                               SUMMARY TERM SHEET

   The following are some of the questions you may have and our answers to
those questions. Please read carefully the remainder of this offer to purchase
and the enclosed letter of transmittal. The information in this section is only
a summary, is not complete and may not contain all the information that may be
important to you. Questions or requests for assistance may be directed to the
Information Agent or the Dealer Manager at their addresses and telephone
numbers listed on the last page of this offer to purchase.

What are Parker-Hannifin Corporation and Wynn's International, Inc. proposing?

   Parker-Hannifin Corporation (the "Purchaser") and Wynn's International, Inc.
(the "Company") have entered into a merger agreement pursuant to which WI
Holding Inc., a wholly owned subsidiary of the Purchaser ("Merger Sub"), is
offering to purchase all of the outstanding common stock of the Company for
$23.00 per share, net to you, in cash.

Who is offering to buy my securities?

   The Purchaser is offering to buy your securities through Merger Sub, a
Delaware corporation formed for the purpose of making a tender offer for all of
the outstanding shares of common stock of the Company.

How much are you offering to pay and what is the form of payment?

   We are offering to pay $23.00 per share, net to you, in cash. Tendering
stockholders will not be obligated to pay brokerage fees or commissions or,
except as set forth in Instruction 6 of the letter of transmittal, stock
transfer taxes on the purchase of shares by the Merger Sub pursuant to the
offer.

Do you have the financial resources to make payment?

   The Purchaser will provide Merger Sub with the funds required to pay for the
shares. The Purchaser will finance the purchase with funds borrowed pursuant to
its existing commercial paper program and funds raised through the sale of debt
securities under its existing "shelf" registration statement. The offer is not
contingent on obtaining any financing. (See page 32)

Is your financial condition relevant to my decision on whether to tender in the
offer?

   We do not think our financial condition is relevant to your decision whether
to tender shares and accept the offer because:

  -- the offer is being made for all outstanding shares solely for cash;

  -- the offer is not subject to any financing condition; and

  -- if we consummate the offer, we will acquire all remaining shares for the
     same cash price in the merger of the Company with Merger Sub.

Is the offer contingent on the purchase of a specified number of Shares by
Merger Sub?

   Yes. The offer is contingent on, among other things, there being tendered to
Merger Sub at least a majority of the Company's common stock on a fully diluted
basis.


                                       1
<PAGE>

How long do I have to decide whether to tender in the offer?

   You will have until 12:00 midnight, New York City time, on Thursday, July
20, 2000 to decide whether to tender your shares in the offer, unless the offer
is extended. If you cannot deliver everything that is required to make a valid
tender by that time, you may be able to use a guaranteed delivery procedure,
which is described later in this offer to purchase. (See page 10)

Can the offer be extended and under what circumstances?

   We can extend the offer, if the conditions to the offer have not been
earlier waived or satisfied, through Tuesday, August 15, 2000. Also, the offer
will be extended if on any scheduled expiration date the parties have not
obtained all of the required regulatory approvals for the offer and the merger
provided, that each party shall have the right to terminate the Merger
Agreement if the Offer is not completed by December 15, 2000. (See page 28)

   We may also elect to provide a "subsequent offering period" for the offer. A
subsequent offering period, if one is included, will be an additional period of
time beginning after we have purchased shares tendered during the offer, during
which stockholders may tender their shares and receive the offer consideration.
We do not currently intend to have a subsequent offering period, although we
reserve the right to do so. (See page 8)

How will I be notified if the offer is extended?

   If we extend the offer, we will make a public announcement of the extension,
no later than 9:00 a.m., New York City time, on the day after the day on which
the offer was previously scheduled to expire.

What are the most significant conditions to the offer?

   We are not obligated to purchase any tendered shares unless the number of
shares tendered equals at least a majority of the outstanding shares of the
Company on a fully diluted basis. We are also not obligated to purchase shares
if there is a material adverse change in the Company or its business. Please
see pages 33 to 36 for a summary of these and other conditions to the offer.

How do I tender my shares?

   If you hold your shares in your own name, you can tender your shares by:

  .  completing the enclosed letter of transmittal; and

  .  mailing your stock certificates along with the letter of transmittal to
     the depositary in the enclosed envelope.

   If your stock certificates are not immediately available, you may elect to
follow the guaranteed delivery procedures described on page 10.

   If your shares are held in the name of your broker, bank or other nominee,
you must instruct your nominee to tender your shares on your behalf by
completing the form sent to you by the nominee and returning the form to it.

What is the latest date that I can withdraw previously tendered shares?

   In general, you can withdraw your previously tendered shares at any time
before the offer expires. (See page 12)


                                       2
<PAGE>

How do I withdraw previously tendered shares?

   You may withdraw tendered shares any time before the offer expires by
mailing or faxing your notice of withdrawal to the depositary if your shares
are held in your name or to your broker or bank if they are held in your
broker's or bank's name. In general, for the notice of withdrawal to be
effective, the depositary must receive your notice before the offer expires.
(See page 12)

What does the Company's Board of Directors think of the offer?

   The Company's Board of Directors unanimously determined that the offer, the
offer price, and the merger are fair to you and in your best interests. They
unanimously recommend that you accept the offer and tender your shares pursuant
to the offer.

Did the Company's Board of Directors receive a fairness opinion?

   Yes. J.P. Morgan Securities Inc. ("J.P. Morgan"), the Company's financial
advisor, delivered to the Board of Directors of the Company a written opinion,
dated June 13, 2000, to the effect that, as of such date and subject to the
assumptions and considerations described in the opinion, the offer price of
$23.00 per share is fair, from a financial point of view, to the Company's
stockholders. The complete opinion of J.P. Morgan is attached to the Company's
Solicitation/Recommendation Statement on Schedule 14D-9, which is being mailed
to stockholders with this document. We urge you to read it.

Has any stockholder agreed to tender his or her shares?

   Yes. James Carroll, Chairman of the Board and Chief Executive Officer of the
Company, who beneficially owns 1,086,903 shares of the outstanding common stock
of the Company (or 5.5% on a fully diluted basis), has agreed to tender his
shares in the offer. (See page 30)

Will the tender offer be followed by a merger if all the Company shares are not
tendered in the offer?

   Yes. If we accept for payment and pay for at least a majority of the
Company's outstanding shares on a fully diluted basis, Merger Sub will be
merged with and into the Company. The Company will be the surviving corporation
and will become a wholly owned subsidiary of the Purchaser. In the merger, all
stockholders who did not tender their shares will receive $23.00 per share in
cash in exchange for their shares. (See page 21)

Can I exercise appraisal rights with respect to my Shares?

   There are no appraisal rights available in connection with the offer.
However, if the merger takes place, stockholders who have not sold their shares
in the offer will have appraisal rights under Delaware law. (See page 32)

If I decide not to tender, how will the offer affect my shares?

   If you don't tender your shares, your shares will be canceled in the merger
and you will receive the same amount of cash per share which you would have
received had you tendered your shares in the offer, unless you exercise
dissenters' rights under Delaware law (see page 32). Therefore, the only
difference to you between tendering your shares and not tendering your shares
is that you will be paid earlier if you tender your shares and you will not
have dissenters' rights. However, if the merger does not take place, the number
of stockholders and the number of shares of the Company that are still in the
hands of the public may be so small that there no longer will be an active
public trading market (or, possibly, any public trading market) for the
Company's common stock. In addition, the Company may cease making filings with
the Securities and Exchange Commission or otherwise cease being required to
comply with the Securities and Exchange Commission rules relating to publicly
held companies.

                                       3
<PAGE>


What is the market value of my shares as of a recent date?

   On June 13, 2000, the last trading day before the announcement that the
Merger Agreement was signed and that we would be commencing a tender offer, the
closing price of the Company common stock on the New York Stock Exchange was
$13.375 per share. During the twenty trading days immediately prior to June 13,
2000, the average closing price was $13.466 per share. On June 20, 2000, the
most recent practicable trading day before we commenced our tender offer, the
closing price was $22.625 per share. We advise you to obtain a recent quotation
for shares of the Company common stock in deciding whether to tender your
shares.

What are the U.S. federal income tax consequences of tendering shares?

   The receipt of cash for shares pursuant to the offer or the merger will be a
taxable transaction for United States federal income tax purposes and may also
be a taxable transaction under applicable state, local, foreign and other tax
laws. In general, a stockholder who sells shares pursuant to the offer or
receives cash in exchange for shares pursuant to the merger will recognize gain
or loss for United States federal income tax purposes equal to the difference,
if any, between the amount of cash received and the stockholder's adjusted tax
basis in the shares sold pursuant to the offer or exchanged for cash pursuant
to the merger. In general, capital gains recognized by an individual will be
subject to a maximum United States federal income tax rate of 20% if the shares
were held for more than one year, and if held for one year or less they will be
subject to tax at ordinary income tax rates. Because individual circumstances
may differ, you should consult your tax advisor to determine the particular tax
consequences to you. (See page 12)

To whom can I talk if I have questions about the offer?

   You can call Georgeson Shareholder Communications Inc., the information
agent, at (800) 223-2064 (toll free) or Morgan Stanley & Co. Incorporated, the
dealer manager, at (312) 706-4448. See the back cover of this offer to purchase
for information regarding the information agent and the dealer manager.

To: The Holders of Common Stock of Wynn's International, Inc.:

                                 INTRODUCTION

   WI Holding Inc. ("Merger Sub"), a Delaware corporation and a wholly owned
subsidiary of Parker-Hannifin Corporation, an Ohio corporation (the
"Purchaser"), hereby offers to purchase all the outstanding shares of common
stock, par value $0.01 per share, including the associated preferred share
purchase rights (the "Shares"), of Wynn's International, Inc., a Delaware
corporation (the "Company"), at a purchase price of $23.00 per Share, 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 collectively, and together with any amendments or
supplements hereto or thereto, constitute the "Offer").

   The Offer is being made pursuant to an Agreement and Plan of Merger, dated
as of June 13, 2000 (the "Merger Agreement"), among the Purchaser, Merger Sub
and the Company pursuant to which, following the consummation of the Offer and
the satisfaction or waiver of certain conditions, Merger Sub will be merged
with and into the Company (the "Merger"), with the Company continuing as the
surviving corporation (the "Surviving Corporation"). In the Merger, each
outstanding Share (other than Shares held by the Purchaser or any subsidiary
of the Purchaser or in the treasury of the Company, all of which will be
canceled with no payment being made with respect thereto, and other than
Shares ("Dissenting Shares"), if any, held by stockholders who perfect their
appraisal rights under the Delaware General Corporation Law (the "DGCL")),
will, by virtue of the Merger and without any action by the holder thereof, be
converted into the right to receive $23.00 in cash (the "Merger
Consideration"), payable to the holder thereof, without interest thereon, upon
the surrender of the certificate formerly representing such Share. The Merger
Agreement is more fully described in Section 11 below. Certain tax
consequences of the sale of Shares pursuant to the Offer and the Merger, as
the case may be, are described in Section 5 below.

   Simultaneously with the execution of the Merger Agreement, the Purchaser,
Merger Sub and James Carroll, the Chairman of the Board and Chief Executive
Officer of the Company, who beneficially owns 1,086,903 of the Shares (or 5.5%
on a fully diluted basis), entered into a Stockholder Tender Agreement, dated
June 13, 2000 (the "Tender Agreement"), pursuant to which Mr. Carroll agreed,
among other things, to tender his Shares pursuant to the Offer. See Section
11.

   Tendering stockholders will not be obligated to pay brokerage fees or
commissions or, except as set forth in Instruction 6 of the Letter of
Transmittal, stock transfer taxes on the purchase of Shares by Merger Sub
pursuant to the Offer.

   The Board of Directors of the Company has unanimously approved the Merger
Agreement and the transactions contemplated by the Merger Agreement, including
the Offer and the Merger; has determined that the terms of the Offer and the
Merger are fair to and in the best interests of the stockholders of the
Company; and unanimously recommends that the stockholders of the Company
accept the Offer and tender their shares pursuant to the Offer.

   J.P. Morgan, the Company's financial advisor, has delivered to the Board of
Directors of the Company a written opinion, dated June 13, 2000, to the effect
that, as of such date and subject to the assumptions and considerations
described in the opinion, the consideration to be paid to the Company's
stockholders and the holders of options to purchase Shares pursuant to the
Offer and the Merger is fair to such holders from a financial point of view. A
copy of that opinion is included with the Company's
Solicitation/Recommendation Statement on Schedule 14D-9 (the "Schedule 14D-
9"), which is being mailed to stockholders concurrently herewith. 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 J.P. Morgan.

   The Offer is conditioned upon, among other things, there being validly
tendered prior to the expiration of the Offer and not properly withdrawn a
number of Shares that represents at least a majority

                                       5
<PAGE>

of the total number of outstanding Shares on a fully diluted basis on the date
of purchase (the "Minimum Condition"). The Offer is also subject to certain
other terms and conditions as set forth in this Offer to Purchase. The Offer
will expire at 12:00 midnight, New York City time, on Thursday, July 20, 2000,
unless extended. See Sections 1, 13 and 14 below.

   The Company's Certificate of Incorporation and the DGCL require the
affirmative vote of holders of a majority of the outstanding Shares to approve
the Merger. As a result, if the Minimum Condition and the other conditions to
the Offer are satisfied and the Offer is consummated, Merger Sub will own a
sufficient number of Shares to ensure that the Merger will be approved. Under
the DGCL, if after consummation of the Offer, Merger Sub owns at least 90% of
the Shares then outstanding, Merger Sub will be able to cause the Merger to
occur without a vote of the Company's stockholders. If, however, after
consummation of the Offer, Merger Sub owns less than 90% of then outstanding
Shares, a vote of the Company's stockholders will be required under the DGCL
to approve the Merger, and a significantly longer period of time will be
required to effect the Merger. See Section 11.

