REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors

CACI International Inc

We have audited the accompanying consolidated balance sheets of the Defense and Intelligence Group of American Management Systems, Inc. (“D&IG”) as of December 31, 2003 and 2002, and the related consolidated statements of operations, group’s equity, and cash flows for each of the three years in the period ended December 31, 2003. These consolidated financial statements are the responsibility of the D&IG’s management. Our responsibility is to express an opinion on these consolidated 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 audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. 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 audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the consolidated financial position of the Defense and Intelligence Group of American Management Systems, Inc. at December 31, 2003 and 2002, and the consolidated results of its operations and its cash flows for each of the three years in the period ended December 31, 2003 in conformity with U.S. generally accepted accounting principles.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(amounts in thousands)

NOTE 1 – NATURE OF OPERATIONS AND SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

American Management Systems, Inc. (“AMS”) was incorporated in February 1970 to provide IT consulting to government, financial services and communications industries. The Defense and Intelligence Group (“D&IG”) of AMS provided defense and intelligence agencies of the U.S. Federal Government with business management solutions including information technology and design in support of acquisition, financial management, engineering services and logistics, warfighting and intelligence missions.

On March 10, 2004 AMS announced its approval of an Agreement and Plan of Merger with CGI Group, Inc. and CGI Virginia Corporation which provided for a tender offer to purchase all the issued and outstanding shares of common stock and a merger of CGI Virginia Corporation into AMS. AMS also announced its approval of an Asset Purchase Agreement with CACI International Inc, CACI, INC. – FEDERAL, CACI Enterprise Solutions, Inc. and CGI Group, Inc. for the acquisition by CACI Enterprise Solutions, Inc. of certain assets and the assignment of certain liabilities associated with the D&IG immediately upon the satisfaction of the conditions to the tender offer. On May 1, 2004 CACI Enterprise Solutions, Inc. completed the purchase of the D&IG for $415 million in cash. The accompanying consolidated financial statements present the financial condition, results of operations and cash flows of the D&IG.

AMS did not report separate financial statements for the D&IG nor maintain its financial records to capture assets, liabilities and indirect costs for the D&IG. Since the D&IG could not be reported on as a separate business unit for financial statement purposes, certain allocations of assets, liabilities and costs were allocated to the D&IG that management believes are equitable and provide a reasonable estimate of the costs attributed to the D&IG. The following is a brief summary of the allocation methodology for significant financial statement captions:

Statements of Operations

Revenue and direct costs were specifically identified by contracts associated with the D&IG. Indirect costs were allocated based upon indirect rates calculated in accordance with the AMS’ costs disclosure statement. These allocations were then adjusted for specific one-time charges that did not relate to the D&IG business such as contract litigation costs or asset write-downs. Income taxes were calculated as if the D&IG were a stand alone taxable entity during the periods presented.

Balance Sheets

Billed and unbilled accounts receivable were specifically identified based on the contracts associated with the D&IG.

Certain prepaids and other assets were specifically identified such as software licenses. Other assets purchased on behalf of AMS such as insurance policies were allocated using an income statement percentage approach, i.e. comparing the D&IG’s revenue or expense to AMS’ total revenue or expense, as appropriate.

DEFENSE AND INTELLIGENCE GROUP OF AMERICAN MANAGEMENT SYSTEMS, INC

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - continued

(amounts in thousands)

Property and equipment was specifically identified based on locations in which the D&IG employees work. Other fixed assets were allocated using an income statement percentage approach.

Accounts payable and accrued expenses were determined primarily using an income statement percentage approach based on cost relationships. Certain material accrued expenses that could be specifically identified such as deferred maintenance revenue were also recorded to the D&IG balance sheet.

Interim Results

The accompanying unaudited condensed consolidated financial statements as of March 31, 2004 and for the three months ended March 31, 2004 and 2003, have been prepared pursuant to generally accepted accounting principles in the United States. In the opinion of management, the accompanying unaudited interim consolidated financial statements reflect all necessary adjustments and reclassifications (all of which are a normal, recurring nature) that are necessary for fair presentation for the periods presented. It is suggested that these unaudited consolidated financial statements be read in conjunction with the audited consolidated financial statements included herein. The current period’s results of operations are not necessarily indicative of results that may be achieved for any future period.

A. Principles of Consolidation

The consolidated financial statements include the accounts of the D&IG and an allocation of the accounts of R.M. Vredenburg & Co. (“Vredenburg”) based on contracts acquired by CACI. Vredenburg was a wholly-owned subsidiary of AMS that was acquired in August 2003 (see Note 2). All significant intragroup and intercompany balances and transactions have been eliminated in consolidation.

B. Revenue Recognition

Revenue on time-and-materials contracts was recognized to the extent of billable rates times hours delivered plus expenses incurred. Revenue on cost-reimbursable contracts was recognized to the extent of costs incurred plus either a proportionate amount of the fee earned or the entire amount of the fee awarded. For fixed-price contracts, where the D&IG has the ability to produce reasonably dependable estimates regarding revenue and costs, revenue was recognized using the percentage-of-completion basis of accounting based on the percentage of costs incurred in relation to total estimated costs to be incurred. The estimates utilized on these contracts were continually updated during the terms of the contracts and may have resulted in the revision of recognized revenue and estimated costs in the period in which they were identified.

Large systems integration projects are generally either fixed-price or time-and-materials contracts that are structured in phases (design, development and implementation) for delivery and contract management purposes. These long-term production-type contracts generally include the delivery of software, integration and customization services, training and maintenance. In accordance with the American Institute of Certified Public Accountants’ Statement of Position No. 97-2, Software Revenue Recognition (“SOP 97-2”), when these software licenses require significant production, modification, or customization, the entire arrangement is accounted for in accordance with Accounting Research Bulletin No. 45, Long-Term Construction-Type Contracts, using the relevant guidance in SOP No. 81-1, Accounting for Performance of Construction-Type and Certain Production-Type Contracts (“SOP 81-1”). Because the arrangements are accounted for under SOP 81-1, the entire contract values are recognized as revenue using the percentage-of-completion basis of accounting.

Typically, the D&IG bundled software licenses with services. When no significant production, modification or customization of the software was required, the D&IG allocated a portion of the contract value to each element of the contract based on its relative vendor specific objective evidence of fair value (“VSOE”). Generally the D&IG was able to establish VSOE for all elements of the arrangement and bifurcate the contract value accordingly. In these circumstances, revenue was recognized on each element separately. Revenue on software license fees was recognized when a non-cancelable license agreement was in force, the software was delivered, the license fee was fixed or determinable, and collection was deemed probable. In certain circumstances, the D&IG was not able to establish

8

DEFENSE AND INTELLIGENCE GROUP OF AMERICAN MANAGEMENT SYSTEMS, INC

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - continued

(amounts in thousands)

VSOE for the software. In these situations, once the software was delivered and the only undelivered element was services, the entire contract value was recognized over the service period. The D&IG was unable to establish VSOE for software it sells as part of a multiple-element arrangement when the software product had not yet been sold separately and a standard price list was not established. In such circumstances, when VSOE was established for the undelivered elements in the arrangement (which generally consist of maintenance, training, data conversion or other services), the D&IG used the residual method, in accordance with SOP 97-2, to determine the value of the software to recognize. When VSOE could not be established for the undelivered services, the entire contract value was recognized over the same period.

The D&IG also entered into contracts with customers that did not include the sale or integration of software. These contracts included services such as general consulting or training and were typically performed on a time-and-materials or cost-reimbursable basis. When such contracts were performed on a fixed-price basis, the D&IG recognized revenue as earned in accordance with SEC Staff Accounting Bulletin No. 101, Revenue Recognition in Financial Statements (“SAB 101”), as services were performed and were contractually billable. The D&IG records revenue for award fees related to contracts recognized under SAB 101 upon notification from the customer that the fee has been awarded.

Maintenance and product support agreements generally provide for minor programming corrections, new releases and help-desk support. The terms of these agreements may vary with each customer but maintenance and product support are typically sold for a twelve-month period with renewals occurring annually based on renewal rates stated in the original contract. The D&IG generally invoices and requires the customer to pay in advance of the maintenance period. Prepaid maintenance was deferred and recognized ratably over the maintenance period.

Losses on contracts, if any, were recognized during the period in which the loss first became probable and reasonably estimable. Any projected loss recognized was based on the D&IG’s best estimates of a contract’s revenue and costs. Any contract losses recognized were periodically reviewed for accuracy as total revenue and total cost to complete estimates were updated during the term of the contract.

Revenue recognized in excess of billings was recorded as unbilled accounts receivable. Cash collections in excess of revenue recognized were recorded as deferred revenue until the revenue recognition criteria were met. Substantially all of the revenue and related accounts receivable of the D&IG is generated from agencies and departments of the U.S. Federal Government. Reimbursements, including those relating to travel, other out-of-pocket expenses, and any third-party costs, were included in revenue, and an equivalent amount of reimbursable expenses were included in direct costs. The D&IG regularly assesses the billed and unbilled balances and records an allowance for doubtful accounts equal to the amount estimated to be not collectible.

The costs associated with cost-type federal government contracts are subject to audit and adjustment by the U.S. Government. In the opinion of the D&IG management, no significant adjustments or disallowances of costs are anticipated beyond any such amounts provided for in the consolidated financial statements.

