               (f) Effects on Edge Interests and Summit Interests in the Mergers. As of the Effective Time, by virtue of the Mergers and without any action on the part of the Edge Holders or the Summit Holders, the outstanding Edge Interests and Summit Interests shall cease to be outstanding and shall be converted into the right to receive, at the Effective Time:

                         (ii) in respect of each Edge Interest or Summit Interest held by a Non-Accredited Holder, the Merger Consideration payable at Closing to such Non-Accredited Holder solely in cash in the amount specified as payable to such Non-Accredited Holder in Section 2.2.

               (g) Effects on Merger Sub Interests in the Mergers. Each membership interest of Merger Sub I outstanding immediately prior to the Effective Time shall be converted into one membership interest of the Edge Surviving Entity, and the Edge Surviving Entity shall be a wholly-owned Subsidiary of Parent. Each membership interest of Merger Sub II outstanding immediately prior to the Effective Time shall be converted into one membership interest of the Summit Surviving Entity, and the Summit Surviving Entity shall be a wholly-owned Subsidiary of Parent.

          2.2 Merger Consideration.

               (a) The aggregate consideration payable by the Buyer Parties to the (i) the Edge Holders at the Closing in connection with the transactions contemplated by this Agreement (the “Edge Merger Consideration”) and (ii) the Summit Holders at the Closing in connection with the transactions contemplated by this Agreement (the “Summit Merger Consideration” and, together with the Edge Merger Consideration, the “Merger Consideration”) shall be equal to:

                         (iii) the Estimated Buyer Working Capital Payment (if any); plus

                         (iv) the Estimated CapEx Reimbursement Amount; minus

          The Merger Consideration shall be subject to further adjustment after the Closing pursuant to Article III.

               (b) On the terms and subject to the conditions set forth in this Agreement, the Merger Consideration shall be payable at the Closing as follows:

                         (i) 7,549,223 shares of Parent Common Stock (the “Parent Share Consideration”), which is equal to the number obtained by dividing (i) $136,000,000 by (ii) $18.0151, which is the Market Price on the Execution Date, shall be issued as follows:

                              (A) all shares of Parent Share Consideration other than the Escrow Shares described in Section 2.2(b)(i)(B) shall be issued directly to the Accredited Holders at Closing in the proportions set forth opposite each Accredited Holder’s name in a schedule to be delivered by the Agent to the Buyer Parties no later than two Business Days prior to the Closing Date (the “Merger Consideration Schedule” ); and

                              (B) a number of shares of Parent Share Consideration (the “Escrow Shares”) with an aggregate Market Price on the Execution Date that, together with the Escrow Cash Deposit, equals 7.5% of the Base Consideration (the “Escrow Shares”) will be issued in the names of the Accredited Holders in the proportions set forth opposite each Accredited Holder’s name on the Merger Consideration Schedule and deposited with the Escrow Agent at Closing on behalf of such Accredited Holders, to be held and disbursed by the Escrow Agent from the Escrow Account in accordance with Article IV and the terms of the Escrow Agreement;

                         (ii) a cash amount equal to $2,500,000 (the “Reimbursement Fund Amount”) will be deposited with the Agent by wire transfer of immediately available funds in accordance with the wire transfer instructions provided by the Agent, which wire transfer instructions shall be specified by the Agent to the Buyer Parties no less than two Business Days prior to the Closing Date; and

                         (iii) an aggregate amount in cash (the “Cash Amount”) equal to the difference between (1) the Merger Consideration and (2) the sum of $136,000,000 and the Reimbursement Fund Amount will be paid at Closing as follows:

                              (A) subject to the deposit of the Escrow Cash Deposit pursuant to Section 2.2(b)(iii)(B), the Cash Amount shall be paid to the Holders at Closing by wire transfer of immediately available funds in the amounts and in accordance with the wire transfer instructions set forth opposite each Holder’s name on the Merger Consideration Schedule (it being acknowledged and agreed that the Non-Accredited Holders shall receive only cash Merger Consideration and will therefore receive disproportionately more of the Cash Amount than the Accredited Holders); and

                              (B) an amount equal to 7.5% of the portion of the Cash Amount that would be payable to the Non-Accredited Holders pursuant to Section 2.2(b)(iii)(A) in the absence of this Section 2.2(b)(iii)(B) (the “Escrow Cash Deposit”) will be deposited with the Escrow Agent at Closing on behalf of the Non-Accredited Holders in the proportions set forth opposite each Non-Accredited Holder’s name on the Merger Consideration Schedule, to be held and disbursed by the Escrow Agent from the Escrow Account in accordance with Article IV and the terms of the Escrow Agreement.

                         (iv) Edge Holding shall direct in the Merger Consideration Schedule that the Merger Consideration (including the Escrow Shares) that would otherwise be payable to it under this Agreement shall instead be issued and paid directly to the holders of equity interests in Edge Holding, in the proportions to be set forth in the Merger Consideration Schedule (which proportions shall reflect such holders’ relative ownership interests of Edge Holding).

          2.3 Payment of Debt Payoff Amount. At the Closing, the Buyer Parties will pay, or cause to be paid, the Debt Payoff Amount, if any, on behalf of the Seller Parties to the applicable lenders in accordance with Section 10.3(e).

          2.4 Payment of Transaction Costs. At the Closing, the Buyer Parties will pay, or cause to be paid, the Transaction Costs, if any, on behalf of the Seller Parties to the applicable service providers in accordance with Section 10.3(f).

          2.5 Payment of Change of Control Payments. At the Closing, except as set forth on Schedule 2.2(a)(vii), the Buyer Parties will transfer, or cause to be transferred, to the applicable Acquired Company’s payroll account cash in the amount of the Change of Control Payments to be made on behalf of the Acquired Companies in accordance with Section 10.3(g), which Change of Control Payments shall be paid to certain Holders and Employees on behalf of the Acquired Companies as provided in Section 8.19 below.

          2.6 Deliveries and Actions at Closing. At the Closing (a) the Seller Parties will deliver or cause to be delivered to the Buyer Parties, and the Buyer Parties will deliver or cause to be delivered to the Seller Parties, the various certificates, instruments and documents required to be delivered pursuant to Article X, (b) the Seller Parties shall take or cause to be taken the actions required to be taken by the Seller Parties pursuant to Article X and (c) the Buyer Parties shall take or cause to be taken the actions required to be taken by the Buyer Parties pursuant to Article X.

          2.7 Tax Treatment of Transactions. For U.S. federal income tax purposes (and for purposes of any applicable state or local Tax purposes that follow the U.S. federal income tax treatment), the Parties agree to treat the transactions contemplated by this Agreement consistent with Situation 2 of Revenue Ruling 99-6, 1999-1 CB 432 (1/15/1999). The Parties agree to file all Tax Returns consistent with the foregoing, and not to take any position inconsistent with this treatment, unless and until there has been a Final Determination to the contrary. The Parties also agree that the Acquired Companies’ obligations to pay the Debt Payoff Amount, the Transaction Costs and the Change of Control Payments shall have accrued as of the Closing Date, and the Holders and the Acquired Companies (as distinguished from the Buyer Parties and the Surviving Entities) shall be entitled to any deductions relating to such payment obligations for U.S. federal income tax purposes (and for Texas franchise purposes and for purposes of any applicable state or local Taxes that follow the federal treatment). The Acquired Companies shall take into account such deductions on their respective Forms 1065 (U.S. Return of Partnership Income) and any applicable state or local income tax returns that follow the federal treatment for their taxable years ending on or before the Closing Date (it being understood that each of the Acquired Companies will terminate as a partnership under Section 708(b)(1)(A) of the Code as a result of the transactions contemplated by this Agreement and thus its final taxable year for such purposes will end on the Closing Date).

          2.8 Allocation of Merger Consideration. The Parties agree to cooperate in good faith to agree upon an allocation of the Merger Consideration, as finally determined pursuant to Section 2.2, and such other consideration required to be taken into account, and as may be required to be adjusted to take into account the treatment of the Escrow Cash as the property of the Buyer Parties for U.S. federal income tax purposes, among the Acquired Assets in accordance with this Section 2.8 and Sections 755 and 1060 of the Code and the Treasury Regulations thereunder. On or prior to the date that is 90 days after the determination of the Final Closing Date Balance Sheets, the Final Net Working Capital and the Final CapEx Reimbursement Amount in accordance with Section 3.2(b) and taking into account any adjustments to the Merger Consideration pursuant to Section 3.2, the Buyer Parties shall prepare a schedule allocating the Merger Consideration (subject to such adjustments and any further adjustments required to be taken into account to reflect the treatment of the Escrow Cash as the property of the Buyer Parties) and other amounts paid by the Buyer Parties to the Seller Parties among the Acquired Assets, including the covenant in Section 8.5, in accordance with this Section 2.8 and Sections 755 and 1060 of the Code and the Treasury Regulations thereunder (the “Asset Allocation”). Within 30 days after the receipt of the Asset Allocation, the Agent shall provide written notice to the Buyer Parties of any changes to the Asset Allocation or otherwise shall be deemed to have agreed with the Asset Allocation. If the Agent proposed changes to the Asset Allocation and the Agent and the Buyer Parties cannot agree upon a revised Asset Allocation within 30 days following the Agent’s written notice, then the Buyer Parties shall engage the Independent Accountant to resolve such dispute. The Independent Accountant shall review the disputed matters and as promptly as practicable deliver to the Buyer Parties and the Agent a statement setting forth its determination as to the proper treatment of the matters in dispute, and such determination shall constitute the final Asset Allocation and shall be final and binding upon the Parties without any further right of appeal. All charges of the Independent Accountant and other expenses directly incurred in making such determination shall be borne by the Party against whom the majority of items were determined (based on amounts in dispute). If, subsequent to the Closing, there occurs any increase or decrease in the consideration paid for the Acquired Interests within the meaning of Treasury Regulations Sections 1.1060-1(e)(1)(ii)(B), the Parties shall adjust the Asset Allocation in a manner consistent with this Section 2.8, including the dispute resolution process contained herein. The Parties shall not file any Tax Return or otherwise take, or permit any Affiliate to take, any position with respect to Taxes which is inconsistent with such Asset Allocation, except as required by Law following a Final Determination.

ARTICLE III
MERGER CONSIDERATION ADJUSTMENT

          3.1 Estimated Merger Consideration Adjustment Procedures.

               (a) The Parties acknowledge that the Merger Consideration has been based in part on the Acquired Companies having an aggregate minimum Net Working Capital as of the Closing Date equal to $20,614,048 (the “Net Working Capital Threshold”). The Cash Amount delivered at the Closing pursuant to Section 2.2 shall be adjusted in accordance with the procedures set forth in this Section 3.1. The Agent shall prepare and deliver, or cause to be prepared and delivered, to the Buyer Parties, no later than two Business Days prior to the Closing Date, (i) an estimated balance sheet of each of the Acquired Companies as of the

Closing Date, each of which balance sheets will be prepared in accordance with GAAP, applied consistently with the classifications, judgments, valuation methodologies and estimation methodologies used historically by the applicable Acquired Company, except that such balance sheets shall be prepared using the non-GAAP classifications, judgments and methodologies set forth on Annex B (the “Agreed NWC Accounting Principles”); provided, however, that, even if inconsistent with GAAP as so applied or the Agreed NWC Accounting Principles, such balance sheets shall not take into account the transactions contemplated by this Agreement (the balance sheets prepared in accordance with the foregoing are referred to as the “Estimated Closing Date Balance Sheets”) and (ii) an estimate of the CapEx Reimbursement Amount (the “Estimated CapEx Reimbursement Amount”). The Agent shall also prepare and deliver, or cause to be prepared and delivered, to the Buyer Parties a worksheet showing the Net Working Capital shown on the Estimated Closing Date Balance Sheets (the “Estimated Net Working Capital”).

               (b) If the Estimated Net Working Capital exceeds the Net Working Capital Threshold (such excess, the “Estimated Buyer Working Capital Payment”), the Merger Consideration delivered at the Closing pursuant to Section 2.2 shall be increased by an amount equal to the Estimate Buyer Working Capital Payment (as contemplated by Section 2.2).

               (c) If the Net Working Capital Threshold exceeds the Estimated Net Working Capital (such excess, the “Estimated Holders Working Capital Payment”), the Merger Consideration delivered at the Closing pursuant to Section 2.2 shall be reduced by an amount equal to the Estimated Holders Working Capital Payment (as contemplated by Section 2.2).

               (d) The Merger Consideration delivered at the Closing pursuant to Section 2.2 shall be increased by an amount equal to the Estimated CapEx Reimbursement Amount (as contemplated by Section 2.2).

          3.2 Final Merger Consideration Adjustment Procedures.

               (a) For the purpose of confirming the Estimated Working Capital Payment or the Estimated Buyer Working Capital Payment, as applicable, and the Estimated CapEx Reimbursement Amount, the Buyer Parties shall prepare, or cause to be prepared, (i) a balance sheet of each of the Acquired Companies as of the Closing Date, each of which balance sheets will be prepared in accordance with GAAP, applied consistently with the classifications, judgments, valuation methodologies and estimation methodologies used to prepare the Estimated Closing Date Balance Sheets, except that such balance sheets shall be prepared using the Agreed NWC Accounting Principles; provided, however, that, even if inconsistent with GAAP as so applied or the Agreed NWC Accounting Principles, the balance sheets shall not take into account the transactions contemplated by this Agreement (the balance sheets prepared in accordance with the foregoing are referred to as the “Final Closing Date Balance Sheets”) and (ii) a schedule of the CapEx Reimbursement Amount (the “Final CapEx Reimbursement Schedule”).

