TO THE HOLDERS OF COMMON STOCK OFDART GROUP CORPORATION:
 
                                 INTRODUCTION
 
  DGC Acquisition, Inc., a Delaware corporation ("Purchaser"), hereby offers
to purchase all the outstanding shares of common stock, $1.00 par value per
share (the "Shares"), of Dart Group Corporation, a Delaware corporation (the
"Company"), at a purchase price of $160.00 per Share (the "Offer Price"), net
to the seller in cash, upon the terms and subject to the conditions set forth
in this Offer to Purchase and in the related Letter of Transmittal (which,
together with any amendments or supplements hereto or thereto, collectively
constitute the "Offer"). Purchaser is a direct, wholly-owned subsidiary of
Richfood Holdings, Inc., a Virginia corporation ("Parent").
 
  The Offer is being made pursuant to an Agreement and Plan of Merger, dated
as of April 9, 1998 (the "Merger Agreement"), by and among Parent, Purchaser
and the Company. The Merger Agreement provides, among other things, for the
commencement of the Offer by Purchaser and further provides that, after the
purchase of Shares pursuant to the Offer and subject to the satisfaction or
waiver of certain conditions set forth therein, Purchaser will be merged with
and into the Company (the "Merger"), with the Company surviving the Merger as
a direct wholly-owned subsidiary of Parent (the "Surviving Corporation"),
which shall continue under the name Dart Group Corporation. In the Merger,
each Share issued and outstanding (excluding Shares owned, directly or
indirectly, by the Company or any wholly-owned subsidiary of the Company or by
Parent, Purchaser or any other wholly-owned subsidiary of Parent and excluding
Shares owned by stockholders of the Company who shall have properly perfected
their appraisal rights under Delaware law) immediately prior to the effective
time of the Merger (the "Effective Time") will be converted at the Effective
Time into the right to receive the Offer Price in cash, without any interest
thereon (the "Merger Consideration"). If Purchaser acquires a majority of the
outstanding Shares, it will have sufficient voting power to approve and adopt
the Merger Agreement and the Merger without the vote of any other stockholder
of the Company. If Purchaser acquires at least 90% of the outstanding Shares,
Parent intends to cause Purchaser to approve and consummate the Merger without
any action by, or any further prior notice to, the other stockholders of the
Company pursuant to the short-form merger provisions of the Delaware General
Corporation Law (the "DGCL").
 
  THE BOARD OF DIRECTORS OF THE COMPANY (THE "BOARD") HAS UNANIMOUSLY
DETERMINED THAT THE OFFER AND THE MERGER ARE FAIR TO, AND IN THE BEST
INTERESTS OF, THE COMPANY AND THE COMPANY'S STOCKHOLDERS (THE "STOCKHOLDERS");
HAS APPROVED THE MERGER AGREEMENT AND THE TRANSACTIONS CONTEMPLATED THEREBY,
INCLUDING THE OFFER AND THE MERGER; AND RECOMMENDS THAT THE STOCKHOLDERS
ACCEPT THE OFFER AND TENDER ALL OF THEIR SHARES PURSUANT THERETO.
 
  WASSERSTEIN PERELLA & CO., INC., THE COMPANY'S FINANCIAL ADVISOR
("WASSERSTEIN"), HAS DELIVERED TO THE COMPANY ITS WRITTEN OPINION DATED APRIL
8, 1998, THAT, AS OF SUCH DATE AND SUBJECT TO THE MATTERS STATED THEREIN, THE
CONSIDERATION TO BE RECEIVED BY HOLDERS OF THE SHARES IN THE OFFER AND THE
MERGER AS CONTEMPLATED BY THE MERGER AGREEMENT IS FAIR, FROM A FINANCIAL POINT
OF VIEW, TO SUCH STOCKHOLDERS. WASSERSTEIN'S OPINION IS DIRECTED ONLY TO THE
FAIRNESS, FROM A FINANCIAL POINT OF VIEW, OF THE CASH CONSIDERATION TO BE
RECEIVED IN THE OFFER AND THE MERGER TO HOLDERS OF SHARES AND IS NOT INTENDED
TO CONSTITUTE, AND DOES NOT CONSTITUTE, A RECOMMENDATION AS TO WHETHER ANY
STOCKHOLDER SHOULD TENDER SHARES PURSUANT TO THE OFFER. A COPY OF THE WRITTEN
OPINION OF WASSERSTEIN IS CONTAINED IN THE COMPANY'S SOLICITATION/
RECOMMENDATION STATEMENT ON SCHEDULE 14D-9 ("SCHEDULE 14D-9") FILED WITH THE
SECURITIES AND EXCHANGE COMMISSION (THE "COMMISSION") IN CONNECTION WITH THE
OFFER, A COPY OF WHICH IS BEING FURNISHED TO STOCKHOLDERS CONCURRENTLY WITH
THIS OFFER TO PURCHASE.
<PAGE>
 
  The Offer is conditioned upon, among other things, (i) a number of Shares
representing a majority of all outstanding Shares on a fully diluted basis
being validly tendered and not withdrawn prior to the Expiration Date (as
defined in Section 1 hereof) (the "Minimum Tender Condition"); and (2) the
expiration of the applicable waiting period under the Hart-Scott-Rodino
Antitrust Improvements Act of 1976, as amended (the "HSR Act"), and receipt of
any required regulatory consents and approvals. See Sections 1 and 14, which
set forth the conditions of the Offer, and Section 15, which discusses certain
legal matters and regulatory consents and approvals.
 
  The Company has represented and warranted to Purchaser that, as of April 6,
1998, 1,202,502 Shares were issued and outstanding and that no Company
preferred stock was issued and outstanding. The number of outstanding shares
does not include 91,436 Shares to be issued pursuant to certain outstanding
options to acquire Shares.
 
  The consummation of the Merger is subject to the satisfaction or waiver of a
number of conditions, including, if required, the approval of the Merger by
the requisite vote or consent of the Stockholders. Under the DGCL, the
stockholder vote necessary to approve the Merger will be the affirmative vote
of at least a majority of the outstanding Shares, including Shares held by
Purchaser and its affiliates. If the Minimum Tender Condition is satisfied and
Purchaser purchases at least a majority of the outstanding Shares in the
Offer, Purchaser will be able to effect the Merger without the affirmative
vote of any other Stockholders. If Purchaser acquires at least 90% of the
outstanding Shares pursuant to the Offer or otherwise, Purchaser will be able
to effect the Merger pursuant to the "short-form" merger provisions of
Section 253 of the DGCL, without prior notice to, or any action by, any other
Stockholder. In that event, Purchaser intends to effect the Merger as promptly
as practicable following the purchase of Shares in the Offer. See Section 12.
 
  The Merger Agreement is more fully described in Section 12. Certain federal
income tax consequences of the sale of Shares pursuant to the Offer and the
exchange of Shares for the Merger Consideration pursuant to the Merger are
described in Section 5.
 
  Purchaser is not tendering for, and the Offer does not encompass, the
preferred share purchase rights (the "Rights") issued by the Company pursuant
to the Rights Agreement, dated as of February 17, 1998 (the "Rights
Agreement"), between the Company and The Bank of New York, as rights agent.
The Company has represented and warranted to Parent and Purchaser that the
Company's Board of Directors has (i) determined that the Distribution Date (as
defined in the Rights Agreement) that would otherwise occur by virtue of the
commencement of the Offer shall be indefinitely postponed, and (ii) approved
the redemption of the Rights pursuant to the Rights Agreement in connection
with the Offer and the Merger. The Company shall cause such redemption to
occur immediately prior to Purchaser's purchase of Shares pursuant to the
Offer.
 
  Tendering Stockholders will not be obligated to pay brokerage fees or
commissions or, except as set forth in Instruction 6 to the Letter of
Transmittal, transfer taxes on the purchase of Shares pursuant to the Offer or
the Merger. Purchaser will pay all charges and expenses of Donaldson, Lufkin &
Jenrette Securities Corporation ("DLJ"), in its capacity as the dealer manager
(the "Dealer Manager"), First Union National Bank, as the depositary (the
"Depositary"), and Corporate Investor Communications, Inc., as the information
agent (the "Information Agent"), in connection with the Offer. See Section 16.
 
  THE OFFER TO PURCHASE AND THE RELATED LETTER OF TRANSMITTAL CONTAIN
IMPORTANT INFORMATION THAT SHOULD BE READ CAREFULLY BEFORE ANY DECISION IS
MADE WITH RESPECT TO THE OFFER.

                                   THE OFFER
 
  1. TERMS OF THE OFFER
 
  Upon the terms and subject to the conditions of the Offer (including, if the
Offer is extended or amended, the terms and conditions of any such extension
or amendment), Purchaser will accept for payment (and thereby purchase) all
Shares that are validly tendered and not withdrawn in accordance with Section
4 below prior to the Expiration Date. As used in the Offer, the term
"Expiration Date" means 12:00 midnight, New York City time, on Tuesday, May
12, 1998, unless and until Purchaser, in accordance with the terms of the
Offer and the Merger Agreement, shall have extended the period of time during
which the Offer is open, in which event the term "Expiration Date" means the
latest time and date at which the Offer, as so extended, expires. As used in
this Offer to Purchase, "business day" has the meaning set forth in Rule 14d-
1(c)(6) under the Securities Exchange Act of 1934, as amended (the "Exchange
Act").
 
  In the event that the Offer is not consummated, Purchaser may seek to
acquire additional Shares through open market purchases, privately negotiated
transactions or otherwise, upon such terms and conditions and at such prices
as it shall determine, which may be more or less than the Offer Price and
could be for cash or other consideration.
 
  The Offer is conditioned upon, among other things, satisfaction of the
Minimum Tender Condition and the expiration or termination of all waiting
periods imposed by the HSR Act. The Offer is also subject to certain other
conditions that are set forth in Section 14 below. Pursuant to the terms of
the Merger Agreement, Purchaser expressly reserves the right (but will not be
obligated) to waive any or all of the conditions of the Offer in its sole
discretion (other than the Minimum Tender Condition, which Purchaser may not
waive).
 
  The Merger Agreement provides that Purchaser may not extend the Expiration
Date (except as required by law or the applicable rules and regulations of the
Commission), provided, however, that (i) the Offer may be extended in
connection with an increase in the consideration to be paid pursuant to the
Offer so as to comply with applicable rules and regulations of the Commission,
(ii) Purchaser may extend the Offer for up to ten (10) business days after the
initial Expiration Date if fewer than 90% of the Shares outstanding as of such
date have been tendered at such date, so long as, in connection with such
extension, Purchaser irrevocably waives the conditions to the Offer described
in clauses (b), (c), (f), (g)(1) and (h) of Section 14 (Conditions to the
Offer) hereof, and (iii) Purchaser shall extend the Offer from time to time
until June 30, 1998, if, and to the extent that, at the initial expiration of
the Offer, or any subsequent extension thereof, all conditions to the Offer
have not been satisfied or waived and the failure of a condition to be
satisfied is not due to the failure of the Company to fulfill any of its
obligations under the Merger Agreement. Purchaser will give oral or written
notice of any such extension to the Depositary and by making a public
announcement of such extension. There can be no assurance that Purchaser will
exercise any optional right to extend the Offer.
 
  Purchaser expressly reserves the right, subject to applicable law (including
applicable rules and regulations of the Commission promulgated under the
Exchange Act) and the terms of the Merger Agreement, at any time or from time
to time, to (i) delay acceptance for payment of, or payment for, any Shares,
regardless of whether the Shares were theretofore accepted for payment, or to
terminate the Offer and not accept for payment or pay for any Shares not
theretofore accepted for payment or paid for, upon the occurrence of any of
the conditions specified in Section 14 below, by giving oral or written notice
of such delay in payment or termination to the Depositary, and (ii) waive any
conditions or otherwise amend the Offer in any respect, by giving oral or
written notice to the Depositary. Any extension, delay in payment, termination
or amendment will be followed as promptly as practicable by public
announcement, the announcement in the case of an extension to be issued no
later than 9:00 a.m., New York City time, on the next business day after the
previously scheduled Expiration Date. Without limiting the manner in which
Purchaser may choose to make any public announcement, Purchaser will have no
obligation to publish, advertise or otherwise communicate any such
announcement, other than by issuing a release to the Dow Jones News Service or
as otherwise required by law. The reservation by Purchaser
 
                                       3
<PAGE>
 
of the right to delay acceptance for payment of or payment for Shares is
subject to the provisions ofRule 14e-1(c) under the Exchange Act, which
requires that Purchaser pay the consideration offered or return the Shares
deposited by or on behalf of Stockholders promptly after the termination or
withdrawal of the Offer.
 
  Subject to the terms of the Merger Agreement, Purchaser expressly reserves
the right to increase the price per Share payable in the Offer or to make any
other changes in the terms and conditions of the Offer, except that, without
the prior written consent of the Company, Purchaser shall not (i) decrease or
change the form of the Offer Price or decrease the number of Shares sought
pursuant to the Offer, (ii) impose additional conditions to the Offer, (iii)
extend the expiration date for the Offer (except as described above) or (iv)
amend any term of the Offer in any manner adverse to Stockholders. Assuming
the prior satisfaction or waiver of the conditions to the Offer, Purchaser
shall accept for payment, and pay for, in accordance with the terms of the
Offer, all Shares validly tendered and not withdrawn pursuant to the Offer as
soon as practicable after the Expiration Date.
 
  If Purchaser makes a material change in the terms of the Offer or the
information concerning the Offer or waives a material condition of the Offer,
Purchaser will disseminate additional tender offer materials and extend the
Offer to the extent required by Rules 14d-4(c), 14d-6(d) and 14e-1 under the
Exchange Act. The minimum period during which an offer must remain open
following material changes in the terms of the Offer or information concerning
the Offer, other than a change in price or a change in percentage of
securities sought, will depend upon the facts and circumstances then existing,
including the relative materiality of the changed terms or information. If
Purchaser decides to increase or, subject to the consent of the Company, to
decrease the consideration in the Offer, or to change or waive the Minimum
Tender Condition and if, at the time that notice of any such change or waiver
is first published, sent or given to Stockholders, the Offer is scheduled to
expire at anytime earlier than the tenth business day after (and including)
the date of that notice, the Offer will be extended at least until the
expiration of that period of ten business days.
 
  The Company has provided Purchaser with its stockholder list and security
position listings for the purpose of disseminating the Offer to Stockholders.
This Offer to Purchase, the related Letter of Transmittal and other relevant
materials will be mailed to record holders of Shares and will be furnished to
brokers, dealers, commercial banks, trust companies and similar persons whose
names, or the names of whose nominees, appear on the Company's stockholder
list or, if applicable, who are listed as participants in a clearing agency's
security position listing for subsequent transmittal to beneficial owners of
Shares.
 
  2. ACCEPTANCE FOR PAYMENT AND PAYMENT FOR SHARES
 
  Upon the terms and subject to the conditions of the Merger Agreement and the
Offer (including, if the Offer is extended or amended, the terms and
conditions of any such extension or amendment), Purchaser will accept for
payment, and will pay for, all Shares that are validly tendered on or prior to
the Expiration Date, and not properly withdrawn in accordance with Section 4
below, as soon as practicable after the Expiration Date. All questions as to
the satisfaction of such terms and conditions will be determined by Purchaser
in its sole discretion, which determination will be final and binding. Subject
to the applicable rules of the Commission, Purchaser expressly reserves the
right to delay acceptance for payment of or payment for Shares in order to
comply, in whole or in part, with any applicable law or government regulation.
Any such delays will be effected in compliance with Rule 14e-1(c) under the
Exchange Act (relating to a bidder's obligation to pay for or return tendered
securities promptly after the termination or withdrawal of such bidder's
offer). See Section 15 below.
 
  In all cases, payment for Shares purchased pursuant to the Offer will be
made only after timely receipt by the Depositary of (i) certificates
evidencing (or a timely Book-Entry Confirmation (as defined in Section 3
below) with respect to) such Shares, (ii) a Letter of Transmittal (or a
manually signed facsimile thereof), properly completed and duly executed with
any required signature guarantees, or, in the case of a book-entry transfer,
an Agent's Message (as defined below) and (iii) any other documents required
by the Letter of Transmittal. See Section 3 below.
 
  The term "Agent's Message" means a message, transmitted by a Book-Entry
Transfer Facility (as defined in Section 3 below) to, and received by, the
Depositary and forming part of a Book-Entry Confirmation, which
 
                                       4
<PAGE>
 
states that (i) such Book-Entry Transfer Facility has received an express
acknowledgment from the participant in such Book-Entry Transfer Facility
tendering Shares that are the subject of such Book-Entry Confirmation,
(ii) such participant has received and agrees to be bound by the terms of the
Letter of Transmittal and (iii) Purchaser may enforce such agreement against
such participant.
 
  For purposes of the Offer, Purchaser will be deemed to have accepted for
payment (and thereby purchased) Shares properly tendered to Purchaser and not
withdrawn, if and when Purchaser gives oral or written notice to the
Depositary of Purchaser's acceptance of such Shares. In all cases, payment for
Shares accepted for payment pursuant to the Offer will be made by deposit of
the purchase price therefor with the Depositary, which will act as agent for
tendering Stockholders for the purpose of receiving payment from Purchaser and
transmitting payment to tendering Stockholders.
 
  If, for any reason, acceptance for payment of any Shares tendered pursuant
to the Offer is delayed, or Purchaser is unable to accept for payment Shares
tendered pursuant to the Offer, then, without prejudice to Purchaser's rights
under the Offer (but subject to Rule 14e-1(c) under the Exchange Act), the
Depositary may, nevertheless, on behalf of Purchaser, retain tendered Shares,
and such Shares may not be withdrawn, except to the extent that the tendering
Stockholders are entitled to exercise, and do exercise, withdrawal rights as
described in Section 4 below. UNDER NO CIRCUMSTANCES WILL INTEREST BE PAID ON
THE OFFER PRICE BY PURCHASER, REGARDLESS OF ANY EXTENSION OF THE OFFER OR ANY
DELAY IN MAKING SUCH PAYMENT.
 
  If any tendered Shares are not purchased pursuant to the Offer for any
reason or if certificates are submitted for more Shares than are tendered,
certificates for Shares not purchased or tendered will be returned pursuant to
the instructions of the tendering Stockholder without expense to the tendering
Stockholder (or, in the case of Shares delivered by book-entry transfer into
the Depositary's account at a Book-Entry Transfer Facility pursuant to the
procedures set forth in Section 3 below, the Shares will be credited to an
account maintained at the appropriate Book-Entry Transfer Facility) as
promptly as practicable following the expiration or termination of the Offer.
 
  If, prior to the Expiration Date, Purchaser increases the consideration to
be paid per Share pursuant to the Offer, Purchaser will pay the increased
consideration for all Shares purchased pursuant to the Offer, whether or not
the Shares were tendered prior to the increase in consideration.
 
  Purchaser reserves the right to transfer or assign, in whole or from time to
time in part, to Parent or to one or more of its affiliates, the right to
purchase Shares tendered pursuant to the Offer, but any such transfer or
assignment will not relieve Purchaser of its obligations under the Offer and
will in no way prejudice the rights of tendering Stockholders to receive
payment for Shares validly tendered and accepted for payment pursuant to the
Offer.
 
