5.Method of Exercise and Payment of Exercise Price.



(a)Subject to the terms and conditions hereof, the option granted under this Option Agreement may be exercised by written notice directed to the Company at its principal place of business setting forth the exact number of shares under this option that the Optionee is purchasing, which may not exceed the number of shares that the Optionee is eligible to purchase under this Option Agreement at the time of such purchase, and enclosing with such written notice a certified or cashier's check or cash, or the equivalent thereof acceptable to the Company, in payment of the full option price for the number of shares specified in such written notice and shall comply with such other reasonable requirements as the Board of Directors of the Company may establish.  Subject to the terms and conditions of this Option Agreement, the Company shall make delivery of such shares within a reasonable period of time after the giving of such notice; provided that if any law or regulation requires the Company to take any action with respect to the shares specified in such notice before the issuance thereof, then the date of delivery of such shares shall be extended for the period necessary to take such action.



(b)The Optionee understands that, on the exercise of this operation (or at the time a sale of the stock acquired by such exercise at a profit would no longer subject Optionee to suit under Section 16(b) of the Securities Exchange Act of 1934, as amended) the excess of the fair market value of the common stock over it option price is taxable remuneration to him subject to federal income tax withholding by the Company.  To facilitate withholding by the Company, if required, Optionee hereby agrees that the exercisability of this option is conditional on Optionee agreeing to such arrangements and taking such actions as the Company determines are appropriate to insure that the amount required to be withheld will be available for payment in money by the Company as required withholding.

For purposes of the preceding sentence, the excess of the aggregate fair market value of the shares subject to this option immediately after the reorganization, consolidation or merger over the aggregate option price of such shares shall not be more than the excess of the aggregate fair market value of all shares subject to this option immediately before such reorganization, consolidation or merger over the aggregate option price of such shares, and the new option or assumption of this option shall not give Optionee additional benefits which he did not have under this option.



To the extent that the foregoing adjustments and determinations relate to the shares of common stock of the Company and/or fair market values of such shares, such
