To the Holders of Shares of Common Stock of Triangle Pacific Corp.:
 
                                 INTRODUCTION
 
THE OFFER
 
  Sapling Acquisition, Inc. (the "Purchaser"), a Delaware corporation and a
wholly owned subsidiary of Armstrong World Industries, Inc., a Pennsylvania
corporation ("Parent"), hereby offers to purchase all outstanding shares (the
"Shares") of common stock, par value $.01 per share (the "Common Stock"), of
Triangle Pacific Corp., a Delaware corporation (the "Company"), at a price of
$55.50 per Share, net to the seller in cash, without interest thereon (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
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, stock transfer taxes on the purchase of Shares pursuant to the
Offer. However, any tendering stockholder or other payee who fails to complete
and sign the Substitute Form W-9 included in the Letter of Transmittal may be
subject to a required backup federal income tax withholding of 31% of the
gross proceeds payable to such stockholder or other payee pursuant to the
Offer. See Section 3. The Purchaser will pay all charges and expenses of J.P.
Morgan Securities Inc., as Dealer Manager (in such capacity, the "Dealer
Manager"), ChaseMellon Shareholder Services, L.L.C., as Depositary (the
"Depositary"), and Morrow & Co., Inc., as Information Agent (the "Information
Agent"), incurred in connection with the Offer. See Section 16.
 
  THE BOARD OF DIRECTORS OF THE COMPANY HAS UNANIMOUSLY APPROVED (WITH ONE
MEMBER BEING ABSENT) EACH OF THE OFFER, THE MERGER (AS DEFINED HEREIN) AND THE
MERGER AGREEMENT (AS DEFINED HEREIN), HAS DETERMINED THAT EACH OF THE OFFER,
THE MERGER AND THE MERGER AGREEMENT IS FAIR TO, AND IN THE BEST INTERESTS OF,
THE COMPANY'S STOCKHOLDERS AND RECOMMENDS THAT STOCKHOLDERS ACCEPT THE OFFER
AND TENDER THEIR SHARES PURSUANT TO THE OFFER.
 
  The Company's financial advisor, Salomon Smith Barney ("Salomon"), has
delivered to the Company's Board of Directors its written opinion, dated June
12, 1998, to the effect that, as of the date of such opinion, the $55.50 per
Share cash consideration to be received by the holders of Shares in the Offer
and the Merger is fair to such holders from a financial point of view. The
full text of the opinion, which sets forth the factors considered and the
assumptions made by such financial advisor, are contained in the Company's
Solicitation/ Recommendation Statement on Schedule 14D-9 (the "Schedule 14D-
9"), which is being mailed to stockholders herewith. STOCKHOLDERS ARE URGED
TO, AND SHOULD, READ SUCH OPINION CAREFULLY IN ITS ENTIRETY.
 
  The Offer is conditioned upon, among other things, (1) there being validly
tendered and not withdrawn prior to the Expiration Date (as defined in Section
1) such number of shares that would constitute a majority of the outstanding
Shares (determined on a fully diluted basis) (the "Minimum Condition"), (2)
any waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of
1976, as amended, and the regulations thereunder (the "HSR Act") applicable to
the purchase of Shares pursuant to the Offer having expired or been terminated
(the "HSR Condition"), and (3) the satisfaction or waiver of certain other
conditions to the obligations of the Purchaser and the Company to consummate
the Offer and the transactions contemplated by the Merger Agreement as
described in Section 14. The Purchaser reserves the right (subject to
obtaining the consent of the Company and the applicable rules and regulations
of the Securities and Exchange Commission (the "Commission")), which it
presently has no intention of exercising, to waive or amend the Minimum
Condition and to elect to purchase, pursuant to the Offer, less than the
Minimum Number of Shares (as defined herein). In addition, the Purchaser
reserves the right, subject only to the applicable rules and regulations of
the Commission,
<PAGE>
 
to waive each of the other conditions (other than the Minimum Condition) to
the obligations of the Purchaser to consummate the Offer and the transactions
contemplated by the Merger Agreement. See Sections 1 and 14.
 
  The Offer is being made pursuant to an Agreement and Plan of Merger, dated
as of June 12, 1998 (the "Merger Agreement"), by and among Parent, the
Purchaser and the Company pursuant to which, following the consummation of the
Offer and the satisfaction or waiver of the conditions set forth in the Merger
Agreement, the 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") of the Merger and will
be a wholly owned subsidiary of Parent. In the Merger, each Share issued and
outstanding (other than shares of Common Stock held directly or indirectly by
the Company (whether as treasury stock or otherwise), Parent, Purchaser or any
other wholly owned subsidiary of Parent and other than Shares owned by
stockholders who have properly exercised rights of appraisal (if any) under
Section 262 of the General Corporation Law of the State of Delaware (the
"DGCL") will be converted into the right to receive the Offer Price, without
interest (the "Merger Consideration"). The Merger Agreement is more fully
described in Section 12.
 
  The Merger Agreement provides that, promptly upon the purchase of and
payment for Shares by Parent or any of its subsidiaries of greater than 50% of
the outstanding Shares (on a fully diluted basis) pursuant to the Offer,
Parent shall be entitled to designate such number of directors, rounded up to
the next whole number, on the Board of Directors as will give the Parent
representation on the Board of Directors equal to the product of the total
number of directors on the Board of Directors multiplied by the percentage
that the aggregate number of Shares then beneficially owned by the Purchaser,
Parent and any of their affiliates following such purchase bears to the total
number of Shares then outstanding. In the Merger Agreement, the Company has
agreed to take any and all actions within the Company's power which are
necessary to cause the Purchaser's designees to be appointed to the Board of
Directors of the Company, including by increasing the size of the Board of
Directors or using its best efforts to cause incumbent directors to resign or
both. In addition, the Company has agreed to use its best efforts to cause
persons designated by Parent to constitute the same percentage of each
committee of the Board of Directors, each board of directors of each
subsidiary of the Company and each committee of each such board as such
persons represent on the Board of Directors of the Company. See Section 12.
 
  The consummation of the Merger is subject to the satisfaction or waiver of
certain conditions, including, if required by law, the approval and adoption
of the Merger Agreement by the requisite vote of the stockholders of the
Company. Under the Company's Certificate of Incorporation and the DGCL, except
as otherwise described below, the affirmative vote of the holders of a
majority of the outstanding Shares is required to approve and adopt the Merger
Agreement and the Merger. Consequently, if the Purchaser acquires (pursuant to
the Offer or otherwise) at least a majority of the then outstanding Shares,
calculated on a fully-diluted basis, the Purchaser will have sufficient voting
power to approve and adopt the Merger Agreement and the Merger without the
vote of any other stockholder. See Section 12.
 
  Under the DGCL, if the Purchaser acquires, pursuant to the Offer or
otherwise, at least 90% of the then outstanding Shares, the Purchaser will be
able to approve and adopt the Merger Agreement and the transactions
contemplated thereby, including the Merger, without a vote of the Company's
stockholders. In such event, Parent and the Purchaser intend to take all
necessary and appropriate action to cause the Merger to become effective as
soon as practicable after such acquisition, without a meeting of the Company's
stockholders. If, however, the Purchaser does not acquire at least 90% of the
then outstanding Shares pursuant to the Offer or otherwise and a vote of the
Company's stockholders is required under Delaware Law, a longer period of time
will be required to effect the Merger. See Section 12.
 
  As an inducement to Parent and the Purchaser to enter into the Merger
Agreement described below, TCW Special Credits Fund IIIb, a California limited
partnership, TCW Special Credits Trust, a California collective investment
trust, TCW Special Credits Trust IIIb, a California collective investment
trust, TCW Special Credits Fund V, a California limited partnership,
Weyerhaeuser Company Master Retirement Trust, a special account, The Common
Fund for Bond Investment, a special account, and TCW Asset Management Company,
a California corporation (collectively, the "Stock Tender Parties"), each
entered into a Stock Tender Agreement (the "Stock
 
                                       2
<PAGE>
 
Tender Agreement"), dated as of June 12, 1998, with Parent and the Purchaser.
The Stock Tender Parties collectively own 5,909,184 Shares, or approximately
35% of the outstanding Shares calculated on a fully diluted basis as of June
9, 1998. Pursuant to the Stock Tender Agreement, the Stock Tender Parties have
agreed, so long as the Board of Directors of the Company, Parent or the
Purchaser has not terminated the Merger Agreement, validly to tender pursuant
to the Offer, and not withdraw, all Shares which are owned of record or
beneficially by them prior to the Expiration Date (as defined herein). The
Stock Tender Agreement is more fully described in Section 12.
 
  The Company has informed the Purchaser that as of the close of business on
June 9, 1998, there were 14,766,575 Shares issued and outstanding and
2,510,021 Shares reserved for issuance upon the exercise of outstanding
options, warrants or other rights to acquire Shares, of which 2,184,428 Shares
are covered by options, warrants or other rights to acquire Shares that are or
will be vested. Based upon the foregoing, the Purchaser believes that the
Minimum Condition will be satisfied if at least 8,475,502 Shares (the "Minimum
Number of Shares") are validly tendered and not withdrawn prior to the
Expiration Date (including those Shares tendered pursuant to the Stock Tender
Agreement). If the Minimum Condition is satisfied and the Purchaser accepts
for payment Shares tendered pursuant to the Offer, the Purchaser will be able
to elect a majority of the members of the Company's Board of Directors and to
effect the Merger without the affirmative vote of any other stockholder of the
Company.

  The Merger Agreement is more fully described in Section 12. Certain Federal
income tax consequences of the sale of Shares pursuant to the Offer and the
exchange of Shares for the Merger consideration pursuant to the Merger are
described in Section 5.
 
  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; EXPIRATION DATE. 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 extension or amendment), the Purchaser will accept
for payment and pay for all Shares validly tendered prior to the Expiration
Date and not withdrawn in accordance with Section 4. The term "Expiration
Date" means 12:00 midnight, New York City time, on Friday, July 17, 1998,
unless and until the Purchaser, in accordance with the terms of the Merger
Agreement, shall have extended the period of time during which the Offer is
open, in which event the term "Expiration Date" shall mean the latest time and
date at which the Offer, as so extended by the Purchaser, shall expire.
 
  Consummation of the Offer is conditioned upon, among other things,
satisfaction of each of the Minimum Condition and the HSR Condition. The Offer
also is subject to certain other conditions set forth in Section 14 (together
with the Minimum Condition and the HSR Condition, the "Offer Conditions"). If
any of the Offer Conditions are not satisfied prior to the Expiration Date,
the Purchaser reserves the right (but shall not be obligated) to (i) decline
to purchase any or all of the Shares tendered and terminate the Offer, and
return all such tendered Shares to tendering stockholders, (ii) waive or
reduce the Minimum Condition (only with the consent of the Company) or waive
any or all other Offer Conditions and, subject to complying with applicable
rules and regulations of the Commission, purchase all Shares validly tendered,
(iii) subject to the terms of the Merger Agreement, extend the Offer and,
subject to the right of stockholders to withdraw Shares until the Expiration
Date, retain the Shares which have been tendered during the period or periods
for which the Offer is extended or (iv) subject to the terms of the Merger
Agreement, otherwise amend the Offer.
 
  Subject to the terms of the Merger Agreement and the applicable rules and
regulations of the Commission, except as described below, the Purchaser
expressly reserves the right, in its sole discretion, at any time and from
time to time, and regardless of the occurrence of any of the events specified
in Section 14, by giving oral or written notice to the Depositary, as
described below, to (i) extend the period of time during which the Offer is
open, and thereby delay acceptance of such payment of, and the payment for any
Shares and (ii) amend the Offer in any other respect. 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. 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 any tendered Shares. See Section 4.
 
  There can be no assurance that the Purchaser will exercise its right to
extend the Offer (other than as required by the Merger Agreement). Any
extension, waiver, amendment or termination will be followed as promptly as
practicable by 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. 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
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.
 
  In the Merger Agreement the Purchaser has agreed that it will not, without
the prior consent of the Company, extend the Offer, except that the Purchaser
may, without the consent of the Company, (i) extend the Offer on one or more
occasions for an aggregate period of not more than 20 days, if at the
scheduled or extended Expiration Date of the Offer, the Minimum Condition
shall not be satisfied, (ii) extend the Offer from time to
 
                                       4
<PAGE>
 
time until the earlier to occur of (x) the satisfaction or waiver of all Offer
Conditions or (y) August 31, 1998, if at the scheduled or extended Expiration
Date any of the Offer Conditions (other than the Minimum Condition) which are
reasonably capable of being satisfied shall not be satisfied or waived;
provided, however, that notwithstanding the foregoing, if all Offer Conditions
other than the HSR Condition have been satisfied or waived, and the HSR
Condition is reasonably capable of being satisfied, the Purchaser may extend
the Offer without the consent of the Company until October 31, 1998 (either
such date, as applicable, being the "Extension Date"), (iii) extend the Offer
for any period required by any rule, regulation, interpretation or position of
the Commission or the staff thereof applicable to the Offer and (iv) extend
the Offer on one or more occasions for an aggregate period of not more than 10
business days beyond the latest Expiration Date that would otherwise be
permitted under clause (i), (ii) or (iii) of this sentence, if on such
Expiration Date there shall not have been tendered at least 90% of the
outstanding Shares on a fully diluted basis; provided, however, that, if the
Offer is extended pursuant to this clause (iv), certain of the Offer
Conditions shall be deemed satisfied at all times thereafter. The Merger
Agreement further provides that if all of the Offer Conditions have not been
satisfied or waived on any scheduled Expiration Date of the Offer then,
provided that all such Offer Conditions are reasonably capable of being
satisfied, Purchaser, at the request of the Company, will extend the Offer
from time to time until the earlier to occur of (i) the satisfaction or waiver
of such Offer Conditions or (ii) the Extension Date. As used in this Offer to
Purchase, "business day" has the meaning set forth in Rule 14d-1 under the
Exchange Act.
 
  In addition, the Purchaser has agreed in the Merger Agreement that it will
not without the consent of the Company, (i) amend or waive the Minimum
Condition, (ii) decrease the Offer Price, (iii) decrease the number of Shares
subject to the Offer, (iv) amend any other term or condition of the Offer in
any manner adverse to the holders of the Shares, or (iv) extend the Offer,
except as provided above.
 
  If the Purchaser extends the Offer or if the Purchaser (whether before or
after its acceptance for payment of Shares) is delayed in its acceptance for
payment of or payment for 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 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 if it waives a material Offer Condition
(including, with the Company's consent, 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 material
changes 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 relative
materiality of the change terms or information. With respect to a change in
price or a change in the percentage of securities sought, a minimum period of
10 business days generally is required to allow for adequate dissemination to
stockholders.
 
  The Company has provided the Purchaser with the Company's stockholder lists
and security position listings for the purpose of disseminating the Offer to
holders of the Shares. This Offer to Purchaser, 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.
 
                                       5

  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, all
Shares validly tendered prior to the Expiration Date (and not properly
withdrawn in accordance with Section 4) as soon as practicable after the
Expiration Date. Any determination concerning the satisfaction of such terms
and conditions shall be within the sole discretion of the Purchaser. See
Section 4. Subject to the terms of the Merger Agreement, the Purchaser
expressly reserves the right, in its sole discretion, to delay acceptance for
payment of, or, subject to the applicable rules of the Commission, payment
for, Shares in order to comply in whole or in part with any applicable law,
including without limitation, the HSR Act. See Section 15. Any such delays
will be effected in compliance with Rule 14e-1(c) under the Exchange Act
(relating to the Purchaser's obligation to pay for or return tendered Shares
promptly after the termination or withdrawal of the Offer).
 
  Parent has filed a Notification and Report Form with respect to the Offer
under the HSR Act. 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 such form was filed, unless early termination of the waiting period is
granted. In addition, the Antitrust Division of the United States Department
of Justice (the "Antitrust Division") or the United States Federal Trade
Commission (the "FTC") may extend the waiting period by requesting additional
information or documentary material from Parent. If such a request is made,
such waiting period will expire at 11:59 p.m., New York City time, on the 10th
day after substantial compliance by Parent with such request. See Section 15
hereof for additional information concerning the HSR Act and the applicability
of the antitrust laws to the Offer.
 
  In all cases, payment for Shares tendered and accepted for payment pursuant
to the Offer will be made only after timely receipt by the Depositary of (i)
the certificate(s) representing tendered Shares (the "Share Certificates") or
timely confirmation of a book-entry transfer (a "Book-Entry Confirmation") of
such Shares (if such procedure is available) into the Depositary's account at
The Depository Trust Company (the "Book-Entry Transfer Facility") pursuant to
the procedures set forth in Section 3, (ii) the Letter of Transmittal (or
facsimile thereof), properly completed and duly executed, or an Agent's
Message (as defined herein) in connection with a book-entry transfer, and
(iii) any other documents required by the Letter of Transmittal.
 
  The term "Agent's Message" means a message, transmitted by the Book-Entry
Transfer Facility to, and received by, the Depositary and forming a part of a
Book-Entry Confirmation, which states that the Book-Entry Transfer Facility
has received an express acknowledgment from the participant in the Book-Entry
Transfer Facility tendering the Shares 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 will be deemed to have accepted for
payment, and thereby purchased, tendered Shares if, as and when the Purchaser
gives oral or written notice to the Depositary of the Purchaser's acceptance
of such Shares for payment. 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 OFFER
PRICE FOR SHARES BE PAID BY THE PURCHASER BY REASON OF 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. If, for any reason
whatsoever, acceptance for payment of or payment for any Shares tendered
pursuant to the Offer is delayed, or the Purchaser is unable to accept for
payment or pay for Shares tendered pursuant to the Offer, then, without
prejudice to the Purchaser's rights set forth herein, the Depositary may,
nevertheless, on behalf of the Purchaser and subject to Rule 14e-1(c) under
the Exchange Act, retain tendered Shares and such Shares may not be withdrawn
except to the extent that the tendering stockholder is entitled to and duly
exercises withdrawal rights as described in Section 4.
 
                                       6
<PAGE>
 
  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 unpurchased 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 the Book-Entry Transfer Facility
pursuant to the procedure set forth in Section 3, such Shares will be credited
to an account maintained at the Book-Entry Transfer Facility), as promptly as
practicable following the expiration or termination of the Offer.
 
  If, prior to the Expiration Date, the Purchaser increases the consideration
offered to stockholders pursuant to the Offer, such increased consideration
will be paid to all stockholders whose Shares are purchased pursuant to the
Offer, regardless of whether those Shares were tendered prior to the increase
in consideration.
 
  Subject to the provisions of the Merger Agreement, the Purchaser reserves
the right to transfer or assign, in whole at any time or in part from time to
time, to Parent or one or more of their 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 and will in no way prejudice the rights of tendering stockholders to
receive payment for Shares validly tendered and accepted for payment pursuant
to the Offer.
 
  3. PROCEDURES FOR TENDERING SHARES
 
  Valid Tender of Shares. Except as set forth below, 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, (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, in each case, prior to the Expiration Date, or
(iii) the tendering stockholder must comply with the guaranteed delivery
procedures described below.
 
  If Share Certificates are forwarded to the Depositary in multiple
deliveries, a properly completed and duly executed Letter of Transmittal (or a
facsimile thereof) must accompany each delivery. No alternative, conditional
or contingent tenders will be accepted and no fractional Shares will be
purchased.
 
  THE METHOD OF DELIVERY OF SHARE CERTIFICATES, THE LETTER OF TRANSMITTAL AND
ALL OTHER REQUIRED DOCUMENTS, INCLUDING DELIVERY THROUGH THE BOOK-ENTRY
TRANSFER FACILITY, IS AT THE OPTION AND RISK OF THE TENDERING STOCKHOLDER, AND
THE DELIVERY 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 make a request to establish an
account with respect to the Shares at the 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 the Book-
Entry Transfer Facility's system may make book-entry delivery of Shares by
causing the Book-Entry Transfer Facility to transfer such Shares into the
Depositary's account at the Book-Entry Transfer Facility in accordance with
the Book-Entry Transfer Facility's procedures for transfer. Although delivery
of Shares may be effected through book-entry transfer at the Book-Entry
Transfer Facility, the Letter of Transmittal or a facsimile thereof, 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 guaranteed delivery procedures described below must be complied
with.
 
                                       7
<PAGE>
 
  REQUIRED DOCUMENTS MUST BE TRANSMITTED TO AND RECEIVED BY THE DEPOSITARY AT
ONE OF ITS ADDRESSES SET FORTH ON THE BACK COVER PAGE OF THIS OFFER TO
PURCHASE. DELIVERY OF DOCUMENTS TO THE BOOK-ENTRY TRANSFER FACILITY IN
ACCORDANCE WITH THE BOOK-ENTRY TRANSFER FACILITY'S PROCEDURES DOES NOT
CONSTITUTE DELIVERY TO THE DEPOSITARY.
 
  Signature Guarantees. No signature guarantee is required on the Letter of
Transmittal if 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 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, an
"Eligible Institution"). In all other cases, all signatures on the Letter of
Transmittal must be guaranteed by an Eligible Institution. See Instruction 1
of the Letter of Transmittal.
 
  If 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 (or a Book-Entry Confirmation) representing
  all tendered Shares in proper form for transfer together with a properly
  completed and duly executed Letter of Transmittal (or facsimile thereof),
  with any required signature guarantees (or, in the case of a book-entry
  transfer, an Agent's Message) and any other documents required by the
  Letter of Transmittal are received by the Depositary within three Nasdaq
  trading days after the date of execution of such Notice of Guaranteed
  Delivery.
 
