2.1 Registration.

(a) Request. Any Holder(s) of Registrable Securities (collectively, the “Initiating Holder”) shall have the right to request that Zoetis file a Registration Statement with the SEC on the appropriate registration form for all or part of the Registrable Securities held by such Holder once such Registrable Securities are no longer subject to the underwriter lock-up applicable to the IPO (which may be due to the expiration or waiver of such lock-up with respect to such Registrable Securities) by delivering a written request to Zoetis specifying the number of shares of Registrable Securities such Holder wishes to Register (a “Demand Registration”). Zoetis shall (i) within five (5) days of the receipt of such request, give written notice of such Demand Registration to all Holders of Registrable Securities (the “Zoetis Notice”), (ii) use its reasonable best efforts to file a Registration Statement in respect of such Demand Registration within forty-five (45) days of receipt of the request, and (iii) use its reasonable best efforts to cause such Registration Statement to become effective as expeditiously as possible. Zoetis shall include in such Registration all Registrable Securities that the Holders request to be included within the ten (10) days following their receipt of the Zoetis Notice.

(b) Limitations of Demand Registrations. There shall be no limitation on the number of Demand Registrations pursuant to Section 2.1(a); provided, however, that the Holders may not require Zoetis to effect more than two (2) Demand Registrations in a twelve (12)-month period (it being understood that the IPO Registration Statement shall not be treated as a Demand Registration). In the event that any Person shall have received rights to Demand Registrations pursuant to Section 2.7 or Section 3.3, and such Person shall have made a Demand Registration request, such request shall be treated as having been made by the Holder(s); provided, however, that if Pfizer and its Subsidiaries engage in up to three (3) related Private Debt Exchanges within any six (6)-month period following the date hereof, the Demand Registration requests made by the Participating Banks in such Private Debt Exchanges pursuant to its registration rights agreements with Zoetis shall collectively only count as one (1) Demand Registration for purposes of the limitation on the number of Demand Registration set forth in the first sentence of this Section 2.1(b) and such Demand Registration shall be deemed to have occurred upon the filing of the then most recent applicable Registration Statement; provided that the proceeding proviso shall not limit the number of Private Debt Exchanges that Pfizer and its Subsidiaries may engage in or the period over which they may engage in Private Debt Exchanges, but is solely intended to govern the treatment of such Private Debt Exchanges for purposes of the limitations on Demand Registrations in this Section 2.1(b). The Registrable Securities requested to be Registered pursuant to Section 2.1(a) must represent (i) an aggregate offering price of Registrable Securities that is reasonably be expected to equal at least $10,000,000 or (ii) all of the remaining Registrable Securities owned by the requesting Holder and its Affiliates.

(c) Effective Registration. Zoetis shall be deemed to have effected a Registration for purposes of Section 2.1(b) if the Registration Statement is declared effective by the SEC or becomes effective upon filing with the SEC, and remains effective until the earlier of (i) the date when all Registrable Securities thereunder have been sold and (ii) ninety (90) days from the effective date of the Registration Statement (the “Registration Period”). No Registration shall be deemed to have been effective if the conditions to closing specified in the underwriting agreement, if any, entered into in connection with such Registration are not satisfied by reason of Zoetis . If, during the Registration Period, such Registration is interfered with by any Registration Suspension, stop order, injunction or other order or requirement of the SEC or other Governmental Agency, the Registration Period shall be extended on a day-for-day basis for any period the Holder is unable to complete an offering as a result of such Registration Suspension, stop order, injunction or other order or requirement of the SEC or other Governmental Agency.

(d) Delay in Filing; Suspension of Registration. If the filing, initial effectiveness or continued use of a Registration Statement would, as reasonably determined in good faith by Zoetis, require the disclosure of material non-public information that Zoetis has a bona fide business purpose to keep confidential and the disclosure of which would have a material adverse effect on any active proposal by Zoetis or any of its Subsidiaries to engage in any material acquisition, merger, consolidation, tender offer, other business combination, reorganization or other material transaction, Zoetis may, upon giving prompt written notice of such action to the Holders, postpone the filing or effectiveness of such Registration (a “Registration Suspension”) for a period not to exceed thirty (30) days; provided, however, that Zoetis may exercise a Registration Suspension no more than two (2) times in any twelve (12)-month period. Notwithstanding the foregoing, no such delay shall exceed such number of days that Zoetis determines in good faith to be reasonably necessary. Zoetis shall (i) immediately notify the Holders upon the termination of any Registration Suspension, (ii) amend or supplement the Prospectus, if necessary, so it does not contain any untrue statement or omission therein and (iii) furnish to the Holders such numbers of copies of the Prospectus as so amended or supplemented as the Holders may reasonably request.

