement with MTI Micro on September 19, 2003, whereby MTI Micro, Gillette

and Gillette's Duracell business unit will seek to jointly develop and commercialize micro fuel cell products to power high-volume, low-power, hand-held and mass market portable consumer devices. This agreement was amended on June 20, 2005 and August 18, 2004. Pursuant to the agreement, Gillette purchased 1,088,278 shares of MTI Micro common stock (362,760 post 2004 1-for-3 reverse split) at a price of $.92 ($2.76 post 2004 1-for-3 reverse split) per share for $1 million pursuant to an equity investmentmillion. In connection with this agreement, (the

"Investment Agreement"). In addition to the foregoing referenced $1 million investment in MTI Micro common stock, Gillette may make

additional investments of up to $4 million subject to agreed milestones.

Operations Sold or Discontinued

Ling Electronics, Inc. and Ling Electronics Limited (collectively, "Ling") were sold on October 21, 1999 to SatCon in exchange for 770,000 shares of SatCon common stock (which stock had a market value of approximately $6.7 million on the transaction date). At the time of the sale, Ling designed, manufactured, and marketed electro-dynamic vibration test systems, high-intensity-sound transducers, power conversion equipment and power amplifiers used to perform reliability testing and stress screening during product development and quality control.

The sale of the Company's Technology Division, the sole component of the Technology segment, to NYFM, Incorporated (a wholly-owned subsidiary of Foster-Miller, Inc., a Waltham, Massachusetts-based technology company) was completed on March 31, 1998.

Lease Termination:MTI Micro entered into a Lease Termination Agreement in connection with certain premises at 750 University Avenue, Suite 270, Los Gatos, CA with 750 University, LLC. The Lease Termination Agreement was fully executed on February 9, 2006 with a lease termination effective date of January 31, 2006. The Company has agreed to invest $20 millionaccrued $25 thousand in connection with this lease termination obligation.

Contracts: In January 2006, MTI Micro before September 19, 2005 if other sourceswas notified by the DOE that due to a reduction in funding levels to the Hydrogen, Fuel Cells & Infrastructure Technologies Program, MTI Micro will not receive its proportion of funding in 2006 for the $6.14 million, three-year, cost-shared development contract awarded to MTI Micro on August 1, 2004. Under this contract with MTI Micro, the DOE has only authorized $2.35 million of spending on a cost-shared basis which will ultimately result in $1.17 million of contract revenue.  Since the U.S. Congress has not appropriated funding for FY2007, the Company cannot determine at this time if funding for 2007 will be committed to this contract.

• the potential for early termination of our agreement with Gillette and its $20 million commitmentDuracell division;
• our inability, or Gillette's inability, to develop Mobion^® fuel cell systems or fuel refills on our planned schedule;

11

• market acceptance of Mobion^® fuel cell systems;
• risks related to our first Mobion^® fuel cell product delivered in MTI Micro common stock. TheDecember 2004, including reliability, run time, customer acceptance and safety;
• our dependence on OEMs integrating Mobion^®fuel cell systems into their devices;
• the need for current regulations to change to permit methanol to be carried onto airplanes for Mobion^®fuel cell systems to achieve mass market commercialization;
• Fletcher's decision whether to exercise its additional investment rights and the price at which Fletcher purchases shares;
• risks related to the flammable nature of methanol as a fuel source;
• our history of losses;
• intense competition in the DMFC and instrumentation businesses;
• risks related to protection and infringement of intellectual property;
• the historical volatility of our stock price;

Except as may be required by applicable law, we do not undertake or intend to update or revise our forward-looking statements, and we assume no obligation to update any forward-looking statements contained in, or incorporated by reference into, this Annual Report on Form 10-K as a result of new information or future events or developments. Thus, you should not assume that our silence over time means that actual events are bearing out as expressed or implied in such forward-looking statements.

Risk Factors

We may be unable to raise additional capital to complete our product development and commercialization plans and the failure to complete such development and commercialization plans will materially adversely affect our business plans, prospects, results of operations and financial condition:Our cash requirements depend on numerous factors, including completion of our product development activities, our success in commercializing our Mobion^®fuel cell systems and market acceptance of Mobion^®fuel cells. Before we can successfully commercialize Mobion^®fuel cells, we must complete a number of critical activities, and certain events must occur, including further product development; manufacturing process development; development of large-scale production capabilities; completion, refinement and management of our supply chain; completion, refinement, and management of our distribution channel; and further work on codes and standards critical to consumer acceptance, including the existence of federal regulations that permit methanol in the passenger compartment of passenger airplanes. All of this will be expensive and require significant capital resources that are well in excess of all current resources available to us. We believe that we will need to raise additional funds to achieve commercialization of Mobion^® fuel cells. However, we do not know whether we will be able to secure additional funding, or funding on acceptable terms, to pursue our commercialization plans. We can raise funds in four ways: sale of certain of our Plug Power shares, sale of our Company's remaining investment guaranty is $8 million as of December 31, 2003.

In connection with the Gillette transaction, MTI Micro converted its Junior Convertible Preferred Class A and Senior Convertible Preferred Class B stock, into common stock and treasury stock of $15 thousand was retired.

On October 29, 2003, Jeong Kim, a member of the board of directorssale of MTI Micro purchased 1,088,278stock and sale of other assets. Pursuant to our amended agreement with Fletcher, they have the right to invest up to an additional $20 million in our common stock. However, there can be no assurances that Fletcher will exercise such right. If Fletcher does not exercise its additional investment rights we may be forced to increase the number of P lug Power shares sold to fund operations, or reduce spending on micro fuel cell development. If additional funds are raised through the issuance of equity securities, the percentage ownership of our then current shareholders will be reduced. If adequate funds are not available to satisfy either short or long-term capital requirements, we may be required to limit operations in a manner inconsistent with our development and commercialization plans, which would materially adversely affect our business plans, prospects, results of operations and financial condition in future periods.

We are dependent on continued government funding for new energy research and development and MTI Instruments product sales. The loss of such contracts and the inability to obtain additional contracts may have a material adverse effect on our business plans, prospects, results of operations, cash flows and financial condition:A large portion of revenues at MTI Instruments and MTI Micro for the next several years may come from government contracts. We can offer no assurance that we will be able to secure continued government funding. The loss of such contracts and the inability to obtain additional contracts could materially adversely affect our business plans, prospects, results of operations, cash flows and financial condition.

We may not successfully develop our new technology and the failure to do so will materially adversely affect our business plans, prospects, results of operations and financial condition:DMFCs are a new technology with many technical and engineering challenges still to be resolved. We cannot assure that we will be able to successfully resolve the technical and engineering challenges

12

of DMFCs, or if we are successful, that such solutions will be commercially viable. Resolution of these technical and engineering issues requires substantial resources including financial, managerial and technical resources. We cannot assure that all the necessary resources will be available to the degree, and at the times, they are needed. If we are unable to successfully develop Mobion^®fuel cells, our business plans, prospects, results of operations and financial condition would be materially adversely affected.

Current commitments for joint development, distribution, marketing and investment by The Gillette Company (Gillette) and its Duracell division may be subject to early termination and any such early termination will have material adverse consequences on MTI Micro's and the Company's business plans, prospects, results of operations and financial condition:Gillette and its Duracell division's commitments in the strategic alliance agreement and the other agreements entered into as a part of the strategic alliance transaction (including those commitments relating to joint development, distribution, marketing and investment) with MTI Micro are subject to early termination. Either MTI Micro or Gillette may terminate the strategic alliance agreement for cause at any time and at certain pre-defined periods of time, if technical milestones are not completed to the satisfaction of the other party. Gillette may also terminate the strategic alliance agreement prior to mass market commercializa tion if it decides not to establish fuel refill manufacturing capability.

The investment agreement with Gillette may be terminated if the strategic alliance agreement is terminated. In addition, any future investment by Gillette is conditioned upon MTI Micro reaffirming that the representations and warranties in the investment agreement are true as of the date of such investment. These representations and warranties include statements concerning ownership of intellectual property, and affirmations that MTI Micro is not infringing on the intellectual property of others and others are not infringing on MTI Micro's intellectual property. At this time we cannot determine whether MTI Micro will be able to make these statements as of the date of any potential future investments by Gillette, and the inability to make such statements could result in Gillette terminating the investment agreement.

Termination of MTI Micro's agreements with Gillette and its Duracell division would have material adverse consequences on MTI Micro's and the Company's business plans, prospects, results of operations and financial condition.

MTI Micro common stockmay never complete the development of commercially acceptable Mobion^® fuel cell products and may not be able to achieve profitable commercialization of its products in the military/industrial and consumer market on the timetable it anticipates, or at all, and any such delay or failure would have material adverse consequences on MTI Micro's and the Company's business plans, prospects, results of operations and financial condition:We cannot guarantee that MTI Micro will be able to develop commercially viable Mobion^® fuel cell products in the military/industrial and consumer market on the timetable it anticipates, or at all. The commercialization of Mobion^® fuel cell products requires substantial technological advances to improve the efficiency, functionality, reliability, cost, performance and environmental operating latitude of these systems and products and to develop commercial volume manufacturing processes for these systems a nd products. We cannot guarantee that MTI Micro will be able to develop the technology necessary for commercialization of Mobion^® fuel cell products, or acquire or license the required technology from third parties. MTI Micro's failure to develop the technology necessary for high-volume commercialization of Mobion^® fuel cells that are reliable, cost effective and present a value proposition to the customer will, in each case, have a material adverse effect on MTI Micro's and the Company's business plans, prospects, results of operations and financial condition.

A mass market for fuel cells may never develop or may take longer to develop than we anticipate.

Fuel cell systems represent emerging technologies, and we do not know whether consumers will adopt these technologies on a large scale or whether OEMs will incorporate these technologies into their products. In particular, if a mass market fails to develop, or develops more slowly than anticipated, for methanol portable power applications, we may be unable to recover our expenditures to develop our fuel systems and may be unable to achieve or maintain profitability, any of which could negatively impact our business. Estimates for the development of a mass market for fuel cell products and systems have lengthened in recent years. Many factors that are beyond our control may have a negative effect on the development of a mass market for fuel cells and our fuel systems for methanol applications. These factors include the following:

• cost competitiveness and physical size of fuel cell systems and components;
• availability, future costs and safety of methanol, natural gas and other potential fuel cell fuels;
• consumer acceptance of methanol or alternative fuel products;
• government funding and support for the development of methanol fuel cells for portable applications;
• the willingness of OEMs to replace current technology;
• consumer perceptions of methanol systems;
• regulatory requirements; and
• emergence of newer, breakthrough power technologies and products.

Our cost to produce our current Mobion^®fuel cell product exceeds the amount for which we can currently sell such product. If we are unable to reduce the costs of our Mobion^®fuel cells, it will have a material adverse effect on MTI Micro's and the Company's

business plans, prospects, results of operations and financial condition:The commercialization of MTI Micro's Mobion^® fuel cell products depends upon MTI Micro's ability to significantly reduce the costs of these systems and products, since they are currently substantially more expensive than systems and products based on existing technologies, such as rechargeable batteries.

The price of $.92 per share for $1 million.

During 2002, MTI Micro purchased treasury shares from former employees withour fuel cell products is dependent largely on material and other manufacturing costs. We are unable to offer any assurance that either we or a total value of $15 thousand.

On March 26, 2001, MTI Micro sold approximately 200,000 shares of its Junior Convertible Preferred Class A stockcontract manufacturer will be able to founding employees of MTI Micro atreduce costs to a price of $.50 per sharelevel which raised cash proceeds of $117 thousand. In July 2001, MTI Micro sold approximately 1.3 million shares of its senior convertible preferred class B stock to E.I. du Pont de Nemours and Company ("Dupont"), in connection with the establishmentwill allow production of a strategic partnership, atcompetitive product that the consumer finds attractive or that any product produced using lower cost materials and manufacturing processes will not suffer from a price of $1.18 per share which resultedreduction in cash proceeds of $750 thousandperformance, reliability and $750 thousand of prepaid materials.

On November 1, 2001, MTI Micro sold approximately 100,000 shares of its senior convertible preferred Class B stock to Dupont, at a price of $2.325 per share which raised proceeds of approximately $295 thousand.

Preferred shares were convertible into common shares on a one-for-one basis and there were no dividend rights.longevity.

The increase (decrease) inproduction costs of our initial industrial product were higher than its sales price. We recognize that successfully implementing our strategy and obtaining a significant share of the military, industrial and consumer markets requires that we offer our direct methanol fuel cell products at competitive prices, which can only be accomplished when production costs are cut substantially from current levels. If we are unable to produce direct methanol fuel cell products at competitive prices relative to alternative technologies and products, our target market customers will be unlikely to buy our fuel cell products.

The failure to achieve cost reductions may materially adversely affect MTI Micro's and the Company's paid-in-capitalbusiness plans, prospects, results of $881, $(28), $46operations and $1,163 thousand in 2003, 2002,financial condition.

Gillette may not be able to achieve commercialization of fuel refills on the Transition Periodtimetable we anticipate, or at all, and 2001, respectively, represents the changes indelay or failure to achieve such commercialization would have material adverse consequences on MTI Micro's and the Company's equity investmentbusiness plans, prospects, results of operations and financial condition:We cannot guarantee that Gillette will be able to, or will choose to, develop, acquire or license commercially viable fuel refills for Mobion^® fuel cell products on the timetable we anticipate, or at all. The commercialization of fuel refills for Mobion^® fuel cell products requires substantial technological advances to improve the efficiency, functionality, reliability, cost and performance of these systems and products and to develop commercial volume manufacturing processes for these systems and products. Gillette's failure to supply fuel refills would have a material adverse effect on MTI Micro's and the Company's business plans, prospects, results of operations and financial condition.

A viable market for micro fuel cell systems may never develop or may take longer to develop than we anticipate. If a market for fuel cells does not develop or is delayed, it will have a material adverse effect on our business plans, prospects, results of operations and financial condition:Micro fuel cell systems for portable electronic devices represent an emerging market, and we do not know the extent to which our targeted distributors and resellers will want to purchase them and whether end-users will want to use them. The development of a viable market for our systems may be impacted by many factors that are out of our control, including:

• the cost competitiveness of other micro fuel cell systems;
• the future costs of materials used to build our systems;
• consumer reluctance to try a new product;
• consumer perceptions of our systems' safety;
• regulatory requirements;
• improvements in existing rechargeable battery technology; and
• the emergence of newer, more competitive technologies and products.

If a viable market fails to develop or develops more slowly than we anticipate, we may be unable to recover the losses we will have incurred to develop our product and we may be unable to achieve profitability, each of which would have a material adverse effect on our business plans, prospects, results of operations and financial condition.

Our first field test ready military application Mobion^®fuel cell product could fail due to technical, customer acceptance, safety or other reasons. Any such failure could have a material adverse effect on MTI Micro, which results from third-party stock transactions in MTI Micro.

8. Impairment Losses

The Company regularly reviews its securities available for sale and holdings to determine if any declines in value of those securities available for sale and holdings are other than temporary. The Company assesses whether declines in the value of its securities and holdings in publicly traded companies, measured by comparison of the current market price of the securities to the carrying value of the Company's securities and holdings, are considered to be other than temporary based on factors that include (1) the length of time carrying value exceeds fair market value, (2) the Company's assessment of the financial condition and the near term prospects of the companies, and (3) the Company's intent with respect to the securities and holdings.

F-23Alternatives to our technology could render our systems obsolete prior to commercialization, which would have a material adverse effect on our business plans, prospects, results of operations and financial condition:Our Mobion^® fuel cells are one of a number of alternative portable power energy solutions being developed as replacements for batteries, including thin film batteries, extended life lithium batteries and other types of fuel cell technologies. Technological advances in existing battery technologies or other fuel cell technologies may render our micro fuel cell systems obsolete and this would materially adversely affect our business plans, prospects, results of operations and financial condition.

TheMTI Micro is dependent upon external OEMs to purchase certain of its products and integrate Mobion^® fuel cells into their products. If external OEMs do not purchase and integrate Mobion^® fuel cells into their products, our market will be very limited, which could have a material adverse effect on MTI Micro's and the Company's effective income tax rate frombusiness plans, prospects, results of operations and financial condition: To be commercially useful, certain of our Mobion^®fuel cells must be integrated into products manufactured by OEMs. We cannot guarantee that OEMs will manufacture appropriate products or, if they do manufacture such products, that they will choose to use Mobion^®fuel cells. Any integration, design, manufacturing or marketing problems encountered by OEMs could adversely affect the market for Mobion^® fuel cells, which could have a material adverse effect on MTI Micro's and the Company's business plans, prospects, results of operations and financial condition.

