2.2 Excluded Assets. Notwithstanding Section 2.1, no interest of Arrow in or to the assets listed on Schedule 2.2 (the “Excluded Assets”) is being sold, assigned or otherwise transferred to Acquisition Sub.

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 ▇▇▇▇▇▇ & ▇▇▇▇▇▇ 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.

6.2 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.

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.

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. Arrow and Crossbow agree (i) to retain all books and records with respect to Tax matters pertinent to Arrow relating to any taxable period beginning before the Closing Date until the expiration of the statute of limitations (including any extensions thereof) of the respective taxable periods, and to abide by all record retention agreements entered into with any taxing authority, and (ii) to give Acquisition Sub reasonable written notice prior to transferring, destroying or discarding any such books and records and, if Acquisition Sub so requests, allow Acquisition Sub to take possession of such books and records.

(b) Acquisition Sub and Arrow further agree, upon request, to use commercially reasonable efforts to obtain any certificate or other document from any governmental authority or any other Person as may be necessary to mitigate, reduce or eliminate any Tax that could be imposed (including, but not limited to, with respect to the transactions contemplated hereby).

(c) Acquisition Sub and Arrow further agree, upon request, to provide any other party with all information that either party may be required to report pursuant to section 6043 of the Code and all Treasury Department Regulations promulgated thereunder.

6.7.5 Certain Taxes. All transfer, documentary, sales, use, stamp, registration (and any penalties or interest relating thereto) incurred in connection with this Agreement shall be paid by Parent when due, and all other Taxes and fees (and any penalties or interest relating thereto) shall be paid by Arrow or Crossbow when due. To the extent that Arrow and Crossbow are required by law to remit sales taxes to any Governmental Entity, Parent shall pay to Arrow or Crossbow all sales taxes (and any penalties or interest relating thereto) incurred in connection with this Agreement when due, which Arrow or Crossbow, as the case may be, shall remit timely to the appropriate Government Entities. Should any Government Entity adjust the sales tax (or any penalties or interest relating thereto) incurred in connection with this Agreement by any means, including by audit or assessment, Parent shall pay to Arrow or Crossbow such adjustment when due, which Arrow or Crossbow, as the case may be, shall remit to the appropriate Government Entities. Parent will, at its own expense, prepare and file all necessary Tax Returns and other documentation with respect to all such transfer, documentary, sales, use, stamp, registration taxes, and Crossbow and Arrow will, at their own expense, prepare and file all necessary Tax Returns and other documentation with respect to all other Taxes and fees, and, if required by applicable law, each party hereto will (and will cause its Affiliates to) join in the execution of any such Tax Returns and other documentation.

6.8 Notification. From the date hereof until the Closing Date, Arrow shall promptly disclose to Parent and Acquisition Sub in writing any material changes or variances from the representations and warranties contained in Article 3 promptly upon discovery thereof, in the form of “Updated Schedules” delivered to Parent, Federal and Acquisition Sub. From the date hereof until the Closing Date, Parent, Federal and Acquisition Sub shall promptly disclose to Arrow in writing any material variances from Parent’s, Federal’s and Acquisition Sub’s representations and warranties contained in Article 4.

6.9 Accounts Receivable. Effective as of the Closing, Arrow hereby irrevocably constitutes and appoints Acquisition Sub its true and lawful attorney-in-fact, with full power of substitution, in its name, place and stead to endorse the name of Arrow on any checks and other remittances received on account of the Dagger Receivables and the Dagger Work-In-Process and to perform all other acts necessary or desirable to ▇▇▇▇ and collect the Dagger Receivables and amounts received with respect to the Dagger Work-In-Process for the account of Acquisition Sub. Arrow agrees that it shall, forthwith after receipt after the Closing, transfer and deliver to Acquisition Sub any cash or other property that Arrow may receive in respect of such Dagger Receivables or on account of the Dagger Work-In-Process, and any mail, checks or other documents received by Arrow relating to any of the Dagger Assets or Dagger Obligations transferred to Acquisition Sub hereunder, such cash, property, mail, checks and documents to be delivered in the form and condition in which received, except for the opening of any envelope or package. Arrow shall use commercially reasonable efforts to assist Acquisition Sub in the collection of the Dagger Receivables and all amounts receivable on account of the Dagger Work-In-Process after the Closing to the extent requested by Acquisition Sub to do so.

