Stock Option Plan for Non-Employee Directors, as amended through Nov. 16, 2006

 Exhibit 10.38 
 WYETH 
 STOCK OPTION PLAN 
 FOR NON-EMPLOYEE DIRECTORS 
 (Effective as of March 2, 1999 and as amended by
the 
 Board of Directors through November 16, 2006) 
 1. Purpose. The purpose of the Wyeth Stock Option Plan for Non-Employee Directors (the “Plan”) is to attract and retain qualified persons who are not employees or former employees of Wyeth (the
“Company”) or any of its subsidiaries or affiliates for service as members of the Board of Directors of the Company by providing such members with an interest in the Company’s success and progress by granting them non-qualified
options (“Options”) to purchase shares of the Company’s common stock, par value $.33 1/3 per share (the “Common Stock”). 
 2. Administration. The Plan shall be administered by the Compensation and Benefits Committee or any successor thereto (the “Committee”) of the Board of Directors (the “Board”) of the
Company. Questions involving eligibility for grants of Options, entitlement to Options or the operation of the Plan shall be referred to the Committee. All determinations of the Committee shall be conclusive. The Committee may obtain such advice or
assistance as it deems appropriate from persons not serving on the Committee. 
 3. Eligibility and Grants. To be eligible to
participate in the Plan, a director must not be an employee or former employee of the Company or any of its subsidiaries or affiliates. On the date in each calendar year of the Annual Meeting of Stockholders of the Company, each eligible director
elected at such Annual Meeting shall automatically be granted an Option to purchase 3,000 shares of Common Stock; provided, however, that such amount may be increased or decreased by the Committee in the first calendar quarter of each year to
reflect the competitive environment with respect to director compensation. Each eligible director to whom Options are granted is hereinafter referred to as a “Participant.” Each grant of Options shall be evidenced by a written agreement
duly executed and delivered by or on behalf of the Company and the Participant. 
 4. Shares Available. Subject to adjustment as
provided in Section 10, the maximum aggregate number of shares of Common Stock which shall be available under the Plan for the issuance upon the exercise of Options is 250,000 shares. 
 5. Term of Options. Each Option granted under the Plan shall have a term of ten years from the date of grant, subject to earlier termination as
provided in Section 8. 
 6. Option Price. Options are priced at 100% of the fair market value of the Common Stock on the date of
grant. Such price shall be subject to adjustment as provided in Section 10. The fair market value of a share of Common Stock 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 (“Fair Market Value”). 

 7. Exercise of Options. (a) Subject to Section 8, each Option shall become 100%
exercisable on the later of (i) the date upon which the Participant has served one term-year as a member of the Board since the date the Option was granted (which for these purposes shall mean the period from one Annual Meeting to the
subsequent Annual Meeting), and (ii) the date on which the Participant completes two years of continuous service as a director. 
 (b)
An Option may be exercised at any time or from time to time, as to any or all full shares of Common Stock as to which the Option is then exercisable; provided, however, that any such exercise shall be for at least 100 shares of Common Stock or, if
less, the total number of shares of Common Stock as to which the Option is then exercisable. 
 (c) The purchase price of the Common Stock as
to which an Option is exercised shall be paid in full at the time of exercise; payment may be made in cash or in shares of Common Stock valued at the number of shares to be purchased multiplied by the option price per share or in any other form of
consideration which has been approved by the Committee under the most recent stock option or incentive plan applicable to the executive officers of the Company (the “Stock Incentive Plan”). 
 8. Completion of Directorship. (a) In the event of the death of a Participant or the termination of a Participant’s service as a
director upon retirement after having attained age 65 with at least 10 years of service or on account of disability, any outstanding Options held by a Participant who has completed at least two years of continuous service as a director which are not
yet exercisable shall become exercisable on the day following the date of (i) death; (ii) retirement; or (iii) termination of the Participant’s service as a director by reason of disability, as the case may be, and all
outstanding Options held by such Participant shall remain exercisable until the tenth anniversary of the date of grant. 
 (b) In the event
of a resignation or a termination of the service of a Participant from the Board (i) for any reason prior to the completion of two years of continuous service as a director; or (ii) thereafter, for any reason other than death, disability
or retirement as contemplated under subsection (a) above, any outstanding Options held by such Participant shall expire at the close of business on the effective date of such resignation or termination; provided, however, that the Board may, in
its discretion, cause the Options of such Participant to become exercisable, and/or to remain exercisable, for a period of time subsequent to such resignation or termination, but in no event may the Options remain exercisable after the tenth
anniversary of the date of grant. 
 9. Regulatory Compliance and Listing. The issuance or delivery of any shares of Common Stock upon
the exercise of Options may be postponed by the Company for such period as may be required to comply with any applicable requirements under the federal securities laws, any applicable listing requirements of any national securities exchange and
requirements under any other law or regulation applicable to the issuance or delivery of such shares, and the Company shall not be obligated to issue or deliver any shares of Common Stock if the issuance or delivery of such shares shall constitute a
violation of any provision of any law or of any rule or regulation of any governmental authority or any national securities exchange. 
  

 2 

 10. Adjustment in Event of Changes in Capitalization. In the event of a recapitalization, stock
split, stock dividend, combination or exchange of shares, merger, consolidation, rights offering, separation, reorganization or liquidation, or any other change in the corporate structure or shares of the Company, the number of shares of Common
Stock that may be awarded as Options or that are subject to outstanding Option grants, and the option price per share under outstanding Options, shall be adjusted automatically to prevent dilution or enlargement of rights. 
 11. Termination or Amendment of the Plan. The Board may at any time terminate the Plan and may from time to time alter or amend the Plan or any
part thereof (including any amendment deemed necessary to ensure that the Company may comply with any regulatory requirement referred to in Section 9), provided that, unless otherwise required by law, the rights of a Participant with respect to
Options granted prior to such termination, alteration or amendment may not be impaired without the consent of such Participant. 
 12.
Miscellaneous. (a) Nothing in the Plan shall be deemed to create any obligation on the part of the Board to nominate any director for reelection by the Company’s shareholders. 
 (b) The Company shall have the right to require, prior to the issuance or delivery of any Common Stock upon the exercise of Options, payment by the
Participant of any taxes required by law with respect to the issuance or delivery of such shares. Such amount may be paid in cash, in shares of Common Stock previously owned by the Participant (based on the Fair Market Value), or a combination of
cash and shares of Common Stock. 
 (c) The shares of Common Stock to be issued upon the exercise of Options under the Plan shall, unless
otherwise determined by the Committee, be shares which have been or may be reacquired by the Company. 
 (d) The Options granted hereunder
shall not be transferable by the Participants hereunder otherwise than by will or the laws of descent and distribution except to the extent permitted under the Stock Incentive Plan with respect to executive officers of the Company. 
 (e) This Plan and Options granted hereunder shall be governed by and construed in accordance with the laws of Delaware and in accordance with such
federal laws as may be applicable. 
 13. Change in Control. Upon the occurrence of a Change in Control, all Options granted under the
Plan as of the date of such occurrence (which have not previously expired) will become vested and exercisable and, notwithstanding the provisions of Section 8(b) of the Plan or any other provisions to the contrary, will remain exercisable until
the tenth anniversary of the date of grant. Furthermore, upon the occurrence of a Change in Control, the Committee, in its sole discretion and without liability to any person, may take such other actions, if any, as it deems necessary or desirable
with respect to any Options granted hereunder so as to substantially preserve the value, rights and benefits thereof. For purposes of this provision, a Change in Control will be deemed to have occurred if: 
  

 3 

 (a) any person or persons acting in concert (excluding Company benefit plans) becomes the beneficial
owner of securities of the Company having at least 20% of the voting power of the Company’s then outstanding securities (unless the event causing the 20% threshold to be crossed is an acquisition of voting common securities directly from the
Company); or 
 (b) the consummation of any merger or other business combination of the Company, sale or lease of the Company’s assets
or combination of the foregoing transactions (the “Transactions”) other than a Transaction immediately following which the shareholders of the Company who owned shares immediately prior to the Transaction (including any trustee or
fiduciary of any Company employee benefit plan) own, by virtue of their prior ownership of the Company’s shares, at least 65% of the voting power, directly or indirectly, of (a) the surviving corporation in any such merger or other
business combination; (b) the purchaser or lessee of the Company’s assets; or (c) both the surviving corporation and the purchaser or lessee in the event of any combination of Transactions; or 
 (c) within any 24 month period, the persons who were directors immediately before the beginning of such period (the “Incumbent Directors”)
shall cease (for any reason other than death) to constitute at least a majority of the Board or the board of directors of a successor to the Company. For this purpose, any director who was not a director at the beginning of such period shall be
deemed to be an Incumbent Director if such director was elected to the Board by, or on the recommendation of or with the approval of, at least two–thirds of the directors who then qualified as Incumbent Directors (so long as such director was
not nominated by a person who has expressed an intent to effect a Change in Control or engage in a proxy or other control contest).