In order to achieve mass commercialization of Mobion^® fuel cells, customers must be able to carry methanol fuel inside the passenger compartment of commercial airlines. If current airline, Federal Aviation Administration ("FAA") and certain international regulations do not change, passengers will be unable to carry non-dilute methanol in the passenger compartments of airplanes, which will have a material adverse effect on MTI Micro's and the Company's business plans, prospects, results of operations and financial condition: Current airline and FAA regulations and certain international laws, regulations and treaties limit the amount and concentration of methanol that any passenger can carry aboard passenger planes. We believe that these regulations must change for mass commercialization of Mobion^® fuel cell products to be possible. If pending regulatory changes are approved by ICAO, this will permit direct methanol micro fuel cells and refill cartridg es to be carried in the passenger compartment of airplanes. If these regulations do not change, it would materially adversely affect MTI Micro's ability to achieve mass commercialization of Mobion^® fuel cell products and have a material adverse effect on MTI Micro's and the Company's business plans, prospects, results of operations and financial condition.

In connection with the 2004 private placement, we may have to (1) sell shares of our common stock at prices which result in substantial dilution to our shareholders, and (2) issue additional shares of our common stock to Fletcher at prices that may be substantially below market value at the time of issuance without any payment required by Fletcher, which would cause our shareholders to suffer additional dilution: After giving effect to the 1,261,829 shares of common stock we issued to Fletcher on December 22, 2004 (as well as all shares issued or to be potentially issued to Fletcher in connection with our failure to satisfy the registration requirement as discussed in Note 11, Shareholders' Equity), the 2004 private placement provided Fletcher additional investment rights to purchase up to an additional $20 million of our common stock at a price equal to $6.34 per share (subject to adjustment). This price has been reduced to $6.023 per share due to our failure to satisfy the registratio n requirement, and may be further reduced due to, among other things, continuing operations, including equity in holdings' losses, differed from the Federal statutory rate:

The deferred tax assets and liabilities consistfailure to satisfy such registration requirement. Any exercise of the following tax effectsadditional investment rights could result in sales of our common stock at prices that are below the market price for our common stock at the time the investment right is exercised and could result in substantial dilution to our shareholders.

In any event, 8,330,411 shares is the maximum number of shares of our common stock we may be required to certain changesissue to Fletcher, which amount includes the 1,418,842 shares issued on January 29, 2004, the 1,261,829 shares issued on December 22, 2004 and the 66,413 registration penalty shares issued on April 20, 2005.

In connection with the 2004 private placement, we are responsible for having the resale of shares purchased by Fletcher registered with the SEC within defined time periods and subject to penalties if the shares are not registered with the SEC within those defined time periods: Pursuant to our agreement with Fletcher, we are obligated, within ten business days after the closing of the purchase of

any additional shares by Fletcher pursuant to rights issued in connection with the 2004 Private Placement, to file a registration statement with the SEC covering the resale of all such shares. We are also obligated to cause each of those registration statements to be declared effective not more than sixty (60) days after the closing of the purchase of such shares, or if the registration statement is reviewed by the SEC, not more than ninety (90) days after the closing of the purchase of such shares. If we fail to file the registration statements or become effective as set forth above, 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 we fail to satisfy our obligations and adjust the exercise price for the additional investment rights to such lower price. In addition, such failure may result in an extension of the investment term for ea ch day we fail to satisfy our registration obligations. The Company initially filed a Registration Statement on January 6, 2005 which was within ten business days after the closing of the purchase of additional shares by Fletcher on December 22, 2004. The 90-day deadline for this Registration Statement to be declared effective was March 22, 2005. Since the Registration Statement was declared effective on April 21, 2005, we failed to meet the March 22, 2005 deadline and therefore were required to issue 66,413 additional shares of common stock to Fletcher without any payment required on its part.

The sale of a substantial amount of our common stock in the public market could materially decrease the market price of our common stock: The Company agreed as part of the 2004 Private Placement with Fletcher to register for resale shares of our common stock owned by Fletcher. If Fletcher exercised its remaining investment right and a substantial amount of our common stock were sold in the public market, or even targeted for sale, it could have a material adverse effect on the market price of our common stock and our ability to sell common stock in the future.

Current shareholders may be diluted as a result of additional financings: If we raise additional funds through the sale of equity or convertible debt securities in either the Company or MTI Micro, current shareholders' percentage ownership will be reduced. In addition, these transactions may dilute the value of common stock outstanding. Moreover, we may have to issue securities that may have rights, preferences and equity transactions,privileges senior to our common stock. We cannot assure that we will be able to raise additional funds on terms acceptable to us, if at all. If future financing is not available or is not available on acceptable terms, we may not be able to fund our future needs, which occurredwould have a material adverse effect on our business plans, prospects, results of operations and financial condition.

We may be involved in 1997.intellectual property litigation that causes us to incur significant expenses or prevents us from selling our products, which could have a material adverse effect on MTI Micro's and the Company's business plans, prospects, results of operations and financial condition:In recent years, hundreds of fuel cell patents have been issued worldwide. Many of these patents are broadly written and encompass basic and fundamental theories of how fuel cells should or could work. As we continue to develop our technology, our designs may infringe the patent or intellectual property rights of others. Whether our technology infringes or not, MTI Micro and our Company may become subject to lawsuits in which it is alleged that we have infringed the intellectual property rights of others. We may also commence lawsuits against others who we believe are infringing upon MTI Micro's rights. Involvement in intellectual property litigation could result in significant expense to MTI Micro and our Com pany, adversely affecting the development of sales of the challenged product or intellectual property and diverting the efforts of our technical and management personnel, whether or not such litigation is resolved in our favor. In the event of an adverse outcome as a defendant or plaintiff in any such litigation, MTI Micro and the Company may, among other things, be required to:

• pay substantial damages;
• cease the development, manufacture, use, sale or importation of products that infringe upon other patented intellectual property;
• expend significant resources to develop or acquire non-infringing intellectual property;
• discontinue processes incorporating infringing technology; or
• obtain licenses to the infringing intellectual property.

We cannot guarantee that MTI Micro or the Company would be successful in such development or acquisition or that such license would be available upon reasonable terms. Any such development, acquisition or license could require the expenditure of substantial time and other resources and could have a material adverse effect on MTI Micro's and the Company'sbusiness plans, prospects, results of operations and financial condition.

MTI Micro's products use potentially dangerous, flammable fuels, which could subject its business and the Company to product liability claims. Any such lawsuits or claims could have a material adverse effect on MTI Micro's and the Company's business

plans, prospects, results of operations and financial condition: The sale of Mobion^® fuel cells exposes MTI Micro and the Company to potential product liability claims that are inherent in the methanol and products that use methanol industry. Methanol is flammable and therefore potentially dangerous. Any accidents involving MTI Micro's products or other methanol-based products could materially impede widespread market acceptance and demand for DMFCs which could have a material adverse effect on MTI Micro's and the Company's business plans and prospects. In addition, MTI Micro may be held responsible for damages beyond the scope of its insurance coverage. We also cannot predict whether MTI Micro will be able to maintain its insurance coverage on acceptable terms. Damages beyond the scope of MTI Micro's insurance coverage or the inability to maintain insurance coverage on acceptable terms would have a material adverse impact on MTI Micro's and the Company's business plans, prospect s, results of operations and financial condition.

We have incurred losses and anticipate continued losses. If we do not become profitable and sustain profitability, it will have a material adverse effect on our business plans, prospects, results of operations and financial condition: As of December 31, 2005, we had an accumulated deficit of $81.718 million. For the year ended December 31, 2003,2005, our net loss was $15.094 million, which includes a net gain of $10.125 million from sales of securities available for sale and a loss of $10.407 million from derivative valuations and an operating loss of $15.098 million. We expect to continue incurring net losses from operations until we can produce sufficient revenues to cover costs. In order to achieve profitability, we must successfully achieve all or some combination of the Company has approximately $459 thousandfollowing:

• develop new products for existing markets;
• sell these products to existing and new customers;
• increase gross margins through higher volumes and manufacturing efficiencies;
• control operating expenses; and
• develop and manage distribution capability.

Furthermore, we anticipate that we will continue to incur losses until we can produce and sell our fuel cell systems on a large-scale and cost-effective basis. Even if we do achieve profitability, we may be unable to sustain or increase our profitability in the future. Failure to do so will have a material adverse effect on our business plans, prospects, results of operations and financial condition.

Our competitors may develop a more cost effective, better product and bring that product to market faster than we can. If we do not create a competitive DMFC product or we are late to market, it will have a material adverse effect on our business plans, prospects, results of operations and financial condition: There are a number of other companies developing DMFCs. Some of our competitors may have better access to resources and capital than we do. Some of our competitors are much larger and have better access to manufacturing capacity, supply chains and distribution channels than we do. Some of our competitors may resolve technical or engineering issues before we do. Accordingly, one or more of our competitors may bring a mass commercial product to market before we do. In addition, one or more of our competitors may make a better or more cost effective product than we can make. Failure to get to market with the best and most cost competitive DMFC product before our competitors would have a material adverse effect on our business plans, prospects, results of operations and financial condition.

We have limited experience manufacturing fuel cell systems on a commercial basis. If we do not achieve the necessary manufacturing capabilities, it will have a material adverse effect on our business plans, prospects, results of operations and financial condition: To date, we have focused primarily on research and development tax credit carryforwards, which beginand have limited experience manufacturing micro fuel cell systems on a commercial basis. We plan to expiremanufacture our fuel cell products through third-party contract manufacturers. We can offer no assurance that either we, our contract manufacturers or any other party we partner with to volume-produce our products will develop efficient, automated, low-cost manufacturing capabilities and processes to meet the quality, price, engineering, design and production standards or production volumes required to successfully mass market our fuel cell products. Even if we or our contract manufacturers are successful in 2018,developing such manufacturing capability and approximately $150 thousandprocesses, we do not know whether we or they will be timely in meeting our product commercialization schedule or the production and delivery requirements of alternative minimum tax credit carryforwards, whichpotential customers. Failure to develop or procure such manufacturing capabilities will have no expiration date.

11. Stock Based Compensation (Continued)

The 1996 Stock Incentive Plan ("1996 Plan") was approved by shareholders during December 1996. The 1996 Plan provides that an initial aggregate number of 500,000 shares of common stock may be awarded or issued. The number of shares which may be awarded under the 1996 Plan may be increased by 10% of any increase in the number of outstanding shares of common stock for reasons other than shares issued under this 1996 Plan.

The number of shares which may be awarded under the 1996 Plan have been adjusted for stock splits and rights offerings, and during 2003, 2002, the Transition Period and 2001, the total number of shares which may be awarded under the 1996 Plan were 3,478,746 shares. Under the 1996 Plan, the Board of Directors is authorized to award stock options, stock appreciation rights, restricted stock, and other stock-based incentives to officers, employees and others.

Options are generally exercisable in from one to four cumulative annual amounts beginning 12 months after the date of grant. Certain options granted may be exercisable immediately or begin vesting immediately. Option exercise prices are not less than 85 percent of the market value of the Company's common stock on the date of grant. Unexercised options generally terminate ten years after date of grant. The Company has elected to follow APB Opinion No. 25,Accounting for Stock Issued to Employees, and related Interpretations, in accounting for employee stock-based compensation and to provide the disclosures required under SFAS No. 123,Accounting for Stock Based Compensation. APB Opinion No. 25 requires no recognition of compensation expense for most of the stock-based compensation arrangements provided by the Company, namely, broad-based employee stock purchase plans and option grants where the exercise price is equal to or not less than 85 percent of the market value at the date of grant. However, APB Opinion No. 25 requires recognition of compensation expense for variable award plans over the vesting periods of such plans, based upon the then-current market values of the underlying stock. In contrast, SFAS No. 123 requires recognition of compensation expense for grants of stock, stock options, and other equity instruments, over the vesting periods of such grants, based on the estimated grant-date fair values of those grants.

On December 22, 2003, the Company announced the successful completion of the first phase of its stock option exchange offer. A total of 757,000 options with an average exercise price of approximately $19 were tendered by employees and then cancelled by the Companyfund our product development efforts in exchange for their assistance or the contribution to us of intellectual property. Any such issuance of equity securities would reduce the percentage ownership of our then current shareholders, which would have a material adverse effect on our business plans, prospects, results of operations and financial condition.

We will rely on our partners to develop and provide components for our Mobion^® fuel cell systems. If our partners do not meet our quality, quantity, reliability or schedule requirements, it will have a material adverse effect on our business plans, prospects, results of operations and financial condition: We depend on third parties to supply many of the components of our Mobion^® fuel cell systems. A supplier's failure to develop and supply components in a timely manner, or to develop or supply components that meet our quality, quantity or cost requirements, or our inability to obtain substitute sources of these components on a timely basis or on terms acceptable to us, would harm our ability to manufacture our fuel cell systems. In addition, to the extent that our supply partners use technology or manufacturing processes that are proprietary, we may be unable to obtain comparable components fr om alternative sources. Failure to do so will have a material adverse effect on our business plan, prospects, results of operations and financial condition.

In addition, platinum is a key material in our micro fuel cells. Platinum is a scarce natural resource and we are depending upon a sufficient supply of this commodity. While we do not anticipate significant near or long-term shortages in the supply of platinum, any such shortages would adversely affect our ability to produce commercially viable fuel cell systems or significantly raise our cost of producing our fuel cell systems.

Our inability to deliver a commercially viable Mobion^®fuel cell on time, or at all, will have a material adverse effect on our business plans, prospects, results of operations and financial condition: We anticipate having field test ready military application Mobion^®fuel cell product available for sale by the end of 2006. There may be technical or engineering challenges we have not anticipated, issues of reliability for our device, an inability for our device to be integrated into existing electronic devices, difficulties in obtaining materials or components, or problems with manufacturing or distribution, and many other problems that we have not, and perhaps could not anticipate. All of these issues could delay or prohibit further releases of additional Mobion^®fuel cell products, which would have a material adverse effect on our business plans, prospects, results of operations and financial condition.

Failure to achieve future product development and the timing associated with entry into the military, industrial or consumer market or commercialization milestones will have a material adverse effect on our business plans, prospects, results of operations and financial condition: We have established aggressive product development and commercialization milestones and dates for achieving development goals related to technology and design improvements. We use these milestones to assess our progress toward developing commercially viable fuel cell systems. Delays in our product development will likely have a material impact on our commercialization schedule. If we experience delays in meeting our development goals or if our micro fuel cell systems exhibit technical defects or if we are unable to meet cost, performance or manufacturing goals, including power output, useful life and reliability, our commercialization schedule will be delayed. In this event, potential purchasers of our initial comme rcial systems may choose alternative technologies and any delays could allow potential competitors to gain market advantages. We cannot assure that we will successfully achieve our milestones in the future issuanceand the failure to achieve such milestones would have a material adverse effect on our business plans, prospects, results of options at a one-for-two ratio. New options will be issuedoperations and financial condition.

Our resources available to fund operations may fluctuate as the value of Plug Power's share price fluctuates. Such price fluctuations could result in the final phase of the exchange offer on or after June 23, 2004 at the then current market price to employees and directors who are employed by the Company or serve as directorsour requiring additional funding sooner than anticipated: A primary asset of the Company fromis the acceptance date through the date that the new options are granted. As of March 5, 2004, the Company anticipates issuing 341,000 options associated with the exchange.

During 2002, the Company awarded 50,000 restricted shares of common stock which vested over a one-year period. During 2000, the Company awarded 60,000 options to consultants. Certain of these shares under option vest over a four-year period. Presented below is a summary of

As of December 31, 2005, the Company owned by the Company. As a condition of the exchange, FAC agreed not to sell its remaining3,693,436 shares of the Company's common stock for two years. The Company recorded a gain on the exchange transaction of $8,006 thousand and recorded treasury stock at a cost of $13,606 thousand.

