The Parties agree to allocate all Tax Items for Federal Income Tax purposes for the Tax year that includes the Extraordinary Reduction Date with respect to each such Applicable SpinCo CFC with respect to which such an election is made to any periods ending on or prior to the Extraordinary Reduction Date based on a closing of the books method under Treasury Regulations Section 1.1502-76, to the extent permitted by Treasury Regulations Section 1.245A‑5(e)(3)(i) (or any successor guidance).

The Responsible Party shall compute the amount of Tax required to be paid to the applicable Tax Authority (taking into account the requirements of Section 3.05 relating to consistent accounting practices, as applicable) with respect to such Tax Return on such Payment Date and shall notify the other Party of the amount the Responsible Party has determined, for purposes of filing such Tax Return, is required to be paid by the other Party in respect of such Tax Return under this

(b) Computation and Payment of Liability with Respect to Tax Due. Within thirty (30) days following the latest of (i) the Due Date of any Tax Return, (ii) the date on which such Tax Return is filed and (iii) the date upon which notice is given pursuant to Section 4.01(a):

(i) If Parent is the Responsible Party, then SpinCo shall pay to Parent the amount for which SpinCo is responsible under the provisions of Article 2.

(ii) If SpinCo is the Responsible Party, then Parent shall pay to SpinCo the amount for which Parent is responsible under the provisions of Article 2.

(c) Adjustments Resulting in Underpayments. In the case of any adjustment pursuant to a Final Determination with respect to any such Tax Return, the Responsible Party shall pay to the applicable Tax Authority when due any additional Tax due with respect to such Tax Return required to be paid as a result of such adjustment pursuant to a Final Determination. The Responsible Party shall compute the amount for which the other Party is responsible in accordance with Article 2 and such other Party shall pay to the Responsible Party any amount due to the Responsible Party under Article 2 within thirty (30) days from the later of (i) the date the additional Tax was paid by the Responsible Party, or (ii) the date of receipt of a written notice and demand from the Responsible Party for payment of the amount due, accompanied by evidence of payment and a statement detailing the Taxes paid and describing in reasonable detail the particulars relating thereto.

Section 4.02 Indemnification Payments. Except as otherwise provided in Section 4.01:

(a) If a Party (the “Payor”) is required under applicable Tax Law to pay to a Tax Authority a Tax for which another Party (the “Required Party”) is liable under this Agreement, the Required Party shall reimburse the Payor within ten (10) Business Days of delivery by the Payor to the Required Party of a request for payment for the amount due, together with reasonable documentation showing the basis for the calculation of such amount and evidence of payment of such Taxes paid and describing in reasonable detail the particulars relating thereto. The reimbursement shall include interest on the Tax payment computed at the Interest Rate based on the number of days from the date of the payment to the Tax Authority to the date of reimbursement under this Section 4.02.

(b) If any Party (the “Third Party Indemnifying Party”) is required under the terms of an agreement to which it is a party to pay to a third party a Tax that another Party (the “Company Indemnifying Party”) is liable for under this Agreement, the Company Indemnifying Party shall reimburse the Third Party Indemnifying Party within ten (10) Business Days of delivery by the Third Party Indemnifying Party to the Company Indemnifying Party of a request for payment for the amount due, together with reasonable documentation showing the basis for the calculation of such amount and evidence of payment of such Taxes paid and describing in reasonable detail the particulars relating thereto.

Section 4.03 Method for Making Payments. All payments required to be made under this Agreement shall be made by Parent (or the Contributing Subsidiary, as determined by Parent) directly to SpinCo and by SpinCo directly to Parent (or the Contributing Subsidiary, as determined by Parent); provided, however, that if the Parties mutually agree with respect to any such indemnification payment, any member of the Parent Group, on the one hand, may make such indemnification payment to any member of the SpinCo Group, and vice versa.

Article 5. Refunds.

Section 5.01 General.

(a) Parent shall be entitled to any Refund attributable to Federal Income Taxes due with respect to or required to be reported on any Parent Federal Consolidated Income Tax Return, State Income Taxes due with respect to or required to be reported on any Parent State Combined Income Tax Return, Foreign Income Taxes due with respect to or required to be reported on any Joint Return, any Taxes due with respect to or required to be reported on any Parent Separate Return (other than any Federal Other Taxes, State Other Taxes and Foreign Other Taxes for which SpinCo is responsible under Article 2), and any other Taxes for which Parent is liable hereunder (but not any Refunds specifically taken into account as assets in the determination of Final Net Working Capital or Final Net Indebtedness pursuant to the Separation and Distribution Agreement). Except as provided in the foregoing sentence, Section 5.02 and Section 5.03, SpinCo shall be entitled to any Refund attributable on a “with and without” basis to Taxes for which SpinCo is liable hereunder and, for the absence of doubt, any Refunds specifically taken into account in the determination of Final Net Working Capital and Final Net Indebtedness pursuant to the Separation and Distribution Agreement. A Party receiving a Refund to which another Party is entitled hereunder shall pay such Refund to such other Party within ten (10) Business Days after such Refund is received or the benefit of such Refund is realized.

