SECTION 4. Allocation of Taxes.

(a) General Allocation Principles. Except as provided in Section 4(c), all Taxes shall be allocated as follows:

(i) Allocation of Taxes for Combined Tax Returns. Parent shall be allocated all Taxes reported, or required to be reported, on any Combined Tax Return that any member of the Parent Group files or is required to file under the Code or other Applicable Tax Law; provided, however, that (A) to the extent any such Combined Tax Return includes any Tax Item attributable to any member of the SpinCo Group or the Controlled Business in respect of any Post-Distribution Period, SpinCo shall be allocated all Taxes attributable to such Tax Items and (B) to the extent any such Combined Tax Return includes any Tax Item in respect of any Pre-Distribution Period, SpinCo shall be allocated such Taxes to the extent a member of the SpinCo Group is (or, but for an amendment to, or waiver under, the LLC Agreement occurring after the Distribution, would be) entitled to a Covered Tax Distribution (for the avoidance of doubt, other than a Covered Tax Distribution that has already been made) in respect of the Tax Items giving rise to such Taxes.

(ii) Allocation of Taxes for Separate Tax Returns.

(A) Except for Taxes allocated to SpinCo pursuant to Section 4(a)(ii)(B), Parent shall be allocated all Taxes reported, or required to be reported, on a Parent Separate Tax Return or a SpinCo Separate Tax Return.

(B) SpinCo shall be allocated all Taxes reported, or required to be reported, on (x) a Parent Separate Tax Return with respect to a Pre-Distribution Period to the extent a member of the SpinCo Group is (or would be) entitled to a Covered Tax Distribution (for the avoidance of doubt, other than a Covered Tax Distribution that has already been made) in respect of the Tax Item(s) giving rise to such Taxes, (y) a SpinCo Separate Tax Return (including, for the avoidance of doubt, a SpinCo Separate Tax Return filed or required to be filed in respect of federal, state, local or foreign income Taxes on an affiliated, consolidated, combined, unitary, fiscal unity or other group basis (including as permitted by Section 1501 of the Code) with any member of the Acquiror Group) with respect to a Post-Distribution Period or (z) a SpinCo Separate Tax Return with respect to a Pre-Distribution Period, but in the case of this clause (z), only to the extent a

13

member of the SpinCo Group is (or, but for an amendment to, or waiver under, the LLC Agreement occurring after the Distribution, would be) entitled to a Covered Tax Distribution (for the avoidance of doubt, other than a Covered Tax Distribution that has already been made) in respect of the Tax Item(s) giving rise to such Taxes.

(b) Allocation Conventions.

(i) All Taxes allocated pursuant to Section 4(a) shall be allocated in accordance with the Closing of the Books Method; provided, however, that if Applicable Tax Law does not permit a SpinCo Group member to close its Taxable year on the Distribution Date, the Tax attributable to the operations of the members of the SpinCo Group for any Pre-Distribution Period shall be the Tax computed using a hypothetical closing of the books consistent with the Closing of the Books Method.

(ii) Any Tax Item of SpinCo, Acquiror or any member of their respective Groups arising from a transaction engaged in outside the ordinary course of business on the Distribution Date after the Distribution Effective Time shall be properly allocable to SpinCo and any such transaction by or with respect to SpinCo, Acquiror or any member of their respective Groups occurring after the Distribution Effective Time shall be treated for all Tax purposes (to the extent permitted by Applicable Tax Law) as occurring at the beginning of the day following the Distribution Date in accordance with the principles of Treasury regulations Section 1.1502-76(b) (assuming no election is made under Section 1.1502-76(b)(2)(ii) of the Treasury regulations (relating to a ratable allocation of a year’s Tax Items)); provided that the foregoing shall not include any action that is undertaken pursuant to the Internal Restructuring, the Controlled Transfer, the Distribution, the Merger or the Transaction Documents.

(c) Special Allocation Rules. Notwithstanding any other provision in this Section 4, the following Taxes shall be allocated as follows:

(i) Transfer Taxes. Transfer Taxes (other than those attributable to the Internal Restructuring) shall be allocated to SpinCo. Any Transfer Taxes attributable to the Internal Restructuring shall be allocated to Parent.

(ii) JV Group Taxes. JV Group Taxes shall be allocated to (A) SpinCo, if paid by a member of the Parent Group pursuant to Section 5(g) and (B) the JV, otherwise.

(iii) Distribution Taxes and Tax-Related Losses.

(A) Any liability for Distribution Taxes (and any associated Tax-Related Losses) which would not have been incurred but for one or more Echo Disqualifying Actions (as determined by treating any acquisition of capital stock of Parent, SpinCo or Acquiror that constitutes a Parent Disqualifying Action as if such acquisition did not occur) shall be allocated to SpinCo, subject to Section 4(c)(iii)(B) and Section 4(c)(iii)(C).

