Accumulated unrealized gains related to securities available for sale are as follows:

The Company's effective income tax benefit rate from operations differed from the Federal statutory rate as follows:

Income tax benefit (expense) consists of the following:

The valuation allowance at March 31, 2005 and December 31, 2004 was $1.836 million. It is anticipated that a full valuation allowance will be required by the end of 2005. The provision for this quarter has been adjusted to reflect the projected annual effective rate including the anticipated impact of a full valuation allowance. The valuation allowance reflects the estimate that it was more likely than not that certain net operating losses may be unavailable to offset future taxable income.

Changes in common shares issued are as follows:

Changes in treasury stock shares are as follows:

The Company has reserved common shares for future issuance as of March 31, 2005 as follows:

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 the Company's common stock, on one or more occasions, at a price of $6.023

15

8. Shareholders' Equity (Continued)

(adjusted from $6.34) per share at any time prior to December 31, 2006. 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 time table agreed to, 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 obligated to file one or more registration statements covering the resale of such shares. Fletcher also has the right to purchase up to 2,700,000 shares of Plug Power common stock owned by us, potentially at a discount to the market price of such shares at the time of purchase.

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, 2005. The Company failed to meet its contractual obligation with Fletcher to have such registration statement declared effective by March 22, 2005 and therefore under the terms of the Fletcher agreement we were required to issue additional shares of common stock to Fletcher and the exercise

price for the Fletcher additional investment rights has been reduced to $6.023 per share. We are required to issue a number of shares of common stock that will result in Fletcher having effectively made its December 2004 investment at a price per share that is 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 we 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.

The additional investment rights provide Fletcher with 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 (adjusted from $6.34), which date and price may be extended and adjusted, respectively, in the event that we have not satisfied our contractual obligations with respect to the registration for resale of common stock issued or issuable to Fletcher.

The table below illustrates the number of shares Fletcher would receive upon exercise of its $20 million additional investment right at a price per share equal to $6.023 (adjusted from $6.34) (such exercise price is subject to adjustment as described below under "Adjustment Provisions"). Further, the Company's 2004 private placement agreement with Fletcher provides that the maximum number of shares we could potentially issue to Fletcher is 8,330,411 shares.

The Company has placed 2,700,000 shares of Plug Power common stock in escrow that are available for purchase by Fletcher in certain instances. Fletcher may, 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 have the right to have 250,000 of such shares released from escrow to us, on a monthly basis, in the event that on any day during such month, the prevailing price of our common stock exceeds $6.343 (which price may have been adjusted to reflect stock splits, recombinations, stock dividends or the like).

16

7. Shareholders' Equity (Continued)

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 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. As used herein, a prevailing price is the average of the daily volume-weighted average price per share of common stock during the sixty-business-day period ending three days prior to the date Fletcher elects to exercise such right, provided however that the price may not exceed the average of the daily volume-weighted average prices for any ten business days within such sixty-business day period. Each of the above referenced per share exercise prices for the additional investment rights is subject to adjustment as described below under "Adjustment Provisions."

As a result of this exercise price calculation, we may be required to sell shares of Plug Power at a discount to prices we would otherwise obtain in sales at market prices. The table below illustrates such potential discounts

based on assumed decreases in our stock price from $5.00 (which, for the purposes of this illustration, serves as an approximation of the price of our common stock), and an assumed price of Plug Power common stock at the time of exercise.

• a restatement of our financial results,
• a change in control of our company,
• a future issuance of our capital stock at a price less than $7.048 as it relates to the initial $10 million investment and $6.34 as it relates to all additional investments, or
• our failure to maintain the effectiveness of the registration statement relating to shares of our common stock that Fletcher owns or may acquire, as well as our failure to satisfy the other requirements relating to registration.
  

In the event we restate any portion of our financial statements prior to January 29, 2005, or prior to the first anniversary of the closing of any additional investment, as the case may be, the exercise price for the additional investment rights may be adjusted to equal the average price (as defined) of our common stock sixty days after we restate our financial statements if the average price of the Company's common stock sixty days after a restatement is five percent lower than the average price three days before the restatement (a "Qualifying Restatement"). In addition, with respect to any investments made prior to the time of the restatement, Fletcher would receive additional shares of common stock such that all such investments will have been effectively made at such adjusted exercise price.

