NOTE A — DESCRIPTION OF BUSINESS Organization The Company includes Orion Energy Systems, Inc., a Wisconsin corporation, and all of its consolidated subsidiaries. The Company is a developer, manufacturer and seller of lighting and energy management systems and a seller and integrator of renewable energy technologies to commercial and industrial businesses, predominantly in North America. See Note I “Segment Reporting” of these financial statements for further discussion of our reportable segments. The Company’s corporate offices and manufacturing operations are located in Manitowoc, Wisconsin and an operations facility occupied by Orion Engineered Systems is located in Plymouth, Wisconsin.

NOTE B — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Principles of Consolidation The condensed consolidated financial statements include the accounts of Orion Energy Systems, Inc. and its wholly-owned subsidiaries. All significant intercompany transactions and balances have been eliminated in consolidation. Reclassifications Where appropriate, certain reclassifications have been made to prior years’ financial statements to conform to the current year presentation. Basis of Presentation The accompanying unaudited condensed consolidated financial statements of the Company have been prepared in accordance with accounting principles generally accepted in the United States (GAAP) for interim financial information and with the rules and regulations of the Securities and Exchange Commission. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments, consisting of normal recurring adjustments, considered necessary for a fair presentation have been included. Interim results are not necessarily indicative of results that may be expected for the year ending March 31, 2013 or other interim periods. The condensed consolidated balance sheet at March 31, 2012 has been derived from the audited consolidated financial statements at that date but does not include all of the information required by GAAP for complete financial statements. The accompanying unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and footnotes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended March 31, 2012 filed with the Securities and Exchange Commission on June 14, 2012. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and reported amounts of revenues and expenses during that reporting period. Areas that require the use of significant management estimates include revenue recognition, inventory obsolescence and bad debt reserves, accruals for warranty expenses, income taxes and certain equity transactions. Accordingly, actual results could differ from those estimates. The Company’s valuation allowance for deferred tax assets is based upon estimates of future taxable income. Cash and Cash Equivalents The Company considers all highly liquid, short-term investments with original maturities of three months or less to be cash equivalents.   Short-Term Investments The amortized cost and fair value of short-term investments, with gross unrealized gains and losses, as of March 31, 2012 and September 30, 2012 were as follows (in thousands):   <table cellspacing="0"

short-term nature of the investment (level 1 inputs). Fair Value of Financial Instruments The Company’s financial instruments consist of cash and cash equivalents, short-term investments, accounts receivable, accounts payable, accrued liabilities and long-term debt. The carrying amounts of the Company’s financial instruments approximate their respective fair values due to the relatively short-term nature of these instruments, or in the case of long-term, because of the interest rates currently available to the Company for similar obligations. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. GAAP describes a fair value hierarchy based on the following three levels of inputs, of which the first two are considered observable and the last unobservable, that may be used to measure fair value: Level 1 — Valuations are based on unadjusted quoted prices in active markets for identical assets or liabilities. Level 2 — Valuations are based on quoted prices for similar assets or liabilities in active markets, or quoted prices in markets that are not active for which significant inputs are observable, either directly or indirectly. Level 3 — Valuations are based on prices or valuation techniques that require inputs that are both unobservable and significant to the overall fair value measurement. Inputs reflect management's best estimate of what market participants would use in valuing the asset or liability at the measurement date. Accounts Receivable The majority of the Company’s accounts receivable are due from companies in the commercial, industrial and agricultural industries, as well as wholesalers. Credit is extended based on an evaluation of a customer’s financial condition. Generally, collateral is not required for end users; however, the payment of certain trade accounts receivable from wholesalers is secured by irrevocable standby letters of credit and/or guarantees. Accounts receivable are generally due within 30-60 days. Accounts receivable are stated at the amount the Company expects to collect from outstanding balances. The Company provides for probable uncollectible amounts through a charge to earnings and a credit to an allowance for doubtful accounts based on its assessment of the current status of individual accounts. Balances that are still outstanding after the Company has used reasonable collection efforts are written off through a charge to the allowance for doubtful accounts and a credit to accounts receivable.   Financing Receivables The Company considers its lease balances included in consolidated current and long-term accounts receivable from its Orion Throughput Agreement, or OTA, sales-type leases to be financing receivables. Additional disclosures on the credit quality of the Company’s financing receivables are as follows: Aging Analysis as of September 30, 2012 (in thousands):   <table cellspacing="0" cellpadding="0" width="100%" border="0" style="border-collapse:collapse; text-align: left" align="center">  <tr> <td width="81%"> </td> <td valign="bottom" width="1%"> </td> <td> </td> <td> </td> <td> </td> <td valign="bottom" width="1%"> </td> <td> </td> <td> </td> <td> </td> <td valign="bottom" width="1%"> </td> <td> </td> <td> </td> <td> </td> <td valign="bottom" width="1%"> </td> <td> </td> <td> </td> <td> </td> <td valign="bottom" width="1%"> </td> <td> </td> <td> </td> <td> </td> </tr> <tr> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom" colspan="2" align="center" style="border-bottom:1px solid #000000">Not past due</td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom" colspan="2" nowrap="nowrap" align="center" style="border-bottom:1px solid #000000">1-90 days past due</td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom" colspan="2" align="center" style="border-bottom:1px solid #000000">Greater than 90 days past due</td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom" colspan="2" align="center" style="border-bottom:1px solid #000000">Total past due</td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom" colspan="2" nowrap="nowrap" align="center" style="border-bottom:1px solid #000000">Total sales-type leases</td> <td valign="bottom"> </td> </tr>   <tr bgcolor="#cceeff"> <td valign="top"> Lease balances included in consolidated accounts receivable -

