Lee”), Young Yong Lee (“Y. Lee”) (A. Lee and Y. Lee, each a “Stockholder” and collectively, “Stockholders”), and Jack A. Garson, as Voting Trustee (“Voting Trustee”) for the limited purpose of making the representations and warranties contained in Sections 3.2.1(b) and 3.4.1(b), amends and restates in its entirety the Asset Purchase Agreement, dated as of December 22, 2005 (“Original Agreement”), by and among Parent, Federal, Purchaser, Company, the Stockholders and the Voting Trustee.

RECITALS

R.1 The Company’s Business includes the provision of information technology, communications and logistics support primarily, although not exclusively, to the United States Government and other Governmental Entities.

R.2 A. Lee and Y. Lee, respectively, own 90 shares (or 9%) and 910 shares (or 91%) of the Company’s outstanding common stock, no par value (the “Common Stock”). To the extent provided in the Voting Trust Agreement, the Voting Trustee owns of record the above-referenced 910 Shares beneficially owned by Y. Lee.

R.3 Purchaser desires to purchase substantially all of the assets and assume certain liabilities related to the Business and the Company desires to sell such assets and assign such liabilities to Purchaser.

R.4 The respective boards of directors of the Company, Parent, Federal and Purchaser have determined that it is advisable that (a) the Company sell and assign and that Purchaser purchase and assume the above-referenced assets and liabilities, respectively, and (b), in connection therewith, to consummate certain other transactions (collectively with such sale and purchase of the assets and assignment and assumption of liabilities, the “Transactions”), all on the terms and conditions set forth herein.

R.5 The Parties desire to make certain representations, warranties, covenants and other agreements in connection with the Transactions.

NOW, THEREFORE, in consideration of the mutual promises hereinafter set forth and other good and valuable consideration, the receipt and adequacy of which are hereby acknowledged, the Parties, intending to be legally bound, agree as follows:

Article 1

Certain Matters of Construction and Definitions

1.1 Construction and Definitions. Certain matters of construction of this Agreement and the definition of capitalized terms used herein but not otherwise defined in Articles 1 through 9 are set forth in Schedule 1.

9

Article 2

The Purchase and Sale of Assets

2.1 Purchase and Sale of Assets. Upon and subject to the terms and conditions set forth in this Agreement, at the closing of the Transactions (the “Closing”), (a) the Company shall sell, transfer, convey or assign and deliver to Purchaser, and Purchaser shall purchase and acquire from the Company, all right, title and interest in, under and to the Purchased Assets, in each case, free and clear of any and all Encumbrances, except Permitted Encumbrances and to the extent novations are required as described in Section 6.6.2 (“Novations”); and (b) Purchaser shall agree to assume and perform when and as they become due after the Closing the Assumed Liabilities. Notwithstanding the foregoing, no interest of the Company in or to the Excluded Assets is being sold, transferred, conveyed or assigned to Purchaser under this Agreement.

2.2 Purchase Price. On the terms and conditions set forth in this Agreement, as full consideration for the Purchased Assets, Purchaser shall pay the sum of $145,000,000, as adjusted and as otherwise provided herein (the “Purchase Price”):

2.2.1 Payment of Purchase Price.

(a) The Purchase Price sum of $145,000,000, less (i) the $7,250,000 to be delivered to the Escrow Agent pursuant to Section 2.2.1(b) (the “Escrow Payment”) and (ii) the amounts paid pursuant to Section 6.2.2, shall be paid at Closing to the Company.

(b) For the purpose of securing the Company’s and Stockholders’ obligations pursuant to Section 6.3, the Escrow Payment shall be delivered at Closing to the Escrow Agent by wire transfer to an account to be designated and administered by the Escrow Agent pursuant to the Escrow Agreement (the “Escrow”).

(c) Purchase Price payments made pursuant to Section 2.2.1(a) will be paid in immediately available funds by wire transfer to one or more of the accounts designated by the Company Representative.

