To the Holders of Shares of Common Stock
of Hi-Lo Automotive, Inc.:
 
                                 INTRODUCTION
 
  Shamrock Acquisition, Inc. ("Purchaser"), a Delaware corporation and a
wholly owned subsidiary of O'Reilly Automotive, Inc., a Missouri corporation
("Parent"), hereby offers to purchase all outstanding shares of the Common
Stock, par value $.01 per share (the "Common Stock"), including the associated
preferred stock purchase rights (the "Rights" and together with the Common
Stock, the "Shares") issued pursuant to the Rights Agreement (as defined
below), of Hi-Lo Automotive, Inc., a Delaware corporation (the "Company"), at
a price of $4.35 per Share, net to the seller in cash, without interest (the
"Offer Price"), upon the terms and subject to the conditions set forth in this
Offer to Purchase and in the related Letter of Transmittal (which, as amended
or supplemented from time to time, together constitute the "Offer").
 
  Tendering stockholders will not be obligated to pay brokerage fees or
commissions or, except as set forth in Instruction 6 of the Letter of
Transmittal, transfer taxes on the purchase of Shares pursuant to the Offer.
The Parent will pay all fees and expenses of Donaldson, Lufkin & Jenrette
Securities Corporation, as Dealer Manager (in such capacity, the "Dealer
Manager"), ChaseMellon Shareholder Services, L.L.C., as Depositary (the
"Depositary"), and Innisfree M&A Incorporated, as Information Agent (the
"Information Agent"), incurred in connection with the Offer. See Section 16.
 
  THE BOARD OF DIRECTORS OF THE COMPANY (THE "COMPANY BOARD") HAS UNANIMOUSLY
APPROVED THE OFFER AND THE MERGER AND THE MERGER AGREEMENT (AS DEFINED BELOW)
AND THE MERGER AGREEMENT (AS DEFINED BELOW), HAS DETERMINED THAT THE TERMS OF
THE OFFER AND THE MERGER ARE FAIR TO, AND IN THE BEST INTERESTS OF, THE
COMPANY AND ITS STOCKHOLDERS, AND RECOMMENDS THAT STOCKHOLDERS ACCEPT THE
OFFER AND TENDER THEIR SHARES.
 
  SBC Warburg Dillon Read, Inc. ("SBC Warburg Dillon Read"), the Company's
financial advisor, has delivered to the Company Board its written opinion that
the consideration to be received by the stockholders of the Company pursuant
to each of the Offer and the Merger is fair to such stockholders. A copy of
the opinion of SBC Warburg Dillon Read is contained in the Company's
Solicitation/Recommendation Statement on Schedule 14D-9 (the "Schedule
14D-9"), which is being mailed to stockholders herewith.
 
  THE OFFER IS CONDITIONED UPON, AMONG OTHER THINGS, THERE BEING VALIDLY
TENDERED AND NOT WITHDRAWN PRIOR TO THE EXPIRATION OF THE OFFER A NUMBER OF
SHARES WHICH, TOGETHER WITH ANY SHARES BENEFICIALLY OWNED BY PARENT OR
PURCHASER, REPRESENT AT LEAST A MAJORITY OF THE SHARES OUTSTANDING ON A FULLY
DILUTED BASIS (THE "MINIMUM CONDITION"). The Company has represented and
warranted to the Purchaser and Parent in the Merger Agreement that, as of
December 15, 1997, 10,775,109 Shares were issued and outstanding, and 507,223
Shares were issuable pursuant to options ("Options"), excluding 587,566 shares
issuable upon the exercise of options which the Company's directors and
executive officers have agreed not to exercise, granted under the Company's
option plans and pursuant to the Associate Purchase Plan (as defined in
Section 12). Based on the foregoing and assuming no additional Shares (or
options, warrants or rights exercisable for, or convertible securities
convertible into Shares) have been issued since December 15, 1997 (other than
Shares issued pursuant to the exercise of the stock options referred to
above), if 5,641,167 Shares were validly tendered and not withdrawn prior to
the Expiration Date (as hereinafter defined) pursuant to the terms of the
Offer, the Minimum Condition would be satisfied.
 
  CERTAIN OTHER CONDITIONS TO CONSUMMATION OF THE OFFER ARE DESCRIBED IN
SECTION 14. THE PURCHASER EXPRESSLY RESERVES THE RIGHT TO WAIVE ANY ONE OR
MORE OF THE CONDITIONS TO THE OFFER (EXCEPT THAT THE MINIMUM CONDITION MAY NOT
BE WAIVED WITHOUT THE COMPANY'S CONSENT). SEE SECTION 14.
<PAGE>
 
  The Offer is being made pursuant to an Agreement and Plan of Merger, dated
as of December 23, 1997 (the "Merger Agreement"), among Parent, Purchaser and
the Company. The Merger Agreement provides that, among other things, as soon
as practicable after the purchase of Shares pursuant to the Offer and the
satisfaction of the other conditions set forth in the Merger Agreement and in
accordance with the relevant provisions of the Delaware General Corporation
Law (the "DGCL"), Purchaser will be merged with and into the Company (the
"Merger"). Following consummation of the Merger, the Company will continue as
the surviving corporation (the "Surviving Corporation") as a wholly owned
subsidiary of Parent. At the effective time of the Merger (the "Effective
Time"), each Share issued and outstanding immediately prior to the Effective
Time (other than Shares owned by Purchaser, Parent, the Company or any wholly
owned subsidiary of Parent or the Company and Shares held by stockholders who
perfect their dissenters' rights under Delaware law) will be cancelled and
converted automatically into the right to receive $4.35 in cash, or any higher
price that may be paid per Share in the Offer, without interest (the "Merger
Consideration"). The Merger Agreement is more fully described in Section 12.
 
  The Merger Agreement provides that, upon the purchase by Purchaser of a
majority of the Shares pursuant to the Offer and from time to time thereafter,
Parent shall be entitled to designate such number of directors, rounded up to
the next whole number, on the Company Board so that the percentage of Parent's
nominees on the Company Board equals the percentage of outstanding Shares
beneficially owned by Parent and its affiliates. The Company shall, at such
time, upon the request of Purchaser promptly use its best efforts to take all
action necessary to cause such persons designated by Parent to be elected to
the Company Board, if necessary, by increasing the size of the Company Board
or securing resignations of incumbent directors or both.
 
  Under the DGCL, if the Purchaser acquires, pursuant to the Offer or
otherwise, at least 90% of the outstanding Shares, the Purchaser will be able
to approve the Merger Agreement and the transactions contemplated thereby
without a vote of the stockholders. In such event, Parent, Purchaser and the
Company have agreed in the Merger Agreement to take, at the request of Parent
and subject to the satisfaction of the conditions set forth in the Merger
Agreement, all necessary and appropriate action to cause the Merger to become
effective as soon as reasonably practicable after such acquisition, without a
meeting of the stockholders, in accordance with Section 253 of the DGCL. If,
however, the Purchaser does not acquire at least 90% of the outstanding Shares
pursuant to the Offer or otherwise and a vote of the stockholders is required
under the DGCL, a significantly longer period of time would be required to
effect the Merger. In the Merger Agreement, Parent, Purchaser and the Company
have agreed that, notwithstanding that all conditions to the Offer are
satisfied or waived as of the scheduled Expiration Date, Purchaser may extend
the Offer for a period not to exceed 10 business days, subject to certain
conditions, if the Shares tendered pursuant to the Offer are less than 90% of
the outstanding Shares.
 
  The Rights. The Company has distributed one Right for each outstanding Share
of Common Stock pursuant to the Rights Agreement, dated as of August 28, 1996,
between the Company and ChaseMellon Shareholder Services, L.L.C., as Rights
Agent, as amended (the "Rights Agreement"). Based on the information disclosed
by the Company in the Schedule 14D-9 in connection with and prior to the
Company's entering into the Merger Agreement, on December 23, 1997, the
Company Board approved an amendment to the Rights Agreement to provide that
the execution of the Merger Agreement and the consummation of the transactions
contemplated thereby will not cause (i) Parent and/or the Purchaser to become
an Acquiring Person (as defined in the Rights Agreement) or (ii) a
Distribution or a Shares Acquisition Date (as each such term is defined in the
Rights Agreement) to occur, irrespective of the number of Shares acquired
pursuant to the Offer.
 
  THIS OFFER TO PURCHASE AND THE LETTER OF TRANSMITTAL CONTAIN IMPORTANT
INFORMATION WHICH SHOULD BE READ CAREFULLY BEFORE ANY DECISION IS MADE WITH
RESPECT TO THE OFFER.

                               THE TENDER OFFER
 
  1. TERMS OF THE OFFER.
 
  Upon the terms and subject to the conditions of the Offer (including, if the
Offer is extended or amended, the terms and conditions of any such extension
or amendment), the Purchaser will accept for payment and pay for all Shares
validly tendered prior to the Expiration Date and not properly withdrawn in
accordance with the procedures set forth in Section 4. The term "Expiration
Date" means 12:00 Midnight, New York City time, on Monday, January 26, 1998,
unless and until the Purchaser shall have extended the period of time during
which the Offer is open, subject to the terms of the Merger Agreement, in
which event the term "Expiration Date" shall mean the latest time and date at
which the Offer, as so extended by the Purchaser, shall expire. If requested
by the Company, the Purchaser is required to extend the Offer from time to
time until 90 days after commencement of the Offer if on the scheduled
Expiration Date any of the conditions to Purchaser's obligation to accept for
payment and pay for the Shares shall not be satisfied or waived.
 
  Consummation of the Offer is conditioned upon satisfaction of the Minimum
Condition, the expiration or termination of all waiting periods imposed by the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, and the
regulations thereunder (the "HSR Act") and the other conditions set forth in
Section 14. If such conditions are not satisfied prior to the Expiration Date,
the Purchaser reserves the right, but shall not be obligated, to decline to
purchase any of the Shares tendered, delay the acceptance for payment of any
Shares or terminate or amend the Offer, subject to the terms of the Merger
Agreement. Subject to the terms and conditions contained in the Merger
Agreement, the Purchaser reserves the right (but shall not be obligated) to
waive in whole or in part, at any time and from time to time, any or all of
such conditions, provided that the Minimum Condition cannot be waived by the
Purchaser without the written consent of the Company. In the Merger Agreement,
Parent, Purchaser and the Company have agreed that, notwithstanding that all
conditions to the Offer are satisfied or waived as of the scheduled Expiration
Date, Purchaser may extend the Offer, subject to certain conditions as set
forth in the Merger Agreement, (i) for a period not to exceed 10 business days
if the Shares tendered pursuant to the Offer are less than 90% of the
outstanding Shares and (ii) for a period not to exceed five business days, if
an Adverse Market Change (as hereinafter defined) shall have occurred and be
continuing on the scheduled Expiration Date. See Section 12.
 
  Pursuant to the Merger Agreement, the Purchaser may not, without the written
consent of the Company, (i) decrease the price per Share payable in the Offer,
(ii) change the form of consideration to be paid in the Offer, (iii) reduce
the maximum number of Shares to be purchased in the Offer or the Minimum
Condition, (iv) impose additional conditions to the Offer or modify the
conditions in a manner adverse to the holders of Shares or (v) amend any other
term of the Offer in a manner adverse to the holders of the Shares. Subject to
the terms and conditions of the Offer and this Agreement, Purchaser shall, and
Parent shall cause Purchaser to, pay for all Shares validly tendered and not
withdrawn pursuant to the Offer that Purchaser becomes obligated to purchase
pursuant to the Offer as soon as practicable after the expiration of the
Offer.
 
  There can be no assurance that either the Company or the Purchaser will
exercise its rights to cause the Purchaser to extend the Offer (other than as
required by the Merger Agreement or applicable law). Any extension, amendment
or termination of the Offer, or any waiver of any condition of the Offer, will
be followed as promptly as practicable by a public announcement. In the case
of an extension, Rule 14e-1(d) under the Securities Exchange Act of 1934, as
amended (the "Exchange Act"), requires that the announcement be issued no
later than 9:00 a.m., New York City time, on the next business day after the
previously scheduled Expiration Date in accordance with the public
announcement requirements of Rule 14d-4(c) under the Exchange Act. As used in
this Offer to Purchase, "business day" has the meaning set forth in Rule 14d-1
under the Exchange Act. Subject to applicable law (including Rules 14d-4(c)
and 14d-6(d) under the Exchange Act, which require that any material change in
the information published, sent or given to stockholders in connection with
the Offer be promptly disseminated to stockholders in a manner reasonably
designed to inform stockholders of such change), and without limiting the
manner in which the Purchaser may choose to make any public announcement, the
 
                                       3
<PAGE>
 
Purchaser will not have any obligation to publish, advertise or otherwise
communicate any such public announcement other than by making a release to the
Dow Jones News Service. During any extension of the Offer, all Shares
previously tendered and not properly withdrawn will remain subject to the
Offer, subject to the rights of a tendering stockholder to withdraw its Shares
in accordance with the procedures set forth in Section 4. THE PURCHASER SHALL
NOT HAVE ANY OBLIGATION TO PAY INTEREST ON THE PURCHASE PRICE FOR TENDERED
SHARES, WHETHER OR NOT THE PURCHASER EXERCISES ITS RIGHT TO EXTEND THE OFFER.
 
  If the Purchaser extends the Offer or if the Purchaser is delayed in its
acceptance for payment of or payment for Shares (whether before or after its
acceptance for payment of Shares) or it is unable to pay for Shares pursuant to
the Offer for any reason, then, without prejudice to the Purchaser's rights
under the Offer, the Depositary may retain tendered Shares on behalf of the
Purchaser, and such Shares may not be withdrawn except to the extent tendering
stockholders are entitled to withdrawal rights as described in Section 4.
However, the ability of the Purchaser to delay the payment for Shares that the
Purchaser has accepted for payment is limited by Rule 14e-1(c) under the
Exchange Act, which requires that a bidder pay the consideration offered or
return the securities deposited by or on behalf of holders of securities
promptly after the termination or withdrawal of such bidder's offer.
 
  If the Purchaser makes a material change in the terms of the Offer or the
information concerning the Offer or waives a material condition of the Offer
(including, subject to the Merger Agreement, the Minimum Condition), the
Purchaser will disseminate additional tender offer materials and extend the
Offer to the extent required by Rules 14d-4(c), 14d-6(d) and 14e-1 under the
Exchange Act. The minimum period during which an offer must remain open
following a material change in the terms of the offer or information concerning
the offer, other than a change in price or a change in the percentage of
securities sought, will depend upon the facts and circumstances then existing,
including the relative materiality of the changed terms or information. In a
public release, the Securities and Exchange Commission (the "Commission") has
stated that in its view an offer must remain open for a minimum period of time
following a material change in the terms of the Offer and that waiver of a
material condition, such as the Minimum Condition, is a material change in the
terms of the Offer. The release states that an offer should remain open for a
minimum of five business days from the date a material change is first
published, sent or given to security holders and that, if material changes are
made with respect to information not materially less significant than the offer
price and the number of shares being sought, a minimum of ten business days may
be required to allow adequate dissemination and investor response. The
requirement to extend the Offer will not apply to the extent that the number of
business days remaining between the occurrence of the change and the then-
scheduled Expiration Date equals or exceeds the minimum extension period that
would be required because of such amendment. If, prior to the Expiration Date,
the Purchaser increases the consideration offered to holders of Shares pursuant
to the Offer, such increased consideration will be paid to all holders whose
Shares are purchased in the Offer whether or not such Shares were tendered
prior to such increase in consideration.
 
  The Company has provided the Purchaser with the Company's stockholder lists
and security position listing for the purpose of disseminating the Offer to
holders of the Shares. This Offer to Purchase, the related Letter of
Transmittal and other relevant materials will be mailed by the Purchaser to
record holders of Shares and will be furnished by the Purchaser to brokers,
dealers, banks, trust companies and similar persons whose names, or the names
of whose nominees, appear on the stockholder lists or, if applicable, who are
listed as participants in a clearing agency's security position listing, for
subsequent transmittal to beneficial owners of Shares.
 
  2. ACCEPTANCE FOR PAYMENT AND PAYMENT FOR SHARES.
 
  Upon the terms and subject to the conditions of the Offer (including, if the
Offer is extended or amended, the terms and conditions of any such extension or
amendment), the Purchaser will purchase, by accepting for payment, and will pay
for, as soon as it is permitted to do so under applicable law, all Shares
validly tendered prior to the Expiration Date and not properly withdrawn in
accordance with the procedures set forth in Section 4. All determinations
concerning the satisfaction of such terms and conditions will be within the
Purchaser's
 
                                       4
<PAGE>
 
reasonable discretion, which determinations will be final and binding. See
Sections 1 and 14. The Purchaser expressly reserves the right, in its sole
discretion, to delay acceptance for payment of or payment for Shares in order
to comply in whole or in part with any applicable law, including, without
limitation, the HSR Act.
 
  Any such delays will be effected in compliance with Rule 14e-1(c) promulgated
under the Exchange Act (relating to a bidder's obligation to pay for or return
tendered securities promptly after the termination or withdrawal of such
bidder's offer). In all cases, payment for Shares purchased pursuant to the
Offer will be made only after timely receipt by the Depositary of (i) the
certificates evidencing such Shares (the "Share Certificates") or timely
confirmation of a book-entry transfer (a "Book-Entry Confirmation") of such
Shares into the Depositary's account at The Depository Trust Company or the
Philadelphia Depository Trust Company (collectively, the "Book-Entry Transfer
Facilities") pursuant to the procedures set forth in Section 3, (ii) the Letter
of Transmittal (or facsimile thereof), properly completed and duly executed,
with any required signature guarantees, or, in the case of a book-entry
transfer, an Agent's Message (as defined below) and (iii) any other documents
required by the Letter of Transmittal.
 
  The term "Agent's Message" means a message, transmitted by a Book-Entry
Transfer Facility to, and received by, the Depositary and forming a part of a
Book-Entry Confirmation, which states that such Book-Entry Transfer Facility
has received an express acknowledgment from the participant in such Book-Entry
Transfer Facility tendering the Shares which are the subject of such Book-Entry
Confirmation, that such participant has received and agrees to be bound by the
terms of the Letter of Transmittal and that the Purchaser may enforce such
agreement against the participant.
 
  For purposes of the Offer, the Purchaser shall be deemed to have accepted for
payment, and thereby purchased, Shares validly tendered prior to the Expiration
Date and not properly withdrawn if, as and when the Purchaser gives oral or
written notice to the Depositary of the Purchaser's acceptance of such Shares
for payment pursuant to the Offer. Upon the terms and subject to the conditions
of the Offer, payment for Shares accepted pursuant to the Offer will be made by
deposit of the aggregate purchase price therefor with the Depositary, which
will act as agent for tendering stockholders for the purpose of receiving
payment from the Purchaser and transmitting payment to such tendering
stockholders. Under no circumstances will interest on the purchase price for
Shares be paid regardless of any extension of the Offer or any delay in making
such payment. Upon the deposit of funds with the Depositary for the purpose of
making payments to tendering stockholders, the Purchaser's obligation to make
such payment shall be satisfied and tendering stockholders must thereafter look
solely to the Depositary for payment of amounts owed to them by reason of the
acceptance for payment of Shares pursuant to the Offer. Tendering stockholders
will not be obligated to pay brokerage fees or commissions or, except as set
forth in Instruction 6 of the Letter of Transmittal, transfer taxes on the
purchase of Shares pursuant to the Offer. The Purchaser will pay any charges
and expenses of the Depositary and the Information Agent.
 
  If any tendered Shares are not accepted for payment for any reason pursuant
to the terms and conditions of the Offer, or if Share Certificates are
submitted evidencing more Shares than are tendered, Share Certificates
evidencing such unpurchased Shares or untendered Shares will be returned,
without expense to the tendering stockholder (or, in the case of Shares
tendered by book-entry transfer into the Depositary's account at a Book-Entry
Transfer Facility pursuant to the procedures set forth in Section 3, such
Shares will be credited to an account maintained at such Book-Entry Transfer
Facility), as promptly as practicable following the expiration, termination or
withdrawal of the Offer.
 
  The Purchaser reserves the right to transfer or assign, in whole at any time,
or in part from time to time, to one or more of its affiliates, the right to
purchase all or any portion of the Shares tendered pursuant to the Offer, but
any such transfer or assignment will not relieve the Purchaser of its
obligations under the Offer or prejudice the rights of tendering stockholders
to receive payment for Shares validly tendered and accepted for payment
pursuant to the Offer.

  3. PROCEDURES FOR TENDERING SHARES.
 
  Valid Tender of Shares. In order for Shares to be validly tendered pursuant
to the Offer, the Letter of Transmittal or a facsimile thereof, properly
completed and duly executed, with any required signature guarantees, or an
Agent's Message in connection with a book-entry delivery of Shares, and any
other required documents, must be received by the Depositary at one of its
addresses set forth on the back cover of this Offer to Purchase prior to the
Expiration Date and either (i) the Share Certificates evidencing tendered
Shares must be received by the Depositary along with the Letter of Transmittal,
or (ii) Shares must be tendered pursuant to the procedure for book-entry
transfer described below and a Book-Entry Confirmation must be received by the
Depositary, or (iii) the tendering stockholder must comply with the guaranteed
delivery procedures described below, in each case prior to the Expiration Date.
 
  THE METHOD OF DELIVERY OF SHARE CERTIFICATES, THE LETTER OF TRANSMITTAL AND
ALL OTHER REQUIRED DOCUMENTS, INCLUDING DELIVERY THROUGH ANY BOOK-ENTRY
TRANSFER FACILITY, IS AT THE OPTION AND RISK OF THE TENDERING STOCKHOLDER, AND
THE DELIVERY THEREOF WILL BE DEEMED MADE ONLY WHEN ACTUALLY RECEIVED BY
THE DEPOSITARY. IF DELIVERY IS BY MAIL, REGISTERED MAIL WITH RETURN RECEIPT
REQUESTED, PROPERLY INSURED, IS RECOMMENDED. IN ALL CASES, SUFFICIENT TIME
SHOULD BE ALLOWED TO ENSURE TIMELY DELIVERY.
 
  Book-Entry Transfer. The Depositary will establish an account with respect to
the Shares at each Book-Entry Transfer Facility for purposes of the Offer
within two business days after the date of this Offer to Purchase, and any
financial institution that is a participant in any of the Book-Entry Transfer
Facilities' systems may make book-entry delivery of Shares by causing a Book-
Entry Transfer Facility to transfer such Shares into the Depositary's account
at a Book-Entry Transfer Facility in accordance with such Book-Entry Transfer
Facility's procedures for transfer. However, although delivery of Shares may be
effected through book-entry transfer at a Book-Entry Transfer Facility, the
Letter of Transmittal (or facsimile thereof), properly completed and duly
executed and with any required signature guarantees, or an Agent's Message in
connection with a book-entry delivery of Shares, and any other required
documents, must, in any case, be transmitted to, and received by, the
Depositary at one of its addresses set forth on the back cover of this Offer to
Purchase prior to the Expiration Date or the tendering stockholder must comply
with the guaranteed delivery procedures described below. DELIVERY OF DOCUMENTS
TO A BOOK-ENTRY TRANSFER FACILITY IN ACCORDANCE WITH SUCH BOOK-ENTRY TRANSFER
FACILITY'S PROCEDURES DOES NOT CONSTITUTE DELIVERY TO THE DEPOSITARY.
 
  Signature Guarantees. Signatures on all Letters of Transmittal must be
guaranteed by a firm which is a bank, broker, dealer, credit union, savings
association or other entity that is a member in good standing of the Securities
Transfer Agents Medallion Program (each of the foregoing being referred to as
an "Eligible Institution"), unless the Shares tendered thereby are tendered (i)
by a registered holder of Shares who has not completed either the box entitled
"Special Delivery Instructions" or the box entitled "Special Payment
Instructions" on the Letter of Transmittal or (ii) for the account of an
Eligible Institution. See Instruction 1 of the Letter of Transmittal.
 
  If a Share Certificate is registered in the name of a person other than the
signer of the Letter of Transmittal, or if payment is to be made, or a Share
Certificate not accepted for payment or not tendered is to be returned to a
person other than the registered holder(s), then the Share Certificate must be
endorsed or accompanied by appropriate stock powers, in either case signed
exactly as the name(s) of the registered holder(s) appear on the Share
Certificate, with the signature(s) on such Share Certificate or stock powers
guaranteed as described above. See Instructions 1 and 5 of the Letter of
Transmittal.
 
  Guaranteed Delivery. If a stockholder desires to tender Shares pursuant to
the Offer and such stockholder's Share Certificates are not immediately
available or time will not permit all required documents to reach the

Depositary prior to the Expiration Date or the procedure for book-entry
transfer cannot be completed on a timely basis, such Shares may nevertheless be
tendered if all the following conditions are satisfied:
 
    (i) the tender is made by or through an Eligible Institution;
 
    (ii) a properly completed and duly executed Notice of Guaranteed
  Delivery, substantially in the form provided by the Purchaser herewith, is
  received by the Depositary, as provided below, prior to the Expiration
  Date; and
 
    (iii) the Share Certificates for all tendered Shares, in proper form for
  transfer, or a Book-Entry Confirmation, together with a properly completed
  and duly executed Letter of Transmittal (or manually signed facsimile
  thereof) with any required signature guarantee (or, in the case of a book-
  entry transfer, an Agent's Message) and any other documents required by
  such Letter of Transmittal, are received by the Depositary within three
  trading days after the date of execution of the Notice of Guaranteed
  Delivery. A "trading day" is any day on which the New York Stock Exchange,
  Inc. ("NYSE") is open for business.
 
  Any Notice of Guaranteed Delivery may be delivered by hand or transmitted by
telegram, facsimile transmission or mail to the Depositary and must include a
guarantee by an Eligible Institution in the form set forth in the Notice of
Guaranteed Delivery.
 
  Notwithstanding any other provision hereof, payment for Shares purchased
pursuant to the Offer will, in all cases, be made only after timely receipt by
the Depositary of (i) the Share Certificates evidencing such Shares, or a Book-
Entry Confirmation of the delivery of such Shares, (ii) a properly completed
and duly executed Letter of Transmittal (or manually signed facsimile thereof)
(or, in the case of a book-entry transfer, an Agent's Message) and (iii) any
other documents required by the Letter of Transmittal. Accordingly, tendering
stockholders may be paid at different times depending upon when the foregoing
materials are actually received by the Depositary. UNDER NO CIRCUMSTANCES WILL
INTEREST BE PAID ON THE PURCHASE PRICE OF THE SHARES TO BE PAID BY THE
PURCHASER, REGARDLESS OF ANY EXTENSION OF THE OFFER OR ANY DELAY IN MAKING SUCH
PAYMENT.
 
  Backup Federal Withholding Tax. To prevent backup federal income tax
withholding with respect to payment to certain stockholders of the purchase
price of Shares purchased pursuant to the Offer, each such stockholder must,
unless an exemption applies, provide the Depositary with such stockholder's
correct taxpayer identification number ("TIN") and certify, under penalty or
perjury, that such TIN is correct and that such stockholder is not subject to
backup federal income tax withholding by completing the Substitute Form W-9
included in the Letter of Transmittal. If a stockholder does not provide such
stockholder's correct TIN or fails to provide the certifications described
above, the Internal Revenue Service (the "IRS") may impose a penalty on such
stockholder and payment of cash to such stockholder pursuant to the Offer may
be subject to backup withholding of 31%. All stockholders surrendering Shares
pursuant to the Offer should complete and sign the main signature form and the
Substitute Form W-9 included as part of the Letter of Transmittal to provide
the information and certification necessary to avoid backup withholding (unless
an applicable exemption exists and is proved in a manner satisfactory to the
Purchaser and the Depositary). Certain stockholders (including, among others,
all corporations and certain foreign individuals and entities) are not subject
to backup withholding. Foreign stockholders, if exempt, should complete and
sign the main signature form and a Form W-8, Certificate of Foreign Status, a
copy of which may be obtained from the Depositary, in order to avoid backup
withholding. See Instruction 9 of the Letter of Transmittal.
 
  Appointment as Proxy; Distributions. By executing a Letter of Transmittal as
set forth above, a tendering stockholder irrevocably appoints designees of the
Purchaser as such stockholder's attorneys-in-fact and proxies, in the manner
set forth in the Letter of Transmittal, each with full power of substitution,
to the full extent of such stockholder's rights with respect to the Shares
tendered by such stockholder and accepted for payment by the Purchaser (and any
and all non-cash dividends, distributions, rights, other Shares, or other
securities issued or issuable in respect of such Shares on or after the date of
the Merger Agreement). All such powers of attorney and proxies shall be
considered coupled with an interest in the tendered Shares. This appointment
will be effective if, when, and only to the extent that, the Purchaser accepts
such Shares for payment pursuant to the
 
                                       7
<PAGE>
 
Offer. Upon such acceptance for payment, all prior powers of attorney and
proxies given by such stockholder with respect to such Shares and other
securities will, without further action, be revoked, and no subsequent powers
of attorney or proxies may be given (and, if given, will not be deemed
effective). The designees of the Purchaser will, with respect to the Shares and
other securities for which the appointment is effective, be empowered to
exercise all voting and other rights of such stockholder as they in their sole
discretion may deem proper at any annual, special, adjourned or postponed
meeting of the Company's stockholders, by written consent or otherwise, and the
Purchaser reserves the right to require that, in order for Shares or other
securities to be deemed validly tendered, immediately upon the Purchaser's
acceptance for payment of such Shares the Purchaser must be able to exercise
full voting, consent and other rights with respect to such Shares and other
securities, including voting at any meeting of stockholders. Such powers of
attorney and proxies will be irrevocable and will be granted in consideration
of the purchase of the Shares by the Purchaser in accordance with the terms of
the Offer.
 
