(a) The Company shall have delivered to the Buyer a balance sheet of the Company, updated from and after the Balance Sheet Date (the “Estimated Closing Balance Sheet”), which the Company shall certify as being a good faith estimate of the balance sheet of the Company as of the Closing Date.

(b) In the event that the Company Stockholder Equity as set forth in the Estimated Closing Balance Sheet is less than or greater than the Company Stockholder Equity Amount, the Buyer shall adjust the Closing Payment to be delivered to the Company Stockholders at Closing (a “Closing Payment Adjustment”) as follows:

(c) Within sixty (60) days after the Closing Date, the Buyer and the Stockholder Representative shall agree to a statement of work (the “Statement of Work”) pursuant to which an audit firm will audit on a timely basis the Company’s financial statements, books and records and prepare and deliver to the Buyer and Stockholder Representative a Selected Accountant’s Certificate (as defined below). Such audit will be conducted in conformance with the provisions of Section 2.7 and the Selected Accountants’ Certificate shall be prepared in conformance with the provisions of Section 2.7. The Buyer shall deliver the Statement of Work to each audit firm listed on Schedule 2.4(c) hereto and request a proposal from each. The Buyer and the Stockholder Representative shall select from among the proposals the lowest bidding firm which has indicated that it can accomplish the requirements of the Statement of Work in the time frame indicated therein (the “Selected Accountants”). The Company Accountants shall provide a signed certificate (the “Selected Accountants’ Certificate”) certifying the Selected Accountants’ determination of the Company Stockholder Equity as of the Closing Date, and identifying any adjustments to the Company Stockholder

Equity as reflected on the Estimated Closing Balance Sheet, which determination will become final and binding upon the Parties unless, within thirty (30) days following delivery of the Selected Accountants’ Certificate, the Buyer or the Stockholder Representative objects in the manner set forth below. If the Final Company Stockholder Equity (as defined below) is greater than the Company Stockholder Equity as reflected on the Estimated Closing Balance Sheet, the Buyer shall, within three (3) business days, pay to the Company Stockholders, the amount of such difference in their respective Percentage Interests. If the Final Company Stockholder Equity is less than the Company Stockholder Equity as reflected on the Estimated Closing Balance Sheet, the amount of such difference shall, within three (3) business days, be paid to the Buyer from the Escrow Fund. As used herein, the term “Final Company Stockholder Equity” shall mean the Company Stockholder Equity reflected in the Selected Accountants’ Certificate if uncontested, or the amount finally determined by negotiation of the Parties or by the Neutral Auditor, as provided below.

(d) The cost of retaining the Company Accountants to conduct such review and to prepare such certificate shall be borne by equally by the Company Stockholders and the Buyer. The Buyer shall permit the Stockholder Representative and, if applicable, the Neutral Auditor (as defined below) access to such work papers and all other applicable documents of the Company relating to the preparation of the Selected Accountants’ Certificate as may be reasonably necessary to permit the Buyer, the Neutral Auditor and the Stockholder Representative to review in detail the manner in which the Selected Accountants’ Certificate was prepared. If the Buyer or the Stockholder Representative objects to any item on the Selected Accountants’ Certificate, the Buyer or the Stockholder Representative shall notify the Company Accountants in writing of such objection within thirty (30) days after the Buyer’s and Stockholder Representative’s receipt of the Selected Accountants’ Certificate (such notice setting forth in reasonable detail the basis for such objection). The Buyer and the Stockholder Representative shall thereafter negotiate in good faith to resolve any such objections. If the Buyer and the Stockholder Representative are unable to resolve any such disagreements within fifteen (15) days of the Buyer’s (or the Stockholder Representative’s) receipt of the Stockholder Representative’s (or the Buyer’s) objections, the Buyer and the Stockholder Representative shall jointly retain Ernst & Young LLP or another mutually agreed to national accounting firm (the “Neutral Auditor”) to resolve any remaining disagreements. At the time of the Neutral Auditor’s selection, each of the Buyer and the Company Stockholders shall represent and warrant that, at such time, it does not have and has not had any material relationship with the Neutral Auditor in any capacity, including without limitation, as an auditor, consultant or teaming partner. Each Party agrees to execute, if requested by the Neutral Auditor, a reasonable engagement letter with the Neutral Auditor. The Neutral Auditor shall determine only those issues in dispute at the end of the resolution period and the Neutral Auditor’s determination shall be based upon and consistent with the terms and conditions of this Agreement. The determination by the Neutral Auditor shall be based solely on presentations with respect to such disputed items by the Buyer and the Stockholder Representative to the Neutral Auditor and not on the Neutral Auditor’s independent review. Each of the Buyer and the Stockholder Representative shall use its reasonable best efforts to make its presentation as promptly as practicable following submission to the Neutral Auditor of the disputed items, and each such Party shall be entitled, as part of its