 The rights of any person who

 The restated Plan contained herein shall apply to Participants, Beneficiaries of such Participants or alternate payees, who retire, die or terminate employment at any time on or after January 1, 2006 unless a later effective date for

then a contribution equal to the amount which it is prevented from making for such year may be made by the Company if it is not prevented from contributing for such year. The foregoing proviso shall be interpreted in accordance with

other eligible Employees who are Non-Highly Compensated Employees for the current Plan Year by more than two (2) percentage points. 

 In applying the foregoing limitations, an Employee is a Highly Compensated Employee for a particular Plan Year if he meets the definition of a Highly Compensated Employee in effect for that Plan Year. Similarly, an
Employee is a Non-Highly Compensated Employee for a particular Plan Year if he does not meet the definition of a Highly Compensated Employee in effect for that Plan Year. The Actual Deferral Percentage for a specified group of Employees for an
applicable Plan Year shall be the average of ratios (calculated separately for each Employee in such group) of (1) the amount of Salary-Deferral Contributions actually paid over to the Trust on behalf of each such Employee for such Plan Year,
to (2) the Employee’s Compensation for that portion of the applicable Plan Year during which the Employee was eligible to participate. In computing the Actual Deferral Percentage, Salary-Deferral Contributions shall not include any amounts
properly returned to (3) the Participant as excess Annual Additions under Article Eleven of the Plan; or (4) a Non-Highly Compensated Employee as Excess Salary-Deferral

Contributions used in the Average Contribution Percentage test. 
 The Actual Deferral Percentage for any Employee who is a Highly Compensated
Employee for the Plan Year and who has Salary-Deferral Contributions allocated to his account under two or more plans of an Employer, shall be determined as if all such contributions were made under a single plan. If the above plans have different
plan years, all cash or deferred arrangements ending with or within the same calendar year shall be treated as a single arrangement. 
 In the
event that this Plan satisfies the requirements of Section 401(k), 401(a)(4) or 410(b) of the Code only if aggregated with one or more other plans, or if one or more other plans satisfy the requirements of Section 401(k), 401(a)(4) or
410(b) of the Code only if aggregated with this Plan, then this Section 4.9 of the Plan shall be applied by determining the Actual Deferral Percentages of Participants as if all such plans were a single plan. Plans may be aggregated to satisfy
Section 401(k) of the Code only if they have the same plan year and use the same Actual Deferral Percentage testing method. 
 An
Employer shall maintain records sufficient to demonstrate satisfaction of the Actual Deferral Percentage test. The determination and treatment of the Actual Deferral Percentage amounts of any Participant shall satisfy such other requirements as may
be prescribed by the Secretary of the Treasury. 
  

	 	(b)	 Excess Contributions. Notwithstanding the foregoing paragraph, with respect to any Plan Year in which Salary-Deferral Contributions on behalf of
Highly Compensated Employees exceed the applicable limit, the Plan Administrator shall reduce the amount of the Excess Contributions made on behalf of the Highly Compensated Employees (determined by reducing such contributions in order of actual
deferral percentages beginning with the highest), and shall distribute any Excess Contributions which exist after such reduction, as adjusted by the Income or loss allocable to such Excess Contributions, to the affected Highly Compensated Employees
no later than March 15 of the year following the Plan Year in which any such Excess Contributions arose, but in no event shall such amounts be distributed later than the end of the Plan Year following the Plan Year for which such Excess
Contributions were allocated. Excess Contributions are allocated to the Highly Compensated Employees with the largest amount of Salary-Deferral Contributions taken into account in calculating the Actual Deferral Percentage test for the year in which
the excess arose, beginning with the Highly Compensated Employee with the largest amount of Salary-Deferral Contributions and continuing in descending order 

  

 21 

			
	Article 4	  	Contributions

 
until all Excess Contributions have been allocated. For purposes of the preceding sentence, the “largest amount” is determined after distribution
of any Excess Contributions. 
 For purposes of this Section 4.9(b) of the Plan, “Excess Contributions” shall mean, with
respect to any Plan Year, the aggregate amount of Employer contributions actually taken into account in computing the Actual Deferral Percentage of the Highly Compensated Employees over the maximum amount of such contributions permitted by the
Actual Deferral Percentage test. The Income or loss allocable to the Excess Contributions shall be the amount determined by multiplying the Income or loss allocable to the Participant’s accounts containing the Excess Contributions for the Plan
Year by a fraction, the numerator of which is the Excess Contributions on behalf of the Participant for the Plan Year and the denominator of which is the Participant’s account balance in his accounts containing the Excess Contributions as of
the Valuation Date of the Plan Year in which the Excess Contribution is made without regard to any gain or loss allocable to such total amount for the Plan Year. 
 For the 2006 and 2007 Plan Years, Excess Contributions shall be adjusted for any Income or loss during the GAP Period as defined in Section 4.5 of the Plan. The Income or loss allocable to Excess Contributions
during the GAP Period is the sum of: (i) the Income or loss allocable to the Participant’s Salary-Deferral Contribution Account for the Plan Year multiplied by a fraction, the numerator of which is such Participant’s Excess
Contributions for the year and the denominator is the Participant’s account balance attributable to Salary-Deferral Contributions as of the beginning of the Plan Year and Salary-Deferral Contributions made during the Plan Year; and (ii) 10
percent of the amount determined under (i) multiplied by the number of whole calendar months between the end of the Plan Year and the date of distribution, counting the month of distribution if distribution occurs after the 15th of such month.

 4.10 Limitation on After-Tax Contributions and Matching Contributions 
  

	 	(a)	Actual Contribution Percentage Test. An Employer shall not make Matching Contributions to the Plan which would cause the Plan not to satisfy at least one of the
following tests in any Plan Year: 

  

	 	(i)	The Average Contribution Percentage for a Plan Year for the group of Highly Compensated Employees shall not exceed the current year’s Average Contribution Percentage for all
other eligible Employees who are Non-Highly Compensated Employees in the current Plan Year multiplied by 1.25; or 

  

	 	(ii)	 The Average Contribution Percentage for a Plan Year for the group of Highly Compensated Employees shall not exceed the current year’s Average Contribution
Percentage for all other eligible Employees who are Non-Highly Compensated Employees in the current Plan Year multiplied by 2.0, provided that the Average Contribution Percentage for the group of 

  

 22 

			
	Article 4	  	Contributions

	 	 
Highly Compensated Employees does not exceed the Average Contribution Percentage for all other eligible Employees who are Non-Highly Compensated Employees in
the current Plan Year by more than two (2) percentage points. 

