PARSONS EMPLOYEE STOCK OWNERSHIP PLAN

2012 AMENDMENT AND RESTATEMENT

ARTICLE I

GENERAL

1.1 Nature of Plan.

(a) The Plan, formerly known as The Ralph M. Parsons Company Employee Stock Ownership and Retirement Plan, was originally effective as of December 28, 1974. It was amended several times, and on January 1, 1984 it became known as The Parsons Corporation Employee Stock Ownership Plan. The Plan has been amended several times since then, including amendment and restatement in 1989, 1993, 1995, 1997, 1999, 2004 and 2006. Effective as of January 1, 2002, the Plan became known as the Parsons Employee Stock Ownership Plan. The Plan is hereby again amended and republished in its entirety in this 2012 Restatement, generally effective January 1, 2012, except as otherwise provided herein, by applicable law, or by any resolution or other instrument adopting a particular provision. Neither the Plan nor any Predecessor Plan shall be deemed to have terminated as a result of the consolidation of such Predecessor Plan with this Plan. The rights of an Employee terminating employment after December 31, 2011, shall be governed by the terms of the Plan, as in effect on the date of such termination. The rights of an Employee under a Predecessor Plan which is merged with and into this Plan shall be governed by the terms of this Plan, as in effect from time to time on and after the effective date of the merger of such Predecessor Plan with and into the Plan. It is intended, however, that neither this amendment and republication nor any prior amendment and republication will enlarge the rights of Participants in the Plan or a Predecessor Plan, as the case may be, whose employment with a Company terminated prior to January 1, 2012 or the effective date of a merger of a Predecessor Plan with and into the Plan, as the case may be, except as required by applicable law or as expressly provided herein.

(b) The Plan is a combination stock bonus plan (and, for the period set forth in Section 4.1(d), a money purchase pension plan) qualified under Section 401(a) of the Code and consists of two separate and distinct programs which are designed to complement each other. The first program is an employee stock ownership plan, as defined by Section 4975(e)(7) of the Code, designed to invest primarily in Company Stock. The second program is a tax credit employee stock ownership plan, as defined by Sections 41 and 409 of the Code, designed to invest primarily in Company Stock.

(c) The Plan, as amended and republished herein, is designed to enable Eligible Employees indirectly to participate in stock ownership of the Company through participation in the Plan and the Accounts maintained thereunder to the extent that the assets of the Plan and such Accounts are invested in Company Stock and to the extent that distributions with respect to such Stock, whether in Stock or cash, represent the value of such Stock.

(d) The funding policy of the Plan and Trust is as set forth in Article V hereof.

(e) All Trust assets acquired under the Plan as a result of Company and Participant contributions, income and other additions to the Trust shall be administered, distributed, forfeited and otherwise governed by the provisions of the Plan.

(f) The Plan is adopted to reflect certain provisions of the Economic Growth and Tax Relief Reconciliation Act of 2001 (“EGTRRA”) in good faith compliance, and is to be construed in accordance with EGTRRA and guidance issued thereunder.

(g) Effective as of January 1, 2003, certain provisions of the Plan are revised to provide separate contribution allocations for Eligible Employees of the Sponsor and its subsidiaries and Eligible Employees of Parsons E&C Corporation and its subsidiaries.

1.2 Effective Date. The original effective date of this Plan is December 28, 1974, and the general effective date of this 2012 Amendment and Restatement is January 1, 2012 except as otherwise specifically stated.

The Hours of Service credited under this Section shall be credited (1) in the computation period in which the absence begins if the crediting is necessary to prevent a Break in Service in that period, or (2) in all other cases, in the following computation period.

3

Notwithstanding the foregoing, a period of absence from employment shall not be regarded as maternity or paternity leave if the Employee shall fail to comply with a request by the Company to furnish the Plan Administrator such timely information as may be reasonably required to establish that the absence from employment was for a reason set forth above and the number of days for which there was such an absence.

In addition, in the case of an individual who is absent from work during an approved leave of absence granted to an Employee on or after August 5, 1993, pursuant to the Family and Medical Leave Act, the twelve (12) consecutive month period beginning on the first anniversary of the first day of such absence shall not constitute a Break in Service if the Employee returns to work for the Company at the end of such leave of absence.

ARTICLE V

TRUST FUND

5.1 Plan Assets. The Sponsor has entered into the Trust Agreement providing for the establishment of a single Trust to hold the assets of the Plan. All Company contributions shall be paid over to the Trustees and held pursuant to the provisions of the Plan and the Trust Agreement, which, as amended from time to time, shall constitute a part of the Plan. The Board of Directors may at any time, in accordance with the terms of the Trust Agreement, remove an incumbent Trustee and designate a successor Trustee.

5.2 Division of Assets. Assets of the Trust Fund shall be held in separate funds which initially shall consist of the ESOP Fund, PAYSOP Fund and Retirement Fund and thereafter shall consist of such funds as the Committee may establish from time to time. Individual Participant interests in the Trust Fund shall be reflected in the Accounts maintained for each Participant. Notwithstanding the foregoing, the Trust Fund shall be treated as a single trust for purposes of investment and administration, and nothing contained herein shall require a physical segregation of assets for any fund or for any Account maintained under the Plan.

13

5.3 Investment of Trust Fund.

(a) The ESOP Fund shall be invested primarily in Company Stock except for cash or cash equivalent investments for the limited purposes of making Plan distributions to participants or paying Plan administrative expenses, or pending the investment of contributions or other cash receipts in Company Stock. Neither any Company nor the Committee nor any Trustee shall have any responsibility or duty to time any transaction involving Company Stock, in order to anticipate market conditions or changes in stock value, nor shall any such person have any responsibility or duty to sell Company Stock held in the ESOP Fund (or otherwise to provide investment management for Company Stock held in the ESOP Fund) in order to maximize return or minimize loss. The Committee may direct the Trustees to have the ESOP enter into one or more Exempt Loans to finance the acquisition of Company Stock. Company contributions in cash, and other cash received by the Trustees, may be used to acquire shares of Company Stock from Company shareholders or directly from the Company.

(b) The PAYSOP Fund shall be invested primarily in Company Stock except for cash or cash equivalent investments for the limited purpose of making Plan distributions to Participants or paying Plan administrative expenses, or pending the investment of contributions or other cash receipts in Company Stock. Neither any Company nor the Committee nor any Trustee shall have any responsibility or duty to time any transaction involving Company Stock, in order to anticipate market conditions or changes in stock value, nor shall any such person have any responsibility or duty to sell Company Stock held in the PAYSOP Fund (or otherwise to provide investment management for Company Stock held in the PAYSOP Fund) in order to maximize return or minimize loss.

(c) In the case of the De Leuw, Cather Current Service Retirement Plan, amounts invested in ordinary life insurance policies as of September 11, 1984 shall remain so invested in accordance with Article XII of that plan as in effect immediately prior to that date; provided that no application for investment in such policies under said Article XII may be accepted on or after September 11, 1984.

5.4 Exempt Loan. Notwithstanding anything contained herein to the contrary, proceeds of an Exempt Loan shall be used, within a reasonable time after receipt by the Trust, only for the following purposes:

(a) to acquire Company Stock;

(b) to repay the same Exempt Loan; or

(c) to repay any previous Exempt Loan.

An Exempt Loan shall be repaid only from amounts loaned to the Trust and the proceeds of such loans, from Member Company contributions in cash and earnings attributable thereto, from any collateral given for the loan, and from dividends paid on shares of unallocated Company Stock acquired with proceeds of the loan.

No Company Stock acquired with the proceeds of an Exempt Loan may be subject to a put, call, or other option, or buy-sell or similar arrangement while held by the Plan and when distributed by the Plan whether or not the Plan is then an employee stock ownership plan within the meaning of Section 4975(e)(7) of the Code.

14

In addition, and in accordance with Treasury Regulations Sections 54.4975-7 and 54.4975-11, the following provisions shall apply to an Exempt Loan under the Plan:

(i) An Exempt Loan must be for a specific term, and must not be payable at the demand of any person.

(ii) An Exempt Loan must be primarily for the benefit of the Plan participants and their beneficiaries.

(iii) The Plan must not obligate itself to acquire securities from a particular security holder as an indefinite time determined upon the happening of an event, such as the death of the holder.

(iv) The only assets of the Plan that may be given as collateral on an Exempt Loan are qualifying employer securities acquired with the proceeds of the loan and those securities that were used as collateral on a prior Exempt Loan repaid with the proceeds of the current Exempt Loan.

(v) The interest rate of an Exempt Loan must not be in excess of a reasonable rate of interest and should consider the following factors: the amount and duration of the loan, the security and guarantee involved (if any), the credit standing of the Plan and the guarantor (if any), and the interest rate prevailing for comparable loans.

(vi) At the time an Exempt Loan is made, the interest rate for the loan and the price of securities to be acquired with the loan proceeds should not be such that the Plan assets might be drained off.

(vii) No person entitled to payment under an Exempt Loan shall have any rights to assets of the Plan other than collateral given for the loan, contributions (other than contributions of employer securities) made to repay such Exempt Loan, and the earnings attributable to such collateral and the investment of such contributions.

(viii) The payments made with respect to an Exempt Loan by the Plan during a Plan Year must not exceed and amount equal to the sum of such contributions and earnings received during or prior to the year less such payments in prior years. Such contributions and earnings must be accounted for separately in the books of account of the Plan until the loan is repaid.

(ix) In the event of default upon an Exempt Loan, the value of Plan assets transferred in satisfaction of the loan must not exceed the amount of default. If the lender is a Disqualified Person, a loan must provide for a transfer of Plan assets upon default only upon and to the extent of the failure of the Plan to meet the payment schedule of the loan.

(x) In the event that the Plan holds different classes of stock and securities acquired with the proceeds of an Exempt Loan available for distribution consist or more than one class, a distributee must receive substantially the same proportion of each such class of stock.

15

(xi) If a portion of a Participant’s Account is forfeited, qualifying employer securities will be forfeited only after other assets. If interests in more than one class of qualifying employer securities have been allocated to the Participant’s Account, the Participant must be treated as forfeiting the same proportion of each such class of stock.

5.5 Securities Law Limitation. The Committee shall not be required to engage in any transaction, including without limitation, directing the purchase or sale of Company Stock, which it determines in its sole discretion might tend to subject itself, its members, the Plan, any Company, or any Participant to a liability under federal or state securities laws. Further, notwithstanding any provision of the Plan to the contrary, in the absence of an effective registration statement and prospectus or an available exemption from registration, no amount attributable to Employee contributions shall be allocated to the purchase of securities (other than interests or participations in the Trust or Plan) issued by a Company or any company directly or indirectly controlling, controlled by, or under common control with the Company.