2.2.2 Post-Closing Adjustments to Purchase Price.

2.2.2.1 Preparation of Closing Balance Sheet. As soon as reasonably possible after the Closing Date (but not later than 120 days thereafter), the Company shall prepare or cause to be prepared and shall deliver to Purchaser the unaudited balance sheet of the Purchased Assets and Assumed Liabilities as of immediately before the Effective Time (the “Closing Balance Sheet”). The Closing Balance Sheet shall be prepared in accordance with GAAP applied in a manner consistent with the Audited Balance Sheet.

2.2.2.2 Review of Closing Balance Sheet. Purchaser, upon receipt of the Closing Balance Sheet, shall (a) review the Closing Balance Sheet and (b) to the extent it may deem necessary, make reasonable inquiry of the Company and its

10

accountants (if any are used), related to the preparation of the Closing Balance Sheet. Purchaser and its advisors shall have full access upon prior notice and during normal business hours to the books, papers and records of the Business and its accountants (if any are used), relating to the preparation of the Closing Balance Sheet in connection with such inquiry. The Closing Balance Sheet shall be final, binding and conclusive upon, and deemed accepted by, the Parties unless Purchaser shall have notified the Company Representative of any Purchaser objections thereto within 30 days after receipt of the Closing Balance Sheet (“Purchaser Objection”).

2.2.2.3 Disputes. If a Purchaser Objection occurs, the Company Representative shall have 20 days to review and respond to the Purchaser Objection, and Purchaser and the Company Representative shall attempt to resolve the differences underlying the Purchaser Objection within 20 days following completion of the Company Representative’s review of the Purchaser Objection. Disputes between Purchaser and the Company Representative which are not resolved by them within such 20-day period shall be referred no later than such 20 day for decision to an independent accounting firm of national reputation mutually acceptable to Purchaser and Company Representative (which firm shall not be (a) any independent public accountant which has a business relationship with Parent or Parent’s Affiliates or (b) the independent public accountant of Company) (the “Auditor”), which shall act as arbitrator of such dispute in accordance with this Section 2.2.2.3. If Purchaser and the Company Representative cannot agree upon the selection of the Auditor within five Business Days, Grant Thornton LLP shall serve as the Auditor hereunder. Purchaser and Company Representative each agree to execute a reasonable engagement letter proposed by the Auditor. The Auditor shall prescribe procedures for resolving the disputed items and in all events shall make a written determination, with respect to the disputed items only, whether and to what extent, if any, the items in dispute on the Closing Balance Sheet need adjustment (the “Determination”). The Determination shall be based solely on presentations of such disputed items by Company Representative and Purchaser to the Auditor and not the Auditor’s independent review; provided that such presentations shall be deemed to include any work papers, records, accountants or similar materials delivered to the Auditor in connection with such presentations and any materials delivered in response to Auditor’s requests. Each of Purchaser and Company Representative shall use its reasonable best efforts to make its presentations as promptly as practicable following submission to the Auditor of the disputed items, and each party shall be entitled, as part of its presentation, to respond to the presentation of the other party and any questions or requests of the Auditor. Purchaser and Company Representative shall instruct the Auditor to deliver the Determination to Purchaser and Company Representative within 60 days after the date on which the disputed items are referred to the Auditor. In deciding any matter hereunder, the Auditor (a) may not assign a value to any disputed item greater than the greatest value for such item claimed by Purchaser or Company Representative or less than the smallest value for such disputed item claimed by Purchaser or Company Representative, and (b) shall be bound by the terms and conditions set forth in this Agreement, including this Section 2.2.2.3 and the definition of Net Assets contained herein. In the absence of fraud or manifest error, the Determination shall be final, conclusive and binding upon the Parties. The fees and disbursements of the Auditor shall be allocated equally between Purchaser on one hand and the Company on the other hand. Purchaser and the Company Representative shall make readily available to the Auditor all relevant information, books and records and any work papers, schedules and calculations relating to the Closing Balance Sheet and all other items reasonably requested by the Auditor, and the Auditor shall be required to maintain the confidentiality of the information and documents received by the Auditor hereunder.

