1. Basis of Presentation

In the opinion of management of Mechanical Technology Incorporated (the "Company"), the accompanying unaudited condensed consolidated financial statements have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission ("SEC") and contain all adjustments, consisting of normal, recurring adjustments, necessary for a fair statement of results for such periods. The results of operations for the interim periods presented are not necessarily indicative of results for the full year.

Certain information and footnote disclosures normally included in the annual consolidated financial statements prepared in accordance with accounting principles generally accepted in the United States of America ("U.S. GAAP") have been condensed or omitted. These unaudited condensed consolidated financial statements should be read in conjunction with the Company's audited consolidated financial statements and notes thereto included in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2005.

The information presented in the accompanying condensed consolidated balance sheet as of December 31, 2005 has been derived from the Company's audited consolidated financial statements but does not include all disclosures required by U.S. GAAP. All other information has been derived from the Company's unaudited condensed consolidated financial statements for the periods as of and ended September 30, 2006 and 2005.

Liquidity

The Company has incurred significant losses as it continues to fund its subsidiary MTI MicroFuel Cells Inc.'s ("MTI Micro") Direct Methanol Fuel Cell ("DMFC") product development and commercialization programs. The Company expects that losses will continue and 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, Inc. ("MTI Instruments") and MTI Micro, and the availability, or lack thereof, 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 fund research and development costs. The Company anticipates that it will continue incurring losses as it seeks to develop and commercialize its DMFC systems. It expects to continue funding its operations from current cash and cash equivalents, the sale of securities available for sale, government research program funding and the proceeds, if any, from the exercise of the additional investment rights issued to Fletcher International Ltd. ("Fletcher") in connection with the 2004 private placement. The Company may also seek to obtain additional resources through an equity offering.

Fletcher's additional investment rights give it the opportunity, but not the obligation, to purchase (through single or multiple transactions) up to an additional $20 million of our common stock at a per share price of $6.023 (as adjusted from $6.34). Unless adjusted due to certain circumstances, this investment right shall expire on December 31, 2006. Unless our stock price increases, it is unlikely that Fletcher will exercise these investment rights at their present $6.023 price. Regardless of whether Fletcher exercises any or all of their investment rights, the Company anticipates that it will have to attempt to raise additional equity capital to fund its long-term business plan.

During the nine months ended September 30, 2006, the Company sold 903,500 shares of Plug Power Inc.'s ("Plug Power") common stock with proceeds totaling $5,415 thousand and gains totaling $3,810 thousand. These proceeds reflect the Company's previously announced strategy to raise additional capital through the sale of Plug Power stock in order to fund MTI Micro's operations.

2. Significant Accounting Policies

Changes in significant accounting policies since December 31, 2005 are as follows:

The Company reports net (loss) income per basic and diluted common share in accordance with Statement of Financial

7

Accounting Standards ("SFAS") No. 128, Earnings Per Share, which establishes standards for computing and presenting (loss) income per share. Basic earnings per common share are computed by dividing net (loss) income by the weighted average number of common shares outstanding during the reporting period. Diluted (loss) income per share reflects the potential dilution, if any, computed by dividing net (loss) income by the combination of dilutive common share equivalents, comprised of shares issuable under outstanding investment rights, warrants and the Company's share-based compensation plans, and the weighted average number of common shares outstanding during the reporting period. Dilutive common share equivalents include the dilutive effect of in-the-money stock options, which are calculated based on the average share price for each period using the treasury stock method. Under the treasury stock method, the exercise price of a stock option, the amount of compensation cost, if any, for future service that the Company has not yet recognized, and the amount of windfall tax benefits that would be recorded in additional paid-in capital, if any, when the stock option is exercised are assumed to be used to repurchase shares in the current period.

The Company has three stock-based employee compensation plans and its majority-owned subsidiary, MTI Micro, has one stock-based employee compensation plan, all of which are described more fully in Note 15, Stock Based Compensation, in the consolidated financial statements for the year ended December 31, 2005 contained in the Company's 2005 Annual Report on Form 10-K, and in the Company's 2006 Proxy Statement for the Company's 2006 Equity Incentive Plan.