  3. PROCEDURE FOR TENDERING SHARES
 
  Valid Tenders. For a Stockholder to tender validly pursuant to the Offer,
either: (i) a Letter of Transmittal (or a manually signed facsimile thereof),
properly completed and duly executed, together with any required signature
guarantees, or, in the case of a book-entry transfer, an Agent's Message, and
any other required documents, must be received by the Depositary at one of its
addresses set forth on the back cover of this Offer to Purchase prior to the
Expiration Date and either (a) certificates evidencing Shares must be received
by the Depositary at any such address prior to the Expiration Date, or (b) the
Shares must be delivered pursuant to the procedures for book-entry transfer
set forth below and a Book-Entry Confirmation (as defined below) must be
received by the Depositary prior to the Expiration Date; or (ii) the tendering
Stockholder must comply with the guaranteed delivery procedures set forth
below. No alternative, conditional or contingent tenders will be accepted.
 
                                       5
<PAGE>
 
  Book-Entry Transfer. The Depositary will establish accounts with respect to
the Shares at the Depository Trust Company, Midwest Securities Trust Company
and Philadelphia Depository Company (each, a "Book-Entry Transfer Facility"
and, collectively, the "Book-Entry Transfer Facilities") for purposes of the
Offer within two business days after the date of this Offer to Purchase. Any
financial institution that is a participant in any of the Book-Entry Transfer
Facilities' systems may make book-entry delivery of Shares by causing a Book-
Entry Transfer Facility to transfer the Shares into the Depositary's account
at the Book-Entry Transfer Facility in accordance with that Book-Entry
Transfer Facility's procedures for such transfer. However, although delivery
of the Shares may be effected through book-entry transfer into the
Depositary's account at a Book-Entry Transfer Facility, the Letter of
Transmittal (or a manually signed facsimile thereof), properly completed and
duly executed, with any required signature guarantees, or an Agent's Message,
and any other required documents, must, in any case, be transmitted to, and
received by, the Depositary at one of its addresses set forth on the back
cover of this Offer to Purchase prior to the Expiration Date, or the tendering
Stockholder must comply with the guaranteed delivery procedures described
below. The confirmation of a book-entry transfer of Shares into the
Depositary's account at a Book-Entry Transfer Facility as described above is
referred to as a "Book-Entry Confirmation." DELIVERY OF DOCUMENTS TO A BOOK-
ENTRY TRANSFER FACILITY IN ACCORDANCE WITH THE BOOK-ENTRY TRANSFER FACILITY'S
PROCEDURES DOES NOT CONSTITUTE DELIVERY TO THE DEPOSITARY.
 
  THE METHOD OF DELIVERY OF CERTIFICATES FOR SHARES, THE LETTER OF TRANSMITTAL
AND ANY OTHER REQUIRED DOCUMENTS IS AT THE OPTION AND RISK OF THE TENDERING
STOCKHOLDER. IF DELIVERY IS MADE BY MAIL, REGISTERED MAIL WITH RETURN RECEIPT
REQUESTED, PROPERLY INSURED, IS RECOMMENDED. IN ALL CASES, SUFFICIENT TIME
SHOULD BE ALLOWED TO ENSURE TIMELY DELIVERY.
 
  Signature Guarantees. No signature guarantee is required on the Letter of
Transmittal: (i) if the Letter of Transmittal is signed by the registered
holder(s) (which term, for purposes of this Section, includes any participant
in any of the Book-Entry Transfer Facilities' systems whose name appears on a
security position listing as the owner of the Shares) of Shares tendered
therewith and such registered holder has not completed either the box entitled
"Special Delivery Instructions" or the box entitled "Special Payment
Instructions" on the Letter of Transmittal; or (ii) if such Shares are
tendered for the account of a financial institution (including most commercial
banks, savings and loan associations and brokerage houses) that is a
participant in the Security Transfer Agents Medallion Program, the New York
Stock Exchange Medallion Signature Guarantee Program or the Stock Exchange
Medallion Program (an "Eligible Institution"). In all other cases, all
signatures on the Letter of Transmittal must be guaranteed by an Eligible
Institution. See Instruction 1 of the Letter of Transmittal. If the
certificates evidencing Shares are registered in the name of a person other
than the signer of the Letter of Transmittal or if payment is to be made or
certificates for Shares not tendered or not accepted for payment are to be
returned to a person other than the registered holder of the certificates
surrendered, then the tendered certificates evidencing Shares must be endorsed
or accompanied by appropriate stock powers, in each case signed exactly as the
name (or names) of the registered holder or owners appears on the
certificates, with the signatures on the certificates or stock powers
guaranteed as described above and as provided in the Letter of Transmittal.
See Instructions 1 and 5 of the Letter of Transmittal.
 
  Guaranteed Delivery. If a Stockholder wishes to tender Shares pursuant to
the Offer and the Stockholder's certificates are not immediately available or
the procedures for book-entry transfer cannot be completed on a timely basis
or time will not permit all required documents to reach the Depositary prior
to the Expiration Date, such Stockholder's tender may be effected if all of
the following conditions are met:
 
    (i) the tender is made by or through an Eligible Institution;
 
    (ii) a properly completed and duly executed Notice of Guaranteed
  Delivery, substantially in the form provided by Purchaser, is received by
  the Depositary (as provided below) prior to the Expiration Date; and
 
    (iii) the certificates for all tendered Shares in proper form for
  transfer (or a Book-Entry Confirmation with respect to all such tendered
  Shares), together with a properly completed and duly executed Letter of
 
                                       6
<PAGE>
 
  Transmittal (or a manually signed facsimile thereof) with any required
  signature guarantees, or, in the case of a book-entry transfer, an Agent's
  Message, and any other documents, are received by the Depositary within
  three trading days after the date of execution of the Notice of Guaranteed
  Delivery. A "trading day" is any day on which the New York Stock Exchange,
  Inc. (the "NYSE") is open for business.
 
  The Notice of Guaranteed Delivery may be delivered by hand or transmitted by
telegram, facsimile transmission or mailed to the Depositary and must include
a guarantee by an Eligible Institution in the form set forth in the Notice of
Guaranteed Delivery.
 
  IN ALL CASES, SHARES SHALL NOT BE DEEMED VALIDLY TENDERED UNLESS A PROPERLY
COMPLETED AND DULY EXECUTED LETTER OF TRANSMITTAL (OR A MANUALLY SIGNED
FACSIMILE THEREOF) IS RECEIVED BY THE DEPOSITARY.
 
  Notwithstanding any other provision of this Offer to Purchase, payment for
Shares accepted for payment pursuant to the Offer will in all cases be made
only after timely receipt by the Depositary of certificates for (or a timely
Book-Entry Confirmation with respect to) such Shares, a Letter of Transmittal
(or a manually signed facsimile), properly completed and duly executed, with
any required signature guarantees and any other documents required by the
Letter of Transmittal (or in the case of a book-entry transfer, an Agent's
Message).
 
  Determination of Validity. All questions as to the form of documents and the
validity, eligibility (including time of receipt) and acceptance for payment
of any tender of Shares pursuant to any of the procedures described above will
be determined by Purchaser in its sole discretion, which determination shall
be final and binding on all parties. Purchaser reserves the absolute right to
reject any or all tenders of Shares determined not to be in proper form or the
acceptance of or payment for which may, in the opinion of Purchaser's counsel,
be unlawful. Purchaser also reserves the absolute right to waive any defect or
irregularity in any tender of any Shares of any particular Stockholder whether
or not similar defects or irregularities are waived in the case of other
Stockholders. Purchaser's interpretation of the terms and conditions of the
Offer (including the Letter of Transmittal and its instructions) will be final
and binding on all parties. No tender of Shares will be deemed to have been
validly made until all defects and irregularities have been cured or waived.
None of Parent, Purchaser, the Dealer Manager, the Depositary, the Information
Agent or any other person will be under any duty to give notification of any
defects or irregularities in tenders or incur any liability for failure to
give any such notification.
 
  Backup Federal Income Tax Withholding. To prevent backup federal income tax
withholding of 31% of the payments made to Stockholders with respect to the
purchase price of Shares purchased pursuant to the Offer or the Merger, a
Stockholder must provide the Depositary with his or her correct taxpayer
identification number ("TIN") and certify that he or she is not subject to
backup federal income tax withholding by completing the substitute Form W-9
included in the Letter of Transmittal. See Instruction 10 of the Letter of
Transmittal and Section 5 below.
 
  A tender of Shares pursuant to any of the procedures described above will
constitute the tendering Stockholder's acceptance of the terms and conditions
of the Offer, as well as the tendering Stockholder's representation and
warranty to Purchaser that (i) the Stockholder has a net long position in the
Shares being tendered, within the meaning of Rule 14e-4 under the Exchange
Act, and (ii) the tender of the Shares complies with Rule 14e-4. It is a
violation of Rule 14e-4 for a person, directly or indirectly, to tender Shares
for his or her own account, unless, at the time of tender, the person so
tendering (i) has a net long position equal to or greater than the amount of
(a) Shares tendered, or (b) other securities immediately convertible into or
exchangeable or exercisable for the Shares tendered and that person will
acquire the Shares for tender by conversion, exchange or exercise, and (ii)
will cause Shares to be delivered in accordance with the terms of the Offer.
Rule 14e-4 provides a similar restriction applicable to the tender or
guarantee of a tender on behalf of another person. Purchaser's acceptance for
payment of Shares tendered pursuant to the Offer will constitute a binding
agreement between the tendering Stockholder and Purchaser upon the terms and
conditions of the Offer.
 
                                       7
<PAGE>
 
  Appointment as Proxy. By executing a Letter of Transmittal, a tendering
Stockholder irrevocably appoints designees of Purchaser as his or her
attorneys-in-fact and proxies, with full power of substitution, in the manner
set forth in the Letter of Transmittal, to the full extent of the
Stockholder's rights with respect to the Shares tendered by the Stockholder
and purchased by Purchaser and with respect to any and all other Shares or
other securities issued or issuable in respect of those Shares, on or after
the date of the Offer. All such powers of attorney and proxies will be
considered coupled with an interest in the tendered Shares. Such appointment
will be effective when, and only to the extent that, Purchaser accepts the
Shares for payment. Upon acceptance for payment, all prior powers of attorney
and proxies given by the Stockholder with respect to the Shares (and any other
Shares or other securities so issued in respect of such purchased Shares) will
be revoked, without further action, and no subsequent powers of attorney and
proxies may be given (and, if given, will not be deemed effective) by the
Stockholder. The designees of Purchaser will be empowered to exercise all
voting and other rights of the Stockholder with respect to such Shares (and
any other Shares or securities so issued in respect of such purchased Shares)
as they in their sole discretion may deem proper, including, without
limitation, in respect of any annual or special meeting of the Stockholders,
or any adjournment or postponement of any such meeting, or in connection with
any action by written consent in lieu of any such meeting or otherwise
(including any such meeting or action by written consent to approve the
Merger). Purchaser reserves the absolute right to require that, in order for
Shares to be validly tendered, immediately upon Purchaser's acceptance for
payment of the Shares, Purchaser must be able to exercise full voting and
other rights with respect to the Shares, including voting at any meeting of
Stockholders then scheduled.
 
  4. WITHDRAWAL RIGHTS
 
  Tenders of Shares made pursuant to the Offer are irrevocable, except as
otherwise provided in this Section 4. Shares tendered pursuant to the Offer
may be withdrawn pursuant to the procedures set forth below at any time prior
to the Expiration Date and, unless theretofore accepted for payment and paid
for by Purchaser pursuant to the Offer, may also be withdrawn at any time
after Saturday, June 13, 1998. If Purchaser extends the Offer, is delayed in
its purchase of or payment for Shares or is unable to purchase or pay for
Shares for any reason, then, without prejudice to the rights of Purchaser,
tendered Shares may be retained by the Depositary on behalf of Purchaser and
may not be withdrawn, except to the extent that tendering Stockholders are
entitled to withdrawal rights as set forth in this Section 4. The reservation
by Purchaser of the right to delay the acceptance or purchase of or payment
for Shares is subject to the provisions of Rule 14e-1(c) under the Exchange
Act, which requires Purchaser to pay the consideration offered or return
Shares deposited by or on behalf of Stockholders promptly after the
termination or withdrawal of the Offer.
 
  For a withdrawal to be effective, a written, telegraphic or facsimile
transmission notice of withdrawal must be timely received by the Depositary at
one of its addresses set forth on the back cover of this Offer to Purchase.
Any such notice of withdrawal must specify the name of the persons who
tendered the Shares to be withdrawn, the number of Shares to be withdrawn and
the name of the registered holder, if different from that of the person who
tendered the Shares. If certificates evidencing Shares have been delivered or
otherwise identified to the Depositary, then, prior to the physical release of
the certificates, the tendering Stockholder must also submit to the Depositary
the serial numbers shown on the particular certificates that evidence the
Shares to be withdrawn, and the signature on the notice of withdrawal must be
guaranteed by an Eligible Institution (except in the case of Shares tendered
for the account of an Eligible Institution). If Shares have been tendered
pursuant to the procedure for book-entry transfer set forth in Section 3
above, the notice of withdrawal must also specify the name and number of the
account at the applicable Book-Entry Transfer Facility to be credited with the
withdrawn Shares and otherwise comply with such Book-Entry Transfer Facility's
procedures.
 
  All questions as to the form and validity (including time of receipt) of
notices of withdrawal will be determined by Purchaser, in its sole discretion,
whose determination will be final and binding on all parties. No withdrawal of
Shares will be deemed to have been properly made until all defects and
irregularities have been cured or waived. None of Parent, Purchaser, the
Dealer Manager, the Depositary, the Information Agent or any other person will
be under any duty to give notification of any defects or irregularities in any
notice of withdrawal or incur any liability for failing to give such
notification.
 
                                       8
<PAGE>
 
  Any Shares properly withdrawn will be deemed not validly tendered for
purposes of the Offer, but may be tendered at any subsequent time prior to the
Expiration Date by following any of the procedures described in Section 3
above.
 
  5. CERTAIN FEDERAL INCOME TAX CONSEQUENCES OF THE OFFER AND THE MERGER
 
  The following is a summary of the principal federal income tax consequences
of the Offer and the Merger to Stockholders whose Shares are purchased
pursuant to the Offer or whose Shares are converted into the right to receive
the Merger Consideration in the Merger (including any cash amounts received by
dissenting Stockholders pursuant to the exercise of appraisal rights). This
discussion is based upon the provisions of the Internal Revenue Code of 1986,
as amended (the "Code"), the applicable Treasury Regulations promulgated and
proposed thereunder, judicial authority and administrative rulings and
practice. Legislative, judicial or administrative changes or interpretations
are subject to change, possibly on a retroactive basis, at any time and
therefore could alter or modify the statements and conclusions set forth
below. This discussion assumes that the Stockholders hold the Shares as
"capital assets" within the meaning of Section 1221 of the Code (i.e.,
property held for investment). This discussion does not address all aspects of
federal income taxation that may be relevant to a particular Stockholder in
light of such Stockholder's personal investment circumstances, or those
Stockholders subject to special treatment under the federal income tax laws
(for example, life insurance companies, tax-exempt organizations, foreign
corporations and nonresident alien individuals) or to Stockholders who
acquired their Shares through the exercise of employee stock options or other
compensation arrangements. In addition, the discussion does not address any
aspect of foreign, state, local or estate and gift taxation that may be
applicable to a Stockholder.
 
  Consequences of the Offer and the Merger to Stockholders. The receipt of the
Offer Price and the Merger Consideration will be a taxable transaction for
federal income tax purposes (and also may be a taxable transaction under
applicable state, local and other income tax laws). In general, for federal
income tax purposes, a Stockholder will recognize gain or loss equal to the
difference between his or her adjusted tax basis in the Shares sold pursuant
to the Offer or converted to cash in the Merger and the amount of cash
received therefor. Gain or loss must be determined separately for each block
of Shares (i.e., Shares acquired at the same cost in a single transaction)
sold pursuant to the Offer or converted to cash in the Merger. For federal
income tax purposes, such gain or loss will be a capital gain or loss if the
Shares are a capital asset in the hands of the stockholder. Capital gains of
individuals, estates and trusts generally are subject to a maximum federal
income tax rate of (i) 39.6% if, at the time the Purchaser accepts the Shares
for payment pursuant to the Offer or the effective date of the Merger, as the
case may be, the Stockholder held the Shares for not more than one year, (ii)
28% if the Stockholder held such Shares for more than one year but not more
than 18 months at such time, and (iii) 20% if the Stockholder held such Shares
for more than 18 months at such time. Capital gains of corporations generally
are taxed at the federal income tax rates applicable to ordinary income.
Ordinary income is taxable at a maximum rate of 39.6% for individuals and 35%
for corporations. There are significant limitations on the deductibility of
capital losses by individuals and corporations. Capital losses can offset
capital gains on a dollar-for-dollar basis and, in the case of an individual
Stockholder, capital losses in excess of capital gains can be deducted to the
extent of $3,000 annually. An individual can carry forward unused capital
losses indefinitely. A corporation can utilize capital losses only to offset
capital gain income; a corporation's unused capital losses can be carried back
three years and forward five years.
 
  The receipt of cash pursuant to a Stockholder's exercise of Option rights or
of dissenter's rights in connection with the Merger will be a taxable
transaction for federal income tax purposes. Any Stockholders considering the
exercise of Option rights or of dissenter's rights are urged to consult their
individual tax advisors regarding the tax consequences of the exercise of such
rights.
 
  Backup Tax Withholding. Under the Code, a Stockholder may be subject, under
certain circumstances, to "backup withholding" at a 31% rate with respect to
payments made in connection with the Offer or the Merger. Backup withholding
generally applies if the Stockholder (i) fails to furnish his or her Social
Security Number or employer identification number ("TIN"), (ii) furnishes an
incorrect TIN, (iii) fails properly to report interest or
 
                                       9
<PAGE>
 
dividends or (iv) under certain circumstances, fails to provide a certified
statement, signed under penalties of perjury, that the TIN provided is his or
her correct number and that he or she is not subject to backup withholding.
Backup withholding is not an additional tax but merely an advance payment,
which may be refunded to the extent it results in an overpayment of tax.
Certain persons generally are exempt from backup withholding, including
corporations and financial institutions. Certain penalties apply for failure
to furnish correct information and for failure to include the reportable
payments in income. Each Stockholder should consult with his or her own tax
advisor as to his or her qualifications for exemption from withholding and the
procedure for obtaining such exemption.
 
  THE FEDERAL INCOME TAX DISCUSSION SET FORTH ABOVE IS INCLUDED FOR GENERAL
INFORMATION PURPOSES ONLY. STOCKHOLDERS SHOULD CONSULT THEIR OWN TAX ADVISORS
TO DETERMINE THE FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES OF THE
OFFER AND THE MERGER TO THEM IN VIEW OF THEIR OWN PARTICULAR CIRCUMSTANCES.
 
