If the Closing Net Worth exceeds the Pro Forma Closing Net Worth, then the Closing Net Worth Adjustment shall be positive; and if the Closing Net Worth is less than the Pro Forma Closing Net Worth, then the Closing Net Worth Adjustment shall be negative. The Company shall estimate in good faith the Closing Net Worth, as of Closing, and deliver (i) such estimate, which shall include an unaudited balance sheet of the Company as of a date within three (3) Business Days prior to the Closing Date that (A) is prepared in accordance with GAAP, applied in a manner consistent with and using all of the same accounting principles, practices, methodologies and policies (which, in the case of judgments, shall be judgments consistent with the applicable judgments made with respect to the Company Balance Sheet) used in the preparation of the Company Balance Sheet (the “Accounting Principles”) and (B) reflects balance sheet account balances consistent with average balances of such accounts for September 2004 through March 2005 unless the Company and Buyer agree otherwise, and (ii) copies of the working papers used to prepare such estimate and unaudited balance sheet to Buyer, no later than three (3) Business Days before the Closing Date (the difference between such estimate and the Pro Forma Closing Net Worth, if any, being the “Estimated Net Worth Adjustment”).

The

- 20 -

Merger Parties acknowledge that (A) the sole purpose of the determination of Closing Net Worth is to adjust the Initial Purchase Price so as to reflect the change in net worth of the Company from the Pro Forma Closing Net Worth to the actual net worth of the Company on the Closing Date. For purposes of this Agreement, “Closing Net Worth” shall mean the Company’s assets as of the Closing, less the Company’s Liabilities as of Closing, both as reflected on the Closing Date Balance Sheet, increased by the aggregate amount of the items reducing the Initial Purchase Price as set forth in Sections 2.7(a) (i), (ii), (iii) and (v) and the amount of any corporate state Tax liability solely attributable to a deemed asset sale arising by reason of any Code Section 338(h)(10) election made by Buyer and the Shareholders, to the extent the amount of such items is accrued and included on the Closing Date Balance Sheet.

Section 2.10 Post-Closing Adjustment Payments.

(a) Buyer, based on the Closing Date Balance Sheet, shall provide to the Shareholder Representative, within sixty (60) days after Closing, (i) a copy of the Closing Date Balance Sheet accompanied by the unqualified report of Company’s accountant as provided in Section 2.9(b), and (ii) a copy of Buyer’s independent accountants’ calculation of (A) the actual Closing Net Worth Adjustment, if any (the “Actual Net Worth Adjustment”); (B) the amount by which, if any, Closing Net Worth exceeds the Pro Forma Closing Net Worth and, in such case, the amount if any, by which a positive Estimated Net Worth Adjustment is less than a positive Actual Net Worth Adjustment or the amount, if any, by which a negative Estimated Net Worth Adjustment is greater than a negative Actual Net Worth Adjustment or the spread, if any, between a negative Estimated Net Worth Adjustment and a positive Actual Net Worth Adjustment (in each such case, a “Shareholder Net Worth Adjustment”); and (C) the amount by which, if any, Pro Forma Closing Net Worth exceeds Closing Net Worth and, in such case, the amount, if any, by which a positive Estimated Net Worth Adjustment is greater than a positive Actual Net Worth Adjustment or the amount, if any, by which a negative Estimated Net Worth adjustment is less than a negative Actual Net Worth adjustment or the spread, if any, between a positive Estimated Net Worth Adjustment and a negative Actual Net Worth Adjustment (in each such case, a “Buyer Net Worth Adjustment”) (such materials in item (ii) of this Section 2.10(a), the “Purchase Price Adjustment Notice”).

(b) Buyer, at the Shareholder Representative’s request, shall allow the Shareholder Representative and his or her representatives reasonable access at all reasonable times to the Surviving Corporation’s and Company’s accountants, personnel, properties, Books

and Records, work papers, schedules and calculations directly relating to the Closing Date Balance Sheet, the Actual Net Worth Adjustment, Buyer Net Worth Adjustment, if any, and Shareholder Net Worth Adjustment, if any, for the purpose of reviewing the Purchase Price Adjustment Notice and the Closing Date Balance Sheet and confirming the accuracy of the preparation thereof. Any Buyer Net Worth Adjustment or Shareholder Net Worth Adjustment shall be paid within thirty (30) days of the Shareholder Representative’s receipt of the Purchase Price Adjustment Notice, except for any of the Buyer Net Worth Adjustment or the Shareholder Net Worth Adjustment, as the case may be, for which the Shareholder Representative has provided Buyer with a Shareholder Purchase Price Adjustment Objection Notice (as subsequently defined) in good faith. In the event that the Shareholder Representative provides such notice (“Shareholder Purchase Price Adjustment Objection Notice”) to Buyer no later than thirty (30) days after receipt of the Purchase Price Adjustment Notice that the Shareholders in good faith dispute Buyer’s independent accountants’ determination of the Actual Net Worth Adjustment, if any, the Buyer Net Worth Adjustment, if any, and/or the Shareholder Net Worth Adjustment, if any, determined in accordance with Section 2.10(a), the Shareholder Representative and Buyer shall then meet and negotiate in good faith to resolve such dispute, such negotiation to begin as soon as practicable (but in any case, no later than thirty (30) days) after Buyer’s receipt of the Shareholder Purchase Price Adjustment Objection Notice.

(c) In the event that Buyer and the Shareholder Representative are not able to resolve such dispute within thirty (30) days after the date on which Buyer receives the Shareholder Purchase Price Adjustment Objection Notice, then the Shareholder Representative and Buyer may refer the issues in dispute to a neutral, mutually acceptable independent accounting firm of national reputation with which no party hereto has had a preexisting relationship for resolution (the “Purchase Price Adjustment Referee”) and, immediately thereafter, shall provide notice of such referral to the other Merger Parties. If, within ten (10) days after the date on which Buyer received the Shareholder Purchase Price Adjustment Objection Notice, the parties are unable to agree on a neutral accounting firm to act as Purchase Price Adjustment Referee, (i) each party shall select a neutral accounting firm of national reputation and such firms together shall select the neutral accounting firm to act as the Purchase Price Adjustment Referee, and (ii) if any party does not select a neutral accounting firm within ten (10) days of written demand therefore by the other party, the independent neutral accounting firm selected by the other party shall act as the Purchase Price Adjustment Referee.