In December 2004, the Financial Accounting Standards Board ("FASB") revised SFAS No. 123 ("FAS 123R"), Share-Based Payment, which establishes accounting for share-based awards exchanged for employee services and requires companies to expense the estimated fair value of these awards over the requisite employee service period. During April 2005, the SEC adopted a rule amending the effective dates for FAS 123R. In accordance with this rule, the accounting provisions of FAS 123R have been adopted by the Company as of January 1, 2006. In March 2005, the SEC issued Staff Accounting Bulletin No. 107 ("SAB 107") to assist filers by simplifying some of the implementation challenges of SFAS 123R. In particular, SAB 107 provides supplemental implementation guidance on FAS 123R, including guidance on valuation methods, classification of compensation expense, inventory capitalization of share-based compensation cost, income tax effects, disclosures in Management's Discussion and Analysis and several other issues. The Company has applied the principles of SAB 107 in conjunction with its adoption of FAS 123R.

Under FAS 123R, share-based compensation cost is measured at the grant date, based on the estimated fair value of the award, and is recognized as expense over the employee's requisite service period. The Company has awards with performance conditions, but no awards with market conditions. The Company adopted the provisions of FAS 123R on January 1, 2006, the first day of the Company's fiscal year, using the modified prospective application, which provides for certain changes to the method for valuing share-based compensation. Under the modified prospective application, prior periods are not revised for comparative purposes. The valuation provisions of FAS 123R apply to new awards and to awards that are outstanding on the effective date and subsequently modified or cancelled. Estimated compensation expense for awards outstanding at the effective date will be recognized over the remaining service period using the compensation cost calculated for pro forma disclosure purposes under the original FASB Statement No. 123, Accounting for Stock-Based Compensation ("FAS 123").

In November  2005, the FASB issued Staff Position No. FAS 123(R)-3, Transition Election Related to Accounting for Tax Effects of Share-Based Payment Awards. The Company has elected to adopt the alternative transition method provided in this FASB Staff Position for calculating the tax effects of share-based compensation pursuant to FAS 123R. This method includes a simplified method to establish the beginning balance of the additional paid-in capital pool related to the tax effects of employee share-based compensation, which is available to absorb tax deficiencies recognized subsequent to the adoption of FAS 123R.

Prior to the adoption of FAS 123R, the Company accounted for stock-based awards to employees and directors using the intrinsic value method in accordance with Accounting Principles Board ("APB") Opinion No. 25, Accounting for Stock Issued to Employees, and related Interpretations as permitted under FAS 123. Under the intrinsic value method, stock-based compensation was only recognized by the Company due to modifications in option provisions, since the exercise price of the Company's and MTI Micro's common stock options granted to employees and directors usually equaled the fair market value of the underlying stock at the date of grant.

Stock-based compensation represents the cost related to stock-based awards granted to employees and directors. The Company measures stock-based compensation cost at grant date, based on the estimated fair value of the award, and recognizes the cost as expense on a straight-line basis (net of estimated forfeitures) over the option's requisite service period.

8

The Company estimates the fair value of stock-based awards using a Black-Scholes valuation model. Stock-based compensation expense is recorded in "Selling, general and administrative expenses" and "Unfunded research and product development expenses" in the Consolidated Statements of Operations based on the employees' respective function.

The Company records deferred tax assets for awards that result in deductions on the Company's income tax returns, unless the Company cannot recognize the deduction (i.e. the Company is in a net operating loss ("NOL") position), based on the amount of compensation cost recognized and the Company's statutory tax rate. Differences between the deferred tax assets recognized for financial reporting purposes and the actual tax deduction reported on the Company's income tax return are recorded in Additional Paid-In Capital (if the tax deduction exceeds the deferred tax asset) or in the Consolidated Statement of Operations (if the deferred tax asset exceeds the tax deduction and no additional paid-in capital exists from previous awards). No tax benefit or expense for stock-based compensation has been recorded during the three and nine months ended September 30, 2006 since the Company remains in a NOL position.

