1.6 Adjustment Before and After the Closing. The Initial Purchase Price shall be subject to adjustment as follows:

(a) Not later than three (3) business days prior to the Closing Date, the Company shall prepare and deliver to the Buyer a balance sheet of the Company (the “Preliminary Closing Balance Sheet”) as of the end of the month immediately preceding the Closing Date (the “Preliminary Closing Balance Sheet Date”). The Preliminary Closing Balance Sheet shall be prepared in accordance with the provisions relating to the preparation of the Closing Balance Sheet set forth in this Section 1.6. The Preliminary Closing Balance Sheet shall be accompanied by (i) all relevant backup materials and schedules, in detail reasonably acceptable to the Buyer, and (ii) a statement setting forth the amount, if any, by which the estimated Closing Working Capital (the “Preliminary Closing Working Capital”) is less than or greater than the Target Amount.

(b) Not later than 45 calendar days after the Closing Date, the Buyer shall deliver to the Seller the Closing Balance Sheet. Notwithstanding any requirement of GAAP to the contrary, the Closing Balance Sheet shall include all of the line items included on the illustrative balance sheet as of January 31, 2010 set forth on Schedule 1.6 attached hereto, which, for the avoidance of doubt, shall include accruals for all severance Liabilities and retention and change in control payments arising from the acquisition of the Company by the Buyer as contemplated by this Agreement (and without regard to any post-Closing action taken by the Company, any Subsidiary or the Buyer) as a result of obligations or agreements in effect prior to the Closing, and shall not include any line items that are not included on such Schedule 1.6. Except as set forth on Schedule 1.6, the amounts on each such line item shall be determined in accordance with GAAP.

(c) The Closing Balance Sheet delivered pursuant to Section 1.6(b) shall be accompanied by (i) all relevant backup materials and schedules, in detail reasonably acceptable to the Seller, and (ii) a statement setting forth the amount, if any, by which the Closing Working Capital is greater than, or less than, the Preliminary Closing Working Capital. The Buyer shall afford the authorized representatives of the Seller reasonable access upon reasonable notice and during normal business hours to such additional records as the Seller shall reasonably request in connection with its review of the Closing Balance Sheet; provided that such review shall not unreasonably interfere with the conduct of the businesses and operations of the Buyer, the Company or the Subsidiaries.

(d) In the event that the Seller disputes the Closing Balance Sheet or the calculation of the Closing Working Capital Adjustment (as defined below), the Seller shall notify the Buyer in writing (the “Dispute Notice”) of the amount, nature and basis of such dispute, within 30 calendar days after delivery of the Closing Balance Sheet. Any such Dispute Notice shall specify those items or amounts as to which the Seller disagrees, and the Seller shall be deemed to have agreed with all other items and amounts contained in the Closing Balance Sheet and the calculation of the Closing Working Capital Adjustment delivered pursuant to Sections 1.6(b) and 1.6(c). In the event of such a dispute, the Buyer and the Seller shall first use their Reasonable Best Efforts to reach agreement on the disputed items or amounts in order to determine the Closing Working Capital Adjustment, which amount shall not be less than the Buyer’s calculation delivered pursuant to Section 1.6(c) nor more than the Seller’s calculation

delivered pursuant to this Section 1.6(d). If the Buyer and the Seller are unable to resolve the dispute within 30 calendar days after delivery of the Dispute Notice, then any remaining items in dispute shall be submitted to the Neutral Accountant. All determinations and calculations pursuant to this Section 1.6(d) shall consider only those items or amounts on the Closing Balance Sheet or the Buyer’s calculation of Closing Working Capital as to which the Seller has disagreed, shall be in writing and shall be delivered to the Buyer and the Seller as promptly as practicable. The determination of the Neutral Accountant as to the resolution of any dispute shall be binding and conclusive upon all Parties. A judgment on the determination made by the Neutral Accountant pursuant to this Section 1.6 may be entered in and enforced by any court having jurisdiction thereover.

(e) The fees and expenses of the Neutral Accountant in connection with the resolution of disputes pursuant to Section 1.6(d) shall be shared equally by the Seller and the Buyer; provided that if the Neutral Accountant determines that one (1) such Party has adopted a position or positions with respect to the Closing Balance Sheet or the calculation of the Closing Working Capital Adjustment that is frivolous or clearly without merit, the Neutral Accountant may, in its discretion, assign a greater portion of any such fees and expenses to such Party.