   No appraisal rights are available in connection with the Offer.
Stockholders may, however, have appraisal rights in connection with the
Merger, regardless of whether the Merger is consummated with or without a vote
of the Company's stockholders. See Section 11.

   The Company has informed Merger Sub that, as of June 20, 2000, there were
18,688,809 Shares issued and outstanding, and 962,826 Shares reserved for
issuance pursuant to stock-based plans and awards outstanding thereunder on
June 20, 2000. Based upon the foregoing and assuming that no other Shares are
otherwise issued after June 20, 2000, the Minimum Condition will be satisfied
if at least 9,825,818 Shares are validly tendered and not withdrawn prior to
the Expiration Date (as defined in Section 1). The actual number of Shares
required to be tendered to satisfy the Minimum Condition will depend upon the
actual number of Shares outstanding on a fully diluted basis on the date that
Merger Sub accepts Shares for payment pursuant to the Offer. If the Minimum
Condition is satisfied, and Merger Sub accepts for payment Shares tendered
pursuant to the Offer, the Purchaser will be able to elect a majority of the
members of the Company's Board of Directors and to effect the Merger without
the affirmative vote of any other stockholder of the Company. See Section 11.

   This Offer to Purchase and the related Letter of Transmittal contain
important information and should be read carefully before any decision is made
with respect to the Offer.

                                   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), Merger Sub will, as soon as practicable after the
Expiration Date, accept for payment and thereby purchase all Shares validly
tendered on or prior to such Expiration Date and not withdrawn in accordance
with the procedures set forth in Section 4. The Offer shall remain open until
12:00 midnight, New York City time, on Thursday, July 20, 2000 (the
"Expiration Date"), unless and until Merger Sub shall have extended the period
of time for which the Offer is open, in which event the term "Expiration Date"
shall mean the time and date at which the Offer, as so extended by Merger Sub,
shall expire. During any such extension, all Shares previously tendered and
not withdrawn will remain subject to the Offer and subject to the right of a
tendering stockholder to withdraw such stockholder's Shares. See Section 4.

   In the Merger Agreement, the Purchaser and Merger Sub agreed that Merger
Sub will not (a) decrease the price per Share payable in the Offer or change
the form of consideration payable in the Offer, (b) decrease the number of
Shares sought, (c) amend or waive the Minimum Condition or (d) impose
additional conditions to the Offer or amend any other term of the Offer in a
manner adverse to the holders of Shares. However, if on the initial Expiration
Date all conditions to the Offer shall not have been satisfied or waived,
Merger Sub may extend

                                       6
<PAGE>

the Expiration Date for such additional period or periods as it may determine
to permit such conditions to be satisfied but not beyond Tuesday, August 15,
2000, except with the written consent of the Company. In addition, if at any
scheduled Expiration Date, the condition to the Offer relating to required
regulatory approvals is not satisfied, Merger Sub will extend the Offer from
time to time (each such extension not to exceed ten business days after the
previously scheduled expiration date, unless the parties otherwise agree;
provided, that each party shall have the right to terminate the Merger
Agreement if the Offer is not completed by December 15, 2000), subject to the
right of the Purchaser, Merger Sub or the Company to terminate the Merger
Agreement pursuant to its terms.

   If by 12:00 midnight, New York City time, on Thursday, July 20, 2000 (or
any date or time then set as the Expiration Date), any or all of the
conditions to the Offer (except for the condition related to required
regulatory approvals) have not been satisfied or waived, the Purchaser
reserves the right to (but shall not be obligated except as described in this
Section 1), subject to the terms and conditions contained in the Merger
Agreement and to the applicable rules and regulations of the Securities and
Exchange Commission (the "SEC"), (i) terminate the Offer and not accept for
payment or pay for any Shares and return all tendered Shares to tendering
stockholders, (ii) elect to provide a Subsequent Offering Period (as defined
below) for the Offer, (iii) waive all the unsatisfied conditions except for
the Minimum Condition and accept for payment and pay for all Shares validly
tendered prior to the Expiration Date and not theretofore withdrawn, (iv)
extend the Offer and, subject to the right of stockholders to withdraw Shares
until the Expiration Date, retain the Shares that have been tendered during
the period or periods for which the Offer is extended or (v) amend the Offer.

   Any extension, waiver, amendment or termination of the Offer will be
followed as promptly as practicable by public announcement thereof. In the
case of an extension, Rule 14e-1(d) under the Securities Exchange Act of 1934,
as amended (the "Exchange Act") requires that the announcement be issued no
later than 9:00 a.m., New York City time, on the next business day after the
previously scheduled Expiration Date in accordance with the public
announcement requirements of Rule 14d-4(d) under the Exchange Act. Subject to
applicable law (including Rules 14d-4(d) and 14d-6(c) under the Exchange Act,
which require that any material change in the information published, sent or
given to stockholders in connection with the Offer be promptly disseminated to
stockholders in a manner reasonably designed to inform stockholders of such
change) and without limiting the manner in which Merger Sub may choose to make
any public announcement, Merger Sub will not have any obligation to publish,
advertise or otherwise communicate any such public announcement other than by
making a release to the Dow Jones News Service.

   If Merger Sub extends the Offer or if Merger Sub is delayed in its
acceptance for payment of or payment (whether before or after our acceptance
for payment of Shares) for Shares or Merger Sub is unable to pay for Shares
pursuant to the Offer for any reason, then, without prejudice to its rights
under the Offer, the Depositary may retain tendered Shares on behalf of Merger
Sub, and such Shares may not be withdrawn except to the extent tendering
stockholders are entitled to withdrawal rights as described in Section 4.
However, Merger Sub's ability to delay the payment for Shares that it has
accepted for payment is limited by Rule 14e-1(c) under the Exchange Act, which
requires that a bidder pay the consideration offered or return the securities
deposited by or on behalf of holders of securities promptly after the
termination or withdrawal of such bidder's offer, and by the terms of the
Merger Agreement, which require that Merger Sub pay for Shares accepted for
payment as soon as reasonably practicable after the Expiration Date.

   If Merger Sub makes a material change in the terms of the Offer or the
information concerning the Offer or waives a material condition of the Offer,
Merger Sub will disseminate additional tender offer materials and extend the
Offer to the extent required by Rules 14d-4(d), 14d-6(c) and 14e-1 under the
Exchange Act. The minimum period during which an offer must remain open
following material changes in the terms of such offer or information
concerning such offer, other than a change in price or a change in the
percentage of securities sought, will depend upon the facts and circumstances
then existing, including the relative materiality of the changed terms or
information. In the SEC's view, 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 material changes are made with respect to
information that approaches the significance of price and the percentage of
securities sought, a

                                       7
<PAGE>

minimum of ten business days may be required to allow for adequate
dissemination and investor response. With respect to a change in price, a
minimum ten-business-day period from the date of the change is generally
required to allow for adequate dissemination to stockholders.

   Pursuant to Rule 14d-11 under the Exchange Act, Merger Sub may, subject to
certain conditions, provide a subsequent offering period of from three
business days to 20 business days in length following the expiration of the
Offer on the Expiration Date ("Subsequent Offering Period"). A Subsequent
Offering Period would be an additional period of time, following the
expiration of the Offer and the purchase of Shares in the Offer during which
stockholders may tender shares not tendered in the Offer. A Subsequent
Offering Period, if one is included, is not an extension of the Offer, which
already will have been completed.

   During a Subsequent Offering Period, tendering stockholders will not have
withdrawal rights and Merger Sub will promptly purchase and pay for any Shares
tendered at the same price paid in the Offer. Rule 14d-11 provides that Merger
Sub may provide a Subsequent Offering Period so long as, among other things,
(i) the initial 20 business day period of the Offer has expired, (ii) Merger
Sub offers the same form and amount of consideration for Shares in the
Subsequent Offering Period as in the initial Offer, (iii) Merger Sub accepts
and promptly pays for all Shares tendered during the Offer prior to its
expiration, (iv) Merger Sub announces the results of the Offer, including the
approximate number and percentage of Shares deposited in the Offer, no later
than 9:00 a.m. Eastern time on the next business day after the Expiration Date
and immediately begins the Subsequent Offering Period and (v) Merger Sub
immediately accepts and promptly pays for Shares as they are tendered during
the Subsequent Offering Period. Merger Sub will be able to provide a
Subsequent Offering Period, if it satisfies the conditions above, after July
20, 2000.

   Merger Sub does not currently intend to provide a Subsequent Offering
Period for the Offer, although Merger Sub reserves the right to do so in its
sole discretion. Pursuant to Rule 14d-7 under the Exchange Act, no withdrawal
rights will apply to Shares tendered during a Subsequent Offering Period.

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

2. Acceptance for Payment and Payment

   Upon the terms and subject to the conditions of the Offer (including, if
the Offer is extended or amended, the terms and conditions of the Offer as so
extended or amended), Merger Sub will purchase, by accepting for payment, and
will pay for, all Shares validly tendered and not properly withdrawn (in
accordance with Section 4) prior to the Expiration Date promptly after the
later to occur of (i) the Expiration Date and (ii) the satisfaction or waiver
of the conditions to the Offer. See Sections 1 and 13. In addition, subject to
applicable rules of the SEC, Merger Sub expressly reserves the right to delay
acceptance for payment of, or payment for, Shares pending receipt of any
regulatory or governmental approvals specified in Section 14.

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

                                       8
<PAGE>

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

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

   Under no circumstances will interest on the purchase price for Shares be
paid by Merger Sub.

   If any tendered Shares are not purchased pursuant to the Offer for any
reason, or if Share Certificates are submitted representing more Shares than
are tendered, Share Certificates representing unpurchased or untendered Shares
will be returned, 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, such Shares will be credited to an account maintained within the
Book-Entry Transfer Facility), as promptly as practicable following the
expiration, termination or withdrawal of the Offer.

   If, prior to the Expiration Date, Merger Sub increases the consideration
offered to holders of Shares pursuant to the Offer, such increased
consideration will be paid to all holders of Shares that are purchased
pursuant to the Offer, whether or not such Shares were tendered prior to such
increase in consideration.

   Merger Sub reserves the right, subject to the provisions of the Merger
Agreement, to assign, in whole or from time to time in part, to one or more of
the Purchaser's affiliates the right to purchase all or any portion of the
Shares tendered pursuant to the Offer, but no such assignment will relieve
Merger Sub of its obligations under the Offer or prejudice the rights of
tendering stockholders to receive payment for Shares validly tendered and
accepted for payment pursuant to the Offer.

3. Procedures for Accepting the Offer and Tendering Shares

   Valid Tender of Shares. Except as set forth below, in order for Shares to
be validly tendered pursuant to the Offer, the Letter of Transmittal (or a
facsimile thereof), properly completed and duly executed, together with any
required signature guarantees or an Agent's Message in connection with a book-
entry delivery of Shares and any other documents required by the Letter of
Transmittal must be received by the Depositary at one of its addresses set
forth on the back cover of this Offer to Purchase on or prior to the
Expiration Date and either (i) Share Certificates representing tendered Shares
must be received by the Depositary or tendered pursuant to the procedure for
book-entry transfer set forth below and Book-Entry Confirmation must be
received by the Depositary, in each case on or prior to the Expiration Date or
(ii) the tendering stockholder must comply with the guaranteed delivery
procedures set forth below.

   The method of delivery of Share Certificates, the Letter of Transmittal and
all other required documents is at the option and sole risk of the tendering
stockholder, and delivery will be deemed made only when actually received by
the Depositary. If delivery is by mail, registered mail with return receipt
requested, properly insured, is recommended. In all cases, sufficient time
should be allowed to ensure timely delivery.

   Book-Entry Transfer. The Depositary will make a request to establish an
account with respect to the Shares at the Book-Entry Transfer Facility for
purposes of the Offer within two business days after the date of this Offer

                                       9
<PAGE>

to Purchase. Any financial institution that is a participant in the system of
the Book-Entry Transfer Facility 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 the Book-Entry Transfer Facility, the Letter of
Transmittal (or facsimile thereof), properly completed and duly executed, with
any required signature guarantees, or an Agent's Message in connection with a
book-entry transfer, 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 on or prior to the
Expiration Date, or in compliance with the guaranteed delivery procedure set
forth below.

   Delivery of documents to the Book-Entry Transfer Facility in accordance
with the Book-Entry Transfer Facility's procedures does not constitute
delivery to the Depositary.

   Signature Guarantees. Signatures on all Letters of Transmittal must be
guaranteed by a firm that is a bank, broker, dealer, credit union, savings
association or other entity that is a member in good standing of the
Securities Transfer Agents Medallion Program (an "Eligible Institution"),
unless the Shares tendered thereby are tendered (i) by a registered holder of
Shares who has not completed either the box labeled "Special Payment
Instructions" or the box labeled "Special Delivery Instructions" on the Letter
of Transmittal or (ii) for the account of an Eligible Institution. See
Instruction 1 of the Letter of Transmittal.

   If the Share Certificates are registered in the name of a person other than
the signer of the Letter of Transmittal, or if payment is to be made to, or
Share Certificates for Shares not tendered or not accepted for purchase are to
be issued or returned to, a person other than the registered holder, then the
tendered Share Certificates must be endorsed or accompanied by appropriate
stock powers, signed exactly as the name or names of the registered holder or
holders appear on the Share Certificates, with the signatures on the Share
Certificates or stock powers guaranteed by an Eligible Institution as provided
in the Letter of Transmittal. See Instructions 1 and 5 of the Letter of
Transmittal.