A considerable amount of judgment is required in order to make this assessment, including a detailed analysis of the aging of the lease receivables and the current credit worthiness of the Company’s customers and an analysis of historical bad debts and other adjustments. If there is a deterioration of a major customer’s credit worthiness or if actual defaults are higher than historical experience, the estimate of the recoverability of amounts due could be adversely affected. The Company reviews in detail the allowance for doubtful accounts on a quarterly basis and adjusts the allowance estimate to reflect actual portfolio performance and any changes in future portfolio performance expectations. The Company believes that there is no impairment of the receivables for the sales-type leases. The Company incurred $59,000 and $0 of write-offs or credit losses against its OTA sales-type lease receivable balances in fiscal 2012 and for the six months ended September 30, 2012, respectively. Inventories Inventories consist of raw materials and components, such as ballasts, metal sheet and coil stock and molded parts; work in process inventories, such as frames and reflectors; and finished goods, including completed fixtures and systems, and wireless energy management systems and accessories, such as lamps, meters and power supplies. All inventories are stated at the lower of cost or market value with cost determined using the first-in, first-out (FIFO) method. The Company reduces the carrying value of its inventories for differences between the cost and estimated net realizable value, taking into consideration usage in the preceding 12 months, expected demand, and other information indicating obsolescence. The Company records as a charge to cost of product revenue the amount required to reduce the carrying value of inventory to net realizable value. As of March 31, 2012 and September 30, 2012, the Company had inventory obsolescence reserves of $1.5 million and $1.8 million, respectively. Costs associated with the procurement and warehousing of inventories, such as inbound freight charges and purchasing and receiving costs, are also included in cost of product revenue.

Long-Term Receivables The Company records a long-term receivable for the non-current portion of its sales-type capital lease OTA contracts. The receivable is recorded at the net present value of the future cash flows from scheduled customer payments. The Company uses the implied cost of capital from each individual contract as the discount rate.

All inventories are stated at the lower of cost or market value with cost determined using the FIFO method. Other Long-Term Assets Other long-term assets include long-term security deposits, prepaid licensing costs, a note receivable, deferred costs for a long-term contract, and deferred financing costs. Other long-term assets include $87,000 and $73,000 of deferred financing costs as of March 31, 2012 and September 30, 2012. Deferred financing costs related to debt issuances are amortized to interest expense over the life of the related debt issue (5 to 10 years). Accrued Expenses Accrued expenses include warranty accruals, accrued wages and benefits, accrued vacation, sales tax payable and other various unpaid expenses. Accrued expenses include $31,000 and $1.8 million of accrued reorganization costs and contractual commitments as of March 31, 2012 and September 30, 2012. The Company generally offers a limited warranty of one year on its own manufactured products in addition to those standard warranties offered by major original equipment component manufacturers. The manufacturers’ warranties cover lamps and ballasts, which are significant components in the Company’s products.