               (b) No later than 60 days after the Closing Date, the Buyer Parties shall deliver to the Agent the Final Closing Date Balance Sheets and the Final CapEx

Reimbursement Schedule together with a worksheet showing the difference, if any, between (i) the Net Working Capital shown on the Final Closing Date Balance Sheets (the “Final Net Working Capital”) and the Estimated Net Working Capital and (ii) the CapEx Reimbursement Amount shown on the Final CapEx Reimbursement Schedule (the “Final CapEx Reimbursement Amount”) and the Estimated CapEx Reimbursement Amount. If within 30 days after the date of the delivery to the Agent of the Final Closing Date Balance Sheets and the Final CapEx Reimbursement Schedule the Agent determines in good faith that the Agent disagrees with any portion of the Final Closing Date Balance Sheets or the Final CapEx Reimbursement Schedule and the amount of such disagreement exceeds $25,000 (any such disputed items being the “Disputed Items”), then the Agent may deliver a written notice (a “Dispute Notice”) to the Buyer Parties within such 30-day period, which Dispute Notice shall: (i) set forth the Agent’s proposed resolution of the Disputed Items (including the Agent’s determination of Net Working Capital or the CapEx Reimbursement Amount (as applicable) taking into account such proposed resolution of the Disputed Items) and (ii) include materials showing in reasonable detail the Agent’s support for such position. Any matters impacting the calculation of Final Net Working Capital or the Final CapEx Reimbursement Amount that are not included as Disputed Items in a timely delivered Dispute Notice and that are not affected by the resolution of Disputed Items shall be deemed accepted by the Agent and shall be binding and final for all purposes of this Agreement, and (A) the failure by the Agent to provide a Dispute Notice within such 30-day period or (B) the delivery by the Agent to the Buyer Parties during such 30-day period of a written notice stating that the Agent has elected not to deliver a Dispute Notice, will constitute a full and complete acceptance of the Final Closing Date Balance Sheets and the Final CapEx Reimbursement Schedule as determined by the Buyer Parties and such Final Closing Date Balance Sheets and such Final CapEx Reimbursement Schedule shall be binding and final for all purposes of this Agreement. Until the final determination of the Final Closing Date Balance Sheets, the Final Net Working Capital, the Final CapEx Reimbursement Schedule and the Final CapEx Reimbursement Amount in accordance with this Section 3.2(b), the Agent and its representatives shall have full access to the Books and Records, the personnel of, and work papers prepared by, the Buyer Parties and/or the Buyer Parties’ representatives to the extent that they relate to such matters and to such historical financial information (to the extent in Buyer Parties’ possession) relating to such matters as Agent may reasonably request for the purpose of reviewing the Final Closing Date Balance Sheets and the Final CapEx Reimbursement Schedule and the determination of the Final Net Working Capital and the Final CapEx Reimbursement Amount and to prepare a Dispute Notice; provided that such access shall be in a manner that does not unreasonably interfere with the normal business operations of the Buyer Parties or the Acquired Companies. If the Buyer Parties and the Agent are unable to resolve any disagreement among them with respect to such matters within 15 days (or such longer period as mutually agreed to by the Agent and the Buyer Parties) after the delivery of a Dispute Notice by the Agent to the Buyer Parties, then the Disputed Items (but no others) may be referred by the Agent or the Buyer Parties for determination to Ernst & Young LLP (or, if they are unable or unwilling to serve, another nationally recognized accounting firm not affiliated with the Seller Parties or the Buyer Parties that is mutually selected by the Agent and the Buyer Parties). If the Agent and the Buyer Parties are unable to select a nationally recognized accounting firm within five Business Days of Ernst & Young LLP declining to accept such engagement, either the Agent or the Buyer Parties may

thereafter request that the American Arbitration Association make such selection (as applicable, Ernst & Young LLP, the firm selected by the Agent and the Buyer Parties or the firm selected by the American Arbitration Association is referred to as the “Independent Accountant”). Each of the Agent and the Buyer Parties (acting collectively) shall provide the Independent Accountant and the other party with a statement of its position as to the amount for each Disputed Item within 15 days from the date of the referral. The Independent Accountant shall make a written determination as promptly as practicable, but in any event within 30 days after the date on which the dispute is referred to the Independent Accountant, by selecting from the position of either the Agent (on one hand) or the Buyer Parties (on the other hand) as to the amount of the Disputed Items. The Independent Accountant shall be authorized to select only the position as to the amount of Final Net Working Capital or the Final CapEx Reimbursement Amount (as applicable) as presented by either the Agent (on the one hand) or the Buyer Parties (on the other hand). The Independent Accountant shall have no power to reach any other result and shall select the Final Net Working Capital or the Final CapEx Reimbursement Amount (as applicable) that, in its judgment, is the closest to being in conformity with this Agreement. If at any time the Agent and the Buyer Parties resolve their dispute, then notwithstanding the preceding provisions of this Section 3.2(b), the Independent Accountant’s involvement promptly shall be discontinued and the Final Closing Date Balance Sheets or the Final CapEx Reimbursement Schedule (as applicable) shall be revised, if necessary, to reflect such resolution and thereupon shall be final and binding for all purposes of this Agreement. The Parties shall make readily available to the Independent Accountant all relevant Books and Records relating to such matters and all other items reasonably requested by the Independent Accountant in connection with resolving the Disputed Items. The costs and expenses of the Independent Accountant shall be borne by the Parties whose position as to the amount of the Disputed Items was not selected by the Independent Accountant. The decision of the Independent Accountant shall be final and binding for all purposes of this Agreement and the Final Closing Date Balance Sheets or the Final CapEx Reimbursement Schedule (as applicable) shall be revised, if necessary, to reflect such decision and thereupon shall be final and binding for all purposes of this Agreement.

               (c) Following the final determination of the Final Net Working Capital and the Final CapEx Reimbursement Amount in accordance with Section 3.2(b), the Buyer Parties or the Agent (on behalf of the Holders), as applicable, shall make or cause to be made such true-up payments to one another as are required to place the Buyer Parties and the Holders in the same position in which they would have been had the Final Closing Date Balance Sheets, the Final Net Working Capital, the Final CapEx Reimbursement Schedule and the Final CapEx Reimbursement Amount been known at the Closing and had the Final Net Working Capital and the Final CapEx Reimbursement Amount, rather than the Estimated Net Working Capital and the Estimated CapEx Reimbursement Amount, been used to determine the Merger Consideration at the Closing.

               (d) Any true-up payment required to be made by the Agent pursuant to Section 3.2(c) is referred to as the “Final Holders Payment.” If the Agent is required to make the Final Holders Payment, then (i) the Agent (on behalf of the Holders) shall promptly (but in any event within five Business Days) pay an amount equal to the Final Holders Payment to an account designated by the Buyer Parties in accordance with Section 13.2 by wire transfer of immediately available funds from the Reimbursement Fund Amount and (ii) to the extent the

Final Holders Payment exceeds the then remaining balance of the Reimbursement Fund Amount, the Agent shall notify the Buyer Parties thereof and the Agent and the Buyer Parties shall promptly (but in any event within five Business Days) issue Joint Instruction Letters to the Escrow Agent instructing the Escrow Agent to release from the Escrow Account Escrow Funds in an aggregate amount equal to the remaining portion of the Final Holders Payment to the Buyer Parties (with respect to any Escrow Shares so released) or to an account designated by the Buyer Parties in accordance with Section 13.2 by wire transfer of immediately available funds (with respect to any Escrow Cash so released) within three Business Days of receipt of such Joint Instruction Letters and otherwise in accordance with Section 4.2(b) and 4.2(c) below.

               (e) Any true-up payment required to be made by the Buyer Parties pursuant to Section 3.2(c) is referred to as the “Final Buyer Payment.” If the Buyer Parties are required to make the Final Buyer Payment, then the Buyer Parties shall promptly (but in any event within five Business Days) pay or cause to be paid an amount equal to the Final Buyer Payment to the Holders in accordance with their respective Pro Rata Shares, by wire transfer of immediately available funds in accordance with the wire transfer instructions set forth on the Merger Consideration Schedule.

          3.3 Adjustment to Merger Consideration. All amounts to be paid under this Article III shall be deemed to be adjustments to the Merger Consideration, except as otherwise required by applicable Law.

ARTICLE IV
ESCROW

          4.1 Escrow Deposit. Subject to the terms and conditions of this Agreement, at the Closing, as provided in Section 2.2, the Buyer Parties shall deposit the Escrow Shares and the Escrow Cash Deposit with the Escrow Agent to be to be held, invested, safeguarded and released by the Escrow Agent in accordance with the terms of the Escrow Agreement and this Agreement. The Parties agree that all Escrow Shares shall be treated as the property of the Accredited Holder in whose name such Escrow Shares were issued at the Closing pursuant to Section 2.2(b)(i)(B) and Section 2.2(b)(iv) (as applicable) for all federal and state income tax purposes unless and until disbursed in accordance with this Agreement and the Escrow Agreement. The Parties agree that all Escrow Cash shall be treated in accordance with Section 3.11 of the Escrow Agreement for all federal and state income tax purposes.

          4.2 Releases.

               (a) The Escrow Agreement will provide that releases of any of the Escrow Funds shall be made only in accordance with written instructions that are jointly signed by the Agent and the Buyer Parties, which instructions shall be in a form that complies with the requirements of the Escrow Agreement (a “Joint Instruction Letter”) or pursuant to an award, judgment, decision or order rendered pursuant to Section 13.4 and/or the Escrow Agreement specifying the number of Escrow Shares or the amount of Escrow Cash to be released from the Escrow Account and the Person or Persons to whom such Escrow Shares or Escrow Cash shall be released.

               (b) In the event that an Accredited Holder or Accredited Holders become obligated finally to (i) the Buyer Parties under Section 3.2(d) in respect of any portion of a Final Holders Payment or (ii) any Buyer Indemnified Party under the terms of Article XII in respect of any indemnification obligation and, subject to the limitations on the Accredited Holders’ liability under Article XII and elsewhere in this Agreement, at such time that there are any remaining Escrow Shares in the Escrow Account, then the Agent and Buyer Parties shall execute and deliver a Joint Instruction Letter to the Escrow Agent directing the Escrow Agent to release to the Buyer Parties or such Buyer Indemnified Party, as applicable, a number of Escrow Shares (to the extent Escrow Shares then remain in the Escrow Account that are sufficient to satisfy such obligation) determined by dividing (1) the amount required to satisfy such obligation by (2) the Market Price as of the date such Buyer Indemnified Party was finally determined to be entitled to indemnification with respect to the relevant Claim(s). Subject to Section 12.6, any such release of Escrow Shares from the Escrow Account shall be allocated against the Accredited Holders in proportion to each Accredited Holder’s Accredited Pro Rata Share of the Escrow Shares, except for any such release in respect of any indemnification obligation that relates to the breach of any representation, warranty or covenant made by any particular Accredited Holder in this Agreement, in which case such release shall be allocated solely against such Accredited Holder’s Accredited Pro Rata Share of the Escrow Shares.

               (c) In the event that a Non-Accredited Holder or Non-Accredited Holders become obligated finally to (i) the Buyer Parties under Section 3.2(d) in respect of any portion of a Final Holders Payment or (ii) any Buyer Indemnified Party under the terms of Article XII in respect of any indemnification obligation and, subject to the limitations on the Non-Accredited Holders’ liability under Article XII and elsewhere in this Agreement, at such time that there is any remaining Escrow Cash in the Escrow Account, then the Agent and Buyer Parties shall execute and deliver a Joint Instruction Letter to the Escrow Agent directing the Escrow Agent to release (to the extent Escrow Cash then remains in the Escrow Account that is sufficient to satisfy such obligation) the cash amount required to satisfy such obligation. Subject to Section 12.6, any such release of Escrow Cash from the Escrow Account shall be allocated against the Non-Accredited Holders in proportion to each Non-Accredited Holder’s Non-Accredited Pro Rata Share of the Escrow Cash, except for any such release in respect of any indemnification obligation that relates to the breach of any representation, warranty or covenant made by any particular Non-Accredited Holder in this Agreement, in which case such release shall be allocated solely against such Non-Accredited Holder’s Non-Accredited Pro Rata Share of the Escrow Cash.

               (d) On the date that is 15 months after the Closing Date, the Agent and the Buyer Parties shall execute and deliver to the Escrow Agent a Joint Instruction Letter instructing the Escrow Agent to release to the Holders all of the Escrow Funds then held in the Escrow Account (except for any Escrow Funds then in the Escrow Account which the Escrow Agent has been validly instructed to release to any Buyer Indemnified Party in accordance with the Escrow Agreement but has not actually released as of such date) less (i) a number of Escrow Shares (valued at the Market Price of such Escrow Shares as of the date that is 15 months after the Closing Date) and (ii) an amount of Escrow Cash, with an aggregate value equal to the amount set forth in any and all Claim Notices submitted in good faith by any Buyer Indemnified Party prior to such date in accordance with Article XII (so long as the facts

or circumstances alleged to give rise to the claim for indemnification underlying such Claim Notice have been specified in reasonable detail) that remain pending as of such date. Escrow Funds so released shall be distributed to the Holders in accordance with Section 4.2(f).