As a result of the transaction, effective December 20, 2002, the Company was no longer required to account for its remaining holdings in Plug Power, underwhich is a publicly traded company. The market price of the equity method of accounting. Under the equity method of accounting,Plug Power common stock may fluctuate due to market conditions and other conditions over which the Company was required to report its proportionate sharehas no control. Fluctuations in the market price of Plug Power's common stock may result in a reduction of resources available to fund operations which could result in our requiring additional funding sooner than anticipated.

If we are not successful in protecting our patents and intellectual property, it will have a material adverse effect on our business plans, prospects, results of operations and financial results.condition: Patent and trade secret rights are of material importance to us. No assurance can be given as to the issuance of patents or, if so issued, as to their scope. Patents granted may not provide meaningful protection from competitors. Even if a competitor's products were to infringe patents owned by us it would be costly to pursue an enforcement action and would divert funds and resources which otherwise could be used in operations. Furthermore, there can be no assurance that an enforcement action would be successful.

Our business plans, prospects, results of operations and financial condition could be harmed if we encounter difficulties in effectively managing the budgeting, forecasting and other process control issues presented by such a rapid change.

Our share price could be subject to extreme price fluctuations, and shareholders could have difficulty trading shares: The markets for high technology companies in particular have been volatile, and the market price of our common stock, which is traded on the Nasdaq National Market under the symbol MKTY, has been and may continue to be subject to significant fluctuations. Fluctuations could be in response to operating results, announcements of technological innovations or new products by us, or by our competitors, patent or proprietary rights developments, and market conditions for high technology stocks in general. In addition, the stock market in recent years has experienced extreme price and volume fluctuations that sometimes have been unrelated or disproportionate to the operating performance of individual companies. These market fluctuations, as well as general economic conditions, may adversely affect the market price of our common stock and the ability of shareholders to dispose of o ur common stock.

General economic conditions may affect investors' expectations regarding our financial performance and adversely affect our stock price, which may result in a material adverse effect on our business plans, prospects, results of operations and financial condition: Certain industries in which we sell and intend to sell products, such as the energy and semiconductor industries are highly cyclical. In the future, our results may be subject to substantial period-to-period fluctuations as a consequence of the industry patterns of our customers, general or regional economic conditions, and other factors. These factors may also have a material adverse effect on our business plans, prospects, results of operations and financial condition.

The Company maintainsloss of key employees may have a voluntary savingsmaterial adverse effect on our business plans, prospects, results of operations and retirement plan (Internal Revenue Code Section 401(k) Plan) covering substantially all employees.financial condition: Our success will depend, in large part, upon our ability to attract, motivate and retain highly qualified scientists and engineers, as well as highly skilled and experienced management, sales and technical personnel. Competition for these personnel is intense, and there can be no assurance that we will be successful in attracting, motivating or retaining key personnel. Our success depends to a significant extent upon a number of key employees, including members of senior management. The loss of the services of one or more of these senior executives or key employees, or the inability to continue to attract qualified personnel, could delay product development cycles or otherwise harm our business and could have a material adverse effect on our business plans, prospects, results of operations and financial condition.

Litigation

Lawrence

On September 9, 1998, Barbara Lawrence, the Lawrence Group, Inc. ("Lawrence"), and certain other Lawrence-related entities ("Plaintiffs") initially filed suit in the Bankruptcy Court and the United States District Court for the Northern District of New York which were subsequently consolidated in the District Court, against First Albany Corporation ("FAC"), Mechanical Technology,MTI, Dale Church, Edward Dohring, Beno Sternlicht, Alan Goldberg and George McNamee (former(Sternlicht, Goldberg and McNamee are former Directors of the Company), Marty Mastroianni (former President and Chief Operating Officer of the Company), and 33 other individuals ("Defendants") who purchased a total of 820,909 (2,462,727 shares post split) shares of the Company's stock from the Plaintiffs. The case concerns the Defendants' 1997 purchase of Mechanical TechnologyMTI shares from the Plaintiffs at the price of $2.25 per share ($0.75 per share post split). FAC acted as Placement Agent for the Defendants in the negotiation and sale of the sh aresth e shares and in proceedings before the Bankruptcy Court for the Northern District of New York, which approved the sale in September 1997.

Plaintiffs claim that the Defendants failed to disclose material inside information concerning Plug Power, LLC to the Plaintiffs and therefore the $2.25 per share ($0.75 per share post split) purchase price was unfair. Plaintiffs are seeking damages of $5 million plus punitive damages and costs. In April 1999, Defendants filed a motion to dismiss the amended complaint, which was denied by the Bankruptcy Court. On appeal in October 2000, Plaintiffs' cause of action was dismissed by the United States District Court for the Northern District of New York. In November 2000, Plaintiffs filed an appeal of that dismissal with the United States Court of Appeals for the Second Circuit. In June 2002, the Second Circuit Court of Appeals reversed the District Court decision and remanded the case for further consideration of the Plaintiff's claims as motions to modify the Bankruptcy Court sale order. The Plaintiff's claims have now been referred back to Bankruptcy Court for such consideration. In September 2003, th e Bankruptcy Court issued an order permitting Plaintiffs to conduct limited discovery concerning how First Albany formed an opinion about the Company's stock up until the date the Stock Purchase Agreement was executed. Discovery has commenced.

BelowThe following discussion should be read in conjunction with our accompanying Financial Statements and Notes thereto included within this Annual Report on Form 10-K. In addition to historical information, this Annual Report on Form 10-K and the following discussion contain statements that are not historical facts and are considered forward-looking within the meaning of the Private Securities Litigation Act of 1995. Certain statements made in this document that state Management's intentions, hopes, goals, beliefs, expectations, projections, plans, anticipation, outlook or predictions of the future are forward looking statements. Such statements include, among others, estimates of cash needs and sources; our ability to meet cash needs in the future; MTI Micro's plans under its strategic alliance agreement with its fuel refill partner; future prospects and applications for fuel cell systems; MTI's, MTI Micro's and MTI Instruments' future business prospects, technology and performance; the market po tential for and progress MTI Micro is making in developing its Mobion fuel cells; the significance of any contracts, grants, awards, or other recognition that MTI Micro may receive; the timing or success of market entry, in either the vertical or horizontal markets, by MTI Micro; MTI Micro's ability to meet its stated milestones on time, if at all; MTI, MTI Micro's and MTI Instruments' ability to increase or maintain sales into military and other governmental markets; the importance of any relationships we may have, and our ability to maintain those relationships going forward; MTI Micro's ability to produce products or prototypes consistent with any announced specifications or customer requirements, if at all; MTI Micro's ability to remain a reconciliationleader in advancing codes and standards; and the importance of changesany patents or codes and standards. All forward-looking statements are made as of today, and MTI disclaims any duty to update such statements. It is important to note that the Company's actual results could differ materially from those projected in forward-looking statements. Factors that could cause the anticipated results not to occur include, among others, risks related to financing; uncertainties in development, manufacturing, competition and consumer demand for DMFCs; Gillette's ability to terminate its agreements with MTI Micro prior to commercialization of DMFCs; and the risk factors listed in Item 1A: Risk Factors.

Overview

Mechanical Technology Incorporated, ("MTI" or the "Company"), a New York corporation, was incorporated in 1961. MTI operates in two segments, the New Energy segment which is conducted through MTI MicroFuel Cells Inc. ("MTI Micro"), a majority-owned subsidiary, and the Test and Measurement Instrumentation segment, which is conducted through MTI Instruments, Inc. ("MTI Instruments"), a wholly owned subsidiary.

At its MTI Micro subsidiary, the Company is primarily focused on the development and commercialization of advanced cord-free rechargeable power pack technology for portable electronics. MTI Micro has developed a patented, proprietary direct methanol fuel cell ("DMFC") technology called Mobion^®, which generates electrical power using up to 100% methanol as fuel. MTI Micro's Mobion^® technology is intended to replace current Lithium-Ion and similar rechargeable battery systems used by original equipment manufacturers (OEMs) in many hand held electronic devices such as PDAs, Smartphones and different accessories. The Company believes that when commercialized, Mobion^® could eventually have higher energy density and therefore provide multiple times the benefits of existing Lithium-Ion batteries. When and if Mobion^®fuel cells are ready to be sold in mass-commercial markets, they should be able to power a wireless electronic device for lon ger periods of time than Lithium Ion batteries without recharging/refueling, and be instantly refueled without the need for a power outlet or a lengthy recharge.(See Item 1: Business, New Energy Segment.)

At its MTI Instruments subsidiary, the Company designs, manufactures, and sells high-performance test and measurement instruments and systems. MTI Instruments was incorporated as a subsidiary on March 8, 2000 and operates three product warrantygroups: general dimensional gaging, semiconductor and aviation. These products consist of electronic, computerized gaging instruments for position, displacement and vibration applications within the design, manufacturing and test markets; semiconductor products for wafer characterization of semi-insulating and semi-conducting wafers within the semiconductor market; and engine balancing and vibration analysis systems for both military and commercial aircraft.(See Item 1: Business, Test and Measurement Instrumentation Segment)

MTI also co-founded and retains a minority interest in Plug Power Inc. ("Plug Power") (Nasdaq: PLUG), a developer of clean, reliable, on-site energy products.

Our cash requirements depend on numerous factors, including completion of our product development activities, ability to commercialize our systems, market acceptance of our systems and other factors. We expect to pursue the expansion of our operations through internal growth and strategic partnerships.

23

Several key indicators of our liquidity are summarized in the following table:

(Dollars in thousands)	Years ended December 31,
	2005	2004	2003
Unrestricted cash, cash equivalents and marketable securities	$30,177	$40,223	$56,411

Purchase of property, plant and equipment	(1,004)	(1,834)	(1,070)

From inception through December 31, 2005, the Company has incurred net losses of $81.718 million and expects to incur losses as it continues micro fuel cell product development and commercialization programs. The Company expects that losses will fluctuate from year to year and that such fluctuations may be substantial as a result of, among other factors, sales of securities available for sale and the operating results of MTI Instruments and MTI Micro.

Critical Accounting Policies and Significant Judgments and Estimates

The Company's discussion and analysis of its financial condition and results of operations is based upon the Company's consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States of America. Note 1 to the consolidated financial statements includes a summary of the Company's most significant accounting policies. The preparation of these financial statements requires the Company to make estimates and judgments that affect the reported amounts of assets, liabilities, atrevenues and expenses, and related disclosure of assets and liabilities. On an on-going basis, the Company evaluates its estimates and judgments, including those related to revenue recognition, inventories, securities available for sale, income taxes and derivatives. Management bases its estimates on historical experience and on various other factors that are believed to be reasonable under the circumstances, the results of which form the basis for making jud gments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions. Management discussed our critical accounting estimates with our Audit Committee.

The significant accounting policies that management believes are most critical to aid in fully understanding and evaluating our reported financial results include the following:

Revenue Recognition: The Company recognizes revenue from development contracts based upon the relationship of actual costs to estimated costs to complete the contract. These types of contracts typically provide development services to achieve a specific scientific result relating to DMFC technology. Some of these contracts require the Company to contribute to the development effort. The customers for these contracts are both commercial customers and various state and federal government agencies. When government agencies are providing revenue, we do not expect the government to be a significant end user of the resulting products. Therefore, the Company does not reduce funded research and product development expense by the funding received. When it appears probable that estimated costs will exceed available funding on fixed price contracts, and the Company is not successful in securing additional funding, the Company records the estimated additional expense before it is incurred. The Comp any had no accrual for contract losses for the year ended December 31:

(Dollars in thousands)	2003	2002
Balance, beginning of period	$ 54	$ 81
Accruals for warranties issued	55	54
Accruals related to pre-existing warranties (including
changes in estimates)	(66)	(66)
Settlements made (in cash or in kind)	(15)	(15)
Balance, end of period	$ 28	$ 54

Licenses31, 2005.

The Company licenses,recognizes revenue from product sales in accordance with Staff Accounting Bulletin ("SAB") No. 104,Revenue Recognition. Product revenue is recognized when there is persuasive evidence of an arrangement, delivery of the product to the customer or distributor has occurred, at which time title generally is passed to the customer or distributor, and the Company has determined that collection of a fixed fee is probable, all of which occur upon shipment of the product. If the product requires installation to be performed by the Company, all revenue related to the product is deferred and recognized upon the completion of the installation.

Inventory: Inventory is valued at the lower of cost or the current estimated market value of the inventory. We periodically review inventory quantities on hand and record a non-exclusive basis, certain Direct Methanol Fuel Cell ("DMFC") technology from Los Alamos National Laboratory. Under this agreement,provision for excess and/or obsolete inventory based primarily on our estimated forecast of product demand, as well as based on historical usage. Demand and usage for products and materials can fluctuate significantly. A significant decrease in demand for our products could result in a short-term increase in the cost of inventory purchases and an increase of excess inventory quantities on hand. Therefore, although we make every effort to ensure the accuracy of our forecasts of future product demand, any significant unanticipated changes in demand could have a significant impact on the value of our inventory and our reported operating results.

Income Taxes: As part of the process of preparing our consolidated financial statements, the Company is required to payestimate its income taxes in each of the jurisdictions in which it operates. This process involves the estimation of our actual current tax exposure

24

together with assessing temporary differences resulting from differing treatment of items for tax and accounting purposes. Included in this assessment is the determination of net operating loss carry forwards. These differences result in a net deferred tax asset. The Company must assess the likelihood that its deferred tax assets will be recovered from future minimumtaxable income and, to the extent that the Company believes that recovery is not likely, it must establish a valuation allowance.

Significant management judgment is required in determining our provision for income taxes, our deferred tax assets and liabilities and any valuation allowance recorded against our net deferred tax assets. We have recorded a valuation allowance due to uncertainties related to our ability to realize certain net deferred tax assets, primarily consisting of net operating losses being carried forward. In the event that actual results differ from these estimates or we adjust these estimates in future periods, we may need to adjust the recorded valuation allowance, which could materially impact our financial position and results of operations. The Company has recorded a $10.923 million valuation allowance against its net deferred tax assets of $10.900 million as of December 31, 2005. This valuation allowance is due to uncertainties related to our ability to realize certain of these assets. The valuation allowance is based on estimates of the recoverability of certain net operating losses. In the event actu al results differ from these estimates or we adjust these estimates in future periods we may need to adjust our valuation allowance which could materially impact our financial position and results of operations.

Derivative Instruments: The Company has held or issued certain derivative instruments and embedded derivative instruments and records these derivatives and embedded derivative instruments separate from the host contract in accordance with Statement of Financial Accounting Standards ("SFAS") No. 133,Accounting for Derivative Instruments and Hedging Activities, as amended by SFAS No. 138, Accounting for Certain Derivative Instruments and Certain Hedging Activities.These standards require the Company to recognize all derivative instruments as either assets or liabilities on the statement of financial position and measure these instruments at fair value. Fair values are estimated using the Black Scholes Option-Pricing Model. Fair value estimates are subject to significant change between periods due to fluctuations of the variables used in the model.

Discussion and Analysis of Results of Operations

Results of Operations for the Year Ended December 31, 2005 Compared to December 31, 2004:The following is management's discussion and analysis of certain significant factors, which have affected the Company's results of operations for the year ended December 31, 2005 compared to the year ended December 31, 2004.

Product Revenue:Product revenue in the Test and Measurement Instrumentation segment for 2005 decreased by $1.518 million, or 20.2%, to $6.012 million. This decrease is primarily the result of decreased sales to aviation customers of $1.014 million reflecting the September 2004 expiration of a U.S. Air Force contract which accounted for $1.447 million of product revenue in 2004; decreases of $.798 million in semiconductor product sales reflecting the shipment of seven manual units, one semi-automated unit and four OEM machines during 2005 as compared to twelve manual units, five semi-automated units, five OEM machines and two AutoScan units for the same period in 2004; partially offset by increases in sales to general gaging customers of $.294 million related to increases in capacitance product sales and an increase in business generated by the Company's Japanese distributor.

In the Test and Measurement Instrumentation segment, in 2005 the U.S. Air Force accounted for $2.385 million or 39.7% of product revenues; in 2004, the U.S. Air Force accounted for $3.508 million or 46.6% of product revenues.