  Determination of Validity. All questions as to the validity, form,
eligibility (including time of receipt) and acceptance for payment of any
tendered Shares pursuant to any of the procedures described above will be
determined by the Purchaser, in its sole discretion, whose determination will
be final and binding on all parties. The Purchaser reserves the absolute right
to reject any or all tenders of any Shares determined by it not to be in proper
form or if the acceptance for payment of, or payment for, such Shares may, in
the opinion of the Purchaser's counsel, be unlawful. The Purchaser also
reserves the absolute right, in its sole discretion, subject to the Merger
Agreement to waive any of the conditions of the Offer or any defect or
irregularity in any tender with respect to Shares of any particular
stockholder, whether or not similar defects or irregularities are waived in the
case of other stockholders. No tender of Shares will be deemed to have been
validly made until all defects and irregularities have been cured or waived.
 
  The Purchaser's interpretation of the terms and conditions of the Offer
(including the Letter of Transmittal and the instructions thereto) will be
final and binding. None of Parent, the Purchaser, the Dealer Manager, the
Depositary, the Information Agent or any other person will be under any duty to
give notification of any defects or irregularities in tenders or will incur any
liability for failure to give any such notification.
 
  Binding Agreement. A tender of Shares pursuant to any of the procedures
described above will constitute the tendering stockholder's acceptance of the
terms and conditions of the Offer. The Purchaser's acceptance for payment of
Shares tendered pursuant to the Offer will constitute a binding agreement
between the tendering stockholder and the Purchaser upon the terms and subject
to the conditions of the Offer.
 
  4. WITHDRAWAL RIGHTS.
 
  Except as otherwise provided in this Section 4, tenders of Shares made
pursuant to the Offer are irrevocable. Shares tendered pursuant to the Offer
may be withdrawn pursuant to the procedures set forth below or at any time
prior to the Expiration Date and, unless theretofore accepted for payment by
the Purchaser pursuant to the Offer, may also be withdrawn at any time after
February 21, 1998.
 
  If the Purchaser extends the Offer, is delayed in its acceptance for payment
of Shares or is unable to accept Shares for payment pursuant to the Offer for
any reason, then, without prejudice to the Purchaser's rights under the Offer,
the Depositary may, nevertheless, on behalf of the Purchaser, retain tendered
Shares, and such Shares may not be withdrawn except to the extent that
tendering stockholders are entitled to withdrawal rights as described in this
Section 4.
 
  For a withdrawal to be effective, a written, telegraphic or facsimile
transmission notice of withdrawal must be timely received by the Depositary at
one of its addresses set forth on the back cover of this Offer to Purchase. Any
such notice of withdrawal must specify the name of the person who tendered the
Shares to be withdrawn, the number of Shares to be withdrawn and the name of
the registered holder, if different from that of the person who tendered such
Shares. If Share Certificates evidencing Shares to be withdrawn have been
delivered or
 
                                       8
<PAGE>
 
otherwise identified to the Depositary, then, prior to the physical release of
such Share Certificates, the serial numbers shown on such Share Certificates
must be submitted to the Depositary and the signature(s) on the notice of
withdrawal must be guaranteed by an Eligible Institution, unless such Shares
have been tendered for the account of an Eligible Institution. If Shares have
been tendered pursuant to the procedure for book-entry transfer as set forth in
Section 3, any notice of withdrawal must also specify the name and number of
the account at the appropriate Book-Entry Transfer Facility to be credited with
the withdrawn Shares and otherwise comply with such Book-Entry Transfer
Facility's procedures.
 
  All questions as to the form and validity (including time of receipt) of
notices of withdrawal will be determined by the Purchaser, in its sole
discretion, whose determination will be final and binding on all parties. None
of Parent, the Purchaser, the Dealer Manager, the Depositary, the Information
Agent or any other person will be under any duty to give notification of any
defects or irregularities in any notice of withdrawal or incur any liability
for failure to give any such notification.
 
  Any Shares properly withdrawn will thereafter be deemed to not have been
validly tendered for purposes of the Offer. Withdrawals of tenders of Shares
may not be rescinded. However, withdrawn Shares may be re-tendered at any time
prior to the Expiration Date by following one of the procedures described in
Section 3 on or prior to the Expiration Date.
 
  5. CERTAIN FEDERAL INCOME TAX CONSEQUENCES.
 
  The following is a summary of certain United States federal income tax
consequences of the Offer and the Merger to stockholders whose Shares are
purchased pursuant to the Offer or whose Shares are converted to cash in the
Merger (including pursuant to the exercise of perfected dissenter rights under
the DGCL). The discussion applies only to stockholders in whose hands Shares
are capital assets, and may not apply to Shares received pursuant to the
exercise of employee stock options or otherwise as compensation, or to
stockholders who are in special tax situations (such as insurance companies,
tax-exempt organizations or dealers in securities). This discussion does not
discuss the federal income tax consequences to a stockholder who, for United
States federal income tax purposes, is a nonresident alien individual, a
foreign corporation, a foreign partnership or a foreign estate or trust.
 
  THE FEDERAL INCOME TAX CONSEQUENCES SET FORTH BELOW ARE INCLUDED FOR GENERAL
INFORMATIONAL PURPOSES ONLY AND ARE BASED UPON CURRENT LAW. BECAUSE INDIVIDUAL
CIRCUMSTANCES MAY DIFFER, EACH STOCKHOLDER SHOULD CONSULT SUCH STOCKHOLDER'S
OWN TAX ADVISOR TO DETERMINE THE APPLICABILITY OF THE RULES DISCUSSED BELOW TO
SUCH STOCKHOLDER AND THE PARTICULAR TAX EFFECTS TO SUCH STOCKHOLDER OF THE
OFFER AND THE MERGER, INCLUDING THE APPLICATION AND EFFECT OF STATE, LOCAL,
FOREIGN AND OTHER INCOME TAX LAWS.
 
  The receipt of cash for Shares pursuant to the Offer or the Merger will be a
taxable transaction for federal income tax purposes (and also may be a taxable
transaction under applicable state, local and other income tax laws). In
general, for federal income tax purposes, a stockholder will recognize gain or
loss in an amount equal to the difference between his or her adjusted tax basis
in the Shares sold pursuant to the Offer or converted into cash in the Merger
and the amount of cash received therefor. Gain or loss must be determined
separately for each block of Shares (i.e., Shares acquired at the same cost in
a single transaction) sold pursuant to the Offer or converted into cash in the
Merger. Such gain or loss will be capital gain or loss if the Shares are held
as a capital asset by the stockholder, and will be long-term gain or loss if
the Shares were held by the stockholder for more than one year on the date of
sale (in the case of the Offer) or the Effective Time of the Merger (in the
case of the Merger). In addition, the recently enacted Taxpayer Relief Act of
1997 could affect the federal income tax consequences of the Offer and the
Merger in that, among other things, it reduces the maximum rate of federal
income tax on capital gains of individual taxpayers for capital assets held
more than eighteen months.

</TABLE>
 
  On December 22, 1997, the last full trading day prior to the public
announcement of the execution of the Merger Agreement and of Purchaser's
intention to commence the Offer, the closing price per Share as reported on the
NYSE was $3 1/4. Stockholders are urged to obtain a current market quotation
for the Shares.
 
  The Company has never paid any cash dividends on the Shares. The Merger
Agreement provides that, without the prior written consent of Parent, the
Company will not declare, set aside or pay any dividend on or make any other
distribution in respect of any of its capital stock. See Section 12.
 
  7. EFFECT OF THE OFFER ON THE MARKET FOR THE SHARES; EXCHANGE LISTING AND
EXCHANGE ACT REGISTRATION; MARGIN REGULATIONS.
 
  Market for the Shares. The purchase of Shares pursuant to the Offer will
reduce the number of Shares that might otherwise trade publicly and could
reduce the number of holders of Shares, which could adversely affect the
liquidity and market value of the remaining Shares held by the public.
 
  Stock Listing. Depending upon the number of Shares purchased pursuant to the
Offer, the Shares may no longer meet the requirements of the NYSE for continued
listing and may be delisted from the NYSE and deregistered under Section 12(b)
of the Exchange Act. Parent intends to cause the delisting by the NYSE and
deregistration of the Shares following consummation of the Offer.
 
  According to the published guidelines, the NYSE would consider delisting the
Shares if, among other things, the number of holders of at least 100 Shares
should fall below 1,200, the number of publicly held Shares (exclusive of
holdings of officers, directors and their families and other concentrated
holdings of 10 percent or more ("NYSE Excluded Holdings")) should fall below
600,000 or the aggregate market value of publicly held Shares (exclusive of
NYSE Excluded Holdings) should fall below $8,000,000. The Company has advised
Purchaser that, as of December 17, 1997, there were 10,775,109 Shares
outstanding, held by approximately 430 holders of record. If, as a result of
the purchase of Shares pursuant to the Offer or otherwise, the Shares no longer
meet the requirements of the NYSE for continued listing and the listing of the
Shares is discontinued, the market for the Shares could be adversely affected.
 
                                       10
<PAGE>
 
  If the NYSE were to delist the Shares, it is possible that the Shares would
continue to trade on another securities exchange or in the over the counter
market and that price or other quotations would be reported by such exchange or
through the Nasdaq Stock Market or other sources. The extent of the public
market therefor and the availability of such quotations would depend, however,
upon such factors as the number of stockholders and/or the aggregate market
value of such securities remaining at such time, the interest in maintaining a
market in the Shares on the part of securities firms, the possible termination
of registration under the Exchange Act as described below, and other factors.
Purchaser cannot predict whether the reduction in the number of Shares that
might otherwise trade publicly would have an adverse or beneficial effect on
the market price for or marketability of the Shares or whether it would cause
future market prices to be greater or less than the Merger Consideration.
 
  Margin Regulations. The Shares are currently "margin securities," as such
term is defined under the rules of the Board of Governors of the Federal
Reserve System (the "Federal Reserve Board"), which has the effect, among other
things, of allowing banks to extend credit on the collateral of such
securities. Depending upon factors similar to those described above regarding
listing and market quotations, following the Offer it is possible that the
Shares might no longer constitute "margin securities" for purposes of the
margin regulations of the Federal Reserve Board, in which event such Shares
might no longer be eligible as collateral for loans made by banks.
 
  Exchange Act Registration. The Shares are currently registered under the
Exchange Act. Registration of the Shares under the Exchange Act may be
terminated upon application of the Company to the Commission if the Shares are
neither listed on a national securities exchange nor held by 300 or more
holders of record. Termination of registration of the Shares under the Exchange
Act would, subject to Section 15(d) of the Exchange Act, substantially reduce
the information required to be furnished by the Company to its stockholders and
to the Commission and would make certain provisions of the Exchange Act no
longer applicable to the Company, such as the short-swing profit recovery
provisions of Section 16(b) of the Exchange Act, the requirement of furnishing
a proxy or information statement pursuant to Section 14(a) or (c) of the
Exchange Act in connection with stockholders' meetings and the related
requirement of furnishing an annual report to stockholders and the requirements
of Rule 13e-3 under the Exchange Act with respect to "going private"
transactions. Furthermore, the ability of "affiliates" of the Company and
persons holding "restricted securities" of the Company to dispose of such
securities pursuant to Rule 144 or 144A promulgated under the Securities Act of
1933, as amended, may be impaired or eliminated.
 
  THE PURCHASER INTENDS TO SEEK TO CAUSE THE COMPANY TO APPLY FOR DELISTING OF
THE SHARES FROM THE NYSE AND TERMINATION OF REGISTRATION OF THE SHARES UNDER
THE EXCHANGE ACT AS SOON AFTER THE COMPLETION OF THE OFFER AS THE REQUIREMENTS
FOR SUCH DELISTING AND/OR TERMINATION ARE MET. IF REGISTRATION OF THE SHARES IS
NOT TERMINATED PRIOR TO THE MERGER, THEN THE REGISTRATION OF THE SHARES UNDER
THE EXCHANGE ACT WILL BE TERMINATED FOLLOWING THE CONSUMMATION OF THE MERGER.

  10. BACKGROUND OF THE OFFER; CONTACTS WITH THE COMPANY.
 
  In the spring of 1997, a group of dissident stockholders commenced but then
abandoned a proxy solicitation with the intention of replacing certain members
of the Company Board and adopting a proposal calling for the sale of the
Company. In the course of its discussions with stockholders regarding the
proxy contest, management became aware of the sentiment of certain of the
Company's stockholders that the Company be sold or combined with another auto
parts chain. Following discussions at a regularly scheduled meeting of the
Company Board on May 20, 1997, the Board concluded that entering into a
business combination with a complementary auto parts chain or selling the
Company would likely return value to the Company's stockholders sooner and
with more certainty than continuing the Company's strategy independently. The
Company selected and engaged SBC Warburg Dillon Read to assist and advise the
Company Board in seeking out a potential merger partner or acquiror of the
Company.
 
  During June and July of 1997, SBC Warburg Dillon Read contacted a number of
potential acquirors, including Parent. Parent indicated that it was not
interested in pursuing a transaction with the Company at that time. The
Company entered into confidentiality agreements and provided information to
some of these potential acquirors, including Discount Auto Parts, Inc.
("Discount"). The Company entered into negotiations with Discount beginning on
September 22, 1997 and on October 17, 1997, the Company and Discount entered
into a definitive merger agreement (the "Discount Merger Agreement").
 
  On October 29, 1997, Parent contacted Donaldson, Lufkin & Jenrette
Securities Corporation ("DLJ"), a financial advisor that has provided services
to Parent from time to time to discuss the potential benefits of an
acquisition of the Company by Parent. Shortly thereafter, DLJ contacted the
Company's financial advisor, SBC Warburg Dillon Read, to discuss the procedure
for Parent to pursue a transaction with the Company.
 
                                      15
<PAGE>
 
  During the week of November 3, Parent and DLJ conducted a preliminary
analysis, based on publicly available information, of a transaction between
Parent and the Company. Parent and DLJ had various teleconferences and
meetings during this period to review the benefits of a potential transaction
with the Company. On November 6, 1997, at a regularly scheduled meeting of the
Board of Directors of Parent (the "Parent Board"), senior management presented
the results of its preliminary analysis of the Company and the Parent Board
discussed the merits of a potential business combination with the Company.
Following these discussions, the Parent Board authorized senior management to
pursue a transaction with the Company. During the weeks of November 10 and
November 17, the Company and DLJ continued to review the merits of the
transaction.
 
  On November 25, 1997, Parent submitted a written proposal to the Company to
acquire all outstanding shares of the Company at a per Share price of $4.25,
subject to the satisfactory completion of its due diligence investigation and
reaching a definitive agreement. On November 26, 1997, representatives of the
Company indicated that the Company would be interested in pursuing further
discussions involving a potential transaction with Parent. The Company and
Parent entered into a confidentiality agreement on November 26, 1997 agreeing
to keep certain information provided by the Company confidential.
 
  Discussions between representatives of the Company and representatives of
Parent commenced on December 1, 1997 with respect to a potential acquisition
of the Company by Parent and certain information about the Company was
provided to Parent.
 
  During the weeks of December 1 and 8, 1997, various due diligence meetings
and conference calls were conducted between Parent, Company and their
respective advisors. During the week of December 8, 1997, such due diligence
activities included site visits to the Company's retail locations by
representatives of the Parent to conduct on-site reviews of the Company's
operations. Also during the week of December 8, 1997, representatives of the
Company and Parent and their advisors met to discuss the status of the due
diligence process and to continue the Parent's due diligence investigation.
 
  On December 16, 1997, counsel to Parent provided an initial draft of the
Merger Agreement to the Company and its counsel. Commencing December 17, 1997,
and continuing through December 22, 1997, extensive negotiations were
conducted with respect to the Merger Agreement, including an increase in the
Parent's original offer to $4.35 per Share, and revised drafts were exchanged.
 
  At a meeting of the Board of Directors of Parent commenced during the
morning of December 22, 1997 and reconvened during the afternoon of December
22, the Parent Board considered presentations from, and reviewed the terms and
conditions of the current draft of the Merger Agreement with, among others,
senior management of Parent, Parent's legal advisor and DLJ. DLJ made a
presentation to the Parent Board and delivered its opinion as to the fairness,
from a financial point of view, of the consideration to be paid in the Offer
to Parent. The Parent Board then unanimously approved and adopted the Merger
Agreement and approved the transactions contemplated thereby, subject to
termination by the Company of the Discount Merger Agreement pursuant to the
terms of the Discount Merger Agreement.
 
  Also, on the afternoon of December 22, 1997, the Company Board met to
consider the terms of the proposed transaction. SBC Warburg Dillon Read made a
presentation to the Company Board and delivered its opinion as to the
fairness, from a financial point of view, of the $4.35 cash consideration to
be paid in the Offer and the Merger to the Company and the holders of the
outstanding Shares. The Company Board then unanimously authorized the
termination of the Discount Merger Agreement after payment of the required
termination fee, approved and adopted the Merger Agreement and approved the
transactions contemplated thereby subject to termination of the Discount
Merger Agreement.
 
  The Discount Merger Agreement was terminated and a termination fee of $4.0
million was paid by the Company during the morning of December 23, 1997, and
immediately thereafter, Parent, Purchaser and the Company entered into the
Merger Agreement.
 
                                      16
<PAGE>
 
  The parties issued a press release announcing the transaction immediately
thereafter. A copy of the press release has been filed with the Commission as
an exhibit to the Schedule 14D-1 of Parent and the Purchaser (the "Schedule
14D-1"). On December 24, 1997, the Purchaser and Parent commenced the Offer.
 
  11. PURPOSE OF THE OFFER AND THE MERGER; PLANS FOR THE COMPANY.
 
  General. The purpose of the Offer is to acquire control of, and the entire
equity interest in, the Company. The purpose of the Merger is to acquire all
Shares not beneficially owned by the Purchaser following consummation of the
Offer. Upon the consummation of the Merger, the Company will become a wholly
owned subsidiary of Purchaser.
 
  The DGCL requires, among other things, that the adoption of any plan of
merger or consolidation of the Company must be approved by the Company Board
and generally by the holders of a majority of the Company's outstanding voting
securities. The Company Board has approved the Offer, the Merger and the Merger
Agreement and the transactions contemplated thereby; consequently, the only
additional action of the Company that may be necessary to effect the Merger is
approval by such stockholders if the "short-form" merger procedure described
below is not available.
 
  Plans for the Company. It is currently expected that, following consummation
of the Offer, initially the business and the operations of the Company will,
except as set forth in this Offer to Purchase, be continued by the Company, at
the discretion of the Company Board which will consist of a majority of
Parent's representatives, substantially as they are currently being conducted
with such changes as deemed appropriate by such Board. Parent will continue to
evaluate the business and operations of the Company during the pendency of the
Offer and after the consummation of the Offer and the Merger, and will take
such actions as its deems appropriate under the circumstances then existing.
Parent intends to seek additional information about the Company during this
period. Thereafter, Parent intends to review such information as part of a
comprehensive review of the Company's business, operations, capitalization and
management with a view to maximizing the Company's potential in conjunction
with Parent's businesses. It is expected that the business and operations of
the Company would form an important part of Parent's future business plans.
 
  Except as indicated in this Offer to Purchase, neither Parent nor Purchaser
has any present plans or proposals which relate to or would result in an
extraordinary corporate transaction, such as a merger, reorganization or
liquidation, involving the Company or any of its subsidiaries, a sale or
transfer of a material amount of assets of the Company or any of its
subsidiaries or any material change in the Company's capitalization or dividend
policy or any other material changes in the Company's corporate structure or
business, or the composition of the Company Board or management.
 
  Parent and the Purchaser reserve the right to acquire additional Shares
following the expiration of the Offer through private purchases, market
transactions, tender or exchange offers or otherwise on terms and at prices
that may be more or less favorable than those of the Offer or, subject to any
applicable legal restrictions, to dispose of any or all Shares beneficially
acquired by Parent and the Purchaser.
 
  The Merger. In general, under the DGCL and the Company's Certificate of
Incorporation, the Merger requires the approval of the Company Board and the
approval by the holders of a majority of all outstanding Shares.
 
  If the Purchaser acquires, through the Offer or otherwise, voting power with
respect to at least a majority of the outstanding Shares (which would be the
case if the Minimum Condition is satisfied and the Purchaser were to accept for
payment Shares tendered pursuant to the Offer), the Purchaser would have
sufficient voting power to effect the Merger without the vote of any other
stockholders.
 
  Further, the DGCL provides that if the parent corporation owns 90% or more of
each class of outstanding shares of a Delaware subsidiary, the Delaware
subsidiary may be the surviving corporation of a merger with its parent
corporation upon a majority vote of each corporation's entire board of
directors, without action or vote by
 
                                       17
<PAGE>
 
the stockholders of either corporation. Accordingly, if the Purchaser acquires
at least 90% or more of the outstanding Shares pursuant to the Offer or
otherwise, the Purchaser will be able to approve the Merger without a vote of
the Company's stockholders. In such event, the Purchaser has agreed that it
will take all necessary and appropriate action to cause the Merger to become
effective as soon as reasonably practicable after such acquisition. If
Purchaser does not acquire at least 90% of the outstanding Shares pursuant to
the Offer or otherwise, a significantly longer time may be required to effect
the Merger because a vote or the consent of the Company's stockholders would
be required under the DGCL.
 
  Appraisal Rights. No appraisal rights are available in connection with the
Offer. However, if the Merger is consummated, stockholders of the Company at
the time of the Merger will have certain rights under the DGCL to dissent and
demand appraisal of, and to receive payment in cash of the fair value of,
their Shares. Such rights to dissent, if the statutory procedures are complied
with, could lead to a judicial determination of the fair value of the Shares
(excluding any element of value arising from the accomplishment or expectation
of the Merger), required to be paid in cash to such dissenting holders for
their Shares. In addition, such dissenting stockholders would be entitled to
receive payment of a fair rate of interest from the date of consummation of
the Merger on the amount determined to be the fair value of their Shares. In
determining the fair value of the Shares, a Delaware court would be required
to take into account all relevant factors. Accordingly, such determination
could be based upon considerations other than, or in addition to, the market
value of the Shares, including among other things, asset values and earning
capacity of the Company. In Weinberger v. UOP, Inc., the Delaware Supreme
Court stated, among other things, 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 an appraisal
proceeding. Therefore, the value so determined in any appraisal proceeding
could be different from the price being paid in the Offer. The Delaware
Supreme Court stated in Weinberger and Rabkin v. Philip A. Hunt Chemical Corp.
that although the remedy ordinarily available to minority stockholders in a
cash-out merger is the right to appraisal described above, a damages remedy or
injunctive relief may be available if a merger is found to be the product of
procedural unfairness, including fraud, misrepresentation or other misconduct.
 
  Rule 13e-3. The Merger would have to comply with any applicable Federal law
operative at the time. Rule 13e-3 under the Exchange Act is applicable to
certain "going private" transactions. The Purchaser does not believe that Rule
13e-3 will be applicable to the Merger. Rule 13e-3 requires, among other
things, that certain financial information concerning the Company, and certain
information relating to the fairness of the proposed transaction and the
consideration offered to minority stockholders in such a transaction, be filed
with the Commission and disclosed to minority stockholders prior to
consummation of the transaction.
 
  12. THE MERGER AGREEMENT; CONFIDENTIALITY AGREEMENT.
 
  The Merger Agreement. The following is a summary of certain provisions of
the Merger Agreement. The summary is qualified in its entirety by reference to
the Merger Agreement, which is incorporated herein by reference. Capitalized
terms used but not defined herein shall have the meaning given to them in the
Merger Agreement.
 
  The Offer. The Merger Agreement provides that the Purchaser will commence
the Offer and that, upon the terms and subject to prior satisfaction or waiver
of the conditions of the Offer, the Purchaser will purchase all Shares validly
tendered and not properly withdrawn pursuant to the Offer. The Offer is
conditioned upon, among other things, there being tendered and not withdrawn
prior to the Expiration Date, a number of Shares which, together with any
Shares beneficially owned by Parent and Purchaser, represent a majority of the
outstanding Shares on a Fully Diluted Basis. The Merger Agreement provides
that, without the written consent of the Company, the Purchaser will not
decrease the Offer Price, change the form of consideration to be paid in the
Offer, reduce the maximum number of Shares to be purchased in the Offer or the
Minimum Condition, impose additional conditions to the Offer or amend any
condition of the Offer in a manner adverse to the holders of Shares. In the
event that all conditions of the Offer have not been satisfied or waived by
the Expiration Date, January 26, 1998, the Purchaser is required, at the
request of the Company, to extend the Offer from time to
 
                                      18
<PAGE>
 
time until 90 days after the commencement of the Offer. Additionally, the
Merger Agreement provides that notwithstanding that all conditions are
satisfied or waived prior to the scheduled Expiration Date, the Purchaser may
extend the Offer, subject to certain conditions, (i) for a period not to exceed
10 business days if the Shares tendered pursuant to the Offer are less than 90%
of the outstanding Shares and (ii) for a period not to exceed five business
days if an Adverse Market Change shall have occurred and be continuing on the
scheduled Expiration Date. The Purchaser will, on the terms and subject to the
prior satisfaction or waiver of the conditions of the Offer, accept for payment
and pay for Shares validly tendered and not properly withdrawn as soon as
practicable after expiration of the Offer.
 
  As used in the Merger Agreement, the following terms shall have the meanings
set forth below:
 
  "Adverse Market Change" means (i) any general suspension of trading in, or
limitation on prices for, securities on the NYSE or the Nasdaq National Market,
(ii) a declaration of a banking moratorium or any suspension of payments in
respect of banks in the United States (whether or not mandatory), (iii) a
commencement or escalation of a war, armed hostilities or other international
or national calamity directly involving the United States and having an adverse
effect on the financial markets in the United States, (iv) any material
limitation (whether or not mandatory) by any governmental authority, agency or
commission on the extension of credit by banks or other lending institutions in
the United States, and (v) in the case of any of the foregoing existing at the
time of the commencement of the Offer, a material acceleration or worsening
thereof; and
 
  "Fully Diluted Basis" means as of any time, all of the Shares plus all shares
of the Common Stock issuable upon exercise of outstanding options to acquire
the Common Stock minus 587,566 shares of Common Stock issuable upon exercise of
options which the holders thereof have irrevocably agreed in writing, in a form
satisfactory to Parent, not to exercise.
 
  The Merger. Following the consummation of the Offer, the Merger Agreement
provides that, subject to the terms and conditions thereof, and in accordance
with Delaware law, as soon as practicable, the Purchaser will be merged with
and into the Company. As a result of the Merger, the separate corporate
existence of the Purchaser will cease and the Company will continue as the
Surviving Corporation.
 
  The respective obligations of Parent and the Purchaser, on the one hand, and
the Company, on the other hand, to effect the Merger are subject to the
satisfaction on or prior to the Closing Date (as defined in the Merger
Agreement) of each of the following conditions: (i) the Merger Agreement shall
have been approved and adopted by the requisite vote of the holders of Shares,
if required by applicable law, in order to consummate the Merger; (ii) no
statute, rule, regulation, executive order, decree, ruling or injunction shall
have been enacted, entered, promulgated or enforced by any court or other
tribunal or governmental body or authority which prohibits the consummation of
the transactions contemplated therein substantially on the terms contemplated
thereby; (iii) any waiting periods applicable to the consummation of the Merger
under the HSR Act shall have expired or been terminated; and (iv) Purchaser
shall have purchased Shares pursuant to the Offer.
 
  At the Effective Time of the Merger (i) each issued and outstanding Share
(other than Dissenting Shares and Shares that are owned by the Company or any
wholly owned subsidiary of the Company, any Shares owned by Parent or any
wholly owned subsidiary of Parent, or any Shares which are held by stockholders
exercising dissenters' rights, if any, under Delaware law) will be converted
into the right to receive the Merger Consideration, and (ii) each issued and
outstanding share of capital stock of the Purchaser will be converted into one
share of common stock of the Surviving Corporation.
 
  The Company Board. The Merger Agreement provides that upon the purchase and
payment by Parent or the Purchaser of Shares representing at least a majority
of the outstanding Shares on a fully diluted basis, Parent shall be entitled to
designate such number of directors (rounded up to the next whole number) on the
Company Board so that the percentage of Parent's nominees on the Company Board
equals the percentage of outstanding Shares beneficially owned by Parent and
its affiliates. The Company shall, at such time, upon the request of
 
                                       19
<PAGE>
 
Purchaser promptly use its best efforts to take all action necessary to cause
such persons designated by Parent to be elected to the Company Board, if
necessary by increasing the size of the Company Board or securing resignations
of incumbent directors or both. At such time, the Company shall also cause
persons designated by Parent to constitute at least the same percentage
(rounded up to the next whole number) as is on the Company Board of (i) each
committee of the Company Board, (ii) each board of directors (or similar body)
of each subsidiary of the Company and (iii) each committee (or similar body)
of each such subsidiary board of directors.
 
  The Merger Agreement further provides that, notwithstanding the provisions
of the foregoing paragraph, until the Effective Time of the Merger, the
Company Board shall include at least two directors who were directors on the
date of the Merger Agreement (the "Independent Directors"). From and after the
time, if any, that Parent's designees constitute a majority of the Company
Board, the affirmative vote of a majority of Independent Directors shall be
required and shall be sufficient to authorize any termination of the Merger
Agreement by the Company, any amendment of the Merger Agreement requiring
action by the Company Board, any extension of time for the performance of any
of the obligations or other acts of Parent or Purchaser under the Merger
Agreement, any waiver of compliance with any of the agreements or conditions
under the Merger Agreement for the benefit of the Company, any action to seek
to enforce any obligation of Parent or Purchaser under the Merger Agreement
and any other action by the Company Board under or in connection with the
Merger Agreement. The Independent Directors shall be appointed as a Special
Committee of the Company Board and have full power and authority solely with
respect to the matters set forth in the previous sentence.
 