5.6 Accounting and Valuations.

(a) The fair value of the assets of the Trust Fund shall be determined as of each Valuation Date, in accordance with generally accepted commercial methods and practices. Valuations of employer securities which are not readily tradable on an established market, will be made by an independent appraiser who meets the requirements similar to the requirements prescribed under Code Section 170(a)(1).

(b) As of each Valuation Date each Participant’s Accounts shall be credited (debited) with the allocable share of the net income (loss) of the portion of the Trust Fund valued as of such Valuation Date. For this purpose the net income (loss) of the Trust Fund shall include any income with respect to securities in the ESOP Suspense Subfund acquired with the proceeds of an Exempt Loan. In determining net income, interest paid under any installment contract for the acquisition of Company Stock by the Trust or on any Exempt Loan shall not be taken into account.

(c) The Committee shall establish accounting procedures for the purpose of making the allocations, valuations and adjustments to Participants’ Accounts provided for in Articles V through XI hereof. From time to time, the Committee may modify its accounting procedures for the purpose of achieving equitable and non-discriminatory allocations among the Accounts of Participants in accordance with the provisions of the Plan.

ARTICLE VI

ALLOCATION OF CONTRIBUTIONS TO THE ESOP FUND

6.1 Allocation of Contributions.

(a) In addition to net income or loss allocated in accordance with Article V and Forfeitures allocated in accordance with Article VIII, the ESOP Account maintained for each Participant will be credited as of each Anniversary Date with his allocable share of (a) Company Stock contributed in kind to the ESOP Fund by Member Companies and (b) contributions under

16

Section 4.1 hereof in other than Company Stock. The allocation of contributions of each Member Company shall be made to the ESOP accounts of those Participants who were Eligible Employees of a Member Company during the Plan Year, and such allocation shall be made in the same proportion that the Compensation for the Plan Year of such Participant while an Eligible Employee of such member Company bears to the total Compensation for the Plan Year of all Participants while Eligible Employees of such Member Company entitled to an allocation under this Section 6.1 for that Plan Year. Each ESOP Account will be debited for its share of cash payments for the acquisition of Company Stock or for repayment of exempt Loans or other debt, including principal and interest, incurred for the acquisition of Company Stock, as Company Stock is allocated to such Account in accordance with Section 6.3 hereof. Allocations of Company Stock shall be expressed in terms of number of whole and fractional interests in shares. A subaccount under each Participant’s ESOP Account shall be maintained to reflect his non-forfeitable interest in any Trust assets (including Company Stock) attributable to dividends on Company Stock allocated to his ESOP Account (other than dividends distributed under the provisions of Section 17.1 hereof). One or more other subaccounts may be established under each Employee’s ESOP Account to differentiate between contributions and earnings thereon and for such other purposes as the Committee deems appropriate.

6.2 Suspense Subfund.

(a) Company Stock acquired by the ESOP Fund through an Exempt Loan shall be added to and maintained in the ESOP Suspense Subfund and shall thereafter be released from the ESOP Suspense Subfund and allocated to ESOP Accounts of Participants as provided in Sections 6.3 and 6.4. The Company Stock acquired with each Exempt Loan shall be accounted for and allocated separately in accordance with the provisions of this Article VI.

6.3 Release from ESOP Suspense Subfund. Company Stock acquired for the ESOP Fund through an Exempt Loan shall be released from the ESOP Suspense Subfund as the Exempt Loan is repaid, in accordance with the provisions of this Section 6.3.

(a) For each Plan Year until the Exempt Loan is fully repaid, the number of shares of Company Stock released from the ESOP Suspense Subfund shall equal the number of unreleased shares immediately before such release for the current Plan Year multiplied by the “Release Fraction.” As used herein, the Release Fraction shall be a fraction the numerator of which is the amount of principal and interest paid on the Exempt Loan for such current Plan Year and the denominator of which is the sum of the numerator plus the principal and interest to be paid on such Exempt Loan for all future years during the duration of the term of such Loan (determined without reference to any possible extensions or renewals thereof). Notwithstanding the foregoing, in the event such Loan shall be repaid with the proceeds of a subsequent Exempt Loan (the “Substitute Loan”), such repayment shall not operate to release all such Company Stock in the ESOP Suspense Subfund, but, rather, such release shall be effected pursuant to the foregoing provisions of this Section 6.3 on the basis of payments of principal and interest on such Substitute Loan.

17

(b) If required by any pledge or similar agreement, then in lieu of applying the provisions of Section 6.3(a) hereof with respect to such loan or Substitute Loan, shares shall be released from the ESOP Suspense Subfund as the principal amount of an Exempt Loan is repaid (and without regard to interest payments), provided the following three conditions are satisfied:

(1) The Exempt Loan must provide for annual payments of principal and interest at a cumulative rate that is not less rapid at any time than level annual payments of such amounts for ten years.

(2) The interest portion of any payment is disregarded only to the extent it would be treated as interest under standard loan amortization tables.

(3) If the Exempt Loan is renewed, extended or refinanced, the sum of the expired duration of the Exempt Loan and the renewal, extension or new Exempt Loan period must not exceed ten years.

(c) If at any time there is more than one Exempt Loan outstanding, then separate accounts may be established under the ESOP Suspense Subfund for each such Loan. Each Exempt Loan for which a separate account is maintained may be treated separately for purposes of the provisions governing the release of shares from the ESOP Suspense Subfund under this Section 6.3 and for purposes of the provisions governing the application of Member Company contributions to repay an Exempt Loan under Section 4.1 hereof.

(d) It is intended that the provisions of this Section 6.3 shall be applied and construed in a manner consistent with the requirements and provisions of Treasury Regulation § 54.4975-7(b)(8), and any successor Regulation thereto. All Company Stock released from the ESOP Suspense Subfund during any Plan Year shall be allocated among Participants as prescribed by Section 6.4 hereof.

6.4 Allocation of Shares Released from ESOP Suspense Subfund.

(a) Shares of Company Stock released from the ESOP Suspense Subfund for a Plan Year in accordance with Section 6.3 hereof shall be held in the ESOP Fund on an unallocated basis until allocated by the Committee as of the Anniversary Date for that Plan Year. The allocation of such shares among the ESOP Accounts of Participants shall be made among the ESOP Accounts of those Participants who were Eligible Employees at any time during the Plan Year and the number of shares allocable to such Participant’s ESOP Account shall be made in the proportion that the Compensation for such Plan Year of each such Participant while an Eligible Employee bears to the total Compensation for the Plan Year of all such Participants while Eligible Employees. All Company Stock in the ESOP Fund, other than Company Stock held in the ESOP Suspense Subfund as of an Anniversary Date, must be allocated to ESOP Accounts as of such Date.

6.5 Stock Dividends, Splits, Recapitalizations, Etc. Any Company Stock received by the Trustees as a result of a stock split, dividend, or as a result of a reorganization or other recapitalization of a Company shall be allocated as of the day on which the Company Stock is received by the Trustees in the same manner as the Company Stock to which it is attributable is then allocated.

18

6.6 Allocation of Amounts Transferred From Defined Benefit Plans. This Section 6.6 shall be effective for periods beginning on and after July 1, 1985. In the case of any amounts contributed under Section 4.1(a) representing amounts transferred from terminated defined benefit pension plans, such amounts shall be either allocated in their entirety in respect of the plan year in which such amounts were transferred to this Plan, subject to the limitations of Article XII hereof, or they shall be allocated to a special suspense fund and allocated from such fund among accounts of participants no less rapidly than ratably over a period not to exceed seven years. Notwithstanding the foregoing, in the year of transfer, the amount allocated shall not be less than the lesser of the maximum allowable under Article XII hereof or one-eighth of the amount attributable to the shares of Company Stock acquired with the transferred amount.

19

(iii) the shares of Company Stock on which any “Synthetic Equity” held by that Participant is based, if this treatment of the Participant’s Synthetic Equity results either in the treatment of any Participant as a Disqualified Person or the treatment of any Fiscal Year as a Non-allocation Year.

Payment of the Participant’s vested Account shall be made following his or her termination of employment as soon as practicable after his or her Normal Retirement Date or Early Retirement Date, but in no event later than the sixtieth (60th) day after the last day of the Plan Year in which the Participant (if he or she were then an Employee) attains his or her Normal Retirement Date, or, if earlier, his or her Early Retirement Date.

(2) Form. The available forms shall depend on the value of the Participant’s vested Account balance.

(i) Vested Account Balance of $20,000 or Less. If the value of the Participant’s vested Account balance is $20,000 or less, then it will be paid as soon as practicable, as the Participant elects, in either

(A) one lump sum payment; or

(B) a direct rollover.

(ii) Vested Account Balance Exceeds $20,000. If the value of the Participant’s vested Account balance exceeds $20,000, then it will be paid as soon as practicable in installments as described in subsection (e).

(b) Permanent Disability.

(1) Timing. A Participant who has suffered a permanent disability while an Employee (even if on an Approved Absence) or after termination of employment, but prior to the distribution of his or her entire vested Account, may be entitled to receive a distribution as soon as practicable after the Committee’s receives proof of such disability.

26

(2) Form. The available forms shall depend on the value of the Participant’s vested Account balance.

(i) Vested Account Balance of $20,000 or Less. If the value of the Participant’s vested Account balance is $20,000 or less, then it will be paid as soon as practicable, as the Participant elects, in either:

(A) one lump sum payment; or

(B) a direct rollover.

(ii) Vested Account Balance Exceeds $20,000. If the value of the Participant’s vested Account balance exceeds $20,000, then it will be paid as soon as practicable in installments as described in subsection (e).

(3) Determination of Disability. A permanent disability, for purposes of this Plan, shall mean the Participant has been determined by the Social Security Administration as eligible for Social Security disability benefits.

(c) Financial Hardship.

(1) Timing. A Participant who has a financial hardship prior to the distribution of his or her entire vested Account may be entitled to receive a distribution as soon as practicable after the Committee’s determination of such hardship. Distribution will be made to a Participant prior to what would otherwise be the Participant’s Normal Retirement Date, or, if applicable, Early Retirement Date, in accordance with this subsection (c).

(2) Form. The available forms shall depend on the value of the Participant’s vested Account balance.

(i) Vested Account Balance of $20,000 or Less. If the value of the Participant’s vested Account balance is $20,000 or less, then it will be paid as soon as practicable, as the Participant elects, in one lump sum payment.