 A Participant is a Highly Compensated Employee for a
particular Plan Year if he meets the definition of a Highly Compensated Employee in effect for that Plan Year. Similarly, a Participant is a Non-Highly Compensated Employee for a particular Plan Year if he does not meet the definition of a Highly
Compensated Employee in effect for that Plan Year. For purposes of this Section 4.10 of the Plan, the Average Contribution Percentage for a specified group of Employees shall be the average of the ratios (calculated separately for each Employee
in the group) of (i) the matching contributions under the Plan on behalf of the Employee for the applicable Plan Year, to (ii) the Employee’s Compensation for that portion of the applicable Plan Year during which the Employee was
eligible to participate. For purposes of this Section 4.10 of the plan, the Contribution Percentage for any Participant who makes no After-Tax Contributions or does not receive a Matching Contribution shall be 0%. For purposes of determining
Contribution Percentages, Salary-Deferral Contributions are considered to have been made in the Plan Year in which contributed to the Trust. 
 Contributions shall be considered made for a Plan Year if made no later than the end of the twelve-month period beginning on the day after the close of the Plan Year. In computing Contribution Percentages, the Plan Administrator may include
Excess Salary-Deferral Contributions, except for Excess Salary-Deferral Contributions which are properly distributed as excess Annual Additions. 
 In computing Contribution Percentages, the Plan Administrator shall not include Matching Contributions that are forfeited either to correct Excess Aggregate Contributions or because the contributions to which the Matching Contributions
relate are Excess Salary-Deferral Contributions, Excess Contributions or Excess Aggregate Contributions. 
 In the event that this Plan
satisfies the requirements of Section 401(m), 401(a)(4) or 410(b) of the Code only if aggregated with one or more other plans, or if one or more other plans satisfy the requirements of Section 401(m), 401(a)(4) or 410(b) of the Code only
if aggregated with this Plan, then this Section 4.10 of the Plan shall be applied by determining the Contribution Percentages of Participants as if all such plans were a single plan. Plans may be aggregated in order to satisfy
Section 401(m) of the Code only if they have the same Plan Year and use the same Average Contribution Percentage testing method. 
 In
the event that the Actual Contribution Percentage for Highly Compensated Employees exceeds the percentage permitted above, the excess aggregate Matching Contributions and After-Tax Contributions, if any, attributable to each Highly Compensated
Employee shall be determined above. The portion of the excess which consists of After-Tax Contributions (together with the Income, or 

  

 23 

			
	Article 4	  	Contributions

 
less the loss, allocable to such contributions) shall be distributed first. The Employee shall forfeit all or a sufficient portion of such amount as consists
of Matching Contributions (together with the Income, or less the loss, allocable to such contributions). The Plan Administrator shall direct the Trustee to distribute not later than the next following March 15 to the Employee such designated
amount (together with any Income, or reduced by any loss, allocable to it). The Income or loss allocable to the Employee’s forfeited Matching Contributions or his designated amount of After-Tax Contributions shall be determined by multiplying
the Income or loss allocable for the Plan Year to the Employee’s total Matching Contributions (or his Additional After-Tax Contributions) for the Plan Year and the denominator of which is the sum of the Participant’s account balances
attributable to Matching Contributions (or After-Tax Contributions) on the last day of the Plan Year. 
  

	 	(b)	Excess Aggregate Contributions. “Excess Aggregate Contributions” shall mean, with respect to any Plan Year, the excess of the aggregate amount taken into
account in computing the numerator of the Contribution Percentage actually made on behalf of Highly Compensated Employees for such Plan Year, over the maximum aggregate amount permitted by the Average Contribution Percentage test (determined by
reducing contributions made on behalf of Highly Compensated Employees in order of their Contribution Percentages beginning with the highest of such percentages). The determination of Excess Aggregate Contributions shall be made pursuant to this
Section 4.10 of the Plan. The Excess Aggregate Contributions to be distributed to a Participant shall be adjusted by the Income or loss allocable to such Excess Aggregate Contribution. The Income or loss allocable to the Excess Aggregate
Contributions shall be the amount determined by multiplying the Income or loss allocable to the Participant’s Account containing the excess amounts for the Plan Year by a fraction, the numerator of which is the Excess Aggregate Contributions on
behalf of the Participant for the Plan Year and the denominator of which is the Participant’s account balance in the accounts containing the excess amounts as of the last Valuation Date of the Plan Year in which the Excess Aggregate
Contribution is made without regard to any gain or loss allocable to such total amount. 

 For the 2006 and 2007 Plan Years,
Excess Aggregate Contributions shall be adjusted for any Income or loss during the GAP Period as defined in Section 4.5 of the Plan. The Income or loss allocable to Excess Aggregate Contributions during the GAP Period is the sum of:
(1) the Income or loss allocable to the Participant’s After-Tax Contributions Account and Matching Contributions Account, and if applicable, Salary-Deferral Contributions Account for the Plan Year (provided such accounts are not used in
the ADP test) multiplied by a fraction, the numerator of which is such Participant’s Excess Aggregate Contributions for the year and the denominator is the Participant’s account balance(s) attributable to the Excess Aggregate Contribution
amounts without regard to any Income or loss occurring during such Plan Year; and (2) 10 percent of the amount determined under (1) multiplied by the number of whole calendar months between the end of the Plan Year and the date of
distribution, counting the month of distribution if distribution occurs after the 15th of such month.

	Article 4	  	Contributions

 4.11 Rollover Contributions From Other Qualified Plans 
 A Participant, with the approval of the Plan Administrator (or its delegate) and upon a determination by the Plan Administrator that a distributing plan
is an Eligible Retirement Plan, may make, and that Plan shall accept, a Rollover Contribution on the Participant’s behalf. The Rollover Contributions shall be subject to all of the terms and conditions of the Plan after it is rolled over, and
shall be fully vested at all times. The Rollover Contribution shall be deposited in the Participant’s Rollover Account and invested in accordance with the Participant’s investment elections in effect at the time of the Rollover
Contribution. The Plan Administrator (or its delegate) may require a Participant to furnish such evidence as the Plan Administrator may deem necessary or appropriate. 
 For purposes of this Section 4.11 of the Plan, a Rollover Contribution means an Eligible Rollover Distribution within the meaning of Section 402(c)(4) of the Code; and 
  

	 	(a)	A contribution by a Participant of a distribution received from a qualified defined contribution plan described in Section 401(a) or 403(a) of the Code, including After-Tax
Contributions, provided the Participant makes the contribution within 60 days of his receipt of a distribution which satisfied the requirements of Section 402(c)(1) of the Code; or 

  

	 	(b)	A direct transfer of the Participant’s interest from the trustee of a qualified defined contribution plan described in Section 401(a) or 403(a) of the Code, including
after tax contributions. 

 The Plan Administrator shall accept
distributions made from any defined benefit pension plan maintained by the Company which is qualified under Section 401(a) of the Code provided, however, if the distribution is payable to the Participant, the Rollover Contribution must be
received by the Plan no later than the 60th day after the distribution was payable to the Participant.

 4.12 Automatic Enrollment 
  

	 	(a)	This Section 4.12 of the Plan shall apply to Employees who become Participants in the Plan on or after January 1, 2007 and Employees (including Former Participants) who
are reemployed by an Employer on or after January 1, 2007. 

  

	 	(b)	Each Participant who does not affirmatively elect to, or not to, make Salary-Deferral Contributions or After-tax Contributions to the Plan shall automatically have his before-tax
Covered Compensation reduced by 3% and have such amount contributed to the Plan as Salary-Deferral Contributions beginning with the first day of the first administratively practicable payroll period following the date the employee becomes a
Participant. 

  

	 	(c)	Each year thereafter, such Participant shall be deemed to have elected to increase his Salary-Deferral Contribution election by one percent (1%) per year until his
Salary-Deferral Contribution level is six percent (6%) of his Covered Compensation. 

  

	 	(d)	Absent a direction by the Participant pursuant to Article Seven of the Plan, Salary-Deferral Contributions made pursuant to this Section 4.12 of the Plan shall be invested in a
default Investment Fund designated by the Plan Administrator from time to time. 

  

	 	(e)	This Section 4.12 of the Plan shall cease to apply to a Participant who makes election to increase or decrease the amount of, or cease making, Salary-Deferral Contributions to
the Plan.

the After-Tax Contributions Account and the Matching Contributions Account and the Rollover Account. 
 6.2 Separate Accounting

 The amounts in a Participant’s Salary-Deferral Account, QVEC Account, After-Tax Contributions Account, Matching Contributions

Beneficiary designation may be changed at any time and shall cease to be effective if he thereafter becomes married. To be effective, the original designation of the Beneficiary and any subsequent change must be in writing on the form provided for
that purpose by the Plan Administrator and on file with the Plan Administrator at the date of death of the Participant. The Plan Administrator shall not recognize any Beneficiary designation or change in a Beneficiary designation unless the
designation or change is in writing and on file with the Plan Administrator on the date of the Participant’s death.

	 	(c)	Finally, if there are no surviving parents, to the legal representatives of the Participant’s estate. 