               (e) Following resolution from time to time of any Claim underlying any Claim Notice for which a reserve of a portion of the Escrow Funds was established pursuant to Section 4.2(d), the Agent and the Buyer Parties shall execute and deliver to the Escrow Agent a Joint Instruction Letter instructing the Escrow Agent to release from the Escrow Account to a Buyer Indemnified Party: (i) a number of Escrow Shares (valued at the Market Price of such Escrow Shares as of the date of the final resolution of such Claim) plus (ii) an amount of Escrow Cash, with an aggregate value equal to such portion of the reserve amount as is appropriate for the resolution of such Claim. During the pendency of a Claim for which such a reserve was established, the Agent and the Buyer Parties shall evaluate the amount of such reserve from time to time as the circumstances of such Claim warrant, and, to the extent the Agent and the Buyer Parties agree (each acting reasonably in relation thereto) that such reserve is then greater than the amount that is reasonably expected to be paid in respect of such Claim, Escrow Funds in an amount equal to such excess shall be released to the Holders and distributed in accordance with Section 4.2(f). Following resolution of all such Claims for which such a reserve was established and the release of Escrow Funds to a Buyer Indemnified Party, if any, pursuant to the two preceding sentences, any Escrow Funds remaining in the Escrow Account that were reserved pending resolution of such Claims (except for any Escrow Funds then in the Escrow Account which the Escrow Agent has been validly instructed to release to any Buyer Indemnified Party in accordance with the Escrow Agreement but has not actually released as of such date) shall be released to the Holders and distributed in accordance with Section 4.2(f).

               (f) Escrow Funds released to the Holders pursuant to Section 4.2(d) or Section 4.2(e) shall be distributed as follows:

                         (i) any Escrow Shares to be released to the Holders shall be released solely to the Accredited Holders in proportion to each Accredited Holder’s Accredited Pro Rata Share of the Escrow Shares and shall give effect to any previous releases of Escrow Shares pursuant to Section 4.2(b) that were allocated to any particular Accredited Holder as contemplated in Section 4.2(b); and

                         (ii) any Escrow Cash to be released to the Holders shall be released solely to the Non-Accredited Holders in proportion to each Non-Accredited Holder’s Non-Accredited Pro Rata Share of the Escrow Cash and shall give effect to any previous releases of Escrow Cash pursuant to Section 4.2(c) that were allocated to any particular Non-Accredited Holder as contemplated in Section 4.2(c).

               (g) If Parent distributes a dividend (whether of cash or shares of Parent Common Stock or other Interests) in respect of any Escrow Share during the period when such Escrow Share is held in the Escrow Account that would otherwise be distributable to the Accredited Holder in whose name such Escrow Share has been issued and for whose account such Escrow Share is being held in the Escrow Account, then Parent shall issue such shares of Parent Common Stock or other Interests to such Accredited Holder in accordance with the

terms of this Section 4.2(g) and shall deliver such cash, shares of Parent Common Stock or other Interests to the Escrow Agent to be deposited in the Escrow Account to be held for the account of such Accredited Holder. Such cash, shares of Parent Common Stock or other Interests shall be treated in all respects as Escrow Funds hereunder.

               (h) The applicable Accredited Holders in whose name any Escrow Shares have been issued shall have the exclusive right to exercise all voting rights pertaining to such Escrow Shares held in the Escrow Account for the account of such Accredited Holder unless and until such Escrow Shares are distributed from the Escrow Account to a Person other than such Accredited Holder.

               (i) In the event of a conflict between the Escrow Agreement and this Agreement, this Agreement shall govern. In the event that any Party receives a release of any Escrow Funds pursuant to the Escrow Agreement to which it is not entitled pursuant to the terms of this Agreement, such Party shall (i) if another party is entitled to such Escrow Funds at that time, transfer such Escrow Funds to such other party, or (ii) if no other party is entitled to such Escrow Funds at that time, deposit such Escrow Funds with the Escrow Agent to be held and released pursuant to the Escrow Agreement.

               (j) If either the Agent or any Buyer Party shall fail to timely execute and deliver a Joint Instruction Letter when required under this Agreement, the Agent or the Buyer Parties, as applicable, shall be entitled to seek an order, judgment or decision (in accordance with Section 13.4) that will enable the Escrow Agent to release to the applicable Person or Persons the Escrow Shares to which they are entitled under this Agreement and to seek to recover Losses from the Agent or the Buyer Parties, as applicable, as a result of such failure to comply with this Agreement.

               (k) Notwithstanding anything to the contrary in this Article IV, if any share certificate representing Escrow Shares is deposited with the Escrow Agent on behalf of any Accredited Holder and such share certificate represents more than the number of Escrow Shares that are to be released and disbursed to any Person in accordance with this Article IV and the Escrow Agreement, then the Buyer Parties and the Agent shall cooperate to: (i) instruct the Escrow Agent to release such share certificate from the Escrow Account; (ii) cancel such share certificate; and (iii) replace such share certificate with (A) a share certificate representing the number of Escrow Shares to be released and disbursed to such Person, which shall be issued in the name of and delivered to such Person (or as may be otherwise directed by such Person and, if such Person is Parent or a Subsidiary of Parent, such Escrow Shares shall be cancelled rather than represented on such replacement share certificate), and (B) a share certificate representing all remaining Escrow Shares that were then or deposit in the Escrow Account on behalf of such Accredited Holder immediately prior to such release and disbursement, which shall be issued in the name of the applicable Accredited Holder on whose behalf such Escrow Shares were deposited in the Escrow Account and shall be delivered to the Escrow Agent to hold in the Escrow Account in accordance with this Agreement and the Escrow Agreement.

          4.3 No Fractional Shares. If any calculation of a number of Escrow Shares under this Article IV does not yield a whole number of Escrow Shares, then the number of Escrow

Shares shall be rounded, up or down, to the nearest whole number of Escrow Shares (with any ¹/2 share being rounded up) for all purposes of this Article IV.

                              (C) no Subject Holder shall solicit from any Person that was a customer of an Acquired Company or prospective customer of an Acquired Company with whom such Subject Holder had any contact, in each case, as of or during the 12 months prior to

the Closing Date, the sale, rental or other provision of goods, services or a combination of goods and services that are the same as or similar to those offered by an Acquired Company; and

                              (D) no Subject Holder shall, directly or indirectly cause, solicit, induce or encourage any Continuing Employee to leave such employment. (for purposes of clarification, any such Employee whose employment with either Acquired Company (or either of the Surviving Entities) terminates without violation of this Section 8.5 may be solicited and hired by any such Subject Holder without restriction under this Section 8.5);

provided, however, that (y) the restrictions contained in this Section 8.5(a) shall not restrict any Subject Holder’s activities on behalf of the Parent or any of its Affiliates and (z) the restrictions contained in paragraphs (A) and (B) of this Section 8.5(a) shall not restrict the acquisition by any Subject Holder of (1) any Interests in Parent or (2) less than 2% of the outstanding capital stock of any other publicly traded company engaged in a Restricted Business.

               (b) The Subject Holders hereby acknowledge and agree that, during the course of their association with the Acquired Companies, they have gained certain confidential and proprietary information and trade secrets of the Acquired Companies and the Business (“Acquired Company Confidential Information”), including information with respect to customers and potential customers, new lines of business and areas of operation, suppliers, pricing, bids, projects, pricing methods, operations, processes, protocols, products, inventions, business practices, finances, compensation paid to employees or other terms of employment, the use or disclosure of which by any Subject Holder would be detrimental to Acquired Companies and the Buyer Parties. Accordingly, for so long as the restrictions set forth in Section 8.5(a) are in place, each Subject Holder shall (i) maintain in confidence and not directly or indirectly use, disseminate, disclose or publish, or use for his benefit or the benefit of any Person other than the Parent and its Affiliates Acquired Company Confidential Information, and (ii) not possess other than in its capacity as an officer or employee of the Parent or its Affiliates or deliver to any Person any document, record, notebook, laptop computer, computer program or similar repository of or containing any such Acquired Company Confidential Information. Notwithstanding the foregoing, (A) Acquired Company Confidential Information shall not include: (x) information that is part of the public domain through no breach by any Subject Holder of this Agreement; or (y) information that is in the possession of third parties through no act or failure to act on the part of any Subject Holder and (B) a Subject Holder may disclose Acquired Company Confidential Information if, in the written opinion of counsel, such disclosure is required in response to a lawful and valid subpoena or other legal process but (x) shall give the Buyer Parties the earliest possible notice thereof, (y) shall, as much in advance of the disclosure date as possible, make available to the Buyer Parties and its counsel the documents and other information sought and (z) shall, at the cost of the Buyer Parties, use commercially reasonable efforts to assist such counsel in resisting or otherwise responding to such process.

               (c) If any Subject Holder breaches, or threatens to commit a breach of, any of the provisions of this Section 8.5, then, notwithstanding anything herein to the contrary, including anything contained in Section 12.3 or Section 12.5, the Buyer Parties or Acquired Companies shall have the right and remedy to have the provisions of this Section 8.5 specifically enforced by any court having jurisdiction, and the Subject Holders hereby consent

that temporary or permanent injunctive relief shall be granted in the event of breach of such provisions, all without the need to post a bond or any other security or to prove actual damage or that money damages would not provide an adequate remedy, and the Subject Holders expressly acknowledge and agree that (i) any such breach or threatened breach would cause immediate and irreparable injury to Buyer Parties and the Acquired Companies for which monetary damages would not provide an adequate remedy, (ii) such Subject Holder will not assert, and hereby does waive forever, the claim or defense that there is an adequate remedy at law for purposes of the Buyer Parties or the Acquired Companies obtaining injunctive relief and (iii) Buyer Parties and the Acquired Companies will suffer irreparable damage if any Subject Holder violates any of the covenants set forth in this Section 8.5. Such injunctive relief shall be in addition to all other remedies available to the Buyer Parties at law and in equity. Additionally, in the event that any Subject Holder violates any covenant set forth in this Section 8.5, then any time period applicable to such violated covenant shall be tolled for the duration of such breach.

               (d) Insofar as the covenants set forth in this Section 8.5 are concerned, the Subject Holders specifically acknowledge and agree as follows: (i) they are the principal equity owners of the Acquired Companies and are receiving a substantial monetary benefit as a result of the sale of the Acquired Companies to Buyer Parties; (ii) the business of the Acquired Companies is highly competitive and the assets of the Acquired Companies, including goodwill, customer and prospective customer contacts, potential revenue and customer lists and Acquired Company Confidential Information, are valuable, special and unique as used by the Acquired Companies in the Business and that protection against competition is of critical importance to Buyer Parties; (iii) the covenants contained in this Section 8.5 are reasonable and necessary to protect the Acquired Company Confidential Information and goodwill and the operation and business of the Acquired Companies; (iv) the time duration of the covenants and the geographical area limitations of the covenants contained in this Section 8.5 are reasonable and necessary to protect the Acquired Company Confidential Information and goodwill and the operation and business of the Acquired Companies; and (v) such covenants are not oppressive to the Subject Holders and do not impose a greater restraint on the Subject Holders than is necessary to protect the Acquired Company Confidential Information and goodwill and the operation and business of the Acquired Companies.

               (e) It is the express intention of Buyer Parties, the Acquired Companies and Subject Holders to comply with all Laws which may be applicable to the covenants in this Section 8.5. Consequently, if any court shall determine any covenant contained in this Section 8.5 to be effective in any particular area or jurisdiction only if such covenant is modified to limit its duration or scope, such covenant shall be reformed or modified by the judgment or order of such court to reflect a lawful and enforceable duration or scope. Such covenant automatically shall be deemed to be amended and modified with respect to that particular area or jurisdiction so as to comply with the judgment or order of such court and, as to all other areas and jurisdictions covered by this Agreement, the terms and provisions hereof shall remain in full force and effect as originally written. If any court shall hold any covenants contained in this Section 8.5 to be void or otherwise unenforceable in any particular area or jurisdiction notwithstanding the operation of this provision, such covenant automatically shall be deemed to be amended so as to eliminate therefrom that particular area

or jurisdiction as to which such covenant is so held void or otherwise unenforceable and, as to all other areas and jurisdictions covered by this Agreement, the terms and provisions hereof shall remain in full force and effect as originally written.

          8.6 Use of Name. From and after the Closing Date, none of the Holders nor any of their Affiliates will directly or indirectly use in any manner any trade name, trademark, service ▇▇▇▇ or logo used by the Acquired Companies (other than in the performance of any such Holder’s duties as an employee or otherwise on behalf of the Surviving Entities, the Buyer Parties or any of their respective Affiliates). The Holders shall cause each of Edge Holding and Edge Frac Pumping Services, L.L.C. to change its name so as not to include the word “Edge.”

          8.7 Commercially Reasonable Efforts; Cooperation.

               (a) Subject to the terms and conditions of this Agreement, each of the Parties shall use commercially reasonable efforts to take, or cause to be taken, all actions and to do, or cause to be done, all things necessary or desirable to consummate the transactions contemplated by the Transaction Documents and to ensure the satisfaction of its conditions to Closing set forth in this Agreement. Without limiting the foregoing, each Party shall use commercially reasonable efforts to:

                         (i) obtain all necessary waivers, consents, releases and approvals from other Persons to the consummation of the transactions contemplated by this Agreement;

                         (ii) obtain all consents, approvals and authorizations that are required to be obtained under any Law;

                         (iii) lift or rescind any injunction or restraining order or other order adversely affecting the ability of the Parties to consummate the transactions contemplated by this Agreement;

                         (iv) effect all necessary registrations and filings, including submissions of information requested by Governmental Authorities; and

                         (v) fulfill all conditions applicable to it pursuant to this Agreement.