(ii) Vested Account Balance Exceeds $20,000. If the value of the Participant’s vested Account balance exceeds $20,000, then it will be paid as soon as practicable in installments as described in subsection (e).

(3) Determination of Financial Hardship. The Committee shall determine in its sole discretion whether a genuine financial hardship exists, but in so doing shall not find a genuine financial hardship to exist unless there exists probative evidence of severe want or deprivation which cannot reasonably be expected to be relieved by other resources reasonably available to the Participant. The Committee shall prescribe such rules as it deems appropriate in making determinations as to the existence of a hardship. In no event, however, shall the Committee find that sources reasonably available to relieve a hardship include a Participant’s

27

primary residence. Further, the Committee shall in every case find that sources reasonably available to a Participant for the relief of a hardship include business ventures and other investments or property (other than a primary residence), if any, that are reasonably liquid and susceptible to reasonably rapid sale.

(4) Notwithstanding subsection (c)(2), a Participant receiving installment distributions may halt such distributions by written notice given to the Trustee at least 30 days in advance of the first scheduled payment as of which distributions should cease. A Participant may, by a showing of hardship, resume such distributions subject to subsection (c)(3).

(d) Conflicts of Interest. If a Participant who has terminated employment with all Companies but has not received his or her complete distribution from the Plan becomes subject to a conflict of interest by reason of his or her beneficial interest in Company Stock held hereunder, his or her Account consisting of Company Stock shall, upon satisfactory proof to the Committee of such conflict, be converted into cash and shall be distributed in accordance with the terms of this Plan governing distribution of ESOP Accounts as described in subsection (a)(2).

(e) Installments. Installment distributions shall be made subject to the following rules:

(1) Installment payments can only be made if the Participant’s vested Account balance is at least $20,001.

(A) If the Participant’s vested Account balance is from $20,001 to $40,000, then it will be paid in a series of installments over two years or, if shorter, the life expectancy of the Participant and his or her Spouse, if any.

(B) If the Participant’s vested Account balance exceeds $40,000, then it will be paid in a series of installments over either three or five years, as the Participant elects, but in no case shall the number of yearly installments exceed the life expectancy of the Participant and his or her Spouse, if any.

(2) The first installment in a series shall be determined by multiplying the vested value of the Participant’s Account by a fraction the numerator of which is one and the denominator of which is the number of scheduled installments in the series. The next installment is the remaining Account balance for the year multiplied by a fraction the numerator of which is one and the denominator of which is the denominator for the previous year reduced by one. Except if subsection (c)(2)(4) is applicable, successive installments in a series, if any, are determined the same way.

(3) Any remaining undistributed balance of the Participant’s Account shall be non-forfeitable, held in the Participant’s Account and will continue to share in the net income of the Trust including any appreciation or depreciation in the value of Company Stock.

(f) Small Account Balances. Notwithstanding any other provision in this Plan to the contrary, a Participant who has a termination of employment (regardless of whether such termination is prior to the Participants Normal or Early Retirement Date) shall automatically receive an immediate distribution without his or her consent if the value of his or her vested Account balance is $5,000 or less.

28

(1) Vested Account Balance of $1,000 or Less. If the Participant’s vested Account balance is $1,000 or less, distribution will be made as soon as administratively feasible in one lump sum payment unless it is at least $200 and the Participant timely elects to directly roll it over to an eligible retirement plan.

(2) Vested Account Value of $1,001 to $5,000. If the Participant’s vested Account balance exceeds $1,000 but does not exceed $5,000 and the Participant does not timely elect a lump sum distribution or a direct rollover, then it will be directly rolled over to an individual retirement account designated by the Committee.

9.3 Change of Method of Distribution. If any amount is being paid to a Participant in installments pursuant to Section 9.2 hereof, the Committee may, at the election of the Participant or Beneficiary, upon the occurrence of such Participants Early or Normal Retirement Date, permanent disability or death, pay the balance then credited to the Participant or Beneficiary in a lump sum in accordance with the provisions hereof providing for the payment of the balance of an amount in a lump sum.

9.4 Form of Distribution of Capital Accumulation. Distribution of a Participant’s Capital Accumulation shall be made in cash; provided, however, the Company may require that distributions of that portion of such Participant’s Capital Accumulation invested in Company Stock be made in kind. Any distributions made in Company Stock shall be subject to an immediate automatic repurchase right in favor of the Company. The amount payable to a Participant pursuant to the automatic repurchase right set forth in the preceding sentence shall be paid by the Company either (a) in a single lump sum within 30 days following the date of the distribution made in Company Stock or (b) in substantially equal periodic payments (not less frequently than annually) over a period beginning not later than 30 days following the date of the distribution made in Company Stock and not exceeding 5 years; provided, that the Company provides adequate security and pays reasonable interest on any unpaid amounts following the commencement of such payments. In addition, at the election of the Participant, any life insurance policies held in the Plan may be distributed as an in-kind distribution. In accordance with Code Sections 79, 83, and 401 and regulations promulgated thereunder, effective February 13, 2004, any transfer of a life insurance contract from an employer to an employee must be taxed at its full fair market value. Such fair market value will be determined at the time contract (sic) is distributed and using the formula(s) defined in code Section 402.

Notwithstanding the foregoing, no distribution may be made in Company Stock to any Participant who is a nonresident alien or whose spouse is a nonresident alien for U.S. federal income tax purposes.

9.5 Benefit Commencement Deadline. Notwithstanding the provisions of Articles IX, X and XI of the Plan regarding distributions of Participants’ Capital Accumulations, the following additional rules shall apply to all such distributions.

29

(a) In no event shall any benefits under this Plan, including benefits upon retirement, termination of employment, or permanent disability (as determined under Section 11.2), be paid to a Participant prior to the “Consent Date” (as defined herein) unless the Participant consents in writing to the payment of such benefits prior to said Consent Date. As used herein, the term “Consent Date” shall mean the Participant’s 65th birthday. Notwithstanding the foregoing, the provisions of this Paragraph shall not apply (1) following the Participant’s death, or (2) with respect to a lump-sum distribution of a Participant’s Capital Accumulation if the total amount of the Capital Accumulation does not exceed $5,000.

Effective as of March 28, 2005, in the event of a mandatory distribution greater than $1,000 in accordance with the provisions of this Section 9.5(a), if the Participant does not elect to have such distribution paid directly to an eligible retirement plan specified by the Participant in a direct rollover or to receive the distribution directly in accordance with Section 9.2 and 9.4 hereof, then the Plan Administrator will pay the distribution in a direct rollover to an individual retirement plan designated by the Plan Administrator.

(b) Unless the Participant elects otherwise pursuant to Paragraph (a) above, distributions of the vested portion a Participants Capital Accumulation shall commence no later than the 60th day after the close of the Plan Year in which the latest of the following events occurs: (1) the Participant’s Normal Retirement Age; (2) the tenth anniversary of the year in which the Participant commenced participation in the Plan; or 3) the Participant’s termination of employment with the Company.

(c) (1) Notwithstanding the foregoing, with respect to distributions under the Plan made on or after December 31, 2001 for calendar years beginning on or after January 1, 2001, the Plan will apply the minimum distribution requirements of Code Section 401(a)(9) in accordance with the regulations under Section 401(a)(9) that were proposed on January 17, 2001 (the “2001 Proposed Regulations”). If the total amount of required minimum distributions made to a participant for 2001 prior to December 31, 2001 are equal to or greater than the amount of required minimum distributions determined under the 2001 Proposed Regulations, then no additional distributions are required for such participant for 2001 on or after such date. If the total amount of required minimum distributions made to a participant for 2001 prior to December 31, 2001 are less than the amount determined under the 2001 Proposed Regulations, then the amount of required minimum distributions for 2001 on or after such date will be determined so that the total amount of required minimum distributions for 2001 is the amount determined under the 2001 Proposed Regulations. This paragraph shall continue in effect until the last calendar year beginning before the effective date of the final regulations under Code Section 401(a)(9) or such other date as may be published by the Internal Revenue Service.

(2) Notwithstanding Section 9.5(c)(1) or any other provision of the Plan to the contrary but subject to Section 9.5(d), below, the following provisions shall apply with respect to determining minimum distributions for calendar years beginning with the 2003 calendar year:

(i) The Participant’s entire interest will be distributed, or begin to be distributed, to the Participant no later than the Participant’s required beginning date.

30

(ii) If the Participant dies before distributions begin, the Participant’s entire interest will be distributed, or begin to be distributed, no later than as follows:

(A) If the Participant’s surviving spouse is the participant’s sole designated beneficiary, distributions to the surviving spouse will 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.

(B) If the Participant’s surviving spouse is not the Participant’s sole designated beneficiary, distributions to the designated beneficiary will begin by December 31 of the calendar year immediately following the calendar year in which the Participant died.

(C) 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 will be distributed by December 31 of the calendar year containing the fifth anniversary of the Participant’s death.

(D) 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 provision shall apply as if the surviving spouse were the Participant.

For purposes of this Section 9.5(c)(2), distributions are considered to begin on the Participant’s required beginning date (or, if Section 9.5(c)(2)(ii)(D) applies, the date distributions are required to begin to the surviving spouse). If annuity payments 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 Section 9.5(c)(2)(ii)(D)), the date distributions are considered to begin is the date distributions actually commence.

(iii) 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 will be made in accordance herewith. If the Participant’s interest is distributed in the form of an annuity purchased from an insurance company, distributions thereunder will be made in accordance with the requirements of Code Section 401(a)(9) and the Treasury regulations.

(iv) If the Participant’s interest is paid in the form of annuity distributions under the Plan, payments under the annuity will satisfy the following requirements:

(A) The annuity distributions will be paid in periodic payments made at intervals not longer than one year;

31

(B) The distribution period will be over a life (or lives) or over a period certain not longer than the period described in Section 9.5(c)(2)(ii);

(C) Once payments have begun over a period certain, the period certain will not be changed even if the period certain is shorter than the maximum permitted;

(D) Payments will either be non-increasing or increase only as follows:

(1) By an annual percentage increase that does not exceed the annual percentage increase in a cost-of-living index that is based on prices of all items and issued by the Bureau of Labor Statistics;

(2) To the extent of the reduction in the amount of the Participant’s payments to provide for a survivor benefit upon death, but only if the beneficiary whose life was being used to determine the distribution period described above dies or is no longer the Participant’s beneficiary pursuant to a qualified domestic relations order within the meaning of Code Section 414(p);

(3) To provide cash refunds of employee contributions upon the participant’s death; or

(4) To pay increased benefits that result from a plan amendment.

