The holder of Series C Preferred Stock shall have the following conversion rights:

SIGNATURE

EXHIBIT INDEX

The shares of Series C Preferred Stock accrue a cumulative dividend at a rate of 5% per annum of the Stated Liquidation Preference Amount, as defined below. Dividends on the Series C Preferred Stock shall be cumulative, shall accrue, whether or not declared, and be payable quarterly in cash or, at the Company’s option, added to the Stated Liquidation Preference Amount. So long as any shares of Series C Preferred Stock are outstanding, the Company shall not declare, pay or set apart for payment any dividend or make any distribution on any Series B Preferred Stock (other than dividends or distributions paid on the Series B Preferred Stock in common stock in accordance with the terms of the Series B Preferred Stock) or junior stock (other than dividends or distributions on common stock payable solely in shares of common stock), unless at the time of such dividend or distribution the Company shall have paid all accrued and unpaid dividends on the outstanding shares of Series C Preferred Stock. In addition, so long as any shares of Series C Preferred Stock are outstanding, the Company shall not declare, pay or set apart for payment any dividend or make any distribution on any common stock (other than dividends or distributions on common stock payable solely in shares of common stock), unless at the time of such dividend or distribution the Company simultaneously pays a dividend or distribution on each outstanding share of Series C Preferred Stock in an amount equal to the product of (i) the dividend or distribution payable on each share of common stock and (ii) the number of shares of common stock issuable upon conversion of a share of Series C Preferred Stock, calculated on the record date for determination of holders entitled to receive such dividend or distribution.

The holders of Series C Preferred Stock shall be entitled to notice of all meetings of stockholders in accordance with the Company’s bylaws. On any matter presented to the stockholders of the Company for their action or consideration at any meeting of stockholders of the Company (or by written consent of stockholders in lieu of meeting), each holder of outstanding shares of Series C Preferred Stock shall be entitled to cast the number of votes equal to quotient determined by dividing (i) the Series C Original Issue Price ($1,000 per share) of the shares of Series C Preferred Stock held by such holder as of the record date for determining stockholders entitled to vote on such matter by (ii) $1.44 (as adjusted for any stock dividends, combinations, splits and the like with respect to shares of common stock). Except as provided by law or as described below, holders of Series C Preferred Stock shall vote together with the holders of common stock as a single class.

In the event of the liquidation, dissolution or winding up of the affairs of the Company, whether voluntary or involuntary (a “Liquidation”), the holders of shares of the Series C Preferred Stock then outstanding shall be entitled to receive, out of the assets of the Company available for distribution to its stockholders before any payment shall be made to the holders of junior stock by reason of their ownership thereof, an amount per share equal to the greater of:

(i) the Series C Original Issue Price ($1,000 per share) plus any dividends accrued but unpaid thereon (the “Stated Liquidation Preference Amount”); or

(ii) such amount per share as would have been payable had all shares of Series C Preferred Stock been converted into common stock immediately prior to such Liquidation (the amount payable to the holders of Series C Preferred Stock pursuant to clause (i) or (ii) of this sentence is hereinafter referred to as the “Series C Liquidation Amount”).

If upon any such Liquidation, the assets of the Company available for distribution to its stockholders shall be insufficient to pay the holders of shares of Series C Preferred Stock the full amount to which they shall be entitled and the holders of shares of parity stock the full amount to which they shall be entitled pursuant to the terms of such Parity Stock, the holders of shares of Series C Preferred Stock and the holders of shares of parity stock shall share ratably in any distribution of the assets available for distribution in proportion to the respective amounts which would otherwise be payable in respect of the shares held by them upon such distribution if all amounts payable on or with respect to such shares were paid in full. The liquidation payment with respect to each outstanding fractional share of Series C Preferred Stock shall be equal to a ratably proportionate amount of the liquidation payment with respect to each outstanding share of Series C Preferred Stock. All payments shall be in cash, property (valued at its fair market value as determined by an independent appraiser reasonably acceptable to the holders of a majority of the shares of Series C Preferred Stock then outstanding) or a combination thereof; provided, however, that no cash shall be paid to holders of junior stock unless each holder of the outstanding shares of Series C Preferred Stock has been paid in cash the full amount to which such holder shall be entitled. After payment of the full Series C Liquidation Amount, such holders of shares of Series C Preferred Stock will not be entitled to any further participation as such in any distribution of the assets of the Company.

Holder’s Right to Convert.

Company’s Right to Convert.

(i) the Series C Original Issue Price ($1,000 per share) plus any dividends accrued but unpaid thereon (the “Stated Liquidation Preference Amount”); or

Holder’s Right to Convert.

Company’s Right to Convert.

At any time on or after November 8, 2009, if the average closing price of the Company’s common stock for any immediately preceding 180-day period exceeds $7.00 (subject to appropriate adjustment in the event of any stock dividend, stock split, combination or other similar recapitalization with respect to the common stock), the Company will have the right, but not the obligation, to convert each outstanding share of Series C Preferred Stock into a number of fully paid and nonassessable shares of common stock equal to the quotient of (i) the Stated Liquidation Preference Amount divided by (ii) the conversion price in effect as of the Company conversion date.

SATCON TECHNOLOGY CORPORATION

NOTES TO INTERIM CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

Note A. Basis of Presentation

The accompanying unaudited consolidated financial statements include the accounts of SatCon Technology Corporation and its wholly-owned subsidiaries (collectively, the “Company”) as of March 29, 2008 and for the three months then ended and have been prepared by the Company in accordance with accounting principles generally accepted in the United States of America for interim financial reporting and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements. All intercompany accounts and transactions have been eliminated. These unaudited consolidated financial statements, which, in the opinion of management, reflect all adjustments (including normal recurring adjustments) necessary for a fair presentation, should be read in conjunction with the financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2007. Operating results for the three months ended March 29, 2008 are not necessarily indicative of the results that may be expected for any future interim period or for the entire fiscal year.

Note B. Realization of Assets and Liquidity

The Company anticipates that its current cash, along with the availability under its credit facility with Silicon Valley Bank, will be sufficient to fund its operations through at least March 31, 2009. The Company has developed a business plan that envisions a significant increase in revenue and significant reductions in the cost structure and the cash burn rate from the results experienced in the recent past and allows the Company to remain in compliance with the covenants of the credit facility. Although the Company believes it has developed a realistic business plan, there is no assurance that it can achieve these objectives. Accordingly, if the Company is unable to realize its business plan or does not remain in compliance with the covenants of the credit facility, the Company would need to raise additional funds in the near future in order to sustain operations by selling equity or taking other actions to conserve its cash position, which could include selling of certain assets and incurring additional indebtedness. Such actions would likely require the consent of the holders of the Company’s Series C Preferred Stock (the “Investors”), and there can be no assurance that such consent would be given. Furthermore, there can be no assurance that the Company will be able to raise such funds if they are required.

Note C. Significant Accounting Policies and Basis of Consolidation

There have been no material changes from the Significant Accounting Policies and Basis of Presentation previously disclosed in Part II, Item 8, contained within “Notes to Consolidated Financial Statements” of our Annual Report on Form 10-K for the fiscal year ending December 31, 2007.

Basis of Consolidation

The consolidated financial statements include the accounts of SatCon and its wholly-owned subsidiaries (SatCon Applied Technology, Inc., SatCon Electronics, Inc., SatCon Power Systems, Inc. and SatCon Power Systems Canada, Ltd.). All intercompany accounts and transactions have been eliminated in consolidation.

Revenue Recognition

The Company 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, the fee is fixed or determinable, delivery of the product to the customer has occurred and the Company has determined that collection of the fee is probable. Title to the product passes upon shipment of the product, as the products are typically shipped FOB shipping point, except for certain foreign shipments. 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. When appropriate the Company provides for a warranty reserve at the time the product revenue is recognized. If a contract involves the provisions of multiple elements and the elements qualify for separation under EITF 00-21, Revenue Arrangements with Multiple Deliverables, total estimated contact revenue is allocated to each element based on the relative fair value of each element provided. The amount of revenue allocated to each element is limited to the amount that is not

contingent upon the delivery of another element in the future. Revenue is recognized on each element as described above.

The Company performs funded research and development and product development for commercial companies and government agencies under both cost reimbursement and fixed-price contracts. Product development revenue is included in product revenue. Cost reimbursement contracts provide for the reimbursement of allowable costs and, in some situations, the payment of a fee. These contracts may contain incentive clauses providing for increases or decreases in the fees depending on how costs compare with a budget. 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 receives periodic progress payments or payments upon reaching interim milestones. All payments to the Company for work performed on contracts with agencies of the U.S. government are subject to audit and adjustment by the Defense Contract Audit Agency. Adjustments are recognized in the period made. When the current estimates of total contract revenue for commercial product development contracts indicate a loss, a provision for the entire loss on the contract is recorded. As of March 29, 2008 and December 31, 2007, the Company has accrued $1.4 million and $1.3 million, respectively, for anticipated contract losses on commercial contracts. The Company recorded a charge to operations of approximately $0.1 million during the period ended March 29, 2008.

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

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

Unbilled Contract Costs and Fees and Funded Research and Development Costs in Excess of Billings

Unbilled contract costs and fees represent revenue recognized in excess of amounts billed due to contractual provisions or deferred costs that have not been recognized as revenue or billed to the customer.

Cash and Cash Equivalents

Cash and cash equivalents include demand deposits, overnight repurchase agreements with Silicon Valley Bank (the “Bank”) and highly liquid investments with maturities of three months or less when acquired. Cash equivalents are stated at cost, which approximates market value. At March 29, 2008, the Company had approximately $10.6 million invested in a money market account with a national bank. At March 29, 2008 and December 31, 2007, the Company had restricted cash as indicated in the table below. In addition, at March 29, 2008 and December 31, 2007, the Company had overnight repurchase agreements with the Bank of $883,847 and $1,763,502, respectively.

Restricted Cash	March 29, 2008		December 31, 2007
Security deposits	$	34,000	$	34,000
Certificates of deposit	50,000		50,000
Total restricted cash	$	84,000	$	84,000

Accounts Receivable

Accounts receivable are reduced by an allowance for amounts that may become uncollectible in the future. The estimated allowance for uncollectible amounts is based primarily on a specific analysis of accounts in the receivable portfolio and historical write-off experience. While management believes the allowance to be adequate, if the financial condition of our customers were to deteriorate, resulting in impairment of their ability to make payments, additional allowances may be required.

Inventory

Inventory is stated at the lower of cost or market and costs are determined based on the first-in, first-out method of accounting and include material, labor and manufacturing overhead costs. The Company periodically reviews quantities of inventory on hand and compares these amounts to expected usage of each particular product or product line. The Company records, as a charge to cost of sales, any amounts required to reduce the carrying value to net realizable value.

