REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Partners of

GSE Consulting, LP

Dallas, Texas

We have audited the accompanying balance sheets of GSE Consulting, LP (the “Company”), as of December 31, 2010 and 2009 and the related statements of income, partners’ deficit and cash flows for the years then ended. These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of GSE Consulting, LP, as of December 31, 2010 and 2009 and the results of its operations and cash flows for the years then ended, in conformity with accounting principles generally accepted in the United States of America.

Notes to Financial Statements

NOTE 1 — NATURE OF BUSINESS

GSE Consulting, LP, (the “Partnership”), a Texas Limited Partnership, was formed on July 20, 2004. GSE Consulting GP, LLC is the general partner. Gulf States Energy, Inc. and Glenwood Energy Partners, Ltd are limited partners. The Partnership provides aggregation, marketing, brokerage, and consulting services to commercial, industrial and residential retail customers for electrical power and natural gas. Services are provided to customers throughout the United States, with primary revenues in Texas and the Midwest.

The Partnership is a national energy procurement and management firm helping companies implement strategies to control and reduce energy costs. The Partnership is comprised of energy professionals from leading energy companies across the country. Through strong wholesale trading network and operations, the Partnership is able to leverage its purchasing power across trading regions nationwide to obtain the most aggressive pricing in the marketplace creating maximum savings for its clients.

The Limited Partnership Agreement, which governs the Partnership (the “Agreement”), provides for perpetual existence, until certain circumstances occur that would dissolve the Partnership, such as the sale or other disposition of all or substantially all of the assets of the Partnership, the withdrawal of the general partner or December 31, 2054, unless otherwise extended by the partners.

NOTE 2 — SIGNIFICANT ACCOUNTING POLICIES

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 reported amounts of revenues and expenses during the reporting period. Accordingly, actual results could differ from those estimates.

Revenue Recognition

The Partnership receives commission revenue by providing services to end users of energy (“energy consumers”) to help them attain the best pricing for electrical power and natural gas.

The Partnership earns a commission on energy sales from energy suppliers based on the energy usage transacted between the energy supplier and energy consumer. The Partnership’s commissions are not based on the retail price for electricity; rather on the amount of energy consumed. Commissions are based on the energy usage transacted between the energy supplier and energy consumer multiplied by the contractual commission rate. The contractual commission rate is determined in accordance with an underlying master agreement between the Partnership and each energy supplier. Revenue from commissions is recognized as earned provided there is persuasive evidence of an arrangement, the sales price is fixed or determinable, collection of the related receivable is reasonably assured, and customer acceptance criteria, if any, has been successfully demonstrated. The Partnership recognizes revenue upon the successful brokering of an energy supply contract between energy consumer and energy supplier and cash is received from the energy supplier.

Channel Partner Commissions

The Partnership pays commissions to its channel partners and sales personnel at contractual rates based on cash collections from energy suppliers. These commissions are charged to sales and marketing expense as revenue is recognized. A portion of the sales force commission is allocated to cost of revenue based on the estimated time each sales rep spends on brokering transactions with energy suppliers.

NOTE 2 — SIGNIFICANT ACCOUNTING POLICIES (continued)

Cash

The Company considers all highly liquid debt instruments with an original maturity date of three months or less at time of purchase to be cash equivalents. As of December 31, 2010 and 2009, cash equivalents consisted primarily of non-interest bearing accounts with financial institutions and is insured with the Federal Deposit Insurance Company (“FDIC”).

Property and Equipment

Property and equipment, including leasehold improvements, are stated at cost and are depreciated using the straight-line method over the respective asset lives, as follows:

Income Taxes

The Partnership is organized as a limited partnership under the laws of the State of Texas. As a result, the Partnership is not directly subject to federal income taxes under the provisions of the Internal Revenue Code and applicable state laws. Items of income or loss are allocated to the partners in accordance with the Partners’ ownership interests and reported on their individual federal and state income tax returns. No provision for federal and state income taxes has been included in the accompanying financial statements and, with a few exceptions, the Partnership is no longer subject to U.S. federal, state and local or non-U.S. income tax examinations by tax authorities for years before 2007.

In accordance with Financial Accounting Standards Board Accounting Standards Codification Topic 740, Income Taxes, accounting principles generally accepted in the United States of America require the Partnership to evaluate tax positions taken and recognize a tax liability if it is more-likely-than-not that uncertain tax positions taken would not be sustained upon examination by taxing authorities. The Partnership has analyzed tax positions taken and has concluded that, as of and for the nine months ended September 30, 2011 (unaudited) and as of December 31, 2010 and 2009, there are no uncertain tax positions taken or expected to be taken that would require recognition of a liability or disclosure in these financial statements.

As of and for the nine months ended September 30, 2011 (unaudited) and as of December 31, 2010 and 2009, the Partnership had no interest and penalties related to income taxes.

Concentration of Credit Risk

Financial instruments that potentially expose the Partnership to concentrations of credit risk consist principally of its relationship with energy suppliers. The Partnership has no significant off-balance sheet risk such as foreign exchange contracts, option contracts, or other foreign hedging arrangements. The Partnership places its cash with primarily one institution, which management believes is of high credit quality.