14

(B) Any liability for Distribution Taxes (and any associated Tax-Related Losses) solely by reason of the application of Section 355(e) which would not have been incurred if, instead of the occurrence of one or more Debt Exchanges that exceeds the MCK Cushion Amount, 100% of the SpinCo Common Stock had been distributed in a Split-Off Exchange or Spin-Off on the Distribution Date to Persons whose acquisitions of such SpinCo Common Stock were disregarded by reason of Section 355(e)(3)(A) of the Code, shall be allocated to Parent.

(C) Any liability for Distribution Taxes (and any associated Tax-Related Losses) not described in Section 4(c)(iii)(B) which (x) would not have been incurred but for the occurrence of both one or more Echo Disqualifying Actions and one or more Parent Disqualifying Actions, or which (y) both (I) would not have been incurred but for the occurrence of one or more Echo Disqualifying Actions (as determined by treating any Parent Disqualifying Actions as if such Parent Disqualifying Actions did not occur) and (II) would not have been incurred but for the incurrence of one or more Parent Disqualifying Actions (as determined by treating any Echo Disqualifying Actions as if such Echo Disqualifying Actions did not occur), shall be allocated to Parent.

(D) Any liability for Distribution Taxes (and any associated Tax-Related Losses) not described in Section 4(c)(iii)(A), Section 4(c)(iii)(B) or Section 4(c)(iii)(C) shall be allocated to Parent.

(iv) Internal Restructuring Taxes. Notwithstanding any other provision in this Section 4, all Taxes with respect to the Internal Restructuring shall be allocated to Parent, except that any Taxes with respect to the Internal Restructuring to the extent attributable to the failure by the SpinCo Group to preserve the Intended Tax-Free Treatment of the transaction described in clause (iv) of the definition of Intended Tax-Free Treatment, as a result of (a) the failure of the SpinCo Group after the Effective Time to continue the historic business of the SpinCo Group or use a significant portion of the SpinCo Group’s business assets in a business, except as a result of any action that any member of the SpinCo Group was, beginning at any time prior to the Effective Time, contractually bound to take (including pursuant to any Transaction Document or Exit Transaction Document), (b) the breach of the representations and covenants of the Acquiror Group contained in this Agreement or (c) the breach of the covenants contained in this Agreement after the Effective Time by any member of the SpinCo Group, in each case, shall be allocated to SpinCo.

With respect to any Tax Return that Acquiror has the obligation and right to prepare, or cause to be prepared, under this Section 5 (other than a SpinCo Separate Tax Return that relates solely to a Post-Distribution Period and/or to JV Group Taxes), except as otherwise required by law or with the consent of Parent (such consent not to be unreasonably withheld, conditioned, or delayed), such Tax Return shall be prepared in accordance with Past Practices used by the members of the Parent Group and the members of the SpinCo Group (or, in the case of a JV Income Tax Return, JV) prior to the Distribution Date with respect to such Tax Return, and, with respect to any such Tax Return other than a JV Income Tax Return, to the extent any items, methods or positions are not covered by Past Practices, in accordance with reasonable Tax accounting practices selected by Acquiror.

17

(ii) Consistency with Intended Tax-Free Treatment.

(A) The parties shall report the Internal Restructuring in the manner determined by Parent; provided that (x) Parent communicates its treatment of the Internal Restructuring to Acquiror no fewer than thirty (30) days prior to the due date (taking into account any applicable extensions) for filing an applicable Tax Return that reflects the Internal Restructuring (y) such treatment is supported by substantial authority (within the meaning of Section 6662 of the Code), as determined by Acquiror in its reasonable discretion, in each case, unless, and then only to the extent, an alternative position is required pursuant to a Final Determination, and (z) a member of the Acquiror Group may book reserves or make disclosures relating to the Internal Restructuring if required to do so under applicable accounting principles or Tax law.

(B) The parties shall report the Controlled Transfer, the Distribution and the Merger for all Tax purposes in a manner consistent with the Intended Tax-Free Treatment unless, and then only to the extent, an alternative position is required pursuant to a Final Determination.

(iii) SpinCo Separate Tax Returns. With respect to any SpinCo Separate Tax Return for which Acquiror is responsible pursuant to this Agreement, Acquiror and the other members of the Acquiror Group shall include such Tax Items in such SpinCo Separate Tax Return in a manner that is consistent with the inclusion of such Tax Items in any related Tax Return for which Parent is responsible to the extent such Tax Items are allocated in accordance with this Agreement.

(iv) Election to File Combined Tax Returns. Parent shall have sole discretion to file any Combined Tax Return if the filing of such Tax Return is elective under Applicable Tax Law.

(v) Preparation of Transfer Tax Returns. The Company required under Applicable Tax Law to file any Tax Returns in respect of Transfer Taxes shall prepare and file (or cause to be prepared and filed) such Tax Returns. If required by Applicable Tax Law, Parent, SpinCo and Acquiror shall, and shall cause their respective Subsidiaries to, cooperate in preparing and filing, and join the execution of, any such Tax Returns.