Foreign Currency Translation

The functional currency of the Company’s foreign subsidiary is the local currency. Assets and liabilities of foreign subsidiaries are translated at the rates in effect at the balance sheet date, while stockholders’ equity including the long-term portion of intercompany advances is translated at historical rates. Statements of operations and cash flow amounts are translated at the average rate for the period. Translation adjustments are included as a component of accumulated other comprehensive income (loss). Foreign currency gains and losses arising from transactions that are included as a component of other income (expense) were approximately income of $39,000 of income for the three months ended March 29, 2008 and were $12,000 for the three months ended March 31, 2007. Foreign currency gains (losses) included as a component of cost of goods sold were income of approximately $0.2 million and a loss of approximately $0.1 million for the three months ended March 29, 2008 and March 31, 2007, respectively.

Use of Estimates

The preparation of 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 financial statements and the reported amounts of revenue and expenses during the period reported. Management believes the most significant estimates include the net realizable value of accounts receivable and inventory, the recoverability of long-lived assets and intangible assets, the accrued contract losses on fixed-price contracts, the recoverability of deferred tax assets and the fair value of equity and financial instruments. Actual results could differ from these estimates.

Income Taxes

The Company accounts for income taxes in accordance with SFAS No. 109, Accounting for Income Taxes, which is the asset and liability method for accounting and reporting for income taxes. Under SFAS No. 109, deferred tax assets and deferred tax liabilities are recognized based on temporary differences between the financial reporting and income tax basis of assets and liabilities using statutory rates. In addition, SFAS No. 109 requires a valuation allowance against net deferred tax assets if, based upon the available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized.

In June 2006, the FASB issued Interpretation No. 48, “Accounting for Uncertainty in Income Taxes, an Interpretation of FASB Statement No. 109” (“FIN 48”). FIN 48 requires companies to recognize the tax benefits of uncertain tax positions only where the position is “more likely than not” to be sustained assuming examination by tax authorities. The amount recognized is the amount that represents the largest amount of tax benefit that is greater than 50% likely of being ultimately realized. A liability is recognized for any benefit claimed, or expected to be claimed, in a tax return in excess of the benefit recorded in the financial statements, along with any interest and penalties (if applicable) on that excess. FIN 48 requires a tabular reconciliation of the change in the aggregate unrecognized tax benefits claimed, or expected to be claimed, in tax returns and disclosure relating to the accrued interest and penalties for unrecognized tax benefits. Discussion is also required for those uncertain tax positions where it is reasonably possible that the estimate of the tax benefit will change significantly in the next twelve months.

The Company adopted the provisions of FIN 48 on January 1, 2007. The Company did not recognize any change in the liability for unrecognized tax benefits as a result of the adoption and March 29, 2008.

The tax years 2002 through 2007 remain open to examination by major taxing jurisdictions to which the Company is subject, which are primarily in the United States, as carryforward attributes generated in years past may still be adjusted upon examination by the Internal Revenue Service or state tax authorities if they are or will be used in a future period. The Company is currently not under examination by the Internal Revenue Service or any other jurisdiction for any tax years. The Company did not recognize any interest and penalties associated with unrecognized tax benefits in the accompanying financial statements. The Company would record any such interest and penalties as a component of interest expense. The Company does not expect any material changes to the unrecognized benefits within 12 months of the reporting date.

Accounting for Stock-based Compensation

The Company has several stock-based employee compensation plans. The Company adopted Statement of Financial Accounting Standards No. 123R (“SFAS 123R”) Accounting for Stock-based Compensation, using the modified prospective method, which results in the provisions of SFAS 123R only being applied to the consolidated financial statements on a going-forward basis (that is, the prior period results have not been restated). Under the fair value recognition provisions of SFAS 123R, stock-based compensation cost is measured at the grant date based on the value of the award and is recognized as expense over the service period. Previously, the Company had followed Accounting Principles Board (“APB”) Opinion No. 25, Accounting for Stock Issued to Employees, and related

interpretations, which resulted in the accounting for employee share options at their intrinsic value in the consolidated financial statements.

On March 29, 2005, the SEC issued SAB 107 which expresses the view of the SEC regarding the interaction between SFAS No. 123R and certain SEC rules and regulations concerning the valuation of share-based payment arrangements for public companies. In particular, SAB 107 provides guidance related to share-based payment transactions with non-employees, the transition from nonpublic to public entity status, valuation methods (including assumptions such as expected volatility and expected term), the accounting for certain redeemable financial instrument issues under shares-based payment arrangements, the classification of compensation expense, non-GAAP financial measures, first-time adoption of SFAS No. 123R in an interim period, capitalization of compensation costs related to share-based payment arrangements, the accounting for income tax effects of share-based payment arrangements, the accounting for income tax effects of share-based payment arrangements upon adoption of SFAS No. 123R, the modification of employee share options prior to adoption of SFAS No. 123R, and disclosures in Management’s Discussion and Analysis of Financial Condition and Results of Operations subsequent to adoption of SFAS No. 123R. The Company has accounted for its stock option grants in compliance with SAB 107 and Staff Accounting Bulletin No. 110. Year-End Help for Expensing Employee Stock Option (SAB No. 110).

On November 10, 2005, the Financial Accounting Standards Board (“FASB”) issued FASB Staff Position SFAS 123R-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 the FASB Staff Position for calculating the tax effects (if any) of stock-based compensation expense pursuant to SFAS 123R. The alternative transition method includes simplified methods to establish the beginning balance of the additional paid-in capital pool related to the tax effects of employee stock-based compensation, and to determine the subsequent impact to the additional paid-in capital pool and the consolidated statements of operations and cash flows of the tax effects of employee stock-based compensation awards that are outstanding upon adoption of SFAS 123R.

The Company uses historical volatility as it believes it is more reflective of market conditions and a better indicator of volatility. The Company uses the simplified calculation of expected life described in the SAB No. 107 and SAB No. 110. If the Company determines that another method used to estimate expected volatility was more reasonable than our current methods, or if another method for calculating these input assumptions was prescribed by authoritative guidance, the fair value calculated for share-based awards could change significantly. Higher volatility and longer expected lives result in an increase to share-based compensation determined at the date of grant.

The Company recognized the full impact of its share-based compensation plans in the consolidated financial statements for the three months ended March 29, 2008 and March 31, 2007 under SFAS 123R and did not capitalize any such costs on the consolidated balance sheets, as such costs that qualified for capitalization were not material. The following table presents share-based compensation expense included in the Company’s consolidated statement of operations:

	Three Months Ended
	March 29, 2008		March 31, 2007
Cost of product revenue	$	26,176	$	12,465
Funded research and development and other revenue expense	26,795		21,129
Unfunded research and development and other revenue expenses	12,752		3,794
Selling, general and administrative expenses	80,293		82,309
Share based compensation expense before tax	$	146,016	$	119,697
Income tax benefit	—		—
Net compensation expense	$	146,016	$	119,697

Compensation expense associated with the granting of stock options to employees is being recognized on a straight-line basis over the service period of the option. In instances where the actual compensation expense would be greater than that calculated using the straight-line method, the actual compensation expense is recorded in that period.

The weighted average grant date fair value of options granted during the three months ended March 29, 2008 and March 31, 2007 were $1.66 and $1.30, respectively, per option. The fair value of each stock option is estimated on the date of the grant using the Black-Scholes option-pricing model with the following range of assumptions:

	Three Months Ended
Assumptions:	March 29, 2008	March 31, 2007
Expected life	6.25 years (1)	6.25 years (1)
Expected volatility ranging from	84.71% - 89.47% (2)	87.58% - 89.94% (2)
Dividends	none	none
Risk-free interest rate	2.70% to 3.16% (3)	4.46% to 4.75% (3)
Forfeiture Rate (4)	6.25%	6.25%

(1)	The option life was determined using the simplified method for estimating expected option life, which qualify as “plain-vanilla” options.
(2)	The stock volatility for each grant is measured using the weighted average of historical daily price changes of the Company’s common stock over the most recent period equal to the expected option life of the grant, the historical short term trend of the option and other factors, such as expected changes in volatility arising from planned changes in the Company’s business operations.
(3)	The risk-free interest rate for each grant is equal to the U.S. Treasury yield curve in effect at the time of grant for instruments with a similar expected life.
(4)	The estimated forfeiture rate for each option grant is 6.25%. At the time SFAS 123R was adopted, all outstanding stock options were vested. The Company periodically reviews the estimated forfeiture rate, in light of actual experience.

Concentration of Credit Risk

Financial instruments that subject the Company to concentrations of credit risk principally consist of cash equivalents, trade accounts receivable, unbilled contract costs and deposits in bank accounts. The Company deposits its cash and invests in short-term investments primarily through a national commercial bank. Deposits in excess of amounts insured by the Federal Deposit Insurance Corporation (FDIC) are exposed to loss in the event of nonperformance by the institution. The Company has had cash deposits in excess of the FDIC insurance coverage.

The Company’s trade accounts receivable and unbilled contract costs and fees are primarily from sales to U.S. government agencies and commercial customers. 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.

Research and Development Costs

The Company expenses research and development costs as incurred. Research and development and other revenue expenses include costs incurred in connection with both funded research and development and other revenue arrangements and unfunded research and development activities.

Comprehensive Income (Loss)

Comprehensive income (loss) includes net loss and foreign currency translation adjustments.

Fair Value of Financial Instruments

The Company’s financial instruments consist of cash equivalents, accounts receivable, unbilled contract costs and fees, warrants to purchase shares of common stock, accounts payable, debt instruments, convertible notes, Series B Preferred Stock and Series C Preferred Stock. The estimated fair values of these financial instruments approximate their carrying values at March 29, 2008 and December 31, 2007. The estimated fair values have been determined through information obtained from market sources and management estimates. The Company’s warrant liability is recorded at fair value. See “Fair Value Measurement” section below.

Fair Value Measurements

Effective January 1, 2008, the Company adopted SFAS No. 157, “Fair Value Measurements” (“SFAS 157”). In February 2008, the FASB issued FASB Staff Position No. FAS 157-2, “Effective Date of FASB Statement No. 157,” which provides a one year deferral of the effective date of SFAS 157 for non-financial assets and non-financial liabilities, except those that are recognized or disclosed in the financial statements at fair value at least annually. Therefore, the Company has adopted the provisions of SFAS 157 with respect to its financial assets and liabilities only. SFAS 157 defines fair value, establishes a framework for measuring fair value under generally accepted accounting principles and enhances disclosures about fair value measurements. Fair value is defined under SFAS 157 as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value under SFAS 157 must maximize the use of observable inputs and minimize the use of unobservable inputs. The standard describes a fair value hierarchy based on three levels of inputs, of which the first two are considered observable and the last unobservable, that may be used to measure fair value which are the following:

Level 1 - Quoted prices in active markets for identical assets or liabilities.

