1999 Stock Incentive Plan, as amended through November 16, 2006

 Exhibit 10.16 
 Wyeth 
 1999 STOCK INCENTIVE PLAN 
 (As approved by stockholders on April 22, 1999 and as amended by the Board of Directors through November 16, 2006) 
 Section 1. Purpose. The purpose of the 1999 Stock Incentive Plan (the “Plan”) is to provide favorable opportunities for officers
and other key employees of Wyeth (the “Company”) and its subsidiaries to acquire shares of Common Stock of the Company or to benefit from the appreciation thereof. Such opportunities should provide an increased incentive for these
employees to contribute to the future success and prosperity of the Company, thus enhancing the value of the stock for the benefit of the stockholders, and increase the ability of the Company to attract and retain individuals of exceptional skill
upon whom, in large measure, its sustained progress, growth and profitability depend. 
 Pursuant to the Plan, options to purchase the
Company’s Common Stock (“Options”) and Stock Appreciation Rights may be granted and Restricted Stock may be awarded by the Company. Options granted under the Plan may be either incentive stock options, as defined in
Section 422(b) of the Internal Revenue Code of 1986, as amended (the “Code”), or options which do not meet the requirements of said Section 422(b) of the Code, herein referred to as non-qualified stock options. 
 It is intended, except as otherwise provided herein, that incentive stock options may be granted under the Plan and that such incentive stock options
shall conform to the requirements of Section 422 and 424 of the Code and to the provisions of this Plan and shall otherwise be as determined by the Committee (as hereinafter defined) and, to the extent provided in the last sentence of
Section 2 hereof, approved by the Board of Directors. The terms “subsidiaries” and “subsidiary corporation” shall have the meanings given to them by Section 424 of the Code. All section references to the Code in this
Plan are intended to include any amendments or substitutions therefor subsequent to the adoption of the Plan. 
 Section 2.
Administration. The Plan shall be administered by a Compensation and Benefits Committee (the “Committee”) consisting of two or more members of the Board of Directors of the Company, each of whom shall be (i) a “non-employee
director” within the meaning of Rule 16b-3 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and (ii) an “outside director” within the meaning of Section 162(m) of the Code. The Committee
shall have full authority to grant Options and Stock Appreciation Rights, and make Restricted Stock awards, to interpret the Plan and to make such rules and regulations and establish such procedures as it deems appropriate for the administration of
the Plan, taking into consideration the recommendations of management. The decisions of the Committee shall be binding and conclusive for all purposes and upon all persons unless and except to the extent that the Board of Directors of the Company
shall have previously directed that all or specified types of decisions of the Committee shall be subject to approval by the Board of Directors. Notwithstanding the foregoing and anything else in the Plan to the contrary, the Committee, in its sole
discretion, may delegate the Committee’s authority and duties under the Plan to the Chairman of the Board of Directors and Chief Executive Officer of the Company, as a Board of Directors committee of one under Delaware law, or to any other
committee of the Board of Directors, under such conditions and limitations as the Board of Directors or the Committee may from time to time establish, except that only the Committee may make any determinations regarding awards to participants who
are subject to Section 16 of the Exchange Act. 
 Section 3. Number of Shares. The total number of shares which may be sold
or awarded under the Plan and with respect to which Stock Appreciation Rights may be exercised shall not exceed 65,000,000 shares of the Company’s Common Stock. The total number of shares which may be sold or awarded under the Plan to any
optionee (hereinafter defined), including shares for which Stock Appreciation Rights may be exercised, shall not exceed 10% of such number, as and if adjusted, over the life of the Plan. The shares may be authorized and unissued or issued and
reacquired shares, as the Board of Directors from time to time may determine. Shares with respect to which Options or Stock Appreciation Rights are not exercised prior to termination of the Option and shares that 

 
are part of a Restricted Stock award which are forfeited before the restrictions lapse shall be available for Options and Stock Appreciation Rights
thereafter granted and for Restricted Stock thereafter awarded under the Plan, to the fullest extent permitted by Rule 16b-3 under the Exchange Act (if applicable at the time). 
 Section 4. Participation. The Committee may, from time to time, select and grant Options and Stock Appreciation Rights to officers (whether
or not directors) and other key employees of the Company and its subsidiaries (“optionees”) and award Restricted Stock to officers (whether or not directors) and other key employees of the Company and its subsidiaries and shall determine
the number of shares subject to each Option or award. 
 Section 5. Terms and Conditions of Options. The terms and conditions of
each Option and each Stock Appreciation Right shall be set forth in an agreement or agreements between the Company and the optionee. Such terms and conditions shall include the following as well as such other provisions, not inconsistent with the
Plan, as may be deemed advisable by the Committee: 
 (a) Number of Shares. The number of shares subject to the Option. 
 (b) Option Price. The option price per share (the “Option Price”), shall not be less than 100% of the Fair Market Value of a share of
the Company’s Common Stock on the date the Option is granted. Fair Market Value of the Common Stock as of any date, shall be deemed to be the closing price of the Common Stock on the Consolidated Transaction Reporting System on such date or if
such date is not a trading day, on the most recent trading day prior to such date. Once granted, except as provided in Section 8, the Option Price of outstanding Options may not be reduced, whether by repricing exchange or otherwise.