Company offers a financing program, called an OTA, for a customer’s lease of the Company’s energy management systems. The OTA is structured as a sales-type lease and upon successful installation of the system and customer acknowledgement that the system is operating as specified, revenue is recognized at the Company’s net investment in the lease, which typically is the net present value of the future cash flows. The Company offers a financing program, called a power purchase agreement, or PPA, for the Company’s renewable energy product offerings. A PPA is a supply side agreement for the generation of electricity and subsequent sale to the end user. Upon the customer’s acknowledgement that the system is operating as specified, product revenue is recognized on a monthly basis over the life of the PPA contract, which is typically in excess of 10 years. For sales of solar photovoltaic systems, which are governed by customer contracts that require the Company to deliver functioning solar power systems and are generally completed within three to 15 months, the Company recognizes revenue from fixed price construction contracts using the percentage-of-completion method in accordance with ASC 605-35, Construction-Type and Production-Type Contracts. Under this method, revenue arising from fixed price construction contracts is recognized as work is performed based upon the percentage of incurred costs to estimated total forecasted costs. The Company has determined that the appropriate method of measuring progress on these sales is measured by the percentage of costs incurred to date of the total estimated costs for each contract as materials are installed. The percentage-of-completion method requires revenue recognition from the delivery of products to be deferred and the cost of such products to be capitalized as a deferred cost and asset on the balance sheet. The Company performs periodic evaluations of the progress of the installation of the solar photovoltaic systems using actual costs incurred over total estimated costs to complete a project. Provisions for estimated losses on uncompleted contracts, if any, are recognized in the period in which the loss first becomes probable and reasonably estimable. Revenue is recognized on the sales of our lighting and related energy efficiency systems and products when the following four criteria are met:   <table style="border-collapse:collapse; text-align: left" border="0" cellpadding="0" cellspacing="0" width="100%"> <tr> <td width="4%"> </td> <td width="3%" valign="top" align="left">•</td> <td width="1%" valign="top"> </td> <td align="left" valign="top"> persuasive evidence of an arrangement exists; </td> </tr> </table>   <table style="border-collapse:collapse; text-align: left" border="0" cellpadding="0" cellspacing="0" width="100%"> <tr> <td width="4%"> </td> <td width="3%" valign="top" align="left">•</td> <td width="1%" valign="top"> </td> <td align="left" valign="top"> delivery has occurred and title has passed to the customer; </td> </tr> </table>   <table style="border-collapse:collapse; text-align: left" border="0" cellpadding="0" cellspacing="0" width="100%"> <tr> <td width="4%"> </td> <td width="3%" valign="top" align="left">•</td> <td width="1%" valign="top"> </td> <td align="left" valign="top"> the sales price is fixed and determinable and no further obligation exists; and </td> </tr> </table>   <table style="border-collapse:collapse; text-align: left" border="0" cellpadding="0" cellspacing="0" width="100%"> <tr> <td width="4%"> </td> <td width="3%" valign="top" align="left">•</td> <td width="1%" valign="top"> </td> <td align="left" valign="top"> collectability is reasonably assured </td> </tr> </table> These four criteria are met for the Company’s product-only revenue upon delivery of the product and title passing to the customer. At that time, the Company provides for estimated costs that may be incurred for product warranties and sales returns. Revenues are presented net of sales tax and other sales related taxes. For sales of the Company’s lighting and energy management technologies, consisting of multiple elements of revenue, such as a combination of product sales and services, the Company determines revenue by allocating the total contract revenue to each element based on their relative selling prices. In such circumstances, the Company uses a hierarchy to determine the selling price to be used for allocating revenue to deliverables: (1) vendor-specific objective evidence (VSOE) of fair value, if available, (2) third-party evidence (TPE) of selling price if VSOE is not available, and (3) best estimate of the selling price if neither VSOE nor TPE is available (a description as to how the Company determined VSOE, TPE and estimated selling price is provided below). The nature of the Company’s multiple element arrangements for the sale of its lighting and energy management technologies is similar to a construction project, with materials being delivered and contracting and project management activities occurring according to an installation schedule. The significant deliverables include the shipment of products and related transfer of title and the installation. To determine the selling price in multiple-element arrangements, the Company established VSOE of the selling price for its HIF lighting and energy management system products using the price charged for a deliverable when sold separately. In addition, the Company records in service revenue the selling price for its installation and recycling services using management’s best estimate of selling price, as VSOE or TPE evidence does not exist. Service revenue is recognized when services are completed and customer acceptance has been received. Recycling services provided in connection with installation entail the disposal of the customer’s legacy lighting fixtures. The Company’s service revenues, other than for installation and recycling that are completed prior to delivery of the product, are included in product revenue using management’s best estimate of selling price, as VSOE or TPE evidence does not exist. These services include comprehensive site assessment, site field verification, utility incentive and government subsidy management, engineering design, and project management. For these services and for installation and recycling services, management’s best estimate of selling price is determined by considering several external and internal factors including, but not limited to, pricing practices, margin objectives, competition, geographies in which the Company offers its products and services and internal costs. The determination of estimated selling price is made through consultation with and approval by management, taking into account all of the preceding factors. Deferred revenue relates to advance customer billings, investment tax grants received related to PPAs and a separate obligation to provide maintenance on OTAs, and is classified as a liability on the Consolidated Balance Sheet. The fair value of the maintenance is readily determinable based upon pricing from third-party vendors. Deferred revenue related to maintenance services is recognized when the services are delivered, which occurs in excess of a year after the original OTA is executed.   Income Taxes The Company recognizes deferred tax assets and liabilities for the future tax consequences of temporary differences between financial reporting and income tax basis of assets and liabilities, measured using the enacted tax rates and laws expected to be in effect when the temporary differences reverse. Deferred income taxes also arise from the future tax benefits of operating loss and tax credit carryforwards. A valuation allowance is established when management determines that it is more likely than not that all or a portion of a deferred tax asset will not be realized. For the three months ended September 30, 2012, the Company recorded a full valuation allowance of $5.6 million against its deferred tax assets. ASC 740, Income Taxes, also prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. For those benefits to be recognized, a tax position must be more-likely-than-not to be sustained upon examination. The Company has classified the amounts recorded for uncertain tax benefits in the balance sheet as other liabilities (non-current) to the extent that payment is not anticipated within one year. The Company recognizes penalties and interest related to uncertain tax liabilities in income tax expense. Penalties and interest are immaterial and are included in the unrecognized tax benefits. Deferred tax benefits have not been recognized for income tax effects resulting from the exercise of non-qualified stock options. These benefits will be recognized in the period in which the benefits are realized as a reduction in taxes payable and an increase in additional paid-in capital. For the six months ended September 30, 2011 and 2012, realized tax benefits from the exercise of stock options were $0.8 million and $27,000, respectively. Stock Option Plans The fair value of each option grant for the three and six months ended September 30, 2011 and 2012 was determined using the assumptions in the following table:   <table cellspacing="0" cellpadding="0" width="92%" border="0" style="border-collapse:collapse; text-align: left" align="center">  <tr> <td width="64%"> </td> <td valign="bottom" width="3%"> </td> <td> </td> <td> </td> <td> </td> <td valign="bottom" width="3%"> </td> <td> </td> <td> </td> <td> </td> <td valign="bottom" width="3%"> </td> <td> </td> <td> </td> <td> </td> <td valign="bottom" width="3%"> </td> <td> </td> <td> </td> <td> </td> </tr> <tr> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom" colspan="6" align="center">Three Months Ended September 30,</td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom" colspan="6" align="center">Six Months Ended September 30,</td> <td valign="bottom"> </td> </tr> <tr> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom" colspan="2" align="center" style="border-bottom:1px solid #000000">2011</td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom" colspan="2" align="center" style="border-bottom:1px solid #000000">2012</td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom" colspan="2" align="center" style="border-bottom:1px solid #000000">2011</td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom" colspan="2" align="center" style="border-bottom:1px solid #000000">2012</td> <td valign="bottom"> </td> </tr>   <tr bgcolor="#cceeff"> <td valign="top"> Weighted average expected term </td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom" align="right">6.8 years</td> <td nowrap="nowrap" valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom" align="right">6.0 years</td> <td nowrap="nowrap" valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom" align="right">5.7 years</td> <td nowrap="nowrap" valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom" align="right">5.6 years</td> <td nowrap="nowrap" valign="bottom"> </td> </tr> <tr> <td valign="top"> Risk-free interest rate </td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom" align="right">1.64</td> <td nowrap="nowrap" valign="bottom">% </td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom" align="right">0.9</td> <td nowrap="nowrap" valign="bottom">% </td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom" align="right">1.83</td> <td nowrap="nowrap" valign="bottom">% </td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom" align="right">0.8</td> <td nowrap="nowrap" valign="bottom">% </td> </tr> <tr bgcolor="#cceeff"> <td valign="top"> Expected volatility </td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom" align="right">70</td> <td nowrap="nowrap" valign="bottom">% </td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom" align="right">73</td> <td nowrap="nowrap" valign="bottom">% </td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom" align="right">70</td> <td nowrap="nowrap" valign="bottom">% </td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom" align="right">74.2</td> <td nowrap="nowrap" valign="bottom">% </td> </tr> <tr> <td valign="top"> Expected forfeiture rate </td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom" align="right">11.4</td> <td nowrap="nowrap" valign="bottom">% </td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom" align="right">15.1</td> <td nowrap="nowrap" valign="bottom">% </td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom" align="right">11.4</td> <td nowrap="nowrap" valign="bottom">% </td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom" align="right">15.1</td> <td nowrap="nowrap" valign="bottom">% </td> </tr>  </table> Net Income (Loss) per Common Share Basic net income (loss) per common share is computed by dividing net income (loss) attributable to common shareholders by the weighted-average number of common shares outstanding for the period and does not consider common stock equivalents. Diluted net income (loss) per common share reflects the dilution that would occur if warrants and employee stock options were exercised. In the computation of diluted net income (loss) per common share, the Company uses the “treasury stock” method for outstanding options and warrants. Diluted net income (loss) per common share is the same as basic net income (loss) per common share for the periods ended September 30, 2012, because the effects of potentially dilutive securities are anti-dilutive. The effect of net income (loss) per common share is calculated based upon the following shares (in thousands except share amounts):   <table cellspacing="0" cellpadding="0" width="92%" border="0"