 8.6 Cash-Out 
 If a Participant
incurs a Severance From Employment, the vested portion of his Account shall be distributed to him if the value of his vested Account does not exceed $1,000. 
 8.7 Election of Wyeth Common Stock; Converting Common Stock to Cash. 
 If prior to the date of
distribution, in accordance with rules prescribed by the Plan Administrator, the Participant or other Distributee elects to receive the Wyeth Common Stock Fund portion of his Account in Common Stock, he shall receive the number of shares of Common
Stock in such Account. Otherwise, all distributions shall be in cash in a lump sum. Common Stock converted into cash shall be valued as the Valuation Date set forth in Section 6.3 of the Plan. Distribution shall be made as soon thereafter as is
practicable in accordance with rules prescribed by the Plan Administrator. 
 8.8 Time Distributions Are to Begin 

In general, distribution of a Participant’s Account shall begin not later than the sixtieth day after the later of the close of the Plan Year in
which: 
  

	 	(a)	Such Participant attains his Normal Retirement Age; or 

  

	 	(b)	Such Participant’s Severance from Employment occurs. 

 Subject to Section 8.9 of the Plan, no person subject to Section 16(b) of the Securities Exchange Act of 1934 shall receive a distribution earlier than six months from the date of his retirement or other Severance From Employment
unless the Plan Administrator in its discretion shall authorize an earlier distribution in accordance with this Section 8.8 of the Plan.

 8.9 Required Minimum Distributions 
  

	 	(a)	Time and Manner of Distribution. 

  

	 	(i)	Required Beginning Date. The Participant’s entire interest shall be distributed, or begin to be distributed, to the Participant no later than the Participant’s Required
Beginning Date. 

  

	 	(ii)	Death of a Participant Before Distributions Begin. If the Participant dies before distributions begin, the Participant’s entire interest shall be distributed, or begin to be
distributed, no later than as follows: 

  

	 	 (1)
	 If the Participant’s surviving Spouse is the Participant’s sole Designated Beneficiary, then distributions to
the surviving Spouse shall begin by December 31 of the calendar year immediately following the calendar year in which the Participant died, or by December 31 of the calendar year in which the Participant would have attained age 70 1/2, if later. 

  

	 	(2)	If the Participant’s surviving Spouse is not the Participant’s sole Designated Beneficiary, then distributions to the Designated Beneficiary shall begin by
December 31 of the calendar year immediately following the calendar year in which the Participant died. 

  

	 	(3)	If there is no Designated Beneficiary as of September 30 of the year following the year of the Participant’s death, the Participant’s entire interest shall be
distributed by December 31 of the calendar year containing the fifth anniversary of the Participant’s death. 

  

	 	(4)	If the Participant’s surviving Spouse is the Participant’s sole Designated Beneficiary and the surviving Spouse dies after the Participant but before distributions to the
surviving Spouse begin, this subsection (a)(ii), other than subsection (a)(ii)(1), shall apply as if the surviving Spouse were the Participant. 

 For purposes of this subsection (a)(ii) and subsection (iii), unless subsection (a)(ii)(4) applies, distributions are considered to begin on the Participant’s Required Beginning Date. If subsection (a)(ii)(4),
distributions are considered to begin on the date distributions are required to begin to the surviving Spouse under (a)(ii)(1). If distributions under an annuity purchased from an insurance company irrevocably commence to the Participant before the
Participant’s Required Beginning Date (or to the Participant’s surviving Spouse before the date distributions are required to begin to the surviving Spouse under subsection (a)(ii)(1), the date distributions are considered to begin is the
date distributions actually commence.

 (iii) Form of Distribution. Unless the Participant’s interest is distributed in the form of an
annuity purchased from an insurance company or in a single sum on or before the Required Beginning Date, as of the first Distribution Calendar Year distributions shall be made in accordance with subsections (b) and (c). If the
Participant’s interest is distributed in the form of an annuity purchased from an insurance company, distributions thereunder shall be made in accordance with the requirements of Section 401(a)(9) of the Code and the Treasury Regulations
thereunder. 
  

	(b)	Required Minimum Distributions During Participant’s Lifetime. 

  

	 	(i)	Amount of Required Minimum Distributions For Each Distribution Calendar Year. During the Participant’s lifetime, the minimum amount that shall be distributed for each
Distribution Calendar Year is the lesser of: 

  

	 	(1)	The quotient obtained by dividing the Participant’s Account Balance by the distribution period in the Uniform Lifetime Table set forth in Treasury Regulation
Section 1.401(a)(9)-9, using the Participant’s age as of the Participant’s birthday in the Distribution Calendar Year; or 

  

	 	(2)	If the Participant’s sole Designated Beneficiary for the Distribution Calendar Year is the Participant’s Spouse, the quotient obtained by dividing the Participant’s
Account Balance by the number in the Joint and Last Survivor Table set forth in Treasury Regulation Section 1.401(a)(9)-9, using the Participant’s and the Spouse’s attained ages as of the Participant’s and Spouse’s birthdays
in the Distribution Calendar Year. 

  

	 	(ii)	Lifetime Required Minimum Distributions Continue Through Year of Participant’s Death. Required minimum distributions shall be determined under this subsection
(b) beginning with the first Distribution Calendar Year and up to and including the Distribution Calendar Year that includes the Participant’s date of death. 

  

	(c)	Required Minimum Distributions After Participant’s Death. 

  

	 	(i)	Death On or After Date Distributions Begin. 

  

	 	(1)	Participant Survived by Designated Beneficiary. If the Participant dies on or after the date distributions begin and there is a Designated Beneficiary, the minimum amount that shall
be distributed for each Distribution Calendar Year after the year of the Participant’s death is the quotient obtained by dividing the Participant’s Account Balance by the longer of the remaining life expectancy of the Participant or the
remaining life expectancy of the Participant’s Designated Beneficiary, determined as follows: 

  

 37 

			
	Article 8	  	Distributions

	 	(A)	The Participant’s remaining life expectancy is calculated using the age of the Participant in the year of death, reduced by one for each subsequent year.

  

	 	(B)	If the Participant’s surviving Spouse is the Participant’s sole Designated Beneficiary, the remaining life expectancy of the surviving Spouse is calculated for each
Distribution Calendar Year after the year of the Participant’s death using the surviving Spouse’s age as of the Spouse’s birthday in that year. For Distribution Calendar Years after the year of the surviving Spouse’s death, the
remaining life expectancy of the surviving Spouse is calculated using the age of the surviving Spouse as of the Spouse’s birthday in the calendar year of the Spouse’s death, reduced by one for each subsequent calendar year.

  

	 	(C)	If the Participant’s surviving Spouse is not the Participant’s sole Designated Beneficiary, the Designated Beneficiary’s remaining life expectancy is calculated using
the age of the Designated Beneficiary in the year following the year of the Participant’s death, reduced by one for each subsequent calendar year. 

  

	 	(2)	No Designated Beneficiary. If the Participant dies on or after the date distributions begin and there is no Designated Beneficiary as of the September 30 of the year after the
year of the Participant’s death, the minimum amount that shall be distributed for each Distribution Calendar Year after the year of the Participant’s death is the quotient obtained by dividing the Participant’s Account Balance by the
Participant’s remaining life expectancy calculated using the age of the Participant in the year of death, reduced by one for each subsequent year. 

  

	 	(ii)	Death Before Date Distributions Begin. 

  

	 	(1)	Participant Survived by Designated Beneficiary. If the Participant dies before the date distributions begin and there is a Designated Beneficiary, the minimum amount that shall be
distributed for each Distribution Calendar Year after the year of the Participant’s death is the quotient obtained by dividing the Participant’s Account Balance by the remaining life expectancy of the Participant’s Designated
Beneficiary, determined as provided in subsection (c)(i). 

  

 38 

			
	Article 8	  	Distributions

	 	(2)	No Designated Beneficiary. If the Participant dies before the date distributions begin and there is no Designated Beneficiary as of September 30 of the year following the year
of the Participant’s death, distribution of the Participant’s entire interest shall be completed by December 31 of the calendar year containing the fifth anniversary of the Participant’s death. 

  

	 	(3)	Death of Surviving Spouse Before Distributions to Surviving Spouse Are Required To Begin. If the Participant dies before the date distributions begin, the Participant’
surviving Spouse is the Participant’s sole Designated Beneficiary, and the surviving Spouse dies before distributions are required to begin to the surviving Spouse under subsection (a)(ii)(1), this subsection (c)(ii) shall apply as if the
surviving Spouse were the Participant. 

  

	 	(d)	Definitions.

