ARTICLE I
STOCK PURCHASE

1.1           Stock Purchase. On the terms and subject to the conditions of this Agreement, the Buyer agrees to purchase from each of the Sellers, and each of the Sellers agrees to sell to the Buyer, the Shares owned by such Seller, free and clear of all Encumbrances, which Shares collectively constitute and shall constitute as of the Closing Date all of the issued and outstanding shares of the capital stock of the Company, for the consideration specified in Section 1.2.

($60,000,000), subject to adjustment as set forth in this Agreement. The Purchase Price shall be comprised of (i) an amount to be paid in cash at Closing as per the flow of fund memorandum, plus (ii) post-Closing payments in cash equal to Fifty-Four Million Dollars ($54,000,000), in the aggregate, less any amount paid in cash at Closing, as adjusted pursuant to Section 1.4 hereof and as reduced by the amount of the Aggregate Restricted Stock Repurchase Payments (the “First Post-Closing Payment”), and (iii) post-Closing payments in cash equal to Six Million Dollars ($6,000,000), in the aggregate, as adjusted pursuant to the terms and conditions hereof (the “Second Post-Closing Payment”). Subject to the terms and conditions of this Agreement, at the Closing, each Seller shall have the right to receive, with respect to each of his or her shares of Company Common Stock issued and outstanding immediately prior to the Closing, (i) in accordance with this Section 1.2(a), an amount in cash equal to the First Per Share Post-Closing Amount, plus (ii) in accordance with Section 1.3 hereof, an amount in cash equal to the Second Per Share Post-Closing Amount.

As of the Closing, the Restricted Stock Plan and all Restricted Stock Awards granted by the Company pursuant to the Restricted Stock Plan or otherwise shall have been terminated and cancelled. The Company shall terminate the Restricted Stock Plan and all other equity-related plans prior to the Closing, and neither Buyer nor the Company shall have any Liability thereunder. The Company agrees that, pursuant to this Section 1.5, (a) the Company and each Restricted Stock Participant (other than Cindy A.

The Company shall not amend or terminate any Restricted Stock Repurchase Agreement, or waive any provision thereof, without the Buyer’s prior written consent. The Company shall execute or cause to be executed such further documents, assignments and assurances, and take or cause to be taken such further actions, as may reasonably be requested by the Buyer to consummate the closings under each Restricted Stock Repurchase Agreement and the transactions contemplated thereby with each Restricted Stock Participant (other than Cindy A. Andre). Subject to the terms and conditions hereof, the shares of Company Common Stock subject to the Restricted Stock Award granted to Cindy A. Andre shall be purchased pursuant to Section 1.2 above.

1.6           Post-Closing Adjustment.

(a)           Within seventy-five (75) days following the Closing Date, the Buyer shall furnish the Seller Representative with a balance sheet of the Company as of the Closing Date on a post-Closing basis (the “Closing Balance Sheet”) prepared in accordance with Modified GAAP, which shall set forth the Closing Working Capital of the Company, the Indebtedness for Borrowed Money, the Non-Ordinary Course Liabilities and, as applicable, the Closing Working Capital Deficit or the Closing Working Capital Surplus (collectively, the “Closing Adjustments”). Each Seller shall assist the Buyer in the preparation of the Closing Balance Sheet if reasonably requested by the Buyer.

(b)           The Seller Representative shall have a period of fifteen (15) days after receipt of the Closing Balance Sheet to notify the Buyer of its election to accept or reject the Closing Balance Sheet. In the case of a rejection, such notice must contain the reasons for such rejection in reasonable detail and must set forth the amount of the requested adjustment (or a reasonable estimate thereof). In the event no notice is received by the Buyer during such fifteen (15) day period, the Closing Balance Sheet and any required adjustments resulting therefrom shall be deemed accepted by the Seller Representative and the Sellers and final and binding on the Parties hereto. In the event that the Seller Representative shall timely reject the Closing Balance Sheet, the Buyer and the Seller Representative shall promptly (and in any event within thirty (30) days following the date upon which the Seller Representative shall reject the Closing Balance Sheet), attempt to make a joint determination of the Closing Adjustments and such determination and any required adjustments resulting therefrom shall be final and binding on the Parties hereto solely for purposes of this Section 1.6.

4

(c)           In the event the Seller Representative and the Buyer shall be unable to agree upon a joint determination of Closing Adjustments within one hundred twenty (120) days from the Closing Date, then within one hundred thirty (130) days from the Closing Date, the Buyer and the Seller Representative shall submit the dispute to the Accounting Firm. The Buyer and the Seller Representative shall request that the Accounting Firm render its determination prior to the expiration of one hundred sixty (160) days from the Closing Date and such determination and any required adjustments resulting therefrom shall be final and binding on all the Parties hereto solely for purposes of this Section 1.6. The fees and expenses of the Accounting Firm shall be allocated to be paid by the Buyer and/or the Sellers, respectively, based upon the percentage which the portion of the total amount contested and not awarded to such party bears to the total amount contested, as determined by the Accounting Firm. Nothing stated or disclosed in the Closing Balance Sheet or in connection with the determination thereof shall waive or be deemed to waive any inaccuracy or breach of any representation or warranty made by the Company or any Seller or any right to indemnification hereunder and shall be without prejudice to any other right or remedy of the Buyer under this Agreement, at equity or at law.

(d)           If the Closing Working Capital as finally determined in accordance with the provisions of this Section 1.6 is less than the Estimated Working Capital, then the amount of the difference shall be paid by the Sellers to the Buyer, in proportion to their respective First Per Share Post-Closing Amounts, as an adjustment to the Purchase Price by wire transfer in immediately available funds within seven (7) days after such determination. If the Closing Working Capital as finally determined in accordance with the provisions of this Section 1.6 is more than the Estimated Working Capital, then the amount of the difference shall be paid by the Buyer to the Sellers as an adjustment to the Purchase Price by wire transfer in immediately available funds in proportion to their respective First Per Share Post-Closing Amounts within seven (7) days after such determination.

(e)           If the Indebtedness for Borrowed Money and/or the Non-Ordinary Course Liabilities determined pursuant to this Section 1.6 exceed the Indebtedness for Borrowed Money and/or the Non-Ordinary Course Liabilities, respectively, set forth on the Estimated Closing Balance Sheet, such excess shall be paid as an adjustment to the First Post-Closing Payment by the Sellers to the Buyer by wire transfer in immediately available funds within seven (7) days after such determination. If the Indebtedness for Borrowed Money and/or the Non-Ordinary Course Liabilities determined pursuant to this Section 1.6 are less than the Indebtedness for Borrowed Money and/or the Non-Ordinary Course Liabilities, respectively, set forth on the Estimated Closing Balance Sheet, such deficit shall be paid as an adjustment to the First Post-Closing Payment by the Buyer to the Sellers, in proportion to their respective First Per Share Post-Closing Amounts, by wire transfer in immediately available funds within seven (7) days after such determination. The adjustments described in Sections 1.6(d) and (e) shall be referred to collectively as the “Post-Closing Adjustment”. If either Party does not so pay to the other Party by the due date, such amounts shall be deemed Damages under Article IX hereof which shall be paid in full without regard to the limitations set forth in Sections 9.4 and 9.5 hereof.