Parent shall pay (or cause to be paid) to the proper Taxing Authority (or to Acquiror with respect to any SpinCo Separate Tax Return prepared by Parent but required to be filed by a member of the Acquiror Group under Applicable Tax Law) the Tax shown as due on any Tax Return for which a member of the Parent Group is responsible under this Section 5, and the members of the JV Group shall be jointly and severally liable to pay to Acquiror, and Acquiror shall pay (or cause to be paid) to the proper Taxing Authority the Tax shown as due on any Tax Return for which a member of the Acquiror Group is responsible under this Section 5.

SECTION 6. Apportionment of Earnings and Profits and Tax Attributes.

(a) Tax Attributes arising in a Pre-Distribution Period will be allocated to (and the benefits and burdens of such Tax Attributes will inure to) the members of the Parent Group and the members of the SpinCo Group in accordance with the Code, Treasury regulations and any other Applicable Tax Law, and, in the absence of controlling legal authority or unless otherwise provided under this Agreement, Tax Attributes shall be allocated to the legal entity that created such Tax Attributes.

(b) On or before the earlier of (i) eighteen (18) months after the Distribution Date or (ii) sixty (60) days prior to the extended due date for the first U.S. federal income Tax Return of the Acquiror Group following the Distribution Date, Parent shall deliver to Acquiror its determination in writing of the portion, if any, of any earnings and profits, Tax Attributes, overall foreign loss or other affiliated, consolidated, combined, unitary, fiscal unity or other group basis Tax Attribute which is allocated or apportioned to the members of the SpinCo Group under Applicable Tax Law and this Agreement (“Proposed Allocation”). Acquiror shall have forty-five (45) days to review the Proposed Allocation and provide Parent any comments with respect thereto, and Parent agrees to consider such comments in good faith. If Acquiror either provides no comments or provides comments to which Parent agrees in writing, such resulting determination will become final (“Final Allocation”). If Acquiror provides comments to the Proposed Allocation and Parent does not agree with such comments, the Final Allocation will be determined in accordance with Section 24. All members of the Parent Group and Acquiror Group shall prepare all Tax Returns in accordance with the Final Allocation. In the event of an adjustment to the earnings and profits, any Tax Attributes, overall foreign loss or other affiliated, consolidated, combined, unitary, fiscal unity or other group basis Tax Attribute, Parent shall promptly notify Acquiror in writing of such adjustment. For the avoidance of doubt, Parent shall not be liable to any member of the Acquiror Group for any failure of any determination under this Section 6(b) to be accurate under Applicable Tax Law; provided that such determination was made in good faith.

(c) Except as otherwise provided herein, to the extent that the amount of any Tax Attribute is later reduced or increased by a Taxing Authority or as a result of a Tax Proceeding, such reduction or increase shall be allocated to the Company to which such Tax Attribute was allocated pursuant to this Section 6, as agreed by the parties.

SECTION 7. Utilization of Tax Attributes.

(a) Amended Returns. Any amended Tax Return or claim for a refund with respect to any member of the SpinCo Group may be made only by the party responsible for preparing the original Tax Return with respect to such member of the SpinCo Group pursuant to Section 5. Such party shall not file or cause to be filed any such amended Tax Return or claim for a refund without the prior written consent of the other party, which consent shall not be unreasonably withheld, conditioned or delayed, if such filing, assuming it is accepted, could reasonably be expected to change the Tax liability of such other party (or any Affiliate of such other party) for any Taxable period (including, for the avoidance of doubt, the amount of any Tax Attributes allocable under Section 6 to such other party (or any Affiliate of such other party)).

19

(b) Carryback of Tax Attributes.

(i) To the extent permitted by Applicable Tax Law, Acquiror shall cause the SpinCo Group to elect to forego carrybacks of any Tax Attributes of the SpinCo Group to a Pre-Distribution Period.

(ii) If Acquiror is unable to forego carrybacks of any Tax Attributes of the SpinCo Group to a Pre-Distribution Period, the Parent Group shall, at the request of Acquiror and at Acquiror’s sole expense, file any amended Tax Returns reflecting such carryback (unless such filing, assuming it is accepted, could reasonably be expected to increase by more than a de minimis amount, the Tax liability of Parent or any of its Affiliates for any Taxable period). If the Parent Group (or any member thereof) receives (or realizes) a refund as a result of such a carryback, Parent shall promptly remit the amount of such refund to Acquiror in accordance with Section 8(b).

(c) Carryforwards to Separate Tax Returns. If a portion or all of any Tax Attribute is allocated to a member of a Combined Group pursuant to Section 6, and is carried forward to a SpinCo Separate Tax Return, any Tax Benefits arising from such carryforward shall be retained by the Acquiror Group. If a portion or all of any Tax Attribute is allocated to a member of a Combined Group pursuant to Section 6, and is carried forward to a Parent Separate Tax Return, any Tax Benefits arising from such carryforward shall be retained by the Parent Group.