6.10 Preservation of Goodwill. To the extent required by this Agreement, Arrow shall aid Acquisition Sub in its assumption of ownership and operation of the Business and, in connection therewith, shall endeavor in good faith to maintain its goodwill and reputation (and the goodwill and reputation of the Dagger Subsidiaries) with the suppliers, clients and creditors of the Dagger Companies and any others having business relations with them and in the business community generally.

6.12.3 Notification. Each of the parties hereto will notify the other promptly upon the receipt of: (a) any comments from any officials of any Governmental Entity in connection with any filings made pursuant hereto and (b) any request by any officials of any Governmental Entity for amendments or supplements to any filings made pursuant to, or information provided to comply in all material respects with, any applicable Legal Requirement. Whenever any event occurs that is required to be set forth in an amendment or supplement to any filing made pursuant to Section 6.12.1 the Parent, the Acquisition Sub or Arrow, as the case may be, will promptly inform the other of such occurrence and cooperate in filing with the applicable Governmental Entity such amendment or supplement.

6.12.4 Best Efforts. Each of the parties agrees to use best efforts to take, or cause to be taken, all actions, and to do, or cause to be done, and to assist and cooperate with the other parties in doing, all things necessary, proper or advisable to consummate and make effective, in the most expeditious manner practicable, the Transaction and the transactions contemplated hereby, as well as the Merger and the transactions contemplated in connection therewith, including using best efforts to accomplish the following: (a) the taking of all reasonable acts necessary to cause the conditions set forth in Article 7 to be satisfied; (b) the obtaining of all necessary actions or nonactions, waivers, consents, approvals, orders and authorizations from Governmental Entities and the making of all necessary registrations, declarations and filings with Governmental Entities, if any, and the taking of all reasonable steps as may be necessary to avoid any suit, claim, action, investigation or proceeding by any Governmental Entity; (c) the obtaining of all necessary consents, approvals or waivers from third parties to the extent the failure to obtain any such consent, approval or waiver would prevent or materially hinder or delay any party’s ability to consummate the Transaction or any of the transactions contemplated hereby, or the Merger or any of the transactions contemplated in connection 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.

6.12.5 Limitation on Divestiture. Notwithstanding anything in this Agreement to the contrary, nothing contained in this Agreement shall be deemed to require the Parent or Arrow or any Subsidiary or affiliate thereof to take or agree to take any Action of Divestiture. For purposes of this Agreement, an “Action of Divestiture” shall mean making proposals, executing or carrying out agreements or submitting to Legal Requirements providing for the license, sale or other disposition or holding separate (through the establishment of a trust or otherwise) of any assets or categories of assets that are material to the Parent and its Subsidiaries or to the Business, each taken as a whole, or the holding separate of stock or assets or imposing or seeking to impose any limitation on the ability of the Parent, Arrow or any of its Subsidiaries, to conduct their respective businesses or own such assets or to acquire, hold or exercise full rights of ownership of the Business except to the extent not material to the Parent and its Subsidiaries, or the Business, each taken as a whole.

8.3 Break-up Fee. If Arrow pays a “break-up” or similar fee to Crossbow, Crossbow shall immediately remit to Parent an amount equal to one-third of such fee. Crossbow hereby covenants with Parent that should Crossbow become entitled to receive a “break-up” or similar fee from Arrow, it will use its best efforts to collect such fee from Arrow, timely and in full. Parent shall be subrogated to Crossbow to the extent of one-third of any such fee to which Crossbow becomes entitled. In addition, if Crossbow becomes entitled under the Merger Agreement to reimbursement of expenses, Crossbow shall make payment to Parent as follows: (a) if Crossbow has expenses greater than $3,333,333, Crossbow shall promptly pay Parent’s expenses up to $1,666,667; and (b) if Crossbow has expenses of less than $3,333,333, Crossbow shall promptly pay Parent’s expenses up to the amount that is the difference between $5,000,000 and Crossbow’s expenses. For the purposes of this Section 8.3, “expenses” shall mean Crossbow’s and Parent’s documented out-of-pocket expenses (including attorneys’, accountants’, financial advisors’ fees and any fees incurred by Crossbow and Parent in connection with the Transaction and the transactions contemplated by the Merger Agreement, including the filing of the Schedule TO and the Proxy/Information Statement with the Securities and Exchange Commission and the filing of (a) the Notification and Report Forms with the Federal Trade Commission and the Department of Justice under the HSR Act and the Defense Production Act and (b) the premerger notification and report forms required under the competition laws of Germany. Crossbow acknowledges that the agreements contained in this Section 8.3 are an integral part of the transactions contemplated by this Agreement, and that, without these agreements, Parent would not enter into this Agreement. Accordingly, if Crossbow fails to pay in a timely manner the amounts due pursuant to this Section 8.3, and, in order to obtain such payment, Parent makes a claim that results in a final judgment against Crossbow for the amounts set forth in this Section 8.3, Crossbow shall pay to Parent its reasonable costs and expenses (including reasonable attorneys’ fees and expenses) in connection with such suit, together with interest on the amounts set forth in this Section 8.3 at the base rate of Citibank N.A. in effect on the date such payment was required to be made plus 2%.

