To the Holders of Common Stock of

INNOVATIVE VALVE TECHNOLOGIES, INC.:

                                  INTRODUCTION

     Forrest Acquisition Sub, Inc. a Delaware corporation ("Purchaser") and a
wholly-owned subsidiary of FLOWSERVE CORPORATION, a New York corporation
("Parent"), hereby offers to purchase all outstanding shares of common stock
("Common Stock"), $.001 par value per share, of INNOVATIVE VALVE TECHNOLOGIES,
INC. a Delaware corporation (the "Company"), including the associated rights to
purchase Series A Junior Participating Preferred Stock (the "Rights," and
together with the Common Stock, the "Shares"), at a purchase price of $1.62 per
Share (the "Offer Price"), net to the seller in cash, without interest thereon,
upon the terms and subject to the conditions set forth in this Offer to Purchase
and in the related Letter of Transmittal (which, together with any amendments or
supplements hereto or thereto, collectively constitute the "Offer"). The Rights
were issued pursuant to the Rights Agreement, dated as of September 18, 1997, as
amended by Amendment No. 1 thereto dated as of November 18, 1999 (as so amended,
the "Rights Agreement") between the Company and ChaseMellon Shareholder
Services, L.L.C., as Rights Agent, and are currently evidenced by and traded
with certificates evidencing the Common Stock.

     Tendering stockholders who have Shares registered in their own name and who
tender directly to the Depositary (as defined below) will not be obligated to
pay brokerage fees or commissions or, except as set forth in Instruction 6 of
the Letter of Transmittal, transfer taxes on the purchase of Shares pursuant to
the Offer. Stockholders who hold their Shares in "street name" or otherwise
through a broker, bank or other nominee should consult with such institution as
to whether there are any fees applicable to a tender of Shares. Purchaser will
pay all charges and expenses of Equiserve, as the depositary (the "Depositary"),
and D.F. King & Co., Inc., as the information agent (the "Information Agent"),
in connection with the Offer.

     The Offer is being made pursuant to the Agreement and Plan of Merger, dated
as of November 18, 1999 (the "Merger Agreement"), among Parent, Purchaser and
the Company. The Merger Agreement provides, among other things, for the
commencement of the Offer by Purchaser and further provides that, after the
purchase of Shares pursuant to the Offer and subject to the satisfaction or
waiver of certain conditions set forth therein, Purchaser will be merged (the
"Merger") with and into the Company with the Company surviving the Merger as a
direct wholly-owned subsidiary of Parent. Pursuant to the Merger, each
outstanding Share (excluding Shares owned, directly or indirectly, by the
Company, Parent, Purchaser or any other subsidiary of Parent and Shares owned by
holders who shall have properly exercised their appraisal rights under the
Delaware General Corporation Law (the "DGCL") will be converted into the right
to receive the Offer Price, in cash (the "Merger Consideration"), without
interest.

     THE BOARD OF DIRECTORS OF THE COMPANY (THE "BOARD") HAS UNANIMOUSLY
DETERMINED THAT THE OFFER AND THE MERGER ARE ADVISABLE AND FAIR TO, AND IN THE
BEST INTERESTS OF, THE HOLDERS OF SHARES, HAS APPROVED THE MERGER AGREEMENT AND
THE TRANSACTIONS CONTEMPLATED THEREBY, INCLUDING THE OFFER AND THE MERGER, AND
RECOMMENDS THAT STOCKHOLDERS ACCEPT THE OFFER AND TENDER THEIR SHARES TO
PURCHASER HEREUNDER.

     SIMMONS & COMPANY INTERNATIONAL, THE COMPANY'S FINANCIAL ADVISOR
("SIMMONS"), HAS DELIVERED TO THE COMPANY'S BOARD SUCH FIRM'S OPINION, DATED
NOVEMBER 17, 1999 (THE "OPINION"), TO THE EFFECT THAT, AS OF SUCH DATE AND BASED
ON AND SUBJECT TO CERTAIN MATTERS STATED IN SUCH OPINION, THE $1.62 PER SHARE
CASH CONSIDERATION TO BE RECEIVED IN THE OFFER AND THE MERGER BY STOCKHOLDERS
(OTHER THAN PARENT AND ITS AFFILIATES) IS FAIR, FROM A FINANCIAL POINT OF VIEW,
TO SUCH STOCKHOLDERS. A COPY OF THE OPINION IS CONTAINED IN THE COMPANY'S
SOLICITATION/RECOMMENDATION STATEMENT ON SCHEDULE 14D-9 (THE "SCHEDULE 14D-9")
FILED WITH THE SECURITIES AND EXCHANGE COMMISSION (THE "COMMISSION") IN
CONNECTION WITH THE OFFER, A COPY OF WHICH IS BEING FURNISHED TO STOCKHOLDERS
CONCURRENTLY WITH THIS OFFER TO PURCHASE. STOCKHOLDERS ARE URGED TO READ THE
OPINION IN ITS ENTIRETY FOR A DESCRIPTION OF THE ASSUMPTIONS MADE, MATTERS
CONSIDERED AND LIMITATIONS OF THE REVIEW UNDERTAKEN BY SIMMONS.

     THE OFFER IS CONDITIONED UPON, AMONG OTHER THINGS, THERE BEING VALIDLY
TENDERED AND NOT WITHDRAWN PRIOR TO THE EXPIRATION DATE AT LEAST THAT NUMBER OF
SHARES THAT WOULD REPRESENT A MAJORITY OF THE SHARES
<PAGE>   4

OUTSTANDING ON A FULLY DILUTED BASIS ON THE DATE OF PURCHASE (THE "MINIMUM
CONDITION"). FOR PURPOSES OF THE MINIMUM CONDITION, "FULLY DILUTED BASIS"
EXCLUDES (1) SHARES ISSUABLE UPON EXERCISE OF CERTAIN STOCK OPTIONS ("OPTIONS")
FOR WHICH TERMINATION AGREEMENTS ARE ENTERED INTO PRIOR TO THE EXPIRATION TIME
PURSUANT TO THE TERMS OF THE MERGER AGREEMENT AND (2) SHARES ISSUABLE PURSUANT
TO CERTAIN WARRANTS, CONVERTIBLE NOTES AND ACQUISITION AGREEMENTS (OTHER THAN
THE COLLIER MERGER AGREEMENT (AS DEFINED IN THE MERGER AGREEMENT)) THAT WILL BE
TERMINATED, CANCELLED OR OTHERWISE DISCHARGED PURSUANT TO THE MERGER AGREEMENT.
SEE SECTION 12 BELOW. THE OFFER ALSO IS SUBJECT TO CERTAIN OTHER CONDITIONS. SEE
SECTIONS 1 AND 14 BELOW.

     The Company has informed Purchaser that, as of November 17, 1999, 9,664,562
shares were issued and outstanding, 1,650,000 shares were reserved for issuance
upon the exercise of outstanding Options granted under the Company's Stock Plans
(as defined herein), 482,262 shares were reserved for issuance upon the exercise
of outstanding Warrants (as defined herein), 600,769 shares were reserved for
issuance upon conversion of Convertible Notes (as defined herein), 555,555
shares were reserved for issuance in connection with the Company's obligations
under the Collier Merger Agreement, and an indeterminate number of Shares were
reserved for issuance in connection with the Company's obligations under the
Colonial Merger Agreement and the Plant Maintenance Merger Agreement (each, as
defined in the Merger Agreement). Based on the foregoing and assuming that
termination agreements are entered into with respect to all outstanding Options,
Purchaser believes that as of such date, the Minimum Condition will be satisfied
if Purchaser acquires 4,832,282 shares. Parent and Purchaser do not presently
own any Shares.

     Concurrently with the execution of the Merger Agreement, Purchaser also
entered into a Stockholder Agreement dated November 18, 1999 (the
"Stockholder/Option Agreement") with Roger L. Miller, William E. Haynes, Charles
F. Schugart and Douglas R. Harrington, Jr. (collectively, the "Granting
Stockholders"), pursuant to which the Granting Stockholders, among other things,
agreed to tender (and not withdraw) their Shares in the Offer, granted an
irrevocable proxy to Purchaser's designees with respect to their Shares and
granted to Purchaser an option to purchase the Shares held by them at the Offer
Price under specified circumstances. In addition, Purchaser entered into a
Stockholder Agreement dated November 18, 1999 (each, a "Chapter 11 Stockholder
Agreement," and together with the Stockholder/Option Agreement, the "Stockholder
Agreements") with each of Philip Industrial Services Group, Inc. and Philip
Environmental Services, Inc. (jointly, the "Chapter 11 Stockholders," and
together with the Granting Stockholders, the "Selling Stockholders"). The
Chapter 11 Stockholders are affiliates of Philip Services Corp. and have filed
voluntary petitions for reorganization under Chapter 11 of the U.S. Bankruptcy
Code with the Bankruptcy Court for the District of Delaware (the "Delaware
Bankruptcy Court"). Each Chapter 11 Stockholder Agreement is similar to the
Stockholder/Option Agreement but (1) does not contain an option to purchase
provision; and (2) is effective upon the earlier to occur of (x) Delaware
Bankruptcy Court approval of such Chapter 11 Stockholder Agreement and the
transactions contemplated thereby and (y) the confirmation by the Delaware
Bankruptcy Court of a plan of reorganization for the Chapter 11 Stockholder
party to such Chapter 11 Stockholder Agreement. The Selling Stockholders
collectively own 3,125,400 shares. Assuming that termination agreements are
entered into with respect to all outstanding Options and that the Selling
Stockholders tender in the Offer, as they have agreed to do, Purchaser believes
that the Minimum Condition will be satisfied if 1,706,882 Shares (approximately
18% of the outstanding Shares) are tendered and not withdrawn by other
stockholders.

     The Company has represented in the Merger Agreement that is has taken all
action necessary so that (x) none of Parent, Purchaser or any of their
Affiliates or Associates (as such terms are defined in the Rights Agreement)
shall be or become an "Acquiring Person", and no Stock Acquisition Date,
Distribution Date, Flip-in Event or Flip-Over Event (as such terms are defined
in the Rights Agreement) shall occur, as a result of (i) the execution, delivery
or performance of the Merger Agreement (or any amendments thereto) or the
consummation of the transactions contemplated thereby, including, without
limitation, the Offer and the Merger, (ii) the execution, delivery or
performance of the Stockholder Agreements (as defined below) or any amendments
thereto, or the consummation of the transactions contemplated thereby, (iii) the
announcement, making or commencement of the Offer or the announcement of the
Merger Agreement or the Stockholder Agreements, or (iv) the acquisition of
Beneficial Ownership (as such term is defined in the Rights

                                        2
<PAGE>   5

Agreement) of Shares or Rights pursuant to, or in connection with, the Merger
Agreement, the Stockholder Agreements or otherwise as a result of any of the
transactions contemplated by the Merger Agreement or the Stockholder Agreements,
including, without limitation, the Offer and the Merger; and (y) the Rights will
expire pursuant to the terms of the Rights Agreement immediately prior to the
Effective Time.

     The consummation of the Merger is subject to the satisfaction or waiver of
a number of conditions, including, if required, the approval of the Merger by
the requisite vote or consent of the stockholders. Under the DGCL, the
stockholder vote necessary to approve the Merger will be the affirmative vote of
at least a majority of the outstanding Shares, including Shares held by
Purchaser and its affiliates. If the Minimum Condition is satisfied and
Purchaser purchases at least a majority of the outstanding Shares in the Offer,
Purchaser will be able to effect the Merger without the affirmative vote of any
other stockholder. If at least 90% of the outstanding Shares are acquired in the
Offer, Purchaser will be able to effect the Merger pursuant to Section 253 of
the DGCL without prior notice to, or any action or vote by, any other
stockholder. In that event, Purchaser intends to effect the Merger as promptly
as practicable following the purchase of Shares in the Offer. If at least 90% of
the outstanding Shares are not acquired in the Offer, the Company will furnish
to stockholders a proxy or information statement containing detailed information
concerning the Merger and will call a special meeting to vote on the Merger.
Pursuant to the Merger Agreement, Parent and Purchaser have agreed to vote the
Shares acquired by them pursuant to the Offer in favor of the Merger. See
Section 12 below.

     The Merger Agreement and the Stockholder Agreements are more fully
described in Section 12 below. 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 below.

     THIS OFFER TO PURCHASE AND THE RELATED LETTER OF TRANSMITTAL CONTAIN
IMPORTANT INFORMATION WHICH SHOULD BE READ CAREFULLY BEFORE ANY DECISION IS MADE
WITH RESPECT TO THE OFFER.

1. TERMS OF THE OFFER

     Upon the terms and subject to the conditions of the Offer (including, if
the Offer is extended or amended, the terms and conditions of any such extension
or amendment), Purchaser will accept for payment and pay for (and thereby
purchase) any and all Shares validly tendered and not withdrawn in accordance
with Section 4 below prior to the Expiration Date. As used in the Offer, the
term "Expiration Date" means 12:00 midnight, New York City time, on Tuesday,
December 21, 1999, unless and until Purchaser, in accordance with the terms of
the Offer and the Merger Agreement, shall have extended the period of time
during which the Offer is open, in which event the term "Expiration Date" means
the latest time and date at which the Offer, as so extended, expires. As used in
this Offer to Purchase, "business day" has the meaning set forth in Rule
14d-1(c)(6) under the Securities Exchange Act of 1934, as amended (the "Exchange
Act").

     The Offer is conditioned upon, among other things, satisfaction of the
Minimum Condition. The Offer also is subject to certain other conditions set
forth in Section 14 below. Pursuant to the terms of the Merger Agreement,
Purchaser expressly reserves the right (but will not be obligated) to waive any
or all of the conditions of the Offer.

     Purchaser expressly reserves the right, subject to the terms of the Merger
Agreement and the applicable rules and regulations of the Commission, at any
time or from time to time, and regardless of whether or not any of the events
set forth in Section 14 hereof shall have occurred or shall have been determined
by Purchaser to have occurred, to (i) extend the period of time during which the
Offer is open, and thereby delay acceptance for payment of and payment for, any
Shares; (ii) terminate the Offer if any condition referred to in Section 14 has
not been satisfied prior to the Expiration Date or upon the occurrence of any
event specified in Section 14, and (iii) waive any conditions or otherwise amend
the Offer in any respect, in each case by giving oral or written notice to the
Depositary. Any extension, termination or amendment will be followed as promptly
as practical by public announcement, the announcement in the case of an
extension to be issued no later than 9:00 a.m., New York City time, on the next
business day after the previously scheduled Expiration Date. Without limiting
the manner in which Purchaser may choose to make any public announcement,
                                        3
<PAGE>   6

Purchaser will have no obligation to publish, advertise or otherwise communicate
any such announcement, other than by issuing a release to the Dow Jones News
Service or as otherwise required by law. The reservation by Purchaser of the
right to delay acceptance for payment of, or payment for, Shares is subject to
the provisions of Rule 14e-1(c) under the Exchange Act, which requires that
Purchaser pay the consideration offered or return the Shares deposited by or on
behalf of stockholders promptly after the termination or withdrawal of the Offer
or extend the period of time during which the offer is open and thereby delay
acceptance for payment of and payment for the Shares.

     Pursuant to the Merger Agreement, Purchaser expressly reserves the right to
increase the price per Share payable in the Offer or to make any other changes
in the terms and conditions of the Offer, except that without the written
consent of the Company, Purchaser shall not (i) decrease the Offer Price, change
the form of consideration payable in the Offer or decrease the number of Shares
sought, (ii) change the conditions to the Offer (other than to waive any
condition), (iii) impose additional conditions to the Offer, or (iv) amend any
other term of the Offer in any manner adverse to the holders of Shares. The
Merger Agreement provides that Purchaser may, from time to time, in its sole
discretion extend the Expiration Date, (w) to comply with the applicable rules,
regulations, interpretations and positions of the Commission or its staff, (x)
if any of the conditions to the Offer have not been satisfied, for the minimum
period of time necessary to satisfy such condition; (y) regardless of the number
of Shares tendered, on one or more occasions for an aggregate period of not more
than 10 business days beyond the latest Expiration Date permitted by clauses (w)
and (x); and (z) if all of the conditions to the Offer have been satisfied but
fewer than 90% of the Shares of Common Stock outstanding (determined on a fully
diluted basis) have been tendered in the Offer, for the minimum period of time
necessary until 90% of such Shares have been so tendered, but in no event later
than the tenth business day following the latest Expiration Date permitted by
clauses (w), (x) and (y) of this sentence. The Merger Agreement provides that
subject to the prior satisfaction or waiver of the conditions to the Offer,
Purchaser will accept for payment, and pay for, in accordance with the terms of
the Offer, Shares validly tendered and not properly withdrawn pursuant to the
Offer as promptly as practicable after the Expiration Date.

     If Purchaser makes a material change in the terms of the Offer or the
information concerning the Offer or waives a material condition of the Offer,
Purchaser will disseminate additional tender offer materials and extend the
Offer to the extent required by Rules 14d-4(c), 14d-6(d) and 14e-1 under the
Exchange Act. The minimum period during which the Offer must remain open
following material changes in the terms of the Offer or information concerning
the Offer, other than a change in price or a change in percentage of securities
sought, will depend upon the facts and circumstances then existing, including
the relative materiality of the changed terms or information. The staff of the
Commission has stated that an offer should remain open for a minimum of five
business days from the date the material change is first published, sent or
given to stockholders and, if the material changes are made with respect to
information that approaches the significance of price and the percentage of
securities sought, a period of up to ten business days may be required to allow
for adequate dissemination and investor response. The requirement to extend the
Offer will not apply to the extent that the number of business days remaining
between the occurrence of the change and the then-scheduled Expiration Date
equals or exceeds the minimum extension period that would be required because of
such amendment.

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

2. ACCEPTANCE FOR PAYMENT AND PAYMENT FOR SHARES

     Upon the terms and subject to the conditions of the Merger Agreement and
the Offer (including, if the Offer is extended or amended, the terms and
conditions of any such extension or amendment), Purchaser will accept for
payment and will pay for any and all Shares that are validly tendered on or
prior to the Expiration Date, and not properly withdrawn in accordance with
Section 4 below, as soon as practicable after the
                                        4
<PAGE>   7

Expiration Date. All questions as to the satisfaction of such terms and
conditions will be determined by Purchaser in its sole discretion, which
determination will be final and binding. Subject to the applicable rules of the
Commission and the Merger Agreement, Purchaser expressly reserves the right to
delay acceptance for payment of, or payment for, Shares in order to comply, in
whole or in part, with any other applicable law or government regulation. Any
such delays will be effected in compliance with Rule 14e-1(c) under the Exchange
Act (relating to a Purchaser's obligation to pay for or return securities
promptly after the termination or withdrawal of the Offer).

     In all cases, Shares accepted for payment pursuant to the Offer will be
paid for only after timely receipt by the Depositary of (i) certificates
evidencing such Shares or timely confirmation ("Book-Entry Confirmation") of the
book-entry transfer of such Shares into the Depositary's account at the
Depositary Trust Company (the "Book-Entry Transfer Facility") pursuant to the
procedures set forth in Section 3, (ii) a Letter of Transmittal (or a manually
signed facsimile thereof), properly completed and duly executed with any
required signature guarantees, or, in the case of a book-entry transfer, an
Agent's Message (as defined below), and (iii) any other documents required by
the Letter of Transmittal. See Section 3 below.

     The term "Agent's Message" means a message, transmitted by the Book-Entry
Transfer Facility to, and received by, the Depositary and forming part of a
Book-Entry Confirmation, which states that (i) such Book-Entry Transfer Facility
has received an express acknowledgment from the participant in such Book-Entry
Transfer Facility tendering Shares which are the subject of such Book-Entry
Confirmation, (ii) such participant has received and agrees to be bound by the
terms of the Letter of Transmittal, and (iii) Purchaser may enforce such
agreement against such participant.

     For purposes of the Offer, Purchaser will be deemed to have accepted for
payment (and thereby purchased) Shares properly tendered to Purchaser and not
withdrawn, if and when Purchaser gives oral or written notice to the Depositary
of Purchaser's acceptance of such Shares. In all cases, payment for Shares
accepted for payment pursuant to the Offer will be made by deposit of the
purchase price therefor with the Depositary, which will act as agent for
tendering stockholders for the purpose of receiving payment from Purchaser and
transmitting payment to tendering stockholders.

     If, for any reason, acceptance for payment of any Shares tendered pursuant
to the Offer is delayed, or Purchaser is unable to accept for payment Shares
tendered pursuant to the Offer, then, without prejudice to Purchaser's rights
under the Offer (but subject to Rule 14e-1(c) under the Exchange Act), the
Depositary may, nevertheless, on behalf of Purchaser, retain tendered Shares,
and such Shares may not be withdrawn, except to the extent that the tendering
stockholders are entitled to exercise, and duly exercise, withdrawal rights as
described in Section 4 below. UNDER NO CIRCUMSTANCES WILL INTEREST BE PAID ON
THE OFFER PRICE TO BE PAID BY PURCHASER, REGARDLESS OF ANY EXTENSION OF THE
OFFER OR ANY DELAY IN MAKING SUCH PAYMENT.

     If any tendered Shares are not purchased pursuant to the Offer for any
reason or if certificates are submitted for more Shares than are tendered,
certificates for Shares not purchased or tendered will be returned pursuant to
the instructions of the tendering stockholder without expense to the tendering
stockholder (or, in the case of Shares delivered by book-entry transfer into the
Depositary's account at the Book-Entry Transfer Facility pursuant to the
procedures set forth in Section 3 below, the Shares will be credited to an
account maintained at the Book-Entry Transfer Facility) as promptly as
practicable following the expiration or termination of the Offer.

     If, prior to the Expiration Date, Purchaser increases the consideration to
be paid per Share pursuant to the Offer, Purchaser will pay the increased
consideration for all Shares purchased pursuant to the Offer, whether or not
such Shares were tendered prior to the increase in consideration.

3. PROCEDURE FOR TENDERING SHARES

     Valid Tenders. For a stockholder validly to tender Shares pursuant to the
Offer, either (i) a Letter of Transmittal (or a manually signed facsimile
thereof), properly completed and duly executed, together with any required
signature guarantees, or, in the case of a book-entry transfer, an Agent's
Message, and any other

                                        5
<PAGE>   8

required documents, must be received by the Depositary at one of its addresses
set forth on the back cover of this Offer to Purchase prior to the Expiration
Date and either (a) certificates evidencing Shares must be received by the
Depositary at any such address prior to the Expiration Date or (b) the Shares
must be delivered pursuant to the procedures for book-entry transfer set forth
below and a Book-Entry Confirmation must be received by the Depositary prior to
the Expiration Date; or (ii) the tendering stockholder must comply with the
guaranteed delivery procedures set forth below. No alternative, conditional or
contingent tenders will be accepted.

     Book-Entry Transfer. The Depositary will 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. 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 such transfer. However, although delivery of Shares may be
effected through book-entry transfer into the Depositary's account at a
Book-Entry Transfer Facility, the Letter of Transmittal (or a manually signed
facsimile thereof), properly completed and duly executed, with any required
signature guarantees, or an Agent's Message, and any other required documents,
must, in any case, be transmitted to, and received by, the Depositary at one of
its addresses set forth on the back cover of this Offer to Purchase prior to the
Expiration Date, or the tendering stockholder must comply with the guaranteed
delivery procedures described below. DELIVERY OF DOCUMENTS TO A BOOK-ENTRY
TRANSFER FACILITY IN ACCORDANCE WITH THE BOOK-ENTRY TRANSFER FACILITY'S
PROCEDURES DOES NOT CONSTITUTE DELIVERY TO THE DEPOSITARY.

     THE METHOD OF DELIVERY OF CERTIFICATES EVIDENCING SHARES, THE LETTER OF
TRANSMITTAL AND ANY OTHER REQUIRED DOCUMENTS IS AT THE OPTION AND SOLE RISK OF
THE TENDERING STOCKHOLDERS, 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.

     Signature Guarantees. No signature guarantee is required on the Letter of
Transmittal (i) if the Letter of Transmittal is signed by the registered
holder(s) (which term, for purposes of this Section, includes any participant in
any of the Book-Entry Transfer Facilities' systems whose name appears on a
security position listing as the owner of the Shares) of Shares tendered
therewith and such registered holder has not completed either the box entitled
"Special Delivery Instructions" or the box entitled "Special Payment
Instructions" on the Letter of Transmittal; or (ii) if such Shares are tendered
for the account of a financial institution (including most commercial banks,
savings and loan associations and brokerage houses) that is a participant in the
Security Transfer Agents Medallion Program, the New York Stock Exchange
Medallion Signature Guarantee Program or the Stock Exchange Medallion Program
(an "Eligible Institution"). In all other cases, all signatures on the Letter of
Transmittal must be guaranteed by an Eligible Institution. See Instruction 1 of
the Letter of Transmittal. If the certificates representing Shares are
registered in the name of a person other than the signer of the Letter of
Transmittal or if payment is to be made or certificates for Shares not tendered
or not accepted for payment are to be returned to a person other than the
registered holder of the certificates surrendered, then the tendered
certificates evidencing Shares must be endorsed or accompanied by appropriate
stock powers, in each case signed exactly as the name or names of the registered
holder or owners appear on the certificates, with the signatures on the
certificates or stock powers guaranteed as described above and as provided in
the Letter of Transmittal. See Instructions 1 and 5 of the Letter of
Transmittal.

     Guaranteed Delivery. If a stockholder desires to tender Shares pursuant to
the Offer and such stockholder's certificates for Shares are not immediately
available or the procedure for book-entry transfer

                                        6
<PAGE>   9

cannot be completed on a timely basis or time will not permit all required
documents to reach the Depositary prior to the Expiration Date, such
stockholder's tender may be effected if all the following conditions are met:

          (i) such tender is made by or through an Eligible Institution;

          (ii) a properly completed and duly executed Notice of Guaranteed
     Delivery, substantially in the form provided by Purchaser, is received by
     the Depositary (as provided below) prior to the Expiration Date; and

          (iii) the certificates for all tendered Shares in proper form for
     transfer (or a Book-Entry Confirmation with respect to all such tendered
     Shares) together with a properly completed and duly executed Letter of
     Transmittal (or a manually signed facsimile) 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 National Market trading days after
     the date of execution of the Notice of Guaranteed Delivery.

     The Notice of Guaranteed Delivery may be delivered by hand or transmitted
by telegram, facsimile transmission or mailed to the Depositary and must include
a guarantee by an Eligible Institution in the form set forth in the Notice of
Guaranteed Delivery.

     Notwithstanding any other provision of this Offer to Purchase, payment for
Shares accepted for payment pursuant to the Offer will in all cases be made only
after timely receipt by the Depositary of (i) certificates for the Shares or a
timely Book-Entry Confirmation with respect to such Shares, (ii) a Letter of
Transmittal (or a manually signed facsimile), 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 (iii) any other documents
required by the Letter of Transmittal. Accordingly, tendering stockholders may
be paid at different times depending upon when certificates for Shares or
Book-Entry Confirmations are actually received by the Depositary.

     Determination of Validity. All questions as to the form of documents and
the validity, eligibility (including time of receipt) and acceptance for payment
of any tender of Shares pursuant to any of the procedures described above will
be determined by Purchaser in its sole discretion, which determination shall be
final and binding on all parties. Purchaser reserves the absolute right to
reject any or all tenders of Shares determined not to be in proper form or the
acceptance of or payment for which may, in the opinion of Purchaser's counsel,
be unlawful. Purchaser also reserves the absolute right to waive any defect or
irregularity in any tender of any Shares of any particular stockholder whether
or not similar defects or irregularities are waived in the case of other
stockholders. Purchaser's interpretation of the terms and conditions of the
Offer (including the Letter of Transmittal and its instructions) will be final
and binding on all parties. No tender of Shares will be deemed to have been
validly made until all defects and irregularities have been cured or waived.
None of Purchaser, Parent, the Depositary, the Information Agent or any other
person will be under any duty to give notification of any defects or
irregularities in tenders or incur any liability for failure to give any such
information.

