from time to time on or prior to the Expiration Date of this Option, the
Optionee may give written notice to the Company of his or her election to
purchase some or all of the vested Option Shares purchasable at the time of such
notice. This notice shall specify the number of Option Shares to be purchased.

      Payment of the purchase price for the Option Shares may be made by one or
more of the following methods: (i) in cash, by certified or bank check or other
instrument acceptable to the Administrator; (ii) in the form of shares of Stock
that are not then subject to restrictions under any Company plan and that have
been held by the Optionee for at least six months; (iii) by the Optionee
delivering to the Company a properly executed exercise notice together with
irrevocable instructions to a broker to promptly deliver to the Company cash or
a check payable and acceptable to the Company to pay the option purchase price,
provided that in the event the Optionee chooses to pay the option purchase price

and enter into such agreements of indemnity and other agreements as the
Administrator shall prescribe as a condition of such payment procedure; or (iv)
a combination of (i), (ii) and (iii) above. Payment instruments will be received

      The delivery of certificates representing the Option Shares will be

Option Shares, as set forth above and any agreement, statement or other evidence

Stock Option shall be issued and delivered to the Optionee upon compliance to
the satisfaction of the Administrator with all requirements under applicable
laws or regulations in connection with such issuance and with the requirements
hereof and of the Plan. The determination of the Administrator as to such
compliance shall be final and binding on the Optionee. The Optionee shall not be
deemed to be the holder of the shares subject to this Stock Option, or to have
any of the rights of a holder, unless and until this Stock Option shall have
been exercised pursuant to the terms hereof, the Company shall have issued and
delivered the shares to the Optionee, and the Optionee's name shall have been
entered as the stockholder of record on the books of the Company. Thereupon, the
Optionee shall have full voting, dividend and other ownership rights with
respect to such shares of Stock.

portion of this Stock Option shall be exercisable after the Expiration Date

reason other than Cause or death, any Stock Option held by the Optionee may be
exercised for a period of one (1) month from the date of termination or until
the Expiration Date, if earlier.

respect to continuance as a Director.