17

8. Shareholders' Equity (Continued)

The following table illustrates the number of additional shares of common stock Fletcher would receive without any additional payment on its part in the event that the average price of the Company's common stock sixty days after a restatement (as defined) is $5.00 per share and $4.00 per share.

In response to comments received from the SEC staff of the Division of Corporation Finance, the Company previously amended its current Annual Report on Form 10-K for the year ended December 31, 2004 and its prior

Annual Reports on Form 10-K for the years ended December 31, 2003 and December 31, 2002 to supplement the Company's financial statements with additional financial statements of SatCon Technology Corporation and Plug Power, which were all previously publicly available, and to include certain summary financial information for both companies in the relevant notes to the Company's financial statements. In the Company's opinion, the above do not constitute restatements for purposes of its agreement with Fletcher.

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

As described above, we failed to satisfy the registration requirement for the 1,261,829 shares of common stock purchased by Fletcher on December 22, 2004 until April 21, 2005.

18

The 2004 private placement also provides Fletcher certain other rights including, but not limited to, indemnification rights with respect to (1) breaches of representations, warranties and covenants contained in the agreements with Fletcher, and (2) misstatements in or omissions from the prospectus and the registration statement relating to shares of our common stock that Fletcher owns or may acquire.

8. Loss Per Share

The following is the reconciliation of the numerators and denominators of the basic and diluted loss per share computations:

For the three months ended March 31, 2005, options to purchase 3,754,250 shares of common stock at exercise prices ranging from $0.54 to $20.92 per share, additional investment rights to purchase approximately 3,320,604 shares ($20 million divided by $6.023 per share) of common stock with an exercise price of $6.023 per share and warrants to purchase 28,377 shares of common stock with an exercise price of $10.572 per share were outstanding but were not included in the computations of Loss per Share-assuming dilution because the Company incurred losses during this period and inclusion would be anti-dilutive.

For the three months ended March 31, 2004, options to purchase 2,825,650 shares of common stock at exercise prices ranging from $0.54 to $20.92 per share, additional investment rights to purchase approximately 3,688,990 shares ($26,000,000 divided by $7.048 per share) of common stock with an exercise price of $7.048 per share and warrants to purchase 28,377 shares of common stock with an exercise price of $10.572 per share were outstanding but were not included in the computations of Loss per Share-assuming dilution because the Company incurred losses during this period and inclusion would be anti-dilutive.

9. Sale of Securities Available for Sale

The Company sold shares of the following securities and recognized gains and proceeds as follows:

10. Cash Flows - Supplemental Information

The Company operates in two business segments, New Energy and Test and Measurement Instrumentation. The New Energy segment is focused on commercializing DMFCs. The Test and Measurement Instrumentation segment designs, manufactures, markets and services computer-based balancing systems for aircraft engines, high-performance test and measurement instruments and systems, and wafer characterization tools for the semiconductor industry. The Company's principal operations are located in North America.

The accounting policies of the New Energy and Test and Measurement Instrumentation segments are the same as those described in the summary of significant accounting policies in the Company's consolidated financial statements (See Note 1) for the year ended December 31, 2004. The Company evaluates performance based on profit or loss from operations before income taxes, accounting changes, items management does not deem relevant to segment performance, and interest income and expense. Inter-segment sales are not significant.

Summarized financial information concerning the Company's reportable segments is shown in the following table. The "Other" column includes corporate related items and items like income taxes or unusual

items, which are not allocated to reportable segments. The "Reconciling Items" column includes minority interests in

a consolidated subsidiary. In addition, segments' noncash items include any depreciation and amortization in reported profit or loss. The New Energy segment figures include the Company's micro fuel cell operations, equity securities of Plug Power, gains (losses) on the sale of these securities, (losses) gains related to the embedded derivative for the purchase of Plug Power common stock and warrants to purchase SatCon common stock.

20

The Company purchases materials from E.I. du Pont de Nemours and Company ("DuPont"), a shareholder in MTI Micro, such purchases totaled $45 thousand and $123 thousand for the three months ended March 31, 2005 and 2004, respectively. The Company has a liability to DuPont for materials purchases totaling $9 thousand as of March 31, 2005 and a net receivable totaling $2 thousand as of December 31, 2004. This liability is included in the financial statement line "Accrued liabilities - related parties." The net receivable is included in the financial statement line "Other receivables - related parties."

13. Effect of Recent Accounting Pronouncements

In November 2004, the Financial Accounting Standards Board ("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 is in the process of evaluating the impact of this standard on its consolidated financial statements.

