AGREEMENT AND UNANIMOUSLY RECOMMENDS THAT THE COMPANY'S STOCKHOLDERS ACCEPT
THE OFFER AND TENDER THEIR SHARES PURSUANT TO THE OFFER.
 
  The Offer is being made pursuant to an Agreement and Plan of Merger (the
"Merger Agreement"), dated as of March 3, 1998, among the Company, Purchaser
and the Merger Sub, pursuant to which, after the completion of the Offer, the
Merger Sub will be merged with and into the Company (the "Merger") and each
issued and outstanding Share (other than Shares owned by Purchaser, the Merger
Sub or any other subsidiary of Purchaser (collectively, the "Purchaser
Companies") or Shares that are held by stockholders exercising appraisal
rights ("Dissenting Stockholders") pursuant to Section 262 of the Delaware
General Corporation Law (the "DGCL")), shall, by virtue of the Merger and
without any action on the part of the holder thereof, be converted into the
right to receive, without interest, an amount in cash equal to $22.00 (the
"Merger Consideration"). As a result of the Merger, the Company (sometimes
referred to herein as the "Surviving Corporation") will become a wholly owned
subsidiary of Purchaser.
 
  According to the Company, as of February 26, 1998 there were 8,068,665
Shares outstanding and there were 919,150 Shares reserved for issuance under
then-current outstanding stock options pursuant to the Company's stock option
and incentive plans.

  THIS OFFER TO PURCHASE AND THE RELATED LETTER OF TRANSMITTAL CONTAIN
IMPORTANT INFORMATION WHICH SHOULD BE READ IN THEIR ENTIRETY BEFORE ANY
DECISION IS MADE WITH RESPECT TO THE OFFER.
 
1. TERMS OF THE OFFER.
 
  On the terms and subject to the conditions set forth in the Offer (including
the terms and conditions set forth in Section 13 (the "Offer Conditions") and,
if the Offer is extended or amended, the terms and conditions of such
extension or amendment), the Merger Sub will accept for payment, and pay for,
any and all Shares validly tendered on or prior to the Expiration Date (as
defined herein) and not withdrawn as permitted by Section 4. The term
"Expiration Date" means 12:00 Midnight, New York City time, on April 2, 1998,
unless and until the Merger Sub shall, in its sole discretion, have extended
the period for which the Offer is open, in which event the term "Expiration
Date" shall mean the latest time and date on which the Offer, as so extended
by the Merger Sub, shall expire.
 
  Rights are presently evidenced by the certificates for the Common Stock and
the tender by a stockholder of his shares of Common Stock will also constitute
a tender of the associated Rights. Pursuant to the Offer, no separate payment
will be made by the Merger Sub for the Rights pursuant to the Offer. Pursuant
to the Merger Agreement, the Board of Directors of the Company, at its meeting
on March 2, 1998, took all necessary action under the Rights Agreement to
provide that the execution of the Merger Agreement and the consummation of the
transactions contemplated thereby will not cause (i) the Merger Sub and/or
Purchaser to become an Acquiring Person (as defined herein) or (ii) a
Distribution Date (as defined herein) or a Stock Acquisition Date (as such
term is defined in the Rights Agreement) to occur, irrespective of the number
of Shares acquired pursuant to the Offer. See Section 11.
 
  Subject to the applicable rules and regulations of the Securities and
Exchange Commission (the "SEC"), the Merger Sub expressly reserves the right,
in its sole discretion, at any time or from time to time, to extend the period
of time during which the Offer is open by giving oral or written notice of
such extension to the Depositary. During any such extension, all Shares
previously tendered and not withdrawn will remain subject to the Offer,
subject to the right of a tendering stockholder to withdraw such stockholder's
Shares. See Section 4. Subject to the applicable regulations of the SEC, the
Merger Sub also expressly reserves the right, in its sole discretion, at any
time or from time to time, (i) to delay acceptance for payment of or,
regardless of whether such Shares were theretofore accepted for payment,
payment for any tendered Shares or to terminate or amend the Offer as to any
Shares not then paid for, on the occurrence of any of the conditions specified
in Section 13 and (ii) to waive any condition or otherwise amend the Offer in
any respect, by giving oral or written notice of such delay, termination or
amendment to the Depositary and by making a public announcement thereof. If
the Merger Sub accepts any Shares for payment pursuant to the terms of the
Offer, it will accept for payment all Shares validly tendered prior to the
Expiration Date and not withdrawn, and, subject to (i) above, will promptly
pay for all Shares so accepted for payment. The Merger Sub confirms that its
reservation of the right to delay payment for Shares which it has accepted for
payment is limited by Rule 14e-1(c) under the Securities Exchange Act of 1934,
as amended (the "Exchange Act"), which requires that a tender offeror pay the
consideration offered or return the tendered securities promptly after the
termination or withdrawal of a tender offer.
 
  Any extension, delay, termination or amendment of the Offer will be followed
as promptly as practicable by public announcement thereof, such announcement
in the case of an extension to be issued no later than 9:00 A.M., New York
City time, on the next business day after the previously scheduled Expiration
Date. Subject to applicable law (including Rules 14d-4(c) and 14d-6(d) under
the Exchange Act, which require that any material change in the information
published, sent or given to stockholders in connection with the Offer be
promptly disseminated to stockholders in a manner reasonably designed to
inform stockholders of such change) and without limiting the manner in which
the Merger Sub may choose to make any public announcement, the Merger Sub
shall have no obligation to publish, advertise or otherwise communicate any
such public announcement other than by issuing a press release or other
announcement.
 
                                       2
<PAGE>
 
  The Merger Sub confirms that if it makes a material change in the terms of
the Offer or the information concerning the Offer, or if it waives a material
condition of the Offer, the Merger Sub will extend the Offer to the extent
required by Rules 14d-4(c) and 14d-6(d) under the Exchange Act.
 
  If, prior to the Expiration Date, the Merger Sub, in its sole discretion,
shall decrease the percentage of Shares being sought or the consideration
offered to holders of Shares, such decrease shall be applicable to all holders
whose Shares are accepted for payment pursuant to the Offer and, if at the
time notice of any increase or decrease is first published, sent or given to
holders of Shares, the Offer is scheduled to expire at any time earlier than
the tenth business day from and including the date that such notice is first
so published, sent or given, the Offer will be extended until the expiration
of such ten business day period. For purposes of the Offer, a "business day"
means any day other than a Saturday, Sunday or federal holiday and consists of
the time period from 12:01 A.M. through 12:00 Midnight, New York City time.
 
  The Offer is being mailed to holders of Shares from a list provided to the
Merger Sub by the Company.
 
2. ACCEPTANCE FOR PAYMENT AND PAYMENT FOR SHARES.
 
  On the terms and subject to the conditions of the Offer (including the Offer
Conditions and, if the Offer is extended or amended, the terms and conditions
of any such extension or amendment), the Merger Sub will accept for payment,
and will pay for, Shares validly tendered and not withdrawn as promptly as
practicable after the later of (i) the expiration or termination of the
waiting period under the HSR Act applicable to the purchase of Shares pursuant
to the Offer, and any similar waiting periods under any foreign statutes or
regulations that are applicable to the Offer and the Merger having expired or
been terminated and the date all required filings, consents, approvals, and
authorizations of any Governmental Entity (as defined in the Merger Agreement)
shall have been obtained on terms satisfactory to Purchaser in its reasonable
discretion and (ii) the Expiration Date, if at the time of the later of the
occurrence of (i) and (ii) above, the Minimum Condition (as defined herein)
has been satisfied or waived, provided that the Merger Sub reserves the right,
in its sole discretion, to extend the Offer from time to time notwithstanding
the prior satisfaction of the Offer Conditions. See Sections 13 and 15.
Purchaser filed a Notification and Report Form under the HSR Act on March 4,
1998, and, accordingly, unless earlier terminated or extended by a request for
additional information, the waiting period under the HSR Act is scheduled to
expire at 11:59 p.m., New York City time, on March 19, 1998. See Section 15.
In addition, subject to applicable rules of the SEC, the Merger Sub expressly
reserves the right to delay acceptance for payment of or payment for Shares in
order to comply, in whole or in part, with any applicable law. See Section 13.
In all cases, payment for Shares tendered and accepted for payment pursuant to
the Offer will be made only after timely receipt by the Depositary of
certificates for such Shares (or a confirmation of a book-entry transfer of
such Shares (a "Book-Entry Confirmation") into the Depositary's account at The
Depository Trust Company or the Philadelphia Depository Trust Company (each a
"Book-Entry Transfer Facility" and, collectively, the "Book-Entry Transfer
Facilities")), a properly completed and duly executed Letter of Transmittal
(or facsimile thereof) and any other required documents.
 
  For purposes of the Offer, the Merger Sub will be deemed to have accepted
for payment Shares validly tendered and not withdrawn as, if and when the
Merger Sub gives oral or written notice to the Depositary of its acceptance
for payment of such Shares pursuant to the Offer. Payment for Shares accepted
for payment pursuant to the Offer will be made by deposit of the purchase
price therefor with the Depositary, which will act as agent for the tendering
stockholders for the purpose of receiving payments from the Merger Sub and
transmitting such payments to the tendering stockholders. UNDER NO
CIRCUMSTANCES WILL INTEREST ON THE PURCHASE PRICE FOR SHARES BE PAID,
REGARDLESS OF ANY DELAY IN MAKING SUCH PAYMENT.
 
  If any tendered Shares are not accepted for payment pursuant to the terms
and conditions of the Offer for any reason, or if certificates are submitted
for more Shares than are tendered, certificates for such unpurchased Shares
will be returned, without expense to the tendering stockholder (or, in the
case of Shares tendered by book-entry transfer of such Shares into the
Depositary's account at a Book-Entry Transfer Facility pursuant to the
 
                                       3
<PAGE>
 
procedures set forth in Section 3, such Shares will be credited to an account
maintained with such Book-Entry Transfer Facility), as soon as practicable
following expiration or termination of the Offer.
 
  The Merger Sub reserves the right to transfer or assign in whole or in part
from time to time to one or more direct or indirect subsidiaries of Purchaser
the right to purchase all or any portion of the Shares tendered pursuant to
the Offer, but any such transfer or assignment will not relieve the Merger Sub
of its obligations under the Offer and will in no way prejudice the rights of
tendering stockholders to receive payment for Shares validly tendered and
accepted for payment pursuant to the Offer.
 
3. PROCEDURE FOR TENDERING SHARES.
 
  Valid Tender. To tender Shares pursuant to the Offer, either (a) a properly
completed and duly executed Letter of Transmittal (or a facsimile thereof) in
accordance with the instructions of the Letter of Transmittal, with any
required signature guarantees, certificates for Shares to be tendered, and any
other documents required by the Letter of Transmittal, must be received by the
Depositary prior to the Expiration Date at one of its addresses set forth on
the back cover of this Offer to Purchase, (b) such Shares must be delivered
pursuant to the procedures for book-entry transfer described below (and a
Book-Entry Confirmation of such delivery received by the Depositary, including
an Agent's Message (as defined herein) if the tendering stockholder has not
delivered a Letter of Transmittal), prior to the Expiration Date, or (c) the
tendering stockholder must comply with the guaranteed delivery procedures set
forth below. The term "Agent's Message" means a message, transmitted by a
Book-Entry Transfer Facility to, and received by, the Depositary and forming a
part of a Book-Entry Confirmation, which states that such Book-Entry Transfer
Facility has received an express acknowledgment from the participant in such
Book-Entry Transfer Facility tendering the Shares and, if applicable, Rights
which are the subject of such Book-Entry Confirmation, that such participant
has received and agrees to be bound by the terms of the Letter of Transmittal
and that the Merger Sub may enforce such agreement against the participant.
 
  Pursuant to the Rights Agreement, until the close of business on the
Distribution Date, the Rights will be transferred with and only with the
certificates for Shares and the surrender for transfer of any certificates for
Common Stock will also constitute the transfer of the Rights associated with
the Shares represented by such certificate. Pursuant to the Rights Agreement,
the Company has taken all necessary action to ensure that no Distribution Date
will occur by reason of the commencement or consummation of the Offer or any
of the transactions contemplated by the Merger Agreement. See Section 11.
 
  If separate certificates representing the Rights are issued to holders of
Shares prior to the time a holder's Shares are tendered pursuant to the Offer,
certificates representing a number of Rights equal to the number of shares of
Common Stock tendered must be delivered to the Depositary, or, if available, a
Book-Entry Confirmation received by the Depositary with respect thereto, in
order for such shares of Common Stock to be validly tendered. If the
Distribution Date occurs and separate certificates representing the Rights are
not distributed prior to the time Shares are tendered pursuant to the Offer,
Rights may be tendered prior to a stockholder receiving the certificates for
Rights by use of the guaranteed delivery procedure described below. A tender
of shares of Common Stock constitutes an agreement by the tendering
stockholder to deliver certificates representing all Rights formerly
associated with the number of shares of Common Stock tendered pursuant to the
Offer to the Depositary prior to expiration of the period permitted by such
guaranteed delivery procedures for delivery of certificates for, or a Book-
Entry Confirmation with respect to, Rights (the "Rights Delivery Period").
However, after expiration of the Rights Delivery Period, the Merger Sub may
elect to reject as invalid a tender of shares of Common Stock with respect to
which certificates for, or a Book-Entry Confirmation with respect to, the
number of Rights required to be tendered with such Common Stock have not been
received by the Depositary. Nevertheless, the Merger Sub will be entitled to
accept for payment shares of Common Stock tendered by a stockholder prior to
receipt of the certificates for the Rights required to be tendered with such
shares of Common Stock, or a Book-Entry Confirmation with respect to such
Rights, and either (a) subject to complying with applicable rules and
regulations of the SEC, withhold payment for such shares of Common Stock
pending receipt of the certificates for, or a Book-Entry Confirmation with
respect to, such Rights or (b) make
 
                                       4
<PAGE>
 
payment for shares of Common Stock accepted for payment pending receipt of the
certificates for, or a Book-Entry Confirmation with respect to, such Rights in
reliance upon the agreement of a tendering stockholder to deliver Rights and
such guaranteed delivery procedures. Any determination by the Merger Sub to
make payment for shares of Common Stock in reliance upon such agreement and
such guaranteed delivery procedures or, after expiration of the Rights
Delivery Period, to reject a tender as invalid will be made in the sole and
absolute discretion of the Merger Sub.
 
  Book-Entry Delivery. The Depositary will establish accounts with respect to
the Shares at the Book-Entry Transfer Facilities for purposes of the Offer
within two business days after the date of this Offer to Purchase. Any
financial institution that is a participant in any of the Book-Entry Transfer
Facilities' systems may make a book-entry transfer of Shares by causing a
Book-Entry Transfer Facility to transfer such Shares into the Depositary's
account in accordance with such Book-Entry Transfer Facility's procedures for
such transfer. Although delivery of Shares may be effected through book-entry
transfer, either the Letter of Transmittal (or facsimile thereof), properly
completed and duly executed, together with any required signature guarantees,
or an Agent's Message in lieu of the Letter of Transmittal, and any other
required documents, must, in any case, be transmitted to and received by the
Depositary by the Expiration Date at one of its addresses set forth on the
back cover of this Offer to Purchase, or the tendering stockholder must comply
with the guaranteed delivery procedures described below. If the Distribution
Date occurs, the Depositary will also make a request to establish an account
with respect to the Rights at each of the Book-Entry Transfer Facilities, but
no assurance can be given that book-entry transfer of Rights will be
available. If book-entry transfer of Rights is available, the foregoing book-
entry transfer procedures will also apply to Rights. If book-entry transfer of
Rights is not available and the Distribution Date occurs, a tendering
stockholder will be required to tender Rights by means of physical delivery of
certificates for Rights to the Depositary (in which event references in this
Offer to Purchase to Book-Entry Confirmations with respect to Rights will be
inapplicable). DELIVERY OF DOCUMENTS TO A BOOK-ENTRY TRANSFER FACILITY IN
ACCORDANCE WITH SUCH BOOK-ENTRY TRANSFER FACILITY'S PROCEDURES DOES NOT
CONSTITUTE DELIVERY TO THE DEPOSITARY.
 
  THE METHOD OF DELIVERY OF SHARES, RIGHTS, THE LETTER OF TRANSMITTAL AND ALL
OTHER REQUIRED DOCUMENTS, INCLUDING DELIVERY THROUGH ANY BOOK-ENTRY TRANSFER
FACILITY, IS AT THE ELECTION AND RISK OF THE TENDERING STOCKHOLDER. SHARES
WILL BE DEEMED DELIVERED ONLY WHEN ACTUALLY RECEIVED BY THE DEPOSITARY
(INCLUDING, IN THE CASE OF A BOOK-ENTRY TRANSFER, BY BOOK-ENTRY CONFIRMATION).
IF DELIVERY IS BY MAIL, IT IS RECOMMENDED THAT THE STOCKHOLDER USE PROPERLY
INSURED REGISTERED MAIL WITH RETURN RECEIPT REQUESTED. IN ALL CASES,
SUFFICIENT TIME SHOULD BE ALLOWED TO ENSURE TIMELY DELIVERY.
 
  Signature Guarantees. Except as otherwise provided below, all signatures on
a Letter of Transmittal must be guaranteed by a financial institution
(including most commercial banks, savings and loan associations and brokerage
houses) that is a participant in the Security Transfer Agents Medallion
Program, the New York Stock Exchange Medallion Signature Guarantee Program or
the Stock Exchange Medallion Program (an "Eligible Institution"). Signatures
on a Letter of Transmittal need not be guaranteed (a) if the Letter of
Transmittal is signed by the registered holders (which term, for purposes of
this section, includes any participant in any of the Book-Entry Transfer
Facilities' systems whose name appears on a security position listing as the
owner of the Shares or Rights) of Shares (or Rights, if applicable) and such
registered holder has not completed the box entitled "Special Payment
Instructions" or the box entitled "Special Delivery Instructions" on the
Letter of Transmittal, or (b) if such Shares and Rights are tendered for the
account of an Eligible Institution. See Instructions 1 and 5 of the Letter of
Transmittal. If the certificates for Shares or Rights are registered in the
name of a person other than the signer of the Letter of Transmittal, or if
payment is to be made or certificates for Shares or Rights not tendered or not
accepted for payment are to be returned to a person other than the registered
holder of the certificates surrendered, then the tendered certificates must be
endorsed or accompanied by appropriate stock powers, in either case signed
exactly as the name or names of the registered holders or owners
 
                                       5
<PAGE>
 
appear on the certificates, with the signatures on the certificates or stock
powers guaranteed as described above. See Instructions 1 and 5 of the Letter
of Transmittal.
 
  Guaranteed Delivery. A stockholder who desires to tender Shares (or Rights,
if applicable) pursuant to the Offer and whose certificates for Shares (or
Rights, if applicable) are not immediately available (including because
certificates for Rights have not yet been distributed by the Rights Agent), or
who cannot comply with the procedure for book-entry transfer on a timely
basis, or who cannot deliver all required documents to the Depositary prior to
the Expiration Date, may tender such Shares (and/or Rights, if applicable) by
following all of the procedures set forth below:
 
    (i) such tender is made by or through an Eligible Institution;
 
    (ii) a properly completed and duly executed Notice of Guaranteed
  Delivery, substantially in the form provided by the Merger Sub, is received
  by the Depositary (as provided below) prior to the Expiration Date; and
 
    (iii) the certificates for all tendered Shares and/or Rights, in proper
  form for transfer (or a Book-Entry Confirmation with respect to all such
  Shares and/or Rights), 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 in
  lieu of the Letter of Transmittal), and any other required documents, are
  received by the Depositary (a) in the case of Shares, within three trading
  days after the date of execution of such Notice of Guaranteed Delivery or
  (b) in the case of Rights, within a period ending on the later of (1) three
  trading days after the date of execution of such Notice of Guaranteed
  Delivery or (2) three trading days after the date certificates for Rights
  are distributed to stockholders by the Rights Agent. A "trading day" is any
  day on which the New York Stock Exchange (the "NYSE") is open for business.
 
  The Notice of Guaranteed Delivery may be delivered by hand to the Depositary
or transmitted by telegram, facsimile transmission or mail to the Depositary
and must include a guarantee by an Eligible Institution in the form set forth
in such Notice of Guaranteed Delivery.
 
  Other Requirements. Notwithstanding any 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 (a) certificates for (or a timely
Book-Entry Confirmation with respect to) such Shares and, if the Distribution
Date occurs, certificates for (or a timely Book-Entry Confirmation, if
available, with respect to) the associated Rights, unless the Merger Sub
elects to make payment for such shares of Common Stock pending receipt of the
certificates for, or a Book-Entry Confirmation with respect to, such Rights as
described above, (b) a Letter of Transmittal (or facsimile thereof), properly
completed and duly executed, with any required signature guarantees (or, in
the case of a book-entry transfer, an Agent's Message in lieu of the Letter of
Transmittal), and (c) any other documents required by the Letter of
Transmittal. Accordingly, tendering stockholders may be paid at different
times depending upon when certificates for Shares (or Rights, if applicable)
or Book-Entry Confirmations with respect to Shares (or Rights, if available)
are actually received by the Depositary. UNDER NO CIRCUMSTANCES WILL INTEREST
ON THE PURCHASE PRICE OF THE SHARES BE PAID BY THE MERGER SUB, REGARDLESS OF
ANY EXTENSION OF THE OFFER OR ANY DELAY IN MAKING SUCH PAYMENT.
 
  Tender Constitutes an Agreement. The valid tender of Shares and, if
applicable, Rights pursuant to one of the procedures described above will
constitute a binding agreement between the tendering stockholder and the
Merger Sub on the terms and subject to the conditions of the Offer.
 
  Appointment. By executing a Letter of Transmittal as set forth above, the
tendering stockholder irrevocably appoints designees of the Merger Sub as such
stockholder's proxies, each with full power of substitution, to the full
extent of such stockholder's rights with respect to the Shares tendered by
such stockholder and accepted for payment by the Merger Sub and with respect
to any and all cash dividends, distributions, rights, other Shares or other
securities issued or issuable in respect of such Shares on or after the date
of this Offer to Purchase. All such proxies will be considered coupled with an
interest in the tendered Shares, including the associated Rights. Such
appointment is effective when, and only to the extent that, the Merger Sub
deposits the
 
                                       6
<PAGE>
 
payment for such Shares with the Depositary. Upon the effectiveness of such
appointment, all prior powers of attorney, proxies and consents given by such
stockholder will be revoked, and no subsequent powers of attorney, proxies and
consents may be given (and, if given, will not be deemed effective). The
Merger Sub's designees will, with respect to the Shares for which the
appointment is effective, be empowered to exercise all voting and other rights
of such stockholder as they, in their sole discretion, may deem proper at any
annual, special or adjourned meeting of the stockholders of the Company, by
written consent in lieu of any such meeting or otherwise. The Merger Sub
reserves the right to require that, in order for Shares to be deemed validly
tendered, immediately upon the Merger Sub's payment for such Shares, the
Merger Sub must be able to exercise full voting rights with respect to such
Shares.
 
  Determination of Validity. All questions as to the validity, form,
eligibility (including time of receipt) and acceptance of any tender of Shares
or Rights will be determined by the Merger Sub in its sole discretion, which
determination will be final and binding. The Merger Sub reserves the absolute
right to reject any and all tenders determined by it not to be in proper form
or the acceptance for payment of or payment for which may, in the opinion of
the Merger Sub's counsel, be unlawful. The Merger Sub also reserves the
absolute right to waive any defect or irregularity in the tender of any Shares
or Rights of any particular stockholder whether or not similar defects or
irregularities are waived in the case of other stockholders. No tender of
Shares or Rights will be deemed to have been validly made until all defects
and irregularities relating thereto have been cured or waived. None of the
Merger Sub, the Depositary, the Information Agent, the Dealer Manager or any
other person will be under any duty to give notification of any defects or
irregularities in tenders or incur any liability for failure to give any such
notification. The Merger Sub's interpretation of the terms and conditions of
the Offer (including the Letter of Transmittal and Instructions thereto) will
be final and binding.
 
  Backup Withholding. In order to avoid "backup withholding" of Federal income
tax on payments of cash pursuant to the Offer, a stockholder surrendering
Shares in the Offer must, unless an exemption applies, provide the Depositary
with such stockholder's correct taxpayer identification number ("TIN") on a
Substitute Form W-9 and certify under penalties of perjury that such TIN is
correct and that such stockholder is not subject to backup withholding. If a
stockholder does not provide such stockholder's correct TIN or fails to
provide the certifications described above, the Internal Revenue Service (the
"IRS") may impose a penalty on such stockholder and payment of cash to such
stockholder pursuant to the Offer may be subject to backup withholding of 31%.
All stockholders surrendering Shares pursuant to the Offer should complete and
sign the main signature form and the Substitute Form W-9 included as part of
the Letter of Transmittal to provide the information and certification
necessary to avoid backup withholding (unless an applicable exemption exists
and is proved in a manner satisfactory to the Merger Sub and the Depositary).
Certain stockholders (including, among others, all corporations and certain
foreign individuals and entities) are not subject to backup withholding. Non-
corporate foreign stockholders should complete and sign the main signature
form and a Form W-8, Certificate of Foreign Status, a copy of which may be
obtained from the Depositary, in order to avoid backup withholding. See
Instruction 9 to the Letter of Transmittal.
 
4. RIGHTS OF WITHDRAWAL.
 
  Tenders of Shares made pursuant to the Offer are irrevocable except that
Shares tendered pursuant to the Offer may be withdrawn at any time prior to
the Expiration Date and, unless theretofore accepted for payment by the Merger
Sub pursuant to the Offer, may also be withdrawn at any time after May 4,
1998.
 
  For a withdrawal to be effective, a written, telegraphic, telex 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 having
tendered the Shares to be withdrawn, the number of Shares to be withdrawn and
the names in which the certificate(s) evidencing the Shares to be withdrawn
are registered, if different from that of the person who tendered such Shares.
The signature(s) on the notice of withdrawal must be guaranteed by an Eligible
Institution, unless such Shares have been tendered for the account of any
Eligible Institution. If Shares have been tendered pursuant to the procedures
for book-entry tender as set forth in Section 3, any notice of withdrawal must
specify the name and number of the account at
 
                                       7
<PAGE>
 
the Book-Entry Transfer Facility to be credited with the withdrawn Shares. If
certificates for Shares to be withdrawn have been delivered or otherwise
identified to the Depositary, the name of the registered holder and the serial
numbers of the particular certificates evidencing the Shares to be withdrawn
must also be furnished to the Depositary as aforesaid prior to the physical
release of such certificates. All questions as to the form and validity
(including time of receipt) of any notice of withdrawal will be determined by
the Merger Sub, in its sole discretion, which determination shall be final and
binding. None of Purchaser, the Merger Sub, the Dealer Manager, the
Depositary, the Information Agent, or any other person will be under any duty
to give notification of any defects or irregularities in any notice of
withdrawal or incur any liability for failure to give such notification.
Withdrawals of tenders of Shares may not be rescinded, and any Shares properly
withdrawn will be deemed not to have been validly tendered for purposes of the
Offer. However, withdrawn Shares may be retendered by following one of the
procedures described in Section 3 at any time prior to the Expiration Date.
 
  If the Merger Sub extends the Offer, is delayed in its acceptance for
payment of Shares, or is unable to accept for payment Shares pursuant to the
Offer, for any reason, then, without prejudice to the Merger Sub's rights
under this Offer, the Depositary may, nevertheless, on behalf of the Merger
Sub, retain tendered Shares, and such Shares may not be withdrawn except to
the extent that tendering stockholders are entitled to withdrawal rights as
set forth in this Section 4.
 
5. CERTAIN FEDERAL INCOME TAX CONSEQUENCES OF THE OFFER.
 
  Sales of Shares pursuant to the Offer and the exchange of Shares for cash
pursuant to the Merger will be taxable transactions for Federal income tax
purposes and may also be taxable under applicable state, local and other tax
laws. For Federal income tax purposes, a stockholder whose Shares are
purchased pursuant to the Offer or who receives cash as a result of the Merger
will realize gain or loss equal to the difference between the adjusted basis
of the Shares sold or exchanged and the amount of cash received therefor. Such
gain or loss will be capital gain or loss if the Shares are held as capital
assets by the stockholder and generally will be long-term capital gain or loss
for stock held for more than one year. Long-term capital gain of a non-
corporate stockholder is generally subject to a maximum tax rate of 28% in
respect of property held for more than one year and to a maximum rate of 20%
in respect of property held in excess of 18 months.
 
