Except as provided in the Management Stockholder’s Agreement, during the lifetime of the Optionee, only he may exercise an Option or any portion thereof.  After the death of the Optionee, any exercisable portion of an Option may, prior to the time when an Option becomes unexercisable under Section 3.2, be exercised by his personal representative or by any person empowered to do so under the Optionee’s will or under the then applicable laws of descent and distribution.

Section 4.2 - - Partial Exercise

Any exercisable portion of an Option or the entire Option, if then wholly exercisable, may be exercised in whole or in part at any time prior to the time when the Option or portion thereof becomes unexercisable under Section 3.2; provided, however, that any partial exercise shall be for whole shares of Common Stock only.

An Option, or any exercisable portion thereof, may be exercised solely by delivering to the Secretary or his office all of the following prior to the time when the Option or such portion becomes unexercisable under Section 3.2:

(a)  Notice in writing signed by the Optionee or the other person then entitled to exercise the Option or portion thereof, stating that the Option or portion thereof is thereby exercised, such notice complying with all applicable rules established by the Committee;

(a)  The obtaining of approval or other clearance from any state or federal governmental agency which the Committee shall, in its absolute discretion, determine to be necessary or advisable; and

(b)  The lapse of such reasonable period of time following the exercise of the Option as the Committee may from time to time establish for reasons of administrative convenience.