(e) Underwritten Offering. If the Initiating Holder so indicates at the time of its request pursuant to Section 2.1(a), such offering of Registrable Securities shall be in the form of an Underwritten Offering and Zoetis shall include such information in the Zoetis Notice. In the event that the Initiating Holder intends to distribute the Registrable Securities by means of an Underwritten Offering, the right of any Holder to include Registrable Securities in such Registration shall be conditioned upon such Holder’s participation in such underwriting and the inclusion of such Holder’s Registrable Securities in the underwriting.

(f) Priority of Securities in an Underwritten Offering. If the managing underwriter or underwriters of a proposed Underwritten Offering, including an Underwritten Offering from a Shelf Registration, pursuant to this Section 2.1 informs the Holders with Registrable Securities in the proposed Underwritten Offering in writing that, in its or their opinion, the number of securities requested to be included in such Underwritten Offering exceeds the number that can be sold in such Underwritten Offering without being likely to have an adverse effect on the price, timing or distribution of the securities offered or the market for the securities offered, then the securities to be included in such Underwritten Offering shall be reduced to such number that can be sold without such adverse effect and the securities to be included in such Underwritten Offering shall be: (i) first, Registrable Securities requested by Pfizer to be included in such Underwritten Offering; (ii) second, Registrable Securities requested by all other Holders to be included in such Underwritten Offering on a pro rata basis; and (iii) third, all other securities requested and otherwise eligible to be included in such Underwritten Offering (including securities to be sold for the account of Zoetis) on a pro rata basis.

(g) Shelf Registration. At any time after the date hereof when Zoetis is eligible to Register the applicable Registrable Securities on Form S-3 (or a successor form) and the Holder may request Demand Registrations, the requesting Holders may request Zoetis to effect a Demand Registration as a Shelf Registration. There shall be no limitations on the number of Underwritten Offerings pursuant to a Shelf Registration; provided, however, that the Holders may not require Zoetis to effect more than four (4) Underwritten Offerings in a twelve (12)-month period. Any Holder of Registrable Securities included on a Shelf Registration shall have the right to request that Zoetis cooperate in a shelf takedown at any time, including an Underwritten Offering, by delivering a written request thereof to Zoetis specifying the number of shares of Registrable Securities such Holder wishes to include in the shelf takedown (“Takedown Notice”). Zoetis shall (i) within five (5) days of the receipt of a Takedown Notice for an Underwritten Offering, give written notice of such Takedown Notice to all Holders of Registrable Securities included on such Shelf Registration (“Zoetis Takedown Notice”), and (ii) shall take all actions reasonably requested by such Holder, including the filing of a Prospectus supplement and the other actions described in Section 2.4, in accordance with the intended method of distribution set forth in the Takedown Notice as expeditiously as possible. If the takedown is an Underwritten Offering, Zoetis shall include in such Underwritten Offering all Registrable Securities that that the Holders request to be included within the two (2) days following their receipt of the Zoetis Takedown Notice. If the takedown is an Underwritten Offering, the Registrable Securities requested to be included in a shelf takedown must represent (i) an aggregate offering price of Registrable Securities that is reasonably be expected to equal at least $10,000,000 or (ii) all of the remaining Registrable Securities owned by the requesting Holder and its Affiliates.

(h) SEC Form. Except as set forth in the next sentence, Zoetis shall use its reasonable best efforts to cause Demand Registrations to be Registered on Form S-3 (or any successor form), and if Zoetis is not then eligible under the Securities Act to use Form S-3, Demand Registrations shall be Registered on Form S-1 (or any successor form). If a Demand Registration is a Convertible or Exchange Registration, Zoetis shall effect such Registration on the appropriate Form under the Securities Act for such Registrations. Zoetis shall use its reasonable best efforts to become eligible to use Form S-3 and, after becoming eligible to use Form S-3, shall use its reasonable best efforts to remain so eligible. All Demand Registrations shall comply with applicable requirements of the Securities Act and, together with each Prospectus included, filed or otherwise furnished by Zoetis in connection therewith, shall not contain any untrue statement of material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading.

