Rite Aid Corporation

MARTIN L. GRASS
Chairman
Chief Executive Officer 
   
                                                               February 16, 1996
    
 
Dear Stockholder:
 
   
     You are cordially invited to attend the Special Meeting of Stockholders of
Rite Aid Corporation ('Rite Aid') to be held at the Radisson Hotel, 1150 Camp
Hill Bypass, Camp Hill, Pennsylvania on Thursday, March 28, 1996, at 10:00 a.m.,
local time (the 'Rite Aid Special Meeting').
    
 
   
     The purpose of the Rite Aid Special Meeting is to consider a proposal to
approve the issuance of up to a maximum of 42,865,712 shares (the 'Share
Issuance') of Rite Aid common stock, par value $1.00 ('Rite Aid Common Stock'),
pursuant to an Agreement and Plan of Merger, dated as of November 29, 1995 (the
'Merger Agreement'), by and among Rite Aid, Ocean Acquisition Corporation
('Sub'), a wholly owned subsidiary of Rite Aid, and Revco D.S., Inc. ('Revco'),
which provides for the merger (the 'Merger') of Sub with and into Revco. As the
first step of the transaction contemplated by the Merger Agreement, Sub has
commenced a tender offer (the 'Offer') to purchase 50.1% of the outstanding
shares of common stock, par value $.01, of Revco ('Revco Common Stock') at a
price of $27.50 per share of Revco Common Stock, on a fully diluted basis. The
Offer is currently scheduled to expire on February 23, 1996.
    
 
     In the Merger, each share of Revco Common Stock, other than shares of Revco
Common Stock owned by Revco as treasury stock and any shares of Revco Common
Stock owned by Rite Aid, Sub or any other direct or indirect wholly owned
subsidiary of Rite Aid (and, if the Alternative Consideration, as defined below,
is applicable, other than shares of Revco Common Stock held by holders who have
properly exercised and perfected their appraisal rights under the Delaware
General Corporation Law), will by virtue of the Merger and without any action on
the part of the holder thereof be converted into either (i) the right to receive
a number of duly authorized, validly issued, fully paid and nonassessable shares
of Rite Aid Common Stock determined as set forth below (the 'Exchange Ratio');
provided that Rite Aid will not issue more than 1.125 or fewer than .91666
shares of Rite Aid Common Stock per share of Revco Common Stock or (ii) if the
Alternative Consideration is applicable, the right to receive the Alternative
Consideration.
 
     As described in the Proxy Statement accompanying this letter, the value of
Rite Aid Common Stock to be delivered for each share of Revco Common Stock in
the Merger will increase to the extent the average value of Rite Aid Common

Stock during a pricing period is greater than $27.50 per share and will decrease
if the average value of Rite Aid Common Stock during such pricing period is less
than $27.50 per share, but in no event will more than 1.125 shares or fewer than
 .91666 shares of Rite Aid Common Stock be issued for each share of Revco Common
Stock in the Merger.
 
     In the event that at the Rite Aid Special Meeting the stockholders of Rite
Aid do not approve the Share Issuance pursuant to the Merger, and if all
conditions to the Merger are otherwise satisfied or waived (if permissible),
Rite Aid will nonetheless cause the Merger to occur, issue a number of shares of
Rite Aid Common Stock equal to 19.9% of the then outstanding shares of Rite Aid
Common Stock, and shares of Revco Common Stock issued immediately prior to the
effective time of the Merger (other than shares of Revco Common Stock held in
treasury and shares of Revco Common Stock owned by Rite Aid and its subsidiaries
and other than shares of Revco Common Stock held by holders who have properly
exercised and perfected their appraisal rights under the Delaware General
Corporation Law) will, at the effective time of the Merger, be converted into
the right to receive a combination of (x) shares of Rite Aid Common Stock which
will represent in the aggregate 19.9% of the then outstanding shares of Rite Aid
Common Stock (which will be determined in a manner consistent with the
determination of the Exchange Ratio) and (y) cash based on a pro rata portion of
$27.50 (the 'Alternative Consideration'). The Merger Agreement provides that in
the event the Merger is not consummated prior to certain dates, holders of
shares of Revco Common Stock will be entitled to receive interest on the
consideration payable to them in the Merger at rates set forth in the Merger
Agreement. Following the Merger, Revco will become a wholly owned subsidiary of
Rite Aid.
<PAGE>
     The combination of Rite Aid and Revco will create the preeminent retail
drugstore chain in the United States. This transaction will nearly double our
revenues and number of stores. Our significant investment in technology and
infrastructure coupled with our innovative management changes have prepared us
to seize the competitive advantages this Merger represents. We anticipate a
quick and smooth integration of the two companies.
 
     The Merger will increase Rite Aid's competitive advantage in our
prescription benefits management subsidiary, Eagle Managed Care. The addition of
Revco's mail order capacity, as well as the increased number of outlets
available in the combined entity, complements and broadens Rite Aid's managed
healthcare delivery system. This expanded capacity is important leverage in
attracting new contracts to Rite Aid.
 
     We will be the best-positioned retail drugstore chain in the country to
compete with the three large vertically integrated pharmacy benefit managers
owned by the major pharmaceutical manufacturers. This combination should allow
Rite Aid to offer customers the most competitive pharmacy prescription prices
and services.
 
     YOUR BOARD OF DIRECTORS HAS UNANIMOUSLY DETERMINED THAT THE MERGER IS
ADVISABLE, FAIR TO AND IN THE BEST INTERESTS OF THE STOCKHOLDERS OF RITE AID AND
HAS APPROVED THE MERGER AGREEMENT AND ACCORDINGLY RECOMMENDS THAT RITE AID
STOCKHOLDERS VOTE IN FAVOR OF THE SHARE ISSUANCE.
 
     Your vote is important, regardless of the number of shares you own.

Approval of the Share Issuance requires the affirmative vote of a majority of
the votes cast by all stockholders entitled to vote at the Rite Aid Special
Meeting. The Notice of Special Meeting and Proxy Statement accompanying this
letter describe the proposed transactions more fully and include other
information about Rite Aid, Sub and Revco. Please give this information your
careful attention.
 
     Accordingly, on behalf of your Board of Directors, I urge you to complete,
date and sign the accompanying proxy and return it promptly in the enclosed
postage-paid envelope. This will not prevent you from attending the Rite Aid
Special Meeting or voting in person, but will assure that your vote is counted
if you are unable to attend the Rite Aid Special Meeting. You may revoke your
proxy at any time by filing a written notice of revocation with, or delivering a
duly executed proxy bearing a later date to, the Secretary of Rite Aid at Rite
Aid's main office prior to the Rite Aid Special Meeting or by attending the Rite
Aid Special Meeting and voting in person.
 
     On behalf of your Board of Directors, I thank you for your support and urge
you to vote FOR approval of the Share Issuance.
 
                                          Sincerely,
                                          Martin L. Grass
                                          Chairman and Chief Executive Officer

                                PROXY STATEMENT
    
 
   
     This Proxy Statement ('Proxy Statement') is being furnished to the holders
of common stock, par value $1.00 per share ('Rite Aid Common Stock'), of Rite
Aid Corporation, a Delaware corporation ('Rite Aid'), in connection with the
solicitation of proxies by the Board of Directors of Rite Aid (the 'Rite Aid
Board') for use at a Special Meeting of Stockholders of Rite Aid to be held at
the Radisson Hotel, 1150 Camp Hill Bypass, Camp Hill, Pennsylvania on Thursday,
March 28, 1996, at 10:00 a.m., local time, and at any and all adjournments or
postponements thereof (the 'Rite Aid Special Meeting') for the purposes
described herein.
    
 
     This Proxy Statement relates to the Agreement and Plan of Merger, dated as
of November 29, 1995 (the 'Merger Agreement'), by and among Rite Aid, Ocean
Acquisition Corporation, a Delaware corporation and a wholly owned subsidiary of
Rite Aid ('Sub'), and Revco D.S., Inc., a Delaware corporation ('Revco'), which
provides for the merger (the 'Merger') of Sub with and into Revco, with Revco
surviving as a wholly owned subsidiary of Rite Aid. Subject to the terms and
conditions of the Merger Agreement, if the Merger is consummated, each share of
common stock, par value $.01 per share, of Revco ('Revco Common Stock') issued
and outstanding immediately prior to the effective time of the Merger (other
than shares of Revco Common Stock owned by Revco as treasury stock and other
than shares of Revco Common Stock owned by Rite Aid and Sub and other than
shares of Revco Common Stock held by holders who have properly exercised and
perfected appraisal rights, if applicable ('Dissenting Revco Shares'), under the
Delaware General Corporation Law) shall by virtue of the Merger and without any
action on the part of the holder thereof be converted into either (x) the right
to receive a number of duly authorized, validly issued, fully paid and
nonassessable shares of Rite Aid Common Stock determined as set forth herein
(the 'Exchange Ratio'); provided that Rite Aid will not issue more than 1.125 or
fewer than .91666 shares of Rite Aid Common Stock per share of Revco Common
Stock or (y) if the Alternative Consideration (as defined below) is applicable,
then the right to receive the Alternative Consideration, plus, in each of clause
(x) and (y) above, any Additional Consideration (as defined below). Each share
of Rite Aid Common Stock will be issued with one associated preferred stock
purchase right (a 'Right').
 
   
     The per share value of Rite Aid Common Stock which stockholders of Revco
will receive in the Merger will be determined during a randomly selected
fifteen-day pricing period (the 'Pricing Period') during the forty trading days
ending five days before the Revco Special Meeting to consider the Merger.
PROMPTLY FOLLOWING THE CLOSE OF THE PRICING PERIOD, RITE AID AND REVCO WILL
ISSUE A JOINT PRESS RELEASE ANNOUNCING THE EXCHANGE RATIO. IF THERE IS TO BE ANY
CASH ADJUSTMENT AMOUNT (AS DESCRIBED HEREIN), SUCH PRESS RELEASE WILL ALSO
DISCLOSE THAT AMOUNT. ONCE THE PRICING PERIOD HAS ENDED, STOCKHOLDERS MAY ALSO
CALL MACKENZIE PARTNERS, INC. TOLL FREE AT 1-800-322-2885 OR COLLECT AT (212)
929-5500 TO LEARN THE EXCHANGE RATIO AND THE CASH ADJUSTMENT AMOUNT, IF ANY. In

the Merger, stockholders of Revco will receive one share of Rite Aid Common
Stock if the average per share value of Rite Aid Common Stock during the Pricing
Period is $27.50. If the average per share value of Rite Aid Common Stock
determined during the Pricing Period is greater than $27.50, stockholders of
Revco will receive, for each share of Revco Common Stock, that amount of Rite
Aid Common Stock having a value so determined of $27.50 plus 50% of such
increase in market value of Rite Aid Common Stock over $27.50, provided that in
no event will Rite Aid issue fewer than .91666 shares of Rite Aid Common Stock
for each share of Revco Common Stock. Similarly, if the average per share value
of Rite Aid Common Stock determined during the Pricing Period is less than
$27.50, stockholders of Revco will receive, for each share of Revco Common
Stock, that amount of Rite Aid Common Stock having a value so determined of
$27.50 less 50% of such decrease in market value of Rite Aid Common Stock below
$27.50, provided that in no event will Rite Aid issue more than 1.125 shares of
Rite Aid Common Stock for each share of Revco Common Stock. Alternatively, if
the average per share value of the Rite Aid Common Stock determined during the
Pricing Period is less than $27.50, Rite Aid will have the option of delivering,
for each share of Revco Common Stock, one share of Rite Aid Common Stock plus
cash (the 'Cash Adjustment Amount') in an amount equal to 50% of such decrease
in market value of Rite Aid Common Stock below $27.50, provided that in no event
will more than $2.75 per share of Revco Common Stock be paid in cash.
    
 
     In the event that at the Rite Aid Special Meeting the stockholders of Rite
Aid do not approve the issuance of Rite Aid Common Stock pursuant to the Merger
Agreement (the 'Share Issuance'), but all conditions to the Merger are otherwise
satisfied or waived (if permissible), Revco, Rite Aid and Sub will nonetheless
consummate the Merger and shares of Revco Common Stock issued and outstanding
immediately prior to the effective time (the 'Effective Time') of the Merger
(other than shares of Revco Common Stock owned by Revco as treasury stock and
other than shares of Revco Common Stock owned by Rite Aid and Sub and other than
Dissenting Revco Shares) will, at the Effective Time, be converted into the
right to receive a combination of (x) shares of Rite Aid Common Stock which will
represent in the aggregate 19.9% of the then outstanding shares of Rite Aid
Common Stock (which will be determined in a manner consistent with the
determination of the Exchange Ratio) and (y) cash based on a pro rata portion of
$27.50 (collectively, the 'Alternative Consideration'). The Merger Agreement
provides that in the event the Merger is not consummated prior to certain dates,
holders of shares of Revco Common Stock will be entitled to receive interest on
the consideration payable to them in the Merger at rates set forth in the Merger
Agreement.
 
   
     This Proxy Statement and the accompanying form of proxy are first being
mailed to stockholders of Rite Aid on or about February 20, 1996.
    
 
                            ------------------------
 
   
             The date of this Proxy Statement is February 16, 1996.

  Revco Special Meeting.
 
     Purpose.  A Special Meeting of Stockholders of Revco (the 'Revco Special
Meeting') will be held as soon as practicable following the Rite Aid Special
Meeting to consider and vote upon a proposal to approve and adopt the Merger
Agreement, which provides for the Merger of Sub with and into Revco, with Revco
surviving as a wholly owned subsidiary of Rite Aid. The stockholders of Revco
will also consider and take action upon any other business which may properly be
brought before the Revco Special Meeting. See 'REVCO SPECIAL MEETING.'
 
THE MERGER
 
  General.
 
   
     On December 4, 1995, Sub commenced the Offer. On December 11, 1995, Rite
Aid and Revco filed notifications and report forms under the Hart-Scott-Rodino
Antitrust Improvements Act of 1976, as amended (the 'HSR Act') with the Federal
Trade Commission (the 'FTC') and the Antitrust Division of the United States
Department of Justice (the 'Antitrust Division'). On December 27, 1995, Rite Aid
and Revco received a request for additional information (the 'Second Request')
from the FTC. On January 4, 1996, Sub extended the Offer in order to comply with
the Second Request. The Offer is presently scheduled to expire on February 23,
1996 and Rite Aid reserves the right to extend the Offer until the expiration of
the waiting period under the HSR Act.
    
 
     At the Effective Time of the Merger, each share of Revco Common Stock
issued and outstanding immediately prior to the Effective Time, other than
shares of Revco Common Stock owned by Revco as treasury stock and any shares of
Revco Common Stock owned by Rite Aid, Sub or any other direct or indirect wholly
owned subsidiary of Rite Aid (and, if the Alternative Consideration, as defined
below, is applicable, other than shares of Revco Common Stock held by holders

who have properly exercised and perfected their appraisal rights ('Dissenting
Revco Shares'), under the Delaware General Corporation Law (the 'DGCL')), shall
by virtue of the Merger and without any action on the part of the holder thereof
be converted into either (x) the right to receive a number of duly authorized,
validly issued, fully paid and nonassessable shares of Rite Aid Common Stock,
determined as set forth below (the 'Exchange Ratio'); provided that Rite Aid
shall not issue more than 1.125 or fewer than .91666 shares of Rite Aid Common
Stock per share of Revco Common Stock or (y) if the Alternative Consideration
(as defined below) is applicable, then the right to receive the Alternative
Consideration, plus, in each of clause (x) and (y) above, any Additional
Consideration (as defined below). Each share of Rite Aid Common Stock will be
issued with one associated preferred stock purchase right (a 'Right') in
accordance with the Shareholder Rights Agreement, dated as of April 15, 1989,
between Rite Aid and Harris Trust Company of New York (the 'Rights Agreement').
 
   
     The per share value of the Rite Aid Common Stock which stockholders of
Revco would receive in the Merger will be determined during a randomly selected
fifteen-day pricing period (the 'Pricing Period') during the forty trading days
ending five days before the Revco Special Meeting. PROMPTLY FOLLOWING THE CLOSE
OF THE PRICING PERIOD, RITE AID AND REVCO WILL ISSUE A JOINT PRESS RELEASE
ANNOUNCING THE EXCHANGE RATIO. IF THERE IS TO BE ANY CASH ADJUSTMENT AMOUNT (AS
DEFINED BELOW), SUCH PRESS RELEASE WILL ALSO DISCLOSE THAT AMOUNT. ONCE THE
PRICING PERIOD HAS ENDED, STOCKHOLDERS MAY ALSO CALL MACKENZIE PARTNERS, INC.
TOLL FREE AT 1-800-322-2885 OR COLLECT AT (212) 929-5500 TO LEARN THE EXCHANGE
RATIO AND THE CASH ADJUSTMENT AMOUNT, IF ANY.
    
 
     In the Merger, stockholders of Revco will receive one share of Rite Aid
Common Stock if the average value per share of Rite Aid Common Stock during the
Pricing Period is $27.50. If the average value per share of Rite
 
                                       7
<PAGE>
Aid Common Stock determined during the Pricing Period is greater than $27.50,
stockholders of Revco will receive, for each share of Revco Common Stock, that
amount of Rite Aid Common Stock having a value so determined of $27.50 plus 50%
of such increase in market value of Rite Aid Common Stock over $27.50, provided
that in no event will Rite Aid issue fewer than .91666 shares of Rite Aid Common
Stock for each share of Revco Common Stock. Similarly, if the average per share
value of Rite Aid Common Stock determined during the Pricing Period is less than
$27.50, stockholders of Revco will receive, for each share of Revco Common
Stock, that amount of Rite Aid Common Stock having a value so determined of
$27.50 less 50% of such decrease in market value of Rite Aid Common Stock below
$27.50, provided that in no event will Rite Aid issue more than 1.125 shares of
Rite Aid Common Stock for each share of Revco Common Stock. Alternatively, if
the average per share value of the Rite Aid Common Stock determined during the
Pricing Period is less than $27.50, Rite Aid will have the option of delivering,
for each share of Revco Common Stock, one share of Rite Aid Common Stock plus
cash (the 'Cash Adjustment Amount') in an amount equal to 50% of such decrease
in market value of Rite Aid Common Stock below $27.50, provided that in no event
will more than $2.75 per share of Revco Common Stock be paid in cash.
 
     In the event the Merger is not consummated prior to April 29, 1996, and

Revco has not materially breached the Merger Agreement (other than by acts
caused or permitted by Rite Aid), then the stockholders of Revco will be
entitled to receive interest on the amount of the consideration that they
receive pursuant to the immediately preceding paragraph and the immediately
following paragraph (such consideration and interest thereon being referred to
herein as the 'Merger Consideration'), from April 29, 1996 until the earlier of
the Effective Time or June 30, 1996, calculated at an annual rate equal to the
prime rate of interest (as announced from time to time by Morgan Guaranty Trust
Company of New York). In the event Rite Aid and/or Sub, in violation of their
obligations under the Merger Agreement, fail or refuse to consummate the Merger
on or prior to June 30, 1996 and Revco has not materially breached the Merger
Agreement (other than by acts caused or permitted by Rite Aid), then, in
addition to any rights or remedies that Revco and its stockholders otherwise
have in law or at equity as a result thereof, the stockholders of Revco will be
entitled to receive interest from June 30, 1996 on the amount of the Merger
Consideration not paid until such Merger Consideration is paid, calculated at
the annual rate of the higher of (i) the prime rate of interest (as announced
from time to time by Morgan Guaranty Trust Company of New York) plus 300 basis
points or (ii) the amount otherwise permitted by law. Any additional
consideration paid or payable pursuant to this paragraph is referred to herein
as 'Additional Consideration.' See 'MERGER AGREEMENT--Conversion of Revco Common
Stock.'
 
     In the event that at the Rite Aid Special Meeting the stockholders of Rite
Aid do not approve the issuance of Rite Aid Common Stock pursuant to the Merger
Agreement (the 'Share Issuance'), but all conditions to the Merger are otherwise
satisfied or waived (if permissible), Revco, Rite Aid and Sub will nonetheless
consummate the Merger and shares of Revco Common Stock issued and outstanding
immediately prior to the Effective Time (other than shares of Revco Common Stock
held in treasury and shares of Revco Common Stock owned by Rite Aid and its
subsidiaries and other than Dissenting Revco Shares) will, at the Effective
Time, be converted into the right to receive a combination of (x) shares of Rite
Aid Common Stock which will represent in the aggregate 19.9% of the then
outstanding shares of Rite Aid Common Stock (which will be determined in a
manner consistent with the determination of the Exchange Ratio) and (y) cash
based on a pro rata portion of $27.50 (collectively, the 'Alternative
Consideration'). See 'MERGER AGREEMENT--Conditions to the Merger.'
 
     The DGCL does not require the Rite Aid Board to submit the Merger Agreement
to a vote of the Rite Aid stockholders. Accordingly, the stockholders of Rite
Aid are not being asked to consider and vote upon the adoption and approval of
the Merger Agreement at the Rite Aid Special Meeting. At the Rite Aid Special
Meeting, the stockholders of Rite Aid will consider and vote upon the Share
Issuance as required by a rule of the New York Stock Exchange. Pursuant to such
New York Stock Exchange rule, a company may not issue 20% or more of the
company's outstanding shares without a vote of the company's stockholders.
 
     The Rite Aid Board has determined that the Merger is advisable, fair to and
in the best interests of the stockholders of Rite Aid and determined to proceed
with the Merger even if the Share Issuance is not approved by the Rite Aid
stockholders. Therefore, in the event that the Rite Aid stockholders do not
approve the Share Issuance but all conditions to the Merger are otherwise
satisfied or waived (if permissible), the Alternative Consideration contemplated
by the Merger Agreement will be paid to Revco's stockholders upon consummation

 
                                       8
<PAGE>
of the Merger and approximately 19.9% of Rite Aid's current issued and
outstanding shares will be issued in the Merger.
 
  Rite Aid's Reasons for the Merger; Recommendation of the Rite Aid Board.
 
     The Rite Aid Board has unanimously determined that the Merger is advisable
and fair to and in the best interests of the stockholders of Rite Aid and has
approved the Merger Agreement. THE RITE AID BOARD UNANIMOUSLY RECOMMENDS THAT
THE STOCKHOLDERS OF RITE AID VOTE IN FAVOR OF THE SHARE ISSUANCE AT THE RITE AID
SPECIAL MEETING. In reaching its conclusion, the Rite Aid Board considered, a
number of factors, including, without limitation, the following:
 
          o the judgment, advice and analyses of its management;
 
          o the analyses prepared by Donaldson, Lufkin & Jenrette Securities
            Corporation ('DLJ'), and the oral opinion of DLJ presented to the
            Rite Aid Board on November 28, 1995 and confirmed in writing on
            November 29, 1995, to the effect that the consideration to be paid

            purchasing power, closure of Revco's corporate headquarters and

            overhead, elimination of redundant advertising expenditures, the

  Revco's Reasons for the Merger; Recommendation of the Revco Board.
 
     PRIOR TO THE EXECUTION OF THE MERGER AGREEMENT, THE BOARD OF DIRECTORS OF
REVCO (THE 'REVCO BOARD') UNANIMOUSLY DETERMINED (WITH ONE DIRECTOR ABSENT AND
TWO DIRECTORS ABSTAINING) THAT THE MERGER IS FAIR TO, AND IN THE BEST INTERESTS
OF, THE STOCKHOLDERS OF REVCO, APPROVED THE MERGER AGREEMENT, AND RECOMMENDED
THAT THE STOCKHOLDERS OF REVCO VOTE IN FAVOR OF APPROVAL AND ADOPTION OF THE
MERGER AGREEMENT AT THE REVCO SPECIAL MEETING. In reaching its conclusion, the
Revco Board considered a number of factors, including, without limitation, the
following:
 
          o the terms and conditions of the Merger Agreement, including the
            amount and form of Merger Consideration;
 
          o the fact that the value of the shares of Rite Aid Common Stock to be
            received for each share of Revco Common Stock in the Merger will
            increase to the extent the average value of Rite Aid Common Stock is
            greater than $27.50 per share during the Pricing Period and will
            decrease if the average value of the Rite Aid Common Stock is less
            than $27.50 per share during the Pricing Period;
 
          o presentations by management of Revco (at a board meeting held on
            November 28, 1995, and at previous board meetings) regarding the
            financial condition, results of operations, business and prospects

            of Revco, including the prospects of Revco if it remained
            independent;
 
          o the fact that upon consummation of the Offer, Rite Aid and/or Sub
            will own at least 50.1% of the outstanding shares of Revco Common
            Stock and have agreed to vote in favor of the approval and adoption
            of the Merger Agreement, and, therefore, a vote in favor of the
            approval and adoption of the Merger Agreement would be assured
            without the vote of any other holder of shares of Revco Common
            Stock;
 
          o the historical market prices for the shares of Revco Common Stock,
            particularly the fact that the $27.50 per share price in the Offer
            represented (x) a premium of approximately 6.8% over the closing
            price of $25.75 for the shares of Revco Common Stock on November 27,
            1995, the last trading day prior to the approval of the Merger
            Agreement, and (y) a higher price than the shares of Revco Common
            Stock had ever traded;
 
          o the expected future trading values of the shares of Revco Common
            Stock in light of, among other things, the historical trading
            multiples of other companies in Revco's line of business;
 
          o the analyses prepared by Morgan Stanley & Co. Incorporated ('Morgan
            Stanley') and the oral opinion of Morgan Stanley presented to the
            Revco Board on November 28, 1995 and confirmed in writing on
            November 29, 1995 to the effect that, as of such date and based upon
            its review and analysis and subject to the limitations set forth
            therein, the consideration to be received by the holders of Revco
            Common Stock pursuant to the Offer and the Merger, taken together,
            is fair from a financial point of view to such holders. See 'THE
            MERGER--Opinion of Morgan Stanley;'
 
          o the fact that the Merger offers the opportunity for substantial
            synergies and the transaction structure allows Revco stockholders
            who receive Rite Aid Common Stock to participate in those synergies
            through continued ownership of the combined company;
 
          o the views expressed by management and Morgan Stanley that there did
            not appear to be any other party with which Revco would be as good a
            strategic fit as Rite Aid;
 
          o the fact that the Stockholder agreed to tender all of its shares of
            Revco Common Stock in the Offer and to support the Merger Agreement;
 
          o the fact that the Merger is not conditioned on the availability of
            financing;
 
          o the fact that the Merger Agreement, which prohibits Revco, its
            subsidiaries or its affiliates from initiating, soliciting or
            encouraging any potential acquisition proposal, does permit Revco to
            furnish information to and participate in discussions or
            negotiations with any third party if certain conditions are
            satisfied;

 
                                       10
<PAGE>
          o the fact that if the Revco Board decided to accept an acquisition
            proposal by a third party, the Revco Board may terminate the Merger
            Agreement and pay Rite Aid a termination fee of $45 million, or
            approximately $.68 per issued and outstanding share, which the Revco
            Board did not believe would be a significant deterrent to a higher
            offer by a third party interested in acquiring Revco; and
 
          o the regulatory approvals required to consummate the Merger,
            including, among other things, antitrust approvals, and the
            prospects of receiving such approvals.
 
     See 'THE MERGER--Revco's Reasons for the Merger; Recommendation of the
Revco Board.'
 
  Opinion of Morgan Stanley.
 
     Morgan Stanley delivered its oral opinion to the Revco Board, which was
confirmed by its written opinion dated November 29, 1995 to the Revco Board, to
the effect that the consideration to be received by the holders of Revco Common
Stock pursuant to the Offer and the Merger, taken together, is fair from a
financial point of view to such holders. The full text of the Morgan Stanley
opinion, which sets forth a description of the assumptions made, matters
considered and limitations on the review undertaken, is attached hereto as Annex
C. See 'THE MERGER--Opinion of Morgan Stanley.'
 
Certain Advantages and Disadvantages of the Merger.
 
     In considering whether to approve the Share Issuance, stockholders of Rite
Aid should consider the following advantages and disadvantages.
 
     Advantages.  The Merger will provide significant benefits to Rite Aid and
Revco and each of their respective stockholders. The Merger will create
substantial opportunities for synergies and will allow the combined company to
compete more effectively in a marketplace that is becoming increasingly
competitive.
 
     In addition, the Rite Aid Board has determined that the Merger is
advisable, fair to and in the best interests of the Rite Aid stockholders and
has approved the Merger Agreement.
 
     Moreover, the Merger is expected to be accretive to Rite Aid's earnings per
share by the end of the first year of operations following the Merger.
Similarly, Rite Aid's management estimates, based on a preliminary review of
Revco's business and operations, that the Merger will result in approximately
$156 million of quantifiable annual cost savings, including improvement in gross
margins through enhanced purchasing power, closure of Revco's corporate
headquarters and overlapping distribution facilities, elimination of duplicative
overhead, elimination of redundant advertising expenditures, the consolidation
of data centers and improved communications systems and a working capital
benefit from the consolidation of warehouse inventories.
 

     Further, DLJ has delivered its opinion to the Rite Aid Board to the effect
that the consideration to be paid by Rite Aid pursuant to the Merger Agreement,
taken as a whole, is fair to the stockholders of Rite Aid from a financial point
of view. Similarly, Morgan Stanley has delivered its written opinion to the
Revco Board to the effect that the aggregate consideration to be received by the
holders of shares of Revco Common Stock pursuant to the Offer and the aggregate
consideration to be received by the holders of shares of Revco Common Stock
pursuant to the Merger, taken together, are fair from a financial point of view
to such holders.
 
     Disadvantages.  The Rite Aid Board considered the fact that Rite Aid would
be a more leveraged company in the event that the Share Issuance was not
approved by Rite Aid's stockholders and the Merger was consummated using the
Alternative Consideration.
 
     In determining that the Merger is advisable and in the best interests of
its stockholders, the Rite Aid Board considered the cost savings, operating
efficiencies and other synergies expected to result from the consummation
thereof. The consolidation of functions, the integration of departments, systems
and procedures and the relocation of staff present significant management
challenges. There can be no assurance that such actions will be successfully
accomplished as rapidly as currently expected. Moreover, although the primary
purpose of such actions will be to realize direct cost savings and other
operating efficiencies, there can be no assurance of the extent to which such
cost savings and efficiencies will be achieved.
 
   
     If the stockholders of Rite Aid approve the Share Issuance and assuming a
one-for-one Exchange Ratio, the current stockholders of Rite Aid would own
approximately 72.7% of the then outstanding shares of Rite Aid Common Stock
after the Merger.
    
 
                                       11
<PAGE>
   
     Rite Aid also expects to take a pre-tax charge to earnings estimated to be
in the range of $150 million to $175 million to cover the cost of integrating
the two companies. See Note (n) of Notes to Unaudited Pro Forma Condensed
Consolidated Financial Data for a discussion of such merger and integration
charges. There can be no assurance, however, that the amount of such charge will
not increase as Rite Aid's integration plan is further developed and more
accurate estimates become possible or as to the amount of the after-tax cost of
such charge. See 'THE MERGER--Certain Advantages and Disadvantages of the
Merger.'
    
 
  Plans for Revco.
 
   
     It is expected that the business and operations of Revco will be integrated
into the operations of Rite Aid as rapidly as practicable following the Merger.
Rite Aid intends to close Revco's corporate headquarters at 1925 Enterprise
Parkway, Twinsburg, Ohio (the 'Headquarters') within twelve months following

consummation of the Merger and to integrate Revco's corporate headquarters
operations into Rite Aid's operations. Rite Aid also expects to take a pre-tax
charge to earnings estimated to be in the range of $150 million to $175 million
to cover the cost of integrating the two companies. Rite Aid anticipates that
only a small percentage of the combined stores of Rite Aid and Revco will be
closed. A decision on which stores will be closed is not expected to be made
until after the consummation of the Merger. In addition, Rite Aid will continue
to evaluate the business and operations of Revco after the consummation of the
Merger, and will take such further actions as it deems appropriate under the
circumstances then existing. See 'THE MERGER--Plans for Revco.'
    
 
  Background of the Merger.
 
     For a description of the background of the Merger, see 'THE
MERGER--Background of the Merger.'
 
  Interests of Certain Persons.
 
     Existing Employment Agreements.  Revco maintains employment agreements
with, among others, its eight executive officers ('Group A Executives') and
fifteen other officers (collectively with the Group A Executives, the 'Covered
Executives' or, individually, a 'Covered Executive'), with one form of agreement
for executive officers and one form of agreement for non-executive officers.
Except for the severance periods, the forms of these agreements are
substantially similar.
 
     The agreements provide, among other things, for the payment of base salary
and participation in Revco's bonus plan and provides that the employee will be
eligible to participate in Revco's other employee benefit programs for the
provision of welfare and other benefits.
 
     In addition, the agreements provide for the payment of an employee's base
salary and the continuation of other benefits for a specified period upon
termination of employment by Revco other than for gross misconduct or by the
employee for good reason. The severance period for Group A Executives is two
years and, for the other fifteen officers ('Group B Executives'), is one year.
See 'THE MERGER--Interests of Certain Persons.'
 
     Economic Value Added (EVA) Incentive Plan (the 'Bonus Plan').  Each of the
Covered Executives is eligible to participate in the Bonus Plan. Awards pursuant
to the Bonus Plan are based upon the achievement of a combination of performance
objectives by Revco and the individual participant. Each participant in the
Bonus Plan is credited with bonus units equal to his base salary multiplied by a
target bonus percentage. If the target bonus is exceeded by a specified amount,
the excess is deposited into a bonus bank on behalf of the individual
participant for the following year. See 'THE MERGER--Interests of Certain
Persons.'
 
     Defined Benefit Plan.  The Revco Retirement Income Plan and Trust, as
amended ('Pension Plan'), is a defined benefit pension plan generally covering
employees of Revco, other than those covered by collective bargaining agreements
that provide for pension benefits.
 

     On reaching normal retirement at or after age 65, a participant is
generally entitled to receive a monthly retirement benefit for life. Alternative
actuarially equivalent forms of benefit payments are provided for in the Pension
Plan. Vesting under the Pension Plan occurs after five years of service (with no
vesting where less than five years of service has been completed).
 
     The annual retirement benefit at the normal retirement age of at least 65
is equal to an amount which, when added to the participant's social security
benefit, is the product of the employee's average earnings for the last five
years of his service and the applicable percentage. If the employee has fewer
than 30 years of credited
 
                                       12
<PAGE>
service with Revco, the benefit determined by this formula is reduced by a
percentage determined substantially by the ratio of the number of years of
credited service to 30. A participant who has attained age 55 and has completed
five years of service may elect early retirement with reduced monthly benefit
payments. See 'THE MERGER--Interests of Certain Persons.'
 
     Supplemental Retirement and Survivor Benefit Plan (the 'SERP').  Each of
the Covered Executives participates in the SERP, which provides supplemental
retirement benefits generally commencing upon either (i) retirement or
disability at age sixty, or (ii) upon termination of employment at age
sixty-five. The basic supplemental benefit is an amount that, when added to
other benefits (pension plan benefits, social security benefits and other
monthly retirement income as provided), equals 70% of a participant's final
salary. The SERP benefit is reduced for early retirement. Upon execution of an
individual agreement under the SERP, a participant is 50% vested. Thereafter, a
participant vests in his SERP benefits at a rate of 10% each year. See 'THE
MERGER--Interests of Certain Persons.'
 
     Split Dollar Plan.  Each of the Covered Executives participates in the
Split Dollar Plan. See 'THE MERGER--Interests of Certain Persons.'
 
     1992 Long-Term Incentive Plan (the 'LTIP').  Each of the Covered Executives
participates in the LTIP, which provides for the grant of incentive and
non-qualified stock options, reload options, stock appreciation rights,
restricted stock awards, stock bonus awards and performance plan awards. In the
event of a 'change in control,' as defined in the LTIP, the options granted to
Revco's officers become fully exercisable. The consummation of the Offer
constitutes a 'change in control' for purposes of the LTIP.
 
     The estimated amount of gain associated with the options of Group A
Executives that vest upon a 'change in control' is:
 
<TABLE>
<S>                                                            <C>
Mr. Hoven...................................................   $5,098,674
Mr. Bellini.................................................   $1,940,324
Mr. Hagan...................................................   $  797,095
Mr. Mastrian................................................   $1,357,569
Mr. Coffey..................................................   $  438,627
Mr. Gropp...................................................   $  322,573

Mr. Nichols.................................................   $  758,784
Mr. Staph...................................................   $  942,912
</TABLE>
 
     The estimated aggregate amount of gain associated with the options of Group
B Executives that vest upon a 'change in control' is approximately $3,200,000.
See 'THE MERGER--Interests of Certain Persons.'
 
     1992 Non-Employee Directors' Stock Option Plan (the 'Non-Employee
Directors' Plan').  All of the directors who are not officers or key employees
of Revco are eligible to participate in the Non-Employee Directors' Plan, which
provides for the grant of options to purchase shares of Revco Common Stock. The
consummation of the Offer constitutes a 'change in control' for purposes of the
Non-Employee Directors' Plan. The estimated aggregate amount of gain associated
with the options of non-employee directors that vest upon a 'change in control'
is approximately $577,000. See 'THE MERGER--Interests of Certain Persons.'
 
     Employee Stock Purchase Plan (the 'ESPP').  Each of the Covered Executives
is eligible to participate in the ESPP, which permits participants to purchase
Revco's common stock at the lesser of (a) 85% of the fair market value of the
stock on the first day of the offering period, or (b) 85% of the fair market
value of the stock on the last day of the offering period. See 'THE
MERGER--Interests of Certain Persons.'
 
     Treatment of Stock Options.  The Merger Agreement provides that, effective
as of the Effective Time, each option granted by Revco to purchase Revco Common
Stock that is outstanding and unexercised (each a 'Revco Stock Option') will
cease to represent a right to acquire Revco Common Stock and will be converted
automatically into an option to purchase shares of Rite Aid Common Stock. The
number of shares of Rite Aid Common Stock subject to the new option shall be
determined in a manner that preserves both (i) the aggregate gain (or loss) on
Revco Stock Options immediately prior to the Effective Time and (ii) the ratio
of the exercise price per share subject to Revco Stock Options to the fair
market value (determined immediately prior to the Effective Time) per share
subject to such option, provided that any fractional shares of Rite Aid Common
Stock resulting from such determination will be rounded down to the nearest
share. The Merger Agreement also provides that, effective as of the Effective
Time, the surviving corporation will assume each Revco Stock Option
 
                                       13
<PAGE>
agreement, each as amended, as provided therein. The duration, vesting and other
terms of the new options will be the same as the Revco Stock Options that they
replace, except that all references to Revco shall be deemed to be references to
Rite Aid.
 
     The Merger Agreement further provides that, notwithstanding the immediately
preceding paragraph, outstanding vested options under the LTIP held by Covered
Executives, including options that become vested in connection with a 'change in
control' under the terms of existing award agreements under the LTIP, will,
effective as of the Effective Time, become exercisable under a cashless exercise
procedure made available by Revco.
 
     The Merger Agreement provides that, effective as of the Effective Time, the

Option Plans will terminate and the provisions in any other plan, program,
agreement or arrangement providing for the issuance or grant of any other
interest in respect of the capital stock of Revco or any of its subsidiaries,
will be deleted. See 'THE MERGER--Interests of Certain Persons.'
 
     Bonus; Severance Benefits.  Pursuant to the Merger Agreement, as soon as
practicable following the earlier of (i) the Effective Time and (ii) the end of
Revco's 1996 fiscal year, Revco will pay, pursuant to the terms of the Bonus
Plan as modified by the terms of the Merger Agreement, bonuses for fiscal year
1996, calculated based on Revco's financial results as of February 10, 1996, and
annualized to equal a bonus for a twelve month period.
 
     With respect to the Covered Executives, effective as soon as practicable
following the Effective Time (or if later, the date of termination of employment
of the Covered Executive), the Merger Agreement provides that Revco will pay to
each Covered Executive severance payments (the 'Severance Payments'), on a basis
consistent with Rite Aid's executive payroll practices, based on one of the two
formulae set forth below, pursuant to elections made by each Covered Executive
prior to the Effective Time:
 
          (i) Severance Payments equal to, on an annualized basis, 'Base Pay'
     (as defined below), continuing for a period of three years with respect to
     Group A Executives, and for a period of 18 months with respect to Group B
     Executives. For purposes of this provision, 'Base Pay' means the highest
     base pay paid to the Covered Executive during any one of the 1994, 1995 or
     1996 fiscal years, provided that Base Pay for fiscal year 1996 will be
     calculated on an annualized basis; or
 
          (ii) Severance Payments equal to, on an annualized basis, 'Base Plus
     Bonus Pay' (as defined below), continuing for a period of two years with
     respect to Group A Executives, and for a period of one year with respect to
     Group B Executives. For purposes of this provision 'Base Plus Bonus Pay'
     means Base Pay plus the amount that would have been paid to the executive
     under the Bonus Plan for fiscal year 1995 as the targeted bonus (the '1995
     Target Bonus').
 
     In lieu of the Severance Payments described in clauses (i) and (ii) above,
Mr. Hoven and Mr. Mastrian will receive Severance Payments, continuing for three
years, equal to, on an annualized basis, Base Plus Bonus Pay.
 
     The estimated cost of providing the additional severance payments to Group
A Executives upon termination of employment is:
 
<TABLE>
<S>                                                            <C>
Mr. Hoven...................................................   $1,726,943
Mr. Bellini.................................................   $  420,000
Mr. Hagan...................................................   $  270,000
Mr. Mastrian................................................   $  701,496
Mr. Coffey..................................................   $  245,700
Mr. Gropp...................................................   $  203,963
Mr. Nichols.................................................   $  226,740
Mr. Staph...................................................   $  247,323
</TABLE>

 
     The aggregate estimated cost of providing the additional severance payments
to Group B Executives is $1,190,738.
 
     Pursuant to the Merger Agreement, each employee, other than any Covered
Executive, of Revco who is covered by Revco's severance pay plan as in effect on
November 1, 1995 (each, a 'Severance-Eligible Employee') and who is employed by
Revco immediately prior to the Effective Time and terminated for other than
Cause (as defined below), within twelve months following the Effective Time,
will be entitled to receive bi-weekly severance payments, made on a basis
consistent with Rite Aid's payroll practices, for a six month period
 
                                       14
<PAGE>
   
commencing on such Severance-Eligible Employee's date of termination of
employment, equal to, on an annualized basis, such Severance-Eligible Employee's
Base Pay; provided, however, that except for employees located at Revco's
headquarters such payments will be reduced (but not below zero) by the amount of
compensation such Severance-Eligible Employee receives from a subsequent
employer to the extent that such Severance-Eligible Employee is employed during
such six month period.
    
 
     For purposes of the Merger Agreement, 'Cause' will mean the conviction of
an employee or executive (as the case may be) for the commission of a felony,
including the entry of a guilty or nolo contendere plea, any willful, grossly
negligent or fraudulent action or inaction by an employee or executive, as the
case may be, or the employee's or executive's willful and continued failure to
substantially perform an employee's or executive's assigned duties. See 'THE

     SERP.  Pursuant to the Merger Agreement, each Revco employee who is (i)
covered by the SERP and (ii) actively employed by Revco, in either case,
immediately prior to the Effective Time (each, a 'SERP Executive') will be
eligible to receive benefits under the SERP based on the terms of the SERP, as
modified by the terms of the Merger Agreement.
 
     The estimated present value (using a 7.5% discount factor) of the
additional SERP and Split Dollar Plan benefits for the Group A Executives is:

</TABLE>
 
     The aggregate estimated present value (using a 7.5% discount factor) of the

additional SERP and Split Dollar Plan benefits for Group B Executives is
$762,150. See 'THE MERGER--Interests of Certain Persons.'
 
     Gross-Up Payments.  Pursuant to the Merger Agreement, Revco will provide
each Group A Executive with a cash gross-up payment to make such executive whole
for the excise taxes imposed on all benefits and other amounts paid or payable
to such executive on account of the transactions contemplated by the Merger
Agreement. With respect to all other employees of Revco who are entitled to
benefits and other amounts paid or payable to such employee on account of the
transactions contemplated by the Merger Agreement, Revco shall not be obligated
to pay or provide to any such employee any payments or benefits to the extent
that such payments or benefits would constitute a 'parachute payment' within the
meaning of Section 280G(b)(2)(A) of the Code. Based upon preliminary estimates,
the aggregate cost of the gross-up payments is expected to be between $6,000,000
and $9,000,000. See 'THE MERGER--Interests of Certain Persons.'
 
     ESPP.  Each Covered Executive who is subject to Section 16 ('Section 16')
of the Securities Exchange Act of 1934, as amended (the 'Exchange Act') will be
provided with a cash payment approximating the benefits that would be deprived
by reason of Section 16. Revco will amend the ESPP to provide that the option
period that was in effect as of November 29, 1995 will cease as soon as
practicable after such date. See 'THE MERGER--Interests of Certain Persons.'
 
     Other Benefits.  Revco will provide outplacement services from a recognized
outplacement provider selected by Rite Aid to all employees of Revco as of the
Effective Time who were based in Twinsburg, Ohio as of the Effective Time, and
are terminated without Cause within one year of the Effective Time.
 
     In addition, pursuant to the Merger Agreement, employees of Revco who
continue to be employed by Revco as of the Effective Time will receive employee
benefits comparable to those benefits provided to similarly situated employees
of Rite Aid. See 'THE MERGER--Interests of Certain Persons.'

  Indemnification.
 
     Pursuant to the terms of the Merger Agreement, Rite Aid has agreed that at
all times after the Effective Time, it will indemnify, or will cause Revco, as
the surviving corporation, and its subsidiaries to indemnify each director,
officer, employee or agent of Revco or any of Revco's subsidiaries, successors
and assigns (an 'Indemnified Party'), to the fullest extent permitted by law,
with respect to any claim, liability, loss, damage, judgment, fine, penalty,
amount paid in settlement or compromise, cost or expense, including reasonable
fees and expenses of legal counsel (whenever asserted or claimed) ('Indemnified
Liability') based in whole or in part on, or arising in whole or in part out of,
any matter existing or occurring at or prior to the Effective Time. See 'THE
MERGER--Indemnification'; and 'MERGER AGREEMENT--Directors' and Officers'
Insurance and Indemnification.'
 
  Estimated Synergies.
 