11

2.2.2.4 Final Closing Balance Sheet. The Closing Balance Sheet shall become final, conclusive and binding upon the Parties upon the earliest of (a) Purchaser’s failure to provide a Purchaser Objection within the period permitted under Section 2.2.2.2, (b) the agreement between Purchaser and the Company Representative with respect thereto, and (c) the decision by the Auditor with respect to any disputes under Section 2.2.2.3. The Closing Balance Sheet (a) as submitted to Purchaser with its failure to provide a Purchaser Objection within the period permitted under Section 2.2.2.3, (b) as adjusted pursuant to the agreement of Purchaser and Company Representative or (c) the decision of the Auditor, shall constitute the final, conclusive and binding Closing Balance Sheet referred to herein as the “Final Closing Balance Sheet.”

2.2.2.5 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 2.2.2, (a) the Company and Company Representative shall pay to Purchaser, in immediately available funds, the amount, if any, by which the Net Assets as reflected on the Final Closing Balance Sheet are less than $25,000,000, which shall constitute an immediate decrease of the Purchase Price in such amount, (b) as the case may be, Purchaser shall pay to the Company Representative, in immediately available funds, the amount, if any, by which the Net Assets as reflected on the Final Closing Balance Sheet are greater than $25,000,000, which shall constitute an immediate increase of the Purchase Price in such amount.

2.3 The Closing and Instruments of Transfer and Assumption.

2.3.1 The Closing. Subject to the satisfaction (or waiver) of all of the conditions precedent to the obligations of the Parties to consummate the Closing set forth in Article 7 (the “Closing Conditions”), the Closing shall take place at the Parent’s offices located at 1100 North Glebe Road, Arlington, Virginia, 22201, commencing at 9 a.m. local time (a) on January 31, 2006, or (b) if the Closing Conditions have not been satisfied in full (or waived) by such date, on such other date that is the first Business Day after the date on which all of the Closing Conditions (other than such conditions to be satisfied on the Closing Date) are satisfied (or waived) or (c) on such other date as the Parties may agree after the satisfaction (or waiver) of all the Closing Conditions (the date of Closing, being the “Closing Date”). Notwithstanding anything herein to the contrary, if the Closing occurs, all of the Transactions shall be deemed to have occurred concurrently and retroactively, for all purposes, as of 12:01 a.m. on the first day after the Closing Date (the “Effective Time”).

2.3.2 Instruments of Transfer and Assumption. The Company shall effect the transfer of the Purchased Assets to Purchaser at the Closing by such bills of sale, assignments and other instruments of transfer as Purchaser or its counsel and the Company or its counsel mutually deem reasonably necessary or appropriate to transfer to Purchaser full legal and beneficial title to the Purchased Assets free and clear of all Encumbrances except the Permitted Encumbrances, Assumed Liabilities and Novations. All of such transfer documents shall contain appropriate and customary warranties and covenants of title and shall be in form and substance reasonably acceptable to Purchaser and its counsel and the Company and its counsel. The Company shall also effect the transfer of the Assumed Liabilities to and assumption by Purchaser at the Closing by such assignments, assumptions and other instruments of assignment, assumption and transfer as Purchaser or its counsel and the Company or its counsel mutually deem reasonably necessary or appropriate to transfer full legal to and beneficial obligation of the Assumed Liabilities.

6.3.1 Indemnification of Parent Indemnified Parties. Subject to this Section 6.3, from and after the Closing Date, Parent, Federal, Purchaser, each Affiliate of Parent and their respective directors, officers, employees, Affiliates, representatives, successor and assigns (collectively “Parent Indemnified Parties”) shall be entitled to

38

payment and reimbursement from the Company and Stockholders, jointly and severally (collectively the “Parent Indemnifying Parties”) of the amount of Losses suffered, incurred or paid by any Parent Indemnified Party, by reason of or otherwise arising from (a) any breach by the Company, any Stockholder or Voting Trustee of any covenant, agreement or obligation in this Agreement (whether to be performed before, on or after the Closing Date), (b) in respect of any Excluded Liabilities, (c) any misrepresentation or inaccuracy in, or breach of, any representation or warranty made by the Company, any Stockholder or Voting Trustee in Article 3 or any Exhibits or the certificates or other Closing documents delivered pursuant Section 7.2, or (d) any one or more Covered Matters. Notwithstanding anything herein to the contrary, if there is a misrepresentation or inaccuracy in, or a breach of, a representation or warrant in Article 3 or in a certificate given pursuant to Section 7.2.1 which has a Materiality Qualification (which breach shall be determined giving effect to such Materiality Qualification), the Parent Indemnified Parties shall be entitled to indemnification for all Losses suffered, incurred or paid by any Parent Indemnified Party by reason of or otherwise arising from such aforesaid misrepresentation, inaccuracy or breach, with such indemnifiable Losses determined as if the Materiality Qualification were deleted from the one or more respective misrepresented, inaccurate or breached representations and warranties subject to Section 6.3.5.2 and all other applicable terms and conditions of Section 6.3.