The Company continues to record the fair market value of stock options and warrants granted to non-employees and non-directors in exchange for services in accordance with Emerging Issues Task Force ("EITF") Issue 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 Condensed Consolidated Statements of Operations.

The Company applies the guidance in SAB No. 104, Revenue Recognition, in the evaluation of commercially funded fuel cell research and prototype agreements in order to determine when to properly recognize income. Payments received in connection with commercial research and prototype agreements are deferred and recognized on a straight-line basis over the term of the agreement for service-related payments, and for milestone and prototype delivery payments, if and when achieved, revenue is deferred and recognized on a straight-line basis over the remaining term of the agreement. Under this policy, when revenue qualifies for recognition it will be recorded in the Consolidated Statements of Operations in the line "Funded research and development revenue." The costs associated with research and prototype-producing activities are expensed as incurred. Expenses in an amount equal to revenues recognized are reclassified from "Unfunded research and product development" to "Funded research and product development" in the Consolidated Statements of Operations.

Certain 2005 amounts have been reclassified to conform to the 2006 presentation. The reclassifications have no effect on total revenues, total expenses, net loss or shareholders' equity as previously reported.

The reclassifications impact our Condensed Consolidated Statements of Shareholders' Equity and Comprehensive Income in the following ways:

• Paid-In Capital MTI MicroFuel Cell investment now only includes the minority accounting impact for share-based compensation charges related to MTI Micro.
• Paid-In Capital Share-based compensation now includes the total share-based compensation charges related to MTI Micro, previously included in Paid-In Capital MTI MicroFuel Cell investment; and the effect of both stock option compensation and restricted stock compensation which had previously been presented as separate items.

The reclassifications impact our Condensed Consolidated Statements of Cash Flows in the following way:

• Stock-based compensation now includes both stock based compensation and the minority interest portion of stock-based compensation.

6. Income Taxes

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

11

Income tax (expense) benefit consists of the following:

The valuation allowance at September 30, 2006 and December 31, 2005 was $17,072 thousand and $10,923 thousand, respectively, and represents a full valuation allowance. The valuation allowance reflects the estimate that it is more likely than not that the net deferred tax assets in excess of deferred tax liabilities may not be realized.

7. Shareholders' Equity

The Company has reserved common shares for future issuance as of September 30, 2006 as follows:

8. Loss per Share

The following table sets forth the reconciliation of the numerators and denominators of the basic and diluted per share computations:

At September 30, 2006, options to purchase 5,571,628 shares of the Company's common stock at 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, unvested restricted common shares, and options to purchase 36,668 shares of MTI Micro common stock at prices from $2.39 to $4.66 per share were outstanding but were not included in the computation of earnings per share-assuming dilution because the Company incurred a net loss during this period and their inclusion would be anti-dilutive. Investment rights issued to Fletcher expire on December 31, 2006, subject to extension in certain instances.

13

At September 30, 2005, options to purchase 3,994,925 shares of the Company's common stock at 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, 50,000 unvested restricted common shares, warrants to purchase 28,377 shares of common stock with an exercise price of $10.572 per share, and options to purchase 2,572,682 shares of MTI Micro common stock at prices from $2.39 to $4.66 per share were outstanding but were not included in the computation of earnings per share-assuming dilution because the Company incurred a net loss during this period and their inclusion would have been anti-dilutive. Warrants for the purchase of 28,377 shares expired unexercised on February 5, 2006 and investment rights issued to Fletcher expire on December 31, 2006, subject to extension in certain instances.

9. Gain on 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

11. Segment 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 high performance test and measurement instruments and systems, wafer characterization tools for the semiconductor industry, and computer-based balancing systems for aircraft engines. The Company's principal operations are located in North America.

The accounting policies of the New Energy and Test and Measurement Instrumentation segments are consistent with those described in the summary of significant accounting policies (See Note 1). The Company evaluates performance based on profit or loss from operations before income taxes, accounting changes, other items management does not deem related to reportable segment performance, including interest income and expense. Inter-segment sales and expenses 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 such as 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' non-cash 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 on the sale of these securities and losses related to the embedded derivative for the purchase of Plug Power common stock.

