Notwithstanding the foregoing, in the event that a scheduled Short-Term Payout, if paid, would (or in the judgment of the Committee, would be reasonably likely to) result in the loss of deductibility for federal income tax purposes of any compensation paid by the Company due to the limitations of Section 162(m) of the Code in any Plan Year, then the scheduled Short-Term Payout shall be delayed to the earlier of (i) the date the Committee reasonably determines that the deduction of payment of the Short-Term Payout would not be limited or eliminated by application of Section 162(m) of the Code or (ii) the calendar year in which the Participant Separates from Service.

7.2    Retirement Benefit.

(a)    Form of Distribution of Retirement Benefit. A Participant’s Retirement Benefit may be paid in either a lump sum (“Lump Sum Retirement Benefit”) on a Retirement Benefit Lump Sum Payout Date elected by the Participant or in quarterly or yearly installment payments (“Installment Retirement Benefit”) on Retirement Benefit Installment Payout Dates elected by the Participant. The Participant’s Retirement Benefit payments shall be made in accordance with the Administrative Procedures as soon as practicable after the applicable Retirement Benefit Lump Sum Payout Date or Retirement Benefit Installment Payout Dates elected by the Participant on the applicable Election Form; provided, however, that in no event shall such payments be made later than 30 days after the relevant elected dates.

(b)    Installment Payments for Retirement Benefits Allocated to Investment Options (Other than the Market Interest Option). The amount of each installment payment with respect to the portion of a Deferral Account that is allocated to an Investment Option (other than the Market Interest Option) shall be determined by the Yearly Installment Method, if the Participant elected to receive annual installments or the Quarterly Installment Method, if the Participant elected to receive quarterly installments.

(c)    Installment Payments for Retirement Benefits Allocated to the Market Interest Option. The amount of each installment payment with respect to the portion of a Deferral

Account that is allocated to the Market Interest Option shall be determined by the following annuity methodology. The amount of each installment payment shall be calculated by the Administrative Record Keeper as an annuity at the beginning of the installment payout period elected by the Participant and shall be recalculated each time there is a change in the Market Rate or the Participant transfers an amount into or out of the Market Interest Option, based on: (i) the balance of the applicable portion of the Participant’s Deferral Account that is allocated to the Market Interest Option (adjusted to reflect interest at the Market Rate then in effect in accordance with clause (iii)) immediately following the date of the change in the Market Rate or the Participant’s transfer as applicable, (ii) the number of remaining installments, (iii) the Market Rate in effect at the time of the calculation (assuming that the Market Rate will remain unchanged throughout the payout period), and (iv) a final value of the portion of the Participant’s Deferral Account allocated to the Market Interest Option of zero dollars ($0).

7.3    Payment Upon Separation from Service. Subject to Section 7.6 below, and notwithstanding anything in the Plan to the contrary, in the event a Participant incurs a Separation from Service with the Company for reasons other than Retirement or death (including a Separation from Service as a result of Disability by a Participant who is Retirement Eligible), or in the event that any Subsidiary that employs a Participant ceases to be a wholly-owned Subsidiary of Wyeth, the entire balance of the Participant’s Deferral Account shall be distributed to the Participant in a single lump sum within 90 days thereafter.

7.4    Payment Upon Death. Notwithstanding anything in the Plan to the contrary, in the event a Participant dies prior to the receipt of any or all of his or her Deferral Account, the balance of such account shall be distributed in a single lump sum to the Participant’s Beneficiary(ies) as soon as practicable following the Participant’s death, but in no event later than the later of (x) December 31 of the calendar year in which the death occurs or (y) the 15^th day of the third calendar month following the Participant’s death.

7.5    Distribution of an Unforeseeable Emergency.

(a)In General. A Participant may receive a distribution with respect to his Deferral Account, at such time as the Committee determines that the Participant or his Beneficiary has incurred an Unforeseeable Emergency. Distribution because of an Unforeseeable Emergency must be limited to the amount reasonably necessary to satisfy the Unforeseeable Emergency and shall be permitted only if the Unforeseeable Emergency may not be relieved through reimbursement from insurance or otherwise, by liquidation of the Participant’s assets, to the extent the liquidation of such assets would not cause severe financial hardship to the Participant or by cessation of deferrals by the Participant in the Plan and the SESP. If a Participant demonstrates that an Unforeseeable Emergency has occurred, the Committee shall first cancel the Participant’s deferral election for the remainder of the Plan Year under the Plan and the SESP. If the Participant demonstrates, and the Committee shall determine, that a cancellation of a Participant’s deferral election under the Plan and the SESP for the balance of the Plan Year will not alleviate or remedy the Participant’s or his Beneficiary’s Unforeseeable Emergency, then, in addition to the cancellation of the Participant’s deferral election, the Committee may authorize a distribution from the balance in the Participant’s Deferral Account in the amount deemed

necessary by the Committee to alleviate or remedy the Participant’s or his Beneficiary’s Unforeseeable Emergency. A distribution under this Section 7.5 shall be applied proportionately among the sub-accounts included in the Participant’s Deferral Account.