SECTION 8. Tax Benefits.

(a) Parent Tax Benefits. Parent shall be entitled to any Tax Benefits (including, in the case of any refund received, any interest thereon actually received) received by any member of the Parent Group or any member of the SpinCo Group, other than any Tax Benefits (or any amounts in respect of Tax Benefits) to which SpinCo or Acquiror is entitled pursuant to Section 8(b). Neither SpinCo nor Acquiror shall be entitled to any Tax Benefits received by any member of the Parent Group or the SpinCo Group, except as set forth in Section 8(b).

(b) SpinCo and Acquiror Tax Benefits. SpinCo or Acquiror, as the case may be, shall be entitled to any Tax Benefits (including, in the case of any refund received, any interest thereon actually received) received (i) by any member of the Parent Group or any member of the SpinCo Group after the Distribution Date with respect to any Tax allocated to the JV or a member of the SpinCo Group under this Agreement (including, for the avoidance of doubt, any amounts allocated to the JV pursuant to Section 4(c)(iii)), or (ii) by a member of the SpinCo Group in respect of a Post-Distribution Period.

(c) A Company receiving (or realizing) a Tax Benefit (a “Tax Benefit Recipient”) to which another Company is entitled hereunder shall pay over the amount of such Tax Benefit (including interest received from the relevant Taxing Authority, but net of any Taxes imposed with respect to such Tax Benefit and any other reasonable costs) within thirty (30) days of receipt thereof (or from the due date for payment of any Tax reduced thereby); provided, however, that the other Company, upon the request of such Tax Benefit Recipient, shall repay the amount paid to the other Company (plus any penalties, interest or other charges imposed by the relevant Taxing Authority) in the event that, as a result of a subsequent Final Determination, a Tax Benefit that gave rise to such payment is subsequently disallowed.

24

(F) no member of the Acquiror Group will amend its certificate of incorporation (or other organizational documents), or take any other action, whether through a stockholder vote or otherwise, affecting the voting rights of the Equity Interests of SpinCo or Acquiror (including, without limitation, through the conversion of one class of Equity Interests of SpinCo or Acquiror into another class of Equity Interests of SpinCo or Acquiror); and

(G) no member of the Acquiror Group will take, or permit to be taken, any action, whether by merger, liquidation, the making of an entity classification election or otherwise, that would result in JV ceasing to be treated as a partnership for U.S. federal income tax purposes.

25

(iv) in the case of any other action that would reasonably be expected to be inconsistent with the covenants contained in (b), if either: (A) SpinCo or Acquiror notifies Parent of its proposal to take such action and Acquiror and Parent obtain a ruling from the IRS to the effect that such action will not affect the Intended Tax-Free Treatment (a “Favorable Tax Ruling”), provided that Acquiror agrees in writing to bear any expenses associated with obtaining such a ruling and, provided further that the Acquiror Group shall not be relieved of any liability under Section 12(a) of this Agreement by reason of seeking or having obtained such a ruling; or (B) SpinCo or Acquiror notifies Parent of its proposal to take such action and obtains an unqualified opinion of counsel or from a “Big Four” accounting firm (x) from a Tax advisor recognized as an expert in federal income Tax matters and reasonably acceptable to Parent, (y) on which Parent may rely and (z) to the effect that such action will not affect the Intended Tax-Free Treatment (assuming that the Internal Restructuring, the Controlled Transfer, the Distribution and the Merger would otherwise qualify for the Intended Tax-Free Treatment) (a “Favorable Tax Opinion”), provided further that the Acquiror Group shall not be relieved of any liability under Section 12(a) of this Agreement by reason of having obtained a Favorable Tax Opinion.

SECTION 10. Procedures Relating to Opinions and Rulings. If a member of the Acquiror Group notifies Parent that it desires to take an action that would reasonably be expected to be inconsistent with the covenants contained in Section 9(b), then the Parent Group shall cooperate in good faith with the Acquiror Group to obtain the Favorable Tax Ruling and/or a Favorable Tax Opinion. The Acquiror Group shall reimburse Parent for all reasonable out-of-pocket expenses incurred by the Parent Group in connection with such cooperation within fifteen (15) Business Days of receipt of an invoice from Parent therefor.

SECTION 11. Protective Section 336(e) Elections.

(a) Section 336(e) Election. Pursuant to Treasury regulations Sections 1.336-2(h)(1)(i) and 1.336-2(j), Parent, Acquiror and SpinCo agree that (if and to the extent determined by Parent) Parent shall make a timely protective election under Section 336(e) of the Code and the Treasury regulations issued thereunder for any member of the SpinCo Group that is a domestic corporation for U.S. federal income Tax purposes with respect to the Distribution (a “Section 336(e) Election”). It is intended that a Section 336(e) Election will have no effect unless the Distribution is a “qualified stock disposition,” as defined in Treasury regulations Section 1.336(e)-1(b)(6), by reason of the application of Treasury regulations Section 1.336-1(b)(5)(i)(B) or Treasury regulations Section 1.336-1(b)(5)(ii).