including ballasts and lamps. Purchases from this supplier accounted for 10% and 12% of total cost of revenue for the three and six months ended September 30, 2011, respectively. Currently, the Company has been able to obtain these components from multiple suppliers. For the three months ended September 30, 2012, purchases from two suppliers accounted for 11% and 12% of total cost of revenue. For the six months ended September 30, 2012, no supplier accounted for more than 10% of total cost of revenue. The Company previously purchased a majority of its solar panels from one supplier for its sales of solar generating systems through its Orion Engineered Systems Division. Purchases from this supplier accounted for 15% and 25% of total cost of revenue for the three and six months ended September 30, 2011, respectively. Currently, the Company has been able to obtain panels from multiple suppliers. For the three and six months ended September 30, 2012, panel purchases from one supplier accounted for 11% and 6% of total cost of revenue, respectively. For the three and six months ended September 30, 2011, two customers accounted for 21% of revenue and two customers accounted for 15% and 14% of revenue, respectively. For the three and six months ended September 30, 2012, no customer accounted for more than 10% of revenue. As of March 31, 2012, one customer accounted for 11% of accounts receivable. As of September 30, 2012, one customer accounted for 15% of accounts receivable. Recent Accounting Pronouncements In May 2011, the FASB issued ASU No. 2011-04 Fair Value Measurements (Topic 820): Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in US GAAP and International Financial Reporting Standards (“IFRS”) (“ASU 2011-04”). ASU 2011-04 represents the converged guidance of the FASB and the IASB (the “Boards”) on fair value measurements. The collective efforts of the Boards and their staffs, reflected in ASU 2011-04, have resulted in common requirements for measuring fair value and for disclosing information about fair value measurements, including a consistent meaning of the term “fair value.” The Boards have concluded the common requirements will result in greater comparability of fair value measurements presented and disclosed in financial statements prepared in accordance with GAAP and IFRSs. The amendments in this ASU are required to be applied prospectively, and are effective for interim and annual periods beginning after December 15, 2011. The adoption of ASU 2011-04 did not have a significant impact on the Company’s consolidated financial statements. In June 2011, the FASB issued ASU No. 2011-05, “Comprehensive Income (ASC Topic 220): Presentation of Comprehensive Income,” (“ASU 2011-05”) which amends current comprehensive income guidance. This accounting update eliminates the option to present the components of other comprehensive income as part of the statement of shareholders’ equity. Instead, the Company must report comprehensive income in either a single continuous statement of comprehensive income which contains two sections, net income and other comprehensive income, or in two separate but consecutive statements. ASU 2011-05 will be effective for public companies during the interim and annual periods beginning after December 15, 2011 with early adoption permitted. However, in December 2011, the FASB issued ASU No. 2011-12, “Deferral of the Effective Date for Amendments to the Presentation of Items Out of Accumulated Other Comprehensive Income in Accounting Standards Update No. 2011-05” (“ASU 2011-12”), which deferred the guidance on whether to require entities to present reclassification adjustments out of accumulated other comprehensive income by component in both the statement where net income is presented and the statement where other comprehensive income is presented for both interim and annual financial statements. ASU 2011-12 reinstated the requirements for the presentation of reclassifications that were in place prior to the issuance of ASU 2011-05 and did not change the effective date for ASU 2011-05. For public entities, the amendments in ASU 2011-05 and ASU2011-12 are effective for fiscal years, and interim periods within those years, beginning after December 15, 2011, and should be applied retrospectively. The adoption of ASU 2011-05 and ASU 2011-12 did not have a significant impact on the Company’s consolidated statements as it only requires a change in the format of the current presentation. In December 2011, the FASB issued ASU No. 2011-11, “Balance Sheet: Disclosures about Offsetting Assets and Liabilities.” ASU 2011-11 requires entities to disclose information about offsetting and related arrangements of financial instruments and derivative instruments and will be applied retrospectively for all comparative periods presented. ASU 2011-11 is effective for annual reporting periods beginning on or after January 1, 2013, and interim periods within those annual periods. The Company is currently evaluating the impact of ASU 2011-11.