C. Developed Computer Software

The D&IG developed proprietary software products which were then licensed to customers either as stand-alone applications or as elements of custom-built systems. The D&IG capitalized the costs incurred for development of software for external sale after technological feasibility had been established in accordance with Statement of Financial Accounting Standards (“SFAS”) No. 86, Accounting for the Costs of Computer Software to be Sold, Leased, or Otherwise Marketed (“SFAS 86”). Costs incurred prior to the establishment of technological feasibility were charged to research and development expense. When the software was ready for general release to customers, capitalization ceased and such costs were amortized on a straight-line basis over the estimated economic life, which was generally three to five years.

9

DEFENSE AND INTELLIGENCE GROUP OF AMERICAN MANAGEMENT SYSTEMS, INC

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - continued

(amounts in thousands)

In accordance with SFAS 86, on a quarterly basis the D&IG performed net realizable value (“NRV”) analyses on each capitalized software product to ensure that the value of the product meets or exceeds the expected total amount to be capitalized on the development as well as to evaluate the economic life of the product. The NRV analyses consider the expected future sales pipeline and revenue projections associated with the products. When updating the NRV analyses, if the D&IG noted a change in the expected revenue stream demonstrating declining revenue trends, the D&IG either accelerated the amortization or wrote-off the unamortized software development costs that exceeded the expected NRV.

Product development for the years ended December 31, was as follows:

	2003		2002		2001
Capitalized	$	11,678	$	6,653	$	4,479
Expensed		694		2,394		1,469
Acquired		2,762		—		—
	$	15,134	$	9,047	$	5,948

The D&IG acquired $2,762 of developed computer software during August 2003 as a result of the acquisition of 100% of the outstanding common stock of Vredenburg (see Note 2).

The D&IG recorded total amortization expense on developed computer software of $2,884 in 2003, $1,107 in 2002, and $0 in 2001. Unamortized costs of developed software were $21,028 and $10,406 at December 31, 2003 and 2002, respectively.

D. Impairment of Long-Lived Assets

In accordance with SFAS No. 144, Accounting for the Impairment or Disposal of Long-Lived Assets, the D&IG recognizes an impairment loss when circumstances indicate that the carrying value of long-lived tangible and intangible assets with finite lives may not be recoverable. Recoverability of long-lived assets is assessed by a comparison of the carrying amount to the estimated future net cash flows. If estimated future undiscounted net cash flows are less than the carrying amount, the asset is considered impaired and expense is recorded at an amount required to reduce the carrying amount to fair value. Long-lived tangible and intangible assets primarily include property and equipment, developed computer software, and intangible customer relationships associated with Vredenburg. The D&IG recorded software asset impairments of $3,175 in 2003 for the write-off of certain non-performing software assets that were no longer expected to provide future value, which is included in indirect costs and selling expenses in the accompanying consolidated statement of operations.

E. Stock-Based Compensation

Some of the D&IG’s employees participated in various equity compensation plans sponsored by AMS. AMS’ plans authorize grants of stock options and restricted stock with respect to AMS’ common stock.

The D&IG elected to account for its participation in AMS’ stock-based compensation plans using the intrinsic value method under Accounting Principles Board Opinion No. 25, Accounting for Stock Issued to Employees and to disclose pro forma effects on net (loss) income as provided by the provisions of SFAS No. 148, Accounting for Stock-Based Compensation – Transition and Disclosure and Statement of Financial Accounting Standards No. 123, Accounting for Stock-Based Compensation (“SFAS 123”). Accordingly, no compensation cost for stock options held by employees of the D&IG has been recognized. Had compensation cost for stock options been determined based on the fair value at the grant dates in 2003, 2002, and 2001 consistent with the provisions of SFAS 123, the pro forma net (loss) income would have been as follows:

								(unaudited)

For 2003, 2002, and 2001 disclosure purposes, the fair value of each stock option granted was estimated on the date of grant using the Black-Scholes option-pricing model. For March 31, 2004 disclosure purposes, the fair value of each stock option granted was determined by measuring the value of compensation to the employee which was based on the difference between the stock price at the grant date and the purchase price of AMS stock at $19.40 per share by CGI Group, Inc. These options would be amortized on a pro-forma basis based on the vesting schedule specified in the option agreement. The fair value of the options granted for the years ended December 31, 2003, 2002, and 2001 were $6.74, $11.22, and $9.74, respectively. The fair value of the D&IG’s participation in AMS’ stock-based option awards to employees was estimated assuming no expected dividends and the following weighted-average assumptions:

	Year Ended December 31,
	2003		2002		2001
Risk-free interest rate	3.0	%	4.0	%	5.0	%
Expected life (years)	5		5		6
Expected volatility	66.0	%	66.7	%	57.4	%

F. Income Taxes

Deferred tax assets and liabilities were determined based on the difference between the financial statement and tax bases of assets and liabilities, using enacted tax rates for the year in which the differences are expected to reverse.

Deferred income taxes are provided for temporary differences in recognizing certain income, expense, and credit items for financial reporting purposes and tax reporting purposes. Such deferred income taxes primarily relate to the methods of accounting for revenue, capitalized software development costs and restricted stock. A valuation allowance is recorded if it is “more likely than not” that some portion or all of a deferred tax asset will not be realized.

G. Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities, and the reported amounts of revenue and expenses reported during the period. Actual results could differ from these estimates.

NOTE 2 – ACQUISITIONS

Vredenburg

On August 1, 2003, AMS acquired 100% of the outstanding common stock of Vredenburg, a provider of professional and technical services to the Department of Defense and U.S. Intelligence communities. The results of operations of Vredenburg have been allocated to the consolidated financial statements since August 1, 2003, the acquisition date. The acquisition adds critical infrastructure protection capabilities, sophisticated document management technologies, and new program management expertise to AMS’ offerings in financial management, acquisition and procurement, business intelligence, enterprise architecture, and technology consulting.

The aggregate purchase price paid by AMS, net of $585 in cash acquired, was $46,939 and included cash payments through December 31, 2003 of $42,939. Amounts remaining to be paid by AMS at December 31, 2003 consisted of $4,000 of payments related to earn-out targets for which all contingencies were resolved and full payment was made on January 30, 2004.

The purchase price allocation has been prepared on a preliminary basis by AMS, and reasonable changes are expected as additional information becomes available. The estimated fair values of assets acquired and liabilities assumed as of the date of the acquisition have been allocated to the D&IG based on the 2003 Vredenburg revenue acquired by CACI as a percentage of total 2003 Vredenburg revenue, and are allocated as follows:

Accounts receivable	$	13,071
Other current assets, net of cash acquired		3,727
Other noncurrent assets		4,267
Developed computer software		2,762
Other intangible assets		13,962
Goodwill		26,720
Allocation of assets acquired		64,509
Short-term debt		(1,015	)
Accounts payable and other current liabilities		(12,291	)
Long-term debt		(1,477	)
Other noncurrent liabilities		(5,088	)
Allocation of liabilities assumed		(19,871	)
Allocation of net assets acquired	$	44,638

The developed computer software assets have estimated useful lives of five years. The D&IG’s allocation of other intangible assets consist of customer relationships of $13,518, net of accumulated amortization of $444 at December 31, 2003. Customer relationships have a weighted average useful life of 14 years. Other intangible assets are being amortized on a straight-line basis over periods ranging from 10 to 15 years based on their estimated useful lives. Amortization expense from the date of acquisition through December 31, 2003 was $444 and $266 for the quarter ended March 31, 2004. Future amortization expense related to other intangible assets is expected to be $1,065 in each of the years ending December 31, 2004, 2005, 2006, 2007 and 2008. None of the goodwill is expected to be deductible for tax purposes.

The D&IG results of operations for the year ended December 31, 2003 include the operating results of this acquisition from August 1, 2003 through December 31, 2003. The following unaudited pro forma condensed financial information is based on the historical financial statements of the D&IG and Vredenburg adjusted to give effect to the Vredenburg acquisition as if it had occurred on the beginning of each period presented.

	Years ended December 31,
	2003			2002
Pro Forma:
Revenue	$	285,295		$	255,944
Net (loss) income	$	(3,281	)	$	5,863

NOTE 3 – PROPERTY AND EQUIPMENT

Property and equipment is recorded at cost. Depreciation of equipment has been provided over the estimated useful life of the respective assets (ranging from three to ten years) using the straight-line method. Leasehold improvements are generally amortized using the straight-line method over the remaining lease term or the useful life of the improvements, whichever is shorter. Costs for maintenance and repairs are charged to expense when incurred. Property and equipment consists of the following at December 31:

	2003			2002
Equipment and furniture	$	10,247		$	9,066
Leasehold improvements		3,592			3,388
Allocated property and equipment		6,396			4,971
		20,235			17,425
Less accumulated depreciation and amortization		(14,415	)		(11,972	)
Total property and equipment, net	$	5,820		$	5,453

Depreciation and leasehold amortization expense was $2,526 in 2003, $2,695 in 2002 and $2,417 in 2001.

NOTE 4 – OTHER ASSETS

At December 31, 2003 other assets consisted of $7,186 for an allocation of company-owned life insurance and $706 of other deferred fees, accrued long-term interest, and notes receivable. At December 31, 2002, other assets consisted of $9,019 for an allocation of company-owned life insurance and $663 of other deferred fees, accrued long-term interest and notes receivable. Effective January 1, 2004, AMS established new deferred compensation plans. Participants in the prior plans either rolled-over their existing balances to the new plans or received distributions. Distributions from the prior plans were funded from collapse of company-owned life insurance plans, therefore, the balance of company-owed life insurance was $0 as of March 31, 2004. Other assets as of March 31, 2004 consisted of $912 of deferred fees, accrued long-term interest and notes receivable.

