INTRODUCTION

1.1      The Plan . The following provisions constitute the Caterpillar 401(k) Savings Plan (the “Plan”), for the benefit of certain employees of Caterpillar Inc. and certain employees of its subsidiaries and affiliates that adopt the Plan.

1.2      Type of Plan . For purposes of Section 401(a)(27) of the Code, the Plan is designated as a profit-sharing plan that includes a cash or deferred arrangement qualified under Section 401(k) of the Code and an “employee stock ownership plan” within the meaning of Section 4975(e)(7) of the Code.

1.3      Plan Objectives . The Plan is maintained by the Sponsor in order to enable eligible employees of the Sponsor and Affiliates that adopt the Plan to save for their retirement on a tax-favored basis, to provide a source of retirement income for such employees, to stimulate interest and initiative and increase efficiency among such employees, and to share with them the economic benefits produced by their efforts.

1.4      Exclusive Benefit . The Plan is for the exclusive benefit of the Participants and their Beneficiaries. No portion of the funds contributed to the Plan shall ever revert to or be applied for the benefit of the Employers, except as specifically permitted herein.

1.5      Funding . In order to fund the benefits provided under the Plan, the Sponsor has established the Trust pursuant to the Trust Agreement. All benefits under the Plan shall be provided exclusively by distributions from the Trust. The Benefit Funds Committee shall have the authority to appoint, remove and replace the Trustee of the Trust at any time, in its discretion, or to establish additional Trusts to fund benefits under the Plan.

1.6      Sponsor and Employers . The sponsor of the Plan is Caterpillar Inc., a Delaware corporation. With the approval of the Sponsor, the Plan may be adopted for the benefit of its Employees by any Affiliate. The Sponsor and Affiliates that adopt the Plan are referred to in the Plan individually, as an “Employer,” and collectively, as the “Employers.”

1.7      Effective Date . The original effective date of the Plan was January 1, 2011. Except as otherwise specifically required with respect to particular provisions of the Plan or as required by ERISA or the Code, the provisions of this amended and restated Plan document shall be effective as of January 1, 2017. The Plan is separate and distinct from the Caterpillar 401(k) Retirement Plan, formerly known as the Caterpillar 401(k) Plan, which became effective on January 1, 2003. Some Participants in the Plan were participants, or may have account balances, in the Caterpillar 401(k) Retirement Plan. Any such Participant’s Account Balance under this Plan shall be solely governed under the terms of the Plan described herein, as they may be amended from time to time. Any account balances in any other defined contribution plans maintained by an Employer or Affiliate shall be governed by the terms thereof, as they may be amended from time to time.

1.8      Supplements and Appendices . Supplements and appendices to the Plan may be adopted, attached to and incorporated into the Plan at any time in accordance with the provisions of Section 10.1 except that any amendment of Supplements A, B, C, D and E may be adopted separately by the Company’s Director of Compensation + Benefits. The provisions of any such supplements and appendices shall have the same effect that such provisions would have if they were included within the basic text of the Plan. Supplements and appendices shall supersede the other provisions of the Plan to the extent necessary to eliminate inconsistencies between the Plan provisions and the provisions of such supplements and appendices.

If the Participant does not respond to such re-solicitation in the manner proscribed in the communication of such re-solicitation, any prior direction under Section 6.4(a) shall be null and void and the Participant shall be deemed to have failed to make an investment election under the Plan. Accordingly, as provided under Section 6.4(a), the Participant shall be deemed to have directed his Account to be invested in the “default fund” designated by the Benefit Funds Committee.

(f)      Caterpillar 401(k) Retirement Plan Investment Election . Any prior investment elections made under the Caterpillar 401(k) Retirement Plan that are valid as of December 31, 2010 shall be transferred to this Plan and thereafter continued until a Participant makes an affirmative election to change his investments in accordance with this Article VI. Consequently, all Contributions made on behalf of a Participant under this Plan and any amounts transferred to this Plan from the Caterpillar 401(k) Retirement Plan shall continue to be invested according to such investment election until a Participant makes an affirmative election to change his investments in accordance with this Article VI.

ARTICLE VII

VESTING

7.1      Non-elective Contributions Account . A Participant shall vest in his Non-elective Contributions Account under the following schedule; provided, however, that a Participant shall become fully vested upon attainment of Normal Retirement Age or if he dies: (A) while actively employed by the Employer or an Affiliate or (B) while performing Qualified Military Service:

7.2      All Other Accounts . A Participant shall be fully vested at all times in his 401(k) Contributions Account, Matching Contributions Account, Rollover Account, Top-Heavy Contributions Account, Prior Plan Contributions Account, Roth 401(k) Contributions Account, Roth Rollover Account, After-tax Contributions Account and QNEC Account.