(v) The amount that must be distributed on or before the Participant’s required beginning date (or, if the Participant dies before distributions begin, the date distributions are required to begin above) is the payment that is required for one payment interval. The second payment need not be made until the end of the next payment interval even if that payment interval ends in the next calendar year. Payment intervals are the periods for which payments are received. All of the Participant’s benefit accruals as of the last day of the first distribution calendar year will be included in the calculation of the amount of the annuity payments for payment intervals ending on or after the Participant’s required beginning date.

(vi) Any additional benefits accruing to the Participant in a calendar year after the first distribution calendar year will be distributed beginning with the first payment interval ending in the calendar year immediately following the calendar year in which such amount accrues.

(vii) If the Participant’s interest is being distributed in the form of a joint and survivor annuity for the joint lives of the Participant and a non-spouse beneficiary, annuity payments to be made on or after the Participant’s required beginning date to the designated beneficiary after the Participant’s death must not at any time exceed the applicable percentage of the annuity payment for such period that would have

32

been payable to the participant using the table set forth in Q&A-2 of section 1.401(a)(9)-6T of the Treasury regulations. If the form of distribution combines a joint and survivor annuity for the joint lives of the Participant and a non-spouse beneficiary and a period certain annuity, the requirement in the preceding sentence will apply to annuity payments to be made to the designated beneficiary after the expiration of the period certain.

(viii) Unless the Participant’s spouse is the sole designated beneficiary and the form of distribution is a period certain and no life annuity, the period certain for an annuity distribution commencing during the Participant’s lifetime may not exceed the applicable distribution period for the participant under the Uniform Lifetime Table set forth in section 1.401(a)(9)-9 of the Treasury regulations for the calendar year that contains the Annuity Starting Date. If the Annuity Starting Date precedes the year in which the Participant reaches age 70, the applicable distribution period for the Participant is the distribution period for age 70 under the Uniform Lifetime Table set forth in section 1.401(a)(9)-9 of the Treasury regulations plus the excess of 70 over the age of the Participant as of the Participant’s birthday in the year that contains the Annuity Starting Date. If the Participant’s spouse is the Participant’s sole designated beneficiary and the form of distribution is a period certain and no life annuity, the period certain may not exceed the longer of the Participant’s applicable distribution period, as determined under this Section, or the joint life and last survivor expectancy of the Participant and the Participant’s spouse as determined under the Joint and Last Survivor Table set forth in section 1.401(a)(9)-9 of the Treasury regulations, using the Participant’s and spouse’s attained ages as of the Participant’s and spouse’s birthdays in the calendar year that contains the Annuity Starting Date.

(ix) If the Participant dies before the date distribution of his or her interest begins and there is a designated beneficiary, the Participant’s entire interest will be distributed, beginning no later than the time described herein, over the life of the designated beneficiary or over a period certain not exceeding:

(A) Unless the annuity starting date is before the first distribution calendar year, the life expectancy of the designated beneficiary determined using the beneficiary’s age as of the beneficiary’s birthday in the calendar year immediately following the calendar year of the Participant’s death; or

(B) If the annuity starting date is before the first distribution calendar year, the life expectancy of the designated beneficiary determined using the beneficiary’s age as of the beneficiary’s birthday in the calendar year that contains the annuity starting date.

(x) 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 will be completed by December 31 of the calendar year containing the fifth anniversary of the Participant’s death.

33

(xi) If the Participant dies before the date distribution of his or her interest begins, the Participant’s surviving spouse is the participant’s sole designated beneficiary, and the surviving spouse dies before distributions to the surviving spouse begin, this Section 9.5(c)(2) will apply as if the surviving spouse were the Participant, except that the time by which distributions must begin will be determined without regard to Section 9.5(c)(2)(ii)(D).

(xii) For purposes of this Section 9.5(c)(2), the following terms have the following meanings:

(A) “Designated beneficiary” means the individual who is designated as the beneficiary under the Plan and is the designated beneficiary under Code Section 401(a)(9) and section 1.401(a)(9)-1, Q&A-4, of the Treasury regulations.

(B) “Distribution calendar year” means 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 this Section 9.5(c)(2).

(C) “Life expectancy” means life expectancy as computed by use of the Single Life Table in section 1.401(a)(9)-9 of the Treasury Regulations.

(D) “Required beginning date” means April 1 of the calendar year following the calendar year in which the Participant (i) attains age 70¹⁄₂ or (ii) retires, whichever is later; except that, in the case of a Participant who is a five percent owner (as defined in Code Section 416) of the Company with respect to the calendar year in which he attains age 70¹⁄₂, required beginning date means April 1 following the calendar year in which the Participant attains age 70¹⁄₂.

(d) With respect to the portion of a Participant’s Capital Accumulation consisting of Company Stock allocated to his ESOP account, where such stock was acquired by the Plan after December 31, 1986 (“Post-1986 Amounts”), the following rules shall apply:

(1) If the Participant so elects, Post-1986 Amounts shall commence to be distributed to the Participant not later than 1 year after the close of the Plan Year-

(i) in which the Participant terminates employment with the Company by reason of attainment of Normal Retirement age, permanent disability (as determined under Section 11.2), or death, or

(ii) which is the 5th Plan Year following the Plan Year in which the Participant otherwise separates from service, except that this clause shall not apply if the Participant is reemployed by the Company before distribution is required to begin under this clause.

34

(2) For the purposes of this paragraph (d), the Post-1986 Amounts allocated to a Participant’s ESOP Account shall not include any Company Stock acquired with the proceeds of an Exempt Loan until the close of the Plan Year in which such loan is repaid in full.

(3) Unless the Participant elects a less rapid distribution period, the distribution upon a Participant’s Post-1986 Amounts shall be in substantially equal periodic payments (not less frequently than annually) over a period not longer than the greater of:

(i) 5 years, or

(ii) in the case of a Participant with Post-1986 Amounts in excess of $500,000, 5 years plus 1 additional year (but not more than 5 additional years) for each $100,000 or fraction thereof by which such amount exceeds $500,000.

(4) The dollar amounts specified in subparagraph (3) above shall be adjusted at the same time and in the same manner by the Secretary of the Treasury as under Code Section 415(d).

(5) This paragraph (d) is intended to accelerate the date of distribution of Post-1986 Amounts pursuant to Code Section 409(o). Therefore, if such amounts should be distributed sooner under any other provision of this Plan, such provision overrides this paragraph (d).

(e) If it is not administratively practical to calculate and commence payments by the latest date specified in the rules of Paragraphs (a), (b), (c) and (d) above because the amount of the Participant’s benefit cannot be calculated, or because the Committee is unable to locate the Participant after making reasonable efforts to do so, the payment shall be made as soon as is administratively possible (but not more than 60 days) after the Participant can be located and the amount of the distributable benefit can be ascertained.

(f) If any payee under the Plan is a minor or if the Committee reasonably believes that any payee is legally incapable of giving a valid receipt and discharge for any payment due him, the Committee may have such payment, or any part thereof, made to the person (or persons or institution) whom it reasonably believes is caring for or supporting such payee, or, if applicable, to any duly appointed guardian or committee or other authorized representative of such payee. Any such payment shall be a payment for the account of such payee and shall, to the extent thereof, be a complete discharge of any liability under the Plan to such payee.

(g) Notwithstanding anything in this Section 9.5 to the contrary, unless the Participant subject to the required minimum distribution rules of this Section 9.5 elects to receive such distributions, effective as of January 1, 2009, the Code Section 401(a)(9) requirements of Section 9.5 will not apply for the 2009 calendar year, and furthermore, the five-year period described in Code Section 401(a)(9)(B)(ii) will be determined without regard to calendar year 2009.

35

9.6 Application for Determination of Benefits.

(a) The Committee may require any person claiming benefits under the Plan or any authorized representative of such a person, to submit an application therefor, together with such documents and information as the Committee or its delegate may require.

(b) Within 90 days following receipt of a properly completed application, the Committee or its delegate reviewing the claim shall furnish the claimant with written notice of the decision rendered with respect to the application. If the Committee or its delegate determines that an extension of up to an additional 90 days for processing the application is required, written notice of the extension shall be furnished to the claimant prior to the termination of the initial 90-day period. The extension notice shall indicate the special circumstances requiring an extension of time and the date by which the Committee or its delegate expects to render a determination.

The appeal shall be made in writing within 65 days after the date of notice of the decision with respect to the application. If the application has neither been approved nor denied within the 90-day period provided in Section 9.6(b) hereof, then the appeal shall be made within 65 days after the expiration of the 90-day period. In making his appeal, the claimant may request that his application be given full and fair review by the Committee. The claimant may review, upon request and free of charge, all documents, records, and other information relevant to the claimant’s claim for benefits, and may submit issues , documents, records and comments in writing and all such information will be taken into account by the Committee. The decision of the Committee shall be made promptly, and not later than 60 days after the Committee’s receipt of a request for review, unless special circumstances require an extension of time for processing, in which case a decision shall be rendered as soon as possible, but not later than 120 days after receipt of a request for review and written notice of the extension shall be provided to the claimant prior to expiration of the initial 60-day period indicating the special circumstances requiring an extension of time and the date by which the Committee expects to render the determination on review. The decision on review shall be in writing and shall include specific reasons for the decision, written in a manner calculated to be understood by the claimant with specific references to the pertinent Plan provisions upon which the decision is based, and 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 relevant to the claimant’s claim for benefits.

36

(d) Notwithstanding the foregoing, with regard to a claim that involves a determination of a permanent disability, the Committee or its delegate reviewing the claim shall furnish the claimant with written notice of the decision rendered with respect to the application within 45 days following receipt of an application. If the Committee or its delegate determines that an extension of up to an additional 30 days for processing such an application is required, written notice of the extension shall be furnished to the claimant prior to the termination of the initial 45-day period. The extension notice shall indicate the special circumstances requiring an extension of time and the date by which the Committee or its delegate expects to render a determination. If prior to the end of a the first 30-day extension period, the Committee or its delegate determines that a decision cannot be rendered within that extension period, the period for making the determination may be extended for up to an additional 30 days, provide that the Committee or its delegate notifies the claimant prior to the expiration of the first 30-day extension period that indicates the special circumstances requiring an extension of time and the date by which the Committee or its delegate expects to render a determination. Any notice of extension shall specifically explain the standards on which entitlement to a benefit is based, the unresolved issues that prevent a decision on the claim, and the additional information needed to resolve those issues, and the claimant shall be afforded at least 45 days within which to provide the specified information. With regard to a claim that involves a determination of a permanent disability, any written notice of denial shall contain the following, in addition to the items set forth in Section 9.6(c):

(2) If the adverse benefit determination is based on a medical necessity or experimental treatment or similar exclusion or limit, either an explanation of the scientific or clinical judgment for the determination, applying the terms of the plan to the claimant’s medical circumstances, or a statement that such explanation will be provided free of charge upon request;

37

(3) Either the specific internal rules, guidelines, protocols, standards or other similar criteria of the Plan relied upon in making the adverse determination or, alternatively, a statement that such rules, guidelines, protocols, standards or other similar criteria of the Plan do not exist; and

(4) 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 relevant to the claimant’s claim for benefits.