NOTE C — RELATED PARTY TRANSACTIONS During the six months ended September 30, 2011 and 2012, the Company purchased goods and services from an entity in the amounts of $23,000 and $0, respectively, for which a director of the Company serves as a member of the board of directors. The terms and conditions of such relationship are believed to be not materially more favorable to the Company or the entity than could be obtained from an independent third party.

The note matures on February 15, 2013 and bears interest at 4.5%. The note is secured by the equipment originally leased. Revolving Credit Agreement The Company has a credit agreement (Credit Agreement) with JP Morgan Chase Bank, N.A. (JP Morgan). The Credit Agreement provides for a revolving credit facility (Credit Facility) that matures on June 30, 2013. Borrowings under the Credit Facility are limited to (i) $15.0 million or (ii) during periods in which the outstanding principal balance of outstanding loans under the Credit Facility is greater than $5.0 million, the lesser of (A) $15.0 million or (B) the sum of 75% of the outstanding principal balance of certain accounts receivable of the Company and 45% of certain inventory of the Company. The Credit Agreement contains certain financial covenants, including minimum unencumbered liquidity requirements and requirements that the Company maintain a total liabilities to tangible net worth ratio not to exceed 0.50 to 1.00 as of the last day of any fiscal quarter. The Credit Agreement also contains certain restrictions on the ability of the Company to make capital or lease expenditures over prescribed limits, incur additional indebtedness, consolidate or merge, guarantee obligations of third parties, make loans or advances, declare or pay any dividend or distribution on its stock, redeem or repurchase shares of its stock or pledge assets. The Company also may cause JP Morgan to issue letters of credit for the Company’s account in the aggregate principal amount of up to $2.0 million, with the dollar amount of each issued letter of credit counting against the overall limit on borrowings under the Credit Facility. As of September 30, 2012, the Company had outstanding letters of credit totaling $1.7 million, primarily for securing collateral requirements under equipment operating leases. There were no borrowings by the Company under the Credit Agreement as of March 31, 2012 or September 30, 2012. We were not in compliance with all covenants in the credit agreement as of September 30, 2012 and expect to receive a waiver from our bank for the covenant defaults. The Credit Agreement is secured by a first lien security interest in the Company’s accounts receivable, inventory and general intangibles, and a second lien priority in the Company’s equipment and fixtures. All OTAs, PPAs, leases, supply agreements and/or similar agreements relating to solar PV and wind turbine systems or facilities, as well as all accounts receivable and assets of the Company related to the foregoing, are excluded from these liens. The Credit Agreement provides that the Company has the option to select whether borrowings under the Credit Facility will bear interest at either (i) a daily borrowing LIBOR rate tied to a one-month maturity or (ii) a LIBOR rate tied to a maturity corresponding to an interest period selected by the Company plus, in the case of either (i) or (ii), a per annum rate spread of 2.00%, 2.50% or 3.00%, depending on the ratio of (A) earnings before interest, taxes, depreciation and amortization less income taxes paid in cash less 50% of depreciation expense to (B) the sum of interest expense paid in cash in respect of indebtedness for borrowed money plus scheduled principal payments made with respect to indebtedness for borrowed money, all as determined for the 12-month period ending as of the end of the applicable fiscal quarter. The Company must pay a fee of 0.25% on the average daily unused amount of the Credit Facility and a fee of 2.00% on the daily average face amount of undrawn issued letters of credit. The fee on unused amounts is waived if the Company or its affiliates maintain funds on deposit with JP Morgan or its affiliates above a specified amount. The deposit threshold requirement was met as of September 30, 2012.

