ARTICLE 7. RIGHT TO BENEFITS.

7.01. Normal or Early Retirement. If provided by the Employer in Section 1.07(d), each Participant who attains his Normal Retirement Age or Early Retirement Age will have a nonforfeitable interest in his Account in accordance with the vesting schedule elected in Section 1.07. If a Participant retires on or after attainment of Normal or Early Retirement Age, such retirement is referred to as a normal retirement. On or after his normal retirement, the balance of the Participant's Account, plus any amounts thereafter credited to his Account, subject to the provisions of Section 7.06, will be distributed to him in accordance with Article 8.

If provided by the Employer in Section 1.06, a Participant who separates from service before satisfying the age requirements for early retirement, but has satisfied the service requirement will be entitled to the distribution of his Account, subject to the provisions of Section 7.06, in accordance with Article 8, upon satisfaction of such age requirement.

7.02. DEATH. If a Participant dies before the distribution of his Account has commenced, or before such distribution has been completed, his Account shall become vested in accordance with the vesting schedule elected in Section 1.07 and his designated Beneficiary or Beneficiaries will be entitled to receive the balance or remaining balance of his Account, plus any amounts thereafter credited to his Account, subject to the provisions of Section 7.06. Distribution to the Beneficiary or Beneficiaries will be made in accordance with Article 8.

4/ll/94

A participant may designate a Beneficiary or Beneficiaries, or change any prior designation of Beneficiary or Beneficiaries by giving notice to the Administrator on a form designated by the Administrator. If more than one person is designated as the Beneficiary, their respective interests shall be as indicated on the designation form.

A copy of the death notice or other sufficient documentation must be filed with and approved by the Administrator. If upon the death of the Participant there is, in the opinion of the Administrator, no designated Beneficiary for part or all of the Participant's Account, such amount will be paid to his surviving spouse or, if none, to his estate (such spouse or estate shall be deemed to be the Beneficiary for purposes of the Plan). If a Beneficiary dies after benefits to such Beneficiary have commenced, but before they have been completed, and, in the opinion of the Administrator, no person has been designated to receive such remaining benefits, then such benefits shall be paid to the deceased Beneficiary's estate.

7.03. OTHER TERMINATION OF EMPLOYMENT. If provided by the Employer in Section 1.06, if a Participant terminates his employment for any reason other than death or normal retirement, he will be entitled to a termination benefit equal to (i) the vested percentage(s) of the value of the Matching Contributions to his Account, as adjusted for income, expense, gain, or loss, such percentage(s) determined in accordance with the vesting schedule(s) selected by the Employer in Section 1.07, and (ii) the value of the Deferral Contributions to his Account as adjusted for income, expense, gain or lose. The amount payable under this
Section 7.03 will be subject to the provisions of Section 7.06 and will be distributed in accordance with Article 8.

7.04. SEPARATE ACCOUNT. If a distribution from a Participant's Account has been made to him at a time when he has a nonforfeitable right to less than 100 percent of his Account, the vesting schedule in Section 1.07 will thereafter apply only to amounts in his Account attributable to Matching Contributions allocated after such distribution. The balance of his Account immediately after such distribution will be transferred to a separate account which will be maintained for the purpose of determining his interest therein according to the following provisions.

At any relevant time prior to a forfeiture of any portion thereof under
Section 7.05, a Participant's nonforfeitable interest in his Account held in a separate account described in the preceding paragraph will be equal to P(AB + (RxD))-(RxD), where P is the nonforfeitable percentage at the relevant time determined under Section 7.05; AB is the account balance of the separate account at the relevant time; D is the amount of the distribution; and R is the ratio of the account balance at the relevant time to the account balance after distribution. Following a forfeiture of any portion of such separate account under Section 7.05 below, any balance in the Participant's separate account will remain fully vested and nonforfeitable.

4/11/94

7.05. FORFEITURES. If a Participant terminates his employment, any portion of his Account (including any amounts credited after his termination of employment) not payable to him under Section 7.03 will be forfeited by him. For purposes of this paragraph, if the value of a Participant's vested account balance is zero, the Participant shall be deemed to have received a distribution of his veered interest immediately following termination of employment. Such forfeitures will be applied to reduce the contributions of the Employer under the Plan (or administrative expenses of the Plan).

7.06. ADJUSTMENT FOR INVESTMENT EXPERIENCE. If any distribution under this Article 7 is not made in a single payment, the amount remaining in the Account after the distribution will be subject to adjustment until distributed to reflect the income and gain or loss on the investments in which such amount is treated as invested and any expenses properly charged under the Plan and Trust to such amounts.

7.07. HARDSHIP WITHDRAWALS. Subject to the provisions of Article 8, a Participant shall not be permitted to withdraw his Account (and earnings thereon) prior to retirement or termination of employment, except if permitted under Section 1.09, a Participant may apply to the Administrator to withdraw, some or all of his Account if such withdrawal is made on account of a hardship as determined by the Employer.

7.08. ADDED AT ADOPTION. See Exhibit A.

Article 8. DISTRIBUTION OF BENEFITS PAYABLE AFTER TERMINATION IF SERVICE.

8.01. DISTRIBUTION OF BENEFITS TO PARTICIPANTS AND BENEFICIARIES.

(a) Distributions under the Plan to a Participant or to the Beneficiary of the participant shall be made in a lump sum in cash or, if elected by the Employer in Section 1.10 and specified in the Participant's deferral election, under a systematic withdrawal plan (installment(s)) not exceeding 10 years upon retirement, death or other termination of employment.

(b Distributions under a systematic withdrawal plan must be made in substantially equal annual, or more frequent, installments, in cash, over a period certain which does not extend 10 years. The period certain specified in a Participant's first deferral election specifying distribution under a systematic withdrawal plan shall apply to all subsequent elections of distributions under a systematic withdrawal plan made by the Participant.

8.02. DETERMINATION OF METHOD OF DISTRIBUTION. The Participant will determine the method of distribution of benefit, to himself and the method of distribution to his Beneficiary.

4/11/94

8.03. NOTICE TO TRUSTEE. The Administrator will notify the Trustee in writing whenever any Participant or Beneficiary is entitled to receive benefits under the Plan. The Administrator's notice shall indicate the form, amount and frequency of benefits that such Participant or Beneficiary shall receive.

11.02. NONDISCRIMINATORY EXERCISE OF AUTHORITY. Whenever, in the administration of the Plan, any discretionary action by the Administrator is required, the Administrator shall exercise its authority in a nondiscriminatory manner so that all persons similarly situated will receive substantially the same treatment. See Exhibit B for provision added at adoption of Plan.

11.03. CLAIMS AND REVIEW PROCEDURES.

(a) CLAIMS PROCEDURE. If any person believes he is being denied any rights or benefits under the Plan, such person may file a claim in writing with the Administrator. If any such claim is wholly or partially denied, the Administrator will notify such person of its decision in writing. Such notification will contain (i) specific reasons for the denial, (ii) specific reference to pertinent Plan provisions, (iii) a description of any additional material or information necessary for such person to perfect such claim and an explanation of why such material or information is necessary, and (iv) information as to the steps to be taken if the person wishes to submit a request for review. Such notification will be given within 90 days after the claim is received by the Administrator (or within 180 days, if special circumstances require an extension of time for processing the claim, and if written notice of such extension and circumstances is given to such person within the initial 90-day period). If such notification is not given within such period, the claim will be considered denied as of the last day of such period and such person may request a review of his claim.

(b) REVIEW PROCEDURE. Within 60 days after the date on which a person receives a written notice of a denied claim (or, if applicable, within 60 days after the date on which such denial is considered to have occurred), such person (or his duly authorized representative) may (i) file a written request with the Administrator for a review of his denied claim and of pertinent documents and (ii) submit written issues and comments to the Administrator. The Administrator will notify such person of its decision in writing. Such notification will be written in a manner calculated to be understood by such person and will contain specific reasons for the decision as well as specific references to pertinent Plan provisions. The decision on review will be made within 60 days after the request for review is received by the Administrator (or within 120 days, if special circumstances require an extension of time for processing the request, such as an election by the Administrator to hold a hearing, and if written notice of such extension and circumstances is given to such person within the initial 60-day period). if the decision on review is not made within such period, the claim will be considered denied.

4/11/94

11.04. COSTS OF ADMINISTRATION. Unless some or all cost, and expense are paid by the Employer, all reasonable coats and expenses (including legal, accounting, and employee communication fees) incurred by the Administrator and the Trustee in administering the Plan and Trust will be paid first from the forfeitures (if any) resulting under Section 7.05, then from the remaining Trust Fund. All such coats and expenses paid from the Trust Fund will, unless allocable to the Accounts of particular Participants, be charged against the Accounts of all Participant, on a prorata basis or in such other reasonable manner as may be directed by the Employer.

EXHIBIT A

7.08. UNSCHEDULED WITHDRAWAL RIGHT. A Participant may request an unscheduled withdrawal of all or any portion of the Account (to the extent vested) before or after his termination of employment by written notice to the Employer; provided that, the amount distributable from such Participant's Account will be reduced by ten percent (10%). This reduction will be forfeited and used to pay expenses of the Plan and Trust. If a Participant elects an unscheduled withdrawal under this Section prior to termination of employment, the Participant shall not be permitted to elect Deferral Contributions, pursuant to Section 4.01, for a period of twenty-four (24) months following the date of such withdrawal.

EXHIBIT B

11.02. The interpretation and construction of any provision of the Plan and the exercise of any discretion granted hereunder to the Administrator shall be final and binding on the Participants, their dependents and all other interested persons.