6.3.2 Indemnification of Company Indemnified Parties. Subject to this Section 6.3, from and after the Closing Date, the Company and each Stockholder (collectively “Company Indemnified Parties”) shall be entitled to payment and reimbursement from Parent, Federal and Purchaser, and their respective successors and assigns (collectively the “Parent Indemnifying Parties”) of the amount of Losses suffered, incurred or paid by any Company Indemnified Party by reason of or otherwise arising from, (a) any breach by Parent, Federal or Purchaser of any covenant, agreement or obligation in this Agreement to be performed before, on or after the Closing Date, (b) in respect of any Assumed Liabilities, and (c) any misrepresentation or inaccuracy in, or breach of any, representation or warranty contained in Article 4 or in the certificates delivered pursuant to Section 7.3.

6.3.3 Claims for Indemnification. Upon a Person entitled to indemnification under Section 6.3 (“Indemnified Party”) obtaining reasonably sufficient knowledge of any facts, claim or demand which has given rise to, or would reasonably give rise to, a claim for indemnification hereunder (referred to herein as an “Indemnification Claim”), such Indemnified Party shall promptly thereafter give notice of such facts, claim or demand (“Notice of Claim”) to the Party from whom indemnification is sought hereunder (the “Indemnifying Party”). So long as the Notice of Claim is given by the Indemnified Party within the respective claim period specified in Section 6.3.6, no failure or delay by the Indemnified Party in the giving of a Notice of Claim shall reduce or otherwise affect the Indemnified Party’s right to indemnification except to the extent, if any, that the Indemnifying Party has been materially prejudiced thereby.

6.3.4 Defense by Indemnifying Party. If a claim or demand is asserted by a third party against an Indemnified Person which involves or appears reasonably likely to involve an Indemnification Claim (a “Third Party Claim”), the Indemnifying Party shall have the right, but not the obligation, exercisable by notice to the Indemnified Party within 10 days of the date of the Notice of Claim concerning the commencement or assertion of a Third Party Claim, to assume the defense of such Third Party Claim provided, however, that the Parent Indemnifying Parties shall not have such right or