     Rite Aid regards the resulting consolidation of Revco and Sub as an
opportunity to achieve certain cost savings and synergies. Based on a

preliminary review of Revco's business and operations, Rite Aid currently
estimates that the Merger will result in approximately $156 million of
quantifiable annual cost savings, including the improvement in gross margins
through enhanced purchasing power, closure of Revco's corporate headquarters and
overlapping distribution facilities, elimination of duplicative overhead,
elimination of redundant advertising expenditures, the consolidation of data
centers and improved communications systems and a working capital benefit from
the consolidation of warehouse inventories. THE FOREGOING ESTIMATES OF COST
SAVINGS AND SYNERGIES ARE INHERENTLY SUBJECT TO SIGNIFICANT UNCERTAINTIES AND
CONTINGENCIES, MANY OF WHICH ARE BEYOND THE CONTROL OF RITE AID. THERE CAN BE NO
ASSURANCE THAT THEY WILL BE ACHIEVED AND ACTUAL SAVINGS AND SYNERGIES MAY VARY
MATERIALLY FROM THOSE ESTIMATED. THE INCLUSION OF SUCH ESTIMATES HEREIN SHOULD
NOT BE REGARDED AS AN INDICATION THAT RITE AID, SUB OR ANY OTHER PARTY CONSIDERS
SUCH ESTIMATES AN ACCURATE PREDICTION OF FUTURE EVENTS. See 'THE
MERGER--Estimated Synergies.'
 
  Conditions to the Merger.
 
     The obligations of Rite Aid and Revco to consummate the Merger are subject
to the satisfaction or waiver (where permissible) of various conditions,
including, among others, the absence of any order or legal restraint or
prohibition preventing the consummation of the Merger. See 'MERGER
AGREEMENT--Conditions to the Merger.'
 
  Other Legal Matters; Regulatory Approvals.
 
     General.  Except as otherwise disclosed herein, based upon its review of
publicly available information with respect to Revco and the review of certain
information furnished by Revco to Rite Aid, neither Sub nor Rite Aid is aware of
(i) any license or regulatory permit that appears to be material to the business
of Revco and its subsidiaries, taken as a whole, that might be adversely
affected pursuant to the Merger or (ii) any approval or other action by any
governmental, administrative or regulatory agency or authority, domestic or
foreign, that would be required for the consummation of the Merger. Should any
such approval or other action be required, Rite Aid and Sub currently
contemplate that such approval or action would be sought. Revco's pharmacists
and pharmacy technicians are required to be licensed by the appropriate state
board of pharmacy. Revco's stores and certain of Revco's distribution centers
are also registered with the Federal Drug Enforcement Administration. Many of
Revco's stores sell alcoholic beverages and are subject to various state and
local licensing requirements as a result. By virtue of these license and
registration requirements, Revco may be obligated to obtain certain governmental
consents and approvals in order to consummate the Merger.
 
     Antitrust.  Under the HSR Act and the regulations promulgated thereunder by
the FTC, the Offer may not be consummated until notifications have been given
and certain information has been furnished to the FTC and the Antitrust Division
and the applicable waiting period has expired or been terminated. The
consummation of the Offer is conditioned upon the expiration or termination of
the applicable waiting period under the HSR Act. On December 11, 1995, Rite Aid
and Revco filed notifications and report forms under the HSR Act with the FTC
and the Antitrust Division. On December 27, 1995, Rite Aid and Revco received a
request for additional
 

                                       16
<PAGE>
   
information (the 'Second Request') from the FTC. Rite Aid has submitted its
responses and certified to the FTC that it was in substantial compliance with
the Second Request as of February 7, 1996. Under the applicable HSR Act
regulations, the Offer may not be consummated until 10 days after Rite Aid has
substantially complied with the Second Request or the Second Request has been
withdrawn by the FTC and termination of the waiting period has been granted or
such later date as may be agreed to by Rite Aid on a voluntary basis. Rite Aid
has voluntarily agreed with the FTC to extend such 10 day waiting period through
Friday, February 23, 1996. At any time before or after the Effective Time, and
notwithstanding that the waiting period under the HSR Act has expired, any state
could take such action under its antitrust law as it deems necessary or
desirable in the public interest. Rite Aid has received requests for information
regarding antitrust issues from four state attorneys general concerning the
Merger. Rite Aid is cooperating with such attorneys general. See 'THE
MERGER--Other Legal Matters; Regulatory Approvals.'
    
 
ACCOUNTING TREATMENT
 
     The Merger will be accounted for under the 'purchase' method of accounting
in accordance with generally accepted accounting principles ('GAAP').
 
APPRAISAL RIGHTS FOR REVCO STOCKHOLDERS
 
     If only shares of Rite Aid Common Stock are issued in the Merger, then
Revco stockholders will not have any appraisal rights. However, in the event (i)
the Alternative Consideration or any Additional Consideration contemplated by
the Merger Agreement is applicable or (ii) that Rite Aid elects to pay any Cash
Adjustment Amount, under Section 262 of the DGCL ('Section 262'), any holder of
record of shares of Revco Common Stock who does not vote in favor of approval
and adoption of the Merger Agreement and delivers a demand for appraisal prior
to the vote of Revco's stockholders at the Revco Special Meeting on the Merger
Agreement has the right to obtain cash payment for the 'fair value' of his or
her shares at the Effective Time (excluding any element of value arising from
the accomplishment or expectation of the Merger). See 'THE MERGER--Appraisal
Rights.'

(1) The pro forma financial information has been prepared assuming the Merger
    occurred at the beginning of the respective periods using a one-for-one
    Exchange Ratio of shares of Rite Aid Common Stock for shares of Revco Common
    Stock.
 
(2) The per share amount used in the pro forma calculations were computed by
    adding the approximately 35,005,000 shares of Rite Aid Common Stock to be
    issued in the Merger to the actual number of outstanding shares of Rite Aid
    Common Stock for the respective periods.
 
(3) Equivalent pro forma data for Revco were computed by multiplying the pro
    forma combined per share data of Rite Aid by the Exchange Ratio, assuming an
    Exchange Ratio of 1.00.

- ------------------
(1) Primary earnings per share have been computed based on the weighted average
    number of shares of Rite Aid Common Stock outstanding during each of the
    following fiscal years (84,771,000 in fiscal year 1995, 87,972,000 in fiscal
    year 1994, 87,933,000 in fiscal year 1993, 86,917,000 in fiscal year 1992
    and 82,996,000 in fiscal year 1991) restated to reflect the June 17, 1991,
    two-for-one stock split. There were 83,816,000 weighted average shares

    outstanding during the thirty-nine week period ended December 2, 1995.
 
(2) On April 3, 1991, the Rite Aid Board declared a two-for-one stock split of
    the company's common stock, payable July 8, 1991, to shareholders of record
    at the close of business on June 17, 1991. The par value of $44,936,000 for
    the additional shares issued was transferred from the additional paid-in
    capital account to the common stock account. All share and per share data in
    these financial statements (for fiscal years ended February 27, 1993,
    February 29, 1992, and March 2, 1991) have been restated to reflect the
    stock split, except where otherwise noted.
 
(3) Depreciation and amortization expenses were $82,740,000 for fiscal year
    1995, $76,312,000 for fiscal year 1994, $71,998,000 for fiscal year 1993,
    $69,371,000 for fiscal year 1992 and $73,250,000 for fiscal year 1991.
    Depreciation and amortization generally are computed on a straight-line
    basis over the following estimated lives: Buildings, 30 to 45 years;
    Leasehold improvements, term of lease or useful lives of assets, whichever
    is shorter; and Equipment, 3 to 15 years. Accelerated methods are used for
    income tax purposes. As of March 4, 1995, land, buildings and related
    equipment with a carrying value of $11,285,000 were pledged to secure
    certain long-term debt totaling $10,812,000.
 
(4) As part of the corporate restructuring strategy, Rite Aid concentrated its
    focus and resources entirely on the drugstore segment and, therefore,
    authorized the sale of its four non-drugstore businesses. The businesses
    sold were ADAP, an auto parts retailer with 96 stores, Encore Books, which
    operated 98 stores, Concord Custom Cleaners which had 168 outlets and
    Sera-Tec Biologicals, which consisted of 33 plasma collection centers
    providing plasma for use in therapeutic and diagnostic products. During
    fiscal year 1995, Encore, Concord and Sera-Tec were sold. The net proceeds
    received amounted to $75,765,000 after taxes and expenses of $24,312,000.
    The resulting aggregate after-tax loss of $12,274,000 was recorded to the
    reserve for loss on disposal of discontinued operations and compares
    favorably to the $12,320,000 reserve amount originally provided for the sale
    of these three businesses. The remaining net reserve balance of $13,346,000
    as of March 4, 1995, is included with net current assets of discontinued
    operations on the balance sheet. Sera-Tec was sold to a group of investors
    that included Alex Grass, former Chairman and Chief Executive Officer of
    Rite Aid Corporation. As of March 4, 1995 the sale of ADAP was being
    negotiated and was subsequently completed in the first quarter of fiscal
    1996. Rite Aid believes that the remaining reserve amount for loss on
    disposal of ADAP is adequate. ADAP's net assets are segregated on the March
    4, 1995, balance sheet and primarily consist of inventories, property,
    leasehold improvements, store fixtures and equipment.
 
    A pre-tax provision of $42,000,000 for loss on disposal of these
    discontinued operations was recorded in the fourth quarter of fiscal year
    1994 and is shown on the consolidated statement of income net of a
    $16,380,000 income tax benefit. The provision includes after-tax income
    from operations during the phaseout period of $959,000.
 
    Net sales for the discontinued operations were $273,149,000, $251,462,000
    and $217,816,000 for fiscal years 1994, 1993 and 1992, respectively. The
    interest expense allocation was $4,490,000 in fiscal year 1994, $3,501,000

    in fiscal year 1993 and $3,358,000 in fiscal year 1992. Assets and
    liabilities of the discontinued operations have been reclassified to
    separately identify them on the consolidated balance sheet. The net current
    assets of discontinued operations principally consist of inventories and
    for fiscal year 1994 includes the $42,000,000 disposition reserve with
    applicable income tax benefit of $16,380,000. The net non-current assets of
    discontinued operations primarily consist of property, leasehold
    improvements, store fixtures and equipment. Prior fiscal years'
    consolidated financial statements and notes to the consolidated financial
    statements have been restated, except where otherwise noted, to reflect
    continuing operations.
 
(5) As of March 4, 1995, Rite Aid had $600,000,000 in revolving credit
    commitments for general corporate purposes consisting of a $250,000,000,
    364-day facility and a $350,000,000 five-year facility. Borrowings under
    these facilities bear interest rates, at Rite Aid's option, based on the
    prime federal funds, certificate of deposit or London interbank rates, as
    well as competitive bid. Pricing on loans and commitments will vary
 
                                       21
<PAGE>
    commensurate with credit quality. The 364-day facility has a 7/100% per
    annum facility fee on the entire commitment amount irrespective of usage.
    The five-year facility has a 1/10% per annum facility fee on the entire
    commitment amount. Both credit facilities also have a 1/20% per annum
    utilization fee on borrowing in excess of 50% of the facilities. As of March
    4, 1995, and February 26, 1994, there were no amounts outstanding under
    these agreements.
 
    Rite Aid maintains, at all times, unused long-term revolving credit
    agreement commitments at least equal to the principal amount of its
    outstanding commercial paper which Rite Aid intends to carry on a long-term
    basis. Accordingly, outstanding commercial paper of $350,000,000 as of
    March 4, 1995, and $156,000,000 as of February 26, 1994, was classified as
    long-term debt on the consolidated balance sheet. The remaining outstanding
    commercial paper of $86,500,000 at year-end 1995 and $30,000,000 at
    year-end 1994 was classified as short-term debt.
 
    In August 1993, Rite Aid issued 6 7/8% senior debentures having an
    aggregate principal amount of $200,000,000. These debentures are due August
    15, 2013, and may not be redeemed prior to maturity or be entitled to any
    sinking fund. The net proceeds from this issuance were used for working
    capital and general corporate purposes, including the repayment of
    outstanding commercial paper of Rite Aid.
 
    Rite Aid's 6 3/4% zero coupon subordinated convertible notes due on July
    24, 2006, are convertible at any time by the holder into Rite Aid Common
    Stock at a rate of 15.993 shares per note. The conversion rate will not be
    adjusted for accrued original issue discount. Any note will be purchased by
    Rite Aid, at the option of the holder, on July 24, 1996, and July 24, 2001,
    for a purchase price per note of $514.86 and $717.54, respectively,
    representing the issue price plus accrued original issue discount to each
    such date. Rite Aid may redeem the notes for cash at any time, in whole or
    in part, at redemption prices equal to the issue price plus accrued

    original issue discount to the date of redemption.
 
    In accordance with the terms of the merger agreement with Perry Drug
    Stores, Inc. ('Perry'), Perry's 8 1/2% convertible debentures were redeemed
    on March 15, 1995, through the use of proceeds from additional commercial
    paper borrowings.
 
    The aggregate annual principal payments as of March 4, 1995 of long-term
    debt for the five succeeding fiscal years are as follows: 1996,
    $51,053,000; 1997, $607,000; 1998, $862,000; 1999, $4,139,000; and 2000,
    $435,000.
 
    Rite Aid has complied with restrictions and limitations included in the
    provisions of various loan and credit agreements. As of March 4, 1995,
    retained earnings were not restricted as to payment of dividends by these
    provisions.
 
(6) As part of Rite Aid's restructuring in fiscal year 1994, the Rite Aid Board
    authorized a 'Dutch Auction' cash self-tender offer for up to 22,000,000
    shares of its common stock. The tender offer commenced on January 10, 1994,
    and expired on February 7, 1994, at tender prices ranging from $16.00 per
    share to $18.50 per share. A total of 2,077,271 shares were acquired by Rite
    Aid at $18.50 per share.
 
    On February 16, 1994, the Rite Aid Board approved a stock repurchase
    program to acquire up to 5,000,000 shares of Rite Aid's Common Stock in the
    open market or in privately negotiated transactions. During fiscal year
    1995, 1,847,798 shares were purchased in connection with this repurchase
    program. During fiscal year 1996, an additional 407,100 shares of Rite Aid
    Common Stock have been repurchased.

      (collectively, the 'Revco Companies'). The Chapter 11 cases of the Revco Companies were commenced on July 28,
      1988 (the 'Petition Date'). The Revco Companies' financial difficulties, and the reasons for the Chapter 11
      filings, were principally attributable to their inability to meet interest payments, dividends and retirement
      provisions on debt and equity incurred to finance a 1986 leveraged buyout.

                                  INTRODUCTION
 
   
     This Proxy Statement ('Proxy Statement') is being furnished to the holders
of common stock, par value $1.00 per share ('Rite Aid Common Stock'), of Rite

Aid Corporation, a Delaware corporation ('Rite Aid'), in connection with the
solicitation of proxies by the Board of Directors of Rite Aid (the 'Rite Aid
Board') for use at a Special Meeting of Stockholders of Rite Aid to be held at
the Radisson Hotel, 1150 Camp Hill Bypass, Camp Hill, Pennsylvania on Thursday,
March 28, 1996, at 10:00 a.m., local time, and at any and all adjournments or
postponements thereof (the 'Rite Aid Special Meeting') for purposes described
herein.
    
 
     This Proxy Statement relates to the Agreement and Plan of Merger, dated as
of November 29, 1995 (the 'Merger Agreement'), among Rite Aid, Ocean Acquisition
Corporation, a Delaware corporation and a wholly owned subsidiary of Rite Aid
('Sub'), and Revco D.S., Inc., a Delaware corporation ('Revco'), which provides
for the merger (the 'Merger') of Sub with and into Revco, with Revco surviving
as a wholly owned subsidiary of Rite Aid. Subject to the terms and conditions of
the Merger Agreement, if the Merger is consummated, each share of common stock,
par value $.01 per share, of Revco ('Revco Common Stock') issued and outstanding
immediately prior to the effective time of the Merger (other than shares of
Revco Common Stock owned by Revco as treasury stock and other than shares of
Revco Common Stock owned by Rite Aid and Sub and other than shares of Revco
Common Stock held by holders who have properly exercised and perfected any
appraisal rights ('Dissenting Revco Shares') under the Delaware General
Corporation Law (the 'DGCL')) shall by virtue of the Merger and without any
action on the part of the holder thereof be converted into either (x) the right
to receive a number of duly authorized, validly issued, fully paid and
nonassessable shares of Rite Aid Common Stock determined as set forth below (the
'Exchange Ratio'); provided that Rite Aid will not issue more than 1.125 nor
fewer than .91666 shares of Rite Aid Common Stock per share of Revco Common
Stock or (y) if the Alternative Consideration (as defined below) is applicable,
then the right to receive the Alternative Consideration, plus, in each of clause
(x) and (y) above, any Additional Consideration (as defined herein). Each share
of Rite Aid Common Stock will be issued with one associated preferred stock
purchase right (a 'Right') in accordance with the Shareholder Rights Agreement,
dated as of April 5, 1989, between Rite Aid and Harris Trust Company of New York
(the 'Rite Aid Rights Agreement').
 
   
     The per share value of Rite Aid Common Stock which stockholders of Revco
will receive in the Merger will be determined during a randomly selected
fifteen-day pricing period (the 'Pricing Period') during the forty trading days
ending five days before the Revco Special Meeting to consider the Merger.
PROMPTLY FOLLOWING THE CLOSE OF THE PRICING PERIOD, RITE AID AND REVCO WILL
ISSUE A JOINT PRESS RELEASE ANNOUNCING THE EXCHANGE RATIO. IF THERE IS TO BE ANY
CASH ADJUSTMENT AMOUNT (AS DESCRIBED HEREIN), SUCH PRESS RELEASE WILL ALSO
DISCLOSE THAT AMOUNT. ONCE THE PRICING PERIOD HAS ENDED, STOCKHOLDERS MAY ALSO
CALL MACKENZIE PARTNERS, INC. TOLL FREE AT 1-800-322-2855 OR COLLECT AT (212)
929-5500 TO LEARN THE EXCHANGE RATIO AND THE CASH ADJUSTMENT AMOUNT, IF ANY.
    
 
     In the Merger, stockholders of Revco will receive one share of Rite Aid
Common Stock if the average value per share of Rite Aid Common Stock during the
Pricing Period is $27.50. If the average per share value of Rite Aid Common
Stock determined during the Pricing Period is greater than $27.50, stockholders
of Revco will receive, for each share of Revco Common Stock, that amount of Rite

Aid Common Stock having a value so determined of $27.50 plus 50% of such
increase in market value of Rite Aid Common Stock over $27.50, provided that in
no event will Rite Aid issue less than .91666 shares of Rite Aid Common Stock
for each share of Revco Common Stock. Similarly, if the average per share value
of Rite Aid Common Stock determined during the Pricing Period is less than
$27.50, stockholders of Revco will receive, for each share of Revco Common
Stock, that amount of Rite Aid Common Stock having a value so determined of
$27.50 less 50% of such decrease in market value of Rite Aid Common Stock below
$27.50, provided that in no event will Rite Aid issue more than 1.125 shares of
Rite Aid Common Stock for each share of Revco Common Stock. Alternatively, if
the average per share value of the Rite Aid Common Stock determined during the
Pricing Period is less than $27.50, Rite Aid will have the option of delivering,
for each share of Revco Common Stock, one share of Rite Aid Common Stock plus
cash (the 'Cash Adjustment Amount') in an amount equal to 50% of such decrease
in market value of Rite Aid Common Stock below $27.50, provided that in no event
will more than $2.75 per share of Revco Common Stock be paid in cash.
 
                                       25
<PAGE>
     The DGCL does not require the Rite Aid Board to submit the Merger Agreement
to a vote of the Rite Aid stockholders. Accordingly, the stockholders of Rite
Aid are not being asked to consider and vote upon the adoption and approval of
the Merger Agreement at the Rite Aid Special Meeting. At the Rite Aid Special
Meeting, the stockholders of Rite Aid will consider and vote upon the Share
Issuance as required by a rule of the New York Stock Exchange. Pursuant to such
New York Stock Exchange rule, a company may not issue 20% or more of the
company's outstanding shares without a vote of the company's stockholders.
 
     The Rite Aid Board has determined that the Merger is advisable, fair to and
in the best interests of the stockholders of Rite Aid and determined to proceed
with the Merger even if the Share Issuance is not approved by the Rite Aid
stockholders. Therefore, in the event that the Rite Aid stockholders do not
approve the Share Issuance but all conditions to the Merger are otherwise
satisfied or waived (if permissible), the Alternative Consideration contemplated
by the Merger Agreement will be paid to Revco's stockholders upon consummation
of the Merger and approximately 19.9% of Rite Aid's current issued and
outstanding shares will be issued in the Merger.
 
     In the event that at the Rite Aid Special Meeting the stockholders of Rite
Aid do not approve the issuance of Rite Aid Common Stock pursuant to the Merger
Agreement (the 'Share Issuance'), but all conditions to the Merger are otherwise
satisfied or waived (if permissible), Revco, Rite Aid and Sub will nonetheless
consummate the Merger and shares of Revco Common Stock issued and outstanding
immediately prior to the Effective Time (other than shares of Revco Common Stock
owned by Revco as treasury stock and other than shares of Revco Common Stock
owned by Rite Aid and Sub and other than Dissenting Revco Shares) will, at the
effective time of the Merger, be converted into the right to receive a
combination of (x) shares of Rite Aid Common Stock which will represent in the
aggregate 19.9% of the then outstanding shares of Rite Aid Common Stock (which
will be determined in a manner consistent with the determination of the Exchange
Ratio) and (y) cash based on a pro rata portion of $27.50 (collectively, the
'Alternative Consideration'). The Merger Agreement provides that in the event
the Merger is not consummated prior to certain dates, holders of shares of Revco
Common Stock will be entitled to receive interest on the consideration payable

to them in the Merger at rates set forth in the Merger Agreement. See 'MERGER
AGREEMENT--Conversion of Revco Common Stock.'
 
   
     This Proxy Statement and the accompanying form of proxy are first being
mailed to stockholders of Rite Aid on or about February 20, 1996.
    
 
                            RITE AID SPECIAL MEETING
 
PURPOSE
 
     At the Rite Aid Special Meeting, the stockholders of Rite Aid will consider
and vote upon a proposal to approve the issuance of up to a maximum of
42,865,712 shares of Rite Aid Common Stock pursuant to the Merger (the 'Share
Issuance').
 
     The Rite Aid Board has unanimously determined that the Merger is advisable
and fair to and in the best interests of the stockholders of Rite Aid and has
approved the Merger Agreement. THE RITE AID BOARD HAS UNANIMOUSLY APPROVED THE
MERGER AGREEMENT AND RECOMMENDS THAT THE STOCKHOLDERS OF RITE AID VOTE IN FAVOR
OF THE SHARE ISSUANCE AT THE RITE AID SPECIAL MEETING. See 'THE MERGER--Rite
Aid's Reasons for the Merger; Recommendation of the Rite Aid Board.'
 
     Representatives of Rite Aid's principal accountants are not expected to be
present at the Rite Aid Special Meeting.
 
RECORD DATE; VOTING RIGHTS
 
   
     Only holders of record of Rite Aid Common Stock at the close of business on
February 12, 1996 (the 'Rite Aid Record Date') are entitled to receive notice of
and to vote at the Rite Aid Special Meeting. At the close of business on the
Rite Aid Record Date, there were 83,829,330 shares of Rite Aid Common Stock
outstanding, each of which entitles the registered holder thereof to one vote.
    
 
                                       26
<PAGE>
SHARE OWNERSHIP OF MANAGEMENT
 
   
     At the close of business on the Rite Aid Record Date, directors and
executive officers of Rite Aid and their affiliates were the beneficial owners
of an aggregate of approximately 3,425,439 (approximately 4.1%) of the shares of
Rite Aid Common Stock then outstanding.
    
 
QUORUM
 
     The holders of a majority of the shares of Rite Aid Common Stock
outstanding and entitled to vote must be present in person or represented by
proxy at the Rite Aid Special Meeting in order for a quorum to be present.
 

     Shares of Rite Aid Common Stock represented by proxies which are marked
'abstain' will be counted as shares present for purposes of determining the
presence of a quorum on all matters, as will shares that are represented by
proxies that are executed by any broker, fiduciary or other nominee on behalf of
the beneficial owner(s) thereof regardless of whether authority to vote is
withheld by such broker, fiduciary or nominee on one or more matters.
 
     In the event that a quorum is not present at the Rite Aid Special Meeting,
it is expected that such meeting will be adjourned or postponed to solicit
additional proxies.
 
PROXIES
 
     All shares of Rite Aid Common Stock represented by properly executed
proxies in the enclosed form which are received in time for the Rite Aid Special
Meeting and have not been revoked will be voted in accordance with the
instructions indicated in such proxies. IF A PROXY IS SUBMITTED BUT NO
DIRECTIONS ARE GIVEN THEREIN, SHARES OF RITE AID COMMON STOCK REPRESENTED BY THE
PROXY WILL BE VOTED FOR THE SHARE ISSUANCE. Abstentions will have the effect of
a vote cast against the Share Issuance. Broker non-votes will be disregarded and
will have no effect on the vote. In addition, the persons designated in such
proxy will have discretion to vote upon any procedural matter relating to the
Rite Aid Special Meeting, including the right to vote for any adjournment or
postponement thereof proposed by the Rite Aid Board, including a postponement
and adjournment, to solicit additional proxies. Any proxy in the enclosed form
may be revoked by the stockholder executing it at any time prior to its exercise
by giving written notice thereof to the Secretary of Rite Aid, by signing and
returning a later dated proxy or by voting in person at the Rite Aid Special
Meeting. Attendance at the Rite Aid Special Meeting will not in and of itself
constitute the revocation of a proxy.
 
SOLICITATION OF PROXIES
 
     Proxies are being solicited hereby on behalf of the Rite Aid Board. In
addition to the use of the mail, solicitation may be made in person or by
telephone or otherwise by directors, officers and regular employees of Rite Aid.
Such directors, officers and regular employees will not be additionally
compensated for such solicitation, but may be reimbursed for out-of-pocket
expenses incurred in connection therewith. If undertaken, the expense of such
solicitation would be nominal. Rite Aid has retained MacKenzie Partners, Inc.
('MacKenzie') to aid in the solicitation of proxies from its stockholders.
MacKenzie will receive reasonable and customary compensation for its services
and will be reimbursed for certain reasonable out-of-pocket expenses.
 
REQUIRED VOTE
 
     Approval of the Share Issuance will require the affirmative vote of a
majority of the votes cast on the Share Issuance, provided that the total number
of votes cast on such proposal represents more than 50% of the outstanding
shares of Rite Aid Common Stock entitled to vote thereon at the Rite Aid Special
Meeting.

                             REVCO SPECIAL MEETING
 
     A Special Meeting of Stockholders of Revco (the 'Revco Special Meeting')
will be held as soon as practicable following the Rite Aid Special Meeting. At
the Revco Special Meeting, the stockholders of Revco will consider and vote upon
a proposal to approve and adopt the Merger Agreement. Following the consummation
of the Offer (as defined herein), because Rite Aid will own in excess of 50% of
the outstanding shares of Revco Common Stock, the affirmative vote of a majority
of Revco stockholders in favor of the approval and adoption of the Merger
Agreement will be assured. The stockholders of Revco will also consider and take
action upon any other business which may properly be brought before the Revco
Special Meeting.
 
     PRIOR TO THE EXECUTION OF THE MERGER AGREEMENT, THE BOARD OF DIRECTORS OF
REVCO (THE 'REVCO BOARD') UNANIMOUSLY DETERMINED (WITH ONE DIRECTOR ABSENT AND
TWO DIRECTORS ABSTAINING) THAT THE MERGER IS FAIR TO, AND IN THE BEST INTERESTS
OF, THE STOCKHOLDERS OF REVCO, APPROVED THE MERGER AGREEMENT, AND RECOMMENDED
THAT THE STOCKHOLDERS OF REVCO VOTE IN FAVOR OF THE APPROVAL AND ADOPTION OF THE
MERGER AGREEMENT AT THE REVCO SPECIAL MEETING. See 'THE MERGER--Revco's Reasons
for the Merger; Recommendation of the Revco Board.' For a discussion of the
interests that certain executive officers of Revco have with respect to the
Merger in addition to their interests as stockholders of Revco generally and
information regarding the treatment of options to purchase Revco Common Stock
and other rights of certain members of the Revco Board, see 'THE
MERGER--Interests of Certain Persons.' Such interests, together with other
relevant factors, were considered by the Revco Board in making its
recommendation and approving the Merger Agreement.

                                   THE MERGER
 
     The description of the Merger and the Merger Agreement contained in this
Proxy Statement does not purport to be complete and is qualified in its entirety
by reference to the Merger Agreement, a conformed copy of which is attached
hereto as Annex A and incorporated herein by reference.
 
GENERAL
 
   
     On December 4, 1995, Sub offered to purchase (the 'Offer') 35,144,833
shares of Revco Common Stock validly tendered according to the terms of the
Offer (representing approximately 50.1% of Revco's outstanding shares of common
stock on a fully diluted basis). On December 11, 1995, Rite Aid and Revco filed
notifications and report forms under the Hart-Scott-Rodino Antitrust
Improvements Act of 1976, as amended (the 'HSR Act') with the Federal Trade
Commission (the 'FTC') and the Antitrust Division of the United States
Department of Justice (the 'Antitrust Division'). On December 27, 1995, Rite Aid
and Revco received a request for additional information (the 'Second Request')
from the FTC. On January 4, 1996, Sub extended the Offer in order to comply with
the Second Request. On February 7, 1996, Rite Aid submitted its responses to the
Second Request with the FTC and believes that it is in substantial compliance
with the Second Request. Under applicable regulations, the Offer may not be
consummated until ten days after Rite Aid has substantially complied with the
Second Request or such later date as Rite Aid may agree to. Rite Aid has
voluntarily agreed with the FTC to extend such ten day waiting period through
Friday, February 23, 1996. The Offer is presently scheduled to expire on
February 23, 1996 and Rite Aid reserves the right to extend the Offer until the
expiration of the waiting period under the HSR Act.
    
 
     At the effective time of the Merger, each share of Revco Common Stock
issued and outstanding immediately prior to the Effective Time (other than
shares of Revco Common Stock owned by Revco as treasury stock and shares of
Revco Common Stock owned by Rite Aid, Sub or any other direct or indirect wholly
owned subsidiary of Rite Aid and other than Dissenting Revco Shares), shall by
virtue of the Merger and without any action on the part of the holder thereof be
converted into either (x) the right to receive a number of duly authorized,
validly issued, fully paid and nonassessable shares of Rite Aid Common Stock,
determined as set forth below (the 'Exchange Ratio'); provided that Rite Aid
shall not issue more than 1.125 or fewer than .91666 shares of Rite Aid Common
Stock per share of Revco Common Stock or (y) if the Alternative Consideration
(as defined below) is applicable, then the right to receive the Alternative
Consideration, plus, in each of clause (x) and (y) above, any Additional
Consideration (as defined below). Each share of Rite Aid Common Stock will be
issued with one associated Right.
 
   
     The per share value of the Rite Aid Common Stock which stockholders of
Revco would receive in the Merger will be determined during a randomly selected
fifteen-day pricing period (the 'Pricing Period') during the forty trading days
ending five days before the Revco Special Meeting to consider the Merger.
PROMPTLY FOLLOWING THE CLOSE OF THE PRICING PERIOD, RITE AID AND REVCO WILL

ISSUE A JOINT PRESS RELEASE ANNOUNCING THE EXCHANGE RATIO. IF THERE IS TO BE ANY
CASH ADJUSTMENT AMOUNT (AS DESCRIBED HEREIN), SUCH PRESS RELEASE WILL ALSO
DISCLOSE THAT AMOUNT. ONCE THE PRICING PERIOD HAS ENDED, STOCKHOLDERS MAY ALSO
CALL MACKENZIE PARTNERS, INC. TOLL FREE AT 1-800-322-2855 OR COLLECT AT (212)
929-5500 TO LEARN THE EXCHANGE RATIO AND THE CASH ADJUSTMENT AMOUNT, IF ANY.
    
 
     In the Merger, stockholders of Revco will receive one share of Rite Aid
Common Stock if the average per share value of Rite Aid Common Stock during the
Pricing Period is $27.50. If the average per share value of Rite Aid Common
Stock determined during the Pricing Period is greater than $27.50, stockholders
of Revco will receive, for each share of Revco Common Stock, that amount of Rite
Aid Common Stock having a value so determined of $27.50 plus 50% of such
increase in market value of Rite Aid Common Stock over $27.50, provided that in
no event will Rite Aid issue fewer than .91666 shares of Rite Aid Common Stock
for each share of Revco Common Stock. Similarly, if the average per share value
of Rite Aid Common Stock determined during the Pricing Period is less than
$27.50, stockholders of Revco will receive, for each share of Revco Common
Stock, that amount of Rite Aid Common Stock having a value so determined of
$27.50 less 50% of such decrease in market value of Rite Aid Common Stock below
$27.50, provided that in no event will Rite Aid issue more than 1.125 shares of
Rite Aid Common Stock for each share of Revco Common Stock. Alternatively, if
the average per share value of the Rite Aid Common Stock determined during the
Pricing Period is less than $27.50,
 
                                       29
<PAGE>
Rite Aid will have the option of delivering, for each share of Revco Common
Stock, one share of Rite Aid Common Stock plus cash in an amount equal to 50% of
such decrease in market value of Rite Aid Common Stock below $27.50, provided
that in no event will more than $2.75 per share of Revco Common Stock be paid in
cash.
 
     In the event that at the Rite Aid Special Meeting the stockholders of Rite
Aid do not approve the issuance of Rite Aid Common Stock pursuant to the Merger
Agreement, but all conditions to the Merger are otherwise satisfied or waived
(if permissible), Revco, Rite Aid and Sub will nonetheless consummate the Merger
and shares of Revco Common Stock issued and outstanding immediately prior to the
Effective Time (other than shares of Revco Common Stock owned by Revco as
treasury stock and other than shares of Revco Common Stock owned by Rite Aid and
Sub and other than Dissenting Revco Shares) will, at the Effective Time, be
converted into the right to receive a combination of (x) shares of Rite Aid
Common Stock which will represent in the aggregate 19.9% of the then outstanding
shares of Rite Aid Common Stock (which will be determined in a manner consistent
with the determination of the Exchange Ratio) and (y) cash based on a pro rata
portion of $27.50 (the 'Alternative Consideration').
 
     In the event the Merger is not consummated prior to April 29, 1996, and
Revco has not materially breached the Merger Agreement (other than by acts
caused or permitted by Rite Aid), then the stockholders of Revco will be
entitled to receive interest on the amount of the consideration that they
receive pursuant to the immediately preceding two paragraphs (such consideration
and interest thereon being referred to herein as the 'Merger Consideration'),
from April 29, 1996 until the earlier of the Effective Time or June 30, 1996,

calculated at an annual rate equal to the prime rate of interest (as announced
from time to time by Morgan Guaranty Trust Company of New York). In the event
Rite Aid and/or Sub, in violation of their obligations under the Merger
Agreement, fail or refuse to consummate the Merger on or prior to June 30, 1996
and Revco has not materially breached the Merger Agreement (other than by acts
caused or permitted by Rite Aid), then, in addition to any rights or remedies
that Revco and its stockholders otherwise have in law or at equity as a result
thereof, the stockholders of Revco will be entitled to receive interest from
June 30, 1996 on the amount of the Merger Consideration not paid until such
Merger Consideration is paid, calculated at the annual rate of the higher of (i)
the prime rate of interest (as announced from time to time by Morgan Guaranty
Trust Company of New York) plus 300 basis points or (ii) the amount otherwise
permitted by law. Any additional consideration paid or payable pursuant to this
paragraph is referred to herein as 'Additional Consideration.'
 
     THE MARKET VALUE OF THE RITE AID COMMON STOCK DURING THE PRICING PERIOD AND
AFTER THE EFFECTIVE TIME WILL, AMONG OTHER THINGS, DEPEND UPON, AND IS EXPECTED
TO FLUCTUATE WITH, THE PERFORMANCE OF RITE AID, CONDITIONS (ECONOMIC OR
OTHERWISE) AFFECTING THE RETAIL DRUGSTORE INDUSTRY, AND MARKET CONDITIONS AND
OTHER FACTORS THAT GENERALLY INFLUENCE PRICES OF SECURITIES.
 
BACKGROUND OF THE MERGER
 
     The Revco Board and senior management of Revco regularly review the current
and future state of Revco's strategic position and short-term and long-term
prospects. In the ordinary course of Rite Aid's long-term strategic review
process, Rite Aid routinely analyzes potential acquisitions of various retail
drugstore chains. On August 17, 1995, Mr. Martin Grass, Chairman and Chief
Executive Officer of Rite Aid, spoke by telephone with Mr. David Schulte, a
general partner of the general partner of the Stockholder and a member of the
Revco Board. In the conversation, Mr. Grass told Mr. Schulte that Rite Aid was
possibly interested in purchasing Revco in a merger transaction involving a
combination of cash and stock. Mr. Schulte told Mr. Grass that he would contact
Mr. Dwayne Hoven, President and Chief Executive Officer of Revco, to ask him to
send Mr. Grass a Confidentiality Agreement. After execution of the
Confidentiality Agreement, Revco provided certain due diligence information
requested by Rite Aid.
 
     On August 28, 1995, Mr. Grass, Mr. Franklin Brown, Executive Vice President
and Chief Legal Counsel of Rite Aid, and Mr. Frank Bergonzi, Executive Vice
President and Chief Financial Officer of Rite Aid, met in Chicago with Mr.
Schulte, Ms. Sheli Rosenberg, a member of the Revco Board, Mr. Joel Friedland, a
general partner of Chilmark Partners, L.P., an affiliate of the Stockholder, Mr.
Hoven, and Mr. James Hagan, Executive
 
                                       30
<PAGE>
Vice President and Chief Financial Officer of Revco. A dinner meeting took place
and issues such as the possible price and synergies that would be created from a
merger were discussed. The parties ended the meeting without any definitive
conclusions about a future meeting.
 
     On September 21, 1995, Mr. Grass and Mr. Brown were in Cleveland, Ohio for
a meeting on another business matter with Mr. Hoven. After the meeting, Mr.

Grass met with Mr. Hoven for a brief period to discuss the possible acquisition
of Revco by Rite Aid. At the meeting, Mr. Grass advised Mr. Hoven that if an
acceptable price could be negotiated, Mr. Grass believed that the transaction
would create the opportunity to build a more successful company than if either
company continued on a stand-alone basis.
 
     On September 28, 1995, Mr. Grass spoke by telephone with Mr. Sam Zell, the
Co-Chairman of Revco, and discussed the terms and price range Mr. Grass would
offer for Revco.
 
     On October 6, 1995, Mr. Hoven spoke with Mr. Grass by telephone and
discussed questions that Mr. Grass had about the due diligence review Rite Aid
was conducting with respect to Revco.
 
     During the week of October 9, 1995, Mr. Rod Dammeyer, a member of the Revco
Board, called Mr. Grass and a meeting was arranged for October 31, 1995 in
Chicago. At the October 31, 1995 meeting, Mr. Grass and Mr. Brown met with Mr.
Dammeyer and Ms. Rosenberg and established a preliminary basis for continuing
discussions to seek to reach an agreement concerning a transaction, subject to
mutual due diligence, receipt of fairness opinions and Board approvals. Such
officers of Rite Aid and representatives of Revco and the Stockholder determined
to continue discussions on the basis of tentative terms as follows: Rite Aid
would acquire a majority of the outstanding shares of Revco Common Stock at
$27.50 per share of Revco Common Stock and the remaining shares of Revco Common
Stock would be acquired for shares of Rite Aid Common Stock based on a target
price of $27.50 for Rite Aid Common Stock subject to negotiating the terms of a
'collar' mechanism. In addition, the Stockholder would enter into a Stockholder
Agreement with Rite Aid in which it would agree to support the transaction. On
November 1, 1995, Mr. Grass and Mr. Brown held a telephone call with Mr.
Dammeyer, Ms. Rosenberg, Mr. Schulte and Mr. Friedland to discuss the collar. At
the end of the conversation, the parties had tentatively agreed upon the terms
of a 20% 'collar' mechanism which would provide that stockholders of Revco
participate in 50% of any increase or decrease in the market value of Rite Aid
Common Stock above or below $27.50 during an agreed upon pricing period.
 
     On November 3, 1995, counsel for Rite Aid distributed a draft Merger
Agreement and Stockholder Agreement to Revco and its legal and financial
advisors.
 
     On November 7, 1995, representatives of Rite Aid and its legal advisors met
with representatives of Revco and its legal advisors to commence negotiations
with respect to the terms of the proposed Merger Agreement and Stockholder
Agreement. Such negotiations continued throughout such week.
 
     On November 9, 1995, the Rite Aid Board held a meeting. At such meeting,
members of Rite Aid's senior management, Rite Aid's outside legal advisors and
Donaldson, Lufkin & Jenrette Securities Corporation ('DLJ') made presentations
to the Board regarding the proposed acquisition of Revco. The Rite Aid Board of
Directors analyzed and discussed the proposed Merger Agreement, Offer, Merger
and Stockholder Agreement and it was the consensus of Rite Aid's Board that
senior management of Rite Aid should continue with the negotiations relating to
the proposed transaction and report back to the Rite Aid Board once such
negotiations were completed.
 

     On November 10, 1995, the Human Resources Committee of the Revco Board held
a special meeting to discuss the need to provide for continuity of management in
light of the proposed transaction, including adequate change of control
mechanisms and severance benefit levels. After a detailed discussion, the Human
Resources Committee adopted the severance and compensation enhancement described
in 'THE MERGER--Interests of Certain Persons.'
 
     During the week of November 13, 1995, members of senior management of Rite
Aid and its legal advisors continued to negotiate the terms of the Merger
Agreement and Stockholder Agreement with representatives of Revco and the
Stockholder, including Mr. Dammeyer and Ms. Rosenberg, and their legal advisors.
During such negotiations, representatives of the Stockholder advised Rite Aid
that the Stockholder would be willing to agree
 
                                       31
<PAGE>
to tender its shares of Revco Common Stock in the Offer and vote for the Merger
but would not be willing to grant Rite Aid an option to purchase the
Stockholder's shares of Revco Common Stock.
 
     Rite Aid then insisted upon, and negotiated with Revco to obtain, an option
to purchase 19.9% of Revco's outstanding shares of Revco Common Stock at a price
of $27.50 per share of Revco Common Stock. Representatives of Revco advised Rite
Aid that they would be willing to recommend entering into such a Stock Option
Agreement subject to negotiation of satisfactory terms. The parties continued to
negotiate various modifications to the Merger Agreement, Stock Option Agreement
and Stockholder Agreement. Such negotiations continued through November 29,
1995.
 
     On November 28, 1995, the Rite Aid Board held a special meeting to review,
with the advice and assistance of the Board's financial and legal advisors, the
proposed Merger Agreement, the Stock Option Agreement, the Stockholder Agreement
and the transactions contemplated thereby, including the Offer and the Merger.
At such meeting, Rite Aid's management and legal advisors made presentations to
the Rite Aid Board concerning the transaction and DLJ provided its opinion to
the effect that the consideration to be paid by Rite Aid pursuant to the Merger
Agreement, taken as a whole, is fair to the stockholders of Rite Aid from a
financial point of view. The opinion of DLJ is attached hereto as Annex B.
Stockholders of Rite Aid are urged to read the full text of that opinion.
Following the Rite Aid Board's review of the transaction, the Rite Aid Board,
subject to the resolution of remaining open issues, unanimously authorized and
approved the proposed Merger Agreement, Stock Option Agreement, Stockholder
Agreement and the transactions contemplated thereby, and authorized the
execution and delivery of such Agreements.
 
     Also on November 28, 1995, the Revco Board held a special meeting to
review, with the advice and assistance of the Revco Board's financial and legal
advisors, the proposed Merger Agreement, Stock Option Agreement, Stockholder
Agreement and the transactions contemplated thereby, including the Offer and the
Merger. At such meeting, Revco's management and financial and legal advisors
discussed the transaction with the Revco Board and Morgan Stanley & Co.
Incorporated ('Morgan Stanley') provided its opinion to the effect that the
consideration to be received by the holders of shares of Revco Common Stock
pursuant to the Offer and the Merger, taken together, is fair from a financial

point of view to such holders. The opinion of Morgan Stanley is attached hereto
as Annex C. Stockholders of Revco are urged to read the full text of that
opinion. Following the Revco Board's review of the transaction, the Revco Board,
subject to the resolution of remaining open issues, unanimously (with one
director absent and two directors abstaining) approved the proposed Merger
Agreement, Stock Option Agreement and the transactions contemplated thereby,
authorized the execution and delivery of such Agreements, determined that the
Offer and the Merger are fair to and in the best interests of the holders of
shares of Revco Common Stock, recommended that stockholders of Revco who desire
to receive cash for their shares of Revco Common Stock accept the Offer and
tender their shares of Revco Common Stock pursuant to the Offer, and recommended
that stockholders of Revco approve and adopt the Merger Agreement. The Revco
Board's approval of the Merger Agreement, the Stock Option Agreement, the
Stockholder Agreement and the transactions contemplated thereby constituted
approval for purposes of Section 203 of the DGCL such that the provisions of the
statute are not applicable to such Agreements or the transactions contemplated
thereby.
 
     Negotiations between members of senior management of Rite Aid and its legal
advisors and representatives of Revco and their legal advisors to finalize the
remaining issues in the Merger Agreement continued through November 29, 1995. On
the evening of November 29, 1995, following the resolution of such open issues,
Rite Aid, the Sub and Revco executed and delivered the Merger Agreement and the
Stock Option Agreement; and Rite Aid, Sub and the Stockholder executed and
delivered the Stockholder Agreement.
 