     Backup Federal Income Tax Withholding. To prevent backup federal income tax
withholding of 31% of the payments made to stockholders with respect to the
purchase price of Shares purchased pursuant to the Offer or the Merger, a
stockholder must provide the Depositary with his or her correct taxpayer
identification number and certify that he or she is not subject to backup
federal income tax withholding by completing the Substitute Form W-9 included in
the Letter of Transmittal. See Instruction 10 of the Letter of Transmittal. See
Section 5 below.

     Appointment as Proxy. By accepting a Letter of Transmittal, a tendering
stockholder irrevocably appoints designees of Purchaser as such stockholder's
attorneys-in-fact and proxies, with full power of substitution, in the manner
set forth in the Letter of Transmittal, to the full extent of such stockholder's
rights with respect to Shares tendered by such stockholder and purchased by
Purchaser and with respect to any and all other Shares or other securities
issued or issuable in respect of those Shares, on or after the date of the
Offer. All such powers of attorney and proxies will be considered coupled with
an interest in the tendered

                                        7
<PAGE>   10

Shares. Such appointment will be effective when, and only to the extent that,
Purchaser accepts for payment Shares tendered by such stockholder as provided
herein. Upon acceptance for payment, all prior powers of attorney, proxies or
consents given by the stockholder with respect to the Shares (and any other
Shares or other securities so issued in respect of such purchased Shares) will
be revoked, without further action, and no subsequent powers of attorney and
proxies may be given (and, if given, will not be deemed effective) by the
stockholder. The designees of Purchaser will be empowered to exercise all voting
and other rights of the stockholder with respect to such Shares (and any other
Shares or securities so issued in respect of such purchased Shares) as they in
their sole discretion may deem proper, including, without limitation, in respect
of any annual or special meeting of the stockholders, or any adjournment or
postponement of any such meeting, or in connection with any action by written
consent in lieu of any such meeting or otherwise (including any such meeting or
action by written consent to approve the Merger). Purchaser reserves the right
to require that, in order for Shares to be validly tendered, immediately upon
Purchaser's acceptance for payment of the Shares, Purchaser must be able to
exercise full voting and other rights of a record and beneficial owner with
respect to the Shares, including voting at any meeting of stockholders then
scheduled.

4. WITHDRAWAL RIGHTS

     Tenders of Shares made pursuant to the Offer are irrevocable, except as
otherwise provided in this Section 4. Shares tendered pursuant to the Offer may
be withdrawn pursuant to the procedures set forth below at any time prior to the
Expiration Date and, unless theretofore accepted for payment and paid for by
Purchaser pursuant to the Offer, may also be withdrawn at any time after January
20, 2000.

     For a withdrawal to be effective, a written, telegraphic or facsimile
transmission notice of withdrawal must be timely received by the Depositary at
one of its addresses set forth on the back cover of this Offer to Purchase. Any
such notice of withdrawal must specify the name of the persons who tendered the
Shares to be withdrawn, the number of Shares to be withdrawn and the name of the
registered holder, if different from that of the person who tendered the Shares.
If certificates evidencing Shares have been delivered or otherwise identified to
the Depositary, then, prior to the physical release of such certificates, the
tendering stockholder must also submit to the Depositary the serial numbers
shown on the particular certificates evidencing the Shares to be withdrawn, and
the signature on the notice of withdrawal must be guaranteed by an Eligible
Institution. If Shares have been tendered pursuant to the procedure for
book-entry transfer set forth in Section 3 above, the notice of withdrawal must
specify the name and number of the account at the Book-Entry Transfer Facility
to be credited with the withdrawn Shares and otherwise comply with such
Book-Entry Transfer Facility's procedures. Withdrawals of tenders of Shares may
not be rescinded, and any Shares properly withdrawn will be deemed not validly
tendered for purposes of the Offer. However, withdrawn Shares may be re-tendered
by again following any of the procedures described in Section 3 above 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 Purchaser, in its sole discretion,
whose determination will be final and binding on all parties. No withdrawal of
Shares will be deemed to have been properly made until all defects and
irregularities have been cured or waived. None of Parent, Purchaser, the
Depositary, the Information Agent or any other person will be under any duty to
give notification of any defects or irregularities in any notice of withdrawal
or incur any liability for failing to give such notification.

5. CERTAIN FEDERAL INCOME TAX CONSEQUENCES OF THE OFFER AND THE MERGER

     The following is a summary of the principal federal income tax consequences
of the Offer and the Merger to holders whose Shares are purchased pursuant to
the Offer or whose Shares are converted into the right to receive the Merger
Consideration in the Merger (including any cash amounts received by dissenting
stockholders pursuant to the exercise of appraisal rights). This discussion is
based upon the provisions of the Internal Revenue Code of 1986, as amended (the
"Code"), the applicable Treasury Regulations promulgated and proposed
thereunder, judicial authority and administrative rulings and practice.
Legislative, judicial or administrative rulings or interpretations are subject
to change, possibly on a retroactive basis, at any time and therefore could
alter or modify the statements and conclusions set forth below. It is assumed
that the Shares
                                        8
<PAGE>   11

are held as "capital assets" within the meaning of Section 1221 of the Code
(i.e., property held for investment). This discussion does not address all
aspects of federal income taxation that may be relevant to a particular
stockholder in light of such stockholder's personal investment circumstances, or
those stockholders subject to special treatment under the federal income tax
laws (for example, life insurance companies, tax-exempt organizations, foreign
corporations and nonresident alien individuals) or to stockholders who acquired
their Shares through the exercise of employee stock options or other
compensation arrangements. In addition, the discussion does not address any
aspect of foreign, state, local or estate and gift taxation that may be
applicable to a stockholder.

     Consequences of the Offer and the Merger to Stockholders. The receipt of
the Offer Price or the Merger Consideration, as the case may be (including any
cash amounts received by dissenting stockholders pursuant to the exercise of
appraisal rights), will be a taxable transaction for federal income tax purposes
(and also may be a taxable transaction under applicable state, local and other
income tax laws). In general, for federal income tax purposes, a stockholder
will recognize gain or loss equal to the difference between his adjusted tax
basis in the Shares sold pursuant to the Offer or converted to cash in the
Merger and the amount of cash received therefor. Gain or loss must be determined
separately for each block of Shares (i.e., Shares acquired at the same cost in a
single transaction) sold pursuant to the Offer or converted to cash in the
Merger. Such gain or loss will be capital gain or loss and will be long-term
gain or loss, if, on the date of sale (or, if applicable, the date of the
Merger), the Shares were held for more than one year.

     Backup Tax Withholding. Under the Code, a stockholder may be subject, under
certain circumstances, to "backup withholding" at a 31% rate with respect to
payments made in connection with the Offer or the Merger. Backup withholding
generally applies if the stockholder (i) fails to furnish such holder's social
security number or other taxpayer identification number ("TIN"), (ii) furnishes
an incorrect TIN, (iii) fails properly to report interest or dividends or (iv)
under certain circumstances, fails to provide a certified statement, signed
under penalties of perjury, that the TIN provided is such holder's correct
number and that such holder is not subject to backup withholding. Backup
withholding is not an additional tax but merely an advance payment, which may be
refunded to the extent it results in an overpayment of tax. Certain persons
generally are exempt from backup withholding, including corporations and
financial institutions. Certain penalties apply for failure to furnish correct
information and for failure to include the reportable payments in income. Each
stockholder should consult with such holder's own tax advisor as to such
holder's qualifications for exemption from withholding and the procedure for
obtaining such exemption.

     THE FOREGOING DISCUSSION MAY NOT BE APPLICABLE TO CERTAIN TYPES OF
STOCKHOLDERS, INCLUDING STOCKHOLDERS WHO ACQUIRED SHARES PURSUANT TO THE
EXERCISE OF EMPLOYEE STOCK OPTIONS OR OTHERWISE AS COMPENSATION, INDIVIDUALS WHO
ARE NOT CITIZENS OR RESIDENTS OF THE UNITED STATES, AND FOREIGN CORPORATIONS.

     THE FEDERAL INCOME TAX DISCUSSION SET FORTH ABOVE IS INCLUDED FOR GENERAL
INFORMATION ONLY AND IS BASED UPON PRESENT LAW. STOCKHOLDERS ARE URGED TO
CONSULT THEIR RESPECTIVE TAX ADVISORS WITH RESPECT TO THE SPECIFIC TAX
CONSEQUENCES OF THE OFFER AND THE MERGER TO THEM, INCLUDING THE APPLICATION AND
EFFECT OF THE ALTERNATIVE MINIMUM TAX, AND STATE, LOCAL AND FOREIGN TAX LAWS IN
VIEW OF THEIR OWN PARTICULAR CIRCUMSTANCES.

6. PRICE RANGE OF THE SHARES; DIVIDENDS ON THE SHARES

     From October 23, 1997 to May 5, 1999, the Shares were quoted on the Nasdaq
National Market under the symbol IVTC. Since May 5, 1999, the Shares have been
traded on the Nasdaq Over-the-Counter Bulletin Board market (the "OTC Bulletin
Board"). The following table sets forth, for each of the periods indicated,

                                        9
<PAGE>   12

the high and low sales price per Share as reported by the Nasdaq National
Market, and after May 5, 1999, by the OTC Bulletin Board.

  3rd Quarter...............................................    0.656     0.125
  4th Quarter (through November 19, 1999)...................    1.875     0.219
</TABLE>

     On November 18, 1999, the last full trading day prior to the public
announcement of the execution of the Merger Agreement, the closing sales price
per Share quoted on the OTC Bulletin Board was $1.25. On November 19, 1999, the
last full trading day prior to the date of this Offer to Purchase, the closing
sales price per Share quoted on the OTC Bulletin Board was $1.50. STOCKHOLDERS
ARE URGED TO OBTAIN CURRENT MARKET QUOTATIONS FOR THE SHARES.

     The Company has never declared or paid any cash dividend, and 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, STOCK QUOTATION AND
EXCHANGE ACT REGISTRATION

     The purchase of Shares pursuant to the Offer will reduce the number of
Shares that might otherwise trade publicly and the number of holders of Shares,
which could adversely affect the liquidity and market value of the remaining
Shares held by stockholders other than Purchaser.

     Although the Shares are currently registered under the Exchange Act, that
registration may be terminated upon application of the Company to the Commission
if the Shares are no longer held by 300 or more holders of record. If, as a
result of the purchase of Shares pursuant to the Offer, the Shares are no longer
held by 300 or more holders of record and the Company terminates the
registration of the Shares under the Exchange Act, the Shares will no longer
meet the requirements of the NASD for continued inclusion in the OTC Bulletin
Board. It is possible that the Shares would continue to trade in the local
over-the-counter market and that price quotations would be reported by other
sources, depending upon the interest in maintaining a market in the Shares on
the part of securities firms and other factors. Termination of the registration
of the Shares under the Exchange Act would substantially reduce the information
required to be furnished by the Company to holders of Shares and to the
Commission and would make certain of the provisions of the Exchange Act no
longer applicable to the Company. Such provisions include the short-swing profit
recovery provisions of Section 16(b), the requirement of furnishing a proxy
statement pursuant to Section 14(a) in connection with a stockholders' meeting
and the related requirement of providing an annual report to stockholders and
the requirements of Rule 13e-3 under the Exchange Act with respect to "going
private" transactions. Furthermore, "affiliates" of the Company and persons
holding "restricted securities" of the Company may be deprived of the ability to
dispose of such securities pursuant to Rule 144 as promulgated under the
Securities Act of 1933, as amended (the "Securities Act"). Purchaser intends to
seek to cause the Company to apply for termination of registration of the Shares
under the Exchange Act as soon after the completion of the Offer as the
requirements for such termination are met. If registration of the Shares is not
terminated prior to the Merger, then the registration of the Shares under the
Exchange Act will be terminated following consummation of the Merger.

     The Offer is not conditioned upon any financing arrangements. Purchaser
estimates that the total amounts of funds required to consummate the Offer, to
pay certain indebtedness and other obligations of the Company pursuant to the
Merger Agreement, to consummate the Merger and to pay related fees and expenses
will be approximately $105 million. Purchaser will obtain all such funds from
Parent in the form of capital contributions and/or loans. Parent will in turn

11. BACKGROUND OF THE OFFER

     On June 23, 1999, Rick Johnson, Vice President of Business Development for
Parent, telephoned William E. Haynes, Chairman and Chief Executive Officer of
the Company, stating that he desired to meet with officers of the Company to
explore potential mutual opportunities. Charles F. Schugart, President of the
Company, returned the call on behalf of the Company resulting in Mr. Johnson and
Mr. Schugart agreeing to meet, along with other officers of each company, on
June 30, 1999.

     On June 30, 1999, George Shedlarski, Vice President of Parent and
President -- Flow Solutions Division, and Mr. Johnson met with Mr. Schugart and
Pliny L. Olivier, Senior Vice President of Operations of the Company, to discuss
each company's business philosophy and the current operating environment, and to
generally explore any similarities or complementary strengths of their
respective businesses. Following the meeting the parties executed a
confidentiality agreement and agreed to exchange selected information relative
to the Company's current and projected operations. The conversations were
general in nature and did not involve price.

     On July 22, 1999, Mr. Shedlarski, Mr. Johnson, John Wood, Director of
Corporate Development for Parent, and Ronald F. Shuff, Vice President, Secretary
and General Counsel of Parent, contacted Simmons, and expressed an interest in
further exploring a potential business combination between Parent and the
Company. Following the call, Parent received a detailed information package from
Simmons to assist Parent in analyzing a potential merger with the Company as
well as to arrive at an initial valuation of the Company.

                                       13
<PAGE>   16

     On August 3, 1999, Messrs. Schugart, Olivier, Shedlarski and Johnson met to
discuss issues relating to a possible business combination between Parent and
the Company.

     On August 10, 1999, Mr. Johnson received a facsimile letter from Simmons
requesting a preliminary indication of Parent's interest in writing, including a
specific value for the Company.

     On August 16, 1999, Mr. Johnson sent a letter to Simmons expressing a
strong interest in Parent acquiring the Company on a preliminary "full
enterprise" valuation basis, including the assumption of debt, in a general
valuation range. Mr. Schugart, Douglas R. Harrington, Jr., Chief Financial
Officer for the Company, and Simmons contacted Mr. Shuff to discuss the status
of senior management and the Company's board of directors approval, the impact
of supplier relationships on the valuation and the timing of due diligence.

     On August 27, 1999, Messrs. Schugart, Olivier, Harrington, Shedlarski,
Johnson, Shuff and Stephen A. Simone, Vice President Sales and
Operations -- Flow Solutions Division of Parent, met at the Company's offices in
Houston to discuss initial due diligence matters. Mr. Olivier and Mr. Simone
agreed to visit both Parent and the Company operating facilities during the
following two weeks in order to better understand how a business combination
might be effected and what operating synergies may exist between the two
businesses. Mr. Olivier subsequently visited Parent sites in Benecia and Los
Angeles, California, and Mr. Olivier and Mr. Simone jointly visited one Company
site in Sulphur, Louisiana and Company and Parent sites in Tampa, Florida,
Chicago, Illinois and Beaumont and Houston, Texas.

     From September 22 through September 24, 1999, Messrs. Schugart, Olivier,
Harrington, Simone, Robert A. Rhodes, Manager Sales and Operations -- Eastern
U.S., John Sawyer, Controller -- Flow Solutions Division, J.P. Easton, Manager
Service Operations -- U.S., and Andrew J. Beall, Vice President Sales -- Flow
Control Division, met in Houston to ascertain the benefits which could be
achieved from a combination of the Company and Parent.

     On October 8, 1999, Simmons and Messrs. Schugart, Harrington, Shuff and
Johnson met at Parent's offices in Dallas to discuss an acquisition proposal for
the Company. Parent's representatives indicated that Parent was interested in
pursuing a possible transaction and that, subject to satisfactory completion of
a due diligence review, Parent's valuation of the Company on an overall full
enterprise valuation of the Company, including the assumption of debt and
payment of transaction costs, was $95 million. Parent's representatives also
informed the Company's representatives and Simmons that subject to satisfactory
completion of a due diligence review and certain other conditions, including
negotiation of a definitive merger agreement and stockholder agreements, Parent
would be willing to pay $95 million on this full enterprise valuation basis in
cash for the Company, to be allocated between creditors and equity holders of
the Company based on the Company reaching settlement agreements with its
creditors.

     The parties agreed to reconvene, and on October 12, 1999, Messrs. Schugart,
Olivier, Harrington and Simmons met with Messrs. Shuff and Johnson at the
Company's offices in Houston where they discussed the concerns which Parent had
outlined and presented a counterproposal of $110 million on the same full
enterprise basis. Mr. Shuff and Mr. Johnson then spoke on the telephone with C.
Scott Greer, President and Chief Operating Officer of Parent, and ultimately
proposed a valuation of $105 million on this basis, subject to satisfactory
completion of due diligence and other conditions, including negotiation of a
definitive merger agreement. The Company's representatives informed Parent's
representatives that Parent's proposal was acceptable in principle, subject to
board approval.

     On October 19, 1999, Mr. Johnson sent a written proposal, via facsimile, to
Simmons confirming the valuation and preliminary terms and conditions of the
proposed merger of the Company and Parent.

     During the remainder of October and through mid-November of 1999, Parent,
along with its legal advisors, environmental consultant and independent
accountants, conducted a due diligence review of information provided by the
Company and conducted various interviews with members of the Company's
management.

     On October 21, 1999, Parent held a board meeting at which management
presented background information with regard to the Company, the strategic
rationale for the Merger, the status of negotiations, the

                                       14
<PAGE>   17

financial ramifications of the Merger and the proposed terms of the Merger. Upon
review of the information presented by management, Parent's board of directors
authorized management to attempt to negotiate a definitive merger agreement with
the Company on the proposed terms, subject to board approval.

     On October 22, 1999, legal counsel for Parent distributed a draft of the
Merger Agreement to the Company and its legal advisors, and on November 3, 1999,
legal counsel for Parent distributed a draft of the Stockholder Agreements to
the Company and its legal advisors. The parties and their legal advisors
continued to negotiate the terms of the Merger Agreement and Stockholder
Agreements from October 22, 1999 through November 17, 1999.

     On October 29, 1999, the Company and Parent entered into a letter agreement
pursuant to which the Company agreed to pay Parent the out-of-pocket expenses
incurred by it in connection with the proposed transaction if the Company
accepts a competing offer within six months of such date and the related
transaction is consummated. The letter agreement terminated upon the execution
of the Merger Agreement.

     On November 16, 1999, Parent's board of directors authorized the execution,
delivery and performance of the Merger Agreement, the Stockholder Agreements and
the transactions contemplated thereby.

     On November 17, 1999, representatives of the Company informed Parent that
the Board of the Company had approved the Offer, the Merger and the Stockholder
Agreements and authorized the execution, delivery and performance of the Merger
Agreement and the transactions contemplated thereby.

     On November 18, 1999, representatives of the Company informed Parent that
the Board of the Company had reconvened on the afternoon on November 17, 1999
and again on the morning of November 18, 1999 in order to address concerns
voiced by a stockholder of the Company, at which meetings the Board of the
Company reconfirmed its approval of the Offer, the Merger and the Stockholder
Agreements.

     On November 18, 1999, Parent, Purchaser and the Company executed and
delivered the Merger Agreement; Parent, Purchaser and the Selling Stockholders
executed and delivered the Stockholder Agreements; and Parent and the Company
each announced the signing of the definitive Merger Agreement.

     On November 22, 1999, pursuant to the terms of the Merger Agreement,
Purchaser commenced the Offer.

12. PURPOSE OF THE OFFER AND THE MERGER; PLANS FOR THE COMPANY; THE MERGER
    AGREEMENT; THE STOCKHOLDER AGREEMENTS; OTHER MATTERS

  Purpose of the Offer and the Merger

     The purpose of the Offer is for Parent to acquire a majority equity
interest in the Company and acquire control of the Board as a first step in
acquiring the entire equity interest in the Company. The purpose of the Merger
is for Parent to acquire all Shares not purchased pursuant to the Offer. Upon
consummation of the Merger, the Company will become a wholly-owned subsidiary of
Parent. The Offer is being made pursuant to the Merger Agreement.

     Under the DGCL, the approval of the Board and the affirmative vote of the
holders of a majority of the outstanding Shares is required to approve and adopt
the Merger Agreement and the transactions contemplated thereby, including the
Merger. The Board has unanimously approved and adopted the Merger Agreement and
the transactions contemplated thereby. Thus, the only remaining required
corporate action of the Company is the approval and adoption of the Merger
Agreement and the transactions contemplated thereby by the affirmative vote of
the holders of a majority of the Shares. ACCORDINGLY, IF THE MINIMUM CONDITION
IS SATISFIED, PURCHASER WILL HAVE SUFFICIENT VOTING POWER TO CAUSE THE APPROVAL
AND ADOPTION OF THE MERGER AGREEMENT AND THE TRANSACTIONS CONTEMPLATED THEREBY
WITHOUT THE AFFIRMATIVE VOTE OF ANY OTHER STOCKHOLDER. FURTHER, IF AT LEAST 90%
OF THE OUTSTANDING SHARES ARE ACQUIRED IN THE OFFER, PURCHASER WILL BE ABLE TO
EFFECT THE MERGER PURSUANT TO SECTION 253 OF THE DGCL WITHOUT PRIOR NOTICE TO,
OR ANY ACTION OR VOTE BY, ANY OTHER STOCKHOLDER.

                                       15
<PAGE>   18

     In the Merger Agreement, the Company has agreed to convene a meeting of
stockholders as promptly as practicable following the consummation of the Offer
for the purpose of considering and taking action on the Merger Agreement and the
transactions contemplated thereby. Parent and Purchaser have agreed that all
Shares owned by them will be voted in favor of the Merger Agreement and the
transactions contemplated thereby.

  Plans for the Company

     Parent is conducting a detailed review of the Company and its assets,
business, corporate structure, capitalization, operations, properties, policies,
management and personnel to determine what business strategies it may pursue in
the event it acquires control of the Company. Such strategies are expected to
include, among other things, the integration of certain assets or businesses of
the Company with those of Parent and its subsidiaries, as well as the
implementation of industrial and technical savings and synergies created by the
transaction. Parent will make such changes or take such actions concerning the
Company only after it has completed its review and Parent's decisions could be
affected by information hereafter obtained, changes in general economic or
market conditions or in the business of the Company or its subsidiaries and
other factors.

     Assuming the Minimum Condition is satisfied and Purchaser purchases Shares
pursuant to the Offer, Parent intends to exercise promptly its rights under the
Merger Agreement to obtain majority representation on, and control of, the Board
of Directors of the Company. See "-- The Merger Agreement -- Board
Representation" below. Parent will exercise such rights by causing the Company
to appoint or elect to the Company Board Bernard G. Rethore, C. Scott Greer,
Hugh K. Coble, Diane C. Harris, Gregory T. Haymaker, Jr., Michael F. Johnson,
Charles M. Rampacek, Renee J. Hornbaker and Ronald F. Shuff. Information with
respect to such directors is contained in Schedule I hereto. Following the
Merger, the Company's entire Board of Directors will initially consist of the
directors of Purchaser, as set forth in Schedule I hereto, and the executive
officers of Purchaser, as set forth in Schedule I hereto, will become the
executive officers of the Company.

  The Merger Agreement

     The following is a summary of the material terms of the Merger Agreement.
This summary is not a complete description of the terms and conditions of the
Merger Agreement and is qualified in its entirety by reference to the full text
of the Merger Agreement, which is incorporated by reference and a copy of which
has been filed with the Commission as an exhibit to the Schedule 14D-1. The
Merger Agreement may be examined, and copies obtained, as set forth in Section 8
above.

     The Offer. The Merger Agreement provides for the commencement of the Offer
and prescribes conditions to consummation of the Offer. Purchaser has expressly
reserved the right to increase the price per Share payable in the Offer or to
make any other changes in the terms and conditions of the Offer, except that
without the written consent of the Company, Purchaser has agreed that it will
not (i) decrease the Offer Price, change the form of consideration payable in
the Offer or decrease the number of Shares sought, (ii) change the conditions to
the Offer (other than to waive any condition), (iii) impose additional
conditions to the Offer or (iv) amend any other term of the Offer in any manner
adverse to the holders of Shares. The Merger Agreement provides that Purchaser
may, from time to time, in its sole discretion extend the Expiration Date, (w)
to comply with the applicable rules, regulations, interpretations and positions
of the Commission and its staff; (x) if any of the conditions to the Offer have
not been satisfied, for the minimum period of time necessary to satisfy such
condition; (y) regardless of the number of Shares tendered, on one or more
occasions for an aggregate period of not more than 10 business days beyond the
latest Expiration Date permitted by clauses (w) and (y) of this sentence; and
(z) if all of the conditions to the Offer have been satisfied but fewer than 90%
of the shares of Common Stock outstanding (determined on a fully diluted basis)
have been tendered in the Offer, for the minimum period of time necessary until
90% of such shares have been so tendered, but in no event later than the tenth
business day following the latest Expiration Date permitted by clauses (w), (x)
and (y) of this sentence.

                                       16
<PAGE>   19

     Board Representation. The Merger Agreement provides that effective upon the
payment by Purchaser for Shares pursuant to the Offer, Purchaser shall be
entitled to designate the number of directors, rounded up to the next whole
number, on the Board that equals the product of (i) the total number of
directors on the Board (giving effect to the election or appointment of any
additional directors pursuant to the terms of the Merger Agreement) and (ii) the
percentage that the number of Shares beneficially owned by Parent and Purchaser
(including Shares accepted for payment) bears to the total number of Shares
outstanding. The Company has agreed that it will take all actions necessary to
cause Purchaser's designees to be elected or appointed to the Board, including,
without limitation, by increasing the size of the Board, amending its Bylaws,
using its best efforts to obtain resignations of incumbent directors, and filing
with the Commission and mailing to stockholders the information required by
Section 14(f) of the Exchange Act and the rules promulgated thereunder. In the
event that Purchaser's designees are elected to the Board, until the Effective
Time, the Board shall have at least two directors who were directors on the date
of execution of the Merger Agreement, and the affirmative vote of a majority of
such directors shall be required to amend or terminate the Agreement by the
Company or exercise or waive any of the Company's rights thereunder.

     The Merger. The Merger Agreement provides that the Merger will be effected
at the Effective Time. Upon consummation of the Merger, the separate existence
of Purchaser shall cease and the Company shall continue as the surviving
corporation. The surviving corporation of the Merger is sometimes referred to
herein as the "Surviving Corporation." The Merger will become effective upon the
filing of the Certificate of Merger (the "Certificate of Merger") with the
Delaware Secretary of State or at such time thereafter as is agreed upon by the
parties and specified in the Certificate of Merger.

     Consideration to be Paid in the Merger. The Merger Agreement provides that
upon the terms and subject to the conditions in the Merger Agreement and in
accordance with the DGCL, at the Effective Time, by virtue of the Merger, each
Share issued and outstanding immediately prior to the Effective Time (excluding
Shares owned by the Company or by Parent, Purchaser or any other wholly-owned
subsidiary of Parent, and Dissenting Shares (as defined below)) shall be
converted into the right to receive the Offer Price, in cash, without interest.
Each share of common stock of Purchaser issued and outstanding immediately prior
to the Effective Time will, at the Effective Time, by virtue of the Merger and
without any action on the part of the holder thereof, be converted into and
become one validly issued, fully paid and nonassessable share of common stock of
the Surviving Corporation. Each Share issued and outstanding immediately prior
to the Effective Time that is owned by the Company, Parent, Purchaser or any
other wholly-owned subsidiary of Parent, automatically will be cancelled and
retired without payment of any consideration therefor and shall cease to exist.

