(e) Zoetis Internal Restructuring. Zoetis shall not engage in, cause or permit any internal restructuring (including by making or revoking any election under Treasury Regulation Section 301.7701-3) involving a member of the Zoetis Group or any contribution, sale or other transfer of any of the assets directly or indirectly contributed to Zoetis as described in the Separation Agreement, to Zoetis or any of its Affiliates, apart from sales in the ordinary course of business (any such action, an “Internal Restructuring”) during or with respect to any Tax Period (or portion thereof) ending on or prior to the final Distribution Date without obtaining the prior written consent of Pfizer. Zoetis shall provide written notice to Pfizer describing any Internal Restructuring proposed to be taken during or with respect to any Tax Period (or portion thereof) beginning after the final Distribution Date and ending on or prior to the two-year anniversary of such Distribution Date, and shall consult with Pfizer regarding any such proposed actions reasonably in advance of taking any such proposed actions and shall consider in good faith any comments from Pfizer relating thereto.

Section 6.02 Restrictions on Pfizer. Pfizer agrees that it will not take or fail to take, or permit any Pfizer Affiliate, as the case may be, to take or fail to take, any action (i) where such action or failure to act would be inconsistent with or cause to be untrue any statement, information, covenant or representation in any Representation Letters or Tax Opinions/Rulings, or (ii) which adversely affects or could reasonably be expected to adversely affect (A) the Tax-Free Status of the Contribution, the Debt-for-Debt Exchange, the Debt-for-Equity Exchange and the Distribution, or (B) the qualification of any Separation Transaction under U.S. federal, state, local or non-U.S. Tax Law as tax free (including, but not limited to, those transactions described in any of the Tax Opinions/Rulings received with respect to such Separation Transaction) from so qualifying; provided, however, that this Section 6.02 shall not be construed as obligating Pfizer to consummate the Distribution nor shall it be construed as preventing Pfizer from terminating the Separation Agreement pursuant to Section 10.1 thereof.

(d) Zoetis shall pay Pfizer the amount of any Tax-Related Losses for which Zoetis is responsible under this Section 6.04: (A) in the case of Tax-Related Losses described in clause (i) of the definition of Tax-Related Losses no later than two Business Days prior to the date Pfizer files, or causes to be filed, the applicable Tax Return for the year of the Contribution or Distribution, as applicable (the “Filing Date”) (provided that if such Tax-Related Losses arise pursuant to a Final Determination described in clause (a), (b) or (c) of the definition of “Final Determination”, then Zoetis shall pay Pfizer no later than two Business Days after the date of such Final Determination with interest calculated at the Prime Rate plus two percent, compounded semiannually, from the date that is two Business Days prior to the Filing Date through the date of such Final Determination) and (B) in the case of Tax-Related Losses described in clause (ii) or (iii) of the definition of Tax-Related Losses, no later than two Business Days after the date Pfizer pays such Tax-Related Losses. Pfizer shall pay Zoetis the amount of any Tax-Related Losses (described in clause (ii) or (iii) of the definition of Tax-Related Loss) for which Pfizer is responsible under this Section 6.04 no later than two Business Days after the date Zoetis pays such Tax-Related Losses.

Section 7. Assistance and Cooperation.

Section 7.01 Assistance and Cooperation.

(a) The Companies shall cooperate (and cause their respective Affiliates to cooperate) with each other and with each other’s agents, including accounting firms and legal counsel, in connection with Tax matters relating to the Companies and their Affiliates including (i) preparation and filing of Tax Returns, (ii) determining the liability for and amount of any Specified Taxes due (including estimated Taxes) or the right to and amount of any refund of Taxes, (iii) examinations of Tax Returns, and (iv) any administrative or judicial proceeding in respect of Specified Taxes assessed or proposed to be assessed. Such cooperation shall include making all information and documents in their possession relating to the other Company and its Affiliates available to such other Company as provided in Section 8. Each of the Companies