  6. PRICE RANGE OF THE SHARES; DIVIDENDS ON THE SHARES
 
  According to the Company's Annual Report on Form 10-K for the fiscal year
ended January 31, 1997 (the "Company 10-K"), the principal trading market for
the Shares is The Nasdaq National Market ("Nasdaq"), where the trading symbol
is "DART." The following table sets forth, for the periods indicated, the high
and low intraday sales prices per Share (and, for periods prior to February
17, 1998, the predecessor shares of the Company's Class A Common Stock), as
reported by Nasdaq:
 
<TABLE>

   April 30, 1997.............................................. $108.00  $ 88.50
   July 31, 1997...............................................  112.875   96.50
   October 31, 1997............................................  118.00    99.25
   January 31, 1998............................................  119.50   104.00
</TABLE>
 
  On April 8, 1998, the last full trading day before the public announcement
by Parent and the Company of the execution of the Merger Agreement and
Purchaser's intention to commence the Offer, the last reported sale price on
Nasdaq was $140.00 per Share. On April 14, 1998, the last full trading day
before the commencement of the Offer, the last reported sale price on Nasdaq
was $161.00 per Share. STOCKHOLDERS ARE URGED TO OBTAIN CURRENT MARKET
QUOTATIONS FOR THE SHARES.
 
  According to published financial sources, the Company has paid a quarterly
dividend of $0.0333 on the Shares for each of the periods presented above.
 
  7. EFFECT OF THE OFFER ON THE MARKET FOR THE SHARES, STOCK EXCHANGE LISTING,
EXCHANGE ACT REGISTRATION AND STATUS AS MARGIN SECURITIES
 
  The purchase of Shares pursuant to the Offer will reduce the number of
Shares that might otherwise trade publicly and may reduce the number of
holders of Shares, which could adversely affect the liquidity and market value
of the remaining Shares held by Stockholders other than Purchaser. Purchaser
cannot predict whether the reduction in the number of Shares that might
otherwise trade publicly would have an adverse or beneficial effect on the
market price for, or marketability of, the Shares or whether such reduction
would cause future market prices to be greater or less than the Offer Price.
 
                                      10
<PAGE>
 
  Depending upon the number of Shares purchased pursuant to the Offer, the
Shares may no longer meet the requirements of Nasdaq for continued listing and
may, therefore, be delisted from such exchange. According to Nasdaq's
published guidelines, Nasdaq would consider delisting the Shares if, among
other things, (i) the number of Shares held by persons who are not officers,
directors or beneficial owners of 10% of the outstanding Shares is less than
750,000, (ii) the market value of such Shares is less than $5.0 million, (iii)
less than 400 shareholders hold a block of 100 Shares or more, (iv) the number
of market makers making a market in the Shares is less than two or (v) the net
tangible assets of the Company is less than $4.0 million. The Company has
represented that, as of April 6, 1998, there were 1,202,502 Shares issued and
outstanding and no Shares held in the Company's treasury. If, as a result of
the purchase of Shares pursuant to the Offer, the Shares no longer meet the
requirements of Nasdaq for continued listing and the listing of Shares is
discontinued, the market for the Shares could be adversely affected.
 
  If Nasdaq were to delist the Shares (which Purchaser intends to cause the
Company to seek if it acquires control of the Company and the Shares no longer
meet Nasdaq listing requirements), it is possible that the Shares would trade
on a securities exchange or in the over-the-counter market and that price
quotations for the Shares would be reported by such exchange or other sources.
The extent of the public market for the Shares and availability of such
quotations would, however, depend upon such factors as the number of holders
and/or the aggregate market value of the publicly held Shares at such time,
the interest in maintaining a market in the Shares on the part of securities
firms, the possible termination of registration of the Shares under the
Exchange Act and other factors.
 
  The Shares are currently registered under the Exchange Act. Such
registration may be terminated upon application of the Company to the
Commission if the Shares are neither listed on a national securities exchange
nor held by 300 or more holders of record. Termination of the registration of
the Shares under the Exchange Act would substantially reduce the information
required to be furnished by the Company to holders of Shares and to the
Commission and would make certain of the provisions of the Exchange Act, such
as the short-swing profit recovery provisions of Section 16(b), the
requirement of furnishing a proxy statement pursuant to Section 14(a) in
connection with a stockholders' meeting and the related requirement of an
annual report to stockholders and the requirements of Rule 13e-3 under the
Exchange Act with respect to "going private" transactions, no longer
applicable to the Company. Furthermore, "affiliates" of the Company and
persons holding "restricted securities" of the Company may be deprived of the
ability to dispose of such securities pursuant to Rule 144 promulgated under
the Securities Act of 1933, as amended (the "Securities Act"). If registration
of the Shares under the Exchange Act were terminated, the Shares would no
longer be "margin securities" or eligible for inclusion on Nasdaq. Purchaser
intends to seek to cause the Company to terminate registration of the Shares
under the Exchange Act as soon after consummation of the Offer as the
requirements for termination of registration of the Shares are met.
 
  The Shares are currently "margin securities" under the regulations of the
Board of Governors of the Federal Reserve System (the "Federal Reserve
Board"), which has the effect, among other things, of allowing brokers to
extend credit on the collateral of such Shares. Depending upon factors similar
to those described above regarding listing and market quotations, upon
consummation of the Offer the Shares might no longer constitute "margin
securities" for the purposes of the Federal Reserve Board's margin regulations
and, therefore, could no longer be used as collateral for loans made by
brokers.

  Certain Company Projections. During the course of discussions between Parent
and the Company that led to the execution of the Merger Agreement (see Section
11 below), the Company discussed with representatives of Parent certain
limited non-public business and financial information about the Company.
Subsequently, the Company provided Parent with certain limited written, non-
public business and financial information concerning Shoppers. The written
information provided to Parent included Shoppers' budgeted fiscal 1999 sales
and earnings before interest, taxes, depreciation and amortization ("EBITDA")
of $906.6 million and $41.6 million, respectively, compared to the Company's
estimate of fiscal 1998 sales and EBITDA for Shoppers of $855.8 million and
$38.6 million, respectively.
 
  THE COMPANY DOES NOT AS A MATTER OF COURSE MAKE PUBLIC ANY PROJECTIONS AS TO
FUTURE PERFORMANCE OR EARNINGS, AND THE PROJECTIONS SET FORTH ABOVE ARE
INCLUDED IN THIS OFFER TO PURCHASE ONLY BECAUSE THE INFORMATION WAS PROVIDED
TO PURCHASER AND PARENT. THE PROJECTIONS WERE NOT PREPARED WITH A VIEW TO
PUBLIC DISCLOSURE OR FOR COMPLIANCE WITH THE PUBLISHED GUIDELINES OF THE
COMMISSION OR THE GUIDELINES ESTABLISHED BY THE AMERICAN INSTITUTE OF
CERTIFIED PUBLIC ACCOUNTANTS REGARDING PROJECTIONS OR FORECASTS. THE COMPANY
HAS ADVISED PURCHASER AND PARENT THAT ITS INTERNAL FINANCIAL FORECASTS (UPON
WHICH THE PROJECTIONS PROVIDED TO PARENT WERE BASED IN PART) ARE, IN GENERAL,
PREPARED SOLELY FOR INTERNAL USE AND CAPITAL BUDGETING AND OTHER MANAGEMENT
DECISIONS, AND ARE SUBJECTIVE IN MANY RESPECTS AND THUS SUSCEPTIBLE TO

DEVELOPMENTS. NONE OF THE COMPANY, PURCHASER OR PARENT OR THEIR RESPECTIVE
FINANCIAL ADVISORS OR ANY OF THEIR RESPECTIVE DIRECTORS OR OFFICERS ASSUMES
ANY RESPONSIBILITY FOR THE ACCURACY OF ANY OF THE PROJECTIONS. BECAUSE THE
ESTIMATES AND ASSUMPTIONS UNDERLYING THE PROJECTIONS ARE INHERENTLY SUBJECT TO
SIGNIFICANT ECONOMIC AND COMPETITIVE UNCERTAINTIES AND CONTINGENCIES THAT ARE
DIFFICULT OR IMPOSSIBLE TO PREDICT ACCURATELY AND ARE BEYOND THE COMPANY'S,
PURCHASER'S AND PARENT'S CONTROL, THERE CAN BE NO ASSURANCE THAT THE
PROJECTIONS WILL BE REALIZED. ACCORDINGLY, IT IS EXPECTED THAT THERE WILL BE
DIFFERENCES BETWEEN ACTUAL AND PROJECTED RESULTS, AND ACTUAL RESULTS MAY BE
MATERIALLY HIGHER OR LOWER THAN THOSE PROJECTED.

  9. CERTAIN INFORMATION CONCERNING PURCHASER AND PARENT
 
  Purchaser, a Delaware corporation, was organized to acquire all of the
outstanding Shares pursuant to the Offer and has not conducted any unrelated

  Parent is the leading wholesale food distributor in its Mid-Atlantic
operating region and the fourth largest wholesale food distributor in the
United States. Parent's Wholesale Division supplies a comprehensive selection
of national brand and private label grocery products, dairy products, frozen
foods, fresh produce items, meats, delicatessen and bakery products and non-
food items primarily from two modern, highly efficient distribution centers.
Parent's distribution centers are strategically located within its operating
region and have capacity to accommodate additional growth. The Wholesale
Division services more than 1,400 retail grocery stores, including leading
regional chains and smaller independent retailers throughout the Mid-Atlantic
region, offering its customers a dependable supply and prompt delivery of over
37,000 grocery and non-grocery items at competitive prices. With the recent
completion of the Farm Fresh Acquisition (as defined below), Parent's Retail
Grocery Division operates sixty-two retail grocery stores, primarily under the
Farm Fresh and Metro tradenames. On a pro forma basis, after giving effect to
the Farm Fresh Acquisition, Parent's Wholesale Division and Retail Grocery
Division would have accounted for approximately 75.5% and 24.5%, respectively,
of Parent's sales (before intersegment sales eliminations) during its fiscal
year ended May 3, 1997.
 
WHOLESALE DIVISION
 
  Parent's management believes that, as a result of its strategic focus on
cost control, logistics and distribution, Parent is now one of the most
efficient wholesale food distributors in the United States. Over the past five
fiscal years, Parent has reduced and controlled costs by (i) capitalizing on
its size to improve its purchasing power, (ii) rationalizing product
purchasing and pricing systems, (iii) implementing a pricing system that
encourages efficient use of Parent's services and (iv) instituting
productivity-based incentives for distribution center associates. Over the
same period, Parent has significantly improved the efficiency of its logistics
and distribution functions by, among other things, implementing state-of-the-
art computer systems related to purchasing, inventory management and fleet
loading and routing. These improvements have permitted Parent to drive
substantially increased volume through its distribution system and to increase
capacity utilization significantly, thereby benefiting from its operating
leverage.
 
  Parent's Wholesale Division has increased sales to existing customers and
attracted new customers by using Parent's purchasing power, low cost structure
and efficient distribution system to provide products to its customers at the
lowest available prices, while offering its customers a wide variety of
services to support their competitive position. The Wholesale Division has
benefitted from the growth of the leading regional chains and smaller
independent retail grocers that it serves.
 
  Parent's Wholesale Division consists of: Richfood/Virginia, which operates a
1.3 million square foot distribution center located in Richmond, Virginia;
Richfood/Pennsylvania, which operates two distribution facilities totaling
approximately 1.0 million square feet in Harrisburg, Pennsylvania, and a
150,000 square foot produce distribution center in Norristown, Pennsylvania;
and the Richfood Dairy, which is the largest fluid dairy in Virginia
consisting of a 65,000 square foot facility capable of processing and
packaging over 800,000 gallons per week of milk and other dairy products,
fruit juices, bottled water and related items.

RETAIL DIVISION
 
  Parent's Retail Grocery Division, which was acquired in connection with its
acquisition of Super Rite Corporation in October 1995, operates fifteen 45,000
to 60,000 square foot "superstores" under the Metro tradename, and two smaller
traditional supermarkets under the Basics tradename, in the metropolitan
Baltimore, Maryland and Dover, Delaware markets. In addition, on March 4,
1998, Parent acquired substantially all of the assets and assumed certain
liabilities of Farm Fresh, Inc. ("Farm Fresh"), a privately held retail
supermarket chain headquartered in Norfolk, Virginia (the "Farm Fresh
Acquisition"). Farm Fresh currently operates 45 supermarkets in the Hampton
Roads, metropolitan Richmond and Shenandoah Valley areas of Virginia primarily
under two distinct tradenames and formats: (i) Farm Fresh, thirty-three
traditional supermarkets averaging approximately 33,000 square feet, offering
a full line of grocery items and selected specialty departments; and (ii) Rack
& Sack, eleven super warehouse stores averaging approximately 55,000 square
feet, featuring price sensitive grocery items at discounted prices. The
remaining store is operated under a separate name and format. According to a
May 1997 study by Dakota Worldwide Corporation, Farm Fresh is the second
largest supermarket chain in the Hampton Roads region of Virginia (consisting
of the cities of Norfolk, Hampton, Chesapeake and Virginia Beach), its
principal operating area, commanding a 34.5% market share.
 
  The Farm Fresh Acquisition represents a further step in Parent's ongoing
strategy of pursuing strategic acquisitions in its Mid-Atlantic operating
region. Parent expects that it will be able to leverage its core competencies
in logistics and distribution to serve the Farm Fresh stores effectively,
while increasing efficiency through the utilization of excess warehouse space.
In addition, Parent's ownership of the Farm Fresh stores will result in
increased purchasing power with retail vendors, which should benefit customers
of the Company's Wholesale Division as well as Parent's own Metro and Basics
retail stores. As a result of the acquisition, Parent's Wholesale Division
will also maintain its existing business with Farm Fresh, formerly its third
largest customer, and is expected to gain incremental business via the
replacement of a portion of Farm Fresh's supply that was previously self-
distributed.
 
STRATEGIC ACQUISITIONS
 
  Parent's substantial growth since 1990 is largely attributable to strategic
acquisitions. Parent considers strategic acquisition targets that are well
run, established operations, with modern facilities and the capacity to
accommodate anticipated growth, and that complement Parent's existing
operations and geographic service area.
 
  Parent is a Virginia corporation formed in 1987. Parent's principal
executive offices are located at 4860 Cox Road, Suite 300, Glen Allen,
Virginia 23060, telephone (804) 915-6000.
 
  Except as described in this Offer to Purchase, during the last five years,
none of Purchaser, Parent or, to the best knowledge of Purchaser and Parent,
any of the persons listed in Schedule I hereto (i) has been convicted in a
criminal proceeding (excluding traffic violations and similar misdemeanors),
or (ii) was a party to a civil proceeding of a judicial or administrative body
of competent jurisdiction and as a result of such proceeding was or is subject
to a judgment, decree or final order enjoining future violations of, or
prohibiting activities subject to, federal or state securities laws or finding
any violation of such laws. The name, business address, present principal
occupation or employment, five-year employment history and citizenship of each
director and executive officer of Purchaser and Parent are set forth in
Schedule I.

  Except as described in this Offer to Purchase, (i) none of Purchaser, Parent
or, to the best knowledge of Purchaser and Parent, any of the persons listed
in Schedule I or any associate or majority-owned subsidiary of any such
person, beneficially owns or has a right to acquire any equity security of the
Company, and (ii) none of Purchaser, Parent or, to the best knowledge of

the respective directors, executive officers or subsidiaries of any of the
foregoing, has effected any transaction in any equity security of the Company

  10. SOURCE AND AMOUNT OF FUNDS
 
  Neither the Offer nor the Merger is conditioned upon any financing
arrangements. Purchaser estimates that the total amount of funds required to
consummate the Offer and the Merger, to pay related fees and expenses and to
pay outstanding indebtedness of the Company that may become due as a result of
the Offer and the Merger is approximately $228 million. Purchaser expects to
obtain these funds from Parent by means of a capital contribution, loan or
combination thereof. Parent, in turn, expects to obtain these funds from
available cash, marketable securities and borrowing capacity under its
committed credit facilities.
 
  In contemplation of the Offer, Parent entered into a commitment letter with
First Union National Bank ("First Union") pursuant to which First Union
agreed, on the terms and subject to the conditions set forth therein, to
provide credit facilities to the Parent in an aggregate amount of $450
million, $250 million of which will be a five-year revolving credit facility
and $200 million of which will be an eighteen-month term loan. Borrowings
under the facilities will initially bear interest at a variable rate per annum
equal to LIBOR plus 1%. The representations, warranties and covenants set
forth in the credit facilities will be substantially similar to those set
forth in Parent's existing credit facilities with First Union, as lender and
administrative agent for a syndicate of banks, except that the new credit
facilities will be secured by a pledge of the stock of certain subsidiaries of
Parent and unconditionally guaranteed by certain subsidiaries of Parent, which
pledges and guarantees will be released at such time as Parent's senior debt
rating is reaffirmed as investment grade. The new credit facilities will
contain provisions requiring early repayment of the term loan with the net
proceeds of new offerings of equity securities or senior debt by Parent, and
with the net proceeds of any sale of the Company's interests in Trak, Crown or
certain real estate assets, which dispositions occur after consummation of the
Merger. Parent anticipates repaying a portion of the new credit facilities
with the net proceeds of any such sales, as well as with the net proceeds of a
possible equity offering.
 
  11. BACKGROUND OF THE OFFER
 
  Since late 1996, Parent has been interested in acquiring Shoppers, a retail
supermarket chain which currently operates 37 price impact grocery stores in
the Greater Washington, D.C. market. Prior to February 1997, each of the
Company and Mr. Kenneth Herman, one of Shoppers' founders and its former Chief
Executive Officer, owned 50% of the outstanding common stock of Shoppers.
Under the "buy-sell" provisions of a stockholders agreement, as amended,
between the Company and Mr. Herman, each party had the right to offer to sell
its interest in Shoppers to the other at a specified price; if the offeree did
not purchase the offered interest at the specified price, the offeror was
obligated to purchase (and the offeree was obligated to sell) the offeree's
interest at such price.
 
  In October 1996, representatives of Parent and Mr. Herman entered into
discussions regarding Parent's purchase of all of the outstanding equity
interests in Shoppers through an offer to Mr. Herman that would extend to the
shares of Shoppers common stock owned by the Company by virtue of the buy-sell
provisions of the stockholders agreement. In November 1996, Parent delivered a
preliminary expression of interest to representatives of Mr. Herman and
commenced a due diligence investigation related to Shoppers' business and
assets. On December 16, 1996, the Company announced that it had delivered an
offer to Mr. Herman under the buy-sell provisions of the stockholders
agreement and, on February 6, 1997, the Company purchased Mr. Herman's 50%
interest in Shoppers and Shoppers became a wholly-owned subsidiary of the
Company.
 
  In March 1997, representatives of the Company contacted several prospective
buyers of Shoppers, including Parent, to ascertain their interest in a
possible acquisition of Shoppers. On April 15, 1997, Parent delivered its
preliminary expression of interest to representatives of the Company
reflecting a preliminary valuation of approximately $300 million (less assumed
debt and assumed capital leases) for substantially all of the assets of
Shoppers. Following receipt of such expression of interest, the Company
determined not to proceed with a possible sale of Shoppers at that time.
 