13. Effect of Recent Accounting Pronouncements

In September 2006, the FASB issued SFAS No. 158, Employers' Accounting for Defined Benefit Pension and Other Postretirement Plans, an amendment of FASB Statements No. 87, 88, 106, and 132(R) ("SFAS No. 158"). Among other items, SFAS No. 158 requires recognition of the overfunded or underfunded status of an entity's defined benefit postretirement plan as an asset or liability in the financial statements, requires the measurement of defined benefit postretirement plan assets and obligations as of the end of the employer's fiscal year, and requires recognition of the funded status of defined benefit postretirement plans in other comprehensive income. This Statement is effective for fiscal years ending after December 15, 2006. Since the Company does not maintain any defined benefit or other postretirement plans, the adoption of this Statement is not expected to have a material effect on the Company's Consolidated Financial Statements.

In September 2006, the FASB issued SFAS No. 157, Fair Value Measurements ("SFAS No. 157"). SFAS No. 157 establishes a common definition for fair value to be applied to U.S. GAAP guidance requiring use of fair value, establishes a framework for measuring fair value, and expands disclosure about such fair value measurements. This Statement is effective for fiscal years beginning after November 15, 2007. The Company is currently assessing the impact of SFAS No. 157 on the Company's Consolidated Financial Statements.

In September 2006, the SEC issued SAB 108, Considering the Effects of Prior Year Misstatements when Quantifying Misstatements in Current Year Financial Statements ("SAB 108").  SAB 108 provides guidance on the consideration of the effects of prior year misstatements in quantifying current year misstatements for the purpose of determining whether the current year's financial statements are materially misstated. This Bulletin is effective for fiscal years ending after November 15, 2006. The company will adopt SAB 108 as of January 1, 2007, but it is not expected that the adoption of this Bulletin will have a material impact on the Company's Consolidated Financial Statements.

In July 2006, the FASB issued FASB Staff Position ("FSP") FIN 48, Accounting for Uncertainty in Income Taxes ("FSP FIN 48"), an interpretation of SFAS No. 109, Accounting for Income Taxes. FSP FIN 48 prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. FSP FIN 48 is effective for fiscal years beginning after December 15, 2006; therefore, we will be required to adopt this Interpretation in the first quarter of 2007. We are currently evaluating FSP FIN 48 but have not yet determined the impact, if any; the adoption of this Interpretation will have on the Company's Consolidated Financial Statements.

In March 2006, the FASB issued SFAS No. 156, Accounting for Servicing of Financial Assets-an amendment of FASB Statement No. 140 ("SFAS No. 156") that provides guidance on accounting for separately recognized servicing assets and servicing liabilities. In accordance with the provisions of SFAS No. 156, separately recognized servicing assets and servicing liabilities must be initially measured at fair value, if practicable. Subsequent to initial recognition, the Company may use either the amortization method or the fair value measurement method to account for servicing assets and servicing liabilities within the scope of this Statement. An entity should adopt the Statement as of the beginning of its first fiscal year that begins after June 15, 2006, so the Company will adopt SFAS No. 156 in fiscal year 2007. The adoption of this Statement is not expected to have a material effect on the Company's Consolidated Financial Statements.

In February 2006, the FASB issued SFAS No. 155, Accounting for Certain Hybrid Financial Instruments-an amendment of FASB Statements No. 133 and 140 ("SFAS No. 155") to permit fair value remeasurement for any hybrid financial instrument that contains an embedded derivative that otherwise would require bifurcation in accordance with the provisions of SFAS No. 133, Accounting for Derivative Instruments and Hedging Activities. This Statement is effective for all financial instruments acquired or issued after the beginning of an entity's first fiscal year that begins after June 15, 2006. The Company will adopt SFAS No. 155 in fiscal year 2007. The adoption of this Statement is not expected to have a material effect on the Company's Consolidated Financial Statements.