INDEMNIFICATION

Subject to Section 7.3, the Shareholders severally, pro rata in accordance with their Pro Rata Interests, shall indemnify, defend and hold Buyer, Merger Sub and Buyer’s Affiliates (collectively, the “Buyer Parties”) harmless from and against any and all Losses asserted against, imposed on, or incurred or suffered by Buyer, Merger Sub, the Company or the Surviving Corporation as a result of (a) the inaccuracy of any representation or the breach of any warranty set forth in Article III, any Company Disclosure Schedule delivered by the Company in connection with Article III or in any agreement or certificate executed and delivered by the Company or any Shareholder pursuant to this Agreement; (b) the non-fulfillment of any covenant or agreement on the part of the Company or any Shareholder set forth in this Agreement or in any agreement or certificate executed and delivered pursuant to this Agreement; or (c) any payments by or liabilities of Buyer arising in connection with payments to holders of Dissenting Shares, in excess of the portion of the Aggregate Merger Consideration otherwise payable to any such Shareholder in connection with this Agreement (collectively, “Indemnified Losses”). Each Shareholder irrevocably waives any and all rights to recourse against the

- 63 -

Company or the Surviving Corporation with respect to any misrepresentation or breach of any representation, warranty or indemnity, or noncompliance with any conditions, covenants or agreements, given or made by the Company in this Agreement. No Shareholder shall be entitled to contribution from, subrogation to or recovery against the Company or the Surviving Corporation with respect to any liability of such Shareholder that may arise under or pursuant to this Agreement or the transactions contemplated hereby.

Section 7.2 Indemnification by Buyer and Merger Sub.

Subject to Section 7.3, Buyer and Merger Sub shall, jointly and severally, indemnify, defend and hold the Shareholders harmless from and against any and all Losses asserted against, imposed on, or incurred or suffered by the Shareholders as a result of (a) the inaccuracy of any representation or the breach of any warranty set forth in Article IV, any Schedule delivered by Buyer and/or Merger Sub in connection with Article IV or in any agreement or certificate executed and delivered by Buyer or Merger Sub pursuant to this Agreement; or (b) the non-fulfillment of any material covenant or agreement on the part of Buyer or Merger Sub set forth in this Agreement or in any agreement or certificate executed and delivered pursuant to this Agreement.

Section 7.3 Survival of Representations and Warranties; Limitations on Indemnification.

(a) Survival. The representations and warranties in this Agreement and the indemnification provisions in this Agreement with respect thereto shall survive the Closing for a period of one (1) year following the Closing Date, at which time they shall terminate and no claim shall thereafter be brought in respect of them; provided, however, that such termination shall not affect any claim for breach of any representation or warranty if written notice thereof, in reasonable detail, has been given to the breaching party prior to such termination date (in such case, the survival period for the representation and warranty shall continue until the claim is fully resolved). The covenants of the parties set forth in this Agreement to be performed after the Closing shall survive until performed. Notwithstanding the foregoing to the contrary, the representations and warranties in Sections 3.1, 3.2(a), 3.2(c), 3.3, and 3.4 of this Agreement and the indemnification obligations of the Shareholders with respect thereto and with respect to any claims for fraud brought by the Buyer Parties against the Shareholders shall survive for the longer of (i) one (1) year following the Closing Date or (ii) expiration of the respective, applicable statute of limitations. Notwithstanding the foregoing to the contrary, the representations and warranties in Section 3.22 of this Agreement and the indemnification obligations of the Shareholders with respect thereto shall survive for three (3) years following the Closing Date.

(b) Limitations on Indemnification. Notwithstanding anything else in this Agreement to the contrary, Buyer Parties shall only be entitled to indemnification from the Shareholders pursuant to this Article VII if the amount of all Indemnified Losses incurred in the aggregate by the Buyer Parties exceeds Fifty Thousand dollars ($50,000) (the “Deductible”). If the aggregate amount of all Indemnified Losses incurred by the Buyer Parties exceeds in the aggregate the Deductible, the Buyer Parties shall be entitled to indemnification for all such Indemnified Losses in excess of the Deductible. Notwithstanding the foregoing, the obligation

- 64 -

and liability for any and all Indemnified Losses and any other indemnification obligations set forth in this Agreement by the Shareholders shall not exceed fifteen percent (15%) of the Adjusted Purchase Price (the “Indemnification Cap”) and, subject to Section 7.3(c) the aggregate amount to be paid by a Shareholder under this Article VII shall not exceed his or her Pro Rata Interest as set forth on the Certificate of Share Ownership of an amount equal to 15% of the Adjusted Purchase Price. Notwithstanding the foregoing to the contrary, neither the Deductible nor the Indemnification Cap shall apply to any claims for fraud or any claims for breach under Sections 3.1, 3.2(a), 3.2(c), 3.3, and 3.4, for which Buyer Parties’ rights to indemnification shall be unlimited. Notwithstanding the foregoing to the contrary the obligation and liability for any and all Indemnified Losses relating to the breach of Section 3.6(a) and/or Section 3.6(i) (and any other Tax-related representation, warranty, or covenant under this Agreement, to the extent that the circumstances giving rise to such breach also give rise to a breach of Section 3.6(a) or 3.6(i)) shall be considered separately from all other Indemnified Losses, and such amount shall not exceed Ten Million Dollars ($10,000,000) (the “Tax Indemnification Cap”). Any Losses from, and any indemnification or recovery relating to, the breach of such Section 3.6(a) and Section 3.6(i) (and any other Tax-related representation, warranty, or covenant under this Agreement, to the extent that the circumstances giving rise to such breach also give rise to a breach of Section 3.6(a) or 3.6(i)) shall be distinct from and considered separately from (and such Losses shall not be included in) the aggregate amount of all Indemnified Losses when giving effect to the provisions relating to the Indemnification Cap, and the aggregate amount to be paid by a Shareholder with respect thereto shall not exceed his or her Pro Rata Interest as set forth on the Certificate of Share Ownership of the Tax Indemnification Cap.