   If the Share Certificates are forwarded separately to the Depositary, a
properly completed and duly executed Letter of Transmittal (or facsimile
thereof) must accompany each such delivery.

   Guaranteed Delivery. If a stockholder desires to tender Shares pursuant to
the Offer and such stockholder's Share Certificates are not immediately
available or time will not permit all required documents to reach the
Depositary on or prior to the Expiration Date or the procedures for book-entry
transfer cannot be completed on a timely basis, such Shares may nevertheless
be tendered if all of the following guaranteed delivery procedures are duly
complied with:

     (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 made available by Merger Sub, is
  received by the Depositary, as provided below, on or prior to the
  Expiration Date; and

     (iii) the Share Certificates (or a Book-Entry Confirmation) representing
  all tendered Shares, in proper form for transfer together with a properly
  completed and duly executed Letter of Transmittal (or facsimile thereof),
  with any required signature guarantees (or, in the case of a book-entry
  transfer, an Agent's Message) and any other documents required by the
  Letter of Transmittal are received by the Depositary within three New York
  Stock Exchange ("NYSE") trading days after the date of execution of such
  Notice of Guaranteed Delivery. A NYSE trading day is any day on which the
  NYSE is open for business.

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

                                      10
<PAGE>

   Notwithstanding any other provision hereof, payment for Shares accepted for
payment pursuant to the Offer will in all cases be made only after timely
receipt by the Depositary of Share Certificates for, or of Book-Entry
Confirmation with respect to, such Shares, a properly completed and duly
executed Letter of Transmittal (or facsimile thereof), together with any
required signature guarantees (or, in the case of a book-entry transfer, an
Agent's Message) and any other documents required by the appropriate Letter of
Transmittal. Accordingly, payment might not be made to all tendering
stockholders at the same time, and will depend upon when Share Certificates
are received by the Depositary or Book-Entry Confirmations of such Shares are
received into the Depositary's account at the Book-Entry Transfer Facility.

   Backup Federal Income Tax Withholding. Under the backup federal income tax
withholding laws applicable to certain stockholders (other than certain exempt
stockholders, including, among others, all corporations and certain foreign
individuals), the Depositary may be required to withhold 31% of the amount of
gross proceeds payable to such stockholders pursuant to the Offer or the
Merger. To prevent backup federal income tax withholding, each such
stockholder must provide the Depositary with such stockholder's correct
taxpayer identification number and certify that such stockholder is not
subject to backup federal income tax withholding by completing the Substitute
Form W-9 included in the Letter of Transmittal. See Instruction 9 of the
Letter of Transmittal.

   Appointment as Proxy. By executing the Letter of Transmittal, a tendering
stockholder irrevocably appoints designees of Merger Sub, and each of them, as
such stockholder's agents, 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 the Shares tendered
by such stockholder and accepted for payment by Merger Sub and with respect to
any and all other Shares and other securities or rights issued or issuable in
respect of such tendered Shares on or after the date of this Offer to
Purchase. All such powers of attorney and proxies shall be considered
irrevocable and coupled with an interest in the tendered Shares. Such
appointment will be effective upon the acceptance for payment of such Shares
by Merger Sub in accordance with the terms of the Offer. Upon such acceptance
for payment, all other powers of attorney and proxies given by such
stockholder with respect to such Shares and such other securities or rights
prior to such payment will be revoked, without further action, and no
subsequent powers of attorney and proxies may be given by such stockholder
(and, if given, will not be deemed effective). The designees of Merger Sub
will, with respect to the Shares and such other securities and rights for
which such appointment is effective, be empowered to exercise all voting and
other rights of such stockholder as they in their sole discretion may deem
proper at any annual or special meeting of the Company's stockholders, or any
adjournment or postponement thereof, or by consent in lieu of any such meeting
or otherwise. In order for Shares to be deemed validly tendered, immediately
upon the acceptance for payment of such Shares, Merger Sub or its designee
must be able to exercise full voting rights with respect to such Shares and
other securities, including voting at any meeting of stockholders.

   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 will be determined by Merger Sub, in its sole
discretion, whose determination shall be final and binding on all parties.
Merger Sub reserves the absolute right to reject any or all tenders determined
by it not to be in proper form or the acceptance of or payment for which may,
in the opinion of Merger Sub's counsel, be unlawful. Merger Sub also reserves
the absolute right to waive any of the conditions of the Offer (other than the
Minimum Condition, which may not be waived without the consent of the Company)
or any defect or irregularity in any tender of Shares of any particular
stockholder whether or not similar defects or irregularities are waived in the
case of other stockholders.

   Merger Sub's interpretation of the terms and conditions of the Offer will
be final and binding. No tender of Shares will be deemed to have been validly
made until all defects and irregularities with respect to such tender have
been cured or waived by Merger Sub. None of the Purchaser, Merger Sub or any
of their respective affiliates or assigns, the Depositary, the Information
Agent or any other person or entity will be under any duty to give any
notification of any defects or irregularities in tenders or incur any
liability for failure to give any such notification.

                                      11
<PAGE>

   Merger Sub's acceptance for payment of Shares tendered pursuant to any of
the procedures described above will constitute a binding agreement between the
tendering stockholder and Merger Sub upon the terms and subject to the
conditions of the Offer.

4. Withdrawal Rights

   Except as otherwise provided in this Section 4, tenders of Shares made
pursuant to the Offer are irrevocable. Shares tendered pursuant to the Offer
may be withdrawn at any time on or prior to the Expiration Date and, unless
theretofore accepted for payment as provided herein, may also be withdrawn at
any time after Sunday, August 20, 2000.

   If, for any reason whatsoever, acceptance for payment of any Shares
tendered pursuant to the Offer is delayed, or Merger Sub is unable to accept
for payment or pay for Shares tendered pursuant to the Offer, then, without
prejudice to Merger Sub's rights set forth herein, the Depositary may,
nevertheless, on behalf of Merger Sub, retain tendered Shares and such Shares
may not be withdrawn except to the extent that the tendering stockholder is
entitled to exercise and duly exercises withdrawal rights as described in this
Section 4. Any such delay will be by an extension of the Offer to the extent
required by law.

   In order for a withdrawal to be effective, a written or facsimile
transmission notice of withdrawal must be timely received by the Depositary at
one of its addresses set forth on the back cover of this Offer to Purchase.
Any such notice of withdrawal must specify the name of the person who tendered
the Shares to be withdrawn, the number of Shares to be withdrawn, and (if
Share Certificates have been tendered) the name of the registered holder of
the Shares as set forth in the Share Certificate, if different from that of
the person who tendered such Shares. If Share Certificates have been delivered
or otherwise identified to the Depositary, then prior to the physical release
of such certificates, the tendering stockholder must submit 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, except in the case of Shares tendered for the account of an
Eligible Institution. If Shares have been tendered pursuant to the procedures
for book-entry transfer set forth in Section 3, 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, in which case a notice of withdrawal
will be effective if delivered to the Depositary by any method of delivery
described in the first sentence of this paragraph. Withdrawals of Shares may
not be rescinded. Any Shares properly withdrawn will be deemed not validly
tendered for purposes of the Offer, but may be tendered at any subsequent time
prior to the Expiration Date by following any of the procedures described in
Section 3.

   All questions as to the form and validity (including time of receipt) of
notices of withdrawal will be determined by Merger Sub, in its sole
discretion, whose determination shall be final and binding. None of the
Purchaser, Merger Sub or any of their respective affiliates or assigns, the
Depositary, the Information Agent, the Dealer Manager or any other person or
entity will be under any duty to give any notification of any defects or
irregularities in any notice of withdrawal or incur any liability for failure
to give any such notification.

   In the event Merger Sub provides a Subsequent Offering Period following the
Offer, no withdrawal rights will apply to Shares tendered during such
Subsequent Offering Period or to Shares tendered in the Offer and accepted for
payment.

5. Certain U.S. Federal Income Tax Consequences

   The following discussion is a summary of certain U.S. federal income tax
consequences of the Offer or the Merger to a Company stockholder holding
Shares as a capital asset within the meaning of Section 1221 of the Internal
Revenue Code of 1986, as amended (the "Code").

   This discussion does not address all aspects of federal taxation that may
be relevant to particular holders of Shares in light of their personal
circumstances or to holders of Shares subject to special treatment under the

                                      12
<PAGE>

Code, including, without limitation, financial institutions or trusts; tax-
exempt entities; insurance companies; traders that mark to market; dealers in
securities or foreign currencies; stockholders who received their Shares
through an exercise of employee stock options or otherwise as compensation;
stockholders who are foreign corporations, foreign partnerships, or other
foreign entities, or individuals who are not citizens or residents of the
U.S.; and stockholders who hold Shares as part of a hedge, straddle or
conversion transaction.

   The receipt of cash in exchange for Shares pursuant to the Offer or the
Merger will be a taxable transaction for federal income tax purposes. Each
selling or exchanging stockholder will generally recognize capital gain or
loss equal to the difference between the amount of cash received and such
stockholder's adjusted tax basis for the Shares tendered in exchange therefor.
Capital gain or loss will be determined separately for each block of Shares
(i.e., Shares acquired at the same time and same price) exchanged pursuant to
the Offer or the Merger. Capital gain or loss will be long-term if, as of the
date of sale or exchange, the Shares were held for more than one year or will
be short-term if, as of such date, the Shares were held for one year or less.
In general, long-term capital gains recognized by an individual will be
subject to a maximum U.S. federal income tax rate of 20%, and short-term
capital gains will be subject to tax at ordinary income tax rates.

   Unless you comply with certain reporting and/or certification procedures or
are an exempt recipient under applicable provisions of the Code and Treasury
regulations, cash payments in exchange for your Shares in the Offer or the
Merger may be subject to "backup withholding" at a rate of 31% for federal
income tax purposes. Any amounts withheld under the backup withholding rules
may be allowed as a refund or credit against the holder's federal income tax
liability, provided the required information is provided to the Internal
Revenue Service.

   The foregoing summary is for general information purposes only and is based
on United States federal income tax law now in effect, which is subject to
change, possibly retroactively. Stockholders are strongly urged to consult
their tax advisors with respect to the specific tax consequences to them of
the Offer and the Merger, including federal, state, local, foreign and other
tax consequences.

6. Price Range of the Shares

   According to the Company's Annual Report on Form 10-K for the fiscal year
ended December 31, 1999 (the "Form 10-K"), the Shares are traded on the NYSE
under the symbol "WN." The following table sets forth, for the periods
indicated, the reported high and low sale prices for the Shares on the NYSE as
reported in the Form 10-K with respect to calendar periods occurring in 1998
and 1999, and as reported thereafter by published financial sources with
respect to the first two calendar quarters of 2000.

   On June 13, 2000, the last full day of trading prior to the announcement of
the execution of the Merger Agreement, according to published sources, the
reported closing price on the NYSE for the Shares was $13 3/8 per Share. On
June 20, 2000, the most recent practicable trading day prior to the
commencement of the Offer, according to published sources, the reported
closing price on the NYSE for the Shares was $22 5/8 per Share.

7. Possible Effects of the Offer on the Market for the Shares; NYSE Listing;
   Exchange Act Registration; Margin Regulations

   Possible Effects of the Offer on the Market for the Shares. The purchase of
Shares pursuant to the Offer will reduce the number of Shares that might
otherwise trade publicly and could adversely affect the liquidity and market
value of the remaining Shares held by the public. The purchase of Shares
pursuant to the Offer can also be expected to reduce the number of holders of
Shares. Merger Sub cannot predict whether the reduction in the number of
Shares that might otherwise trade publicly would have an adverse or beneficial
effect on the market price for or marketability of the Shares or whether it
would cause future market prices to be greater or less than the Offer price
therefor.

   NYSE Listing. The Purchaser currently intends to cause the Company to
delist the Shares from the NYSE as soon after consummation of the Offer and
the Merger as reasonably practicable. Depending upon the number of Shares
purchased pursuant to the Offer, the Shares may no longer meet the standards
for continued listing on the NYSE after consummation of the Offer. According
to the NYSE's published guidelines, the Shares would not be eligible to be
included for continued listing if the number of publicly held Shares and the
average monthly trading volume fall below certain levels, or the number of
publicly held Shares falls below 600,000, or the aggregate market value of the
Shares falls below $15,000,000. If these standards are not met, the Shares
would no longer be admitted to listing on the NYSE. Shares held directly or
indirectly by an officer or director of the Company or by a beneficial owner
of more than 10% of the Shares will ordinarily not be considered as being
publicly held for purposes of these standards.

   Merger Sub has been advised by the Company that as of June 20, 2000, there
were approximately 866 holders of record of the Shares. The Company has
advised Merger Sub that it believes that the number of beneficial owners of
the Shares as of June 20, 2000 is approximately 6,500.

