Dear Stockholder:
   
  You are cordially invited to attend the Special Meeting of Stockholders of
Rite Aid Corporation to be held at the Holiday Inn Harrisburg East, 4751
Lindle Road, Harrisburg, Pennsylvania, on Thursday, December 12, 1996, at 9:30
a.m., Eastern Time.     
   
  At the Rite Aid Special Meeting, stockholders will be asked to adopt the
Agreement and Plan of Merger between Rite Aid and Thrifty PayLess Holdings,
Inc., as amended (the "Merger Agreement"), and the issuance of Rite Aid Common
Stock to Thrifty PayLess stockholders pursuant thereto. The Merger Agreement
provides for the merger of Thrifty PayLess with and into Rite Aid. In the
Merger, Thrifty PayLess Common Stock will be converted into Rite Aid Common
Stock based on an exchange ratio of 0.65 shares of Rite Aid Common Stock for
each share of Thrifty PayLess Common Stock. In addition, pursuant to the
Merger Agreement, Rite Aid's Certificate of Incorporation will be amended in
order, among other things, to increase the number of shares of authorized Rite
Aid Common Stock from 240 million to 300 million.     
 
  The Merger, the Merger Agreement and the terms and conditions thereof are
more fully described in the accompanying Joint Proxy Statement/Prospectus. We
urge you to review this material carefully.
 
  Rite Aid's Board of Directors has unanimously determined that the Merger and
the transactions contemplated by the Merger Agreement are fair to and in the
best interests of the stockholders of Rite Aid, has approved the Merger
Agreement and recommends that Rite Aid stockholders vote "for" adoption of the
Merger Agreement.
 
  The acquisition of Thrifty PayLess is an integral part of Rite Aid's
strategy to operate drug stores in large, fast-growing metropolitan areas.
During fiscal 1998, we plan to close the Thrifty PayLess headquarters in
Wilsonville, Oregon. This closing combined with increased purchasing
efficiencies should enhance Rite Aid's earnings for the year. In addition,
Rite Aid intends to rapidly install its proprietary technology into all
Thrifty PayLess stores. Over the next three years, we anticipate that the
results at the Thrifty PayLess stores will more closely mirror the Rite Aid
stores. The combined company will operate over 3,500 stores and have revenues
greater than $10 billion. Our emphasis on technology and marketing are
designed to position us as an attractive provider to managed care
organizations.
 
  It is important that your shares of Rite Aid Common Stock are represented at
the Special Meeting, regardless of the number of shares you hold. Whether or
not you plan to attend the Special Meeting, please sign, date and return your
proxy card in the enclosed postage paid envelope as soon as possible. If you
later decide to attend the Special Meeting and vote in person, or if you wish
to revoke your proxy for any reason prior to the vote at the Special Meeting,
you may do so and your proxy will have no further effect. If you attend the
Special Meeting, you may vote in person, if you wish, even though you
previously mailed your proxy.
   
  As previously announced, Rite Aid is redeeming the so-called poison pill
rights previously declared in respect of Rite Aid Common Stock. Accordingly, a
check in payment of the redemption price ($0.01 per share of Common Stock
owned of record as of November 12, 1996) will be mailed under separate cover.
Rite Aid has been advised by its legal counsel that such amounts will be
treated as dividend income for federal income tax purposes.     
 
                                          Sincerely,
 
                                          /s/ Martin L. Grass

                           NOVEMBER 12, 1996     
 
Dear Stockholder:
   
  You are cordially invited to attend the Special Meeting of Stockholders of
Thrifty PayLess Holdings, Inc. to be held at The Sheraton Grande Hotel, Caucus
Room, 333 South Figueroa Street, Los Angeles, California on December 12, 1996
at 9:00 a.m., Pacific Standard Time.     
   
  The purpose of the Thrifty PayLess Special Meeting is to consider a proposal
to approve and adopt an Agreement and Plan of Merger, dated as of October 13,
1996, as amended, between Thrifty PayLess and Rite Aid Corporation. The Merger
Agreement provides for Thrifty PayLess' acquisition by Rite Aid through the
merger of Thrifty PayLess into Rite Aid, with Rite Aid surviving the merger,
and related transactions.     
 
  Pursuant to the merger, each share of Class A Common Stock and Class B
Common Stock of Thrifty PayLess (other than shares owned by Thrifty PayLess as
treasury stock, shares held by Rite Aid or any wholly owned subsidiary of Rite
Aid or Thrifty PayLess, and shares of Class A Common Stock as to which
appraisal rights have been properly exercised and perfected) will, by virtue
of the merger and without any action on the part of the holder thereof, be
converted into the right to receive 0.65 shares of duly authorized, validly
issued, fully paid and nonassessable Common Stock of Rite Aid (the "Exchange
Ratio"), which shares will be listed on the New York Stock Exchange. In
addition, upon consummation of the merger, each outstanding option or warrant
to purchase shares of Thrifty PayLess Common Stock will be accelerated and
converted automatically into a right to receive an amount of cash equal to (i)
65% of the closing sales price per share of Rite Aid Common Stock on the New
York Stock Exchange as reported on the New York Stock Exchange Composite Tape
for the date on which the merger becomes effective, minus the exercise price
per share under the applicable option or warrant, times (ii) the number of
shares of Thrifty PayLess Common Stock purchasable upon exercise of such
option or warrant. The obligation of Thrifty PayLess to consummate the merger
is subject, at Thrifty PayLess' option, to a minimum price condition with
respect to the Rite Aid Common Stock and certain other conditions, as
described more fully in the enclosed Joint Proxy Statement/Prospectus.
 
  Your Board of Directors, by unanimous vote, approved the Merger Agreement
and the transactions contemplated thereby (including the merger) as being in
the best interests of Thrifty PayLess and its stockholders. ACCORDINGLY, YOUR
BOARD OF DIRECTORS RECOMMENDS THAT YOU VOTE "FOR" ADOPTION OF THE MERGER
AGREEMENT AND THE TRANSACTIONS CONTEMPLATED THEREBY (INCLUDING THE MERGER).
Our recommendation and our reasons for it, as well as the background of the
transaction, certain risks associated therewith, required regulatory approvals
and other conditions to closing and other important information regarding the
transaction are set forth in the accompanying Joint Proxy
Statement/Prospectus.
 
  Rite Aid has entered into a Stockholder Agreement with each of Thrifty
PayLess' two largest stockholders, Green Equity Investors, L.P. and Kmart
Corporation, pursuant to which such stockholders have each agreed, among other
things, to vote all shares of Thrifty PayLess Common Stock owned by each of
them in favor of adoption of the Merger Agreement and the transactions
contemplated thereby. As of the date of this letter, such stockholders own an
aggregate of 24,998,513 shares, or approximately 42%, of outstanding Thrifty
PayLess Common Stock.
 
  Your vote is important, regardless of the number of shares you own. Adoption
of the Merger Agreement and the transactions contemplated thereby requires the
affirmative vote of the holders of a majority of the outstanding shares of
Thrifty PayLess Class A Common Stock and Class B Common Stock, voting together
as a single class. Accordingly, whether or not you plan to attend the Thrifty
PayLess Special Meeting, you are urged 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 Thrifty PayLess Special
Meeting or voting in person, but will assure that your vote is counted if you
are unable to attend such 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 Thrifty PayLess at Thrifty
PayLess' principal executive offices prior to the Thrifty PayLess Special
Meeting or by attending the Thrifty PayLess Special Meeting and voting in
person.
 
                                      Sincerely,
 
                                      /s/ Leonard I. Green

CERTAIN FILINGS AND OTHER INFORMATION
   
  Each of Rite Aid and Thrifty PayLess is subject to the information and
reporting requirements of the Securities Exchange Act of 1934, as amended (the
"Exchange Act"), and in accordance therewith files periodic reports, proxy
statements and other information with the Securities and Exchange Commission
(the "Commission"). Such reports, proxy statements and other information may
be inspected and copied at the public reference facilities maintained by the
Commission at 450 Fifth Street, N.W., Room 1024, Washington, D.C. 20549; 7
World Trade Center, Suite 1300, New York, New York 10048; and Citicorp Center,
500 West Madison Street, Suite 1400, Chicago, Illinois 60661. Copies of such
reports, proxy statements and other information also can be obtained by mail
from the Public Reference Section of the Commission, 450 Fifth Street, N.W.,
Washington, D.C. 20549, at prescribed rates. Such reports, proxy statements
and other information relating to Rite Aid and Thrifty PayLess also may be
inspected at the offices of the NYSE at 20 Broad Street, New York, New York
10005 and, in the case of Rite Aid, from the PSE, 301 Pine Street, San
Francisco, California 94104. The Commission maintains a Web site that contains
reports, proxy statements and other information filed electronically by Rite
Aid and Thrifty PayLess with the Commission which can be accessed over the
Internet at http://www.sec.gov.     
   
  Rite Aid has filed with the Commission a registration statement on Form S-4
(together with all amendments, supplements and exhibits thereto, the
"Registration Statement") under the Securities Act with respect to the Rite
Aid Common Stock to be issued pursuant to the Merger Agreement. As permitted
under the Securities Act and the Exchange Act, this Joint Proxy
Statement/Prospectus does not contain all the information set forth in the
Registration Statement. Such additional information can be inspected and
copied or obtained from the Commission in the manner described above.
Statements contained in this Joint Proxy Statement/Prospectus, or in any
document incorporated in this Joint Proxy Statement/Prospectus by reference,
as to the contents of any other document referred to herein or therein are not
necessarily complete, and each such statement is qualified in all respects by
reference to the copy of such other document filed as an exhibit to the
Registration Statement or such other document.     
 
CERTAIN FORWARD-LOOKING STATEMENTS AND MERGER CONSIDERATIONS
   
  This Joint Proxy Statement/Prospectus (including the documents incorporated
by reference herein) contains certain forward-looking statements (as such term
is defined in the Private Securities Litigation Reform Act of 1995) and
information relating to Rite Aid and Thrifty PayLess that are based on the
beliefs of the management of Rite Aid or Thrifty PayLess, as applicable, as
well as assumptions made by and information currently available to the
managements of Rite Aid or Thrifty PayLess, as applicable. When used in this
Joint Proxy Statement/Prospectus, the words "anticipate," "believe,"
"estimate," "expect," "intend" and similar expressions, as they relate to Rite
Aid, Thrifty PayLess or the management of either of them, identify forward-
looking statements. Such statements, which include, without limitation, the
matters set forth herein under "The Merger--Certain Projected Financial
Information" and "Unaudited Pro Forma Condensed Consolidated Financial Data,"
reflect the current views of Rite Aid or Thrifty PayLess, as applicable, with
respect to future events, the outcome of which is subject to certain risks,
including among others (i) competition from other drug store chains,
supermarkets, membership clubs and other retailers as well as third party
plans and mail order providers, (ii) the continued efforts of third party
payors to reduce prescription drug costs, and (iii) possible federal and state
health care reform initiatives to reduce governmental health costs. In
addition, Thrifty PayLess' consolidated federal income tax returns for fiscal
years 1992 through 1994 are currently being audited by the Internal Revenue
Service (the "IRS"), which has challenged and/or raised issues with respect to
certain positions adopted by Thrifty PayLess (see the registration statement
of Thrifty PayLess referenced in the Form 8-K referred to in item 7 under
"Incorporation of Certain Documents by Reference"). The forward looking
statements referred to above are also subject to uncertainties and assumptions
relating to the operations and results of operations of Rite Aid following the
Merger, including Rite Aid's ability successfully to integrate the operations
of Rite Aid and Thrifty PayLess (particularly in light of the different
merchandising strategies and store sizes and the geographic separation of the
two chains) while continuing to manage the day-to-day business of the combined
company, pricing pressures, shifts in market demand and general economic
conditions, all of     
 
                                       1
<PAGE>
 
which are factors that may affect the timing and realization of cost savings
and other synergistic benefits of the Merger assumed by Rite Aid. See "The
Merger--Rite Aid's Reasons for the Merger; Recommendation of the Rite Aid
Board." Should one or more of these risks or uncertainties materialize, or
should underlying assumptions prove incorrect, actual results or outcomes may
vary materially from those described herein as anticipated, believed,
estimated, expected or intended. Stockholders of Rite Aid and Thrifty PayLess
are urged to consider the foregoing considerations in evaluating the
information contained herein.

  The following is a summary of certain information contained elsewhere in this
Joint Proxy Statement/Prospectus and does not purport to be complete. This
summary is qualified in its entirety by reference to the more detailed
information contained elsewhere in this Joint Proxy Statement/Prospectus, the
Annexes hereto and the documents referred to herein. Stockholders are urged to
review carefully this Joint Proxy Statement/Prospectus, the Merger Agreement
attached hereto as Annex A and the other Annexes attached hereto. Capitalized
terms used but not defined herein have the respective meanings assigned thereto
in the Merger Agreement.
 
THE COMPANIES
 
  Rite Aid. Rite Aid, incorporated in 1968, is one of the largest retail drug
store chains in the United States. As of August 31, 1996, Rite Aid operated
2,796 drug stores, averaging within a range of approximately 7,200 to 11,000
square feet per store in size, in 21 states and the District of Columbia and
employed over 36,000 employees. Pharmacy service forms the core of Rite Aid's
business, with prescriptions accounting for 56.4% of drug store sales in the 26
week period ended August 31, 1996. Rite Aid's drug stores cater to convenience,
offering a full selection of health and personal care products, seasonal
merchandise and a large private label product line. Express mail with
complementary services and one-hour photo departments have recently been added
in select locations. Rite Aid's Eagle managed care subsidiary markets
prescription plans and sells other managed health care services to large
employers and government-sponsored employee benefit programs. Rite Aid is a
Delaware corporation with its principal executive offices located at 30 Hunter
Lane, Camp Hill, Pennsylvania 17011. The telephone number of Rite Aid at such
offices is (717) 761-2633.
 
  Rite Aid's strategy is to operate drug stores in large, fast-growing
metropolitan areas. Following the Merger, and giving effect to the Southeast
Dispositions described below, Rite Aid will be the largest drug store operator
in the United States in terms of store count, operating in 26 states. Of the 50
largest metropolitan statistical areas in the United States, Rite Aid will
operate in 25 and will be the largest or second largest drug store operation in
21 of those metropolitan areas. In connection with the announcement of the
Merger Agreement, Rite Aid also announced that it plans to dispose of all of
its 270 stores in Alabama, Florida, Georgia and North and South Carolina
(collectively, the "Southeast Dispositions"), and that in connection therewith
Rite Aid entered into an agreement to sell its approximately 200 stores in
North and South Carolina to Thrift Drug, Inc.
 
  As soon as is reasonably practicable following the Merger, Rite Aid expects
to rename all Thrifty PayLess stores "Rite Aid" and integrate them with Rite
Aid's operations, to refinance substantially all of Thrifty PayLess' existing
debt (to the extent practicable), to close Thrifty PayLess' Wilsonville, Oregon
headquarters and to divest Thrifty PayLess' Bi-Mart membership discount stores.
Rite Aid expects the elimination of duplicative overhead expenses and the
combined company's enhanced purchasing efficiencies to result in annual cost
savings of at least $65.0 million. Rite Aid also believes that there are other
cost-saving opportunities presented by the Merger (including lowering Thrifty
PayLess' historical debt expense, distribution costs and inventory shrinkage
rate), as well as opportunities for enhanced revenue growth from the increased
scale of operations and geographic diversity which Rite Aid will have after the
Merger. In addition, the application of Rite Aid's systems and technology to
Thrifty PayLess' operations should result in greater efficiencies. Giving
effect to expected cost reductions resulting from the Merger, the Merger is
expected by Rite Aid to be accretive to its earnings in the fiscal year ended
February 28, 1998 and thereafter. See "The Merger--Rite Aid's Reasons for the
Merger; Recommendation of the Rite Aid Board."
 
  Thrifty PayLess. Thrifty PayLess (originally known as TCH Corporation) was
formed in 1992 by Green Equity Investors, L.P. ("GEI"), whose general partner
is Leonard Green & Associates, L.P. ("LGA"), when Thrifty PayLess acquired
Thrifty Corporation from Pacific Enterprises (the "1992 Thrifty Acquisition").
In April 1994, Thrifty PayLess acquired (the "1994 PayLess Acquisition") Pay
Less Drug Stores Northwest, Inc.
 
                                       3

("PayLess") from Kmart Corporation ("Kmart"). Thrifty PayLess is a holding
company that, through its subsidiaries Thrifty PayLess, Inc. ("TPI") and Bi-
Mart Corporation ("Bi-Mart"), operates Thrifty and PayLess drug stores and Bi-
Mart membership discount stores. Thrifty PayLess' principal executive offices
are located at 9275 S.W. Peyton Lane, Wilsonville, Oregon 97070, and its
telephone number is (503) 682-4100. Thrifty PayLess was incorporated in
Delaware in 1992.     
   
  Thrifty PayLess is the largest drug store chain in the western United States.
As of September 30, 1996, it operated over 1,000 drug stores located in
California, Oregon, Washington and eight other western states. Its stores
average approximately 17,500 square feet of selling space, and it has over
31,000 employees. Thrifty PayLess' primary focus is the sale of prescription
drugs, which represented approximately 32% of Thrifty PayLess' total sales in
its fiscal year ended October 1, 1995 (exclusive of Bi-Mart sales). Thrifty
PayLess drug stores also offer a wide variety of non-pharmacy merchandise,
including health and beauty aids, cosmetics, photofinishing, greeting cards,
school and office supplies, seasonal merchandise, general merchandise and
consumable products such as snack food, candy, ice cream and beverages,
including liquor where permitted. Through Bi-Mart, Thrifty PayLess also
presently operates a chain of 45 Bi-Mart membership discount stores. Bi-Mart
stores feature a wide variety of general merchandise in a "no-frills" shopping
format that enables Bi-Mart to provide its approximately 1.2 million members
with substantial discounts from suggested retail prices.     
 
RITE AID SPECIAL MEETING
   
  Purpose. The Rite Aid Special Meeting will be held at the Holiday Inn
Harrisburg East, 4751 Lindle Road, Harrisburg, Pennsylvania, on December 12,
1996 at 9:30 a.m., Eastern Time, to consider and vote upon a proposal to adopt
the Merger Agreement and the issuance of Rite Aid Common Stock to the holders
of Thrifty PayLess Common Stock pursuant thereto. Pursuant to the Merger
Agreement, among other things, (i) Thrifty PayLess will merge with and into
Rite Aid, with Rite Aid as the surviving corporation in the Merger, (ii)
subject to certain exceptions, each outstanding share of Thrifty PayLess Common
Stock will be converted into 0.65 of a share of Rite Aid Common Stock (the
"Exchange Ratio") and (iii) Rite Aid's Certificate of Incorporation will be
amended in order to increase the number of authorized shares of Rite Aid Common
Stock from 240 million to 300 million, simplify the purpose clause, remove
certain obsolete provisions and effect certain other minor technical
amendments. See "The Merger Agreement--General", "The Merger--Amendment of Rite
Aid Certificate of Incorporation" and "The Meetings--Rite Aid Special Meeting."
The stockholders of Rite Aid will also consider and take action upon any other
business which may be properly brought before the Rite Aid Special Meeting.
       
  Record Date. Only holders of record of Rite Aid Common Stock at the close of
business on November 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 83,928,120 shares of Rite Aid
Common Stock outstanding, each of which entitles the registered holder thereof
to one vote. See "The Meetings--Record Date; Voting Rights."     
 
  Required Vote. Adoption of the Merger Agreement will require the affirmative
vote of a majority of the shares of Rite Aid Common Stock outstanding as of the
Rite Aid Record Date. See "The Meetings--Required Vote."
 
  THE BOARD OF DIRECTORS OF RITE AID (THE "RITE AID BOARD") HAS UNANIMOUSLY
APPROVED THE MERGER AGREEMENT AND UNANIMOUSLY RECOMMENDS THAT RITE AID
STOCKHOLDERS VOTE "FOR" ADOPTION OF THE MERGER AGREEMENT. SEE "THE MERGER--RITE
AID'S REASONS FOR THE MERGER; RECOMMENDATION OF THE RITE AID BOARD."
   
  Share Ownership of Directors and Officers. 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
4,814,062 (approximately 5.7%) of the shares of Rite Aid Common Stock then
outstanding. See "The Meetings--Share Ownership of Officers, Directors and
Certain Stockholders."

entitled to receive notice of and to vote at the Thrifty PayLess Special
Meeting. At the close of business on the Thrifty PayLess Record Date, there
were 59,501,807 shares of Thrifty PayLess Common Stock outstanding (consisting
of 16,804,002 shares of A Common Stock and 42,697,805 shares of B Common
Stock), each of which entitles the registered holder thereof to one vote as to
the adoption of the Merger Agreement. See "The Meetings--Record Date; Voting
Rights."     
 
  Required Vote. Adoption of the Merger will require the affirmative vote of a
majority of the shares of A Common Stock and B Common Stock outstanding as of
the Thrifty PayLess Record Date entitled to vote thereon, voting together as a
single class. See "The Meetings--Required Vote."
 
  THE BOARD OF DIRECTORS OF THRIFTY PAYLESS (THE "THRIFTY PAYLESS BOARD") HAS
UNANIMOUSLY APPROVED THE MERGER AGREEMENT AND UNANIMOUSLY RECOMMENDS THAT
THRIFTY PAYLESS STOCKHOLDERS VOTE "FOR" ADOPTION OF THE MERGER AGREEMENT. SEE
"THE MERGER--THRIFTY PAYLESS' REASONS FOR THE MERGER; RECOMMENDATION OF THE
THRIFTY PAYLESS BOARD."
   
  Share Ownership of Officers, Directors and Certain Stockholders. At the close
of business on the Thrifty PayLess Record Date, directors and executive
officers of Thrifty PayLess and their affiliates were the beneficial owners of
an aggregate of approximately 14,748,894 (approximately 24.8%) of the shares of
Thrifty PayLess Common Stock then outstanding (which amount includes the
14,376,264 shares owned by GEI, as to which Leonard I. Green, Jonathan D.
Sokoloff and Jennifer Holden Dunbar, each a director of Thrifty PayLess, may be
considered a beneficial owner because they (or entities controlled by them) are
general partners of LGP, which is GEI's general partner). As of the Thrifty
PayLess Record Date, GEI and Kmart owned an aggregate of 24,998,513
(approximately 42%) of the shares of Thrifty PayLess Common Stock then
outstanding. See "The Meetings--Share Ownership of Officers, Directors and
Certain Stockholders." Pursuant to two Stockholder Agreements each dated
October 13, 1996, among Rite Aid, Kmart and certain individual stockholders of
Rite Aid, on the one hand, and among Rite Aid, GEI (collectively, GEI and Kmart
are referred to herein as the "GEI/Kmart Stockholders") and certain individual
stockholders of Rite Aid, on the other (individually, a "GEI/Kmart Stockholder
Agreement" and, collectively, the "GEI/Kmart Stockholder Agreements"), each of
GEI and Kmart agreed, among other things, to vote their respective shares of
Thrifty PayLess Common Stock in favor of the adoption of the Merger Agreement.
Such agreements substantially enhance the likelihood that the Merger will be
consummated. See "The Meetings--Required Vote" and "--GEI/Kmart Stockholder
Agreements." If the Merger had been consummated on the Thrifty PayLess Record
Date, immediately following consummation of the Merger, GEI and Kmart would
have owned approximately 7.2% and 5.3%, respectively, of the outstanding shares
of Rite Aid Common Stock. Pursuant to the GEI/Kmart Stockholder Agreements, GEI
and Kmart are entitled to registration rights with respect to their shares of
Rite Aid Common Stock. Such rights are exercisable before or after the
Effective Time in the case of Kmart and after the Effective Time in the case of
GEI. See "GEI/Kmart Stockholder Agreements--Registration Rights." If Kmart were
to exercise its demand registration rights prior to the Effective Time, it
could be in a position to sell all of its shares of Rite Aid Common Stock
promptly following the Effective Time. Kmart has not notified Rite Aid of its
intentions with respect to such registration rights.     
 
  Purchases of Thrifty PayLess Common Stock by Rite Aid. Pursuant to a letter
agreement, originally dated June 5, 1996 and re-executed as of October 3, 1996
(the "Confidentiality/Standstill Agreement"), Rite Aid
 
                                       5
<PAGE>
 
agreed, among other things, to certain standstill restrictions, including a
restriction on Rite Aid's ability to acquire beneficial ownership of Thrifty
PayLess Common Stock. The Merger Agreement modifies the
Confidentiality/Standstill Agreement to permit (i) the GEI/Kmart Stockholder
Agreements and (ii) the acquisition by Rite Aid of such number of additional
shares of Thrifty PayLess Common Stock ("Rite Aid Permitted Purchases") which,
when added to the number of shares of Thrifty PayLess Common Stock subject to
the GEI/Kmart Stockholder Agreements (approximately 42% of the outstanding
Thrifty PayLess Common Stock), would not exceed 55% of the total number of
shares of outstanding Thrifty PayLess Common Stock (calculated on a fully
diluted basis). Shares of Thrifty PayLess Common Stock so acquired by Rite Aid
would be subject to certain standstill provisions contained in the Merger
Agreement. See "The Merger Agreement--Rite Aid Standstill Provision."
   
  In connection with its approval of the Merger Agreement, the Rite Aid Board
authorized the purchase of Thrifty PayLess Common Stock as described above,
from time to time, in the open market or otherwise. Whether Rite Aid will so
purchase Thrifty PayLess Common Stock will depend upon, among other factors,
the availability and prices therefor. If Rite Aid purchases Thrifty PayLess
Common Stock representing more than 9% of the voting power of all Thrifty
PayLess Common Stock, its shares of Thrifty PayLess Common Stock, coupled with
those subject to the GEI/Kmart Stockholder Agreements, will assure approval of
the adoption of the Merger Agreement by Thrifty PayLess stockholders.     
 
THE MERGER
   
  General. At the effective time of the Merger (the "Effective Time"), Thrifty
PayLess will merge into Rite Aid, with Rite Aid as the surviving corporation in
the Merger. The Effective Time of the Merger will be at such time as the
Certificate of Merger is filed with the Delaware Secretary of State or at such
subsequent date or time as Rite Aid and Thrifty PayLess agree and specify in
the Certificate of Merger. The filing of the Certificate of Merger will occur
as soon as practicable after satisfaction or waiver of the conditions to the
consummation of the Merger set forth in the Merger Agreement unless another
date is agreed to in writing by Rite Aid and Thrifty PayLess (the "Closing
Date").     
   
  The Merger Consideration. At the Effective Time of the Merger, each share of
Thrifty PayLess Common Stock issued and outstanding immediately prior to the
Effective Time (other than shares of Thrifty PayLess Common Stock owned by
Thrifty PayLess as treasury stock, any shares of Thrifty PayLess Common Stock
owned by Rite Aid or any direct or indirect wholly owned subsidiary of Rite Aid
or Thrifty PayLess, and shares of A Common Stock as to which appraisal rights
have been properly exercised and perfected ("Dissenting Thrifty PayLess
Shares") under the Delaware General Corporation Law (the "DGCL")), will by
virtue of the Merger and without any action on the part of the holder thereof
be converted into the right to receive 0.65 shares of duly authorized, validly
issued, fully paid and nonassessable Rite Aid Common Stock. No fractional
shares of Rite Aid Common Stock will be issued in connection with the Merger.
In lieu of any fractional shares, Rite Aid will pay to each holder of Thrifty
PayLess Common Stock otherwise entitled to receive a fractional share, an
amount in cash determined by multiplying the Rite Aid Share Price (defined
below) by the fractional share interest to which the holder would otherwise be
entitled. As used in this Joint Proxy Statement/Prospectus, "Rite Aid Share
Price" means the closing sales price per share of Rite Aid Common Stock on the
NYSE as reported on the NYSE Composite Tape for the date on which the Effective
Time occurs. See "The Merger Agreement--General."     
   
  Certain Conditions to the Merger. Under the Merger Agreement, Thrifty PayLess
is not obligated to consummate the Merger in the event that the average closing
sales price per share of Rite Aid Common Stock as reported on the NYSE
Composite Tape for the five NYSE trading days immediately preceding the Closing
Date (the "Measuring Period") is less than $30.75, provided that this condition
will be satisfied if such average closing sales price is less than $30.75 but
at least $29.00, so long as such average closing sales price does not represent
a diminution below $36.375 which, expressed as a percentage, exceeds the
diminution (if any), also expressed as a percentage, of the average reported
closing Dow Jones Industrial Average ("DJIA") during the     
 
                                       6
<PAGE>
 
   
Measuring Period below 5,934, which was the DJIA closing reported on October 2,
1996 (the "Minimum Price Condition"). Thrifty PayLess has the right, however,
to waive the Minimum Price Condition and any other condition to its obligations
under the Merger Agreement (except for conditions imposed by law, such as the
stockholder approval requirement) at any time, including after the Thrifty
PayLess Stockholder Meeting. The effectiveness of the Merger is also subject to
other conditions. See "The Merger Agreement--Conditions to the Merger." In the
event that the Merger is not consummated prior to April 30, 1997, either party
may terminate the Merger Agreement unless such party has failed to perform its
obligations under the Merger Agreement and such failure causes the Merger not
to be consummated by such date. See "The Merger Agreement--Termination."     
 
  Termination Fees. In the event that any Takeover Proposal has been made known
to Thrifty PayLess or any of its subsidiaries or has been made directly to its
stockholders generally or a third party's intention to make a Takeover Proposal
has been publicly announced and, thereafter, Thrifty PayLess fails to obtain
stockholder approval of the Merger Agreement, Thrifty PayLess will be obligated
to pay $37.5 million to Rite Aid (a "Termination Fee"). Thrifty PayLess will
also be obligated to pay a Termination Fee to Rite Aid in the event that Rite
Aid exercises its right to terminate the Merger Agreement following the
withdrawal or modification in any manner adverse to Rite Aid of the Thrifty
PayLess Board's approval or recommendation of the Merger or the Merger
Agreement or if the Thrifty PayLess Board recommends any Takeover Proposal
other than the Merger. For this purpose, the term "Takeover Proposal" means any
inquiry, proposal or offer from any person relating to any direct or indirect
acquisition or purchase of 14.9% or more of the assets of Thrifty PayLess and
its subsidiaries, or 14.9% or more of any class of equity securities of Thrifty
PayLess or any of its subsidiaries, any tender offer or exchange offer that if
consummated would result in any person beneficially owning 14.9% or more of any
class of equity securities of Thrifty PayLess or any of its subsidiaries, or
any merger, consolidation, business combination, recapitalization, liquidation,
dissolution or similar transaction involving Thrifty PayLess or any of its
Subsidiaries other than the transactions contemplated in the Merger Agreement.
In the event that (i) Thrifty PayLess terminates the Merger Agreement because,
at a stockholder meeting of Rite Aid duly convened therefor and finally
adjourned, Rite Aid stockholders shall not have approved the adoption of the
Merger Agreement or (ii) Thrifty PayLess terminates the Merger Agreement
following a Material Breach of the Merger Agreement by Rite Aid, which breach
or failure is not cured within 30 days after Thrifty PayLess gives notice
thereof, Rite Aid will be obligated to pay a Termination Fee to Thrifty
PayLess. No Termination Fee is payable to either party pursuant to the Merger
Agreement if such party is then in Material Breach of the Merger Agreement. In
each case where a Termination Fee is payable by either Rite Aid or Thrifty
PayLess to the other, the party paying such Termination Fee shall also pay all
reasonable and documented expenses incurred by the party entitled to such
Termination Fee in connection with the Merger, the GEI/Kmart Stockholder
Agreements and the transactions contemplated thereby in an amount not to exceed
$5 million ("Reimbursable Expenses"). See "The Merger Agreement--Termination
Fees."
 
  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 adoption of the Merger Agreement at the Rite Aid Special Meeting.
For a discussion of the factors considered by the Rite Aid Board in reaching
its conclusions, see "The Merger--Rite Aid's Reasons for the Merger;
Recommendations of the Rite Aid Board."
   
  Opinion of DLJ. Donaldson, Lufkin & Jenrette Securities Corporation ("DLJ")
delivered its oral opinion to the Rite Aid Board on October 12, 1996, which was
confirmed by its written opinion dated October 18, 1996, to the effect that as
of such dates the Exchange Ratio is fair to the stockholders of Rite Aid from a
financial point of view. The full text of the DLJ opinion, which sets forth a
description of the assumptions made, matters considered and limitations on the
review undertaken, is attached hereto as Annex B. Rite Aid stockholders are
urged to, and should, read such opinion carefully in its entirety. See "The
Merger--Opinion of DLJ."     
 
                                       7
<PAGE>
 
 
  Recommendation of the Thrifty PayLess Board. The Thrifty PayLess Board has
unanimously approved the Merger Agreement and the transactions contemplated
thereby (including the Merger) as being in the best interests of Thrifty
PayLess and its stockholders. The Thrifty PayLess Board unanimously recommends
that the stockholders of Thrifty PayLess vote in favor of the adoption of the
Merger Agreement and the transactions contemplated thereby at the Thrifty
PayLess Special Meeting. For a discussion of the factors considered by the
Thrifty PayLess Board in reaching its conclusions, see "The Merger--Thrifty
PayLess' Reasons for the Merger; Recommendations of the Thrifty PayLess Board."
 
  Opinion of Goldman Sachs. Goldman, Sachs & Co. ("Goldman Sachs") has
delivered its written opinion to the Thrifty PayLess Board that, as of October
13, 1996, the Exchange Ratio pursuant to the Merger Agreement is fair to the
holders of Thrifty PayLess Common Stock. The full text of the written opinion
of Goldman Sachs, which sets forth assumptions made, matters considered and
limitations on the review undertaken in connection with the opinion, is
attached hereto as Annex C. Holders of Thrifty PayLess Common Stock are urged
to, and should, read such opinion in its entirety. See "The Merger--Opinion of
Goldman Sachs."
   
  Interests of Certain Persons. In considering the recommendation of the
Thrifty PayLess Board with respect to the Merger, stockholders of Thrifty
PayLess should be aware that certain members of Thrifty PayLess management and
of the Thrifty PayLess Board have certain interests in the Merger that are in
addition to the interests of stockholders of Thrifty PayLess generally,
including, among other things, the payments to be made in respect of options
and warrants to acquire Thrifty PayLess Common Stock pursuant to the Merger
Agreement, severance arrangements for employees of Thrifty PayLess located at
its corporate headquarters, consulting agreements with certain Thrifty PayLess
employees, an investment services fee payable to LGA (whose general partners
include certain directors of Thrifty PayLess (or entities controlled by them))
by TPI upon consummation of the Merger, payments to certain Thrifty PayLess
directors under a deferred compensation plan and certain indemnification
obligations of Rite Aid to Thrifty PayLess representatives. See "The Merger--
Interests of Certain Persons and Employee Matters." Such matters were
considered by the Thrifty PayLess Board in approving the Merger Agreement and
the transactions contemplated thereby.     
 
  Certain Federal Income Tax Consequences. The Merger is intended to be a tax-
free reorganization as a result of which no gain or loss will be recognized by
Rite Aid or Thrifty PayLess and no gain or loss will be recognized by Thrifty
PayLess stockholders upon exchange of their Thrifty PayLess Common Stock for
Rite Aid Common Stock pursuant to the Merger Agreement, except in respect of
cash received by holders of Thrifty PayLess Common Stock in lieu of fractional
shares of Rite Aid Common Stock. It is a condition to the consummation of the
Merger that Thrifty PayLess and Rite Aid receive an opinion of Jones, Day,
Reavis & Pogue ("Jones Day"), counsel to Rite Aid, or Irell & Manella LLP,
counsel to Thrifty PayLess, to the effect that, among other things, the Merger
will constitute a "reorganization" within the meaning of Section 368(a) of the
Internal Revenue Code of 1986, as amended (the "Code"). See "The Merger--
Certain Federal Income Tax Consequences."
   
  Certain Thrifty PayLess Indebtedness. Pursuant to the Merger Agreement, Rite
Aid agreed to refinance certain existing debt of Thrifty PayLess. As of the
Effective Time, Rite Aid intends to refinance substantially all of Thrifty
PayLess' obligations under its secured bank facility ($605.4 million aggregate
principal amount and $104.0 million of letters of credit outstanding at
September 29, 1996). In addition, if the Merger is consummated, Rite Aid will
be obligated to offer to repurchase all outstanding TPI 12 1/4% Senior
Subordinated Notes due 2004 (the "TPI Sub Debt") ($195 million aggregate
principal amount outstanding at September 29, 1996) at 101% of the principal
amount thereof (the "Change of Control Offer"). Rite Aid is considering the
possibility of making an offer to purchase all of the TPI Sub Debt at a premium
that is likely to substantially exceed the premium in the Change of Control
Offer, plus accrued and unpaid interest to the date of such purchase. Any such
offer to purchase would be subject to various conditions, including the
consummation of the Merger. There can be no assurance that any such offer to
purchase will be made or as to the timing and terms thereof.     
 
  Accounting Treatment. The Merger will be accounted for under the "purchase"
method of accounting.

APPRAISAL RIGHTS FOR CERTAIN THRIFTY PAYLESS STOCKHOLDERS
   
  Under the DGCL, neither the holders of Rite Aid Common Stock nor the holders
of Thrifty PayLess B Common Stock are entitled to appraisal rights in
connection with the adoption of the Merger Agreement and the transactions
contemplated thereby. Pursuant to Section 262 of the DGCL ("Section 262"), any
holder of record of shares of A Common Stock who does not vote in favor of
adoption of the Merger Agreement, delivers a demand for appraisal prior to the
vote of Thrifty PayLess' stockholders at the Thrifty PayLess Special Meeting on
the Merger Agreement and follows certain other procedures specified in Section
262 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." A copy of Section 262 is attached as Annex D and should be read in its
entirety by holders of A Common Stock.

share, the lowest reported sales price was $35.625 per share and the reported
closing sales price was $35.875 per share. On November 11, 1996, the last full

  Rite Aid has paid regular quarterly dividends on Rite Aid Common Stock since
1968. Since January 29, 1996, Rite Aid has paid regular quarterly dividends on
Rite Aid Common Stock of $0.185 per share. Such rate was $0.15 per share for
each of the fiscal quarters in the table above through the fiscal quarter ended
November 26, 1994 and $0.17 per share for each of the subsequent fiscal
quarters through the fiscal quarter ended March 2, 1996. The payment of
dividends on Rite Aid Common Stock is at the discretion of the Rite Aid Board
and is subject to customary limitations thereon. Rite Aid has agreed in the
Merger Agreement that, prior to the Effective Time, it will not increase its
current dividend rate by a greater percentage than the most recent percentage
increase in its dividend rate prior to the Merger Agreement. Rite Aid also
acknowledged in the Merger Agreement that its intention, as of the date of the
Merger Agreement, was to continue to pay cash dividends at a rate not less than
$0.185 per share.
 
  Thrifty PayLess has not declared any dividends on shares of Thrifty PayLess
Common Stock during its last two fiscal years. In addition, the terms of
Thrifty PayLess' secured bank facility and certain of its other indebtedness
prohibit Thrifty PayLess from paying cash dividends or making distributions on
its capital stock.
 