(f) Immediately upon the expiration of the 30 calendar day period for giving the Dispute Notice, if no such notice is given, or upon notification by the Seller to the Buyer, that no such notice will be given, or immediately upon the resolution of disputes, if any, pursuant to this Section 1.6, (i) if the absolute difference between the Closing Working Capital as reflected on the Closing Balance Sheet and the Target Amount is less than or equal to the Working Capital Deductible, the Initial Purchase Price shall be increased or decreased by the opposite amount by which the Initial Purchase Price was initially increased or decreased pursuant to Section 1.2(c), if any, or (ii) if the absolute difference between the Closing Working Capital and the Target Amount is greater than the Working Capital Deductible, the Initial Purchase Price shall be (A) decreased to the extent the Closing Working Capital as reflected on the Closing Balance Sheet is less than the Preliminary Closing Working Capital as reflected on the Preliminary Closing Balance Sheet or (B) increased to the extent the Closing Working Capital as reflected on the Closing Balance Sheet exceeds the Preliminary Closing Working Capital as reflected on the Preliminary Closing Balance Sheet; provided, however, that any adjustment shall only be for amounts that are above and below the Target Amount by an amount greater than the Working Capital Deductible (such increased or decreased Initial Purchase Price, the “Adjusted Purchase Price”). Any difference between the Initial Purchase Price and the Adjusted Purchase Price shall be referred to herein as the “Closing Working Capital Adjustment” and shall be paid as follows:

(i) If the Closing Working Capital Adjustment is negative, then the Buyer shall be entitled to recover the Closing Working Capital Adjustment from the General Escrow Fund pursuant to the terms of the Escrow Agreement, and the Buyer and the Seller shall jointly notify the Escrow Agent within three (3) business days after such determination; and

(ii) If the Closing Working Capital Adjustment is positive, then, within 10 business days after such determination, the Buyer shall pay to the Seller an amount in immediately available funds equal to 90% of such Closing Working Capital Adjustment, and 10% of such Closing Working Capital Adjustment shall be deposited with the Escrow Agent pursuant to the Escrow Agreement and held in the General Escrow Fund.

(a) On the Closing Date, the Buyer shall deliver the General Escrow Amount to the Escrow Agent and establish the General Escrow Fund for purposes of (a) providing security for any adjustment to the amount of the Initial Purchase Price pursuant to Section 1.6 and (b) securing the indemnification obligations of the Equity Holders and the Seller set forth in Article VIII (but excluding Section 8.2). The General Escrow Fund shall be held by the Escrow Agent pursuant to the terms of the Escrow Agreement. The General Escrow Fund shall be held as a trust fund and shall not be subject to any Lien, attachment, trustee process or any other judicial process of any creditor of any party, and shall be held and disbursed solely for the purposes and in accordance with the terms of the Escrow Agreement.

(b) On the Closing Date, the Buyer shall deliver the Special Escrow Amount to the Escrow Agent and establish the Special Escrow Fund for purposes of securing the indemnification obligations of the Equity Holders and the Seller set forth in Article VIII with respect to the Special Obligations.

To the extent that amounts are so withheld by the Buyer, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the Seller.

After obtaining such written waivers and prior to the Closing Date, the Seller shall cause the Company to, and the Company shall and shall cause the Subsidiaries to, solicit stockholder approval of any and all such payments or benefits in a manner that satisfies the requirements for the exemption under Section 280G(b)(5)(A)(ii) of the Code and any regulations issued thereunder, including the provision of adequate disclosure to all applicable stockholders of all material facts concerning all payments that, in the absence of such stockholder approval, could be classified as “parachute payments” to a “disqualified individual” under Section 280G of the Code. The Seller shall cause the Company to, and the Company shall and shall cause the Subsidiaries to, provide such adequate disclosure to the applicable stockholders in a manner that satisfies Section 280G(b)(5)(B)(ii) of the Code and any regulations issued thereunder. The form of waiver, solicitation of approval, and disclosure materials shall be reasonably satisfactory to the Buyer, which shall be afforded a reasonable opportunity to review such documents before the waivers and approval are sought.