(b)Cancellation of Deferrals. In the event of a cancellation of deferrals pursuant to Section 7.5(a), the Participant’s election shall be cancelled, and not postponed or otherwise delayed, such that any later deferral election will be subject to the provisions governing deferral elections as provided in Section 4.

7.6    Six-Month Delay in Commencement of 409A Benefits. Notwithstanding any distribution election made by a Participant, if, at the time of a Participant’s Separation from Service, the Participant is a Key Employee, then, solely to the extent necessary for Section 409A Compliance, any amounts payable to the Participant under the Plan with respect to his Deferral Account during the period beginning on the date of the Participant’s Separation from Service and ending on the six-month anniversary of such date (the “Delayed Payment Amount”) shall be delayed and not paid to the Participant until the first Business Day following such six-month anniversary date, at which time such delayed amounts shall be paid to the Participant in a lump-sum. If payment of an amount is delayed as a result of this Section 7.6, such amount shall continue to be deemed invested in the Investment Options selected by the Participant from the date on which such amount would otherwise have been paid to the Participant but for this Section 7.6 to the day immediately prior to the date the Delayed Payment Amount is paid. If a Participant dies on or after the date of the Participant’s Separation from Service and prior to payment of the Delayed Payment Amount, any amount delayed pursuant to this Section 7.6 shall be paid to the Participant’s Beneficiary, together with any interest credited thereon, on the last Business Day of the month following the date of such Participant’s death or as soon as administratively practicable thereafter.

8.1    Redeferrals of the Deferral Account. A Participant shall be permitted to elect, prior to his Retirement, to redefer all or a portion of the amounts deferred under the Plan in accordance with the provisions of this Section 8. A Participant shall be permitted to make separate redeferral elections with respect to each of his Base Salary or Bonus Compensation deferrals, and each of his elections to defer or redefer all or a portion of the ERP 409A Benefit, the SERP 409A Benefit or the SESP 409A Account to be rolled over to the Plan in a Valid Notional Rollover in accordance with the ERP, the SERP or the SESP, as the case may be. A Retirement Benefit payable in the form of a Retirement Benefit Installment Payout shall be treated as a “single” payment and each separately identified amount to which the Participant is entitled shall be considered a separate payment.

8.2    Redeferral of Short-Term Payout Amounts. A Participant who has not yet had a Separation from Service may elect to redefer each Short-Term Payout payable on a Short-Term Payout Date to another allowable Short-Term Payout Date or to convert such Short-Term Payout to a Retirement Benefit and receive payout of such amounts on a Retirement Benefit Lump Sum Payout Date or a Retirement Benefit Installment Payout Date, provided, however, that:

(a)    The election to redefer must be made and become irrevocable (other than in the case of the death of the Participant) at least one year prior to the Short-Term Payout Date;

(b)    The election shall not become effective for at least one year after the election is made; and

(c)    The Short-Term Payout Date, the Retirement Benefit Lump Sum Payout Date or the date of the first Retirement Benefit Installment Payout shall not be earlier than the fifth anniversary of the Short-Term Payout Date elected by the Participant pursuant to the election in effect immediately prior to such redeferral.

8.3    Redeferral of Retirement Benefits. A Participant may, prior to his Retirement, elect to redefer a Retirement Benefit to another Retirement Benefit Lump Sum Payout Date or Retirement Benefit Installment Payout Dates, provided, however, that:

(a)    The election to redefer must be made and become irrevocable (other than in the case of the death of the Participant) at least one year prior to the original Retirement Benefit Lump Sum Payout Date or the original initial Retirement Benefit Installment Payout Date;

(b)    The election shall not become effective for at least one year after the election is made; and

(c)    The Retirement Benefit Lump Sum Payout Date or the date of the first Retirement Benefit Installment Payout Date shall not be earlier than the fifth anniversary of the Retirement

Benefit Lump Sum Payout Date or the initial Retirement Benefit Installment Payout Date, as the case may be, elected by the Participant pursuant to the election in effect immediately prior to such redeferral.

8.4    Limitations on Redeferrals. Notwithstanding the foregoing provisions of this Section 8, no Participant shall be permitted to redefer his Deferral Account following his Retirement.