  Prior to the Thrifty PayLess IPO, there was no established public trading
market for Thrifty PayLess Common Stock. However, in connection with the 1994
PayLess Acquisition, pursuant to a registered offering under the Securities
Act, Thrifty PayLess issued and sold an aggregate of 1,710,000 shares of B
Common Stock (the "Previously Registered Shares"). Thrifty PayLess has been
informed that, from the 1994 PayLess Acquisition through the date of the
Thrifty PayLess IPO, the Previously Registered Shares were traded in
interdealer and over-the-counter bulletin board transactions. The bid
quotations for the Previously Registered Shares during the period from December
18, 1995 through the Thrifty PayLess IPO (the only period during which Thrifty
PayLess has been able to determine that bids were available for such shares)
ranged from a high of $19.58 per share to a low of $12.92 per share (in each
case on a pro forma basis after giving effect to the stock conversion and stock
split that occurred upon consummation of the Thrifty PayLess IPO). Although the
foregoing quotations have been obtained from sources believed to be reliable,
no assurance can be given with respect to the accuracy thereof or as to whether
other bids higher or lower than those set forth above have been quoted. In
addition, such quotations reflect interdealer prices, which may not include
retail mark-up, mark-down or commission, and may not necessarily represent
actual transactions.
 
  There is currently no active public market for the A Common Stock of Thrifty
PayLess. However, pursuant to Thrifty PayLess' Restated Certificate of
Incorporation, at the option of the holder of A Common Stock, shares of A
Common Stock may be converted on a one-for-one basis into shares of B Common
Stock in connection with a sale of such stock. Accordingly, the information
pertaining to market prices of Thrifty PayLess B Common Stock set forth above
may also be applicable to Thrifty PayLess A Common Stock.
 
  Stockholders are urged to obtain current quotations for the market prices of
Rite Aid Common Stock and Thrifty PayLess Common Stock. No assurance can be
given as to the market price of Rite Aid Common Stock or Thrifty PayLess Common
Stock at the Effective Time. The Exchange Ratio is fixed in the Merger
Agreement, and decreases in the market price of Rite Aid Common Stock or
Thrifty PayLess Common Stock will not prevent the consummation of the Merger
except, at Thrifty PayLess' option, as provided in the Minimum Price Condition.
See "The Merger Agreement--Conditions to the Merger." Accordingly, the market
value of the shares of Rite Aid Common Stock that holders of Thrifty PayLess
Common Stock will receive in the Merger may vary significantly from the prices
shown above.

                      UNAUDITED COMPARATIVE PER SHARE DATA
 
  The following table sets forth certain historical and pro forma equivalent
per share data for Rite Aid Common Stock for Rite Aid's 26 weeks ended August
31, 1996 and fiscal year ended March 2, 1996, and certain historical per share
data for Thrifty PayLess Common Stock for Thrifty PayLess' 26 weeks ended June
30, 1996 and 52 weeks ended December 31, 1995. The information presented herein
should be read in conjunction with the selected historical financial data and
unaudited pro forma condensed consolidated financial statements found elsewhere
in this Joint Proxy Statement/Prospectus (see "--Selected Historical Financial
Data of Rite Aid" and "--Selected Historical Financial Data of Thrifty
PayLess") as well as the historical financial information incorporated herein.
See "Incorporation of Certain Documents by Reference." Equivalent historical
per share data are derived from audited and unaudited financial statements of

(1) The pro forma financial information has been prepared assuming the Merger
    occurred at the beginning of the respective periods using a 0.65 Exchange
    Ratio of shares of Rite Aid Common Stock for shares of Thrifty PayLess
    Common Stock.
(2) The per share amounts used in the pro forma calculations were computed by
    adding the number of 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) Net income for the 26 week period ended August 31, 1996 reflects a
    nonrecurring, pre-tax charge of $16.1 million to write off expenses
    associated with Rite Aid's attempted acquisition of Revco D.S. Inc. The
    charge resulted in an after-tax effect of $9.9 million or $0.12 per share.

(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 periods (83.8 in fiscal year 1996, 84.8 in fiscal year
    1995, 88.0 in fiscal year 1994, 87.9 in fiscal year 1993 and 86.9 in fiscal
    year 1992 and 83.9 and 83.8 for the 26 week periods ended August 31, 1996
    and September 2, 1995, respectively). Net income for the 26 week period
    ended August 31, 1996 reflects a non-recurring, pre-tax charge of $16.1 to
    write-off expenses associated with the attempted acquisition of Revco D.S.
    Inc. The charge resulted in an after tax effect of $9.9 or $.12 per share.
(2) Depreciation and amortization expenses were $97.0 for fiscal year 1996,
    $82.7 for fiscal year 1995, $76.3 for fiscal year 1994, $72.0 for fiscal
    year 1993, $69.4 for fiscal year 1992, $53.6 for the 26 weeks ended August
    31, 1996 and $46.7 for the 26 weeks ended September 2, 1995. 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: three to 15 years. Accelerated methods are used for
    income tax purposes.

(3) As part of its restructuring strategy announced in 1994, Rite Aid
    concentrated its focus and resources entirely on the drug store segment and
    the Rite Aid Board authorized the sale of Rite Aid's four non-drug store
    businesses. The businesses sold were (i) ADAP, an auto parts retailer with
    96 stores, (ii) Encore Books ("Encore"), which operated 98 book stores,
    (iii) Concord Custom Cleaners ("Concord"), which operated 168 cleaning
    outlets, and (iv) Sera-Tec Biologicals ("Sera-Tec"), which operated 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 aggregate net proceeds received for the three dispositions
    was $75.8, after taxes and expenses of $24.3. The resulting aggregate
    after-tax loss of $12.3 was recorded to the reserve for loss on disposal of
    discontinued operations. The sale of ADAP was completed in the first
    quarter of fiscal 1996. The aggregate consideration for the ADAP sale was
    approximately $59.3 and the remaining reserve amount of $13.3 for loss on
    disposal of ADAP was adequate.
 
  A pre-tax provision of $42.0 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 $16.4 income tax
  benefit. The provision includes after-tax income from operations during the
  phaseout period of $1.0.
 
  Net sales for the discontinued operations were $273.1, $251.5 and $217.8
  for Rite Aid's fiscal years 1994, 1993 and 1992, respectively. The interest
  expense allocation was $4.5 in fiscal year 1994, $3.5 in fiscal year 1993
  and $3.4 in fiscal year 1992. Assets and liabilities of the discontinued
  operations have been reclassified to identify them separately on Rite Aid's
  consolidated balance sheet. The net current assets of discontinued
  operations principally consisted of inventories and for fiscal year 1994
  included the $42.0 disposition reserve with applicable income tax benefit
  of $16.4. The net non-current assets of discontinued operations were
  primarily 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. See "Incorporation of
  Certain Documents by Reference."

             SELECTED HISTORICAL FINANCIAL DATA OF THRIFTY PAYLESS
                                 (IN MILLIONS)
 
  The following table presents selected historical consolidated financial data
of Thrifty PayLess for the periods indicated. Such financial data is derived
from financial data of Thrifty PayLess contained in reports filed by it
pursuant to the requirements of the Exchange Act, which reports are
incorporated herein by reference (see "Incorporation of Certain Documents by
Reference"). Thrifty PayLess had no operations prior to the 1992 Thrifty
Acquisition. Accordingly, financial information for the year ended December 29,
1991 and the 39 weeks ended September 27, 1992 is that of Thrifty Corporation
("Predecessor Thrifty PayLess"). The Predecessor Thrifty PayLess periods also
include the operations of Pay'n Save until July 25, 1992, when it was sold to
PayLess. Thrifty PayLess' financial data include the operations of PayLess
beginning on April 20, 1994, the date of the 1994 PayLess Acquisition.
Accordingly, comparisons of periods may not be meaningful. Results of
operations for the 39-week periods ended July 2, 1995 and June 30, 1996 are
derived from unaudited interim financial statements and are not necessarily
indicative of results of operations for a full fiscal year.

              SELECTED UNAUDITED SUMMARY PRO FORMA FINANCIAL DATA
                                 (IN MILLIONS)
 
  The following selected unaudited summary pro forma financial data for Rite
Aid give effect to the Merger, the Southeast Dispositions, the Bi-Mart
divestiture and certain related adjustments described in "Unaudited Pro Forma
Condensed Consolidated Financial Data." The transactions are reflected in the
unaudited pro forma condensed consolidated balance sheet data as if they
occurred as of August 31, 1996, and in the unaudited pro forma condensed
consolidated operating statement data as if they occurred as of the beginning
of the periods presented. The Merger will be accounted for under the purchase
method of accounting. The unaudited pro forma condensed consolidated financial
statements contained herein are prepared for illustrative purposes only and are
not necessarily indicative of the financial position or results of operations
that might have occurred had the applicable transactions actually taken place
on the dates indicated, or of future results of operations or financial
positions of the stand alone or combined entities. The unaudited pro forma
condensed consolidated financial statements do not reflect any synergies
expected by Rite Aid management to be realized after the Merger (see "The
Merger--Rite Aid's Reasons for the Merger; Recommendation of the Rite Aid
Board"); transaction costs relating to the Southeast Dispositions, inasmuch as
such costs are non-recurring; or any effect that purchases of Thrifty PayLess
Common Stock by Rite Aid prior to the consummation of the Merger would have on
such financial information. The unaudited pro forma condensed consolidated
financial statements are based on the historical consolidated financial
statements of Rite Aid and Thrifty PayLess and should be read in conjunction
with (i) such historical financial statements and the notes thereto, which are
incorporated by reference in this Joint Proxy Statement/Prospectus, (ii) the

                                 THE MEETINGS
 
RITE AID SPECIAL MEETING
   
  At the Rite Aid Special Meeting, the stockholders of Rite Aid will consider
and vote upon a proposal to approve adoption of the Merger Agreement and the
issuance of Rite Aid Common Stock to the holders of Thrifty PayLess Common
Stock pursuant thereto. Pursuant to the Merger Agreement, (i) Thrifty PayLess
will merge with and into Rite Aid, with Rite Aid as the surviving corporation
in the Merger, (ii) subject to certain exceptions, each outstanding share of
Thrifty PayLess Common Stock will be converted into 0.65 of a share of Rite
Aid Common Stock, resulting in the issuance of an aggregate of approximately
38.7 million shares of Rite Aid Common Stock in exchange for an aggregate of
approximately 59.5 million shares of Thrifty PayLess Common Stock, (iii) each
outstanding option or warrant to acquire shares of Thrifty PayLess Common
Stock (collectively, "Thrifty PayLess Stock Options") will be converted into a
right to receive an amount of cash equal to (a) 65% of the Rite Aid Share
Price, minus the exercise price per share under the applicable Thrifty PayLess
Stock Option, times (b) the number of shares of Thrifty PayLess Common Stock
purchasable upon exercise of such Thrifty PayLess Stock Option, and (iv) Rite
Aid's Certificate of Incorporation will be amended in order, among other
things, to increase the number of authorized shares of Rite Aid Common Stock
from 240 million to 300 million. See "The Merger--Amendment of Rite Aid
Certificate of Incorporation."     
 
  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 "FOR"
ADOPTION OF THE MERGER AGREEMENT. See "The Merger--Rite Aid's Reasons for the
Merger; Recommendation of the Rite Aid Board."
 
THRIFTY PAYLESS SPECIAL MEETING
   
  At the Thrifty Payless Special Meeting, the stockholders of Thrifty PayLess
will consider and vote upon a proposal to approve adoption of the Merger
Agreement. Pursuant to the GEI/Kmart Stockholder Agreements, the GEI/Kmart
Stockholders have agreed to vote in favor of adoption of the Merger Agreement.
Such agreements, coupled with any purchases of Thrifty PayLess Common Stock by
Rite Aid prior to the Effective Time, substantially enhance the likelihood
that the Merger will be consummated. See "--Required Vote;" "--Share Ownership
of Officers, Directors and Certain Stockholders" and "GEI/Kmart Stockholder
Agreements."     
 
  The Thrifty PayLess Board has unanimously approved the Merger Agreement and
the transactions contemplated thereby (including the Merger) as being in the
best interests of the stockholders of Thrifty PayLess. THE THRIFTY PAYLESS
BOARD UNANIMOUSLY RECOMMENDS THAT THE STOCKHOLDERS OF THRIFTY PAYLESS VOTE
"FOR" ADOPTION OF THE MERGER AGREEMENT. See "The Merger--Thrifty PayLess'
Reasons for the Merger; Recommendation of the Thrifty PayLess Board."
 
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. Similarly, the
holders of a majority of the shares of Thrifty PayLess Common Stock
outstanding and entitled to vote must be present in person or represented by
proxy at the Thrifty PayLess Special Meeting in order for a quorum to be
present. Shares represented by proxies which are marked "abstain" will be
counted as shares present for each respective Special Meeting 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 either Special Meeting, it is
expected that such Special Meeting will be adjourned or postponed to solicit
additional proxies, except that shares represented by proxies which have
 
                                      17
<PAGE>
 
been voted "against," or have abstained with respect to the proposal to adopt
the Merger Agreement and the transactions contemplated thereby (including the
Merger), will not be used to vote "for" postponement or adjournment of either
Special Meeting for the purpose of allowing additional time for soliciting
additional votes "for" such adoption.
 
RECORD DATE; VOTING RIGHTS
   
  Only holders of record of Rite Aid Common Stock at the close of business on
the Rite Aid Record Date are entitled to receive notice of and to vote at the
Rite Aid Special Meeting or at any adjournments or postponements thereof. At
the close of business on the Rite Aid Record Date, there were 83,928,120
shares of Rite Aid Common Stock outstanding, each of which entitles the
registered holder thereof to one vote.     
   
  Only holders of record of Thrifty PayLess Common Stock at the close of
business on the Thrifty PayLess Record Date are entitled to receive notice of
and to vote at the Thrifty PayLess Special Meeting or at any adjournments or
postponements thereof. At the close of business on the Thrifty PayLess Record
Date, there were 59,501,807 shares of Thrifty PayLess Common Stock outstanding
(consisting of 16,804,002 shares of A Common Stock and 42,697,805 shares of B
Common Stock), each of which entitles the registered holder thereof to one
vote with respect to adoption of the Merger Agreement.     
 
REQUIRED VOTE
 
  Adoption of the Merger Agreement by Rite Aid stockholders will require the
affirmative vote of a majority of the shares of Rite Aid Common Stock
outstanding as of the Rite Aid Record Date entitled to vote thereon. Adoption
of the Merger Agreement by Thrifty PayLess stockholders will require the
affirmative vote of a majority of the shares of A Common Stock and B Common
Stock outstanding as of the Thrifty PayLess Record Date entitled to vote
thereon, voting together as a single class.
 
SHARE OWNERSHIP OF OFFICERS, DIRECTORS AND CERTAIN STOCKHOLDERS
   
  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 4,814,062 (approximately 5.7%) of the shares of Rite Aid
Common Stock then outstanding.     
   
  At the close of business on the Thrifty PayLess Record Date, directors and
executive officers of Thrifty PayLess and their affiliates were the beneficial
owners of an aggregate of 14,748,894 (approximately 24.8%) of the shares of
Thrifty PayLess Common Stock then outstanding (which amount includes the
14,376,264 shares owned by GEI, as to which Leonard I. Green, Jonathan D.
Sokoloff and Jennifer Holden Dunbar, each a director of Thrifty PayLess, may
be considered a beneficial owner because they (or entities controlled by them)
are general partners of LGP, which is GEI's general partner). As of the
Thrifty PayLess Record Date, GEI and Kmart owned an aggregate of 24,998,513 of
the shares of Thrifty PayLess Common Stock then outstanding (approximately
42%) . Pursuant to the GEI/Kmart Stockholder Agreements, each of GEI and Kmart
agreed, among other things, to vote its respective shares in favor of the
adoption of the Merger Agreement, thereby substantially enhancing the
likelihood that the Merger will be consummated. See "GEI/Kmart Stockholder
Agreements." If the Merger had been consummated on the Thrifty PayLess Record
Date, immediately following consummation of the Merger, GEI and Kmart would
have owned approximately 7.2% and 5.3%, respectively, of the outstanding
shares of Rite Aid Common Stock. Pursuant to the GEI/Kmart Stockholder
Agreements, GEI and Kmart are entitled to registration rights with respect to
their shares of Rite Aid Common Stock. Such rights are exercisable before or
after the Effective Time in the case of Kmart and after the Effective Time in
the case of GEI. See "GEI/Kmart Stockholder Agreements--Registration Rights."
If Kmart were to exercise its demand registration rights prior to the
Effective Time, it could be in a position to sell all of its shares of Rite
Aid Common Stock promptly following the Effective Time. Kmart has not notified
Rite Aid of its intentions with respect to such registration rights.     
 
                                      18

  In connection with its approval of, and as permitted by, the Merger
Agreement, the Rite Aid Board authorized the purchase of Thrifty PayLess
Common Stock from time to time in the open market or otherwise up to the
amount of the Rite Aid Permitted Purchases. Whether Rite Aid will so purchase
Thrifty PayLess Common Stock will depend upon, among other factors, the
availability and prices therefor. If Rite Aid purchases Thrifty PayLess Common
Stock representing more than 9% of the voting power of all Thrifty PayLess
Common Stock and votes such shares in favor of adoption of the Merger
Agreement, such actions, coupled with the voting covenants under the GEI/Kmart
Stockholder Agreements, will assure approval of the adoption of the Merger
Agreement by Thrifty PayLess stockholders. Shares of Thrifty PayLess Common
Stock so acquired by Rite Aid would be subject to certain standstill
provisions contained in the Merger Agreement. See "The Merger Agreement--Rite
Aid Standstill Provision."     
 
PROXIES
 
  All shares represented by properly executed proxies in the enclosed form
which are received in time for the respective 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 REPRESENTED BY THE PROXY WILL BE VOTED FOR THE ADOPTION OF THE MERGER
AGREEMENT AT THE RESPECTIVE SPECIAL MEETING. Abstentions and broker non-votes
will have the effect of a vote cast against the Merger Agreement at the
respective Special Meeting.
 
  In addition, while it is not expected that any other matter other than those
referred to herein will be brought before either of the Special Meetings, the
persons designated in such proxy will have discretion to vote upon any matter
properly presented at the respective Special Meeting. 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
or Thrifty PayLess, as the case may be, by signing and returning a later dated
proxy to the Secretary of Rite Aid or Thrifty PayLess, as the case may be, or
by voting in person at the respective Special Meeting. Attendance at the
respective 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 and the
Thrifty PayLess 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 and Thrifty PayLess. 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 and Thrifty PayLess have retained W.F. Doring & Co. Inc. ("Doring")
and MacKenzie Partners, Inc. ("MacKenzie"), respectively, to aid in the
solicitation of proxies. Each of Doring and MacKenzie will receive reasonable
and customary compensation for its services estimated at $5,000 and $7,500,
respectively, and will be reimbursed for certain reasonable out-of-pocket
expenses by Rite Aid and Thrifty PayLess.     
 
                                  THE MERGER
 
GENERAL
 
  The description of the Merger and the Merger Agreement contained in this
Joint Proxy Statement/Prospectus does not purport to be complete and is
qualified in its entirety by reference to the Merger Agreement, a copy of
which is attached hereto as Annex A and incorporated herein by reference.
   
  At the Effective Time, Thrifty PayLess will merge into Rite Aid, with Rite
Aid as the surviving corporation in the Merger. The Merger will become
effective at such time as the Certificate of Merger is filed with the Delaware
Secretary of State or at such subsequent date or time as Rite Aid and Thrifty
PayLess agree and specify in the Certificate of Merger. The filing of the
Certificate of Merger will occur as soon as practicable after satisfaction or
waiver of the conditions to the consummation of the Merger set forth in the
Merger Agreement unless another date is agreed to in writing by Rite Aid and
Thrifty PayLess.     
 
                                      19
<PAGE>
 
  At the Effective Time, each share of Thrifty PayLess Common Stock issued and
outstanding immediately prior to the Effective Time (other than shares of
Thrifty PayLess Common Stock owned by Thrifty PayLess as treasury stock,
shares of Thrifty PayLess Common Stock owned by Rite Aid or any direct or
indirect wholly owned subsidiary of Rite Aid or Thrifty PayLess, and
Dissenting Thrifty PayLess Shares), will by virtue of the Merger and without
any action on the part of the holder thereof be converted into the right to
receive 0.65 shares of duly authorized, validly issued, fully paid and
nonassessable shares of Rite Aid Common Stock.
 
BACKGROUND OF THE MERGER
   
  On June 3, 1996, a representative of DLJ informed representatives of GEI of
Rite Aid's possible interest in Thrifty PayLess and the intent of Rite Aid
representatives to visit numerous Thrifty PayLess store sites. On June 5,
1996, Rite Aid entered into the Confidentiality/Standstill Agreement. However,
no material information was provided pursuant to such agreement at such time.
On June 10, 1996, a representative of DLJ contacted Leonard I. Green, the
founding partner of LGA (GEI's general partner) and the Chairman of the Board
of Thrifty PayLess, to discuss the possibility of a meeting between Mr. Green
and Martin L. Grass, the Chairman and Chief Executive Officer of Rite Aid.
    
       
  On June 26, 1996, Mr. Grass and Mr. Green, together with certain
representatives of DLJ and Goldman Sachs, met to discuss a possible business
combination transaction involving Thrifty PayLess and Rite Aid. Mr. Green
informed Mr. Grass at that meeting, among other things, that GEI was not at
that time considering the possibility of divesting its investment in Thrifty
PayLess, but that it was possible that the Thrifty PayLess Board would
consider a merger or other business combination transaction if the terms
thereof were sufficiently attractive to Thrifty PayLess and its stockholders.
Mr. Green also informed Mr. Grass that no confidential information regarding
Thrifty PayLess would be provided to Rite Aid until a concrete proposal had
been made by Rite Aid.
 
  On July 12, 1996, at Rite Aid's request, Messrs. Grass and Green met again
to discuss a proposal of Mr. Grass. Mr. Grass proposed that Rite Aid acquire
Thrifty PayLess pursuant to a zero-premium stock-for-stock merger. Mr. Green
informed Mr. Grass that such proposal was not acceptable to GEI and, in his
judgment, would not be acceptable to the Thrifty PayLess Board.
 
  On September 30, 1996, at Rite Aid's request, Messrs. Grass and Green met
together with representatives of DLJ and Goldman Sachs and other
representatives of Rite Aid. At this meeting, Mr. Grass presented a proposal
for consideration and discussions were held regarding the businesses,
operations, financial matters, strategies, prospects and personnel of each
company. On October 2, 1996, Messrs. Grass and Green met to discuss Mr. Grass'
most recent proposal. At this meeting, Messrs. Grass and Green discussed the
principal terms for a transaction that they would be willing to submit to
their respective Boards of Directors, including an exchange ratio and a
minimum price condition, and agreed upon a timetable designed to permit the
two companies to complete their due diligence examinations, agree upon
definitive documentation and take other actions so that a decision could be
made by their respective Boards of Directors as to whether to pursue the
possible transaction over an approximately ten-day period.
 
  During the ensuing ten-day period, financial, legal, accounting and
management representatives of Rite Aid, Thrifty PayLess and GEI met or
otherwise pursued the possible transaction in order to carry out due diligence
reviews, to discuss the financial, structural, legal and other terms of a
possible transaction and to negotiate the terms of a merger agreement,
GEI/Kmart stockholder agreements and certain other matters. On October 8,
1996, GEI contacted Kmart to advise it of the ongoing negotiations and to
afford it the opportunity of reviewing, and participating in the negotiations
regarding, its respective stockholder agreement. Thereafter, Kmart
participated in the negotiations with respect thereto.
 
  A regular meeting of the Rite Aid Board was held on October 9, 1996, at
which, among other subjects, the possible acquisition of Thrifty PayLess was
reviewed with the Rite Aid Board by Rite Aid's senior management, with the
assistance of Jones Day and DLJ. The presentations to and discussions by the
Rite Aid Board were
 
                                      20
<PAGE>
 
wide ranging, and included, among other things, (i) a review by senior
management of the discussions conducted to date with representatives of
Thrifty PayLess, (ii) a review by Rite Aid's senior management of the
conditions in the drug store industry in North America, the strategic options
available to Ride Aid and the likelihood of future consolidation in the drug
store industry in North America, (iii) a discussion of Rite Aid's strategy of
focusing on geographic areas in which Rite Aid has or can be expected to
obtain a position of market leadership, and the relationship of the Merger and
the Southeast Dispositions to that strategy, (iv) a review by senior
management of Thrifty PayLess' business, operations, financial condition,
results of operations, strategies, prospects and personnel, (v) a discussion
by Jones Day of the terms of the possible transaction, and (vi) a presentation
by DLJ of its views of the possible financial benefits to Rite Aid of, and
likely stock market reactions to, a possible acquisition of Thrifty PayLess by
Rite Aid, together with a review of the transaction from the perspective of
Rite Aid's stockholders.
   
  A special meeting of the Thrifty PayLess Board was held on October 11, 1996,
at which the proposed strategic merger of Thrifty PayLess with Rite Aid was
reviewed by the Thrifty PayLess Board with the assistance of Thrifty PayLess'
financial advisor, Goldman Sachs, and its legal counsel, Irell & Manella LLP.
The presentations to and discussions by the Thrifty PayLess Board were wide
ranging and included, among other things, the following: (i) a review of
discussions conducted to date between representatives of Thrifty PayLess and
Rite Aid, which was presented by such Thrifty PayLess representatives and
Irell & Manella LLP; (ii) a presentation by Goldman Sachs of its financial
analyses and, based upon information provided by Rite Aid, information
regarding the business, results of operations and financial condition of Rite
Aid and Rite Aid's management's expectations of the potential synergies and
economies of scale that Rite Aid expected to arise from the proposed merger;
and (iii) a presentation by Irell & Manella LLP regarding the then-current
status of the negotiations regarding the material terms of the Merger
Agreement and related transactions, including the Exchange Ratio, closing
conditions, termination rights and fees and various matters set forth herein
under "The Merger--Interests of Certain Persons and Employee Matters"
(including the treatment of Thrifty PayLess Stock Options and severance
arrangements), and of the material terms of the proposed GEI/Kmart Stockholder
Agreements, including the voting provisions thereof, as well as various other
legal matters pertinent to the proposed merger, including antitrust and tax
matters and the fiduciary duties of the Thrifty PayLess Board in evaluating
and acting upon the proposed merger. During the course of the meeting, the
Thrifty PayLess Board was provided, among other things, drafts of the Merger
Agreement and the GEI/Kmart Stockholder Agreements.     
   
  A special meeting of the Rite Aid Board was held on October 12, 1996, at
which the possible business combination was reviewed with the Rite Aid Board
by Rite Aid's senior management with the assistance of Jones Day and DLJ. At
the meeting, the Rite Aid Board had presentations regarding, and discussed
various matters, including, among other things, the course of the discussions
with Thrifty PayLess and the terms of the possible transaction, including a
review by Jones Day of the termination provisions of the draft Merger
Agreement, the terms of the GEI/Kmart Stockholder Agreements and all other
material terms of the transaction. Representatives of DLJ then updated such
firm's financial analysis of the combination previously presented at the
October 9, 1996 meeting and informed the Rite Aid Board, which advice was
subsequently confirmed in writing, that, in the opinion of DLJ, the Exchange
Ratio was fair to the stockholders of Rite Aid from a financial point of view.
DLJ subsequently confirmed its opinion by delivery of its written opinion
dated October 18, 1996. See "The Merger--Opinion of DLJ." Following
discussion, the Rite Aid Board, by unanimous vote, approved the Merger
Agreement, the GEI/Kmart Stockholder Agreements and the transactions
contemplated thereby.     
 
  A special meeting of the Thrifty PayLess Board was held on October 13, 1996,
at which the proposed strategic merger of Thrifty PayLess into Rite Aid was
again reviewed by the Thrifty PayLess Board with the assistance of Goldman
Sachs and Irell & Manella LLP. The presentations to and discussions by the
Thrifty PayLess Board were wide ranging and included, among other things, the
following: (i) a presentation by Irell & Manella LLP regarding various matters
that it had presented during the October 11, 1996 special meeting of the
Thrifty PayLess Board, including a discussion of the material terms of the
Merger Agreement and the proposed GEI/Kmart Stockholder Agreements and
revisions thereto since the date of the prior special meeting, as well as an
overview of the due diligence investigation that had been conducted with
respect to Rite Aid; (ii) a
 
                                      21
<PAGE>
 
   
presentation by Goldman Sachs of its financial analyses described under "The
Merger--Opinion of Goldman Sachs;" and (iii) a review of developments with
respect to the various matters set forth under "The Merger--Interests of
Certain Persons" (including various enhancements to the severance arrangements
that had been negotiated for the benefit of Thrifty PayLess employees and
consideration of the LGA investment services fee). Goldman Sachs then
delivered its opinion to the Thrifty PayLess Board that, as of October 13,
1996, the Exchange Ratio pursuant to the Merger Agreement is fair to the
holders of Thrifty PayLess Common Stock. Following discussion, the Thrifty
PayLess Board, by unanimous vote, approved the Merger Agreement and the
transactions contemplated thereby (including the Merger).     
 
  Following the Thrifty Payless Board meeting on October 13, 1996,
representatives of Rite Aid and Thrifty PayLess executed the Merger Agreement,
GEI and Kmart executed their respective GEI/Kmart Stockholder Agreements (as
did Rite Aid) and, on October 14, 1996, Rite Aid announced the transaction.
 
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 Merger Agreement. In reaching
its conclusion, the Rite Aid Board considered a number of factors, including:
 
  . The judgement and advice of Rite Aid's senior management, including in
    respect of the conditions in the drug store industry in North America,
    the strategic options available to Rite Aid and the likelihood of future
    consolidation in the drug store industry in North America.
 
  . Rite Aid's strategy of focusing on geographic areas in which Rite Aid is
    or can become a market leader, and the relationship of the Merger and the
    Southeast Dispositions to this strategy.
 
  . The analyses prepared by DLJ and the oral opinion of DLJ presented to the
    Rite Aid Board on October 12, 1996 and confirmed in writing on October
    18, 1996, to the effect that as of such dates the Exchange Ratio is fair
    to the stockholders of Rite Aid from a financial point of view. A copy of
    the written opinion dated October 18, 1996 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" and "--
    Background of the Merger."
 
  . The financial condition, results of operations and cash flows of Rite Aid
    and Thrifty PayLess, both on a historical and a prospective basis.
 
  . The terms and conditions of the Merger Agreement, including the amount
    and form of consideration to be paid pursuant to the Merger Agreement.
 
  . Historical market prices and trading information with respect to Rite Aid
    Common Stock and Thrifty PayLess Common Stock.
     
  . The Rite Aid Board's belief that the transaction would be accomplished on
    a tax-free basis for federal income tax purposes (other than cash
    received in lieu of fractional shares) and accounted for as a "purchase"
    transaction.     
 
  . The GEI/Kmart Stockholder Agreements which provide, among other things,
    for the GEI/Kmart Stockholders to vote their respective shares of Thrifty
    PayLess Common Stock in favor of adoption of the Merger Agreement.
 
  . The other factors mentioned below in this section.
 
The foregoing discussion of the information and factors considered and given
weight by the Rite Aid Board is not intended to be exhaustive. In view of the
variety of factors considered in connection with its evaluation of the Merger,
the Rite Aid Board did not find it practicable to and did not attempt to rank
or assign relative weights to the foregoing factors. In addition, individual
members of the Rite Aid Board may have given different weights to different
factors.

  Rite Aid's acquisition of Thrifty PayLess pursuant to the Merger is an
integral part of Rite Aid's strategy to operate drug stores in large, fast-
growing metropolitan areas. Following the Merger, as soon as reasonably
practicable, Rite Aid expects to divest Bi-Mart, to rename all Thrifty PayLess
stores "Rite Aid" and integrate them with Rite Aid's operations, to refinance
substantially all of Thrifty PayLess' debt (to the extent practicable) and to
close Thrifty PayLess' Wilsonville, Oregon headquarters. Rite Aid expects the
elimination of duplicative overhead expenses and the combined company's
enhanced purchasing efficiencies to result in annual cost savings of at least
$65.0 million. Rite Aid also believes that there are other cost-savings
opportunities presented by the Merger (including lowering Thrifty PayLess'
historical debt expense, distribution costs and inventory shrinkage rate), as
well as opportunities for enhanced revenue growth from the increased scale of
operations and geographic diversity which Rite Aid will have after the Merger.
In addition, the application of Rite Aid's systems and technology to Thrifty
PayLess' operations should result in greater efficiencies. Giving effect to
expected cost reductions resulting from the Merger, the Merger is expected to
be accretive to Rite Aid's earnings in the fiscal year ended February 28, 1998
and thereafter.     
 
  THE RITE AID BOARD UNANIMOUSLY RECOMMENDS THAT THE HOLDERS OF RITE AID
COMMON STOCK VOTE "FOR" ADOPTION OF THE MERGER AGREEMENT.
 
OPINION OF DLJ
 
  Rite Aid engaged DLJ to act as its financial advisor in connection with the
transactions contemplated by the Merger Agreement based upon DLJ's
qualifications, expertise and reputation, as well as DLJ's prior investment
banking relationship and familiarity with Rite Aid and Thrifty PayLess. On
October 12, 1996, DLJ rendered an oral opinion to the Rite Aid Board which was
confirmed by delivery of its written opinion dated October 18, 1996 (the "DLJ
Opinion") to the effect that, as of such date, and based upon and subject to
the assumptions, limitations and qualifications set forth in such opinion, the
Exchange Ratio was fair to the stockholders of Rite Aid from a financial point
of view.
 
  THE FULL TEXT OF THE DLJ OPINION IS SET FORTH AS ANNEX B TO THIS JOINT PROXY
STATEMENT/PROSPECTUS AND SHOULD BE READ CAREFULLY IN ITS ENTIRETY, INCLUDING
WITHOUT LIMITATION THE DESCRIPTIONS OF THE PROCEDURES FOLLOWED, ASSUMPTIONS
MADE, OTHER MATTERS CONSIDERED AND LIMITATIONS OF THE REVIEW UNDERTAKEN IN
ARRIVING AT SUCH OPINION. THE DLJ OPINION ADDRESSES THE FAIRNESS OF THE
EXCHANGE RATIO TO THE STOCKHOLDERS OF RITE AID FROM A FINANCIAL POINT OF VIEW
AND DOES NOT CONSTITUTE A RECOMMENDATION TO ANY STOCKHOLDER OF RITE AID OR
THRIFTY PAYLESS AS TO HOW SUCH STOCKHOLDER SHOULD VOTE AT THE RESPECTIVE
SPECIAL MEETING.
 
  The DLJ Opinion does not constitute an opinion as to the price at which Rite
Aid Common Stock will actually trade at any time. The type and amount of
consideration was determined in arm's length negotiations between Rite Aid and
Thrifty PayLess in which negotiations DLJ advised Rite Aid. No restrictions or
limitations were imposed upon DLJ with respect to the investigations made or
procedures followed by DLJ in rendering its opinion. In arriving at its
opinion, DLJ reviewed the Merger Agreement as well as financial and other
information that was publicly available or furnished to it by Rite Aid and
Thrifty PayLess including information provided during discussions with their
respective managements. Included in the information provided during
discussions with the respective managements were certain internal financial
analyses and forecasts for Rite Aid and Thrifty PayLess prepared by their
respective managements. In addition, DLJ compared certain financial and
securities data of Rite Aid and Thrifty PayLess with various other companies
whose securities are traded in public markets, reviewed the historical stock
prices and trading volumes of the Thrifty PayLess B Common Stock and Rite Aid
Common Stock, reviewed prices and premiums paid in certain other business
combinations and conducted such other financial studies, analyses and
investigations as DLJ deemed appropriate for purposes of rendering its
opinion.
 
  In rendering its opinion, DLJ relied upon and assumed the accuracy,
completeness and fairness of all of the financial and other information that
was available to it from public sources, that was provided to it by Rite Aid
and Thrifty PayLess or their respective representatives, or that was otherwise
reviewed by it. DLJ relied upon the estimates of the management of Rite Aid of
the operating synergies and interest expense savings achievable
 
                                      23
<PAGE>
 
as a result of the Merger. DLJ also assumed that the financial analyses and
forecasts regarding Rite Aid and Thrifty PayLess supplied to it by their
respective managements were reasonably prepared on the basis reflecting the
best currently available estimates and judgments of the management of Rite Aid
and Thrifty PayLess, respectively, as to the future operating and financial
performance of Rite Aid and Thrifty PayLess, respectively.
 
  The DLJ Opinion is necessarily based on economic, market, financial and
other conditions as they exist on, and on information made available to it as
of, the date of its opinion. DLJ does not have any obligation to update,
revise and reaffirm its opinion.
 
  The following is a brief summary of the analyses performed by DLJ in
connection with the DLJ Opinion to the Rite Aid Board. All analyses discussed
below, unless otherwise indicated, exclude the estimated operating synergies
and interest expense savings ("Synergies") provided by the management of Rite
Aid.
 
  Common Stock Performance Analysis. DLJ's analysis of Rite Aid's Common Stock
performance consisted of a historical analysis of closing prices and trading
volumes for the 12 months ended October 11, 1996. In the 12 months ended
October 11, 1996, the Rite Aid Common Stock reached a high of $37.00 per share
and a low of $26.88 per share. On October 11, 1996, the closing price of Rite
Aid Common Stock of $35.88 per share was at the high end of such range. DLJ's
analysis of Thrifty PayLess' Common Stock performance consisted of a
historical analysis of Thrifty PayLess' closing prices and trading volumes for
the period beginning April 16, 1996 and ending on October 11, 1996. Since the
Thrifty PayLess IPO on April 16, 1996, Thrifty PayLess B Common Stock reached
a high of $18.88 per share and a low of $13.38 per share. On October 11, 1996,
the closing price of Thrifty PayLess B Common Stock of $18.38 per share was at
the high end of such range. Since April 16, 1996, Thrifty PayLess B Common
Stock has outperformed the S&P 400. In addition, DLJ compared the S&P 400
relative to a comparable company index, which included Rite Aid, Thrifty
PayLess, Revco, Walgreen, CVS, Longs Drug Stores, Eckerd Corporation and Arbor
Drugs from October 11, 1991 to October 11, 1996.
 
  Historical Exchange Ratio Analysis. DLJ analyzed the historical exchange
ratio between Rite Aid Common Stock and Thrifty PayLess Common Stock over
several time periods. For each period selected, the high, low and average
exchange ratios were calculated. The time periods (ending on October 11, 1996)
selected for analysis were as follows: since the Thrifty PayLess IPO (April
16, 1996), last 120 days, last 60 days, last 30 days and last 10 days. The
average exchange ratio for each aforementioned time period was .45, .49, .50,
 .51 and .52, respectively.
 
  Comparable Company Analysis. DLJ analyzed the operating performance of Rite
Aid and Thrifty PayLess relative to six retail drug store companies deemed by
DLJ to be reasonably comparable to Rite Aid and Thrifty PayLess. These
companies are as follows: Walgreen, Revco, CVS, Longs Drug Stores, Eckerd and
Arbor Drugs (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 October 11, 1996.
 
  DLJ analyzed the relative performance and value for Rite Aid and Thrifty
PayLess by comparing certain market trading statistics for Rite Aid and
Thrifty PayLess 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 12 months revenues,
earnings before interest, taxes, depreciation and amortization and LIFO
charges ("EBITDAL") and earnings before interest and taxes ("EBIT") and price
to earnings ratios ("P/E") based on the latest 12 months EPS and estimated
calendar years ending 1997 and 1998 EPS. As of October 11, 1996 this analysis
resulted in (i) a range of 0.3x to 0.8x enterprise value to latest 12 months
revenues for the Comparable Companies compared to 0.5x for Thrifty PayLess at
the Exchange Ratio and 0.8x for Rite Aid; (ii) a range of 5.8x to 12.2x
enterprise value to latest 12 months EBITDAL for the Comparable Companies
compared to 9.3x for Thrifty PayLess at the Exchange Ratio and 9.0x for Rite
Aid, (iii) a range of 8.6x to 15.6x enterprise value to latest 12 months EBIT
for the Comparable Companies compared to 16.1x for Thrifty PayLess and 12.8x
for Rite Aid, (iv) a range of 15.4x to 25.5x P/E based on latest 12 months EPS
for the Comparable Companies
 
                                      24
<PAGE>
 
compared to 32.8x for Thrifty PayLess at the Exchange Ratio and 18.4x for Rite
Aid, and (v) a range of 14.7x to 23.6x and 13.6x to 20.8x estimated P/E based
on 1996 and 1997 calendar year estimates, respectively, for the Comparable
Companies, compared to 31.5x and 21.4x, respectively, for Thrifty PayLess at
the Exchange Ratio and 17.0x and 15.1x, respectively, for Rite Aid. In
addition, DLJ analyzed the implied multiples for Thirty PayLess at the
Exchange Ratio including the Synergies. EPS estimates for Rite Aid, Thrifty
PayLess and the Comparable Companies were based on estimates provided by First
Call Research Direct.
 