6.12 Seller Release. The Seller and each Equity Holder, on its, his or her own behalf and on behalf of its, his or her heirs, successors, trustees, executors, administrators, assigns and any other person or entity that may claim by, through or under any of them (collectively with the Seller and the Equity Holders, the “Releasors”) releases and discharges the Buyer and the Company and their respective present and future subsidiaries, directors, officers, agents, employees and representatives (collectively with the Buyer and the Company, as the case may be, the “Releasees”) from all actions, suits, causes of action and Liabilities of any kind or nature, whether in law or equity, and whether arisen, accrued or matured heretofore or hereafter, which against the Releasees, any of them, the Releasors, or any of them, ever had, now has or hereafter may have, upon or by reason of any cause, matter or thing whatsoever occurring prior to the date hereof (collectively, “Claims”), including (a) any Claims relating to or arising out of any securities of the Company held at any time by the Seller or any of the Equity Holders and (b) any dividends or distributions on such securities; provided, however, that notwithstanding anything in this Section 6.12 to the contrary, nothing herein shall be deemed a release or discharge of any obligation of the Buyer to perform any of the terms, conditions and agreements contained or referenced in this Agreement.

(a) From and after the Closing, the Buyer shall, to the fullest extent permitted by law, cause the Company and the Subsidiaries, for a period of six (6) years after the Closing, to honor all of the Company’s and the Subsidiaries’ obligations to indemnify and hold harmless each present and former director and officer of the Company and the Subsidiaries (the “Indemnified Parties”) against any costs or expenses (including attorneys’ fees), judgments, fines, losses, claims, damages, Liabilities or amounts paid in settlement incurred in connection with any claim, action, suit, proceeding or investigation, whether civil, criminal, administrative or investigative, arising out of or pertaining to matters existing or occurring at or prior to the Closing, whether asserted or claimed prior to, at or after the Closing, to the extent that such obligations to indemnify and hold harmless exist on the date of this Agreement; provided, however, that such indemnification obligations shall only be with respect to matters arising in connection with such director’s or officer’s service as a director or officer of the Company or any Subsidiary, and not in any other capacity; provided further, that in no event shall the Buyer, the Company or any Subsidiary have any obligation pursuant to this Section 6.13(a) with respect to matters for which the Buyer is entitled to indemnification pursuant to Section 8.1 or 8.2.

(b) Prior to the Closing, the Buyer shall purchase a six (6)-year pre-paid extended reporting period endorsement under the Company’s and the Subsidiaries’ current directors’ and officers’ liability insurance policy covering acts or omissions occurring prior to the Closing Date with respect to those directors and officers of the Company and the Subsidiaries who are currently covered by such policy on terms with respect to coverage and amount no less favorable to such directors and officers than those of such policy in effect on the date hereof; provided, however, that the Seller shall either (i) reimburse the Buyer for one-half of the premium for such extended reporting period endorsement prior to the Closing or (ii) accrue for one-half of the premium for such extended reporting period endorsement on both the Preliminary Closing Balance Sheet and the Closing Balance Sheet; provided further, that in no event shall the overall cost of such extended reporting period endorsement be more than $100,000.

(c) The provisions of this Section 6.13 are intended to be in addition to the rights otherwise available to the current directors and officers of the Company and the Subsidiaries by law, charter, by-laws, certificate of formation, limited liability company agreement, other organizational document or agreement, and shall operate for the benefit of, and shall be enforceable by, each of the Indemnified Parties, their heirs and their representatives.

If and to the extent (i) the Buyer or any of its Affiliates files one or more claims for indemnification pursuant to Article VIII with respect to a breach of Section 2.16 for failure to collect one or more accounts receivable within 330 days after the Closing Date, (ii) such claim(s) are paid out of the General Escrow Fund and (iii) the Buyer or any of its Affiliates subsequently collects all or a portion of such accounts receivable, then the Buyer shall promptly pay the entire collected amount to the Escrow Agent to be held as part of the General Escrow Fund.

(h) any of the matters denoted with “##” in the Disclosure Schedule and any claim with respect thereto.

8.2 Indemnification by the Equity Holders. If the Closing occurs, each Equity Holder, severally with respect to itself and not any other Equity Holder, shall indemnify the Buyer in respect of, and hold it harmless against, any and all Damages incurred or suffered by the Company, the Buyer or any Affiliate thereof resulting from, relating to or constituting:

(a) any breach, as of the date of this Agreement or as of the Closing Date, of any representation of such Equity Holder contained in Article IV of this Agreement; and

(b) any failure to perform any covenant or agreement of such Equity Holder contained in this Agreement or the Escrow Agreement.