Notwithstanding anything herein to the contrary, none of the Parties or any of their respective Affiliates shall be required to pay any amounts, or grant any financial accommodation, in connection with obtaining any third party consent, waiver, approval or release.

               (b) The Holders who are not Continuing Employees shall reasonably cooperate with the Buyer Parties after the Closing to ensure the orderly transition of the Acquired Companies and the Business from Holders to Parent and to minimize any disruption to the Business occasioned by the transactions contemplated hereby. After the Closing, upon reasonable written notice, the Holders who are not Continuing Employees shall furnish or cause to be furnished to the Buyer Parties access, during normal business hours, to such information and assistance relating to the Acquired Companies as is reasonably necessary for such orderly transition, including assistance related to Legal Proceedings, claims under any applicable insurance policy for events occurring prior to the Closing Date, financial reporting

and accounting matters, the preparation and filing of any Tax Returns, reports or forms or the defense of any Tax claim or assessment. The Buyer Parties shall provide such Holders with reasonable compensation in consideration for such assistance and shall reimburse such Holders for their out-of-pocket expenses incurred in connection therewith.

               (c) No later than 10 days prior to the Closing Date, the Seller Parties will deliver to Parent for its review the certificates of title to all certificated Acquired Assets in its possession, and the Seller Parties will use commercially reasonable efforts to cooperate with Parent to obtain replacements for any missing, lost or destroyed certificates of title or any certificates of title that are required to be amended in connection with the transactions contemplated hereby.

               (d) Between the Execution Date and the Closing Date, the Seller Parties will use commercially reasonable efforts to obtain the landlord consent required under the real property lease agreement set forth in Schedule 8.7(d), including the payment of any fees required in order to obtain such consent under such lease agreement.

               (e) Between the Execution Date and the Closing Date, the Seller Parties will use commercially reasonable efforts to, at or prior to the Closing, (i) cause to be released any Liens and (ii) terminate any financing statements that have been filed to perfect any such Liens, with respect to the Acquired Companies other than (x) Borrowed Money Debt Liens and (y) Permitted Liens.

          8.8 Insurance Arrangements.

               (a) The Acquired Companies are the primary named insureds with respect to all insurance coverage applicable to the Business for periods prior to Closing. The Parties agree that, following Closing, (i) the Acquired Companies shall cause all insurance coverage provided in relation to the Business pursuant to any such policies (other than any such policies applicable to any Benefit Plans) to be terminated (provided that each Surviving Entity shall retain the benefit of the policies of insurance in relation to liabilities for events occurring prior to Closing) and (ii) Parent shall cause the Acquired Companies to be added as named insureds under each of its existing liability policies of insurance with coverage applicable to the Business that is in effect as of the Closing Date.

               (b) Prior to the Closing, Seller Parties shall use commercially reasonable efforts to cause Buyer Parties and each Surviving Entity to be named as additional insured persons under each liability policy of insurance with coverage applicable to the Business listed on Schedule 6.20, but only with respect to claims arising from events occurring prior to the Closing Date. At the Closing, Seller Parties shall cause to be delivered to Buyer Parties evidence of such additional insured status to the extent obtained. The Buyer Parties shall reimburse the Seller Parties for any out-of-pocket expenses incurred by any Seller Party and shall be responsible for any additional or increased premium payments, in each case in connection therewith.

          8.9 Tax Matters.

               (a) The Agent shall prepare (or cause to be prepared) all federal income Tax Returns required to be filed by or for the Acquired Companies after the Closing Date with respect to any Tax period ending on or before the Closing Date. The Buyer Parties shall prepare (or cause to be prepared) all other Tax Returns required to be filed by or for the Acquired Companies after the Closing Date with respect to any Tax period that ends before or includes the Closing Date (the “Pre-Closing Tax Returns”). Unless otherwise required by Law, the Pre-Closing Tax Returns shall be prepared in a manner consistent with prior practice of the Acquired Companies. The Buyer Parties shall deliver (or cause to be delivered) each Pre-Closing Tax Return to the Agent for its review and comment not later than 30 days prior to the due date of such Pre-Closing Tax Return. The Buyer Parties shall incorporate all reasonable changes requested by the Agent with respect to a Pre-Closing Tax Return at least 10 days prior to the due date of such Pre-Closing Tax Return and shall cause such Pre-Closing Tax Returns to be filed on a timely basis and shall pay all Taxes reflected on such Pre-Closing Tax Returns.

               (b) The Buyer Parties shall not take any action, or allow the Surviving Entities or any of their Affiliates to take any action, in each case other than in the Ordinary Course of Business, that would increase the liability of the Holders or the Acquired Companies for Taxes attributable to a Tax period or portion thereof ending on or before the Closing Date. The Buyer Parties shall pay to the Agent, no later than five Business Days prior to the due date for payment of Taxes due from the Acquired Companies, an amount equal to the excess of (i) the amount accrued as a liability for such Taxes in Net Working Capital shown on the Final Closing Date Balance Sheets over (ii) the amount of such Taxes actually determined or reported to be due as of such date (with the amount of Taxes due with respect to a Straddle Period apportioned between the Holders and the Buyer Parties in accordance with the attribution of liability for Taxes provided in the definition of Seller Taxes) for distribution by the Agent to the Edge Holders with responsibility for the payment of such Taxes, in proportion to their Pro Rata Shares, on or prior to such due date. The Buyer Parties shall promptly pay to the Agent for distribution to the Holders who bore responsibility for such Taxes being refunded, in proportion to their Pro Rata Shares the amount of any refunds received by the Buyer Parties, the Surviving Entities or their respective Subsidiaries, after deducting any costs or Taxes incurred in connection with obtaining and receiving the refund, to the extent such refunds (x) are attributable to a Tax period of either Acquired Company ending on or prior to the Closing Date, or are attributable to the portion of a Straddle Period of an Acquired Company that ends on the Closing Date and (y) exceed the amount accrued therefor as an asset in Net Working Capital shown on the Final Closing Date Balance Sheets (with the amount of Taxes due with respect to a Straddle Period apportioned between the Holders and the Buyer Parties in accordance with the attribution of liability for Taxes provided in the definition of Seller Taxes).

               (c) The Agent and the Buyer Parties shall, and the Buyer Parties shall cause the Surviving Entities and their Subsidiaries to, reasonably cooperate, and shall cause their respective Affiliates and representatives to reasonably cooperate, in preparing and filing all Tax Returns relating to any Tax period beginning on or before the Closing Date, including maintaining and making available to each other, and to any Tax Authority as reasonably

requested, all records in their possession necessary in connection with filing Tax Returns and payment of Taxes of the Acquired Companies and in resolving all disputes and audits with respect to any Tax period beginning on or before the Closing Date relating to Taxes.

               (d) The Buyer Parties hereby agree, from and after the Closing, to pay all transfer, documentary, sales, use, stamp, recording, value added, registration and other similar Taxes and all conveyance fees, recording fees and other similar charges (all including penalties, interest and other charges with respect thereto, collectively “Transfer Taxes”) incurred in connection with the consummation of the transactions contemplated by this Agreement and to protect, defend, indemnify and hold harmless the Holders from and against all Transfer Taxes so incurred; provided, however, that the applicable Holders specified on Schedule 8.15 shall pay all Transfer Taxes incurred with respect to the assets and liabilities being retained by such Holder pursuant to Section 8.15.

               (e) If a Claim with respect to Taxes shall be made by any Governmental Authority, which, if successful, could result in an obligation to make an indemnity payment to a Buyer Indemnified Party pursuant to Article XII (a “Tax Claim”), then notwithstanding any provisions of Article XII to the contrary, the Buyer Parties shall promptly and in any event no more than 15 days following any Buyer Party’s receipt of written notice of such Claim, give written notice to the Agent of such Claim; provided, however, the failure of the Buyer Parties to give such notice shall only relieve the Holders from their indemnification obligations hereunder to the extent they are actually prejudiced by such failure. Within 30 days of receipt of written notice of a Tax Claim, the Agent shall provide written notice to the Buyer Parties of its intent to control the defense of such Tax Claim. Upon providing such notice, the Agent shall be entitled to control all proceedings relating to such Tax Claim and may make all decisions taken in connection with such Tax Claim (including selection of counsel) at its own expense; provided, however, that the Buyer Parties shall be entitled to participate in the defense of any such Tax Claim and shall jointly control the defense of any such Tax Claim the resolution of which would increase the Taxes of the Surviving Entities or their Subsidiaries for any period following the Closing Date. With respect to any Tax Claim that the Agent and the Buyer Parties jointly control, the parties agree not to settle, compromise or otherwise resolve the Tax Claim without the written consent of the Agent and the Buyer Parties, which consent shall not be unreasonably withheld, delayed or conditioned. Absent written notice of the Agent’s intent to control the defense of a Tax Claim as set forth above, or upon written notification to the Buyer Parties that the Agent will decline to control the defense of a Tax Claim, the Buyer Parties shall thereupon be permitted to defend and settle such proceeding. The Agent, the Buyer Parties, the Surviving Entities and their Subsidiaries and each of their respective Affiliates shall reasonably cooperate with each other in contesting or defending against any Tax Claim. Such cooperation shall include the retention and, upon the request of the party or parties controlling proceedings relating to such Tax Claim, the provision to such party or parties of records and information which are reasonably relevant to such Tax Claim, and making employees available on a mutually convenient basis to provide additional information or explanation of any material provided hereunder or to testify at proceedings relating to such Tax Claim.

               (f) Any payments by Buyer Parties under this Section 8.9 shall be deemed to be adjustments to the Merger Consideration, except as otherwise required by applicable Law.

          8.10 Books and Records. The Holders acknowledge and agree that from and after the Closing, the Buyer Parties will be entitled to the originals of all Books and Records. At the Closing, the Holders will promptly deliver to the Buyer Parties such originals or copies of all Books and Records. The Buyer Parties agree that they shall, and shall cause each Surviving Entity to, preserve and keep the Book and Records for a period of six years after the Closing Date. The Buyer Parties shall cooperate in all reasonable respects with the Holders and will make available to the Holders, during normal business hours, the Books and Records which relate to any period that includes or precedes the Closing Date and which are necessary or useful in connection with the preparation or filing of any Tax Return, any Tax Claim, audit or similar investigation or any dispute or litigation, or in order to enable the Holders to comply with their obligations under this Agreement. Following such six year period, the Buyer Parties may retain or destroy such Books and Records in accordance with their record retention policies in effect from time to time; provided, however, that with respect to any Books and Records that are to be destroyed pursuant to such policies, the Buyer Parties will deliver such Books and Records to the Agent if requested by the Agent a reasonable time prior to such destruction.

          8.11 Publicity. The Parties agree that, except to the extent necessary to comply with the requirements of (a) applicable Laws, (b) any listing agreements with securities exchanges or (c) the rules, regulations or orders of any other Governmental Authority, no press release or similar public announcement or communication shall be made or caused to be made concerning the subject matter of this Agreement unless approved in advance by Buyer Parties and the Agent; provided that (i) a press release and Current Report on Form 8-K of Parent announcing the execution and delivery of this Agreement and the transactions contemplated hereby and (ii) any press release or similar public announcement or communication for which advance approval is not required in accordance with the foregoing, the Buyer Parties shall provide to the Agent (with respect to any such release, announcement or communication by the Buyer Parties) and each of the Seller Parties shall provide to the Buyer Parties and the Agent (with respect to any such release, announcement or communication by such Seller Party), to the extent practicable, reasonable notice and a copy of such release, announcement or communication prior to issuing the same.

          8.12 Charter Provisions Regarding Indemnification.

               (a) The Buyer Parties agree that all rights to indemnification for acts or omissions occurring prior to the Closing Date now existing in favor of the current or former managers, directors, officers, members, employees, agents and fiduciaries of either Acquired Company (collectively, the “Acquired Company Indemnitees”) as provided as of the Execution Date in the respective Organizational Documents of the Acquired Companies shall survive the transactions contemplated by this Agreement and shall continue in full force and effect in accordance with their terms for a period of not less than six years from the Closing Date. The Buyer Parties shall not, and shall cause their respective Affiliates (including the Surviving Entities) not to, repeal such arrangements in any manner that would adversely affect the rights of the Acquired Company Indemnitees thereunder. Notwithstanding the foregoing, the Acquired Company Indemnitees shall not be entitled to indemnification pursuant to this Section 8.12 in connection with (i) any matter as to which any Buyer Indemnified Party is entitled to indemnification pursuant to Article XII or (ii) any action, claim or dispute between or among the Holders.

               (b) In the event Parent or either Surviving Entity or any of their respective successors or assigns (i) consolidates with or merges into any other Person and shall not be the continuing or surviving corporation or entity in such consolidation or merger or (ii) transfers all or substantially all of its properties and assets to any Person, then, and in either such case, proper provision shall be made so that the successors and assigns of Parent or such continuing or surviving corporation or entity or such transferee, as the case may be, shall assume all of the obligations set forth in this Section 8.12.

               (c) The obligations of the Buyer Parties under this Section 8.12 shall not be terminated or modified in such a manner as to adversely affect any Acquired Company Indemnitee to whom this Section 8.12 applies without the consent of such Acquired Company Indemnitee so adversely affected.