Funded Research and Development Revenue:Funded research and development revenue in the New Energy segment for 2005 increased by $.789 million to $1.829 million, a 75.9% increase. This increase is the result of increases of $.751 million from the U.S. Department of Energy ("DOE"), $.250 million from the U.S. Army, $.224 million from the New York State Energy Development Authority ("NYSERDA"), $.150 million from the Harris Corporation ("Harris"), $.070 million from the U.S. Marine Corps partially offset by decreases from the National Institute of Standards and Technology ("NIST") contract's completion in 2004 when it contributed $.446 million, the Army Research Laboratories contract's completion in 2004 when it contributed $.200 million, and a $.010 million decrease from the Cabot Superior Micro Powders ("CSMP") NIST subcontract.

Contract Type A - Fixed Price Contract.

Contract Type B - Cost Shared Contract.

Cost of Product Revenue:Cost of product revenue in the Test and Measurement Instrumentation segment for the year ended December 31, 2005 decreased by $.496 million or 17.2% to $2.381 million. This decrease coincides with the lower sales volume for 2005 compared to the same period in 2004, which included lower aviation and semiconductor sales partially offset by increases in general gaging sales.

Gross profit as a percentage of product revenue decreased by 1.4% to 60.4% for the year ended December 31, 2005. This decrease is primarily attributable to the reduction in U.S. Air Force shipments.

Funded Research and Product Development Expenses:Funded research and product development expenses in the New Energy segment decreased by $.485 million, or 12.0%, to $3.555 million for the year ended December 31, 2005. The decreased costs were attributable to a change in contracts under development during 2005 and the completion of contracts during 2004. The majority of costs for 2005 were incurred under the DOE and NYSERDA contracts while the majority of costs for the comparable period were incurred under the NIST, ARL, Harris and U.S. Army contracts.

Unfunded Research and Product Development Expenses:Unfunded research and product development expenses for the year ended December 31, 2005 decreased by $2.804 million or 31.4% to $6.116 million. This decrease reflects a $2.780 million decrease for the New Energy segment reflecting decreased internal development costs for our micro fuel cell system for Intermec since the Intermec product was completed in the fourth quarter of 2004 and development costs in connection with Gillette, accounting for $2.379 million of the decrease. Although overall research and development spending on the Gillette initiative had decreased from the prior year, this was a planned decrease due to an increased emphasis on product identification and marketing requirements during 2005. This decrease also includes a $.024 million decrease for the Test and Measurement Instrumentation segment. Test and Measurement Instrumentation product development in 2005 includes costs for improvements for the Microtrak II product , a high temperature capacitance gauge to serve the brake rotor market and the development of balancing software for the industrial market.

26

Selling, General and Administrative Expenses:Selling, general and administrative expenses for the year ended December 31, 2005 totaled $10.887 million, an increase of $4.562 million or 72.1%. These increases are primarily the result of the following changes: a $.995 million increase in non-cash stock-based compensation charges; a $2.077 million increase in salary and benefits related, in some part, to an increase in engineering management costs not directly charged to research and product development, an increase in the number of employees working in government and military relations, strategic planning and business development as well as corporate support employees related to Sarbanes-Oxley compliance, an expanded sales organization at MTI Instruments and CEO and employee recruiting costs; increased costs of $.543 million related to consulting and other professional fees (including increases of approximately $.387 million of costs related to consultants for government relations, business dev elopment, finance and information technology, $.469 million of costs related to Sarbanes-Oxley compliance and the SEC review of the Company's filings, $.106 million of legal costs related to SEC and general corporate matters, partially offset by decreases of $.300 million in advisory fees and $.148 million in legal fees related to the 2004 private placement amendment); increased depreciation expense of $.341 million due to an increase in capital expenditures; an increase of $.130 million in licensing and patent fees related to agreements with LANL; increased costs of $.437 million related to costs which were liquidated to research and development costs in the prior year; and a $.039 million increase in other expenses, net.

Operating Loss:The year ended December 31, 2005 yielded an operating loss of $15.098 million, an increase of $1.506 million from 2004, or 11.1%. This change results primarily from increases in selling, general and administration expense as well as decreases in gross profits from product revenues in the Test and Measurement Instrumentation segment partially offset by increases in funded research and development revenue in the New Energy segment and decreases in funded and unfunded research and product development expenses.

Gain on Sale of Securities Available for Sale:Results for the year ended December 31, 2005 included a $10.125 million gain compared to the prior year ended December 31, 2004, gain of $3.626 million. During 2005, the Company sold 100,000 shares of Plug Power common stock at a price of $6.68 per share, with proceeds to the Company of $.668 million. On June 24, 2005, Fletcher notified the Company of its election to exercise in full its right to purchase from the Company certain shares of common stock of Plug Power. As a result of this election, Fletcher purchased 1,799,791 shares of Plug Power common stock from the Company at a price of $0.7226 per share, with proceeds to the Company of $1.301 million. This transaction closed on June 28, 2005 and, in connection with this exercise, the Company recognized a loss on the derivative immediately prior to exercise of $7.173 million and a gain on the sale of Plug Power common shares of $9.635 million.

(Loss) Gain on Derivatives:The Company recorded a loss of $10.407 million and a gain of $.614 million on derivative accounting for 2005 and 2004, respectively. These results relate to the embedded derivative for the purchase of Plug Power common stock, which is part of the 2004 private placement transaction, and the January 2004 expiration of the SatCon warrants. Changes in derivative fair values for the embedded derivative and the SatCon warrants are calculated using the Black Scholes Option-Pricing model or upon exercise the intrinsic value method.

Income Tax (Expense) Benefit:The income tax expense rate for the year ended December 31, 2005 was 11% compared to the income tax benefit rate for the year ended December 31, 2004 of 39%. These tax rates are primarily due to losses generated by operations, changes in the valuation allowance and the projected annual licenseeffective tax rate adjustments.

The Company established a valuation allowance of $10.923 million at December 31, 2005 compared to $1.836 million at December 31, 2004. The Company determined that it was more likely than not that the ultimate recognition of certain deferred tax assets would not be realized.

Further, as a result of ownership changes in 1996, the availability of $.561 million of net operating loss carry-forwards to offset future taxable income will be limited pursuant to the Internal Revenue Code of 1986, as amended.

Results of Operations for the Year Ended December 31, 2004 Compared to December 31, 2003: The following is management's discussion and analysis of certain significant factors, which have affected the Company's results of operations for the year ended December 31, 2004 compared to the year ended December 31, 2003.

Product Revenue:Product revenue in the Test and Measurement Instrumentation segment for 2004 increased in comparison to the same period in 2003 by $1.983 million, or 35.7%, to $7.530 million. This increase is primarily the result of an increase in sales to aviation customers of $1.203 million, reflecting an increase in shipments under two Air Force contracts and a $.782 million increase in semiconductor product sales, which includes shipments of the first two AutoScans and two 300 SA wafer metrology tools.

In the Test and Measurement Instrumentation segment, the U.S. Air Force accounted for $3.508 million or 46.6% of

product revenues in 2004; as compared to 2003, where the U.S. Air Force accounted for $2.261 million or 40.8% of product revenues.

MTI Micro shipped its initial low volume production commercial product to a customer who plans to offer an RFID tag reader powered by a Mobion^® fuel cell. MTI Micro's initial shipments of low volume production Mobion^®products is a customer specific arrangement that includes fuel cell systems and continued warranty support. While contract terms require payment upon delivery of the fuel cell system and are not contingent on the achievement of specific milestones or other substantive performance, the continuing obligation to warranty results in deferring recognition of product-related revenue and recognizing product-related revenue when the warranty obligations expire. The warranty on the product is for a period of fifteen months.

As MTI Micro gains commercial experience, including field experience relative to warranty based on the sales of its initial low volume production Mobion^® products, in future periods, MTI Micro may recognize product-related revenue upon delivery of the product or may continue to defer recognition, based on application of appropriate guidance within SAB 104, or changes in the manner contractual agreements are structured, including agreements with distribution partners.

Funded Research and Development Revenue:Funded research and development revenue in the New Energy segment for 2004 decreased in comparison to the same period in 2003 by $1.271 million to $1.040 million, a 55.0% decrease. The decrease is the result of the NIST and NYSERDA government contracts contributing $1.381 million less revenue in 2004 compared to 2003 due to the completion of Phase II of the NYSERDA contract in the fourth quarter of 2003 and the wind down of the NIST contract during the third quarter of 2004. Harris revenues of $.175 million and other military contractor revenue of $.204 million were also recorded in 2003. These decreases were partially offset by $.489 million in 2004 revenues under new contracts with ARL, CSMP and DOE.

Cost of Product Revenue:Cost of product revenue in the Test and Measurement Instrumentation segment for 2004 increased in comparison to the same period in 2003 by $.495 million, or 20.8%, to $2.877 million. The increase was directly due to the higher sales volume for 2004 and its product mix, which during 2004 included the shipment of two AutoScan metrology tools which had reduced carrying values due to the weak semiconductor market conditions over the last two years.

Gross profit as a percentage of product revenue increased to 61.8% for 2004 from 57.1% in the prior year. The gross profit percentage increase was primarily due to a five point increase in PBS product margins resulting from pricing escalations built into both U.S. Air Force contracts. Additionally, in general instruments, capacitance products showed a nine point increase in margins resulting from decreased material costs and improved assembly efficiencies. All of the other product lines showed at least a two point improvement in margins over the prior year. Further adding to the current year's improvement was the sale of two AutoScan metrology tools, which had reduced carrying values due to the weak semiconductor market conditions over the previous two years.

Funded Research and Product Development Expenses:Funded research and product development expenses in the New Energy segment increased by $.277 million or 7.4% to $4.040 million for 2004 in comparison to the same period in 2003.

The increased costs were attributable to the development of prototypes for Harris and costs incurred under new contracts with ARL for the delivery of micro fuel cell units and CSMP and DOE for the advancement of the consumer DMFC platform. Expenses were further increased by an accrual of estimated losses on contracts totaling $557 thousand. This accrual was required because, during 2004, MTI Micro entered into a fixed price-cost-type completion contract with the U.S. Army for $250 thousand and the forecast to complete this project exceeds the funding by $540 thousand and the forecast to complete another fixed price contract exceeded costs incurred through December 31, 2004 by $17 thousand. These costs were partially offset by decreased development costs related to the completion of the Phase II of the NYSERDA contract during 2003 and reduced costs related to the NIST contract as it was winding down during the third quarter of 2004.

Unfunded Research and Product Development Expense: Unfunded research and product development expenses increased by $4.335 million or 94.5% to $8.920 million for 2004 in comparison to the same period in 2003. This increase reflects a $4.251 million increase in the New Energy segment reflecting increased internal development costs directed at commercializing micro fuel cells, including costs for the development of our micro fuel cell system and development costs in connection with Gillette and potential commercial products. Unfunded research and product development costs include the cost of micro fuel cell products shipped due to the initial fuel cell units being low volume production. Cost of micro fuel cell products includes the direct material cost incurred in the manufacture of the products we ship. These costs consist primarily of production materials and fees paid to outside suppliers for subcontracted components and services. This increase also includes a $.084 million increase i n product development expenses in the Test and Measurement Instrumentation segment related to the continued development of the PBS-3300 and MTI-2100. The PBS-3300 is a smaller test cell system used for small turbines and props and the MTI-2100 is the newest version of the fiber-optic based vibration sensor.

Selling, General and Administrative Expenses:Selling, general and administrative expenses increased by $.488 million to $6.325 million for 2004 in comparison to the same period in 2003. This change is primarily the result of an increase of $.294 million in professional fees related to the Fletcher amendment, increased public relations costs of $.167 million, increased insurance costs of $.248 million, increased depreciation expense of $.186 million due to an increase in capital expenditures offset by a decrease in professional fees of (dollars$.427 million due to a business transaction that occurred during 2003.

Operating Loss:Operating loss for 2004 in thousands): $200comparison to the same period last year increased by $4.883 million to $13.592 million, a 56.1% increase. This increase in operating loss results primarily from increases in research and product development expenses and selling, general and administration expenses and decreases in funded research and development revenue in the New Energy segment partially offset by increases in gross profits from product revenues in the Test and Measurement Instrumentation segment.

Other Income: Revenue from sales of micro fuel cell products was $0 million for the years ended December 31, 2004 and $250December 31, 2003. We defer recognition of initial micro fuel cell product-related revenue at the time of delivery and recognize this revenue as other income as the continued warranty obligations expire. The costs associated with the product and warranty obligations are expensed as they are incurred.

Our initial sales of low volume production Mobion^®products are a customer specific arrangement that includes fuel cell systems and continued warranty support. While contract terms require payment upon delivery of the System and are not contingent on the achievement of specific milestones or other substantive performance, the continuing obligation to warranty results in 2005. the Company deferring recognition of product-related revenue and recognizing product-related revenue as other income when the warranty obligations expire. The warranty on the product is for a period of fifteen months.

29

During the fourth quarter of 2004, we received a purchase order for 50 Systems and delivered 25 Systems during December 2004. The product-related revenue associated with these 25 Systems is subject to warranty obligations and has been deferred. For the year ended December 31, 2004, we deferred revenue in the amount of $3,125 for these Systems. We had no System sales in 2003.

Gain on Sale of Securities Available for Sale:Results for 2004 included a $3.626 million gain on the sale of securities available for sale compared to a $7.483 million gain for the same period in 2003. The average selling price per share of Plug Power common stock was $9.33 for 2004. The average selling price per share of Plug Power and SatCon common stock was $5.07 and $1.75, respectively, for 2003.

Gain (Loss) on Derivatives:The Company recorded a gain of $.614 million and a loss of $.006 million on derivative accounting for 2004 and 2003, respectively. The 2004 gain relates to the embedded derivative for the purchase of Plug Power common stock, which is part of the 2004 private placement transaction, while the loss in 2003 related to warrants for the purchase of SatCon common stock held by the Company. Changes in derivative fair values for the embedded derivative and the SatCon warrants are calculated using the Black Scholes Option-Pricing Model.

Impairment Losses:In 2004 and 2003, the Company recorded a $0 and $.418 million charge for impairment losses for other than temporary declines in the value of certain securities available for sale.

Income Tax Benefit:The income tax benefit rate for 2004 and 2003 was 39%. The tax benefit rates are primarily due to losses generated by operations. The valuation allowance at December 31, 2004 and 2003 was $1.836 million. The Company determined that it was more likely than not that the ultimate recognition of certain deferred tax assets would not be realized.

Further, as a result of ownership changes in 1996, the availability of $1.014 million of net operating loss carry-forwards to offset future taxable income will be limited pursuant to the Internal Revenue Code.

Liquidity and Capital Resources

The Company has incurred significant losses as it continues to fund MTI Micro's DMFC product development and commercialization programs. The Company expects that losses will fluctuate from year to year and that such fluctuations may be substantial as a result of, among other factors, sales of securities available for sale, the operating results of MTI Instruments and MTI Micro, the availability of equity financing including the additional investment rights issued in connection with the 2004 private placement and the ability to attract government funding resources to offset research and development costs. As of December 31, 2005, the Company had an accumulated deficit of $81.718 million. During the year ended December 31, 2005, the Company's results of operations resulted in a net loss of $15.094 million and used cash in operating activities totaling $12.572 million. This cash use in 2005 was funded primarily by cash and cash equivalents on hand as of December 31, 2004 of $22.545 million. The Compa ny expects to continue to incur losses as it seeks to develop and commercialize Mobion^®fuel cell systems and it expects to continue funding its operations from current cash and cash equivalents, the sales of securities available for sale, proceeds, if any, from the exercise of additional investment rights issued in connection with the 2004 private placement or other equity financings and government program funding. The Company expects to spend approximately $7.8 million on research and development of Mobion^® fuel cells and $1.1 million in research and development on MTI Instruments' products during 2006.

There can be no assurance that the Company will not require additional financing during 2006 or that any additional financing will be available to the Company on terms acceptable to the Company, if at all. Cash used in operations is expected to total approximately $16.0 million for 2006. Further, cash used for capital expenditures is expected to total approximately $2.5 million in 2006 and will consist of purchases for leasehold improvements, furniture, computer equipment, software and manufacturing and laboratory equipment. The Company believes it will have adequate resources to fund operations and capital expenditures through the second quarter of 2007 based on current cash and cash equivalents, current cash flow and revenue projections and the potential sale of securities available for sale at current market values. Proceeds from the sale of securities available for sale are subject to fluctuations in the market value of Plug Power. The Company may also seek to provide additional resources through an equity offering. Additional government revenues and Fletcher's potential exercise of additional investment rights totaling up to an additional $20 million could also provide additional resources, although with an exercise price of $6.023 per share it is unlikely that Fletcher will exercise its right unless our stock price increases. The Company anticipates that it will have to raise additional equity capital to fund its long-term business plan, regardless of whether Fletcher exercises any or all of its additional investment rights.