     On November 30, 1995, Rite Aid and Revco issued the following joint press
release announcing the execution of the Merger Agreement, the Stockholder
Agreement and the Stock Option Agreement:

     FOR IMMEDIATE RELEASE
 
                RITE AID CORPORATION AND REVCO COMBINE TO CREATE
                        NATION'S LARGEST DRUGSTORE CHAIN
            MERGER CREATES COMPANY WITH OVER $11 BILLION IN REVENUES
               CASH TENDER SCHEDULED TO COMMENCE EARLY NEXT WEEK
 
                            ------------------------
 
          CAMP HILL, PA (November 30, 1995)--Rite Aid Corporation (RAD: NYSE,
     PSE) and Revco D.S., Inc. (RXR: NYSE) today announced that they have
     entered into a definitive merger agreement in which Rite Aid would acquire
     Revco. The merger creates the nation's largest drugstore chain with
     expected annualized revenues of over $11 billion and more than 4,500 stores
     in 22 states and the District of Columbia. The transaction is expected to
     be accretive to Rite Aid's earnings per share by the end of the first year
     of operations following the merger.
 
          Under the agreement, Rite Aid would purchase, in a first-step tender
     offer, at least 50.1% of the outstanding shares of Revco on a fully-diluted
     basis for $27.50 per share in cash and the remainder of the outstanding
     shares would be converted into Rite Aid stock in a second-step merger. As

     described below, the value of Rite Aid shares to be received for each Revco
     share in the second-step merger will increase to the extent the average
     value of Rite Aid stock is greater than $27.50 per share during a pricing
     period and will decrease if the average value of Rite Aid stock is less
     than $27.50 per share during such pricing period, but in no event will more
     than 1.125 shares or less than .91666 shares of Rite Aid stock be issued
     for each Revco share in the merger.
 
          The tender offer is not conditioned on obtaining financing. The total
     value of the merger is approximately $1.8 billion.
 
          The merger, which was approved by each company's Board of Directors,
     is expected to be completed in the first quarter of 1996. The tender offer
     is scheduled to commence early next week.
 
          Martin Grass, Chairman of the Board of Directors and Chief Executive
     Officer of Rite Aid, said, 'The combination of these two great companies
     will create the preeminent retail drugstore chain in the United States.
     This transaction will nearly double our revenues and number of stores. Our
     significant investment in technology and infrastructure coupled with our
     innovative management changes have prepared us to seize the competitive
     advantage this merger represents. We anticipate a quick and smooth
     integration of the two companies.
 
          'The merger will increase Rite Aid's competitive advantage in our
     prescription benefits management subsidiary, Eagle Managed Care,' Mr. Grass
     continued. 'The addition of Revco's mail order capacity, as well as the
     increased number of outlets available in the combined entity, complements
     and broadens Rite Aid's managed healthcare delivery system. This expanded
     capacity is important leverage in attracting new contracts to the company.
 
          'We will be the best-positioned retail drugstore chain in the country
     to compete with the three large vertically integrated pharmacy benefit
     managers owned by the major pharmaceutical manufacturers. This combination
     should allow Rite Aid to offer customers the most competitive pharmacy
     prescription prices and services.'
 
          D. Dwayne Hoven, President and Chief Executive Officer of Revco, said,
     'In an environment of consolidation, Revco's Board of Directors felt that
     this offer was fair and reasonable and in the best interest of our
     stockholders. This offer is the culmination of one of the most remarkable
     turnarounds in corporate history. We built a company with productive real
     estate, clean inventories and great people. Revco people should not lose
     sight of what they have accomplished.'
 
          Rite Aid expects to achieve synergies of $156 million through
     elimination of overlapping positions, streamlining distribution, reducing
     redundant advertising, and enhanced purchasing power. As in past Rite Aid
     mergers, Rite Aid will provide excellent severance packages, including
     out-placement counseling, to all affected personnel. Following completion
     of the merger, the Revco stores will operate under the Rite Aid banner. The
     headquarters of Rite Aid will remain in Camp Hill, Pennsylvania.
 
                                       33

          Rite Aid indicated that it plans to take a pre-tax charge to earnings
     of $163 million to cover the cost of integrating the two companies. Rite
     Aid anticipates that only a small percentage of the combined company's
     stores will be closed. A decision on which drugstores will be closed will
     occur after the merger is completed.
 
          The merger agreement provides for Ocean Acquisition Corporation, a
     subsidiary of Rite Aid, to make a cash tender offer for at least 50.1% of
     the outstanding shares of common stock of Revco on a fully diluted basis at
     a price of $27.50 per share. The tender offer will be followed by a
     second-step merger in which each share of Revco not acquired in the tender
     offer will be converted into the right to receive Rite Aid common stock
     and/or, under certain circumstances, cash.
 
          The per share value of Rite Aid common stock which stockholders of
     Revco would receive in the second-step merger will be determined during a
     randomly selected fifteen-day pricing period during the forty trading days
     ending five days before the meeting of stockholders of Revco to consider
     the merger. Stockholders of Revco would receive one share of Rite Aid
     common stock if the average market value of Rite Aid common stock during
     the pricing period is $27.50.
 
          If the average value of Rite Aid common stock is greater than $27.50
     during the selected fifteen-day pricing period, stockholders of Revco will
     receive, for each Revco share, Rite Aid common stock having a value of
     $27.50 plus 50% of the increase in market value of Rite Aid common stock
     over $27.50, provided that in no event would Rite Aid issue less than
     .91666 shares of Rite Aid common stock for each Revco share in the merger.
     Similarly, if the average value of Rite Aid common stock during the pricing
     period is less than $27.50, stockholders of Revco will receive, for each
     Revco share, Rite Aid common stock having a value of $27.50 less 50% of the
     decrease in market value of Rite Aid common stock below $27.50, provided
     that in no event would Rite Aid issue more than 1.125 shares of Rite Aid
     common stock.
 
          If the average value of Rite Aid common stock during the pricing
     period is less than $27.50, Rite Aid would have the option of delivering,
     for each Revco share, one share of Rite Aid common stock plus cash in an
     amount equal to 50% of the decrease in market value of Rite Aid common
     stock below $27.50, provided that in no event would more than $2.75 per
     Revco share be paid in cash.
 
          In the event that the stockholders of Rite Aid do not approve the
     issuance of Rite Aid common stock pursuant to the merger, but all
     conditions to the merger are otherwise satisfied or waived, each Revco
     share would be converted into the right to receive a combination of cash
     and shares of Rite Aid common stock (determined based on the formulas
     described above) representing in the aggregate 19.9% of Rite Aid's
     outstanding shares.
 
          Rite Aid also stated that it has entered into a stockholder agreement
     with Zell/Chilmark Fund L.P., the major stockholder of Revco, pursuant to
     which Zell/Chilmark has agreed to tender its Revco shares (representing

     approximately 19.7 % of Revco's outstanding shares) into Rite Aid's tender
     offer and to vote in favor of the merger. Revco has granted Rite Aid an
     option to purchase 19.9% of Revco's shares under certain circumstances at
     $27.50 per share.
 
          The tender offer is conditioned on, among other things, the valid
     tender of 50.1% of the outstanding Revco shares on a fully diluted basis
     and the expiration or termination of any applicable waiting period under
     the Hart-Scott-Rodino Antitrust Improvements Act of 1976.
 
          Donaldson, Lufkin & Jenrette Securities Corporation provided a
     fairness opinion for Rite Aid. Morgan Stanley & Co. Incorporated provided a
     fairness opinion for Revco.
 
          Revco D.S., Inc., based in Twinsburg, Ohio, operates over 2,100 stores
     in 14 Midwestern, Southeastern and Eastern states and has annual sales of
     approximately $4.4 billion.
 
          Rite Aid Corporation, based in Camp Hill, Pennsylvania, is the
     nation's largest drugstore chain, with over 2,700 stores in 21 states and
     the District of Columbia.
 
          General information about Rite Aid including corporate background and
     press releases is available, free of charge, through the company's
     News-On-Demand fax service at 800-916-7788.
 
   
     Sub commenced the Offer on December 4, 1995. On December 27, 1995, Rite Aid
received the Second Request from the FTC. On January 4, 1996, Sub extended the
Offer in order to comply with the Second Request. The Offer is presently
scheduled to expire on February 23, 1996 and Rite Aid reserves the right to
extend the Offer until the expiration of the waiting period under the HSR Act.

RITE AID'S REASONS FOR THE MERGER; RECOMMENDATION OF THE RITE AID BOARD
 
     The Rite Aid Board has unanimously determined that the Merger is advisable
and fair to and in the best interests of the stockholders of Rite Aid and has
approved the Merger Agreement. Accordingly, the Rite Aid Board recommends that
the stockholders of Rite Aid vote to approve the Share Issuance.
 
     For the foregoing reasons, the Rite Aid Board believes that the terms and
conditions of the Merger Agreement are in the best interests of Rite Aid and its
stockholders. In reaching its conclusion, the Rite Aid Board considered, among
other things:
 
          1. the judgment, advice and analyses of Rite Aid's management;
 
          2. the analyses prepared by DLJ and the oral opinion of DLJ presented
     to the Rite Aid Board on November 28, 1995 and confirmed in writing on
     November 29, 1995, to the effect that the consideration to be paid by Rite

     Aid pursuant to the Merger Agreement, taken as a whole, is fair to the
     stockholders of Rite Aid from a financial point of view. A copy of the
     written opinion dated November 29, 1995 of DLJ, setting forth the
     assumptions made, factors considered and scope of the review undertaken by
     DLJ, is attached as Annex B hereto and is incorporated herein by reference.
     RITE AID STOCKHOLDERS ARE URGED TO READ THE OPINION OF DLJ CAREFULLY AND IN
     ITS ENTIRETY. See 'THE MERGER--Opinion of DLJ'; 'THE MERGER--Background of
     the Merger;'
 
          3. the financial condition, results of operations and cash flows of
     Rite Aid and Revco, both on a historical and a prospective basis;
 
          4. the fact that the Merger is expected to be accretive to Rite Aid's
     earnings per share by the end of the first year of operations following the
     Merger;
 
          5. Rite Aid management's estimate, based on a preliminary review of
     Revco's business and operations, that the Merger will result in
     approximately $156 million of quantifiable annual cost savings, including
     the improvement in gross margins through enhanced purchasing power, closure
     of Revco's corporate headquarters and overlapping distribution facilities,
     elimination of duplicative overhead, elimination of redundant advertising
     expenditures, the consolidation of data centers and improved communications
     systems and a working capital benefit from the consolidation of warehouse
     inventories. See 'THE MERGER--Estimated Synergies;'
 
          6. the terms and conditions of the Merger Agreement, including the
     amount and form of Merger Consideration and the formulas and mechanisms
     which determine the Merger Consideration;
 
          7. historical market prices and trading information with respect to
     Rite Aid Common Stock and Revco Common Stock;
 
          8. the structure of the second-step Merger which provides for the
     Alternative Consideration in the event that the Rite Aid stockholders do
     not approve the Share Issuance, including the Additional Consideration
     which may be payable;
 
          9. the Stockholder's agreement to tender all of its shares of Revco
     Common Stock in the Offer and vote its shares of Revco Common Stock in
     favor of approval of the Merger and the Merger Agreement pursuant to the
     Stockholder Agreement; and
 
          10. the fact that as an inducement and a condition to entering into
     the Merger Agreement Revco agreed, pursuant to the Stock Option Agreement,
     to grant Rite Aid an irrevocable option to purchase up to 19.9% of Revco's
     issued and outstanding shares of Revco Common Stock at the time of exercise
     of such option.
 
     The foregoing discussion of the information and factors considered and
given weight by the Rite Aid Board is not intended to be exhaustive. The Rite
Aid Board did not assign relative weights to the factors or determine that any
factor was of particular importance. Rather, the Rite Aid Board viewed their
position and recommendation as being based on the totality of the information

presented to and considered by it.
 
     THE RITE AID BOARD UNANIMOUSLY RECOMMENDS THAT THE HOLDERS OF RITE AID
COMMON STOCK VOTE 'FOR' APPROVAL OF THE SHARE ISSUANCE.

OPINION OF DLJ
 
     Rite Aid engaged DLJ to render an opinion to the Rite Aid Board as to the
fairness of the Offer and the Merger, taken as a whole, to the stockholders of
Rite Aid from a financial point of view, to conduct such investigations as DLJ
deemed appropriate for such purposes, and to act as exclusive Dealer Manager for
Rite Aid in any tender or exchange offer for any debt or equity security
relating to the Offer and the Merger.
 
     On November 28, 1995, DLJ delivered its oral opinion, which was confirmed
by delivery of its written opinion dated November 29, 1995, to the effect that,
as of such date, the consideration to be paid by Rite Aid pursuant to the Offer
and the Merger (the 'Consideration'), taken as a whole, is fair to the
stockholders of Rite Aid from a financial point of view. THE FULL TEXT OF DLJ'S
WRITTEN OPINION IS SET FORTH AS ANNEX B TO THIS PROXY STATEMENT AND SHOULD BE
READ CAREFULLY IN ITS ENTIRETY, INCLUDING, WITHOUT LIMITATION, THE DESCRIPTIONS
OF THE PROCEDURES FOLLOWED, MATTERS CONSIDERED, ASSUMPTIONS MADE AND LIMITATIONS
OF THE REVIEW UNDERTAKEN IN ARRIVING AT SUCH OPINION. The opinion of DLJ
addresses the fairness of the Consideration, taken as a whole, to the
stockholders of Rite Aid from a financial point of view and does not constitute
a recommendation to any individual stockholder of Rite Aid or Revco as to how
such stockholder should vote at the Special Meeting.
 
     In rendering its opinion, DLJ, among other things: (i) analyzed certain
publicly available financial statements and other information of Rite Aid and
Revco; (ii) reviewed certain financial projections for Rite Aid, including
estimates of certain potential benefits of the proposed business combination,
prepared by the management of Rite Aid; (iii) reviewed certain financial
projections for Revco prepared by the management of Revco; (iv) discussed on a
limited basis the past and current operations and financial conditions and the
prospects of Rite Aid and Revco with senior executives of Rite Aid and Revco,
respectively; (v) reviewed the reported prices and trading activity for the Rite
Aid Common Stock and Revco Common Stock; (vi) reviewed publicly available
financial data and stock market performance data of other comparable public
retail drug store companies; (vii) reviewed the financial terms, to the extent
publicly available, of certain comparable acquisition transactions; (viii)
participated in discussions among representatives of Rite Aid, Revco and their
financial and legal advisors; (ix) reviewed the Merger Agreement and certain
related documents; and (x) performed such other analyses, inquiries and
investigations as it deemed appropriate.
 
     In addition, DLJ assumed and relied upon, without independent verification,
the accuracy and completeness of the information it reviewed for purposes of its
opinion. DLJ also assumed that the financial projections, including the
estimates of Rite Aid of certain potential benefits of the proposed business
combination, were reasonably prepared on bases reflecting the best currently
available estimates and judgments of the future financial performance of Rite

Aid and Revco, respectively. DLJ did not make an independent valuation or
appraisal of the assets or liabilities of Rite Aid or Revco, nor was it
furnished with any such appraisal. DLJ's opinion was necessarily based on
economic, market and other conditions as in effect on, and the information made
available to it as of, the date thereof. In arriving at its opinion, DLJ was not
authorized to solicit, and did not solicit, interest from any party with respect
to the acquisition of Revco or any of its assets nor did it consider the
prospect of alternate transactions involving Rite Aid.
 
     The following is a brief summary of the analyses performed by DLJ in
connection with DLJ's opinion to the Rite Aid Board. Such analyses are based on
a number of assumptions, including, among other things, the cost of integration,
estimated amounts and timing of the anticipated synergies, the projected
performance of Rite Aid and Revco, the projected performance of Rite Aid Common
Stock, prevailing interest rates and the final structure of the Offer and the
Merger.
 
     Rite Aid Common Stock Performance.  DLJ's analysis of Rite Aid's Common
Stock performance consisted of a historical analysis of closing prices and
trading volumes for the twelve months ended November 3, 1995 and of the S&P 400
relative to a comparable company index, which included Rite Aid, Revco,
Walgreen, Longs Drug Stores, Eckerd Corporation and Arbor Drugs from November 9,
1990 to November 3, 1995. In the twelve months ended November 3, 1995, the Rite
Aid Common Stock reached a high of $30.13 per share and a low of $21.63 per
share. On November 3, 1995, the closing price of Rite Aid Common Stock of $28.88
per share was at the high end of such range. Since September 1994, such
comparable company index has outperformed the S&P 400.

     Revco Common Stock Performance.  DLJ's analysis of Revco's Common Stock
performance consisted of a historical analysis of Revco's closing prices and
trading volumes for the twelve months ended November 3, 1995 and of the S&P 400
relative to a comparable company index, which included Rite Aid, Revco,
Walgreen, Longs Drug Stores, Eckerd Corporation and Arbor Drugs from November 9,
1990 to November 3, 1995. In the twelve months ended November 3, 1995, Revco
Common Stock reached a high of $25.38 per share and a low of $17.50 per share.
On November 3, 1995, the closing price of Revco Common Stock of $24.38 per share
was at the high end of such range. Since September 1994, such comparable company
index has outperformed the S&P 400.
 
     Pro Forma Accretion/Dilution Analysis.  DLJ analyzed the accretive/dilutive
impact of the Offer and the Merger, both excluding synergies and on a pro forma
basis for the estimated synergies, with respect to Rite Aid's twelve months
ended September 2, 1995 and estimated 1996 earnings per share ('EPS') and, both
excluding synergies and as such synergies are expected to be realized, with
respect to Rite Aid's projected 1997 and 1998 EPS. This analysis is based on a
number of assumptions, including, among other things, the cost of integration,
estimated amounts and timing of the synergies, the projected financial
performance of Rite Aid and Revco, the projected performance of Rite Aid Common
Stock, prevailing interest rates and the final structure of the Offer and the
Merger.
 
     Comparable Company Analysis.  Comparable company analysis ('Comparable

Company Analysis') examines a company's operating performance relative to a
group of publicly traded peers. Based on relative performance and outlook for a
company versus its peers, this analysis enables an implied unaffected market
trading value to be determined. DLJ analyzed the operating performance of Rite
Aid and Revco relative to four retail drug store companies deemed by DLJ to be
reasonably comparable to Rite Aid and Revco. These companies are as follows:
Walgreen, Longs Drug Stores, Eckerd Corporation and Arbor Drugs (these four
companies together with Rite Aid and Revco constitute the 'Comparable
Companies'). Historical financial information used in connection with the ratios
provided below with respect to the Comparable Companies is as of the most recent
financial statements publicly available for each company as of November 3, 1995.
 
     DLJ analyzed the relative performance and value for Rite Aid and Revco by
comparing certain market trading statistics for Rite Aid and Revco with the
Comparable Companies. DLJ examined certain publicly available financial data of
the Comparable Companies including enterprise value (defined as market value of
common equity plus book value of total debt and preferred stock less cash) as
multiples of latest twelve months revenues, earnings before interest taxes,
depreciation and amortization ('EBITDA') and earnings before interest and taxes
('EBIT') and price earnings ratios ('P/E') based on the latest twelve months EPS
and estimated 1995 and 1996 EPS. As of November 3, 1995, this analysis resulted
in (i) a range of 0.3x to 0.7x enterprise value to latest twelve months revenues
for the Comparable Companies compared to 0.5x for Revco at the assumed
Consideration price to be paid per share ($27.50) in the Offer and the Merger,
taken as a whole (the 'Consideration Price'), (ii) a range of 6.3x to 11.2x
enterprise value to latest twelve months EBITDA for the Comparable Companies
compared to 9.0x for Revco at the Consideration Price before synergies, (iii) a
range of 9.4x to 13.8x enterprise value to latest twelve months EBIT for the
Comparable Companies compared to 13.9x for Revco at the Consideration Price
before synergies, (iv) a range of 15.9x to 22.8x P/E based on latest twelve
months earnings for the Comparable Companies compared to 22.0x for Revco at the
Consideration Price before synergies and (v) a range of 14.5x to 21.3x and 13.2x
to 18.8x estimated P/E based on 1995 and 1996 estimates, respectively, for the
Comparable Companies, compared to 21.1x and 17.8x, respectively, for Revco at
the Consideration Price before synergies. EPS estimates for Rite Aid, Revco and
the Comparable Companies were based on estimates provided by the Institutional
Brokers Estimate System ('IBES').
 
     No company utilized in the Comparable Companies analysis as a comparison is
identical to Rite Aid or Revco. Accordingly, an analysis of the results of the
foregoing necessarily involves complex considerations and judgments concerning
differences in financial and operating, characteristics of Rite Aid and Revco
and other factors that could affect the public trading value of the Comparable
Companies or company to which they are being compared. Mathematical analysis
(such as determining the mean or median) is not in itself a meaningful method of
using comparable company data.
 
     Comparable Transaction Analysis.  DLJ performed an analysis of precedent
transactions involving retail drug store companies in order to obtain a
valuation range for Revco Common Stock based upon selected merger and
acquisition transactions in the retail drug store industry. Multiples of
aggregate purchase price (defined as the
 
                                       37

<PAGE>
equity value of the offer plus book value of total debt and preferred stock less
cash) to be paid by the stockholders of Rite Aid in the Offer and the Merger to
revenues, EBITDA and EBIT were compared with multiples paid in certain other
merger and acquisition transactions involving retail drug store companies from
January 1989 through March 1995. The comparison included a total of seven
transactions. These transactions included: Rite Aid and Perry Drug Stores, Inc.;
Revco and Hook-SupeRx, Inc.; PayLess Drug Stores and TPH Corp.; Zell/Chilmark,
et al. and Revco; THC Corp. and Thrifty Corp.; Melville Corp. and Peoples Drugs;
and Big B Inc. and Reed Drug Co. This analysis resulted in (i) a range of 0.3x
to 0.5x latest twelve months revenue compared to 0.5x for Revco at the
Consideration Price, (ii) a range of 7.4x to 8.9x latest twelve months EBITDA
compared to 9.0x for Revco at the Consideration Price before synergies and (iii)
a range of 12.1x to 18.7x latest twelve months EBIT compared to 13.9x for Revco
at the Consideration Price before synergies.
 
     No transaction utilized in the comparable transaction analysis is identical
to the Offer and the Merger. Accordingly, an analysis of the results of the
foregoing necessarily involves complex considerations and judgments concerning
differences in financial and operating characteristics of Rite Aid and Revco and
other factors that could affect the acquisition value of the companies to which
they are being compared. Mathematical analysis (such as determining the mean or
median) is not itself a meaningful method of using comparable transaction data.
 
     Premium Analysis.  DLJ performed a comparison of the premium represented by
the Consideration Price to premiums offered in acquisitions of $1.0 billion to
$3.0 billion in size ('Comparable Acquisitions') for the year to date ended
November 3, 1995 and to premiums offered in selected retail drug store company
merger and acquisition transactions ('Related Acquisitions') from April 1994 to
March 1995. DLJ found that of the 12 transactions surveyed, nine had a premium
of less than 50% to the market price one day prior to announcement, while four
had a premium of less than 40% to the market price one day prior to
announcement. The Consideration Price represented: a 7.8% premium to the trading
price one day prior to announcement, as compared to mean premiums for Comparable
and Related Acquisitions of 41.6% and 48.7%, respectively; a premium of 8.9% to
the trading price one week prior to the announcement, as compared to mean
premiums for Comparable and Related Acquisitions of 42.4% and 53.6%,
respectively; and a 15.8% premium to the trading price one month prior to the
announcement, as compared to mean premiums for Comparable and Related
Acquisitions of 50.4% and 63.1%, respectively.
 
     Discounted Cash Flow Analysis.  DLJ performed a discounted cash flow
analysis for the five-year period ending with the 2001 fiscal year on the
stand-alone unlevered free cash flows of Rite Aid and Revco, based upon
financial projections prepared by the respective managements of each company.
Unlevered free cash flows were calculated as the after-tax operating earnings of
Rite Aid and Revco, respectively, plus depreciation and amortization and other
non-cash items, plus (or minus) net changes in non-cash working capital, minus
projected capital expenditures. DLJ calculated terminal values by applying a
range of estimated EBITDA multiples to the projected unlevered free cash flows
of Rite Aid and Revco, respectively, in fiscal year 2001. The unlevered free
cash flows and terminal values were then discounted to the present using a range
of discount rates, representing an estimated range of the weighted average cost
of capital of Rite Aid and Revco. Based on this analysis, DLJ calculated per

share equity values of Rite Aid ranging from $29.07 to $42.14 and of Revco
ranging from $25.68 to $37.90.
 
     The preparation of a fairness opinion is a complex process and is not
necessarily susceptible to a partial analysis or summary description. DLJ
believes that its analyses must be considered as a whole and that selecting
portions of its analyses, without considering the entirety of the analyses,
would create an incomplete view of the process underlying its opinion. In
addition, DLJ may have given various analyses more or less weight than other
analyses, and may have deemed various assumptions more or less probable than
other assumptions, so that the ranges of valuations resulting for any particular
analysis described above should not be taken to be DLJ's view of the actual
value of Rite Aid and Revco.
 
     In performing its analyses, DLJ made numerous assumptions with respect to
industry performance, general business and economic conditions and other
matters, many of which are beyond the control of Rite Aid and Revco. The
analyses performed by DLJ are not necessarily indicative of actual values, which
may be significantly more or less favorable than suggested by such analyses.
Such analyses were prepared solely as a part of DLJ's analysis of the fairness
of the consideration to be paid by Rite Aid pursuant to the Merger Agreement to
 
                                       38
<PAGE>
the stockholders of Rite Aid and were reviewed with the Rite Aid Board in
connection with the delivery of DLJ's opinion. The analyses do not purport to be
appraisals or to reflect the prices at which Rite Aid or Revco might actually be
sold. Because such estimates are inherently subject to uncertainty, none of Rite
Aid, DLJ or any other person assumes responsibility for their accuracy. In
addition, as described above, DLJ's opinion and the information provided by it
to the Rite Aid Board were two of many factors taken into consideration by the
Rite Aid Board in making its determination to approve the Offer and the Merger.
Consequently, DLJ's methods of analysis described above should not be viewed as
determinative of the Rite Aid Board's or Rite Aid management's opinion with
respect to the value of Rite Aid or of whether the Rite Aid Board or Rite Aid
management would have been willing to agree to different consideration.
 
     DLJ provides a full range of financial, advisory and brokerage services and
in the course of its normal trading activities may from time to time effect
transactions and hold positions in the securities or options on securities of
Revco and/or Rite Aid for its own account and for the account of customers.
 
     DLJ was selected to render an opinion in connection with the Offer and the
Merger based upon DLJ's qualifications, expertise and reputation, including the
fact that DLJ, as part of its investment banking business, is continually
engaged in the valuation of businesses and their securities in connection with
mergers and acquisitions, negotiated underwritings, competitive bidding,
secondary distributions of listed and unlisted securities, private placements
and valuation for corporate and other purposes.
 
     Pursuant to Rite Aid's November 9, 1995 letter agreement, Rite Aid has
agreed, as compensation for DLJ's services as both renderer of an opinion to
Rite Aid in connection with its acquisition of Revco and exclusive Dealer
Manager in connection with the Offer, (i) to pay DLJ a fee of $1,550,000 (which

has been paid) at the time DLJ notifies the Rite Aid Board that it is prepared
to deliver an opinion as to the fairness of the Consideration, taken as a whole,
to the stockholders of Rite Aid from a financial point of view and (ii) upon the
request by DLJ from time to time, to reimburse DLJ promptly for all
out-of-pocket expenses (including the reasonable fees and expenses of counsel)
and to indemnify DLJ against certain liabilities and expenses in connection with
its engagement, including certain liabilities under the federal securities laws.
DLJ is entitled to the foregoing fees, expenses and indemnification as a result
of the delivery to the Rite Aid Board of its written opinion dated November 29,
1995 and the commencement of the Offer with respect to which DLJ acted as Dealer
Manager.
 
REVCO'S REASONS FOR THE MERGER; RECOMMENDATION OF THE REVCO BOARD
 
     At a special meeting held on November 28, 1995, the Revco Board (i)
determined that the Merger Agreement and the transactions contemplated thereby,
including, without limitation, the Offer, the Merger, the Stockholder Agreement,
the Stock Option Agreement and the transactions contemplated thereby, are fair
to, and in the best interest of, the stockholders of Revco, and (ii) approved
the Merger Agreement and the transactions contemplated thereby, including,
without limitation, the Offer and the Merger, and approved the Stockholder
Agreement, the Stock Option Agreement and the transactions contemplated thereby.
At such meeting, the Revco Board recommended that the holders of shares of Revco
Common Stock approve and adopt the Merger Agreement.
 
     In reaching its conclusion to approve the Merger Agreement and recommend
that holders of shares of Revco Common Stock approve and adopt the Merger
Agreement, the Revco Board considered a number of factors, including, without
limitation, the following:
 
          1. the terms and conditions of the Merger Agreement, including the
     amount and form of Merger Consideration;
 
          2. the fact that the value of the shares of Rite Aid Common Stock to
     be received for each share of Revco Common Stock in the Merger will
     increase to the extent the average value of Rite Aid Common Stock is
     greater than $27.50 per share during the Pricing Period and will decrease
     if the average value of Rite Aid Common Stock is less than $27.50 per share
     during the Pricing Period;
 
          3. presentations by management of Revco (at a board meeting held on
     November 28, 1995, and at previous board meetings) regarding the financial
     condition, results of operations, business and prospects of Revco,
     including the prospects of Revco if it remained independent;
 
                                       39
<PAGE>
          4. the fact that upon consummation of the Offer, Rite Aid and/or Sub
     will own at least 50.1% of the outstanding shares of Revco Common Stock and
     have agreed to vote in favor of the approval and adoption of the Merger
     Agreement, and, therefore, a vote in favor of the approval and adoption of
     the Merger Agreement would be assured without the vote of any other holder
     of shares of Revco Common Stock;
 

          5. the historical market prices for the shares of Revco Common Stock,
     particularly the fact that the $27.50 per share price in the Offer
     represented (x) a premium of approximately 6.8% over the closing price of
     $25.75 for the shares of Revco Common Stock on November 27, 1995, the last
     trading day prior to the approval of the Merger Agreement, and (y) a higher
     price than the shares of Revco Common Stock have ever traded;
 
          6. the expected future trading values of the shares of Revco Common
     Stock in light of, among other things, the historical trading multiples of
     other companies in Revco's line of business;
 
          7. the analyses prepared by Morgan Stanley and the oral opinion of
     Morgan Stanley presented to the Revco Board on November 28, 1995 and
     confirmed in writing on November 29, 1995 to the effect that, as of such
     date and based upon its review and analysis and subject to the limitations
     set forth therein, the consideration to be received by the holders of Revco
     Common Stock pursuant to the Offer and the Merger, taken together, is fair
     from a financial point of view to such holders. A copy of the written
     opinion, dated November 29, 1995, of Morgan Stanley, setting forth the
     assumptions made, factors considered and scope of the review undertaken by
     Morgan Stanley, is attached as Annex C hereto and is incorporated herein by
     reference. See 'THE MERGER--Opinion of Morgan Stanley';
 
          8. the fact that the Merger offers the opportunity for substantial
     synergies and the transaction structure allows Revco stockholders who
     receive Rite Aid Common Stock to participate in those synergies through
     continued ownership of the combined company;
 
          9. the views expressed by management and Morgan Stanley that there did
     not appear to be any other party with which Revco would be as good a
     strategic fit as Rite Aid;
 
          10. the fact that the Stockholder agreed to tender all of its shares
     of Revco Common Stock in the Offer and to support the Merger Agreement;
 
          11. the fact that the Merger is not conditioned on the availability of
     financing;
 
          12. the fact that the Merger Agreement, which prohibits Revco, its
     subsidiaries or its affiliates from initiating, soliciting or encouraging
     any potential acquisition proposal, does permit Revco to furnish
     information to and participate in discussions or negotiations with any
     third party if certain conditions are satisfied;
 
          13. the fact that if the Revco Board decided to accept an acquisition
     proposal by a third party, the Revco Board may terminate the Merger
     Agreement and pay Rite Aid a termination fee of $45 million, or
     approximately $.68 per issued and outstanding share, which the Revco Board
     did not believe would be a significant deterrent to a higher offer by a
     third party interested in acquiring Revco; and
 
          14. the regulatory approvals required to consummate the Merger,
     including, among other things, antitrust approvals, and the prospects of
     receiving such approvals.

 
     The Revco Board did not assign relative weights to the above factors or
determine that any factor was of particular importance. Rather, the Revco Board
viewed its position and recommendations as being based on the totality of the
information presented to, and considered by, it.
 
     The Revco Board recognized that, while there can be no assurance as to the
level of growth or profits to be attained by Revco in the future and there can
be no assurance that the requisite FTC and other regulatory approvals for the
Merger will be obtained, the Merger and the transactions contemplated thereby
give Revco's stockholders the opportunity to receive Rite Aid Common Stock
pursuant to the Merger and thereby participate in the synergies expected to be
created by the combination of Revco with Rite Aid and the future growth and
profits of the combined company. See 'THE MERGER--Estimated Synergies.'
 
                                       40
<PAGE>
     It is presently expected that, if the Merger is not consummated, Revco's
management, under the general direction of the current Revco Board, will
continue to manage Revco as an ongoing business.
 
OPINION OF MORGAN STANLEY
 
     Revco retained Morgan Stanley to act as Revco's financial advisor in
connection with the Merger and related matters based upon Morgan Stanley's
qualifications, expertise and reputation, as well as Morgan Stanley's prior
investment banking relationship and familiarity with Revco. At the November 28,
1995 special meeting of the Revco Board, Morgan Stanley rendered an oral opinion
to the Revco Board that as of such date, the aggregate consideration to be
received by the holders of shares of Revco Common Stock pursuant to the Offer
(the 'Offer Consideration') and the aggregate consideration to be received by
the holders of shares of Revco Common Stock pursuant to the Merger (the 'Merger
Consideration' and, together with the Offer Consideration, the 'Consideration'),
taken together, were fair from a financial point of view to such holders. Morgan
Stanley subsequently confirmed its oral opinion by delivery of a written opinion
dated November 29, 1995.
 
     THE FULL TEXT OF MORGAN STANLEY'S WRITTEN OPINION DATED NOVEMBER 29, 1995,
WHICH SETS FORTH THE ASSUMPTIONS MADE, MATTERS CONSIDERED AND LIMITATIONS ON THE
REVIEW UNDERTAKEN, IS ATTACHED AS ANNEX C TO THIS PROXY STATEMENT AND IS
INCORPORATED HEREIN BY REFERENCE. MORGAN STANLEY'S OPINION IS DIRECTED ONLY TO
THE REVCO BOARD OF DIRECTORS AND THE FAIRNESS OF THE CONSIDERATION TO BE
RECEIVED BY THE HOLDERS OF SHARES OF REVCO COMMON STOCK PURSUANT TO THE OFFER
AND THE MERGER, TAKEN TOGETHER, FROM A FINANCIAL POINT OF VIEW TO THE HOLDERS OF
REVCO COMMON STOCK, AND IT DOES NOT ADDRESS ANY OTHER ASPECT OF THE MERGER NOR
DOES IT CONSTITUTE A RECOMMENDATION TO ANY HOLDER OF REVCO COMMON STOCK AS TO
HOW TO VOTE AT THE REVCO SPECIAL MEETING. THE SUMMARY OF THE OPINION OF MORGAN
STANLEY SET FORTH IN THIS PROXY STATEMENT IS QUALIFIED IN ITS ENTIRETY BY
REFERENCE TO THE FULL TEXT OF SUCH OPINION.
 
     In arriving at its opinion, Morgan Stanley: (i) analyzed certain publicly
available financial statements and other information of Revco and Rite Aid,
respectively; (ii) reviewed certain internal financial statements and other
financial and operating data concerning Revco and Rite Aid prepared by the

managements of Revco and Rite Aid, respectively; (iii) reviewed certain
financial projections for Revco and Rite Aid, including estimates of certain
potential benefits of the proposed business combination, prepared by the
managements of Revco and Rite Aid, respectively; (iv) discussed the past and
current operations and financial conditions and the prospects of Revco and Rite
Aid with senior executives of Revco and Rite Aid, respectively; (v) reviewed the
reported prices and trading activity for Revco Common Stock and Rite Aid Common
Stock; (vi) compared the financial performance of Revco and Rite Aid and the
prices and trading activity of Revco Common Stock and Rite Aid Common Stock with
that of certain other comparable publicly-traded companies and their securities;
(vii) reviewed the financial terms, to the extent publicly available, of certain
comparable acquisition transactions; (viii) participated in discussions among
representatives of Revco and Rite Aid and their legal advisors; (ix) reviewed
the Merger Agreement, Stock Option Agreement and the Stockholder Agreement; and
(x) performed such other analyses as it deemed appropriate.
 
     In rendering its opinion, Morgan Stanley assumed and relied without
independent verification upon the accuracy and completeness of the information
reviewed by Morgan Stanley for the purposes of this opinion. With respect to the
financial projections, including the estimates of Revco and Rite Aid of certain
potential benefits of the proposed business combination, Morgan Stanley assumed
that they were reasonably prepared on bases reflecting the best currently
available estimates and judgments of the future financial performance of Revco
and Rite Aid, respectively. Morgan Stanley did not make any independent
valuation or appraisal of the assets or liabilities of Revco and Rite Aid nor
was Morgan Stanley furnished with any such appraisals. Morgan Stanley's opinion
was necessarily based on economic, market, and other conditions as in effect on,
and the information made available to it as of November 29, 1995. In addition,
Morgan Stanley assumed that following completion of the Offer the Merger would
be consummated in accordance with the terms set forth in the Merger Agreement.
 
     Morgan Stanley was not authorized to solicit, and did not solicit, interest
from any party with respect to a merger with or other business combination
transaction involving Revco, or any of its assets, nor did Morgan Stanley have
any discussions with any parties, other than Rite Aid, in connection with the
Merger.

     The following is a brief summary of certain analyses performed by Morgan
Stanley and reviewed with the Revco Board on November 28, 1995 in connection
with Morgan Stanley's opinion to the Revco Board on such date:
 
          Revco Common Stock Performance.  Morgan Stanley's analysis of Revco's
     Common Stock performance consisted of a historical analysis of closing
     prices and trading volumes from November 17, 1992 to November 16, 1995;
     Revco's indexed price performance from November 17, 1994 to November 16,
     1995 relative to the S&P 500, Rite Aid and a Comparable Companies Index,
     which was comprised of Walgreen Co. and Eckerd Corporation; and the high
     and low prices in the twelve months ended November 16, 1995. The shares of
     Revco Common Stock have generally traded in line with both the Comparable
     Companies Index and the S&P 500 during the twelve months ending on November
     16, 1995. In the twelve months ended November 16, 1995, the shares of Revco
     Common Stock closed at a high of $25.375 per share and reached a low of

     $17.500 per share.
 
          Rite Aid Common Stock Performance.  Morgan Stanley's analysis of Rite
     Aid's Common Stock performance consisted of a historical analysis of
     closing prices and trading volumes from November 17, 1992 to November 16,
     1995; Rite Aid's indexed price performance from November 17, 1994 to
     November 16, 1995 relative to the S&P 500, Revco and a Comparable Companies
     Index, which was comprised of Walgreen Co. and Eckerd Corporation; and the
     high and low prices in the twelve months ended November 16, 1995. Rite Aid
     Common Stock has generally traded in line with both the Comparable
     Companies Index and the S&P 500 during the twelve months ending on November
     16, 1995. In the twelve months ended November 16, 1995, Rite Aid Common
     Stock closed at a high of $30.125 per share and reached a low of $21.625
     per share.
 
          Peer Group Comparison.  As part of its analysis, Morgan Stanley
     compared certain financial information of Rite Aid with that of a group of
     publicly traded drug store companies, including Eckerd Corporation, Longs
     Drug Stores Corporation, Revco, and Walgreen Co. (collectively, the 'Rite
     Aid Comparables'). Historical financial information used in connection with
     this analysis was as of the most recent financial statements publicly
     available for each company as of November 16, 1995. Such financial
     information included common stock market prices as a multiple of earnings
     per share ('EPS') for the latest twelve months ('LTM'), estimated EPS for
     calendar 1995, 1996, and 1997 based upon EPS estimates from the
     International Brokers Estimates System ('IBES'), and aggregate value
     (equity value plus debt minus cash) as a multiple of LTM revenues, earnings
     before interest and taxes ('EBIT'), earnings before interest, taxes,
     depreciation and amortization ('EBITDA'), and EBITDA less capital
     expenditures. In particular, such analyses indicated that as of November
     16, 1995, Rite Aid traded at 15.4x LTM earnings, 14.4x, 12.9x, and 11.6x
     IBES estimated earnings for the calendar years 1995, 1996, and 1997,
     respectively, and had aggregate value multiples of 0.65x LTM revenues,
     11.0x LTM EBIT, 8.1x LTM EBITDA, and 18.8x LTM EBITDA less capital
     expenditures. Morgan Stanley noted that the median multiples for the Rite
     Aid Comparables included equity multiples of 16.1x LTM earnings, 18.5x IBES
     estimated 1995 earnings, 16.3x IBES estimated 1996 earnings and 14.4x IBES
     estimated 1997 earnings, and aggregate value multiples of 0.50x LTM
     revenues, 12.4x LTM EBIT, 8.5x LTM EBITDA, and 14.0x LTM EBITDA less
     capital expenditures.
 
          No company utilized in the peer group analysis as a comparison is
     identical to Rite Aid. Accordingly, an analysis of the results of the
     foregoing necessarily involves complex considerations and judgements
     concerning financial and operating characteristics of Rite Aid and other
     factors that could affect the public trading value of one or more of the
     Rite Aid Comparables. Mathematical analysis (such as determining the
     average or the median) is not itself a meaningful method of using
     comparable company data.
 
          Historical Exchange Ratio Analysis.  Morgan Stanley also reviewed the
     ratio of the Revco Common Stock to Rite Aid Common Stock trading prices
     over varying intervals of time over the one year period ended November 16,
     1995. This ratio ranged from approximately 0.69 to 1.07 and, based on the

     closing price of Revco Common Stock and Rite Aid Common Stock on November
     16, 1995 of $23.875 and $27.50, respectively, the ratio was 0.87.
 
          Discounted Cash Flow Analysis.  Morgan Stanley performed a discounted
     cash flow analysis of Revco and Rite Aid for the fiscal years ended 1996
     through 2005 based on financial projections prepared by
 
                                       42
<PAGE>
     the respective managements of each company. Unlevered free cash flows of
     each company were calculated as net income available to common shareholders
     plus the aggregate of preferred stock dividends, depreciation and
     amortization, deferred taxes, and other non-cash expenses and after-tax net
     interest expense less the sum of capital expenditures and investment in
     non-cash working capital. Morgan Stanley calculated terminal values by
     applying a range of EBITDA multiples to the normalized unlevered free cash
     flows in fiscal 2005, representing estimated ranges of long-term EBITDA
     multiples for Revco and Rite Aid. The cash-flow streams and terminal values
     were then discounted to the present using a range of discount rates,
     representing an estimated range of the weighted average cost of capital for
     Revco and Rite Aid. Based on this analysis, Morgan Stanley calculated per
     share values for Revco ranging from $22.52 to $28.35 and for Rite Aid
     ranging from $22.58 to $29.25.
 
          Comparable Transaction Analysis.  Using publicly available
     information, Morgan Stanley performed an analysis of precedent transactions
     involving drugstore and other retail companies in order to calculate a
     valuation range for the Shares. Multiples to be received by the
     stockholders of Revco in the Offer and the Merger of aggregate value (fully
     diluted equity value of the Consideration plus any debt assumed less cash
     and option proceeds) to revenues, EBITDA, and EBIT and of fully diluted
     equity value to book value of equity and LTM earnings were compared with
     multiples paid in certain other merger and acquisition transactions
     involving drugstore and other retail companies from February 27, 1991 to
     June 28, 1995. The transactions included Rite Aid and Eckerd Corporation;
     Pathmark Stores Inc. and Rite Aid; Perry Drug Stores, Inc. and Rite Aid;
     Hook-SupeRX, Inc. and Revco, and Payless Drug Stores and TCH Corporation.
     Based on this analysis, aggregate value multiples with ranges of 0.35x to
     0.50x LTM revenues, 7.0x to 9.0x LTM EBITDA, and 13.0x to 15.0x LTM EBIT,
     and equity value multiples with ranges of 0.5x to 2.5x book value of equity
     and 18.0x to 22.0x LTM earnings were applied to Revco's corresponding
     financial statistics to suggest a median equity value range per share of
     Revco Common Stock of $17.42 to $26.74.
 
          No transaction utilized in the comparable transaction analysis is
     identical to the Offer and the Merger. Accordingly, an analysis of the
     results of the foregoing necessarily involves complex considerations and
     judgements concerning financial and operating characteristics of Revco and
     other factors that could affect the acquisition value of the companies to
     which it is being compared. Mathematical analysis (such as determining the
     average or median) is not itself a meaningful method of using comparable
     transaction data.
 
          Pro Forma Analysis of the Merger.  Morgan Stanley analyzed the pro

     forma impact of the Offer and the Merger on Revco earnings per share for
     the fiscal years ended 1997 through 2000. Such analysis was performed
     utilizing standalone earnings estimated for the fiscal years ended 1997
     through 2000 for Revco and Rite Aid based on IBES earnings estimates.
     Morgan Stanley analyzed the impact of the Offer and the Merger both with
     and without the cost savings expected to be derived from the Merger as
     estimated by the managements of Revco and Rite Aid.
 
     The preparation of a fairness opinion is a complex process and is not
necessarily susceptible to a partial analysis or summary description. Morgan
Stanley believes that its analyses must be considered as a whole and that
selecting portions of its analyses, without considering all analyses, would
create an incomplete view of the process underlying its opinion. In addition,
Morgan Stanley may have given various analyses more or less weight than other
analyses, and may have deemed various assumptions more or less probable than
other assumptions, so that the ranges of valuations resulting for any particular
analysis described above should not be taken to be Morgan Stanley's view of the
actual value of Revco and Rite Aid.
 
     In performing its analyses, Morgan Stanley made numerous assumptions with
respect to industry performance, general business and economic conditions and
other matters, many of which are beyond the control of Revco and Rite Aid. The
analyses performed by Morgan Stanley are not necessarily indicative of actual
value, which may be significantly more or less favorable than suggested by such
analyses. Such analyses were prepared solely as a part of Morgan Stanley's
analysis of whether the Consideration to be received by the holders of Revco
Common Stock pursuant to the Offer and the Merger, taken together, was fair from
a financial point of view to the holders of Revco Common Stock and were
conducted in connection with the delivery of Morgan Stanley's oral opinion of
November 28, 1995. The analyses do not purport to be appraisals or to reflect
the prices at which Revco and Rite Aid might actually be sold. Because such
estimates are inherently subject to uncertainty, none of Revco, Morgan Stanley,
or any other person assumes responsibility for their accuracy. In addition, as
described
 
                                       43
<PAGE>
above, Morgan Stanley's opinion and the information provided by it to the Revco
Board were two of many factors taken into consideration by the Revco Board in
making its determination to approve the Merger. Consequently, the Morgan Stanley
analyses described above should not be viewed as determinative of the opinion of
the Revco Board or the view of Revco management with respect to the value of
Revco or of whether the Revco Board or the management of Revco would have been
willing to agree to different consideration.
 