NOTE 5 – EMPLOYEE SHARE PLANS

2003 Stock Incentive Plan

On May 9, 2003, the stockholders of AMS approved the 2003 Stock Incentive Plan (the “2003 Plan”). The 2003 Plan permits awards to all employees (including the D&IG employees) of stock options (incentive stock options and non-qualified stock options), restricted stock awards, stock appreciation rights, performance shares, performance units,

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - continued

(amounts in thousands)

stock unit awards, and other incentive awards. The 2003 Plan authorizes the issuance of 4,500 shares of AMS’ common stock plus certain remaining shares, subject to the terms of the 2003 Plan, available under AMS’ 1996 Amended Stock Option Plan F, 1999 Contractor Stock Option Plan, Stock Option Plan for Employees and Restricted Stock and Stock Bonus Plan (collectively, the “Prior Plans”). As of December 31, 2003, 5,377 shares were available for grant under the 2003 Plan.

All option awards granted under the 2003 Plan have been granted at the fair market value of the common stock on the date of grant. The terms of the awards are fixed on the date of grant. Options granted in 2003 under the 2003 Plan generally become exercisable over a three- or four-year vesting period beginning on the first anniversary of the date of grant. Options granted under the 2003 Plan expire no more than ten years from the date of grant. Restricted stock awards granted under the 2003 Plan generally are subject to restrictions for a minimum of three years from the date of grant. Performance awards may be issued upon the achievement of certain performance criteria and only after the end of the relevant performance period as set forth in the applicable award agreement. Stock unit awards will generally have a vesting period of not less than three years.

Prior Stock Option Plans

Under AMS’ 1996 Amended Stock Option Plan F (“Plan F”) which was stockholder approved, up to 5,800 shares were authorized for issuance pursuant to incentive stock options or non-qualified stock options granted to employees (including the D&IG employees) and non-employee directors. Options that were granted under Plan F expire no later than ten years from the date of grant. After the adoption of the 2003 Plan as of May 9, 2003, AMS did not make any grants under Plan F.

AMS also has an equity incentive plan, the Stock Option Plan for Employees, which was adopted by the Board on July 27, 2001. This plan is not stockholder approved. Under this plan, up to 1,000 shares were authorized for issuance to employees of AMS (including the D&IG employees) pursuant to non-qualified stock options. The maximum vesting and life of shares granted under this plan was ten years from the date of grant. After the adoption of the 2003 Plan as of May 9, 2003, AMS did not make any grants under this plan.

The exercise price of stock options granted under all Prior Plans is not less than the fair market value on the date of grant. Options granted under the Prior Plans may be exercisable immediately, in monthly installments, or in annual installments, as set forth in option agreements.

Restricted Stock

AMS has a Restricted Stock and Stock Bonus Plan (the “Restricted Stock Plan”), adopted by the Board on May 11, 1990, which is not stockholder approved. Pursuant to the Restricted Stock Plan, restricted shares were granted to employees of AMS (including the D&IG employees) as discretionary awards or as profit-sharing awards upon the attainment of certain performance objectives. Restrictions on shares generally lapse over a three-year period. In certain circumstances, the receipt of discretionary awards could be deferred to a later specified date.

Unearned compensation was recorded for restricted stock on the dates that restricted stock was granted based upon the market value of the shares. Compensation expense, allocated to the D&IG financial statements, for which restricted stock was granted was $382, $780 and $495 for the years ended December 31, 2003, 2002 and 2001, respectively.

NOTE 6 – INCOME TAXES

Income before taxes for the D&IG was derived solely in the United States for each of the three years in the period ended December 31,2003. The (benefit) provision for income taxes for the years ended December 31, consisted of:

Employee Benefit Plans

AMS maintained a 401(k) defined contribution plan covering substantially all U.S. employees, including those in the D&IG. This 401(k) plan does not provide matching contributions.

AMS had a simplified employee pension plan. This plan was a defined contribution plan whereby AMS made contributions, which were based on the application of a percentage specified by AMS to the qualified gross wages of eligible employees. Total plan expense allocated to the D&IG was approximately $5,231 in 2003, $3,966 in 2002, and $3,563 in 2001.

Deferred Compensation

The D&IG participated in deferred compensation plans that were implemented in late 1996, and permitted eligible employees to defer an elected portion of their compensation. The deferred compensation earned a specified rate of return. As of December 31, 2003 and 2002, the D&IG had accrued $8,035 and $9,015, respectively, of which $5,392 and $3,315, respectively, was classified as a current liability. The D&IG recorded interest expense of $581, $621, and $568 in 2003, 2002, and 2001, respectively, related to the earnings by the deferred compensation plan participants.

To fund these plans, the D&IG purchased company-owned life insurance contracts which were held by an irrevocable grantor trust. Charges to other expense associated with these contracts were $343, $549, and $457 in 2003, 2002, and 2001, respectively, which were offset by other income to adjust the contracts to their cash surrender values of $365, $44, and $84 in 2003, 2002, and 2001, respectively. Proceeds from the insurance policies are payable to the D&IG upon death of the insured. During 2001, AMS received proceeds of $1,810 associated with one of these policies, which resulted in a $305 gain allocated to the D&IG.

Severance and Closure of Facilities

	Severance			Facilities			Total
2001 Charge	$	6,804		$	3,956		$	10,760
Cash payments		(5,670	)		(675	)		(6,345	)

2002 Charge		3,823			1,133			4,956
Cash payments		(4,201	)		(1,278	)		(5,479	)
Liability as of December 31, 2002		756			3,136			3,892
2003 Charge		4,972			1,857			6,829
Cash payments		(5,004	)		(1,221	)		(6,225	)
Liability as of December 31, 2003	$	724		$	3,772		$	4,496

In an effort to achieve cost reductions and align its work force with changing market conditions and revenue outlook, AMS recorded a charge in 2003 of which $4,972 was allocated to the D&IG and was reported as indirect costs and selling expenses for severance and severance-related costs in accordance with SFAS No. 146, Accounting for Costs Associated with Exit or Disposal Activities (“FAS 146”). The 2003 severance costs relate to a reduction in senior level staff and management positions. In addition, during 2002 and 2001, charges of $3,823 and $6,804, respectively, were allocated to the D&IG and reported as indirect costs and selling expenses for severance and severance-related costs. These charges were recorded in accordance with Emerging Issues Task Force 94-3, Liability Recognition for Certain Employee Termination Benefits and Other Costs to Exit an Activity (Including Certain Costs Incurred in a Restructuring). The remaining $724 liability included in accrued compensation and benefits as of December 31, 2003 for severance and severance-related costs is expected to be paid over the next year. During 2002 and 2001, the D&IG recorded charges of $1,133 and $3,956, respectively, for the

closure and consolidation of facilities. During 2003, the D&IG recorded charges of $1,857 related to changes in estimates of the timing and amount of anticipated subtenant rental payments associated with the prior facility restructuring plan and for the closure and consolidation of additional facilities. Of the remaining $3,772 total liability at December 31, 2003, $2,712 represents a noncurrent liability recorded as other long-term obligations for costs to be incurred through 2008.

During the three months ended March 31, 2004 and 2003, the D&IG did not record any charges under FAS 146 for severance or closure of facilities. The remaining liability at March 31, 2004 consisted of $378 for severance and $3,832 for closure of facilities. The facilities liability consists of $1,454 recorded in accrued compensation and benefits and $2,378 recorded as other long-term obligations.

NOTE 8 – COMMITMENTS AND CONTINGENCIES

Lease Commitments

Rental expense of the D&IG totaled $15,824, $12,849 and $14,872 for the years ended December 31, 2003, 2002 and 2001, respectively. The following is a schedule of future minimum lease payments under leases that were assumed by CACI as of December 31, 2003.

2004	$	10,068
2005		9,085
2006		8,350
2007		7,394
2008		6,949

Total	$	49,251

Vredenburg Retention Agreements

In connection with the Vredenburg acquisition (see Note 2), AMS entered into agreements to pay up to approximately $3,600 for continued employment of selected former Vredenburg employees. These amounts will be paid out in installments over a two year period following the acquisition and are being expensed ratably over the periods earned. AMS paid $1,308 during the year ended December 31, 2003. The D&IG’s allocation of this expense was $1,226 which is included in direct costs in the accompanying consolidated 2003 statement of operations.

Indemnification Agreements

The disclosure provisions of Financial Accounting Standards Board Interpretation No. 45, Guarantor’s Accounting and Disclosure Requirements for Guarantees, including Indirect Guarantees of Indebtedness of Others, apply to indemnification agreements that may contingently require a guarantor to make payments. The D&IG enters into licensing arrangements with its customers for the rights to use intellectual property that include a commitment to indemnify the licensee against liability and damages arising from any third-party claims of patent, copyright, trademark or trade secret infringement. The D&IG cannot determine or predict the maximum amount of potential future payments under this type of indemnification because the D&IG would not have adequate information about the nature and scope of any such claim until a claim has been submitted to the D&IG. Third-party claims are subject to contest by the D&IG and dispute resolution procedures specified in the particular contract and payment by the D&IG under such indemnification clauses is generally conditional on the claim. As of December 31, 2003, the D&IG was not aware of any indemnification agreements that would require material payments.