2.2 Piggyback Registrations.

(a) Participation. If Zoetis proposes to file a Registration Statement under the Securities Act with respect to any offering of Zoetis Common Stock for its own account and/or for the account of any other Persons (other than a Registration (i) under Section 2.1 hereof, (ii) pursuant to a Registration Statement on Form S-8 or Form S-4 or similar form that relates to a transaction subject to Rule 145 under the Securities Act, (iii) pursuant to any form that does not include substantially the same information as would be required to be included in a Registration Statement covering the sale of Registrable Securities, (iv) in connection with any dividend reinvestment or similar plan, (v) for the sole purpose of offering securities to another entity or its security holders in connection with the acquisition of assets or securities of such entity or any similar transaction or (vi) in which the only Zoetis Common Stock being Registered is Zoetis Common Stock issuable upon conversion of debt securities that are also being Registered) (a “Zoetis Public Sale”), then, as soon as practicable (but in no event less than fifteen (15) days prior to the proposed date of filing such Registration Statement), Zoetis shall give written notice of such proposed filing to each Holder, and such notice shall offer such Holders the opportunity to Register under such Registration Statement such number of Registrable Securities as each such Holder may request in writing (a “Piggyback Registration”). Subject to Section 2.2(a) and Section 2.2(c), Zoetis shall include in such Registration Statement all such Registrable Securities that are requested to be included therein within fifteen (15) days after the receipt of any such notice; provided, however, that if, at any time after giving written notice of its intention to Register any securities and prior to the effective date of the Registration Statement filed in connection with such Registration, Zoetis shall determine for any reason not to Register or to delay Registration of such securities, Zoetis may, at its election, give written notice of such determination to each such Holder and, thereupon, (i) in the case of a determination not to Register, shall be relieved of its obligation to Register any Registrable Securities in connection with such Registration, without prejudice, however, to the rights of any Holder to request that such Registration be effected as a Demand Registration under Section 2.1, and (ii) in the case of a determination to delay Registration, shall be permitted to delay Registering any Registrable Securities for the same period as the delay in Registering such other shares of Zoetis Common Stock. No Registration effected under this Section 2.2 shall relieve Zoetis of its obligation to effect any Demand Registration under Section 2.1. If the offering pursuant to a Registration Statement pursuant to this Section 2.2 is to be an Underwritten Offering, then each Holder making a request for a Piggyback Registration pursuant to this Section 2.2(a) shall, and Zoetis shall use reasonable best efforts to coordinate arrangements with the underwriters so that each such Holder may, participate in such Underwritten Offering. If the offering pursuant to such Registration Statement is to be on any other basis, then each Holder making a request for a Piggyback Registration pursuant to this Section 2.2(a) shall, and Zoetis shall use reasonable best efforts to coordinate arrangements so that each such Holder may, participate in such offering on such basis. Zoetis’s filing of a Shelf Registration shall not be deemed to be a Zoetis Public Sale; provided, however, that the proposal to file any Prospectus supplement filed pursuant to a Shelf Registration with respect to an offering of Zoetis Common Stock for its own account and/or for the account of any other Persons will be a Zoetis Public Sale unless such offering qualifies for an exemption from Zoetis Public Sale definition in this Section 2.2(a); provided, further that if Zoetis files a Shelf Registration for its own account and/or for the account of any other Persons, Zoetis agrees that it shall use its reasonable best efforts to include in such Registration Statement such disclosures as may be required by Rule 430B under the Securities Act in order to ensure that the Holders may be added to such Shelf Registration at a later time through the filing of a Prospectus supplement rather than a post-effective amendment.

(b) Right to Withdraw. Each Holder shall have the right to withdraw such Holder’s request for inclusion of its Registrable Securities in any Underwritten Offering pursuant to this Section 2.2 at any time prior to the execution of an underwriting agreement with respect thereto by giving written notice to Zoetis of such Holder’s request to withdraw and, subject to the preceding clause, each Holder shall be permitted to withdraw all or part of such Holder’s Registrable Securities from a Piggyback Registration at any time prior to the effective date thereof.

(c) Priority of Piggyback Registration. If the managing underwriter or underwriters of any proposed Underwritten Offering of a class of Registrable Securities included in a Piggyback Registration informs Zoetis and the Holders in writing that, in its or their opinion, the number of securities of such class which such Holder and any other Persons intend to include in such Underwritten Offering exceeds the number which can be sold in such Underwritten Offering without being likely to have an adverse effect on the price, timing or distribution of the securities offered or the market for the securities offered, then the securities to be included in such Underwritten Offering shall be reduced to such number that can be sold without such adverse effect and the securities to be included in the Underwritten Offering shall be (i) first, all securities of Zoetis or any other Persons for whom Zoetis is effecting the Underwritten Offering, as the case may be, proposes to sell; (ii) second, Registrable Securities requested by Pfizer to be included in such Underwritten Offering; (iii) third, Registrable Securities requested by all other Holders to be included in such Underwritten Offering on a pro rata basis; and (iv) forth, all other securities requested and otherwise eligible to be included in such Underwritten Offering (including securities to be sold for the account of Zoetis) on a pro rata basis.