   Exchange Act Registration. The Shares are currently registered under the
Exchange Act. The purchase of the Shares pursuant to the Offer may result in
the Shares becoming eligible for termination of registration under the
Exchange Act. It is the intention of Merger Sub to cause the Company to make
an application for termination of registration of the Shares as soon as
possible after successful completion of the Offer if the Shares are then
eligible for such termination. Registration of the Shares may be terminated
upon application by the Company to the SEC if the Shares are not listed on a
national securities exchange and there are fewer than 300 record holders of
Shares. Termination of registration of the Shares under the Exchange Act would
substantially reduce the information required to be furnished by the Company
to its stockholders and the SEC and would make certain provisions of the
Exchange Act, such as the short-swing profit recovery provisions of Section
16(b) and the requirements of furnishing a proxy statement in connection with
stockholders' meetings pursuant to Section 14(a) or 14(c) and the related
requirement of an annual report, no longer applicable to the Company. If the
Shares are no longer registered under the Exchange Act, the requirements of
Rule 13e-3 under the Exchange Act with respect to "going private" transactions
would no longer be applicable to the Company. Furthermore, the ability of
"affiliates" of the Company and persons holding "restricted securities" of the
Company to dispose of such securities pursuant to Rule 144 promulgated under
the Securities Act of 1933 may be impaired or, with respect to certain
persons, eliminated. If registration of the Shares under the Exchange Act were
terminated, the Shares would no longer be "margin securities" or eligible for
NYSE listing or quotation.

   If registration of the Shares is not terminated prior to the Merger, then
following the consummation of the Merger, the Shares will no longer be
eligible for NYSE listing and the registration of the Shares under the
Exchange Act will be terminated.

                                      14

   Margin Regulations. The Shares are currently "margin securities" under the
regulations of the Board of Governors of the Federal Reserve System (the
"Federal Reserve Board"), which have the effect, among other things, of
allowing brokers to extend credit on the collateral of such Shares for the
purpose of buying, carrying or trading in securities ("Purpose Loans").
Depending upon factors such as the number of record holders of the Shares and
the number and market value of publicly held Shares, following the purchase of
Shares pursuant to the Offer, the Shares might no longer constitute "margin
securities" for purposes of the Federal Reserve Board's margin regulations
and, therefore, could no longer be used as collateral for Purpose Loans made
by brokers. In addition, as stated above, if registration of the Shares under
the Exchange Act were terminated, the Shares would no longer constitute
"margin securities."

Net Income...................................   36.9   46.9   55.7   65.8   77.7
</TABLE>

   The Company has advised the Purchaser that it does not as a matter of
course make public any projections as to future performance or earnings, and
the projections set forth above are included in this Offer to Purchase only
because this information was provided to the Purchaser. The projections were
not prepared with a view to public disclosure or compliance with the published
guidelines of the SEC or the guidelines established by the American Institute
of Certified Public Accountants regarding projections or forecasts. The
projections do not purport to present operations in accordance with generally
accepted accounting principles, and the Company's independent auditors have
not examined or compiled the projections and accordingly assume no
responsibility for them. The Company has advised the Purchaser that its
internal financial forecasts (upon which the projections provided to the
Purchaser were based in part) are, in general, prepared solely for internal
use and capital budgeting and other management decisions and are subjective in
many respects and thus susceptible to interpretations and periodic revision
based on actual experience and business developments. The projections also
reflect numerous assumptions made by management of the Company with respect to
industry performance, forecasting on general business, economic, market and
financial conditions and other matters, including effective tax rates
consistent with historical levels for the Company and expected debt payments,
all of which are difficult to predict, many of which are beyond the Company's
control, and none of which were subject to approval by the Purchaser.
Accordingly, there can be no assurance that the assumptions made in preparing
the projections will prove accurate. It is expected that there will be
differences between actual and projected results, and actual results may be
materially greater or less than those contained in the projections. The
inclusion of the projections herein

                                      15
<PAGE>

should not be regarded as an indication that any of the Purchaser, Merger Sub,
the Company or their respective affiliates or representatives considered or
consider the projections to be a reliable prediction of future events, and the
projections should not be relied upon as such. None of the Purchaser, Merger
Sub, the Company or any of their respective affiliates or representatives has
made or makes any representation to any person regarding the ultimate
performance of the Company compared to the information contained in the
projections to reflect circumstances existing after the date when made or to
reflect the occurrence of future events even in the event that any or all of
the assumptions underlying the projections are shown to be in error.

exploring a business combination. On February 7, 2000, the Company and the
Purchaser entered into a confidentiality agreement.


                                      17

   On February 18, 2000, representatives of the Company and the Purchaser
attended a meeting in Irvine, California at which representatives of the
Company discussed in general the Company's business, prospects, technology,
products and financial condition. Mr. Carroll and Seymour A. Schlosser, the
Vice President--Finance and Chief Financial Officer of the Company, attended
the meeting on behalf of the Company and Mr. Vande Steeg, Michael J. Hiemstra,
the Purchaser's Vice President--Finance and Administration and Chief Financial
Officer, and James Miserendino, the Vice President and Controller of the
Purchaser's Seal Group, attended the meeting on behalf of the Purchaser. As a
result of the February 18 meeting, the parties decided to schedule a meeting
for mid-March, at which time the three financial officers present at the
February 18 meeting would discuss in greater detail the historical results,
current performance and future forecasts of the Company.

   On March 16, 2000, Mr. Schlosser, on behalf of the Company, and Messrs.
Hiemstra and Miserendino, on behalf of the Purchaser, attended a meeting in
Irvine, California. At that meeting, representatives of the Purchaser and the
Company engaged in preliminary discussions about the historical results,
current performance and future forecasts of the Company and potential values
and valuation processes. At that meeting, the parties agreed to meet again in
April with the chief executive officers of each company.

   During late March and early April, representatives of the Purchaser and the
Company continued their discussions regarding a possible business combination
involving the Purchaser and the Company, including more extensive discussions
regarding the Purchaser's valuation of the Company. The Purchaser suggested a
preliminary valuation of $22.00 per share.

   On April 6, 2000, the Purchaser's Board of Directors held a regularly
scheduled meeting at which Purchaser's management updated the Board regarding
the status of discussions with the Company.

   On April 12, 2000, Messrs. Collins, Vande Steeg, Hiemstra and Miserendino,
on behalf of the Purchaser, and Messrs. Carroll, Schlosser and John Halenda,
the President of Wynn's-Precision, Inc., on behalf of the Company, met in
Nashville, Tennessee. At that meeting, the Company's representatives made
comprehensive presentations regarding the Company's business, prospects,
technology, products and financial condition.

   On April 20, 2000, Mr. Collins telephoned Mr. Carroll to discuss the
Purchaser's valuation of the Company. Mr. Collins indicated that Purchaser had
raised its preliminary valuation to $24.00 per share depending upon the
results of Purchaser's valuation work related to the Company's Specialty
Chemicals Division.

   On April 24, 2000, Messrs. Collins and Carroll met for dinner in Nashville,
Tennessee to further discuss the Purchaser's intentions with respect to a
business combination involving the Company.

   On April 26, 2000, the Company's Board of Directors held a telephonic

of the Purchaser's verbal expression of interest in pursuing a business
combination with the Company. The Company's Board authorized the Company's
senior management to pursue discussions with the Purchaser and to commence the
due diligence process with Purchaser. After the April 26 meeting of the
Company's Board, the Company engaged J.P. Morgan to act as its financial
advisor and the parties began to schedule due diligence meetings.

   On May 4, 2000, the Purchaser engaged Morgan Stanley & Co. Incorporated
("Morgan Stanley") to act as its financial advisor.

to continue discussions with the Purchaser.

   On May 11 through May 19, 2000, representatives of the Purchaser and Morgan
Stanley engaged in extensive due diligence meetings with representatives of
the Company and J.P. Morgan regarding, among other things, environmental,
financial and litigation matters. On May 19, 2000, the Purchaser provided the
Company and the Company's legal counsel with the initial draft of the Merger
Agreement.

<PAGE>

   On May 22, 2000, members of the Purchaser's due diligence team and
representatives of Morgan Stanley met with members of the Purchaser's
management to discuss the status of the due diligence performed by the
Purchaser. Based on these discussions, Mr. Collins met with Mr. Carroll on May
22, 2000 regarding the Purchaser's preliminary offer price per share. Mr.
Collins advised Mr. Carroll that based on the results of its valuation work
related to the Company's Specialty Chemicals Division, the Purchaser would be
willing to proceed at a price of $22.00 per share. Thereafter, J.P. Morgan, on
behalf of the Company, and Morgan Stanley, on behalf of the Purchaser, engaged
in additional discussions concerning the proposed offer price per share and
related matters.

   From June 3 through June 5, 2000, the Purchaser engaged in additional due
diligence activities with respect to the Company and its facilities. On June
5, 2000, members of the Purchaser's management team met to discuss the results
of the additional due diligence activities. Thereafter, management of the
Purchaser and the Company continued discussions regarding the price per share,
with the representatives agreeing to request that their Boards of Directors
consider a price per Share of $23.00 subject to negotiation of the definitive
merger agreement and the receipt of further input and advice from the parties'
respective financial advisors.

   Beginning on June 6, 2000 and continuing through June 13, 2000, the parties
continued to discuss the economic terms of the proposed transaction,
negotiated the terms of the Merger Agreement and the Purchaser finalized its
due diligence review of the Company.

   The Purchaser's Board of Directors met on June 8, 2000. At that meeting,
the Purchaser's directors were advised of, among other things, the status of
the negotiations regarding the Merger Agreement, including the terms of the
proposed Offer.

   The Company's Board of Directors met on June 9, 2000. At that meeting, the
Company's directors were advised of, among other things, the status of the
negotiations regarding the Merger Agreement, including the terms of the
proposed Offer. J.P. Morgan also provided a preliminary analysis supporting
its draft fairness opinion.

   On June 13, 2000, the Purchaser's Board of Directors met and unanimously
approved the Offer, the Merger Agreement, the Merger and the transactions
contemplated thereby and authorized its officers to execute the Merger
Agreement.

   On June 13, 2000, the Company's Board of Directors met and unanimously
approved the Offer, the Merger Agreement, the Merger and the transactions

meeting.

The Merger Agreement

   The following is a summary of the material terms of the Merger Agreement
and is qualified in its entirety by reference to the complete text of the
Merger Agreement, a copy of which is filed with the SEC as Exhibit (d)(2) to
the Schedule TO and is incorporated herein by reference. The Merger Agreement
should be read in its entirety for a more complete description of the matters
summarized below. Defined terms used below and not defined herein have the
respective meanings assigned to those terms in the Merger Agreement.

   The Offer. The Merger Agreement contemplates the commencement of the Offer
and prescribes conditions to consummation of the Offer. The Merger Agreement
provides that, without the prior written consent of the Company, Merger Sub
may not and the Purchaser shall cause Merger Sub not to (i) decrease the
amount offered per Share or change the form of consideration payable in the
Offer, (ii) decrease the number of Shares sought to be purchased in the Offer,
(iii) amend or waive the Minimum Condition, or (iv) impose additional
conditions to the Offer or amend any other term of the Offer in any manner
adverse to the holders of Shares. If on the initial Expiration Date, which
shall be 20 business days following commencement of the Offer, all conditions
to the Offer shall not have been satisfied or waived, Merger Sub may extend
the Expiration Date for an additional period or periods as it may determine to
the extent necessary to permit such conditions to be satisfied; provided,
however, that the Expiration Date may not be extended beyond Tuesday, August
15, 2000, except with the written consent of the Company. In addition, the
Merger Agreement provides that the Purchaser may cause Merger Sub, without the
consent of the Company, to elect to provide a subsequent offering period for
the Offer in accordance with Rule 14d-11 of the Exchange Act. Merger Sub will,
on the terms and subject to the prior satisfaction or waiver of the conditions
of the Offer, accept for payment and purchase, as soon as permitted under the
terms of the Offer, all Shares validly tendered and not withdrawn prior to the
Expiration Date of the Offer. The Merger Agreement also provides that, if at
any scheduled Expiration Date of the Offer, the applicable waiting period
under the HSR Act or any other material competition law has not expired or has
not been terminated, the Purchaser and Merger Sub shall extend the Offer from
time to time (each such extension not to exceed ten business days after the
previously scheduled Expiration Date, unless the parties otherwise agree,
provided, that each party shall have the right to terminate the Merger
Agreement if the Offer is not completed by December 15, 2000), subject to any
right of the Purchaser, Merger Sub or the Company to terminate the Merger
Agreement pursuant to the terms hereof.

   The Company made representations and warranties to the Purchaser in the
Merger Agreement that (a) the Company's Board of Directors, at a meeting duly
called and held, (i) unanimously approved and adopted the Merger Agreement and
the transactions contemplated thereby, including the Offer and the Merger
(such approval being sufficient to render each of (y) Section 203 of the DGCL
and (z) Article Ninth of the Company's Certificate of Incorporation
inapplicable to the Merger Agreement and the transactions contemplated
thereby, including the Offer and the Merger), (ii) recommended that the
stockholders of the Company accept the Offer, tender their Shares pursuant to
the Offer and approve the Merger Agreement and the transactions contemplated
thereby, including the Merger, and (iii) determined that the Merger Agreement
and the transactions contemplated thereby, including the Offer and the Merger,
are fair to and in the best interests of the stockholders of the Company and
(b) J.P. Morgan, the Company's financial advisor, rendered its written opinion
to the Company's Board of Directors that the consideration to be received by
the holders of Shares and options of the Company pursuant to the Offer and the
Merger is fair to such holders from a financial point of view.

