(a) An Officer shall be eligible for a normal retirement pension under this Section 5.1 if the Officer terminates service with the Employer on or after such Officer's Normal Retirement Date. (b) An Officer's monthly normal retirement pension is based upon one twelfth (1/12th) of the following formula, based on a single life annuity: three and three-fourths percent (3-3/4%) multiplied by Years of Benefit Service (not in excess of 20) multiplied by Compensation minus the Officer's annual accrued benefit from the Retirement Plan payable as a single life annuity, any other employer's annual retirement pension and the Officer's annual Social Security Benefit. 5.2 Early Retirement Pension. (a) If the Officer terminates service with the Employer on or after such Officer's Early Retirement Date, the Officer shall receive an early retirement pension or a normal retirement pension as provided under this Section 5.2.

If the Officer is eligible to receive a benefit from a previous employer's defined benefit retirement plan, the Officer's benefit under this Plan shall be reduced. The amount of the reduction is equal to the monthly pension benefit the Officer earned from the prior employer's plan payable as a single life annuity at such Officer's retirement date. 5.4 Form of Payment. (a) Benefits under this Plan shall be paid on the Officer's Normal Retirement Date or Early Retirement Date in the form selected by the Officer.

If the Officer terminates service with the Employer and is rehired after commencement of benefits but prior to attaining age sixty-five (65), payment of benefits under this Plan shall cease. Payment of benefits under this Plan shall resume when the Officer again terminates service with the Employer. 5.6 Termination for Cause.

The Spouse shall commence payments on the earliest date that the Officer was eligible to retire. (e) If the Officer dies after the Officer retired and commenced payments, the death benefit payable will be based on the form of payment selected by the Officer. 5.8 Claims Procedure. (a) Filing a Claim. Any Officer or Spouse may file a written claim for a Plan benefit with the Plan Administrator. (b) Notice of Denial of Claim. In the event of a denial or limitation of any benefit or payment due to a claimant, the claimant shall be given a written notification containing specific reasons for the denial or limitation of such claimant's benefit. The written notification shall contain specific reference to the pertinent Plan provisions on which the denial or limitation of his benefit is based. In addition, it shall contain a description of any other material or information necessary for the claimant to perfect a claim and an explanation of why such material or information is necessary. The notification shall further provide appropriate information as to the steps to be taken if the claimant wishes to submit the claim for review. This written notification shall be given to a claimant within ninety (90) days after receipt of the claim by the Plan Administrator unless special circumstances require an extension of time for processing the claim. If such an extension of time is required, written notice of the extension shall be furnished to the claimant prior to the termination of said ninety (90) day period, and such notice shall indicate the special circumstances which make the postponement appropriate. (c) Right of Review. In the event of a denial or limitation of his benefit, the claimant shall be permitted to review pertinent documents and to submit to the Plan Administrator issues and comments in writing. In addition, the claimant may make a written request for a full and fair review of the claim and its denial by the Plan Administrator, provided, however, that such written request is received by the Plan Administrator within sixty (60) days after receipt by the claimant of written notification of the denial or limitation of the claim. The sixty (60) day requirement may be waived by the Plan Administrator in appropriate cases. (d) Decision on Review. A decision shall be rendered by the Plan Administrator within sixty (60) days after the receipt of the request for review, provided that where special circumstances require an extension of time for processing the decision, it may be postponed with written notice to the claimant (prior to the expiration of the initial sixty (60) day period) for an additional sixty (60) days, but in no event shall the decision be rendered more than one hundred twenty (120) days after the receipt of such request for review. Any decision by the Plan Administrator shall be furnished to the claimant in writing and shall set forth the specific reason for the decision and the specific Plan provisions on which the decision is based. (e) Court Action. No Officer or Spouse shall have the right to seek judicial review of a denial of benefits or to bring any action in any court to enforce a claim for benefits prior to filing a claim for benefits or exhausting the rights to review under this Section 5.8. 5.9 Forfeiture of Benefits. Upon the occurrence of the following events, the Officer's benefits under this Plan shall be forfeited and no benefits shall be payable to the Officer under this Plan: (a) as provided in Sections 3.2, 5.2(a), 5.6, and 5.7(a); (b) if the Plan terminates, no further benefits shall be accrued under this Plan. The Officer's Accrued Benefit under this Plan shall be the benefit accrued as of the date the Plan is terminated; (c) if the Officer terminates service with the Employer and begins employment with an employer which the Board of Directors determines to be a competitor of the Employer or with any employer in the utility industry. This limitation does not, however, apply to successors and assigns of Employer. ARTICLE VI - ADMINISTRATION OF PLAN 6.1 Administration.

(c) The Plan Administrator shall receive all claims for benefits by Participants or former Participants. The Plan Administrator shall determine all facts necessary to establish the right of any claimant to benefits and the amount of those benefits under the provisions of the Plan. The Plan Administrator may establish rules and procedures to be followed by claimants in filing claims for benefits, in furnishing and verifying proof necessary to determine age, and in any other matters required to administer the Plan. 6.2 Records. (a) All acts and determination of the Plan Administrator shall be duly recorded. All these records, together with other documents necessary for the administration of the Plan, shall be preserved in the Plan Administrator's custody.

While the Employer intends to maintain this Plan indefinitely, the Employer, through the action of the Board of Directors, reserves the right to amend and/or terminate this Plan at any time for whatever reason it may deem appropriate; provided, however, that any such amendment and/or termination adopted by the Board of Directors or otherwise after the occurrence of any Change in Control shall not be effective against any Participant participating in this Plan on the date of any such Change in Control if such amendment and/or termination would have any adverse effect on the benefit rights and/or entitlements, accrued or potential, of such Participant, when compared to any such benefit rights and/or entitlements as the same existed immediately prior to the adoption of any such amendment and/or termination of this Plan, without the prior express written consent of any such adversely effected Participant. 7.2 Amendments. No amendment to this Plan may be made except by action of a simple majority of the Board of Directors. ARTICLE VIII - MISCELLANEOUS PROVISIONS 8.1 No Employment Rights. Nothing contained in this Plan shall be construed as a contract of employment between the Employer and any Officer or as a right of any Officer to be continued in employment or as a limitation on the right of any Employer to discharge any of its Officers with or without cause. 8.2 Non-alienability. The rights of an Officer to the payment of benefits under this Plan shall not be assigned, transferred, pledged or encumbered, or be subject in any manner to alienation or anticipation. 8.3 Facility of Payment.

Whenever possible, each provision of the Plan shall be interpreted in such manner as to be effective and valid under applicable law, but if any provision of the Plan shall be held to be prohibited by or invalid under applicable law, then such provision shall be deemed to be amended to accomplish the objectives of the provision as originally written to the fullest extent permitted by law and all other provisions of the Plan shall remain in full force and effect. Such provision shall be deemed to have been drafted in such manner on the Effective Date. 8.5 Headings. The headings are for convenience of reference only.