1.7           Stock Options and Warrants. Prior to the Closing, the Sellers shall cause the Company to terminate and cancel any options to purchase Company Common Stock (“Company Stock Options”) and any warrants to purchase Company Common Stock (“Company Warrants”).

5

Buyer shall neither assume any options or warrants nor be required by the terms of this Agreement to replace any options or warrants with comparable options or warrants. The Company shall terminate all stock option plans and other stock or equity-related plans of the Company prior to the Closing, and neither Buyer nor the Company shall have any liability or obligation thereunder. No adjustment shall be made in the Purchase Price paid in the Stock Purchase as a result of any cash proceeds received by the Company from the date hereof to the Closing Date pursuant to the exercise of options, warrants or other rights to acquire or receive Company Common Stock.

1.8           Withholding of Tax. Buyer will be entitled (but not obligated) to deduct and withhold from the consideration otherwise payable pursuant to this Agreement to any holder of Company Common Stock such amounts as Buyer (or any Affiliate thereof) shall determine in good faith that they are required to deduct and withhold with respect to the making of such payment under the Code or any provision of federal, state, local or foreign Tax Law. To the extent that amounts are so withheld by Buyer, such withheld amounts will be treated for all purposes of this Agreement as having been paid to the holder of the Company Common Stock in respect of whom such deduction and withholding were made by Buyer.

1.9           Lost, Stolen or Destroyed Certificates. In the event any certificates representing outstanding shares of Company Common Stock shall have been lost, stolen or destroyed, Buyer shall pay in exchange for such lost, stolen or destroyed certificates, upon the making of an affidavit of that fact by the holder thereof, the applicable Purchase Price; provided, however, that Buyer may, in its discretion and as a condition precedent to the payment thereof, require the holder of such lost, stolen or destroyed certificates to deliver a bond in such sum as Buyer may reasonably direct as indemnity against any claim that may be made against Buyer with respect to the certificates alleged to have been lost, stolen or destroyed.

6.3                                 Publicity and Disclosure. The Buyer and the Company shall agree with each other as to the form and substance of any press release, publicity or other communication related to this Agreement or the transactions contemplated hereby. No Party shall make any disclosure of this Agreement or the existence, terms and conditions hereof (whether or not in response to an inquiry about the existence or subject matter of this Agreement) to any Person unless previously approved by the Buyer. Notwithstanding the foregoing, nothing contained herein shall prohibit the Buyer from making any disclosure which the Buyer in good faith believes is required by, or advisable according to, applicable Laws, regulations or stock market rules, after using reasonable efforts to give notice to the Seller Representative and an opportunity to comment on such disclosure.

34

6.4                                 No Solicitation; No Trading.

(a)                                  The Company and each Seller shall not, and shall not authorize or knowingly permit any director, trustee, officer, employee, consultant, agent or any representative thereof, including without limitation, any broker disclosed in Article III or Article IV hereof (collectively, “Representatives”), to, during the period commencing on the date of this Agreement and ending with the earlier to occur of the Closing or the termination of this Agreement in accordance with its terms, directly or indirectly:  (a) solicit, accept, approve, encourage (including by way of furnishing information), initiate, or respond to the submission of proposals or offers from any Person for, (b) participate in any discussions or negotiations pertaining to, or (c) furnish any information to any Person, other than the Buyer, relating to, any acquisition or purchase of all or a material amount of the assets of, or any equity interest in, the Company or a merger, consolidation or business combination involving the Company. The Company and each Seller shall discontinue any and all negotiations with any Person with whom any of them is currently engaged regarding any of the above. If the Company or any Seller receives any unsolicited offer or proposal relating to any of the above, the Company or such Seller shall promptly notify the Buyer thereof, including the identity of the party making such offer or proposal and the specific terms of such offer or proposal, and provide the Buyer with a copy thereof.

(b)                                 The Company and each of the Sellers acknowledge and agree that each is aware (and that each of their respective Representatives is aware or, upon receipt of any material nonpublic information of Buyer, will be advised) of the restrictions imposed by the United States federal securities laws and other applicable foreign and domestic laws on a Person possessing material nonpublic information about a public company. The Company and each of the Sellers hereby agree that while any of them are in possession of such material nonpublic information, none of such Person or Persons shall purchase or sell any securities of the Buyer, communicate such information to any third parties, take any other action in violation of such laws, or cause or encourage any third party to do any of the foregoing.

6.5                                 Notification of Certain Matters. The Company and the Sellers shall give prompt notice to the Buyer of (a) the occurrence or non-occurrence of any event the occurrence or non-occurrence of which would be likely to cause any representation or warranty of the Company or the Seller contained herein to be untrue or inaccurate in any material respect at or prior to the Closing and (b) any material failure of the Company or any Seller to comply with or satisfy any covenant, condition or agreement to be complied with or satisfied by the Company or any Seller hereunder. The delivery of any notice pursuant to this Section 6.5 shall not, without the express written consent of the Buyer, be deemed to (x) modify the representations or warranties hereunder of the Company or any Seller, (y) modify the conditions set forth in Article VII or (z) limit or otherwise affect the remedies available hereunder to the Buyer.

6.6                                 Tax Matters.

(a)                                  Post-Closing Tax Returns; Tax Indemnity. Buyer shall properly and accurately prepare (or cause to be prepared) and file (or cause to be filed) each Tax Return required to be filed by the Company after the Closing Date for a taxable period beginning before the Closing Date, provided that if requested by Seller Representative, Buyer shall make

35

commercially reasonable efforts to engage Watkins, Meegan, Drury & Company, L.L.C. to prepare the income Tax Returns of the Company for any taxable period ending on or before the Closing Date. To the extent any Tax shown as due on such Tax Return is payable by any Seller (taking into account indemnification obligations hereunder), (i) such Tax Return shall be prepared in a manner consistent with the prior practice of the Company, unless otherwise required by applicable Tax Laws; (ii) such Tax Return shall be provided to the Seller Representative at least twenty (20) days prior to the due date for filing such return (or, if required to be filed within twenty (20) days of the Closing or within forty-five (45) days of the end of the taxable period to which such Tax Return relates, as soon as possible following the Closing or the end of the taxable period, respectively); and (iii) the Seller Representative shall have the right to review and comment on such Tax Return and Buyer and Seller Representative shall cooperate to resolve any disagreements regarding reporting positions to be taken in such Tax Returns. In the case of a disagreement concerning a reporting position that is not controlled by clause (i) of Section 6.6(a)(i) above, Seller Representative may select the reporting position with respect to such matter if (w) there is substantial authority for such position within the meaning of Section 6662 of the Code, (x) no reserve for Tax liability would be required to be established in the financial statements relating to the Buyer or the Company as a result of potential Tax liability that is not shown as due on such Tax Return, (y) such reporting position will not be binding on the Buyer or the Company in the preparation of Tax Returns in any taxable period ending after the Closing Date and (z) adequate security (determined within the sole reasonable discretion of Buyer) is provided to the Buyer to secure the indemnification obligations of the Sellers under Section 9.1(a)(vii) for Damages which could result from the failure to sustain such Tax reporting position. Pursuant to Section 9.1(a)(vii), promptly upon request by Buyer, the Sellers shall pay to the applicable Buyer Indemnified Party the amount of any Taxes paid or required to be paid by the Company that are attributable to any taxable period beginning on or before the Closing Date; provided, however, that with respect to a taxable period ending after the Closing Date, such indemnity shall be limited to the Taxes attributable to the portion of such period ending on the Closing Date as described in Section 6.6(b). For avoidance of doubt, all Taxes attributable to the Section 338(h)(10) Elections shall be considered to be allocable to the taxable period or portion thereof ending on the Closing Date, and subject to the foregoing indemnification by the Sellers. To the extent permitted by applicable law, the Sellers shall include any income, gain, loss, deduction or other Tax items for such periods on their Tax Returns in a manner consistent with the Schedule K-1s filed with the Tax Returns of the Company filed pursuant to this Section 6.6. The Buyer shall prepare (or cause to be prepared) and file (or cause to be filed) each Tax Return required to be filed by the Company after the Closing Date for a taxable period beginning after the Closing Date, and pay (or cause to be paid) all Taxes required to be paid by the Company with respect to any taxable period beginning after the Closing Date; provided that the Buyer’s obligations to prepare and file such Tax Returns and pay such Taxes shall not prevent recovery of Damages to which any Indemnified Party is entitled under Section 9.1 in connection therewith.