     Dissenting Shares. Shares issued and outstanding immediately prior to the
Effective Time held by a holder (if any) who has the right to demand, and who
properly demands, an appraisal of such Shares in accordance with Section 262 of
the DGCL (or any successor provision) ("Dissenting Shares") will not be
converted into the right to receive the Merger Consideration unless such holder
fails to perfect or otherwise loses such holder's right to such appraisal, if
any. If, after the Effective Time, such holder fails to perfect or loses any
such right to appraisal, each such Share of such holder shall be treated as a
Share that had been converted as of the Effective Time into the right to receive
the Merger Consideration in accordance with the terms of the Merger Agreement.

     Treatment of Stock Options, Warrants, Convertible Notes and Subsidiary
Acquisition Agreements. The Merger Agreement provides that the Company will use
its best efforts to cause each holder of an outstanding employee or director
stock option to purchase Shares (the "Stock Options") to enter into an Award
Termination Agreement (as defined in the Merger Agreement), pursuant to which
each outstanding Stock Option shall be canceled in exchange for a cash payment
of an amount equal to the excess, if any, of the Offer Price over the exercise
price per share of Common Stock subject to such Stock Option, multiplied by the
number of Shares of Common Stock subject to such Stock Option immediately prior
to its cancellation; provided, however, that the Company will not be in breach
of the Merger Agreement if it fails to secure Award Termination Agreements from
the holders of Stock Options for not more than an aggregate of 200,000 shares
(such Stock Options being the "Converted Options"). If there is no excess of the
Offer Price over the exercise price per share of Common Stock subject to a Stock
Option other than a Converted Option,
                                       17
<PAGE>   20

such Stock Option shall be canceled for no consideration. Notwithstanding the
foregoing, at the Effective Time, each Converted Option, whether vested or
unvested, shall be deemed to constitute an option (a "New Parent Option"), to
acquire, on the same terms and conditions as were applicable under such
Converted Option, the number of shares of common stock of Parent (the "Parent
Common Stock") (rounded down to the nearest whole number) equal to the product
of (A) the number of Shares of Common Stock issuable upon exercise of such
Converted Option and (B) the Offer Price divided by the average closing sale
price of the Parent Common Stock on the New York Stock Exchange Composite Tape
(as reported by The Wall Street Journal (Southwestern Edition)) for the ten
consecutive trading days immediately prior to and including the date preceding
the Effective Time (such product being the "Option Exchange Ratio"), at an
exercise price (rounded to the nearest whole cent) equal to (X) the exercise
price per share at which Common Stock shall have been purchasable immediately
prior to the Merger pursuant to such Converted Option divided by (Y) the Option
Exchange Ratio.

     The Merger Agreement provides that at any time after payment for Shares
pursuant to the Offer and prior to the Effective Time (but in no event later
than January 31, 2000 if Purchaser has accepted Shares for payment pursuant to
the Offer prior to such date), as determined by Purchaser, the parties shall
take the actions necessary to cause each outstanding warrant to purchase Shares
(the "Warrants") to be surrendered and canceled by the holders thereof and that
Purchaser shall pay, or provide the funds and cause the Company to pay, all
amounts due under the Loan Agreement (as defined in the Merger Agreement)
pursuant to which the Warrants were issued.

     The Merger Agreement provides that at any time after payment for Shares
pursuant to the Offer and prior to the Effective Time (but in no event later
than January 31, 2000 if Purchaser has accepted Shares for payment pursuant to
the Offer prior to such date), as determined by Purchaser, Purchaser shall pay,
or provide the funds and cause the Company to pay, the Convertible Notes (as
defined in the Merger Agreement).

     The Merger Agreement provides that at any time after payment for Shares
pursuant to the Offer and prior to the Effective Time (but in no event later
than January 31, 2000 if Purchaser has accepted Shares for payment pursuant to
the Offer prior to such date), as determined by Purchaser, Purchaser shall pay,
or provide the funds and cause the Company to pay, the amounts outstanding under

Subsidiary Acquisition Agreements or the Convertible Notes; or (q) enter into an

     No Solicitation. The Merger Agreement provides that the Company shall not,
nor shall it permit any of its subsidiaries to, nor shall it authorize or permit
any officer, director or employee of the Company or any of its subsidiaries or
any investment banker, financial advisor, attorney, accountant or other
representative or agent retained by the Company or any subsidiary (collectively,
the "Company Representatives") to, directly or indirectly, (i) solicit, initiate
or knowingly encourage the submission of any Acquisition Proposal (as defined
below) or (ii) participate in any discussions or negotiations regarding, or
furnish to any person any nonpublic information with respect to, or take any
other action designated or reasonably likely to facilitate any inquiries or the
making of any proposal that constitutes an Acquisition Proposal; provided,
however, that the Company may, in response to an unsolicited Acquisition
Proposal received after the date of the Merger Agreement, and subject to
compliance with Section 5.3(c) of the Merger Agreement, participate in
discussions or negotiations with a third party making an Acquisition Proposal
(and may furnish information to such third party pursuant to a customary
confidentiality agreement on terms no less favorable to the Company than the
confidentiality agreement between the Company and Parent) if (x) the Board of
Directors of the Company reasonably determines that the Acquisition Proposal is
a bona fide Superior Proposal (as defined below) and (y) the Board of Directors
determines (after consultation with independent outside counsel) that failing to
take such action could reasonably be determined to constitute a breach of its
fiduciary duties to the Company's stockholders under applicable law. The Merger
Agreement requires the Company to immediately cease and cause to be terminated
any existing solicitation, initiation, encouragement, activity, discussion or
negotiation with any person conducted prior to the execution of the Merger
Agreement by the Company or any Company Representative with respect to any
Acquisition Proposal existing on the date of the Merger Agreement. The Company
may not release any third party from, or amend or waive any provision of, any
standstill agreement to which it is a party unless the Board of Directors of the
Company determines (after consultation with independent outside counsel) that
failing to take such action could reasonably be determined to constitute a
breach of its fiduciary duties to the Company's stockholders under applicable
law. Any violation of the foregoing restrictions by any Company Representative
shall be deemed to be a breach by the Company. For purposes of the Merger
Agreement, "Acquisition Proposal" means any inquiry, proposal or offer from any
person relating to any direct or indirect acquisition or purchase of a
substantial amount of assets of the Company and its subsidiaries, taken as a
whole (other than the purchase of the Company's products in the ordinary course
of business), or of over 10% of any class of equity securities of the Company or
any of its subsidiaries or any tender offer or exchange offer that if
consummated would result in any person beneficially owning 10% or more of any
class of equity securities of the Company or any of its subsidiaries or any
merger, consolidation, business combination, sale of substantially all the
assets, recapitalization, liquidation, dissolution or similar transaction
involving the Company or any of its subsidiaries, other than the transactions

                                       20
<PAGE>   23

contemplated by the Merger Agreement, or any other transaction the consummation
of which could reasonably be expected to impede, interfere with, prevent or
materially delay the Offer or the Merger or which would reasonably be expected
to dilute materially the benefits to Parent of the transactions contemplated by
the Merger Agreement.

     Except as set forth in Section 5.3 of the Merger Agreement, neither the
Board of Directors of the Company nor any committee thereof may (i) withdraw or
modify, or propose to withdraw or modify, in a manner adverse to Parent, the
approval or recommendation by such Board of Directors or such committee of the
Offer, the Merger or the Merger Agreement, (ii) approve or recommend, or propose
publicly to approve or recommend, any Acquisition Proposal or (iii) cause the
Company to enter into any letter of intent, agreement in principle, acquisition
agreement or other similar agreement (each, an "Acquisition Agreement") related
to any Acquisition Proposal. Notwithstanding the foregoing, prior to the time of
acceptance for payment of Shares in the Offer, the Board of Directors of the
Company may (subject to the terms of this and the following sentence) withdraw
or modify its approval or recommendation of the Offer, the Merger Agreement or
the Merger, approve or recommend a Superior Proposal, or enter into an agreement
with respect to a Superior Proposal, in each case at any time after the second
business day following Parent's receipt of written notice advising Parent that
the Board of Directors of the Company has received a Superior Proposal,
specifying the material terms and conditions of such Superior Proposal and
identifying the person making such Superior Proposal; provided, that the Board
of Directors of the Company shall have determined (and been advised in writing
by independent outside counsel) that the failure to take such action could
reasonably be determined to cause the Board of Directors of the Company to
violate its fiduciary duties to the Company's stockholders under applicable law;
and provided further, that the Company shall not enter into an Acquisition
Agreement with respect to a Superior Proposal unless the Company shall have
furnished Parent with written notice not later than noon (New York City time)
two days in advance of any date that it intends to enter into such agreement and
shall have caused its financial and legal advisors to negotiate with Parent to
make such adjustments in the terms and conditions of the Merger Agreement as
would enable the Company to proceed with the transactions contemplated therein
on such adjusted terms. In addition, if the Company proposes to enter into an
Acquisition Agreement with respect to any Acquisition Proposal, it shall
concurrently with entering into such agreement pay, or cause to be paid, to
Parent the Termination Fee as described below under "-- Fees and Expenses." For
purposes of the Merger Agreement, a "Superior Proposal" means any bona fide
Acquisition Proposal made by a third party (i) that is on terms which the Board
of Directors of the Company determines in its good faith judgment (based on
consultation with the Company's financial advisor) to be more favorable to the
Company's stockholders than the Offer and the Merger and (ii) for which
financing, to the extent required, is then committed or which, in the good faith
judgment of the Board of Directors of the Company, is capable of being obtained
by such third party.

     In addition to the obligations of the Company set forth above, the Company
shall promptly advise Parent orally and in writing of any request for nonpublic
information or of any Acquisition Proposal known to it, the material terms and
conditions of such request or Acquisition Proposal and the identity of the
person making such request or Acquisition Proposal. The Company will promptly
inform Parent of any material change in the details (including amendments or
proposed amendments) of any such request or Acquisition Proposal.

     Releases. The Merger Agreement provides that upon payment of the amounts
required pursuant to the Third Amendment to Loan Agreement (as defined by the
Merger Agreement), the Company shall deliver to Parent evidence of the
termination and release of all liens on any assets of the Company or any
subsidiary of the Company granted in connection with, and executed receipts,
payoff letters or similar documents executed by the Company's lenders under, the
Loan Agreement dated as of July 7, 1998, among the Company, Chase Bank of Texas,
National Association, as Agent, and certain other financial institutions therein
listed, as amended, each in form and substance reasonably satisfactory to Parent
and Parent's lenders (the "Releases").

     Fees and Expenses. The Merger Agreement provides that, except as described
below, all expenses incurred in connection with the Merger Agreement and the
transactions contemplated by the Merger Agreement will be paid by the party
incurring the expenses. If (x) the Board of Directors of the Company shall
terminate the Merger Agreement pursuant to Section 7.1(c)(ii) thereof (in
connection with entering into a definitive agreement relating to a Superior
Proposal), (y) the Board of Directors of Parent or Purchaser
                                       21
<PAGE>   24

shall terminate the Merger Agreement pursuant to Section 7.1(d)(iii) thereof (in
connection with the Board of Directors of the Company or any committee thereof
having withdrawn or modified in a manner adverse to Parent or Purchaser or
resolved to do so, or having approved or recommended any Acquisition Proposal or
the Company having entered into an Acquisition Agreement with respect to
Superior Proposal), or (z) prior to the termination of the Merger Agreement
(other than by the Board of Directors of the Company pursuant to Section
7.1(c)(i)or 7.1(c)(iii) of the Merger Agreement), an Acquisition Proposal shall
have been made and within 12 months of such termination, the same or another
Acquisition Proposal from the same or another party shall be accepted and the
related transaction consummated pursuant to a definitive agreement or otherwise,
the Company shall pay to Parent (concurrently with such termination, in the case
of clauses (x) or (y) above, and not later than two business days after the
Company takes any such action with respect to an Acquisition Proposal, in the
case of clause (z) above) an amount equal to $3.0 million plus an amount equal
to the fees and expenses incurred by Parent and Purchaser in connection with the
Offer, the Merger, the Merger Agreement and the consummation of the transactions
contemplated thereby (the "Termination Fee").

     Conditions to the Merger. Pursuant to the Merger Agreement, the obligation
of each party to effect the Merger is subject to the satisfaction or written
waiver on or prior to the closing date of the Merger of the following
conditions: (i) if required by applicable law to effect the Merger, the Merger
Agreement shall have been approved by the holders of a majority of the
outstanding Shares, in accordance with applicable law and the Company's
certificate of incorporation and bylaws; (ii) no law, statute, rule, executive
order, decree, regulation, temporary restraining order or preliminary or
permanent injunction or other order issued by any federal, state or local
government or any court, administrative agency or commission or other
governmental authority or agency, domestic or foreign (a "Governmental Entity")
shall be in effect which declares the Merger Agreement invalid or unenforceable
in any material respect or which prohibits consummation of the Merger, and all
governmental consents, orders and approvals required for the consummation of the
Merger and the other transactions contemplated by the Merger Agreement shall
have been obtained and shall be in effect at the Effective Time; (iii) Parent,
Purchaser or their affiliates shall have purchased Shares pursuant to the Offer;
and (iv) the applicable waiting period under the Hart-Scott-Rodino Antitrust
Improvements Act of 1976 (the "HSR Act") shall have expired or been terminated.

     Termination. The Merger Agreement may be terminated and the Offer and the
Merger may be abandoned at any time prior to the Effective Time (notwithstanding
any stockholder approval of the Merger) (a) by the mutual written consent of the
Board of Directors of Parent or Purchaser and the Board of Directors of the
Company; (b) by either of the Board of Directors of the Company or the Board of
Directors of Parent or Purchaser (i) if the Offer shall have expired without any
Shares being purchased therein; provided, however, that the right to terminate
the Merger Agreement pursuant to clause (b)(i) shall not be available to any
party whose failure to fulfill any obligation under the Merger Agreement has
been the cause of, or resulted in, the failure of Purchaser to purchase Shares
pursuant to the Offer on or prior to the date on which the Offer shall have
expired; or (ii) 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 best efforts to lift), which permanently restrains,
enjoins or otherwise prohibits the acceptance for payment of, or payment for,
Shares pursuant to the Offer or the Merger and such order, decree, ruling or
other action shall have become final and non-appealable; (c) by the Board of
Directors of the Company (i) if Parent, Purchaser or any of their affiliates
shall have failed to commence the Offer on or prior to five business days
following the date of the initial public announcement of the Offer; provided,
that the Company may not terminate the Merger Agreement pursuant to clause
(c)(i) if the Company is in material breach of the Merger Agreement; (ii) in
connection with entering into a definitive agreement in accordance with Section
5.3(b) of the Merger Agreement (described above under "No Solicitation"),
provided the Company has complied with all provisions thereof, including the
notice provisions therein, and that the Company makes simultaneous payment of
the Termination Fee; or (iii) if Parent or Purchaser shall have breached in any
material respect any of their respective representations, warranties, covenants
or other agreements contained in the Merger Agreement, which breach cannot be or
has not been cured within 30 days after the giving of written notice to Parent
or Purchaser, as applicable, except, in any case, for such breaches which are
not, in Parent's opinion, reasonably likely to affect adversely Parent's or
Purchaser's ability to complete the Offer or the Merger; (d) by
                                       22
<PAGE>   25

the Board of Directors of Parent or Purchaser (i) if, due to an occurrence that
if occurring after the commencement of the Offer would result in a failure to
satisfy any of the conditions to the Offer, Parent, Purchaser, or any of their
affiliates shall have failed to commence the Offer on or prior to five business
days following the date of the initial public announcement of the Offer;
provided, that neither Purchaser nor Parent may terminate the Merger Agreement
pursuant to clause (d)(i) if it is in material breach of the Merger Agreement;
(ii) if prior to the purchase of Shares pursuant to the Offer, the Company shall
have breached any representation, warranty, covenant or other agreement
contained in the Merger Agreement which would give rise to the failure of a
condition set forth below in paragraph (f) or (h) of Section 14 -- "Certain
Conditions of the Offer;" or (iii) if either Parent or Purchaser is entitled to
terminate the Offer as a result of the occurrence of any event set forth below
in paragraph (e) of Section 14 -- "Certain Conditions of the Offer."

     Indemnification. The Merger Agreement provides that for six years after the
Effective Time, the Surviving Corporation (or any successor to the 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 and expenses
(including reasonable fees and disbursements of counsel and judgments, fines,
losses, claims, liabilities and amounts paid in settlement (provided that any
such settlement is effected with the written consent of Parent or the Surviving
Corporation, which consent will not be unreasonably withheld)) arising out of
actions or omissions occurring at or prior to the Effective Time to the full
extent permitted under Delaware law (provided that such actions or omissions
were in compliance with the standards set forth under Delaware law, the
certificate of incorporation and the bylaws of the Company), subject to the
terms of the certificate of incorporation and the bylaws of the Company, all as
in effect at the date of the Merger Agreement; provided that, in the event any
claim or claims are asserted or made within such six-year period, all rights to
indemnification in respect of any such claim or claims shall continue until
disposition of any and all such claims; provided, further, that nothing therein
shall impair any rights or obligations of any present or former directors or
officers of the Company.

     The Merger Agreement provides that Parent or the Surviving Corporation
shall maintain the Company's existing officers' and directors' liability
insurance for a period of not less than six years after the Effective Time;
provided, that the Parent may substitute therefor policies of substantially
similar coverage and amounts containing terms no less favorable to such former
directors or officers; provided, further, that in no event shall the Company be
required to pay aggregate premiums for insurance in excess of 200% of the
aggregate premiums paid by the Company in 1999 on an annualized basis for such
purpose.

     The Merger Agreement provides that the foregoing indemnification provisions
are intended to benefit the Company and each of the Indemnified Parties.

     Stockholders Meeting. The Merger Agreement provides that if stockholder
approval of the Merger is required by law, the Company will convene a special
meeting of stockholders (the "Stockholders Meeting") as promptly as practicable
after the expiration of the Offer and payment for the Shares for the purpose of
considering and voting upon the Merger Agreement and the transactions
contemplated thereby, including the Merger. The Merger Agreement provides that
the Board of Directors of the Company will recommend that the holders of the
Shares vote in favor of and approve the Merger Agreement and the Merger at the
Stockholders Meeting. At the Stockholders Meeting, Parent and Purchaser shall
vote all Shares beneficially owned by them in favor of the adoption and approval
of the Merger Agreement and the Merger.

     Consents and Approvals. The Merger Agreement provides that each of the
parties to the Merger Agreement will use all reasonable efforts to take, or
cause to be taken, all actions, and to do, or cause to be done, all things
necessary, proper or advisable to consummate and make effective, in the most
expeditious manner practicable, the transactions contemplated by the Merger
Agreement, including, without limitation, obtaining any necessary third-party or
governmental consents and approvals. In case at any time after the Effective
Time any further action is necessary or desirable to carry out the purposes of
the Merger Agreement, the proper officers and directors of each party to the
Merger Agreement will take all such necessary action.

     Amendment and Modification. Pursuant to the Merger Agreement, the Merger
Agreement may be amended, modified or supplemented only by written agreement of
Parent, Purchaser and the Company at any time prior to the Effective Time;
provided, however, that, after the Merger Agreement is adopted by the
                                       23
<PAGE>   26

Company's stockholders, no such amendment or modification shall reduce the
amount or change the form of the consideration to be paid in the Merger.

  The Stockholder Agreements

     The following is a summary of the material terms of the Stockholder
Agreements. This summary is not a complete description of the terms and
conditions of the Stockholder Agreements and is qualified in its entirety by
reference to the full text of the Stockholder Agreements, which are incorporated
by reference and copies of which have been filed with the Commission as exhibits
to the Schedule 14D-1. The Stockholder Agreements may be examined, and copies
obtained, as set forth in Section 8 above. Capitalized terms not otherwise
defined herein or in the following summary shall have the meaning set forth in
the Stockholder Agreements.

     Concurrently with the execution and delivery of the Merger Agreement, and
in order to induce Parent and Purchaser to enter into the Merger Agreement, each
of the Selling Stockholders, who own in the aggregate approximately 32% of the
outstanding Shares, entered into a Stockholder Agreement with Purchaser.
Pursuant to the Stockholder Agreements, each Selling Stockholder has agreed to
validly tender in the Offer and not withdraw all Shares beneficially owned by
such Stockholder on the date of the Stockholder Agreement or subsequently
acquired by such Stockholder.

     Each Granting Stockholder has granted Purchaser an irrevocable option to
purchase all Shares owned by such Stockholder at $1.62 per Share, exercisable at
any time in whole or in part after (i) the occurrence of any event as a result
of which Parent is entitled to receive a Termination Fee under the Merger
Agreement or (ii) such Stockholder shall have breached certain specified
agreements contained in the Stockholder Agreement. Each such option shall be
exercisable until the later of (i) the date that is 90 days after the date such
option became exercisable, and (ii) the date that is ten days after the date
that all waiting periods under the HSR Act required for the purchase of such
Shares have expired or been terminated; provided, that if at the expiration of
such period there shall be in effect any injunction or other order issued by any
governmental entity prohibiting the exercise of such option, the exercise period
shall be extended until ten days after the date that no such injunction or order
is in effect.

     Each Selling Stockholder has agreed that at any meeting of the stockholders
of the Company or in connection with any written consent of the stockholders of
the Company, such Selling Stockholder will vote (or cause to be voted) all
Shares held of record or owned by such Selling Stockholder (i) in favor of the
Merger and the Merger Agreement and the Stockholder Agreements and (ii) against
any Acquisition Proposal and against any action or agreement that would impede
or frustrate the Stockholder Agreements or result in a breach in any respect of
any obligation or agreement of the Company under the Merger Agreement or which
would result in any of the conditions described in "The Merger
Agreement -- Conditions to the Merger" above or in Section 14 ("Certain
Conditions of the Offer") not being fulfilled. Each such Stockholder has
irrevocably granted to and appointed Purchaser as such Selling Stockholder's
proxy and attorney-in-fact to vote the Shares owned by such Selling Stockholder,
or grant a consent or approval in respect of such Shares, in the manner
specified above.

     Each Selling Stockholder has agreed that, except as provided by the Merger
Agreement and the Stockholder Agreement, such Selling Stockholder will not (i)
offer to transfer, transfer or consent to any transfer, (ii) enter into any
contract, option or other agreement or understanding with respect to any
transfer, (iii) grant any proxy, power-of-attorney or other authorization or
(iv) deposit into a voting trust or enter into a voting agreement or
arrangement, each with respect to any or all Shares owned by such Selling
Stockholder.

     Each Selling Stockholder has agreed that such Selling Stockholder shall not
encourage, solicit, initiate or participate in any way in any discussion or
negotiation with, or provide information or otherwise take any action to assist
or facilitate, any person concerning any Acquisition Proposal. Each Selling
Stockholder has agreed to cease any such existing activities and to immediately
communicate to Purchaser the terms of any Acquisition Proposal.

     Each Chapter 11 Stockholder has agreed to file, as soon as practicable
following public announcement by Parent of the execution of the Merger
Agreement, a petition with the Delaware Bankruptcy Court requesting

                                       24
<PAGE>   27

the approval of its Stockholder Agreement and the transactions contemplated
thereby. In addition, each Chapter 11 Stockholder has agreed to deliver a copy
of its petition to Purchaser's counsel for review prior to filing it with the
Delaware Bankruptcy Court and to notify Purchaser promptly of any action taken
by the Delaware Bankruptcy Court with respect to the approval of its Stockholder
Agreement or the confirmation of a plan or reorganization regarding such Chapter
11 Stockholder.

     Each Selling Stockholder has waived any rights of appraisal or rights to
dissent from the Merger.

     The Stockholder Agreement with respect to each Selling Stockholder shall
terminate upon the earliest of (i) the Effective Time of the Merger, and (ii)
termination of the Merger Agreement, unless either (A) Parent is or may be
entitled to receive a Termination Fee under the Merger Agreement following such
termination or (B) prior to such termination such Selling Stockholder has
breached certain specified agreements contained in the Stockholder Agreement.

  Other Matters

     Appraisal Rights. Holders of the Shares do not have appraisal rights in
connection with the Offer. However, if the Merger is consummated, holders of the
Shares at the Effective Time will have certain rights pursuant to the provisions
of Section 262 of the DGCL including the right to dissent and demand appraisal
of, and to receive payment in cash of the fair value of, their Shares. Under
Section 262 of the DGCL, dissenting stockholders of the Company who comply with
the applicable statutory procedures will be entitled to receive a judicial
determination of the fair value of their Shares (exclusive of any element of
value arising from the accomplishment or expectation of the Merger) and to
receive payment of such fair value in cash, together with a fair rate of
interest thereon, if any. Any such judicial determination of the fair value of
the Shares could be based upon factors other than, or in addition to, the price
per Share to be paid in the Merger or the market value of the Shares. The value
so determined could be more or less than the price per Share to be paid in the
Merger.

     THE FOREGOING SUMMARY OF THE RIGHTS OF DISSENTING STOCKHOLDERS UNDER THE
DGCL DOES NOT PURPORT TO BE A COMPLETE STATEMENT OF THE PROCEDURES TO BE
FOLLOWED BY STOCKHOLDERS DESIRING TO EXERCISE ANY APPRAISAL RIGHTS AVAILABLE
UNDER THE DGCL. THE PRESERVATION AND EXERCISE OF APPRAISAL RIGHTS REQUIRE STRICT
ADHERENCE TO THE APPLICABLE PROVISIONS OF THE DGCL.

     Rule 13e-3. 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. However, Rule
13e-3 will not be applicable to the Merger or any such other business
combination if (i) the Shares are deregistered under the Exchange Act prior to
the Merger or other business combination or (ii) the Merger or other business
combination is consummated within one year after the purchase of the Shares
pursuant to the Offer and the value of the consideration paid per Share in the
Merger or other business combination (measured at the time of consummation of
the Merger) is at least equal to the amount paid per Share in the Offer. If
applicable, Rule 13e-3 requires, among other things, that certain financial
information concerning the Company and certain information relating to the
fairness of the proposed transaction and the consideration offered to minority
stockholders in such transaction be filed with the Commission and disclosed to
stockholders prior to consummation of the transaction.

13. DIVIDENDS AND DISTRIBUTIONS

     If on or after the date of the Merger Agreement, the Company should (i)
split, combine or otherwise change the Shares or its capitalization, (ii) issue
or sell any additional securities of the Company or otherwise cause an increase
in the number of outstanding securities of the Company or (iii) acquire
currently outstanding Shares or otherwise cause a reduction in the number of
outstanding Shares, then, without prejudice to Purchaser's rights under Sections
1 and 14 hereof, Purchaser in its sole discretion, subject to the
                                       25
<PAGE>   28

terms of the Merger Agreement, may make such adjustments as it deems appropriate
in the Offer Price and other terms of the Offer.

     If, on or after the date of the Merger Agreement, the Company should
declare or pay any dividend on the Shares or make any distribution (including,
without limitation, cash dividends, the issuance of additional Shares pursuant
to a stock dividend or stock split, the issuance of other securities or the
issuance of rights for the purchase of any securities) with respect to the
Shares that is payable or distributable to Stockholders of record on a date
prior to the transfer to the name of Purchaser or its nominee or transferee on
the Company's stock transfer records of the Shares purchased pursuant to the
Offer, then, without prejudice to Purchaser's rights under Sections 1 and 14
hereof, any such dividend, distribution or right to be received by the tendering
Stockholders will be received and held by the tendering Stockholder and tendered
to the Depositary for the account of Purchaser, accompanied by appropriate
documentation of transfer. Pending such remittance and subject to applicable
law, Purchaser will be entitled to all rights and privileges as owner of any
such dividend, distribution or right and may withhold the entire Offer Price or
deduct from the Offer Price the amount or value thereof, as determined by
Purchaser in its sole discretion.

     Pursuant to the terms of the Merger Agreement, the Company is prohibited
from taking any of the actions described in the two preceding paragraphs, and
nothing in this Offer to Purchase shall constitute a waiver by Purchaser or
Parent of any of its rights under the Merger Agreement or a limitation of
remedies available to Purchaser or Parent for any breach of the Merger
Agreement, including termination of the Merger Agreement.