CONSOLIDATED FINANCIAL INFORMATION

The unaudited pro forma condensed consolidated financial information has been prepared by CACI International Inc (“CACI”) and gives effect to the acquisition of certain assets and the assignment of certain liabilities associated with the Defense and Intelligence Group (“D&IG”) of American Management Systems, Inc., (“AMS”) completed on May 1, 2004 for $415 million in cash.

The unaudited pro forma condensed consolidated statement of operations for the twelve months ended June 30, 2003 has been prepared to give effect to the D&IG acquisition as if it had occurred on July 1, 2002. The unaudited pro forma condensed consolidated statement of operations for the nine month period ended March 31, 2004 has been prepared to give effect to the D&IG acquisition as if it had occurred on July 1, 2003. The unaudited pro forma condensed consolidated balance sheet as of March 31, 2004 has been prepared to give effect to the D&IG acquisition as if it has occurred on March 31, 2004.

The pro forma adjustments, which are based on available information and certain assumptions that CACI believes are reasonable under the circumstances, are applied to the historical financial statements of CACI and the D&IG. CACI’s preliminary allocation of the D&IG purchase price is based upon preliminary estimates of the fair value of net assets acquired. Management believes that the preliminary allocation of the purchase price is reasonable, however, in some cases, the final allocation will be based upon an independent valuation that is not yet complete. As a result, the allocation is subject to revision as additional information becomes available, and such revised allocation could differ from the preliminary allocation.

The accompanying unaudited pro forma condensed consolidated financial information should be read in conjunction with the historical financial statements and the notes thereto for CACI and the D&IG. The unaudited pro forma condensed consolidated financial information is provided for informational purposes only and does not purport to represent what CACI’s financial position or results of operations would actually have been had the acquisition occurred on such dates or to project CACI’s results of operations or financial position for any future period.

These pro forma financial statements contain certain costs, including expenses allocated to the D&IG, that CACI’s management does not expect will continue. As a result, actual results may differ significantly from the pro forma information presented herein.

NOTES TO UNAUDITED PRO FORMA

CONDENSED CONSOLIDATED STATEMENTS OF OPERATIONS

The following notes relate to the Unaudited Pro Forma Condensed Consolidated Statements of Operations:

a) To reflect the reported historical operating results of CACI for the year ended June 30, 2003 and the unaudited operating results for the nine months ended March 31, 2004.

b) To reflect the historical results of operations of the D&IG for the twelve month period ended June 30, 2003, consistent with CACI’s fiscal year. The unaudited quarterly statements of operations derived from the audited statements of operations for the years ended December 31, 2002 and 2003 were used.

c) To record estimated amortization expense related to the identifiable intangible assets associated with the acquisition of the D&IG. CACI has retained an outside firm to do an independent appraisal for the allocation of the purchase price related to the acquisition of the D&IG. As this appraisal has not yet been completed, the total allocation, the useful lives, and the method of amortization may change. Based on the most current projections, CACI recorded the following intangible assets: (amounts in thousands).

				Amortization Expense
	Amount		Estimated Useful Life	12 Months Ended June 30, 2003		Nine Months Ended March 1, 2004
Non-compete agreements and contracts related to customer relationships	$	132,000	8 years	$	16,560	$	12,420

d) In conjunction with the acquisition of the D&IG, CACI secured $550 million in financing of which $200 million was in the form of a revolving credit facility that expires in 5 years and $350 million was in the form of a term loan that expires in seven years. The adjustment records the incremental interest expense at an annual average rate of 2.91% related to the additional borrowings of $422.5 million resulting from $415 million in purchase price plus associated financing fees incurred by CACI under its revolving credit facility to finance the D&IG acquisition. The average interest rate used above is the average interest rate we estimate will be applicable based on historical rates. The revolving credit facility will bear interest at adjustable rates. An increase of 1/8% in the interest rate applicable to the revolver would result in an increase in pro forma interest expense of $514,000 and $386,000 and pro forma net income of $26,258,000 and $25,211,000 for the twelve months ended June 30, 2003 and the nine months ended March 31, 2004, respectively.

e) To recognize federal and state income taxes at combined rates of 37.7% and 38.2% for the twelve months ended June 30, 2003 and the nine months ended March 31, 2004, respectively, which reflects CACI’s overall tax rate for the corresponding periods.

f) To reflect the sale of Karcher Group Incorporated (“Karcher”) previously operated by the D&IG. Karcher was acquired on August 1, 2003 by AMS in connection with AMS’ acquisition of R.M. Vrendenburg & Co. CACI sold Karcher in May 2004, as it was not complimentary to the business operated by CACI.

g) To reflect the elimination of intercompany revenue and expense between CACI and the D&IG.

h) To reflect bank financing fee amortization as follows (amounts in thousands):

	Amount		Estimated Term	Interest Expense
				12 Months Ended June 30, 2003		Nine Months Ended March 31, 2004
Term loan	$	4,800	7 years	$	686	$	514
Revolving credit facility		2,700	5 years		540		405
	$	7,500		$	1,226	$	919

CACI INTERNATIONAL INC

NOTES TO UNAUDITED PRO FORMA

CONDENSED CONSOLIDATED BALANCE SHEET

The following notes relate to the Unaudited Pro Forma Condensed Consolidated Balance Sheet.

a) To reflect the historical unaudited financial position of CACI.

b) To reflect the historical unaudited financial position of the D&IG.

c) The D&IG acquisition has been accounted for under the purchase method pursuant to the provisions of Statement of Financial Accounting Standards No. 141, Business Combinations. Accordingly, the identifiable net tangible and separately identifiable intangible assets acquired and liabilities assumed were recognized at their estimated fair values as of the date of the combination. The pro forma adjustments herein are based on management’s preliminary estimates of fair value. The final allocation of the purchase price, when completed, may differ materially from the preliminary purchase price allocation herein.

Borrowings utilized for the D&IG are as follows (amounts in thousands):

Purchase Price	$	415,000
Financing Costs		7,500
Total borrowings	$	422,500

The total consideration paid for the acquisition was obtained primarily through borrowings under CACI’s credit facilities.

The preliminary allocation of the purchase price is as follows (amounts in thousands):

Net estimated fair value of assets purchased	$	88,039
Goodwill		235,621
Estimated intangible assets		132,000
Loss reserve on contract		(29,500	) see footnote (d)
Reduction in value of developed computer software		(4,160	) see footnote (d)
Deferred income taxes		(7,000	) see footnote (e)
	$	415,000

d) The D&IG was capitalizing software to be sold to both Federal and Civilian customers under Statement of Financial Accounting Standards No. 86, Accounting for the Cost of Computer Software to Be Sold, Leased, or Otherwise Marketed. Currently, only one customer is contractually obligated to purchase this on-going developed software. While CACI’s management intends to complete the development of this software for the customer, CACI does not plan to continue to market this software. As a result, no value was allocated to the capitalized software as part of the purchase and therefore, $4.16 million was removed from Developed Computer Software. In addition, the change in management’s intent regarding the software product changes the accounting guidance to AICPA Statement of Position No. 81-1, Accounting for Performance of Construction, Type and Certain Production-Type Contracts (“SOP 81-1”). When applying percentage of completion accounting using SOP 81-1, the contract is expected to be in a significant loss position. As a result, $29.5 million has been recorded as a liability in Other Accrued Expenses, based on the most recent estimate-to-complete analysis available.

e) As part of CACI’s acquisition of the D&IG business, the Company acquired the stock of R.M. Vredenburg & Co. (“Vredenburg”). For book purposes, CACI is required to amortize intangible assets, however, for tax purposes, the amortization is not deductible. This results in a deferred tax liability estimated to be approximately $7.0 million.

24

f) In securing the $550 million in financing (see Note d of the Unaudited Pro Forma Condensed Consolidated Statements of Operations) CACI incurred $7.5 million of debt financing fees which have been recorded as Other Assets on the balance sheet. These costs will be amortized over the terms of the related credit facilities.

g) To adjust Other Intangible Assets and Goodwill related to the AMS acquisition of Vredenburg. These assets have been subsequently reevaluated with the purchase of D&IG by CACI. The chart below reconciles the change in Other Intangible Assets and Goodwill:

	Other Intangible Assets			Goodwill
Purchase price allocation	$	132,000		$	235,621
Historical D&IG		(13,251	)		(26,892	)
Pro forma adjustment	$	118,749		$	208,729

2.3 Assumption of Specified Obligations. At the Closing, Acquisition Sub shall agree to assume and perform after the Closing when and as they become due the obligations and liabilities of Arrow related to the Business, including the following (the “Dagger Obligations”):

2.3.1 Arrow’s accounts payable, accrued expenses and deferred revenue relating to the Business through the Closing Date, such amounts to be calculated in a manner consistent with the Dagger Balance Sheet for the Reported Business, except that such amounts shall be for the Business.

2.3.2 Arrow’s obligations after the Closing under the Dagger Engagements, the Dagger Completed Engagements, the Dagger Contracts and the Dagger Leases; and

2.3.3 Arrow’s liabilities to Dagger Employees that are not covered by insurance held by Arrow or Crossbow, whether or not such persons actually become employees of Acquisition Sub.