Level 2 - Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

Level 3 - Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

The adoption of this statement did not have a material impact on the Company’s consolidated results of operations and financial condition. Level 1 financial assets measured at fair value on a recurring basis consist of money market funds (cash equivalents) of approximately $10.6 million as of March 29, 2008. Level 2 financial assets measured at fair value on a recurring basis consist of long-term investor warrant liabilities of approximately $3.9 million as of March 29, 2008 (see Note J. Convertible Debt Instruments and Warrant Liabilities Valuation – Methodology and Significant Assumptions). The Company has no Level 3 financial assets measured at fair value on a recurring basis as of March 29, 2008. Within the Company’s Level 2 financial assets, which consists of the Warrant As, Warrant Cs and the placement agent warrants, the Warrant As and Warrant Cs are being fair valued utilizing a binomial lattice model and the placement agent warrants are being fair valued using a Black-Scholes option pricing model.

Convertible Debt Instruments and Warrant Liabilities

The Company accounted for its senior secured convertible notes (the “Convertible Notes”), which were paid off on November 7, 2007, and continues to account for the associated warrants in accordance with SFAS 155, Accounting for Certain Hybrid Financial Instruments - an amendment of FASB Statements No. 133 and 140, and SFAS No. 133, Accounting for Derivative Instruments and Hedging Activities, (SFAS 155). The Convertible Notes included features that qualify as embedded derivatives, such as (i) the holders’ conversion option, (ii) the Company’s option to settle the Convertible Notes at the scheduled dates in cash or shares of its common stock, and (iii) premiums and penalties the Company would be liable to pay in the event of default. As permitted under SFAS 155, the Company has irrevocably elected, as of January 1, 2007, to measure the Convertible Notes and embedded derivatives in their entirety at fair value with changes in fair value recognized as either gain or loss.

The Company recorded interest expense under the Convertible Notes based on the greater of (i) 7% or (ii) the six-month LIBOR in effect at the time plus 350 basis points, as well as the amortization of the debt discount, which the Company computed using the effective interest method. The debt discount represented the difference between the Company’s gross proceeds from the sale of the Convertible Notes in July 2006 of $12.0 million and the fair value of the convertible debt upon issuance, after separately valuing the investor warrants, the placement agent warrants and the Convertible Notes on a relative fair value basis. By amortizing the debt discount to interest expense, rather than recognizing it as a change in fair value of the convertible debt instrument and warrants, which is a separate line item in the Company’s statement of operations, the Company believes its interest expense line item more appropriately reflects the cost of the debt associated with the Convertible Notes.

The Company determined the fair values of the Convertible Notes, investor warrants and placement agent warrants using valuation models it considers to be appropriate. The Company’s stock price has the most significant influence on the fair value of its Convertible Notes and related warrants. An increase in the Company’s common stock price would cause the fair values of both the

Convertible Notes and warrants to increase, because the conversion and exercise prices, respectively, of such instruments are fixed at $1.65 and $1.815 per share, respectively, and result in a charge to our statement of operations. A decrease in the Company’s stock price would likewise cause the fair value of the Convertible Notes and the warrants to decrease and result in a credit to our statement of operations. If the price of the Company’s common stock were to decline significantly, however, the decrease in the fair value of the Convertible Notes would be limited by the instrument’s debt characteristics. Under such circumstances, the Company’s estimated cost of capital would become another significant variable affecting the fair value of the Convertible Notes.

Redeemable Convertible Series B Preferred Stock

The Company accounts for its Series B Preferred Stock and associated warrants in accordance with in accordance with EITF 00-27, Application of Issue No. 98-5 to Certain Convertible Instruments, allocating the proceeds received net of transaction costs based on the relative fair value of the redeemable convertible Series B Preferred Stock and the warrants issued to the Investors, and then to any beneficial conversion rights contained in the convertible redeemable preferred securities. The Company determined the initial value of the Series B Preferred Stock and investor warrants using valuation models it considers to be appropriate. The Series B Preferred Stock is classified within the liability section of the Company’s balance sheet. To the extent that the Series B Preferred Stock is subject to a remeasurement event under EITF Topic D-98 or is otherwise modified, the Series B Preferred Stock will be reclassified to temporary equity.

Redeemable Convertible Series C Preferred Stock

The Company accounts for its Convertible Series C Preferred Stock (the “Series C Preferred Stock”), and associated warrants in accordance with in accordance with EITF 00-27, Application of Issue No. 98-5 to Certain Convertible Instruments, allocating the proceeds received net of transaction costs based on the relative fair value of the redeemable convertible Series C Preferred Stock and the warrants issued to the Investors, and then to any beneficial conversion rights contained in the convertible redeemable preferred securities and in accordance with EITF Topic D-98, classifying the Series C Preferred Stock on the balance sheet between the captions for liabilities and shareholder’s equity. The Company determined the initial value of the Series C Preferred Stock and investor warrants using valuation models it considers to be appropriate. The Company is using the effective interest method to accrete the carrying value of the Series C Preferred stock through the earliest possible redemption date (November 8, 2011), at which time the value of the Series C Preferred Stock would be $30.0 million or 120% of its face value.

Note D. Loss per Share

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

	Three Months Ended
	March 29, 2008			March 31, 2007
Net loss	$	(4,343,153	)	$	(3,385,382	)
Basic and diluted:
Common shares outstanding, beginning of period	49,803,979			40,105,073
Weighted average common shares issued during the period	130,940			1,289,587
Weighted average shares outstanding—basic and diluted	49,934,919			41,394,660

Net loss per weighted average share, basic and diluted	$	(0.09	)	$	(0.08	)

As of March 29, 2008 and March 31, 2007, shares of common stock issuable upon the exercise of options and warrants were excluded from the diluted average common shares outstanding, as their effect would have been antidilutive. In addition, shares of common stock issuable upon the conversion of Series B and Series C redeemable convertible preferred stock were excluded from the diluted weighted average common shares outstanding as their effect would also have been anti-dilutive. The table below summarizes the option and warrants and convertible preferred stock that were excluded from the calculation above due to their effect being antidilutive:

	Three Months Ended
	March 29, 2008	March 31, 2007
Common Stock issuable upon the exercise of:
Options	4,066,454	3,759,245
Warrants	26,572,055	11,097,308
Total Options and Warrants excluded	30,638,509	14,856,553
Common stock issuable upon the conversion of senior secured convertible notes, at conversion price of $1.65 per share	—	6,666,667
Common Stock issuable upon the conversion of redeemable convertible Series B Preferred Stock	1,096,774	849,754
Common Stock issuable upon the conversion of redeemable convertible Series C Preferred Stock	24,038,461	—
	25,135,235	7,516,421

The Company reports net loss per basic and diluted common share in accordance with SFAS No. 128, Earnings Per Share, which establishes standards for computing and presenting earnings per share. Basic earnings per share excludes dilution and is computed by dividing income attributable to common stockholders by the weighted average number of common shares outstanding for the period. Diluted earnings per share reflects the potential dilution that could 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 earnings of the Company, except when the effect would be anti-dilutive. The table below details out common stock equivalents which would have been considered dilutive at March 29, 2008 and March 31, 2007 had the Company not been in a loss position:

	# of Underlying Common Shares
	March 29, 2008	March 31, 2007
Employee stock options	1,944,825	269,950
Warrants to purchase common stock	7,742,530	60,235
Series B Convertible Preferred Stock	1,096,774	894,754
Series C Convertible Preferred Stock	24,038,461	—
Common stock issuable upon the conversion of senior secured Convertible Notes, at conversion price of $1.65 per share	—	6,666,667
Total	34,822,590	7,891,606

Note E. Inventory

Inventory components at the end of each period were as follows:

As of March 29, 2008 and December 31, 2007, the Company’s potential obligation to these employees was approximately $500,000. During the year ended December 31, 2006, the Company terminated the employment of an employee that had an employment agreement that provided for severance payments upon termination. The Company recorded a charge to operations of approximately $250,000 related to this severance agreement as selling, general and administrative expense in its results of operations for the year ended December 31, 2006. At March 29, 2008 and March 31, 2007, approximately $0 and $0.1 million was accrued, respectively.

Line of Credit

On February 26, 2008, the Company entered into a Loan and Security Agreement (the “New Loan Agreement”) with the Bank. Under the terms of the New Loan Agreement, the Bank agreed to provide the Company with a credit line up to $10.0 million. The Company’s obligations under the New Loan Agreement are secured by substantially all of the assets of the Company and advances under the New Loan Agreement are limited to 80% of eligible receivables and the lesser of 25% of the value of the Company’s eligible inventory, as defined, or $1.0 million. Interest on outstanding borrowings accrues at a rate per annum equal to the Prime Rate plus one percent (1.0%) per annum, as defined, or the LIBOR Rate plus three and three quarter percent (3.75%) per annum. The New Loan Agreement contains certain financial covenants relating to tangible net worth, as defined, which the Company must satisfy in order to borrow under agreement. In addition the Company agreed to pay to the Bank a collateral monitoring fee of $750 per month and agreed to the following additional terms: (i) $50,000 commitment fee, $25,000 to be paid at signing of the New Loan Agreement and $25,000 to be paid on the one year anniversary of the New Loan Agreement; (ii) an unused line fee in the amount of 0.5% per annum of the average unused portion of the revolving line; and (iii) an early termination fee of 0.5% of the total credit line if the Company terminates the New Loan Agreement prior to 12 months from the New Loan Agreement’s effective date. The New Loan Agreement, if not sooner terminated in accordance with its terms, expires on February 25, 2010. As of March 29, 2008, the Company had $3.0 million outstanding under the New Loan Agreement and the Bank’s prime rate was 6.5%.

Note I. Product Warranties

In its Power Systems divisions the Company provides a warranty to its customers for most of its products sold. In general the Company’s warranties are for one year after the sale of the product, and in five years for photovoltaic inverters. The Company reviews its warranty liability quarterly. Factors taken into consideration when evaluating the Company’s warranty reserve are (i) historical claims for each product, (ii) the development stage of the product, (iii) volume increases, (iv) life of warranty and (v) other factors. To the extent actual experience differs from the Company’s estimates the provision for product warranties will be adjusted in future periods. Such differences may be significant.