30

As of December 31, 2005, the Company owned 3,693,436 shares of Plug Power common stock.

Potential future sales of Plug Power securities will generate taxable income or loss, which is different from book income or loss, due to the tax bases in these assets being significantly different from their book bases. Book and tax bases as of December 31, 2005 are as follows:

		Average	Average
Security	Shares Held	Book Cost Basis	Tax Basis
Plug Power	3,693,436	$1.78	$0.96

Plug Power stock is currently traded on the Nasdaq National Market and is therefore subject to stock market conditions. When acquired, these securities were unregistered. Plug Power securities are considered "restricted securities" as defined in Rule 144 and may not be sold in the future without registration under the Securities Act, unless in compliance with an available exemption there from.

Working capital was $24.465 million at December 31, 2005, a $10.347 million decrease from $34.812 million at December 31, 2004. This decrease is primarily the result of the use of cash in operations offset by increases in the market value and proceeds from sale of securities available for sale.

At December 31, 2005, the Company's order backlog was $.862 million, compared to $.480 million at December 31, 2004.

Inventory and accounts receivable (from product revenues) turnover ratios and their changes for the last two annual periods are as follows for the years ended December 31:

	2005	2004	Change
Inventory	2.00	2.10	(.10)
Accounts receivable (from product revenues)	8.94	9.60	(.66)

The changes in the inventory and accounts receivable turnover ratios are the result of the volume and timing of sales. The Test and Measurement Instrumentation segment had lower monthly sales in December 2005 compared to December 2004.

Cash flow used by operating activities was $12.572 million in 2005 compared with $11.982 million in 2004. This cash use increase of $.590 million reflects increases in cash expenditures to fund operations at the New Energy segment, partially offset by balance sheet changes, which reflect the timing of cash payments and receipts.

Capital expenditures were $1.004 million in 2005, a decrease of $.830 million from the prior year. Capital expenditures in 2005 included computer equipment, demonstration equipment, software, and manufacturing and laboratory equipment. Outstanding commitments for capital expenditures as of December 31, 2005 totaled $129 thousand and include expenditures for lab and production equipment, leasehold improvements and computer equipment. The Company expects to finance these expenditures with current cash and cash equivalents, the sale of securities available for sale, equity financing and other sources, as appropriate and to the extent available.

Pursuant to additional investment rights, Fletcher has 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 $6.023 (as adjusted from $6.34), which date and price may be extended and adjusted, respectively, in certain circumstances.

During 2005, the Company sold 1,899,791 shares of Plug Power common stock with proceeds totaling $1.969 million and gains totaling $10.125 million. These proceeds reflect the Company's previously announced strategy to raise additional capital through the sale of Plug Power stock in order to fund its micro fuel cell operations as well as Fletcher's exercise of its right to purchase Plug Power common stock from the Company. Taxes on the net gains are expected to be offset by the Company's operating losses. As of December 31, 2005, the Company estimates its remaining net operating loss carry forwards to be approximately $39.115 million.

The Agreement is subject to confidential treatment as filed with the SEC.

Employment Agreements(C) Under the NYSERDA contract, MTI Micro agreed to pay NYSERDA a royalty of 1.5% of the sales price of any product sold incorporating IP developed pursuant to the NYSERDA contract if the product is manufactured by a New York State manufacturer. This royalty increases to 5% if the manufacturer is not deemed to be a New York State manufacturer. In any event, the royalty is subject to a cap equal to two times the total contract funds paid by NYSERDA to MTI Micro as reduced to reflect any New York State jobs created by MTI Micro.

Off-Balance Sheet Arrangements

Pursuant to a financing transaction entered into between the Company and Fletcher on January 29, 2004, Fletcher has 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 $6.023 (as adjusted from $6.34), which date and price may be extended and adjusted, respectively, in certain circumstances. Fletcher also has the right to receive Company shares without payment upon the occurrence of certain events, including but not limited to, failing to register for resale with the SEC shares purchased by Fletcher on the agreed upon time table, a restatement of the Company's financial statements, change of control of the Company and issuance of securities at a price below Fletcher's purchase price. We have filed registration statements covering all of the shares purchased by Fletcher to date and in the event of any additional purchases we are similarly obli gated to file one or more registration statements covering resale of such shares. In Connection with the late effective date for the registration statement filed on January 6, 2004, the Company issued and registered 66,413 shares of common stock to Fletcher without any additional payment. At December 31, 2005, Fletcher owned 393,515 shares or 1.3% of the Company's common stock.

Effect of Recent Accounting Pronouncements: In November 2004, the FASB issued SFAS No. 151,Inventory Costs-an amendment of ARB No. 43, Chapter 4("FAS 151"), which is the result of its efforts to converge U.S. accounting standards for inventories with International Accounting Standards. SFAS No. 151 requires idle facility expenses, freight, handling costs and wasted material (spoilage) costs to be recognized as current-period charges. It also requires that allocation of fixed production overheads to the costs of conversion be based on the normal capacity of the production facilities. SFAS No. 151 will be effective for inventory costs incurred during fiscal years beginning after June 15, 2005. The Company does not believe that the impact of this standard will have a material effect on the Company's consolidated financial statements.

In December 2004, the FASB issued SFAS No. 123 (Revised 2004)Share-Based Payment ("SFAS No. 123R"), which is a revision of FASB SFAS No. 123,Accounting for Stock-Based Compensation. SFAS No. 123R addresses all forms of share-based payment ("SBP") awards, including shares issued under employee stock purchase plans, stock options, restricted stock and stock appreciation rights. In March 2005 the SEC issued Staff Accounting Bulletin No. 107 (SAB 107). SAB 107 expresses views of the SEC staff regarding the interaction between SFAS 123R and certain SEC rules. SFAS 123R focuses primarily on accounting for transactions in which an entity obtains employee services in share-based payment transactions. SFAS 123R requires public entities to measure the cost of employee services received in exchange for an award of equity instruments based on the grant-date fair value of the award. The grant-date fair value of employee share options and similar instruments will be estima ted using option-pricing models adjusted for the unique characteristics of those instruments. That cost will be recognized over the period during which an employee is required to provide service in exchange for the award. In April 2005, the SEC delayed the implementation of SFAS 123R for

32

public companies until the first annual period beginning after June 15, 2005. SFAS 123R is required to be adopted by the Company as of January 1, 2006. The Company has not yet determined the impact of applying the various provisions of SFAS No. 123R. The effects of adopting this standard will depend on our future stock option activity and the term of the options.

The Company currently utilizes a closed form option-pricing model to measure the fair value of stock-based compensation for employees. SFAS 123R permits the use of this model or other models such as a lattice model. The Company has determined that it will use the Black-Scholes Option-Pricing model to measure the fair value of share-based grants to employees upon the adoption of SFAS 123R. The effect of expensing stock options in accordance with the original SFAS 123 is presented above. SFAS 123R also requires that the benefits associated with the tax deductions in excess of recognized compensation cost be reported as a financing cash flow, rather than as an operating cash flow as required under current literature. This presentation may reduce net operating cash flows and increase net financing cash flows in periods after the effective date. The amount of this excess tax deduction benefit was $0 thousand and $294 thousand in the twelve months ended December 31, 2005 and 2004, respectively. The unvested val ue of share awards to be amortized into the operating statement is approximately $1.494 million as of December 31, 2005.

In December 2004, the FASB issued SFAS No. 153, Exchanges of Non-monetary Assets, an amendment of APB Opinion No. 29. SFAS No. 153 addresses the measurement of exchanges of non-monetary assets and redefines the scope of transactions that should be measured based on the fair value of the assets exchanged. SFAS No. 153 is effective for non-monetary asset exchanges in fiscal periods beginning after June 15, 2005. The Company does not believe that the impact of this standard will have a material effect on the Company's consolidated financial statements.

In March 2005, the FASB issued FASB Interpretation No. 47 Accounting for Conditional Asset Retirement Obligations, which is an interpretation of FASB Statement No. 143, Account for Asset Retirement Obligations. The interpretation requires a liability for the fair value of a conditional asset retirement obligation be recognized if the fair value of the liability can be reasonably estimated. The interpretation is effective for years ending after December 15, 2005. The Company does not believe that the impact of this standard will have a material effect on the Company's consolidated financial statements.

In May 2005, SFAS No. 154, Accounting Changes and Error Corrections - replacement of APB Opinion No. 20 and FASB Statement No. 3, (SFAS No. 154) was issued. SFAS No. 154 changes the accounting for and reporting of a change in accounting principle by requiring retrospective application to prior periods' financial statements of changes in accounting principle unless impracticable. SFAS No. 154 is effective for accounting changes made in fiscal years beginning after December 15, 2005. The Company does not believe that the impact of this standard will have a material effect on the Company's consolidated financial statements.

In June 2005, the FASB's Emerging Issues Task Force ("EITF") reached a consensus on Issue No. 05-6, Determining the Amortization Period for Leasehold Improvements (EITF 05-6). The guidance requires that leasehold improvements acquired in a business combination or purchased subsequent to the inception of a lease be amortized over the lesser of the useful life of the assets or a term that includes renewals that are reasonably assured at the date of the business combination or purchase. The guidance is effective for periods beginning after June 29, 2005. The adoption of EITF 05-6 did not have a significant effect on the Company's consolidated financial statements.

Item 7A: Quantitative and Qualitative Disclosures about Market Risk

We develop products in the United States and sell them worldwide. As a result, our financial results could be affected by factors such as changes in foreign exchange rates or weak economic conditions in foreign markets. Since our sales are currently priced in U.S. dollars and are translated to local currency amounts, a strengthening of the dollar could make our products less competitive in foreign markets. Interest income is sensitive to changes in the general level of U.S. interest rates, particularly since our investments are in cash equivalents. Based on the nature and current levels of our cash equivalents, however, we have concluded that there is no material market risk exposure.

As a result of holding securities available for sale, the Company is exposed to fluctuations in market value. The Company recognizes changes in market value through the balance sheet, however if an other than temporary market decline were to occur, it could have a material impact on the Company's operating results.

The Company's issued derivatives have consisted of warrants and rights to purchase shares of the Company's common stock and Plug Power common stock owned by the Company. The fair value of the embedded derivative for the right to purchase Plug Power common stock was recorded in the financial statement line titled "Derivative liability" until its exercise date during June 2005. This

33

derivative was valued quarterly using the Black Scholes Option-Pricing Model. The Company's held derivatives consisted of warrants to purchase SatCon common stock. These held derivatives expired on January 31, 2004. The fair value of the warrants to purchase SatCon common stock was based on estimates using the Black Scholes Option-Pricing Model. The Company recognizes changes in fair value through the operating statement line titled "Gain (loss) on derivatives." The Company does not use derivative financial instruments for speculative or trading purposes.

Market risk represents the risk of changes in value of a financial instrument caused by fluctuations in interest rates and equity prices. The Company has performed a sensitivity analysis on its investments in Plug Power and its derivative financial instrument (Plug Power Investment Right). The sensitivity analysis presents the hypothetical change in fair value of the Company's financial investments as of the balance sheet date. Market risk is estimated as the potential change in fair value resulting from an immediate hypothetical one-percentage point parallel shift in the yield curve. The fair values of the Company's holdings in securities available for sale have been based on quoted market prices and its derivative financial instruments based on estimates using valuation techniques.

The fair market and estimated values of the Company's investments in Plug Power and derivatives and the calculated impact of a market price decrease of ten percent, is as follows:

(Dollars in thousands)

	Holdings/	Estimated	Ten Percent
Balance at	Derivatives	Fair Market Value	Market Decrease
December 31, 2005	Plug Power	$ 18,947	$1,895
December 31, 2004	Plug Power	$ 34,175	$ 3,418
	Derivative	$ 1,125	$ 113

Item 9: Changes in and Disagreements with Accountants on Accounting and Financial Disclosure

None.

Item 9A: Controls and Procedures

(a) Evaluation of Disclosure Controls and Procedures

Evaluation of Disclosure Controls and Procedures: The Company's management, with the participation of the Company's chief executive officer and chief financial officer, evaluated the effectiveness of the Company's disclosure controls and procedures as of December 31, 2005. The term "disclosure controls and procedures," as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, means controls and other procedures of a company that are designed to ensure that information required to be disclosed by a company in the reports that files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC's rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the company's management, including its principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Based on the valuation of the Company's disclosure controls and procedures as of December 31, 2005, the Company's chief executive officer and chief financial officer concluded that, as of such date, the Company's disclosure controls and procedures were effective at the reasonable assurance level.

Changes in Internal Control over Financial Reporting: There have been no changes in the Company's internal control over financial reporting, as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act, during the Company's fiscal quarter ended December 31, 2005 that have materially affected, or are reasonable likely to materially affect, the Company's internal control over financial reporting.

(b) Management's Report on Internal Control Over Financial Reporting

Management of the Company is responsible for establishing and maintaining adequate internal control over financial reporting, as that term is defined in Exchange Act Rules 13a-15(f) and 15d-15(f). The Company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Under the supervision and with the participation of the Company's management, including the principal executive officer and principal financial officer, the Company conducted an evaluation of the effectiveness of its internal control over financial reporting using the criteria set forth inInternal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on our evaluation using the criteria set forth inInternal Control-Integrated Framework,our management concluded that our internal control over financial reporting was effective as of December 31, 2005.

Our management's assessment of the effectiveness of the Company's internal control over financial reporting as of December 31, 2005 has been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in their report, which is included herein at page F-2.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Shareholders of

Mechanical Technology Incorporated

We have completed integrated audits of Mechanical Technology Incorporated's 2005 and 2004 consolidated financial statements and of its internal control over financial reporting as of December 31, 2005, and an audit of its 2003 consolidated financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Our opinions, based on our audits, are presented below.

Consolidated financial statements

In our opinion, the consolidated financial statements listed in the accompanying index present fairly, in all material respects, the financial position of Mechanical Technology Incorporated and its subsidiaries at December 31, 2005 and 2004 and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2005 in conformity with accounting principles generally accepted in the United States of America. These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit of financial statements includes examining, on a test basis, evi dence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

Internal control over financial reporting

Also, in our opinion, management's assessment, included in Management's Report on Internal Control over Financial Reporting appearing under Item 9A, that the Company maintained effective internal control over financial reporting as of December 31, 2005 based on criteria established inInternal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO), is fairly stated, in all material respects, based on those criteria. Furthermore, in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2005, based on criteria established inInternal Control - Integrated Framework issued by the COSO. The Company's management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting. Our responsibility is to express opinions on management's assessment an d on the effectiveness of the Company's internal control over financial reporting based on our audit. We conducted our audit of internal control over financial reporting in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. An audit of internal control over financial reporting includes obtaining an understanding of internal control over financial reporting, evaluating management's assessment, testing and evaluating the design and operating effectiveness of internal control, and performing such other procedures as we consider necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinions.

A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the comp any's assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

1. Nature of Operations

Description of Business

Mechanical Technology Incorporated, ("MTI" or the "Company"), a New York corporation, was incorporated in 1961. MTI operates in two segments, the New Energy segment which is conducted through MTI MicroFuel Cells Inc. ("MTI Micro"), a majority-owned subsidiary, and the Test and Measurement Instrumentation segment, which is conducted through MTI Instruments, Inc. ("MTI Instruments"), a wholly owned subsidiary.

At its MTI Micro subsidiary, the Company is primarily focused on the development and commercialization of advanced cord-free rechargeable power pack technology for portable electronics. MTI Micro has developed a patented, proprietary direct methanol fuel cell ("DMFC") technology called Mobion^®, which generates electrical power using up to 100% methanol as fuel. MTI Micro's Mobion^® technology is intended to replace current lithium-ion and similar rechargeable battery systems currently used by original equipment manufacturers (OEMs) in many hand held electronic devices such as PDAs, Smartphones and different accessories. The Company formed MTI Micro as a subsidiary on March 26, 2001 and currently owns approximately 90% of the outstanding common stock of MTI Micro.

