The term during which each option may be exercised shall be determined by the Committee, but if required by the Code and except as otherwise provided herein, no option shall be exercisable in whole or in part more than seven years from the date it is granted, and no Incentive Stock Option granted to an employee who at the time of the Grant owns more than 10% of the total combined voting power of all classes of stock of the Company or any of its Subsidiaries shall be exercisable more than five years from the date it is granted. All rights to purchase Shares pursuant to an option shall, unless sooner terminated, expire at the date designated by the Committee. The Committee shall determine the date on which each option shall become exercisable and may provide that an option shall become exercisable in installments. The Shares constituting each installment may be purchased in whole or in part at any time after such installment becomes exercisable, subject to such minimum exercise requirements as may be designated by the Committee. Prior to the exercise of an option and delivery of the Shares represented thereby, the optionee shall have no rights as a stockholder with respect to any Shares covered by such outstanding option (including any dividend or voting rights).