  Any Notice of Guaranteed Delivery may be delivered by hand or transmitted by
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 provisions hereof, payment for Shares accepted for
payment pursuant to the Offer will in all cases be made only after timely
receipt by the Depositary of Share Certificates for, or of Book-Entry
Confirmation with respect to, such Shares, a properly completed and duly
executed Letter of Transmittal (or facsimile thereof), together with any
required signature guarantees (or, in the case of a book-entry transfer, an
Agent's Message) and any other documents required by the Letter of
Transmittal. Accordingly, payment might not be made to all tendering
stockholders at the same time and will depend upon when Share Certificates are
received by the Depositary or Book-Entry Confirmations with respect to such
Shares are received into the Depositary's account at the Book-Entry Transfer
Facility.
 
  The valid tender of Shares pursuant to one of the procedures described above
will constitute a binding agreement between the tendering Stockholder and the
Purchaser upon the terms and subject to the conditions of the Offer.
 
 
                                       8

  Appointment as Proxy. 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 or other securities issued or
issuable in respect of such Shares on or after June 12, 1998). All such
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 Offer. Upon such
acceptance for payment, all prior proxies given by such stockholder with
respect to such Shares and other securities will, without further action, be
revoked, and no subsequent proxies may be given. 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,
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 rights with respect to such Shares.
 
  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 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, to waive any of the Offer
Conditions (subject to restrictions in the Merger Agreement) 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.
 
  Backup Withholding. In order to avoid "backup withholding" of Federal income
tax on payments of cash pursuant to the Offer, a stockholder surrendering
Shares in the Offer must, unless an exemption applies, provide the Depositary
with such stockholder's correct taxpayer identification number ("TIN") on a
Substitute Form W-9 and certify under penalty of perjury that such TIN is
correct and that such stockholder is not subject to backup withholding.
Certain stockholders (including, among others, all corporations and certain
foreign individuals and entities) are not subject to backup withholding. If a
stockholder does not provide its correct TIN or fails to provide the
certifications described above, the Internal Revenue Service ("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% of the
amount payable to such stockholder. 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 proven in a manner satisfactory
to the Purchaser and the Depositary). Noncorporate foreign stockholders 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 10 to the Letter of Transmittal.
 
  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 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 the Extension Date.
 
                                       9
<PAGE>
 
  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; subject, however, to the Purchaser's obligation, pursuant to Rule
14e-1(c) under the Exchange Act, to pay for the tendered Shares or return
those Shares promptly after termination or withdrawal of the Offer. Any such
delay will be accompanied by an extension of the Offer to the extent required
by law.
 
  For a withdrawal to be effective, a written 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 (if Share
Certificates have been tendered) 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
otherwise identified to the Depositary, then prior to the release of such
Share Certificates, the serial numbers shown on the particular Share
Certificates to be withdrawn 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 Book-Entry
Transfer Facility to be credited with the withdrawn Shares, in which case a
notice of withdrawal will be effective if delivered to the Depositary by any
method of delivery described in the first sentence of this paragraph.
Withdrawals of Shares may not be rescinded.
 
  All questions as to the form and validity (including, without limitation,
time of receipt) of notices of withdrawal will be determined by the Purchaser,
in its sole discretion, the determination of which 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 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. However, withdrawn Shares may be
retendered at any time prior to the Expiration Date by following one of the
procedures described in Section 3.
 
  5. CERTAIN UNITED STATES FEDERAL INCOME TAX CONSEQUENCES. Sales of Shares
pursuant to the Offer (and the receipt of the right to receive cash by
stockholders of the Company pursuant to the Merger) will be taxable
transactions for Federal income tax purposes under the Internal Revenue Code
of 1986, as amended (the "Code"), and may also be taxable transactions under
applicable state, local, foreign and other tax laws, For Federal income tax
purposes, a tendering stockholder will generally recognize gain or loss equal
to the difference between the amount of cash received by the stockholder
pursuant to the Offer (or to be received pursuant to the Merger) and the
aggregate tax basis in the Shares tendered by the stockholder and purchased
pursuant to the Offer (or cancelled pursuant to the Merger). Gain or loss will
be calculated separately for each block of Shares tendered and purchased
pursuant to the Offer (or cancelled pursuant to the Merger). If tendered
Shares are held by a tendering stockholder as capital assets, gain or loss
recognized by the tendering stockholder will be capital gain or loss, which
will be long-term capital gain or loss if the tendering stockholder's holding
period for the Shares exceeds one year. However, for favorable long-term
capital gains tax treatment generally such tendering stockholder must have
held such Shares for in excess of 18 months.
 
  A stockholder (other than certain exempt stockholders including, among
others, all corporations and certain foreign individuals) that tenders Shares
may be subject to 31% backup withholding unless the stockholder provides its
TIN and certifies that such number is correct or properly certifies that it is
awaiting a TIN. A stockholder that does not furnish its TIN may be subject to
a penalty imposed by the IRS. Each stockholder should complete and sign the
Substitute Form W-9 included as part of the Letter of Transmittal so as to
provide the information and certification necessary to avoid backup
withholding.
 
 
                                      10
<PAGE>
 
  If backup withholding applies to a stockholder, the Depositary is required
to withhold 31% from payments to such stockholder. Backup withholding is not
an additional tax. Rather, the amount of the backup withholding can be
credited against the Federal income tax liability of the person subject to the
backup withholding, provided that the required information is given to the
IRS. If backup withholding results in an overpayment of tax, a refund can be
obtained by the stockholder upon filing an income tax return.
 
  THE FOREGOING DISCUSSION OF UNITED STATES FEDERAL INCOME TAX CONSEQUENCES IS
FOR GENERAL INFORMATION ONLY AND IS BASED ON EXISTING LAW AS OF THE DATE OF
THIS OFFER TO PURCHASE. THIS DISCUSSION MAY NOT BE APPLICABLE WITH RESPECT TO
SHARES RECEIVED PURSUANT TO THE EXERCISE OF EMPLOYEE STOCK OPTIONS OR
OTHERWISE AS COMPENSATION OR WITH RESPECT TO HOLDERS OF SHARES WHO ARE SUBJECT
TO SPECIAL TAX TREATMENT UNDER THE CODE, SUCH AS NON-U.S. PERSONS, LIFE
INSURANCE COMPANIES, TAX-EXEMPT ORGANIZATIONS AND FINANCIAL INSTITUTIONS.
STOCKHOLDERS OF THE COMPANY ARE URGED TO CONSULT THEIR OWN TAX ADVISORS TO
DETERMINE THE PARTICULAR TAX CONSEQUENCES TO THEM OF THE OFFER AND THE MERGER
(INCLUDING THE APPLICABILITY AND EFFECT OF FEDERAL, STATE, LOCAL, FOREIGN AND
OTHER TAX LAWS, AND POSSIBLE CHANGES IN SUCH TAX LAWS, WHICH MAY HAVE
RETROACTIVE EFFECT).

  On June 12, 1998, the last full trading day prior to the announcement of the
execution of the Merger Agreement, the last reported sales price of the Shares
on the Nasdaq National Market was $43.750 per Share. On June 17, 1998, the
last reported sales price of the Shares on the Nasdaq National Market was
$54.813 per Share. STOCKHOLDERS ARE URGED TO OBTAIN A CURRENT MARKET QUOTATION
FOR THE SHARES.
 
  The Company has not declared or paid any cash dividends on the Shares to
date and does not plan to pay cash dividends to its stockholders in the
future. Both the Company's existing bank facility and the indenture relating
to the Company's 10 1/2% Senior Notes due 2003 restrict the Company from
paying cash dividends to its stockholders, and there are also restrictions on
the ability of the Company's operating subsidiaries to pay dividends to the
Company. In addition, under the terms of the Merger Agreement, the Company is
not permitted to declare or pay dividends with respect to the Shares without
the prior written consent of Parent.

  7. EFFECT OF THE OFFER ON THE MARKET FOR THE SHARES; EXCHANGE ACT
REGISTRATION; MARGIN REGULATIONS.
 
  Market for the Shares. The purchase of Shares pursuant to the Offer will
reduce the number of holders of Shares and the number of Shares that might
otherwise trade publicly and could adversely affect the liquidity and market
value of the remaining Shares held by the public.
 
  Depending upon the number of Shares purchased pursuant to the Offer, the
Shares may no longer meet the standards of the National Association of
Securities Dealers, Inc. (the "NASD") for continued inclusion in the Nasdaq
National Market (the top tier market of the Nasdaq Stock Market), which
require that an issuer have at least 200,000 publicly held shares with a
market value of $1 million held by at least 400 stockholders (or 300
stockholders holding round lots) and having net tangible assets of at least $1
million, $2 million or $4 million depending on profitability levels during the
issuer's four most recent fiscal years. If these standards are not met, the
Shares might nevertheless continue to be included in the NASD's Nasdaq
National Market with quotations published in the Nasdaq "additional list" or
in one of the "local lists." However, if the number of holders of Shares falls
below 300, or if the number of publicly held Shares falls below 100,000, or if
there are not at least two market makers for Shares, NASD rules provide that
the Shares would no longer be "qualified" for Nasdaq Stock Market reporting,
and the Nasdaq Stock Market would cease to provide any quotations. Shares held
directly or indirectly by an officer or director of the Company, or by any
beneficial owner of more than 10% of the Shares, ordinarily will not be
considered as being publicly held for this purpose. According to the Company,
as of June 9, 1998, there were approximately 2,400 holders of record of Shares
and approximately 14,766,575 Shares were outstanding. If, as a result of the
purchase of Shares pursuant to the Offer or otherwise, the Shares no longer
meet the NASD requirements for continued inclusion in any tier of the Nasdaq
National Market or in any other tier of the Nasdaq Stock Market, and the
Shares are no longer included in any tier of the Nasdaq National Market, the
market for such Shares could be adversely affected.
 
  In the event the Common Stock no longer meets the requirements of the NASD
for inclusion in any tier of the Nasdaq Stock Market, quotations might still
be available from other sources. The extent of the public market for Common
Stock and availability of such quotations would depend, however, upon the
number of holders of Common Stock remaining at such time, the interest in
maintaining a market in the Common Stock on the part of securities firms, the
possible termination of registration under the Exchange Act, as described
below, and other factors.
 
  Exchange Act Registration. The Shares currently are 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 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 statement pursuant
to Section 14(a) 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. If registration of the
Shares under the Exchange Act were terminated, the Shares would no longer be
"margin securities" or be eligible for Nasdaq reporting. The Purchaser intends
to seek to cause the Company to apply for termination of registration of the
Common Stock under the Exchange Act as soon after the completion of the Offer
as the requirements for such termination are met.
 
  If registration of the Common Stock is not terminated prior to the Merger,
then the Common Stock will be delisted from all stock exchanges and the
registration of the Common Stock under the Exchange Act will be terminated
following the consummation of the proposed Merger.
 
                                      12
<PAGE>
 
  Margin Regulations. The Shares are currently "margin securities" under the
regulations of the Board of Governors of the Federal Reserve System (the
"Federal Reserve Board"), which has the effect, among other things, of
allowing brokers to extend credit on the collateral of the Shares. Depending
upon factors similar to those described above regarding listing and market
quotations, it is possible that, following the Offer, shares of the Common
Stock would no longer constitute "margin securities" for the purposes of the
margin regulations of the Federal Reserve Board and therefore could no longer
be used as collateral for loans made by brokers.

  Other Financial Information. During the course of discussions between Parent
and the Company, the Company provided Parent with certain estimates showing
estimated earnings per share for the Company of $2.18, $3.68, $4.39 and $5.31
for the fiscal years 1998, 1999, 2000 and 2001, respectively. In addition, the
Company provided Parent with certain additional estimates of the Company's
projected revenues and net income through the Company's fiscal year 2001. The
Company does not as a matter of course make public any estimates as to future
performance or earnings, and the estimates set forth above are included in
this Offer to Purchase only because the information was provided to Parent.
The estimates were not prepared with a view to public disclosure or compliance
with the published guidelines of the Commission or the guidelines established
by the American Institute of Certified Public Accountants regarding
projections or forecasts. The foregoing information is "forward-looking" and
inherently subject to significant uncertainties and contingencies, many of
which are beyond the control of the Company, including industry performance,
general business and economic conditions, changing competition, adverse
changes in applicable laws, regulations or rules governing environmental, tax
or accounting matters and other matters. The estimates were based on a number
of assumptions, some of which inevitably will prove to be incorrect. None of
the Company, the Purchaser or Parent or their respective advisers assumes any
responsibility for the accuracy of any of the estimates. The inclusion of the
foregoing estimates should not be regarded as an indication that the Company,
the Purchaser, Parent or any other person who received such information
considers it an accurate prediction of future events. Neither the Company nor
Parent intends to update, revise or correct such estimates if they become
inaccurate (even in the short term).

  10. SOURCE AND AMOUNT OF FUNDS. The Purchaser estimates that the total
amount of funds required to acquire the outstanding Shares pursuant to the
Offer, consummate the Merger, and to pay related fees and expenses will be
approximately $908.1 million (or approximately $1.18 billion including the
repayment of approximately $269 million of the Company's outstanding
indebtedness (including the amount required to fund the Change of Control
Offer (as defined below))). See Sections 12 and 16. The Offer is not
conditioned upon any financing arrangements. Purchaser expects to obtain the
funds required to consummate the Offer through capital contributions or
advances made by Parent.
 
  Parent expects to fund the Offer and the Merger through the use of a
combination of (i) internally generated funds and (ii) borrowings under (x) a
$300 million existing credit facility (the "Existing Credit Facility") and (y)
a new $1 billion credit facility (the "New Facility") to be provided by Morgan
Guaranty Trust Company of New York, Bank of America NT&SA and The Chase
Manhattan Bank (collectively, the "Lenders").
 
  Existing Credit Facility. Pursuant to a $300 million Credit Agreement, dated
as of February 7, 1995, among Parent, Morgan Guaranty Trust Company of New
York, as Agent, and the other banks that are parties thereto, as amended (the
"Credit Agreement") Parent may borrow up to an aggregate of $300 million for
general corporate purposes on a revolving basis. As of June 16, 1998, Parent
had no outstanding indebtedness under the Credit Agreement. The Credit
Agreement expires April 9, 2001. Loans under the Credit Agreement generally
bear interest on the unpaid principal at [a rate per annum equal to the higher
of (i) the prime rate described therein and (ii) the sum of 1/2 of 1% plus the
federal funds rate. The covenants contained in the Credit Agreement include a
minimum consolidated net worth test.
 
  New Facility. Pursuant to a bank commitment letter dated June 5, 1998 among
Parent and the Lenders (the "Bank Commitment Letter"), the Lenders each have
committed (the "Commitments") to provide up to approximately $333 million
(and, collectively $1 billion in the aggregate) to fund the Offer and the
Merger and related expenses, and for general corporate purposes.
 
  The Bank Commitment Letter provides that the New Facility will be
established as a 364-day fully revolving credit facility. Loans will bear
interest at rates based on the London interbank offered rate ("LIBOR") plus a
facility fee and LIBOR margin based fee on the total outstanding indebtedness
of Parent and its direct and indirect subsidiaries and the rating of Parent's
senior unsecured long-term debt (including the Company and including
indebtedness under the New Facility). The margin will range from 0.225% per
year to 0.55%.
 
  The covenants will include a minimum consolidated net worth test. Parent has
agreed to pay underwriting, agency and other fees to J.P. Morgan Securities
Inc. ("JPMSI") and the Lenders or their affiliates and to pay certain other of
its and their expenses. Parent has also agreed to indemnify JPMSI and the
Lenders, their respective affiliates and their respective directors, officers
and employees against certain types of losses and liabilities arising out of
the commitment or the New Facility.
 
  The Commitments made by the Lenders are subject to the satisfaction of
certain conditions including the following: (i) certain representations from
Parent; (ii) the continued credit rating of Parent following the consummation
of the transactions contemplated by the Merger Agreement; (iii) absence of
material adverse
 
                                      17
<PAGE>
 
changes in the financial condition, business, assets, results of operations or
prospects of Parent or its subsidiaries or the Company; (iv) Lenders'
satisfaction that, except as otherwise agreed, prior to and during any
syndication of the New Facility there shall be no competing offer, placement
or arrangement of debt securities or bank financing on behalf of Parent; (v)
absence of adverse changes in the syndicated loan markets generally or in the
regulatory environment that in the Lenders' reasonable judgment are likely to
materially and adversely affect the syndication of the New Facility; and (vi)
the negotiation and execution of definitive documentation with respect to the
New Facility.
 
  The foregoing summary description of the Bank Commitment Letter does not
purport to be complete. There is no assurance that the terms described below
will be contained in the definitive documentation for the New Facility, and
additional terms may be included. If for any reason the New Facility is not
finalized or does not become available, Parent would require alternative
funding which it would seek from other sources. Those sources might include
bank borrowings or sales of debt or equity securities in the capital markets.
 
  It is anticipated that the indebtedness incurred by Parent in connection
with the Offer and the Merger will be repaid from funds generated internally
by Parent and its subsidiaries (including, after the Merger, if consummated,
funds generated by the surviving corporation and its subsidiaries), proceeds
of dispositions, through other sources which may include the proceeds of
future bank refinancings, dispositions or the public or private sale of debt
or equity securities, or through a combination of two or more such sources. No
final decisions have been made, however, concerning the method Parent will
employ to repay such indebtedness. Such decisions, when made, will be based on
Parent'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.
 
  11. BACKGROUND OF THE OFFER; CONTACTS WITH THE COMPANY.
 
  Parent and its affiliates have followed the business activities of the
Company for some time, and at various times over the past few years senior
executives of Parent have had discussions with the Company's senior executives
and representatives of principal stockholders regarding Parent's interest in
exploring a possible purchase of the Company.
 
  In February 1996, Frank A. Riddick, Parent's Senior Vice President and Chief
Financial Officer, contacted representatives of Oaktree Capital Management LLC
("Oaktree"), which represents certain entities holding approximately 35% (on a
fully-diluted basis) of the Company's outstanding capital stock, with a view
to discussing Parent's interest in the Company. Representatives of Oaktree
expressed that it was not interested at that time in exploring a sale of the
Company.
 
  On May 15, 1996, Mr. Riddick met with representatives of Oaktree. The
purpose of the meeting was to express Parent's interest in exploring a
possible purchase of the Company and to discuss valuations of the Company. Mr.
Riddick expressed Parent's willingness to pay $25 per share for the Company's
Common Stock. Oaktree indicated its belief that, as a result of business
opportunities that the Company was in the process of exploring, a per share
price in the $40 range would be more appropriate. No further discussions took
place.
 
  In January 1997, George A. Lorch, Parent's Chairman and Chief Executive
Officer called Floyd F. Sherman, the Company's Chairman and Chief Executive
Officer and met with him to discuss the possibility of a business combination
transaction.
 
  By letter dated January 29, 1997, Parent engaged J.P. Morgan Securities Inc.
("J.P. Morgan") to act as Parent's financial advisor with respect to the
possible acquisition by Parent of the Company.
 
  On March 20, 1997, Messrs. Lorch and Riddick and Robert J. Shannon,
President of Parent's Worldwide Floor Products Operations, met with Mr.
Sherman, M. Joseph McHugh (the Company's President and Chief Operating
Officer) and Robert Symon (the Company's Chief Financial Officer at that
time). The purpose of the meeting was to discuss the Company's business and
gather information with a view to making a potential offer for the Company.
Mr. Sherman expressed that if Parent wanted to make an offer, the Board of the
Company would consider it.
 
                                      18
<PAGE>
 
  By letter dated March 26, 1997 from Mr. Lorch to Mr. Sherman, Parent
submitted a preliminary non-binding proposal with respect to the acquisition
of all of the common stock of the Company at a price of $32.00 per share
through an all cash tender offer that would not be contingent upon financing.
 
  By letter dated April 7, 1997 from Mr. Sherman to Mr. Lorch, Mr. Sherman
advised that Parent's unsolicited proposal was discussed with the directors of
the Company, that the Company was not for sale at that time and that the Board
had no interest in pursuing Parent's proposal.
 
  In late March or early April of 1998, a representative from Salomon, the
Company's financial advisor, called Parent to say that the Company would
likely be put up for sale through an auction process and that an invitation to
participate would be forthcoming.
 
  By letter dated March 25, 1998, Parent reaffirmed its engagement of J.P.
Morgan as its financial advisor with respect to the acquisition by Parent of
the Company.
 
  By letter dated April 6, 1998, Parent received an invitation from Salomon to
participate in a bidding process and to submit a preliminary indication of
interest relating to the acquisition of the Company. At that time Parent
received general information about the Company. In addition, on April 6, 1998,
Parent executed a confidentiality agreement with respect to the information to
be received regarding the Company.
 
  By letter dated April 24, 1998 to Salomon, Parent submitted a preliminary
non-binding indication of interest with respect to a possible purchase of the
Company.
 
  In early May, Salomon notified Parent by telephone that Parent would be
included as one of the bidders in the auction process and Parent was invited
to conduct due diligence in late May.
 
  During May, Parent submitted due diligence requests for and received
information regarding the Company. On May 20 and May 21, 1998, Parent and its
financial and legal advisors conducted business and financial due diligence at
the offices of Salomon in New York, New York. During these due diligence
sessions, various documentary due diligence was conducted and members of the
Company's senior management team made presentations to prospective bidders.
 
  By letter dated May 22, 1998, Parent received bid instructions, as well as a
draft of the Merger Agreement.
 
  From May 26, 1998 through June 8, 1998, members of Parent's financial and
legal due diligence team conducted additional due diligence, including at the
offices of the Company's external auditors and legal advisors in Dallas,
Texas. In addition, during this period, members of Parent's senior management
and members of Parent's Board of Directors met with a representative of J.P.
Morgan, financial advisor to Parent, to discuss, among other things, valuation
of the Company, a possible merger and the conditions to the transaction.
 