(c) Payment of Indemnification Obligations. Subject to the terms of this Article VII and the terms of the Escrow Agreement, prior to Buyer Parties proceeding against the Shareholders personally, any indemnification obligations of the Shareholders under this Agreement shall be paid and satisfied first from the Escrow Amount deposited with the Escrow Agent (with such payments being deducted from each Shareholder’s share of the Escrow Amount on a pro rata basis in accordance with their Pro Rata Interests) until the earlier of (i) such time as the Escrow Amount is exhausted or (ii) the release of the Escrow Amount as provided in the Escrow Agreement; provided, however, that with respect to a breach of the obligations described in Section 5.13(a)-(d), Buyer Parties shall first proceed against the Restricted Employee or Restricted Employees who breached the obligation, to fully recover the resulting Losses determined without regard to any Indemnification Cap or other limitation on liability set forth in Section 7.3(b), above, and only after proceeding against such Restricted Employee in a court of law through final judgment may, proceed against either the portion of the Escrow Amount attributable to the other Shareholders’ Pro Rata Interests or against the other Shareholders in satisfaction of the Losses subject to the Indemnification Cap and other limitations set forth in this Article VII.

(d) Insurance Proceeds. An indemnified party shall reimburse the Shareholder for amounts paid to the indemnified party by such Shareholder with respect to a Loss pursuant to the terms of this Agreement to the extent that such indemnified party receives any insurance proceeds with respect to such Loss.

- 65 -

(e) Mitigation. Each party agrees to take commercially reasonable steps to mitigate their respective Losses upon and after becoming aware of conditions giving rise to Losses that are indemnifiable hereunder.

(f) Subrogation. Upon making any payment to the indemnified party for an indemnification claim hereunder, the indemnitor shall be subrogated to the extent of such payment to any rights that the indemnified party may have against any third parties with respect to the subject matter underlying such indemnification claim.

(g) Third Party Claims. In calculating any Losses there shall be deducted any indemnification, contribution or other similar payment actually recovered by the indemnified party or any Affiliate thereof from any third Person with respect thereto so long as such recovered claim has been finally determined and is not subject to appeal.

(h) Tax Benefit. In calculating any Losses there shall be deducted therefrom the amount of any Tax benefit or Tax refund actually enjoyed or actually received by the applicable indemnified party or any Affiliate thereof as a result of such Losses provided, however, that such Tax benefit shall be calculated net of any Tax paid or payable in connection with any actual or reasonably anticipated recovery of all or some of such Losses.

(i) No Shareholder shall have liability to Buyer under any provision of this Agreement for any Losses to the extent that such Losses arise solely and directly from any intentional actions outside the ordinary course of business taken or omitted to be taken by Buyer or any of its Affiliates with respect to the Company after the Closing Date.

(j) Notwithstanding anything to the contrary in this Agreement:

(i) If the Shareholders may have an indemnification obligation under this Agreement with respect to a Loss arising out of or relating to environmental laws or hazardous substances (an “Environmental Loss”), the Shareholder Representative at its own expense shall have the right to enter into the facilities and to control, direct and implement any environmental investigation, monitoring, remediation, abatement, excavation or other response or removal action relating to such Environmental Loss.

(ii) To the extent that the Shareholders may have an indemnification obligation under this Agreement with respect to an Environmental Loss, Buyer shall not be entitled to claim or seek indemnity or defense under this Agreement with respect thereto to the extent that such Environmental Loss would not have arisen but for any intrusive investigation or disclosure by Buyer or any Affiliate thereof, unless such investigation or disclosure was required by applicable Environmental Laws.

(k) Indemnified Losses shall not include any special, exemplary or punitive damages, and neither the Shareholders nor the Buyer Parties shall be liable for any special, exemplary or punitive damages under this Agreement, except to the extent that such special, exemplary or punitive are asserted by a Third Party.

- 66 -

Section 7.4 Escrow Account.

(a) Deposit of Funds into Escrow Account. As security for the indemnity provided for in Section 7.1, at the Effective Time, Buyer shall deposit into the Escrow Account, on behalf of the Shareholders, the Escrow Amount, as contemplated by Section 2.7(c). In the event that the Shareholders shall owe an indemnification obligation to Buyer Parties, Buyer Parties shall be permitted to seek satisfaction of such obligation through an offset against the Escrow Amount. No limitation of such right of offset shall otherwise affect a Buyer Party’s rights hereunder or otherwise. The remedy of offset shall be in addition to and not in limitation of any injunctive relief or other rights or remedies to which Buyer Parties are or may be entitled, at law or equity, under this Agreement.

(b) Escrow Period; Final Distribution From the Escrow Account. Subject to the following requirements, the Escrow Account shall be in existence immediately following the Effective Time and shall terminate at 5:00 p.m., Washington, D.C. time, on the fifth (5^th) day following the Escrow Termination Date; provided that the Escrow Account shall not terminate on such date with respect to such remaining portion of the Escrow Amount (or some portion thereof) that in the reasonable judgment of Buyer, subject to the objection of the Shareholder Representative and the subsequent arbitration of the matter in the manner provided in Section 7.5, is necessary to satisfy (i) any then pending unsatisfied claims specified in any Officer’s Certificate delivered to the Escrow Agent by Buyer prior to the Escrow Termination Date, and (ii) any unsatisfied claims specified in any Officer’s Certificate delivered to the Escrow Agent by Buyer prior to the Escrow Termination Date with respect to facts and circumstances existing prior to the Escrow Termination Date. After the Escrow Termination Date and as soon as all such claims have been resolved, the Escrow Agent shall distribute funds from the Escrow Account sufficient to satisfy the expenses of the Shareholder Representative in connection with the Escrow Account and shall thereafter deliver to the Shareholders ratably in accordance with their respective Pro Rata Interests as set forth on the Certificate of Share Ownership hereto the remaining portion of the Escrow Account not required to satisfy such claims and expenses.

Section 7.5 Method of Asserting Claims.