presentation, to respond to the presentation of the other Party and any questions and requests of the Neutral Auditor. In deciding any matter, the Neutral Auditor (i) shall be bound by the provisions of this Section 2.4(d) and (ii) may not assign a value to any item greater than the greatest value for such item claimed by either the Buyer or the Stockholder Representative or less than the smallest value for such item claimed by the Buyer or the Stockholder Representative. The Buyer and the Stockholder Representative shall direct the Neutral Auditor to render a determination within forty-five (45) days of its retention (which retention shall be made no later than five (5) business days after the 15-day period), or as soon thereafter as possible, and the Buyer and the Stockholder Representative shall use commercially reasonable efforts to cause the Neutral Auditor to resolve all disagreements over individual line items as soon as possible. The Neutral Auditor shall consider only those items and amounts in the Selected Accountants’ Certificate which the Buyer and the Stockholder Representative are unable to resolve. The determination of the Neutral Auditor shall be final, conclusive, non-appealable and binding upon the Buyer and the Company Stockholders for all purposes hereunder, provided that such determination may be reviewed, corrected or set aside by a court of competent jurisdiction but only upon a finding that the Neutral Auditor committed manifest error with respect to its determination. All fees and expenses (including reasonable attorneys’ fees and expenses and fees and expenses of the Neutral Auditor) incurred in connection with any dispute over the Selected Accountants’ Certificate shall be borne by the Parties based on the percentage which the portion of the contested amount not awarded to each Party bears to the amount actually contested by such Party. Any amounts required to be paid by or on behalf of the Company Stockholders shall be based upon their respective Percentage Interests.

2.5 No Further Rights. The Purchase Price paid for the Company Stock in accordance with the terms hereof shall be deemed to have been paid in full satisfaction of all rights pertaining to such Company Stock.

2.6 Taking of Necessary Action; Further Action. If, at any time after the Closing, any further action is necessary or desirable to carry out the purposes of this Agreement and to vest the Buyer with full right, title and possession to all assets, property, rights, privileges, powers and franchises of the Company, the Company Stockholders agree to take, and will take, all such lawful and necessary action required to so do, so long as such action is not inconsistent with this Agreement.

2.7 Accounting Terms. Except as otherwise expressly provided herein or in the Schedules hereto, all accounting terms used in this Agreement shall be interpreted, and all financial statements, Schedules, certificates and reports as to financial matters required to be delivered hereunder shall be prepared, in accordance with generally accepted accounting principles (“GAAP”), consistently applied by Company; provided, however, that in the event that any accounting principles consistently applied by Company are not in accordance with GAAP, then the Selected Accountants shall use accounting principles that conform with GAAP and which are customarily applied by firms in the government information technology services industry. Notwithstanding the foregoing, the Interim Financials shall not be required to contain (a) notes otherwise required under GAAP or (b) any normal year-end adjustments. Furthermore,

subject to the above provisions, the parties understand and acknowledge that there are elements to GAAP that are subject to interpretation and that there may be more than one acceptable method of handling a particular item under GAAP.

2.8 Form of Payments. All payments made pursuant to this Agreement shall be made by delivery to the recipient by bank wire transfer, the required amount (in immediately available funds) in an account of the recipient, which account shall be designated by the recipient in writing at least three (3) business days prior to the date of the required payment; provided, that in the case of each payment to be made to Company Stockholders hereunder, such payments shall be made to each of the Company Stockholders in accordance with his or her Percentage Interest.

5.5 Unpaid Taxes; Refunds. The Company Stockholders, jointly and severally, covenant and agree to reimburse promptly the Buyer for any amount by which the Company’s liability for unpaid Taxes, if any, for all periods or portions thereof ending on or before the Closing Date exceeds the amount of the current liability accruals for Taxes (excluding reserves for deferred Taxes) set forth on the Company Financial Statements as such accruals are adjusted on the books and records of the Company for operations and transactions in the Ordinary Course of Business through the Closing Date in accordance with past custom and practice of the Company; provided that if any such unpaid Taxes result from an amended Tax Return or the audit of a Tax Return, the procedures set forth in Sections 5.6(b) and (c) below shall have been fully complied with by the Buyer.