(b)                                 Allocation of Taxes. The Sellers, the Buyer and the Company shall, to the extent permitted by applicable law, cause the taxable period of the Company to end as of the close of the Closing Date. The Buyer shall not cause the Company to take any actions on the Closing Date after the Closing that are out of the ordinary course of business, except as contemplated by this Agreement. For purposes of this Agreement, Company Taxes incurred with respect to a taxable period that includes but does not end on the Closing Date, shall be

36

allocated to the portion of the period ending on the Closing Date (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 feasibly allocable to specific transactions or events, in proportion to the number of days in such period occurring before the Closing Date compared to the total number of days in such 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 (for the elimination of doubt, Taxes incurred by reason of the transactions contemplated by this Agreement shall be allocated to the portion of the period ending on the Closing Date). Any credits relating to a taxable period that begins before and ends after the Closing Date shall be taken into account as though 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 practices of the Company.

(c)                                  Transfer Taxes, Etc. Notwithstanding any provision to the contrary in this Agreement, all Transfer Taxes incurred by Sellers in connection with the transactions contemplated by this Agreement shall be paid by the Sellers when due. The Sellers shall, at their own expense, file all necessary Tax Returns and other documentation with respect to all such Transfer Taxes. If required by applicable law, the Buyer shall, and shall cause its Affiliates to, join in the execution of any such Tax Returns and other documentation.

(d)                                 Tax Elections; Amended Returns. Except in connection with an audit resolved pursuant to Section 6.6(h) of this Agreement, no Party may amend a Tax Return of the Company, or file or amend any Tax election of the Company, in each case, with respect to a taxable period beginning before the Closing Date without the consent of the other Parties, which consent shall not be unreasonably withheld or delayed.

(e)                                  Cooperation, Access to Information, and Record Retention. The Sellers, the Company and the Buyer shall cooperate, and shall cause their representatives to cooperate, as and to the extent reasonably requested by any other Party hereto in connection the preparation and filing of Tax Returns as provided herein and any audit, litigation or other proceeding with respect to Taxes. Such cooperation shall include the provision of records and information which are reasonably relevant to any such Tax Return, 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 Sellers, the Buyer and the Company shall (i) retain all books and records with respect to Company Taxes (including Tax Returns) relating to any taxable period beginning before the Closing Date until the expiration of the statute of limitations for assessment of Taxes for such respective taxable period and (ii) give the other Parties hereto reasonable written notice prior to transferring, destroying or discarding any such books and records and, if another Party so requests, allow the other Party to take possession of such books and records.

(f)                                    Tax Certificates, Etc. The Parties further agree, upon request, to use reasonable efforts to obtain any certificate or other document from any Government Authority or any other Person as may be necessary to mitigate, reduce or eliminate any Tax that could be imposed.

37

(g)                                 Termination of Tax Sharing Agreements. All Tax sharing agreements or similar agreements with respect to or involving the Company (other than any such agreement created by the execution of this Agreement) shall be terminated as of the Closing Date and, after the Closing Date, the Company shall not be bound thereby or have any Liability thereunder.

(h)                                 Tax Proceedings. Any Party who receives any notice of a pending or threatened Tax audit, assessment, or adjustment against or with respect to the Company which may give rise to Liability of another Party hereto (including pursuant to the indemnification provisions of this Agreement), shall promptly notify such other Party 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 which could reasonably be a basis for a claim pursuant to the indemnity obligations hereunder. The Seller 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 its choice, but reasonably satisfactory to Buyer, at the Sellers’ expense, but only to the extent such audit or other proceeding pertains to Tax periods ending on or before the Closing Date. 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 Sellers (including any indemnity obligation under this Agreement). Both the Buyer and the Sellers (through the Seller Representative) shall be entitled to represent their respective 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 Tax period that includes but does not end on the Closing Date. Notwithstanding the foregoing provisions of this Section 6.6, the Seller Representative shall not, without the Buyer’s consent, agree to any settlement with respect to any Tax if such settlement could adversely affect any Tax Liability of the Buyer, any Affiliate of the Buyer, or (with respect to any taxable period (or portion thereof) beginning after the Closing Date) the Company. Except as provided in this Section 6.6 the provisions of Article IX including the provisions therein addressing settlement authority, shall govern the manner in which Tax audit or administrative or judicial proceedings are resolved.

(i)                                     Section 338(h)(10) Elections. The Sellers will join with the Buyer in making an election under Section 338(h)(10) of the Code (and any corresponding elections under state or local Tax law) (collectively, the “Section 338(h)(10) Elections”) with respect to the Stock Purchase under this Agreement. The Buyer shall be responsible for the timely and accurate preparation and filing of all forms and documents required in connection with the Section 338(h)(10) Elections and shall provide the Sellers with properly completed copies of Form 8023 (and any corresponding state or local Tax forms) prior to the Closing Date. The Sellers agree to execute and deliver to the Buyer on the Closing Date any such forms that are or have been provided by the Buyer for execution and to promptly execute such other forms as may be reasonably requested by the Buyer thereafter in connection with making or perfecting the Section 338(h)(10) Elections. The Parties shall cooperate fully with each other and make available to each other such Tax data and other information as may be reasonably required by the Buyer or the Sellers in order to timely file the Section 338(h)(10) Elections. The Company and Sellers shall not revoke the Company’s election to be taxed as an S corporation within the meaning of Sections 1361 and 1362 of the Code. The Company and the Sellers shall not take or

38

allow any action other than the Stock Purchase pursuant to this Agreement that would result in the termination of the Company’s status as a validly electing S corporation within the meaning of Sections 1361 and 1362 of the Code.

