A Stock Unit 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). If vesting of a Stock Unit Award is conditioned on the achievement of specified performance goals, the extent to which they are achieved over the specified performance period shall determine the number of Stock Units that will be earned and eligible to vest, which may be greater or less than the target number of Stock Units stated in the Agreement. 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 settlement of a Stock Unit Award.