	 	(ii)	Distribution Calendar Year. A calendar year for which a minimum distribution is required. For distributions beginning before the Participant’s death, the first Distribution
Calendar Year is the calendar year immediately preceding the calendar year which contains the Participant’s Required Beginning Date. For distributions beginning after the Participant’s death, the first Distribution Calendar Year is the
calendar year in which distributions are required to begin pursuant to subsection (a)(ii). The required minimum distribution for the Participant’s first Distribution Calendar Year shall be made on or before the Participant’s Required
Beginning Date. The required minimum distribution for other Distribution Calendar Years, including the required minimum distribution for the Distribution Calendar Year in which the Participant’s Required Beginning Date occurs, shall be made on
or before December 31 of that Distribution Calendar Year. 

  

	 	(iii)	Life Expectancy. Life expectancy as computed by use of the Single Life Table in Section 1.401(a)(9)-9 of the Treasury Regulations. 

  

	 	(iv)	 Participant’s Account Balance. The Account Balance as of the last valuation in the calendar year (valuation calendar year) increased by the amount of any

can be ascertained or the date on which the Participant or Beneficiary is located. 
 If after reasonable effort the Plan Administrator
cannot locate the Participant or Beneficiary, the Participant’s Account shall be forfeited. The amount of such forfeiture shall reduce the Matching Contribution required to be made by am Employer. Any such forfeited Account shall be reinstated

qualification requirements of the Code. 
 8.13 Rollover of Eligible Rollover Distributions From the Plan. 
  

	 	(a)	Notwithstanding any provision of the Plan to the contrary that would otherwise limit a Distributee’s election under this Section 8.13 of the Plan, as Distributee may
elect, at the time and in the manner prescribed by the Plan Administrator, to have any portion of an Eligible Rollover Distribution paid directly to an Eligible Retirement Plan specified by the Distributee in a Direct Rollover. However,
notwithstanding the above, the Plan Administrator may adopt procedures wherein the Plan shall not make a distribution pursuant to this Section 8.13 of the Plan unless the Eligible Rollover Distribution is at least $200, and that the Plan shall
directly rollover only a portion of an Eligible Rollover Distribution if the portion to be rolled over is at least $500. 

  

	 	(b)	If a distribution is one to which Sections 401(a)(11) and 417 of the Code do not apply, such distribution may commence less than 30 days after the notice required under
Section 1.411(a)-11(c) of the Income Tax Regulations is given, provided that: 

  

	 	(i)	The Plan Administrator clearly informs the Participant that the Participant has a right to a period of at least 30 days after receiving the notice to consider the decision of

	 	(c)	Representations of Participant. The Plan Administrator may rely upon the reasonable representations of the Qualifying Individual with respect to his principal place of abode
on August 25, 2005 and whether he suffered an economic loss due to Katrina. This reliance does not apply if the Plan Administrator has actual knowledge to the contrary. 

  

	 	(d)	Special Rules for QHKDs 

  

	 	(i)	A QHKD may be repaid to the Plan during a three-year period beginning the day after the date the QHKD is received by the Participant. The contributions may be repaid in one or more
deposits to the Plan. Such contributions shall be treated as a rollover contribution to the Plan made by a direct deposit made within 60 days of receipt. 

  

	 	(ii)	A QHKD shall be treated as if it is not eligible for a rollover. Therefore, it shall not be subject to the rollover distributions notice required under Section 402(f) of the
Code or to the 20% mandatory tax withholding.

 ARTICLE 9 WITHDRAWALS 
 9.1 Hardship Withdrawals 
 A Participant can withdraw amounts from his Salary-Deferral Account
(except Income attributable to the Salary-Deferral Account earned after January 1, 1989), Rollover Account and vested amounts in his Matching Contribution Account on account of a hardship. For the withdrawal to constitute a hardship, the
withdrawal (1) must be made on account of an immediate and heavy financial need of the Participant, and (2) must be necessary to satisfy that need. The determination of whether a Participant has an immediate and heavy financial need is to
be made by the Plan Administrator on the basis of all relevant facts and circumstances. A financial need shall not fail to qualify as immediate and heavy merely because such need was reasonably foreseeable or voluntarily incurred by the Participant.
The following types of expenses shall be deemed to constitute an immediate and heavy financial need for purposes of this Section 9.1 of the Plan: 
  

	 	(a)	Medical expenses (described in Section 213(d) of the Code) incurred by the Participant or his Spouse or dependents (as defined in Section 152 of the Code);

  

	 	(b)	Purchase (excluding mortgage payments) of a principal residence for the Participant; 

  

	 	(c)	Payment of tuition and related educational fees for the next 12 months of post-secondary education for the Participant, his Spouse, children or dependants; 

 

	 	(d)	To prevent the eviction of the Participant from his principal residence or foreclosure on the mortgage of the Participant’s principal residence; 

  

	 	(e)	The payment of burial or funeral expenses for the Participant’s deceased parent, Spouse, children or dependent (as defined in Section 152 of the Code, without regard to
Section 152(d)(1)(B) of the Code); or 

  

	 	(f)	Expenses for the repair of damage to a Participant’s principal residence that would qualify for the casualty deduction under Section 165 of the Code (determined without
regard to whether the loss exceeds 10% of adjusted gross income). 

  

	 	    	Other types of expenses that the Internal Revenue Service deems are immediate and heavy financial needs as set forth in the publication of revenue rulings, notices and other
documents of general applicability shall be deemed to constitute an immediate and heavy financial need for purposes of this Section 9.1 of the Plan. 

  

 43 

			
	Article 9	  	Withdrawals

 The requirement that a hardship withdrawal must be necessary to satisfy an immediate and heavy financial
need shall be met if the funds cannot be obtained from other resources reasonably available to the Participant and the amount distributed does not exceed the amount required to relieve the financial need. Before a Participant can make a hardship
withdrawal, he must first withdraw all amounts in his After-Tax Contributions Account available for withdrawal, and take out a loan on amounts in his Account, if available. To the extent that a Participant cannot access funds necessary to meet his
immediate and heavy financial need by a loan from his Plan Accounts or by a withdrawal of available amounts in his After-Tax Contributions Account, the Participant must do (a) and (b) as follows: 
  

	 	(a)	The Participant must furnish the Plan Administrator with a signed statement representing that the required funds cannot be obtained: 

  

	 	(i)	Through reimbursement or compensation by insurance; 

  

	 	(ii)	By reasonable liquidation of the Participant’s assets, to the extent such liquidation would not itself cause an immediate and heavy financial need; for this purpose, the
Participant’s assets shall be deemed to include those assets of the Participant’s Spouse and minor children that are reasonably available to the Participant; 

  

	 	(iii)	By discontinuing his Salary-Deferral Contributions and After-Tax Contributions to the Plan; or 

  

	 	(iv)	By borrowing from plans maintained by any other employer or by borrowing from commercial sources on reasonable commercial terms. 

  

	 	(b)	The Participant must suspend all Salary-Deferral Contributions (including Catch-Up Contributions) and After-Tax Contributions to the Plan. 

 A Participant shall notify the Plan Administrator in writing of his request to make a hardship withdrawal on a form provided by the Plan Administrator
pursuant to rules established by the Plan Administrator. Hardship withdrawals shall also meet the following requirements: 
  

 44 

			
	Article 9	  	Withdrawals

	 	(a)	No more than one hardship withdrawal per Plan Year shall be permitted. 

  

	 	(b)	The minimum hardship withdrawal shall be $500.00. 

  

	 	(c)	The hardship withdrawal shall not exceed the amount of the Participant’s Salary-Deferral Account, Rollover Account, and the vested portion of his Matching Contributions
Account. 

  

	 	(d)	The amount of the hardship withdrawal shall be deducted from the Participant’s Salary-Deferral Account, Rollover Account and Matching Contributions Account, as the case may be,
and the balance remaining after the withdrawal shall then constitute the total value of the Participant’s Salary-Deferral Account, Rollover Account and Matching Contributions Account. Hardship withdrawals shall first be made from the
Participant’s Salary-Deferral Account and when that is exhausted, may be made from the Rollover Account (until exhausted) and then from the vested portion of the Matching Contributions Account in that order. Such withdrawals shall be made from
the Investment Funds in Participant’s Accounts as designated by the Participant in writing to the Trustee/Recordkeeper. If a Participant fails to provide such instructions, each Account shall be charged proportionately based on the foregoing
sentences and on the status at the most recent Valuation Date with respect to the different investment options in the Accounts elected pursuant to Section 7.1 of the Plan. 