9.1    General. If a Participant or his Beneficiary or the authorized representative of one of the foregoing (hereinafter, the “Claimant”) does not receive the timely payment of the benefits which he believes are due under the Plan, the Claimant may make a claim for benefits in the manner hereinafter provided.

9.2    Claims. All claims for benefits under the Plan shall be made in writing and shall be signed by the Claimant. Claims shall be submitted to the Administrative Record Keeper (or such other person who is delegated the responsibility by the Committee to review claims). If the Claimant does not furnish sufficient information with the claim for the Administrative Record Keeper to determine the validity of the claim, the Administrative Record Keeper shall indicate to the Claimant any additional information which is necessary for the Administrative Record Keeper to determine the validity of the claim.

9.3    Review of Claims. Each claim hereunder shall be acted on and approved or disapproved by the Administrative Record Keeper within 90 days following the receipt by the Administrative Record Keeper of the information necessary to process the claim. If special circumstances require an extension of the time needed to process the claim, this 90-day period may be extended 180 days after the claim is received. The Claimant shall be notified before the end of the original period if an extension is necessary, the reason for the extension and the date by which it is expected that a decision will be made. In the event the Administrative Record Keeper denies a claim for benefits in whole or in part, the Administrative Record Keeper shall notify the Claimant in writing of the denial of the claim and notify the Claimant of his right to a review of the Administrative Record Keeper’s decision by the Administrative Record Keeper. Such notice by the Administrative Record Keeper shall also set forth, in a manner calculated to be understood by the Claimant, the specific reason for such denial, the specific provisions of the Plan on which the denial is based, and a description of any additional material or information necessary to perfect the claim with an explanation of the Plan’s appeals procedure as set forth in this Section 9.

9.4    Appeals. Any applicant whose claim for benefits is denied in whole or in part may appeal to the Committee for a review of the decision by the Administrative Record Keeper. Such appeal must be made within 60 days after the applicant has received actual or constructive notice of the denial as provided above. An appeal must be submitted in writing within such period and must:

1request a review by the Committee of the claim for benefits under the Plan;

9.5    Review of Appeals. The Committee shall act upon each appeal within 60 days after receipt thereof unless special circumstances require an extension of the time for processing, in which case a decision shall be rendered by the Committee as soon as possible but not later than 120 days after the appeal is received by it. If such an extension of time for processing is required because of special circumstances, written notice of the extension shall be furnished prior to the commencement of the extension describing the reasons an extension is needed and the date when the determination will be made. The Committee may require the Claimant to submit such additional facts, documents or other evidence as the Committee in its discretion deems necessary or advisable in making its review. The Claimant shall be given the opportunity to review pertinent documents or materials upon submission of a written request to the Committee, provided that the Committee finds the requested documents or materials are pertinent to the appeal.

9.6    Final Decisions. On the basis of its review, the Committee shall make an independent determination of the Participant’s eligibility for benefits under the Plan. The decision of the Committee on any appeal of a claim for benefits shall be final and conclusive upon all parties thereto.

9.7    Denial of Appeals. In the event the Committee denies an appeal in whole or in part, it shall give written notice of the decision to the Claimant, which notice shall set forth, in a manner calculated to be understood by the Claimant, the specific reasons for such denial and which shall make specific reference to the pertinent provisions of the Plan on which the Committee’s decision is based.

9.8    Statute of Limitations. A Claimant wishing to seek judicial review of an adverse benefit determination under the Plan, whether in whole or in part, must file any suit or legal action, including, without limitation, a civil action under Section 502(a) of ERISA, within three years of the date the final decision on the adverse benefit determination on review is issued or should have been issued under Section 9.6 or lose any rights to bring such an action. If any such judicial proceeding is undertaken, the evidence presented shall be strictly limited to the evidence timely presented to the Committee. Notwithstanding anything in the Plan to the contrary, a Claimant must exhaust all administrative remedies available to such Claimant under the Plan before such Claimant may seek judicial review pursuant to Section 502(a) of ERISA.

10.1    Amendment or Termination. The Plan may be amended or terminated at any time by the Board of Directors or the Committee; provided, however, that no amendment or termination may reduce the balance of a Participant’s Deferral Account as of the date of the amendment or termination without the Participant’s written consent. Except as otherwise permitted by Section 409A, the termination of the Plan shall not result in any acceleration of the payment of any Deferral Account under the Plan, unless (i) all arrangements sponsored by the Company that would be aggregated with the Plan under Section 409A if the same Participant participated in all such arrangements are terminated, (ii) no payments other than payments that would be delivered under the terms of such arrangements if the termination had not occurred are made within 12 months of the termination of such arrangements, (iii) all payments under the Plan are made within 24 months of the termination of the arrangements and (iv) the Company does not adopt a new arrangement that would be aggregated with the Plan under Section 409A if the same Participant participated in both arrangements, at any time within the five years following the date of Plan termination. Notwithstanding the foregoing, the Committee shall have the discretion to terminate the Plan and distribute the entire balance of each Participant’s Deferral Account in connection with a Change in Control provided that all amounts attributable to such Deferral Accounts are distributed within 12 months of such Change in Control.