Except for the Dagger Obligations, Acquisition Sub is assuming no liabilities or obligations of Arrow in connection with this transaction, including (a) any liability or obligation of Arrow to any of its Subsidiaries or Affiliates (b) any liability or obligation of Arrow to any director, officer, employee or other agent of Arrow (other than the Dagger Employees), (c) any liability or obligation of Arrow under any contract, agreement or arrangement relating to the Business or the conduct thereof other than the Dagger Engagements, the Dagger Completed Engagements, the Dagger Contracts and the Dagger Leases, (d) any trade or practice liabilities or

obligations of Arrow, (e) any liability or obligation of Arrow to any current, former or deceased employee of Arrow or any of its Subsidiaries or Affiliates (other than the Dagger Subsidiaries), other than the Dagger Employees, (f) any liability or obligation of Arrow or any of its Subsidiaries (other than the Dagger Subsidiaries) under any Employee Benefit Plan, or (g) any liability of Arrow for Taxes. Without limiting the generality of the foregoing, Arrow and its Subsidiaries (exclusive of the Dagger Subsidiaries) shall be solely responsible for payment and performance of all liabilities, obligations and amounts at any time owing by any of them before or after the Closing Date, whether direct or indirect, fixed or contingent, known or unknown, other than the Dagger Obligations.

The parties to this Agreement intend that any Liability of Arrow that is based on, or arises out of, facts or circumstances that existed prior to the Closing Date and is not primarily related to the Business shall not be assumed by Acquisition Sub and shall not be or become a Dagger Obligation except as expressly set forth herein. Without limiting the generality of the foregoing, no Liability of Arrow that is not primarily related to the Business shall be allocated or divided between the Business, on the one hand, and the business and operations being acquired by Crossbow and Merger Sub, on the other hand, unless expressly provided herein.

The parties understand that Arrow will not assume the liabilities of the Dagger Subsidiaries, but that such liabilities shall be retained by the Dagger Subsidiaries.

2.4 Purchase Price. The purchase price (the “Purchase Price”) to be paid by Acquisition Sub for the Dagger Assets shall be Four Hundred Fifteen Million Dollars ($415,000,000), subject to adjustment as provided below in Section 2.8. The payment of the Purchase Price shall be made in immediately available funds wired to one or more accounts designated by Arrow or by such other method as may be agreed by Arrow and Acquisition Sub.

2.5 Closing. The closing of the purchase and sale of the Dagger Assets (the “Closing”) shall take place at the offices of Arnold & Porter LLP in McLean, Virginia, commencing at 9 a.m. local time on such date that is the first business day immediately following the satisfaction or waiver of all conditions to the obligations of the parties to consummate the transactions contemplated hereby (the “Closing Date”).

2.6 Instruments of Transfer. Arrow shall effect the transfer of the Dagger Assets and the Dagger Obligations to Acquisition Sub at the Closing by such bills of sale, assignments, assumptions and other instruments of transfer as Acquisition Sub or its

counsel deem necessary or appropriate to transfer full legal and beneficial title to the Dagger Assets free and clear of all Security Interests whatsoever except Permitted Encumbrances, and to transfer full responsibility for the Dagger Obligations. As appropriate, such documents shall contain customary warranties and covenants of title and shall be in form and substance acceptable to Acquisition Sub and its counsel.

2.7 Additional Actions. At any time and from time to time after the Closing Date, (a) at the reasonable request of Acquisition Sub, Arrow shall execute and deliver to Acquisition Sub such other instruments of transfer, conveyance, assignment and confirmation and take such action as Acquisition Sub may reasonably deem necessary or desirable in order to transfer, convey and assign to Acquisition Sub and to confirm Acquisition Sub’s title to any of assets primarily utilized in connection with the performance and technical and administrative support of the Business inadvertently left in the control or possession of Arrow and all instruments, undertakings or other documents and take such other action as Acquisition Sub may reasonably deem necessary or desirable in order to have Arrow fully assume and be liable for any Liabilities of Arrow that are not Dagger Obligations and that were inadvertently assumed by Acquisition Sub, and (b) at the reasonable request of Arrow, Acquisition Sub shall execute and deliver to Arrow such other instruments of transfer, conveyance, assignment and confirmation and take such action as Arrow may reasonably deem necessary or desirable in order to transfer, convey and assign to Arrow and to confirm Arrow’s title to any of the Excluded Assets inadvertently transferred to Acquisition Sub and all instruments, undertakings or other documents and take such other action as Arrow may reasonably deem necessary or desirable in order to have Acquisition Sub fully assume and be liable for any Dagger Obligations that were inadvertently retained by Arrow.

Prior to the first anniversary of the Closing Date, if either Crossbow or Acquisition Sub shall determine that an asset or liability of the Business was inappropriately included in or excluded from the definition of either the Dagger Assets or the Dagger Obligations, the party that makes such determination shall so advise the other party and Crossbow and Acquisition Sub shall in good faith endeavor to reach agreement with respect to such asset or liability.

If a dispute arises under this Section 2.7, then within three (3) business days after a written request by either party, Federal’s President and Crossbow’s President of U.S. Operations shall promptly confer to resolve the dispute. If such persons cannot resolve such dispute, or either one of them determines that they are not making reasonable progress toward resolution of the dispute within the five (5) business day period immediately following the delivery of the written notice described above, then such dispute shall be settled by arbitration in the City of New York in

accordance with the Rules of the American Arbitration Association by a single arbitrator, who shall be an attorney expert in the area of mergers and acquisitions, selected by Crossbow and Acquisition Sub (or, if the parties are unable to agree on the arbitrator within five (5) business days of commencing arbitration, such an expert selected by the Association). Judgment upon the award rendered under any such arbitration may be entered in any Court having jurisdiction thereof.

2.8 Adjustment to Purchase Price

2.8.1 Preparation of Closing Balance Sheet. As soon as reasonably practicable after the Closing Date (but not later than 60 days thereafter), Arrow shall prepare or cause to be prepared and shall deliver to Acquisition Sub a Closing Balance Sheet for the Business as of the opening of business on the Closing Date (the “Closing Balance Sheet”). The Closing Balance Sheet shall be prepared in accordance with United States Generally Accepted Accounting Principles (“GAAP”).

2.8.2 Review of Closing Balance Sheet. Acquisition Sub, upon receipt of the Closing Balance Sheet, shall (a) review the Closing Balance Sheet and (b) to the extent Acquisition Sub may deem necessary, make reasonable inquiry of Arrow and its accountants, relating to the preparation of the Closing Balance Sheet. Acquisition Sub and its employees and advisors shall have full access upon prior written notice and during normal business hours to the books, papers and records of Arrow and its accountants (if any are used), relating to the preparation of the Closing Balance Sheet in connection with such inquiry and the preparation of any objections thereto (“Objections”). The Closing Balance Sheet shall be binding and conclusive upon, and deemed accepted by, Acquisition Sub unless Acquisition Sub shall have notified Arrow in writing of any Objections thereto within 30 days after receipt of the Closing Balance Sheet. Acquisition Sub shall make the Dagger Employees and books and records of the Business available to Arrow as necessary for Arrow to prepare the Closing Balance Sheet.

2.8.3 Disputes. In the event of Objections, Arrow shall have 20 days to review and respond to such Objections, and Acquisition Sub and Arrow shall attempt to resolve the differences underlying such Objections within 20 days following completion of Arrow’s review of such Objections. Disputes between Acquisition Sub and Arrow which cannot be resolved by them within such 20-day period shall be referred no later than such 20th day for decision to PricewaterhouseCoopers LLP or to a nationally recognized independent public accounting firm mutually selected by the Acquisition Sub and Arrow

(the “Auditor”) (which firm shall not be any of (a) the independent public accountants of Parent, Federal and Acquisition Sub, (b) the independent public accountants used by Arrow prior to the Closing Date and (c) the independent public accountants of Crossbow), who shall act as arbitrator and determine, based solely on presentations by Acquisition Sub and Arrow and only with respect to the remaining differences so submitted, whether and to what extent, if any, the Closing Balance Sheet requires adjustment. The Auditor shall deliver its written determination to Acquisition Sub and Arrow no later than the 30th day after the remaining differences underlying such Objections are referred to the Auditor, or such longer period of time as the Auditor reasonably determines is necessary. The Auditor’s determination shall be conclusive and binding upon the parties. The fees and disbursements of the Auditor shall be allocated equally between Acquisition Sub and Arrow. Acquisition Sub and Arrow shall make readily available to the Auditor all relevant information, books and records and any work papers relating to the Closing Balance Sheet and all other items reasonably requested by the Auditor. In no event may the Auditor’s resolution of any difference be for an amount which is outside the range of Acquisition Sub’s and Arrow’s disagreement.

2.8.4 Final Closing Balance Sheet. The Closing Balance Sheet shall become final and binding upon the parties upon the earliest of (a) Acquisition Sub’s failure to object thereto within the period permitted under Section 2.8.2, (b) the agreement between Acquisition Sub and Arrow with respect thereto and (c) the decision by the Auditor with respect to any disputes under Section 2.8.3. The Closing Balance Sheet, as adjusted pursuant to the agreement of the parties or decision of the Auditor, when final and binding is referred to herein as the “Final Closing Balance Sheet.”