(j)                                     Purchase Price Allocation. The Parties agree that the consideration to be paid pursuant to Article I of this Agreement and other items properly includible in the deemed sales price of the assets of the Company pursuant to the Section 338(h)(10) Elections shall be allocated, for Tax purposes, among the Company’s assets in a manner consistent with the provisions of Section 338 and Section 1060 of the Code and all regulations promulgated thereunder. The Buyer shall prepare IRS Form 8883 for inclusion with the federal income Tax Return of the Company ending on the Closing Date and any similar allocation required under state, local, or foreign law (collectively, “IRS Form 8883”). The Buyer shall permit the Seller Representative to review and comment on IRS Form 8883. The Company, the Sellers and the Buyer agree to report this transaction for federal Tax purposes as a valid election under Section 338(h)(10) of the Code and in accordance with IRS Form 8883 as ultimately filed, and shall not take any position or action inconsistent therewith upon examination of any Tax Return, in any refund claim, in any litigation, investigation or otherwise; provided, however, that if, in any audit of any Tax Return of the Sellers, the Company or the Buyer by a Government Authority, the fair market values are finally determined to be different from IRS Form 8883, as adjusted, the Buyer, the Company and the Sellers may (but shall not be obligated to) take any position or action consistent with the fair market values as finally determined in such audit. Schedule 6.6(j) sets forth the fair market value of the assets of the Company that the Parties agree will be used to allocate such consideration.

(k)                                  Characterization of Indemnity Payments. The Buyer and the Sellers agree to treat any payment made by the Sellers to the Buyer hereunder as an adjustment to the Purchase Price.

6.7                                 Litigation Support. In the event and for so long as any Party actively is contesting or defending against any charge, complaint, action, suit, audit, proceeding, hearing, investigation, claim, or demand in connection with (i) any transaction contemplated under this Agreement or (ii) any fact, situation, circumstance, status, condition, activity, practice, plan, occurrence, event, incident, action, failure to act, or transaction on or prior to the Closing Date involving the Company, each of the other Parties will cooperate with such Party or its counsel in the contest or defense, make available its personnel, and provide such testimony and access to its books and records as shall be necessary in connection with the contest or defense, all at the sole cost and expense of the contesting or defending Party (unless the contesting or defending Party is entitled to indemnification therefor under Article IX below).

6.8                                 Reasonable Efforts. Each Party agrees to use all reasonable efforts promptly to take, or cause to be taken, all actions and do or cause to be done all things necessary, proper or advisable under applicable Laws to (a) obtain all consents, approvals or actions of, make all filings with and give all notices to Government Authorities or any other Person required to consummate the Stock Purchase and the other matters contemplated hereby, (b) provide such other information and communications to such Government Authorities or other public or private Persons as the other Party or such Government Authorities or other public or private Persons may reasonably request in connection therewith, and (c) execute such further documents, deeds,

39

bills of sale, assignments and assurances and take such further actions as may reasonably be required to consummate and make effective the transactions contemplated by this Agreement including the satisfaction of all conditions hereto. If applicable, the Parties shall file all notices and other information and documents required under the Hart-Scott-Rodino Antitrust Improvement Act of 1976, as amended, as promptly as practicable after the date hereof.

6.9                                 Payment of Obligations. Prior to the Closing, each Seller and each of the officers, directors, employees and Affiliates of the Company shall repay in full, in accordance with their terms, all debts and other obligations, if any, owed to the Company (except that, with respect to the promissory note evidencing Cindy A. Andre’s obligation to reimburse the Company for the withholding Tax related to the grant to her of a Restricted Stock Award, Cindy A. Andre shall repay the amounts due under such promissory note in full on the first business day following the Closing by directing Buyer to pay to the Company, out of the First Per Share Post-Closing Payments to be paid to her, an amount equal to the amount payable to the Company under such promissory note).

6.10                           Company Employees. Each of the Company and the Sellers agrees that promptly after the date hereof it shall allow the Buyer to make a presentation to the Company Employees and to interview such employees for continued employment with the Company after the Closing. Each of the Company and the Sellers will use all reasonable efforts to cause such Company’s employees to make available their employment services to the Company after the Closing.

6.11                           Further Assurances. Each Seller and the Company will, either prior to or after the Closing, execute such further documents, deeds, bills of sale, assignments and assurances and take such further actions as may reasonably be required by Buyer to consummate the Stock Purchase, to vest the Buyer with full title to all capital stock of the Company and all assets, properties, privileges, rights, approvals, immunities and franchises of the Company and its business or to effect the other purposes of this Agreement.

6.12                           Benefit Plans. Upon Buyer’s request, the Company shall take action prior to the Closing Date to terminate the Benefit Plans that it sponsors and to withdraw Company Employees from participation in any Benefit Plans that it does not sponsor. The Buyer expects to review the total compensation and benefits that the Company Employees have received as employees of the Company before the Closing. From and after the Closing Date, the Buyer will make available to continuing Company Employees a package of compensation and employee benefits that in the aggregate are substantially similar to that made available to the Buyer’s own similarly-situated employees; provided, however, that the Buyer shall in no event be obligated to provide any particular benefit to such Company Employees and shall retain full discretion to modify, amend, or terminate any of the benefits it makes available. Nothing in this Agreement shall be construed to create a right in any Company Employee to employment with the Company, the Buyer or any of its subsidiaries, and, subject to any written agreement between a Company Employee and the Company, the Buyer or any of its subsidiaries, the employment of each Company Employee who continues employment with the Company, the Buyer or any of its subsidiaries after the Closing Date shall be “at will” employment.

6.13                           Seller Waiver and Termination. For the benefit of the Buyer, each of the Sellers and the Company hereby waive (and none shall be of any further force or effect) all provisions of

40

Section 13.1-651 of the VSCA with respect to this Agreement and the transactions contemplated hereby.

6.14                           Disclosure Schedules.

(a)                            The Disclosure Schedules shall be arranged by the Sellers in paragraphs corresponding to the subsections contained herein. Nothing in the Disclosure Schedules shall be deemed to disclose an exception to any representation or warranty made in Article III unless it describes the relevant facts in such reasonable detail as the context requires. A fact or matter disclosed in the Disclosure Schedules with respect to one section or subsection shall be deemed to be disclosed with respect to each other section or subsection where such disclosure is appropriate to the extent it is clear from reading the face of such Disclosure Schedule (and not any other agreement or other document referred to therein or attached thereto) that such disclosure is applicable to such other sections or subsections of the Disclosure Schedules and provided that an agreement or other document which is merely listed or identified in any section or subsection of the Disclosure Schedules shall not be deemed to be disclosure with respect to any other section or subsection of the Disclosure Schedules.

(b)                           To the extent that any matter arises or comes into existence between the date hereof and the Closing that is required to be described by the Company or Sellers in the Seller Disclosure Schedules in order for such schedules to be true, correct and complete in all material respects at and as of the Closing, it is understood and agreed that, from time to time prior to the Closing, the Seller Representative may propose to amend, supplement or revise the Seller Disclosure Schedules with respect to any such matter. If the Buyer reasonably determines that an amendment, supplement or revision proposed by the Seller Representative satisfies the terms and conditions of this Section 6.14, such amendment, supplement or revision shall be effective for purposes of the indemnification obligations set forth in Section 9.1(a)(i) with respect to representations made at the Closing, but shall in no way be effective for purposes of amending, supplementing or revising any representation made as of the date hereof, or otherwise curing any misrepresentation made as of the date hereof, and shall be disregarded for purposes of Section 7.1 and Section 11.1(a)(iii).

