ITEM 5.  OTHER EVENTS

     On April 9, 1998, Dart Group Corporation, a Delaware corporation (the
"Company"), Richfood Holdings, Inc., a Virginia corporation ("Richfood"), and
DGC Acquisition, Inc., a Delaware corporation and wholly owned subsidiary of
Richfood ("Merger Sub"), entered into an Agreement and Plan of Merger, dated as
of April 9, 1998 (the "Merger Agreement").

     The Merger Agreement and the press release issued in connection therewith
are filed herewith as Exhibits 99.1 and 99.2, respectively, and are incorporated
herein by reference.  The description of the Merger Agreement set forth herein
does not purport to be complete and is qualified in its entirety by the
provisions of the Merger Agreement.

     The Merger Agreement provides, among other things, for the acquisition by
Richfood of all the outstanding shares of the Company's common stock, par value
$1.00 per share (the "Shares"), through (a) a tender offer (the "Offer") for all
Shares at a price of $160 per share (the "Offer Price") and (b) a second-step
merger pursuant to which Merger Sub will merge with and into the Company (the
"Merger") and all outstanding Shares (other than Shares owned by Richfood,
Merger Sub or any other subsidiary of Richfood and other than Shares held by any
dissenting stockholders) will be converted into the right to receive the Offer
Price in cash.

     The Offer is conditioned upon, among other things, there being validly
tendered before the expiration date of the Offer and not withdrawn a number of
Shares, which, together with any Shares owned by Richfood or Merger Sub,
represents at least a majority of the Shares outstanding on a fully diluted
basis and expiration of the applicable waiting period under the Hart-Scott-
Rodino Antitrust Improvements Act of 1976, as amended.  The conditions to the
Offer are set forth in Annex I to the Merger Agreement.  The Merger is subject
to various closing conditions, including, without limitation, the receipt of
stockholder approval by the Company's stockholders if required by Delaware law
and the Company's Certificate of Incorporation.

losses) the Payment Fund is inadequate to pay the amounts to which holders of
shares of Dart Common Stock shall be entitled under this Section 4.3, Richfood
                                                         -----------

Merger Subsidiary or any other wholly-owned Subsidiary of Richfood) of a
Certificate or Certificates which, immediately prior to the Effective Time,
evidenced outstanding shares of Dart Common Stock (the "Certificates"), (i) a
form of letter of transmittal (which shall specify that delivery shall be
effected, and risk of loss and title to the Certificates shall pass, only upon
proper delivery of the Certificates to the Paying Agent, and shall be in such
form and have such other provisions as Richfood reasonably may specify), and
(ii) instructions for use in effecting the surrender of the Certificates in
exchange for payment therefor. Upon surrender of a Certificate for cancellation
to the Paying Agent together with such letter of transmittal, duly executed, and
such other customary documents as may be required pursuant to such instructions,
the holder of such Certificate shall be entitled to receive in respect thereof
cash in an amount equal to the product of (x) the number of shares of Dart
Common Stock represented by such Certificate, and (y) the Merger Consideration,
and the Certificate so surrendered shall forthwith be canceled.  No interest
shall be paid or accrued on the Merger

Consideration payable upon the surrender of any Certificate.  If payment is to
be made to a Person (as defined below) other than the Person in whose name the
surrendered Certificate is registered, it shall be a condition of payment that
the Certificate so surrendered shall be properly endorsed or otherwise in proper
form for transfer and that the Person requesting such payment shall pay any
transfer or other taxes required by reason of the payment to a Person other than
the registered holder of the surrendered Certificate or establish to the
satisfaction of the Surviving Corporation that such tax has been paid or is not
applicable.  Until surrendered in accordance with the provisions of this Section

representing Shares owned by Dart or any wholly-owned Subsidiary of Dart or
Richfood, Merger Subsidiary or any other wholly-owned Subsidiary of Richfood)

Consideration.  For purposes of this Agreement, "Person" means an individual,
corporation, partnership, joint venture, association, trust, unincorporated
organization or other entity.

     (c) Termination of Payment Fund; Interest.  Any portion of the Payment Fund

Dart shall have defaulted in its obligation to make such payment within a
reasonable period of time after receipt of written request therefor from any

Merger Consideration to which they are entitled.  All interest accrued in
respect of the Payment Fund shall inure to the benefit of and be paid to
Richfood.

     (d) No Liability.  Neither Richfood nor the Surviving Corporation shall be

withhold, or cause the Paying Agent to deduct and withhold, from the
consideration otherwise payable pursuant to this Agreement to any holder of
Certificates such amounts as are required to be deducted and withheld with
respect to the making of such payment under the Code, or any provision of state,
local or foreign tax law.  To the extent that amounts are so withheld, (i) such
withheld amounts shall be treated for all purposes of this Agreement as having
been paid to the holder of the

                                     - 30 -

Certificates in respect of which such deduction and withholding was made, and

the holders of such Certificates written notice of the amounts so deducted or
withheld.

