Each Stock Option agreement shall state the period or periods of time within which the Stock Option may be exercised, in whole or in part, which shall be such period or periods of time as may be determined by the Committee, provided that no Incentive Stock Option shall be exercisable after ten years from the date of grant thereof (or, in the case of an Incentive Stock Option granted to an employee referred to in Section 6.7(ii) below, such term shall in no event exceed five years from the date on which such Incentive Stock Option is granted). Each Stock Option agreement shall also state any conditions which must be satisfied before all or a portion of the Stock Option may be exercised. In so doing, the Committee may specify that a Stock Option may not be exercised until the completion of a service period or until Performance Goals are satisfied.