(b) To the extent that an overpayment of Taxes for which Parent is liable under this Agreement is applied, in lieu of a Refund, as a credit toward or a reduction in Taxes otherwise payable for which SpinCo is liable under this Agreement and such overpayment of Taxes, if received as a Refund, would have been payable by SpinCo to Parent pursuant to this Section 5.01, SpinCo shall pay such amount to Parent no later than the Due Date for filing the Tax Return for which such overpayment is applied. To the extent that an overpayment of Taxes for which SpinCo is liable under this Agreement is applied, in lieu of a Refund, as a credit toward or a reduction in Taxes otherwise payable for which Parent is liable under this Agreement and such overpayment of Taxes, if received as a Refund, would have been payable by Parent to SpinCo pursuant to this Section 5.01, Parent shall pay such amount to SpinCo no later than the Due Date for filing the Tax Return for which such overpayment is applied.

Section 5.02 Certain Adjustments. In the event of an adjustment pursuant to a Final Determination relating to Taxes for which SpinCo, on the one hand, or Parent, on the other hand, is responsible pursuant to Article 2 (the “Adjusted Party”) which adjustment would have

given rise to a Refund for the Adjusted Party’s account under this Article 5 but for an offset against the Taxes for which Parent or SpinCo, respectively, is responsible pursuant to Article 2 (the “Benefited Party”), then the Benefited Party shall pay to the other Party, within ten (10) Business Days of the Final Determination of such adjustment, (x) an amount equal to the amount of such offset against the Taxes of the Benefited Party plus (y) interest on such amount, computed at the Interest Rate, for the period from the filing date of the Tax Return that would have given rise to such Refund to the date on which the payment by the Benefited Party was made pursuant to this Section 5.02.

Section 5.03 Certain Step-Up Tax Benefits. Parent shall be entitled to 100% of the amount of any Refund or actual reduction of cash Taxes payable that is attributable to any step-up in Tax basis of any SpinCo Assets resulting from (A) the failure of any of the Tax-Free Transactions to qualify for Tax-Free Status (except insofar as the Taxes attributable to such failure are indemnified or borne by SpinCo hereunder) or (B) the Section 336(e) Election (except insofar as the Taxes attributable to such election are indemnified or borne by SpinCo hereunder). Parent shall be entitled to annual payments from SpinCo equal to 100% of the amount of any such Refund or reduction determined on a “with or without” basis treating any applicable Tax Benefits as the last items claimed for any taxable period after the utilization of any other available Tax Benefits. To the extent permitted by applicable Law, SpinCo shall elect to receive a Refund attributable to such step-up rather than a credit toward or reduction in future Taxes. SpinCo shall pay any such Refund (or reduction in Taxes payable), plus interest computed at the Interest Rate on such amount, for the period from the filing date of the Tax Return that gives rise, or would have given rise, to such Refund to the date on which such payment was made, to Parent within ten (10) Business Days after such Refund is received or the benefit of such Refund or reduction in Taxes payable is realized. In the case of any failure of the Tax-Free Transactions to qualify for Tax-Free Status, the SpinCo Group shall file any amended SpinCo Separate Returns required to claim any such Refund or reduction in Taxes payable to which Parent is entitled hereunder and reasonably cooperate, to the extent permitted by applicable Law, to cause any step-up in Tax basis of any SpinCo Assets to be allocated to depreciable or amortizable assets.

Section 5.04 Reductions. To the extent that the amount of any Refund under this Article 5 or Section 3.08 is later reduced by a Tax Authority or in a Tax Contest, such reduction shall be allocated to the Parties in the same manner in which such Refund was allocated pursuant to this Article 5 or Section 3.08, and an appropriate adjusting payment shall be promptly made.

contributions or acquisitions, or a series of such transactions or events), other than the Merger, the Separation and Distribution Agreement, or any other Transaction Document, that cause any of the Distributions to be treated as part of a Plan (which Plan may include the Merger) pursuant to which one or more Persons acquire directly or indirectly stock of SpinCo or any Section 355 Company representing a Fifty-Percent or Greater Interest therein, as applicable,

(iii) any action or failure to act by SpinCo (after the Effective Time), Merger Partner, Merger Partner Equityholder, any member of the SpinCo Group (in the case of the SpinCo Pre-Transaction Group, after the Effective Time) or, in each case, any of their respective Affiliates or Group members (including, without limitation, any amendment to such Person’s certificate of incorporation (or other organizational documents), whether through a stockholder vote or otherwise) affecting the voting rights of SpinCo’s Capital Stock or a Section 355 Company’s Capital Stock (including, without limitation, through the conversion of one class of SpinCo or Section 355 Company Capital Stock into another class of SpinCo or Section 355 Company Capital Stock), other than entering into the Merger, the Separation and Distribution Agreement, or any other Transaction Document, or