  No company utilized in the Comparable Company Analysis is identical to Rite
Aid or Thrifty PayLess. 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 Thrifty
PayLess 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 based upon selected merger
and acquisition transactions in the retail drug store industry. Multiples of
(i) aggregate transaction value (defined as the equity value of the offer plus
book value of total debt and preferred stock less cash) to revenues, EBITDAL
and EBIT and (ii) aggregate purchase price (defined as the equity value of the
offer) to net income and tangible book value were compared with multiples paid
or implied in certain other merger and acquisition transactions involving
retail drug store companies from 1994 through 1996. The comparison included a
total of five transactions. These transactions included: Revco D.S. Inc. and
Big B Inc. (pending); Thrift Drug and Fay's Drug (pending); Rite Aid and Revco
D.S. Inc. (terminated); Rite Aid and Perry Drug Stores (completed); Revco D.S.
Inc. and Hook-SupeRx (completed). This analysis resulted in (i) a range of
0.3x to 0.5x latest 12 months revenue compared to 0.5x for Thrifty PayLess at
the Exchange Ratio, (ii) a range of 8.1x to 10.6x latest 12 months EBITDAL
compared to 9.3x for Thrifty PayLess at the Exchange Ratio, (iii) a range of
13.1x to 19.8x latest 12 months EBIT compared to 16.1x for Thrifty PayLess at
the Exchange Ratio, (iv) a range of 21.8x to 52.7x latest 12 months net income
compared to 32.8x for Thrifty PayLess at the Exchange Ratio, and (v) a range
of 1.9x to 3.9x latest 12 months book value per share compared to 3.8x for
Thrifty PayLess at the Exchange Ratio.
 
  No transaction utilized in the Comparable Transaction Analysis is identical
to 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 Thrifty
PayLess 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.
 
  Relative Contribution Analysis. DLJ analyzed the relative contributions of
Rite Aid and Thrifty PayLess to the revenues, EBITDAL, EBIT and net income of
the combined entity for the 12 months ended June 1996 and the estimated fiscal
year ending February 1997. Based on the latest 12 months Thrifty PayLess'
revenues, EBITDAL, EBIT and, net income represent 46.3%, 34.1%, 30.0%, and
26.7%, respectively, of the combined entity. Based on the estimated fiscal
year ended 1997, Thrifty PayLess' revenues, EBITDAL, EBIT and net income
represent 45.1%, 34.1%, 33.1% and 27.4%, respectively, of the combined entity.
The Rite Aid shares to be issued to the Thrifty PayLess stockholders represent
approximately 31.2% of Rite Aid's outstanding shares pro forma for the Merger.
 
  Premium Analysis. DLJ performed a comparison of the premium represented by
the Exchange Ratio to premiums offered in acquisitions of $1.0 billion to $5.0
billion in size ("Comparable Acquisitions") from January 1, 1993 to the year
to date period ended October 4, 1996. DLJ indicated that for the 38 Comparable
Acquisitions surveyed, the average and median premiums to the market price one
day, one week and one month prior to announcement were 30.5%, 29.7% and 38.0%,
respectively. The Exchange Ratio represented: a 26.9% premium to the trading
price one day prior to announcement, as compared to average premiums for
Comparable Acquisitions of 30.5%, a premium of 27.8% to the trading price one
week prior to the announcement, as compared to average premiums for Comparable
Acquisitions of 29.7% and a 27.6% premium to the trading price one month prior
to the announcement, as compared to average premiums for Comparable
Acquisitions of 38.0%.
 
                                      25
<PAGE>
 
   
  Pro Forma Merger Analysis. DLJ analyzed the pro forma effects on the
earnings per share resulting from the Merger including, without independent
verification, the Synergies as forecasted by the management of Rite Aid
contemplated to result from the Merger with respect to Rite Aid's 12 months
ended June 1, 1996, estimated fiscal year ended February 1997 and projected
fiscal years ending February 1998 and 1999. 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 Thrifty PayLess and prevailing interest rates. The
analysis indicated that, with the benefit of the Synergies, the Merger is
anticipated to be accretive to Rite Aid's stand-alone earnings per share
estimates for the fiscal years ending February 1998 and 1999.     
 
  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 Thrifty PayLess, based upon
financial projections prepared by the respective managements of each company
(although such financial projections for Thrifty PayLess extended only through
its 1997 fiscal year). Unlevered free cash flows were calculated as the after-
tax operating earnings of Rite Aid and Thrifty PayLess, 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 EBITDAL multiples
of 7.0x to 8.0x to the projected unlevered free cash flows of Rite Aid and
Thrifty PayLess, 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 of 10.0% to 12.5% representing an estimated range of the
weighted average cost of capital of Rite Aid and Thrifty PayLess. Based on
this analysis, DLJ calculated per share equity values of Rite Aid ranging from
$32.43 to $44.59 and of Thrifty PayLess ranging from $17.55 to $24.06. DLJ
also compared the per share equity value of Rite Aid to the per share equity
value of Thrifty PayLess including the Synergies.
 
  The summary set forth above does not purport to be a complete description of
the analyses performed by DLJ, but describes, in summary form, the principal
elements of the analyses made by DLJ in arriving at the DLJ Opinion. The
preparation of a fairness opinion involves various determinations as to the
most appropriate and relevant methods of financial analysis and the
application of these methods to the particular circumstances and, therefore,
such an opinion is not readily susceptible to summary description. Each of the
analyses conducted by DLJ was carried out in order to provide a different
perspective on the transaction and add to the total mix of information
available. DLJ did not form a conclusion as to whether any individual
analysis, considered in isolation, supported or failed to support an opinion
as to fairness from a financial point of view. Rather, in reaching its
conclusion, DLJ considered the results of the analyses in light of each other
and ultimately reached its opinion based on the results of the analyses taken
as a whole. DLJ did not place particular reliance or weight on any individual
factor, but instead concluded that its analyses, taken as a whole, supported
its determination. Accordingly, notwithstanding the separate factors
summarized above, DLJ believes that its analyses must be considered as a whole
and that selecting portions of its analysis and the factors considered by it,
without considering all analyses and factors, could create an incomplete or
misleading view of the evaluation process underlying its opinions. In
performing its analyses, DLJ made numerous assumptions with respect to
industry performance, business and economic conditions and other matters. The
analyses performed by DLJ are not necessarily indicative of actual values or
future results, which may be significantly more or less favorable than
suggested by such analyses.
 
  DLJ was selected to render an opinion in connection with the Merger based
upon DLJ's qualifications, expertise and reputation, including the fact that
DLJ, as part of its investment banking business, is regularly engaged in the
valuation of businesses and their securities in connection with mergers and
acquisitions, underwritings, sales and distributions of listed and unlisted
securities, private placements and valuations for corporate and other
purposes.
 
  Pursuant to a letter agreement between Rite Aid and DLJ dated October 11,
1996 (the "DLJ Engagement Letter"), DLJ is entitled to (i) a retainer fee of
$1.0 million payable upon execution of the DLJ Engagement Letter, (ii) a fee
of $250,000 at the time DLJ delivers its opinion to the Rite Aid Board, and
(iii) a transaction fee equal to $7.0 million upon consummation of the Merger.
Any amounts payable pursuant to clauses (i) and (ii) above will be credited
against the transaction fee. Rite Aid has agreed to reimburse DLJ for its out-
of-pocket
 
                                      26
<PAGE>
 
expenses, including reasonable fees and expenses of its counsel, and to
indemnify DLJ for liabilities and expenses arising out of the Merger or the
transactions in connection therewith, including liabilities under federal
securities laws. The terms of the fee arrangement with DLJ, which DLJ and Rite
Aid believe are customary in transactions of this nature, were negotiated at
arm's length between Rite Aid and DLJ and the Rite Aid Board was aware of such
arrangement, including the fact that a significant portion of the aggregate
fee payable to DLJ is contingent upon consummation of the Merger.
 
  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
Thrifty PayLess and/or Rite Aid for its own account and for the account of
customers. Over the past two years, DLJ has (i) lead managed a $200 million
senior notes offering for Rite Aid, (ii) advised Rite Aid in the sale of four
of its non-drug store subsidiaries, and (iii) advised Rite Aid and acted as
dealer manager for Rite Aid with respect to its attempted acquisition of Revco
D.S., Inc. DLJ has received customary compensation for the above-mentioned
services. Over the past two years, DLJ has also (i) co-managed the Thrifty
PayLess IPO and (ii) acted as dealer manager for TPI and Thrifty PayLess in
conjunction with the tender offers for TPI's 11 3/4% Senior Notes due 2003 and
Thrifty PayLess' 11 5/8% Senior Notes due 2006, respectively. DLJ has also
received customary compensation for the above mentioned services. DLJ has also
acted as financial advisor (or in a comparable capacity) in various other
transactions in which GEI and/or LGA have had material interests. In addition,
in connection with the 1992 Thrifty Acquisition, DLJ and its affiliates
acquired certain shares of Thrifty PayLess Common Stock, with respect to which
DLJ and its affiliates currently own less than 6% of the A Common Stock and
less than 1% of the B Common Stock.
 
THRIFTY PAYLESS' REASONS FOR THE MERGER; RECOMMENDATION OF THE THRIFTY PAYLESS
BOARD
 
  On October 13, 1996, the Thrifty PayLess Board, by unanimous vote, approved
the Merger Agreement and the transactions contemplated thereby (including the
Merger) as being in the best interests of Thrifty PayLess and its stockholders
and decided to recommend adoption of the Merger Agreement and the transactions
contemplated thereby to Thrifty PayLess stockholders. In reaching these
conclusions, the Thrifty PayLess Board considered, among other things, the
following factors:
 
  . The value to Thrifty PayLess stockholders of the continuation of Thrifty
    PayLess as an independent entity versus a strategic combination with Rite
    Aid pursuant to the Merger. The Thrifty PayLess Board determined that the
    Merger afforded Thrifty PayLess stockholders the opportunity to invest in
    a larger company with greater financial resources, a stronger balance
    sheet and improved potential for long-term appreciation. In that regard,
    the Thrifty PayLess Board considered information concerning the
    respective businesses, operations, expense structures, assets, financial
    condition, strategies, expansion opportunities and prospects of Thrifty
    PayLess and Rite Aid, the potential contributions of each of Thrifty
    PayLess and Rite Aid to the revenues, operating profit and net profits of
    the combined company, and the potential for cost savings and synergies
    from the Merger in light of Right Aid's plans for the integration of the
    two companies' respective operations and business. The Thrifty Payless
    Board also took into consideration the prior success of Rite Aid's
    management in acquiring and integrating other drug store chains.
 
  . A comparison of the historical market prices and trading information of
    Thrifty PayLess Common Stock and Rite Aid Common Stock. Based on the
    closing market prices of Rite Aid Common Stock on October 11, 1996 (the
    last trading day immediately prior to the public announcement of the
    Merger), the value of the Rite Aid Common Stock that would have been
    received by Thrifty PayLess stockholders in exchange for their Thrifty
    PayLess Common Stock pursuant to the Merger if it had occurred on such
    date would have represented a premium of 26.9% above the then-current
    market price of the B Common Stock. In addition, the Thrifty PayLess
    Board considered the Minimum Price Condition under the Merger Agreement,
    which generally provides that Thrifty PayLess may elect not to consummate
    the Merger if the average market price of Rite Aid Common Stock falls
    below $30.75 during a specified period (except under certain limited
    circumstances, in which case such average may be less than $30.75 but
    must be at least $29.00). If the market price of Rite Aid Common Stock
    were $30.75 as of the
 
                                      27
<PAGE>
 
       
    Effective Time, Thrifty PayLess stockholders would receive, for each
    share of Thrifty PayLess Common Stock, Rite Aid Common Stock with a value
    of $19.99, which amount exceeds the highest closing market price as
    reported on the NYSE Composite Tape ($18.875 per share) that Thrifty
    PayLess B Common Stock achieved at any time following the date of the
    Thrifty PayLess IPO and before the date of the first public announcement
    of the Merger.     
     
  . The terms and conditions of the Merger Agreement and related matters,
    including the Exchange Ratio, closing conditions, termination rights,
    termination fees, the cash-out of Thrifty PayLess Stock Options and
    severance arrangements for existing Thrifty PayLess employees designed to
    ensure a smooth transition in connection with the Merger, all of which
    were the product of arms' length negotiations in which Thrifty PayLess
    was assisted by its financial advisor, Goldman Sachs, and its counsel,
    Irell & Manella LLP.     
 
  . The terms and conditions of the GEI/Kmart Stockholder Agreements,
    pursuant to which Thrifty PayLess' two largest stockholders, GEI and
    Kmart, agreed to vote their respective shares of Thrifty PayLess Common
    Stock in favor of the adoption of the Merger Agreement, thereby
    significantly enhancing the likelihood of the consummation of the Merger.
 
  . The financial analyses presented by Goldman Sachs, as well as the written
    opinion of Goldman Sachs to the effect that, based upon and subject to
    various considerations set forth in such opinion, as of October 13, 1996,
    the Exchange Ratio pursuant to the Merger Agreement is fair to the
    holders of Thrifty PayLess Common Stock. See "--Opinion of Goldman
    Sachs."
 
  . The absence of any overlap between the geographic markets of Thrifty
    PayLess and Rite Aid, as a result of which the Merger is less likely to
    be impeded by antitrust issues than would be the case if there were
    significant geographic overlap.
 
  . The advantages to Thrifty PayLess stockholders, who have not received any
    dividends on their shares of Thrifty PayLess Common Stock during the last
    two fiscal years, of receiving cash dividends at Rite Aid's historical
    annual rate of $0.74 per share. In this connection, the Thrifty PayLess
    Board of Directors considered that there could be no assurance as to the
    timing or amount of any future dividends by Rite Aid.
 
  . The fact that the Merger is conditioned upon the receipt of an opinion of
    counsel that the Merger will be treated for federal income tax purposes
    as a reorganization within the meaning of Section 368(a) of the Code and
    that no gain or loss will be recognized by the stockholders of Thrifty
    PayLess upon their exchange of Thrifty PayLess Common Stock for Rite Aid
    Common Stock under Section 354 of the Code (except with respect to any
    cash received in lieu of fractional shares).
 
  . Various risks inherent in the Merger and the transactions contemplated
    thereby, including the following: (i) potential difficulties that could
    arise in connection with the integration of the operations of Rite Aid
    and Thrifty PayLess, particularly in light of the geographic separation
    of the two chains, Rite Aid's plans to change the name of all Thrifty and
    PayLess drug stores to Rite Aid, the generally larger size of Thrifty
    PayLess drug stores and the generally greater mix of non-pharmacy
    merchandise at Thrifty PayLess drug stores; (ii) substantial expenses and
    charges against Rite Aid's earnings that are expected to arise in
    connection with the Merger and the integration of the two chains; (iii)
    the fact that the Merger is to be accounted for as a purchase, requiring
    amortization of goodwill and other intangible assets; and (iv) the
    possibility that the market price of Rite Aid Common Stock may be
    adversely affected by the Merger. The Thrifty PayLess Board determined
    that these risks were substantially outweighed by the potential
    advantages of the Merger.
 
The foregoing discussion of the information and factors considered by the
Thrifty PayLess Board is not intended to be exhaustive, but includes all
material factors considered by the Board. In reaching its determination to
approve the Merger Agreement and the transactions contemplated thereby, the
Thrifty PayLess Board did not assign any relative or specific weights to the
various factors considered by it nor did it specifically characterize any
factor as positive or negative (except as described above), and individual
directors may have given different weights to different factors and may have
viewed certain factors more positively or negatively than others.

  FOR THE REASONS DESCRIBED ABOVE, THE THRIFTY PAYLESS BOARD UNANIMOUSLY
RECOMMENDS THAT THE HOLDERS OF THRIFTY PAYLESS COMMON STOCK VOTE "FOR"
APPROVAL OF THE MERGER AGREEMENT.
 
OPINION OF GOLDMAN SACHS
 
  On October 13, 1996, Goldman Sachs delivered its written opinion to the
Thrifty PayLess Board that, as of the date of such opinion, the Exchange Ratio
pursuant to the Merger Agreement is fair to the holders of Thrifty PayLess
Common Stock.
 
  THE FULL TEXT OF THE WRITTEN OPINION OF GOLDMAN SACHS, DATED OCTOBER 13,
1996, WHICH SETS FORTH ASSUMPTIONS MADE, MATTERS CONSIDERED AND LIMITATIONS ON
THE REVIEW UNDERTAKEN IN CONNECTION WITH THE OPINION, IS ATTACHED HERETO AS
ANNEX C TO THIS JOINT PROXY STATEMENT/PROSPECTUS AND IS INCORPORATED HEREIN BY
REFERENCE. STOCKHOLDERS OF THRIFTY PAYLESS ARE URGED TO, AND SHOULD, READ SUCH
OPINION IN ITS ENTIRETY.
 
  In connection with its opinion, Goldman Sachs reviewed, among other things,
(i) the Merger Agreement; (ii) Thrifty PayLess' Registration Statement on Form
S-1 dated April 15, 1996; (iii) audited financial statements of Thrifty
PayLess for the three fiscal years ended on October 1, 1995; (iv) Annual
Reports to Stockholders and Annual Reports on Form 10-K of Rite Aid for the
five fiscal years ended March 2, 1996; (v) certain interim reports to
stockholders and Quarterly Reports on Form 10-Q of Thrifty PayLess and Rite
Aid; (vi) certain other communications from Thrifty PayLess and Rite Aid to
their respective stockholders; and (vii) certain internal financial analyses
and forecasts for Thrifty PayLess and Rite Aid prepared by their respective
managements. Goldman Sachs also held discussions with members of the senior
management of Thrifty PayLess and Rite Aid regarding the past and current
business operations, financial condition and future prospects of their
respective companies and with respect to the strategic and operational
benefits projected to be derived from the Merger, including certain cost
savings and operational synergies expected to be realized. In addition,
Goldman Sachs reviewed the reported price and trading activity for the Thrifty
PayLess Common Stock and Rite Aid Common Stock, compared certain financial and
stock market information for Thrifty PayLess and Rite Aid with similar
information for certain other companies the securities of which are publicly
traded, reviewed the financial terms of certain recent business combinations
in the drug store industry specifically and in other industries generally and
performed such other studies and analyses as it considered appropriate.
 
  Goldman Sachs relied without independent verification upon the accuracy and
completeness of all of the financial and other information reviewed by it for
purposes of its opinion. In addition, Goldman Sachs has not made an
independent evaluation or appraisal of the assets and liabilities of Thrifty
PayLess or Rite Aid or any of their subsidiaries and Goldman Sachs has not
been furnished with any such evaluation or appraisal.
 
  The following is a summary of certain of the financial analyses used by
Goldman Sachs in connection with providing its written opinion to Thrifty
PayLess' Board of Directors on October 13, 1996.
 
  Selected Companies Analysis. Goldman Sachs reviewed and compared certain
financial information relating to Thrifty PayLess and Rite Aid to
corresponding financial information, ratios and public market multiples for
six publicly traded corporations, including Rite Aid: Arbor Drugs, Inc.,
Eckerd Corp., Longs Drug Stores Corp., Revco D.S., Inc., Rite Aid and Walgreen
Co. (the "Selected Companies"). Goldman Sachs calculated and compared various
financial multiples and ratios. The multiples of Thrifty PayLess and Rite Aid
were calculated using a price of $18.38 per share of Thrifty PayLess Common
Stock and $35.63 per share of Rite Aid Common Stock, the closing price of such
shares on October 10, 1996, and the multiples of the Selected Companies were
calculated using closing market prices for such companies on October 10, 1996.
Except as set forth below, the multiples and ratios for Thrifty PayLess, Rite
Aid and each of the Selected Companies were based on the most recent publicly
available information. With respect to the Selected Companies, Goldman Sachs
considered levered market capitalization (i.e., market value of common equity
plus estimated market value of debt and preferred stock less cash) as a
multiple of the latest twelve months ("LTM") EBITDAL, as a multiple of
estimated calendar year 1996 EBITDAL (based on Goldman Sachs' research
estimates as of October 6, 1996)
 
                                      29
<PAGE>
 
and as a multiple of LTM EBIT. Goldman Sachs' analyses of the Selected
Companies indicated levered multiples of LTM EBITDAL, which ranged from a low
of 5.7x to a high of 12.5x, with a mean of 8.8x and a median of 8.6x,
estimated calendar year 1996 EBITDAL, which ranged from a low of 5.4x to a
high of 11.2x, with a mean of 8.2x and a median of 8.0x, and LTM EBIT, which
ranged from a low of 8.6x to a high of 15.6x, with a mean of 12.7x and a
median of 12.6x, compared to levered multiples of 8.0x, 7.4x and 13.8x,
respectively, for Thrifty PayLess, and levered multiples of 8.9x, 8.1x and
12.7x, respectively, for Rite Aid. Goldman Sachs also considered for the
Selected Companies LTM and estimated calendar year 1996 and 1997
price/earnings ratios (based on Institutional Broker Estimate System ("IBES")
estimates as of October 6, 1996), which for the Selected Companies ranged from
a low of 15.2x to a high of 25.4x, with a mean of 20.4x and a median of 20.9x,
for LTM, a low of 14.6x to a high of 23.1x, with a mean of 18.9x and a median
of 18.9x, for estimated calendar year 1996, and from a low of 13.5x to a high
of 20.6x, with a mean of 16.7x and a median of 16.1x, for estimated calendar
year 1997, compared to 18.3x, 16.6x and 14.8x, respectively, for Rite Aid, and
estimated calendar year 1996 and 1997 of 21.4x and 16.0x, respectively, for
Thrifty PayLess (LTM information is not meaningful for Thrifty PayLess); LTM
EBITDAL margins for the Selected Companies, LTM EBIT margins and LTM net
income margins, which ranged from a low of 5.2% to a high of 8.7%, with a mean
of 6.7% and a median of 6.6%, a low of 3.5% to a high of 6.0%, with a mean of
4.6% and a median of 4.6%, and a low of 1.7% to a high of 3.2%, with a mean of
2.5% and a median of 2.6%, respectively, compared to LTM, EBITDAL and EBIT
margins of 5.2%, and 3.0%, respectively, for Thrifty PayLess (LTM net income
margin information is not meaningful for Thrifty PayLess), and 8.7%, 6.0% and
3.0%, respectively, for Rite Aid. IBES is a data service which monitors and
publishes a compilation of earnings estimates produced by selected research
analysts on companies of interest to investors.
 
  Selected Transactions Analysis. Goldman Sachs analyzed certain information
relating to 18 selected transactions in the drug store industry since April
1988 including three pending transactions and one transaction which was
terminated (the "Selected Transactions"). The comparisons to Thrifty PayLess
referred to below assume that holders of Thrifty PayLess Common Stock receive
in the Merger $23.00 in Rite Aid Common Stock for each share of Thrifty
PayLess Common Stock (which is lower than the $23.32 to be received by holders
of Thrifty PayLess Common Stock based on the closing price per share of Rite
Aid Common Stock of $35.875 on October 11, 1996). Such analysis indicated that
for the Selected Transactions levered consideration as a multiple of (i) LTM
sales ranged from a low of 0.27x to a high of 1.00x, with a mean of 0.45x and
a median of 0.38x, as compared to 0.48x for Thrifty PayLess (based on Thrifty
PayLess' LTM as of June 30, 1996) and (ii) LTM EBIT ranged from a low of 6.6x
to a high of 167.5x, with a mean of 12.9x and a median of 13.0x, as compared
to 16.0x for Thrifty PayLess (based on Thrifty PayLess' LTM as of June 30,
1996). Such analysis also indicated that for the Selected Transactions
aggregate consideration as a multiple of LTM EPS/net income ranged from a low
of 13.1x to a high of 44.6x, with a mean of 24.9x and a median of 24.5x, as
compared to 35.9x for Thrifty PayLess (based on estimated calendar year EPS
for 1996). For purposes of the Selected Transactions Analysis the mean and
median were calculated excluding the high and low transactions.
 
  Pro Forma Accretion/Dilution Analysis. Goldman Sachs analyzed the
accretive/dilutive impact of the Merger, both excluding synergies and on a pro
forma basis for synergies, with respect to Rite Aid's projected 1998 and 1999
EPS. This analysis was based on a number of assumptions, including, among
other things, the cost of integration, estimated amounts and timing of the
synergies and the projected financial performance of Rite Aid and Thrifty
PayLess. From the standpoint of stockholders of Thrifty PayLess, the analyses
indicated that (i) projected earnings for 1998 would increase from $1.19 per
share, on a standalone basis, to $1.29 per share, after giving effect to the
Merger, assuming no synergies are realized, and to $1.50 per share, after
giving effect to the Merger, assuming $65 million in pre-tax profit
improvements are realized and (ii) projected dividends paid for 1998 (based on
the calendarized dividend of Rite Aid's most recent quarter) would increase
from $0.00 per share, on a standalone basis, to $0.48 per share, after giving
effect to the Merger.
 
  Contribution Analysis. Goldman Sachs reviewed certain historical and
estimated future operating and financial information (including, among other
things, sales, EBITDAL, EBIT, net income and number of stores) for Thrifty
PayLess and Rite Aid (based on their respective managements' estimates) and
the pro forma
 
                                      30
<PAGE>
 
combined entity resulting from the Merger (such estimates compare Thrifty
PayLess' fiscal years ending in September with Rite Aid's fiscal years ending
the following February). The analysis indicated that (i) the Thrifty PayLess
stockholders would receive 32.0% of the outstanding common equity of the
combined entity, (ii) using a price of $18.38 per share of Thrifty PayLess
Common Stock and $35.875 per share of Rite Aid Common Stock, the closing price
of such shares on October 11, 1996, the Thrifty PayLess stockholders would
contribute 26.6% of the equity market capitalization and 31.5% of the levered
market capitalization of the combined entity, and (iii) assuming that a price
per share of Thrifty PayLess Common Stock was $22.00, $23.00 and $24.00, the
Thrifty PayLess stockholders would contribute 30.3%, 31.3% and 32.2%,
respectively, of the equity market capitalization and 33.8%, 34.4% and 35.0%,
respectively, of the levered market capitalization. Goldman Sachs analyzed the
relative contribution of Thrifty PayLess and Rite Aid to the combined entity
based on actual 1996 and estimated year 1997. This analysis indicated that (a)
in 1996 Thrifty PayLess would contribute 46.1% to combined sales, 30.7% to
combined EBITDAL, 25.6% to combined EBIT and a negative 16.8% to combined net
income and (b) in estimated calendar year 1997 Thrifty PayLess would
contribute 44.5% to combined sales, 32.7% to combined EBITDAL, 31.4% to
combined EBIT and 14.2% to combined net income. This analysis indicated that
Thrifty PayLess would contribute 27.3% of the number of stores (based on
Thrifty PayLess' number of stores as of June 1996 and Rite Aid's number of
stores as of August 1996) to the combined entity.
 
  Analysis at Various Prices. Goldman Sachs prepared a financial analysis of
the Merger and calculated various financial multiples assuming (i) that
holders of Thrifty PayLess Common Stock receive in the Merger $18.00, $19.00,
$20.00, $21.00, $22.00, $23.00, $24.00, $25.00 and $26.00 in Rite Aid Common
Stock for each share of Thrifty PayLess Common Stock and (ii) the following
corresponding amounts of enterprise value (equity consideration (assuming 59.5
million shares of Thrifty PayLess Common Stock outstanding), plus debt and
preferred stock outstanding minus cash and cash equivalents): $1,950.1
million, $2,012.0 million, $2,073.9 million, $2,135.9 million, $2,197.8
million, $2,259.7 million, $2,321.6 million, $2,383.6 million and $2,445.5
million. Since the value of the Rite Aid Common Stock to be received in the
Merger for each share of Thrifty PayLess Common Stock will fluctuate with
increases or decreases in the market value of the Rite Aid Common Stock,
Goldman Sachs performed this analysis assuming the foregoing range. Goldman
Sachs calculated multiples of the aggregate enterprise value to: (i) sales,
(ii) EBITDAL, (iii) EBIT, and (iv) primary EPS. This analysis indicated that
the multiples of LTM sales (based on Thrifty PayLess' LTM as of June 1996)
ranged from a low of 0.41x to a high of 0.52x; estimated 1996 sales ranged
from a low of 0.41x to a high of 0.51x; and estimated 1997 sales ranged from a
low of 0.38x to a high of 0.48x. This analysis indicated that the multiples of
(A) LTM EBITDAL (based on Thrifty PayLess' LTM as of June 1996) ranged from a
low of 8.0x to a high of 10.0x; (B) estimated 1996 EBITDAL ranged from a low
of 7.6x to a high of 9.5x; and (C) estimated 1997 EBITDAL ranged from a low of
6.8x to a high of 8.6x. This analysis indicated that the multiples of (1) LTM
EBIT (based on Thrifty PayLess' LTM as of June 1996) ranged from a low of
13.8x to a high of 17.3x; (2) estimated 1996 EBIT ranged from a low of 11.6x
to a high of 14.6x; and (3) estimated 1997 EBIT ranged from a low of 10.1x to
a high of 12.6x. This analysis indicated that the multiples of (x) estimated
1996 EPS ranged from a low of 28.1x to a high of 40.6x and (y) estimated 1997
EPS ranged from a low of 16.4x to a high of 23.6x. This analysis also
indicated that the premium over LTM book value (based on Thrifty PayLess' LTM
as of June 1996) ranged from a low of 189.7% to a high of 321.8%.
 
  Historical Stock Trading Analysis. Goldman Sachs reviewed the historical
trading prices and volumes for the Thrifty PayLess Common Stock and the Rite
Aid Common Stock. Such analyses indicated that the price per share of Thrifty
PayLess Common Stock to be paid pursuant to the Merger Agreement represented a
premium of 26.9% based on the closing price per share of Thrifty PayLess
Common Stock and Rite Aid Common Stock on October 11, 1996 of $18.375 and
$35.875, respectively. In addition, Goldman Sachs reviewed (a) the weighted
average trading price for Thrifty PayLess Common Stock for the latest three
months and since April 16, 1996 (the date of the Thrifty PayLess IPO) and (b)
the weighted average trading price for Rite Aid Common Stock for the latest
three months, the latest six months and the LTM. The weighted average trading
price for Thrifty PayLess Common Stock was $16.24 and $15.00, respectively,
and the weighted average trading price for Rite Aid Common Stock was $32.97,
$30.93, and $31.33, respectively.

  The preparation of a fairness opinion is a complex process and is not
necessarily susceptible to partial analysis or summary description. Selecting
portions of the analyses or of the summary set forth above, without
considering the analyses as a whole, could create an incomplete view of the
processes underlying Goldman Sachs' opinion. In arriving at its fairness
determination, Goldman Sachs considered the results of all such analyses. No
company or transaction used in the above analyses as a comparison is directly
comparable to Thrifty PayLess or Rite Aid or the contemplated transaction. The
analyses were prepared solely for purposes of Goldman Sachs' providing its
opinion to the Thrifty PayLess Board as to the fairness to the holders of
Thrifty PayLess Common Stock of the Exchange Ratio pursuant to the Merger
Agreement and do not purport to be appraisals or necessarily reflect the
prices at which businesses or securities actually may be sold. Analyses based
upon forecasts of future results are not necessarily indicative of actual
future results, which may be significantly more or less favorable than
suggested by such analyses. Because such analyses are inherently subject to
uncertainty, being based upon numerous factors or events beyond the control of
the parties or their respective advisors, none of Thrifty PayLess, Rite Aid,
Goldman Sachs or any other person assumes responsibility if future results are
materially different from those forecast.     
 
  As described above, Goldman Sachs' opinion to the Thrifty PayLess Board was
one of many factors taken into consideration by the Thrifty PayLess Board in
making its determination to approve the Merger Agreement. The foregoing
summary does not purport to be a complete description of the analysis
performed by Goldman Sachs and is qualified by reference to the written
opinion of Goldman Sachs set forth in Annex C hereto.
 
  Goldman Sachs, 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 biddings,
secondary distributions of listed and unlisted securities, private placements
and valuations for estate, corporate and other purposes. Thrifty PayLess
selected Goldman Sachs as its financial advisor because it is a nationally
recognized investment banking firm that has substantial experience in
transactions similar to the Merger. Goldman Sachs is familiar with Thrifty
PayLess having provided certain investment banking services to Thrifty PayLess
from time to time, including having acted as the co-managing underwriter of
the Thrifty PayLess IPO in April 1996 and having acted as its financial
advisor in connection with, and having participated in certain of the
negotiations leading to, the Merger Agreement. Goldman Sachs has also provided
certain investment banking services to Rite Aid from time to time, including
participation in its commercial paper program, and may provide services to
Rite Aid in the future.
 
  Goldman Sachs 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 Thrifty PayLess and/or Rite Aid for its own account and for the
account of customers. As of October 13, 1996 (the date of its opinion) Goldman
Sachs had a short position of 102,852 shares of Rite Aid Common Stock, a long
position of $7,159,000 of 0% convertible bonds of Rite Aid, a long position of
$15,000,000 of commercial paper of Rite Aid, and a long position of
$20,000,000 of the bank debt of Thrifty PayLess.
   
  Pursuant to a letter agreement dated October 11, 1996 (the "Goldman Sachs
Engagement Letter"), Thrifty PayLess engaged Goldman Sachs to act as its
financial advisor in connection with a proposed strategic transaction between
Thrifty PayLess and Rite Aid. Pursuant to the terms of the Goldman Sachs
Engagement Letter, Thrifty PayLess has agreed to pay Goldman Sachs upon the
purchase of 50% or more of the outstanding Thrifty PayLess Common Stock in one
or a series of transactions, including, but not limited to, private or open
market purchases of stock, a tender offer, a merger or an acquisition by Rite
Aid of the Thrifty PayLess Common Stock, a transaction fee of $5.0 million.
The transaction fee will be paid in cash upon consummation of the Merger.
Thrifty PayLess has agreed to reimburse Goldman Sachs for reasonable out-of-
pocket expenses, including fees and disbursements for Goldman Sachs'
attorneys, plus any sales, use or similar taxes (including additions to such
taxes, if any) arising in connection with such matters referred to in the
Goldman Sachs Engagement Letter. Thrifty PayLess has agreed to indemnify
Goldman Sachs against certain liabilities, including certain liabilities under
the federal securities laws.     
 
 
                                      32
<PAGE>
 
CERTAIN FEDERAL INCOME TAX CONSEQUENCES
   
  The following is a summary of material federal income tax consequences of
the Merger based on current law. Neither Rite Aid nor Thrifty PayLess has
requested or will request any ruling from the IRS as to the United States
federal income tax consequences of the Merger. Future legislative, judicial or
administrative changes or interpretations, which may be retroactive, could
alter or modify the statements set forth herein. This summary may not apply to
certain classes of taxpayers, including, without limitation, insurance
companies, tax-exempt organizations, financial institutions, dealers in
securities, nonresident aliens, foreign corporations, persons who acquired
shares of Thrifty PayLess Common Stock pursuant to the exercise of employee
stock options or rights or otherwise as compensation and persons who hold
shares of Thrifty PayLess Common Stock in a hedging transaction or as part of
a straddle or conversion transaction. Also, the summary does not address
state, local or foreign tax consequences of the Merger. Consequently, each
holder of Thrifty PayLess Common Stock (a "Holder") should consult such
Holder's own tax advisor as to the specific tax consequences of the Merger to
such Holder.     
 
  The Merger is intended to be treated as a "reorganization" within the
meaning of Section 368(a) of the Code. Accordingly, for federal income tax
purposes, no income, gain or loss will be recognized by either Rite Aid or
Thrifty PayLess as a result of the Merger and Holders who exchange shares of
Thrifty PayLess Common Stock for shares of Rite Aid Common Stock pursuant to
the Merger will be treated as follows: (i) no income, gain or loss will be
recognized by a Holder with respect to the receipt of Rite Aid Common Stock;
(ii) the aggregate adjusted tax basis of shares of Rite Aid Common Stock
(including a fractional share interest in Rite Aid Common Stock deemed
received and redeemed as described below) received by a Holder will be the
same as the aggregate adjusted tax basis of the shares of Thrifty PayLess
Common Stock exchanged therefor; (iii) the holding period of shares of Rite
Aid Common Stock (including the holding period of a fractional share interest
in Rite Aid Common Stock deemed received and redeemed as described in (iv)
below) received by a Holder will include the holding period of the Thrifty
PayLess Common Stock exchanged therefor, provided that such shares of Thrifty
PayLess Common Stock are held as capital assets at the Effective Time; and
(iv) a Holder of Thrifty PayLess Common Stock who receives cash in lieu of a
fractional share interest in Rite Aid Common Stock will be treated as having
received such fractional share interest and then as having received the cash
in redemption of such fractional share interest. In general, a Holder of
Dissenting Thrifty PayLess Shares receiving solely cash pursuant to the
exercise of appraisal rights will recognize gain or loss equal to the
difference, if any, between the cash received and the dissenting Holder's tax
basis in the Thrifty PayLess Common Stock.
 
  It is a condition to the consummation of the Merger that Thrifty PayLess and
Rite Aid receive an opinion of Jones Day, counsel to Rite Aid, or Irell &
Manella LLP, counsel to Thrifty PayLess, to the effect that the Merger will be
treated for federal income tax purposes as a reorganization within the meaning
of Section 368(a) of the Code and that Thrifty PayLess and Rite Aid will each
be a party to that reorganization within the meaning of Section 368(b) of the
Code and that no gain or loss will be recognized by the stockholders of
Thrifty PayLess upon their exchange of Thrifty PayLess Common Stock for Rite
Aid Common Stock under Section 354 of the Code (except to the extent such
stockholder receives cash in lieu of fractional shares). The opinion of Jones
Day or Irell & Manella LLP referred to in this paragraph will be based upon
certain facts, assumptions and representations and/or covenants, including
those contained in certificates of officers of Rite Aid, Thrifty PayLess and,
possibly, others. If such opinion is not received, the Merger will not be
consummated unless the condition requiring their receipt is waived. Rite Aid
and Thrifty PayLess currently anticipate that such opinion will be delivered
and that neither Rite Aid nor Thrifty PayLess will waive the conditions
requiring receipt of such opinions. Such opinions will not be binding upon the
IRS and no assurance can be given that the IRS will not take a contrary
position.
 
INTERESTS OF CERTAIN PERSONS AND EMPLOYEE MATTERS
 
  In considering the recommendation of the Thrifty PayLess Board with respect
to the Merger, stockholders of Thrifty PayLess should be aware that certain
members of the management of Thrifty PayLess and of the Thrifty PayLess Board
have certain interests in the Merger that are in addition to the interests of
stockholders of
 
                                      33
<PAGE>
 
Thrifty PayLess generally. The Thrifty PayLess Board was aware of these
interests and considered them, among other matters, in approving the Merger
Agreement and the transactions contemplated thereby.
   