  On June 3, 1998, the Board of Directors of Parent authorized and approved
the submission of a bid by Parent with respect to the Offer and the Merger,
approved and adopted, and authorized the execution and delivery of, the form
of Merger Agreement with such changes as necessary and appropriate and the
Stock Tender Agreement, and authorized and directed negotiations with respect
thereto.
 
  On June 5, 1998, Parent submitted its proposal to acquire Shares of the
Company's common stock at a price of $55.00 per Share in cash, subject to the
execution and delivery of the Stock Tender Agreement and the retention of
certain key employees of the Company. Parent's comments to the draft Merger
Agreement accompanied Parent's proposal.
 
  On June 8, 1998, Parent and J.P. Morgan were notified by representatives of
Salomon that Parent would be given an opportunity to conduct plant tours and
to meet with counsel to the Company to discuss the Merger Agreement.
 
  On June 9, 1998 meetings among the representatives of the Company, Parent
and the Purchaser were held during which negotiations on the Merger Agreement
were conducted and additional legal and financial due diligence regarding the
Company was conducted by Purchaser. Negotiations with respect to the Merger
Agreement addressed, among other things, the circumstances under which the
termination fee would be payable,
 
                                      19
<PAGE>
 
the amount of the termination fee, provisions imposing restrictions on the
Company's ability to enter into a competing transaction, representations and
warranties and the conditions to the Offer. On June 9 and 10, 1998, members of
Parent's due diligence team conducted additional due diligence at several of
the Company's plants.
 
  Parent was advised that the Board of Directors of the Company would analyze
various offers submitted by bidders with respect to the Company on June 10,
1998. On the morning of June 10, Parent had discussions with Messrs. Sherman
and McHugh and reached a general understanding regarding their respective
roles with the Company following consummation of the Merger. After the
Company's Board meeting, Salomon contacted J.P. Morgan to seek from Parent a
higher price and certain other modifications to the Merger Agreement.
 
  On June 11, 1998, members of senior management of Parent and the Company and
representatives of J.P. Morgan and Salomon had various discussions regarding
pricing and termination fees. At the end of such discussions Parent increased
its proposed per Share offer price to $55.50. Simultaneously with such
discussions, the negotiation of the Merger Agreement continued.
 
  On June 12, 1998, the Board of Directors of the Company unanimously (with
one member absent) approved the Offer, the Merger and the Merger Agreement
(subject to modifications by the appropriate officers of the Company), and
determined that the terms of the Offer, the Merger and the Merger Agreement
are fair to, and in the best interests of, the stockholders of the Company. In
addition, the Board of Directors of the Company determined to recommend that
stockholders of the Company accept the proposed Offer and tender their Shares
pursuant to the Offer. On June 12, 1998, Salomon delivered to the Board of
Directors of the Company its written opinion to the effect that, as of the
date thereof, the consideration to be received by the stockholders of the
Company in the Offer and the Merger, is fair, from a financial point of view,
to such stockholders.
 
  On June 12, 1998, the Company entered into the Merger Agreement and the
Stock Tender Parties entered into the Stock Tender Agreement with the
Purchaser and Parent.
 
  12. PURPOSE OF THE OFFER; PLANS FOR THE COMPANY; THE MERGER AGREEMENT; STOCK
TENDER AGREEMENT.
 
  Purpose. The purpose of the Offer is to enable Parent to acquire control of,
and the entire equity interest in, the Company. Following the Offer, Parent
and the Purchaser intend to acquire any remaining equity interests in the
Company not acquired in the Offer by consummating the Merger. Upon
consummation of the Merger, the Company will become a wholly-owned subsidiary
of Parent. Accordingly, the Shares will cease to be publicly traded and will
no longer be quoted on the Nasdaq National Market.
 
  Plans for the Company. It is expected that, initially following the Merger,
the business and operations of the Company will continue without substantial
change. 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 further actions as it deems
appropriate under the circumstances then existing. Such actions could include
changes in the Company's business, corporate structure, certificate of
incorporation, by-laws, capitalization, Board of Directors, management or
dividend policy, although, except as disclosed in this Offer to Purchase,
Parent has no current plans with respect to any of such matters.
 
  The Merger Agreement provides that, commencing upon the purchase of Shares
pursuant to the Offer, and from time to time thereafter, Parent will be
entitled to designate directors to serve on the Board of Directors of the
Company as described below under "Merger Agreement--The Company's Board of
Directors." The Merger Agreement also provides that the directors of the
Purchaser at the Effective Time of the Merger will, from and after the
Effective Time, be the initial directors of the Company after the Merger.
 
  Upon consummation of the Merger, Parent may amend and restate the Company's
Certificate of Incorporation and by-laws to, among other things, provide for a
non-staggered board of directors and to otherwise amend or delete provisions
that will no longer be appropriate for a privately-held company.
 
                                      20
<PAGE>
 
  Simultaneously with or following the Merger, Parent may or may cause the
Company to refinance or repay approximately $269 million of outstanding
indebtedness under its existing credit facility (including amounts required
for the Change of Control Offer described below).
 
  Pursuant to the Indenture dated as of August 1, 1993 between the Company, as
issuer, and First Trust National Association, as trustee, relating to the
Company's 10 1/2% Senior Notes due 2003 (the "Senior Notes"), following the
acquisition by Parent or the Purchaser of beneficial ownership of more than
50% of the Shares, the Company will be required to make an offer (the "Change
of Control Offer") to holders of such Senior Notes to repurchase the Senior
Notes at a purchase price in cash in an amount equal to 101% of the principal
amount of such Senior Notes, plus accrued and unpaid interest thereon, if any,
to the purchase date thereof and to repurchase such Senior Notes within 40
business days after the acquisition of such Shares.
 
  George A. Lorch, Chairman and Chief Executive Officer of Armstrong and Frank
A. Riddick, Chief Financial Officer of Armstrong, have had discussions with
Floyd F. Sherman, Chairman of the Board and Chief Executive Officer of the
Company, and Joseph McHugh, President of the Company, concerning the roles
Messrs. Sherman and McHugh will play following the consummation of the offer.
They have reached an understanding that, following receipt of certain payments
due to them upon a voluntary termination following a change of control,
Messrs. Sherman and McHugh will remain with the Company, for a one-year
period, most likely in their current or similar positions and will not compete
with or select employees for a one-year period after their employment. It is
anticipated that Mr. Sherman also will become President of Parent's wood
flooring and cabinet operations. Mr. McHugh expects to retire approximately
one year after the transaction.
 
  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 and a copy of which
has been filed with the Commission as an exhibit to the Schedule 14D-1. The
Merger Agreement may be examined and copies may be obtained at the place and
in the manner set forth in Section 8, "Available Information," of this Offer
to Purchase.
 
  The Offer. The Merger Agreement provides that the Purchaser will commence
the Offer and that, upon the terms and subject to the prior satisfaction or
waiver of the Offer Conditions (which are set forth in Section 14), the
Purchaser will purchase all Shares validly tendered pursuant to the Offer. The
Merger Agreement provides that the Purchaser may modify and extend the terms
of the Offer as described in Section 1. Subject to the terms and conditions of
the Offer, the Purchaser shall pay, as soon as reasonably practicable after it
is permitted to do so under applicable law, for all Shares validly tendered
and not withdrawn. See Section 4.
 
  The Merger. The Merger Agreement provides that, subject to the terms and
conditions thereof, and in accordance with Delaware law, the Purchaser will be
merged with and into the Company as soon as practicable after satisfaction or
waiver of the conditions set forth in the Merger Agreement (the "Effective
Time"), with the Company continuing as the surviving corporation in the Merger
(the "Surviving Corporation"). In the Merger, each issued and outstanding
Share (other than Shares owned directly or indirectly by the Parent, Purchaser
or any of their subsidiaries or by the Company as treasury stock and Shares
the holder of which has perfected appraisal rights under the DGCL) will be
converted into the right to receive $55.50 per Share, without interest.
 
  The Merger Agreement provides that the certificate of incorporation and
bylaws of the Company at the Effective Time will be the certificate of
incorporation and bylaws of the Surviving Corporation until thereafter amended
as provided by law. The Merger Agreement provides that the directors of the
Purchaser at the Effective Time will be the directors of the Surviving
Corporation, and the officers of the Company at the Effective Time will be the
officers of the Surviving Corporation.
 
  The Company's Board of Directors. The Merger Agreement provides that,
commencing upon the purchase of Shares pursuant to the Offer, and from time to
time thereafter, Parent will be entitled to designate such number of
directors, rounded up to the next whole number, on the Board of Directors of
the Company as is equal to the product of (i) the total number of directors on
the Board (giving effect to any directors elected as described in
 
                                      21
<PAGE>
 
this sentence) and (ii) the percentage that (A) the aggregate number of shares
of Common Stock beneficially owned by Purchaser or any of its affiliates
(including Shares accepted for payment in the Offer, provided funds therefor
have been deposited with the Depositary) is to (B) the total number of Shares
then outstanding. The Company has agreed to take any and all actions within
the Company's power necessary to cause the Purchaser's designees to be
appointed to the Company's Board of Directors (including by increasing the
size of such Board using its best efforts to cause incumbent directors to
resign). The Company also has agreed to use its best efforts to cause persons
designated by the Purchaser to constitute the same percentage of each
committee of the Board of Directors of the Company, each board of directors of
each subsidiary of the Company and each committee of each such board as such
persons represent on the Board of Directors of the Company. In the Merger
Agreement, the Company has agreed to mail to the Company's stockholders an
Information Statement containing the information required by Section 14(f) of
the Exchange Act and Rule 14f-1 promulgated thereunder, and, if necessary,
seeking the resignation of one or more existing directors. However, the Merger
Agreement further provides that until the Effective Time, the Company will
retain as members of its Board of Directors at least two directors who are
directors of the Company at the date of the Merger Agreement ("Company
Designees"). The Merger Agreement also provides that following the time that
the Purchaser's designees to the Company's Board of Directors constitute a
majority of the Board, any amendment of the Merger Agreement, any termination
of the Merger Agreement by the Company, any extension of time for performance
of any of the obligations of the Purchaser or Parent under the Merger
Agreement, any waiver of any condition to the obligations of the Company or of
any of the Company's rights under the Merger Agreement or other action by the
Company under the Merger Agreement may be effected only by the action of a
majority of the Company Designees, provided that if there shall be no such
Company Designees, such actions may be effected by unanimous vote of the
entire Board of Directors.
 
  Company Stock Options. Pursuant to the Merger Agreement, all outstanding
options held by all current and former employees and directors of the Company
to purchase Common Stock (the "Company Stock Options") granted under any
employee stock option or compensation plan or arrangement of the Company (the
"Company Stock Plans"), whether or not then exercisable, will be made fully
vested and exercisable and cancelled by the Company immediately before the
earlier of (i) the consummation of the Offer or (ii) the Effective Time, and
thereafter, each holder's sole right shall be to, and each holder will, be
paid by the Company for each Share subject to such Company Stock Option an
amount in cash (subject to any applicable withholding taxes) equal to the
difference between the Offer Price and the exercise price per share of such
Company Stock Option, which amount shall be paid by the Company at the time
such Company Stock Option is cancelled. The Company will use its best efforts
to obtain any necessary consents and make any amendments to the terms of the
Company Stock Plans to the extent such consents or amendments are necessary to
give effect to the foregoing. Prior to the Effective Time the Company Stock
Plans will be terminated and provisions in any other benefit plan providing
for the issuance or grant of any other interest in respect of the Company's
capital stock or any subsidiary shall be deleted. In addition, upon
consummation of the Offer, Parent has agreed to make a loan to the Company, on
commercially reasonable terms, in an amount sufficient for the Company to make
payments to the holders of the Company Stock Options, or, if such amount
cannot be borrowed by the Company for any reason, to contribute such amount to
the Company.
 
  Warrants. Pursuant to the Merger Agreement, all outstanding Warrants of the
Company (other than the Bank Warrants (as defined below) which shall be
treated as described herein, and Warrants owned by Parent, the Purchaser or
any other direct or indirect subsidiary of Parent, which Warrants shall be
cancelled and extinguished at the Effective Time, with no payment being made
with respect to such Warrants) shall, following the Effective Time, be
exercisable only for an amount in cash equal to the product of (i) the number
of Shares issuable upon exercise of such Warrant and (ii) the difference
between the Offer Price and the per Share exercise price per Warrant, without
interest, which amount shall be paid from and after the Effective Time upon
surrender to the paying agent for the Offering of the warrant certificates for
cancellation. The Company has agreed to take all actions necessary to ensure
that following the Effective Time the Warrants shall represent only the right
to receive the consideration specified in the preceding sentence, all
agreements with respect to the Warrants shall be terminated and cancelled and
no party to such Warrant agreements shall have the right to acquire any
capital
 
                                      22
<PAGE>
 
stock of the Company, Parent, the Surviving Corporation or any of their
respective subsidiaries. In addition, with respect to certain rights held by
certain banks and other financial institutions (the "Bank Warrants") entitling
them to receive an aggregate of not more than 4,858 Shares (upon payment of
$.01 per Share) upon the exercise of the Warrants described above, the Company
has agreed to use its best efforts to (i) obtain prior to the Effective Time,
consents or waivers from each bank and financial institution whereby such
institutions agree to receive, upon presentment of their Bank Warrants, cash
equal to the product of (x) the number of Shares issuable upon exercise of
such Bank Warrant and (y) the difference between the Offer Price and the per
Share exercise price per Bank Warrant, without interest, (ii) ensure that
following the Effective Time (A) the Bank Warrants shall represent only the
right to receive cash in an amount equal to the per share Offer Price less
$.01 per Share, (B) the agreement with respect to the Bank Warrants is
terminated and cancelled and (C) no party to such agreements shall have the
right to acquire any capital stock of the Company, Parent, the Surviving
Corporation or any of their respective subsidiaries.
 
  Approval Required; Stockholders Meeting. The DGCL requires, among other
things, that the adoption of any plan of merger or consolidation of the
Company must be approved by the Board of Directors of the Company and, if the
"short form" merger procedure described below is not available, by the holders
of a majority of the Company's outstanding Shares. The Board of Directors of
the Company has approved the Offer, the Merger and the Merger Agreement;
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. Under the DGCL, the
affirmative vote of holders of a majority of the outstanding Shares (including
any Shares owned by the Purchaser), is generally required to approve the
Merger. If the Purchaser acquires, through the Offer or otherwise, voting
power with respect to at least a majority of the outstanding shares, it would
have sufficient voting power to effect the Merger without the vote of any
other stockholder of the Company. However, the DGCL also provides that if a
parent company owns at least 90% of each class of stock of a subsidiary, the
parent company can effect a short-form merger with that subsidiary without the
action of the other stockholders of the subsidiary. Accordingly, if, as a
result of the Offer or otherwise, the Purchaser acquires or controls the
voting power of at least 90% of the outstanding Shares, the Purchaser could
(and, under the Merger Agreement, is required to) effect the Merger using the
"short-form" merger procedures without prior notice to, or any action by, any
other stockholder of the Company.
 
  Pursuant to the Merger Agreement, the Company will, if required by
applicable law in order to consummate the Merger, duly call and hold a special
meeting of its stockholders (the "Special Meeting") as soon as practicable
following the consummation of the Offer, for the purpose of voting upon the
Merger and the adoption of the Merger Agreement. The Merger Agreement provides
that in connection with the Special Meeting, the Company will (i) as soon as
reasonably practicable after the consummation of the Offer, prepare and file
with the Commission a proxy statement and other proxy materials relating to
the Merger and the Merger Agreement and (ii) use its best efforts to have such
proxy statement and any supplement or amendment thereto cleared by the
Commission. If the Purchaser acquires at least a majority of the outstanding
Shares, the Purchaser will have sufficient voting power to approve the Merger,
even if no other stockholder votes in favor of the Merger. The Company has
agreed, subject to its fiduciary duties under applicable law, to include in
the proxy statement the recommendation of the Board of Directors that
stockholders of the Company vote in favor of the approval of the Merger and
the adoption of the Merger Agreement.
 
  Interim Operations. The Company has agreed that during the period from the
date of the Merger Agreement until the Effective Time (except as expressly
permitted by the Merger Agreement or as otherwise indicated, or as required by
a governmental entity or agreed to in writing by Parent) the business of the
Company and its subsidiaries shall be conducted only in the ordinary course in
all material respects, in substantially the same manner as previously
conducted and the Company and its subsidiaries will use reasonable efforts to
preserve intact their present lines of business and keep available the
services of their current officers and employees and preserve their
relationships with customers, suppliers, licensors, licensees, distributors,
and others
 
                                      23

having business dealings with them. In addition, subject to the exceptions
described above, each of the Company and its subsidiaries will not:
 
    (i) (x) declare or pay any dividends on, or make any other distributions
  (whether in stock, cash or property) in respect of, any of its capital
  stock, except dividends by a wholly owned direct or indirect subsidiary of
  the Company to such subsidiary's parent, (y) split, combine or reclassify
  any of its capital stock or issue or authorize or propose the issuance of
  any other securities in respect of, in lieu of or in substitution for,
  shares of its capital stock, except for any such transaction by a wholly
  owned subsidiary of the Company which remains a wholly owned subsidiary
  after consummation of such transaction, or (z) repurchase, redeem or
  otherwise acquire any shares of capital stock or any securities convertible
  into or exercisable for any shares of its capital stock except to the
  extent required under the Company's employment agreements;
 
    (ii) issue, deliver, sell, pledge or otherwise encumber any shares of its
  capital stock or authorize or propose the issuance, delivery, sale, pledge
  or encumbrance of, any shares of its capital stock of any class, any
  Company voting debt instruments (collectively, "Company Voting Debt"), or
  any securities convertible into or exercisable for, or any rights, warrants
  or options to acquire, any such shares or Company Voting Debt, or enter
  into any agreement with respect to the foregoing, other than (A) the
  issuance of Common Stock upon the exercise of stock options of the Company
  outstanding on the date of the Merger Agreement in accordance with their
  present terms or upon the exercise of Warrants or (B) issuances by a wholly
  owned subsidiary of the Company of capital stock to such subsidiary's
  parent;
 
    (iii) except to the extent required to comply with its obligations under
  the Merger Agreement, required by law or required by the rules and
  regulations of the Nasdaq National Market, amend their respective
  certificates of incorporation, bylaws or other governing documents;
 
    (iv) acquire or agree to acquire by merging or consolidating with, or by
  purchasing a substantial equity interest in or substantial portion of the
  assets of, or by any other manner, any business or any corporation,
  partnership, association or other business organization or division thereof
  or otherwise acquire or agree to acquire any assets (other than the
  acquisition of assets used in the operations of the business of the Company
  and its subsidiaries in the ordinary course); provided, however, that the
  foregoing shall not prohibit (A) internal reorganizations or consolidations
  involving existing wholly owned subsidiaries of the Company or (B) the
  creation of new subsidiaries of the Company organized to conduct or
  continue activities otherwise permitted by the Merger Agreement that in the
  case of clause (A) or (B) would not otherwise be prohibited by or result in
  a breach of these provisions. Other than (x) internal reorganizations or
  consolidations involving existing wholly owned subsidiaries of the Company
  and (y) as may be required by or in conformance with law or regulation in
  order to permit or facilitate the transactions contemplated by the Merger
  Agreement, the Company shall not, and shall not permit any wholly owned
  subsidiary of the Company to, sell, lease, encumber or otherwise dispose
  of, or agree to sell, lease, encumber or otherwise dispose of, any of its
  assets (including capital stock of wholly owned subsidiaries of the
  Company) which are material, individually or in the aggregate, to the
  Company other than sales of inventory in the ordinary course of business.
 
    (v) (A) create, assume or incur any indebtedness, guarantee or endorse
  any such indebtedness of another person, issue any debt securities,
  warrants or other rights to acquire any debt securities of the Company or
  any of its Subsidiaries, or guarantee any debt securities of another
  person, other than indebtedness incurred under the Company's existing
  credit agreement or other indebtedness in an aggregate amount not to exceed
  $500,000, (B) except in the ordinary course of business consistent with
  past practice make any loans, advances or capital contributions to, or
  investments in, any other person, other than by the Company or a wholly
  owned subsidiary of the Company to or in the Company or any wholly owned
  subsidiary of the Company or (C) except in the ordinary course of business
  consistent with past practice pay, discharge or satisfy any claims,
  liabilities or obligations (absolute, accrued, asserted or unasserted,
  contingent or otherwise), provided, however, that the Company may refinance
  indebtedness under its existing credit agreement;
 
 
                                      24
<PAGE>
 
    (vi) other than in accordance with the provisions of the Merger Agreement
  and unless required by law or to maintain the tax qualification of any
  Company benefit plan, (A) increase any employee benefits provided to, or,
  except in the ordinary course of business consistent with past practices,
  increase the compensation or fringe benefits payable to, any employee or
  former employee of the Company or any subsidiary of the Company, (B) adopt,
  enter into, terminate or amend in any material respect any employment
  contract, collective bargaining agreement or Company benefit plan; (C) pay
  any benefit not provided for under any Company benefit plan or any other
  benefit plan or arrangement of the Company and its subsidiaries; or (D)
  increase in any manner the severance or termination pay of any officer or
  employee;
 
    (vii) change its methods of accounting in effect as December 31, 1997,
  except as required by changes in U.S. generally accepted accounting
  principles as concurred in by the Company's independent auditors;
 
    (viii) enter into any agreement of a nature that would be required to be
  filed as an exhibit to Form 10-K under the Exchange Act, other than
  contracts for the sale of the Company's or its subsidiaries' products in
  the ordinary course of business; or
 
    (ix) knowingly take any actions that would make any representation or
  warranty of the Company contained in the Merger Agreement untrue or
  incorrect in any material respect as of the date when made or as of the
  closing date of the Merger;
 
    (x) authorize any of, or commit to agree to take any of the foregoing
  actions.
 
