determine the number of Grant Shares to be awarded to a Participant.

          Restricted Shares shall be transferred to Participants without other

conditions as the Committee determines appropriate, including, without
limitation, restrictions on sale or other disposition.

      6.       Vesting.

          pro rata in accordance with their stockholdings in the Company
          received pursuant to the terms of the Management Agreement by and
          between the Company and TeleCorp Management Corp., as of the date of
          such Management Agreement.

               (d) If the Participant's employment with the Company or one of
          its subsidiaries terminates prior to full vesting in any Grant Shares
          awarded hereunder by reason of his retirement under a retirement plan
          maintained by the Company or one of its subsidiaries, the Committee
          may, in its discretion, specify that any Grant Shares awarded to the
          Participant become vested at that time, at a future date or upon the
          completion of such other conditions as the Committee, in its sole
          discretion, may provide.