(a) The Buyer shall give written notification to the Notified Party of the commencement of any Third Party Action. Such notification shall be given within 20 calendar days after receipt by the Buyer of notice of such Third Party Action, and shall describe in

reasonable detail (to the extent then known by the Buyer) the facts constituting the basis for such Third Party Action and the amount of the claimed damages. No delay or failure on the part of the Buyer in so notifying the Notified Party shall relieve the Equity Holders or the Seller of any Liability hereunder except to the extent of any damage or Liability caused by or arising out of such delay or failure. Within 20 calendar days after delivery of such notification, the Notified Party may, upon written notice thereof to the Buyer, assume control of the defense of such Third Party Action with counsel reasonably satisfactory to the Buyer; provided that (i) the Notified Party may only assume control of such defense if (A) it acknowledges in writing to the Buyer that any damages, fines, costs or other Liabilities that may be assessed against the Buyer in connection with such Third Party Action constitute Damages for which the Buyer shall be indemnified pursuant to this Article VIII, subject to the limitations set forth in this Article VIII, and (B) the ad damnum in such Third Party Action, taken together with the estimated costs of defense thereof and the Claimed Amount with respect to any unresolved claims for indemnification then pending, is less than or equal to 150% of the current balance of the General Escrow Fund, in the case of a Third Party Action that is unrelated to the Special Obligations, or 150% of the current aggregate balance of the General Escrow Fund and the Special Escrow Fund, in the case of a Third Party Action that relates to the Special Obligations, and (ii) the Notified Party may not assume control of the defense of any Third Party Action involving Taxes (except to the extent separately addressed in Section 9.4) or criminal Liability or in which equitable relief is sought against the Buyer. If the Notified Party does not, or is not permitted under the terms hereof to, so assume control of the defense of a Third Party Action, the Buyer shall control such defense. The Non-Controlling Party may participate in such defense at its own expense. The Controlling Party shall keep the Non-Controlling Party advised of the status of such Third Party Action and the defense thereof and shall consider in good faith recommendations made by the Non-Controlling Party with respect thereto. The Non-Controlling Party shall furnish the Controlling Party with such information as it may have with respect to such Third Party Action (including copies of any summons, complaint or other pleading which may have been served on such party and any written claim, demand, invoice, billing or other document evidencing or asserting the same) and shall otherwise cooperate with and assist the Controlling Party in the defense of such Third Party Action. The fees and expenses of counsel to the Buyer with respect to a Third Party Action shall be considered Damages for purposes of this Agreement if (i) the Buyer controls the defense of such Third Party Action pursuant to the terms of this Section 8.3(a) or (ii) the Notified Party assumes control of such defense and the Buyer has conflicting interests or different defenses available with respect to such Third Party Action. The Notified Party shall not agree to any settlement of, or the entry of any judgment arising from, any Third Party Action without the prior written consent of the Buyer, which shall not be unreasonably withheld, conditioned or delayed; provided that the consent of the Buyer shall not be required if the Notified Party agrees in writing to pay any amounts payable pursuant to such settlement or judgment and such settlement or judgment includes a complete release of the Buyer from further Liability and has no other adverse effect on the Buyer. Except as provided in Section 8.3(f) below, the Buyer shall not agree to any settlement of, or the entry of any judgment arising from, any such Third Party Action without the prior written consent of the Notified Party, which shall not be unreasonably withheld, conditioned or delayed.

(b) In order to seek indemnification under this Article VIII, the Buyer shall deliver a Claim Notice to the Notified Party (with a copy to the Seller in the case of a claim pursuant to Section 8.2).