2.8.5 Adjustments to the Purchase Price. As soon as practicable (but not more than five business days) after the date on which the Final Closing Balance Sheet shall have been determined in accordance with this Section 2.8, (a) Arrow shall pay to Acquisition Sub in immediately available funds the amount, if any, by which the Net Tangible Asset Value on the Final Closing Balance Sheet is less than $50,000,000 (Fifty Million Dollars), or (b) Acquisition Sub shall pay to Arrow in immediately available funds the amount, if any, by which the Net Tangible Asset Value on the Final Closing Balance Sheet is greater than $60,000,000 (Sixty Million Dollars); provided, that no payment made pursuant to this Section 2.8.5 shall exceed the amount of $10,000,000 (Ten Million Dollars). Any payment made pursuant to this Section 2.8.5 shall constitute an immediate adjustment of the Purchase Price in such amount. For the avoidance of doubt, the existence or possible existence of any adjustment to the Purchase Price, Objection, pendency or resolution of any dispute pursuant to this Section 2.8 or any issue pertaining to

the Closing Balance Sheet shall not in any way impact, hinder, prevent or otherwise delay Crossbow’s obligation to consummate the transactions contemplated in the Merger Agreement.

6.1.2 No Solicitation. Each of Crossbow and Parent agrees that prior to the one-year anniversary of the date hereof, neither it nor any of its Subsidiaries nor any of their respective officers, directors, advisors, agents, accountants, consultants, employees, investment bankers and legal counsel (collectively, “Representatives”) shall directly or indirectly: (i) solicit, initiate, or knowingly encourage, facilitate or induce any inquiry with respect to, or the making, submission or announcement of, any acquisition proposal to purchase all or substantially all of the Business or the business and operations being acquired by Crossbow and Merger Sub, as the case may be; (ii) participate in any discussions or negotiations regarding, or furnish to any Person any nonpublic information with respect to, or take any other action to facilitate any inquiries or the making of any proposal that constitutes or may reasonably be expected to lead to, any such acquisition proposal; (iii) engage in discussions with any Person with respect to any such acquisition proposal, except as to the existence of these provisions; (iv) approve, endorse or recommend any such acquisition proposal; or (v) enter into any letter of intent or similar document or any contract agreement or commitment contemplating or otherwise relating to any acquisition proposal or any transaction contemplated thereby. Crossbow or Parent, as the case may be, shall immediately terminate, and shall cause each of its Subsidiaries and its and their Representatives to immediately terminate, all activities, discussions or negotiations, if any, with any third party with respect to, or any that could reasonably be expected to lead to or contemplate the possibility of, an acquisition proposal. Crossbow or

Parent, as the case may be, shall promptly request that each person which has heretofore executed a confidentiality agreement with Crossbow or Parent, as the case may be, or any of its Affiliates or Subsidiaries or any of its or their Representatives with respect to such Person’s consideration of a possible acquisition proposal to promptly return or destroy (which destruction Crossbow or Parent, as the case may be, shall request be certified in writing by such person) all confidential information heretofore furnished by Crossbow or Parent, as the case may be, or any of its Affiliates or Subsidiaries or any of its or their Representatives to such person or any of its Affiliates or Subsidiaries or any of its or their Representatives.

6.2 Transition of Employees and Consultants. Within five (5) days prior to Closing, Arrow shall provide an updated Employee List, containing the name of each employee of the Business, and each person’s level title, role, starting date, annual salary and target bonus, together with a listing of the level of security clearance for such employees. Parent, Federal, Acquisition Sub or one of their Affiliates shall offer to employ or retain as a consultant effective as of 12:00 A.M. on the date immediately following the Closing Date each Dagger Employee and each Dagger Consultant employed by (or providing consulting to) Arrow as of the Closing Date. Arrow shall cooperate with Parent to facilitate meetings (to occur at mutually agreed upon times and locations) between (a) Dagger Employees and Dagger Consultants and (b) representatives of Parent, Federal and Acquisition Sub, so as to permit Parent, Federal and Acquisition Sub to discuss with such Dagger Employees and Dagger Consultants employment or a consulting relationship, as the case may be, with Acquisition Sub, Federal, Parent, a Dagger Subsidiary or one of their Affiliates (the “Acquisition Group”) as well as other matters relating to planning for the post-Closing integration of the Business into the Acquisition Group. Subject to applicable Legal Requirements, Arrow shall make a good faith effort to encourage the Dagger Employees and the Dagger Consultants to accept employment or a consulting relationship, as the case may be, with the Acquisition Group, and, as of 11:59 p.m. on the Closing Date, shall terminate the employment or consulting relationship of all Dagger Employees and Dagger Consultants, as the case may be. All Dagger Employees and Dagger Consultants employed by (or providing consulting services to) a Dagger Subsidiary shall, subject to Section 6.2.2, retain their employment or consulting relationship with such Dagger Subsidiary immediately following the Closing Date.

Notwithstanding the foregoing, all visits to any office of any Dagger Company will be coordinated and conducted so as to not be disruptive to the operations of such Dagger Company and to preserve the confidentiality of the Transaction. In addition, Arrow will facilitate meetings between Parent, Federal and Acquisition Sub and the Dagger Companies’ significant customers so as to permit Parent, Federal and Acquisition Sub to discuss the announced Transaction with such customers.

6.5 Public Disclosure. Immediately following the execution of this Agreement, Parent, Arrow and Crossbow each shall disseminate the press releases attached as Exhibit B. Except as otherwise required by law (including disclosures necessary or advisable to ensure compliance with applicable securities laws), no party hereto shall make any other public disclosure of information regarding the transactions contemplated herein prior to the Closing without the consent of each of Parent, Arrow and Crossbow, each of which consents shall not be unreasonably withheld or delayed. The parties acknowledge that Parent and Crossbow have previously executed a Confidentiality Agreement dated as of December 16, 2003 and that Parent and Arrow have previously executed a letter agreement regarding confidentiality dated January 7, 2004 (collectively, the “Confidentiality Agreements”), which Confidentiality Agreements shall continue in full force and effect in accordance with their respective terms notwithstanding any termination or abandonment of this Agreement or the Merger.

6.6 Further Assurances

6.6.1 Generally. Subject to terms and conditions herein provided and to the fiduciary duties of the board of directors and officers or representatives of any party, each of the parties agrees to use its commercially reasonable efforts to take, or cause to be taken, all action and to do, or cause to be done, all things necessary, proper or advisable under applicable laws and regulations to consummate and make effective this Agreement and the transactions contemplated hereby. In case at any time any further action, including,

without limitation, the obtaining of waivers and consents under any agreements, material contracts or leases and the execution and delivery of any licenses or sublicenses for any software, is necessary, proper or advisable to carry out the purposes of this Agreement, the proper officers and directors or representatives of each party to this Agreement are hereby directed and authorized to use commercially reasonable efforts to effectuate all required action, except to the extent that greater efforts are required pursuant to Section 6.12.

6.6.2 Novation of Contracts; Subcontracting; Maintenance of Corporate Existence of Arrow. Each party agrees to use commercially reasonable efforts to effect the novation of, or change of name with respect to, each Dagger Government Contract that may require novation or a change of name under its terms or under applicable laws or regulations, and further agrees to provide all documentation necessary to effect each such novation or change of name, including all instruments, certifications, requests, legal opinions, audited financial statements, and other documents required by Part 42 of the Federal Acquisition Regulation to effect a novation of any contract with the United States Government. In particular and without limiting the generality of the foregoing, Arrow shall continue to communicate with responsible officers of the United States Government from time to time as may be appropriate and permissible, to request speedy action on any and all requests for consent to novation or change of name. Notwithstanding the foregoing, Arrow makes no representation or warranty that any such novation of, or change of name with respect to, any Dagger Government Contract will in fact be obtained.

With respect to each Dagger Government Contract that requires novation or a change of name, prior to such novation or change of name, Arrow will engage Acquisition Sub as subcontractor under such contract, agree to take all reasonable instruction from Acquisition Sub as Arrow’s conduct under such contract and promptly pay to Acquisition Sub the full amount of its receipts under such contract.

Arrow shall not terminate its existence until all of the Government Contracts of the Dagger Companies have either terminated or duly transferred to Acquisition Sub.

6.7 Tax Matters

6.7.1 Allocation of Purchase Price. Acquisition Sub and Arrow agree that the Purchase Price and the liabilities of Arrow assumed by Acquisition Sub to which the Dagger Assets are subject (plus other relevant items) will be

allocated to the Dagger Assets for all purposes (including Tax and financial accounting purposes) as shown on Schedule 6.7.1. Acquisition Sub and Arrow shall have prepared such allocation schedule in accordance with Code section 1060 and the Treasury regulations thereunder. Parent, Acquisition Sub and Arrow will file all Tax Returns (including amended returns and claims for refund) and information reports in a manner consistent with such allocation schedule.

6.7.2 Responsibility for Filing Tax Returns for Periods through Closing Date. Arrow shall include the income of the Dagger Subsidiaries (including any deferred items triggered into income by Reg. 1.1502-13 and any excess loss account taken into income under Reg. 1.1502-19) on Arrow’s consolidated federal income Tax Returns for all periods through the Closing Date and pay any federal income Taxes attributable to such income. For all taxable periods ending on or before the Closing Date, Arrow shall cause the Dagger Subsidiaries to join in Arrow’s consolidated federal income tax return and, in jurisdictions requiring separate reporting from Arrow, to file separate company state and local income tax returns. All such Tax Returns shall be prepared and filed in a manner consistent with prior practice, except as required by a change in applicable law.