  

	 	(e)	All hardship withdrawals shall be made in cash. Conversion of Wyeth Common Stock to cash shall be done in the manner described in Section 8.7 of the Plan.

  

	 	(f)	All hardship withdrawals shall be paid in an amount determined in the discretion of the Plan Administrator (including amounts representing the amount of federal, state and local
taxes the Participant shall incur as a result of the withdrawal) in accordance with the hardship withdrawal application submitted by the Participant, based on the amount in the Participant’s Account as of the Valuation Date after the Plan
Administrator makes its determination. 

  

	 	(g)	In addition to a Participant’s written request for a hardship withdrawal, the Participant must submit any additional documentation that the Plan Administrator may determine is
necessary to evidence the nature and extent of the immediate and heavy financial need. 

 After receipt by a Participant of a
hardship withdrawal, the Participant’s right to make After-Tax Contributions and Salary-Deferral Contributions (including Catch-Up Contributions) to the Plan and contributions to all plans maintained by an Employer shall be suspended for six
(6) months.

rules established by the Plan Administrator; 

  

	 	(b)	A Participant may make withdrawals of After-Tax Contributions once per calendar quarter, provided, however, that each withdrawal must be made in a minimum amount of at least $500;

  

	 	(c)	All withdrawals shall be made from the Investment Funds in a Participant’s After-Tax Contributions Account as specified by the Participant in instructions sent in accordance

Valuation Date; and 

  

	 	(d)	All withdrawals of amounts in the After-Tax Contributions Account shall be made in either cash or Wyeth Common Stock, if applicable, as elected by the Participant in accordance with

Participant. 

 9.3 Age 59 1/2 Withdrawal 
 Notwithstanding the provisions of Section 8.1 of the Plan, a Participant who has attained age
59 1/2 may make a withdrawal from his Salary-Deferral Account, Rollover Account, and the vested portion of his
Matching Contributions Account once each calendar quarter for any reason without having to demonstrate financial necessity. Such withdrawal shall be made in accordance with instructions sent by the Participant to the Trustee/Recordkeeper in such
manner as prescribed by the Plan Administrator.

 ARTICLE 10 LOANS 
 10.1 Loans 
 A Participant may apply for one loan each calendar quarter in accordance with the
terms prescribed by the Plan Administrator, which shall consistent with the requirements of Section 72(p), 401(k) and 4975(d)(1) of the Code. The following provisions shall apply with respect to Participant loans: 
  

	 	(a)	The minimum loan amount shall be $1,000. The aggregate amount of all such loans to a Participant from this Plan shall not, at the time any such loan is made, exceed the lesser of
(i) $50,000 reduced by the excess (if any) of the highest outstanding balance of loans from the Plan during the one (1) year period ending on the day before the date on which such loan was made, over the outstanding balance of loans from
the Plan on the date on which such loan was made, or (ii) fifty percent (50%) of the vested portion of the Participant’s account balance at the time of the making of such loan. For purposes of this limitation, all loans from all
qualified plans maintained by an Employer or by any entity which is required to be aggregated with an Employer pursuant to Sections 414(b), (c), (m) or (o) must be aggregated. 

  

	 	(b)	A Participant must apply for a loan in accordance with procedures prescribed by the Plan Administrator. A Participant who has applied for a home purchase/construction loan shall be
required to submit an application form and executed copy of a purchase or construction agreement and a written statement certifying that the home shall be used as the Participant’s primary residence. 

  

	 	(c)	For purposes of Section 10.1(a) of the Plan, a Participant’s account balance shall be valued as of a Valuation Date immediately prior to receipt of the Participant’s
loan application. Issuance of the loan shall be as soon as administratively possible in the month in which a loan application is approved. 

  

	 	(d)	The maximum number of loans from the Plan which a Participant may have outstanding at the same time are four general purpose loans and one loan to acquire or construct any dwelling
to be used as the principal residence of the Participant. 

  

	 	(e)	Any loan, by its terms, must be required to be repaid within a whole year term not exceeding five years, unless the loan is used to acquire or construct any dwelling to be used
(within a reasonable time after the loan is made) as the principal residence of the Participant, in which case the whole year term can be from 1 to 15 years. 

  

 47 

			
	Article 10	  	Loans

	 	(f)	The amount of the loan (principal plus interest) must be repaid through periodic payroll deductions in accordance with the Participant’s payroll frequency. The amount of each
periodic payroll deduction shall be based on the Participant’s payroll frequency, the amount of the loan and the term of the loan. The loan shall be amortized in substantially level payments over the term of the loan. All amounts of loan
repayments by the Participant shall be deposited into the Investment Funds elected by the Participant in accordance with Section 7.1 of the Plan in effect at the time the repayments are made. Repayments shall begin with the first paycheck
received in the month following the date the loan check is received by the Participant or as soon as administratively practicable thereafter. Repayments shall be deposited into the Participant’s Account in the following order to the extent that
loan funds were borrowed from the such subaccounts: (i) After-Tax Contributions Account; (ii) the portion of his Rollover account attributable to after-tax contributions; (iii) Matching Contributions Account, (iv) Salary-Deferral
Account; and (v) the portion of his Rollover account attributable to before-tax contributions. 

  

	 	(g)	Upon a Severance From Employment or death, a Participant’s loan is due and payable. In the event that a Participant or his Beneficiary (in the case of the death of the
Participant) does not repay the loan in full, his Account shall be offset by the amount of the outstanding loan and the amount of the outstanding loan shall be treated as taxable income to the Participant. 

  

	 	(h)	The loan funds shall be charged against each of the Participant’s Investment Funds in the Participant’s Account pursuant to the Participant’s instructions in such
manner as prescribed by the Plan Administrator. If instructions are not provided by a Participant, the loan funds shall be charged ratably against each of the Participant’s Investment Funds within his Account. 

  

	 	(i)	Loan funds shall be deducted from the Participant’s Account in the following order: (i) the portion of his Rollover Account attributable to before-tax contributions;
(ii) Salary-Deferral Account (excluding Catch-Up Contributions); (iii) Catch-Up Contributions; (iv) Matching Contributions Account; (v) the portion of his Rollover Account attributable to after-tax contributions; and
(vi) After-Tax Contributions Account. 

  

	 	(j)	The Plan Administrator shall determine the interest rate for loans and which shall be similar to prevailing commercial loan rates. The interest shall be established based on the
Prime Rate plus 1% and shall be stated in the Participant’s loan agreement. Generally, interest begins to accrue on the first day of the month following the date the loan is issued. An interest rate that has been assigned to a loan remains
fixed for the entire term of the loan. 

  

	 	(k)	A Participant may pay a loan in full after he has made six months of repayments. Notwithstanding the foregoing, a Participant shall not be permitted to pay a loan in full for three
months after taking another loan from the Plan. Partial prepayments are not permitted. 

  

 48 

			
	Article 10	  	Loans

	 	(l)	The loan shall be declared in default if the Participant rescinds his payroll authorization deduction. If the amount of the missed repayments (principle and interest) loan is not
repaid in by the end of the quarter following the quarter in which the repayment was due, the outstanding amount of the loan shall be treated as a deemed distribution (except for a Participant who is on Military Leave). 

  

	 	(m)	If a Participant is on an approved unpaid leave of absence at a rate of pay (after applicable employment tax withholdings) that is less than the amount of the installment payments
required under the terms of the loan, repayments shall be suspended until the earlier of (i) the end of the twelve-month period beginning on the date that the Participant commences his leave of absence, or (ii) his return to work. If the
term of the loan expires during the suspension period, the loan shall become immediately due and payable even if the twelve-month suspension period has not expired. If the Participant is still on a leave of absence following the expiration of the
twelve-month suspension period, the loan shall become immediately due and payable. Upon the Participant’s return to employment with an Employer prior to the expiration of the term of the loan and the expiration of the twelve-month period, the
Participant shall repay to the Plan the amount of all missed loan repayments (and interest) that occurred during his leave of absence. If such Participant does not repay the amount of all missed loan repayments (and interest) upon a return to
employment, his loan shall be declared in default. 

  

	 	(n)	A Participant who applies for a loan under this Article Ten of the Plan shall be charged a loan application fee for each loan and an annual loan maintenance fee for each loan in an
amount as determined periodically by the Plan Administrator. 

  

	 	(o)	The loan program under the Plan shall be administered by the Plan Administrator in a uniform and nondiscriminatory manner. 