(b) Parent shall be responsible for any liability for Separation Tax Losses resulting from one or more of the following:

(i) the direct or indirect acquisition following the Merger of all or a portion of Parent’s stock or the Parent Group’s assets by any means whatsoever by any Person,

treated as part of a Plan (which Plan may include the Merger) pursuant to which one or more Persons acquire directly or indirectly stock of Parent representing a Fifty-Percent or Greater Interest therein, or

(iii) any action or failure to act by any member of the Parent Group that could cause the Tax-Free Transactions (other than the Merger) to fail to qualify for Tax-Free Status, except to the extent that after due inquiry and consultation with a Tax Advisor, such Person did not know (and should not reasonably have expected) that such action could cause the Tax-Free Transactions (other than the Merger) to fail to qualify for Tax-Free Status, other than entering into the Merger, disposing of the Retained Shares (whether by means of a Clean-Up Distribution, a Debt-for-Equity Exchange or otherwise) and disposing, or permitting dispositions of, the SpinCo shares set forth in Schedule B ; provided, for the avoidance of doubt, that the exclusion of the Merger above in this clause (iii) shall not exclude any act or failure to act (other than entering into the Merger) that would affect Tax-Free Status of any of the Tax-Free Transactions (other than the Merger) as a result of affecting the Tax-Free Status of the Merger.

(c) Notwithstanding anything in Section 6.04(b) or any other provision of this Agreement, the Separation and Distribution Agreement or the Merger Agreement to the contrary:

(i) SpinCo shall be responsible for any Separation Tax Losses resulting (for the avoidance of doubt, in whole or in part) from an acquisition after the Merger (other than the Known Acquisitions) of any Capital Stock or assets of SpinCo or any member of the SpinCo Group by any means whatsoever by any Person or any action or failure to act by SpinCo or any member of the SpinCo Group affecting the voting rights of SpinCo or Section 355 Company Capital Stock or the stock of any member of the SpinCo Group.

(ii) SpinCo shall not be responsible for Separation Tax Losses under Section 6.04(a) and Section 6.04(c) to the extent that the relevant Tax-Free Transactions (other than the Merger) did not qualify for Tax-Free Status at the time they were taken solely as a result of facts and circumstances pertaining to the Parent Group (or the SpinCo Pre-Transaction Group) existing as of immediately after the Merger (it being agreed and understood that this clause (ii) shall not relieve SpinCo of responsibility it would otherwise have hereunder in the case of a failure to qualify for Tax-Free Status that arises both as a result of facts and circumstances existing as of immediately after the Merger and facts and circumstances arising thereafter).

(d) Parent or SpinCo, as applicable, (the “Indemnifying Party”) shall pay to SpinCo or Parent, as applicable (the “Indemnified Party”), the amount of any Separation Tax Losses for which the Indemnifying Party is responsible under Section 2.06, Section 2.07 or this Section 6.04:

Section 7.01 Assistance and Cooperation.

(a) Parent and SpinCo shall reasonably cooperate (and cause their respective Affiliates to reasonably cooperate) with each other and with each other’s agents, including accounting firms and legal counsel, in connection with Tax matters relating to such Parties and their Affiliates, including (i) preparation and filing of Tax Returns, (ii) determining the liability for and amount of any Taxes due (including estimated Taxes) or the right to and amount of any Tax Benefit, (iii) examinations of Tax Returns, (iv) any administrative or judicial proceeding in respect of Taxes assessed or proposed to be assessed, and (v) the matters described in Schedule 7.01 to this Agreement. Such cooperation shall include making all information and documents in a Party’s possession relating to any other Party and its Affiliates available to such other Party, upon reasonable notice, as provided in Article 8. Parent and SpinCo shall also make available to any other Party, as reasonably requested and on a mutually convenient basis, personnel (including officers, directors, employees, and agents of such Parties or their respective Affiliates) responsible for preparing, maintaining, and interpreting information and documents relevant to Taxes, and personnel reasonably required as witnesses or for purposes of providing information or documents in connection with any administrative or judicial proceedings relating to Taxes. Parent, SpinCo, each member of their respective Groups, and Merger Partner Equityholder shall cooperate and take any and all actions reasonably requested by Parent, SpinCo, or Merger Partner Equityholder in connection with obtaining the Tax Opinions, the IRS Ruling and any other tax opinions or rulings to be delivered in connection with the Transactions (including, without limitation, by making any new representation or covenant, confirming any previously made representation or covenant, or providing any materials or information reasonably requested by any Tax Advisor or Tax Authority).

(b) Any information or documents provided under this Article 7 or Article 8 shall be kept confidential by the Party receiving the information or documents, except as may otherwise be necessary in connection with the filing of Tax Returns or in connection with any administrative or judicial proceedings relating to Taxes. In addition, in the event that Parent determines that the provision of any information or documents to SpinCo or any of its respective Affiliates, or SpinCo reasonably determines that the provision of any information or documents to Parent or any of its Affiliates, could be commercially detrimental, violate any Law or agreement, or waive any Privilege, the Parties shall use reasonable best efforts to permit each other’s compliance with its obligations under this Article 7 and Article 8 in a manner that avoids any such harm or consequence.