All claims for indemnification by a party entitled to be indemnified hereunder shall be asserted and resolved as follows:

(a) Claims by Buyer Parties. In the event a Buyer Party has a claim for an Indemnified Loss against the Shareholders hereunder which does not involve a claim being asserted against or sought to be collected by a third party (a “Buyer Claim”), Buyer Parties shall promptly notify the Shareholder Representative in writing of such claim specifying the nature of the claim and the amount or the estimated amount thereof to the extent then feasible (which estimate shall not be conclusive of the final amount of such claim) (the “Claim Notice”). If the Shareholder Representative does not dispute all or any part the Buyer Claim in a written notice delivered to the Buyer within sixty (60) days of receipt of the Claim Notice, the Shareholder Representative shall be deemed to have accepted responsibility for the undisputed Buyer Claims set forth in such notice and shall have no further right to contest such undisputed Buyer Claims. Buyer may proceed to collect the undisputed amount of the Buyer Claim from the Escrow

- 67 -

Account as set forth in Sections 7.5(b) or 7.5(c), and then collect the undisputed amount of the Buyer Claim from the Shareholders. If the Shareholder Representative disputes any portion of a Buyer Claim in writing in accordance with this Section 7.5(a), the parties shall attempt to resolve such dispute in accordance with Section 7.5(d).

(b) Claims Upon Escrow Account. In accordance with the terms of the Escrow Agreement, upon receipt by the Escrow Agent at any time on or before the Escrow Termination Date of a certificate signed by any officer of Buyer (an “Officer’s Certificate”): (i) stating that Buyer has paid or properly accrued or reasonably anticipates that it will have to pay or accrue Indemnified Losses subject to indemnification by the Shareholders, and (ii) specifying in reasonable detail the individual items of Indemnified Losses included in the amount so stated, the date each such item was paid or properly accrued, or the basis for such anticipated liability, and the nature of the misrepresentations, breach of warranty or covenant to which such items are related, the Escrow Agent shall, subject to the provisions of Section 7.5(c), be directed to distribute to Buyer from the Escrow Account as promptly as practicable, funds in an amount equal to such Indemnified Losses.

(c) Objections to Claims. At the time of delivery of any Officer’s Certificate to the Escrow Agent, a duplicate copy of such certificate shall be delivered by Buyer to the Shareholder Representative and for a period of thirty (30) days after such delivery, the Escrow Agent shall make no distribution to Buyer of any funds contained in the Escrow Account pursuant to Section 7.5(b) unless the Escrow Agent shall have received written authorization from the Shareholder Representative to make such distribution. After the expiration of such thirty (30) day period, the Escrow Agent shall be directed to distribute funds from the Escrow Account in accordance with Section 7.5(b), provided that no such payment or delivery may be made if the Shareholder Representative shall object in a written statement to the claim made in the Officer’s Certificate, and such statement shall have been delivered to the Escrow Agent prior to the expiration of such thirty (30)-day period.

(d) Resolution of Conflicts; Arbitration.

(i) In case the Shareholder Representative shall so object in writing to any claim or claims made in any Officer’s Certificate or any Claim Notice, Buyer shall have ten (10) days to respond in a written statement to the objection of the Shareholder Representative. If after such ten (10)-day period, there remains a dispute as to any such claim, the parties shall attempt in good faith for thirty (30) days to agree upon the rights of the respective parties with respect to each of such claims. If the Shareholder Representative and Buyer should so agree, a memorandum setting forth such agreement shall be prepared and signed by the Shareholder Representative and Buyer, and shall be furnished to the Escrow Agent. In the event that the Buyer Parties have elected to offset any such claim against the Escrow Amount pursuant to an Officer’s Certificate, the Escrow Agent shall be entitled to rely on any such memorandum and distribute funds from the Escrow Account in accordance with the terms thereof.

- 68 -

(ii) If no such agreement can be reached after good faith negotiation, either Buyer, on the one hand, or the Shareholder Representative, on the other, may demand arbitration of the matter unless the amount of the damage or loss is at issue in pending litigation with a third party, in which event arbitration shall not be commenced until such amount is ascertained or both parties agree to arbitration; and in either such event the matter shall be settled by arbitration conducted by one arbitrator mutually agreeable to Buyer and the Shareholder Representative. In the event that within forty-five (45) days after submission of any dispute to arbitration, Buyer and the Shareholder Representative cannot mutually agree on one arbitrator, Buyer and the Shareholder Representative shall each select one arbitrator, and the two arbitrators so selected shall select a third arbitrator to handle the dispute. Except as otherwise provided herein, the arbitration will be governed by Virginia procedural law as if the matter had been brought in a Circuit Court of the State of Virginia; provided, however, that (i) the parties waive any right to jury; (ii) there shall be no interlocutory appellate relief (such as writs) available; and (iii) discovery will be limited to matters which are directly relevant to the issues in the arbitration; provided, however, that in any case where the damage or loss at issue includes any claim for Losses in the nature of consequential damages (including lost profit) all three arbitrators so chosen shall handle the dispute. The arbitrator(s) shall rule upon motions to compel or limit discovery and shall have the authority to impose sanctions, including attorneys’ fees and costs, to the extent as a court of competent law or equity, should the arbitrator(s) determine that discovery was sought without substantial justification or that discovery was refused or objected to without substantial justification. To appeal the judgment of the arbitrator, a party must follow all of the prerequisites for appealing a judgment of the Circuit Court, directing all such prerequisites to the American Arbitration Association (the “Arbitration Administrator”) in lieu of the clerk. All appeals will be made to 3 neutral arbitrators (“Appellate Arbitrators”) selected in accordance with the procedures set forth above. The Appellate Arbitrators will conduct a hearing, review the judgment of the arbitrator, and issue an appellate decision applying the same standards of review (and all of the same presumptions) as if the Appellate Arbitrators were judges of the Virginia Court of Appeal reviewing a judgment of the Circuit Court. The Appellate Arbitrators will be vested with the same powers as a Virginia Court of Appeal (including the power to remand a matter to an arbitrator). The decision of the Appellate Arbitrators as to the validity and amount of any claim in such Officer’s Certificate or Claim Notice shall be binding and conclusive upon the parties to this Agreement (unless remanded to

- 69 -

the arbitrator). In the event that the Buyer Parties have elected to offset any such claim against the Escrow Amount, notwithstanding anything in Section 7.5(b) or (c) to the contrary, Buyer and Shareholder Representative shall direct the Escrow Agent to act in accordance with such decision and make or withhold payments out of the Escrow Account in accordance therewith. The decision of the arbitrator(s) shall be written and shall be supported by written findings of fact and conclusions which shall set forth the award, judgment, decree or order awarded by the arbitrator(s).