(c)                            To the extent that any matter arises or comes into existence between the date hereof and the Closing that is required to be described by the Buyer in the Buyer Disclosure Schedules in order for such schedules to be true, correct and complete in all material respects at and as of the Closing, it is understood and agreed that, from time to time prior to the Closing, the Buyer may propose to amend, supplement or revise the Buyer Disclosure Schedules with respect to any such matter. If the Seller Representative reasonably determines that an amendment, supplement or revision proposed by the Buyer satisfies the terms and conditions of this Section 6.14, such amendment, supplement or revision shall be effective for purposes of the indemnification obligations set forth in Section 9.1(b)(i) with respect to representations made at the Closing, but shall in no way be effective for purposes of amending, supplementing or revising any representation made as of the date hereof, or otherwise curing any misrepresentation made as of the date hereof, and shall be disregarded for purposes of Section 8.1 and Section 11.1(a)(i).

6.15                           Selected AR. If the Buyer actually collects any portion of the Selected AR after the Closing and on or before the first (1st) anniversary of the Closing Date, Buyer shall be

41

obligated to pay the Per Share Selected AR Amount to each Seller, with respect to each of his or her shares of Company Common Stock issued and outstanding immediately prior to the Closing. Such payment, if any, shall be made in cash by the delivery of immediately available funds on a quarterly basis ending on the first (1st) anniversary of the Closing Date.

ARTICLE VII

7.1                                 Representations and Warranties True at the Closing Date.

ARTICLE IX
INDEMNITY

9.1                                 General Indemnification.

(a)                                  Each Seller, jointly and severally, covenants and agrees to indemnify, defend, protect and hold harmless the Buyer Indemnified Parties from, against and in respect of all Damages suffered, sustained, incurred or paid by any Buyer Indemnified Party, in each case in connection with, resulting from or arising out of, directly or indirectly (whether or not involving a third party claim):  (i) the inaccuracy or breach of any representation or warranty made by the Company or any Seller set forth in this Agreement or in any other agreement or any certificate delivered or provided in connection with or related to the consummation of the transactions contemplated by this Agreement; (ii) the nonfulfillment of any covenant or agreement on the part of the Company or any Seller set forth in this Agreement or in any agreement or certificate executed and delivered by the Company or any Seller pursuant to this Agreement or in the transactions contemplated hereby; (iii) any Liabilities which arise out of, relate to or are associated with the Restricted Stock Plan, any Restricted Stock Award or any repurchase under any Restricted Stock Repurchase Agreement; (iv) any Liability with respect to any matter or matters described on Appendix C; (v) the Benefit Plans and any and all benefits accrued under the Benefit Plans as of the Closing Date and any and all other Liabilities arising out of, or in connection with the form or operation of the Benefit Plans on or prior to the Closing Date; (vi) any and all Liabilities resulting from any litigation, suit, proceeding, action, claim, demand or investigation pending or threatened against the Company which arises out of the operations of the Company on or prior to the Closing Date including, without limitation, any such matter listed on Schedule 3.13; and (vii) any and all Liabilities for Taxes (x) in connection with or arising out of the Company’s activities or business on or prior to the Closing Date (determined, with respect to Tax periods that begin before and end after the Closing Date, in accordance with the allocation provisions of Section 6.6(b)) in excess of the amount of such Taxes reflected as a current liability in the computation of Closing Working Capital, or (y) owing by any Person other than the Company for which the Company may be liable, including, without limitation (A) under Treasury Regulation Section 1.1502-6 (or any similar provision of state, local, or foreign law), (B) as a transferee or successor, or (C) by contract.

(b)                                 The Buyer covenants and agrees to indemnify, defend, protect and hold harmless the Seller Indemnified Parties from, against and in respect of all Damages suffered, sustained, incurred or paid by any Seller Indemnified Party, in each case in connection with,

46

resulting from or arising out of, directly or indirectly (whether or not involving a third party claim):  (i) the inaccuracy or breach of any representation or warranty made by the Buyer set forth in this Agreement or in any other agreement or any certificate delivered or provided in connection with or related to the consummation of the transactions contemplated by this Agreement; and (ii) the nonfulfillment of any covenant or agreement on the part of the Buyer set forth in this Agreement or in any agreement or certificate executed and delivered by the Buyer pursuant to this Agreement or in the transactions contemplated hereby.

9.2                                 Indemnification Procedures. In the event of the assertion or commencement by any Person of any claim or legal proceeding (whether against Buyer or against any other Person) with respect to which any Indemnified Party may be entitled to indemnification pursuant to this Article  IX, the Indemnified Party shall have the right, at its election, to proceed with the defense (including settlement or compromise) of such claim or legal proceeding on its own; provided, however, that if the Indemnified Party settles or compromises any such claim or legal proceeding without the consent of the Indemnifying Party, such settlement or compromise shall not be conclusive evidence of the amount of Damages incurred by the Indemnified Party in connection with such claim or legal proceeding (it being understood that if the Indemnified Party requests that the Indemnifying Party consent to a settlement or compromise, the Indemnifying Party shall act reasonably in determining whether to provide such consent). The Indemnified Party shall give the Indemnifying Party prompt notice after it becomes aware of the commencement of any such claim or legal proceeding against the Indemnified Party; provided, however, any failure on the part of Indemnified Party to so notify the Indemnifying Party shall not limit any of the obligations of the Indemnifying Party (or the Sellers), or any of the rights of any Indemnified Party, under this Article  IX (except to the extent such failure materially adversely prejudices the defense of such claim or legal proceeding). If the Indemnified Party does not elect to proceed with the defense (including settlement or compromise) of any such claim or legal proceeding, the Indemnifying Party may proceed with the defense of such claim or legal proceeding with counsel reasonably satisfactory to the Indemnified Party; provided, however, that the Indemnifying Party may not settle or compromise any such claim or legal proceeding without the prior written consent of the Indemnified Party (which consent may not be unreasonably withheld). No Buyer Indemnified Party (other than Buyer or any successor thereto or assign thereof) and no Seller Indemnified Party (other than the Seller Representative or any successor thereto or assign thereof) shall be permitted to assert any indemnification claim or exercise any other remedy under this Agreement unless, in the case of the Buyer Indemnified Parties, Buyer (or any successor thereto or assign thereof) or, in the case of the Seller Indemnified Parties, the Seller Representative (or successor thereto or assign thereof), shall have consented to the assertion of such indemnification claim or the exercise of such other remedy. Nothing herein shall be deemed to prevent the Indemnified Party from making a claim, and an Indemnified Party may make a claim hereunder, for potential or contingent claims or demands; provided that the notice of such claim sets forth the specific basis for any such potential or contingent claim or demand to the extent then reasonably feasible and the Indemnified Party has reasonable grounds to believe that such a claim or demand may be made.