7.3      Forfeitures . A Participant shall forfeit his interest in his Non-elective Contributions Account to the extent not vested in accordance with Section 7.1 upon the earlier of:

(a)      the date on which the Participant experiences 60 consecutive months of a Break in Service or 60 consecutive months of a Period of Severance;

(b)      the date on which the Participant receives a distribution of his vested Account; or

(c)      40 days after Termination of Employment (or such other time as determined by the Administrator) if the Participant does not have a balance in his 401(k) Contributions Account, Rollover Account, Top-Heavy Contributions Account, Prior Plan Contributions Account, Roth 401(k) Contributions Account, Roth Rollover Account, After-tax Contributions Account or QNEC Account.

If a portion of a Participant’s Account is forfeited, qualifying employer securities within the meaning of Section 4975(e)(8) of the Code must be forfeited only after the remaining assets have been forfeited.

7.4      Rehired Participants .

(a)      A former Participant who forfeited the non-vested portion of his Non-elective Contributions Account in accordance with the provisions of this Article before the date he incurs 60 consecutive months of a Break in Service or 60 consecutive months of a Period of Severance and who is reemployed by an Employer or Affiliate before experiencing 60 consecutive months of a Break in Service or 60 consecutive months of a Period of Severance shall have such forfeited amounts restored to his Non-elective Contributions Account.

(b)      The forfeited balance of a Participant’s Account that is restored to a Participant’s Account hereunder shall not be adjusted for earnings and losses that occurred during the period beginning on the date the non-vested portion of the Participant’s Account was forfeited and ending on the earliest date such amounts could have been forfeited under the terms of Section 411(a)(7) of the Code. Funds needed in any Plan Year to restore the Account of a Participant with the amounts of prior forfeitures in accordance with the preceding sentence shall come first from existing Plan forfeitures or additional Employer Contributions.

(c)      A former Participant who forfeited the non-vested portion of his Account on or after the date he incurs 60 consecutive months of a Break in Service or 60 consecutive months of a Period of Severance and who is reemployed by an Employer shall not have such forfeited amounts restored to his Account.

7.5      Disposition of Forfeitures . Any amounts forfeited pursuant to this Article VII shall be applied to reduce Employer Contributions or to offset administrative expenses.

ARTICLE VIII

PAYMENT OF BENEFITS

8.1      Methods of Benefit Payment .

(a)      Normal Form of Payment . The normal form of payment of a Participant’s benefit, whether to the Participant or a Beneficiary, shall be a cash lump sum distribution equal to the Participant’s total Account Balance valued as of the Accounting Date coincident with or immediately prior to such distribution, and, except as otherwise provided herein, all benefits shall be paid in such form.

(b)      Protected Benefits . Notwithstanding the foregoing, if the account of any Participant under any other plan is transferred to the Plan under circumstances in which the Treasury Regulations under Section 411(d)(6) of the Code require forms of benefit provided under such plan to be protected, such Participant shall have the right to have his account balance transferred, plus, the share of income allocable to such balance, distributed in any form provided under such prior plan.

8.2      Distributions upon Termination of Employment .

(a)      Small Account Balances . If, at the time of a Participant’s Termination of Employment, his Account Balance does not exceed $5,000, the entire amount of the Account Balance shall be distributed to such Participant as soon as administratively feasible, in accordance with rules and procedures established by the Administrator. The balance in a Participant Rollover Account shall not be included in determining whether his Account Balance exceeds $5,000 (but his Rollover Account shall also be distributed if the remainder of his Account Balance does not exceed $5,000); provided that, if the Participant’s Account Balance (including his Rollover Account) exceeds $1,000 and 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 this Section 8.2, the Administrator will pay the distribution in a direct rollover to an individual retirement plan designated by the Administrator.

(b)      Termination of Employment . If a Participant incurs a Termination of Employment, and paragraph (a) does not apply to such Participant, then he may elect to receive the distribution of his Account Balance as soon as administratively feasible following such Termination of Employment, subject to the provisions of Section 8.2(c). Such distribution shall be made in the normal form provided in Section 8.1(a). A Participant who does not elect to begin receiving his distribution at the time of his Termination of Employment may subsequently elect to withdraw all or a portion of his Account at any time in accordance with rules and procedures established by the Administrator.

(c)      Latest Commencement Date . Anything else contained herein to the contrary notwithstanding, in no event shall distribution of a Participant’s Account begin later than April 1 of the calendar year following the later of the calendar year in which the Participant attains the age of 70½ or incurs a Termination of Employment; provided that in the case of a Participant who is described in paragraph (1)(i) of the definition of Highly Compensated Employee in the year in which he attains the age of 70½, distribution shall commence not later than April 1 of the following calendar year even if he is still employed. Such distribution shall be paid in accordance with Supplement G and Treasury Regulations issued pursuant to Section 401(a)(9) of the Code and any rules and procedures established by the Administrator.