(e) Notwithstanding the foregoing, with regard to an appeal of a benefit determination that involves a determination of a permanent disability, before the Committee can issue an adverse benefit determination on review, the Committee shall also provide the claimant, free of charge, with (1) any new or additional evidence considered, relied upon, or generated by Committee in connection with the claim; and (2) any new or additional rationale on which an adverse benefit determination is to be made. In addition, the Committee’s decision shall be made within a reasonable period of time, but not later than 45 days (rather than 60 days) after the Committee’s receipt of a request for review. In addition to the information set forth in Section 9.6(c), any notice of adverse determination on review of a claim involves a determination of a permanent disability shall also include the information set forth in Section 9.6(d)(l) through 9.6(d)(3).

9.7 Forfeiture on Failure to Locate Participant or Beneficiary. In the event that a Participant or Beneficiary or other recipient of benefits cannot be located with reasonable efforts within five (5) years of the date when benefits are first eligible to be paid under the Plan, the amount representing the benefits which such person would otherwise have been entitled to receive shall be forfeited and re-allocated to the Plan Accounts of all remaining Participants in the manner provided in Section 8.5. Notwithstanding the foregoing or anything to the contrary in this Plan, if any Participant, Beneficiary or other recipient of benefits shall make an appropriate claim for benefits subsequent to the forfeiture referred to in the preceding sentence, then such person shall he entitled to payment of such amount which was forfeited.

9.8 Special Rule For Money Purchase Plans. Notwithstanding any other provision of this Plan, if the Capital Accumulation in a Participant’s Retirement Account and Employee Contribution Account has an aggregate value in excess of $5,000 and is attributable to a Predecessor Plan that, prior to its consolidation with the Plan, was a money purchase pension plan, such Capital Accumulation shall be distributable in accordance with this Section 9.8.

(a) Unless a form of benefit prescribed by Section 9.2 hereof is selected pursuant to a Qualified Election within the 180-day period ending on the Participant’s Benefit Commencement Date, a Participant’s Capital Accumulation subject to this Section 9.8 will be paid in the form of a Qualified Joint and Survivor Annuity.

(b) For purposes of this Section 9.8, “Qualified Joint and Survivor Annuity” shall mean an annuity for the life of the Participant with a survivor annuity for the life of the Spouse which is not less than 50 percent and not more than 100 percent of the amount of the annuity which is payable during the joint lives of the Participant and the Spouse and which is the amount of benefit which can be purchased with the participant’s Capital Accumulation subject to this Section 9.8.

(c) For purposes of this Section 9.8, “Qualified Election” shall mean a waiver of a Qualified Joint and Survivor Annuity. The waiver must be in writing, must designate that benefits will be paid in an optional form or designate a beneficiary in addition to or other than the Participant’s Spouse which may not be changed without spousal consent (unless the original consent (i) acknowledges the right to limit consent to a specific Beneficiary, and (ii) expressly permits designations by the Participant without the requirement of any further consent by the Spouse, and must be consented to by the Participant’s Spouse. The Spouse’s consent to a waiver must be witnessed by a Plan representative or notary public. Notwithstanding this consent requirement, if the Participant establishes to the satisfaction of a Plan representative that such written consent may not be obtained because there is no Spouse or the Spouse cannot be located, a waiver will be deemed a Qualified Election. Any consent necessary under this provision will be valid only with respect to the Spouse who signs the consent, or in the event of a deemed Qualified Election, the designated Spouse. Additionally, a revocation of a prior waiver may be made by a Participant without the consent of the Spouse at any time before the commencement of benefits. The number of revocations shall not be limited.

(d) For purpose of this Section 9.8, “Spouse” or “Surviving Spouse” shall mean the spouse or surviving spouse of the Participant, provided that a former spouse will be treated as the Spouse or Surviving Spouse to the extent provided under a qualified domestic relations order as described in Section 4l4(p) of the Code.

(e) The Committee shall provide each Participant within 30 days of such Participant’s Benefit Commencement Date, a written explanation of: (i) the terms and conditions of a Qualified Joint and Survivor Annuity; (ii) the Participant’s right to make and the effect of an election to waive the Qualified Joint and Survivor Annuity form of benefit; (iii) the rights of a Participant’s Spouse; (iv) the right to make and the effect of a revocation of a previous election to waive the Qualified Joint and Survivor Annuity; provided, however, that a Participant may waive (with applicable spousal consent) the requirement that the written explanation be provided within 30 days of the Participant’s Benefit Commencement Date, if the Participant’s distribution commences more than 7 days after such explanation is provided.

(f) For the purpose of this Section 9.8, “Benefit Commencement Date” shall mean (i) the first day of the first period for which an amount is payable as an annuity, however, the first day of the first period for which a benefit is to be received by reason of a disability shall be treated as the Benefit Commencement Date only if such benefit is not an auxiliary benefit within the meaning of Code Section 417(f)(2)(B); or (ii) in the case of a benefit not payable in the form of an annuity, the first day on which all events have occurred which entitle the Participant to such benefit.

9.9 Direct Transfers

(a) This Section applies to distributions made on or after January 1, 1993. Notwithstanding any provisions of the Plan to the contrary that would otherwise limit a distributee’s election under this Section, a 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.

(b) Definitions.

(1) Eligible Rollover Distributions. An eligible rollover distribution is any distribution of all or any portion of the balance to the credit of the distributee, except that an eligible rollover distribution does not include:

(i) any distribution that is one of a series of substantially equal periodic payments (not less frequently than annually) made for the life (or life expectancy) of the distributee or the joint lives (or joint life expectancies) of the distributee and the distributee’s designated beneficiary, or for a specified period of ten years or more;

(ii) any distribution to the extent such distribution is required under Code Section 401(a)(9); and

(iii) and the portion of any distribution that is not includable in gross income (determined without regard to the exclusion for net realized appreciation with respect to employer securities and any amount that is distributed on account of hardship).

If all or any portion of a Plan distribution during the 2009 calendar year would have been treated as a required minimum distribution under Code Section 401(a)(9), but for the application of Plan Section 9.5(g), then such distribution shall not be treated as an eligible rollover distribution for purposes of this Section 9.9.

(2) Eligible Retirement Plan: An eligible retirement plan must accept the distributee’s eligible rollover distribution and must be an individual retirement account described in Code Section 408(a), an individual retirement annuity described in Code Section 408(b), an annuity plan described in Code Section 403(a), an annuity contract described in Code Section 403(b), an eligible plan under Code Section 457(b) that is maintained by a state, political subdivision of a state, or any agency or instrumentality of a state or political subdivision of a state and which agrees to separately account for amounts transferred into such plan from this Plan, a qualified trust described in Code Section 401(a) or a Roth IRA described in Section 408A(b) of the Code. However, in the case of an eligible rollover distribution to either the surviving spouse or a non-spouse beneficiary, an eligible retirement plan is an individual retirement account or individual retirement annuity.

40

(3) Distributee: A distributee includes an employee or former employee. In addition, the employee’s or former employee’s Surviving Spouse, non-spouse beneficiary, and the employee’s or former employee’s Spouse or former Spouse who is the alternate payee under a Qualified Domestic Relations Order, as defined in Code Section 414(p), are distributees with regard to interests of the Spouse or former Spouse.

(4) Direct Rollover: A direct rollover is a payment by the Plan to the eligible retirement plan specified by the distributee.

(c) For purposes of the direct rollover provisions in this Section 9.9 of the Plan, a portion of a distribution shall not fail to be an eligible rollover distribution merely because the portion consists of after-tax employee contributions which are not included in gross income. However, such portion may be transferred only to an individual retirement account or annuity described in Section 408(a) or 408(b) of the Code, or to a qualified defined contribution plan described in section 401(a) or 403(a) of the Code that agrees to separately account for amounts so transferred, including separately accounting for the portion of such distribution which is includible in gross income and the portion of such distribution which is not so includible.

DEATH BENEFITS

10.1 Methods of Distribution. Upon the death of a Participant prior to his termination of employment with all Companies, the entire interest of the decedent in the Trust Fund shall be distributed as soon as practicable after the decedent’s death, but in no event later than five years after the date of such death. The amount distributed shall be based on the value of the decedent’s interest on the valuation date coinciding with or immediately preceding the date of distribution. If the beneficiary is a spouse and such spouse dies before payments begin, subsequent distributions shall be made as if the spouse had been the Participant. Notwithstanding the foregoing provisions of this Section 10.1, a Surviving Spouse (as defined in Section 10.7) shall be entitled to receive the death benefit to which that spouse is entitled pursuant to a survivor annuity described in Section 10.7 hereof or pursuant to a Qualified Joint and Survivor Annuity described in Section 9.8 hereof. Such survivor annuity shall commence as soon as possible following the Participant’s death but not later than one year after the Participant’s death, or the date on which the Participant would have attained age 70-1/2, whichever is later.

10.2 Death After Termination of Employment. Upon the death of a Participant after retirement, permanent disability retirement or other severance, but prior to the distribution of his entire Capital Accumulation, the Committee shall direct the Trustees to make distribution of any vested balance remaining in the decedent’s Accounts as soon as practicable after the decedent’s death but in no event later than 5 years after the date of such death. The amount distributed shall be based on the value of the decedent’s interest on the Valuation Date coinciding with or immediately preceding the date of distribution. If distribution has commenced prior to the date of the Participant’s death, the remaining balance of the Participant’s Capital Accumulation shall be distributed at least as rapidly as under the method of distribution in effect as of the date of the Participant’s death. If the Beneficiary is a Spouse and such Spouse dies before payments begin,

41

subsequent distribution shall be made as if the Spouse had been the Participant. Notwithstanding the foregoing provisions of this Section 10.2, a Surviving Spouse (as defined in Section 10.7 hereof) shall be entitled to receive the death benefit to which that Spouse is entitled pursuant to the survivor annuity described in Section 10.7 hereof or pursuant to a qualified Joint and Survivor Annuity described in Section 9.8 hereof. Such Survivor Annuity shall commence as soon as possible following the Participant’s death but not later than 1 year after the Participant’s death, or the date on which the Participant would have attained age 70-1/2, whichever is later.