At its MTI Instruments subsidiary, the Company designs, manufactures, and sells high-performance test and measurement instruments and systems. MTI Instruments was incorporated as a subsidiary on March 8, 2000 and has three product groups: general dimensional gaging, semiconductor and aviation. These products consist of electronic, computerized gaging instruments for position, displacement and vibration applications for the design, manufacturing and test markets; semiconductor products for wafer characterization of semi-insulating and semi-conducting wafers for the semiconductor market; and engine balancing and vibration analysis systems for both military and commercial aircraft.

Liquidity

The Company has employment agreementsincurred significant losses as it continues to fund MTI Micro's DMFC product development and commercialization programs. The Company expects that losses will fluctuate from year to year and that such fluctuations may be substantial as a result of, among other factors, sales of securities available for sale, the operating results of MTI Instruments and MTI Micro, the availability of equity financing including the additional investment rights issued in connection with the 2004 private placement and the ability to attract government funding resources to offset research and development costs. The Company expects to continue to incur losses as it seeks to develop and commercialize Mobion^®fuel cell systems and it expects to continue funding its operations from current cash and cash equivalents, the sales of securities available for sale, proceeds, if any, from the exercise of additional investment rights issued in connection with the 2004 private placement or other equity financ ings and government program funding. The Company may also seek to provide additional resources through an equity offering. Additional government revenues and Fletcher's potential exercise of additional investment rights totaling up to an additional $20 million could also provide additional resources although with an exercise price of $6.023 per share it is unlikely that Fletcher will exercise its right unless our stock price increases. The Company anticipates that it will have to raise additional equity capital to fund its long-term business plan, regardless of whether Fletcher exercises any or all of its additional investment rights.

Pursuant to additional investment rights, Fletcher has 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 $6.023 (as adjusted from $6.34), which date and price may be extended and adjusted, respectively, in certain employees that provide severance paymentscircumstances.

During 2005, the Company sold 1,899,791 shares of Plug Power common stock with proceeds totaling $1.969 million and accelerated vestinggains totaling $10.125 million. These proceeds reflect the Company's previously announced strategy to raise additional capital through the sale of certain options upon terminationPlug Power stock in order to fund its micro fuel cell operations as well as Fletcher's exercise of employment under certain circumstances, as definedits right to purchase Plug Power common stock from the Company.

 At December 31, 2005, the Company had cash, cash equivalents and securities available for sale in the applicable agreements. Asamount of $30.177 million and working capital of $24.465 million. The failure to raise the funds necessary to finance our future cash requirements or consummate future acquisitions could adversely affect the Company's ability to pursue its strategy and could negatively affect the Company's operations in future periods.Management believes it will have adequate resources to fund operations and capital expenditures for at least the next twelve months based on current cash and cash equivalents, current cash flow and revenue projections and the potential sale of securities available for sale at current market values.

2. Accounting Policies

Principles of Consolidation

The consolidated financial statements include the accounts of the Company and its majority-owned subsidiaries. All significant intercompany transactions are eliminated in consolidation.

Minority interest in subsidiaries consists of equity securities issued by a subsidiary of the Company. No gain or loss was recognized as a result of the issuance of these securities, and the Company owned a majority of the voting equity of the subsidiary both before and after the transactions. The Company reflects the impact of the equity securities issuances in its investment in subsidiary and additional paid-in-capital accounts for the dilution or anti-dilution of its ownership interest in the subsidiary.


Use of Estimates

The preparation of the consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Fair Value of Financial Instruments

The Company's financial instruments consist of cash and cash equivalents, marketable securities, accounts receivable, unbilled contract costs and fees, warrants to purchase shares of common stock (which expired January 31, 2004) and accounts payable. The estimated fair value of these financial instruments approximate their carrying values at December 31, 2005 and 2004. The estimated fair values have been determined through information obtained from market sources, where available, or Black-Scholes Option-Pricing model valuations.

Accounting for Derivative Instruments

The Company accounts for derivative instruments and embedded derivative instruments in accordance with Statement of Financial Accounting Standards ("SFAS") No. 133,Accounting for Derivative Instruments and Hedging Activities, as amended by SFAS No. 138,Accounting for Derivative Instruments and Certain Hedging Activities,which establishes a model for accounting for derivatives and hedging activities. These standards require an entity to recognize all derivatives as either assets or liabilities in the statement of financial position and measure these instruments at fair value. Fair value is estimated using the Black Scholes Option-Pricing model. The Company also follows Emerging Issues Task Force ("EITF") Issue No. 00-19,Accounting for Derivative Financial Instruments Indexed to and Potentially Settled in, a Company's Own Stock, which requires freestanding contracts that are settled in a company's own stock, including common stock warrants, to be designat ed as an equity instrument, asset or a liability. Under the provisions of EITF Issue No. 00-19, a contract designated as an asset or a liability must be carried at fair value, with any changes in fair value recorded in the results of operations. A contract designated as an equity instrument must be included within equity, and no fair value adjustments are required.

The Company held or has outstanding as of December 31, 2003,the following derivative financial instruments:

	2005	2004	Expiration
Derivatives issued:
Warrants, exercisable beginning February 5, 2005, to purchase the Company's common
stock issued to Chicago Investment Group, L.L.C. at a purchase price of $10.572 per share	28,377	28,377	February 5, 2006
Second Investment Right, exercisable beginning December 22, 2004, to purchase the Company's
common stock issued to Fletcher International, Ltd. at a purchase price of $6.023 per share
through December 31, 2006(1)(3)	3,320,604	3,154,575	December 31, 2006
Plug Power Investment Right, exercisable at any time from June 1, 2005 through
December 31, 2006 to purchase a number of the Company's shares of Plug Power common
stock (to the extent of the number of shares remaining in escrow pursuant to the agreement)
equal to $10,000,000 divided by the prevailing price per share of Plug Power common stock(1)	-	(2)	December 31, 2006

(1) The Company and Fletcher International, Ltd. entered into an amended private placement agreement on May 4, 2004 (see Note 11 - Shareholders' Equity).

(2) The exercise price for the Plug Power Investment Right was $10,000,000 less the positive difference between $18,000,000 and the product of the 2,680,671 shares 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 (see Note 11- Shareholders' Equity). This right was fully exercised on June 24, 2005.

(3)The Company incurred a registration penalty during March 2005, which resulted in a reduction in the exercise price for the Second Investment Right from $6.34 to $6.023 per share.

The Plug Power Investment Right is legally detached and separate. In accordance with EITF 00-19, since this contract is indexed not only to MTI's stock but also to Plug Power's stock and it settles in Plug Power stock and not MTI stock, this contract is not solely indexed to the Company's potential minimumstock in accordance with the guidance in EITF 01-6 and as a result is a derivative. The contract meets the definition of a derivative under paragraph 6 of FAS 133. Management considered whether or not the contract would be eligible for a scope exception described in paragraph 11.a. of FAS 133 relating to instruments indexed to a company's own stock and determined that the contract is not eligible for this scope exception.

The Second Investment Right meets the criteria of SFAS No. 133, paragraph 11, as well as guidance in EITF 00-19 and EITF 01-06. The Right is indexed to the Company's stock and requires settlement in shares and because this right was part of the initial Fletcher investment, it is part of the original investment's fair value and is recorded as permanent equity and is not separately valued.


The Plug Power Investment Right, prior to its exercise, was valued on a quarterly basis using the Black-Scholes Option Pricing model and upon its exercise on June 24, 2005 was valued using the intrinsic value method. Significant assumptions used in the valuation included exercise dates, closing stock prices for the common stock of MTI and Plug Power, volatility of the common stock of MTI and Plug Power, risk-free interest rate and estimated number of shares in escrow. (Losses) gains on derivatives are included in "(Loss) gain on derivatives" in the Consolidated Statements of Operations.

On June 24, 2005, Fletcher International, Ltd. ("Fletcher") notified the Company of Fletcher's election to exercise in full its right to purchase from the Company certain shares of common stock of Plug Power. As a result of this election, Fletcher purchased 1,799,791 shares of Plug Power common stock from the Company at a price of $0.7226 per share, with proceeds to the Company of $1.301 million. This transaction closed on June 28, 2005 and, in connection with this exercise, the Company recognized a loss on the derivative immediately prior to exercise of $7.173 million and a gain on the sale of Plug Power common shares of $9.635 million.

Accounts Receivable and Allowance for Doubtful Accounts

Trade accounts receivable are recorded at the invoiced amount and do not bear interest. The allowance for doubtful accounts is our best estimate of the amount of probable credit losses in our existing accounts receivable. We determine the allowance based on historical write-off experience and current exposures identified. We review our allowance for doubtful accounts monthly. Past due balances over 90 days and over a specified amount are reviewed individually for collectibility. All other balances are reviewed on a pooled basis by type of receivable. Account balances are charged off against the allowance when we feel it is probable the receivable will not be recovered. We do not have any off-balance-sheet credit exposure related to our customers.

Inventories

Inventories are valued at the lower of cost (first-in, first-out) or market. The Company provides estimated inventory allowances for excess, slow moving and obsolete inventory as well as inventory whose carrying value is in excess of net realizable value.

Property, Plant, and Equipment

Property, plant and equipment are stated at cost and depreciated using primarily the straight-line method over their estimated useful lives:

Leasehold improvements	Lesser of the life of the lease or the useful life of the improvement
Machinery and equipment	2 to 10 years
Office furniture, equipment and fixtures	2 to 10 years

Significant additions or improvements extending assets' useful lives are capitalized; normal maintenance and repair costs are expensed as incurred. The costs of fully depreciated assets remaining in use are included in the respective asset and accumulated depreciation accounts. When items are sold or retired, related gains or losses are included in net income (loss).

Income Taxes

The Company accounts for taxes in accordance with SFAS No. 109,Accounting for Income Taxes, which requires the

use of the asset and liability method of accounting for income taxes. Under the asset and liability method, deferred income taxes are recognized for the tax consequences of "temporary differences" by applying enacted statutory tax rates applicable for future years to differences between financial statement and tax bases of existing assets and liabilities. Under SFAS No. 109, the effect of tax rate changes on deferred taxes is recognized in the income tax provision in the period that includes the enactment date. The provision for taxes is reduced by investment and other tax credits in the years such credits become available. A valuation allowance is recorded to reduce the carrying amounts of deferred tax assets unless it is more likely than not that such assets will be realized.

Revenue Recognition

The Company applies the guidance within SEC Staff Accounting Bulletin ("SAB") No. 104,Revenue Recognitionin the evaluation of its contracts to determine when to properly recognize revenue. Under SAB No. 104, revenue is recognized when title and risk of loss have passed to the customer, there is persuasive evidence of an arrangement, the fee is fixed or determinable, delivery has occurred or services have been rendered, the sales price is determinable, and collectibility is reasonably assured.

Product Revenue

Product revenue is recognized when there is persuasive evidence of an arrangement, the collection a fixed fee is probable or determinable, delivery of the product to the customer or distributor has occurred, at which time title generally is passed to the customer or distributor, all of which generally occur upon shipment of the product. If the product requires installation to be performed by the Company, all revenue related to the product is deferred and recognized upon the completion of the installation. If the product requires specific customer acceptance, revenue is deferred until customer acceptance occurs or the acceptance provisions lapse, unless the Company can objectively and reliably demonstrate that the criteria specified in the acceptance provisions are satisfied.

The Company defers recognition of its initial micro fuel cell product-related revenue at the time of delivery and recognizes revenue as the continued warranty obligations expire. The costs associated with the product and warranty obligations are expensed as they are incurred. The Company's initial shipment during 2004 of its micro fuel cell product is a customer specific arrangement that includes fuel cell systems and continued warranty support. While contract terms require payment upon delivery of the fuel cell system and are not contingent on the achievement of specific milestones or other substantive performance, the continuing obligation to thesewarranty the product results in the Company deferring recognition of product-related revenue and recognizing product-related revenue when the warranty obligations expire. The warranty on the product is for a period of fifteen months. When micro fuel cell product-related revenue qualifies for revenue recognition it will be recorded in the Consolidated Statements of Operations in the line titled "Other income (expense), net."

As the Company gains commercial experience, including field experience relative to warranty based on the sales of its initial products, in future periods, the Company may recognize product-related revenue upon delivery of the product or may continue to defer recognition, based on application of appropriate guidance within SAB No. 104, or changes in the manner contractual agreements are structured, including agreements with distribution partners.

MTI Instruments, Inc. ("MTI Instruments"), a wholly-owned subsidiary of MTI, currently has distributor agreements in place for (1) the domestic sale of its semiconductor products and (2) for the international sale of general instrument and semiconductor products in certain global regions.  Such agreements grant a distributor the right of first refusal to act as distributor for such products in the distributor's territory.  In return, the distributor agrees to not market other products which are considered by MTI Instruments to be in direct competition with MTI Instruments' products. The distributor is allowed to purchase MTI Instruments' equipment at a price which is discounted off the published domestic/international list prices. Such list prices can be adjusted by MTI Instruments during the term of the distributor agreement, but MTI Instruments must provide advance notice at least 90 days before the price adjustment goes into effect.  Generally, pa yment terms with the distributor are standard net 30 days; however, on occasion, extended payment terms have been granted.  Title to the product passes to the distributor upon delivery to the independent carrier (standard FOB factory), and the distributor is responsible for any required training and/or service with the end-user.  The sale (and subsequent payment) between MTI Instruments and the distributor is not contingent upon the successful resale of the product by the distributor.  Distributor sales are covered by MTI Instruments' standard one-year warranty and there are no special return policies for distributors.

Some of MTI Instruments' direct sales, particularly sales of semi-automatic and fully-automated semiconductor metrology equipment, involve on-site customer acceptance and/or training.  In those instances, revenue recognition does not take place at time of shipment.  Instead, MTI Instruments recognizes the sale after the unit is installed and/or training is performed and an on-site acceptance is given by the customer.  Agreed-upon acceptance terms and conditions, if any, are negotiated at the time of purchase. 

Funded Research and Development Revenue

The Company performs funded research and development for government agencies and commercial companies under both cost reimbursement and fixed-price contracts.  Cost reimbursement contracts provide for the reimbursement of allowable costs.  On fixed-price contracts, revenue is generally recognized on the percentage of completion method based upon the proportion of costs incurred to the total estimated costs for the contract. Revenue from reimbursement contracts is recognized as the services are performed. In each type of contract, the Company generally receives periodic progress payments or payments upon reaching interim milestones. When the current estimates of total contract revenue for commercial development contracts indicate a loss, a provision for the entire loss on the contract is recorded. Any losses incurred in performing funded research and development projects are recognized as research and development expense as incurred. When government agencies are providing funding they do not expect the government to be the only significant end user of the resulting products.  These contracts do not require delivery of products that meet defined performance specifications, but are best efforts arrangements to achieve overall research and development objectives. Included in accounts receivable are billed and unbilled work-in-progress on contracts. Billings in excess of contract revenues earned are recorded as deferred revenue. While the Company's accounting for government contract costs is subject to audit by the sponsoring entity, in the opinion of management, no material adjustments are expected as a result of such audits. Adjustments are recognized in the period made.

Contract Type A - Fixed Price Contract.

Contract Type B - Cost Shared Contract.

The Company's cost-shared contracts require that the Company's subsidiary MTI MicroFuel Cells Inc. ("MTI Micro") conduct research and deliver direct methanol micro fuel cell ("DMFC") prototypes pursuant to predefined work plans and schedules. The contracts with NIST, NYSERDA and the DOE result in the following total multi-year contract expenditures by MTI Micro: $6,696,968, $2,702,080 and $6,144,094, and are expected to or have resulted in total multi-year funding of $3,342,085, $1,249,736 and $1,175,000 respectively.

MTI Micro retains ownership of the intellectual property ("IP") generated under each of its federal government contracts and under contracts with Harris and CSMP. Each federal government agency retains a government use license and march-in rights if MTI Micro fails to commercialize technology generated under the contract. In addition, under the NYSERDA contract, MTI Micro has the right to elect to retain any invention made under the NYSERDA contract within six months of invention. NYSERDA also retains rights to a government use license for New York State and its political subdivisions for any inventions made under the contract. In addition, MTI Micro agreed to pay NYSERDA a royalty of 1.5% of the sales price of any product sold incorporating IP developed pursuant to the NYSERDA contract if the product is manufactured by a New York State manufacturer. This royalty increases to 5% if the manufacturer is not deemed to be a New York State manufacturer. In any event, the royalty is subject to a cap equal to two times the total contract funds paid by NYSERDA to MTI Micro as reduced to reflect any New York State jobs created by MTI Micro.