  THE INCOME TAX DISCUSSION SET FORTH ABOVE IS INCLUDED FOR GENERAL
INFORMATION ONLY AND MAY NOT BE APPLICABLE TO STOCKHOLDERS IN SPECIAL
SITUATIONS SUCH AS STOCKHOLDERS WHO RECEIVED THEIR SHARES UPON THE EXERCISE OF
EMPLOYEE STOCK OPTIONS OR OTHERWISE AS COMPENSATION AND STOCKHOLDERS WHO ARE
NOT UNITED STATES PERSONS. STOCKHOLDERS SHOULD CONSULT THEIR OWN TAX ADVISORS
WITH RESPECT TO THE SPECIFIC TAX CONSEQUENCES TO THEM OF THE OFFER AND THE
MERGER, INCLUDING THE APPLICATION AND EFFECT OF FEDERAL, STATE, LOCAL, FOREIGN
OR OTHER TAX LAWS.
 
6. PRICE RANGE OF SHARES; DIVIDENDS.
 
  The Shares are traded on the NYSE under the symbol "APK". Prior to October
1, 1997, the Shares were traded on The Nasdaq Stock Market's National Market

  The Rights trade together with the Common Stock. On March 3, 1998, the last
full trading day prior to the public announcement of the terms of the Offer
and the Merger, the quoted closing price on the NYSE was $17.69 per Share. On
March 5, 1998, the last full trading day prior to commencement of the Offer,
the reported closing price on the NYSE was $21.63 per Share. STOCKHOLDERS ARE
URGED TO OBTAIN A CURRENT MARKET QUOTATION FOR THE SHARES.
 
7. EFFECT OF THE OFFER ON MARKET FOR THE SHARES, STOCK EXCHANGE LISTING, AND
EXCHANGE ACT REGISTRATION.
 
  Market for Shares. The purchase of Shares by the Merger Sub pursuant to the
Offer will reduce the number of Shares that might otherwise trade publicly and
may reduce the number of holders of Shares, which could adversely affect the
liquidity and market value of the remaining Shares held by the public.
 
  Stock Quotation. The Shares are quoted on the NYSE. According to the NYSE's
published guidelines, the NYSE would consider delisting the shares of Common
Stock if, among other things, the number of record holders of at least 100
shares of Common Stock should fall below 1,200, the number of publicly held
shares of Common Stock (exclusive of holdings of officers and directors of the
Company and their immediate families and other concentrated holdings of 10% or
more ("NYSE Excluded Holdings'')) should fall below 600,000, or the aggregate
market value of the publicly held shares of Common Stock (exclusive of NYSE
Excluded Holdings) should fall below $5,000,000. According to information
furnished to Purchaser by the Company, as of the close of business on February
26, 1998, there were 3,600 holders of record of shares of Common Stock not
including beneficial holders of Common Stock held in street name, and there
were 8,068,665 Shares outstanding. If the Common Stock were to be delisted,
the associated Rights would be delisted as well.
 
  If the NYSE were to delist the Shares, the market for the Shares could
therefor be adversely affected. It is possible that the Shares would be traded
or quoted on other securities exchanges or in the over-the-counter market, and
that price quotations would be reported by such exchanges, or other sources.
The extent of the public market for the shares of Common Stock and associated
Rights and the availability of such quotations would, however, depend upon the
number of stockholders and/or the aggregate market value of the shares of
Common Stock and associated Rights remaining at such time, the interest in
maintaining a market in the shares of Common Stock and associated Rights on
the part of securities firms, the possible termination of registration of the
Shares under the Exchange Act and other factors.
 
  Margin Regulations. The shares of Common Stock are presently "margin
securities" under the regulations of the Board of Governors of the Federal
Reserve System (the "Federal Reserve Board"), which has the effect, among
other things, of allowing brokers to extend credit on the collateral of such
shares of Common Stock. Depending upon factors similar to those described
above regarding listing and market
 
                                       9
<PAGE>
 
quotations, the shares of Common Stock might no longer constitute "margin
securities" for the purposes of the Federal Reserve Board's margin regulations
in which event the shares of Common Stock would be ineligible as collateral
for margin loans made by brokers.
 
  Exchange Act Registration. The shares of Common Stock and associated Rights
are currently registered under the Exchange Act. Such registration may be
terminated by the Company upon application to the SEC if the outstanding
shares of Common Stock and associated Rights are not listed on a national
securities exchange and if there are fewer than 300 holders of record of
shares of Common Stock and associated Rights. Termination of registration of
the shares of Common Stock and associated Rights under the Exchange Act would
reduce the information required to be furnished by the Company to its
stockholders and to 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 requirement to furnish a proxy statement in connection with stockholders'
meetings pursuant to Section 14(a) and the related requirement to furnish an
annual report to stockholders, no longer applicable with respect to the shares
of Common Stock and Rights. 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 under the Securities Act of 1933, as
amended, may be impaired or eliminated. If registration of the shares of
Common Stock under the Exchange Act were terminated, the shares of Common
Stock would no longer be eligible for listing on the NYSE or for continued
inclusion on the Federal Reserve Board's list of "margin securities". The
Merger Sub intends to seek to cause the Company to apply for termination of
registration of the shares of Common Stock and associated Rights as soon as
possible after consummation of the Offer if the requirements for termination
of registration are met.

  Except as otherwise set forth herein, the information concerning the Company
contained in this Offer to Purchase has been taken from or based upon publicly
available documents and records on file with the SEC and other public sources
and is qualified in its entirety by reference thereto. Although Purchaser, the
Merger Sub, the Information Agent and the Dealer Manager have no knowledge
that would indicate that any statements contained herein based on such
documents and records are untrue, Purchaser, the Merger Sub, the Information
Agent and the Dealer Manager cannot take responsibility for the accuracy or
completeness of the information contained in such documents and records, or
for any failure by the Company to disclose events which may have occurred or
may affect the significance or accuracy of any such information but which are
unknown to Purchaser, the Merger Sub, the Information Agent or the Dealer
Manager.
 
  In the course of the discussions between Company management and Purchaser,
Purchaser was provided with certain financial information and projections
prepared by Company management. The projections indicate estimated primary
earnings per share for the Company of $1.12, $1.24 and $1.38, for 1998, 1999
and 2000, respectively.
 
                                      11

The Company has advised Purchaser that (i) it does not, as a matter of course,
make public forecasts as to future revenues or profits and (ii) the foregoing
projections were based on estimates and assumptions that are inherently
subject to significant economic and competitive uncertainties, all of which
are difficult to predict and many of which are beyond the Company's control.
Accordingly, there can be no assurance that the projected results can be
realized or that actual results will not be materially higher or lower than
those projected. 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. None of the Company, Purchaser
or the Merger Sub or their respective advisors assumes any responsibility for
the accuracy of the projections. The inclusion of the foregoing projections
should not be regarded as an indication that the Company, Purchaser, the
Merger Sub or any other person who received such information considers it an
accurate prediction of future events. Neither the Company nor Purchaser
intends to update, revise or correct such projections if they become
inaccurate (even in the short term).
 
  The Company is subject to the information and reporting requirements of the
Exchange Act and in accordance therewith is obligated to file reports and
other information with the SEC relating to its business, financial condition
and other matters. Information, as of particular dates, concerning the
Company's directors and officers, their remuneration, stock options granted to
them, the principal holders of the Company's securities, any material
interests of such persons in transactions with the Company and other matters
is required to be disclosed in proxy statements distributed to the Company's
stockholders and filed with the SEC. Such reports, proxy statements and other
information should be available for inspection at the public reference room at
the SEC's offices at 450 Fifth Street, N.W., Washington, DC 20549, and also
should be available for inspection and copying at the regional offices of the

  Statements Purchaser may publish, including those in this Offer to Purchase,
that are not strictly historical are "forward-looking" statements under the
safe harbor provisions of the Private Securities Litigation Reform Act of
1995. Although Purchaser believes the expectations reflected in such forward-
looking statements are based on reasonable assumptions, it can give no
assurance that its expectations will be realized. Forward-looking statements
involve known and unknown risks which may cause Purchaser's actual results and
corporate developments to differ materially from those expected. Factors that
could cause results and developments to differ materially from Purchaser's
expectations include, without limitation, changes in manufacturing and
shipment schedules, delays in completing plant construction and acquisitions,
currency exchange rates, new product and technology developments, competition
within each business segment, cyclicity of the markets for the products of a
major segment, litigation, significant cost variances, the effects of
acquisitions and divestitures, and other risks described from time to time in
Purchaser's SEC reports including quarterly reports on Form 10-Q, annual
reports on Form 10-K and reports on Form 8-K.

10. BACKGROUND OF THE OFFER; CONTACTS WITH THE COMPANY.
 
  In connection with the preparation of its 1998 strategic plan, in September
1997 Purchaser hired Beach Consulting Partners to provide certain management
consulting services, including reviewing Purchaser's strategic position and
opportunities for earnings growth in each of its lines of business. Purchaser
also engaged Wasserstein Perella & Co., Inc. ("Wasserstein Perella") on
November 14, 1997 to provide certain financial advisory services in connection
with the preparation of Purchaser's 1998 long term strategic plan.
 
  On November 19, 1997, Mr. Jackson received a telephone call from Mr. Hummer
in which Mr. Hummer inquired about Purchaser's interest in discussing a
possible acquisition of the Company. Mr. Jackson and Mr. Hummer agreed to meet
to discuss preliminarily a possible transaction between the two parties. The
meeting was scheduled for December 1, 1997 at the offices of Purchaser.
 
  In preparation for the December 1, 1997 meeting, Juan M. Bravo, the
President of Harbison-Walker Refractories Company ("H-W Refractories"), the
refractory subsidiary of Purchaser, traveled to the Company's headquarters in
Mexico, Missouri and met with representatives of the Company to discuss the
concept of merging the Company with Purchaser or a subsidiary of Purchaser.
 
  On December 1, 1997, Mr. Hummer and Michael B. Cooney, Senior Vice President
Law/Administration and Secretary of the Company, met with Mr. Jackson, Graham
L. Adelman, Senior Vice President, General Counsel and Secretary of Purchaser,
Mr. Bravo and Dirk H. Hilkmann, Vice President--Planning and Development of H-
W Refractories at Purchaser's offices in Dallas, Texas. At this meeting the
parties discussed the perceived benefits that would accrue from a combination
of the two companies. The parties also discussed a number of transaction
structuring issues on a preliminary basis. As the parties had not yet executed
a confidentiality agreement at this date, no proprietary information with
respect to the respective businesses was discussed and no nonpublic financial
information was exchanged. Both parties agreed that further discussions should
continue with respect to a possible business combination.
 
  On December 5, 1997, management of the Company selected Credit Suisse First
Boston Corporation ("Credit Suisse First Boston") as its financial advisor.
 
  Commencing on December 4, 1997, a number of telephone calls were exchanged
between management of the Company and management of Purchaser with respect to
the negotiation and execution of a confidentiality
 
                                      14

agreement between the parties. The definitive Confidentiality Agreement was
executed by the parties on December 12, 1997.
 
  At a December 17, 1997 meeting of the Purchaser's Board of Directors, Mr.
Jackson informed the Board regarding Purchaser's discussions to date with the
Company. Wasserstein Perella presented a preliminary analysis of a potential
acquisition of the Company in the context of a possible use of proceeds from
the proposed sale of Purchaser's Industrial Tool business.
 
  On January 7, 1998, Mr. Hummer, Mr. Cooney, John L. Kelsey, Vice President,
Refractory Marketing and Gary L. Roberts, Vice President and Chief Financial
Officer of the Company, met with Messrs. Jackson, Adelman, Bravo and Hilkmann
at the offices of Purchaser in Dallas, Texas. At this meeting the parties
discussed potential structures for a transaction. Purchaser advised the
Company at this meeting that its preferred structure for acquisition of the
Company was a complete acquisition of the Company for cash or an establishment
of a joint venture in which Purchaser would control at least 80% of the equity
interest. Mr. Jackson and Mr. Hummer also met privately to discuss personnel
and operational matters in the context of an acquisition transaction.
 
  At a meeting of the Board of Directors of Purchaser on January 18 and 19,
1998, management presented its proposed strategic plan. Beach Consulting
Partners made a presentation to the Board regarding the results of its
management consulting study and the proposed strategic plan and Wasserstein
Perella presented a valuation analysis relating to the proposed strategic
plan. After extensive discussion, the Board of Directors of Purchaser adopted
the proposed 1998 long term strategic plan and authorized management to pursue
a potential acquisition of the Company. Purchaser engaged Wasserstein Perella
effective January 18, 1998 to provide financial advisory services related to
the possible acquisition of the Company.
 
  Following the meeting and over the next several weeks, Purchaser made
various due diligence requests of the Company and conducted meetings with
respect to operational issues and tours of the Company's facilities.
Discussions were also held between representatives of Credit Suisse First
Boston and Wasserstein Perella regarding the scope of due diligence required
and the timetable for making written proposals to the Company with respect to
the structure and financial terms of a proposed transaction.
 
  On February 9, 1998, Mr. Hummer met with Mr. Jackson at Purchaser's offices
in Dallas to discuss the business of Purchaser and the possibility of Mr.
Hummer and certain other of the Company's executive officers continuing with
the combined operations. The terms of the Termination Compensation Agreements
between the Company and Messrs. Hummer, Cooney and Roberts and Mr. Max C.
Aiken, Executive Vice President Refractory Operations of the Company, were
discussed in the context of the proposed structure of an acquisition
transaction by Purchaser. Mr. Jackson also inquired as to the interest of
certain executive officers in converting a portion of their Company Options to
Purchaser Options.
 
  On February 18, 1998, Mr. Hummer met again with Mr. Jackson in Dallas. At
this meeting, Mr. Jackson expressed Purchaser's strong interest in acquiring
the Company. Mr. Hummer also disclosed to Mr. Jackson a grant of the severance
enhancement agreements to five additional officers and one other employee of
the Company by which each such person would receive a severance payment equal
to six months' salary, in addition to the Company's normal severance benefits,
if the officer or employee were terminated by an acquiring company within one
year after the date of consummation of the acquisition.
 
  On February 23, 1998, a telephonic meeting of the Board of Directors was
held to consider extending a non-binding proposal to the Company to acquire
all of its outstanding Common Stock for cash. After discussions with
Purchaser's counsel and consideration of a valuation analysis by Wasserstein
Perella, the Board of Directors of Purchaser authorized its management to make
a non-binding written proposal to the Company to acquire all of the Company's
outstanding Common Stock (on a fully diluted basis) for $22.00 per Share in
cash. The proposal was conveyed later in the day to the Company through Credit
Suisse First Boston and was conditioned upon the completion of several items
of due diligence, the negotiation of a definitive agreement with respect to a
tender offer and merger and the approval of the transaction by the Boards of
Directors of both companies.
 
  On February 24, 1998, a telephonic meeting of the Board of Directors of the
Company was held to discuss, among other items, the written proposal that had
been submitted by Purchaser to the Company. With the advice
 
                                      15
<PAGE>
 
and assistance of Credit Suisse First Boston and the Company's outside legal
counsel, there was a consensus of the Company's Board that the Purchaser's
proposal should be pursued. If negotiations resulted in a definitive
agreement, the Company's Board of Directors instructed management to report
back to it with management's recommendation.
 
  On February 25, 1998, Purchaser requested an exclusivity agreement by which
the Company would agree to pursue negotiations with respect to a definitive
acquisition agreement solely with Purchaser during an agreed-upon period of
time. The Company indicated its agreement to enter into such an agreement and
the parties negotiated and executed an exclusivity letter which extended
through midnight on March 4, 1998.
 
  On February 26 and 27, 1998, representatives of management of Purchaser and
the Company met in St. Louis, Missouri with their respective legal and
financial advisors to negotiate a definitive Merger Agreement.
 
  The form of the Merger Agreement, pursuant to which Purchaser agreed to
initiate the Offer for all of the Shares for a price of $22.00, net to the
seller in cash, and to consummate the Merger for the balance of the Shares not
purchased in the Offer at $22.00 in cash, was presented to their respective
Boards of Directors for approval in the afternoon and evening of March 2,
1998.
 
  On March 2, 1998, the Board of Directors of Purchaser met, at which meeting
Mr. Jackson and other officers of Purchaser updated the Board of Directors of
Purchaser concerning the discussions with the Company. Purchaser's counsel
advised the Purchaser's Board concerning the proposed Merger Agreement, and
Purchaser's financial advisors, Wasserstein Perella, advised the Board of
Directors of Purchaser concerning the financial terms of the proposed
transaction. Wasserstein Perella orally delivered its opinion to the Board of
Directors of Purchaser that as of March 2, 1998, the $22.00 per Share cash
consideration to be paid by Purchaser pursuant to the Merger and Offer is fair
to Purchaser from a financial point of view. Wasserstein Perella subsequently
delivered to Purchaser its written opinion, subject to the assumptions,
limitations and other matters described therein, confirming its oral opinion
delivered at the March 2, 1998, meeting of the Board of Directors of
Purchaser. The Board of Directors of Purchaser unanimously approved the Offer
and the Merger Agreement.
 
  On March 2, 1998, the Board of Directors of the Company met, at which
meeting Mr. Hummer and other officers of the Company updated the Board of
Directors of the Company concerning the discussions with Purchaser. The
Company's counsel advised the Company's Board concerning the proposed Merger
Agreement, and the Company's financial advisors, Credit Suisse First Boston,
advised the Board of Directors of the Company concerning the financial terms
of the proposed transaction. Credit Suisse First Boston delivered its opinion
to the Board of Directors of the Company that as of March 2, 1998, the $22.00
per Share cash consideration to be received by stockholders of the Company
pursuant to the Merger and Offer is fair to such stockholders from a financial
point of view. The Board of Directors of the Company unanimously determined
that the Offer and the Merger is fair to and in the best interests of the
Company and its stockholders and unanimously approved the Offer and the Merger
Agreement and unanimously recommended that the Company's stockholders accept
the Offer and tender their Shares pursuant to the Offer.
 
  The final terms of the definitive Merger Agreement were agreed to and the
Merger Agreement was executed on March 3, 1998 and a public announcement of
the execution of the Merger Agreement was made prior to the opening of trading
on the NYSE on March 4, 1998.
 
11. PURPOSE OF THE OFFER; PLANS FOR THE COMPANY; THE MERGER.
 
  Purpose. The purpose of the Offer is to acquire for cash as many outstanding
Shares as possible as a first step in acquiring the entire equity interest in
the Company.
 
  If the Merger Sub acquires a majority of the outstanding Shares pursuant to
the Offer, it will have the vote necessary under the DGCL to approve the
Merger. Under the DGCL, if the Merger Sub owns at least 90% of the outstanding
Shares, the Merger may be effected without the vote of the Company's
stockholders. Therefore, if 7,261,799 Shares (or such greater number as may be
necessary if options are exercised) are acquired pursuant to the Offer or
otherwise, the Merger Sub will be able to and intends to effect the Merger
without a meeting of holders of Shares. The Merger Agreement provides that,
promptly after expiration of the Offer and receipt of any required approval by
the Company's stockholders of the Merger Agreement and the satisfaction or
waiver of certain other conditions, the Merger Sub will be merged into the
Company. Upon consummation of the
 
                                      16
<PAGE>
 
Merger, each then outstanding Share (other than Shares owned by the Purchaser
Companies or Shares that are held by Dissenting Stockholders) shall, by virtue
of the Merger and without any action on the part of the holder thereof, be
converted into the right to receive the Merger Consideration.
 
  The respective obligations of the Company, Purchaser and the Merger Sub to
consummate the Merger are subject to the fulfillment of certain conditions set
forth in the Merger Agreement, any or all of which may be waived in whole or
in part by Purchaser or the Merger Sub, as the case may be, to the extent
permitted by applicable law, including (i) if required by the DGCL, the
approval by the holders of a majority of the Shares of the Merger Agreement,
in accordance with applicable law and the certificate of incorporation and by-
laws of the Company, (ii) the purchase by the Merger Sub (or one of the
Purchaser Companies) of Shares pursuant to the Offer, and (iii) there being no
statute, rule, regulation, judgment, decree, injunction or other order
(whether temporary, preliminary or permanent) enacted, issued, promulgated,
enforced or entered by any United States or state court or other Governmental
Entity of competent jurisdiction or regulatory authority in effect which
prohibits consummation of the transactions contemplated by the Merger
Agreement (collectively, an "Order").
 
  Termination Provisions. According to its terms, the Merger Agreement may be
terminated and the transactions contemplated thereby abandoned at any time
prior to the Effective Time, before or after approval by holders of Shares, by
the mutual consent of Purchaser and the Company, by action of their respective
Boards of Directors. In addition, the Merger Agreement may be terminated and
the transactions contemplated thereby abandoned at any time prior to the
Effective Time, before or after approval by holders of Shares, by action of
the Board of Directors of either Purchaser or the Company if (i) the Merger
Sub, or any Purchaser Company, shall have terminated the Offer without
purchasing any Shares pursuant thereto; or (ii) the Merger shall not have been
consummated by August 31, 1998, whether or not such date is before or after
the approval by holders of Shares; or (iii) if required, the approval of
stockholders of the Company shall not have been obtained at a meeting duly
convened therefor; or (iv) any court of competent jurisdiction or other
Governmental Entity located or having jurisdiction within the United States or
any country in which either the Company or Purchaser, directly or indirectly,
has material assets or operations, shall have issued a final order, decree or
ruling or taken any other final action restraining, enjoining or otherwise
prohibiting the Offer or the Merger and such order, decree, ruling or other
action is or shall have become final and nonappealable. The Merger Agreement
may also be terminated and the transactions contemplated thereby may be
abandoned at any time prior to the Effective Time, before or after the
approval by holders of Shares, by action of the Board of Directors of
Purchaser if (i) the Company shall have breached or failed to perform in any
material respect any of the covenants or agreements contained in the Merger
Agreement to be complied with or performed by the Company prior to such date
of termination which breach or failure shall not have been cured prior to the
earlier of (A) five business days following the giving of written notice to
the Company of such breach or failure and (B) two business days prior to the
date on which the Offer is then scheduled to expire, or any representation or
warranty of the Company set forth in the Merger Agreement shall have been
inaccurate or incomplete when made except for such failures to be complete or
accurate that, individually or in the aggregate, could not reasonably be
expected to have a material adverse effect on the financial condition,
properties, business or results of operations of the Company and its
subsidiaries taken as a whole or could prevent or materially delay the
transactions contemplated by the Merger Agreement or impair the ability of
Purchaser, the Merger Sub, the Company or any of their respective affiliates,
following consummation of the Offer or the Merger, to conduct any material
business or operations in any jurisdiction where they are now being conducted,
(ii) the Board of Directors of the Company (or a special committee thereof)
shall have amended, modified or withdrawn in a manner adverse to Purchaser or
the Merger Sub its approval or recommendation of the Offer, the Merger
Agreement or the Merger or the Board of Directors of the Company, upon request
by Purchaser, shall fail to reaffirm such approval or recommendation, or shall
have endorsed, approved or recommended any other Acquisition Proposal (as
defined in the Merger Agreement), or shall have resolved to do any of the
foregoing, or (iii) the Company or any of the other persons or entities
described in Section 7.2 of the Merger Agreement shall take any actions that
would be proscribed by Section 7.2 of the Merger Agreement but for the
exception therein allowing certain actions to be taken if required by
fiduciary obligations under applicable law as advised in writing by counsel.
The Merger Agreement may be terminated and the transactions contemplated
thereby may be abandoned at any time prior to the Effective Time, before or
after the approval by holders of Shares, by action of the Board of Directors
of the Company, (i) if Purchaser or
 
                                      17
<PAGE>
 
the Merger Sub (or another Purchaser Company) (x) shall have breached or
failed to perform in any material respect with any of the covenants or
agreements contained in the Merger Agreement to be complied with or performed
by Purchaser or the Merger Sub prior to such date of termination which shall
not have been cured prior to the earlier of (A) five business days following
the giving of written notice to Purchaser of such breach or failure and (B)
two business days prior to the date on which the Offer is then scheduled to
expire, or (y) shall have failed to commence the Offer within the time
required in Section 1.1 of the Merger Agreement, or (ii) if (w) the Company is
not in material breach of any of the terms of the Merger Agreement, (x) the
Board of Directors of the Company authorizes the Company, subject to complying
with the terms of the Merger Agreement, to enter into a binding written
agreement concerning a transaction that constitutes a Superior Proposal (as
defined in the Merger Agreement) and the Company notifies Purchaser in writing
that it intends to enter into such an agreement, attaching the most current
version of such agreement (which shall include all of the material terms,
including the price proposed to be paid for Shares pursuant thereto) to such
notice, (y) Purchaser does not make, within two business days of receipt of
the Company's written notification of its intention to enter into a binding
agreement for a Superior Proposal, an offer that the Board of Directors of the
Company determines, in good faith after consultation with its financial
advisors, is at least as favorable, from a financial point of view, to the
stockholders of the Company as the Superior Proposal and (z) the Company,
prior to such termination, pays to Purchaser in immediately available funds
the fees required to be paid pursuant to Section 9.5(b) of the Merger
Agreement.
 
  In the event of the termination of the Merger Agreement, no party to the
Merger Agreement (or any of its directors or officers) shall have any
liability or further obligation to any other party to the Merger Agreement,
except as provided in Sections 9.5(b) and 10.2 therein and except that nothing
therein will relieve any party from liability for any willful breach of the
Merger Agreement; provided, however, that if the Merger Agreement is
terminated by Purchaser pursuant to Section 9.3(i) or the Company pursuant to
Section 9.4(i) therein, the terminating party's rights to pursue all legal
remedies will survive such termination unimpaired.
 
  If (i) (x) the Offer shall have remained open for a minimum of at least 20
business days, (y) after the date of the Merger Agreement any corporation,
partnership, person, other entity or group (as defined in Section 13(d)(3) of
the Exchange Act) other than Purchaser or the Merger Sub or any of their
respective subsidiaries or affiliates (collectively, a "Person") shall have
become the beneficial owner of 20% or more of the outstanding Shares or shall
have publicly announced a proposal or intention to make an Acquisition
Proposal or any Person shall have commenced, or shall have publicly announced
an intention to commence, a tender offer or exchange offer for 20% or more of
the outstanding Shares, and (z) the Minimum Condition shall not have been
satisfied and the Offer is terminated without the purchase of any Shares
thereunder, or (ii) Purchaser shall have terminated the Merger Agreement
pursuant to Section 9.3(ii) or Section 9.3(iii) thereof or (iii) the Company
shall have terminated the Merger Agreement pursuant to Section 9.4(ii)
thereof; then the Company shall promptly, but in no event later than two days
after the date of such termination, pay Purchaser a fee of $8,000,000 and
shall reimburse Purchaser and the Merger Sub (not later than one business day
after request by Purchaser or the Merger Sub) for all of the out-of-pocket
charges and expenses, including financing fees, incurred by Purchaser or the
Merger Sub in connection with the Merger Agreement and the transactions
contemplated by the Merger Agreement up to a maximum amount of $1,500,000, in
each case payable by wire transfer in same day funds. The Company thereby
acknowledged that the agreements described above are an integral part of the
transactions contemplated in the Merger Agreement, and that, without these
agreements, Purchaser and the Merger Sub would not have entered into the
Merger Agreement; accordingly, if the Company fails to promptly pay the amount
due pursuant to Section 9.5(b) of the Merger Agreement, and, in order to
obtain such payment, Purchaser or the Merger Sub commences a suit which
results in a judgment against the Company for the fee set forth in such
Section, the Company shall pay to Purchaser or the Merger Sub its costs and
expenses (including attorneys' fees) in connection with such suit, together
with interest on the amount of the fee at the prime rate of Bank of America
National Trust and Savings Association on the date such payment was required
to be made. The payments made by the Company pursuant to Section 9.5(b) of the
Merger Agreement are the sole and exclusive remedy of Purchaser and the Merger
Sub for any claim that Purchaser or the Merger Sub may have arising from or
relating to the events set forth in Section 9.5(b)(i), (ii) or (iii) of the
Merger Agreement.
 