  Stockholders' Meeting. Pursuant to the Merger Agreement, the Company will,
if required by applicable law in order to consummate the Merger: (i) duly
call, give notice of, convene and hold a special meeting of its stockholders
(the "Special Meeting") as soon as practicable following the purchase of
Shares by the Purchaser pursuant to the Offer for the purpose of considering
and taking action upon the Merger and the adoption of the Merger Agreement;
(ii) prepare and file with the Commission a preliminary proxy or information
statement relating to the Merger and the Merger Agreement and include in any
preliminary or definitive proxy statement or information statement with
respect to the Special Meeting (the "Proxy Statement"), the recommendation of
the Company Board that stockholders of the Company vote in favor of the
approval of the Merger Agreement and the transactions contemplated thereby
unless the Company Board determines in good faith, based on advice of its
outside counsel, that not taking any such action is necessary in order for the
Company Board to comply with its obligations or duties to the Company and its
stockholders under applicable law; and (iii) use all reasonable efforts (A) to
obtain and furnish the information required to be included by it in the Proxy
Statement and, after consultation with the Parent and the Purchaser, respond
promptly to any comments made by the Commission with respect to the Proxy
Statement and any preliminary version thereof and cause the Proxy Statement to
be mailed to its stockholders at the earliest practicable time following the
expiration or termination of the Offer and (B) obtain the necessary approvals
by its stockholders of the Merger Agreement and the transactions contemplated
thereby unless the Company Board determines in good faith, based on advice of
its outside counsel, that not taking any such action is necessary in order for
the Company Board to comply with its obligations or duties to the Company and
its stockholders under applicable law. Purchaser and Parent have agreed to use
commercially reasonable efforts to cause the Special Meeting to occur within
90 days after the purchase of Shares pursuant to the Offer and Parent has
agreed that it will vote, or cause to be voted, all of the Shares then owned
by it, the Purchaser or any of its other subsidiaries and affiliates in favor
of the approval of the Merger and the adoption of the Merger Agreement. IF THE
PURCHASER ACQUIRES, THROUGH THE OFFER OR OTHERWISE, AT LEAST A MAJORITY OF THE
OUTSTANDING SHARES, THE PURCHASER WILL HAVE SUFFICIENT VOTING POWER TO APPROVE
THE MERGER, EVEN IF NO OTHER STOCKHOLDERS VOTE IN FAVOR OF THE MERGER.
 
  The Merger Agreement provides that in the event that Purchaser shall acquire
at least 90% of the then outstanding Shares, the parties agree to take all
necessary and appropriate action to cause the Merger to become effective, in
accordance with Section 253 of the DGCL, as soon as practicable after such
acquisition, without a meeting of the stockholders of the Company.
 
  Options. Each option granted to the Company's employees, consultants or
directors to acquire shares of Common Stock (each an "Option") that is
outstanding immediately prior to the purchase of Shares pursuant to
 
                                      20
<PAGE>
 
the Offer (irrespective of whether such Option is then exercisable) shall, on
the fifth business day after the purchase by Purchaser of Shares pursuant to
the Offer, be cancelled in exchange for a single lump sum cash payment equal to
the product of (i) the number of shares of Common Stock subject to such Option
and (ii) the excess of the Offer Price over the exercise price per share of
such Option. Subject to the previous sentence, each Option that is outstanding
immediately prior to the Effective Time, whether or not then vested or
exercisable, shall, effective as of the Effective Time, be cancelled and no
payments shall be made with respect thereto.
 
  Outstanding purchase rights under the Company's 1991 Associate Stock Purchase
Plan (the "Associate Purchase Plan") (i) shall be exercised at the next
scheduled date of exercise under the Associate Purchase Plan or (ii) shall be
terminated. No purchase rights shall be granted or exercised under the
Associate Purchase Plan, following such exercise date, and the Associate
Purchase Plan shall be terminated as soon as practicable thereafter.
 
  Interim Operations. Pursuant to the Merger Agreement, the Company has agreed
that, except as expressly contemplated by the Merger Agreement or agreed to in
writing by Parent, prior to the time the directors of the Parent constitute a
majority of the Company Board, the Company shall (a) cause, and cause each of
its subsidiaries to, conduct its operations in all material respects according
to their ordinary and usual course of business in substantially the same manner
as heretofore conducted; (b) use its reasonable best efforts, and cause each of
its subsidiaries to use its reasonable best efforts, to preserve intact its
business organization in all material respects, keep available the services of
its executive officers and key employees as a group, subject to changes in the
ordinary course, and maintain satisfactory relationships with suppliers,
distributors, customers and others having business relationships with them; (c)
confer at such times as Parent may reasonably request with one or more
representatives of Parent to report material operational matters and the
general status of ongoing operations (in each case to the extent Parent
reasonably requires such information) and to consult with Parent regarding
material operational decisions; (d) promptly notify Parent of any emergency or
other change in the normal course of its or its subsidiaries' respective
businesses or in the operation of its or its subsidiaries' respective
properties and of any complaints, investigations or hearings (or communications
indicating that the same may be contemplated) of any governmental body or
authority if such emergency, change, complaint, investigation or hearing is
reasonably likely to have a Material Adverse Effect on the Company; (e) not
authorize or pay any dividends on or make any distribution with respect to its
outstanding shares of stock; (f) not, and shall not permit any of its
subsidiaries to, except as otherwise contemplated by the Merger Agreement or as
may be required by applicable law, enter into or amend any employment,
severance or similar agreements or arrangements with any of their respective
directors or executive officers; (g) not, and shall not permit any of its
subsidiaries to, subject to the provisions described below under the heading

disposition of a material amount of assets or securities or any release or

ordinary course of business; (h) not propose or adopt any amendments to its
corporate charter or by-laws, except pursuant to the Merger as provided in the

subsidiaries to, grant, confer or award any options, warrants, conversion
rights or other rights, not existing on the date of the Merger Agreement, to

its subsidiaries to, purchase or redeem or offer to purchase or redeem any
shares of its stock or any securities convertible into or exchangeable for
shares of stock, except for the deemed repurchase of options in accordance with
the terms of the Merger Agreement, or purchases, redemptions and offers to
purchase in the ordinary course of business in connection with employee
incentive and benefit plans, programs or arrangements in existence on the date
of the Merger Agreement; (l) not, and shall not permit any of its subsidiaries
to, except as contemplated by the Merger Agreement or as may be required by
applicable law, amend in any material respect the terms of their respective
employee benefit plans, programs or arrangements or any severance or similar
agreements or arrangements in existence on the date of the Merger Agreement,
enter into or amend any employment or consulting agreement, adopt or enter into
any new employee benefit plans, programs or arrangements or any severance or
similar

agreements or arrangements or increase the base salary of any person who is a
party to a Change of Control Employment Agreement or make any payments under
any benefit plan to any director, employee, independent contractor or
consultant (except in the ordinary course of business and in amounts and in a
manner consistent with past practice or as otherwise required by law or the
provisions of such benefit plan); (m) not, and shall not permit any of its
subsidiaries to, (i) enter into any material loan agreement or incur any

not permit any of its subsidiaries to, make or change any material Tax

the Merger Agreement, not take any action which could reasonably be expected
to adversely affect or delay the ability of any of the parties to obtain any
approval of any governmental or regulatory body required to consummate the
transactions contemplated hereby; (s) not, and shall not permit any of its

recruiting activity and process employed by the Company and its subsidiaries
over the past twelve months; (aa) not, and shall not permit any of its

made as of a specified date) untrue and incorrect in any material respect as
of the Effective Time; (bb) not pay, discharge or satisfy any claim, liability
or obligation (absolute, accrued, asserted or unasserted, contingent or
otherwise), other than the payment, discharge or satisfaction, in the ordinary
course of business and consistent with past practice, of liabilities reflected
or reserved against in the September 30, 1997 balance sheet or subsequently
incurred in the ordinary course of business and consistent with past practice;
or (cc) not settle or compromise any pending or threatened suit, action or
claim not covered by insurance (without giving effect to deductibles in
determining whether coverage exists) that is material or which relates to the
Merger Agreement and the transactions contemplated thereby, including the
Offer and the Merger; or (dd) not modify, amend or waive any terms or
provisions of the Rights Agreement.
 
  No Solicitation. Pursuant to the Merger Agreement, the Company shall not,
and shall not authorize or permit, any of its officers, directors, employees,
attorneys, financial advisors, agents or other representatives or those of any
of its subsidiaries to, directly or indirectly, (a) solicit, initiate or
knowingly encourage any Takeover Proposal (as hereinafter defined), including
without limitation by disclosure of non-public information, or (b) engage in
discussions or negotiations relating to or accept any Takeover Proposal;
provided, however, that nothing shall prohibit the Company and its Board from
(i) taking and disclosing a position with respect to a
 
                                      22
<PAGE>
 
tender offer by a third party pursuant to Rules 14d-9 and 14e-2(a) promulgated
by the Commission under the Exchange Act, or (ii) at any time prior to the
purchase of Shares pursuant to the Offer, engaging in discussions or
negotiations with, and furnishing information (including non-public
information) concerning the Company and its subsidiaries, businesses,
properties or assets to, any third party which makes a Takeover Proposal
(without any solicitation or initiation or knowing encouragement, directly or
indirectly, by the Company or any of its representatives after the date of the
Merger Agreement) if the Company Board determines in good faith, based on
advice of its outside counsel (who may be its regularly engaged outside
counsel), that the failure to take such action will violate its obligations or
duties to the Company and its stockholders under applicable law, or (iii)
provided the Merger Agreement is terminated as described below in clause (iv)
under the heading "--Termination; Fees," accepting a Superior Proposal (as
hereinafter defined). Prior to furnishing information to or entering into
discussions or negotiations with any person, the Company shall receive from
such person or entity an executed confidentiality agreement in reasonably
customary form on terms not in the aggregate materially more favorable to such
person or entity than the terms contained in the Confidentiality Agreement (as
defined below) unless the same terms are granted to Parent. The Company shall
immediately cease and cause to be terminated any existing solicitation,
initiation, encouragement, activity, discussion or negotiation with any person
conducted heretofore by the Company or any of its representatives with respect
to any Takeover Proposal existing on the date hereof. The Company agrees not
to release any third party from, or waive any provision of, any standstill
agreement to which it is a party or any confidentiality agreement between it
and another person who has made, or who may reasonably be considered likely to
make, or who was given access in order to consider making, a Takeover
Proposal, unless the Company Board determines in good faith, based on advice
of its outside counsel (who may be its regularly engaged outside counsel),
that failure to take such action will violate its obligations or duties to the
Company and its stockholders under applicable law. The Company shall notify
Parent orally and in writing of any such Takeover Proposal received
(including, without limitation, the terms and conditions of any such proposal
and the identity of the person making it), within 24 hours of the receipt
thereof, and shall keep Parent informed of the general status and any material
changes in the terms and conditions of such Takeover Proposal. The Company
agrees to promptly provide to Parent any information concerning the Company,
its subsidiaries, business, properties or assets furnished to any third party
which makes a Takeover Proposal and which has not previously been provided to
Parent. As used in this Agreement, (i) "Takeover Proposal" shall mean any
written proposal or offer, in each case made prior to the stockholder vote at
the Special Meeting, other than a proposal or offer by Parent or any of its
subsidiaries, for a tender offer, recapitalization, merger, consolidation or
other business combination involving, or any purchase of, all or substantially
all of the assets or more than 50% of the voting securities of, the Company,
and (ii) "Superior Proposal" shall mean a bona fide Takeover Proposal made by
a third party on terms that a majority of the members of the Company Board
determines in their good faith reasonable judgment is more favorable to the
Company and its stockholders than the transactions contemplated by the Merger
Agreement.
 
  Termination; Fees. The Merger Agreement may be terminated and the Merger
abandoned at any time prior to the Effective Time, whether before or after
approval of the stockholders of the Company, (i) by mutual written consent of
Parent and the Company; (ii) by (a) either the Company or Parent if Shares
have not been purchased pursuant to the Offer on or before June 30, 1998 and
(b) the Company if after 90 days following the commencement of the Offer the
conditions to the Offer have not been satisfied or waived and the Purchaser
shall not have elected to extend the Offer; provided, that such right to
terminate pursuant to clause (i) or (ii) will not be available to any party
whose failure in any material respect to fulfill its obligation under the
Merger Agreement proximately contribute to, or resulted in, the failure of
Parent or the Purchaser to purchase the Shares pursuant to the Offer on or
before such date; (iii) by either the Company or Parent if (a) a statute,
rule, regulation or executive order shall have been enacted, entered or
promulgated prohibiting the purchase of Shares pursuant to the Offer or the
consummation of the Merger substantially on the terms contemplated by the
Merger Agreement or (b) an order, decree, ruling or injunction shall have been
entered permanently restraining, enjoining or otherwise prohibiting the
purchase of Shares pursuant to the Offer or the consummation of the Merger
substantially on the terms contemplated by the Merger Agreement and such
order, decree, ruling or injunction shall have become final and non-
appealable; provided, that the party seeking to terminate the Merger Agreement
shall have used its reasonable best efforts to remove such injunction, order
or decree; (iv) by the Company prior
 
                                      23
<PAGE>
 
to the purchase of Shares pursuant to the Offer if the Company Board
determines in good faith based upon advice of its outside counsel (a) that a
Takeover Proposal constitutes a Superior Proposal and (b) that failure to
accept such Superior Proposal will violate its obligations or duties to the
Company and the Company's stockholders under applicable law, provided, that
the Merger Agreement shall not terminate unless (Y) the Company has provided
Parent with two business days' prior written notice of its intention to accept
such Superior Proposal, together with a detailed description of the terms and
conditions of such Superior Proposal and (Z) simultaneously with such
termination the Company enters into a definitive acquisition, merger or
similar agreement to effect such Superior Proposal and pays the Termination
Fee (as defined below); (v) by either the Company or Parent prior to the
purchase of any Shares pursuant to the Offer if the other party shall have
breached, or failed to comply with, in any material respect any of its
obligations under the Merger Agreement or any representation or warranty made
by such other party shall have been untrue when made or as of the time of such
termination as if made on and as of such time (except for representations and
warranties made as of a specified date, which need be true only as of the
specified date), provided such breach, failure or misrepresentation is not
cured within thirty days after notice thereof from the other party and with
respect to any representation or warranty not qualified by "Material Adverse
Effect," such breaches, failures or misrepresentations individually or in the
aggregate, result or are reasonably likely to result in a Material Adverse
Effect on the Company or Parent, as the case may be; (vi) by Parent if the
Company Board or any committee of the Company Board, (a) shall withdraw,
modify or change in any adverse manner (including by amendment of the Schedule
14D-9) its approval or recommendation of the Merger Agreement, the Offer or
the Merger, (b) shall approve or recommend any Takeover Proposal, other than
by Parent or an affiliate of Parent, or (c) shall resolve to take any of the
actions specified in clause (a) or (b) above; (vii) by the Company if
Purchaser fails to commence the Offer on or prior to five business days
following the date of initial public announcement of the Offer, provided that
the Company may not terminate the Merger Agreement pursuant to this provision
if the Company is at such time in breach in any material respect of its
obligations under the Merger Agreement; or (viii) by either of the Company or
Parent if the Offer shall have been terminated, or the Offer has expired
without any Shares being purchased therein; provided, however, that the right
to terminate the Merger Agreement pursuant to this provision shall not be
available to any party whose failure to fulfill any obligation under the
Merger Agreement has been the cause of, or resulted in, the termination of the
Offer or the failure of Parent or Purchaser, as the case may be, to purchase
Shares pursuant to the Offer on or prior to such date. Notwithstanding the
foregoing, no termination by the Company shall be effective pursuant to clause
(vii) above under circumstances in which a Termination Fee would be payable by
the Company unless concurrently with such termination, such Termination Fee is
paid in full by the Company in accordance with the provisions of the Merger
Agreement.
 
  In the event that (i) prior to the termination of the Merger Agreement any
person shall have commenced, publicly proposed or communicated to the Company
a Takeover Proposal and (a) the Offer shall have remained open for at least 20
business days, (b) the Minimum Condition shall not have been satisfied, (c)
the Merger Agreement shall have been terminated pursuant to the provisions
described in clause (ii), (iii), (v) or (vii) of the preceding paragraph and
(d) prior to the first anniversary of such termination, the Company shall
consummate such Takeover Proposal; or (ii) if the Merger Agreement is
terminated by the Company or Parent pursuant to clauses (iv) and (vi) of the
preceding paragraph then in such event the Company shall pay Parent a
termination fee of $4.75 million (the "Termination Fee"), which amount shall
be paid by wire transfer of immediately available funds to an account
designated by Parent.
 
  Indemnification. Pursuant to the Merger Agreement, for six years after the
Effective Time, the Parent and the Surviving Corporation (or any successor to
the Surviving Corporation) will indemnify the present and former officers and
directors of the Company and its subsidiaries with respect to matters
occurring at or prior to the Effective Time to the full extent permitted under
Delaware law, the terms of the Company's charter, by-laws and indemnification
agreements, each as in effect as of the date of the Merger Agreement. For six
years from the Effective Time, Parent shall maintain in effect the Company's
directors' and officers' liability insurance policies and shall purchase such
policy at or prior to the Closing Date.
 
  Representations and Warranties. Pursuant to the Merger Agreement, the
Company has made customary representations and warranties to Parent and the
Purchaser with respect to, among other things, its organization,
 
                                      24
<PAGE>
 
capitalization, authority, financial statements, need for consents or
approvals, public filings, conduct of business, employee benefit plans,
intellectual property, employment matters, compliance with laws, tax matters,
insurance, litigation, title to properties, environmental matters, vote
required to approve the Merger Agreement, undisclosed liabilities, information
to be contained in the Proxy Statement, the opinion of its financial advisor
and significant vendor arrangements.
 
  Pursuant to the Merger Agreement, Parent and the Purchaser have made
substantially similar representations and warranties as to their organization,
authority, need for consents or approvals and information to be contained in
the Proxy Statement.
 
  Confidentiality Agreement. Pursuant to the Confidentiality Agreement entered
into on November 26, 1997 by Parent and the Company (the "Confidentiality
Agreement"), the Company and Parent agreed to provide, among other things, for
the confidential treatment of their discussions regarding the Offer and the
Merger and the exchange of certain confidential information concerning the
Company. The Confidentiality Agreement is incorporated herein by reference and
a copy of it has been filed with the Commission as an exhibit to the Schedule
14D-1. Parent further agreed that, for a period of 12 months from the date of
the Confidentiality Agreement, neither Parent nor any of its affiliates will
knowingly, as a result of knowledge or information obtained from the Evaluation
Material (as defined therein) or otherwise in connection with a possible
transaction: (i) divert or attempt to divert any business or customer of the
Company or any of its affiliates; nor (ii) employ or attempt to employ or
divert a managerial, professional or executive employee of the Company or any
of its affiliates.
 
  13. SOURCE AND AMOUNT OF FUNDS.
 
  The total amount of funds required to purchase all Shares validly tendered
pursuant to the Offer, consummate the Merger, repay outstanding indebtedness
and pay the costs and expenses related to the Offer and the Merger is estimated
to be approximately $100 million. Parent and Purchaser intend to obtain all
funds required in connection with the Offer and the Merger from borrowings
under a new $175 million Credit Facility (the "Facilities").
 
  The Parent has entered into a commitment letter (the "Commitment Letter") for
the Facilities with NationsBank, N.A. ("NationsBank") and NationsBanc
Montgomery Securities, Inc. ("NMSI"). NationsBank has committed to provide the
Facilities upon the terms and subject to the conditions set forth in the
Commitment Letter, and NMSI has committed to form a syndicate of financial
institutions reasonably acceptable to Parent (the "Lenders") for the
Facilities, upon the terms and subject to the conditions of the Commitment
Letter.
 
  Pursuant to the Commitment Letter, the Facilities are expected to consist of
an aggregate principal amount of up to $175 million as follows: (i) a $125
million revolving credit facility available to Parent (the "Revolving Credit
Facility") and (ii) a $50 million term loan tender facility (the "Tender
Facility") available to Purchaser and Parent.
 
  The following is a summary of the principal terms of the Facilities based
upon the Commitment Letter. This summary is qualified in its entirety by
reference to the Commitment Letter, a copy of which has been filed as an
exhibit to the Schedule 14D-1 filed by Parent with the Commission in connection
with the Offer.
 
  The Commitment Letter provides that the commitments of NationsBank and NMSI
will terminate unless the Facilities are closed on or prior to March 31, 1998.
 
  The Revolving Credit Facility will mature five years from closing of the
Offer and the Tender Facility will be subject to quarterly amortization, in
amounts to be determined, over a five year period following the closing of the
Offer. In addition, the Facilities will be subject to certain mandatory
prepayments and commitment reductions tied to the sale of assets and the
issuance of permitted debt.
 
                                       25
<PAGE>
 
  The amounts borrowed pursuant to the Revolving Credit Facility and the
Tender Facility will bear interest at a rate equal to, at Purchaser's option,
(i) LIBOR plus the Applicable Margin or (ii) the Alternate Base Rate (defined
as the higher of (a) the NationsBank prime rate and (b) the Federal Funds Rate
plus 0.50%) plus the Applicable Margin. The "Applicable Margin" will be set
forth in a schedule to the Facilities to be determined by reference to a ratio
of Parent's total funded debt to EBITDA.
 
  The Facilities will contain certain representations and warranties, certain
negative and affirmative financial covenants, certain conditions and events of
default which are customarily required for similar financings. Such covenants
will include restrictions and limitations on dividends and stock redemptions
and the redemption and/or prepayment of other debt, capital expenditures,
leases, incurrence of debt, liens, investments, transactions with affiliates,
acquisitions, mergers, consolidations and asset sales. Furthermore, Parent
will be required to maintain compliance with certain financial covenants such
as minimum tangible net worth, a maximum leverage ratio, a minimum fixed
charge coverage ratio, a current ratio and a limitation on capital
expenditures. The Facilities will not require the granting of any security by
Parent.
 
  The funding of the Facilities will be subject to customary closing
conditions, including, among other things, the execution of satisfactory
documentation, the receipt of all necessary governmental approvals, no
material adverse change in the business or financial condition of Parent or
the Company and completion of the Merger within 120 days after the Offer.
Although Parent expects that the Facilities will be available to provide funds
for the consummation of the Offer and the Merger in accordance with their
respective terms, there can be no assurance that the Facilities will be
consummated.
 
  Parent and Purchaser have agreed to pay certain fees to NationsBank and NMSI
for their own account and for the account of the Lenders including: (i) an
underwriting fee of 0.55% of the entire amount of the Facilities payable upon
the closing of the Facilities and (ii) a fee equal to the lesser of 15% of any
Termination Fee received by Parent pursuant to the Merger Agreement or
$500,000, in the event that the acquisition is not consummated.
 
  Parent will pay an annual administrative fee of $35,000 to NationsBank for
its own account as Agent for the Lenders under the Facilities, annually in
advance on the date of closing of the Facilities and on each anniversary date
thereafter, until the Facilities terminate.
 
  Purchaser anticipates that indebtedness incurred through borrowings under
the Facilities in connection with the Offer and Merger will be repaid from a
variety of sources, which may include, but may not be limited to, funds
generated internally by Purchaser and its subsidiaries (including, following
the Merger, funds generated by the Surviving Corporation), bank financing, and
the public or private sale of debt or equity securities. No decision has been
made concerning the method Purchaser will employ to repay such indebtedness.
Such decision will be made based on Purchaser's review from time to time of
the advisability of particular actions, as well as on prevailing interest
rates and financial and other economic conditions and such other factors as
Purchaser may deem appropriate.
 
  14. CERTAIN CONDITIONS OF THE OFFER.
 
  Notwithstanding any other provision of the Offer, and in addition to (and
not in limitation of) Purchaser's rights to extend the Offer under certain
circumstances (subject to the provisions of the Merger Agreement), Purchaser
shall not be required to accept for payment or, subject to the applicable
rules and regulations of the Commission, pay for, and may delay the acceptance
for payment of or, subject to the applicable rules and regulations of the
Commission, payment for, any Shares tendered pursuant to the Offer, and may
terminate the Offer and not accept for payment any Shares, if (x) any
applicable waiting period under the HSR Act has not expired or terminated
prior to the expiration of the Offer, (y) the Minimum Condition has not been
satisfied or (z) at any time on or after the date of the Merger Agreement and
before the time of acceptance of Shares pursuant to the Offer, any of the
following events shall have occurred:
 
    (a) there shall be any statute, rule, regulation, judgment, order or

  governmental authority, agency or commission ("Governmental Entity"), to
  the Offer or the Merger, that (i) prohibits or imposes any material
  limitations on Parent's or Purchaser's ownership or operation (or that of
  any of their respective subsidiaries or affiliates) of all or a portion of
  their or the Company's businesses or assets, or to compel Parent or
  Purchaser or their respective subsidiaries and affiliates to dispose of or
  hold separate any portion of the business or assets of the Company or
  Parent and their respective subsidiaries, which prohibition, limitation,
  disposition or hold separate obligation could reasonably be expected to
  have a Material Adverse Effect on Parent, (ii) restrains or prohibits the
  making or consummation of the Offer or the Merger or the performance of any
  of the other transactions contemplated by the Merger Agreement, (iii)
  imposes material limitations on the ability of Purchaser, or render
  Purchaser unable, to accept for payment, pay for or purchase some or all of
  the Shares pursuant to the Offer and the Merger, or (iv) imposes material
  limitations on the ability of Purchaser or Parent effectively to exercise
  full rights of ownership of the Shares, including, without limitation, the
  right to vote the Shares purchased by it on all matters properly presented
  to the Company's stockholders; or
 
    (b) (i) the Company Board (or any committee thereof) shall have
  withdrawn, modified or changed in any adverse manner to Parent and
  Purchaser its approval or recommendation of the Offer or the Merger or the
  Merger Agreement, or shall have endorsed, approved or recommended any other
  Takeover Proposal or (ii) the Company shall have entered into any agreement
  with respect to any Superior Proposal pursuant to the provision described
  in clause (iv) under the heading "Termination Fees" in Section 12 hereof or
 
    (c) the representations and warranties of the Company set forth in the
  Merger Agreement shall not be true and correct, in each case (i) as of the
  date referred to in any representation or warranty which addresses matters
  as of a particular date, or (ii) as to all other representations and
  warranties, as of the date of the Merger Agreement and as of the scheduled
  expiration of the Offer, and with respect to any representations and
  warranties not qualified by "Material Adverse Effect," unless the
  inaccuracies under such representation and warranties, taking all the
  inaccuracies under all such representations and warranties together in
  their entirety, do not, individually or in the aggregate, result in a
  Material Adverse Effect on the Company; or
 
    (d) the Company shall have failed to perform any obligation or to comply
  with any agreement or covenant to be performed or complied with by it under
  the Merger Agreement other than any failure which would not have, either
  individually or in the aggregate, a Material Adverse Effect on the Company;
  or
 
    (e) the Merger Agreement shall have been terminated by the Company or
  Parent or Purchaser in accordance with its terms or Parent or Purchaser
  shall have reached an agreement or understanding in writing with the
  Company providing for termination or amendment of the Offer or delay in
  payment for the Shares;
 
  which, in the reasonable judgment of Parent and Purchaser, in any such
  case, and regardless of the circumstances giving rise to any such
  conditions, makes it inadvisable to proceed with the Offer and/or with such
  acceptance for payment of or payment for Shares.
 
  The foregoing conditions (other than the Minimum Condition) are for the sole
benefit of Parent and Purchaser and, subject to the Merger Agreement, may be
asserted by Parent or Purchaser regardless of the circumstances giving rise to
such condition or may be waived by Parent or Purchaser in whole or in part at
any time and from time to time in its sole discretion. The failure by Parent or
Purchaser at any time to exercise any of the foregoing rights shall not be
deemed a waiver of any such right and each such right shall be deemed an
ongoing right which may be asserted at any time and from time to time.
 
  15. CERTAIN LEGAL MATTERS.
 
  Except as described in this Section 15, based on information provided by the
Company, none of the Company, Purchaser or Parent is aware of any license or
regulatory permit that appears to be material to the business of the Company
and its subsidiaries, taken as a whole, that might be adversely affected by the
Purchaser's acquisition of Shares (and the indirect acquisition of the stock of
the Company's subsidiaries) as contemplated herein or of any approval or other
action by a domestic or foreign governmental, administrative or
 
                                       27
<PAGE>
 
regulatory agency or authority that would be required or desirable for the
acquisition and ownership of the Shares (and the indirect acquisition of the
stock of the Company's subsidiaries) by the Purchaser as contemplated herein.
Should any such approval or other action be required or desirable, the
Purchaser and Parent presently contemplate that such approval or other action
will be sought, except as described below under "State Takeover Laws." While,
except as otherwise described in this Offer to Purchase, the Purchaser does not
presently intend to delay the acceptance for payment of or payment for Shares
tendered pursuant to the Offer pending the outcome of any such matter, there
can be no assurance that any such approval or other action, if needed, would be
obtained, or would be obtained without substantial conditions, or that failure
to obtain any such approval or other action might not result in consequences
adverse to the Company's business or that certain parts of the Company's
business might not have to be disposed of or other substantial conditions
complied with in the event that such approvals were not obtained or such other
actions were not taken in order to obtain any such approval or other action. If
certain types of adverse action are taken with respect to the matters discussed
below, the Purchaser could decline to accept for payment or pay for any Shares
tendered. See Section 14 for certain conditions to the Offer, including
conditions with respect to governmental actions.
 
  (a) State Takeover Laws. The Company is incorporated under the laws of the
State of Delaware. In general, Section 203 of the DGCL prevents an "interested
stockholder" (e.g., a person who owns or has the right to acquire 15% or more
of a corporation's outstanding voting stock) from engaging in a "business
combination" (defined to include mergers and certain other transactions) with a
Delaware corporation for a period of three years following the time such person
became an interested stockholder unless, among other things, the corporation's
board of directors approves such business combination or the transaction in
which the interested stockholder becomes such prior to the time the interested
stockholder becomes such. The Board of Directors of the Company has approved
the Offer, the Merger and the Merger Agreement for the purposes of Section 203
of the DGCL. A number of other states have adopted laws and regulations
applicable to attempts to acquire securities of corporations which are
incorporated, or have substantial assets, stockholders, principal executive
offices or principal places of business, or whose business operations otherwise
have substantial economic effects in such states. In Edgar v. MITE Corp., the
Supreme Court of the United States invalidated on constitutional grounds the
Illinois Business Takeover statute, which, as a matter of state securities law,
made takeovers of corporations meeting certain requirements more difficult.
However in 1987, in CTS Corp. v. Dynamics Corp. of America, the Supreme Court
held that the State of Indiana may, as a matter of corporate law and, in
particular, with respect to those aspects of corporate law concerning corporate
governance, constitutionally disqualify a potential acquiror from voting on the
affairs of a target corporation without the prior approval of the remaining
presenting stockholders. The state law before the Supreme Court was by its
terms applicable only to corporations that had a substantial number of
stockholders in the state and were incorporated there.
 