“Blue Sky” laws of each state and other jurisdiction of the United States as any selling Holder or managing underwriter or underwriters, if any, or their respective counsel reasonably request in writing and do any and all other acts or things reasonably necessary or advisable to keep such registration or qualification in effect for so long as such Registration Statement remains in effect and so as to permit the continuance of sales and dealings in such jurisdictions of the United States for so long as may be necessary to complete the distribution of the Registrable Securities covered by the Registration Statement; provided that Zoetis will not be required to qualify generally to do business in any jurisdiction where it is not then so qualified or to take any action which would subject it to taxation or general service of process in any such jurisdiction where it is not then so subject;

(xii) in connection with any sale of Registrable Securities that will result in such securities no longer being Registrable Securities, cooperate with each selling Holder and the managing underwriter or underwriters, if any, to facilitate the timely preparation and delivery of certificates representing Registrable Securities to be sold and not bearing any restrictive Securities Act legends; and to register such Registrable Securities in such denominations and such names as such selling Holder or the underwriter(s), if any, may request at least two (2) Business Days prior to such sale of Registrable Securities; provided that Zoetis may satisfy its obligations hereunder without issuing physical stock certificates through the use of the Depository Trust Company’s Direct Registration System;

(xiii) cooperate and assist in any filings required to be made with the Financial Industry Regulatory Authority and each securities exchange, if any, on which any of Zoetis’s securities are then listed or quoted and on each inter-dealer quotation system on which any of Zoetis’s securities are then quoted, and in the performance of any due diligence investigation by any underwriter (including any “qualified independent underwriter”) that is required to be retained in accordance with the rules and regulations of each such exchange, and use its reasonable best efforts to cause the Registrable Securities covered by the applicable Registration Statement to be registered with or approved by such other governmental agencies or authorities as may be necessary to enable the seller or sellers thereof or the underwriter or underwriters, if any, to consummate the disposition of such Registrable Securities;

(xiv) not later than the effective date of the applicable Registration Statement, provide a CUSIP number for all Registrable Securities and provide the applicable transfer agent with printed certificates for the Registrable Securities which are in a form eligible for deposit with The Depository Trust Company; provided that Zoetis may satisfy its obligations hereunder without issuing physical stock certificates through the use of the Depository Trust Company’s Direct Registration System;

(xv) obtain for delivery to and addressed to each selling Holder and to the underwriter or underwriters, if any, opinions from outside counsel and the general counsel or deputy general counsel for Zoetis, in each case dated the effective date of the Registration Statement or, in the event of an Underwritten Offering, the date of the closing under the underwriting agreement, and in each such case in customary form and content for the type of Underwritten Offering;

(xvi) in the case of an Underwritten Offering, obtain for delivery to and addressed to Zoetis and the underwriter or underwriters and, to the extent requested, each selling Holder, a cold comfort letter from Zoetis’s independent certified public accountants in customary form and content for the type of Underwritten Offering, dated the date of execution of the underwriting agreement and brought down to the closing under the underwriting agreement;

(xvii) use its reasonable best efforts to comply with all applicable rules and regulations of the SEC and make generally available to its security holders, as soon as reasonably practicable, but no later than ninety (90) days after the end of the twelve (12)-month period beginning with the first day of Zoetis’s first quarter commencing after the effective date of the applicable Registration Statement, an earnings statement satisfying the provisions of Section 11(a) of the Securities Act and the rules and regulations promulgated thereunder and covering the period of at least twelve (12) months, but not more than eighteen (18) months, beginning with the first month after the effective date of the Registration Statement;

(xviii) provide and cause to be maintained a transfer agent and registrar for all Registrable Securities covered by the applicable Registration Statement from and after a date not later than the effective date of such Registration Statement;

(xix) cause all Registrable Securities covered by the applicable Registration Statement to be listed on each securities exchange on which any of Zoetis’s securities are then listed or quoted and on each inter-dealer quotation system on which any of Zoetis’s securities are then quoted;

(xx) provide (A) each Holder participating in the Registration, (B) the underwriters (which term, for purposes of this Agreement, shall include a Person deemed to be an underwriter within the meaning of Section 2(11) of the Securities Act), if any, of the Registrable Securities to be Registered, (C) the sale or placement agent therefor, if any, (D) counsel for such underwriters or agent, and (E) any attorney, accountant or other agent or representative retained by such Holder or any such underwriter, as selected by such Holder, the opportunity to participate in the preparation of such Registration Statement, each Prospectus included therein or filed with the SEC, and each amendment or supplement thereto, and to require the insertion therein of material, furnished to Zoetis in writing, which in the reasonable judgment of such Holder(s) and their counsel should be included; and for a reasonable period prior to the filing of such Registration Statement, make available upon reasonable notice at reasonable times and for reasonable periods for inspection by the parties referred to in (A) through (E) above, all pertinent financial and other records, pertinent corporate documents and properties of Zoetis that are available to Zoetis, and cause all of Zoetis’s officers, directors and employees and the independent public accountants who have certified its financial statements to make themselves available at reasonable times and for reasonable periods to discuss the business of Zoetis and to supply all information available to Zoetis reasonably requested by any such Person in connection with such Registration Statement as shall be necessary to enable them to exercise their due diligence responsibility, subject to the foregoing;

(xxi) to cause the executive officers of Zoetis to participate in the customary “road show” presentations that may be reasonably requested by the managing underwriter or underwriters in any Underwritten Offering and otherwise to facilitate, cooperate with, and participate in each proposed offering contemplated herein and customary selling efforts related thereto; and

(xxii) take all other customary steps reasonably necessary to effect the Registration, offering and sale of the Registrable Securities.