10.3 Designation of Beneficiary. At any time, and from time to time, each Participant shall have the unrestricted right to designate the Beneficiary or Beneficiaries to receive the portion of his death benefit or to revoke any such designation. Each such designation shall be evidenced by a written instrument filed with the Committee, signed by the Participant. If the deceased Participant shall have failed to designate a Beneficiary, or if the Committee shall be unable to locate the designated Beneficiary after reasonable efforts have been made, or if such Beneficiary shall be deceased, distribution shall be made by payment of the deceased Participant’s entire interest in the Trust Fund to his personal representative in a lump sum within one (1) year after his death. In the event the deceased Participant is not a resident of California at the date of his death, the Committee, in its discretion, may require the establishment of ancillary administration in California. If the Committee cannot locate a qualified personal representative of the deceased Participant, or if administration of the deceased Participant’s estate is not otherwise required, the Committee, in its discretion, may pay the deceased Participant’s interest in the Trust Fund to his heirs at law (determined in accordance with the laws of the State of California as they existed at the date of the Participant’s death).

10.4 Incapacity of Participant or Beneficiary. If any payee under the Plan is a minor, or if the Committee reasonably believes that any payee is legally incapable of giving a valid receipt and discharge for any payment due him, the Committee may have such payment, or any part thereof, made to the person (or persons or institution) whom it reasonably believes is caring for or supporting such payee, unless it has received due notice of claim therefor from a duly appointed guardian or committee of such payee. Any such payment shall be a payment for the account of such payee and shall, to the extent thereof, be a complete discharge of any liability under the Plan to such payee.

10.5 Additional Documents. The Committee or Trustees, or both, may require the execution and delivery of such documents, papers and receipts as the Committee or Trustees may determine necessary or appropriate in order to establish the fact of death of the deceased Participant and of the right and identity of any Beneficiary or other person or persons claiming any benefits under this Plan.

10.6 Special Rule. With respect to Participants who performed one or more Hours of Service on or after August 23, 1984 and die after such date, any designation of a Beneficiary other than the surviving spouse at the date of the Participant’s death for payment of the Participant’s death benefit under the Plan shall not be valid unless such surviving spouse has consented to the payment of such death benefit to such Beneficiary in form and manner satisfactory to the Plan Administrator and in compliance with the requirements of Section 417 of the Code.

42

10.7 Special Rule for Money Purchase Plans. Notwithstanding any other provisions of this Plan, in the event of a Participant’s death prior to his Benefit Commencement Date (as defined in Section 9.8(f)) with respect to his Capital Accumulation in his Retirement Account and Employee Contribution Account the aggregate value of which exceeds $5,000 and is attributable to a Predecessor Plan that, prior to its consolidation with this Plan, was a money purchase pension plan, such Capital Accumulation Account shall be distributable in accordance with this Section 10.7.

(a) The Participant’s Capital Accumulation shall be paid to the Participant’s Surviving Spouse in the form of an annuity for the life of the Surviving Spouse (“QPSA”), unless the Surviving Spouse selects a payment form prescribed in Section 9.2 hereof or the Participant within the Election Period waives the QPSA and designates another Beneficiary, pursuant to a Qualified Election, to receive his Capital Accumulation subject to this Section 10.7, as provided in Section 10.1 hereof. The Surviving Spouse shall be entitled to direct the commencement of payments under the QPSA within a reasonable time after the Participant’s death but shall not be required to commence such payments prior to the date the Participant would have attained Normal Retirement Date.

(b) For purposes of this Section 10.7, “Election Period” shall mean the period which begins on the first day of the Plan Year in which the Participant attains age 35 and ends on the date of the Participant s death. If a Participant separates from service prior to the first day of the Plan Year in which age 35 is attained, the election period shall begin on the date of separation.

(c) For purposes of this Section 10.7, “Qualified Election” shall mean the Participant’s waiver of the QPSA and the designation of a Beneficiary other than a Spouse (including any class of Beneficiaries or contingent Beneficiaries). The designation must be in writing, must designate a Beneficiary other than the Participant’s Spouse which may not be changed (unless back to the QPSA) without Spousal consent (unless the original consent of the Spouse (i) acknowledges the right to limit consent to a specific Beneficiary and (ii) expressly permits designations by the Participant without the requirement of any further consent by the Spouse), and must be consented to by the Spouse. The Spouse’s consent must acknowledge the effect of the election and be witnessed by a Plan representative or notary public. A Qualified Election shall be valid only if made after the Participant has received a written explanation of the QPSA during the applicable period in accordance with Section 417(a)(3) of the Code and the regulations thereunder. Notwithstanding this consent requirement, if the Participant establishes to the satisfaction of a Plan representative that such written consent may not be obtained because there is no Spouse or the Spouse cannot be located, a selection shall be deemed a Qualified Election. Any consent necessary under this Section 10.7 will be valid only with respect to the Spouse who signs the consent, or in the event of a deemed Qualified Election, the designated Spouse. Additionally, a revocation of a prior waiver of the QPSA may be made by a Participant without the consent of the Spouse at any time before the Participant’s death. The number of revocations shall not be limited.

(d) For purposes of this Section 10.7, “Spouse” or “Surviving Spouse” shall mean the spouse or surviving spouse of the Participant, provided that a former spouse will be treated as the Spouse or Surviving Spouse to the extent provided under a Qualified Domestic Relations Order described in Section 414(p) of the Code.

ARTICLE XI

DISABILITY BENEFITS

11.1 Method of Distribution. In the event a Member Company shall determine that a Participant has suffered a permanent disability while an Employee or on an Approved Absence, the Committee shall direct the Trustee to make a distribution of such Participant’s Capital Accumulation as soon as practicable after the Committee’s determination of such disability in the manner prescribed in Section 9.2 as though such Participant had attained his Normal or Early Retirement Date. The amount distributed shall be based on the value of the Participant’s Accounts on the Valuation Date coinciding with or immediately preceding the date of distribution.

11.2 Determination of Disability. A permanent disability, for purposes of this Plan, shall mean the Participant has been determined by the Social Security Administration as eligible for Social Security disability benefits.

11.3 Disability After Termination of Employment. In the event that a Member Company shall determine that a Participant has suffered a permanent disability after termination of employment, but prior to the distribution of his entire Capital Accumulation, the Committee shall direct the Trustees to make distribution of his Capital Accumulation as though the Participant had attained his Normal or Early Retirement Date as provided in Section 9.2; except that the Participant’s vested interest in his accounts shall not increase by reason of such disability. The amount distributed shall be based on the value of the Participant’s accounts on the Valuation Date coinciding with or immediately preceding the date of distribution. The provisions of Section 9.8 shall apply to any distribution made pursuant to this Section 11.3.

12.2 Annual Additions. For purposes of Section 12.1, the term “Annual Additions” shall mean with respect to a Participant, for any Limitation Year with respect to this Plan and each other defined contribution plan, within the meaning of Code Section 415(k), maintained by a Company (“Defined Contribution Plan”), the sum of the amounts determined under Sections 12.2(a), (b), (c) and (d) hereof:

Notwithstanding any provision in the Plan, in the case of shares of Company Stock released from the ESOP Suspense Subfund and allocated to the ESOP Account of a Participant for a particular Plan Year, the Company shall determine for such year that an Annual Addition will be calculated on the basis of the fair market value of shares of Company Stock so released and allocated if the Annual Addition as so calculated is lower than the Annual Addition calculated on the basis of Member Company contributions.

(b) All amounts contributed by the Participant.

(c) Forfeitures allocated to such Participant. For purposes of this Section 12.2, forfeitures shall not include Forfeitures of Company Stock acquired through the ESOP Fund with the proceeds of an Exempt Loan, provided that no more than one-third of the Member Company contributions to the ESOP Fund deductible under Section 404(a)(9) of the Code for a Limitation Year are allocated to Highly Compensated Employees (as that term is defined in Section 414(q) of the Code).

12.3 Other Defined Contribution Plans. If any Company maintains any other Defined Contribution Plan then each Participant’s Annual Additions under this Plan shall be aggregated with the Participant’s Annual Additions under this Plan for the purposes of applying the limitations of Section 12.1.

46

12.4 Defined Benefit Plans. For Plan Years commencing prior to January 1, 2000, if a Participant in this Plan has also been a participant in a defined benefit plan (as defined in Section 415(k) of the Code) maintained by any Company (“Defined Benefit Plan”), then in addition to the limitation contained in Section 2.1 hereof, the sum of the “Defined Benefit Fraction,” as defined in Section 12.4(a) hereof, and the “Defined Contribution Fraction,” as defined in Section 12.4(b) hereof, for any Limitation Year shall not exceed 1.0.

(a) “Defined Benefit Fraction” shall mean a fraction, the numerator of which is the total projected benefit of a Participant under all Defined Benefit Plans expressed as either an annual straight life annuity or a qualified joint and survivor annuity providing the maximum permissible survivor benefit (determined as of the close of the Limitation Year), and the denominator of which is the lesser of (1) the maximum dollar amount otherwise allowable for such Limitation Year under Section 415(b)(1)(A) of the Code times 1.25 or (2) the percentage of compensation limit under Section 415(b)(1)(B) of the Code for such Limitation Year times 1.4.

(b) “Defined Contribution Fraction” shall mean a fraction, the numerator of which is the sum of the Participant’s Annual Additions to this Plan and all other Defined Contribution Plans as of the end of a Limitation Year, and the denominator of which is the sum, determined for such Limitation Year and each prior Limitation Year of the Participant’s service with a Company of the lesser of (1) the maximum dollar Annual Addition under Section 415(c)(1)(A) (determined without regard to Section 415(c)(6) of the Code) of the Code which could have been made for the Limitation Year times 1.25 or (2) the amount determined under the percentage of compensation limit for such Limitation Year under Section 415(c)(1)(B) of the Code times 1.4. In computing the Defined Contribution Fraction under this Section 12.4(b) with respect to any Limitation Year ending after December 31, 1982, the special transition rule provided in Section 415(e)(6) of the Code shall be applicable.