9.3                                 Right of Offset. In the event that any Seller shall have an indemnification obligation for Damages to the Buyer or any Buyer Indemnified Party, the Buyer shall have the right (but not the obligation) to offset the amount of such Damages against any portion of the Purchase Price owed to such Seller, including without limitation, any portion of the Second Post-Closing

47

Payment. If the Seller Representative has contested any claim for Damages by any Buyer Indemnified Party in accordance herewith, the Buyer shall have the right (but not the obligation) to offset the amount of such Damages against any portion of the Purchase Price owed to such Seller, including without limitation, any portion of the Second Post-Closing Payment, until the Buyer receives (1) a written settlement agreement entered into by the Buyer and the Seller Representative, (2) an arbitration award issued in accordance with Section 12.9 hereof or (3) a final order or decision issued by a court of competent jurisdiction from which no appeal may be taken or for which the time to appeal has expired, as applicable, in any of which cases the Buyer will release the amount of such Damages offset pursuant hereto, if at all, in accordance therewith. No limitation on the Buyer’s ability to exercise the rights set forth in this Section shall affect such Buyer Indemnified Party’s rights hereunder or otherwise. Such remedy shall be in addition to and not in limitation of any injunctive relief or other rights or remedies to which the Buyer or any Buyer Indemnified Party is or may be entitled at law or equity or in any administrative or arbitration proceeding or under this Agreement (including any exhibits hereto).

9.4                                 Survival of Representations, Warranties and Covenants. Each covenant and agreement contained in this Agreement or in any agreement or other document delivered pursuant hereto shall survive the Closing and be enforceable until such covenant or agreement has been fully performed. All representations and warranties contained in this Agreement or in any agreement or other document delivered pursuant hereto shall survive the Closing until the date that is fifteen (15) months after the Closing Date and shall thereafter expire. The limitations on survivorship set forth in the preceding sentence of this Section 9.4 shall not apply to (i) the representations and warranties set forth in Sections 3.2 (Authority), 3.4 (Capitalization), 3.20 (Brokers), 4.3 (Company Shares), 4.4 (Brokers) and 5.7 (Brokers), all of which shall survive without limitation (and in no event less than six (6) years), (ii) claims based on criminal matters, fraud or intentional misrepresentation, which shall survive without limitation (and in no event less than six (6) years), (iii) the representations and warranties set forth in the Selected Government Contracts Sections, which shall survive for six (6) years after the Closing, or (iv) the representations and warranties set forth in Sections 3.8 (Employee Benefit Plans) and 3.10 (Taxes), which shall survive until the end of the applicable statute of limitations (or any extension thereof) plus ninety (90) days. Notwithstanding the foregoing, any representation or warranty with respect to which a claim has been made for a breach thereon prior to the end of the applicable survival period shall survive past the applicable survival period, if necessary, at least until such claim is resolved.

9.5                                 Limitations on Indemnification.

(a)                                  There shall be no liability for Damages for breaches of representations and warranties unless and until the aggregate amount of all Damages for all claims asserted by the Buyer Indemnified Parties exceeds Five Hundred Thousand Dollars ($500,000); provided, however, after such amount of Damages exceeds Five Hundred Thousand Dollars ($500,000), all Damages, excluding the first Two Hundred Fifty Thousand Dollars ($250,000), shall be recoverable by the Buyer Indemnified Parties. There shall be no liability for Damages for breaches of representations and warranties unless and until the aggregate amount of all Damages for all claims asserted by the Seller Indemnified Parties exceeds Five Hundred Thousand Dollars ($500,000); provided, however, after such amount of Damages exceeds Five Hundred Thousand Dollars ($500,000), all Damages, excluding the first Two Hundred Fifty Thousand Dollars

48

($250,000), shall be recoverable by the Seller Indemnified Parties. The limitations set forth in this Section 9.5(a) shall not apply to (i) the representations and warranties set forth in Section 3.2 (Authority), Section 3.4 (Capitalization), Section 3.8 (Employee Benefit Plans), Section 3.10 (Taxes), the Selected Government Contracts Sections, Section 3.20 (Brokers), Section 4.3 (Company Shares), Section 4.4 (Brokers) and Section 5.7 (Brokers), (ii) claims regarding Buyer’s obligation to pay the Second Per Share Post-Closing Amount or (iii) claims based on criminal matters, fraud or intentional misrepresentation, with respect to which, in each case, all Damages shall be recoverable from the first dollar and shall be counted in determining whether the thresholds in this Section 9.5(a) have been exceeded.

(b)                                 The indemnification obligations of the Sellers for breaches of representations and warranties shall be limited to an amount equal to Ten Million Dollars ($10,000,000). The indemnification obligations of the Buyer for breaches of representations and warranties shall be limited to an amount equal to Ten Million Dollars ($10,000,000). The foregoing limitations in this Section 9.5(b) above shall not apply to (i) the representations and warranties set forth in Section 3.2 (Authority), Section 3.4 (Capitalization), Section 3.8 (Employee Benefit Plans), Section 3.10 (Taxes), the Selected Government Contracts Sections, Section 3.20 (Brokers), Section 4.3 (Company Shares), Section 4.4 (Brokers) and Section 5.7 (Brokers), (ii) claims regarding Buyer’s obligation to pay the Second Per Share Post-Closing Amount or (iii) claims based on criminal matters, fraud or intentional misrepresentation, with respect to which, in each case, no Damages shall be counted in determining whether the cap in this Section 9.5(b) has been exceeded.

(c)                                  For purposes of determining any breach of any representation or warranty for purposes of indemnification under this Article IX, all representations and warranties shall be treated as if the words “materially,” “in all material respects” or similar words were omitted from such representations and warranties. The indemnification obligations of the parties hereto and the rights and remedies that may be exercised by an Indemnified Party shall not be limited or otherwise affected by or as a result of any information furnished to, or any investigation made by or knowledge of any of the Indemnified Parties or any of their Representatives.

(d)                                 The amount that may be recovered hereunder by an Indemnified Party shall be reduced by an amount equal to any insurance recovery actually received by the Indemnified Party (except to the extent of any repayment or increase in past, present or future insurance premiums or other similar repayment mechanisms payable following the date of the claim giving rise to such increase, determined on a present value basis) and shall be appropriately adjusted for calculations of the related Tax consequences and for the time value of money. The Buyer shall have the right to determine in its sole discretion whether to pursue any such insurance or Tax recovery.

9.6                                 Waiver, Release and Discharge. Effective upon the Closing, except as expressly set forth in this Agreement, each Seller hereby irrevocably waives, releases and discharges the Company, the Buyer and their respective Affiliates, directors, officers and employees, from any and all Liabilities and obligations to the Seller of any kind or nature whatsoever, whether in his or her capacity as a Seller hereunder, as a shareholder, officer, director or employee of the Company or otherwise (including, without limitation, in respect of rights of contribution or indemnification as a director or officer of the Company under Section 13.1 Chapter 9 of the

49

VSCA or under the Articles of Incorporation or Bylaws of the Company or otherwise), in each case whether absolute or contingent, liquidated or unliquidated, known or unknown, and whether arising hereunder or under any other agreement or understanding or otherwise at law or equity or in any administrative or arbitration proceeding, and each Seller shall not seek to recover any amounts in connection therewith or thereunder from the Company. Each Seller waives, and acknowledges and agrees that he or she shall not have and shall not exercise or assert (or attempt to exercise or assert), any right of contribution, right of indemnity or other similar right or remedy against the Company, the Buyer and their respective Affiliates, directors, officers and employees, in connection with any actual or alleged breach by the Company or any Seller of any representation, warranty or obligation set forth in this Agreement.

