VI.2 The Plan shall be administered by the Committee who shall be appointed by the Board of Directors of the Corporation. The members of the Committee shall not receive compensation with respect to their services for the Committee. The members of the Committee shall serve without bond or security for the performance of their duties hereunder unless applicable law makes the furnishing of such bond or security mandatory or unless required by the Corporation. Any member of the Committee may resign by delivering his written resignation to the Corporation and to the other members of the Committee.

VI.3 The Committee shall perform any act which the Plan authorizes expressed by a vote at a meeting or in a writing signed by a majority of its members without a meeting. The Committee may, by a writing signed by a majority of its members, appoint any member of the Committee to act on behalf of the Committee. Any person who is a member of the Committee shall not vote or decide upon any matter relating solely to himself or vote in any case in which his individual right or claim to any benefit under the Plan is particularly involved. If, in any matter or case in which a person is so disqualified to act, the remaining persons constituting the Committee cannot resolve such matter or case, the Board will appoint a temporary substitute to exercise all the powers of the disqualified person concerning the matter or case in which he is disqualified.

VI.4 The Committee may designate in writing other persons to carry out its responsibilities under the Plan, and may remove any person designated to carry out its responsibilities under the Plan by notice in writing to that person. The Committee may employ persons to render advice with regard to any of its responsibilities. All of the usual and reasonable expenses of the Committee shall be paid by the Corporation. The Corporation shall indemnify and hold harmless each member of the Committee from and against any and all claims and expenses (including, without limitation attorney’s fees and related costs), in connection with the performance by such member of his duties in that capacity, other than any of the foregoing arising in connection with the willful neglect or willful misconduct of the person so acting.

VI.5 The Committee shall establish rules, not contrary to the provisions of the plan, the administration of the Plan and the transaction of its business. The Committee shall determine the eligibility of any individual to participate in the Plan, shall interpret the Plan in its sole and absolute discretion, and shall determine all questions arising in the administration interpretation and application of the Plan. A.11 determinations of the Committee shall be final, conclusive and binding on all employees, participants and Beneficiaries.

VI.6 Any action to be taken hereunder by the Corporation shall be taken by resolution adopted by the Board or an executive committee thereof; provided, however, that by resolution, the Board or an executive committee thereof may delegate to any officer of the Corporation the authority to take any actions hereunder, other than the power to amend or terminate the Plan.

VI.7 Each Participant will be issued a participation agreement under the Plan which will specify, as to that Participant; the amount of Company contributions to be made to the Plan on behalf of the Participant, the Participant’s vesting schedule, and any other conditions or benefits the Committee deems in its sole and absolute discretion to be appropriate.

ARTICLE VII

CLAIM REVIEW PROCEDURE

VII.1 In the event that a Participant or Beneficiary is denied a claim for benefits under this Plan (the “Claimant”), the Committee shall provide to the Claimant written notice of the denial which shall set forth:

That any appeal the Claimant wishes to make of the adverse determination must be in writing to the Committee within sixty (60) days after receipt of the Committee’s notice of denial of benefits. The Committee’s notice must further advise the Claimant that his failure to appeal the action to the Committee in writing within the sixty (60) day period will render the Committee’s determination final, binding, and conclusive.

VII.2 If the Claimant should appeal to the Committee, he, or his duly authorized representative, may submit, in writing, whatever issues and comments he, or his duly authorized representative, feels are pertinent. The Committee shall re-examine all facts related to the appeal and make a final determination as to whether the denial of benefits is justified under the circumstances. The Committee shall advise the Claimant in writing of its decision on his appeal, the specific reasons for the decision, and the specific Plan provisions on which the decision is based. The notice of the decision shall be given within sixty (60) days of the Claimant’s written request for review, unless special circumstances (such as hearing) would make the rendering of a decision within sixty (60) day period infeasible, but in no event shall the Committee render a decision regarding the denial of a claim later than 120 days after its receipt of a request for review. If an extension of time for review is required because of special circumstances, written notice of the extension shall be furnished to the Claimant prior to the date the extension period commences. The Committee’s notice of denial of benefits shall identify the address to which the Claimant may forward his appeal.

ARTICLE VIII

LIMITATION OF RIGHTS

The establishment of this Plan shall not be construed as giving to any Participant, employee of the Corporation or any person whomsoever, any legal, equitable or other -rights against the Corporation, or its officers, directors, agents or shareholders, or as giving to any Participant or Beneficiary any equity or other interest in the assets or business of the Corporation or shares of Corporation stock or as giving any employee the right to be retained in the employment of the Corporation.

LIMITATION OF ASSIGNMENT AND PAYMENTS TO

LEGALLY INCOMPETENT DISTRIBUTEE

IX.1 No benefits which shall be payable under the Plan to any person shall be subject in any manner to anticipation, alienation, tale, transfer, assignment, pledge, encumbrance or charge and any attempt to anticipate, alienate, tell, transfer, assign, pledge, encumber, charge or otherwise dispose of the same shall be void.

IX.2 No benefit shall in any manner be subject to the debts, contracts, liabilities, engagements or torts of any person, nor shall it be subject to attachment or legal process for or against any person, except to the extent required by law.

IX.3 Whenever any benefit which shall be payable under the Plan is to be paid to or for the benefit of any person who it then a minor or determined by the Committee, on the basis of qualified medical advice, to be incompetent, the Committee need not require the appointment of a guardian or custodian, but shall be authorized to cause the same to be paid over to the person having custody of the minor or incompetent, or to cause the same to be paid to the minor or incompetent without the intervention of a guardian or custodian, or to cause the same to be paid to a legal guardian or custodian of the minor or incompetent, if one has been appointed, or to cause the same to be used for the benefit of the minor or incompetent.

ARTICLE X

The Corporation reserves the right at any time to amend or terminate the Plan in whole or in part by resolution of the Board; provided, however, that upon a Change in Control, any amendment of the Plan shall, for a period of two (2) years following the effective date of such Change in Control, require the prior written consent of a majority of all Participants and Beneficiaries hereunder, including those Participants and Beneficiaries who, at the time of such amendment, are currently entitled to a benefit hereunder, whether or not employed at such time by the Corporation. No amendment shall have the effect of retroactively changing or depriving Participant or Beneficiaries of rights already accrued under the Plan. In the event that the Corporation shall change its name, the Plan shall be deemed to be amended to reflect the name change without further action of the Corporation,

and the language of the Plan shall be changed accordingly. Notwithstanding any other provision hereunder to the contrary, upon termination of the plan, the Board shall direct that all vested benefits hereunder will be paid as soon as administratively practicable thereafter, but in no event later that 30 days following such termination.