(iii) Judgment upon any award rendered by the Appellate Arbitrators may be entered in any court having jurisdiction. Any such arbitration shall be held in Fairfax, Virginia under the rules then in effect of the American Arbitration Association. The arbitrator shall determine how all expenses relating to the arbitration shall be paid, including the respective expenses of each party, the fees of each arbitrator and the administrative fee of the American Arbitration Association.

(e) Third-Party Claims. In the event Buyer becomes aware of a third-party claim which Buyer believes may result in a demand against the Shareholders (or the Escrow Amount) (a “Third–Party Claim”), Buyer shall promptly provide a Claim Notice to the Shareholder Representative with respect to such Third–Party Claim. The Shareholder Representative, on behalf of the Shareholders, at the Shareholders’ sole cost and expense has the right, exercisable by written notice to Buyer within thirty (30) days after receipt of a Claim Notice from Buyer with respect to a Third-Party Claim, to be represented by counsel of its choice and reasonably acceptable to Buyer and to assume, control, defend against, negotiate and otherwise deal with any proceeding, claim, or demand which relates to any Indemnified Loss with respect to such Thirty-Party Claim in accordance with the limits set forth in this Agreement; provided, however, that the (i) defense of such Third-Party Claim by the Shareholder Representative is not reasonably likely to have a Material Adverse Effect on Buyer; (ii) the Thirty-Party Claim solely seeks (and continues to seek) monetary damages; and (iii) Shareholder Representative expressly agrees in writing that as between the Shareholders and Buyer, the Shareholders may only satisfy and discharge the Third-Party Claim in accordance with the limits set forth in this Agreement (the “Litigation Conditions”). Buyer may participate in the defense of any Third-Party Claim which the Shareholder Representative is defending as provided in this Section 7.5(e) with counsel of Buyer’s choice and at its expense. If the Shareholder Representative does not assume the defense of a Third-Party Claim in accordance with this Section 7.5(e), Buyer shall have the right to control such defense. If the Shareholder Representative has assumed the defense of a Thirty-Party Claim as provided in this Section 7.5(e), the Shareholders will not be liable for any legal expenses subsequently incurred by Buyer in connection with the defense of the Thirty-Party Claim; provided, however, that if (i) any of the Litigation Conditions ceases to be met or (ii) the Shareholder Representative fails to take reasonable steps necessary to defend diligently such Third-Party Claim or abandons the defense of such Third-Party Claim, Buyer may assume its own defense and the Shareholders will be liable for all reasonable costs or expenses paid or incurred in connection with such defense. The party controlling the defense of such Third-Party Claim shall keep the other party advised of the

status of such Third-Party Claim and the defense thereof and shall consider in good faith the recommendations made by the other party with respect thereto. Neither Buyer nor the Shareholder Representative shall have the right to settle any Third-Party Claim without the consent of the other, which consent shall not be unreasonably withheld or delayed; provided, however, that the consent of the Buyer shall not be required if (i) any amounts payable pursuant to such settlement or compromise do not exceed the Escrow Amount, (ii) such settlement includes a complete written release of the Buyer from all liability with respect to such Third-Party Claim and does not impose any injunctive or equitable relief or other operational restrictions on the Buyer, and (iii) is not reasonably expected to have an adverse effect on the affected business of Buyer or its Affiliates; and, in case of any such settlement, the Shareholder Representative shall execute and deliver a memorandum to the Escrow Agent indicating the amount of such settlement, which memorandum may be relied upon by the Escrow Agent to offset the amount of such settlement against the Escrow Account. Except to the extent provided in the preceding sentence, no settlement of any such Third-Party Claim shall be determinative of the amount of any claim against the Shareholders or the Escrow Account. The parties agree to cooperate fully with each other in connection with the defense, negotiation or settlement of any such legal proceeding, claim or demand. In the event that the Shareholder Representative has consented to settlement of a Third-Party Claim pursuant to the provisions of this Section 7.5(e), neither the Shareholder Representative or the Shareholders shall have the power or authority to object to the amount of any claim by Buyer against the Escrow Account or the Shareholders in the amount of such settlement.

(f) Claims by Shareholders. In the event that the Shareholders have a claim against a Buyer Party hereunder, the Shareholder Representative shall promptly notify Buyer in writing of such claim specifying the nature of such claim and the amount or the estimated amount thereof to the extent then feasible (which estimate shall not be conclusive of the final amount of such claim). If the Buyer does not notify the Shareholder Representative within sixty (60) days of receipt of such notice that Buyer Parties dispute such claim, the amount of such claim shall be conclusively deemed a liability of the Buyer Parties hereunder. In case an objection is made in writing in accordance with this Section 7.5(f), the Shareholder Representative shall have ten (10) days to respond in a written statement to the objection of the Buyer Parties. If after such ten (10)-day period there remains a dispute as to any claim, the parties shall attempt in good faith for thirty (30) days to agree upon the rights of the respective parties with respect to each of such claims. If the parties should so agree, a memorandum setting forth such agreement shall be prepared and signed by Buyer and Shareholder Representative. If no such agreement can be reached after good faith negotiation, the parties may demand an arbitrator to settle such dispute in the same manner set forth in Section 7.5(d)(ii) above.

Section 7.6 Remedies.

Except as otherwise set forth in this Agreement, this Article VII sets forth the sole exclusive remedy and recourse of the parties for monetary damages arising from any claim, cause of action or right of any nature under this Agreement; provided, however, that nothing contained in this Article VII shall be in lieu of, or constitute a waiver of, any nonmonetary equitable remedies for injunctive relief, specific performance or rescission that any party may otherwise have.

ARTICLE VIII

TAX MATTERS

Section 8.1 Tax Returns.