9.7                                 Exclusive Remedy. The provisions of this Article IX shall constitute the sole and exclusive remedy from and after the Closing with respect to any Damages suffered, sustained, incurred or paid by any Indemnified Party resulting from or arising out of any breach of any representation or warranty made in this Agreement or in any other agreement or any certificate delivered or provided pursuant hereto, except for specific performance and equitable remedies as set forth in Article X and Section 12.3 and except in the case of criminal matters, fraud or intentional misrepresentation.

ARTICLE X
COVENANT NOT TO COMPETE

10.1                           Prohibited Activities. For the period commencing with Closing and ending on the later of the third (3rd) anniversary of the Closing and two (2) years after the date of termination of any employment or consulting arrangement with the Buyer, the Company or the Buyer’s Affiliates, no Seller shall, for any reason whatsoever, directly or indirectly, for himself or herself, or on behalf of or in conjunction with any other Person:

(a)                                  engage as a stockholder, officer, director, owner, partner, joint venturer, or in a managerial capacity, whether as an employee, independent contractor, consultant or advisor, in any business selling any products or services in direct or indirect competition with the Buyer, the Company or the Buyer’s Affiliates; provided, however, that no Seller nor any of such Seller’s respective Affiliates shall be precluded from the ownership of securities of corporations that are listed on a national securities exchange or traded in the national over-the-counter market in an amount that shall not exceed one percent (1%) of the outstanding shares of any such corporation;

(b)                                 employ, or call upon for the purpose or with the intent of enticing or soliciting away from or out of the employ of the Buyer, the Company or any of the Buyer’s Affiliates, any person who is at that time, or was within one (1) year prior to that time, an employee of the Buyer, the Company or any of the Buyer’s Affiliates;

(c)                                  sell products or services to, or call upon for the purpose of soliciting or selling products or services to, any Person who is at that time, or has been within one (1) year prior to that time, a customer or prospective customer of the Buyer, the Company or any of the Buyer’s Affiliates; or

50

(d)                                 publish any statement or make any statement (under any circumstances reasonably likely to become public) critical of the Buyer, the Company or any of the Buyer’s Affiliates, or in any way adversely affecting or otherwise maligning the reputation of the Buyer, the Company or any of the Buyer’s Affiliates.

The parties intend that the covenants contained in this Section 10.1 shall be deemed to be a series of separate covenants, one for each county in each state of the United States and, except for geographic coverage, each such separate covenant shall be identified in terms to the covenant contained in this Section 10.1.

10.2                           Confidentiality.

(a)                                  Each Seller and each of their respective Affiliates, (i) shall treat and hold as confidential all information concerning this Agreement (except such information as is necessary to be disclosed to such Seller’s advisors who agree or who have fiduciary obligations to treat such information as confidential) and the business and affairs of the Buyer, the Company and the Buyer’s Affiliates that is not already generally available to the public (the “Confidential Information”), (ii) shall not disclose, transfer, transmit or use any of the Confidential Information except in connection with this Agreement or in connection with their employment duties to the Buyer or the Company as authorized by the Buyer or the Company and (iii) shall deliver promptly to the Buyer, at the request and option of the Buyer, all tangible embodiments (and all copies) of the Confidential Information which are in his or her possession or under his or her control. Each Seller hereby acknowledges that such Confidential Information constitutes proprietary and trade secret information of the Buyer or the Company, as the case may be.

(b)                                 In the event that any Seller is requested or required (by oral question or request for information or documents in any legal proceeding, interrogatory, subpoena, civil investigative demand, or similar process) to disclose any Confidential Information, such Seller shall notify the Buyer promptly of the request or requirement so that the Buyer may seek an appropriate protective order or waive compliance with the provisions of this Section 10.2. If, in the absence of a protective order or the receipt of a waiver hereunder, any Seller is, on the advice of counsel, compelled to disclose any Confidential Information to any tribunal or other Government official or agency, such Seller may disclose the Confidential Information to the tribunal; provided that such Seller shall use his or her best efforts to obtain, at the request and expense of the Buyer, an order or other assurance that confidential treatment shall be accorded to such portion of the Confidential Information required to be disclosed as the Buyer shall designate.

10.3                           Damages. Because of the difficulty of measuring economic losses to the Buyer and its Affiliates as a result of a breach of the foregoing covenants in this Article X, and because of the immediate and irreparable damage that could be caused to the Buyer and its Affiliates for which it would have no other adequate remedy, each Seller agrees that the foregoing covenant may be enforced by the Buyer in the event of breach by such Seller, in addition to, but not in lieu of, any other available remedies, by injunctions and restraining orders and other equitable remedies.

51

10.4                           Reasonable Restraint. It is agreed by the Parties that the foregoing covenants in this Article X impose a reasonable restraint on the applicable Seller in light of the activities and business of the Buyer and its Affiliates on the date of the execution of this Agreement and the current plans of the Buyer and its Affiliates; but it is also the intent of the Parties, that such covenants be construed and enforced in accordance with the changing activities and business of the Buyer, the Company and the Buyer’s Affiliates throughout the term of this covenant.

10.5                           Independent Covenant. All of the covenants in this Article X shall be construed as an agreement independent of any other provision in this Agreement, and the existence of any claim or cause of action of any Seller against the Buyer, whether predicated on this Agreement or otherwise, shall not constitute a defense to the enforcement by the Buyer of such covenants. It is understood by the Parties hereto that the covenants contained in this Article X are essential elements of this Agreement and that, but for the agreement of the Sellers to comply with such covenants, the Buyer would not have agreed to enter into this Agreement. Each Seller and the Buyer have independently consulted with their respective counsel and have been advised concerning the reasonableness and propriety of such covenants with specific regard to the nature of the business conducted by the Buyer. Each Seller hereby agrees that all covenants contained in this Article X are material, reasonable and valid and waive any requirement of the Buyer to post a bond to strictly enforce the terms hereof. The covenants in this Article X are severable and separate, and the unenforceability of any specific covenant shall not affect the provisions of any other covenant. Moreover, in the event any court of competent jurisdiction shall determine that the scope, time or territorial restrictions set forth are unreasonable, then it is the intention of the Parties that such restrictions be enforced to the fullest extent which the court deems reasonable, and the Agreement shall thereby be reformed. The covenants contained in Article X hereof shall not be affected by any breach of any other provision hereof by any Party hereto but shall have no effect if this Agreement is terminated pursuant to Article XI.