  Parent remained interested in a possible acquisition of Shoppers and, in
August and September 1997, began an evaluation of a possible acquisition of
all of the stock, or substantially all of the assets, of the Company. At a
 
                                      17
<PAGE>
 
meeting held on November 13, 1997, Parent's Board of Directors authorized
Parent's management to contact senior management of the Company to explore a
possible business combination. In early December 1997, Mr. John E. Stokely,
President, Chief Executive Officer and a Director of Parent, called Mr.
Richard B. Stone, the Acting Chief Executive Officer and a Director of the
Company, and requested a meeting. On December 17, 1997, Mr. Stokely met with
Mr. Stone and Mr. William White, President of Shoppers, to discuss the
potential for and the feasibility of a business combination involving Parent
and the Company. No decisions or commitments were made at that meeting. Over
the remainder of December 1997 and the first week of January 1998, Messrs.
Stokely and Stone had several additional telephone conversations regarding the
process that the Company would follow in the event it decided to request and
evaluate any possible expression of interest from Parent.
 
  During January 1998, DLJ began informally advising the Company with respect
to the possible business combination with the Company. On February 3, 1998,
Parent and the Company entered into a confidentiality agreement governing
Parent's due diligence investigation of the business and assets of the
Company. Because the Company was still completing the final transactions
connected to settlements of certain litigation with members of the Haft
family, and was in the process of completing changes to its corporate
governance structure, the Company did not pursue discussions about terms of a
potential agreement and no formal diligence review process was begun at that
time.
 
  On February 4, 1998, management of Parent, together with Parent's legal
advisors and representatives of DLJ, made presentations to Parent's Board of
Directors regarding a possible business combination between Parent and the
Company.
 
  In early February 1998, a group of investors advised the Company of its
desire to acquire Shoppers from the Company for $360 million in cash. The
group's proposed offer was reported in the Washington Post on February 11,
1998. The letter did not indicate any source of financing and was contingent
upon a due diligence review. The letter also did not address how various
intercompany liabilities would be handled.
 
  By letter delivered to the Company on February 12, 1998, Mr. Stokely advised
Mr. Stone of Parent's continued interest in acquiring Shoppers at a value
superior to the group's purported proposal. Mr. Stokely also advised Mr. Stone
that Parent was prepared to make an offer to acquire all of the Company,
rather than Shoppers alone, permitting the Company's Board of Directors to
maximize value for the Company's stockholders in a single transaction. Later
on February 12, 1998, Messrs. Stokely and Stone had a telephone conversation
to clarify certain aspects of Parent's letter, and Parent held an informal
telephonic meeting of its Board of Directors concerning the status of
discussions with the Company.
 
  On February 13, 1998, Mr. Stone called Mr. Stokely to discuss the
preliminary materials related to the Company's business that would be required
by Parent to evaluate a business combination involving all of the Company.
 
  On February 26, 1998, Parent formally retained DLJ as its financial advisor
in connection with the possible business combination with the Company.
 
  On March 2, 1998, Mr. Stokely and Mr. John C. Belknap, Executive Vice
President and Chief Financial Officer of Parent, met with Senator Stone and
Mr. Harry Linowes, a Director of the Company, to discuss the possible business
combination. Their discussion included exploration of the rationale for the
possible transaction and the expected benefits to the constituent companies
and their respective stockholders. Mr. Stokely advised Messrs. Stone and
Linowes that, based on its preliminary review of materials available at that
time, Parent was interested in acquiring the Company in a stock-for-stock
merger valued by Parent at $147.00 per share of Company common stock. No
agreements were reached at that meeting.
 
  On March 4, 1998, Mr. Stone called Mr. Stokely and discussed the possibility
of receiving written confirmation of Parent's expression of interest, and the
timing for disclosure of any such written expression of
 
                                      18
<PAGE>
 
interest. Later that day, Mr. Stokely advised Mr. Stone, in writing, of
Parent's view that any expression of interest must be confidential and include
a termination date, and would be subject to the completion of due diligence.
In a telephone conversation later on March 4, 1998, Messrs. Stone and Stokely
agreed that Parent would be afforded an opportunity to conduct a due diligence
review of the business and assets of the Company before submitting a written
expression of interest.
 
  From March 9 through March 22, 1998, representatives of Parent, its legal
and accounting advisors, and DLJ conducted an on-site due diligence review of
the business and assets of the Company and its significant subsidiaries.
 
  On March 23, 1998, representatives of Parent, its legal advisors and DLJ met
at the Company's headquarters with the Company's Board of Directors, the
Company's legal advisors and representatives of Wasserstein. Parent delivered
and reviewed a letter proposing a stock-for-stock merger of the Company with a
subsidiary of Parent, valued by Parent at $147.00 per share of Company common
stock, together with a draft agreement to effect such transaction.
 
  From March 23, 1998, through April 2, 1998, representatives of DLJ and
Wasserstein took part in a number of telephonic discussions regarding the
valuation and form of consideration contemplated in Parent's bid. On April 2,
1998, representatives of Wasserstein indicated their belief that the Board of
Directors of the Company might view favorably an offer by Parent to acquire
all of the Company's common stock through a tender offer and second step
merger, each at no less than $157.00 per share in cash. DLJ relayed this
information to Parent and, after informal discussions with most members of
Parent's Board of Directors, Mr. Stokely authorized DLJ to advise Wasserstein
that Parent was prepared to explore a possible all-cash transaction at $157.00
per share of Company common stock.
 
  Over the course of April 3, 1998, representatives of DLJ and Wasserstein had
several telephonic conversations related to the value and structure of
Parent's proposal, and the Boards of Directors of the Company and Parent held
separate telephonic meetings to consider the proposal. Wasserstein informed
the Company's Board that Parent had increased its offer to $157.00 in cash per
share of Company common stock, and the Company's Board instructed Wasserstein
to seek a further increase in price. After further discussions, management of
Parent instructed DLJ to advise Wasserstein that Parent would raise its bid to
$160.00 in cash per share of Company common stock, if definitive documentation
could be executed promptly. Thereafter, representatives of Wasserstein advised
DLJ that the Company desired to negotiate and execute a definitive agreement
reflecting such value as soon as practicable.
 
  On the morning of Sunday, April 5, 1998, Parent's legal counsel provided a
draft Merger Agreement related to the proposed transaction to representatives
of the Company. From the evening of Sunday, April 5, through the morning of
Thursday, April 9, 1998, representatives of Parent, its legal advisors and DLJ
met daily either telephonically or in person with representatives of the
Company, its legal advisors and Wasserstein to negotiate and finalize the
Merger Agreement. On Monday, April 6, 1998, the Board of Directors of Parent
met and received presentations from its legal advisers and DLJ with respect to
the proposed transaction.
 
  On Tuesday, April 7, 1998, the Board of Directors of Parent met and received
additional information from Parent's legal advisers, and was advised that DLJ
was prepared to deliver its opinion that the proposed consideration to be paid
by Parent pursuant to the Merger Agreement was fair to Parent and its
shareholders from a financial point of view. At the conclusion of such
meeting, the Board of Directors of Parent unanimously approved the proposed
transaction, subject to certain authorized officers' satisfaction with the
resolution of the few remaining issues.
 
  In the morning and again in the late evening of April 8, 1998, the Board of
Directors of the Company met and received presentations from the Company's
legal advisers and Wasserstein. During the morning meeting, Wasserstein
advised the Board that it was prepared to deliver its opinion that the
proposed transaction was fair to the Company and its stockholders from a
financial point of view. At the conclusion of such meeting, the Board of
Directors of the Company unanimously approved the proposed transaction.
 
                                      19
<PAGE>
 
  The draft Merger Agreement was finalized over the evening of April 8 and the
early morning of April 9, 1998. The Merger Agreement was executed, and the
transaction was publicly announced, before the opening of business on April 9,
1998.
 
  12. PURPOSE OF THE OFFER AND THE MERGER; PLANS FOR THE COMPANY; THE MERGER
AGREEMENT; OTHER AGREEMENTS
 
 Purpose of the Offer and the Merger
 
  The purpose of the Offer and the Merger is to enable Purchaser to acquire,
in one or more transactions, control of the Company and the entire equity
interest in the Company. The Offer is intended to increase the likelihood that
the Merger will be completed promptly.
 
 Plans for the Company
 
  Parent intends, from time to time after completion of the Offer, to evaluate
and review the Company's operations and consider what, if any, changes would
be desirable in light of circumstances that then exist. Parent intends, as
soon as practicable following consummation of the Offer, to cause the Company
to divest its non-core assets, including its ownership of Trak, Crown and
Total Beverage. In addition, Parent intends, following consummation of the
Offer, to suspend the Company's practice of declaring regular quarterly
dividends. Except as noted in this Offer to Purchase, Purchaser and Parent
have no present plans or proposals that would result in an extraordinary
corporate transaction, such as a merger, reorganization, liquidation or sale
or transfer of a material amount of assets involving the Company or any
subsidiary or any other material changes in the Company's capitalization,
dividend policy, corporate structure, business or composition of its

 The Merger Agreement
 
  The following is a summary of the material terms of the Merger Agreement.
This summary is not a complete description of the terms and conditions of the
Merger Agreement and is qualified in its entirety by reference to the full
text of the Merger Agreement, which is incorporated by reference and a copy of
which has been filed with the Commission as an exhibit to the Schedule 14D-1.
The Merger Agreement may be examined, and copies obtained, as set forth in
Section 8 above.
 
  The Offer. The Merger Agreement provides for the commencement of the Offer.
Purchaser has expressly reserved the right to increase the price per Share
payable in the Offer or to make any other changes in the terms and conditions
of the Offer, except that without the prior written consent of the Company,
Purchaser has agreed that it will not (i) decrease or change the form of the
Offer Consideration or decrease the number of Shares sought pursuant to the
Offer, (ii) impose additional conditions to the Offer, (iii) extend the
Expiration Date of the Offer (except as required by law or the applicable
rules and regulations of the Commission and except that Purchaser (x) may
extend the Expiration Date of the Offer for up to ten (10) business days after
the initial Expiration Date if fewer than 90% of the Shares outstanding as of
such date have been tendered as of such date, so long as, in connection with
such extension, Purchaser irrevocably waives the conditions to the Offer
described in clauses (b), (c), (f), (g)(1) and (h) of Item 14 (Conditions to
the Offer) hereof, and (y) Purchaser shall extend the Offer from time to time
until June 30, 1998, if, and to the extent that, at the initial expiration of
the Offer, or any subsequent extension thereof, all conditions to the Offer
have not been satisfied or waived and the failure of a condition to be
satisfied is not due to the failure of the Company to fulfill any of its
obligations under the Merger Agreement, or (iv) amend any term of the Offer in
any manner adverse to Stockholders; provided, however, that, except as set
forth above, Purchaser may waive any condition to the Offer in its sole
discretion (other than the Minimum Condition); and provided, further, that the
Offer may be extended in connection with an increase in the consideration to
be paid pursuant to the Offer so as to comply with applicable rules and
regulations of the Commission. Assuming the prior satisfaction or waiver of
the conditions to the Offer, Purchaser will accept for payment, and pay for,
in accordance with the terms of the Offer, all Shares validly tendered and not
withdrawn pursuant to the Offer as soon as practicable after the Expiration
Date thereof.

  Payment for Shares. Prior to the Effective Time, Parent will deposit or
shall cause to be deposited with the Depositary in a separate fund established
for the benefit of the holders of Shares, for payment in accordance with the
Merger Agreement (the "Payment Fund"), immediately available funds in amounts
necessary to make the payments pursuant to the Merger Agreement to holders of
Shares (other than the Company or any wholly-owned subsidiary of the Company
or Parent, Purchaser or any other wholly-owned Subsidiary of Parent, or
holders of Dissenting Shares (as defined below)). The Depositary shall,
pursuant to irrevocable instructions, pay the Merger Consideration out of the
Payment Fund. Parent shall provide or cause to be provided to Purchaser all of
the funds necessary to purchase any Shares that Purchaser becomes obligated to
purchase pursuant to the Offer.
 
  Any portion of the Payment Fund which remains undistributed to the holders
of Shares for one year after the Effective Time shall be delivered to the
Company, upon demand, and any holders of Shares who have not theretofore
complied with the Merger Agreement and the Instructions set forth in the
Letter of Transmittal mailed to such holder after the Effective Time shall
thereafter look only to the Company for payment of the Merger Consideration to
which they are entitled; provided that if, but only if, the Company shall have
defaulted in its obligation to make such payment within a reasonable period of
time after receipt of written request therefor from any such holder, such
holder may thereafter look to Parent for payment of the 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 Parent.
 
  Board Representation. The Merger Agreement provides that promptly upon the
purchase pursuant to the Offer by Parent and any of its subsidiaries
(including Purchaser) of such number of Shares that represents at least a
majority of the Shares outstanding, and from time to time thereafter, Parent
will be entitled to designate such number of directors, rounded up to the next
whole number, on the Board that equals the product of (x) the number of
directors (the "Parent Designees") on the Board (giving effect to any increase
in the number of directors pursuant to the Merger Agreement), and (y) the
percentage that such number of Shares so purchased bears to the aggregate
number of Shares outstanding (such number being the "Board Percentage"), and
the Company will, subject to Parent's having theretofore provided the Company
with the information with respect to Parent's Designees required pursuant to
compliance with Section 14(f) of the Exchange Act, promptly satisfy the Board
Percentage by (i) increasing the size of the Board, or (ii) securing the
resignations of such number of directors as is necessary to enable Parent's
Designees to be elected to the Board (and the Company shall use its best
efforts to cause the then-remaining members of the Board to promptly so elect
Parent's Designees). At the request of Parent, the Company will take, at the
Company's expense, all lawful action necessary to effect any such election,
including, without limitation, mailing to the Stockholders the information
required by Section 14(f) of the Exchange Act and Rule 14f-1 promulgated
thereunder, unless such information has previously been provided to the
Company's Stockholders in the Schedule 14D-9. Following the election or
appointment of Parent's Designees pursuant to the Merger Agreement and prior
to the Effective Time, any amendment or termination of the Merger Agreement,
extension for the performance or waiver of the obligations or other acts of
Parent or Purchaser, or waiver of the Company's rights under the Merger
Agreement will require the concurrence of a majority of directors of the
Company then in office who are directors on the date of the Merger Agreement
and who voted to approve the Merger Agreement; provided that if there are no
such directors, such actions may be effected by majority vote of the entire
Board; and provided, further, that after the approval of the Merger Agreement
by the stockholders of the Company, no such amendment, termination,
modification or supplement shall reduce or change the Merger Consideration or
adversely affect the rights of the Company's stockholders under the Merger
Agreement without the approval of such stockholders.
 
  Consideration to be Paid in the Merger. The Merger Agreement provides that,
upon the terms and subject to the conditions set forth in the Merger
Agreement, and in accordance with the DGCL, Purchaser will be merged with and
into the Company at the Effective Time. At the Effective Time, the separate
corporate existence of Purchaser will cease, and the Company will continue as
the Surviving Corporation. At the Effective Time, by virtue of the Merger,
each Share issued and outstanding immediately prior to the Effective Time
(excluding Shares owned, directly or indirectly, by the Company or any wholly-
owned subsidiary of the Company or by
 
                                      21
<PAGE>
 
Parent, Purchaser or any other wholly-owned subsidiary of Parent and excluding
Dissenting Shares) will be converted into the right to receive the Merger
Consideration, without any interest thereon, upon surrender and exchange of a
certificate which immediately prior to the Effective Time represented such
Shares (each, a "Certificate"). Each share of the capital stock of Purchaser
issued and outstanding immediately prior to the Effective Time will be
converted into one fully paid and nonassessable share of common stock, par
value $.10 per share, of the Surviving Corporation, which will thereupon
become a direct, wholly-owned subsidiary of Parent. Each Share and all other
shares of capital stock of the Company that are owned by the Company and all
Shares and other shares of capital stock of the Company owned by Parent,
Purchaser or any other wholly-owned subsidiary of Parent or the Company will
be canceled and retired and will cease to exist and no consideration will be
delivered or deliverable in exchange therefor. The Merger will become
effective upon the filing of a Certificate of Merger with the Secretary of
State of the State of Delaware or at such time thereafter as is provided in
the Certificate of Merger.
 
  Options and Other Purchase Rights. After the Effective Time, each holder of
(i) a then-outstanding option (collectively, the "Employee Options") to
purchase Shares under the Company's 1992 Stock Option Plan and the Option
Agreements between the Company 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 the Company's Common Stock (collectively,
the "Other Options" and, together with the Employee Options, the "Options"),
will 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, 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,
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. The Company has represented and warranted to Parent and
Purchaser that the Stock Option Plan has been amended 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 the Company 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.
 
  Dissenting Shares. Shares that are outstanding immediately prior to the
Effective Time and which are held by Stockholders who shall have not voted in
favor of the Merger or consented thereto in writing and who shall have
demanded properly in writing appraisal for such shares in accordance with
Section 262 of the DGCL (collectively, the "Dissenting Shares") will not be
converted into or represent the right to receive the Merger Consideration.
Such Shares instead will, from and after the Effective Time, represent only
the right to receive payment of the appraised value of such Shares 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 under such Section 262 shall thereupon be deemed to have been converted
into and to have become exchangeable, as of the Effective Time, for the right
to receive, without any interest thereon, the Merger Consideration upon
surrender, in the manner provided in the Merger Agreement, of the Certificate
or Certificates that, immediately prior to the Effective Time, evidenced such
Shares.
 
  Stockholders' Meeting. The Merger Agreement provides that the Company will,
if required by applicable law in order to consummate the Merger, as soon as
practicable following the acceptance for payment of and payment for Shares by
Purchaser in the Offer, duly call, give notice of, convene and hold a
stockholders' meeting (the "Company Stockholders' Meeting") for the purpose of
approving the Merger Agreement and the transactions contemplated thereby. At
the Company Stockholders' Meeting, the Board will, subject to the
 
                                      22
<PAGE>
 
fiduciary duties of the Board of Directors, recommend to its stockholders the
adoption and approval of the Merger Agreement and the transactions
contemplated thereby. Parent has agreed that it will vote, or cause to be
voted, all of the Shares then owned by it, Purchaser or any of its other
subsidiaries in favor of approval of the Merger and the Merger Agreement.
Following the acceptance for payment of and payment for Shares by Purchaser in
the Offer, the Company and Parent will prepare and file with the Commission a
proxy statement, if necessary. The Company will use its reasonable best
efforts to respond to all Commission comments with respect to the proxy
statement and to cause the proxy statement and the form of proxy, which will
comply as to form with all applicable laws, to be mailed to the Stockholders.
 
  Notwithstanding the preceding paragraph, in the event that Parent, Purchaser
and any other subsidiary of Parent acquire at least 90% of the outstanding
Shares in the Offer, the parties to the Merger Agreement have agreed to take
all necessary and appropriate action to cause the Merger to become effective
as soon as practicable after acceptance for payment of Shares by Purchaser
pursuant to the Offer, without a meeting of stockholders of the Company, in
accordance with Section 253 of the DGCL.
 