8.5 Entire Agreement; Amendment. Unless otherwise herein specifically provided, this Agreement and the documents and instruments and other agreements among the parties hereto as contemplated by or referred to herein (including the Ancillary Agreements) constitute the entire agreement among the parties with respect to the subject matter hereof and supersede all other prior agreements and understandings, both written and oral, between the parties with respect to the subject matter hereof, exclusive of the Confidentiality Agreements. Each party hereto acknowledges that, in entering this Agreement and completing the transactions contemplated hereby, such party is not relying on any representation, warranty, covenant or agreement not expressly stated in this Agreement or in the agreements among the parties contemplated by or referred to herein (including the Ancillary Agreements). 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. Arrow may not waive any of its rights hereunder without the written consent of Crossbow, which

consent shall not be unreasonably withheld or delayed. No party hereto shall amend the Merger Agreement without the consent of Parent, which consent shall not be unreasonably withheld or delayed.

8.6 Assignability. This Agreement is not intended to confer upon any Person other than the parties hereto any rights or remedies hereunder, except as otherwise expressly provided herein. Neither this Agreement nor any of the rights and obligations of the parties hereunder shall be assigned or delegated, whether by operation of law or otherwise, without the written consent of all parties hereto.

8.7 Validity. The invalidity or unenforceability of any provisions of this Agreement shall not affect the validity or enforceability of any other provisions of this Agreement, each of which shall remain in full force and effect.

8.8 Specific Performance. The parties hereto acknowledge that damages alone may not adequately compensate a party for violation by another party of this Agreement. Accordingly, in addition to all other remedies that may be available hereunder or under applicable law, any party shall have the right to any equitable relief that may be appropriate to remedy a breach or threatened breach by any other party hereunder, including the right to enforce specifically the terms of this Agreement by obtaining injunctive relief in respect of any violation or non-performance hereof.

8.9 Governing Law This Agreement shall be governed by, and construed and enforced in accordance with, the laws of the State of Delaware, without regard to its principles of conflicts of laws.

8.10 Counterparts. This Agreement may be executed in one or more counterparts, all of which together shall constitute one and the same agreement. Signed counterparts of this Agreement may be delivered by facsimile or other electronic transmission, and such facsimile or other electronically transmitted counterpart shall constitute an original for all purposes binding against the party who so delivers its counterpart; provided, however, that such party shall use reasonable efforts to ensure that original signed counterparts of this Agreement are delivered to all other parties by overnight courier service within 2 business days of the date of this Agreement.

8.11 Non-Survival of Representations, Warranties and Covenants. The representations and warranties of Arrow, Parent, Federal and Acquisition Sub contained in this Agreement, or any instrument delivered pursuant to this Agreement, shall terminate at the Closing, and only those covenants that by their express terms survive the Closing and this Article 8 shall survive Closing.

8.12 No Third Party Beneficiaries. This Agreement will not confer any rights upon any Person other than the parties hereto and their respective successors and assigns.

8.13 No Waiver. Unless otherwise specifically agreed in writing to the contrary; (i) the failure of any party at any time to require performance by the other of any provision of this Agreement shall not affect such party’s right thereafter to enforce the same; (ii) no waiver by any party of any default by any other shall be valid unless in writing and acknowledged by an

authorized representative of the non-defaulting party, and no such waiver shall be taken or held to be a waiver by such party of any other preceding or subsequent default; and (iii) no extension of time granted by any party for the performance of any obligation or act by any other party shall be deemed to be an extension of time for the performance of any other obligation or act hereunder.

Appendix A

A1 Corporate Status. Arrow is a corporation duly organized, validly existing and in good standing under the laws of the State of Delaware, with the requisite corporate power to own, operate and lease its properties and to carry on its business as now being conducted. 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. Schedule A1 provides a list of the states and other jurisdictions in which (i) any Dagger Subsidiary is qualified to conduct business, (ii) any Dagger Facility is located or (iii) any Dagger Employee conducts business on behalf of the Business (excluding any conduct of business or performance of services at client locations).