5.6 Tax Returns.

(a) The Company shall prepare and timely file, and the Stockholder Representative and the Buyer shall cooperate with the Company in the preparation and timely filing of, all Tax Returns required to be filed by or on behalf of the Company prior to the Closing Date. The Buyer and the Stockholder Representative shall have a reasonable opportunity to review and consent to the filing of such Tax Returns, which consent shall not be unreasonably withheld or delayed. The Company shall timely pay any Taxes shown as due by the Company on the Tax Returns described in this Section 5.6.

(b) If any Tax shown as due on any such Tax Return referred to in (a) above is required to be borne by the Company Stockholders (taking into account indemnification obligations hereunder and adjustments to the Purchase Price) or affects taxable income reportable by the Company Stockholders by reason of their former ownership of their Company Stock, such Tax Return shall be prepared in a manner consistent with the prior practice of the Company unless otherwise required by applicable Tax laws; a draft of each such Tax Return shall be provided to the Stockholder Representative for review and approval at least thirty (30) days prior to the due date for filing such return (or, if required to be filed within thirty (30) days of the Closing, as soon as possible following the Closing); and the Stockholder Representative shall have the right to review and approve such Tax Return prior to the filing of such Tax Return (which approval shall not be unreasonably withheld or delayed).

(c) The Parties shall, unless prohibited by applicable law, cause the taxable period of the Company to end as of the close of the Closing Date. For the avoidance of doubt, the Parties hereto agree that the taxable year of the Company, as a subchapter S corporation, shall

For purposes of this Agreement, Taxes incurred by the Company with respect to a taxable period that includes but does not end on the Closing Date, shall be allocated to the portion of the taxable period ending on the Closing Date (the “Pre-Closing Period”) (i) except as provided in (ii) and (iii) below, to the extent feasible, on a specific identification basis, according to the date of the event or transaction giving rise to the Tax, and (ii) except as provided in (iii) below, with respect to periodically assessed ad valorem Taxes and Taxes not otherwise reasonably allocable to specific identifiable transactions or events or dates, in proportion to the number of days in such taxable period that occur on or before the Closing Date compared to the total number of days in such taxable period, and (iii) in the case of any Tax based upon or related to income or receipts, in an amount equal to the Tax which would be payable if the relevant taxable period ended on the Closing Date. All determinations necessary to give effect to the foregoing allocations shall be made in a manner consistent with prior practice of the Company.

5.7 Cooperation on Tax Matters.

(a) The Buyer, the Company and the Stockholder Representative (at no expense to the Stockholder Representative) shall cooperate fully, as and to the extent reasonably requested by the other Parties, in connection with the filing of Tax Returns pursuant to this Section and any audit, litigation or other proceeding with respect to Taxes. Such cooperation shall include the retention and (upon the other Parties’ request) the provision of records and information that are reasonably relevant to any such audit, litigation or other proceeding and making employees available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder. The Stockholder Representative agrees (i) to retain all books and records with respect to Tax matters pertinent to the Company relating to any taxable period beginning before the Closing Date until the expiration of the statute of limitations (and, to the extent notified by the Buyer or the Stockholder Representative, 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 the other Parties reasonable written notice prior to transferring, destroying or discarding any such books and records and, if the other Parties so request, the Company or the Stockholder Representative, as the case may be, shall allow the other Parties to take possession of such books and records.

(b) Except in connection with an audit resolved pursuant to Section 5.7(c) (including consistent correlative adjustments to Tax Returns for non-audited taxable periods), no Party may amend a Tax Return filed by any Party with respect to the Company or file or amend any Tax election of the Company, in each case, for a taxable period beginning prior to the Closing Date, without the consent of the other Parties hereto, not to be unreasonably withheld or delayed. The Buyer shall, upon request by Stockholder Representative and at the sole expense of the Company Stockholders, cooperate in the preparation of and submission to the proper taxing

authority of any such amended Tax Return which is required to cause such Tax Return to be consistent with adjustments to the Tax Returns of the Company for any other taxable period proposed by any taxing authority, or to give effect to an allowable loss carryback or carryover from a taxable period of the Company ending on or before the Closing Date.