(b) As a condition precedent to any Registration hereunder, Zoetis may require each Holder as to which any Registration is being effected to furnish to Zoetis such information regarding the distribution of such securities and such other information relating to such Holder, its ownership of Registrable Securities and other matters as Zoetis may from time to time reasonably request in writing. Each such Holder agrees to furnish such information to Zoetis and to cooperate with Zoetis as reasonably necessary to enable Zoetis to comply with the provisions of this Agreement.

(c) Pfizer agrees, and any other Holder agrees by acquisition of such Registrable Securities, that, upon receipt of any written notice from Zoetis of the occurrence of any event of the kind described in Section 2.4(a)(vi), such Holder will forthwith discontinue disposition of Registrable Securities pursuant to such Registration Statement until such Holder’s receipt of the copies of the supplemented or amended Prospectus contemplated by Section 2.4(a)(vi), or until such Holder is advised in writing by Zoetis that the use of the Prospectus may be resumed, and if so directed by Zoetis, such Holder will deliver to Zoetis (at Zoetis’s expense) all copies, other than permanent file copies then in such Holder’s possession, of the Prospectus covering such Registrable Securities current at the time of receipt of such notice. In the event Zoetis shall give any such notice, the period during which the applicable Registration Statement is required to be maintained effective shall be extended by the number of days during the period from and including the date of the giving of such notice to and including the date when each seller of Registrable Securities covered by such Registration Statement either receives the copies of the supplemented or amended Prospectus contemplated by Section 2.4(a)(vi) or is advised in writing by Zoetis that the use of the Prospectus may be resumed.

2.5 Holdback Agreements. To the extent requested in writing by the managing underwriter or underwriters of any Underwritten Offering, Zoetis agrees not to, and shall exercise commercially reasonable efforts to obtain agreements (in the underwriters’ customary form) from its directors, executive officers and beneficial owners of five percent (5%) or more of Zoetis Common Stock not to, directly or indirectly offer, sell, pledge, contract to sell (including any short sale), grant any option to purchase or otherwise dispose of any equity securities of Zoetis or enter into any hedging transaction relating to any equity securities of Zoetis during the ninety (90) days beginning on pricing date of such Underwritten Offering (except as part of such Underwritten Offering or any Distribution or pursuant to registrations on Form S-8 or S-4 or any successor forms thereto) unless the managing underwriter or underwriters otherwise agrees to a shorter period.

2.6 Underwriting Agreement in Underwritten Offerings. If requested by the managing underwriters for any Underwritten Offering, Zoetis shall enter into an underwriting agreement with such underwriters for such offering; provided, however, that no Holder shall be required to make any representations or warranties to Zoetis or the underwriters (other than representations and warranties regarding such Holder and such Holder’s intended method of distribution) or to undertake any indemnification obligations to Zoetis or the underwriters with respect thereto, except as otherwise provided in Section 2.10 hereof.

2.7 Private Debt Exchange. If Pfizer decides to engage in a Private Debt Exchange with one or more Participating Banks, Zoetis agrees that it will enter into a registration rights agreement with the Participating Banks at the time of such Private Debt Exchange on terms and conditions consistent with this Agreement and reasonably satisfactory to Zoetis. In addition, Zoetis shall execute and deliver all additional documents, agreements and instruments and shall take any and all actions reasonably requested by Pfizer in connection with any Private Debt Exchange.

2.8 Convertible or Exchange Registration. If any Holder of Registrable Securities offers any options, rights, warrants or other securities issued by it or any other Person that are offered with, convertible into or exercisable or exchangeable for any Registrable Securities, the Registrable Securities underlying such options, rights, warrants or other securities shall be eligible for Registration pursuant to Section 2.1 and Section 2.2 hereof (a “Convertible or Exchange Registration”).

2.9 Registration Expenses Paid By Company. In the case of any Registration of Registrable Securities required pursuant to this Agreement (including any Registration that is delayed or withdrawn) or proposed Underwritten Offering pursuant to this Agreement, Zoetis shall pay all Registration Expenses regardless of whether the Registration Statement becomes effective or the Underwritten Offering is completed.