In April 2006, the FASB issued FSP FIN 46(R)-6, Determining the Variability to Be Considered in Applying FASB Interpretation No. 46(R) ("FSP FIN 46 (R)-6") that will become effective beginning third quarter of 2006. FSP FIN No. 46(R)-6 clarifies that the variability to be considered in applying this Interpretation shall be based on an analysis of the design of variable interest entity. The adoption of this FSP is not expected to have a material effect on the Company's Consolidated Financial Statements.

In the first quarter of 2006, the Company adopted SFAS No. 154, Accounting Changes and Error Corrections-a replacement of APB Opinion No. 20 and FASB Statement No. 3 ("SFAS No. 154"). SFAS No. 154 changed the requirements for the accounting for and reporting of a voluntary change in accounting principle. The adoption of this Statement did not affect the Company's Consolidated Financial Statements in the period of adoption. Its effects on future periods will depend on the nature and significance of any future accounting changes subject to this statement.

17

Beginning January 2006, the Company adopted SFAS No. 151, Inventory Costs-an amendment of ARB No. 43, Chapter 4 ("SFAS No. 151"). SFAS No. 151 requires certain abnormal expenditures to be recognized as expenses in the current period versus being capitalized in inventory. It also requires that the amount of fixed production overhead allocated to inventory be based on the normal capacity of the production facilities. The adoption of this statement did not have a material effect on the Company's Consolidated Financial Statements.

Beginning January 2006, the Company adopted FSP FIN 47, Accounting for Conditional Asset Retirement Obligations, which is an interpretation of SFAS 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 adoption of this statement did not have a material effect on the Company's Consolidated Financial Statements.

Beginning January 2006, the Company adopted SFAS No. 153, Exchanges of Non-monetary Assets ("SFAS No. 153"), an amendment of APB Opinion No. 29. SFAS No. 153 which 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. The adoption of this statement did not affect the Company's Consolidated Financial Statements in the period of adoption. Its effects on future periods will depend on the nature and significance of any future transactions subject to this statement.

14. Commitments and Contingencies

On September 9, 1998, Barbara Lawrence, the Lawrence Group, Inc. ("Lawrence"), and certain other Lawrence-related entities ("Plaintiffs") filed suit in the Bankruptcy Court and the United States District Court for the Northern District of New York which was 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 (five 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 Incorporated 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 (now known as Plug Power, Inc.) 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 FAC 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.

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): $155 remaining in 2006; $563 in 2007, $324 in 2008, and $292 in 2009.

Below is a reconciliation of changes in product warranty liabilities as follows:

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 such agreement.

Under both LANL licenses, license payments made in any year can be applied against royalties due with total annual fees in any year not to exceed $1 million. Also under both LANL licenses, once products are being sold, royalties will be based on 3%, up from 2%, of the first $50 million of net sales, 2%, up from 1%, on net sales in excess of $50 million but less than $100 million and 1%, up from 0.5%, on net sales in excess of $100 million. Any royalties due shall not exceed 2% of net sales.

Under the New York State Energy Research and Development Authority ("NYSERDA") contract, MTI Micro agreed to pay NYSERDA a royalty of 5.0% 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 is reduced to 1.5%. Total royalties are subject to a cap equal to two times the total contract funds paid by NYSERDA to MTI Micro, and may be reduced to reflect any New York State jobs created by MTI Micro.

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 September 30, 2006, the Company's potential minimum obligation to these employees was approximately $1,089 thousand.

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 efforts to meet the performance requirements of the customer and at September 30, 2005, MTI Micro had accrued $11 thousand for the anticipated cost needed to complete the contract. The contract was completed on November 25, 2005. As of September 30, 2006, no amounts are accrued for anticipated losses to complete open contracts.