  Except as described above with respect to Section 203 of the DGCL, the
Purchaser has not attempted to comply with the takeover laws of any other
state. Should any person seek to apply any state takeover law, the Purchaser
will take such action as then appears desirable, which may include challenging
the validity or applicability of any such statute in appropriate court
proceedings. In the event it is asserted that one or more state takeover laws
is applicable to the Offer or the Merger, and an appropriate court does not
determine that it is inapplicable or invalid as applied to the Offer, the
Purchaser might be required to file certain information with, or receive
approvals from, the relevant state authorities. In addition, if enjoined, the
Purchaser might be unable to accept for payment any Shares tendered pursuant to
the Offer, or be delayed in continuing or consummating the Offer and the
Merger. In such case, the Purchaser may not be obligated to accept for payment
any Shares tendered. See Section 14.
 
  The Company and certain of its subsidiaries conduct business in a number of
other states throughout the United States, some of which have enacted takeover
laws and regulations. Neither Parent nor the Purchaser knows whether any or all
of these takeover laws and regulations will by their terms apply to the Offer,
and, except as set forth above, neither Parent nor the Purchaser has currently
complied with any other state takeover statute or regulation. The Purchaser
reserves the right to challenge the applicability or validity of any state law
purportedly applicable to the Offer and nothing in this Offer to Purchase or
any action taken in connection with
 
                                       28
<PAGE>
 
the Offer is intended as a waiver of such right. If it is asserted that any
state takeover statute is applicable to the Offer and an appropriate court does
not determine that it is inapplicable or invalid as applied to the Offer, the
Purchaser might be required to file certain information with, or to receive
approvals from, the relevant state authorities, and the Purchaser might be
unable to accept for payment or pay for Shares tendered pursuant to the Offer,
or may be delayed in consummating the Offer. In such case, the Purchaser may
not be obligated to accept for payment or pay for any Shares tendered pursuant
to the Offer. See Section 14.
 
  (b) Antitrust. The Offer and the Merger are subject to the HSR Act, which
provides that certain acquisition transactions may not be consummated unless
certain information has been furnished to the Antitrust Division of the
Department of Justice (the "Antitrust Division") and the Federal Trade
Commission (the "FTC") and certain waiting period requirements have been
satisfied.
 
  Parent and the Company expect to file their Notification and Report Forms
with respect to the Offer under the HSR Act in the near future. The waiting
period under the HSR Act with respect to the Offer will expire at 11:59 p.m.,
New York City time, on the 15th day after the date Parent's form is filed
unless early termination of the waiting period is granted. However, the
Antitrust Division or the FTC may extend the waiting period by requesting
additional information or documentary material from Parent or the Company. If
such a request is made, such waiting period will expire at 11:59 p.m., New York
City time, on the tenth day after substantial compliance by Parent with such
request. Only one extension of the waiting period pursuant to a request for
additional information is authorized by the HSR Act. Thereafter, such waiting
period may be extended only by court order or with the consent of Parent. In
practice, complying with a request for additional information or material can
take a significant amount of time. In addition, if the Antitrust Division or
the FTC raises substantive issues in connection with a proposed transaction,
the parties frequently engage in negotiations with the relevant governmental
agency concerning possible means of addressing those issues and may agree to
delay consummation of the transaction while such negotiations continue. The
Purchaser will not accept for payment Shares tendered pursuant to the Offer
unless and until the waiting period requirements imposed by the HSR Act with
respect to the Offer have been satisfied. See Section 14.
 
  As discussed below, the HSR Act requirements with respect to the Merger will
not apply if certain conditions are met. In particular, the Merger may not be
consummated until 30 calendar days after receipt by the Antitrust Division and
the FTC of the Notification and Report Forms of both Parent and the Company
unless the Purchaser acquires 50% or more of the outstanding Shares pursuant to
the Offer (which would be the case if the Minimum Condition were satisfied) or
the 30-day period is earlier terminated by the Antitrust Division and the FTC.
Within such 30-day period, the Antitrust Division or the FTC may request
additional information or documentary materials from Parent and/or the Company.
The Merger may not be consummated until 20 days after such requests are
substantially complied with by both Parent and the Company. Thereafter, the
waiting periods may be extended only by court order or with the consent of
Parent and the Company.
 
  The FTC and the Antitrust Division frequently scrutinize the legality under
the antitrust laws of transactions such as the Purchaser's acquisition of
Shares pursuant to the Offer and the Merger. At any time before or after the
Purchaser's acquisition of Shares, the Antitrust Division or the FTC could take
such action under the antitrust laws as it deems necessary or desirable in the
public interest, including seeking to enjoin the acquisition of Shares pursuant
to the Offer or otherwise or seeking divestiture of Shares acquired by the
Purchaser or divestiture of substantial assets of Parent or its subsidiaries.
Private parties, as well as state governments, may also bring legal action
under the antitrust laws under certain circumstances. Based upon an examination
of information provided by the Company relating to the businesses in which
Parent and the Company are engaged, Parent and the Purchaser believe that the
acquisition of Shares by the Purchaser will not violate the antitrust laws.
Nevertheless, there can be no assurance that a challenge to the Offer or other
acquisition of Shares by the Purchaser on antitrust grounds will not be made
or, if such a challenge is made, of the result. See Section 14 for certain
conditions to the Offer, including conditions with respect to injunctions and
certain governmental actions.
 
  (c) Federal Reserve Board Regulations. Regulations G, U and X (the "Margin
Regulations") of the Federal Reserve Board restrict the extension or
maintenance of credit for the purpose of buying or carrying margin stock,
 
                                       29
<PAGE>
 
including the Shares, if the credit is secured directly or indirectly by margin
stock. Such secured credit may not be extended or maintained in an amount that
exceeds the maximum loan value of all the direct and indirect collateral
securing the credit, including margin stock and other collateral.
 
  As described in Section 13 of this Offer to Purchase, the financing of the
Offer will not be directly or indirectly secured by the Shares or other
securities which constitute margin stock. Accordingly, all financing for the
Offer will be in full compliance with the Margin Regulations.
 
  Rights Plan. In August of 1996, the Company Board adopted a preferred stock
purchase rights plan pursuant to which holders of Common Stock were issued
rights (exercisable after certain triggering events) to purchase shares of a
series of preferred stock of the Company. The Rights Agreement was amended
October 17, 1997. On December 23, 1997, the Rights Agreement was further
amended to provide that the transactions contemplated by the Merger Agreement
will not trigger the provisions of the Rights Agreement.
 
  16. FEES AND EXPENSES.
 
  Except as set forth below, neither Parent nor the Purchaser will pay any fees
or commissions to any broker, dealer or other person for soliciting tenders of
Shares pursuant to the Offer.
 
  DLJ is acting as Dealer Manager in connection with the Offer and is acting as
financial advisor to Parent in connection with its effort to acquire the
Company. Parent has agreed to pay DLJ for its services an initial financial
advisory fee of $300,000, payable upon the earliest of (1) the commencement of
the Offer, (2) the execution of a definitive agreement with respect to an
acquisition of the Company by Parent, or (3) the time DLJ notifies the Board of
Parent that it is prepared to deliver its fairness opinion. Parent has agreed
to pay an additional fee of $50,000 for each update of a prior fairness opinion
delivered by DLJ with respect to the Offer and, upon request by DLJ from time
to time, to reimburse DLJ for all out-of-pocket expenses (including the
reasonable fees and expenses of counsel) incurred by DLJ in connection with its
engagement, which amount may not exceed $50,000 without the prior approval of
Parent. In addition, Parent has agreed to pay DLJ an amount equal to $1.25
million, less any amount paid pursuant to the preceding sentences, upon the
earliest of: (a) the acquisition by Parent or any of its affiliates of a
majority of the outstanding Shares calculated on a fully diluted basis; (b) a
merger or consolidation of the Company with Parent or an affiliate of Parent;
(c) the acquisition by Parent or any of its affiliates of assets of the Company
representing a majority of the Company's book value; or (d) in the consummation
of certain other transactions. Parent has also agreed to indemnify DLJ and
certain related persons against certain liabilities and expenses in connection
with its engagement, including certain liabilities under the federal securities
laws. DLJ has rendered various investment banking and other advisory services
to Parent and its affiliates in the past and is expected to continue to render
such services, for which it has received and will continue to receive customary
compensation from Parent and its affiliates.
 
  The Purchaser has retained Innisfree M&A Incorporated to act as the
Information Agent in connection with the Offer. The Information Agent may
contact holders of Shares by mail, telephone, facsimile, telegraph and personal
interviews and may request brokers, dealers and other nominee stockholders to
forward materials relating to the Offer to beneficial owners of Shares. The
Information Agent will receive reasonable and customary compensation for its
services, will be reimbursed for certain reasonable out-of-pocket expenses and
will be indemnified against certain liabilities and expenses in connection
therewith, including certain liabilities under the federal securities law.
 
  In addition, Chase Mellon Shareholder Services, L.L.C. has been retained as
the Depositary. The Depositary has not been retained to make solicitations or
recommendations in its role as Depositary. The Depositary will receive
reasonable and customary compensation for its services, will be reimbursed for
certain reasonable out-of-pocket expenses and will be indemnified against
certain liabilities and expenses in connection therewith, including certain
liabilities under the federal securities laws. Brokers, dealers, commercial
banks and trust companies will be reimbursed by the Purchaser for customary
mailing and handling expenses incurred by them in forwarding offering material
to their customers.

  17. MISCELLANEOUS.
 
  The Purchaser is not aware of any jurisdiction where the making of the Offer
is prohibited by any administrative or judicial action pursuant to any valid
state statute. If the Purchaser becomes aware of any valid
state statute prohibiting the making of the Offer or the acceptance of the
Shares pursuant thereto, Purchaser will make a good faith effort to comply with
such state statute. If, after such good faith effort, the Purchaser cannot
comply with any such state statute, the Offer will not be made to (nor will
tenders be accepted from or on behalf of) the holders of Shares in such state.
In any jurisdiction where the securities, blue sky or other laws require the
Offer to be made by a licensed broker or dealer, the Offer shall be deemed to
be made on behalf of the Purchaser by the Dealer Manager or one or more
registered brokers or dealers which are licensed under the laws of such
jurisdiction.
 
  NO PERSON HAS BEEN AUTHORIZED TO GIVE ANY INFORMATION OR MAKE ANY
REPRESENTATION ON BEHALF OF PARENT, THE PURCHASER OR THE COMPANY NOT CONTAINED
IN THIS OFFER TO PURCHASE OR IN THE LETTER OF TRANSMITTAL AND, IF GIVEN OR
MADE, SUCH INFORMATION OR REPRESENTATION MUST NOT BE RELIED UPON AS HAVING BEEN
AUTHORIZED. NEITHER THE DELIVERY OF THIS OFFER TO PURCHASE NOR ANY PURCHASE
PURSUANT TO THE OFFER, SHALL, UNDER ANY CIRCUMSTANCES, CREATE ANY IMPLICATION
THAT THERE HAS BEEN NO CHANGE IN THE AFFAIRS OF PARENT, THE PURCHASER OR THE
COMPANY SINCE THE DATE AS OF WHICH INFORMATION IS FURNISHED OR THE DATE OF THIS
OFFER TO PURCHASE.
 
  Parent and the Purchaser have filed with the Commission a Schedule 14D-1,
together with exhibits, pursuant to Rule 14d-3 of the General Rules and
Regulations under the Exchange Act, furnishing certain additional information
with respect to the Offer, and may file amendments thereto. In addition, the
Company has filed with the Commission a Solicitation/Recommendation Statement
on Schedule 14D-9 (including exhibits) pursuant to Rule 14d-9 under the
Exchange Act. Such statements and any amendments thereto, including exhibits,
may be inspected at, and copies may be obtained from, the same places and in
the same manner as set forth in Section 8 (except that they will not be
available at the regional offices of the Commission).

full voting and other rights with respect to such Shares, including voting at
any meeting of stockholders then scheduled.

ONLY WHEN ACTUALLY RECEIVED OF THE DEPOSITARY. IF SENT BY MAIL, REGISTERED
MAIL RETURN RECEIPT REQUIRED, PROPERLY INSURED, IS RECOMMENDED. IN ALL CASES,
SUFFICIENT TIME SHOULD BE ALLOWED TO ENSURE TIMELY DELIVERY.

fractions of Shares will be purchased. All tendering stockholders, by
execution of this Letter of Transmittal, waive any right to receive any notice
of the acceptance of their Shares for payment.
 
  3. INADEQUATE SPACE. If the space provided is inadequate, the certificate
numbers and number of Shares should be listed on a separate signed schedule
and attached hereto.
 
  4. PARTIAL TENDERS. If fewer than all of the Shares evidenced by any
certificate are to be tendered, fill in the number of Shares which are to be
tendered in the column entitled "Number of Shares Tendered." A new certificate
for the remainder of the Shares evidenced by your old certificate(s) will be
sent to you as soon as practicable after the Expiration Date. All Shares
represented by certificates delivered to the Depositary are deemed to have
been tendered unless otherwise indicated.

whatsoever.
 
  (b) If the Shares tendered are held of record by two or more joint holders,

<PAGE>
 
  (d) If this Letter of Transmittal is signed by the registered holder(s) of
the Shares tendered hereby, no endorsements of certificates or separate stock
powers are required. If, however, payment is to be made to, or the
certificates for Shares not tendered or accepted for payment are to be issued
to, a person other than the registered holder(s), then the certificates
transmitted hereby must be endorsed or accompanied by appropriate stock
powers, in either case signed exactly as the name(s) of the registered
holder(s) appears on the certificates. Signatures on such certificates or
stock powers must be guaranteed by an Eligible Institution.
 
  (e) If this Letter of Transmittal is signed by a person other than the
registered holder of the certificates tendered, the certificates must be
endorsed or accompanied by appropriate stock powers, in either case signed
exactly as the name(s) of the registered holder(s) appear on the certificates.
Signatures on such certificates or stock powers required by Instruction 1
above must be guaranteed by an Eligible Institution.
 
  (f) If this Letter of Transmittal or any certificates or stock powers are
signed by officers of corporations, trustees, executors, administrators,
guardians, attorneys-in-fact or others acting in a fiduciary representative
capacity, such persons should so indicate when signing, and must submit proper
evidence satisfactory to the Purchaser of their authority so to act.
 
  6. STOCK TRANSFER TAXES. Except as set forth in this Instruction 6, the
Purchaser will pay, or cause to be paid, any stock transfer taxes with respect
to the transfer and sale of Shares to it or its assignee pursuant to the
Offer. If, however, payment of the purchase price is to be made to, or if
certificates for Shares not tendered or accepted for payment are to be
registered in the name of, any persons other than the registered holder(s), or
if tendered certificates are registered in the name of any person other than
the person(s) signing this Letter of Transmittal, the amount of any stock
transfer taxes (whether imposed on the registered holder or such person)
payable on the account of the transfer to such person will be deducted from
the purchase price unless satisfactory evidence of the payment of such taxes
or exemption therefrom is submitted.
 
  Except as provided in this Instruction 6, it will not be necessary for
transfer tax stamps to be affixed to the certificates listed in this Letter of
Transmittal.
 
  7. SPECIAL PAYMENT AND DELIVERY INSTRUCTIONS. If a check for the purchase
price of any Shares tendered hereby is to be issued, or certificate(s)
representing Shares not tendered or not purchased are to be issued, in the
name of a person other than the person(s) signing this Letter of Transmittal
or if such check or any such certificate is to be sent to someone other than
the person(s) signing this Letter of Transmittal or to the person(s) signing
this Letter of Transmittal but at an address other than that shown in the box
entitled "Description of Shares Tendered", the appropriate boxes in this
Letter of Transmittal must be completed. Stockholders delivering Shares
tendered hereby by book entry transfer may request that Shares not purchased
be credited to such account maintained at a Book-Entry Transfer Facility as
such stockholder may designate in the box entitled "Special Payment
Instructions". If no such instructions are given, all such Shares not
purchased will be returned by crediting the account at the Book-Entry Transfer
Facility designated herein as the account from which such Shares were
delivered.
 
  8. IRREGULARITIES. All questions as to the validity, form, eligibility
(including timeliness of receipt) and acceptance for payment of any tender of
Shares will be determined by the Purchaser, in its sole discretion, which
determination shall be final and binding. The Purchaser reserves the absolute
right to reject any or all tenders of any Shares determined by it to be not in
appropriate form or the acceptance of or payment for which may, in the opinion
of the Purchaser's counsel, be unlawful. The Purchaser also reserves the
absolute right to waive any of the conditions of the Offer or any defect or
irregularity in any tender with respect to any particular Shares or any
particular stockholder, and the Purchaser's interpretations of the terms and
conditions of the Offer (including these instructions) shall be final and
binding on all parties. Unless waived, any defects or irregularities in
connection with tenders must be cured within such time as the Purchaser shall
determine. None of the Purchaser, the Depositary or the Information Agent or
any other person will be under duty to give notification of any defects or
irregularities in tenders, or incur any liability for failure to give such
notification. Tenders will not be deemed to have been validly made until all
defects and irregularities have been cured or waived.
 
  9. SUBSTITUTE FORM W-9. The tendering stockholder is required to provide the
Depositary with a correct Taxpayer Identification Number ("TIN") on Substitute
Form W-9. Failure to provide the information on the form may subject the
tendering stockholder to 31% federal income tax withholding on any amount
otherwise payable to the stockholder. The box in Part 2 of the form may be
checked if the tendering stockholder has not been issued a TIN and has applied
for a number or intends to apply for a number in the near future. If the box
in Part 2 is checked and the Depositary is not provided with a TIN within 60
days, the Depositary will withhold 31% on all payments of the purchase price
thereafter until a TIN is provided to the Depositary.
 
  10. REQUESTS FOR ASSISTANCE OR ADDITIONAL COPIES. Requests for assistance or
additional copies of the Offer to Purchase and this Letter of Transmittal may
be directed to the Information Agent at the address set forth or your broker,
dealer, commercial bank or trust company.
 
  11. LOST OR DESTROYED CERTIFICATES. If any certificate(s) representing
Shares has been lost or destroyed, the stockholder should check the
appropriate box on the front of the Letter of Transmittal. The Company's stock
transfer agent will then instruct such stockholder as to the procedure to be
followed in order to replace the certificate(s). The stockholder may have to
post a surety bond of approximately 2% of the current market value of the
stock. This Letter of Transmittal and related documents cannot be processed
until procedures for replacing lost or destroyed certificates have been
followed.

  IMPORTANT: THIS LETTER OF TRANSMITTAL (OR A FACSIMILE COPY THEREOF) TOGETHER
WITH CERTIFICATES OR A BOOK-ENTRY CONFIRMATION FOR SHARES AND ALL OTHER
REQUIRED DOCUMENTS OR THE NOTICE OF GUARANTEED DELIVERY (OR A FACSIMILE COPY
THEREOF) MUST BE RECEIVED BY THE DEPOSITARY, ON OR PRIOR TO THE EXPIRATION
DATE (AS DEFINED IN THE OFFER TO PURCHASE).
 
                           IMPORTANT TAX INFORMATION
 
  Under the federal income tax law, a stockholder whose tendered Shares are
accepted for payment is required by law to provide the Depositary (as payer)
with his correct taxpayer identification number on Substitute Form W-9. If
such a stockholder is an individual, the taxpayer identification number is his
Social Security number. For businesses and other entities, the taxpayer
identification number is its Employer Identification Number. If the Depositary
is not provided with the correct taxpayer identification number, the
stockholder may be subject to a $50 penalty imposed by the Internal Revenue
Service, and payments made to such stockholder with respect to Shares
purchased pursuant to the Offer may be subject to federal income tax backup
withholding. To prevent federal income tax backup withholding on payments made
to a stockholder with respect to Shares purchased pursuant to the Offer, each
stockholder is required to notify the Depositary with his correct taxpayer
identification number by completing the form certifying that the taxpayer
identification number provided on Substitute Form W-9 is correct (or that such
stockholder is awaiting a taxpayer identification number) and that (1) the
stockholder has not been notified by the Internal Revenue Service that he is
subject to federal income tax backup withholding as a result of failure to
report all interest or dividends or (2) the Internal Revenue Service has
notified the stockholder that he is no longer subject to federal income tax
backup withholding.
 
  Exempt stockholders (including, among others, all corporations and certain
foreign individuals) are not subject to these federal income tax backup
withholding and reporting requirements. In order for a foreign individual to
qualify as an exempt recipient, that stockholder must submit a statement,
signed under penalties of perjury, attesting to that individual's exempt
status. Such statements can be obtained from the Depositary. See the enclosed
Guidelines for Certification of Taxpayer Identification Number of Substitute
Form W-9 for additional instructions.
 
  If federal income tax backup withholding applies, the Depositary is required
to withhold 31% of the payments made to a stockholder. Backup withholding is
not an additional tax. Rather, the tax liability of person subject to federal
income tax backup withholding will be reduced by the amount of tax withheld.
If withholding results in an overpayment of taxes, a refund generally may be
obtained.
 
WHAT NUMBER TO GIVE THE DEPOSITARY
 
  The stockholder is required to give the Depositary the Social Security
number or Employer Identification Number of the registered holder of the
Shares. If the Shares are in more than one name or are not in the name of the
actual owner, consult the enclosed Guideline for Certification of Taxpayer
Identification Number on Substitute Form W-9 for additional guidance on which
number to report.
 
NOTE: FAILURE TO COMPLETE AND RETURN THE SUBSTITUTE FORM W-9 MAY RESULT IN
      BACKUP WITHHOLDING OF 31% OF ANY PAYMENTS MADE TO YOU PURSUANT TO THE
      OFFER. PLEASE REVIEW THE ENCLOSED GUIDELINES FOR CERTIFICATION OF
      TAXPAYER IDENTIFICATION UMBER ON SUBSTITUTE FORM W-9 FOR ADDITIONAL
      DETAILS.

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

SPRINGFIELD, MISSOURI and HOUSTON, TEXAS, December 23, 1997 - O'Reilly 
Automotive, Inc. (Nasdaq-ORLY) ("O'Reilly") and HI-LO Automotive, Inc. 
(NYSE-HLO) ("Hi/LO") today jointly announced that the two companies have signed 
a definitive merger agreement for the acquisition of Hi/LO by O'Reilly.

Under the terms of the agreement, a subsidiary of O'Reilly will commence a 
tender offer on December 24, 1997 to acquire all of the outstanding shares of 
Hi/LO for $4.35 per share in cash.  Following the completion of the tender 
offer, O'Reilly will consummate a second step merger in which remaining Hi/LO 
stockholders will also receive $4.35 per share in cash.

The acquisition will add 188 new stores in Texas, Louisiana and California, 
along with a 375,000 square foot distribution center in Houston, Texas to 
O'Reilly's current 259 retail stores and three distribution centers in the 
Midwest.  The acquisition will make O'Reilly one of the top ten auto parts 
chains in the country.  "Like O'Reilly, Hi/LO has been successful in pursuing a 
dual market strategy, and this fact, combined with their complementary 
geographic location, offers our company and our team members many excellent 
opportunities," stated David O'Reilly, President and Chief Executive Officer of 
O'Reilly.

Mike Young, Chief Executive Officer of Hi/LO, stated that "We are very pleased 
to be combining Hi/LO with the O'Reilly organization because their operating
philosophy is so similar to ours. We believe the transaction is in the best
interests of the Hi/LO stockholders, our associates and our customers."

Donaldson, Lufkin & Jenrette Securities Corporation is acting as advisor to 
O'Reilly, and will act as Dealer Manager for the tender offer.  Bank financing 
for the transaction will be provided by NationsBank.  SBC Warburg Dillon Read, 
Inc. served as financial advisor to Hi/LO and has provided a fairness opinion in
connection with the transaction.

The tender offer and merger are subject to customary conditions, including the 
tender of a majority of Hi/LO's shares and termination of the waiting period 
under U.S. antitrust laws.  The tender offer will be made pursuant to definitive
documents to be filed with the Securities and Exchange Commission.

The merger agreement was entered into by O'Reilly and Hi/LO after Hi/LO
terminated its previously announced merger with Discount Auto Parts, Inc. and
paid the required termination fee of $4 million.

Hi/LO sells automotive aftermarket parts, products and accessories for domestic 
and imported cars, vans and light trucks to "Do-It-Yourself" customers and 
commercial auto repair outlets.

O'Reilly is a leading specialty retailer and supplier of automotive aftermarket
parts, tools, supplies, equipment and accessories to both do-it-yourself
customers and professional mechanics and service technicians. Founded in 1957 by
the O'Reilly family, the company currently operates stores within the states of
Missouri, Arkansas, Kansas, Oklahoma, Nebraska and Iowa.

                           O'Reilly Automotive, Inc.

  Shamrock Acquisition, Inc., a Delaware corporation (the "Purchaser") which is 
a wholly owned subsidiary of O'Reilly Automotive Inc., a Missouri corporation 
("Parent"), is offering to purchase all outstanding shares of Common Stock, $.01
par value per share (the "Common Stock"), including the associated preferred 
stock purchase rights (the "Rights" and, together with the Common Stock, the 
"Shares"), of Hi-Lo Automotive, Inc., a Delaware corporation (the "Company"), at
a price of $4.35 per Share, net to the seller in cash, without interest thereon,
upon the terms and subject to the conditions set forth in the Offer to Purchase,
dated December 24, 1997 (the "Offer to Purchase"), and in the related Letter of 
Transmittal (which, together with any amendments or supplements thereto, 
collectively constitute the "Offer"). See the Offer to Purchase for capitalized 
terms used but not defined herein.

        THE OFFER AND WITHDRAWAL RIGHTS WILL EXPIRE AT 12:00 MIDNIGHT,
NEW YORK CITY TIME, ON MONDAY, JANUARY 26, 1998, UNLESS THE OFFER IS EXTENDED.

  The Offer is being made pursuant to an Agreement and Plan of Merger dated as 
of December 23, 1997 (the "Merger Agreement"), by and among Parent, the 
Purchaser and the Company. The Merger Agreement provides that, following 
consummation of the Offer and the satisfaction or waiver of the other conditions
to the Merger, the Purchaser will be merged with and into the Company (the
"Merger") and each outstanding Share (other than Shares held by the Company,
Parent, the Purchaser, or any other wholly owned subsidiary of Parent, and
Shares held by stockholders who perfect dissenters' rights under Delaware law)
will be converted into the right to receive $4.35 in each case, without interest
thereon, or any higher price paid in the Offer.

  The Board of Directors of the Company has unanimously approved the Offer and 
the Merger and determined that the terms of the Offer and the Merger are fair 
to, and in the best interests of, the Company and its stockholders and 
recommends that stockholders of the Company accept the Offer and tender their 
Shares.

  THE OFFER IS CONDITIONED UPON, AMONG OTHER THINGS, THERE HAVING BEEN VALIDLY
TENDERED AND NOT WITHDRAWN PRIOR TO THE EXPIRATION OF THE OFFER A NUMBER OF
SHARES WHICH REPRESENT A MAJORITY OF ALL OUTSTANDING SHARES, TOGETHER WITH
SHARES BENEFICIALLY OWNED BY PARENT AND PURCHASER, ON A FULLY DILUTED BASIS.

  For purposes of the Offer, the Purchaser shall be deemed to have accepted for 
payment, and thereby purchased, Shares properly tendered to the Purchaser and 
not withdrawn, as, if and when the Purchaser gives oral or written notice to 
ChaseMellon Shareholder Services, L.L.C. (the "Depositary"), of the Purchaser's 
acceptance for payment of such Shares. Upon the terms and subject to the 
conditions of the Offer, payment for Shares accepted pursuant to the Offer will 
be made by deposit of the purchase price therefor with the Depositary, which 
will act as agent for tendering stockholders for the purpose of receiving 
payment from the Purchaser and transmitting payment to tendering stockholders. 
In all cases, payment for Shares accepted for payment pursuant to the Offer will
be made only after timely receipt by the Depositary of (i) the certificate or 
timely Book-Entry Confirmation (as defined in the Offer to Purchase) with 
respect to such Shares, (ii) a Letter of Transmittal (or facsimile thereof), 
properly completed and duly executed, with any required signature guarantees, 
or, in the case of a book-entry transfer, an Agent's Message (as defined in the 
Offer to Purchase), and (iii) any other documents required by the Letter of 
Transmittal. Under no circumstances will interest be paid on the purchase price 
of the Shares, regardless of any extension of the Offer, or any delay in making 
such payment.

  Except as otherwise provided below, tenders of Shares are irrevocable. Shares 
tendered pursuant to the Offer may be withdrawn at any time prior to the 
Expiration Date and, unless theretofore accepted for payment and paid for by the
Purchaser pursuant to the Offer, may also be withdrawn at any time after
February 21, 1998. For a withdrawal to be effective, a written, telegraphic or
facsimile transmission notice of withdrawal must be timely received by the
Depositary at one of its addresses set forth in the Offer to Purchase and must
specify the name of the person having tendered the Shares to be withdrawn, if
different from the name of the person who tendered the Shares. If certificates
for Shares have been delivered or otherwise identified to the Depositary, then,
prior to the physical release of such certificates, the serial numbers shown on
such certificates must be submitted to the Depositary and, unless such Shares
have been tendered by an Eligible Institution (as defined in Section 3 of the
Offer to Purchase), the signatures on the notice of withdrawal must be
guaranteed by an Eligible Institution. If Shares have been delivered pursuant to
the procedure for book-entry transfer as set forth in Section 3 of the Offer to
Purchase, any notice of withdrawal must also specify the name and number of the
account at the appropriate Book-Entry Transfer Facility (as defined in the Offer
to Purchase) to be credited with the withdrawn Shares and otherwise comply 
with such Book-Entry Transfer Facility's procedures. Withdrawals of tenders of
Shares may not be rescinded, any Shares properly withdrawn will thereafter be
deemed not validly tendered for any purposes of the Offer. However, withdrawn 
Shares may be retendered by again following one of the procedures described in
Section 3 of the Offer to Purchase at any time prior to the Expiration Date. 
All questions as to form and validity (including time of receipt) of notices of
withdrawal will be determined by the Purchaser in its sole discretion, which 
determination will be final and binding.