(c) Any Party who receives any notice of a pending or threatened Tax audit, assessment, or adjustment relating to the Company, or the Company Stockholders with respect to the Company, which may give rise to liability of another Party hereto, shall promptly notify the Buyer and the Company Stockholders within ten (10) business days of the receipt of such notice. The Parties each agree to consult with and to keep the other Parties hereto informed on a regular basis regarding the status of any Tax audit or proceeding to the extent that such audit or proceeding could affect a liability of such other Parties (including indemnity obligations hereunder). The Stockholder Representative shall have the right to represent the Company’s interests in any Tax audit or administrative or judicial proceeding and to employ counsel of the Stockholder Representative’s choice, but reasonably satisfactory to the Buyer, at their expense, but only to the extent such audit or other proceeding pertains to taxable periods ending on or before the Closing Date. The Buyer shall have the right to participate in such proceeding at its own expense, and shall be entitled to control the disposition of any issue involved in such proceeding which does not affect a potential liability of the Company Stockholders. The Buyer and the Company Stockholders (through the Stockholder Representative) shall be entitled to represent their own interests in light of their responsibilities (including indemnity obligations) for the related Taxes, at their own expense, in any audit or administrative or judicial proceedings involving a taxable period that includes but does not end on the Closing Date. Notwithstanding the foregoing, the Stockholder Representative shall not agree to any settlement for any taxable period that would effect Tax liabilities of the Buyer or the Company for any taxable period beginning on or after the Closing Date without prior written consent of the Buyer.

(d) The Buyer and the Company Stockholders shall jointly make a timely election provided for by Section 338(h)(10) of the Code and Section 1.338(h)(10) of the Treasury regulations (and any comparable election under state or local laws) (collectively, the “Election”) with respect to the acquisition of the Company Stock. The Purchase Price shall be allocated among the assets of the Company for purposes of completing all forms of any nature necessary to effectuate the Election (including, but not limited to, Internal Revenue Service Form 8023, Corporate Qualified Stock Purchase, Form 8883 (Asset Allocation Statement) and any similar forms under applicable state or local law) (the “Section 338 Forms”) in accordance with applicable U.S. Treasury regulations. Such allocation shall be agreed upon by the Buyer and the Stockholder Representative as of the Closing Date and shall be set forth on Exhibit D attached hereto and made a part hereof. Based on such allocation, the Buyer and the Stockholder Representative shall jointly prepare the Section 338 Forms and the Buyer and the Company shall execute and deliver the Section 338 Forms to one another for filing. The Company and the Buyer shall duly and timely file the Section 338 Forms in accordance with applicable tax laws and in accordance with this Agreement. The Company and the Buyer shall report the acquisition by the Buyer of the Company Stock pursuant to this Agreement consistent with the Elections and shall take no position contrary thereto or inconsistent therewith in any Tax Return, any

discussion with or proceeding before any taxing authority, or otherwise. The Buyer agrees to provide the Stockholder Representative within thirty (30) days of the Closing Date written instructions in accordance with applicable law as to what is necessary to file a timely, valid Election. The Company Stockholders and the Company Representative agree to comply with such reasonable instructions.

In the event the parties are unable to agree as to the allocations referred to above, the parties shall appoint an independent accountant to resolve such dispute whose costs shall be borne equally by such parties.

(e) The Buyer and the Company Stockholders further agree, upon request, to use their reasonable efforts (without expense to the Company Stockholders) to obtain any certificate or other document from any Governmental Entity or any other Person as may be necessary to mitigate, reduce or eliminate any Tax that could be imposed (including, without limitation, with respect to the transactions contemplated hereby).

(f) The Buyer shall pay the Company Stockholders as additional consideration an amount equal to fifty percent (50%) of the additional state and federal taxes incurred directly by the Company Stockholders solely from the Election, up to an aggregate payment amount of Five Hundred Thousand Dollars ($500,000) (the “Tax Amount”). Such amount shall be calculated by the Stockholder Representative and submitted to the Buyer for its approval along with supporting work papers. Such approval shall not be unreasonably withheld. The Tax Amount shall be allocated pro rata among the Company Stockholders in accordance with their ownership interest of the Company Stock. If the Parties are unable to agree as to the Tax Amount, such dispute shall be resolved by an independent accountant chosen by the Parties whose costs shall be borne equally by the Parties.

(g) The Buyer covenants that it will not and will not cause or permit the Company or any Affiliate of the Buyer to (i) take any action on the Closing Date other than in the Ordinary Course of Business, including, without limitation, the distribution of any dividend or the effectuation of any redemption which would result in any tax liability to the Company Stockholders, or (ii) make any election or deemed election under Section 338 of the Code on the Closing Date other then the Election or amend any Tax Return of the Company on the Closing Date.

or regulation) in full force. Subject to the foregoing, the Buyer may, from and after the Closing, cause the Company to merge, dissolve or reorganize.

(b) For a period of four (4) years after the Closing, the Buyer shall maintain or cause the Company to maintain directors and officers liability insurance with coverage in respect of periods prior to the Closing in amount and scope substantially identical to that provided to the Company under its policy no. 14-MGU-04-A3663 with MAG Mutual Insurance Agency, LLC.