 (c) Date of Grant. Subject to previous directions of the Board of Directors pursuant to the last sentence of Section 2, the
date of grant of an Option shall be the date when the Committee meets and awards such Option. 
 (d) Payment. The Option Price
multiplied by the number of shares to be purchased by exercise of the Option shall be paid upon the exercise thereof. Unless the terms of an Option provide to the contrary, upon exercise, the aggregate Option Price shall be payable by delivering to
the Company (i) cash equal to such aggregate Option Price, (ii) shares of the Company’s Common Stock owned by the grantee having a fair market value on the day the Company’s Common Stock is quoted on the Consolidated Transaction
Reporting System immediately preceding the date of exercise (determined in accordance with Section 5(b) or as otherwise permitted by the Committee) at least equal to such aggregate Option Price, (iii) a combination of any of the above
methods which total to such aggregate Option Price, or (iv) any other form of consideration which has been approved by the Committee, including under any approved cashless exercise mechanism; and payment of such aggregate Option Price by any
such means shall be made and received by the Company prior to the delivery of the shares as to which the Option was exercised. The right to deliver in full or partial payment of such Option Price any consideration other than cash shall be limited to
such frequency as the Committee shall determine in its absolute discretion. A holder of an Option shall have none of the rights of a stockholder until the shares are issued to him or her; provided that if an optionee exercises an Option and the
appropriate purchase price is received by the Company in accordance with this Section 5(d) prior to any dividend record date, such optionee shall be entitled to receive the dividends which would be paid on the shares subject to such exercise if
such shares were outstanding on such record date. 
 (e) Term of Options. Each Option granted pursuant to the Plan shall be for the
term specified in the applicable option agreement (the “Option Agreement”) subject to earlier termination in all cases as provided in paragraph (g) of this Section. 
  

 2 

 (f) Exercise of Option. Options granted under the Plan may be exercised during the period and in
accordance with the conditions set forth in the Plan and the applicable Option Agreement; provided, however, that (i) no option granted under the Plan may be exercisable earlier than the later of (A) one year from the date of grant or
(B) the date on which the optionee completes two years of continuous employment with the Company or one or more of its subsidiaries, and (ii) in the event of an optionee’s death, Retirement (as defined below) or Disability (as defined
below), any options held by such optionee shall become exercisable on his or her Retirement date, the date his or her employment terminates on account of Disability or the date of his or her death provided he or she has been in the continuous
employment of the Company or one or more of its subsidiaries for at least two years at such time. No Option may be exercised after it is terminated as provided in paragraph (g) of this Section, and no Option may be exercised unless the optionee
is then employed by the Company or any of its subsidiaries and shall have been continuously employed by the Company or one or more of such subsidiaries since the date of the grant of his or her Option, except (x) as provided in paragraph
(g) of this Section, and (y) in the case of the optionee’s Retirement or Disability (in which case the optionee may exercise the Option to the extent he or she was entitled to exercise it at the time of such termination or such
shorter period as may be provided in the Option Agreement) or death (in which case the Option may be exercised by the optionee’s legal representative or legatee or such other person designated by an appropriate court as the person entitled to
exercise such Option to the extent the optionee was entitled to exercise it at the time of his or her death). As used herein, “Retirement” shall mean termination of the optionee’s full-time employment on or after the earliest
retirement age under any qualified retirement plan of the Company or its subsidiaries which covers the optionee, or age 55 with 5 continuous years of such employment if there is no such plan and “Disability” shall mean termination of the
optionee’s full-time employment for reason of disability for purposes of at least one qualified retirement plan or long term disability plan maintained by the Company or its subsidiaries in which the optionee participates. Non-qualified stock
options and incentive stock options may be exercised regardless of whether or not other Options granted to the optionee pursuant to the Plan are outstanding or whether or not other stock options granted to the optionee pursuant to any other plan are
outstanding. 
 (g) Termination of Options. An Option, to the extent not validly exercised, shall terminate upon the occurrence of the
first of the following events: 
 (i) On the date specified in the Option Agreement; 
 (ii) Three months after termination by the Company or one of its subsidiaries of the optionee’s employment for any reason other than
in the case of death, Retirement, Disability or deliberate gross misconduct, determined in the sole discretion of the Committee, during which three month period the Option may be exercised by the optionee to the extent the optionee was entitled to
exercise it at the time of such termination; 
 (iii) Concurrently with the time of termination by the Company or one of its
subsidiaries of the optionee’s employment for deliberate gross misconduct, determined in the sole discretion of the Committee (for purposes only of this subparagraph (iii) an Option shall be deemed to be exercised when the optionee has
received the stock certificate representing the shares for which the Option was exercised); or 
 (iv) Concurrently with the
time of termination by the employee of his or her employment with the Company or one of its subsidiaries for reasons other than Retirement, Disability or death. 
 Notwithstanding the above, no Option shall be exercisable after termination of employment unless the optionee shall have, during the
entire time period in which his or her Options are exercisable, (a) refrained from becoming or serving as an officer, director, partner or employee of any individual proprietorship, partnership or corporation, or the owner of a business, or a
member of a partnership which 

  