A2 Subsidiaries. ▇.▇. ▇▇▇▇▇▇▇▇▇▇ & Co. and Karcher Group, Inc. constitute all of Arrow’s Subsidiaries involved with the Business (each a “Dagger Subsidiary,” and, collectively, the “Dagger Subsidiaries”). Arrow owns all of the capital stock and other equity interests of the Dagger Subsidiaries, and the date on which Arrow acquired or organized each such entity is listed opposite the name of such entity on such schedule. There are no outstanding subscriptions, options, warrants, conversion rights or other rights, securities, agreements or commitments obligating any Dagger Subsidiary to issue, sell or otherwise dispose of shares of its capital stock or other equity interests, or any securities or obligations convertible into, or exercisable or exchangeable for, any shares of its capital stock or other equity interests. There are no voting trusts or other agreements or understandings to which any of Arrow or any Dagger Subsidiary (Arrow and each Dagger Subsidiary each individually a “Dagger Company,” and, collectively, the “Dagger Companies”) is a party with respect to the voting of the shares of the capital stock or other equity interests of any Dagger Subsidiary and no Dagger Subsidiary is a party to, or bound by, any outstanding restrictions, options or other obligations, agreements or commitments to sell, repurchase, redeem or acquire any of its securities. Except as set forth on Schedule A2, each Dagger Subsidiary 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.

A3 Authority for Agreement; Noncontravention

A3.1 Authority. Arrow has the corporate power and authority to enter into this Agreement and to consummate the transactions contemplated hereby to the extent of its obligations hereunder. Arrow’s execution and delivery of this Agreement and its consummation of the transactions contemplated hereby have been duly and validly authorized by its board of directors and no other corporate proceedings on its part are necessary to authorize the execution and delivery of this Agreement and the consummation of the transactions contemplated hereby. This Agreement and the other agreements contemplated hereby have been duly executed and delivered by Arrow and constitute valid and binding obligations of Arrow, enforceable against Arrow in accordance with their respective terms, subject to the qualifications that enforcement of the rights and remedies created hereby and thereby is subject to (a) bankruptcy, insolvency, reorganization, fraudulent conveyance, moratorium and other laws of general application

A-1

affecting the rights and remedies of creditors, (b) general principles of equity (regardless of whether enforcement is considered in a proceeding in equity or at law) and (c) the availability of specific performance or other equitable or legal remedies specified herein.

A3.2 No Conflict. Except as set forth on Schedule A3.2, none of the execution, delivery or performance of this Agreement and Ancillary Agreements, nor the consummation of the transactions contemplated hereby or thereby will (a) conflict with or result in a violation of any provision of the charter documents or by-laws of any Dagger Company or (b) with or without the giving of notice or the lapse of time, or both, conflict with, or result in any violation or breach of, or constitute a default under, or result in any right to accelerate or result in the creation of any Security Interest pursuant to, or right of termination under, any provision of any Dagger Material Contract or any contract listed on Schedule A16.1 (or to the Knowledge of Arrow, any other contract, note, mortgage, indenture, lease, instrument or other agreement), Permit, concession, grant, judgment, order, decree, statute, ordinance, rule or regulation to which any Dagger Company is a party (and in each case which creates or gives rise to a Dagger Obligation) or by which any of the Dagger Assets or the assets or properties of any Dagger Subsidiary are bound, or which is applicable to any Dagger Company, any Dagger Assets or any of the assets or properties of any Dagger Subsidiary. Except to the extent that novation is required as further described in Section 6.6.2 above, except for filings that may be required under the ▇▇▇▇-▇▇▇▇▇-▇▇▇▇▇▇ Antitrust Improvements Act of 1976, as amended (the “HSR Act”), the Exon-▇▇▇▇▇▇ Amendment to Section 721 of the Defense Production Act of 1950 or the competition laws of Germany, except as set forth on Schedule A3.2 and except for such consents, authorizations, filings, approvals and registrations which if not obtained or made would be immaterial, no authorization, consent or approval of, or filing with or notice to, any United States or foreign governmental or public body or authority (each a “Governmental Entity”) is necessary for the execution and delivery of this Agreement or the consummation of the transactions contemplated hereby.

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.

A-2

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.

A9.1 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.