Section 7.02 Tax Return Information. Each of SpinCo and Parent, and each member of their respective Groups, acknowledges that time is of the essence in relation to any request for information, assistance, or cooperation made by Parent or SpinCo pursuant to this Agreement. Each of SpinCo and Parent, and each member of their respective Groups, acknowledge that failure to conform to the deadlines set forth in this Agreement could cause irreparable harm. Each of SpinCo and Parent shall provide to the other Party information and documents relating to its Group reasonably required by the Responsible Party to prepare Tax Returns or conduct Tax Contests. Any information or documents the requesting Party requires to prepare such Tax Returns shall be provided in such form as the requesting Party reasonably requests and at or prior to the time reasonably specified by the requesting Party so as to enable the requesting Party to file such Tax Returns on a timely basis.

Section 7.03 Reliance by Parent. If any member of the SpinCo Group supplies information to a member of the Parent Group in connection with Taxes and an officer of a member of the Parent Group signs a statement or other document under penalties of perjury in reliance upon the accuracy of such information, then upon the written request of such member of the Parent Group identifying the information being so relied upon, the chief financial officer of SpinCo (or any officer of SpinCo as designated by the chief financial officer of SpinCo) shall certify in writing that to his or her knowledge (based upon consultation with appropriate employees) the information so supplied is accurate and complete.

Section 7.04 Reliance by SpinCo. If any member of the Parent Group supplies information to a member of the SpinCo Group in connection with Taxes and an officer of a member of the SpinCo Group, as applicable, signs a statement or other document under penalties of perjury in reliance upon the accuracy of such information, then upon the written request of such member of the SpinCo Group identifying the information being so relied upon, the chief financial officer of Parent (or any officer of Parent as designated by the chief financial officer of Parent) shall certify in writing that to his or her knowledge (based upon consultation with appropriate employees) the information so supplied is accurate and complete.

Article 8. Tax Records.

Section 8.01 Retention of Tax Records. Each Company shall preserve and keep all Tax Records in its possession as of the date hereof relating to its Taxes for Pre-Distribution Periods or Taxes or Tax matters that are the subject of this Agreement, in each case, for so long as the contents thereof may become material in the administration of any matter under the Code

or other applicable Tax Law, but in any event until the later of (a) the expiration of any applicable statutes of limitations (including any waivers or extensions thereof), or (b) seven years after the Distribution Date (such later date, the “Retention Date”). After the Retention Date, each Company may dispose of such Tax Records. If, prior to the Retention Date, a Company reasonably determines that any Tax Records which it would otherwise be required to preserve and keep under this Article 8 are no longer material in the administration of any matter under the Code or other applicable Tax Law and the other Parties agree, then such first Party may dispose of such Tax Records upon sixty (60) days’ prior notice to the other Parties. Any notice of an intent to dispose given pursuant to this Section 8.01 shall include a list of the Tax Records to be disposed of describing in reasonable detail each file, book, or other record accumulation being disposed. The notified Party shall have the opportunity, at its cost and expense, to copy or remove, within such sixty (60)-day period, all or any part of such Tax Records.

Section 8.02 Access to Tax Records. The Companies and their respective Affiliates shall make available to each other for inspection and copying during normal business hours upon reasonable notice all Tax Records in their possession pertaining to (a) in the case of any Tax Return of the Parent Group, the portion of such Tax Return that relates to Taxes for which the SpinCo Group may be liable pursuant to this Agreement or (b) in the case of any Tax Return of the SpinCo Group, the portion of such Tax Return that relates to Taxes for which the Parent Group may be liable pursuant to this Agreement, and shall permit the other Parties and their Affiliates, authorized agents and representatives, and any representative of a Tax Authority or other Tax auditor direct access, at the cost and expense of the requesting Party, during normal business hours upon reasonable notice, to such Tax Records, in each case to the extent reasonably required by the other Party in connection with the preparation of Tax Returns, audits, litigation, or the resolution of items under this Agreement. Notwithstanding anything to the contrary in this Agreement or any Transaction Document, in no event shall Parent be required to provide any Person with any Parent Federal Consolidated Income Tax Return, Parent State Combined Income Tax Return or any Joint Return or, in each case, any copy or portion thereof; provided, however, that to the extent any such Tax Return would be required to be delivered to SpinCo or a member of the SpinCo Group but for this sentence, Parent shall instead deliver a portion or excerpt thereof (or a pro forma Tax Return) showing solely items to the extent relating to SpinCo or the applicable members of the SpinCo Group.

Section 8.03 Preservation of Privilege. The Parties and their respective Affiliates shall not provide access to, copies of, or otherwise disclose to any Person any documentation relating to Taxes existing prior to the Distribution Date to which Privilege may reasonably be asserted without the prior written consent of the other Party, such consent not to be unreasonably withheld, conditioned, or delayed.