 3 

 
conducts a business in competition with the Company or renders a service (including without limitation, advertising agencies and business consultants) to
competitors with any portion of the business of the Company, (b) made himself or herself available, if so requested by the Company, at reasonable times and upon a reasonable basis to consult with, supply information to, and otherwise cooperate
with, the Company and (c) refrained from engaging in deliberate action which, as determined by the Committee, causes substantial harm to the interests of the Company or, if occurring before termination of employment, would have otherwise
constituted deliberate gross misconduct for purposes of Section 5(g)(iii). If these conditions are not fulfilled, the optionee shall forfeit all rights to any unexercised Option as of the date of the breach of the condition. 
 (h) Non-transferability of Options and Stock Appreciation Rights. Options and Stock Appreciation Rights shall not be transferable by the optionee
other than by will or the laws of descent and distribution, and Options and Stock Appreciation Rights shall during his or her lifetime be exercisable only by the optionee; provided, however, that the Committee may, in its sole
discretion, allow for transfer of Options (other than incentive stock options, unless such transferability would not adversely affect incentive stock option tax treatment) to other persons or entities, subject to such conditions or limitations as it
may establish to ensure that transactions with respect to Options intended to be exempt from Section 16(b) of the Exchange Act pursuant to Rule 16b-3 under the Exchange Act do not fail to maintain such exemption as a result of the Committee
causing Options to be transferrable, or for other purposes; provided further, however, that for any Option that is transferred, other than by the laws of descent and distribution, any related Stock Appreciation Right shall be
extinguished. 
 (i) Applicable Laws or Regulations. The Company’s obligation to sell and deliver stock under the Option is
subject to such compliance as the Company deems necessary or advisable with federal and state laws, rules and regulations. 
 (j)
Limitations on Incentive Stock Options. To the extent that the aggregate fair market value of the Company’s Common Stock, determined at the time of grant in accordance with the provisions of Section 5(b), with respect to which
incentive stock options granted under this or any other Plan of the Company are exercisable for the first time by an optionee during any calendar year exceeds $100,000, or such other amount as may be permitted under the Code, such excess shall be
considered non-qualified stock options. 
 Notwithstanding anything in the Plan to the contrary, any incentive stock option granted to any
individual who, at the time of grant, is the owner, directly or indirectly, of stock possessing more than ten percent (10%) of the total combined voting power of all classes of stock of the Company or any subsidiary thereof, shall (i) have
a term not exceeding five years from the date of grant and (ii) shall have an option price per share of not less than 110% of the fair market value of the Company’s Common Stock on the date the incentive stock option is granted (determined
in accordance with the last sentence of Section 5(b)). 
 Section 6. Stock Appreciation Rights. 
 (a) The Committee may, in its sole discretion, from time to time grant Stock Appreciation Rights to certain optionees in connection with any Option
granted under this Plan and in connection with Options granted under the 1990, 1993 and 1996 Stock Incentive Plans and under the 1985 Stock Option Plan. Stock Appreciation Rights may be granted either at the time of the grant of an Option under the
Plan or at any time thereafter during the term of the Option, provided such Stock Appreciation Rights may also be granted with respect to outstanding Options under the 1990, 1993 and 1996 Stock Incentive Plans and the 1985 Stock Option Plan. Stock
Appreciation Rights may be granted with respect to all or part of the stock under a particular Option. 
 (b) Stock Appreciation Rights shall
entitle the holder of the related Option, upon exercise, in whole or in part, of the Stock Appreciation Rights, to receive payment in the amount and form determined pursuant to 

  

 4 

 
subparagraph (iii) of paragraph (c) of this Section 6. Stock Appreciation Rights may be exercised only to the extent that the related Option
has not been exercised. The exercise of Stock Appreciation Rights shall result in a pro rata surrender of the related Option to the extent that the Stock Appreciation Rights have been exercised. 
 (c) Stock Appreciation Rights shall be subject to such terms and conditions which are not inconsistent with the Plan as shall from time to time be
approved by the Committee and reflected in the applicable Option Agreement (or in a separate document, which shall be considered for purposes of the Plan to be incorporated into and part of the applicable Option Agreement), and to the following
terms and conditions. 
 (i) Stock Appreciation Rights shall be exercisable at such time or times and to the extent, but only
to the extent, that the Option to which they relate shall be exercisable. 
 (ii) [Reserved] 
 (iii) Upon exercise of Stock Appreciation Rights, the holder thereof shall be entitled to elect to receive therefor payment in the form of
shares of the Company’s Common Stock (rounded down to the next whole number so no fractional shares are issued), cash or any combination thereof in an amount equal in value to the difference between the Option Price per share and the fair
market value per share of Common Stock on the date of exercise multiplied by the number of shares in respect of which the Stock Appreciation Rights shall have been exercised, subject to any limitation on such amount which the Committee may in its
discretion impose. The fair market value of Common Stock shall be deemed to be the mean between the highest and lowest sale prices of the Common Stock on the Consolidated Transaction Reporting System on the date the Stock Appreciation Right is
exercised or if no transaction on the Consolidated Transaction Reporting System occurred on such date, then on the last preceding day on which a transaction did take place. 
 (iv) Any exercise of Stock Appreciation Rights by an officer or director subject to Section 16(b) of the Exchange Act, as well as any
election by such officer or director as to the form of payment of Stock Appreciation Rights (Common Stock, cash or any combination thereof), shall be made during the ten-day period beginning on the third business day following the release for
publication of any quarterly or annual statement of sales and earnings by the Company and ending on the twelfth business day following the date of such release (“window period”). In the event that such a director or officer exercises a
Stock Appreciation Right for cash or stock pursuant to this Section 6 during a “window period”, the day on which such right is effectively exercised shall be that day, if any, during such “window period” which is designated
by the Committee in its discretion for all such exercises by such individuals during such period. If no such day is designated, the day of effective exercise shall be determined in accordance with normal administrative practices of the Plan.

 (d) To the extent that Stock Appreciation Rights shall be exercised, the Option in connection with which such Stock Appreciation Rights
shall have been granted shall be deemed to have been exercised for the purpose of the maximum limitations set forth in the Plan under which such Options shall have been granted. Any shares of Common Stock which are not purchased due to the surrender
in whole or in part of an Option pursuant to this Section 6 shall not be available for granting further Options under the Plan. 
 Section 6A. Deferral. 
 (a) Notwithstanding anything herein to the contrary, an optionee may elect, at the discretion
of, and in accordance with rules which may be established by, the Committee, to defer delivery of the proceeds of exercise of an unexercised Option or the corresponding Stock Appreciation Right, provided such election is irrevocable and is made
(i) at least six months prior to the date that such Option or the corresponding Stock Appreciation Right 

  