     The Revco Board retained Morgan Stanley based upon its experience and
expertise. Morgan Stanley is an internationally recognized investment banking
and advisory firm. As part of its investment banking business, Morgan Stanley is
regularly engaged in the valuation of businesses and securities in connection
with mergers and acquisitions, negotiated underwritings, competitive biddings,
secondary distributions of listed and unlisted securities, private placements
and valuation for estate, corporate and other purposes. In the ordinary course
of its business, Morgan Stanley and its affiliates may actively trade the debt
and equity securities of Revco and Rite Aid for their own account and for the

accounts of customers and, accordingly, may at any time hold a long or short
position in such securities. In the past, Morgan Stanley has provided financial
advisory and investment banking services to Revco and Rite Aid for which
services Morgan Stanley has received customary fees.
 
     The consideration to be received by the stockholders of Revco pursuant to
the Merger was determined through negotiations between Revco and Rite Aid and
was approved by the Revco Board. During the course of such negotiations, Morgan
Stanley did not make a recommendation with respect to the amount of the
Consideration.
 
     Pursuant to a letter agreement dated November 6, 1995 between Revco and
Morgan Stanley, Morgan Stanley is entitled to a fairness opinion fee of
$2,250,000. In addition, Revco has agreed to reimburse Morgan Stanley for its
expenses, including reasonable fees and expenses of its counsel, and to
indemnify Morgan Stanley and its affiliates against certain liabilities and
expenses, including liabilities under federal securities laws.
 
CERTAIN ADVANTAGES AND DISADVANTAGES OF THE MERGER
 
     In considering whether to approve the Share Issuance, stockholders of Rite
Aid should consider the following advantages and disadvantages.
 
     Advantages.  The Merger will provide significant benefits to Rite Aid and
its stockholders. The Merger will create substantial opportunities for synergies
and will allow the combined company to compete more effectively in a marketplace
that is becoming increasingly competitive.
 
     In addition, the Rite Aid Board has determined that the Merger is
advisable, fair to and in the best interests of the Rite Aid stockholders and
has approved the Merger Agreement.
 
     Morever, the Merger is expected to be accretive to Rite Aid's earnings per
share by the end of the first year of operations following the Merger.
Similarly, Rite Aid's management estimates, based on a preliminary review of
Revco's business and operations, that the Merger will result in approximately
$156 million of quantifiable annual cost savings, including improvement in gross
margins through enhanced purchasing power, closure of Revco's corporate
headquarters and overlapping distribution facilities, elimination of duplicative
overhead, elimination of redundant advertising expenditures, the consolidation
of data centers and improved communications systems and a working capital
benefit from the consolidation of warehouse inventories.
 
     Further, DLJ has delivered its opinion to the Rite Aid Board to the effect
that the consideration to be paid by Rite Aid pursuant to the Merger Agreement,
taken as a whole, is fair to the stockholders of Rite Aid from a financial point
of view. Similarly, Morgan Stanley has delivered its written opinion to the
Revco Board to the effect that the aggregate consideration to be received by the
holders of shares of Revco Common Stock pursuant to the Offer and the aggregate
consideration to be received by the holders of shares of Revco Common Stock
pursuant to the Merger, taken together, are fair from a financial point of view
to such holders.
 
     Disadvantages.  The Rite Aid Board considered the fact that Rite Aid would

be a more leveraged company in the event that the Share Issuance was not
approved by Rite Aid's stockholders and the Merger was consummated using the
Alternative Consideration.
 
     In determining that the Merger is advisable and in the best interests of
its stockholders, the Rite Aid Board considered the cost savings, operating
efficiencies and other synergies expected to result from the consummation
 
                                       44
<PAGE>
thereof. The consolidation of functions, the integration of departments, systems
and procedures and the relocation of staff present significant management
challenges. There can be no assurance that such actions will be successfully
accomplished as rapidly as currently expected. Moreover, although the primary
purpose of such actions will be to realize direct cost savings and other
operating efficiencies, there can be no assurance of the extent to which such
cost savings and efficiencies will be achieved.
 
   
     If the stockholders of Rite Aid approve the Share Issuance and assuming a
one-for-one Exchange Ratio, the current stockholders of Rite Aid would own
approximately 72.7% of the then outstanding shares of Rite Aid Common Stock
after the Merger.
    
 
   
     Rite Aid also expects to take a pre-tax charge to earnings estimated to be
in the range of $150 million to $175 million to cover the cost of integrating
the two companies. See Note (n) of Notes to Unaudited Pro Forma Condensed
Consolidated Financial Data for a discussion of such merger and integration
charges. There can be no assurance, however, that the amount of such charge will
not increase as Rite Aid's integration plan is further developed and more
accurate estimates become possible or as to the amount of the after-tax cost of
such charge.
    
 
PLANS FOR REVCO
 
   
     It is expected that, initially following the Merger, the business and
operations of Revco will be integrated into the operations of Rite Aid as
rapidly as practicable following the Merger. Rite Aid intends to close Revco's
corporate headquarters at 1925 Enterprise Parkway, Twinsburg, Ohio (the
'Headquarters') within twelve months following consummation of the Merger and to
integrate Revco's corporate headquarters operations into Rite Aid's operations.
Rite Aid also expects to take a pre-tax charge to earnings estimated to be in
the range of $150 million to $175 million to cover the cost of integrating the
two companies. Rite Aid anticipates that only a small percentage of the combined
stores of Rite Aid and Revco will be closed. A decision on which stores will be
closed is not expected to be made until after the consummation of the Merger. In
addition, Rite Aid will continue to evaluate the business and operations of
Revco after the consummation of the Merger, and will take such further actions
as it deems appropriate under the circumstances then existing.
    

 
INTERESTS OF CERTAIN PERSONS
 
     Certain members of Revco's management and Revco's Board may be deemed to
have certain interests in the Merger that are in addition to their interests as
stockholders of Revco generally. The Revco Board was aware of these interests
and considered them, among other matters, in approving the Merger Agreement and
the transactions contemplated thereby.
 
     Described below under 'Existing Arrangements' are material employment and
employee benefit agreements and arrangements as they currently exist. Pursuant
to the terms of the Merger Agreement, certain terms and conditions of such
agreements and arrangements will be amended. A description of such amendments
follows under the heading 'The Merger Agreement.'
 
  EXISTING ARRANGEMENTS
 
     Existing Employment Agreements.  Revco maintains employment agreements
with, among others, its eight executive officers and fifteen other officers
(collectively, the 'Covered Executives' or, individually, a 'Covered
Executive'), with one form of agreement for executive officers and one form of
agreement for non-executive officers. Except for the severance period (described
below), the forms of these agreements are substantially similar. The significant
provisions of the agreements are as follows:
 
          1. Term of the Agreement.  The agreements continue until terminated by
     reason of (a) the employee's death, (b) the employee's disability, (c)
     thirty days' written notice of termination by either Revco or the employee,
     (d) notice by the employee of his resignation for 'good reason' (as defined
     below), or (e) notice by Revco of the employee's 'gross misconduct' (as
     defined below). For purposes of the employment agreements, 'good reason'
     means (i) the occurrence of a material reduction in the aggregate direct
     remuneration of the employee or any reduction in the position of the
     employee, (ii) any material reduction in responsibilities or duties
     provided for in accordance with employee's arrangement with Revco, (iii)
     any material adverse change or reduction in the aggregate employee
     benefits, perquisites or fringe benefits contemplated under such
     arrangement, (iv) a change in the employee's reporting relationship, or (v)
     any
 
                                       45
<PAGE>
     relocation of the employee's principal place of work. For purposes of the
     employment agreements, 'gross misconduct' includes, but is not limited to,
     (i) commission of an act of fraud, embezzlement, theft, or other criminal
     act constituting a felony, or (ii) breach or default by the employee of any
     of his agreements or obligations under the agreement which is not cured in
     all substantial respects within ten days after Revco gives notice to the
     employee of such breach or default.
 
          2. Salary and Bonus.  The agreements provide for the payment of base
     salary and participation in Revco's bonus plan, described more fully below.
     The following table summarizes Revco's executive officers (hereinafter
     referred to as 'Group A Executives'), their positions and their base

     salaries:

Clarence D. Nichols.......  Senior VP, Store Operations                             $ 226,740
Jack A. Staph.............  Senior VP, Secretary and General Counsel                $ 247,323
</TABLE>
 
          3. Other Benefits.  The agreements provide that the employee will be
     eligible to participate in Revco's other employee benefit programs for the
     provision of welfare and other benefits.
 
          4. Severance.  The agreements provide for the payment of an employee's
     base salary and the continuation of other benefits for a specified period
     upon termination of employment by Revco other than for gross misconduct or
     by the employee for good reason. The severance period for Group A
     Executives is two years and, for the other fifteen officers ('Group B
     Executives'), is one year.
 
     Economic Value Added (EVA) Incentive Plan (the 'Bonus Plan').  Each of the
Covered Executives is eligible to participate in the Bonus Plan. Awards pursuant
to the Bonus Plan are based upon the achievement of a combination of performance
objectives by Revco and the individual participant. Each participant in the
Bonus Plan is credited with bonus units equal to his base salary multiplied by a
target bonus percentage. If the target bonus is exceeded by a specified amount,
the excess is deposited into a bonus bank on behalf of the individual
participant for the following year.
 
     Defined Benefit Plan.  The Revco Retirement Income Plan and Trust, as
amended ('Pension Plan'), is a defined benefit pension plan generally covering
employees of Revco, other than those covered by collective bargaining agreements
that provide for pension benefits.
 
     On reaching normal retirement at or after age 65, a participant is
generally entitled to receive a monthly retirement benefit for life. Alternative
actuarially equivalent forms of benefit payments are provided for in the Pension
Plan. Vesting under the Pension Plan occurs after five years of service (with no
vesting where less than five years of service has been completed).
 
     The annual retirement benefit at the normal retirement age of at least 65
is equal to an amount which, when added to the participant's social security
benefit, is the product of the employee's average earnings for the last five
years of his service and the applicable percentage set forth in the table below.
If the employee has fewer than 30 years of credited service with Revco, the
benefit determined by this formula is reduced by a percentage determined

substantially by the ratio of the number of years of credited service to 30. A
participant who has attained age 55 and has completed five years of service may
elect early retirement with reduced monthly benefit payments.
 
                                       46
<PAGE>
     The amounts shown in the following table are based on the pension being
paid during the lifetime of the retired employee only, including social security
benefits, and would be reduced for service of less than 30 years and on an
actuarially equivalent basis in the event of a survivor benefit or other
optional form of payment.

- ------------------
(1) For plan years beginning on or after January 1, 1989, the Internal Revenue
    Code of 1986, as amended (the 'Code'), limits the amount of compensation
    that can be used for plan calculation purposes to $200,000 (indexed). For
    plan years beginning on or after January 1, 1994, this limit is reduced to
    $150,000 (indexed).
 
* As required by the Code, plan payments may not provide annual benefits
  exceeding a maximum amount, currently $120,000.
 
     Supplemental Retirement and Survivor Benefit Plan (the 'SERP').  Each of
the Covered Executives participates in the SERP, which provides supplemental
retirement benefits generally commencing upon either (i) retirement or
disability at age sixty, or (ii) upon termination of employment at age
sixty-five. The basic supplemental benefit is an amount that, when added to
other benefits (pension plan benefits, social security benefits and other
monthly retirement income as provided), equals 70% of a participant's final
salary. The SERP benefit is reduced for early retirement. Upon execution of an
individual agreement under the SERP, a participant is 50% vested. Thereafter, a
participant vests in his SERP benefits at a rate of 10% each year. Mr. Hoven and
Mr. Staph are eligible for a reduced early retirement benefit, which is provided
for a participant who is at least fifty-five years of age and has at least ten
years of service. Such benefits, reduced by estimated social security and
pension plan benefits, are also subject to a reduction based upon age on a scale
from 40% at age fifty-five to a maximum of 70% at age sixty-five.
 
     Split Dollar Plan.  Each of the Covered Executives participates in the
Split Dollar Plan which provides that beneficiaries designated by participants
will receive insurance proceeds equal to a multiple of base salary measured in
the year preceding death. Revco is the direct beneficiary of the proceeds, if
any, in excess of the
 
                                       47
<PAGE>
proceeds as calculated in the preceding sentence. At the end of each calendar
year a participant's pay is 'grossed up' to pay any tax liability for imputed
income resulting from Revco's payment of premiums. Participation in the Split
Dollar Plan ceases upon a participant's termination of employment for any reason
other than death or permanent disability.
 
     1992 Long-Term Incentive Plan (the 'LTIP').  Each of the Covered Executives
participates in the LTIP, which provides for the grant of incentive and
non-qualified stock options, reload options, stock appreciation rights,
restricted stock awards, stock bonus awards and performance plan awards. To
date, long-term incentive awards granted under the LTIP have consisted solely of
non-qualified stock options. Pursuant to the LTIP, generally 20% of the options
are immediately exercisable upon the date of grant. Thereafter, an additional
20% of the options become exercisable each year until 100% of the options become
exercisable five years from the date of grant. The exercise price of the options
granted increases annually by 5% until the shares subject to the option vest. In
the event of a 'change in control,' as defined in the LTIP, the options granted
to Revco's officers become fully exercisable. The consummation of the Offer

constitutes a 'change in control' for purposes of the LTIP. Option awards to
Group A Executives contain a gross-up provision for excise taxes resulting from
application of Sections 280G and 4999 of the Code.
 
     The estimated amount of gain associated with the options of Group A
Executives that vest upon a 'change in control' is:
 
<TABLE>

Mr. Staph...................................................  $    942,912
</TABLE>
 
     The estimated aggregate amount of gain associated with the options of Group
B Executives that vest upon a 'change in control' is approximately $3,200,000.
 
     1992 Non-Employee Directors' Stock Option Plan (the 'Non-Employee
Directors' Plan').  All of the directors who are not officers or key employees
of Revco are eligible to participate in the Non-Employee Directors' Plan, which
provides for the grant of options to purchase shares of Revco's common stock.
The options vest at a rate of 20% each year until they are 100% exercisable
after five years from the date of grant. The exercise price of the options
granted increases annually by 5% until the shares subject to the options vest.
In the event of a 'change in control,' as defined in the Non-Employee Directors'
Plan, the options granted to the participants become fully exercisable. The
consummation of the Offer constitutes a 'change in control' for purposes of the
Non-Employee Directors' Plan. The estimated aggregate amount of gain associated
with the options of non-employee Directors that vest upon a 'change in control'
is approximately $577,000.
 
     Employee Stock Purchase Plan (the 'ESPP').  Each of the Covered Executives
is eligible to participate in the ESPP, which permits participants to purchase
Revco's common stock at the lesser of (a) 85% of the fair market value of the
stock on the first day of the offering period, or (b) 85% of the fair market
value of the stock on the last day of the offering period.
 
  THE MERGER AGREEMENT
 
     The Merger Agreement provides that, effective as of the Effective Time,
Rite Aid will cause the Surviving Corporation to provide to employees of Revco
certain payments and benefits, as described below.
 
     Treatment of Stock Options.  The Merger Agreement provides that, effective
as of the Effective Time, each option granted by Revco to purchase shares of
Revco Common Stock that is outstanding and unexercised immediately prior thereto
(the 'Revco Stock Options'), will cease to represent a right to acquire shares
of Revco Common Stock and will be converted automatically into an option to
purchase shares of Rite Aid Common Stock in an amount and at an exercise price

determined as provided below (and otherwise subject to the terms of the LTIP and
the Non-Employee Directors' Plan (together the 'Option Plans'), and the
agreements evidencing grants thereunder). The number of shares of Rite Aid
Common Stock subject to, and the option price and terms
 
                                       48
<PAGE>
and conditions of, the new option shall be determined in a manner that preserves
both (i) the aggregate gain (or loss) on Revco Stock Options immediately prior
to the Effective Time and (ii) the ratio of the exercise price per share subject
to Revco Stock Options to the fair market value (determined immediately prior to
the Effective Time) per share subject to such option, provided that any
fractional shares of Rite Aid Common Stock resulting from such determination
will be rounded down to the nearest share. The Merger Agreement also provides
that, effective as of the Effective Time, the Surviving Corporation will assume
each Revco Stock Options agreement, each as amended, as provided therein. The
duration, vesting and other terms of the new options will be the same as Revco
Stock Options that they replace, except that all references to Revco shall be
deemed to be references to Rite Aid. In the event that a holder of a Revco Stock
Option is terminated without Cause (as defined in the Merger Agreement) within
12 months of the Effective Time, then such holder's new option will become 100%
exercisable as of such date of termination.
 
     The Merger Agreement further provides that, notwithstanding the immediately
preceding paragraph, outstanding vested options under the LTIP held by Covered
Executives, including options that become vested in connection with a 'change in
control' under the terms of existing award agreements under the LTIP, will,
effective as of the Effective Time, become exercisable under a cashless exercise
procedure made available by Revco (subject to applicable law and any
administrative procedures and policies deemed appropriate by Revco). Individuals
subject to Section 16 of the Exchange Act ('Section 16') will be provided with a
cash payment approximating the benefits that would be deprived by reason of
Section 16.
 
     The Merger Agreement provides that, effective as of the Effective Time, the
Option Plans will terminate and the provisions in any other plan, program,
agreement or arrangement providing for the issuance or grant of any other
interest in respect of the capital stock of Revco or any of its Subsidiaries,
will be deleted. Furthermore, Revco will take all actions necessary to ensure
that following the Effective Time, no holder of Revco Stock Options or any
participant in the Option Plans or any other plans, programs, agreements or
arrangements will have any right thereunder to acquire any equity securities of
Revco, the Surviving Corporation or any subsidiary of either of the foregoing.
 
     Bonus; Severance Benefits.  As soon as practicable following the earlier of
(i) the Effective Time and (ii) the end of Revco's 1996 fiscal year, Revco will
pay, pursuant to the terms of the Bonus Plan as modified by the terms of the
Merger Agreement, bonuses for fiscal year 1996, calculated based on Revco's
financial results as of February 10, 1996, and annualized to equal a bonus for a
twelve month period.
 
     With respect to the Covered Executives, effective as soon as practicable
following the Effective Time (or if later, the date of termination of employment
of the Covered Executive), Revco will pay to each Covered Executive severance

payments (the 'Severance Payments'), on a basis consistent with Rite Aid's
executive payroll practices, based on one of the two formulae set forth below,
pursuant to elections made by each Covered Executive prior to the Effective
Time:
 
          (i) Severance Payments equal to, on an annualized basis, 'Base Pay'
     (as defined below), continuing for a period of three years with respect to
     Group A Executives, and for a period of 18 months with respect to Group B
     Executives. For purposes of this provision, 'Base Pay' means the highest
     base pay paid to the Covered Executive during any one of the 1994, 1995 or
     1996 fiscal years, provided that Base Pay for fiscal year 1996 will be
     calculated on an annualized basis; or
 
          (ii) Severance Payments equal to, on an annualized basis, 'Base Plus
     Bonus Pay' (as defined below), continuing for a period of two years with
     respect to Group A Executives, and for a period of one (1) year with
     respect to Group B Executives. For purposes of this provision 'Base Plus
     Bonus Pay' means Base Pay plus the amount that would have been paid to the
     executive under the Bonus Plan for fiscal year 1995 as the targeted bonus
     (the '1995 Target Bonus').
 
     In lieu of the Severance Payments described in clauses (i) and (ii) above,
Mr. Hoven and Mr. Mastrian will receive Severance Payments, continuing for three
years, equal to, on an annualized basis, Base Plus Bonus Pay.
 
     The period during which a Covered Executive continues to receive Severance
Payments is hereinafter referred to as the 'Severance Period' for such Covered
Executive.
 
                                       49
<PAGE>
     The estimated cost of providing the additional severance payments to Group
A Executives upon termination of employment is:
 
<TABLE>
<S>                                                           <C>
Mr. Hoven...................................................  $1,726,943
Mr. Bellini.................................................  $  420,000
Mr. Hagan...................................................  $  270,000
Mr. Mastrian................................................  $  701,496
Mr. Coffey..................................................  $  245,700
Mr. Gropp...................................................  $  203,963
Mr. Nichols.................................................  $  226,740
Mr. Staph...................................................  $  247,323
</TABLE>
 
     The aggregate estimated cost of providing the additional severance payments
to Group B Executives is $1,190,738.
 
     During the Severance Period, each Covered Executive will continue to
receive, at Revco's expense, continuation of benefits described in such Covered
Executive's employment agreement with Revco on terms at least as favorable to
the Covered Executive as is currently in effect, which benefits may be provided
under benefit plans and programs maintained by Rite Aid; provided, however, that

to the extent any such Covered Executive receives comparable benefits from, and
at the expense of, a subsequent employer, such benefits from the Surviving
Corporation will cease.
 
     Notwithstanding anything to the contrary in the Merger Agreement, the
Severance Payments described in clauses (i) and (ii) above will be paid to a
Covered Executive only if such Covered Executive is actively employed by Revco
immediately prior to the Effective Time. In the event that a Covered Executive
who continues employment with Revco following the Effective Time is terminated
prior to the expiration of the Severance Period that would have applied had such
Covered Executive been terminated effective as of the Effective Time, then such
Covered Executive will be entitled to receive the Severance Payments described
above.
 
   
     Each employee, other than any Covered Executive, of Revco who is covered by
Revco's severance pay plan as in effect on November 1, 1995 (each, a
'Severance-Eligible Employee') and who is employed by Revco immediately prior to
the Effective Time and terminated for other than Cause (as defined below) within
twelve months following the Effective Time, will be entitled to receive
bi-weekly severance payments, made on a basis consistent with Rite Aid's payroll
practices, for a six month period commencing on such Severance-Eligible
Employee's date of termination of employment, equal to, on an annualized basis,
such Severance-Eligible Employee's Base Pay; provided, however, that except for
employees located at Revco's headquarters such payments will be reduced (but not
below zero) by the amount of compensation such Severance-Eligible Employee
receives from a subsequent employer to the extent that such Severance-Eligible
Employee is employed during such six month period.
    
 
     For purposes of the Merger Agreement, 'Cause' will mean the conviction of
an employee or executive (as the case may be) for the commission of a felony,
including the entry of a guilty or nolo contendere plea, any willful, grossly
negligent or fraudulent action or inaction by an employee or executive, as the
case may be, or the employee's or executive's willful and continued failure to
substantially perform an employee's or executive's assigned duties.
 
     SERP.  Each Revco employee who is (i) covered by the SERP and (ii) actively
employed by Revco, in either case, immediately prior to the Effective Time
(each, a 'SERP Executive') will be eligible to receive benefits under the SERP
based on the terms of the SERP as modified by the terms of the Merger Agreement.
For each SERP Executive (i) the amount of service taken into account for
purposes of calculating benefits and vesting under the SERP will be equal to the
SERP Executive's service with Revco prior to the Effective Time plus the Covered
Executive's Severance Period, if any, and (ii) compensation for each SERP
Executive for purposes of the SERP will include one-half of the 1995 Target
Bonus for such SERP Executive.

     The estimated present value (using a 7.5% discount factor) of the
additional SERP and Split Dollar Plan benefits for the Group A Executives is:
 
<TABLE>

<S>                                                           <C>
Mr. Hoven...................................................  $1,503,112
Mr. Bellini.................................................  $1,877,388

Mr. Nichols.................................................  $  161,405
Mr. Staph...................................................  $  191,735
</TABLE>
 
     The aggregate estimated present value (using a 7.5% discount factor) of the
additional SERP and Split Dollar Plan benefits for Group B Executives is
$762,150.
 
     Gross-Up Payments.  Revco will provide each Group A Executive with a cash
gross-up payment to make such executive whole for the excise taxes imposed on
all benefits and other amounts paid or payable to such executive on account of
the transactions contemplated by the Merger Agreement as a result of the
application of Sections 280G and 4999 of the Code. With respect to all other
employees of Revco who are entitled to benefits and other amounts paid or
payable to such employee on account of the transactions contemplated by the
Merger Agreement as a result of the application of Sections 280G and 4999 of the
Code, Revco shall not be obligated to pay or provide to any such employee any
payments or benefits to the extent that such payments or benefits would
constitute a 'parachute payment' within the meaning of Section 280G(b)(2)(A) of
the Code.
 
     Based upon preliminary estimates, the aggregate cost of the gross-up
payments is expected to be between $6,000,000 and $9,000,000.
 
     ESPP.  Each Covered Executive who is subject to Section 16 will be provided
with a cash payment approximating the benefits that would be deprived by reason
of Section 16. Revco will amend the ESPP to provide that the option period that
was in effect as of November 29, 1995 will cease as soon as practicable
thereafter.
 
     Other Benefits.  Revco will provide outplacement services from a recognized
outplacement provider selected by Rite Aid to all employees of Revco as of the
Effective Time who were based in Twinsburg, Ohio as of the Effective Time, and
are terminated without Cause within one (1) year of the Effective Time.
 
     In addition, pursuant to the Merger Agreement, employees of Revco who
continue to be employed by Revco as of the Effective Time will receive employee
benefits comparable to those benefits provided to similarly situated employees
of Rite Aid. In addition, with respect to medical benefits provided to
continuing employees as of the Effective Time, waiting periods and pre-existing
condition requirements under the plans covering the continuing employees will be
waived, and these employees will be given credit for any co-payments and
deductibles actually paid by such employees under Revco's medical plans during
the calendar year in which the closing of the Merger occurs. Finally, service
with Revco will be recognized for purposes of eligibility under Rite Aid's
welfare plans as well as for purposes of Rite Aid's programs or policies for
vacation pay and sick pay.

 
     Certain additional information with respect to executive compensation and
related employee benefits and other information concerning Revco's executive
officers and directors, as modified by the foregoing discussion set forth in
this Proxy Statement, is set forth in the 1995 Revco Proxy Statement under the
sections titled 'The Board of Directors--Compensation of the Board,' 'Security
Ownership of Certain Persons,' 'Executive Compensation' and 'Report of the Human
Resources Committee' and is incorporated herein by reference.
 
INDEMNIFICATION
 
     Pursuant to the terms of the Merger Agreement, Rite Aid has agreed that at
all times after the Effective Time, it will indemnify, or will cause Revco, as
the surviving corporation, and its subsidiaries to indemnify each director,
officer, employee or agent of Revco or any of Revco's subsidiaries, successors
and assigns (an 'Indemnified Party'), to the fullest extent permitted by law,
with respect to any claim, liability, loss, damage, judgment, fine, penalty,
amount paid in settlement or compromise, cost or expense, including reasonable
fees and expenses of legal counsel (whenever asserted or claimed) ('Indemnified
Liability') based in whole or in part on, or arising in whole or in part out of,
any matter existing or occurring at or prior to the Effective Time. Rite Aid
 
                                       51
<PAGE>
has also agreed to maintain certain directors and officers liability insurance
for four years following the Merger as set forth in the Merger Agreement. See
'MERGER AGREEMENT--Directors' and Officers' Insurance and Indemnification.'
 
CERTAIN PROJECTED FINANCIAL INFORMATION
 
     In the course of its discussions with DLJ in November 1995, Revco provided
DLJ with certain business and financial information which DLJ and Revco believe
was not publicly available. Such information included, among other things,
certain financial projections for fiscal 1996 through fiscal 1998 prepared by
management of Revco as a long-range plan (the 'Projections'). The Projections do
not take into account any of the potential effects of the transactions
contemplated by the Merger.
 
     Set forth below is a selected summary of the Projections.

     THE PROJECTIONS WERE NOT PREPARED WITH A VIEW TO PUBLIC DISCLOSURE OR
COMPLIANCE WITH PUBLISHED GUIDELINES OF THE COMMISSION OR THE GUIDELINES
ESTABLISHED BY THE AMERICAN INSTITUTE OF CERTIFIED PUBLIC ACCOUNTANTS. THE
PROJECTIONS ARE INCLUDED IN THIS PROXY STATEMENT ONLY BECAUSE SUCH INFORMATION
WAS PROVIDED TO DLJ. NONE OF RITE AID, SUB, DLJ OR ANY PARTY TO WHOM THE
PROJECTIONS WERE PROVIDED ASSUMES ANY RESPONSIBILITY FOR THE ACCURACY OF SUCH
INFORMATION. WHILE PRESENTED WITH NUMERICAL SPECIFICITY, THESE PROJECTIONS ARE
BASED UPON A VARIETY OF ASSUMPTIONS RELATING TO THE BUSINESS OF REVCO WHICH,
THOUGH DLJ HAS BEEN ADVISED WERE CONSIDERED REASONABLE BY REVCO AT THE TIME THEY
WERE FURNISHED TO DLJ, MAY NOT BE REALIZED AND ARE SUBJECT TO SIGNIFICANT
UNCERTAINTIES AND CONTINGENCIES, MANY OF WHICH ARE BEYOND THE CONTROL OF REVCO.
THERE CAN BE NO ASSURANCE THAT THE PROJECTIONS WILL BE REALIZED, AND ACTUAL

RESULTS MAY VARY MATERIALLY FROM THOSE SHOWN. FOR THESE REASONS, AS WELL AS THE
BASES ON WHICH SUCH PROJECTIONS WERE COMPILED, THERE CAN BE NO ASSURANCE THAT
SUCH PROJECTIONS WILL BE REALIZED, OR THAT ACTUAL RESULTS WILL NOT BE HIGHER OR
LOWER THAN THOSE ESTIMATED. THE INCLUSION OF SUCH PROJECTIONS HEREIN SHOULD NOT
BE REGARDED AS AN INDICATION THAT RITE AID, SUB, DLJ OR ANY OTHER PARTY WHO
RECEIVED SUCH INFORMATION CONSIDERS IT AN ACCURATE PREDICTION OF FUTURE EVENTS.
 
     THE INDEPENDENT ACCOUNTANTS FOR RITE AID AND REVCO HAVE NOT EXAMINED OR
COMPILED THESE PROJECTIONS AND ACCORDINGLY DO NOT EXPRESS AN OPINION OR ANY
OTHER FORM OF ASSURANCE ON THEM.
 
ESTIMATED SYNERGIES
 
     Upon consummation of the Merger, Rite Aid intends to continue to review
Revco and its assets, businesses, operations, properties, policies, corporate
structure, capitalization and management and consider if any changes would be
desirable in light of the circumstances then existing. Upon consummation of the
Merger, Rite Aid intends to review the business of Revco and identify synergies
and cost savings.
 
     Rite Aid regards the resulting consolidation of Revco and Sub as an
opportunity to achieve certain cost savings and synergies. Based on a
preliminary review of Revco's business and operations, Rite Aid currently
estimates that the Merger will result in approximately $156 million of
quantifiable annual cost savings, including the improvement in gross margins
through enhanced purchasing power, closure of Revco's corporate headquarters and
overlapping distribution facilities, elimination of duplicative overhead,
elimination of redundant advertising expenditures, the consolidation of data
centers and improved communications systems and a working capital benefit from
the consolidation of warehouse inventories. THE FOREGOING ESTIMATES OF COST
SAVINGS AND SYNERGIES ARE INHERENTLY SUBJECT TO SIGNIFICANT UNCERTAINTIES AND
CONTINGENCIES, MANY OF WHICH ARE BEYOND THE CONTROL OF RITE AID. THERE CAN BE NO
ASSURANCE THAT THEY WILL BE ACHIEVED AND ACTUAL SAVINGS AND SYNERGIES MAY VARY
MATERIALLY FROM THOSE ESTIMATED. THE INCLUSION OF SUCH ESTIMATES HEREIN SHOULD
NOT BE REGARDED AS AN INDICATION THAT RITE AID, SUB OR ANY OTHER PARTY CONSIDERS
SUCH ESTIMATES AN ACCURATE PREDICTION OF FUTURE EVENTS.
 
FINANCING THE TRANSACTION
 
   
     Rite Aid estimates that the total amount of funds required for the Offer
and the Merger, to refinance Revco's indebtedness and to pay related fees and
expenses will be approximately $2.5 billion.
    
 
     Rite Aid intends to obtain a portion of the funds for the purchase of
shares of Revco Common Stock in the Offer pursuant to a Credit Agreement, (the
'Credit Agreement'), to be entered into among Rite Aid, Morgan Guaranty Trust
Company of New York, as Agent ('Morgan Guaranty') and the other banks (the
'Banks') named therein, which provides Rite Aid with a revolving credit facility
in the amount of $2.5 billion (the 'Credit
 
                                       53
<PAGE>

Facility') which will terminate, and all outstanding loans shall be due and
payable, on February 15, 2001. The Credit Agreement requires that (x) the
commitments thereunder be reduced to $1.5 billion no later than the second
anniversary of the closing date of the Offer and (y) that the net cash proceeds
from the issuance by Rite Aid of any equity or long term debt securities be
applied to the reduction of the commitments until they have been so reduced to
$1.5 billion.
 
     The Credit Agreement provides that the interest rate on base rate loans
from the Banks under the Credit Facility is to be at a rate per annum equal to
the higher of (i) the prime rate and (ii) the sum of 1/2 of 1% plus the rate per
annum equal to the weighted average of the rates on overnight Federal funds
transactions with members of the Federal Reserve System arranged by Federal
funds brokers. The Credit Facility provides for other interest rates with
respect to CD loans, Euro-Dollar loans, and money-market London Interbank
Offered Rate loans. The effective interest rates will vary depending on the
ratings of Rite Aid's long term senior debt.
 
     The Credit Agreement contains certain covenants including, among others,
(i) restrictions that the aggregate amount of indebtedness of Rite Aid and its
subsidiaries will not exceed $3 billion at any time prior to February 15, 1997,
(ii) restrictions on sales with leases back, (iii) maintenance of a maximum
leverage ratio (debt to equity) with required reductions over time, (iv)
maintenance of a minimum fixed charge coverage ratio that increases over time,
(v) restrictions on subsidiary indebtedness and (vi) restrictions on
consolidations, mergers, sales of assets, minority investments and the creation
of liens.
 
   
     In order to consummate the Offer, Rite Aid expects to obtain approximately
$966.5 million pursuant to the Credit Agreement. In the event that the average
per share value of Rite Aid Common Stock determined during the Pricing Period is
less than $27.50, Rite Aid will obtain additional funds pursuant to the Credit
Agreement and/or Rite Aid's working capital in order to deliver any Cash
Adjustment Amount to Revco stockholders (but only in the event such an election
to pay the Cash Adjustment Amount is made by Rite Aid).
    
 
     In the event that stockholders of Rite Aid do not approve the Share
Issuance at the Rite Aid Special Meeting, Rite Aid estimates that up to $3
billion (or an additional $500 million in excess of the amount necessary if such
stockholder approval is obtained in the Merger) will be required to consummate
such refinancing and to pay for the remaining shares of Revco Common Stock. In
this connection Rite Aid has received a letter, dated November 16, 1995, from
J.P. Morgan (the 'J.P. Morgan Letter') which states that, subject to the
conditions described therein, J.P. Morgan is 'highly confident' that in the
event that the stockholders of Rite Aid do not approve the proposed issuance of
Rite Aid Common Stock, an aggregate amount of up to $3 billion can be raised by
Rite Aid in the syndicated bank market.
 
     In the event Rite Aid becomes obligated to deliver the Additional
Consideration pursuant to the Merger Agreement, Rite Aid will obtain the
additional funds needed pursuant to the Credit Agreement and/or Rite Aid's
working capital.

 
     Any remaining costs of the Offer and the Merger will be obtained from funds
pursuant to the Credit Agreement and/or Rite Aid's working capital.
 
     No final decisions have been made concerning the method Rite Aid will
employ to repay such indebtedness. Such decisions when made will be based on
Rite Aid's review from time to time of the advisability of particular actions,
as well as on prevailing interest rates and financial and other economic
conditions.
 
ACCOUNTING TREATMENT
 
     The Merger will be accounted for under the 'purchase' method of accounting
in accordance with generally accepted accounting principles ('GAAP').
 
OTHER LEGAL MATTERS; REGULATORY APPROVALS
 
     General.  Except as otherwise disclosed herein, based upon its review of
publicly available information with respect to Revco and the review of certain
information furnished by Revco to Rite Aid, neither Sub nor Rite Aid is aware of
(i) any license or regulatory permit that appears to be material to the business
of Revco and its subsidiaries, taken as a whole, that might be adversely
affected pursuant to the Merger or (ii) any approval or other action by any
governmental, administrative or regulatory agency or authority, domestic or
foreign, that
 
                                       54
<PAGE>
would be required for the consummation of the Merger. Should any such approval
or other action be required, Rite Aid and Sub currently contemplate that such
approval or action would be sought. Revco's pharmacists and pharmacy technicians
are required to be licensed by the appropriate state board of pharmacy. Revco's
stores and certain of Revco's distribution centers are also registered with the
Federal Drug Enforcement Administration. Many of Revco's stores sell alcoholic
beverages and are subject to various state and local licensing requirements as a
result. By virtue of these license and registration requirements, Revco may be
obligated to obtain certain governmental consents and approvals in order to
consummate the Merger. While Rite Aid does not currently intend to delay the
Merger pending the outcome of any such matter, there can be no assurance that
any such approval or action, if needed, would be obtained or would be obtained
without substantial conditions or that adverse consequences might not result to
the business of Revco, Sub or Rite Aid or that certain parts of the businesses
of Revco, Sub or Rite Aid, might not have to be disposed of in the event that
such approvals were not obtained or any other actions were not taken.
 
   
     Antitrust.  Under the HSR Act and the regulations promulgated thereunder by
the FTC, the Offer may not be consummated until notifications have been given
and certain information has been furnished to the FTC and the Antitrust Division
and the applicable waiting period has expired or been terminated. The
consummation of the Offer is conditioned upon the expiration or termination of
the applicable waiting period under the HSR Act. On December 11, 1995, Rite Aid
and Revco filed notifications and report forms under the HSR Act with the FTC
and the Antitrust Division. On December 27, 1995, Rite Aid and Revco received

the Second Request from the FTC. Under the applicable HSR Act regulations, the
Offer may not be consummated until 10 days after Rite Aid has substantially
complied with the Second Request or the Second Request has been withdrawn by the
FTC and termination of the waiting period has been granted or such later date as
may be agreed to by Rite Aid on a voluntary basis. Rite Aid has submitted its
responses to the Second Request and certified to the FTC that it was in
substantial compliance with the Second Request as of February 7, 1996. Rite Aid
has voluntarily agreed with the FTC to extend such 10 day waiting period through
February 23, 1996.
    
 
     At any time before or after the Effective Time, notwithstanding that the
waiting period under the HSR Act has expired, the FTC or the Antitrust Division
could take such action under the antitrust laws as it deems necessary or
desirable in the public interest, including seeking to enjoin the consummation
of the Merger or seeking divestiture of substantial assets of Rite Aid or Revco.
At any time before or after the Effective Time, and notwithstanding that the
waiting period under the HSR Act has expired, any state could take such action
under its antitrust law as it deems necessary or desirable in the public
interest. Such action could include seeking to enjoin the consummation of the
Merger or seeking divestiture of substantial assets of Rite Aid or Revco.
Private persons may also seek to take legal action under the antitrust laws
under certain circumstances.
 
     Rite Aid has received requests for information from four state attorneys
general concerning the Merger. Rite Aid is cooperating with such attorneys
general.
 
     Certain Litigation.  On November 30, 1995, a purported class action
entitled Silvert v. Revco D.S., Inc., et al.('Silvert') was filed in the Court
of Chancery of the State of Delaware, New Castle County, on behalf of the class
of all Revco's stockholders. The Silvert complaint named Revco, all of Revco's
directors and Rite Aid as defendants. The Silvert complaint alleges that the
$27.50 per share of Revco Common Stock price offered by Rite Aid in the Offer is
insufficient and that the Offer is unfair to Revco's stockholders and represents
an attempt by the defendants to enrich themselves at the expense of the
plaintiff class. The plaintiff in the Silvert action asserts that defendants
violated their fiduciary duties to Revco's stockholders by allegedly failing
adequately to evaluate Revco as a potential acquisition candidate; to take
adequate steps to enhance Revco's value as an acquisition candidate; and to
create an active and open auction for Revco. The Silvert complaint further
alleges that the option granted to Rite Aid pursuant to the Stock Option
Agreement impedes the maximization of Revco stockholder value. The Silvert
complaint seeks, among other relief, a preliminary and permanent injunction
barring defendants from taking any steps to accomplish the proposed Merger at a
price that is not fair and equitable to the plaintiffs and enjoining any
improper device or transaction which will impede maximization of stockholder
value. The Silvert complaint also seeks unspecified damages for losses suffered
and to be suffered by the plaintiff class as a result of the acts alleged in the
Silvert complaint.
    
     On December 26, 1995, a purported consumer class action entitled Ruth
Brady, et al. v. Rite Aid Corporation, Case No. 1:95 CV 2793 was filed in the
United States District Court for the Northern District of

 
                                       55
<PAGE>

Ohio, Eastern Division. The complaint was filed on behalf of customers of Revco
stores against Rite Aid alleging that Rite Aid's proposed Merger with Revco
violates the federal antitrust laws because the alleged effect of the Merger may
be substantially to lessen competition or it may tend to create a monopoly. The
complaint seeks a preliminary and permanent injunction enjoining Rite Aid from
acquiring Revco, or rescission of the Merger if it is consummated; a preliminary
injunction enjoining Rite Aid from voting any Revco shares or exercising any
influence or control over Revco; and an award of the costs of the litigation,
including attorneys' fees. Rite Aid has filed an answer to the complaint denying
the substantive allegations therein. On December 26, 1995, the plaintiff filed a
Motion For Preliminary Injunction seeking such relief. A hearing relating to
such Motion is expected to be held in the near future.
    
 
     Closing Condition.  The respective obligations of Rite Aid and Revco to
consummate the Merger are subject to the condition that no court, arbitrator or
governmental body, agency or official will have issued any order, decree or
ruling which remains in force and there will not have been any statute, rule or
regulation, restraining, enjoining or prohibiting the consummation of the
Merger. See 'MERGER AGREEMENT--Conditions to the Merger.'
 
APPRAISAL RIGHTS FOR REVCO STOCKHOLDERS
 
     If only shares of Rite Aid Common Stock are issued in the Merger, then
Revco stockholders will not have any appraisal rights. However, in the event (i)
the Alternative Consideration or any Additional Consideration contemplated by
the Merger Agreement is applicable or (ii) Rite Aid elects to pay any Cash
Adjustment Amount, dissenting holders of Revco Common Stock will be entitled to
have the 'fair value' (exclusive of any element of value arising from the
accomplishment or expectation of the Merger) of their shares of Revco Common
Stock at the Effective Time judicially determined and paid to them by complying
with the provisions of Section 262 of the DGCL. Rite Aid stockholders will not
have any appraisal rights in connection with the Merger.
 
RESALES OF RITE AID COMMON STOCK
 
     All shares of Rite Aid Common Stock constituting the Share Issuance will be
freely transferable, except that shares received by any person who may be deemed
to be an 'affiliate' (as used in paragraphs (c) and (d) of Rule 145 under the
Securities Act, including, without limitation, directors and certain executive
officers) of Revco for purposes of such Rule 145 may not be resold except in
transactions permitted by such Rule 145 or as otherwise permitted under the
Securities Act.
 
     Revco has agreed to deliver to Rite Aid a letter identifying, to the best
of Revco's knowledge, all persons who are, at the time of the Revco Special
Meeting, deemed to be 'affiliates' (as used in the preceding paragraph) of Revco
and to use its best efforts to cause each person so identified to deliver to
Rite Aid at least 30 days prior to the Closing Date an agreement, substantially
in the form previously approved by Rite Aid and Revco, providing that such

person will not sell, pledge, transfer or otherwise dispose of any Rite Aid
Common Stock received by such person in exchange for shares of Revco Common
Stock pursuant to the Merger, except pursuant to an effective registration
statement or in compliance with such Rule 145 or another exemption from the
registration requirements of the Securities Act.

                                MERGER AGREEMENT
 
     The following summary of the Merger Agreement and the Merger contained in
this Proxy Statement is not intended to be a complete description of the terms
and conditions thereof and is qualified in its entirety by reference to the full
text thereof, which is incorporated herein by reference and a copy of which is
attached hereto as Annex A. Capitalized terms not otherwise defined herein or in
the following summary shall have the meanings set forth in the Merger Agreement.

 
   
     The Offer.  Pursuant to the Merger Agreement, on December 4, 1995, Sub
commenced the Offer. The Offer has been extended and is presently scheduled to
expire on February 23, 1996. Rite Aid reserves the right to further extend the
Offer.
    
 
     The Merger.  The Merger Agreement provides that, subject to the terms and
conditions thereof, and in accordance with the DGCL, at the Effective Time,
Revco and Sub shall consummate the Merger pursuant to which (i) Sub shall be
merged with and into Revco and the separate corporate existence of Sub shall
thereupon cease, and (ii) Revco shall be the Surviving Corporation and shall
continue to be governed by the laws of the State of Delaware. Pursuant to the
Merger, (x) the Certificate of Incorporation of Revco, as in effect immediately
prior to the Effective Time, shall be the Certificate of Incorporation of the
Surviving Corporation until thereafter amended as provided by law and such
Certificate of Incorporation, and (y) the By-laws of Revco, as in effect
immediately prior to the Effective Time, shall be the By-laws of the Surviving
Corporation until thereafter amended as provided by law, the Certificate of
Incorporation of the Surviving Corporation and such By-laws. The Merger shall
have the effects set forth in the DGCL.
 
     Conversion of Revco Common Stock.  The Merger Agreement provides that each
share of Common Stock, par value $.01 per share, of Sub issued and outstanding
immediately prior to the Effective Time without any other action by Rite Aid,
Sub or Revco, shall, at the Effective Time, be converted into and become one
fully paid and nonassessable share of common stock of the Surviving Corporation.
 