8.3      Payments after a Participant’s Death .

(a)      Designation of Beneficiaries . The Account of a Participant who dies before his Account has been distributed in full shall be distributed to his Beneficiary or Beneficiaries as provided herein:

Beneficiary, subject to the rights of the Participant’s Spouse under clause (2) below. No designation of a Beneficiary or change thereof shall be effective until it has been received by the Administrator. The Administrator shall be entitled to rely upon the last designation filed by the Participant prior to his death.

(b)      Death of a Participant . Upon the death of a Participant, the remaining balance of the Participant’s Account shall be distributed among his Beneficiaries in the manner and form of required minimum distributions in accordance with Supplement G. Notwithstanding the foregoing, a Beneficiary may from time to time request withdrawals of all or any portion of his share of such Participant’s Account; provided that in no event shall the sum of any such withdrawals and distributions during any Plan Year be less than the minimum amount required to be distributed during such Plan Year in accordance with Supplement G.

8.4      Purpose of Limitations; Authority of Administrator . The provisions of Sections 8.1, 8.2 and 8.3 are intended to comply with the requirements of Section 401(a)(9) of the Code, including specifically the minimum distribution incidental death benefit rule of Section 401(a)(9)(G), and Treasury Regulations Section 1.401(a)(9)-2 through Section 1.401(a)(9)-6, as issued in final form on April 16, 2002, and shall be construed accordingly. Said Code and Treasury Regulation provisions are hereby incorporated herein by this reference, and shall control over any form of distribution provided in the Plan that is inconsistent therewith. To the extent that said Treasury Regulations provide for any elections or alternative methods of compliance not specifically addressed in Sections 8.1, 8.2 and 8.3, the Administrator shall have the authority to make or revoke such election or utilize such alternative method of compliance.

8.5      Direct Transfers . Any Participant or Alternate Payee who is entitled to receive a distribution to which this Section 8.5 applies shall have the right to direct the transfer of all or a portion of such distribution directly to an individual retirement account or annuity qualified under Section 408 of the Code (other than an endowment contract) (an “IRA”), or to a defined contribution pension or profit-sharing trust qualified under Section 401(a) of the Code, annuity plan qualified under Section 403(a) of the Code, or other “eligible retirement plan” as defined in Section 402(c)(8)(B) of the Code, which will accept such a transfer, which, effective January 1, 2008, shall include a Roth individual retirement account under Section 408A of the Code. The surviving spouse of a Participant shall similarly be entitled to direct the transfer of all or a portion of any distribution to which this Section 8.5 applies. The Administrator shall furnish each Participant, Alternate Payee or surviving Spouse to whom this Section 8.5 applies with a notice describing his right to a direct transfer and the tax consequences of a distribution. Such notice shall be furnished not more than 90 days nor less than 30 days before the Participant, Alternate Payee or surviving spouse is entitled to receive such distribution, and no distribution shall be made until 30 days after he has received such notice unless he waives such 30 day period. The provisions of this Section 8.5 shall apply to all distributions from the Trust that are “eligible rollover distributions” as defined in Section 402(c)(4) of the Code. The provisions of this Section 8.5 shall not apply to the portion of any distribution that is necessary to meet the minimum distribution requirements of Section 401(a)(9) of the Code and any hardship withdrawal. The Administrator may adopt administrative procedures to implement direct transfers, which may vary the time periods and minimum amounts set forth above, to the extent consistent with final Treasury Regulations issued under Section 401(a)(31) of the Code. Notwithstanding the foregoing, with respect to any distribution made to a Beneficiary who is a “designated beneficiary” (as defined by Section 401(a)(9)(E) of the Code) and who is not the surviving spouse of the Participant, such Beneficiary may elect a direct trustee-to-trustee transfer of the eligible portion of such distribution to an individual retirement plan established for the purposes of receiving the distribution in accordance with Section 402(c)(11) of the Code. For

avoidance of doubt, a Same-Sex Domestic Partner shall be considered a “designated beneficiary” who is not the surviving Spouse of a Participant and shall only be entitled to an eligible rollover distribution under the rules for a designated beneficiary.

8.6      Missing Participants and Beneficiaries . Neither the Sponsor, an Employer, the Administrator, the Benefit Funds Committee nor the Trustee shall be obliged to search for, or ascertain the whereabouts of, any Participant or Beneficiary. If all or a portion of an Account that remains to be distributed to a Participant or Beneficiary at a time when the Administrator is unable to locate the Participant or Beneficiary, then such Account shall be forfeited and the amounts used first to reduce future Contributions that the Employers would otherwise be required to make to the Plan and second to pay Plan expenses. If the Participant or Beneficiary subsequently makes a proper claim for a distribution under the Plan, or if the person who would be entitled to receive such distribution upon the death of such Participant or Beneficiary establishes to the satisfaction of the Administrator that such Participant or Beneficiary has died, then such Account shall be restored and the Employers shall contribute any additional amount necessary to restore such Account.