 5 

 
otherwise would expire and (ii) at least one month prior to the date such Option or the corresponding Stock Appreciation Right is exercised (or such
shorter period as may be determined by the Committee). Upon such exercise, the amount deferred shall be equal in value to the difference between the Option Price per share and the fair market value per share of the Common Stock on the date of
exercise (determined in accordance with Section 5(b)), multiplied by the number of shares covered by such exercise and in respect of which the optionee shall have made the deferral election, and shall be credited to an account in the name of
the optionee on the books and records of the Company (a “Deferred Compensation Account”) at the date of exercise. A separate Deferred Compensation Account shall be maintained with respect to each Option or corresponding Stock Appreciation
Right subject to an effective deferral election. 
 (b) Interest shall be credited on amounts in the Deferred Compensation Account from the
date of exercise of the Option or the corresponding Stock Appreciation Right to the date of payment, at the rate of interest determined by the Committee and communicated to the optionees. The value of an optionee’s Deferred Compensation Account
shall be payable in a lump sum cash payment or in annual installments over a period not to exceed 10 years or as otherwise determined by the Committee. At the time an optionee makes such deferral election, the optionee shall elect the form of
payment and date for lump sum payment or commencement of annual payments of the Deferred Compensation Account, with such date at least one year subsequent to the date of exercise of the Option or corresponding Stock Appreciation Right, but not later
than the date of the optionee’s termination of employment with Company. Notwithstanding any election by an optionee, in the event of Disability or death of the optionee, the optionee’s Deferred Compensation Account shall be paid within 90
days in the form of a single lump sum. 
 (c) Notwithstanding the deferred payment date elected by the optionee, the Committee may, in its
discretion, allow for early payment of an optionee’s Deferred Compensation Account in the event of an “unforeseeable emergency.” For this purpose, an unforeseeable emergency shall be defined as an unanticipated emergency that is
caused by an event beyond the control of the optionee and that would result in severe financial hardship to the optionee if early withdrawal were not permitted. Any withdrawal on account of an unforeseeable emergency must be limited to the amount
necessary to meet the emergency. The above provisions regarding a withdrawal upon an unforeseeable emergency shall be interpreted in accordance with published revenue procedures, regulations, releases or interpretations. In addition, Deferred
Compensation Accounts may be distributed on an accelerated basis in the discretion of the Committee. 
 (d) Optionees have the status of
general unsecured creditors of the Company with respect to their Deferred Compensation Accounts, and such accounts constitute a mere promise by the Company to make payments with respect thereto. 
 (e) An optionee’s right to benefit payments under the Plan with respect to the Deferred Compensation Accounts may not be anticipated, alienated,
sold, transferred, assigned, pledged, encumbered, attached or garnished by creditors of the optionee or the optionee’s beneficiary and any attempt to do so shall be void. 
 (f) Notwithstanding anything in the Plan to the contrary or any Option Agreement to the contrary, effective as of January 1, 2005, no optionee shall
be permitted to elect to defer delivery of the proceeds of exercise of an unexercised Option or the corresponding Stock Appreciation Right. 
 Section 7. Restricted Stock Performance Awards. The Committee may, in its sole discretion, from time to time, make awards of shares of the Company’s Common Stock or awards of units representing shares of the Company’s
Common Stock, up to 8,000,000 shares in the aggregate, to such officers and other key employees of the Company and its subsidiaries in such quantity, and on such terms, conditions and restrictions (whether based on performance standards, periods of
service or otherwise) as the Committee shall establish (“Restricted Stock”). The terms, conditions and restrictions of any Restricted Stock award made under this Plan shall be set forth in an agreement or agreements between the Company and
the recipient of the award. 
  

 6 

 (a) Issuance of Restricted Stock. The Committee shall determine the manner in which Restricted
Stock shall be held during the period it is subject to restrictions. 
 (b) Stockholder Rights. Beginning on the date of grant of the
Restricted Stock award and subject to the execution of the award agreement by the recipient of the award and subject to the terms, conditions and restrictions of the award agreement, the Committee shall determine to what extent the recipient of the
award has the rights of a stockholder of the Company including, but not limited to, whether or not the employee receiving the award has the right to vote the shares or to receive dividends or dividend equivalents. 
 (c) Restriction on Transferability. None of the shares or units of a Restricted Stock award may be assigned or transferred, pledged or sold prior
to their delivery to a recipient or, in the case of a recipient’s death, to the recipient’s legal representative or legatee or such other person designated by an appropriate court; provided, however, that the Committee may, in its sole
discretion, allow for transfer of shares or units of a Restricted Stock Award to other persons or entities. 
 (d) Delivery of Shares.
Upon the satisfaction of the terms, conditions and restrictions contained in the Restricted Stock award agreement or the release from the terms, conditions and restrictions of a Restricted Stock award agreement, as determined by the Committee, the
Company shall deliver, as soon as practicable, to the recipient of the award (or permitted transferee), or in the case of his or her death to his or her legal representative or legatee or such other person designated by an appropriate court, a stock
certificate for the appropriate number of shares of the Company’s Common Stock, free of all such restrictions, except for any restrictions that may be imposed by law. 
 (e) Forfeiture of Restricted Stock. Subject to Section 7(f), all of the restricted shares or units with respect to a Restricted Stock award
shall be forfeited and all rights of the recipient with respect to such restricted shares or units shall terminate unless the recipient continues to be employed by the Company or its subsidiaries until the expiration of the forfeiture period and the
satisfaction of any other conditions set forth in the award agreement. 
 (f) Waiver of Forfeiture Period. Notwithstanding any other
provisions of the Plan, the Committee may, in its sole discretion, waive the forfeiture period and any other conditions set forth in any award agreement under certain circumstances (including the death, Disability or Retirement of the recipient of
the award or a material change in circumstances arising after the date of an award) and subject to such terms and conditions (including forfeiture of a proportionate number of the restricted shares) as the Committee shall deem appropriate.