Article 9. Tax Contests.

Section 9.01 Notice. Each of Parent and SpinCo shall provide prompt notice to the other Parties of any written communication from a Tax Authority regarding any pending Tax audit, assessment, or proceeding or other Tax Contest of which it becomes aware related to Taxes for any Tax Period for which it reasonably expects to be indemnified by another Party hereunder or for which it reasonably may be required to indemnify another Party hereunder, or otherwise relating to the Tax-Free Status (including the resolution of any Tax Contest relating

thereto). Such notice shall attach copies of the pertinent portion of any written communication from a Tax Authority and contain factual information (to the extent known) describing any asserted Tax liability in reasonable detail and shall be accompanied by copies of any notice and other documents received from any Tax Authority in respect of any such matters. The failure of one Party to notify another of such communication in accordance with the immediately preceding sentences shall not relieve the other Party of any liability or obligation to pay such Tax or make indemnification payments under this Agreement, except to the extent that the failure to timely provide such notification materially prejudices the ability of such other Party to contest such Tax liability.

Section 9.02 Control of Tax Contests.

(a) Separate Company Taxes. In the case of any Tax Contest with respect to any Separate Return (other than a Parent Federal Consolidated Income Tax Return, Parent State Combined Income Tax Return or Parent Separate Return of Australian Income Tax), the Party that has liability for the Tax that is the subject of the Tax Contest pursuant to this Agreement (or, if both Parent and SpinCo have liability for the Tax that is the subject of the Tax Contest pursuant to this Agreement, then whichever of Parent and SpinCo has the greater reasonably expected exposure to such Tax) shall have exclusive control over the Tax Contest, including exclusive authority with respect to any settlement of such Tax liability, subject to Sections 9.02(c) and (d).

(b) Parent Federal Consolidated Income Tax Returns, Parent State Combined Income Tax Returns and Joint Returns.

(i) Subject to Section 9.02(e), in the case of any Tax Contest with respect to any Parent Federal Consolidated Income Tax Return or Parent State Combined Income Tax Return, Parent shall have exclusive control over the Tax Contest, including exclusive authority with respect to any settlement of such Tax liability.

(ii) Subject to Sections 9.02(c) and (d), in the case of any Tax Contest with respect to any Joint Return of Other Taxes, Parent shall have exclusive control over the Tax Contest, including exclusive authority with respect to any settlement of such Tax liability.

(iii) In the case of any Tax Contest with respect to any Joint Return in Australia (or any Parent Separate Return of Australian Income Tax), Parent shall have exclusive control over the Tax Contest, including exclusive authority with respect to any settlement of such Tax liability.

(c) Settlement Rights. The Party entitled to control the Tax Contest under Section 9.02(a) and Section 9.02(b)(ii) (the “Controlling Party”) shall have the sole right to contest, litigate, compromise, and settle any Tax Contest without obtaining the prior consent of (x) Parent if SpinCo is the Controlling Party and (y) SpinCo if Parent is the Controlling Party (the “Non-Controlling Party”); provided, however, (x) that to the extent any such Tax Contest under Section 9.02(a) or Section 9.02(b)(ii) may give rise to a claim for indemnity by the Controlling Party or its Affiliates against the Non-Controlling Party or its Affiliates under this

Agreement or if the Controlling Party is in a different Group from the taxpayer in the Tax Contest, the Controlling Party shall not settle any such Tax Contest without obtaining the prior written consent of the Non-Controlling Party (which consent shall not be unreasonably withheld) and (y) that Parent, in the case of a Tax Return covered by Section 2.04(b)(i) (solely with respect to the United Kingdom and then only for the Pre-Distribution Period), shall notify SpinCo of the settlement of any Tax Contest with respect to such Tax Return that would reasonably be expected to affect items reported on any Tax Return of a member of the SpinCo Group. To the extent any such Tax Contest under Section 9.02(a) may give rise to a claim for indemnity by the Controlling Party or its Affiliates against the Non-Controlling Party or its Affiliates under this Agreement or if the Controlling Party is in a different Group from the taxpayer in the Tax Contest, (i) the Controlling Party shall keep the Non-Controlling Party informed in a timely manner of all actions taken or proposed to be taken by the Controlling Party with respect to such Tax Contest; (ii) the Controlling Party shall timely provide the Non-Controlling Party copies of any written materials relating to such potential adjustment in such Tax Contest received from any Tax Authority; (iii) the Controlling Party shall timely provide the Non-Controlling Party with copies of any correspondence or filings submitted to any Tax Authority or judicial authority in connection with such Tax Contest; (iv) the Controlling Party shall consult with the Non-Controlling Party and offer the Non-Controlling Party a reasonable opportunity to comment before submitting any written materials prepared or furnished in connection with such Tax Contest; and (v) the Controlling Party shall defend such Tax Contest diligently and in good faith. The failure of the Controlling Party to take any action specified in the preceding sentences in this Section 9.02(c) with respect to the Non-Controlling Party shall not relieve the Non‑Controlling Party of any liability or obligation which it may have to the Controlling Party under this Agreement with respect to such Tax Contest except to the extent that the Non-Controlling Party was actually harmed by such failure, and in no event shall such failure relieve the Non-Controlling Party from any other liability or obligation which it may have to the Controlling Party.