Note J. Convertible Debt Instruments and Warrant Liabilities

Features of the Convertible Notes and Warrants

On July 19, 2006, the Company entered into a Securities Purchase Agreement (the “Purchase Agreement”) with the purchasers named therein (the “Purchasers”) in connection with the private placement (the “Private Placement”) of:

· $12,000,000 aggregate principal amount of senior secured convertible notes (the “Convertible Notes”), convertible into shares of the Company’s common stock at a conversion price of $1.65 per share;

· Warrant As to purchase up to an aggregate of 3,636,368 shares of the Company’s common stock at a price of $1.815 per share for a period beginning six months from the date of such warrants and ending on the seventh anniversary of the date of such warrants; and

· Warrant Bs to purchase up to an aggregate of 3,636,368 shares of the Company’s common stock at a price of $1.68 per share for a period of 90 trading days beginning the later of six months from the date of such warrants and the date the Securities and Exchange Commission (the “SEC”) declares effective a shelf registration statement covering the resale of the common stock underlying the securities issued in the Private Placement (the “Registration Statement”); to the extent the Warrant Bs are exercised, the Purchasers were entitled to receive additional warrants (the Warrant Cs), as described below. Because the registration statement was declared effective on September 27, 2006, these warrants were originally exercisable for the 90 trading day period beginning six months from the date of such warrants (i.e. until May 30, 2007). On December 20, 2006 the Warrant Bs were amended to extend the expiration date of the Warrant Bs issued in the Private Placement from May 30, 2007 to August 31, 2007. In addition, this amendment amended the definition of “Excluded Stock” set forth in the Purchase Agreement to enable the Company to issue up to 1.1 million shares of the Company’s common stock in connection with the early termination of the lease for the Company’s facility located in Worcester, Massachusetts, without such shares being subject to the Purchasers’ right of participation set forth in the Purchase Agreement and certain prohibitions set forth in the Convertible Notes and related warrants (as discussed in Note I above, the Company ultimately settled the lease for 850,000 shares). The Warrant Bs were exercised in full on July 17, 2007 for $1.31 per share. See below for a discussion related to the exercise of the Warrant Bs and the issuance of Warrant Cs to the holders as a result of such exercise.

In connection with the Private Placement, the Company also entered into a Security Agreement, dated July 19, 2006, with the Purchasers, pursuant to which the Company granted the Purchasers a security interest in all of its rights, title and interest in, to and under all of the Company’s personal property and other assets, including its ownership interest in the capital stock of its subsidiaries, as security for the prompt payment in full of all amounts due and owing under the Convertible Notes. The following is a summary of the material provisions of the Purchase Agreement, the Notes, the Warrant As, the Warrant Bs and the Warrant Cs.

Securities Purchase Agreement

As noted above, the Purchase Agreement provided for the issuance and sale to the Purchasers of the Convertible Notes, the Warrant As and the Warrant Bs for an aggregate purchase price of $12,000,000. Other significant provisions of the Purchase Agreement include:

· the requirement that the Company pay off all amounts outstanding under its previous credit facility with Silicon Valley Bank;

· for so long as the Convertible Notes were outstanding, the obligation that the Company offer to the Purchasers the opportunity to participate in subsequent securities offerings (up to 50% of such offerings), subject to certain exceptions for, among other things, certain underwritten public offerings and strategic alliances;

· for so long as the Convertible Notes were outstanding, the obligation that the Company not incur any indebtedness that is senior to, or on parity with, the Convertible Notes in right of payment, subject to limited exceptions for purchase money indebtedness and capital lease obligations.

On November 7, 2007, the Convertible Notes were retired by cash redemption.

Additionally, with respect to the common stock underlying the Warrant Cs issued in July 2007 upon exercise of the Warrant Bs, the Company was also obligated to (i) file a registration statement covering the resale of such common stock with the SEC within 30 days following the issuance of the Warrant Cs (which it has satisfied), (ii) use its best efforts to cause such registration statement to be declared effective within 60 days following the issuance of the Warrant Cs (or 90 days in the event of a review of such registration statement by the SEC) (which it has satisfied as such registration statement was declared effective on September 11, 2007) and (iii) use its best efforts to keep such registration statement effective until the earlier of (x) the fifth anniversary of the effective date of the registration statement, (y) the date all of the securities covered by the registration statement have been publicly sold and (z) the date all of the securities covered by the registration statement may be sold without restriction under SEC Rule 144.

Senior Secured Convertible Notes

The Convertible Notes originally had an aggregate principal amount of $12.0 million and were convertible into shares of the Company’s common stock at a conversion price of $1.65, subject to adjustment for stock splits, stock dividends, combinations, distributions of assets or evidence of indebtedness, mergers, consolidations, sales of all or substantially all assets, tender offers, exchange offers, reclassifications or compulsory share exchanges.

The Convertible Notes bore interest at the higher of (i) 7.0% per annum or (ii) the six-month LIBOR plus 3.5% (the “Stated Rate 6-Month LIBOR Condition”). Interest was payable quarterly, beginning on October 31, 2006, and could be paid in cash or, at the Company’s option if certain equity conditions (“Equity Conditions”) were satisfied, in shares of the Company’s common stock. If interest was paid in shares of common stock, the price per share was at a 10% discount to the volume weighted average price for the 20 trading days preceding the payment date. The Equity Conditions included (1) the Company had sufficient authorized shares for issuance, (2) such shares were registered for resale or may be sold without volume restrictions pursuant to Rule 144 under the Securities Act, (3) the common stock was listed or quoted (and was not suspended from trading) on an eligible exchange and such shares were approved for listing upon issuance, (4) the issuance did not violate Section 6(c) of the Convertible Note or the rules and regulations of any trading market, (5) there had been no event of bankruptcy by the Company, (6) the Company was not in default with respect to any material obligation under any documents associated with issuance of the Convertible Notes and Warrants and (7) there had been no public announcement of a pending or proposed change of control that has not been consummated.

Seventy-five percent (75%) of the original principal amount of the Convertible Notes was to be repaid in 18 equal monthly installments ($500,000 per month) beginning on February 28, 2007. Such principal payments could be made in cash or, at the Company’s option if certain equity conditions were satisfied, in shares of common stock. If principal was paid in shares of common stock, the price per share was the lesser of (i) the conversion price or (ii) a 10% discount to the volume weighted average price for the 20 trading days preceding the payment date. At any time following the 24-month anniversary of the issuance of the Convertible Notes, the holders had the right to elect to require the Company to redeem for cash all or any portion of the outstanding principal on the Convertible Notes; provided, however, that on the 60 month anniversary of the issuance of the Convertible Notes, the Company would have been required to redeem any remaining outstanding principal and unpaid interest. Notwithstanding the foregoing, at any time following the one year anniversary of the effective date of the Registration Statement, the Company had the right, under certain circumstances, including satisfaction of the Equity Conditions with respect to the underlying shares, redeem the Convertible Notes for cash equal to 120% of the aggregate outstanding principal amount plus any accrued and unpaid interest.

The Convertible Notes were convertible at the option of the holders into shares of the Company’s common stock at any time at the conversion price. If at any time following the one year anniversary of the effective date of the Registration Statement, the volume weighted average price per share of common stock for any 20 consecutive trading days exceeded 175% of the conversion price, then, if certain conditions were satisfied, including the Equity Conditions, the Company could require the holders of the Convertible Notes to convert all or any part of the outstanding principal into shares of common stock at the conversion price. The Convertible Notes contained certain limitations on optional and mandatory conversion, including that, absent stockholder approval of the transaction, the Company could not issue shares of common stock under the Convertible Notes or the Warrant Bs, in the aggregate, in excess of 19.99% of our outstanding shares on the closing date (or 7,901,276 shares of common stock). On October 19, 2007, the Company received stockholder approval allowing for the issuance of additional shares of the Company’s common stock sufficient to allow for the full conversion of the Company’s outstanding Convertible Notes, as well as the full payment of interest and principal on such notes, all in accordance with the terms of such notes.

The Convertible Notes contained certain covenants and restrictions, including, among others, the following (for so long as any Convertible Notes remained outstanding):

· the Company was required to maintain aggregate cash and cash equivalents equal to the greater of (i) $1,000,000 or (ii) $3,000,000 minus 80% of eligible receivables (as defined in the Convertible Notes);

· if a change of control of the Company occurred, as defined in the Convertible Notes, the holders may elect to require the Company to purchase the Convertible Notes for 115% of the outstanding principal amount plus any accrued and unpaid interest; and

· the Company could not issue any common stock or common stock equivalents at a price per share less than the $1.65 conversion price.

Events of default under the Convertible Notes included, among others, payment defaults, cross-defaults, breaches of any representation, warranty or covenant that was not cured within the proper time periods, failure to perform certain required activities in a timely manner, the Company’s common stock was no longer listed on an eligible market, the effectiveness of the Registration Statement lapsed beyond a specified period and certain bankruptcy-type events involving us or any significant subsidiary. Upon an event of default, the holders could elect to require us to repurchase all or any portion of the outstanding principal amount of the Convertible Notes for a purchase price equal to the greater of (i) 115% of such outstanding principal amount, plus all accrued but unpaid interest or (ii) 115% of the then value of the underlying common stock.

In July 2007, $533,895 of the Convertible Notes and accrued interest were converted into shares of common stock. The Convertible Notes and accrued interest converted at $1.65 per share. The Company issued 318,182 shares of common stock related to the conversion of the principal on the Convertible Notes and 5,391 shares of common stock related to the accrued interest due through the date of conversion as a result of the Convertible Note holders’ conversions.

Warrant As

The Warrant As originally entitled the holders thereof to purchase up to an aggregate of 3,636,368 shares of the Company’s common stock at a price of $1.815 per share for a period beginning six months from the date of such warrants and ending on the seventh anniversary of the date of such warrants. The period prior to six months from the date of the warrants is hereinafter referred to as the “non-exercise period.” The exercise price and the number of shares underlying these warrants are subject to adjustment for stock splits, stock dividends, combinations, distributions of assets or evidence of indebtedness, mergers, consolidations, sales of all or substantially all assets, tender offers, exchange offers, reclassifications or compulsory share exchanges.

If a change of control of the Company occurs, as defined, the holders may elect to require us to purchase the Warrant As for a purchase price equal to the Black-Scholes value of the remaining unexercised portion of each Warrant A.

For so long as any Warrant As remain outstanding, we may not issue any common stock or common stock equivalents at a price per share less than $1.65. In the event of a breach of this provision, the holders may elect to require us to purchase the Warrant As for a purchase price equal to the Black-Scholes value of the remaining unexercised portion of each Warrant A. As a result of the November 8, 2007 and December 20, 2007 preferred stock financing, as described in Note L below, the holders were entitled for a limited period of time (45 days after each issuance) to exercise this right. During the fourth quarter of fiscal 2007, the Company paid approximately $1.4 million to redeem Warrant As representing 1,242,426 shares of common stock. During the first quarter of fiscal 2008, the Company paid approximately $0.4 million to redeem Warrant As representing 303,031 shares of common stock. (See

table below for assumptions used in valuing the warrants redeemed). As of March 29, 2008, 2,090,911 warrant As to purchase common stock were outstanding.