 Section 8. Adjustment in Event of Change in Stock. Subject to Section 9, in the event of stock split, stock dividend,
cash dividend (other than a regular cash dividend), combination of shares, merger, or other relevant change in the Company’s capitalization, the Committee shall, subject to the approval of the Board of Directors, appropriately adjust the number
and kind of shares available for issuance under the Plan, the number, kind and Option Price of shares subject to outstanding Options and Stock Appreciation Rights and the number and kind of shares subject to outstanding Restricted Stock awards;
provided, however, that to the extent permitted in the case of incentive stock options by Sections 422 and 424 of the Code, in the event that the outstanding shares of Common Stock of the Company are increased or decreased or changed into or
exchanged for a different number or kind of shares or other securities of the Company or of another corporation, through reorganization, merger, consolidation, liquidation, recapitalization, reclassification, stock split-up, combination of shares or
dividend, appropriate adjustment in the number and kind of shares as to which Options may be granted and as to which Options or portions thereof then unexercised shall be exercisable, and in the Option Price thereof, shall be made to 

  

 7 

 
the end that the proportionate number of shares or other securities as to which Options may be granted and the optionee’s proportionate interests under
outstanding Options shall be maintained as before the occurrence of such event; provided, that any such adjustment in shares subject to outstanding Options (including any adjustments in the Option Price) shall be made in such manner as not to
constitute a modification as defined by subsection (h)(3) of Section 424 of the Code; and provided, further, that, in the event of an adjustment in the number or kind of shares under a Restricted Stock award pursuant to this Section 8, any
new shares or units issued to a recipient of a Restricted Stock award shall be subject to the same terms, conditions and restrictions as the underlying Restricted Stock award for which the adjustment was made. 
 Section 9. Effect of a Change of Control. 
 (a) For purposes of this Section 9, “Change in Control” shall, unless the Board of Directors of the Company otherwise directs by resolution adopted prior thereto or, in the case of a particular award,
the applicable award agreement states otherwise, be deemed to occur if (i) any “person” (as that term is used in Sections 13 and 14(d)(2) of the Exchange Act) other than a Permitted Holder (as defined below) is or becomes the
beneficial owner (as that term is used in Section 13(d) of the Exchange Act), directly or indirectly, of 50% or more of either the outstanding shares of Common Stock or the combined voting power of the Company’s then outstanding voting
securities entitled to vote generally, (ii) during any period of two consecutive years, individuals who constitute the Board of Directors of the Company at the beginning of such period cease for any reason to constitute at least a majority
thereof, unless the election or the nomination for election by the Company’s stockholders of each new director was approved by a vote of at least three-quarters of the directors then still in office who were directors at the beginning of the
period or (iii) the Company undergoes a liquidation or dissolution or a sale of all or substantially all of the assets of the Company. No merger, consolidation or corporate reorganization in which the owners of the combined voting power of the
Company’s then outstanding voting securities entitled to vote generally prior to said combination, own 50% or more of the resulting entity’s outstanding voting securities shall, by itself, be considered a Change in Control. As used herein,
“Permitted Holder” means (i) the Company, (ii) any corporation, partnership, trust or other entity controlled by the Company and (iii) any employee benefit plan (or related trust) sponsored or maintained by the Company or
any such controlled entity. 
 (b) Except to the extent reflected in a particular award agreement, in the event of a Change of Control:

 (i) notwithstanding any vesting schedule, or any other limitation on exercise or vesting, with respect to an award of
Options, Stock Appreciation Rights or Restricted Stock, such Options or Stock Appreciation Rights shall become immediately exercisable with respect to 100 percent of the shares subject thereto, and the restrictions shall expire immediately with
respect to 100 percent of such Restricted Stock award; and 
 (ii) the Committee may, in its discretion and upon at least 10
days advance notice to the affected persons, cancel any outstanding Options, Stock Appreciation Rights or Restricted Stock awards and pay to the holders thereof, in cash, the value of such awards based upon the highest price per share of Company
Common Stock received or to be received by other stockholders of the Company in connection with the Change of Control. 
 Section 10.
Amendment and Discontinuance. The Board of Directors of the Company may from time to time amend or revise the terms of the Plan, or may discontinue the Plan at any time as permitted by law, provided, however, that such amendment shall not
(except as provided in Section 8), without further approval of the stockholders, (i) increase the aggregate number of shares with respect to which awards may be made under the Plan; (ii) change the manner of determining the Option
Price (other than determining the fair market value of the Common Stock to conform with applicable provisions of the Code or regulations and interpretations thereunder); (iii) extend the term of the Plan or the maximum period during which any
Option may be exercised or (iv) make 

  

