                             DART GROUP CORPORATION

                 DART GROUP CORPORATION 1992 STOCK OPTION PLAN

                                 1998 AMENDMENT

          Pursuant to Section 17 of the Dart Group Corporation 1992 Stock Option
Plan (the "Plan"), the Board of Directors hereby amends the Plan as follows:

          1.   SECTION TEN is amended by adding at the end thereof the
following:

          However, nothing in this Section Ten shall prevent a Participant from
          tendering his Options in exchange for cash pursuant to a tender offer
          by DGC Acquisition, Inc., a Delaware corporation ("DGC"), pursuant to
          an agreement and plan of merger entered into by and among the Company,
          Richfood Holdings, Inc., a Virginia corporation, and DGC Acquisition,
          Inc. (the "Merger Agreement").

          2.   SECTION THIRTEEN is amended by adding at the end thereof the
following:

          In the event of a tender offer by DGC pursuant to the Merger
          Agreement, Participants may tender their Options in connection with
          the tender offer in exchange for cash from DGC, for each share of
          stock that is subject to such holder's Options, equal to the
          difference between the price per share offered by DGC in the tender
          offer, and the per share exercise price of such holder's Options,
          which amount may be reduced by any required withholding tax.  Option
          holders who do not participate in the tender offer will receive cash
          from DGC, for each share that is subject to such Options that have not
          been exercised or tendered as of the effective date of the merger,
          equal to the difference between the Merger Consideration (as defined
          in the Merger Agreement) per share payable to the Company shareholders
          who do not tender their stock in the tender offer and the per share
          exercise price of such Options, which amount may be reduced by any
          required withholding tax.