If following the later of (i) the effective date of the Registration Statement and (ii) the six month anniversary of the issuance date, the volume weighted average price per share of our common stock for any 20 consecutive trading days exceeds 200% of the exercise price, then, if certain conditions are satisfied, including the Equity Conditions, we may require the holders of the Warrant As to exercise up to 50% of the unexercised portions of such warrants. If following the 24 month anniversary of the issuance date, the volume weighted average price per share of our common stock for any 20 consecutive trading days exceeds 300% of the exercise price, then, if certain equity conditions are satisfied, we may require the holders of the Warrant As to exercise all or any part of the unexercised portions of such warrants.

Warrant Bs

The Warrant Bs entitled the holders thereof to purchase up to an aggregate of 3,636,368 shares of our common stock at a price of $1.68 per share for a period of 90 trading days beginning the later of six months from the date of such warrants and the date the SEC declares effective the Registration Statement. As noted above, as a result of an amendment, the expiration date of the Warrant Bs was extended to August 31, 2007.

On July 17, 2007, the holders of the Warrant Bs exercised such warrants in full, acquiring 3,636,638 shares of common stock at $1.31 per share. The Company received proceeds of approximately $4.8 million. To entice the holders of the Warrant Bs to exercise such warrants the Company reduced the exercise price from $1.68 to $1.31 per share. As a result of reducing the exercise price the Company recorded a charge to operations in its fiscal third quarter ending September 29, 2007 related to the warrant modification of approximately $0.9 million to change in fair value of the Convertible Notes and warrants on the accompanying statement of operations. Pursuant to the original terms of the Warrant Bs, upon exercise of the Warrant Bs, the warrant holders were entitled to receive additional warrants (“Warrant Cs”) to purchase a number of shares of common stock equal to 50% of the number of shares of common stock purchased upon exercise of the Warrant Bs. As a result of the full exercise of the Warrant Bs, the holders received Warrant Cs to purchase 1,818,187 shares of common stock at an exercise price of $1.815 per share for a period beginning six months from the date of such warrants and ending on the seventh anniversary of the date of such warrants.

Warrant Cs

As discussed above, upon the exercise of the Warrant Bs, the holders were entitled to receive additional warrants (the “Warrant Cs”). The Warrant Cs originally entitled the holders thereof to purchase up to an aggregate of 1,818,187 shares of our common stock at a price of $1.815 per share for a period beginning six months from the date of such warrants and ending on the seventh anniversary of the date of such warrants. The period prior to six months from the date of the warrants is hereinafter referred to as the “non-exercise period.” The exercise price and the number of shares underlying these warrants are subject to adjustment for stock splits, stock dividends, combinations, distributions of assets or evidence of indebtedness, mergers, consolidations, sales of all or substantially all assets, tender offers, exchange offers, reclassifications or compulsory share exchanges.

If a change of control of the Company occurs, as defined, the holders may elect to require us to purchase the Warrant Cs for a purchase price equal to the Black-Scholes value of the remaining unexercised portion of each Warrant C.

For so long as any Warrant Cs remain outstanding, the Company may not issue any common stock or common stock equivalents at a price per share less $1.65. In the event of a breach of this provision, the holders may elect to require the Company to purchase the Warrant Cs for a purchase price equal to the Black-Scholes value of the remaining unexercised portion of each Warrant C. As a result of the November 8, 2007 and December 20, 2007 preferred stock financing, as described in Note L below, the holders were entitled for a limited period of time (45 days after each issuance) exercise this right. During the fourth quarter of fiscal 2007, the Company paid approximately $0.7 million to redeem Warrant Cs representing 621,215 shares of common stock. During the first quarter ended March 29, 2008, the Company paid approximately $0.2 million to redeem Warrant Cs representing 151,516 shares of common stock. (See table below for assumptions used in valuing the warrants redeemed during the three months ended March 29, 2008). As of March 29, 2008, 1,045,456 warrant Cs to purchase common stock were outstanding.

The table below summarizes Black-Scholes option pricing model range of assumptions that were used in valuing the warrants redeemed for both the Warrant As and Warrant Cs during the three month period ended March 29, 2008.

Assumptions:	Warrant As	Warrant Cs

Expected life	5.5 years	6.5 years
Expected volatility ranging from	83.5 %	85.6%
Dividends	none	none
Risk-free interest rate	3.0 %	3.2 %

If following the later of (i) the effective date of the Registration Statement and (ii) the six month anniversary of the issuance date, the volume weighted average price per share of our common stock for any 20 consecutive trading days exceeds 200% of the exercise price, then, if certain conditions are satisfied, including the Equity Conditions, the Company may require the holders of the Warrant Cs to exercise up to 50% of the unexercised portions of such warrants. If following the 24 month anniversary of the issuance date, the volume weighted average price per share of our common stock for any 20 consecutive trading days exceeds 300% of the exercise price, then, if certain equity conditions are satisfied, the Company may require the holders of the Warrant Cs to exercise all or any part of the unexercised portions of such warrants.

Placement Agent Warrants

First Albany Capital (“FAC”) acted as placement agent in connection with the Private Placement. In addition to a cash transaction fee, FAC or its designees were entitled to receive five-year warrants to purchase 218,182 shares of the Company’s common stock at an exercise price of $1.87 per share. These warrants will be callable after the second anniversary of the closing of the Private Placement if the 20-day volume weighted average price per share of the Company’s common stock exceeds 175% of the exercise price. At the direction of FAC, these warrants were issued to First Albany Companies Inc., the parent of FAC.

Accounting for the Convertible Debt Instrument and Warrants

The Company has determined that the Convertible Notes constitute a hybrid instrument that has the characteristics of a debt host contract containing several embedded derivative features that would require bifurcation and separate accounting as a derivative instrument pursuant to the provisions of SFAS 133, Accounting for Derivative Instruments and Hedging Activities (SFAS 133). The Company has identified all of the derivatives associated with the July 19, 2006 financing, and concluded that two of the derivatives cannot be reliably measured nor reliably associated with another derivative that can be reliably measured. As such, the Company has appropriately valued these derivatives as a single hybrid contract together with the Convertible Notes. The contract will be remeasured at each period at the fair value with the changes in fair value recognized in the statement of operations until settlement of the Convertible Notes. As permitted under SFAS 155, the Company has irrevocably elected, as of January 1, 2007, to continue to measure the Convertible Notes and embedded derivatives in their entirety at fair value with changes in fair value recognized as either gain or loss. The Company has determined that this election had no impact on the accounting for the Convertible Notes.

Upon issuance, the Warrant As, Warrant Bs and Warrant Cs, along with the Placement Agent Warrants (together the “Warrants”), did not meet the requirements for equity classification set forth in EITF Issue 00-19, Accounting for Derivative Financial Instruments Indexed to, and Potentially Settled in a Company’s Own Stock, because such warrants (a) must be settled in registered shares, (b) are subject to substantial liquidated damages if the Company is unable to maintain the effectiveness of the resale registration of the shares and (c) there is a cash-out election using a Black-Scholes valuation under various circumstances. Therefore these Warrants are required to be accounted for as freestanding derivative instruments pursuant to the provisions of SFAS 133. Changes in fair value are recognized as either a gain or loss in the statement of operations under the caption “change in fair value of Notes and warrants”. In addition, prior to the exercise by the holders, the Warrant Bs had been classified as a current liability on the balance sheet as they were outstanding for less than one year.

Upon issuance of the Convertible Notes and Warrants, the Company allocated the proceeds received from the Convertible Notes and the Warrants on a relative fair value basis. As a result of such allocation, the Company determined the initial carrying value of the Convertible Notes to be $9.4 million. The Convertible Notes were immediately marked to fair value, resulting in a derivative liability in the amount of $16.3 million. As of March 31, 2007, the Notes have been marked to fair value resulting in a derivative liability of $11.6 million. The net charge Change in Fair Value of Convertible Notes and Warrants for the three months ended March 31, 2007 was $0.5 million. The Convertible Notes were paid off in full in the fourth quarter of 2007.

Upon issuance, the Company allocated $2.7 million of the initial proceeds to the Warrants and immediately marked them to fair value resulting in a derivative liability of $4.9 million and a charge to other expense of $2.2 million. As of December 31, 2006, the Warrants have been marked to fair value resulting in a derivative liability of $2.9 million. As of December 31, 2007, the remaining

The debt discount in the amount of $2.6 million (resulting from the allocation of proceeds) was being amortized to interest expense using the effective interest method over the expected term of the Convertible Notes. During 2007, as a result of the payment in full of the Convertible Notes, the Company amortized the remaining balance resulting in approximately $2.1 million, which is a component of interest expense.

A summary of the changes in the fair value of the Convertible Notes and the Warrants:

	Fair Value of Notes			Fair Value of Warrant Liabilities			Total

(1) Includes a fair value adjustment of $26,440.

(2) The Company satisfied the Convertible Notes in full on November 7, 2007. Pursuant to the terms of the Convertible Notes, the Company was required to pay a premium of 20% of the then outstanding balance of the Convertible Notes.

(3) As a result of the Series C Preferred Stock financing, certain holders of both Warrant As (1,242,426) and Warrant Cs (621,215), through December 31, 2007, exercised their right of redemption, resulting in the Company paying to each redeeming warrant holder the Black-Scholes value of these warrants on the date of notification of redemption. During the three months ended March 29, 2008 holders of both Warrant As (303,031) and Warrant Cs (151,516) exercised their right of redemption, resulting in the Company paying to each redeeming warrant holder the Black-Scholes value of these warrants on the date of notification of redemption.

(4) Amounts included in change in fair value of Convertible Notes and warrants on consolidated statement of operations.

The Company paid the January 31, 2007 interest payment due in cash.

Valuation - Methodology and Significant Assumptions

The valuation of derivative instruments utilizes certain estimates and judgments that affect the fair value of the instruments. Fair values for the Company’s derivatives are estimated by utilizing valuation models that consider current and expected stock prices, volatility, dividends, forward yield curves and discount rates. Such amounts and the recognition of such amounts are subject to significant estimates which may change in the future.