 8 

 
any other change which, in the absence of stockholder approval, would cause awards granted under the Plan which are then outstanding, or which may be granted
in the future, to fail to meet the exemptions provided by Section 162(m) of the Code. No amendments, revision or discontinuance of the Plan shall, without the consent of an optionee or a recipient of a Restricted Stock award, in any manner
adversely affect his or her rights under any Option theretofore granted under the Plan. No amendments, revision or discontinuance of the Plan shall, without the consent of a Participant, in any manner adversely affect his or her rights under any
Awards theretofore granted under the Plan. Notwithstanding any provision in the Plan to the contrary, the Committee shall have the right to unilaterally amend, revise or discontinue the Plan, and any provision of the Plan and the Committee shall
have the right to unilaterally amend, revise or discontinue any Option Agreement or award agreement, any provision of an Option Agreement or award agreement and any Participant elections under an Option Agreement or award agreement, in each case,
without the consent of any Participant, where such amendment, revision or discontinuance is necessary or desirable to comply with applicable law or to ensure that, with respect to any Option, Restricted Stock award, Stock Appreciation Right or the
cash or shares of common stock into which they are converted, the Participant is not subject to adverse or unintended tax consequences under Section 409A of the Code; provided, however, that, with respect to any Option or Stock Appreciation
Right, nothing in the Plan shall require any amendment or revision to the definition of Change in Control. The discontinuance of the Plan shall not result in the acceleration of issuance of shares of Wyeth common stock, to the extent that such
shares constitute a deferral of compensation for purposes of Section 409A of the Code, 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 payable 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 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. All determinations and actions made by the Board of Directors or the Committee pursuant to this Section shall be final, conclusive and binding on all
persons. 
 Section 11. Effective Date and Duration. The Plan was adopted by the Board of Directors of the Company on
January 28, 1999, subject to approval by the stockholders of the Company at a meeting to be held in April 1999. Neither the Plan nor any Option or Stock Appreciation Right or Restricted Stock award shall become binding until the Plan is
approved by a vote of the stockholders in a manner which complies with Sections 162(m) and 422(b)(1) of the Code. No Option may be granted and no stock may be awarded under the Plan before January 28, 1999 nor after January 27, 2009.

 Section 12. Tax Withholding. Notwithstanding any other provision of the Plan, the Company or its subsidiaries, as appropriate,
shall have the right to deduct from all awards under the Plan cash and/or stock, valued at fair market value on the date of payment in accordance with Section 5(b), in an amount necessary to satisfy all federal, state or local taxes as required
by law to be withheld with respect to such awards. In the case of awards paid in the Company’s Common Stock, the optionee or permitted transferee may be required to pay to the Company or a subsidiary thereof, as appropriate, the amount of any
such taxes which the Company or subsidiary is required to withhold, if any, with respect to such stock. Subject in particular cases to the disapproval of the Committee, the Company may accept shares of the Company’s Common Stock of equivalent
fair market value in payment of such withholding tax obligations if the optionee elects to make payment in such manner. 
 Section 13. Construction and Conditions. The Plan and Options, Restricted Stock awards, and Stock Appreciation Rights granted thereunder shall be governed by and construed in accordance with the laws of the State of Delaware and
in accordance with such federal law as may be applicable. 
  

 9 

 Neither the existence of the Plan nor the grant of any Options or Stock Appreciation Rights or awards of
Restricted Stock pursuant to the Plan shall create in any optionee the right to continue to be employed by the Company or its subsidiaries. Employment shall be “at will” and shall be terminable “at will” by the Company or
employee with or without cause. Any oral statements or promises to the contrary are not binding upon the Company or the employee. 
 Section 14. Section 409A. To the extent that any payments or benefits provided hereunder are considered deferred compensation subject to Section 409A, the Company intends for the Plan to comply with the standards for
nonqualified deferred compensation established by Section 409A (the “409A Standards”). To the extent that any terms of the Plan would subject Participants to gross income inclusion, interest or an additional tax pursuant to
Section 409A, those terms are to that extent superseded by the 409A Standards.

 Exhibit 10.24 
 WYETH 
 RESTRICTED STOCK UNIT AWARD AGREEMENT 
 UNDER THE WYETH 1996 STOCK INCENTIVE PLAN 
 DATE OF GRANT: November 17, 2004 
 NUMBER OF SHARES SUBJECT 
 TO AWARD: 30,000 
 Robert Ruffolo,
Jr., Ph.D. 
 [Address] 
 The Company hereby
awards you restricted stock units (the “Units”) representing shares of Common Stock in the amount set forth above. The Units are subject to the terms and restrictions set forth in the Plan and this Agreement. Each Unit corresponds
to one share of Common Stock. The Units shall be converted into shares of Common Stock on the terms and conditions set forth herein. Capitalized words not otherwise defined in the text of this Agreement or in Paragraph 10 shall have the same
meanings as in the Plan. 
 By signing this Agreement (or otherwise acknowledging, as instructed, your agreement thereto), you acknowledge
and agree that: 
  

	 	•	 	 You have received a copy of the Plan. 

  

	 	•	 	 You have read and understood the terms of the Plan and this Agreement, including the requirement that you defer receipt of the shares of Common Stock until after
your Separation from Service. 

  

	 	•	 	 The Company has the right, without your prior consent, to amend or modify the terms of the Plan or this Agreement to the extent that the Committee deems it
necessary to avoid adverse or unintended tax consequences to you under Section 409A. Such amendments or modifications may limit or eliminate certain rights otherwise available to you under the Plan and/or this Agreement.

 1. No Stockholder Rights Until Issuance of Shares. No shares of Common Stock represented by the Units will be
earmarked for you or your account, and you will not have any of the rights of a stockholder with respect to such shares until such time as the shares are issued to you in accordance with the terms of this Agreement. 
 2. No Transfer of Units. You may not sell, transfer, assign, pledge or otherwise encumber or dispose of the Units granted hereunder. 

