converting an Incentive Stock Option to a Nonstatutory Stock Option, provided that the Participant&#146;s consent to such action shall be required (a) if such action would terminate, or reduce the number of shares issuable under, an Option, unless
any time period relating to the exercise of such Option or the eliminated portion, as the case may be, is accelerated before such termination or reduction, in which case the Committee may provide for the Participant to receive cash or other property
equal to the net value that would be received upon exercise of the terminated Option or the eliminated portion, as the case may be, and (b) in any other case, unless the Committee determines that the action, taking into account any related action,
would not materially and adversely affect the Participant. The Committee shall not, without further approval of the stockholders of the Company, authorize the amendment of any outstanding Option to reduce the exercise price. Furthermore, no Option
shall be canceled and replaced with Options having a lower exercise price without approval of the stockholders of the Company. </FONT></P>