  Subject to the terms of the Merger Agreement, the Purchaser expressly reserves
the right, in its sole discretion, at any time or from time to time, to extend 
the period of time during which the Offer is open by giving oral or written 
notice of such extension to the Depositary. The Merger Agreement provides that 
if the conditions to the Offer remaining unsatisfied prior to the Expiration 
Date, then if requested by the Company the Purchaser will extend the Offer from 
time to time until March 23, 1998. In addition, the Purchaser has the right to
extend the Offer for up to 10 business days if less than 90% of the Shares have
been tendered as of the Expiration Date. Any such extension will be followed as
promptly as practicable by public announcement thereof, such announcement to be
made no later than 9:00 a.m., New York City time, on the next business day after
the previously scheduled Expiration Date of the Offer. During any such
extension, all Shares previously tendered and not withdrawn will remain subject
to the Offer, subject to the rights of a tendering Stockholder to withdraw such
Shares.

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

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

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

  Questions and requests for assistance or for copies of the Offer to Purchase,
the Letter of Transmittal and other tender offer documents may be directed to
the Information Agent or the Dealer Manager, as set forth below and copies will
be furnished at the Purchaser's expense. No fees or commissions will be paid by

Chief Financial Officer and Treasurer
O'Reilly Automotive, Inc.

Re:  $175,000,000 Credit Facilities

Dear Jim:

You have advised us that O'Reilly Automotive, Inc. (the "O'Reilly") has formed a
corporation known as Newco and that Newco intends to make a tender offer in the
approximate amount of $50 million (the "Tender Offer") to acquire all of the
issued and outstanding shares of common stock, par value $.01 per share (the
"Shares") of Hi-Lo Automotive, Inc. ("Hi-Lo") and to merge Newco into Hi-Lo (the
"Merger") You have advised us that approximately $100 million in senior debt
financing will be required in order to effect the Acquisition, refinance certain
existing debt of Hi-Lo, to pay the costs and expenses related to the Acquisition
and to provide for ongoing general corporate purposes after completion of the
Acquisition and that no external financing will be obtained other than the
Senior Credit Facilities described below.

In connection with the foregoing, NationsBank, N.A. ("NationsBank" or the
"Agent") is pleased to advise you of its commitment to provide O'Reilly the full
principal amount of the Senior Credit Facilities described in the term sheet
attached hereto as Annex I (the "Term Sheet"). NationsBanc Montgomery
Securities, Inc. ("NMSI") is pleased to advise you of its commitment, as
Arranger and Syndication Agent for the Senior Credit Facilities, to form a
syndicate of financial institutions (the "Lenders") reasonably acceptable to you
for the Senior Credit Facilities.  All capitalized terms used and not otherwise
defined herein shall have the meanings set forth in the Term Sheet.

The commitments of NationsBank and NMSI hereunder are subject to the
satisfaction of each of the following conditions precedent in a manner
acceptable to NationsBank and NMSI in their sole discretion:

          (a) each of the terms and conditions set forth herein;

          (b) each of the terms and conditions set forth in the Term Sheet;
<PAGE>
 
O'Reilly Automotive, Inc.
December 20, 1997
Page 2


          (c) execution by O'Reilly, Newco, Hi-Lo and/or other appropriate
     parties of the definitive Merger Agreement and other related documentation
     relating to the Acquisition and Merger, in form and substance reasonably
     satisfactory to NationsBank and NMSI;

          (d) execution of a fee letter among O'Reilly, NationsBank and NMSI
     prior to or concurrently with the acceptance of this letter by O'Reilly and
     Newco;

          (e) the negotiation, execution and delivery of definitive
     documentation with respect to the Senior Credit Facilities consistent with
     the Term Sheet and otherwise reasonably satisfactory to NationsBank and
     NMSI; and

          (f) there shall not have occurred and be continuing since the date
     hereof a material disruption of, or a material adverse change in,
     financial, banking or capital market conditions, in each case as determined
     by NationsBank and NMSI in their reasonable discretion which would
     adversely affect NMSI's ability to syndicate the Senior Credit Facilities.

NationsBank will act as Agent for the Senior Credit Facilities and NMSI will act
as Arranger and Syndication Agent for the Senior Credit Facilities.  No
additional agents will be appointed without the prior approval of NationsBank
and NMSI.

Furthermore, the commitments of NationsBank and NMSI hereunder are based upon
the financial and other information regarding O'Reilly, Newco, Hi-Lo and their
subsidiaries previously provided to NationsBank and NMSI and are subject to the
condition, among others, that there shall not have occurred after the date of
such information, in the opinion of NationsBank and NMSI, any material adverse
change in the business, assets, liabilities (actual or contingent), operations,
condition (financial or otherwise) or prospects of O'Reilly, Newco, Hi-Lo and
their subsidiaries taken as a whole.  If the continuing review by NationsBank
and NMSI of O'Reilly, Newco, Hi-Lo and their subsidiaries discloses information
relating to conditions or events not previously disclosed to NationsBank and
NMSI or relating to new information or additional developments concerning
conditions or events previously disclosed to NationsBank and NMSI which
NationsBank and NMSI in their reasonable discretion believe would have a
material adverse effect on the condition (financial or otherwise), assets,
properties, business, operations or prospects of O'Reilly, Newco, Hi-Lo and
their subsidiaries taken as a whole, NationsBank and NMSI may, in their sole
discretion, suggest alternative financing amounts or structures that ensure
adequate protection for the Lenders or decline to participate in the Senior
Credit Facilities.

You agree to actively assist NationsBank and NMSI in achieving a syndication of
the Senior Credit Facilities that is satisfactory to NationsBank, NMSI and you.
In the event that such syndication cannot be achieved in a manner satisfactory
to NationsBank and NMSI under the structure outlined in the Term Sheet you agree
to cooperate with NationsBank and NMSI in developing an alternative structure
reasonably acceptable to each party that will permit a

satisfactory syndication of the Senior Credit Facilities.  Syndication of the
Senior Credit Facilities will be accomplished by a variety of means, including
direct contact during the syndication between senior management and advisors of
O'Reilly, Newco and the proposed Lenders. To assist NationsBank and NMSI in the
syndication efforts, you hereby agree to (a) provide and cause your advisors to
provide NationsBank and NMSI and the other Lenders upon request with all
information reasonably deemed necessary by NationsBank and NMSI to complete
syndication, (b) assist NationsBank and NMSI upon their reasonable request in
the preparation of an Information Memorandum to be used in connection with the
syndication of the Senior Credit Facilities and (c) otherwise assist NationsBank
and NMSI in their syndication efforts, including by making available officers
and advisors of O'Reilly, Newco, Hi-Lo and their subsidiaries from time to time
to attend and make presentations regarding the business and prospects of
O'Reilly, Newco, Hi-Lo and their subsidiaries, as appropriate, at a meeting or
meetings of prospective Lenders. You further agree to refrain from engaging in
any additional financings for O'Reilly, Newco, Hi-Lo and their subsidiaries
during such syndication process unless otherwise agreed to by NationsBank and
NMSI.

It is understood and agreed that NationsBank and NMSI, after consultation with
you, will manage and control all aspects of the syndication, including decisions
as to the selection of proposed Lenders and any titles offered to proposed
Lenders, when commitments will be accepted and the final allocations of the
commitments among the Lenders. It is understood that no Lender participating in
the Senior Credit Facilities will receive compensation from you outside the
terms contained herein and in the Term Sheet in order to obtain its commitment.
It is also understood and agreed that the amount and distribution of the fees
among the Lenders will be at the sole discretion of NationsBank and NMSI and
that any syndication prior to execution of definitive documentation will reduce
the commitment of NationsBank.

You hereby represent, warrant and covenant that to your best knowledge and
belief (i) all information, other than Projections (as defined below), which has
been or is hereafter made available to NationsBank and NMSI or the Lenders by
you or any of your representatives in connection with the transactions
contemplated hereby ("Information") is and will be complete and correct in all
material respects and does not and will not contain any untrue statement of a
material fact or omit to state a material fact necessary to make the statements
contained therein not misleading and (ii) all financial projections concerning
O'Reilly, Newco and their subsidiaries (including Hi-Lo) that have been or are
hereafter made available to NationsBank and NMSI or the Lenders by you or any of
your representatives (the "Projections") have been or will be prepared in good
faith based upon reasonable assumptions. You agree to furnish us with such
Information and Projections as we may reasonably request and to supplement the
Information and the Projections from time to time until the closing date for the
Senior Credit Facilities so that the representation and warranty in the
preceding sentence is correct on such date. In arranging and syndicating the
Senior Credit Facilities, NationsBank and NMSI will be using and relying on the
Information and the Projections without independent verification thereof.

joint or several, related to or arising out of any matters contemplated by this
letter (including any arising out of the negligence of any Indemnified Party),

the Senior Credit Facilities shall be executed and delivered and notwithstanding
the termination of this letter or the commitments of NationsBank and NMSI
hereunder.

disclosed to or relied upon by any other person or entity other than your
accountants, attorneys and other advisors, without the prior written consent of

Syndication Agent for the Senior Credit Facilities.  NationsBank reserves the
right to allocate, in whole or in part, to NMSI certain fees payable to
NationsBank in such manner as NationsBank and NMSI agree in their sole
discretion.  You acknowledge and agree that NationsBank may share with any of
its affiliates (including specifically NMSI) any information relating to the
Senior Credit Facilities, O'Reilly, Newco, Hi-Lo and their subsidiaries and
affiliates.

NationsBank, NMSI and O'Reilly.

Except as required by applicable law, this letter, the Term Sheet, and the Fee

third party without the prior consent of NationsBank and NMSI, other than to

Re:  Commitment Letter, dated December 20, 1997, among O'Reilly Automotive, Inc.
     ("O'Reilly"), Shamrock Acquisition, Inc. ("Newco"), NationsBank, N.A.,
     ("NationsBank") and NationsBanc Montgomery Securities, Inc. ("NMSI")

Dear Jim:

This letter is delivered to you in connection with your request that we provide
the above-referenced Commitment Letter (the "Commitment Letter") regarding
arrangement and syndication of credit facilities in an aggregate principal
amount of $175,000,000 (the "Senior Credit Facilities") for O'Reilly.  A summary
of proposed terms relating to the Facilities is attached to the Commitment
Letter as Annex I (the "Term Sheet").  Unless otherwise defined herein,
capitalized terms shall have the meanings set forth in the Commitment Letter and
the Term Sheet.  In connection with, and in consideration of the agreements
contained in the Commitment Letter, O'Reilly and Newco agree with NationsBank
and NMSI as follows:

     1.   Underwriting Fee:  O'Reilly will pay, or cause to be paid, to
NationsBank for its own account, a fee of 55 bps on the entire amount of the
Senior Credit Facilities.  Such fee shall be for underwriting, structuring and
syndicating the Senior Credit Facilities.  The fee shall be due and payable upon
the closing of the Senior Credit Facilities.

Alternatively, in the event that (a) O'Reilly, Newco or any of your affiliates
(collectively the "Related Parties") consummate the Acquisition or any part of
the Tender Offer without NationsBank acting as administrative and collateral
agent or without NMSI acting as arranger and syndication agent for any senior
credit facilities utilized to complete the Acquisition or any part of the Tender
Offer notwithstanding a willingness on the part of NationsBank to provide and
NMSI to arrange the Senior Credit Facilities for the Acquisition or Tender Offer
in accordance with the Commitment Letter and the Term Sheet, or (b) any Related
Party consummates any similar transaction in which any Related Party acquires,
directly or indirectly, all or any substantial portion of the stock or assets of
Hi-Lo (any such transaction an "Alternate Transaction") without NationsBank
acting as administrative and collateral agent or without NMSI acting as arranger
and syndication agent for any senior credit facilities utilized to complete such
Alternate Transaction, you agree in each case to pay to NationsBank a fee of
$500,000 in immediately payable funds, immediately upon the consummation of any
part of the Tender Offer, Acquisition or Alternate Transaction.  You also agree
that if any 
<PAGE>

Page 2
 
Related Party enters into a definitive agreement for the Acquisition
or any Alternate Transaction that provides for the payment of a so-called
"topping fee", "break-up fee", or any similar termination fee or the
payment or any other form of consideration (including reimbursement of expenses)
in the event that the Acquisition or such Alternate Transaction is not
consummated, you agree to pay (or cause the other Related Parties to pay) to
NationsBank, in immediately available funds, upon receipt by any Related Parties
of such fees or other consideration, a fee equal to the lesser of (A) $500,000
or (B) an amount equal to 15% of such "topping fees", "break-up fees", other
termination fees or other forms of consideration received by the Related
Parties.

     2.   Administrative Fee:  O'Reilly will pay an annual administrative fee of
$35,000 to NationsBank, for its own account as Agent for the Banks under the
Facilities, annually in advance on the date of closing of the Facilities and on
each anniversary date thereafter, until the Facilities terminate.

If the foregoing is in accordance with your understanding, please sign and
return the enclosed duplicate copy of this letter.

Very truly yours,

NATIONSBANK, N.A.

                          AGREEMENT AND PLAN OF MERGER


     THIS AGREEMENT AND PLAN OF MERGER, dated as of December 23, 1997 (this
"Agreement"), is among O'REILLY AUTOMOTIVE, INC., a Missouri corporation
("O'Reilly"), SHAMROCK ACQUISITION, INC., a Dela  ware corporation and a wholly-
owned subsidiary of O'Reilly ("Sub"), and HI-LO AUTOMOTIVE, INC., a Delaware
corporation ("Hi-Lo").

     WHEREAS, the Board of Directors of each of O'Reilly, Sub and Hi-Lo, has,
subject to the conditions set forth in this Agreement, unanimously deter  mined
that it is in the best interests of their respective stockholders for Sub to
acquire Hi-Lo on the terms and subject to the conditions set forth herein; and

     WHEREAS, in furtherance thereof, it is proposed that Sub shall make a
tender offer (the "Offer") to acquire all of the outstanding shares (the
"Shares") of Common Stock, par value $.01 per share (the "Hi-Lo Common Stock"),
of Hi-Lo, together with the associated Rights (as hereinafter defined), at  a
price of $4.35 per share (such amount, or any greater amount per share paid
pursuant to the Offer, being hereinafter referred to as the "Per Share Amount"),
net to the seller in cash, in accordance with the terms and subject to the
conditions of this Agreement; and

     WHEREAS, the parties desire to make certain representations, warranties,
covenants and agreements in connection with the Offer and the Merger (as
hereinafter defined) and also to prescribe various conditions to the Offer and
the Merger.

     NOW, THEREFORE, in consideration of the mutual agreements, provisions and
covenants contained in this Agreement, the parties hereby agree as follows:

                                       5
<PAGE>
 
                                   ARTICLE I

                                   THE OFFER

     Section 1.1  The Offer.

     (a) Provided that this Agreement shall not have been terminated in
accordance with Section 8.1, Sub shall commence, within the meaning of Rule 14d-
2 under the Securities Exchange Act of 1934, as amended (the "Ex  change Act"),
the Offer as promptly as practicable (but in no event later than the fifth
business day from and including the date of initial public announcement of this
Agreement).  Sub shall accept for payment Shares which have been validly
tendered and not withdrawn pursuant to the Offer following expiration of the
Offer promptly following the time that all conditions to the Offer shall have
been satisfied or waived by Sub (except that the Minimum Condition (as
hereinafter defined) may not be waived).  The obligation of Sub to accept for
payment, purchase and pay for Shares tendered pursuant to the Offer shall be
subject only to the conditions set forth in Annex A and to the further condition
that a number of Shares which, together with any Shares beneficially owned by
O'Reilly or Sub, represent not less than a majority of the Shares then
outstanding on a Fully Diluted Basis (as hereinafter defined) shall have been
validly tendered and not withdrawn prior to the final expiration date of the
Offer (the "Minimum Condition").  Unless previously approved by Hi-Lo in
writing, no change in the Offer may be made (i) which decreases the price per
Share payable in the Offer, (ii) which changes the form of consideration to be
paid in the Offer, (iii) which reduces the maximum number of Shares to be
purchased in the Offer or the Minimum Condition, (iv) which imposes conditions
to the Offer in addition to those set forth in Annex A hereto or which modifies
the conditions set forth in Annex A in a manner adverse to the holders of Shares
or (v) which amends any other term of the Offer in a manner adverse to the
holders of the Shares.  Notwithstanding the foregoing, Sub shall and O'Reilly
agrees to cause Sub to, if requested by Hi-Lo, extend the Offer from time to
time until 90 days from the commencement of the Offer if and to the extent that,
at the then scheduled expiration date (the initial scheduled expiration date
being 20 business days following commencement of the Offer), any of the
conditions to Sub's obligation to accept for payment and pay for the Shares
shall not be satisfied or waived, until such time as such conditions are
satisfied or waived.  If any of the conditions to Sub's obligation to accept for
payment and pay for the Shares are not satisfied or waived upon the expiration
of 90 days after the commencement of the Offer, Sub may, in its sole discretion,
extend the Offer until such time as such conditions are satisfied or waived.
Additionally, notwith  standing that all conditions to the Offer are satisfied
as of the expiration date of the

                                       6
<PAGE>
 
Offer (as it may have been previously extended), Sub may extend the Offer,
without the consent of Hi-Lo,  (a) for a period not to exceed ten business days
if the Shares tendered and not withdrawn pursuant to the Offer equal less than
90% of the out  standing Shares and (b) for a period not to exceed five business
days if an Adverse Market Change (as hereinafter defined) shall have occurred,
and be continuing on the scheduled expiration date of the Offer, and at the time
of such extension pursuant to (a) or (b) the Sub waives the satisfaction of the
condition set forth in clause (c) of Annex A and its right to terminate the
Merger Agreement pursuant to Section 8.1(e). Subject to the terms and conditions
of the Offer and this Agreement, Sub shall, and O'Reilly shall cause Sub to, pay
for all Shares validly tendered and not withdrawn pursuant to the Offer that Sub
becomes obligated to purchase pursuant to the Offer as soon as practicable after
the expiration of the Offer.

     (b) As used herein, the following terms shall have the meaning set forth
herein:

     "Adverse Market Change" shall mean  any general suspension of trading in,
or limitation on prices for, securities on the New York Stock Exchange or the
NASDAQ National Market,  a declaration of a banking moratorium or any suspension
of payments in respect of banks in the United States (whether or not mandatory),
(1)  a commencement or escalation of a war, armed hostilities or other
international or national calamity directly involving the United States and
having an adverse effect on the financial markets in the United States,  any
material limitation (whether or not mandatory) by any governmental authority,
agency or commission ("Governmental Entity"), on the extension of credit by
banks or other lending institutions in the United States, and  in the case of
any of the foregoing existing at the time of the commencement of the Offer, a
material acceleration or worsening thereof;

     "Fully Diluted Basis" shall mean as of any time all of the Shares plus all
shares of Hi-Lo Common Stock issuable upon exercise of outstanding options to
acquire Hi-Lo Common Stock minus 587,566 shares of Hi-Lo Common Stock issuable
upon exercise of options which the holder thereof has irrevocably agreed in
writing, in a form satisfactory to O'Reilly, not to exercise.

     (c) As soon as practicable on the date of commencement of the Offer,
O'Reilly and Sub shall file with the Securities and Exchange Commission (the
"SEC") a Tender Offer Statement on Schedule 14D-1 with respect to the Offer
(together with any supplement or amendments thereto, the "Schedule 14D-1"). The
Schedule 14D-1 will include, as exhibits, the Offer to Purchase, form of letter
of

                                       7
<PAGE>
 
transmittal and summary advertisement (collectively, together with any
amendments and supplements thereto, the "Offer Documents").  The Offer Documents
will comply in all material respects as to form with the requirements of
applicable federal securities laws.  O'Reilly, Sub and Hi-Lo each agree promptly
to correct any information provided by them for use in the Offer Documents if
and to the extent that it shall have become false or misleading in any material
respect and O'Reilly and Sub agree to take all steps necessary to cause the
Offer Documents and any amendments or supplements thereto to be filed with the
SEC and to be disseminated to holders of Shares, in each case as and to the
extent required by applicable federal securities laws.  Hi-Lo and its counsel
shall be given a reasonable opportunity to review and comment upon the Offer
Documents and any amendments thereto in each case prior to the filing thereof
with the SEC.  O'Reilly and Sub agree to provide Hi-Lo and its counsel a written
copy of any comments or other communications (whether written or oral) that
O'Reilly, Sub or their counsel may receive from time to time from the SEC or its
Staff with respect to the Offer Documents as soon as practicable after receipt
thereof.

     Section 1.2  Hi-Lo Action.
     
     (a) Hi-Lo hereby approves of and consents to the Offer and represents that
the Board of Directors, including all of the disinterested directors, at a
meeting duly called and held, has, subject to the terms and conditions set forth
herein, (i) approved this Agreement and the transactions contemplated hereby,
including the Offer and the Merger (as defined in Section 2.1) and such approval
constitutes approval of this Agreement and the transactions contemplated hereby,
including the Offer and the Merger, for purposes of Section 203 of the Delaware
General Corporation Law, as amended (the "DGCL"), such that it will not apply to
the transactions contemplated by this Agreement, (ii) unanimously determined
that each of the Offer and the Merger are fair to and in the best interests of
Hi-Lo and Hi-Lo's stockholders, and (iii) resolved to recommend that the
stockholders of Hi-Lo accept the Offer, tender their Shares thereunder to Sub
and approve and adopt this Agreement and the Merger; provided, that such
recommendation may be withdrawn, modified or amended if, Hi-Lo determines in
good faith, based on advice of its outside counsel, that such action is
necessary in order for the Board of Directors of Hi-Lo to comply with its
obligations or duties to Hi-Lo and Hi-Lo's stockholders under applicable law.
Hi-Lo consents to the inclusion of such recommendation and approval in the Offer
Documents, subject to Hi-Lo's right to withdraw, modify or amend its
recommendation.

                                       8
<PAGE>
 
     (b) Hi-Lo hereby agrees to file with the SEC, concurrently with the
commencement of the Offer, a Solicitation/Recommendation Statement on Schedule
14D-9 (together with any amendments or supplements thereto, the "Schedule 14D-
9") containing the recommendation described in Section 1.2(a).  The Schedule
14D-9 will comply in all material respects as to form with the requirements of
applicable federal securities laws.  Hi-Lo, O'Reilly and Sub each agree promptly
to correct any information provided by them for use in the Schedule 14D-9 if and
to the extent that it shall have become false or misleading in any material
respect and Hi-Lo further agrees to take all steps necessary to cause the
Schedule 14D-9 and any amendments or supplements thereto to be filed with the
SEC and disseminated to holders of Shares, in each case as and to the extent
required by applicable federal securities laws.  Notwithstanding anything to the
contrary in this Agreement, the Board of Directors may withdraw, modify or amend
its recommendation if Hi-Lo reasonably determines in good faith, based on advice
of its outside counsel, that such action is necessary in order for the Board of
Directors of Hi-Lo to comply with its obligations or duties to Hi-Lo and Hi-Lo's
stockholders under applicable law. O'Reilly and its counsel shall be given a
reasonable opportunity to review and comment upon the Schedule 14D-9 and any
amendments thereto in each case prior to the filing thereof with the SEC.  Hi-Lo
agrees to provide O'Reilly and Sub and their counsel a written copy of any
comments or other communications (whether written or oral) that Hi-Lo or its
counsel may receive from time to time from the SEC or its Staff with respect to
the Schedule 14D-9 as soon as practicable after receipt thereof.

     (c) In connection with the Offer, Hi-Lo will promptly furnish O'Reilly and
Sub with mailing labels, security position listings and any available listing or
computer files containing the names and addresses of the record holders of the
Shares as of a recent date and shall furnish Sub with such additional
information and assistance (including, without limitation, updated lists of
stockholders, mailing labels and lists of securities positions) as Sub or its
agents may reason  ably request in communicating, and advocating acceptance of
the Offer to the record and beneficial holders of Shares.  Subject to the
requirements of applicable law, and except for such steps as are necessary to
disseminate the Offer Documents, O'Reilly and Sub shall hold such listings and
other information in confidence and in accordance with the terms of the Hi-Lo
Confidentiality Agreement (as hereinafter defined), and shall use the
information contained in any such labels, listings and files only in connection
with the Offer and the Merger, and, if this Agreement is terminated, will
deliver to Hi-Lo all copies of such information (and extracts and summaries
thereof) then in their or their agent's or advisor's possession in accordance
with the terms of the Hi-Lo Confidentiality Agreement.

     Section 1.3  Directors.

     (a) Promptly upon the purchase of and payment for any Shares by O'Reilly or
any of its Subsidiaries which represent at least a majority of the outstanding
Shares on a fully diluted basis, O'Reilly shall be entitled to designate such
number of directors, rounded up to the next whole number, on the Board of
Directors of Hi-Lo as is equal to the product of the total number of directors
on such Board (giving effect to the directors designated by O'Reilly pursuant to
this sentence) multiplied by the percentage that the number of Shares so
purchased bears to the total number of Shares then outstanding on a fully
diluted basis.  In furtherance thereof, Hi-Lo shall, upon request of Sub, use
its best efforts promptly either (at Hi-Lo's election) to increase the size of
its Board of Directors or secure the resignations of such number of its
incumbent directors, or both, as is necessary to enable O'Reilly's designees to
be so elected to Hi-Lo's Board, and shall take all actions available to Hi-Lo to
cause O'Reilly's designees to be so elected.  At such time, Hi-Lo shall, if
requested by O'Reilly, also cause persons designated by O'Reilly to constitute
at least the same percentage (rounded up to the next whole number) as is on Hi-
Lo's Board of Directors of (i) each committee of Hi-Lo's Board of Directors,
(ii) each board of directors (or similar body) of each Subsidiary (as defined in
Section 9.11) of Hi-Lo and (iii) each committee (or similar body) of each such
board.

     (b) Hi-Lo's obligations to appoint designees to the Board of Directors of
Hi-Lo shall be subject to Section 14(f) of the Exchange Act.  At the request
and expense of O'Reilly, Hi-Lo shall promptly take all actions required pursuant
to Section 14(f) of the Exchange Act and Rule 14f-1 promulgated thereunder in
order to fulfill its obligations under Section 1.3(a), including mailing to
stockholders the information required by such Section 14(f) and Rule 14f-1 as is
necessary to enable O'Reilly's designees to be elected to Hi-Lo's Board of
Directors. O'Reilly or Sub will supply Hi-Lo and be solely responsible for any
information with respect to either of them and their nominees, officers,
directors and affiliates required by such Section 14(f) and Rule 14f-1.

     (c)  In the event that O'Reilly's designees are elected or appointed to
Hi-Lo's Board of Directors, until the Effective Time (as defined in Section
2.3), Hi-Lo's Board shall include at least two directors who are directors on
the date hereof (the "Independent Directors"), provided that, in such event, if
the number of Independent Directors shall be reduced below two for any reason
whatsoever, any remaining Independent Directors (or Independent Director, if
there shall be only one remaining) shall be entitled to designate persons to
fill such vacancies who shall be deemed to be Independent Directors for purposes
of this Agreement or, if no Inde-

                                      10
<PAGE>
 
pendent Director then remains, the other directors shall designate two persons
to fill such vacancies who shall not be stockholders, affiliates or associates
of O'Reilly or Sub and such persons shall be deemed to be Independent Directors
for purposes of this Agreement. Notwithstanding anything in this Agreement to
the contrary, in the event that O'Reilly's designees are elected to Hi-Lo's
Board, after the acceptance for payment of Shares pursuant to the Offer and
prior to the Effective Time, the affirmative vote of a majority of the
Independent Directors shall be required and shall be sufficient to authorize,
any termination of this Agreement by Hi-Lo, any amendment of this Agreement
requiring action by the Board of Directors of Hi-Lo, any extension of time for
the performance of any of the obligations or other acts of O'Reilly or Sub under
this Agreement, any waiver of compliance with any of the agreements or
conditions under this Agreement for the benefit of Hi-Lo, any action to seek to
enforce any obligation of O'Reilly or Sub under this Agreement and any other
action by Hi-Lo's Board of Directors under or in connection with this Agreement.
The Independent Directors shall be appointed as a Special Committee of the Hi-Lo
Board of Directors and shall have full power solely with respect to the matters
set forth in the previous sentence to be approved by the Independent Directors.
In connection herewith, the Independent Directors (in their capacity as the
Special Committee) shall be authorized, on behalf of and at the expense of Hi-
Lo, to retain legal advisors.

<PAGE>
 
     (a) Each Share, together with any preferred stock purchase rights (the
"Rights"), issued pursuant to the Rights Agreement, dated as of August 28, 1996,
by and between Hi-Lo and ChaseMellon Shareholder Services, L.L.C. as Rights
Agent (the "Rights Agreement"), that are issued and outstanding immediately

wholly owned subsidiary of O'Reilly (collectively, "O'Reilly Companies") or any
of Hi-Lo's direct or indirect wholly owned subsidiaries or shares held in the

part of Sub, Hi-Lo or the holder thereof, be cancelled and extinguished and
converted into the right to receive the Per Share Amount in cash (the "Merger
Consideration"), payable to the holder thereof, without interest thereon, less
any applicable withholding of taxes, upon the surrender of the certificate
formerly representing such Share in the manner provided in Section 3.3.