3. Conversion to Common Stock; Contribution to Restricted Stock Trust. Unless the Units have been forfeited prior to the Conversion Date in
accordance with the terms of this Agreement, as of the Conversion Date, the following shall apply: (i) the number of Units that would have been earned as of the Conversion Date shall be cancelled; (ii) in exchange for such cancelled

 Units, you will have a future right to receive a number of shares of Common Stock equal to the number of Units so cancelled, subject to Paragraph 5(b); and
(iii) as of the 

 
Conversion Date, the Company shall contribute, subject to Paragraph 5(b), a number of shares of Common Stock equal to the number of Units cancelled to the
Restricted Stock Trust, which shares shall be used to satisfy the Company’s payment obligations to you under your Payment Election and this Agreement, and such shares shall be issued to you as of the Payment Date(s) specified in your Payment
Election or Re-Deferral Election, as the case may be, subject to Paragraph 6, 7 or 8. 
 4. Payment Elections and Re-deferral
Elections. 
 (a) Payment Elections. You are eligible to make a Payment Election to receive the shares of Common Stock issuable to
you under the terms of this Agreement in installments rather than in a lump sum (if your Separation from Service is by reason of your Retirement or Disability) or to delay the date of payment in accordance with the attached ANNEX A. To make
such a Payment Election, you must complete an election form approved by the Committee that conforms to the terms of ANNEX A and return or otherwise submit such form to the Record Keeper as soon as possible after the date hereof, but in no
event later than December 23, 2005. All Payment Elections must comply with the applicable procedures established by the Committee from time to time. 
 (b) Re-Deferral Elections. You may, in accordance with procedures established from time to time by the Committee, also make a Re-Deferral Election with respect to all of the shares of Common Stock earned or
eligible to be earned by you under this Agreement following your Separation from Service by reason of Retirement or Disability. Any such Re-Deferral Election (i) must be in accordance with the provisions of Section 409A (as reasonably
interpreted by the Committee), (ii) must be made in writing and received by the Record Keeper at least one year prior to the Payment Date previously specified in your Payment Election or established under the terms of this Agreement, and
(iii) must delay receipt of payment of the amounts otherwise due to you under this Agreement for the minimum re-deferral period required by Section 409A (for example, in the case of the Payment Date for a lump sum, the minimum re-deferral
period would be for at least five years following such Payment Date). Notwithstanding anything in this Agreement to the contrary, (A) you will be permitted to make a Re-Deferral Election solely to the extent that such election will not result
in adverse or unintended tax consequences to you under Section 409A and (B) issuance of amounts subject to an applicable Re-Deferral Election shall not occur prior to the Payment Date(s) set forth in your Re-Deferral Election solely to the
extent necessary to avoid adverse or unintended tax consequences to you under Section 409A. 
 5. Issuance and Delivery of Shares of
Common Stock; Withholding. 
 (a) Method of Issuance; Time of Delivery; Stockholder Rights. As soon as practicable after a Payment
Date, all shares of Common Stock, if any, earned by you under this Agreement that are to be issued to you as of such Payment Date shall be delivered either through book-entry form as a credit to an account maintained in your name or through the
issuance of a stock certificate representing such shares of Common Stock free of any restrictive legend, other than as may be required by applicable securities laws. Upon such issuance, you shall be the record owner of such shares and shall be
entitled to all of the rights of a stockholder of the Company, including the right to vote and the right to receive dividends. 
 (b)
Amounts to Be Withheld. The number of shares of Common Stock that shall be issued to you as of a Payment Date(s) shall be (i) the number of such shares that would have been issued as of the Payment Date in the absence of this Paragraph
5(b) minus (ii) the number 

  

 - 2 - 

 
of whole shares of Common Stock necessary to satisfy (A) the minimum federal, state and local income tax withholding obligations that are imposed on the
Company by applicable law in respect of the issuance of such award, (B) other tax withholding obligations (e.g., Social Security and Medicare) that may be due from time to time under applicable law (and that may be satisfied by the reduction
effected hereby in the number of issuable shares) and (C) any administrative fees that may be imposed by the Company, in each case, it being understood that the value of the shares referred to in clause (ii) above shall be determined, for
the purposes of satisfying the obligations set forth in this Paragraph 5(b) and determining your income related to such award, on the basis of the average of the high and low per-share prices for the Common Stock as reported on the Consolidated
Transaction Reporting System on the trading day immediately preceding the designated date of issuance or as otherwise determined in Paragraph 8, or on such other reasonable basis for determining fair market value as the Committee may from time to
time adopt. Shares of Common Stock may also be issued and withheld at the time Social Security, Medicare and other wage withholding taxes are due. 
 (c) Compliance with Section 409A. Issuance of shares of Common Stock under this Agreement shall be made in accordance with the provisions of Section 409A and, to the extent that such shares are issued in connection with
your Separation from Service for any reason other than death, such issuance shall be delayed for six months and one day to the extent the Committee determines that such delay is necessary to avoid adverse or unintended tax consequences to you under
Section 409A. 
 6. Separation from Service Other than by Reason of Retirement, Disability or Death; Forfeiture; Default Payment.

 (a) Prior to Conversion Date. If you incur a Separation from Service prior to the Conversion Date for any reason other than
Retirement, Disability or death, you shall forfeit all rights to all Units granted hereunder, and such Units shall, for all purposes of the Plan and this Agreement, be deemed terminated and without further force or effect as of the date of such
Separation from Service. 
 (b) On or After Conversion Date. If you incur a Separation from Service on or after the Conversion Date
for any reason other than Retirement, Disability or death, the shares that are earned under this Agreement, but have not then been issued to you, shall be issued to you in accordance with Paragraph 5 as of the Payments Date(s) specified below:

 (i) No Payment/Re-Deferral Election. If you did not make a Payment Election or Re-Deferral Election, as the case may
be, the shares of Common Stock shall be issued in a lump sum as of the Conversion Date. 
 (ii) Payment/Re-Deferral
Election. If you made a Payment Election or Re-Deferral Election with respect to the shares earned under this Agreement, the shares subject to your Payment Election or Re-Deferral Election, as the case may be, that are earned but have not then
been issued to you shall be issued to you, in accordance with Paragraph 5, in a lump sum as of the first day of the month immediately following the month in which your Separation from Service occurs, regardless of the Payment Date(s) specified in
your Payment Election or Re-Deferral Election.

month immediately following the month in which your Separation from Service occurs, if it is by reason of Retirement or Disability, and as soon as practicable following your Separation from Service, if it is by reason of death, but in no event later
than the Conversion Date.

