To the extent the foregoing calculation does not result in a whole number of Shares, the fractional Share shall be paid in cash. In the absence of an election, the annual retainer shall be paid in cash. 5.2 TIME OF PAYMENT. In the absence of an election pursuant to Section 6.1, the annual retainer of an Eligible Director, shall be paid in cash or Shares, as elected by the Director pursuant to Section 5.1, on each Payment Date.

ARTICLE VII PAYMENT OF DEFERRED AMOUNTS 7.1 PAYMENT OF ACCOUNTS. No payments may be made from a Participant's Accounts until the Participant terminates service as an Eligible Director. Upon termination of the Participant's service as an Eligible Director for any reason, including death, the Participant's Accounts shall be paid to the Director or the Director's Beneficiary, as the case may be, as soon as administratively possible after Participant ceases to be an Eligible Director.

No amendment, modification or termination of the Plan shall, without the consent of a Participant, reduce the benefits that a Participant has already accrued under the Plan. 8.3 FUTURE DIRECTOR TERMS. Nothing in the Plan, nor any action taken under the Plan, shall be construed as giving any Participant a right to continue as a Director or require the Company to nominate or cause the nomination of a Participant for a future term as a Director. 8.4 PARTICIPANT'S RIGHTS UNSECURED. The right of any Participant to receive payment of deferred amounts under the provisions of the Plan shall be an unsecured claim against the general assets of the Company.