     (b) Each Share (and Rights) issued and outstanding and owned by O'Reilly or
any of O'Reilly's direct or indirect wholly owned subsidiaries or any of Hi-Lo's
direct or indirect wholly owned subsidiaries or authorized but unissued shares

     (c) Each share of common stock of Sub issued and outstanding immediately

     Section 3.2  Stockholders Meeting.   Hi-Lo, acting through its Board of
Directors, shall, if required by applicable law in order to consummate the
Merger:

          (i)  duly call, give notice of, convene and hold a special meeting of
     its stockholders (the "Stockholders Meeting"), to be held as soon as
     practicable after Sub shall have purchased Shares pursuant to the Offer,
     for the purpose of considering and taking action upon this Agreement;
 
          (ii)  prepare and file with the SEC a preliminary proxy or information
     statement relating to the Merger and this Agreement and include in any
     preliminary or definitive proxy statement or

                                      13
<PAGE>
 
     information statement with respect to the Stockholders' Meeting (the "Proxy
     Statement"), the recommendation of the Board of Directors that stockholders
     of Hi-Lo vote in favor of the approval of this Agreement and the
     transactions contemplated hereby unless the Board of Directors of Hi-Lo
     determines in good faith, based on advice of its outside counsel, that not
     taking any such action is necessary in order for the Board of Directors of
     Hi-Lo to comply with its obligations or duties to Hi-Lo and Hi-Lo's
     stockholders under applicable law; and

          (iii)  use all reasonable efforts to obtain and furnish the
     information required to be included by it in the Proxy Statement and, after
     consultation with O'Reilly and Sub, respond promptly to any comments made
     by the SEC with respect to the Proxy Statement and any preliminary version
     thereof and cause the Proxy Statement to be mailed to its stockholders at
     the earliest practicable time following the expiration or termination of
     the Offer and obtain the necessary approvals by its stockholders of this
     Agreement and the transactions contemplated hereby unless the Board of
     Directors of Hi-Lo determines in good faith, based on advice of its outside
     counsel, that not taking any such action is necessary in order for the
     Board of Directors of Hi-Lo to comply with its obligations or duties to Hi-
     Lo and Hi-Lo's stockholders under applicable law.

     (a) O'Reilly agrees that it will provide Hi-Lo with the information
concerning O'Reilly and Sub required by applicable law to be included in the
Proxy Statement.

     Hi-Lo and O'Reilly agree to use commercially reasonable efforts to cause
the Special Meeting to occur within 90 days after the purchase of Shares
pursuant to the Offer.  At the Stockholders' Meeting, O'Reilly, Sub and their
affiliates will vote all Shares owned by them in favor of approval of this
Agreement and the transactions contemplated hereby.

     (b) Notwithstanding the foregoing, in the event that O'Reilly, Sub and any
of their Subsidiaries shall acquire at least 90% of the then outstanding Shares,
the parties hereto agree subject to Article VII, to take all necessary and
appropriate action to cause the Merger to become effective, in accordance with
Section 253 of the DGCL, as soon as practicable after such acquisition, without
a meeting of the stockholders of Hi-Lo.

                                      14
<PAGE>
 
     Section 3.3  Payment for Shares in the Merger.  The manner of making
payment for Shares in the Merger shall be as follows:

     (a) At or prior to the Effective Time, O'Reilly shall deposit with
ChaseMellon Shareholder Services, L.L.C. (the "Exchange Agent"), or such other
exchange agent selected by O'Reilly and reasonably acceptable to Hi-Lo, for the
benefit of the holders of Shares, the funds necessary to make the payments
contemplated by Section 3.1 (the "Exchange Fund").  The Exchange Agent shall,
pursuant to irrevocable instructions, deliver the Merger Consideration out of
the Exchange Fund.

     (b) As soon as practicable after the Effective Time, but in any event no
later than five (5) business days thereafter, the Exchange Agent shall mail to
each holder of record (other than holders of certificates representing Shares
referred to in Section 3.1(b)) of a certificate or certificates which
immediately prior to the Effective Time represented outstanding Shares (the
"Certificates")  a letter of transmittal (which shall specify that delivery
shall be effected, and risk of loss and title to the Certificates shall pass,
only upon proper delivery of the Certificates to the Exchange Agent and shall be
in such form and have such other customary provisions as O'Reilly and Hi-Lo may
reasonably specify) and (ii) instructions for use in effecting the surrender of
the Certificates in exchange for payment of the Merger Consideration.  Upon
surrender of a Certificate for cancellation to the Exchange Agent, together with
such letter of transmittal, duly executed, and such other documents as may
reasonably be required by the Exchange Agent, the holder of such Certificate
shall be entitled to receive in exchange therefor the Merger Consideration
without any interest thereon, less any applicable withholding of taxes, and the
Certificate so surrendered shall forthwith be canceled.  The Merger
Consideration with respect to the Shares represented thereby may be paid to a
person other than the person in whose name the Certificate so surrendered is
registered if such Certificate shall be properly endorsed or otherwise be in
proper form for transfer and the person requesting such issuance shall pay any
transfer or other nonincome taxes required by reason of the payment of the
Merger Consideration to a person other than the registered holder or establish
to the satisfaction of the Exchange Agent that such tax has been paid or is not
applicable.  Until surrendered as contemplated by this Section 3.3, each
Certificate shall be deemed at any time after the Effective Time to represent
only the right to receive upon such surrender thereof, the Merger Consideration
with respect to each of the Shares represented thereby.

                                      15
<PAGE>
 
     (c) Any portion of the Exchange Fund which remains undistributed to the
holders of the Certificates as of the date which is one year after the Effective
Time shall be delivered to O'Reilly, upon demand, and any holders of the
Certificates who have not \theretofore complied with this Article III shall
thereafter look only to O'Reilly or the Surviving Corporation for payment of
their claim for Merger Consideration.

     (d) None of O'Reilly, Hi-Lo, Sub or the Exchange Agent shall be liable to
any person in respect of any cash from the Exchange Fund delivered to a public
official pursuant to any applicable abandoned property, escheat or similar law.
If any Certificate shall not have been surrendered prior to seven years after
the Effective Time (or immediately prior to such earlier date on which any
Merger Consideration, would otherwise escheat to or become the property of any
govern  mental body or authority) any such Merger Consideration, to the extent
permitted by applicable law, shall become the property of the Surviving
Corporation, free and clear of all claims or interest of any person previously
entitled thereto.

     (e) The Exchange Agent shall invest any cash included in the Exchange Fund,
as directed by O'Reilly, on a daily basis.  Any interest and other income
resulting from such investments shall be paid to O'Reilly.

     (f) If any Certificate shall have been lost, stolen or destroyed, upon the
making of an affidavit of that fact by the person claiming such Certificate to
be lost, stolen or destroyed and, if required by the Surviving Corporation,
the posting by such person of a bond in such reasonable amount as the Surviving
Corporation may direct as indemnity against any claim that may be made against
it with respect to such Certificate, the Exchange Agent will issue in exchange
for such lost, stolen or destroyed Certificate the Merger Consideration.

     Section 3.4  Transfer of Shares After the Effective Time.  No transfers of
Shares shall be made on the stock transfer books of Hi-Lo after the Effective
Time.

     Section 3.5  Stock Options and Associate Purchase Plan.

     (a) Each option granted to a Hi-Lo employee, consultant or director to
acquire shares of Hi-Lo Common Stock ("Option") that is outstanding immediately
prior to the purchase of Shares pursuant to the Offer (irrespective of whether
such Options are then exercisable) shall on the fifth business day after the
purchase by Sub of Shares pursuant to the Offer be cancelled in exchange for a
single

                                      16
<PAGE>
 
lump sum cash payment equal to the product of (i) the number of shares of Hi-Lo
Common Stock subject to such Option and (ii) the excess of the Per Share Amount
over the exercise price per share of such Option.

     (b) Except as set forth in Section 3.5(a), each Option that is outstanding
immediately prior to the Effective Time, whether or not then vested or
exercisable, shall, effective as of the Effective Time, be cancelled and no
payments shall be made with respect thereto;

     (c) Hi-Lo has taken all actions so that following the purchase of Shares
pursuant to the Offer no holder of employee stock options will have any right to
receive Shares upon exercise of an employee stock option; and

     (d) Outstanding purchase rights under Hi-Lo's 1991 Associate Stock Purchase
Plan (the "Associate Purchase Plan")  (i) shall be exercised at the next
scheduled date of exercise under the Associate Purchase Plan or (ii) shall be
terminated.  No purchase rights shall be granted or exercised under the
Associate Purchase Plan following such exercise date, and the Associate Purchase
Plan shall be terminated as soon as practicable thereafter.

     Section 3.6  Dissenting Shares.  Notwithstanding anything in this Agreement
to the contrary, any Shares which are held by stockholders who did not vote in
favor of the Merger and who comply with all of the relevant provisions of
Section 262 of the DGCL (the "Dissenting Shares") shall not be converted into or
be exchanged for the right to receive the Merger Consideration (but instead
shall be converted into the right to receive payment from the Surviving
Corporation with respect to such Dissenting Shares in accordance with the DGCL),
unless and until such holders shall have failed to perfect or shall have
effectively withdrawn or lost their rights to appraisal under the DGCL.  If any
such holder shall have failed to perfect or shall have effectively withdrawn or
lost such right, such holder's Shares shall be entitled to the Merger
Consideration in accordance with Section 3.3.  Hi-Lo shall give prompt notice to
Sub and O'Reilly of any demands received by Hi-Lo for appraisal of Shares, and
Sub and O'Reilly shall have the right to participate in and direct all
negotiations and proceedings with respect to such demands.  Hi-Lo shall not,
except with the prior written consent of Sub and O'Reilly, make any payments
with respect to, or settle or offer to settle, any such demands.

                             ARTICLE IV

                    REPRESENTATIONS AND WARRANTIES OF HI-LO

     Hi-Lo represents and warrants to O'Reilly and Sub that:

     Section 4.1  Organization, Qualification, Etc.  Hi-Lo is a corporation duly
organized, validly existing and in good standing under the laws of the State of
Delaware and has the corporate power and authority to own its properties and
assets and to carry on its business as it is now being conducted and is duly
qualified to do business and is in good standing in each jurisdiction in which
the ownership of its properties or the conduct of its business requires such
qualification, except for jurisdictions in which such failure to be so qualified
or to be in good standing would not, individually or in the aggregate, have a
Material Adverse Effect (as hereinafter defined) on Hi-Lo. As used in this
Agreement, any reference to any state of facts, event, change or effect having a
"Material Adverse Effect" on or with respect to Hi-Lo or O'Reilly, as the case
may be, means a material adverse effect on the business, results of operations
or financial condition of Hi-Lo and its Subsidiaries (as defined in Section
9.11), taken as a whole, or O'Reilly and its Subsidiaries, taken as a whole, as
the case may be. Hi-Lo has heretofore furnished, or otherwise made available, to
O'Reilly a complete and correct copy, as applicable, of the Certificate or
Articles of Incorporation, the By-laws, the Certificate of Limited Partnership,
and/or the Limited Partnership Agreement, each as amended to, and in full force
and effect as of, the date hereof, of Hi-Lo and each of its Subsidiaries.
Neither Hi-Lo nor any of its Subsidiaries is in violation of any of the
provisions of its respective Certificate or Articles of Incorporation, By-laws,
Certificate of Limited Partnership, or Limited Partnership Agreement.

     (a) Hi-Lo does not own, directly or indirectly, any equity or other
ownership interest in any corporation, partnership, joint venture or other
entity or enterprise, except for the Subsidiaries.  Hi-Lo is not subject to any
corporate or contractual obligation or requirement to make any investment, loan
or capital contribution to any corporation, partnership, joint venture or other
entity or enterprise, other than its Subsidiaries.  Each of Hi-Lo's
Subsidiaries is duly organized, validly existing and in good standing under the
laws of its jurisdiction of incorporation or organization, has the corporate
and/or partnership power and authority to own its properties and to carry on its
business as it is now being conducted, and is duly qualified to do business and
is in good standing in each jurisdiction in which the ownership of its property
or the conduct of its business requires such qualification, except for
jurisdictions in which such failure to be so qualified or to be in good

                                      18
<PAGE>
 
standing would not, individually or in the aggregate, have a Material Adverse
Effect on Hi-Lo.  All the outstanding shares of capital stock of, or other
ownership interests in, Hi-Lo's Subsidiaries are validly issued, fully paid and
non-assessable and are owned by Hi-Lo, directly or indirectly, free and clear of
all liens, claims, charges or encumbrances, except such as are contained in
credit agreements and similar instruments to which Hi-Lo is a party under
which no event of default exists and no event has occurred which with the giving
of notice or passage of time would constitute an event of default thereunder.
There are no existing subscriptions, options, warrants, rights of first refusal,
preemptive rights, calls, commitments, agreements or conversion rights of any
character relating to the issued or unissued capital stock or other securities
of, or other ownership interests in, any Subsidiary of Hi-Lo.

     Section 4.2  Capital Stock.  The authorized stock of Hi-Lo consists of
30,000,000 shares of common stock, par value $.01 per share ("Hi-Lo Common
Stock"), and 5,000,000 shares of preferred stock, par value $.01 per share ("Hi-
Lo Preferred Stock"), of which 50,000 shares have been designated as Series A
Junior Participating Preferred Stock ("Hi-Lo Series A Preferred Stock").  As of
December 15, 1997, 10,775,109 shares of Hi-Lo Common Stock and no shares of Hi-
Lo Preferred Stock were issued and outstanding.  All the outstanding shares of
Hi-Lo Common Stock have been validly issued and are fully paid and non-
assessable and have not been issued in violation of any preemptive or similar
rights.  As of December 15, 1997, there were no outstanding subscriptions,
options, warrants, rights or other arrangements or commitments obligating Hi-Lo
to issue any shares of its capital stock nor are there outstanding any
securities which are convertible into or exchangeable for any shares of capital
stock of Hi-Lo, and Hi-Lo has no obligations of any kind to issue any additional
securities other than:

          (i)  rights to acquire shares of Hi-Lo Series A Preferred Stock
     pursuant to the Rights Agreement; and

          (ii)  options and other rights to receive or acquire not in excess of
     1,094,789 shares of Hi-Lo Common Stock granted on or prior to November 30,
     1997, pursuant to employee incentive or benefit plans, programs and
     arrangements and non-employee director plans.

     (a) Except for the issuance of shares of Hi-Lo Common Stock pursuant to the
options and other rights referred to in Section 4.2(a)(i) and except as
permitted in Section 6.1(i) and (j), since September 30, 1997, no shares of Hi-
Lo Common Stock or Hi-Lo Preferred Stock have been issued.

                                      19
<PAGE>
 
     (b) Except as disclosed in the letter so designated and executed by Hi-Lo
dated the date hereof and delivered to O'Reilly on the date hereof ("Hi-Lo's
Disclosure Letter") the issuance and sale of all of the outstanding shares of
capital stock described in Section 4.2 have been in compliance with federal and
state securities laws.  Except pursuant to the terms of that certain
Shareholder's Agreement, dated October 7, 1987, as amended, Hi-Lo has not
agreed to register any securities under the Securities Act of 1933, as amended
(the "Securities Act") or under any state securities law or granted registration
rights to any persons or entity. Except as disclosed in Hi-Lo's Disclosure
Letter, there are no outstanding obligations of Hi-Lo or any of Hi-Lo's
Subsidiaries to repurchase, redeem or otherwise acquire any shares of capital
stock of Hi-Lo and no person has any right to cause Hi-Lo or any of its
Subsidiaries to repurchase, redeem or otherwise acquire any shares of capital
stock of Hi-Lo.

     Section 4.3  Corporate Authority Relative to this Agreement; No Violation;
No Conflict.  Hi-Lo has the corporate power and authority necessary to enter
into this Agreement and to carry out its obligations hereunder.  The execution
and delivery of this Agreement and the consummation of the transactions
contemplated hereby have been duly and validly authorized by the Board of
Directors of Hi-Lo and, except, with respect to the Merger, for the approval of
its stockholders, no other corporate proceedings on the part of Hi-Lo are
necessary to authorize this Agreement and the transactions contemplated hereby.
This Agreement has been duly and validly executed and delivered by Hi-Lo and,
assuming this Agreement constitutes a valid and binding Agreement of the other
parties hereto, this Agreement constitutes a valid and binding agreement of Hi-
Lo, enforceable against Hi-Lo in accordance with its terms (except insofar as
enforceability may be limited by applicable bankruptcy, insolvency,
reorganization, moratorium or other laws affect ing creditors' rights generally,
or by principles governing the availability of equitable remedies). Other than
in connection with or in compliance with the provisions of the DGCL (including
the approval of the Merger by the stockholders of Hi-Lo), the Exchange Act, the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the "HSR Act")
(collectively, the "Hi-Lo Required Approvals"), no authorization, consent or
approval of, or filing by Hi-Lo with, any governmental body or authority or
other person is necessary for the execution and delivery of this Agreement or
for the consummation by Hi-Lo of the transactions contemplated by this Agreement
except where the failure to obtain such authorizations, consents or approvals or
make such filings is not reasonably likely to have a Material Adverse Effect on
Hi-Lo. Except as disclosed in Hi-Lo's Disclosure Letter, neither the execution
and delivery of this Agreement by Hi-Lo nor the consummation by Hi-Lo

Material Adverse Effect on Hi-Lo.

     (a) All of the Annual Reports, Quarterly Reports, Current Reports, Hi-Lo
Proxy Statements and prospectuses filed with the SEC since December 31, 1994
(collectively, the "Hi-Lo SEC Reports") at the time filed (and in the case of

respects with the applicable requirements of the Securities Act, the Exchange
Act and the rules and regulations promulgated thereunder and (ii) did not
contain any untrue statement of a material fact or omit to state a material fact
required to be stated therein or necessary to make the statements therein, in

where appropriate, to normal year-end adjustments), in each case in accordance
with past practice and generally accepted accounting principles in the United
States ("GAAP") consistently applied during the periods involved (except as
otherwise disclosed in the notes thereto or in the case of unaudited statements,
as permitted by the rules of the SEC or Form 10-Q).  Since December 31, 1994,
Hi-Lo has timely filed all material reports, registration statements and other

Securities Act and the rules and regulations of the SEC.

     (b) The minute books of Hi-Lo and each of Hi-Lo's corporate Subsidiaries
contain accurate records of all meetings held of, and corporate action taken by,

any such stockholders or Board of Directors has been held for which minutes have
not been prepared and are not contained in such minute books except as disclosed
in Hi-Lo's Disclosure Letter.

     Section 4.5  No Undisclosed Liabilities.  As of the date hereof neither Hi-
Lo nor any of its Subsidiaries has any liabilities or obligations of any nature,
whether or not accrued, contingent or otherwise, that would be required by GAAP

obligations (a) reflected in any of the Hi-Lo SEC Reports filed prior to the
date of this Agreement, (b) incurred in the ordinary course of business since
December 31, 1996, or (c) liabilities or obligations which are not reasonably

hereinafter defined)) except (a) as described in any of the Hi-Lo SEC Reports
filed prior to the date of this Agreement and (b) for violations or possible
violations which are not reasonably likely, individually or in the aggregate, to
have a Material Adverse Effect on Hi-Lo.

     Section 4.7  Environmental Laws and Regulations.  Except as described in
any of the Hi-Lo SEC Reports filed prior to the date of this Agreement or in
Section 4.7 of Hi-Lo's Disclosure Letter, as of the date hereof (a) Hi-Lo and
each of its Subsidiaries is in compliance with all applicable federal, state,
local and foreign laws and regulations relating to pollution or protection of
human health or the environment (including, without limitation, ambient air,
surface water, ground water, land surface or subsurface strata) (collectively,
"Environmental Laws"), except for non-compliance which are not reasonably
likely, individually or in the aggregate, to have a Material Adverse Effect on
Hi-Lo, which compliance includes, but is not limited to, the possession by Hi-Lo
and its Subsidiaries of material permits and other governmental authorizations
required under applicable Environmental Laws, and compliance with the terms and
conditions thereof; (b) neither Hi-Lo nor any of its Subsidiaries has received
written notice of, or, to the knowledge of Hi-Lo, is the subject of, any
actions, causes of action, claims, investigations, demands or notices by any
person alleging liability under or non-compliance with any Environmental Law
("Environmental Claims") which are reasonably likely, individually or in the
aggregate, to have a Material Adverse Effect on Hi-Lo; and (c) to the knowledge
of Hi-Lo, there are no circumstances that are reasonably likely to prevent or
interfere with such compliance in the future.  Except as set forth in Section
4.7 of Hi-Lo's Disclosure Letter, to the knowledge of Hi-Lo, there are no past
or present actions or activities, including, without limitation, the release,
emission, discharge or disposal of any Hazardous Material at any site presently
owned by Hi-Lo or its Subsidiaries in the conduct of their business, that could
form the basis of any claim against Hi-Lo or its Subsidiaries under
Environmental Laws, which claims, individually or in the aggregate, could
reasonably be expected to have a Material Adverse Effect on Hi-Lo. For purposes
of this Section 4.7, "Hazardous Material" means chemicals, pollutants,
contaminants, wastes, toxic substances, hazardous substances, petroleum or
petroleum products and any other substance or material regulated as toxic or
hazardous pursuant to Environmental Law.

     Section 4.8  Employee Matters; ERISA.  Set forth in Hi-Lo's Disclosure
Letter is a true and complete list of all material employee benefit plans
maintained or contributed to as of the date hereof by Hi-Lo or any of its
Subsidiaries covering their present and former employees or directors or their
beneficiaries, or providing benefits to such persons in respect of services
provided to any such entity, including, but not limited to, any employee benefit
plans within the meaning of Section 3(3) of the Employee Retirement Income
Security Act of 1974, as amended ("ERISA"), any deferred compensation, bonuses,
stock options, restricted stock plans, incentive compensation, severance or
change in control agreements and any

                                      23
<PAGE>
 
other material benefit arrangements or payroll practices (collectively, the "Hi-
Lo Benefit Plans").

     (a) Except for contributions and other payments that are not reasonably
likely, individually or in the aggregate, to have a Material Adverse Effect on
Hi-Lo, all contributions and other payments required to be made by Hi-Lo or any
of its Subsidiaries to or under any Hi-Lo Benefit Plan (or to any person
pursuant to the terms thereof) have been made or the amount of such payment or
contribution obligation has been reflected in the Hi-Lo SEC Reports.

     (b) Each of the Hi-Lo Benefit Plans intended to be "qualified" within the
meaning of Section 401(a) of the Code has received a favor  able determination
letter from the Internal Revenue Service (the "IRS") as to such qualified
status.

     (c) Except as described in any of the Hi-Lo SEC Reports filed prior to the
date of this Agreement, all Hi-Lo Benefit Plans are in compliance with all
applicable provisions of ERISA and the Code, and Hi-Lo and its Subsidiaries do
not have any liabilities or obligations with respect to any Hi-Lo Benefit Plan,
whether or not accrued, contingent or otherwise, except (i) as described in any
of the Hi-Lo SEC Reports or disclosed in writing to O'Reilly in Hi-Lo's
Disclosure Letter and (ii) for instances of non-compliance or liabilities or
obligations that are not reasonably likely, individually or in the aggregate, to
have a Material Adverse Effect on the Hi-Lo.

     (d) With respect to Hi-Lo Benefit Plans, individually and in the aggregate,
no event has occurred and, to Hi-Lo's knowledge, there does not now exist any
condition or set of circumstances that could subject Hi-Lo or any of its
Subsidiaries to any material liability arising under ERISA or the Code
(including, without limitation, any liability to any such plan or the Pension
Benefit Guaranty Corporation (the "PBGC")), or under any indemnity agreement to
which Hi-Lo or any of its Subsidiaries is a party, excluding (1) liability for
benefit claims and funding obligations payable in the ordinary course and (2)
liabilities that are not reasonably likely, individually or in the aggregate, to
have a Material Adverse Effect on Hi-Lo.

                                      24
<PAGE>
 
     (e) Except as disclosed in writing to O'Reilly in Hi-Lo's Disclosure
Letter, none of the Hi-Lo Benefit Plans that are "welfare plans" within the
meaning of Section 3(1) of ERISA provides for any retiree benefits other than
continuation coverage required to be provided under Section 4980B of the Code or
Part 6 of Title I of ERISA.

     (f) Except (i) as contemplated in this Agreement, (ii) as provided in the
termination benefit agreements listed and identified as such in Hi-Lo's
Disclosure Letter which are in effect on the date hereof (the "Change of Control
Employment Agreements"), (iii) as described in any of the Hi-Lo SEC Reports or
(iv) as disclosed in writing to O'Reilly in Hi-Lo's Disclosure Letter, the
consummation or announcement of any transaction contemplated by this Agreement
will not (whether alone or upon the occurrence of any additional or further acts
or events) result in any (A) payment (whether of severance pay or otherwise)
becoming due from Hi-Lo or any of its Subsidiaries to any officer, employee,
former employee or director thereof or to the trustee under any "rabbi trust" or
similar arrangement, or (B) benefit under any Hi-Lo Benefit Plan being
established or becoming accelerated, vested or payable.  Except as disclosed in
Hi-Lo's Disclosure Letter or as described in any of the Hi-Lo SEC Reports,
neither Hi-Lo nor any of its Subsidiaries is a party to (A) any management,
employment, deferred compensation, severance (including any payment, right or
benefit resulting from a change in control), bonus or other contract for
personal services with any current or former officer, director or employee
(whether or not characterized as a plan for purposes of ERISA), (B) any material
consulting contract with any person who prior to entering into such contract was
a director or officer of Hi-Lo or any of its Subsidiaries, or (C) any plan,
agreement, arrangement or understanding similar to any of the items described in
clause (A) or (B) of this sentence.

     (g) The consummation or announcement of any transaction contemplated by
this Agreement will not (either alone or upon the occurrence of any additional
or further acts or events) result in the disqualification of any of the Hi-Lo
Benefit Plans intended to be qualified under, result in a prohibited transaction
or breach of fiduciary duty under, or otherwise violate, ERISA or the Code.

     (h) Neither Hi-Lo nor any of its Subsidiaries nor any of their directors,
officers, employees or agents, nor any "party in interest" or "disqualified
person," as such terms are defined in Section 3 of ERISA and Section 4975 of the
Code has, with respect to any Hi-Lo Benefit Plan, engaged in or been a party to
any "prohibited transaction," as such term is defined in Section 4975 of the
Code or Section 406 of ERISA which is not otherwise exempt, which could result
in the

                                      25
<PAGE>
 
imposition of either a penalty assessed pursuant to Section 502(i) of ERISA or a
tax imposed by Section 4975 of the Code or which could constitute a breach of
fiduciary duty, in each case applicable to Hi-Lo and which is reasonably likely
to have a Material Adverse Effect on Hi-Lo.

     (i)  No Hi-Lo Benefit Plan subject to Section 412 of the Code has incurred
any now existing "accumulated funding deficiency" (as defined in ERISA), whether
or not waived. Neither Hi-Lo nor any of its Subsidiaries has incurred, and none
of such entities reasonably expects to incur, any material liability to the PBGC
with respect to any Hi-Lo Benefit Plan. Neither Hi-Lo nor any of its
Subsidiaries is a party to, and neither has incurred or reasonably expects to
incur, any withdrawal liability with respect to any "multiemployer plan" (as
defined in Section 3(37) of ERISA) for which there is any outstanding liability.

     (j)  None of the assets of any of Hi-Lo Benefit Plans which hold assets are
invested in securities of Hi-Lo.

     (k)  Hi-Lo is in material compliance with the notice provisions and all
other provisions of COBRA and the Health Insurance Portability and
Accountability Act of 1996, except for instances of non-compliance that are not
reasonably likely, individually or in the aggregate, to have a Material Adverse
Effect on Hi-Lo.

     (l)  Except as disclosed in writing to O'Reilly in Hi-Lo's Disclosure
Letter or as described in any of the Hi-Lo SEC Reports, since December 31, 1996,
no change has occurred in the base salary of any person who is a party to a
Change of Control Employment Agreement.

     Section 4.9 Absence of Certain Changes or Events. Except as disclosed in
the Hi-Lo SEC Reports filed prior to the date of this Agreement or in Hi-Lo's
Disclosure Letter, from December 31, 1996 to the date of this Agreement, the
businesses of Hi-Lo and its Subsidiaries have been conducted in all material
respects in the ordinary course and there has not been any event, occurrence,
development or state of circumstances or facts that has had or is reasonably
likely to have a Material Adverse Effect on Hi-Lo. Since December 31, 1996,
neither Hi-Lo nor any of its Subsidiaries has engaged in any transaction which,
if done after the execution of this Agreement, would violate Sections 6.1(e)
through (k), 6.1(n) through (q), or 6.1(s) through (u) hereof, except as
disclosed in Hi-Lo's SEC Reports filed prior to the date of this Agreement or
disclosed in Hi-Lo's Disclosure Letter.

this Agreement or disclosed in Hi-Lo's Disclosure Letter:

     (a)  no investigation or review by any governmental body or authority with
respect to Hi-Lo or any of its Subsidiaries is pending nor has any governmental
body or authority notified Hi-Lo in writing of an intention to conduct the same
and, to the knowledge of Hi-Lo no such investigation or review has been
threatened in each case which is reasonably likely, individually or in the
aggregate, to have a Material Adverse Effect on Hi-Lo; and

     (b)  there are no actions, suits or proceedings pending (or, to Hi-Lo's
knowledge, threatened) against or affecting Hi-Lo or its Subsidiaries, or any of
their respective properties at law or in equity, or before any federal, state,
local or foreign governmental body or authority, which, individually or in the
aggregate, are reasonably likely to have a Material Adverse Effect on Hi-Lo.