   The Merger Agreement provides that promptly upon the purchase by Merger Sub
of Shares pursuant to the Offer, and from time to time thereafter, the
Purchaser is entitled to designate such number of directors, rounded up to the
next whole number, on the Company's Board of Directors as is equal to at least
that number of directors equal to the product of the total number of directors
on the Company's Board of Directors (giving effect to the directors so elected
pursuant to such provision) multiplied by the percentage that the aggregate
number of Shares beneficially owned by the Purchaser or its affiliates bears
to the total number of Shares then outstanding. At such times, if requested by
the Purchaser, the Company will also cause each committee of the Company's
Board of Directors to include persons designated by the Purchaser constituting
the same percentage of each such committee as the Purchaser's designees are of
the Company's Board of Directors. The Company shall, upon

                                      20
<PAGE>

request by the Purchaser, promptly increase the size of the Company's Board of
Directors or exercise its best efforts to secure the resignations of such
number of directors as is necessary to enable the Purchaser's designees to be
elected to the Company's Board of Directors and shall cause the Purchaser's
designees to be so elected; provided, however, that, in the event that the
Purchaser's designees are appointed or elected to the Company's Board of
Directors, until the Effective Time, the Company's Board of Directors shall
have at least two directors who are directors on the date of the Merger
Agreement and who are neither officers of the Company nor designees,
stockholders, affiliates or associates (within the meaning of the federal
securities laws) of the Purchaser (one or more of such directors, the
"Independent Directors"); provided, further, that if no Independent Directors
remain, the other directors shall designate one person to fill one of the
vacancies who shall not be either an officer of the Company or a designee,
stockholder, affiliate or associate of the Purchaser, and such person shall be
deemed to be an Independent Director for purposes of the Merger Agreement.

   The Merger. The Merger Agreement provides that, at the Effective Time,
subject to the terms and conditions of the Merger Agreement and in accordance
with the DGCL, Merger Sub will be merged with and into the Company. Following
the Merger, the separate corporate existence of Merger Sub will cease and the
Company will continue as the Surviving Corporation.

   Unless otherwise determined by the Purchaser prior to the Effective Time,
at the Effective Time, the Certificate of Incorporation of the Company will be
amended to be in the form of the Certificate of Incorporation of Merger Sub,
as in effect immediately before the Effective Time, and will be the
Certificate of Incorporation of the Surviving Corporation until thereafter
amended in accordance with the provisions thereof and of applicable law. The
By-Laws of Merger Sub in effect immediately before the Effective Time will be
the By-Laws of the Surviving Corporation until amended, as provided by law,
the Certificate of Incorporation of the Surviving Corporation and such By-
Laws.

   The directors of Merger Sub immediately before the Effective Time will be
the initial directors of the Surviving Corporation, and the officers of Merger
Sub immediately before the Effective Time will be the initial officers of the
Surviving Corporation, in each case until the earlier of their death,
resignation or until their successors are elected or appointed and qualified.
If, at the Effective Time, a vacancy exists on the board of directors of the
Surviving Corporation or in any office of the Surviving Corporation, such
vacancy may thereupon be filled in a manner provided by applicable law.

   At the Effective Time, by virtue of the Merger and without any action on
the part of Merger Sub, or any holder of Shares or shares of Merger Sub, each
Share issued and outstanding immediately before the Effective Time (other than
(A) Shares held by the Purchaser, any direct or indirect wholly owned
subsidiary of the Purchaser or, in the treasury of the Company, which will be
canceled and extinguished immediately before the Effective Time and (B)
Dissenting Shares) will be canceled and extinguished and will be converted
into the right to receive $23.00 net per Share in cash, payable to the holder
thereof, without interest thereon (the "Per Share Amount"), upon surrender of
the certificate formerly representing such Share. At the Effective Time, each
share of common stock of Merger Sub, par value $0.01 per share, issued and
outstanding immediately before the Effective Time will thereafter represent
one validly issued, fully paid and non-assessable share of common stock, par
value $0.01 per share, of the Surviving Corporation.

   The Merger Agreement provides that, (i) reasonably promptly after Merger
Sub purchases Shares pursuant to the Offer constituting a majority of the
outstanding Shares on a fully diluted basis with respect to all options other
than the options of certain specified directors and (ii) immediately prior to
the Effective Time with respect to the options of such specified directors,
the Company shall cause each then outstanding option granted under any of the
Company's stock option plans (the "Option Plans") specified in the disclosure
schedules to the Merger Agreement (the "Options"), whether or not then
exercisable or vested, to be acquired by the Company for cancellation in
consideration of payment to the holders of such Options of an amount in
respect thereof equal to the product of (A) the excess if any, of the Per
Share Amount over the per share exercise price thereof and (B) the number of
Shares subject thereto (such payment to be net of applicable withholding
taxes); provided, that the Company shall obtain any consents required of
holders of Options to effect the foregoing and shall use all

                                      21

reasonable efforts to satisfy Rule 16b-3(e) promulgated under the Exchange Act
without incurring any liability in connection therewith. As promptly as
practicable following Merger Sub's purchase of a majority of the outstanding
Shares on a fully diluted basis, the Purchaser shall provide the Company with
the funds necessary to satisfy the foregoing obligations.

   The Company has agreed pursuant to the Merger Agreement that it shall cause
the Option Plans to terminate as of the Effective Time and shall ensure that
following the Effective Time no person, including any holder of Options or any
participant in the Option Plans, will have any right to acquire any equity
securities of the Company, the Surviving Corporation or any subsidiary
thereof.

   The Merger Agreement provides that immediately prior to the date the Offer
is completed, the Company will cause (i) all shares of restricted stock issued
to employees under any stock compensation plans or programs and (ii) shares
accruing under the Option Plans based on stock option exercises occurring
prior to the announcement of the transactions contemplated by the Merger
Agreement to become fully vested. The Merger Agreement provides that the Offer
will be made with respect to the Company's restricted shares and performance
shares.

   The Merger Agreement provides that no Options shall be offered to employees
of the Company and its subsidiaries for the year commencing on January 1, 2001
under the Company's employee stock purchase plan. If the Offer is completed
prior to December 31, 2000, then the options granted under such plan effective
January 1, 2000 shall be deemed fully vested with respect to the number of
shares attributable to employee deductions through the last payroll period
ending before the date the Offer is completed. The Company shall then cancel
such options in exchange for the payment described in the third preceding
paragraph.

   The Company has agreed pursuant to the Merger Agreement that, if required
by applicable law in order to consummate the Merger, following the purchase of
and payment for Shares by Merger Sub pursuant to the Offer, the Company shall
(i) promptly take all action necessary in accordance with the DGCL and its
Certificate of Incorporation and By-Laws to convene a special meeting of its
stockholders, (ii) use its best efforts to solicit from stockholders of the
Company proxies in favor of the Merger, if necessary, and (iii) take all other
action necessary or, in the reasonable opinion of the Purchaser, advisable to
secure any vote or consent of stockholders required by the DGCL to effect the
Merger. The Purchaser has agreed in the Merger Agreement that it will vote, or
cause to be voted, all of the Shares then directly or indirectly beneficially
owned by it in favor of the approval of the Merger.

   The Merger Agreement further provides that, notwithstanding the foregoing,
if the Purchaser, Merger Sub or any other subsidiary of the Purchaser acquires
at least 90% of the outstanding Shares of the Company pursuant to the Offer or
otherwise, the parties to the Merger Agreement will take all necessary and
appropriate action to cause the Merger to become effective as soon as
practicable after the acceptance for payment of and payment for the Shares by
Merger Sub pursuant to the Offer without a meeting of the stockholders of the
Company, in accordance with Section 253 of the DGCL. Additionally, pursuant to
the Merger Agreement, the Purchaser has agreed that if the Merger Agreement is
terminated in accordance with its terms, the Purchaser will cause the
stockholders' Shares to be promptly returned to the stockholders.

Agreement also provides that if the Merger Agreement is terminated, the

Agreement (other than documents filed with the SEC or that are otherwise
publicly available).

   Commercially Reasonable Efforts; Cooperation. The parties have agreed to
use their commercially 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 the transactions contemplated by the Merger Agreement,

consents and approvals, and to effect all necessary filings under the Exchange
Act and the HSR Act (and similar laws of other jurisdictions), to defend any
lawsuits or other proceedings challenging the Merger Agreement or the
consummation of the transactions contemplated thereby, including seeking to
have any stay or temporary restraining order entered by any court or other
governmental authority vacated or reversed, to execute and deliver any
additional instruments necessary to consummate the transactions contemplated
by, and to fully carry out the purposes of, the Merger Agreement. The parties
also agreed to cooperate in responding to inquiries from, and making
presentations to, regulatory authorities. For purposes of the Merger
Agreement, "commercially reasonable efforts" shall not be deemed to require
either the Purchaser or Merger Sub to take actions with respect to the defense
of any lawsuit or proceeding challenging the Merger Agreement or the
transactions contemplated thereby in connection with any competition laws
except in its sole discretion or to agree to, or proffer to, divest or hold
separate any assets or any portion of any business of the Purchaser, Merger
Sub, or the Company or any of their respective subsidiaries.

   Public Announcements. The Merger Agreement provides that the Company and
the Purchaser will consult with each other prior to issuing any press release
or otherwise making any public statement with respect to the Offer or the
Merger and not issue any press release or make any public statement prior to
such consultation, unless required by applicable law or applicable stock
exchange rules.

   Employee Benefit Arrangements. With respect to employee benefit matters,
the Merger Agreement provides that the Company shall adopt such amendments to
its benefit plans as reasonably requested by the Purchaser and as may be
necessary to ensure that its benefit plans cover only employees and former
employees (and their dependents and beneficiaries) of the Company and any of
its subsidiaries following the consummation of the transactions contemplated
by the Merger Agreement. With respect to any Shares held by any Company
benefit plan as of the date of the Merger Agreement or thereafter, the Company
shall take all actions necessary or appropriate (including such actions as are
reasonably requested by the Purchaser) to ensure that all participant voting
procedures contained in the Company benefit plans relating to such Shares, and
all applicable provisions of ERISA, are complied with in all material
respects.

   The Merger Agreement also provides that the Purchaser shall cause the
Company and its subsidiaries (or their successors) to continue to provide, for
a period of one year following the Effective Time, compensation and benefits
that are, in the aggregate, substantially comparable to the compensation and
benefits provided to the employees of the Company and its subsidiaries
immediately prior to the Effective Time. The Purchaser has agreed that at all
times following the Effective Time, to cause each of the employee benefit
plans and programs covering individuals who were employees of the Company and
its subsidiaries before the Effective Time to recognize service performed as
an employee of the Company or a subsidiary prior to the Effective Time. The

                                      25
<PAGE>

Purchaser has agreed that it will recognize such service for purposes of
determining each such individual's eligibility, vesting and rate of benefit
accrual, but the Purchaser shall not be required to cause such plans or
programs to credit such individuals with benefits for services performed prior
to the Effective Time.

   The Purchaser has also agreed under the Merger Agreement to cause any
successor to the Company resulting from the transactions contemplated by the
Merger Agreement to adopt the Company's 1998 Supplemental Benefit Plan so that
payment of the benefits earned by participants in such benefit plan up to the
Effective Time shall not be accelerated.

   Indemnification; Directors' and Officers' Insurance. The Merger Agreement
provides that all rights to indemnification and exculpation from liabilities

favor of the current or former directors, officers, employees and agents of
the Company or each of its subsidiaries (collectively, the "Indemnified
Parties") as provided in their respective certificate of incorporation or
bylaws (or comparable organizational documents) will be assumed by the
Purchaser and the Purchaser will be directly responsible for such
indemnification, without further action, as of the Effective Time and will
continue in full force and effect in accordance with their respective terms.
The Purchaser also agreed that from and after the Effective Time and for a
period of not less than six years thereafter, the Purchaser must, and will
cause the Surviving Corporation to, indemnify and hold harmless any and all
Indemnified Parties to the full extent such persons may be indemnified by the
Company or such subsidiaries, as the case may be, pursuant to applicable law,
their respective certificates or articles of incorporation or by-laws (or
other organizational documents) or pursuant to indemnification agreements as
in effect on the date of the Merger Agreement for acts or omissions occurring
at or prior to the Effective Time. The Purchaser also agreed that, from and
after the Effective Time, directors and officers of the Company who become or
remain directors or officers of the Purchaser or the Surviving Corporation
will be entitled to the same indemnity rights and protections (including those
provided by directors' and officers' liability insurance) of the Purchaser.
Additionally, the Purchaser has agreed that, notwithstanding any other
provision contained in the Merger Agreement, the provisions of the Merger
Agreement relating to indemnification of officers and directors (i) are
intended to be for the benefit of, and will be enforceable by, each
Indemnified Party, his or her heirs and his or her representatives and (ii)
are in addition to, and not in substitution for, any other rights to
indemnification or contribution that any such person may have by contract or
otherwise.

   The Merger Agreement provides further that for at least six years after the
Effective Time, the Purchaser will, and will cause the Surviving Corporation
to, maintain in effect officers' and directors' liability insurance covering
the Indemnified Parties who are currently covered by the Company's officers
and directors liability insurance policy containing terms and conditions which
are no less advantageous to the persons currently covered by such policies are
insured than those in effect on the date of the Merger Agreement with respect
to matters existing or occurring prior to the Effective Time; provided,
however, that the Surviving Corporation will not be required to expend in any
year an amount in excess of 200% of the annual aggregate premiums currently
paid by the Company for such insurance; and provided, further, that if the
annual premiums of such insurance coverage exceed such amount, the Surviving
Corporation will be obligated to obtain a policy with the best coverage
available, in the reasonable judgment of its board of directors, for a cost
not exceeding such amount. The Purchaser has agreed that these provisions will
survive consummation of the Merger and be binding on and assumed by all
successors and assigns of the Surviving Corporation.