Shares under Dart's 1992 Stock Option Plan and the Option Agreements between
Dart and certain of its officers, directors, employees and consultants
thereunder (the "Stock Option Plan"), or (ii) any other option, warrant or other
right to acquire (upon purchase, exchange, conversion or otherwise) shares of
Dart Common Stock (collectively, the "Other Options" and, together with the
Employee Options, the "Options"), shall be entitled to receive for each Share
subject to such Option, in settlement and cancellation thereof, an amount
(subject to any applicable withholding tax) in cash equal to the difference
between the Merger Consideration and the per Share exercise price of such
Option, to the extent such difference is a positive number (such amount being
hereinafter referred to as, the "Option Consideration").  In addition, in the
alternative,

                                     - 31 -
<PAGE>
 
each holder of an Option outstanding at the commencement of the Offer may tender
such Option and thereby be entitled to receive for each Share subject to such
Option, upon consummation of the Offer and in settlement and cancellation of
such Option, an amount (subject to any applicable withholding tax) in cash equal
to the Option Consideration.  Notwithstanding the foregoing provisions of this
Section 4.5, with respect to any Person subject to Section 16(a) of the Exchange
- -----------                                                                     
Act, any such Option Consideration shall be paid as soon as practicable after
the first date payment can be made without liability to such Person under
Section 16(b) of the Exchange Act.  Dart represents and warrants to Richfood and
Merger Subsidiary that the Stock Option Plan has been or will be amended to the
extent necessary to give effect to the foregoing as of the commencement of the
Offer.  Upon receipt of the related Option Consideration, the Option shall be
canceled.  The surrender of an Option to Dart in exchange for the Option
Consideration shall be deemed a release of any and all rights the holder had or
may have had in respect of such Option.

such shares in accordance with Section 262 of the DGCL (collectively, the
"Dissenting Shares") shall not be converted into or represent the right to

Effective Time, represent only the right to receive payment of the appraised
value of such shares of Dart Common Stock held by them in accordance with the
provisions of such Section 262, except that all Dissenting Shares held by
stockholders who shall have failed to perfect or who effectively shall have
withdrawn or lost their rights to appraisal of such shares of Dart Common Stock

Proposal that the Board of Directors of Dart believes, in its good faith
judgment, is reasonably likely to result in a Superior Proposal; provided, that

     order, decree, injunction or other order which is in effect and which (1)
     materially restricts, prevents or prohibits consummation of the Offer or

     connection with the transactions contemplated by this Agreement in amounts
     that would have a Material Adverse Effect on Dart, (2) prohibits or limits

     such determination (except as to any such representation or warranty which
     speaks as of a specific date, which must be untrue or incorrect as of such
     specific date) except where the failure to be so true and correct would
     not, individually or in the aggregate, reasonably be expected to (i) have a
     Material Adverse Effect on Dart, (ii) prevent the consummation of the Offer
     or (iii) have a material adverse effect on the benefits to Richfood of the
     transactions contemplated by this Agreement;

          (c) (i)  Dart shall not have performed, in all material respects, all

     by, any Governmental Authority requisite to consummation of the Merger and

     have otherwise learned that any Person or "group" (as defined in Section
     13(d)(3) of the Exchange Act), other than Richfood or its affiliates or any

     The foregoing conditions are for the sole benefit of Merger Subsidiary and
its affiliates and, subject to the terms of the Agreement, may be asserted by

at any time and from time to time.  Unless otherwise defined herein, capitalized
terms used herein shall have the meanings ascribed to them in the Agreement
among Richfood, Merger Subsidiary and Dart to which this Annex I is attached.

Dart Group to Be Acquired by Richfood Holdings

LANDOVER, Md., April 9 /PRNewswire/ -- Richard B. Stone, Chairman of Dart Group
Corporation (Nasdaq: DART - news), announced today that Dart has entered into a
definitive merger agreement with Richfood Holdings, Inc. (NYSE: RFH - news) that
provides for the acquisition of Dart by Richfood at a price of $160 per share in
cash. The company's Board of Directors unanimously approved the Richfood tender
offer and the execution of the merger agreement.

Under the terms of the merger agreement, Richfood will commence a cash tender
offer for all outstanding shares of Dart's common stock at $160 per share within
five business days. The completion of the tender offer is not subject to
financing, but is subject to a number of other customary conditions, including a
majority of Dart's outstanding shares on a fully diluted basis being tendered
and the expiration of the waiting period under the Hart-Scott-Rodino Act.
Following the successful completion of the Richfood tender offer, all shares not
purchased in the tender offer will be converted in a subsequent merger into the
right to receive $160 per share in cash and Dart will become a wholly owned
subsidiary of Richfood. The merger is also subject to various conditions.

Mr. Stone said, "We are very pleased to have achieved this transaction which we
believe to be in the best interests of our shareholders."

Wasserstein Perella & Co., Inc. acted as financial advisor to Dart.