39

opportunity to assume and control the defense of any such Third Party Claim, but shall have the right to participate in the defense of such Third Party Claim and shall pay the reasonable fees and expenses of counsel retained by the Parent Indemnified Party in respect of the Third Party Claim if (a) such Third Party Claim relates to, or arises in connection with, any criminal proceeding, civil action, indictment, or investigation by any Governmental Entity other than inquiries or audits in the ordinary course of business, (b) such Third Party Claim alleges Losses in excess of the then available funds held in Escrow (after deducting the full amount of all pending Indemnification Claims), (c) the Parent Indemnified Party reasonably believes that an adverse determination with respect to such Third Party Claim would be detrimental to the Parent Indemnified Party’s reputation or continuing business interests, (d) such Third Party Claim seeks an injunction or other equitable relief against the Parent Indemnified Party, or (e) the Parent Indemnifying Parties fail to conduct the defense of such Third Party Claim actively and diligently. The applicable Parent Indemnified Party agrees to defend any such Third Party Claim consistent with the best interest of such Parent Indemnified Party, subject to Section 6.3.13. If the Parent Indemnified Party assumes and controls the defense of a Third Party Claim pursuant to this Section 6.3.4, the Parent Indemnified Party shall permit the Parent Indemnifying Parties to participate in the defense of such claim, have reasonable access to all documents and personnel involved in such claim and to discuss its views and positions with the Parent Indemnified Party. The Parent Indemnified Party agrees, in connection with any such Third Party Claim to work cooperatively and in good faith with the Parent Indemnifying Parties consistent with the best interest of the Parent Indemnified Party. If the Indemnifying Party is entitled under this Section 6.3.4 to assume the defense of the respective Third Party Claim and gives such notice of intent to defend, the Indemnifying Party shall assume the defense thereof as follows: (a) the Indemnifying Party will defend the Indemnified Party against the matter with counsel compensated by and chosen by Indemnifying Party, which choice of counsel is subject to the reasonable satisfaction of Indemnified Party; (b) the Indemnified Party may retain separate co-counsel at the sole cost and expense of Indemnified Party; (c) the Indemnified Party will not consent to the entry of any judgment or enter into any settlement with respect to the matter without the consent of the Indemnifying Party; and (d) the Indemnifying Party will not consent to the entry of any judgment with respect to the matter, or enter into any settlement that does not include a provision whereby the plaintiff or claimant in the matter releases the Indemnified Party from all Liability with respect thereto, without the consent of the Indemnified Party, which consent shall not be unreasonably withheld or delayed if such settlement only requires the payment by one or more Indemnifying Parties of a monetary amount, does not include a statement as to admission of fault, culpability or failure to act by or on behalf of such Parent Indemnified Party, and Parent Indemnified Party could not reasonably believe that the settlement would be detrimental to the Parent Indemnified Party’s reputation or continuing business. If a Third Party Claim is made and no Indemnifying Party notifies the Indemnified Party within 10 days after the Indemnified Party has given notice of the matter that the Indemnifying Party is assuming the defense thereof, the Indemnified Party shall defend against, or enter into any settlement with respect to the matter. The Indemnified Party shall not settle such Third Party Claim without the prior consent of the Indemnifying Party, which consent shall not be unreasonably withheld or delayed.

6.3.5 Limitation on Liability for Indemnity.

6.3.5.1 Parent Indemnity Deductible. Except for Company Asset Ownership Claims and Indemnification Claims based on fraud (collectively, “Excepted

6.3.5.2 Certain Caps on Indemnification Liability. Except for Excepted Claims, (a) the aggregate Liability of the Company and Stockholders under this Section 6.3 in respect of (i) a breach of any Pre-Closing Covenant and (ii) a misrepresentation or inaccuracy in, or breach of, any representation or warranty in Article 3 (including any updated Article 3 Schedules) (clauses (a) and (b) collectively, the “Capped Claims”) shall not exceed (1) the Escrow Payment, plus any interest and other income earned thereon, and (2) the amount, if any, paid from the Escrow for any one or more Excepted Claims, and (b) Parent Indemnified Parties shall only be entitled under this Section 6.3 for indemnification of their Losses attributable to Capped Claims from the Escrow, except, if any, amounts are paid from the Escrow for Excepted Claims, the Company and Stockholders shall be jointly and severally liable for Losses attributable to Capped Claims in an aggregate amount not to exceed such Losses attributable to Excepted Claims paid from the Escrow. Notwithstanding anything herein to the contrary, the total Liabilities of the Parent Indemnifying Parties under this Agreement shall not exceed the Purchase Price, as adjusted pursuant to Section 2.2.

If a Parent Indemnified Party incurs a Loss that would also be subject to an Indemnification Claim under either of clause (c) and clause (b) of the first sentence of Section 6.3.1, such Parent Indemnified Party’s sole and exclusive remedy for such Loss shall be an Indemnification Claim pursuant to the above-referenced clause (c); provided, however, that if such Loss would not recoverable under such clause (c) solely because of a Materiality Qualification in the respective representation or warranty, the Parent Indemnified Party shall not be entitled to indemnification for such Loss except pursuant to a breach of Section 3.27; and provided further that nothing herein is intended to waive any claims for fraud or any equitable remedies to which a Party may be entitled.

6.4 Access and Information. The Company shall afford to Parent and a reasonable number of its officers, employees, accountants, counsel and other authorized representatives full and complete access, upon reasonable advance telephone notice and during regular business hours, throughout the Pre-Closing Period, to the Company’s offices, properties, books and records, and shall use reasonable efforts to cause its representatives and independent public accountants to furnish to Parent such additional financial and operating data and other information as to its business, customers, vendors and properties as Parent may from time to time reasonably request.