 The Plan Administrator shall have sole discretion (i) to determine which Participants are entitled to receive a loan, (ii) to determine under
what conditions a loan shall be granted, (iii) to determine what the terms of the loan, promissory note and security agreement are, (iv) to determine when a loan is in default and what course of action to take, and (v) to determine
other questions which arise under this Article Ten of the Plan, provided that such discretion shall be exercised in accordance with the requirements of law and this Article Ten of the Plan.

 ARTICLE 11 LIMITATIONS ON ANNUAL ADDITIONS 
 11.1 Basic Limitation 
 Except
to the extent permitted under Section 4.4 of the Plan and Section 414(v) of the Code, the maximum aggregate Annual Addition that may be contributed or allocated to a Participant’s Account for any Limitation Year shall not exceed the
lesser of: 
  

	 	(a)	$40,000, as adjusted for increases in the cost-of-living under Section 415(d) of the Code; or 

  

	 	(b)	One hundred percent (100%) of the Participant’s Compensation within the meaning of Section 415(c)(3) of the Code for the Limitation Year. 

 The compensation limit referred to in subsection (b) above shall not apply to any contributions for medical benefits after separation from service
(within the meaning of Section 401(h) or Section 419A(f)(2) of the Code), if applicable, which is otherwise treated as an Annual Addition. 
 For purposes of this Article Eleven of the Plan, the term “Annual Addition” shall mean the sum for any Limitation Year of the following amounts: 
  

	 	(i)	Salary-Deferral Contributions; 

  

	 	(ii)	Matching Contributions; 

  

	 	(iii)	After-Tax Contributions; and 

  

	 	(iv)	Forfeitures allocated to the Participant’s Account. 

 For purposes of this Article Eleven of the Plan, the term “Limitation Year” means the calendar year. 
 11.2
Treatment of Similar Plans 
 The limitations described in this Article Eleven of the Plan with respect to any Participant who at
any time has participated in any other defined contribution plan which is 

  

 50 

			
	Article 11	  	Limitations on Annual Additions

 
qualified under Section 401(a) of the Code, or in more than one qualified defined benefit plan, maintained by an Employer or by a corporation which is a
member of a controlled group of corporations (within the meaning of Section 1563(a) (determined without regard to Section 1563(a)(4) and (e)(3)(C), and Section 415(h) of the Code) of which an Employer is a member shall apply as if the
total benefits payable under all such defined benefit plans in which the Participant has been a member were payable from one plan, and as if the total Annual Additions made to all defined contribution plans in which the Participant has been a member
were made to one plan. For purposes of this Article Eleven, the term “Employer” includes any corporation which is a member of a controlled group, as described herein. 
 11.3 Preclusion of Excess Annual Additions 
 The Plan Administrator shall maintain records showing for each month during the Limitation Year contributions credited to a Participant’s Account. If the Plan Administrator determines at any time that no
additional contributions may be credited to a Participant’s Account during a Plan Year without exceeding the limitations prescribed in this Article Eleven of the Plan for the Plan Year, then no further contributions shall be made or credited to
the Participant’s Account during the year. If a portion, but not all, of the contributions which are scheduled to be made and credited to the Participant’s Account during the Plan Year or the remainder of the Plan Year may be made and
credited without exceeding the limitations prescribed hereunder, the Participant’s contributions shall be reduced to such amount which shall cause the limitations to be met. 
 11.4 Disposal of Excess Annual Additions 
 In the event that the limitations with respect to Annual Additions are exceeded with respect to any Participant, and such excess arises as a consequence of a reasonable error in estimating the Participant’s
Compensation, such excess shall be disposed of by returning to the Participant Contributions to his Accounts if any, for the year in which the excess arose, and the earnings thereon, but only to the extent necessary to cause the Annual Additions to
the Participant’s Account to equal, but not exceed, the limitations prescribed hereunder. In the event that after such contributions and earnings are returned there remains an excess, such excess shall be held in a suspense account
and reallocated among the Accounts of all Participants in the Limitation Year succeeding the year in which the excess arose.

accordance with Sections 401(a)(10) and 416 of the Code, if the Plan is or becomes top heavy (within the meaning of Section 416(g) of the Code) in any Plan Year, the provisions of Article Twelve shall supersede any conflicting provisions in the
Plan. 
 12.2 Definitions for Purposes of Article 12 
  

	 	(a)	“Determination Date”. For any Plan Year subsequent to the first Plan Year, the last day of the preceding Plan Year. For the first Plan Year of the Plan, the last
day of that year. 

  

	 	(b)	“Key Employee”. Any Employee or former Employee (including any deceased Employee) who at any time during the Plan Year that includes the determination date was an
officer of an Employer having Annual Compensation greater than $130,000 (as adjusted under Section 416(i)(1) of the Code), a 5-percent owner of the Employer, or a 1-percent owner of the Employer having Annual Compensation of more than $150,000.
For this purpose, Annual Compensation means compensation within the meaning of Section 415(c)(3) of the Code. The determination of who is a Key Employee shall be made in accordance with Section 416(i)(1) of the Code and the applicable
regulations and other guidance of general applicability issued thereunder. 

  

	 	(c)	“Non-Key Employee”. Any Employee who is a Participant and who is not a Key Employee. 

  

	 	(d)	“Permissive Aggregation Group”. The Required Aggregation Group plus any other qualified plans maintained by an Employer, but only if such group would satisfy in the
aggregate the requirements of Sections 401(a)(4) and 410 of the Code. The Plan Administrator shall determine which plan to take into account in determining the Permissive Aggregation Group. 

  

	 	(e)	“Required Aggregation Group”. 

  

	 	(i)	Each qualified plan of an Employer in which at least one Key Employee participates; and 

  

	 	(ii)	Any other qualified plan of an Employer which enables a plan described in (i) to meet the requirements of Sections 401(a)(4) or 410 of the Code. 

 Any terminated plan that covered a Key Employee and was maintained within the five-year period ending on the Determination Date shall also be included in
the Required Aggregation Group. 
  

 52 

			
	Article 12	  	Top Heavy Plan Rules

	 	(f)	“Super Top Heavy Plan”. If for any Plan Year the Plan is considered Top Heavy, the Plan shall be considered “Super-Top-Heavy” if the Top Heavy Ratio
exceeds 90%. 

  

	 	(g)	“Top Heavy Plan”. The Plan is top heavy for a Plan Year if the Top-Heavy ratio as of the Determination Date exceeds sixty percent (60%). 

 

	 	(h)	“Top-Heavy Ratio”. The Plan is top heavy for a Plan Year if the top heavy ratio as of the Determination Date exceeds 60%. The top heavy ratio is a fraction, the
numerator of which is the sum of the present value of the account balances of all Key Employees as of the Determination Date and distributions made within the one year period ending on the Determination Date, and the denominator of which is a
similar sum determined for all Employees. The preceding sentence shall also apply to distributions under a terminated plan which, had it not been terminated, would have been aggregated with the Plan under Section 416(g)(2)(A)(i) of the Code. In
the case of a distribution made for a reason other than separation from service, death, or disability, this provision shall be applied by substituting “5-year period” for “1-year period.” The accrued benefits and accounts of any
individual who has not performed services for an Employer during the 1-year period ending on the determination date shall not be taken into account. The Plan Administrator shall calculate the top heavy ratio without regard to the account balance
attributable to any Non-Key Employee who was formerly a Key Employee. The Plan Administrator shall calculate the top heavy ratio, including the extent to which it must take into account contributions not made as of the Determination Date,
distributions, rollovers and transfers, in accordance with Section 416 of the Code and the Treasury regulations thereunder. 

 If an Employer maintains other qualified plans (including a simplified employee pension plan), this Plan is top heavy only if it is part of the Required Aggregation Group, and the top heavy ratio for both the Required Aggregation Group and
the Permissive Aggregation Group exceeds 60%. The Plan Administrator shall calculate the top heavy ratio in the same manner as required above, taking into account all plans within the aggregation group. The Plan Administrator shall calculate the
present value of accrued benefits and the other amounts the Plan Administrator must take into account under defined benefit plans or simplified employee pension plans included within the group in accordance with the terms of those plans,
Section 416 of the Code and the Treasury regulations thereunder. The Plan Administrator shall calculate the top heavy ratio with reference to the Determination Dates that fall within the same calendar year. 
 12.3 Requirements Applicable if Plan is Top Heavy 
 In the event the Plan is determined to be top heavy for any Plan Year, the following requirements shall be applicable. 

