Independent Auditors’ Report

To the Stockholders of

Sensor Technologies Incorporated

We have audited the accompanying balance sheet of Sensor Technologies Incorporated (the “Company”) as of December 31, 2009, and the related statements of income, stockholders’ 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 generally accepted auditing standards as established by the Auditing Standards Board (United States) and in accordance with the auditing 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 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 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 Sensor Technologies Incorporated 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.

Note 1 - Nature of Operations and Summary of Significant Accounting Policies (continued)

Revenue Recognition

Revenue on fixed price contracts is recognized upon meeting agreed upon milestones based on progress of the contracts. Revenue on time-and-materials contracts is recognized when the subcontractor invoices to the extent of billable rates times hours delivered, plus other billable costs. Revenue on cost plus fixed fee contracts is recognized to the extent of costs incurred plus a fee earned on work performed.

The Company uses subcontractors to perform a substantial amount of the work required under contracts with the government. In these instances, the Company evaluates whether it acts as the principal or agent in determining the appropriate classification of revenue and related costs. Where the Company is considered the primary contractor and has risk associated with a contract, the Company records the gross amount of the contract revenue.

Sales and profit in connection with contracts to provide services to the U.S. Government that may be at risk of collection because the contracts are incrementally funded and subject to the availability of funds appropriated are deferred until the contract modification is obtained, indicating that adequate funds are available to the contract or task order.

Cost of Services

Costs of services consist primarily of compensation expenses for program personnel, the fringe benefits associated with this compensation and other direct expenses incurred to complete programs, including costs of materials and subcontract efforts.

Property and Equipment

Property and equipment is stated at cost less accumulated depreciation. Depreciation is provided over the estimated useful lives of the assets as follows:

Income Taxes

The Company has elected to be taxed as an S-Corporation for Federal and certain state tax purposes. Under this election, the profits, losses, credits and deductions of the Company are passed through to the individual shareholders.

Advertising Expenses

The Company expenses advertising costs as incurred. Advertising costs for the year ended December 31, 2009 were approximately $57,500.

Note 1 - Nature of Operations and Summary of Significant Accounting Policies (continued)

Stock Based Compensation

The Company accounts for its Stock Based Compensation in accordance with ASC topic 718, “Compensation – Stock Compensation” (“ASC Topic 718”), which requires that compensation cost relating to share-based payment transactions be recognized as an expense in the financial statements over the vesting period and cost measured based on the estimated fair value of the equity or liability instrument at the date issued. The Company uses the Black-Scholes option pricing method to calculate the fair value of its stock options. The expense is recognized on a straight-line basis over the requisite service period.

Accounting Standards Updates

In June 2009, the Financial Accounting Standards Board (“FASB”) issued its final Statement of Financial Accounting Standards (“SFAS)” No. 168 – “The FASB Accounting Standards ASC Topic and the Hierarchy of Generally Accepted Accounting Principles a replacement of FASB Statement No. 162”. (“SFAS No. 168”). SFAS No. 168 made the FASB Accounting Standards Codification (the “ASC”) the single source of U.S. Generally Accepted Accounting Policies (“U.S. GAAP”) used by nongovernmental entities in the preparation of financial statements, except for rules and interpretive releases of the SEC under authority of federal securities laws, which are sources of authoritative accounting guidance for SEC registrants. The ASC is meant to simplify user access to all authoritative accounting guidance by reorganizing U.S. GAAP pronouncements into roughly 90 accounting topics within a consistent structure; its purpose is not to create new accounting and reporting guidance. The ASC supersedes all existing non-SEC accounting and reporting standards and was effective for the Company beginning July 1, 2009. Following SFAS No. 168, the Board will not issue new standards in the form of Statements, FASB Staff Positions, or Emerging Issues Task Force Abstracts; instead, it will issue Accounting Standards Updates. The FASB will not consider Accounting Standards Updates as authoritative in their own right; these updates will serve only to update the ASC topic, provide background information about the guidance, and provide the bases for conclusions on the change(s) in the ASC. In the description of ASC and Accounting Standards Updates (“ASU”) that follows, references in “italics” relate to ASC or ASU topics, and their descriptive titles, as appropriate.

The Company adopted the provisions of “Accounting for Income Taxes” relating to uncertain tax positions on January 1, 2009. There have not been any accruals or disclosures deemed necessary as a result of the adoption. The income tax returns of the Company for 2006, 2007 and 2008 are subject to examination by the IRS and other various taxing authorities, generally for three years after they were filed.

In May 2009, the FASB updated ASC 855, Subsequent Events, which is effective for reporting periods ending after June 15, 2009. ASC 855 establishes general standards of accounting for and disclosure of events that occur after the balance sheet date, but before financial statements are issued, or are available to be issued. The Company adopted the amended sections of ASC 855 and it did not have an impact on the Company’s financial statements. The Company evaluated all events or transactions that occurred after December 31, 2009 through June 28, 2010.

Accounting Standards Update (continued)

In September 2006, the FASB issued FASB ASC 820 “Fair Value Measurements” in order to establish a single definition of fair value and a framework for measuring fair value in generally accepted accounting principles (GAAP) that is intended to result in increased consistency and comparability in fair value measurements. ASC 820 also expands disclosures about fair value measurements.

The provisions of FASB ASC Topic 820 – Fair Value Measurements and Disclosures became effective for the Company’s nonfinancial assets and nonfinancial liabilities that are measured at fair value on a nonrecurring basis on January 1, 2009. The Company’s nonfinancial assets for which the provisions of ASC Topic 820 are now effective include property, plant and equipment. These assets are not measured at fair value on an ongoing basis; however, they are subject to fair value adjustments in certain circumstances, such as when there is evidence of impairment.

The Company’s adoption of ASC Topic 820 had no impact in the carrying values of the Company’s assets and liabilities.

Phase II commenced on August 1, 2008 expiring July 31, 2012. Monthly payments under Phase I and II of the lease are approximately $15,300 and $24,700 respectively.

Note 6 - Employee Benefit Plan

The Company maintains a 401(k) retirement plan for the benefit of all eligible employees. The terms of the plan define eligible employees as those employees who have completed at least 6 months of service and are 21 years of age. Employee contributions are discretionary. Under this Plan the Company may contribute a discretionary matching contribution to the Plan.

The Company may also make a discretionary non-matching contribution to the Plan on behalf of all eligible employees. The Company’s contribution to the Plan was $618,889 for the year ended December 31, 2009. As a result of the acquisition of the Company by ManTech International Corporation in January 2010 (Note 9), the Company’s intent is to terminate the Plan and transfer all assets to the successor plan prior to July 31, 2010.

Note 7 - Stock Options

On January 1, 2005 Sensor Technologies Incorporated Employee Non-Qualified Stock Option Plan (the “Plan”) was amended and restated. The plan is intended to promote the growth and profitability of Sensor Technologies Incorporated (“Company”) whereby the Company may continue to attract, retain, and motivate key employees. Through December 31, 2009, the aggregated number of shares of non-voting common stock authorized for issuance under the Plan was 250. The term of each option granted shall be exercisable for such period as determined by the Board at time of grant and generally vest ratably over a three-year period.

Note 7 - Stock Options (continued)

The weighted average fair value of the options was $859 for the year ended December 31, 2009.

A summary of the Company’s stock option activity and related information for the year ended December 31, 2009 follows:
