(a) Closing Balance Sheet. (i) The Purchaser shall prepare (with the assistance of Master LLC) and deliver to Parent within 60 days following the Closing Date:

(A) an unaudited consolidated balance sheet of the Companies dated as of the Closing Date (the “Closing Balance Sheet”), and giving effect to the Medifax Contribution and the transactions contemplated by this Agreement to occur prior to the Closing (but not taking into account the Financing and payment of the Minimum Cash Balance in Section 2.15(b)), including the actions described in Section 2.10, consistent with the Year End Audited Balance Sheet and prepared in accordance with Section 2.14(a)(ii), except for the absence of footnotes and other items that are not typically included in an unaudited balance sheet; and

(B) a statement (the “Closing Net Working Capital Statement”) setting forth the Net Working Capital of the Companies as of the Closing Date (the “Closing Net Working Capital”), prepared in accordance with Section 2.14(a)(ii) and giving effect to the Medifax Contribution and the transactions contemplated by this Agreement to occur prior to the Closing (but not taking into account the Financing and payment of the Minimum Cash Balance in Section 2.15(b)), including the actions described in Section 2.10.

(b) Disputes. (i) Parent and its representatives shall be given timely access to all supporting documents and work papers used in the preparation of the Closing Net Working Capital Statement and the Closing Balance Sheet and such Books and Records, facilities and

employees of the Companies and Master LLC as it may reasonably request, in connection with its review of the Closing Net Working Capital Statement and the Closing Balance Sheet.

(ii) Parent may dispute any amounts reflected on the Closing Net Working Capital Statement or the Closing Balance Sheet. If Parent elects to dispute any such amount, Parent shall notify the Purchaser in writing of each disputed item on the Closing Net Working Capital Statement, specifying the amount thereof in dispute and setting forth, in reasonable detail, the basis for such dispute, within 45 days of the Purchaser’s delivery of the Closing Balance Sheet and the Closing Net Working Capital Statement under Section 2.14(a)(i) to Parent, with any amount not so disputed being final and binding on the parties in accordance with Section 2.14(c). In the event of such a dispute, Parent and the Purchaser shall attempt to reconcile their differences. If Parent and the Purchaser are unable to reach a resolution within 30 days after receipt by the Purchaser of Parent’s written notice of dispute, Parent and the Purchaser shall submit the items remaining in dispute for resolution to Deloitte & Touche LLP (or, if such firm shall decline or is unable to act or is not, at the time of such submission, independent of the Purchaser and Parent, to another independent accounting firm of international reputation mutually acceptable to Parent and the Purchaser) (either Deloitte & Touche LLP or such other accounting firm being referred to herein as the “Independent Accounting Firm”), which shall, as soon as practicable after such submission, determine and report to Parent and the Purchaser upon such remaining disputed items, and such report shall be final and binding on Parent and the Purchaser. The Independent Accounting Firm shall address only those items in dispute and may not assign a value greater than the greatest value for such item claimed by either party or smaller than the smallest value for such item claimed by either party. If the Independent Accounting Firm resolves all disputes presented to it entirely in the manner proposed by Parent or the Purchaser, as the case may be, the fees and expenses of the Independent Accounting Firm relating to the resolution of such dispute shall be paid by the other party. In all other events, the fees and expenses of the Independent Accounting Firm shall be shared based on the difference between Parent’s position, on the one hand, and the Purchaser’s position, on the other hand, initially presented to the Independent Accounting Firm (based on the aggregate of all differences taken as a whole) and the final resolution as determined by the Independent Accounting Firm in proportion to the total difference between Parent’s and the Purchaser’s initial positions.

(c) Post-Closing Adjustment Payments. The Closing Balance Sheet and the Closing Net Working Capital Statement shall be deemed final for the purposes of this Section 2.14 and binding on the parties upon the earliest of (i) the failure of Parent to timely notify the Purchaser of a dispute in accordance with Section 2.14(b)(ii), (ii) the resolution of all disputes by Parent and the Purchaser and (iii) the resolution of all disputes by the Independent Accounting Firm. Within two Business Days of the Closing Balance Sheet and the Closing Net Working Capital Statement being deemed final, an adjustment payment shall be made as follows, by wire transfer in immediately available funds to Holdco 1 and Holdco 2, pro rata in accordance with their respective interests in Master LLC, or to Master LLC, as applicable:

(A) (x) If the Closing Net Working Capital exceeds the Estimated Net Working Capital, then Master LLC shall pay an amount equal to

the full amount of the excess of Closing Net Working Capital over Estimated Net Working Capital to Holdco 1 and Holdco 2, pro rata in accordance with their respective interests in Master LLC, by wire transfer of immediately available funds; provided, however, that, no such payment shall be made if the excess of Closing Net Working Capital over Target Net Working Capital is not greater than $2.5 million; or

(y) If the Closing Net Working Capital is less than the Estimated Net Working Capital, then Holdco 1 and Holdco 2, pro rata in accordance with their respective interests in Master LLC, shall pay an amount equal to such shortfall to Master LLC by wire transfer of immediately available funds; provided, however, that if either Holdco 1 or Holdco 2 is unable or unwilling to pay such amount, Parent shall be liable for such payments and provided, further, that, no such payment shall be made if Closing Net Working Capital is not less than Target Net Working Capital by an amount greater than $2.5 million; and

(B) (x) If an adjustment to the LLC Merger Consideration was made pursuant to Section 2.13(c)(i) and it is subsequently determined pursuant to this Section 2.14 that the Closing Net Working Capital does not exceed Target Net Working Capital by more than $2.5 million, then Holdco 1 and Holdco 2, pro rata in accordance with their respective interests in Master LLC, shall pay to Master LLC by wire transfer of immediately available funds an amount equal to the amount by which the LLC Merger Consideration was increased pursuant to Section 2.13(c)(i); provided, however, that if either Holdco 1 or Holdco 2 is unable or unwilling to pay such amount, Parent shall be liable for such payments; or

(y) If an adjustment to the LLC Merger Consideration was made pursuant to Section 2.13(c)(ii) and it is subsequently determined pursuant to this Section 2.14 that the Closing Net Working Capital is not less than Target Net Working Capital by more than $2.5 million, then Master LLC shall pay to Parent by wire transfer of immediately available funds an amount equal to the amount by which the LLC Merger Consideration was decreased pursuant to Section 2.13(c)(ii).

Section 2.15 Contribution of Medifax; Post-Closing Distributions.

(a) On the Closing Date and immediately after the Corporate Merger Effective Time, (i) Medifax shall pay $190,000,000 in immediately available funds to Holdco 1 in full satisfaction of all amounts outstanding on the Medifax Note and (ii) following such payment, Holdco 1 will contribute the Medifax Shares to the Master LLC (the “Medifax Contribution”).

The End Date for each Parent Service shall not be later than the “Outside Date” (as such term is defined in the Transition Services Agreement) with respect to such Parent Service as set forth on the annexes to the Transition Services Agreement. If the Purchaser does not specify an End Date with respect to any Parent Service, the End Date for such Service shall be deemed to be the Outside Date applicable to such Parent Service as set forth on the annexes to the Transition Services Agreement.

ARTICLE VI
EMPLOYEE MATTERS

Section 6.01 Employee Benefits. (a) Master LLC agrees to notify Parent in writing as promptly as practicable following the termination of employment of any employee who is a party to the letter agreements set forth in paragraph 1 of Section 3.09 of the Disclosure Schedule and such notice shall include in reasonable detail the reasons for such termination.

(b) As of the Closing, Master LLC agrees to provide, or to cause the Companies to provide, the employees of the Companies, for a period of one year after the Closing (or, if earlier, until December 31, 2007), with employee benefits that are, in the aggregate substantially equivalent to those non-equity benefits (under any stock option, stock purchase or restricted stock plan, program or agreement or otherwise) provided to similarly situated employees of Master LLC and the Companies immediately prior to the Closing and, in the aggregate, at no substantial increase in cost to employees of the Companies; provided, however, that nothing herein shall prohibit Master LLC or any Company from terminating any employee, subject to the provisions of applicable Law and applicable Contracts.

(c) With respect to any employee benefit plan of Master LLC or a Company in which the employees of the Companies participate pursuant to Section 6.01(b), Master LLC shall, or shall cause the Companies to: (i) waive all limitations as to pre-existing condition exclusions and waiting periods applicable to such employees to the same extent such exclusions and waiting periods would have been waived or would otherwise not be excluded or required under the plans in which such employees were participating immediately prior to the Closing; (ii) credit all deductibles and co-pays under any of Parent’s or any of its Affiliates’ health plans, during the applicable plan year that includes the Closing, towards deductibles and co-pays under the health plan of Master LLC or a Company, as the case may be; and (iii) recognize all service of such employees with Parent or any of its Affiliates for purposes of eligibility to participate, vesting and benefit accrual under any employee benefit plan, severance policy, vacation, sick, holiday or other paid leave policy of Master LLC or a Company in which such employees may be eligible to participate after the Closing, in each case, to the same extent taken into account under the corresponding plan or policy in which such employees participated immediately prior to the Closing; provided, however, that this provision shall not be construed in any way that would result in a duplication of benefits provided to any such employee.

(d) As soon as practicable following the Closing Date, Parent shall cause the trustee of the trust established under the Emdeon 401(k) Savings and Employee Stock Ownership Plan (the “Emdeon Savings Plan”) to transfer to the trustee of the trust established under such defined contribution plan as shall be designated by Master LLC (the “New Plan”) all assets and liabilities, as of the date of such transfer, attributable to the accounts under the Emdeon Savings Plan of each person who, on the Closing Date, is an employee of any of the Companies. Such transfer shall be in cash or in kind as reasonably agreed to by Parent and Master LLC, provided that, (i) to the extent such accounts hold securities of Parent, such transfer shall be in kind and (ii) all participant loans shall be transferred in kind. Master LLC shall cause the trustee of the trust established under the New Plan to accept such transfer. Notwithstanding the foregoing, the amount transferred shall in no event be less than the amount required to satisfy the requirements of Section 414(l) of the Code. No loan from the Emdeon Savings Plan shall be treated or declared in default solely by reason of the transactions contemplated by this Agreement.

(e) If the Closing Date occurs prior to January 1, 2007, Parent shall transfer to Master LLC and Master LLC shall accept the flexible spending account elections and account liabilities (maintained pursuant to Code Sections 105, 125 and 129) under a flexible spending account plan maintained by Parent (or its affiliates) of each person who, on the Closing Date, is an employee of any of the Companies and Parent shall transfer to Master LLC the aggregate net

cash amount (determined immediately prior to transfer) for contributions paid but not yet reimbursed for such employees.

ARTICLE VII
TAX MATTERS

Section 7.01 Tax Indemnities. (a) Parent shall be responsible for and shall indemnify and hold the Purchaser, Master LLC and their respective Affiliates harmless against all Losses arising out of or arising from any (i) Excluded Tax and (ii) any breach by Parent or any of its Affiliates of any covenant by Parent or its Affiliates set forth in this Article VII. Master LLC shall be responsible for and shall indemnify and hold Parent and its Affiliates harmless against all Losses arising out of Taxes (other than Excluded Taxes) of Master LLC or the Companies (or attributable to the operation of their businesses) that are imposed on Parent or its Affiliates, but should have been imposed on Master LLC or any of the Companies; for the avoidance of doubt, such indemnity shall not cover Taxes attributable to allocations of taxable income to the Parent Members or their Affiliates pursuant to the LLC Agreement or otherwise as a result of Parent Members’ capacity as members of Master LLC. Master LLC shall also be responsible for and shall indemnify Purchaser and its Affiliates harmless against all Losses arising out of Taxes of Master LLC or the Companies (or attributable to the operation of their businesses) that are imposed on Purchaser or its Affiliates, but should have been imposed on Master LLC or any of the Companies; for the avoidance of doubt, such indemnity shall not cover Taxes attributable to allocations of taxable income to the Purchaser or their Affiliates pursuant to the LLC Agreement or otherwise as a result of the Purchaser’s capacity as a member of Master LLC. Master LLC shall indemnify and hold the Purchaser, Parent and their respective Affiliates harmless against all Losses arising out of or arising from any breach by Master LLC or any Company of any covenant by Master LLC or any Company to such indemnified person or its Affiliates set forth in this Article VII. Purchaser shall indemnify and hold Parent and its Affiliates harmless against all Losses arising out of or arising from any breach by the Purchaser or its Affiliates of any covenant by the Purchaser or its Affiliates set forth in this Article VII. For purposes of this Section 7.01(a), Master LLC and the Companies shall not be considered Affiliates of the Purchaser.

(b) In the case of Taxes that are payable with respect to a Straddle Period, the portion of any such Tax that is allocable to the portion of the taxable period ending on the date of the Closing shall be:

(i) in the case of Taxes that are either (x) based upon or related to income or receipts or (y) imposed in connection with any sale or other transfer or assignment of property (real or personal, tangible or intangible), deemed equal to the amount which would be payable (after giving effect to amounts which may be deducted from or offset against such Taxes) if the taxable period ended on the date of the Closing; and

(ii) in the case of Taxes imposed on a periodic basis with respect to the assets of the Companies, or otherwise measured by the level of any item, deemed to be the amount of such Taxes for the entire Straddle Period (after giving effect to amounts which may be deducted from or offset against such Taxes) (or, in the case of such Taxes

determined on an arrears basis, the amount of such Taxes for the immediately preceding period), multiplied by a fraction the numerator of which is the number of days in the period ending on the date of the Closing and the denominator of which is the number of days in the entire Straddle Period.

(c) Any credit or refund resulting from an overpayment of Taxes for a Straddle Period shall be allocated to the portion of the Straddle Period ending on the Closing Date and/or the portion of the Straddle Period beginning after the Closing Date based upon the method employed in Sections 7.01(b)(i) and (b)(ii) above taking into account the type of Tax to which the credit or refund relates. In the case of any Tax based upon or measured by capital (including net worth or long-term debt) or intangibles, any amount thereof required to be allocated under this Section 7.01(c) shall be computed by reference to the level of such items on the date of the Closing. All determinations necessary to effect the foregoing allocations shall be made in a manner consistent with prior practice of the Companies or any of their respective Subsidiaries as the case may be.

(d) Payment by the indemnifying party of any amount due under this Section 7.01 shall be made within 10 days following written notice by the indemnified party that payment of such amounts to the appropriate taxing authority is due; provided, that the indemnifying party shall not be required to make any payment earlier than two days before the Taxes to which such indemnification payment relates are due to the appropriate taxing authority. Notwithstanding anything to the contrary herein, if Parent receives an assessment or other notice of Taxes due with respect to the Companies for which Parent is not responsible, in whole or in part, pursuant to paragraph (a) of this Section 7.01, then Master LLC shall pay such Taxes, or if Parent pays such Taxes, then Master LLC or the Companies shall pay to Parent the amount of such Taxes for which Parent is not responsible within five days following such payment. In the case of a Tax that is contested in accordance with the provisions of Section 7.03, payment of the Tax to the appropriate taxing authority will be considered to be due no earlier than the date a final determination to such effect is made by the appropriate taxing authority or court.

(e) Transactions occurring or actions taken on the Closing Date but after the Closing outside the ordinary course of business of Master LLC or the Companies shall be treated as occurring on the next day and, as such, shall for purposes of this Agreement and the LLC Agreement be treated (and consistently reported by the parties) as occurring in the taxable period (or portion thereof) beginning the day after the Closing Date.

Section 7.02 Tax Refunds. (a) Any Tax refund or credit (including any interest paid or credited with respect thereto) relating to taxable periods (or portions of taxable period) ending on or before the date of the Closing shall be for the benefit and the property of Parent. If such Tax refund or credit is received by Master LLC or the Companies, Master LLC or the appropriate Company, as the case may be, shall promptly pay over to Parent the amount of such refund or, in the case of a credit, the amount of such credit as such credit is actually used to reduce a cash payment for Taxes (in each case, as determined on a “with and without” basis and reduced by any income Taxes resulting from receiving such refund or credit or the right to receive such refund or credit payable by Master LLC or the Companies). Master LLC shall, if Parent so requests and at Parent’s expense, cause the Companies or other relevant entity to file for and use its reasonable best efforts to obtain and expedite the receipt of any refund to which

Parent is entitled under this Section 7.02. Master LLC shall permit Parent to participate in (at Parent’s expense) the prosecution of any such refund claim.

(b) Any amount otherwise payable by Parent under Section 7.01 shall be reduced by any Tax Benefit actually received by Master LLC, its members or the Companies in a taxable period (or portion thereof) beginning after the Closing Date as a result of the Tax payment or any underlying adjustment resulting in the obligation of Master LLC, its members or the Companies to pay Taxes or other amounts for which Parent is responsible under Section 7.01 or the accrual or payment of such Taxes. If and to the extent the Tax payment or underlying adjustment gives rise to a deduction for income Tax purpose that can be allocated to the Parent Members in accordance with the LLC Agreement (including by means of a special allocation of such deduction), there shall be no reduction in the amount of the indemnification payment payable by Parent under Section 7.01 and there shall be no obligation to make a payment to the indemnifying party in respect of such Tax Benefit; provided, that if such allocation to the Parent Members is subsequently disallowed in whole or in part and such disallowance results in any Tax Benefits described in the first sentence hereof, the amount of such Tax Benefit shall promptly be paid to Parent. If an indemnification payment has been reduced on account of a Tax Benefit pursuant to this Section 7.02(b) (or if a payment has been made by the indemnified party to Parent in respect of a Tax Benefit pursuant to this Section 7.02(b)) and if such Tax Benefit is subsequently disallowed (in whole or in part) by a Governmental Authority, then Parent shall remit to the appropriate indemnified party the amount of the disallowed Tax Benefit, together with any additional amount to reimburse the indemnified party for any interest imposed by the applicable Governmental Authority.

Section 7.03 Contests. (a) After the Closing, Parent, Purchaser and Master LLC shall promptly notify each other in writing of any proposed assessment or the commencement of any Tax audit or administrative or judicial proceeding (a “Contest”) which could result in a claim for indemnification under Section 7.01; provided, that no such notice is required if the indemnifying party has actual notice of such contest. Such notice shall contain factual information (to the extent known to such party) describing the asserted Tax liability in reasonable detail and shall include copies of any notice or other document received from any taxing authority in respect of any such asserted Tax liability. If any party fails to give the other parties prompt notice of an asserted Tax liability as required by this Section 7.03, then such parties shall not have any obligation to indemnify for any loss arising out of such asserted Tax liability, but only to the extent that such failure to give such notice results in a detriment to the indemnifying party.

(b) In the case of a Contest that relates to taxable periods ending on or before the date of the Closing, Parent shall have the sole right, at its expense, to control the conduct of such Contest; provided, however, that Parent shall not settle or compromise any asserted liability with respect to any such Contest without the prior written consent of the Purchaser if such settlement or compromise would adversely affect the Tax liability of the Purchaser, its Affiliates, Master LLC or the Companies in a post-Closing Tax period, which consent shall not be unreasonably withheld or delayed.

(c) With respect to Straddle Periods, Parent may elect to direct and control, through counsel of its own choosing, any Contest involving any asserted Tax liability with

respect to which indemnity may be sought from Parent pursuant to Section 7.01. If Parent elects to direct such Contest, Parent shall within thirty (30) days of receipt of the notice regarding such Contest notify Master LLC of its intent to do so, and Master LLC shall cooperate and shall cause the Companies to cooperate, at Parent’s expense, in each phase of such Contest. If Parent elects to direct such Contest, then Master LLC may participate in such Contest, at Master LLC’s expense. If Parent elects not to direct the Contest, Master LLC may assume control of such Contest (at Master LLC’s expense). If Master LLC assumes control of such Contest, then Parent may participate, at its own expense, in the Contest. Neither Parent nor Master LLC may settle or compromise any asserted liability with respect to any Contest governed by this Section 7.03(c) without prior written consent of the other party, which shall not be unreasonably withheld or delayed.

(d) Master LLC and Parent agree to cooperate, and agree to cause their Affiliates to reasonably cooperate, in the defense against or compromise of any claim in any Contest.

Section 7.04 Preparation of Tax Returns. (a) Parent shall prepare and file (or cause the Companies to prepare and file) all income and franchise Tax Returns relating to the Companies for taxable periods ending on or before the date of the Closing and all other Tax Returns required to be filed prior to the Closing Date. All expenses (excluding internal overhead any Company) incurred subsequent to the Closing in connection with the preparation of the Tax Returns described in this Section 7.04(a) and not included in the determination of Closing Net Working Capital shall be borne by Parent. To the extent applicable, such Tax Returns shall be prepared on a basis consistent with those prepared for prior taxable periods except where a different treatment of an item is required by an intervening change in Law.

(b) Master LLC shall prepare and file (or cause the Companies to prepare and file), in accordance with the LLC Agreement, all Tax Returns of the Companies that are not prepared by Parent pursuant to subparagraph (a) above (including for Straddle Periods); it being understood that Master LLC shall remit, or cause the appropriate Company to remit, to the appropriate Governmental Authority all Taxes required to be paid by Master LLC or any Company in respect of such Tax Returns subject to reimbursement or contribution by Parent in respect of the portion of such Taxes for which Parent is responsible pursuant to Section 7.01, which Parent shall pay in accordance with this Article VII. With respect to any such Tax Return that begins prior to the Closing Date or as to which Taxes are otherwise allocable to Parent under Section 7.01 hereof, Master LLC shall provide Parent and its authorized representative with a copy of such completed Tax Return and a statement (with which Master LLC will make available supporting schedules and information) certifying the amount of Tax shown on such Tax Return that is allocable to Parent pursuant to Section 7.01 at least 30 days prior to the due date (including any extension thereof) for filing of such Tax Return, and Parent and its authorized representative shall have the right to review and approve (not to be unreasonably withheld or delayed) such Tax Return and statement prior to the filing of such Tax Return. Parent and Master LLC agree to consult and to attempt in good faith to resolve any issues arising as a result of the review of such Tax Return and statement by Parent or its authorized representative. If Purchaser and Parent cannot resolve such dispute, then Parent and the Purchaser shall submit the items in dispute for resolution to the Independent Accounting Firm (or, if such firm declines or is unable to act, or is not, at the time of such submission,

independent of the Purchaser, Master LLC and Parent, then to another independent accounting firm of international reputation mutually acceptable to Parent and the Purchaser), which shall, as soon as practicable after such submission, determine and report to Parent and the Purchaser its resolution of such disputed items. The report of such firm shall be final and binding upon the parties hereto. The fees for such firm shall be paid in the same manner as the Independent Accounting Firm as described in Section 2.14(b).

Section 7.05 Tax Cooperation and Exchange of Information. Parent and Master LLC shall provide each other with such cooperation and information as either of them reasonably may request of the other (and Master LLC shall cause the Companies to provide such cooperation and information) in filing any Tax Return, amended Tax Return or claim for refund, determining a liability for Taxes or a right to a refund of Taxes or participating in or conducting any audit or other proceeding in respect of Taxes. Such cooperation and information shall include providing copies of relevant Tax Returns or portions thereof, together with related work papers and documents relating to rulings or other determinations by taxing authorities. Parent and Master LLC shall make themselves (and their respective employees) reasonably available on a mutually convenient basis to provide explanations of any documents or information provided under this Section 7.05. Notwithstanding anything to the contrary in Section 5.02, each of Parent and Master LLC shall retain all Tax Returns, work papers and all material records or other documents in its possession (or in the possession of its Affiliates) relating to Tax matters of the Companies for any taxable period that includes the date of the Closing and for all prior taxable periods until the later of (i) the expiration of the statute of limitations of the taxable periods to which such Tax Returns and other documents relate, without regard to extensions or (ii) six years following the due date (without extension) for such Tax Returns. After such time, before Parent or Master LLC shall dispose of any such documents in its possession (or in the possession of its Affiliates), the other party shall be given an opportunity, after 90 days prior written notice, to remove and retain all or any part of such documents as such other party may select (at such other party’s expense). Any information obtained under this Section 7.05 shall be kept confidential, except as may be otherwise necessary in connection with the filing of Tax Returns or claims for refund or in conducting an audit or other proceeding.

Section 7.06 Tax Covenants. Neither Master LLC nor any Affiliate of Master LLC shall amend, refile or otherwise modify, or cause or permit any Company to amend, refile or otherwise modify, any Tax election or Tax Return with respect to any taxable period (or portion of any taxable period), ending on or before the date of the Closing without the prior written consent of Parent.

Section 7.07 Miscellaneous. (a) For purposes of this Article VII, all references to Master LLC, Parent, Affiliates or the Companies include successors.

(b) Notwithstanding any provision in this Agreement to the contrary, the covenants and agreements of the parties hereto contained in this Article VII, the representations and warranties contained in Section 3.15 (to the extent such representations and warranties cover Tax matters) and Section 3.16 shall survive the Closing and shall remain in full force until sixty (60) days after the expiration of the applicable statutes of limitations for the Taxes in question (taking into account any extensions or waivers thereof).

(c) Except for this Agreement, any Tax sharing agreement or arrangement between Parent or any of its Affiliates (other than the Companies), on the one hand, and any of the Companies, on the other hand, shall be terminated, and all payments thereunder settled, immediately prior to the Closing with no payments permitted to be made thereunder on or after the Closing Date.

(d) Payments by Parent under this Article VII shall be net of any insurance, indemnification or other recoveries actually paid to Master LLC, the Companies or any of their respective Subsidiaries or any Affiliates of Master LLC under any insurance policy (net of any increase in premiums required to be paid as a result of such recovery) or any other Contract in connection with the facts giving rise to the right of indemnification.

(e) The Parent Members and the Purchaser agree to cause an election under Section 754 of the Code to be made by Master LLC for the taxable year that includes the LLC Merger Effective Time.

(f) The parties shall treat for all income Tax purposes any indemnification payment made in accordance with this Article VII (i) that is paid to the Purchaser, as an adjustment to the LLC Cash Merger Consideration, and (ii) that is paid to or by Master LLC, as an adjustment to the net fair market value of Master LLC as of the date of the Closing.

Section 7.08 Tax Treatment of Merger Transaction.

(a) For federal and state income Tax purposes, the parties hereto agree to treat and report the LLC Merger as follows: (i) first, so much of the LLC Cash Merger Consideration derived from borrowings under the Debt Financing or the Alternative Financing shall be treated as having been distributed to the Parent Members in pro rata reduction of their equity interests in Master LLC (except to the extent required by Section 707(a) of the Code and the Regulations promulgated thereunder), and (ii) following such distribution, each of the Parent Members shall be deemed to have sold 52% of its membership interests in Master LLC directly to the Purchaser for the remainder of the cash proceeds disbursed to the Parent Members. In connection with the foregoing, not later than 90 days following the Closing, Parent shall provide the Purchaser with an allocation of the enterprise value of Master LLC among its assets (the “Allocation”) for the Purchaser’s review and approval, which approval shall not be unreasonably withheld. As a subpart of the Allocation, Parent is authorized to have Master LLC engage a valuation firm acceptable to the Purchaser to conduct a formal valuation study to identify and value the identifiable intangibles of the Companies for financial reporting and tax purposes. The Allocation shall be used by the parties hereto for all relevant income Tax purposes pertaining to the transactions contemplated by this Agreement, including the establishment of “initial gross asset values” for Master LLC’s assets and the Purchaser’s adjustments under Section 754 of the Code in respect of its membership interests. If Parent and the Purchaser cannot agree on the proper Allocation, then Parent and the Purchaser shall submit the items in dispute for resolution to an independent valuation or accounting firm of international reputation mutually acceptable to Parent and the Purchaser, which shall, as soon as practicable after such submission, determine and report to Parent and the Purchaser its resolution of such disputed items. The report of such firm shall be final and binding upon the parties hereto. The fees for such firm shall be paid in the same manner as the Independent Accounting Firm as described in Section 2.14(b). The

Allocation shall be binding upon the Purchaser, Master LLC and Parent and none of them (nor any of their Affiliates) shall file any Tax Return, or take a position with a Tax authority, that is inconsistent with the Allocation. Parent and Purchaser hereby agree to revise the Allocation to reflect any adjustment made to the LLC Cash Merger Consideration pursuant to Section 2.14.

(b) For federal and state income Tax purposes, the parties hereto agree to treat and report the Corporate Merger as if the cash proceeds disbursed in the merger were borrowed by Medifax under the Financing or the Alternative Financing and paid to Parent or Holdco 1, as applicable, in satisfaction of the Medifax Note.

Section 7.09 Options; Restricted Stock.

(a) Options. In the event that subsequent to the Closing Date any current or former employee of a Company exercises options to purchase stock of Parent which options were received by such employee in connection with the performance of services for such Company or its Affiliates, as the case may be, and are outstanding on the Closing Date (the “Parent Options”), Parent and Master LLC agree and acknowledge that they shall report the exercise of the Parent Options in accordance with Section 7.09(c). Master LLC shall (or shall cause its Affiliate to) immediately inform Parent of any event that results in the forfeiture of any Parent Options by any person holding such options.

(b) Restricted Stock. In the event that subsequent to the Closing Date any current or former employee of a Company becomes vested (in whole or in part) in any restricted stock of Parent which (i) was received by such employee in connection with the performance of services for such Company or its Affiliates, as the case may be, and (ii) with respect to which an effective election under Section 83(b) of the Code was not made (the “Parent Restricted Stock”), Parent and Master LLC agree and acknowledge that they shall report the vesting of the Parent Restricted Stock in accordance with Section 7.09(c). Master LLC shall (or shall cause its Affiliate to) immediately inform Parent of any event that results in the vesting or forfeiture of any of the Parent Restricted Stock.

(c) Compensation Expense; Employment Taxes; Reimbursement. Upon the exercise of the Parent Options or the vesting of the Parent Restricted Stock, as applicable, except as set forth in subsection (e) below, Parent (and not Master LLC or any of its Affiliates) shall (i) claim the compensation expense deduction associated with such exercise or vesting measured by the fair market value of the Parent stock at the time of such exercise (less the exercise price) or vesting (the “Compensation Deduction”), (ii) pay all employment and withholding Taxes resulting from such exercise or vesting and (iii) file all Tax Returns related to the payment of such employment and withholding Taxes. Parent shall have the right to control, and shall be fully responsible and indemnify Master LLC, the Companies, Purchaser and its Affiliates for any expenses incurred in connection with, any Contest challenging the Compensation Deduction.

(d) If, upon the subsequent disposition of an audit or other examination by a Governmental Authority (whether by settlement or otherwise), it is determined that a Compensation Deduction claimed by Parent should properly have been reported by Master LLC or one of its Affiliates and not by Parent, then:

(i) Parent shall notify Master LLC (if Master LLC has not already received such notice) and shall provide Master LLC with adequate information so that it can reflect the Compensation Deduction on the appropriate Tax Returns; and

(ii) Master LLC (to the extent the Compensation Deduction was reportable by it or one of its subsidiaries that is not treated as a corporation for federal income Tax purposes) shall specially allocate the deduction to the Parent Members pro rata in proportion to their respective number of Units (and the Parent Members shall also be credited in a similar fashion with a cash capital contribution to fund the compensation to which the Compensation Deduction relates); provided, that if the Compensation Deduction is properly claimed by a subsidiary of Master LLC that is treated as a corporation for federal income tax purposes, such subsidiary shall pay, subject to Section 7.09(f), Parent the amount of any Tax Benefits actually realized by such subsidiary that relates to any adjustments resulting from such Compensation Deduction within 30 days of the date such Tax Benefits are actually realized.

(e) If, the Compensation Deduction relates to services performed for Medifax or another direct or indirect subsidiary of Master LLC that is treated as a corporation for federal income Tax purposes and such Compensation Deduction is required to be claimed by such subsidiary in its taxable year that begins after the Closing Date, such subsidiary shall (i) claim the Compensation Deduction, (ii) pay all employment and withholding Taxes resulting from the exercise or vesting of the related Parent Options or Parent Restricted Stock, (iii) file all Tax Returns related to the payment of such employment and withholding Taxes, and (iv) subject to Section 7.09(f), pay over to Parent the amount of any Tax Benefits actually realized by such corporation or its Affiliates as a result of the Compensation Deduction, minus the employer share of any employment Taxes described in clause (ii) above, within 30 days of the date such Tax Benefits are actually realized. In connection with the delivery of Parent stock to the employee upon exercise of the Parent Option or vesting of the Parent Restricted Stock, Parent will be responsible for withholding the amount of withholding Taxes and the employees’ share of employment Taxes described in clause (ii) above and shall promptly remit such amount to Medifax or any other direct or indirect subsidiary of Master LLC that is treated as a corporation for federal income Tax purposes, as the case may be. The parties agree that the transactions described in this paragraph (e) shall be reported for tax purposes as a purchase, by the applicable corporate subsidiary of Master LLC, of the Parent stock transferred to the employee for an amount equal to its fair market value (a portion of which purchase price is satisfied by the payment described in clause (iv)) and a concurrent capital contribution by Parent to such corporate subsidiary of cash equal to the purchase price of the stock less the payment described in clause (iv).

(f) If a subsidiary of Master LLC that is treated as a corporation for federal income tax purposes remits a payment to Parent pursuant to Section 7.09(d)(ii) or 7.09(e) in respect of Tax Benefits relating to a Compensation Deduction (each such payment is a “Tax Benefit Payment”) and if any such Tax Benefit has been disallowed (in whole or in part) by a Governmental Authority, then Parent shall remit to the appropriate subsidiary the amount of the disallowed Tax Benefit, together with any additional amount to reimburse such subsidiary for any interest imposed by the Governmental Authority. If any such Tax Benefit Payment is required to be treated as a distribution under Section 301 of the Code by such subsidiary, then

any income or gain recognized on account of such distribution shall be specially allocated to the Parent Members (pro rata in proportion to their respective number of Units) and Parent and the Parent Members shall indemnify and hold harmless the Purchaser and its Affiliates from any Taxes related to such income or gain.

(a) From and after the Closing, Master LLC shall be indemnified and held harmless by Parent for and against all losses, damages, claims, costs and expenses, interest, diminution in value from the enterprise value of Master LLC and its Subsidiaries, taken as a whole, awards, judgments and penalties (including reasonable attorneys’ fees and expenses, but excluding any allocation of corporate overhead, internal legal department costs and other internal costs and expenses) suffered or incurred by it (hereinafter, “Losses”), arising out of or resulting from: (i) the breach of any representation or warranty made by Parent contained in this Agreement (other than the representations and warranties contained in Section 3.03(a)) or in the certificate delivered pursuant to Section 2.11(e); (ii) the breach of any (A) pre-Closing covenant or agreement by Parent, Holdco 1, Holdco 2, Master LLC or Medifax contained in this Agreement or (B) post-Closing covenant or agreement by Parent, Holdco 1 or Holdco 2 contained in this Agreement; (iii) any Excluded Liability; or (iv) the Retained Claims. For purposes of determining whether there has been a breach and the amount of any Losses that are the subject matter of a claim for indemnification under this Article IX, except with respect to the representations and warranties in Sections 3.07 and 3.09(n), each representation or warranty contained in this Agreement (and the certificate delivered pursuant to Section 2.11(e)) shall be read without regard and without giving effect to any materiality or

Material Adverse Effect standard or qualification contained in such representation or warranty (as if such standard or qualification were deleted from such representation and warranty), except that specific dollar thresholds in such standard or qualification shall be regarded and given effect with respect to information required to be listed in the Disclosure Schedule.

(b) The Purchaser shall be indemnified and held harmless by Parent for and against all Losses arising out of or resulting from the breach of the representations and warranties made by Parent contained in Section 3.03(a) and in the certificate delivered pursuant to Section 2.11(e) as it relates to the representations and warranties made by Parent in Section 3.03(a).

Section 9.03 Indemnification by the Purchaser. From and after the Closing, Parent shall be indemnified and held harmless by the Purchaser for and against any and all Losses, arising out of or resulting from: (i) the breach of any representation or warranty made by the Purchaser contained in this Agreement; or (ii) the breach of any (A) pre-Closing covenant or agreement by the Purchaser, Merger LLC or Merger Co contained in this Agreement or (B) post-Closing covenant or agreement by the Purchaser contained in this Agreement.

Section 9.04 Limits on Indemnification. (a) No claim may be asserted nor may any Action be commenced against either party for breach of any representation or warranty contained herein, unless written notice of such claim or action is received by such party describing in reasonable detail the facts and circumstances with respect to the subject matter of such claim or Action on or prior to the date on which the representation or warranty on which such claim or Action is based ceases to survive as set forth in Section 9.01.

(b) Notwithstanding the foregoing, except as provided in the immediately following sentence: (i) an Indemnifying Party shall not be liable for any claim for indemnification pursuant to Section 9.02(a)(i) or Section 9.03(i), unless and until the aggregate amount of indemnifiable Losses which may be recovered from the Indemnifying Party equals or exceeds $10,000,000 after which the Indemnifying Party shall be liable only for those Losses in excess of such amount; (ii) no Losses may be claimed under Section 9.02(a)(i) or Section 9.03(i) by an Indemnified Party, or shall be reimbursable by an Indemnifying Party, or shall be included in calculating the aggregate Losses set forth in clause (i) above, other than Losses in excess of $50,000 resulting from any single claim or aggregated claims arising out of the same facts, events or circumstances (in which case the full amount of such Loss shall be recoverable), (iii) the maximum amount of indemnifiable Losses which may be recovered from an Indemnifying Party arising out of or resulting from the causes set forth in Section 9.02(a)(i) or Section 9.03(i) and shall be an amount equal to $150,000,000; (iv) neither party shall have any liability under any provision of this Agreement or the Transition Services Agreement for any punitive, incidental, consequential, special or indirect damages, including speculative, unforeseeable, exemplary damages or lost profits unless such damages are suffered or incurred pursuant to a Third-Party Claim (it being understood that this clause (iv) is not intended to be construed to limit the inclusion of a diminution in value in the definition of “Loss”) and (v) no Losses may be claimed under Section 9.02 or Section 9.03 by any Indemnified Party to the extent the amount of such Loss was reflected in Current Liabilities in Closing Net Working Capital. Notwithstanding any limitations in the immediately preceding sentence of this Section 9.04(b), from and after the Closing, an Indemnifying Party shall indemnify, defend and hold harmless any Indemnified

Party from and against 100% of all Losses suffered or incurred by any such Indemnified Party to the extent resulting from a breach of a Fundamental Rep. The limitations set forth in this Section 9.04 shall not apply with respect to any claim for indemnification arising from or relating to any breach of any of the representations or warranties set forth in Section 3.16 to the extent such breach results in a Loss for which Parent is responsible pursuant to Section 7.01(a).

(c) For all purposes of this Article IX, (i) “Losses” shall be net of any insurance, indemnification or other recoveries actually paid to the Indemnified Party or its Affiliates under any insurance policy (net of any increase in premiums required to be paid as a result of such Loss) or any other Contract in connection with the facts giving rise to the right of indemnification and (ii) any Tax Benefit actually realized by the Indemnified Party (and, in the case of Master LLC, and its Members) in a taxable period (or portion thereof) beginning after the Closing Date as a result of the accrual, incurrence or payment of any such Losses shall be taken into account in a manner consistent with Section 7.02(b) (including the special allocation of deductions to the Indemnifying Party, if applicable).

Section 9.05 Notice of Loss; Third-Party Claims; Retained Claims. (a) An Indemnified Party shall give the Indemnifying Party notice (a “Claims Notice”) of any matter which an Indemnified Party has determined has given or could give rise to a right of indemnification under this Agreement, within 30 days of such determination, stating the amount of the Loss, if known, and method of computation thereof, and containing a reference to the provisions of this Agreement in respect of which such right of indemnification is claimed or arises. Failure to deliver a Claims Notice with respect to a claim in a timely manner as specified in the preceding sentence or failure to deliver timely notice of a Third-Party Claim as contemplated by Section 9.05(b) shall not affect the Indemnified Party’s right to indemnification hereunder for Losses in connection with such claim, but the amount of indemnification to which the Indemnified Party is entitled shall be reduced by the amount, if any, by which the Indemnified Party’s Losses would have been materially less had such notice been timely delivered.

(b) If an Indemnified Party shall receive notice of any Action, audit, claim, demand or assessment (each, a “Third-Party Claim”) against it which may give rise to a claim for Loss under this Article IX, within 30 days of the receipt of such notice, the Indemnified Party shall give the Indemnifying Party notice of such Third-Party Claim. The Indemnifying Party shall be entitled to assume and control the defense of such Third-Party Claim at its expense and through counsel of its choice if it gives notice of its intention to do so to the Indemnified Party within 15 days of the receipt of such notice from the Indemnified Party. If the Indemnifying Party elects to undertake any such defense against a Third-Party Claim, the Indemnified Party may participate in such defense at its own expense. The Indemnified Party shall cooperate with the Indemnifying Party in such defense and make available to the Indemnifying Party, at the Indemnifying Party’s expense, all witnesses, pertinent records, materials and information in the Indemnified Party’s possession or under the Indemnified Party’s control relating thereto as is reasonably requested by the Indemnifying Party. If the Indemnifying Party elects to direct the defense of any such claim or proceeding, the Indemnified Party shall not make any payment toward a settlement of such claim, nor permit to be paid any monies as part of a settlement, unless the Indemnifying Party consents in writing (which consent shall not be unreasonably withheld) to such payment or unless the Indemnifying Party withdraws from the defense of such

Third-Party Claim. If the Indemnifying Party declines to direct the defense of any such claims or proceeding pursuant to this Section 9.05 and the Indemnified Party proposes to settle such claims or proceeding prior to a final judgment thereon or to forgo any appeal with respect thereto, then the Indemnified Party shall give the Indemnifying Party prompt written notice thereof and the Indemnifying Party shall have the right to participate, at its own expense, in the settlement or assume or reassume the defense of such claims or proceeding.

(c) Control of Action, Defense and Settlement. Parent shall have the unrestricted right to control, defend and/or settle any Action in respect of a Retained Claim, commence any future Action on behalf of the Companies and control, defend and/or settle any such future Action relating to a Retained Claim, and shall have the right to employ its own counsel in connection therewith. Master LLC shall also have the right to be represented by separate counsel at Parent’s expense in connection with any such Action in respect of a Retained Claim. Master LLC acknowledges and agrees that Parent shall at all times retain exclusive control over all negotiations with respect to such Actions and final authority to settle any and/or all issues related to the Retained Claims; except with respect to any settlement agreement that contains a sanction or restriction upon the conduct of any business by Master LLC or the Companies.

Section 9.06 Remedies. (a) The parties to this Agreement acknowledge and agree that they are not entitled to rely on any representations or warranties or other statements of fact or opinion, other than the representations and warranties expressly set forth in this Agreement (including the Disclosure Schedule). The parties to this Agreement also acknowledge and agree that, except in the case of fraud or intentional misrepresentation (i) following the Closing, the indemnification provisions of Section 9.02 and Section 9.03 shall be the sole and exclusive remedies of the parties for any breach by the other parties of the representations and warranties in this Agreement and for any failure by the other parties to perform and comply with any covenants and agreements in this Agreement, except that if any of the provisions of this Agreement are not performed in accordance with their terms or are otherwise breached, the Purchaser shall be entitled to specific performance of the terms thereof in addition to any other remedy at law or equity and (ii) anything herein to the contrary notwithstanding, no breach of any representation, warranty, covenant or agreement contained herein shall give rise to any right on the part of any party hereto, after the consummation of the Mergers, to rescind this Agreement or any of the transactions contemplated by this Agreement. Each party shall use commercially reasonable efforts to mitigate its Losses (including, to the extent consistent with sound business judgment, incurring costs only to the minimum extent necessary to remedy the breach which gives rise to the Losses) upon becoming aware of any event which would reasonably be expected to, or does, give rise thereto. In furtherance and not in limitation of the foregoing, in the event any Losses are recoverable under insurance policies or other collateral sources, the parties shall, if commercially reasonable, pursue recovery of such Losses under such insurance policies or other collateral sources (it being understood that no party hereto shall be required to initiate litigation in order to pursue such recovery); provided, that in the event any amounts recovered or recoverable under insurance policies or other collateral sources are not received before any claim for indemnification is paid pursuant to Section 9.03, then Master LLC shall pursue such insurance policies or collateral sources, and in the event Master LLC receives any recovery, the amount of such recovery shall be applied to refund any payments made by Parent which would not have been so paid had such recovery been obtained

prior to such payment. Notwithstanding anything to the contrary, the Investor Guaranty shall be the sole and exclusive remedy for any breach or violation by the Purchaser of this Agreement and in no event will the Purchaser or any of its Affiliates have any liability in excess of the amount provided for in the Investor Guaranty either prior to or following a termination of this Agreement or will Parent be entitled to specific performance or any other equitable remedy.