14. CERTAIN CONDITIONS OF THE OFFER

     Notwithstanding any other provisions of the Offer, Purchaser shall not be

<PAGE>   29

          (b) there shall be any statute, rule, regulation, judgment, order or
     injunction enacted, entered, enforced, promulgated or deemed applicable to
     the Offer or the Merger, or any other action shall be taken by any
     Governmental Entity, other than the application to the Offer or the Merger

     in clauses (i) through (v) of paragraph (a) above;

          (c) there shall have occurred (i) any general suspension of trading
     in, or limitation on prices for, securities on any national securities

          (d) there shall have occurred any material adverse change (or any

     Company and its subsidiaries, taken as a whole, other than any such change
     that is the result of cancellation of a distributor agreement or similar
     agreement from an original equipment manufacturer or other material
     supplier;

          (e) (i) the Board of Directors of the Company or any committee thereof
     shall have withdrawn or modified in a manner adverse to Parent or Purchaser

     Agreement or resolved to do so, or shall have approved or recommended any
     Acquisition Proposal, or (ii) the Company shall have entered into any
     Acquisition Agreement with respect to any Superior Proposal;

     Expiration Date of the Offer;

          (g) (i) any stockholder of the Company party to a Stockholder
     Agreement shall have failed to perform in any material respect any material

     with by it under the Merger Agreement; or

          (i) the Merger Agreement shall have been terminated in accordance with
     its terms;

          which, in the reasonable judgment of Parent or Purchaser, in any such
     case and regardless of the circumstances (unless such condition is caused
     by the action or inaction of Parent or Purchaser) giving rise to such
     condition makes it inadvisable to proceed with the Offer and/or with such
     acceptance for payment of or payment for Shares.

     The foregoing conditions are for the sole benefit of Parent and Purchaser
and may be asserted by Parent or Purchaser regardless of the circumstances
giving rise to any such condition or may be waived by Parent and Purchaser, in
whole or in part, at any time and from time to time in their sole discretion.
The failure by Parent or Purchaser at any time to exercise any of the foregoing
rights shall not be deemed a waiver of any such right and each such right shall
be deemed an ongoing right and may be asserted at any time and from time to
time.

                                       27
<PAGE>   30

     Purchaser acknowledges that the Commission believes that (i) if Purchaser
is delayed in accepting the Shares it must either extend the Offer or terminate
the Offer and promptly return the Shares and (ii) the circumstances in which a
delay in payment are permitted are limited and do not include unsatisfied
conditions of the Offer, except with respect to most required regulatory
approvals.

15. CERTAIN LEGAL MATTERS

     Except as described in this Section 15, based on a review of publicly
available filings made by the Company with the Commission and other publicly
available information concerning the Company, but without any independent
investigation, neither Purchaser nor Parent is aware of any license or
regulatory permit that appears to be material to the business of the Company and
its subsidiaries, taken as a whole, that might be adversely affected by
Purchaser's acquisition of Shares as contemplated in this Offer to Purchase or
of any approval or other action by any governmental authority that would be
required for the acquisition or ownership of Shares by Purchaser as contemplated
in this Offer to Purchase. Should any such approval or other action be required,
Purchaser and Parent presently contemplate that such approval or other action
will be sought, except as described below under "State Takeover Laws."

     Antitrust. Under the HSR Act and the rules that have been promulgated
thereunder by the Federal Trade Commission ("FTC"), certain acquisition
transactions may not be consummated unless certain information has been
furnished to the Antitrust Division of the Department of Justice (the "Antitrust
Division") and the FTC and certain waiting period requirements have been
satisfied. The acquisition of Shares pursuant to the Offer is subject to these
requirements.

     Parent expects to file a Notification and Report Form with respect to the
Offer under the HSR Act as soon as practicable following commencement of the
Offer. The waiting period under the HSR Act with respect to the Offer will
expire at 11:59 p.m., Washington, D.C. time, on the fifteenth day after the date
such form is filed, unless early termination of the waiting period is granted.
In addition, the Antitrust Division or the FTC may extend such waiting period by
requesting additional information or documentary material from Parent. If such
request is made with respect to the Offer, the waiting period related to the
Offer will expire at 11:59 p.m., Washington, D.C. time, on the tenth day after
substantial compliance by Parent with such request. With respect to each
acquisition, the Antitrust Division or the FTC may issue only one request for
additional information. In practice, complying with a request for additional
information or material can take a significant amount of time. Expiration or
termination of applicable waiting periods under the HSR Act is a condition to
Purchaser's obligation to accept for payment and pay for Shares tendered
pursuant to the Offer.

     The FTC and the Antitrust Division frequently scrutinize the legality under
the antitrust laws of transactions such as Purchaser's proposed acquisition of
the Company. At any time before or after Purchaser's purchase of Shares pursuant
to the Offer, the Antitrust Division or the FTC could take such action under the
antitrust laws as it deems necessary or desirable in the public interest,
including seeking to enjoin the purchase of Shares pursuant to the Offer or the
consummation of the Merger or seeking the divestiture of Shares acquired by
Purchaser or the divestiture of substantial assets of Parent or its subsidiaries
or the Company or its subsidiaries. Private parties may also bring legal action
under the antitrust laws under certain circumstances. There can be no assurance
that a challenge to the Offer on antitrust grounds will not be made or, if such
a challenge is made, of the results thereof.

     State Takeover Laws. A number of states throughout the United States have
enacted takeover statutes that purport, in varying degrees, to be applicable to
attempts to acquire securities of corporations that are incorporated or have
assets, stockholders, executive offices or places of business in those states.
In Edgar v. MITE Corp., the Supreme Court of the United States held that the
Illinois Business Takeover Act, which involved state securities laws that made
the takeover of certain corporations more difficult, imposed a substantial
burden on interstate commerce and therefore was unconstitutional. In CTS Corp.
v. Dynamics Corp. of America, however, the Supreme Court of the United States
held that a state may, as a matter of corporate law and, in particular, those
laws concerning corporate governance, constitutionally disqualify, a potential
acquiror from voting on the affairs of a target corporation without prior
approval of the remaining stockholders, provided that the laws were applicable
only under certain conditions.

                                       28
<PAGE>   31

     Section 203 of the DGCL limits the ability of a Delaware corporation to
engage in business combinations with "interested stockholders" (defined as any
beneficial owner of 15% or more of the outstanding voting stock of the
corporation) unless, among other things, the corporation's board of directors
has given its prior approval of either the business combination or the
transaction that resulted in the stockholder becoming an "interested
stockholder." The Company has represented in the Merger Agreement that it
approved the Merger Agreement, the Stockholder Agreements and the transactions
contemplated thereby, including the Offer and the Merger, and has taken all
necessary steps to render Section 203 of the DGCL inapplicable to the Merger
Agreement, the Stockholder Agreements and the transactions contemplated thereby,
including the Offer and the Merger.

     Neither Parent nor Purchaser has currently complied with any state takeover
statute or regulation. Should any person seek to apply any state takeover law,
Purchaser will take such action as then appears desirable, which may include
challenging the validity or applicability of any such statute in appropriate
court proceedings. In the event it is asserted that one or more state takeover
laws is applicable to the Offer or the Merger, and an appropriate court does not
determine that it is inapplicable or invalid as applied to the Offer, Purchaser
might be required to file certain information with, or receive approvals from,
the relevant state authorities. In addition, if enjoined, Purchaser might be
unable to accept for payment any Shares tendered pursuant to the Offer, or be
delayed in continuing or consummating the Offer and the Merger. In such case,
Purchaser may not be obligated to accept for payment any Shares tendered. See
Section 14.

16. FEES AND EXPENSES

     Purchaser has retained D.F. King & Co., Inc. to act as the Information
Agent, and Equiserve to act as the Depositary, in connection with the Offer.
Each of the Information Agent and the Depositary will receive reasonable and
customary compensation for its services, will be reimbursed for certain
reasonable out-of-pocket expenses and will be indemnified against certain
liabilities and expense in connection therewith, including certain liabilities
under the federal securities laws.

     Except as set forth above, Purchaser will not pay any fees or commissions
to any broker or dealer or other person for soliciting tenders of Shares
pursuant to the Offer. Brokers, dealers, commercial banks and trust companies
will be reimbursed by Purchaser for customary mailing and handling expenses
incurred by them in forwarding the offering materials to their customers.

17. MISCELLANEOUS

     The Offer is not being made to (nor will tenders be accepted from or on
behalf of) holders of Shares residing in any jurisdiction in which the making of
the Offer or the acceptance thereof would not be in compliance with the
securities, blue sky or other laws of the jurisdiction. However, Purchaser may,
in its discretion, take such action as it may deem necessary to make the Offer
in any jurisdiction and extend the Offer to holders of Shares in that
jurisdiction. In any jurisdiction where the securities, blue sky or other laws
require the Offer to be made by a licensed broker or dealer, the Offer will be
deemed to be made on behalf of Purchaser by one or more registered brokers or
dealers that are licensed under the laws of the jurisdiction.

     Purchaser and Parent have filed with the Commission the Schedule 14D-1
pursuant to Rule 14d-3 under the Exchange Act containing certain additional
information with respect to the Offer. The Schedule 14D-1 and any amendments to
the Schedule 14D-1, including exhibits, may be examined and copies may be
obtained from the principal office of the Commission in the manner set forth in
Section 8 above (except that they will not be available at the regional offices
of the Commission).

     NO PERSON HAS BEEN AUTHORIZED TO GIVE ANY INFORMATION OR MAKE ANY
REPRESENTATION ON BEHALF OF PURCHASER NOT CONTAINED IN THE OFFER TO PURCHASE OR

with any amendments or supplements thereto, constitute the "Offer").

     Upon the terms and subject to the conditions of the Offer (and if the Offer
is extended or amended, the terms of any such extension or amendment), subject
to, and effective upon, acceptance for payment of, and payment for, Shares
tendered with this Letter of Transmittal in accordance with the terms of the
Offer, the undersigned hereby sells, assigns and transfers to, or upon the order
of, Purchaser all right, title and interest in and to all of the Shares that are

Shares on or after November 22, 1999 (collectively, "Distributions"), and
irrevocably constitutes and appoints the Depositary the true and lawful agent
and attorney-in-fact of the undersigned with respect to such Shares (and all
Distributions), with full power of substitution (such power of attorney being
deemed to be an irrevocable power coupled with an interest), to (i) deliver
Certificates evidencing such Shares (and any and all Distributions)), or
transfer ownership of such Shares (and any and all Distributions) on the account
books maintained by the Book-Entry Transfer Facility, together, in any such
case, with all accompanying evidences of transfer and authenticity, to or upon
the order of Purchaser, upon receipt by the Depositary as the undersigned's

full power and authority to tender, sell, assign and transfer the Shares
tendered hereby (and any Distributions), and that, when the Shares are accepted

of value thereof, as determined by Purchaser in its sole discretion.

     The undersigned understands that the valid tender of Shares pursuant to any
one of the procedures described in Section 3 of the Offer to Purchase and in the

 (1) The number shown on this form is my correct Taxpayer Identification Number (or I am waiting for a number to be

     the IRS has notified me that I am no longer subject to backup withholding.
 CERTIFICATION INSTRUCTIONS -- You must cross out item (2) above if you have been notified by the IRS that you are
 subject to backup withholding because of underreporting interest or dividends on your tax return. However, if after
 being notified by the IRS that you are subject to backup withholding, you receive another notification from the IRS
 that you were no longer subject to backup withholding, do not cross out item (2). (Also see instructions in the
 enclosed guidelines.)

                                  INSTRUCTIONS

             FORMING PART OF THE TERMS AND CONDITIONS OF THE OFFER

     1. GUARANTEE OF SIGNATURES. Except as otherwise provided below, no
signature guarantee is required on this Letter of Transmittal (a) if this Letter
of Transmittal is signed by the registered holder(s) (which term, for the
purposes of this document, includes any participant in the Book-Entry Transfer
Facility whose name appears on a security position listing as the owner of the
Shares) of Shares tendered herewith and such registered holder has not completed
either the box entitled "Special Delivery Instructions" or the box entitled
"Special Payment Instructions" on this Letter of Transmittal or (b) if such
Shares are tendered for the account of a financial institution (including most
commercial banks, savings and loan associations and brokerage houses) that is a
participant in the Security Transfer Agents Medallion Program, the New York
Stock Exchange Medallion Signature Guarantee Program or the Stock Exchange
Medallion Program (an "Eligible Institution"). In all other cases, all
signatures on the Letter of Transmittal must be guaranteed by an Eligible
Institution. See Instruction 5. If the Certificates are registered in the name
of a person other than the signer of this Letter of Transmittal, or if payment
is to be made or delivered to, or Certificates evidencing unpurchased Shares are
to be issued or returned to, a person other than the registered owner, then the
tendered Certificates must be endorsed or accompanied by duly executed stock
powers, in either case signed exactly as the name or names of the registered
owner or owners appear on the Certificates, with the signatures on the
Certificates or stock powers guaranteed by an Eligible Institution as provided
in this Letter of Transmittal. See Instruction 5.

     2. DELIVERY OF LETTER OF TRANSMITTAL AND SHARES. This Letter of Transmittal
is to be used either if Certificates evidencing Shares are to be forwarded with
this Letter of Transmittal or, unless an Agent's Message is utilized, if
delivery of Shares is to be made pursuant to the procedures for book-entry
transfer set forth in Section 3 of the Offer to Purchase. Certificates for all
physically delivered Shares, or a confirmation of a book-entry transfer into the
Depositary's account at the Book-Entry Transfer Facility of all Shares delivered
electronically, as well as a properly completed and duly executed Letter of
Transmittal with any required signature guarantees (or facsimile thereof or, in
the case of a book-entry transfer, an Agent's Message) and any other documents
required by this Letter of Transmittal must be received by the Depositary at one
of its addresses set forth in this Letter of Transmittal on or prior to the
Expiration Date (as defined in the Offer to Purchase).

     Stockholders whose Certificates are not immediately available or who cannot
deliver their Certificates and all other required documents to the Depositary or
complete the procedures for book-entry transfer on or prior to the Expiration
Date may nevertheless 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) 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 Purchaser, must be received by the
Depositary prior to the Expiration Date, and (iii) Certificates for all
physically delivered Shares or a Book-Entry Confirmation with respect to all
Shares delivered electronically, as well as a properly completed and duly
executed Letter of Transmittal (or facsimile thereof), with any required
signature guarantees (or, in the case of 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 trading days
after the date of such Notice of Guaranteed Delivery. If Certificates are
forwarded separately to the Depositary, a properly completed and duly executed
Letter of Transmittal (or a manually signed facsimile) must accompany each
delivery.

     THE METHOD OF DELIVERY OF CERTIFICATES, THIS LETTER OF TRANSMITTAL AND ANY
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. 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.

                                        8
<PAGE>   9

     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 a facsimile), waive any right to receive any
notice of the acceptance of their Shares for payment.

     3. INADEQUATE SPACE. If the space provided in this Letter of Transmittal is
inadequate, the information required under "Description of Shares Tendered"
should be listed on a separate signed schedule attached to this Letter of
Transmittal.

     4. PARTIAL TENDERS (NOT APPLICABLE TO DELIVERY BY BOOK-ENTRY TRANSFER). If
fewer than all of the Shares represented by any Certificates delivered to the
Depositary with this Letter of Transmittal 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 cases, a new Certificate for the remainder of the Shares that
were evidenced by the old Certificate(s) will be sent, without expense, to the
person(s) signing this Letter of Transmittal, unless otherwise provided in the
appropriate box on this Letter of Transmittal, as soon as practicable after the
expiration or termination of the Offer. All Shares represented by Certificate(s)
delivered to the Depositary will be deemed to have been tendered unless
otherwise indicated.

     5. SIGNATURES ON LETTER OF TRANSMITTAL, INSTRUMENTS OF TRANSFER 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 Certificate(s) without
alteration, enlargement or any change whatsoever.

     If any of the Shares tendered hereby are owned of record by two or more
persons, all such persons must sign this Letter of Transmittal.

     If any of the Shares tendered hereby are registered in different names on
several Certificates, it will be necessary to complete, sign and submit as many
separate Letters of Transmittal as there are different registrations of
Certificates.

     If this Letter of Transmittal is signed by the registered holder(s) of the
Shares listed and transmitted hereby, no endorsements of Certificates or
separate instruments of transfer are required unless payment is to be made, or
Certificates not tendered or not purchased are to be issued or returned, to a
person other than the registered holder(s). Signatures on the Certificates or
instruments of transfer must be guaranteed by an Eligible Institution.

     If this Letter of Transmittal is signed by a person other than the
registered holder(s) of the Shares evidenced by the Certificate(s) listed and
transmitted hereby, the Certificates must be endorsed or accompanied by
appropriate instruments of transfer, in either case signed exactly as the
name(s) of the registered holder(s) appear on the Certificate(s). Signatures on
the Certificate(s) or instruments of transfer must be guaranteed by an Eligible
Institution.

     If this Letter of Transmittal or any Certificates or instruments of
transfer are signed by a trustee, executor, administrator, guardian,
attorney-in-fact, officer of a corporation or other person acting in a fiduciary
or representative capacity, that person should so indicate when signing, and
proper evidence satisfactory to Purchaser of that person's authority to so act
must be submitted.

     6. STOCK TRANSFER TAXES. Except as set forth in this Instruction 6,
Purchaser will pay or cause to be paid any stock transfer taxes with respect to
the transfer and sale of Shares to it or its order pursuant to the Offer. If,
however, payment of the purchase price of any Shares purchased is to be made to,
or (in the circumstances permitted hereby) if Certificates for Shares not
tendered or not purchased are to be registered in the name of, any person other
than the registered holder(s), or if a transfer tax is imposed for any reason
other than the sale or transfer of Shares to Purchaser pursuant to the Offer,
then the amount of any transfer taxes (whether imposed on the registered
holder(s), such other person or otherwise) payable on account of the transfer to
such other person will be deducted from the purchase price of such Shares
purchased, unless evidence satisfactory to Purchaser of the payment of such
taxes, or exemption therefrom, is submitted.

     7. SPECIAL PAYMENT AND DELIVERY INSTRUCTIONS. If a check for the purchase
price of any Shares tendered hereby is to be issued, or a Certificate evidencing
Shares not tendered or not purchased is to be issued in the
                                        9
<PAGE>   10

name of a person other than the person(s) signing this Letter of Transmittal or
if such check or any such Certificate is to be sent to someone other than the
person(s) signing this Letter of Transmittal or to the person(s) signing this
Letter of Transmittal at an address other than that shown on page 1, the
appropriate boxes on this Letter of Transmittal must be completed. Stockholders
tendering Shares by book-entry transfer may request that Shares not purchased be
credited to such account at the Book-Entry Transfer Facility as such stockholder
may designate under "Special Payment Instructions." If no such instructions are
given, any such Shares not purchased will be returned by crediting the account
at the Book-Entry Transfer Facility designated above.

     8. REQUESTS FOR ASSISTANCE OR ADDITIONAL COPIES. Questions and requests for
assistance may be directed to the Information Agent (as defined below) at its
address or telephone number set forth below and requests for additional copies
of the Offer to Purchase, 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 or brokers,
dealers, commercial banks and trust companies, and such materials will be
furnished at Purchaser's expense.

     9. WAIVER OF CONDITIONS. The conditions of the Offer may be waived by
Purchaser, in whole or in part, at any time or from time to time, in Purchaser's
sole discretion.

     10. BACKUP WITHHOLDING TAX. Under the federal income tax laws, the
Depositary will be required to withhold 31% of the amount of any payments made
to certain stockholders pursuant to the Offer. In order to avoid such backup
withholding, each tendering stockholder, and, if applicable, each other payee,
must provide the Depositary with such stockholder's or payee's correct taxpayer
identification number and certify that such stockholder or payee is not subject
to such backup withholding by completing the Substitute Form W-9 set forth on
page 7. In general, if a stockholder or payee is an individual, the taxpayer
identification number is the Social Security Number of such individual. If the
Depositary is not provided with the correct taxpayer identification number, the
shareholder or payee may be subject to a $50 penalty imposed by the Internal
Revenue Service. Certain stockholders or payees (including, among others, all
corporations and certain foreign individuals) are not subject to these backup
withholding and reporting requirements. In order to satisfy the Depositary that
a foreign individual qualifies as an exempt recipient, such stockholder or payee
must submit a statement, signed under penalties of perjury, attesting to that
individual's exempt status. Such statements can be obtained from the Depositary.
For further information concerning backup withholding and instructions for
completing the Substitute Form W-9 (including how to obtain a taxpayer
identification number if you do not have one and how to complete the Substitute
Form W-9 if Shares are held in more than one name), consult the enclosed
Guidelines for Certification of Taxpayer Identification Number on Substitute
Form W-9.

     Failure to complete the Substitute Form W-9 will not, by itself, cause
Shares to be deemed invalidity tendered, but may require the Depositary to
withhold 31% of the amount of any payments made pursuant to the Offer. Backup
withholding is not an additional federal income tax. Rather, the federal income
tax liability of a person 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 provided that the required information is furnished to
the Internal Revenue Service. NOTE: FAILURE TO COMPLETE AND RETURN THE
SUBSTITUTE FORM W-9 MAY RESULT IN BACKUP WITHHOLDING OF 31% OF ANY PAYMENTS MADE
TO YOU PURSUANT TO THE OFFER. PLEASE REVIEW THE ENCLOSED GUIDELINES FOR
CERTIFICATE OF TAXPAYER IDENTIFICATION NUMBER ON SUBSTITUTE FORM W-9 FOR
ADDITIONAL DETAILS.

     11. LOST OR DESTROYED CERTIFICATES. If any Certificate(s) representing
Shares has been lost, destroyed or stolen, the stockholder should promptly
notify the Depositary by checking the box immediately preceding the special
payment/special delivery instructions and indicating the number of Shares lost.
The Stockholders will then be instructed as to the steps that must be taken in
order to replace the Certificate(s). This Letter of Transmittal and related
documents cannot be processed until the procedures for replacing lost or
destroyed Certificates have been followed.

NEWS RELEASE

November 18, 1999

NEWS FROM:        FLOWSERVE CORPORATION

SUBJECT:          FLOWSERVE SIGNS AGREEMENT TO ACQUIRE
                  INVATEC FOR ABOUT $100 MILLION

FOR INFORMATION:  Crystal C. Bell (972) 443-6557

         DALLAS, TEXAS - Flowserve Corporation announces today that the Company
has signed a definitive agreement with Innovative Valve Technologies, Inc.
(Invatec) (NASDAQ: IVTC.OB) to acquire Invatec for about $100 million, including
the combined cost of purchased equity and assumed debt. It is expected that the
transaction will close in early January 2000.

         Under the agreement, Flowserve will issue a cash tender offer to
acquire the outstanding 9.7 million shares of the common stock of Invatec at a
price of $1.62 per share, or about $15.7 million. In addition, Flowserve will
assume Invatec's projected debt and related obligations of about $84.0 million,
plus certain transaction-related expenses.

         With reported 1998 revenues of $154.6 million, Invatec is engaged
principally in providing comprehensive maintenance, repair, replacement and
value-added distribution services for valves, piping systems, instrumentation
and other process-

system components for its industrial customers. Based in Houston, Invatec has 63
operating locations in the United States, 2 in Europe and 1 in the Middle East.

          "When we formed Flowserve about two years ago, we stated that a key
strategy for the new enterprise was to expand our service and repair
capabilities for our process-industry customers," said Bernard G. Rethore,
Flowserve Chairman and Chief Executive Officer. "The acquisition of Invatec will
represent a major step in achieving that vision. And, this transaction will
provide important synergies with our existing related operations - 90 service
and quick response centers around the world."

         "Invatec is an excellent strategic fit for Flowserve," said C. Scott
Greer, Flowserve President and Chief Operating Officer. "Through this
acquisition, we will significantly expand our technical service and repair
capabilities, as well as local facility presence for our customers. Importantly,
we expect that the addition of Invatec to Flowserve's operations will be
accretive in 2000. This acquisition will be a platform to significantly increase
our existing service business going forward."

         The agreement is subject to certain conditions, including the valid
tender of at least a majority of the shares of Invatec common stock without
withdrawal prior to the expiration of the tender offer, the expiration of
applicable waiting periods under federal antitrust law and the absence of a
material adverse change in Invatec's business conditions. Flowserve currently
expects these conditions to be satisfied.

         In related action, shareholders representing about 30 percent of the
outstanding Invatec common stock, including both the Chairman and the President
of Invatec, executed agreements with Flowserve to tender their shares in
response to

the forthcoming Flowserve tender offer, assuming certain expected approvals for
two corporate shareholders.

SAFE HARBOR STATEMENT: This news release contains various forward-looking
statements and includes assumptions about Flowserve's future market conditions,
operations and results. These statements are based on current expectations and
are subject to significant risks and uncertainties. They are made pursuant to
safe harbor provisions of the Private Securities Litigation Reform Act of 1995.
Among the many factors that could cause actual results to differ materially from
the forward-looking statements are: further changes in the already competitive
environment for the Company's products or competitors' responses to Flowserve's
strategies; the Company's ability to integrate Invatec into its management and
operations; political risks or trade embargoes affecting important country
markets; the health of the petroleum, chemical and power industries; economic
turmoil in areas outside the United States; continued economic growth within the
United States; unanticipated difficulties or costs or reduction in benefits
associated with the implementation of the Company's "Flowserver" business
process improvement initiative, including software; the impact of the "Year
2000" computer issue; and the recognition of significant expenses associated
with adjustments to realign the combined Company's facilities and other
capabilities with its strategies and business conditions.

affirmations may subject you to criminal penalties including fines and/or
imprisonment.

                          AGREEMENT AND PLAN OF MERGER

     This AGREEMENT AND PLAN OF MERGER (this "AGREEMENT"), dated as of November
18, 1999, by and between Flowserve Corporation, a New York corporation
("PARENT"), FORREST ACQUISITION SUB, INC., a Delaware corporation and a
wholly-owned subsidiary of Parent ("PURCHASER"), and Innovative Valve
Technologies, Inc., a Delaware corporation (the "COMPANY").

                             PRELIMINARY STATEMENTS

     A. The Boards of Directors of Parent, Purchaser and the Company have each
determined that it is advisable and in the best interests of their respective
stockholders for Parent to acquire the Company upon the terms and subject to the
conditions set forth herein.

     B. It is proposed that Purchaser shall make a cash tender offer (the
"OFFER") for all of the outstanding shares of common stock, par value $0.001 per
share, of the Company (the "COMMON STOCK") (such shares of Common Stock,together
with the Rights (as defined herein) associated with such shares, being
hereinafter referred to as the "SHARES") and that following consummation of the
Offer, Purchaser shall be merged (the "MERGER") with and into the Company, all
upon the terms and subject to the conditions set forth herein.

     C. As a condition and inducement to Parent's willingness to enter into this
Agreement, Purchaser and those stockholders of the Company listed on Schedule A
hereto are entering into a stockholder agreement dated as of the date of this
Agreement (the "STOCKHOLDER/OPTION AGREEMENT"), a form of which is attached
hereto as Exhibit A, pursuant to which each such stockholder, among other
things, agrees to tender in the Offer and not withdraw all Shares owned by such
stockholder, grants an irrevocable proxy to Purchaser's designees to vote all
Shares owned by such stockholder with respect to certain matters, and grants to
Purchaser an option to purchase all Shares owned by such stockholder at the
Offer Price under specified circumstances. In addition, those stockholders of
the Company listed on Schedule B hereto that have filed voluntary petitions for
reorganization under Chapter 11 of the U.S. Bankruptcy Code (the "CHAPTER 11
STOCKHOLDERS") are entering into stockholders agreements dated as of the date of
this Agreement (each, a "CHAPTER 11 STOCKHOLDER AGREEMENT," and together with
the Stockholder/Option Agreement, the "STOCKHOLDER AGREEMENTS"). The Chapter 11
Stockholder Agreements are similar to the Stockholder/Option Agreement but do
not contain an option provision and are subject to the earlier to occur of
approval of such Chapter 11 Stockholder Agreements by the Bankruptcy Court for
the District of Delaware (the "DELAWARE BANKRUPTCY COURT") or the confirmation
by the Delaware Bankruptcy Court of a plan of reorganization for the Chapter 11
Stockholder party thereto.