NOTE E — INCOME TAXES The income tax provision for the six months ended September 30, 2012 was determined by applying an estimated annual effective tax rate of 53.8% to income (loss) before taxes. For the three months ended September 30, 2012, the Company has recorded a valuation allowance of $5.6 million, equaling the net deferred tax asset due to the uncertainty of its realization value in the future. ASC 740, Income Taxes, requires that a deferred tax asset be reduced by a valuation allowance if there is less than a 50% chance that it will be realized. The determination of the realization of deferred tax assets requires considerable judgment. ASC 740 prescribes the consideration of both positive and negative evidence in evaluating the need for a valuation allowance. Negative evidence for the Company includes a cumulative three year operating loss and limited visibility into future earnings. While the Company has positive evidence with a strong backlog of orders, the Company has determined that the current negative evidence outweighs the current positive evidence and has concluded that the conservative approach is to record a valuation allowance. The estimated effective income tax rate was determined by applying statutory tax rates to pretax income (loss) adjusted for certain permanent book to tax differences and tax credits. Below is a reconciliation of the statutory federal income tax rate and the effective income tax rate:   <table cellspacing="0" cellpadding="0" width="76%" border="0" style="border-collapse:collapse; text-align: left" align="center">  <tr> <td width="72%"> </td> <td valign="bottom" width="12%"> </td> <td> </td> <td> </td> <td> </td> <td valign="bottom" width="12%"> </td> <td> </td> <td> </td> <td> </td> </tr> <tr> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom" colspan="6" align="center">Six Months Ended September 30,</td> <td valign="bottom"> </td> </tr> <tr> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom" colspan="2" align="center" style="border-bottom:1px solid #000000">2011</td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom" colspan="2" align="center" style="border-bottom:1px solid #000000">2012</td> <td valign="bottom"> </td> </tr>   <tr bgcolor="#cceeff"> <td valign="top"> Statutory federal tax rate </td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom" align="right">34.0</td> <td nowrap="nowrap" valign="bottom">% </td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom" align="right">(34.0</td> <td nowrap="nowrap" valign="bottom">)% </td> </tr> <tr> <td valign="top"> State taxes, net </td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom" align="right">9.2</td> <td nowrap="nowrap" valign="bottom">% </td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom" align="right">(2.4</td> <td nowrap="nowrap" valign="bottom">)% </td> </tr> <tr bgcolor="#cceeff"> <td valign="top"> Federal tax credit </td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom" align="right">(11.6</td> <td nowrap="nowrap" valign="bottom">)% </td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom" align="right">(2.0</td> <td nowrap="nowrap" valign="bottom">)% </td> </tr> <tr> <td valign="top"> State tax credit </td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom" align="right">(5.9</td> <td nowrap="nowrap" valign="bottom">)% </td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom" align="right">0.4</td> <td nowrap="nowrap" valign="bottom">% </td> </tr> <tr bgcolor="#cceeff"> <td valign="top"> Change in valuation reserve </td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom" align="right">5.9</td> <td nowrap="nowrap" valign="bottom">% </td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom" align="right">92.7</td> <td nowrap="nowrap" valign="bottom">% </td> </tr> <tr> <td valign="top"> Permanent items </td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom" align="right">10.0</td> <td nowrap="nowrap" valign="bottom">% </td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom" align="right">1.2</td> <td nowrap="nowrap" valign="bottom">% </td> </tr> <tr bgcolor="#cceeff"> <td valign="top"> Change in tax contingency reserve </td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom" align="right">0.8</td> <td nowrap="nowrap" valign="bottom">% </td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom" align="right">(0.1</td> <td nowrap="nowrap" valign="bottom">)% </td> </tr> <tr> <td valign="top"> Other, net </td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom" align="right">1.0</td> <td nowrap="nowrap" valign="bottom">% </td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom" align="right">(2.0</td> <td nowrap="nowrap" valign="bottom">)% </td> </tr> <tr style="font-size:1px"> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom">   </td> <td valign="bottom">   </td> <td> </td> <td valign="bottom"> </td> <td valign="bottom">   </td> <td valign="bottom">   </td> <td> </td> </tr> <tr bgcolor="#cceeff"> <td valign="top"> Effective income tax rate </td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom" align="right">43.4</td> <td nowrap="nowrap" valign="bottom">% </td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom" align="right">53.8</td> <td nowrap="nowrap" valign="bottom">% </td> </tr> <tr style="font-size:1px"> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom">   </td> <td valign="bottom">   </td> <td> </td> <td valign="bottom"> </td> <td valign="bottom">   </td> <td valign="bottom">   </td> <td> </td> </tr>  </table> The Company is eligible for tax benefits associated with the excess of the tax deduction available for exercises of non-qualified stock options, or NQSOs, over the amount recorded at grant. The amount of the benefit is based on the ultimate deduction reflected in the applicable income tax return. Benefits of $1.0 million were recorded in fiscal 2012 as a reduction in taxes payable and a credit to additional paid in capital based on the amount that was utilized during the year. Benefits of $21,000 were recorded for the six months ended September 30, 2012. As of September 30, 2012, the Company had federal net operating loss carryforwards of approximately $11.5 million, of which $3.2 million are associated with the exercise of NQSOs that have not yet been recognized by the Company in its financial statements. The Company also has state net operating loss carryforwards of approximately $6.7 million, of which $2.1 million are associated with the exercise of NQSOs. The Company also has federal tax credit carryforwards of approximately $1.3 million and state tax credits of $0.5 million. For the three months ended September 30, 2012, the Company has recorded a valuation allowance of $5.6 million, equaling the net deferred tax asset due to the uncertainty of its realization value in the future. The Company considers future taxable income and ongoing prudent and feasible tax planning strategies in assessing the need for the valuation allowance. In the event that the Company determines that the deferred tax assets are able to be realized, an adjustment to the deferred tax asset would increase income in the period such determination is made. Uncertain Tax Positions As of September 30, 2012, the balance of gross unrecognized tax benefits was approximately $0.4 million, all of which would reduce the Company’s effective tax rate if recognized. The Company does not expect this amount to change during fiscal 2013 as none of the issues are currently under examination, the statutes of limitations do not expire within the period, and the Company is not aware of any pending litigation. Due to the existence of net operating loss and credit carryforwards, all years since 2002 are open to examination by tax authorities. The Company has classified the amounts recorded for uncertain tax benefits in the balance sheet as other liabilities (non-current) to the extent that payment is not anticipated within one year.