  Employee Benefits. Parent has agreed to cause the Surviving Corporation to
maintain until December 31, 1999 employee benefit plans or policies (other
than those based on shares of Common Stock) for the benefit of the employees
of the Company and its subsidiaries (other than those employees who are
employed pursuant to a collective bargaining agreement or who are members of a
collective bargaining unit or labor union) which are substantially comparable
in the aggregate to the employee benefit plans of the Company in effect on the
date of the Merger Agreement (other than stock-based plans or stock-based
provisions in the plans). The Company's employees shall be given credit, for
purposes of any service requirements for participation in the Parent employee
benefit plans for which they become eligible, if any, for their period of
service with the Company prior to the Effective Time. Parent has acknowledged
that the transactions contemplated by the Merger Agreement will constitute a
change of control under certain employment agreements and accordingly require
certain payments thereunder.
 
  No Solicitations. In the Merger Agreement, the Company has agreed that,
except as provided below, until the earlier of the termination of the Merger
Agreement or the Effective Date, neither the Company nor any of its
subsidiaries shall, and that it shall direct and use its reasonable best
efforts to cause its and its subsidiaries' directors, officers, employees,
agents and representatives (including any investment banker, attorney or
accountant retained by it or any of its subsidiaries) not to, directly or
indirectly, initiate, solicit, encourage or knowingly facilitate (including by
way of furnishing information) any inquiries or the making of any proposal or
offer with respect to a merger, reorganization, share exchange, consolidation,
business combination, recapitalization, liquidation, dissolution or similar
transaction involving, or any purchase or sale of all or a significant portion
of the assets of it or any of its subsidiaries or any purchase or sale of more
than 25% of the equity securities of the Company or any equity securities of
any Significant Subsidiary (as that term is defined in Rule 405 under the
Securities Act of 1933, as amended) (any such proposal or offer whether or not
in writing or in sufficient detail to be accepted and whether or not
conditional (other than a proposal or offer made by Parent or an affiliate
thereof) being hereinafter referred to as an "Acquisition Proposal"). In
addition, the Company agreed that neither it nor any of its subsidiaries
shall, and that it shall direct and use its reasonable best efforts to cause
its and its subsidiaries' directors, officers, employees, agents and
representatives (including any investment banker, attorney or accountant
retained by it or any of its subsidiaries) not to, directly or indirectly,
have any discussion with or provide any confidential information or data to
any person relating to an Acquisition Proposal, or engage in any negotiations
concerning an Acquisition Proposal, or knowingly facilitate any effort or
attempt
 
                                      25
<PAGE>
 
to make or implement an Acquisition Proposal or accept an Acquisition
Proposal. Notwithstanding the foregoing, the Company or its Board of Directors
is permitted to, at any time prior to the acceptance for payment of the Shares
pursuant to the Offer, (i) engage in discussions or negotiations with, or
provide information to, any person in response to an unsolicited Acquisition
Proposal by such person if (A) the Board of Directors of the Company concludes
in good faith that such Acquisition Proposal constitutes or could reasonably
be expected to lead to a Superior Proposal (as defined below) and (B), before
providing any information to such person, the Board of Directors receives from
such person an executed confidentiality agreement; and (ii) if the Board of
Directors concludes in good faith that such unsolicited Acquisition Proposal
constitutes a Superior Proposal (x) recommend approval of such Superior
Proposal, (y) in response to such Superior Proposal, withdraw or modify in an
adverse manner the approval of the Company's Board of Directors, or (z) enter
into an agreement in principle or a definitive agreement with respect to such
Superior Proposal, provided, however, that, in the case of either (i) or (ii)
the Board of Directors of the Company determines in good faith after
consultation with outside counsel that it should take such action consistent
with its fiduciary duties under applicable law. The Company has agreed to (i)
notify Parent promptly after receipt of any Acquisition Proposal (or any
indication that any person is considering making an Acquisition Proposal) or
any decision to provide non-public information relating to the Company or any
of its subsidiaries to any person that may be considering making, or has made,
an Acquisition Proposal, including a description of the material terms
thereof. For the purposes hereof, a "Superior Proposal" means a bona fide
unsolicited Acquisition Proposal which the Company's Board of Directors
concludes in good faith (after consultation with its financial advisors and
legal counsel), taking into account all legal, financial, regulatory and other
aspects of the proposal and the person making the proposal, provides for a
transaction that, taking into account its likelihood of completion, is more
favorable to the Company's stockholders (in their capacity as stockholders),
than the transactions contemplated by the Merger Agreement.
 
  Directors' and Officers' Insurance; Indemnification. The Merger Agreement
provides that until the expiration of all applicable statutes of limitations,
from and after the consummation of the Offer, the Company shall and Parent
shall cause the Company to, and from and after the Effective Time, Parent and
Surviving Corporation (each, an "Indemnifying Party") shall indemnify, defend
and hold harmless the present and former officers and directors of the Company
and its subsidiaries ("Indemnified Parties") against all losses, claims,
damages, liabilities, fees, penalties and expenses (including reasonable fees
and disbursements of counsel and judgments, fines, losses, claims, liabilities
and amounts paid in settlement arising out of actions or omissions occurring
at or before the consummation of the Offer) (including losses incurred in
connection with such person's serving as a trustee or other fiduciary in any
entity if such service was at the request or for the benefit of the Company or
any of its subsidiaries), to the fullest extent permitted by Delaware law,
such right to include the right to advancement of expenses incurred in the
defense of any action or suit promptly after statements therefor are received
to the fullest extent permitted by law; provided that the Indemnified Party to
whom expenses are advanced provides an undertaking to repay such advance if it
is ultimately determined that such party is not entitled to indemnification.
Notwithstanding the foregoing, an Indemnifying Party shall not be liable for
any settlement of any claim effected without such Indemnifying Party's written
consent, which consent shall not be unreasonably withheld.
 
  The Merger Agreement also provides that the Surviving Corporation shall
until the sixth anniversary of the Effective Time, cause to be maintained in
effect, to the extent available, the policies of directors' and officers'
liability insurance maintained by the Company and its subsidiaries as of the
date of the Merger Agreement (or policies of at least the same coverage and
amounts containing terms that are no less favorable to the insured parties),
in each case including for claims arising from facts or events that occurred
at or before the consummation of the Offer. In addition, the Merger Agreement
provides that the provisions relating to indemnification contained in the
Company's certificate of incorporation and bylaws (and following the Effective
Time, the Surviving Corporation) will not for a period of ten years following
the Effective Time, be amended, repealed or otherwise modified in any manner
that would adversely affect the rights thereunder of individuals who on or
before the consummation of the Offer were entitled to advances,
indemnification or exculpation thereunder.

  Conditions to the Merger. The Merger Agreement provides that the respective
obligations of the Company, Parent and the Purchaser to consummate the Merger
are subject to the satisfaction or waiver of the following conditions: (i) no
laws shall have been adopted or promulgated, and no temporary restraining
order, preliminary or permanent injunction or other order issued by a court or
governmental entity of competent jurisdiction shall be in effect, having the
effect of making the Merger illegal or otherwise prohibiting consummation of
the Merger; (ii) any applicable waiting period (and any extension thereof)
under the HSR Act relating to the Merger shall have expired or been
terminated; (iii) Parent, the Purchaser or their affiliates shall have
purchased Shares pursuant to the Offer; and (iv) the Merger Agreement having
been adopted by the requisite vote of the stockholders of the Company, if
required by applicable law, in order to consummate the Merger. In addition,
the obligations of (A) Parent and the Purchaser to consummate the Merger are
subject to the satisfaction or waiver of the following additional conditions:
(x) each of the representations and warranties of the Company contained in the
Merger Agreement being true and correct on the closing date of the Merger; and
(y) performance or compliance in all material respects with all agreements and
covenants required to be performed by the Company under the Merger Agreement
at or before the closing of the Merger and (B) the Company to consummate the
Merger are subject to the satisfaction or waiver of the following additional
conditions: (1) each of the representations and warranties of Parent and the
Purchaser contained in the Merger Agreement being true and correct on the
closing date of the Merger and (2) performance or compliance in all material
respects with all agreements and covenants required to be performed by Parent
and the Purchaser under the Merger Agreement at or before the closing of the
Merger.
 
  Representations and Warranties. In the Merger Agreement, the Company has
made customary representations and warranties to Parent and the Purchaser with
respect to, among other things, its organization, capitalization, financial
statements, public filings, conduct of business, compliance with laws,
litigation, title to property, non-contravention, consents and approvals,
opinions of financial advisors, undisclosed liabilities and the absence of
certain changes with respect to the Company since January 2, 1998.
 
  Termination; Fees. The Merger Agreement may be terminated at any time prior
to the Effective Time, whether before or after approval by the stockholders of
the Company: (i) by the mutual written consent of the Company and Parent, by
action of their respective boards of directors; (ii) by either of the Company,
on the one hand, or Parent and Merger Sub, on the other hand (A) if Shares
shall not have been purchased pursuant to the Offer on or before the Extension
Date, (B) if any governmental entity shall have issued an order, decree or
ruling or taken any other action (which order, decree, ruling or other action
the parties shall use their respective reasonable best efforts to lift), in
each case permanently restraining, enjoining or otherwise prohibiting the
transactions contemplated by the Merger Agreement, and such order, decree,
ruling or other action shall have become final and nonappealable, (C) if, due
to the failure of one of the Offer Conditions (other than the condition set
forth in paragraph (g) of Section 14) to occur, Parent, the Purchaser or any
of their affiliates shall have failed to commence the Offer on or before five
business days following the date of the initial public announcement of the
Offer or (D) if, due to a failure of any of the Offer Conditions, the Offer is
terminated or expires in accordance with its terms and the terms of the Merger
Agreement without Parent or Merger Sub, as the case may be, purchasing any
Shares thereunder; (iii) by the Company (A) if, before the purchase of Shares
pursuant to the Offer, the Board of Directors either shall (x) have entered
into an agreement with respect to a Superior Proposal, (y) have recommended a
Superior Proposal or (z) have withdrawn or modified in an adverse manner to
Parent or the Purchaser its approval or recommendation of the Offer, this
Agreement or the Merger (or the Board of Directors resolves to do any of the
foregoing) or (B) if Parent or the Purchaser shall have terminated the Offer,
or the Offer shall have expired in accordance with its terms and the terms of
the Merger Agreement without Parent or the Purchaser, as the case may be,
purchasing any Shares pursuant thereto; (iv) by Parent and the Purchaser if,
before the purchase of Shares pursuant to the Offer, the Board of Directors of
the Company shall (A) have recommended an Acquisition Proposal, (B) have
withdrawn or modified in a manner adverse to Parent or Merger Sub its approval
or recommendation of the Offer, the Merger Agreement or the Merger or (C) have
executed an agreement in principle or definitive agreement relating to an
Acquisition Proposal or similar business combination with a person other than
Parent, the Purchaser or their affiliates (or the Board of Directors of the
Company resolves to do any of the foregoing).
 
                                      27
<PAGE>
 
  In the event that (i) the Company terminates the Merger Agreement pursuant
to clause (iii)(A) of the previous paragraph, or if Parent terminates the
Merger Agreement pursuant to clause (iv) of the previous paragraph or (ii) the
Merger Agreement is terminated for any other reason (other than the breach of
this Agreement by Parent or the Purchaser and other than by mutual agreement
of the parties thereto) and, in the case of this clause (ii) only, (A) at the
time of such termination there was pending an Acquisition Proposal from a
third party and (B) the transactions contemplated by such Acquisition Proposal
with such third party are consummated with such third party within one year
after such termination, then the Company shall pay to Parent a termination fee
in an amount equal to $28 million.
 
  Credit Agreement. In connection with the Credit Agreement, the Company has
agreed to use its best efforts to obtain all necessary waivers and consents
prior to the consummation of the Offer so that the transactions contemplated
by the Merger Agreement will not result in or constitute a default under the
Credit Agreement. In the event that (i) such waivers and consents are not
obtained; (ii) the transactions contemplated by the Merger Agreement result in
a default under the Credit Agreement and the lenders thereunder accelerate the
payment of outstanding indebtedness thereunder; and (iii) the Company, after
using its best efforts, is unable to refinance or repay such indebtedness,
then, Parent has agreed following the consummation of the Offer, to make a
loan to the Company in an amount sufficient for the Company to repay the
outstanding indebtedness under the Credit Agreement and any other obligations
under the Credit Agreement, or, if such amount cannot be borrowed by the
Company for any reason, to contribute such amount to the Company.
 
  Fees and Expenses. The Merger Agreement provides that, except as provided
above under "Termination; Fees", all expenses incurred in connection with the
Merger Agreement and the transactions contemplated thereby will be paid by the
party incurring such expenses, except (i) if the Merger is consummated, the
Surviving Corporation shall pay, or cause to be paid, any and all property or
transfer taxes imposed on the Company or its subsidiaries; (ii) expenses
incurred in connection with the filing, printing and mailing of the Offer
materials, the Schedule 14D-9 and, if required, the Proxy Statement, which
shall be shared equally by Parent and the Company; and (iii) amounts loaned or
contributed by Parent to the Company as described herein, shall be repaid by
the Company or the Surviving Corporation, as the case may be, on commercially
reasonable terms.
 
  Stock Tender Agreement. The following is a summary of the material terms of
the Stock Tender Agreement. This summary is qualified in its entirety by
reference to the Stock Tender Agreement which is incorporated herein by
reference, a copy of which has been filed with the Commission as an exhibit to
the Schedule 14D-1. The Stock Tender Agreement may be examined and copies may
be obtained at the place and in the manner as set forth in Section 8 of this
Offer to Purchase.
 
  After the execution of the Merger Agreement, the Purchaser, Parent and the
Stock Tender Parties entered into the Stock Tender Agreement. Pursuant to such
Agreement, so long as the Company, Parent or the Purchaser has not terminated
the Merger Agreement, the Stock Tender Parties have agreed to validly tender
(and not thereafter withdraw) the Shares owned by them pursuant to and in
accordance with the terms of the Offer. As of June 9, 1998, the Stock Tender
Parties owned a total of 5,909,184 Shares, representing approximately 35% of
the outstanding Shares calculated on a fully diluted basis.
 
  In connection with the Stock Tender Agreement, the Stock Tender Parties have
made certain customary representations, warranties and covenants, including
with respect to (i) ownership of the Shares, (ii) the Stock Tender Parties'
authority to enter into and perform their respective obligations under the
Stock Tender Agreement, (iii) the ability of the Stock Tender Parties to enter
into the Stock Tender Agreement without violating other agreements to which
they are party, (iv) the absence of liens and encumbrances on and in respect
of the Stock Tender Parties' Shares and (v) restrictions on the transfer of
the Stock Tender Parties' Shares.
 
  13. DIVIDENDS AND DISTRIBUTIONS. As described above, the Merger Agreement
provides that, prior to the Effective Time, the Company and each of its
subsidiaries will not (i) declare or pay any dividend on or make other
distributions (whether in stock, cash or property) in respect of any of its
capital stock, except dividends by a wholly owned direct or indirect
subsidiary of the Company to such subsidiary's parent, (ii) split, combine or
 
                                      28
<PAGE>
 
reclassify any of its capital stock or issue or authorize or propose the
issuance of any other securities in respect of, in lieu of or in substitution
for, shares of its capital stock, except for any such transaction by a wholly
owned subsidiary of the Company which remains a wholly owned subsidiary after
consummation of such transaction, or (iii) repurchase, redeem or otherwise
acquire any shares of capital stock or any securities convertible into or
exercisable for any shares of its capital stock.
 
  If, on or after the date of the Merger Agreement, the Company should (i)
split, combine or otherwise change the Shares or its capitalization, (ii)
issue or sell, or enter into any arrangement or contract with respect to the
issuance or sale of, any additional securities (including rights, options or
warrants, conditional or otherwise) of the Company or otherwise cause an
increase in the number of outstanding securities (including rights, options or
warrants, conditional or otherwise) of the Company, or (iii) acquire currently
outstanding Shares or otherwise cause a reduction in the number of outstanding
Shares, then, subject to the provisions of Section 14, the Purchaser, in its
sole judgment, may make such adjustments in the Offer Price and the other
terms of the Offer as it deems appropriate in the Offer Price and other terms
of the Offer (including, without limitation, the number and type of securities
offered to be purchased, the amounts payable therefor and the fees payable
hereunder).
 
  If, on or after the date of the Merger Agreement, the Company should declare
or pay any cash or stock dividend or other distribution (including the
issuance of any securities) on or issue any rights with respect to the Shares
payable or distributable to stockholders of record on a date before the
transfer to the name of the Purchaser or its nominee or transferee on the
Company's stock transfer records of the Shares accepted for payment pursuant
to the Offer, then, subject to the provisions of Section 14, (i) the Offer
Price payable by the Purchaser pursuant to the Offer may, in the sole
discretion of the Purchaser, be reduced by the amount of any such cash
dividend or cash distribution and (ii) the whole of any such non-cash
dividend, distribution or right (a) will be received and held by the tendering
stockholder for the account of the Purchaser and shall be required to be
promptly remitted and transferred by each tendering stockholder to the
Depositary for the account of the Purchaser, accompanied by appropriate
documentation of transfer and (b) at the direction of the Purchaser, will be
exercised for the benefit of the Purchaser, in which case the proceeds of such
exercise will be remitted promptly to the Purchaser. Pending such remittance
and subject to applicable law, the Purchaser will be entitled to all rights
and privileges as owner of any such non-cash dividend, distribution or right
and may withhold the entire purchase price or deduct from the purchase price
the amount or value thereof, as determined by the Purchaser, in its sole
discretion.
 
  Pursuant to the terms of the Merger Agreement, the Company is prohibited
from taking any of the actions described in the preceding paragraphs and
nothing herein shall constitute a waiver by the Purchaser or Parent of any of
its rights under the Merger Agreement or a limitation of remedies available to
the Purchase or Parent for any breach of the Merger Agreement, including
termination thereof.
 
  14. CERTAIN CONDITIONS OF THE OFFER. Notwithstanding any other provisions of
the Offer, and in addition to (and not in limitation of) the Purchaser's
rights pursuant to the Merger Agreement to extend and amend the Offer at any
time, in its sole discretion, the Purchaser shall not be required to accept
for payment or, subject to any applicable rules and regulations of the
Commission, including Rule 14e-1(c) under the Exchange Act (relating to the
Purchaser'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 the restriction referred to above, the payment
for, any tendered Shares, and may terminate the Offer, if, in the sole
judgment of the Purchaser (i) any applicable waiting period under the HSR Act
has not expired or been terminated, (ii) the Minimum Condition has not been
satisfied or (iii) at any time on or after the date of this Offer to Purchase
and before the time of acceptance of Shares for payment pursuant to the Offer,
any of the following events shall occur:
 
    (a) there shall have been any statute, rule, regulation, judgment,
  decision, action, order or injunction promulgated, entered, enforced,
  enacted or issued applicable to the Offer or the Merger by any federal or
  state governmental regulatory or administrative agency or authority or
  court or legislative body or commission that (1) prohibits the consummation
  of the Offer or the Merger, (2) prohibits Parent's or the
 
                                      29
<PAGE>
 
  Purchaser's ownership or operation of all or a majority of the Company's
  businesses or assets, or imposes any material limitations on Parent's or
  the Purchaser's ownership or operation of all or a majority of the
  Company's businesses or assets or would have a material adverse effect on
  the Company and its subsidiaries taken as a whole or (3) imposes material
  limitations on the ability of Parent or Merger Sub to acquire or hold, or
  exercise full rights of ownership of, any Shares to be accepted for payment
  pursuant to the Offer including, without limitation, the right to vote such
  Shares on all matters properly presented to the stockholders of the Company
  or any federal or state governmental regulatory or administrative agency or
  authority shall have commenced or threatened to commence litigation or
  another proceeding intended to achieve the results set forth in clauses (1)
  through (3) above; provided, that the parties shall have used their
  reasonable best efforts to cause any such statute, rule, regulation,
  judgment, order or injunction to be vacated or lifted;
 
    (b) (1) the representations and warranties of the Company set forth in
  the Merger Agreement shall not be true and accurate as of the date of the
  Merger Agreement and at the scheduled or extended expiration of the Offer
  (except for those representations and warranties that address matters only
  as of a particular date or only with respect to a specified period of time
  which need only be true and accurate as of such date or with respect to
  such time period), except where the failure of such representations or
  warranties to be true and accurate, individually or in the aggregate, does
  not have a material adverse effect on the Company and its subsidiaries
  taken as a whole or (2) the Company shall have breached or failed to
  perform or comply in any material respect with any covenant required by the
  Merger Agreement to be performed or complied with by it;
 
    (c) the Merger Agreement shall have been terminated in accordance with
  its terms;
 
    (d) it shall have been publicly disclosed that any person, entity or
  "group" (as defined in Section 13(d)(3) of the Exchange Act) shall have
  acquired beneficial ownership (as determined pursuant to Rule 13d-3
  promulgated under the Exchange Act) of more than a majority of the then-
  outstanding Shares, through the acquisition of stock, the formation of a
  group or otherwise;
 
    (e) the Board of Directors of the Company (or any committee thereof)
  shall have withdrawn or modified in a manner adverse to Parent or Merger
  Sub its approval or recommendation of the Offer or the Merger or the
  adoption of the Merger Agreement or recommended an Acquisition Proposal
  other than the one contemplated by the Merger Agreement, or shall have
  executed an agreement in principle or a definitive agreement relating to
  such an Acquisition Proposal or similar business combination with a person
  or entity other than Parent, the Purchaser or their affiliates, or the
  Board of Directors of the Company shall have adopted a resolution to do the
  foregoing;
 
    (f) there shall have occurred and be continuing (1) any general
  suspension of trading of securities on any national securities exchange or
  in the over-the-counter market, (2) the declaration of a banking moratorium
  or any suspension of payments in respect of banks in the United States
  (whether or not mandatory) or (3) any limitation (whether or not mandatory)
  by a United States governmental authority or agency on the extension of
  credit by banks or other financial institutions which in the reasonable
  judgment of Parent or the Purchaser, in any such case, makes it inadvisable
  to proceed with the Offer or with such acceptance for payment or payments;
 
    (g) all consents, registrations, approvals, permits, authorizations,
  notices, reports or other filings required to be obtained or made by the
  Company, Parent or the Purchaser with or from any governmental entity in
  connection with the execution, delivery and performance of the Merger
  Agreement, the Offer and the consummation of the transactions contemplated
  by the Merger Agreement shall not have been made or obtained and such
  failure is reasonably likely to have a material adverse effect on the
  Company and its subsidiaries taken as a whole or; or
 
    (h) any change shall have occurred since the date of the Merger Agreement
  that individually or in the aggregate constitutes a material adverse effect
  on the Company and its subsidiaries taken as a whole.
 