          8.13 No Shop. Prior to the termination of this Agreement, the Holders shall not, and shall not permit either of the Acquired Companies or their Affiliates, directors, officers, employees, investment bankers, financial advisors, representatives or agents to, directly or indirectly, (a) discuss, encourage, negotiate, undertake, initiate, authorize, recommend, propose or enter into, any business combination transaction, whether by way of merger, consolidation, business combination, purchase or disposition of assets or equity interests of the Acquired Companies or otherwise, other than the transactions contemplated by this Agreement (an “Acquisition Transaction”), (b) facilitate, encourage, solicit or initiate discussions, negotiations or submissions of proposals or offers in respect of an Acquisition Transaction, (c) furnish or cause to be furnished, to any Person, any information concerning the business, operations, properties or assets of the Acquired Companies in connection with an Acquisition Transaction, or (d) otherwise cooperate in any way with, or assist or participate in, facilitate or encourage, any effort or attempt by any other Person to do or seek any of the foregoing. Commencing on the Execution Date, the Holders shall, and shall cause the Acquired Companies and their Affiliates, directors, officers, employees, investment bankers, financial advisors, representatives and agents to, (i) immediately cease and cause to be terminated any existing discussions or negotiations with any Persons (other than the Buyer Parties) conducted heretofore with respect to any Acquisition Transaction, (ii) except to the extent prohibited by a confidentiality obligation owed to a Person as of May 17, 2011, notify the Buyer Parties orally and in writing promptly (but in no event later than two Business Days) after receipt of any proposal or offer from any Person other than the Buyer Parties to effect an Acquisition Transaction or any request for non-public information relating to the Acquired Companies or for access to the properties, books or records of the Acquired Companies by any Person other than the Buyer Parties (such notice shall indicate the material terms of any such proposal or offer, or modification or amendment to such proposal or offer) and (iii) to the extent not previously requested, request the return or destruction of any confidential written or electronic materials provided to any Person in connection with a contemplated or potential Acquisition Transaction.

          8.14 Release of Credit Support Obligations.

               (a) The Buyer Parties (i) recognize that certain Holders, directors, officers, partners, members, equityholders or employees of the Acquired Companies have provided credit support to one or both of the Acquired Companies pursuant to certain guarantees, letters of credit, bonds or other sureties and credit assurances of such Holders, directors, officers,

partners, members, equityholders or employees for the benefit of either or both Acquired Companies (collectively, the “Credit Support Obligations”), which obligations that, as of the Execution Date, are anticipated to survive the Closing are listed on Schedule 8.14 and (ii) acknowledge that the Agent may supplement Schedule 8.14 from time to time prior to the Closing to include any additional Credit Support Obligations entered into in accordance with Section 8.1(e).

               (b) The Buyer Parties shall, or shall cause their Affiliates to, execute and deliver to the appropriate lenders or other obligees (the “Credit Support Beneficiaries”) under any Credit Support Obligation, such replacement guarantees, letters of credit, surety bonds or other sureties, assumption agreements, other agreements and other documents, and supply any credit support as required by each Credit Support Beneficiary, in order to effect, effective as of the Closing Date, Parent’s or its Affiliates’ assumption of all obligations relating to each Credit Support Obligation and the full and unconditional release of all Holders and directors, officers, partners, members, equityholders and employees of either Acquired Company from such Credit Support Obligations.

               (c) If the Buyer Parties are not successful, for any reason, in obtaining the full and unconditional release of all Holders and directors, officers, partners, members, equityholders and employees of either Acquired Company from any Credit Support Obligation by the Closing Date (each such Credit Support Obligation, until such time as such Credit Support Obligation is released in accordance with Section 8.14(b), a “Continuing Credit Support Obligation”), then:

                         (i) the Buyer Parties shall continue to use their commercially reasonable efforts to obtain promptly the full and unconditional release of all such Persons from each Continuing Credit Support Obligation until such release is obtained; and

                         (ii) the Buyer Parties shall indemnify each such Person for any demand or draw upon, or withdrawal from, any Continuing Credit Support Obligation or any cash or other collateral posted by any such Person in connection with or in the place of any such Continuing Credit Support Obligation and for the carrying costs of any cash collateral not replaced by the Buyer Parties, the fronting fee costs, and any other out-of-pocket third-party costs and expenses resulting from each such Continuing Credit Support Obligation.

As soon as reasonably practicable following the Closing but in any event no later than 20 days after the Closing Date, the Buyer Parties shall cause each Surviving Entity to deliver to the applicable Holder or Employee a check in an amount equal to the portion of the Change of Control Payments set forth opposite such Holder’s or Employee’s name on Schedule 2.2(a)(vii), net of any applicable deduction or withholding for or on account of any Tax required to be deducted or withheld therefrom, the amount of such deduction or withholding being set forth next to the name of the recipient of each Change of Control Payment on Schedule 2.2(a)(vii).

No Holder Indemnifying Party will have any liability under Section 12.1(a)(i), Section 12.1(b)(i) or Section 12.1(c) until the Buyer Indemnified Parties have suffered Losses in excess of an aggregate amount equal to $2,000,000 arising from Claims under such sections, and then, subject to Section 12.3(b), the recoverable Losses under this Article XII for such Claims shall be equal to the entire amount of any such Losses from the first dollar (including the first $2,000,000); provided that the limitations set forth in this Section 12.3(a) shall not apply to Losses arising from any breach or inaccuracy of the representations and warranties set forth in Article V or Sections 6.1 (Authority; Enforceability), 6.2 (Consents; Absence of Conflicts), 6.3 (Organization; Existence and Good Standing), 6.5 (Capitalization; Subsidiaries), 6.13 (Brokers’ Fees) or 6.15 (Taxes) (collectively, the “Fundamental Seller Representations”). No Buyer Indemnifying Party will have any liability under Section 12.2(a) until the Holder Indemnified Parties have suffered Losses in excess of an aggregate amount equal to $2,000,000 arising from Claims under such section, and then, subject to Section 12.3(b), the recoverable Losses under this Article XII for such Claims shall be equal to the entire amount of any such Losses from the first dollar (including the first $2,000,000); provided that the limitations set forth in this Section 12.3(a) shall not apply to Losses arising from any breach or inaccuracy of the representations and warranties set forth in Sections 7.1 (Authority; Enforceability), 7.2 (Consents, Absence of Conflicts), 7.3 (Organization; Existence and Good Standing), 7.4 (Parent Capitalization), 7.5 (Representation as to Parent Share Consideration) or 7.9 (Brokers’ Fees) (collectively, the “Fundamental Buyer Representations”).

               (b) Caps.

                         (i) Seller Party Caps.

                              (A) the aggregate liability of the Holders under this Agreement shall not exceed $30,000,000 (the “Aggregate Cap”); and

                              (B) each Holder’s aggregate liability under this Agreement shall not exceed an amount equal to such Holder’s Pro Rata Share multiplied by the amount of the Aggregate Cap (the “Individual Cap”);

provided, however, that the limitations set forth in Section 12.3(b)(i)(A)-(B) shall not apply to Losses (i) arising from any inaccuracy in or breach of any Fundamental Seller Representation (as to which the liability of any Holder shall not exceed an amount equal to such Holder’s Pro Rata Share multiplied by the Merger Consideration), (ii) arising under Sections 12.1(a)(ii), 12.1(b)(ii), 12.1(b)(iii), 12.1(b)(iv), 12.1(b)(vi) or 12.1(b)(viii).

                         (ii) Buyer Party Cap. The aggregate liability of the Buyer Parties under this Agreement shall not exceed the amount of the Aggregate Cap; provided, however, that

the limitations set forth in this Section 12.3(b)(ii) shall not apply to Losses (i) arising from any inaccuracy in or breach of any Fundamental Buyer Representation or (ii) arising under Section 12.2(b); provided further, however, that in no event shall the Buyer Parties’ aggregate liability under this Agreement exceed an amount equal to the Merger Consideration.

               (c) Survival; Claims Period. All representations and warranties of the Parties contained in this Agreement shall survive the Closing until the date that is 15 months after the Closing Date; provided that such 15-month survival period shall not apply to: (i) any representation or warranty set forth in Section 6.19 (Environmental Matters), which representations and warranties shall survive the Closing until the third anniversary of the Closing Date; (ii) any representation or warranty set forth in the Fundamental Seller Representations (excluding Section 6.15 (Taxes), which is the subject of clause (iii) below) or the Fundamental Buyer Representations, which representations and warranties shall survive the Closing indefinitely; and (iii) any representation or warranty set forth in Section 6.15 (Taxes), 6.17 (Employees; Employee Matters), 6.18 (Employee Benefit Matters) or 7.6 (Parent SEC Filings), which representations and warranties shall survive the Closing until the date that is three months after the expiration of the applicable statute of limitation (the date, if any, on which a representation or warranty contained in this Agreement so expires, the “Expiration Date”). All covenants contained in this Agreement that by their terms are to be performed at or prior to the Closing shall terminate at the Closing, and all covenants contained in this Agreement that by their terms are to be performed after the Closing shall survive the Closing until performed in accordance with their terms. No Indemnifying Party shall have any liability for indemnification claims made under this Article XII with respect to any breach of any representation or warranty unless a Claim Notice in respect of such claim is timely given in accordance with this Agreement on or prior to the applicable Expiration Date. If a Claim Notice has been timely given in accordance with this Agreement on or prior to the applicable Expiration Date, then the applicable representation or warranty shall survive as to such Claim until such Claim has been finally resolved.

               (d) Merger Consideration Adjustment. The procedures set forth in Article III and the dispute resolution procedures set forth therein shall provide the sole and exclusive remedies for claims relating to the calculation of Final Net Working Capital and the Final CapEx Reimbursement Amount, and the Indemnified Parties shall not have recourse under this Article XII for breaches of representations and warranties contained in this Agreement to the extent that the Losses that are attributable to such breach are taken into account in determining the Final Net Working Capital or the Final CapEx Reimbursement Amount pursuant to Article III.

               (e) Mitigation. The Parties agree that no Indemnified Party shall have any recourse under this Article XII for any Losses that such Indemnified Party would not have suffered had such Indemnified Party exercised reasonable commercial efforts to mitigate such Losses within a reasonable amount of time following the discovery by such Indemnified Party of the fact, event or circumstance giving rise to such Losses (and for a Buyer Indemnified Party that is not a natural Person, the bringing to the attention of a responsible officer thereof of such fact, event or circumstance).

               (f) Disregard of Materiality Qualifications. For purposes of determining whether any Indemnified Party is entitled to indemnification for any Losses under this Article XII arising from any breach of any representation or warranty set forth in this Agreement (other than the representations and warranties set forth in Section 6.6(b) and Section 7.7(a)) and in calculating the amount of such Losses, the Parties shall disregard (i) any requirement in any such representation or warranty that an event or fact be material, have a Material Adverse Effect, have a Parent Material Adverse Effect, or otherwise be subject to a similar qualification as to materiality, material adverse effect or words of similar import and (ii) any other references to materiality, material adverse effect or words of similar import in any such representation or warranty.

               (g) Recovery. In the event that any Losses are suffered by any one or more Indemnified Parties for which any such Indemnified Party is entitled to indemnification under this Article XII and any such Indemnified Party is indemnified by an Indemnifying Party with respect to such Losses, then such Losses shall be deemed to have been fully satisfied and shall no longer exist and, therefore, any further recovery by such Indemnified Party or any other Indemnified Party from any Indemnifying Party for such same Losses would constitute an unintended “double” recovery and shall be prohibited under this Agreement. Notwithstanding the foregoing, an Indemnified Party shall be entitled to seek recovery under such provisions of this Article XII that maximize its recovery (e.g., if particular Losses would be subject to the Aggregate Cap if a claim were made under one provision but would not be subject to the Aggregate Cap if made under another provision, then the Indemnified Party may seek recovery under the provision that is not subject to the Aggregate Cap).

               (h) Knowledge. The Indemnified Parties’ rights under this Agreement or otherwise shall not be diminished by any investigation performed or knowledge acquired or capable of being acquired, whether before or after the Execution Date, regarding the accuracy or inaccuracy of any representation or warranty or the performance or non-performance of any covenant.

          12.4 Calculation of Losses.

               (a) The amount of any Losses for which any Indemnified Party is finally determined to be entitled to indemnification under this Article XII shall be reduced by (i) any insurance proceeds actually received by the Buyer Indemnified Parties or Holder Indemnified Parties (as applicable) with respect to such Losses (net of reasonable out-of-pocket expenses incurred in obtaining such insurance proceeds and the amount of any retrospective or other current increase in premium that is directly attributable to the payment of such insurance proceeds), and (ii) indemnification or reimbursement payments actually received by the Buyer Indemnified Parties or Holder Indemnified Parties (as applicable) from third parties with respect to such Losses (net of reasonable out-of-pocket expenses incurred in obtaining such payments).