shall also make available to the other, as reasonably requested and available, personnel (including officers, directors, employees and agents of the Companies or their respective Affiliates) responsible for preparing, maintaining, and interpreting information and documents relevant to Specified 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 Specified Taxes. In the event that a member of the Pfizer Group, on the one hand, or a member of the Zoetis Group, on the other hand, suffers a Tax detriment as a result of a Transfer Pricing Adjustment, the Companies shall cooperate pursuant to this Section 7 to seek any competent authority relief that may be available with respect to such Transfer Pricing Adjustment. Zoetis shall cooperate with Pfizer and take any and all actions reasonably requested by Pfizer in connection with obtaining the Tax Opinions/Rulings (including, without limitation, by making any new representation or covenant, confirming any previously made representation or covenant or providing any materials or information requested by any Tax Advisor or Tax Authority; provided that, Zoetis shall not be required to make or confirm any representation or covenant that is inconsistent with historical facts or as to future matters or events over which it has no control).

(b) Any information or documents provided under this Section 7 shall be kept confidential by the Company 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. Notwithstanding any other provision of this Agreement or any other agreement, (i) neither Pfizer nor any Pfizer Affiliate shall be required to provide Zoetis or any Zoetis Affiliate or any other Person access to or copies of any information or procedures (including the proceedings of any Tax Contest) other than information or procedures that relate to Zoetis, the business or assets of Zoetis or any Zoetis Affiliate and (ii) in no event shall Pfizer or any Pfizer Affiliate be required to provide Zoetis, any Zoetis Affiliate 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. In addition, in the event that Pfizer determines that the provision of any information to Zoetis or any Zoetis Affiliate could be commercially detrimental, violate any law or agreement or waive any Privilege, the parties shall use reasonable best efforts to permit compliance with its obligations under this Section 7 in a manner that avoids any such harm or consequence.

Section 7.02 Income Tax Return Information. Zoetis and Pfizer acknowledge that time is of the essence in relation to any request for information, assistance or cooperation made by Pfizer or Zoetis pursuant to Section 7.01 or this Section 7.02. Zoetis and Pfizer acknowledge that failure to conform to the reasonable deadlines set by Pfizer or Zoetis could cause irreparable harm. Each Company shall provide to the other Company information and documents relating to its Group required by the other Company to prepare Tax Returns, including, but not limited to, any pro forma returns required by the Responsible Company for purposes of preparing such Tax Returns. Any information or documents the Responsible Company requires to prepare such Tax Returns shall be provided in such form as the Responsible Company reasonably requests and at or prior to the time reasonably specified by the Responsible Company so as to enable the Responsible Company to file such Tax Returns on a timely basis.

Section 7.03 Reliance by Pfizer. If any member of the Zoetis Group supplies information to a member of the Pfizer Group in connection with a Tax liability and an officer of a member of the Pfizer 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 Pfizer Group identifying the information being so relied upon, the chief financial officer of Zoetis (or any officer of Zoetis as designated by the chief financial officer of Zoetis) 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 Zoetis. If any member of the Pfizer Group supplies information to a member of the Zoetis Group in connection with a Tax liability and an officer of a member of the Zoetis 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 Zoetis Group identifying the information being so relied upon, the chief financial officer of Pfizer (or any officer of Pfizer as designated by the chief financial officer of Pfizer) 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 8. Tax Records.

Section 8.01 Retention of Tax Records. Each Company shall preserve and keep all Tax Records exclusively relating to the assets and activities of its Group for Pre-Deconsolidation Periods, and Pfizer shall preserve and keep all other Tax Records relating to Taxes of the Groups for Pre-Deconsolidation Tax Periods, 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 (i) the expiration of any applicable statutes of limitations, or (ii) seven years after the Deconsolidation Date (such later date, the “Retention Date”). After the Retention Date, each Company may dispose of such Tax Records upon 60 Business Days’ prior written notice to the other Company. If, prior to the Retention Date, (a) a Company reasonably determines that any Tax Records which it would otherwise be required to preserve and keep under this Section 8 are no longer material in the administration of any matter under the Code or other applicable Tax Law and the other Company agrees, then such first Company may dispose of such Tax Records upon 60 Business Days’ prior notice to the other Company. 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 Company shall have the opportunity, at its cost and expense, to copy or remove, within such 60 Business Day period, all or any part of such Tax Records. If, at any time prior to the Retention Date,

Zoetis determines to decomission or otherwise discontinue any computer program or information technology system used to access or store any Tax Records, then Zoetis may decomission or discontinue such program or system upon 90 days’ prior notice to Pfizer and Pfizer shall have the opportunity, at its cost and expense, to copy, within such 60 Business Day period, all or any part of the underlying data relating to the Tax Records accessed by or stored on such program or system.