                                      18

  Amendment. Subject to the applicable provisions of the DGCL, at any time
prior to the Effective Time, the Merger Agreement may be modified or amended
by written agreement executed and delivered by duly authorized officers of the
respective parties.
 
  Treatment of Options. The Merger Agreement provides that, immediately prior
to the Effective Time, the Company shall take such actions as may be necessary
such that immediately prior to the Effective Time each stock option
outstanding and unexercised (the "Option") pursuant to the Company's stock
option and incentive plans (the "Stock Plans"), whether or not then
exercisable, shall be canceled and shall cease to be exercisable. In
consideration for such cancellation, the holder thereof, upon surrender of
such Option, will receive an amount in cash from the Company equal to the
result of multiplying the number of shares of Common Stock previously subject
to such Option by the difference between the Merger Consideration and the per
share exercise price of such Option.
 
  The Merger Agreement provides that Paul F. Hummer II may, by written notice
to Purchaser received by Purchaser not less than ten (10) business days prior
to the Effective Time, elect to convert the 75,000 Options held by him, into
options ("Purchaser Options") to purchase Purchaser common stock ("Purchaser
Common Stock"). Any such election shall identify the Options to be converted
into Purchaser Options and shall become irrevocable upon receipt by Purchaser
of the notice of election. If such election is made, at the Effective Time,
each Option to be converted shall be deemed to constitute an option to acquire
Purchaser Common Stock on the same terms of the applicable Stock Plan and the
stock option agreement by which it is evidenced. From and after the Effective
Time, (A) each such Option may be exercised solely for shares of Purchaser
Common Stock, (B) the number of shares of Purchaser Common Stock subject to
such Option shall be equal to the result (rounded down to the nearest whole
share) of multiplying the number of shares of Common Stock subject to such
Option immediately prior to the Effective Time by a fraction (the "Conversion
Fraction"), where (x) the numerator is equal to the Merger Consideration and
(y) the denominator is equal to the average of the last reported sales prices
of the Purchaser Common Stock on the five business days immediately prior to
the date of the Merger Agreement and (C) the per share exercise price under
each such Option shall be equal to the result (rounded up to the nearest cent)
of dividing the per share exercise price under each such Option by the
Conversion Fraction; provided, however, that with respect to any Option which
is an "incentive stock option", within the meaning of Section 422 of the
Internal Revenue Code, the adjustments provided by the Merger Agreement shall
be effected in a manner consistent with the requirements of Section 424(a) of
the Internal Revenue Code. No payment shall be made pursuant to the Merger
Agreement with respect to any portion of an Option that is converted into a
Purchaser Option.
 
  Pursuant to the Merger Agreement, at or prior to the Effective Time,
Purchaser shall take all corporate action necessary to reserve for issuance a
sufficient number of shares of Purchaser Common Stock for delivery upon
exercise of Options assumed by it in accordance with the Merger Agreement as
soon as administratively feasible following the Effective Time, file a
registration statement on Form S-8 (or any successor or other appropriate
form) with respect to the Purchaser Common Stock subject to such Options (or
shall cause such Option to be deemed an option issued pursuant to a Purchaser
stock option plan for which Purchaser Common Stock have previously been
registered pursuant to an appropriate registration form). Purchaser shall use
its best efforts to maintain the effectiveness of such registration statement
(and maintain the current status of the prospectus or prospectuses contained
therein) for so long as the Options remain outstanding.
 
  Indemnification of Officers and Directors. The Merger Agreement provides
that, from and after the Effective Time, Purchaser agrees that it will cause
the Surviving Corporation to indemnify and hold harmless each present and
former director and officer of the Company, determined as of the Effective
Time (the "Indemnified Parties"), against any costs or expenses (including
reasonable attorneys' fees), judgments, fines, losses, claims, damages or
liabilities (collectively, "Costs") incurred in connection with any claim,
action, suit, proceeding or investigation, whether civil, criminal,
administrative or investigative, arising out of matters existing or occurring
at or prior to the Effective Time, whether asserted or claimed prior to, at or
after the Effective Time, to the fullest extent that the Company is permitted
to do so under Delaware law and the Company
 
                                      19
<PAGE>
 
Certificate or Company By-Laws in effect on the date of the Merger Agreement
(and Purchaser shall also advance expenses as incurred to the fullest extent
permitted under applicable law provided the person to whom expenses are
advanced provides an undertaking to repay such advances if it is ultimately
determined that such person is not entitled to indemnification); provided that
any determination required to be made with respect to whether an officer's or
director's conduct complies with the standards set forth under Delaware law
and the Company Certificate and Company By-Laws shall be made by independent
counsel selected by the Surviving Corporation.
 
  Pursuant to the Merger Agreement, any Indemnified Party wishing to claim
indemnification, upon learning of any such claim, action, suit, proceeding or
investigation, shall promptly notify Purchaser thereof. In the event of any
such claim, action, suit, proceeding or investigation (whether arising before
or after the Effective Time), (i) Purchaser or the Surviving Corporation shall
have the right to assume the defense thereof and Purchaser shall not be liable
to such Indemnified Parties for any legal expenses of other counsel or any
other expenses subsequently incurred by such Indemnified Parties in connection
with the defense thereof, except that if Purchaser or the Surviving
Corporation elects not to assume such defense or counsel for the Indemnified
Parties advises that, in such counsel's reasonable judgment, there are
material issues that constitute conflicts of interest between Purchaser or the
Surviving Corporation and the Indemnified Parties, the Indemnified Parties may
retain counsel satisfactory to them, and Purchaser or the Surviving
Corporation shall pay all reasonable fees and expenses of such counsel for the
Indemnified Parties promptly as statements therefor are received; provided,
however, that Purchaser shall be obligated to pay for only one firm of counsel
for all Indemnified Parties in any jurisdiction, (ii) the Indemnified Parties
will cooperate in the defense of any such matter and (iii) Purchaser shall not
be liable for any settlement effected without its prior written consent; and
provided, further, however, that Purchaser shall not have any obligation
hereunder to any Indemnified Party when and if a court of competent
jurisdiction shall ultimately determine, and such determination shall have
become final, that the indemnification of such Indemnified Party in the manner
contemplated by the Merger Agreement is prohibited by applicable law.
 
  Pursuant to the Merger Agreement, the Surviving Corporation shall be
permitted to maintain the Company's existing officers' and directors'
liability insurance ("D&O Insurance") for a period of two years after the
Effective Time so long as the annual premium therefor is not in excess of 150%
of the last annual premium paid prior to the date of the Merger Agreement (the
"D&O Premium"); provided, however, if the existing D&O Insurance expires, is
terminated or canceled during such two-year period, the Surviving Corporation
will use its best efforts to obtain as much D&O Insurance as can be obtained
for the remainder of such period for a premium not in excess (on an annualized
basis) of the D&O Premium.
 
  Treatment of Employee Benefits. Pursuant to the Merger Agreement, Purchaser
agrees that during the period commencing at the Effective Time and ending on
the first anniversary thereof, the employees of the Company will continue to
be provided with benefits under employee benefit plans (other than stock
options or other plans involving the issuance of securities of the Company or
Purchaser) which in the aggregate are substantially comparable to those
currently provided by the Company to such employees; provided, however, that
employees covered by collective bargaining agreements need not be provided
with such benefits. Purchaser will cause each employee benefit plan of
Purchaser in which employees of the Company are eligible to participate to
take into account for purposes of eligibility and vesting thereunder the
service of such employees with the Company as if such service were with
Purchaser. Purchaser will, and will cause the Surviving Corporation to, honor
without modification all employee benefit obligations to current and former
employees of the Company accrued as of the Effective Time and, to the extent
set forth in the Disclosure Letter, all employee severance plans in existence
on the date of the Merger Agreement and all employment or severance agreements
entered into prior to the date of the Merger Agreement.
 
  ESOP Distributions and Termination. As soon as practicable following the
Effective Time, Purchaser and the Company shall take all actions necessary or
appropriate to cause the A.P. Green Industries, Inc. Employee Stock Ownership
Trust, which implements and forms part of the A.P. Green Investment Plan
(collectively, the "ESOP"), to provide for the use of all proceeds received
pursuant to the Offer from the tender of Shares allocated to the suspense
account of the ESOP, as follows: first, such proceeds shall be applied to
repay any
 
                                      20
<PAGE>
 
outstanding loan incurred by the ESOP; and secondly, the balance of such
proceeds shall be allocated to participants' Employer Match ESOP account in
proportion to the total aggregate value of such accounts of the participants
as of the accounting date immediately preceding the Effective Time, except to
the extent such allocations could exceed the limits on annual contributions
pursuant to Section 415 of the Code. In addition, as soon as is reasonably
practicable following the Effective Time (or, if deemed appropriate by
Purchaser and the Company, after receipt of a favorable determination letter
from the Internal Revenue Service on the effect of termination of the ESOP)
Purchaser and the Company shall terminate the ESOP and distribute all proceeds
to the participants in accordance therewith. Notwithstanding the foregoing,
Purchaser shall have no obligation to implement this Section 7.8(d) if such
implementation would violate the terms of the ESOP or jeopardize the tax-
qualified status of the ESOP.
 
  Composition of the Board of Directors. Pursuant to the Merger Agreement, if
requested by Purchaser, the Company will, subject to compliance with
applicable law and promptly following the purchase by the Merger Sub of Shares
pursuant to the Offer, take all actions necessary to cause persons designated
by Purchaser to become directors of the Company so that the total number of
such persons equals not less than the product of (i) the total number of
directors on the Board of Directors of the Company (giving effect to the
directors elected pursuant to the Merger Agreement) and (ii) a fraction the
numerator of which is the aggregate number of Shares beneficially owned by the
Merger Sub or any affiliate of the Merger Sub and the denominator of which is
the total number of Shares then outstanding. In furtherance thereof, the
Company will increase the size of the Board of Directors of the Company, or
use its reasonable efforts to secure the resignation of directors, or both, as
is necessary to permit Purchaser's designees to be elected to the Board of
Directors of the Company. At such time, the Company, if so requested, will use
its reasonable efforts to cause persons designated by Purchaser to constitute
the same proportionate representation of each committee of the Board of
Directors of the Company, each board of directors of each subsidiary of the
Company and each committee of each such board (in each case to the extent of
the Company's ability to elect such persons). No directors appointed by
Purchaser shall be entitled to receive any compensation or benefits currently
in effect for the Company's non-employee directors. The Company's obligations
to appoint designees to the Board of Directors of the Company shall be subject
to Section 14(f) of the Exchange Act and Rule 14f-1 promulgated thereunder.
The Company shall promptly take all actions required pursuant to such Section
and Rule in order to fulfill its obligations under the Merger Agreement and
shall include in the Schedule 14D-9, or in a separate Rule 14f-1 information
statement provided to stockholders, such information with respect to the
Company and its officers and directors as is required under Section 14(f) and
Rule 14f-1 to fulfill its obligations under the Merger Agreement. Purchaser
and the Merger Sub will supply to the Company and will be solely responsible
for any information with respect to either of them and their nominees,
officers, directors and affiliates required by Section 14(f) and Rule 14f-1.
 
  Acquisition Proposals. Pursuant to the Merger Agreement, the Company has
agreed that neither it nor its affiliates and its and their respective
officers, directors, employees, representatives and agents (including, without
limitation, any investment banker, attorney or accountant retained by the
Company or any of its subsidiaries) shall immediately cease all existing
discussions or negotiations, if any, with any parties conducted before the
date of the Merger Agreement with respect to any acquisition or exchange of
all or any material portion of the assets of, or more than 15% of the equity
interest in, the Company or any of its subsidiaries (by direct purchase from
the Company, tender or exchange offer or otherwise) or any business
combination, merger, consolidation or similar transaction (including an
exchange of stock or assets) with or involving the Company or any subsidiary
or division of the Company (an "Acquisition Transaction"). Neither the Company
nor any of its affiliates, nor any of its or their respective officers,
directors, employees, representatives or agents (including, without
limitation, any investment banker, attorney or accountant retained by the
Company or any of its subsidiaries) shall, directly or indirectly, encourage,
solicit, participate in or initiate discussions or negotiations with, or
provide any information to, any corporation, partnership, person or other
entity or group (other than Purchaser and the Merger Sub, any affiliate or
associate of Purchaser and the Merger Sub or any designees of Purchaser and
the Merger Sub) with respect to any inquiries or the making of any offer or
proposal (including, without limitation, any offer or proposal to the
stockholders of the Company) concerning an Acquisition Transaction (an
"Acquisition Proposal"), unless (i) the Board of Directors of the Company
determines in good faith after consultation with outside legal counsel that
such action is necessary in order for its directors to comply with
 
                                      21
<PAGE>
 
their respective fiduciary duties under applicable law and (ii) the Board of
Directors of the Company determines in good faith (after consultation with its
financial advisor) that such Acquisition Proposal, if accepted, is reasonably
likely to be consummated (taking into account all legal, financial and
regulatory aspects of the proposal, the person making the proposal and all
other relevant factors) and would, if consummated, result in a transaction
more favorable to the Company's stockholders from a financial point of view
than the transaction contemplated by the Merger Agreement (any such more
favorable Acquisition Proposal being referred to in the Merger Agreement as a
"Superior Proposal"). The Company will take the necessary steps to inform the
individuals or entities referred to in the first sentence of this paragraph of
the obligations undertaken pursuant to the Merger Agreement. The Company will
notify Purchaser immediately if any such inquiries or proposals are received
by, any such information is requested from, or any such negotiations or
discussions are sought to be initiated or continued with the Company, the name
of the person making such proposals, the material terms and conditions of such
proposals and thereafter shall keep Purchaser informed, on a current basis, of
the status and terms of such proposals and the status of such negotiations or
discussions. The Company agreed not to release any third party from, or waive
any provisions of, any confidentiality or standstill agreement to which the
Company is a party, unless the Board of Directors of the Company shall have
determined in good faith, based upon the advice of outside counsel to the
Company, that failing to release such third party or waive such provisions
would constitute a breach of the fiduciary duties of the Board of Directors of
the Company under applicable law.
 
  Covenants. The Merger Agreement also contains certain other restrictions as
to the conduct of business by the Company pending the Merger, as well as
representations and warranties of each of the parties customary in
transactions of this kind.
 
  Appraisal Rights. No appraisal rights are available in connection with the
Offer. However, if the Merger is consummated, each stockholder of the Company
who has neither voted in favor of the Merger nor consented thereto in writing
will be entitled to an appraisal by the Delaware Court of Chancery of the fair
value of his Shares, exclusive of any element of value arising from the
accomplishment or expectation of the Merger, together with a fair rate of
interest, if any, to be paid. In determining such fair value, the Court may
consider all relevant factors. The value so determined could be more or less
than the consideration to be paid in the Offer and the Merger. Any judicial
determination of the fair value could be based upon considerations other than
or in addition to the market value of the Shares, including, among other
things, asset values and earning capacity.
 
  Rule 13e-3. Rule 13e-3 under the Exchange Act, which Purchaser does not
believe would be applicable to the Merger, would require, among other things,
that certain financial information concerning the Company and certain
information relating to the fairness of the proposed transaction and the
consideration offered to stockholders of the Company therein, be filed with
the SEC and disclosed to stockholders of the Company prior to consummation of
the transaction.
 
  Rights Agreement. Set forth below is a summary description of the Rights as
filed with the Company's Registration Statement on Form 8-A dated November 13,
1997, relating to the Rights. On November 13, 1997, the Board of Directors of
the Company declared a dividend of one Right for each outstanding share of
Common Stock. The dividend was payable on January 7, 1998 (the "Record Date")
to the stockholders of record on that date. Each Right entitles the registered
holder to purchase from the Company one one-hundredth of a share of a
Preferred Share of the Company at a price of $45.00 per one one-hundredth of a
Preferred Share (the "Purchase Price"), subject to adjustment. The description
and terms of the Rights are set forth in the Rights Agreement.
 
  Initially, the Rights will be evidenced by the stock certificates
representing shares of Common Stock then outstanding, and no separate Right
Certificates, as defined in the Rights Agreement, will be distributed. Until
the earlier to occur of (i) 10 days following a public announcement that a
person or group of affiliated or associated persons (an "Acquiring Person")
have acquired beneficial ownership of 20% or more of the outstanding shares of
Common Stock or (ii) 10 business days (or such later date as may be determined
by action of a majority of the Continuing Directors prior to such time as any
person or group of affiliated persons becomes an Acquiring Person) following
the commencement of, or announcement of an intention to make, without the
prior written
 
                                      22
<PAGE>
 
approval of a majority of the Continuing Directors, a tender offer or exchange
offer the consummation of which would result in the beneficial ownership by a
person or group of 20% or more of the voting power of the Company (the earlier
of such dates being called the "Distribution Date"), the Rights will be
evidenced, with respect to any of the shares of Common Stock certificates
outstanding as of the Record Date, by such share of Common Stock certificate
to which a copy of this Summary of Rights may be attached.
 
  The Rights Agreement provides that, until the Distribution Date (or earlier
redemption or expiration of the Rights), the Rights will be transferred with
and only with the Common Stock. Until the Distribution Date (or earlier
redemption or expiration of the Rights), new Common Stock certificates issued
after the Record Date upon transfer or new issuance of Common Stock will
contain a notation incorporating the Rights Agreement by reference. Until the
Distribution Date (or earlier redemption or expiration of the Rights) the
surrender for transfer of any certificates for Common Stock outstanding as of
the Record Date will also constitute the transfer of the Rights associated
with the Common Stock represented by such certificate. As soon as practicable
following the Distribution Date, separate certificates evidencing the Rights
("Right Certificates") will be mailed to holders of record of the Common Stock
as of the close of business on the Distribution Date and such separate Right
Certificates alone will evidence the Rights.
 
  The Rights are not exercisable until the Distribution Date. The Rights will
expire on January 6, 2008 (the "Final Expiration Date"), unless the Final
Expiration Date is extended or unless the Rights are earlier redeemed or
exchanged by the Company, in each case, as described below.
 
  The Purchase Price payable, and the number of Preferred Shares or other
securities or property issuable, upon exercise of the Rights are subject to
adjustment from time to time to prevent dilution (i) in the event of a stock
dividend on, or a subdivision, combination of reclassification of, the
Preferred Shares, (ii) upon the grant to holders of the Preferred Shares of
certain rights or warrants to subscribe for or purchase Preferred Shares at a
price, or securities convertible into Preferred Shares with a conversion
price, less than the then-current market price of the Preferred Shares or
(iii) upon the distribution to holders of the Preferred Shares of evidences of
indebtedness or assets (excluding regular periodic cash dividends paid out of
earnings or retained earnings or dividends payable in Preferred Shares) or of
subscription rights or warrants (other than those referred to above).
 
  The number of outstanding Rights and the number of one one-hundredths of a
Preferred Share issuable upon exercise of each Right are also subject to
adjustment in the event of a stock split of the Common Stock or a stock
dividend on the Common Stock payable in shares of Common Stock or
subdivisions, consolidations or combinations of the Common Stock occurring, in
any such case, prior to the Distribution Date.
 
  Preferred Shares purchasable upon exercise of the Rights will not be
redeemable. Each Preferred Share will be entitled to a minimum preferential
quarterly dividend payment of $1 per share but will be entitled to an
aggregate dividend of 100 times the dividend declared per share of Common
Stock. In the event of liquidation, the holders of the Preferred Shares will
be entitled to a minimum preferential liquidation payment of $100 per share
but will be entitled to an aggregate payment of 100 times the payment made per
share of Common Stock. Each Preferred Share will have 100 votes, voting
together with the shares of Common Stock. Finally, in the event of any merger,
consolidation or other transaction in which Common Shares are exchanged, each
Preferred Share will be entitled to receive 100 times the amount received per
share of Common Stock. These rights are protected by customary anti-dilution
provisions. Because of the nature of the Preferred Shares' dividend,
liquidation and voting rights, the value of the one one-hundredth interest in
a Preferred Share purchasable upon exercise of each Right should approximate
the value of one share of Common Stock. The Preferred Shares rank junior to
all other series of the Company's preferred stock.
 
  In the event that the Company is acquired in a merger or other business
combination transaction or 50% or more of its consolidated assets or earning
power are sold, proper provision will be made so that each holder of a Right
will thereafter have the right to receive, upon the exercise thereof at the
then current exercise price of the Right, that number of shares of common
stock of the acquiring company which at the time of such transaction will have
a market value of two times the exercise price of the Right. In the event that
any person or group of affiliated or associated persons becomes an Acquiring
Person, proper provision shall be made so that each holder
 
                                      23
<PAGE>
 
of a Right, other than Rights beneficially owned by the Acquiring Person
(which will thereafter be void), will thereafter have the right to receive
upon exercise that number of shares of Common Stock having a market value of
two times the exercise price of the Right (or, if such number of shares of
Common Stock is not authorized, the Company may issue cash, debt, stock or a
combination thereof in exchange for the Rights).
 
  At any time after any Person becomes an Acquiring Person and prior to the
acquisition by such person or group of 50% or more of the outstanding Common
Stock, the Board of Directors of the Company may exchange the Rights (other
than Rights owned by such person or group which will have become void) in
whole or in part, at an exchange ratio of one shares of Common Stock, or one
one-hundredth of a Preferred Share (or of a share of a class or series of the
Company's preferred stock having equivalent rights, preferences and privileges
or the Company may issue cash, debt or other property or any combination
thereof), per Right (subject to adjustment).
 
  With certain exceptions, no adjustment in the Purchase Price will be
required until cumulative adjustments require an adjustment of at least 1% in
such Purchase Price. No fractional Preferred Shares will be issued (other than
fractions which are integral multiples of one one-hundredth of a Preferred
Share, which may, at the election of the Company, be evidenced by depositary
receipts) and in lieu thereof, an adjustment in cash will be made based on the
market price of the Preferred Shares on the last trading day prior to the date
of exercise.
 
  At any time prior to the earliest of (i) the time that a person has become
an Acquiring Person or (ii) the final Expiration Date, the Board of Directors
of the Company may redeem the Rights in whole, but not in part, at a price of
$.001 per Right (the "Redemption Price"). The redemption of the Rights may be
made effective at such time on such basis with such conditions as the Board of
Directors in its sole discretion may establish. Immediately upon any
redemption of the Rights, the right to exercise the Rights will terminate and
the only right of the holders of Rights will be to receive the Redemption
Price.
 
  The terms of the Rights may be amended by the Board of Directors of the
Company without the consent of the holders of the Rights, including an
amendment to lower certain thresholds described above to any percentage which
is (i) greater than the largest percentage of the outstanding shares of Common
Stock then known to the Company to be beneficially owned by any person or
group of affiliated or associated persons (other than the Company, any
Subsidiary of the Company, employee benefit plans of the Company or any
Subsidiary, or any entity holding shares of Common Stock pursuant to the terms
of any such plan) and (ii) not less than 10%, except that from and after such
time as any person or group of affiliated or associated persons becomes an
Acquiring Person no such amendment may adversely affect the interests of the
holders of the Rights.
 
  Until a Right is exercised, the holder thereof, as such, will have no rights
as a stockholder of the Company, including, without limitation, the right to
vote or to receive dividends.
 
  Pursuant to the Merger Agreement, the Board of Directors of the Company, at
its meeting on March 2, 1998, took all necessary action under the Rights
Agreement to provide that the execution of the Merger Agreement and the
consummation of the transactions contemplated thereby will not cause (i) the
Merger Sub and/or Purchaser to become an Acquiring Person or (ii) a
Distribution Date or a Stock Acquisition Date (as defined in the Rights
Agreement) to occur, irrespective of the number of Shares acquired pursuant to
the Offer. In addition, pursuant to the Merger Agreement, the Board of
Directors of the Company approved the amendment of the Rights Agreement on
March 2, 1998 so that (i) the consummation of the transactions contemplated
thereby will not cause (x) the Merger Sub and/or Purchaser to become an
Acquiring Person or (y) a Distribution Date or a Stock Acquisition Date (as
defined in the Rights Agreement) to occur, irrespective of the number of
Shares acquired pursuant to the Offer and (ii) all outstanding Rights will
expire upon the acceptance of Shares for payment pursuant to the Offer,
whether or not tendered and purchased pursuant to the Offer, and neither the
Company, the Merger Sub nor Purchaser shall have any obligations under the
Rights Agreement to any holder (or former holder) of Rights following
consummation of the Offer.
 
12. SOURCE AND AMOUNT OF FUNDS.
 
  The Merger Sub estimates that the total amount of funds required to purchase
all of the outstanding Shares pursuant to the Offer and the Merger and to pay
related fees and expenses will be approximately $192,000,000.
 
                                      24
<PAGE>
 
The Merger Sub expects to obtain these funds from capital contributions or
advances made by Purchaser. Purchaser currently plans to obtain the funds for
such capital contributions or advances from the sale of its Industrial Tool
business to Cooper Industries for $217.5 million. Purchaser has been notified
that the waiting period under the HSR Act applicable to the Industrial Tool
transaction expired on March 5, 1998. Accordingly, Purchaser believes that the
sale of its Industrial Tool business will be consummated prior to the
Expiration Date and that it will have the necessary funds to make the above-
referenced capital contributions or advances.
 
  If the consummation of the Industrial Tool transaction is delayed beyond the
Expiration Date, Purchaser plans to obtain the funds for such capital
contributions or advances from a combination of its working capital and
borrowings under the Credit Agreement, dated as of September 23, 1994, as
amended by the Seventh Amendment to Credit Agreement, dated as of February 19,
1998, among Purchaser and Bank of America National Trust and Savings
Association (the "Credit Facility") which provides a commitment of
$200,000,000, which can only be drawn in connection with the undertaking
described herein, and to the extent utilized, will be a term loan due August
31, 1998. The Credit Facility is provided by Bank of America National Trust
and Savings Association as agent (the "Agent") and lender (the "Lender").
 
  Under the Credit Agreement, Purchaser may request that the Lender make a
loan which bears interest by reference to a rate that, according to the terms
of the Credit Facility, and at the discretion of Purchaser, varies according
to rates offered for eurodollar deposits, the federal funds rate, or the
reference rate announced from time to time by Bank of America. Further,
Purchaser has agreed to pay a facility fee to the Lender, the amount of which
is conditioned to amounts borrowed related to this undertaking.
 
  The covenants in the Credit Facility restrict or limit, among other things,
(i) the incurrence of certain debt by Purchaser's subsidiaries, (ii) liens on
the assets of Purchaser and its subsidiaries, (iii) certain mergers,
consolidations and sales of assets by Purchaser and its subsidiaries and (iv)
the use of proceeds of the loans made under the Credit Facility. In addition,
the Credit Facility requires that Purchaser and its restricted subsidiaries,
on a consolidated basis, satisfy an indebtedness/capitalization ratio, an
indebtedness/net cash flow ratio and an interest coverage ratio.
 
  The foregoing description is qualified in its entirety by reference to the
Credit Facility, which is incorporated herein by reference and a copy of which
has been filed with the SEC as an exhibit to Purchaser's Tender Offer
Statement on Schedule 14D-1. The Credit Facility may be examined and copies
may be obtained at the place and in the manner set forth in Section 8.
 
  It is anticipated that the indebtedness incurred by Purchaser in connection
with the Offer and the Merger will be paid from funds generated internally by
Purchaser and its subsidiaries (including, after the Merger, if consummated,
dividends paid by the Surviving Corporation and its subsidiaries), through
additional borrowings, through application of proceeds of dispositions or
through a combination of two or more such sources. No final decisions have
been made, however, concerning the method Purchaser will employ to repay such
indebtedness. Such decisions, when made, will be based on Purchaser's review
from time to time of the advisability of particular actions, as well as on
prevailing interest rates and financial and other economic conditions.
 