 
                                      30

  The Merger Agreement provides that the foregoing conditions are for the sole
benefit of the Purchaser and Parent and may be asserted by Parent and the
Purchaser, in their sole discretion, regardless of the circumstances
(including any action or omission by Parent or the Purchaser) giving rise to
any such conditions and (except for the Minimum Condition, which may be waived
only with the consent of the Company) may be waived by Parent or the
Purchaser, in their sole discretion, in whole or in part, at any time and from
time to time, subject to the terms of the Merger Agreement. The failure by the
Parent or the 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. Any determination by the Purchaser concerning any condition or event
described in this Section 14 shall be final and binding upon all parties.
 
  15. CERTAIN LEGAL MATTERS; REGULATORY APPROVALS.
 
  Stockholder Litigation. On June 15, 1998, a purported class action lawsuit
was initiated in the Court of Chancery of Delaware by Pinna Yosevitz, who
purports to bring the action individually and on behalf of other stockholders
of the Company similarly situated against the Company, its directors and
Parent. The lawsuit is styled Pinna Yosevitz v. Floyd F. Sherman et. al.
(C.A.No.164474-NC) and seeks, among other things, a preliminary and permanent
injunction against the Offer and the Merger, rescission of the Offer and the
Merger if they are consummated, and compensatory damages. The complaint
asserts, among other things, that (i) the terms of the proposed Merger and
Offer were not the result of an auction process or active market check and
were arrived at without a full and thorough investigation by the individual
defendants and are intrinsically unfair and inadequate from the stand point of
the Company's stockholders; (ii) the individual defendants failed to make an
informed decision , as no market check of the Company's value was obtained;
(iii) the individual defendants have violated their fiduciary duties owed to
the public stockholders of the Company; (iv) the stockholders of the Company
have not received and will not receive their fair proportion of the value of
the Company's assets and business, and will be prevented from obtaining fair
and adequate consideration for their Shares; and (v) the intrinsic value of
the Company is materially in excess of the Offer Price giving due
consideration to the anticipated operating results, net asset value, cash flow
and profitability of the Company. The complaint also alleges that the
individual defendants' fiduciary obligations under these circumstances require
them to (i) undertake an appropriate evaluation of the Company's net worth as
a merger/acquisition candidate; and (ii) engage in a meaningful auction with
third parties in an attempt to obtain the best value for the Company's public
stockholders.
 
  General. Except as otherwise disclosed herein, based on a review of publicly
available filings by the Company with the Commission, neither Parent nor the
Purchaser is aware of (i) 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 acquisition of Shares by the
Purchaser pursuant to the Offer or the Merger or (ii) any approval or other
action by any governmental, administrative or regulatory agency or authority,
domestic or foreign, that would be required for the acquisition or ownership
of Shares by the Purchaser as contemplated herein. Should any such approval or
other action be required, the Purchaser currently contemplates that such
approval or action would be sought, except as described below under "State
Takeover Statutes." While the Purchaser does not currently intend to delay the
acceptance for payment of Shares tendered pursuant to the Offer pending the
outcome of any such matter, there can be no assurance that any such approval
or action, if needed, would be obtained or would be obtained without
substantial conditions or that adverse consequences might not result to the
business of the Company, the Purchaser or that certain parts of the businesses
of the Company or the Purchaser might not have to be disposed of in the event
that such approvals were not obtained or any other actions were not taken. The
Purchaser's obligation under the Offer to accept for payment and pay for
Shares is subject to certain conditions. See Section 14.
 
  Antitrust Compliance. Under the HSR Act, and the rules that have been
promulgated by the FTC and the Antitrust Division, certain acquisition
transactions may not be consummated unless certain information has been
furnished to the Antitrust Division and the FTC and certain waiting period
requirements have been satisfied. The acquisition of Shares pursuant to the
Offer is subject to such requirements.
 
 
                                      31
<PAGE>
 
  A Notification and Report Form with respect to the Offer has been filed, and
the waiting period with respect to the Offer under the HSR Act will expire at
11:59 p.m., New York City time, on the fifteenth calendar day after such
filing, unless terminated prior thereto. Before such time, however, either the
FTC or the Antitrust Division may extend the waiting period by requesting
additional information or material from the Purchaser. If such request is
made, the waiting period will expire at 11:59 p.m., New York City time, on the
tenth calendar day after the Purchaser has substantially complied with such
request. Thereafter, the waiting period may be extended only by court order or
with the Purchaser's consent. 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.
 
  The Merger would not require an additional filing under the HSR Act if the
Purchaser owns 50% or more of the outstanding Shares at the time of the Merger
or if the Merger occurs within one year after the HSR Act waiting period
applicable to the Offer expires or is terminated. However, if the Offer is
withdrawn or if the filing relating to the Offer is withdrawn prior to the
expiration or termination of the 15-day waiting period relating to the Offer,
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 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, in which event, 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 by consent.
 
  The FTC and the Antitrust Division frequently review the legality under the
antitrust laws of transactions such as the proposed acquisition of Shares by
the Purchaser pursuant to the Offer. At any time before or after the purchase
of Shares pursuant to the Offer by the Purchaser, the FTC or the Antitrust
Division could take such action under the antitrust laws as it deems necessary
or desirable in the public interest, including seeking to enjoin the purchase
of Shares pursuant to the Offer or the consummation of the Merger or seeking
the divestiture of Shares purchased by the Purchaser or the divestiture of
substantial assets of Parent, the Company or their respective subsidiaries.
Private parties and state attorneys general may also bring legal action under
federal or state antitrust laws under certain circumstances. Based upon an
examination of information available to the Purchaser relating to the
businesses in which Parent, the Purchaser, the Company and their respective
subsidiaries are engaged, the Purchaser believes that the Offer will not
violate the antitrust laws. Nevertheless, there can be no assurance that a
challenge to the Offer on antitrust grounds will not be made or, if such a
challenge is made, what the result would be. See Section 14 for certain
conditions to the Offer.
 
  State Takeover Statutes. The Company is incorporated under the laws of
Delaware. Section 203 of the DGCL limits ability of a Delaware corporation to
engage in business combinations with "interested stockholders" (defined
generally as any beneficial owner of 15% or more of the outstanding voting
stock of the corporation) unless, among other things, the corporation's board
of directors has given its prior approval to either the business combination
or the transaction which resulted in the stockholder becoming an "interested
stockholder." Prior to the execution of the Merger Agreement, the Company's
Board of Directors approved the Stock Tender Agreement, Merger Agreement and
the Purchaser's acquisition of Shares pursuant to the Offer and, therefore,
Section 203 of the DGCL is inapplicable to the Stock Tender Agreements, the
Offer and the Merger.
 
  A number of other states throughout the United States have enacted takeover
statutes that purport, in varying degrees, to be applicable to attempts to
acquire securities of corporations that are incorporated or have assets,
stockholders, executive offices or places or business in such states. In Edgar
v. MITE Corp., the Supreme Court of the United States held that the Illinois
Business Takeover Act, which involved state securities laws that made the
takeover of certain corporations more difficult, imposed a substantial burden
on interstate commerce and therefore was unconstitutional. However, in CTS
Corp. v. Dynamics Corp. of America, the Supreme Court of the United States
held that a state may, as a matter of corporate law, and, in particular, those
laws concerning
 
                                      32
<PAGE>
 
corporate governance, constitutionally disqualify a potential acquiror from
voting on the affairs of a target corporation without prior approval of the
remaining stockholders; provided that such laws were applicable only under
certain conditions.
 
  Based on information supplied by the Company, the Purchaser does not believe
that any state takeover statutes outside of Delaware purport to apply to the
Offer or the Merger. Neither the Purchaser nor Parent 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 or the Merger and nothing in this Offer to
Purchase or any action taken in connection with the Offer or the Merger is
intended as a waiver of such right. If it is asserted that any state takeover
statute is applicable to the Offer or the Merger and if an appropriate court
does not determine that it is inapplicable or invalid as applied to the Offer
or the Merger, 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 be delayed in consummating the Offer or the Merger.
In such case, the Purchaser may not be obliged to accept for payment or pay
for any Shares tendered pursuant to the Offer.
 
  Appraisal Rights. No appraisal rights are available in connection with the
Offer. However, if the Merger is consummated, stockholders will have certain
rights under Delaware law 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, as of the day prior to the date
on which the stockholders vote was taken approving the Merger or similar
business combination (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, the
court is 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. 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 the same, more or less than the purchase price per Share in the Offer
or the Merger Consideration.
 
  In addition, several decisions by Delaware courts have held that, in certain
circumstances, a controlling stockholder of a company involved in a merger has
a fiduciary duty to other stockholders which requires that the merger be fair
to such other stockholders. In determining whether a merger is fair to
minority stockholders, Delaware courts have considered, among other things,
the type and amount of consideration to be received by the stockholders and
whether there was fair dealing among the parties. The Delaware Supreme Court
stated in Weinberger and Rabkin v. Philip A. Hunt Chemical Corp. that the
remedy ordinarily available to minority stockholders in a cash-out merger is
the right to appraisal described above. However, 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.
 
  "Going Private" Transactions. The Commission has adopted Rule 13e-3 under
the Exchange Act which is applicable to certain "going private" transactions
and which may under certain circumstances be applicable to the Merger or
another business combination following the purchase of Shares pursuant to the
Offer in which Purchaser seeks to acquire the remaining Shares not held by it.
Purchaser believes, however, that Rule 13e-3 will not 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

             FORMING PART OF THE TERMS AND CONDITIONS OF THE OFFER
 
  1. GUARANTEE OF SIGNATURES. No signature guarantee on this Letter of
Transmittal is required (i) if this Letter of Transmittal is signed by the
registered holder (which term, for purposes of this document, shall include
any participant in a Book-Entry Transfer Facility whose name appears on a
security position listing as the owner of Shares) of the Shares tendered
herewith, unless such holder has completed either the box entitled "Special
Delivery Instructions" or the box entitled "Special Payment Instructions" on
this Letter of Transmittal or (ii) if such Shares are tendered for the account
of a firm that is a bank, broker, dealer, credit union, savings association or
other entity which is a member in good standing of the Securities Transfer
Agent's Medallion Program (each, an "Eligible Institution"). In all other
cases, all signatures on this Letter of Transmittal must be guaranteed by an
Eligible Institution. See Instruction 5.

<PAGE>
 
  2. DELIVERY OF LETTER OF TRANSMITTAL AND CERTIFICATES. This Letter of
Transmittal is to be used either if Share Certificates are to be forwarded
herewith or, unless an Agent's Message (as defined below) is utilized, if
tenders are to be made pursuant to the procedures for tender by book-entry
transfer set forth in Section 3 of the Offer to Purchase. Share Certificates,
or timely confirmation (a "Book-Entry Confirmation") of a book-entry transfer
of such Shares into the Depositary's account at a Book-Entry Transfer
Facility, as well as this Letter of Transmittal (or a facsimile hereof),
properly completed and duly executed, with any required signature guarantees,
or an Agent's Message in the case of a book-entry delivery, and any other
documents required by this Letter of Transmittal, must be received by the
Depositary at one of its addresses set forth herein prior to the Expiration
Date. Stockholders whose Share Certificates are not immediately available or
who cannot deliver their Share Certificates and all other required documents
to the Depositary prior to the Expiration Date or who cannot complete the
procedures for delivery by book-entry transfer on a timely basis may tender
their Shares by properly completing and duly executing a Notice of Guaranteed
Delivery pursuant to the guaranteed delivery procedures set forth in Section 3
of the Offer to Purchase. Pursuant to such procedure (i) such tender must be
made by or through an Eligible Institution; (ii) a properly completed and duly
executed Notice of Guaranteed Delivery, substantially in the form made
available by the Purchaser, must be received by the Depositary on or prior to
the Expiration Date; and (iii) the Share Certificates (or a Book-Entry
Confirmation) representing all tendered Shares, in proper form for transfer,
together with a Letter of Transmittal (or a facsimile thereof), properly
completed and duly executed, with any required signature guarantees (or, in
the case of a book-entry delivery, an Agent's Message) and any other documents
required by this Letter of Transmittal, must be received by the Depositary
within three NASDAQ National Market System ("NASDAQ") trading days after the
date of execution of such Notice of Guaranteed Delivery, as provided in
Section 3 of the Offer to Purchase. If Share Certificates are forwarded
separately to the Depositary, a properly completed and duly executed Letter of
Transmittal (or facsimile thereof) must accompany each such delivery.
 
  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 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.
 
  THE METHOD OF DELIVERY OF SHARES, THIS LETTER OF TRANSMITTAL AND ALL OTHER
REQUIRED DOCUMENTS, INCLUDING DELIVERY THROUGH ANY BOOK-ENTRY TRANSFER
FACILITY, IS AT THE OPTION AND SOLE RISK OF THE TENDERING STOCKHOLDER AND THE
DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY RECEIVED BY THE DEPOSITARY
(INCLUDING, IN THE CASE OF A BOOK-ENTRY TRANSFER, BY BOOK ENTRY CONFIRMATION).
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.
 
  No alternative, conditional or contingent tenders will be accepted and no
fractional Shares will be purchased. All tendering stockholders, by execution
of this Letter of Transmittal or facsimile thereof, waive any right to receive
any notice of the acceptance of their Shares for payment.
 
  3. INADEQUATE SPACE. If the space provided herein is inadequate, the
certificate numbers and/or the number of Shares and any other required
information should be listed on a separate schedule attached hereto and
separately signed on each page thereof in the same manner as this Letter of
Transmittal is signed.
 
  4. PARTIAL TENDERS. (APPLICABLE TO CERTIFICATE STOCKHOLDERS ONLY) If fewer
than all the Shares evidenced by any certificate submitted are to be tendered,
fill in the number of Shares which are to be tendered in the box entitled
"Number of Shares Tendered." In such case, new Share Certificate(s) for the
remainder of the Shares that were evidenced by the old Share Certificate(s)
will be sent to the registered holder, unless otherwise provided in the
appropriate box marked "Special Payment Instructions" and/or "Special Delivery
 
                                       6
<PAGE>
 
Instructions" on this Letter of Transmittal, as soon as practicable after the
acceptance for payment of, and payment for, the Shares tendered herewith. All
Shares represented by certificates delivered to the Depositary will be deemed
to have been tendered unless otherwise indicated.
 
  5. SIGNATURES ON LETTER OF TRANSMITTAL, STOCK POWERS AND ENDORSEMENTS. If
this Letter of Transmittal is signed by the registered holder(s) of the Shares
tendered hereby, the signature(s) must correspond exactly with the name(s) as
written on the face of the Share Certificate(s) without alteration,
enlargement or any change whatsoever.
 
  If any of the Shares tendered hereby are owned of record by two or more
joint owners, all such owners must sign this Letter of Transmittal.
 
  If any tendered Shares are registered in different names on Share
Certificates, it will be necessary to complete, sign and submit as many
separate Letters of Transmittal as there are different registrations of Share
Certificates.
 
  If this Letter of Transmittal or any Share Certificates or stock powers are
signed by trustees, executors, administrators, guardians, attorneys-in-fact,
officers of corporations or others acting in a fiduciary or representative
capacity, such persons should so indicate when signing, and should submit
proper evidence satisfactory to the Purchaser of their authority to so act.
 
  When this Letter of Transmittal is signed by the registered owner(s) of the
Shares listed and transmitted hereby, no endorsements of Share Certificates or
separate stock powers are required unless payment is to be made to, or Share
Certificates for Shares not tendered or purchased are to be issued in, the
name of a person other than the registered owner(s). Signatures on such Share
Certificates or stock powers must be guaranteed by an Eligible Institution.
 
  If this Letter of Transmittal is signed by a person other than the
registered owner(s) of the Shares listed, the Share Certificates must be
endorsed or accompanied by appropriate stock powers, in either case signed
exactly as the name or names of the registered owner(s) appear(s) on the Share
Certificates. Signatures on such Share Certificates or stock powers must be
guaranteed by an Eligible Institution.
 
  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 purchased Shares to it or its order pursuant to
the Offer. If, however, payment of the purchase price is to be made to, or if
Share Certificates not tendered or purchased are to be registered in the name
of, any person other than the registered holder, or if tendered Share
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 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 is to be issued in
the name of and/or Share Certificates for unpurchased Shares are to be
returned to a person other than the signer of this Letter of Transmittal or if
a check is to be sent and/or such Share Certificates are to be returned to
someone other than the signer of this Letter of Transmittal or to an address
other than that shown on the front cover hereof, the appropriate boxes on this
Letter of Transmittal should be completed. Stockholders tendering Shares by
book-entry transfer may request that Shares not purchased be credited to such
account maintained at such Book-Entry Transfer Facility as such stockholder
may designate hereon. If no such instructions are given, such Shares not
purchased will be returned by crediting the account at the Book-Entry Transfer
Facility designated above. See Instruction 1.

  8. WAIVER OF CONDITIONS. The Purchaser reserves the absolute right in its
sole discretion to waive any of the specified conditions of the Offer, in
whole or in part, in the case of any Shares tendered.
 
  9. REQUESTS FOR ASSISTANCE OR ADDITIONAL COPIES. Questions and requests for
assistance or additional copies of the Offer to Purchase and this Letter of
Transmittal, the Notice of Guaranteed Delivery and the Guidelines for
Certification of Taxpayer Identification Number on Substitute Form W-9 may be
directed to the Information Agent at its address set forth below.
 
  10. 31% BACKUP WITHHOLDING; SUBSTITUTE FORM W-9. Under U.S. Federal income
tax law, a stockholder whose tendered Shares are accepted for payment is
required to provide the Depositary with such stockholder's correct taxpayer
identification number ("TIN") on Substitute Form W-9 below. If the Depositary
is not provided with the correct TIN, the Internal Revenue Service (the "IRS")
may subject the stockholder or other payee to a $50 penalty. In addition,
payments that are made to such stockholder or other payee with respect to
Shares purchased pursuant to the Offer may be subject to 31% backup
withholding.
 
  Certain stockholders (including, among others, all corporations and certain
foreign individuals) are not subject to these backup withholding and reporting
requirements. In order for a foreign individual to qualify as an exempt
recipient, the stockholder must submit a Form W-8, signed under penalties of
perjury, attesting to that individual's exempt status. A Form W-8 can be
obtained from the Depositary. See the enclosed "Guidelines for Certification
of Taxpayer Identification Number on Substitute Form W-9" for more
instructions.
 
  If backup withholding applies, the Depositary is required to withhold 31% of
any such payments made to the stockholder or other payee. Backup withholding
is not an additional tax. Rather, the tax liability of persons subject to
backup withholding will be reduced by the amount of tax withheld. If
withholding results in an overpayment of taxes, a refund may be obtained from
the IRS.
 
  The box in Part 3 of the Substitute Form W-9 may be checked if the tendering
stockholder has not been issued a TIN and has applied for a TIN or intends to
apply for a TIN in the near future. If the box in Part 3 is checked, the
stockholder or other payee must also complete the Certificate of Awaiting
Taxpayer Identification Number below in order to avoid backup withholding.
Notwithstanding that the box in Part 3 is checked and the Certificate of
Awaiting Taxpayer Identification Number is completed, the Depositary will
withhold 31% of all payments made prior to the time a properly certified TIN
is provided to the Depositary.
 
  The stockholder is required to give the Depositary the TIN (e.g., social
security number or employer identification number) of the record owner of the
Shares or of the last transferee appearing on the transfers attached to, or
endorsed on, the Shares. If the Shares are in more than one name or are not in
the name of the actual owner, consult the enclosed "Guidelines for
Certification of Taxpayer Identification Number on Substitute Form W-9" for
additional guidance on which number to report.
 
  11. LOST, DESTROYED OR STOLEN SHARE CERTIFICATES. If any Share
Certificate(s) has been lost, destroyed or stolen, the stockholder should
promptly notify the Depositary. The stockholder will then be instructed as to
the steps that must be taken in order to replace the Share Certificate(s).
This Letter of Transmittal and related documents cannot be processed until the
procedures for replacing lost or destroyed Share Certificates have been
followed.
 
IMPORTANT: THIS LETTER OF TRANSMITTAL (OR A FACSIMILE COPY THEREOF), TOGETHER
WITH ANY REQUIRED SIGNATURE GUARANTEES, OR, IN THE CASE OF A BOOK-ENTRY
TRANSFER, AN AGENT'S MESSAGE AND ANY OTHER REQUIRED DOCUMENTS MUST BE RECEIVED
BY THE DEPOSITARY ON OR PRIOR TO THE EXPIRATION DATE AND EITHER CERTIFICATES
FOR TENDERED SHARES MUST BE RECEIVED BY THE DEPOSITARY OR SHARES MUST BE
DELIVERED PURSUANT TO THE PROCEDURES FOR BOOK-ENTRY TRANSFER, IN EACH CASE
PRIOR TO THE EXPIRATION DATE, OR THE TENDERING STOCKHOLDER MUST COMPLY WITH
THE PROCEDURES FOR GUARANTEED DELIVERY.