10.2    409A Benefit Amendments. Notwithstanding any provision in the Plan to the contrary, the Board of Directors, the Committee or the Deferred Compensation Tax Compliance Committee shall have the independent right prospectively and/or retroactively to amend or modify (i) the Plan, (ii) any Participant elections under the Plan and (iii) the time and manner of any payment of benefits under the Plan in accordance with Section 409A, in each case, without the consent of any Participant, to the extent that the Board of Directors, the Committee or the Deferred Compensation Tax Compliance Committee deems such action to be necessary or advisable (A) to avoid the imposition on any Participant of adverse or unintended tax consequences under Section 409A (“Section 409A Compliance”) or (B) to address regulatory or other changes or developments that affect the terms of the Plan that were included in the Plan prior to such change or development with the intent of effecting Section 409A Compliance. Any determinations made by the Board of Directors, the Committee or the Deferred Compensation Tax Compliance Committee under this Section 10.2 shall be final, conclusive and binding on all persons.

11.1    No Effect on Employment Rights. Nothing contained herein shall be construed as a contract of employment with any person. The Plan and its establishment shall not confer upon any person the right to be retained in the service of the Company or limit the right of the Company to discharge or otherwise deal with any person without regard to the existence of the Plan.

11.2    Funding. The Plan at all times shall be entirely unfunded, and no provision shall at any time be made with respect to segregating any assets of the Company for payment of any benefits hereunder. No Participant, Beneficiary or other person shall have any interest in any particular assets of the Company by reason of a right to receive a benefit under the Plan, and any such Participant, Beneficiary or other person shall have the rights of a general unsecured creditor of the Company with respect to any rights under the Plan. Notwithstanding the foregoing, the Committee or the Board of Directors, in its discretion, may establish a grantor trust to fund benefits payable under the Plan and administrative costs relating to the Plan. The assets of said trust shall be held separate and apart from other Company funds and shall be used exclusively for the purposes set forth in the Plan and the applicable trust agreement, subject to the following conditions:

11.3    Anti-assignment. To the maximum extent permitted by law, no benefit payable under the Plan shall be subject in any manner to anticipation, alienation, sale, transfer, assignment, pledge, encumbrance, or charge, and any attempt to do so shall be void, nor shall any such benefit be in any manner liable for or subject to garnishment, attachment, execution or levy, or liable for or subject to the debts, contracts, liabilities, engagements or torts of the Participant.

11.4    Taxes. The Company shall have the right to deduct any required taxes from each payment to be made under the Plan.

11.5    Construction. The Plan is intended to be an unfunded deferred compensation arrangement for a select group of management or highly compensated employees within the meaning of ERISA and therefore exempt from the requirements of Sections 201, 301 and 401 of ERISA. Whenever the terms of the Plan require the payment of an amount by a specified

date, the Company shall use reasonable efforts to make payment by that date. The Company shall not be (i) liable to the Participant or any other person if such payment is delayed for administrative or other reasons to a date that is later than the date so specified by the Plan or (ii) required to pay interest or any other amount in respect of such delayed payment except to the extent specifically contemplated by the terms of the Plan.

11.6    Incapacity of Participant. In the event a Participant is declared incompetent and a conservator or other person legally charged with the care of his person or his estate is appointed, any benefits under the Plan to which such Participant is entitled shall be paid to such conservator or other person legally charged with the care of his person or estate.

11.7    Severability. In the event that any one or more of the provisions of the Plan shall be or become invalid, illegal or unenforceable in any respect, the validity, legality and enforceability of the remaining provisions of the Plan shall not be affected thereby.

11.8    Governing Law. The Plan is established under and shall be governed and construed in accordance with the laws of the State of New Jersey, to the extent that such laws are not preempted by ERISA.

(a)    Deferral Elections. An Employee of the Company who first becomes eligible to participate in the Plan on or after January 1, 2005 and on or prior to March 15, 2005 shall be permitted to elect, at any time on or prior to March 15, 2005, in accordance with procedures established by the Committee and Q&A 21 of Notice 2005-1, to defer his Base Salary earned in the calendar year beginning on January 1, 2005 and/or Bonus Compensation earned in the calendar year beginning on January 1, 2004 or January 1, 2005; provided, however, that the Base Salary and/or Bonus Compensation to which such election relates has not been paid or become payable at the time of such election.