6.7.3 Audits. Arrow shall allow Parent and its counsel to participate, at Parent’s expense, in any audit of Arrow’s consolidated federal income Tax Returns to the extent that such returns related to any Dagger Subsidiary. Arrow shall not settle any such audit in a manner which would adversely affect any Dagger Subsidiary after the Closing Date without the prior written consent of Parent, which consent shall not unreasonably be withheld.

6.7.4 Cooperation on Tax Matters

(a) Acquisition Sub and Arrow shall cooperate fully, as and to the extent reasonably requested by any party, in connection with the filing of Tax Returns and any audit, litigation or other proceeding with respect to Taxes. Such cooperation shall include the retention and (upon another party’s request) the provision of records and information which are reasonably relevant to any such audit, litigation or other proceeding and making employees available on a mutually convenient basis, at no cost to any Parent, Federal or Acquisition Sub, to provide additional information and explanation of any material provided hereunder.

therewith; (d) the defending of any suits, claims, actions, investigations or proceedings, whether judicial or administrative, challenging this Agreement or the consummation of the transactions contemplated hereby, including seeking to have any stay or temporary restraining order entered by any court or other Governmental Entity vacated or reversed (it being understood that the costs of such defense shall be borne equally by Parent and Arrow); and (e) the execution or delivery of any additional instruments necessary to consummate the transactions contemplated by, and to fully carry out the purposes of, this Agreement.

This Agreement, and such other agreements among the parties contemplated by or referred to herein (including the Ancillary Agreements) may not be amended, except in a writing, signed by all parties to this Agreement, whether or not such party to this Agreement is a party to such other agreement.

8.11 Non-Survival of Representations, Warranties and Covenants.

Except as set forth on Schedule A1, Arrow is duly qualified or licensed to do business as a foreign corporation and is in good standing in all jurisdictions in which the character of the properties owned or held under lease by it or the nature of the business transacted by it makes qualification necessary, except where failure to be so qualified would be immaterial.

A4 Financial Statements. Attached as Schedule A4 are a consolidated balance sheet for the Reported Business as of December 31, 2003 and statement of operations for the year then ended. Collectively, the financial statements referred to in the immediately preceding sentence are sometimes referred to herein as the “Dagger Financial Statements” and the Reported Business’s balance sheet as of December 31, 2003 is referred to herein as the “Dagger Balance Sheet.” The Dagger Balance Sheet (including any related notes) fairly presents in all material respects the Reported Business’s financial position as of its date, and the statement of operations included in the Dagger Financial Statements (including any related notes) fairly presents in all material respects the Reported Business’s results of operations for the period therein set forth, each having been prepared and compiled in accordance with GAAP, it being understood that the Dagger Financial Statements have been prepared on a pro forma basis, reflecting the separation of the Reported Business from Arrow. “Reported Business” means the “Defense and Intelligence Group” of Arrow (excluding any business performed in Canada by a Dagger Company) together with the business of the Dagger Subsidiaries (including any federal civilian, state and local engagements of such Dagger Subsidiaries) on a consolidated basis. To the Knowledge of Arrow, there are no significant deficiencies or material

weaknesses in the design or operation of Arrow’s internal controls which could adversely affect Arrow’s ability to record, process, summarize and report financial data relating to the Business. To the Knowledge of Arrow, there is no fraud relating to the Business, whether material or not, that involves management or other employees who have a significant role in Arrow’s internal controls.

A5 Absence of Material Adverse Changes. Except as set forth on Schedule A5, since December 31, 2003 (the “Balance Sheet Date”), Arrow has not suffered a Dagger Material Adverse Effect, and, to the Knowledge of Arrow, there has not occurred or arisen any event, condition or state of facts of any character that would reasonably be expected to result in a Dagger Material Adverse Effect.

A6 Absence of Undisclosed Liabilities. Except as set forth on Schedule A6, the Reported Business has no Liabilities that are not fully reflected or provided for on, or disclosed in the notes to, the balance sheets included in the Dagger Financial Statements, except (a) Liabilities incurred in the ordinary course of business since the Balance Sheet Date, none of which individually or in the aggregate has had or could reasonably be expected to be material, (b) Liabilities permitted or contemplated by this Agreement, (c) Liabilities not within the Knowledge of Arrow that are not required to be disclosed by Arrow under GAAP, (d) Liabilities for future performance under contracts, and (e) Liabilities expressly disclosed on the Schedules delivered hereunder.

A7 Compliance with Applicable Law, Charter and By-Laws. Each Dagger Company has all requisite licenses, permits and certificates from all Governmental Entities necessary to conduct the Business as currently conducted, and to own, lease and operate their respective properties used in the Business in the manner currently held and operated (collectively, “Permits”), except as set forth on Schedule A7 and except for any Permits the absence of which, either singly or in the aggregate, is immaterial and would not reasonably be expected to have a material effect or prevent or materially delay the Closing. All of such Permits are in full force and effect. Each Dagger Company is in compliance in all material respects with the terms and conditions related to such Permits. There are no proceedings in progress, pending or, to the Knowledge of Arrow, threatened, which may result in revocation, cancellation, suspension, or any materially adverse modification of any of such Permits. The Business is not being, and has not been, conducted in violation of any applicable law, statute, ordinance, regulation, rule, judgment, decree, order, Permit, concession, grant or other authorization of any Governmental Entity. No Dagger Company is in default or violation of any provision of its charter documents or its by-laws where such default or violation is material.

A8 Litigation and Proceedings. Except for any claim, action, suit or proceeding set forth on Schedule A8, (a) there is no investigation by any Governmental Entity with respect to the Business pending or, to the Knowledge of Arrow, threatened, nor has any Governmental Entity notified any Dagger Company an intention to conduct the same; (b) there is no claim, action, suit, arbitration or proceeding pending or, to the Knowledge of Arrow, threatened against or involving any Dagger Company and involving the Business, any of the Dagger Assets or any of the assets or properties of any Dagger Subsidiary, at law or in equity, or before any arbitrator or Governmental Entity; and (c) there are no judgments, decrees, injunctions or orders of any Governmental Entity or arbitrator outstanding against any Dagger Company (i) affecting the Business, the Dagger Assets or the assets or properties of any Dagger Subsidiary or (ii) which create a Dagger Obligation in each case to the extent that the resolution of such dispute or claim will be binding on Acquisition Sub or a Dagger Subsidiary or give rise to a Dagger Obligation.

A9 Tax Matters

A9.1 Filing of Returns. Each Dagger Subsidiary has timely filed all Tax Returns that it was required to file, and Arrow has timely filed all Tax Returns with respect to the Business that it was required to file in each case taking into account all validly obtained extensions. All such Tax Returns were correct and complete in all material respects. All Taxes owed (whether or not shown on any Tax Return) by any Dagger Subsidiary, or by Arrow with respect to the Business, have been paid. To the extent that any Dagger Subsidiary has any Liability under Treasury Regulation Section 1.1502-6 (or any similar provision of state, local or foreign law) for Taxes due and payable by Arrow or any member of Arrow’s consolidated, combined, affiliated or unitary group, such Taxes have been paid. No Dagger Subsidiary is currently the beneficiary of any extension of time within which to file any Tax Return. No claim relating to the Business has ever been made by an authority in a jurisdiction where any Dagger Company does not file Tax Returns that it is or may be subject to taxation by that jurisdiction, which claims have not been resolved. There are no Security Interests on any of the Dagger Assets or on any assets of any Dagger Subsidiary that arose in connection with any failure (or alleged failure) to pay any Tax, other than Permitted Encumbrances.

A9.2 Payment of Taxes. Each Dagger Subsidiary, and with respect to the Business, Arrow, has withheld and paid all Taxes required to have been withheld and paid in connection with amounts paid or owing to any employee, independent contractor, creditor, stockholder or other third party with respect to the Business.

A9.3 Assessments or Disputes. To the Knowledge of Arrow, no Tax authority proposes to assess any additional Taxes upon any Dagger Subsidiary or upon Arrow with respect to the Business, in each case for any period for which Tax Returns have been filed. Except as described in written materials delivered to Acquisition Sub, there is no dispute or claim concerning any Tax Liability of any Dagger Subsidiary, or of Arrow with respect to the Business, either (a) claimed or raised in writing by any Tax authority or (b) to the Knowledge of Arrow, otherwise claimed or raised by any Tax authority, in each case to the extent that resolution of such dispute or claim will be binding upon Acquisition Sub or a Dagger Subsidiary after the Closing. Except to the extent otherwise described in written materials delivered to Acquisition Sub, Arrow has delivered to Acquisition Sub, or made available for review by Acquisition Sub, correct and complete copies of all income Tax Returns, examination reports and statements of deficiencies that were (i) filed by, assessed against or agreed to by or with respect to any Dagger Subsidiary and (ii) expressly included within a written due diligence request made by Acquisition Sub prior to the date hereof.

A9.4 Waiver of Statute of Limitations. No Dagger Company has waived any statute of limitations in respect of Taxes that relate to the Business or agreed to any extension of time with respect to a Tax assessment or deficiency that relates to the Business, in each case to the extent that resolution of such assessment or deficiency will be binding upon Acquisition Sub or a Dagger Subsidiary after the Closing.