13. CERTAIN CONDITIONS OF THE OFFER.
 
  Notwithstanding any other provision of the Offer, the 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) under the Exchange Act
(relating to the Merger Sub's obligation to pay for or return tendered Shares
promptly after termination or withdrawal of the Offer), pay for, or may delay
the acceptance for payment of or payment for, any tendered Shares, or may, in
its sole discretion, terminate or amend the Offer as to any Shares not then
paid for if, (i) prior to the expiration of the Offer, (x) a number of Shares
which, together with any Shares owned by Purchaser or the Merger Sub,
constitutes more than 50% of the voting power (determined on a fully-diluted
basis) of all the securities of the Company entitled to vote generally in the
election of directors or in connection with a merger shall not have been
validly tendered and not withdrawn prior to the expiration of the Offer (the
"Minimum Condition") or (y) any waiting periods under the HSR Act applicable
to the purchase of Shares
 
                                      25

statutes or regulations that are applicable to the Offer or the Merger shall
not have expired or been terminated, or any required filings, consents,
approvals, and authorizations of any Governmental Entity applicable to the
Offer or the Merger shall not have been obtained on terms satisfactory to
Purchaser in its reasonable judgment, or (ii) on or after March 3, 1998 and at
or before the time of payment for any of such Shares (whether or not any
Shares have theretofore been accepted for payment), any of the following
events shall occur:
 
    (a) there shall have occurred (i) any general suspension of, or
  limitation on prices for, trading in securities on the NYSE, (ii) a

  respect of banks in the United States, (iii) a commencement or escalation
  of a war, armed hostilities or other international or national calamity
  directly or indirectly involving the United States, (iv) any limitation
  (whether or not mandatory) by any Governmental Entity on, or any other
  event that might affect, the extension of credit by banks or other lending
  institutions, (v) a material change in United States or any other currency
  exchange rates or a suspension of, or limitation on, the markets therefor,
  (vi) or in the case of any of the foregoing existing at the time of the
  commencement of the Offer, a material acceleration or worsening thereof,
  (vii) any extraordinary or material adverse change in the market price of
  the Shares or in the United States securities or financial markets
  generally, including, without limitation, a decline of at least 20% in
  either the Dow Jones Average of Industrial Stocks or the Standard & Poor's
  500 index from the date of the Merger Agreement, or (viii) any material
  adverse change in the relevant financial markets that could reasonably be
  expected to materially and adversely affect the debt facilities related to
  the financing of the Offer;
 
    (b) the Company shall have breached or failed to perform in any material
  respect any of its obligations, covenants or agreements contained in the
  Merger Agreement or any representation or warranty of the Company set forth
  in the Merger Agreement shall have been inaccurate or incomplete in any
  material respect when made or thereafter shall become inaccurate or
  incomplete in any material respect;
 
    (c) there shall be threatened, instituted or pending any action,
  litigation, proceeding, investigation or other application (an "Action")

  seeking to restrain or prohibit the consummation of the transactions
  contemplated by the Offer or the Merger or other subsequent business
  combination, seeking to obtain any material damages or otherwise directly
  or indirectly relating to the transactions contemplated by the Offer or the
  Merger or other subsequent business combination; (ii) seeking to prohibit,
  or impose any material limitations on, Purchaser's or the Merger Sub's
  ownership or operation of all or any portion of their or the Company's

  dispose of or hold separate all or any portion of Purchaser's or the Merger
  Sub's or the Company's business or assets (including the business or assets
  of their respective affiliates and subsidiaries) as a result of the
  transactions contemplated by the Offer or the Merger or other subsequent
  business combination; (iii) seeking to make the acceptance for payment,
  purchase of, or payment for, some or all of the Shares illegal or render
  the Merger Sub unable to, or result in a material delay in, or restrict,
  the ability of the Merger Sub to, accept for payment, purchase or pay for
  some or all of the Shares; (iv) seeking to impose material limitations on
  the ability of Purchaser or the Merger Sub effectively to acquire or hold
  or to exercise full rights of ownership of the Shares including, without
  limitation, the right to vote the Shares purchased by them on an equal
  basis with all other Shares on all matters properly presented to the
  stockholders; or (v) that, in any event, in the judgment of Purchaser is
  reasonably likely to have a material adverse effect on the financial

  consummation of the transactions contemplated by the Offer and the Merger;
 
    (d) any statute, rule, regulation, order or injunction shall be sought,
  proposed, enacted, promulgated, entered, enforced or deemed or become

                                      26
<PAGE>
 
  court or other Governmental Entity other than the application to the Offer,
  the Merger, the Merger Agreement or other subsequent business combination
  of waiting periods under the HSR Act, that, in the judgment of Purchaser,
  could be expected to, directly or indirectly, result in any of the effects
  of, or have any of the consequences sought to be obtained or achieved in,
  any Action referred to in clauses (i) through (v) of paragraph (c) above;
 
    (e) a tender or exchange offer for some portion or all of the Shares
  shall have been commenced or publicly proposed to be made by another person
  (including the Company or its subsidiaries), or it shall have been publicly
  disclosed or Purchaser shall have learned that (i) any person (including
  the Company or its subsidiaries), entity or "group" (as defined in Section
  13(d) of the Exchange Act and the rules promulgated thereunder) shall have
  become the beneficial owner (as defined in Section 13(d) of the Exchange
  Act and the rules promulgated thereunder) of more than 20% of any class or
  series of capital stock of the Company (including the Shares) other than
  for bona fide arbitrage purposes or (ii) any person, entity or group shall
  have entered into a definitive agreement or an agreement in principle or
  made a proposal with respect to a tender offer or exchange offer for some
  portion or all of the Shares or a merger, consolidation or other business
  combination with or involving the Company;
 
    (f) any change shall have occurred (or any development shall have
  occurred involving a prospective change) or Purchaser or the Merger Sub
  shall have become aware of any fact (including, but not limited to, any
  such change) that has had, or is reasonably likely to have, a material
  adverse effect on the Company and its subsidiaries taken as a whole;
 
    (g) the Board of Directors of the Company (or a special committee
  thereof) shall have amended, modified or withdrawn its approval or
  recommendation of the Offer, the Merger Agreement or the Merger, or shall
  have failed to publicly reconfirm such approval or recommendation upon
  request by Purchaser or the Merger Sub, or shall have endorsed, approved or
  recommended any other Acquisition Proposal, or shall have resolved to do
  any of the foregoing; or
 
    (h) the Merger Agreement shall have been terminated by the Company or
  Purchaser or the Merger Sub in accordance with its terms or Purchaser or
  the Merger Sub shall have reached an agreement or understanding in writing
  with the Company providing for termination or amendment of the Offer or
  delay in payment for the Shares;
 
which, in the sole judgment of Purchaser and the Merger Sub, in any such case,
and regardless of the circumstances (including any action or inaction by
Purchaser or the Merger Sub) giving rise to any such conditions, makes it
inadvisable to proceed with the Offer and/or with such acceptance for payment
of or payment for Shares.
 
  The foregoing conditions are for the sole benefit of Purchaser and the
Merger Sub and may be asserted by Purchaser or the Merger Sub regardless of
the circumstances (including any action or inaction by Purchaser or the Merger
Sub) giving rise to such condition or may be waived by Purchaser or the Merger
Sub, by express and specific action to that effect, in whole or in part at any
time and from time to time in its sole discretion. Any determination by
Purchaser and the Merger Sub concerning any event described in this section
will be final and binding upon all parties. The failure by the Merger Sub at
any time to exercise any of the foregoing rights will not be deemed a waiver
of any such right, the waiver of any such right with respect to particular
facts and other circumstances will not be deemed a waiver with respect to any
other facts and circumstances, and each such right will be deemed an ongoing
right that may be asserted at any time and from time to time.
 
  A public announcement will 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. DIVIDENDS AND DISTRIBUTIONS.
 
  If, on or after March 3, 1998, the Company should split, combine or
otherwise change the Shares or its capitalization or shall disclose that it
has taken any such action, then the Merger Sub, in its discretion, may make
such adjustments in the Merger Consideration and other terms of the Offer as
it deems appropriate to reflect such split, combination or other change.
 
                                      27
<PAGE>
 
  If, on or after March 3, 1998, the Company should declare or pay any cash or
stock dividend (other than the regular quarterly cash dividends not in excess
of $0.04 per share of Common Stock at the normal time at which such dividends
are declared and paid) or other distribution on or issue any rights with
respect to the shares of Common Stock, payable or distributable to
stockholders of record on a date occurring on or after March 3, 1998 and prior
to the transfer to the name of the Merger Sub or its nominees or transferees
on the Company's stock transfer records of the shares of Common Stock
purchased pursuant to the Offer, then, without prejudice to the Merger Sub's
rights under Section 13, (i) the price payable by the Merger Sub pursuant to
the Offer will be reduced by the amount of any such cash dividend or
distribution and (ii) the whole of any non-cash dividend or distribution
(including additional shares of Common Stock or rights as aforesaid) received
by a tendering stockholder shall be required to be promptly remitted and
transferred by the tendering stockholder to the Depositary for the account of
the Merger Sub, accompanied by appropriate documentation of transfer. Pending
such remittance or appropriate assurance thereof, the Merger Sub will be,
subject to applicable law, entitled to all rights and privileges as owner of
any such non-cash dividend, distribution or right and may withhold the entire
purchase price or deduct from the purchase price the amount or value thereof,
as determined by the Merger Sub in its sole discretion.
 
15. CERTAIN LEGAL MATTERS
 
  General. Except as otherwise disclosed herein, based upon an examination of
publicly available filings with respect to the Company, Purchaser and the
Merger Sub are not aware of any licenses or other regulatory permits which
appear to be material to the business of the Company and which might be
adversely affected by the acquisition of Shares by the Merger Sub pursuant to
the Offer or of any approval or other action by any governmental,
administrative or regulatory agency or authority which would be required for
the acquisition or ownership of Shares by the Merger Sub pursuant to the
Offer. Should any such approval or other action be required, it is currently
contemplated that such approval or action would be sought or taken. There can
be no assurance that any such approval or action, if needed, would be obtained
or, if obtained, that it will be obtained without substantial conditions or
that adverse consequences might not result to the Company's or Purchaser's
business or that certain parts of the Company's or Purchaser's business might
not have to be disposed of in the event that such approvals were not obtained
or such other actions were not taken, any of which could cause the Merger Sub
to elect to terminate the Offer without the purchase of the Shares thereunder.
The Merger Sub's obligation under the Offer to accept for payment and pay for
Shares is subject to certain conditions. See Section 13.
 
  Antitrust Compliance. Under the HSR Act, certain acquisition transactions
may not be consummated unless certain information has been furnished to the
Antitrust Division of the Department of Justice (the "Antitrust Division") and
the Federal Trade Commission (the "FTC") and certain waiting period
requirements have been satisfied. The acquisition of Shares by the Merger Sub
is subject to these requirements. See Section 2 of this Offer to Purchase as
to the effect of the HSR Act on the timing of the Merger Sub's obligation to
accept Shares for payment.
 
  Pursuant to the HSR Act, Purchaser filed a Notification and Report Form with
respect to the acquisition of Shares pursuant to the Offer and the Merger with
the Antitrust Division and the FTC on March 4, 1998. Under the provisions of
the HSR Act applicable to the purchase of Shares pursuant to the Offer, such
purchases may not be made until the expiration of a 15-calendar day waiting
period following the filing by Purchaser. Accordingly, the waiting period
under the HSR Act will expire at 11:59 p.m., New York City time, on March 19,
1998, unless early termination of the waiting period is granted or Purchaser
receives a request for additional information or documentary material prior
thereto. Pursuant to the HSR Act, Purchaser has requested early termination of
the waiting period applicable to the Offer. There can be no assurances given,
however, that the 15-day HSR Act waiting period will be terminated early. If
either the FTC or the Antitrust Division were to request additional
information or documentary material from Purchaser, the waiting period would
expire at 11:59 p.m., New York City time, on the tenth calendar day after the
date of substantial compliance by Purchaser with such request. Thereafter, the
waiting period could be extended only by agreement or by court order. If the
acquisition of Shares is delayed pursuant to a request by the FTC or the
Antitrust Division for additional information or documentary material pursuant
to the HSR Act, the purchase of and payment for Shares will be
 
                                      28
<PAGE>
 
deferred until ten calendar days after the request is substantially complied
with unless the waiting period is sooner terminated by the FTC or the
Antitrust Division. See Section 2. Only one extension of such waiting period
pursuant to a request for additional information is authorized by the HSR Act,
except by agreement or by court order. Any such extension of the waiting
period will not give rise to any withdrawal rights not otherwise provided for
by applicable law. See Section 4. Although the Company is required to file
certain information and documentary material with the Antitrust Division and
the FTC in connection with the Offer, neither the Company's failure to make
such filings nor a request from the Antitrust Division or the FTC for
additional information or documentary material made to the Company will extend
the waiting period.
 
  The Antitrust Division and the FTC frequently scrutinize the legality under
the antitrust laws of transactions such as the proposed acquisition of Shares
by the Merger Sub pursuant to the Offer. At any time before or after the
Merger Sub's purchase of Shares, the Antitrust Division or the FTC could take
such action under the antitrust laws as it deems necessary or desirable in the
public interest, including seeking to enjoin the acquisition of Shares
pursuant to the Offer or seeking divestiture of Shares acquired by the Merger
Sub or the divestiture of substantial assets of Purchaser, the Company or any
of their respective subsidiaries. Private parties may also bring legal action
under the antitrust laws under certain circumstances. There can be no
assurance that a challenge to the Offer on antitrust grounds will not be made
or, if a challenge is made, what the result will be. See Section 13 of this
Offer to Purchase for certain conditions to the Offer that could become
applicable in the event of such a challenge.
 
  Foreign Approvals. The Company owns property or conducts business in various
foreign countries and jurisdictions. In connection with the acquisition of the
Shares pursuant to the Offer, the laws of certain of those foreign countries
and jurisdictions may require the filing of information with, or the obtaining
of the approval of governmental authorities in such countries and
jurisdictions, including the Regulatory Approvals. 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. There can be no
assurance that Purchaser will be able to cause the Company or its subsidiaries
to satisfy or comply with such laws or that compliance or non-compliance will
not have a material adverse effect on the financial condition, properties,
business or results of operations of the Company and its subsidiaries taken as
a whole or impair Purchaser, the Merger Sub or the Company or any of their
respective affiliates, following consummation of the Offer or Merger, to
conduct any material business or operations in any jurisdiction where they are
now being conducted. See Section 13.
 
  State Takeover Laws. A number of states have adopted laws and regulations
applicable to offers to acquire securities of corporations which are
incorporated in such states and/or which have substantial assets,
stockholders, principal executive offices or principal places of business
therein. In Edgar v. MITE Corporation, the Supreme Court of the United States
held that the Illinois Business Takeover Statute, which made the takeover of
certain corporations more difficult, imposed a substantial burden on
interstate commerce and was therefore unconstitutional. In CTS Corporation v.
Dynamics Corporation of America, the Supreme Court held that as a matter of
corporate law, and in particular, those laws concerning corporate governance,
a state may constitutionally disqualify an acquiror of "Control Shares" (ones
representing ownership in excess of certain voting power thresholds (e.g. 20%,
33% or 50%) of a corporation incorporated in its state and meeting certain
other jurisdictional requirements from exercising voting power with respect to
those shares without the approval of a majority of the disinterested
stockholders.
 
  Purchaser does not believe that any state takeover laws apply to the Offer
and it has not complied with any state takeover laws. See Section 11. Should
any government official or third party seek to apply any state takeover law to
the Offer, Purchaser will take such action as then appears desirable.
 
  If it is asserted that one or more state takeover laws applies to the Offer
and it is not determined by an appropriate court that such act or acts do not
apply or are invalid as applied to the Offer, the Merger Sub might be required
to file certain information with, or receive approvals from, the relevant
state authorities. In addition, if enjoined, the Merger Sub might be unable to
accept for payment any Shares tendered pursuant to the Offer, or be delayed in
consummating the Offer. In such case, the Merger Sub may not be obligated to
accept for payment any Shares tendered. See Section 13.
 
                                      29
<PAGE>
 
  Federal Reserve Board Regulations. Regulations G, T, U and X (the "Margin
Regulations") promulgated by the Federal Board place restrictions on the
amount of credit that may be extended for the purpose of purchasing margin
stock (including the Shares) if such credit is secured directly or indirectly
by margin stock. Purchaser and the Merger Sub will attempt to ensure that the
financing of the acquisition of the Shares will be in compliance with the
Margin Regulations.
 
16. FEES AND EXPENSES.
 
  Purchaser and the Merger Sub have retained Wasserstein Perella to act as the
Dealer Manager and to provide certain financial advisory services in
connection with the proposed acquisition of the Company. In connection with
such services Purchaser has agreed to pay Wasserstein Perella a transaction
fee of $1,650,000 upon consummation of the Offer. Purchaser and the Merger Sub
have agreed to reimburse Wasserstein Perella for its reasonable out-of-pocket
expenses, including the fees and expenses of its counsel, for acting as
financial advisor and Dealer Manager, and have agreed to indemnify Wasserstein
Perella against certain liabilities and expenses for acting as financial
advisor and Dealer Manager, including liabilities under the federal securities
laws.
 
  The Merger Sub has also retained Georgeson & Company Inc. to act as the
Information Agent in connection with the Offer. The Information Agent may
contact holders of Shares by mail, telephone, telex, telegraph and personal
interviews and may request brokers, dealers and other nominee stockholders to
forward materials relating to the Offer to beneficial owners of Shares. The
Information Agent will receive reasonable and customary compensation for such
services, plus reimbursement of out-of-pocket expenses and the Merger Sub will
indemnify the Information Agent against certain liabilities and expenses in
connection with the Offer, including liabilities under the federal securities
laws.
 
  The Merger Sub will pay the Depositary reasonable and customary compensation
for its services in connection with the Offer, plus reimbursement for out-of-
pocket expenses, and will indemnify the Depositary against certain liabilities
and expenses in connection therewith, including liabilities under the federal
securities laws. Brokers, dealers, commercial banks and trust companies will
be reimbursed by the Merger Sub for customary mailing and handling expenses
incurred by them in forwarding material to their customers.
 
17. MISCELLANEOUS.
 
  The Offer is not being made to (nor will tenders be accepted from or on
behalf of) holders of Shares in any jurisdiction in which the making of the
Offer or the acceptance thereof would not be in compliance with the laws of
such jurisdiction. However, the Merger Sub may, in its sole discretion, take
such action as it may deem necessary to make the Offer in any such
jurisdiction and extend the Offer to holders of Shares in such jurisdiction.
 
  Neither Purchaser nor the Merger Sub is aware of any jurisdiction in which
the making of the Offer or the acceptance of Shares in connection therewith
would not be in compliance with the laws of such jurisdiction.
 
  Purchaser and the Merger Sub have filed with the SEC a Statement on Schedule
14D-1 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 Statement and any amendments
thereto, including exhibits, may be examined and copies may be obtained from
the principal office of the SEC in the manner set forth in Section 8.
 
  No person has been authorized to give any information or make any
representation on behalf of Purchaser or the Merger Sub not contained in this
Offer to Purchase or in the Letter of Transmittal and, if given or made, such
information or representation must not be relied upon as having been
authorized.

Ladies and Gentlemen:
 
  The undersigned hereby tenders to BGN Acquisition Corp., a Delaware
corporation (the "Merger Sub") and a wholly owned subsidiary of Global
Industrial Technologies, Inc., a Delaware corporation ("Purchaser"), the
above-described shares, par value $1.00 per share (the "Common Stock"),
including the associated rights to purchase Series B Junior Participating
Preferred Stock (the "Rights" and, together with the Common Stock, the
"Shares"), of A.P. Green Industries, Inc., a Delaware corporation (the
"Company"), pursuant to the Offer to Purchase, dated March 6, 1998 (the "Offer
to Purchase"), all of the outstanding Shares at a price of $22.00 per Share,
net to the seller in cash, on the terms and subject to the conditions set
forth in the Offer to Purchase, receipt of which is hereby acknowledged, and
in this Letter of Transmittal (which, together with the Offer to Purchase,
constitute the "Offer"). The undersigned understands that the Merger Sub
reserves the right to transfer or assign, from time to time, in whole or in
part, to one or more of its affiliates, the right to purchase the Shares
tendered herewith.
 
  On the terms and subject to the conditions of the Offer (including the Offer
Conditions and together with, if the Offer is extended or amended, the terms
and conditions of such extension or amendment), subject to, and effective
upon, acceptance for payment of, and payment for, the Shares tendered herewith
in accordance with the terms of the Offer, the undersigned hereby sells,
assigns and transfers to, or upon the order of, the Merger Sub, all right,
title and interest in and to all of the Shares being tendered hereby and any
and all cash dividends, distributions, rights, other Shares or other
securities issued or issuable in respect of such Shares on or after March 3,
1998 (collectively, "Distributions"), and appoints Harris Trust and Savings
Bank (the "Depositary") the true and lawful agent and attorney-in-fact of the
undersigned with respect to such Shares (and any Distributions) with full
power of substitution (such power of attorney being deemed to be an
irrevocable power coupled with an interest) to the fullest extent of such
stockholder's rights with respect to such Shares (and any Distributions) (a)
to deliver such Share Certificates (as defined herein) (and any Distributions)
or transfer ownership of such Shares (and any Distributions) on the account
books maintained by a Book-Entry Transfer Facility, together in either such
case with all accompanying evidences of transfer and authenticity, to or upon
the order of the Merger Sub, (b) to present such Shares (and any
Distributions) for transfer on the books of the Company and (c) to receive all
benefits and otherwise exercise all rights of beneficial ownership of such
Shares (and any Distributions), all in accordance with the terms and the
conditions of the Offer.
 
  The undersigned hereby irrevocably appoints the designees of the Merger Sub,
and each of them, the attorneys-in-fact and proxies of the undersigned, each
with full power of substitution, to the full extent of such stockholder's
rights with respect to the Shares tendered hereby which have been accepted for
payment and with respect to any Distributions. The designees of the Merger Sub
will, with respect to the Shares (and any associated Distributions) for which
the appointment is effective, be empowered to exercise all voting and any
other rights of such stockholder, as they, in their sole discretion, may deem
proper at any annual, special or adjourned meeting of the Company's
stockholders, by written consent in lieu of any such meeting or otherwise.
This proxy and power of attorney shall be irrevocable and coupled with an
interest in the tendered Shares. Such appointment is effective when, and only
to the extent that, the Merger Sub deposits the payment for such Shares with
the Depositary. Upon the effectiveness of such appointment, without further
action, all prior powers of attorney, proxies and consents given by the
undersigned with respect to such Shares (and any associated Distributions)
will be revoked, and no subsequent powers of attorney, proxies, consents or
revocations may be given (and, if given, will not be deemed effective). The
Merger Sub reserves the right to require that, in order for Shares to be
deemed validly tendered, immediately upon the Merger Sub's acceptance for
payment of such Shares, the Merger Sub must be able to exercise full voting
rights with respect to such Shares (and any associated Distributions),
including voting at any meeting of stockholders.
 
  The undersigned hereby represents and warrants that the undersigned has full
power and authority to tender, sell, assign and transfer the Shares (and any
Distributions) tendered hereby and, when the same are accepted for payment by
the Merger Sub, the Merger Sub will acquire good, marketable and unencumbered
title thereto, free and clear of all liens, restrictions, charges and
encumbrances, and the same will not be subject to any adverse claim. The
undersigned will, upon request, execute and deliver any additional documents
deemed by the Depositary or the Merger Sub to be necessary or desirable to
complete the sale, assignment and transfer of the Shares (and any
Distributions) tendered hereby. In addition, the undersigned shall promptly
remit and transfer to the Depositary for the account of the Merger Sub any and
all Distributions in respect of
<PAGE>
 
the Shares tendered hereby, accompanied by appropriate documentation of
transfer; and, pending such remittance or appropriate assurance thereof, the
Merger Sub shall be entitled to all rights and privileges as owner of any such
Distributions and may withhold the entire purchase price or deduct from the
purchase price the amount or value thereof, as determined by the Merger Sub in
its sole discretion.
 
  All authority conferred or agreed to be conferred pursuant to this Letter of
Transmittal shall not be affected by, and shall survive, the death or
incapacity of the undersigned and any obligation of the undersigned hereunder
shall be binding upon the heirs, personal representatives, successors and
assigns of the undersigned. Except as stated in the Offer to Purchase, this
tender is irrevocable.
 
  The undersigned understands that the valid tender of Shares pursuant to one
of the procedures described in Section 3 of the Offer to Purchase will
constitute a binding agreement between the undersigned and the Merger Sub upon
the terms and subject to the conditions of the Offer.
 
  Unless otherwise indicated herein under "Special Payment Instructions,"
please issue the check for the purchase price and/or return any certificates
for Shares not tendered or accepted for payment in the name(s) of the
registered owner(s) appearing under "Description of Shares Tendered."
Similarly, unless otherwise indicated under "Special Delivery Instructions,"
please mail the check for the purchase price and/or return any certificates
for Shares not tendered or accepted for payment (and accompanying documents,
as appropriate) to the address(es) of the registered owner(s) appearing under

Instructions and the Special Payment Instructions are completed, please issue

tendered or accepted for payment (and any accompanying documents, as
appropriate) in the name of, and deliver such check and/or return such
certificates (and any accompanying documents, as appropriate) to, the person
or persons so indicated. The undersigned recognizes that the Merger Sub has no
obligation pursuant to the Special Payment Instructions to transfer any Shares
from the name of the registered owner thereof if the Merger Sub does not
accept for payment any of the Shares so tendered.

  2. DELIVERY OF LETTER OF TRANSMITTAL AND CERTIFICATES OR BOOK-ENTRY
CONFIRMATIONS. This Letter of Transmittal is to be used either if certificates
are to be forwarded herewith or if tenders are to be made pursuant to the
procedures for tender by book-entry transfer set forth in Section 3 of the
Offer to Purchase. Certificates for all physically tendered Shares ("Share
Certificates"), or confirmation of any book-entry transfer into the
Depositary's account at one of the Book-Entry Transfer Facilities of Shares
tendered by book-entry transfer, as well as this Letter of Transmittal
properly completed and duly executed with any required signature guarantees,
and any other documents required by this Letter of Transmittal, must be
received by the Depositary at one of its addresses set forth herein on or
prior to the Expiration Date (as defined in the Offer to Purchase).
  Stockholders whose certificates for Shares are not immediately available or
who cannot deliver all other required documents to the Depositary on or prior
to the Expiration Date or who cannot comply with the procedures for book-entry
transfer on a timely basis may nevertheless tender their Shares by properly
completing and duly executing a Notice of Guaranteed Delivery pursuant to the
guaranteed delivery procedure set forth in Section 3 of the Offer to Purchase.
Pursuant to such procedure: (i) such tender must be made by or through an
Eligible Institution; (ii) a properly completed and duly executed Notice of
Guaranteed Delivery substantially in the form provided by the Purchaser must
be received by the Depositary prior to the Expiration Date; and (iii) Share
Certificates or confirmation of any book-entry transfer into the Depositary's
account at a Depository Institution of Shares tendered by book-entry transfer,
as well as a Letter of Transmittal, properly completed and duly executed with
any required signature guarantees (or, in the case of a book-entry transfer,
an Agent's Message), and all other documents required by this Letter of
Transmittal, must be received by the Depositary within three New York Stock
Exchange trading days after the date of execution of such Notice of Guaranteed
Delivery.
  If Share Certificates are forwarded separately to the Depositary, a properly
completed and duly executed Letter of Transmittal must accompany each such
delivery.
  THE METHOD OF DELIVERY OF SHARE CERTIFICATES AND ALL OTHER REQUIRED
DOCUMENTS, INCLUDING DELIVERY THROUGH ANY BOOK-ENTRY TRANSFER FACILITY, IS AT
THE ELECTION AND RISK OF THE TENDERING STOCKHOLDER. THE DELIVERY WILL BE
DEEMED MADE ONLY WHEN ACTUALLY RECEIVED BY THE DEPOSITARY (INCLUDING, IN THE
CASE OF A BOOK-ENTRY TRANSFER, BY BOOK-ENTRY CONFIRMATION). IF SUCH DELIVERY
IS BY MAIL, IT IS RECOMMENDED THAT SUCH CERTIFICATES AND DOCUMENTS BE SENT BY
REGISTERED MAIL, PROPERLY INSURED, WITH RETURN RECEIPT REQUESTED. IN ALL
CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ASSURE TIMELY DELIVERY.
 
