        Additional Non-Employee Director Stock Option Agreement Terms


1.      Anything in this Option Agreement or in the Plan to the contrary
        notwithstanding, this Option may not be exercised prior to the date on
        which the Company consummates its public offering of shares under the
        Securities Act of 1933.

2.      Not an Agreement to Continue as a Director. Nothing in this Option
        Agreement shall in any way affect your right to resign from the
        Company's Board of Directors or the Company's right to terminate your
        directorship in accordance with the Articles of Incorporation and
        By-Laws of the Company.

3.      Exercises. For an exercise to be effective, the Company must receive
        from you:

        a)    A written notice signed by you stating the Option Grant Date and
              the number of Option Shares you wish to purchase; and

        b)    Payment for the Option Shares either (i) by cashier's or
              certified check; or (ii) by the surrender of Company common stock
              having a fair market value equal to the purchase price of the
              Option Shares being purchased, all according to the rules and     
              regulations of the Committee.

4.      Option Shares. The Company will not be obligated to deliver any Option
        Shares to you unless:

        a)    Provision acceptable to the Company has been made for the payment
              of any federal, state and local taxes that are due or that are 
              required to be withheld by the Company because of the purchase of
              the Option Shares:

        b)    There has been compliance with all federal and state laws and
              regulations that the Company deems applicable, and all other
              legal matters in connection with the issuance and delivery of
              the Option Shares have been approved by the Company's counsel.

5.      Non-Transferability. Except as expressly otherwise provided in the Plan,
        this Option is exercisable only by you during your lifetime. In
        addition, this Option may not be assigned or transferred except by your
        will or according to the laws of descent and distribution in the
        absence of a will.

6.      Termination of Directorship.

        a)    If the termination of your directorship is by reason of your 
              death or permanent disability, this Option may be exercised as to
              all then unexercised shares by your estate, personal
              representative or beneficiary at any time prior to the
              specified expiration date of the option.
 
        b)    If the termination of your directorship is for any reason other
              than death or permanent disability, any then unexercised portion
              of options granted to such Optionee shall, to the extent not then
              vested, immediately terminate and become void; any portion of an
              option which is vested, but has not been exercised by the
              Optionee shall terminate 180 days after the date the Optionee     
              ceased to be a member of the Board.

7.      Adjustments. As more fully described in the Plan, the number and kind
        of shares issuable under this Option and the Option Price Per Share will
        be adjusted to account for any reorganization, merger, recapitalization,
        or the like that affects the Company's shares.