At all times prior to December 31, 2005, Buyer and its successors or Affiliates shall use commercially reasonable efforts, and cause the Company Group to use commercially reasonable efforts, to obtain and perform the work under the Identified Contracts.

(D) Any amounts released to the Company Stockholders from Contracts Escrow shall be paid to each of the Company Stockholders in accordance with his or her respective Percentage Interests. If the Contracts Escrow is not paid when due

to the Company Stockholders pursuant to this Section 8.2(b)(ii), interest shall accrue on any unpaid amount at the rate of prime plus 1% per annum commencing on the date that payment is due.

(E) In the event there are any funds remaining in the Contracts Escrow on December 31, 2005, because a Succession Event has not occurred with respect to one or more of the Identified Contracts, (and there is no Contracts Escrow Claim Notice, joint directive or dispute pending with respect to such funds), then the Buyer and the Stockholder Representative shall sign a Joint Written Direction (as defined below) instructing the Escrow Agent to release such funds remaining in the Contracts Escrow to the Buyer. Notwithstanding the foregoing, in the event of a dispute as to whether a Succession Event has occurred, then such dispute shall be settled in accordance with Section 8.6(b), and the funds in the Contracts Escrow that relate to the Succession Event shall remain in escrow and not be released to any Party until resolution of the dispute.

(iii) The Company has made a request for equitable adjustment (the “Request”) under the OSSS Subcontract between ▇▇▇▇▇▇ Corporation (“▇▇▇▇▇▇”) and the Company (the “Special Contract”) for the increase in costs as a result of the Collective Bargaining Agreement and Wage Determination in part for the years 2002, 2003, 2004 and that portion of 2005 through May 23, 2005 (which period of costs shall be termed the “Equitable Adjustment”). Seven-Hundred Fifty Thousand Dollars ($750,000) shall be placed in an escrow sub-account (the “Special Contract Escrow”) and shall be to compensate the Buyer for Covered Losses (as defined below) in the event the Equitable Adjustment is not approved in an amount greater than or equal to the Equity Adjustment Threshold. In connection with the Special Contract, the Buyer and its successors or Affiliates shall use commercially reasonable efforts and cause the Company to use commercially reasonable efforts to resolve any issues raised by the contracting officer and to obtain approval of the Equitable Adjustment.

(iv) The Escrow Fund shall not be the sole and exclusive remedy to compensate the Buyer pursuant to the indemnification obligations of the Company Stockholders set forth in Section 8.1(a) provided; however, that the Buyer agrees in all instances to seek recovery from the Escrow Fund, and only if the Escrow Fund is insufficient to cover such claim will the Buyer proceed against the Company Stockholders, and then only to the extent of the insufficiency, and within the limitations of this Agreement, and further provided that the Company Stockholders’ liability shall be limited to Eight Million Seven Hundred Fifty Thousand ($8,750,000).

8.7 Third-Party Claims.

(a) If any claim is instituted by or against a third party with respect to which any Indemnified Person or Seller Indemnitee (an “Indemnified Party”) intends to claim any Damages (a “Third Party Claim”), pursuant to this Article VIII, such Indemnified Party shall promptly notify the Party or Parties from whom indemnification is being claimed (the “Indemnifying Party”) of such claim and, in any event, within fifteen (15) days after receipt by such Indemnified Party of written notice of such Third-Party Claim. Thereafter, the Indemnified Party shall deliver to the Indemnifying Party, within ten (10) days after the Indemnified Party’s receipt thereof, copies of all notices and documents (including court papers) received by the Indemnified Party relating to the Third Party Claims. The notice provided by the Indemnified Party to the Indemnifying Party shall describe the Third Party Claim (the “Asserted Liability”) in reasonable detail and shall indicate the amount (estimated, if necessary, and to the extent feasible) of the Damages that have been or may be suffered by the Indemnified Party. The failure of an Indemnified Party to give any notice required by this Section 8.7(a) shall not affect any of such Party’s rights under this Article VIII or otherwise except and to the extent that such failure is prejudicial to the rights or obligations of the Indemnifying Party.

(b) The Indemnifying Party may elect to defend, at its own expense and with its own counsel reasonably satisfactory to the Indemnified Party, any Asserted Liability, unless the Asserted Liability is one in which: (i) the Third Party asserting the claim is a current, ongoing customer of the Company or the Buyer; (ii) an adverse judgment with respect to the Asserted Liability will establish a precedent materially adverse to the continuing business interests of the Indemnified Party; or (iii) there is a conflict of interest between the Indemnified Party and the Indemnifying Party in the conduct of such defense. If the Indemnifying Party elects to defend the Asserted Liability, the Indemnified Party shall cooperate, at the expense of the Indemnifying Party, in the defense of such Asserted Liability and the Indemnified Party shall not admit any liability with respect to, or settle, compromise or discharge such Third Party Claim.