OBTAINING A NUMBER

If you do not have a taxpayer identification number or you do not know your
number, obtain form SS-5, Application for a Social Security Number Card (for
resident individuals), Form SS-4, Application for Employer Identification Number
(for businesses and all other entities), or Form W-7 for International Taxpayer
Identification Number (for alien individuals required to file U.S. tax returns),
at an office of the Social Security Administration or the Internal Revenue
Service.

To complete Substitute Form W-9, if you do not have a taxpayer identification
number, write "Applied For" in the space for the taxpayer identification number
in Part I, sign and date the Form, and give it to the requester.  Generally, you
will then have 60 days to obtain a taxpayer identification number and furnish it
to the requester.  If the requester does not receive your taxpayer
identification number within 60 days, backup withholding, if applicable, will
begin and will continue until you furnish your taxpayer identification number to
the requester.

PAYEES EXEMPT FROM BACKUP WITHHOLDING
Payees specifically exempted from backup withholding on ALL payments include the
following:*
 . A corporation.
 . A financial institution.
 . An organization exempt from tax under section 501(a), or an individual
  retirement plan, or a custodial account under section 403(b)(7).
 . The United States or any agency or instrumentality thereof.
 . A state, the District of Columbia, a possession of the United States, or any
  political subdivision or instrumentality thereof.
 . A foreign government or a political subdivision, agency or instrumentality
  thereof.
 . An international organization or any agency or instrumentality thereof.
 . A registered dealer in securities or commodities registered in the United
  States or a possession of the United States.
 . A real estate investment trust.
 . A common trust fund operated by a bank under section 584(a).
 . An exempt charitable remainder trust, or a non-exempt trust described in
  section 4947(a)(1).
 . An entity registered at all times during the tax year under the Investment
  Company Act of 1940.
 . A foreign central bank of issue.
_____________________________
* Unless otherwise noted herein, all references below to section numbers or to
  regulations are references to the Internal Revenue Code and the regulations
  promulgated thereunder.

EXEMPT PAYEES DESCRIBED ABOVE SHOULD FILE A SUBSTITUTE FORM W-9 TO AVOID
POSSIBLE ERRONEOUS BACKUP WITHHOLDING.  FILE THIS FORM WITH THE PAYER, FURNISH
YOUR TAXPAYER IDENTIFICATION NUMBER, WRITE "EXEMPT" ON THE FACE OF THE FORM,
SIGN AND DATE THE FORM AND RETURN IT TO THE PAYER.

Certain payments other than interest, dividends and patronage dividends that are
not subject to information reporting are also not subject to backup withholding.
For details, see the regulations under sections 6041, 6041A(a), 6045, and 6050A.

PRIVACY ACT NOTICES.  Section 6109 requires most recipients of dividends,
interest or other payments to give taxpayer identification numbers to payers who
must report the payments to the IRS.  The IRS uses the numbers for
identification purposes and to help verify the accuracy of your tax return.
Payers must be given the numbers whether or not recipients are required to file
tax returns.  Payers must generally withhold 31% of taxable interest, dividends,
and certain other payments to a payee who does not furnish a taxpayer
identification number to a payer.  Certain penalties may also apply.

Payments of dividends and patronage dividends not generally subject to backup
withholding include the following:
 . Payments to nonresident aliens subject to withholding under section 1441.
 . Payments to partnerships not engaged in a trade or business in the United
  States and which have at least one nonresident partner.
 . Payments of patronage dividends where the amount received is not paid in
  money.
 . Payments made by certain foreign organizations.
 . Payments made to a nominee.

Payments of interest not generally subject to backup withholding include the
following:

 . Payments of interest on obligations issued by individuals.  NOTE:  You may be
  subject to backup withholding if (i) this interest is $600 or more, and (ii)
  the interest is paid in the course of the payer's trade or business and (iii)
  you have not provided your correct taxpayer identification number to the
  payer.

 . Payments of tax-exempt interest (including exempt-interest dividends under
  section 852).
 . Payments described in section 6049(b)(5) to non-resident aliens.
 . Payments on tax-free covenant bonds under section 1451.
 . Payments made by certain foreign organizations.
 . Payments made to a nominee.

PENALTIES

(1)  PENALTY FOR FAILURE TO FURNISH TAXPAYER IDENTIFICATION NUMBER. -- If you
fail to furnish your taxpayer identification number to a payer, you are subject
to a penalty of $50 for each such failure unless your failure is due to
reasonable cause and not to willful neglect.

(2)  CIVIL PENALTY FOR FALSE STATEMENTS 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.

(3)  CRIMINAL PENALTY FOR FALSIFYING INFORMATION. -- If you falsify
certifications or affirmations, you are subject to criminal penalties including
fines and/or imprisonment.

(4)  FAILURE TO REPORT CERTAIN DIVIDEND AND INTEREST PAYMENTS. -- If you fail to
include any portion of an includible payment for interest, dividends or
patronage dividends in gross income and such failure is due to negligence, a
penalty of 20% is imposed on any portion of any underpayment attributable to the
failure.

SERVICE.

ARMSTRONG WORLD INDUSTRIES TO ACQUIRE TRIANGLE PACIFIC CORP.  FOR $55.50 PER
SHARE IN TRANSACTION VALUED AT $890 MILLION
                                        
- --Transaction Will Make Armstrong the World Leader in Wood Flooring--
                                        
LANCASTER, PA, AND DALLAS, TX, JUNE 13, 1998 -- Armstrong World Industries,
Inc., (NYSE:ACK) and Triangle Pacific Corporation (NASDAQ:TRIP) announced today
that they have signed a definitive merger agreement for Armstrong to acquire all
the outstanding shares of Triangle Pacific Corporation at a price of $55.50 per
share, or a total of approximately $890 million in cash on a fully diluted
basis.  Triangle Pacific is the leading manufacturer of hardwood flooring
products and a substantial manufacturer of kitchen and bathroom cabinets.
Including the assumption of Triangle Pacific's net debt of about $260 million,
the total value of the transaction will be $1,150 million.

Following the combination and the completion of the pending acquisition of DLW,
Armstrong will become the world's leading manufacturer of hard surface flooring.

The transaction has been unanimously approved by the Boards of Directors of both
companies.  Armstrong will commence a cash tender offer for all outstanding
Triangle Pacific shares for $55.50 per share within five business days.  The
offer is contingent upon a majority of the shares on a fully diluted basis being
tendered and other customary conditions. Certain principal stockholders of
Triangle Pacific have agreed to tender their shares into the offer (representing
approximately 35% of Triangle Pacific's outstanding common stock on a fully
diluted basis).  The tender will be followed by a merger in which any untendered
shares will be converted into the right to receive the same price in cash.  The
agreement is not subject to any financing condition, and Armstrong has already
received bank commitments from J.P. Morgan, Chase Manhattan, and Bank of
America.

George A. Lorch, Chairman and Chief Executive Officer of Armstrong, said,
"Triangle Pacific is one of the best companies in the building materials
industry, and this acquisition will mark a major addition to Armstrong's core
flooring business.  Together with the announcement just last week of our
agreement to acquire DLW, the third largest flooring manufacturer in Europe,
Triangle Pacific will make Armstrong the preeminent manufacturer of flooring
products worldwide.  Importantly, both announcements reaffirm our commitment to
be a major force in the consolidating global building materials industry.

"Hardwood flooring comprises 7 percent of the U.S. flooring market and is one of
the most rapidly growing segments.  Hardwood flooring is increasingly being
chosen by residential purchasers willing to spend more in order to obtain wood
flooring's beauty and durability.  Triangle Pacific is clearly the leader in
this area, with its highly regarded brands, outstanding manufacturing
technology, low cost producer status, broad and innovative product line, and its
excellent reputation for value and service."

Triangle Pacific sells three types of flooring products--solid hardwood,
engineered hardwood, and laminate--which together account for approximately 72%
of its revenues. Its brands include Bruce, the leading name in hardwood
flooring, as well as Hartco, Robbins, Premier, and Traffic Zone. In total,
Triangle Pacific accounts for approximately 46% of the U.S. hardwood flooring

segment. Triangle Pacific is also a substantial manufacturer of cabinets for
kitchens and bathrooms, targeted primarily toward the relatively higher-end,
single-family and multi-family markets. Cabinets account for approximately 28%
of Triangle Pacific's revenues.

Lorch said, "Triangle Pacific has also been guided by an outstanding management
team, led by Floyd Sherman, and we are pleased that they will join the combined
company."

Mr. Sherman, current Chairman and CEO of Triangle Pacific, will play an
important role in developing and implementing the growth plan, and will become
President, Wood Flooring and Cabinet Operations at Armstrong, reporting directly
to Armstrong's Chairman and CEO.

Lorch continued, "The combination of Armstrong's and Triangle Pacific's
strengths will provide an excellent strategic platform for additional profitable
growth.  Armstrong will support Triangle Pacific's future growth consistent with
their current plans.  In addition, significant new growth opportunities exist in
the commercial and international markets, and we expect to capitalize on
Armstrong's existing presence in these markets.  Internationally, for example,
particularly in Europe, Canada and Japan, wood generally commands a much higher
share of the flooring market than in the U.S.

"In addition to the sales opportunities, we will also be able to achieve
significant cost savings in logistics and marketing in the combined company.
Armstrong plans to invest in brand development, capacity, technology, and new
products and systems to support the growth of wood flooring around the world,"
Lorch said.  While a coordinated approach to marketing wood and vinyl products
is envisioned, there are no plans to eliminate or change any brands or
distribution systems.

Floyd Sherman, Chairman of Triangle Pacific, said, "We are very pleased to have
entered into this agreement.  For our shareholders, it offers excellent value
and an attractive premium for their shares.  For Triangle employees, customers
and suppliers, it provides a strong future as part of the preeminent name in the
flooring industry, under a management that has been squarely focused on how to
make their company efficient, innovative and customer-driven."

Armstrong expects that the two recently announced acquisitions, Triangle Pacific
and DLW, will be modestly dilutive to earnings in 1998, but accretive beginning
in 1999.  The company also expects to earn in excess of its cost of capital on
both investments.

"We continue to transform Armstrong into a growth and results-oriented,
financially strong and highly efficient manufacturer and marketer of name
brands, offering around the globe the kinds of products and values that
customers want," Lorch concluded. Upon completion of the two transactions,
Armstrong will have total flooring sales of $2.1 billion, with about 57% in
vinyl, 23% in hardwood, 14% in European carpet, and 6% in linoleum. Consolidated
sales will be approximately $3.5 billion with about 60% in floor products.

In fiscal year 1997, Triangle Pacific had total revenues of $652.9 million.
Headquartered in Dallas, Texas, it has a total of 5,400 employees.  Flooring
products accounted for $469.1 million of 1997 sales, and have grown at a
compounded annual rate of 26% since 1991.  Net income in 1997 of $31.8 million
has grown at a compounded annual rate of 19% since 1994.  Triangle Pacific
manufactures all of its flooring products in the U.S. in 15 plants in 11
geographically diverse locations, except for its Coastal Woodlands branded
products which are imported from Indonesia, Traffic Zone laminate products which
are imported from Germany, and a very limited amount of teak parquet imported
from Thailand.  Imported products accounted for around 3% of total units sold in
1997.

Triangle Pacific's kitchen and bathroom cabinets are manufactured in
approximately 100 different styles and colors and marketed under the Bruce and
IXL brand names.   The company operates four cabinet manufacturing plants
throughout the U.S.  Sales in 1997 were $183.8 million, for a U.S. market share
of approximately 3%.

J.P. Morgan acted as financial advisor for Armstrong and Salomon Smith Barney
acted as financial advisor to Triangle Pacific in this transaction.

Armstrong World Industries is a global leader in the design, innovation and
manufacture of interior finishing solutions, most notably floors and ceilings.
It is also a world leader in the innovation and manufacture of pipe insulation,
gasket material and textile machine parts.  Based in Lancaster, PA, Armstrong
has approximately 10,600 employees worldwide.  In 1997 its net sales totaled
$2.2 billion.

This announcement is neither an offer to purchase nor a solicitation of an offer
to sell Shares. The Offer is made solely by the Offer to Purchase dated June 19,
1998, and the related Letter of Transmittal and is not being made to (nor will
tenders be accepted from or on behalf of) holders of Shares in any jurisdiction
in which the making of the Offer or the acceptance thereof would not be in

by

Sapling Acquisition, Inc.
a wholly-owned subsidiary
of

Armstrong WORLD INDUSTRIES, INC.

Sapling Acquisition, Inc., a Delaware corporation (the "Purchaser") and a 
wholly-owned subsidiary of Armstrong World Industries, Inc., a Pennsylvania
corporation ("Parent"), is offering to purchase all outstanding shares of common
stock, par value $.01 per share (the "Shares"), of Triangle Pacific Corp., a
Delaware corporation (the "Company"), at a price of $55.50 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 June 19, 1998 (the "Offer
to Purchase") and in the related Letter of Transmittal (which, together with any
supplements or amendments thereto, collectively constitute the "Offer").


The Offer is conditioned upon, among other things, (i) there being validly
tendered and not withdrawn prior to the expiration of the Offer such number of
Shares, which would constitute at least a majority of the outstanding Shares of
the Company (determined on a fully-diluted basis), (ii) 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, and (iii)
the satisfaction or waiver of certain conditions to the obligations of the
Purchaser and the Company to consummate the Offer and the transactions
contemplated by the Merger Agreement (as defined below).

The Offer is being made pursuant to an Agreement and Plan of Merger, dated as of
June 12, 1998 (the "Merger Agreement"), by and among Parent, the Purchaser and
the Company pursuant to which, following the consummation of the Offer,  the
Purchaser will be merged with and into the Company, with the Company surviving
the merger as a wholly-owned subsidiary of Parent (the "Merger"). On the
effective date of the Merger, each outstanding Share (other than Shares owned
directly or indirectly by the Parent, Purchaser, or any of their subsidiaries or
by the Company as treasury stock, or by stockholders, if any, who are entitled
to and who properly exercise dissenter's rights under Delaware Law) will be
converted into the right to receive $55.50 in cash, without interest.

Parent and Purchaser have also entered into a Stock Tender Agreement dated as of
June 12, 1998, with certain principal stockholders of the Company (the
"Stockholders"), pursuant to which each Stockholder has agreed to tender into
the Offer all the Shares that such Stockholder owns. These shares represent
approximately 35% of the outstanding Shares (determined on a fully-diluted
basis) as of June 9, 1998.

THE BOARD OF DIRECTORS OF THE COMPANY (THE "BOARD") HAS UNANIMOUSLY (WITH ONE
MEMBER BEING ABSENT) 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
STOCKHOLDERS OF THE COMPANY, AND UNANIMOUSLY RECOMMENDS THAT STOCKHOLDERS OF THE
COMPANY ACCEPT THE OFFER AND TENDER THEIR SHARES.
<PAGE>
 
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 properly withdrawn as, if and when 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 purchased pursuant to the Offer will
be made by deposit of the purchase price therefor with the Depositary, which
will act as agent for tendering shareholders for the purpose of receiving the
payment from the Purchaser and transmitting payment to tendering stockholders
whose Shares have been accepted for payment. In all cases, payment for Shares
purchased pursuant to the Offer will be made only after timely receipt by the
Depositary of (a) certificates representing shares (or a timely Book-Entry
Confirmation (as defined in the Offer to Purchase) with respect to such Shares)
into the account maintained by the Depositary at the Depositary Trust Company
(the "Book-Entry Transfer Facility"), pursuant to the procedures set forth in
Section 3 of the Offer to Purchase, (b) the Letter of Transmittal (or a
facsimile thereof), properly completed and duly executed, with any required
signature guarantees or an Agent's Message (as defined in the Purchase), in
connection with a book-entry delivery, and (c) any other documents required by
the Letter of Transmittal. Accordingly, payment may not be made to all tendering
stockholders at the same time depending upon when certificates for or Book-Entry
Confirmations into the Depositary's account at the Book-Entry Transfer Facility
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.

The term "Expiration Date" means 12:00 midnight, New York City time, on Friday,
July 17, 1998, unless and until the Purchaser, in its sole discretion but
subject to the terms of the Merger Agreement, shall have extended the period of
time during which the Offer is open, in which event the term "Expiration Date"
shall mean the latest time and date on which the Offer, as so extended by the
Purchaser, shall expire. The Purchaser expressly reserves the right, in its sole
discretion (but subject to the terms of the Merger Agreement), at any time or
from time to time, and regardless of whether or not any of the events set forth
in Section 14 of the Offer to Purchase shall have occurred, (i) to extend the
period of time during which the Offer is open and thereby delay acceptance for
payment of, and the payment for, any Shares, by giving oral or written notice of
such extension to the Depositary and (ii) to amend the Offer in any other
respect by giving oral or written notice of such amendment to the Depositary.
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. There can be no assurance that the Purchaser will exercise the
right to extend the Offer. Any such extension will be followed by a public
announcement thereof no later than 9:00 a.m., New York City time, on the next
business day after the previously scheduled Expiration Date. During any such
extension, all Shares previously tendered and not withdrawn will remain subject
to the Offer, subject to the right of a tendering stockholder to withdraw such
stockholder's Shares.

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 the
Expiration Date. For a withdrawal to be effective, a written 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 the Offer to Purchase and
must specify the name of the person having tendered the Shares to be withdrawn,
the number of Shares to be withdrawn and the name of the registered holder of
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 signature on
the notice of withdrawal must be guaranteed by an Eligible Institution. If
Shares have been delivered pursuant to the procedures 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 a the Book-Entry Transfer
Facility to be credited with the withdrawn Shares and otherwise comply with such
Book-Entry Transfer Facilitly's procedures. Withdrawals of tenders of Shares may
not be rescinded, and any Shares properly withdrawn will thereafter be deemed
not validly tendered for 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 the form and validity (including time of receipt) of notices of withdrawal
will be determined by the Purchaser, in is sole discretion, whose determination
will be final and binding.

The Offer to Purchase and the related Letter of Transmittal and other relevant
materials will be mailed to record holders of Shares and 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.

                          AGREEMENT AND PLAN OF MERGER


          AGREEMENT AND PLAN OF MERGER, dated as of June 12, 1998 (this
"AGREEMENT"), among TRIANGLE PACIFIC CORP., a Delaware corporation (the
"COMPANY"), ARMSTRONG WORLD INDUSTRIES, INC., a Pennsylvania corporation
("PARENT"), and SAPLING ACQUISITION, INC., a Delaware corporation and a direct
wholly owned subsidiary of Parent ("MERGER SUB").


                              W I T N E S S E T H:

          WHEREAS, the respective Boards of Directors of the Company, Parent and
Merger Sub have each approved, and deem it advisable and in the best interests
of their respective stockholders to consummate, the acquisition of the Company
by Parent and Merger Sub pursuant to the Offer (as defined herein) and the
merger of Merger Sub with and into the Company (the "MERGER") upon the terms and
subject to the conditions set forth herein; and

          WHEREAS, the Company, Parent and Merger Sub desire to make certain
representations, warranties, covenants and agreements in connection with the
transactions contemplated hereby and also to prescribe various conditions to the
transactions contemplated hereby.

          NOW, THEREFORE, in consideration of the foregoing and the respective
representations, warranties, covenants and agreements set forth herein, and
intending to be legally bound hereby, the parties hereto agree as follows:


                                   ARTICLE I

                              THE OFFER AND MERGER

          1.1  THE OFFER.  (a)  Provided that this Agreement shall not have been
               ---------                                                        
terminated in accordance with Section 7.1 and none of the events set forth in
Annex A hereto (other than the events set forth in clause (g) thereof) shall
have occurred or be continuing, as promptly as practicable (but in no event
later than five business days from the public announcement of the execution
hereof), Merger Sub shall commence (within the meaning of Rule 14d-2 under the
Securities Exchange Act of 1934, as amended (the "EXCHANGE ACT")) an offer (the
"OFFER") to purchase for cash all of the issued and outstanding shares of Common
Stock, par value $.01 per share (each a "SHARE" and, collectively, the "SHARES"
or the "COMPANY COMMON STOCK"), of the Company,  at a price of $55.50 per Share,
net to the seller in cash (such price, or such higher price per Share as may be
paid in the Offer, the "OFFER PRICE").  Merger Sub shall, on the terms and
subject only to the prior satisfaction or waiver of the conditions of the Offer
set forth in Annex A hereto (except that the Minimum Condition (as defined
herein) may not be waived by Parent or Merger Sub without the consent of the

                                       1
<PAGE>
 
Company), accept for payment and pay for Shares tendered as soon as it is
legally permitted to do so under applicable law.  The obligations of Merger Sub
to accept for payment and to pay for any and all Shares validly tendered on or
before the expiration of the Offer and not withdrawn shall be subject only to
(i) there being validly tendered and not withdrawn before the expiration of the
Offer, that number of Shares which, together with any Shares beneficially owned
by Parent or Merger Sub, represent at least a majority of the Shares outstanding
on a fully diluted basis (the "MINIMUM CONDITION") and (ii) the other conditions
set forth in Annex A hereto (the "ADDITIONAL CONDITIONS" and, together with the
Minimum Condition, the "OFFER CONDITIONS").  The Offer shall be made by means of
an offer to purchase (the "OFFER TO PURCHASE") containing the terms set forth in
this Agreement and the Offer Conditions.  Merger Sub shall not amend or waive
the Minimum Condition and shall not decrease the Offer Price or decrease the
number of Shares sought, or amend any other term or condition of the Offer in
any manner adverse to the holders of the Shares or, except as provided in the
next two sentences, extend the expiration date of the Offer without the prior
written consent of the Company.  Notwithstanding the foregoing, Merger Sub may,
without the consent of the Company, (i) extend the Offer on one or more
occasions for an aggregate period of not more than 20 days, if at the scheduled
or extended expiration date of the Offer, the Minimum Condition shall not be
satisfied, (ii) extend the Offer from time to time until the earlier to occur of
(x) the satisfaction or waiver of all Offer Conditions or (y) August 31, 1998;
provided, however, that notwithstanding the foregoing, if all Offer Conditions
- --------  -------                                                             
other than the HSR Condition (as defined in Annex A hereto) have been satisfied
or waived, Merger Sub may, if such HSR Condition is reasonably capable of being
satisfied, extend the Offer without the consent of the Company until October 31,
1998 (either such date, as applicable, being the "EXTENSION DATE"), if at the
scheduled or extended expiration date of the Offer any of the Offer Conditions
(other than the Minimum Condition) which are reasonably capable of being
satisfied shall not be satisfied or waived, (iii) extend the Offer for any
period required by any rule, regulation, interpretation or position of the
United States Securities and Exchange Commission (the "SEC") or the staff
thereof applicable to the Offer and (iv) extend the Offer on one or more
occasions for an aggregate period of not more than 10 Business Days beyond the
latest expiration date that would otherwise be permitted under clause (i), (ii)
or (iii) of this sentence, if on such expiration date there shall not have been
tendered at least 90% of the outstanding Shares on a fully diluted basis;
provided, however, that if the Offer is extended pursuant to this clause (iv)
- --------  -------                                                            
hereof, the conditions to the Offer set forth in clauses (b), (f) or (h) of
Annex A hereto shall be deemed satisfied at all times thereafter.
Notwithstanding the foregoing, if requested by the Company, Merger Sub shall,
and Parent agrees to cause Merger Sub to, extend the Offer from time to time
until the earlier to occur of (x) the satisfaction or waiver of all Offer
Conditions or (y) the Extension Date if, and to the extent that, at the initial
expiration date of the Offer, or any extension thereof, all Offer Conditions
have not been satisfied or waived and all such conditions are reasonably capable
of being satisfied.  In addition, the Offer Price may be increased and the Offer
may be extended to the extent required by law in connection with such increase,
in each case without the consent of the Company.