     Each share of Revco Common Stock issued and outstanding immediately prior
to the Effective Time (other than Revco Common Stock owned by Revco as treasury
stock and any Revco Common Stock owned by Rite Aid, Sub or any other direct or
indirect wholly owned subsidiary of Rite Aid and other than Dissenting Revco
Shares, if any) shall, at the Effective Time, by virtue of the Merger and
without any action on the part of the holder thereof, be converted into either
(i) the right to receive a number of duly authorized, validly issued, fully paid
and nonassessable shares of Rite Aid Common Stock determined as set forth below
(the 'Exchange Ratio'); provided that Rite Aid shall not issue more than 1.125
or fewer than .91666 shares of Rite Aid Common Stock per share of Revco Common
Stock, or (ii) if the alternative consideration described below is applicable,
then the right to receive the Alternative Consideration, plus, in each of clause
(i) and (ii) of this sentence, any Additional Consideration.
 
     For purposes hereof, 'Average Rite Aid Share Price' shall mean the average
closing price per share of Rite Aid Common Stock on the NYSE as reported on the
NYSE Composite Tape for fifteen NYSE trading days selected by Rite Aid and Revco
by lot from among the forty NYSE trading days ending on the fifth trading day
immediately preceding the Revco Special Meeting. 'Transaction Price' shall mean
$27.50 per share of Revco Common Stock. The number of shares of Rite Aid Common
Stock into which each share of Revco Common Stock shall be converted in the
Merger shall be determined as follows:
 
          In the event the Average Rite Aid Share Price equals the Transaction
     Price, each Share shall be converted into one share of Rite Aid Common

     Stock.
 
          In the event that the Average Rite Aid Share Price is greater than the
     Transaction Price, each share of Revco Common Stock shall be converted into
     a number of shares of Rite Aid Common Stock (rounded to the nearest one
     one-hundred thousandth) determined by the following formula:

          In the event that the Average Rite Aid Share Price is less than the
     Transaction Price, each share of Revco Common Stock shall be converted, at
     the option of Rite Aid, into either:
 
            (I) a number of shares of Rite Aid Common Stock (rounded to the
            nearest one one-hundred thousandth) determined by the following

            Amount, without any interest thereon, where the Cash Adjustment

                        Cash Adjustment Amount      =      Rite Aid Share Price);

provided however, in no event will the Cash Adjustment Amount be greater than
$2.75 per share of Revco Common Stock.

- ------------------
(1) Represents the number of shares of Rite Aid Common Stock to be issued for
    each share of Revco Common Stock.
 
     All shares of Revco Common Stock that are owned by Revco as treasury stock
and any shares of Revco Common Stock owned by Rite Aid, Sub or any other direct
or indirect wholly owned Subsidiary of Rite Aid shall, at the Effective Time, be
cancelled and retired and shall cease to exist and no Rite Aid Common Stock or
cash, if the Alternative Consideration is applicable, shall be delivered in
exchange therefor.
 
     The Merger Agreement provides that, on and after the Effective Time,
holders of certificates which immediately prior to the Effective Time
represented outstanding shares of Revco Common Stock (the 'Certificates') shall
cease to have any rights as stockholders of Revco, except the right to receive
the consideration set forth therein (other than the Merger Consideration) for
each share of Revco Common Stock held by them or, if applicable, payments due to
holders of Dissenting Revco Shares.
 
     The Merger Agreement provides that in the event that the stockholders of
Rite Aid do not approve the issuance of Rite Aid Common Stock pursuant to the
Merger at the Rite Aid Special Meeting, but all conditions to the Merger are
otherwise satisfied or waived (if permissible), Revco, Rite Aid and Sub shall
nonetheless consummate the Merger and each share of Revco Common Stock issued
and outstanding immediately prior to the Effective Time (other than treasury
shares of Revco Common Stock and shares of Revco Common Stock owned by Rite Aid
and its Subsidiaries) will, at the Effective Time, by virtue of the Merger and
without any action on the part of the holder thereof, be converted into the
right to receive the following Alternative Consideration in a combination of
shares of Rite Aid Common Stock and cash determined as follows:
 
          The number of shares of Rite Aid Common Stock into which each share of
     Revco Common Stock shall be converted in the Merger (the 'Adjusted Exchange
     Ratio') shall equal the Exchange Ratio determined pursuant to the
     applicable formula set forth above (assuming no Cash Adjustment Amount is
     paid) multiplied by a fraction (the 'Adjustment Fraction'), the numerator
     of which is the number of shares of

 
                                       59
<PAGE>
     Rite Aid Common Stock equal to 19.9% of the then outstanding shares of Rite
     Aid Common Stock and the denominator of which is (a) the Exchange Ratio
     multiplied by (b) the aggregate number of outstanding shares of Revco
     Common Stock (other than treasury shares of Revco Common Stock and shares
     of Revco Common Stock owned by Rite Aid and its subsidiaries); and
 
          The amount of cash (the 'Adjusted Alternative Cash Consideration')
     into which each share of Revco Common Stock shall be converted in the
     Merger shall equal the Transaction Price multiplied by (1 minus the
     Adjustment Fraction).
 
     The Merger Agreement provides that in the event the Merger is not
consummated prior to April 29, 1996 and Revco shall not have materially breached
the Merger Agreement (other than by acts caused or permitted by Rite Aid), then
the stockholders of Revco will be entitled to receive interest on the amount of
the Merger Consideration that they receive, from April 29, 1996 until the
earlier of the Effective Time or June 30, 1996, calculated at an annual rate
equal to the prime rate of interest (as announced from time to time by Morgan
Guaranty Trust Company of New York). For purposes of calculating the Merger
Consideration, the Average Rite Aid Share Price, if not otherwise ascertainable
in accordance with the terms of the Merger Agreement, shall be the average price
of Rite Aid Common Stock based on the 15 highest closing prices of Rite Aid
Common Stock since the consummation of the Offer until the earlier of June 30,
1996 or the Effective Time.
 
     In the event Rite Aid and/or Sub, in violation of their obligations under
the Merger Agreement, fails or refuses to consummate the Merger on or prior to
June 30, 1996 and Revco shall not have materially breached the Merger Agreement
(other than by acts caused or permitted by Rite Aid), then, in addition to any
rights or remedies that Revco and its stockholders otherwise have in law or at
equity as a result thereof, the stockholders of Revco will be entitled to
receive interest from June 30, 1996 on the amount of the Merger Consideration
not paid until such Merger Consideration is paid, calculated at the annual rate
of the higher of (i) the prime rate of interest (as announced from time to time
by Morgan Guaranty Trust Company of New York) plus 300 basis points or (ii) the
amount otherwise permitted by law. For purposes of calculating the Merger
Consideration, the Average Rite Aid Share Price, if not otherwise ascertainable
in accordance with the terms of the Merger Agreement, shall be the average price
of Rite Aid Common Stock based on the 15 highest closing prices of Rite Aid
Common Stock since the consummation of the Offer until such Merger Consideration
is paid.
 
     Rite Aid and Sub have covenanted and agreed to consummate the Merger
pursuant to the terms of the Merger Agreement not later than June 30, 1996.
 
     In lieu of any fractional share of Rite Aid Common Stock, Rite Aid shall
pay to each former stockholder of Revco who otherwise would be entitled to
receive a fractional share of Rite Aid Common Stock an amount in cash determined
by multiplying (i) the Average Rite Aid Share Price on the date on which the
Effective Time occurs by (ii) the fractional interest in a share of Rite Aid
Common Stock to which such holder would otherwise be entitled.

 
     Each share of Rite Aid Common Stock issued to holders of Revco Common Stock
in the Merger will be issued together with one associated Right in accordance
with the Rite Aid Rights Agreement.
 
     THE MARKET VALUE OF THE RITE AID COMMON STOCK DURING THE PRICING PERIOD AND
AFTER THE EFFECTIVE TIME WILL, AMONG OTHER THINGS, DEPEND UPON, AND IS EXPECTED
TO FLUCTUATE WITH, THE PERFORMANCE OF RITE AID, CONDITIONS (ECONOMIC OR
OTHERWISE) AFFECTING THE RETAIL DRUGSTORE INDUSTRY, AND MARKET CONDITIONS AND
OTHER FACTORS THAT GENERALLY INFLUENCE PRICES OF SECURITIES.
 
     Treatment of Stock Options.  The Merger Agreement provides that, effective
as of the Effective Time, each Revco Stock Option, will cease to represent a
right to acquire shares of Revco Common Stock and will be converted
automatically into an option to purchase shares of Rite Aid Common Stock in an
amount and at an exercise price determined as provided below (and otherwise
subject to the terms of the Option Plans, and the agreements evidencing grants
thereunder). The number of shares of Rite Aid Common Stock subject to, and the
option price and terms and conditions of, the new option shall be determined in
a manner that preserves both (i) the aggregate gain (or loss) on Revco Stock
Option immediately prior to the Effective Time and (ii) the ratio of the
exercise price per share subject to Revco Stock Option to the fair market value
(determined immediately prior to the Effective Time) per share subject to such
option, provided that any fractional shares of Rite Aid Common Stock resulting
from such determination will be rounded down to the nearest share. The Merger
Agreement also provides that, effective as of the Effective Time, the Surviving
Corporation will assume each Revco Stock Option agreement, each as amended, as
provided therein. The adjustment provided herein with
 
                                       60
<PAGE>
respect to any Revco Stock Options that are 'incentive stock options' (as
defined in Section 422 of the Code) shall be and is intended to be effected in a
manner that is consistent with Section 424(a) of the Code. The duration, vesting
and other terms of the new options will be the same as Revco Stock Options that
they replace, except that all references to Revco shall be deemed to be
references to Rite Aid. In the event that a holder of a Revco Stock Option is
terminated without Cause (as defined in the Merger Agreement) within 12 months
of the Effective Time, then such holder's new option will become 100%
exercisable as of such date of termination.
 
     The Merger Agreement further provides that, notwithstanding the immediately
preceding paragraph, outstanding vested options under the 1992 Long Term
Incentive Plan ('LTIP') held by Covered Executives (as defined in the Merger
Agreement), including options that become vested in connection with a 'Change in
Control' under the terms of existing award agreements under the LTIP, will,
effective as of the Effective Time become exercisable under a cashless exercise
procedure made available by Revco (subject to applicable law and any
administrative procedures and policies deemed appropriate by Revco). Individuals
subject to Section 16 of the Exchange Act will be provided with a cash
compensation arrangement providing such individuals with the opportunity to
receive a cash payment approximating the benefits that would be deprived by
reason of Section 16 of the Exchange Act.
 

     The Merger Agreement provides that, effective as of the Effective Time, the
Option Plans will terminate and the provisions in any other plan, program,
agreement or arrangement, providing for the issuance or grant of any other
interest in respect of the capital stock of Revco or any of its subsidiaries
will be deleted. Furthermore, Revco will take all actions necessary to ensure
that following the Effective Time, no holder of Revco Stock Options or any
participant in the Option Plans or any other plans, programs, agreements or
arrangements will have any right thereunder to acquire any equity securities of
Revco, the Surviving Corporation or any subsidiary of either of the foregoing.
 
     Directors and Officers.  Pursuant to the Merger Agreement, promptly upon
the acceptance for payment of any shares of Revco Common Stock by Rite Aid or
any of its Subsidiaries pursuant to the Offer, Rite Aid shall be entitled to
designate such number of directors, rounded up to the next whole number, on
Revco Board as is equal to the product of the total number of directors on such
Board (giving effect to the directors designated by Rite Aid pursuant to this
sentence) multiplied by the percentage that the aggregate number of shares of
Revco Common Stock beneficially owned by Sub, Rite Aid and any of their
affiliates bears to the total number of shares of Revco Common Stock then
outstanding. Revco shall, upon request of Rite Aid, use its best efforts
promptly either to increase the size of its Board of Directors or, at Revco's
election, secure the resignations of such number of its incumbent directors as
is necessary to enable Rite Aid's designees to be so elected to Revco's Board,
and shall cause Rite Aid's designees to be so elected. At such time, Revco shall
also cause persons designated by Rite Aid to constitute the same percentage
(rounded up to the next whole number) as is on the Revco Board of (i) each
committee of the Revco Board, (ii) each board of directors (or similar body) of
each Subsidiary of Revco and (iii) each committee (or similar body) of each such
board, in each case only to the extent permitted by applicable law or the rules
of any stock exchange on which Revco Common Stock is listed. Notwithstanding the
foregoing, until the Effective Time, each of Rite Aid, Sub and Revco shall use
its best efforts to retain as a member of Revco's Board at least two directors
who are directors of Revco on the date of the Merger Agreement (the 'Revco
Continuing Directors'); provided, that subsequent to the purchase of and payment
for shares of Revco Common Stock pursuant to the Offer, Rite Aid shall always
have its designees represent at least a majority of the entire Board of
Directors. In the event of a vacancy on the Revco Board resulting from the
resignation or death of any Revco Continuing Director, such vacancy shall be
filled by the remaining Revco Continuing Directors, or if there are no remaining
Revco Continuing Directors, by the designees of the Stockholder. Revco's
obligations pursuant to this paragraph are subject to Section 14(f) of the
Exchange Act and Rule 14f-1 promulgated thereunder. Promptly following the
expiration of the Offer, Rite Aid intends to designate certain of its designees
(the 'Rite Aid Designees') as directors to the Revco Board and certain incumbent
members of the Revco Board are expected to resign; as a result, the Rite Aid
Designees will represent a majority of the directors on the Revco Board
following consummation of the Offer.
 
     Interim Operations.  In the Merger Agreement, Revco has covenanted and
agreed that: (i) except as expressly provided in the Merger Agreement, (ii)
during the period prior to the consummation of the Offer, except with the prior
written consent of Rite Aid, (iii) during the period following the consummation
of the Offer and prior to the Effective Time, except with the authorization of
the Revco Board, including the affirmative vote of a majority of the Revco

Continuing Directors, and (iv) during the period following consummation of the
Offer
 
                                       61
<PAGE>
and prior to the Effective Time, except for prepayments by Rite Aid of
indebtedness of Revco and the advancement of funds by Rite Aid to Revco on the
terms and conditions, and at the interest rate, and for the purposes for which
borrowing may be made, under Revco's existing credit facility: (a) the business
of Revco and its Subsidiaries shall be conducted only in the ordinary course of
business consistent with past practice and, to the extent consistent therewith,
each of Revco and its Subsidiaries will use its best efforts to preserve its
business organization intact and maintain its existing relations with customers,
suppliers, employees, creditors and business partners; (b) Revco will not,
directly or indirectly, split, combine or reclassify the outstanding shares of
Revco Common Stock, or any outstanding capital stock of any of the Subsidiaries
of Revco; (c) neither Revco nor any of its Subsidiaries will: (I) amend its
certificate of incorporation or by-laws or similar organizational documents;
(II) declare, set aside or pay any dividend or other distribution payable in
cash, stock or property with respect to its capital stock other than dividends
paid by Revco's Subsidiaries to Revco or its Subsidiaries; (III) issue, sell,
transfer, pledge, dispose of or encumber any additional shares of, or securities
convertible into or exchangeable for, or options, warrants, calls, commitments
or rights of any kind to acquire, any shares of capital stock of any class of
Revco or its Subsidiaries, other than issuances pursuant to exercise of
stock-based awards or options outstanding on the date thereof; (IV) transfer,
lease, license, sell, mortgage, pledge, dispose of, or encumber any material
assets other than (x) in the ordinary course of business consistent with past
practice or (y) pursuant to existing agreements previously disclosed by Revco in
writing to Rite Aid and Sub; or (V) redeem, purchase or otherwise acquire
directly or indirectly any of its capital stock; (d) neither Revco nor any of
its Subsidiaries shall: (I) except as otherwise provided in the Merger
Agreement, and except for normal, regularly scheduled increases for nonofficer
employees consistent with past practice or pursuant to the terms of existing
collective bargaining agreements, grant any increase in the compensation payable
or to become payable by Revco or any of its Subsidiaries to any officer or
employee (including through any new award made under, or the exercise of any
discretion under, any Benefit Plan); (II) adopt any new, or amend or otherwise
increase, or accelerate the payment or vesting of the amounts payable or to
become payable under any existing, bonus, incentive compensation, deferred
compensation, severance, profit sharing, stock option, stock purchase,
insurance, pension, retirement or other employee benefit plan agreement or
arrangement; (III) enter into any, or amend any existing,employment or severance
agreement with or, grant any severance or termination pay to any officer,
director, employee or consultant of Revco or any of its Subsidiaries; or (IV)

provide funding for non-tax-qualified employee benefits or compensation; or (V)
provide any severance program to any Subsidiary which does not have a severance
program as of the date of the Merger Agreement; (e) neither Revco nor any of its
Subsidiaries shall modify, amend or terminate any of the Revco Agreements or
waive, release or assign any material rights or claims, except in the ordinary
course of business consistent with past practice; (f) neither Revco nor any of
its Subsidiaries will permit any material insurance policy naming it as a
beneficiary or a loss payable payee to be cancelled or terminated without notice

to Rite Aid, except in the ordinary course of business consistent with past
practice; (g) except as previously disclosed by Revco in writing to Rite Aid and
Sub, neither Revco nor any of its Subsidiaries will: (I) incur or assume any
debt except for borrowings under existing credit facilities in the ordinary
course consistent with past practice; (II) assume, guarantee, endorse or
otherwise become liable or responsible (whether directly, contingently or
otherwise) for the obligations of any other person, except in the ordinary
course of business consistent with past practice; (III) make any loans, advances
or capital contributions to, or investments in, any other person (other than to
wholly owned Subsidiaries of Revco or customary loans or advances to employees
in accordance with past practice); or (IV) enter into any material commitment
(including, but not limited to, any leases, capital expenditure or purchase of
assets) other than purchases of inventory in the ordinary course of business
consistent with past practice; (h) neither Revco nor any of its Subsidiaries
shall change any of the accounting principles used by it unless required by

reserved against in the consolidated financial statements (or the notes thereto)
of Revco and its consolidated Subsidiaries, (II) incurred in the ordinary course
of business consistent with past practice or (III) which are legally required to
be paid, discharged or satisfied; (j) neither Revco nor any of its Subsidiaries
will adopt a plan of complete or partial liquidation, dissolution, merger,
consolidation, restructuring, recapitalization or other material reorganization
of Revco or any of its Subsidiaries or any agreement relating to a Takeover

<PAGE>
in the Merger Agreement inaccurate in any respect at, or as of any time prior
to, the Effective Time; (l) neither Revco nor any of its Subsidiaries will
engage in any transaction with, or enter into any agreement, arrangement, or

Revco will cooperate with Rite Aid, if Rite Aid so requests, to effect a
defeasance of, and/or a repurchase by means of a debt tender offer (together
with a solicitation of consents to eliminate the restrictive covenants) of the
Debt Offers, provided that any funds and all related out-of-pocket transaction
expenses necessary to effect any such defeasance or repurchase shall be provided
and borne by Rite Aid, without any right of reimbursement. The Merger Agreement
also provides that Revco and Rite Aid will cooperate to effect such defeasance
and/or repurchase in a manner which takes into account all relevant tax,
accounting, corporate, structural, contractual and similar issues. Rite Aid
presently expects that it will commence the Debt Offers after the consummation
of the Offer.
    
 
     No Solicitation.  Pursuant to the Merger Agreement, Revco (and its
Subsidiaries, and affiliates over which it exercises control) will not, and
Revco (and its Subsidiaries, and affiliates over which it exercises control)
will use their best efforts to ensure that their respective officers, directors,
employees, investment bankers, attorneys, accountants and other agents do not,
directly or indirectly: (i) initiate, solicit or encourage, or take any action
to facilitate the making of, any offer or proposal which constitutes or is
reasonably likely to lead to any Takeover Proposal (as defined below) of Revco
or any Subsidiary or an inquiry with respect thereto, or, (ii) in the event of
an unsolicited Takeover Proposal for Revco or any Subsidiary or affiliate of
Revco, engage in negotiations or discussions with, or provide any information or
data to, any corporation, partnership, person or other entity or group (other
than Rite Aid, any of its affiliates or representatives) (each, a 'Person')
relating to any Takeover Proposal, except in the case of clause (ii) above to
the extent that (x) the Takeover Proposal is a bona fide written proposal
submitted to Revco's Board of Directors and (y) the Revco Board determines,
after having received the oral or written opinion of outside legal counsel to
Revco, that the failure to engage in such negotiations or discussions or provide
such information would result in a breach of the Board of Directors' fiduciary
duties under applicable law. Revco has agreed to notify Rite Aid and Sub orally
and in writing of any such offers, proposals, inquiries or Takeover Proposals
(including, without limitation, the material terms and conditions thereof and
the identity of the Person making it), within 24 hours of the receipt thereof,
and shall thereafter inform Rite Aid on a reasonable basis of the status and
content of any discussions or negotiations with such a third party, including
any material changes to the terms and conditions thereof. The Merger Agreement
also provides that Revco shall, and shall cause its Subsidiaries and affiliates
over which it exercises control, and will use best efforts to ensure their
respective officers, directors, employees, investment bankers, attorneys,
accountants and other agents to immediately cease and cause to be terminated all
discussions and negotiations that have taken place prior to the date of the
Merger Agreement, if any, with any parties conducted theretofore with respect to
any Takeover Proposal relating to Revco. The Merger Agreement provides that
nothing contained in this paragraph will prohibit Revco or the Revco Board from

taking and disclosing to its stockholders a position with respect to a tender
offer by a third party pursuant to Rules 14d-9 and 14e-2(a) promulgated under
the Exchange Act or making such disclosure as may be required by applicable law.
 
                                       63

     As used in the Merger Agreement and herein, 'Takeover Proposal' when used
in connection with any Person shall mean any tender or exchange offer involving
the capital stock of such Person, any proposal for a merger, consolidation or
other business combination involving such Person or any Subsidiary of such
Person, any proposal or offer to acquire in any manner a substantial equity
interest in, or a substantial portion of the business or assets of, such Person
or any Subsidiary of such Person, any proposal or offer with respect to any
recapitalization or restructuring with respect to such Person or any Subsidiary
of such Person or any proposal or offer with respect to any other transaction
similar to any of the foregoing with respect to such Person or any Subsidiary of
such Person other than pursuant to the transactions to be effected pursuant to
the Merger Agreement.
 
     Directors' and Officers' Insurance and Indemnification.  In the Merger
Agreement, Rite Aid agreed that at all times after the Effective Time, it will
cause the Surviving Corporation and its Subsidiaries to indemnify, each person
who is now, or has been at any time prior to the date of the Merger Agreement,
an employee, agent, director or officer of Revco or of any of Revco's
Subsidiaries, successors and assigns (individually an 'Indemnified Party' and
collectively the 'Indemnified Parties'), to the fullest extent permitted by law,
with respect to any claim, liability, loss, damage, judgment, fine, penalty,
amount paid in settlement or compromise, cost or expense, including reasonable
fees and expenses of legal counsel, (whenever asserted or claimed) ('Indemnified
Liability') based in whole or in part on, or arising in whole or in part out of,
any matter existing or occurring at or prior to the Effective Time whether
commenced, asserted or claimed before or after the Effective Time, including
liability arising under the Securities Act, the Exchange Act or state law. The
Merger Agreement provides that Rite Aid will, and will cause the Surviving
Corporation to, maintain in effect for not less than four years after the
Effective Time the current policies of directors' and officers' liability
insurance maintained by Revco and its Subsidiaries on the date of the Merger
Agreement (provided that Rite Aid may substitute therefor policies having at
least the same coverage and containing terms and conditions which are no less
advantageous to the persons currently covered by such policies as insured) with
respect to matters existing or occurring at or prior to the Effective Time;
provided, however, that if the aggregate annual premiums for such insurance
during such period shall exceed 200% of the per annum rate of the aggregate
premium currently paid by Revco and its Subsidiaries for such insurance on the
date of the Merger Agreement, then Rite Aid will cause the Surviving Corporation
to, and the Surviving Corporation will, provide the maximum coverage that will
then be available at an annual premium equal to 200% of such rate. The Merger
Agreement provides that Rite Aid shall pay all expenses (including fees and
expenses of counsel) that may be incurred by any Indemnified Party in
successfully enforcing the indemnity or other obligations under this paragraph.
The rights under this paragraph are in addition to rights that an Indemnified
Party may have under the Certificate of Incorporation, By-laws, other similar
organizational documents of Revco or any of its Subsidiaries or the DGCL. The
Merger Agreement also provides that the rights under this paragraph shall

survive consummation of the Merger and are expressly intended to benefit each
Indemnified Party. Rite Aid will cause the Surviving Corporation and any of its
Subsidiaries (or their successors) to keep in effect the provisions of its
Certificate of Incorporation or By-laws or similar organizational documents
providing for indemnification to the fullest extent provided by law.
 
     Employee Benefits and Employee Matters.  Pursuant to the Merger Agreement,
Rite Aid has agreed that, effective as of the Effective Time, Revco will provide
to employees of Revco certain payments and benefits, as described below.
 
     As soon as practicable following the earlier of (A) the Effective Time and
(B) the end of Revco's 1996 fiscal year, Revco will pay, pursuant to the terms
of Revco's Economic Value Added Incentive Plan (the 'EVA Plan') as modified by
the terms of the Merger Agreement, bonuses for fiscal year 1996, calculated
based on Revco's financial results as of February 10, 1996, and annualized to
equal a bonus for a 12-month period.
 
     With respect to the Covered Executives, effective as soon as practicable
following the Effective Time (or if later, the date of termination of employment
of the Covered Executive), Revco will pay to each Covered Executive severance
payments (the 'Severance Payments'), on a bi-weekly basis or at such other
intervals as are consistent with Rite Aid's executive payroll practices, based
on one of the two formulae set forth below, pursuant to elections made by each
Covered Executive prior to the Effective Time:
 
          (A) Severance Payments equal to, on an annualized basis, 'Base Pay'
     (as defined below), continuing for a period of three years with respect to
     Covered Executives who are listed as Group A Executives on a schedule to
     the Merger Agreement and for a period of 18 months with respect to Covered
     Executives listed
 
                                       64
<PAGE>
     as Group B Executives on a schedule to the Merger Agreement. For purposes
     of this provision, 'Base Pay' means the highest base pay paid to the
     Covered Executive during any one of the 1994, 1995 or 1996 fiscal years,
     provided that the base pay for the 1996 fiscal year will be calculated on
     an annualized basis; or
 
          (B) Severance Payments equal to, on an annualized basis, 'Base Plus
     Bonus Pay' (as defined below), continuing for a period of two years with
     respect to Group A Executives, and for a period of one year with respect to
     Group B Executives. For purposes of this provision 'Base Plus Bonus Pay'
     means Base Pay plus the amount that would have been paid to the executive
     under the EVA Plan for fiscal year 1995 as the targeted bonus (the '1995
     Target Bonus').
 
     In lieu of the Severance Payments described in clauses (A) and (B) above,
Messrs. Hoven and James P. Mastrian will receive Severance Payments, continuing
for three years, equal to, on an annualized basis, Base Plus Bonus Pay.
 
     The period during which a Covered Executive continues to receive Severance
Payments is hereinafter referred to as the 'Severance Period' for such Covered
Executive.

 
     During the Severance Period, each Covered Executive will continue to
receive, at Revco's expense, continuation of benefits described in such Covered
Executive's employment agreement with Revco on terms at least as favorable to
the Covered Executive as is currently in effect, which benefits may be provided
under benefit plans and programs maintained by Rite Aid; provided, however, that
to the extent any such Covered Executive receives comparable benefits from, and
at the expense of, a subsequent employer, such benefits from Revco will cease.
 
     Notwithstanding anything in the Merger Agreement to the contrary, the
Severance Payments described in clauses (A) or (B) above will be paid to a
Covered Executive only if such Covered Executive is actively employed by Revco
immediately prior to the Effective Time.
 
     In the event that a Covered Executive that continues employment with Revco
following the Effective Time is terminated prior to the expiration of the
Severance Period that would have applied had such Covered Executive been
terminated effective as of the Effective Time, then such Covered Executive will
be entitled to receive the Severance Payments described above.
 
     Each employee, other than any Covered Executive, of Revco who is covered by
Revco's severance pay plan as in effect on November 1, 1995 (each, a
'Severance-Eligible Employee') and who is employed by Revco immediately prior to
the Effective Time and terminated for other than 'Cause,' as defined below,
within 12 months following the Effective Time, will be entitled to receive
bi-weekly severance payments, consistent with Rite Aid's payroll practices, for
a six-month period commencing on such Severance-Eligible Employee's date of
termination of employment, equal to, on an annualized basis, such
Severance-Eligible Employee's Base Pay; provided, however, that such payments
will be reduced (but not below zero), by the amount of compensation such
Severance-Eligible Employee receives from a subsequent employer to the extent
that such Severance-Eligible Employee is employed during such six-month period.
 
     For purposes of the Merger Agreement, 'Cause' will mean the conviction of
an employee or executive (as the case may be) for the commission of a felony,
including the entry of a guilty or nolo contendere plea, any willful, grossly
negligent or fraudulent action or inaction by an employee or executive, as the
case may be, or the employee's or executive's willful and continued failure to
substantially perform an employee's or executive's assigned duties.
 
     Each Revco employee who is (A) covered by Revco's Supplemental Executive
Retirement Plan ('SERP') and (B) actively employed by Revco, in either case,
immediately prior to the Effective Time (each, a 'SERP Executive') will be
eligible to receive benefits under the SERP based on the terms of the SERP, as
modified by the terms of the Merger Agreement. For each SERP Executive (i) the
amount of service taken into account for purposes of calculating benefits and
vesting under the SERP will be equal to the SERP Executive's service with Revco
prior to the Effective Time plus the Covered Executive's Severance Period, if
any, and (ii) compensation for each SERP Executive for purposes of the SERP will
include one-half of the 1995 Target Bonus for such SERP Executive.
 
     With respect to the Group A Executives, Revco will provide such executives
with a cash gross-up payment to make such executives whole for the excise taxes
imposed on all benefits and other amounts paid or payable to such executive on

account of the transactions contemplated by the Merger Agreement as a result of
the
 
                                       65
<PAGE>
application of Sections 280G and 4999 of the Code. With respect to all other
employees of Revco who are entitled to benefits and other amounts paid or
payable to such executive on account of the transactions contemplated by the
Merger Agreement as a result of the application of Sections 280G and 4999 of the
Code, Revco shall not be obligated to pay or provide to any such employee any
payments or benefits to the extent that such payments or benefits would
constitute a 'parachute payment' within the meaning of Section 280G(b)(2)(A) of
the Code.
 
     Revco will amend Revco's Employee Stock Purchase Plan to provide that the
option period that is in effect as of November 29, 1995 will cease as soon as
practicable thereafter.
 
     Revco will provide outplacement services from a recognized outplacement
provider selected by Rite Aid to all employees of Revco as of the Effective Time
who were based in Twinsburg, Ohio as of the Effective Time, and are terminated
without Cause within one year of the Effective Time.
 
     In addition, pursuant to the Merger Agreement, employees of Revco who
continue to be employed by Revco as of the Effective Time will receive employee
benefits comparable to those benefits provided to similarly situated employees
of Rite Aid. In addition, with respect to medical benefits provided to
continuing employees as of the Effective Time, waiting periods and pre-existing
condition requirements under the plans covering the continuing employees will be
waived, and these employees will be given credit for any co-payments and
deductibles actually paid by such employees under Revco's medical plans during
the calendar year in which the Closing occurs. Finally, service with Revco will
be recognized for purposes of eligibility under Rite Aid's welfare plans as well
as for purposes of Rite Aid's programs or policies for vacation pay and sick
pay.
 
     Confidentiality Agreement.  Pursuant to the Confidentiality Agreement,
dated as of August 17, 1995, between Rite Aid and Revco (the 'Confidentiality
Agreement'), Rite Aid has agreed, among other things, to keep confidential
certain non-public confidential or proprietary information of Revco furnished to
Rite Aid by or on behalf of Revco. The Confidentiality Agreement provides that
for a period of eighteen months from the date of the Confidentiality Agreement,
except with respect to a business combination with Revco or as otherwise
specifically authorized in writing by Revco, neither Rite Aid nor any of its
directors, officers, employees, agents, advisors (including, without limitation,
financial advisors, counsel and accountants), affiliates or controlling persons
(collectively, the 'Rite Aid Representatives') will, propose or publicly
announce or otherwise disclose an intent to propose, or enter into or agree to
enter into, singly or with any other person or directly or indirectly, (i) any
form of business combination,acquisition or other transaction relating to Revco
or any affiliate thereof, or (ii) any form of restructuring, recapitalization or
similar transaction with respect to Revco or any such affiliate, nor except as
aforesaid during such period will Rite Aid or any such Representative as a
principal (1) acquire, or offer, propose or agree to acquire, by purchase or

otherwise, any securities of Revco, any direct or indirect options or other
rights to acquire any such securities ('Revco Securities'), (2) make, or in any
way participate in, any solicitation of proxies with respect to any Revco
Securities (including by the execution of action by written consent), become a
participant in any election contest with respect to Revco, seek to influence any
person with respect to any Revco Securities or demand a copy of Revco's list of
its stockholders or other books and records relating to holders of Revco
Securities, (3) participate in or encourage the formation of any partnership,
syndicate or other group which owns or seeks or offers to acquire beneficial
ownership of any Revco Securities or which seeks to affect control of Revco or
for the purpose of circumventing any provision of the Confidentiality Agreement
or (4) otherwise act, alone or in concert with others (including by providing
financing for another person), to seek or to offer to control or influence, in
any manner, the management, the Revco Board or policies or operations of Revco.
 
     The Merger Agreement provides that any provision in the Confidentiality
Agreement which in any manner limits, restricts or prohibits the voting or
acquisition of shares of Revco Common Stock by Rite Aid or any of its affiliates
or the representation of Rite Aid's designees on the Revco Board or which in any
manner would be inconsistent with the Merger Agreement, the Stock Option
Agreement or the Stockholder Agreement or the transactions contemplated thereby
terminated as of the date of the Merger Agreement. The Merger Agreement further
provides that Revco will not take any action that would impede, bar, restrict or
otherwise interfere in any manner with Rite Aid's rights under the Stockholder
Agreement or the Stock Option Agreement, including, without limitation, Rite
Aid's right to exercise the Stock Option.
 
     Representations and Warranties.  In the Merger Agreement, Revco has made
customary representations and warranties to Rite Aid and Sub with respect to,
among other things, its organization, capitalization, corporate
 
                                       66

     Tender of Shares of Revco Common Stock.  Immediately after the execution of
the Merger Agreement, Rite Aid, Sub and the Stockholder entered into the
Stockholder Agreement. Upon the terms and subject to the conditions of such
agreement, the Stockholder has agreed to validly tender (or cause the record
owner of such shares of Revco Common Stock to tender), and not to withdraw,
pursuant to and in accordance with the terms of the Offer, not later than prior
to the expiration of the Offer, 13,102,288 shares of Revco Common Stock (and

the conversion or exchange of convertible or exchangeable securities, or by
means of purchase, dividend, distribution, gift, bequest, inheritance or as a

     Voting of Revco Common Stock.  The Stockholder Agreement provides that
during the period commencing on the date of the Stockholder Agreement and
continuing until the first to occur of (i) the Effective Time or (ii)
termination of the Merger Agreement in accordance with its terms, at any meeting
(whether annual or special and whether or not an adjourned or postponed meeting)
of Revco's stockholders, however called, or in connection with any written
consent of the stockholders of Revco, the Stockholder will vote (or cause to be

Offer, the Merger and the transactions contemplated by the Stockholder Agreement
and the Merger Agreement. The Stockholder Agreement further provides that the
Stockholder will not enter into any agreement or understanding with any person
or entity the effect of which would be inconsistent or violative of the
provisions and agreements described in the above paragraph.
 
     Stockholder Covenant.  The Stockholder Agreement provides that, except as
contemplated by the Stockholder Agreement, the Stockholder shall not for a
period of six months following the termination of the Stockholder Agreement

option or right to purchase or acquire any or all of the Stockholder Shares
other than sales made in open market transactions; (ii) agrees or covenants to
vote or to grant a proxy to vote any or all of the Stockholder Shares held of
record or Beneficially Owned by the Stockholder, at any meeting (whether annual

of shares of Revco Common Stock, however called, or in connection with any
written consent of the holders of shares of Revco Common Stock; or (iii) agrees
or covenants to tender any or all of the Stockholder Shares held of record or
 
                                       69

<PAGE>
Beneficially Owned by the Stockholder into any tender offer or exchange offer
relating to the Stockholder Shares.
 
     No Solicitation.  The Stockholder Agreement provides that the Stockholder
will not, and will cause its affiliates and officers, directors, employees,
partners, investment bankers, attorneys, accountants and other agents and
representatives of the Stockholder and such affiliates (such affiliates,
officers, directors, employees, partners, investment bankers, attorneys,
accountants, agents and representatives of any Person are hereinafter
collectively referred to as the 'Representatives' of such Person) not to,
directly or indirectly (i) initiate, solicit or encourage, or take any action to
facilitate the making of, any offer or proposal which constitutes or is
reasonably likely to lead to any Takeover Proposal of Revco or any affiliate or
any inquiry with respect thereto, or (ii) in the event of an unsolicited
Takeover Proposal for Revco or any affiliate of Revco, engage in negotiations or
discussions with, or provide any information or data to, any Person (other than
Rite Aid, any of its affiliates or representatives) relating to any Takeover
Proposal. Notwithstanding the restrictions set forth in this paragraph, any
person who is an officer or director of Revco may exercise his fiduciary duties
in his capacity as a director or officer of Revco consistent with the terms of
the Merger Agreement.
 
     The Stockholder Agreement also provides that the Stockholder notify Rite
Aid and Sub orally and in writing of any such offers, proposals, or inquiries
relating to the purchase or acquisition by any Person of the Stockholder Shares
(including, without limitation, the terms and conditions thereof and the
identity of the Person making it), within 24 hours of the receipt thereof. The
Stockholder has also agreed to, and to cause its Representatives to, immediately
cease and cause to be terminated any and all existing activities, discussions or
negotiations, if any, with any parties conducted theretofore with respect to any
Takeover Proposal relating to Revco, other than discussions or negotiations with
Rite Aid and its affiliates.
 
     Distribution of Shares of Rite Aid Common Stock.  The Stockholder Agreement
provides that upon the consummation of the Merger, the Stockholder shall within
90 days thereafter either distribute the shares of Rite Aid Common Stock to each
of the limited partners of Zell/Chilmark Fund, L.P. or sell or otherwise dispose
of such shares of Rite Aid Common Stock, in each case in accordance with the
governing documents thereto and applicable law; provided that no such sale or
other disposition shall be made if immediately following such sale or other
disposition the acquiror of such Rite Aid Common Stock, together with the
acquiror's affiliates and any members of a group of which the acquiror is a
party, would Beneficially Own in the aggregate 4.9% or more of the shares of
Rite Aid Common Stock then outstanding.
 
     Restriction on Transfer, Proxies and Non-Interference.  The Stockholder
Agreement also provides that, except as otherwise provided in the Stockholder
Agreement, the Stockholder will not, directly or indirectly: (i) offer for sale,
sell, transfer, tender, pledge, encumber, assign or otherwise dispose of, or

respect to or consent to the offer for sale, transfer, tender, pledge,
encumbrance, assignment or other disposition of, any or all of the Stockholder
Shares or any interest therein; (ii) grant any proxies or powers of attorney,

deposit the Stockholder Shares into a voting trust or enter into a voting
agreement with respect to the Stockholder Shares; or (iii) take any action that
would make any representation or warranty of the Stockholder contained in the
Stockholder Agreement untrue or incorrect or would result in a breach by the
Stockholder of its obligations under the Stockholder Agreement or a breach by
Revco of its obligations under the Merger Agreement.
 
     Termination.  Except as otherwise provided therein, the covenants and
agreements contained in the Stockholder Agreement with respect to the
Stockholder Shares shall terminate upon the earlier of (i) the consummation of
the Merger and (ii) the termination of the Merger Agreement in accordance with
its terms except, that the covenant and agreement set forth in the Stockholder
Covenant described in the fifth preceding paragraph shall survive for six months
after such termination (other than a termination as a result of a breach by Rite
Aid or Sub).
 
                             STOCK OPTION AGREEMENT
 
     The following summary of the material terms of the Stock Option Agreement
contained in this Proxy Statement is not intended to be a complete description
of the terms and conditions thereof and is qualified in its entirety by
reference to the full text thereof which is incorporated herein by reference and
a copy of which is attached hereto as Annex E. Capitalized terms not otherwise
defined herein or in the following summary shall have the meanings set forth in
the Stock Option Agreement.
 
                                       70
<PAGE>
     Grant of Stock Option.  The Stock Option Agreement provides for the grant
by Revco to Rite Aid of an unconditional, irrevocable option (a 'Stock Option')
to purchase up to 13,251,010 fully paid and nonassessable shares of Revco Common
Stock at a purchase price of $27.50 per share of Revco Common Stock (the 'Option
Purchase Price'), or such other number of shares of Revco Common Stock as equals
19.9% of Revco's issued and outstanding shares of Revco Common Stock at the time
of exercise of the Stock Option; provided that in no event shall the number of
shares of Revco Common Stock for which the Stock Option is exercisable exceed
19.9% of the shares of Revco Common Stock issued and outstanding at the time of
exercise of the Stock Option (the 'Option Shares').
 
     Exercise of Stock Option.  The Stock Option Agreement also provides that
upon (x) the occurrence of a Trigger Event, or (y) the occurrence of a tender or
exchange offer for some or all of the shares of Revco Common Stock or if a
proposal for a Takeover Proposal shall have been publicly proposed to be made or
shall have been made by another person or entity, the Stock Option shall become
immediately exercisable, in whole or in part, and remain exercisable in whole or
in part until the later of (i) the date which is six months after the date the
Stock Option first became exercisable and (ii) the fifth business day following
expiration or termination of any applicable waiting period under the HSR Act
(the 'Option Period').
 
     Sale of Option Shares.  The Stock Option Agreement also provides that if,
at any time following the exercise of the Stock Option, Rite Aid will either (i)
transfer, sell or otherwise dispose of any or all of the Option Shares,
including by means of tender or exchange of any or all of the Option Shares

pursuant to a tender or exchange offer involving the capital stock of Revco, or
(ii) convert such Option Shares into cash, capital stock, other securities or
any other consideration of any third party in a merger, any recapitalization or
restructuring or similar business combination transaction (a 'Business
Combination Transaction'), Rite Aid will pay to Revco within five days the
amount equal to the Profit (as defined below) Rite Aid will receive, if any,
pursuant to such Disposition or Business Combination Transaction. 'Profit,' for
purposes of this paragraph, will equal (i) the product of (a) the number of
Option Shares Rite Aid transfers, sells, tenders, exchanges or otherwise
disposes of pursuant to a Disposition or a Business Combination Transaction
multiplied by (b) the excess of the per Share consideration received by Rite Aid
pursuant to such Disposition or Business Combination Transaction, valuing any
non-cash consideration at its fair market value on the date of such consummation
(not including any increase in such aggregate per Share consideration after the
date thereof), over the Option Purchase Price. For purposes thereof, the fair
market value of any non-cash consideration shall be the closing price or the
last sale price, or, in case no such sale takes place on the day of consummation
of such Business Combination Transaction, the average of the closing bid and
asked prices, in either case as reported in the principal consolidated
transaction reporting system with respect to securities listed or admitted to
trading on the principal national securities exchange on which such
consideration is listed or admitted to trading or, if such consideration is not
listed or admitted to trading on any national securities exchange, the last
quoted price or, if not so quoted, the average of the high bid and low asked
prices in the over-the-counter market, as reported by the National Association
of Securities Dealers, Inc. Automated Quotation System or such other system then
in use, or, if not so determinable, the fair value of such consideration on such
date will be determined in good faith by the Rite Aid Board.
 
     Adjustment Upon Changes in Capitalization.  The Stock Option Agreement
provides that in the event of any change in shares of Revco Common Stock by
reason of stock dividends, split-ups, recapitalizations, combinations, exchanges
of shares or the like, the type and number of shares of Revco Common Stock
subject to the Stock Option and the Purchase Price shall be appropriately
adjusted and proper provision shall be made so that, in the event that any
additional shares of Revco Common Stock are issued or otherwise become
outstanding as a result of any such change after the date of the Stock Option
Agreement (other than pursuant to the Stock Option Agreement), the number of
shares of Revco Common Stock subject to the Stock Option shall be adjusted so
that, after such issuance and together with shares of Revco Common Stock
previously issued pursuant to the exercise of the Stock Option (as adjusted on
account of any of the foregoing change in shares of Revco Common Stock), it
equals 19.9% of the number of shares of Revco Common Stock then issued and
outstanding.
 
     Termination.  The Stock Option Agreement will terminate, except as
otherwise provided therein, upon the earlier of (i) the consummation of the
Merger and (ii) the expiration of the Option Period.

           UNAUDITED PRO FORMA CONDENSED CONSOLIDATED FINANCIAL DATA
 

     The following Pro Forma Condensed Consolidated Statements of Operations for
the fifty-three weeks ended March 4, 1995 and the thirty-nine weeks ended
December 2, 1995 present pro forma operating results for Rite Aid as if the
Merger had occurred as of the beginning of the periods presented. The following
Pro Forma Condensed Consolidated Balance Sheet presents the pro forma financial
condition of Rite Aid as if the Merger had occurred as of December 2, 1995. The
purchase price of Revco was determined based on arm's-length negotiations
between the parties to the Merger Agreement. The excess of the purchase price of
Revco over the net identifiable assets and liabilities of Revco is reported as
goodwill. The carrying values of Revco's net assets are assumed to equal their
fair values for purposes of these pro forma financial statements, unless
indicated otherwise in the Notes to Unaudited Pro Forma Condensed Consolidated
Financial Data. These values are subject to revision following the results of
any appraisals after consummation of the Merger and related transactions.
However, management does not believe that the results of any such appraisals
will yield materially different values from the carrying values. The Pro Forma
Condensed Consolidated Balance Sheet and Statements of Operations were prepared
assuming consummation of:
 
          (i) the Merger, which is accounted for under the purchase method of
     accounting;
 
          (ii) the Credit Facility; and
 
          (iii) the refinancing of $720 million of outstanding Revco debt.
 