     NOW, THEREFORE, in consideration of the premises and mutual covenants
contained herein and for other good, valuable and binding consideration, the
receipt and sufficiency of which are hereby acknowledged, the parties hereto,
intending to be legally bound hereby, agree as follows:

                                   ARTICLE I.

                                THE TENDER OFFER

     SECTION 1.1  The Tender Offer. (a) Provided that this Agreement has not
been terminated in accordance with Article VII and none of the events referred
to in Annex A has occurred or is existing, as promptly as practicable, but in no
event later than five business days after the public announcement of the
execution of this Agreement by Parent and the Company, Purchaser shall, and
Parent shall cause Purchaser, to commence the Offer for all outstanding Shares
at a purchase price of $1.62 per Share (such amount, or any greater amount per
Share paid pursuant to the Offer, being the "OFFER PRICE"), net to the seller in
cash, without interest thereon. The Offer initially shall expire at 12:00
midnight New York City time on the twentieth business day following the date of
commencement of the Offer (such date and time, as extended in accordance with
the terms hereof, the "EXPIRATION DATE"). The obligation of Purchaser to accept
for payment, purchase, and pay for any Shares validly tendered and not withdrawn
pursuant to the Offer shall be subject only to the conditions set forth in Annex
A hereto (the "OFFER CONDITIONS") (any of which may be

                                        1
<PAGE>   5

waived in whole or in part by Purchaser in its sole discretion, provided that,
without the prior written consent of the Company, Purchaser shall not waive the
Minimum Condition (as defined in Annex A)). Purchaser specifically reserves the
right to increase the Offer Price and to make any other changes in the terms and
conditions of the Offer; provided that, unless previously approved by the
Company in writing, no change may be made that (i) decreases the Offer Price,
(ii) changes the form of consideration to be paid in the Offer, (iii) reduces
the maximum number of Shares to be purchased in the Offer, (iv) amends or adds
to the Offer Conditions, (v) except as provided in the next sentence, extends
the Offer or (vi) amends any other term of the Offer in any manner adverse to
the holders of the Shares. Notwithstanding the foregoing, Purchaser may, without
the consent of the Company, (A) extend the Offer, if at the then scheduled or
extended Expiration Date any of the Offer Conditions shall not be satisfied or
waived, until such time as such conditions are satisfied or waived, (B) extend
the Offer for any period required by any rule, regulation, interpretation or
position of the Securities and Exchange Commission (the "SEC") or the staff
thereof applicable to the Offer, (C) 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 (A) or (B) of
this sentence, and (D) 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 (A), (B) or (C) of this
sentence, if on such Expiration Date there shall not have been tendered at least
90% of the outstanding Shares. Subject to the terms and conditions of the Offer
and this Agreement, Purchaser shall, and Parent shall cause Purchaser to, accept
for payment, and pay for, all Shares validly tendered and not withdrawn pursuant
to the Offer that Purchaser becomes obligated to accept for payment, and pay
for, pursuant to the Offer as promptly as practicable after the expiration of
the Offer. The parties agree that the conditions set forth in Annex A are for
the sole benefit of Purchaser and may be asserted by Purchaser regardless of the
circumstances giving rise to any such condition (including any action or
inaction by Purchaser or Parent) or may be waived by Purchaser, in whole or in
part, at any time and from time to time, in its sole discretion. The failure by
Purchaser at any time to exercise any of the foregoing rights shall not be
deemed a waiver of any such right, the waiver of any such right with respect to
particular facts and circumstances shall not be deemed a waiver with respect to
other facts or circumstances, and each such right shall be deemed an ongoing
right that may be asserted at any time and from time to time. Any determination
(which will be made in good faith) by Purchaser with respect to any of the
foregoing conditions (including, without limitation, the satisfaction of such
conditions) shall be final and binding on all parties. The Offer Price will be
paid net to the seller in cash, less any required withholding taxes, on the
terms and subject to the conditions of the Offer.

     (b) On the date of commencement of the Offer, Parent and Purchaser shall
file with the SEC a Tender Offer Statement on Schedule 14D-1 (the "SCHEDULE
14D-1") with respect to the Offer, which shall contain an offer to purchase and
a related letter of transmittal and summary advertisement (such Schedule 14D-1
and the documents included therein pursuant to which the Offer will be made,
together with any supplements or amendments thereto, the "OFFER DOCUMENTS").
Parent and Purchaser agree that the Offer Documents shall comply as to form in
all material respects with the Securities Exchange Act of 1934, as amended (the
"EXCHANGE ACT"), and the rules and regulations promulgated thereunder. The Offer
Documents, 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 or warranty is made by
Parent or Purchaser with respect to information supplied by the Company or any
of its stockholders specifically for inclusion or incorporation by reference in
the Offer Documents. Each of Parent, Purchaser and the Company agrees promptly
to correct any information provided by it for use in the Offer Documents if and
to the extent that such information shall have become false or misleading in any
material respect, and Parent and Purchaser further agree to take all steps
necessary to cause the Schedule 14D-1 as so corrected to be filed with the SEC
and the other Offer Documents as so corrected to be disseminated to the
Company's stockholders, in each case as and to the extent required by applicable
federal securities laws. The Company and its counsel shall be given an
opportunity to review and comment upon the Offer Documents prior to their filing
with the SEC or dissemination to the stockholders of the Company. Parent and
Purchaser agree to provide the Company and its counsel any comments Parent,

                                        2
<PAGE>   6

Purchaser or their counsel may receive from the SEC or its staff with respect to
the Offer Documents promptly after the receipt of such comments.

     SECTION 1.2  Company Actions. (a) The Company hereby represents and
warrants that the Board of Directors of the Company (the "BOARD OF DIRECTORS"),
at a meeting duly called and held at which all directors were present, duly and
unanimously: (i) determined that the Offer and the Merger, taken together, are
fair to, and in the best interests of, the holders of the Shares; (ii) approved
the Offer and the Merger; (iii) approved the Stockholder Agreements, Purchaser
entering into such Stockholder Agreements, the acquisition of shares by
Purchaser pursuant thereto and the other transactions contemplated thereby; (iv)
resolved to recommend that the stockholders of the Company accept the Offer,
tender their Shares pursuant to the Offer and approve the Merger, if such
approval is required; and (v) approved and adopted this Agreement and approved
the acquisition of Shares by Purchaser pursuant to the Offer and the other
transactions contemplated by this Agreement. The Company also represents and
warrants that its Board of Directors has received the written opinion of Simmons
& Company International (the "FINANCIAL ADVISOR") that, as of the date hereof,
the proposed consideration to be offered to the Company's stockholders pursuant
to the Offer and the Merger is fair to the Company's stockholders from a
financial point of view. The Company further represents and warrants that it has
been authorized by the Financial Advisor to permit, subject to prior review and
consent by the Financial Advisor (such consent not to be unreasonably withheld),
the inclusion of such fairness opinion (or a reference thereto) in the Offer
Documents and in the Schedule 14D-9 referred to below. The Company hereby
consents to the inclusion in the Offer Documents of the recommendations of the
Company's Board of Directors described in this Section 1.2(a) (subject to the
right of the Board of Directors to modify or withdraw such recommendation in
accordance with Section 5.3(b)).

     (b) The Company shall file with the SEC and shall mail to its stockholders
a Solicitation/Recommendation Statement on Schedule 14D-9 (together with all
schedules, amendments and supplements, the "SCHEDULE 14D-9") containing the
recommendations of the Board of Directors of the Company and the opinion of the
Financial Advisor referred to in Section 1.2(a). The Schedule 14D-9 shall comply
as to form in all material respects with the requirements of the Exchange Act
and the rules and regulations promulgated thereunder 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 or warranty is made by
the Company with respect to information supplied by Parent or Purchaser
specifically for inclusion in the Schedule 14D-9. Each of the Company, Parent
and Purchaser agrees promptly to correct any information provided by it for use
in the Schedule 14D-9 if and to the extent that such information shall have
become false or misleading in any material respect, and the Company further
agrees to take all steps necessary to amend or supplement the Schedule 14D-9 and
to cause the Schedule 14D-9 as so amended or supplemented to be filed with the
SEC and disseminated to the Company's stockholders, in each case as and to the
extent required by applicable federal securities laws. Parent and its counsel
shall be given an opportunity to review and comment upon the Schedule 14D-9
prior to its filing with the SEC or dissemination to stockholders of the
Company. The Company agrees to provide Parent and its counsel any comments the
Company or its counsel may receive from the SEC or its staff with respect to the
Schedule 14D-9 promptly after the receipt of such comments.

     (c) In connection with the Offer and the Merger, the Company shall cause
its transfer agent to furnish Purchaser promptly with mailing labels containing
the names and addresses of the record holders of Shares as of a recent date and
of those persons becoming record holders subsequent to such date, together with
copies of all lists of stockholders, security position listings and computer
files and all other information in the Company's possession or control regarding
the beneficial owners of Shares, and shall furnish to Purchaser such information
and assistance (including updated lists of stockholders, security position
listings and computer files) as Parent may reasonably request in communicating
the Offer to the Company's stockholders. Subject to the requirements of
applicable law, and except for such steps as are necessary to disseminate the
Offer Documents and any other documents necessary to consummate the Merger,
Parent and Purchaser and their agents shall hold in confidence the information
contained in any such labels, listings and files, and will use such information
only in connection with the Offer and the Merger.

     SECTION 1.3  Board of Directors. (a) Effective upon the payment by
Purchaser for Shares pursuant to the Offer, Purchaser shall be entitled to
designate that number of directors of the Company, rounded up to the next whole
number, that equals the product of (x) the total number of directors on the
Board of Directors (giving effect to the election or appointment of any
additional directors pursuant to this Section 1.3) and (y) the percentage that
the number of Shares owned by Parent and Purchaser (including Shares accepted
for payment) bears to the total number of Shares then outstanding. The Company
shall take all action necessary to cause the designees of Purchaser to be
elected to or appointed by the Board of Directors, including, without
limitation, increasing the number of directors, amending its bylaws, or using
its best efforts to obtain resignations of incumbent directors. Upon written
request by Purchaser, the Company shall use its best efforts to cause the
designees of Purchaser to constitute the same percentage of representation as is
on the Board of Directors after giving effect to this Section 1.3 on (i) each
committee of the Board of Directors; (ii) the board of directors of each
Subsidiary (as defined in Section 9.1) of the Company; and (iii) each committee
of each such board. The provisions of this Section 1.3 are in addition to and
shall not limit any rights that Purchaser, Parent or any of their affiliates may
have as a holder or beneficial owner of Shares as a matter of law with respect
to the election of directors or otherwise.

     (b) The Company shall promptly take all actions required pursuant to
Section 14(f) of the Exchange Act and Rule 14f-1 promulgated thereunder in order
to fulfill its obligations under Section 1.3(a), including mailing to
stockholders together with the Schedule 14D-9 the information required by such
Section 14(f) and Rule 14f-1 as is necessary to enable Parent's designees to be
elected to the Company's Board of Directors (the "14F-1 INFORMATION STATEMENT").
Parent or Purchaser shall supply the Company and be solely responsible for any
information with respect to either of them and their nominees, officers,
directors and affiliates required by such Section 14(f) and Rule 14f-1. The
14f-1 Information Statement, 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 or warranty is made by the Company
with respect to information supplied by Parent or Purchaser specifically for
inclusion in the 14f-1 Information Statement.

     (c) In the event that Purchaser's designees are elected to the Company's
Board of Directors, until the Effective Time (as defined below), the Company's
Board of Directors shall have at least two directors who are directors on the
date hereof (the "INDEPENDENT DIRECTORS"), provided that, in such event, if the
number of Independent Directors shall be reduced below two for any reason
whatsoever, any remaining Independent Directors (or Independent Director, if
there be only one remaining) shall be entitled to designate persons to fill such
vacancies who shall be deemed to be Independent Directors for purposes of this
Agreement or, if no Independent Director then remains, the other directors shall
designate two persons to fill such vacancies who shall not be stockholders,
affiliates or associates of Parent or Purchaser and such persons shall be deemed
to be Independent Directors for purposes of this Agreement. Notwithstanding
anything in this Agreement to the contrary, in the event that Purchaser's
designees are elected to the Company's Board, after the acceptance for payment
of Shares pursuant to the Offer and prior to the Effective Time, the affirmative
vote of a majority of the Independent Directors shall be required to (a) amend
or terminate this Agreement by the Company or (b) exercise or waive any of the
Company's rights, benefits or remedies hereunder.

                                  ARTICLE II.

                                   THE MERGER

     SECTION 2.1  The Merger. Subject to the last two sentences of this Section
2.1, upon the terms and subject to the conditions set forth in this Agreement,
and in accordance with the General Corporation Law of the State of Delaware (the
"DGCL"), Purchaser shall be merged with and into the Company at the Effective
Time. Following the Effective Time, the separate corporate existence of
Purchaser shall cease and the Company shall continue as the surviving
corporation (the "SURVIVING CORPORATION") and shall succeed to and assume all
the rights and obligations of Purchaser in accordance with the DGCL. At the
election of Parent, to the extent that any such action would not cause a failure
of a condition to the Offer or the Merger, (i) any direct or indirect
wholly-owned subsidiary of Parent may be substituted for and assume all of the
rights and obligations of Purchaser as a constituent corporation in the Merger
or (ii) the Company may be merged with and into Purchaser with Purchaser
continuing as the Surviving Corporation with the effects set forth above and in
Section 2.4. In either such event, the parties agree to execute an appropriate
amendment to this Agreement in order to reflect the foregoing.

     SECTION 2.2  Closing. The closing of the Merger will take place at 10:00
a.m. (Dallas, Texas time) on a date to be specified by Parent or Purchaser,
which shall be no later than the second Business Day after satisfaction or
waiver of the conditions set forth in Article VI (the "CLOSING DATE"), at the
offices of Akin, Gump, Strauss, Hauer & Feld, L.L.P., 1700 Pacific Avenue, Suite
4100, Dallas, Texas 75201, unless another date, time or place is agreed to in
writing by the parties hereto.

     SECTION 2.3  Effective Time. Subject to the provisions of this Agreement,
as soon as practicable on or after the Closing Date, the parties shall file a
certificate of merger or other appropriate documents (in any such case, the
"CERTIFICATE OF MERGER") executed in accordance with the relevant provisions of
the DGCL and shall make all other filings or recordings required under the DGCL.
The Merger shall become effective at such time as the Certificate of Merger is
duly filed with the Delaware Secretary of State, or at such other time as
Purchaser and the Company shall agree should be specified in the Certificate of
Merger (the time the Merger becomes effective being hereinafter referred to as
the "EFFECTIVE TIME").

     SECTION 2.4  Effects of the Merger. The Merger shall have the effects set
forth in Section 259 of the DGCL.

     SECTION 2.5  Certificate of Incorporation and Bylaws. (a) The Certificate
of Incorporation of the Company (the "CERTIFICATE OF INCORPORATION") as in
effect immediately prior to the Effective Time shall be the certificate of
incorporation of the Surviving Corporation, until thereafter changed or amended,
as provided therein or by applicable law.

     (b) The Bylaws of the Company as in effect immediately prior to the
Effective Time, shall be the Bylaws of the Surviving Corporation, until
thereafter changed or amended, as provided therein or by applicable law.

     SECTION 2.6  Directors. The directors of Purchaser immediately prior to the
Effective Time shall be the directors of the Surviving Corporation, until the
earlier of their resignation or removal or their respective successors are duly
elected and qualified, as the case may be.

     SECTION 2.7  Officers. The officers of Purchaser immediately prior to the
Effective Time shall be the officers of the Surviving Corporation, until the
earlier of their resignation or removal or their respective successors are duly
elected and qualified, as the case may be.

     SECTION 2.8  Effect on Capital Stock. As of the Effective Time, by virtue
of the Merger and without any action on the part of the holder of any Shares or
any shares of capital stock of Purchaser:

     (a) Capital Stock of Purchaser. Each issued and outstanding share of
capital stock of Purchaser shall be converted into and become one fully paid and
nonassessable share of common stock of the Surviving Corporation.

     (b) Cancellation of Treasury Stock and Parent-Owned Stock. Each Share that
is owned by the Company or by any wholly-owned Subsidiary of the Company and
each Share that is owned by Parent,
                                        5
<PAGE>   9

Purchaser or any other wholly-owned Subsidiary of Parent shall automatically be
canceled and retired and shall cease to exist, and no consideration shall be
delivered in exchange therefor.

     (c) Conversion of Shares. Subject to Section 2.8(d), each issued and
outstanding Share (other than Shares to be canceled in accordance with Section
2.8(b)) shall be converted into the right to receive from the Surviving
Corporation in cash, without interest, the Offer Price (the "MERGER
CONSIDERATION"). As of the Effective Time, all such Shares shall no longer be
outstanding and shall be automatically canceled 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, without interest.

     (d) Shares of Dissenting Stockholders. Notwithstanding anything in this
Agreement to the contrary, any issued and outstanding Shares held by a person (a
"DISSENTING STOCKHOLDER") who objects to the Merger and complies with all the
provisions of DGCL concerning the right of holders of Shares to dissent from the
Merger and require appraisal of their Shares ("DISSENTING SHARES") shall not be
converted as described in Section 2.8(c), but shall be converted into the right
to receive such consideration as may be determined to be due to such Dissenting
Stockholder pursuant to the DGCL. If, after the Effective Time, such Dissenting
Stockholder withdraws its demand for appraisal or fails to perfect or otherwise
loses its right to appraisal, in any case pursuant to the DGCL, such Dissenting
Stockholder's Shares shall be deemed to be converted as of the Effective Time
into the right to receive the Merger Consideration. 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.

     SECTION 2.9  Exchange of Certificates.

     (a) Paying Agent. Prior to the Effective Time, Parent shall designate a
bank or trust company to act as agent for the holders of the Shares in
connection with the Merger (the "PAYING AGENT") to receive in trust the funds to
which holders of the Shares shall become entitled pursuant to Section 2.8(c).
From time to time, Parent shall make available, or cause the Surviving
Corporation to make available, to the Paying Agent cash in amounts and at times
necessary for the prompt payment of the Merger Consideration upon surrender of
certificates representing Shares as provided herein. All interest earned on such
funds shall be paid to Parent.

     (b) Exchange Procedure. As soon as reasonably practicable after the
Effective Time, the Paying Agent shall mail to each holder of record of a
certificate or certificates that immediately prior to the Effective Time
represented Shares (the "CERTIFICATES"), (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 a form and have such other provisions as Parent may
reasonably specify) and (ii) instructions for use in effecting the surrender of
the Certificates in exchange for the Merger Consideration. Upon surrender of a
Certificate for cancellation to the Paying Agent or to such other agent or
agents as may be appointed by Parent, together with such letter of transmittal,
duly executed, and such other documents as may reasonably be required by the
Paying Agent, the holder of such Certificate shall be entitled to receive in
exchange therefor the amount of cash into which the Shares theretofore
represented by such Certificate shall have been converted pursuant to Section
2.8, and the Certificate so surrendered shall forthwith be canceled. In the
event of a transfer of ownership of Shares that is not registered in the
transfer records of the Company, payment may be made to a person other than the
person in whose name the Certificate so surrendered is registered, if such
Certificate shall be properly endorsed or otherwise be in proper form for
transfer and the person requesting such payment shall pay any transfer or other
taxes required by reason of the payment to a person other than the registered
holder of such Certificate or establish to the satisfaction of the Surviving
Corporation that such tax has been paid or is not applicable. Until surrendered
as contemplated by this Section 2.9, each Certificate shall be deemed at any
time after the Effective Time to represent only the right to receive upon such
surrender the amount of cash, without interest, into which the Shares
theretofore represented by such Certificate shall have been converted pursuant
to Section 2.8. No interest will be paid or will accrue on the cash payable upon
the surrender of any Certificate.

                                        6
<PAGE>   10

     (c) No Further Ownership Rights in Shares; Transfer Books. All cash paid
upon the surrender of Certificates in accordance with the terms of this Article
II shall be deemed to have been paid in full satisfaction of all rights
pertaining to the Shares theretofore represented by such Certificates. At the
Effective Time, the stock transfer books of the Company shall be closed, and
there shall be no further registration of transfers on the stock transfer books
of the Surviving Corporation of the Shares that were outstanding immediately
prior to the Effective Time. If, after the Effective Time, Certificates are
presented to the Surviving Corporation or the Paying Agent for any reason, they
shall be canceled and exchanged as provided in this Article II.

     (d) Termination of Fund; No Liability. At any time following six months
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,
none of Parent, Purchaser, the Company or the Paying Agent shall be liable to
any person in respect of any cash delivered to a public official pursuant to any
applicable abandoned property, escheat or similar law. If any Certificates shall
not have been surrendered immediately prior to such date on which any payment
pursuant to this Article II would otherwise escheat to or become the property of
any Governmental Entity (as defined in Section 3.4), the cash payment in respect
of such Certificate shall, to the extent permitted by applicable law, become the
property of the Surviving Corporation, free and clear of all claims or interests
of any person previously entitled thereto.

     (e) Lost, Stolen or Destroyed Certificates. In the event any Certificates
evidencing Shares shall have been lost, stolen or destroyed, the Paying Agent
shall pay to such holder the Merger Consideration required pursuant to Section
2.8, in exchange for such lost, stolen or destroyed Certificates, upon the
making of an affidavit of that fact by the holder thereof with such assurances
as the Paying Agent, in its discretion and as a condition precedent to the
payment of the Merger Consideration, may reasonably require of the holder of
such lost, stolen or destroyed Certificates.

     (f) Withholding Taxes. Parent and Purchaser shall be entitled to deduct and
withhold, or cause the Paying Agent to deduct and withhold, from the
consideration otherwise payable to a holder of Shares pursuant to the Offer or
the Merger any stock transfer taxes and such amounts as are required under the
Internal Revenue Code of 1986, as amended (the "CODE"), or any applicable
provisions of state, local or foreign tax law. To the extent that amounts are so
withheld, such withheld amounts shall be treated for all purposes of this
Agreement as having been paid to the holder of the Shares in respect of which
such deduction and withholding were made.

     SECTION 2.10  Stock Options.

     (a) The Company shall (i) use its best efforts to cause each holder of an
outstanding employee or director stock option to purchase Shares (the "STOCK
OPTIONS") granted under the 1997 Incentive Plan of the Company, as amended (the
"STOCK PLAN"), whether or not then exercisable or vested, to enter into an Award
Termination Agreement in the form furnished to Purchaser (individually referred
to as an "AWARD TERMINATION AGREEMENT" and collectively as "AWARD TERMINATION
AGREEMENTS"), under which each such Stock Option shall be canceled effective as
of the Effective Time and (ii) in consideration of such cancellation, and except
to the extent that Parent or Purchaser and the holder of any such Stock Option
otherwise agree, cause the Company (or, at Parent's option, Purchaser) to pay to
each holder of a Stock Option, within five business days after the Effective
Time, an amount in respect thereof equal to the product of (A) the excess, if
any, of the Offer Price over the exercise price of such Stock Option and (B) the
number of Shares previously subject to such Stock Option immediately prior to
its cancellation (such payment to be net of withholding taxes). The Company
shall take all actions necessary to cause the Company's employees and directors
to consent, to the extent required, to the transactions contemplated by this
Section 2.10(a) no later than immediately prior to the time Purchaser accepts
Shares for payment pursuant to the Offer; provided, however, that the failure to
obtain the consent of the holders of Stock Options for not more than an
aggregate

                                        7
<PAGE>   11

of 200,000 shares (such Stock Options for which consent has not been so obtained
being herein referred to as the "CONVERTED OPTIONS") shall not be deemed to be a
breach of this Section 2.10. Notwithstanding the foregoing, at the Effective
Time, each Converted Option, whether vested or unvested, shall be deemed to
constitute an option (a "NEW PARENT OPTION") to acquire, on the same terms and
conditions as were applicable under such Converted Options, the number of shares
of common stock of Parent ("PARENT COMMON STOCK") (rounded down to the nearest
whole number) equal to the product of (A) the number of Shares of Common Stock
issuable upon exercise of such Converted Option and (B) the Offer Price divided
by the average closing sale price of the Parent Common Stock on the New York
Stock Exchange Composite Tape (as reported by The Wall Street Journal
(Southwestern Edition)) for the ten consecutive trading days immediately prior
to and including the date preceding the Effective Time (such product being the
"OPTION EXCHANGE RATIO"), at an exercise price (rounded to the nearest whole
cent) equal to (X) the exercise price per share at which Common Stock shall have
been purchasable under the Stock Plan immediately prior to the Merger divided by
(Y) the Option Exchange Ratio.

     (b) Except as may be otherwise agreed to by Parent or Purchaser and the
Company, as of the Effective Time, (i) the Company's Stock Plan shall terminate,
(ii) the provisions in any other plan, program or arrangement providing for the
issuance or grant of any other interest in respect of the capital stock of the
Company or any of its Subsidiaries shall be deleted and (iii) no holder of Stock
Options or any participant in the Stock Plan or any other plans, programs or
arrangements shall have any rights thereunder to acquire any equity securities
of the Company, the Surviving Corporation or any subsidiary thereof. The Company
shall take all actions necessary to cause the Company's employees and directors
to consent, to the extent required, to the transactions contemplated by this
Section 2.10(b) no later than immediately prior to the time Purchaser accepts
Shares for payment pursuant to the Offer.

                                  ARTICLE III.

                 REPRESENTATIONS AND WARRANTIES OF THE COMPANY

each jurisdiction in which the character of the properties owned or leased by it
or the nature of its business makes such qualification necessary, except in
jurisdictions, if any, where the failure to be so qualified would not,
individually or in the aggregate, result in a Material Adverse Effect (as
defined in Section 9.1) on the Company. The Company has all requisite corporate
power and authority to own, use or lease its properties and to carry on its
business as it is now being conducted. The Company has made available to Parent
a complete and correct copy of its Certificate of Incorporation and Bylaws, each

and the jurisdictions in which each such Subsidiary is qualified or holds
licenses to do business as a foreign corporation or other organization as of the

existing and in good standing under the laws of its jurisdiction of
organization, is duly qualified to do business as a foreign entity and is in
good standing in the jurisdictions set forth in Section 3.1(b) of the Disclosure
Letter, which includes each jurisdiction in which the character of such
Subsidiary's properties owned or leased by it or the nature of its business
makes such qualification necessary, except in jurisdictions, if any, where the
failure to be so qualified would not, individually or in the aggregate, result
in a Material Adverse Effect on the Company. Each of the Company's

                                        8

Subsidiary of the Company is in default in any material respect in the
performance, observation or fulfillment of any provision of its certificate of
incorporation or bylaws (or similar organizational documents). Other than its
Subsidiaries, the Company does not beneficially own or control, directly or
indirectly, any class of equity or similar securities of any corporation or
other organization, whether incorporated or unincorporated.

capital stock of the Company.

     (b) Set forth in Section 3.2(b) of the Disclosure Letter is a complete and
accurate list showing, as of the date hereof, as to each Subsidiary of the
Company, the number of shares of each class of capital stock, or other equity

hypothecate or otherwise dispose of such capital stock or other equity
interests). There are no securities, options, warrants, calls, rights,
commitments, agreements, arrangements or undertakings of any kind to which the
Company or any of its Subsidiaries is a party, or by which the Company or any of

     SECTION 3.3  Authority. The Company has the requisite corporate power and
authority to enter into this Agreement and, subject to, if required by law,
approval of the Merger by an affirmative vote of the holders of a majority of
the Shares (the "COMPANY STOCKHOLDER APPROVAL"), to consummate the transactions
contemplated by this Agreement. The execution and delivery of this Agreement by
the Company and the consummation by the Company of the transactions contemplated
by this Agreement have been duly and validly authorized by all necessary
corporate action on the part of the Company, subject, in the case of the Merger,
to the Company Stockholder Approval if such approval is required by law. This
Agreement has been duly and validly executed and delivered by the Company and
constitutes a valid and binding obligation of the Company, enforceable against
the Company in accordance with its terms.