(b) Parent TRA. If and to the extent that there is a Disqualifying Action and the resulting Taxes (including any Taxes attributable to the Section 336(e) Election) are allocated to Parent pursuant to Section 4, (i) Parent shall be entitled to periodic payments from SpinCo equal to the product of (x) 85% of the tax savings arising from the step-up in tax basis resulting from the Section 336(e) Election and (y) the percentage of such Taxes that are allocated to Parent pursuant to Section 4, and (ii) the Parties shall negotiate in good faith the terms of a tax receivable agreement to govern the calculation of such payments, with it being agreed that the terms of such agreement shall be substantially similar to the terms of the MCK Tax Receivable Agreement; provided that any such tax saving in clause (i) shall be determined using a “with and without” methodology (treating any deductions or amortization attributable to the step-up in tax basis resulting from the Section 336(e) Election as the last items claimed for any taxable year, including after the utilization of any carryforwards).

26

SECTION 12. Indemnities.

(a) Acquiror Indemnity to Parent. The Acquiror as successor to SpinCo shall be obligated to indemnify (and the JV and each other member of the JV Group shall jointly and severally be obligated to pay to Acquiror all amounts necessary to allow Acquiror to indemnify) Parent and the other members of the Parent Group against, and hold them harmless, without duplication, from (i) any payments by Parent of any Tax liability and any associated Tax-Related Losses allocated to SpinCo pursuant to Section 4; provided that, the amount of such indemnity shall be limited to the amount of any payment of Tax or Tax Related Losses required to be made by Parent or any member of the Parent Group and, for the avoidance of doubt, shall be calculated without regard to any harm to Parent or any member of the Parent Group relating to any equity or other interests in Parent or any other member of the Parent Group directly or indirectly in the JV Group or in the Acquiror Group and (ii) notwithstanding any provisions of this Agreement, the Separation Agreement, the Merger Agreement, or otherwise, any Damages arising from or relating to, directly or indirectly, whether by operation of the provisions of this Agreement, the Separation Agreement, the Merger Agreement or otherwise, any failure of the Effective Time to occur immediately following the Distribution Effective Time primarily as a result of any failure by Acquiror to perform its obligation to close the Merger in accordance with the Merger Areement.

(b) Parent Indemnity to Acquiror. Except in the case of any liabilities described in Section 12(a), Parent and each other member of the Parent Group will jointly and severally indemnify Acquiror and the other members of the Acquiror Group against, and hold them harmless, without duplication, from:

(i) any Tax liability and any associated Tax-Related Losses allocated to Parent pursuant to Section 4;

(ii) any Taxes imposed on any member of the SpinCo Group or Acquiror Group under Treasury regulations Section 1.1502-6 (or similar or analogous provision of state, local or foreign law) as a result of any such member being or having been a member of a Combined Group; and

(iii) notwithstanding any provisions of this Agreement, the Separation Agreement, the Merger Agreement, or otherwise, any Damages arising from or relating to, directly or indirectly, whether by operation of the provisions of this Agreement, the Separation Agreement, the Merger Agreement or otherwise, any failure of the Effective Time to occur immediately following the Distribution Effective Time primarily as a result of any failure by MCK or SpinCo to perform its obligation to close the Merger in accordance with the Merger Agreement.

27

(c) Discharge of Indemnity. Acquiror, the JV, Parent and the members of their respective Groups shall discharge their obligations under Section 12(a) or Section 12(b) hereof, respectively, by paying the relevant amount in accordance with Section 13, within 30 Business Days of demand therefor. Any such demand shall include a statement showing the amount due under Section 12(a) or Section 12(b), as the case may be. Notwithstanding the foregoing, if any member of the Acquiror Group or any member of the Parent Group disputes in good faith the fact or the amount of its obligation under Section 12(a) or Section 12(b), then no payment of the amount in dispute shall be required until any such good faith dispute is resolved in accordance with Section 24 hereof; provided, however, that any amount not paid within thirty (30) Business Days of demand therefor shall bear interest as provided in Section 14.

(d) Tax Benefits. If an indemnification obligation of any Indemnifying Party under this Section 12 arises in respect of an adjustment that makes allowable to an Indemnitee any Tax Benefit (other than a Tax Benefit resulting from a Section 336(e) Election, which shall be governed exclusively by Section 11) which would not, but for such adjustment, be allowable, then any such indemnification obligation shall be an amount equal to (i) the amount otherwise due but for this Section 12(d) minus (ii) the reduction (attributable to such Tax Benefit) in actual cash Taxes payable by the Indemnitee in the taxable year such indemnification obligation arises and the two taxable years following such year, determined on a “with and without” basis.