     Section 4.11 Proxy Statement; Offer Documents; Schedule 14D-9; Proxy
Statement. None of the Schedule 14D-9, any information supplied in writing by 
Hi-Lo specifically for inclusion in the Offer Documents or the information to be
filed by Hi-Lo in connection with the Offer pursuant to Rule 14f-1 promulgated
under the Exchange Act (the "Information Statement"), shall at the respective
times the Schedule 14D-9, the Offer Documents, the Information Statement or any
amendments or supplements thereto are filed with the SEC or are first published,
sent or given to stockholders of Hi-Lo, as the case may be, 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 made therein, in the
light of the circumstances under which they are made, not misleading. The Proxy
Statement and the Information Statement shall not, at the date such document (or
any amendment or supplement thereto) is first mailed to stockholders of Hi-Lo,
with respect to the Information Statement at the time Shares are accepted for
payment in the Offer, and with respect to the Proxy Statement at the time of the
Stockholders' Meeting, be false or misleading with respect to any material fact,
or omit to state any material fact required to be stated therein or necessary in
order to make the statements made therein in the light of the circumstances
under which they are made, not misleading. The Schedule 14D-9, the Information
Statement and the Proxy Statement shall comply in all material respects as to
form with the applicable requirements of the Exchange Act and the applicable
rules and regulations thereunder. Notwithstanding the foregoing, Hi-Lo makes no
representation or warranty with respect to statements


                                      27
<PAGE>
 
made in any of the foregoing documents based on information supplied in writing
by O'Reilly or Sub or any of their representatives specifically for inclusion
therein.

     Section 4.12 Hi-Lo Rights. Hi-Lo has taken all action which may be
necessary to amend the Rights Agreement, so that the execution of this Agreement
and any amendments thereto by the parties hereto and the consummation of the
transactions contemplated hereby or thereby shall not cause (i) O'Reilly or Sub
to become an Acquiring Person (as defined in the Rights Agreement) or (ii) a
Distribu tion, or a Shares Acquisition Date (as each such term is defined in the
Rights Agreement) to occur, irrespective of the number of Shares acquired
pursuant to the Offer.

     Section 4.13 Takeover Laws. Prior to the date hereof, the Board of
Directors of Hi-Lo has taken all necessary action to exempt under or make not

stock, the execution of this Agreement and the consummation of the transactions
contemplated hereby, including the Offer and the Merger.

     Section 4.14 Tax Matters. (a) Except for matters that are not reason ably
likely to have a Material Adverse Effect on Hi-Lo or are disclosed in Hi-Lo's
Disclosure Letter: (i) all Tax Returns, which are required to be filed on or

or any of its Subsidiaries; (v) neither Hi-Lo nor any of its Subsidiaries has
any liability for any Taxes in excess of amounts paid or reserves established

the due date for the filing of any Hi-Lo Tax Return or any waiver or agreement
for any extension of time for the assessment or payment of any tax due with

waivers or agreements are pending. Except as disclosed in Hi-Lo's Disclosure
Letter, neither Hi-Lo nor any of its Subsidiaries is the subject of any
currently ongoing tax audit which is reasonably likely to have a Material
Adverse Effect on Hi-Lo. With respect to any taxable period ended prior to

the applicable statute of limitations.

     (b)  There are no material liens with respect to Taxes upon any of the
properties or assets, real or personal, tangible or intangible of Hi-Lo or any
of its Subsidiaries (other than liens with respect to Taxes not yet due). No
material claim made in writing by an authority in a jurisdiction where none of
Hi-Lo or its Subsidiaries files tax returns that Hi-Lo or any of its
Subsidiaries is or may be subject to taxation by that jurisdiction is currently
pending. Hi-Lo has not filed an election under Section 341(f) of the Internal
Revenue Code to be treated as a consenting corporation. Neither Hi-Lo nor any of
its Subsidiaries is obligated by any contract, agreement or other arrangement to
indemnify any other person with respect to any material Taxes.

     (c)  Except for matters that are disclosed in Hi-Lo's Disclosure Letter:
none of Hi-Lo or any of its Subsidiaries is a party to any agreement, contract,
arrangement or plan that has resulted or would result, separately or in the
aggregate, in the payment of (x) any "excess parachute payments" within the
meaning of Section 280G of the Code (without regard to the exceptions set forth
in Section 280G(b)(4) and 280G(b)(5) of the Code) or (y) any amount for which a
deduction would be disallowed under Section 162 of the Code; since January 1,
1993, none of Hi-Lo or any of its Subsidiaries has been a member of a group
filing a consolidated federal income Tax Return (other than a group the common
parent of which was Hi-Lo); no liability has been asserted with respect to Hi-Lo
or any of its Subsidiaries for the Taxes of any Person (other than any of Hi-Lo
or its Subsidiaries) under Treasury Regulation Section 1.1502-6 (or any
corresponding provision of state, local or foreign Tax law), as a transferee or
successor, by contract, or otherwise; and none of Hi-Lo or any of its
Subsidiaries has net operating losses or other tax attributes presently subject
(without regard to the transactions contemplated by this Agreement) to

consolidated return regulations.

     (d)  For purposes of this Agreement: (i) "Taxes" means any and all federal,
state, local, foreign or other taxes of any kind (together with any and all

<PAGE>
 
in the nature of excise, withholding, customs duties, ad valorem or value added,
and (ii) "Tax Return" means any return, report or similar statement (including
the attached schedules) filed or required to be filed with respect to any Tax,
including, without limitation, any information return, claim for refund or

     Section 4.15 Opinion of Financial Advisor. The Board of Directors of Hi-Lo
has received the opinion of SBC Warburg Dillon Read Inc., dated the date of this
Agreement, to the effect that, as of such date, the cash consideration to be
received by Hi-Lo's stockholders pursuant to the Offer and the Merger is fair to
such stockholders from a financial point of view. A copy of the written opinion
of SBC Warburg Dillon Read Inc. has been delivered to O'Reilly.

     Section 4.16 Required Vote of Hi-Lo Stockholders. The affirmative vote of
the holders of a majority of the outstanding shares of Hi-Lo Common Stock is

Agreement and the transactions contemplated hereby.

     Section 4.17 Labor Matters. No labor organization or group of employees of
Hi-Lo or any of its Subsidiaries has made a pending demand for recognition or
certification, and there are no representation or certification proceedings or
petitions seeking a representation proceeding presently pending or to the
knowledge of Hi-Lo threatened to be brought or filed, with the National Labor
Relations Board or any other labor relations tribunal or authority except for
demands, proceedings or petitions which are not reasonably likely to have a
Material Adverse Effect on Hi-Lo. There are no strikes, work stoppages,
lockouts, material arbitrations or material grievances, or other material labor
disputes pending or to the knowledge of Hi-Lo threatened against or involving 
Hi-Lo or any of its Subsidiaries except such as are not reasonably likely to
have a Material Adverse Effect on Hi-Lo. None of Hi-Lo or any of its
Subsidiaries is a party to or bound by any collective bargaining or similar
agreement with any labor organization.

     Section 4.18 Certain Agreements. Except as disclosed in Hi-Lo's Disclosure
Letter or in the Hi-Lo SEC Reports filed prior to the date of this Agreement,
neither Hi-Lo nor any of its Subsidiaries is a party or subject to any oral or
written agreement, contract, policy, license, document, instrument, arrangement
or commitment relating to or constituting (i) Indebtedness (as hereinafter
defined) in an amount exceeding $500,000 other than pursuant to Hi-Lo's
revolving credit facility with the CIT Group which would in no event cause the
aggregate amount outstanding


                                      30
<PAGE>
 
under such facility to exceed $60,000,000, (ii) leases for real or personal
property in which the amounts of payments which Hi-Lo or any Subsidiary is
required to make on an annual basis exceeds $250,000, (iii) agreement, contract,
policy, license document, instrument, arrangement or commitment that limits in
any material respect the freedom of Hi-Lo or any Subsidiary of Hi-Lo to compete
in any line of business or with any person or in any geographical area or which
would so limit the freedom of Hi-Lo or any Subsidiary of Hi-Lo after the
Effective Time, (iv) agreement or contract outside of the ordinary course of
business of Hi-Lo or any of Hi-Lo's Subsidiaries that involves performance of
services or delivery of goods or materials by or to Hi-Lo or any of Hi-Lo's
Subsidiaries of an amount or value in excess of $250,000, (v) joint venture or
partnership agreements involving a sharing of profits, losses, costs, or
liabilities by Hi-Lo or any of Hi-Lo's Subsidiaries with any person other than
Hi-Lo and its Subsidiaries, (vi) power of attorney granted by Hi-Lo or any of 
Hi-Lo's Subsidiaries that is currently effective and outstanding, (vii)

that contains or provides for an express undertaking by Hi-Lo or any of Hi-Lo's
Subsidiaries to be responsible for consequential damages, (viii) agreement or
contract for capital expenditures in excess of $200,000, (ix) a written
warranty, guaranty, and/or other similar undertaking with respect to contractual
performance extended by Hi-Lo or any of Hi-Lo's Subsidiaries other than in the
ordinary course of business, or (x) which, after giving effect to the
transactions contemplated by this Agreement, purports to restrict or bind
O'Reilly or any of its Subsidiaries other than the Surviving Corporation and its
Subsidiaries in any respect. "Indebtedness" means any liability in respect of
(A) borrowed money, (B) capitalized lease obligations, (C) the deferred purchase
price of property or services (other than trade payables in the ordinary course
of business) and (D) guarantees of any of the foregoing. Except as disclosed in
Hi-Lo's Disclosure Letter, neither Hi-Lo nor any of its Subsidiaries is in
default (or would be in default with notice or lapse of time, or both) under any
indenture, note, credit agreement, loan document, lease, contract, policy,
license, document, instrument, arrangement or commitment, whether or not such
default has been waived, which default, alone or in the aggregate with other
such defaults, is reasonably likely to have a Material Adverse Effect on Hi-Lo.

     Section 4.19 Title to Assets; Liens. Hi-Lo owns or holds through valid
leases, directly or through its Subsidiaries, all of its inventory, accounts
receivable, property, equipment and other assets except where the failure to own
or hold such property is not reasonably likely to have a Material Adverse Effect
on Hi-Lo, and except as disclosed in Hi-Lo's SEC Reports filed prior to the date
of this Agreement, such assets are free and clear of any mortgages, liens,
charges, encumbrances, or title defects of any nature whatsoever, except for
such mortgages, liens,


                                      31
<PAGE>
 
charges, encumbrances or title defects which are not reasonably likely to
adversely affect the value of such property as carried on Hi-Lo's financial
statements contained in Hi-Lo's SEC Reports filed prior to the date of this
Agreement and would not have a Material Adverse Effect on Hi-Lo. Hi-Lo and its
Subsidiaries have valid and enforceable leases for the premises and the
equipment, furniture and fixtures purported to be leased by them, except for
leases, the failure of which to have or be enforceable, are not reasonably
likely to have a Material Adverse Effect on Hi-Lo.

     Section 4.20 Insurance. Except as disclosed in Hi-Lo's Disclosure Letter,
Hi-Lo and each of its Subsidiaries are insured, and during each of the past five
calendar years have been insured with insurers whose current rating by A M Best
is at least B+6 against such risks and in such amounts as companies engaged in a
similar business would, in accordance with good business practice, customarily
be insured. Except as disclosed in Hi-Lo's Disclosure Letter, the policies of
fire, theft, liability and other insurance maintained with respect to the assets
or businesses of Hi-Lo and its Subsidiaries (copies of which have been made
available to O'Reilly) (i) provide coverage which Hi-Lo deems to be adequate
coverage against loss, (ii) are sufficient for Hi-Lo and its Subsidiaries to be
in compliance with all legal requirements applicable to Hi-Lo or any of its
Subsidiaries and all agreements and contracts to which Hi-Lo or any of its
Subsidiaries is a party or by which any of them are bound, except where such
insufficiency is not reasonably likely, individually or in the aggregate, to
have a Material Adverse Effect on Hi-Lo, (iii) will continue (absent affirmative
action by O'Reilly to cancel such policies) in full force and effect following
consummation of the Merger and (iv) do not provide for any retrospective premium
adjustment or other experienced-based liability on the part of Hi-Lo or any of
Hi-Lo's Subsidiaries. Except as disclosed in Hi-Lo's Disclosure Letter, neither
Hi-Lo nor any of its Subsidiaries has received written notice of cancellation or
termination with respect to any material insurance policy of Hi-Lo or its
Subsidiaries or will not be renewed or that the issuer of any material insurance
policy is not willing or able to perform its obligations thereunder. The
insurance policies of Hi-Lo and its Subsidiaries are valid and enforceable
policies. Hi-Lo and Hi-Lo's Subsidiaries have paid all premiums due, and have
otherwise performed all of their respective material obligations, under each
material insurance policy and Hi-Lo and Hi-Lo's Subsidiaries have given notice
to the respective insurer of all material claims that may be insured by any
material insurance policy.

     Section 4.21 Intellectual Property. To Hi-Lo's knowledge, neither Hi-Lo nor
any of its Subsidiaries utilizes or has utilized any patent, trademark, trade
name, service mark, copyright, software, trade secret or know-how, except for
those which are owned, possessed or lawfully used by Hi-Lo or its Subsidiaries
in their


                                      32
<PAGE>
 
operations, and, to the knowledge of Hi-Lo, neither Hi-Lo nor any of its
Subsidiaries infringes upon or unlawfully or wrongfully uses any patent,
trademark, tradename, service mark, copyright or trade secret owned or validly
claimed by another, where such infringement or unlawful or wrongful use is
reasonably likely to have a Material Adverse Effect on Hi-Lo.

     Section 4.22  Significant Vendor Arrangements.  Except as set forth in a
list which is included as part of Hi-Lo's Disclosure Letter, as of the date of
this Agreement, neither Hi-Lo nor any of its Subsidiaries is a party to any
contract or arrangement with any supplier or vendor which represents a
commitment in excess of $300,000.  The list of such contracts and arrangements
which is included as part of Hi-Lo's Disclosure Letter accurately identifies
each such supplier or vendor and the significant terms concerning termination,
term of the agreement, and the amount of up-front vendors' allowances that would
need to be repaid upon early termination as of December 1, 1997.

     Section 4.23  Termination of Discount Agreement.  Hi-Lo has taken all
action necessary to terminate, and has terminated, the Agreement and Plan of
Merger among Discount Auto Parts, Inc., HLA Acquisition, Inc. and Hi-Lo dated as
of October 17, 1997 in accordance with the terms thereof and has paid the
$4,000,000 termination fee pursuant to Section 7.2(b) thereof.


                                   ARTICLE V

              REPRESENTATIONS AND WARRANTIES OF O'REILLY AND SUB

     O'Reilly and Sub jointly and severally represent and warrant to Hi-Lo that:

     Section 5.1  Organization, Qualification, Etc.  Each of O'Reilly and Sub
is a corporation duly organized, validly existing and of active status or in
good standing under the laws of its jurisdiction of organization and has the
corporate power and authority to own its properties and assets and to carry on
its business as it is now being conducted and is duly qualified to do business
and is of active status or in good standing in each jurisdiction in which the
ownership of its properties or the conduct of its business requires such
qualification, except for jurisdictions in which such failure to be so qualified
or to be in good standing would not, individually or in the aggregate, have a
Material Adverse Effect on O'Reilly.  The copies of O'Reilly's and Sub's
Certificate of Incorporation and By-laws which have been made available

                                      33
<PAGE>
 
to Hi-Lo are complete and correct and in full force and effect on the date
hereof. Neither O'Reilly nor Sub is in violation of any of the provisions of its
respective Articles or Certificate of Incorporation or By-laws.

     Section 5.2  Corporate Authority Relative to this Agreement; No Violation;
No Conflict.  Each of O'Reilly and Sub has the corporate power and authority
necessary to enter into this Agreement and to carry out its obligations
hereunder.  The execution and delivery of this Agreement and the consummation of
the transactions contemplated hereby have been duly and validly authorized by
the Boards of Directors of O'Reilly and Sub and no other corporate proceedings
on the part of O'Reilly or Sub are necessary to authorize this Agreement and the
transactions contemplated hereby.  This Agreement has been duly and validly
executed and delivered by O'Reilly and Sub and, assuming this Agreement
constitutes a valid and binding Agreement of the other parties hereto, this
Agreement constitutes a valid and binding agreement of O'Reilly and Sub,
enforceable against each of them in accordance with its terms (except insofar
as enforceability may be limited by applicable bankruptcy, insolvency,
reorganization, moratorium or other laws affecting creditors' rights generally,
or by principles governing the availability of equitable remedies). Other than
in connection with or in compliance with the provisions of the DGCL, the
Securities Act, the Exchange Act or the HSR Act (collectively, the "O'Reilly 
Required Approvals"), no authorization, consent or approval of, or filing by
O'Reilly or Sub with, any governmental body or authority or other person is
necessary for the execution and delivery of this Agreement or for the
consummation by O'Reilly or Sub of the transactions contemplated hereby except
where the failure to obtain such authorizations, consents or approvals or make
such filing is not reasonably likely to have a Material Adverse Effect on
O'Reilly.  Except as disclosed in O'Reilly's Disclosure Letter, neither the
execution and delivery of this Agreement by O'Reilly and Sub nor the
consummation by O'Reilly and Sub of the transactions contemplated by this
Agreement will (a) result in a breach or violation of the organizational
documents of O'Reilly or Sub or of any of O'Reilly's Subsidiaries, (b) result in
a breach or violation of any provision of, or constitute a default (or an event
which, with the giving of notice, the passage of time or otherwise, would
constitute a default), under, or entitle any party (with the giving of notice,
the passage of time or otherwise) to terminate, accelerate or modify, or result
in the creation of any lien, security interest, charge or encumbrance upon any
of the properties or assets of O'Reilly or Sub or any of O'Reilly's Subsidiaries
under, any of the terms, conditions or provisions of any note, bond, mortgage,
indenture, deed of trust, contract, agreement, lease or other instrument or
obligation to which O'Reilly or Sub or any of its O'Reilly's Subsidiaries is a
party, or (c) subject to the matters set forth in the preceding sentence
violate any order, writ, injunction, decree, statute, rule or regulation

                                      34
<PAGE>
 
applicable to O'Reilly or Sub or any of O'Reilly's Subsidiaries or any of their
respective properties or assets or (d) give any governmental body the right to
revoke, withdraw, suspend, cancel, terminate or modify any governmental
authorization held by O'Reilly or any of its Subsidiaries,  except for such
violations which would not in the aggregate have a Material Adverse Effect on
O'Reilly.

     Section 5.3  Financing.  O'Reilly has, or has commitments to obtain,
sufficient funds (through existing credit arrangements or otherwise) to (a) pay
the Per Share Amount pursuant to the Offer, (b) pay the Merger Consideration
pursuant to the Merger, (c) refinance such of Hi-Lo's existing indebtedness as
shall be necessary to consummate the Offer and the Merger and the financing
therefor and provide working capital prior to the Effective Time and (d) pay
related fees and expenses.

     Section 5.4  Offer Documents; Schedule 14D-9; Proxy Statement. None of the
Offer Documents nor any of the information supplied by O'Reilly or any of its
Subsidiaries in writing specifically for inclusion in the Schedule 14D-9 shall,
at the respective times the Offer Documents or the Schedule 14D-9 or any
amendments or supplements thereto are filed with the SEC or are first published,
sent or given to stockholders of Hi-Lo, as the case may be, 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 made therein, in the
light of the circumstances under which they are made, not misleading.  The
information supplied in writing by O'Reilly specifically for inclusion in the
Proxy Statement or Information Statement shall not, at the date such document
(or any amendment or supplement thereto) is first mailed to stockholders of 
Hi-Lo, with respect to the Information Statement at the time Shares are accepted
for payment in the Offer, and with respect to the Proxy Statement at the time of
the Stockholders' Meeting be false or misleading with respect to any material
fact, or omit to state any material fact required to be stated therein or
necessary in order to make the statements made therein in the light of the
circumstances under which they are made, not misleading.  Notwithstanding the
foregoing, O'Reilly and Sub make no representation or warranty with respect to
any of the foregoing documents based on information supplied by Hi-Lo or any of
its representatives.  The Offer Documents shall comply in all material respects
as to form with the applicable requirements of the Exchange Act and the
applicable rules and regulations thereunder.

     Section 5.5  Lack of Ownership of Shares.  Neither O'Reilly nor any of its
Subsidiaries owns any Shares or other securities convertible into Shares.

     Section 6.3 Obligations of O'Reilly and Sub.  Neither O'Reilly nor Sub or
any of their Subsidiaries shall take any action which would make any
representation or warranty contained in Article V hereof (except for

     Section 6.4  [Intentionally Omitted]

     Section 6.5  Employee Benefit Plans.  Simultaneously with the consummation
of the Offer, O'Reilly shall assume each Change of Control Employment Agreement
then in effect and all of Hi-Lo's rights and obligations under each such
agreement.

     (a) O'Reilly shall take all actions necessary or appropriate with respect
to employees employed by Hi-Lo or any of its Subsidiaries from and after the
purchase of any Shares pursuant to the Offer (a "Hi-Lo Employee") to either, at
the sole election of O'Reilly, (i) continue to participate from and after the
Closing Date in the employee benefit plans and programs maintained by Hi-Lo
immediately prior to the Closing Date other than the 1990 Stock Option Plan and
the 1991 Associate Stock Purchase Plan or (ii) permit Hi-Lo Employees to
immediately thereafter participate in the employee benefit plans or programs
maintained by O'Reilly or any of its Subsidiaries for their employees generally
(the "O'Reilly Plans") other than O'Reilly's stock option plans or any employee
stock purchase plan meeting the requirements of Section 423 of the Code;
provided, however, that, if Hi-Lo's group health plan is terminated or
discontinued, O'Reilly shall permit each Hi-Lo Employee and his or her eligible
dependents (including, without limitation, all such Hi-Lo Employee's dependents
covered by Hi-Lo's group health plan as of the time such coverage ceases) to be
covered under a O'Reilly Plan that (i) provides medical and dental benefits to
the Hi-Lo Employee and such eligible dependents effective immediately upon the
cessation of coverage of such individuals under Hi-Lo's group health plan, (ii)
credits such Hi-Lo Employee, for the year during which such coverage under such
O'Reilly Plan begins, with any deductibles and co-payment already incurred
during such year under Hi-Lo's group health plan, and (iii) waives any
preexisting condition restrictions to the extent necessary to provide immediate
coverage. O'Reilly, the Surviving Corporation, their respective Subsidiaries,
and the O'Reilly Plans shall recognize each Hi-Lo Employee's years of service
and level of seniority with Hi-Lo and its Subsidiaries for purposes of terms of
employment and eligibility, vesting and benefit determination under the O'Reilly
Plans. The provisions of this Section 6.5(b) shall be applicable only during an

                                      41
<PAGE>
 
employee's employment with Hi-Lo, O'Reilly or one of their Subsidiaries and
shall not constitute an agreement to employ or continue the employment of any
person.

     Section 6.6  Filings; Other Action.  Subject to the terms and conditions
herein provided, Hi-Lo and O'Reilly shall (a) as soon as practicable make their
respective filings and thereafter make any other required submissions under the
HSR Act, (b) use reasonable efforts to cooperate with one another in (i)
determining whether any filings are required to be made with, or consents,
permits, authorizations or approvals are required to be obtained from any third
party, governmental or regulatory bodies or authorities of federal, state and
local jurisdictions in connection with the execution and delivery of this
Agreement and the consummation of the transactions contemplated hereby and
thereby, and (ii) timely making all such filings and timely seeking all such
consents, permits, authorizations or approvals, and (c) use reasonable efforts
to take, or cause to be taken, all other actions and do, or cause to be done,
all other things necessary, proper or advisable to consummate and make effective
the transactions contemplated hereby, including, without limitation, taking all
such further action as reasonably may be necessary to resolve such objections,
if any, as the Federal Trade Commission, the Antitrust Division of the
Department of Justice, state antitrust enforcement authorities or any other
person may assert under relevant antitrust or competition laws with respect to
the transactions contemplated hereby.

     Section 6.7  Further Assurances.  Each of the Parties shall use its
reasonable best efforts to take all action and to do all things necessary,
proper or advisable to consummate the transactions contemplated by this
Agreement (including, without limitation, using its reasonable efforts to
cause the conditions to the consummation of the Offer set forth in Annex A
hereto and the conditions to the Merger set forth in Article VII for which they
are responsible to be satisfied as soon as reasonably practicable and to
prepare, execute and deliver such further instruments and take or cause to be
taken such other and further action as any other party hereto shall reasonably
request).

     Section 6.8  No Solicitation.  From the date hereof until the termination
of this Agreement, Hi-Lo will not, and shall not authorize or permit, any of its
officers, directors, employees, attorneys, financial advisors, agents or other
representatives or those of any of its Subsidiaries ("Hi-Lo's
Representatives") to, directly or indirectly, (a) solicit, initiate or knowingly
encourage any Takeover Proposal (as hereinafter defined), including without
limitation by disclosure of non-public information, or (b) engage in discussions
or negotiations relating to or accept any Takeover Proposal; provided, however,
that nothing contained in this Section 6.8

                                      42
<PAGE>
 
shall prohibit Hi-Lo and its Board of Directors from (i) taking and disclosing a
position with respect to a tender offer by a third party pursuant to Rules 14d-9
and 14e-2(a) promulgated by the SEC under the Exchange Act, or (ii) at any time
prior to the purchase of Shares pursuant to the Offer, engaging in discussions
or negotiations with, and furnishing information (including non-public
information) concerning Hi-Lo and its Subsidiaries, businesses, properties or
assets to, any third party which makes a Takeover Proposal (without any
solicitation or initiation or knowing encouragement, directly or indirectly, by
Hi-Lo or any of Hi-Lo's Representatives after the date of this Agreement) if the
Board of Directors of Hi-Lo determines in good faith, based on advice of its
outside counsel (who may be its regularly engaged outside counsel), that the
failure to take such action will violate its obligations or duties to Hi-Lo and
Hi-Lo's stockholders under applicable law, or (iii) provided this Agreement is
terminated pursuant to Section 8.1(d), accepting a Superior Proposal. Prior to
furnishing information to or entering into discussions or negotiations with any
person, Hi-Lo shall receive from such person or entity an executed
confidentiality agreement in reasonably customary form on terms not in the
aggregate materially more favorable to such person or entity than the terms
contained in Hi-Lo Confidentiality Agreement (as defined in Section 6.2 hereof)
unless the same terms are granted to O'Reilly under the Hi-Lo Confidentiality
Agreement. Hi-Lo shall immedi ately cease and cause to be terminated any
existing solicitation, initiation, encourage ment, activity, discussion or
negotiation with any person conducted heretofore by Hi-Lo or any Hi-Lo
Representative with respect to any Takeover Proposal existing on the date
hereof. Hi-Lo agrees not to release any third party from, or waive any provision
of, any standstill agreement to which it is a party or any confidentiality
agreement between it and another person who has made, or who may reasonably be
considered likely to make, or who was given access in order to consider making,
a Takeover Proposal, unless its Board of Directors determines in good faith,
based on advice of its outside counsel (who may be its regularly engaged outside
counsel), that failure to take such action will violate its obligations or
duties to Hi-Lo and Hi-Lo's stockholders under applicable law. Hi-Lo shall
notify O'Reilly orally and in writing of any such Takeover Proposal received
(including, without limitation, the terms and conditions of any such proposal
and the identity of the person making it), within 24 hours of the receipt
thereof, and shall keep O'Reilly informed of the general status and any material
changes in the terms and conditions of such Takeover Proposal. Hi-Lo agrees to
promptly provide to O'Reilly any information concerning Hi-Lo, its Subsidiaries,
business, properties or assets furnished to any third party which makes a
Takeover Proposal and which has not previously been provided to O'Reilly. As
used in this Agreement, (i) "Takeover Proposal" shall mean any written proposal
or offer, in each case made prior to the stockholder vote at Hi-Lo Meeting,
other than a proposal or offer by O'Reilly or any of its Subsidiaries, for a
tender offer, recapital-

                                      43
<PAGE>
 
ization, merger, consolidation or other business combination involving, or any
purchase of, all or substantially all of the assets or more than 50% of the
voting securities of, Hi-Lo, and (ii) "Superior Proposal" shall mean a bona fide
Takeover Proposal made by a third party on terms that a majority of the members
of the Board of Directors of Hi-Lo determines in their good faith reasonable
judgment is more favorable to Hi-Lo and to its stockholders than the
transactions contemplated hereby.

     Section 6.9  Public Announcements.  Hi-Lo and O'Reilly will consult with
each other before issuing any press release relating to this Agreement or the
transactions contemplated herein and shall not issue any such press release
prior to such consultation except as may be required by law or by obligations
pursuant to any listing agreement with any national securities exchange.

     Section 6.10  Indemnification and Insurance.  O'Reilly and Sub agree that
all rights to exculpation and indemnification for acts or omissions occurring
prior to the Effective Time now existing in favor of the current or former
directors or officers (the "Indemnified Parties") of Hi-Lo as provided in its
Certificate of Incorporation or by-laws or in any agreement, in each case as in
effect as of the date hereof, shall survive the Merger and shall continue in
full force and effect in accordance with their terms without amendment thereof.
For six years from the Effective Time, O'Reilly shall indemnify the Indemnified
Parties to the same extent as such Indemnified Parties are entitled to
indemnification pursuant to the preceding sentence.

     (a) For six years from the Effective Time, O'Reilly shall, maintain in
effect Hi-Lo's current directors' and officers' liability insurance covering
those persons who are currently covered by Hi-Lo's directors' and officers'
liability insurance policies and shall purchase such policy on or prior to the
Closing Date; provided, however, that in no event shall O'Reilly be required to
expend in the aggregate an amount in excess of 200% of the annual premiums
currently paid by Hi-Lo for such insurance, and, provided, further, that if the
aggregate premiums of such insurance coverage exceed such amount, O'Reilly shall
be obligated to obtain a policy with the greatest coverage available for a cost
not exceeding such amount.

     Section 6.11  Additional Reports.  Hi-Lo shall furnish to O'Reilly copies
of any reports of the type referred to in Section 4.4 which it files with the
SEC on or after the date hereof, and Hi-Lo represents and warrants that as of
the respective dates thereof, such reports will not contain any untrue statement
of a material fact or omit to state a material fact required to be stated
therein or necessary to make the statement therein, in light of the
circumstances under which they were made, not misleading. Any unaudited
consolidated interim financial statements included in

                                      44
<PAGE>
 
such reports (including any related notes and schedules) will fairly present the
financial position of Hi-Lo and its consolidated Subsidiaries as of the dates
thereof and the results of operations and changes in financial position or other
information included therein for the periods or as of the date then ended
(subject, where appropriate, to normal year-end adjustments), in each case in
accordance with past practice and GAAP consistently applied during the periods
involved (except as otherwise disclosed in the notes thereto).