          (b) As soon as practicable on the date the Offer is commenced, Parent
and Merger Sub shall file with the SEC a Tender Offer Statement on Schedule 14D-
1 with respect to the Offer (together with all amendments and supplements
thereto and including the

                                       2
<PAGE>
 
exhibits thereto, the "SCHEDULE 14D-1").  The Schedule 14D-1 will include, as
exhibits, the Offer to Purchase and a form of letter of transmittal and summary
advertisement (collectively, together with any amendments and supplements
thereto, the "OFFER DOCUMENTS").  The Offer Documents will comply in all
material respects with the provisions of applicable federal securities laws and,
on the date filed with the SEC and on the date first published, sent or given to
the Company's stockholders, shall not contain any untrue statement of a material
fact or omit to state any material fact required to be stated therein or
necessary in order to make the statements therein, in light of the circumstances
under which they were made, not misleading, except that no representation is
made by Parent or Merger Sub with respect to information supplied by the Company
or any of its stockholders in writing for inclusion or incorporation by
reference in the Offer Documents.  Each of Parent and Merger Sub further agrees
to take all steps necessary to cause the Offer Documents to be filed with the
SEC and to be disseminated to holders of Shares, in each case as and to the
extent required by applicable federal securities laws.  Each of Parent and
Merger Sub, on the one hand, and the Company, on the other hand, agrees promptly
to correct any information provided by it for use in the Offer Documents if and
to the extent that it shall have become false or misleading in any material
respect, and Merger Sub further agrees to take all steps necessary to cause the
Offer Documents as so corrected to be filed with the SEC and to be disseminated
to holders of Shares, in each case as and to the extent required by applicable
federal securities laws.  The Company and its counsel shall be given a
reasonable opportunity to review the initial Schedule 14D-1 before it is filed
with the SEC.  In addition, Parent and Merger Sub agree to provide the Company
and its counsel in writing with any comments or other communications that
Parent, Merger Sub or their counsel may receive from time to time from the SEC
or its staff with respect to the Offer Documents promptly after the receipt of
such comments or other communications.

          (c) Parent shall provide or cause to be provided to Merger Sub all of
the funds necessary to purchase any shares of Company Common Stock that Merger
Sub becomes obligated to purchase pursuant to the Offer.

          (d) Upon the consummation of the Offer, Parent agrees to make a loan
to the Company, on commercially reasonable terms, in an amount sufficient for
the Company to make payments to holders of Company Stock Options as set forth in
Section 2.4 hereof, or, if such amount cannot be borrowed by the Company for any
reason, to contribute such amount to the Company.

          1.2  COMPANY ACTIONS.  (a)    The Company hereby approves of and
               ---------------                                            
consents to the Offer and represents that the Board of Directors (as defined in
Section 8.13(b)), at a meeting duly called and held, has duly and unanimously
(i) approved this Agreement and the transactions contemplated hereby, including
the Offer and the Merger (as defined in the Recitals hereto) (collectively, the
"TRANSACTIONS") and (ii) determined, as of the date of such resolutions, that
the terms of the Offer and the Merger are fair to, and in the best interests of
the Company's stockholders, and resolved to recommend that the stockholders of
the Company accept the Offer, tender their Shares thereunder to Merger Sub and
approve and adopt this Agreement and the Merger (if required) and (iv) taken all
necessary steps to render Section 203 of the Delaware General Corporation Law
(the "DGCL") inapplicable to the Merger (it being understood that

                                       3
<PAGE>
 
(x) nothing in this Agreement shall prevent or prohibit the Company from
complying with Rule 14d-9 and Rule 14(e)(2) under the Exchange Act with respect
to an Acquisition Proposal and (y) such recommendation may be withdrawn,
modified or amended as provided in Section 5.4 hereof).  The Company has been
advised by each of its directors and executive officers listed on Schedule
                                                                  --------
1.2(a) annexed hereto that each such person currently intends to tender all
- ------                                                                     
Shares beneficially owned by such person pursuant to the Offer.

          (b) As promptly as practicable following the commencement of the Offer
and in all events not later than 10 business days following such commencement,
the Company shall file with the SEC a Solicitation/Recommendation Statement on
Schedule 14D-9 (together with all amendments and supplements thereto and
including the exhibits thereto, the "SCHEDULE 14D-9") which shall, subject to
the provisions of this Agreement, contain the recommendation referred to in
clause (ii) of Section 1.2(a) hereof.  The Schedule 14D-9 will comply in all
material respects with the provisions of applicable federal securities laws and,
on the date filed with the SEC and on the date first published, sent or given to
the Company's stockholders, shall not contain any untrue statement of a material
fact or omit to state any material fact required to be stated therein or
necessary in order to make the statements therein, in light of the circumstances
under which they were made, not misleading, except that no representation is
made by the Company with respect to information supplied by Parent or Merger Sub
in writing for inclusion in the Schedule 14D-9.  The Company further agrees to
take all steps necessary to amend or supplement the Schedule 14D-9 and to cause
the Schedule 14D-9 to be filed with the SEC and to be disseminated to holders of
Shares, in each case as and to the extent required by applicable federal
securities laws.  Each of the Company, on the one hand, and Parent and Merger
Sub, on the other hand, agrees promptly to correct any information provided by
it for use in the Schedule 14D-9 if and to the extent that it shall have become
false or misleading in any material respect, and the Company further agrees to
take all steps necessary to cause the Schedule 14D-9 as corrected to be filed
with the SEC and to be disseminated to holders of the Shares, in each case as
and to the extent required by applicable federal securities laws.  Parent and
its counsel shall be given a reasonable opportunity to review the initial
Schedule 14D-9 before it is filed with the SEC.  In addition, the Company agrees
to provide Parent, Merger Sub and their counsel in writing with any comments or
other communications that the Company or its counsel may receive from time to
time from the SEC or its staff with respect to the Schedule 14D-9 promptly after
the receipt of such comments or other communications.

          (c) In connection with the Offer and the Merger, the Company will
promptly furnish or cause to be furnished to Merger Sub mailing labels, security
position listings and any available listing or computer file containing the
names and addresses of the record holders of the Shares as of a recent date, and
shall furnish Merger Sub with such additional information (including updated
lists of holders of Shares and their addresses, mailing labels and lists of
security positions) and such other assistance as Merger Sub or its agents may
reasonably request in communicating the Offer to the record and beneficial
stockholders of the Company.  Except for such steps as are necessary to
disseminate the Offer Documents and as required by applicable law, each of
Parent and Merger Sub shall hold in confidence the information contained in any
of such labels and lists and the additional information referred to in the

                                       4
<PAGE>
 
preceding sentence, will use such information only in connection with the Offer
and the Merger, and, if this Agreement is terminated, will upon request of the
Company deliver, and use its reasonable best efforts to cause its agents and
representatives to deliver to the Company all copies of such information then in
its possession or the possession of its agents or representatives.

          1.3  DIRECTORS.        (a)  Promptly upon the purchase of and payment
               ---------                                                       
for Shares by Parent or any of its Subsidiaries (as defined in Section 8.13(j))
pursuant to the Offer, Parent shall be entitled to designate such number of
directors, rounded up to the next whole number, on the Board of Directors of the
Company as is equal to the product of the total number of directors on such
Board (giving effect to the directors designated by Parent pursuant to this
sentence) multiplied by the percentage that the aggregate number of Shares
beneficially owned by Merger Sub, Parent and any of their affiliates bears to
the total number of shares of Company Common Stock then outstanding.  The
Company shall, upon request of Merger Sub take any and all actions within the
Company's power which are necessary to cause Parent's designees to be appointed
to the Board of Directors (including by increasing the size of the Board of
Directors or using its best efforts to cause incumbent directors to resign).  At
such time, the Company shall use its best efforts to cause persons designated by
Parent to constitute the same percentage of each committee of the Board of
Directors, each board of directors of each Subsidiary and each committee of each
such board as such persons represent on the Board of Directors.  Notwithstanding
the foregoing, until the Effective Time (as defined in Section 1.6 hereof), the
Company shall retain as members of its Board of Directors at least two directors
who are directors of the Company on the date hereof (the "COMPANY DESIGNEES").
The Company's obligations under this Section 1.3(a) shall be subject to Section
14(f) of the Exchange Act and Rule 14f-1 promulgated thereunder.  The Company
shall promptly take all actions required pursuant to such Section 14(f) and Rule
14f-1 in order to fulfill its obligations under this Section 1.3(a), including
mailing to stockholders the information required to by such Section 14(f) and
Rule 14f-1 as is necessary to enable Parent's designees to be elected to the
Company's Board of Directors.  Parent or Merger Sub will supply the Company any
information with respect to either of them and their nominees, officers,
directors and affiliates required by such Section 14(f) and Rule 14f-1.

          (b) From and after the time, if any, that Parent's designees
constitute a majority of the Board of Directors and until the Effective Time any
amendment of this Agreement, any termination of this Agreement by the Company,
any extension of time for performance of any of the obligations of Parent of
Merger Sub hereunder, any waiver of any condition or any of the Company's rights
hereunder or other action by the Company hereunder may be effected only by the
action of a majority of the directors of the Company then in office who are
Company Designees, which action shall be deemed to constitute the action of the
full Board of Directors; provided, that if there shall be no such directors
(other than in breach hereof), such actions may be effected by unanimous vote of

                                   ARTICLE II

                            CONVERSION OF SECURITIES

          2.1  CONVERSION OF CAPITAL STOCK.  As of the Effective Time, by virtue
               ---------------------------                                      
of the Merger and without any action on the part of the holders of any shares of
Company Common Stock or common stock of Merger Sub (the "MERGER SUB COMMON
STOCK"):

          (a) Merger Sub Common Stock.  Each issued and outstanding share of
              -----------------------                                       
Merger Sub Common Stock shall be converted into and become one fully paid and
nonassessable share of common stock, par value $.01 per share, of the Surviving
Corporation.

          (b) Cancellation of Treasury Stock and Parent-Owned Stock.  Each share
              -----------------------------------------------------             
of Company Common Stock owned by the Company or any Subsidiary of the Company
and each share of Company Common Stock owned by Parent, Merger Sub or any other
wholly owned Subsidiary of Parent shall be cancelled and retired and shall cease
to exist and no consideration shall be delivered in exchange therefor.

          (c) Exchange of Shares.  Each issued and outstanding share of Company
              ------------------                                               
Common Stock (other than Shares to be cancelled in accordance with Section
2.1(b) hereof and any Dissenting Shares (as defined in Section 2.3 hereof, if
applicable)), shall be converted into the right to receive the Offer Price,
payable to the holder thereof, without interest (the "MERGER CONSIDERATION"),
upon surrender of the certificate formerly representing such share of Company
Common Stock in the manner provided in Section 2.2 hereof.  All such shares of
Company Common Stock, when so converted, shall no longer be outstanding and
shall automatically be cancelled and retired and shall cease to exist, and each
holder of a certificate representing any such shares shall cease to have any
rights with respect thereto, except the right to receive the Merger
Consideration therefor upon the surrender of such certificate in accordance with
Section 2.2 hereof, without interest, or to perfect any rights of appraisal as a
holder of Dissenting Shares that such holder may have pursuant to Section 262 of
the DGCL.

          2.2  EXCHANGE OF CERTIFICATES.
               ------------------------ 

          (a) Paying Agent.  Parent shall designate a bank or trust company
              ------------                                                 
reasonably acceptable to the Company to act as agent in order for the holders of
shares of Company Common Stock and the holders of Warrants in connection with
the Merger (the "PAYING AGENT") to receive the funds to which all such holders
shall become entitled pursuant to Section 2.1(c) or 2.5 hereof.  Before the
Effective Time, Parent shall deposit or cause to be deposited with the Paying
Agent such funds for timely payment hereunder.  Such funds shall be invested by
the Paying Agent as directed by Parent or the Surviving Corporation.

          (b) Exchange Procedures.  Parent shall instruct the Paying Agent to,
              -------------------                                             
as soon as reasonably practicable after the Effective Time but in no event more
than three business days thereafter, mail to each holder of record of a
certificate, which immediately before the Effective Time represented outstanding
shares of Company Common Stock (a "CERTIFICATE," or, collectively, the
"CERTIFICATES"), whose shares were converted pursuant to Section 2.1 hereto into
the right to receive the Merger Consideration (i) a letter of transmittal (which
shall specify that delivery shall be effected, and risk of loss and title to the
Certificates shall pass, only upon delivery of the Certificates to the Paying
Agent and shall be in such form and have such other provisions as Parent may
reasonably specify) and (ii) instructions for use in effecting the surrender of
the Certificates in exchange for payment of the Merger Consideration.  Upon
surrender of a Certificate for cancellation to the Paying Agent or to such other
agent or agents as may be appointed by Parent, together with such letter of
transmittal, duly executed, the holder of such Certificate shall be entitled to
receive in exchange therefor the Merger Consideration payable for each share of
Company Common Stock formerly represented by such Certificate and the
Certificate so surrendered shall forthwith be cancelled.  If payment of the
Merger Consideration is to be made to a person other than the person in whose
name the surrendered Certificate is registered, it shall be a condition of
payment that the Certificate so surrendered shall be properly endorsed or shall
be otherwise in proper form for transfer and that the person requesting such
payment shall have paid any transfer and other taxes required by reason of the
payment of the Merger Consideration to a person other than the registered holder
of the Certificate surrendered or shall have established to the satisfaction of
the Surviving Corporation that such tax either has been paid or is not
applicable.  Until surrendered as contemplated by this Section 2.2, each
Certificate shall be deemed at any time after the Effective Time to represent
only the right to receive the Merger Consideration in cash as contemplated by
this Section 2.2.  No interest will be paid or accrue on the cash payable upon
the surrender of any Certificate.

          (c) Transfer Books; No Further Ownership Rights in Company Common
              -------------------------------------------------------------
Stock.  At the Effective Time, the stock transfer books of the Company shall be
- -----                                                                          
closed and thereafter there shall be no further registration of transfers of
shares of Company Common Stock on the records of the Company.  From and after
the Effective Time, the holders of Certificates evidencing ownership of shares
of Company Common Stock outstanding immediately before the Effective Time shall
cease to have any rights with respect to such Shares, except as otherwise
provided for herein or by applicable law.  If, after the Effective Time,
Certificates are presented to the Surviving Corporation for any reason, they
shall be cancelled and exchanged as provided in this Article II.

          (d) Termination of Fund; No Liability.  At any time following one year
              ---------------------------------                                 
after the Effective Time, the Surviving Corporation shall be entitled to require
the Paying Agent to deliver to it any funds (including any interest received
with respect thereto) which had been made available to the Paying Agent and
which have not been disbursed to holders of Certificates, and thereafter such
holders shall be entitled to look to the Surviving Corporation (subject to
abandoned property, escheat or other similar laws) only as general creditors
thereof with respect to the Merger Consideration payable upon due surrender of
their Certificates, without any interest thereon.  Notwithstanding the
foregoing, neither the Surviving Corporation nor the Paying Agent shall be
liable to any holder of a Certificate for Merger Consideration delivered to a
public official pursuant to any applicable abandoned property, escheat or
similar law.

          2.3  DISSENTING SHARES.  Notwithstanding anything in this Agreement to
               -----------------                                                
the contrary, Shares outstanding immediately before the Effective Time and held
by a holder who has not voted in favor of the Merger or consented thereto in
writing and who has demanded appraisal for such Shares in accordance with the
DGCL ("DISSENTING SHARES") shall not be converted into a right to receive the
Merger Consideration, unless such holder fails to perfect or withdraws or
otherwise loses his or her right to appraisal.  A holder of Dissenting Shares
shall be entitled to receive payment of the appraised value of such Shares held
by him or her in accordance with the provisions of Section 262 of the DGCL,
unless, after the Effective Time, such holder fails to perfect or withdraws or
loses his or her right to appraisal, in which case such Shares shall be treated
as if they had been converted as of the Effective Time into a right to receive
the Merger Consideration, without interest thereon.  The Company shall give
Parent (i) prompt notice of any demands for appraisal of Shares received by the
Company and (ii) the opportunity to participate in and direct all negotiations
and proceedings with respect to any such demands.  The Company shall not,
without the prior written consent of Parent, make any payment with respect to,
or settle, offer to settle or otherwise negotiate, any such demands.

          2.4  COMPANY OPTION PLANS.
               -------------------- 

          (a) All outstanding options to purchase Company Common Stock held by
all current and former employees and directors of the Company ("COMPANY STOCK
OPTIONS") granted to such employees and directors under any Company Benefit Plan
(as defined in Section 3.1(b)(i)), whether or not then exercisable, shall be
made fully vested and exercisable and canceled by the Company immediately before
the earlier of (x) the consummation of the Offer or (y) the Effective Time, and
thereafter, the holders' sole right shall be to, and the holders thereof shall,
receive from the Company, for each Share subject to such Company Stock Option,
an amount in cash equal to the difference between the Offer Price and the
exercise price per share of such Company Stock Option, which amount shall be
paid by the Company at the time such Company Stock Option is canceled.  The
Company will use its best efforts to obtain any necessary consents and make any
amendments to the terms of the Company Benefit Plans to the extent such consents
or amendments are necessary to give effect to the foregoing.  All applicable
withholding taxes attributable to the payments made hereunder shall be deducted
from the amounts payable under this Section 2.4.

                                       9
<PAGE>
 
          (b) Prior to the Effective Time, the Company's employee stock benefit
plans shall be terminated and the provisions in any other Company Benefit Plan
providing for the issuance or grant of any other interest in respect of the
capital stock of the Company or any Subsidiary shall be deleted.  The Company
shall take all actions necessary to ensure that following the Effective Time no
holder of a Company Stock Option or any participant in any Company Benefit Plan
shall have the right thereunder to acquire any capital stock of the Company,
Parent, the Surviving Corporation or any of their respective Subsidiaries,
except as provided in this Section 2.4.

          2.5  WARRANTS.
               -------- 

          (a)  In accordance with the terms of the ESJ Exchange Agreement dated
as of June 5, 1992 among the ESJ Entities, TPC Holding Corp. and the Company and
the warrant certificates issued thereunder (the "Warrant Certificates"), all
outstanding warrants of the Company issued pursuant thereto (the "ESJ WARRANTS")
(other than ESJ Warrants owned by Parent, Merger Sub or any other direct or
indirect subsidiary of Parent, which ESJ Warrants shall be canceled and
extinguished at the Effective Time, with no payment being made with respect to
such ESJ Warrants) shall, following the Effective Time, be exercisable only for
an amount of cash equal to the Offer Price and the holders of such ESJ Warrants
shall be entitled to receive, upon surrender to the Paying Agent of the warrant
certificates for cancellation, cash in an amount equal to the Warrant
Consideration.   The Company shall take all actions necessary to ensure that
following the Effective Time (i) the ESJ Warrants shall represent only the right
to receive the Warrant Consideration in lieu of Shares issuable upon exercise
thereof, (ii)  all warrant agreements shall be terminated and cancelled and
(iii) no party to such warrant agreements shall have the right to acquire any
capital stock of the Company, Parent, the Surviving Corporation or any of their
respective subsidiaries.