(d) Tax Contest Participation. In the case of a Tax Contest under Section 9.02(a) or Section 9.02(b)(ii), unless waived by the Parties in writing, the Controlling Party shall provide the Non-Controlling Party with written notice reasonably in advance of, and the Non-Controlling Party shall have the right to attend, any formally scheduled meetings with Tax Authorities or hearings or proceedings before any judicial authorities in connection with any potential adjustment in a Tax Contest pursuant to which the Non-Controlling Party may reasonably be expected to become liable to make any indemnification payment to the Controlling Party under this Agreement. The failure of the Controlling Party to provide any notice specified in this Section 9.02(d) to the Non-Controlling Party shall not relieve the Non-Controlling Party of any liability or obligation which it may have to the Controlling Party under this Agreement with respect to such Tax Contest except to the extent that the Non-Controlling Party was actually harmed by such failure, and in no event shall such failure relieve the Non-Controlling Party from any other liability or obligation which it may have to the Controlling Party.

(e) Separation-Related Tax Contests. Notwithstanding anything in this Agreement to the contrary, Sections 9.02(c) and (d) shall not apply to any Separation-Related Tax Contest and instead (i) Parent shall have exclusive control over any Separation-Related Tax Contest, including, exclusive authority and discretion with respect to any settlement of, and positions taken in, such Tax Contest, subject to the provisions of this Section 9.02(e), and (ii) in

the event of any Separation-Related Tax Contest as a result of which SpinCo could reasonably be expected to become liable for any Tax or Separation Tax Loss, (A) Parent shall keep SpinCo informed in a timely manner of all actions taken by Parent with respect to such potential liability in such Tax Contest; (B) Parent shall provide SpinCo copies of any written materials relating to such potential liability in such Tax Contest received from any Tax Authority; (C) Parent shall timely provide SpinCo with copies of any correspondence or filings submitted to any Tax Authority or judicial authority in connection with such potential liability in such Tax Contest; (D) SpinCo shall be entitled to have one member of Cravath, Swaine & Xxxxx LLP participate in the defense of such Separation-Related Tax Contest (at its own expense) by attending any formally scheduled meetings with the relevant Tax Authority and Parent shall offer SpinCo a reasonable opportunity to comment before submitting any written materials prepared or furnished in connection with such potential liability in such Tax Contest; and (E) Parent shall not settle any such Separation-Related Tax Contest without the prior written consent of SpinCo (not to be unreasonably withheld, delayed or conditioned); provided, however, that the failure of Parent to take any action specified in any of clauses (A) through (E) above shall not relieve SpinCo of any liability or obligation which it may have to Parent under this Agreement in respect of such liability or otherwise under this Agreement.

(f) Power of Attorney. Without limiting the generality of Section 18.08, each member of the SpinCo Group shall execute and deliver to Parent (or such member of the Parent Group as Parent shall designate) any power of attorney or other similar document reasonably requested by Parent (or such designee) in connection with any Tax Contest as to which Parent is the Controlling Party and any Tax Contest in Australia (and any other Tax Contest that Parent is entitled to control hereunder), described in this Article 9, within five (5) Business Days of such request. Each member of the SpinCo Group shall take all appropriate action to facilitate Parent’s right to control, as set forth in Section 9.02(b)(iii), any Tax Contest in Australia, including forwarding any correspondence or communication received from the Tax Authority upon receipt, providing reasonable access to the online portals of the Australian Taxation Office, facilitating the ability of Parent or its designee to interact and communicate directly with the Tax Authority, refraining from making public statements about any such Tax Contest and refraining from taking any action that would interfere with such right of Parent to control such Tax Contest.

Article 10. Effective Date; Termination of Prior Intercompany Tax Allocation Agreements. Except as expressly set forth in this Agreement, as between Parent and SpinCo, this Agreement shall become effective upon the consummation of the Distribution, and as between Parent, SpinCo, Merger Partner and Merger Partner Equityholder, this Agreement shall become effective upon the consummation of the Merger. As of the date hereof or on such other date (on or prior to the Distribution Date) as Parent may determine, (a) all prior intercompany Tax allocation agreements or arrangements solely between or among any member(s) of the Parent Group, on the one hand, and any member(s) of the SpinCo Group, on the other hand, shall be terminated and (b) amounts due under or contemplated by such agreements or arrangements as of the date hereof shall be settled. Upon such termination and settlement, no further payments by or to Parent or by or to SpinCo (or any member of their respective Groups) with respect to such agreements or arrangements shall be made, and all other rights and obligations resulting from such agreements or arrangements between the Companies and their Affiliates shall cease at such time. Any payments pursuant to such agreements or arrangements shall be disregarded for purposes of computing amounts due under this Agreement.