     The pro forma adjustments are described in the accompanying notes and
represent Rite Aid's preliminary determination of the necessary adjustments. The
pro forma adjustments are based upon certain assumptions Rite Aid considered
reasonable under the circumstances, including certain assumptions based on the
information provided by Revco. Final amounts will differ from those set forth in
the statements.
 
   
     The pro forma information presented does not consider any future events
which may occur after the Merger has been consummated. These pro forma
statements do not present any operating expense synergies or cost reductions of
the combined operations of Rite Aid and Revco that are expected to be realized
after Rite Aid has completed its conversion of the Revco stores to the Rite Aid
format and has installed its store systems and marketing programs. See 'THE
MERGER--Estimated Synergies' for a discussion of the $156 million of cost
benefits and synergies estimated to be realized annually. The Notes to Unaudited
Pro Forma Condensed Consolidated Financial Data describe one-time Merger and
integration charges expected to be incurred primarily for store integration,
present value of estimated lease terminations and severance and retention costs.
Rite Aid estimates approximately 300 stores will be closed subsequent to the
Merger. The closings are expected to increase profitability primarily through
the pourover sales from the closed stores into existing stores while eliminating
costs of the closed stores.
    
 
     The pro forma information is presented for informational purposes only and
is not necessarily indicative of the operating results or financial position
that would have occurred had the Merger been consummated at the dates indicated,

nor is it necessarily indicative of future operating results or financial
position.
 
     The pro forma condensed financial information shoud be read in conjunction
with the consolidated financial statements of each of Rite Aid and Revco and the
related notes thereto contained in (i) Rite Aid's Annual Report on Form 10-K for
the year ended March 4, 1995, (ii) Rite Aid's Quarterly Report on Form 10-Q for
the quarter ended December 2, 1995, (iii) Revco's Annual Report to Stockholders
for the year ended June 3, 1995 and (iv) Revco's Quarterly Report on Form 10-Q
for the quarter ended November 18, 1995.

                     CONDENSED CONSOLIDATED FINANCIAL DATA
 
BASIS OF CONSOLIDATION
 
     Revco's most recent fiscal year ended June 3, 1995 and consisted of 53
weeks. For purposes of the Unaudited Pro Forma Condensed Consolidated Statement
of Operations for Rite Aid's fiscal year ended March 4, 1995, results of
operations for Revco are for the year ended June 3, 1995. Revco reports its
quarterly results for the first three quarters of the fiscal year on a
twelve-week period basis with the fourth quarter consisting of a sixteen or
seventeen week period. For purposes of the Unaudited Pro Forma Condensed
Consolidated Statement of Operations for the thirty-nine week period ended
December 2, 1995, results of operations for Revco are for the forty-one weeks
ended November 18, 1995.
 
     As a result of installing standardized store systems in all Revco
locations, and combining and standardizing various administrative support
functions such as marketing, advertising, accounting and management information
systems, Rite Aid's management expects to operate the combined operations of
Rite Aid and Revco with a more efficient overhead expense structure than each of
the two entities operating on a stand alone basis. Rite Aid also expects to
achieve cost reductions in inventory management and purchasing. However, for the
purposes of the Unaudited Pro Forma Condensed Consolidated Statements of
Operations, these and other potential synergies in overhead expenses have not
been reflected because their realization cannot be assured. See 'THE MERGER--
Estimated Synergies.'
 
DETERMINATION AND ALLOCATION OF PURCHASE PRICE
 
     Pursuant to the Merger Agreement, Rite Aid will acquire 35.1 million shares
of Revco Common Stock representing 50.1% of the outstanding shares of Revco at a
price of $27.50 per share in cash. Upon acquiring 50.1% of the outstanding
shares of Revco Common Stock, Rite Aid will acquire the remaining shares in the
Merger in exchange for Rite Aid Common Stock. The purchase price is determined
as follows and assumes a market value of each share of Rite Aid Common Stock of
$27.50, the value which represents a one-for-one conversion. If the final
determined market value of Rite Aid Common Stock is different from $27.50, the
share price will be adjusted by 50% of the increased/decreased amounts. That
difference will either increase or decrease the purchase price allocation
assigned to goodwill based on the movement of the stock price. The following
table sets forth the purchase based on the $27.50 market value used in a
one-for-one conversion:

               CONDENSED CONSOLIDATED FINANCIAL DATA--(CONTINUED)
 
 (a) Amortization of the new goodwill of $1.1461 billion plus the reorganization
     value reconstituted as new goodwill of $225.8 million over a 40 year period
     ($1.3719 billion / 40 years). The $17.6 million credit to amortization
     reflects the historical amortization of the reorganization value which is
     now included as part of the new goodwill amortization amount.
 
     The pro forma adjustment for the 39-week period ended December 2, 1995
     represents 3/4 of the annualized pro forma adjustment amount.
 
 (b) Reflects the net additional interest expense on Rite Aid's total
     borrowings. It is assumed that after completion of the Merger, Rite Aid
     will refinance or retire all of Revco's outstanding debt. Shown below are
     the components of Rite Aid's total pro forma combined debt after Revco's
     debt is refinanced or retired.
 
         7.625% on $200 million Rite Aid senior debt
         6.875% on $200 million Rite Aid senior debt
         8.25% on new $500 million Rite Aid senior debt (see Note (c) below)
         7% on $24 million of Rite Aid IDA and other debt
         $197 million of Rite Aid zero coupon bonds accreting interest at 6.75%

         6.75% on $1.808 billion of new Rite Aid bank debt
 
     For the 39 weeks ended December 2, 1995, the pro forma combined interest
     expense is equal to 3/4 of the annualized pro forma combined amount.
 
 (c) To record amortization of financing fees for the Credit Facility, based
     upon the fee arrangement of approximately $1.7 million over the five year
     term of the Credit Facility as defined in the Credit Agreement; and debt
     issue costs for $500 million in new senior debt of approximately $3.3
     million amortized over the estimated ten year life of the debt ($1.7
     million / 5 years) plus ($3.3 million / 10 years). Rite Aid anticipates
     refinancing approximately $500 million of the Credit Facility with
     long-term fixed interest rate senior debt following consummation of the
     Merger.
 
     The pro forma adjustment for the 39 weeks ended December 2, 1995 represents
     3/4 of the annualized pro forma adjustment amount.
 
 (d) Income taxes have been calculated based on Rite Aid's effective statutory
     rate for the respective periods. The amortization of the goodwill is not
     deductible for tax purposes.
 
 (e) Reflects the adjustment of LIFO inventories to FIFO carrying amounts and
     values the inventory at fair market value. Rite Aid believes FIFO carrying
     values represent estimated selling prices of merchandise inventories less
     the sum of costs of disposal and a reasonable profit allowance. This value
     is subject to revision pending completion of physical inventories.
 
 (f) Records estimated $5 million in financing fees for the Credit Facility and
     issuance of $500 million of new senior debt.
 
 (g) Records purchase price allocation to goodwill for excess of purchase price
     over net assets and direct costs of the transaction, primarily consulting
     and legal fees. Based on the purchase of 50.1% of outstanding shares of
     Revco Common Stock at $27.50 in the Offer (approximately 35,144,833 shares)
     and a one-for-one conversion of the remaining shares of Revco Common Stock
     into Rite Aid Common Stock at $27.50 per share (approximately 35,005,000
     shares).
 
 (h) Reorganization value was an intangible asset recorded by Revco upon
     emerging from Chapter 11 of the United States Bankruptcy Code and
     represents the excess of amounts charged to identifiable assets.
     Accordingly, upon completion of the Merger, the reorganization value will
     be allocated to goodwill.
 
   
 (i) Reclassify Revco's historical net deferred tax asset, record the fair value
     adjustment to inventory, and other deferred tax items.
    
 
 (j) Reclassify Rite Aid commercial paper to long-term Credit Facility, record
     issuance of debt for purchase of 50.1% of Revco Common Stock in the Offer
     and funding for financing and consulting fees. Rite Aid plans to repurchase
     or otherwise retire the Revco 9.125% Senior Notes and the Revco 10.125%

     Senior Notes with proceeds from the Credit Facility. Rite Aid has provided
     for the premium on repurchasing or otherwise retiring those Revco Notes in
     adjustment 'k.'
 
   
 (k) Records call premium on retirement of Revco outstanding debt.
    
 
   
 (l) Records issuance of 35,004,534 shares of Rite Aid Common Stock at $27.50
     per share assuming a one-for-one Exchange Ratio, and elimination of Revco
     equity accounts.
    
 
(m) Based upon the terms of the Merger Agreement, stockholders of Revco will
    receive one share of Rite Aid Common Stock for each share of Revco Common
    Stock if the average value per share of Rite Aid Common Stock during the
    Pricing Period is $27.50. If the average per share value of Rite Aid Common
    Stock is

    greater than $27.50 during the Pricing Period, Revco stockholders will
    receive 50% of the increase in market value of Rite Aid Common Stock over
    $27.50, provided that Rite Aid would not issue less than .91666 shares of
    Rite Aid Common Stock for each share of Revco Common Stock. Conversely, if
    the average per share value of Rite Aid Common Stock is less than $27.50
    during the Pricing Period, Revco stockholders will receive shares equivalent
    to the $27.50 less 50% of the decrease in market value of Rite Aid Common
    Stock from $27.50, provided that Rite Aid would not issue more than 1.125
    shares of Rite Aid Common Stock for each share of Revco Common Stock. The
    following table shows the effect on the pro forma earnings per share and
    goodwill amounts for fluctuations in the per share value of Rite Aid Common
    Stock.

 (n) Rite Aid expects to incur one-time Merger and integration charges in the
     range of $150-$175 million. Such charges are expected to consist of future
     lease costs of closed stores, severance and retention costs of employees,
     and store integration and other Merger costs. These costs will be charged
     to operations and not recorded as a liability assumed in the Merger. There
     can be no assurance, however, that the amount of such charges will not
     increase as Rite Aid's integration plan is further developed and more
     accurate estimates become possible or as to the amount of the after-tax
     cost of such charge.
    
 
   
     After consummation of the Merger, it is anticipated that stores will be
     closed in markets where a Revco store and Rite Aid store compete directly
     against one another. The specific stores to be closed, the method of
     disposition, and the closing dates have not yet been determined.
    
 
   
     Rite Aid contemplates closing redundant distribution facilities and
     eliminating duplicate corporate headquarters functions. The distribution
     centers to be closed have not been identified pending a review of the
     distribution needs of the combined company. The severance and retention
     costs of employees relate to termination or relocation of personnel at the
     stores, distribution centers and Revco's corporate headquarters to be
     closed. The employees to be terminated or relocated, and their functions
     and locations have not yet been specifically identified.
    
 
   
     Expenses associated with store integration and other Merger costs include
     training for Revco personnel to familiarize them with Rite Aid's systems
     and procedures. Also included are the costs of remerchandising the Revco
     stores to conform to Rite Aid's product mix and merchandise format. Other
     integration costs involve advertising expenses to create public awareness
     of the name change from Revco to Rite Aid.
    
 
   
     Set forth below is an analysis of the components of the estimated $150-$175
     million one-time Merger and integration costs expected to be incurred.

                     DESCRIPTION OF RITE AID CAPITAL STOCK
 
     The statements set forth under this heading with respect to the DGCL, Rite
Aid's Certificate of Incorporation (the 'Rite Aid Charter'), Rite Aid's By-laws
(the 'Rite Aid By-laws') and the Rite Aid Rights Agreement, with Harris Trust
Company of New York, as Rights Agent, are brief summaries thereof and do not
purport to be complete; such statements are subject to the detailed provisions
of the DGCL, the Rite Aid Charter, the Rite Aid By-laws and the Rite Aid Rights
Agreement. See 'Available Information.'
 
     Under Rite Aid's Charter, Rite Aid's authorized capital stock consists of
240,000,000 shares of Rite Aid Common Stock and 20,000,000 shares of Rite Aid
preferred stock, par value $1.00 per share (the 'Rite Aid Preferred Stock').
 
RITE AID PREFERRED STOCK
 
     No shares of Rite Aid Preferred Stock will be issued or outstanding
immediately following the Merger. The Rite Aid Board is authorized to issue Rite
Aid Preferred Stock in one or more series and to determine liquidation
preferences, voting rights, dividend rights, conversion rights and redemption
rights.
 
RITE AID COMMON STOCK
 
   
     Assuming the issuance of 42,865,712 shares of Rite Aid Common Stock
issuable to stockholders of Revco in the Merger and assuming the Merger occurred
as of the Record Date 126,695,042 shares of Rite Aid Common Stock would be
issued and outstanding. An additional 6,532,169 shares of Rite Aid Common Stock
are issued and held in the treasury of Rite Aid, and 6,279,486 shares of Rite
Aid Common Stock are reserved for issuance under Rite Aid's 1990 Omnibus Stock
Incentive Plan.
    
 
DIVIDEND RIGHTS
 
     The holders of Rite Aid Common Stock are entitled to receive ratably, from
funds legally available for the payment thereof, dividends when and as declared
by resolution of the Rite Aid Board, subject to any preferential dividend rights

granted to the holders of Rite Aid Preferred Stock.
 
VOTING RIGHTS
 
     Each holder of Rite Aid Common Stock is entitled to one vote in respect of
each share of such stock.
 
CHANGE OF CONTROL
 
     DGCL.  Section 203 of the DGCL prohibits generally a public Delaware
corporation, including Rite Aid, from engaging in a Business Combination (as
defined below) with an Interested Stockholder (as defined below) for a period of
three years after the date of the transaction in which an Interested Stockholder
became such, unless: (i) the board of directors of such corporation approved,
prior to the date such Interested Stockholder became such, either such Business
Combination or such transaction; (ii) upon consummation of such transaction,
such Interested Stockholder owns at least 85% of the voting shares of such
corporation (excluding specified shares); or (iii) such Business Combination is
approved by the board of directors of such corporation and authorized by the
affirmative vote (at an annual or special meeting and not by written consent) of
at least 66 2/3 % of the outstanding voting shares of such corporation
(excluding shares held by such Interested Stockholder). A 'Business Combination'
includes (i) mergers, consolidations and sales or other dispositions of 10% or
more of the assets of a corporation to or with an Interested Stockholder, (ii)
certain transactions resulting in the issuance or transfer to an Interested
Stockholder of any stock of such corporation or its subsidiaries and (iii) other
transactions resulting in a disproportionate financial benefit to an Interested
Stockholder. An 'Interested Stockholder' is a person who, together with its
affiliates and associates, owns (or within a three-year period did own) 15% or
more of a corporation's stock entitled to vote generally in the election of
directors.
 
     Charter Provisions.  The Rite Aid Charter specifies that the Rite Aid Board
shall be divided into three classes, as nearly equal in number as possible, and
shall consist of not less than three (3) nor more than fifteen (15) directors
elected for three year staggered terms. The Rite Aid By-laws provide that the
number of directors on the Rite Aid Board be fixed by the Rite Aid Board only,
or if the number is not fixed, the number will be
 
                                       79
<PAGE>
seven. The number of directors may be increased or decreased by the Rite Aid
Board only. In the interim period between annual meetings of stockholders or of
special meetings of stockholders, vacancies and newly created directorships may
be filled by the Rite Aid Board. Any directors so elected will hold office until
the next election of the class to which such directors have been elected.
 
     The Rite Aid Charter requires that any mergers, consolidations, asset
dispositions and other transactions involving a beneficial owner of 10% or more
of the voting power of the then outstanding classes of stock entitled to vote in
the election of directors (the 'Voting Stock') be approved, unless certain
conditions are satisfied, by the affirmative vote of the holders of shares
representing not less than 75% of the Voting Stock. These special voting
requirements do not apply if the transaction is approved by a majority of the

Continuing Directors (as defined below) or the consideration offered to the
stockholders of Rite Aid meets specified fair price standards (including related
procedural requirements as to the form of consideration and continued payment of
dividends). 'Continuing Directors' as defined in the Rite Aid Charter means a
member of the Rite Aid Board who was not affiliated with a Related Person (as
defined below) and was a member of the Rite Aid Board prior to the time that the
Related Person acquired the last shares of Rite Aid Common Stock entitling such
Related Person to exercise, in the aggregate, in excess of 10% of the total
voting power of all classes of Voting Stock, or any individual, corporation,
partnership, person or other entity ('Person') recommended to succeed a
Continuing Director by a majority of Continuing Directors. 'Related Person' as
defined in the Rite Aid Charter means any Person, affiliate or associate of such
Person, which has beneficial ownership directly or indirectly of shares of stock
of Rite Aid entitling such Person to exercise more than 10% of the total voting
power of all classes of Voting Stock.
 
     The Rite Aid Charter also provides that any corporate action taken at a
special meeting of stockholders called by the Rite Aid Board or by written
consent of stockholders, a majority of which are not Continuing Directors, shall
require the approval of not less than 75% of the then outstanding Voting Stock.
 
     The ability of the Rite Aid Board to issue and set the terms of Rite Aid
Preferred Stock could have the effect of making it more difficult for a third
person to acquire, or of discouraging a third person from attempting to acquire,
control of Rite Aid.
 
     Rite Aid Rights Agreement.  On April 5, 1989, the Rite Aid Board of
Directors declared a dividend distribution of one Right for each outstanding
share of Rite Aid Common Stock to stockholders of record at the close of
business on April 19, 1989. Each Right entitles the registered holder to
purchase from Rite Aid a unit consisting of one one-thousandth of a share (a
'Unit') of Series A Junior Participating Preferred Stock, par value $1.00 per
share, at a purchase price of $120 per Unit (the 'Purchase Price'), subject to
adjustment.
 
     The Rights will separate from the Rite Aid Common Stock and a distribution
date (the 'Distribution Date') will occur upon the earlier of (i) 10 business
days following a public announcement that a person or group of affiliated or
associated persons (an 'Acquiring Person') has acquired, or obtained the right
to acquire, beneficial ownership of 20% or more of the outstanding shares of
Rite Aid Common Stock (the 'Stock Acquisition Date'), (ii) 10 business days (or
such later date as may be determined by the Rite Aid Board) following the
commencement of a tender offer or exchange offer that would result in a person
or group beneficially owning 20% or more of such outstanding shares of Rite Aid
Common Stock or (iii) 10 business days after the Rite Aid Board determines any
person, alone or together with its affiliates and associates, has become the
beneficial owner of an amount of Rite Aid Common Stock which the Rite Aid Board
determines to be substantial (which amount shall in no event be less than 15% of
the shares of Rite Aid Common Stock outstanding) and at least a majority of the
Rite Aid Board who are not officers of Rite Aid, after reasonable inquiry and
investigation, shall determine that (a) such beneficial ownership by such person
is intended to cause Rite Aid to repurchase the Rite Aid Common Stock
beneficially owned by such person or to cause pressure on Rite Aid to take
action or enter into a transaction or series of transactions intended to provide

such person with short-term financial gain under circumstances where the Rite
Aid Board determines that Rite Aid's and Rite Aid's stockholders' best long-term
interests would not be served by taking such action or entering into such
transactions or series of transactions at that time or (b) such beneficial
ownership is causing or is reasonably likely to cause a material adverse impact
on the business prospects of Rite Aid (any such person is herein referred to as
an 'Adverse Person').
 
     Until the Distribution Date, (i) the Rights will be evidenced by the
certificates of Rite Aid Common Stock and will be transferred with and only with
such certificates, (ii) new Rite Aid Common Stock certificates issued after
April 19, 1989 will contain a notation incorporating the Rights Agreement by
reference and (iii) the
 
                                       80
<PAGE>
surrender or transfer of any certificates of Rite Aid Common Stock outstanding
will also constitute the transfer of the Rights associated with the Rite Aid
Common Stock represented by such certificate.
 
     The Rights are not exercisable until the Distribution Date and will expire
at the close of business on April 5, 1999, unless earlier redeemed by Rite Aid.
 
     In the event that (i) a person becomes the beneficial owner of 20% or more
of the then outstanding shares of Rite Aid Common Stock (except pursuant to an
offer for all outstanding shares which at least a majority of non-interested
directors of Rite Aid determine to be fair to and otherwise in the best
interests of Rite Aid and its stockholders) or (ii) the Rite Aid Board
determines that a person is an Adverse Person, each Right holder will thereafter
have the right to receive, upon exercise, Rite Aid Common Stock (or, in certain
circumstances, cash, property or other securities of Rite Aid) having a value
equal to two times the exercise price of the Right. Notwithstanding any of the
foregoing, following the occurrence of any of the events set forth in this
paragraph, all Rights that are, or (under certain circumstances) were,
beneficially owned by any Acquiring Person or Adverse Person will be null and
void. However, Rights are not exercisable following the occurrence of either of
the events set forth above until such time as the Rights are no longer
redeemable by Rite Aid.
 
     In the event that, at any time following the Stock Acquisition Date (i)
Rite Aid is acquired in a merger or other business combination transaction in
which Rite Aid is not the surviving corporation (other than mergers which follow
certain types of offers) or (ii) more than 50% of Rite Aid's assets, cash flow
or earning power is sold or transferred, each holder of a Right (except voided
Rights) shall thereafter have the right to receive, upon exercise, common stock
of the acquiring company having a value equal to two times the exercise price of
the Right. In the event that Rights cannot be exercised for common stock of the
acquiring company as set forth above, holders of Rights will be entitled to put
the Rights to the Acquiring Person for cash equal to the Purchase Price.
 
     The Purchase Price payable, and the number of Units of Rite Aid Preferred
Stock or other securities or property issuable, upon exercise of the Rights are
subject to adjustment from time to time to prevent dilution (i) in the event of
a stock dividend on, or a subdivision, combination or reclassification of, Rite

Aid Preferred Stock, (ii) if holders of Rite Aid Preferred Stock are granted
certain rights or warrants to subscribe for Rite Aid Preferred Stock or
convertible securities at less than the current market price of the Rite Aid
Preferred Stock, or (iii) upon the distribution to holders of the Rite Aid
Preferred Stock of evidences of indebtedness or assets (excluding regular
quarterly cash dividends) or of subscription rights or warrants (other than
those referred to above).
 
     In general, at any time until 10 business days following the Stock
Acquisition Date, Rite Aid may redeem the Rights in whole, but not in part, at a
price of $.01 per Right (payable in cash, Rite Aid Common Stock or other
consideration deemed appropriate by the Rite Aid Board). Rite Aid may not redeem
the Rights if the Rite Aid Board had previously declared a person to be an
Adverse Person. Immediately upon the action of the Rite Aid Board ordering
redemption of the Rights, the Rights will terminate and the only right of the
holders of Rights will be to receive the $.01 redemption price.
 
     Each share of Revco Common Stock issued to holders of Revco Common Stock in
the Merger will be issued together with one associated Right in accordance with
the Rite Aid Rights Agreement.
 
MISCELLANEOUS
 
     The holders of Rite Aid Common Stock do not have preemptive, subscription,
redemption or conversion rights. The outstanding shares of Rite Aid Common Stock
are, and the shares of Rite Aid Common Stock constituting the Share Issuance
upon issuance will be, duly authorized, validly issued, fully paid,
nonassessable and the outstanding shares of Rite Aid Common Stock are, and the
shares of Rite Aid Common Stock constituting the Share Issuance upon notice of
issuance will be, listed on the NYSE and the PSE.

     The consolidated financial statements of Rite Aid Corporation as of March
4, 1995 and February 26, 1994, and for each of the years in the three-year
period ended March 4, 1995, have been incorporated by reference in this Proxy
Statement in reliance upon the report of KPMG Peat Marwick LLP, independent
certified public accountants, incorporated by reference herein, and upon the
authority of said firm as experts in accounting and auditing. The report of KPMG
Peat Marwick LLP covering the March 4, 1995 consolidated financial statements
contains an explanatory paragraph describing changes in accounting principles.
 
     With respect to the unaudited interim financial information of Rite Aid
Corporation for the periods ended June 3, 1995, September 2, 1995, and December
2, 1995 incorporated by reference herein, KPMG Peat Marwick LLP has reported
that they applied limited procedures in accordance with professional standards
for a review of such information. However, their separate report included in
Rite Aid's quarterly reports on Form 10-Q for the quarters ended June 3, 1995,
September 2, 1995, and December 2, 1995 and incorporated by reference herein,
state that they did not audit and they do not express an opinion on the interim
financial information. Accordingly, the degree of reliance on their reports on
such information should be restricted in light of the limited nature of the
review procedures applied. The accountants are not subject to the liability
provisions of Section 11 of the Securities Act for their report on the unaudited
interim financial information because that report is not a 'report' or a 'part'
of the Proxy Statement prepared or certified by the accountants within the
meaning of Sections 7 and 11 of the Securities Act.
 
     The consolidated financial statements of Revco incorporated by reference in
this Proxy Statement to the extent and for the periods indicated in their report
have been audited by Arthur Andersen LLP, independent public accountants, and
are incorporated herein in reliance upon the authority of said firm as experts
in accounting and auditing in giving said report.
 
                            STOCKHOLDERS' PROPOSALS
 
     It is presently anticipated that Rite Aid will hold its 1996 Annual Meeting
on or about June 26, 1996. Any stockholder wishing to submit a proposal to Rite
Aid for consideration for inclusion in its proxy statement relating to its 1996
Annual Meeting of Stockholders must have delivered such proposal to Rite Aid by
February 8, 1996.

                          AGREEMENT AND PLAN OF MERGER
 
     AGREEMENT AND PLAN OF MERGER, dated as of November 29, 1995, by and among
Rite Aid Corporation, a Delaware corporation ('Parent'), Ocean Acquisition
Corporation, a Delaware corporation and a wholly owned subsidiary of Parent
('Sub'), and Revco D.S., Inc., a Delaware corporation (the 'Company').
 
     WHEREAS, the Boards of Directors of Parent, Sub and the Company have
approved, and deem it advisable and in the best interests of their respective
stockholders to consummate, the acquisition of the Company by Parent upon the
terms and subject to the conditions set forth herein;
 
     WHEREAS, it is intended that the acquisition be accomplished by Sub
commencing a cash tender offer for Shares (as defined in Section 1.1) to be
followed by a merger of Sub with and into the Company (the 'Merger'), with the
Company being the surviving corporation;
 
     WHEREAS, as a condition and inducement to Parent and Sub entering into this
Agreement and incurring the obligations set forth herein, concurrently with the
execution and delivery of this Agreement, Parent is entering into a Stockholder
Agreement with Zell/Chilmark Fund, L.P. in the form of Exhibit A hereto (the
'Zell/Chilmark Stockholder Agreement'), pursuant to which, among other things,
such stockholder has agreed to vote the Shares then owned by such stockholder in
favor of the Merger provided for herein;
 
     WHEREAS, as a condition and inducement to Parent and Sub entering into this
Agreement and incurring the obligations set forth herein, concurrently with the
execution and delivery of this Agreement, Parent and the Company are entering
into a Stock Option Agreement in the form of Exhibit B hereto (the 'Stock Option
Agreement'), pursuant to which, among other things, the Company has granted
Parent the right to purchase Shares representing 19.9% of the outstanding Shares
at the date of exercise under certain circumstances;
 
     WHEREAS, the Board of Directors of the Company has approved the
transactions contemplated by this Agreement, the Zell/Chilmark Stockholder
Agreement and the Stock Option Agreement in accordance with the provisions of
Section 203 of the Delaware General Corporation Law (the 'DGCL') and has
resolved to recommend the acceptance of the Offer (as defined in Section 1.1)
and the approval of the Merger by the holders of Shares; and
 
     NOW, THEREFORE, in consideration of the foregoing and the respective
representations, warranties, covenants and agreements set forth herein and in
the Zell/Chilmark Stockholder Agreement and the Stock Option Agreement, the
parties hereto agree as follows:
 
                                   ARTICLE I

                              THE OFFER AND MERGER
 
     Section 1.1 The Offer.  (a) As promptly as practicable (but in no event
later than five business days after the public announcement of the execution
hereof), Sub shall commence (within the meaning of Rule 14d-2 under the
Securities Exchange Act of 1934, as amended (the 'Exchange Act')) an offer (the
'Offer') to purchase for cash not less than 35,144,833 shares and up to all of
the issued and outstanding common stock, par value $.01 per share (referred to
herein as either the 'Shares' or 'Company Common Stock'), of the Company at a
price of $27.50 per Share, net to the seller in cash (such price, or such higher
price per Share as may be paid in the Offer, being referred to herein as the
'Offer Price'), the exact number of Shares within such range to be determined by
Parent in its sole discretion, it being hereby agreed that Parent may change the
amount of Shares sought to be purchased in the Offer within such range at any
time prior to consummation of the Offer, provided that Parent complies with the
requirements of Rule 14e-1 of the Exchange Act. The Offer shall be subject to
there being validly tendered and not withdrawn prior to the expiration of the
Offer, at least 35,144,833 Shares or such other number of Shares as shall equal
50.1% of the Shares outstanding on a fully-diluted basis as of the expiration of
the Offer (the 'Minimum Condition') and to the other conditions set forth in
Annex A hereto. Sub shall, on the terms and subject to the prior satisfaction or
waiver of the conditions of the Offer, accept for payment and pay for Shares
tendered as soon as practicable after the later of the satisfaction of the
conditions to the Offer and the expiration of the Offer; provided, however, that
no such payment shall be made until after any calculation of proration as
required by applicable law. The obligations of Sub to commence the Offer and to
accept for payment and to pay for any Shares validly tendered on or prior to the
expiration of the Offer and not withdrawn shall be
 
                                      A-1
<PAGE>
subject only to the conditions set forth in Annex A hereto. The Offer shall be
made by means of an offer to purchase (the 'Offer to Purchase') containing the
terms set forth in this Agreement and the conditions set forth in Annex A
hereto. Without the written consent of the Company, Sub shall not amend or waive
the Minimum Condition, decrease the Offer Price, change the number of Shares
sought to an amount less than 50.1% of the outstanding Shares on a fully-diluted
basis, change the form of consideration to be paid pursuant to the Offer or
impose conditions to the Offer in addition to those set forth in Annex A hereto,
or amend any other term or condition of the Offer in any manner which is adverse
to the holders of Shares; provided, however, that if on the initial scheduled
expiration date of the Offer (as it may be extended in accordance with the terms
hereof), all conditions to the Offer shall not have been satisfied or waived,
the Offer may be extended from time to time without the consent of the Company
for such period of time as is reasonably expected to be necessary to satisfy the
unsatisfied conditions. In addition, the Offer Price may be increased and the
Offer may be extended to the extent required by law in connection with such
increase in each case without the consent of the Company.
 
     (b) Parent and Sub shall file with the United States Securities and
Exchange Commission (the 'SEC') as soon as practicable on the date the Offer is
commenced, a Tender Offer Statement on Schedule 14D-1 with respect to the Offer
(together with all amendments and supplements thereto and including the exhibits
thereto, the 'Schedule 14D-1') which will include, as exhibits, the Offer to

Purchase and a form of letter of transmittal and summary advertisement
(collectively, together with the Schedule 14D-1 and any amendments and
supplements thereto, the 'Offer Documents'). Parent and Sub represent that the
Offer Documents will comply in all material respects with the provisions of
applicable federal securities laws and, on the date filed with the SEC and on
the date first published, sent or given to the Company's stockholders, will not
contain any untrue statement of a material fact or omit to state any material
fact required to be stated therein or necessary in order to make the statements
therein, in light of the circumstances under which they were made, not
misleading, except that no representation is made by Parent or Sub with respect
to information supplied by the Company in writing for inclusion in the Offer
Documents. The information supplied by the Company for inclusion in the Offer
Documents will not, on the date filed with the SEC and on the date first
published, sent or given to the Company's stockholders, contain any untrue
statement of a material fact or omit to state any material fact required to be
stated therein or necessary in order to make the statements therein, in light of
the circumstances under which they were made, not misleading. Each of Parent and
Sub further agrees to take all steps necessary to cause the Offer Documents to
be filed with the SEC and to be disseminated to holders of Shares, in each case
as and to the extent required by applicable federal securities laws. Each of
Parent and Sub, on the one hand, and the Company, on the other hand, agrees
promptly to correct any information provided by it for use in the Offer
Documents if and to the extent that it shall have become false and misleading in
any material respect, and Parent and Sub further agree to take all steps
necessary to cause the Offer Documents as so corrected to be filed with the SEC
and to be disseminated to holders of Shares, in each case as and to the extent
required by applicable federal securities laws. The Company and its counsel
shall be given the opportunity to review the Schedule 14D-1 and the Offer
Documents before they are filed with the SEC. In addition, Parent and Sub agree
to provide the Company and its counsel in writing with any comments Parent, Sub
or their counsel may receive from time to time from the SEC or its staff with
respect to the Offer Documents promptly after the receipt of such comments.
Parent and Sub will cooperate with the Company in responding to any comments
received from the SEC with respect to the Offer and amending the Offer in
response to any such comments.
 
     Section 1.2 Company Actions.  (a) The Company hereby approves of and
consents to the Offer and represents that the Board of Directors, at a meeting
duly called and held, has unanimously (with one director absent and two
directors abstaining) (i) determined that this Agreement and the transactions
contemplated hereby, including, without limitation, the Offer, the Merger, the
Zell/Chilmark Stockholder Agreement, the Stock Option Agreement and the
transactions contemplated thereby, are fair to and in the best interests of the
holders of Shares, (ii) approved this Agreement and the transactions
contemplated hereby, including, without limitation, the Offer and the Merger,
and approved the Zell/Chilmark Stockholder Agreement, the Stock Option Agreement
and the transactions contemplated thereby, such determination and approval
constituting approval thereof for purposes of Section 203 of the DGCL, and (iii)
resolved to recommend that the stockholders of the Company who desire to receive
cash for their Shares accept the Offer and tender their Shares thereunder to Sub
and that all stockholders of the Company approve and adopt this Agreement;
provided, however, that prior to the purchase by Sub of Shares pursuant to the
Offer, the Company may modify, withdraw or change such recommendation only to
the extent that the Board of Directors of the Company determines, after having

received the oral or written opinion of
 
                                      A-2
<PAGE>
outside legal counsel to the Company, that the failure to so withdraw, modify or
change would result in a breach of the Board of Directors' fiduciary duties
under applicable laws.
 
     (b) Concurrently with the commencement of the Offer, the Company shall file
with the SEC a Solicitation/Recommendation Statement on Schedule 14D-9 (together
with all amendments and supplements thereto and including the exhibits thereto,
the 'Schedule 14D-9') which shall contain the recommendation referred to in
clauses (i), (ii) and (iii) of Section 1.2(a) hereof; provided, however, that
the Company may modify, withdraw or change such recommendation only to the
extent that the Board of Directors of the Company determines, after having
received the oral or written opinion of outside legal counsel to the Company,
that the failure to so withdraw, modify or change would result in a breach of
the Board of Directors' fiduciary duties under applicable laws and any such
withdrawal, change or modification shall not constitute a breach of this
Agreement. The Company represents that the Schedule 14D-9 will comply in all
material respects with the provisions of applicable federal securities laws and,
on the date filed with the SEC and on the date first published, sent or given to
the Company's stockholders, shall not contain any untrue statement of a material
fact or omit to state any material fact required to be stated therein or
necessary in order to make the statements therein, in light of the circumstances
under which they were made, not misleading, except that no representation is
made by the Company with respect to information supplied by Parent or Sub for
inclusion in the Schedule 14D-9. The information supplied by Parent and Sub for
inclusion in the Schedule 14D-9 will not, on the date filed with the SEC and on
the date first published, sent or given to the Company's stockholders, contain
any untrue statement of a material fact or omit to state any material fact
required to be stated therein or necessary in order to make the statements
therein, in light of the circumstances under which they were made, not
misleading. The Company further agrees to take all steps necessary to cause the
Schedule 14D-9 to be filed with the SEC and to be disseminated to holders of
Shares, in each case as and to the extent required by applicable federal
securities laws. Each of the Company, on the one hand, and Parent and Sub, on
the other hand, agrees promptly to correct any information provided by it for
use in the Schedule 14D-9 if and to the extent that it shall have become false
and misleading in any material respect and the Company further agrees to take
all steps necessary to cause the Schedule 14D-9 as so corrected to be filed with
the SEC and to be disseminated to holders of Shares, in each case as and to the
extent required by applicable federal securities laws. Parent and its counsel
shall be given the opportunity to review the Schedule 14D-9 before it is filed
with the SEC. In addition, the Company agrees to provide Parent, Sub and their
counsel in writing with any comments the Company 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. The Company will cooperate with
Parent and Sub in responding to any comments received from the SEC with respect
to the Schedule 14D-9 and amending the Schedule 14D-9 in response to any such
comments.
 
     (c) In connection with the Offer, if requested by Sub, the Company will
promptly furnish or cause to be furnished to Sub mailing labels, security

position listings and any available listing or computer file containing the
names and addresses of the record holders of the Shares as of a recent date, and
shall furnish Sub with such information and assistance as Sub or its agents may
reasonably request in communicating the Offer to the stockholders of the
Company. Except for such steps as are necessary to disseminate the Offer
Documents, Parent and Sub shall hold in confidence the information contained in
any of such labels and lists and the additional information referred to in the
preceding sentence, will use such information only in connection with the Offer,
and, if this Agreement is terminated, will upon request of the Company deliver
or cause to be delivered to the Company all copies of such information then in
its possession or the possession of its agents or representatives.
 
     (d) The Board of Directors of the Company has received the written opinion
of Morgan Stanley & Co. Incorporated ('Company Financial Advisor'), dated as of
a date which is on or prior to the date of this Agreement, to the effect that,
as of such date, the consideration to be received by holders of Shares (other
than Sub and its affiliates) pursuant to the Offer and Merger, taken together,
is fair from a financial point of view to such holders (the 'Company Fairness
Opinion'). The Company has delivered to Sub a copy of the Company Fairness
Opinion, together with Company Financial Advisor's authorization to the
inclusion of the Company Fairness Opinion in the Offer Documents and the Proxy
Statement/Prospectus (as defined in Section 1.7).
 
     Section 1.3 The Merger.  Subject to the terms and conditions of this
Agreement and in accordance with the DGCL at the Effective Time, the Company and
Sub shall consummate a merger (the 'Merger') pursuant to which (i) Sub shall be
merged with and into the Company and the separate corporate existence of Sub
shall thereupon cease, and (ii) the Company shall be the successor or surviving
corporation in the Merger (the
 
                                      A-3
<PAGE>
'Surviving Corporation') and shall continue to be governed by the laws of the
State of Delaware. Pursuant to the Merger, (x) the Certificate of Incorporation
of the Company, as in effect immediately prior to the Effective Time, shall be
the Certificate of Incorporation of the Surviving Corporation until thereafter
amended as provided by law and such Certificate of Incorporation, and (y) the
By-laws of the Company, as in effect immediately prior to the Effective Time,
shall be the By-laws of the Surviving Corporation until thereafter amended as
provided by law, the Certificate of Incorporation of the Surviving Corporation
and such By-laws. The Merger shall have the effects set forth in the DGCL.
 
     Section 1.4 Effective Time.  (a) Parent, Sub and the Company will cause a
Certificate of Merger (the 'Certificate of Merger') with respect to the Merger
to be executed and filed on the date of the Closing (as defined in Section 1.5)
(or on such other date as Parent and the Company may agree) with the Secretary
of State of the State of Delaware as provided in the DGCL. The Merger shall
become effective on the date on which the Certificate of Merger has been duly
filed with the Secretary of State or such time as is agreed upon by the parties
and specified in the Certificate of Merger, and such time is hereinafter
referred to as the 'Effective Time'.
 
     (b) If Shares are purchased in the Offer, Parent and Sub covenant and agree
to consummate the Merger pursuant to the terms of this Agreement not later than

June 30, 1996.
 
     Section 1.5 Closing.  The closing of the Merger (the 'Closing') will take
place at 10:00 a.m., New York City time, on a date to be specified by the
parties, which shall be no later than the third business day after satisfaction
or waiver of all of the conditions set forth in Article VII hereof (the 'Closing
Date'), at the offices of Skadden, Arps, Slate, Meagher & Flom, 919 Third
Avenue, New York, New York, unless another time, date or place is agreed to in
writing by the parties hereto.
 
     Section 1.6 Directors and Officers.  (a) Promptly upon the acceptance for
payment of any Shares by Parent or any of its Subsidiaries (as defined in
Section 3.1 hereof) pursuant to the Offer, Parent shall be entitled to designate
such number of directors, rounded up to the next whole number, on the Board of
Directors of the Company as is equal to the product of the total number of
directors on such Board (giving effect to the directors designated by Parent
pursuant to this sentence) multiplied by the percentage that the aggregate
number of Shares beneficially owned by Sub, Parent and any of their affiliates
bears to the total number of shares of Company Common Stock then outstanding.
The Company shall, upon request of Parent, use its best efforts promptly either
to increase the size of its Board of Directors or, at the Company's election,
secure the resignations of such number of its incumbent directors as is
necessary to enable Parent's designees to be so elected to the Company's Board,
and shall cause Parent's designees to be so elected. At such time, the Company
shall also cause persons designated by Parent to constitute the same percentage
(rounded up to the next whole number) as is on the Company's Board of Directors
of (i) each committee of the Company's Board of Directors, (ii) each board of
directors (or similar body) of each Subsidiary of the Company and (iii) each
committee (or similar body) of each such board, in each case only to the extent
permitted by applicable law or the rules of any stock exchange on which the
Company Common Stock is listed. Notwithstanding the foregoing, until the
Effective Time, each of Parent, Sub and the Company shall use its best efforts
to retain as a member of the Company's Board of Directors at least two directors
who are directors of the Company on the date hereof (the 'Continuing
Directors'); provided, that subsequent to the purchase of and payment for Shares
pursuant to the Offer, Parent shall always have its designees represent at least
a majority of the entire Board of Directors. In the event of a vacancy on the
Board of Directors resulting from the resignation or death of any Continuing
Director, such vacancy shall be filled by the remaining Continuing Directors, or
if there are no remaining Continuing Directors by the designees of Zell/Chilmark
Fund, L.P. The Company's obligations under this Section 1.6(a) shall be subject
to Section 14(f) of the Exchange Act and Rule 14f-1 promulgated thereunder. The
Company shall promptly take all actions required pursuant to such Section 14(f)
and Rule 14f-1 in order to fulfill its obligations under this Section 1.6(a),
including mailing to stockholders the information required by such Section 14(f)
and Rule 14f-1 as is necessary to enable Parent's designees to be elected to the
Company's Board of Directors. Parent or Sub will supply the Company any
information with respect to either of them and their nominees, officers,
directors and affiliates required by such Section 14(f) and Rule 14f-1. The
provisions of this Section 1.6(a) are in addition to and shall not limit any
rights which Sub, Parent or any of their affiliates may have as a holder or
beneficial owner of Shares as a matter of law with respect to the election of
directors or otherwise.

     (b) From and after the time, if any, that Parent's designees constitute a
majority of the Company's Board of Directors and prior to the Effective Time,
(i) any material amendment of this Agreement, (ii) any termination of this
Agreement by the Company, (iii) any extension of time for performance of any of
the obligations of Parent or Sub hereunder, (iv) any waiver of any condition or
any of the Company's rights hereunder, (v) any amendment or change to the
Certificate of Incorporation or By-laws of the Company or any of its
Subsidiaries, (vi) any amendment or change to any Benefit Plan (as defined in
Section 3.9(a)) or compensation policies or severance obligations (including
those agreements or obligations referenced in Section 3.9 hereof or set forth in
Schedule 3.9 of the Company Disclosure Schedule) or (vii) any amendment or
change to the policies of directors' and officers' liability insurance
maintained by the Company and its Subsidiaries on the date hereof, may be
effected only by the action of a majority of the Board of Directors of the
Company, which majority includes a majority of the Continuing Directors;
provided, that if there shall be no Continuing Directors, actions may be
effected by majority vote of the entire Board of Directors of the Company. Any
actions with respect to the enforcement of this Agreement by the Company shall
be effected only by the action of a majority of the Continuing Directors.
 
     (c) The directors and officers of Sub at the Effective Time shall, from and
after the Effective Time, be the initial directors and officers of the Surviving
Corporation until their successors shall have been duly elected or appointed or
qualified or until their earlier death, resignation or removal in accordance
with the Surviving Corporation's Certificate of Incorporation and By-laws.
 
     Section 1.7 Stockholders' Meetings.  (a) In order to consummate the Merger,
the Company, acting through its Board of Directors, shall, in accordance with
applicable law, duly call, give notice of, convene and hold a special meeting of
its stockholders (the 'Company Special Meeting'), as soon as practicable after
the registration statement on Form S-4 (together with all amendments, schedules,
and exhibits thereto) to be filed by Parent in connection with the registration
of the Parent Common Stock to be issued by Parent in the Merger (the
'Registration Statement') is declared effective, for the purpose of considering
and taking action upon this Agreement. The Company shall include in the joint
proxy statement/prospectus forming a part of the Registration Statement (the
'Proxy Statement/Prospectus') the recommendation of the Board of Directors of
the Company that stockholders of the Company vote in favor of the approval of
the Merger and the adoption of this Agreement. Parent agrees that it will vote,
or cause to be voted, all of the Shares then owned by it, Sub or any of its
other Subsidiaries, in favor of the approval of the Merger and adoption of the
Merger Agreement at the Company Special Meeting.
 
     (b) In order to consummate the Merger, Parent, acting through its Board of
Directors, shall, in accordance with applicable law, duly call, give notice of,
convene and hold a special meeting of its stockholders (the 'Parent Special
Meeting' and together with the Company Special Meeting, the 'Special Meetings'),
as soon as practicable after the Registration Statement is declared effective,
for the purpose of authorizing the issuance of shares of Parent Common Stock (as
defined below) pursuant to the Merger. Parent shall include in the Proxy
Statement/Prospectus the recommendation of the Board of Directors of Parent that
stockholders of Parent vote in favor of the issuance of shares of Parent common

stock, par value $1.00 per share ('Parent Common Stock'), in the Merger.
 
     (c) Nothing in this Section 1.7 is intended to impair the fiduciary duties
of the Boards of Directors of the Company or Parent or, in the case of the Board
of Directors of the Company, to restrict its ability to exercise its right of
termination pursuant to Section 7.1(c)(1) of this Agreement.