  Representations and Warranties. The Merger Agreement contains various
representations and warranties of the parties. These include representations
and warranties by the Company to the Parent and Purchaser with respect to (i)
organization and authority, (ii) capitalization, (iii) authority relative to

frequently than monthly, to discuss the operations and business prospects of
the Company and its subsidiaries; (ii) the Company will promptly advise Parent
of the occurrence of any event having a Material Adverse Effect (as defined in
the Merger Agreement) on the Company and its subsidiaries, or any event that
would constitute a breach by the Company of any of its representations,
warranties, covenants or agreements set forth in the Merger Agreement; and
(iii) Parent will promptly advise the Company of the occurrence of any event
that would constitute a breach by Parent of any of its representations,
warranties, covenants or agreements set forth in the Merger Agreement.
 
  Other Agreements. The Company, Purchaser and Parent have agreed to use their
best efforts to comply promptly with all legal requirements which may be
imposed on such party with respect to the Offer, the Merger (including
furnishing all information required under the HSR Act and in connection with
approvals of or filings with any other governmental authority) to cooperate
with and furnish information to each other. Without limiting the generality or
effect of the foregoing, the Company will, and will cause its subsidiaries to,
take all reasonable actions necessary to obtain (and will cooperate with each
other in obtaining) any consent, authorization, order or approval of, or any
exemption by, any governmental authority or other public or private third
party, required to be obtained or made by the Company, Parent or any of their
subsidiaries in connection with the Offer, the Merger, the Merger Agreement,
or the taking of any action contemplated hereby or thereby.
 
  No Solicitation. The Merger Agreement provides that from and after the date
of the Merger Agreement and before the Effective Time, the Company shall not,
directly or indirectly, through any officer, director, employee, agent or
otherwise, (i) solicit, initiate or encourage submission of proposals, offers
or expressions of interest from any person relating to any acquisition or
purchase of all or (other than in the ordinary course of
 
                                      24
<PAGE>
 
business) a substantial portion of the assets of, or any equity interest in
(including by way of a tender offer), any company affiliated with the Company
or any business combination involving any company affiliated with the Company
(any of the foregoing proposals, offers or expressions of interest being
referred to herein as an "Acquisition Proposal") or (ii) participate in any
negotiations or discussions regarding, or furnish to any person any nonpublic
information with respect to, or otherwise cooperate in any way with, or assist
or participate in, facilitate or encourage, any Acquisition Proposal;
provided, however, that prior to the consummation of the Offer, the Company
may participate in negotiations or discussions with, and provide nonpublic
information to, any person concerning an Acquisition Proposal submitted in
writing by such person to the Board of Directors of the Company after the date
of the Merger Agreement if (A) such Acquisition Proposal was not solicited,
initiated or encouraged in violation of the Merger Agreement, and (B) the
Board of Directors of the Company, in its good faith judgment, believes that
such Acquisition Proposal is reasonably likely to result in a Superior
Proposal (as defined below).
 
  Until such time, if any, that Parent makes its first offer to the Company in
response to a notice that the Company's Board of Directors has determined that
an Acquisition Proposal constitutes a Superior Proposal, the Company is
required to notify Parent as promptly as practicable (and in any event within
48 hours) if any Acquisition Proposal is made and shall in such notice
indicate in reasonable detail the identity of the person making such
Acquisition Proposal and the terms and conditions of such Acquisition
Proposal, and shall keep Parent promptly advised of all material developments
relating to such Acquisition Proposal which could reasonably be expected to
culminate in the Board of Directors of the Company withdrawing, modifying or
amending its recommendation of the Offer, the Merger and the other
transactions contemplated in the Merger Agreement in a manner adverse to
Purchaser.
 
  If, as permitted above, the Company provides nonpublic information to any
person who makes an Acquisition Proposal, the Company shall require such
person to enter into a confidentiality agreement on terms substantially
similar to the Confidentiality Agreement, dated as of February 3, 1998,
besides Parent and the Company (the "Confidentiality Agreement"), as a
condition to and before providing any such information (except as to the
standstill provisions thereof, provided that if under the aforementioned
circumstances the Company enters into any confidentiality agreement without
standstill provisions substantially similar to those contained in the
Confidentiality Agreement, then Parent shall to the extent of the difference
be relieved of compliance with the Confidentiality Agreement's standstill
provisions).
 
  The Merger Agreement requires that the Company immediately cease and cause
to be terminated any then-existing discussions or negotiations with any
persons (other than Parent and Purchaser) conducted theretofore with respect
to any Acquisition Proposal. The Company may waive the provisions of any
"standstill" agreements between the Company and any party to the extent
necessary to permit such party to submit an Acquisition Proposal that the
Board of Directors of the Company believes, in its good faith judgment, is
reasonably likely to result in a Superior Proposal; provided, that such waiver
(i) does not violate or conflict with terms of the Merger Agreement, and (ii)
would not, in any event, permit such person to acquire any direct or indirect
beneficial ownership of Shares or participate in any tender offer or proxy
solicitation relating to the Company that would otherwise be prohibited by
such "standstill" agreement.
 
  Fees and Expenses. The Merger Agreement provides that, except as described
below, all costs and expenses incurred in connection with the Merger Agreement
and the transactions contemplated by the Merger Agreement will be paid by the
party incurring the expense.
 
  Conditions to the Merger. The respective obligation of each party to
consummate the Merger is subject to the satisfaction at or prior to the
Effective Time of the following conditions precedent: (a) the Merger Agreement
and the Merger shall have been approved and adopted by the affirmative vote of
the holders of a majority of Shares entitled to vote thereon if such vote is
required under the DGCL; (b) no order, decree or injunction shall have been
enacted, entered, promulgated or enforced by any United States court of
competent jurisdiction or any United States governmental authority which
prohibits the consummation of the Merger; provided, however, that the parties
hereto shall use their best efforts to have any such order, decree or
injunction vacated or reversed;
 
                                      25
<PAGE>
 
and (c) any waiting period applicable to the Merger under the HSR Act shall
have terminated or expired, all applicable requirements of the Exchange Act
shall have been satisfied and any applicable filings under state securities,
"Blue Sky" or takeover laws shall have been made.
 
  The obligations of the Company to consummate the Merger are subject to the
satisfaction or waiver at or prior to the Effective Time of the following
conditions precedent: (a) the representations and warranties of Parent and
Purchaser, when read without exception or qualification as to materiality or
Material Adverse Effect, shall be true and correct when made and at and as of
the consummation of the Offer with the same force and effect as if those
representations and warranties had been made at and as of such time (except to
the extent such representations and warranties speak as of a specified earlier
date, in which event such representations and warranties must be true and
correct as of such specified date), except where the failure to be so true and
correct would not, individually or in the aggregate, reasonably be expected to
have a Material Adverse Effect on Parent; and (b) Parent and Purchaser shall,
in all material respects, have performed all obligations and complied with all
covenants necessary to be performed or complied with by them on or before the
consummation of the Offer.
 
  The obligations of Parent and Purchaser to consummate the Merger are subject
to the satisfaction or waiver at or prior to the Effective Time of the
following conditions precedent: (a) the representations and warranties of the
Company, when read without exception or qualification as to materiality or
Material Adverse Effect on the Company, shall be true and correct when made
and at and as of the consummation of the Offer with the same force and effect
as if those representations and warranties had been made at and as of such
time (except to the extent such representations and warranties speak as of a
specified earlier date, in which event such representations and warranties
must be true and correct as of such specified date), except where the failure
to be so true and correct would not, individually or in the aggregate,
reasonably be expected to have a Material Adverse Effect on the Company; and
(b) the Company shall, in all material respects, have performed all
obligations and complied with all covenants necessary to be performed or
complied with by it on or before the consummation of the Offer.
 
  Termination. The Merger Agreement may be terminated and the Merger
contemplated thereby may be abandoned at any time notwithstanding approval
thereof by the respective shareholders of the Company and Purchaser, but prior
to the Effective Time: (a) by mutual written consent of the Company and
Parent; (b) by the Company or Parent, if either (i) the purchase of Shares
pursuant to the Offer has not been consummated on or before June 30, 1998, or
(ii) the Effective Time shall not have occurred on or before December 31, 1998
(provided that the right to terminate the Merger Agreement under the forgoing
clause (b) provision shall not be available to any party whose failure to
fulfill any obligation under the Merger Agreement has been the cause of or has
resulted in the failure of the consummation of the Offer or Effective Time to
occur on or before the applicable date set forth above); (c) by the Company if
there has been a material breach by Parent of any representation, warranty,
covenant or agreement set forth in the Merger Agreement, which breach has not
been cured within twenty (20) business days following notice to Parent of such
breach; (d) by Parent if (i) any of the events described in clauses (b) or (c)
of Section 14 hereof (Conditions to the Offer) has occurred, which event has
not been cured by the Company within twenty (20) business days following
notice to the Company of such event; or (ii) the Board of Directors of the
Company should fail to recommend to its stockholders approval of the
transactions contemplated by the Merger Agreement, including, without
limitation, the Offer and the Merger, or such recommendation shall have been
made and subsequently withdrawn, modified or amended in any manner adverse to
Parent; (e) by the Company if, prior to the Effective Time, a corporation,
partnership, person or other entity or group shall have made a bona fide
Acquisition Proposal that the Board of Directors of the Company believes, in
good faith after consultation with its financial advisors, is more favorable,
from a financial point of view, to the stockholders of the Company than the
proposal set forth in the Merger Agreement (a "Superior Proposal"); provided,
that (i) if a component of such Superior Proposal is cash consideration, then
the party making such Superior Proposal has cash on hand or financing in place
to provide such cash consideration, which financing is committed and/or
underwritten substantially to the same extent as Parent's financing was on the
date of the Merger Agreement, (ii) the Board of Directors of the Company
intends to enter into a definitive agreement relating to such Superior
Proposal immediately following the termination of the Merger Agreement
pursuant to
 
                                      26
<PAGE>
 
such provision, and (iii) Parent does not make, within two (2) business days
of receiving the first notice from the Company specifying that the Board of
Directors of the Company has determined that an Acquisition Proposal
constitutes a Superior Proposal giving rise to a potential right of
termination under this provision, an offer that the Board of Directors of the
Company believes, in good faith after consultation with its financial
advisors, is more favorable, from a financial point of view, to the Company's
stockholders than such Superior Proposal; or (f) by the Company or Parent, if
any court of competent jurisdiction in the United States or other United
States governmental authority shall have issued an order, decree or ruling or
taken any other action restraining, enjoining or otherwise prohibiting the
Merger and such order, decree, ruling or other action shall have become final
and nonappealable.
 
  Termination Fee. If the Merger Agreement is terminated (i) by Parent
pursuant to clause (b)(i) of the preceding paragraph, and the failure of the
consummation of the Offer has been caused by or is attributable to the failure
of those conditions to the Offer described in clauses (b), (c), (e) or (g)(2)
of Section 14 hereof (Conditions to the Offer) being satisfied, (ii) by Parent
pursuant to clause (d) of the preceding paragraph, or (iii) by the Company
pursuant to clause (e) of the preceding paragraph, and, in the case of any of
the foregoing, if the Company is not entitled to terminate the Merger
Agreement by reason of clause (c) of the preceding paragraph, then the Company
shall promptly (and in any event within two days of receipt by the Company of
written notice from Parent) pay to Parent (by wire transfer of immediately
available funds to an account designated by Parent): (A) a termination fee of
$6.0 million, plus (B) Parent's actual out-of-pocket expenses (including all
fees and expenses of its counsel, advisors, accountants and consultants)
incurred by Parent or on its behalf in connection with the transactions
contemplated in the Merger Agreement, not to exceed $500,000 in the aggregate.
 
  Indemnification and Insurance. From and after the consummation of the Offer
and for a period of six (6) years thereafter, Parent shall cause the Company
and its wholly-owned subsidiaries to maintain all rights of indemnification
(including rights to advancement of expenses and exculpation from liability)
existing in favor of the present and former directors, officers, employees and
agents of the Company and such subsidiaries (collectively, the "Indemnified
Parties") on terms no less favorable than those provided in the certificates
of incorporation and bylaws of such entities on the date of the Merger
Agreement with respect to matters occurring prior to the Effective Time. In
addition, Parent shall and shall cause each of the Company and its
subsidiaries (or any of their successors) to perform all of their respective
obligations under certain Indemnification Agreements entered into prior to the
date of the Merger Agreement. Further, Parent shall cause to be maintained in
effect for six (6) years from the consummation of the Offer the current
policies for directors' and officers' liability insurance maintained by the
Company for the benefit of the Indemnified Parties (provided that Parent may
substitute therefor policies of at least the same coverage containing terms
and conditions that are not materially less advantageous) with respect to
matters occurring prior to the Effective Time, to the extent such insurance is
available to Parent in the market. If such insurance is not available to
Parent in the market, Parent will provide such level of insurance as is then
provided to directors and officers of Parent. These obligations will continue
in the event that Parent or the Company or any of their respective successors
or assigns (i) consolidates with or merges into any other person and shall not
be the continuing or surviving corporation or entity in such consolidation or
merger, or (ii) transfers all or substantially all of its properties and
assets to any person.
 
  Shoppers Senior Notes. In the event that any of the 9 3/4% Senior Notes due
2004 (the "Senior Notes") issued by Shoppers pursuant to that certain
Indenture, dated as of June 6, 1997, between Shoppers, as issuer, SFW Holding
Corp., as guarantor, and Norwest Bank Minnesota, N.A., as trustee (the
"Indenture"), are tendered to Shoppers (the "Tendered Notes") by the holders
thereof as a result of the transactions contemplated in the Merger Agreement,
Parent will (i) cause Shoppers to comply with its obligations under the
Indenture, and (ii) if necessary, lend to Shoppers all amounts required to
repurchase any Tendered Notes on commercially reasonable terms and in
accordance with lending conditions then available in arms-length transactions.
 
  Amendment. The Merger Agreement may be amended by action taken by the
parties thereto at any time before or after approval of the Merger by the
stockholders of the Company but, after any such approval, no amendment shall
be made that would have any of the effects specified in DGCL Section 251(d)
without the
 
                                      27
<PAGE>
 
approval of the stockholders of the Company. This Merger Agreement may not be
amended except by an instrument in writing signed on behalf of each of the
parties thereto.
 
  Brokers or Finders Fees. No broker, finder or investment banker (other than
Wasserstein, whose fees shall be paid by the Company) is entitled to any
brokerage, finder's or other fee or commission in connection with the
transactions contemplated by the Merger Agreement based upon arrangements made
by or on behalf of the Company; and no broker, finder or investment banker
(other than DLJ, whose fees shall be paid by Parent) is entitled to any
brokerage, finder's or other fee or commission in connection with the
transactions contemplated by the Merger Agreement based upon arrangements made
by or on behalf of Parent or Purchaser.
 
  Timing. The exact timing and details for the Merger will depend upon legal
requirements and a variety of other factors, including the number of Shares
acquired by Purchaser pursuant to the Offer. Although Purchaser has agreed to
cause the Merger to be consummated on the terms and subject to the conditions
set forth above, there can be no assurance as to the timing of the Merger.
 
  Appraisal Rights. No appraisal rights are available to Stockholders in
connection with the Offer. However, if the Merger is consummated, a
Stockholder will have certain rights under Section 262 of the DGCL to dissent
and to demand appraisal of, and payment in cash for the fair value of, that
Stockholder's Shares. Those rights, if the statutory procedures are complied
with, could lead to a judicial determination of the fair value (excluding any
value arising from the Merger) required to be paid in cash to dissenting
Stockholders for their Shares. Any judicial determination of the fair value of
Shares could be based upon considerations other than or in addition to the
Offer Price and the market value of the Shares, including asset values and the
investment value of the Shares. The value so determined could be more or less
than the Offer Price or the Merger Consideration.
 
  If a Stockholder who demands appraisal under Section 262 of the DGCL fails
to perfect, or effectively withdraws or loses, his or her right to appraisal,
as provided in the DGCL, the Shares of that Stockholder will be converted into
rights to receive the Merger Consideration in accordance with the Merger
Agreement. A Stockholder may withdraw his or her demand for appraisal by
delivering to Purchaser a written withdrawal of such demand for appraisal and
acceptance of the Merger.
 
  Failure to follow the steps required by Section 262 of the DGCL for
perfecting appraisal rights may result in the loss of those rights.
 
  Going Private Transactions. Rule 13e-3 under the Exchange Act is applicable
to certain "going-private" transactions. Purchaser does not believe that Rule
13e-3 will be applicable to the Merger unless, among other things, the Merger
is completed more than one year after termination of the Offer. If applicable,
Rule 13e-3 would require, among other things, that certain financial
information regarding the Company and certain information regarding the
fairness of the Merger and the consideration offered to minority Stockholders
be filed with the Commission and disclosed to minority Stockholders prior to
consummation of the Merger.
 
  13. DIVIDENDS AND DISTRIBUTIONS
 
  If, on or after the date of the Merger Agreement, the Company should (i)
split, combine or otherwise change the Shares or its capitalization, (ii)
acquire currently outstanding Shares or otherwise cause a reduction in the
number of outstanding Shares or (iii) issue or sell additional Shares, shares
of any other class of capital stock, other voting securities or any securities
convertible into, or rights, warrants or options, conditional or otherwise, to
acquire, any of the foregoing, then, subject to the provisions of Section 14
below, Purchaser, in its sole discretion, may make such adjustments as it
deems appropriate in the Offer Price and other terms of the Offer, including,
without limitation, the number or type of securities offered to be purchased.
 
  If, on or after the date of the Merger Agreement, the Company declares or
pays any cash dividend on the Shares, makes other distributions on the Shares
or issues, with respect to the Shares, any additional Shares, shares of any
other class of capital stock, other voting securities or any securities
convertible into, or rights, warrants or
 
                                      28
<PAGE>
 
options, conditional or otherwise, to acquire, any of the foregoing, payable
or distributable to Stockholders of record prior to the transfer of the Shares
purchased pursuant to the Offer to Purchaser or its nominee or transferee on
the Company's stock transfer records, then, subject to Section 14 below, (i)
the Offer Price may, in the sole discretion of Purchaser, be reduced by the
amount of any cash dividend or cash distribution and (ii) the whole of any
non-cash dividend, distribution or issuance to be received by the tendering
Stockholders will (a) be received and held by the tendering Stockholders for
the account of Purchaser and will be required to be remitted promptly and
transferred by each tendering Stockholder to the Depositary for the account of
Purchaser, accompanied by appropriate documentation of transfer or (b) at the
direction of Purchaser, exercised for the benefit of Purchaser, in which case
the proceeds of exercise promptly will be remitted to Purchaser. Pending the
remittance and subject to applicable law, Purchaser will be entitled to all
rights and privileges as owner of any non-cash dividend, distribution,
issuance or proceeds and may withhold the entire Offer Price or deduct from
the Offer Price the amount or value of the non-cash dividend, distribution,
issuance or proceeds, as determined by Purchaser in its sole discretion.
 