2.10 Indemnification.

(a) Indemnification by Company. Zoetis agrees to indemnify and hold harmless, to the full extent permitted by law, each Holder, such Holder’s Affiliates and their respective officers, directors, employees, advisors, and agents and each Person who controls (within the meaning of the Securities Act or the Exchange Act) such Persons from and against any and all losses, claims, damages, liabilities (or actions in respect thereof, whether or not such indemnified party is a party thereto) and expenses, joint or several (including reasonable costs of investigation and legal expenses) (each, a “Loss” and collectively “Losses”) arising out of or based upon (i) any untrue or alleged untrue statement of a material fact contained in any Registration Statement under which the sale of such Registrable Securities was Registered under the Securities Act (including any final or preliminary Prospectus contained therein or any amendment thereof or supplement thereto or any documents incorporated by reference therein), or any such statement made in any free writing prospectus (as defined in Rule 405 under the Securities Act) that Zoetis has filed or is required to file pursuant to Rule 433(d) of the Securities Act, (ii) any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein (in the case of a Prospectus, preliminary Prospectus or free writing prospectus, in light of the circumstances under which they were made) not misleading; provided, however, that Zoetis shall not be liable to any particular indemnified party in any such case to the extent that any such Loss arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in any such Registration Statement (i) in reliance upon and in conformity with written information furnished to Zoetis by such indemnified party expressly for use in the preparation thereof or (ii) which has been corrected in a subsequent applicable filing with the SEC but such indemnified party nonetheless failed to provide such corrected filing to the Person asserting such Loss, in breach of the indemnified party’s obligations under applicable law. This indemnity shall be in addition to any liability Zoetis may otherwise have. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of such Holder or any indemnified party and shall survive the transfer of such securities by such Holder.

(b) Indemnification by the Selling Holder. Each selling Holder agrees (severally and not jointly) to indemnify and hold harmless, to the full extent permitted by law, Zoetis, its directors, officers, employees, advisors, and agents and each Person who controls Zoetis (within the meaning of the Securities Act and the Exchange Act) from and against any Losses arising out of or based upon (i) any untrue or alleged untrue statement of a material fact contained in any Registration Statement under which the sale of such Registrable Securities was Registered under the Securities Act (including any final or

preliminary Prospectus contained therein or any amendment thereof or supplement thereto or any documents incorporated by reference therein), or any such statement made in any free writing prospectus that Zoetis has filed or is required to file pursuant to Rule 433(d) of the Securities Act, or (ii) any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein (in the case of a Prospectus, preliminary Prospectus or free writing prospectus, in light of the circumstances under which they were made) not misleading to the extent, but, in each case (i) or (ii), only to the extent, that such untrue statement or omission is contained in any information furnished in writing by such selling Holder to Zoetis specifically for inclusion in such Registration Statement, Prospectus, preliminary Prospectus or free writing prospectus and has not been corrected in a subsequent applicable filing with the SEC provided to the Person asserting such Loss prior to or concurrently with the sale of the Registrable Securities to such Person. In no event shall the liability of any selling Holder hereunder be greater in amount than the dollar amount of the net proceeds received by such Holder under the sale of the Registrable Securities giving rise to such indemnification obligation. This indemnity shall be in addition to any liability the selling Holder may otherwise have. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of Zoetis or any indemnified party.

(c) Conduct of Indemnification Proceedings. Any Person entitled to indemnification hereunder will (i) give prompt written notice to the indemnifying party of any claim with respect to which it seeks indemnification (provided that any delay or failure to so notify the indemnifying party shall relieve the indemnifying party of its obligations hereunder to the extent that it is materially prejudiced by reason of such delay or failure) and (ii) permit such indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party; provided, however, that any Person entitled to indemnification hereunder shall have the right to select and employ separate counsel and to participate in the defense of such claim, but the fees and expenses of such counsel shall be at the expense of such Person unless (i) the indemnifying party has agreed in writing to pay such fees or expenses, (ii) the indemnifying party shall have failed to assume the defense of such claim within a reasonable time after receipt of notice of such claim from the Person entitled to indemnification hereunder and employ counsel reasonably satisfactory to such Person, (iii) the indemnified party has reasonably concluded (based on advice of counsel) that there may be legal defenses available to it or other indemnified parties that are different from or in addition to those available to the indemnifying party, or (iv) in the reasonable judgment of any such Person, based upon advice of its counsel, a conflict of interest may exist between such Person and the indemnifying party with respect to such claims (in which case, if the Person notifies the indemnifying party in writing that such Person elects to employ separate counsel at the expense of the indemnifying party, the indemnifying party shall not have the right to assume the defense of such claim on behalf of such Person). If such defense is not assumed by the indemnifying party, the indemnifying party will not be subject to any liability for any settlement made without its consent, but such consent may not be unreasonably withheld, conditioned or delayed. If the indemnifying party assumes the defense, the indemnifying party shall not have the right to settle such action without the consent of the indemnified party, which consent may not be unreasonably withheld, conditioned or delayed. No indemnifying party shall consent to entry of any judgment or enter into any settlement which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of an unconditional release from all liability in respect to such claim or litigation. It is understood that the indemnifying party or parties shall not, in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the reasonable fees, disbursements and other charges of more than one separate firm admitted to practice in such jurisdiction at any one time from all such indemnified party or parties unless (x) the employment of more than one counsel has been authorized in writing by the indemnified party or parties, (y) an indemnified party has reasonably concluded (based on advice of counsel) that there may be legal defenses available to it that are different from or in addition to those available to the other indemnified parties or (z) a conflict or potential conflict exists or may exist (based on advice of counsel to an indemnified party) between such indemnified party and the other indemnified parties, in each of which cases the indemnifying party shall be obligated to pay the reasonable fees and expenses of such additional counsel or counsels.