                              CONVERSION OF SHARES
 
     Section 2.1 Conversion of Shares.  (a) Each share of Common Stock, par
value $.01 per share, of Sub issued and outstanding immediately prior to the
Effective Time, without any other action by Parent, Sub or the Company, shall,
at the Effective Time, be converted into and become one fully paid and
nonassessable share of common stock of the Surviving Corporation.
 
     (b) Each share of Company Common Stock issued and outstanding immediately
prior to the Effective Time (other than Shares to be cancelled pursuant to
Section 2.1(d) hereof and other than Dissenting Shares (as defined in Section
2.6), if any) shall, at the Effective Time, by virtue of the Merger and without
any action on the part of the holder thereof, be converted into either (i) the
right to receive a number of duly authorized, validly issued, fully paid and
nonassessable shares of Parent Common Stock determined as set forth in clause
(c) below; provided that Parent shall not issue more than 1.12500 nor less than
 .91666 shares of Parent Common Stock per Share (the 'Exchange Ratio') or (ii) if
the alternative consideration contemplated by Section 2.2 hereof is applicable,
then the right to receive the Alternative Consideration (as defined in Section
2.2), plus, in each of clause (i) and (ii) above, any Additional Consideration
contemplated by Section 2.2 hereof.
 
     (c) For purposes hereof, 'Average Parent Share Price' shall mean the
average closing price per share of Parent Common Stock on the New York Stock
Exchange (the 'NYSE') as reported on the NYSE Composite Tape for fifteen NYSE
trading days selected by Parent and the Company by lot from among the forty NYSE
trading days ending on the fifth trading day immediately preceding the Company
Special Meeting. 'Transaction Price' shall mean $27.50 per Share. The number of
shares of Parent Common Stock into which each Share shall be converted in the
Merger shall be determined as follows:
 
          1. In the event the Average Parent Share Price equals the Transaction
     Price, each Share shall be converted into one share of Parent Common Stock.
 
          2. In the event that the Average Parent Share Price is greater than
     the Transaction Price, each Share shall be converted into a number of
     shares of Parent Common Stock (rounded to the nearest one one-hundred
     thousandth) determined by the following formula:
 
<TABLE>
<S>                                           <C>      <C>
          Number of shares of Parent Common            Transaction Price plus .5 x (Average
          Stock                                  =     Parent Share Price minus Transaction Price)
                                                       -------------------------------------------
                                                       Average Parent Share Price

</TABLE>
 
          3. In the event that the Average Parent Share Price is less than the
     Transaction Price, each Share shall be converted, at the option of Parent,
     into either:
 
            (I) a number of shares of Parent Common Stock (rounded to the
            nearest one one-hundred thousandth) determined by the following
            formula:
 
<TABLE>
<S>                                           <C>     <C>
          Number of shares of Parent Common           Transaction Price minus .5 x (Transaction
          Stock                                  =    Price minus Average Parent Share Price)
                                                      -----------------------------------------
                                                             Average Parent Share Price
</TABLE>
 
            or (II) one share of Parent Common Stock plus the Cash Adjustment
            Amount, without any interest thereon, where the Cash Adjustment
            Amount is determined by the following formula:
 
<TABLE>
<S>                                           <C>   <C>
          Cash Adjustment Amount                 =  .5 x (Transaction Price minus Average Parent Share Price);
</TABLE>
 
            provided, however, in no event shall the Cash Adjustment Amount be
            greater than $2.75 per Share.
 
     (d) All shares of Company Common Stock that are owned by the Company as
treasury stock and any shares of Company Common Stock owned by Parent, Sub or
any other direct or indirect wholly owned Subsidiary of Parent shall, at the
Effective Time, be cancelled and retired and shall cease to exist and no Parent
Common Stock or cash, if the alternative consideration contemplated by Section
2.2 hereof is applicable, shall be delivered in exchange therefor.
 
     (e) On and after the Effective Time, holders of certificates which
immediately prior to the Effective Time represented outstanding Shares (the
'Certificates') shall cease to have any rights as stockholders of the Company,
except the right to receive the consideration set forth in this Article II
(other than the Additional
 
                                      A-6
<PAGE>
Consideration provided by Section 2.2(c) hereof) (the 'Merger Consideration')
for each Share held by them or, if applicable, payments due to holders of
Dissenting Shares (as defined in Section 2.6 hereof).
 
     Section 2.2 Alternative Consideration and Additional Consideration.  (a) In
the event that the stockholders of Parent shall not approve the issuance of
Parent Common Stock pursuant to the Merger at the Parent Special Meeting, but
all conditions to the Merger are otherwise satisfied or waived (if permissible),
the Company, Parent and Sub shall nonetheless consummate the Merger and each
share of Company Common Stock issued and outstanding immediately prior to the

Effective Time (other than treasury Shares and Shares owned by Parent and its
Subsidiaries) shall, at the Effective Time, by virtue of the Merger and without
any action on the part of the holder hereof, be converted into the right to
receive the following consideration (the 'Alternative Consideration') in a
combination of shares of Parent Common Stock and cash determined as follows:
 
          1. The number of shares of Parent Common Stock into which each Share
     shall be converted in the Merger (the 'Adjusted Exchange Ratio') shall
     equal the Exchange Ratio determined pursuant to Section 2.1(c) hereof
     (assuming no Cash Adjustment Amount is paid) multiplied by a fraction (the
     'Adjustment Fraction'), the numerator of which is the number of shares of
     Parent Common Stock equal to 19.9% of the then outstanding shares of Parent
     Common Stock and the denominator of which is (a) the Exchange Ratio
     multiplied by (b) the aggregate number of outstanding Shares (other than
     treasury Shares and Shares owned by Parent and its Subsidiaries); and
 
          2. The amount of cash (the 'Adjusted Alternative Cash Consideration')
     into which each Share shall be converted in the Merger shall equal the
     Transaction Price multiplied by 1 minus the Adjustment Fraction.
 
     (b) In the event the Merger is not consummated prior to April 29, 1996 and
the Company shall not have materially breached this Agreement (other than by
acts caused or permitted by Parent), then the stockholders of the Company shall
be entitled to receive interest on the amount of the Merger Consideration that
they receive, from April 29, 1996 until the earlier of the Effective Time or
June 30, 1996, calculated at an annual rate equal to the prime rate of interest
(as announced from time to time by Morgan Guaranty Trust Company of New York).
For purposes of calculating the Merger Consideration, the Average Parent Share
Price, if not otherwise ascertainable in accordance with the terms of this
Agreement, shall be the average price of Parent Common Stock based on the 15
highest closing prices of Parent Common Stock since the consummation of the
Offer until the earlier of June 30, 1996 or the Effective Time.
 
     (c) In the event Parent and/or Sub, in violation of their obligations under
this Agreement, fails or refuses to consummate the Merger on or prior to June
30, 1996 and the Company shall not have materially breached this Agreement
(other than by acts caused or permitted by Parent), then, in addition to any
rights or remedies that the Company and its stockholders otherwise have in law
or at equity as a result thereof, the stockholders of the Company shall be
entitled to receive interest from June 30, 1996 on the amount of the Merger
Consideration not paid until such Merger Consideration is paid, calculated at
the annual rate of the higher of (i) the prime rate of interest (as announced
from time to time by Morgan Guaranty Trust Company of New York) plus 300 basis
points or (ii) the amount otherwise permitted by law. For purposes of
calculating the Merger Consideration, the Average Parent Share Price, if not
otherwise ascertainable in accordance with the terms of this Agreement, shall be
the average price of Parent Common Stock based on the 15 highest closing prices
of Parent Common Stock since the consummation of the Offer until such Merger
Consideration is paid. Any additional consideration paid or payable pursuant to
Section 2.2(b) or Section 2.2(c) is referred to herein as 'Additional
Consideration'.
 
     Section 2.3 Issuance of Parent Common Stock or Payment of Cash
Consideration.  (a) The manner in which each Share (other than Shares to be

cancelled as set forth in Section 2.1(d)) shall be converted into Parent Common
Stock or, if the Alternative Consideration contemplated by Section 2.2 hereof is
applicable, the right to receive the Alternative Consideration in the Merger
shall be as set forth in this Section 2.3.
 
     (b) No certificates or scrip representing fractional shares of Parent
Common Stock shall be issued upon the surrender for exchange of Certificates
representing Shares, no dividend or distribution with respect to shares shall be
payable on or with respect to any fractional share and such fractional share
interests shall not entitle the owner thereof to vote or to any other rights of
a stockholder of Parent. In lieu of any such fractional share of Parent Common
Stock, Parent shall pay to each former stockholder of the Company who otherwise
would be entitled to receive a fractional share of Parent Common Stock an amount
in cash determined by multiplying (i) the Average Parent Share Price on the date
on which the Effective Time occurs by (ii) the fractional interest in a share of
Parent Common Stock to which such holder would otherwise be entitled.
 
                                      A-7
<PAGE>
     (c) Parent shall designate a bank or trust company to act as agent for the
holders of shares of Company Common Stock in connection with the Merger (the
'Exchange Agent') to receive the shares of Parent Common Stock and the Cash
Adjustment Amount, if any, or the Alternative Consideration, as the case may be,
and any Additional Consideration to which holders of shares of Company Common
Stock shall become entitled pursuant to this Article II.
 
     (d) As soon as reasonably practicable after the Effective Time, the
Exchange Agent shall mail to each holder of record of a Certificate whose shares
were converted pursuant to this Article II into the right to receive the Merger
Consideration (i) a letter of transmittal (which shall specify that delivery
shall be effected, and risk of loss and title to the Certificates shall pass,
only upon delivery of the Certificates to the Exchange Agent and shall be in
such form and have such other provisions as Parent may reasonably specify) and
(ii) instructions for use in effecting the surrender of the Certificates in
exchange for the Merger Consideration and any Additional Consideration
contemplated by Section 2.2(c). Upon surrender of a Certificate for cancellation
to the Exchange Agent or to such other agent or agents as may be appointed by
Parent, together with such letter of transmittal, duly executed, the holder of
such Certificate shall be entitled to receive in exchange therefor the Merger
Consideration and any Additional Consideration contemplated by Section 2.2(c)
for each share of Company Common Stock formerly represented by such Certificate
and the Certificate so surrendered shall forthwith be cancelled. If payment of
the Merger Consideration and any Additional Consideration contemplated by
Section 2.2(c) is to be made to a person other than the person in whose name the
surrendered Certificate is registered, it shall be a condition of payment that
the Certificate so surrendered shall be properly endorsed or shall be otherwise
in proper form for transfer and that the person requesting such payment shall
have paid any transfer and other taxes required by reason of the payment of the
Merger Consideration and any Additional Consideration contemplated by Section
2.2(c) to a person other than the registered holder of the Certificate
surrendered or shall have established to the satisfaction of the Surviving
Corporation that such tax either has been paid or is not applicable.
 
     (e) Immediately following the Effective Time, Parent shall deliver, in

trust, to the Exchange Agent, for the benefit of the holders of Shares, (i)
certificates representing an aggregate number of shares of Parent Common Stock
as nearly as practicable equal to the product of the Exchange Ratio and the
number of Shares to be converted into Parent Common Stock as determined by this
Article II plus, if applicable, the Cash Adjustment Amount multiplied by the
number of Shares to be converted into Parent Common Stock as determined by this
Article II or (ii) if the Alternative Consideration contemplated by Section 2.2
hereof is applicable, certificates representing an aggregate number of shares of
Parent Common Stock as nearly as practicable equal to the product of the
Adjusted Exchange Ratio and the number of Shares to be converted into Parent
Common Stock as determined by this Article II, plus an amount of cash equal to
the product of the Adjusted Alternative Cash Consideration and the number of
Shares to be converted into the Adjusted Alternative Cash Consideration pursuant
to this Article II. In addition, Parent shall deliver to the Exchange Agent the
aggregate amount of any Additional Consideration to be paid to holders of
Shares. As soon as practicable after the Effective Time, each holder of Shares
converted into Parent Common Stock (plus the Cash Adjustment Amount, if
applicable or any Additional Consideration, if applicable) or cash pursuant to
this Article II, upon surrender to the Exchange Agent of one or more
Certificates for such Shares for cancellation, shall be entitled to receive
either certificates representing the number of shares of Parent Common Stock
into which such Shares shall have been converted in the Merger (plus the Cash
Adjustment Amount, if applicable, or any Additional Consideration, if
applicable) or, in case the Alternative Consideration contemplated by Section
2.2 is applicable the cash (including any Additional Consideration, if
applicable) and certificates representing the number of shares of Parent Common
Stock into which such Shares shall have been converted in the Merger. No
dividends or distributions that have been declared will be paid to persons
entitled to receive certificates for shares of Parent Common Stock until such
persons surrender their Certificates for Shares, at which time all such
dividends shall be paid. In no event shall the persons entitled to receive such
dividends be entitled to receive interest on such dividends. Notwithstanding the
foregoing, neither the Exchange Agent nor any party hereto shall be liable to a
holder of Shares for any Parent Common Stock, Alternative Consideration or
dividends thereon delivered to a public official pursuant to any applicable
abandoned property, escheat or similar law.
 
     (f) At any time following nine months after the Effective Time, the
Surviving Corporation shall be entitled to require the Exchange Agent to deliver
to it any shares of Parent Common Stock or funds (including any interest
received with respect thereto) which had been made available to the Exchange
Agent and which have not
 
                                      A-8
<PAGE>
been disbursed to holders of Certificates, and thereafter such holders shall be
entitled to look to the Surviving Corporation and Parent (subject to abandoned
property, escheat or other similar laws) only with respect to the Merger
Consideration payable or issuable upon due surrender of their Certificates,
without any interest thereon.
 
     Section 2.4 Treatment of Stock Options.  (a) Effective as of the Effective
Time, each option granted by the Company to purchase shares of Company Common
Stock that is outstanding and unexercised immediately prior thereto (the

'Company Stock Options'), shall cease to represent a right to acquire shares of
Company Common Stock and shall be converted automatically into an option to
purchase shares of Parent Common Stock in an amount and at an exercise price
determined as provided below (and otherwise subject to the terms of the Company
1992 Long-Term Incentive Compensation Plan, as amended and the Company 1992
Non-Employee Directors' Stock Option Plan, as amended (together the 'Option
Plans'), and the agreements evidencing grants thereunder). The number of shares
of Parent Common Stock subject to, and the option price and terms and conditions
of, the new option shall be determined in a manner that preserves both (i) the
aggregate gain (or loss) on the Company Stock Option immediately prior to the
Effective Time and (ii) the ratio of the exercise price per share subject to the
Company Stock Option to the fair market value (determined immediately prior to
the Effective Time) per share subject to such option, provided that any
fractional shares of Parent Common Stock resulting from such determination shall
be rounded down to the nearest share. Effective as of the Effective Time, the
Surviving Corporation shall assume each Company Stock Option agreement, each as
amended, as provided herein. The adjustment provided herein with respect to any
Company Stock Options that are 'incentive stock options' (as defined in section
422 of the Code) shall be and is intended to be effected in a manner that is
consistent with section 424(a) of the Code. The duration, vesting and other
terms of the new options shall be the same as the Company Stock Options that
they replace, except that all references to the Company shall be deemed to be
references to Parent. In the event that a holder of a Company Stock Option is
terminated without Cause (as defined in Section 5.5(a) of this Agreement) within
12 months of the Effective Time, then such holder's new option shall become 100%
exercisable as of such date of termination.
 
     (b) Notwithstanding Section 2.4(a) above, outstanding vested options under
the Long Term Incentive Plan (LTIP) held by Covered Executives (as defined in
Section 5.5(a) hereof), including options that become vested in connection with
a 'Change in Control' under the terms of existing award agreements under the
LTIP, shall, effective as of the Effective Time become exercisable under a
cashless exercise procedure made available by the Company (subject to applicable
law and any administrative procedures and policies deemed appropriate by the
Company). Individuals subject to Section 16 of the Exchange Act shall be
provided with a cash compensation arrangement providing such individuals with
the opportunity to receive a cash payment approximating the benefits that would
be deprived by reason of Section 16 of the Exchange Act.
 
     (c) Effective as of the Effective Time, the Options Plans shall terminate
and the provisions in any other plan, program, agreement or arrangement,
providing for the issuance or grant of any other interest in respect of the
capital stock of the Company or any of its Subsidiaries shall be deleted.
Furthermore, the Company shall take all actions necessary to ensure that
following the Effective Time, no holder of Company Stock Options or any
participant in the Option Plans or any other plans, programs, agreements or
arrangements shall have any right thereunder to acquire any equity securities of
the Company, the Surviving Corporation or any subsidiary of either of the
foregoing.
 
     Section 2.5 Stock Transfer Books.  At the Effective Time, the stock
transfer books of the Company shall be closed and there shall be no further
registration of transfers of Shares on the records of the Company. If, after the
Effective Time, Certificates representing Shares are presented to the Surviving

Corporation, they shall be cancelled and exchanged for cash or certificates
representing Parent Common Stock pursuant to this Article II.
 
     Section 2.6 Dissenting Shares.  Notwithstanding anything in this Agreement
to the contrary, in the event the Alternative Consideration or any Additional
Consideration contemplated by Section 2.2 hereof is applicable or in the event
that Parent elects to pay any Cash Adjustment Amount, Shares which immediately
prior to the Effective Time are held by stockholders who have properly exercised
and perfected appraisal rights under Section 262 of the DGCL (the 'Dissenting
Shares'), shall not be converted into the right to receive the Merger
Consideration, but the holders of Dissenting Shares shall be entitled to receive
such consideration as shall be determined pursuant to Section 262 of the DGCL;
provided, however, that if any such holder shall have failed to perfect or shall
withdraw or lose his right to appraisal and payment under the DGCL, such
holder's Shares shall thereupon be deemed to have been converted as of the
Effective Time into the right to receive the Merger Consideration, without any
interest thereon, and such Shares shall no longer be Dissenting Shares.

                                  ARTICLE III
                 REPRESENTATIONS AND WARRANTIES OF THE COMPANY
 
     The Company represents and warrants to Parent and Sub as follows:
 
     Section 3.1 Organization.  Each of the Company and its Subsidiaries is a
corporation, partnership or other entity duly organized, validly existing and in
good standing under the laws of the jurisdiction of its incorporation or
organization, and has all requisite corporate or other power and authority and
all necessary governmental approvals to own, lease and operate its properties
and to carry on its business as now being conducted, except where the failure to
be so organized, existing and in good standing or to have such power, authority
and governmental approvals would not have a material adverse effect on the
Company and its Subsidiaries taken as a whole. Each of the Company and its
Subsidiaries is duly qualified or licensed to do business and in good standing
in each jurisdiction in which the property owned, leased or operated by it or
the nature of the business conducted by it makes such qualification or licensing
necessary, except where the failure to be so duly qualified or licensed and in
good standing would not, in the aggregate, have a material adverse effect on the
Company and its Subsidiaries taken as a whole. As used in this Agreement, the
word 'Subsidiary' means, with respect to any party, any corporation or other
organization, whether incorporated or unincorporated, of which (i) such party or
any other Subsidiary of such party is a general partner (excluding such
partnerships where such party or any Subsidiary of such party do not have a
majority of the voting interest in such partnership) or (ii) at least a majority
of the securities or other interests having by their terms ordinary voting power
to elect a majority of the Board of Directors or others performing similar
functions with respect to such corporation or other organization is directly or
indirectly owned or controlled by such party or by any one or more of its
Subsidiaries, or by such party and one or more of its Subsidiaries. As used in
this Agreement, any reference to any event, change or effect having a material
adverse effect on or with respect to any entity (or group of entities taken as a
whole) means such event, change or effect, individually or in the aggregate with

such other events, changes, or effects, which is materially adverse to the
financial condition, business, results of operations, assets, liabilities,
properties or prospects of such entity. If 'material adverse effect' is used
with respect to more than one entity, it shall mean such events, changes or
effects with respect to all such entities taken as a whole. Section 3.1 of the
Disclosure Schedule delivered by the Company to Parent on or prior to the date
hereof (the 'Company Disclosure Schedule') sets forth a complete list of the
Company's Subsidiaries.
 
     Section 3.2 Capitalization.  (a) The authorized capital stock of the
Company consists of 100,000,000 Shares and 25,000,000 shares of preferred stock,
par value $.01 per share (the 'Preferred Stock'). As of the date hereof, (i)
66,587,990 shares of Company Common Stock are issued and outstanding, 700,000
shares of Company Common Stock are held in the Company's treasury, 1,096,101

the Company of this Agreement and the Stock Option Agreement, and the
consummation by it of the transactions contemplated hereby and thereby. This
Agreement and the Stock Option Agreement has been duly executed and delivered by
the Company and, assuming this Agreement and the Stock Option Agreement
constitutes a valid and binding obligation of Parent and Sub, constitutes a
valid and binding obligation of the Company enforceable against the Company in
accordance with its terms, except that (i) such enforcement may be subject to

                                      A-11

Option Agreement, nor the consummation by the Company of the transactions
contemplated hereby or thereby nor compliance by the Company with any of the
provisions hereof or thereof will (i) conflict with or result in any breach of
any provision of the certificate of incorporation or by-laws or similar
organizational documents of the Company or of any of its Subsidiaries, (ii)
require any filing with, or permit, authorization, consent or approval of, any
court, arbitral tribunal, administrative agency or commission or other
governmental or other regulatory authority or agency (a 'Governmental Entity'),
except where the failure to obtain such permits, authorizations, consents or
approvals or to make such filings would not have a material adverse effect on
the Company and its Subsidiaries and would not, or would not be reasonably
likely to, materially impair the consummation of the Offer or the Zell/Chilmark
Stockholder Agreement or the Stock Option Agreement or the ability of the
Company to consummate the Merger or the other transactions contemplated hereby
or thereby, (iii) result in a violation or breach of, or constitute (with or
without due notice or lapse of time or both) a default (or give rise to any

guarantee, other evidence of indebtedness (collectively, the 'Debt
Instruments'), lease, license, contract, agreement or other instrument or
obligation to which the Company or any of its Subsidiaries is a party or by
which any of them or any of their properties or assets may be bound and which
either has a term of more than one year or involves the payment or receipt of
money in excess of $300,000 (a 'Company Agreement') or (iv) violate any order,
writ, injunction, decree, statute, rule or regulation applicable to the Company,
any of its Subsidiaries or any of their properties or assets, except in the case
of clause (iii) or (iv) for such violations, breaches or defaults which would
not, individually or in the aggregate, have a material adverse effect on the
Company and its Subsidiaries, and which would not, or would not be reasonably
likely to, materially impair the consummation of the Offer, the Stock Option
Agreement or the Zell/Chilmark Stockholder Agreement or the ability of the
Company to consummate the Merger or the other transactions contemplated hereby
or thereby.
 
     Section 3.5 SEC Reports and Financial Statements.  The Company has filed

with the SEC, and has heretofore made available to Parent true and complete
copies of, all forms, reports, schedules, statements and other documents
required to be filed by it and its Subsidiaries since May 30, 1992 under the
Exchange Act or the Securities Act (as such documents have been amended since
the time of their filing, collectively, the 'Company SEC Documents'). As of
their respective dates or, if amended, as of the date of the last such
amendment, the Company SEC Documents, including, without limitation, any
financial statements or schedules included therein (a) did not contain any
untrue statement of a material fact or omit to state a material fact required to
be stated therein or necessary in order to make the statements therein, in light
of the circumstances under which they were made, not misleading and (b) complied
in all material respects with the applicable requirements of the Exchange Act
and the Securities Act, as the case may be, and the applicable rules and
regulations of the SEC thereunder. Each of the consolidated financial statements
included in the Company SEC Documents have been prepared from, and are in
accordance with, the books and records of the Company and/or its consolidated
Subsidiaries, comply in all material respects with applicable accounting
requirements and with the published rules and regulations of the SEC with
respect thereto, have been prepared in accordance with United States generally
accepted accounting principles ('GAAP') applied on a consistent basis during the
periods involved (except as may be indicated in the notes thereto) and fairly
present in all material respects the consolidated financial position and the
consolidated results of operations and cash flows (and changes in financial
position, if any) of the Company and its consolidated Subsidiaries as at the
dates thereof or for the periods presented therein.
 
     Section 3.6 Absence of Certain Changes.  Except to the extent disclosed in
the Company SEC Documents filed prior to the date of this Agreement or as
otherwise disclosed to Parent in Section 3.6 of the Company Disclosure Schedule,
from June 3, 1995 through the date of this Agreement, the Company and its
Subsidiaries have conducted their respective businesses and operations in the
ordinary course of business consistent with past practice. From June 3, 1995
through the date of this Agreement, there has not occurred (i) any events,
changes, or effects (including the incurrence of any liabilities of any nature,
whether or not accrued, contingent or otherwise) having or, which would be
reasonably likely to have, individually or in the aggregate, a material adverse
effect on the Company and its Subsidiaries; (ii) any declaration, setting aside
or payment of any dividend or other distribution (whether in cash, stock or
property) with respect to the equity interests of the Company or of any of its
Subsidiaries, other than dividends paid by wholly owned Subsidiaries; or (iii)
any material change by the Company or any of its Subsidiaries in accounting
principles or methods, except insofar as may be required by a
 
                                      A-12
<PAGE>
change in GAAP. Except as set forth on Schedule 3.6 of the Company Disclosure
Schedule, from June 3, 1995 through the date of this Agreement, neither the
Company nor any of its Subsidiaries has taken any of the actions prohibited by
Section 5.1 hereof.
 
     Section 3.7 No Undisclosed Liabilities.  Except (a) to the extent disclosed
in the Company SEC Documents filed prior to the date of this Agreement and (b)
for liabilities and obligations incurred in the ordinary course of business
consistent with past practice, during the period from June 3, 1995 through the

date of this Agreement, neither the Company nor any of its Subsidiaries have
incurred any liabilities or obligations of any nature, whether or not accrued,
contingent or otherwise, that have, or would be reasonably likely to have, a
material adverse effect on the Company and its Subsidiaries or would be required
to be reflected or reserved against on a consolidated balance sheet of the
Company and its Subsidiaries (including the notes thereto) prepared in
accordance with GAAP as applied in preparing the June 3, 1995 consolidated
balance sheet of the Company and its Subsidiaries. Section 3.7 of the Company
Disclosure Schedule sets forth each instrument evidencing indebtedness of the
Company and its Subsidiaries which will accelerate or become due or payable, or
result in a right of redemption or repurchase on the part of the holder of such
indebtedness, or with respect to which any other payment or amount will become
due or payable, in any such case with or without due notice or lapse of time, as
a result of this Agreement, the Merger or the other transactions contemplated
hereby.
 
     Section 3.8 Information in Proxy Statement/Prospectus.  The Proxy
Statement/Prospectus (or any amendment thereof or supplement thereto), at the
date mailed to the Company's stockholders, on the date filed with the SEC and at
the time of the Special Meetings, will not contain any untrue statement of a
material fact or omit to state any material fact required to be stated therein
or necessary in order to make the statements therein, in light of the
circumstances under which they are made, not misleading, provided, however, that
no representation is made by the Company with respect to statements made therein
based on information supplied by Parent or Sub for inclusion in the Proxy
Statement/Prospectus. None of the information supplied by the Company for
inclusion or incorporation by reference in the Registration Statement will, at
the date it becomes effective and at the time of the Special Meetings contain
any untrue statement of a material fact or omit to state any material fact
required to be stated therein or necessary in order to make the statements
therein, in light of the circumstances under which they are made, not
misleading. Subject to the proviso set forth in the second preceding sentence,
the Proxy Statement/Prospectus will comply in all material respects with the
provisions of the Exchange Act and the rules and regulations thereunder.

compensation, bonus, stock option, stock appreciation rights and stock purchase
plans) of any type (including but not limited to plans described in section 3(3)
of the Employee Retirement Income Security Act of 1974, as amended ('ERISA')),
maintained by the Company, any of its Subsidiaries or any trade or business,
whether or not incorporated (an 'ERISA Affiliate'), that together with the

4001(a)(14) of ERISA, or with respect to which the Company or any of its
Subsidiaries has or may have a liability, other than those listed on Section
3.9(a) of the Company Disclosure Schedule (the 'Benefit Plans'). Except as

amendment, modification to, or adoption of, any Benefit Plan. Section 3.9(a) of
the Company Disclosure Schedule contains a list of each material employment,
termination, severance, incentive and deferred compensation agreement or
arrangement that is a Benefit Plan, and the date of execution of each such
agreement or arrangement.
 
     (b) Except as disclosed in Section 3.9(b) of the Company Disclosure
Schedule, under the applicable laws of all jurisdictions within the United
States of America and all foreign jurisdictions, with respect to any Benefit

3.9(c) of the Company Disclosure Schedule and as would not have a material
adverse effect on the Company and its Subsidiaries: (i) if intended to qualify

been satisfied in full except as would not have or would not reasonably be
likely to have a material adverse effect on the Company and its Subsidiaries
(including sections 4063-4064 and 4069 of ERISA) and, to the knowledge of the
Company, no basis for any such liability exists; (ii) neither the Company nor
any ERISA Affiliate maintains (or contributes to), or has maintained (or has
contributed to) within the last six years, any employee benefit plan that is
subject to Title IV of ERISA; and (iii) there is no pending dispute between the
Company or any ERISA Affiliate concerning payment of contributions or payment of
withdrawal liability payments.
 
     (f) With respect to each Benefit Plan that is a 'welfare plan' (as defined
in section 3(1) of ERISA), except as specifically disclosed in Section 3.9(f) of
the Company Disclosure Schedule, no such plan provides medical or death benefits
with respect to current or former employees of the Company or any of its
Subsidiaries beyond their termination of employment, other than on an
employee-pay-all basis, and each such welfare plan may be amended or terminated
by the Company or any of its Subsidiaries at any time with respect to such

former or current employees.

the material requirements for the receipt of such special tax treatment since

increase the amount, of compensation or benefits due to any individual with
respect to any Benefit Plan, or (ii) constitute or result in a prohibited
transaction under section 4975 of the Code or section 406 or 407 of ERISA with
respect to any Benefit Plan.
 
     (i) Except as disclosed on Section 3.9(i) of the Company Disclosure
Schedule, neither the Company, any Benefits Affiliate nor any 'administrator' as
that term is defined in section 3(16) of ERISA, has any liability with respect
to or connected with any Benefit Plan for excise taxes payable under the Code or
civil penalties payable under ERISA and, to the Company's knowledge, no basis
for any such liability exists.
 
     (j) Except as disclosed on Schedule 3.9(j) of the Company Disclosure

     (l) With respect to each Benefit Plan that is a 'group health plan' as such
term is defined in section 5000(b) of the Code, except as specifically set forth
in Section 3.9(l) of the Company Disclosure Schedule, to the Company's
knowledge, each such Benefit Plan complies and has complied with the
requirements of Part 6 of Title I of ERISA and Sections 4980B and 5000 of the
Code except where the failure to so comply would not have a material adverse
effect on the Company and its Subsidiaries.
 
     (m) There are no material plans, arrangements, practices, contracts or

to a director or former director (as a director) of the Company or an ERISA
Affiliate other than those listed on Section 3.9(m) of the Company Disclosure
Schedule or disclosed in the Company's most recent proxy statement (the

     Parent and Sub represent and warrant to the Company as follows:
 
     Section 4.1 Organization.  Each of Parent and Sub is a corporation duly
organized, validly existing and in good standing under the laws of Delaware and
has all requisite corporate or other power and authority and all necessary
governmental approvals to own, lease and operate its properties and to carry on
its business as now being conducted, except where the failure to be so
organized, existing and in good standing or to have such power, authority and
governmental approvals would not have a material adverse effect on Parent and
its Subsidiaries. Parent and each of its Subsidiaries is duly qualified or
licensed to do business and in good standing in each jurisdiction in which the
property owned, leased or operated by it or the nature of the business conducted
by it makes such qualification or licensing necessary, except where the failure
to be so duly qualified or licensed and in good standing would not have a
material adverse effect on Parent and its Subsidiaries.
 
     Section 4.2 Capitalization.  (a) The authorized capital stock of Parent
consists of 240,000,000 shares of Parent Common Stock and (b) 20,000,000

outstanding, (ii) no shares of Parent Preferred Stock are issued and
outstanding, (iii) 6,532,169 shares of Parent Common Stock are issued and held

reserved for issuance under Parent's 1990 Omnibus Stock Incentive Plan (the

all shares which may be issued pursuant to the exercise of outstanding options
or pursuant to the Parent Plan will be, when issued in accordance with the
respective terms thereof, duly authorized, validly issued, fully paid and
non-assessable. Except for Parent's 6.75% Zero Coupon Convertible Subordinated
Notes due July 24, 2006, there are no bonds, debentures, notes or other
indebtedness having voting rights (or convertible into securities having such

contemplated by this Agreement, as of the date hereof, (i) there are no shares
of capital stock of Parent authorized, issued or outstanding and (ii) there are
no existing options, warrants, calls, preemptive rights, subscriptions or other
rights, convertible securities, agreements, arrangements or commitments of any
character, relating to the issued or unissued capital stock of Parent or any of
its Subsidiaries, obligating Parent or any of its Subsidiaries to issue,
transfer or sell or cause to be issued, transferred or sold any shares of
capital stock or Parent Voting Debt of, or other equity interest in, Parent or
any of its Subsidiaries or securities convertible into or exchangeable for such
shares or equity interests or obligations of Parent or any of its Subsidiaries
to grant, extend or enter into any such option, warrant, call, subscription or
other right, convertible security, agreement, arrangement or commitment. There
are no outstanding contractual obligations of Parent or any of its Subsidiaries
to repurchase, redeem or otherwise acquire any shares of Parent Common Stock or

provide funds to make any investment (in the form of a loan, capital
contribution or otherwise) in any Subsidiary or any other entity.

capital stock of Parent, or any of its Subsidiaries, respectively, as a result
of the transactions contemplated by this Agreement.
 
     Section 4.3 Corporate Authorization; Validity of Agreement; Necessary
Action.  Each of Parent and Sub has full corporate power and authority to
execute and deliver this Agreement, the Stock Option Agreement and the
Zell/Chilmark Stockholder Agreement and, subject in the case of this Agreement
to obtaining any necessary approval of Parent's stockholders as contemplated by
Section 1.7(b) hereof with respect to the Merger, to consummate the transactions
contemplated hereby and thereby. The execution, delivery and performance by
Parent and Sub of this Agreement and the consummation by Parent and Sub of the
transactions contemplated hereby have been duly and validly authorized by their
respective Boards of Directors and by Sub's sole stockholder and, except in the
case of obtaining any necessary approval of Parent's stockholders as
contemplated by Section 1.7(b) hereof, no other corporate action or proceedings
on the part of Parent and Sub are necessary to authorize the execution and
delivery by Parent and Sub of this Agreement and the consummation by Parent and
 
                                      A-18
<PAGE>
Sub of the transactions contemplated hereby. This Agreement has been duly
executed and delivered by Parent and Sub, and, assuming this Agreement
constitutes valid and binding obligations of the Company, constitutes valid and
binding obligations of each of Parent and Sub, enforceable against them in
accordance with its terms, except that (i) such enforcement may be subject to
applicable bankruptcy, insolvency or other similar laws, now or hereafter in
effect, affecting creditors' rights generally, and (ii) the remedy of specific
performance and injunctive and other forms of equitable relief may be subject to
equitable defenses and to the discretion of the court before which any

other applicable requirements of, the Exchange Act, the Securities Act of 1933
(the 'Securities Act'), the DGCL, the HSR Act, state blue sky laws and any
applicable state takeover laws and the approval by Parent's stockholders of the
issuance of Parent Common Stock in the Merger, neither the execution, delivery
or performance of this Agreement by Parent and Sub nor the consummation by
Parent and Sub of the transactions contemplated hereby nor compliance by Parent
and Sub with any of the provisions hereof will (i) conflict with or result in
any breach of any provision of the certificate of incorporation or by-laws of
Parent and Sub, (ii) require any filing with, or permit, authorization, consent
or approval of, any Governmental Entity (except where the failure to obtain such
permits, authorizations, consents or approvals or to make such filings would not
have a material adverse effect on Parent and its Subsidiaries or would not, or
would not be reasonably likely to, materially impair the ability of Parent and
Sub to consummate the Offer, the Merger or the other transactions contemplated
hereby or thereby), (iii) result in a violation or breach of, or constitute
(with or without due notice or lapse of time or both) a default (or give rise to
any right of termination, amendment, cancellation or acceleration) under, any of
the terms, conditions or provisions of any note, bond, mortgage, indenture,
guarantee, other evidence of indebtedness, lease, license, contract, agreement
or other instrument or obligation to which Parent or any of its Subsidiaries is
a party or by which any of them or any of their properties or assets may be
bound or (iv) violate any order, writ, injunction, decree, statute, rule or
regulation applicable to Parent, any of its Subsidiaries or any of their
properties or assets, except in the case of clauses (iii) and (iv) for

on Parent and its Subsidiaries or would not, or would not be reasonably likely
to, materially impair or the ability of Parent or Sub to consummate the Offer,
the Merger or the other transactions contemplated hereby.

the SEC, and has heretofore made available to the Company, true and complete
copies of, all forms, reports, schedules, statements and other documents
required to be filed by it and its Subsidiaries since February 27, 1993 under
the Exchange Act or the Securities Act (as such documents have been amended

or effects (including the incurrence of any liabilities of any nature, whether
or not accrued, contingent or otherwise) having or, which would be reasonably
likely to have, individually or in the aggregate, a material adverse effect on
Parent and its Subsidiaries; (ii) any declaration, setting aside or payment of
any dividend or other distribution (whether in cash, stock or property) with

material fact required to be stated therein or necessary in order to make the
statements therein, in light of the circumstances under which they are made, not
misleading, provided, however, that no representation is made by Parent or Sub
with respect to statements made therein based on information supplied by the
Company for inclusion in the Registration Statement. None of the information
supplied by Parent or Sub for inclusion or incorporation by reference in the
Proxy Statement/Prospectus will, at the date mailed to stockholders and at the
time of the Special Meetings, contain any untrue statement of a material fact or

Company's judgment reasonably may facilitate obtaining any final order or orders

     (c) Each of the Company, Parent and Sub will take all reasonable actions
necessary to comply promptly with all legal requirements (which actions shall
include, without limitation, furnishing all information in connection with
approvals of or filings with any Governmental Entity, including, without
limitation, any schedule, or reports
 
                                      A-24
<PAGE>
required to be filed with the SEC), and will promptly cooperate with and furnish
information to each other in connection with any such requirements imposed upon
any of them or any of their Subsidiaries in connection with this Agreement and
the transactions contemplated hereby. Each of the Company, Parent and Sub will,
and will cause its Subsidiaries to, take all reasonable actions necessary to
obtain any consent, authorization, order or approval of, or any exemption by,
any Governmental Entity or other public or private third party, required to be
obtained or made by Parent, Sub, the Company or any of their Subsidiaries in
connection with the Offer, the Merger or the taking of any action contemplated

     Section 5.5 Employee Benefits.  (a) Parent agrees to cause Surviving
Corporation and its Subsidiaries to provide to certain employees of the Company
payments and benefits, which are set forth in this Section 5.5(a) and which
shall be effected, by means of individual agreements, negotiated in good faith
by the parties hereto, reflecting the economic terms set forth in this Section
5.5.
 
     (i) EVA Plan Bonus
 

     As soon as practicable following the earlier of (A) the Effective Time and
(B) the end of the Company's 1996 fiscal year, the Company shall pay, pursuant
to the terms of the Company's Economic Value Added Incentive Plan (the 'EVA
Plan') as herein modified, bonuses for fiscal year 1996, calculated based on the
Company's financial results as of February 10, 1996, and annualized to equal a
bonus for a 12 month period.
 
     (ii) Severance Pay
 
     With respect to the executives of the Company listed on Schedule 5.5(a)(ii)
attached hereto ('Covered Executives'), effective as soon as practicable
following the Effective Time (or if later, the date of termination of employment
of the Covered Executive), the Company shall pay to each Covered Executive
severance payments (the 'Severance Payments'), on a bi-weekly basis or at such
other intervals as are consistent with Parent's executive payroll practices,
based on one of the two formulae set forth below, pursuant to elections made by
each Covered Executive prior to the Effective Time:
 
          (A) Severance Payments equal to, on an annualized basis, 'Base Pay'
     (as defined below), continuing for a period of three years with respect to
     Covered Executives who are listed as Group A Executives ('Group A
     Executives') on Schedule 5.5(a)(ii)(A) of the Company Disclosure Schedule
     and for a period of 18 months with respect to Covered Executives listed as
     Group B Executives ('Group B Executives') on Schedule 5.5(a)(ii)(A) of the
     Company Disclosure Schedule. For purposes of this Section 5.5(a), Base Pay
     shall mean the highest base pay paid to the Covered Executive during any
     one of the 1994, 1995 or 1996 fiscal years, provided that the base pay for
     the 1996 fiscal year shall be calculated on an annualized basis; or
 
          (B) Severance Payments equal to, on an annualized basis, 'Base Plus
     Bonus Pay' (as defined below), continuing for a period of two years with
     respect to Group A Executives, and for a period of one year with respect to
     Group B Executives. For purposes of this Section 5.5(a), Base Plus Bonus
     Pay shall mean Base Pay plus the amount that would have been paid to the
     executive under the EVA Plan for fiscal year 1995 as the targeted bonus
     (the '1995 Target Bonus').
 
     In lieu of the Severance Payments described in clauses (A) and (B) above,
Messrs. Hoven and Mastrian shall receive Severance Payments, continuing for
three years, equal to, on an annualized basis, Base Plus Bonus Pay.
 
     The period during which a Covered Executive continues to receive Severance
Payments shall be referred to in this Section 5.5(a) as the 'Severance Period'
for such Covered Executive.
 
     During the Severance Period, each Covered Executive shall continue to
receive, at the Company's expense, continuation of benefits described in Section
6(a)(ii) of the Covered Executive's employment agreement with the Company on
terms at least as favorable to the Covered Executive as is currently in effect,
which benefits may be provided by covering such Covered Executive under benefit
plans and programs maintained by Parent provided, further however, that to the
extent any such Covered Executive receives comparable benefits from, and at the
expense of, a subsequent employer, such benefits from the Company shall cease.
 

     Notwithstanding anything in this Agreement to the contrary, the Severance
Payments described in clauses (A) or (B) above shall be paid to a Covered
Executive only if such Covered Executive is actively employed by the Company
immediately prior to the Effective Time.
 
                                      A-25
<PAGE>
     In the event that a Covered Executive that continues employment with the
Company following the Effective Time is terminated prior to the expiration of
the Severance Period that would have applied had such Covered Executive been
terminated effective as of the Effective Time, then such Covered Executive shall
be entitled to receive the Severance Payments determined pursuant to this
Section 5.5(a).
 
     Each employee, other than any Covered Executives, of the Company, who is
covered by the Company's severance pay plan as in effect on November 1, 1995
(each, a 'Severance-Eligible Employee') and who is employed by the Company
immediately prior to the Effective Time and terminated for other than 'Cause,'
as defined below, within 12 months following the Effective Time, shall be
entitled to receive bi-weekly severance payments, consistent with Parent's
payroll practices, for a six-month period commencing on such Severance-Eligible
Employee's date of termination of employment, equal to, on an annualized basis,
such Severance-Eligible Employee's Base Pay; provided, however, that such
payments shall be reduced (but not below zero), by the amount of compensation
such Severance-Eligible Employee receives from a subsequent employer to the
extent that such Severance-Eligible Employee is employed during such six-month
period.
 
     For purposes of this Agreement, 'Cause' shall mean the conviction of an
employee or executive (as the case may be) for the commission of a felony,
including the entry of a guilty or nolo contendere plea, any willful, grossly
negligent or fraudulent action or inaction by an employee or executive, as the
case may be, or the employee's or executive's willful and continued failure to
substantially perform an employee's or executive's assigned duties.
 
     (iii) SERP Benefits
 
     Each Company employee who is (A) covered by the Company's Supplemental
Executive Retirement Plan ('SERP') and (B) actively employed by the Company, in
either case, immediately prior to the Effective Time (each, a 'SERP Executive')
shall be eligible to receive benefits under the SERP based on the terms of the
SERP, as modified herein. For each SERP Executive (i) the amount of service
taken into account for purposes of calculating benefits and vesting under the
SERP shall be equal to the SERP Executive's service with the Company prior to
the Effective Time plus the Covered Executive's Severance Period, if any, and
(ii) compensation for each SERP Executive for purposes of the SERP shall include
one-half of the 1995 Target Bonus for such SERP Executive.
 
     (iv) Gross-Up; Cap
 
     With respect to the eight Executives listed on Section 5.5(a)(iv) of the
Company Disclosure Schedule, the Company shall provide such executives with a
cash gross-up payment to make such executives whole for the excise taxes imposed
on all benefits and other amounts paid or payable to such executive on account

of the transactions contemplated by this Agreement as a result of the
application of sections 280G and 4999 of the Code. With respect to all other
employees of the Company who are entitled to benefits and other amounts paid or
payable to such executive on account of the transactions contemplated by this
Agreement as a result of the application of sections 280G and 4999 of the Code,
the Company shall not be obligated to pay or provide to any such employee any
payments or benefits to the extent that such payments or benefits would
constitute a 'parachute payment' within the meaning of section 280G(b)(2)(A) of
the Code.
 
     (v) ESPP
 
     The Company shall amend the Company's Employee Stock Purchase Plan to
provide that the option period that is in effect as of the date hereof shall
cease as soon as practicable following the date hereof.
 
     (vi) Outplacement
 
     The Company shall provide outplacement services from a recognized
outplacement provider selected by Parent to all employees of the Company as of
the Effective Time who were based in Twinsburg, Ohio as of the Effective Time,
and are terminated without Cause within one year of the Effective Time.
 
     (b) Parent agrees to cause Surviving Corporation and its Subsidiaries to
provide to all active employees of the Company who continue to be employed by
the Company as of the Effective Time ('Continuing Employees') employee benefits
comparable to those benefits provided to similarly situated employees of Parent
(which benefits may be provided by covering Company employees under benefit
plans maintained by Parent for
 
                                      A-26
<PAGE>
employees of Parent who perform similar duties). In addition, with respect to
medical benefits provided to Continuing Employees as of the Effective Time,
Parent agrees to cause Surviving Corporation and its Subsidiaries to waive
waiting periods and pre-existing condition requirements under such plans, and to
give Continuing Employees credit for any copayments and deductibles actually
paid by such employees under the Company's medical plans during the calendar
year in which the Closing occurs. In addition, service with the Company shall be
recognized for purposes of eligibility under Parent welfare plans as well as for
purposes of Parent's programs or policies for vacation pay and sick pay.
 