               (b) Notwithstanding anything to the contrary in this Agreement, if any matter giving rise to a claim of Losses by any Buyer Indemnified Party pursuant to this Article XII is reasonably likely to be covered by any insurance policy of any Party or its Affiliates, then the Parties shall cooperate with one another and use commercially reasonable efforts to obtain

reimbursement for such Losses under such insurance policy; provided, however, that if any insurance proceeds are thereafter received with respect to Losses that have been satisfied:

                         (i) by a release of any of the Escrow Shares, then such Indemnified Party shall promptly (A) until such time as the Escrow Account has been terminated in accordance with Article IV and the Escrow Agreement, deliver to the Escrow Agent to be deposited in the Escrow Account cash in an amount equal to the amount of such insurance proceeds, net of reasonable out-of-pockets expenses incurred in obtaining such insurance proceeds, and such cash shall be treated in all respects thereafter for purposes of this Agreement as if same were Escrow Shares deposited for the credit of the applicable Accredited Holders and (B) from and after the termination of the Escrow Account in accordance with Article IV and the Escrow Agreement, deliver to the Agent (for distribution to the Accredited Holders) cash in an amount equal to the amount of such insurance proceeds, net of such expenses;

                         (ii) by a release of any of the Escrow Cash, then such Indemnified Party shall promptly (A) until such time as the Escrow Account has been terminated in accordance with Article IV and the Escrow Agreement, deliver to the Escrow Agent to be deposited in the Escrow Account cash in an amount equal to the amount of such insurance proceeds, net of reasonable out-of-pockets expenses incurred in obtaining such insurance proceeds, and such cash shall be treated in all respects as Escrow Cash thereafter and (B) from and after the termination of the Escrow Account in accordance with Article IV and the Escrow Agreement, deliver to the Agent (for distribution to the Non-Accredited Holders) cash in an amount equal to the amount of such insurance proceeds, net of such expenses; and

                         (iii) otherwise directly by a Holder by a payment made by such Holder, then such Indemnified Party shall promptly reimburse each Holder for the amount of any such payment made directly by such Holder (up to the amount of the insurance proceeds received by such Indemnified Party, net of reasonable out-of-pockets expenses incurred in obtaining such insurance proceeds);

provided further that the amount of cash to be deposited or paid pursuant to this Section 12.4(b) shall not exceed the amount of insurance proceeds received, net of reasonable out-of-pocket expenses incurred in obtaining such proceeds, and shall be deposited or paid pursuant to clauses (i) through (iii) in the same relative proportions such amount was disbursed or paid to the Buyer Indemnified Parties in satisfaction of such Losses pursuant to Section 12.6.

               (c) If no such insurance proceeds are received by a Buyer Indemnified Party after making the commercially reasonable efforts contemplated by Section 12.4(b), and such Buyer Indemnified Party recovers any such Losses from an Indemnifying Party or Parties, then such Buyer Indemnified Party shall concurrently therewith execute and deliver to the Indemnifying Party or Parties such agreements, documents and instruments as may be reasonably necessary to assign to such Indemnifying Party or Parties its claim under such insurance policy with respect to such Losses and shall reasonably cooperate with such Indemnifying Party or Parties in its efforts to collect insurance proceeds thereunder.

          12.5 Exclusive Remedy; Waiver.

               (a) NOTWITHSTANDING ANYTHING TO THE CONTRARY IN THIS AGREEMENT, IF THE CLOSING OCCURS AND EXCEPT (I) AS PROVIDED IN THIS ARTICLE XII AND IN SECTION 8.5 AND SECTION 8.12 OR (II) IN THE CASE OF CRIMINAL ACTIVITY OR FRAUD ON THE PART OF ANY PARTY, NO INDEMNIFYING PARTY OR INDEMNIFIED PARTY SHALL HAVE ANY LIABILITY, AND NO INDEMNIFIED PARTY SHALL MAKE ANY CLAIM, FOR ANY LOSS (AND THE PARTIES HEREBY WAIVE ANY RIGHT OF CONTRIBUTION AGAINST EACH OTHER, THE INDEMNIFYING PARTIES AND THE INDEMNIFIED PARTIES AND THEIR RESPECTIVE AFFILIATES), UNDER, ARISING OUT OF OR RELATING TO THIS AGREEMENT OR ANY CERTIFICATE DELIVERED PURSUANT TO THIS AGREEMENT, WHETHER BASED IN CONTRACT, TORT, STRICT LIABILITY, OTHER LAWS OR OTHERWISE.

               (b) NOTWITHSTANDING ANYTHING TO THE CONTRARY IN THIS AGREEMENT, NO INDEMNIFYING PARTY OR INDEMNIFIED PARTY SHALL BE LIABLE FOR EXEMPLARY, PUNITIVE, SPECIAL, INDIRECT, CONSEQUENTIAL (OTHER THAN DIMINUTION IN VALUE), REMOTE OR SPECULATIVE DAMAGES, WHETHER BASED IN CONTRACT, TORT, STRICT LIABILITY, OTHER LAW OR OTHERWISE; PROVIDED, HOWEVER, THAT THIS SECTION 12.5(b) SHALL NOT LIMIT A PARTY’S RIGHT TO RECOVERY UNDER THIS ARTICLE XII FOR ANY SUCH DAMAGES TO THE EXTENT SUCH PARTY IS REQUIRED TO PAY SUCH DAMAGES TO A THIRD PARTY IN CONNECTION WITH A MATTER FOR WHICH SUCH PARTY IS OTHERWISE ENTITLED TO INDEMNIFICATION UNDER THIS ARTICLE XII.

               (c) NOTWITHSTANDING ANYTHING IN THIS AGREEMENT TO THE CONTRARY, NO REPRESENTATIVE OR AFFILIATE OF ANY PARTY (OR ANY REPRESENTATIVE OF ANY SUCH AFFILIATE) IN SUCH CAPACITY SHALL HAVE ANY PERSONAL LIABILITY TO ANY PARTY AS A RESULT OF THE BREACH OF ANY REPRESENTATION, WARRANTY, COVENANT, AGREEMENT OR OBLIGATION IN THIS AGREEMENT OR ANY CERTIFICATE DELIVERED PURSUANT TO THIS AGREEMENT. EACH PARTY HEREBY WAIVES, AND SHALL CAUSE EACH OF ITS AFFILIATES TO WAIVE, ANY CLAIMS OR OTHER METHOD OF RECOVERY, WHETHER BASED IN CONTRACT, TORT OR STRICT LIABILITY, OR UNDER APPLICABLE LAW, AGAINST ANY SUCH REPRESENTATIVE OR AFFILIATE RELATING TO THE TRANSACTIONS CONTEMPLATED BY THE TRANSACTION DOCUMENTS.

               (d) HOLDERS HEREBY WAIVE, AND AGREE NOT TO ASSERT, ANY AND ALL RIGHTS, WHETHER BY CONTRACT, AT LAW, IN EQUITY OR OTHERWISE, HOLDERS MAY HAVE TO MAKE A CLAIM AGAINST OR OTHERWISE DEMAND OR RECEIVE PAYMENT FROM EITHER OF THE ACQUIRED COMPANIES ARISING OUT OF OR WITH RESPECT TO, THE INACCURACY OR BREACH OF ANY REPRESENTATION OR WARRANTY OF ANY HOLDER OR EITHER ACQUIRED COMPANY SET FORTH IN THIS AGREEMENT OR THE

BREACH BY ANY HOLDER OR EITHER ACQUIRED COMPANY PRIOR TO THE CLOSING DATE OF ANY COVENANT OR AGREEMENT SET FORTH IN THIS AGREEMENT.

               (e) EFFECTIVE AS OF THE CLOSING, HOLDERS DO HEREBY FOREVER RELEASE AND DISCHARGE EACH OF THE ACQUIRED COMPANIES FROM ANY AND ALL CLAIMS, DEMANDS, CAUSES OF ACTION, LOSSES OR LIABILITIES OF ANY KIND OR NATURE WHATSOEVER WHICH RELATE TO OR ARISE OUT OF ANY DEALINGS, RELATIONSHIPS OR TRANSACTIONS, PRIOR TO THE CLOSING DATE, BY AND BETWEEN HOLDERS AND EACH OF THE ACQUIRED COMPANIES, WHETHER ARISING UNDER CONTRACT, AT LAW OR IN EQUITY, AGAINST EITHER OF THE ACQUIRED COMPANIES THAT THEY EVER HAD, NOW HAVE OR HEREAFTER CAN, SHALL OR MAY HAVE, WHETHER OR NOT NOW KNOWN, OTHER THAN (I) RIGHTS TO INDEMNIFICATION IN RESPECT OF CLAIMS OR LOSSES AS DESCRIBED IN OR ARISING UNDER SECTION 8.12, (II) RIGHTS UNDER THIS AGREEMENT AND THE OTHER TRANSACTION DOCUMENTS AND (III) UNPAID COMPENSATION OR UNPAID BENEFITS, IN EACH CASE, ACCRUED IN THE ORDINARY COURSE OF BUSINESS, BUT ONLY TO THE EXTENT SUCH COMPENSATION OR BENEFITS RELATE TO THE 45 DAY PERIOD PRIOR TO THE CLOSING DATE OR WERE PROPERLY ACCRUED DURING SUCH PERIOD. EXCEPT AS EXPRESSLY LIMITED IN THIS SECTION 12.5(E), HOLDERS UNDERSTAND AND AGREE THAT THEY ARE HEREBY EXPRESSLY WAIVING ALL CLAIMS RELATED TO ANY PERIOD PRIOR TO THE CLOSING DATE, EVEN THOSE THEY MAY NOT KNOW OR SUSPECT TO EXIST, WHICH IF KNOWN MAY HAVE AFFECTED THE DECISION TO PROVIDE THIS RELEASE, AND HOLDERS WAIVE ANY RIGHTS UNDER APPLICABLE LAW THAT PROVIDE TO THE CONTRARY.

          12.6 Payment of Indemnification Claims. To the extent it is finally determined that a Holder is required to provide an indemnification payment pursuant to Section 12.7 or Section 12.8, the sole and exclusive method of satisfaction of such payment shall be, and recourse to recover for such indemnification payment shall be limited to the following:

               (a) if such Holder is an Accredited Holder, first the release of a portion of Escrow Shares then deposited in the Escrow Account (up to such Accredited Holder’s Accredited Pro Rata Share of the aggregate number of Escrow Shares deposited in the Escrow Account on the Closing Date); provided that, in no event shall the number of Escrow Shares released from the Escrow Account in respect of indemnification payments so required from such Accredited Holder exceed such Accredited Holder’s Accredited Pro Rata Share of such Escrow Shares; and then, to the extent any amounts remain owing, such amounts shall be payable directly by such Accredited Holder; provided further that, notwithstanding anything in Section 12.3(b)(i)(B) to the contrary, if such Accredited Holder is a ▇▇▇▇▇▇ Holder, any amounts that remain owing in excess of such Accredited Holder’s Accredited Pro Rata Share of such Escrow Shares shall additionally be payable from ▇▇▇▇▇▇’▇ Accredited Pro Rata Share of the Escrow Shares, and, to the extent no Escrow Shares are then held for the account of such Accredited Holder or ▇▇▇▇▇▇ either because all such shares have been released or because the Escrow Account has been terminated, then any amounts that remain owing by such Accredited

Holder shall additionally be payable directly by ▇▇▇▇▇▇ on behalf of such Accredited Holder, and, in any such case, such Accredited Holder shall thereafter reimburse and indemnify ▇▇▇▇▇▇ for any such amounts as are paid by ▇▇▇▇▇▇ on such Accredited Holder’s behalf and for any Losses incurred by ▇▇▇▇▇▇ in connection therewith; and

               (b) If such Holder is a Non-Accredited Holder, first the release of Escrow Cash then deposited in the Escrow Account (up to such Non-Accredited Holder’s Non-Accredited Pro Rata Share of the Escrow Cash deposited in the Escrow Account on the Closing Date); provided that, in no event shall the amount of Escrow Cash released from the Escrow Account in respect of indemnification payments so required from such Non-Accredited Holder exceed such Non-Accredited Holder’s Non-Accredited Pro Rata Share of such Escrow Cash; and then, to the extent any amounts remain owing, such amounts shall be payable directly by such Non-Accredited Holder; provided further that, notwithstanding anything in Section 12.3(b)(i)(B) to the contrary, if such Non-Accredited Holder is a ▇▇▇▇▇▇ Holder, any amounts that remain owing in excess of such Non-Accredited Holder’s Non-Accredited Pro Rata Share of such Escrow Cash, or, if no Escrow Cash is then held for the account of such Non-Accredited Holder either because all such cash has been released or because the Escrow Account has been terminated, then any amounts that remain owing by such Non-Accredited Holder shall additionally be payable directly by ▇▇▇▇▇▇ on behalf of such Non-Accredited Holder, and, in any such case, such Non-Accredited Holder shall thereafter reimburse and indemnify ▇▇▇▇▇▇ for any such amounts as are paid by ▇▇▇▇▇▇ on such Non-Accredited Holder’s behalf and for any Losses incurred by ▇▇▇▇▇▇ in connection therewith.

               (c) For the avoidance of doubt, ▇▇▇▇▇▇ shall be jointly and severally liable with any ▇▇▇▇▇▇ Holder for all purposes of this Article XII as to indemnification claims involving payments or potential payments by ▇▇▇▇▇▇ on behalf of a ▇▇▇▇▇▇ Holder pursuant to this Section 12.6, and a Buyer Indemnified Party may proceed directly against ▇▇▇▇▇▇ in respect of any such claim without the necessity of first proceeding against such ▇▇▇▇▇▇ Holder (except to the extent such ▇▇▇▇▇▇ Holder has Escrow Shares or Escrow Cash in the Escrow Account, in which case such Buyer Indemnified Party’s indemnity claim shall first be satisfied out of such Escrow Shares or Escrow Cash, as contemplated by clauses (a) and (b) of this Section 12.6).