(c) Within 30 calendar days after delivery of a Claim Notice, the Notified Party shall deliver to the Buyer a Response, in which the Notified Party shall (i) agree that the Buyer is entitled to receive all of the Claimed Amount (in which case (A) if the indemnification was sought pursuant to Section 8.1, the Response shall be accompanied by a letter from the Seller instructing the Escrow Agent to disburse to the Buyer from the General Escrow Fund or the Special Escrow Fund, as applicable, an amount in cash equal to the Claimed Amount or (b) if the indemnification was sought pursuant to Section 8.2, the Response shall be accompanied by an amount in immediately available funds equal to the Claimed Amount), (ii) agree that the Buyer is entitled to receive the Agreed Amount (in which case (A) if the indemnification was sought pursuant to Section 8.1, the Response shall be accompanied by a letter from the Seller instructing the Escrow Agent to disburse to the Buyer from the General Escrow Fund or the Special Escrow Fund, as applicable, an amount in cash equal to the Agreed Amount or (b) if the indemnification was sought pursuant to Section 8.2, the Response shall be accompanied by an amount in immediately available funds equal to the Agreed Amount) or (iii) dispute that the Buyer is entitled to receive any of the Claimed Amount. The Notified Party may contest the payment of all or a portion of the Claimed Amount only based upon a good faith belief that all or such portion of the Claimed Amount does not constitute Damages for which the Buyer is entitled to indemnification under this Article VIII. If no Response is delivered by the Notified Party within such 30-day period, and (i) indemnification was sought by the Buyer pursuant to Section 8.1, the Equity Holders and the Seller shall be deemed to have agreed that all of the Claimed Amount is owed to the Buyer or (ii) indemnification was sought by the Buyer pursuant to Section 8.2, the applicable Equity Holder shall be deemed to have agreed that all of the Claimed Amount is owed to the Buyer. Acceptance by the Buyer of partial payment of any Claimed Amount shall be without prejudice to the Buyer’s right to claim the balance of any such Claimed Amount.

(d) During the 30-day period following the delivery of a Response that reflects a Dispute, the Notified Party and the Buyer shall use good faith efforts to resolve the Dispute. If the Dispute is not resolved within such 30-day period, the Notified Party and the Buyer shall discuss in good faith the submission of the Dispute to binding arbitration, and if the Notified Party and the Buyer agree in writing to submit the Dispute to such arbitration, then the provisions of Section 8.3(e) shall become effective with respect to such Dispute. The provisions of this Section 8.3(d) shall not obligate the Notified Party and the Buyer to submit to arbitration or any other alternative dispute resolution procedure with respect to any Dispute, and in the absence of an agreement by the Notified Party and the Buyer to arbitrate a Dispute, such Dispute shall be resolved in a state or federal court sitting in the Commonwealth of Massachusetts, in accordance with Section 12.11. If the Buyer is seeking to enforce the claim that is the subject of the Dispute pursuant to the Escrow Agreement, the Seller and the Buyer shall deliver to the Escrow Agent, promptly following the resolution of the Dispute (whether by mutual agreement, arbitration, judicial decision or otherwise), a written notice executed by both parties instructing the Escrow Agent as to what (if any) portion of the General Escrow Fund or the Special Escrow Fund, as applicable, shall be distributed to the Buyer (which notice shall be consistent with the terms of the resolution of the Dispute). If the Buyer is seeking to enforce the claim pursuant to Section 8.2 of this Agreement, the applicable Equity Holder shall deliver to the Buyer, promptly following the resolution of the Dispute (whether by mutual agreement, arbitration, judicial decision or otherwise), an amount in immediately available funds equal to the amount provided for in the resolution of the Dispute.

(e) If, as set forth in Section 8.3(d), the Buyer and the Notified Party agree to submit any Dispute to binding arbitration, the arbitration shall be conducted by a single arbitrator (the “Arbitrator”) in accordance with the Commercial Rules in effect from time to time and the following provisions:

(i) In the event of any conflict between the Commercial Rules in effect from time to time and the provisions of this Agreement, the provisions of this Agreement shall prevail and be controlling;

(ii) Either party shall commence the arbitration by filing a written submission with the Boston, Massachusetts office of the AAA in accordance with Commercial Rule 5 (or any successor provision);

(iii) All depositions or other discovery shall be conducted pursuant to the applicable U.S. federal rules relating to discovery;

(iv) Not later than 30 calendar days after the conclusion of the arbitration hearing, the Arbitrator shall prepare and distribute to the parties a writing setting forth the arbitral award and the Arbitrator’s reasons therefor. Any award rendered by the Arbitrator shall be final, conclusive and binding upon the parties, and judgment thereon may be entered and enforced in any court of competent jurisdiction (subject to Section 12.11);

(v) The Arbitrator shall have no power or authority, under the Commercial Rules or otherwise, to (A) modify or disregard any provision of this Agreement, including the provisions of this Section 8.3(e), or (B) address or resolve any issue not submitted by the parties; and

(vi) In connection with any arbitration proceeding pursuant to this Agreement, each party shall bear its own costs and expenses, except that the fees and costs of the AAA and the Arbitrator, the costs and expenses of obtaining the facility where the arbitration hearing is held, and such other costs and expenses as the Arbitrator may determine to be directly related to the conduct of the arbitration and appropriately borne jointly by the parties (which shall not include any party’s attorneys’ fees or costs, witness fees (if any), costs of investigation and similar expenses) shall be shared equally by (i) the Buyer and the Seller, if the indemnification was sought by the Buyer pursuant to Section 8.1 of this Agreement, and (ii) the Buyer and the applicable Equity Holder, if the indemnification was sought by the Buyer pursuant to Section 8.2 of this Agreement.