   Transfer Taxes. The Merger Agreement provides that the Purchaser and the
Company must cooperate in the preparation, execution and filing of all
returns, applications or other documents regarding any transfer taxes, real
property transfer, stamp, recording, documentary or other taxes and any other
fees and similar taxes which become payable in connection with the Merger
(collectively, "Transfer Taxes"). Additionally, the Merger Agreement provides
that the Purchaser shall pay or cause to be paid, without deduction or
withholding from any amounts payable to the holders of Shares, all Transfer
Taxes.

   Additional Agreements. The Company, Merger Sub and the Purchaser have
agreed to each comply in all material respects with all applicable laws and
with all applicable rules and regulations of any governmental authority in
connection with its execution, delivery and performance of the Merger

have also agreed to use all commercially reasonable efforts to obtain in a
timely manner all necessary waivers, consents and approvals and to effect all
necessary registrations and filings, and to use all commercially reasonable

to be done, all other things necessary, proper or advisable to consummate and
make effective as promptly as practicable the transactions contemplated by the
Merger Agreement.

   Notification of Certain Matters. The Purchaser and the Company have agreed
to promptly notify each other of (i) the occurrence or non-occurrence of any
event which would be likely to cause either (A) any representation or warranty
contained in the Merger Agreement to be untrue or inaccurate in any material
respect at any time from the date of the Merger Agreement to the Effective
Time or (B) any condition to the Offer to be unsatisfied in any material
respect at any time from the date of the Merger Agreement to the date the
Offer is completed and (ii) any material failure of the Company, Merger Sub or
the Purchaser, as the case may be, or any officer, director, employee or agent
thereof, to comply with or satisfy any covenant, condition or agreement to be
complied with or satisfied by it under the Merger Agreement. Delivery of any
such notice will not limit or otherwise affect the remedies available to the
receiving party.

   No Solicitation. The Merger Agreement provides that the Company and its
subsidiaries and their respective officers, directors, employees,
representatives and agents will immediately cease all existing activities,
discussions and negotiations, if any, with any parties conducted prior to the
execution of the Merger Agreement with respect to any Acquisition Proposal and
must request the return of all confidential information regarding the Company
and its subsidiaries provided to any such parties after January 1, 1999 and
prior to the date of the Merger Agreement pursuant to a confidentiality
agreement executed in connection with or in contemplation of an Acquisition
Proposal. The Merger Agreement further provides that the Company shall not,
nor shall it permit any of its subsidiaries to, directly or indirectly through

constitutes or reasonably may give rise to, an Acquisition Proposal or (ii)
participate in any discussions or negotiations regarding such Acquisition
Proposal; provided, that at any time prior to the date on which Merger Sub

Completion Date"), the Company's Board of Directors may, in the exercise of
its fiduciary obligations under Delaware Law as determined by the Company's
Board of Directors in good faith, after consultation with its outside counsel
(who may be its regularly engaged outside counsel) in response to an
unsolicited written Acquisition Proposal, make such inquiries of the party
making such unsolicited Acquisition Proposal as may be necessary to inform
itself of the proposed terms and details of the Acquisition Proposal and, if
the Company's Board of Directors reasonably believes that such Acquisition
Proposal may lead to a Superior Proposal (as defined below) pursuant to a
customary confidentiality agreement with terms not more favorable to such
third party than the Confidentiality Agreement, by and between the Purchaser
and the Company (the "Confidentiality Agreement") (excluding the standstill
provisions contained therein), furnish information to, and negotiate or
otherwise engage in discussions with, the third party who delivers such
Acquisition Proposal. As used herein, (i) "Superior Proposal" means an
Acquisition Proposal (A) that the Company's Board of Directors determines in

view than the transactions contemplated by the Merger Agreement (including any
adjustment to the terms and conditions proposed by the Purchaser in response
to such Acquisition Proposal), (B) that is made by a person reasonably capable
of completing such Acquisition Proposal, taking into account the legal,
financial and regulatory aspects of such Acquisition Proposal and the person
making such Acquisition Proposal, and (C) for which financing, to the extent
required, is then committed or which, in the good faith judgment of the
Company's Board of Directors, is reasonably capable of being obtained by the
person making the Acquisition Proposal, and (ii) "Acquisition Proposal" means
any inquiry, proposal or offer from any person relating to any (A) direct or
indirect acquisition or purchase of a business that constitutes 10% or more of
the net revenues or assets of the Company and its subsidiaries taken as a
whole, or (B) direct or indirect acquisition or purchase of 10% or more of any
class of equity securities of the Company or any of its subsidiaries whose
business constitutes 10% or more of the net revenues or assets of the Company
and its subsidiaries taken as a whole, (C)

                                      27
<PAGE>

Person beneficially owning 10% or more of any class of equity securities of
the Company or any of its subsidiaries whose business constitutes 10% or more
of the net revenues or assets of the Company and its subsidiaries taken as a
whole, or (D) any merger, consolidation, business combination,
recapitalization, liquidation, dissolution or similar transaction involving
the Company or any of its subsidiaries whose business constitutes 10% or more
of the net revenues or assets of the Company and its subsidiaries taken as a
whole, other than the transactions contemplated by the Merger Agreement. The
Merger Agreement also provides that the Company shall promptly (but in any
event within one calendar day) advise the Purchaser in writing of (i) the
receipt, directly or indirectly, of any inquiries or proposals indicating that
a person is considering making an Acquisition Proposal (including the specific

relating to a possible Acquisition Proposal and copies of any written
information provided to or by any third party relating thereto to the extent

illegal or restraining, enjoining or otherwise prohibiting or materially
restricting the consummation of the Merger; provided, that this condition
shall be deemed to have been satisfied with respect to the obligation of the
Purchaser and Merger Sub to effect the Merger if the Purchaser's or Merger
Sub's failure to comply with its obligations relating to using its
commercially reasonable efforts and cooperation to take actions necessary to
consummate the transactions contemplated by the Merger Agreement, materially
contributed to the issuance of any such judgment, writ, decree, order or
injunction.

   The obligations of the Purchaser and Merger Sub to effect the Merger are
further subject to the satisfaction or waiver of the condition that prior to
the Effective Time, the Company shall have performed in all material respects
all of its obligations under the Merger Agreement required to be performed by
it at or prior to the Effective Time.

   Termination and Fees. The Merger Agreement may be terminated at any time
before the Effective Time, whether before or after stockholder approval: (i)
by mutual written consent of the Purchaser's Board of Directors and the
Company's Board of Directors; or (ii) by either the Purchaser or the Company
if a court of competent jurisdiction or governmental, regulatory or
administrative agency or commission shall have issued an order, decree or
ruling or taken any other action in each case permanently restraining,
enjoining or otherwise prohibiting the transactions contemplated by the Merger
Agreement and such order, decree or ruling shall have become final and
appealable; provided, that no party may terminate the Merger Agreement under
this clause (ii) if such party's failure to fulfill any of its obligations
under the Merger Agreement shall have materially contributed to the issuance
of any such order, decree or ruling; or (iii) by either the Purchaser or the
Company if the Offer has not been consummated by August 15, 2000 (or, if a
request for additional information is received from a

                                      28
<PAGE>

governmental authority pursuant to the HSR Act, within 40 calendar days after
compliance with such request for additional information but in no event later
than December 15, 2000); provided, that no party may terminate the Merger
Agreement pursuant to item (iii) above if such party's failure to fulfill any
of its obligations under the Merger Agreement shall have been the reason that
the Offer shall not have been consummated on or before said date; or (iv) by
the Company (a) if there shall be a material breach of any of the Purchaser's
or Merger Sub's representations or warranties under the Merger Agreement,
which breach is not curable or if curable, shall not have been cured within 30
calendar days of the receipt of written notice thereof by the Purchaser or
Merger Sub from the Company, (b) if there shall have been a material breach on
the part of the Purchaser or Merger Sub of any of their respective covenants
or agreements under the Merger Agreement which breach is not curable or if
curable, shall not have been cured within 30 calendar days of the receipt of
written notice thereof by the Purchaser or Merger Sub from the Company, or (c)
in accordance with the procedures set forth in the Merger Agreement relating
to termination of the Merger Agreement where there is a Superior Proposal; or
(v) by the Purchaser if (a) there shall be a material breach of any of the
Company's representations or warranties in the Merger Agreement relating to
capitalization, (b) there shall be a material breach of any of the Company's
other representations or warranties contained in the Merger Agreement (without
giving effect to any materiality or material adverse effect qualifications
contained in the Merger Agreement), except for such breach that would not be
reasonably expected to have or result in, individually or in the aggregate, a
Company Material Adverse Effect, or (c) there shall have been a material
breach by the Company of any of its material covenants or agreements under the
Merger Agreement, which breach, in the case of each of clauses (a), (b) and
(c) above, is not curable or if curable, shall not have been cured within 30
calendar days of the receipt of written notice thereof by the Company from the
Purchaser or Merger Sub; or (vi) by the Purchaser, at any time prior to the
Offer Completion Date, if (A) the Company's Board of Directors shall have (a)
withdrawn or modified in a manner adverse to the Purchaser and Merger Sub its
recommendation or approval of the Merger Agreement, the Offer or the Merger,
(b) recommended or approved, or proposed publicly to recommend or approve, a
third-party Acquisition Proposal, (c) caused or authorized the Company or any
of its subsidiaries to enter into an Acquisition Agreement, or (d) resolved or
publicly disclosed any intention to take any of the foregoing actions, or (B)
any person or group (as defined in Section 13(d)(3) of the Exchange Act) other
than the Purchaser, Merger Sub or any of their respective subsidiaries or
affiliates shall have become the beneficial owner of more than 50% of the
outstanding Shares (either on a primary or a fully diluted basis); or (vii) by
either the Purchaser or the Company if the Offer expires or is terminated or
withdrawn pursuant to its terms without any Shares being purchased thereunder
by Merger Sub as a result of any failure of the conditions of the Offer.

   The Merger Agreement provides that in the event of termination of the
Merger Agreement and the abandonment of the Merger and the other transactions
contemplated by the Merger Agreement, the Company will pay to the Purchaser an
amount equal to $13.0 million (the "Termination Fee") in any of the following
circumstances: (i) the Merger Agreement is terminated at such time the Merger
Agreement is terminable as described in clause (iv) (c) or clause (vi) of the
preceding paragraph; or (ii) the Merger Agreement is terminated by either the
Purchaser or the Company as described in clause (iii) of the preceding
paragraph, and (a) at the time of such termination, the Minimum Condition
shall not have been satisfied, (b) at the time of such termination, the
Company shall not have the right to terminate the Merger Agreement as
described in clauses (iv)(a) or (b) of the preceding paragraph, (c) prior to
such termination, an Acquisition Proposal involving at least 50% of the assets
of the Company and its subsidiaries, taken as a whole, or 50% of any class of
equity securities of the Company (any such Acquisition Proposal, a "Competing
Proposal"), is (y) publicly disclosed or has been made directly to
stockholders of the Company generally or (z) any person (including without
limitation the Company or any of its subsidiaries) publicly announces an
intention (whether or not conditional) to make such a Competing Proposal, and
(d) prior to the termination of the Merger Agreement or within twelve months
after the termination of the Merger Agreement, the Company or any subsidiary
thereof enters into an Acquisition Agreement providing for a Competing
Proposal (any such agreement, a "Competing Proposal Agreement") or the
transactions contemplated by a Competing Proposal are consummated; or (iii)
the Merger Agreement is terminated by either the Purchaser or the Company as
described in clause (vii) of the preceding paragraph, and (a) at the time of
such termination, the Minimum Condition shall not have been satisfied, (b) at
the time of such termination, the Company shall not have the right to
terminate the Merger Agreement as described in clauses

                                      29
<PAGE>

(iv) (a) or (b) of the preceding paragraph, (c) prior to such termination, an
event as described in clause (ii) (c) of this paragraph (a "Takeover Proposal
Event") shall have occurred and (d) prior to the termination of the Merger
Agreement or within twelve months after the termination of the Merger
Agreement, the Company or any subsidiary thereof enters into a Competing
Proposal Agreement or the transactions contemplated by a Competing Proposal
are consummated; or (iv) the Merger Agreement is terminated by the Purchaser
as described in clause (v) of the preceding paragraph, and (a) prior to such
termination, a Takeover Proposal Event shall have occurred; and (b) prior to
the termination of the Merger Agreement or within twelve months after the
termination of the Merger Agreement, the Company or a subsidiary thereof
enters into a Competing Proposal Agreement or the transactions contemplated by
a Competing Proposal are consummated.

   If a Termination Fee is payable pursuant to any of clauses (ii), (iii) or
(iv) of the preceding paragraph, then the Company will pay the Termination Fee
to the Purchaser upon the signing of a Competing Proposal Agreement or, if no
Competing Proposal Agreement is signed, then at the closing (and as a
condition to the closing) of a Competing Proposal. Notwithstanding any other
provision of the Merger Agreement, (i) in no event may the Company enter into
a Competing Proposal Agreement, unless, prior thereto or concurrent therewith,
the Company has paid any amount due under the provisions of the Merger
Agreement providing for a termination fee, (ii) the Company may not terminate
the Merger Agreement under clause (iv) (c) of the second preceding paragraph
unless prior thereto it has paid all amounts due under the Merger Agreement to
the Purchaser, (iii) all amounts due in the event that the Merger Agreement is
terminated as described in clause (vi) of the second preceding paragraph and
in circumstances in which the Company has not entered into a Competing
Proposal Agreement will be payable promptly, but in no event more than two
business days after request for such payment is made, and (iv) all amounts due
under the provisions of the Merger Agreement providing for a termination fee
will be paid on the date due in immediately available funds wire transferred
to the account designated by the person entitled to such payment.