In estimating the fair value of the Convertible Notes and Warrants the following methods and significant input assumptions were applied:

Methods

· A binomial model was utilized to estimate the fair value of the Convertible Notes at December 31, 2006 and March 31, 2007. A binomial model represents finite possible paths of the underlying instruments price over the life of the instrument and is most practical in valuations involving variable inputs or when the option/conversion feature is both exercisable and exercise prior to maturity is favorable (i.e., an American option). The binomial model considers the key features of the Convertible Notes, and is subject to the significant assumptions discussed below. First, a discrete simulation of the Company’s stock price was conducted at each monthly step (node) throughout the expected life of

the instrument. Second, an analysis of all future debt repayments was conducted using an appropriate discount rate, while considering the 10% discount in the event repayments are settled with shares rather than with cash, to estimate the fair value of the debt at each monthly date. The Stated Rate 6-Month LIBOR Condition was estimated by utilizing a 6-month LIBOR forward yield curve based on LIBOR rates and interest rate swaps. Third, an analysis of the higher of the fair value of debt or conversion/redemption value was conducted relative to each node. Fourth, an analysis of the higher of a holding position (i.e., fair value of a future node value discounted using an applicable discount rate) or the fair value result of the second step above was conducted relative to each node until a final fair value of the instrument is concluded at initial node, representing the valuation date. This model requires the following key inputs with respect to the Company and/or instrument:

Input	Dec. 31, 2006			March 31, 2007 (1)
Quoted Stock Price	$	1.14		$	1.30
Conversion Price	$	1.65		$	1.65
Time to Maturity (in years)	4.55			4.30
Stock Volatility	90		%	84		%
Risk-Free Rate	4.71		%	4.54		%
Dividend Rate	0		%	0		%

(1) The Convertible Notes were paid off in full on November 7, 2007.

· A binomial lattice model was utilized to estimate the fair value of Warrant As at December 31, 2006, March 31, 2007, December 31, 2007 and March 29, 2008, as well as the fair value of the Placement Agent Warrants at December 31, 2006 and the Warrant Cs at December 31, 2007 and March 29, 2008. A binomial lattice model was utilized to estimate the fair value of the Warrant Bs at December 31, 2006, March 31, 2007. The binomial model considers the key features of the Warrants, and is subject to the significant assumptions discussed below. First, a discrete simulation of the Company’s stock price was conducted at each node and throughout the expected life of the instrument. Second, an analysis of the higher of a holding position (i.e., fair value of a future node value discounted using an applicable discount rate) or exercise position was conducted relative to each node, which considers the non-exercise period, until a final fair value of the instrument is concluded at the node representing the valuation date. This model requires the following key inputs with respect to the Company and/or instrument:

· A Black-Scholes option pricing model was utilized to estimate the fair value of Placement Agent Warrants at March 31, 2007, December 31, 2007 and March 29, 2008. A change in method from the binomial to Black-Scholes was warranted because the warrants’ non-exercise period ended prior to the valuation date and all required inputs were fixed. This model requires the following key inputs with respect to the Company and/or instrument:

Input	March 31, 2007			Dec. 31, 2007			March 29, 2008
Quoted Stock Price	$	1.30		$	1.65		$	1.84

Dividend Rate	0		%	0		%	0		%
Non-Exercise Period	N/A			N/A			N/A

Significant Assumptions:

· Penalties upon an event of default and liquidated damages are fully reflected in the fair values of the Convertible Notes. These features are typical protective features in similar convertible instruments and accordingly are fully considered in our market based inputs for volatility, interest rates, and appropriate discount rates;

· The Convertible Notes’ Equity Conditions are assumed to have been met throughout the life of the instrument;

· The Company expects to settle the required future principal redemptions and interest payments, under the terms of the Convertible Notes, with shares of common stock rather than with cash;

· Stock volatility was estimated by annualizing the daily volatility of the Company’s stock price during the historical period preceding the respective valuation dates and measured over a period corresponding to the remaining life of the instruments. Historic stock prices were used to estimate volatility as the Company did not have traded options as of the valuation dates;

· The volume weighted average price for the 20 trading days preceding a payment date is reasonably approximated by the average of the simulated stock price at each respective node of the binomial model;

· Based on the Company’s historical operations and management expectations for the near future, the Company’s stock was assumed to be a non-dividend-paying stock;

· The quoted market price of the Company’s stock was utilized in the valuations because SFAS 133 requires the use of quoted market prices without considerations of blockage discounts. Because the stock is thinly traded, the quoted market price may not reflect the market value of a large block of stock; and

· The quoted market price of the Company’s stock as of measurement dates and expected future stock prices were assumed to reflect the effect of dilution upon conversion of the instruments to shares of common stock.

Note K. Redeemable Convertible Series B and Series C Preferred Stock

Series B Convertible Preferred Stock

340 and 345 shares of Series B Preferred Stock were outstanding as of March 29, 2008 and March 31, 2007, respectively. As of March 29, 2008 and March 31, 2007, the Series B Preferred Stock was convertible into 1,096,774 and 849,754 shares of Common Stock, respectively. As of March 29, 2008 and March 31, 2007, the conversion price of the Series B Preferred Stock was $1.55 and $2.03, respectively, per share.

As a result of the issuance of shares of common stock in lieu of cash for the principal payments due on the Convertible Notes (see Note J. Convertible Debt Instruments and Warrant Liabilities), the issuance of common stock to the landlord, the Company recorded the following non-cash charges as interest expense in its Statement of Operations during the three months ended March 31, 2007 and adjusted the conversion price on the Series B Preferred Stock as follows:

Date	Type of Payment	Conversion/ Exercise Price		Adjusted Conversion/ Exercise Price (1)		Interest Expense
1/3/07	Lease settlement issuing 850,000 shares	$	2.06	$	2.04	$	16,912
2/28/07	Principal payment issuing 445,899 shares	$	2.04	$	2.03	$	8,498

(1) After the adjustments made to the conversion price during the year ended December 31, 2007, the 340 outstanding shares of Series B Preferred Stock are convertible into 1,096,774 shares of common stock at a conversion price of $1.55 per share.

There were no adjustments to the conversion price of the Series B Preferred Stock during the quarter ended March 29, 2008.

Series C Convertible Preferred Stock

On November 8, 2007, the Company entered into a Stock and Warrant Purchase agreement with Rockport Capital Partners II, L.P. and NGP Energy Technology Partners, L.P. (the “Investors”). Under this purchase agreement, the Investors agreed to purchase in a private placement up to 25,000 shares of the Company’s newly created Series C convertible preferred stock (the “Series C Preferred Stock”) and warrants to purchase up to 19,711,539 shares of common stock, for an aggregate gross purchase price of $25.0 million. Each share of Series C Preferred Stock initially converts into common stock at a price equal to $1.04 per share, subject to adjustment.

This private placement occurred in two closings. The first closing occurred on November 8, 2007. At the first closing, the Company issued 10,000 shares of Series C Preferred Stock at $1,000 per share for an aggregate gross purchase price of $10.0 million. These shares are currently convertible into 9,615,384 shares of common stock. The Company also issued warrants to purchase an aggregate of 15,262,072 shares of common stock. These warrants are exercisable for a seven-year term and had an initial exercise price of $1.44 per share and may not be exercised until May 8, 2008. As a result of stockholder approval of the second closing and related matters on December 20, 2007, as described below, the exercise price of these warrants was reduced to $1.25 per share. The Company considered this a cancellation and reissuance of new warrants and accounted for the change in the fair value of the warrants in the allocation of net proceeds associated with the second closing and treated it as a deemed dividend to the Series C Preferred Stock holders. (See Accounting for the Series C Preferred Stock below).

At the second closing, which occurred on December 20, 2007, following stockholder approval, the Company issued 15,000 shares of Series C Preferred Stock for an aggregate gross purchase price of $15.0 million, of which $10.0 million was paid through the cancellation of the promissory notes previously issued to the Investors on November 7, 2007. These shares are currently convertible into 14,423,076 shares of common stock. At this closing, the Company also issued warrants to purchase an aggregate of 4,449,467 shares of common stock at an exercise price of $1.25 per share. These warrants are exercisable for a seven-year term and are exercisable immediately.

In the purchase agreement, the Company also agreed to issue the Investors additional warrants in the event that the holders of certain existing warrants (none of whom are affiliated with the Investors) exercise those warrants in the future. Upon such exercises, the Company will issue to the Investors additional warrants to purchase common stock equal to one-half of the number of shares of common stock issued upon exercise of these existing warrants. The exercise price of these warrants will be $1.25 per share. As of March 29, 2008, if all of these existing warrants are exercised, the Company would need to issue warrants to purchase an additional 3,430,258 shares of common stock to the Investors.

Dividends on Series C Preferred Stock

The Company is not permitted, without the affirmative vote or written consent of the holders of at least 67% of the outstanding Series C Preferred Stock (50% of the outstanding Series C Preferred Stock with respect to items (4), (5) and (8) below), directly or indirectly, to take any of the following actions or agree to take any of the following actions:

(1) authorize, create or issue any shares of preferred stock or other equity securities ranking senior to or on a parity with the Series C Preferred Stock;

(2) increase or decrease the total number of authorized shares of Series C Preferred Stock;

(3) amend or modify the Company’s certificate of incorporation (including the Certificate of Designation governing the Series C Preferred Stock) or bylaws that would adversely affect the rights, preferences, powers and privileges of the Series C Preferred Stock;

(4) repurchase or redeem any shares of Series B Preferred Stock (except pursuant to the existing terms of the Series B Preferred Stock) or any equity securities ranking junior to the Series C Preferred Stock, subject to certain exceptions;

(5) effect any distribution or declare, pay or set aside any dividend with respect to any equity securities ranking junior to the Series C Preferred Stock;

(6) incur any form of indebtedness for borrowed money in excess of $5,000,000 in the aggregate (other than indebtedness existing at November 8, 2007);

(7) effect a liquidation, consummate a reorganization event or dispose, transfer or license any material assets, technology or intellectual property, other than non-exclusive licenses in connection with sales of the Company’s products in the ordinary course of business;

(8) consummate any transaction that results in the transfer or issuance of securities, or options, warrants or other rights to receive securities of a subsidiary or any other transaction following which a subsidiary no longer remains wholly-owned by the Company or pursuant to which any third party has a right to purchase securities of a subsidiary;

(9) change the size of the Company’s board of directors;

(10) encumber or grant a security interest in all or substantially all or a material part of the Company’s assets except to secure indebtedness permitted above that is approved by the Company’s board of directors;

(11) acquire a material amount of assets of another entity, through a merger, purchase of assets or purchase of capital stock or otherwise; or

(12) enter into any agreement to do or cause to be done any of the foregoing.

At any time the holder of any such shares of Series C Preferred Stock may, at such holder’s option, elect to convert all or any portion of the shares of Series C Preferred Stock held by such person into a number of fully paid and nonassessable shares of common stock equal to the quotient of (i) the Stated Liquidation Preference Amount of the shares of Series C Preferred Stock being converted divided by (ii) the conversion price then in effect as of the date of the delivery by such holder of its notice of election to convert. The initial conversion price of the Series C Preferred Stock is $1.04 per share. The Series C Preferred Stock will receive weighted average anti-dilution protection in the event of a dilutive issuance in accordance with a formula set forth in the Certificate

of Designation, subject to certain exceptions.