Cost of Product Revenue

Cost of product revenue includes material, labor and overhead. Costs incurred in connection with funded research and development arrangements are included in funded research and product development expenses.

Deferred Revenue

Deferred revenue consists of payments received from customers in advance of services performed, products shipped, installation completion or customer acceptance.

Warranty

The Company records a warranty reserve at the time product revenue is recorded based on a historical rate. The reserve is reviewed during the year and is adjusted, if appropriate, to reflect new product offerings or changes in experience. Actual warranty claims are tracked by product line.

Accounting for Goodwill and Other Intangible Assets

Intangible assets include patents and trade names. Goodwill and other intangible assets are accounted for in accordance with SFAS No. 142,Goodwill and Other Intangible Assets. Intangible assets with finite useful lives are amortized over those periods. Indefinite lived intangible assets will be tested for impairment annually, and will be tested for impairment between annual tests if an event occurs or circumstances change that would indicate that the carrying amount may be impaired. Definite lived assets are tested for impairment whenever events or circumstances indicate that a carrying amount of an asset may not be recoverable. An impairment loss would be recognized when the carrying amount of an asset exceeds the estimated undiscounted cash flows used in determining the fair value of the asset. The amount of the impairment loss to be recorded is calculated by the excess of the assets carrying value over its fair value. Fair value is generally determined using a discounted cash flow analysi s. Costs related to internally-developed intangible assets are expensed as incurred.

Accounting for Impairment or Disposal of Long-Lived Assets

The Company accounts for impairment or disposal of long-lived assets in accordance with SFAS No. 144,Accounting for the Impairment or Disposal of Long-Lived. This Statement addresses financial accounting and reporting for the impairment or disposal of long-lived assets and specifies how impairment will be measured and how impaired assets will be classified in the consolidated financial statements.

Cash and Cash Equivalents

Cash and cash equivalents consist of cash and highly liquid short-term investments with original maturities of less than three months.

Securities Available for Sale

Management determines the appropriate classification of its investments in marketable securities at the time of purchase and reevaluates such determinations at each balance sheet date. Marketable securities for which the Company does not have the intent or ability to hold to maturity are classified as available for sale. Securities available for sale are carried at fair value, with the unrealized gains and losses, net of income taxes, reported as a separate component of shareholders' equity. The Company has had no investments that qualify as trading or held to maturity. Realized gains and losses are included in "Gain (loss) on sale of securities available for sale" in the Consolidated Statements of Operations. The cost of securities sold is based on the specific identification method.

Net (Loss) Income per Basic and Diluted Common Share

The Company reports net (loss) income per basic and diluted common share in accordance with SFAS No. 128,Earnings Per Share, which establishes standards for computing and presenting (loss) income per share. Basic (loss) income per share is computed by dividing net (loss) income attributable to common shareholders by the weighted-average number of common shares outstanding for the period. Diluted (loss) income per share reflects the potential dilution, if any, which would occur if securities or other contracts to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock that then shared in the (loss) income of the Company.

Stock Based Compensation

At December 31, 2005, the Company has two stock-based employee compensation plans and its majority-owned subsidiary, MTI Micro, has one stock-based employee compensation plan, which are described more fully in Note 13, Stock Based Compensation. SFAS No. 123,Accounting for Stock-Based Compensation, requires the measurement of the fair value of stock options or warrants granted to employees to be included in the Consolidated Statement of Operations or, alternatively, disclosed in the notes to consolidated financial statements. The Company accounts for stock-based compensation of employees under the intrinsic value method of APB Opinion No. 25,Accounting for Stock Issued to Employees, and related Interpretations and has elected the disclosure-only alternative under SFAS No. 123,Share-Based Paymentas amended by SFAS No. 148,Accounting for Stock-Based Compensation - Transition and Disclosure. The Company records the fair market value of stock options and warrants granted to non-employees in exchange for services in accordance with EITF No. 96-18,Accounting for Equity Instruments That Are Issued to Other Than Employees for Acquiring, or in Conjunction with Selling, Goods or Services, in the Consolidated Statement of Operations.

The following table illustrates the effect on net loss and loss per share as if the Company had applied the fair value recognition provisions of SFAS Statement No. 123,Accounting for Stock-Based Compensation, to stock-based employee compensation for each of the years ended December 31:

Advertising

The costs of advertising are expensed as incurred. Advertising expense was approximately $786 thousand.$45, $41 and $25 thousand in 2005, 2004 and 2003, respectively.

Concentration of Credit Risk

Financial instruments that subject the Company to concentrations of credit risk principally consist of cash equivalents, marketable securities, trade accounts receivable and unbilled contract costs.

The Company's trade accounts receivable and unbilled contract costs and fees are primarily from sales to commercial customers and U.S. government and state agencies. The Company does not require collateral and has not historically experienced significant credit losses related to receivables or unbilled contract costs and fees from individual customers or groups of customers in any particular industry or geographic area.

The Company deposits its cash and invests in marketable securities primarily through commercial banks and investment companies. Credit exposure to any one entity is limited by Company policy.

Research and Development Costs

The Company expenses research and development costs as incurred.

Comprehensive (Loss) Income

Comprehensive (loss) income includes net (loss) income, as well as changes in shareholders' equity, other than those resulting from investments by shareholders (i.e., issuance or repurchase of common shares and dividends).

Effect of Recent Accounting Pronouncements

In November 2004, the FASB issued SFAS No. 151,Inventory Costs-an amendment of ARB No. 43, Chapter 4("FAS 151"), which is the result of its efforts to converge U.S. accounting standards for inventories with International Accounting Standards. SFAS No. 151 requires idle facility expenses, freight, handling costs and wasted material (spoilage) costs to be recognized as current-period charges. It also requires that allocation of fixed production overheads to the costs of conversion be based on the normal capacity of the production facilities. SFAS No. 151 will be effective for inventory costs incurred during fiscal years beginning after June 15, 2005. The Company does not believe that the impact of this standard will have a material effect on the Company's consolidated financial statements.

In December 2004, the FASB issued SFAS No. 123 (Revised 2004)Share-Based Payment ("SFAS No. 123R"), which is a revision of FASB SFAS No. 123,Accounting for Stock-Based Compensation. SFAS No. 123R addresses all forms of share-based payment ("SBP") awards, including shares issued under employee stock purchase plans, stock options, restricted stock and stock appreciation rights. In March 2005 the SEC issued Staff Accounting Bulletin No. 107 (SAB 107). SAB 107 expresses views of the SEC staff regarding the interaction between SFAS 123R and certain SEC rules. SFAS 123R focuses primarily on accounting for transactions in which an entity obtains employee services in share-based payment transactions. SFAS 123R requires public entities to measure the cost of employee services received in exchange for an award of equity instruments based on the grant-date fair value of the award. The grant-date fair value of employee share options and similar instruments will be estima ted using option-pricing models adjusted for the unique characteristics of those instruments. That cost will be recognized over the period during which an employee is required to provide service in exchange for the award. In April 2005, the SEC delayed the implementation of SFAS 123R for public companies until the first annual period beginning after June 15, 2005. SFAS 123R is required to be adopted by the Company as of January 1, 2006. The Company has not yet determined the impact of applying the various provisions of SFAS No. 123R. The effects of adopting this standard will depend on our future stock option activity and the term of the options.

The Company currently utilizes a closed form option-pricing model to measure the fair value of stock-based compensation for employees. SFAS 123R permits the use of this model or other models such as a lattice model. The Company has determined that it will use the Black-Scholes model to measure the fair value of share-based grants to employees upon the adoption of SFAS 123R. The effect of expensing stock options in accordance with the original SFAS 123 is presented above. SFAS 123R also requires that the benefits associated with the tax deductions in excess of recognized compensation cost be reported as a financing cash flow, rather than as an operating cash flow as required under current literature. This presentation may reduce net operating cash flows and increase net financing cash flows in periods after the effective date. The amount of this excess tax deduction benefit was $0 thousand

and $294 thousand in the twelve months ended December 31, 2005 and 2004, respectively. The unvested value of share awards to be amortized into the operating statement is approximately $1.494 million as of December 31, 2005.

In December 2004, the FASB issued SFAS No. 153, Exchanges of Non-monetary Assets, an amendment of APB Opinion No. 29. SFAS No. 153 addresses the measurement of exchanges of non-monetary assets and redefines the scope of transactions that should be measured based on the fair value of the assets exchanged. SFAS No. 153 is effective for non-monetary asset exchanges in fiscal periods beginning after June 15, 2005. The Company does not believe that the impact of this standard will have a material effect on the Company's consolidated financial statements.

In March 2005, the FASB issued FASB Interpretation No. 47, Accounting for Conditional Asset Retirement Obligations, which is an interpretation of FASB Statement No. 143, Accounting for Asset Retirement Obligations. The interpretation requires a liability for the fair value of a conditional asset retirement obligation be recognized if the fair value of the liability can be reasonably estimated. The interpretation is effective for years ending after December 15, 2005. The Company does not believe that the impact of this standard will have a material effect on the Company's consolidated financial statements.

In May 2005, SFAS No. 154, Accounting Changes and Error Corrections - replacement of APB Opinion No. 20 and FASB Statement No. 3, (SFAS No. 154) was issued. SFAS No. 154 changes the accounting for and reporting of a change in accounting principle by requiring retrospective application to prior periods' financial statements of changes in accounting principle unless impracticable. SFAS No. 154 is effective for accounting changes made in fiscal years beginning after December 15, 2005. The Company does not believe that the impact of this standard will have a material effect on the Company's consolidated financial statements.

In June 2005, the FASB's Emerging Issues Task Force ("EITF") reached a consensus on Issue No. 05-6, Determining the Amortization Period for Leasehold Improvements (EITF 05-6). The guidance requires that leasehold improvements acquired in a business combination or purchased subsequent to the inception of a lease be amortized over the lesser of the useful life of the assets or a term that includes renewals that are reasonably assured at the date of the business combination or purchase. The guidance is effective for periods beginning after June 29, 2005. The adoption of EITF 05-6 did not have a significant effect on the Company's consolidated financial statements.

GuarantyRetroactive Adjustments and Revision

The financial statements for all prior periods have been retroactively adjusted to reflect the change in par value of Subsidiary Fundingthe Company's common stock (See Note 11).

4. Issuance of Stock by Subsidiary

MTI Micro was formed on March 26, 2001 and as of December 31, 2005, the Company owns approximately 90% of MTI Micro's outstanding common stock.

On December 31, 2005, as a result of the MTI and MTI Micro option exchange (see Note 11 - Shareholders' Equity), MTI Micro issued 105,701 shares of its common stock at a price of $2.22 per share to the Company as compensation for minority shareholder benefit in connection with the Strategic Alliance Agreement betweentransaction.

On April 7, 2004, MTI Micro sold 3,218,885 and 215,000 shares of MTI Micro common stock to the Company and a group of private investors, respectively, at a price of $4.66 per share for approximately $15 million and $1 million, respectively. Further, on May 20, 2004, MTI Micro sold 215,000 shares of MTI Micro common stock to a private investor at a price of $4.66 per share for approximately $1 million.


On September 19, 2003, MTI Micro entered into a strategic alliance agreement with Gillette whereby Gillette purchased 1,088,278 shares (362,760 post 2004 1 for 3 reverse split) of MTI Micro common stock at a price of $.92 ($2.76 post 2004 1 for 3 reverse split) per share for $1 million pursuant to an equity investment agreement (the "Investment Agreement"). In addition to the foregoing referenced $1 million investment in MTI Micro common stock, Gillette may make additional investments in its subsidiary, MTI Micro, of up to $4 million subject to agreed milestones. The Company agreed to invest $20 million in MTI Micro before September 19, 2005 if other sources of funding are not available. Immediately prior to the Gillette transaction closing, the Company invested $11 million ($7.4 million in cash and $3.6 million through the conversion of a loan receivable to equity) of its $20 million commitment in MTI Micro common stock.

19. Commitments and Contingencies(Continued)

Investment Company Act

The Company's securities available for sale constitute investment securities under the Investment Company Act of 1940 (the "Investment Company Act"). In general, a company may be deemed to be an investment company if it owns investment securities with a value exceeding 40% of its total assets, subject to certain exclusions and exemptions. Investment companies are subject to registration under, and compliance with, the Investment Company Act unless a particular exemption or safe harbor provision applies. If the Company were to be deemed an investment company, the Company would become subject to the requirements of the Investment Company Act. As a consequence, the Company would be prohibited from engaging in certain businesses or issuing certain securities, certain of our contracts might be voidable, and the Company might be subject to civil and criminal penalties for noncompliance.

Until fiscal 2001, the Company qualified for a safe harbor exemption under the Investment Company Act based upon the level of ownership of shares of Plug Power and influence over its management or policies. However, since the Company sold some of its shares of Plug Power during fiscal 2001, this safe harbor exemption may not be available.

On December 3, 2001, the Company made an application to the Securities and Exchange Commission ("SEC") requesting that they either declare that the Company is not an investment company because it is primarily engaged in another business or exempt it from the provisions of the Investment Company Act for a period of time. The Company amended this application on October 20, 2003. This application is pending. If the Company's application is not granted, the Company will have to find another safe harbor or exemption that it can qualify for, which may include a one-year safe harbor granted by the Investment Company Act, or become an investment company subject to the regulations of the Investment Company Act.

If the Company was deemed to be an investment company and could not find another safe harbor or exemption and failed to register as an investment company, the SEC could require the Company to sell its interest in Plug Power until the value of its securities available for sale are reduced below 40% of total assets. This could result in sales of securities in quantities of shares at depressed prices and the Company may never realize anticipated benefits from, or may incur losses on, these sales. Also, in connection with the strategic alliance agreement with2003 Gillette the Company has agreed to indemnify Gillette against any losses arising outtransaction, MTI Micro converted its Junior Convertible Preferred Class A and Senior Convertible Preferred Class B stock into common stock and treasury stock of or related to the Company's noncompliance with the Investment Company Act or any regulations thereunder.

Further, the Company may be unable to sell some securities due to contractual or legal restrictions or the inability to locate a suitable buyer. Moreover, the Company may incur tax liabilities when selling assets.

On October 29, 2003, Jeong Kim, a member of the board of directors of MTI Micro, investedpurchased 1,088,278 (362,760 post 2004 1 for 3 reverse split) shares of MTI Micro common stock at a price of $.92 ($2.76 post 2004 1 for 3 reverse split) per share for $1 millionmillion.

The (decrease) increase in the Company's paid-in-capital of $(99), $351 and $881 thousand in 2005, 2004 and 2003, respectively, represents the changes in the Company's equity investment in MTI Micro, (see Note 3).

On September 19, 2003, Gillette invested $1 millionwhich resulted from the (anti-dilutive)/dilutive impact of the Company's investments into and third-party stock transactions in MTI Micro pursuant to a strategic alliance agreement (see Notes 3 and 24).

20. Related Party Transactions (Continued)

The Company had an ownership interest in Beacon Power from 2000 to December 30, 2002. Associated with this ownership, the Company received approximately $183 thousand in preferred stock dividends from Beacon Power during fiscal 2001.

On September 28, 2001, the Company received 544,148 shares of Beacon Power Common Stock as a pro rata distribution by SatCon. The Company recognized a gain of $827 thousand on this dividend distribution.

On December 27, 2000, the Company entered into a Put and Call with FAC to provide independent credit support for repayment of the then outstanding KeyBank loan ("FAC Credit Enhancement") for which the Company paid a fee of $945 thousand. The FAC Credit Enhancement provided FAC with the option, if the price of Plug Power stock fell to $4 per share, to either purchase 6.3 million Plug Power shares pledged as collateral on the loan or take an assignment of KeyBank, N.A.'s rights under the $50 million Amended and Restated Credit Agreement. The FAC Credit Enhancement could be triggered in the event of a default and was amended on April 27, 2001, the original expiration date, to extend its expiration date to August 27, 2001. The Company paid a fee of $200 thousand for this amendment. The Company and FAC could renew the FAC Credit Enhancement on a monthly basis upon mutually agreeable terms. If the FAC Credit Enhancement expired, and was not replaced, prior to November 3, 2001, the loan would be im mediately due and payable. Upon expiration of the FAC Credit Enhancement, mandatory repayments on any outstanding balance would be required if the Plug Power stock price fell below $20 per share. The FAC Credit Enhancement expired on August 27, 2001 and was not replaced since the Company amended and restated its Credit Agreement with KeyBank, N.A. on August 10, 2001, the $10 million Credit Agreement. The new KeyBank, N.A. agreement did not require a credit enhancement.