8.7      Payment With Respect to Incapacitated Participants or Beneficiaries . If any person entitled to a distribution of benefits under the Plan is under a legal disability, or in the Administrator’s opinion, is incapacitated in any way so as to be unable to manage his financial affairs, the Administrator may direct the payment of such distribution to such person’s legal representative or to a relative or friend of such person for such person’s benefit or the Trustee may direct the application of such benefits to the benefit of such person. Payments made in accordance with this Section 8.7 shall discharge all liabilities for such distribution under the Plan.

8.8      Limitation on Liability for Distributions . Anything else contained herein to the contrary notwithstanding, any distribution made under any provision of this Article VIII to a person whom the Administrator determines in good faith to be entitled to receive such distribution shall fully discharge the Plan’s obligation to make such distribution, and neither the Plan, the Trustee, the Administrator, the Sponsor, the Benefit Funds Committee, nor any Employer shall have any further liability with respect to such distribution to the Participant or any other person claiming through him.

8.9      In-Service Withdrawals.

(a)      Non-Hardship Withdrawals . Participants shall be permitted to make withdrawals at any time from Rollover Accounts and from After-tax Contributions Accounts. Participants shall be permitted to make withdrawals from their 401(k) Contributions Account, Matching Contributions Account, Non-elective Contributions Account, Prior Plan Contributions Account, Roth 401(k) Contributions Account, Roth Rollover Account, or QNEC Account without demonstrating a financial hardship after they have attained the age of 59½, in accordance with rules and procedures established by the Administrator.

(b)      Military Withdrawals .     A Participant who is called into active duty in Qualified Military Service for more than 30 days may take a distribution from his 401(k) Contributions Account or Roth 401(k) Contributions Account as if he had experienced a Termination of Employment. A Participant who receives an active duty withdrawal may not make any 401(k)

Contributions under this Plan or any contributions to other plans maintained by the Employer or an Affiliate for six months after receiving the active duty withdrawal.

Additionally, effective January 1, 2013, a Participant who is a member of a reserve component (as defined in United States Code, Title 37, Section 101) and is ordered or called to active duty for a period in excess of 179 days after September 11, 2001 may take a distribution from his 401(k) Contributions Account or Roth 401(k) Contributions Account during the period beginning on the date the Participant is ordered or called to active duty and ending at the close of the active duty period.

(c)      Hardship Withdrawals . A Participant may receive a hardship withdrawal as provided below:

(d)      Disability Withdrawal .     A Participant who is Disabled may take a distribution from his Account Balance as if he had experienced a Termination of Employment.

(e)      Limitations on Withdrawals . The Administrator may adopt uniform and non-discriminatory procedures imposing limitations on the number, frequency, or amount of hardships pursuant to this Section 8.9.

(f)      Treatment of Withdrawals . Except as otherwise specifically provided herein, a withdrawal shall be treated as a distribution for all purposes of the Plan.

8.10      Loans .

(a)      Eligibility for Loans . An Active Participant, or an Inactive Participant who is still an Employee, may borrow against his vested Account Balance subject to the provisions set forth herein. Such loans shall be available to all Participants on a reasonably equivalent basis and shall not be made available to Highly Compensated Employees, officers or shareholders in an amount greater than the amount (stated as a percentage of the Participant’s vested Account) made available to other Participants.

(b)      Maximum Amount of Loans . A loan to any Participant, when added to the outstanding balance of all other loans to him from the Plan, shall not exceed the lesser of (i) 50 percent of the Participant’s vested Account Balance, or (ii) $50,000 reduced by the excess (if any) of (A) the highest outstanding balance of loans from the Plan during the one-year period ending on the day before the date of the loan over (B) the outstanding balance of loans from the Plan on the date of the loan. For purposes of this section, all plans of the Employer and any Affiliate that permit participant loans shall be treated as one plan.

(c)      Payment Terms . Each loan to a Participant shall provide for repayment over a period not to exceed five years, or a longer term in the case of a loan that is used to acquire any dwelling unit which within a reasonable time is used (determined at the time the loan is made) as the principal residence of the Participant. Each such loan shall provide for substantially level amortization (with payments not less frequently than quarterly) over the term of the loan. Notwithstanding the foregoing, payments shall be suspended during any Leave of Absence; provided that, except for Qualified Military Service, the period during which payments are suspended shall not exceed one year.

(d)      Interest Rate . Each such loan shall bear interest at a reasonable rate to be determined by the Trustee in a nondiscriminatory manner, taking into consideration interest rates currently being charged by commercial lending institutions for similar loans.

(e)      Collateral and Enforcement . Each loan made to a Participant shall be secured by not more than 50 percent of the vested portion of the Participant’s Account. Each Participant who is an Employee shall be required to execute a wage withholding agreement providing for payments of principal and interest to be withheld from his compensation. Each loan shall also provide that Termination of Employment by the Participant is an event of default, whether or not a distribution is made from the Participant’s Account, permitting the balance of the loan to be offset against the Participant’s Account. Anything else contained herein to the contrary notwithstanding, no amount shall be offset against a Participant’s 401(k) Contributions Account or Roth 401(k) Contributions Account except at a time that a distribution would be permitted to the Participant, whether or not a loan is treated as a distribution for tax purposes under Section 72(p) of the Code.

(f)      Accounting Treatment . The loan shall for purposes of Article VI be treated as an investment of the funds credited to the Participant’s Account. For purposes of the accounting adjustments provided for by Article VI as of each Accounting Date until the loan is repaid in full, the Administrator shall reduce the Participant’s Account Balance by the unpaid balance on such loan and shall increase his Account by the amount of interest and other payments made by the Participant. Each such reduction or increase shall be applied to the Participant’s Account and the investment funds in which his Account is invested in such proportions as he may specify in accordance rules and procedures adopted by the Administrator, or, if he fails to specify the proportions, shall be applied proportionately to such investment funds.

(g)      Other Restrictions . No loan shall be made to any Participant in an amount of less than $1,000, or such lesser amount as the Administrator may establish on a uniform basis. The Administrator may establish additional restrictions on the number, frequency, or terms of loans, including the fees charged therefor, provided that such restrictions are applied in a uniform and

non-discriminatory manner and do not cause loans to fail to be available to Participants on a reasonably equivalent basis.

(h)      Certain Former Caterpillar 401(k) Retirement Plan Participants . If an individual becomes an Eligible Employee and immediately prior to becoming an Eligible Employee the individual was participating in the Caterpillar 401(k) Retirement Plan (“RP”) and had an outstanding loan balance under RP, all accounts and liabilities maintained under RP on behalf of such Eligible Employee (including the loan account) shall be transferred to the Plan. The transferred loan balance shall be treated as a loan by the Plan, but shall be subject to all terms and conditions of the loan’s promissory note (subject to minor adjustments in repayment amounts and dates, if any, resulting from changes in payroll frequency) and such loan shall be subject to such additional rules and procedures as the Administrator may establish. Notwithstanding the foregoing, this Section 8.10(h) shall only apply if the Administrator determines that the Eligible Employee’s Employer is unable to process the RP loan payments through its payroll system.

  

ARTICLE IX

PLAN ADMINISTRATION

9.1      General Fiduciary Standard of Conduct . Each fiduciary under the Plan shall discharge his duties hereunder solely in the interest of the Participants and their Beneficiaries and for the exclusive purpose of providing benefits to the Participants and their Beneficiaries and defraying the reasonable expenses of administering the Plan and the Trust. Each fiduciary shall act with the care, skill, prudence and diligence under the circumstances then prevailing that a prudent man, acting in a like capacity and familiar with such matters, would use in the conduct of an enterprise of a like character and with like aims, in accordance with the documents and instruments governing the Plan and the Trust, insofar as such documents and instruments are consistent with this standard.

9.2      Allocation of Responsibility Among Fiduciaries . Plan fiduciaries shall have only those powers, duties, responsibilities and obligations specifically delegated to them under this Plan or as delegated to them by resolutions or other actions of the Board of Directors of the Sponsor taken from time to time. In addition, any authority to amend or terminate the Plan may be delegated by resolutions or other actions of the Board of Directors of the Sponsor taken from time to time. In case of any conflict between any provision of this Plan and any delegation by action of the Board of Directors of the Sponsor, the delegation by action of the Board of Directors of the Sponsor shall always govern. The Sponsor, the Administrator (if other than the Sponsor), members of the Benefit Funds Committee, the Trustee, if any, and any investment manager shall each be a “named fiduciary” as defined in Section 402(a)(2) of ERISA.

Subject to this Section 9.2, the following additional provisions shall apply:

(a)      The Sponsor may delegate fiduciary duties (other than trustee duties) to persons other than named fiduciaries, and may approve any allocation of fiduciary duties among named fiduciaries, as provided in Section 405(c) of ERISA and in accordance with Sections 6.4 or 9.3 hereof, as applicable.

(b)      The Corporate Treasurer shall have the authority to delegate duties relating to Plan financial matters to the Benefit Funds Committee.

(c)      If there is more than one Trustee, they may enter into agreements among themselves with respect to the allocation of trustee responsibilities with the consent of the Administrator as provided in Section 405(b) of ERISA.

(d)      To the extent permitted by law, neither the Plan Administrator nor any director, officer, or employee of the Sponsor or the Employers (including any member of the Benefit Funds Committee) shall incur any personal liability of any nature in connection with any act done or omitted to be done in good faith under or in connection with the Plan.

9.3      Administrator . The Plan shall be administered by the Sponsor. The Administrator reserves the authority to adopt such procedures, which shall be applied in a uniform and nondiscriminatory manner, as it deems necessary to administer the Plan and to determine all questions arising under the Plan. The Administrator may designate any person, entity, committee, board or similar body to act as named fiduciary or fiduciaries, or to act as the designee of the Administrator as a fiduciary, under the Plan and allocate any and all of its duties and responsibilities under the Plan to such named fiduciary or fiduciaries, or such designee(s). If the Administrator so allocates any of its duties and responsibilities under the Plan, such named fiduciary, fiduciaries or designee(s) shall be substituted for the Sponsor whenever such term appears under the Plan with respect to any duties and responsibilities so allocated. Notwithstanding any such delegation, the Administrator shall continue to be the “plan administrator” as defined under Section 414(g) of the Code and the “administrator” as defined in Section 3(16)(A) of ERISA, unless otherwise explicitly provided in such delegation.

The Administrator, or its duly authorized designee, shall have discretionary authority to interpret the terms of the Plan and to determine eligibility for and entitlement to Plan benefits and shall have the discretion to take any other action with respect to the Plan in accordance with any applicable delegation. Prior exercise of such authority shall not create a precedent or obligate the Administrator (or its designee, as applicable) to exercise its authority in the same or similar fashion thereafter. Any interpretation, determination or action shall be given full force and effect and shall not be given “de novo” review if challenged by any court, agency or other authority.

9.4      Powers and Duties of Administrator . In addition to all other powers and duties set forth herein, the Administrator shall have all necessary power to accomplish its duties under the Plan, including but not limited to, the power to:

(a)      construe and interpret the Plan, decide all questions of eligibility and determine the amount, manner and time of payment of any benefits under the Plan;

(b)      prescribe procedures to be followed by Participants or Beneficiaries filing applications for benefits or taking any other action under the Plan;

(c)      assist any Participant or Beneficiary regarding any rights, benefits or elections available under the Plan;

(d)      adopt reasonable procedures for determining whether any order, judgment or decree constitutes a Qualified Domestic Relations Order;

(e)      prepare and file such Plan descriptions and annual reports as may be required by ERISA, the Code or other applicable legislation;

(f)      act on direction from the Benefit Funds Committee regarding matters arising under Sections 1.5 and/or 6.4 of the Plan (including ensuring that investment elections made pursuant to Section 6.4(a) are processed and that the disclosures required by ERISA Section 404(c) and the U.S. Department of Labor Regulations issued thereunder are furnished) or other financial matters affecting the Plan;

(g)      receive from the Employers, Participants and Beneficiaries such information as shall be necessary for the proper administration of the Plan;

(h)      furnish the Employers, upon request, such annual reports with respect to the administration of the Plan as are reasonable and appropriate;

(i)      maintain all the necessary records for the administration of the Plan;

(j)      receive, review and keep on file (as it deems convenient and proper) reports of benefit payments made by the Trustee and reports of disbursements for expenses directed by it;

(k)      to the extent permitted under applicable policies of the Sponsor, retain service providers, consultants, and professional advisors, as necessary, to assist in the fulfillment of its duties under the Plan; and

(l)      do all other acts which the Administrator in its sole discretion deems necessary and proper to accomplish and implement its responsibilities under the Plan.

The Administrator, or its designee, shall have the discretionary authority to establish reasonable rules and procedures to carry out its responsibilities under the Plan and may delegate (or further delegate, as applicable) such duties and responsibilities in a writing that is filed with the Sponsor’s Secretary. Any rule or procedure adopted by the Administrator, or any decision, ruling, interpretation, or determination made by the Administrator, in good faith and in accordance with the applicable fiduciary standards of ERISA shall be final, binding and conclusive on all Employers, Employees, Participants, Beneficiaries and all persons claiming through them. Rules and procedures adopted by the Administrator in accordance with this Section 9.4 may alter any provision of the Plan that is ministerial or administrative in nature and not governed by applicable law or regulation, including varying the time required for performing any act, without a formal amendment to the Plan. Wherever the Plan provides for any action to be taken or election to be made by a Participant or Beneficiary, the Administrator may establish procedures providing for such action to be taken or election to be made through the use of electronic mail, a telephone voice response system, or other electronic means, to the extent permitted by applicable law. Any delegation of authority made, rule or procedure adopted, or other action taken, by the Administrator shall remain valid and in effect until changed in accordance with the Plan.

9.5      Compensation and Expenses . All fiduciaries and who are Employees shall serve without additional compensation for their services hereunder. Professional Trustees and investment managers shall be paid such compensation as may be agreed upon by the Administrator. The expenses of the administration of the Plan, including by way of example but not limitation, expenses incurred in the hiring of consultants, advisors, investment managers, attorneys and accountants, may be paid by the Trust (including directly from a Participant’s Accounts), provided that the fiduciaries conclude that payment of such compensation and expenses by the Trust is permissible under ERISA. To the extent that the Plan administration expenses are not paid by the Trust, they shall be paid by the Employer.

9.6      Indemnification by Employers . The Employers shall indemnify the Administrator, all officers, employees, members and managers of the Administrator, and each Trustee for, and hold them harmless from and against, any and all liabilities, losses, costs or expenses (including reasonable attorneys’ fees) of whatsoever kind and nature which may be imposed on, incurred by or asserted against them at any time by reason of their service under the Plan or the Trust as long as they did not act dishonestly or engage in willful misconduct or gross negligence in their official capacities hereunder, including all expenses reasonably incurred in their defense if the Employers fail to provide such defense.

9.7      Service in Multiple Capacities . Any person may serve in more than one fiduciary capacity hereunder, including but not limited to service as a member of the Benefit Funds Committee and as a Trustee.

9.8      Claims Procedure .

(a)      Filing of Claim . A Participant or any other person claiming the right to a benefit of any type under the Plan (a “claimant”), must, as a prerequisite to payment of such benefit, file a claim for such benefit in accordance with the procedures of this Section 9.8, provided that nothing contained herein shall preclude the Administrator or its delegate from establishing procedures for the routine payment of benefits without the filing of a formal claim in undisputed cases. Claims for benefits shall be filed with the Benefit Appeals Committee using forms prescribed by it and shall authorize the Benefit Appeals Committee to conduct such examinations as may be necessary to determine the validity of the claim and to take such steps as may be necessary to facilitate the payment of any benefits to which the claimant may be entitled under the terms of the Plan. All claims for benefit shall be filed not later than one year after the claimant knows, or with the exercise of reasonable diligence would know, of the basis for the claim. Nothing in the preceding sentence shall be construed to permit the forfeiture of any Participant’s undisputed benefit solely by reason of the failure to file a claim within any period after such claim becomes payable or otherwise to conflict with Section 8.6.

(b)      Notice of Denial . Whenever a claim for benefits by the claimant has been denied by the Benefit Appeals Committee, a written notice of denial shall be given to the claimant, prepared in a manner calculated to be understood by him without legal assistance and setting forth the specific reasons for the denial and explaining the procedure for an appeal and review of the decision by the Benefit Appeals Committee, and the claimant’s right to file an action under Section 502 of ERISA, subject to paragraph (d), if the appeal is unsuccessful. Such notice shall be furnished not later than

90 days after the claim has been filed (which 90 day period may be extended for up to an additional 90 days if special circumstances require and notice of the extension, explaining the reason for the extension and an estimate of when the review of the claim will be completed, is furnished to the claimant prior to the end of the first 90 day period).

GENERAL PROVISIONS

11.1      No Employment Guarantee .

Under no circumstances shall the terms of employment with an Employer of any Participant be modified or in any way affected hereby. The maintenance of the Plan shall not constitute a contract of employment with any Employer. Participation in the Plan will not give any Participant a right to be retained as an employee of any Employer.

Any final judgment which is not appealed or appealable and may be entered

(c)      General Limitations on Returns . The amount returned to an Employer pursuant to subparagraph (b)(1) or (b)(2) shall be the excess, if any, of the amount actually contributed over the amount that either would have been contributed had the mistake not occurred, or that is determined to be deductible, as applicable. Such amount shall be reduced by a pro rata share of any losses incurred by the Trust, but shall not include any earnings. A Contribution may be returned even though it has been allocated to a Participant’s Account, and such Account may be reduced accordingly, but in no event shall any account be reduced below the amount that would have been allocated to it if the mistaken or non-deductible Contribution had not been made. If the amount

returned under any provision of paragraph (b) represents a 401(k) Contribution, it shall be promptly paid by the Employer to the Participant.

11.13      Overpayments . If it is determined that the amounts under the Plan should not have been paid or should have been paid in a lesser amount, written notice thereof shall be given to the recipient of such amounts (or his legal representative) and he shall repay the amount of overpayment to the Trustee or other funding media under the Plan.

A portion of the Plan is intended to be a stock bonus plan as defined in Treasury Regulations Section 1.401-1(b)(1)(iii) and a non-leveraged employee stock ownership plan (“ESOP”) satisfying the requirements of Sections 401(a), 409, and 4975(e) of the Code. The ESOP portion of the Plan is designed to be invested primarily in Company Shares, which are qualifying employer securities within the meaning of Section 4975(e)(8) of the Code. For purposes of this Supplement F, each Participant shall be considered to be a “named fiduciary” within the meaning of (and to the extent permitted under) Section 402(a)(2) of ERISA with respect to the treatment of dividends paid on Company Shares credited to participants’ accounts.

F-2.      ESOP Portion . The ESOP portion of the Plan shall consist of all amounts credited to the Company Shares Fund. The non-ESOP portion of the Plan shall consist of the balance of amounts credited to participants’ accounts.

F-3.      Dividend Election . Notwithstanding anything to the contrary in paragraph 6.4(c)(4) (or its successor provision), a Participant shall be offered an election to receive a payment or distribution of cash dividends that are paid on or after December 1, 2000, on Company Shares credited to his accounts, including cash dividends paid on Company Shares credited to the Company Shares Fund. The Administrator may provide that this election may be offered:

(a)      before a dividend is paid, in which case the dividend may be paid by the Company directly to the Participant, or to the Plan and then distributed to the Participant not later than ninety (90) days after the close of the Plan Year in which paid to the Plan, or

(b)      after the dividend has been paid, in which case the dividend paid to the Plan shall be distributed to the Participant within ninety (90) days after the close of the Plan Year in which paid to the Plan.

A Participant shall be deemed to elect to have the cash dividends automatically reinvested in Company Shares, unless the participant files a timely election with the Administrator to have all or a portion of the cash dividends paid to the participant. Dividends that are not paid or distributed to a Participant pursuant to the election described above shall remain subject to the requirements of paragraph 6.4(c)(4). The Administrator shall determine the scope, manner and timing of the elections, dividend payments or distributions, and reinvestment in Company Shares described in this Section F-3 and paragraph 6.4(c)(4) in any manner that is consistent with section 404(k) and other applicable provisions of the Internal Revenue Code of 1986 and the Employee Retirement Income Security Act of 1974, as amended.”

F-4.      Distribution in the Form of Company Shares . Notwithstanding anything to the contrary in Article VIII, a Participant entitled to a distribution from the Plan may demand that his ESOP accounts shall be distributed in the form of Company Shares.

F-5.      Put Option . In accordance with Section 409(h)(4), (5) and (6) of the Code, if the Company Shares are or become not readily tradable on an established market, then any participant who otherwise is entitled to a total distribution from the Plan shall have the right (hereinafter referred to as the “Put Option”) to require that his Company Shares be repurchased by the Company. The Put Option shall only be exercisable during the sixty-day (60-day) period immediately following the date of distribution, and if the Put Option is not exercised within such sixty-day (60-day) period, it can be exercised for an additional sixty (60) days in the following plan year.

(a)      The amount paid for the Company Shares pursuant to the exercise of a Put Option as part of a total distribution shall be paid in substantially equal periodic payments (not less frequently than annually) over a period beginning not later than thirty (30) days after the exercise of the Put Option and not exceeding five (5) years. There shall be adequate security provided and reasonable interest paid on an unpaid balance due under this paragraph.

(b)      If the Company is required to repurchase Company Shares as part of an installment distribution, the amount to be paid for the Company Shares will be paid not later than thirty (30) days after the exercise of the Put Option.

F-6.      Voting of Company Shares . The Administrator shall furnish or cause to be furnished to each participant who has Company Shares credited to his Accounts notice of the date and purpose of each meeting of the stockholders of the Company at which shares of Company Shares are entitled to be voted. The Administrator shall request from each such participant instructions as to the voting at that meeting of Company Shares credited to his Accounts. If the participant furnishes such instructions within the time specified in the notification given to him, the Trustee shall vote such Company Shares in accordance with the participant’s instructions. All Company Shares credited to accounts as to which the Trustee does not receive voting instructions as specified above shall be voted by the Trustee proportionately in the same manner as it votes Company Shares to which the Trustee has received voting instructions as specified above, unless the Trustee, in its sole discretion, determines that it would not be consistent with its fiduciary duties under ERISA to do so.

F-7.      Full Vesting . A participant shall be fully vested in and have a non-forfeitable right to any cash dividends that are subject to the dividend election provisions of Section F-3, without regard to whether the Participant is vested in the Company Shares with respect to which the dividend is paid.

F-8.      Diversification . A Participant who has attained age fifty-five (55) and completed at least ten years of participation in the Plan may direct the Trustee to diversify a portion of the balance in his Account, as provided in Section 401(a)(28)(B) of the Code. For each of the first five Plan Years after the Participant attains age 55, the Participant may elect to diversify an amount that is not less than 25% of the number of shares of qualifying employer securities allocated to his Account, less all shares with respect to which an election under this Section F-8 has already been made. In the case of the sixth Plan Year, the Participant may elect to diversify an amount that is not less than 50% of the number of shares of qualifying employer securities allocated to his Account (less all shares with respect to which an election under this Section F-8 has already been made).

The term “qualified election period” shall mean the six Plan Year period beginning with the Plan Year in which a Participant has attained age fifty-five (55) and ten years of service. A Participant’s election to diversify his Account may be made within each Plan Year during the qualified election period and shall continue for the ninety (90)-day period immediately following the last day of each Plan Year in the qualified election period. Once a Participant makes such election, the Plan must complete diversification in accordance with such election within ninety (90) days after the end of the period during which the election could be made for the Plan Year.

F-9.      Hardship Withdrawal . A participant who wishes a hardship withdrawal, if any, first must elect to have paid to him all cash dividends that are subject to the dividend election provisions of Section F-3, effective as of the first date allowed for new elections or changes in elections in accordance with the provisions of Section F-3.