12.5 Adjustments for Excess Annual Additions. To the extent that the Annual Additions on behalf of any Participant in a Limitation Year to this Plan and all other Defined Contribution Plans exceed the limitations set forth in Sections 12.1 through 12.3 hereof, then excess Annual Additions shall be eliminated in the following sequence:

(a) The Participant’s voluntary contributions, if any, to this Plan, and all other Defined Contribution Plans, including any earnings thereon, shall be returned to the Participant to the extent of any excess Annual Additions.

(b) If excess Annual Additions remain after the application of Section 12.5(a) hereof, then there shall be reduced, to the extent of such remaining excess Annual Additions, Company Contributions allocated to the Participant’s Accounts under Article VI hereof, including any earnings thereon.

(c) If excess Annual Additions remain after the application of Section 12.5(b) hereof, the amounts allocated to a Participant’s PAYSOP Account under Section 7.2 shall be reduced to the extent of such remaining excess Annual Additions. If after the application of this Section 12.5(c), Company Stock remains unallocated for a Plan Year, such Company Stock must be held in a special suspense account under the PAYSOP Fund. Such Company Stock shall be allocated to PAYSOP Accounts in subsequent Plan Years in accordance with applicable Treasury Regulations.

47

(d) The amount by which an allocation is reduced under Section 12.5(b) shall be treated as a Forfeiture under Section 8.5 hereof and reallocated proportionately to the appropriate Accounts of other Participants receiving allocations for the Limitation Year up to the limits set forth in Sections 12.1 through 12.3 hereof on Annual Additions to such other Participant’s Accounts. To the extent a contribution cannot be allocated to other Participant’s Accounts, it may not be made.

12.6 Adjustment for Excessive Combined Plan Fraction. For Plan Years commencing prior to January 1, 2000, if the Annual Additions on behalf of a Participant in a Limitation Year to the Plan and all other Defined Contribution Plans would cause the sum of the Defined Contribution Fraction and Defined Benefit Fraction to exceed 1.0 as determined under Section 12.4 hereof, then, Section 12.5 hereof shall be applied to reduce Annual Additions. If application of Section 12.5 is insufficient to reduce the Fraction to 1.0, then each Participant’s benefit accruals under the Defined Benefit Plans during the Limitation Year shall, if possible, be reduced to the extent necessary to reduce the sum of the Fractions to 1.0.

12.7 Affiliated Company. Notwithstanding any other provision of the Plan, for purposes of Article XII the status of a Company as an Affiliated Company shall be determined in accordance with the special rules set forth in Section 415(h) of the Code.

12.8 Compensation. For the limited purpose of applying the provisions of this Article XII, “Compensation” means all wages, salaries, and fees for professional services and other amounts received for personal services actually rendered in the course of employment with the Company or an Affiliated Company (including, but not limited to commissions paid salesmen, compensation for services on the basis of a percentage of profits, commissions on insurance premiums, tips and bonuses). Effective for Plan Years commencing on and after January 1, 1998, “Compensation” for purposes of this Article XII shall include any elective deferral (as defined in Code Section 402(g)(3)) and any amount which is contributed or deferred by the Member Company at the election of the Employee and which is not includible in the gross income of the Employee by reason of Sections 125 or 457 of the Code or is a qualified transportation fringe benefit described in Code Section 132(f)(4), but shall exclude the following:

(a) Contributions to a plan of deferred compensation which are not includible in the Employee’s gross income for the taxable year in which contributed, or contributions under a simplified employee pension plan to the extent such contributions are deductible by the Employee, or any distributions from a plan of deferred compensation;

(b) Amounts realized from the exercise of a non-qualified stock option, or when restricted stock (or property) held by the Employee either becomes freely transferable or is no longer subject to a substantial risk of forfeiture;

(c) Amounts realized from the sale, exchange or other disposition of stock acquired under a qualified stock option;

48

(d) Other amounts which received special tax benefits, or contributions made by an Affiliate (whether or not under a salary reduction agreement) towards the purchase of an annuity described in Code Section 403(b) (whether or not the amounts are actually excludable from the gross income of the Employee);

(e) Any contribution for medical benefits (within the meaning of Section 419(f)(2) of the Code) after termination of employment which is otherwise treated as an Annual Addition; and

(f) Any amount otherwise treated as an Annual Addition under Section 415(1) of the Code.

(a) No amendment shall have the effect of reducing any Participant’s vested interest in the Trust Fund.

(b) No amendment, except to the extent and under the circumstances permitted from time to time by the law governing the requirements applicable to qualified plans within the meaning of Section 401 of the Code (or any successor statute), shall have the effect of diverting any part of the Plan assets for any purpose other than the exclusive benefit of Participants or their Beneficiaries and defraying reasonable expenses of administering the Plan.

When the Plan transfers assets and liabilities of a Participant it may, but need not, transfer all of a Participant’s Account.

ARTICLE XV

54

15.2 Termination.

ARTICLE XVI

TOP-HEAVY PROVISIONS

16.1 Application of Top-Heavy Rules. Notwithstanding anything in this Plan to the contrary, if the Plan is classified as a “Top-Heavy Plan” under Section 416(g) of the Code for any Plan Year beginning after December 31, 1983, then the Plan shall meet the following requirements of this Article XVI.

16.2 Minimum Contribution Requirement.

(a) The Plan shall provide a minimum contribution allocation for each Employee who is not classified as a “Key Employee” and who is an Employee on the last day of the Plan Year without regard to the amount of service performed by the Employee during such Plan Year. Such minimum contribution allocation for such Plan Year for each Employee who is not a Key Employee shall be an amount equal to at least three percent (3%) of such Employee’s Compensation for such Plan Year (excluding amounts deferred under a cash or deferred arrangement under Section 401(k) of the Code and any employer contributions taken into account under Section 401(k)(3) or 401(m) of the Code). The Employee’s minimum contribution allocation under this Section 16.2 shall be calculated without regard to any Social Security benefits payable to the Employee.

(b) Notwithstanding the foregoing, if the contribution allocation for each Employee who is a Key Employee for the Plan Year is less than three percent (3%) of Compensation (including amounts deferred under a cash or deferred arrangement under Section 401(k) of the Code and any employer contributions taken into account under Section 401(k)(3) or 401(m) of the Code), the maximum contribution allocation for each Employee who is not a Key Employee shall be limited to not more than the highest contribution allocation for any Employee who is a Key Employee. The foregoing contribution allocation shall be determined by dividing the highest amount contributed for an Employee who is a Key Employee by his Compensation, not in excess of the dollar limitation in effect for the year under Section 401(a)(17) of the Code.

16.3 Minimum Vesting Requirement. An Employee shall be fully vested in his Accounts, within the meaning of Section 411 of the Code and Section 203 of ERISA, upon his completion of three Years of Cumulative Service. In the event the Plan is a top-heavy plan for any Plan Year, then for subsequent Plan Years in which the Plan is not a top-heavy plan the preceding sentence shall not apply and the vesting schedule under Section 8.3 shall apply. The non-forfeitable percentage of any Employee as of the effective date of a change in vesting

55

schedule, however, may not be less than the non-forfeitable percentage of such Employee immediately prior to such date and any Employee with three or more Years of Cumulative Service must be permitted to elect to have his non-forfeitable percentage computed under the vesting schedule in effect prior to such change. The election may be made during a period which begins no later than the effective date of the change and ends no earlier than 60 days after the later of the changes effective date or the date Employees are issued written notice of the change. No opportunity to make an election need be afforded to any Employee whose non-forfeitable percentage, under the vesting schedule as changed, cannot at any time be less than such non-forfeitable percentage without regard to such change.

16.4 Reserved.

16.5 Impact on Maximum Allocations. For any Plan Year in which the Plan is a Top-Heavy Plan, Section 12.4 shall be applied by substituting the number 1.0 for the number “1.25” wherever it appears therein, unless the requirements of both Sections 16.5(a) and 16.5(b) are satisfied.

(a) The requirements of this Section 16.5(a) are satisfied if the Plan would not be a Top-Heavy Plan when Sections 16.6(a)(1) and 16.6(d) are applied by substituting “ninety percent (90%)” for “sixty percent (60%)” each place such term appears therein.

(b) The requirements of this Section 16.5(b) are satisfied when Section 16.2 is applied by substituting “four percent (4%)” for “three percent (3%)” each place such term appears therein.

16.6 Definitions.

(a) Top-Heavy Plan. The Plan shall be a “Top-Heavy Plan” for a Plan Year if, as of the Valuation Date last preceding or coinciding with the Determination Date:

(1) Except as provided in Section 16.6(a)(2), the aggregate value of the Account balances under the Plan for all Employees who are Key Employees exceeds sixty percent (60%) of the aggregate value of the Account balances under the Plan for all Employees; or

(2) The Plan is part of an “Aggregation Group” and such group is a “Top-Heavy Group.” If the Plan is part of an Aggregation Group and such group is not a “Top-Heavy Group” then the Group shall not be considered top-heavy. Notwithstanding the foregoing, the Plan shall not be considered top-heavy if it would not be considered top-heavy under Section 416 of the Code.

(3) For purposes of this Paragraph (a), the following definitions shall apply. The term “Determination Date” shall mean, with respect to any Plan Year, the last day of the preceding Plan Year, or in the case of the first Plan Year, the first day of such year. The term “Valuation Date” shall mean the date on which assets are valued for the purpose of determining Account balances.

56

(b) Key Employee. A “Key Employee” is any Employee (including a beneficiary of such Employee) who, subject to Section 416(i) of the Code or the Regulations thereunder, at any time during the Plan Year or any of the four preceding Plan Years is:

(1) An officer of a Company earning more than 50 percent times the dollar limitation in effect under Section 4l5(b)(1)(A) of the Code (but in no event shall more than 50 Employees or, if less, the greater of three or ten Percent of all Employees be taken into account under this Section 16.6(b)(1) as Key Employees);

(2) One of the ten (10) Employees earning more than the dollar limitation in effect under Section 415(c)(1)(A) of the Code and owning (or considered as owning within the meaning of Section 318 of the Code) the largest interests in a Member Company; provided, that, if two employees have the same interest in a Member Company, the Employee having greater Compensation will be deemed to have the greater interest;

(3) A person owning (or considered as owning within the meaning of Section 318 of the Code) more than five percent (5%) of the outstanding stock of a Member Company or stock possessing more than five percent (5%) of the total combined voting power of all stock of a Member Company; or

(4) A person who has an annual compensation from a Company of more than one hundred fifty thousand dollars ($150,000) and who would be described in Section 16.6(b)(3) hereof if one percent (1%) were substituted for five percent (5%).