(a) Tax Periods Ending On or Before the Closing Date. The Shareholder Representative shall prepare or cause to be prepared and timely file or cause to be filed all state and federal income or franchise Tax Returns for the Company for taxable periods ending on or before the Closing Date which are filed after the Closing Date (the “Short Period Returns”). The Short Period Returns shall be prepared and filed in accordance with historic practices and procedures of the Company and applicable law, based on a closing of the books of Company as of immediately before the Closing. The Shareholder Representative shall direct the Escrow Agent to pay to the Surviving Corporation from funds comprising the Escrow Amount an amount equal to the portion of Company Taxes reported on such Tax Returns that relate to the portion of such taxable period ending on or before the Closing Date that were not paid before the Closing Date or that were not reserved for on the Closing Date Balance Sheet (rather than any reserve for deferred Taxes established to reflect timing differences between book and Tax income), except to the extent that such Taxes are allowable and recoverable costs for inclusion in the costs of agreements with Governmental Entities. Prior to filing any Short Period Return, the Shareholder Representative shall afford the Buyer a reasonable opportunity to review the proposed form of any Short Period Return and comment thereon.

(b) Tax Periods Beginning Before and Ending After the Closing Date. Buyer and the Surviving Corporation shall file or cause to be filed any Tax Returns of the Company for tax periods that begin before the Closing Date and end after the Closing Date (a “Straddle Period” and such Tax Returns, a “Straddle Period Return”) and pay all Taxes owed by the Company for such periods. Prior to Filing any Straddle Period Return, Buyer and the Surviving Corporation shall afford the Shareholder Representative a reasonable opportunity to review and comment on the proposed form of any Straddle Period Return. The Shareholder Representative shall direct the Escrow Agent to pay to the Surviving Corporation from funds comprising the Escrow Amount within fifteen (15) days after the date on which such Taxes are paid with respect to such periods an amount equal to the portion of such Company Taxes that relate to the portion of such taxable period ending on the Closing Date that were not paid before the Closing Date or that were not reserved for on the Closing Date Balance Sheet, except to the extent that such Taxes are allowable and recoverable costs for inclusion in the costs of agreements with Governmental Entities. For purposes of this Section 8.1(b), in the case of any Taxes that are payable by the Company for any Straddle Period, the portion of such Tax payable by the Company which relates to the portion of such taxable period ending on the day before the Closing Date shall (i) in the case of any Taxes other than Taxes based upon or related to income or receipts, be deemed to be the amount of such Tax for the entire taxable period multiplied by a fraction the numerator of which is the number of days in the taxable period ending on the day before the Closing Date and the denominator of which is the number of days in the entire taxable period, and (ii) in the case of any Tax based upon or related to income or receipts be equal to the amount which would be payable by the Company if the relevant taxable period ended on the day before the Closing Date (which shall include amount of any Tax solely attributable to a deemed asset sale arising by reason of any Code Section 338(h)(10) election made by Buyer and the

- 72 -

Shareholders). All determinations necessary to give effect to the foregoing allocations shall be made in a manner consistent with prior practice of the Company (taking into account (i) the Tax status of the Company for such period, including its Subchapter S corporation status for federal income tax purposes and any similar status for other Tax purposes, and (ii) Taxes that are allowable costs and recoverable for inclusion in the costs of agreements with Governmental Entities).

(c) Notwithstanding the foregoing provisions of Sections 8.1(a) and 8.1(b), Buyer shall pay, when due, to the relevant state Tax authorities on behalf of the Company the amount of any state income or franchise Taxes as shown on any Short Period Return or Straddle Period Return solely attributable to a deemed asset sale arising by reason of any Code Section 338(h)(10) election made by Buyer and the Shareholders up to an aggregate maximum of five hundred thousand dollars ($500,000). To the extent that the aggregate amount of state income or franchise Taxes as shown on any Short Period Return or Straddle Period Return solely attributable to a deemed asset sale arising by reason of any Code Section 338(h)(10) election made by Buyer and the Shareholders exceed five hundred thousand dollars ($500,000), then the Shareholder Representative, in its sole discretion, shall determine the amount and jurisdictions to which its payments shall be made.

Section 8.2 Certain Contest Rights.

(a) Promptly after receipt by Buyer, the Company or any Shareholder of a written notice of any demand, claim or circumstance that, either at such time or after the lapse of time, might give rise to an adjustment or audit of any Tax Return of the Company for periods ending on or prior to the Closing Date (“Shareholder Returns”), or Straddle Period Returns, the party receiving such notice shall notify the other parties hereunder (the “Tax Claim Notice”). The Tax Claim Notice shall contain factual information (to the extent known to the party receiving the inquiry or notice from the taxing authority) describing such demand, claim or circumstance, including any asserted tax liability (an “Asserted Tax Claim”) in reasonable detail and shall include copies of any notice or other document received in respect of any such Asserted Tax Claim.

(b) Subject to Buyer’s right to participate in any tax proceeding as described below, the Shareholder Representative, at its own cost and expense, shall have the power and authority (i) to control the conduct of the Company in respect of any Asserted Tax Claim to the extent it relates to any Shareholder Return, any Taxes with respect to which the Shareholders have an obligation to indemnify the Buyer pursuant to Article VII (the costs of any such audit or examination shall be borne by the Surviving Corporation up to $50,000 (so long as Buyer is permitted to fully participate in such proceedings) until the issuance of a notice of deficiency; the costs of any such audit or examination in excess of $50,000 and the costs of any administrative appeal or litigation after the issuance of a notice of deficiency shall be borne by Shareholders), (ii) to determine whether and to what extent to amend any Shareholder Return (including any Short Period Return), and (iii) whether and to what extent the Company shall extend or waive any statute of limitations for the assessment of any Tax with respect to any Shareholder Return. Buyer shall have the right to participate in any Asserted Tax Claim proceedings such tax audit, examination, appeal or litigation (collectively, a Asserted Tax Claim Proceeding”) at Buyer’s sole expense, and, notwithstanding the immediately preceding sentence, to jointly control with

- 73 -

the Shareholder Representative any such tax proceeding if the amount claimed by the taxing authority in a notice of deficiency would result in a liability to the Company that exceeds the Escrow Amount or, if the resolution of the matter at issue in such tax proceeding could materially adversely affect the Surviving Corporation with respect to any period after the Closing. In no event shall the Shareholder Representative settle any such tax proceeding without Buyer’s consent if such settlement would materially adversely affect the Company with respect to any period after the Closing or result in any material liability on the part of the Company or such successor in interest for which the Shareholder Parties are not obligated to indemnify the Buyer pursuant to Article VII or Article VIII of this Agreement. If Buyer withholds its consent to any proposed settlement to any Asserted Tax Claim (a “Proposed Settlement”), then each such Shareholder’s liability with respect to the subject matter of the Proposed Settlement shall be limited to the amount that such liability would have been if the Proposed Settlement had been accepted and the Buyer shall be responsible for all expenses incurred thereafter in connection with the contest of such tax audit or proceeding except to the extent that the final settlement imposes less liability on such Shareholder than the Proposed Settlement would have imposed (taking into account such Shareholder’s share of such expenses).