  No alternative, conditional or contingent tenders will be accepted and no
fractional Shares will be purchased. All tendering stockholders, by execution
of this Letter of Transmittal (or facsimile thereof), waive any right to
receive any notice of the acceptance of their Shares for payment.

"Number of Shares Tendered." In such cases, new certificate(s) for the
remainder of the Shares that were evidenced by the old certificate(s) will be
sent to the registered owner, unless otherwise provided in the appropriate box
on this Letter of Transmittal, as soon as practicable after the Expiration
Date. All Shares represented by certificates delivered to the Depositary will
be deemed to have been tendered unless otherwise indicated.
 
  5. SIGNATURES ON LETTER OF TRANSMITTAL; STOCK POWERS AND ENDORSEMENTS. If
this Letter of Transmittal is signed by the registered owners of the Shares
tendered hereby, the signature must correspond with the names as written on
the face of the certificates without alteration, enlargement or any other
change whatsoever.

joint owners, all such owners must sign this Letter of Transmittal.
 
  If any of the tendered Shares are registered in different names on several
certificates, it will be necessary to complete, sign and submit as many
separate Letters of Transmittal as there are different registrations of
certificates.

by trustees, executors, administrators, guardians, attorneys-in-fact, officers
of corporations or others acting in a fiduciary or representative capacity,
such persons should so indicate when signing, and proper evidence satisfactory
to the Parent of their authority so to act must be submitted.

Shares listed and transmitted hereby, no endorsements of certificates or
separate stock powers are required unless payment is to be made to, or

in the name of, a person other than the registered owner(s). Signatures on
such certificates or stock powers must be guaranteed by an Eligible
Institution.
 
  If this Letter of Transmittal is signed by a person other than the
registered owner of the certificate(s) listed, the certificate(s) must be
endorsed or accompanied by the appropriate stock powers, in either case signed
exactly as the name or names of the registered owner or holders appears on the
certificate(s). Signatures on such certificates or stock powers must be
guaranteed by an Eligible Institution.
 
  6. STOCK TRANSFER TAXES. The Merger Sub will pay any stock transfer taxes
with respect to the transfer and sale of Shares to it or its order pursuant to
the Offer. If, however, payment of the purchase price is to be made to, or (in
the circumstances permitted hereby) if certificates for Shares not tendered or
accepted for payment are to be registered in the name of, any person other
than the registered owner, or if tendered certificates are registered in the
name of any person other than the person(s) signing this Letter of
Transmittal, the amount of any stock transfer taxes (whether imposed on the
registered owner or such person) payable on account of the transfer to such
person will be deducted from the purchase price if satisfactory evidence of
the payment of such taxes, or exemption therefrom, is not submitted.
 
  EXCEPT AS PROVIDED IN THIS INSTRUCTION 6, IT WILL NOT BE NECESSARY FOR
TRANSFER TAX STAMPS TO BE AFFIXED TO THE CERTIFICATES LISTED IN THIS LETTER OF
TRANSMITTAL.
 
  7. SPECIAL PAYMENT AND DELIVERY INSTRUCTIONS. If a check is to be issued in
the name of, and/or certificates for Shares not tendered or accepted for
payment are to be issued or returned to, a person other than the signer of
this Letter of Transmittal or if a check and/or such certificates are to be
mailed to a person other than the signer of this Letter of Transmittal or to
an address other than that shown above, the appropriate boxes on this Letter
of Transmittal should be completed.

  9. SUBSTITUTE FORM W-9. Each tendering stockholder is required to provide
the Depositary with a correct Taxpayer Identification Number ("TIN"),
generally the stockholder's social security or federal employer identification
number, on Substitute Form W-9 below. Failure to provide the information on
the form may subject the tendering stockholder to 31% federal income tax
backup withholding on the payment of the purchase price. The box in Part 3 of
the form may be checked if the tendering stockholder has not been issued a TIN
and has applied for a TIN or intends to apply for a TIN in the near future. If
the box in Part 3 is checked and the Depositary is not provided with a TIN
within 60 days, the Depositary will withhold 31% of all payments of the
purchase price thereafter until a TIN is provided to the Depositary.
 
  IMPORTANT: THIS LETTER OF TRANSMITTAL (TOGETHER WITH SHARE CERTIFICATES OR
CONFIRMATION OF BOOK-ENTRY TRANSFER AND ALL OTHER REQUIRED DOCUMENTS) OR THE
NOTICE OF GUARANTEED DELIVERY MUST BE RECEIVED BY THE DEPOSITARY PRIOR TO THE
EXPIRATION DATE.
 
                           IMPORTANT TAX INFORMATION
 
  Under the federal income tax law, a stockholder whose tendered Shares are
accepted for purchase is required by law to provide the Depositary (as payer)
with such stockholder's correct TIN on Substitute Form W-9 below and to
certify that such TIN is correct (or that such stockholder is awaiting a TIN)
or otherwise establish a basis for exemption from backup withholding. If such
stockholder is an individual, the TIN is his or her social security number. If
a stockholder fails to provide a TIN to the Depositary, such stockholder may
be subject to a $50 penalty imposed by the Internal Revenue Service. In
addition, payments that are made to such stockholder with respect to Shares
purchased pursuant to the Offer may be subject to backup withholding of 31%
(see below).
 
  Certain stockholders (including, among others, all corporations and certain
foreign individuals) are not subject to these backup withholding and reporting
requirements. In order for a foreign individual to qualify as an exempt
recipient, that stockholder must generally submit a Form W-8, signed under
penalties of perjury, attesting to that individual's exempt status. A Form W-8
can be obtained from the Depositary. See the enclosed Guidelines for
Certification of Taxpayer Identification Number on Substitute Form W-9 for
additional instructions.
 
  If backup withholding applies, the Depositary is required to withhold 31% of
any payments made to the stockholder or payee. Backup withholding is not an
additional tax. Rather, the tax liability of persons subject to backup
withholding will be reduced by the amount of tax withheld. If withholding
results in an overpayment of taxes, a refund may be obtained from the Internal
Revenue Service.
 
  The box in Part 3 of the Substitute Form W-9 may be checked if the tendering
stockholder has not been issued a TIN and has applied for a TIN or intends to
apply for a TIN in the near future. If the box in Part 3 is checked, the
stockholder or other payee must also complete the Certification of Awaiting
Taxpayer Identification Number below in order to avoid backup withholding. If
a stockholder's TIN is provided to the Depositary within 60 days of the date
of the Substitute Form W-9, payment will be made to such stockholder without
the imposition of backup withholding. If a stockholder's TIN is not provided
to the Depositary within such 60-day period, the Depositary will make such
payment, subject to backup withholding.
 
PURPOSE OF SUBSTITUTE FORM W-9
 
  To prevent backup withholding on payments made to a stockholder whose
tendered Shares are accepted for purchase, the stockholder is required to
notify the Depositary of its correct TIN by completing Substitute Form W-9
certifying that the TIN provided on such Form is correct (or that such
stockholder is awaiting a TIN, in which case the stockholder should check the
box in Part 3 of the Substitute Form W-9) and that (A) such stockholder is
exempt from backup withholding, (B) such stockholder has not been notified by
the Internal Revenue Service that such stockholder is subject to backup
withholding as a result of failure to report all interest or dividends or (C)
the Internal Revenue Service has notified the stockholder that the stockholder
is no longer subject to backup withholding. The stockholder must sign and date
the Substitute Form W-9 where indicated, certifying that the information on
such Form is correct.
<PAGE>
 
  Alternatively, a stockholder that qualifies as an exempt recipient (other
than a stockholder required to complete Form W-8 as described above) should
write "Exempt" in Part 1 of the Substitute Form W-9, enter its correct TIN and
sign and date such Form where indicated.
 
WHAT NUMBER TO GIVE THE DEPOSITARY
 
  The stockholder is required to give the Depositary the social security
number or employer identification number of the record owner of the Shares or
of the last transferee appearing on the transfers attached to, or endorsed on,
the Shares. If the Shares are in more than one name or are not in the name of
the actual owner, consult the enclosed Guidelines for Certification of
Taxpayer Identification Number on Substitute Form W-9 for additional guidance
on which number to report.

              GLOBAL INDUSTRIAL TECHNOLOGIES TO ACQUIRE A.P. GREEN
              ----------------------------------------------------

 -COMBINATION OF HARBISON-WALKER AND A.P. GREEN TO CREATE LEADING REFRACTORIES
  ---------------------------------------------------------------------------
BUSINESS IN WESTERN HEMISPHERE: GENERATE OPPORTUNITIES FOR ECONOMIES OF SCALE-
- -----------------------------------------------------------------------------  

- -COMPANY ALSO SIGNS DEFINITIVE AGREEMENT FOR SALE OF INTOOL FOR $217.5MILLION- 
- ----------------------------------------------------------------------------  

DALLAS, TX, March 4, 1998 --  Global Industrial Technologies, Inc. (NYSE: GIX)
announced today that it has signed a definitive agreement to purchase for cash
all outstanding shares of A.P. Green Industries, Inc. (NYSE: APK) at $22 per
share, or approximately $195 million.  The Company also said it signed a
definitive agreement for the previously announced sale of its Industrial Tool
business to Cooper Industries (NYSE:CBE) of Houston, Texas, for $217.5 million.

"These transactions further our efforts to create one of the world's leading
refractories companies, and sharpen our focus on industrial businesses in which
we see strong opportunities for substantial future profit growth," said J.L.
Jackson, Chairman and Chief Executive of Global Industrial Technologies.  "A.P.
Green also brings to Global an attractive and profitable lime business, which
makes up 38% of their operating income and will provide product diversity after
integration into our Minerals operation."

"With the sale of INTOOL for a price of approximately nine times EBITDA, we have
created significant value, which we will redeploy into a major opportunity to
expand the profit potential, and growth of our Harbison-Walker subsidiary,"
Jackson said.  "The critical mass we will possess in that business, our proven
ability to operate as a low-cost producer, and the economies of scale and
synergies we expect to achieve as a result of the combination will help us
generate enhanced returns from this business.  As a result of these benefits, we
expect our acquisition of Green to be modestly accretive to earnings in fiscal
1998, and significantly accretive to earnings in 1999 and beyond notwithstanding
a restructuring charge associated with this transaction.  Further, we expect
profit contributions from this acquisition to build as we integrate Green's
operations with Harbison-Walker's over the next two years.  Once fully
integrated, we believe that annual
<PAGE>
 
cost reductions in the range of $15-$20 million are achievable after an assumed
potential 15% reduction of A.P. Green's sales."

"The decisions we announce today were arrived at following an extensive
evaluation of our businesses both with resources within the Company and with
outside consultants, together with a full review of all options that could help
us deliver the greatest possible value to shareholders," continued Jackson.
"Our major presence in the refractories market, together with our forged
products business and its exciting new undercarriage operation, represent a
solid core from which to build returns for shareholders."

Global's acquisition of Green, which will be effected by means of a tender
offer, was approved unanimously by the Boards of Directors of both companies.
The tender offer will commence within five business days and once initiated,
will be open for 20 business days unless further extended.  Global's tender
offer is conditioned upon, among other things, customary regulatory approvals
and there being validly tendered and not withdrawn at least a majority of the
outstanding shares of A.P. Green.  After the consummation of the tender offer,
Global has agreed to acquire any of the remaining outstanding shares of Green
pursuant to a second-step merger in which holders of such shares will receive
$22 per share.

Juan Bravo, president of Harbison-Walker stated:  "We are very excited about the
prospects of the Harbison-Walker/Green operation.  The combined business will
operate plants in 6 countries around the world, with revenues of more than $650
million.  We believe that together, the management and employees of the combined
company can create significant value for Global shareholders."

Wasserstein Perella is the Financial Advisor for Global Industrial Technologies
in its acquisition of A.P. Green.  Offering materials will be available from the
Information Agent, Georgeson & Company Inc.  The depositary for the offer is
Harris Trust and Savings Bank.

A.P. Green, with headquarters in Mexico, Mo., reported sales and operating
revenues of $277.9 million last year.  It has 22 plants located in the U.S.,
Canada, Mexico, Colombia, the U.K. and Indonesia, manufacturing refractory
products used in the processing of steel and other metals, chemicals, glass,
ceramics, paper and cement.  A.P. Green also produces lime used in the
manufacture of steel, aluminum, pulp and paper processing, soil stabilization
for road construction, and water purification.

The Company expects to close its sale of INTOOL to Cooper Industries by the end
of the calendar first quarter.  INTOOL reported sales of $113.2 million and
operating earnings of $19.7 million for 1997.  Cooper is a global, diversified,
manufacturer of electrical products, tools and hardware, and automotive products
with 1997 revenues of

                                      -2-
<PAGE>
 
$5.3 billion.  INTOOL will become a part of Cooper Power Tools Division.  "From
what was a small division of Dresser Industries, we have built a profitable and
thriving business at INTOOL through internal growth, our 1995 acquisition of
Rotor Tool, and our establishment of a new start-up division, ITD Automation,"
said Jackson.  "We are pleased that the managers and employees of INTOOL are
becoming part of a company that recognizes the value of INTOOL's brands,
products and people and are committed to being a leader in the industrial tool
business."

Global Industrial Technologies is a major manufacturer of technologically
advanced industrial products that support high-growth markets around the world.
Its Harbison-Walker subsidiary operates 15 refractory plants in five countries,
including the United States, Canada, Mexico, Chile and Germany.

harbor provisions of the Private Securities Litigation Reform Act of 1995.
Although the Company believes the expectations reflected in such forward-looking
statements are based on reasonable assumptions, it can give no assurance that
its expectations will be realized.  Forward-looking statements involve known and

such notice of withdrawal must specify the name of the person having tendered
the Shares to be withdrawn, the number of Shares to be withdrawn and the names
in which the certificate(s) evidencing the Shares to be withdrawn are
registered, if different from that of the person who tendered such Shares.  If
certificates for Shares to be withdrawn have been delivered or otherwise
identified to the Depositary,  the name of the registered holder and the serial
numbers of the particular certificates evidencing the Shares to be withdrawn
must also be furnished to the Depositary as aforesaid prior to the physical
release of such certificates and, unless such Shares have been tendered for the
account of any Eligible Institution (as defined in Section 3 of the Offer to
Purchase), the signature on the notice of withdrawal must be guaranteed by an
Eligible Institution.  If Shares have been tendered pursuant to the procedures
for book-entry transfer as set forth in Section 3 of the Offer to Purchase, any
notice of withdrawal must specify the name and number of the account at the
Book-Entry Transfer Facility to be credited with the withdrawn Shares and
otherwise comply with such Book-Entry Transfer Facility's procedures for such
withdrawal, in which case a notice of withdrawal will be effective if delivered
to the Depositary in writing.  Withdrawals of tenders of Shares may not be
rescinded, and any Shares properly withdrawn will thereafter be deemed not
validly tendered for the purposes of the Offer. However, withdrawn Shares may be
retendered by again following one of the procedures described in Section 3
of the Offer to Purchase at any time on or prior to the Expiration Date.

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

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

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

validity (including time of receipt) of any notice of withdrawal will be
determined by the Merger Sub, in its sole discretion, which determination shall
be final and binding.  The Merger Sub will not pay any fees or commissions to
any broker or dealer or any other person (other than the Dealer Manager) for
soliciting tenders of Shares pursuant to the Offer.

PAYEES EXEMPT FROM BACKUP WITHHOLDING
The following is a list of payees specifically exempted from backup
withholding depending upon the type of payment (see below):
 (1) A corporation.
 (2) An organization exempt from tax under section 501(a), or an IRA or a
     custodial account under section 403(b)(7).
 (3) The United States or any agency or instrumentality thereof.
 (4) A State, the District of Columbia, a possession of the United States, or
     any subdivision or instrumentality thereof.
 (5) A foreign government, a political subdivision of a foreign government,
     or any agency or instrumentality thereof.
 (6) An international organization or any agency or instrumentality thereof.
 (7) A foreign central bank of issue.
 (8) A dealer in securities or commodities required to register in the U.S.
     or a possession of the U.S.
 (9) A futures commission merchant registered with the Commodity Futures
     Trading Commission.
 (10) A real estate investment trust.
 (11) An entity registered at all times during the tax year under the
      Investment Company Act of 1940.
 (12) A common trust fund operated by a bank under section 584(a).
 (13) A financial institution.
 (14) A middleman known in the investment community as a nominee or listed in
      the most recent publication of the American Society of Corporate
      Secretaries, Inc., Nominee List.
 (15) A trust exempt from tax under section 664 or described in section 4947.
For Interest and dividends, all listed payees are exempt except item (9). For
broker transactions, payees listed in items (1) through (13) and a person
registered under the Investment Advisers Act of 1940 who regularly acts as a
broker are exempt.
 
Exempt payees described above should file Form W-9 to avoid possible erroneous
backup withholding. FILE THIS FORM WITH THE PAYER, FURNISH YOUR TAXPAYER
IDENTIFICATION NUMBER, WRITE "EXEMPT" IN PART 1 OF THE FORM, AND RETURN IT TO
THE PAYER. If you are a nonresident alien or a foreign entity not subject to
backup withholding, give the payer a completed Form W-8, Certificate of
Foreign Status.
 
PRIVACY ACT NOTICE. Section 6109 requires most recipients of dividend,
Interest, or other payments to give taxpayer identification numbers to payers
who must report the payments to IRS. The IRS uses the numbers for
identification purposes. Payers must be given the numbers whether or not
recipients are required to file tax returns. Payers must generally withhold
31% of taxable Interest, dividend, and certain other payments to a payee who
does not furnish a taxpayer identification number to a payer. Certain
penalties may also apply.
 
PENALTIES
(1) FAILURE TO FURNISH TAXPAYER IDENTIFICATION NUMBER. If you fail to furnish
your correct taxpayer identification number to a payer, you are subject to a
penalty of $50 for each such failure unless your failure is due to reasonable
cause and not to willful neglect.
(2) CIVIL PENALTY FOR FALSE INFORMATION WITH RESPECT TO WITHHOLDING. If you
make a false statement with no reasonable basis which results in no imposition
of backup withholding, you are subject to a penalty of $500.
(3) CRIMINAL PENALTY FOR FALSIFYING INFORMATION. Willfully falsifying
certifications or affirmations may subject you to criminal penalties including
fines and/or Imprisonment.
FOR ADDITIONAL INFORMATION CON- TACT YOUR TAX CONSULTANT OR THE INTERNAL
REVENUE SERVICE.

               ------------------------                                        
Section 2.4 shall automatically constitute a warranty by the Company to the

Agent and each Lender to the effect that, on the date of such requested
conversion, no Event of Default or unmatured Event of Default shall have then
occurred and be continuing.

          2.6  Conditions.  Notwithstanding any other provision of this
               ----------                                              
Agreement, no Lender shall be obligated to make any Loan, or to convert into or
permit the continuation at the end of the applicable Interest Period of any
Eurodollar Loan, if an Event of Default or Unmatured Event of Default exists or
would result therefrom.

          2.7  Pro Rata Treatment.  All borrowings, conversions and repayments
               ------------------

               -------------------                                      
requested Loan on any date shall not relieve any other Lender of its obligation
(if any) to make a Loan on such date, but no Lender shall be responsible for the
failure of any other Lender to make any Loan to be made by such other Lender.

          2.9  Extension of the Termination Date.
               ---------------------------------

<PAGE>
 
          Agent, request that each Lender agree to extend the then-scheduled
          Termination Date by 364 days.

               (b) The Agent shall, upon receipt of any such extension request,
          promptly notify each Lender thereof, and request that each Lender
          promptly advise the Agent of its approval or rejection of such
          request.

               (c) Upon receipt of such notification from the Agent, each Lender
          may, in its sole discretion, agree to extend for 264 days, or decline
          to extend, the Termination Date, and each Lender shall, within 30 days
          of receipt of the notice described in clause (b), notify the Agent of
                                                ----------
          its approval or denial of such request. If any Lender does not so
          notify the Agent, such Lender shall be deemed to have denied such
          extension request. The Agent shall, no later than 45 days following
          its receipt of any extension request from the Company, notify the
          Company as to the Lenders which have approved or denied such request.

               (d) If all of the Lenders approve any such request, the
          Termination Date shall be extended to the date which is 364 days after
          the Termination Date in effect immediately prior to such extension. If
          fewer than all of the Lenders approve any such request, the
          Termination Date shall not be extended.

          -----
note (as amended, supplemented, replaced or otherwise modified from time to
time, individually each a "Note" and collectively for all Lenders the "Notes")
substantially in the form set forth in Exhibit A, with appropriate insertions,
                                       ---------
dated the Effective Date (or such other date as shall be satisfactory to the
Agent), payable to the order of such Lender in the principal amount of the
Commitment of such Lender (or, if less, in the aggregate unpaid principal amount
of such Lender's Loans) on the Termination Date.

                                      -21-

          3.2  Recordkeeping.  Each Lender shall record in its records, or at
               -------------                                                 
its option on the schedule attached to its Note, the date and amount of each
Loan made by such Lender, each repayment or conversion thereof and, in the case
of each Eurodollar Loan, the dates on which each Interest Period for such loan
shall begin and end.  The aggregate unpaid principal amount so recorded shall be
rebuttable presumptive evidence of the principal amount owing and unpaid on such
Note.  The failure to so record any such amount or any error in so recording any
such amount shall not, however, limit or otherwise affect the obligations of the
Company hereunder or under any Note to repay the principal amount of the Loans
evidenced by such Note together with all interest accruing thereon.

          SECTION 4  INTEREST.

          4.1  Interest Rates.  The Company promises to pay interest on the
               --------------                                              
unpaid principal amount of each Loan for the period commencing on and including
the date of such Loan to but excluding the date such Loan is paid in full, as
follows:

               (a) at all times while such Loan is a Floating Rate Loan, at a
     rate per annum equal to the Alternate Reference Rate from time to time in
     effect; and

               (b) at all times while such Loan is a Eurodollar Loan, at a rate
     per annum equal to the Eurodollar Rate (Reserve Adjusted) applicable to
     each Interest Period for such Loan plus the Margin from time to time in
     effect;

provided, however, that if any principal of any Loan is not paid when due
- --------  -------                                                        
(whether by acceleration or otherwise), such principal shall bear interest, from
the due date thereof until paid in full, at a rate per annum equal to the sum of
the Alternate Reference Rate from time to time in effect (but not less than the
applicable interest rate in effect for such Loan at such due date) plus 2%.

          4.2  Interest Payment Dates.  Accrued interest on each Floating Rate
               ----------------------                                         
Loan shall be payable on the last day of each calendar quarter and at maturity.
Accrued interest on each Eurodollar Loan shall be payable on the last day of
each Interest Period relating to such Loan and at maturity.

                                      -22-
<PAGE>
 
After maturity, accrued interest on all Loans shall be payable on demand.

          4.3  Interest Periods.  Each "Interest Period" for a Eurodollar Loan
               ----------------                                               
shall commence on the date such Eurodollar Loan is made or converted from a
Floating Rate Loan, or on the expiration of the immediately preceding Interest
Period for such Eurodollar Loan, and shall end on the date which is one, two or
three months thereafter, as the Company may specify:

               (a) in the case of an Interest Period which commences on the date
     of Eurodollar Loan is made or converted from a Floating Rate Loan, in the
     related notice or borrowing or conversion pursuant to Section 2.3 or 2.4,
                                                           -----------    --- 
     or

               (b) in the case of succeeding Interest Period with respect to any
     Eurodollar Loan, by written or telephonic notice to the Agent not later
     than 10:00 a.m., Chicago time, at least three Business Days prior to the
     first day of such succeeding Interest Period, it being understood that (i)
     each such notice shall be effective upon receipt by the Agent (which shall
     promptly advise each Lender thereof) and (ii) if the Company fails to give
     such notice, such Loan shall automatically become a Floating Rate Loan at
     the end of its then-current Interest Period.

Each Interest Period for a Eurodollar Loan that begins on the last day of a
calendar month (or on a day for which there is no numerically corresponding day
in the appropriate subsequent month) shall end on the last Business Day of the
appropriate subsequent calendar month.  Each Interest Period for a Eurodollar
Loan which would otherwise end on a day which is not a Business Day shall end on
the immediately succeeding Business Day (unless such immediately succeeding
Business Day is the first Business Day of a calendar month, in which case such
Interest Period shall end on the immediately preceding Business Day).  The
Company may not select any Interest Period which would end after the scheduled
Termination Date.

          4.4  Setting and Notice of Eurodollar Rates.  The applicable
               --------------------------------------                 
Eurodollar Rate for each Interest Period shall be determined by the Agent, and
notice thereof shall be given

                                      -23-
<PAGE>
 
by the Agent promptly to the Company and each Lender.  Each determination of the
applicable Eurodollar Rate by the Agent shall be conclusive and binding upon the
parties hereto, in the absence of demonstrable error.  The Agent shall, upon
written request of the Company or any Lender, deliver to the Company or such
Lender a statement showing the computations used by the Agent in determining any
applicable Eurodollar Rate hereunder.

          4.5  Computation of Interest.  Interest shall be computed for the
               -----------------------                                     
actual number of days elapsed on the basis of a year of 160 days.  The
applicable interest rate for each Floating Rate Loan shall change simultaneously
with each change in the Alternate Reference Rate.

          4.6  Limitation on Interest.  It is the intention of the parties
               ----------------------                                     
hereto to conform strictly to applicable usury laws and, anything herein or in
any Note to the contrary notwithstanding, the obligations of the Company to each
Lender under this Agreement and any Note shall be subject to the limitation that
payments of interest shall not be required to the extent that receipt thereof
would be contrary to provisions of law applicable to such Lender limiting rates
of interest which may be charged or collected by such Lender.  Accordingly, if
the transactions contemplated hereby or by any Note would be usurious under any
applicable law, rule, regulation, order or decree (or other requirement having
the force of law) of any governmental authority, court or other tribunal
(including the Federal and state laws of the United States of America or of any
other jurisdiction whose laws may be mandatorily applicable) (collectively,
"Applicable Law") with respect to any Lender, then, in that event,
notwithstanding anything to the contrary in this Agreement or any Note, it is
agreed as follows:

               (a) the following provisions of this Section 4.6 shall govern and
                                                    -----------                 
     control;

               (b) the aggregate of all consideration that constitutes interest
     under Applicable Law that is contracted for, charged or received under this
     Agreement or under any Note by any Lender shall under no circumstances
     exceed the maximum amount of interest allowed by Applicable Law (such
     maximum, nonusurious interest rate that may, under Applicable Law, be
     contracted for, charged or

                                      -24-
<PAGE>
 
     received, the "Highest Lawful Rate"), and any excess shall be credited to
     the Company by such Lender (or, if such consideration shall have been
     finally paid in full, such excess refunded to the Company by such Lender);

               (c) all sums paid, or agreed to be paid, to any Lender for the
     use, forbearance and detention of the indebtedness of the Company to such
     Lender hereunder or under any Note shall, to the extent permitted by
     Applicable Law, be amortized, prorated, allocated and spread throughout the
     full term of such indebtedness until payment in full of such indebtedness
     so that the actual rate of interest is uniform throughout the full term
     thereof;

               (d) if at any time the interest provided pursuant to Section 4.1,
                                                                    ----------- 
     together with any fees payable to any Lender pursuant to this Agreement or
     any Note that are deemed to be interest under Applicable Law, exceeds that
     amount which would have accrued to such Lender at the Highest Lawful Rate,
     the amount of interest and any such fees to accrue pursuant to this
     Agreement or any Note shall be limited, notwithstanding anything to the
     contrary in this Agreement or any Note, to the amount which would have
     accrued at the Highest Lawful Rate, but any subsequent reductions in the
     amount of such interest and/or fees, as applicable, which would otherwise
     occur shall not reduce the interest to accrue to such Lender pursuant to
     this Agreement and the applicable Note below the Highest Lawful Rate until
     the total amount of interest accrued pursuant to this Agreement and such
     Note and such fees that are deemed to be interest equals the amount of
     interest which would have accrued to such Lender if a varying rate per
     annum equal to the rate provided pursuant to Section 4.1 had at all times
                                                  -----------                 
     been in effect, plus the amount of fees which would have been received but
                     ----                                                      
     for the effect of this Section 4.6; and
                            -----------     

               (e) if the total amount of interest paid or accrued, together
     with any fees payable pursuant to this Agreement and any Note that are
     deemed to

                                      -25-
<PAGE>
 
     be interest under Applicable Law, pursuant to this Agreement and any Note
     under the foregoing provisions of this Section 4.6, is less than the total
                                            -----------                        
     amount of interest which would have accrued if a varying rate per annum
     equal to the rate provided pursuant to Section 4.1 had at all times been in
                                            -----------                         
     effect and all fees provided for in this Agreement and such Note had been
     paid, then the Company agrees to pay to the applicable Lender, upon demand,
     an amount equal to the difference between (i) the lesser of (A) the amount
     of interest and fees which would have accrued if the Highest Lawful Rate
     had at all times been in effect, and (B) the amount of interest and fees
     which would have accrued if a varying rate per annum equal to the rate
     provided pursuant to Section 4.1 had at all times been in effect and all
                          -----------                                        
     fees provided for in this Agreement and the applicable Note had been paid
     and (ii) the amount of interest and fees paid in accordance with the other
     provisions of this Agreement and the applicable Note.