     SECTION 3.4  Consents and Approvals; No Violations. The execution and
delivery of this Agreement by the Company do not, and the consummation by the
Company of the transactions contemplated by this Agreement and compliance with
the provisions of this Agreement will not, conflict with, or result in any
violation of, or default (with or without notice or lapse of time, or both)
under, or give rise to a right of termination, cancellation or acceleration of
any obligation or to loss of a material benefit under, or result in the creation
of any Lien in or upon any of the properties or assets of the Company or any of
its Subsidiaries under any provision of (i) the Certificate of Incorporation or
Bylaws of the Company or the comparable organizational documents of any
Subsidiary of the Company, (ii) any loan or credit agreement, note, bond,
mortgage, indenture, lease or other agreement, instrument, permit, concession,

been timely filed or requests for extensions to file such returns or reports
have been timely filed and granted and have not expired, and all returns filed
are complete and accurate except to the extent any failure to file or any
inaccuracies in filed returns would not, individually or in the aggregate, have
a Material Adverse Effect on the Company. All Taxes due and owing by the
Company, any Subsidiary of the Company or any Company Group have been paid, or
adequately reserved for, except to the extent any failure to pay or reserve
would not, individually or in the aggregate, have a Material Adverse Effect on
the Company. There is no audit examination, deficiency, refund litigation,
proposed adjustment or matter in controversy with respect to any Taxes due and
owing by the Company, any Subsidiary of the Company or any Company Group nor has
the Company or any Subsidiary filed any waiver of the statute of limitations
applicable to the assessment or collection of any Tax, in each case, which
would, individually or in the aggregate, have a Material Adverse Effect on the
Company. All assessments for Taxes due and owing by the Company, any Subsidiary
of the Company or any Company Group with respect to completed and settled

Subsidiary is a party to any tax indemnity agreement, tax sharing agreement or
other agreement under which the Company or any Subsidiary could become liable to
another person as a result of the imposition of a Tax upon any person, or the
assessment or collection of a Tax, except for such agreements as would not in

federal income Taxes have not expired, and (ii) with respect to federal income
Taxes, those years for which examinations have been completed, those years for

regulations relating to the withholding of Taxes, except to the extent any such
failure to comply would not, individually or in the aggregate, have a Material
Adverse Effect on the Company.

<PAGE>   20

Current SEC Reports (other than properties and assets disposed of in the
ordinary course of business since the date of such balance sheet), and all such
properties and assets are free and clear of any Liens, except as described in
the Current SEC Reports and the financial statements included therein or in
Section 3.17 of the Disclosure Letter and other than Liens for current taxes not
yet due and other Liens or title imperfections that do not have, and are not
reasonably likely to have, a Material Adverse Effect on the Company.

     SECTION 3.18  Information in Proxy Statement. The Proxy Statement, if any
(or any amendment thereof or supplement thereto), including any information
incorporated by reference therein, will, at the date mailed to the stockholders
of the Company and at the time of the meeting of the stockholders of the
Company, not contain any untrue statement of a material fact or omit to state
any material fact required to be stated therein or necessary in order to make
the statements therein, in light of the circumstances under which they are made,
not misleading, except that no representation is made by the Company with
respect to statements made therein based on information supplied by Parent or
Purchaser for inclusion in the Proxy Statement. The Proxy Statement will comply
in all material respects with the provisions of the Exchange Act and the rules
and regulations thereunder.

     SECTION 3.19  Takeover Restrictions; Rights Agreement.

     (a) Other than Section 203 of the DGCL, no state takeover statute or
similar statute or regulation of any state or other jurisdiction applies, or to
the knowledge of the Company purports to apply, to this Agreement, the
Stockholder Agreements or any of the transactions contemplated herein or
therein, including the Merger. Assuming Parent and its "associates" and
"affiliates" (as defined in Section 203 of the DGCL) collectively beneficially
own, and have beneficially owned at all times during the three year period prior
to the date hereof, less than fifteen percent (15%) of the Common Stock
outstanding, the action of the Board of Directors of the Company in approving
the Offer (including the purchase of Shares pursuant to the Offer), the Merger,
this Agreement, the Stockholder Agreements and the transactions contemplated by
this Agreement and the Stockholder Agreements is sufficient to render
inapplicable to the Offer, the Merger, this Agreement and the Stockholder
Agreements the provisions of Section 203 of the DGCL.

     (b) No provision of the Certificate of Incorporation or Bylaws of the
Company or comparable organizational documents of any of the Company's
Subsidiaries would, directly or indirectly, restrict or impair the ability of
Purchaser or its affiliates to vote, or otherwise to exercise the rights of a
shareholder with respect to, securities of the Company or any Subsidiary that
may be acquired or controlled by Purchaser or its affiliates pursuant to this
Agreement or the Stockholder Agreements or permit any shareholder to acquire
securities of the Company on a basis not available to Purchaser in the event
that Purchaser were to acquire securities of the Company.

     (c) The Company has made available to Parent a complete and correct copy of
the Rights Agreement, including all amendments and exhibits thereto. The Company
and the Board of Directors of the Company have taken, and will maintain in
effect during the term of this Agreement, all action necessary to ensure that
(x) none of Parent, Purchaser or any of their Affiliates or Associates (as such
terms are defined in the Rights Agreement) shall be or become an "Acquiring
Person", and no Stock Acquisition Date, Distribution Date, Flip-in Event or
Flip-Over Event (as such terms are defined in the Rights Agreement) shall occur,
as a result of (i) the execution, delivery or performance of this Agreement (or
any amendments hereto) or the consummation of the transactions contemplated
hereby, including, without limitation, the Offer and the Merger, (ii) the
execution, delivery or performance of the Stockholder Agreements or any
amendments thereto, or the consummation of the transactions contemplated
thereby, (iii) the announcement, making or commencement of the Offer or the
announcement of this Agreement or the Stockholder Agreements, (iv) the
acquisition of Beneficial Ownership (as such term is defined in the Rights
Agreement) of Shares or Rights pursuant to, or in connection with, this
Agreement, the Stockholder Agreements or otherwise as a result of any of the
transactions contemplated by this Agreement or the Stockholder Agreements,
including, without limitation, the Offer and the Merger; and (y) the Rights will
expire pursuant to the terms of the Rights Agreement immediately prior to the
Effective Time.

     SECTION 3.20  Brokers. No broker, investment banker, financial advisor or
other person, other than the Financial Advisor, the fees and expenses of which
will be paid by the Company, is entitled to any broker's,
                                       17
<PAGE>   21

finder's, financial advisor's or other similar fee or commission in connection
with the transactions contemplated by this Agreement based upon arrangements
made by or on behalf of the Company. The Company has furnished to Parent true
and complete copies of all agreements under which any such fees or expenses are
payable and all indemnification and other agreements related to the engagement
of the persons to whom such fees are payable.

     SECTION 3.21  Agreements with Creditors and Other Claimants. Section
3.21(a) of the Disclosure Letter lists all of the agreements which the Company
has entered into with any creditor and claimant of the Company in contemplation
of this Agreement and the amount to be paid to such creditor and claimant
pursuant to such agreement. The Company has forwarded true and complete copies
of all of the agreements listed in Section 3.21(a) of the Disclosure Letter. All
of such agreements are valid, in full force and effect and enforceable by the
Company in accordance with their terms. Neither the Company nor any of its
subsidiaries is in violation of or in default under (nor does there exist any
condition which with the lapse of time or the giving of notice or both would
cause such a violation of or default under) any such agreement. Except in
connection with liabilities permitted by Sections 3.7 and 3.8 (including,
without limitation, the liabilities set forth in Sections 3.7 and 3.8 of the
Disclosure Letter), there are no creditors or claimants of the Company owed or
claiming more than $10,000 which have not entered into agreements with the
Company in contemplation of this Agreement fixing the amount to be paid to them
by the Company.

     SECTION 3.22  Payments Pursuant to Sections 5.10 and 5.11. The aggregate
amounts payable pursuant to Sections 5.10 and 5.11 of this Agreement do not
exceed $7,870,454, and $4,346,006, respectively.

     SECTION 3.23  Company Transaction Costs. The aggregate amount of all fees,
costs and expenses of the Company and its subsidiaries actually incurred in
connection with this Agreement and the consummation of the transactions
contemplated hereby, including, without limitation the Offer, the Merger, and
the agreements and actions contemplated in Article 5 hereof, including any
investment banking, accounting, advisory, brokers, finders, printers or legal
fees or fees paid to any Government Entity or other third party (but excluding
the costs set forth in Section 3.23 of the Disclosure Letter that are deemed not
to be transaction costs for purposes of this Section 3.23), do not, and will not
as of the Expiration Date, exceed $1,550,000.

                                  ARTICLE IV.

                         REPRESENTATIONS AND WARRANTIES
                            OF PARENT AND PURCHASER

     Each of Parent and Purchaser represents and warrants to the Company as

     SECTION 4.1  Organization and Qualification. Purchaser is a corporation
duly organized, validly existing and in good standing under the laws of the
State of Delaware. Parent is a corporation duly organized, validly existing and
in good standing under the laws of the State of New York. Each of Parent and
Purchaser is duly qualified to do business as a foreign corporation and is in
good standing in each jurisdiction in which the character of the properties
owned or leased by it or the nature of its business makes such qualification
necessary, except in jurisdictions, if any, where the failure to be so qualified
would not, individually or in the aggregate, result in a Material Adverse Effect
on Parent or Purchaser. Each of Parent and Purchaser has all requisite corporate
power and authority to own, use or lease its properties and to carry on its
business as it is now being conducted.

     SECTION 4.2  Authority. Each of Parent and Purchaser has the requisite
corporate power and authority to enter into this Agreement and to consummate the

action on the part of Parent and Purchaser. This Agreement has been duly and
validly executed and delivered by Parent and Purchaser and constitutes a valid
and binding obligation of each such party, enforceable against each such party
in accordance with its terms.

<PAGE>   22

     SECTION 4.3  Consents and Approvals; No Conflicts. The execution and
delivery of this Agreement by Parent and Purchaser do not, and the consummation
by Parent and Purchaser of the transactions contemplated by this Agreement and
compliance by Parent and Purchaser with the provisions of this Agreement will
not, conflict with, or result in any violation of, or default (with or without
notice or lapse of time, or both) under, or give rise to a right of termination,
cancellation or acceleration of any obligation or to loss of a material benefit
under, or result in the creation of any Lien in or upon any of the properties or
assets of Parent or Purchaser under any provision of (i) the certificate of
incorporation or bylaws of Parent or Purchaser, (ii) any loan or credit
agreement, note, bond, mortgage, indenture, lease or other agreement,
instrument, permit, concession, franchise or license applicable to Parent or
Purchaser or any of their respective properties or assets or (iii) subject to
the governmental filings and other matters referred to in the following
sentence, any (A) statute, law, ordinance, rule or regulation or (B) judgment,
order or decree applicable to Parent or Purchaser or any of their respective
properties or assets, other than, in the case of clauses (ii) and (iii), any
such conflicts, violations, defaults, rights or Liens that individually or in
the aggregate would not (x) have a Material Adverse Effect on Parent, (y) impair
in any material respect the ability of Parent or Purchaser to perform its
respective obligations under this Agreement or (z) prevent or materially delay
the consummation of any of the transactions contemplated by this Agreement. No
consent, approval, order or authorization of, or registration, declaration or
filing with, any Governmental Entity, is required by or with respect to Parent
or Purchaser in connection with the execution and delivery of this Agreement by
Parent or Purchaser or the consummation by Parent or Purchaser of the
transactions contemplated by this Agreement, except for (1) the filing of a
premerger notification and report form under the HSR Act, (2) the filing with
the SEC of the Offer Documents and such reports under Sections 13(a), 13(d) and
16(a) of the Exchange Act as may be required in connection with this Agreement
and the transactions contemplated by this Agreement, (3) the filing of the
Certificate of Merger with the Delaware Secretary of State and appropriate
documents with the relevant authorities of other states in which the Company is
qualified to do business and (4) such other consents, approvals, orders,
authorizations, registrations, declarations and filings the failure of which to
be obtained or made would not, individually or in the aggregate, have a Material
Adverse Effect on Parent or prevent or materially delay the consummation of the
transactions contemplated by this Agreement.

     SECTION 4.4  Interim Operations of Purchaser. Purchaser was formed solely
for the purpose of engaging in the transactions contemplated hereby, and has
engaged in no other business activities.

     SECTION 4.5  Brokers. No broker, investment banker, financial advisor or
other person is entitled to any broker's, finder's, financial advisor's or other

     SECTION 4.6  Financing. Parent has funds or commitments to provide funds in
an amount adequate to purchase the Shares pursuant to the Offer and to pay the
Merger Consideration. Parent will have, and shall provide Purchaser with, the
funds necessary to consummate the Offer and the Merger and the transactions
contemplated hereby in accordance with the terms hereof.

                                   ARTICLE V.

                                   COVENANTS

     SECTION 5.1  Interim Operations of the Company. Except as expressly
contemplated by this Agreement or as set forth in Section 5.1 of the Disclosure
Letter, from the date hereof until the time the directors of Purchaser have been
elected to, and shall constitute a majority of, the Board of Directors of the
Company pursuant to Section 1.3 hereof (the "INTERIM PERIOD"), the Company
shall, and shall cause its Subsidiaries to, carry on their respective businesses
in the ordinary course consistent with the manner as heretofore conducted and,
to the extent consistent therewith, use commercially reasonable efforts to (x)
preserve intact their current business organization, (y) keep available the
services of their current officers and employees and (z) preserve their
relationships with customers, suppliers, licensors, licensees, distributors and
others having business dealings with them. Without limiting the generality of
the foregoing, during the Interim Period, other than as set forth in Section 5.1
of the Disclosure Letter or as otherwise contemplated by this Agreement, the

Subsidiaries or any securities convertible into or exchangeable for shares of
capital stock of any class of the Company or of its Subsidiaries other than
Shares issued upon the exercise of Stock Options outstanding on the date hereof
in accordance with the Stock Plan as in effect on the date hereof; or (iv)
split, combine or reclassify the outstanding capital stock of the Company or of
any of its Subsidiaries or authorize the issuance of any other securities in

partnership, limited liability company, joint venture, association or other
business organization or division thereof;

     (d) sell, lease, license, transfer, mortgage or otherwise encumber or

Time, or that would impair the ability of the Company to consummate the Merger
in accordance with the terms hereof or delay such consummation;

     (l) make or rescind any Tax election or settle or compromise any Tax

Company or any of its Subsidiaries (other than agreements or arrangements
between the Company and wholly-owned Subsidiaries or between wholly-owned

case may be, than could be reasonably expected to have been obtained with an
unaffiliated third party on an arm's-length basis;

     (p) amend, terminate or waive any provisions of any of the agreements set
forth in Section 3.21(a) of the Disclosure Letter; or

     (q) enter into an agreement, contract, commitment or arrangement to do any

do any of the foregoing.

     SECTION 5.2  Access to Information, Confidentiality. From the date hereof
to the Effective Time, the Company shall, and shall cause its Subsidiaries,
officers, directors, employees, auditors and other agents to, afford the
officers, employees, auditors, counsel, financing sources and other agents of
Parent access at all reasonable times (i) to the Company's and its Subsidiaries'
officers, employees, agents, properties, offices, and other facilities and to
all books and records, and shall furnish such persons with all financial,
operating and other data and information as they may from time to time request
(including accountants' work papers) and (ii) the Company's and its
Subsidiaries' management information systems and other consultants. During such
period, the Company shall, and shall cause its Subsidiaries to, furnish promptly
to Parent a copy of each report, schedule, registration statement and other
document filed or received by it during such period pursuant to the requirements
of the federal or state securities laws or the federal, state, local or foreign
tax laws. Parent will, and will cause Purchaser to, hold any such information
which is non-public in confidence in accordance
                                       21
<PAGE>   25

with the provisions of a letter agreement dated June 30, 1999 between the
Company and Parent (the "CONFIDENTIALITY AGREEMENT").

     SECTION 5.3  No Solicitation. (a) The Company shall not, nor shall it
permit any of its Subsidiaries to, nor shall it authorize or permit any officer,
director or employee of the Company or any of its Subsidiaries or any investment
banker, financial advisor, attorney, accountant or other representative or agent
retained by the Company or any Subsidiary (collectively, the "COMPANY
REPRESENTATIVES") to, directly or indirectly, (i) solicit, initiate or knowingly
encourage the submission of any Acquisition Proposal (as defined below) or (ii)
participate in any discussions or negotiations regarding, or furnish to any
person any nonpublic information with respect to, or take any other action
designated or reasonably likely to facilitate any inquiries or the making of any
proposal that constitutes an Acquisition Proposal; provided, however, that the
Company may, in response to an unsolicited Acquisition Proposal received after
the date hereof, and subject to compliance with Section 5.3(c), participate in
discussions or negotiations with a third party making an Acquisition Proposal
(and may furnish information to such third party pursuant to a customary
confidentiality agreement on terms no less favorable to the Company than the
Confidentiality Agreement) if (x) the Board of Directors of the Company
reasonably determines that the Acquisition Proposal is a bona fide Superior
Proposal (as defined below) and (y) the Board of Directors determines (after
consultation with independent outside counsel) that failing to take such action
could reasonably be determined to constitute a breach of its fiduciary duties to
the Company's stockholders under applicable law. The Company shall immediately
cease and cause to be terminated any existing solicitation, initiation,
encouragement, activity, discussion or negotiation with any person conducted
heretofore by the Company or any Company Representative with respect to any
Acquisition Proposal existing on the date hereof. The Company agrees not to
release any third party from, or amend or waive any provision of, any standstill
agreement to which it is a party unless the Board of Directors of the Company
determines (after consultation with independent outside counsel) that failing to
take such action could reasonably be determined to constitute a breach of its
fiduciary duties to the Company's stockholders under applicable law. Without
limiting the foregoing, it is understood that any violation of the restrictions
set forth in this Section 5.3(a) by any Company Representative shall be deemed
to be a breach of this Section 5.3(a) by the Company. For purposes of this
Agreement, "ACQUISITION PROPOSAL" means any inquiry, proposal or offer from any
person relating to any direct or indirect acquisition or purchase of a
substantial amount of assets of the Company and its Subsidiaries, taken as a
whole (other than the purchase of the Company's products in the ordinary course
of business), or of over 10% of any class of equity securities of the Company or
any of its Subsidiaries or any tender offer or exchange offer that if
consummated would result in any person beneficially owning 10% or more of any
class of equity securities of the Company or any of its Subsidiaries or any
merger, consolidation, business combination, sale of substantially all assets,
recapitalization, liquidation, dissolution or similar transaction involving the
Company or any of its Subsidiaries, other than the transactions contemplated by
this Agreement, or any other transaction the consummation of which could
reasonably be expected to impede, interfere with, prevent or materially delay
the Offer or the Merger or which would reasonably be expected to dilute
materially the benefits to Parent of the transactions contemplated hereby.

     (b) Except as set forth in this Section 5.3, neither the Board of Directors
of the Company nor any committee thereof shall (i) withdraw or modify, or
propose to withdraw or modify, in a manner adverse to Parent, the approval or
recommendation by such Board of Directors or such committee of the Offer, the
Merger or this Agreement, (ii) approve or recommend, or propose publicly to
approve or recommend, any Acquisition Proposal or (iii) cause the Company to
enter into any letter of intent, agreement in principle, acquisition agreement
or other similar agreement (each, an "ACQUISITION AGREEMENT") related to any
Acquisition Proposal. Notwithstanding the foregoing, prior to the time of
acceptance for payment of Shares in the Offer, the Board of Directors of the
Company may (subject to the terms of this and the following sentence) withdraw
or modify its approval or recommendation of the Offer, this Agreement or the
Merger, approve or recommend a Superior Proposal, or enter into an agreement
with respect to a Superior Proposal, in each case at any time after the second
business day following Parent's receipt of written notice advising Parent that
the Board of Directors of the Company has received a Superior Proposal,
specifying the material terms and conditions of such Superior Proposal and
identifying the person making such Superior Proposal; provided, that the Board
of Directors of the Company shall have determined (and been advised in writing
by
                                       22
<PAGE>   26

independent outside counsel) that the failure to take such action could
reasonably be determined to cause the Board of Directors of the Company to
violate its fiduciary duties to the Company's stockholders under applicable law;
and provided further, that the Company shall not enter into an Acquisition
Agreement with respect to a Superior Proposal unless the Company shall have
furnished Parent with written notice not later than noon (New York time) two
days in advance of any date that it intends to enter into such agreement and
shall have caused its financial and legal advisors to negotiate with Parent to
make such adjustments in the terms and conditions of this Agreement as would
enable the Company to proceed with the transactions contemplated herein on such
adjusted terms. In addition, if the Company proposes to enter into an
Acquisition Agreement with respect to any Acquisition Proposal, it shall
concurrently with entering into such agreement pay, or cause to be paid, to
Parent the Termination Fee (as defined in Section 8.1). For purposes of this
Agreement, a "SUPERIOR PROPOSAL" means any bona fide Acquisition Proposal made
by a third party (i) that is on terms which the Board of Directors of the
Company determines in its good faith judgment (based on consultation with the
Company's financial advisor) to be more favorable to the Company's stockholders
than the Offer and the Merger and (ii) for which financing, to the extent
required, is then committed or which, in the good faith judgment of the Board of
Directors of the Company, is capable of being obtained by such third party.

     (c) In addition to the obligations of the Company set forth in paragraphs
(a) and (b) of this Section 5.3, the Company shall promptly advise Parent orally
and in writing of any request for nonpublic information or of any Acquisition
Proposal known to it, the material terms and conditions of such request or
Acquisition Proposal and the identity of the person making such request or
Acquisition Proposal. The Company will promptly inform Parent of any material
change in the details (including amendments or proposed amendments) of any such
request or Acquisition Proposal.

     SECTION 5.4  Stockholder Approval; Preparation of Proxy Statement. (a) If
the Company Stockholder Approval is required by law, the Company shall, as soon
as practicable following the expiration of the Offer and payment for the Shares,
duly call, give notice of, convene and hold a meeting of its stockholders (the
"STOCKHOLDERS MEETING") for the purpose of obtaining the Company Stockholder
Approval. The Company shall, through its Board of Directors, recommend to its
stockholders that the Company Stockholder Approval be given. Notwithstanding the
foregoing, if Purchaser or any subsidiary of Parent shall acquire at least 90%
of the outstanding Shares, the parties shall take all necessary and appropriate
action to cause the Merger to become effective as soon as practicable after the
expiration of the Offer without a Stockholders Meeting in accordance with
Section 253 of the DGCL.

     (b) If the Company Stockholder Approval is required by law, the Company
shall, as soon as practicable following the expiration of the Offer, prepare and
file a preliminary Proxy Statement with the SEC and shall use its best efforts
to respond to any comments of the SEC or its staff and to cause the Proxy
Statement to be mailed to the Company's stockholders as promptly as practicable
after responding to all such comments to the satisfaction of the staff. The
Company shall notify Parent promptly of the receipt of any comments from the SEC
or its staff and of any request by the SEC or its staff for amendments or
supplements to the Proxy Statement or for additional information and will supply
Parent with copies of all correspondence between the Company or any of its
representatives, on the one hand, and the SEC staff, on the other hand, with
respect to the Proxy Statement or the Merger. If at any time prior to the
Stockholders Meeting there shall occur any event that should be set forth in an
amendment or supplement to the Proxy Statement, the Company shall promptly
prepare and mail to its stockholders such an amendment or supplement. The
Company shall not mail any Proxy Statement, or any amendment or supplement
thereto, to which Parent reasonably objects.

     (c) Parent agrees to cause all Shares purchased pursuant to the Offer and
all other Shares owned by Parent or any Subsidiary of Parent to be voted in
favor of the Company Stockholder Approval.

     SECTION 5.5  Reasonable Efforts. Upon and subject to the terms and subject
to the conditions set forth in this Agreement, each of the parties agrees to use
all reasonable efforts to take, or cause to be taken, all actions, and to do, or
cause to be done, and to assist and cooperate with the other parties in doing,
all things necessary, proper or advisable to consummate and make effective, in
the most expeditious manner practicable, the Offer, the Merger and the other
transactions contemplated by this Agreement, including using reasonable

                                       23
<PAGE>   27

efforts to take the following actions: (i) the taking of all reasonable acts
necessary to cause the Offer Conditions to be satisfied, (ii) the obtaining of
all necessary actions or nonactions, waivers, consents and approvals from
Governmental Entities and the making of all necessary registrations and filings
(including filings with Governmental Entities, if any) and the taking of all
reasonable steps as may be necessary to avoid an action or proceeding by any
Governmental Entity, (iii) the obtaining of all necessary consents, approvals or
waivers from third parties, (iv) the defending of any lawsuits or other legal
proceedings, whether judicial or administrative, challenging this Agreement or

any additional instruments necessary to consummate the transactions contemplated
by, and to fully carry out the purposes of, this Agreement. Notwithstanding
anything to the contrary contained in this Agreement, in connection with any
filing or submission required or action to be taken by Parent, the Company or
any of their respective Subsidiaries to consummate the Offer, the Merger or the
other transactions contemplated by this Agreement, the Company shall not,
without Parent's prior written consent, commit to any divestiture of assets or
businesses of the Company or any of its Subsidiaries if such divested assets
and/or businesses are material to the assets or profitability of the Company and
its Subsidiaries taken as a whole; and neither Parent nor any of its
Subsidiaries shall be required to divest or hold separate or otherwise take or
commit to take any action that limits its freedom of action with respect to, or
its ability to retain, the Company and its Subsidiaries or any of the
businesses, product lines or assets of Parent or any of its Subsidiaries or that
would have a Material Adverse Effect on Parent. In connection with and without
limiting the foregoing, but subject to the terms and conditions hereof, the
Company and its Board of Directors shall, if any state takeover statute or
similar statute or regulation is or becomes applicable to the Offer, the Merger,
this Agreement or any other transactions contemplated by this Agreement, use all
reasonable efforts to ensure that the Offer, the Merger and the other
transactions contemplated by this Agreement may be consummated as promptly as
practicable on the terms contemplated by this Agreement and otherwise to
minimize the effect of such statute or regulation on the Offer, the Merger, this
Agreement and the other transactions contemplated by this Agreement.

     SECTION 5.6  Notification of Certain Matters. The Company shall give prompt
notice to Parent, and Parent shall give prompt notice to the Company, of (a) any
representation or warranty made by it contained in this Agreement that is
qualified as to materiality becoming untrue or inaccurate in any respect or any
such representation or warranty that it not so qualified becoming untrue or
inaccurate in any material respect, and (b) any failure by it to comply with or
satisfy any covenant, condition, or agreement to be complied with or satisfied
by it under this Agreement. No such notification shall affect the
representations, warranties, covenants or agreements of the parties or the
conditions to the obligations of the parties under this Agreement.

     SECTION 5.7  Public Announcements. The initial press releases with respect
to the execution of this Agreement shall be prepared by the parties in form and
substance acceptable to Parent and the Company. Thereafter, so long as this
Agreement is in effect, neither the Company, Parent nor any of their respective
affiliates shall issue or cause the publication of any press release or other
announcement with respect to the Merger, this Agreement or the other
transactions contemplated hereby without the prior consultation of the other
party, except as may be required by law or by any listing agreement with a
national securities exchange or trading market.

any successor to the 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 and expenses (including reasonable fees and disbursements of
counsel and judgments, fines, losses, claims, liabilities and amounts paid in
settlement (provided that any such settlement is effected with the written
consent of Parent or the Surviving Corporation, which consent will not be
unreasonably withheld)) arising out of actions or omissions occurring at or
prior to the Effective Time to the full extent permitted under Delaware law
(provided that such actions or omissions were in compliance with the standards
set forth under Delaware law, the Certificate of Incorporation and the Bylaws of
the Company), subject to the terms of the Certificate of Incorporation and the
Bylaws of the Company, all as in effect at the date hereof; provided that,
                                       24
<PAGE>   28

in the event any claim or claims are asserted or made within such six-year
period, all rights to indemnification in respect of any such claim or claims
shall continue until disposition of any and all such claims; provided, further,
that nothing herein shall impair any rights or obligations of any present or
former directors or officers of the Company.