  LGA Investment Banking Fee. Pursuant to a Management Services Agreement
between TPI and LGA (the "Management Services Agreement"), LGA is entitled to
receive reasonable and customary fees and reasonable expenses from time to
time for providing financial advisory and investment banking services to
Thrifty PayLess in connection with major financial transactions (the
"Investment Services"). Upon consummation of the Merger, LGA will be paid a
fee of $12.5 million, plus reasonable expenses, in consideration of Investment
Services provided by it in connection with the Merger. Leonard I. Green,
Jonathan D. Sokoloff and Jennifer Holden Dunbar (or entities controlled by
them) are general partners of LGA as well as members of the Thrifty PayLess
Board. Pursuant to its terms, the Management Services Agreement will terminate
upon the effectiveness of the Merger.     
   
  Directorship. In accordance with the terms of the Merger Agreement and the
request of Thrifty PayLess, Rite Aid will take such action as may be required
so that Leonard I. Green, Thrifty PayLess' Chairman of the Board, will be
elected as of the Effective Time as a member of the Rite Aid Board in the
class of members whose term expires at Rite Aid's 1999 annual meeting of
stockholders.     
   
  Severance Arrangements. Pursuant to the Merger Agreement, Rite Aid agreed to
extend certain severance arrangements to employees of Thrifty PayLess and its
subsidiaries (the "Severance Plan"). As of the Effective Time, the Severance
Plan will apply to employees of Thrifty PayLess and its subsidiaries specified
below who are terminated at the Effective Time or who continue to be employed
following the Effective Time. Payments will be made to each eligible employee
whose employment with Rite Aid or any of its subsidiaries is terminated by
Rite Aid or such subsidiary without cause (as defined) or who terminates such
employment for good reason (as defined), in either case (i) without being
offered a position with Rite Aid or any of its subsidiaries at substantially
comparable responsibility or compensation and (ii) within 24 months of the
Effective Time. The Severance Plan will provide for unmitigated severance
payments, payable in a lump sum payment. The categories of executives
specified below (collectively, the "Covered Executives") will be entitled to
severance benefits equal to the applicable multiple specified below multiplied
by their total salary plus "On Plan/Target" bonus for Thrifty PayLess' 1996
fiscal year (subject, except in the case of Thrifty PayLess' Chief Executive
Officer and Chief Financial Officer, to certain limitations under the Code
relating to payments that would otherwise be subject to excise taxes as
described below):

For purposes of the foregoing, (i) "Group A" means current or previously
board-approved Senior Vice Presidents as of October 13, 1996, as well as three
additional officers specified in the Merger Agreement and (ii) "Group B" means
all Vice Presidents as of October 13, 1996. In addition, a third group of
employees consisting of group vice presidents and certain department heads
will be entitled to certain severance benefits. All other Thrifty PayLess
employees working at Thrifty PayLess' headquarters in Wilsonville, Oregon who
will be displaced as a result of the Merger will be entitled to severance
benefits equal to six months' pay if their tenure is more than two years or
six weeks' pay if their tenure is less than two years. Eligible employees
under the Severance Plan will also be entitled to (i) the continuation of
health insurance for the severance period or until covered by a new employer's
plan, whichever occurs first, (ii) company contributions under the TPI Profit
Sharing Plan for the year ended December 31, 1996, and (iii) outplacement
services to be provided by Rite Aid. The Chief Executive Officer and Chief
Financial Officer of Thrifty PayLess will also be entitled to retain the cars
provided to them by Thrifty PayLess without payment to either Rite Aid or
Thrifty PayLess. In addition, in the event that any payment or benefit to or
for the benefit of Thrifty PayLess' Chief Executive Officer or Chief

Financial Officer paid or payable or distributed or distributable pursuant to
the terms of the Merger Agreement or otherwise would be subject to the excise
tax imposed by Section 4999 of the Code or any interest or penalties are
incurred by either such officer with respect to such excise tax (such excise
tax, together with any such interest and penalties, are hereinafter
collectively referred to as the "Excise Tax"), then, subject to certain
limitations, Rite Aid shall make a cash gross-up payment to such officer in an
amount sufficient to place such officer in the same position as he would have
been in if Section 4999 were not in the Code and shall otherwise fully
indemnify such officer with respect to any liability incurred as a result of
such Excise Tax and the payments referred to in this paragraph. For federal
income tax purposes, Rite Aid may be unable to claim an expense deduction for
certain portions of such payments.     
 
  As of the Effective Time, it is anticipated that the foregoing arrangements
will supersede existing severance arrangements (to the extent less favorable
to the employee than those set forth above) with certain executive officers of
Thrifty PayLess, consisting of Gordon D. Barker, David R. Jessick, Barbara R.
Crane and Willard E. Wilson, which arrangements generally provide for
severance benefits upon certain termination events consisting of one year's
salary and on-plan bonus, subject to mitigation by the employee (plus, in the
case of Messrs. Barker and Jessick, an additional one year's salary and on-
plan bonus if termination occurs after certain change-in-control events, as
defined therein).
 
  Pursuant to the terms of a severance agreement entered into between Thrifty
PayLess and Marty W. Smith, the Chief Executive Officer of Bi-Mart, which is
expected to remain in effect following the Merger, in the event that Mr.
Smith's employment with Bi-Mart is terminated other than for cause (as
defined), Mr. Smith will be paid each month, for up to 12 months, his then-
current monthly base salary as severance. If any such termination occurs
within a two-year period following a change of control (as defined), the
period during which such payments are required to be made is extended from 12
to 24 months. The severance benefits will be reduced to the extent of
compensation received from alternative sources of employment (and the employee
is required to seek such employment).
       
  Treatment of Stock Options. Pursuant to the Merger Agreement, each
outstanding Thrifty PayLess Stock Option, including those issued to officers
and directors of Thrifty PayLess, will be converted automatically into a right
to receive an amount of cash equal to (i) 65% of the Rite Aid Share Price,
minus the exercise price per share under the applicable Thrifty PayLess Stock
Option, times (ii) the number of shares of Thrifty PayLess Common Stock
purchasable upon exercise of such Thrifty PayLess Stock Option. As of the
Thrifty PayLess Record Date, the directors and executive officers of Thrifty
PayLess held options to acquire 1,584,040 shares of Thrifty PayLess Common
Stock with exercise prices ranging between $1.67 and $14.17 per share.
 
  A substantial number of such options were granted under the Thrifty PayLess
1994 Management Equity Plan (the "TP Equity Plan"), which became effective
October 19, 1994. The TP Equity Plan provides for the sale to key employees of
Thrifty PayLess of shares of Thrifty PayLess Common Stock and for the grant to
such key employees of options to purchase such shares, with a purchase price
or exercise price, as the case may be, based on the market price of such stock
on the date of sale or grant. A maximum of 3,600,000 shares of A Common Stock
and 7,200,000 shares of B Common Stock are available for issuance under the TP
Equity Plan. The TP Equity Plan is administered by the Compensation Committee
of the Thrifty PayLess Board and has a term of ten years.
 
  Purchases of shares of Thrifty PayLess Common Stock under such plan are made
pursuant to a Management Subscription and Stockholders Agreement, which
provides for payment to be made by means of a combination of cash, recourse
promissory notes and non-recourse promissory notes as determined by Thrifty
PayLess. The promissory notes are secured by a pledge of all of the shares so
purchased by the individual, are due five years from the date of issuance and
bear interest at the rate of 8% per annum. They also contain provisions
requiring principal and interest payments out of bonuses received by the
individual.
 
  Grants of stock options under the TP Equity Plan are made pursuant to a
Stock Option and Stockholders Agreement, which generally provides that the
options vest in installments of 20% per annum over a five-year
 
                                      35
<PAGE>
 
period from the date of grant (although the Thrifty PayLess Compensation
Committee may set different vesting periods). Options granted under the TP
Equity Plan may be designated as incentive stock options ("ISOs") within the
meaning of Section 422 of the Code or as options that do not so qualify
("NSOs"). No ISOs may be granted to any person who owns more than 10% of the
total combined voting power of all classes of Thrifty PayLess' capital stock,
unless the exercise price thereof is at least 110% of the fair market value of
the underlying common stock as of the grant date and such option has a term of
not more than five years. In addition, no ISOs may be issued with an exercise
price of less than 100% of the fair market value of the underlying common
stock as of the grant date or with a term of more than ten years.
   
  Options granted to directors of Thrifty PayLess were issued pursuant to
Thrifty PayLess' Non-Employee Director Stock Option Plan, which became
effective upon consummation of the Thrifty PayLess IPO. Pursuant to such plan,
(i) effective upon consummation of the Thrifty PayLess IPO, each of Richard J.
Lynch, Jr. and Frank G. Felicella received options to acquire 30,000 shares of
B Common Stock, subject to vesting, which options have an exercise price of
$14.00 per share, (ii) on the date of each of Thrifty PayLess' annual
stockholder meetings after January 1, 1997 at which non-management directors
are elected to the Thrifty PayLess Board, each such non-management director
will receive options to acquire 10,000 shares of B Common Stock, subject to
vesting, which options will have an exercise price equal to the market price
of the B Common Stock (as defined in such plan) on the date such options are
granted, and (iii) any non-management director who is first elected or
appointed to the Thrifty PayLess Board after January 1, 1997 other than at an
annual meeting of stockholders will, upon such election or appointment,
receive options to acquire 10,000 shares of B Common Stock, subject to
vesting, which options will have an exercise price equal to the market price
of the B Common Stock on the date such options are granted. Vesting of such
options accelerates upon a change of control of Thrifty PayLess (as defined in
such plan).     
 
  The Merger Agreement provides that, as of the Effective Time, the TP Equity
Plan, the Thrifty PayLess Non-Employee Director Stock Option Plan and all
other management equity plans of Thrifty PayLess (the "Thrifty PayLess 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 Thrifty PayLess or any of its
subsidiaries will be deleted (except as otherwise described below under "--Bi-
Mart Options"). Furthermore, Thrifty PayLess will take all actions necessary
to ensure that, following the Effective Time, no holder of Thrifty PayLess
Stock Options or any participant in the Thrifty PayLess Option Plans or any
other plans, programs, agreements or arrangements will have any right
thereunder to acquire any equity securities of Thrifty PayLess or any
subsidiary thereof (except as otherwise described below under "--Bi-Mart
Options").
   
  Payments Under Cash Bonus Plan. Provided that Thrifty PayLess achieves
certain performance objectives, Rite Aid will pay bonuses to Thrifty PayLess
employees covered by the Thrifty PayLess Executive Incentive Plan (the "Cash
Bonus Plan") in respect of the fiscal year of Thrifty PayLess beginning on
September 30, 1996 and ending on the date of the Effective Time ("FY 1997").
Such bonuses will be (a) based upon the Thrifty PayLess Board-approved EBITDA
budget of $285.3 million for the fiscal year ending September 28, 1997, (b)
prorated to reflect the fact that FY 1997 will terminate on the date of the
Effective Time rather than on September 28, 1997 (provided that the prorated
amount will not be less than it would have been if the Effective Time occurred
on December 29, 1996, which would have been the end of Thrifty PayLess' first
fiscal quarter of 1997 but for the Merger), (c) calculated and paid by Rite
Aid based on a percentage (determined by resolution of the Compensation
Committee of the Thrifty PayLess Board) of annual salary for the year ending
September 28, 1997, (d) paid on the date 90 calendar days after the end of FY
1997, and (e) payable by Rite Aid (or, if applicable, a subsidiary thereof) to
each employee eligible therefor who was employed by Thrifty PayLess as of the
last day of FY 1997.     
   
  Consulting Agreements. Upon the Effective Time, Rite Aid will also enter
into consulting agreements with certain Thrifty PayLess employees.     
   
  Thrifty PayLess Deferred Compensation Plan for Non-Management Directors. In
accordance with the Thrifty PayLess Deferred Compensation Plan, certain
members of the Thrifty PayLess Board, consisting of     
 
                                      36
<PAGE>
 
Leonard I. Green, Jonathan D. Sokoloff, Jennifer Holden Dunbar and Richard J.
Lynch, Jr., have previously elected to defer their director cash compensation.
In accordance with the terms of such plan, upon their termination as directors
of Thrifty PayLess at the Effective Time, such directors will be entitled to
cash payments equal to the number of units allotted to them under such plan
multiplied by the average closing sales price of Thrifty PayLess Common Stock
on the NYSE for the ten-day period immediately prior to the date of the
Effective Time.
   
  Bi-Mart Options. Pursuant to certain existing arrangements with various
officers of Bi-Mart, such officers have received or may receive options to
acquire up to an aggregate number of shares of Bi-Mart not to exceed 20% of
the issued and outstanding capital stock of Bi-Mart. Such options will remain
outstanding and in full force and effect following consummation of the Merger.
Rite Aid currently anticipates that it will divest Bi-Mart following the
Merger.     
 
DIRECTORS' AND OFFICERS' INSURANCE AND INDEMNIFICATION
   
  Pursuant to the Merger Agreement, Rite Aid agreed that at all times after
the Effective Time it will indemnify such 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 Thrifty PayLess or of any of Thrifty PayLess'
subsidiaries, successors and assigns (individually an "Indemnified Party" and
collectively the "Indemnified Parties"), to the fullest extent required or
permitted under the Certificate of Incorporation or By-Laws of Thrifty
PayLess, or any agreement with Thrifty PayLess, in each case as in effect
immediately prior to the execution of the Merger Agreement, 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, state of affairs or occurrence 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 maintain in effect for not less than six years after the Effective
Time the current policies of directors' and officers' liability insurance
maintained by Thrifty PayLess and its subsidiaries on the date of the Merger
Agreement (provided that Rite Aid may substitute therefor policies having at
least the same coverage, a comparably rated issuer 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 exceed 200% of the per annum
rate of the aggregate premium paid by Thrifty PayLess and its subsidiaries for
such insurance on the date of Merger Agreement, then Rite Aid 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 will 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
described under this paragraph. The rights described under this paragraph are
in addition to rights that an Indemnified Party may have under the Certificate
of Incorporation, By-Laws, other similar organization documents of Thrifty
PayLess 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.     
 
CERTAIN PROJECTED FINANCIAL INFORMATION
 
  In the course of the discussions giving rise to the Merger Agreement (see
"--Background of the Merger"), representatives of Thrifty PayLess furnished
representatives of Rite Aid certain business and financial information that
was not publicly available, including Thrifty PayLess' budget for its fiscal
year ending September 28, 1997 ("Thrifty PayLess' 1997 Budget"). Thrifty
PayLess' 1997 Budget included certain projections for fiscal 1997 prepared
solely for Thrifty PayLess' internal purposes. None of such projected
financial information provided by Thrifty PayLess to Rite Aid was prepared for
publication or with a view to complying with the published guidelines of the
Commission regarding projections or with the AICPA Guide for Prospective
Financial Statements, and such information is being included in this Joint
Proxy
 
                                      37
<PAGE>
 
Statement/Prospectus solely because it was furnished to Rite Aid in connection
with the discussions giving rise to the Merger Agreement.
 
  The projected financial information set forth below necessarily reflects
numerous assumptions with respect to general business and economic conditions
and other matters, many of which are inherently uncertain or beyond Thrifty
PayLess' control, and does not take into account any change in ownership of
Thrifty PayLess or any changes to Thrifty PayLess' operations or capital
structure which may result from the Merger. See "--Rite Aid's Reasons for the
Merger; Recommendation of the Rite Aid Board" and "Available Information--
Certain Forward-Looking Statements and Merger Considerations." It is not
possible to predict whether the assumptions made in preparing the projected
financial information will be valid and actual results may prove to be
materially higher or lower than those contained in the projections. The
inclusion of this information should not be regarded as an indication that
Rite Aid or anyone else who received this information considered it a reliable
predictor of future events, and this information should not be relied on as
such. Neither Rite Aid nor Thrifty PayLess assumes any responsibility for the
validity, reasonableness, accuracy or completeness of the projected financial
information, and Thrifty PayLess has made no representation to Rite Aid
regarding such information. See "Available Information--Certain Forward-
Looking Statements and Merger Considerations."
 
  Set forth below is a summary of estimated selected income statement
information provided by Thrifty PayLess to Rite Aid as described above (in
millions):

                                                             FOR THE YEAR ENDING

The principal assumptions underlying the foregoing projections are (i) an
increase in same-store sales of 6.1% (i.e., pharmacy sales increase of 12.4%
and non-pharmacy sales increase of 2.7%), (ii) a gross margin of 26.8% (as
compared with a projected gross margin of 26.5% in fiscal 1996), (iii) the
opening of 30 new stores during the course of the fiscal year, and (iv) an
increase in pharmacy sales to 36.8% of total sales, including growth of third-
party sales to 78.1% of total pharmacy sales. Included in the projected
financial information is $385.1 million in revenues and $4.1 million in net
income from Bi-Mart, which Rite Aid intends to divest following the Merger.
See "--Rite Aid's Reasons for the Merger; Recommendation of the Rite Aid
Board."
 
REFINANCING OF CERTAIN THRIFTY PAYLESS INDEBTEDNESS
 
  Pursuant to the Merger Agreement, Rite Aid agreed to refinance certain
existing debt of Thrifty PayLess. As of the Effective Time, Rite Aid intends
to refinance all of Thrifty PayLess' obligations under its secured bank
facility ($605.4 million aggregate principal amount and $104.0 million of
letters of credit outstanding at September 29, 1996). In addition, if the
Merger is consummated, Rite Aid would be obligated to offer to repurchase the
TPI Sub Debt ($195.0 million aggregate principal amount outstanding at
September 29, 1996) at 101% of the principal amount thereof. Rite Aid is
considering the possibility of commencing an offer to purchase all of the TPI
Sub Debt at a premium that is likely to substantially exceed the premium
payable under the Change of Control Offer, plus accrued and unpaid interest to
the date of purchase. Any such offer would be subject to various conditions,
including the consummation of the Merger. There can be no assurance that any
such offer to purchase will be made or as to the timing and terms thereof.
 
  Rite Aid intends to refinance such indebtedness as well as other Thrifty
PayLess' indebtedness and to pay related fees and expenses of approximately
$29 million with funds from an additional $1 billion bank revolving credit
facility. As of the date hereof, the structure, terms and provisions of such
facility are being negotiated and have not yet been finalized. Subsequently,
Rite Aid plans to refinance part of its bank debt on a long term basis through
senior debt issuances.

ACCOUNTING TREATMENT
 
  The Merger will be accounted for under the "purchase" method of accounting
in accordance with generally accepted accounting principles ("GAAP").
 
CERTAIN LEGAL MATTERS; REGULATORY APPROVALS
 
  General. The business of Thrifty PayLess is subject to numerous federal,
state and local licensing and registration regulations. For instance, Thrifty
PayLess' pharmacists and pharmacy technicians are required to be licensed by
the appropriate state board of pharmacy, and Thrifty PayLess' stores and
certain of Thrifty PayLess' distribution centers are also registered with the
Federal Drug Enforcement Administration. Further, many of Thrifty PayLess'
stores sell alcoholic beverages and certain of its stores sell ammunition, and
such stores are subject to various state and local liquor and firearm
licensing requirements as a result. By virtue of these license and
registration requirements, Thrifty PayLess and/or Rite Aid will be obligated
to obtain certain governmental consents and approvals in connection with the
Merger, which Rite Aid and Thrifty PayLess are currently in the process of
seeking. 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 Thrifty
PayLess or Rite Aid or that certain parts of the businesses of Thrifty PayLess
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. It is a condition of
the Merger that all consents, authorizations, orders, and approvals of (or
filings or registrations with) any governmental entity required in connection
with the Merger Agreement shall have been obtained or made, subject to certain
exceptions. Except as otherwise disclosed herein (including under "--
Antitrust" below), based upon its review of publicly available information
with respect to Thrifty PayLess and the review of certain information
furnished by Thrifty PayLess to Rite Aid, Rite Aid is not aware of any license
or regulatory permit that appears to be material to the business of Thrifty
PayLess and its subsidiaries, taken as a whole, that might be adversely
affected as a result of the Merger.
   
  Antitrust. Under the Hart-Scott-Rodino Antitrust Act of 1976, as amended
(the "HSR Act") and the regulations promulgated thereunder by the FTC, the
Merger 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 Merger is conditioned upon the expiration or termination of the applicable
waiting period under the HSR Act. On October 22, 1996, Rite Aid and Thrifty
PayLess filed notifications and report forms under the HSR Act with the FTC
and the Antitrust Division, and on November 6, 1996, Rite Aid and Thrifty
PayLess received official notice from the FTC of early termination of the
waiting period under the HSR Act, effective as of such date.     
   
  At any time before or after the Effective Time, notwithstanding such early
termination of the waiting period under the HSR Act, the FTC, the Antitrust
Division or any state could take such action under the antitrust laws of the
United States or such state, as the case may be, 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
Thrifty PayLess. State governmental authorities or private persons may also
seek to take legal action under the antitrust laws under certain
circumstances.     
   
  Closing Condition. The respective obligations of Rite Aid and Thrifty
PayLess 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 "The Merger Agreement--Conditions to the
Merger."     
 
APPRAISAL RIGHTS
 
  Under the DGCL, holders of B Common Stock are not entitled to appraisal or
dissenters' rights in connection with the Merger because the B Common Stock is
listed on a national securities exchange and the consideration which such
holders will be entitled to receive in the Merger will consist solely of (i)
Rite Aid
 
                                      39
<PAGE>
 
Common Stock, which will also be listed on a national securities exchange, and
(ii) cash in lieu of fractional shares. Under the DGCL, holders of Rite Aid
Common Stock are not entitled to appraisal or dissenters rights in connection
with the Merger because the Rite Aid Common Stock is listed on a national
securities exchange.
 
  Holders of record of A Common Stock who comply with the applicable statutory
procedures summarized herein will be entitled to appraisal rights under
Section 262 of the DGCL ("Section 262") because the A Common Stock is not
listed on a national securities exchange. A person having a beneficial
interest in shares of A Common Stock held of record in the name of another
person, such as a broker or nominee, must act promptly to cause the record
holder to follow the steps summarized below properly and in a timely manner to
perfect appraisal rights.
 
  THE FOLLOWING DISCUSSION IS NOT A COMPLETE STATEMENT OF THE LAW PERTAINING
TO APPRAISAL RIGHTS FOR THE A COMMON STOCK UNDER THE DGCL AND IS QUALIFIED IN
ITS ENTIRETY BY THE FULL TEXT OF SECTION 262 WHICH IS REPRINTED IN ITS
ENTIRETY AS APPENDIX D TO THIS JOINT PROXY STATEMENT/PROSPECTUS. ALL
REFERENCES IN SECTION 262 AND IN THIS SUMMARY TO A "STOCKHOLDER" OR "HOLDER"
ARE TO THE RECORD HOLDER OF THE SHARES OF A COMMON STOCK AS TO WHICH APPRAISAL
RIGHTS ARE ASSERTED.
 
  Under the DGCL, holders of shares of A Common Stock ("Appraisal Shares") who
follow the procedures set forth in Section 262 will be entitled to have their
Appraisal Shares appraised by the Delaware Chancery court and to receive
payment in cash of the "fair value" of such Appraisal Shares, exclusive of any
element of value arising from the accomplishment or expectation of the Merger,
together with a fair rate of interest, if any, as determined by such court.
 
  Under Section 262, where a proposed merger is to be submitted for approval
at a meeting of stockholders, the corporation, not less than 20 days prior to
the meeting, must notify each of its stockholders who was such on the record
date for such meeting with respect to shares for which appraisal rights are
available, that appraisal rights are so available, and must include in such
notice a copy of Section 262.
 
  This Joint Proxy Statement/Prospectus constitutes such notice to the holders
of Appraisal Shares and the applicable statutory provisions of the DGCL are
attached to this Joint Proxy Statement/Prospectus as Annex D. Any stockholder
who wishes to exercise such appraisal rights or who wishes to preserve his
right to do so should review the following discussion and Annex D carefully,
because failure to timely and properly comply with the procedures specified
will result in the loss of appraisal rights under the DGCL.
   
  A HOLDER OF APPRAISAL SHARES WISHING TO EXERCISE SUCH HOLDER'S APPRAISAL
RIGHTS MUST DELIVER TO THRIFTY PAYLESS PRIOR TO THE VOTE ON THE MERGER
AGREEMENT AT THE THRIFTY PAYLESS SPECIAL MEETING TO BE HELD ON DECEMBER 12,
1996, A WRITTEN DEMAND FOR APPRAISAL OF SUCH HOLDER'S APPRAISAL SHARES. A
PROXY OR VOTE AGAINST THE MERGER AGREEMENT WILL NOT CONSTITUTE SUCH A DEMAND.
A HOLDER OF APPRAISAL SHARES WISHING TO EXERCISE SUCH HOLDER'S APPRAISAL
RIGHTS MUST BE THE RECORD HOLDER OF SUCH APPRAISAL SHARES ON THE DATE THE
WRITTEN DEMAND FOR APPRAISAL IS MADE AND MUST CONTINUE TO HOLD SUCH APPRAISAL
SHARES OF RECORD THROUGH THE EFFECTIVE DATE OF THE MERGER. ACCORDINGLY, A
HOLDER OF APPRAISAL SHARES WHO IS THE RECORD HOLDER OF APPRAISAL SHARES ON THE
DATE THE WRITTEN DEMAND FOR APPRAISAL IS MADE, BUT WHO THEREAFTER TRANSFERS
SUCH APPRAISAL SHARES PRIOR TO THE CONSUMMATION OF THE MERGER, WILL LOSE ANY
RIGHT TO APPRAISAL IN RESPECT OF SUCH APPRAISAL SHARES.     
 
  Only a holder of record of Appraisal Shares is entitled to assert appraisal
rights for the Appraisal Shares registered in that holder's name. A demand for
appraisal should be executed by or on behalf of the holder of record, fully
and correctly, as such holder's name appears on such holder's stock
certificates. If the Appraisal Shares are owned of record in a fiduciary
capacity, such as by a trustee, guardian or custodian, execution of the demand
should be made in that capacity, and if the Appraisal Shares are owned of
record by more than one person as in a joint tenancy or tenancy in common, the
demand should be executed by or on behalf of all joint owners. An authorized
agent, including one or more joint owners, may execute a demand for appraisal
on behalf of a holder of record; however, the agent must identify the record
owner or owners and expressly disclose the
 
                                      40
<PAGE>
 
fact that, in executing the demand, the agent is agent for such owner or
owners. A record holder such as a broker who holds Appraisal Shares as nominee
for several beneficial owners may exercise appraisal rights with respect to
the Appraisal Shares held for one or more beneficial owners while not
exercising such rights with respect to the Appraisal Shares held for other
beneficial owners; in such case, the written demand should set forth the
number of Appraisal Shares as to which appraisal is sought. When no number of
Appraisal Shares is expressly mentioned, the demand will be presumed to cover
all Appraisal Shares held in the name of the record owner. If a stockholder
holds Appraisal Shares through a broker who in turn holds the shares through a
central securities depositary nominee, a demand for appraisal of shares must
be made by or on behalf of the depositary nominee and must identify the
depositary nominee as record holder. Stockholders who hold their Appraisal
Shares in brokerage accounts or other nominee forms and who wish to exercise
appraisal rights are urged to consult with their brokers to determine the
appropriate procedures for the making of a demand for appraisal by such a
nominee.
 
  ALL WRITTEN DEMANDS FOR APPRAISAL SHOULD BE SENT OR DELIVERED TO THRIFTY
PAYLESS HOLDINGS, INC. AT 9725 S.W. PEYTON LANE, WILSONVILLE, OREGON 97070,
ATTENTION: SECRETARY.
 
  Within 10 days after the consummation of the Merger, Rite Aid will notify
each stockholder who has properly asserted appraisal rights under Section 262
of the date the Merger became effective.
 
  Within 120 days after the consummation of the Merger, but not thereafter,
the Surviving Corporation or any stockholder who has complied with the
statutory requirements summarized above may file a petition in the Delaware
Chancery Court demanding a determination of the fair value of the Appraisal
Shares. The Surviving Corporation is under no obligation, and has no present
intention, to file a petition with respect to the appraisal of the fair value
of the Appraisal Shares. Accordingly, it is the obligation of the stockholders
to initiate all necessary action to perfect their appraisal rights within the
time prescribed in Section 262.
 
  Within 120 days after the consummation of the Merger, any stockholder who
has complied with the requirements for exercise of appraisal rights will be
entitled, upon written request, to receive from the Surviving Corporation a
statement setting forth the aggregate number of Appraisal Shares with respect
to which demands for appraisal have been received and the aggregate number of
holders of such Appraisal Shares. Such statements must be mailed within ten
days after a written request therefor has been received by the Surviving
Corporation.
 
  If a petition for an appraisal is timely filed, after a hearing on such
petition, the Delaware Chancery Court will determine the stockholders entitled
to appraisal rights and will appraise the "fair value" of their Appraisal
Shares, exclusive of any element of value arising from the accomplishment or
expectation of the Merger, together with a fair rate of interest, if any, to
be paid upon the amount determined to be the fair value. Stockholders
considering seeking appraisal should be aware that the fair value of their
Appraisal Shares as determined under Section 262 could be more than, the same
as or less than the value of the consideration they would receive pursuant to
the Merger Agreement if they did not seek appraisal of their Appraisal Shares
and that investment banking opinions as to fairness are not necessarily
opinions as to fair value under Section 262. The Delaware Supreme Court has
stated that "proof of value by any techniques or methods which are generally
considered acceptable in the financial community and otherwise admissible in
court" should be considered in the appraisal proceedings.
 
  If a petition for an appraisal is timely filed, at the hearing on such
petition the Delaware Court will determine which stockholders are entitled to
appraisal rights. The Delaware Court may require the stockholders who have
demanded an appraisal for their shares to submit their certificates of stock
to the Register in Chancery for notation thereon of the pendency of the
appraisal proceedings. If any stockholder fails to comply with such direction,
the Delaware Court may dismiss the proceedings as to such stockholder.
 
  The Delaware Chancery Court will determine the amount of interest, if any,
to be paid upon the amounts to be received by persons whose Appraisal Shares
have been appraised. The costs of the action may be determined by the Delaware
Chancery Court and taxed upon the parties as the Delaware Chancery Court deems
equitable.
 
                                      41
<PAGE>
 
The Delaware Chancery Court may also order that all or a portion of the
expenses incurred by any stockholder in connection with an appraisal,
including, without limitation, reasonable attorneys' fees and the fees and
expenses of experts utilized in the appraisal proceeding, be charged pro rata
against the value of the all of the Appraisal Shares entitled to appraisal.
 
  Any holder of Appraisal Shares who has duly demanded an appraisal in
compliance with Section 262 will not, after the consummation of the Merger, be
entitled to vote the Appraisal Shares subject to such demand for any purpose
or be entitled to the payment of dividends or other distributions on those
Appraisal Shares (except dividends or other distributions payable to holders
of record of Appraisal Shares as of a record date prior to the consummation of
the Merger).
 
  If any stockholder who properly demands appraisal of his Appraisal Shares
under Section 262 fails to perfect, or effectively withdraws or loses, his
right to appraisal, as provided in the DGCL the Appraisal Shares of such
stockholder will be converted into the right to receive the consideration
receivable with respect to such Appraisal Shares in accordance with the Merger
Agreement. A stockholder will fail to perfect, or effectively lose or
withdraw, his right to appraisal if, among other things, no petition for
appraisal is filed within 120 days after the effective date of the Merger, or
if the stockholder withdraws his demand for appraisal. Any withdrawal
attempted more than 60 days after such effective date will require the written
approval of the Surviving Corporation. Notwithstanding the foregoing, no
appraisal proceeding pending in the Court of Chancery shall be dismissed as to
any stockholder without the approval of the Court, and any such approval may
be conditioned upon such terms as the Court deems just.
 
  FAILURE TO FOLLOW THE STEPS REQUIRED BY SECTION 262 FOR PERFECTING APPRAISAL
RIGHTS MAY RESULT IN THE LOSS OF SUCH RIGHTS (IN WHICH EVENT A STOCKHOLDER
WILL BE ENTITLED TO RECEIVE THE CONSIDERATION RECEIVABLE WITH RESPECT TO SUCH
APPRAISAL SHARES IN ACCORDANCE WITH THE MERGER AGREEMENT).
 
AMENDMENT OF RITE AID CERTIFICATE OF INCORPORATION
   
  Pursuant to the Merger Agreement and in connection with the Merger, the
Certificate of Incorporation of Rite Aid ("Rite Aid Charter") will be amended
to, among other things, change the authorized capital stock from 240,000,000
shares of Common Stock to 300,000,000 shares of Common Stock, simplify the
purpose clause, remove certain obsolete provisions and effect certain other
minor technical amendments. The complete text of the Rite Aid Charter as it is
being amended pursuant to the Merger Agreement is included herein as Exhibit C
to Annex A of this Joint Proxy Statement/Prospectus.     
   
  The Rite Aid Charter currently authorizes the issuance of 240,000,000 shares
of Rite Aid Common Stock and 20,000,000 shares of Rite Aid Preferred Stock. On
the Rite Aid Record Date, 83,928,120 shares of Rite Aid Common Stock were
issued and outstanding. Rite Aid expects to issue approximately 38,676,000
shares of Rite Aid Common Stock to holders of Thrifty PayLess Common Stock in
the Merger. Additionally, 6,419,037 shares are reserved for issuance to or on
behalf of participants in the Rite Aid 1990 Omnibus Stock Incentive Plan upon
the exercise of options granted pursuant to such plans and 5,953,266 shares
are reserved for issuance pursuant to the terms of Rite Aid's convertible
debt. After taking into account the shares of Rite Aid Common Stock either
issued or reserved for issuance, including those to be issued pursuant to the
Merger and those reserved for the foregoing stock plan, Rite Aid would have
only 105,023,577 remaining shares authorized for issuance if the Rite Aid
Charter were not amended.     
 
  The Rite Aid Board believes it is desirable to authorize additional shares
of Rite Aid Common Stock so that there will be sufficient shares available for
issuance after the Merger for purposes that the Rite Aid Board may hereafter
determine to be in the best interests of Rite Aid and its stockholders. Such
purposes could include the offer of shares for cash, acquisitions, employee
benefit programs and other general corporate purposes. In many situations,
prompt action may be required which would not permit seeking stockholder
approval to authorize additional shares for the specific transaction on a
timely basis. The Rite Aid Board believes it should have the flexibility to
act promptly in the best interests of stockholders. The terms of any future
issuance of
 
                                      42
<PAGE>
 
shares of Rite Aid Common Stock will be dependent largely on market and
financial conditions and other factors existing at the time of issuance. For
the foregoing reasons, the Merger Agreement provides that the authorized shares
of Rite Aid Common Stock will be increased in order to have a sufficient number
of shares for issuance from time to time after the Merger.
 
  Rite Aid currently has no agreements or special plans concerning the issuance
of additional shares of Rite Aid Common Stock, except for the shares to be
issued in the Merger and shares reserved or to be reserved for issuance by Rite
Aid as described herein. If any agreements or plans are made concerning the
issuance of any such shares, holders of the then outstanding shares of Rite
Aid's capital stock may or may not be given the opportunity to vote thereon,
depending upon the nature of any such transaction, the law applicable thereto,
the policy of the NYSE and the judgment of the Rite Aid Board regarding the
submission thereof to Rite Aid's stockholders. The current rules of the NYSE,
however, would require stockholder approval if the number of shares of Rite Aid
Common Stock to be issued would equal or exceed 20% of the number of such
shares of Rite Aid Common Stock outstanding immediately prior to such issuance.
 
  It is not presently contemplated that such additional shares of Rite Aid
Common Stock would be issued for the purpose of making the acquisition by an
unwanted suitor of a controlling interest in Rite Aid more difficult, time-
consuming or costly. However, it should be noted that shares of Rite Aid Common
Stock could be issued for that purpose and to that effect, and the Rite Aid
Board reserves its right (if consistent with its fiduciary responsibilities) to
issue Rite Aid Common Stock for such purposes.
   
  Additionally, the Rite Aid Charter will be amended to simplify the purpose of
Rite Aid to be to engage in any lawful act or activity for which corporations
may be organized under the DGCL, to remove provisions regarding indemnification
that were superseded by the 1987 amendment to the Rite Aid Charter and to make
certain other minor technical corrections.     
 
RESALES OF RITE AID COMMON STOCK
 
  All shares of Rite Aid Common Stock issued pursuant to the Merger 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 Thrifty PayLess 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.
 
  Thrifty PayLess has agreed to deliver to Rite Aid, not later than the record
date for the Thrifty PayLess Special Meeting, a letter identifying, to the best
of Thrifty PayLess' knowledge, all persons who are, at the time of the Thrifty
PayLess Special Meeting, deemed to be "affiliates" (as used in the preceding
paragraph) of Thrifty PayLess 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
Thrifty PayLess, 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 Thrifty PayLess 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.
 
  Pursuant to the GEI/Kmart Stockholder Agreements, GEI and Kmart each have
and, in the event GEI distributes its shares of Rite Aid Common Stock to its
limited partners, such limited partners will have, the right to require Rite
Aid to register the shares of Rite Aid Common Stock owned by them, subject to
certain terms and conditions. In particular, Kmart's demand rights entitle it,
among other things, to make a demand for registration at any time prior to the
Effective Time and, upon such demand, Rite Aid is required to use reasonable
efforts to cause a registration statement with respect to Kmart's shares of
Rite Aid Common Stock to become effective as promptly as practicable following
the Effective Time. There is no limitation on the right of GEI to distribute
its shares of Rite Aid Common Stock to its limited partners. See "The GEI/Kmart
Stockholder Agreements--Registration Rights."

NEW YORK STOCK EXCHANGE LISTING
 
  Rite Aid has agreed to use reasonable efforts to list, prior to the
Effective Time, on the NYSE, subject to official notice of issuance, the
shares of Rite Aid Common Stock to be issued in the Merger, and such listing
is a condition to the consummation of the Merger. Rite Aid also intends to
list such shares of Rite Aid Common Stock on the PSE.
 
                             THE MERGER AGREEMENT
   
  The following summary of the Merger Agreement 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, 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.     
 
GENERAL
   
  The Merger Agreement provides that, subject to the terms and conditions
thereof and in accordance with the DGCL, at the Effective Time, Rite Aid and
Thrifty PayLess will consummate the Merger pursuant to which (i) Thrifty
PayLess will be merged with and into Rite Aid and the separate corporate
existence of Thrifty PayLess shall thereupon cease, and (ii) Rite Aid will be
the Surviving Corporation and will continue to be governed by the laws of the
State of Delaware. Pursuant to the Merger, (a) the Certificate of
Incorporation of Rite Aid, as amended in the manner described under "The
Merger--Amendment of Rite Aid Certificate of Incorporation," will be the
Certificate of Incorporation of the Surviving Corporation until thereafter
amended as provided by law and such Certificate of Incorporation, and (b) the
By-laws of Rite Aid, 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. See "The Merger--Amendment of Rite Aid Certificate of
Incorporation." The Merger will have the effects set forth in the DGCL.     
 
  The Merger Agreement provides that each share of A Common Stock and B Common
Stock of Thrifty PayLess issued and outstanding immediately prior to the
Effective Time (other than Thrifty PayLess Common Stock owned by Thrifty
PayLess as treasury stock, any Thrifty PayLess Common Stock owned by Rite Aid
or any direct or indirect wholly owned subsidiary of Rite Aid or Thrifty
PayLess and Dissenting Thrifty PayLess Shares, if any) 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 0.65 duly authorized, validly
issued, fully paid and nonassessable shares of Rite Aid Common Stock.
 