          (b) In accordance with the terms of the Lenders' Equity Agreement
dated as of June 5, 1992 between the Company and certain banks and other
financial institutions (the "Banks"), the Banks hold certain rights (the "BANK
WARRANTS" and, collectively with the ESJ Warrants, the "WARRANTS") entitling
them to receive an aggregate of 4,858 Shares (upon payment of $.01 per Share)
upon the exercise of the ESJ Warrants by the holders thereof.  The Company
agrees to use its best efforts to (i) obtain, prior to the Effective Time,
consents or waivers from each Bank whereby such Bank agrees to receive the
Warrant Consideration in lieu of Shares issuable upon the exercise of the Bank
Warrants and (ii) ensure that following the Effective Times (x) the Bank
Warrants shall represent only the right to receive cash in an amount equal to
the per share Offer Price less $.01 per share, (y) the Lenders' Equity Agreement
shall be terminated and cancelled and (z) no party to such Lenders' Equity
Agreement shall have the right to acquire any capital stock of the Company,
Parent, the Surviving Corporation or any of their respective Subsidiaries..

          (c) As used herein "WARRANT CONSIDERATION" shall mean an amount per
Warrant equal to the product of (i) the number of Shares issuable upon exercise
of such Warrant and (ii) the difference between the Offer Price and the per
Share exercise price per Warrant, without interest, which amount shall be paid
from and after the Effective Time.

          2.6  LOST CERTIFICATES.  If any Certificate or Warrant Certificate
               -----------------                                            
shall have been lost, stolen or destroyed, upon the making of an affidavit of
that fact by the Person claiming such Certificate or Warrant 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 or Warrant Certificate, the Paying Agent
will deliver in exchange for such lost, stolen or destroyed Certificate or
Warrant Certificate the applicable Merger Consideration or Warrant
Consideration, as the case may be, with respect to the shares of Company Common
Stock or Warrants formerly represented thereby.

          2.7  WITHHOLDING RIGHTS.  Each of the Surviving Corporation and Parent
               ------------------                                               
shall be entitled to deduct and withhold from the consideration otherwise
payable pursuant to this Agreement to any holder of shares of Company Common
Stock or Warrants such amounts as it is required to deduct and withhold with
respect to the making of such payment under the Internal Revenue Code of 1986,
as amended, and the regulations promulgated thereunder and the rules and
regulations promulgated thereunder, or any provision of state, local or foreign
tax law. To the extent that amounts are so withheld by the Surviving Corporation
or Parent, as the case may be, such withheld amounts shall be treated for all
purposes of this Agreement as having been paid to the holder of the shares of
Company Common Stock or Warrants in respect of which such deduction and
withholding was made by the Surviving Corporation or Parent, as the case may be.

          2.8  FURTHER ASSURANCES.  At and after the Effective Time, the
               ------------------                                       
officers and directors of the Surviving Corporation will be authorized to
execute and deliver, in the name and on behalf of the Company or Merger Sub, any
deeds, bills of sale, assignments or assurances and to take and do, in the name
and on behalf of the Company or Merger Sub, any other actions and things to
vest, perfect or confirm of record or otherwise in the Surviving Corporation any
and all right, title and interest in, to and under any of the rights, properties
or assets acquired or to be acquired by the Surviving Corporation as a result
of, or in connection with, the Merger.

                         REPRESENTATIONS AND WARRANTIES

          3.1  REPRESENTATIONS AND WARRANTIES OF THE COMPANY.  Except as set
               ---------------------------------------------                
forth in the Company SEC Reports (as defined in Section 3.1(d)) filed prior to
the date hereof or in the Company Disclosure Schedule delivered by the Company
to Parent before the execution of this Agreement (the "COMPANY DISCLOSURE
SCHEDULE"), the Company represents and warrants to Parent and Merger Sub as
follows:

          (a) Organization, Standing and Power.  Each of the Company and its
              --------------------------------

<PAGE>
 
business as now conducted and (3) is duly qualified as a foreign corporation,
limited liability company or limited partnership, as the case may be, under the
laws of each jurisdiction in which qualification is required either to own,
lease, license or use its properties now owned, leased, licensed and used or to

obtain such qualification, individually or in the aggregate, would not
constitute a Company Material Adverse Effect.  "COMPANY MATERIAL ADVERSE EFFECT"

that is reasonably likely to be materially adverse to the business, financial
condition or results of operations of the Company and its Subsidiaries taken as
a whole or on transactions contemplated hereby, other than any change,

general, (ii) relating to the industries in which the Company operates and not
specifically relating to the Company or (iii) resulting from the execution of
this Agreement, the announcement of this Agreement and the Transactions
contemplated hereby or any change in the value of the Company relating to such

bylaws of the Company, which were previously furnished to Parent, are complete
copies of such documents as in effect on the date of this Agreement.

          (b)  Capital Structure.
               ----------------- 

               (i) The authorized capital stock of the Company consists solely
     of 30,000,000 shares of Company Common Stock and 10,000,000 shares of
     preferred stock, par value $.01 per share (the "PREFERRED STOCK").  As of
     June 9, 1998, 14,766,575 shares of Company Common Stock were issued and
     outstanding, no shares of Preferred Stock were issued and outstanding, no
     shares of capital stock were held in the treasury of the Company and
     2,510,021 shares of Company Common Stock were reserved for issuance

     such date, there have been no issuances of shares of the capital stock of
     the Company or any other securities of the Company other than issuances of
     shares pursuant to options or rights outstanding as of such date under the
     Company Benefit Plans.  All issued and outstanding shares of the capital
     stock of the Company are and all shares reserved for issuance will be, when
     issued in accordance with the terms specified in the commitments or
     agreements pursuant to which they are issuable, duly authorized, validly
     issued, fully paid and nonassessable, and no class of capital stock is
     entitled to preemptive rights.  As of June 9, 1998 except for (i) options
     representing in the aggregate the right to purchase 1,375,414 shares of
     Company Common Stock under the Company Benefit Plans and (ii) 809,014
     Warrants validly issued and currently exercisable for 809,014 shares of
     Company Common Stock in the aggregate, there were no, and at the Effective
     Time (except pursuant to this Agreement) there will not be any, outstanding
     securities, options, subscriptions, warrants, calls, rights (including
     "phantom" stock rights), preemptive rights or other contracts, commitments,
     understandings or arrangements, including any right of conversion or
     exchange under any outstanding security, instrument or agreement (together,
     "OPTIONS") obligating the Company or any of its Subsidiaries to issue,
     deliver or sell or cause to be issued, delivered or sold any shares of
     capital stock of the Company or to issue, grant, extend or enter into any
     Option with respect thereto or to repurchase, redeem or otherwise acquire
     any share of capital stock of the Company.  The

                                       12

     Company is not a party to any voting agreement with respect to the voting
     of any of its securities.  "COMPANY BENEFIT PLANS" means each employee
     benefit plan, program, arrangement and contract (including but not limited
     to any "employee benefit plan," as defined in Section 3(3) of the Employee
     Retirement Income Security Act of 1974, as amended ("ERISA") , whether or
     not subject to ERISA and any bonus, deferred compensation, incentive, stock

     this Agreement and, in the case of a Company Benefit Plan which is subject
     to Part 3 of Title I of ERISA, Section 412 of the Code or Title IV of
     ERISA, at any time during the five-year period preceding the date of this
     Agreement, to which the Company is a party, which is maintained or
     contributed to by the Company or a Subsidiary, or with respect to which the

          5.3  BEST EFFORTS.
               ------------ 

          (a) Subject to the terms and conditions of this Agreement, each party
will use its reasonable best efforts to take, or cause to be taken, all actions
and to do, or cause to be done, all things necessary, proper or advisable under
applicable laws and regulations to consummate the Offer, the Merger and the
other Transactions contemplated by this Agreement as soon as practicable after
the date hereof.  In furtherance and not in limitation of the foregoing, each
party hereto agrees to make, to the extent it has not already done so, an
appropriate filing of a Notification and Report Form pursuant to the HSR Act
with respect to the Transactions contemplated hereby as promptly as practicable
and to supply as promptly as practicable any additional information and
documentary material that may be requested pursuant to the HSR Act and to take
all other actions necessary to cause the expiration or termination of the
applicable waiting periods under the HSR Act as soon as practicable.

          (b) Each of the Company and Parent shall, in connection with the
efforts referenced in Section 5.3(a) to obtain all requisite approvals and
authorizations for the Transactions contemplated by this Merger Agreement under
the HSR Act or any other Regulatory Law (as defined below), use its reasonable
best efforts to (i) cooperate in all respects with each other in connection with
any filing or submission and in connection with any investigation or other
inquiry, including any proceeding initiated by a private party, (ii) promptly
inform the other party of any communication received by such party from, or
given by such party to, the Antitrust Division of the Department of Justice (the

case regarding any of the Transactions contemplated hereby, and (iii) permit the
other party to review any communication given by it to, and consult with each
other in advance of any meeting or conference with, the DOJ or any such other
Governmental Entity or, in connection with any proceeding by a private party,
with any other Person, and to the extent permitted by the DOJ or such other
applicable Governmental Entity or other Person, give the other party the
opportunity to attend and participate in such meetings and conferences.  For
purposes of this Agreement, "REGULATORY LAW" means the Sherman Act, as amended,
the Clayton Act, as amended, the HSR Act, the Federal Trade Commission Act, as
amended, and all other federal, state and foreign, if any, statutes, rules,
regulations, orders, decrees, administrative and judicial doctrines and other
laws that are designed or intended to prohibit, restrict or regulate actions
having the purpose or effect of monopolization or restraint of trade or
lessening of competition through merger or acquisition.

<PAGE>
 
          (c) In furtherance and not in limitation of the covenants of the
parties contained in Sections 5.3(a) and 5.3(b), if any administrative or
judicial action or proceeding, including any proceeding by a private party, is
instituted (or threatened to be instituted) challenging any transaction
contemplated by this Agreement as violative of any Regulatory Law, each of the
Company and Parent shall cooperate in all respects with each other and use its
respective reasonable best efforts to contest and resist any such action or
proceeding and to have vacated, lifted, reversed or overturned any decree,
judgment, injunction or other order, whether temporary, preliminary or
permanent, that is in effect and that prohibits, prevents or restricts
consummation of the Transactions contemplated by this Agreement.
Notwithstanding the foregoing or any other provision of this Agreement, nothing
in this Section 5.3 shall limit a party's right to terminate this Agreement
pursuant to Section 7.1(b)(ii) so long as such party has complied in all
material respects with its obligations under this Section 5.3.

          5.4  ACQUISITION PROPOSALS.  The Company agrees that neither it nor
               ---------------------                                         
any of its Subsidiaries shall, and that it shall direct and use its reasonable
best efforts to cause its and its Subsidiaries' directors, officers, employees,
agents and representatives (including any investment banker, attorney or
accountant retained by it or any of its Subsidiaries) not to, directly or
indirectly, initiate, solicit, encourage or knowingly facilitate (including by
way of furnishing information) any inquiries or the making of any proposal or
offer with respect to a merger, reorganization, share exchange, consolidation,
business combination, recapitalization, liquidation, dissolution or similar
transaction involving, or any purchase or sale of all or any significant portion
of the assets of, it or any of its Subsidiaries or any purchase or sale of more
than 25% of the equity securities of the Company or any equity securities of any
Significant Subsidiary (as that term is defined in Rule 405 under the Securities
Act) (any such proposal or offer whether or not in writing or in sufficient
detail to be accepted and whether or not conditional (other than a proposal or
offer made by Parent or an affiliate thereof) being hereinafter referred to as
an "ACQUISITION PROPOSAL").  The Company further agrees that neither it nor any
of its Subsidiaries shall, and that it shall direct and use its best efforts to
cause its and its Subsidiaries' directors, officers, employees, agents and
representatives (including any investment banker, attorney or accountant
retained by it or any of its Subsidiaries) not to, directly or indirectly, have
any discussion with or provide any confidential information or data to any
Person relating to an Acquisition Proposal, or engage in any negotiations
concerning an Acquisition Proposal, or knowingly facilitate any effort or
attempt to make or implement an Acquisition Proposal or accept an Acquisition
Proposal.  Notwithstanding the foregoing, the Company or its Board of Directors
shall be permitted, at any time prior to the acceptance for payment of the
Shares pursuant to the Offer, to (A) engage in discussions or negotiations with,
or provide information to, any Person in response to an unsolicited Acquisition
Proposal by such Person if (x) the Board of Directors of the Company concludes
in good faith that such Acquisition Proposal constitutes or could reasonably be
expected to lead to a Superior Proposal and (y), before providing any
information to such Person, the Board of Directors receives from such Person an
executed confidentiality agreement containing confidentiality provisions
substantially similar to those contained in the Confidentiality Agreement; and
(B) if the Board of Directors concludes in good faith that such Acquisition
Proposal constitutes a Superior Proposal (i) recommend approval of such Superior
Proposal, (ii) in response to such Superior Proposal, withdraw or modify in an
adverse manner the Company Board Approval, or (iii) enter into an agreement in
principle or

                                       26
<PAGE>
 
a definitive agreement with respect to such Superior Proposal, provided,
                                                               -------- 
however, that, in the case of either (A) or (B) the Board of Directors of the
- -------                                                                      
Company determines in good faith after consultation with outside counsel that it
should take such action consistent with its fiduciary duties under applicable
law.  In the event the Company shall determine to provide any information as
described above, or shall receive any Acquisition Proposal, it shall promptly
inform Parent as to the fact that information is to be provided or that an
Acquisition Proposal has been received and shall furnish to Parent a description
of the material terms thereof.  As used in this Agreement, "SUPERIOR PROPOSAL"
means a bona fide Acquisition Proposal which the Company Board of Directors
concludes in good faith (after consultation with its financial advisors and
legal counsel), taking into account all legal, financial, regulatory and other
aspects of the proposal and the Person making the proposal, provides for a
transaction that, taking into account its likelihood of completion, is more
favorable to the Company's stockholders (in their capacities as stockholders),
than the Transactions contemplated by this Agreement.

the terms and provisions of the severance plan described on Schedule 5.5(b).

employee benefit plans, policies or arrangements (other than stock-based plans
or stock-based provisions in plans) for the benefit of employees of the Company
and its Subsidiaries (other than those employees who are employed pursuant to a
collective bargaining agreement or who are members of a collective bargaining
unit or labor union) which are substantially comparable in the aggregate to the
employee benefit plans, policies or arrangements of the Company in effect on the
date hereof (other than stock-based plans or stock-based provisions in the
plans) set forth on Schedule 5.5(c).

          (d) Benefit Plan Eligibility.  Parent agrees that it shall, or it
              ------------------------                                     
shall cause the Company and the Surviving Corporation to, give employees of the
Company and/or any of its Subsidiaries full credit for service for purposes of
eligibility, vesting and satisfaction of waiting periods under any employee
benefit plans, policies or arrangements maintained by the Company, Parent or the
Surviving Corporation in which such employees are entitled to participate.
Employees of the Company and/or any of its Subsidiaries shall not be subject to
any pre-existing condition exclusions or limitations under Parent's or the
Surviving Corporation's benefit plans (except to the extent that such exclusions
presently apply to an employee under the Company's and/or any of such
Subsidiaries' benefit plans).

          5.6  FEES AND EXPENSES.  Whether or not the Offer is consummated, all

to be paid, any and all property or transfer taxes imposed on the Company or its

5.10 shall be repaid by the Company or the Surviving Corporation, as the case

used in this Agreement, "EXPENSES" includes all out-of-pocket expenses
(including all fees and expenses of counsel, accountants, investment bankers,
experts and consultants to a party hereto and its affiliates) incurred by a
party or on its behalf in connection with or related to the authorization,
preparation, negotiation, execution and performance of this Agreement and the
Transactions contemplated hereby, including the preparation, printing, filing

          5.7  DIRECTORS' AND OFFICERS' INDEMNIFICATION AND INSURANCE.
               ------------------------------------------------------ 

          (a) Until the expiration of all applicable statutes of limitations,
from and after the consummation of the Offer, the Company shall and Parent shall
cause the Company (or any successor to the Company) to, and from and after the
Effective Time, Parent and Surviving Corporation shall, indemnify, defend and
hold harmless the present and former officers and directors of the Company and
its Subsidiaries (each an "INDEMNIFIED PARTY") against all losses, claims,
damages, liabilities, fees, penalties and expenses (including reasonable fees
and disbursements of counsel and judgments, fines, losses, claims, liabilities
and amounts paid in settlement arising out of actions or omissions occurring at
or before the consummation of the Offer) (including losses incurred in
connection with such person's serving as a trustee or other fiduciary in any
entity if such service was at the request or for the benefit of the Company or
any of its subsidiaries) to the full extent permitted by the DGCL, such right to
include the right to advancement of expenses incurred in the defense of any
action or suit promptly after statements therefor are received to the fullest
extent permitted by law; provided that the Indemnified Party to whom expenses
are advanced provides an undertaking to repay such advance if it is ultimately
determined that such party is not entitled to indemnification.

                                       28
<PAGE>
 
Notwithstanding the foregoing, an Indemnifying Party shall not be liable for any
settlement of any claim effected without such Indemnifying Party's written
consent, which consent shall not be unreasonably withheld.  Parent will
cooperate in the defense of any such matter.

          (b) Parent or the Surviving Corporation shall maintain the Company's
existing directors' and officers' liability insurance on behalf of the
Indemnified Parties, including any such insurance maintained on behalf of any
such Indemnified Party serving as a director or officer of any Subsidiary of the
Company, including coverage with respect to claims arising from facts or events
which occurred at or before the consummation of the Offer ("D&O INSURANCE") for
a period of not less than six years after the consummation of the Offer;
provided, however, that Parent may substitute therefor policies of substantially
similar coverage with a face amount not less that the existing D&O Insurance and
containing terms no less favorable to such Indemnified Parties; provided,
further, if the existing D&O Insurance expires, is terminated or cancelled
during such period, Parent or the Surviving Corporation will obtain
substantially similar D&O Insurance.

          (c) The certificate of incorporation and the bylaws of the Company
and, after the Effective Time, the Surviving Corporation shall contain the
provisions with respect to advancement of expenses, indemnification and
exculpation from liability set forth in the certificate of incorporation and
bylaws of the Company on the date of this Agreement, which provisions shall not
for a period of ten years following the Effective Time be amended, repealed or
otherwise modified in any manner that would adversely affect the rights
thereunder of individuals who on or before the consummation of the Offer were
entitled to advances, indemnification or exculpation thereunder, including any
individuals serving as directors or officers of any Subsidiary of the Company at
the Company's request, it being acknowledged by the parties hereto that each
director or officer of the Company that is currently serving as a director or
officer of a Subsidiary of the Company is doing so at the request of the
Company.

          (d) In the event Parent or the Surviving Corporation or any of their
respective successors or assigns (i) consolidates with or merges into any other
Person and shall not be the continuing or surviving corporation or entity in
such consolidation or merger or (ii) transfers all of substantially all its
properties and assets to any Person, then, and in each case, proper provision
shall be made so that the successors and assigns of Parent or the Surviving
Corporation, as the case may be, honor the indemnification obligations set forth
in this Section 5.7.

          (e) The obligations of the Company, Parent and the Surviving
Corporation under this Section 5.7 shall not be terminated, modified or assigned
in such a manner as to materially adversely affect any Indemnified Party without
the consent of such Indemnified Party (it being expressly agreed that the
Indemnified Parties shall be third-party beneficiaries of this Section 5.7).

          5.8  PUBLIC ANNOUNCEMENTS.  The Company and Parent shall use all
               --------------------                                       
reasonable efforts to develop a joint communications plan, and each party shall
use all reasonable efforts (i) to ensure that all press releases and other

each other before issuing any press release or otherwise making any public

hereby.

to the 10 1/2% Senior Notes due 2003 (the "SENIOR NOTES"), within five days
following the acquisition by Parent or Merger Sub of beneficial ownership,
directly or indirectly, of more than 50% of the Common Stock, the Company shall,
in accordance with the Indenture, notify the Trustee and, the Company or the
Surviving Corporation, as the case may be, within 20 business days prior to the
Final Change of Control Put Date (as defined in the Indenture), give written
notice to each holder of the Senior Notes, stating, among other things, (i) that
a Change of Control (as defined in the Indenture) has occurred, (ii) that each
holder of the Senior Notes has the right to require the Company to repurchase
such holder's Senior Notes at a purchase price in cash in an amount equal to
101% of the principal amount of such Senior Notes, plus accrued and unpaid
interest thereon, if any, to the purchase date thereof and (iii) the date on
which such Senior Notes shall be purchased which shall be a business day no
later than 40 business days after the occurrence of or Change of Control.
Parent shall lend or contribute to the Company an amount in cash necessary to
repurchase all such Senior Notes.

          5.10 CREDIT AGREEMENT.  The Company shall use its best efforts to

obtain all necessary waivers and consents prior to the consummation of the Offer
so that the transactions contemplated hereby will not result in or constitute a
default under that certain Credit Agreement dated as of August 4, 1993, as
amended, by and among the Company, Lenders, Bank of America NT & SA, as Co-Agent
for Lenders and The Bank of Nova Scotia, as the Agent for Lenders (the "CREDIT
AGREEMENT").  In the event that (i) such waiver and consent is not obtained,
(ii) the transactions contemplated hereby result in a default and the Lenders
under the Credit Agreement accelerate the payment of outstanding indebtedness
thereunder, and (iii) the Company, after using its best efforts, is unable to
refinance or repay such indebtedness, then, following the consummation of the
Offer, Parent agrees to make a loan to the Company in an amount sufficient for
the Company to repay the outstanding Indebtedness and any other obligations
under the Credit Agreement, or, if such amount cannot be borrowed by the Company
for any reason, to contribute such amount to the Company.

          (a) This Agreement and the Confidentiality Agreement constitute the

is intended to or shall confer upon any other Person any right, benefit or
remedy of any nature whatsoever under or by reason of this Agreement, other than

covered thereby and may be enforced by such Persons).

of time which need only be true and accurate as of such date or with respect to

by the Merger Agreement to be performed or complied with by it except, in the
case



                                      A-1