A9.5 Collapsible Corporations, Golden Parachutes, Real Property Holding Corporations. No Dagger Subsidiary has filed a consent under Code section 341(f) concerning collapsible corporations. Except as set forth on Schedule A9.5, no Dagger Subsidiary is a party to any agreement, contract, arrangement or plan that has resulted or would result, separately or in the aggregate, in the payment of (a) any “excess parachute payment” within the meaning of Section 280G of the Code (or any corresponding provision of state, local or foreign Tax law) and (b) any amount that will not be fully deductible as a result of Section 162(m) of the Code (or any corresponding provision of state, local, or foreign Tax law). No Dagger Subsidiary has been a United States real property holding corporation within the meaning of Code section 897(c)(2) during the applicable period specified in Code section 897(c)(1)(A)(ii). No Dagger Subsidiary is a party to any Tax allocation or sharing agreement under which such Dagger Subsidiary will have any liability after the Closing. No Dagger Subsidiary (A) has been a member of an Affiliated Group filing a consolidated federal income Tax Return (other than a group the common parent of which was Arrow) or (B) has any Liability for the Taxes of any Person (other than a member of an Affiliated Group the common parent of

which was Arrow) under Treasury Regulation Section 1.1502-6 (or any similar provision of state, local, or foreign law). Prior to the applicable due date (including extensions), Arrow shall file a consolidated federal income tax return with the Dagger Subsidiaries, among other Persons, for the taxable year immediately preceding the current taxable year.

A9.6 Unpaid Taxes. The unpaid Taxes of the Dagger Companies for which Acquisition Sub and/or the Dagger Subsidiaries shall be liable (a) did not, as of the date of the Dagger Balance Sheet, exceed the reserve for Tax liability (rather than any reserve for deferred Taxes established to reflect timing differences between book and Tax income) reflected in the Dagger Balance Sheet and (b) do not exceed that reserve as adjusted for the passage of time through the Closing Date in accordance with the past custom and practice of the Dagger Companies in filing their Tax Returns.

A9.7 Unclaimed Property. No Dagger Company has any assets that may constitute unclaimed property under applicable law. The Dagger Companies have complied in all material respects with all applicable unclaimed property laws. Without limiting the generality of the foregoing, the Dagger Companies have established and followed procedures to identify any unclaimed property and, to the extent required by applicable law, remit such unclaimed property to the applicable governmental authority. The records of the Dagger Companies are adequate to permit a governmental agency or authority or other outside auditor to confirm the foregoing representations.

A9.8 No Changes in Accounting, Closing Agreement, Installment Sale. No Dagger Subsidiary will be required to include any item of income in, or exclude any item of deduction from, taxable income for any taxable period (or portion thereof) beginning after the Closing Date as a result of any (a) change in method of accounting for a taxable period ending on or prior to the Closing Date under Code section 481(c) (or any corresponding or similar provision of state, local or foreign income Tax law), other than any such change required as a result of the transactions occurring at Closing pursuant to this Agreement; (b) “closing agreement” as described in Code section 7121 (or any corresponding or similar provision of state, local or foreign income Tax law) executed on or prior to the Closing Date; (c) deferred intercompany gain or any excess loss account described in Treasury Regulations under Code section 1502 (or any corresponding or similar provision of state, local or foreign income Tax law); (d) installment sale or open transaction disposition made on or prior to the Closing Date; or (e) prepaid amount received on or prior to the Closing Date.

A22.1 Generally. Each Dagger Material Contract, and to the Knowledge of Arrow each other Dagger Engagement, that is a Government Contract (each an “Active Government Contract”) is listed on Schedule 2.1.1 and identified as a Government Contract. Each Dagger Completed Engagement that is or was a

Government Contract is referred to herein as a “Completed Government Contract.” Also listed on Schedule 2.1.1 and identified as a Government Bid is each outstanding quotation, bid or proposal for a Government Contract involving the Business. Listed on Schedule A22.1 is each Active Government Contract under which to the Knowledge of Arrow, any Dagger Company currently is experiencing, or is likely to experience, material cost, schedule, technical or quality problems.

A22.2 Bids and Awards. To the Knowledge of Arrow, (i)each Active Government Contract and each Completed Government Contract (collectively, the “Dagger Government Contracts”) was legally awarded, (ii)no such Active Government Contract (or, where applicable, the prime contract with the United States Government under which such Government Contract was awarded) is the subject of bid or award protest proceedings, and (iii)no such Active Dagger Government Contract (or, where applicable, the prime contracts with the United States Government under which such Government Contract was awarded) is reasonably likely to become the subject of bid or award protest proceedings. To the Knowledge of Arrow, no facts exist which could give rise to a material claim for price adjustment under the Truth in Negotiations Act or to any other request for a material reduction in the price of any Dagger Government Contracts.

A22.3 Compliance with Law and Regulation and Contractual Terms; Inspection and Certification. Each Dagger Company has complied in all material respects with all statutory and regulatory requirements pertaining to the Dagger Government Contracts to which it is a party, including the Armed Services Procurement Act, the Federal Procurement and Administrative Services Act, the Federal Acquisition Regulation (the “FAR”), the FAR cost principles and the Cost Accounting Standards. To the Knowledge of Arrow, each Dagger Company has complied in all material respects with all terms and conditions, including (but not limited to) all clauses, provisions, specifications, and quality assurance, testing and inspection requirements of the Dagger Government Contracts, whether incorporated expressly, by reference or by operation of law. To the Knowledge of Arrow, all facts set forth in or acknowledged by any representations, certifications or disclosure statements made or submitted by or on behalf of any Dagger Company in connection with any Dagger Government Contracts and its quotations, bids and proposals for Government Contracts were current, accurate and complete in all material respects as of the date of their submission. To the Knowledge of Arrow, each Dagger Company has complied in all material respects with all applicable representations, certifications and disclosure requirements under all Dagger Government Contracts and each of its quotations, bids and proposals for Government Contracts. Each Dagger Company has developed and implemented a government contracts compliance program which includes

corporate policies and procedures to ensure compliance with applicable government procurement statutes, regulations and contract requirements. To the Knowledge of Arrow, no facts exist which could reasonably be expected to give rise to liability to any Dagger Company under the False Claims Act which would reasonably be expected to result in a material Dagger Obligation. Except as described in Schedule A22.3, no Dagger Company has undergone or is undergoing any audit, review, inspection, investigation, survey or examination of records relating to any Dagger Government Contract (where such audit is either outside the ordinary course of business or would reasonably be expected to result in a material Dagger Obligation). No audit, review, inspection, investigation, survey or examination of records described in Schedule A22.3 has revealed any fact, occurrence or practice which could affect the assets, business or financial statements of any Dagger Company or any Dagger Company’s continued eligibility to receive and perform Government Contracts. To the Knowledge of Arrow, no Dagger Company has made any payment, directly or indirectly, to any Person in violation of applicable laws, including (but not limited to) laws relating to bribes, gratuities, kickbacks, lobbying expenditures, political contributions and contingent fee payments.

A22.4 Disputes, Claims and Litigation. Except as described in Schedule A22.4, to the Knowledge of Arrow, there are neither any outstanding material claims or disputes against any Dagger Company relating to any Dagger Government Contract nor any facts or allegations that could give rise to such a claim or dispute in the future. Except as described in Schedule A22.4, to the Knowledge of Arrow, there are neither any outstanding material claims or disputes relating to any Dagger Government Contract which, if resolved unfavorably to a Dagger Company, would materially increase such Dagger Company’s cost to complete performance of such Government Contract above the amounts set forth in the estimates to complete previously prepared by Arrow and delivered to Acquisition Sub for each Dagger Government Contract, nor, to the Knowledge of Arrow, any reasonably foreseeable expenditures which would materially increase the cost to complete performance of any Dagger Government Contract above the amounts set forth in the estimates to complete described above. No Dagger Company has been or is now under any administrative, civil or criminal investigation or indictment disclosed to Arrow involving alleged false statements, false claims or other misconduct relating to any Dagger Government Contract or

quotations, bids and proposals for Government Contracts, and to the Knowledge of Arrow, there is no basis for any such investigation or indictment. No Dagger Company has been or is now a party to any administrative or civil litigation involving alleged false statements, false claims or other misconduct relating to any Dagger Government Contract or quotations, bids and proposals for Government Contracts, and to the Knowledge of Arrow, there is no basis for any such proceeding. Except as described in Schedule A22.4, neither the United States Government nor any prime contractor or higher-tier subcontractor under a Government Contract has withheld or set off, or attempted to withhold (other than the hold-backs pursuant to contracts in the ordinary course of business), or set off, material amounts of money otherwise acknowledged to be due to any Dagger Company under Dagger Government Contract. Except as described in Schedule A22.4, neither the United States Government nor any prime contractor or higher-tier subcontractor under an outstanding Government Contract has questioned or disallowed any material costs claimed by any Dagger Company under any Dagger Government Contract, and to the Knowledge of Arrow, there is no fact or occurrence that could be a basis for disallowing any such costs.

A22.5 Sanctions.

No Dagger Company has received any show cause, cure, deficiency, default or similar notices relating to any Dagger Government Contract except where such violation or breach would reasonably be expected to be immaterial. No Dagger Company or any director, officer, employee, consultant or Affiliate thereof has been or is not now suspended, debarred, or proposed for suspension or debarment from government contracting, and to the Knowledge of Arrow, no facts exist which could cause or give rise to such suspension or debarment, or proposed suspension or debarment. No determination of non-responsibility has ever been issued against any Dagger Company with respect to any quotation, bid or proposal for a Government Contract.

A22.6 Terminations. Except as described in Schedule A22.6, no Government Contract of any Dagger Company relating to the Business has been terminated for default within 24 months prior to the date of this Agreement.