  All shares of Thrifty PayLess Common Stock that are owned by Thrifty PayLess
as treasury stock and any shares of Thrifty PayLess Common Stock owned by Rite
Aid or any direct or indirect wholly owned subsidiary of Rite Aid or Thrifty
PayLess will, at the Effective Time, be cancelled and retired and will cease
to exist and no Rite Aid Common Stock 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 Thrifty PayLess Common Stock (the "Certificates") will
cease to have any rights as stockholders of Thrifty PayLess, except the right
to receive the consideration set forth in the Merger Agreement for each share
of Thrifty PayLess Common Stock held by them or, if applicable, payments due
to holders of Dissenting Thrifty PayLess Shares. See "The Merger--Appraisal
Rights for Thrifty PayLess Stockholders."
 
  In lieu of any fractional share of Rite Aid Common Stock, Rite Aid will pay
to each former stockholder of Thrifty PayLess who otherwise would be entitled
to receive a fractional share of Rite Aid Common Stock an amount in cash
determined by multiplying (i) the Rite Aid Share Price by (ii) the fractional
interest in a share of Rite Aid Common Stock to which such holder would
otherwise be entitled.
 
  AS SOON AS PRACTICABLE AFTER THE EFFECTIVE TIME, A BANK OR TRUST COMPANY
DESIGNATED BY RITE AID TO ACT AS AGENT FOR THE HOLDERS OF THRIFTY PAYLESS
COMMON STOCK IN CONNECTION WITH THE MERGER (THE
 
                                      44
<PAGE>
 
"EXCHANGE AGENT") WILL MAIL TO EACH HOLDER OF RECORD OF A CERTIFICATE WHOSE
SHARES WERE CONVERTED IN THE MERGER INTO THE RIGHT TO RECEIVE RITE AID COMMON
STOCK A LETTER OF TRANSMITTAL AND INSTRUCTIONS FOR USE IN EFFECTING THE
SURRENDER OF SUCH CERTIFICATES IN EXCHANGE FOR RITE AID COMMON STOCK.
 
  THRIFTY PAYLESS STOCKHOLDERS SHOULD NOT FORWARD THRIFTY PAYLESS STOCK
CERTIFICATES TO THE EXCHANGE AGENT UNTIL THEY HAVE RECEIVED SUCH TRANSMITTAL
LETTERS. THRIFTY PAYLESS STOCKHOLDERS SHOULD NOT RETURN STOCK CERTIFICATES
WITH THE ENCLOSED PROXY.
   
  In accordance with the Merger Agreement, effective as of the Effective Time,
each outstanding Thrifty PayLess Stock Option will be converted automatically
into a right to receive an amount of cash equal to (i) 65% of the Rite Aid
Share Price minus the exercise price per share under the applicable Thrifty
PayLess Stock Option, times (ii) the number of shares of Thrifty PayLess
Common Stock purchasable upon exercise of such Thrifty PayLess Stock Option.

  the ordinary course of business consistent with past practice;
     
    (vii) Neither Thrifty PayLess nor any of its subsidiaries will: (a) incur

    (xi) Neither Thrifty PayLess nor any of its subsidiaries will take, or

<PAGE>
 
    (xvii) Neither Thrifty PayLess nor any of its subsidiaries will enter
  into an agreement, contract, commitment or arrangement to do any of the

INTERIM OPERATIONS OF RITE AID
 
  In the Merger Agreement, Rite Aid has covenanted and agreed that, except as
expressly provided in the Merger Agreement or with the prior written consent
of Thrifty PayLess, during the term of the Merger Agreement:
 
    (i) Rite Aid will not, directly or indirectly, split, combine or
  reclassify the outstanding Rite Aid Common Stock;
 
    (ii) Neither Rite Aid nor any of its subsidiaries will declare, set aside
  or pay any dividend or other distribution payable in cash, stock or
  property with respect to its capital stock other than (a) dividends paid by
  Rite Aid's subsidiaries to Rite Aid or its subsidiaries and (b) cash
  dividends on Rite Aid Common Stock at Rite Aid's current dividend rate or
  as such rate may be increased (provided that any such increase is not
  higher on a percentage basis, after rounding up to avoid fractions, than
  Rite Aid's most recent dividend rate increase prior to date of the Merger
  Agreement) (in addition, in the Merger Agreement, Rite Aid acknowledged
  that its intention as of the date of the Merger Agreement was to continue
  to pay cash dividends at a rate no less than the most recent dividend prior
  to the date of the Merger Agreement);
 
    (iii) Rite Aid may not adopt a plan of complete or partial liquidation or
  dissolution;
 
    (iv) Neither Rite Aid nor any of its subsidiaries may take, or agree to
  commit to take, any action that would make any representation or warranty
  of Rite Aid in the Merger Agreement inaccurate in any material respect at,
  or as of any time prior to, the Effective Time; and
 
    (v) Neither Rite Aid nor any of its subsidiaries may enter into an
  agreement, contract, commitment or arrangement to do any of the foregoing,
  or to authorize, recommend, propose or announce an intention to do any of
  the foregoing.
 
NO SOLICITATION
 
  Pursuant to the Merger Agreement, Thrifty PayLess (and its subsidiaries and
Affiliates over which it exercises control) have agreed that they will not,
and Thrifty PayLess (and its subsidiaries and Affiliates over which it
exercises control) have agreed that they will cause their respective officers,
directors, investment bankers, attorneys, accountants and other agents not to,
directly or indirectly: (i) initiate, solicit or encourage (including by way
of furnishing information), or take any other similar action to facilitate the
making of, any offer or proposal which constitutes or is reasonably likely to
lead to, any Takeover Proposal or an inquiry with respect thereto, or (ii) in
the event of an unsolicited Takeover Proposal for Thrifty PayLess or any
subsidiary or Affiliate of Thrifty PayLess, 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, provided, however, that if the Thrifty PayLess Board
determines in good faith, having received and considered the advice of outside
counsel, that it is necessary to do so in order to comply with its fiduciary
duties to Thrifty PayLess' stockholders under applicable law, Thrifty PayLess
may, in response to a Takeover Proposal which was not solicited by it or which
did not otherwise result from a breach of the provisions cited under this
paragraph, and subject to compliance with all the other provisions cited under
this paragraph, (a) furnish information with respect to Thrifty PayLess and
its subsidiaries to any person pursuant to a customary confidentiality
agreement (as determined by Thrifty PayLess after consultation with its
outside counsel) and (b) participate in negotiations regarding such Takeover
Proposal. Thrifty PayLess has agreed to immediately notify Rite Aid orally and
in writing of any such request for information or Takeover Proposal that comes
to the attention of any of its officers or directors (including the material
terms and conditions thereof and the identity of the person making it) and to
keep Rite Aid reasonably informed of the status and details (including
amendments or proposed amendments) of any such request or Takeover Proposal.

  The Merger Agreement also provides that, except as expressly permitted by
the Merger Agreement, neither the Thrifty PayLess Board nor any committee
thereof may (i) withdraw or modify, or propose publicly to withdraw or modify,
in a manner adverse to Rite Aid, the approval or recommendation by the Thrifty
PayLess Board or such committee of the Merger or the Merger Agreement, (ii)
approve or recommend, or propose publicly to approve or recommend, any
Takeover Proposal (other than the Merger), or (iii) cause Thrifty PayLess to
enter into any letter of intent, agreement in principle, acquisition agreement
or other similar agreement (each, an "Acquisition Agreement") related to any
Takeover Proposal. Notwithstanding the foregoing, in the event that prior to
the adoption of the Merger Agreement by the holders of Thrifty PayLess Common
Stock, the Thrifty PayLess Board determines in good faith, after it has
received a Superior Proposal (defined below) and having received and
considered advice of outside counsel, that it is necessary to do so in order
to comply with its fiduciary duties to Thrifty PayLess' stockholders under
applicable law, the Thrifty PayLess Board may (subject to the provisions cited
in this paragraph and the other provisions of the Merger Agreement) withdraw
or modify its approval or recommendation of the Merger or the Merger
Agreement, but in any such case only at a time that is after the fifth
business day following Rite Aid's receipt of written notice advising Rite Aid
that the Thrifty PayLess Board has received a Superior Proposal, specifying
the material terms and conditions of such Superior Proposal and identifying
the person making such Superior Proposal.
 
  As used in the Merger Agreement, a "Superior Proposal" means any proposal
made by a third party to acquire, directly or indirectly, for consideration
consisting of cash and/or securities, more than 50% of the combined voting
power of the shares of Thrifty PayLess Common Stock then outstanding or all or
substantially all the assets of Thrifty PayLess and otherwise on terms which
the Thrifty PayLess Board determines in its good faith judgment (having
received and considered the advice of a financial advisor of nationally
recognized reputation) to be more favorable to Thrifty PayLess' stockholders
than the Merger and for which financing, to the extent required, is then
committed or which, in the good faith judgment of the Thrifty PayLess Board,
is reasonably capable of being obtained by such third party.
 
RITE AID STANDSTILL PROVISION
 
  In the Merger Agreement Rite Aid has agreed that, if the Merger Agreement is
terminated by either party in accordance with the terms of the Merger
Agreement, for a period of four years from the date of the Merger Agreement,
except within the terms of a specific written request from Thrifty PayLess and
except for certain purchases of Thrifty PayLess Common Stock permitted prior
to the termination of the Merger Agreement, Rite Aid will not, and will use
its best efforts to cause each of its Affiliates controlled by it not to,
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 (a) any form of business combination, acquisition,
restructuring, recapitalization or other similar transaction relating to
Thrifty PayLess or any subsidiary of Thrifty PayLess, or (b) any demand,
request or proposal to amend, waive or terminate any of the provisions cited
in this paragraph, and except as aforesaid during such period Rite Aid will
not, and will use its best efforts to cause each of its Affiliates or any of
its representatives as a principal not to, (i) acquire, or offer, propose or
agree to acquire, by purchase or otherwise, any additional voting securities
of Thrifty PayLess, (ii) make, or in any way participate in, any solicitation
of proxies with respect to any such voting securities (including by the
execution of action by written consent), become a participant in any election
contest with respect to Thrifty PayLess, seek to influence any person with
respect to any such voting securities or demand a copy of the list of the
stockholders or other books and records of Thrifty PayLess, (iii) 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 such
voting securities or which seeks to affect control of Thrifty PayLess or has
the purpose of circumventing any provision of the Merger Agreement, (iv)
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, Board of Directors or policies of Thrifty PayLess,
or (v) make any proposal or other communication designed to compel Thrifty
PayLess to make a public announcement in respect of any matter cited in this
paragraph; provided, however, that if Thrifty PayLess initiates a process of
soliciting bids for the acquisition of Thrifty PayLess, Rite Aid will be
permitted to participate in such process on the same basis, and subject to the
same conditions and limitations, as are
 
                                      48
<PAGE>
 
established by Thrifty PayLess for all bidders and if Thrifty PayLess enters
into an Acquisition Agreement with a party other than Rite Aid and, as a
result, the Thrifty PayLess Board has a fiduciary obligation under applicable
Delaware law to consider alternative Takeover Proposals, Rite Aid will be
permitted to make a Takeover Proposal.

Merger may be abandoned at any time prior to the Effective Time, whether
before or after stockholder approval thereof: (i) by the mutual consent of the
Rite Aid Board and Thrifty PayLess Board; (ii) by either Thrifty PayLess or
Rite Aid: (a) if the Merger shall not have been consummated by April 30, 1997
(and the party whose failure to perform any of its obligations under the
Merger Agreement is not the cause of the failure of the Merger to be
consummated by such time); (b) if, at the Thrifty PayLess Special Meeting duly
convened therefor and finally adjourned, the Thrifty PayLess stockholder
approval of the Merger shall not have been obtained; (c) if, at the Rite Aid
Special Meeting duly convened therefor and finally adjourned, the Rite Aid

Agreements and such Restraint or other action shall have become final and
nonappealable; (iii) by Rite Aid, if Thrifty PayLess shall be in Material
Breach (provided that Rite Aid is not then in Material Breach itself); (iv) by
Rite Aid if (a) the Thrifty PayLess Board or any committee thereof shall have

committee thereof shall have resolved to take any of the foregoing actions;
(v) by Rite Aid, if Thrifty PayLess or any of its officers, directors,

for the exceptions therein allowing certain actions to be taken based upon the
fiduciary obligations of the Thrifty PayLess Board; and (vi) by Thrifty
PayLess, if Rite Aid shall be in Material Breach (provided that Thrifty
PayLess is not then in Material Breach itself). As used in this paragraph, a
"Material Breach" is a failure to perform in any material respect any
representations, warranties, covenants or other agreements of the respective
party in the Merger Agreement, which breach or failure to perform cannot be or
has not been cured within 30 days after notice to the breaching party.
 
 
  Except as set forth below and except in the case of fraud or intentional
material breach of the Merger Agreement, neither party to the Merger Agreement
will have any liability to the other upon termination thereof in accordance
with its terms.
 
TERMINATION FEES
 
  The foregoing notwithstanding, in the event that (i) a Takeover Proposal
shall have been made known to Thrifty PayLess or any of its subsidiaries or
has been made directly to its stockholders generally or any person shall have
publicly announced an intention (whether or not conditional) to make a
Takeover Proposal and thereafter Thrifty PayLess stockholder approval of the
Merger is not obtained or (ii) the Merger Agreement is terminated by Rite Aid
because the Thrifty PayLess Board or any committee thereof has withdrawn or
modified
 
                                      50
<PAGE>
 
in a manner adverse to Rite Aid its approval or recommendation of the Merger
or the Merger Agreement or approved or recommended a Takeover Proposal, then
Thrifty PayLess will pay Rite Aid a Termination Fee plus Reimbursable
Expenses, except that no Termination Fee or Reimbursable Expenses will be
payable under the Merger Agreement to Rite Aid (i) if Rite Aid is in Material
Breach or (ii) for any reason other than specified in this paragraph.
 
  In the event that the Merger Agreement is terminated by Thrifty PayLess
because of Rite Aid's failure to obtain stockholder approval of the Merger at
a meeting of Rite Aid stockholders duly convened and finally adjourned or
because of Rite Aid's Material Breach, then Rite Aid will promptly pay Thrifty
PayLess a Termination Fee plus Reimbursable Expenses, except that no
Termination Fee or Reimbursable Expenses will be payable under the Merger
Agreement to Thrifty PayLess (i) if Thrifty PayLess is in Material Breach or
(ii) for any reason other than those specified in this paragraph.
 
OTHER FEES AND EXPENSES
 
  Except as described above, all fees and expenses incurred in connection with
the Merger, the Merger Agreement, the GEI/Kmart Stockholder Agreements and the
transactions contemplated thereby will be paid by the party incurring such
fees or expenses, whether or not the Merger is consummated, except that each
of Thrifty PayLess and Rite Aid will bear and pay one-half of the costs and
expenses incurred in connection with (i) the Commission filing fees and
printing and mailing costs associated with this Joint Proxy
Statement/Prospectus and (ii) the filing fees applicable to the premerger
notification and report forms under the HSR Act.
 
OTHER COVENANTS
   
  The Merger Agreement also contains certain other customary covenants and
requirements of the parties. Certain of such provisions are described
elsewhere in this Joint Proxy Statement/Prospectus; see "The Merger--Interests
of Certain Persons and Employee Matters--Severance Arrangements," "--LGA
Investment Banking Fee," "--Directorship," "--Directors' and Officers'
Insurance and Indemnification," "--Amendment of Rite Aid Certificate of
Incorporation" and "--Resales of Rite Aid Common Stock."

  The following summary of the material terms of the GEI/Kmart Stockholder
Agreements contained in this Joint Proxy Statement/Prospectus is not intended
to be a complete description of the terms and conditions thereof and is

VOTING OF THRIFTY PAYLESS COMMON STOCK
 
  Concurrently with the execution of the Merger Agreement, each of GEI and
Kmart, who together hold approximately 42% of the outstanding Thrifty PayLess
Common Stock as of the date hereof (such outstanding shares together with any
securities of Thrifty PayLess acquired between the date of the Merger
Agreement and the termination of the respective GEI/Kmart Stockholder
Agreement being referred to herein as the "Securities"), entered into its
respective GEI/Kmart Stockholder Agreement with Rite Aid. The GEI/Kmart
Stockholder Agreements provide that, subject to certain exceptions, during the
period commencing on the date of the Merger Agreement and continuing until the
first to occur of the Effective Time or termination of the Merger Agreement in
accordance with its terms, (i) such Stockholder will not sell or transfer any
of its respective Securities or any interest therein to any person, other than
a wholly owned subsidiary of such stockholder, and (ii) at any meeting
(whether annual or special and whether or not an adjourned or postponed
meeting) of the holders of Thrifty PayLess Common Stock, however called, or in
connection with any written consent of the holders of Thrifty PayLess Common
Stock, such stockholder will appear at the meeting or otherwise cause its
 
                                      51
<PAGE>
 
respective Securities to be counted as present thereat for purposes of
establishing a quorum and vote or consent (or cause to be voted or consented)
its respective Securities (a) in favor of the adoption of the Merger Agreement
and the approval of other actions contemplated by the Merger Agreement and the
respective GEI/Kmart Stockholder Agreement and any actions required in
furtherance thereof; (b) against any action or agreement that would result in
a breach in any respect of any covenant, representation or warranty or any
other obligation or agreement of Thrifty PayLess under the Merger Agreement or
the respective GEI/Kmart Stockholder Agreement; and (c) except as otherwise
agreed to in writing in advance by Rite Aid in its sole discretion, against
the following actions (other than the Merger and the transactions contemplated
by the respective GEI/Kmart Stockholder Agreement and the Merger Agreement):
(1) any Takeover Proposal or Acquisition Agreement (other than the Merger or
the Merger Agreement) and (2)(u) any change in a majority of the persons who
constitute the Thrifty PayLess Board; (v) any material change in the present
capitalization of Thrifty PayLess, including without limitation any proposal
to sell a substantial equity interest in Thrifty PayLess or its subsidiaries;
(w) any amendment of Thrifty PayLess' Certificate of Incorporation or By-laws;
(x) any other change in Thrifty PayLess' corporate structure or business; or
(y) any other action which, in the case of each of the matters referred to in
clauses (2)(u), (v), (w) or (x), is intended, or could reasonably be expected,
to impede, interfere with, delay, postpone or materially adversely affect the
Merger and the transactions contemplated by the respective GEI/Kmart
Stockholder Agreement and the Merger Agreement. The GEI/Kmart Stockholders may
not enter into any agreement or understanding with any person the effect of
which would be inconsistent with or violative of any provision contained in
this paragraph.
 
SUBSEQUENT STOCKHOLDER ACTIONS
 
  The GEI/Kmart Stockholder Agreements provide that, for a period of four
years from and after the Effective Time, at any meeting (whether annual or
special or whether or not an adjourned or postponed meeting of the holders of
Rite Aid Common Stock) or in connection with any written consent of the holder
of Rite Aid Common Stock, each of GEI and Kmart will vote or consent (or cause
to be voted or consented) all shares of Rite Aid Common Stock howsoever
acquired, then held of record, or beneficially owned, by such stockholder in
accordance with the recommendations of the Rite Aid Board.
 
PAYMENT TO RITE AID OF CERTAIN AMOUNTS RECEIVED
 
  If Rite Aid becomes entitled to a Termination Fee pursuant to the Merger
Agreement and Thrifty PayLess consummates a Takeover Proposal or enters into
an Acquisition Agreement with any other party during the 12 months following
the termination of the Merger Agreement, subject to the last sentence of this
paragraph, with respect to Securities for which either GEI or Kmart receives
cash consideration pursuant to the Takeover Proposal or Acquisition Agreement,
the GEI/Kmart Stockholder Agreements provide that such stockholder will
immediately upon the receipt thereof pay to Rite Aid an amount in cash (if
positive) (the "Differential Amount") equal to (i) the net pre-tax cash
proceeds received by such stockholder with respect to the shares of Thrifty
PayLess Common Stock or other Securities of Thrifty PayLess, including any
shares of Thrifty PayLess Common Stock into or for which any Securities are
convertible, exchangeable or exercisable, of such stockholder (such shares,
the "Subject Shares") in such transaction or in a sale of any of the
securities to a third party that was initiated by such stockholder within 12
months after the date that the Merger Agreement is terminated, minus (ii) the
product of (a) 65% of the average closing sales price for Rite Aid Common
Stock on the NYSE Composite Tape for the five NYSE trading days immediately
preceding the first public announcement of the transaction in which the
Subject Shares are sold (such amount, the "Basis Amount") times (b) the number
of Subject Shares. Any non-cash consideration received by GEI or Kmart in a
transaction otherwise of a type described above as part of the net proceeds
("Other Consideration") will be held by such stockholder until it shall have
received in cash upon the sale or other disposition of such Other
Consideration an amount equal to the Basis Amount times the number of Subject
Shares, whereupon all other securities or proceeds thereof will be immediately
paid to Rite Aid.

STANDSTILL PROVISIONS
 
  For a period of four years from the date of the Merger Agreement, except
within the terms of a specific written request from Rite Aid, each of GEI and

with any other person or directly or indirectly, (i) any form of business
combination, acquisition or other similar transaction relating to Rite Aid or

aforesaid during such period, neither such stockholder will (a) acquire, or
offer, propose or agree to acquire, by purchase or otherwise, any voting
securities of Rite Aid, in excess of 1% of Rite Aid's outstanding shares (not
counting for these purposes any shares of Rite Aid Common Stock acquired
pursuant to the Merger), (b) make, or in any way participate in, any
solicitation of proxies with respect to any such voting securities (including
by the execution of action by written consent), become a participant in any
election contest with respect to Rite Aid, seek to influence any person with
respect to any such voting securities or demand a copy of the list of the
stockholders or other books and records of Rite Aid, (c) 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 such voting
securities or which seeks to affect control of Rite Aid or has the purpose of
circumventing any provision of the respective GEI/Kmart Stockholder Agreement,
(d) 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, Board of Directors, or policies of Rite Aid, or
(e) make any proposal or other communication designed to compel Rite Aid to
make a public announcement thereof in respect of any matter referred to in
this paragraph.
 
NO SOLICITATION
 
  Under the GEI/Kmart Stockholder Agreements, each of GEI and Kmart has agreed
that it will not, and will cause its representatives 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 or any inquiry with respect
thereto or (ii) in the event of an unsolicited Takeover Proposal for Thrifty
PayLess or any affiliate of Thrifty PayLess, 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.
 
RESTRICTION ON TRANSFER, PROXIES AND NON-INTERFERENCE
 
  The GEI/Kmart Stockholder Agreements provide that neither GEI nor Kmart
will, directly or indirectly, prior to the Merger, subject to certain
exceptions, (i) offer for sale, sell, transfer, tender, pledge, encumber,
assign or otherwise dispose of, or enter into any contract, option or other
arrangement or understanding with respect to or consent to the offer for sale,
sale, transfer, tender, pledge, encumbrance, assignment or other disposition
of, any or all of the Securities or any interest therein; (ii) grant any
proxies or powers of attorney, deposit the Securities into a voting trust or
enter into a voting agreement with respect to the Securities; or (iii) take
any action that would make any representation or warranty of such stockholder
contained in the respective GEI/Kmart Stockholder Agreement untrue or
incorrect or would result in a breach by such stockholder of its obligations
under the respective GEI/Kmart Stockholder Agreement.
 
TERMINATION
 
  The GEI/Kmart Stockholder Agreements will 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 provisions for payment
of the Differential Amount and registration rights (described below) will
survive any termination for the terms specified in such provisions and the
provisions pertaining to the voting of Rite Aid Common Stock, the standstill
provisions and the registration rights will survive the consummation of the
Merger. Notwithstanding the foregoing, after the Effective Time, the
provisions pertaining to the voting of Rite Aid Common Stock and the
standstill provisions will terminate (i) as to GEI, if there has been a
distribution of the Rite Aid Common
 
                                      53
<PAGE>
 
Stock received by GEI pursuant to the Merger to the limited partners of GEI,
unless the persons or entities receiving the distribution would constitute a
"group" within the meaning of Section 13(d) of the Exchange Act with respect
to the securities of Rite Aid and (ii) as to GEI or Kmart, if such party at
any time no longer owns at least 2% of the outstanding shares of Rite Aid
Common Stock.
 
REGISTRATION RIGHTS
   
  The GEI/Kmart Stockholder Agreements provide that the GEI/Kmart Stockholders
will be entitled to cause Rite Aid to register Rite Aid Common Stock
beneficially owned by them and received pursuant to the Merger in accordance
with the terms and conditions of the GEI/Kmart Stockholder Agreements. Such
registration rights include both "demand" and "piggyback" rights. Pursuant to
the demand rights, GEI or Kmart may be in a position to sell all of their Rite
Aid Common Stock acquired in the Merger promptly following the consummation
thereof. In addition, Kmart's demand rights entitle it, among other things, to
make a demand for registration at any time before or after the Effective Time.
If Kmart were to exercise such rights prior to the Effective Time, Rite Aid
would be required to use reasonable efforts to cause a registration statement
with respect to Kmart's shares of Rite Aid Common Stock to become effective as
promptly as practicable following the Effective Time. Kmart has not notified
Rite Aid of its intentions with respect to such registration rights.

           UNAUDITED PRO FORMA CONDENSED CONSOLIDATED FINANCIAL DATA
 
  The following Unaudited Pro Forma Condensed Consolidated Statements of
Operations for the 26 weeks ended August 31, 1996 and the fiscal year ended
March 2, 1996 present unaudited pro forma operating results for Rite Aid as if
the Merger had occurred as of the beginning of the periods presented. The
following Unaudited Pro Forma Condensed Consolidated Balance Sheet presents
the unaudited pro forma financial condition of Rite Aid as if the Merger had
occurred as of August 31, 1996. The excess of the purchase price of Thrifty
PayLess over the net identifiable assets and liabilities of Thrifty PayLess is
reported as goodwill. The carrying values of Thrifty PayLess' net assets are
assumed to equal their fair values for purposes of these unaudited pro forma
condensed consolidated 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.
 
  The Unaudited 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 (see "The Merger--
Accounting Treatment"); (ii) the establishment by Rite Aid of an additional
$1.0 billion revolving credit facility to be provided to Rite Aid by a
syndicate of banks (the "Credit Facility"); (iii) the refinancing of $864.5
million of outstanding Thrifty PayLess debt as described in "The Merger--
Refinancing of Certain Thrifty PayLess Indebtedness" and in the accompanying
Notes to Unaudited Pro Forma Condensed Consolidated Financial Data; and (iv)
the Southeast Dispositions, the divestiture of Bi-Mart subsequent to the
Merger and other adjustments described in the accompanying Notes to Unaudited
Pro Forma Condensed Consolidated Financial Data. The pro forma adjustments are
based upon certain assumptions Rite Aid considered reasonable under the
circumstances. Final amounts will differ from those set forth in the following
unaudited pro forma condensed consolidated financial data.
 
  The unaudited pro forma condensed consolidated financial data does not
reflect any synergies expected by Rite Aid management to be realized after the
Merger (see "The Merger--Rite Aid's Reasons for the Merger; Recommendation of
the Rite Aid Board") or costs related to the Southeast Dispositions, inasmuch
as such costs are non-recurring. See "The Merger--Rite Aid's Reasons for the
Merger; Recommendation of the Rite Aid Board" for a discussion of the $65
million of cost benefits and synergies estimated by Rite Aid management to be
realized annually. The Notes to Unaudited Pro Forma Condensed Consolidated
Financial Data describe the other adjustments related to the Merger. Such
unaudited pro forma data also does not reflect the effect that any purchase of
Thrifty PayLess Common Stock by Rite Aid prior to the consummation of the
Merger would have on such financial information.
 
  THE UNAUDITED PRO FORMA CONDENSED CONSOLIDATED FINANCIAL DATA 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 AND OTHER TRANSACTIONS DESCRIBED HEREIN BEEN CONSUMMATED AT THE DATES
INDICATED, NOR IS IT NECESSARILY INDICATIVE OF THE FUTURE OPERATING RESULTS OR
FINANCIAL POSITION OF RITE AID FOLLOWING THE MERGER.
 
  The unaudited pro forma condensed consolidated financial data should be read
in conjunction with the consolidated financial statements of each of Rite Aid

                         NOTES TO UNAUDITED PRO FORMA
                     CONDENSED CONSOLIDATED FINANCIAL DATA
 
BASIS OF CONSOLIDATION
 
  Thrifty PayLess' most recent fiscal year data that is available is for the
year ended October 1, 1995. For purposes of the Unaudited Pro Forma Condensed
Consolidated Statement of Operations for the fiscal year ended March 2, 1996,
Rite Aid's historical information is from the fiscal year ended March 2, 1996,
and the results of operations for Thrifty PayLess are for the 52 weeks ended
December 31, 1995. For purposes of the interim Unaudited Pro Forma Condensed
Consolidated Statement of Operations for the 26 weeks ended August 31, 1996,
the results of operations for the 26-week period ended August 31, 1996 were
used for Rite Aid, and the results of operations for the 26-week period ended
June 30, 1996 were used for Thrifty PayLess.
 
  As a result of installing standardized store systems in all Thrifty PayLess
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 Thrifty PayLess 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 as a result of
increased purchasing power derived from the combination of the two companies.
See "The Merger--Rite Aid's Reasons for the Merger; Recommendation of the Rite
Aid Board." However, for 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 "Available Information--Certain Forward-Looking Statements."
 
DETERMINATION AND ALLOCATION OF PURCHASE PRICE
 
  Pursuant to the Merger Agreement, all of the outstanding Thrifty PayLess
Common Stock will be converted to Rite Aid Common Stock at the Exchange Ratio.
The final purchase price and the allocation of the assigned purchase price to
goodwill will either increase or decrease based on the movement of the stock
price. The following table sets forth the purchase price (in millions) based
on an assumed $33.75 per share market value, which amount is the closing price
for Rite Aid Common Stock on October 18, 1996.

PRO FORMA ADJUSTMENTS
 
  (a) Amortization of the estimated goodwill relating to the Merger of $999
      million over a forty-year period ($999 million/40 = $24.975 million).
      The historical goodwill reflected on the Thrifty PayLess balance sheet
      was being amortized over a fifteen-year period at $3.9 million per
      year. The remaining balance of
 
                                      59
<PAGE>
 
     $45 million of goodwill will be reconstituted as new goodwill and
     amortized over a forty-year period ($45 million / 40 = $1.125 million).
     Accordingly, the pro forma incremental charge to goodwill is $22.2
     million ($24.975 million + $1.125 million - $3.9 million). The pro forma
     adjustment for the 26-week period ended August 31, 1996 represents one-
     half of the annualized pro forma adjustment amount.
 
  (b) Reflects pro forma amortization of estimated financing fees for the
      Credit Facility, based upon estimated fees of $0.2 million for a 364-
      day Credit Facility, and debt issuance costs for $600 million in new
      senior debt of approximately $4.8 million amortized over the estimated
      ten- and thirty-year lives of the respective debt issuances ($2.1
      million / 10 years) plus ($2.7 million / 30 years). Rite Aid
      anticipates refinancing approximately $600 million of the Credit
      Facility with long-term fixed interest rate senior debt following
      consummation of the Merger. The pro forma adjustments for the 26-weeks
      ended August 31, 1996 represents one-half of the annualized pro forma
      adjustment amount.
 
  (c) Reflects the net pro forma additional interest expense on Rite Aid's
      total borrowings and the reversal of Thrifty PayLess' historical debt
      discount and fee amortization. It is assumed that, after completion of
      the Merger, Rite Aid will refinance or retire substantially all of
      Thrifty PayLess' outstanding debt to the extent practicable. See "The
      Merger--Refinancing of Certain Thrifty PayLess Indebtedness." The
      components of Rite Aid's total pro forma combined debt after Thrifty
      PayLess' debt is refinanced or retired are as follows:
 
      $200 million of Rite Aid senior 7.625% debt;
         
      $200 million of Rite Aid senior 6.875% debt;     
      $300 million of new Rite Aid senior 7.85% debt;
      $300 million of new Rite Aid senior 7.3% debt;
      $70.6 million of Rite Aid 6.2% other debt;
      $193 million of Rite Aid zero coupon bonds accreting interest at 6.75%;
      and
      Rite Aid's commercial paper indebtedness totalling $1.104 billion
      with a 5.5% weighted average interest rate.
 
    The pro forma combined interest expense reflects the difference between
    the interest rates currently available to Rite Aid and the historical
    rates of interest paid by Thrifty PayLess.
 
  (d) Income taxes have been calculated based on Rite Aid's effective
      statutory rate for the respective periods. Amortization of goodwill is
      not deductible for tax purposes.
 
  (e) Reflects the pro forma adjustment of LIFO inventories to value the
      inventory at fair market value. Rite Aid believes the adjusted 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 revisions pending completion of physical
      inventories.
 
  (f) Records pro forma purchase price allocation to goodwill for excess of
      purchase price over net assets and direct costs of the transaction,
      primarily financial advisory and legal fees. Based on the purchase of
      all of the outstanding shares of Thrifty PayLess Common Stock
      (approximately 59,502,000 shares) converted into Rite Aid Common Stock
      at an Exchange Ratio of 0.65 (approximately 38,676,000 shares) valued
      at an assumed Rite Aid market price of $33.75.
 
  (g) Records the estimated $5 million in financing fees for the Credit
      Facility and issuance of $600 million of new senior debt (see Note (b))
      and removes Thrifty PayLess' unamortized debt issue costs of
      $18 million.
 
  (h) Reclassifies the Thrifty PayLess historical net deferred tax assets and
      records the deferred tax impact of the fair value adjustment to
      inventory.
 
  (i) See "The Merger--Refinancing of Certain Thrifty PayLess Indebtedness"
      for a discussion of certain Thrifty PayLess indebtedness.
 
  (j) Records pro forma premium on assumed purchase of TPI Sub Debt. See "The
      Merger--Refinancing of Certain Thrifty PayLess Indebtedness."
 
                                      60
<PAGE>
 
  (k) Records the issuance of 38,676,000 shares of Rite Aid Common Stock at
      $33.75 per share at the 0.65 Exchange Ratio and the elimination of
      Thrifty PayLess' equity accounts.
 
  (l) Records the fair value adjustments for Thrifty PayLess fixed assets.
 
  (m) Rite Aid estimates that expenses associated with closing Thrifty
      PayLess' corporate headquarters, severance and retention costs of
      employees, and other Merger costs will be $105 million. These costs
      will be 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 available.
 
  (n) The pro forma adjustments for the Southeast Dispositions and Bi-Mart
      represent the reclassification of the Rite Aid stores being divested in
      Alabama, Georgia, Florida, North Carolina and South Carolina, and the
      proposed divestiture of the Thrifty PayLess' Bi-Mart stores. The table
      below presents the balances for the respective dispositions. Rite Aid
      estimates that it will receive approximately $200 million from the sale
      of stores in the Southeast Dispositions and between $50 to $80 million
      from the sale of Thrifty PayLess' Bi-Mart stores.

                     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") and Rite Aid's By-
laws 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 and the Rite Aid By-laws. 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").
Pursuant to the Merger Agreement, Rite Aid will amend the Rite Aid Charter to,
among other things, (i) change the authorized capital stock from 240,000,000
shares of Common Stock to 300,000,000 shares of Common Stock, (ii) simplify
the purpose of Rite Aid to be to engage in any lawful act or activity for
which corporations may be organized under the DGCL, (iii) remove provisions
regarding indemnification that were superseded by the 1987 amendment to the
Rite Aid Charter, and (iv) make certain other minor technical corrections. See
"The Merger--Amendment of Rite Aid Certificate of Incorporation." The complete
text of the Rite Aid Charter as it is being amended pursuant to the Merger
Agreement is included herein as Exhibit C to Annex A of this Joint Proxy
Statement/Prospectus.     
 
RITE AID PREFERRED STOCK
 
  No shares of Rite Aid Preferred Stock are issued or outstanding. 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. 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 COMMON STOCK
   
  Assuming that issuance of an estimated 38,676,000 shares of Rite Aid Common
Stock issuable to stockholders of Thrifty PayLess in the Merger occurred as of
the Rite Aid Record Date, 122,604,120 shares of Rite Aid Common Stock would
have been issued and outstanding as of the Rite Aid Record Date. An additional
6,532,169 shares of Rite Aid Common Stock were issued and held in the treasury
of Rite Aid, 5,953,266 shares were reserved for issuance pursuant to the terms
of Rite Aid's convertible debt and 6,419,037 shares of Rite Aid Common Stock
were reserved for issuance under Rite Aid's 1990 Omnibus Stock Incentive Plan.
    
  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 any outstanding Rite Aid Preferred
Stock.
 
  Each holder of Rite Aid Common Stock is entitled to one vote in respect of
each share of such stock. 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
issued pursuant to the Merger will be, duly authorized, validly issued, fully
paid and nonassessable, and the outstanding shares of Rite Aid Common Stock
are, and the shares of Rite Aid Common Stock issued pursuant to the Merger
upon notice of issuance will be, listed on the NYSE and the PSE.
 
CHANGE OF CONTROL
 
  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
 
                                      62
<PAGE>
 
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) certain other transactions resulting in a 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 nor more than 15 directors elected for three year staggered
terms. The Rite Aid By-laws provide that the number of directors on the Rite
Aid Board may be fixed by the Rite Aid Board only, or if the number is not
fixed, the number will be 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 Board currently consists of 10
directors. The Merger Agreement provides that, in accordance with Thrifty
PayLess' request, Rite Aid will take such action as may be required so that
Leonard I. Green, the Chairman of the Thrifty PayLess Board, will be elected
to the Rite Aid Board as of the Effective Time. See "The Merger--Interests of
Certain Persons and Employee Matters."     
 
  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 either (i)
taken at a special meeting of stockholders called by the Rite Aid Board, a
majority of whose members are not Continuing Directors or (ii) approved by
written consent of stockholders, shall require the approval of not less than
75% of the then outstanding Voting Stock.

                       COMPARISON OF STOCKHOLDER RIGHTS
 
GENERAL
 
  Upon consummation of the Merger, the stockholders of Thrifty PayLess, a
Delaware corporation, will become stockholders of Rite Aid, a Delaware
corporation. Differences between Thrifty PayLess's Restated Certificate of
Incorporation (the "Thrifty PayLess Charter") and the Rite Aid Charter to be
in effect as of the Effective Time (the "Rite Aid Restated Charter"), will
result in changes in the rights of stockholders of Thrifty PayLess when they
become stockholders of Rite Aid. The following is a description of certain of
such differences, based on the DGCL as in effect on the date hereof and the
respective charters of Thrifty PayLess and Rite Aid. Certain provisions of the
DGCL and of the Rite Aid Restated Charter could have the effect of making it
more difficult for a third party to acquire, or of discouraging a third party
from attempting to acquire, control of Rite Aid without the approval of the
Rite Aid Board.
 
  The provisions in the Rite Aid Restated Charter relating to the issuance of
preferred stock, dividend rights and the lack of preemptive, subscription or
redemption rights will be substantially similar to the provisions in the
Thrifty PayLess Charter and the existing Rite Aid Charter. See "Description of
Rite Aid Capital Stock--Right Aid Preferred Stock" and "--Rite Aid Common
Stock."
 
  In addition, as Delaware corporations, both Rite Aid and Thrifty PayLess are
subject to the provisions of DGCL Section 203. See "Description of Rite Aid
Capital Stock--Change of Control."
 
VOTING RIGHTS
 
  The Thrifty PayLess Charter currently authorizes A Common Stock, B Common
Stock and preferred stock. Under certain circumstances (as set forth below),
the A Common Stock and B Common Stock will automatically convert into a single
class with identical rights and privileges (a "Conversion"). Pursuant to the
Thrifty PayLess Charter, the Thrifty PayLess Board is comprised of seven
directors. Prior to any Conversion, five of Thrifty PayLess' directors are
elected by the holders of A Common Stock and two are elected by the holders of
B Common Stock (the "Special Voting Rights"). The Rite Aid Restated Charter
has no provision comparable to the Special Voting Rights. Accordingly, the
holders of A Common Stock and B Common Stock who become stockholders of Rite
Aid will no longer have the Special Voting Rights and will be entitled to
voting rights on the same basis as Rite Aid's other stockholders (i.e., one
vote in respect of each share of such stock).
 