NOTE F — COMMITMENTS AND CONTINGENCIES Operating Leases and Purchase Commitments The Company leases vehicles and equipment under operating leases. Rent expense under operating leases was $0.5 million and $0.4 million for the three months ended September 30, 2011 and 2012, respectively; and $1.0 million and $0.9 million for the six months ended September 30, 2011 and 2012, respectively. The Company enters into non-cancellable purchase commitments for certain inventory items in order to secure better pricing and ensure materials are on hand to meet anticipated order volume and customer expectations, as well as for capital expenditures. As of September 30, 2012, the Company had entered into $11.6 million of purchase commitments related to fiscal 2013, including $1.2 million for operating lease commitments and $10.4 million for inventory purchase commitments. As of September 30, 2012, the Company had entered into an agreement to repurchase $1.5 million of its outstanding common stock.

NOTE G — SHAREHOLDERS’ EQUITY Shareholder Rights Plan On January 7, 2009, the Company’s Board of Directors adopted a shareholder rights plan and declared a dividend distribution of one common share purchase right (a “Right”) for each outstanding share of the Company’s common stock. The issuance date for the distribution of the Rights was February 15, 2009 to shareholders of record on February 1, 2009. Each Right entitles the registered holder to purchase from the Company one share of the Company’s common stock at a price of $30.00 per share, subject to adjustment (the “Purchase Price”).   The Rights will not be exercisable (and will be transferable only with the Company’s common stock) until a “Distribution Date” occurs (or the Rights are earlier redeemed or expire). A Distribution Date generally will occur on the earlier of a public announcement that a person or group of affiliated or associated persons (an “Acquiring Person”) has acquired beneficial ownership of 20% or more of the Company’s outstanding common stock (a “Shares Acquisition Date”) or 10 business days after the commencement of, or the announcement of an intention to make, a tender offer or exchange offer that would result in any such person or group of persons acquiring such beneficial ownership. If a person becomes an Acquiring Person, holders of Rights (except as otherwise provided in the shareholder rights plan) will have the right to receive that number of shares of the Company’s common stock having a market value of two times the then-current Purchase Price, and all Rights beneficially owned by an Acquiring Person, or by certain related parties or transferees, will be null and void. If, after a Shares Acquisition Date, the Company is acquired in a merger or other business combination transaction or 50% or more of its consolidated assets or earning power are sold, proper provision will be made so that each holder of a Right (except as otherwise provided in the shareholder rights plan) will thereafter have the right to receive that number of shares of the acquiring company’s common stock which at the time of such transaction will have a market value of two times the then-current Purchase Price. Until a Right is exercised, the holder thereof, as such, will have no rights as a shareholder of the Company. At any time prior to a person becoming an Acquiring Person, the Board of Directors of the Company may redeem the Rights in whole, but not in part, at a price of $0.001 per Right. Unless they are extended or earlier redeemed or exchanged, the Rights will expire on January 7, 2019. Employee Stock Purchase Plan In August 2010, the Company’s board of directors approved a non-compensatory employee stock purchase plan, or ESPP. The ESPP authorizes 2,500,000 shares to be issued from treasury or authorized shares to satisfy employee share purchases under the ESPP. All full-time employees of the Company are eligible to be granted a non-transferable purchase right each calendar quarter to purchase directly from the Company up to $20,000 of the Company’s common stock at a purchase price equal to 100% of the closing sale price of the Company’s common stock on the NYSE MKT exchange on the last trading day of each quarter. The ESPP allows for employee loans from the Company, except for Section 16 officers, limited to 20% of an individual’s annual income and no more than $250,000 outstanding at any one time. Interest on the loans is charged at the 10-year loan IRS rate and is payable at the end of each calendar year or upon loan maturity. The loans are secured by a pledge of any and all the Company’s shares purchased by the participant under the ESPP and the Company has full recourse against the employee, including offset against compensation payable. The Company had the following shares issued from treasury as of March 31, 2012 and for the six months ended September 30, 2012:   <table cellspacing="0" cellpadding="0" width="100%" border="0"