(e) Sole Remedy. Parent (on behalf of itself and each member of the Parent Group) covenants and agrees that the remedies provided for in Section 12(a) shall constitute the sole and exclusive remedy for all Damages, including any Tax liabilities and any associated Tax-Related Losses, that Parent or any member of the Parent Group may suffer or incur arising from, or directly or indirectly relating to any breach or violation of any of the representations, warranties, covenants and agreements contained in this Agreement, the various Tax Representation Letters, under Section 11.04(e) of the LLC Agreement, or Section 5.15 of the Contribution Agreement by the Acquiror, the JV, SpinCo, and any member of the Acquiror Group, JV Group or SpinCo Group, or otherwise relating to the failure of the Controlled Transfer, the Distribution, or the Merger to occur or receive the Intended Tax-Free Treatment, and the Parent (on behalf of itself and each member of the Parent Group) hereby irrevocably waives any other rights or remedies (whether at law or in equity and whether based on contract, tort, statute or otherwise) that it may otherwise have had, now have or may in the future have against the Acquiror, the JV, SpinCo, and any member of the Acquiror Group, JV Group or SpinCo Group or any of their respective direct or indirect Affiliates, officers, managers, directors, employees, advisors, stockholders, members, consultants, investment bankers, brokers, controlling persons, partners or other representatives or agents thereof arising from, or directly or indirectly relating to any breach or violation of any of the representations, warranties, covenants and agreements contained in this Agreement, the various Tax Representation Letters, under Section 11.04(e) of the LLC Agreement, or Section 5.15 of the Contribution Agreement by the Acquiror, the JV, SpinCo, and any member of the Acquiror Group, JV Group or SpinCo Group and covenants not to sue or otherwise assert any claim (or assist any Person in suing or otherwise asserting any claims) encompassed by the foregoing covenant, agreement and waiver; provided that the foregoing shall not apply to any party’s right to seek specific performance pursuant to Section 20 hereof.

28

SECTION 13. Acquiror Shareholders Not Parties. For the avoidance of doubt, and notwithstanding any provision of this Agreement or any other Transaction Document to the contrary, (i) no Person who is a direct or indirect shareholder, member, or interest holder in Acquiror is a party to, or is bound by, or makes any representations, warranties, or covenants, or indemnities pursuant to, this Agreement (unless such Person is Parent, SpinCo, Acquiror, or any of their respective Subsidiaries), and (ii) notwithstanding that certain Persons described in the foregoing sentence make the representations, warranties, and covenants in the Principal Shareholder Letter, such Persons shall not be liable thereunder, under any Transaction Document, or otherwise by reason of having breached such representations, warranties, or covenants.

SECTION 14. Payments.

(a) Timing. All payments to be made under this Agreement (excluding, for the avoidance of doubt, any payments to a Taxing Authority described herein) shall be made in immediately available funds. Except as otherwise provided, all such payments will be due thirty (30) Business Days after the receipt of notice of such payment or, where no notice is required, thirty (30) Business Days after the fixing of liability or the resolution of a dispute (the “Due Date”). Payments shall be deemed made when received. Any payment that is not made on or before the Due Date shall bear interest at the rate equal to the “prime” rate as published on such Due Date in the Wall Street Journal, Eastern Edition, for the period from and including the date immediately following the Due Date through and including the date of payment. With respect to any payment required to be made under this Agreement, Parent has the right to designate, by written notice to Acquiror, which member of the Parent Group will make or receive such payment; and Acquiror has the right to designate, by written notice to Parent, which member of the Acquiror Group will make or receive such payment.

(b) Treatment of Payments. To the extent permitted by Applicable Tax Law, any payment made by Parent or any member of the Parent Group to Acquiror or any member of the Acquiror Group, or by Acquiror or any member of the Acquiror Group to Parent or any member of the Parent Group, pursuant to this Agreement, the Separation Agreement, the Merger Agreement or any other Exit Transaction Document that relates to Taxable periods (or portions thereof) ending on or before the Distribution Date shall be treated by the parties hereto for all Tax purposes as a distribution by SpinCo to Parent, or capital contribution from Parent to SpinCo, as the case may be; provided, however, that any payment made pursuant to the Transition Services Agreement shall instead be treated as a payment for services. In the event that a Taxing Authority asserts that a party’s treatment of a payment described in this Section 14(b) should be other than as required herein, such party shall use its commercially reasonable efforts to contest such assertion in a manner consistent with Section 16 of this Agreement.

(c) No Duplicative Payment. It is intended that the provisions of this Agreement shall not result in a duplicative payment of any amount required to be paid under the Separation Agreement, the Merger Agreement or any other Exit Transaction Document, and this Agreement shall be construed accordingly.

29

SECTION 15. Communication and Cooperation.