(2)    With respect to amounts previously deferred in the Deferral Account, a Participant shall be permitted to make, through December 31, 2006, an election to change the time and/or form of payment, to the extent such election is permitted under the terms of the Plan; provided, however, that such election shall apply solely to amounts that would not otherwise be payable in 2006 and shall not cause any amount to be paid in 2006 that would not otherwise be payable in 2006.

(3)    With respect to amounts previously deferred in the Deferral Account, a Participant shall be permitted to make from January 1, 2007 through December 31, 2007, an election to change the time and/or form of payment, to the extent such election is permitted under the terms of the Plan; provided, however, that such election shall apply solely to amounts that would not otherwise be payable in 2007 and shall not cause any amount to be paid in 2007 that would not otherwise be payable in 2007.

(4)    Payment elections pursuant to this Section (b) shall be deemed pursuant to Q&A 19(c) of Notice 2005-1, as amended by the preamble to the proposed Treasury Regulations under Section 409A, issued on September 29, 2005.

(c)    Termination of Participation; Cancellation of Deferral Election.

(1)    Effective as of December 1, 2005, a Participant who elected in 2004 to defer Bonus Compensation earned in 2005 and payable in 2006 shall be permitted to elect by no later than December 31, 2005, in accordance with procedures established by the Administrative Record Keeper, to cancel, in whole or in part, his deferral election under the Plan with respect to his Bonus Compensation earned in 2005 and payable in 2006.

(2)    The Committee shall be permitted, in 2005, to the extent it deems necessary or advisable under Section 409A, to cancel any 2005 deferral election and/or terminate a

Participant’s participation in the Plan solely with respect to his Deferral Account; provided that amounts subject to such cancellation or termination be distributed by the later of December 31, 2005 and the date on which such amounts are earned and vested.

(3)    Any termination of participation or cancellation of a deferral election pursuant to this Section (c) shall be deemed pursuant to Q&A 20(a) of Notice 2005-1.

The Wyeth 2005 (409A) Deferred Compensation Plan (the "Plan") is hereby amended as follows, effective as of the Closing Date (as defined in the Agreement and Plan of Merger, dated as of January 25, 2009, by and among Pfizer, Inc., Wagner Acquisition Corp., and Wyeth):

Section 1.2(n) of the Plan is hereby amended in its entirety to read as follows:

"(n)    "Company Stock" means the Investment Option available under the Plan that is designed to track the performance of the common stock of Pfizer Inc., par value $0.05 per share, and any successor thereof."

Effective on the closing of the merger contemplated by the Agreement and Plan of Merger, dated as of January 25, 2009, among Pfizer Inc (“Company”), Wagner Acquisition Corp., and Wyeth as the same may be amended from time to time (“Merger”), the Company freezes eligibility under the Wyeth DCP so that no employee may become an “Eligible Employee” (as defined in the Wyeth DCP) after the Merger, and only employees who are eligible to participate in the Wyeth DCP on the Merger shall participate in the Wyeth DCP.

The Plans are hereby amended, effective as of January 1, 2011, by deleting the following language “within ninety (90) days after the date of the Participant’s death,” in each of the plan sections listed below, and replacing it with “in the January following the calendar year in which the Participant’s death occurs”:

 

Effective on and after January 1, 2012, it is hereby acknowledged that the Plan is “frozen” and no further deferrals may be made under the Plan.

The Company maintains the Prior Plan, which was designed to provide certain Employees with the opportunity to voluntarily defer receipt of a portion of their compensation. All amounts deferred under the Prior Plan that, for purposes of Section 409A, were both earned and vested on December 31, 2004 shall be subject to the terms of the Prior Plan as in effect on December 31, 2004. The ERP Grandfathered Benefits, SERP Grandfathered Benefits and the SESP Grandfathered Account that are rolled over in a Valid Notional Rollover shall be rolled over into the Prior Plan and be subject to the terms of the Prior Plan as in effect on December 31, 2004. Notwithstanding the foregoing, with respect to any Participant employed by Zoetis Inc., on and following the date Zoetis Inc. is no longer a wholly owned subsidiary of the Company due to a tax-free distribution to the Company’s stockholders of all or a portion of its equity interest in Zoetis, such Participant shall be deemed to have incurred a termination of employment only upon his or her “Separation from Service” within the meaning of Section 409A of the Internal Revenue Code of 1986, as amended, for purposes of the distribution of his or her Grandfathered Benefits.
