a fair market value equal to the cash exercise price of the Stock Option being
exercised, with the fair market value of such stock to be determined in such
appropriate manner as may be provided for by the Committee or as may be required
in order to comply with, or to conform to the requirements of, any applicable
laws or regulations, (iii) by any combination of the payment methods specified
in clauses (i) and (ii) hereof, or (iv) such other methods determined by the

been held by the optionee for at least one year and (ii) at least two years have
elapsed since such prior Incentive Stock Option was granted.

         3. The following sentence is added after the first sentence of Section

defined in section 162(m) of the Internal Revenue Code).

                  IN WITNESS WHEREOF, the foregoing amendment was adopted on the