  

 53 

			
	Article 12	  	Top Heavy Plan Rules

 (a) Minimum Allocation 
  

	 	(i)	In the case of a Non-Key Employee who is covered under this Plan but does not participate in any qualified defined benefit plan maintained by Employer, the Minimum Allocation of
contributions plus forfeitures allocated to the Account of each such Non-Key Employee who has not separated from service at the end of a Plan Year in which the Plan is top heavy shall equal the lesser of three percent (3%) of compensation for
such Plan Year or the largest percentage of compensation provided on behalf of any Key Employee for such Plan Year (including any Salary-Deferral Contributions). The Minimum Allocation provided hereunder may not be suspended or forfeited under
Sections 411(a)(3)(B) or 411(a)(3)(D) of the Code. The Minimum Allocation shall be made for a Non-Key Employee for each Plan Year in which the Plan is top heavy, regardless of the Non-Key Employee’s level of compensation, even if he has not
completed twelve months of Continuous Service in such Plan Year or if he has declined to elect to make Salary-Deferral Contributions or After-Tax Contributions, provided, however, in order to receive such Minimum Allocation, the Non-Key Employee
must not have separated from service before the end of the Plan Year for which the Plan is found to be top heavy. 

  

	 	(ii)	A Non-Key Employee who is covered under this Plan and under a qualified defined benefit plan maintained by an Employer shall not be entitled to the Minimum Allocation under this
Plan but shall receive the minimum benefit provided under the terms of the qualified defined benefit plan. 

  

	 	(iii)	Matching Contributions shall be taken into account for purposes of satisfying the minimum contribution requirements of Section 416(c)(2) of the Code and the Plan. The preceding
sentence shall apply with respect to Matching Contributions under the Plan or, if the Plan provides that the minimum contribution requirement shall be met in another plan, such other plan. Matching Contributions that are used to satisfy the minimum
contribution requirements shall be treated as matching contributions for purposes of the actual contribution percentage test and other requirements of Section 401(m) of the Code. 

  

	 	(b)	Top Heavy Vesting Schedule. Unless the Plan’s vesting is more favorable, Non-Key Employee whose employment is terminated after the completion of 2 or more years of
Continuous Service shall be entitled to receive his vested interest in the value of the Matching Contributions credited to his account determined in accordance with the following schedule: 

  

			
	 Years of Continuous Service
	  	 Vested Percentage

	 2
	  	20%
	 3
	  	40%
	 4
	  	60%
	 5
	  	80%
	 6
	  	100%

  

 54 

			
	Article 12	  	Top Heavy Plan Rules

 The vesting schedule under this subsection (b) shall apply to a Non-Key Employee’s interest in
the value of the Matching Contributions credited to his Account under the Plan before or while the Plan is a Top Heavy Plan. A Non-Key Employee is at all times one hundred percent (100%) vested in the full value of his Account attributable to
his Salary-Deferral Contributions and After-Tax Contributions to the Plan. 
  

	 	(c)	Vesting Percentage. In the event that the Plan previously was a Top Heavy Plan but subsequently is not a Top Heavy Plan, the vesting schedule under subsection (b) shall
be changed to the vesting schedule provided under Section 4.4 of the Plan, provided, however, that any Non-Key Employee who has completed at least 3 or more years of Continuous Service and who had at least one Hour of Service while the Plan was
a Top Heavy Plan, shall be entitled to elect, within a reasonable period, which of the above two vesting schedules is applicable to his Account.

time or times as the Plan Administrator in its discretion may determine, through day-to-day contact and evaluation or in any other manner determined to be

	 	(b)	Specific references to pertinent Plan provisions on which the denial was based; 

  

	 	(c)	A description of any additional material and information that is needed to perfect the claim; and 

  

	 	(d)	Advise the claimant that any appeal he wishes to make of the adverse determination must be in writing to the Plan Administrator within sixty (60) days after receipt of the Plan
Administrator’s notice of denial of benefits. The Plan Administrator’s notice must further advise the Claimant that his failure to appeal the action to the Plan Administrator in writing within the sixty (60) day period shall render
the Plan Administrator’s determination final, binding and conclusive; and 

  

	 	(e)	A statement that the Claimant has the right to bring a civil action under Section 502(a) of ERISA following an adverse benefit determination on review.

 Such notice shall be forwarded to the Claimant within 90 days of receipt of the claim; provided, however, that in special

 If the Claimant should file an appeal with the Plan Administrator, or its delegate, he, or his duly
authorized representative, may submit, in writing, whatever issues and comments he or his duly authorized representative feels are pertinent. The Claimant, or his duly authorized representative, may review pertinent Plan documents. The Plan
Administrator shall reexamine all facts to the appeal and make a final determination as to whether the denial of benefits is justified under the circumstances. The Plan Administrator shall advise the Claimant of its decision within sixty
(60) days of receipt of the Claimant’s written request for review, unless special circumstances (such as a hearing) would make the rendering of a decision within the sixty (60) day limit unfeasible, but in no event shall the Plan
Administrator render a decision respecting a denial for a claim for benefits later than one hundred twenty (120) days after its receipt of a request for review. 
 The Claimant shall be given written notice of the decision resulting from such review, which shall include specific reasons for the decision, written in a manner calculated to be understood by the claimant, specific
reference to the pertinent Plan provisions on which the decision is based, a statement that the Claimant is entitled to receive, upon request and free of charge, reasonable access to, and copies, of, all documents, records and other information

whom such responsibilities, obligations or duties have not been allocated or delegated shall be responsible with respect to any action directed, taken or omitted by the Plan fiduciary or individual, corporation or other entity serving in a fiduciary

determination is made.

permitted to contribute an amount equal to the amount of Salary-Deferral Contributions and After-Tax Contributions that such Employee could have made during such absence from employment. Such “make-up” contributions shall be made during
the period that begins with the Employee’s reemployment by an Employer and ends with: 

  

	 	(i)	The expiration of a period of five years; or

For purposes of determining the amount of any make-up contributions under this Article Nineteen of the Plan, and for applying the limits of Article

	Article 19	  	Treatment of Returning Veterans

	 	(b)	If the amount described in subsection (a) above is not reasonably certain, the Participant’s average Covered Compensation from an Employer during the 12-month period
immediately preceding the Qualified Military Service (or, if shorter, the period of employment immediately preceding the Qualified Military Service). Such amount shall be adjusted as necessary to reflect the length of the Participant’s
Qualified Military Service. 

 19.8 Restoration of Matching Contributions 
 If a Returning Veteran contributes “make-up” Salary-Deferral Contributions or After-Tax Contributions pursuant to Section 19.6 of the Plan,
his Employer shall contribute to the Plan on his behalf the related Matching Contributions that it would have contributed under Section 4.6 of the Plan, if such Salary-Deferral Contributions or After-Tax Contributions had been made in the Plan
Year to which they relate. Such Matching Contributions shall not include the earnings that would have accrued on such amount or any forfeitures that would have been allocated to the Returning Veteran’s Account during the period of Qualified
Military Service. 
 19.9 Application of Certain Limitations 
  

	 	(a)	For purposes of applying the limitations of Sections 4.9 and 4.10 of the Plan, any make-up contributions described in Section 19.6 of the Plan, and any related Matching
Contributions described in Section 19.8 of the Plan, shall be treated as contributions for the Plan Year to which they relate, rather than the Plan Year in which they were actually made. 

  

	 	(b)	For purposes of applying the limitations of Section 4.5 of the Plan, any such make-up contributions shall be treated as contributions for the calendar year to which they
relate, rather than the calendar year in which they are actually made. 

  

	 	(c)	For purposes of applying the limitations of applying the limitations of Sections 4.9 and 4.10 of the Plan and Article Eleven of the Plan, any make-up contributions described in
Section 19.6 of the Plan and related Matching Contributions described in Section 19.8 of the Plan shall be disregarded, both for the Plan Year to which the contributions relate, and for the Plan Year in which they are actually made.

 19.10 Suspension of Loan Repayments 
 Notwithstanding any provisions of Article Ten of the Plan to the contrary, if a Participant receives a loan from the Plan and enters into Qualified
Military Service during the term of the loan, a failure to make any required loan repayments during such Qualified Military Service shall not result in a default under Article Ten of the Plan.