  Pursuant to the terms of the Thrifty PayLess Charter, a Conversion will
occur in the event that (i) no "person" (as defined under Rule 13d-3 of the
Exchange Act) owns that number of shares of B Common Stock constituting at
least 75% of the number of shares of A Common Stock owned by GEI, (ii) GEI's
ownership of A Common Stock decreases by more than 50% from 14,139,600 shares
(the number it currently owns), or (iii) the outstanding shares of A Common
Stock represent less than 25% of the outstanding shares of all classes of
Thrifty PayLess Common Stock. In addition, pursuant to the Thrifty PayLess
Charter, shares of A Common Stock may be converted at the option of the holder
thereof into shares of B Common Stock in connection with a sale of such stock,
provided such holder of A Common Stock makes certain required representations
to Thrifty PayLess.
 
OTHER CHARTER PROVISIONS
 
  The Thrifty PayLess Charter does not contain any provisions comparable to
those of the Rite Aid Restated Charter or the existing Rite Aid Charter
relating to the classification of Rite Aid's Board. See "Description of Rite
Aid Capital Stock--Charter Provisions."
 
  In addition, the Rite Aid Charter contains, and the Rite Aid Restated
Charter will contain, provisions that, in certain circumstances, require the
affirmative vote of the holders of shares representing not less than 75% of
the Rite Aid Voting Stock (as defined above). The Thrifty PayLess Charter has
no comparable provision. See "Description of Rite Aid Capital Stock--Charter
Provisions."
 
  The Thrifty PayLess Charter provides that, prior to any Conversion, an
affirmative vote of the holders of a majority of the outstanding shares of B
Common Stock is generally required to approve a sale of substantially
 
                                      64
<PAGE>
 
   
all of Thrifty PayLess' assets, a statutory exchange, or a merger or
consolidation following which the holders of A Common Stock and B Common Stock
together do not have the power to elect a majority of Thrifty PayLess'
directors or in which holders of B Common Stock receive consideration with
materially different rights from those of A Common Stock holders (each a "Sale
Transaction"), provided that no separate class vote of B Common Stock holders
is required if the consideration received by A Common Stock holders and B
Common Stock holders in such transaction is the same (such as in the case of
the Merger, in which holders of A Common Stock and B Common Stock will vote
together as a single class). In addition, the Thrifty PayLess Charter provides
that, prior to any Conversion, the affirmative vote of at least one director
elected by the B Common Stock holders is required to approve dividend
declarations, certain stock redemptions, certain affiliated transactions,
dissolution or liquidation plans, the election to enter into a line of
business other than retail merchandising, certain private placements of
additional shares of Thrifty PayLess Common Stock, issuance of additional
shares of A Common Stock, approval of a Sale Transaction or certain amendments
to Thrifty PayLess' Charter. The Rite Aid Charter does not, and the Rite Aid
Restated Charter will not, contain any comparable provisions.     
   
  In addition, pursuant to the Thrifty PayLess Charter and Bylaws, (i) any
action required or permitted to be taken by Thrifty PayLess' stockholders may
be taken only at a duly called annual or special meeting of Thrifty PayLess
stockholders, rather than by written consent of Thrifty PayLess stockholders,
(ii) a special meeting of Thrifty PayLess' stockholders may only be called by
the Thrifty PayLess Board or Thrifty PayLess' Chief Executive Officer or
President, and (iii) Thrifty PayLess' stockholders must comply with certain
advance notice procedures with regard to the nomination of candidates for
elections as directors or for stockholder proposals to be submitted at
stockholder meetings. The Rite Aid Charter does not, and the Rite Aid Restated
Charter will not, contain comparable provisions.     
 
                                 LEGAL MATTERS
   
  The validity of the Rite Aid Common Stock to be issued to Thrifty PayLess
stockholders pursuant to the Merger will be passed upon by Elliot S. Gerson,
Esq., Senior Vice President and Assistant Chief Legal Counsel of Rite Aid. Mr.
Gerson is the beneficial owner of 13,500 shares of Rite Aid Common Stock. It
is a condition to the consummation of the Merger that Thrifty PayLess and Rite
Aid receive an opinion of Jones Day, counsel to Rite Aid, or Irell & Manella
LLP, counsel to Thrifty PayLess, to the effect that, among other things, the
Merger will constitute a "reorganization" within the meaning of Section 368(a)
of the Code. Partners of the law firm of Irell & Manella LLP own 60,180 shares
of the A Common Stock and 1,007 shares of the B Common Stock of Thrifty
PayLess.     
 
                                    EXPERTS
 
  The consolidated financial statements and schedule of Rite Aid Corporation
and subsidiaries as of March 2, 1996 and March 4, 1995, and for each of the
years in the three-year period ended March 2, 1996, have been incorporated by
reference in this Joint Proxy Statement/Prospectus in reliance upon the
reports 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 refers to a
change in the method of accounting for investments.
 
  With respect to the unaudited interim financial information of Rite Aid
Corporation and subsidiaries for the periods ended June 1, 1996 and August 31,
1996, 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 reports included in
Rite Aid's quarterly reports on Form 10-Q for the quarters ended June 1, 1996
and August 31, 1996, and incorporated by reference herein, states 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
Joint Proxy Statement/Prospectus prepared or certified by the accountants
within the meaning of Sections 7 and 11 of the Securities Act.
 
  The consolidated financial statements and schedule of Thrifty PayLess
Holdings, Inc. and subsidiaries as of October 1, 1995 and October 2, 1994 and
for each of the years in the three-year period ended October 1, 1995, have
been incorporated by reference in this Joint Proxy Statement/Prospectus 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.

  Any stockholder wishing to submit a proposal to Rite Aid for consideration
for inclusion in its proxy statement relating to its 1997 Annual Meeting of
Stockholders must have delivered such proposal to Rite Aid by January 7, 1997.
    
  Thrifty PayLess will hold its 1997 Annual Meeting of Stockholders only if
the Merger has not been consummated. In the event that Thrifty PayLess holds a
1997 Annual Meeting of Stockholders, such meeting will be held during the
spring of 1997, and any proposals from Thrifty PayLess stockholders intended
to be presented thereat and included in Thrifty PayLess' proxy statement
relating thereto must meet the eligibility and other requirements (including
timely submission) of the Commission's rules governing stockholder proposals
and the requirements imposed by Thrifty PayLess' Charter and By-laws.

                                 I. THE MERGER

                                      A-1
<PAGE>
 
the Certificate of Incorporation of the Surviving Corporation until thereafter
amended as provided by law and such Certificate of Incorporation and (ii) the
By-laws of Parent, as in effect immediately prior to the Effective Time, will

and such By-laws. The Merger will have the effects set forth in the DGCL.
 
  1.2. EFFECTIVE TIME. Parent and the Company will cause a certificate of
merger with respect to the Merger (the "Certificate of Merger") to be executed
and filed on the date of the Closing (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 will 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 referred to herein as the "Effective Time".
 
  1.3. CLOSING. The closing (the "Closing") of the transactions contemplated
hereby will take place at 1:00 p.m., New York City time, on the date of the
last to occur of the Special Meetings or, if all of the conditions to the

Certificate of Incorporation and By-laws.
 
  1.5. STOCKHOLDERS' MEETINGS. (a) In order to consummate the Merger, the
Company will, 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 on this Agreement.
The Company will include in the joint proxy statement/prospectus forming a
part of the Registration Statement (the "Proxy Statement/Prospectus") the
recommendation of the Company Board that stockholders of the Company vote in
favor of the adoption of this Agreement.
 
  (b) In order to consummate the Merger, Parent will, 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
considering the adoption of this Agreement and authorizing the issuance of
shares of Parent Common Stock pursuant to the Merger. Parent will include in
the Proxy Statement/Prospectus the recommendation of the Parent Board that
stockholders of Parent vote in favor of the adoption of this Agreement and 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 1.5 is intended to impair compliance with the
fiduciary duties of the Company Board or the Parent Board in respect of any
recommendation to the stockholders of the Company or Parent, as the case may
be, in respect of this Agreement or the transactions contemplated hereby,
provided, however, that nothing in this Article I will limit the respective
rights or obligations of the parties under any other Article hereof.
 
                           II. CONVERSION OF SHARES
 
  2.1. CONVERSION OF SHARES. (a) Subject to Section 2.1(d), each share (other
than shares to be cancelled pursuant to Section 2.1(b) hereof) of Class A
Common Stock, par value $.01 per share, of the Company ("A Common Stock"), and
each share of Class B Common Stock, par value $.01 per share, of the Company
("B Common Stock" and, together with the A Common Stock, the "Company Common
Stock") will, at the
 
                                      A-2
<PAGE>
 
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 0.65 duly
authorized, validly issued, fully paid and nonassessable shares of Parent
Common Stock (the "Exchange Ratio").
 
  (b) 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 or any
direct or indirect wholly owned Subsidiary of Parent or the Company will, at
the Effective Time, be cancelled and retired and will cease to exist and no
Parent Common Stock will be delivered in exchange therefor.
 
  (c) Subject to Section 2.1(d), on and after the Effective Time, holders of
certificates which immediately prior to the Effective Time represented
outstanding shares of Company Common Stock (the "Certificates") will cease to
have any rights as stockholders of the Company, except the right to receive
the consideration set forth in this Article II (the "Merger Consideration")
for each share of Company Common Stock held by them.
 
  (d) Notwithstanding anything in this Agreement to the contrary, no such
share of A Common Stock, the holder of which shall have properly complied with
the provisions of Section 262 of the DGCL as to appraisal rights (a
"Dissenting Share"), will be deemed to be converted into and to represent the
right to receive Parent Common Stock hereunder and the holders of Dissenting
Shares, if any, will be entitled to payment, solely from the Surviving
Corporation, of the appraised value of such Dissenting Shares to the extent
permitted by and in accordance with the provisions of Section 262 of the DGCL;
provided, however, that (i) if any holder of Dissenting Shares, under the
circumstances permitted by the DGCL, affirmatively withdraws his or her demand
for appraisal of such Dissenting Shares, (ii) if any holder fails to establish
his or her entitlement to rights to payment as provided in such Section 262,
or (iii) if neither any holder of Dissenting Shares nor the Surviving
Corporation has filed a petition demanding a determination of the value of all
Dissenting Shares within the time provided in such Section 262, such holder
will forfeit such right to payment for such Dissenting Shares pursuant to such
Section 262 and, as of the later of the Effective Time or the occurrence of
such event, such holder's Certificate formerly representing shares of A Common
Stock will automatically be converted into and represent only the right to
receive shares of Parent Common Stock pursuant to Section 2.1(a), without any
interest thereon, upon surrender of the Certificate or Certificates formerly
representing such shares of A Common Stock. The Company agrees to give Parent
(A) prompt notice of any written demands for appraisal of any Dissenting
Shares, attempted withdrawals of such demands and any other instruments
received by the Company relating to stockholders' rights of appraisal, (B) the
opportunity to direct all negotiations and proceedings with respect to demands
for appraisal under the DGCL, and (C) the sole right to determine whether to
settle any such demand.
 
  2.2. ISSUANCE OF PARENT COMMON STOCK. (a) The manner in which each share of
Company Common Stock (other than shares to be cancelled as set forth in
Section 2.1(c) and other than Dissenting Shares, if any) will be converted
into Parent Common Stock will be as set forth in this Section 2.2.
 
  (b) No certificates or scrip representing fractional shares of Parent Common
Stock will be issued upon the surrender for exchange of Certificates
representing Company Common Stock, no dividend or distribution with respect to
shares of Company Common Stock will be payable on or with respect to any
fractional share and such fractional share interests will 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 will 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 Parent Share Price by (ii) the fractional interest in a
share of Parent Common Stock to which such holder would otherwise be entitled.
For purposes hereof, "Parent Share Price" means the closing sales price per
share of Parent Common Stock on the New York Stock Exchange (the "NYSE") as
reported on the NYSE Composite Tape for the date on which the Effective Time
occurs.
 
  (c) Parent will 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 in
lieu of fractional shares of Parent Common Stock to which holders of shares of
Company Common Stock shall become entitled pursuant to this Article II.
 
                                      A-3
<PAGE>
 
  (d) As soon as reasonably practicable after the Effective Time, the Exchange
Agent will 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 will specify that delivery
will be effected, and risk of loss and title to the Certificates will pass,
only upon delivery of the Certificates to the Exchange Agent and will 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. 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 will be entitled to receive in exchange
therefor the Merger Consideration for each share of Company Common Stock
formerly represented by such Certificate and the Certificate so surrendered
will forthwith be cancelled. If payment of the Merger Consideration is to be
made to a person other than the person in whose name the surrendered
Certificate is registered, it will be a condition of payment that the
Certificate so surrendered is properly endorsed or 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 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 will deliver, in trust,
to the Exchange Agent, for the benefit of the holders of Shares, 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 of Company Common Stock to be converted into Parent Common Stock as
determined by this Article II and, from time to time after the Effective Time,
an amount of cash sufficient to fund the payment of cash in lieu of fractional
shares of Parent Common Stock as provided in Section 2.2(b). As soon as
practicable after the Effective Time, each holder of shares of Company Common
Stock converted into Parent Common Stock, upon surrender to the Exchange Agent
of one or more Certificates for such shares for cancellation, will be entitled
to receive certificates representing the number of shares of Parent Common
Stock into which such shares shall have been converted in the Merger and the
amount, if any, of cash in lieu of fractional shares of Parent Common Stock to
which such holder is entitled under Section 2.2(b) (such amount, the
"Fractional Cash Amount"). 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 of Company Common Stock, at which time all such dividends will be paid.
In no event will the persons entitled to receive such dividends, or any
Fractional Cash Amount, be entitled to receive interest on such dividends or
such Fractional Cash Amount. Notwithstanding the foregoing, neither the
Exchange Agent nor any party hereto will be liable to a holder of shares for
any Parent Common Stock, dividends thereon or Fractional Cash Amount delivered
to a public official pursuant to any applicable abandoned property, escheat or
similar law.
 
  (f)  At any time following six months after the Effective Time, the
Surviving Corporation will 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 been disbursed to holders of Certificates,
and thereafter such holders will be entitled to look only to the Surviving
Corporation (subject to abandoned property, escheat or other similar laws)
with respect to the Merger Consideration payable or issuable upon due
surrender of their Certificates, without any interest thereon.
   
  2.3. TREATMENT OF STOCK OPTIONS. (a) Except as set forth in Section 2.3(a)
of the Company Disclosure Schedule, the Company hereby covenants to take all
actions necessary so that, effective as of the Effective Time, each option or
warrant granted by the Company to purchase shares of Company Common Stock that
is outstanding and unexercised immediately prior thereto (the "Company Stock
Options"), whether or not then exercisable, will be disposed of to the Company
and will cease to represent a right to acquire shares of Company Common Stock
and will be converted automatically into a right to receive an amount of cash
equal to (i) 65% of the Parent Share Price minus the exercise price per share
under the applicable Company Stock Options, times (ii) the number of shares of
Company Common Stock purchasable upon exercise of such Company Stock Options.
    
                                      A-4
<PAGE>
 
   
  (b) Except as specifically set forth in Section 2.3(b) of the Company
Disclosure Schedule, the Company covenants to take all actions necessary so
that, effective as of the Effective Time, the Company's 1992 Management Equity
Plan, its 1994 Management Equity Plan, its Non-Employee Director Stock Option
Plan and its Deferred Compensation Plan for Non-Management Directors
(collectively, the "Option Plans") 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 are deleted. Furthermore, except as specifically set forth in
Sections 2.3(a) and (b) of the Company Disclosure Schedule, the Company will
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 will have any right
thereunder to acquire any equity securities of Parent, the Company, the
Surviving Corporation or any Subsidiary of any of the foregoing.     
 
  2.4. STOCK TRANSFER BOOKS. At the Effective Time, the stock transfer books
of the Company will be closed and there will be no further registration of
transfers of shares of Company Common Stock on the records of the Company. If,
after the Effective Time, Certificates formerly representing shares of Company
Common Stock are presented to the Surviving Corporation, they will be
cancelled and exchanged for cash or certificates representing Parent Common
Stock pursuant to this Article II.
 
              III. REPRESENTATIONS AND WARRANTIES OF THE COMPANY
 
  The Company represents and warrants to Parent as follows (which
representations and warranties are qualified in their entirety by the Company
Disclosure Schedule, whether or not the specific representation or warranty is
so qualified):
 
  3.1. ORGANIZATION. (a) The Company and each of 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. The Company and each of its Subsidiaries
are duly qualified or licensed to do business and in good standing in each
jurisdiction in which the property owned, leased or operated by them or the
nature of the business conducted by them 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. 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) 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 or group of entities,
taken as a whole, or materially impairs the ability of such entity or group of
entities, taken as a whole, to perform its obligations hereunder or the
Stockholder Agreements or the transactions contemplated hereby or thereby. If
"material adverse effect" is used with respect to more than one entity, it
will mean such events, changes or effects with respect to all such entities
taken as a whole. If "material adverse effect" is used with respect to the
Company or Parent, it will mean such events, changes or effects with respect
to the Company or Parent, as the case may be, and its respective consolidated
Subsidiaries, 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.
 
                                      A-5

  3.2. CAPITALIZATION. (a) The authorized capital stock of the Company

number of issued and outstanding, treasury and reserved shares of capital
stock of the Company and shares of capital stock subject to Company Stock
Options was as set forth in Section 3.2 of the Company Disclosure Schedule.
All the outstanding shares of the Company's capital stock are, and all shares
which may be issued pursuant to the Company Stock Option Plans will be, when
issued in accordance with the respective terms thereof, duly authorized,
validly issued, fully paid and non-assessable. There are no bonds, debentures,
notes or other indebtedness having voting rights (or convertible into
securities having such rights) ("Voting Debt") of the Company or any of its
Subsidiaries issued and outstanding. Except as set forth above and except for
the transactions contemplated by this Agreement, as of the date hereof, (i)
there are no shares of capital stock of the Company 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 the Company or any of its Subsidiaries,
obligating the Company or any of its Subsidiaries to issue, transfer or sell
or cause to be issued, transferred or sold any shares of capital stock or
Voting Debt of, or other equity interest in, the Company or any of its
Subsidiaries or securities convertible into or exchangeable for such shares or
equity interests or obligations of the Company 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.
Except as set forth in Section 3.2 of the Company Disclosure Schedule, (A)

defined in Section 8.4) of the Company or to provide funds to make any
investment (in the form of a loan, capital contribution or otherwise) in any
Subsidiary or any other entity and (B) following the Merger, neither the
Company nor any of its Subsidiaries will have any obligation to issue,
transfer or sell any shares of its capital stock pursuant to any employee
benefit plan or otherwise.
 
  (b) Except as disclosed in Section 3.2(b) of the Company Disclosure
Schedule, all of the outstanding shares of capital stock of each of the
Subsidiaries are owned beneficially and of record solely by the Company,
directly or indirectly, and all such shares have been validly issued and are
fully paid and nonassessable and are so owned by either the Company or one of
its Subsidiaries free and clear of all liens, charges, security interests,
options, claims or encumbrances of any nature whatsoever.
 
  (c) Except as disclosed in Section 3.2(c) of the Company Disclosure Schedule
and except for the Stockholder Agreements, there are no voting trusts or other
agreements or understandings to which the Company or any of its Subsidiaries
is a party with respect to the voting of the capital stock of the Company or
any of the Subsidiaries. The Company agrees that, upon the consummation of the
Merger, the stockholder agreement disclosed in Section 3.2(c) of the Company
Disclosure Schedule (the "Existing Stockholder Agreement") will, without
further action, terminate. None of the Company or its Subsidiaries is required
to redeem, repurchase or otherwise acquire shares of capital stock of the
Company, or any of its Subsidiaries, respectively, as a result of the
transactions contemplated by this Agreement.

outstanding will not exceed the number set forth in Section 3.2 of the Company
Disclosure Schedule.
 
  3.3. CORPORATE AUTHORIZATION; VALIDITY OF AGREEMENT; COMPANY ACTION. (a) The
Company has full corporate power and authority to execute and deliver this
Agreement and, subject to obtaining the Company Stockholder Approval, to
consummate the transactions contemplated hereby. The execution, delivery and
performance by the Company of this Agreement and the consummation by the
Company of the transactions contemplated hereby, have been duly and validly
authorized by the Company Board and, except in the case of
 
                                      A-6
<PAGE>
 
this Agreement for obtaining the Company Stockholder Approval, no other
corporate action or proceedings on the part of the Company are necessary to
authorize the execution and delivery by the Company of this Agreement and the
consummation by it of the transactions contemplated hereby. This Agreement has
been duly executed and delivered by the Company and, assuming this Agreement
constitutes a valid and binding obligation of Parent, constitutes a valid and
binding obligation of the Company enforceable against the Company in
accordance with its terms, except (i) as may be subject to applicable
bankruptcy, insolvency or other similar laws, now or hereafter in effect,
affecting creditors' rights generally and (ii) that 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.
 
  (b) The Company Board has duly and validly approved and taken all corporate
action required to be taken by the Company Board for the consummation of the
transactions as contemplated by this Agreement (including the Merger, the
transactions contemplated by the Stockholder Agreements and the termination of
the Existing Stockholder Agreement), including all actions necessary to
approve such transactions as contemplated by the provisions of Section
203(a)(1) of the DGCL.
 
  3.4. CONSENTS AND APPROVALS; NO VIOLATIONS. Except as disclosed in Section
3.4 of the Company Disclosure Schedule, and except for filings, permits,
authorizations, consents and approvals as may be required under, and other
applicable requirements of, the Securities Exchange Act of 1934, as amended
(the "Exchange Act"), the DGCL and the Hart-Scott-Rodino Antitrust

of Merger as required by the DGCL, none of the execution, delivery or
performance of this Agreement nor the consummation by the Company of the
transactions contemplated hereby nor compliance by the Company 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 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), (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
(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 $1,000,000 (each 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.
 
  3.5. SEC REPORTS AND FINANCIAL STATEMENTS. The Company has filed with the
Securities and Exchange Commission (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 the Company
or any of its Subsidiaries since January 1, 1993 under the Exchange Act or the
Securities Act of 1933 (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 prior to the date of this Agreement, the Company SEC
Documents, including 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 has
been prepared from, and
 
                                      A-7
<PAGE>
 
is in accordance with, the books and records of the Company and/or its
consolidated Subsidiaries, complies in all material respects with applicable
accounting requirements and with the published rules and regulations of the
SEC with respect thereto, has 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 presents 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.
 
  3.6. ABSENCE OF CERTAIN CHANGES. Except to the extent disclosed in the
Company SEC Documents filed prior to October 10, 1996 (the "Company Filed SEC
Documents") or as otherwise disclosed to Parent in Section 3.6 of the Company
Disclosure Schedule, from July 1, 1996 (the "Company Strike Date") 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 the Company Strike Date through the date
of this Agreement, there have not occurred (a) 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, (b) 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 (c) any material
change by the Company or any of its Subsidiaries in accounting principles or
methods, except insofar as may be required by a change in GAAP. Except as set
forth on Schedule 3.6 of the Company Disclosure Schedule, from the Company
Strike Date through the date of this Agreement, neither the Company nor any of
its Subsidiaries has taken any of the actions that would have been prohibited
by Section 5.1(a)-(c) had Section 5.1(a)-(c) applied to the Company and its
Subsidiaries from and after the Company Strike Date.
 
  3.7. NO UNDISCLOSED LIABILITIES. Except (a) to the extent disclosed in the
Company Filed SEC Documents and (b) for liabilities and obligations incurred
in the ordinary course of business consistent with past practice, since the
Company Strike Date, neither the Company nor any of its Subsidiaries has
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 consolidated balance sheet of
the Company and its Subsidiaries as of the Company Strike Date. Section 3.7 of
the Company Disclosure Schedule sets forth each instrument evidencing
indebtedness or other obligations of the Company or any of 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
other obligations, 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, the Stockholder Agreements or
the other transactions contemplated hereby or thereby.
 
  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 any party to the
Stockholder Agreements specifically for inclusion in the Proxy
Statement/Prospectus. None of the information supplied by the Company
specifically for inclusion or incorporation by reference in the Proxy
Statement/Prospectus 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.
 
                                      A-8
<PAGE>
 
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.

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

  (c) With respect to each Benefit Plan, except as disclosed on Schedule
3.9(c) of the Company Disclosure Schedule or as would not have a material
adverse effect on the Company and its Subsidiaries, (i) if intended to qualify

such plan so qualifies and its trust is exempt from taxation under Section
501(a) of the Code; (ii) to the Company's knowledge such plan has been
administered in accordance with its terms and applicable law; (iii) to the
Company's knowledge no breaches of fiduciary duty have occurred; (iv) no
disputes are pending, or, to the knowledge of the Company, threatened; (v)

Code or ERISA exists; and (vii) all contributions and premiums due (including
any extensions for such contributions and premiums) have been made in full.

not 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); (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 involving
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
 
                                      A-9
<PAGE>
 
amended or terminated by the Company or any of its Subsidiaries at any time
with respect to such former or current employees.
 
  (g) With respect to each Benefit Plan that is intended to provide special
tax treatment to participants (including Sections 79, 105, 106, 125, 127 and
129 of the Code), to the Company's knowledge, such Benefit Plan has satisfied
all of the material requirements for the receipt of such special tax treatment
since September 29, 1992.
 
  (h) Except as specifically set forth in Section 3.9(h) of the Company
Disclosure Schedule or Section 2.3 hereof, the consummation of the
transactions contemplated by this Agreement will not (i) entitle any
individual to severance pay, other benefits or any tax "gross-up" payments
with respect to the imposition of any tax pursuant to Section 4999 of the Code
or accelerate the time of payment or vesting, or 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 nor, to the Company's knowledge, any ERISA
Affiliate nor any "administrator" as that term is defined in Section 3(16) of
ERISA, has any material 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
Schedule, there is no Benefit Plan that is a "multiemployer plan," as such
term is defined in Section 3(37) of ERISA, or which is covered by Section 4063
or 4064 of ERISA.
 
  (k) With respect to each Benefit Plan except Plans in which employees of
Parent or its Affiliates do not participate and except Multiemployer Plans
from which the Company has withdrawn, the Company has delivered or made
available to Parent accurate and complete (with de minimis omissions) copies
of all plan texts, summary plan descriptions, summaries of material
modifications, trust agreements and other related agreements including all
amendments to the foregoing; the two most recent annual reports; the most
recent annual and periodic accounting of plan assets; the most recent
determination letter received from the United States Internal Revenue Service
(the "Service"); and the two most recent actuarial reports, to the extent any
of the foregoing may be applicable to a particular Benefit Plan.
 
  (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, 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
agreements (including change of control agreements, severance agreements,
retirement agreements, stock option or purchase agreements, medical or death
benefit agreements) maintained by the Company or an ERISA Affiliate or with
respect to which the Company or any of its Subsidiaries has a material
liability 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 "Director Plans"). Neither the Company nor any ERISA Affiliate has any
formal plan or commitment, whether or not legally binding, to create any
Director Plan or modify or change any existing Director Plan that would affect
any director or former director of the Company or any ERISA Affiliate.
 
  3.10. LITIGATION. Except to the extent disclosed in the Company Filed SEC
Documents or in Section 3.10 of the Company Disclosure Schedule, there is no
suit, claim, action, proceeding or investigation pending or,
 
                                     A-10

Disclosure Schedule, each Company Agreement is a valid, binding and
enforceable obligation of the Company or, as applicable, its Subsidiary and,
to the Company's knowledge, the other parties thereto and is in full force and

Subsidiaries, as the case may be.

  3.18. INSURANCE. As of the date hereof, the Company and each of its
Subsidiaries are insured by insurers, reasonably believed by the Company to be
of recognized financial responsibility and solvency, against such losses and
risks and in such amounts as are customary in the businesses in which they are
respectively engaged. All material policies of insurance and fidelity or
surety bonds are in full force and effect. Descriptions of these policies and
related liability coverage have been previously provided to Parent. These
claims, individually or in the aggregate, would not have a material adverse
effect on the Company and its Subsidiaries. All necessary notifications of
claims have been made to insurance carriers other than those which will not

discrimination, occupational safety and health, interstate commerce and
antitrust laws, except where the failure to so comply would not have a
material adverse effect on the Company and its Subsidiaries. The Company, with
respect to each Company store location, has all permits and licenses
(including, without limitation, pharmaceutical and liquor licenses and
permits) necessary to carry on the business being conducted at each store
 
                                     A-13
<PAGE>
 
location, except where the failure to have such permit or license would not
have a material adverse effect on the Company and its Subsidiaries.
 
  3.21. VOTE REQUIRED. The affirmative vote of the holders of a majority of
the shares of A Common Stock and B Common Stock, voting together as a single
class, is the only vote of the holders of any class or series of the Company's
capital stock necessary to approve the Merger ("Company Stockholder
Approval").
 
  3.22. BROKERS. No broker, investment banker, financial advisor or other
person, other than Goldman, Sachs & Co. ("GS") and Leonard Green & Partners,
the fees and expenses of which will be paid by the Company, is entitled to any

connection with the transactions contemplated by this Agreement or the

Company or any Subsidiary thereof. The Company has furnished or made available

  3.23. OPINION OF FINANCIAL ADVISOR. The Company has received the written

                 IV. REPRESENTATIONS AND WARRANTIES OF PARENT
 
  Parent represents and warrants to the Company as follows:
 
  4.1. ORGANIZATION. Parent and each Significant Parent 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. Exhibit 21.1 to Parent's last Annual Report on Form 10-K filed
with the SEC includes all the subsidiaries of Parent which as of the date of
this Agreement are "significant subsidiaries" within the meaning of Rule 1-02
of Regulation S-X of the SEC (such Parent Subsidiaries, "Significant Parent
Subs").
 
  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 preferred shares,
par value $1.00 per share (the "Parent Preferred Stock"). As of October 10,
1996 (the "Parent Measurement Date"), (i) 90,441,000 shares of Parent Common
Stock were issued and outstanding, (ii) no shares of Parent Preferred Stock
were issued and outstanding, (iii) 6,532,169 shares of Parent Common Stock
were issued and held in the treasury of Parent, and (iv) 13,397,200 shares of
Parent Common Stock were reserved for issuance under Parent's 1990 Omnibus
Stock Incentive Plan (the "Parent Plan") and Parent's 6.75% Zero Coupon
Convertible Subordinated Notes due July 24, 2006 ("Parent's Zero Coupon
Notes"). All of the outstanding shares of Parent's capital stock are, and all
shares which may be issued pursuant to the exercise of outstanding options or
pursuant to the Parent Plan or Parent's Zero Coupon Notes will be, when issued
in accordance with the respective terms thereof, duly authorized, validly
issued, fully paid and non-assessable. Except for Parent's Zero Coupon Notes,
there are no bonds, debentures, notes or other indebtedness having voting
rights (or convertible into securities having such rights) ("Parent Voting
Debt") of Parent or any of its Subsidiaries issued and outstanding. Except as
set forth above, and except as set forth in Section 4.2 of the Disclosure
Schedule delivered to the Company on or prior to the date hereof (the "Parent
Disclosure Schedule") and except for transactions contemplated by this
Agreement, as of the Parent Measurement Date, (i) there are no shares of
capital stock of Parent authorized, issued or outstanding and (ii)
 
                                     A-14
<PAGE>
 
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 any other
class of the capital stock of Parent or any Subsidiary or Affiliate of Parent
or to provide funds to make any investment (in the form of a loan, capital
contribution or otherwise) in any Subsidiary or any other entity.
 
  (b) All of the outstanding shares of capital stock of each of the Parent
Significant Subs are owned beneficially and of record solely by Parent,
directly or indirectly, and all such shares have been validly issued and are
fully paid.
 
  (c) Except for the Stockholder Agreements, there are no voting trusts or
other agreements or understandings to which Parent or any of its Subsidiaries
is a party with respect to the voting of the capital stock of Parent or its
Subsidiaries. None of Parent or its Subsidiaries is required to redeem,
repurchase or otherwise acquire shares of capital stock of Parent, or any of
its Subsidiaries, respectively, as a result of the transactions contemplated
by this Agreement.
 
  4.3. CORPORATE AUTHORIZATION; VALIDITY OF AGREEMENT; NECESSARY
ACTION. (a) Parent has full corporate power and authority to execute and
deliver this Agreement and the Stockholder Agreements and, subject in the case
of this Agreement to obtaining any necessary approval of Parent's stockholders
as contemplated by Section 1.5(b) hereof with respect to the adoption of this
Agreement and the issuance of Parent Common Stock pursuant to the Merger
("Parent Stockholder Approval"), to consummate the transactions contemplated
hereby and thereby. The execution, delivery and performance by Parent of this
Agreement and the Stockholder Agreements and the consummation by Parent of the
transactions contemplated hereby and thereby have been duly and validly
authorized by the Parent Board and, except for the Parent Stockholder
Approval, no other corporate action or proceedings on the part of Parent are
necessary to authorize the execution and delivery by Parent of this Agreement
and the Stockholder Agreements and the consummation by Parent of the
transactions contemplated hereby and thereby. This Agreement and the
Stockholder Agreements have been duly executed and delivered by Parent and,
assuming this Agreement and the Stockholder Agreements constitute the valid
and binding obligation of the Company, constitutes the valid and binding
obligation of Parent enforceable against Parent in accordance with their
terms, except (i) as may be subject to applicable bankruptcy, insolvency or
other similar laws, now or hereafter in effect, affecting creditors' rights
generally and (ii) that 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. The shares of Parent Common Stock issued pursuant to the Merger will
be duly authorized, validly issued, fully paid and nonassessable and not
subject to preemptive rights.
 
  (b) The Parent Board has duly and validly approved and taken all corporate
action required to be taken by the Parent Board for the consummation by Parent
of the transactions contemplated by this Agreement (including without
limitation the Merger and the Stockholder Agreements).
 
  4.4. CONSENTS AND APPROVALS; NO VIOLATIONS. Except for filings, permits,
authorizations, consents and approvals as may be required under, and other
applicable requirements of, the Exchange Act, 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, none of the execution, delivery or performance of this
Agreement and the Stockholder Agreements by Parent nor the consummation by
Parent of the transactions contemplated hereby nor compliance by Parent 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, (ii)
require
 
                                     A-15
<PAGE>
 
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), (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 and which either
has a term of more than one year or involves the payment or receipt of money
in excess of $1,000,000 (each a "Parent Agreement"), 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 violations, breaches or defaults
which would not, individually or in the aggregate, have a material adverse
effect on Parent and its Subsidiaries.
 
  4.5. SEC REPORTS AND FINANCIAL STATEMENTS. Parent has filed with 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 January 1, 1993, under the Exchange Act
or the Securities Act (as such documents have been amended since the time of
their filing, collectively, the "Parent SEC Documents"). As of their
respective dates or, if amended, as of the date of the last such amendment
filed prior to the date of this Agreement, the Parent SEC Documents, including
without limitation any financial statements or schedules included therein, (i)
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 (ii) 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 Parent SEC Documents has
been prepared from, and are in accordance with, the books and records of
Parent and/or its consolidated Subsidiaries, complies in all material respects
with applicable accounting requirements and with the published rules and
regulations of the SEC with respect thereto, has been prepared in accordance
with GAAP applied on a consistent basis during the periods involved (except as
may be indicated in the notes thereto) and fairly presents 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
Parent and its consolidated Subsidiaries as at the dates thereof or for the
periods presented therein.
 
  4.6. ABSENCE OF CERTAIN CHANGES. Except to the extent disclosed in the
Parent SEC Documents filed prior to October 10, 1996 (the "Parent Filed SEC
Documents"), from August 1, 1996 (the "Parent Strike Date") through the date
of this Agreement, Parent and its Subsidiaries have conducted their respective
businesses in the ordinary course of business consistent with past practice.
From the Parent Strike Date through the date of this Agreement, there have 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 Parent 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
Parent or of any of its Subsidiaries other than regular quarterly cash
dividends or dividends paid by wholly owned Subsidiaries, or (iii) any change
by Parent or any of its Subsidiaries in accounting principles or methods,
except insofar as may be required by a change in GAAP. No indebtedness or
other obligations of Parent or any of its Subsidiaries 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 other obligations, 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, the Stockholder Agreements or the other transactions
contemplated hereby or thereby, except for such of the foregoing as would not,
individually or in the aggregate, have a material adverse effect on Parent and
its Subsidiaries.
 
  4.7. NO UNDISCLOSED LIABILITIES. Except (a) to the extent disclosed in the
Parent Filed SEC Documents and (b) for liabilities and obligations incurred in
the ordinary course of business consistent with past practice,
 
                                     A-16
<PAGE>
 
during the period from the Parent Strike Date through the date of this
Agreement, neither Parent nor any of its Subsidiaries has incurred any
liabilities or obligations of any nature, whether or not accrued, contingent
or otherwise, including any Environmental Liabilities and Costs or liabilities
under any employee retirement benefit plan or welfare benefit plan (as those
terms are used in ERISA) of Parent or any Subsidiary of Parent, that have, or
would be reasonably likely to have, a material adverse effect on Parent and
its Subsidiaries or would be required to be reflected or reserved against on a
consolidated balance sheet of Parent and its Subsidiaries (including the notes
thereto) prepared in accordance with GAAP as applied in preparing the
consolidated balance sheet of Parent and its Subsidiaries as of the Parent
Strike Date.
 
  4.8. INFORMATION IN PROXY STATEMENT/PROSPECTUS. The Registration Statement
(or any amendment thereof or supplement thereto) will, at the date it is filed
with the SEC and as of the date it becomes effective, and the Proxy
Statement/Prospectus (or any amendment thereof or supplement thereto) at the
date mailed to Parent's and the Company's stockholders 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 were made, not misleading, provided, however, that no
representation is made by Parent with respect to statements made therein based
on information supplied by the Company or any party to the Stockholder
Agreements other than Parent and the Individual Stockholders (as defined
therein) specifically for inclusion in the Registration Statement or the Proxy
Statement/Prospectus. None of the information supplied by Parent or such
Individual Stockholders specifically for inclusion or incorporation by
reference in the Proxy Statement/Prospectus will, at the date mailed to the
Company's and Parent's stockholders or 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 were made,
not misleading. Subject to the proviso set forth in the second preceding
sentence, the Registration Statement and the Proxy Statement/Prospectus will
comply in all material respects with the provisions of the Securities Act and
Exchange Act, respectively, and the rules and regulations thereunder.
 
  4.9. LITIGATION. Except to the extent disclosed in the Parent Filed SEC
Documents, as of the date of this Agreement, there is no suit, claim, action,
proceeding or investigation pending or, to the knowledge of Parent, overtly
threatened against or affecting, Parent or any of its Subsidiaries, which,
individually or in the aggregate, is reasonably likely to have a material
adverse effect on Parent and its Subsidiaries or would, or would be reasonably
likely to, materially impair the ability of Parent to consummate the Merger or
the other transactions contemplated hereby.

  (as such term is defined in Section 341(f)(4) of the Code) owned by Parent
  or any of its Subsidiaries.
 