(f) Notwithstanding the other provisions of this Section 8.2, if a party to any agreement listed in Section 8.3(f) of the Disclosure Schedule asserts (other than by means of a lawsuit) that the Buyer is liable to such party for a monetary or other obligation which may constitute or result in Damages for which the Buyer may be entitled to indemnification pursuant to this Article VIII, and the Buyer reasonably determines that it has a valid business reason to fulfill such obligation, then (i) the Buyer shall be entitled to satisfy such obligation, without prior notice to or consent from the Notified Party, (ii) the Buyer may subsequently make a claim for indemnification in accordance with the provisions of this Article VIII and (iii) the Buyer shall be reimbursed, in accordance with the provisions of this Article VIII, for any such Damages for

which it is entitled to indemnification pursuant to this Article VIII (subject to the right of the Notified Party to dispute the Buyer’s entitlement to indemnification, or the amount for which it is entitled to indemnification, under the terms of this Article VIII).

(g) The Seller shall have full power and authority on behalf of each Equity Holder to take any and all actions on behalf of, execute any and all Responses and other instruments on behalf of, and execute or waive any and all rights of, the Equity Holders with respect to indemnification claims made under Section 8.1 of this Agreement. The Seller shall have no Liability to any Equity Holder for any action taken or omitted on behalf of the Equity Holders pursuant to this Section 8.3(g).

(a) Unless otherwise specified in this Section 8.4 or elsewhere in this Agreement, all provisions of this Agreement shall survive the Closing and the consummation of the transactions contemplated hereby and shall continue forever in full force and effect in accordance with their terms. Except for claims based on fraud or knowing misrepresentation, all representations and warranties that are covered by the indemnification obligations in Sections 8.1(a) and 8.2(a) shall expire on the date 18 months following the Closing Date; provided, however, that the representations and warranties set forth in Sections 2.9 and 3.7 and (to the extent relating to Taxes) Sections 2.20 and 2.21 (collectively, the “Tax-Related Representations”) and Sections 2.2, 2.3, 3.2, 4.2 and 5.2 (collectively, the “Constitutive Representations”) shall survive for the duration of the period ending 30 calendar days following the expiration of the applicable statute of limitations. All matters described in this Section 8.4(a) that do not expire on the date 18 months following the Closing Date are collectively referred to herein as “Permitted Matters.”

(b) If the Buyer delivers to the Notified Party, before expiration of a representation, warranty, covenant or agreement, a Claim Notice based upon a breach of such representation, warranty, covenant or agreement, then the applicable representation, warranty, covenant or agreement shall survive until, but only for purposes of, the resolution of the matter covered by such notice. If a Claim Notice is given with respect to a legal proceeding instituted by or written claim made by a third party and such legal proceeding or written claim is definitively withdrawn or resolved in favor of the Buyer, the Buyer shall promptly so notify the Notified Party. The rights to indemnification set forth in this Article VIII shall not be affected by (i) any investigation conducted by or on behalf of the Buyer or any knowledge acquired (or capable of being acquired) by the Buyer, whether before or after the date of this Agreement or the Closing Date, with respect to the inaccuracy or non-compliance with any representation, warranty, covenant or obligation which is the subject of indemnification hereunder, or (ii) any waiver by the Buyer of any closing condition relating to the accuracy of representations and warranties or the performance of or compliance with agreements and covenants.

(a) With respect to claims for Damages arising under Section 8.1(a), 8.1(h) or 8.2(a), the Equity Holders and the Seller shall not be liable for any such Damages until the aggregate amount of all such Damages under Sections 8.1(a), 8.1(h) and 8.2(a) exceeds $450,000

(at which point the Equity Holders and the Seller shall become liable only for aggregate Damages under Sections 8.1(a), 8.1(h) and 8.2(a) in excess of $450,000); provided that the limitation set forth in this sentence shall not apply to (i) claims based on fraud or knowing misrepresentation or (ii) any claim pursuant to Section 8.1(a), 8.1(h) or 8.2(a) relating to a breach of the Tax-Related Representations, the Constitutive Representations or the representations and warranties set forth in Sections 2.27, 3.8 or 4.5.