For purposes of Article 5069-1.04, Vernon's Texas Civil Statutes, to the extent,
if any, applicable to any lender, the Company agrees that the Highest Lawful
Rate shall be the "indicated (weekly) rate ceiling" as defined in said Article;
provided that any Lender may also rely, to the extent permitted by Applicable
- --------                                                                     
Law, on alternative maximum rates of interest, if greater, under other
Applicable Laws; provided, further, that to the extent permitted by such
                 --------  -------                                      
Article, any Lender by notice to the Company may revise the aforesaid election
of such interest rate ceiling as such ceiling affect the then current or future
balances outstanding under this Agreement and any Note.  Chapter 15, Subtitle 3,
Title 79, of the Revised Civil Statutes of Texas, 1925 (relating to revolving
loans and triparty accounts), shall not apply to this Agreement or any Note.

          5.1.  Non-Use Fee.  The Company agrees to pay to the Agent for the
                -----------                                                 
account of each Lender a non-use fee for the period from and including the
Effective Date to but excluding the Termination Date in an amount equal to the
Specified Percentage (as defined below) per annum of the daily average of the
unused amount of such Lender's

<PAGE>
 
Commitment.  Such non-use fee shall be payable in arrears on the last day of
each calendar quarter and on the Termination Date for any period then ending for

of 360 days.

          For purposes of the foregoing, "Specified Percentage" means (a) if the
Interest Coverage Ratio is equal to or greater than 3.75 to 1, 0.10%, (b) if the
Interest Coverage Ratio is equal to or greater than 2.5 to 1 but less than .375
to 1, 0.125%, and (c) if the Interest Coverage Ratio is less than 2.5 to 1,

on the Interest Coverage Ratio as of the last day of such fiscal quarter; it
being understood that if the Company fails to deliver the financial statements

shall be 0.175% until such financial statements are delivered.

          5.2  Agent's Fee.  The Company agrees to pay to the Agent for its own
               -----------

               ------                                                         
all rights of set-off and bankers' lien provided by applicable law, and in
addition thereto, the Company agrees that at any time any Unmatured Event of
Default described in Section 12.1.4 or any Event of Default exists, the Agent
                     --------------                                          
and each Lender may apply to the payment of any obligations of the Company
hereunder any and all balances, credits, deposits, accounts or moneys of the
Company then or thereafter with the Agent or such Lender.

          7.5  Proration of Payments.  If any Lender shall obtain any payment or
               ---------------------                                            
other recovery (whether voluntary, involuntary, by application of offset or
otherwise) on account of principal of or interest on any Note in excess of its
pro rata share of payments and other recoveries obtained by all Lenders on
account of principal of and interest on all Notes (other than any non-pro rata
interest payment resulting from a Loan being an Affected Loan or as a result of
replacement of a Lender pursuant to Section 8.7), such Lender shall purchase
                                    -----------                             
from the other Lenders such participation in the Notes held by them as shall be
necessary to cause such purchasing Lender to share the excess payment or other
recovery ratably with each of them; provided, however, that if all or any
                                   ---------  -------                    
portion of the excess payment or other recovery is thereafter recovered from
such purchasing Lender, the purchase shall be rescinded and the purchase price
restored to the extent of such recovery.

          7.6  Taxes.
               ----- 

               (a)  All payments by the Company of principal, interest, fees,
          indemnities and other amounts payable hereunder and under the Notes
          shall be made to the recipient thereof without setoff or counterclaim
          and free and clear of, and without withholding or deduction for or on
          account of, any present or future Taxes (other than Excluded Taxes (as
          defined below)) now or hereafter imposed on such recipient or its
          income, property, assets or franchises (such recipient's "Recipient
          Taxes"), except to the extent that such withholding or deduction (i)
          is required by applicable law, (ii) results from the breach by such
          recipient of its Exemption Agreement (as

                                      -29-
<PAGE>
 
          defined below) or (iii) would not be required if such recipient's
          Exemption Representation (as defined below) were true. If any such
          withholding or deduction is required by applicable law, the Company
          will:

               (A) pay to the relevant authorities the full amount so required
            to be withheld or deducted;

               (B) promptly forward to the Agent an official receipt or other
            documentation satisfactory to the Agent evidencing such payment to
            such authorities; and

               (C) except to the extent that such withholding or deduction
            results from the breach, by the recipient of a payment, of its
            Exemption Agreement or would not be required if such recipient's
            Exemption Representation were true, pay to the Agent for the account
            of the relevant recipient such additional amount as is necessary to
            ensure that the net amount actually received by such recipient will
            equal the full amount such recipient would have received had no such
            withholding or deduction been required.

For the purposes of this Section 7.6, "Excluded Taxes" means, in the case of
                         -----------                                        
payments made to any Lender or the Agent, all of the following:  taxes imposed
upon the overall net income of such Lender or the Agent, franchise taxes imposed
upon such Lender or the Agent with respect to its net income by the jurisdiction
under the laws of which such Lender or the Agent, as the case may be, is
organized or any political subdivision thereof, and franchise taxes imposed upon
such Lender or the Agent with respect to its net income by the jurisdiction in
which such Lender's or the Agent's Eurodollar Office is located or any political
subdivision thereof.

               (b)  In consideration of the Company's agreements in clause (a)
                                                                    ----------
            of this Section 7.6, each Lender which is not organized under the
                    -----------
            laws of the United States or a State thereof hereby agrees (such
            Lender's "Exemption Agreement"), to the extent permitted by
            applicable law (including any

                                      -30-
<PAGE>
 
            applicable double taxation treaty of the jurisdiction of its
            incorporation and the jurisdiction in which its Eurodollar Office is
            located), to execute and deliver to the Company (i) on or before the
            first date on which any payment is to be made to such Lender
            hereunder, a United States Internal Revenue Service Form 1001 or
            4224 (or successor form), as appropriate, properly completed and
            claiming a complete exemption, from withholding or deduction for or
            on account of Recipient Taxes of such Lender, and (ii) a new Form
            1001 or 4224 (or successor form), as appropriate, upon the
            expiration or obsolescence of any previously delivered Form.

               (c) Each Lender hereby represents and warrants (such Lender's
            "Exemption Representation") to the Company that on the Effective
            Date (or, if later, the date such Lender becomes a party to this
            Agreement) it is entitled to receive payments of principal of, and
            interest on, Loans made by such Lender without withholding or
            deduction for or on account of such Lender's Recipient Taxes imposed
            by the United States of America or any political subdivision
            thereof.

            SECTION 8 INCREASED COSTS; SPECIAL PROVISIONS FOR EURODOLLAR LOANS.

            8.1  Increased Costs. (a) If, after the date hereof, the adoption of
                 ---------------
any applicable law, rule or regulation, or any change in any applicable law,
rule or regulation (including, without limitation, Regulation D of the Federal
Reserve Board), or any change in the interpre tation or administration thereof
by any governmental authority, central bank or comparable agency charged with
the interpretation or administration thereof, or compliance by any Lender (or
any Eurodollar Office of such Lender) with any request or directive (whether or
not having the force of law) of any such authority, central bank or comparable
agency

                    (A) shall subject any Lender (or any Eurodollar Office of
               such Lender) to any tax, duty or other charge with respect to its
               Eurodollar Loans, its Note or its obligation to make Eurodollar
               Loans, or shall change the

                                      -31-
<PAGE>
 
               basis of taxation of payments to any Lender of the principal of
               or interest on its Eurodollar Loans or any other amounts due
               under this Agreement in respect of its Eurodollar Loans or its
               obligation to make Eurodollar Loans (except for taxes imposed on
               or measured by the overall net income of such Lender or its
               Eurodollar Office imposed by the jurisdiction, or any political
               subdivision thereof or taxing authority therein, in which such
               Lender's principal executive office or Eurodollar Office is
               located or in which such Lender is incorporated); or

                    (B) shall impose, modify or deem applicable any reserve
               (including, without limitation, any reserve imposed by the
               Federal Reserve Board, but excluding any reserve included in the
               determination of interest rates pursuant to Section 4), special
                                                           ---------
               deposit or similar requirement against assets of, deposits with
               or for the account of, or credit extended by any Lender (or any
               Eurodollar Office of such Lender); or

                    (C) shall impose on any Lender (or its Eurodollar Office)
               any other condition affecting its Eurodollar Loans, its Note or
               its obligation to make Eurodollar Loans;

and the result of any of the foregoing is to increase the cost to (or in the
case of Regulation D referred to above, to impose a cost on) such Lender (or any
Eurodollar Office of such Lender) of making or maintaining any Eurodollar Loan,
or to reduce the amount of any sum received or receivable by such Lender (or its
Eurodollar Office) under this Agreement or under its Note with respect thereto,
then within 10 days after demand by such Lender (which demand shall be
accompanied by a statement setting forth the basis of such demand, a copy of
which shall be furnished to the Agent), the Company shall pay directly to such
Lender such additional amount or amounts as will compensate such Lender for such
increased cost or such reduction.

          (b) If any Lender shall reasonably determine that the adoption or
phase-in of any applicable law, rule or

                                      -32-
<PAGE>
 
regulation regarding capital adequacy, or any change in any applicable law, rule
or regulation, or any change in the interpretation or administration thereof by
any governmental authority, central bank or comparable agency charged with the
interpretation or administration thereof, or compliance by any Lender (or its
Eurodollar Office) or any Person controlling such Lender with any request or
directive regarding capital adequacy (whether or not having the force of law) of
any such authority, central bank or comparable agency, has or would have the
effect of reducing the rate of return on such Lender's or such controlling
Person's capital as a consequence of such Lender's obligations hereunder
(including, without limitation, such Lender's Commitment) to a level below that
which such Lender or such controlling Person could have achieved but for such
adoption, change or compliance (taking into consideration such Lender's or such
controlling Person's policies with respect to capital adequacy) by an amount
deemed by such Lender or such controlling Person to be material, then from time
to time, within 10 days after demand by such Lender (which demand shall be
accompanied by a statement setting forth the basis of such demand, a copy of
which shall be furnished to the Agent), the Company shall pay to such Lender
such additional amount or amounts as will compensate such Lender or such
controlling Person for such reduction.

          8.2  Basis for Determining Interest Rate Inadequate or Unfair.  If
               --------------------------------------------------------     
with respect to any Interest Period:

               (a) Lenders having an aggregate Percentage of 50% or more advise
the Agent that deposits in Dollars (in the applicable amounts) are not being
offered to such Lenders in the relevant market for such Interest Period, or the
Agent otherwise reasonably determines (which determination shall be binding and
conclusive on the Company) that by reason of circumstances affecting the
interbank eurodollar market adequate and reasonable means do not exist for
ascertaining the applicable Eurodollar Rate; or

               (b) Lenders having an aggregate Percentage of 50% or more advise
the Agent that the Eurodollar Rate (Reserve Adjusted) as determined by the Agent
will not adequately and fairly reflect the cost to such Lenders of maintaining
or funding such Loans for such Interest Period, or that the making or funding of
Eurodollar Loans has become

                                      -33-
<PAGE>
 
impracticable as a result of an event occurring after the date of this Agreement
which in the reasonable opinion of such Lenders materially affects such Loans,
then the Agent shall promptly notify the other parties thereof and, so long as
- ----                                                                          
such circumstances shall continue, (i) no Lender shall be under any obligation
to make or convert into Eurodollar Loans and (ii) on the last day of the current
Interest Period for each Eurodollar Loan, such Loan shall, unless then repaid in
full, automatically convert to a Floating Rate Loan.

          8.3  Changes in Law Rendering Eurodollar Loans Unlawful.  In the event
               --------------------------------------------------               
that any change in (including the adoption of any new) applicable laws or
regulations, or any change in the interpretation of applicable laws or
regulations by any governmental or other regulatory body charged with the
administration thereof, should make it (or in the good faith judgment of any
Lender cause a substantial question as to whether it is) unlawful for any Lender
to make, maintain or fund Eurodollar Loans, then such Lender shall promptly
notify each of the other parties hereto and, so long as such circumstances shall
continue, (a) such Lender shall have no obligation to make or convert into
Eurodollar Loans (but shall make Floating Rate Loans concurrently with the
making of or conversion into Eurodollar Loans by the Lenders which are not so
affected, in each case in an amount equal to such Lender's Percentage of all
Eurodollar Loans which would be made or converted into at such time in the
absence of such circumstances) and (b) on the last day of the current Interest
Period for each Eurodollar Loan of such Lender (or, in any event, if such Lender
so requests, on such earlier date as may be required by the relevant law,
regulation or interpretation), such Eurodollar Loan shall, unless then repaid in
full, automat  ically convert to a Floating Rate Loan.  Each Floating Rate Loan
made by a Lender which, but for the circumstances described in the foregoing
sentence, would be a Eurodollar Loan (an "Affected Loan") shall, notwithstanding
any other provision of this Agreement, remain outstanding for the same period as
the Group of Eurodollar Loans of which such Affected Loan would be a part absent
such circumstances.

          8.4  Funding Losses.  The Company agrees that, upon demand by any
               --------------                                              
Lender (which demand shall be accompanied by a statement setting forth the basis
for the calculations of the amount being claimed, a copy of which shall be

                                      -34-
<PAGE>
 
furnished to the Agent), the Company will indemnify such Lender against any net
loss or expense which such Lender may sustain or incur (including, without
limitation, any net loss or expense incurred by reason of the liquidation or
reemployment of deposits or other funds acquired by such Lender to fund or
maintain any Eurodollar Loan), as reasonably determined by such Lender, as a
result of (a) any payment or prepayment or conversion of any Eurodollar Loan of
such Lender on a date other than the last day of an Interest Period for such
Loan (including, without limita  tion, any conversion pursuant to Section 8.3)
                                                                  ----------- 
or (b) any failure of the Company to borrow or convert any Loans on a date
specified therefor in a notice of borrowing or conversion pursuant to this
Agreement (other than as a result of a default by such Lender or the Agent).
For this purpose, all notices to the Agent pursuant to this Agreement shall be
deemed to be irrevocable.

          8.5  Right of Lenders to Fund through Other Offices.  Subject to
               ----------------------------------------------             
clause (a) of Section 8.7, each Lender may, if it so elects, fulfill its
              -----------                                               
commitment as to any Eurodollar Loan by causing a foreign branch or affiliate of
such Lender to make such Loan, provided that in such event for the purposes of
                               --------                                       
this Agreement such Loan shall be deemed to have been made by such Lender and
the obligation of the Company to repay such Loan shall nevertheless be to such
Lender and shall be deemed held by it, to the extent of such Loan, for the
account of such branch or affiliate.

          8.6  Discretion of Lenders as to Manner of Funding.  Notwithstanding
               ---------------------------------------------                  
any provision of this Agreement to the contrary, each Lender shall be entitled
to fund and maintain its funding of all or any part of its Loans in any manner
it sees fit, it being understood, however, that for the purposes of this
Agreement all determinations hereunder shall be made as if such Lender had
actually funded and maintained each Eurodollar Loan during each Interest Period
for such Loan through the purchase of deposits having a maturity corresponding
to such Interest Period and bearing an interest rate equal to the Eurodollar
Rate for such Interest Period.

          8.7  Mitigation of Circumstances; Replacement of Affected Lender.  (a)
               -----------------------------------------------------------      
Each Lender shall promptly notify the Company and the Agent of any event of
which it has knowledge which will result in, and will use reasonable commercial
efforts available to it (and not, in such Lender's sole

                                      -35-
<PAGE>
 
judgment, otherwise disadvantageous to such Lender) to mitigate or avoid, (i)
any obligation by the Company to pay any amount pursuant to Section 7.6 or 8.1
                                                            -----------    ---
(ii) the occur rence of any circumstance of the nature described in Section 8.2
                                                                    -----------
or 8.3 (and, if any Lender has given notice of any such event described in
   ---                                                                    
clause (i) or (ii) above and thereafter such event ceases to exist, such Lender
- ----------    ----                                                             
shall promptly so notify the Company and the Agent).  Without limiting the
foregoing, each Lender will designate a different funding office if such
designation will avoid (or reduce the cost to the Company of) any event
described in clause (i) or (ii) of the preceding sentence and such designation
             ----------    ----                                               
will not, in such Lender's sole judgment, be otherwise disadvantageous to such
Lender.

          (b) At any time any Lender is an Affected Lender, the Company may
replace such Affected Lender as a party to this Agreement with one or more other
bank(s) or financial institution(s) reasonably satisfactory to the Agent, such
bank(s) or financial institution(s) to have a Commitment or Commitments, as the
case may be, in such amounts as shall be reasonably satisfactory to the Agent
(and upon notice from the Company such Affected Lender shall assign, without
recourse or warranty, its Commitment, its Loans, its Note and all of its other
rights and obligations hereunder to such replacement bank(s) or other financial
institution(s) for a purchase price equal to the sum of the principal amount of
the Loans so assigned, all accrued and unpaid interest thereon, its ratable
share of all accrued and unpaid non-use fees, any amounts payable under Section
                                                                        -------
8.4 as a result of such Lender receiving payment of any Eurodollar Loan prior to
- ---                                                                             
the end of an Interest Period therefor and all other obligations owed to such
Affected Lender hereunder).

          8.8  Conclusiveness of Statements; Survival of Provisions.
               ----------------------------------------------------  
Determinations and statements of any Lender pursuant to Section 8.1, 8.2, 8.3 or
                                                        -----------  ---  ---

          SECTION 9  WARRANTIES.

          To induce the Agent and the Lenders to enter into this Agreement and
to induce the Lenders to make Loans hereunder, the Company warrants to the Agent
and the Lenders that:

          9.1  Organization, Power, etc.  Each of the Company and each of its

Subsidiaries (a) is a corporation or a partnership, as the case may be, validly
organized and existing and in good standing under the laws of the state of its
organization, and (b) is duly qualified to do business and is in good standing
as a foreign corporation or partnership, as the case may be, in each
jurisdiction where the nature of its activities or properties makes such
qualification necessary and where any failure so to qualify, individually or in
the aggregate for all such failures, would have a Materially Adverse Effect.
Each of the Company and each of its Subsidiaries has full power and authority to
own and hold under lease its property and to conduct its business as currently
conducted by it, other than governmental licenses, consents and approvals the
failure to hold which, individually or in the aggregate for all such failures,
would not have a Materially Adverse Effect.  The Company has full power and
authority to execute, deliver, and perform its obligations under this Agreement
and each Note and to borrow Loans hereunder.

          9.2  Authorization; No Conflict.  The execution and delivery of this

Agreement and each Note, the borrowings hereunder, and the performance by the
Company of its obligations under this Agreement and each Note are within the
Company's corporate powers, have all been duly authorized by all necessary
corporate action or other organizational action, have received all necessary

authority or agency or any judicial decision, decree or order of any court or
other governmental authority, and will not result in or require the creation or
imposition of any Lien on any properties, assets, or revenues of the Company or
any of its Subsidiaries pursuant to the provisions of any Contractual Obligation
of the Company or any of its Subsidiaries.

terminated) shall immediately terminate and the Notes and all other obligations
hereunder shall become immediately due and payable, all without presentment,
demand, protest or notice of any kind; and in the case of any other Event of
Default, the Agent may, and upon written request of the Required Lenders shall,
declare the Commitments (if they have not theretofore terminated) to be
terminated and/or declare all Notes and all other obligations hereunder to be
due and payable, whereupon the Commitments (if they have not theretofore
terminated) shall immediately terminate and/or all Notes and all other
obligations hereunder shall become immediately due and payable, all without

          SECTION 13  THE AGENT.

          13.1  Authorization.  Each Lender authorizes the Agent to act on
                -------------                                             
behalf of such Lender to the extent provided herein or any other document or
instrument delivered hereunder or in connection herewith, and to take such other
action as may be reasonably incidental thereto.

          13.2  Indemnification.  Each Lender agrees to reimburse and indemnify
                ---------------

accordance with such Lender's Percentage) of any loss, damage, penalty, action,
judgment, obligation, cost, disbursement, liability or expense (including
reasonable attorneys' fees) which may at any time be incurred by the Agent (and
for which the Agent is not reimbursed by the Company) arising out of or in

                                      -60-
<PAGE>
 
connection with the performance of its obligations or the exercise of its powers
hereunder or any other document or instrument delivered hereunder or in
connection herewith, as well as the costs and expenses of defending against any
claim against the Agent arising hereunder or thereunder, provided that no Lender
                                                         --------               
shall be liable for any of the foregoing which are determined by a court of
competent jurisdiction in a final proceeding to have resulted solely from the
Agent's gross negligence or willful misconduct.

          13.3  Exculpation.  The Agent shall be entitled to rely upon advice of
                -----------                                                     
counsel concerning legal matters, and upon this Agreement and any schedule,
certificate, statement, report, notice or other writing which it believes to be
genuine or to have been presented by a proper person. Neither the Agent nor any
of its directors, officers, employees or agents shall (i) be responsible for any
recitals, representations or warranties contained in, or for the execution,
validity, genuineness, effectiveness or enforceability of, this Agreement or any
other instrument or document delivered hereunder or in connection herewith, (ii)
be responsible for the validity, genuineness, perfection, effectiveness,
enforceability, existence, value or enforcement of any collateral security,
(iii) be under any duty to inquire into or pass upon any of the foregoing
matters, or to make any inquiry concerning the performance by the Company or any
other obligor of its obligations, or (iv) in any event, be liable as such for
any action taken or omitted by it or them, except for its or their own gross
negligence or willful misconduct.  The agency hereby created shall in no way
impair or affect any of the rights and powers of, or impose any duties or
obligations upon, the Agent in its individual capacity.

          13.4  Credit Investigation.  Each Lender acknowledges that it has made
                --------------------                                            
such inquiries and taken such care on its own behalf as would have been the case
had such Lender's Commitment been granted and such Lender's Loans been made
directly by such Lender to the Company without the intervention of the Agent or
any other Lender.  Each Lender agrees and acknowledges that the Agent makes no
representations or warranties about the creditworthiness of the Company or any
other party to this Agreement or with respect to the legality, validity,
sufficiency or enforceability of this Agreement or any Note or the value of any
security therefor.

          13.5  Agent and Affiliates.  The Agent in its individual capacity
                --------------------                                       
shall have the same rights and powers hereunder as any other Lender and may
exercise or refrain from exercising the same as though it were not the Agent,
and the Agent and its affiliates may accept deposits from and generally engage
in any kind of business with the Company or any affiliate thereof as if the
Agent were not the Agent hereunder.

          13.6  Action on Instructions of the Required Lenders.  As to any
                ----------------------------------------------            
matters not expressly provided for by this Agreement (including, without
limitation, enforcement of this Agreement and collection of the Loans), the
Agent shall not be required to exercise any discretion or take any action, but
the Agent shall in all cases be fully protected in acting or refraining from
acting upon the written instructions (i) from the Required Lenders, except for
instructions which under the express provisions hereof must be received by the
Agent from all Lenders, and (ii) in the case of such instructions, from all
Lenders.  In no event will the Agent be required to take any action which
exposes the Agent to personal liability or which is contrary to this Agreement
or applicable law.  The relationship between the Agent and the Lenders is and
shall be that of agent and principal only and nothing herein contained shall be
construed to constitute the Agent a trustee for any holder of a Note or of a
participation therein nor to impose on the Agent duties and obligations other
than those expressly provided for herein.

          13.7  Funding Reliance.  (a)  Unless the Agent receives notice from a
                ----------------                                               
Lender by 11:00 a.m., Chicago time, on the day of a proposed borrowing that such
Lender will not make available to the Agent the amount which would constitute
its Percentage of such borrowing in accordance with Section 2.3, the Agent may
                                                    -----------               
assume that such Lender has made such amount available to the Agent and, in
reliance upon such assumption, make a corresponding amount available to the
Company.  If and to the extent such Lender has not made any such amount
available to the Agent, such Lender and the Company jointly and severally agree
to repay such amount to the Agent forthwith on demand, together with interest
thereon (i) in the case of the Company, the interest rate applicable to Loans
comprising such borrowing and (ii) in the case of such Lender, the Federal Funds
Rate (or, beginning on the third Business Day after demand, the rate set forth
in clause (i)).  Nothing set forth in this clause
   ----------                              ------

                                      -62-

(a) shall relieve any Lender of any obligation it may have to make any Loan
- ---                                                                        
hereunder.

          (b)  Unless the Agent receives notice from the Company prior to the
due date for any payment hereunder that the Company does not intend to make such
payment, the Agent may assume that the Company has made such payment and, in
reliance upon such assumption, make available to each Lender its share of such
payment.  If and to the extent that the Company has not made any such payment to
the Agent, each Lender which received a share of such payment shall repay such
share (or the relevant portion thereof) to the Agent forthwith on demand,
together with interest thereon at the Federal Funds Rate (or, beginning on the
third Business Day after demand, at the Alternate Reference Rate).  Nothing set
forth in this clause (b) shall relieve the Company of any obligation it may have
              ----------                                                        
to make any payment hereunder.

          13.8  Resignation.  The Agent may resign as such at any time upon at
                -----------                                                   
least 30 days' prior notice to the Company and the Lenders.  In the event of any
such resignation, the Required Lenders (with, so long as no Event of Default or
Unmatured Event of Default exists, the consent of the Company, which consent
shall not be unreasonably delayed or withheld) shall as promptly as practicable
appoint a successor Agent.  If no successor shall have been so appointed, and
shall have accepted such appointment, within 30 days after the giving of notice
of such resignation, then the retiring Agent may, on behalf of the Lenders,
appoint a successor Agent, which shall be a commercial bank organized under the
laws of the United States of America having a combined capital, surplus and
undivided profits of at least $500,000,000.  Upon the acceptance of any
appointment as Agent hereunder by a successor Agent, such successor Agent shall
thereupon succeed to and become vested with all rights, powers, privileges and
duties of the retiring Agent, and the retiring Agent shall be discharged from
all further duties and obligations under this Agreement.  After any resignation
pursuant to this Section 13.8, the provisions of this Section 13 shall inure to
                 ------------                         ----------               
the benefit of the retiring Agent as to any actions taken or omitted to be taken
by it while it was Agent hereunder.

or withheld), at any time assign and delegate to one or more commercial banks or
other Persons (any Person to whom such an assignment and delegation is to be
made being herein called an "Assignee"), all or any fraction of such Lender's
Loans and Commitment (which assignment and delegation shall be of a constant,
and not a varying, percentage of all the assigning Lender's Loans) in a minimum
aggregate amount equal to the lesser of (i) the assigning Lender's remaining
Commitment and (ii) $5,000,000; provided, however, that (a) no assignment and
                                --------  -------                            
delegation may be made to any Person if, at the time of such assignment and
delegation, the Company would be obligated to pay any greater amount under
Section 7.6 or Section 8 to the Assignee than the Company is then obligated to

date when all of the following conditions hall have been met:

               (x)  five Business Days (or such lesser period of time as the
     Agent and the assigning Lender shall agree) shall have passed after written
     notice of such assignment and delegation, together with payment
     instructions, addresses and related information with respect to such
     Assignee,

                                      -67-
<PAGE>
 
     shall have been given to the Company and the Agent by such assigning Lender
     and the Assignee,

               (y)  the assigning Lender and the Assignee shall have executed
     and delivered to the Company and the Agent an assignment agreement
     substantially in the form of Exhibit D (an "Assignment Agreement"),
                                  ---------                             
     together with any documents required to be delivered thereunder, which
     Assignment Agreement shall have been accepted by the Agent and the Company,
     and

               (z)  the assigning Lender or the Assignee shall have paid the
     Agent a processing fee of $2,500.