     (b) Parent or the Surviving Corporation shall maintain the Company's
existing officers' and directors' liability insurance for a period of not less
than six years after the Effective Date; provided, that the Parent may
substitute therefor policies of substantially similar coverage and amounts
containing terms no less favorable to such former directors or officers;
provided, further, that in no event shall the Company be required to pay
aggregate premiums for insurance under this Section in excess of 200% of the

purpose.

Purchaser and the Board of Directors of the Company.

     (b) By either of the Board of Directors of the Company or the Board of
Directors of Parent or Purchaser:

     therein; provided, however, that the right to terminate this Agreement
     under this Section 7.1(b)(i) shall not be available to any party whose
     failure to fulfill any obligation under this Agreement has been the cause
     of, or resulted in, the failure of Purchaser to purchase Shares pursuant to
     the Offer on or prior to the date on which the Offer shall have expired; or

          (ii) 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 hereto shall use their best efforts to lift), which
     permanently restrains, enjoins or otherwise prohibits the acceptance for
     payment of, or payment for, Shares pursuant to the Offer or the Merger and

     non-appealable.

     provisions thereof, including the notice provisions therein, and that the
     Company makes simultaneous payment of the Termination Fee; or

          (iii) if Parent or Purchaser shall have breached in any material
     respect any of their respective representations, warranties, covenants or
     other agreements contained in this Agreement, which breach cannot be or has
     not been cured within 30 days after the giving of written notice to Parent
     or Purchaser, as applicable, except, in any case, for such breaches which
     are not reasonably likely to affect adversely Parent's or Purchaser's
     ability to complete the Offer or the Merger.

     (d) By the Board of Directors of Parent or Purchaser:

          (i) if, due to an occurrence that if occurring after the commencement

     shall have failed to commence the Offer on or prior to five business days

     of a condition set forth in paragraph (f) or (h) of Annex A hereto; or

          (iii) if either Parent or Purchaser is entitled to terminate the Offer

     Notwithstanding any other provision of the Offer, and in addition to (and
not in limitation of) Purchaser's rights to extend and amend the Offer at any
time in its sole discretion (subject to the provisions of the Merger Agreement),
Purchaser shall not be required to accept for payment or, subject to any

exclusive of Shares potentially issuable under (w) Warrants subject to
termination under the Third Amendment to Loan Agreement, (x) Stock Options which
are to be terminated under duly executed Award Termination Agreements, (y)
conversion rights under Convertible Notes subject to duly executed Note
Modification Agreements and (z) Obligations subject to termination under any of
the duly executed Subsidiary Acquisition Agreements, other than the New Collier

expired or been terminated prior to the expiration of the Offer, or (iii) at any
time on or after the date of the Merger Agreement and prior to the acceptance
for payment for Shares, any of the following events shall occur or shall be
determined by the Purchaser to have occurred:

     (a) there shall have been threatened or instituted by any Governmental
Entity any action or proceeding before any court or governmental, administrative
or regulatory authority or agency of competent jurisdiction, domestic or
foreign, (i) challenging or seeking to make illegal, materially delay or
otherwise directly or indirectly restrain or prohibit or make materially more
costly the making of the Offer, the acceptance for payment of, or payment for,
any Shares by Parent, Purchaser or any other affiliate of Parent, or the
consummation of any other transaction contemplated by the Merger Agreement, or
seeking to obtain material damages in connection with the Offer, the Merger or
any such other transaction; (ii) seeking to prohibit or limit materially the
ownership or operation by the Company, Parent or any of their Subsidiaries of
all or any material portion of the business or assets of the Company, Parent or
any of their Subsidiaries, or to compel the Company, Parent or any of their
Subsidiaries to dispose of or hold separate all or any portion of the business
or assets of the Company, Parent or any of their Subsidiaries, as a result of
the Offer, the Merger or any of the other transactions contemplated by the
Merger Agreement; (iii) seeking to impose or confirm limitations on the ability
of Parent, Purchaser or any other affiliate of Parent to exercise effectively
full rights of ownership of any Shares, including, without limitation, the right
to vote any Shares acquired by Purchaser pursuant to the Offer or otherwise on
all matters properly presented to the Company's stockholders, including, without
limitation, the approval and adoption of this Agreement and the Merger; (iv)
seeking to require divestiture by Parent, Purchaser or any other affiliate of
Parent of any Shares; or (v) which otherwise has a Material Adverse Effect on
the Company;

     (b) there shall be any statute, rule, regulation, judgment, order or
injunction enacted, entered, enforced, promulgated or deemed applicable to the
Offer or the Merger, or any other action shall be taken by any Governmental
Entity, other than the application to the Offer or the Merger of applicable
waiting periods under the HSR Act, that is reasonably likely to result, directly
or indirectly, in any of the consequences referred to in clauses (i) through (v)
of paragraph (a) above;

     (c) there shall have occurred (i) any general suspension of trading in, or
limitation on prices for, securities on any national securities exchange or in
the Nasdaq National Market System, (ii) a declaration of a banking moratorium or
any suspension of payments in respect of banks in the United States (whether or
not

                                       A-1
<PAGE>   38

mandatory), (iii) a commencement of a war, armed hostilities or other
international or national calamity directly or indirectly involving the United
States, (iv) any limitation (whether or not mandatory) by any United States
governmental authority on the extension of credit by banks or other financial
institutions, or (v) in the case of any of the foregoing existing at the time of
commencement of the Offer, a material acceleration or worsening thereof;

     (d) there shall have occurred any material adverse change (or any
development that, insofar as reasonably can be foreseen, is reasonably likely to
result in any material adverse change) in the consolidated financial condition,
businesses, results of operations or prospects of the Company and its
Subsidiaries, taken as a whole, other than any such change that is the result of
cancellation of a distributor agreement or similar agreement from an original
equipment manufacturer or other material supplier;

     (e) (i) the Board of Directors of the Company or any committee thereof
shall have withdrawn or modified in a manner adverse to Parent or Purchaser its
approval or recommendation of the Offer, the Merger or this Agreement or
resolved to do so, or shall have approved or recommended any Acquisition
Proposal, or (ii) the Company shall have entered into any Acquisition Agreement
with respect to any Superior Proposal in accordance with Section 5.3(b) of the
Merger Agreement;

     (f) any of the representations and warranties of the Company set forth in
the Merger Agreement that are qualified as to materiality shall not be true and
correct and any such representations and warranties that are not so qualified
shall not be true and correct in any material respect, in each case as of the
date of the Merger Agreement and as of the scheduled Expiration Date of the
Offer;

     (g) (i) any stockholder of the Company party to a Stockholder Agreement
shall have failed to perform in any material respect any material obligation or
to comply in any material respect with any material agreement or covenant of
such stockholder to be performed or complied with by such stockholder under such
Stockholder Agreement or (ii) either Chapter 11 Stockholder Agreement shall not
have been approved by the Delaware Bankruptcy Court for the District of Delaware
and a plan of reorganization shall not have been confirmed by the Delaware
Bankruptcy Court with respect to the Chapter 11 Stockholder party to such
Chapter 11 Stockholder Agreement;

     (h) the Company shall have failed to perform in any material respect any
material obligation or to comply in any material respect with any material
agreement or covenant of the Company to be performed or complied with by it
under the Merger Agreement; or

     (i) the Merger Agreement shall have been terminated in accordance with its
terms;

which, in the reasonable judgment of Parent or Purchaser, in any such case and
regardless of the circumstances (unless such condition is caused by the action
or inaction of Parent or Purchaser) giving rise to such condition, makes it
inadvisable to proceed with the Offer and/or with such acceptance for payment of
or payment for Shares.

<PAGE>   1

                             STOCKHOLDER AGREEMENT

     STOCKHOLDER AGREEMENT, dated as of November 18, 1999 (this "Agreement"),
among Forrest Acquisition Sub, Inc., a Delaware corporation ("Purchaser"), and
each of the persons listed on Schedule I hereto (each a "Stockholder" and
collectively, the "Stockholders").

                                   RECITALS:

     WHEREAS, concurrently, with the execution and delivery of this Agreement,
Purchaser, Flowserve Corporation, a New York corporation ("Parent"), and
Innovative Valve Technologies, Inc., a Delaware corporation (the "Company"), are
entering into an Agreement and Plan of Merger (the "Merger Agreement"), which
provides, among other things, for the acquisition of the Company by Parent by
means of a cash tender offer (the "Offer") by Purchaser for all outstanding
shares of Common Stock, par value $0.001 per share, of the Company (the "Common
Stock"), including the associated preferred share purchase rights (the "Rights,"
and together with the Common Stock, the "Shares") and for the subsequent merger
of Purchaser with and into the Company (the "Merger"), all on the terms and
subject to the conditions set forth in the Merger Agreement;

     WHEREAS, as an inducement and a condition to entering into the Merger
Agreement, Parent and Purchaser have required that the Stockholders agree, and
the Stockholders have agreed, to enter into this Agreement; and

     WHEREAS, the Board of Directors of the Company has approved this Agreement
and the transactions contemplated hereby prior to the date hereof;

     NOW THEREFORE, in consideration of the foregoing and the mutual covenants
and agreements set forth herein, the parties hereto agree as follows:

     1. Definitions. Terms used and not defined herein, but defined in the
Merger Agreement, shall have the respective meanings ascribed to them in the
Merger Agreement.

     2. Tender of Shares; Agreement to Sell.

     (a) In order to induce Parent and Purchaser to enter into the Merger
Agreement, each Stockholder hereby agrees to validly tender (or cause the record
owner of such shares to validly tender), and not to withdraw, pursuant to and in
accordance with the terms of the Offer, not later than the tenth business day
after commencement of the Offer, the number of shares set forth opposite such
Stockholder's name on Schedule I hereto (the "Existing Shares" and, together
with any Shares acquired by such Stockholder in any capacity after the date
hereof and prior to the termination of this Agreement by means of purchase,
dividend, distribution, exercise of options, warrants or other rights to acquire
Shares or in any other way, the "Stockholder Shares"), all of which are
beneficially owned by such Stockholder. If a Stockholder acquires beneficial
ownership of Shares after the date hereof and prior to termination of this
Agreement, such Stockholder shall tender such Shares on such tenth business day
or, if later, on the second business day after such acquisition.

     (b) Purchaser shall be entitled to deduct and withhold from the
consideration otherwise payable hereunder to each Stockholder such amounts as
are required to be withheld under the Internal Revenue Code of 1986, as amended
(the "Code"), or any applicable provision of state, local or foreign tax law, as
specified in the Offer Documents. To the extent that amounts are so withheld by
Purchaser, such withheld amounts shall be treated for all purposes of this
Agreement as having been paid to such Stockholder.

     (c) Each Stockholder hereby permits Parent and Purchaser to publish and
disclose in the Offer Documents and, if approval of the Company's stockholders
is required under applicable law, the Proxy Statement (including all documents
and schedules filed with the SEC) the Stockholder's identity and ownership of
the Stockholder Shares and the nature of the Stockholder's commitments,
arrangements and understandings under this Agreement.
<PAGE>   2

     3. Option.

     (a) In order to induce Parent and Purchaser to enter into the Merger
Agreement, each Stockholder hereby grants to Purchaser an irrevocable option
(the "Option") to purchase the Stockholder Shares at a price equal to $1.62 per
Share. The Option may be exercised in whole or in part at any time prior to the
termination of this Agreement and after (i) the occurrence of any event as a
result of which Parent is entitled to receive a Termination Fee under the Merger
Agreement or (ii) such time as such Stockholder shall have breached in any
material respect any of its agreements in Section 2(a), 4(a), 4(b) or 4(d).

     (b) If the Option becomes exercisable under Section 3(a), the Option shall
remain exercisable until the later of (i) the date that is 90 days after the
date the Option becomes exercisable and (ii) the date that is ten days after the
date that all waiting periods under the HSR Act required for the purchase of the
Stockholder Shares upon such exercise shall have expired or been terminated;
provided, that if at the expiration of such period there shall be in effect any
injunction or other order issued by any Governmental Entity prohibiting the
exercise of the Option, the exercise period shall be extended until ten days
after the date that no such injunction or order is in effect. In the event
Purchaser wishes to exercise the Option, Purchaser shall send a written notice
to each Stockholder identifying the place and date (not less than two (2) nor
more than ten (10) business days from the date of the notice) for the closing of
such purchase.

     4. Additional Agreements.

     (a) Each Stockholder shall, at any meeting of the stockholders of the
Company, however called, or in connection with any written consent of the
stockholders of the Company, vote (or cause to be voted) all Shares then held of
record or beneficially owned by such Stockholder, (i) in favor of the Merger,
the execution and delivery by the Company of the Merger Agreement and the
approval of the terms thereof and each of the other actions contemplated by the
Merger Agreement and this Agreement and any actions required in furtherance
thereof and hereof and (ii) against any proposal relating to an Acquisition
Proposal and against any action or agreement that would impede, frustrate,
prevent or nullify this Agreement, or result in a breach in any respect of any
covenant, representation or warranty or any other obligation or agreement of the
Company under the Merger Agreement or which would result in any of the
conditions set forth in Annex A to the Merger Agreement or set forth in Article
VI of the Merger Agreement not being fulfilled.

     (b) Each Stockholder hereby covenants and agrees that, except as
contemplated by this Agreement and the Merger Agreement, it shall not (i) offer
to transfer (which term shall include, without limitation, any sale, tender,
gift, pledge, assignment or other disposition), transfer or consent to any
transfer of, any or all of the Stockholder Shares or any interest therein
without the prior written consent of Purchaser, (ii) enter into any contract,
option or other agreement or understanding with respect to any transfer or any
or all of the Stockholder Shares or any interest therein, (iii) grant any proxy,
power-of-attorney or other authorization or consent in or with respect to the
Stockholder Shares, (iv) deposit the Stockholder Shares into a voting trust or
enter into a voting agreement or arrangement with respect to the Stockholder
Shares or (v) take any other action that would make any representation or
warranty of the Stockholder contained herein untrue or incorrect in any material
respect or in any way restrict, limit or interfere in any material respect with
the performance of its obligations hereunder or the transactions contemplated
hereby or by the Merger Agreement.

     (c) Each Stockholder hereby irrevocably grants to, and appoints, Purchaser
and any designee of Purchaser, and each of them individually, such Stockholder's
proxy and attorney-in-fact with full power of substitution), for and in the
name, place and stead of such Stockholder, to vote the Stockholder Shares, or
grant a consent or approval in respect of the Stockholder Shares, in the manner
specified in Section 4(a). Each Stockholder represents that any proxies
heretofore given in respect of the Stockholder Shares are not irrevocable and
that any such proxies are hereby revoked. Each Stockholder hereby affirms that
the irrevocable proxy set forth in this Section 4(c) is given in connection with
the execution of the Merger Agreement and that such irrevocable proxy is given
to secure the performance of the duties of such Stockholder under this
Agreement. Each Stockholder hereby further affirms that the irrevocable proxy is
coupled with an interest and may under no circumstances be revoked. Each
Stockholder hereby ratifies and confirms all that such irrevocable proxy may
lawfully do or cause to be done by virtue hereof.

<PAGE>   3

     (d) Subject to Section 8, each Stockholder hereby agrees that such
Stockholder shall not, directly or indirectly, encourage, solicit, initiate or
participate in any way in any discussions or negotiations with, or provide any
information to, or afford any access to the properties, books or records of the
Company or any of its Subsidiaries to, or otherwise take any other action to
assist or facilitate, any Person or group (other than Parent or Purchaser or any
affiliate or associate of Parent or Purchaser) concerning any Acquisition
Proposal. Upon execution of this Agreement, each Stockholder will immediately
cease any existing activities, discussions or negotiations conducted heretofore
with respect to any Acquisition Proposal. Each Stockholder will immediately
communicate to Purchaser the terms of any Acquisition Proposal (or any
discussion, negotiation or inquiry with respect thereto) and the identity of the
Person making such Proposal or inquiry which it may receive.

     (e) Subject to the terms and conditions of this Agreement, each of the
parties hereto agrees to use all reasonable 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 to consummate and make effective the
transactions contemplated by this Agreement. Each party shall promptly consult
with the other and provide any necessary information and material with respect
to all filings made by such party with any Governmental Entity in connection
with this Agreement and the transactions contemplated hereby.

     (f) Each Stockholder hereby waives any rights of appraisal or rights to
dissent from the Merger that it may have.

     5. Representations and Warranties of each Stockholder. Each Stockholder, as
to itself and no other Stockholder, hereby represents and warrants to Purchaser
as follows:

all of the Stockholder's obligations under this Agreement. This Agreement has
been duly and validly executed and delivered by the Stockholder and constitutes

contemplated hereby and the compliance by the Stockholder with the provisions
hereof and (ii) none of the execution and delivery of this Agreement by the
Stockholder, the consummation by the Stockholder of the transactions
contemplated hereby or compliance by the Stockholder with any of the provisions
hereof, shall (A) conflict with or result in any breach of any organizational
documents applicable to the Stockholder, (B) result in a violation or breach of,
or constitute (with or without notice or lapse of time or both) a default (or
give rise to any third party right of termination, cancellation, modification or
acceleration) under, any of the terms, conditions or provisions of any note,
loan agreement, bond, mortgage, indenture, license, contract, commitment,
arrangement, understanding, agreement or other instrument or obligation of any
kind, including, without limitation, any voting agreement, proxy arrangement,
pledge agreement, shareholders agreement or voting trust, to which the

a nominee or custodian for the benefit of the Stockholder, free and clear of all
liens, proxies, voting trusts or agreements, understandings or arrangements or
any other rights whatsoever, except for any such liens or proxies arising
hereunder. The transfer by the Stockholder of the Stockholder Shares to
Purchaser in the Offer or hereunder shall pass to and unconditionally vest in

liens, proxies, voting trusts or agreements, understandings or arrangements or
any other rights whatsoever.

     (e) No broker, investment banker, financial advisor or other Person is

arrangements made by or on behalf of the Stockholder.

     6. Stop Transfer. Each Stockholder shall request that the Company not
register the transfer (book-entry or otherwise) of any certificate or
uncertificated interest representing any of the Stockholder Shares, unless such
transfer is made in compliance with this Agreement.

     7. Termination. This Agreement shall terminate upon the earlier of (a) the
Effective Time and (b) the termination of the Merger Agreement (unless, in the
case of this clause (b), Parent is or may be entitled to receive a Termination
Fee under the Merger Agreement following such termination or prior to such
termination any of the Stockholders has breached in any material respect Section
2(a), 4(a), 4(b) or 4(d)).

     8. No Limitation. Notwithstanding any other provision hereof, nothing in
this Agreement shall be construed to prohibit the Stockholders, or any officer
or affiliate of any of the Stockholders who is or has designated a member of the
Board of Directors of the Company, from taking any action solely in his or her
capacity as a member of the Board of Directors of the Company or from exercising
his or her fiduciary duties as a member of such Board of Directors to the extent
specifically permitted by the Merger Agreement.

respect to the subject matter hereof.

     (b) This Agreement shall not be assigned by operation of law or otherwise
without the prior written consent of each of the Stockholders (in the case of
any assignment by Purchaser) or Purchaser (in the case of an assignment by a
Stockholder), provided that Purchaser may assign its rights and obligations
hereunder to Parent or any direct or indirect Subsidiary of Parent, but no such
assignment shall relieve Purchaser of its obligations hereunder.

     (c) Without limiting any other rights Purchaser may have hereunder in
respect of any transfer of Shares, each Stockholder agrees that this Agreement

                             STOCKHOLDER AGREEMENT

     STOCKHOLDER AGREEMENT, dated as of November 18, 1999 (this "Agreement"),
among Forrest Acquisition Sub, Inc., a Delaware corporation ("Purchaser"), and
Philip Industrial Services Group, Inc. (the "Stockholder").

                                   RECITALS:

     WHEREAS, concurrently, with the execution and delivery of this Agreement,
Purchaser, Flowserve Corporation, a New York corporation ("Parent"), and
Innovative Valve Technologies, Inc., a Delaware corporation (the "Company"), are
entering into an Agreement and Plan of Merger (the "Merger Agreement"), which
provides, among other things, for the acquisition of the Company by Parent by
means of a cash tender offer (the "Offer") by Purchaser for all outstanding
shares of Common Stock, par value $0.001 per share, of the Company (the "Common
Stock"), including the associated preferred share purchase rights (the "Rights,"
and together with the Common Stock, the "Shares") and for the subsequent merger
of Purchaser with and into the Company (the "Merger"), all on the terms and
subject to the conditions set forth in the Merger Agreement;

     WHEREAS, the Stockholder has filed a voluntary petition under Chapter 11 of
the U.S. Bankruptcy Code with the Bankruptcy Court for the District of Delaware
(the "Bankruptcy Court"); and

     WHEREAS, as an inducement and a condition to entering into the Merger
Agreement, Parent and Purchaser have required that the Stockholder agree, and
the Stockholder has agreed, to enter into this Agreement; and

     WHEREAS, the Board of Directors of the Company has approved this Agreement
and the transactions contemplated hereby prior to the date hereof; and

     WHEREAS, the current board of directors of the Stockholder has approved
this Agreement and the transactions contemplated hereby prior to the date
hereof;

     NOW THEREFORE, in consideration of the foregoing and the mutual covenants
and agreements set forth herein, the parties hereto agree as follows:

     1. Definitions. Terms used and not defined herein, but defined in the
Merger Agreement, shall have the respective meanings ascribed to them in the
Merger Agreement.

     2. Tender of Shares; Agreement to Sell; Consideration.

          (a) In order to induce Parent and Purchaser to enter into the Merger
     Agreement, the Stockholder hereby agrees that, unless the Company shall
     have terminated the Merger Agreement to accept a Superior Proposal and
     subject to the approval of the Bankruptcy Court to the extent necessary, it
     shall validly tender (or cause the record owner of such shares to validly
     tender), and not to withdraw, pursuant to and in accordance with the terms
     of the Offer, not later than the tenth business day after commencement of
     the Offer (or if Bankruptcy Court approval of this Agreement pursuant to
     Section 3(e) is received or the Stockholder's plan of reorganization is
     confirmed by the Bankruptcy Court after such tenth business day, not later
     than the first business day after the earlier to occur of such approval or
     confirmation), the number of shares set forth opposite the Stockholder's
     name on Schedule I hereto (the "Existing Shares" and, together with any
     Shares acquired by the Stockholder in any capacity after the date hereof
     and prior to the termination of this Agreement by means of purchase,
     dividend, distribution, exercise of options, warrants or other rights to
     acquire Shares or in any other way, the "Stockholder Shares"), all of which
     are beneficially owned by the Stockholder. Unless the Company shall have
     terminated the Merger Agreement to accept a Superior Proposal and subject
     to the approval of the Bankruptcy Court to the extent necessary, if the
     Stockholder acquires beneficial ownership of Shares after the date hereof
     and prior to termination of this Agreement, the Stockholder shall tender
     such Shares on such tenth business day or, if later, on the second business
     day after such acquisition (or if Bankruptcy
<PAGE>   2

     Court approval of this Agreement pursuant to Section 3(e) is received or
     the Stockholder's plan of reorganization is confirmed after such tenth
     business day or such later date, not later than the first business day
     after the earlier to occur of such approval or confirmation).

          (b) Purchaser shall be entitled to deduct and withhold from the
     consideration otherwise payable hereunder to the Stockholder such amounts
     as are required to be withheld under the Internal Revenue Code of 1986, as
     amended (the "Code"), or any applicable provision of state, local or
     foreign tax law, as specified in the Offer Documents. To the extent that
     amounts are so withheld by Purchaser, such withheld amounts shall be
     treated for all purposes of this Agreement as having been paid to the
     Stockholder.

          (c) The Stockholder hereby permits Parent and Purchaser to publish and
     disclose in the Offer Documents and, if approval of the Company's
     stockholders is required under applicable law, the Proxy Statement
     (including all documents and schedules filed with the SEC) the
     Stockholder's identity and ownership of the Stockholder Shares and the
     nature of the Stockholder's commitments, arrangements and understandings
     under this Agreement.

          (d) Subject to paragraph 2(b) hereof, Purchaser shall purchase the
     Stockholder Shares for an aggregate price equal to the Offer Price
     multiplied by the number of Stockholder Shares and shall pay such amount as
     directed by Bankers Trust Company; provided, however, that this Agreement
     shall not be binding on the Stockholder unless the Offer Price shall equal
     or exceed $1.50 per share.

     3. Additional Agreements.

          (a) Except as otherwise contemplated by this Agreement, the
     Stockholder shall, at any meeting of the stockholders of the Company,
     however called, or in connection with any written consent of the
     stockholders of the Company, vote (or cause to be voted) all Shares then
     held of record or beneficially owned by the Stockholder, (i) in favor of
     the Merger, the execution and delivery by the Company of the Merger
     Agreement and the approval of the terms thereof and each of the other
     actions contemplated by the Merger Agreement and this Agreement and any
     actions required in furtherance thereof and hereof and (ii) against any
     proposal relating to an Acquisition Proposal and against any action or
     agreement that would impede, frustrate, prevent or nullify this Agreement,
     or result in a breach in any respect of any covenant, representation or
     warranty or any other obligation or agreement of the Company under the
     Merger Agreement or which would result in any of the conditions set forth
     in Annex A to the Merger Agreement or set forth in Article VI of the Merger
     Agreement not being fulfilled.

          (b) The Stockholder hereby covenants and agrees that, except as
     contemplated by this Agreement and the Merger Agreement, it shall not (i)
     offer to transfer (which term shall include, without limitation, any sale,
     tender, gift, pledge, assignment or other disposition), transfer or consent
     to any transfer of, any or all of the Stockholder Shares or any interest
     therein without the prior written consent of Purchaser, (ii) enter into any
     contract, option or other agreement or understanding with respect to any
     transfer or any or all of the Stockholder Shares or any interest therein,
     (iii) grant any proxy, power-of-attorney or other authorization or consent
     in or with respect to the Stockholder Shares, (iv) deposit the Stockholder
     Shares into a voting trust or enter into a voting agreement or arrangement
     with respect to the Stockholder Shares or (v) take any other action that
     would make any representation or warranty of the Stockholder contained
     herein untrue or incorrect in any material respect or in any way restrict,
     limit or interfere in any material respect with the performance of its
     obligations hereunder or the transactions contemplated hereby or by the
     Merger Agreement.

          (c) Except as otherwise contemplated by this Agreement, the
     Stockholder hereby irrevocably grants to, and appoints, Purchaser and any
     designee of Purchaser, and each of them individually, the Stockholder's
     proxy and attorney-in-fact with full power of substitution, for and in the
     name, place and stead of the Stockholder, to vote the Stockholder Shares,
     or grant a consent or approval in respect of the Stockholder Shares, in the
     manner specified in Section 3(a). The Stockholder represents that any
     proxies heretofore given in respect of the Stockholder Shares are not
     irrevocable and that any such proxies are hereby revoked. The Stockholder
     hereby affirms that the irrevocable proxy set forth in this Section 3(c)
                                        2
<PAGE>   3

     is given in connection with the execution of the Merger Agreement and that
     such irrevocable proxy is given to secure the performance of the duties of
     the Stockholder under this Agreement. The Stockholder hereby further
     affirms that the irrevocable proxy is coupled with an interest and may
     under no circumstances be revoked, unless this Agreement is terminated
     under Section 6. The Stockholder hereby ratifies and confirms all that such
     irrevocable proxy may lawfully do or cause to be done by virtue hereof.