(c) Subject to the Shareholder Representative’s right to participate in any tax proceeding as described below, the Buyer, at its own cost and expense, shall have the power and authority (i) to control the conduct of the Company in respect of any Asserted Tax Claim to the extent it relates to any Straddle Period Return., (ii) to determine whether and to what extent to amend any Straddle Period Return, and (iii) whether and to what extent the Company shall extend or waive any statute of limitations for the assessment of any Tax with respect to any Straddle Period Return. The Shareholder Representative shall have the right to participate in any Asserted Tax Claim Proceedings at its sole expense, and, notwithstanding the immediately preceding sentence, to jointly control with the Buyer any such tax proceeding if the amount claimed by the taxing authority in a notice of deficiency could materially adversely effect the Shareholders. In no event shall the Buyer settle any such tax proceeding without the Shareholder Representative’s consent if such settlement would materially adversely affect the Shareholders. If the Shareholders Representative withholds its consent to any Proposed Settlement, then the Shareholders shall indemnify the Buyer for all expenses incurred thereafter in connection with such Asserted Tax Claim Proceeding except to the extent that the final settlement imposes less liability on the Company than the Proposed Settlement would have imposed (taking into account Buyer’s share of such expenses).

Section 8.3 Cooperation and Exchange of Information.

Each party hereto will provide each other with such cooperation and information as any of them may reasonably request of the other in filing any Tax Return of the Company, amended return or claim for refund, determining a liability for Taxes of the Company or a right to a refund of Taxes of the Company or in conducting any audit or other proceeding in respect of Taxes of the Company. Such cooperation and information shall include providing copies of relevant Tax Returns of the Company or portions thereof, together with accompanying schedules and related work papers and documents that are reasonably relevant to rulings or other determinations by taxing authorities. Each party shall make its representatives available on a mutually convenient basis to provide explanation of any documents or information provided hereunder. The Company, its Shareholders, Buyer and the Surviving Corporation agree (A) to retain all Books

- 74 -

and Records with respect to Tax matters pertinent to the Company relating to any taxable period beginning before the Closing Date until expiration of the statute of limitations (and, to the extent notified by Buyer or the Shareholders, any extensions thereof) of the respective taxable periods, and to abide by all record retention agreements entered into with any taxing authority, and (B) Buyer and the Surviving Corporation shall give the Shareholder Representative reasonable written notice prior to transferring, destroying or discarding any Books and Records with respect to Tax matters pertinent to the Company relating to any taxable period beginning before or on the Closing Date and, if the Shareholder Representative so requests, Buyer and the Surviving Corporation shall allow the Shareholder Representative to take possession of such Books and Records.

Section 8.4 Refunds.

In the event that the Shareholders receive a refund or credit of Tax of the Company for which the Buyer or the Company made a payment pursuant to Section 8.2 or any other provision of this Agreement, then the Shareholders shall promptly pay to the Buyer or the Company, as the case may be, the amount of such refund (including any accrued interest paid in respect of such refunded Tax) or credit to the extent the refund or credit represents payments made by or for the Buyer or the Surviving Corporation with respect to events occurring after the Closing Date. Each of Buyer and the Surviving Corporation shall agree jointly and severally that, as a condition to receiving any such refund or credit, in the event that any refund or credit of Taxes for which a payment has been made to Buyer or the Surviving Corporation pursuant to this Section 8.4 is subsequently reduced or disallowed, to indemnify and hold harmless the payor for any Tax liability assessed against such payor by reason of the reduction or disallowance.

SHAREHOLDER REPRESENTATIVE AND ESCROW AGENT

Section 10.1 The Shareholders and the Shareholder Representative.

(a) Any provision in this Agreement that grants rights or remedies to the Shareholders shall be deemed to be for the joint and several benefit of the Shareholders, unless otherwise specifically provided. Notwithstanding the foregoing, Buyer, Merger Sub and the Surviving Corporation shall be entitled to conclusively rely as to any obligation they may have hereunder to the Shareholders upon any written instruction, waiver, notice, request, demand or other communication delivered by or on behalf of the Shareholders by the Shareholder Representative.

(b) The Shareholder Representative shall have full power and authority to make all decisions on behalf of the Shareholders relating to the transactions contemplated by this Agreement. All decisions and actions by the Shareholder Representative relating to this Agreement and the transactions contemplated hereby shall be binding upon all Shareholders and no Shareholder shall have the right to object, dissent, protest or otherwise contest the same. In furtherance and not in limitation of the foregoing, as a material inducement to Buyer to enter into this transaction, the Shareholder Representative is irrevocably constituted and appointed as the true and lawful agent and attorney-in-fact of each Shareholder with full powers of substitution to act in the name, place and stead of each Shareholder in connection with the transactions contemplated in this Agreement such appointment to be a power coupled with an interest which shall survive the death or incapacity of any Shareholder. Each Shareholder irrevocably authorizes Buyer and Merger Sub to rely on all acts and communications taken or made by the Shareholder Representative on behalf of the Shareholders or any of them pursuant to or in connection with this Agreement, the related agreements and the transactions contemplated hereby and thereby.

- 77 -

(c) Notwithstanding anything to the contrary contained in this Agreement, the Shareholder Representative shall have no duties or responsibilities except those expressly set forth herein and in the Shareholder Release Agreements, and no implied covenants, functions, responsibilities, duties, obligations or liabilities on behalf of the Company or any Shareholder shall otherwise exist against the Shareholder Representative. Except as expressly provided in this Agreement, the Shareholder Representative shall have no duties or responsibilities to Buyer or its Affiliates.