  4.11. COMPLIANCE WITH LAW. Except as disclosed in the Parent Filed SEC
Documents, Parent and its Subsidiaries have complied in all material respects

  4.12. NO DEFAULT. The business of Parent and each of its Subsidiaries is not
being conducted in default or violation of any term, condition or provision of
(a) its respective certificate of incorporation or by-laws or similar
organizational documents, (b) any lease, license, contract, agreement or other
instrument or obligation to which Parent or any of its Subsidiaries is a party

  4.15. CONTRACTS. Each Parent Agreement is a valid, binding and enforceable
obligation of Parent or, as applicable, its Subsidiaries and, to Parent's
knowledge, the other parties thereto and is in full force and effect, except

effect would not have a material adverse effect on Parent and its
Subsidiaries, and there are no defaults thereunder by Parent or its
Subsidiaries or, to the knowledge of Parent, by any other party thereto that
would have a material adverse effect on Parent and its Subsidiaries. Neither
Parent nor any Subsidiary of Parent is a party to any agreement that expressly

any geographic area or during any period of time which would have a material
adverse effect on Parent or its Subsidiaries.

including (as applicable) title or leaseholds thereto, of Parent and its
Subsidiaries, taken as a whole, are sufficient to permit Parent and its
Subsidiaries to conduct their respective businesses as currently being
conducted with only such exceptions as would not have a material adverse
effect on Parent and its Subsidiaries. All real property owned by Parent or
any of its Subsidiaries is so owned free and clear of all liens, charges,
security interests, options, claims, mortgages, pledges, easements, rights-of-
way or other encumbrances and restrictions of any nature whatsoever, except as

to the contrary, except for such of the foregoing as would not have a material
adverse effect on Parent and its Subsidiaries.
 
  4.18. LABOR RELATIONS. There is no labor strike, slowdown or work stoppage
or lockout against Parent or any of its Subsidiaries, there is no unfair labor
practice charge or complaint against or pending before the NLRB which if
decided adversely could have a material adverse effect on Parent and its
Subsidiaries and there is no representation claim or petition pending before
the NLRB and no question concerning representation has been raised with

foregoing as would not have a material adverse effect on Parent and its
Subsidiaries.
 
  4.19. INSURANCE. As of the date hereof, Parent and each of its Subsidiaries
are insured by insurers, reasonably believed by Parent to be of recognized
financial responsibility and solvency, against such losses and risks and in
such amounts as are customary in the businesses in which they are respectively
engaged. All material policies of insurance and fidelity or surety bonds are
in full force and effect.
 
  4.20. TRANSACTIONS WITH AFFILIATES. Except as disclosed in the Parent Filed
SEC Documents, since January 1, 1993, there have been no transactions,

fee or commission in connection with the transactions contemplated by this
Agreement or the Stockholder Agreements based upon arrangements made by or on
behalf of Parent or any Subsidiary thereof. Parent has furnished to the
Company true and complete copies of all agreements under which any such fees
or expenses are payable and all indemnification and other agreements related
to the engagement of the persons to whom such fees are payable.

  in Section 5.5);
 
    (l) neither the Company nor any of its Subsidiaries may engage in any

  5.2. ACCESS TO INFORMATION. (a) Except to the extent that such party
determines in good faith that so doing would constitute a breach of contract
(other than an Acquisition Agreement) or a violation of law, each of the
Company and Parent will (and will cause each of its respective Subsidiaries
to) afford to the officers, employees, accountants, counsel, financing sources
and other representatives of the other, access, during normal business hours,
during the period prior to the Effective Time, to all of its and its
respective Subsidiaries' properties, books, contracts, commitments, records
(including any Tax Returns or other Tax related information pertaining to
Parent, the Company or their respective Subsidiaries) and executive,
management and operational employees, and, during such period, each of the
Company and Parent will (and will cause each of its Subsidiaries to) furnish
promptly to the other (i) a copy of each report, schedule, registration
statement and other document filed or received by it during such period
pursuant to the requirements of federal securities laws and (ii) all other
information concerning its business, properties and personnel as Parent may
reasonably request (including any Tax Returns or other Tax related information
pertaining to it and its Subsidiaries). Parent will hold any such information
which is nonpublic in confidence in accordance with the provisions of the
existing confidentiality agreement between the Company and Parent, dated as of
October 3, 1996 (the "Company Confidentiality Agreement"). The Company will
hold such information which is nonpublic in confidence in accordance with the
provisions of the existing confidentiality agreement between the Company and
Parent, dated as of October 3, 1996 (the "Parent Confidentiality Agreement"
and, together with the Company Confidentiality Agreement, the "Confidentiality
Agreements").
 
  (b) Without limiting the generality or effect of the foregoing, in
anticipation of the Closing, at the request of Parent, the Company will afford
Parent and its representatives access, during normal business hours and
without undue disruption to the Company's and its Subsidiaries' operations, to
Company's and its Subsidiaries' stores and other facilities to permit Parent
to install wiring, satellite dishes and other equipment thereat designed to
permit Parent to integrate the operations of the Company and its Subsidiaries
into the operations of Parent and its Subsidiaries after the Merger. All such
actions will be at the sole cost and expense of Parent and, if this Agreement
is terminated, Parent will remove any equipment so installed and repair any
damage which may be incurred therein and otherwise restore the Company's
properties to their condition prior to such installations. Parent will
indemnify, defend and hold harmless the Company and each of its Subsidiaries
from and against any and all loss, cost, damage, expense (including attorneys'
costs and expenses) in respect of any third-party claim arising out of any of
the activities of Parent referred to in this Section 5.2(b).
 
  5.3. CONSENTS AND APPROVALS. (a) Each of the Company and Parent will take
all reasonable actions necessary to file as soon as practicable notifications
under the HSR Act and to respond as promptly as practicable to any inquiries
received from the Federal Trade Commission and the Antitrust Division of the
Department of Justice for additional information or documentation and to
respond as promptly as practicable to all inquiries and requests received from
any State Attorney General or other Governmental Entity in connection with
antitrust matters.
 
                                     A-22
<PAGE>
 
  (b) Each of Parent and the Company will, and each will cause each of its
respective Subsidiaries to, (i) cooperate with one another to prepare, as soon
as practicable, all filings and other presentations in connection with seeking
any regulatory approval from a Governmental Entity, exemption or other
authorization necessary to consummate the transactions contemplated by this
Agreement, (ii) prosecute such filings and other presentations with diligence,
(iii) diligently oppose any objections to, appeals from or petitions to
reconsider or reopen any such approval by persons not party to this Agreement,
(iv) diligently defend any action, suit or proceeding seeking equitable or
monetary relief in respect of this Agreement or the Stockholder Agreements or
any of the transactions contemplated hereby or thereby, and (v) take all such
further action as in Parent's and the Company's respective judgment reasonably
may facilitate obtaining any final order or orders approving such transactions
consistent with this Agreement, provided, however, that nothing in this
Section 5.3 or any other provision of this Agreement will require Parent or
any Subsidiary of Parent to agree to any divestiture, hold-separate or other
limitation in connection with the Merger or any other transaction contemplated
hereby. Subject to the proviso to the immediately preceding sentence, each of
the Company and Parent will and will cause its respective Subsidiaries to (A)
take all reasonable actions necessary to comply promptly with all legal
requirements (which actions will include without limitation furnishing all
information in connection with approvals of or filings with any Governmental
Entity including without limitation any schedule or report 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 and (B) 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, the Company or any of their Subsidiaries in
connection with the Merger or the taking of any action contemplated thereby or
by this Agreement or the Stockholder Agreements.
 
  5.4. EMPLOYEE BENEFITS. Effective from and after the Effective Time, the
Surviving Corporation and its Subsidiaries will provide to employees of the
Company the severance and other benefits set forth in Section 5.4 of the
Company Disclosure Schedule.
 
  5.5. 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 cause their
respective officers, directors, investment bankers, attorneys, accountants and
other agents not to, directly or indirectly: (i) initiate, solicit or
encourage (including by way of furnishing information), or take any other
similar action to facilitate the making of, any offer or proposal which
constitutes or is reasonably likely to lead to, any Takeover Proposal 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 person (other than Parent, any of its Affiliates or representatives)
relating to any Takeover Proposal; provided, however, that if the Company
Board determines in good faith, having received and considered the advice of
outside counsel, that it is necessary to do so in order to comply with its
fiduciary duties to the Company's stockholders under applicable law, the
Company may, in response to a Takeover Proposal which was not solicited by it
or which did not otherwise result from a breach of this Section 5.5, and
subject to compliance with all other provisions of this Section 5.5, (x)
furnish information with respect to the Company and its Subsidiaries to any
person pursuant to a customary confidentiality agreement (as determined by the
Company after consultation with its outside counsel) and (y) participate in
negotiations regarding such Takeover Proposal. For purposes of this Agreement,
"Takeover Proposal" means any inquiry, proposal or offer from any person
relating to any direct or indirect acquisition or purchase of 14.9% or more of
the assets of the Company and its Subsidiaries or 14.9% or more of any class
of equity securities of the Company or any of its Subsidiaries, any tender
offer or exchange offer that if consummated would result in any person
beneficially owning 14.9% or more of any class of equity securities of the
Company or any of its Subsidiaries, or any merger, consolidation, business
combination, recapitalization, liquidation, dissolution or similar transaction
involving the Company or any of its Subsidiaries, other than the transactions
contemplated by this Agreement.

<PAGE>
 
  (b) Except as expressly permitted by this Section 5.5, neither the Company
Board nor any committee thereof may (i) withdraw or modify, or propose
publicly to withdraw or modify, in a manner adverse to Parent, the approval or
recommendation by such Company Board or such committee of the Merger or this
Agreement, (ii) approve or recommend, or propose publicly to approve or
recommend, any Takeover Proposal (other than the Merger), or (iii) cause the
Company to enter into any letter of intent, agreement in principle,
acquisition agreement or other similar agreement (each, an "Acquisition
Agreement") related to any Takeover Proposal. Notwithstanding the foregoing,
in the event that prior to the adoption of this Agreement by the holders of
the Company Common Stock, the Company Board determines in good faith, after it
has received a Superior Proposal and having received and considered advice of
outside counsel, that it is necessary to do so in order to comply with its
fiduciary duties to the Company's stockholders under applicable law, the
Company Board may (subject to this and the other provisions hereof) withdraw
or modify its approval or recommendation of the Merger or this Agreement, but
in any such case only at a time that is after the fifth business day following
Parent's receipt of written notice advising Parent that the Company Board has
received a Superior Proposal, specifying the material terms and conditions of
such Company Superior Proposal and identifying the person making such Superior
Proposal. For purposes of this Agreement, a "Superior Proposal" means any
proposal made by a third party to acquire, directly or indirectly, for
consideration consisting of cash and/or securities, more than 50% of the
combined voting power of the shares of Company Common Stock then outstanding
or all or substantially all the assets of the Company and otherwise on terms
which the Company Board determines in its good faith judgment (having received
and considered the advice of a financial advisor of nationally recognized
reputation) to be more favorable to the Company's stockholders than the Merger
and for which financing, to the extent required, is then committed or which,
in the good faith judgment of the Company Board, is reasonably capable of
being obtained by such third party.
 
  (c) In addition to the obligations of the Company set forth in Section 5.5
(a) and (b), the Company will immediately advise Parent orally and in writing
of any request for information or of any Takeover Proposal that comes to the
attention of any of its officers or directors, the material terms and
conditions of such request or Takeover Proposal and the identity of the person
making such request or Takeover Proposal. The Company will keep Parent
reasonably informed of the status and details (including amendments or
proposed amendments) of any such request or Takeover Proposal.
 
  (d) Nothing contained in this Section 5.5 will prohibit the Company from
taking and disclosing to its stockholders a position contemplated by Rule 14e-
2(a) promulgated under the Exchange Act or from making any disclosure that the
Company's Board, having received and considered the advice of outside counsel,
determines in good faith that the failure so to disclose would be inconsistent
with its fiduciary duties to the Company's stockholders under applicable law;
provided, however, that neither the Company nor the Company Board nor any
committee thereof may, except as permitted by Section 5.5(b), withdraw or
modify, or propose publicly to withdraw or modify, its position with respect
to this Agreement or the Merger or approve or recommend, or propose publicly
to approve or recommend, a Takeover Proposal.
 
  5.6. ADDITIONAL AGREEMENTS. Subject to the terms and conditions herein
provided (including without limitation Section 5.3), 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 will
use their reasonable efforts to take, or cause to be taken, all such necessary
actions.
 
  5.7. PUBLICITY. So long as this Agreement is in effect, neither the Company
nor Parent nor Affiliates which either of them control may issue or cause the
publication of any press release or other public statement or announcement
with respect to this Agreement or the Stockholder Agreements or the
transactions contemplated hereby or thereby without the prior consultation of
the other party, except as may be required by law or by
 
                                     A-24
<PAGE>
 
obligations pursuant to any listing agreement with a national securities
exchange, in which case each party will use reasonable efforts to consult with
the other party prior to any such issuance.
 
  5.8. NOTIFICATION OF CERTAIN MATTERS. The Company will give prompt notice to
Parent, and Parent will give prompt notice to the Company, of the occurrence
or non-occurrence of any event known to the Company or Parent, respectively,
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 or would result in
noncompliance with or non-satisfaction of 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 5.8 will not limit or
otherwise affect the remedies available hereunder to the party receiving such
notice.
 
  5.9. DIRECTORS' AND OFFICERS' INSURANCE AND INDEMNIFICATION. The Surviving
Corporation will 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 required or permitted under the Certificate
of Incorporation or By-Laws of the Company, or any agreement with the Company
in each case as in effect immediately prior to the execution of this
Agreement, 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, state of affairs or occurrence 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 Surviving Corporation
will maintain in effect for not less than six 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, a comparably rated issuer 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 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 the Surviving Corporation will
provide the maximum coverage that will then be available at an annual premium
equal to 200% of such rate. The Surviving Corporation will pay in advance 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 5.9. The rights under this Section 5.9 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 5.9 are
contingent upon the occurrence of, and will survive consummation of, the
Merger and are expressly intended to benefit each Indemnified Party.
 
  5.10. RULE 145 AFFILIATES. Not later than the record date for the Company
Special Meeting, the Company will deliver to Parent a letter identifying, to
the Company's knowledge, all persons who are, at the time of the Company
Special Meeting, or may be deemed to be "affiliates" of the Company for
purposes of Rule 145 under the Securities Act ("Company Affiliates") and
thereafter will promptly update such letter if, to the Company's knowledge,
any other person becomes a Company Affiliate. The Company will 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 D to this Agreement.
 
  5.11. COOPERATION. Parent and the Company will 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, and (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
 
                                     A-25
<PAGE>
 
possible following the execution of this Agreement, the Company will cooperate
with Parent in the preparation and filing of the Proxy Statement/Prospectus
with the SEC, including 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 reasonable 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 will, subject to applicable law, confer on a regular and frequent
basis with one or more representatives of one another to report operational
matters of significance to the Merger and the general status of ongoing
operations insofar as relevant to the Merger, provided that the parties will
not confer on any matter to the extent inconsistent with law.
 
  5.12. PROXY STATEMENT/PROSPECTUS. As soon as practicable, Parent and the
Company will prepare and file with the SEC the Proxy Statement/Prospectus and
each will use reasonable efforts to have the Proxy Statement/Prospectus
cleared by the SEC as promptly as practicable. As soon as practicable
following such clearance Parent will prepare and file with the SEC the
Registration Statement, of which the Proxy Statement/Prospectus will form a
part, and will use reasonable efforts to have the Registration Statement
declared effective by the SEC as promptly as practicable thereafter. Parent
and the Company will cooperate with each other in the preparation of the Proxy
Statement/Prospectus, and each will provide to the other promptly copies of
all correspondence between it or any of its representatives and the SEC. Each
of the Company and Parent will furnish all information concerning it required
to be included in the Registration Statement and the Proxy
Statement/Prospectus, and as promptly as practicable after the effectiveness
of the Registration Statement, the Proxy Statement/Prospectus will be mailed
to the stockholders of the Company and Parent. No amendment or supplement to
the Registration Statement or the Proxy Statement/Prospectus will be made
without the approval of each of the Company and Parent, which approval will
not be unreasonably withheld or delayed. Each of the Company and Parent will
advise the other promptly after it receives notice thereof, of the time when
the Registration Statement has become effective or any amendment thereto or
any supplement or amendment to the Proxy Statement/Prospectus has been filed,
or the issuance of any stop order, or the suspension of the qualification of
the Parent Common Stock to be issued in the Merger for offering or sale in any
jurisdiction, or of any request by the SEC or the NYSE for amendment of the
Registration Statement or the Proxy Statement/Prospectus.
 
  5.13. COMPANY CONFIDENTIALITY AGREEMENT. The parties hereto agree that the
Company Confidentiality Agreement is hereby amended to provide that any
provision therein which in any manner limits, restricts or prohibits any of
the following will terminate as of the date hereof: the voting or acquisition
of beneficial ownership of shares of Common Stock by Parent or any of its
Affiliates pursuant to this Agreement or the Stockholder Agreements; the
transactions contemplated hereby and thereby; or the acquisition by Parent or
any of its Affiliates of beneficial ownership, whether pursuant to open-market
or privately negotiated purchases or other transactions otherwise than
pursuant to this Agreement or the Stockholder Agreements but in accordance
with applicable law, of Company Common Stock which, when added to the shares
of Common Stock subject to Section 3 of the Stockholder Agreements as of the
time of such acquisition, does not exceed 55% of the Company Common Stock
outstanding on a fully diluted basis. Except as otherwise provided in Section
5.5, the Company agrees not to take any action that would impede, bar,
restrict or otherwise interfere in any manner with Parent's rights under this
Agreement or the Stockholder Agreements, or voting or other rights in respect
of any shares of Company Common Stock acquired by Parent or any of its
Subsidiaries pursuant to this Agreement or any so-called "poison pill" or
other device which would dilute Parent's or any such Subsidiary's rights in
respect of any of the foregoing. The provisions of this Section 5.13 will
survive any termination of this Agreement; provided, however, that nothing in
this Agreement precludes the Company from implementing any measure (including,
without limitation, a so-called "poison pill" and amendments to its
Certificate of Incorporation and Bylaws) at any time that (i) is not
inconsistent with Parent's right to acquire shares of Company Common Stock
under the foregoing provisions of this Section 5.13 or with the exception to
Section 5.17(a) contained in the proviso thereto and (ii) is determined by the
Company Board to be appropriate to protect the interests of all stockholders.
 
                                     A-26
<PAGE>
 
  5.14. STOCK EXCHANGE LISTING. Parent will use reasonable efforts to list
prior to the Effective Time on the NYSE and the Pacific Stock Exchange,
subject to official notice of issuance, the shares of Parent Common Stock to
be issued in the Merger.
 
  5.15. REVISIONS OF SCHEDULES. At any time following the date hereof and
prior to October 23, 1996, to the extent any information in the Company
Disclosure Schedule shall be inaccurate, untrue or incomplete in any material
respect, the Company may, at its option, revise such information and provide
written notice of such revision to Parent, referencing this Section 5.15 in
such written notice, provided, however, that no such revision may be made in
respect of Section 3.3(b). In the event that Parent, after receiving such
written notice, fails to give notice of termination of this Agreement in
accordance with Section 7.1(c) within five business days of receipt thereof,
such revision will be deemed to be a part of the Company Disclosure Schedule
as if it had been included therein as of the date hereof.
 
  5.16. CERTAIN INTERIM OPERATIONS OF PARENT. Parent covenants and agrees
that, except as expressly provided in this Agreement, during the term of this
Agreement, without the prior written consent of the Company:
 
    (a) Parent will not, directly or indirectly, split, combine or reclassify
  the outstanding Parent Common Stock;
 
    (b) Neither Parent nor any of its Subsidiaries will declare, set aside or
  pay any dividend or other distribution payable in cash, stock or property
  with respect to its capital stock other than (i) dividends paid by Parent's
  Subsidiaries to Parent or its Subsidiaries and (ii) cash dividends on
  Parent Common Stock at Parent's current dividend rate or as such rate may
  be increased (provided that any such increase is not higher, on a
  percentage basis, after rounding up to avoid fractions, than Parent's most
  recent dividend rate increase prior to the date hereof); and Parent
  acknowledges that its current intention is to continue to pay cash
  dividends at a rate no less than the most recent dividend prior to the date
  hereof;
 
    (c) Parent may not adopt a plan of complete or partial liquidation or
  dissolution;
 
    (d) Neither Parent nor any of its Subsidiaries may take, or agree to
  commit to take, any action that would make any representation or warranty
  of Parent contained herein inaccurate in any material respect at, or as of
  any time prior to, the Effective Time; and
 
    (e) Neither Parent nor any of its Subsidiaries may enter into an
  agreement, contract, commitment or arrangement to do any of the foregoing,
  or to authorize, recommend, propose or announce an intention to do any of
  the foregoing.
 
  5.17. CERTAIN ADDITIONAL COVENANTS. (a) If this Agreement is terminated in
accordance with Section 7.1, for a period of four years from the date hereof,
except (i) within the terms of a specific written request from the Company, or
(ii) as contemplated by Section 5.13 prior to the termination of this
Agreement, Parent will not, and will use its best efforts to cause each of its
Affiliates controlled by it not to, 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, (a) any form of business
combination, acquisition or other similar transaction relating to the Company
or any subsidiary of the Company, (b) any form of restructuring,
recapitalization or similar transaction with respect to Company or any such
subsidiary, or (c) any demand, request or proposal to amend, waive or
terminate any provision of this Section 5.17, and except as aforesaid during
such period Parent will not, and will use its best efforts to cause each of
its Affiliates or any of its representatives as a principal not to, (A)
acquire, or offer, propose or agree to acquire, by purchase or otherwise, any
additional voting securities of Company, (B) make, or in any way participate
in, any solicitation of proxies with respect to any such voting securities
(including by the execution of action by written consent), become a
participant in any election contest with respect to Company, seek to influence
any person with respect to any such voting securities or demand a copy of the
list of the stockholders or other books and records of Company, (C)
participate in or encourage the formation of any partnership, syndicate or
other group which owns or seeks or offers to acquire beneficial ownership of

circumventing any provision of this Agreement, (D) 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, Board
of Directors or policies of Company, or (E) make any proposal or other
communication designed to compel Company to make a public announcement thereof
in respect of any matter referred to in this Section 5.17; provided, however,
that (x) if the Company initiates a process of soliciting bids for the
acquisition of the Company, Parent will be permitted to participate in such
process on the same basis, and subject to the same conditions and limitations,
as are established by the Company for all bidders and (y) if the Company
enters into an Acquisition Agreement with a party other than Parent and, as a
result, the Company Board has a fiduciary obligation under applicable Delaware
law to consider alternative Takeover Proposals, Parent will be permitted to
make a Takeover Proposal.
 
  (b) At the request of the Company, Parent will refinance, as of the Closing,
all of the Company's indebtedness and other obligations to the lenders under
the Bank Credit Agreement (as defined in the Company Disclosure Schedule),

are not amended, waived or otherwise modified following the date hereof
without Parent's consent.
 
  5.18. BOARD REPRESENTATION. If requested by the Company prior to the

effective as of the Effective Time as a member of the Parent Board in the
class of members thereof whose term expires at Parent's 1999 annual meeting of
stockholders.

    (b) by either the Company or Parent:
 
      (i) if the Merger shall not have been consummated by April 30, 1997;
    provided, however, that the right to terminate this Agreement pursuant

    failure to perform any of its obligations under this Agreement is the
    cause of or results in the failure of the Merger to be consummated by

      (ii) if, at a Company Special Meeting duly convened therefor and
    finally adjourned, the Company Stockholder Approval shall not have been
    obtained;
 
      (iii) if, at the Parent Special Meeting duly convened therefor and

    order or decree (a "Restraint") or taken any other action permanently
    enjoining, restraining or otherwise prohibiting the consummation of the
    Merger or any of the other transactions contemplated by this Agreement
    or the Stockholder Agreements and such Restraint or other action shall
    have become final and nonappealable;
 
    (c) by Parent, if the Company shall have breached or failed to perform in
  any material respect any of its representations, warranties, covenants or
  other agreements contained in this Agreement, which breach or failure to
  perform cannot be or has not been cured within 30 days after the giving of
  written notice to the Company of such breach (a "Company Material Breach")
  (provided that Parent is not then in Parent Material Breach (as defined in
  Section 7.1(f)) of any representation, warranty, covenant or other
  agreement contained in this Agreement);
 
    (d) by Parent if (i) the Company Board or any committee thereof shall

  recommendation of the Merger or this Agreement or approved or recommended
  any Takeover Proposal or (ii) the Company Board or any committee thereof
  shall have resolved to take any of the foregoing actions;
 
    (e) by Parent, if the Company or any of its officers, directors,
  employees, representatives or agents shall take any of the actions that
  would be proscribed by Section 5.5 but for the exceptions therein allowing
  certain actions to be taken based upon the fiduciary obligations of the
  Company Board; and
 
    (f) by the Company, if Parent shall have breached or failed to perform in
  any material respect any of its representations, warranties, covenants or
  other agreements contained in this Agreement, which breach or failure to
  perform cannot be or has not been cured within 30 days after the giving of
  written notice to Parent of such breach (a "Parent Material Breach")
  (provided that the Company is not then in Company Material Breach of any
  representation, warranty, covenant or other agreement contained in this
  Agreement).
 
  7.2. EFFECT OF TERMINATION. In the event of the termination of this
Agreement as provided in Section 7.1, written notice thereof will forthwith be
given to the other party or parties specifying the provision hereof pursuant
to which such termination is made, and this Agreement will forthwith become

Company except (a) for fraud or for intentional material breach of this
Agreement and (b) as set forth in Sections 5.13, 5.17(a) and 7.3.
 
  7.3. FEES AND EXPENSES; TERMINATION FEE. (a) Except as set forth in this
Section 7.3, all fees and expenses incurred in connection with the Merger,
this Agreement, the Stockholder Agreements and the transactions contemplated
hereby and thereby will be paid by the party incurring such fees or expenses,
whether
 
                                     A-30
<PAGE>
 
or not the Merger is consummated, except that each of the Company and Parent
will bear and pay one-half of the costs and expenses incurred in connection
with (i) the SEC filing fees and printing and mailing costs associated with
the Registration Statement and the Joint Proxy Statement and (ii) the filing
fees applicable to the premerger notification and report forms under the HSR
Act.
 
  (b) In the event that (i) a Takeover Proposal shall have been made known to
the Company or any of its subsidiaries or has been made directly to its
stockholders generally or any person shall have publicly announced an
intention (whether or not conditional) to make a Takeover Proposal and
thereafter Company Stockholder Approval is not obtained or (ii) this Agreement
is terminated by Parent pursuant to Section 7.1(d), then the Company will
promptly, but in no event later than two days after the date of such
termination, pay Parent a fee equal to $37.5 million (the "Termination Fee"),
payable by wire transfer of same day funds, plus upon Parent's request all
reasonable and documented out-of-pocket expenses incurred by Parent in
connection with this Agreement, the Stockholder Agreements and the
transactions contemplated hereby and thereby in an amount (as to such
expenses) not to exceed $5 million, which payments will be in addition to any
Termination Fee that may be payable. Notwithstanding any other provision
herein, no Termination Fee or any out-of-pocket expenses will be payable under
this Section 7.3(b) to Parent (i) if Parent shall have materially breached any
representation, warranty or covenant applicable to it hereunder and such
breach shall have given rise to a right of termination on the part of the
Company pursuant to Section 7.1(f) (excluding for this purpose the proviso
contained in the parenthetical at the end of Section 7.1(f)) or (ii) for any
reason other than the specific circumstances set forth in Section 7.3(b). The
Company acknowledges that the agreements contained in this Section 7.3(b) are
an integral part of the transactions contemplated by this Agreement, and that,
without these agreements, Parent would not enter into this Agreement;
accordingly, if the Company fails promptly to pay the amount due pursuant to
this Section 7.3(b), and, in order to obtain such payment, Parent commences a
suit which results in a judgment against the Company for the fee set forth in
Section 7.3(b), the Company will pay to Parent its reasonable costs and
expenses (including attorneys' fees and expenses) in connection with such
suit, together with interest on the amount of the fee at the prime rate of
Citibank N.A. in effect on the date such payment was required to be made.
 
  (c) In the event that this Agreement is terminated by the Company pursuant
to Section 7.1(b)(iii) or 7.1(f), then Parent will promptly, but in no event
later than two days after the date of such event, pay the Company a fee equal
to $37.5 million (the "Company Termination Fee"), plus upon the Company's
request all reasonable and documented out-of-pocket expenses incurred by the
Company in connection with this Agreement, the Stockholder Agreements and the
transactions contemplated hereby and thereby in an amount (as to such
expenses) not to exceed $5 million. Parent acknowledges that the agreements
contained in this Section 7.3(c) are an integral part of the transactions
contemplated by this Agreement, and that, without these agreements, the
Company would not enter into this Agreement; accordingly, if Parent fails
promptly to pay the amount due pursuant to this Section 7.3(c), and, in order
to obtain such payment, the Company commences a suit which results in a
judgment against Parent for the fee set forth in this Section 7.3(c), Parent
will pay to the Company its reasonable costs and expenses (including
attorneys' fees and expenses) in connection with such suit, together with
interest on the amount of the fee at the prime rate of Citibank N.A. in effect
on the date such payment was required to be made. Notwithstanding any other
provision herein, no Termination Fee or any out-of-pocket expenses will be
payable under this Section 7.3(c) to the Company (i) if the Company shall have
materially breached any representation, warranty or covenant applicable to it
hereunder and such breach shall have given rise to a right of termination on
the part of Parent pursuant to Section 7.1(c) (excluding for this purpose the
proviso contained in the parenthetical at the end of Section 7.1(c)) or (ii)
for any reason other than the specific circumstances set forth in this Section
7.3(c).

  FIFTH: The name and the mailing address of the incorporator is as follows:
Lawrence P. Lavan, 61 Broadway, New York, New York 10006.
 
  SIXTH: The corporation is to have perpetual existence.
 
  SEVENTH: Whenever a compromise or arrangement is proposed between the
corporation and its creditors or any class of them and/or between the
corporation and its stockholders or any class of them, any court of equitable
jurisdiction within the State of Delaware may, on the application in a summary
way of the corporation, or of any creditor or stockholder thereof or on the
application of any receiver or receivers appointed for the corporation under
the provisions of Section 291 of the General Corporation Law or on the
application of trustees in dissolution or of any receiver or receivers
appointed for the corporation under the provisions of Section 279 of the
General Corporation Law order a meeting of the creditors or class of creditors,
and/or of the stockholders or class of stockholders of the corporation, as the
case may be, to be summoned in such manner as the said court directs. If a
majority in number representing three-fourths in value of the creditors or
class of creditors, and/or of the stockholders or class of stockholders of the
corporation, as the case may be, agree to any compromise or arrangement and to
any reorganization of the corporation as consequence of such compromise or
arrangement, the said compromise or arrangement and the said reorganization
shall, if sanctioned by the court to which the said application has been made,
be binding on all the stockholders or class of stockholders, of the
corporation, as the case may be, and also on the corporation.
 
  EIGHTH: For the management of the business and for the conduct of the affairs
of the corporation, and in further definition, limitation and regulation of the
powers of the corporation and of its directors and stockholders, or any class
thereof, as the case may be, it is further provided:
 
    1. The management of the business and the conduct of the affairs of the
  corporation, including the election of the Chairman of the Board of
  Directors, if any, the President, the Treasurer, the Secretary, and other
  principal officers of the corporation, shall be vested in its Board of
  Directors. The number of Directors of the corporation shall be fixed by the
  By-Laws of the corporation and may be altered from time to time as provided
  therein, but in no event shall the number of directors of the corporation
  be less than three nor more than fifteen. A director shall be elected to
  hold office until the expiration of the term for which such person is
  elected, and until such person's successor shall be duly elected and
  qualified. The directors of the corporation shall be divided into three
  classes, as nearly equal in number as possible, designated Class I, Class
  II and Class III. The term of office of the initial Class I directors shall
  expire at the annual meeting of stockholders to be held in 1977; the term
  of office of the initial Class II directors shall expire at the annual
  meeting of stockholders to be held in 1978; and the term of office of the
  initial Class III directors shall expire at the annual meeting of
  stockholders to be held in 1979. At each annual meeting of stockholders
  commencing with the annual meeting to be held in 1977 for the purpose of
  electing a class of directors, persons shall be elected to hold office as
  such class of directors for a period of three years and until the third
  succeeding annual meeting of stockholders following the meeting at which
  they are elected. When the number of directors is changed, any newly
  created directorships or any decrease in directorships shall be so
  apportioned among the classes so as to make all classes as nearly equal in
  number as possible. Any vacancies created in the Board of Directors through
  increase in the number of directors or otherwise, may be filled in
  accordance with the By-Laws of the corporation and the applicable laws of
  the State of Delaware. Election of directors need not be by written ballot.
 
    2. The original By-Laws of the corporation shall be adopted by the
  incorporator. Thereafter, the power to make, alter, or repeal the By-Laws,
  and to adopt any new By-Law, except a By-Law classifying directors for
  election for staggered terms, shall be vested in the Board of Directors.
 
                                      A-36
<PAGE>
 
    3. Whenever the corporation shall be authorized to issue more than one
  class of stock, one or more of which is denied voting power, no outstanding
  share of any class of stock which is denied voting power under this
  Certificate of Incorporation shall entitle the holder thereof to notice of,
  and the right to vote, at any meeting of stockholders except as the
  provisions of paragraph (b)(2) of Section 242 of the General Corporation
  Law and of Section 251, 252, and 253 of the General Corporation Law shall
  otherwise require; provided, that no share of any such class which is
  otherwise denied voting power shall entitle the holder thereof to vote upon
  the increase or decrease in the number of authorized shares of said class.
 
    4. In lieu of taking any permissive or requisite action by vote at a
  meeting of stockholders, any such vote and any such meeting may be
  dispensed with if either all of the stockholders entitled to vote upon the
  action at any such meeting shall consent in writing to any such corporate
  action being taken or if less then all of the stockholders entitled to vote
  upon the action at any such meeting shall consent in writing to any such
  corporate action being taken; provided, that any such action taken upon
  less than the unanimous written consent of all stockholders entitled to
  vote upon any such action shall be by the written consent of the
  stockholders holding at least the minimum percentage of the votes required
  to be cast to authorize any such action under the provisions of the General
  Corporation Law or under the provisions of this Certificate of
  Incorporation or the By-Laws as permitted by the provisions of the General
  Corporation Law; and, provided, that prompt notice be given to all
  stockholders entitled to vote on any such action or the taking of such
  action without a meeting and by less than unanimous written consent.
 
  NINTH: No contract or transaction between the corporation and one or more of
its directors or officers, or between the corporation and any other
corporation, partnership, association, or other organization in which one or
more of its directors or officers are directors or officers, or have a
financial interest, shall be void or voidable solely for this reason, or solely
because the director or officer is present at or participates in the meeting of
the Board of Directors or a committee thereof which authorizes the contract or
transaction, or solely because his or their votes are counted for such purpose,
if:
 
    (a) The material facts as to his interest and as to the contract or
  transaction are disclosed or are known to the Board of Directors or the
  committee, and the Board or committee in good faith authorizes the contract
  or transaction by a vote sufficient for such purpose without counting the
  vote of the interested director or directors; or
 
    (b) The material facts as to his interest and as to the contract or
  transaction are disclosed or are known to the stockholders entitled to vote
  thereon, and the contract or transaction is specifically approved in good
  faith by vote of the stockholders; or
 
    (c) The contract or transaction is fair as to the corporation as of the
  time it is authorized, approved or ratified, by the Board of Directors, a
  committee thereof, or the stockholders.
 
  Interested directors may be counted in determining the presence of a quorum
at a meeting of the Board of Directors or of a committee which authorizes the
contract or transaction.
 
  TENTH:
 
  A. Modification of Certain Liability of Directors.
 
  A director of the corporation shall not be personally liable to the
corporation or its stockholders for monetary damages for breach of fiduciary
duty as a director, except for liability (i) for any breach of the director's
duty of loyalty to the corporation or its stockholders, (ii) for acts or
omissions not in good faith or which involve intentional misconduct or a
knowing violation of law, (iii) under Section 174 of the General Corporation
Law, or (iv) for any transaction from which the director derived an improper
personal benefit. If the General Corporation Law is amended to authorize
corporate action further eliminating or limiting the personal liability of
directors, then the liability of a director of the corporation shall be
eliminated or limited to the fullest extent permitted by the General
Corporation Law, as so amended. Any repeal or modification of this Section A or
B by the stockholders of the corporation shall not adversely affect any right
or protection of a director of the corporation existing at the time of such
repeal or modification.
 
                                      A-37

  B. Indemnification and Insurance.
 
  (1) Right to Indemnification. Each person who was or is made a party or is
threatened to be made a party to or is involved in any action, suit or
proceeding, whether civil, criminal, administrative or investigative
(hereinafter a "proceeding"), by reason of the fact that he or she or a person
of whom he or she is the legal representative is or was a director or officer
of the corporation or is or was serving at the request of the corporation as a
director or officer of another corporation or of a partnership, joint venture,
trust or other enterprise, including service with respect to employee benefit
plans, whether the basis of such proceeding is alleged action in an official
capacity as a director or officer or in any other capacity while serving as a
director or officer shall be indemnified and held harmless by the corporation
to the fullest extent authorized by the General Corporation Law as the same
exists or may hereafter be amended (but, in the case of any such amendment,
only to the extent that such amendment permits the corporation to provide
broader indemnification rights than said law permitted the corporation to
provide prior to such amendment), against all expense, liability and loss
(including attorneys' fees, judgments, fines, ERISA excise taxes or penalties
and amounts paid or to be paid in settlement) reasonably incurred or suffered
by such person in connection therewith and such indemnification shall continue
as to a person who has ceased to be a director, officer, employee or agent and
shall inure to the benefit of his or her heirs, executors and administrators;
provided, however, that except as provided in paragraph (2) of this Section B
with respect to proceedings seeking to enforce rights to indemnification, the
corporation shall indemnify any such person seeking indemnification in
connection with a proceeding (or part thereof) initiated by such person only if
such proceeding (or part thereof) was authorized by the Board of Directors of
the corporation. The right to indemnification conferred in this Section B shall
be a contract right and shall include the right to be paid by the corporation
the expenses incurred in defending any such proceeding in advance of its final
disposition; provided, however, that if the General Corporation Law requires,
the payment of such expenses incurred by a director or officer in his or her
capacity as a director or officer (and not in any other capacity in which
service was or is rendered by such person while a director or officer,
including, without limitation, service to any employee benefit plan) in advance
of the final disposition of a proceeding, shall be made only upon delivery to
the corporation of an undertaking by or on behalf of such director or officer,
to repay all amounts so advanced if it shall ultimately be determined that such
director or officer is not entitled to be indemnified under this Section B or
otherwise.
 
  (2) Right of Claimant to Bring Suit. If a claim under paragraph (1) of this
Section B is not paid in full by the corporation within the thirty days after a
written claim has been received by the corporation, the claimant may at any
time thereafter bring suit against the corporation to recover the unpaid amount
of the claim and, if successful in whole or in part, the claimant shall be
entitled to be paid also the expense of prosecuting such claim. It shall be a
defense to any such action (other than an action brought to enforce a claim for
expenses incurred in defending any proceeding in advance of its final
disposition where the required undertaking, if any is required, has been
tendered to the corporation) that the claimant has not met the standards of
conduct which make it permissible under the General Corporation Law for the
corporation to indemnify the claimant for the amount claimed, but the burden of
proving such defense shall be on the corporation. Neither the failure of the
corporation (including its Board of Directors, independent legal counsel or
stockholders) to have made a determination prior to the commencement of such
action that indemnification of the claimant is proper in the circumstances
because he or she has met the applicable standard of conduct set forth in the
General Corporation Law, nor an actual determination by the corporation
(including its Board of Directors, independent legal counsel or stockholders)
that the claimant has not met such applicable standard of conduct, shall be a
defense to the action or create a presumption that the claimant has not met the
applicable standard of conduct.
 
