REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Board of Directors

Stanley Baker Hill, LLC

Beaver, Pennsylvania

We have audited the accompanying balance sheet of Stanley Baker Hill, LLC (Company) as of December 31, 2009, and the related statements of operations and changes in members equity and cash flows for the year 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 audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards
require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. The Company is not required to have, nor were we engaged to perform, an audit of its internal control
over financial reporting. Our audit included 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 includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An
audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audit provides 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 Stanley Baker Hill, LLC as of December 31, 2009, and the results of its operations and its cash flows for the year then ended in conformity with accounting principles generally accepted in the United States of America.

STANLEY BAKER HILL, LLC

NOTES TO FINANCIAL STATEMENTS

DECEMBER 31, 2009

NOTE 1ORGANIZATION

Stanley Baker Hill, LLC (Company) is a joint venture formed in February 2004 between Stanley Consultants, Inc. (Stanley), Michael Baker, Jr., Inc. (Baker) and Hill International, Inc. (Hill). The Company
provides various architect-engineer services in Iraq for the U.S. Army Corps of Engineers Transatlantic Program Center (U.S. Corps). The Company has a contract for an indefinite delivery and indefinite quantity for construction management and
general architect-engineer services for facilities in Iraq with U.S. Corps. Anticipated completion of open contracts is likely to occur in September 2010, barring any additional new contracts or modification to existing contracts obtained in 2010.

NOTE 2SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

A summary of significant accounting policies consistently applied by management in the preparation of the accompanying financial statements follows:

The Financial Accounting Standards Board (FASB) issued the FASB Accounting Standards Codification (Codification). The Codification became the
single source of authoritative nongovernmental United States generally accepted accounting principles (GAAP), superseding existing FASB, American Institute of Certified Public Accountants, Emerging Issues Task Force and related literature. The
Codification eliminates the previous GAAP hierarchy and establishes one level of authoritative GAAP. All other literature is considered nonauthoritative. The Codification was effective for fiscal years ending after September 15, 2009.

Use of EstimatesThe preparation of financial statements in conformity with generally accepted accounting principles
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 revenues and
expenses during the reporting period. Actual results could differ from those estimates.

Operating CycleThe
Companys work is performed under cost-plus-fee contracts and fixed-price contracts. The length of the Companys contracts varies, but is typically less than a year. Assets and liabilities related to long-term contracts are included in
current assets and current liabilities in the accompanying balance sheets, since they will be satisfied in the normal course of contract completion, although that might require more than one year at times.

Cash and Cash EquivalentsThe Company maintains, at various financial institutions, cash and certificates of deposit that might exceed
federally insured amounts at times. For purposes of the statements of cash flows, the Company considers all interest-bearing money market funds and noninterest-bearing accounts to be cash and cash equivalents.

Revenue Recognition and Contract AccountingThe Company typically incurs direct labor costs, subcontractor costs and certain other
indirect costs (ODCs) in connection with architect-engineer services. Contracts are structured such that margin is earned on labor costs and not on ODCs. The Company includes revenues related to its direct labor, subcontractors and ODCs in its total
contract revenues as long as the Company remains responsible to the client for the acceptability of the services provided.

The Company recognizes revenues under the percentage-of-completion method of accounting. Revenues on fixed-price contracts with a predetermined scope of work are determined by multiplying the estimated margin at completion for each contract
by the projects percentage of completion to date, adding labor costs, subcontractor

NOTE 2SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES(Continued)



costs and ODCs incurred to date, and subtracting revenues recognized in prior periods. In applying the percentage-of-completion method to these contracts, the Company measures the extent of
progress toward completion as the ratio of labor costs incurred to date over total estimated labor costs at completion. As work is performed under contracts, estimates of the costs to complete are regularly reviewed and updated. As changes in
estimates of total costs at completion on projects are identified, appropriate earnings adjustments are recorded during the period that the change is identified.

For contracts with predetermined time period of service, revenue is recognized on a ratio of time elapsed as compared to the total length of the contract.

The majority of new task orders in 2009 were fixed-price contracts, and the remaining new task orders were time-and-materials arrangements.
For time-and-materials task orders, revenue is recognized and billed by multiplying the number of hours expended by our professionals in the performance of the contract by the established billing rates.

Provisions for estimated losses on uncompleted contracts are recorded during the period in which such losses are determined. Revenues
related to contractual claims that arise from customer-caused delays or change orders unapproved as to both scope and price are recorded only when the amounts have been agreed with the client. Profit incentives and/or award fees are recorded as
revenues when the amounts are both probable and reasonably estimable.

The current asset, Costs and estimated earnings
in excess of billings on uncompleted contracts, represents revenue recognized in excess of amounts billed. The current liability, Billings in excess of costs and estimated earnings on uncompleted contracts, represents amounts
billed in excess of revenue recognized.

Equipment and Leasehold ImprovementsEquipment and leasehold improvements are
stated at the lower of cost or fair value. Depreciation and amortization are provided on the straight-line method over the estimated useful lives of the assets. Repairs and maintenance that do not extend the lives of the applicable assets are
charged to expense as incurred. Gain or loss resulting from the retirement or other disposition of assets is included in income.

Income TaxesThe Company is organized as an LLC and is not subject to federal or state income taxes. Accordingly, no provision has been made for current or deferred income taxes in these financial statements. The taxable income of the
Company is included in the tax returns of the individual members.

Effective January 1, 2009, the Company adopted the
Codification Topic for Income Taxes, which prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. This topic also provides
guidance on de-recognition, classification, interest and penalties, disclosure and transition. The adoption of this topic did not have a material impact on the Companys consolidated financial statements. As of December 31, 2009, no
liability for unrecognized tax positions was required to be recorded.

Subsequent EventsSubsequent events are defined as
events or transactions that occur after the balance sheet date, but before the financial statements are issued or are available to be issued. Management has evaluated subsequent events through February 12, 2010, the date on which the financial
statements were available to be issued.

cash flow of the Company.

NOTE 8FAIR VALUE MEASUREMENTS

The Companys financial instruments consist primarily of cash, receivables, accounts payable and other current liabilities. The carrying
amount of these assets and liabilities approximate fair value due to the short-term nature of such instruments.