     Section 5.6 No Solicitation.  (a) The Company (and its Subsidiaries, and
affiliates over which it exercises control) will not, and the Company (and its
Subsidiaries, and affiliates over which it exercises control) will use their
best efforts to ensure that their respective officers, directors, employees,
investment bankers, attorneys, accountants and other agents do not, directly or
indirectly: (i) initiate, solicit or encourage, or take any action to facilitate
the making of, any offer or proposal which constitutes or is reasonably likely
to lead to any Takeover Proposal (as defined below) of the Company or any
Subsidiary or an inquiry with respect thereto, or, (ii) in the event of an
unsolicited Takeover Proposal for the Company or any Subsidiary or affiliate of
the Company, engage in negotiations or discussions with, or provide any
information or data to, any corporation, partnership, person or other entity or

group (other than Parent, any of its affiliates or representatives) (each, a
'Person') relating to any Takeover Proposal, except in the case of clause (ii)
above to the extent that (x) the Takeover Proposal is a bona fide written
proposal submitted to the Company's Board of Directors and (y) the Company's
Board of Directors determines, after having received the oral or written opinion
of outside legal counsel to the Company, that the failure to engage in such
negotiations or discussions or provide such information would result in a breach
of the Board of Directors' fiduciary duties under applicable law. The Company
shall notify Parent and Sub orally and in writing of any such offers, proposals,
inquiries or Takeover Proposals (including, without limitation, the material
terms and conditions thereof and the identity of the Person making it), within
24 hours of the receipt thereof, and shall thereafter inform Parent on a
reasonable basis of the status and content of any discussions or negotiations
with such a third party, including any material changes to the terms and
conditions thereof. The Company shall, and shall cause its Subsidiaries and
affiliates over which it exercises control, and will use best efforts to ensure
their respective officers, directors, employees, investment bankers, attorneys,
accountants and other agents to, immediately cease and cause to be terminated
all discussions and negotiations that have taken place prior to the date hereof,
if any, with any parties conducted heretofore with respect to any Takeover
Proposal relating to the Company. Nothing contained in this Section 5.6 shall
prohibit the Company or its Board of Directors from taking and disclosing to its
stockholders a position with respect to a tender offer by a third party pursuant
to Rules 14d-9 and 14e-2(a) promulgated under the Exchange Act or making such
disclosure as may be required by applicable law.
 
     (b) As used in this Agreement, 'Takeover Proposal' when used in connection
with any Person shall mean any tender or exchange offer involving the capital
stock of such Person, any proposal for a merger, consolidation or other business
combination involving such Person or any Subsidiary of such Person, any proposal
or offer to acquire in any manner a substantial equity interest in, or a
substantial portion of the business or assets of, such Person or any Subsidiary
of such Person, any proposal or offer with respect to any recapitalization or
restructuring with respect to such Person or any Subsidiary of such Person or
any proposal or offer with respect to any other transaction similar to any of
the foregoing with respect to such Person or any Subsidiary of such Person other
than pursuant to the transactions to be effected pursuant to this Agreement.
 
     Section 5.7 Additional Agreements.  Subject to the terms and conditions
herein provided (including, but not limited to, Section 5.4) each of the parties
hereto agrees to use its reasonable efforts to take, or cause to be taken, all
action and to do, or cause to be done, all things necessary, proper or
advisable, whether under applicable laws and regulations or otherwise, or to
remove any injunctions or other impediments or delays, legal or otherwise, to
consummate and make effective the Merger and the other transactions contemplated
by this Agreement. In case at any time after the Effective Time any further
action is necessary or desirable to carry out the purposes of this Agreement,
the proper officers and directors of the Company and Parent shall use their
reasonable efforts to take, or cause to be taken, all such necessary actions.
 
     Section 5.8 Publicity.  So long as this Agreement is in effect, neither the
Company nor Parent nor affiliates which either of them control shall issue or
cause the publication of any press release or other public statement or
announcement with respect to this Agreement, the Stock Option Agreement or the

Zell/Chilmark Stockholder
 
                                      A-27
<PAGE>
Agreement or the transactions contemplated hereby or thereby without the prior
consultation of the other party, except as may be required by law or by
obligations pursuant to any listing agreement with a national securities
exchange, provided that each party will use its best efforts to consult with the
other party prior to any such issuance.
 
     Section 5.9 Notification of Certain Matters.  The Company shall give prompt
notice to Parent, and Parent shall give prompt notice to the Company, of (a) the
occurrence, or non-occurrence of any event the occurrence or non-occurrence of
which would cause any representation or warranty contained in this Agreement to
be untrue or inaccurate in any material respect at or prior to the Effective
Time and (b) any material failure of the Company or Parent, as the case may be,
to comply with or satisfy any covenant, condition or agreement to be complied
with or satisfied by it hereunder; provided, however, that the delivery of any
notice pursuant to this Section 5.9 shall not limit or otherwise affect the
remedies available hereunder to the party receiving such notice.
 
     Section 5.10 Directors' and Officers' Insurance and
Indemnification.  Parent agrees that at all times after the Effective Time, it
shall cause the Surviving Corporation and its Subsidiaries to indemnify, each
person who is now, or has been at any time prior to the date hereof, an
employee, agent, director or officer of the Company or of any of the Company's
Subsidiaries, successors and assigns (individually an 'Indemnified Party' and
collectively the 'Indemnified Parties'), to the fullest extent permitted by law,
with respect to any claim, liability, loss, damage, judgment, fine, penalty,
amount paid in settlement or compromise, cost or expense, including reasonable
fees and expenses of legal counsel, (whenever asserted or claimed) ('Indemnified
Liability') based in whole or in part on, or arising in whole or in part out of,
any matter existing or occurring at or prior to the Effective Time whether
commenced, asserted or claimed before or after the Effective Time, including
liability arising under the Securities Act, the Exchange Act or state law.
Parent shall, and shall cause the Surviving Corporation to, maintain in effect
for not less than four years after the Effective Time the current policies of
directors' and officers' liability insurance maintained by the Company and its
Subsidiaries on the date hereof (provided that Parent may substitute therefor
policies having at least the same coverage and containing terms and conditions
which are no less advantageous to the persons currently covered by such policies
as insured) with respect to matters existing or occurring at or prior to the
Effective Time; provided, however, that if the aggregate annual premiums for
such insurance during such period shall exceed 200% of the per annum rate of the
aggregate premium currently paid by the Company and its Subsidiaries for such
insurance on the date of this Agreement, then Parent shall cause the Surviving
Corporation to, and the Surviving Corporation shall, provide the maximum
coverage that shall then be available at an annual premium equal to 200% of such
rate. Parent agrees to pay all expenses (including fees and expenses of counsel)
that may be incurred by any Indemnified Party in successfully enforcing the
indemnity or other obligations under this Section 5.10. The rights under this
Section 5.10 are in addition to rights that an Indemnified Party may have under
the Certificate of Incorporation, By-laws, other similar organizational
documents of the Company or any of its Subsidiaries or the DGCL. The rights

under this Section 5.10 shall survive consummation of the Merger and are
expressly intended to benefit each Indemnified Party. Parent agrees to cause
Surviving Corporation and any of its Subsidiaries (or their successors) to keep
in effect the provisions of its Certificate of Incorporation or By-laws or
similar organizational documents providing for indemnification to the fullest
extent provided by law.
 
     Section 5.11 Rule 145 Affiliates.  At least 40 days prior to the Closing
Date, the Company shall deliver to Parent a letter identifying, to the best of
the Company's knowledge, all persons who are, at the time of the Company Special
Meeting, deemed to be 'affiliates' of the Company for purposes of Rule 145 under
the Securities Act ('Company Affiliates'). The Company shall use its best
efforts to cause each Person who is identified as a Company Affiliate to deliver
to Parent at least 30 days prior to the Closing Date an agreement substantially
in the form of Exhibit C to this Agreement.
 
     Section 5.12 Cooperation.  Parent and the Company shall together, or
pursuant to an allocation of responsibility to be agreed upon between them,
coordinate and cooperate (a) with respect to the timing of the Special Meetings,
(b) in determining whether any action by or in respect of, or filing with, any
Governmental Entity is required, or any actions, consents approvals or waivers
are required to be obtained from parties to any material contracts, in
connection with the consummation of the transactions contemplated by this
Agreement, (c) in seeking any such actions, consents, approvals or waivers or
making any such filings, furnishing information required in connection therewith
and timely seeking to obtain any such actions, consents approvals or waivers. As
soon as possible following the commencement of the Offer, the Company shall
cooperate with Parent in the
 
                                      A-28
<PAGE>
preparation and filing of the Proxy Statement/Prospectus with the Commission,
including, but not limited to providing legal, financial, and accounting
information concerning the Company and assisting in the preparation of all
financial and pro forma financial information required to be included in such
Proxy Statement/Prospectus. Subject to the terms and conditions of this
Agreement, Parent and the Company will each use its best efforts to have the
Registration Statement declared effective under the Securities Act as promptly
as practicable after the Registration Statement is filed, and Parent and the
Company shall, subject to applicable law, confer on a regular and frequent basis
with one or more representatives of one another to report operational matters of

the consummation of the Offer, Parent and the Company shall prepare and file
with the SEC the Proxy Statement/Prospectus and each shall use its best efforts
to have the Proxy Statement/Prospectus cleared by the SEC as promptly as
practicable. As soon as practicable following such clearance Parent shall
prepare and file with the SEC the Registration Statement, of which the Proxy
Statement/Prospectus will form a part, and shall use its best efforts to have

any provision therein which in any manner limits, restricts or prohibits the
voting or acquisition of Shares by Parent or any of its affiliates or the
representation of Parent's designees on the Company's Board of Directors or
which in any manner would be inconsistent with this Agreement or the
Zell/Chilmark Stockholder Agreement or the Stock Option Agreement or the
transactions contemplated hereby and thereby shall terminate as of the date
hereof. The Company agrees not to take any action that would impede, bar,
restrict or otherwise interfere in any manner with Parent's rights under the
Zell/Chilmark Stockholder Agreement or the Stock Option Agreement, including,
without limitation, Parent's right to exercise the option granted to Parent
pursuant to the Stock Option Agreement. The provisions of this Section 5.15
shall survive any termination of this Agreement.
 
     Section 5.16 Stock Exchange Listing.  The Parent shall use its best efforts

('NYSE') and the Pacific Stock Exchange, subject to official notice of issuance,

     Section 7.1 Termination.  Anything herein or elsewhere to the contrary
notwithstanding, this Agreement may be terminated and the Merger contemplated
herein may be abandoned at any time prior to the Effective Time, whether before
or after stockholder approval hereof:
 
          (a) By the mutual consent of the Board of Directors of Parent and the
     Board of Directors of the Company.
 
          (b) By either of the Board of Directors of the Company or the Board of
     Directors of Parent:
 
              (i) if Parent or Sub has not purchased Shares in accordance with
        the terms of the Offer on or prior to April 29, 1996; provided, however,
        that the right to terminate this Agreement under this Section 7.1(b)(i)
        shall not be available to any party whose failure to fulfill any
        obligations under this Agreement has been the cause of, or resulted in,
        the failure to satisfy the conditions to the Offer; provided further,
        however, that Parent shall not have the right to terminate this
        Agreement under this Section 7.1(b)(i) if Parent or Sub purchases any
        Shares in connection with the Offer after April 29, 1996; or
 
             (ii) if any Governmental Entity shall have issued an order, decree

        the transactions contemplated by this Agreement and such order, decree,
        ruling or other action shall have become final and non-appealable.
 
          (c) By the Board of Directors of the Company:
 
              (i) if, prior to the purchase of Shares pursuant to the Offer, the
        Board of Directors of the Company shall have (A) withdrawn, or modified

        approve and permit the Company to execute a definitive agreement

        relating to a Takeover Proposal, and (B) determined, after having
        received the oral or written opinion of outside independent legal
        counsel to the Company, that the failure to take such action as set
        forth in the preceding clause (A) would result in a breach of the Board
        of Directors' fiduciary duties under applicable law; provided, however,
        that the Company shall have given Parent and Sub at least thirty-six
        hours advance actual notice of any termination pursuant to this Section
        7.1(c)(i) and shall have made the payment referred to in Section 7.3

              (ii) if prior to the purchase of Shares pursuant to the Offer,
        Parent or Sub (x) breaches or fails in any material respect to perform
        or comply with any of its material covenants and agreements contained
        herein or (y) breaches its representations and warranties in any
        material respect and such breach would
 
                                      A-30
<PAGE>
        have or would be reasonably likely to have a material adverse effect on
        Parent and its Subsidiaries; provided, however, that if any such breach
        is cured, the Company may not terminate this Agreement pursuant to this
        Section 7.1(c)(ii); or
 
             (iii) if Parent or Sub shall have terminated the Offer, or the
        Offer shall have expired, without Parent or Sub, as the case may be,
        purchasing any shares of Company Common Stock pursuant thereto; provided
        that the Company may not terminate this Agreement pursuant to this
        Section 7.1(c)(iii) if the Company is in material breach of this
        Agreement; or
 
              (iv) if, due to an occurrence that if occurring after the
        commencement of the Offer would result in a failure to satisfy any of
        the conditions set forth in Annex A hereto, Parent, Sub or any of their
        affiliates shall have failed to commence the Offer on or prior to five
        business days following the date of the initial public announcement of
        the Offer; provided, that the Company may not terminate this Agreement
        pursuant to this Section 7.1(c)(iv) if the Company is in material breach
        of this Agreement.
 
          (d) By the Board of Directors of Parent:
 
              (i) if, due to an occurrence that if occurring after the
        commencement of the Offer would result in a failure to satisfy any of
        the conditions set forth in Annex A hereto, Parent, Sub or any of their
        affiliates shall have failed to commence the Offer on or prior to five
        business days following the date of the initial public announcement of
        the Offer; provided that Parent may not terminate this Agreement
        pursuant to this Section 7.1(d)(i) if Parent or Sub is in material
        breach of this Agreement; or
 
              (ii) if (A) prior to the purchase of Shares pursuant to the Offer,
        the Board of Directors of the Company shall have withdrawn, or modified
        or changed in a manner adverse to Parent or Sub its approval or
        recommendation of the Offer, this Agreement or Merger or shall have

        recommended a Takeover Proposal or other business combination, or the
        Company shall have entered into an agreement in principle (or similar
        agreement) or definitive agreement providing for a Takeover Proposal or
        other business combination with a person or entity other than Parent,

        resolves to do any of the foregoing), or (B) prior to the consummation
        of the Offer, it shall have been publicly disclosed or Parent or Sub
        shall have learned that any person, entity or 'group' (as that term is
        defined in Section 13(d)(3) of the Exchange Act) (an 'Acquiring

        otherwise, to acquire beneficial ownership of more than 14.9% of any
        class or series of capital stock of the Company (including the Shares);
        or
 
             (iii) if Parent or Sub, as the case may be, shall have terminated
        the Offer, or the Offer shall have expired without Parent or Sub, as the
        case may be, purchasing any Shares thereunder, provided that Parent may
        not terminate this Agreement pursuant to this Section 7.1(d)(iii) if
        Parent or Sub is in material breach of this Agreement.
 
     Section 7.2 Effect of Termination.  In the event of the termination of this

     Shares), through the acquisition of stock, the formation of a group or

     otherwise, or shall have been granted an option, right or warrant,

     The foregoing conditions are for the sole benefit of Parent and Sub and may
be asserted by Parent or Sub regardless of the circumstances giving rise to any
such condition or may be waived by Parent or Sub in whole or in part at any time

and other circumstances shall not be deemed a waiver with respect to other facts
and circumstances; and each such right shall be deemed an ongoing right which
may be asserted at any time and from time to time.

                                                               November 29, 1995
 
Board of Directors
Rite Aid Corporation
30 Hunter Lane
Camp Hill, PA 17011
 
Dear Sirs:
 
     You have requested our opinion as to the fairness from a financial point of
view to the stockholders of Rite Aid Corporation (the 'Company') of the
consideration to be paid by the Company pursuant to the terms of the Agreement
and Plan of Merger to be dated as of November 29, 1995, among the Company, Ocean
Acquisition Corporation, a wholly owned subsidiary of the Company ('Acquisition
Sub') and Revco D.S., Inc. ('Revco') (the 'Agreement').
 
     Pursuant to the Agreement, the Company will commence a tender offer for not
less then 50.1% of the outstanding shares of the common stock of Revco at a
price of $27.50 per share. In its sole discretion, the Company may seek to
purchase up to all of such outstanding shares of Revco common stock pursuant to
such tender offer. The tender offer is to be followed by a merger in which all
shares of such Revco common stock not purchased in the offer would be converted
into shares of the Company's common stock pursuant to the conversion formulas
set forth in the Agreement. Under certain circumstances, the Company may elect,
in its sole discretion, to cause a portion of the merger consideration to be
paid in cash, as more fully provided in the Agreement. In addition, the
Agreement also requires that the Company make available the aggregate merger
consideration in a combination of cash and Company common stock if the Company's
stockholders shall not have approved the issuance of Company common stock in the
merger as contemplated by the Agreement.
 
     In arriving at our opinion, we have reviewed the Agreement, the associated
Stockholder Agreement between the Company and Zell/Chilmark Fund, L.P. and the
associated Stock Option Agreement between the Company and Revco, as well as
financial and other information that was publicly available or furnished to us
by the Company and Revco including information provided during discussions with
their respective managements. Included in the information provided during
discussions with the respective managements were certain financial projections
of Revco for the period beginning June 1996 and ending June 1998 prepared by the
management of Revco and certain financial projections of the Company for the
period beginning February 1996 and ending February 1998 prepared by the
management of the Company. In addition, we have compared certain financial and
securities data of the Company and Revco with various other companies whose
securities are traded in public markets, reviewed the historical stock prices
and trading volumes of the common stock of the Company and Revco, reviewed
prices and premiums paid in other business combinations and conducted such other
financial studies, analyses and investigations as we deemed appropriate for
purposes of this opinion.
 

     In rendering our opinion, we have relied upon and assumed the accuracy,
completeness and fairness of all of the financial and other information that was
available to us from public sources, that was provided to us by the Company and
Revco or their respective representatives, or that was otherwise reviewed by us.
In particular, we have relied upon the estimates of the management of the
Company of the operating synergies achievable as a result of the Merger and upon
our discussion of such synergies with the management of Revco. With respect to
the financial projections supplied to us, we have assumed that they have been
reasonably prepared on the basis reflecting the best currently available
estimates and judgments of the management of the Company and Revco as to the
future operating and financial performance of the Company and Revco. We have not
assumed any
 
                                      B-1
<PAGE>
responsibility for making any independent evaluation of Revco's assets or
liabilities or for making any independent verification of any of the information
reviewed by us.
 
     Our opinion is necessarily based on economic, market, financial and other
conditions as they exist on, and on the information made available to us as of,
the date of this letter. It should be understood that, although subsequent
developments may affect this opinion, we do not have any obligation to update,
revise or reaffirm this opinion. We are expressing no opinion herein as to the
prices at which the Company's common stock will trade at any time. Our opinion
does not constitute a recommendation to any stockholder of the Company or Revco
as to how such stockholder should vote on the proposed transaction.
 
     Donaldson, Lufkin & Jenrette Securities Corporation ('DLJ'), as part of its
investment banking services, is regularly engaged in the valuation of businesses
and securities in connection with mergers, acquisitions, underwritings, sales
and distributions of listed and unlisted securities, private placements and
valuations for estate, corporate and other purposes. DLJ has performed
investment banking and other services for both the Company and Revco in the past
and has been compensated for such services. Over the past two years, DLJ has (i)
lead managed a $200 million senior notes offering for the Company, (ii) advised
the Company in the sale of four of its non-drugstore subsidiaries and (iii)
advised the Company on its Dutch auction to buy back outstanding shares. DLJ has
received customary compensation for the above-mentioned services. Over the past
two years, DLJ has also (i) advised Revco on its acquisition of Hook-SupeRx and
provided $150 million of bridge financing for the acquisition and (ii) advised
Revco on its sale of certain stores acquired from Brooks Drug. DLJ has also
received customary compensation for the above-mentioned services.
 
     Based upon the foregoing and such other factors as we deem relevant, we are
of the opinion that the consideration to be paid by the Company pursuant to the
Agreement, taken as a whole, is fair to the stockholders of the Company from a
financial point of view.
 
                                          Very truly yours,

Board of Directors
Revco D.S., Inc.
1925 Enterprise Parkway
Twinsburg, OH 44087
 
Gentlemen and Madame:
 
     We understand that Revco D.S., Inc., a Delaware Corporation, (the
'Company'), Rite Aid Corporation, a Delaware Corporation, (the 'Buyer') and
Ocean Acquisition Corp., a Delaware Corporation and a wholly owned subsidiary of
Buyer ('Acquisition Sub'), have entered into an Agreement and Plan of Merger,
dated as of November 29, 1995 (the 'Merger Agreement'), which provides, among
other things, for (I) the commencement by Acquisition Sub of a cash tender offer
(the 'Offer') for not less than 50.1% (the 'Minimum Condition') of the issued
and outstanding shares of common stock, par value $.01 per share, of the Company
(the 'Company Common Stock') for $27.50 per share net to the seller in cash (in
the aggregate, the 'Offer Consideration'), and (II) upon satisfaction of the
Minimum Condition pursuant to the Offer, the subsequent merger (the 'Merger') of
Acquisition Sub with and into the Company. Pursuant to the Merger, the Company
will become a wholly owned subsidiary of the Buyer and each share of Company
Common Stock issued and outstanding immediately prior to the closing of the
Merger, other than shares held in treasury or held by Buyer or any subsidiary of
Buyer or as to which dissenters' rights have been perfected, shall be converted
into either (i) a number of shares of common stock, par value $1.00 per share,
of the Buyer (the 'Buyer Common Stock') to be determined based upon a formula
set forth in the Merger Agreement, subject to a collar which provides that the
exchange ratio shall not be greater than 1.12500 nor less than 0.91666 shares of
Buyer Common Stock per share of Company Common Stock (the 'Exchange Ratio'), or
(ii) in the event that the stockholders of Buyer do not approve the issuance of
Buyer Common Stock, a combination of Buyer Common Stock and cash based upon a
formula set forth in the Merger Agreement, whereby the number of shares of Buyer
Common Stock to be issued in the Merger will not exceed 19.9% of the Buyer
Common Stock outstanding immediately prior to the Merger (the shares of Buyer
Common Stock and/or cash to be received in the Merger being, in the aggregate,
the 'Merger Consideration' and together with the Offer Consideration, the
'Consideration'). We also understand that Parent and a holder of Company Common
Stock have entered into a Stockholder Agreement, dated as of November 29, 1995
(the 'Stockholder Agreement'), pursuant to which, among other things, such
holder has agreed to vote its shares in favor of the Merger. We further

understand that the Company and the Buyer have entered into a Stock Option
Agreement pursuant to which the Company has granted Buyer the right to purchase,
in certain circumstances, a number of shares of Company Common Stock equal to
19.9% of the shares of Company Common Stock outstanding at the time of exercise
of such purchase right. The terms and conditions of the Offer and the Merger are
more fully set forth in the Merger Agreement.
 
     You have asked for our opinion as to whether the Consideration to be
received by the holders of shares of Company Common Stock pursuant to the Offer
and the Merger, taken together, is fair from a financial point of view to such
holders.

     For purposes of the opinion set forth herein, we have:
 
            (i) analyzed certain publicly available financial statements and
     other information of the Company and the Buyer, respectively;
 
           (ii) reviewed certain internal financial statements and other
     financial and operating data concerning the Company and the Buyer prepared
     by the managements of the Company and the Buyer, respectively;
 
           (iii) reviewed certain financial projections for the Company and the
     Buyer, including estimates of certain potential benefits of the proposed
     business combination, prepared by the managements of the Company and the
     Buyer, respectively;
 
           (iv) discussed the past and current operations and financial
     condition and the prospects of the Company and the Buyer with senior
     executives of the Company and the Buyer, respectively;
 
            (v) reviewed the reported prices and trading activity for the
     Company Common Stock and the Buyer Common Stock;
 
           (vi) compared the financial performance of the Company and the Buyer
     and the prices and trading activity of the Company Common Stock and the
     Buyer Common Stock with that of certain other comparable publicly-traded
     companies and their securities;
 
           (vii) reviewed the financial terms, to the extent publicly available,
     of certain comparable acquisition transactions;
 
          (viii) participated in discussions among representatives of the
     Company and Parent and their legal advisors;
 
           (ix) reviewed the Merger Agreement, Stock Option Agreement and the
     Stockholder Agreement; and
 
            (x) performed such other analyses as we have deemed appropriate.
 
     We have assumed and relied without independent verification upon the
accuracy and completeness of the information reviewed by us for the purposes of
this opinion. With respect to the financial projections, including the estimates

of the Buyer and the Company of certain potential benefits of the proposed
business combination, we have assumed that they have been reasonably prepared on
bases reflecting the best currently available estimates and judgments of the
future financial performance of the Company and the Buyer, respectively. We have
not made any independent valuation or appraisal of the assets or liabilities of
the Company or the Buyer, nor have we been furnished with any such appraisals.
Our opinion is necessarily based on economic, market and other conditions as in
effect on, and the information made available to us as of, the date hereof. In
addition, for purposes of this opinion we have assumed that following completion
of the Offer the Merger will be consummated in accordance with the terms of the
Merger Agreement.
 
     In arriving at our opinion, we were not authorized to solicit, and did not
solicit, interest from any party with respect to the acquisition of the Company
or any of its assets.
 
     We express no opinion and make no recommendations as to whether the holders
of Company Common Stock should elect to tender their shares to the Acquisition
Sub pursuant to the Offer, nor do we express any recommendation as to how such
holders should vote at the stockholders' meeting held in connection with the
Merger.
 
     We have acted as financial advisor to the Board of Directors of the Company
in connection with this transaction and will receive a fee for our services. In
the past, Morgan Stanley & Co. Incorporated and its affiliates have provided
financial advisory and financing services to the Company and have received fees
for the rendering of these services.
 
     It is understood that this letter is for the information of the Board of
Directors of the Company and may not be used for any other purpose without our
prior written consent, except that this opinion may be included in its entirety
in any filing made by the Company or the Buyer with the Securities and Exchange
Commission with respect to the Offer and the Merger.

     Based on, and subject to, the foregoing, we are of the opinion on the date

     Stockholder shall give notice of such disclosure to Parent as promptly as
     practicable so as to enable Parent to seek a protective order from a court
     of competent jurisdiction with respect thereto.

        subsidiary of Parent, but no such assignment shall relieve Parent of its
        obligations hereunder if such assignee does not perform such

    or to such other address as the person to whom notice is given may have
    previously furnished to the others in writing in the manner set forth above.
 
             (f) Severability.  Whenever possible, each provision or portion of
        any provision of this Agreement will be interpreted in such manner as to
        be effective and valid under applicable law but if any provision or
        portion of any provision of this Agreement is held to be invalid,
        illegal or unenforceable in any respect under any applicable law or rule

        in any jurisdiction, such invalidity, illegality or unenforceability
        will not affect any other provision or portion of any provision in such
        jurisdiction, and this Agreement will be reformed, construed and
        enforced in such jurisdiction as if such invalid, illegal or
        unenforceable provision or portion of any provision had never been
        contained herein.
 
             (g) Specific Performance.  Each of the parties hereto recognizes
        and acknowledges that a breach by it of any covenants or agreements
        contained in this Agreement will cause the other party to sustain
        damages for which it would not have an adequate remedy at law for money
        damages, and therefore each of the parties hereto agrees that in the
        event of any such breach the aggrieved party shall be entitled to the
        remedy of specific performance of such covenants and agreements and
        injunctive and other equitable relief in addition to any other remedy to
        which it may be entitled, at law or in equity.
 
             (h) Remedies Cumulative.  All rights, powers and remedies provided
        under this Agreement or otherwise available in respect hereof at law or
        in equity shall be cumulative and not alternative, and the exercise of
        any thereof by any party shall not preclude the simultaneous or later
        exercise of any other such right, power or remedy by such party.
 
             (i) No Waiver.  The failure of any party hereto to exercise any
        right, power or remedy provided under this Agreement or otherwise
        available in respect hereof at law or in equity, or to insist upon
        compliance by any other party hereto with its obligations hereunder, and
        any custom or practice of the parties at variance with the terms hereof,
        shall not constitute a waiver by such party of its right to exercise any
        such or other right, power or remedy or to demand such compliance.
 
             (j) No Third Party Beneficiaries.  This Agreement is not intended
        to be for the benefit of, and shall not be enforceable by, any person or
        entity who or which is not a party hereto.
 
             (k) Governing Law.  This Agreement shall be governed and construed
        in accordance with the laws of the State of Delaware, without giving
        effect to the principles of conflicts of law thereof.
 
             (l) Jurisdiction.  Each party hereby irrevocably submits to the
        exclusive jurisdiction of the Court of Chancery in the State of Delaware
        in any action, suit or proceeding arising in connection with this
        Agreement, and agrees that any such action, suit or proceeding shall be
        brought only in such court (and waives any objection based on forum non
        conveniens or any other objection to venue therein); provided, however,
        that such consent to jurisdiction is solely for the purpose referred to
        in this paragraph (l) and shall not be deemed to be a general submission
        to the jurisdiction of said Court or in the State of Delaware other than
        for such purposes. Each party hereto hereby waives any right to a trial
        by jury in connection with any such action, suit or proceeding.
 
             (m) Descriptive Headings.  The descriptive headings used herein are
        inserted for convenience of reference only and are not intended to be
        part of or to affect the meaning or interpretation of this Agreement.

 
             (n) Counterparts.  This Agreement may be executed in counterparts,
        each of which shall be deemed to be an original, but all of which, taken
        together, shall constitute one and the same Agreement.

                             STOCK OPTION AGREEMENT
 
     AGREEMENT, dated as of November 29, 1995, by and among Rite Aid
Corporation, a Delaware corporation ('Parent'), Ocean Acquisition Corporation, a
Delaware corporation and a wholly owned subsidiary of Parent ('Sub'), and Revco
D.S., Inc., a Delaware corporation (the 'Company').
 
                              W I T N E S S E T H:
 
     WHEREAS, immediately prior to the execution of this Agreement, Parent, Sub
and the Company, have entered into an Agreement and Plan of Merger (as such
agreement may hereafter be amended from time to time, the 'Merger Agreement'),
pursuant to which Sub will be merged with and into the Company (the 'Merger');
 
     WHEREAS, in furtherance of the Merger, Parent and the Company desire that
as soon as practicable (but in no event later than five business days) after the
execution of the Merger Agreement, Sub shall commence an offer (the 'Offer') to
purchase for cash not less than 35,144,833 shares and up to all of the issued
and outstanding Company Common Stock (as defined in Section 1 hereof), or such
greater number of shares as equals 50.1% of the shares outstanding on a fully
diluted basis as of the expiration of the Offer, at a price of $27.50 per share
of Company Common Stock; and
 
     WHEREAS, as an inducement and a condition to entering into the Merger
Agreement, Parent and Sub have required that the Company agree, and the Company
has agreed, to enter into this Agreement;
 
     NOW, THEREFORE, in consideration of the foregoing and the mutual promises,
representations, warranties, covenants and agreements contained herein, the
parties hereto, intending to be legally bound hereby, agree as follows:
 
          1. Certain Definitions.  Capitalized terms used and not defined herein
     have the respective meanings ascribed to them in the Merger Agreement. For
     purposes of this Agreement:
 
             a. 'Beneficially Own' or 'Beneficial Ownership' with respect to any
        securities shall mean having 'beneficial ownership' of such securities
        (as determined pursuant to Rule 13d-3 under the Securities Exchange Act
        of 1934, as amended (the 'Exchange Act')), including pursuant to any
        agreement, arrangement or understanding, whether or not in writing.
        Without duplicative counting of the same securities by the same holder,
        securities Beneficially Owned by a Person shall include securities
        Beneficially Owned by all other Persons with whom such Person would
        constitute a 'group' within the meaning of Section 13(d) of the Exchange
        Act.
 
             b. 'Company Common Stock' shall mean at any time the common stock,
        $.01 par value, of the Company.
 
             c. 'Person' shall mean an individual, corporation, limited

        liability company, partnership, joint venture, association, trust,
        unincorporated organization or other entity.
 
          2. Grant of Stock Option.  In order to induce Parent and Sub to enter
     into the Merger Agreement, the Company hereby grants to Parent an
     unconditional, irrevocable option (a 'Stock Option') to purchase up to
     13,251,010 fully paid and nonassessable shares of Company Common Stock at a
     purchase price of $27.50 per share (the 'Purchase Price'), or such other
     number of shares of Company Common Stock as equals 19.9% of the Company's
     issued and outstanding shares of Company Common Stock at the time of
     exercise of the Stock Option; provided that in no event shall the number of
     shares of Company Common Stock for which the Stock Option is exercisable
     exceed 19.9% of the shares of Company Common Stock issued and outstanding
     at the time of exercise of the Stock Option (the 'Option Shares'). The
     number of shares of Company Common Stock that may be received upon the
     exercise of the Stock Option is subject to adjustments as herein set forth.
 
          3. Exercise of Stock Option.  (a) Upon (x) the occurrence of a Trigger
     Event (as defined in Section 7.3 of the Merger Agreement), or (y) the
     occurrence of the condition set forth in clause (h) of Annex A to the
     Merger Agreement, the Stock Option shall become immediately exercisable, in
     whole or in part, and remain
 
                                      E-1
<PAGE>
     exercisable in whole or in part until the later of (i) the date which is
     six months after the date the Stock Option first became exercisable and
     (ii) the fifth business day following expiration or termination of any
     applicable waiting period under the Hart-Scott-Rodino Antitrust
     Improvements Act of 1976, as amended (the 'HSR Act') (the 'Option Period').
 
             (b) In the event that Parent is entitled to and wishes to exercise
        the Stock Option, Parent shall, during the Option Period, send a written
        notice (the 'Notice') to the Company identifying the place and date for
        the closing of such purchase and the number of Option Shares to be
        purchased. Upon the giving by Parent to the Company of the Notice and
        the tender of the aggregate Purchase Price at the closing so specified,
        Parent shall be deemed to be the holder of record of the shares of
        Company Common Stock issuable upon such exercise, notwithstanding that
        the stock transfer books of the Company shall then be closed or that
        certificates representing such shares of Company Common Stock shall not
        then be actually delivered to Parent. The Company shall pay all
        expenses, and any and all United States federal, state and local taxes
        and other charges that may be payable in connection with the
        preparation, issue and delivery of stock certificates under this Section
        3 in the name of Parent or its assignee, transferee or designee.
 
          4. Sale of Option Shares.  If, at any time following the exercise of
     the Option, Parent shall either (i) transfer, sell or otherwise dispose of
     any or all of the Option Shares, including, without limitation, by means of
     tender or exchange of any or all of the Option Shares pursuant to a tender
     or exchange offer involving the capital stock of the Company, or (ii)
     convert such Option Shares into cash, capital stock, other securities or
     any other consideration of any third party in a merger any recapitalization

     or restructuring or similar business combination transaction (a 'Business
     Combination Transaction'), Parent shall pay to the Company within five days
     the amount equal to the Profit (as defined below) Parent shall receive, if
     any, pursuant to such Disposition or Business Combination Transaction.
     'Profit', for purposes of this Agreement, shall equal (i) the product of
     (a) the number of Option Shares Parent transfers, sells, tenders, exchanges
     or otherwise disposes of pursuant to a Disposition or a Business
     Combination Transaction by (b) the excess of the per Share consideration
     received by Parent pursuant to such Disposition or Business Combination
     Transaction valuing any non-cash consideration at its fair market value on
     the date of such consummation (not including any increase in such aggregate
     per Share consideration after the date thereof) over the Purchase Price.
     For purposes hereof, the fair market value of any non-cash consideration
     shall be the closing price or the last sale price, or, in case no such sale
     takes place on the day of consummation of such Business Combination
     Transaction, the average of the closing bid and asked prices, in either
     case as reported in the principal consolidated transaction reporting system
     with respect to securities listed or admitted to trading on the principal
     national securities exchange on which such consideration is listed or
     admitted to trading or, if such consideration is not listed or admitted to
     trading on any national securities exchange, the last quoted price or, if
     not so quoted, the average of the high bid and low asked prices in the
     over-the-counter market, as reported by the National Association of
     Securities Dealers, Inc. Automated Quotation System or such other system
     then in use, or, if not so determinable, the fair value of such
     consideration on such date shall be determined in good faith by the Board
     of Directors of Parent.
 
          5. Covenants, Representations and Warranties of the Company.  The
     Company hereby represents and warrants to, and agrees with, Parent and Sub
     as follows:

        Parent or Sub are necessary to authorize the execution, delivery or
        performance of this Agreement or the consummation of the transactions
        contemplated hereby.
 
             b. Corporate Authorization.  This Agreement has been duly and
        validly executed and delivered by Parent and Sub and constitutes a valid
        and binding agreement of each of Parent and Sub enforceable against each
        of Parent and Sub in accordance with its terms, except that (i) such
        enforcement may be subject to applicable bankruptcy, insolvency or other
        similar laws, now or hereafter in effect, affecting creditors' rights
        generally, and (ii) the remedy of specific performance and injunctive
        and other forms of equitable relief may be subject to equitable defenses
        and to the discretion of the court before which any proceeding therefor
        may be brought.
 
             c. No Conflicts.  Except for filings, authorizations, consents and
        approvals as may be required under the HSR Act, the Exchange Act and the
        Securities Act (i) no filing with, and no permit, authorization, consent
        or approval of, any state or federal public body or authority is
        necessary for the execution of this Agreement by Parent or Sub and the
        consummation by Parent or Sub of the transactions contemplated hereby
        and (ii) none of the execution and delivery of this Agreement by Parent
        of Sub, the consummation by Parent or Sub of the transactions
        contemplated hereby or compliance by Parent or Sub with any of the
        provisions hereof shall (A) conflict with or result in any breach of any
        applicable organizational documents applicable to Parent or Sub, (B)
        result in a violation or breach of, or constitute (with or without

        notice or lapse of time or both) a default (or give rise to any third
        party right of termination, cancellation, material modification or
        acceleration) under any of the terms, conditions or provisions of any
        note, loan agreement, bond, mortgage, indenture, license, contract,
        commitment, arrangement, understanding, agreement or other instrument or
        obligation of any kind to which Parent or Sub is a party or by which
        Parent or Sub or any of their respective properties or assets may be
        bound, or (C) violate any order, writ, injunction, decree, judgment,
        statute, rule or regulation applicable to Parent or Sub or any of their
        respective properties or assets.
 
          7. Adjustment Upon Changes in Capitalization.  In the event of any
     change in Company Common Stock by reason of stock dividends, split-ups,
     recapitalizations, combinations, exchanges of shares or the like, the type
     and number of shares of Company Common Stock subject to the Stock Option
     and the Purchase Price shall be appropriately adjusted and proper provision
     shall be made so that, in the event that any additional shares of Company
     Common Stock are issued or otherwise become outstanding as a result of any
     such change after the date of this Agreement (other than pursuant to this
     Agreement), the number of shares of Company Common Stock subject to the
     Stock Option shall be adjusted so that, after such issuance and together
     with shares of Company Common Stock previously issued pursuant to the
     exercise of the Stock Option (as adjusted on account of any of the
     foregoing change in Company Common Stock), it equals 19.9% of the number of
     shares of Company Common Stock then issued and outstanding. Nothing
     contained in this Section 7 shall be deemed to authorize the Company to
     breach any provision of the Merger Agreement.
 
          8. Registration Rights.  The Company shall, if requested by Parent at
     any time and from time to time within three years of the first exercise of
     the Stock Option, promptly prepare, file and keep current a registration
     statement under the Securities Act in order to permit the sale or other
     disposition of the shares of Company Common Stock that have been acquired
     by or are issuable to Parent upon exercise of the Stock Option in
     accordance with the intended method of sale or other disposition stated by
     Parent, including a 'shelf' registration statement under Rule 415 of the
     Securities Act or any successor provision, and the Company shall use its
     best efforts to qualify such shares or other securities under any
     applicable state securities laws. Parent shall provide all information
     reasonably requested by the Company for inclusion in any registration
     statement to be filed hereunder. The Company will use its best efforts to
     cause such registration statement first to become effective and then to
     remain effective for such period not in excess of 180 days from the day
     such registration statement first becomes effective or such shorter time as
     may be reasonably necessary to effect such sales or other dispositions.
     Parent shall have the right to demand one such registration. The Company
     shall bear the costs of such registration (including, but not limited to,
     the
 
                                      E-4
<PAGE>
     Company's attorneys' fees, printing costs and filing fees, except for
     underwriting discounts or commissions, brokers' fees and the fees and
     disbursements of Parent's counsel related thereto). If requested by Parent,

     in connection with such registration, the Company will become a party to
     any underwriting agreement relating to the sale of such shares, but only to
     the extent of obligating itself in respect of representations, warranties,
     indemnities, and other agreements customarily included in such underwriting
     agreements. Upon receiving any request from the Company or assignee thereof
     under this Section 8, the Company agrees to send a copy thereof to Parent
     and to any assignee thereof known to the Company, in each case by promptly
     mailing the same, postage prepaid, to the address of record of the person
     entitled to receive such copies.
 
          9. Termination.  Except as otherwise provided herein, the covenants
     and agreements contained herein with respect to the Option Shares shall
     terminate upon the earlier of (i) the consummation of the Merger and (ii)
     the expiration of the Option Period.
 
          10. Miscellaneous.
 
             a. Entire Agreement.  Except as otherwise expressly provided
        herein, this Agreement contains the entire agreement between the parties
        with respect to the transactions contemplated hereunder and supersedes
        all prior arrangements or understandings with respect thereto, written
        or oral. The terms and conditions of this Agreement shall inure to the
        benefit of and be binding upon the parties hereto and their respective
        successors and assigns. Nothing in this Agreement, expressed or implied,
        is intended to confer upon any party, other than the parties hereto, and
        their respective successors and assigns, any rights, remedies,
        obligations or liabilities under or by reason of this Agreement, except
        as expressly provided herein.
 
             b. Assignment.  This Agreement shall not be assigned by operation
        of law or otherwise without the prior written consent of the other
        party, provided that Parent may assign, in its sole discretion, its
        rights and obligations hereunder to any direct or indirect wholly owned
        subsidiary of Parent, but no such assignment shall relieve Parent of its
        obligations hereunder if such assignee does not perform such
        obligations.
 
             c. Amendments, Waivers, Etc.  This Agreement may not be amended,
        changed, supplemented, waived or otherwise modified or terminated,
        except upon the execution and delivery of a written agreement executed
        by the parties hereto.
 
             d. Notices.  All notices, requests, claims, demands and other
        communications hereunder shall be in writing and shall be given (and
        shall be deemed to have been duly received if given) by hand delivery or
        telecopy (with a confirmation copy sent for next day delivery via
        courier service, such as Federal Express), or by any courier service,
        such as Federal Express, providing proof of delivery. All communications
        hereunder shall be delivered to the respective parties at the following

    or to such other address as the person to whom notice is given may have
    previously furnished to the others in writing in the manner set forth above.
 
             e. Severability.  Whenever possible, each provision or portion of
        any provision of this Agreement will be interpreted in such manner as to
        be effective and valid under applicable law but if any provision or
        portion of any provision of this Agreement is held to be invalid,
        illegal or unenforceable in any respect under any applicable law or rule
        in any jurisdiction, such invalidity, illegality or unenforceability
        will not affect any other provision or portion of any provision in such
        jurisdiction, and this Agreement will be reformed, construed and
        enforced in such jurisdiction as if such invalid, illegal or
        unenforceable provision or portion of any provision had never been
        contained herein.
 
             f. Specific Performance.  Each of the parties hereto recognizes and
        acknowledges that a breach by it of any covenants or agreements
        contained in this Agreement will cause the other party to sustain

        damages for which it would not have an adequate remedy at law for money
        damages, and therefore each of the parties hereto agrees that in the
        event of any such breach the aggrieved party shall be entitled to the
        remedy of specific performance of such covenants and agreements and
        injunctive and other equitable relief in addition to any other remedy to
        which it may be entitled, at law or in equity.
 
             g. Remedies Cumulative.  All rights, powers and remedies provided
        under this Agreement or otherwise available in respect hereof at law or
        in equity shall be cumulative and not alternative, and the exercise of
        any thereof by any party shall not preclude the simultaneous or later
        exercise of any other such right, power or remedy by such party.
 
             h. No Waiver.  The failure of any party hereto to exercise any
        right, power or remedy provided under this Agreement or otherwise
        available in respect hereof at law or in equity, or to insist upon
        compliance by any other party hereto with its obligations hereunder, and
        any custom or practice of the parties at variance with the terms hereof,
        shall not constitute a waiver by such party of its right to exercise any
        such or other right, power or remedy or to demand such compliance.
 
             i. No Third Party Beneficiaries.  This Agreement is not intended to
        be for the benefit of, and shall not be enforceable by, any person or
        entity who or which is not a party hereto.
 
             j. Governing Law.  This Agreement shall be governed and construed
        in accordance with the laws of the State of Delaware, without giving
        effect to the principles of conflicts of law thereof.
 
             k. Jurisdiction.  Each party hereby irrevocably submits to the
        exclusive jurisdiction of the Court of Chancery in the State of Delaware
        in any action, suit or proceeding arising in connection with this
        Agreement, and agrees that any such action, suit or proceeding shall be
        brought only in such court (and waives any objection based on forum non
        conveniens or any other objection to venue therein); provided, however,
        that such consent to jurisdiction is solely for the purpose referred to
        in this paragraph (l) and shall not be deemed to be a general submission
        to the jurisdiction of said Court or in the State of Delaware other than
        for such purposes. Each party hereto hereby waives any right to a trial
        by jury in connection with any such action, suit or proceeding.

             m. Counterparts.  This Agreement may be executed in counterparts,
        each of which shall be deemed to be an original, but all of which, taken
        together, shall constitute one and the same Agreement.
 
     IN WITNESS WHEREOF, Parent, Sub and the Company have caused this Agreement
to be duly executed as of the day and year first above written.