  Pursuant to the terms of the Merger Agreement, the Company is prohibited
from taking any of the actions described in the two preceding paragraphs and
nothing in this Offer to Purchase shall constitute a waiver by Purchaser or
Parent of any of its rights under the Merger Agreement or a limitation of
remedies available to Purchaser or Parent for any breach of the Merger
Agreement, including termination of the Merger Agreement.
 
  14. CERTAIN CONDITIONS OF THE OFFER
 
  Notwithstanding any other provision of the Offer, Purchaser shall not be
required to accept for payment or, subject to any applicable rules and
regulations of the SEC, including Rule 14e-1(c) under the Exchange Act
(relating to Purchaser's obligation to pay for or return tendered Shares
promptly after expiration or termination of the Offer), to pay for any Shares
tendered unless the following conditions have been satisfied: (i) there have
been validly tendered and not withdrawn prior to the time the Offer shall
otherwise expire a number of Shares which constitutes a majority of the Shares
outstanding on a fully-diluted basis on the date of purchase ("on a fully-
diluted basis" for purposes hereof meaning, as of any date, the number of
Shares outstanding, together with Shares that the Company is or may be
required to issue pursuant to obligations outstanding at that date under
employee stock option or other benefit plans, options, warrants or convertible
or exchangeable securities, or otherwise) (the "Minimum Condition"); (ii) any
applicable waiting periods under the HSR Act shall have expired or been
terminated prior to the expiration of the Offer; and (iii) if, at any time on
or after the date of the Merger Agreement and before acceptance for payment
of, or payment for, such Shares any of the following events shall occur:
 
    (a) any Governmental Authority shall have enacted, issued, promulgated,
  enforced or entered any statute, rule, regulation, executive order, decree,
  injunction or other order which is in effect and which (1) materially
  restricts, prevents or prohibits consummation of the Offer or the Merger or
  results in the obligation to pay damages as a result of or in connection
  with the transactions contemplated by the Merger Agreement in amounts that
  would have a Material Adverse Effect on the Company, (2) prohibits or
  limits materially the ownership or operation by the Company, Parent or any
  of their subsidiaries of all or any material portion of the business or
  assets of the Company and its subsidiaries taken as a whole or compels the
  Company, Parent, or any of their subsidiaries to dispose of or hold
  separate all or any material portion of the business or assets of Parent or
  any of its subsidiaries, or of the Company and its subsidiaries taken as a
  whole, (3) imposes material limitations on the ability of Parent, Purchaser
  or any other subsidiary of Parent to acquire or hold, or to exercise
  effectively full rights of ownership of, any Shares, including, without
  limitation, the right to vote any Shares acquired by Purchaser pursuant to
  the Offer or otherwise on all matters properly presented to the Company's
  stockholders, including, without limitation, the approval and adoption of
  the Merger Agreement and the transactions contemplated thereby or (4)
  requires divestitures by Parent, Purchaser or any other affiliate of Parent
  of any Shares;
 
    (b) any of the representations and warranties of the Company set forth in
  the Merger Agreement, when read without any exception or qualification as
  to materiality or Material Adverse Effect on the Company, shall not be true
  and correct as if such representations and warranties were made at the time
  of such
 
                                      29
<PAGE>
 
  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 the Company, (ii) prevent the consummation of
  the Offer or (iii) have a material adverse effect on the benefits to Parent
  of the transactions contemplated by the Merger Agreement;
 
    (c) (i) the Company shall not have performed, in all material respects,
  all obligations and complied with all covenants necessary to be performed
  or complied with by it, or (ii) an event shall have occurred relating to a
  non-wholly owned subsidiary or partnership of the Company that would be
  prohibited by certain covenants set forth the Merger Agreement if such
  subsidiary or partnership had been wholly owned by the Company and which
  event has a material adverse effect on the benefits to Parent of the
  transactions contemplated by the Merger Agreement;
 
    (d) the Merger Agreement shall have been terminated in accordance with
  its terms;
 
    (e) the Board of Directors of the Company shall have (i) withdrawn or
  materially modified or changed (including by amendment of the Schedule 14D-
  9) in a manner adverse to the Purchaser its recommendation of the Offer,
  the Merger Agreement or the Merger, or (ii) the Board of Directors of the
  Company shall have approved or recommended an Acquisition Proposal;
 
    (f) other than the filing of the Certificate of Merger with respect to
  the Merger, all licenses, permits, authorizations, consents, orders,
  qualifications or approvals of, or declarations or filings with, or
  expirations of waiting periods imposed by, any governmental authority
  requisite to consummation of the Merger and the transactions contemplated
  thereby, shall have been filed, occurred or been obtained, as the case may
  be, except any of the foregoing the absence of which would not result in a
  Material Adverse Effect on the Company;
 
    (g) it shall have been publicly disclosed or Purchaser shall have
  otherwise learned that any person or "group" (as defined in Section
  13(d)(3) of the Exchange Act), other than Parent or its affiliates or any
  group of which any of them is a member, shall have (1) acquired beneficial
  ownership (determined pursuant to Rule 13d-3 promulgated under the Exchange
  Act) of more than 20% of any class or series of capital stock of the
  Company or shall have been granted an option, right or warrant, conditional
  or otherwise, to obtain more than 20% of any class or series of capital
  stock of the Company (including the Shares); or (2) without the prior
  consent of Parent, entered into any binding agreement or understanding with
  the Company with respect to (A) a merger, consolidation or other business
  combination with, or acquisition of a material portion of the assets of,
  the Company, or (B) a tender or exchange offer for Shares; or
 
    (h) there shall have occurred and be continuing (i) any general
  suspension of trading in securities on any national securities exchange or
  in the over-the-counter market, (ii) the declaration of a banking
  moratorium or any suspension of payments in respect of banks in the United
  States (whether or not mandatory), (iii) any indirect limitation (whether
  or not mandatory) by a United States governmental authority or agency on
  the extension of credit by banks or other financial institutions or (iv) a
  decline in the Dow Jones Industrial Average in excess of 25%, measured from
  the date of the Merger Agreement.
 
  The foregoing conditions are for the sole benefit of Purchaser and its
affiliates and, subject to the terms of the Merger Agreement, may be asserted
by the Purchaser regardless of the circumstances (including, without
limitation, any action or inaction by Purchaser or any of its affiliates)
giving rise to any such condition or may be waived by Purchaser, in whole or
in part, from time to time in its sole discretion, except as otherwise
provided in the Merger Agreement. The failure by Purchaser at any time to
exercise any of the foregoing rights shall not be deemed a waiver of any such
right and each such right shall be deemed an ongoing right and may be asserted
at any time and from time to time.
 
  15. CERTAIN LEGAL MATTERS
 
  Except as described in this Section 15, based on a review of publicly
available filings made by the Company with the Commission and other publicly
available information concerning the Company, but without any independent
investigation, neither Purchaser nor Parent is aware of any license or
regulatory permit that appears
 
                                      30
<PAGE>
 
to be material to the business of the Company and its subsidiaries, taken as a
whole, that might be adversely affected by Purchaser's acquisition of Shares
as contemplated in this Offer to Purchase or of any approval or other action
by any governmental authority that would be required for the acquisition or
ownership of Shares by Purchaser as contemplated in this Offer to Purchase.
Should any such approval or other action be required, Purchaser and Parent
presently contemplate that such approval or other action will be sought,
except as described below under "State Takeover Laws." There can be no
assurance that any such approval or other action, if needed, would be obtained
or would be obtained without substantial conditions, or that failure to obtain
any such approval or other action might not result in consequences adverse to
the Company's business, or that certain parts of the Company's business might
not have to be disposed of if such approvals were not obtained or other
actions were not taken or in order to obtain any such approval or other
action. If certain types of adverse action are taken with respect to the
matters discussed below, Purchaser could decline to accept for payment or pay
for any Shares tendered. See Section 14 above for certain conditions to the
Offer.
 
  State Takeover Laws. A number of states throughout the United States have
enacted takeover statutes that purport, in varying degrees, to be applicable
to attempts to acquire securities of corporations that are incorporated or
have assets, stockholders, executive offices or places of business in those
states. In Edgar v. MITE Corp., the Supreme Court of the United States held
that the Illinois Business Takeover Act, which involved state securities laws
that made the takeover of certain corporations more difficult, imposed a
substantial burden on interstate commerce and was therefore unconstitutional.
In CTS Corp. v. Dynamics Corp. of America, however, the Supreme Court of the
United States held that a state may, as a matter of corporate law and, in
particular, those laws concerning corporate governance, constitutionally
disqualify a potential acquiror from voting on the affairs of a target
corporation without prior approval of the remaining stockholders, provided
that the laws were applicable only under certain conditions.
 
  Section 203 of the DGCL limits the ability of a Delaware corporation to
engage in business combinations with "interested stockholders" (defined as any
beneficial owner of 15% or more of the outstanding voting stock of the
corporation) unless, among other things, the corporation's board of directors
has given its prior approval of either the business combination or the
transaction that resulted in the stockholder becoming an "interested
stockholder." The Company has represented in the Merger Agreement that it
approved the Merger Agreement and the transactions contemplated thereby,
including the Offer and the Merger, and has taken all necessary steps to
render Section 203 of the DGCL inapplicable to the Merger Agreement and the
transactions contemplated thereby, including the Offer and the Merger.
 
  Based on information supplied by the Company and the Company's
representations in the Merger Agreement, Purchaser does not believe that any
state takeover statutes apply to the Offer or the Merger. Neither Purchaser
nor Parent has currently complied with any state takeover statute or
regulation. Purchaser reserves the right to challenge the applicability or
validity of any state law purportedly applicable to the Offer or the Merger
and nothing in this Offer to Purchase or any action taken in connection with
the Offer or the Merger is intended to be a waiver of that right. If it is
asserted that any state takeover statute is applicable to the Offer or the
Merger and an appropriate court does not determine that it is inapplicable or
invalid as applied to the Offer or the Merger, Purchaser might be required to
file certain information with, or to receive approvals from, the relevant
state authorities, and Purchaser might be unable to accept for payment or pay
for Shares tendered pursuant to the Offer, or be delayed in consummating the
Offer or the Merger. In such case, Purchaser may not be obligated to accept
for payment or pay for any Shares tendered pursuant to the Offer.
 
  Antitrust. Under the provisions of the HSR Act applicable to the Offer, the
purchase of Shares under the Offer may be consummated following the expiration
of a 15-calendar day waiting period that follows the filing by Purchaser of a
Notification and Report Form with respect to the Offer, unless Purchaser
receives a request for additional information or documentary material from the
Antitrust Division of the Department of Justice (the "Antitrust Division") or
the Federal Trade Commission (the "FTC") or unless early termination of the
waiting period is granted. Purchaser expects that such filing will be made on
April 16, 1998, and that such waiting period will expire at 11:59 p.m. on May
1, 1998. If, within the initial 15-day waiting period, either the Antitrust
Division
 
                                      31
<PAGE>
 
or the FTC requests additional information or documentary material from
Purchaser concerning the Offer, the waiting period will be extended and would
expire at 11:59 P.M., New York City time, on the tenth calendar day after the
date of substantial compliance by Purchaser with such request. Only one
extension of the waiting period pursuant to a request for additional
information is authorized by the HSR Act. Thereafter, the waiting period may
be extended only by court order or with the consent of Purchaser. In practice,
complying with a request for additional information or documentary material
can take a significant amount of time. In addition, if the Antitrust Division
or the FTC raises substantive issues in connection with a proposed
transaction, the parties frequently engage in negotiations with the relevant
governmental agency concerning possible means of addressing those issues and
may agree to delay consummation of the transaction while the negotiations
continue. Moreover, subject to the terms of the Merger Agreement, (i)
Purchaser may extend the Offer for up to ten (10) business days after the
initial expiration date if fewer than 90% of the Shares outstanding as of such
date have been tendered at such date, and (ii) Purchaser shall extend the
Offer from time to time until June 30, 1998, if all conditions to the Offer
have not been satisfied or waived and the failure of a condition to be
satisfied is not due to the failure of the Company to fulfill any of its
obligations under the Merger Agreement.
 
  The FTC and the Antitrust Division frequently scrutinize the legality under
the antitrust laws of transactions such as Purchaser's proposed acquisition of
the Company. At any time before or after Purchaser's purchase of Shares
pursuant to the Offer, the Antitrust Division or the FTC could take such
action under the antitrust laws as it deems necessary or desirable in the
public interest, including seeking to enjoin the purchase of Shares pursuant
to the Offer or the consummation of the Merger or seeking the divestiture of
Shares acquired by Purchaser or the divestiture of substantial assets of
Purchaser or its subsidiaries, or of the Company or its subsidiaries. Private
parties may also bring legal action under the antitrust laws under certain
circumstances. There can be no assurance that a challenge to the Offer on
antitrust grounds will not be made or, if such a challenge is made, of the
result of that challenge.
 
  16. FEES AND EXPENSES
 
  Except as set forth below, neither Parent nor the Purchaser will pay any
fees or commissions to any broker, dealer or other person for soliciting
tenders of Shares pursuant to the Offer.
 
  Parent has engaged DLJ as the Dealer Manager in connection with the Offer
and as exclusive financial advisor to Parent in connection with the proposed
acquisition of the Company. Pursuant to the terms of DLJ's engagement, Parent
will pay DLJ $2,750,000 if Parent or any of its affiliates consummates a
merger, consolidation or any other business combination with the Company
(collectively, a "Transaction"). In the event that a Transaction is not
consummated and Parent receives a termination fee in connection therewith,
Parent shall pay to DLJ 20% of any such termination fee less fees previously
paid. Parent will also reimburse DLJ for travel and other out-of-pocket
expenses related to DLJ's engagement, whether or not the Offer or any other
Transaction is consummated, including reasonable legal fees and expenses, and
DLJ and certain related parties will be indemnified against certain
liabilities, including liabilities under the federal securities laws, arising
out of DLJ's engagement. DLJ has rendered various investment banking and other
advisory services to Parent and its affiliates in the past and is expected to
continue to render such services in the future, for which it has received and
will continue to receive customary compensation from Parent and its
affiliates. In the ordinary course of business, DLJ and its affiliates may
actively trade or hold Shares for their own account or for the account of
customers and, accordingly, may at any time hold a long or short position in
Shares.
 
  Purchaser has retained Corporate Investor Communications, Inc. to act as the
Information Agent, and First Union National Bank to act as the Depositary, in
connection with the Offer. The Information Agent and the Depositary each will
receive reasonable and customary compensation for their services, will be
reimbursed for certain reasonable out-of-pocket expenses and will be
indemnified against certain liabilities and expenses in connection therewith,
including certain liabilities under the federal securities laws.
 
  Brokers, dealers, commercial banks and trust companies will be reimbursed by
Purchaser for customary mailing and handling expenses incurred by them in
forwarding the offering materials to their customers.

  17. MISCELLANEOUS
 
  The Offer is not being made to (nor will tenders be accepted from or on
behalf of) holders of Shares who reside in any jurisdiction in which the
making of the Offer or the acceptance thereof would not be in compliance with
the securities, blue sky or other laws of the jurisdiction. However, Purchaser
may, in its discretion, take such action as it may deem necessary to make the
Offer in any jurisdiction and to extend the Offer to holders of Shares in that
jurisdiction. In any jurisdiction where the securities, blue sky or other laws
require the Offer to be made by a licensed broker or dealer, the Offer will be
deemed to be made on behalf of Purchaser by one or more registered brokers or
dealers that are licensed under the laws of the jurisdiction.
 
  Purchaser has filed the Schedule 14D-1 with the Commission containing
certain additional information with respect to the Offer pursuant to Rule 14d-
1 under the Exchange Act. The Schedule and any amendments to the Schedule,
including exhibits, may be examined and copies may be obtained from the
principal office of the Commission in the manner set forth in Section 8 above
(except that they will not be available at the regional offices of the
Commission).
 
  NO PERSON HAS BEEN AUTHORIZED TO GIVE ANY INFORMATION OR TO MAKE ANY
REPRESENTATION ON BEHALF OF THE PURCHASER THAT IS NOT CONTAINED IN THE OFFER
TO PURCHASE OR IN THE LETTER OF TRANSMITTAL AND, IF GIVEN OR MADE, THE
INFORMATION OR REPRESENTATION MUST NOT BE RELIED UPON AS HAVING BEEN
AUTHORIZED.

  Ladies and Gentlemen:
 
  The undersigned hereby tenders to DGC Acquisition, Inc., a Delaware
corporation ("Purchaser"), and a direct wholly-owned subsidiary of Richfood
Holdings, Inc., a Virginia corporation ("Parent"), the above-described shares
of common stock, $1.00 par value per share (the "Shares"), of Dart Group
Corporation, a Delaware corporation (the "Company"), for $160.00 per Share,
net to the seller in cash, upon the terms and subject to the conditions set
forth in the Offer to Purchase, dated April 15, 1998 (the "Offer to
Purchase"), receipt of which is hereby acknowledged, and in this Letter of
Transmittal (which, together with the Offer to Purchase and any amendments or
supplements hereto or thereto, collectively constitute the "Offer"). The
undersigned understands that Purchaser reserves the right to transfer or
assign, in whole or from time to time in part, to any newly formed direct or
indirect wholly-owned subsidiary of Purchaser, the right to purchase all or
any portion of the Shares tendered pursuant to the Offer, but any such
transfer or assignment will not relieve Purchaser of its obligations under the
Offer or prejudice the rights of tendering Stockholders to receive payment for
Shares validly tendered and accepted for payment pursuant to the Offer.
 
  Subject to, and effective upon, acceptance for payment of, or payment for,
Shares tendered with this Letter of Transmittal in accordance with the terms
and subject to the conditions of the Offer (including, if the Offer is
extended or amended, the terms or conditions of any such extension or
amendment), the undersigned hereby sells, assigns and transfers to, or upon
the order of, Purchaser, all right, title and interest in and to all of the
Shares that are being tendered hereby and any and all other Shares or other
securities issued or issuable in respect of such Shares on or after April 15,
1998 (a "Distribution") and irrevocably constitutes and appoints the
Depositary as the true and lawful agent and attorney-in-fact of the
undersigned with respect to such Shares (and any Distributions), with full
power of substitution (such power of attorney being deemed to be an
irrevocable power coupled with an interest), to (i) deliver Certificates
evidencing such Shares (and any Distributions), or transfer ownership of such
Shares (and all Distributions) on the account books maintained by a Book-Entry
Transfer Facility together, in any such case, with all accompanying evidences
of transfer and authenticity to, or upon the order of, Purchaser, upon receipt
by the Depositary as the undersigned's agent, of the purchase price with
respect to such Shares; (ii) present such Shares (and any Distributions) for
transfer on the books of the Company; and (iii) receive all benefits and
otherwise exercise all rights of beneficial ownership of such Shares (and any
Distributions), all in accordance with the terms and subject to the conditions
of the Offer.
 