(b) Except for claims based on (i) fraud or knowing misrepresentation, (ii) a breach of the Tax-Related Representations or Section 9.2 or (iii) the Constitutive Representations, the General Escrow Fund shall be the exclusive means for the Buyer to collect any Damages for which it is entitled to indemnification under Sections 8.1(a) and 8.1(h) from any Equity Holder or the Seller. Without limiting the foregoing, the Buyer shall not attempt to collect any Damages with respect to a claim for indemnification under Section 8.1(a) or 8.1(h) directly from any Equity Holder or the Seller unless there are insufficient unclaimed General Escrow Funds remaining to satisfy such Damages pursuant to the Escrow Agreement. The General Escrow Fund and the Special Escrow Fund shall be the exclusive means for the Buyer to collect any Damages for which it is entitled to indemnification with respect to the Special Obligations. Any claims for Damages with respect to the Special Obligations shall be satisfied first from the Special Escrow Fund and then, if the Special Escrow Fund is insufficient, from the General Escrow Fund. Neither the General Escrow Fund nor the Special Escrow Fund shall be available for claims arising under Section 8.2, which claims shall be solely the obligation of the applicable Equity Holder.

(c) Notwithstanding anything to the contrary in this Agreement, but subject to the limitations set forth in Sections 8.5(a) and (b) and except for claims based on fraud or knowing misrepresentation, (i) the aggregate Liability of the Equity Holders and the Seller for all Damages under this Agreement shall not exceed 40% of the Adjusted Purchase Price and, for each Equity Holder and the Seller, shall not exceed 40% of its pro rata percentage of the Adjusted Purchase Price (including such Equity Holder’s and the Seller’s pro rata percentage of the General Escrow Fund and the Special Escrow Fund), and (ii) the aggregate Liability of the Equity Holders and the Seller for any claim made under this Agreement shall not exceed the aggregate amount of Damages for such claim and, except with respect to Damages under Section 8.2, for each Equity Holder and the Seller, shall not exceed its pro rata percentage of the aggregate amount of Damages for such claim. With respect to the preceding sentence, the pro rata percentages of the Equity Holders and the Seller, both individually and collectively, shall be as set forth on Schedule 8.5(c) attached hereto. The aggregate Liability of each Equity Holder for Damages under Section 8.2 shall be limited to matters involving such Equity Holder, and no Equity Holder shall have any Liability for Damages under Section 8.2 as a result of matters involving any other Equity Holder. The Seller shall not have any Liability for Damages under Section 8.2.

(d) The Equity Holders and the Seller shall not have any right of contribution against the Company with respect to any breach by the Company of any of its representations, warranties, covenants or agreements.

(e) Except with respect to claims based on fraud or knowing misrepresentation and claims arising under Article IX, after the Closing, the rights of the Buyer

under this Article VIII shall be the exclusive remedy of the Buyer with respect to claims resulting from or relating to any misrepresentation, breach of warranty or failure to perform any covenant or agreement of any Equity Holder, the Seller or the Company contained in this Agreement.

(a) The Seller shall cause to be prepared and timely filed all Tax Returns of the Company and each Subsidiary required to be filed (taking into account extensions) prior to the Closing Date.

(b) The Buyer shall prepare and timely file or shall cause to be prepared and timely filed all Tax Returns not filed on or before the Closing Date, including Tax Returns which were required to be filed before the Closing but were not filed and all other Tax Returns with respect to the Company or any Subsidiary or in respect of their businesses, assets or operations. The Buyer shall make all payments required with respect to any such Tax Returns; provided, however, that the Seller and the Equity Holders shall, within 15 calendar days after receipt of written notification that such a payment was made by the Buyer, reimburse the Buyer to the extent any payment the Buyer is required to make relates to the operations of the Company or any Subsidiary for any period ending (or deemed pursuant to Section 9.3(b) to end) on or before the Closing Date to the extent such portion of the payment exceeds the amount of the accruals for Taxes (excluding accruals and reserves for deferred Taxes established to reflect timing differences between book and Tax income) set forth on the Closing Balance Sheet.