ARTICLE XI
TERMINATION

11.1                           Termination.

(a)                                  This Agreement may, by notice given on or prior to the Closing Date, in the manner hereinafter provided, be terminated and abandoned at any time prior to the Closing Date:

(i)                                     by the Seller Representative if there has been a material misrepresentation or a material default or breach by the Buyer with respect to its representations in this Agreement or in any ancillary document or the due and timely performance of any of the Buyer’s covenants and agreements contained in this Agreement or in any ancillary document, and such misrepresentation, default or breach shall not have been cured within five (5) days after receipt by the Buyer of notice specifying particularly such misrepresentation, default or breach;

ARTICLE XII
MISCELLANEOUS

12.1                           Successors and Assigns. This Agreement shall inure to the benefit of and be binding upon the Parties and their respective successors and assigns; provided, however, that neither the Company nor any of the Sellers may make any assignment of this Agreement or any interest herein without the prior written consent of the Buyer and, except in connection with the Credit Agreement Consent or otherwise to Wachovia Bank, National Association (or any assignor, successor or other Person who assumes the Buyer’s Senior Debt or replaces Wachovia Bank, National Association or provides indebtedness for borrowed money to the Buyer), Buyer

53

may not make any assignment of this Agreement or any interest herein without the prior written consent of the Seller Representative. Any such purported assignment without such prior written consent shall be void and of no force or effect.

12.2                           Governing Law. This Agreement shall in all respects be interpreted, construed and governed by and in accordance with the laws of the Commonwealth of Virginia, without regard to its conflicts or choice of laws principles.

12.3                           Specific Performance. Each Party acknowledges that the other Parties shall be irreparably harmed and that there shall be no adequate remedy at law for any violation by any of them of any of the covenants or agreements contained in this Agreement. It is accordingly agreed that, in addition to, but not in lieu of, any other remedies which may be available upon the breach of any such covenants or agreements, each Party shall have the right to obtain injunctive relief to restrain a breach or threatened breach of, or otherwise to obtain specific performance of, the other Parties’ covenants and agreements contained in this Agreement. All rights and remedies of the Parties under this Agreement shall be cumulative, and the exercise of one or more rights or remedies will not preclude the exercise of any other right or remedy available under this Agreement or applicable Law.

12.4                           Severability. Each section, subsection and lesser section of this Agreement constitutes a separate and distinct undertaking, covenant and/or provision hereof. In the event that any provision of this Agreement shall finally be determined to be unlawful, such provision shall be deemed severed from this Agreement, but every other provision of this Agreement shall remain in full force and effect; provided, however, if such unlawful clause is so material to the Party for whose benefit the clause was originally included so that such Party would not have entered into this Agreement without such unlawful clause, the severability of such clause shall be arbitrated pursuant to Section 12.9 hereof. The preceding sentence is in addition to and not in place of the severability provisions in Article X.

12.5                           Amendment. This Agreement may be amended, supplemented or modified only by execution of an instrument in writing signed by the Buyer, the Company and the Seller Representative.

12.6                           Waiver. Any Party hereto may to the extent permitted by applicable Law (i) extend the time for the performance of any of the obligations or other acts of the other Parties hereto, (ii) waive any inaccuracies in the representations and warranties of the other Parties hereto contained herein or in any document delivered pursuant hereto or (iii) waive compliance with any of the agreements of the other Parties hereto contained herein. No such extension or waiver shall be effective unless set forth in a written instrument duly executed by or on behalf of the Party extending the time of performance or waiving any such inaccuracy or non-compliance. No waiver by any Party of any term of this Agreement, in any one or more instances, shall be deemed to be or construed as a waiver of the same or any other term of this Agreement on any future occasion.

The Seller Representative may direct the Buyer to satisfy any of the Seller’s obligations under this Section 12.8 at the Closing, in which case the First Post-Closing Payment shall be reduced by a corresponding amount.

12.9                           Arbitration.

(a)                                  Except as set forth in Article X, Section 12.3 and Section 12.9(c) hereof, any dispute, difference, controversy or claim arising in connection with or related or incidental to, or question occurring under, this Agreement or the subject matter hereof shall be finally settled under the Commercial Arbitration Rules (the “Rules”) of the American Arbitration Association (“AAA”), unless otherwise agreed, by an arbitral tribunal composed of three (3) arbitrators, at least one (1) of whom shall be an attorney experienced in corporate transactions, appointed by agreement of the Buyer and the Seller Representative in accordance with said Rules. In the event Buyer and the Seller Representative fail to agree upon a panel of arbitrators from the first list of potential arbitrators proposed by the AAA, the AAA will submit a second list in accordance with such Rules. In the event Buyer and the Seller Representative shall have failed to agree upon a full panel of arbitrators from such second list, any remaining arbitrators to be selected shall be appointed by the AAA in accordance with such Rules. If at the time of the arbitration Buyer and the Seller Representative agree in writing to submit the dispute to a single arbitrator, such single arbitrator shall be appointed by agreement of Buyer and the Seller Representative in connection with the foregoing procedure or failing such agreement by the AAA in accordance with such Rules. All arbitrators shall be neutral arbitrators and subject to Rule 19 of the Rules.

(b)                                 The arbitrators shall not have the authority to add to, detract from, or modify any provision hereof nor to award punitive damages to any injured Party. A decision by a majority of the arbitrators shall be final, conclusive and binding. The arbitrators shall deliver a written and reasoned award with respect to the dispute to each of the parties, who shall promptly act in accordance therewith. Any arbitration proceeding shall be held in Alexandria, Virginia.

(c)                                  The Parties hereby exclude any right of appeal to any court on the merits of the dispute. The provisions of this Section 12.9 may be enforced in any court having jurisdiction over the award or any of the Parties or any of their respective assets, and judgment on the award (including without limitation equitable remedies) granted in any arbitration hereunder may be entered in any such court. Nothing contained in this Section 12.9 shall prevent any Party from seeking injunctive or other equitable relief from any court of competent jurisdiction, without the need to resort to arbitration.

(d)                                 In any arbitration hereunder, the holders of Company Common Stock and their respective successors shall be bound by any and all actions taken by the Seller

56

Representative on their behalf pursuant to Section 2.3. All communications or writings sent to the Seller Representative shall be deemed notice to all of the holders of Company Common Stock hereunder.

12.10                     Complete Agreement. This Agreement, those documents expressly referred to herein, including all exhibits and schedules hereto, and the other documents of even date herewith, together with the Confidentiality and Non-Disclosure Agreement, dated August 29, 2005, between the Company and Buyer (which shall automatically terminate at Closing and be of no further force or effect), embody the complete agreement and understanding among the Parties and supersede and preempt any prior understandings, agreements or representation by or among the Parties, written or oral, which may have related to the subject matter herein.

12.11                     Absence of Third Party Beneficiary Rights. No provision of this Agreement is intended, nor will be interpreted, to provide or create any third party beneficiary rights or any other rights of any kind in any client, customer, Affiliate, stockholder, employee or partner of any Party hereto or any other Person.

12.12                     Mutual Drafting. This Agreement is the mutual product of the Parties, and each provision hereof has been subject to the mutual consultation, negotiation and agreement of each of the Parties, and shall not be construed for or against any Party hereto.

12.14                     Gender. Unless the context clearly indicates otherwise, where appropriate the singular shall include the plural and the masculine shall include the feminine or neuter, and vice versa, to the extent necessary to give the terms defined herein and/or the terms otherwise used in this Agreement the proper meanings.

12.15                     Headings. The headings in this Agreement are intended solely for convenience of reference and shall be given no effect in the construction or interpretation of this Agreement.

12.16                     Counterparts.