15. Stock Based Compensation

Stock-based incentive awards are provided to employees and directors under the terms of the Company's 2006 Equity Incentive Plan ("2006 Plan"), the 1999 Employee Stock Incentive Plan ("1999 Plan") and the 1996 Stock Incentive Plan ("1996 Plan") (collectively, the "Plans"). Awards under the Plans have generally included at-the-money options and restricted stock grants. MTI Micro also issued awards under the MTI MicroFuel Cells Inc. 2001 Employee, Director and Consultant Stock Option Plan ("2001 MTI Micro Plan"). During 2005, MTI Micro ceased making grants under the 2001 MTI Micro Plan and determined that it would make no new option awards under this plan in the future.

Stock-based compensation expense for the three and nine months ended September 30, 2006 was generated from stock options and restricted stock grants. Stock options are awards which allow holders to purchase shares of the Company's common stock at a fixed price. Stock options issued to employees generally vest 25% per year beginning one year after grant. Options issued to non-employee members of the MTI Board generally vest upon grant and any MTI Micro options issued to members of the MTI Micro Board, prior to 2005, generally vest 50% per year beginning one year after grant. Certain options granted may be fully or partially exercisable immediately, may vest on other than a four year schedule or vest upon attainment of specific performance criteria. Restricted stock awards generally vest one year after the date of grant; however, certain awards may vest immediately or vest upon attainment of specific performance criteria. Option exercise prices are generally equivalent to, but cannot be less than 85 percent of the closing market value price of the Company's common stock on the date of grant. MTI Micro option exercise prices were based on fair values as determined by the MTI Micro Board. Unexercised options generally terminate ten years after date of grant, except for options issued under the 2006 Plan, which terminate seven years after date of grant.

Prior to January 1, 2006, the Company had 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 FAS 123. 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 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, FAS 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.

Compensation expense related to the intrinsic value of performance-based, unrestricted and restricted stock awards was recorded in "Selling, general and administrative expenses" in the Consolidated Statements of Operations for each of the following periods:

Share-Based Compensation Information under FAS 123R

As discussed in Note 2 "Significant Accounting Policies" effective January 1, 2006, the Company adopted the fair value recognition provisions for stock-based awards granted to employees using the modified prospective application method provided by FAS 123R. Stock-based compensation cost is measured at grant date, based on the fair value of the award, and is recognized as expense over the employee requisite service period.

The Company estimates the fair value of stock options using a Black-Scholes valuation model consistent with the provisions of FAS 123R and SAB 107. Key inputs and assumptions used to estimate the fair value of stock options include the grant price of the award, the expected option term, volatility of the Company's stock, an appropriate risk-free rate, and the Company's dividend yield. Estimates of fair value are not intended to predict actual future events or the value ultimately realized by employees who receive equity awards, and subsequent events are not indicative of the reasonableness of the original estimates of fair value made by the Company.

The fair value of each stock option grant was estimated at the date of grant using a Black-Scholes option pricing model. The following table presents the weighted-average assumptions used for options granted:

*** The risk-free interest rate assumption is based upon observed interest rates appropriate for the expected term of the Company's employee stock options.

**** The dividend yield assumption is based on the Company's history and expectation of future dividend payouts, which may be subject to substantial change in the future.

As share-based compensation expense recognized in the Condensed Consolidated Statement of Operations for the three and nine months ended September 30, 2006 is based on awards ultimately expected to vest, it should be reduced for estimated forfeitures. FAS 123R requires forfeitures to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. Pre-vesting forfeitures were estimated to be approximately 9.5% (annualized) during the nine months of fiscal 2006 based on historical experience. In the Company's pro forma information required under FAS 123 for the periods prior to fiscal 2006, the Company accounted for forfeitures as they occurred. The cumulative effect for the change in forfeitures was immaterial to be presented separately.

Total share-based compensation expense, related to all of the Company's share-based awards, recognized for the three and nine months ended September 30, 2006 was comprised as follows (in thousands):

Total unrecognized compensation costs related to non-vested awards as of September 30, 2006 is $2,691 thousand and is expected to be recognized over a weighted-average vesting period of approximately 1.40 years.

As of January 1, 2006, the adoption of FAS 123R resulted in the elimination of unearned compensation related to restricted stock (contra equity account) against additional paid in capital totaling approximately $80 thousand.