Redemption

At any time and from time to time on or after November 8, 2011 the holders of at least 66.7% of the then outstanding shares of Series C Preferred Stock may elect to have all or any portion of the outstanding shares of Series C Preferred Stock redeemed. The Company shall effect the redemption on a redemption date by paying cash or, at the Company’s election, shares of common stock (valued in the manner described below).

If such redemption shall be for cash, the Company shall effect the redemption, out of funds legally available therefor, by paying in cash in exchange for each share of Series C Preferred Stock to be redeemed a sum equal to the product of (i) 1.2 multiplied by (ii) the Stated Liquidation Preference Amount.

If such redemption shall be for shares of common stock, the Company shall effect the redemption by issuing, in exchange for each share of Series C Preferred Stock to be redeemed, that number of shares of common stock equal to (A) the product of (i) 1.4 multiplied by (ii) the Stated Liquidation Preference Amount divided by (B) the fair market value of the common stock, based on a 10 day volume weighted average, as of the redemption date.

Accounting for the Series C Preferred Stock

The Company accounted for the transaction in accordance with EITF 00-27, Application of Issue No. 98-5 to Certain Convertible Instruments, allocating the proceeds received net of transaction costs based on the relative fair value of the redeemable convertible Series C Preferred Stock and the warrants issued to the Investors, and then to any beneficial conversion rights contained in the convertible redeemable preferred securities as follows:

Security	Face Value		Fair Value		Allocation of Proceeds, Net of Transaction Costs		Beneficial Conversion Feature		Initial Carrying Value
Redeemable convertible Series C Preferred Stock	$	25,000,000	$	18,193,950	$	12,991,097	$	11,762,887	$	1,228,210
Warrants	—		$	18,352,179	$	10,092,623	—		—

The re-pricing of the exercise price of the Tranche I warrants from $1.44 to $1.25, as described above, was treated as a cancellation of the original warrants issued on November 8, 2007 and a re-issuance of new warrants on December 20, 2007. The difference in fair value of the warrant was included in the allocation of net proceeds associated with the second closing of the Series C Preferred Stock on December 20, 2007. The Company treated this as a deemed dividend on the Series C Preferred Stock. The Company recorded a discount, including the re-pricing and beneficial conversion feature of $11,762,887 and recorded a deemed dividend of $11,947,881 to the holders of the Series C Preferred Stock, which included the initial allocation of the discount of $11,762,887 and $184,994 related to the accretion of the Series C Preferred Stock to its redemption value through the date that holders of the Series C Preferred Stock may first exercise their redemption right. The Company is using the effective interest method to accrete the carrying value of the Series C Preferred stock through the earliest possible redemption date (November 8, 2011), at which time the value of the Series C Preferred Stock would be $30.0 million or 120% of its face value. The components of the carrying value of the Series C Preferred Stock from inception on November 8, 2007, the year ended December 31, 2007 and the three months ended March 29, 2008, is as follows:

	Total
Initial carrying value November 8, 2007	$	1,228,210
Deemed dividend through December 31, 2007	$	11,762,887
Accretion of original issue discount to redemption value through December 31, 2007	$	184,994
Total	$	13,176,091
Dividend through December 31, 2007 (1)	$	100,000
Balance at December 31, 2007	$	13,276,091
Accretion of original issue discount to redemption value for the three months ended March 29, 2008	637,991
Dividend for the three months ending March 29, 2008 (1)	303,962
Balance at March 29, 2008	$	14,218,044

(1) The Company recorded $0.3 million and $0.1 million during the three months ended March 29, 2008 and the year ended December 31, 2007, respectively, as a dividend on the Series C Preferred Stock. Dividends on the Series C Preferred Stock accrue at a rate of 5% and are payable quarterly. The Company elected to add the dividend to the liquidation preference of the Series C Preferred Stock and it was recorded as a dividend to the holders of the Series C Preferred Stock.

In valuing the warrants associated with the Series C Preferred Stock the Company used the Black-Scholes option pricing model with the following range of assumptions:

	November 8, 2007	December 20, 2007
Assumptions:
Expected life	4.0 years	5.2 years
Expected volatility	70%	70%
Dividends	none	none
Risk-free interest rate	3.64%	3.48%

The Company has designated the warrants as equity instruments in accordance with EITF 00-19.

preparation of these consolidated financial statements requires management to make significant estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements and the reported revenue and expenses during the reporting periods. On an ongoing basis, management evaluates its estimates and judgments, including those related to revenue recognition, receivable reserves, inventory reserves, goodwill and intangible assets, contract losses and income taxes. 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 value 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. There have been no material changes from the “Critical Accounting Policies and Significant Judgments and Estimates” previously disclosed in Part II, Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations” of our Annual Report on Form 10-K for the fiscal year ending December 31, 2007.

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

We recognize revenue from product sales in accordance with SEC Staff Accounting Bulletin No. 104, Revenue Recognition. Product revenue is recognized when there is persuasive evidence of an arrangement, the fee is fixed or determinable, delivery of the product to the customer has occurred and we have determined that collection of the fee is probable. Title to the product passes upon shipment of the product, as the products are typically shipped FOB shipping point, except for certain foreign shipments. If the product requires installation to be performed by us, 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 we can objectively and reliably demonstrate that the criteria specified in the acceptance provisions are satisfied. When appropriate, we provide for a warranty reserve at the time the product revenue is recognized. If a contract involves the provisions of multiple elements and the elements qualify for separation under EITF 00-21 Revenue Arrangements with Multiple Deliverables, total estimated contact revenue is allocated to each element based on the relative fair value of each element provided. The amount of revenue allocated to each element is limited to the amount that is not contingent upon the delivery of another element in the future. Revenue is recognized on each element as described above.

We perform funded research and development and product development for commercial companies and government agencies under both cost reimbursement and fixed-price contracts. Cost reimbursement contracts provide for the reimbursement of allowable costs and, in some situations, the payment of a fee. These contracts may contain incentive clauses providing for increases or decreases in the fee depending on how costs compare with a budget. 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 services are performed. In each type of contract, we receive periodic progress payments or payment upon reaching interim milestones and retain the rights to the intellectual property developed in government contracts. All payments to us for work performed on contracts with agencies of the U.S. government are subject to audit and adjustment by the Defense Contract Audit Agency. Adjustments are recognized in the period made. The Defense Contract Audit Agency has agreed-upon the final indirect cost rates for the fiscal year ended September 30, 2003. When the current estimates of total contract revenue and contract costs for product development contracts indicate a loss, a provision for the entire loss on the contract is recorded. As of March 29, 2008 and December 31, 2007, we have accrued approximately $1.4 million and $1.3 million, respectively, for anticipated contract losses on commercial contracts.

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

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

Unbilled contract costs and fees represent revenue recognized in excess of amounts billed due to contractual provisions or deferred costs that have not yet been recognized as revenue or billed to the customer.

Accounts Receivable

resulting in impairment of their ability to make payments, additional allowances may be required.

Inventory

We value our inventory at the lower of actual cost to purchase and/or manufacture the inventory or the current estimated market value of the inventory. We periodically review inventory quantities on hand and record a provision for excess and/or obsolete inventory based primarily on our estimated forecast of product demand, as well as based on historical usage. Due to the custom and specific nature of certain of our products, 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. In addition, our industry is characterized by rapid technological change, frequent new product development, and rapid product obsolescence that could result in an increase in the amount of obsolete 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 or technological developments could have a significant impact on the value of our inventory and our reported operating results.

Convertible Debt Instruments and Warrant Liabilities

We accounted for our senior secured convertible notes (the “Convertible Notes”), which were paid off on November 7, 2007, and associated warrants in accordance with SFAS No. 133, Accounting for Derivative Instruments and Hedging Activities. The Convertible Notes included features that qualify as embedded derivatives, such as (i) the holders’ conversion option, (ii) our option to settle the Convertible Notes at the scheduled dates in cash or shares of our common stock and (iii) premiums and penalties we would be liable to pay in the event of default. As permitted under SFAS 155, we irrevocably elected, as of January 1, 2007, to measure the Convertible Notes in their entirety at fair value with changes in fair value recognized as either gain or loss. Subsequent to the pay-off of the Convertible Notes, we will continue to account for the associated warrants as described above.

We recorded interest expense under the Convertible Notes based on the greater of (i) 7% or (ii) the six-month LIBOR, in effect at the time plus 350 basis points, as well as the amortization of the debt discount, which we computed using the effective interest method. The debt discount represents the difference between our gross proceeds of $12.0 million and the fair value of the convertible debt upon issuance, after separately valuing the investor warrants, the placement agent warrants and the Convertible Notes on a relative fair value basis. By amortizing the debt discount to interest expense, rather than recognizing it as a change in fair value of the Convertible debt instrument and warrants, which is a separate line item in our statement of operations, we believe our interest expense line item more appropriately reflects the cost of the debt associated with the Convertible Notes.

We determined the fair values of the Convertible Notes, investor warrants and placement agent warrants using valuation models we consider to be appropriate. Our stock price has the most significant influence on the fair value of the Convertible Notes and related warrants. An increase in our common stock price would cause the fair values of both the Convertible Notes and warrants to increase, because the conversion and exercise prices, respectively, of such instruments are fixed at $1.65 and $1.815 per share, respectively, and result in a charge to our statement of operations. A decrease in our stock price would likewise cause the fair value of the Convertible Notes and the warrants to decrease and result in a credit to our statement of operations. If the price of our common stock were to decline significantly, however, the decrease in the fair value of the Convertible Notes would be limited by the instrument’s debt characteristics. Under such circumstances, our estimated cost of capital would become another significant variable affecting the fair value of the Convertible Notes.

Income Taxes

The preparation of our consolidated financial statements requires us to estimate our income taxes in each of the jurisdictions in which we operate, including those outside the United States, which may be subject to certain risks that ordinarily would not be expected in the United States. The income tax accounting process involves estimating our actual current exposure together with assessing temporary differences resulting from differing treatment of items, such as deferred revenue, for tax and accounting purposes. These differences result in the recognition of deferred tax assets and liabilities. We must then record a valuation allowance to reduce our deferred tax assets to the amount that is more likely than not to be realized.

Significant management judgment is required in determining our provision for income taxes, our deferred tax assets and liabilities and any valuation allowance recorded against deferred tax assets. We have recorded a full valuation allowance against our deferred tax assets of approximately $51.9 million as of December 31, 2007, due to uncertainties related to our ability to utilize these assets. The valuation allowance is based on our estimates of taxable income by jurisdiction in which we operate and the period over which our deferred tax assets will be recoverable. In the event that actual 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.

Results of Operations

Three Months Ended March 29, 2008 (“2008”) Compared to Three Months Ended March 31, 2007 (“2007”)

Product Revenue. Total product revenue for 2008 increased approximately $7.2 million or 110% from $6.5 million in 2007 to $13.7 million in 2008.