(c) In any case in which the Indemnified Party retains the defense of the Asserted Liability, the Indemnifying Party may participate in the defense of the Asserted Liability, and neither party shall admit any liability with respect to, or settle, compromise or discharge such Third Party Claim without the other party’s prior written consent, (which consent shall not be unreasonably withheld or delayed).

(d) If the Indemnifying Party chooses to defend or participate in the defense of any Asserted Liability as provided hereunder, the Indemnified Party shall make available to the Indemnifying Party any books, records or other documents within its control that are necessary or appropriate for such defense and shall otherwise cooperate in the defense of such Asserted Liability.

(e) The Indemnified Party may pay, compromise or defend any Asserted Liability in which the Indemnifying Party does not assume or participate in the defense, at the sole cost and expense of the Indemnifying Party if, and to the extent, the Indemnifying Party is determined to be liable for indemnification to the Indemnified Party under this Agreement.

8.8 Limitation. Any indemnification obligations of the Company Stockholders shall be satisfied from any amounts held by the Escrow Agent under the Escrow Agreement prior to Buyer exercising any other remedy, action, claim or offset. No claims for Damages under the General Escrow shall be made until Damages exceed $250,000 and then only to the extent of the amount in excess of $250,000. No individual claim for Damages under the General Escrow will be made unless the Damages equal or exceed $25,000.

8.9 Broker’s Fees.

(a) The Company Stockholders, severally in accordance with their respective Percentage Interests, will indemnify and hold Buyer harmless from any payment alleged to be due for any brokerage or finder’s fee or agent’s commission or other payment in connection with this Agreement to be due by or through the Company or any Company Stockholder as a result of the action of the Company or any Company Stockholder or their officers, employees or agents.

(b) The Buyer will indemnify and hold the Company Stockholders harmless from any payment alleged to be due for any brokerage or finder’s fee or agent’s commission or other payment in connection with this Agreement to be due by or through the Buyer as a result of the action of the Buyer or its officers, employees or agents.

8.10 Subrogation. Upon making an indemnity payment pursuant to this Agreement, the Indemnifying Party will, with the prior written consent of the Indemnified Party, such consent not to be unreasonably withheld, to the extent of such payment, be subrogated to all rights of the Indemnified Party against any third party in respect of the damages to which the payment related. Without limiting the generality of any other provision hereof and subject to the foregoing sentence, each such Indemnified Party and Indemnifying Party will duly execute upon request all instruments reasonably necessary to evidence and perfect the above described subrogation rights.

8.11 No Double Recovery; Use of Insurance. Notwithstanding anything herein to the contrary, no Party shall be entitled to indemnification or reimbursement under any provision of this Agreement for any amount to the extent such Party or its Affiliate has been indemnified or reimbursed for such amount under any other provision of this Agreement, the Exhibits or Disclosure Letter attached hereto, or any document executed in connection with this Agreement or otherwise.

8.12 Treatment of Indemnity Payments Between the Parties. Unless otherwise required by applicable law, all indemnification payments shall constitute adjustments to the Purchase Price for all Tax purposes, and no Party shall take any position inconsistent with such characterization.

9.8 Governing Law. This Agreement shall be governed by and construed in accordance with the internal laws (and not the law of conflicts) of the Commonwealth of Virginia.

9.9 Amendments and Waivers. Except as otherwise provided herein, the Parties may mutually amend any provision of this Agreement at any time prior to Closing. No amendment of any provision of this Agreement shall be valid unless the same shall be in writing and signed by all of the Parties. No waiver by any Party of any default, misrepresentation or

breach of warranty or covenant hereunder, whether intentional or not, shall be deemed to extend to any prior or subsequent default, misrepresentation or breach of warranty or covenant hereunder or affect in any way any rights arising by virtue of any prior or subsequent default, misrepresentation, breach of such warranty or covenant.