Article 11. Survival of Obligations. The representations, warranties, covenants, and agreements set forth in this Agreement shall be unconditional and absolute and shall remain in effect without limitation as to time. The rights and obligations of the Parties and Merger Partner Equityholder under Article 2 and Article 6 shall survive (a) the sale or other transfer by either Company, Merger Partner Equityholder or any member of its respective Group of any assets or businesses or the assignment by it of any Liabilities; or (b) any merger, consolidation, business combination, sale of all or substantially all of its Assets, restructuring, recapitalization, reorganization, or similar transaction involving either Company or any of the members of its respective Group.

Article 12. Covenant Not to Sue. Each Party and Merger Partner Equityholder hereby covenants and agrees it, the members of its Group, and any Person claiming through it shall (a) not bring suit or otherwise assert any claim against any indemnified party hereunder, (b) not assert a defense against any claim asserted by any indemnified party hereunder, including before any court, arbitrator, mediator, or administrative agency anywhere in the world, and (c) waive and release (on behalf of itself, the members of its Group, and any other Person claiming through it) any claim or defense against any person, in each case, alleging that: (i) the indemnification obligations of SpinCo on the terms and conditions set forth in this Agreement are unlawful, a breach of fiduciary or other duty, void, unenforceable, unconscionable, inequitable, or otherwise improper for any reason; (ii) the indemnification obligations of Parent on the terms and conditions set forth in this Agreement are unlawful, a breach of fiduciary or other duty, void, unenforceable, unconscionable, inequitable, or otherwise improper for any reason; or (iii) the provisions of Article 2 or Article 6 are unlawful, a breach of fiduciary or other duty, void, unenforceable, unconscionable, inequitable, or otherwise improper for any reason.

Article 13. Treatment of Payments.

Section 13.01 Treatment of Tax Indemnity Payments. In the absence of any change in Tax treatment under the Code or except as otherwise required by other applicable Tax Law, any payment required by this Agreement, the Merger Agreement, or any Transaction Document (other than any payment of interest accruing after the Distribution Date) shall be reported for Tax purposes by the payor and the recipient as either (a) a contribution by the Contributing Subsidiary to SpinCo or a distribution by SpinCo to the Contributing Subsidiary (or the relevant member of its Group, respectively), as the case may be, occurring immediately prior to the applicable Distribution (but only to the extent the payment does not relate to a Tax allocated to the payor in accordance with Section 1552 of the Code or the Treasury Regulations thereunder or Treasury Regulations Section 1.1502-33(d) (or under corresponding principles of other applicable Tax Laws)) or (b) as payments of an assumed or retained liability, as determined by Parent in good faith.

Section 13.02 Interest Under This Agreement. Notwithstanding anything herein to the contrary, to the extent one Party (“Indemnitor”) makes a payment of interest to another Party (“Indemnitee”) under this Agreement with respect to the period from the date that the Indemnitee made a payment of Tax to a Tax Authority to the date that the Indemnitor reimbursed the Indemnitee for such Tax payment, the interest payment shall be treated as interest expense to the Indemnitor (deductible to the extent provided by Law) and as interest income by the Indemnitee (includible in income to the extent provided by Law). For the absence of doubt, the

amount of the payment shall not be adjusted to take into account any associated Tax Benefit to the Indemnitor or increase in Tax to the Indemnitee.

Article 14. Disagreements.

Section 14.01 Discussion. The Parties mutually desire that friendly collaboration will continue between them. Accordingly, they will endeavor, and they will cause their respective Group members to endeavor, to resolve in an amicable manner all disagreements and misunderstandings connected with their respective rights and obligations under this Agreement, including any amendments hereto. In furtherance thereof, in the event of any dispute or disagreement between any member of the Parent Group, on the one hand, and any member of the SpinCo Group, on the other hand, as to the interpretation of any provision of this Agreement or the performance of obligations hereunder (a “Dispute”), the Tax departments of the Parties shall negotiate in good faith to resolve the Dispute.

Section 14.02 Escalation. If such good faith negotiations do not resolve the Dispute, the Parties shall either appoint a nationally recognized independent public accounting firm (the “Accounting Firm”) to resolve such Dispute or, if any Party does not consent to the appointment of the Accounting Firm, such Party, subject to Section 10.2 (as if references therein to the “Agreement” were references to this Agreement) and Section 10.9 of the Merger Agreement, may submit the Dispute (or such series of related Disputes) to any court of competent jurisdiction as set forth in Section 10.2 of the Merger Agreement. The Accounting Firm, if appointed, shall make determinations with respect to the disputed items based solely on representations made by Parent, SpinCo, and members of their respective Groups, and not by independent review, and shall function only as an expert and not as an arbitrator and shall be required to make a determination in favor of one Party only. The Parties shall require the Accounting Firm to resolve all Disputes submitted to it no later than sixty (60) days after such submission, but in no event later than any due date for the payment of Taxes or the filing of the applicable Tax Return, if applicable, and agree that all decisions by the Accounting Firm with respect thereto shall be final and conclusive and binding on the Parties. The Accounting Firm shall resolve all Disputes submitted to it in a manner consistent with this Agreement and, to the extent not inconsistent with this Agreement, in a manner consistent with the Past Practices of the Parent Group, except as otherwise required by applicable Law. The Parties shall require the Accounting Firm to render all determinations in writing and to set forth, in reasonable detail, the basis for such determination. The fees and expenses of the Accounting Firm shall be borne equally by the Parent Group, on the one hand, and the SpinCo Group, on the other hand.

