effective date of the Plan, shall be made prior to such date. After such date, a
Director may elect to defer all or part of his or her Director's Fees to be
earned on or after the date of the election. For a new Director, the election to
defer Director's Fees earned during his or her initial calendar year of service
shall be made within thirty days following the Director's election or
appointment. Any election to defer shall continue in effect for subsequent
calendar years unless modified or revoked in accordance with section 3.3.

section 3.1(b) to have Director's Fees credited to his or her Cash Deferred Fee
Account, the Company shall credit the Director's Cash Deferred Fee Account with

been paid to the Director if they had not been deferred under the Plan.

     (b)  When a Director elects under section 3.1(b) to have Director's Fees
credited to his or her Stock Deferred Fee Account, the Company shall credit the
Director's Stock Deferred Fee Account with a number of Shares as of the day such
Director's Fees would have been paid to the

                                       4

     5.1 CREDITING OF DIVIDENDS. Each Director with shares credited to his or
her Stock Deferred Fee Account on the record date of a dividend on the Company's
common stock shall be credited on the payment date of the dividend with an
amount determined by the product of the number of shares credited to the
Director's Stock Deferred Fee Account on the dividend record date and the
dividend per share on the Company's common stock. Such amount shall be credited
on the dividend payment date to the Director's Cash Deferred Fee Account, unless
the Director at such lime has a Deferred Fee Agreement in effect which provides
for the deferral of any portion of the Directors fees otherwise payable during
the period which includes the dividend payment date to be credited to the
Director's Stock Defected Fee Account. In such a case, the dividend reinvestment
provisions of Section 5.2 shall apply.

     5.2 DIVIDEND REINVESTMENT SHARES. If the Director has a Deferred Fee
Agreement in effect on the payment date of dividends on the Company's common
stock and such Deferred Fee Agreement provides for any portion of the Director's
fees otherwise payable during the period which includes the dividend payment
date to be credited to the Director's Stock Deferred Fee Account, then on the
dividend payment date the Director's Stock Deferred Fee Account shall be
credited with a number of shares determined by dividing the amount of the
dividends for the Director as determined under Section 5.1 by ninety-seven
percent (97%) of Fair Market Value of the Company's common stock on the dividend
payment date.

Director's Deterred Fee Accounts shall be paid in a lump sum or in installments
in accordance with the terms of such Director's Deferred Fee Agreement. Amounts
credited to a Director's Cash Deferred Fee Account shall bear interest at the
rate specified in Article IV during the installment payout period. Shares
credited to a Director's Stock Deferred Fee Account shall continue to result in
the crediting of additional amounts to a Director's Cash Deferred Fee Account or
additional Shares to the Director's Stock Deferred Fee Account as determined
under Article V during the installment payout period.

     (b) Notwithstanding the foregoing, no payment of shares from a Director's
Stock Deferred Fee Account shall be made unless the Company may validly issue
shares at such time pursuant to all applicable rules and regulations, including
but not limited to corporate law, securities law and stock exchange nobles.  If
Shares may not be issued, subject to compliance with applicable securities laws
requirements, the Fair Market Value of the Shares credited to a Director's Stock
Deferred Fee Account shall be distributed in cash.