21

13. Effect of Recent Accounting Pronouncements (Continued)

In December 2004, the FASB issued SFAS No. 123 (Revised 2004) Share-Based Payment ("SFAS No. 123R"). 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. SFAS No. 123R will require the Company to expense SBP awards with compensation cost for SBP transactions measured at fair value. The FASB originally stated a preference for a lattice model because it believed that a lattice model more fully captures the unique characteristics of employee stock options in the estimate of fair value, as compared to the Black-Scholes model which the Company currently uses for its footnote disclosure. The FASB decided to remove its explicit preference for a lattice model and not require a single valuation methodology. SFAS No. 123R requires the Company to adopt the new accounting provisions beginning in its first quarter of 2006. The Company has not yet determined the impact of applying the various provisions of SFAS No. 123R. The unvested value of share awards to be amortized into the operating statement is approximately $5.7 million as of December 31, 2004.

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 beginning in our second quarter of fiscal 2006. The Company is in the process of evaluating the impact of this standard on its consolidated financial statements.

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 Incorporated, 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 common 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 negotiation 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, the 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 the outcome 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.

13. Commitments and Contingencies (Continued)

The Company and its subsidiaries lease four 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): $519 remaining in 2005; $532 in 2006, $327 in 2007, $316 in 2008, $289 in 2009, and $0 thereafter.

A reconciliation of changes in product warranty liabilities is as follows:

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.

23

14. Commitments and Contingencies (Continued)

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 SEC requesting that it 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 with Gillette, the Company has agreed to indemnify Gillette against any losses arising out 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.

During 2004, MTI Micro entered into a fixed price-cost type completion contract with the U.S. Army. The contract which totals $250 thousand permits monthly cost progress payments and calls for the delivery of five DMFC power system units. These prototypes require substantial engineering to meet the performance requirements of the customer. At the end of 2004, MTI Micro forecasted that the contract would be completed during 2005 and accrued $ 540 thousand for the then anticipated cost needed to be incurred to complete the project. The expected overrun has increased to $1.036 million and the accrued contract overrun remains at $540 thousand as of March 31, 2005. Although MTI Micro believes that it will complete this contract to the satisfaction of the customer, it is possible that MTI Micro will not be successful. Through monthly reports, MTI Micro updates the customer on accomplishments, technical issues, financial status, forecast to complete and anticipated solutions.

Additionally, other contracts have forecasted costs in excess of contract values as of March 31, 2005 and December 31, 2004. As of the end of 2004, MTI Micro accrued $17 thousand for the anticipated cost overruns for the projects and the accrued contract overrun remains at $17 thousand as of March 31, 2005.

15. Issuance of Stock by Subsidiary

MTI Micro was formed on March 26, 2001. As of March 31, 2005, the Company owns approximately 89% of MTI Micro's outstanding common stock.

The increase in the Company's paid-in-capital related to MTI MicroFuel Cell investment of $46 thousand for the period ended March 31, 2005, represents the changes in the Company's equity investment in MTI Micro, which resulted from third-party stock transactions in MTI Micro.

This Item 2 contains forward-looking statements that involve risks and uncertainties, which may cause the Company's actual results, performance or achievements to be materially different from those expressed or implied by such forward-looking statements. See "Statement Concerning Forward-Looking Statements" on page 32.

The Company is primarily engaged in the development and commercialization of Mobion^TM cord-free advanced portable power systems, through its subsidiary MTI MicroFuel Cells Inc. ("MTI Micro"), and in the design, manufacture, and sale of high-performance test and measurement instruments and systems through its subsidiary MTI Instruments, Inc. ("MTI Instruments"). MTI also co-founded and retains a minority interest in Plug Power Inc. ("Plug Power") (Nasdaq: PLUG), a designer and developer of on-site energy systems based on proton exchange membrane fuel cells.

MTI Micro designs and develops Mobion^TM fuel cell systems for portable power applications. A micro fuel cell is a portable power source that converts chemical energy into useable electrical energy. MTI Micro is developing a micro fuel cell that uses methanol, a common alcohol, as its fuel. The Company believes direct methanol fuel cell ("DMFC") systems could potentially have an energy density of five to ten times that of Li-Ion batteries. The Company believes that, when commercialized, DMFC systems should be able to power a wireless electronic device for longer periods of time than Li-Ion batteries without recharging/refueling. In addition, Mobion^TM fuel cell systems may be instantly refueled eliminating the need for a power outlet or a lengthy recharge.

