(c) The Option shall become immediately exercisable in full after a Change in Control (as defined in Appendix A to this Agreement). However, if you are or become a participant in the Company’s applicable Income Security Plan or any successor or substitute plan (the “ISP”), the terms relating to the exercisability of the Option, including whether a Change in Control has occurred, shall be governed by the provisions of the ISP.

(a)    For three years if your termination of employment is a result of your death, to the extent exercisable on the date of death;

(b)    For three years if your termination of employment is a result of your Retirement or Disability (as each of those terms is defined in Appendix A to this Agreement) or involuntary termination without cause, to the extent exercisable on the date of such termination of employment, provided, however, that if you die less than six months before the end of such three-year period, your appropriate representatives may exercise the Option at any time within six months after your death, even if such exercise occurs more than three years after your termination of employment; or

(c)    For 90 days after your termination of employment for any other reason, other than for cause, to the extent exercisable on the date of such termination of employment.

The Option may not be exercised following your termination of employment for cause.