  The undersigned hereby irrevocably appoints each designee of Purchaser as
the attorney-in-fact and proxy of the undersigned, each with full power of
substitution, to the full extent of the undersigned's rights with respect to
all Shares tendered hereby and accepted for payment and paid for by Purchaser
(and any Distributions) including, without limitation, the right to vote such
Shares (and any Distributions) in such manner as each such attorney and proxy
or his substitute shall, in his sole discretion, deem proper. All such powers
of attorney and proxies, being deemed to be irrevocable, shall be considered
coupled with an interest in the Shares tendered with this Letter of
Transmittal. Such appointment will be effective when, and only to the extent
that, Purchaser accepts such Shares for payment. Upon such acceptance for
payment, all prior powers of attorney and proxies given by the undersigned
with respect to such Shares (and any Distributions) will be revoked, without
further action, and no subsequent powers of attorneys and proxies may be given
with respect thereto (and, if given, will be deemed ineffective). The
designees of Purchaser will, with respect to the Shares (and any
Distributions) for which such appointment is effective, be empowered to
exercise all voting and other rights of the undersigned with respect to such
Shares (and any Distributions) as they in their sole discretion may deem
proper. Purchaser reserves the absolute right to require that, in order for
Shares to be deemed validly tendered, immediately upon the acceptance for
payment of such Shares, Purchaser or its designees are able to exercise full
voting rights with respect to such Shares (and any Distributions), including
voting at any meeting of Stockholders then scheduled.
 
  All authority conferred or agreed to be conferred by this Letter of
Transmittal shall be binding upon the successors, assigns, heirs, executors,
administrators and legal representatives of the undersigned and shall not be
affected by, and shall survive, the death or incapacity of the undersigned.
Except as stated in the Offer to Purchase, this tender is irrevocable.
 
  The undersigned hereby represents and warrants that the undersigned has full
power and authority to tender, sell, assign and transfer the Shares tendered
hereby (and any Distributions) and that, when the same are accepted for
payment and paid for by Purchaser, Purchaser will acquire good, marketable and
unencumbered title thereto, free and clear of all liens, restrictions, charges
and encumbrances, and that the Shares tendered hereby (and any Distributions)
will not be subject to any adverse claim. The undersigned, upon request, will
execute and deliver any additional documents deemed by the
 
                                       3
<PAGE>
 
Depositary or Purchaser to be necessary or desirable to complete the sale,
assignment and transfer of Shares tendered hereby (and any Distributions). In
addition, the undersigned shall promptly remit and transfer to the Depositary
for the account of Purchaser any and all Distributions issued to the
undersigned on or after April 15, 1998, in respect of the Shares tendered
hereby, accompanied by appropriate documentation of transfer, and pending such
remittance and transfer or appropriate assurance thereof, Purchaser shall be
entitled to all rights and privileges as owner of any such Distributions and
may withhold the entire purchase price or deduct from the purchase price the
amount of value thereof, as determined by Purchaser in its sole discretion.
 
  The undersigned understands that the valid tender of Shares pursuant to any
one of the procedures described in Section 3 of the Offer to Purchase and in
the instructions to this Letter of Transmittal will constitute a binding
agreement between the undersigned and Purchaser with respect to such Shares,
upon the terms and subject to the conditions of the Offer.
 
  The undersigned recognizes that, under certain circumstances set forth in
the Offer to Purchase, Purchaser may not be required to accept for payment any
of the Shares tendered hereby.
 
  Unless otherwise indicated in this Letter of Transmittal under "Special
Payment Instructions," please issue the check for the purchase price and
return any Certificates evidencing Shares not tendered or not accepted for
payment in the name(s) of the registered holder(s) appearing under
"Description of Shares Tendered." Similarly, unless otherwise indicated under
"Special Delivery Instructions," please mail the check for the purchase price
and return any Certificates evidencing Shares not tendered or not accepted for
payment (and accompanying documents, as appropriate) to the address(es) of the
registered holder(s) appearing under "Description of Shares Tendered." In the
event that both the "Special Payment Instructions" and the "Special Delivery
Instructions" are completed, please issue the check for the purchase price and
return any such Certificates evidencing Shares not tendered or not accepted
for payment (and accompanying documents, as appropriate) in the name(s) of,
and deliver such check and return such Certificates (and accompanying
documents, as appropriate) to, the person(s) so indicated. Unless otherwise
indicated in this Letter of Transmittal under "Special Payment Instructions,"
in the case of a book-entry delivery of Shares, please credit the account
maintained at the Book-Entry Facility indicated above with respect to any
Shares not accepted for payment. The undersigned recognizes that Purchaser has
no obligation pursuant to the "Special Payment Instructions" to transfer any
Shares from the name of the registered holder if Purchaser does not accept for
payment any of the Shares tendered hereby.

             FORMING PART OF THE TERMS AND CONDITIONS OF THE OFFER
 
  1. GUARANTEE OF SIGNATURES. Except as otherwise provided below, no signature
guarantee is required on this Letter of Transmittal if (i) this Letter of
Transmittal is signed by the registered holder(s) (which term, for the
purposes of this document, includes any participant in any of the Book-Entry
Transfer Facilities' systems whose name appears on a security position listing

holder has not completed either the box entitled "Special Delivery

with respect to all the tendered Shares, together with a Letter of Transmittal
(or a manually signed facsimile thereof), properly completed and duly
executed, with any required signature guarantees or an Agent's Message (as
defined in Section 2 of the Offer to Purchase) in connection with a book-entry
transfer and any other documents required by this Letter of Transmittal, must
be received by the Depositary within three New York Stock Exchange, Inc.
trading days after the date of such Notice of Guaranteed Delivery. If

of this Letter of Transmittal (or a facsimile thereof), waive any right to

inadequate, the information required under "Description of Shares Tendered"
should be listed on a separate signed schedule attached to this Letter of
Transmittal.

Certificates delivered to the Depositary with this Letter of Transmittal are

box entitled "Number of Shares Tendered." In such cases, a new Certificate for
the remainder of the Shares that were evidenced by your old Certificate(s)

Transmittal, unless otherwise provided in the box entitled "Special Payment
Instructions" or the box entitled "Special Delivery Instructions" on this
Letter of Transmittal, as soon as practicable after the Expiration Date. All

  If any of the Shares tendered hereby are owned of record by two or more
joint owners, all the owners must sign this Letter of Transmittal.
 
  If any of the tendered Shares are registered in different names on several
Certificates, it will be necessary to complete, sign and submit as many

  If this Letter of Transmittal or any Certificates or instruments of transfer
are signed by a trustee, executor, administrator, guardian, attorney-in-fact,
officer of a corporation or other person acting in a fiduciary or
representative capacity, that person should so indicate when signing, and
proper evidence satisfactory to Purchaser of that person's authority to so act
must be submitted.
 
  If this Letter of Transmittal is signed by the registered holder(s) of the
Shares listed and transmitted hereby, no endorsements of Certificates or
separate instruments of transfer are required unless payment is to be made, or
Certificates not tendered or not purchased are to be issued or returned, to a
person other than the registered holder(s). Signatures on the Certificates or
instruments of transfer must be guaranteed by an Eligible Institution.
 
  If this Letter of Transmittal is signed by a person other than the
registered holder(s) of the Shares evidenced by the Certificate(s) listed and
transmitted hereby, the Certificate(s) must be endorsed or accompanied by
appropriate instruments of transfer, in either case signed exactly as the
name(s) of the registered holder(s) appear on the Certificate(s). Signatures
on the Certificate(s) or instruments of transfer must be guaranteed by an
Eligible Institution.
 
  6. TRANSFER TAXES. Except as set forth in this Instruction 6, Purchaser will
pay or cause to be paid any transfer taxes with respect to the transfer and
sale of Shares to it or its order pursuant to the Offer. If, however, payment
of the purchase price is to be made to, or (in the circumstances permitted
hereby) if Certificates for Shares not tendered or not purchased are to be
registered in the name of, any person other than the registered holder(s), or
if tendered Certificates are registered in the name of any person other than
the person(s) signing this Letter of Transmittal, the amount of any transfer
taxes (whether imposed on the registered holder(s) or such person) payable on
account of the transfer to such person will be deducted from the purchase
price unless satisfactory evidence of the payment of such taxes or exemption
therefrom is submitted.
 
  Except as provided in this Instruction 6, it will not be necessary for
transfer tax stamps to be affixed to the Certificate(s) listed in this Letter
of Transmittal.
 
  7. SPECIAL PAYMENT AND DELIVERY INSTRUCTIONS. If a check and Certificates
for unpurchased Shares are to be issued in the name of a person other than the
signer of this Letter of Transmittal or if a check is to be sent and
Certificates are to be
 
                                       7
<PAGE>
 
returned to someone other than the signer of this Letter of Transmittal or to
an address other than that shown above, the appropriate boxes on this Letter
of Transmittal should be completed. If any tendered Shares are not purchased
for any reason and the Shares are delivered by Book-Entry Transfer Facility,
the Shares will be credited to an account maintained at the appropriate Book-
Entry Transfer Facility.

  9. WAIVER OF CONDITIONS. The conditions of the Offer may be waived by
Purchaser (subject to certain limitations in the Merger Agreement (as defined
in the Offer to Purchase)), in whole or in part, at any time or from time to
time, in Purchaser's sole discretion.
 
  10. BACKUP WITHHOLDING TAX. Each tendering Stockholder is required to
provide the Depositary with a correct Taxpayer Identification Number ("TIN")
on Substitute Form W-9, which is provided under "Important Tax Information"
below, and to certify that the Stockholder is not subject to backup
withholding. Failure to provide the information on the Substitute Form W-9 may
subject the tendering Stockholder to a penalty and 31% backup federal income
tax withholding on the payment of the purchase price for the Shares. If the
tendering Stockholder has not been issued a TIN and has applied for a TIN or
intends to apply for a TIN in the near future, the tendering Stockholder
should check the box in Part 3 of the Substitute Form W-9 and sign and date
both the Substitute Form W-9 and the "Certificate of Awaiting Taxpayer
Identification." If the Stockholder has indicated in the box in Part 3 that a
TIN has been applied for and the Depositary is not provided with a TIN by the
time of payment, the Depositary will withhold 31% of all payments of the
purchase price, if any, made thereafter pursuant to the Offer until a TIN is
provided to the Depositary.
 
  11. LOST OR DESTROYED CERTIFICATES. If any Certificate(s) representing
Shares has been lost, destroyed or stolen, the Stockholder should promptly
notify the Depositary by checking the box immediately preceding the Special
Payment/Special Delivery Instructions and indicating the number of Shares so
lost, destroyed or stolen. The Stockholders will then be instructed as to the
steps that must be taken in order to replace the Certificate(s). This Letter
of Transmittal and related documents cannot be processed until the procedures
for replacing lost, destroyed or stolen Certificates have been followed.
 
  IMPORTANT: THIS LETTER OF TRANSMITTAL OR A MANUALLY SIGNED FACSIMILE THEREOF
(TOGETHER WITH CERTIFICATES OR A BOOK-ENTRY CONFIRMATION FOR SHARES AND ANY
OTHER REQUIRED DOCUMENTS), OR A NOTICE OF GUARANTEED DELIVERY, MUST BE
RECEIVED BY THE DEPOSITARY ON OR PRIOR TO THE EXPIRATION DATE.
 
                           IMPORTANT TAX INFORMATION
 
  Under current federal income tax law, a Stockholder whose tendered Shares
are accepted for payment is required to provide the Depositary (as payer) with
such Stockholder's correct TIN on Substitute Form W-9 below. If such
Stockholder is an individual, the TIN is his Social Security Number. If the
tendering Stockholder has not been issued a TIN and has applied for a TIN, or
intends to apply for a TIN in the near future, the Stockholder should so
indicate on the Substitute Form W-9. See Instruction 10. If the Depositary is
not provided with the correct TIN, the Stockholder may be subject to a $50
penalty imposed by the Internal Revenue Service. In addition, payments that
are made to the Stockholder with respect to Shares purchased pursuant to the
Offer may be subject to backup federal income tax withholding at a 31% rate.
 
  Certain Stockholders (including, among others, all corporations and certain
foreign individuals) are not subject to these backup withholding and reporting
requirements and should indicate their status by writing "exempt" across the
face of, and by signing and dating, the Substitute Form W-9. In order for a
foreign individual to qualify as an exempt recipient, that Stockholder must
submit a statement, signed under penalties of perjury, attesting to that
individual's exempt status. Forms for such statements can be obtained from the
Depositary. See the enclosed Guidelines for Certificates of Taxpayer
Identification Number on Substitute Form W-9 for additional instructions.

<PAGE>
 
  If backup withholding applies, the Depositary is required to withhold 31% of
any payments made to the Stockholder. Backup withholding is not an additional
tax. Rather, the federal income tax liability of persons subject to backup
withholding will be reduced by the amount of tax withheld. If withholding
results in an overpayment of taxes, a refund may be obtained from the Internal
Revenue Service.
 
PURPOSE OF SUBSTITUTE FORM W-9
 
  To prevent backup federal income tax withholding with respect to payment of
the purchase price for Shares purchased pursuant to the Offer, a Stockholder
must provide the Depositary with his correct TIN by completing the Substitute
Form W-9 below, certifying that the TIN provided on the Substitute Form W-9 is
correct (or that the Stockholder is awaiting a TIN) and that (i) the
Stockholder has not been notified by the Internal Revenue Service that he is
subject to backup withholding as a result of failure to report all interest or
dividends, or (ii) the Internal Revenue Service has notified the Stockholder
that he is no longer subject to backup withholding.
 
WHAT NUMBER TO GIVE THE DEPOSITARY
 
  The Stockholder is required to give the Depositary the Social Security
Number or employer identification number of the record holder of the Shares
tendered hereby. If the Shares are registered in more than one name or are not
in the name of the actual owner, consult the enclosed Guidelines for
Certification of Taxpayer Identification Number on Substitute Form W-9 for
additional guidance on which number to report.

PRIVACY ACT NOTICE.--Section 6109 requires most recipients of dividend, inter-
est or other payments to give taxpayer identification numbers to payers who
must report the payments to the IRS. The IRS uses the numbers for identifica-
tion purposes. Payers must be given the numbers whether or not recipients are

withhold 31% of taxable interest, dividend and certain other payments to a
payee who does not furnish a taxpayer identification number to a payer. Cer-
tain penalties may also apply.
 
PENALTIES
(1) PENALTY FOR FAILURE TO FURNISH TAXPAYER IDENTIFICATION NUMBER.--If you
fail to furnish your taxpayer identification number to a payer, you are sub-
ject to a penalty of $50 for each such failure unless your failure is due to
reasonable cause and not to willful neglect.
(2) FAILURE TO REPORT CERTAIN DIVIDEND AND INTEREST PAYMENTS.--If you fail to
include any portion of an includible payment for interest, dividends, or pat-
ronage dividends in gross income, such failure will be treated as being due to
negligence and will be subject to a penalty of 5% on any portion of an
underpayment attributable to that failure, unless there is clear and convinc-
ing evidence to the contrary.
(3) CIVIL PENALTY FOR FALSE INFORMATION WITH RESPECT TO WITHHOLDING.--If you
make a false statement with no reasonable basis which results in no imposition
of backup withholding, you are subject to a penalty of $500.
(4) CRIMINAL PENALTY FOR FALSIFYING INFORMATION.--Falsifying certifications or
affirmations may subject you to criminal penalties including fines and/or im-
prisonment.

NUE SERVICE

                             Dart Group Corporation
                                       at
                             $160.00 Net Per Share

                              DGC Acquisition, Inc.
                       a direct wholly-owned subsidiary of
                             Richfood Holdings, Inc.

         DGC Acquisition, Inc., a Delaware corporation ("Purchaser") and a
direct wholly-owned subsidiary of Richfood Holdings, Inc., a Virginia
corporation ("Parent"), is offering to purchase all outstanding shares of common
stock, $1.00 par value per share (the "Shares"), of Dart Group Corporation, a
Delaware corporation (the "Company"), at a price of $160.00 per Share (the
"Offer Price"), net to the seller in cash, upon the terms and subject to the
conditions set forth in the Offer to Purchase, dated April 15, 1998, and in the
related Letter of Transmittal (which, together with any amendments or
supplements thereto, collectively constitute the "Offer"). Tendering
stockholders will not be obligated to pay brokerage fees or commissions or,
except as set forth in Instruction 6 of the Letter of Transmittal, transfer
taxes on the purchase of Shares pursuant to the Offer. The purpose of the Offer
is to acquire for cash as many outstanding Shares as possible as a first step in
acquiring the entire equity interest in the Company. Following consummation of
the Offer, Purchaser intends to effect the merger described below.

        THE OFFER AND WITHDRAWAL RIGHTS WILL EXPIRE AT 12:00 MIDNIGHT, 
  NEW YORK CITY TIME, ON TUESDAY, MAY 12, 1998, UNLESS THE OFFER IS EXTENDED.

         The Offer is conditioned upon, among other things, (1) a number of the
Shares representing a majority of all outstanding Shares on a fully diluted
basis being validly tendered and not withdrawn prior to the expiration of the
Offer, and (2) the expiration of certain waiting periods under the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended.

         The Offer is being made pursuant to an Agreement and Plan of Merger,
dated as of April 9, 1998 (the "Merger Agreement"), among Parent, Purchaser and
the Company. The Merger Agreement provides, among other things, for the
commencement of the Offer by Purchaser and further provides that after the
purchase of Shares pursuant to the Offer, subject to the satisfaction or waiver
of certain conditions, Purchaser will be merged with and into the Company (the
"Merger"), with the Company surviving the Merger as a direct wholly-owned
subsidiary of Parent. At the effective time of the Merger, each outstanding
Share (other than Shares owned by the Company or any wholly-owned subsidiary of
the Company or by Parent, Purchaser or any other wholly-owned subsidiary of
Parent, and Shares owned by stockholders who shall have properly exercised their
appraisal rights under Delaware law) will be converted into the right to receive
$160.00 in cash or any greater amount paid pursuant to the Offer, without
interest.

         The Board of Directors of the Company (the "Board") has unanimously
determined that the Offer and the Merger are fair to, and in the best interests
of, the Company and its stockholders, has approved the Merger Agreement and the
transactions contemplated by the Merger Agreement, including the Offer and the
Merger,
<PAGE>
 
and recommends that the Company's stockholders accept the Offer and tender all
of their Shares pursuant thereto.

         For purposes of the Offer, Purchaser will be deemed to have accepted
for payment (and thereby purchased) tendered Shares as, if and when Purchaser
gives oral or written notice to First Union National Bank (the "Depositary") of
its acceptance of such Shares for payment pursuant to the Offer. Upon the terms
and subject to the conditions of the Offer, payment for Shares purchased
pursuant to the Offer will be made by deposit of the purchase price therefor
with the Depositary, which will act as agent for tendering stockholders for the
purposes of receiving payment from Purchaser and transmitting payment to
tendering stockholders whose Shares have theretofore been accepted for payment.
In all cases, payment for Shares purchased pursuant to the Offer will be made
only after timely receipt by the Depositary of (i) certificates for (or a timely
Book-Entry Confirmation (as defined in Section 3 of the Offer to Purchase) with
respect to) such Shares, (ii) the Letter of Transmittal (or a manually signed
facsimile thereof), properly completed and duly executed with all required
signature guarantees or an agent's message, and (iii) all other documents
required by the Letter of Transmittal. Under no circumstances will interest be
paid on the purchase price for Shares to be paid by Purchaser, regardless of any
delay in making such payment.

