Thirty-three and one third percent (33 1/3%) of the restricted stock units shall vest on each of the first, second and third anniversaries of June 21, 2005.  These shares cannot be sold while serving as a member of the Board of Directors for Circuit City Stores, Inc.
Thirty-three and one third percent (33 1/3%) of the Units paid as a dividend in connection with the restricted stock units granted on 6/21/2005 have vested and are now included in the phantom stock account until the reporting person ceases to serve as a director of the company.
This director has elected to defer payment under the Restricted Stock Unit Deferral Program (the "Program") of the restricted stock units issued under the Circuit City Stores, Inc. 2000 Non-Employee Director Stock Incentive Plan.  Vested deferred shares are held as "phantom stock" in a phantom stock account.  Dividends on vested and unvested shares will be reinvested until distributions are made.  The shares underlying the phantom stock units in the director's account will be distributed to the director when he or she ceases to serve as a director of the company.