   The Merger Agreement further provides that, except as set forth above, all
fees, costs and expenses incurred in connection with the Offer, the Merger,
the Merger Agreement and the transactions contemplated thereby will be paid by
the party incurring such fees, costs and expenses.

   Amendment. The Merger Agreement may be amended by the Company, the
Purchaser and Merger Sub by action taken by each such party's Board of
Directors at any time before the Effective Time and at any time before or
after any approval of the Merger Agreement by the stockholders of the Company
but, after any such approval, no amendment will be made that reduces the
amount or changes the type of consideration into which each Share will be
converted upon consummation of the Merger. The Merger Agreement may not be
amended except by an instrument in writing signed by the parties.

   Extension; Waiver. At any time before the Effective Time, any party to the
Merger Agreement may (a) extend the time for the performance of any of the
obligations or other acts of the other parties, (b) waive any inaccuracies in
the representations and warranties contained in the Merger Agreement or in any
document delivered pursuant to the Merger Agreement and any other documents
related thereto, and (c) waive compliance with any of the agreements or
conditions contained in the Merger Agreement. Any agreement on the part of a
party to the Merger Agreement to any such extension or waiver shall be valid
only as against such party and only if set forth in an instrument in writing
signed by such party. Any such waiver shall constitute a waiver only with
respect to the specific matter described in such writing and shall in no way
impair the rights of the party granting such waiver in any other respect or at
any other time. Neither the waiver by any of the parties to the Merger
Agreement of a breach of or a default under any of the provisions of the
Merger Agreement, nor the failure by any of the parties, on one or more
occasions, to enforce any of the provisions of the Merger Agreement or to
exercise any right or privilege under the Merger Agreement, shall be construed
as a waiver of any other breach or default of a similar nature, or as a waiver
of any of such provisions, rights or privileges under the Merger Agreement.
The rights and remedies provided in the Merger Agreement are cumulative and
none is exclusive of any other, or of any rights or remedies that any party
may otherwise have at law or in equity.

Stockholder Tender Agreement

   The following is a summary of the material terms of the Tender Agreement
and is qualified in its entirety by reference to the copy of the Tender
Agreement filed as an exhibit to the Schedule TO and incorporated herein by
reference.

   In connection with the execution of the Merger Agreement, James Carroll,
the Chairman of the Board and Chief Executive Officer of the Company, who
beneficially owns 1,086,903 of the Shares (the "Carroll Shares"), has entered
into the Tender Agreement with Merger Sub and the Purchaser.

   Tender of Shares. Mr. Carroll has agreed to tender (and not withdraw) all
of the Carroll Shares pursuant to and in accordance with the terms of the
Offer not later than the fifth business day after commencement of the Offer.

   Transfer of Shares. Mr. Carroll has agreed that during the term of the
Tender Agreement, he will not (a) except as provided in the Tender Agreement,
offer to sell, transfer, pledge, assign, hypothecate or otherwise dispose of
or transfer any interest in or encumber with any lien, any of the Carroll
Shares, (b) deposit the Carroll Shares into a voting trust, enter into a
voting agreement or arrangement with respect to the Carroll Shares or grant
any proxy or power of attorney with respect to the Carroll Shares, or (c)
enter into any contract, option or other arrangement or undertaking with
respect to the direct or indirect acquisition or sale, assignment or other
disposition of or transfer of any interest in or the voting of any shares of
common stock or any other securities of the Company beneficially owned by Mr.
Carroll.

   Grant of Proxy. Mr. Carroll has agreed to revoke any and all prior proxies
with respect to the Carroll Shares that he may have made or granted prior to
the Tender Agreement and has constituted and appointed the Purchaser, or any
nominee of the Purchaser, with full power of substitution, during and for the
term of the Tender Agreement, as his true and lawful attorney and proxy, for
and in his name, place and stead, to vote each of such Carroll Shares, at any
annual, special or adjourned meeting of the stockholders of the Company
(including the right to sign his name (as stockholder) to any consent,
certificate or other document relating to the Company permitted by the DGCL)
(i) in favor of the Merger, the execution and delivery by the Company of the
Merger Agreement and the approval and adoption of the Merger and the
transactions contemplated thereby and by the Tender Agreement and (ii) against
(A) any action or agreement that would result in a breach in any respect of
any covenant, agreement, representation or warranty of the Company under the
Merger Agreement and (B) the following actions (other than the Merger and the
other transactions contemplated by the Merger Agreement): (1) any
extraordinary corporate transactions, such as a merger, consolidation or other
business combination involving the Company or its subsidiaries; (2) a sale,
lease or transfer of all or substantially all of the assets of the Company or
one of its material subsidiaries, or a reorganization, recapitalization,
dissolution or liquidation of the Company or its subsidiaries; (3) (a) any
change in a majority of the persons who constitute the board of directors of
the Company as of the date of the Tender Agreement; (b) any change in the
capitalization of the Company or as of the date of the Tender Agreement any
amendment of the Company's Certificate of Incorporation or By-Laws, as amended
to the date of the Tender Agreement; (c) any other material change in the
Company's corporate structure or business; or (d) any other action that, in
the case of each of the matters referred to in (3)(a), (b), (c) and (d), is
intended, or could reasonably be expected to impede, interfere with, delay,
postpone, or adversely affect the Merger and the other transactions
contemplated by the Merger Agreement. The proxy is coupled with an interest,
and Mr. Carroll has declared it to be irrevocable.

   Termination. The Tender Agreement will terminate on the earlier of (i) the
purchase of all the Carroll Shares pursuant to the Offer or (ii) the date the
Merger Agreement is terminated in accordance with its terms. In the event the
Tender Agreement is terminated in accordance with its terms, the Purchaser has
agreed to cause all of the Carroll Shares to be promptly returned to Mr.
Carroll.

Consulting Agreement

   The Purchaser and James Carroll entered into a Consulting Agreement, dated
as of June 13, 2000 (the "Consulting Agreement"), pursuant to which the
Purchaser has agreed to retain Mr. Carroll as a consultant for a

                                      31
<PAGE>

two-year period beginning on the consummation of the Merger. In consideration
for his services, Mr. Carroll will receive an annual consulting fee of
$300,000.

Statutory Requirements

   In general, under the DGCL a merger of two Delaware corporations requires
the adoption of a resolution by the Board of Directors of each of the
corporations desiring to merge approving an agreement of merger containing
provisions with respect to certain statutorily specified matters and the
approval of such agreement of merger by the stockholders of each corporation
by the affirmative vote of the holders of a majority of all the outstanding
shares of stock entitled to vote on such merger. According to the Company's
Certificate of Incorporation, the Shares are the only securities of the
Company that entitle the holders thereof to voting rights.

   The DGCL also provides that if a parent company owns at least 90% of each
class of stock of a subsidiary, the parent company can effect a short-form
merger with that subsidiary without any action by or approval of the other
stockholders of the subsidiary. Accordingly, if as a result of the Offer or
otherwise Merger Sub acquires or controls the voting power of at least 90% of
the Shares, Merger Sub could, and intends to, effect the Merger without prior
notice to, or any action by, any other stockholder of the Company.

Appraisal Rights

   The holders of Shares do not have appraisal rights as a result of the
Offer. However, if the Merger is consummated, holders of Shares at the
Effective Time will have certain rights pursuant to the provisions of Section
262 of the DGCL ("Section 262") to dissent and demand appraisal of their
Shares. Under Section 262, dissenting stockholders 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, if any. Any such judicial determination of the fair value of 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 Section 262 does not purport to be complete and is
qualified in its entirety by reference to Section 262, a copy of which is
attached to the Purchaser's Schedule TO. Failure to follow the steps required
by Section 262 of the DGCL for perfecting appraisal rights may result in the
loss of such rights.

Plans for the Company

   If a majority of the outstanding Shares are purchased by Merger Sub
pursuant to the Offer, the Purchaser may designate its representatives as a
majority of the Company's Board of Directors. Following completion of the
Offer and the Merger, the Purchaser intends to integrate the Company's seal
operations with those of the Purchaser under the direction of the Purchaser's
management. The Purchaser's principal reason for acquiring the Company is the
strategic fit of the Company's seal operations with the Purchaser's seal
operations. The Purchaser intends to continue to review the Company and its
assets, corporate structure, dividend policy, capitalization, operations,
properties, policies, management and personnel and to consider, subject to the
terms of the Merger Agreement, what, if any, changes would be desirable in
light of the circumstances then existing, and reserves the right to take such
actions or effect such changes as it deems desirable. Such changes could
include changes in the Company's corporate structure, operational
headquarters, capitalization, management or dividend policy. In addition, the
Purchaser will be reviewing the Company's specialty chemical business to
determine its plans with respect to such business.

12. Source and Amount of Funds

   The Offer is not conditioned on any financing arrangements.

   The total amount of funds required by Merger Sub to purchase all
outstanding Shares pursuant to the Offer and to pay fees and expenses related
to the Offer and the Merger is estimated to be approximately $438.0 million.

                                      32
<PAGE>

Merger Sub plans to obtain all funds needed for the Offer and the Merger
through capital contributions that will be made by the Purchaser, either
directly or through one or more wholly owned subsidiaries of the Purchaser, to
Merger Sub. The Purchaser currently anticipates that it will make a portion of
these contributions through funds that it will receive under its commercial
paper program, which is backed by existing revolving credit arrangements. In
addition, the Purchaser has on file with the SEC an effective shelf
registration statement, pursuant to which it may elect to issue debt
securities prior to or following the consummation of the Offer. The proceeds
of any such issuance might be used to finance or refinance all or a part of
the consideration of the Offer.

   If Purchaser does not wish to or is unable to obtain the funds as outlined
above, it will develop an alternative financing plan.

13. Certain Conditions of the Offer

   Notwithstanding any other provision of the Offer or the Merger Agreement,
Merger Sub shall not be required to accept for payment or, subject to any
applicable rules and regulations of the SEC, including Rule 14e-1(c)
promulgated under the Exchange Act (relating to Merger Sub's obligation to pay
for or return tendered Shares promptly after termination or withdrawal of the
Offer), pay for, and (subject to any such rules or regulations) may delay the
acceptance for payment of any tendered Shares and (except as provided in the
Merger Agreement) amend or terminate the Offer as to any Shares not then paid
for (A) unless the following conditions shall have been satisfied: (i) there
shall be validly tendered and not withdrawn prior to the expiration of the
Offer a number of Shares that represents at least a majority of the number of
Shares outstanding on a fully diluted basis (assuming the exercise of all
outstanding options and any other rights to acquire common stock of the
Company on the date of purchase and assuming the issuance of the Company's
performance shares on the date of purchase) (the "Minimum Condition"), (ii)
any applicable waiting period under the HSR Act and any extension thereof
shall have expired or been terminated prior to the expiration of the Offer,
and (iii) any other requisite waiting periods under any other material
competition law shall have terminated or expired, or (B) if at any time after
the date of the Merger Agreement and before the time of payment for any such
Shares (whether or not any Shares have theretofore been accepted for payment
or paid for pursuant to the Offer), any of the following conditions exists:

     (a) there shall have been any action or proceeding brought or formally
  threatened by a governmental, regulatory or administrative authority,
  agency or commission of competent jurisdiction or any other person or
  entity (other than any action or proceeding brought by a person or entity
  other than a governmental, regulatory or administrative authority, agency
  or commission which if decided adversely would not reasonably be expected
  to cause a Company Material Adverse Effect) or a statute, rule, regulation,
  executive order or other action shall have been promulgated, enacted, taken
  or threatened by a governmental authority or a governmental, regulatory or
  administrative agency or commission of competent jurisdiction which would
  have the effect of (i) restraining or prohibiting the making or
  consummation of the Offer or the consummation of the Merger, (ii)
  prohibiting or restricting the ownership or operation by the Purchaser (or
  any of its affiliates or subsidiaries) of any portion of its or the
  Company's business or assets, or compelling the Purchaser (or any of its
  affiliates or subsidiaries) to dispose of or hold separate any portion of
  its or the Company's business or assets, (iii) imposing material
  limitations on the ability of the Purchaser (or any of its affiliates and
  subsidiaries) effectively to acquire or to hold or to exercise full rights
  of ownership of the Shares purchased by Merger Sub, including, without
  limitation, the right to vote the Shares purchased by Merger Sub on all
  matters properly presented to the stockholders of the Company, or (iv)
  imposing any material limitation on the ability of the Purchaser or any of
  its affiliates or subsidiaries effectively to control in any material
  respect the business and operations of the Company or which would otherwise
  have a Company Material Adverse Effect; or

     (b) there shall be in effect any injunction, order, decree, judgment or
  ruling issued by a court of competent jurisdiction having any effect set
  forth in paragraph (a) above; or

     (c) the Merger Agreement shall have been terminated by the Company or
  the Purchaser in accordance with its terms; or

                                      33
<PAGE>

     (d) (i) (A) certain representations and warranties of the Company
  regarding the capitalization of the Company shall not be true and correct
  in all material respects when made or (B) any other representation or
  warranty made by the Company in the Merger Agreement shall not have been
  true and correct in all respects when made, or shall have ceased to be true
  and correct in all respects as of the Expiration Date (without giving
  effect to any materiality or material adverse effect qualifications
  contained therein) as if made as of such date (except to the extent such
  representations and warranties of the Company address matters only as a
  particular date, in which case as of such date) except for such failure to
  be true and correct that would not be reasonably expected to have or result
  in, individually or in the aggregate, a Company Material Adverse Effect or
  (ii) as of the Expiration Date the Company shall not in all material
  respects have performed any obligation or agreement and complied with its
  material covenants to be performed and complied with by it under this
  Agreement; or

     (e) there shall have occurred (i) any suspension or limitation of
  trading in securities generally on the NYSE (not including any suspension
  or limitation of trading in any particular security as a result of
  computerized trading limits or any intraday suspension due to "circuit
  breakers") or any setting of minimum prices for trading on such exchange,
  (ii) any banking moratorium declared by the U.S. federal or New York
  authorities or any suspension of payments in respect of banks in the United
  States, (iii) any material limitation (whether or not mandatory) by any
  governmental authority on the extension of credit by commercial banks or
  other commercial lending institutions, (iv) a commencement of a war or
  armed hostilities or other national or international calamity directly or
  indirectly involving the United States, or (v) in the case of any of the
  foregoing existing on the date hereof, a material acceleration or worsening
  thereof; or

     (f) there shall have occurred any event that, individually or when
  considered together with any other matter, has had or would reasonably be
  likely in the future to have a Company Material Adverse Effect; or

     (g) the Company Board of Directors shall have (a) withdrawn or modified
  or changed (including by amendment of the Schedule 14D-9) its
  recommendation of the Offer, the Merger or the Merger Agreement in a manner
  adverse to the Purchaser or Merger Sub, (b) publicly taken a position
  inconsistent with its recommendation of the Offer, the Merger or the Merger
  Agreement in a manner adverse to the Purchaser or Merger Sub, (c) approved
  or recommended any Acquisition Proposal, (d) caused the Company to enter
  into an Acquisition Agreement, or (e) resolved or publicly disclosed any
  intention to do any of the foregoing.