NOTE H — STOCK OPTIONS, RESTRICTED SHARES AND WARRANTS The Company grants stock options under its 2003 Stock Option and 2004 Stock and Incentive Awards Plans (the Plans). Under the terms of the Plans, the Company has reserved 13,500,000 shares for issuance to key employees, consultants and directors. The options generally vest and become exercisable ratably between one month and five years although longer and shorter vesting periods have been used in certain circumstances. Exercisability of the options granted to employees are contingent on the employees’ continued employment and non-vested options are subject to forfeiture if employment terminates for any reason. Options under the Plans have a maximum life of 10 years. In the past, the Company has granted both ISOs and NQSOs, although in July 2008, the Company adopted a policy of thereafter only granting NQSOs. Certain non-employee directors have elected to receive stock awards in lieu of cash compensation pursuant to elections made under the Company’s non-employee director compensation program. The Plans also provide to certain employees accelerated vesting in the event of certain changes of control of the Company as well as under other special circumstances. In fiscal 2011, the Company converted all of its existing ISO awards to NQSO awards. No consideration was given to the employees for their voluntary conversion of ISO awards. In June 2012, the Compensation Committee of the Board of Directors approved the issuance of restricted shares under the Plans to key employees to provide an opportunity for such employees to earn long-term equity incentive awards. The restricted shares are settled in Company stock when the restriction period ends. Compensation cost for restricted shares granted to employees is recognized ratably over the vesting term, which is between three to five years. Settlement of the shares is contingent on the employees’ continued employment and non-vested shares are subject to forfeiture if employment terminates for any reason. An aggregate of 138,750 of restricted shares were granted on June 18, 2012 valued at a price per share of $2.00, which was the closing market price as of the grant date. Additionally, 25,000 restricted shares were granted on September 27, 2012 valued at a price per share of $1.80, which was the closing market price as of the grant date. For the three and six months ended September 30, 2012, the Company issued zero and 13,547 shares under the 2004 Stock and Incentive Awards Plan to certain non-employee directors who elected to receive stock awards in lieu of cash compensation. The shares were valued at $2.03 per share, the closing market price as of the issuance date. Additionally, during the three and six months ended September 30, 2012, the Company issued zero and 3,000 shares to a consultant as part of a consulting compensation agreement. The shares were valued at $2.03 per share, the closing market price as of the issuance date.

Long-Term Receivables The Company records a long-term receivable for the non-current portion of its sales-type capital lease OTA contracts. The receivable is recorded at the net present value of the future cash flows from scheduled customer payments. The Company uses the implied cost of capital from each individual contract as the discount rate. Also included in other long-term receivables are amounts due from a third party finance company to which the Company has sold, without recourse, the future cash flows from OTAs entered into with customers. Such receivables are recorded at the present value of the future cash flows discounted between 8.8% and 11%.

Net Income (Loss) per Common Share Basic net income (loss) per common share is computed by dividing net income (loss) attributable to common shareholders by the weighted-average number of common shares outstanding for the period and does not consider common stock equivalents. Diluted net income (loss) per common share reflects the dilution that would occur if warrants and employee stock options were exercised. In the computation of diluted net income (loss) per common share, the Company uses the “treasury stock” method for outstanding options and warrants. Diluted net income (loss) per common share is the same as basic net income (loss) per common share for the periods ended September 30, 2012, because the effects of potentially dilutive securities are anti-dilutive. The effect of net income (loss) per common share is calculated based upon the following shares (in thousands except share amounts):   <table cellspacing="0" cellpadding="0" width="92%" border="0"