Division	2008		2007		$ Change		% Change
Power Systems, US	$	928	$	735	$	193	26	%
Power Systems, Canada	10,176		3,604		6,572		182	%
Electronics	2,598		2,194		404		18	%
Total product revenue	$	13,702	$	6,533	$	7,169	110	%

The increase of $6.6 million in revenue in 2008 in the Power Systems, Canada division, as compared to 2007, was largely due to an increase in Solar Converter line revenue of approximately $4.1 million, an increase of approximately $1.6 million in Fuel Cell product line revenue, and to a lesser extent, an increase of approximately $0.1 million in Industrial Power Supplies revenue, $0.1 million in Frequency Converters revenue and $0.6 million in other revenue.

The increase of $0.2 million in revenue in 2008 in the Power Systems US division, as compared to 2007, was largely due an increase Motor product line revenues of approximately $0.9 million.

Revenues in the Electronics division increased approximately $0.4 million in 2008, as compared to 2007. The increase was primarily due to an increase in commercial customer revenue of approximately $0.5 million, offset by a decrease in sales of approximately $0.2 million to government customers as compared to 2007.

Funded research and development and other revenue. Funded research and development and other revenue decreased from $1.8 million in 2007 to $1.2 million in 2008. Approximately $0.8 million of the decrease was due to a government contract being completed in 2007 and an approximately $0.2 million decrease in other commercial contract revenue over the same period in 2007. The decrease was offset by an increase of approximately $0.4 million in Department of Defense contract revenue over the same period in 2007.

Cost of product revenue. Cost of product revenue increased $6.3 million, or 99%, from $6.4 million in 2007 to $12.6 million in 2008.

Total cost of product revenue	$	12,648	$	6,370	$	6,278		-99	%

The increase was primarily attributable the mix of products sold during the period and higher revenues compared to fiscal 2007 in all of our divisions.

Gross Margin. Gross margins on product revenue increased from 2% for 2007 to 7% in 2008. Gross margin by division is broken out below.

Power Systems, US	9	%	-39	%
Power Systems, Canada	7	%	-3	%
Electronics	11	%	25	%
Total gross margin %	8	%	2	%

In our Power Systems, US division, the increase in gross margin by 48% is a direct result of the increase in revenue for 2008 as compared to 2007, and lower overall overhead costs as compared to 2007. Our Power Systems, Canada division had an increase in gross margin of 10% partially due to a change in the product mix and increased revenues. The decrease in gross margin of 14% in our Electronics division is primarily due to mix of products sold resulting higher material and labor costs during the period as compared to 2007.

Funded research and development and other revenue expenses. Funded research and development and other revenue expenses decreased by approximately $0.4 million, or 35%, from $1.4 million in 2007 to $1.0 million in 2008. The gross margin on funded research and other revenue decreased from 24% in 2007 to 14% in 2008. This decrease is a due to the decrease in revenue for 2008 and the mix of business in 2008 as compared to 2007.

Unfunded research and development expenses. We expended approximately $1.0 million on unfunded research and development in 2008 compared with approximately $0.7 million spent in 2007. The spending in 2008 and 2007 was related primarily for the development of new products and technologies in our Power Systems, Canada division.

Selling, general and administrative expenses. Selling, general and administrative expenses increased by approximately $0.3 million, or 9%, from $2.8 million in 2007 to $3.1 million in 2008. Approximately $0.3 million of the increase was associated with higher sales and marketing costs in our Power Systems, Canada division in 2008.

Amortization of intangibles. Amortization of intangibles remained flat at $0.1 million.

Change in fair value of Convertible Notes and warrants. The change in fair value of the Convertible Notes and warrants for 2008 was a charge of approximately $0.5 million. The change in fair value of the Convertible Notes and warrants for 2007 was a credit of approximately $0.2 million.

Other Income (expense). Other income was approximately $54,000 for 2008 compared to other expense of approximately $40,000 for 2007. Other income for 2008 consists primarily of approximately $70,000 related to order cancellation charges during the period off set by fees paid related to consulting services for the valuation of our Convertible Note financing transaction as well as other expenses not related to ongoing operations. Other expense for 2007 consists primarily of consulting services related to the valuation of our Convertible Note financing transaction as well as other expenses not related to ongoing operations.

Interest income. Interest income remained flat at $0.1 million and is directly attributable to our cash on hand.

Interest expense. Interest expense decreased $0.6 million in 2008 to $47,000 as compared to $0.6 million in 2007. Interest expense for 2008 includes approximately $30,000 of non-cash dividends on our Series B Preferred Stock, which we have elected to pay in shares of our common stock and interest on outstanding amounts under our line of credit during the period. Interest expense in fiscal 2007 includes approximately $260,000 of non-cash interest associated with payments on our Notes, approximately $300,000 in amortization of the debt discount on our July 2006 Senior Secured Notes, and approximately $30,000 of non-cash dividends on our Series B Preferred Stock, which we have elected to pay in shares of our common stock.

Deferred Revenue. Deferred revenue was approximately $12.3 million at March 29, 2008 as compared to $8.1 million at December 31, 2007, an increase of $4.2 million. We record deferred revenue (i) when a customer pays in advance or (ii) when provisions for revenue recognition on items shipped have not been achieved or the items have not yet been received by the customer due to shipping terms such as FOB destination.

Currently deferred revenue is composed of approximately $2.3 million for two Rotary UPS units that have been shipped to the customer site and are awaiting customer installation and final on-site acceptance testing, $1.8 million in our Applied Technology division related to the second stage of a Flywheel Generation Set order for which the customer has paid a significant portion of the sales price in advance of delivery (these units were delivered in April 2008 and will be included in our Applied Technology’s revenue for that quarter when reported) and approximately $2.1 million of the $7.7 million in our Power Systems, Canada division related to pre-payments received on orders currently being manufactured, $4.0 million related to a project with the Navy for which all units have been delivered during the fist quarter of 2008 and are awaiting commissioning and on-site acceptance by the Navy and approximately $2.1 million related to extended warranty contracts on products sold. For items that have shipped and are awaiting recognition of revenue their costs are included in our finished goods inventory value at the end of the period.

Liquidity and Capital Resources

As of March 29, 2008, we had approximately $11.8 million of cash, of which approximately $0.1 million was restricted.

Based upon our current working capital position, current operating plans and expected business conditions, we believe that our current cash, as well as the availability from our new line of credit with Silicon Valley Bank, will be adequate to fund our operations through March 31, 2009. In the long run, we expect to fund our working capital needs and other commitments primarily through our operating cash flow, which we expect to improve as we improve our operating margins and grow our business. We also expect to rely on our credit facility to fund a portion of our capital needs and other commitments.

Our funding plans for our working capital needs and other commitments may be adversely impacted if we fail to realize our underlying assumed levels of revenues and expenses or if we fail to remain in compliance with the covenants of our bank line. If either of those events occur, we may need to raise additional funds in order to sustain operations by selling equity or taking other actions to conserve our cash position, which could include selling of certain assets, delaying capital expenditures and incurring additional indebtedness, subject to the restrictions in the preferred stock financing with the investors and in the new credit facility with Silicon Valley Bank. Such actions would likely require the consent of the investors and/or Silicon Valley Bank, and there can be no assurance that such consents would be given. Furthermore, there can be no assurance that we will be able to raise such funds if they are required

If additional funds are raised in the future through the issuance of equity or convertible debt securities, the percentage ownership of our stockholders will be reduced and our stockholders will experience additional dilution. The terms of additional funding may also limit our operating and financial flexibility. There can be no assurance that additional financing of any kind will be available to us on terms acceptable to us, or at all. Failure to obtain future funding when needed or on acceptable terms would materially, adversely affect our results of operations.

As a result of the preferred stock financing, the holders of certain outstanding warrants had the right for a limited period of time (45 days after each closing) to seek redemption of those warrants at their Black-Scholes value. During the first quarter of fiscal 2008, we paid approximately $0.6 million to redeem Warrant As representing 303,031 shares of common stock and Warrant Cs representing 151,516 shares of common stock. Following these redemptions, as of March 29, 2008, Warrant As representing 2,090,911 shares of common stock and Warrant Cs representing 1,045,456 shares of common stock remain outstanding. The redemption periods under these warrants associated with our preferred stock financing have expired. If these redemption rights are triggered again in the future as a result of subsequent equity issuances below $1.65 per share, our liquidity position would be adversely impacted.

We have incurred significant costs to develop our technologies and products. These costs have exceeded total revenue. As a result, we have incurred losses in each of the past five years. As of March 29, 2008, we had an accumulated deficit of approximately $180.2 million. Since inception, we have financed our operations and met our capital expenditure requirements primarily through the sale of private equity securities and convertible debt, public security offerings, borrowings under our previous line of credit and capital equipment leases.

As of March 29, 2008, our cash and cash equivalents were $11.8 million, including restricted cash and cash equivalents of $0.1 million; this represents a decrease in our cash and cash equivalents of approximately $0.9 million from the $12.7 million on hand at December 31, 2007. Cash used in operating activities for the three months ended March 29, 2008 was $3.2 million as compared to $2.5 million for the three months ended March 31, 2007. Cash used in operating activities during the three months ended March 29, 2008 was primarily attributable to the net loss of approximately $3.4 million offset by non-cash items such as the change in the fair value of our warrants, depreciation and amortization, deferred revenue, non-cash compensation and consulting expense, non-cash interest expense and decreases in working capital.

Cash used in investing activities during the three months ended March 29, 2008 was $0.2 million as compared to $0.2 million for the three months ended March 31, 2007. Cash used in investing activities during these periods was a result of capital expenditures during each of the respective periods.

Cash provided by financing activities for the three months ended March 29, 2008 was approximately $2.6 million as compared to cash provided by financing activities of $0.1 million for the three months ended March 31, 2007. Net cash provided by financing activities during 2008 primarily related to borrowings under our line of credit of $3.0 million and approximately $0.1 million from the exercise employee stock options and offset in part by approximately $0.6 million paid to warrant holders exercising their redemption right during the period and payments on our capital lease obligations. Net cash used in financing activities during 2007 primarily related to payments on our capital lease obligations.

Payments Due Under Contractual Obligations

We lease equipment and office space under non-cancelable capital and operating leases. The future minimum rental payments as of March 29, 2008 under the capital and operating leases with non-cancelable terms are included in the table below:

Calendar Years Ending December 31,	Capital Leases		Operating Leases

2008	$	8,630	$	1,017,623
2009	11,573		$	1,058,346

2012	11,573		$	—
Thereafter	1,931		$	—

Total	$	56,853	$	2,759,174

Effects of Inflation

We believe that inflation and changing prices over the past three years have not had a significant impact on our net revenue or on our income from continuing operations.
