Shares subject to a Restricted Stock Award shall be subject to vesting and the lapse of applicable restrictions based on such conditions or factors and occurring over such period of time as the Committee may determine in its discretion, subject to the limitations provided in Section 6(b). The Committee may provide whether any consideration other than Services must be received by the Company or any Affiliate as a condition precedent to the grant of a Restricted Stock Award, and may correspondingly provide for Company reacquisition or repurchase rights if such additional consideration has been required and some or all of a Restricted Stock Award does not vest.