On December 27, 2000, the Company entered into two bridge loan agreements with FAC. The first loan was for $945 thousand and was used

to pay the purchase price for the FAC Credit Enhancement. The Company

pledged 200,000 shares of Plug Power common stock as collateral. The second loan was for $5 million, $3 million of which was used to make a

December 27, 2000 principal loan repayment to KeyBank, N.A. and the

remaining $2 million was available for working capital. The Company

pledged 1 million shares of Plug Power common stock as collateral. Upon

mutual agreement of FAC and the Company, the loans may be converted to equity prior to maturity. Both loans bore interest at the Prime Rate and both interest and principal were due on January 3, 2002. On March 30, 2001, the Company made a principal payment to FAC totaling $4 million. On April 30, 2001, the Company made principal and interest payments to FAC totaling $1.445 million and $.117 million, respectively, which reduced the Company's obligations on the FAC Bridge Loans to zero.

The 2005 valuation allowance reflects the estimate that it is more likely than not that the net deferred tax assets may not be realized. The 2004 valuation allowance reflects the estimate that it is more likely than not that certain net operating losses may be unavailable to offset future taxable income.

Sale of Common Stock

Private Placement

OnPlacement: The Company entered into a financing transaction with Fletcher International, Ltd. ("Fletcher"), on January 29, 2004 we issued toand amended the terms of such transaction on May 4, 2004. To date Fletcher International, Ltd., or Fletcher, in a private placement (1) 1,418,842has purchased 2,680,671 shares of our common stock for an aggregate purchase price of $10$18 million orpursuant to such financing transaction - 1,418,842 shares at $7.048 per share and (2) rights1,261,829 shares at $6.34 per share. In addition, Fletcher has the right to purchase up to an additional $26$20 million of ourthe Company's 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 intend to use the proceeds of the private placement primarily to support the operations of MTI Micro and other general corporate purposes. We agreed to file with the SEC a registration statement within thirty (30) days following such issuance 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 acquire in the future upon exercise of its additional investment rightson one or upon the occurrence of certain other events. We filed such registration statement with the SEC on February 3, 2004.

Additional Investment Rights

The 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 ninety business days after the effective date of the registration statement,more occasions, at a price of $6.023 (adjusted from $6.34) per share equal to $7.048. 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 $18 million of our common stock at any time prior to December 31, 2006, which2006. Fletcher also has the right to receive Company shares without payment upon the occurrence of certain events, including but not limited to, failing to register for resale with the SEC shares purchased by Fletcher on the agreed upon time table, a restatement of the Company's financial statements, change of control of the Company and issuance of securities at a price below Fl etcher's purchase price. We have filed registration statements covering all of the shares purchased by Fletcher to date, may be extendedand in the event thatof any additional purchases we are obligated to file one or more registration statements covering the resale of such shares.

We filed a registration statement on January 6, 2005 covering the resale of 1,261,829 shares of our common stock purchased by Fletcher on December 22, 2004. The Company failed to meet its contractual obligation with Fletcher to have not satisfied our contractual obligations with respectsuch registration statement declared effective by March 22, 2005 and therefore under the terms of the Fletcher agreement we were required to theregistration for resaleissue additional shares of common stock issued or issuable to Fletcher. If Fletcher exercises suchand the exercise price for the Fletcher additional investment rights priorhas been reduced to $6.023 per share. We were required to issue a number of shares of common stock that resulted in Fletcher having effectively made its December 31, 2005, the2004 investment shall be at a per share price equal to $7.048.

After December 31, 2005 (including during any extension of the original investment term), the investment right shall be at a price per share equalthat was lower than the actual price paid. We refer to this reduced exercise price as the "deemed exercise price." More specifically, for each month during which we fail to satisfy the registration requirement, the deemed exercise price is reduced by $0.317 per share. As a consequence, on April 20, 2005 w e issued 66,413 shares of common stock to Fletcher without any additional payment required by Fletcher, representing a deemed exercise price for Fletcher's December 2004 investment of $6.023 per share. In addition, since we are required to file a registration statement covering the resale of any such additional shares issued to Fletcher, we amended the registration statement initially filed in January 2005 to include the additional 66,413 shares of common stock. That registration statement, covering the resale of 1,328,242 shares of common stock, was declared effective by the SEC on April 21, 2005.

Plug Power Shares: On June 24, 2005, Fletcher notified the Company of its election to exercise in full its right to purchase from the Company certain shares of common stock of Plug Power. As a result of this election, Fletcher purchased 1,799,791 shares of Plug Power common stock from the Company at a price of $0.7226 per share, with proceeds to the lesserCompany of $7.048$1.301 million. This transaction closed on June 28, 2005 and, in connection with this exercise, the Company recognized a loss on the derivative immediately prior to exercise of $7.173 million and a gain on the sale of Plug Power common shares of $9.635 million.

The Company had placed 2,700,000 shares of Plug Power common stock in escrow that were available for purchase by Fletcher in certain instances. Fletcher could, on one or multiple occasions, from June 1, 2005 to December 31, 2006, 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 (as defined below) per share of Plug Power common stock, but only to the extent of the number of shares remaining in escrow. Commencing immediately after the SEC declared effective on May 20, 2004 the registration statement relating to shares of our common stock owned by Fletcher, we had 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 as of five business days priorexceeds $6.343 (which price may have been adjusted to reflect stock splits, recombinations, stock dividends or the deliverylike).

The exercise price for the Plug Power investment right was $10,000,000 less the positive difference between $18,000,000 and the product of the sum of 2,680,671 shares multiplied by the prevailing price per share of our common stock on the date Fletcher elected to exercise notice.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 elected to exercise such right.

Plug Power Shares

At the time of the consummation of theAdjustment Provisions: The 2004 private placement we deposited into escrow 3,000,000 shares of common stock of Plug Power owned by us. Commencing immediately after the SEC declares effective the registration statement relating to shares of our common stock that Fletcher owns or may acquire, 250,000 of such shares will be 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 be 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 shall be released from escrow to us. If, however, Fletcher does exercise such right, then at any time during the month of June 2005, Fletcher may purchase from us a number of shares of Plug Power common stock equal to $10,000,000 divided by the prevailing price per share of Plug Power common s tock, 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

The number of shares which may be awarded under the 1996 Plan may be increased by 10% of any increase in the number of outstanding shares of common stock for reasons other than shares issued under this 1996 Plan. The number of shares which may be awarded under the 1996 Plan and awards outstanding have been adjusted for stock splits and rights offerings, and during 2005, 2004 and 2003, the total number of shares which may be awarded under the 1996 Plan were 3,746,813, 3,478,746 and 3,478,746 shares, respectively.

arrangements provided by the Company, namely, broad-based employee stock purchase plans and option grants where the exercise price is equal to or not less than 85 percent of the market value at the date of grant. However, APB Opinion No. 25 requires recognition of compensation expense for variable award plans over the vesting periods of such plans, based upon the then-current market values of the underlying stock. In contrast, SFAS No. 123 requires recognition of compensation expense for grants of stock, stock options, and other equity instruments, over the vesting periods of such grants, based on the estimated grant-date fair values of those grants.

Under the intrinsic-value-based method, compensation cost is the excess, if any, of the market value of the stock at grant over the amount an employee must pay to acquire the stock.

On December 30, 2005, the Company issued options to acquire 1,021,213 shares of MTI common stock, par value $0.01 per share, to certain employees, officers and directors of MTI and MTI MicroFuel Cells Inc. who previously held MTI Micro options (the "Optionees").

Litigation

Lawrence: On September 9, 1998, Barbara Lawrence, the Lawrence Group, Inc. ("Lawrence"), and certain other Lawrence-related entities ("Plaintiffs") initially filed suit in the Bankruptcy Court and the United States District Court for the Northern District of New York which were subsequently consolidated in the District Court, against First Albany Corporation ("FAC"), Mechanical Technology, Dale Church, Edward Dohring, Beno Sternlicht, Alan Goldberg and George McNamee (former Directors of the Company), Marty Mastroianni (former President and Chief Operating Officer of the Company), and 33 other individuals ("Defendants") who purchased a total of 820,909 (2,462,727 shares post split) shares of the Company's stock from the Plaintiffs. The case concerns the Defendants' 1997 purchase of Mechanical Technology shares from the Plaintiffs at the price of $2.25 per share ($0.75 per share post split). FAC acted as Placement Agent for the Defendants in the n egotiation and sale of the shares and in proceedings before the Bankruptcy Court for the Northern District of New York, which approved the sale in September 1997.

Plaintiffs claim that the Defendants failed to disclose material inside information concerning Plug Power, LLC to the Plaintiffs and therefore the $2.25 per share ($0.75 per share post split) purchase price was unfair. Plaintiffs are seeking damages of $5 million plus punitive damages and costs. In April 1999, Defendants filed a motion to dismiss the amended complaint, which was denied by the Bankruptcy Court. On appeal in October 2000, Plaintiffs' cause of action was dismissed by the United States District Court for the Northern District of New York. In November 2000, Plaintiffs filed an appeal of that dismissal with the United States Court of Appeals for the Second Circuit. In June 2002, the Second Circuit Court of Appeals reversed the District Court decision and remanded the case for further consideration of the Plaintiff's claims as motions to modify the Bankruptcy Court sale order. The Plaintiff's claims have now been referred back to Bankruptcy Court for such consideration. In September 2003, th e Bankruptcy Court issued an order permitting Plaintiffs to conduct limited discovery concerning how First Albany formed an opinion about the Company's stock up until the date the Stock Purchase Agreement was executed. Discovery has commenced.

The Company believes the claims have no merit and intends to defend them vigorously.The Company cannot predict theoutcome of the claims nor reasonably estimate a range of possible loss given the current status of the litigation. Accordingly, no amounts have been reserved for this matter.

Leases

The Company and its subsidiaries lease certain manufacturing, laboratory and office facilities. The leases generally provide for the Company to pay either an increase over a base year level for taxes, maintenance, insurance and other costs of the leased properties or the Company's allocated share of insurance, taxes, maintenance and other costs of leased properties. The leases contain renewal provisions.

Future minimum rental payments required under non-cancelable operating leases are (dollars in thousands): $327 in 2006, $322 in 2007, $319 in 2008, $289 in 2009 and $0 in 2010. Rent expense under all leases was $746, $706 and $636 thousand for 2005, 2004 and 2003, respectively. Contingent rent included in the rent expense amounts was $11, $53 and $46 thousand for 2005, 2004 and 2003, respectively.

Warranties

Accruals for warranties issued	30	38
Accruals related to pre-existing warranties (including changes in estimates)	(31)	(16)
Settlements made (in cash or in kind)	(17)	(12)
Balance, end of period	$ 20	$ 38

Licenses

The Company licenses, on a non-exclusive basis, certain DMFC technology from Los Alamos National Laboratory ("LANL"). Under this agreement, the Company is required to pay future minimum annual license fees of $250 thousand yearly through 2019.

Effective, July 6, 2005, MTI Micro entered into an exclusive field-of-use patent license agreement with LANL. Under this agreement, MTI Micro paid a non-refundable License Issue Fee of $30 thousand upon execution of the agreement.

Under both LANL licenses, license payments made in any year can be applied against royalties due and total annual fees in any year shall not exceed $1 million. Also under both LANL licenses, once products are being sold, royalties will be based on 2% of the first $50 million of net sales, 1% on net sales in excess of $50 million but less than $100 million and .5% on net sales in excess of $100 million Any royalties due shall not exceed 2% of net sales.

Under the NYSERDA contract, MTI Micro agreed to pay NYSERDA a royalty of 1.5% of the sales price of any product sold incorporating IP developed pursuant to the NYSERDA contract if the product is manufactured by a New York State manufacturer. This royalty increases to 5% if the manufacturer is not deemed to be a New York State manufacturer. In any event, the royalty is subject to a cap equal to two times the total contract funds paid by NYSERDA to MTI Micro as reduced to reflect any New York State jobs created by MTI Micro.

Employment Agreements

The Company has employment agreements with certain employees that provide severance payments, certain other payments, accelerated vesting and exercise extension periods of certain options upon termination of employment under certain circumstances, as defined in the applicable agreements. As of December 31, 2005, the Company's potential minimum obligation to these employees was approximately $751 thousand.

Guaranty Under Gillette Agreement

The Company agreed not to assert any defenses that it might have arising out of or related to the Investment Company Act ("Investment Company Defense") to any "claim, action, cause of action, suit, litigation, arbitration, charge, complaint, demand, notice or proceeding

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

brought by Gillette, and to defend, indemnify and hold Gillette and the Gillette indemnities harmless for all losses arising out of or related to non-compliance with the Investment Company Act. Because the Company has already paid the full amount of the $20 million guarantee under the agreement and agreed not to assert an Investment Company Defense, the Company's liability pursuant to this indemnification is likely to be zero. Further, on July 18, 2005 the Company withdrew its application to the SEC requesting that they either declare that the Company is not an investment company because it is primarily engaged in another business or exempt it from the provisions of the Investment Company Act. Following discussions and other communications with the SEC staff in which the staff expressed the view that the application was no longer necessary. Since the value of the Company's interests in Plug Power has decreased in relation to its total assets, the Company believes that it is not an investment company s ubject to the regulations of the Investment Company Act.

Investment Company Act

The Company's securities available for sale constitute investment securities under the Investment Company Act of 1940 (the "Investment Company Act"). In general, a company may be deemed to be an investment company if it owns investment securities with a value exceeding 40% of its total assets, subject to certain exclusions and exemptions.

Investment companies are subject to registration under, and compliance with, the Investment Company Act unless a particular exemption or safe harbor provision applies. If the Company were to be deemed an investment company, the Company would become subject to the requirements of the Investment Company Act. As a consequence, the Company would be prohibited from engaging in certain businesses or issuing certain securities, certain of the Company's contracts might be voidable, and the Company might be subject to civil and criminal penalties for noncompliance.

Until 2001, the Company qualified for a safe harbor exemption under the Investment Company Act based upon the level of its ownership of shares of Plug Power and its influence over Plug Power's management or policies. However, since the Company began selling shares of Plug Power, this safe harbor exemption is no longer available.

On December 3, 2001, the Company made an application to the SEC requesting that they either declare that the Company is not an investment company because it is primarily engaged in another business or exempt it from the provisions of the Investment Company Act. The Company amended this application on October 20, 2003. On July 18, 2005, the Company requested that the application be withdrawn following exhibitsdiscussions and other communications with the SEC staff in which the staff expressed the view that the application was no longer necessary. Since the value of the Company's interests in Plug Power has decreased in relation to its total assets, the Company believes that it is not an investment company subject to the regulations of the Investment Company Act.

If the Company was deemed to be an investment company and could not find another safe harbor or exemption and failed to register as an investment company, the SEC could require the Company to sell its interest in Plug Power, until the value of these securities is further reduced in relation to the Company's total assets. This could result in sales of the Company's securities in quantities of shares at depressed prices and the Company may never realize anticipated benefits from, or may incur losses on, these sales. Further, the Company may be unable to sell some securities due to contractual or legal restrictions or the inability to locate a suitable buyer. Moreover, the Company may incur tax liabilities when selling assets.

Contract Losses

During 2004, MTI Micro entered into a fixed price-cost type completion contract with the U.S. Army. The contract which totaled $250 thousand permitted monthly cost progress payments and called for the delivery of five DMFC power system units. These prototypes required substantial engineering to meet the performance requirements of the customer and at December 31, 2004, MTI Micro accrued $540 thousand for the then anticipated cost needed to complete the project. The contract was completed on November 25, 2005. Additionally, other contracts had forecasted costs in excess of contract values as of December 31, 2004 for which MTI Micro had accrued $17 thousand for the then anticipated cost overruns for the projects. As of December 31, 2005 no amounts are filed as part of this Report:

accrued for anticipated costs to complete open projects.