          (d) Subject to Section 7, the Stockholder hereby agrees that the
     Stockholder shall not, directly or indirectly, encourage, solicit, initiate
     or participate in any way in any discussions or negotiations with, or
     provide any information to, or afford any access to the properties, books
     or records of the Company or any of its Subsidiaries to, or otherwise take
     any other action to assist or facilitate, any Person or group (other than
     Parent or Purchaser or any affiliate or associate of Parent or Purchaser)
     concerning any Acquisition Proposal. Upon execution of this Agreement, the
     Stockholder will immediately cease any existing activities, discussions or
     negotiations conducted heretofore with respect to any Acquisition Proposal.
     The Stockholder will immediately communicate to Purchaser the terms of any
     Acquisition Proposal (or any discussion, negotiation or inquiry with
     respect thereto) and the identity of the Person making such Proposal or
     inquiry which it may receive.

          (e) The Stockholder hereby covenants and agrees that as soon as
     practicable following public announcement by Parent of the execution of the
     Merger Agreement, it will file, or cause to be filed, a petition with the
     Bankruptcy Court requesting the approval of this Agreement and the
     transactions contemplated hereby. The Stockholder shall deliver a copy of
     such petition to Purchaser's counsel for review at least two business days
     prior to such filing and shall promptly notify Purchaser of any action
     taken by the Bankruptcy Court with respect to the approval of this
     Agreement or the confirmation of a plan of reorganization regarding the
     Stockholder.

          (f) Subject to the terms and conditions of this Agreement, each of the
     parties hereto agrees to use all reasonable 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 to consummate and make effective
     the transactions contemplated by this Agreement. Each party shall promptly
     consult with the other and provide any necessary information and material
     with respect to all filings made by such party with any Governmental Entity
     in connection with this Agreement and the transactions contemplated hereby.

          (g) The Stockholder hereby waives any rights of appraisal or rights to
     dissent from the Merger that it may have.

          (h) The Stockholder shall use its best efforts to secure the Agent's
     Consent (as defined) as soon as practicable and, upon receipt thereof,
     shall deliver a copy of same to Purchaser.

     4. Representations and Warranties of each Stockholder. The Stockholder
hereby represents and warrants to Purchaser as follows:

          (a) The Stockholder is the record and beneficial owner of the Existing
     Shares set forth opposite its name on Schedule I. The Existing Shares
     constitute all of the Shares owned of record or beneficially owned by the
     Stockholder on the date hereof. The Stockholder has sole voting power and
     sole power to issue instructions with respect to the matters set forth in
     Sections 2 and 3 hereof, sole power of disposition, sole power to demand
     and waive appraisal rights and sole power to agree to all of the matters
     set forth in this Agreement, in each case with respect to all of the
     Existing Shares with no limitations, qualifications or restrictions on such
     rights, subject to (i) applicable securities laws, (ii) the terms of this
     Agreement, and (iii) the earlier to occur of the approval of this Agreement
     and the transactions contemplated hereby by the Bankruptcy Court and the
     confirmation of the Stockholder's plan of reorganization by the Bankruptcy
     Court.

          (b) The Stockholder has the power and authority to enter into and
     perform all of the Stockholder's obligations under this Agreement, subject

     transactions contemplated hereby by the Bankruptcy Court and the
     confirmation of the Stockholder's plan of reorganization by the Bankruptcy
     Court and further subject to the receipt by the Stockholder of a

     consent from the agent bank on behalf of the lending banks to the
     Stockholder under the Stockholder's principal bank credit arrangement (the
     "Agent's Consent"). This Agreement has been duly and validly executed and
     delivered by the Stockholder and, subject to the earlier to occur of the
     approval of this Agreement and the transactions contemplated hereby by the
     Bankruptcy Court and the confirmation of the Stockholder's plan or
     reorganization by the Bankruptcy Court and further subject to the receipt
     by the Stockholder of the Agent's Consent, constitutes a legal, valid and
     binding agreement of the Stockholder, enforceable against the Stockholder
     in accordance with its terms. There is no beneficiary or holder of a voting
     trust certificate or other interest of any trust of which the Stockholder
     is a trustee, or any party to any other agreement or arrangement, whose
     consent is required for the execution and delivery of this Agreement or the
     consummation by the Stockholder of the transactions contemplated hereby,
     other than the earlier to occur of the approval of this Agreement and the
     transactions contemplated hereby by the Bankruptcy Court and the
     confirmation of the Stockholder's plan of reorganization by the Bankruptcy
     Court.

          (c) Except for filings under the HSR Act and the Exchange Act, and
     subject to the earlier to occur of the approval of this Agreement and the
     transactions contemplated hereby by the Bankruptcy Court and the
     confirmation of the Stockholder's plan of reorganization by the Bankruptcy
     Court and further subject to the receipt by the Stockholder of the Agent's
     Consent, (i) no filing with, and no permit, authorization, consent or
     approval of, any Governmental Entity is necessary for the execution and
     delivery of this Agreement by the Stockholder, the consummation by such
     Stockholder of the transactions contemplated hereby and the compliance by
     the Stockholder with the provisions hereof, and (ii) none of the execution
     and delivery of this Agreement by the Stockholder, the consummation by the
     Stockholder of the transactions contemplated hereby or compliance by the
     Stockholder with any of the provisions hereof, shall (A) conflict with or
     result in any breach of any organizational documents applicable to the
     Stockholder, (B) result in a violation or breach of, or constitute (with or
     without notice or lapse of time or both) a default (or give rise to any
     third party right of termination, cancellation, modification or
     acceleration) under, any of the terms, conditions or provisions of any
     note, loan agreement, bond, mortgage, indenture, license, contract,
     commitment, arrangement, understanding, agreement or other instrument or
     obligation of any kind, including, without limitation, any voting
     agreement, proxy arrangement, pledge agreement, shareholders agreement or
     voting trust, to which the Stockholder is a party or by which it or any of
     its properties or assets may be bound or (C) violate any order, writ,
     injunction, decree, judgment, order, statute, rule or regulation applicable
     to the Stockholder or any of its properties or assets.

          (d) Upon the payment by Purchaser of the Offer Price per share for the
     Stockholder Shares as directed by Bankers Trust Company, the transfer by
     the Stockholder of the Stockholder Shares to Purchaser in the Offer or
     hereunder shall pass to and unconditionally vest in Purchaser good and
     valid title to all Stockholder Shares, free and clear of all liens,
     proxies, voting trusts or agreements, understandings or arrangements or any
     other rights whatsoever, subject to the earlier to occur of the approval of
     this Agreement and the transactions contemplated hereby by the Bankruptcy
     Court and the confirmation of the Stockholder's plan of reorganization by
     the Bankruptcy Court.

          (e) No broker, investment banker, financial advisor or other Person is
     entitled to any broker's, finder's, financial advisor's or other similar
     fee or commission in connection with the transactions contemplated hereby
     based upon arrangements made by or on behalf of the Stockholder.

          (f) The required number of the Stockholder's lenders have executed a
     resolution authorizing the Stockholder to enter into the transactions
     contemplated by this Agreement.

     5. Stop Transfer. The Stockholder shall request that the Company not
register the transfer (book-entry or otherwise) of any certificate or
uncertificated interest representing any of the Stockholder Shares, unless such
transfer is made in compliance with this Agreement.

     6. Termination. This Agreement shall terminate upon the earlier of (a) the
Effective Time and (b) the termination of the Merger Agreement (unless, in the
case of this clause (b), Parent is or may be entitled to

or prior to such termination the Stockholder has breached in any material
respect Section 2(a), 3(a), 3(b) or 3(d)).

this Agreement shall be construed to prohibit the Stockholder, or any officer or
affiliate of the Stockholder who is or has designated a member of the Board of
Directors of the Company, from taking any action solely in his or her capacity
as a member of the Board of Directors of the Company or from exercising his or
her fiduciary duties as a member of such Board of Directors to the extent
specifically permitted by the Merger Agreement.

     8. Stockholder's Fiduciary Obligation. Notwithstanding anything contained
herein to the contrary, Stockholder shall have the right to take or refrain from
taking any such acts as it shall have reasonably determined are necessary to
fulfill its fiduciary obligations as a debtor and debtor in possession,
including, but not limited to, the right to withdraw the Shares tendered
pursuant to the Offer and to entertain and, if appropriate, accept any higher
and better offers to purchase the Shares, and Stockholder shall not be deemed to
be in breach of any provision of this Agreement as a result of taking any such
action or refraining from taking any such action, provided that Stockholder
shall furnish Purchaser with written notice of the terms of any competing offer
to purchase the Shares and shall provide Purchaser a reasonable opportunity to
match any such competing offer.

     otherwise without the prior written consent of the Stockholder (in the case
     of any assignment by Purchaser) or Purchaser (in the case of an assignment
     by the Stockholder), provided that Purchaser may assign its rights and

     Parent, but no such assignment shall relieve Purchaser of its obligations
     hereunder.

                             STOCKHOLDER AGREEMENT

     STOCKHOLDER AGREEMENT, dated as of November 18, 1999 (this "Agreement"),
among Forrest Acquisition Sub, Inc., a Delaware corporation ("Purchaser"), and
Philip Environmental Services, Inc. (the "Stockholder").

                                   RECITALS:

     WHEREAS, concurrently, with the execution and delivery of this Agreement,
Purchaser, Flowserve Corporation, a New York corporation ("Parent"), and
Innovative Valve Technologies, Inc., a Delaware corporation (the "Company"), are
entering into an Agreement and Plan of Merger (the "Merger Agreement"), which
provides, among other things, for the acquisition of the Company by Parent by
means of a cash tender offer (the "Offer") by Purchaser for all outstanding
shares of Common Stock, par value $0.001 per share, of the Company (the "Common
Stock"), including the associated preferred share purchase rights (the "Rights,"
and together with the Common Stock, the "Shares") and for the subsequent merger
of Purchaser with and into the Company (the "Merger"), all on the terms and
subject to the conditions set forth in the Merger Agreement;

     WHEREAS, the Stockholder has filed a voluntary petition under Chapter 11 of
the U.S. Bankruptcy Code with the Bankruptcy Court for the District of Delaware
(the "Bankruptcy Court"); and

     WHEREAS, as an inducement and a condition to entering into the Merger
Agreement, Parent and Purchaser have required that the Stockholder agree, and
the Stockholder has agreed, to enter into this Agreement; and

     WHEREAS, the Board of Directors of the Company has approved this Agreement
and the transactions contemplated hereby prior to the date hereof; and

     WHEREAS, the current board of directors of the Stockholder has approved
this Agreement and the transactions contemplated hereby prior to the date
hereof;

     NOW THEREFORE, in consideration of the foregoing and the mutual covenants
and agreements set forth herein, the parties hereto agree as follows:

     1. Definitions. Terms used and not defined herein, but defined in the
Merger Agreement, shall have the respective meanings ascribed to them in the
Merger Agreement.

     2. Tender of Shares; Agreement to Sell; Consideration.

          (a) In order to induce Parent and Purchaser to enter into the Merger
     Agreement, the Stockholder hereby agrees that, unless the Company shall
     have terminated the Merger Agreement to accept a Superior Proposal and
     subject to the approval of the Bankruptcy Court to the extent necessary, it
     shall validly tender (or cause the record owner of such shares to validly
     tender), and not to withdraw, pursuant to and in accordance with the terms
     of the Offer, not later than the tenth business day after commencement of
     the Offer (or if Bankruptcy Court approval of this Agreement pursuant to
     Section 3(e) is received or the Stockholder's plan of reorganization is
     confirmed by the Bankruptcy Court after such tenth business day, not later
     than the first business day after the earlier to occur of such approval or
     confirmation), the number of shares set forth opposite the Stockholder's
     name on Schedule I hereto (the "Existing Shares" and, together with any
     Shares acquired by the Stockholder in any capacity after the date hereof
     and prior to the termination of this Agreement by means of purchase,
     dividend, distribution, exercise of options, warrants or other rights to
     acquire Shares or in any other way, the "Stockholder Shares"), all of which
     are beneficially owned by the Stockholder. Unless the Company shall have
     terminated the Merger Agreement to accept a Superior Proposal and subject
     to the approval of the Bankruptcy Court to the extent necessary, if the
     Stockholder acquires beneficial ownership of Shares after the date hereof
     and prior to termination of this Agreement, the Stockholder shall tender
     such Shares on such tenth business day or, if later, on the second business
     day after such acquisition (or if Bankruptcy
<PAGE>   2

     Court approval of this Agreement pursuant to Section 3(e) is received or
     the Stockholder's plan of reorganization is confirmed after such tenth
     business day or such later date, not later than the first business day
     after the earlier to occur of such approval or confirmation).

          (b) Purchaser shall be entitled to deduct and withhold from the
     consideration otherwise payable hereunder to the Stockholder such amounts
     as are required to be withheld under the Internal Revenue Code of 1986, as
     amended (the "Code"), or any applicable provision of state, local or
     foreign tax law, as specified in the Offer Documents. To the extent that
     amounts are so withheld by Purchaser, such withheld amounts shall be
     treated for all purposes of this Agreement as having been paid to the
     Stockholder.

          (c) The Stockholder hereby permits Parent and Purchaser to publish and
     disclose in the Offer Documents and, if approval of the Company's
     stockholders is required under applicable law, the Proxy Statement
     (including all documents and schedules filed with the SEC) the
     Stockholder's identity and ownership of the Stockholder Shares and the
     nature of the Stockholder's commitments, arrangements and understandings
     under this Agreement.

          (d) Subject to paragraph 2(b) hereof, Purchaser shall purchase the
     Stockholder Shares for an aggregate price equal to the Offer Price
     multiplied by the number of Stockholder Shares and shall pay such amount as
     directed by Bankers Trust Company; provided, however, that this Agreement
     shall not be binding on the Stockholder unless the Offer Price shall equal
     or exceed $1.50 per share.

     3. Additional Agreements.

          (a) Except as otherwise contemplated by this Agreement, the
     Stockholder shall, at any meeting of the stockholders of the Company,
     however called, or in connection with any written consent of the
     stockholders of the Company, vote (or cause to be voted) all Shares then
     held of record or beneficially owned by the Stockholder, (i) in favor of
     the Merger, the execution and delivery by the Company of the Merger
     Agreement and the approval of the terms thereof and each of the other
     actions contemplated by the Merger Agreement and this Agreement and any
     actions required in furtherance thereof and hereof and (ii) against any
     proposal relating to an Acquisition Proposal and against any action or
     agreement that would impede, frustrate, prevent or nullify this Agreement,
     or result in a breach in any respect of any covenant, representation or
     warranty or any other obligation or agreement of the Company under the
     Merger Agreement or which would result in any of the conditions set forth
     in Annex A to the Merger Agreement or set forth in Article VI of the Merger
     Agreement not being fulfilled.

          (b) The Stockholder hereby covenants and agrees that, except as
     contemplated by this Agreement and the Merger Agreement, it shall not (i)
     offer to transfer (which term shall include, without limitation, any sale,
     tender, gift, pledge, assignment or other disposition), transfer or consent
     to any transfer of, any or all of the Stockholder Shares or any interest
     therein without the prior written consent of Purchaser, (ii) enter into any
     contract, option or other agreement or understanding with respect to any
     transfer or any or all of the Stockholder Shares or any interest therein,
     (iii) grant any proxy, power-of-attorney or other authorization or consent
     in or with respect to the Stockholder Shares, (iv) deposit the Stockholder
     Shares into a voting trust or enter into a voting agreement or arrangement
     with respect to the Stockholder Shares or (v) take any other action that
     would make any representation or warranty of the Stockholder contained
     herein untrue or incorrect in any material respect or in any way restrict,
     limit or interfere in any material respect with the performance of its
     obligations hereunder or the transactions contemplated hereby or by the
     Merger Agreement.

          (c) Except as otherwise contemplated by this Agreement, the
     Stockholder hereby irrevocably grants to, and appoints, Purchaser and any
     designee of Purchaser, and each of them individually, the Stockholder's
     proxy and attorney-in-fact with full power of substitution, for and in the
     name, place and stead of the Stockholder, to vote the Stockholder Shares,
     or grant a consent or approval in respect of the Stockholder Shares, in the
     manner specified in Section 3(a). The Stockholder represents that any
     proxies heretofore given in respect of the Stockholder Shares are not
     irrevocable and that any such proxies are hereby revoked. The Stockholder
     hereby affirms that the irrevocable proxy set forth in this Section 3(c)
                                        2
<PAGE>   3

     is given in connection with the execution of the Merger Agreement and that
     such irrevocable proxy is given to secure the performance of the duties of
     the Stockholder under this Agreement. The Stockholder hereby further
     affirms that the irrevocable proxy is coupled with an interest and may
     under no circumstances be revoked, unless this Agreement is terminated
     under Section 6. The Stockholder hereby ratifies and confirms all that such
     irrevocable proxy may lawfully do or cause to be done by virtue hereof.

          (d) Subject to Section 7, the Stockholder hereby agrees that the
     Stockholder shall not, directly or indirectly, encourage, solicit, initiate
     or participate in any way in any discussions or negotiations with, or
     provide any information to, or afford any access to the properties, books
     or records of the Company or any of its Subsidiaries to, or otherwise take
     any other action to assist or facilitate, any Person or group (other than
     Parent or Purchaser or any affiliate or associate of Parent or Purchaser)
     concerning any Acquisition Proposal. Upon execution of this Agreement, the
     Stockholder will immediately cease any existing activities, discussions or
     negotiations conducted heretofore with respect to any Acquisition Proposal.
     The Stockholder will immediately communicate to Purchaser the terms of any
     Acquisition Proposal (or any discussion, negotiation or inquiry with

     inquiry which it may receive.

          (e) The Stockholder hereby covenants and agrees that as soon as
     practicable following public announcement by Parent of the execution of the
     Merger Agreement, it will file, or cause to be filed, a petition with the
     Bankruptcy Court requesting the approval of this Agreement and the
     transactions contemplated hereby. The Stockholder shall deliver a copy of
     such petition to Purchaser's counsel for review at least two business days
     prior to such filing and shall promptly notify Purchaser of any action
     taken by the Bankruptcy Court with respect to the approval of this
     Agreement or the confirmation of a plan of reorganization regarding the
     Stockholder.

          (f) Subject to the terms and conditions of this Agreement, each of the
     parties hereto agrees to use all reasonable 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 to consummate and make effective
     the transactions contemplated by this Agreement. Each party shall promptly
     consult with the other and provide any necessary information and material
     with respect to all filings made by such party with any Governmental Entity
     in connection with this Agreement and the transactions contemplated hereby.

          (g) The Stockholder hereby waives any rights of appraisal or rights to
     dissent from the Merger that it may have.

          (h) The Stockholder shall use its best efforts to secure the Agent's
     Consent (as defined) as soon as practicable and, upon receipt thereof,
     shall deliver a copy of same to Purchaser.

     4. Representations and Warranties of each Stockholder. The Stockholder
hereby represents and warrants to Purchaser as follows:

          (a) The Stockholder is the record and beneficial owner of the Existing
     Shares set forth opposite its name on Schedule I. The Existing Shares
     constitute all of the Shares owned of record or beneficially owned by the
     Stockholder on the date hereof. The Stockholder has sole voting power and
     sole power to issue instructions with respect to the matters set forth in
     Sections 2 and 3 hereof, sole power of disposition, sole power to demand
     and waive appraisal rights and sole power to agree to all of the matters
     set forth in this Agreement, in each case with respect to all of the
     Existing Shares with no limitations, qualifications or restrictions on such
     rights, subject to (i) applicable securities laws, (ii) the terms of this
     Agreement, and (iii) the earlier to occur of the approval of this Agreement
     and the transactions contemplated hereby by the Bankruptcy Court and the
     confirmation of the Stockholder's plan of reorganization by the Bankruptcy
     Court.

          (b) The Stockholder has the power and authority to enter into and
     perform all of the Stockholder's obligations under this Agreement, subject

     transactions contemplated hereby by the Bankruptcy Court and the
     confirmation of the Stockholder's plan of reorganization by the Bankruptcy
     Court and further subject to the receipt by the Stockholder of a

                                        3
<PAGE>   4

     consent from the agent bank on behalf of the lending banks to the
     Stockholder under the Stockholder's principal bank credit arrangement (the
     "Agent's Consent"). This Agreement has been duly and validly executed and
     delivered by the Stockholder and, subject to the earlier to occur of the
     approval of this Agreement and the transactions contemplated hereby by the
     Bankruptcy Court and the confirmation of the Stockholder's plan or
     reorganization by the Bankruptcy Court and further subject to the receipt
     by the Stockholder of the Agent's Consent, constitutes a legal, valid and
     binding agreement of the Stockholder, enforceable against the Stockholder
     in accordance with its terms. There is no beneficiary or holder of a voting
     trust certificate or other interest of any trust of which the Stockholder
     is a trustee, or any party to any other agreement or arrangement, whose
     consent is required for the execution and delivery of this Agreement or the
     consummation by the Stockholder of the transactions contemplated hereby,
     other than the earlier to occur of the approval of this Agreement and the
     transactions contemplated hereby by the Bankruptcy Court and the
     confirmation of the Stockholder's plan of reorganization by the Bankruptcy
     Court.

          (c) Except for filings under the HSR Act and the Exchange Act, and
     subject to the earlier to occur of the approval of this Agreement and the
     transactions contemplated hereby by the Bankruptcy Court and the
     confirmation of the Stockholder's plan of reorganization by the Bankruptcy
     Court and further subject to the receipt by the Stockholder of the Agent's
     Consent, (i) no filing with, and no permit, authorization, consent or
     approval of, any Governmental Entity is necessary for the execution and
     delivery of this Agreement by the Stockholder, the consummation by such
     Stockholder of the transactions contemplated hereby and the compliance by
     the Stockholder with the provisions hereof, and (ii) none of the execution
     and delivery of this Agreement by the Stockholder, the consummation by the
     Stockholder of the transactions contemplated hereby or compliance by the
     Stockholder with any of the provisions hereof, shall (A) conflict with or
     result in any breach of any organizational documents applicable to the
     Stockholder, (B) result in a violation or breach of, or constitute (with or
     without notice or lapse of time or both) a default (or give rise to any
     third party right of termination, cancellation, modification or
     acceleration) under, any of the terms, conditions or provisions of any
     note, loan agreement, bond, mortgage, indenture, license, contract,
     commitment, arrangement, understanding, agreement or other instrument or
     obligation of any kind, including, without limitation, any voting
     agreement, proxy arrangement, pledge agreement, shareholders agreement or
     voting trust, to which the Stockholder is a party or by which it or any of
     its properties or assets may be bound or (C) violate any order, writ,
     injunction, decree, judgment, order, statute, rule or regulation applicable
     to the Stockholder or any of its properties or assets.

          (d) Upon the payment by Purchaser of the Offer Price per share for the
     Stockholder Shares as directed by Bankers Trust Company, the transfer by
     the Stockholder of the Stockholder Shares to Purchaser in the Offer or
     hereunder shall pass to and unconditionally vest in Purchaser good and
     valid title to all Stockholder Shares, free and clear of all liens,
     proxies, voting trusts or agreements, understandings or arrangements or any
     other rights whatsoever, subject to the earlier to occur of the approval of
     this Agreement and the transactions contemplated hereby by the Bankruptcy
     Court and the confirmation of the Stockholder's plan of reorganization by
     the Bankruptcy Court.

          (e) No broker, investment banker, financial advisor or other Person is
     entitled to any broker's, finder's, financial advisor's or other similar
     fee or commission in connection with the transactions contemplated hereby
     based upon arrangements made by or on behalf of the Stockholder.

          (f) The required number of the Stockholder's lenders have executed a
     resolution authorizing the Stockholder to enter into the transactions
     contemplated by this Agreement.

     5. Stop Transfer. The Stockholder shall request that the Company not
register the transfer (book-entry or otherwise) of any certificate or
uncertificated interest representing any of the Stockholder Shares, unless such
transfer is made in compliance with this Agreement.

     6. Termination. This Agreement shall terminate upon the earlier of (a) the
Effective Time and (b) the termination of the Merger Agreement (unless, in the
case of this clause (b), Parent is or may be entitled to

or prior to such termination the Stockholder has breached in any material
respect Section 2(a), 3(a), 3(b) or 3(d)).

     7. No Limitation. Notwithstanding any other provision hereof, nothing in
this Agreement shall be construed to prohibit the Stockholder, or any officer or
affiliate of the Stockholder who is or has designated a member of the Board of
Directors of the Company, from taking any action solely in his or her capacity
as a member of the Board of Directors of the Company or from exercising his or
her fiduciary duties as a member of such Board of Directors to the extent
specifically permitted by the Merger Agreement.

     8. Stockholder's Fiduciary Obligation. Notwithstanding anything contained
herein to the contrary, Stockholder shall have the right to take or refrain from
taking any such acts as it shall have reasonably determined are necessary to
fulfill its fiduciary obligations as a debtor and debtor in possession,
including, but not limited to, the right to withdraw the Shares tendered
pursuant to the Offer and to entertain and, if appropriate, accept any higher
and better offers to purchase the Shares, and Stockholder shall not be deemed to
be in breach of any provision of this Agreement as a result of taking any such
action or refraining from taking any such action, provided that Stockholder
shall furnish Purchaser with written notice of the terms of any competing offer
to purchase the Shares and shall provide Purchaser a reasonable opportunity to
match any such competing offer.

     9. Miscellaneous.

     parties with respect to the subject matter hereof and supersedes all other
     prior agreements and understandings, both written and oral, between the
     parties with respect to the subject matter hereof.

          (b) This Agreement shall not be assigned by operation of law or
     otherwise without the prior written consent of the Stockholder (in the case
     of any assignment by Purchaser) or Purchaser (in the case of an assignment
     by the Stockholder), provided that Purchaser may assign its rights and
     obligations hereunder to Parent or any direct or indirect Subsidiary of
     Parent, but no such assignment shall relieve Purchaser of its obligations
     hereunder.

          (c) Without limiting any other rights Purchaser may have hereunder in
     respect of any transfer of Shares, the Stockholder agrees that this
     Agreement and the obligations hereunder shall attach to the Stockholder
     Shares and shall be binding upon any Person to which legal or beneficial
     ownership of such Shares shall pass, whether by operation of law or
     otherwise, including, without limitation, such Stockholder's heirs,
     guardians, administrators or successors.

          (d) This Agreement may not be amended, changed, supplemented or
     otherwise modified with respect to the Stockholder except by an instrument
     in writing signed on behalf of such Stockholder and Purchaser.

Attention: Charles Schugart, President

         RE: Forrest/Servco Transaction (All terms used herein shall have the
             definitions ascribed to them in the 10/22/99 draft Agreement and
             Plan of Merger between Forrest, Forrest Acquisition Sub, Inc. and
             Servco)

Dear Charles:

     As we discussed by telephone on October 28, 1999, Parent has incurred, and
is continuing to incur, substantial out-of-pocket fees and expenses in
connection with the proposed transaction with the Company. As an inducement for
Parent to continue incurring such fees and expenses and in light of the
unexpected volatility in the trading price of the Common Stock and resulting
uncertainty that it creates for a transaction being consummated, the Company
agrees that if within six months of the date hereof an Acquisition Proposal is
accepted and the related transaction consummated pursuant to a definitive
agreement or otherwise, then in such event the Company shall pay to Parent
(within two business days after the Company consummates any such Acquisition
Proposal) an amount equal to the out-of-pocket fees and expenses incurred by
Parent and Purchaser in connection with the Offer, the Merger, the Agreement and
the consummation of the transactions contemplated thereby.

     The terms and provisions of this letter shall terminate upon the earlier of
six months from the date hereof and the execution of a definitive Agreement.

     Please confirm that the foregoing accurately states our agreement by
signing and returning the duplicate original of this letter.

                                            Sincerely,

                                                    /s/ RONALD SHUFF
