Section 4.3 - Manner of Exercise

The Option, or any exercisable portion thereof, may be exercised solely by delivery to the Secretary of the Company of all of the following prior to the time when the Option or such portion becomes unexercisable under Section 3.3:

(b)(i)Full payment (in cash or by check) for the shares with respect to which the Option or portion is exercised; or

(ii)If the Committee in its sole discretion shall so permit, shares of Common Stock owned by the Employee duly endorsed for transfer to the Company with a fair market value on the date of delivery equal to the aggregate purchase price of the shares with respect to which the Option or portion is exercised;

(iii) If the Committee in its sole discretion shall so permit, through a cashless exercise; or

(iv)If the Committee in its sole discretion shall so permit, a combination of the consideration provided in the foregoing subsections 4.3(b)(i), 4.3(b)(ii) and 4.3(b)(iii);

The written representation and agreement referred to in the first sentence of this subsection 4.3(c) shall, however, not be required if the shares to be issued pursuant to such exercise have been registered under the Act, and such registration is then effective in respect of such shares; and