(a) Consult and Cooperate. SpinCo, Parent and Acquiror shall consult and cooperate (and shall cause each other member of their respective Groups to consult and cooperate) fully at such time and to the extent reasonably requested by the other party in connection with all matters subject to this Agreement. Such cooperation shall include, without limitation:

(i) the retention, and provision on reasonable request, of any and all information including all books, records, documentation or other information pertaining to Tax matters relating to the SpinCo Group (or, in the case of any Tax Return of the Parent Group, the portion of such return that relates to Taxes for which the SpinCo Group or the Acquiror Group may be liable pursuant to this Agreement), any necessary explanations of information, and access to personnel, until one year after the expiration of the applicable statute of limitation (giving effect to any extension, waiver or mitigation thereof);

(ii) the execution, to the extent commercially reasonable, of any document that may be necessary (including to give effect to Section 16) or helpful in connection with any required Tax Return or in connection with any audit, proceeding, suit or action; and

(iii) the use of the parties’ commercially reasonable efforts to obtain any documentation from a Governmental Authority or a third party that may be necessary or helpful in connection with the foregoing.

(b) Provide Information. Except as set forth in Section 16, Parent, SpinCo and Acquiror shall keep each other reasonably informed with respect to any material development relating to the matters subject to this Agreement.

(c) Tax Attribute Matters. Parent, SpinCo and Acquiror shall promptly advise each other with respect to any proposed Tax adjustments that are the subject of an audit or investigation, or are the subject of any proceeding or litigation, and that may affect any Tax liability or any Tax Attribute (including, but not limited to, basis in an asset or the amount of earnings and profits) of any member of the Acquiror Group or any member of the Parent Group, respectively.

(d) Confidentiality. The parties hereby agree that the provisions of Section 11.02 (Confidentiality) of the LLC Agreement (as in effect prior to any amendment to, or waiver under, the LLC Agreement occurring after the Distribution) shall apply, mutatis mutandis, to all information and material furnished by any party or its representatives hereunder. Notwithstanding the foregoing or any other provision of this Agreement or any other agreement, (i) no member of the Parent Group or the Acquiror Group, respectively, shall be required to provide any member of the Acquiror Group or the Parent Group, respectively, or any other Person access to or copies of any information or procedures other than information or procedures that relate solely to the SpinCo Group or the JV Group, the business or assets of any member of the SpinCo Group or the JV Group, or matters for which Parent or Acquiror, respectively, has an obligation to indemnify under this Agreement, and (ii) in no event shall any member of the Parent Group or the Acquiror Group, respectively, be required to provide any member of the

30

Acquiror Group or the Parent Group, respectively, or any other Person access to or copies of any information if such action could reasonably be expected to result in the waiver of any privilege. Notwithstanding the foregoing, in the event that Parent or Acquiror, respectively, determines that the provision of any information to any member of the Acquiror Group or the Parent Group, respectively, could be commercially detrimental or violate any law or agreement to which Parent or Acquiror, respectively, is bound, or result in the waiver of any privilege, Parent and Acquiror, respectively, shall use reasonable best efforts to permit compliance with their obligations under this Section 15 while avoiding such harm or consequence (and shall promptly provide notice to Parent or Acquiror, to the extent such access to or copies of any information is provided to a Person other than a member of the Parent Group or the Acquiror Group (as applicable)).

SECTION 16. Audits and Contest.

(a) Notice. Each of Parent, SpinCo and Acquiror shall promptly notify the other parties in writing upon the receipt from a relevant Taxing Authority of any notice of a Tax Proceeding that may give rise to an indemnification obligation under this Agreement; provided that a party’s right to indemnification under this Agreement shall not be limited in any way by a failure to so notify, except to the extent that the Indemnifying Party is prejudiced by such failure.

(b) Parent Control. Notwithstanding anything in this Agreement to the contrary, but subject to Section 16(c), Parent shall have the right to control any Tax Proceeding with respect to any Tax matters of (i) a Combined Group or any member of a Combined Group (as such), (ii) any member of the Parent Group and (iii) any member of the SpinCo Group relating solely to a Pre-Distribution Period (a “Parent Tax Proceeding”). Parent shall have absolute discretion with respect to any decisions to be made, or the nature of any action to be taken, with respect to any Parent Tax Proceeding; provided, however, that to the extent that any Parent Tax Proceeding is reasonably likely to give rise to an indemnity obligation of SpinCo or Acquiror under Section 12 hereof, materially increase the Taxes payable by or allocated to any member of the Acquiror Group pursuant to Section 4 or materially affect the Tax Attributes allocated to any member of the SpinCo Group pursuant to Section 6, (i) Parent shall keep Acquiror informed of all material developments and events relating to any such Parent Tax Proceeding, (ii) at its own cost and expense, Acquiror shall have the right to participate in (but not to control) the defense of any such Parent Tax Proceeding, and (iii) Parent shall not settle or compromise any such contest without Acquiror’s written consent, which consent may not be unreasonably withheld, conditioned or delayed. If the Parent Group acknowledges in writing that it is liable for the Taxes at issue in any Parent Tax Proceeding subject to the proviso in the previous sentence, the rights of Acquiror in such proviso shall not apply to such Parent Tax Proceeding to the extent such Parent Tax Proceeding relates to the Taxes that are the subject of such acknowledgment.