(d) Contribution. If for any reason the indemnification provided for in Section 2.10(a) or Section 2.10(b) is unavailable to an indemnified party or insufficient to hold it harmless as contemplated by Section 2.10(a) or Section 2.10(b), then the indemnifying party shall contribute to the amount paid or payable by the indemnified party as a result of such Loss in such proportion as is appropriate to reflect the relative fault of the indemnifying party on the one hand and the indemnified party on the other hand. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the indemnifying party or the indemnified party and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. Notwithstanding anything in this Section 2.10(d) to the contrary, no indemnifying party (other than Zoetis) shall be required pursuant to this Section 2.10(d) to contribute any amount in excess of the amount by which the net proceeds received by such indemnifying party from the sale of Registrable Securities in the offering to which the Losses of the indemnified parties relate (before deducting expenses, if any) exceeds the amount of any damages which such indemnifying party has otherwise been required to pay by reason of such untrue statement or omission. The parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 2.10(d) were determined by pro rata allocation or by any other method of allocation that does not take account of the equitable

considerations referred to in this Section 2.10(d). No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation. The amount paid or payable by an indemnified party hereunder shall be deemed to include, for purposes of this Section 2.10(d), any legal or other expenses reasonably incurred by such indemnified party in connection with investigating, preparing to defend or defending against or appearing as a third party witness in respect of, or otherwise incurred in connection with, any such loss, claim, damage, expense, liability, action, investigation or proceeding. If indemnification is available under this Section 2.10, the indemnifying parties shall indemnify each indemnified party to the full extent provided in Section 2.10(a) and Section 2.10(b) hereof without regard to the relative fault of said indemnifying parties or indemnified party.

2.11 Reporting Requirements; Rule 144. Zoetis shall use its reasonable best efforts to be and remain in compliance with the periodic filing requirements imposed under the SEC’s rules and regulations, including the Exchange Act, and any other applicable laws or rules, and thereafter shall timely file such information, documents and reports as the SEC may require or prescribe under Section 13 or 15(d) (whichever is applicable) of the Exchange Act. If Zoetis is not required to file such reports during such period, it will, upon the request of any Holder, make publicly available such necessary information for so long as necessary to permit sales pursuant to Rule 144 or Regulation S under the Securities Act, and it will take such further action as any Holder may reasonably request, all to the extent required from time to time to enable such Holder to sell Registrable Securities without Registration under the Securities Act within the limitation of the exemptions provided by (a) Rule 144 or Regulation S under the Securities Act, as such Rules may be amended from time to time, or (b) any rule or regulation hereafter adopted by the SEC. From and after the date hereof through the first anniversary of the date upon which no Holder owns any Registrable Securities, Zoetis shall forthwith upon request furnish any Holder (i) a written statement by Zoetis as to whether it has complied with such requirements and, if not, the specifics thereof, (ii) a copy of the most recent annual or quarterly report of Zoetis, and (iii) such other reports and documents filed by Zoetis with the SEC as such Holder may reasonably request in availing itself of an exemption for the sale of Registrable Securities without registration under the Securities Act.

2.12 Other Registration Rights. Zoetis shall not grant to any Persons the right to request Zoetis to Register any equity securities of Zoetis, or any securities convertible or exchangeable into or exercisable for such securities, whether pursuant to “demand,” “piggyback,” or other rights, unless such rights are subject and subordinate to the rights of the Holders under this Agreement.

3.1 Term. This Agreement shall terminate upon such time as there are no Registrable Securities, except for the provisions of Section 2.9 and Section 2.10 and all of this Article III, which shall survive any such termination.