     Section 6.12  [Intentionally Omitted]

     Section 6.13  [Intentionally Omitted]

     Section 6.14 Amendments to Change of Control Agreements. Hi-Lo has secured
a commitment to amend from each employee who is a party to a Change of Control
Employment Agreement and shall cause to be amended each Change of Control
Employment Agreement to provide that it shall be a condition to the receipt of
any lump sum payment payable thereunder that the employee execute and deliver to
Hi-Lo a general release by the employee of all claims against Hi-Lo, its
predecessors, parents, subsidiaries, divisions, related or affiliated
companies, officers, directors, stockholders, members, employees, heirs,
successors, assigns, representatives, agents and counsel, including without
limitation a release of (i) any and all claims arising out of or relating to the
employee's employment by or service with Hi-Lo and its Subsidiaries and the
employee's termination of employment, (ii) any and all claims of discrimination,
including but not limited to claims of discrimination on the basis of sex, race,
age, national origin, marital status, religion or handicap, including,
specifically, but without limiting the generality of the foregoing, any claims
under the Age Discrimination in Employment Act, as amended, Title VII of the
Civil Rights Act of 1964, as amended, and the Americans with Disabilities Act,
and (iii) any and all claims of wrongful or unjust discharge or breach of any
contract or promise, express or implied, provided that such release shall not
release claims of such person under the Change of Control Agreements or pursuant
to any indemnification rights or under any directors and officers insurance
policies.

     Section 6.15 Notifications. Between the date of this Agreement and the
Closing Date, Hi-Lo will promptly notify O'Reilly in writing if Hi-Lo becomes
aware that any of Hi-Lo's representations and warranties were materially untrue
as of the date of this Agreement or if Hi-Lo shall become aware of any fact or
condition that causes any of Hi-Lo's representations or warranties to be
materially untrue as of such date as if made on and as of such date (except for
representations and warranties made as of a specified date, which need be true
only as of such specified date).


                                      45
<PAGE>
 
During the same period, Hi-Lo will promptly notify O'Reilly of the occurrence of
any material breach of any covenant of Hi-Lo in this Article VI or of the
occurrence of any event that may make the satisfaction of the conditions in
Annex A hereto or Article VII impossible or unlikely.

     (a)  Between the date of this Agreement and the Closing Date, O'Reilly will
promptly notify Hi-Lo in writing if O'Reilly becomes aware that any of
O'Reilly's representations and warranties were materially untrue as of the date
of this Agreement or if O'Reilly shall become aware of any fact or condition
that causes any of O'Reilly's representations or warranties to be materially
untrue as of such date as if made on and as of such date (except for
representations and warranties made as of a specified date, which need be true
only as of such specified date). During the same period, O'Reilly will promptly
notify Hi-Lo of the occurrence of any material breach of any covenant of
O'Reilly in this Article VI or of the occurrence of any event that may make the
satisfaction of the conditions in Annex A hereto or Article VII impossible or
unlikely.

     Section 6.16 Indemnifications. Neither O'Reilly nor any of its Subsidiaries
or any of their respective officers, directors or employees shall be liable to
Hi-Lo or any of its Subsidiaries for any losses, claims, damages or liabilities
suffered as a result of any actions taken or any omission to take action by Hi-
Lo at the request of O'Reilly or its affiliates provided such request is not
made with willful intent to cause harm to Hi-Lo or its Subsidiaries. Hi-Lo
agrees to indemnify and hold harmless O'Reilly, its subsidiaries and their
respective officers, directors and employees against any losses, claims, damages
or liabilities to which they may become subject to third parties insofar as such
losses, claims, damages or liabilities (or actions in respect thereof) arise out
of any action or failure to act in connection with the operation of Hi-Lo or its
Subsidiaries after the date of this Agreement and prior to the earlier of the
Termination of this Agreement or the Closing Date hereunder taken or not taken
as the case may be, at the request of O'Reilly; provided, however, that Hi-Lo
shall not be liable in any such case to the extent such loss, claim, damage or
liability arises out of requests by O'Reilly made with willful intent to cause
harm to Hi-Lo or its Subsidiaries.

                  TERMINATION, WAIVER, AMENDMENT AND CLOSING

     Section 8.1 Termination or Abandonment. Notwithstanding anything contained
in this Agreement to the contrary, this Agreement may be terminated and
abandoned at any time prior to the Effective Time, whether before or after any
approval of the matters presented in connection with the Merger by the
stockholders of Hi-Lo:

          (a)  by the mutual written consent of Hi-Lo and O'Reilly;


                                      47
<PAGE>
 
     (b)  (i) by either Hi-Lo or O'Reilly if Shares shall not have been
purchased pursuant to the Offer on or before June 30, 1998 and (ii) by Hi-Lo if
after 90 days following the commencement of the Offer, the conditions to the
Offer have not been satisfied or waived and Sub shall not have elected to extend
the Offer; provided, that the party seeking to terminate this Agreement pursuant
to this Section 8.1(b) shall not have breached in any material respect its
obligations under this Agreement in any manner that shall have proximately
contributed to the failure to purchase Shares pursuant to the Offer on or before
such date;

     (c)  by either Hi-Lo or O'Reilly if (i) a statute, rule, regulation or
executive order shall have been enacted, entered or promulgated prohibiting the
purchase of Shares pursuant to the Offer or the consummation of the Merger
substantially on the terms contemplated hereby or (ii) an order, decree, ruling
or injunction shall have been entered permanently restraining, enjoining or
otherwise prohibiting the purchase of Shares pursuant to the Offer or
consummation of the Merger substantially on the terms contemplated hereby and
such order, decree, ruling or injunction shall have become final and non-
appealable; provided, that the party seeking to terminate this Agreement
pursuant to this Section 8.1(c)(ii) shall have used its reasonable best efforts
to remove such injunction, order or decree;

     (d)  by Hi-Lo prior to the purchase of Shares pursuant to the Offer if the
Board of Directors of Hi-Lo determines in good faith based upon advice of its
outside counsel (i) that a Takeover Proposal constitutes a Superior Proposal and
(ii) that failure to accept such Superior Proposal will violate its obligations
or duties to Hi-Lo and Hi-Lo's stockholders under applicable law, provided, that
this Agreement shall not terminate pursuant to this Section 8.1(d) unless (A) 
Hi-Lo has provided O'Reilly with two business day's prior written notice of its
intention to accept such Superior Proposal, together with a detailed description
of the terms and conditions of such Superior Proposal and (B) simultaneously
with such termination Hi-Lo enters into a definitive acquisition, merger or
similar agreement to effect such Superior Proposal and pays the Termination Fee
(as defined in Section 8.2(b)) required pursuant to Section 8.2(b);

     (e)  by either Hi-Lo or O'Reilly prior to the purchase of any Shares
pursuant to the Offer if the other shall have breached, or failed to comply
with, in any material respect any of its obligations under this Agreement or any
representation or warranty made by such other party shall have been untrue when
made or as of the time of such termination as if made on and as of such time
(except for representations and warranties made as of a specified date, which
need be true

                                      48
<PAGE>
 
only as of the specified date), provided such breach, failure or
misrepresentation is not cured within thirty days after notice thereof from the
other party and with respect to any representation or warranty not qualified by
"Material Adverse Effect," such breaches, failures or misrepresentations,
individually or in the aggregate, results or is reasonably likely to result in a
Material Adverse Effect on Hi-Lo or O'Reilly, as the case may be;

     (f)  by O'Reilly (i) if the Board of Directors of Hi-Lo or any committee of
the Board of Directors of Hi-Lo, (A) shall withdraw, modify or change in any
adverse manner (including by amendment of the Schedule 14D-9) to O'Reilly or Sub
its approval or recommendation of this Agreement, the Offer or the Merger, (B)
shall approve or recommend any Takeover Proposal in each case, other than by
O'Reilly or an affiliate of O'Reilly, or (C) shall resolve to take any of the
actions specified in clauses (A) or (B) above;

     (g)  by Hi-Lo if Sub fails to commence the Offer on or prior to five
business days following the date of initial public announcement of the Offer,
provided that Hi-Lo may not terminate this Agreement pursuant to this Section
8.1(g) if Hi-Lo is at such time in breach in any material respect of its
obligations under this Agreement; or

     (h)  by either of Hi-Lo or O'Reilly if the Offer shall have been
terminated, or the Offer has expired without any Shares being purchased therein;
provided, however that the right to terminate this Agreement under this Section
8.1(g) shall not be available to any party whose failure to fulfill any 
obligation under this Agreement has been the cause of, or resulted in, the
termination of the Offer or the failure of O'Reilly or Sub, as the case may be,
to purchase Shares pursuant to the Offer on or prior to such date;

provided, however, that no termination by Hi-Lo shall be effective pursuant to
Section 8.1(d) under circumstances in which a Termination Fee would be payable
by Hi-Lo under Section 8.2 unless concurrently with such termination, such
Termination Fee is paid in full by Hi-Lo in accordance with the provisions of
Section 8.2.

     Section 8.2 Effect of Termination. In the event of termination of this
Agreement as provided in Section 8.1 hereof, and subject to the provisions of
Section 9.1 hereof, this Agreement (except for the Hi-Lo Confidentiality
Agreement referred to in Section 6.2) shall forthwith become void and there
shall be no liability on the part of any of the Parties, except (i) as set forth
in this Section 8.2 and in


                                      49
<PAGE>
 
Sections 4.11, 5.4, 6.16, 9.2 and 9.12 hereof, and (ii) nothing herein shall
relieve any party from liability for any willful breach hereof.

     (a)  In the event that

          (i)  prior to the termination of this Agreement, any person shall have
     commenced, publicly proposed or communicated to Hi-Lo a Takeover Proposal
     and (w) the Offer shall have remained open for at least 20 business days,
     (x) the Minimum Condition shall not have been satisfied, (y) this Agreement
     shall have been terminated pursuant to Section 8.1(b)(c)(e) or (g) and (z)
     prior to the first anniversary of such termination Hi-Lo shall consummate
     such Takeover Proposal; or

          (ii)  If this Agreement is terminated by Hi-Lo or O'Reilly pursuant to
     Section 8.1(d) or Section 8.1(f), respectively;

then in such event, Hi-Lo shall pay to O'Reilly a termination fee of $4,750,000
(the "Termination Fee"), which amount shall be paid by wire transfer of
immediately available funds to an account designated by O'Reilly.

     (b)  (i) The Termination Fee payable to O'Reilly under Section 8.2(b)(i)
shall be paid promptly but in no event later than one business day after the
specified event shall have occurred; and (ii) the Termination Fee payable to
O'Reilly under Section 8.2(b) (ii) above (A) in the case of a termination by
O'Reilly pursuant to 8.1(f) shall be paid within three business days after
notice of termination, and (B) in the case of a termination by Hi-Lo pursuant to
Sections 8.1(d) shall be paid concurrently with such termination.

     (c)  Hi-Lo and O'Reilly agree that the agreements contained in Section
8.2(b) above are an integral part of the transactions contemplated by this
Agreement. If Hi-Lo fails to promptly pay to O'Reilly or Sub, respectively any
fee due under such Section 8.2(b), Hi-Lo shall pay the costs and expenses
(including legal fees and expenses) in connection with any action, including the
filing of any lawsuit or other legal action, taken to collect payment, together
with interest on the amount of any unpaid fee at the publicly announced prime
rate of NationsBank of Texas, N.A. from the date such fee was required to be
paid. In the event O'Reilly receives any fee pursuant to Section 8.2(b),
O'Reilly shall not assert or pursue in any manner, directly or indirectly, any
claim or cause of action against Hi-Lo or any of its affiliates, officers or
directors based in whole or in part upon a breach of this


                                      50
<PAGE>
 
Agreement by them (except for breaches of Section 6.16) or their receipt,
consideration, negotiation, recommendation, or approval of a Takeover Proposal
or the exercise by Hi-Lo of its right of termination under Section 8.1(d).

     Section 8.3 Amendment or Supplement. Subject to applicable law, at any time
before or after approval of the matters presented in connection with the Merger
by the stockholders of Hi-Lo and prior to the Effective Time, this Agreement may
be amended or supplemented in writing by Hi-Lo and O'Reilly with respect to any
of the terms contained in this Agreement, except that following approval by the
stockholders of Hi-Lo, no such amendment or supplement shall reduce the amount
or change the form of the Merger Consideration, without further approval by the
stockholders of Hi-Lo.

     Section 8.4 Extension of Time, Waiver, Etc. At any time prior to the
Effective Time, Hi-Lo and O'Reilly may to the extent legally allowed: (a) extend
the time for the performance of any of the obligations or acts of the other
party; (b) waive any inaccuracies in the representations and warranties of the
other party contained herein or in any document delivered pursuant hereto; or
(c) waive compliance with any of the agreements or conditions of the other
party contained herein.

     Notwithstanding the foregoing, no failure or delay by Hi-Lo or O'Reilly in
exercising any right hereunder shall operate as a waiver thereof nor shall any
single or partial exercise thereof preclude any other or further exercise
thereof or the exercise of any other right hereunder. Any agreement on the part
of a party hereto to any such extension or waiver shall be valid only if set
forth in an instrument in writing signed each of the parties.

expenses, except that the expenses incurred in connection with the printing and
mailing of Schedule 14D-9, and the Offer Documents and the filing fee required

the Securities Act or the Exchange Act shall be shared equally by Hi-Lo and

O'Reilly.

                                    ANNEX A
                        Certain Conditions of the Offer


     Notwithstanding any other provisions of the Offer, and in addition to (and
not in limitation of) Sub's rights to extend the Offer under certain
circumstances (subject to the provisions of the Merger Agreement), Sub shall not
be required to accept for payment or, subject to any applicable rules and
regulations of the SEC, including Rule 14e-1(c) under the Exchange Act (relating
to the Sub's obligation to pay for or return tendered Shares promptly after
termination or withdrawal of the Offer), pay for, and may delay the acceptance
for payment of or, subject to other restrictions referred to above, the payment
for, any tendered Shares, and may terminate the Offer and not accept for payment
any Shares, if (i) any applicable waiting period under the HSR Act has not
expired or terminated prior to the expirations of the Offer, (ii) the Minimum
Condition has not been satisfied, or (iii) at any time on or after the date of
the Merger Agreement and before the time of acceptance of Shares for payment
pursuant to the Offer, any of the following events shall have occurred.

     (a)  there shall be any statute, rule, regulation, judgment, order or
injunction enacted, entered, enforced, promulgated, or deemed applicable,
pursuant to an authoritative interpretation by or on behalf of a Governmental
Entity, to the Offer or the Merger that (i) prohibits or imposes any limitations
on O'Reilly's or Sub's ownership or operation (or that of any of their
respective Subsidiaries or affiliates) of all or a portion of their or Hi-Lo's
businesses or assets, or to compel O'Reilly or Sub or their respective
Subsidiaries and affiliates to dispose of or hold separate any portion of the
business or assets of Hi-Lo or O'Reilly and their respective subsidiaries,
which prohibition, limitation, disposition or hold separate obligation could
reasonably be expected to have a Material Adverse Effect on O'Reilly and its
Subsidiaries, (ii) restrain or prohibit the making or consummation of the Offer
or the Merger or the performance of any of the other transactions contemplated
by the Agreement, (iii) imposes material limitations on the ability of Sub, or
render Sub unable, to accept for payment, pay for or purchase some or all of the
Shares pursuant to the Offer and the Merger or (iv) imposes material limitations
on the ability of Sub or O'Reilly effectively to exercise full rights of
ownership of the Shares, including, without limitation, the right to vote the
Shares purchased by it on all matters properly presented to Hi-Lo's
stockholders;


                                      57
<PAGE>
 
     (b)  (i) the Board of Directors of Hi-Lo (or any committee thereof) shall
have withdrawn, modified or changed in any adverse manner to O'Reilly and Sub
its approval or recommendation of the Offer or the Merger or the Agreement, or
shall have endorsed, approved or recommended any other Takeover Proposal or (ii)
Hi-Lo shall have entered into any agreement with respect to any Superior
Proposal in accordance with Section 8.1(d) of the Agreement;

     (c)  the representations and warranties of Hi-Lo set forth in the Agreement
shall not be true and correct, in each case (i) as of the date referred to in
any representation or warranty which addresses matters as of a particular date,
or (ii) as to all other representations and warranties, as of the date of the
Agreement and as of the scheduled expiration of the Offer, and with respect to
any representations or warranties not qualified by "Material Adverse Effect,"
unless the inaccuracies under such representations and warranties, taking all
the inaccuracies under all such representations and warranties together in their
entirety, do not, individually or in the aggregate, result in a Material Adverse
Effect on Hi-Lo;

     (d)  Hi-Lo shall have failed to perform any obligation or to comply with
any agreement or covenant to be performed or complied with by it under the
Agreement other than any failure which would not have, either individually or in
the aggregate, a Material Adverse Effect on Hi-Lo; or

     (e)  the Agreement shall have been terminated by Hi-Lo or O'Reilly or Sub
in accordance with its terms or O'Reilly or Sub shall have reached an agreement
or understanding in writing with Hi-Lo providing for termination or amendment of
the Offer or delay in payment for the Shares;

which, in the reasonable judgment of O'Reilly and Sub, in any such case, and
regardless of the circumstances giving rise to any such conditions, makes it
inadvis able to proceed with the Offer and/or with such acceptance for payment
of or payment for Shares.

     The foregoing conditions (other than the Minimum Condition) are for the
sole benefit of O'Reilly and Sub and, subject to the Merger Agreement, may be
asserted by O'Reilly or Sub regardless of the circumstances giving rise to such
condition or may be waived by O'Reilly or Sub in whole or in part at any time
and from time to time in its sole discretion. The failure by O'Reilly or Sub at
any time to exercise any of the foregoing rights shall not be deemed a waiver of
any such right, and each such right shall be deemed an ongoing right which may
be asserted at any time and from time to time.

[LETTERHEAD OF SBC WARBURG DILLON READ INC.]






                                                November 26, 1997


O'Reilly Automotive Inc.
P.O. Box 1156
233 S. Patterson 
Springfield, MO 65801

Attention: Mr. David E. O'Reilly

Gentlemen:

     In connection with your consideration of a possible negotiated transaction 
by you or one or more of your affiliates (as the term "affiliate" is defined in 
the Securities Exchange Act of 1934, as amended (the "Exchange Act")), involving
Hi-Lo Automotive, Inc. (the "Company") (a "Transaction"), the Company, Dillon, 
Read & Co. Inc. ("Dillon Read"), acting as the Company's exclusive financial 
advisor in connection with the proposed Transaction, and their respective 
advisors and agents are prepared to make available to you certain information 
which is non-public, confidential or proprietary in nature.

     By execution of this letter agreement (the "Agreement"), you agree to treat
confidentially all such information whether written or oral (the "Evaluation 
Material"), and to observe the terms and conditions set forth herein. You also 
agree that, subject to the fourth paragraph of this Agreement, prior to giving 
any of your directors, officers, employees, partners, affiliates, agents, 
advisors or representatives (hereinafter, "Representatives") access to any of 
the Evaluation Material, you shall require each such Representative to be bound 
by the terms of this Agreement to the same extent as if they were parties 
hereto. You further agree to be responsible for any breach of this Agreement by 
any of your Representatives.

     For purposes of the Agreement, Evaluation Material shall include, without 
limitation, all information, data, reports, analyses, compilations, studies, 
interpretations, projections, forecasts, records, and other materials (whether 
prepared by the Company, Dillon Read or otherwise and in whatever form 
maintained, whether documentary, computerized or 

                                       1

otherwise), regardless of the form of communication, that contain or otherwise
reflect information concerning the Company that you or your Representatives may
be provided by or on behalf of the Company or Dillon Read in the course of your
evaluation of a possible Transaction. The term "Evaluation Material" shall also
include all information, data, reports, analyses, computations, studies,
interpretations, projections, forecasts, records, notes, memoranda, summaries or
other materials in whatever form maintained, whether documentary, computerized
or otherwise, whether prepared by you or your Representative or others, that
contain or otherwise reflect or are based upon, in whole or in part, any such
Evaluation Material or that reflect your review of, or interest in, all or any
portion of the Company (the "Notes"). This Agreement shall be inoperative as to
those particular portions of the Evaluation Material (i) become generally
available to the public other than as result of disclosure by you or any of your
Representatives, (ii) were available to you on a non-confidential basis prior to
the disclosure of such Evaluation Material to you pursuant to this Agreement,
provided that the source of such information was not known by you or any of your
Representatives, after reasonable investigation, to be bound by a
confidentiality agreement with or other contractual, legal or fiduciary
obligation of confidentiality to the Company or any of its affiliates with
respect to such material or (iii) becomes available to you on a non-confidential
basis from a source other than the Company or its agents, advisors or
representatives provided that the source of such information was not known by
you or any of your Representatives, after reasonable investigation, to be bound
by a confidentiality agreement with or other contractual, legal or fiduciary
obligation of confidentiality to the Company or any of its affiliates with
respect to such material.

     You agree that you will not use the Evaluation Material for any purpose 
other than determining whether you wish to enter into or pursue a Transaction. 
You agree not to disclose or allow disclosure to others of any Evaluation 
Material; provided that, subject to the second paragraph of this Agreement. You
may disclose Evaluation Material to your Representatives to the extent necessary
to permit such Representatives to assist you in making the determination
referred to in the prior sentence. You shall maintain a list of those of your
Representatives to whom Evaluation Material has been disclosed (which list shall
be presented to the Company upon request) and shall take all reasonable measures
(including but not limited to court proceedings), at your sole expense, to
restrain your Representatives from prohibited or unauthorized disclosure or use
of the Evaluation Material. In furtherance of the foregoing, you agree that you
will not use the Evaluation Material in any way directly or indirectly
detrimental to the Company. In particular you agree that for a period of 12
months from the date of the signing of this Agreement you and your affiliates
will not knowingly, as a result of knowledge or information obtained from the
Evaluation Material or otherwise in connection with a possible Transaction; (i)
divert or attempt to divert any business or customer of the Company or any of
its affiliates; nor (ii) employ or attempt to employ or divert a managerial,
professional or executive employee of the Company or any of its affiliates.

     In addition, you agree that you will not make any disclosure (i) that you, 
Dillon Read or the Company are having or have had discussions, or that you have 
received Evaluation Material from the Company or Dillon Read concerning a 
Transaction, (ii) that you are considering a possible Transaction or (iii)
concerning any discussions related to a possible Transaction, including the
status thereof, any termination thereof, any decision on your part to no longer
consider any such Transaction or any of the terms, conditions or other facts
with respect thereto; provided that you may make such disclosure if you have
received the written opinion of your counsel that such disclosure must be made
by you in order that you not commit a violation of law and, prior to such
disclosure, you promptly advise and consult with the Company and its legal
counsel concerning the information you propose to disclose. Without limiting the
generality of the foregoing, you further agree that, without the prior written
consent of the Company, you will not, directly or indirectly, enter into any
agreement, arrangement or understanding with any person regarding a possible
Transaction. The term "person" as used in this letter shall be broadly
interpreted to include, without limitation, the media and any corporation,
partnership, group, individual or other entity.

     Although the Company and Dillon Read have endeavored to include in the 
Evaluation Material information known to them which they believe to be relevant 
for the purpose of your investigation, you understand and agree that none of the
Company, Dillon Read or any of their affiliates, agents, advisors or 
representatives (i) have made or make any representation or warranty, expressed 
or implied, as to the accuracy or completeness of the Evaluation Material or 
(ii) shall have any liability whatsoever to you or your Representatives relating
to or resulting from the use of the Evaluation Material or any errors therein or
omissions therefrom.

     Without limiting the generality of the immediately preceding paragraph, the
Evaluation Material may include certain statements, estimates and projections
provided by the Company with respect to the anticipated future performance of
the Company. Such statements, estimates and projections reflect various
assumptions made by the Company concerning anticipated results, which
assumptions may or may not prove to be correct. No representations are made as
to accuracy of such assumptions, statements, estimates or projections, including
the budget. The only information that will have any legal effect will be 
specifically represented in a definitive purchase agreement; in no event will 
such definitive agreement contain any representation as to any projections.

     In the event that you or anyone to whom you transmit any Evaluation 
Material in accordance with this Agreement are requested or required (by 
deposition, interrogatories, requests for information or documents in legal 
proceedings, subpoenas, civil investigative demand or similar process), in 
connection with any proceeding, to disclose any Evaluation Material, you will 
give the Company prompt written notice of such request or requirement so that 
the Company may seek an appropriate protective order or other remedy and/or 
waive


                                       3
<PAGE>
 
[LOGO OF SBC WARBURG DILLON READ]


compliance with the provisions of this Agreement, and you will cooperate with
the Company to obtain such protective order. In the event that such protective
order or other remedy is not obtained or the Company waives compliance with the
relevant provisions of this Agreement, you (or such other persons to whom such
request is directed) will furnish only that portion of the Evaluation Material
which, in the written opinion of your counsel, is legally required to be
disclosed. It is further agreed that, if in the absence of a protective order
you (or such other persons to whom such request is directed) are nonetheless
legally compelled to disclose such information, you may make such disclosure
without liability hereunder, provided that you give the Company notice of the
information to be disclosed as far in advance of its disclosure as is
practicable and, upon the Company's request, use your best efforts to obtain
assurances that confidential treatment will be accorded to such information and,
provided further, that such disclosure was not caused by and did not result from
a previous disclosure by you or any of your Representatives not permitted
hereunder.

     If you decide that you do not wish to proceed with a Transaction, you will
promptly notify Dillon Read of that decision. In that case, or if the Company
shall elect at any time to terminate further access by you to the Evaluation
Material for any reason, you will within five business days return to us all
copies of the Evaluation Material in the possession of you or your affiliates or
your Representatives, will destroy all Notes and will further deliver to Dillon
Read and the Company a certificate executed by one of your duly authorized
executive officers indicating that the requirements of this sentence have been
satisfied in full. Notwithstanding the return or destruction of Evaluation
Material and Notes, you and your Representatives will continue to be bound by
your obligations of confidentiality and other obligations hereunder.

     You hereby acknowledge that you are aware that the securities laws of the
United States prohibit any person who has material, non-public information
concerning the Company or a possible Transaction involving the Company from
purchasing or selling securities in reliance upon such information or from
communicating such information to any other person or entity under circumstances
in which it is reasonably foreseeable that such person or entity is likely to
purchase or sell such securities in reliance upon such information.

     You understand that (i) the Company and Dillon Read shall conduct the
process for a possible Transaction as they in their sole discretion shall
determine (including, without limitation, negotiating with any prospective buyer
and entering into definitive agreements without prior notice to you or any other
person), (ii) any procedures relating to such a Transaction may be changed at
any time without notice to you or any other person, (iii) the Company shall have
the right to reject or accept any potential buyer, proposal or offer, for any
reason whatsoever in its sole discretion, and (iv) neither you nor any of your
Representatives shall have any claims whatsoever against the Company or Dillon
Read or any of their respective directors, officer, stockholders, owners,
affiliates or agents arising out or relating to

                                       4

the Transaction (other than those against the parties to a definitive agreement 
with you in accordance with the terms thereof).

     It is further understood and agreed that Dillon Read will arrange for 
appropriate contacts for due diligence. It is also understood and agreed that 
all (i) communications regarding a possible Transaction, (ii) requests for 
additional information, (iii) requests for facility tours or management meetings
and (iv) discussions or questions regarding procedures, will be submitted or 
directed exclusively to Dillon Read, and that none of you or your 
Representatives who are aware of the Evaluation Material and/or the possibility 
of a Transaction will initiate or cause to be initiated any communication with 
any director, officer or employee of the Company concerning the Evaluation 
Material or a Transaction.

     You agree that unless and until a definitive agreement between the Company 
and you with respect to any Transaction has been executed and delivered, neither
the Company nor you will be under any legal obligation of any kind whatsoever 
with respect to any Transaction, other than as specifically set forth herein.

     You agree that money damages would not be a sufficient remedy for any
breach of this Agreement by you or your Representatives, that in addition to all
other remedies the Company shall be entitled to specific performance and
injunctive or other equitable relief as a remedy for any such breach, and you
further agree to waive, and to use your best efforts to cause your
Representatives to waive, any requirement for the securing or posting of any
bond in connection with such remedy. In the event of litigation relating to this
Agreement, if a court of competent jurisdiction determines that you or any of
your Representatives have breached this Agreement, you shall be liable and pay
to the Company the reasonable legal fees incurred by the Company in connection
with such litigation, including any appeal therefrom.

     The Company reserves the right to assign its rights, powers and privileges 
under this Agreement (including, without limitation, the right to enforce the 
terms of this letter agreement) to any person who enters into a Transaction.

     All modifications of, waivers of and amendments to this Agreement or any
part hereof must be in writing signed on behalf of you and the Company or by you
and Dillon Read, as agent for the Company. You acknowledge that the Company is
intended to be benefited by this Agreement and that the Company shall be
entitled, either alone or together with Dillon Read, to enforce this Agreement
and to obtain for itself the benefit of any remedies that may be available for
the breach hereof.

     It is further understood and agreed that no failure or delay by the Company
in exercising any right, power or privilege under this Agreement shall operate 
as a waiver thereof

                                       5

[LOGO OF SBC WARBURG DILLON READ]

nor shall any single or partial exercise thereof preclude any other or further 
exercise of any right, power or privilege hereunder.

     In the event that any provision or portion of this Agreement is determined
to be invalid or unenforceable for any reason, in whole or in part, the
remaining provisions of this Agreement shall be unaffected thereby and shall
remain in full force and effect to fullest extent permitted by applicable law.

     This Agreement shall be governed by, and construed and enforced in
accordance with, the laws of the State of New York.

     If you are in agreement with the foregoing, please so indicate by signing,
dating and returning one copy of this Agreement, which will constitute our
agreement with respect to the matters set forth herein.

   

                                         Very truly yours,