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 (and, for the avoidance of doubt, any pertinent underlying data accessed or stored on any computer program or information technology system) in their possession and shall permit the other Company and its Affiliates, authorized agents and representatives and any representative of a Taxing Authority or other Tax auditor direct access, at the cost and expense of such other Company, during normal business hours upon reasonable notice to any computer program or information technology system used to access or store any Tax Records, in each case to the extent reasonably required by the other Company in connection with the preparation of Tax Returns or financial accounting statements, audits, litigation, or the resolution of items under this Agreement.

Section 8.03 Preservation of Privilege. No member of the Zoetis Group shall provide access to, copies of, or otherwise disclose to any Person any documentation relating to Specified Taxes existing as of the date hereof to which Privilege may reasonably be asserted without the prior written consent of Pfizer, such consent not to be unreasonably withheld.

Section 9. Tax Contests.

Section 9.01 Notice. Each of the Companies shall provide prompt notice to the other Company 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 Tax Periods for which it is indemnified by the other Company hereunder or for which it may be required to indemnify the other Company hereunder. 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. If an indemnified party has knowledge of an asserted Tax liability with respect to a matter for which it is to be indemnified hereunder and such party fails to give the indemnifying party prompt notice of such asserted Tax liability and the indemnifying party is entitled under this Agreement to contest the asserted Tax liability, then (i) if the indemnifying party is precluded from contesting the asserted Tax liability in any forum as a result of the failure to give prompt notice, the indemnifying party shall have no obligation to indemnify the indemnified party for any Taxes arising out of such asserted Tax liability, and (ii) if the indemnifying party is not precluded from contesting the asserted Tax liability in any forum, but such failure to give prompt notice results in a material monetary detriment to the indemnifying party, then any amount which the indemnifying party is otherwise required to pay the indemnified party pursuant to this Agreement shall be reduced by the amount of such detriment.

Section 9.02 Control of Tax Contests.

(a) Separate Returns. In the case of any Tax Contest with respect to any Separate Return, the Company having liability for the Tax pursuant to Section 2 hereof 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) below.

(b) Joint Return. In the case of any Tax Contest with respect to any Joint Return, Pfizer 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) below.

(c) Settlement Rights. The Controlling Party shall have the sole right to contest, litigate, compromise and settle any Tax Contest without obtaining the prior consent of the Non-Controlling Party. Unless waived by the parties in writing, in connection with any potential adjustment in a Tax Contest as a result of which adjustment the Non-Controlling Party may reasonably be expected to become liable to make any indemnification payment to the Controlling Party under this Agreement: (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 potential adjustment in 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 potential adjustment in 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 potential adjustment in 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 sentence with respect to the Non-Controlling Party shall not relieve the Non-Controlling Party of any liability and/or obligation which it may have to the Controlling Party under this Agreement 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. In the case of any Tax Contest described in Section 9.02(a) or (b), “Controlling Party” means the Company entitled to control the Tax Contest under such Section and “Non-Controlling Party” means the other Company.

(d) Tax Contest Participation. 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 and/or obligation which it may have to the Controlling Party under this Agreement 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) Power of Attorney. Each member of the Zoetis Group shall execute and deliver to Pfizer (or such member of the Pfizer Group as Pfizer shall designate) any power of attorney or other similar document reasonably requested by Pfizer (or such designee) in connection with any Tax Contest (as to which Pfizer is the Controlling Party) described in this Section 9. Each member of the Pfizer Group shall execute and deliver to Zoetis (or such member of the Zoetis Group as Zoetis shall designate) any power of attorney or other similar document requested by Zoetis (or such designee) in connection with any Tax Contest (as to which Zoetis is the Controlling Party) described in this Section 9.

Section 10. Effective Date. This Agreement shall be effective as of the date hereof.

Section 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.

Section 12. Treatment of Payments.