(b) In connection with the Purchaser’s investigation of the Companies, the Purchaser has received certain estimates, projections, forecasts, plans, budgets and similar forward-looking statements, materials and information regarding or relating to such materials, and the Purchaser and Merger LLC acknowledge and agree that no representation or warranty is being made by or on behalf of Parent with respect to such materials. Following the Closing, for purposes of the indemnification provided for in this Article IX, Master LLC agrees that all the acknowledgements and agreements contained in this Section 9.06(b) shall apply to Master LLC in its capacity as an Indemnified Party as if expressly made by it herein.

Section 9.07 Tax Matters. Anything in this Article IX to the contrary notwithstanding, the rights and obligations of the parties with respect to indemnification for any and all Tax matters other than any breach or inaccuracy of the representations and warranties in Section 3.15 (to the extent such representations and warranties cover Tax matters) or Section 3.16, which breaches shall be covered by this Article IX except as provided in the next sentence) shall be solely governed by Article VII and shall not be subject to the provisions of this Article IX. Notwithstanding anything to the contrary, matters relating to a breach of Section 3.16 shall not be subject to Section 9.05, but rather shall be governed by Article VII.

Section 9.08 Treatment of Indemnification Payments. The parties shall treat for all income Tax purposes any indemnification payment made in accordance with this Article IX (i) that is paid to the Purchaser by Parent or by Parent to the Purchaser, as an adjustment to the LLC Cash Merger Consideration, and (ii) that is paid to or by Master LLC, as an adjustment to the net fair market value of Master LLC as of the Closing Date.

(c) by either the Purchaser or Parent in the event that any Governmental Order restraining, enjoining or otherwise prohibiting the transactions contemplated by this Agreement shall have become final and nonappealable;

(d) by the Purchaser if Parent, Holdco 1, Holdco 2, Master LLC or Medifax shall have breached any of its representations, warranties, covenants or agreements contained in this Agreement, which would give rise to the failure of a condition set forth in Article VIII, which breach cannot be or has not been cured by the Termination Date as may be extended pursuant to Section 10.01(b);

(e) by Parent, if the Purchaser, Merger LLC or Merger Co shall have breached any of its representations, warranties, covenants or agreements contained in this Agreement which would give rise to the failure of a condition set forth in Article VIII; or

Section 11.03 Severability. If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any Law or public policy, all other terms and provisions of this Agreement shall nevertheless remain in full force and effect for so long as the economic or legal substance of the transactions contemplated by this Agreement is not affected in any manner materially adverse to either party hereto. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in an acceptable manner in order that the transactions contemplated by this Agreement are consummated as originally contemplated to the greatest extent possible.

Section 11.04 Entire Agreement. This Agreement (including the Disclosure Schedule and all Exhibits hereto), the Transition Services Agreement, the LLC Agreement, the Trademark Assignment Agreement, the Investor Guaranty and the Confidentiality Agreement constitute the entire agreement of the parties hereto with respect to the subject matter hereof and thereof and supersede all prior agreements and undertakings, both written and oral, between any of the parties hereto with respect to the subject matter hereof and thereof.

Section 11.05 Assignment. (a) Subject to paragraph (b), this Agreement may not be assigned by operation of law or otherwise without the express written consent of Parent and the Purchaser (which consent may be granted or withheld in the sole discretion of Parent or the Purchaser, as the case may be).

(b) Without the written consent of any party hereto, (i) the Purchaser may assign its rights and obligations to any of its Affiliates and (ii) the Purchaser may assign its rights hereunder as collateral security to any lender to a Company, but no such assignment described in clause (i) or (ii) shall relieve the Purchaser of any liability hereunder.

Section 11.06 Amendment. This Agreement may not be amended or modified except (a) by an instrument in writing signed by, or on behalf of, the parties hereto or (b) by a waiver in accordance with Section 11.07.

Section 11.07 Waiver. Each party to this Agreement may (a) extend the time for the performance of any of the obligations or other acts of the other parties, (b) waive any inaccuracies in the representations and warranties of the other parties contained herein or in any document delivered by the other such party pursuant hereto or (c) waive compliance with any of the agreements of the other parties or conditions to such parties’ obligations contained herein. Any such extension or waiver shall be valid only if set forth in an instrument in writing signed by the party to be bound thereby. Any waiver of any term or condition shall not be construed as a waiver of any subsequent breach or a subsequent waiver of the same term or condition, or a waiver of any other term or condition of this Agreement. The failure of any party hereto to assert any of its rights hereunder shall not constitute a waiver of any of such rights.

Section 11.08 Schedules. Any matter, information or item disclosed in the Disclosure Schedule, under any specific representation or warranty or schedule number hereof, shall be deemed to have been disclosed for all purposes of this Agreement in response to every representation or warranty in this Agreement in respect of which such disclosure is reasonably apparent. The inclusion of any matter, information or item in the Disclosure Schedule shall not be deemed to constitute an admission of any liability by Parent, Master LLC or any Company to any third party or otherwise imply that any such matter, information or item is material or creates a measure for materiality or Material Adverse Effect for the purposes of this Agreement.

Section 11.09 No Third Party Beneficiaries. This Agreement shall be binding upon and inure solely to the benefit of the parties hereto and their respective successors and permitted assigns and nothing herein, express or implied (including the provisions of Article IX relating to indemnified parties), is intended to or shall confer upon any other Person any legal or equitable right, benefit or remedy of any nature whatsoever, including any rights of employment for any specified period, under or by reason of this Agreement.

All Actions arising out of or relating to this Agreement shall be heard and determined exclusively in any New York federal court sitting in the Borough of Manhattan of The City of New York; provided, however, that if such federal court does not have jurisdiction over such Action, such Action shall be heard and determined exclusively in any New York state court sitting in the Borough of Manhattan of The City of New York.

execution, that the Action is brought in an inconvenient forum, that the venue of the Action is improper, or that this Agreement or the transactions contemplated by this Agreement may not be enforced in or by any of the above-named courts.