(5) Notwithstanding the foregoing, for Plan Years beginning after December 31, 2001, a Key Employee means 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 the employer having annual Compensation greater than $130,000 (as adjusted under section 416(i)(1) of the Code for Plan Years beginning after December 31, 2002), a five percent (5%) owner of the Company, or a one percent (1%) owner of the Company 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 will 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) Aggregation Group. “Aggregation Group” means a group of plans maintained by one or more Companies determined according to the following rules:

(1) The Aggregation Group shall include all such plans which are required to be included in the Aggregation Group as follows:

(i) Each plan of a Company in which a Key Employee is a Participant; and

(ii) Each other plan of a Company which enables any Plan described in (i), above, to meet the requirements of Section 401(a)(4) or 410 of the Code.

57

(2) If the Committee or its delegate elects, the Aggregation Group may include any other plan maintained by one or more Companies, provided the Aggregation Group satisfies the requirements of Sections 401(a)(4) and 410 of the Code.

(d) Top-Heavy Group. The Aggregation Group shall be a “Top-Heavy Group” for a Plan Year if, as of the last day of the preceding Plan Year, the sum of (1) the present value of the cumulative accrued benefits for Key Employees under any defined benefits plans included in the Aggregation Group, and (2) the Account balances of Key Employees under any defined contribution plans included in the Aggregation Group exceeds sixty percent (60%) of the sum of the total cumulative accrued benefits and Account balances for all participants under all the plans in the Aggregation Group. If the Aggregation Group is a Top-Heavy Group, each plan required to be included in the Aggregation Group is a Top-Heavy Plan. However, no plan included in the Aggregation Group at the election of the Committee shall be subject to the top-heavy rules of this Article XVI solely on account of such election.

(e) Compensation. For purposes of this Article XVI, the term Compensation has the meaning given such term by Code Section 415(c)(3).

(f) Non-Key Employee. A “Non-Key Employee” is any Employee (including a former Employee) who is not a Key Employee.

16.7 Special Rules.

(a) For purposes of determining the present value of the cumulative accrued benefit of any Employee, or the amount of the Account balance of any Employee, such present value or amount shall be increased for distributions made to the Participant during the one (1) year period ending on the Determination Date. However, if a distribution is made for a reason other than severance from service, death or disability, a five (5) year look back period shall be exchanged for the one (1) year period in the preceding sentence. The rules above shall also apply to distributions under a terminated plan that, if it had not been terminated, would have been required to be included in a Aggregation Group. Also, any rollover contribution or similar transfer initiated by the Employee and made after December 31, 1983 to a plan shall be taken into account with respect to the transferee plan for purposes of determining whether such plan is a Top-Heavy Plan (or whether any Aggregation Group which includes such plan is a Top-Heavy Group) in accordance with Code Section 416(g)(4)(A).

(b) If any individual is a Non-Key Employee with respect to any plan for any plan year, but the individual was a Key Employee with respect to the plan for any prior plan year, any accrued benefit for the individual (and the Account balance of the individual) shall not be taken into account for purposes of this Article XVI.

(c) If any individual has not performed services for the Company or an Affiliated Company (other than benefits under the Plan) at any time during the one (1) year period ending on the Determination Date, any accrued benefit for such individual (and the account balance of the individual) shall not be taken into account for purposes of this Article XVI.

58

(d) In applying the foregoing provision of this Section, the accrued benefit of a Non-Key Employee shall be determined (i) under the method, if any, which is used for accrual purposes under all plans of the Company and any Affiliated Company, or (ii) if there is no such uniform method, as if such benefit accrued not more rapidly than the slowest accrual rate permitted under Code Section 414(b)(1)(C).

ARTICLE XVII

MISCELLANEOUS

17.1 Dividends. Cash dividends on shares of Company Stock allocated to Participants’ Accounts may be paid currently to Participants, as determined by the Committee, in its sole discretion. Such dividends shall be paid in cash directly by a Company, or may be distributed by the Trustees after receipt from the Company within 180 days after the end of the Plan Year of receipt by the Trustees. Dividends on shares of unallocated stock, including shares of stock acquired with the proceeds of an Exempt Loan and held in the ESOP Suspense Fund shall either be applied to payment of the Exempt Loan or held in the ESOP Suspense Fund.

17.2 Annual Statement. As soon as possible after each Anniversary Date each Participant will receive a written statement showing:

(a) the balance in each of his Accounts as of the preceding Anniversary Date;

(b) the amount of Company contributions (and Forfeitures) allocated to his Accounts for that Plan Year;

(c) the adjustments to his Accounts to reflect his share of dividends and the net income (or loss) of the Trust for that Plan Year; and

(d) the new balances in each of his Accounts, including the number of shares of Company Stock, as of that Anniversary Date.

17.3 No Right to Employment Hereunder. The adoption and maintenance of this Plan shall not be deemed to constitute a contract of employment or otherwise between any Company and any Employee or Participant, or to be consideration for, or an inducement or condition of, any such employment. Nothing contained herein shall be deemed to give to any person the right to be retained in the service of any Member Company or to interfere with the right of the Member Company to discharge, with or without cause, any Employee or Participant at any time.

17.4 Limitation on Company Liability. Any benefits payable under this Plan shall be paid or provided for solely from the Trust fund and no Company assumes any liability or responsibility therefor. The Companies obligations hereunder are limited solely to the making of contributions to the Trust Fund as provided for in this Plan. No Company shall be responsible for any decision, act or omission of the Trustees or the Committee or an Operating Committee, or shall be responsible for the application of any monies or other property paid or delivered to the Trustees.

59

17.5 Exclusive Benefit. Except to the extent and under the circumstances permitted from time to time by the law governing the requirements applicable to qualified plans within the meaning of Section 401 of the Code (or any successor provision), none of the assets held by the Trustees under this Plan shall ever revert to any Company or otherwise be diverted to purposes other than the exclusive benefit of the Plan Participants or their Beneficiaries and defraying reasonable expenses of administering the Plan. Notwithstanding the foregoing:

(a) Any contribution made by a Company by a mistake of fact may be returned to such Company within one year after such contribution is made.

(b) If a contribution by a Company is conditioned on qualification of the Plan under Section 401 of the Code, and the Plan does not qualify, then such contributions may be returned to such Company within one year after the denial of qualification.

(c) If a contribution by a Company is conditioned upon its deductibility under Section 404 of the Code, then, to the extent the deduction is disallowed, such contribution may be returned to such Company within one year after the disallowance of the deduction.

17.6 No Alienation. Subject to the exceptions set forth pursuant to Code Section 401(a)(13), no economic interest, expectancy, benefit, payment, claim or right of any Participant or Beneficiary hereunder shall be subject to any claims of any creditor of any Participant or Beneficiary nor to attachment, garnishment or other legal process initiated by, or to the lien of any bankruptcy trustee or receiver appointed for the estate of any such Participant or Beneficiary, nor shall any such Participant or Beneficiary have any right to alienate, commute, pledge, encumber or assign any such economic interest, expectancy, benefit, payment, claim or right, contingent or otherwise. In the event any person attempts to take any action contrary to this Section 17.6, such action shall be null and void and of no effect, and each Company, the Committee, the Operating Committee, and the Trustees shall disregard such action and shall not in any manner be bound thereby and shall suffer no liability on account of their disregard thereof.

The preceding provisions of this Section 17.6 shall also apply to the creation, assignment, or recognition of a right to any benefit payable with respect to a Participant pursuant to a domestic relations order, unless such order is determined to be a domestic relations order, as defined in Section 414(p) of the Code, or any domestic relations order entered before January 1, 1986 if payments pursuant to such order commenced as of such date.

17.7 PAYSOP Account Assets Not Subject To Company Withdrawal. If any amount of the employee stock ownership credit allowed under Section 41 of the Code resulting from Company contributions to this Plan is redetermined in accordance with the provisions of the Code, the amounts transferred to the PAYSOP Fund shall remain in such Fund or in PAYSOP Accounts, as the case may be, and shall continue to be allocated and held in accordance with the Plan.

17.8 Rights Pursuant to USERRA. To the extent required by applicable federal law, including the Uniformed Services Employment and Reemployment Rights Act of 1994, if a uniformed services Employee returns to employment after cumulative military service of up to 5

60

years and qualifies for reemployment under such applicable federal law, then the returning Employee (to the extent he would otherwise qualify for participation hereunder) shall have the right to receive Company Contributions, set forth in Article IV, that the Employee would have otherwise received absent this military service. The Company must make these Company Contributions within the later of either:

(i) 90 days of the Employee’s return to employment, or

(ii) when such contributions are normally made for the Plan Year in which the Employee performs the military service.

Contributions will be based on the Compensation the Employee would have earned if he or she had not entered the military, or, if that determination is not reasonably certain, the Compensation earned during the 12-month period prior to entering the military. Upon re-employment, the Plan will credit a uniformed services Employee with the Hours of Service he or she missed while on that leave (for up to five years, as set forth above). The Employee may not share in any forfeiture allocations occurring during his or her period of military service.

17.9 Redetermination of Tax Credits. If the amount of any employee stock ownership credit claimed by the Member Companies under Code Section 41 for a prior fiscal year is reduced because of a determination that becomes final during the current fiscal year, and such Companies transferred amounts to the Trust Fund that were taken into account for purposes of the employee stock ownership credit under Code Section 41 for that prior fiscal year, then the Member Companies may at their election do either of the following:

(a) Reduce the amount they are required to transfer to the PAYSOP Fund for the current fiscal year or any succeeding fiscal year by an amount equal to such reduction in the credit or increase in tax which is attributable to Company contributions to the Plan; or

(b) Deduct such portion subject to the limitations of Code Section 404(i)(2) of the Code.

17.10 Addresses. Each Participant not actively employed by a Company and each Beneficiary entitled to receive benefits under the Plan must file with the Committee, in writing, his current post office address. Any communication, statement or notice addressed to such a person at his latest post office address as filed with the Committee will, on deposit in United States mail with postage prepaid, be binding upon such person for all purposes, and neither the trustees nor the Committee nor any Operating Committee nor any Company shall be obliged to search for or ascertain the whereabouts of any such person.

17.11 Data. Each person entitled to benefits under the Plan must furnish to the Committee or any Operating Committee such documents, evidence, or information as it considers necessary or desirable for the purpose of administering the Plan, or to protect the Companies or the trustees; and it shall be a condition of the Plan that each person must furnish such information promptly and sign such documents before any benefits become payable under the Plan.

61

17.12 Gender and Number. Masculine gender shall include the feminine, and the singular shall include the plural unless the context clearly indicates otherwise.