               (d) If amounts are owed to a Buyer Indemnified Party from the Seller Indemnified Parties and such amounts are to be paid from Escrow Shares or Escrow Cash, the Agent shall promptly execute a Joint Instruction Letter in respect of such amounts and cooperate with such Buyer Indemnified Party in delivering such Joint Instruction Letter to the Escrow Agent. If amounts remain owing to a Buyer Indemnified Party from a Holder or ▇▇▇▇▇▇ pursuant to clauses (a) or (b) of this Section 12.6, the Agent shall, within five Business Days of written request by such Buyer Indemnified Party, prepare and transmit to each Holder from whom amounts are due and, if applicable, ▇▇▇▇▇▇, a written notice demanding payment of such amounts, which amounts shall be payable by such Holder and, if applicable, ▇▇▇▇▇▇, within 10 Business Days of the giving of such notice, in immediately available funds, to an account specified by the Buyer Indemnified Party in such notice.

          12.7 Non-Third-Party Claim Procedures. If any Indemnified Party shall claim indemnification hereunder for any matter (other than a Third-Party Claim), the Indemnified Party

shall promptly give written notice (a “Claim Notice”) to the applicable Indemnifying Party setting forth the basis for such claim and the nature and estimated amount of the claim (to the extent then known by the Indemnified Party), all in reasonable detail. No delay or failure on the part of the Indemnified Party in so notifying the Indemnifying Party shall relieve the Indemnifying Party of any liability or obligation hereunder except to the extent of any damage or liability caused by or arising out of such delay or failure. Within 30 days after delivery of a Claim Notice, the Indemnifying Party shall deliver to the Indemnified Party a response, in which the Indemnifying Party shall either: (i) agree that the Indemnified Party is entitled to receive all of the claimed amount (in which case the response shall be accompanied by a payment by the Indemnifying Party to the Indemnified Party of such amount, by check or by wire transfer; provided that if such amount is to be paid through the release of Escrow Shares or Escrow Cash, the Indemnifying Party and the Indemnified Party shall cause the Agent and the Buyer Parties (as applicable) to deliver to the Escrow Agent, within three Business Days following the delivery of such response, a Joint Instruction Letter instructing the Escrow Agent to pay to Buyer Parties an amount of Escrow Funds equal to such claimed amount), (ii) agree that the Indemnified Party is entitled to receive a portion of the claimed amount (in which case the response shall be accompanied by a payment by the Indemnifying Party to the Indemnified Party of the amount so agreed upon, by check or by wire transfer; provided that if such amount is to be paid through the release of Escrow Shares or Escrow Cash, the Indemnifying Party and the Indemnified Party shall cause the Agent and the Buyer Parties (as applicable) to deliver to the Escrow Agent, within three Business Days following the delivery of the response, a Joint Instruction Letter instructing the Escrow Agent to pay to Buyer Parties an amount of Escrow Funds equal to such agreed upon amount) or (iii) dispute that the Indemnified Party is entitled to receive all of the claimed amount. Acceptance by Buyer Parties of partial payment of any claimed amount shall be without prejudice to Buyer Parties’ right to claim the balance of any such claimed amount.

          12.8 Third-Party Claim Procedures.

               (a) If any Indemnified Party shall claim indemnification hereunder arising from any claim or demand of a third party (a “Third-Party Claim”), the Indemnified Party shall promptly after it receives written notification of such Third-Party Claim, give written notice (a “Third-Party Notice”) to the applicable Indemnifying Party setting forth the basis for such Third-Party Claim and the nature and estimated amount of such Third-Party Claim (to the extent then known by the Indemnified Party) in reasonable detail, together with a copy of the written notification of such Third-Party Claim. No delay or failure on the part of the Indemnified Party in so notifying the Indemnifying Party shall relieve the Indemnifying Party of any liability or obligation hereunder except to the extent of any damage or liability caused by or arising out of such delay or failure. Within 30 days after receiving such Third-Party Notice, the Indemnifying Party, upon notice to the Indemnified Party, may, at its own cost and through counsel of its own choosing, defend any claim or demand set forth in a Third-Party Notice; provided that (i) the Indemnifying Party may only assume control of such defense if (A) it acknowledges in writing to the Indemnified Party that any damages, fines, costs or other liabilities that may be assessed against the Indemnifying Party in connection with such Third-Party Claim constitute Losses for which the Indemnifying Party shall be indemnified pursuant to this Article XII and (B) the damages sought in such Third-Party Claim, taken together with the estimated costs of defense thereof and the amount claimed by the Indemnified Parties with respect to any unresolved claims for indemnification then pending, is not greater than the then remaining obligation of the

Indemnifying Party hereunder (taking into account the limitations on liability described in Section 12.3) and (ii) the Indemnifying Party may not assume control of the defense of any Third-Party Claim involving Taxes (other than Seller Taxes), criminal liability or in which equitable relief is sought against the Indemnified Party, or if an adverse resolution of the Third-Party Claim would, in the reasonable determination of the Indemnified Party, have a material adverse effect on the business, operations or future conduct of the Indemnified Party. If the Indemnifying Party does not, or is not permitted under the terms hereof to, so assume control of the defense of a Third-Party Claim, the Indemnified Party 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 reasonably apprised of the status of such Third-Party Claim and the defense thereof and shall consider in good faith recommendations made by the non-controlling Party with respect thereto. Each of the Indemnified Party and the Indemnifying Party shall, promptly upon the other’s reasonable request therefor, furnish such information as it may have with respect to such Third-Party Claim (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), make documents available for inspection and copying, make employees available for interviews, depositions and trial, and otherwise cooperate with and assist the controlling Party in the defense of such Third-Party Claim, all of the foregoing subject to the receipt of reasonable prior notice and the reimbursement of the reasonable out of pocket expenses of the Indemnified Party by the Indemnifying Party. The reasonable fees and expenses of counsel to the Indemnified Party with respect to a Third-Party Claim shall be considered Losses for purposes of this Agreement if and to the extent (i) the Indemnified Party controls the defense of such Third-Party Claim pursuant to the terms of this Section 12.8(a) or (ii) the Indemnifying Party assumes control of such defense and, in the reasonable view of outside counsel to the Indemnifying Party, there exists a conflict between the interests of the Indemnified Party and the Indemnifying Party or different defenses with respect to such Third-Party Claim are available to the Indemnified Party which are not available to the Indemnifying Party, provided that the Indemnifying Party shall not be liable for the costs and expenses of more than one counsel for all Indemnified Parties in each jurisdiction to which such Third Party Claim relates. Neither the Seller Parties nor the Agent shall agree to any settlement of, or the entry of any judgment arising from, any Third-Party Claim without the prior written consent of Buyer Parties, which shall not be unreasonably withheld, conditioned or delayed; provided that the consent of Buyer Parties shall not be required if the Agent, on behalf of all of the Seller Parties, agrees in writing to pay any amounts payable pursuant to such settlement or judgment and such settlement or judgment includes a complete release of Buyer Parties from further liability, involves only the payment of money damages or amounts in settlement and has no other adverse effect on Buyer Parties. Buyer Parties shall not agree to any settlement of, or the entry of any judgment arising from, any such Third-Party Claim without the prior written consent of the Agent, which shall not be unreasonably withheld, conditioned or delayed. Without limiting the foregoing, the Indemnifying Party will be subrogated to all rights and remedies of the Indemnified Party against the third party making such Third-Party Claim, and the Indemnified Party will reasonably cooperate with and assist the Indemnifying Party in asserting all such rights and remedies against such third party.

               (b) The Parties acknowledge and agree that (i) the ▇▇▇▇ Lawsuit constitutes a Third-Party Claim and (ii) a Claim for indemnification under Section 12.1(b)(iv) with respect to the ▇▇▇▇ Lawsuit shall be deemed to have been made by the Buyer Parties as of the Effective

Time for all purposes under this Article XII. The Parties further acknowledge and agree that the Holders shall assume the defense of the ▇▇▇▇ Lawsuit pursuant to the provisions of Section 12.8(a).

          12.9 Exclusive Representations and Warranties.

               (a) THE BUYER PARTIES ACKNOWLEDGE AND AGREE THAT: (I) THE REPRESENTATIONS AND WARRANTIES SET FORTH IN ARTICLE V AND ARTICLE VI AND IN ANY CERTIFICATES DELIVERED PURSUANT TO THIS AGREEMENT CONSTITUTE THE SOLE AND EXCLUSIVE REPRESENTATIONS AND WARRANTIES OF THE SELLER PARTIES IN CONNECTION WITH THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT AND (II) EXCEPT FOR SUCH REPRESENTATIONS AND WARRANTIES, THERE ARE NO REPRESENTATIONS OR WARRANTIES OF THE SELLER PARTIES REGARDING THE ACQUIRED COMPANIES, THE BUSINESS OR THE ACQUIRED ASSETS.

               (b) THE SELLER PARTIES ACKNOWLEDGE AND AGREE THAT: (I) THE REPRESENTATIONS AND WARRANTIES SET FORTH IN ARTICLE VII AND IN ANY CERTIFICATES DELIVERED PURSUANT TO THIS AGREEMENT CONSTITUTE THE SOLE AND EXCLUSIVE REPRESENTATIONS AND WARRANTIES OF THE BUYER PARTIES IN CONNECTION WITH THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT AND (II) EXCEPT FOR SUCH REPRESENTATIONS AND WARRANTIES, THERE ARE NO REPRESENTATIONS OR WARRANTIES OF THE BUYER PARTIES.

BY EXECUTING AND DELIVERING THIS AGREEMENT, EACH PARTY IRREVOCABLY (I) ACCEPTS GENERALLY AND UNCONDITIONALLY THE EXCLUSIVE JURISDICTION AND VENUE OF SUCH COURTS; (II) WAIVES ANY DEFENSE OF FORUM NON CONVENIENS; AND (III) AGREES THAT SERVICE OF ALL PROCESS IN ANY SUCH PROCEEDING IN ANY SUCH COURT MAY BE MADE BY NOTICE TO THE APPLICABLE PARTY AT ITS ADDRESS PROVIDED IN ACCORDANCE WITH SECTION 13.2, IS SUFFICIENT TO CONFER PERSONAL JURISDICTION OVER THE APPLICABLE PARTY IN ANY SUCH PROCEEDING IN ANY SUCH COURT, AND OTHERWISE CONSTITUTES EFFECTIVE AND BINDING SERVICE IN EVERY RESPECT. NOTHING CONTAINED IN THIS SECTION 13.4 SHALL PREVENT ANY PARTY FROM SEEKING INJUNCTIVE RELIEF FOR ANY BREACH OF THIS AGREEMENT IN ANY OTHER COURT THAT HAS JURISDICTION OVER THE MATTER THAT IS REASONABLY NECESSARY TO OBTAIN SUCH RELIEF.

          13.5 Expenses. Except as otherwise provided in this Agreement, the Seller Parties, on the one hand, and the Buyer Parties, on the other hand, will bear all of their own costs, fees and expenses, if any, incurred by or on its behalf in connection with the transactions contemplated by this Agreement and the other Transaction Documents. The Holders will ensure that none of the costs, fees and expenses for which they are responsible will be charged to the Acquired Companies except the Transaction Costs.

          13.6 Disclosure Schedules. The inclusion of any information (including dollar amounts) in any of the schedules to this Agreement shall not be deemed to be an admission or acknowledgment by any Party that such information is required to be listed on such section of the relevant schedule or is material to or outside the Ordinary Course of Business of any Person. The information contained in this Agreement, the Exhibits hereto and the schedules is disclosed solely for purposes of this Agreement, and no information contained herein or therein shall be deemed to be an admission by any Party hereto to any third party of any matter whatsoever (including any violation of any Law or breach of contract). Unless the context otherwise requires, all capitalized terms used in the schedules shall have the respective meanings assigned in this Agreement. From and after the Execution Date until the earlier of two Business Days prior to the Closing Date or the termination of this Agreement in accordance with its terms, the Agent shall notify the Buyer Parties of any changes, additions, or events which cause any material change in or addition to any of the schedules delivered by the Seller Parties to the Buyer Parties on the Execution Date (collectively, the “Seller Disclosure Schedules”) promptly after the Agent becomes aware of the same by delivery of appropriate updates to the Seller Disclosure Schedules to the Buyer Parties. To the extent such supplemental disclosures to the Seller Disclosure Schedules relate to matters approved in writing by a Senior Vice President of Parent in accordance with the terms of this Agreement (including Section 8.1 (the “Approved Disclosures”)), such supplemental disclosures shall amend and supplement the Seller Disclosure Schedules delivered on the Execution Date. If the matters disclosed in such supplemental disclosures to the Seller Disclosure Schedules provided to the Buyer Parties have had or would reasonably be expected to have a Material Adverse Effect, the Buyer Parties may terminate this Agreement pursuant to Section 11.1(f) or this Section 13.6 if the Buyer Parties so notify the Agent within 10 Business Days after receiving such supplemental disclosures, after which Buyer Parties shall be deemed to have waived their rights to terminate this Agreement or prevent the consummation of the transactions contemplated by this Agreement pursuant to this Section 13.6 with respect to the information contained in such supplemental disclosures. Except as provided in the immediately preceding sentence, any such supplemental disclosures to the Seller Disclosure Schedules (other than any Approved Disclosures) shall be ignored for all purposes of this Agreement including the indemnification provisions in Article XII and the representations and warranties contained herein other than in connection with any Fraud assertion.

          13.7 Invalidity. In the event that any one or more of the provisions contained in this Agreement or in any other instrument referred to herein shall, for any reason, be held to be invalid, illegal or unenforceable in any respect, such invalidity, illegality or unenforceability shall not affect any other provision of this Agreement or any other such instrument.

