(b) except in the case of a termination for Cause, vested Options shall remain exercisablethrough the earliest of (i) the normal expiration date, (ii) the 90-day anniversary of the effective date of the Participant’s termination of employment (determined without regard to any statutory or deemed or expresscontractual notice period), (iii) the 180-day anniversary in the case of a Special Termination or a retirement at normal retirement age or later), and (iv) any cancellation pursuant to Section 3.3 or Section 7.1;and

Article VII

Change in Control 

Section 7.1 Accelerated Vesting and Payment. Except as otherwise provided in this Article VII, and unless otherwise provided in the Award Agreement, upon a Change in Control, (a) eachAward that by its terms would otherwise vest based solely on continued employment shall vest in full in connection with such Change in Control and each other Award shall, to the extent it has not or will not by its terms vest before or in connectionwith such Change in Control, be canceled, and (b) the holder of any vested Award (including any Award that vests in connection with such Change in Control) shall be entitled to receive, in complete satisfaction of such Award, a paymentin an amount or with a value equal to the number of shares of Common Stock covered by such vested Award times the excess, if any, of the Change in Control Price over any applicable exercise price or reference price, if any, for such Award.

Section 7.2 Alternative Award. No cancellation, acceleration or other payment shall occur with respect to any Award orclass or type of Award if the Board determines, prior to the occurrence of a Change in Control, that such Award shall be honored or assumed, or new rights substituted therefor following the Change in Control (such honored, assumed or substitutedaward, an “Alternative Award”). 

Section 7.3 Limitation of Benefits. If, whether as a result ofaccelerated vesting, the grant of an Alternative Award or otherwise, a Participant would receive any payment, deemed payment or other benefit as a result of the operation of Section 7.1 or Section 7.2 that, together with any other payment,deemed payment or other benefit a Participant may receive under any other plan, program, policy or arrangement, would constitute an “excess parachute payment” under section 280G of the Code, then, notwithstanding anything in this Plan tothe 

 
5 

contrary, the payments, deemed payments or other benefits such Participant would otherwise receive under Section 7.1 or Section 7.2 shall be reduced to the extent necessary to eliminateany such excess parachute payment and such Participant shall have no further rights or claims with respect thereto. If the preceding sentence would result in a reduction of the payments, deemed payments or other benefits a Participant wouldotherwise receive in more than an immaterial amount, the Company will use its commercially reasonable best efforts to seek the approval of the Company’s shareholders in the manner provided for in section 280G(b)(5) of the Code and theregulations thereunder with respect to such reduced payments or other benefits (if the Company is eligible to do so), so that such payments would not be treated as “parachute payments” for these purposes (and therefore would cease to besubject to reduction pursuant to this Section 7.3). 

Article VIII 

Director Awards 

Director Awards may have such terms as the Board shall determine from time to time, and may be granted as part of the retainer or other fees payable to an Eligible Director or as part of an arrangementthat permits the deferral of payment of such fees, on a mandatory or elective basis, into the right to receive Common Stock and distributions thereon in the future (or a cash payment measured by reference to the value therof).