         The term "Expiration Date" shall mean 12:00 midnight, New York City
time, on Tuesday, May 12, 1998, unless and until Purchaser, in accordance with
the terms of the Offer and the Merger Agreement, shall have extended the period
of time during which the Offer is open, in which event the term "Expiration
Date" shall mean the latest time and date at which the Offer, as so extended by
Purchaser, shall expire. Subject to the terms of the Merger Agreement and
applicable law, Purchaser expressly reserves the right, at any time or from time
to time, to extend the period of time during which the Offer is open and, in
certain circumstances, may be required to extend the Offer until June 30, 1998,
and thereby delay acceptance for payment of, or payment for, any Shares by
giving oral or written notice of such extension to the Depositary and by making
a public announcement of such extension. Purchaser shall not have any obligation
to pay interest on the purchase price for tendered Shares whether or not
Purchaser exercises its right to extend the period of time during which the
Offer is open. Any such extension will be followed by a public announcement
thereof no later than 9:00 a.m., New York City time, on the next business day
after the previously scheduled Expiration Date. During any such extension, all
Shares previously tendered and not withdrawn will remain subject to the Offer,
subject to the right of a tendering stockholder to withdraw such stockholder's
Shares. Without limiting the manner in which Purchaser may choose to make any
public announcement, Purchaser will have no obligation to publish, advertise or
otherwise communicate any such announcement other than by issuing a release to
the Dow Jones News Service or as otherwise may be required by law.

         Except as otherwise provided in the Offer to Purchase, tenders of
Shares are irrevocable. Shares tendered pursuant to the Offer may be withdrawn
at any time prior to the Expiration Date and, unless theretofore accepted for
payment by Purchaser as provided for in the Offer to Purchase, may also be
withdrawn at any time after Saturday, June 13, 1998. For a withdrawal to be
effective, a written, telegraphic or facsimile transmission notice of withdrawal
must be timely received by the Depositary at its address set forth on the back
cover of the Offer to Purchase. Any such notice of withdrawal must specify the
name of the person who tendered the Shares to be withdrawn, the number of Shares
to be withdrawn and the name of the registered holder, if different from that of
the person who tendered such Shares. If certificates evidencing Shares have been
delivered or otherwise identified to the Depositary, then, prior to the release
of such certificates, the tendering stockholder must also submit the serial
numbers shown on the particular certificates evidencing the Shares to be
withdrawn, and the signature on the notice of withdrawal must be guaranteed by
an Eligible Institution, as defined in Section 3 of the Offer to Purchase
(except in the case of Shares tendered for the account of an Eligible
Institution). If Shares have been tendered pursuant to the procedure for
book-entry transfer set forth in Section 3 of the Offer to Purchase, the notice
of withdrawal must specify the name and number of the account at the applicable
Book-Entry Transfer Facility (as defined in Section 3 of the Offer to Purchase)
to be credited with the withdrawn Shares. All questions as to the form and
validity (including time of receipt) of notices of withdrawal will be determined
by Purchaser, in its sole discretion, whose determination shall be final and
binding on all parties. Any Shares properly withdrawn will be deemed not validly
tendered for purposes of the Offer, but may be tendered at any subsequent time
prior to the Expiration Date by following any of the procedures described in
Section 3 of the Offer to Purchase.

         The Company has provided Purchaser with the Company's stockholder list
and security position listings for the purpose of disseminating the Offer to
holders of Shares. The Offer to Purchase, the related Letter of Transmittal and,
if required, any other relevant materials will be mailed to record holders of
Shares and will be furnished to brokers, dealers, commercial banks, trust
companies and similar persons whose names, or the name of whose nominees, appear
on the Company's stockholders list or, if applicable, who are listed as
participants in a clearing agency's security position listing, for subsequent
transmittal to beneficial owners of Shares by Purchaser.

         The information required to be disclosed by paragraph (e)(1)(vii) of
Rule 14d-6 of the General Rules and Regulations under the Securities Exchange
Act of 1934, as amended, is contained in the Offer to Purchase and is
incorporated herein by reference.

         The Offer to Purchase and the related Letter of Transmittal contain
important information which should be read carefully before any decision is made
with respect to the Offer.

and other tender offer documents may be directed to the Information Agent as set
forth below, and copies will be furnished promptly at Purchaser's expense.
Questions or requests for assistance may be directed to the Information Agent or

[LETTERHEAD OF RICHFOOD HOLDINGS, INC. APPEARS HERE]

FOR IMMEDIATE RELEASE 

                   RICHFOOD HOLDINGS, INC. AGREES TO ACQUIRE
                       DART GROUP CORPORATION, OWNER OF
                            SHOPPERS FOOD WAREHOUSE

Richmond, Virginia, April 9, 1998 - Richfood Holdings, Inc. (NYSE: RFH) 
announced today the signing of a definitive merger agreement pursuant to which 
Richfood will acquire all of the outstanding common stock of Dart Group 
Corporation for $160 per share in cash, or approximately $207 million.  Dart's 
Board of Directors has unanimously approved the agreement and recommended that 
Dart's shareholders accept the Richfood offer.

To implement the agreement, Richfood will commence a cash tender offer within 
five business days.  The completion of the tender offer is not subject to 
financing, which has been committed by First Union National Bank, but is subject
to other customary conditions, including the acquisition of a majority of Dart's
outstanding common stock on a fully diluted basis and the expiration of the 
waiting period under the Hart-Scott-Rodino Act.  Shares not purchased under the 
tender offer will be acquired in a subsequent merger, at the same price, as soon
as practicable after completion of the tender offer.  Following the transaction,
Dart will become a wholly-owned subsidiary of Richfood.

Dart Group, headquartered in Landover, Maryland, comprises Shoppers Food 
Warehouse, a 100% owned chain of 37 price-impact supermarkets operating in the 
Greater Washington, D.C. market; Trak Auto, a publicly owned retailer of auto 
parts, 67% owned by Dart; Crown Books, a publicly owned retailer of popular 
books, 52% owned by Dart; and Total Beverage, a 100% owned discount beverage 
retailer based in Washington, D.C.

"The acquisition of Shoppers Food Warehouse fits perfectly into Richfood's 
strategy of selectively expanding its retail presence in the Mid-Atlantic 
market," said John Stokely, President and Chief Executive Officer of Richfood.  
"Shoppers is located squarely in the middle of our core market," Stokely added, 
"flanked by our Metro stores to the north in Baltimore and Farm Fresh to the 
south in Tidewater, with virtually no overlap between its locations and those of
Richfood's other customers.  We believe that combining Shoppers' highly 
productive retail format with the full range of Richfood's distribution and 
logistic capabilities will create significant economics benefiting customers and
shareholders alike. With this acquisition, Richfood will own approximately 100
supermarkets stretching from Delaware to southern Virginia, achieving a critical
mass that will permit us to optimize operating leverage, particularly in the
areas of distribution, technology and shared administrative services. As with
our recent Farm Fresh acquisition, the acquisition of Shoppers will be
immediately accretive to Richfood."

Dear Stockholder:
 
  We are pleased to report that Dart Group Corporation (the "Company") has
entered into a merger agreement with Richfood Holdings, Inc. ("Richfood") and
one of its subsidiaries that provides for the acquisition of the Company by
Richfood at a price of $160.00 per share in cash. Under the terms of the
proposed transaction, a Richfood subsidiary is today commencing a cash tender
offer for all outstanding shares of the Company's common stock at $160.00 per
share. Following the successful completion of the tender offer, the Richfood
subsidiary will be merged into the Company and all shares not purchased by the
Richfood subsidiary in the tender offer will be converted into the right to
receive $160.00 per share in cash in the merger.
 
  YOUR BOARD OF DIRECTORS HAS UNANIMOUSLY APPROVED THE RICHFOOD TENDER OFFER
AND DETERMINED THAT THE TERMS OF THE TENDER OFFER AND THE MERGER, TAKEN
TOGETHER, ARE FAIR TO, AND IN THE BEST INTERESTS OF, THE COMPANY AND ITS
STOCKHOLDERS. ACCORDINGLY, THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS
ACCEPTANCE OF THE RICHFOOD TENDER OFFER AND APPROVAL AND ADOPTION OF THE
MERGER AGREEMENT BY THE STOCKHOLDERS OF THE COMPANY.
 
  In arriving at its recommendations, the Board of Directors gave careful
consideration to a number of factors. These factors included the opinion dated
April 8, 1998, of Wasserstein Perella & Co., Inc. ("Wasserstein Perella"),
financial advisor to the Company, to the effect that, as of such date and
based upon and subject to certain matters stated in such opinion, the cash
consideration of $160.00 per share to be received by Company stockholders
(other than Richfood and its affiliates) in the offer and the merger was fair
from a financial point of view to such stockholders.
 
  Accompanying this letter is a copy of the Company's
Solicitation/Recommendation Statement on Schedule 14D-9. Also enclosed is
Richfood's Offer to Purchase and related materials, including a Letter of
Transmittal for use in tendering shares. We urge you to read carefully the
enclosed materials, including Wasserstein Perella's opinion, which is attached
to the Schedule 14D-9.
 
  The management and directors of Dart Group Corporation thank you for the
support you have given the Company.
 
                                       Sincerely,
 
                                       /s/ Richard B. Stone

Attention:  Mr. John C. Belknap
            Executive Vice President and
            Chief Financial Officer

                     Re:  Commitment for Credit Facilities
                          --------------------------------
                                        
Gentlemen:

     Richfood Holdings, Inc. (the "Company") has advised First Union National
Bank ("First Union") that the Company intends to make a tender offer to acquire
Dart Group Corporation ("Dart") by merger or stock acquisition (the "Dart
Acquisition") pursuant to merger or stock acquisition documents (the
"Acquisition Documents") to be negotiated and entered into between the Company
and Dart.  Based on First Union's present understanding of the proposed
transaction, First Union anticipates that the Company would enter into a Credit
Agreement with certain financial institutions (the "Bank Credit Facility"),
having substantially the terms set forth on the summary of terms and conditions
attached hereto (the "Term Sheet"), providing for credit facilities in an
aggregate amount of $450 million, $250 million of which would be a revolving
credit facility and $200 million of which would be a term loan facility.

     First Union understands that the borrowings under the Bank Credit Facility
will provide funds sufficient to enable the Company to consummate the Dart
Acquisition, to refinance certain existing indebtedness of the Company and of
Dart, to finance capital expenditures and other permitted acquisitions, to pay
related fees and expenses and to provide for working capital and other general
corporate purposes.

     Based upon and subject to the foregoing and to the terms and conditions set
forth below and in the Term Sheet, First Union is pleased to confirm its
commitment (this "Commitment") to provide the Bank Credit Facility to the
Company.  First Union's obligation to provide the Bank Credit Facility pursuant
to this Commitment is subject to (i) the Company's written acceptance of the
letter from First Union and First Union Capital Markets, a division of Wheat
First Securities, Inc. ("Capital Markets" or the "Arranger") to the Company of
even date herewith (the 
<PAGE>
 
Richfood Holdings, Inc.

"Fee Letter"), pursuant to which the Company agrees to pay First Union and
Capital Markets certain fees in connection with the Bank Credit Facility as more
particularly set forth therein, (ii) the completion of a definitive credit
agreement and related documentation for the Bank Credit Facility, customary for
transactions of this type, in form and substance satisfactory to First Union,
(iii) completion of all documentation relating to the Dart Acquisition including
the Acquisition Documents in form and substance reasonably satisfactory to First
Union; (iv) compliance with all applicable laws and regulations (including
compliance of this Commitment and the transactions described herein with
Regulation U of the Federal Reserve Board and all other applicable federal
banking laws, rules and regulations), and (v) the satisfaction of all other
conditions described herein, in the Term Sheet and in such definitive
documentation. Further, this Commitment is subject to there not having occurred
any material adverse disruption or other change in the financial, banking or
capital markets that has had or could have a materially adverse effect, in First
Union's sole opinion, on the syndication of the Bank Credit Facility.

     It is agreed that First Union will act as the sole administrative agent
(the "Administrative Agent") for any other Lenders under the Bank Credit
Facility.  First Union, through Capital Markets, will also serve as sole
arranger and manager of the syndication effort to form a syndicate of financial
institutions (collectively with First Union, the "Lenders") reasonably
satisfactory to the Company and Capital Markets and to exercise its reasonable
good faith efforts to syndicate all or a portion of the Bank Credit Facility.
In connection with such syndication effort, First Union will manage all aspects
of the syndication, including without limitation making decisions as to the
selection and number of institutions to be approached and when such institutions
will be approached, the award of titles (if any), when commitments will be
accepted, which institutions will participate, the allocations of commitments
among syndicate Lenders and the amount and distribution of fees payable to
syndicate Lenders.  As part of this process, First Union will consult with the
Company regarding the selection and number of institutions to be approached.

     First Union reserves the right, prior to or after the execution of
definitive documentation with respect to the Bank Credit Facility, and as part
of any syndication thereof or otherwise, to arrange for the assignment of a
portion of this Commitment, in accordance with the Term Sheet, to one or more
mutually acceptable financial institutions that will become Lenders and party to
such definitive documentation.  In addition, in connection with any such
syndication, the Company acknowledges that First Union may allocate a portion of
the fees payable under the Fee Letter to such other Lenders.  It is agreed,

                          Agreement) upon the terms and subject to the
                          conditions to be set out in the Credit Agreement,

                          prepayment to occur during a LIBOR interest period).

Interest Rate Options:    Principal advances under the Revolving Credit Facility
                          and the outstanding principal balance of the Term Loan
                          Facility will bear interest, at the option of the
                          Company, at either (i) the Base Rate plus the
                          Applicable Margin, or (ii) Adjusted one, two, three or
                          six-month LIBOR plus the Applicable Margin. The

                          option under the Revolving Credit Facility upon the
                          terms and conditions to be specified in the Credit
                          Agreement.

                          The Base Rate means the higher of (i) First Union's
                          Prime Rate, or (ii) the Federal Funds Rate plus 0.50%.
                          Adjusted LIBOR means the London Interbank Offered
                          Rate, as reported by Telerate, adjusted for applicable
                          reserves, if any.

                          Swing line loans will bear interest at the Base Rate
                          as it exists from time to time, minus 1-1/2% per
                          annum, with such rate to change as of the date of each
                          change in such Base Rate.

                          Interest rates will be selected and set, and accrued
                          interest will be due and payable, as provided in the
                          Credit Agreement.

Interest Rate Margins:    The Applicable Margin for Loans when bearing interest
                          based upon the Base Rate will be 0%. The Applicable
                          Margin for Loans when bearing interest based upon
                          Adjusted LIBOR will vary based on the ratio of the
                          Company's Total Funded Debt to EBITDA Ratio (as
                          defined below) in effect from time to time during the
                          term of the Revolving Credit Facility and the Term
                          Loan Facility (see Appendix A attached hereto for

                    letter of credit subfacility under the Revolving Credit

                    account of the Lenders an annual letter of credit fee equal
                    to the daily average Applicable Margin for Libor Loans under
                    the Revolving Credit Facility (or 30% of such Applicable
                    Margin in the case of trade letters of credit), as it exists
                    during the applicable period, multiplied by the daily
                    average face amount of the letter of credit during the
                    applicable period, and (2) to the Agent for its own account
                    an annual facing fee equal to 1/8th of 1% of the face amount
                    of the letter of credit.  The letter of credit fees will be
                    payable quarterly in arrears.

(subject to the fiduciary duties of the Board of Directors as advised by
counsel) such recommendation of the Board of Directors of Dart in favor of the
Offer and Merger and otherwise complying with Rule 14d-9 under the Exchange Act.
Dart covenants that the Schedule 14D-9 shall comply in all material respects
with the Exchange Act and any other applicable Law and shall contain (or shall
be amended in a timely manner to contain) all information which is required to
be included therein in accordance with the Exchange Act and the rules and
regulations thereunder and any other applicable Law.  Dart, Richfood and Merger
Subsidiary each agree promptly to correct any information provided by them for

material respect and Dart further agrees to take all lawful action necessary to
cause the Schedule 14D-9 as so corrected to be filed promptly with the SEC and
disseminated to the holders of Dart Common Stock, in each case as and to the
extent required by applicable Law.  Richfood, Merger Subsidiary and their
counsel shall be given an opportunity to review and comment upon the Schedule
14D-9 and any amendments thereto prior to the filing thereof with the SEC.  In
addition, Dart agrees to provide Richfood, Merger Subsidiary and their counsel
in writing with any comments or other communications that Dart or its counsel
may receive from time to time from the SEC or its staff with respect to the
Schedule 14D-9 promptly after the receipt of such comments or other
communications.  In connection with the Offer, Dart shall (or shall cause its
transfer agent to) promptly furnish Richfood with mailing labels, security
position listings and all available listings or computer files containing the
names and addresses of the record holders of Dart Common Stock as of the latest
practicable date and shall furnish Richfood with such information and assistance
(including updated lists of stockholders, mailing labels and lists of security
positions) as Richfood or its agents may reasonably request in communicating the
Offer to the record and beneficial holders of Dart Common Stock.  Subject to the
requirements of applicable Law, and except for such actions as are necessary to
disseminate the Offer Documents and any other documents necessary to consummate
the

Richfood's Designees to be elected to the Board of Directors of Dart (and Dart
shall use its best efforts to cause the then-remaining members of the Dart's
Board of Directors to promptly so elect Richfood's Designees).  At the request
of Richfood, Dart shall take, at Dart's expense, all lawful action necessary to
effect any such election, including, without limitation, mailing to Dart's
stockholders the information required by Section 14(f) of the Exchange Act and
Rule 14f-1 promulgated thereunder, unless such information has previously been

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,

form for transfer and that the Person requesting such payment shall pay any

may have had in respect of such Option.

furnish to any person any nonpublic information with respect to, or otherwise
cooperate in any way with, or assist or participate in, facilitate or encourage,

     (b) Until such time, if any, that Richfood makes its first offer after

Proposal, Dart shall notify Richfood as promptly as practicable (and in any

notice indicate in reasonable detail the identity of the person making such
Acquisition Proposal and the terms and conditions of such Acquisition Proposal,

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

proxy solicitation relating to Dart that would otherwise be prohibited by such
"standstill" agreement.

representations and warranties had been made at and as of such time (except to
the extent such representations and warranties speak as of a specified earlier
date, in which event such representations and warranties must be true and
correct as of such specified date), except where the failure to be so true and
correct would not, individually or in the aggregate, reasonably be expected to
have a Material Adverse Effect on Dart; and

     (b) Dart shall, in all material respects, have performed all obligations
and complied with all covenants necessary to be performed or complied with by it
on or before the consummation of the Offer.

     order, decree, injunction or other order which is in effect and which (1)
     materially restricts, prevents or prohibits consummation of the Offer or
     the Merger or results in the obligation to pay damages as a result of or in
     connection with the transactions contemplated by this Agreement in amounts
     that would have a Material Adverse Effect on Dart, (2) prohibits or limits

     Subsidiaries of all or any material portion of the business or assets of
     Dart and its Subsidiaries taken as a whole or compels Dart, Richfood, or

     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