          13.8 Third-Party Beneficiaries. This Agreement is solely for the benefit of (a) the Parties and their successors and assigns permitted under this Agreement, (b) the Acquired Company Indemnitees (solely with respect to such Acquired Company Indemnitees’ rights to

indemnification pursuant to Section 8.12), (c) the Buyer Indemnified Parties and the Holder Indemnified Parties (solely with respect to such Persons’ rights to indemnification pursuant to Article XII) and (d) the Persons referred to in Section 12.5(c) (solely with respect to such Person’s right to enforce the waivers set forth in such section) (all of whom shall be deemed to be third-party beneficiaries hereof for such purposes), and no provisions of this Agreement shall be deemed to confer upon any other Persons any remedy, Claim, liability, reimbursement, cause of action or other right or remedy by reason of this Agreement.

          13.9 No Presumption Against Any Party. Neither this Agreement nor any uncertainty or ambiguity herein shall be construed or resolved against any Party, whether under any rule of construction or otherwise. On the contrary, this Agreement has been reviewed by each of the Parties and their counsel and shall be construed and interpreted according to the ordinary meaning of the words used so as to fairly accomplish the purposes and intentions of all Parties.

          13.10 Specific Performance. Each of the Parties acknowledges and agrees that the other Party would be damaged irreparably in the event any of the provisions of this Agreement are not performed in accordance with their specific terms or otherwise are breached. Accordingly, each of the Parties agrees that the other Party shall be entitled, subject to compliance with Section 13.4, and in addition to any other remedies that may be available under this Agreement to an injunction or injunctions to prevent breaches of the provisions of this Agreement and to enforce specifically this Agreement and the terms and provisions hereof in any action instituted in any court of the United States or any state thereof having jurisdiction over the Parties and the matter, in addition to any other remedy to which they may be entitled, at law or in equity.

          13.11 Waiver of Certain Rights. Solely for purposes of the transactions contemplated by this Agreement, each Holder and each Acquired Company hereby waives any preferential purchase right, right of first refusal, right of first offer, purchase right, buy-sell right, tag-along right, drag-along right, preemptive right or other similar right that would interfere with the consummation of the transactions contemplated by this Agreement.

          13.12 Agent.

               (a) ▇▇▇▇▇▇▇▇ ▇▇▇▇▇ is hereby appointed by each Holder (and their respective successors and assigns) as agent and attorney-in-fact with full power of substitution (the “Agent”) for each Holder, for and on behalf of each Holder, as the party authorized to: (i) enter into and perform the Holders’ obligations under the Escrow Agreement; (ii) to negotiate, defend, dispute, contest, assert, compromise and settle all post-closing claims and matters arising under this Agreement, including those relating to any claim for indemnification under Article XII (including claims as to which a Holder or Holders become obligated pursuant to Section 12.6 to directly pay amounts to a Buyer Indemnified Party in respect of an indemnity claim) and to release all or any portion of the Escrow Funds to satisfy such claims; (iii) agree to, enter into settlements and compromises of, and demand arbitration and comply with orders of courts and awards of arbitrators with respect to such claims and matters, and to take all actions necessary or appropriate in the reasonable judgment of the Agent for the accomplishment of the foregoing, including authorizing releases of Escrow

Funds from the Escrow Account in connection therewith; (iv) initiate or refrain from initiating or dispute or refrain from disputing any claim for indemnification or other Claim under this Agreement; (v) take any other action expressly delegated to the Agent under the other terms of this Agreement and such other actions as may reasonably emanate therefrom; (vi) consent to and execute any amendment, waiver or consent of or under this Agreement or the Escrow Agreement; and (vii) give and receive notices and communications to or from the Seller Parties relating to the Transaction Documents and the transactions contemplated by the Transaction Documents, in each case without having to seek or obtain the consent of any Holder.

               (b) The Holders hereby agree that the Reimbursement Fund Amount shall be set aside and paid to the Agent and shall be available to the Agent to make any Final Holders Payment required under Section 3.2(d), to pursue and pay any expenses incurred in connection with the Retained Litigation, and to cover administrative and other expenses of the Agent associated with the performance of its obligations under this Section 13.12. If the Reimbursement Fund Amount is not sufficient to cover any Final Holders Payment or the third-party, out of pocket fees and expenses required to perform the obligations delegated to the Agent under this Agreement, the Agent shall notify the Holders of the estimated amount the Agent anticipates needing to satisfy such obligations. The Agent may (i) call capital from each Holder, in proportion to their Pro Rata Shares, to cover any such additional amounts, and each Holder shall deliver to the Agent its Pro Rata Share of the amount of capital called or (ii) fund such amounts out of any amount distributable to any Holder under this Agreement from and after the Closing, including any part of the Escrow Funds. If any Holder fails to fund its Pro Rata Share of such capital with 30 days of capital being called, the Agent may satisfy such payment obligation by bringing a claim against such defaulting party and/or offsetting any amount to which such defaulting party may be entitled under this Agreement (including such defaulting party’s portion of the Escrow Funds) plus interest at the rate of 5% from the date such capital was due to be funded to the date satisfied. The Agent may disburse all or any portion of the Reimbursement Fund Amount whenever it chooses and, subject to the foregoing right of offset, any amount so disbursed shall be disbursed pro rata to the Holders in the same proportions and using the same methodology as other disbursements are made to the Holders, which proportions and methodology are described in Section 13.12(c). Any portion of the Reimbursement Fund disbursed by the Agent to the Holders shall be treated for all Tax purposes as an adjustment to the Merger Consideration unless otherwise required by applicable Laws.

               (c) Any Escrow Shares received by the Agent for disbursement shall be disbursed to the Accredited Holders in whose name such Escrow Shares are issued.

               (d) Any Escrow Cash received by the Agent for disbursement shall be disbursed to the Non-Accredited Holders in proportion to each Non-Accredited Holder’s Non-Accredited Pro Rata Share of such Escrow Cash, minus (i) any amounts of Escrow Cash previously allocated to such Non-Accredited Holder as contemplated by Section 4.2(c) in respect of any indemnification obligation of such Non-Accredited Holder in this Agreement and (ii) if applicable, any amounts of Escrow Cash reserved in the Escrow Account pursuant to Section 4.2(d) and allocable to such Non-Accredited Holder.

               (e) Any Escrow Funds disbursed by the Agent to any of the Holders shall be treated for all Tax purposes as an adjustment to the Merger Consideration unless otherwise required by applicable Laws.

               (f) The Agent shall not be liable to any Holder for any act done or omitted hereunder as the Agent while acting in good faith and in the exercise of reasonable judgment. The Holders shall severally indemnify the Agent and hold the Agent harmless against any loss, liability or expense incurred without negligence, bad faith or willful misconduct on the part of the Agent and arising out of or in connection with the acceptance or administration of the Agent’s duties under this Agreement, including the reasonable fees and expenses of any legal counsel retained by the Agent. This right of indemnification shall survive the termination of this Agreement. The Holders hereby agree that the Agent shall be entitled to access the Reimbursement Fund Amount for the payment of amounts due in respect of the rights to indemnification described in Section 13.12(f) if the Agent establishes that he or she is intended to such indemnification. The Buyer Parties and any other Person dealing with the Agent is entitled to rely on the actions taken by, and consents and approvals given by, the Agent without the need for further investigation. The Buyer Parties and any other Person shall be entitled to rely on the Agent’s actions, consents and approvals notwithstanding any knowledge of the relying Person. Neither the Buyer Parties nor any other Person shall have any liability for relying on the Agent in the foregoing manner. Notwithstanding anything to the contrary in this Agreement, except in the case of criminal activity or Fraud, the Agent shall not be liable to the Buyer Parties for monetary damages for actions taken in his capacity as the Agent, and no Buyer Indemnified Party shall make any claim for such damages against the Agent.

               (g) If the Agent becomes unable or unwilling to serve as an Agent, such other Person or Persons as may be designated by a majority of the Holders, based on each Holder’s Pro Rata Share, shall succeed such Person as Agent. If the Agent should at any time become unwilling to serve as an Agent, it promptly shall so notify the Holders in writing, and shall bear no liability of any kind or nature whatsoever as a consequence of such determination. In addition, at any time as determined in the sole discretion of the Agent, the Agent may decline to take any action, make any determination, or otherwise bear any expense without having first obtained the approval or consent of holders of a majority of the Holders, based on each Holder’s Pro Rata Share.

               (h) For the avoidance of doubt, the Parties agree that (i) the duties and obligations undertaken by the Agent pursuant to this Agreement are undertaken by the Agent in an agency capacity, (ii) such duties and obligations are duties and obligations of the Holders, and the Holders shall cause the Agent to perform and fulfill all such duties and obligations, and (iii) references in this Agreement to the Agent (other than in this Section 13.12) are included merely for the economy and not because the Agent is the sole obligor of such duties and obligations.

          13.13 Guaranty. Parent hereby, unconditionally and irrevocably, guarantees (this “Guaranty”), by way of an independent obligation to the Seller Parties (a) the due, prompt and faithful performance by each Merger Sub of all undertakings, obligations, required acts and performances of such Merger Sub to the Seller Parties under or arising out of the obligations of

such Merger Sub under each Transaction Document; and (ii) the due and punctual payment of all amounts due and payable by each Merger Sub to the Seller Parties under or arising out of the obligations of such Merger Sub under each Transaction Document after the Execution Date, when and as the same shall arise and become due and payable in accordance with the terms of and subject to the conditions contained in such Transaction Document (the “Guaranteed Obligations”). Parent guarantees as principal obligor and not as surety the prompt performance and payment of all Guaranteed Obligations, this being a guarantee of payment and not a guarantee of collection. This Guaranty is not contingent upon the pursuit by the Seller Parties of any rights or remedies against either Merger Sub, such pursuit being hereby waived by Parent. The obligations, covenants, agreements and duties of Parent hereunder shall not be released, affected or impaired in any way by the voluntary or involuntary liquidation, sale or disposition of any assets of either Merger Sub, or the merger or consolidation of either Merger Sub with any other Person. This Guaranty shall be binding upon all successors and assigns of Parent.

          13.14 Role of Acquired Company Counsel; Waiver of Conflicts and Privilege.

               (a) Each of the Parties acknowledges and agrees that in connection with the matters related to this Agreement, ▇▇▇▇▇▇ & ▇▇▇▇▇▇ L.L.P. and ▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇ ▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇ & ▇▇▇▇▇▇▇, L.L.P. solely represented the Acquired Companies and did not represent any of the Holders or any officer, employee, director or manager of any Acquired Company individually.

               (b) Each of the Buyer Parties waives and will not assert, and agrees to cause each Surviving Entity and its Subsidiaries to waive and to not assert, any conflict of interest arising out of or relating to the potential representation, after the Closing (the “Post Closing Representation”), of any Holder or any officer, employee, director or manager of either Acquired Company (any such Person, a “Designated Person”) in any matter involving this Agreement or the transactions contemplated hereby, by any legal counsel (including ▇▇▇▇▇▇ & ▇▇▇▇▇▇ L.L.P.) currently representing either Acquired Company in connection with this Agreement or the transactions contemplated by this Agreement (the “Current Representation”).

               (c) Each of the Buyer Parties waives and will not assert, and agrees to cause each Surviving Entity and its Subsidiaries to waive and to not assert, any attorney-client privilege with respect to any communication between any such legal counsel (including ▇▇▇▇▇▇ & ▇▇▇▇▇▇ L.L.P.) and any Designated Person occurring during the Current Representation in connection with any Post-Closing Representation, including in connection with a dispute with any Buyer Party and, following the Closing, with either Surviving Entity or any of its Subsidiaries, it being the intention of the Parties that following the Closing all such rights to such attorney-client privilege and to control such attorney-client privilege shall be exclusively vested in and belong to the Holders; provided that the foregoing waiver and acknowledgement of retention shall not extend to (i) any communication not involving this Agreement or the transactions contemplated by this Agreement, or to communications with any Person other than the Designated Persons and their advisors and (ii) matters involving a third party as to which Buyer Parties, the Surviving Entities and their Subsidiaries, as applicable, shall be permitted to assert the attorney-client privilege.

          13.15 Counterparts. This Agreement may be executed in any number of counterparts, each of which shall be deemed an original and all of which together shall constitute but one and the same instrument. Facsimile or scanned and emailed transmission of any signed original document or retransmission of any signed facsimile or scanned and emailed transmission will be deemed the same as delivery of an original. At the request of any Party, the Parties will confirm facsimile or scanned and emailed transmission by signing a duplicate original document.

          13.16 Entire Agreement; Amendments.

               (a) This Agreement, together with all Exhibits, Annexes and Schedules hereto, the other Transaction Documents and the Confidentiality Agreements constitute the entire agreement among the Parties pertaining to the subject matter hereof and thereof and supersedes all prior and contemporaneous agreements, understandings, negotiations and discussions, whether oral or written, of the Parties, including the Term Letter dated May 17, 2011.

               (b) This Agreement may be amended, modified, supplemented or restated, and any of the terms, covenants, representations, warranties or conditions hereof may be waived, only by a written instrument executed by the Buyer Parties and the Agent or, in the case of a waiver, by or on behalf of the Buyer Parties (if any Buyer Party is waiving compliance) or the Agent (if the Seller Parties are waiving compliance). The failure of any Party at any time or times to require performance of any provisions hereof will in no manner affect the right at a later time to enforce the same. No waiver by any Party of any condition, or of any breach of any term, covenant, representation or warranty contained in this Agreement, in any one or more instances, will be deemed to be or construed as a further or continuing waiver of any such condition or breach or a waiver of any other condition or of any breach of any other term, covenant, representation or warranty.

          13.17 Time of the Essence. Time is of the essence in the performance of this Agreement.