  (3) Non Exclusivity of Rights. The right to indemnification and the payment
of expenses incurred in defending a proceeding in advance of its final
disposition conferred in this Section B shall not be exclusive of any other
right which any person may have or hereafter acquire under any statute,
provision of this Certificate of Incorporation, By-Law, agreement, vote of
stockholders or disinterested directors or otherwise.
 
  (4) Insurance. The corporation may maintain insurance, at its expense, to
protect itself and any director, officer, employee or agent of the corporation
or another corporation, partnership, joint venture, trust or other
 
                                      A-38
<PAGE>
 
enterprise against any expense, liability or loss, whether or not the
corporation would have the power to indemnify such person against such expense,
liability or loss under the General Corporation Law.
 
  ELEVENTH: From time to time any of the provisions of this Certificate of
Incorporation may be amended, altered or repealed, and other provisions
authorized by the laws of the State of Delaware at the time in force may be
added or inserted in the manner and at the time prescribed by said law, and all
rights at any time conferred upon the stockholders of the corporation by this
Certificate of Incorporation are granted subject to the provisions of this
Article ELEVENTH.

Business Combination with any Related Person. Such affirmative vote shall be
required notwithstanding the fact that no vote, or a lesser percentage, may be

    series of stock of the corporation in a Business Combination with a
    Related Person is not less than the highest per share price (including
    brokerage commissions and/or soliciting dealers' fees) paid by such

    respectively;
 
      (ii) The consideration to be received by holders of a particular
    class of securities shall be in cash or in the same form as the Related

    of the corporation for the purpose of soliciting stockholder approval
    of the Business Combination and shall contain at the front thereof, in
    a prominent place, any recommendations as to the advisability (or
    inadvisability) of the Business Combination which the Continuing
    Directors, or any of them, may choose to state and, if deemed advisable
    by a majority of the Continuing Directors, an opinion of a reputable
    investment banking firm as to the fairness (or not) of the terms of
    such Business Combination, from the point of view of the remaining
    public stockholders of the corporation (such investment banking firm to
    be selected by a majority of the Continuing Directors and to be paid a
    reasonable fee for their services by the corporation upon receipt of
    such opinion).
 
  The provisions of this Article TWELFTH shall also apply to a Business
Combination with any Person which at any time has been a Related Person,
notwithstanding the fact that such Person is no longer a Related Person, if, at
the time the definitive agreement or other arrangements relating to a Business
Combination with such Person was entered into, it was a Related Person or if,
as of the record date for the determination of stockholders entitled to notice
of and to vote on the Business Combination, such Person is an Affiliate of the

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
Exchange Ratio (as defined below) pursuant to the terms of the Agreement and
Plan of Merger dated as of October 13, 1996 (the "Agreement"), between the
Company and Thrifty PayLess Holdings, Inc. ("Thrifty PayLess") pursuant to
which Thrifty PayLess will be merged with and into the Company (the "Merger").
 
  Pursuant to the Agreement, each share of Class A Common Stock, par value
$.01 per share ("Class A Common Stock"), of Thrifty PayLess and each share of
Class B Common Stock, par value $.01 per share ("Class B Common Stock") of
Thrifty PayLess will be converted into the right to receive, subject to
certain exceptions, 0.65 shares (the "Exchange Ratio") of Common Stock, par
value $1.00 per share of the Company ("Rite Aid Common Stock").
 
  In arriving at our opinion, we have reviewed the Agreement as well as
financial and other information that was publicly available or furnished to us
by the Company and Thrifty PayLess including information provided during
discussions with their respective managements. Included in the information
provided during discussions with the respective managements were certain
internal financial analyses and forecasts for the Company and Thirty PayLess
prepared by their respective managements. In addition, we have compared
certain financial and securities data of the Company and Thrifty PayLess with
various other companies whose securities are traded in public markets,
reviewed the historical stock prices and trading volumes of the Class B Common
Stock and Rite Aid Common Stock, reviewed prices and premiums paid in certain
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 Thrifty PayLess 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 and interest expense
savings achievable as a result of the Merger. With respect to the financial
analyses and forecasts 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 Thrifty PayLess
as to the future operating and financial performance of the Company and
Thrifty PayLess. We have not assumed any responsibility for making any
independent evaluation of the assets or liabilities of Thrifty PayLess or for
making any independent verification of any of the information reviewed by us.
We have relied as to all legal matters on advice of counsel to the Company.
 
  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

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 Rite Aid Common Stock will trade at any time. Our
opinion does not constitute a recommendation to any stockholder of the Company
or Thrifty PayLess 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
Thrifty PayLess 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 and acted as dealer
manager for the Company with respect to its attempted acquisition of Revco
D.S., Inc. DLJ has received customary compensation for the above-mentioned
services. Over the past two years, DLJ has also (i) co-managed the $408.8
million initial public offering of Thrifty PayLess Class B Common Stock and
(ii) acted as financial advisor to Thrifty PayLess, Inc. and Thrifty PayLess
and as dealer manager in conjunction with the tender offers for $249.6 million
of 11 3/4% Senior Notes due 2003 and $12.7 million of 11 5/8% Senior Notes due
2006, respectively. DLJ has also received customary compensation for the
abovementioned services. In addition, in connection with Green Equity Partners
L.P's acquisition of Thrifty Corporation from Pacific Enterprises, DLJ and its
affiliates currently own less than 6% of the Class A Common Stock and less than
1% of the Class B Common Stock.
 
  Based upon the foregoing and, other factors as we deem relevant, we are of
the opinion that the Exchange Ratio is fair to the stockholders of the Company
from a financial point of view.
 
                                          Very truly yours,

Gentlemen and Madame:
   
  You have requested our opinion as to the fairness to the holders of the
outstanding shares of Class A Common Stock, par value $0.01 per share, and
Class B Common Stock, par value $0.01 per share (collectively, the "Common
Stock"), of Thrifty PayLess Holdings, Inc. (the "Company") of the exchange
ratio of .65 shares of Common Stock, par value $1.00 per share (the "Rite Aid
Common Stock"), of Rite Aid Corporation ("Rite Aid") to be received for each
share of Common Stock (the "Exchange Ratio") pursuant to the Agreement and
Plan of Merger dated as of October 13, 1996 by and between Rite Aid and the
Company (the "Agreement"). The Agreement provides for the Company to be merged
with and into Rite Aid (the "Merger").

  Goldman, Sachs & Co., 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 biddings, secondary distributions of listed and unlisted
securities, private placements and valuations for estate, corporate and other
purposes. We are familiar with the Company having provided certain investment
banking services to the Company from time to time, including having acted as
the managing underwriter of the initial public offering of the Class B Common
Stock of the Company in April 1996 and having acted as its financial advisor
in connection with, and having participated in certain of the negotiations
leading to, the Agreement. We have also provided certain investment banking
services to Rite Aid from time to time, including participation in its
commercial paper program, and may provide services to Rite Aid in the future.
In the course of the trading activities of Goldman, Sachs & Co., the Firm
accumulated a short position of 102,852 shares of Rite Aid Common Stock, a
long position of $7,159,000 of 0% convertible bonds of Rite Aid, a long
position of $15,000,000 of commercial paper of Rite Aid, and a long position
of $20,000,000 of the bank debt of the Company.
 
  In connection with this opinion, we have reviewed, among other things, the
Agreement, the Company's Registration Statement on Form S-1 dated April 15,
1996; audited financial statements of the Company for the three fiscal years
ended October 1, 1995; Annual Reports to Stockholders and Annual Reports on
Form 10-K of
                                      C-1

Rite Aid for the five fiscal years ended March 2, 1996; certain interim reports
to stockholders and Quarterly Reports on Form 10-Q of the Company and Rite Aid;
certain other communications from the Company and Rite Aid to their respective
stockholders; and certain internal financial analyses and forecasts for the
Company and Rite Aid prepared by their respective managements. We also have
held discussions with members of the senior management of the Company and Rite
Aid regarding the past and current business operations, financial condition and
future prospects of their respective companies and with respect to the
strategic and operational benefits projected to be derived from the Merger,
including certain cost savings and operational synergies expected to the
realized. In addition, we have reviewed the reported price and trading activity
for the Common Stock and Rite Aid Common Stock, compared certain financial and
stock market information for the Company and Rite Aid with similar information
for certain other companies the securities of which are publicly traded,
reviewed the financial terms of certain recent business combinations in the
drug store industry specifically and in other industries generally and
performed such other studies and analyses as we considered appropriate.
 
  We have relied without independent verification upon the accuracy and
completeness of all of the financial and other information reviewed by us for
purposes of this opinion. In addition, we have not made an independent
evaluation or appraisal of the assets and liabilities of the Company or Rite
Aid or any of their subsidiaries and we have not been furnished with any such
evaluation or appraisal. Our advisory services and the opinion expressed herein
are provided for the information and assistance of the Board of Directors of
the Company in connection with its consideration of the transaction
contemplated by the Agreement.
 
  Based upon the foregoing and such other matters as we consider relevant, it
is our opinion that as of the date hereof the Exchange Ratio pursuant to the
Agreement is fair to the holders of Common Stock.

(S) 262. APPRAISAL RIGHTS
 
  (a) Any stockholder of a corporation of this State who holds shares of stock
on the date of the making of a demand pursuant to subsection (d) of this
section with respect to such shares, who continuously holds such shares
through the effective date of the merger or consolidation, who has otherwise
complied with subsection (d) of this section and who has neither voted in
favor of the merger or consolidation nor consented thereto in writing pursuant
to (S) 228 of this title shall be entitled to an appraisal by the Court of
Chancery of the fair value of his shares of stock under the circumstances
described in subsections (b) and (c) of this section. As used in this section,
the word "stockholder" means a holder of record of stock in a stock
corporation and also a member of record of a nonstock corporation; the words
"stock" and "share" mean and include what is ordinarily meant by those words
and also membership or membership interest of a member of a nonstock
corporation; and the words "depository receipt" mean a receipt or other
instrument issued by a depository representing an interest in one or more
shares, or fractions thereof, solely of stock of a corporation, which stock is
deposited with the depository.
 
  (b) Appraisal rights shall be available for the shares of any class or
series of stock of a constituent corporation in a merger or consolidation to
be effected pursuant to (S) 251 (other than a merger effected pursuant to
subsection (g) of Section 251), (S) 252, (S) 254, (S) 257, (S) 258, (S) 263 or
(S) 264 of this title:
 
    (1) Provided, however, that no appraisal rights under this section shall
  be available for the shares of any class or series of stock, which stock,
  or depository receipts in respect thereof, at the record date fixed to
  determine the stockholders entitled to receive notice of and to vote at the
  meeting of stockholders to act upon the agreement of merger or
  consolidation, were either (i) listed on a national securities exchange or
  designated as a national market system security on an interdealer quotation
  system by the National Association of Securities Dealers, Inc. or (ii) held
  of record by more than 2,000 holders; and further provided that no
  appraisal rights shall be available for any shares of stock of the
  constituent corporation surviving a merger if the merger did not require
  for its approval the vote of the stockholders of the surviving corporation
  as provided in subsection (f) of (S) 251 of this title.
 
    (2) Notwithstanding paragraph (1) of this subsection, appraisal rights
  under this section shall be available for the shares of any class or series
  of stock of a constituent corporation if the holders thereof are required
  by the terms of an agreement of merger or consolidation pursuant to (S)(S)
  251, 252, 254, 257, 258, 263 and 264 of this title to accept for such stock
  anything except:
 
      a. Shares of stock of the corporation surviving or resulting from
    such merger or consolidation, or depository receipts in respect
    thereof;
 
      b. Shares of stock of any other corporation, or depository receipts
    in respect thereof, which shares of stock or depository receipts at the
    effective date of the merger or consolidation will be either listed on
    a national securities exchange or designated as a national market
    system security on an interdealer quotation system by the National
    Association of Securities Dealers, Inc. or held of record by more than
    2,000 holders;
 
      c. Cash in lieu of fractional shares or fractional depository
    receipts described in the foregoing subparagraphs a. and b. of this
    paragraph; or
 
      d. Any combination of the shares of stock, depository receipts and
    cash in lieu of fractional shares or fractional depository receipts
    described in the foregoing subparagraphs a., b. and c. of this
    paragraph.
 
    (3) In the event all of the stock of a subsidiary Delaware corporation
  party to a merger effected under (S) 253 of this title is not owned by the
  parent corporation immediately prior to the merger, appraisal rights shall
  be available for the shares of the subsidiary Delaware corporation.
 
  (c) Any corporation may provide in its certificate of incorporation that
appraisal rights under this section shall be available for the shares of any
class or series of its stock as a result of an amendment to its certificate of
 
                                      D-1
<PAGE>
 
incorporation, any merger or consolidation in which the corporation is a
constituent corporation or the sale of all or substantially all of the assets
of the corporation. If the certificate of incorporation contains such a
provision, the procedures of this section, including those set forth in
subsections (d) and (e) of this section, shall apply as nearly as is
practicable.
 
  (d) Appraisal rights shall be perfected as follows:
 
    (1) If a proposed merger or consolidation for which appraisal rights are
  provided under this section is to be submitted for approval at a meeting of
  stockholders, the corporation, not less than 20 days prior to the meeting,
  shall notify each of its stockholders who was such on the record date for
  such meeting with respect to shares for which appraisal rights are
  available pursuant to subsection (b) or (c) hereof that appraisal rights
  are available for any or all of the shares of the constituent corporations,
  and shall include in such notice a copy of this section. Each stockholder
  electing to demand the appraisal of his shares shall deliver to the
  corporation, before the taking of the vote on the merger or consolidation,
  a written demand for appraisal of his shares. Such demand will be
  sufficient if it reasonably informs the corporation of the identity of the
  stockholder and that the stockholder intends thereby to demand the
  appraisal of his shares. A proxy or vote against the merger or
  consolidation shall not constitute such a demand. A stockholder electing to
  take such action must do so by a separate written demand as herein
  provided. Within 10 days after the effective date of such merger or
  consolidation, the surviving or resulting corporation shall notify each
  stockholder of each constituent corporation who has complied with this
  subsection and has not voted in favor of or consented to the merger or
  consolidation of the date that the merger or consolidation has become
  effective; or
     
    (2) If the merger or consolidation was approved pursuant to (S)228 or
  (S)253 of this title, each constituent corporation, either before the
  effective date of the merger or consolidation or within ten days
  thereafter, shall notify each of the holders of any class or series of
  stock of such constituent corporation who are entitled to appraisal rights
  of the approval of the merger or consolidation and that appraisal rights
  are available for any or all shares of such class or series of stock of
  such constituent corporation, and shall include in such notice a copy of
  this section; provided that, if the notice is given on or after the
  effective date of the merger or consolidation, such notice shall be given
  by the surviving or resulting corporation to all such holders of any class
  or series of stock of a constituent corporation that are entitled to
  appraisal rights. Such notice may, and, if given on or after the effective
  date of the merger or consolidation, shall, also notify such stockholders
  of the effective date of the merger or consolidation. Any stockholder
  entitled to appraisal rights may, within twenty days after the date of
  mailing of such notice, demand in writing from the surviving or resulting
  corporation the appraisal of such holder's shares. Such demand will be
  sufficient if it reasonably informs the corporation of the identity of the
  stockholder and that the stockholder intends thereby to demand the
  appraisal of such holder's shares. If such notice did not notify
  stockholders of the effective date of the merger or consolidation, either
  (i) each such constituent corporation shall send a second notice before the
  effective date of the merger or consolidation notifying each of the holders
  of any class or series of stock of such constituent corporation that are
  entitled to appraisal rights of the effective date of the merger or
  consolidation or (ii) the surviving or resulting corporation shall send
  such a second notice to all such holders on or within 10 days after such
  effective date; provided, however, that if such second notice is sent more
  than 20 days following the sending of the first notice, such second notice
  need only be sent to each stockholder who is entitled to appraisal rights
  and who has demanded appraisal of such holder's shares in accordance with
  this subsection. An affidavit of the secretary or assistant secretary or of
  the transfer agent of the corporation that is required to give either
  notice that such notice has been given shall, in the absence of fraud, be
  prima facie evidence of the facts stated therein. For purposes of
  determining the stockholders entitled to receive either notice, each
  constituent corporation may fix, in advance, a record date that shall be
  not more than 10 days prior to the date the notice is given; provided that,
  if the notice is given on or after the effective date of the merger or
  consolidation, the record date shall be such effective date. If no record
  date is fixed and the notice is given prior to the effective date, the
  record date shall be the close of business on the day next preceding the
  day on which the notice is given.     
 
  (e) Within 120 days after the effective date of the merger or consolidation,
the surviving or resulting corporation or any stockholder who has complied
with subsections (a) and (d) hereof and who is otherwise
 
                                      D-2
<PAGE>
 
entitled to appraisal rights, may file a petition in the Court of Chancery
demanding a determination of the value of the stock of all such stockholders.
Notwithstanding the foregoing, at any time within 60 days after the effective
date of the merger or consolidation, any stockholder shall have the right to
withdraw his demand for appraisal and to accept the terms offered upon the
merger or consolidation. Within 120 days after the effective date of the
merger or consolidation, any stockholder who has complied with the
requirements of subsections (a) and (d) hereof, upon written request, shall be
entitled to receive from the corporation surviving the merger or resulting
from the consolidation a statement setting forth the aggregate number of
shares not voted in favor of the merger or consolidation and with respect to
which demands for appraisal have been received and the aggregate number of
holders of such shares. Such written statement shall be mailed to the
stockholder within 10 days after his written request for such a statement is
received by the surviving or resulting corporation or within 10 days after
expiration of the period for delivery of demands for appraisal under
subsection (d) hereof, whichever is later.
 
  (f) Upon the filing of any such petition by a stockholder, service of a copy
thereof shall be made upon the surviving or resulting corporation, which shall
within 20 days after such service file in the office of the Register in
Chancery in which the petition was filed a duly verified list containing the
names and addresses of all stockholders who have demanded payment for their
shares and with whom agreements as to the value of their shares have not been
reached by the surviving or resulting corporation. If the petition shall be
filed by the surviving or resulting corporation, the petition shall be
accompanied by such a duly verified list. The Register in Chancery, if so
ordered by the Court, shall give notice of the time and place fixed for the
hearing of such petition by registered or certified mail to the surviving or
resulting corporation and to the stockholders shown on the list at the
addresses therein stated. Such notice shall also be given by 1 or more
publications at least 1 week before the day of the hearing, in a newspaper of
general circulation published in the City of Wilmington, Delaware or such
publication as the Court deems advisable. The forms of the notices by mail and
by publication shall be approved by the Court, and the costs thereof shall be
borne by the surviving or resulting corporation.
 
  (g) At the hearing on such petition, the Court shall determine the
stockholders who have complied with this section and who have become entitled
to appraisal rights. The Court may require the stockholders who have demanded
an appraisal for their shares and who hold stock represented by certificates
to submit their certificates of stock to the Register in Chancery for notation
thereon of the pendency of the appraisal proceedings; and if any stockholder
fails to comply with such direction, the Court may dismiss the proceedings as
to such stockholder.
 
  (h) After determining the stockholders entitled to an appraisal, the Court
shall appraise the shares, determining their fair value exclusive of any
element of value arising from the accomplishment or expectation of the merger
or consolidation, together with a fair rate of interest, if any, to be paid
upon the amount determined to be the fair value. In determining such fair
value, the Court shall take into account all relevant factors. In determining
the fair rate of interest, the Court may consider all relevant factors,
including the rate of interest which the surviving or resulting corporation
would have had to pay to borrow money during the pendency of the proceeding.
Upon application by the surviving or resulting corporation or by any
stockholder entitled to participate in the appraisal proceeding, the Court
may, in its discretion, permit discovery or other pretrial proceedings and may
proceed to trial upon the appraisal prior to the final determination of the
stockholder entitled to an appraisal. Any stockholder whose name appears on
the list filed by the surviving or resulting corporation pursuant to
subsection (f) of this section and who has submitted his certificates of stock
to the Register in Chancery, if such is required, may participate fully in all
proceedings until it is finally determined that he is not entitled to
appraisal rights under this section.
 
  (i) The Court shall direct the payment of the fair value of the shares,
together with interest, if any, by the surviving or resulting corporation to
the stockholders entitled thereto. Interest may be simple or compound, as the
Court may direct. Payment shall be so made to each such stockholder, in the
case of holders of uncertificated stock forthwith, and the case of holders of
shares represented by certificates upon the surrender to the corporation of
the certificates representing such stock. The Court's decree may be enforced
as other decrees in the Court of Chancery may be enforced, whether such
surviving or resulting corporation be a corporation of this State or of any
state.
 
                                      D-3
<PAGE>
 
  (j) The costs of the proceeding may be determined by the Court and taxed
upon the parties as the Court deems equitable in the circumstances. Upon
application of a stockholder, the Court may order all or a portion of the
expenses incurred by any stockholder in connection with the appraisal
proceeding, including, without limitation, reasonable attorney's fees and the
fees and expenses of experts, to be charged pro rata against the value of all
the shares entitled to an appraisal.
 
  (k) From and after the effective date of the merger or consolidation, no
stockholder who has demanded his appraisal rights as provided in subsection
(d) of this section shall be entitled to vote such stock for any purpose or to
receive payment of dividends or other distributions on the stock (except
dividends or other distributions payable to stockholders of record at a date
which is prior to the effective date of the merger or consolidation);
provided, however, that if no petition for an appraisal shall be filed within
the time provided in subsection (e) of this section, or if such stockholder
shall deliver to the surviving or resulting corporation a written withdrawal
of his demand for an appraisal and an acceptance of the merger or
consolidation, either within 60 days after the effective date of the merger or
consolidation as provided in subsection (e) of this section or thereafter with
the written approval of the corporation, then the right of such stockholder to
an appraisal shall cease. Notwithstanding the foregoing, no appraisal
proceeding in the Court of Chancery shall be dismissed as to any stockholder
without the approval of the Court, and such approval may be conditioned upon
such terms as the Court deems just.
 
  (l) The shares of the surviving or resulting corporation to which the shares
of such objecting stockholders would have been converted had they assented to
the merger or consolidation shall have the status of authorized and unissued
shares of the surviving or resulting corporation.

                                    PART II
 
                    INFORMATION NOT REQUIRED IN PROSPECTUS
 
ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
  Rite Aid is a Delaware corporation. The Delaware General Corporation Law
(the "DGCL") generally provides that a director, employee, officer or agent of
a Delaware corporation who was or is a party or is threatened to be made a
party to any threatened, pending or completed action, suit or proceeding,
whether civil, criminal, administrative or investigative, may be indemnified
against liability, expenses (including attorneys' fees), judgments, fines and
amounts paid in settlement actually and reasonably incurred by such person in
connection with such proceeding (other than in a proceeding by or in the right
of the corporation), provided such person acted in good faith and in a manner
such person reasonably believed to be in, or at least not opposed to, the best
interests of the corporation, and, with respect to any criminal proceeding,
had no reasonable cause to believe the conduct was unlawful. For actions or
suits brought by or in the right of the corporation, the DGCL provides that a
director, employee, officer or agent of a Delaware corporation may be
indemnified against expenses (including attorneys' fees) as incurred by such
person in connection with such proceeding if such person acted in good faith
and in a manner such person reasonably believed to be in, or at least not
opposed to, the best interests of the corporation, except that if such person
is adjudged to be liable to the corporation, such person can be indemnified if
and only to the extent that a court determines that despite the adjudication
of liability, in view of all the circumstances of the case, such person is
fairly and reasonably entitled to indemnity for such expenses as the court
shall deem proper.
 
  In addition to the provisions of the DGCL described in the immediately
preceding paragraph, the Rite Aid By-laws also provide that in the judgment of
a majority of a disinterested quorum of the Board of Directors of Rite Aid
(the "Rite Aid Board"), any director, officer or employee will be entitled to
indemnification in such amounts as the Rite Aid Board deems necessary to cover
the reasonable costs and expenses of such person to be indemnified.
 
  The DGCL provides that a corporation may include, in its articles or
certificate of incorporation, a provision which limits or eliminates the
personal liability of a director to the corporation or its stockholders for
monetary damages for such person's conduct as a director, provided that such
provision may not so limit a director's liability (i) for a breach of his or
her duty of loyalty to the corporation or its stockholders; (ii) for acts or
omissions not in good faith or involving intentional misconduct or a knowing
violation of law; (iii) for unlawful payments of dividends, certain stock
repurchases or redemptions; or (iv) for any transaction from which the
director derived an improper personal benefit. The Rite Aid Certificate of
Incorporation so limits the personal liability of directors to the fullest
extent permitted under the DGCL. The DGCL further provides that where a
director, officer, employee or agent of a corporation has been successful on
the merits or otherwise in defense of any action, suit or proceeding for which
indemnification is permissible, or in defense of any claim, issue or matter
related thereto, he shall be indemnified against expenses (including
attorneys' fees) actually and reasonably incurred by him in connection
therewith.
 
  Pursuant to the Agreement and Plan of Merger, dated as of October 13, 1996,
by and between Rite Aid and Thrifty PayLess (the "Merger Agreement"), Rite Aid
agreed that at all times after the effective time of the Merger (the
"Effective Time"), it will indemnify such 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 Thrifty PayLess or of any of Thrifty PayLess'
subsidiaries, successors and assigns (individually an "Indemnified Party" and
collectively the "Indemnified Parties"), to the fullest extent required or
permitted under the Certificate of Incorporation or By-Laws of Thrifty
PayLess, or any agreement with Thrifty PayLess, in each case as in effect
immediately prior to the execution of the Merger Agreement 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, state of affairs or occurrence existing or occurring at or
prior to the Effective Time whether commenced, asserted or claimed before or
after the Effective Time, including liability arising
 
                                     II-1
<PAGE>
 
under the Securities Act, the Securities Exchange Act of 1934, as amended (the
"Exchange Act"), or state law. The Merger Agreement provides that Rite Aid
will maintain in effect for not less than six years after the Effective Time
the current policies of directors' and officers' liability insurance
maintained by Thrifty PayLess and its subsidiaries on the date of the Merger
Agreement (provided that Rite Aid may substitute therefor policies having at
least the same coverage, a comparatively rated issuer 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 Thrifty PayLess and its
subsidiaries for such insurance on the date of the Merger Agreement, then Rite
Aid 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 in advance 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, or other similar organizational
documents of Thrifty PayLess 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.

ITEM 22. UNDERTAKINGS.
 
  (a) The undersigned Registrant hereby undertakes as follows:
 
    1. To file, during any period in which offers or sales are being made, a
  post-effective amendment to this Registration Statement:
 
      (i) To include any prospectus required by Section 10(a)(3) of the
    Securities Act;
 
      (ii) To reflect in the prospectus any facts or events arising after
    the effective date of the Registration Statement (or the most recent
    post-effective amendment thereof) which, individually or in the
    aggregate, represent a fundamental change in the information set forth
    in the Registration Statement. Notwithstanding the foregoing, any
    increase or decrease in the volume of the securities offered (if the
    total dollar value of securities offered would not exceed that which
    was registered) and any deviation from the low or high and of the
    estimated maximum offering range may be reflected in the form of
    prospectus filed with the Commission pursuant to Rule 424(b) if, in the
    aggregate, the changes in volume and price represent no more than a 20
    percent change in the maximum aggregate offering price set forth in the
    "Calculation of Registration Fee" table in the effective registration
    statement.
 
      (iii) To include any material information with respect to the plan of
    distribution not previously disclosed in the Registration Statement or
    any material change to such information in the Registration Statement;
 
                                     II-2
<PAGE>
 
    Provided, however, that paragraphs 1(i) and 1(ii) do not apply if the
  information required to be included in a post-effective amendment by those
  paragraphs is contained in periodic reports filed by the Registrant
  pursuant to Section 12(a) or Section 15(d) of the Exchange Act that are
  incorporated by reference in the Registration Statement.
 
    2. That, for the purpose of determining any liability under the
  Securities Act, each such post-effective amendment shall be deemed to be a
  new registration statement relating to the securities offered therein, and
  the offering of such securities at that time shall be deemed to be the
  initial bona fide offering thereof.
 
    3. To remove from registration by means of a post-effective amendment any
  of the securities being registered which remain unsold at the termination
  of the offering.
 
    4. That, for purposes of determining any liability under the Securities
  Act, each filing of the Registrant's annual report pursuant to Section
  13(a) or Section 15(d) of the Exchange Act that is incorporated by
  reference in this Registration Statement shall be deemed to be a new
  registration statement relating to the securities offered therein, and the
  offering of such securities at that time shall be deemed to be the initial
  bona fide offering thereof.
 
    5. That, prior to any public reoffering of the securities registered
  hereunder through the use of a prospectus which is a part of this
  Registration Statement, by any person or party who is deemed to be an
  underwriter within the meaning of Rule 145(c), the issuer undertakes that
  such reoffering prospectus will contain the information called for by the
  applicable registration form with respect to reofferings by persons who may
  be deemed underwriters, in addition to the information called for by the
  other items of the applicable form.
 
  The Registrant undertakes that every prospectus: (i) that is filed pursuant
to the immediately preceding paragraph, or (ii) that purports to meet the
requirements of Section 10(a)(3) of the Securities Act and is used in
connection with an offering of securities subject to Rule 415, will be filed
as a part of an amendment to the Registration Statement and will not be used
until such amendment is effective, and that, for purposes of determining any
liability under the Securities Act, each such post-effective amendment shall
be deemed to be a new registration statement relating to the securities
offered therein, and the offering of such securities at that time shall be
deemed to be the initial bona fide offering thereof.
 
  (b) The undersigned Registrant hereby undertakes to respond to requests for
information that is incorporated by reference into the Joint Proxy
Statement/Prospectus pursuant to Items 4, 10(b), 11 or 13 of this Form, within
one business day of receipt of such request, and to send the incorporated
documents by first-class mail or other equally prompt means. This includes
information contained in documents filed subsequent to the effective date of
the Registration Statement through the date of responding to the request.
 
  (c) The undersigned Registrant hereby undertakes to supply by means of a
post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in the Registration Statement when it became effective.
 
  Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
Registrant pursuant to Item 20 of this Registration Statement, or otherwise,
the Registrant has been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
in the Securities Act and is, therefore, unenforceable. In the event that a
claim for indemnification against such liabilities (other than the payment by
the Registrant of expenses incurred or paid by a director, officer or
controlling person of the Registrant in the successful defense of any action,
suit or proceeding) is asserted by such director, officer or controlling
person in connection with the securities being registered, the Registrant
will, unless in the opinion of its counsel the matter has been settled by
controlling precedent, submit to a court of appropriate jurisdiction the
question whether such indemnification by it is against public policy as
expressed in the Securities Act and will be governed by the final adjudication
of such issue.

          Re:  Up To 41,015,000 Shares of Common Stock of Rite Aid Corporation
               (the "Company") Issued in Connection With the Merger of the
               Thrifty PayLess Holdings, Inc. ("Thrifty PayLess") Into the
               Company

Ladies and Gentlemen:

          I have acted as counsel for the Company in connection with an
Agreement and Plan of Merger (the "Merger Agreement") dated as of October 13,
1996, between the Company and Thrifty PayLess, pursuant to which Thrifty PayLess
will be merged with and into the Company.  In connection with the Merger
Agreement, the Company has filed with the Securities and Exchange Commission,
pursuant to the Securities Act of 1933 (the "Securities Act"), a Registration
Statement on Form S-4 (the "Registration Statement") relating to up to
41,015,000 shares of Common Stock, par value $1.00 per share, of the Company
(the "Shares") to be issued in connection with the Merger.

          I have examined such documents, records, and matters of law as I have
deemed necessary for purposes of this opinion, and based thereupon I am of the
opinion that the Shares are duly authorized and, when issued and delivered
pursuant to the Merger Agreement as provided therein, will be validly issued,
fully paid and nonassessable.

          I hereby consent to the filing of this opinion as an exhibit to the
Registration Statement.  In giving such consent, I do not thereby admit that I
am within the category of persons whose consent is required under Section 7 of
the Securities Act or the rules and regulations promulgated thereunder.

                              Very truly yours,

Gentlemen and Madame:

Reference is made to our opinion letter dated October 13, 1996 with respect to 
the fairness to the holders of the outstanding shares of Class A Common Stock, 
par value $0.01 per share, and Class B Common Stock, par value $0.01 per share

Dear Stockholder:
   
  You are cordially invited to attend the Special Meeting of Stockholders of
Rite Aid Corporation to be held at the Holiday Inn Harrisburg East, 4751
Lindle Road, Harrisburg, Pennsylvania, on Thursday, December 12, 1996, at 9:30
a.m., Eastern Time.     
   
  At the Rite Aid Special Meeting, stockholders will be asked to adopt the
Agreement and Plan of Merger between Rite Aid and Thrifty PayLess Holdings,
Inc., as amended (the "Merger Agreement"), and the issuance of Rite Aid Common
Stock to Thrifty PayLess stockholders pursuant thereto. The Merger Agreement
provides for the merger of Thrifty PayLess with and into Rite Aid. In the
Merger, Thrifty PayLess Common Stock will be converted into Rite Aid Common
Stock based on an exchange ratio of 0.65 shares of Rite Aid Common Stock for
each share of Thrifty PayLess Common Stock. In addition, pursuant to the
Merger Agreement, Rite Aid's Certificate of Incorporation will be amended in
order, among other things, to increase the number of shares of authorized Rite
Aid Common Stock from 240 million to 300 million.     
 
  The Merger, the Merger Agreement and the terms and conditions thereof are
more fully described in the accompanying Joint Proxy Statement/Prospectus. We
urge you to review this material carefully.
 
  Rite Aid's Board of Directors has unanimously determined that the Merger and
the transactions contemplated by the Merger Agreement are fair to and in the
best interests of the stockholders of Rite Aid, has approved the Merger
Agreement and recommends that Rite Aid stockholders vote "for" adoption of the
Merger Agreement.
 
  The acquisition of Thrifty PayLess is an integral part of Rite Aid's
strategy to operate drug stores in large, fast-growing metropolitan areas.
During fiscal 1998, we plan to close the Thrifty PayLess headquarters in
Wilsonville, Oregon. This closing combined with increased purchasing
efficiencies should enhance Rite Aid's earnings for the year. In addition,
Rite Aid intends to rapidly install its proprietary technology into all
Thrifty PayLess stores. Over the next three years, we anticipate that the
results at the Thrifty PayLess stores will more closely mirror the Rite Aid
stores. The combined company will operate over 3,500 stores and have revenues
greater than $10 billion. Our emphasis on technology and marketing are
designed to position us as an attractive provider to managed care
organizations.
 
  It is important that your shares of Rite Aid Common Stock are represented at
the Special Meeting, regardless of the number of shares you hold. Whether or
not you plan to attend the Special Meeting, please sign, date and return your
proxy card in the enclosed postage paid envelope as soon as possible. If you
later decide to attend the Special Meeting and vote in person, or if you wish
to revoke your proxy for any reason prior to the vote at the Special Meeting,
you may do so and your proxy will have no further effect. If you attend the
Special Meeting, you may vote in person, if you wish, even though you
previously mailed your proxy.
   
  As previously announced, Rite Aid is redeeming the so-called poison pill
rights previously declared in respect of Rite Aid Common Stock. Accordingly, a
check in payment of the redemption price ($0.01 per share of Common Stock
owned of record as of November 12, 1996) will be mailed under separate cover.
Rite Aid has been advised by its legal counsel that such amounts will be
treated as dividend income for federal income tax purposes.     
 
                                          Sincerely,
 
                                          /s/ Martin L. Grass

                           NOVEMBER 12, 1996     
 
Dear Stockholder:
   
  You are cordially invited to attend the Special Meeting of Stockholders of
Thrifty PayLess Holdings, Inc. to be held at The Sheraton Grande Hotel, Caucus
Room, 333 South Figueroa Street, Los Angeles, California on December 12, 1996
at 9:00 a.m., Pacific Standard Time.     
   
  The purpose of the Thrifty PayLess Special Meeting is to consider a proposal
to approve and adopt an Agreement and Plan of Merger, dated as of October 13,
1996, as amended, between Thrifty PayLess and Rite Aid Corporation. The Merger
Agreement provides for Thrifty PayLess' acquisition by Rite Aid through the
merger of Thrifty PayLess into Rite Aid, with Rite Aid surviving the merger,
and related transactions.     
 
  Pursuant to the merger, each share of Class A Common Stock and Class B
Common Stock of Thrifty PayLess (other than shares owned by Thrifty PayLess as
treasury stock, shares held by Rite Aid or any wholly owned subsidiary of Rite
Aid or Thrifty PayLess, and shares of Class A Common Stock as to which
appraisal rights have been properly exercised and perfected) will, by virtue
of the merger and without any action on the part of the holder thereof, be
converted into the right to receive 0.65 shares of duly authorized, validly
issued, fully paid and nonassessable Common Stock of Rite Aid (the "Exchange
Ratio"), which shares will be listed on the New York Stock Exchange. In
addition, upon consummation of the merger, each outstanding option or warrant
to purchase shares of Thrifty PayLess Common Stock will be accelerated and
converted automatically into a right to receive an amount of cash equal to (i)
65% of the closing sales price per share of Rite Aid Common Stock on the New
York Stock Exchange as reported on the New York Stock Exchange Composite Tape
for the date on which the merger becomes effective, minus the exercise price
per share under the applicable option or warrant, times (ii) the number of
shares of Thrifty PayLess Common Stock purchasable upon exercise of such
option or warrant. The obligation of Thrifty PayLess to consummate the merger
is subject, at Thrifty PayLess' option, to a minimum price condition with
respect to the Rite Aid Common Stock and certain other conditions, as
described more fully in the enclosed Joint Proxy Statement/Prospectus.
 
  Your Board of Directors, by unanimous vote, approved the Merger Agreement
and the transactions contemplated thereby (including the merger) as being in
the best interests of Thrifty PayLess and its stockholders. ACCORDINGLY, YOUR
BOARD OF DIRECTORS RECOMMENDS THAT YOU VOTE "FOR" ADOPTION OF THE MERGER
AGREEMENT AND THE TRANSACTIONS CONTEMPLATED THEREBY (INCLUDING THE MERGER).
Our recommendation and our reasons for it, as well as the background of the
transaction, certain risks associated therewith, required regulatory approvals
and other conditions to closing and other important information regarding the
transaction are set forth in the accompanying Joint Proxy
Statement/Prospectus.
 
  Rite Aid has entered into a Stockholder Agreement with each of Thrifty
PayLess' two largest stockholders, Green Equity Investors, L.P. and Kmart
Corporation, pursuant to which such stockholders have each agreed, among other
things, to vote all shares of Thrifty PayLess Common Stock owned by each of
them in favor of adoption of the Merger Agreement and the transactions
contemplated thereby. As of the date of this letter, such stockholders own an
aggregate of 24,998,513 shares, or approximately 42%, of outstanding Thrifty
PayLess Common Stock.
 
  Your vote is important, regardless of the number of shares you own. Adoption
of the Merger Agreement and the transactions contemplated thereby requires the
affirmative vote of the holders of a majority of the outstanding shares of
Thrifty PayLess Class A Common Stock and Class B Common Stock, voting together
as a single class. Accordingly, whether or not you plan to attend the Thrifty
PayLess Special Meeting, you are urged 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 Thrifty PayLess Special
Meeting or voting in person, but will assure that your vote is counted if you
are unable to attend such 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 Thrifty PayLess at Thrifty
PayLess' principal executive offices prior to the Thrifty PayLess Special
Meeting or by attending the Thrifty PayLess Special Meeting and voting in
person.
 
                                      Sincerely,
 
                                      /s/ Leonard I. Green