9.10 Severability. Any term or provision of this Agreement that is invalid or unenforceable in any situation in any jurisdiction shall not affect the validity or enforceability of the remaining terms and provisions hereof or the validity or enforceability of the offending term or provision in any other situation or in any other jurisdiction. If the final judgment of a court of competent jurisdiction declares that any term or provision hereof is invalid or unenforceable, the Parties agree that the court making the determination of invalidity or unenforceability shall have the power to reduce the scope, duration, or area of the term or provision, to delete specific words or phrases, or to replace any invalid or unenforceable term or provision with a term or provision that is valid and enforceable and that comes closest to expressing the intention of the invalid or unenforceable term or provision, and this Agreement shall be enforceable as so modified after the expiration of the time within which the judgment may be appealed, provided that this Agreement shall not then substantially deprive either Party of the bargained-for performance of the other Party.

9.11 Expenses.

9.13 Employment Agreements; Confidentiality Agreements. The noncompetition and confidentiality provisions of each of the Employment Agreements and Confidentiality Agreements constitute a material part of the purchase and sale transaction contemplated by this Agreement and are supported by adequate consideration. Notwithstanding the foregoing, and any other provisions of this Agreement to the contrary, the obligations of the individual parties under each such agreement shall not constitute an obligation of any other Party to this Agreement, and a breach of any such obligation shall not give rise to any claim for indemnification or recovery of Damages under this Agreement.

9.14 Specific Performance; Remedies. Each Party hereto acknowledges that the other Parties will be irreparably harmed and that there will be no adequate remedy at law for any violation by any of them of any of the covenants or agreements contained in this Agreement, including without limitation, the noncompetition provisions referenced in Section 9.13. It is accordingly agreed that, in addition to any other remedies that may be available upon the breach of any such covenants or agreements, each Party hereto shall have the right to obtain injunctive relief to restrain a breach or threatened breach of, or otherwise to obtain specific performance of, the covenants and agreements contained in this Agreement.

9.15 Construction.

(iv) to employ and obtain the advice of legal counsel, accountants and other professional advisors as the Stockholder Representative, in his sole discretion, deems necessary or advisable in the performance of his duties as the Stockholder Representative and to rely on their advice and counsel, and to pursue or defend any arbitration or litigation arising out of this Agreement;

(v) to incur and pay out of the Purchase Price expenses, including fees of brokers, attorneys and accountants incurred pursuant to the transactions contemplated hereby, and any other fees and expenses allocable or in any way relating to such transaction or any indemnification claim, whether incurred prior or subsequent to Closing;

(vi) to retain up to $100,000 of the Purchase Price as a reserve against the payment of expenses incurred in his capacity as Stockholder Representative with any remaining amount being returned to the Company Stockholders in accordance with their respective Percentage Interests;

(vii) to do or refrain from doing any further act or deed on behalf of the Company Stockholders which the Stockholder Representative deems necessary or appropriate in his sole discretion relating to the subject matter of this Agreement as fully and completely as any of the Company Stockholders could do if personally present and acting;

(viii) to act for such Company Stockholders with respect to all post-Closing matters; and

(ix) to act for such Company Stockholders with respect to all matters regarding the Escrow Agreement.

(b) The appointment of the Stockholder Representative shall be deemed coupled with an interest and shall be irrevocable, and any other person may conclusively and absolutely rely, without inquiry, upon any actions of the Stockholder Representative as the acts of the Company Stockholders in all matters referred to in this Agreement. Each of the Company Stockholders hereby ratifies and confirms all that the Stockholder Representative shall do or cause to be done by virtue of such Stockholder Representative’s appointment as Stockholder Representative of such Company Stockholder. The Stockholder Representative shall act for the Company Stockholders on all of the matters set forth in this Agreement in the manner the Stockholder Representative believes to be in the best interest of the Company Stockholders, but the Stockholder Representative shall not be responsible to any Company Stockholders for any loss or damage any Company Stockholders may suffer by reason of the performance by the Stockholder Representative of such Stockholder Representative’s duties under this Agreement, other than loss or damage arising from willful misconduct in the performance of such Stockholder Representative’s duties under this Agreement.

(c) Each of the Company Stockholders hereby expressly acknowledges and agrees that the Stockholder Representative is authorized to act on behalf of such Company Stockholder notwithstanding any dispute or disagreement among the Company Stockholders, and that any person shall be entitled to rely on any and all action taken by the Stockholder Representative under this Agreement without liability to, or obligation to inquire of, any of the Company Stockholders. If the Stockholder Representative resigns or ceases to function in such capacity for any reason whatsoever, then the successor Stockholder Representative shall be the person which the Company Stockholders which held a majority of the Company Stock at Closing appoint; provided, however, that if for any reason no successor has been appointed within thirty (30) days, then any Company Stockholder shall have the right to petition a court of competent jurisdiction for appointment of a successor Stockholder Representative. The Company Stockholders do hereby jointly and severally agree to indemnify and hold the Stockholder Representative harmless from and against any and all liability, loss, cost, damage or expense (including without limitation attorneys’ fees) reasonably incurred or suffered as a result of the performance of such Stockholder Representative’s duties under this Agreement except for any such liability arising out of the willful misconduct of the Stockholder Representative.