Section 12.01 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 Tax indemnity payments made by a Company under this Agreement shall be reported for Tax purposes by the payor and the recipient as distributions or capital contributions, as appropriate, occurring immediately before the Deconsolidation (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 regulations thereunder or Treasury Regulation Section 1.1502-33(d) (or under corresponding principles of other applicable Tax Laws)) or as payments of an assumed or retained liability. Except to the extent provided in Section 12.02, any Tax indemnity payment made by a Company under this Agreement shall be increased as necessary so that after making all payments in respect to Taxes imposed on or attributable to such indemnity payment, the recipient Company receives an amount equal to the sum it would have received had no such Taxes been imposed.

Section 12.02 Interest Under This Agreement. Anything herein to the contrary notwithstanding, to the extent one Company (“Indemnitor”) makes a payment of interest to another Company (“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). 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.

Section 13. Disagreements.

Section 13.01 Discussion. The Companies mutually desire that friendly collaboration will continue between them. Accordingly, they will try, and they will cause their respective Group members to try, 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 (a “Dispute”) between any member of the Pfizer Group and any member of the Zoetis Group as to the interpretation of any provision of this Agreement or the performance of obligations hereunder, the Tax departments of the Companies shall negotiate in good faith to resolve the Dispute.

Section 13.02 Escalation. If such good faith negotiations do not resolve the Dispute, then the matter, upon written request of either Company, will be referred for resolution to representatives of the parties at a senior level of management of the parties pursuant to the procedures set forth in Section 8.02(a) of the Separation Agreement.

Section 13.03 Referral to Tax Advisor. If the parties are not able to resolve the Dispute through the escalation process referred to above, then the matter will be referred to a Tax Advisor acceptable to each of the Companies to act as an arbitrator in order to resolve the Dispute. In the event that the Companies are unable to agree upon a Tax Advisor within 15 Business Days following the completion of the escalation process, the Companies shall each separately retain an independent, nationally recognized law or accounting firm (each, a “Preliminary Tax Advisor”), which Preliminary Tax Advisors shall jointly select a Tax Advisor on behalf of the Companies to act as an arbitrator in order to resolve the Dispute. The Tax Advisor may, in its discretion, obtain the services of any third-party appraiser, accounting firm or consultant that the Tax Advisor deems necessary to assist it in resolving such disagreement. The Tax Advisor shall furnish written notice to the Companies of its resolution of any such Dispute as soon as practical, but in any event no later than 30 Business Days after its acceptance of the matter for resolution. Any such resolution by the Tax Advisor will be conclusive and binding on the Companies. Following receipt of the Tax Advisor’s written notice to the Companies of its resolution of the Dispute, the Companies shall each take or cause to be taken any action necessary to implement such resolution of the Tax Advisor. Each Company shall pay its own fees and expenses (including the fees and expenses of its representatives) incurred in connection with the referral of the matter to the Tax Advisor (and the Preliminary Tax Advisors, if any). All fees and expenses of the Tax Advisor (and the Preliminary Tax Advisors, if any) in connection with such referral shall be shared equally by the Companies.

Section 13.04 Injunctive Relief. Nothing in this Section 13 will prevent either Company from seeking injunctive relief if any delay resulting from the efforts to resolve the Dispute through the process set forth above could result in serious and irreparable injury to either Company. Notwithstanding anything to the contrary in this Agreement, Pfizer and Zoetis are the only members of their respective Group entitled to commence a dispute resolution procedure under this Agreement, and each of Pfizer and Zoetis will cause its respective Group members not to commence any dispute resolution procedure other than through such party as provided in this Section 13.

Section 14. Late Payments. Any amount owed by one party to another party under this Agreement which is not paid when due shall bear interest at the Prime Rate plus two percent, compounded semiannually, from the due date of the payment to the date paid. To the extent interest required to be paid under this Section 14 duplicates interest required to be paid under any other provision of this Agreement, interest shall be computed at the higher of the interest rate provided under this Section 14 or the interest rate provided under such other provision.

Section 15. 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.

All such other agreements, including, but not limited to, that certain Tax Sharing Agreement by and among Pfizer and certain of its subsidiaries, dated December 31, 2003, shall be of no further effect between the Companies and any rights or obligations existing thereunder shall be fully and finally settled, calculated as of the date hereof.