Election or Re-Deferral Election with respect to such shares and the Separation from Service is by reason of Retirement or Disability, the shares subject to such Payment Election or Re-Deferral Election, as the case may be, shall be issued to you,
your legal representative or other person designated by an appropriate court as entitled to take receipt thereof, as the case may be, as of the Payment Date(s) specified in your Payment Election or Re-Deferral Election. 
 (iii) Payment/Re-Deferral Election—Death. Notwithstanding anything in this Paragraph 7(a) to the contrary, if your Separation
from Service is by reason of death or you die after a Separation from Service by reason of Retirement or Disability and, in either such case, you have shares of Common Stock subject to your Payment Election or Re-Deferral Election, as the case may
be, that have not then been issued to you, such shares shall be issued to your Beneficiary in a lump sum as soon as practicable following the date of your death, regardless of the Payment Date(s) specified in your Payment Election or Re-Deferral
Election. 
 (b) On or After Conversion Date. If you incur a Separation from Service on or after the Conversion Date by reason of
Retirement, Disability or death, the shares of Common Stock, if earned, in respect of the Units granted hereunder shall be issued in accordance with Paragraph 5 as of the Payment Date(s) specified below: 
 (i) No Payment/Re-Deferral Election. If you did not make a Payment Election or Re-Deferral Election with respect to such shares,
the shares of Common Stock shall be issued to you, your legal representative or other person designated by an appropriate court as entitled to take receipt thereof or your Beneficiary, as the case may be, in a lump sum as of the first day of the
month immediately following the month in which your Separation from Service occurs, if it is by reason of Retirement or Disability, and as soon as practicable following your Separation from Service, if it is by reason of death. 
 (ii) Payment/Re-Deferral Election—Retirement, Disability. If you incur a Separation from Service on or after the Conversion
Date by reason of Retirement or Disability and you have shares of Common Stock subject to a Payment Election or 

  

 - 4 - 

 
Re-Deferral Election, as the case may be, that have not then been issued to you, such shares shall be issued to you, your legal representative or other
person designated by an appropriate court as entitled to take receipt thereof, as the case may be, in accordance with Paragraph 5 as of the Payment Date(s) specified in your Payment Election or Re-Deferral Election. 
 (iii) Payment/Re-Deferral Election—Death. Notwithstanding anything in Paragraph 7(b)(ii) to the contrary, if you incur a
Separation from Service on or after the Conversion Date by reason of death or you die after a Separation from Service by reason of Retirement or Disability and, in either such case, you have shares of Common Stock subject to a Payment Election or
Re-Deferral Election, as the case may be, that have not then been issued to you, such shares shall be issued to your Beneficiary, in accordance with Paragraph 5, in a lump sum as soon as practicable following the date of your death, regardless of
the Payment Date(s) specified in your Payment Election or Re-Deferral Election. 
 8. Distribution in the Event of Financial Hardship.

 (a) Requirements. If you incur a Separation from Service by reason of Retirement or Disability and you have shares of Common Stock
subject to a Payment Election or Re-Deferral Election, as the case may be, that have not then been issued to you, you may submit a written request for an accelerated issuance of such shares in the event you experience an Unforeseeable Financial
Emergency. The Hardship Committee shall evaluate any such request as soon as practicable in accordance with Section 409A. If the Hardship Committee determines in its sole discretion that you are experiencing such an Unforeseeable Financial
Emergency, the Hardship Committee shall direct the Company to issue to you, as soon as practicable following such determination, such number of shares of Common Stock held for your account in the Restricted Stock Trust, provided that the
value of such shares of Common Stock does not exceed the amount needed to satisfy the Unforeseeable Financial Emergency and the tax liability reasonably anticipated as a result of such issuance of shares. In making its determination, the Hardship
Committee shall take into account the extent to which such Unforeseeable Financial Emergency is, or may be, relieved through reimbursement or compensation by insurance or otherwise or by liquidation of your assets (to the extent the liquidation of
such assets would not itself cause severe financial hardship). 
 (b) Distribution Procedures. For purposes of this Paragraph 8, the
value of the shares of Common Stock shall be calculated based on the average of the high and low share prices for the Common Stock as reported on the Consolidated Transaction Reporting System on the trading day immediately preceding the date of
approval by the Hardship Committee. You must provide adequate documentation to the Hardship Committee in order to be eligible for the issuance of shares to confirm the amount needed to satisfy the costs related to the Unforeseeable Financial
Emergency and the taxes payable on the release of such shares. If you have elected, pursuant to Paragraph 4, to receive the shares of Common Stock subject to this Agreement in the form of installments, the number of shares issued to you due to the
Unforeseeable Financial Emergency pursuant to this Paragraph 8 shall be deducted from the remaining installments to be issued to you starting with the last in time of such installments scheduled to be issued. 
 9. Miscellaneous. This Agreement may not be amended except in writing. Neither the existence of the Plan and this Agreement nor the award granted
hereby shall create any right to continue to be employed by the Company or its subsidiaries, and your employment shall 
  

 - 5 - 

 
continue to be at will and terminable at will by the Company. In the event of a conflict between this Agreement and the Plan, the Plan shall govern;
provided, however, that nothing in this Paragraph 9 shall be construed as requiring that any such conflict be resolved in a manner that the Company determines would be inconsistent with Section 409A or would result in adverse or
unintended tax consequences to you under Section 409A. To the extent that the Committee or the Hardship Committee is authorized to make a determination under this Agreement, all such determinations shall be in the sole discretion of the
Committee, the Hardship Committee or their respective delegates.