(d) The amount of One Hundred Thousand Dollars ($100,000) of the Purchase Price which is to be disbursed at Closing to the Stockholder Representative shall be placed into an interest-bearing account (the “Disbursement Account”) and used by the Stockholder Representative to pay out-of-pocket expenses related or incident to his duties hereunder including, but not limited to, legal fees, accounting fees, out-of-pocket expenses, and liabilities or obligations of the Company Stockholders pursuant to this Agreement, the Escrow Agreement, or

any of the other documents executed by all Company Stockholders at Closing. These expenses, liabilities and obligations are hereafter collectively referred to as “Post-Closing Obligations.” Any and all distributions or payments from the Disbursement Account shall be made only by check executed by the Stockholder Representative. The Stockholder Representative shall prepare and provide at any Company Stockholder’s request, but not more than quarterly, reports to the Company Stockholders which indicate and describe all disbursements from the Disbursement Account and anticipated disbursements and claims known by the Stockholder Representative relating to Post-Closing Obligations.

(e) If the funds in the Disbursement Account are disbursed to the extent that remaining funds are less than Five Thousand Dollars ($5,000), the Stockholder Representative may request additional amounts from the Company Stockholders to pay present or future Post-Closing Obligations to be placed into the Disbursement Account in increments of at least Five Thousand Dollars ($5,000). The Company Stockholders each agree to pay promptly to Stockholder Representative his Proportional Share of any further amounts requested for the Disbursement Account or any Post-Closing Obligations. “Proportional Share” shall mean the total amount requested or otherwise required hereunder multiplied by the Percentage Interest of each Company Stockholder as listed on Exhibit A. The Stockholder Representative shall notify each of the Company Stockholders of any additional amounts requested or required for the Disbursement Account or any Post-Closing Obligation and the amount to be paid by that Company Stockholder. Payment of such amount shall be made, as directed in such notice, within ten (10) days of each Company Stockholder’s receipt thereof. In the event that any Company Stockholder fails to pay his Proportionate Share within ten (10) days after receipt of Stockholder Representative’s notice (hereinafter, the “Defaulting Stockholder”), the Stockholder Representative shall have the right to seek payment of such amount from each Defaulting Stockholder and to also recover interest at the rate of seven percent (7%) per annum accruing from the date that payment was required and reasonable attorneys fees and costs incurred by Stockholder Representative in connection with the collection of unpaid amounts from a Defaulting Stockholder. Further, the remaining Company Stockholders (or any one or more of them) may, at their discretion, pay the Defaulting Stockholder’s Proportionate Share and shall have the full right of contribution and indemnification to obtain repayment of amounts advanced plus interest at the rate of seven percent (7%) per annum and reasonable attorneys fees and costs from any Defaulting Stockholder.

(f) If Buyer or an Indemnified Person for any reason pursues or asserts a cause of action or other claim against any one or more Company Stockholders for a Post-Closing Obligation for which the Company Stockholders are jointly and severally liable under this Agreement, and any such Company Stockholder pays funds to the Buyer or an Indemnified Person in excess of his Proportionate Share of such claim, each remaining Company Stockholder agrees to contribute his Proportionate Share of any fees, costs, expenses, judgments, or other liabilities (including reasonable attorney’s fees) arising out of the cause of action or other claim within ten (10) days of notice of a request for contribution. Interest shall accrue on any amount not contributed by a Company Stockholder when required hereunder at the rate of seven percent (7%) per annum from the date that a contribution payment is due. Any Company Stockholder

who enforces such right of contribution may recover from a Defaulting Stockholder reasonable attorneys fees and costs related to such enforcement.

(g) Each Company Stockholder agrees to indemnify and hold harmless each of the other Company Stockholders for any liability, damage, expense or loss (including reasonable attorneys’ fees and enforcement costs) which may arise as a result of the breach or default by such Company Stockholder of any provision of this Section 9.18.

(h) The provisions of this Section 9.18 shall terminate at such time as all obligations or liabilities of the Company Stockholders under this Agreement, the Escrow Agreement and other documents executed by all Company Stockholders at Closing have been terminated, satisfied or resolved. Upon the termination hereof, any amounts remaining in the Disbursement Account shall be disbursed to the Company Stockholders according to their Proportionate Interest.