   The foregoing conditions are for the sole benefit of the Purchaser and may
be asserted by the Purchaser regardless of the circumstances (including any
action or inaction by the Purchaser) giving rise to any such conditions and
may be waived by the Purchaser in whole or in part at any time and from time
to time, in each case, in the exercise of the good faith judgment of the
Purchaser and subject to the terms of the Merger Agreement. The failure by the
Purchaser at any time to exercise any of the foregoing rights shall not be
deemed a waiver of any such right and each such right shall be deemed an
ongoing right which may be asserted at any time and from time to time.

   A public announcement may be made of a material change in, or waiver of,
such conditions and the Offer may, in certain circumstances, be extended in
connection with any such change or waiver.

14. Certain Legal Matters; Required Regulatory Approvals

   Except as set forth in this Offer to Purchase, based on its review of
publicly available filings by the Company with the SEC and other information
regarding the Company, neither the Purchaser nor Merger Sub is aware of any
licenses or regulatory permits that appear to be material to the business of
the Company and its subsidiaries, taken as a whole, and that might be
adversely affected by Merger Sub's acquisition of Shares (and the indirect
acquisition of the stock of the Company's subsidiaries) as contemplated
herein, or any filings, approvals or other actions by or with any domestic,
foreign or supranational governmental authority or administrative or
regulatory agency that would be required for the acquisition or ownership of
the Shares (or the indirect acquisition of the stock of the Company's
subsidiaries) by Merger Sub pursuant to the Offer as

                                      34
<PAGE>

contemplated herein. Should any such approval or other action be required, it
is presently contemplated that such approval or action would be sought except
as described below under "State Takeover Laws." Should any such approval or
other action be required, there can be no assurance that any such approval or
action would be obtained at all or without substantial conditions or that
adverse consequences would not result to the Company's or its subsidiaries'
businesses, or that certain parts of the Company's, the Purchaser's, Merger
Sub's or any of their respective subsidiaries' businesses might not have to be
disposed of or held separate or other substantial conditions complied with in
order to obtain such approval or action or in the event that such approvals
were not obtained or such actions were not taken. Merger Sub's obligation to
purchase and pay for Shares is subject to certain conditions, including
conditions with respect to litigation and governmental actions. See the
Introduction and Section 13 for a description thereof.

   State Takeover Laws. A number of states (including Delaware, which is the
Company's state of incorporation) have adopted takeover laws and regulations
which purport, to varying degrees, to be applicable to attempts to acquire
securities of corporations which are incorporated in such states or which have
substantial assets, stockholders, principal executive offices or principal
places of business therein. To the extent that certain provisions of certain
of these state takeover statutes purport to apply to the Offer or the Merger,
Merger Sub believes that such laws conflict with federal law and constitute an
unconstitutional burden on interstate commerce. In 1982, the Supreme Court of
the United States, in Edgar v. Mite Corp., invalidated on constitutional
grounds the Illinois Business Takeovers Statute, which as a matter of state
securities law made takeovers of corporations meeting certain requirements
more difficult. The reasoning in such decision is likely to apply to certain
other state takeover statutes. In 1987, however, in CTS Corp. v. Dynamics
Corp. of America, the Supreme Court of the United States held that the State
of Indiana could as a matter of corporate law and, in particular, those
aspects of corporate law concerning corporate governance, constitutionally
disqualify a potential acquiror from voting on the affairs of a target
corporation without the prior approval of the remaining stockholders, provided
that such laws were applicable only under certain conditions. Subsequently, in
TLX Acquisition Corp. v. Telex Corp., a United States district court in
Oklahoma ruled that the Oklahoma statutes were unconstitutional insofar as
they apply to corporations incorporated outside Oklahoma in that they would
subject such corporations to inconsistent regulations. Similarly, in Tyson
Foods, Inc. v. McReynolds, a United States district court in Tennessee ruled
that four Tennessee takeover statutes were unconstitutional as applied to
corporations incorporated outside Tennessee. This decision was affirmed by the
United States Court of Appeals for the Sixth Circuit. In December 1988, a
United States district court in Florida held, in Grand Metropolitan PLC v.
Butterworth, that the provisions of the Florida Affiliated Transactions Act
and Florida Control Share Acquisition Act were unconstitutional as applied to
corporations incorporated outside of Florida.

   Merger Sub has not attempted to comply with any state takeover statutes in
connection with the Offer or the Merger although, pursuant to the Merger
Agreement, the Company has represented that the Company's Board of Directors
has taken appropriate action to render Section 203 of the DGCL inapplicable to
the Offer, the Merger and the transactions contemplated by the Merger
Agreement. Merger Sub reserves the right to challenge the validity or
applicability of any state law allegedly applicable to the Offer or the
Merger, and nothing in this Offer to Purchase nor any action taken in
connection herewith is intended as a waiver of that right. In the event that
it is asserted that one or more state takeover statutes apply to the Offer or
the Merger, and it is not determined by an appropriate court that such statute
or statutes do not apply or are invalid as applied to the Offer or the Merger,
as applicable, Merger Sub may be required to file certain documents with, or
receive approvals from, the relevant state authorities, and Merger Sub might
be unable to accept for payment or purchase Shares tendered pursuant to the
Offer or be delayed in continuing or consummating the Offer. In such case,
Merger Sub may not be obligated to accept for purchase, or pay for, any Shares
tendered. See Section 13.

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

                                      35

   Under the provisions of the HSR Act applicable to the Offer and the Merger,
the purchase of Shares pursuant to the Offer and the Merger may not be
consummated until the expiration of a 15 calendar day waiting period following
the filing of certain required information and documentary material with
respect to the Offer with the FTC and the Antitrust Division, unless such
waiting period is earlier terminated by the FTC and the Antitrust Division.
The Purchaser expects to file a Premerger Notification and Report Form with
the FTC and the Antitrust Division in connection with the purchase of Shares
pursuant to the Offer and the Merger under the HSR Act on or about June 23,
2000, and the required waiting period with respect to the Offer and the Merger
will expire at 11:59 p.m., New York City time, on July 8, 2000 (assuming a
June 23, 2000 filing), unless earlier terminated by the FTC or the Antitrust
Division or the Purchaser receives a request for additional information or
documentary material prior thereto. If within such 15 calendar day waiting
period either the FTC or the Antitrust Division were to request additional
information or documentary material from the Purchaser, the waiting period
with respect to the Offer and the Merger would be extended for an additional
period of 10 calendar days following the date of substantial compliance with
such request by the Purchaser. Only one extension of the waiting period
pursuant to a request for additional information is authorized by the rules
promulgated under the HSR Act. Thereafter, the waiting period could be
extended only by court order or with the consent of the Purchaser. The
additional 10 calendar day waiting period may be terminated sooner by the FTC
or the Antitrust Division.

   The FTC and the Antitrust Division frequently scrutinize the legality under
the antitrust laws of transactions such as the acquisition of Shares by Merger
Sub pursuant to the Offer and the Merger. At any time before or after Merger
Sub's purchase of Shares, the FTC or the Antitrust Division could take such
action under the antitrust laws as either deems necessary or desirable in the
public interest, including seeking to enjoin the purchase of Shares pursuant
to the Offer and the Merger, the divestiture of Shares purchased pursuant to
the Offer or the divestiture of substantial assets of the Purchaser, Merger
Sub, the Company or any of their respective subsidiaries or affiliates.
Pursuant to the Merger Agreement, the Purchaser and Merger Sub have agreed
that they will take all necessary actions to comply with any second request
from the Antitrust Division, but will not be required to agree to, or proffer
to, divest or hold separate any assets or any portion of any business of the
Purchaser, Merger Sub, or the Company or any of their respective subsidiaries
or oppose or take actions with respect to the defense of any lawsuit or
proceeding challenging the Merger Agreement or the transactions contemplated
thereby in connection with any competition laws. Private parties as well as
state attorneys general may also bring legal actions under the antitrust laws
under certain circumstances. See Section 13.

   Based upon an examination of publicly available information relating to the
businesses in which the Company is engaged, Merger Sub believes that the
acquisition of Shares pursuant to the Offer and the Merger should not violate
the applicable antitrust laws. Nevertheless, there can be no assurance that a
challenge to the Offer and the Merger on antitrust grounds will not be made,
or, if such challenge is made, what the result will be. See Section 13.

   Foreign Approvals. According to publicly available information, the Company
conducts business in a number of other foreign countries and jurisdictions. In
connection with the acquisition of the Shares pursuant to the Offer or the
Merger, the laws of certain of those foreign countries and jurisdictions may
require the filing of information with, or the obtaining of the approval or
consent of, governmental authorities in such countries and jurisdictions. The
governments in such countries and jurisdictions might attempt to impose
additional conditions on the Company's operations conducted in such countries
and jurisdictions as a result of the acquisition of the Shares pursuant to the
Offer or the Merger. If such approvals or consents are found to be required,
the parties intend to make the appropriate filings and applications. In the
event such a filing or application is made for the requisite foreign approvals
or consents, there can be no assurance that such approvals or consents will be
granted and, if such approvals or consents are received, there can be no
assurance as to the date of such approvals or consents. In addition, there can
be no assurance that Merger Sub will be able to cause the Company or its
subsidiaries to satisfy or comply with such laws or that compliance or
noncompliance will not have adverse consequences for the Company or any
subsidiary after purchase of the Shares pursuant to the Offer or the Merger.

15. Fees and Expenses

   Except as set forth below, the Purchaser will not pay any fees or
commissions to any broker, dealer or other person for soliciting tenders of
Shares pursuant to the Offer.

   Morgan Stanley is acting as Dealer Manager in connection with the Offer and
has provided certain financial advisory services to the Purchaser in
connection with the acquisition of the Company. The Purchaser has agreed to
pay Morgan Stanley reasonable and customary compensation for such services.
The Purchaser has also agreed to reimburse Morgan Stanley for all out-of-
pocket expenses incurred by Morgan Stanley, including fees and expenses of
legal counsel and to indemnify Morgan Stanley against certain liabilities and
expenses in connection with its engagement, including certain liabilities
under federal securities laws.

   The Purchaser has retained Georgeson Shareholder Communications Inc. to act
as the Information Agent and National City Bank to act as the Depositary in
connection with the Offer. The Information Agent may contact holders of Shares
by mail, telephone, telex, facsimile, telegraph and personal interview and may
request brokers, dealers, commercial banks, trust companies and other nominees
to forward the Offer materials to beneficial owners. The Information Agent and
the Depositary each will receive reasonable and customary compensation for
their services, will be reimbursed for certain reasonable out-of-pocket
expenses and will be indemnified against certain liabilities and expenses in
connection therewith, including certain liabilities under the federal
securities laws.

16. 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 such jurisdiction. However, Merger Sub
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 such
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 Merger Sub by one or more registered brokers or
dealers that are licensed under the laws of such jurisdiction.

   The Purchaser and Merger Sub have filed with the SEC a Schedule TO,
together with exhibits, pursuant to Rule 14d-3 of the General Rules and
Regulations under the Exchange Act, furnishing certain additional information
with respect to the Offer, and may file amendments thereto. Such Schedule TO
and any amendments thereto, including exhibits, may be examined and copies may
be obtained from the office of the SEC in the same manner as described in
Section 8 with respect to information concerning the Company, except that
copies will not be available at the regional offices of the SEC.

   No person has been authorized to give any information or to make any
representation on behalf of the Purchaser or Merger Sub not contained in this
Offer to Purchase or in the Letter of Transmittal and, if given or made, any
such information or representation must not be relied upon as having been
authorized.

   Neither the delivery of the Offer to Purchase nor any purchase pursuant to
the Offer shall under any circumstances create any implication that there has
been no change in the affairs of the Purchaser, Merger Sub, the Company or any
of their respective subsidiaries since the date as of which information is
furnished or the date of this Offer to Purchase.