MTI Micro's fuel cell 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 initial product is a power source for hand held RFID tag readers. The first Mobion^TM fuel cell systems were delivered at the end of 2004 in low volumes to a single consumer.

MTI Micro has also developed prototype DMFC systems for military customers, including the RF Communications Division of Harris Corporation ("Harris"), a supplier of military communication devices. Pursuant to the Harris agreements, MTI Micro delivered prototypes during the first and second quarters of 2003 and the second quarter of 2004.

MTI Instruments has three product groups: aviation, general gaging and semiconductor. These product groups provide: electronic, computerized general gaging instruments for position, displacement and vibration applications; and semiconductor products for wafer characterization of semi-insulating and semi-conducting wafers and vibration analysis systems for aircraft engines. MTI Instruments' strategy is to continue to enhance and expand its product offerings with the goal of increasing market share and profitability. MTI Instruments' largest customers include the U.S. Air Force and industry leaders in the computer, electronic, semiconductor, automotive, aerospace, aircraft and bioengineering fields.

MTI Instruments' engine balancing and vibration analysis system primarily serves the aviation industry, both in the commercial and military sectors.  These systems perform a number of vibration analysis and engine balancing functions typically for large turbofan engines on the flight-line and in test cells.  In addition, MTI Instruments' engine balancing and vibration analysis system has recently been used for the first time in an industrial turbo machinery application.

MTI Instruments' general gaging product line employs three sensing technologies - capacitance, fiber optics and laser triangulation - to measure displacement, position, thickness, vibration and other dimensional measurement applications.  The advantages of each technology are generally related to the requirements of specific applications, which typically transcend the capabilities of conventional measuring techniques.  End-users cover a broad range of industrial markets, as well as research labs, universities and the government agencies.

MTI Instruments' semiconductor tools compete in the wafer metrology segment of the semiconductor equipment market. Product models include manual units, semi-automated units and fully automated systems that measure thickness, total thickness variation, bow, warp, site and global flatness. These metrology and inspection tools

25

cover a broad range of applications both on the front-end and back-end of the manufacturing process. End-users of these tools include both wafer manufacturers (foundries) and device (chip) manufacturers.

From inception through March 31, 2005, the Company has incurred net losses of $72.7 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, gains on sales of securities available for sale and the operating results of MTI Instruments and MTI Micro.

The Company's discussion and analysis of its financial condition and results of operations are 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 Company's 2004 annual 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, revenues 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 judgments 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. Our critical accounting estimates were discussed with our Audit Committee.

The following is management's discussion and analysis of certain significant factors, which have affected the Company's results of operations for the three months ended March 31, 2005 compared to the three months ended March 31, 2004.

Product Revenue. Product revenue for 2005 decreased in comparison to the same period in 2004 by $.176 million, or 11.1%, to $1.403 million. This decrease is the result of decreases in sales to semiconductor customers of $.142 million and aviation customers of $.135 million offset by increases in sales to general gaging customers of $.101 million. The decrease in semiconductor sales reflects the shipment of one manual gage during the first quarter of 2005 as compared to five manual gages and one semi-automated unit for the same period in 2004. The decrease in sales to aviation customers includes a $.182 million decrease related to the timing of shipments under the Retrofit Air Force contract due to fewer portable balancing systems, change amplifiers and accessory kits being sent by the U.S. Air Force for upgrade in 2005 than in 2004. A total of 22 units were upgraded in 2005 compared to 30 in 2004. This reduction in upgrade business was partially offset by the shipment of five new accessory kits under a priority contract from the U.S. Air Force for $.059 million. The increase in general instrument sales is primarily due to a $.095 million increase in capacitance product sales to a distributor.

Information regarding government contracts included in product revenue is as follows:

(Dollars in thousands, except contract values)

26

Funded Research and Development Revenue. Funded research and development revenue for 2005 decreased in comparison to the same period in 2004 by $.064 million to $.324 million, a 16.5% decrease. The decrease is the result of the National Institute of Standards and Technology ("NIST") contract's completion in 2004 when it contributed $.388 million in revenue. This revenue decline was offset in 2005 by $.151 million in revenues from the DOE contract, $.112 million from the NYSERDA contract, $.025 million from the Marines and $.036 million from the CSMP NIST subcontract.

Information regarding government contracts included in funded research and development revenue is as follows:
