PARTICIPATION. Section 3.1. Who May Participate. Participation in the Plan is limited to those Eligible Executives selected by the Committee for participation in the Plan. Section 3.2. Time and Conditions of Participation. An Eligible Executive shall become a Participant only upon the Eligible Executive's compliance with such terms and conditions as the Committee may from time to time establish for the implementation of the Plan, including but not 10 limited to, any condition the Committee may deem necessary or appropriate for the Company to meet its obligations under the Plan. The Company may, in its sole discretion, purchase insurance on the lives of each Participant. The Committee may, in its sole discretion, reject for participation in the Plan Eligible Executives who fail or refuse to cooperate with the Company in obtaining insurance on their lives.

Except as otherwise specified in the Plan, the Company may not terminate an individual's participation in the Plan; provided, however, that if the Committee, in its discretion, determines that it is likely that a Participant would not be considered for any period to be a member of a select group of management or highly compensated employees, within the meaning of Sections 201(2), 301(a)(3) and 401(a)(l) of ERISA, the Committee may require that no contributions be made to the Plan by or on behalf of such Participant during such period. Section 3.4. Missing Persons. If the Company is unable to locate the Participant or the Participant's Beneficiary for purposes of making a distribution, the amount of a Participant's benefits under the Plan that would otherwise be considered as nonforfeitable shall be forfeited on the first to occur of the following dates: (a) effective four years after the last date a payment of said benefit was made, if at least one such payment was made; (b) effective four years after the first date a payment of said benefit was directed to be made by the Company pursuant to the terms of the Plan, if no payments have been made; or (c) effective on the date of termination of 11 the Plan. If a person is located after the date of such forfeiture, the benefits for such Participant or Beneficiary shall not be reinstated under the Plan. Section 3.5. Relationship to Other Plans. Participation in the Plan shall not preclude participation of the Participant in any other fringe benefit program or plan sponsored by the Company for which such Participant would otherwise be eligible. ARTICLE 4. ENTRIES TO THE ACCOUNT. Section 4.1. Deferrals. 4.1.1. Deferral Elections. Each Participant wishing to defer Compensation under the Plan shall enter into a deferral election, which shall specify the amount of Compensation the Participant wishes to have deducted from the Participant's pay and contributed to the Plan. Deferral elections with respect to Base Salary must specify the percentage (stated as an integer) of the Compensation that the Participant wishes to have deducted from Base Salary. Deferral elections with respect to Incentive Compensation must specify either the percentage (stated as an integer) or the dollar amount, or a combination of percentage and dollar amount, as determined by the Committee in its discretion, of the Compensation that the Participant wishes to have deducted from Incentive Compensation. 4.1.2. Timing of Elections. For Eligible Executives who first become eligible to participate in the Plan as of the Restated Effective Date, the deferral election shall be entered into before the Restated Effective Date. For Eligible Executives who first become eligible to participate in the Plan after the Restated Effective Date, the deferral election may be entered into during any Enrollment Period, which election shall then be effective 12 for the Plan Year following the Enrollment Period. A Participant's deferral election shall remain in effect unless and until changed by the Participant. A Participant may change a deferral election only during an Enrollment Period, in which case the change shall be effective for Compensation earned and accrued during the immediately following Plan Year. A deferral election will be effective to defer Compensation earned after the deferral election is entered into, and not before, except that for Eligible Executives who are eligible to participate in the Plan as of the Restated Effective Date, the deferral election with respect to Incentive Compensation may also apply to Incentive Compensation earned before the date that the Eligible Executive elects to participate in the Plan but paid after the Restated Effective Date, but only if the Eligible Executive elects to defer such payment during the Enrollment Period immediately preceding the Restated Effective Date. A deferral election shall be suspended during any period of time that such suspension is required in connection with a hardship withdrawal under any Plan of the Company or an Affiliate qualified under Section 401(a) of the Code. The Participant may not enter into a new deferral election after such suspension until a Plan Year that begins after the suspension has concluded. 4.1.3. Allocation Between Accounts. At the time a Participant makes the Participant's initial deferral election, the Participant shall specify the Account(s) the Participant wishes to open in the Plan. A Participant with a deferral election shall always have at least one Account in the Plan and may, at the Participant's election, have up to two Accounts, specifically, a Retirement Account and a Scheduled Withdrawal Account. A Participant may open a new Account (up to a total of the two Accounts) during an Enrollment Period. A Participant shall specify in the Participant's deferral election the 13 proportions in which the Participant's deferrals are to be allocated between the Participant's Retirement Account and the Participant's Scheduled Withdrawal Account. Provided, however, that no deferrals may be contributed to a Participant's Scheduled Withdrawal Account in the calendar year in which a distribution is to be made from said Account. 4.1.4. Limitation on Deferral Elections. A Participant may make a deferral election for any Plan Year provided that: (a) in no event may the amount deferred by a Participant for a Plan Year under both the Participant's Accounts exceed the Maximum Annual Deferral; and (b) the Participant's remaining Compensation, after all deferrals, is sufficient to enable the Employer to withhold from the Participant's Compensation (i) any amounts necessary to satisfy withholding requirements under applicable tax law; (ii) the amount of any contributions which the Participant may be required to make or may have elected to make under the various benefit plans of the Company or an Affiliate; and (iii) any other payroll deduction from Compensation required by law or authorized by the Participant. Section 4.2. Company Contributions. For each Plan Year that commences on or after the Restated Effective Date, the Company may, but shall but not be obligated to make a contribution to the Plan in such amount as the Company shall determine in its sole discretion. If a contribution is made for a Plan Year, it shall be credited as of such day in the Plan Year and to such Participant or Participants, whether employed by the Company or an Affiliate, as the Company shall determine in its sole discretion. The contribution on behalf of a Participant pursuant to this Section 4.2 shall be allocated to the Retirement Account of that Participant, to be credited to a Company Contributions subaccount under the Retirement Account. A Participant's 14 Company Contributions subaccount will be credited using such Crediting Rate as the Company shall determine in its sole discretion for a Plan Year, which rate is not required to be uniform among all Company Contributions subaccounts. Distribution of a Participant's Company Contributions subaccount will be made to a Participant only if the Participant remains employed with the Company or an Affiliate until death, Disability, Retirement, Sale, or a Change in Control, and shall thereupon be made in accordance with the applicable provisions of Article 5 in the same manner as the balance of the Participant's Retirement Account. If the Participant does not remain employed with the Company or an Affiliate until death, Disability, Retirement, Sale, or a Change in Control, then the amount in the Company Contributions subaccount shall be forfeited in favor of the Company. Section 4.3. Disability. If a Participant becomes Disabled, deferrals and Company Contributions (if any) shall continue to be allocated as described in Sections 4.1 and 4.2 during the period in which the Participant is entitled to receive Compensation from the Company or an Affiliate, other than compensation under a long term disability plan. If a Participant continues to be Disabled after such period, deferrals and other Plan contributions will cease. Section 4.4. Change in Eligibility Status. If a Participant in the Plan ceases to be an Eligible Executive, the Participant's deferrals to the Plan shall cease. No further Company Contributions under Section 4.2 shall be made to the Plan unless and until the employee again becomes an Eligible Executive. The Participant's Account shall continue to be credited with earnings and losses under Section 4.6 and shall be paid in accordance with Article 5. Section 4.5. Allocation to Accounts. During each Plan Year, the Company shall post to the appropriate Account(s) of each Participant the amount of Base Salary and Incentive Compensation to be deferred under such Account(s) as designated by the Participant in the 15 Participant's deferral election in effect for that Plan Year. Such allocation shall occur as of the dates that the Base Salary and Incentive Compensation would have been paid to the Participant. The Company shall also post to the Retirement Account amounts to be allocated to the Participant pursuant to Sections 4.2 and 4.3. Section 4.6. Earnings Crediting. 4.6.1 Earnings Credits for Accounts. Each Participant may request that the Scheduled Withdrawal Account or the Retirement Account be allocated to one or more investment indices selected by the Committee and credited or debited, as the case may be, with such earnings or losses as the Account would have been credited or debited had it been actually invested in such investment indices. The initial allocation request may be made at the time of opening of an Account, or for Nonqualified Accounts in existence immediately prior to the Restated Effective Date the initial request may be made during the Enrollment Period preceding the Restated Effective Date, to be effective as of the Restated Effective Date. The Committee shall in its discretion determine the Crediting Rate for a Participant who fails to make an initial allocation for a Plan Year. Once made, an investment allocation request shall remain in effect for all subsequent contributions until changed by the Participant. The Participant may change the investment allocation election by submitting a written request to the Committee. Participants may change elections no more than once in any calendar quarter. Such changes shall become effective as of the first day of the quarter after the Committee receives such written request. Crediting Rates shall continue to be credited or debited until the first to occur of (a) the Participant's termination of employment that is not the result of death, Disability or Retirement under the Plan; or (b) payment of all amounts owed to the Participant under 16 all Account(s). Provided, however, that during the Plan Year in which a final distribution of a Participant's Account is expected to occur, the Committee may apply to that Account the Dividend Rate for that Plan Year, rather than the Crediting Rate. Allocation requests shall be subject to such other requirements as established by the Committee. 4.6.2. No Guarantee of Account Value. The Participant agrees on behalf of the Participant and any Beneficiary to assume all risk in connection with any decrease in value of the Accounts resulting from the Participant's request and selection of any particular investment index under the Plan. 4.6.3. No Actual Investment. The Company is under no obligation to make investments or change investments in a manner consistent with the investment indices available under the Plan. The elections made by the Participant are for purposes of determining earnings and losses to be credited to the Accounts and not for the purpose of determining any actual investment of the assets of the Company or the Trust, if any. 4.6.4. Participant Statements. At least annually, the Company shall provide each Participant with a statement of the Participant's Account(s). ARTICLE 5. DISTRIBUTION OF BENEFITS. Section 5.1. Election of Benefit Commencement. 5.1.1. Distribution on Change in Control. During a Participant's first Enrollment Period under this Plan (and for Participants in the Plan immediately prior to the Restated Effective Date, during the Enrollment Period preceding the Restated Effective Date), the Participant may elect to commence distribution of all Accounts upon a Change in Control, if such a Change in Control should occur before the Account would otherwise be 17 payable under this Plan. If such election is not made at such time, then no acceleration of any Account shall occur upon a Change in Control under the Plan. 5.1.2. Scheduled Withdrawal Account. At the time a Participant opens a Scheduled Withdrawal Account under the Plan, the Participant shall establish the Specified Date for that Account. The Specified Date must be at least two years following the beginning of the Plan Year in which deferrals under the Scheduled Withdrawal Account commence. Section 5.2. Benefit Commencement. 5.2.1. Scheduled Withdrawal Account. Distribution of a Scheduled Withdrawal Account will be made in a lump sum during the calendar year in which the Specified Date occurs unless any of the following occurs before the Specified Date: (a) the Participant terminates employment (other than by reason of death, Disability or Retirement), in which case distributions will be made in a lump sum within 90 days following the Participant's termination of employment, or at the Company's discretion, in annual installments over no more than three years commencing within 90 days of Participant's termination of employment; (b) the Participant dies, in which case distributions will commence in the manner specified in Section 5.4.4; (c) the Participant terminates employment as a result of Disability or Retirement, in which case distribution will be made in a lump sum within 90 days following the Participant's termination of employment; (d) there occurs a Sale, in which case distribution will be made in a lump sum within 90 days following the Sale; or (e) there occurs a Change in Control and the Participant requested distribution to commence upon the Change in Control (as described 18 in Section 5.1.1), in which case distribution will be made in a lump sum within 90 days following the Change in Control. 5.2.2. Retirement Account. Distribution of a Retirement Account will commence in accordance with the following: (a) during January of the Plan Year following Retirement unless death, Disability, Sale or termination of employment occurs before such Retirement; (b) if the Participant dies before Retirement, in the manner specified in Section 5.4.4; (c) if the Participant terminates employment for reasons other than death, Disability or Retirement, in a lump sum within 90 days following the Participant's termination of employment, or at the Company's discretion, in annual installments over no more than three years commencing within 90 days of the Participant's termination of employment; (d) if there occurs a Sale before Retirement in a lump sum within 90 days following the Sale; (e) if there occurs a Change in Control and the Participant requested distribution to commence upon the Change in Control (as described in Section 5.1.1), in a lump sum within 90 days following the Change in Control, regardless of whether distribution had otherwise commenced in accordance with other provisions of this Plan; or (f) if the Participant is Disabled, within 90 days following the determination of Disability. Section 5.3. Form of Benefit Payment. At the time a Participant opens a Retirement Account under the Plan (or during the Enrollment Period immediately preceding the Restated Effective Date, for a Participant who was a Participant in the Plan before its restatement), the Participant shall select the period over which payments from the Account will be made. The Participant may elect to receive payment in the form of a lump sum or in monthly installments over 10, 15 or 20 years, or in a combination of lump sum and installments except that a 19 distribution upon a Change in Control or Sale, or a distribution upon termination of employment (other than death, Retirement, or Disability) will be made as set forth in Section 5.2.2(c). If no election is made, the Participant shall be deemed to have made an election to receive payments from the Retirement Account in monthly installments over 15 years. Provided, however, that the election by a Participant who was a Participant under the Plan before its restatement of a form of benefit payment other than a lump sum (if made during the Enrollment Period immediately preceding the Restated Effective Date) shall not be effective until January 1, 2003, and, anything hereinelsewhere to the contrary notwithstanding, all distributions made as a result of Disability or Retirement that would otherwise have occurred during 2002 shall be deferred until at least January 1, 2003, and shall thereafter be paid in accordance with the election made during said Enrollment Period. The Participant's selection of a method of benefit payment may be changed with an election filed with the Committee at least 13 months in advance of the date that benefit payments commence to the Participant. A Participant's Account will continue to be credited during the payment period with earnings and losses as set forth in Section 4.6, except that earnings and losses shall not be credited after termination of employment other than by reason of death, Disability, Retirement, Sale, or Change in Control. Section 5.4. Death Benefits. 5.4.1. Beneficiary Designation. At the time a Participant begins participation in the Plan, the Participant may designate primary and contingent Beneficiaries for death benefits payable under the Plan. Such Beneficiaries may be individuals or trusts for the benefit of individuals. If the Participant is married at the time of the Participant's death, the designation of a primary Beneficiary other than the Participant's spouse as sole primary Beneficiary shall be valid only if the Participant's spouse has consented in 20 writing to the naming of such primary Beneficiary and only if the spouse's consent has been notarized. A Beneficiary designation by a Participant shall be in writing on a form acceptable to the Committee and shall only be effective upon delivery to the Committee. A Beneficiary designation may be revoked by a Participant at any time by delivering to the Company a new Beneficiary designation form. The Beneficiary designation form last delivered to the Committee before the death of a Participant, if valid, shall control. 5.4.2. Failure to Designate. If there is no valid Beneficiary designation on file with the Company, or if all Beneficiaries designated by a Participant have predeceased the Participant, the benefits payable under the Plan by reason of the death of the Participant shall be paid to the Participant's spouse, if living; if the Participant does not leave a surviving spouse, to the Participant's issue by right of representation; or, if there are no such issue then living, to the Participant's estate. If there are benefits remaining unpaid at the death of a sole Beneficiary (who died after the Participant) under the Plan and if no successor Beneficiary has been designated, the remaining balance of the benefits under the Plan shall be paid to the deceased Beneficiary's estate, unless the Beneficiary designation form provides to the contrary. If there are benefits remaining unpaid at the death of a Beneficiary (who died after the Participant) who is one of multiple concurrent Beneficiaries, such remaining benefits shall be paid proportionally to the surviving Beneficiaries, unless the Beneficiary designation form provides to the contrary. 21 5.4.3. Death After Benefit Commencement. If a Participant dies after benefits have commenced pursuant to Section 5.2, the Participant's Account balance(s), if any, shall be paid to the Participant's Beneficiary in the same manner that benefits would have been paid to the Participant had the Participant survived. The Committee may, at its sole discretion, accelerate the timing of payments to the Beneficiary. Any Beneficiary may request such acceleration in writing to the Committee. 5.4.4. Death Before Benefit Commencement. If the Participant dies before distribution has commenced to the Participant, distribution to the Beneficiary shall be in the form of a lump sum. Distribution shall be made as soon as administratively practicable following the Participant's death. 5.4.5. Marital Deduction. If any benefits are payable under the Plan to the surviving spouse of a deceased Participant, the estate of the Participant's spouse shall be entitled to all remaining benefits, if any, at the spouse's death, unless specifically directed to the contrary by an effective Beneficiary designation. Section 5.5. Minimum Amount and Frequency of Payments. Notwithstanding anything in this Article 5 to the contrary, the Committee may adjust the length of the distribution period under this Article 5 in order to assure that any monthly installment is not less than $500. If the value of all Accounts at the date of initial distribution is less than $30,000, then, notwithstanding any other provision of the Plan to the contrary, the Committee may pay the Account in a lump sum. Section 5.6. Section 162(m) of the Code. Notwithstanding anything to the contrary in this Plan, a Participant's Employer may defer payment of any amounts otherwise required to be 22 paid under this Plan in order to preserve the deduction for such payment under Section 162(m) of the Code. Section 5.7. Acceleration of Distributions. If the Internal Revenue Service determines that a Participant or Beneficiary has received an economic benefit or is in constructive receipt of a benefit under the Plan and has made a final assessment of an income tax deficiency with respect to such benefit or if a final judicial determination has been entered that an income tax deficiency exists, the Committee shall distribute to such Participant an amount equal to the taxable income recognized. Section 5.8. Withdrawals. 5.8.1. Hardship Withdrawal. Upon the application of any Participant, the Committee may permit such Participant to withdraw some or all of the amount in one or more of the Participant's Accounts. A Participant must provide the Committee with a written petition of the intent to withdraw from the Participant's Account at least 60 days (or such shorter time as permitted by the Committee in its discretion) before the date of withdrawal. No withdrawal shall be made under the provisions of this Section except for the purpose of enabling a Participant to meet immediate needs created by a severe financial hardship to the Participant or resulting from a sudden and unexpected illness or accident of the Participant or of a dependent of the Participant, loss of the Participant's property due to casualty, the Participant's Disability, or other similar extraordinary and unforeseeable circumstances arising as a result of events beyond the control of the Participant. The circumstances that will constitute a severe financial hardship will depend upon the facts of each case, but, in any case, payment may not be made to the extent that such hardship is or may be relieved: (a) through reimbursement or compensation through 23 insurance or otherwise; (b) by liquidation of the Participant's assets, to the extent such liquidation would not itself cause a severe financial hardship; or (c) by cessation of deferrals under the Plan, to the extent permitted under the terms of the Plan. If a withdrawal is permitted, the amount of the withdrawal shall be distributed to the Participant in a lump sum as soon as is administratively practicable following the requested withdrawal date. In addition, (a) the deferral election of the Participant for the remainder of the Plan Year shall be terminated and (b) the Participant may not enter into a new deferral election until a Plan Year that begins at least twelve months following the date of the withdrawal. 5.8.2. Early Distribution. Upon the application of any Participant made after the Participant's Retirement, the Committee shall permit such Participant to receive a distribution of some or all of the amounts in an Account before the time otherwise specified in the Plan for reasons other than financial hardship. Provided, however, that a request for a distribution of 75% or more of an Account shall be deemed to be and shall be treated as a request for a distribution of 100% of the Account. A Participant must give a written petition of the Participant's intent to receive such a distribution at least 60 days (or such shorter time as permitted by the Committee in its discretion) before the date of the distribution. Such a request may be made no more than once during any Plan Year. If a Participant elects to receive such a distribution a penalty shall be imposed such that the amount of the requested distribution shall be reduced by 10% (5% if the request is made within the 24-month period following a Change in Control), which reduction shall be permanently forfeited by the Participant to the Company. 24 Section 5.9. Distributions on Plan Termination. Notwithstanding anything in Article 5 to the contrary, if the Plan is terminated, distributions shall be made in accordance with Section 8.2. Section 5.10. Claims Procedure. 5.10.1. Initial Claim for Benefits. The following shall apply with respect to claims of Participants for benefits under the Plan. The Committee shall give notice to a Participant within 90 days of the Participant's written application for benefits of the Participant's eligibility or noneligibility for benefits under the Plan. If the Committee determines that a Participant is not eligible for benefits or full benefits, the notice shall set forth (i) the specific reasons for such denial, (ii) a specific reference to the provision of the Plan on which the denial is based, (iii) a description of any additional information or material necessary for the claimant to perfect the claim, and a description of why it is needed, and (iv) an explanation of the Plan's claims review procedure and other appropriate information as to the steps to be taken if the Participant wishes to have the claim reviewed. If the Committee determines that there are special circumstances requiring additional time to make a decision, the Committee shall give notice to the Participant of the special circumstances and the date by which a decision is expected to be made, and may extend the time for up to an additional 90-day period. 5.10.2. Appeal of Claim Denial. If a Participant is determined by the Committee to be not eligible for benefits, or if the Participant believes that the Participant is entitled to greater or different benefits, the Participant shall have the opportunity to have the claim reviewed by filing a petition for review within 60 days after the Participant has been given the notice issued by the Committee. If there is no Trust in place with respect to the Participant's benefit, or if there is a Trust, but the Trustee has not agreed to determine 25 appeals from denials of claims for benefits under the Plan, then the petition shall be filed with the Committee. If there is a Trust in place with respect to the Participant's benefit and if the Trustee has agreed to determine appeals from denials of claims for benefits under the Plan, then the petition shall be filed with the Trustee of the Trust. A petition shall state the specific reasons the Participant believes that the Participant is entitled to benefits or greater or different benefits. Within 60 days after the petition has been filed, the Committee or the Trustee, as the case may be, shall afford the Participant an opportunity to present the Participant's position to the Committee or the Trustee, as the case may be, in writing, and the Participant shall have the right to review pertinent documents. The Committee or the Trustee, as the case may be, shall give notice to the Participant of its decision in writing within said 60-day period, stating specifically the basis of the decision written in a manner calculated to be understood by the Participant and the specific provisions of the Plan on which the decision is based. If because of special circumstances, the 60-day period is not sufficient, the decision may be deferred for up to another 60-day period at the election of the Committee or the Trustee, as the case may be, but notice of this deferral shall be given to the Participant. ARTICLE 6. FUNDING Section 6.1. Source of Benefits. All benefits under the Plan shall be paid when due by the Company out of its assets or from the Trust. Section 6.2. No Claim on Specific Assets. No Participant shall be deemed to have, by virtue of being a Participant in the Plan, any claim on any specific assets of the Company such that the Participant would be subject to income taxation on the Participant's benefits under the 26 Plan before distribution. The rights of Participants and Beneficiaries to benefits to which they are otherwise entitled under the Plan shall be those of an unsecured general creditor of the Company. ARTICLE 7. ADMINISTRATION AND FINANCES Section 7.1. Administration. The Plan shall be administered by the Committee. The Company shall bear all administrative costs of the Plan other than those specifically charged to a Participant or Beneficiary. Section 7.2. Powers of Committee. In addition to the other powers granted under the Plan, the Committee shall have all powers necessary to administer the Plan, including, without limitation, powers (i) to interpret the provisions of the Plan; (ii) to establish and revise the method of accounting for the Plan; (iii) to maintain the Accounts; (iv) to determine Crediting Rates for the Accounts; (v) to establish rules for the administration of the Plan; and (vi) to prescribe any forms required to administer the Plan. Section 7.3. Actions of the Committee. Except as modified by the Board, the Committee (including any person or entity to whom the Committee has delegated duties, responsibilities or authority, to the extent of such delegation) has total and complete discretionary authority to determine conclusively for all parties all questions arising in the administration of the Plan, to interpret and construe the terms of the Plan, and to determine all questions of eligibility and status of employees, Participants and Beneficiaries under the Plan and their respective interests. Subject to the claims procedures of Section 5.10, all determinations, interpretations, rules and decisions of the Committee (including those made or established by any person or entity to whom the Committee has delegated duties, responsibilities or authority, if made or established pursuant to such delegation) are conclusive and binding upon all persons having or claiming to 27 have any interest or right under the Plan. A Participant or Beneficiary is entitled to benefits under this Plan only if the Committee in its discretion has determined the Participant or Beneficiary to be so entitled. Section 7.4. Delegation. The Committee, or any officer designated by the Committee, shall have the power to delegate specific duties and responsibilities to officers or other employees of the Company or other individuals or entities. Any delegation may be rescinded by the Committee at any time. Each person or entity to whom a duty or responsibility has been delegated shall be responsible for the exercise of such duty or responsibility and shall not be responsible for any act or failure to act of any other person or entity. Section 7.5. Reports and Records. The Committee, and those to whom the Committee has delegated duties under the Plan, shall keep records of all their proceedings and actions and shall maintain books of account, records, and other data as shall be necessary for the proper administration of the Plan and for compliance with applicable law. ARTICLE 8. AMENDMENTS AND TERMINATION. Section 8.1. Amendments. The Company, by action of the Board, or the Committee to the extent authorized by the Board, may amend the Plan, in whole or in part, at any time and from time to time. Provided, however, that for a period of 24 months following a Change in Control, no amendment shall be effective without the approval of a majority of the Participants in the Plan. Any amendment shall be filed with the Plan documents. No amendment, however, may be effective to eliminate or reduce any Account balance, determined as of the date of such amendment, of any Participant or of any Beneficiary then eligible for benefits, without such Participant's or Beneficiary's consent. 28 Section 8.2. Termination. The Company reserves the right to terminate the Plan at any time by action of the Board. Provided, however, that for a period of 24 months following a Change in Control, no termination shall be effective without the approval of a majority of the Participants in the Plan. Upon termination of the Plan, all deferrals and Company Contributions will cease and no future deferrals or Company Contributions will be made. Termination of the Plan shall not operate to eliminate or reduce any Account balance, determined as of the date of such termination, of any Participant or of any Beneficiary then eligible for benefits, without such Participant's or Beneficiary's consent. If the Plan is terminated, payments from the Accounts of all Participants and Beneficiaries shall be made as soon as administratively practicable following the termination in a lump sum or, in the discretion of the Company, in installments over a period of no more than three years, commencing within 90 days of the date of termination of the Plan. Provided, however, that if the termination occurs within 24 months following a Change in Control, distribution must be made in a lump sum as soon as administratively practicable (but in no event longer than 90 days) following the termination. Accounts shall be credited with earnings during the payment period in accordance with Section 4.6 and 5.3. ARTICLE 9. MISCELLANEOUS Section 9.1. No Guarantee of Employment. Neither the adoption and maintenance of the Plan nor the execution by the Company of a deferral or Account election with any Participant shall be deemed to be a contract of employment between the Company or any Affiliate and any Participant. Nothing contained herein shall give any Participant the right to be retained in the employ of the Company or any Affiliate or to interfere with the right of the Company or any Affiliate to discharge any Participant at any time, nor shall it give the Company or any Affiliate 29 the right to require any Participant to remain in its employ or to interfere with the Participant's right to terminate the Participant's employment at any time. Section 9.2. Release. Any payment of benefits to or for the benefit of a Participant or a Participant's Beneficiaries that is made in good faith by the Company in accordance with the Company's interpretation of its obligations hereunder shall be in full satisfaction of all claims against the Company or an Affiliate for benefits under this Plan to the extent of such payment. Section 9.3. Notices. Any notice or communication permitted or required under the Plan shall be in writing and shall be delivered personally, or sent by registered or certified mail, return receipt requested, postage prepaid, or sent by nationally recognized overnight carrier, postage prepaid, or sent by facsimile transmission to the principal office of the Company, if to the Company, or to the address last shown on the records of the Company or an Affiliate, if to a Participant or Beneficiary. Such notice or communication shall be deemed given (a) when delivered if personally delivered; (b) five mailing days after having been placed in the mail, if delivered by registered or certified mail; (c) the business day after having been placed with a nationally recognized overnight carrier, if delivered by nationally recognized overnight carrier, and (d) the business day after transmittal when transmitted with electronic confirmation of receipt, if transmitted by facsimile. Any party may change the address or facsimile number to which notices or communications are to be sent to it by giving notice of such change in the manner herein provided for giving notice. Section 9.4. Nonalienation. No benefit payable at any time under this Plan shall be subject in any manner to alienation, sale, transfer, assignment, pledge, levy, attachment, or encumbrance of any kind by any Participant or Beneficiary. 30 Section 9.5. Tax Liability. The Company may withhold or direct the trustee of the Trust to withhold from any payment of benefits (or from any other amounts to be paid to the Participant or Beneficiaries) such amounts as the Company determines are reasonably necessary to pay any taxes (and interest thereon) required to be withheld or for which the trustee of the Trust may become liable under applicable law. The Company may also forward or direct the trustee of the Trust to forward to the appropriate taxing authority any amounts required to be paid by the Company or the Trust under the preceding sentence. Section 9.6. Parachute Payments. No gross up or other recalculations of amounts owed under this Plan shall be made to avoid excess parachute payments under Section 280G of the Code or excise tax liability under Section 4999 of the Code. Section 9.7. Indemnification. The Company shall indemnify and defend to the fullest extent permitted by law any employee or former employee serving or formerly serving as a member of the Committee against all liabilities, damages, costs and expenses (including attorneys' fees and amounts paid in settlement of any claims approved by the Company) occasioned by any act or omission to act in connection with the Plan, if such act or omission is in good faith. Section 9.8. Captions. Article and section headings and captions are provided for purposes of reference and convenience only and shall not be relied upon to construe, define, modify, limit, or extend the scope of any provision of the Plan.