(d) The Shareholder Representative shall promptly deliver to each Shareholder any notice received by the Shareholder Representative concerning this Agreement.

(e) Neither the Shareholder Representative nor any agent employed by the Shareholder Representative shall be liable to any Shareholder relating to the performance of such Shareholder Representative’s duties under this Agreement for any errors in judgment, negligence, oversight, breach of duty or otherwise except to the extent it is finally determined in a court of competent jurisdiction by clear and convincing evidence that the actions taken or not taken by the Shareholder Representative constituted fraud or were taken or not taken in bad faith. The Shareholder Representative shall be indemnified and held harmless by the Shareholders against all losses, including costs of defense, paid or incurred in connection with any action, suit, proceeding or claim to which the Shareholder Representative is made a party by reason of the fact that the Shareholder Representative was acting as the Shareholder Representative pursuant to this Agreement; provided, however, that the Shareholder Representative shall not be entitled to indemnification hereunder to the extent it is finally determined in a court of competent jurisdiction by clear and convincing evidence that the actions taken or not taken by the Shareholder Representative constituted actual fraud or were taken or not taken in bad faith. The Shareholder Representative shall be protected in acting upon any notice, statement or certificate believed by the Shareholder Representative to be genuine and to have been furnished by the appropriate Person and in acting or refusing to act in good faith on any matter. Neither the Shareholder Representative nor any agent employed by the Shareholder Representative shall be liable to the Buyer or any Affiliate of the Buyer by reason of this Agreement or the performance of Shareholder Representative’s duties hereunder or otherwise.

(f) For purposes of this Agreement, the initial Shareholder Representative shall be Xxxxx X. Xxxxxx. In the event of the resignation, death or incapacity of Xxxxx X. Xxxxxx, the duties of the Shareholder Representative shall be performed by a three (3) person committee consisting of Xxxxxxxx X. Xxxxxxx, Xxxxxx Xxxxx and Xxxxxx X. Xxxxx (“Shareholders’ Committee”). In the event that any individual authorized hereunder as a Shareholders’ Committee member shall die, become incapacitated, resign or otherwise fail to act on behalf of the Shareholders for any reason, a new individual shall be appointed to the committee by action or written consent of Shareholders who held immediately prior to the Closing Date no less than fifty-one percent (51%) of the Company Common Stock (other than shares held in the Company’s treasury), and if none is so selected within thirty (30) days, then the Shareholders’ Committee shall be reduced by one member. The unanimous vote of the Shareholders’ Committee members shall constitute the act of the Shareholders’ Committee. Upon formation, the Shareholders’ Committee shall designate one member as the notice recipient and furnish such member’s contact information to Buyer. Thereafter, in each case under this Agreement whereby Buyer is required to notify, contact or otherwise provide

- 78 -

information or documents to the Shareholder Representative, such requirement shall be satisfied by Buyer’s notification, contact or provision of information or documents to the designated Shareholders’ Committee member. Notwithstanding the formation of the Shareholders’ Committee, nothing in this Section 10.1(f) shall allow any extension or delay in the period of time that the Shareholders’ Representative is required to respond or otherwise act as set forth in this Agreement.

Section 10.2 Escrow Agent and Agreement.

(a) The Shareholders, the Company, Buyer and Merger Sub hereby agree that the Escrow Agent shall serve as an escrow agent to receive, hold, administer, and deliver the Escrow Funds and the proceeds thereunder in accordance with the Escrow Agreement. Any interest accruing on, and other earnings on investment of, the Escrow Funds shall be deemed to be a part of the Escrow Funds. The Shareholders shall include all amounts earned on the Escrow Funds in their gross incomes for federal, state and local income tax purposes and pay any income tax imposed thereon. Any loss or expense incurred as a result of an investment will be borne by the Escrow Funds. The parties recognize and agree that the Escrow Agent will not provide supervision, recommendations or advice relating to either the investment of the Escrow Funds or the purchase, sale, retention or other disposition of any investment. The Escrow Agreement will direct the Escrow Agent to send statements to each of the Buyer and the Shareholder Representative on a monthly basis reflecting activity in the Escrow Account for the preceding month.

(b) All fees of the Escrow Agent for performance of its duties shall be paid by Buyer in accordance with the standard fee schedule of the Escrow Agent. In the event that the conditions of this Agreement are not promptly fulfilled, or if the Escrow Agent renders any service not contemplated by this Agreement, or if the parties request a substantial modification of the terms of the Escrow Agreement, or if any controversy arises, or if the Escrow Agent is made a party to, or intervenes in, any litigation pertaining to the Escrow Fund or its subject matter, the Escrow Agent shall be reasonably compensated for such extraordinary services and reimbursed for all costs, attorneys’ fees, including allocated costs of in-house counsel, and occasioned by such default, delay, controversy or litigation (“Special Escrow Agent Costs”). Buyer promises to pay these sums upon demand. Notwithstanding anything to the contrary stated herein, the Shareholders, and not the Buyer, shall be responsible for all Special Escrow Agent Costs that are incurred by the Escrow Agent as a result of a situation or dispute in which it is determined that the Shareholders were chiefly at fault.

Upon and after the Closing, the Company shall cease to have any attorney-client relationship with SMRH, unless SMRH is specifically engaged in writing by the Company to represent the Company after Closing and either such engagement involves no conflict of interest with respect to Shareholders, the Shareholder Parties or the Shareholder Representative or the Shareholders, the Shareholder Parties or the Shareholder Representative (as applicable) consent in writing at the time to such engagement. Any such representation of the Company by SMRH after Closing shall not affect the foregoing provisions hereof. For example, and not by way of limitation, even if SMRH is representing the Company after the Closing, SMRH shall be permitted simultaneously to represent the Shareholders, the Shareholder Parties and/or the Shareholder Representative in any matter, including any disagreement or dispute relating thereto. Furthermore, SMRH shall be permitted to withdraw from any representation of the Company in order to be able to represent or continue so representing the Shareholders, the Shareholder Parties or the Shareholder Representative, even if such withdrawal causes the Company or Buyer additional legal expense (such as to bring new counsel “up to speed”), delay or other prejudice.
