Section 3.1Commencement of Exercisability
(a) an Option to Purchase shall become exercisable as follows:
Notwithstanding the foregoing, (x) no Option to Purchase shall become exercisable prior to the time the Plan is approved by the Company's stockholders, and (y) subject to the immediately preceding clause (x), the Option to Purchase shall become immediately exercisable as to 100% of the shares of Common Stock subject to such Option to Purchase immediately prior to a Change of Control (but only to the extent such Option to Purchase has not otherwise terminated or become exercisable). The sale or disposition of a division, business segment or Subsidiary of the Company shall not cause an Option to Purchase to become immediately exercisable. Pursuant to the authority granted to it in Section 5.1, the Committee shall decide what, if any, Option to Purchase shall become exercisable and when any such Option to Purchase must be exercised upon the sale or disposition of a division, business segment or Subsidiary of the Company.
(b) Notwithstanding the foregoing, no Option to Purchase shall become exercisable as to any additional shares of Common Stock following the termination of employment of the Optionee for any reason other than a termination of employment because of the death or Permanent Disability or Retirement of the Optionee, and any Option to Purchase (other than as provided in the next succeeding sentence) which is non-exercisable as of the Optionee's termination of employment shall be immediately cancelled. In the event of a termination of employment because of death or Permanent Disability of the Optionee and provided that the Optionee has been employed for at least three years, the Option to Purchase awarded hereunder shall become immediately exercisable. If the Optionee has not been employed for at least three years, then the Option to Purchase shall not become exercisable for any additional shares of Common Stock. In the event of a termination of employment because of Retirement of the Optionee, the Option to Purchase the Committee in its sole and absolute discretion shall have the authority to decide if any Option to Purchase that is not exercisable as of the date of Retirement shall continue to vest and be exercisable as though the Optionee's employment had not been terminated.
