Such notification must be on the form and in accordance with the procedures established by the Committee.

Such designation must provide reasonable detail regarding the identity of the authorized representative. A Participant or beneficiary may have only one authorized representative at any time.

(c) Claim Denial Procedure. If a claim is wholly or partially denied, the Committee shall notify the Claimant within a reasonable period of time, but not later than 90 days after receipt of the claim, unless the Committee determines that special circumstances require an extension of time for processing the claim. If the Committee determines that an extension of time for processing is required, written notice of the extension shall be furnished to the Claimant prior to the termination of the initial 90-day period. In no event shall such extension exceed a period of 180 days from receipt of the claim.

(d) Appeal Procedure. In the case of an adverse benefit determination, the Claimant or his representative shall have the opportunity to appeal to the Board of Directors for review thereof by requesting such review in writing to the Committee within 60 days of receipt of notification of the denial. Failure to submit a proper application for appeal within such 60 day period will cause such claim to be permanently denied. The Claimant or his representative shall be provided, upon request and free of charge, reasonable access to, and copies of, all documents, records and other information relevant to the claim. The Claimant or his representative shall also be provided the opportunity to submit written comments, documents, records and other information relating to the claim for benefits. The Committee shall review the appeal taking into

- 12 -

account all comments, documents, records and other information submitted by the Claimant or his representative relating to the claim, without regard to whether such information was submitted or considered in the initial benefit determination.

(e) Decision on Appeal. The Committee shall notify a Claimant of its decision on appeal within a reasonable period of time, but not later than 60 days after receipt of the Claimant’s request for review, unless the Committee determines that special circumstances require an extension of time for processing the appeal. If the Committee determines that an extension of time for processing is required, written notice of the extension shall be furnished to the Claimant prior to the termination of the initial 60-day period. In no event shall such extension exceed a period of 60 days from the end of the initial period. The extension notice shall indicate: (i) the special circumstances necessitating the extension and (ii) the date by which the Committee expects to render a benefit determination. An adverse benefit decision on appeal shall be written in a manner calculated to be understood by the Claimant and shall set forth: (i) the specific reason or reasons for the adverse determination, (ii) the specific reference to the Plan provisions on which the denial is based, (iii) a statement that the Claimant is entitled to receive, upon request and free of charge, reasonable access to and copies of all documents, records, and other information relevant to the Claimant’s claim, and (iv) a statement of the Claimant’s right to bring a legal action.

(f) Litigation. In order to operate and administer the claims procedure in a timely and efficient manner, any Claimant whose appeal with respect to a claim for benefits has been denied, and who desires to commence a legal action with respect to such claim, must commence such action in a court of competent jurisdiction within 90 days of receipt of notification of such denial. Failure to file such action by the prescribed time will forever bar the commencement of such actions.

12. Funding of Plan. This Plan is an unfunded arrangement. The right of any Participant or beneficiary to receive future payments under the provisions of the Plan shall be an unsecured claim against the general assets of the Company. Any trust, and any other fund, account, contract or arrangement that the Company chooses to establish for the future payment of benefits under this Plan to a Participant or beneficiary shall remain part of the Company’s general assets and no person claiming payments under the Plan shall have any right, title or interest in or to any such trust, fund, account, contract or arrangement.