Article 15. Late Payments. Any amount not paid within ten (10) Business Days of the date when due pursuant to this Agreement shall accrue interest at the rate per annum published in the Wall Street Journal from time to time as the prime lending rate prevailing during any relevant period plus two percent (2%) (or, with respect to any payment obligation which a Party is disputing in good faith in accordance with the dispute resolution process set forth in Article 14, such interest shall accrue commencing on the date such dispute is finally resolved (including, if applicable, by an order of court of competent jurisdiction)), or, if less, the maximum interest rate allowable under applicable Law in the applicable jurisdiction, compounded quarterly. Notwithstanding the foregoing, at no time shall any Party be obligated pursuant to the foregoing sentence to pay interest at a rate exceeding the maximum interest rate

allowable under applicable Law in any applicable jurisdiction. If, by the terms of such foregoing sentence, any Party would otherwise be obligated at any time to pay interest at a rate in excess of such maximum interest rate in such applicable jurisdiction, then the interest payable shall be recomputed and reduced to such maximum interest rate, and the portion of all prior interest payments exceeding such maximum rate shall be applied to payment of the underlying principal amount.

Article 16. Expenses. Except as otherwise provided in this Agreement, each Party and its Affiliates shall bear their own expenses incurred in connection with preparation of Tax Returns, Tax Contests, and other matters related to Taxes under the provisions of this Agreement.

Article 17. Relationship to Employee Matters Agreement. If and to the extent there is a conflict or inconsistency between any provision of this Agreement and a provision in the Employee Matters Agreement (as defined in the Merger Agreement), then the provision of the Employee Matters Agreement shall control in relation to a matter principally addressed by the Employee Matters Agreement.

Article 18. General Provisions.

Section 18.01 Corporate Power; Facsimile Signatures. Parent, SpinCo, Merger Partner, and Xxxxxx Partner Equityholder each represent on their own behalf, as follows:

None of Parent, SpinCo, Merger Partner, or Merger Partner Equityholder may assign its rights or delegate its duties under this Agreement without the prior written consent of the other Parties and Merger Partner Equityholder, as applicable. Any attempted assignment or delegation in breach of this Section 18.04 shall be null and void. This Agreement shall be binding upon and inure to the benefit of Parent, SpinCo, Merger Partner, and Xxxxxx Partner Equityholder and their respective permitted successors and assigns.

shall be construed to confer upon or give any Person, other than Parent, SpinCo, Xxxxxx Partner, and Merger Partner Equityholder, any rights or remedies under or by reason of this Agreement.

Section 18.05 Force Majeure. No Party nor Merger Partner Equityholder (nor any Person acting on behalf of any of them) shall have any liability or responsibility for failure to fulfill any obligation (other than a payment obligation) under this Agreement so long as and to the extent to which the fulfillment of such obligation is prevented, frustrated, hindered or delayed as a consequence of circumstances of Force Majeure. A Party or Merger Partner Equityholder claiming the benefit of this provision shall, as soon as reasonably practicable after the occurrence of any such event, (a) notify the other Parties and Merger Partner Equityholder, as applicable, of the nature and extent of any such Force Majeure and (b) use due diligence to remove any such causes and resume performance under this Agreement as soon as feasible.

After the Distribution Time, this Agreement may not be terminated except by an agreement in writing signed by each of the Parties. In the event of such termination, this Agreement shall become void and no Party nor Merger Partner Equityholder, or any of its respective officers and directors, shall have any liability to any Person by reason of this Agreement. This Agreement may be amended or modified, in whole or in part, only by a duly authorized agreement in writing executed by SpinCo and Parent (and, if prior to the Distribution by Parent, Merger Partner) which makes reference to this Agreement; provided that any amendment that would have an adverse impact on the rights or obligations of Merger Partner Equityholder hereunder shall require the agreement in writing of Merger Partner Equityholder.

Section 18.07 Performance. Parent will cause to be performed, and hereby guarantees the performance of, all actions, agreements and obligations set forth in this Agreement to be performed by any member of the Parent Group. SpinCo will cause to be performed, and hereby guarantees the performance of, all actions, agreements and obligations set forth in this Agreement to be performed by any member of the SpinCo Group.

Unless expressly required in this Agreement, no Party nor Merger Partner Equityholder shall be required to exhaust all remedies available under other agreements or at law or equity before recovering under the remedies provided in this Agreement.