(c) Distribution Taxes. If any Parent Tax Proceeding relating to Distribution Taxes is reasonably likely to give rise to an indemnity obligation of the Acquiror as successor to SpinCo or the JV Group under Section 12 hereof, Acquiror and Parent shall exercise joint control over the disposition of such Parent Tax Proceeding (and, for the avoidance of doubt, shall keep each other informed of all material developments with respect to such Parent Tax Proceeding to the extent the other party is not otherwise informed thereof). Parent shall otherwise have the right to elect to control any Parent Tax Proceeding relating to Distribution Taxes; provided that Parent shall keep Acquiror informed of all material developments.

31

(d) Acquiror Control. Acquiror shall have the right to control any Tax Proceeding with respect to SpinCo or any member of the SpinCo Group relating to one or more members of the SpinCo Group and to any Post-Distribution Period (an “Acquiror Tax Proceeding”). Acquiror shall have absolute discretion with respect to any decisions to be made, or the nature of any action to be taken, with respect to any Acquiror Tax Proceeding; provided, however, that to the extent any such matter is reasonably likely to give rise to a claim for indemnity by SpinCo or Acquiror against Parent under Section 12(b) of this Agreement, (i) Acquiror shall keep Parent informed of all material developments and events relating to such Acquiror Tax Proceeding, (ii) at its own cost and expense, Parent shall have the right to participate in (but not to control) the defense of any such Acquiror Tax Proceeding and (iii) Acquiror shall not settle or compromise any such tax claim without the prior written consent of Parent (which shall not be unreasonably withheld, conditioned or delayed). If the Acquiror Group acknowledges in writing that it is liable for the Taxes at issue in any Acquiror Tax Proceeding subject to the proviso in the previous sentence, the rights of Parent in such proviso shall not apply to such Acquiror Tax Proceeding to the extent such Acquiror Tax Proceeding relates to the Taxes that are the subject of such acknowledgment.

specifically the performance of the terms and provisions of this Agreement without proof of actual Damages, this being in addition to any other remedy to which any such party is entitled at Law or in equity. Each party hereto further agrees that no other party or any other Person will be required to obtain, furnish or post any bond or similar instrument in connection with or as a condition to obtaining any remedy referred to in this Section 20, and each party hereto irrevocably waives any right it may have to require the obtaining, furnishing or posting of any such bond or similar instrument.

Except as otherwise expressly provided elsewhere in this Agreement or any other Exit Transaction Document, any provision herein which contemplates the agreement, approval or consent of, or exercise of any right of, a party, such party may give or withhold such agreement, approval or consent, or exercise such right, in its sole and absolute discretion, the parties hereby expressly disclaiming any implied duty of good faith and fair dealing or similar concept.

SECTION 22. Entire Agreement; Amendments and Waivers.

(a) Entire Agreement.

(i) This Agreement and the other Transaction Documents, including any related annexes, schedules and exhibits, as well as any other agreements and documents referred to herein and therein, together constitute the entire agreement among the parties with respect to the subject matter hereof and thereof and supersede all prior negotiations, agreements and understandings of the parties of any nature, whether oral or written, with respect to such subject matter. If there is a conflict between any provision of this Agreement and a provision of any other Transaction Document, the provision of this Agreement will control unless specifically provided otherwise in this Agreement.

34

(ii) THE PARTIES ACKNOWLEDGE AND AGREE THAT NO REPRESENTATION, WARRANTY, PROMISE, INDUCEMENT, UNDERSTANDING, COVENANT OR AGREEMENT HAS BEEN MADE OR RELIED UPON BY ANY PARTY OTHER THAN THOSE EXPRESSLY SET FORTH IN THIS AGREEMENT AND IN THE OTHER TRANSACTION DOCUMENTS, INCLUDING ANY CERTIFICATE ISSUED IN ACCORDANCE THEREWITH.

(b) Amendments and Waivers.

(i) This Agreement may be amended, and any provision of this Agreement may be waived, if and only if such amendment or waiver, as the case may be, is in writing and signed, in the case of an amendment, by the parties or, in the case of a waiver, by the party against whom the waiver is to be effective.

(ii) No failure or delay by either party in exercising any right, power or privilege under this Agreement shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right, power or privilege. Except as otherwise provided herein, no action taken pursuant to this Agreement, including any investigation by or on behalf of any party, shall be deemed to constitute a waiver by the party taking such action of compliance with any representations, warranties, covenants or agreements contained in this Agreement.
