Adjustment of the Number of Shares and Exercise Price
Under certain circumstances, the number of shares subject to any option grantor bonus award and the number of reserved for issuance under the L-T Plan (but not yet covered by an option or bonus) will be adjusted. These circumstances include the following: stock dividend; stock split, or any other capital change that the Committee deems to require an equitable adjustment. If the number of shares subject to option is adjusted for any reason, the option price for each share will be adjusted such that the price per share multiplied by the number of shares remains the same both before and after the adjustment.