3.2 Notices. All notices or other communications under this Agreement shall be in writing and shall be deemed to be duly given when (a) delivered in person or (b) deposited in the United States mail or private express mail, postage prepaid, addressed as follows:

Any party may, by notice to the other party, change the address to which such notices are to be given.

3.3 Successors, Assigns and Transferees. This Agreement and all provisions hereof shall be binding upon and inure to the benefit of the parties hereto and their respective successors and permitted assigns. Zoetis may assign this Agreement at any time in connection with a sale or acquisition of Zoetis, whether by merger, consolidation, sale of all or substantially all of Zoetis’s assets, or similar transaction, without the consent of the Holders; provided that the successor or acquiring Person agrees in writing to assume all of Zoetis’s rights and obligations under this Agreement. A Holder may assign its rights and obligations under this Agreement to any transferee that acquires at least five percent (5%) of the number of Registrable Securities beneficially owned by Pfizer immediately following the completion of the IPO and executes an agreement to be bound hereby in the form attached hereto as Exhibit A, an executed counterpart of which shall be furnished to Zoetis. Notwithstanding the foregoing, if such transfer is subject to covenants, agreements or other undertakings restricting transferability thereof, the Registration Rights shall not be transferred in connection with such transfer unless such transferee complies with all such covenants, agreements and other undertaking.

3.4 GOVERNING LAW; NO JURY TRIAL.

(a) This Agreement shall be governed by and construed and interpreted in accordance with the laws of the State of New York, without regard to the conflict of laws principles thereof that would result in the application of any law other than the laws of the State of New York. EACH OF THE PARTIES HEREBY WAIVES TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY WITH RESPECT TO ANY COURT PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF AND PERMITTED UNDER OR IN CONNECTION WITH THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT. EACH OF THE PARTIES HEREBY (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF THE OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT AND THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT, AS APPLICABLE.

(b) With respect to any Action relating to or arising out of this Agreement, each party to this Agreement irrevocably (a) consents and submits to the exclusive jurisdiction of the courts of the State of New York and any court of the United States located in the Borough of Manhattan in New York City; (b) waives any objection which such party may have at any time to the laying of venue of any Action brought in any such court, waives any claim that such Action has been brought in an inconvenient forum and further waives the right to object, with respect to such Action, that such court does not have jurisdiction over such party; and (c) consents to the service of process at the address set forth for notices in Section 3.2 herein; provided, however, that such manner of service of process shall not preclude the service of process in any other manner permitted under applicable law.

3.5 Specific Performance. In the event of any actual or threatened default in, or breach of, any of the terms, conditions and provisions of this Agreement, the party or parties who are or are to be thereby aggrieved shall have the right to seek specific performance and injunctive or other equitable relief of its rights under this Agreement, in addition to any and all other rights and remedies at law or in equity, and all such rights and remedies shall be cumulative.

3.6 Headings. The article, section and paragraph headings contained in this Agreement are for reference purposes only and shall not affect in any way the meaning or interpretation of this Agreement.

3.7 Severability. If any provision of this Agreement or the application thereof to any Person or circumstance is determined by a court of competent jurisdiction to be invalid, void or unenforceable, the remaining provisions hereof or the application of such provision to Persons or circumstances or in jurisdictions other than those as to which it has been held invalid or unenforceable, shall remain in full force and effect and shall in no way be affected, impaired or

invalidated thereby, so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner adverse to any party. Upon such determination, the parties shall negotiate in good faith in an effort to agree upon such a suitable and equitable provision to effect the original intent of the parties.

3.8 Amendment; Waiver.

(a) This Agreement may not be amended or modified and waivers and consents to departures from the provisions hereof may not be given, except by an instrument or instruments in writing making specific reference to this Agreement and signed by Zoetis and the Holders of a majority of the Registrable Securities; provided that if Pfizer or any of its Affiliates owns Registrable Securities, no amendment to or waiver of any provision in this Agreement will be effected without the written consent of Pfizer if such amendment or waiver adversely affects the rights of Pfizer or such Affiliates of Pfizer.

(b) Waiver by any party of any default by the other party of any provision of this Agreement shall not be deemed a waiver by the waiving party of any subsequent or other default, nor shall it prejudice the rights of the other party.

3.9 Further Assurances. Each of the parties hereto shall execute and deliver all additional documents, agreements and instruments and shall do any and all acts and things reasonably requested by the other party hereto in connection with the performance of its obligations undertaken in this Agreement.

3.10 Counterparts. This Agreement may be executed in one or more counterparts, all of which shall be considered one and the same agreement, and shall become effective when one or more counterparts have been signed by each of the parties and delivered to the other party. Execution of this Agreement or any other documents pursuant to this Agreement by facsimile or other electronic copy of a signature shall be deemed to be, and shall have the same effect as, executed by an original signature.
