a Qualifying Termination, then (i) the vesting of each Award that vests based on
continued service, and the exercisability of each such Award that is a stock
option, shall be automatically accelerated in full as of the Date of Termination
and (ii) each Award that vests based on performance shall remain outstanding
through the normal performance vesting date thereof (or, in the case of each
such Award that is a stock option, until the 90th day following such normal
performance vesting date) and shall vest and/or be forfeited based on the
satisfaction of the applicable performance goals to the same extent as if the
undersigned’s services to the Company had not ended (provided that, to the
extent any such Award is subject to both performance and service-based vesting,
the service-based vesting shall be automatically accelerated in full as of the
Date of Termination). The Award shall continue to be exercisable in accordance
with the Executive’s Award Agreement, and, with respect to Awards other than
stock options and restricted stock awards, will be settled upon vesting to the
extent such accelerated settlement is permitted by Section 409A of the Code or,
if not so permitted, on the scheduled settlement date in accordance with the

provisions that provide that in connection with a Change in Control, an Award
may be surrendered and cancelled in exchange for a cash payment.”’