From and after the date on which the conditions described above have been met,
(x) such Assignee shall be deemed automatically to have become a party hereto
and, to the extent that rights and obligations hereunder have been assigned and
delegated to such Assignee pursuant to such Assignment Agreement, shall have the
rights and obligations of a Lender hereunder, and (y) the assigning Lender, to
the extent that rights and obligations hereunder have been assigned and
delegated by it pursuant to such Assignment Agreement, shall be released from
its obligations hereunder. Within five Business Days after effectiveness of any
assignment and delegation, the Company shall execute and deliver to the Agent
(for delivery to the Assignee and the Assignor, as applicable) a new Note in the
principal amount of the Assignee's Commitment and, if the assigning Lender has
retained a Commitment hereunder, a replacement Note in the principal amount of
the Commitment retained by the assigning Lender (such Note to be in exchange
for, but not in payment of, the predecessor Note held by such assigning Lender).
Each such Note shall be dated the effective date of such assignment.  The
assigning Lender shall mark the predecessor Note "exchanged" and deliver it to
the Company. Accrued interest on that part of the predecessor Note being
assigned shall be paid as provided in the Assignment Agreement.  Accrued
interest and fees on that part of the predecessor Note not being assigned shall
be paid to the assigning Lender.  Accrued interest and accrued fees shall be
paid at the same time or times provided in the predecessor Note and in this
Agreement.  Any attempted assignment and delegation not made in accordance with
this Section 14.9.1 shall be null and void.

          Notwithstanding the foregoing provisions of this Section 14.9.1 or any
                                                           --------------       
other provision of this Agreement, any Lender may at any time assign all or any
portion of its Loans and its Note to a Federal Reserve Bank (but no such
assignment shall release any Lender from any of its obligations hereunder).

          14.9.2  Participations.  Any Lender may at any time sell to one or
                  --------------                                            
more commercial banks or other Persons participating interests in any Loan owing
to such Lender, the Note held by such Lender, the Commitment of such Lender or
any other interest of such Lender hereunder (any Person purchasing any such
participating interest being herein called a "Participant").  In the event of a
sale by a Lender of a participating interest to a Participant, (x) such Lender
shall remain the holder of its Note for all purposes of this Agreement and (y)
the Company and the Agent shall continue to deal solely and directly with such
Lender in connection with such Lender's rights and obligations hereunder.  No
Participant shall have any direct or indirect voting rights hereunder (except
that a Lender may grant a Participant rights with respect to any of the events
described in the penultimate sentence of Section 14.1).  The Company agrees that
                                         ------------                           
if amounts outstanding under this Agreement and the Notes are due and payable
(as a result of acceleration or otherwise), each Participant shall be deemed to
have the right of setoff in respect of its participating interest in amounts
owing under this Agreement and any Note to the same extent as if the amount of
its participating interest were owing directly to it as a Lender under this
Agreement or such Note; provided that such right of setoff shall be subject to
                        --------                                              
the obligation of each Participant to share with the Lenders, and the Lenders
agree to share with each Participant, as provided in Section 7.5.  The Company
                                                     -----------              
also agrees that each Participant shall be entitled to the benefits of Section
                                                                       -------
7.6 and Section 8 as if it were a Lender (provided that no Participant shall
- ---     ---------                                                           
receive any greater compensation pursuant to such Sections than would have been
paid to the participating Lender if no participation had been sold).

          14.10  Governing Law.  This Agreement and each Note shall be a
                 -------------                                          
contract made under and governed by the laws of the State of Illinois applicable
to contracts made and to be performed entirely within the State of Illinois.
Whenever possible each provision of this Agreement shall be interpreted in such
manner as to be effective and valid

                                      -69-

under applicable law, but if any provision of this Agreement shall be prohibited
by or invalid under applicable law, such provision shall be ineffective to the
extent of such prohibition or invalidity, without invalidating the remainder of
such provision or the remaining provisions of this Agreement.  All obligations
of the Company and rights of the Agent and the Lenders expressed herein or in
the Notes shall be in addition to and not in limitation of those provided by
applicable law.

          14.11  Counterparts.  This Agreement may be executed in any number of
                 ------------                                                  
counterparts and by the different parties hereto on separate counterparts and
each such counterpart shall together constitute but one and the same Agreement.
When counterparts executed by all of the parties hereto shall have been lodged
with the Agent (or, in the case of any Lender as to which an executed
counterpart shall not have been so lodged, the Agent shall have received
confirmation from such Lender of execution of a counterpart hereof by such
Lender), this Agreement shall become effective as of the date hereof, and at
such time the Agent shall notify the Company and each Lender.

            -----                                                               
$1.00 per share, of the Company, including the associated Rights (as defined in
Section 6.1(b)) (together, the "Shares") at a price of $22.00 per Share in cash,
                                ------                                          
net to the seller, subject to the terms and conditions set forth in Annex A
hereto (the "Offer Conditions").  The initial expiration date of the Offer shall

be the date twenty business days from and including the date (the "Commencement
                                                                   ------------
Date") the Offer Documents (as hereinafter defined) are first filed with the
- ----

                                         ---                             
expressly reserve the right, in their sole discretion, to waive any condition
(other than the Minimum Condition, as defined in the Offer Conditions) and to
set forth or change any other term and condition of the Offer, provided that,
                                                               --------      
unless previously approved by the Company in writing, no provision may be set
forth or changed which decreases the price per Share payable in the Offer,
changes the form of consideration payable in the Offer (other than by adding
consideration), reduces the maximum number of Shares to be purchased in the
Offer, or imposes conditions to the Offer
<PAGE>
 
in addition to those set forth herein that are materially adverse to holders of
the Shares. Merger Sub covenants and agrees that, subject to the terms and
conditions of the Offer, including but not limited to the Offer Conditions, it
will accept for payment and pay for Shares as soon as it is permitted to do so
under applicable law, provided that Merger Sub shall have the right, in its sole
                      --------                                                  
discretion, to extend the Offer from time to time notwithstanding the prior
satisfaction of the Offer Conditions.  It is agreed that the terms and
conditions set forth in the Offer, including but not limited to the Offer
Conditions, are for the benefit of Purchaser and Merger Sub and may be asserted
by Purchaser and Merger Sub regardless of the circumstances giving rise to any
such condition.

          (b)  The Company hereby approves of and consents to the Offer and
represents and warrants that:  (i) its Board of Directors, at a meeting duly
called and held on March 2, 1998, has unanimously (A) determined that this
Agreement and the transactions contemplated hereby, including each of the Offer
and the Merger (as defined in Section 2.1), are fair to and in the best
interests of the holders of Shares, (B) approved this Agreement and the
transactions contemplated hereby, including each of the Offer and the Merger,
and (C) resolved to recommend that the stockholders of the Company accept the
Offer, tender their Shares to Merger Sub thereunder and approve this Agreement
and the transactions contem  plated hereby; and (ii) Credit Suisse First Boston
(the "Financial Advisor") has delivered to the Board of Directors of the Company
      -----------------                                                         
its written opinion that the consideration to be received by holders of Shares,
other than Purchaser and Merger Sub, pursuant to each of the Offer and the
Merger is fair to such holders from a financial point of view. The Company has
been authorized by the Financial Advisor to permit, subject to prior review and
consent by such Financial Advisor (such consent not to be unreasonably
withheld), the inclusion of such fairness opinion (or a reference thereto) in a
Solicitation/Recommendation Statement on Schedule 14D-9 (the "Schedule 14D-9")
                                                              --------------  
to be filed with the SEC upon commencement of the Offer and in the Proxy
Statement referred to in Section 7.3(a).  The Company hereby consents to the
inclusion in the Offer Documents (as defined in Section 1.1(c)) of the
recommendations of the Board of Directors of the Company described herein.

          (c)  Purchaser agrees, as to the Offer to Purchase and related Letter
of Transmittal (which together constitute the "Offer Documents"), and the
                                               ---------------           
Company agrees, as to the Schedule 14D-9, that such documents shall, in all
material respects, comply with the requirements of the Securities Exchange Act
of 1934, as amended, and the rules and regulations thereunder (the "Exchange
                                                                    --------
Act") and other applicable laws.  The Company and its counsel, as to the Offer
Documents, and Purchaser and its counsel, as to the Schedule 14D-9, shall be
given an opportunity to review such documents a reasonable time prior to their
being filed with the SEC.  Purchaser, Merger Sub and the Company each agrees
promptly to correct any information provided by it for use in the Offer
Documents or the Schedule 14D-9, as applicable, that shall have become false or
misleading in any material respect, and Purchaser and  Merger Sub, on the one
hand, and the Company, on the other hand, further agree to take all steps
necessary to cause the Offer Documents and the Schedule

                                      -2-
<PAGE>
 
14D-9, as the case may be, as so corrected to be filed with the SEC and
disseminated to holders of Shares, in each case as and to the extent required by
applicable federal securities laws.

          (d)  In connection with the Offer, the Company will cause its transfer
agent to furnish promptly to Merger Sub a list, as of a recent date, of the
record holders of Shares and their addresses, as well as mailing labels
containing the names and addresses of all record holders of Shares and lists of
security positions of Shares held in stock depositories. The Company will
furnish Merger Sub with such additional information (including, but not limited
to, updated lists of holders of Shares and their addresses, mailing labels and
lists of security positions) and such other assistance as Purchaser or Merger
Sub or their agents may reasonably request in communicating the Offer to the
record and beneficial holders of Shares.

Merger has been duly filed with the Secretary of State of Delaware, and such
time is hereinafter referred to as the "Effective Time."

Effective Time shall be the Certificate of Incorporation of the Surviving
Corporation, until duly amended in accordance with the terms thereof and the
DGCL, except that Article Fourth of the Company Certificate shall be amended

                                   ARTICLE IV

                             OFFICERS AND DIRECTORS
                          OF THE SURVIVING CORPORATION

          4.1.  Officers and Directors.  The directors of Merger Sub and the
                ----------------------                                      
officers of the Company at the Effective Time shall, from and after the
Effective Time, be the directors and officers, respectively, of the Surviving
Corporation until their successors have been duly elected or appointed and
qualified or until their earlier death, resignation or removal in accordance
with the Surviving Corporation's Certificate of Incorporation and By-Laws.

          4.2.  Boards of Directors; Committees.  If requested by Purchaser, the
                -------------------------------                                 
Company will, subject to compliance with applicable law and promptly following
the purchase by Merger Sub of Shares pursuant to the Offer, take all actions
necessary to cause persons designated by Purchaser to become directors of the
Company so that the total number of such persons equals not less than the
product of (i) the total number of directors on the Board of Directors of the
Company (giving effect to the directors elected pursuant to this sentence) and
(ii) a fraction the numerator of which is the aggregate number of Shares
beneficially owned by Merger Sub or any affiliate of Merger Sub and the
denominator of which is the total number of Shares then outstanding.  In
furtherance thereof, the Company will increase the size of the Board of
Directors of the Company, or use its reasonable efforts

                                      -4-
<PAGE>
 
to secure the resignation of directors, or both, as is necessary to permit
Purchaser's designees to be elected to the Board of Directors of the Company.
At such time, the Company, if so requested, will use its reasonable efforts to
cause persons designated by Purchaser to constitute the same proportionate
representation of each committee of the Board of Directors of the Company, each
board of directors of each subsidiary of the Company and each committee of each
such board (in each case to the extent of the Company's ability to elect such
persons).  No directors appointed by Purchaser shall be entitled to receive any
compensation or benefits currently in effect for the Company's non-employee
directors.  The Company's obligations to appoint designees to the Board of
Directors of the Company shall be subject to Section 14(f) of the Exchange Act
and Rule 14f-1 promulgated thereunder. The Company shall promptly take all
actions required pursuant to such Section and Rule in order to fulfill its
obligations under this Section 4.2 and shall include in the Schedule 14D-9, or
in a separate Rule 14f-1 information statement provided to stockholders,  such
information with respect to the Company and its officers and directors as is
required under Section 14(f) and Rule 14f-1 to fulfill its obligations under
this Section 4.2.  Purchaser and Merger Sub will supply to the Company and will
be solely responsible for any information with respect to either of them and
their nominees, officers, directors and affiliates required by Section 14(f) and
Rule 14f-1.

          4.3  Actions by Directors.  For purposes of Article IX and Sections
               --------------------                                          
10.3 and 10.4, no action taken by the Board of Directors of the Company after
the date of the consummation of the Offer and prior to the Merger shall be
effective unless such action is approved by the affirmative vote of at least a
majority of the directors of the Company which are not officers of Purchaser or
designees, stockholders or affiliates of Purchaser.

              CONVERSION OR CANCELLATION OF SHARES IN THE MERGER

          5.1.  Conversion or Cancellation of Shares.  The manner of converting
                ------------------------------------                           
or canceling shares of the Company and Merger Sub in the Merger shall be as
follows:

          (a)  At the Effective Time, each Share of the Company issued and
outstanding immediately prior to the Effective Time (other than Shares owned by
Purchaser, Merger Sub or any other subsidiary of Purchaser (collectively, the
"Purchaser Companies") or Shares that are held by stockholders ("Dissenting
- --------------------                                             ----------
Stockholders") exercising appraisal rights pursuant to Section 262 of the DGCL)
- ------------                                                                   
shall, by virtue of the Merger and without any action on the part of the holder
thereof, be converted into the right to receive, without interest, an amount in
cash (the "Merger Consideration") equal to $22.00 or such greater amount which
           --------------------                                               
may be paid pursuant to the Offer.  All Shares (other than those owned by the
Purchaser Companies), by virtue of the Merger and without any action on the part
of the holders thereof, shall no longer be outstanding and shall be canceled and
retired and shall cease to exist, and each

                                      -5-
<PAGE>
 
holder of a certificate representing any such Shares shall thereafter cease to
have any rights with respect to such Shares, except the right to receive the
Merger Consideration for such Shares upon the surrender of such certificate in
accordance with Section 5.2 or the right, if any, to receive payment from the
Surviving Corporation of the "fair value" of such Shares as determined in
accordance with Section 262 of the DGCL.

          (b)  At the Effective Time, each Share issued and outstanding at the
Effective Time and owned by any of the Purchaser Companies, and each Share
issued and held in the Company's treasury at the Effective Time, shall, by
virtue of the Merger and without any action on the part of the holder thereof,
cease to be outstanding, shall be canceled and retired without payment of any
consideration therefor and shall cease to exist.

          (c)  At the Effective Time, each share of Common Stock, par value
$0.001 per share, of Merger Sub issued and outstanding immediately prior to the
Effective Time shall, by virtue of the Merger and without any action on the part
of Merger Sub or the holders of such shares, be converted into one Share.

          5.2.  Payment for Shares.  Purchaser shall make available or cause to
                ------------------                                             
be made available to the paying agent appointed by Purchaser with the Company's
prior approval (the "Paying Agent") amounts sufficient in the aggregate to
                     ------------                                         
provide all funds necessary for the Paying Agent to make payments pursuant to
Section 5.1(a) hereof to holders of Shares issued and outstanding immediately
prior to the Effective Time (other than Shares owned by the Purchaser
Companies).  Such funds shall be invested by the Paying Agent as directed by
Purchaser, provided that such investments shall be in obligations of or
           --------                                                    
guaranteed by the United States of America, in commercial paper obligations
rated A-1 or P-1 or better by Moody's Investors Service, Inc. or Standard &
Poor's Corporation, respectively, or in certificates of deposit, bank repurchase
agreements or banker's acceptances of commercial banks with capital exceeding
$500 million. Any net profit resulting from, or interest or income produced by,
such investments will be payable to the Surviving Corporation or Purchaser, as
Purchaser directs.  Promptly after the Effective Time, the Surviving Corporation
shall cause to be mailed to each person who was, at the Effective Time, a holder
of record (other than any of the Purchaser Companies) of Shares a form (mutually
agreed to by Purchaser and the Company) of letter of transmittal and
instructions for use in effecting the surrender of the certificates which,
immediately prior to the Effective Time, represented any of such Shares in
exchange for payment therefor.  Upon surrender to the Paying Agent of such
certificates, together with such letter of transmittal, duly executed and
completed in accordance with the instructions thereto, the Surviving Corporation
shall promptly cause to be paid to the persons entitled thereto a check in the
amount to which such persons are entitled as Merger Consideration, after giving
effect to any required tax withholdings.  No interest will be paid or will
accrue on the amount payable upon the surrender of any such certificate.  If
payment is to be made to a person other than the registered holder of the
certificate surrendered, it shall be a condition of such payment that the
certificate so

                                      -6-
<PAGE>
 
surrendered shall be properly endorsed or otherwise in proper form for transfer
and that the person requesting such payment shall pay any transfer or other
taxes required by reason of the payment to a person other than the registered
holder of the certificate surrendered or establish to the satisfaction of the
Surviving Corporation or the Paying Agent that such tax has been paid or is not
applicable.  One hundred and eighty days following the Effective Time, the
Surviving Corporation shall be entitled to cause the Paying Agent to deliver to
it any funds (including any interest received with respect thereto) made
available to the Paying Agent which have not been disbursed to holders of
certificates formerly representing Shares outstanding on the Effective Time, and
thereafter such holders shall be entitled to look to the Surviving Corporation
only as general creditors thereof with respect to the cash payable upon due
surrender of their certificates.  Notwithstanding the foregoing, neither the
Paying Agent nor any party hereto shall be liable to any holder of certificates
formerly representing Shares for any amount paid to a public official pursuant
to any applicable abandoned property, escheat or similar law.  The Surviving
Corporation shall pay all charges and expenses, including those of the Paying
Agent, in connection with the exchange of cash for Shares and Purchaser shall
reimburse the Surviving Corporation for such charges and expenses.

          5.3.  Dissenters' Rights.  If any Dissenting Stockholder shall be
                ------------------                                         
entitled to be paid the "fair value" of his or her Shares, as provided in
Section 262 of the DGCL, the Company shall give Purchaser notice thereof and
Purchaser shall have the right to participate in all negotiations and
proceedings with respect to any such demands.  Neither the Company nor the
Surviving Corporation shall, except with the prior written consent of Purchaser,
voluntarily make any payment with respect to, or settle or offer to settle, any
such demand for payment.  If any Dissenting Stockholder shall fail to perfect or
shall have effectively withdrawn or lost the right to dissent, the Shares held
by such Dissenting Stockholder shall thereupon be treated as though such Shares
had been converted into the Merger Consideration pursuant to Section 5.1.

          5.4.  Transfer of Shares After the Effective Time.  No transfers of
                -------------------------------------------                  
Shares shall be made on the stock transfer books of the Surviving Corporation at
or after the Effective Time.

hereby represents and warrants to Purchaser and Merger Sub that:

          (a)   Corporate Organization and Qualification. Each of the Company

and its subsidiaries is a corporation duly organized, validly existing and in
good standing under the

<PAGE>
 
laws of its respective jurisdiction of incorporation and is in good standing as
a foreign corporation in each jurisdiction where the properties owned, leased or
operated, or the business conducted, by it require such qualification, except
for such failure to so qualify or be in such good standing, which, when taken
together with all other such failures, is not reasonably likely to have a
material adverse effect on the financial condition, properties, business or

information statement required to be filed or otherwise filed with the SEC (the
"Company Reports") prepared by it since December 31, 1996 (the "Audit Date"),
 ---------------                                                ----------

applicable requirements under the Exchange Act and did not, and any Company
Reports filed with the SEC subsequent to the date hereof will not, contain any
untrue statement of a material fact or omit to state a material fact required to

the circumstances in which they were made, not misleading.  Each of the

incorporated by reference into the Company Reports (including the related notes
and schedules) fairly presents the consolidated financial position of the
Company and its subsidiaries as of its date and each of the consolidated
statements of earnings, stockholders' equity and cash flows included in or

subsidiaries for the periods set forth therein (subject, in the case of
unaudited statements, to normal year-end audit adjustments which will not be
material in amount or effect), in each case in accordance with generally

Reports filed with the SEC prior to the date hereof or otherwise disclosed in
the Disclosure Letter, since the Audit Date, the Company and its subsidiaries
have conducted their respective businesses only in, and have not engaged in
any material transaction other than according to, the ordinary and usual course
of such businesses and there has not been (i) any material adverse change in the
financial condition, properties, business or results of operations of the
Company and its subsidiaries taken as a whole or any development or combination
of developments of which management of the Company has knowledge that is
reasonably likely to result in any such change; (ii) any material change in the
net projected liability relating to asbestos or silica or projected insurance
recovery related thereto included in the Company Reports or any development or
combination of developments of which management of the Company has knowledge
that is reasonably likely to result in any such change; (iii) any declaration,
setting aside or payment of any dividend or other distribution with respect to
the capital stock of the Company; or (iv) any change by the Company in
accounting principles, practices or methods.  Since the Audit Date, except as

prior to the date hereof and other than in the ordinary course, there has not
been any increase in the compensation payable or which could become payable by
the Company and its subsidiaries to their officers or key employees, or any
amendment of any Benefit Plans (as defined in Section 7.1).

          (g)  Litigation and Liabilities.  Except as disclosed with reasonable

specificity in the Company Reports filed with the SEC prior to the date hereof

liabilities, whether or not accrued, contingent or otherwise, including, without
limitation, those relating to matters involving any Environmental Law (as
defined in Section 6.1(m)), or any other facts or circumstances of which the
management of the Company is aware that could result in any claims against or
obligations or liabilities of the Company or any of its subsidiaries, that,
alone or in the aggregate, are reasonably likely to

                                      -11-
<PAGE>
 
have a material adverse effect on the financial condition, properties, business
or results of operations of the Company and its subsidiaries taken as a whole.

claims, obligations and liabilities relating to asbestos and silica, including,
without limitation, product and general liability.

Income Security Act of 1974, as amended ("ERISA") are listed in the Disclosure
                                          -----                               
Letter and any "change of control" or similar provisions therein are
specifically identified in the Disclosure Letter.  True and complete copies of
all Compensation and Benefit Plans and such other benefit plans, contracts or
arrangements, including, but not limited to, any trust instruments and insurance
contracts, if any, forming a part of any such plans and agreements, and all
amendments thereto have been made available to Purchaser.

          (ii)  All Compensation and Benefit Plans are in substantial compliance
with applicable law and all Compensation and Benefit Plans which are employee
benefit plans, other than "multiemployer plans" within the meaning of Sections
3(37) of ERISA, covering employees (the "Plans") to the extent subject to ERISA,
are in substantial compliance with ERISA.  Each Plan which is an "employee
pension benefit plan" within the meaning of Section 3(2) of ERISA ("Pension
                                                                    -------
Plan") and which is intended to be qualified under Section 401(a) of the
Internal Revenue Code of 1986, as amended (the "Code"), has received a favorable
                                                ----                            
determination letter from the Internal Revenue Service with respect to "TRA" (as
defined in Section 1 of Internal Revenue Service Revenue Procedure 93-39), and
the Company is not aware of any circumstances likely to result in revocation of
any such favorable determination letter.  There is no material pending or, to
the knowledge of the Company, threatened litigation relating to the Compensation
and Benefit Plans.  Neither the Company nor any subsidiary has engaged in a
transaction with respect to any Plan that, assuming the taxable period of such
transaction expired as of the date hereof, could subject the Company or any of
its subsidiaries to a material tax or penalty imposed by either Section 4975 of
the Code or Section 502(i) of ERISA.

          (iii)  No liability under Subtitle C or D of Title IV of ERISA has
been or is expected to be incurred by the Company or any subsidiary with respect
to any ongoing, frozen or terminated "single-employer plan", within the meaning
of Section 4001(a)(15) of ERISA, currently or formerly maintained by any of
them, or the single-employer plan of any

                                      -12-
<PAGE>
 
entity which is considered one employer with the Company under Section 4001 of
ERISA or Section 414 of the Code (an "ERISA Affiliate").  The Company and its
                                      ---------------                        
subsidiaries have not incurred and do not expect to incur any withdrawal
liability with respect to a multiemployer plan under Subtitle E of Title IV of
ERISA.  No notice of a "reportable event", within the meaning of Section 4043 of
ERISA for which the 30-day reporting requirement has not been waived, has been
required to be filed for any Pension Plan or by any ERISA Affiliate within the
12-month period ending on the date hereof.

          (iv)  All contributions required to be made under the terms of any
Plan have been timely made.  Neither any Pension Plan nor any single-employer
plan of an ERISA Affiliate has an "accumulated funding deficiency" (whether or
not waived) within the meaning of Section 412 of the Code or Section 302 of
ERISA.  Neither the Company nor its subsidiaries has provided, or is required to
provide, security to any Pension Plan or to any single-employer plan of an ERISA
Affiliate pursuant to Section 401(a)(29) of the Code.

          (v)  Except as set forth in the Disclosure Letter, under each Pension
Plan which is a single-employer plan, as of the last day of the most recent plan
year ended prior to the date hereof, the actuarially determined present value of
all "benefit liabilities", within the meaning of Section 4001(a)(16) of ERISA
(as determined on the basis of the actuarial assumptions contained in the Plan's
most recent actuarial valuation), did not exceed the then current value of the
assets of such Plan, and there has been no material change in the financial
condition of such Plan since the last day of the most recent Plan Year.  The
withdrawal liability of the Company and its subsidiaries under each Benefit Plan
which is a multiemployer plan to which the Company, its subsidiaries or an ERISA
Affiliate has contributed during the preceding 12 months, determined as if a
"complete withdrawal", within the meaning of Section 4203 of ERISA, had occurred
as of the date hereof, does not exceed $100,000.

          (vi)  Neither the Company nor the subsidiaries have any obligations
for retiree health and life benefits under any Plan, except as set forth in the
Disclosure Letter.  The Company or its subsidiaries may amend or terminate any
such Plan pursuant to the terms thereof.

          (vii)  Except as set forth in the Disclosure Letter, the consummation
of the transactions contemplated by this Agreement will not (x) entitle any
employees of the Company or any of its subsidiaries to severance pay, (y)
accelerate the time of payment or vesting or trigger any payment of compensation
or benefits under, increase the amount payable or trigger any other material
obligation pursuant to, any of the Compensation and Benefit Plans or (z) result
in any breach or violation of, or a default under any of the Compensation and
Benefit Plans.

                                      -13-
<PAGE>
 
          (viii)  All Compensation and Benefit Plans covering non-U.S. Employees
comply in all material respects with applicable local law.  Except as set forth
in the Disclosure Letter, the Company and its subsidiaries have no material
unfunded liabilities with respect to any Pension Plan which covers non-U.S.
Employees.

          (ix)  The method of allocating the portion of the proceeds of the
Offer from the suspense account which is part of the A.P. Green Industries, Inc.
Employee Stock Ownership Trust, which implements and forms part of the A.P.
Green Investment Plan (collectively, the "ESOP") to participants' accounts in
accordance with Section 7.8(d) hereof will not violate the terms of the ESOP.

          (i)  Compliance.  Neither the Company nor any of its subsidiaries is
               ----------

reasonably likely to have a material adverse effect on the financial condition,
properties, business or results of operations of the Company and its
subsidiaries taken as a whole, or could prevent, delay or materially burden the
transactions contemplated by this Agreement.

               ------------- 

          (i)  The transactions contemplated hereby have been approved by the
Board of Directors of the Company in accordance with Article Sixth of the
Company Certificate and, as a result thereof, Article Sixth is inapplicable to
the Offer and the Merger.

          (ii)  The Company has taken all necessary action under the Rights
Agreement to provide that the execution of this Agreement and the consummation
of the transactions contemplated hereby will not cause (i) Merger Sub and/or

Merger Sub is a corporation duly organized, validly existing and in good
standing under the laws of its respective jurisdiction of incorporation and is
in good standing as a foreign corporation in each jurisdiction where the
properties owned, leased or operated, or the business conducted, by it require
such qualification except for such failure to so qualify or to be in such good
standing, which, when taken together with all other such failures, is not
reasonably likely to have a material adverse effect on the financial condition,
properties, business or results of operations of Purchaser and its subsidiaries,
taken as a whole.  Each of Purchaser and its subsidiaries has the requisite
corporate power and authority to carry on its respective businesses as they are
now being conducted.

approvals, permits or authorizations required to be obtained by Purchaser and
Merger Sub from, any Governmental Entity in connection with the execution and
delivery of this Agreement by Purchaser and Merger Sub and the consummation by
Purchaser and Merger Sub of the transactions contemplated hereby, the failure to
make or obtain any or all of which could prevent, delay or materially burden the
transactions contemplated by this Agreement.

          (ii)  The execution and delivery of this Agreement by Purchaser and
Merger Sub do not, and the consummation by Purchaser and Merger Sub of the
transactions contemplated by this Agreement will not, constitute or result in
(i) a breach or violation of, or a default under, the Certificate of
Incorporation or By-Laws of Purchaser or Merger Sub or the comparable governing
instruments of any of their subsidiaries or (ii) a breach or violation of, a
default under, the acceleration of or the creation of a lien, pledge, security
interest or other encumbrance on assets (with or without the giving of notice or
the lapse of time) pursuant to, any provision of any Contract of Purchaser or
Merger Sub or any of their subsidiaries or any law, ordinance, rule or
regulation or judgment, decree, order, award or governmental or non-governmental
permit or license to which Purchaser or Merger Sub or any of their subsidiaries
are subject, except, in the case of clause (ii) above, for such breaches,
violations, defaults or accelerations or changes that, alone or in the
aggregate, could not prevent or delay or materially burden the transactions
contemplated by this Agreement.

               -----

          7.2.  Acquisition Proposals.  The Company, its affiliates and its and
                ---------------------                                          
their respective officers, directors, employees, representatives and agents
(including, without limitation, any investment banker, attorney or accountant
retained by the Company or any of its subsidiaries) shall immediately cease all
existing discussions or negotiations, if any, with any parties conducted
heretofore with respect to any acquisition or exchange of all or any material
portion of the assets of, or more than 15% of the equity interest in, the
Company or any of its subsidiaries (by direct purchase from the Company, tender
or exchange offer or otherwise) or any business combination, merger,
consolidation or similar transaction (including an exchange of stock or assets)
with or involving the Company or any subsidiary or division of the Company (an
"Acquisition Transaction").  Neither the Company nor any of its affiliates, nor
- ------------------------

or indirectly, encourage, solicit, participate in or initiate discussions or
negotiations with, or provide any information to, any corporation, partnership,
person or other entity or group (other than Purchaser and Merger Sub, any
affiliate or associate of Purchaser and Merger Sub or any

                                      -20-
<PAGE>
 
designees of Purchaser and Merger Sub) with respect to any inquiries or the
making of any offer or proposal (including, without limitation, any offer or
proposal to the stockholders of the Company) concerning an Acquisition
Transaction (an "Acquisition Proposal"), unless (i) the Board of Directors of
                 --------------------                                        
the Company determines in good faith after consultation with outside legal
counsel that such action is necessary in order for its directors to comply with
their respective fiduciary duties under applicable law and (ii) the Board of
Directors of the Company determines in good faith (after consultation with its
financial advisor) that such Acquisition Proposal, if accepted, is reasonably
likely to be consummated (taking into account all legal, financial and
regulatory aspects of the proposal, the person making the proposal and all other
relevant factors) and would, if consummated, result in a transaction more
favorable to the Company's stockholders from a financial point of view than the
transaction contemplated by this Agreement (any such more favorable Acquisition
Proposal being referred to in this Agreement as a "Superior Proposal").  The
                                                   -----------------        
Company will take the necessary steps to inform the individuals or entities
referred to in the first sentence hereof of the obligations undertaken in this
Section 7.2.  The Company will notify Purchaser immediately if any such
inquiries or proposals are received by, any such information is requested from,
or any such negotiations or discussions are sought to be initiated or continued
with the Company, the name of the person making such proposals (unless
identifying such person is prohibited by a binding confidentiality agreement in
effect as of February 25, 1998), the material terms and conditions of such
proposals and thereafter shall keep Purchaser informed, on a current basis, of
the status and terms of such proposals and the status of such negotiations or
discussions.  The Company agrees not to release any third party from, or waive
any provisions of, any confidentiality or standstill agreement to which the
Company is a party, unless the Board of Directors of the Company shall have
determined in good faith, based upon the advice of outside counsel to the
Company, that failing to release such third party or waive such provisions would
constitute a breach of the fiduciary duties of the Board of Directors of the
Company under applicable law.

          7.3.  Meetings of the Company's Stockholders.  (a) If required
                --------------------------------------                  
following termination of the Offer, the Company will take, consistent with
applicable law, the Company Certificate and the Company By-Laws, all action
necessary to convene a meeting of holders of Shares as promptly as practicable
following the purchase of Shares pursuant to the Offer to consider and vote upon
the approval of this Agreement and the Merger.  Subject to fiduciary
requirements of applicable law, the Board of Directors of the Company shall
recommend such approval and the Company shall take all lawful action to solicit
such approval.  At any such meeting of the Company all of the Shares then owned
by the Purchaser Companies will be voted in favor of this Agreement.  The
Company's proxy or information statement with respect to such meeting of
shareholders (the "Proxy Statement"), at the date thereof and at the date of
                   ---------------                                          
such meeting, will comply in all material respects with the applicable
requirements under the Exchange Act and will not include an untrue statement of
a material fact or omit to state a material fact required to be stated therein
or necessary to make the statements therein, in light of the circumstances under
which they were made, not

                                      -21-
<PAGE>
 
misleading; provided, however, that the foregoing shall not apply to the extent
            --------  -------                                                  
that any such untrue statement of a material fact or omission to state a
material fact was made by the Company in reliance upon and in conformity with
written information concerning the Purchaser Companies furnished to the Company
by Purchaser specifically for use in the Proxy Statement.  The Proxy Statement
shall not be filed, and no amendment or supplement to the Proxy Statement will
be made by the Company, without consultation with Purchaser and its counsel.

          (b)  Notwithstanding the foregoing, in the event that Merger Sub shall
acquire at least 90% of the outstanding Shares, the Company agrees, at the
request of  Merger Sub, subject to Article VIII, to take all necessary and
appropriate action to cause the Merger to become effective as soon as reasonably
practicable after such acquisition, without a meeting of the Company's
stockholders, in accordance with Section 253 of the DGCL.

          7.4.  Filings; Other Action.  (a) Subject to the terms and conditions
                ---------------------

other action and do, or cause to be done, all other things necessary, proper or
appropriate under applicable laws and regulations to consummate and make
effective the transactions contemplated by this Agreement, including but not
limited to cooperating in the preparation and filing of the Offer Documents, the
Schedule 14D-9, the Proxy Statement, any required filings under the HSR Act or
other foreign filings and any amendments to any thereof.  The Company shall use
all reasonable efforts to obtain all licenses, permits, consents, approvals,
authorizations, qualifications and orders of governmental authorities and
parties to Contracts with the Company and its subsidiaries as are necessary for
the consummation of the transactions contemplated by this Agreement and to
fulfill the conditions to the Offer and the Merger. The Company will cooperate
with Purchaser and Merger Sub with respect to consummating the financing for the
Offer and the Merger and any refinancing of the Company's indebtedness.
Notwithstanding anything contained herein to the contrary, Purchaser shall be
under no obligation whatsoever to make or accept or engage in negotiations for
any settlement with any governmental entity or any other arrangement involving
the sale, disposition, or separate holding, through the establishment of a
trust, or otherwise, of the business or any of the assets of the Company or any
of its subsidiaries acquired pursuant to this Agreement, or any portion thereof,
or particular assets of Purchaser or its subsidiaries or any of the Purchaser
Companies in order to complete the transactions contemplated herein.

          (b)  The Company and Purchaser each shall keep the other apprised of
the status of matters relating to completion of the transactions contemplated
hereby, including promptly furnishing the other with copies of notices or other
communications received by Purchaser or the Company, as the case may be, or any
of their subsidiaries, from any

or any other antitrust law.

                ------                                                 
subsidiaries to) afford Purchaser's officers, employees, counsel, lenders,
accountants and other authorized representatives ("Representatives") access,

properties, books, Contracts and records and, during such period, the Company
shall (and shall cause each of its subsidiaries to) furnish promptly to
Purchaser all information concerning its business, properties and personnel as

                                                         --------        
investigation pursuant to this Section 7.5 shall affect or be deemed to modify
any representation or warranty made by the Company and provided, further, that
                                                       --------  -------      
the foregoing shall not require the Company to permit any inspection, or to
disclose any information, which in the reasonable judgment of the Company would
result in the disclosure of any trade secrets of third parties or violate any
obligation of the Company with respect to confidentiality if the Company shall
have used reasonable efforts to obtain the consent of such third party to such
inspection or disclosure. All requests for information made pursuant to this
Section shall be directed to an executive officer of the Company or such person
as may be designated by any such officer.  Upon any termination of this
Agreement, Purchaser will collect and deliver to the Company all documents
obtained by it or any of its Representatives then in their possession and any
copies thereof.

          7.6.  Notification of Certain Matters.  The Company shall give prompt
                -------------------------------                                
notice to Purchaser of:  (a) any notice of, or other communication relating to,
any environmental matter, a default or event that, with notice or lapse of time
or both, would become a default, received by the Company or any of its
subsidiaries subsequent to the date of this Agreement and prior to the Effective
Time, under any Contract to which the Company or any of its subsidiaries is a
party or is subject; (b) any changes or developments relating to any Action
pending or, to the knowledge of management of the Company, threatened against
the Company or any of its subsidiaries existing as of the date hereof; (c) any
new Actions pending or, to the knowledge of management of the Company,
threatened against the Company or any of its subsidiaries since the date hereof;
(d) any material adverse change in the financial condition or results of
operations of the Company and its subsidiaries taken as a whole as compared to
the financial condition and results of operations of the Company and its
subsidiaries disclosed in the consolidated financial statements of the Company
as of and for the year ended December 31, 1997 which are set forth in the
Disclosure Letter or the occurrence of any event which, so far as reasonably can
be foreseen at the time of its

                                      -23-
<PAGE>
 
occurrence, is reasonably likely to result in any such change; and (e) any
material adverse change in the properties or  business of the Company and its
subsidiaries taken as a whole or the occurrence of any event which, so far as
reasonably can be foreseen at the time of its occurrence, is reasonably likely
to result in any such change.  Each of the Company and Purchaser shall give
prompt notice to the other party of any notice or other communication from any
third party alleging that the consent of such third party is or may be required
in connection with the transactions contemplated by this Agreement.

          7.7.  Publicity.  The initial press release relating to the execution
                ---------                                                      
of this Agreement shall be a joint press release and thereafter the Company and
Purchaser, unless they have previously agreed in writing to the contrary, will
not issue any press release or otherwise make a public statement with respect to
the transactions contemplated hereby or make any filings with any Governmental
Entity or with any national securities exchange with respect thereto, unless in
the written opinion of counsel to the party desiring to make such disclosure, a
copy of which opinion shall be delivered to the other party as promptly as
practicable under the circumstances, such disclosure is required by law or stock
exchange rule or regulation.

          7.8.  Stock Options and Employee Benefits.
                ----------------------------------- 

          (a)   Stock Options - Cash Exchange.  Subject to Section 7.8(b),
                -----------------------------                             
immediately prior to the Effective Time, the Company shall take such actions as
may be necessary such that immediately prior to the Effective Time each stock
option outstanding and unexercised pursuant to the Stock Plans (the "Option"),
                                                                     ------   
whether or not then exercisable, shall be canceled and shall cease to be
exercisable.  In consideration for such cancellation, the holder thereof, as
soon as practicable after the Effective Time, will receive an amount in cash
from Purchaser equal to the result of multiplying the number of shares of
Company Common Stock previously subject to such Option by the difference between
the Merger Consideration and the per share exercise price of such Option.

          (b)   Stock Options - Option Exchange.  (i)  The executives of the
                -------------------------------                             
Company that are listed in Exhibit 7.8(b) may, by written notice to Purchaser
received by Purchaser not less than ten (10) business days prior to the
Effective Time, elect to convert the Options held by them, up to the number of
Options so designated in Exhibit 7.8(b), into options ("Purchaser Options") to
                                                        -----------------     
purchase Purchaser common stock ("Purchaser Common Stock"). Any such election
                                  ----------------------                     
shall identify the Options to be converted into Purchaser Options and shall
become irrevocable upon receipt by Purchaser of the notice of election.  If such
election is made, at the Effective Time, each Option to be converted shall be
deemed to constitute an option to acquire Purchaser Common Stock on the same
terms of the applicable Stock Plan and the stock option agreement by which it is
evidenced.  From and after the Effective Time, (A) each such Option may be
exercised solely for shares of Purchaser Common Stock, (B) the number of shares
of Purchaser Common Stock subject to such Option shall be equal

                                      -24-
<PAGE>
 
to the result (rounded down to the nearest whole share) of multiplying the
number of shares of Company Common Stock subject to such Option immediately
prior to the Effective Time by a fraction (the "Conversion Fraction"), where (x)
                                                -------------------             
the numerator is equal to the Merger Consideration and (y) the denominator is
equal to the average of the last reported sales prices of the Purchaser Common
Stock on the five business days immediately prior to the date hereof and (C) the
per share exercise price under each such Option shall be equal to the result
(rounded up to the nearest cent) of dividing the per share exercise price under
each such Option by the Conversion Fraction; provided, however, that with
                                             --------  -------           
respect to any Option which is an "incentive stock option", within the meaning
of Section 422 of the Code, the adjustments provided by this Section 7.8(b)(i)
shall be effected in a manner consistent with the requirements of Section 424(a)
of the Code.  No payment shall be made pursuant to Section 7.8(a) with respect
to any portion of an Option that is converted into a Purchaser Option as
aforesaid.

                (ii)  (A) At or prior to the Effective Time, Purchaser shall
take all corporate action necessary to reserve for issuance a sufficient number
of shares of Purchaser Common Stock for delivery upon exercise of Options
assumed by it in accordance with Section 7.8(b)(i) and (B) as soon as
administratively feasible following the Effective Time, file a registration
statement on Form S-8 (or any successor or other appropriate form) with respect
to the Purchaser Common Stock subject to such Options (or shall cause such
Option to be deemed an option issued pursuant to a Purchaser stock option plan
for which Purchaser Common Stock have previously been registered pursuant to an
appropriate registration form). Purchaser shall use its best efforts to maintain
the effectiveness of such registration statement (and maintain the current
status of the prospectus or prospectuses contained therein) for so long as the
Options remain outstanding.

          (c)  Employee Benefits.  Purchaser agrees that during the period
               -----------------                                          
commencing at the Effective Time and ending on the first anniversary thereof,
the employees of the Company will continue to be provided with benefits under
employee benefit plans (other than stock options or other plans involving the
potential issuance of securities of the Company or Purchaser) which in the
aggregate are substantially comparable to those currently provided by the
Company to such employees; provided, however, that employees covered by
                           --------  -------                           
collective bargaining agreements need not be provided with such benefits.
Purchaser will cause each employee benefit plan of Purchaser in which employees
of the Company are eligible to participate to take into account for purposes of
eligibility and vesting thereunder the service of such employees with the
Company as if such service were with Purchaser.  Purchaser will, and will cause
the Surviving Corporation to, honor without modification all employee benefit
obligations to current and former employees of the Company accrued as of the
Effective Time and, to the extent set forth in the Disclosure Letter, all
employee severance plans in existence on the date hereof and all employment or
severance agreements adopted by the Board of Directors of the Company and
entered into prior to the date hereof.

                                      -25-

     (d)  ESOP Distributions and Termination.  As soon as practicable following
          ----------------------------------                                   
the Effective Time, Purchaser and the Company shall take all actions necessary
or appropriate to cause the A.P. Green Industries, Inc. Employee Stock Ownership
Trust, which implements and forms part of the A.P. Green Investment Plan
(collectively, the "ESOP"), to provide for the use of all proceeds received
pursuant to the Offer from the tender of Shares allocated to the suspense
account of the ESOP, as follows:  first, such proceeds shall be applied to repay
any outstanding loan incurred by the ESOP; and secondly, the balance of such
proceeds shall be allocated to participants' Employer Match ESOP account in
proportion to the total aggregate value of such accounts of the participants as
of the accounting date immediately preceding the Effective Time, except to the
extent such allocations could exceed the limits on annual contributions pursuant
to Section 415 of the Code.  In addition, as soon as is reasonably practicable
following the Effective Time (or, if deemed appropriate by Purchaser and the
Company, after receipt of a favorable determination letter from the Internal
Revenue Service on the effect of termination of the ESOP) Purchaser and the
Company shall terminate the ESOP and distribute all proceeds to the participants
in accordance therewith. Notwithstanding the foregoing, Purchaser shall have no
obligation to implement this Section 7.8(d) if such implementation would violate
the terms of the ESOP or jeopardize the tax-qualified status of the ESOP.

          7.9.  Indemnification; Directors' and Officers' Insurance.  (a) From
                ---------------------------------------------------           
and after the Effective Time, Purchaser agrees that it will cause the Surviving
Corporation to indemnify and hold harmless each present and former director and
officer of the Company, determined as of the Effective Time (the "Indemnified
                                                                  -----------
Parties"), against any costs or expenses (including reasonable attorneys' fees),
- -------                                                                         
judgments, fines, losses, claims, damages or liabilities (collectively, "Costs")
                                                                         -----  
incurred in connection with any Action, whether civil, criminal, administrative
or investigative, arising out of matters existing or occurring at or prior to
the Effective Time, whether asserted or claimed prior to, at or after the
Effective Time, to the fullest extent that the Company is permitted to do so
under Delaware law and the Company Certificate or Company By-Laws in effect on
the date hereof (and Purchaser shall also advance expenses as incurred to the
fullest extent permitted under applicable law provided the person to whom
expenses are advanced provides an undertaking to repay such advances if it is
ultimately determined that such person is not entitled to indemnification);
provided that any determination required to be made with respect to whether an
- --------                                                                      
officer's or director's conduct complies with the standards set forth under
Delaware law and the Company Certificate and Company By-Laws shall be made by
independent counsel selected by the Surviving Corporation.

          (b)  Any Indemnified Party wishing to claim indemnification under
paragraph (a) of this Section 7.9, upon learning of any such Action, shall
promptly notify Purchaser thereof.  In the event of any such Action (whether
arising before or after the Effective Time), (i) Purchaser or the Surviving
Corporation shall have the right to assume the defense thereof and Purchaser
shall not be liable to such Indemnified Parties for any legal expenses of other

                                      -26-
<PAGE>
 
counsel or any other expenses subsequently incurred by such Indemnified Parties
in connection with the defense thereof, except that if Purchaser or the
Surviving Corporation elects not to assume such defense or counsel for the
Indemnified Parties advises that, in such counsel's reasonable judgment, there
are material issues that constitute conflicts of interest between Purchaser or
the Surviving Corporation and the Indemnified Parties, the Indemnified Parties
may retain counsel satisfactory to them, and Purchaser or the Surviving
Corporation shall pay all reasonable fees and expenses of such counsel for the
Indemnified Parties promptly as statements therefor are received; provided,
                                                                  -------- 
however, that Purchaser shall be obligated pursuant to this paragraph (b) to pay

for only one firm of counsel for all Indemnified Parties in any jurisdiction,
(ii) the Indemnified Parties will cooperate in the defense of any such matter
and (iii) Purchaser shall not be liable for any settlement effected without its
prior written consent; and provided, further, however, that Purchaser shall not
                           --------  -------  -------                          
have any obligation hereunder to any Indemnified Party when and if a court of
competent jurisdiction shall ultimately determine, and such determination shall
have become final, that the indemnification of such Indemnified Party in the
manner contemplated hereby is pro  hibited by applicable law.

          (c)  The Surviving Corporation shall be permitted to maintain the
Company's existing officers' and directors' liability insurance ("D&O
                                                                  ---
Insurance") for a period of two years after the Effective Time so long as the
annual premium therefor is not in excess of 150% of the last annual premium paid
prior to the date hereof (the "D&O Premium"); provided, however, if the existing
                               -----------    --------  -------                 
D&O Insurance expires, is terminated or canceled during such two year period,
the Surviving Corporation will use its best efforts to obtain as much D&O
Insurance as can be obtained for the remainder of such period for a premium not
in excess (on an annualized basis) of the D&O Premium.

          7.10.  Environmental Filings.  The Company shall promptly make all
                 ---------------------

Environmental Laws including without limitation those relating to the ownership,

with copies of all Environmental Submissions at the time of filing and Purchaser
shall cooperate with the Company in the preparation and execution of all
Environmental Submissions.

          7.11.  Other Actions by the Company.
                 ---------------------------- 

          (a)  Takeover Statutes. If any Takeover Statute shall become
               -----------------                                      
applicable to the transactions contemplated hereby, the Company and the members
of the Board of Directors of the Company shall grant such approvals and take
such actions as are necessary so that the transactions contemplated hereby may
be consummated as promptly as practicable on the terms contemplated hereby and
otherwise act to eliminate or minimize the effects of such

Directors of the Company shall amend the Rights Agreement so that the
consummation of the transactions contemplated hereby will not cause (x) Merger
Sub and/or Purchaser to become an Acquiring Person (as defined in the Rights
Agreement) or (y) a Distribution Date or a Stock Acquisition Date (as such terms
are defined in the Rights Agreement) to occur, irrespective of the number of
Shares acquired pursuant to the Offer. In addition, the Board of Directors of
the Company shall either (i) amend the Rights Agreement prior to the
commencement of the Offer so that all outstanding Rights will expire upon the
acceptance of Shares for payment pursuant to the Offer, whether or not tendered
and purchased pursuant to the Offer, and neither the Company, Merger Sub nor
Purchaser shall have any obligations under the Rights or the Rights Agreement to
any holder (or former holder) of Rights following consummation of the Offer or
(ii) redeem all of the outstanding Rights immediately prior to the consummation
of the Offer so that the Company, Merger Sub and Purchaser shall have no
obligations under the Rights or the Rights Agreement following such time and the
holders shall have no rights under the Rights or the Rights Agreement following
such time, other than the redemption payment of $0.001 per Right as provided in
the Rights Agreement.

          9.4.  Termination by the Company.  This Agreement may be terminated
                --------------------------                                   
and the transactions contemplated hereby may be abandoned at any time prior to

current version of such agreement (which shall include all of the material
terms, including the price proposed to be paid for Shares pursuant thereto) to

the Company's written notification of its intention to enter into a binding
agreement for a Superior Proposal, an offer that the Board of Directors of the
Company determines, in good faith after consultation with its financial
advisors, is at least as favorable, from a financial point of view, to the
stockholders of the Company as the Superior Proposal and (z) the Company, prior
to such termination, pays to Purchaser in immediately available funds the fees
required to be paid pursuant to Section 9.5(b).

          9.5.  Effect of Termination and Abandonment.  (a) In the event of the
                -------------------------------------                          
termination of this Agreement pursuant to this Article IX, no party hereto (or
any of its directors or officers) shall have any liability or further obligation
to any other party to this Agreement, except as provided in Section 9.5(b) below
and Section 10.2 and except that nothing herein will relieve any party from
liability for any willful breach of this Agreement; provided, however, that if
                                                    --------  -------         
this Agreement is terminated by Purchaser pursuant to Section 9.3(i) or the
Company pursuant to Section 9.4(i), the terminating party's rights to pursue all
legal remedies will survive such termination unimpaired.

          (b) If (i) (x) the Offer shall have remained open for a minimum of at
least 20 business days, (y) after the date hereof any corporation, partnership,
person, other entity or group (as defined in Section 13(d)(3) of the Exchange
Act) other than Purchaser or Merger Sub or any of their respective subsidiaries
or affiliates (collectively, a "Person") shall have become the beneficial owner
                                ------                                         
of 20% or more of the outstanding Shares or shall have publicly

                                      -31-
<PAGE>
 
announced a proposal or intention to make an Acquisition Proposal or any Person
shall have commenced, or shall have publicly announced an intention to commence,
a tender offer or exchange offer for 20% or more of the outstanding Shares, and
(z) the Minimum Condition (as defined in Annex A) shall not have been satisfied
and the Offer is terminated without the purchase of any Shares thereunder, or
(ii) Purchaser shall have terminated this Agreement pursuant to Section 9.3(ii)
or Section 9.3(iii) or (iii) the Company shall have terminated this Agreement
pursuant to Section 9.4(ii), then the Company shall promptly, but in no event
later than two days after the date of such termination, pay Purchaser a fee of
$8,000,000 and shall reimburse Purchaser and Merger Sub (not later than one
business day after request by Purchaser or Merger Sub) for all of the out-of-
pocket charges and expenses, including financing fees, incurred by Purchaser or
Merger Sub in connection with this Agreement and the transactions contemplated
by this Agreement up to a maximum amount of $1,500,000, in each case payable by
wire transfer in same day funds.  The Company acknowledges that the agreements
contained in this Section 9.5(b) are an integral part of the transactions
contemplated in this Agreement, and that, without these agreements, Purchaser
and Merger Sub would not enter into this Agreement; accordingly, if the Company
fails to promptly pay the amount due pursuant to this Section 9.5(b), and, in
order to obtain such payment, Purchaser or Merger Sub commences a suit which
results in a judgment against the Company for the fee set forth in this
paragraph (b), the Company shall pay to Purchaser or Merger Sub its costs and
expenses (including attorneys' fees) in connection with such suit, together with
interest on the amount of the fee at the prime rate of Bank of America National
Trust and Savings Association on the date such payment was required to be made.
The payments made by the Company pursuant to this Section 9.5(b) are the sole
and exclusive remedy of Purchaser and Merger Sub for any claim that Purchaser or
Merger Sub may have arising from or relating to the events set forth in Section
9.5(b)(i), (ii) or (iii).

A.P. Green Industries, Inc.
Green Boulevard
Mexico, Missouri  65265

Attention:    Mr. Paul F. Hummer, Chairman, President
              and Chief Executive Officer

Gentlemen:

In connection with the consideration by A.P. Green Industries, Inc. ("Green")
and Global Industrial Technologies, Inc. ("Global") of a possible business
combination transaction (a "Transaction") between Green and Global involving
Green and the refractories business of Global conducted by Harbison-Walker
Refractories Company ("H-W"), a wholly owned subsidiary of Global, Global is
prepared to make available to Green, and it is our understanding that Green is
prepared to make available to Global, certain information concerning the
business, financial condition, operations, assets and liabilities of H-W and
Green, respectively (herein collectively referred to, and further defined below,
as the "Evaluation Material"). The purpose of this letter agreement is to set
forth the understanding of Global and Green (the "Parties") with respect to the
conditions upon which Evaluation Material will be furnished by each to the
other, including their agreement to treat any Evaluation Material (whether
prepared by the Parties, their advisors or otherwise and irrespective of the
form of communication) which has been or will be furnished by or on behalf of
the Parties after the date hereof in accordance with the provisions of this
letter agreement, and to take or abstain from taking certain other actions
hereinafter set forth.

The term "Evaluation Material" shall be deemed to include all data, reports,
interpretations, forecasts and records, financial or otherwise, reflecting
information and concerning Green and H-W which is not available to the general
public and which the Parties, their affiliates or any of their respective
directors, partners, officers, employees, agents or advisors (including without
limitation, attorneys, accountants, consultants, bankers and financial advisors)
(collectively, "Representatives") provide to each other as well as all notes,
analyses, compilations, studies, interpretations or other documents prepared by
the Parties or their Representatives which contain, reflect or are based upon,
in whole or in part, the information furnished to the Parties or their
Representatives pursuant hereto.  The term "Evaluation Material" does not
include information which (1) is or becomes generally available to the public
other than as a result of a disclosure by a Party or its Representatives in
violation hereof, (2) was within the possession of a Party or its
Representatives prior to its being furnished to such Party by the other Party or
any Representative of the other Party pursuant hereto, provided that the source
of such information was not known by the Party claiming 
<PAGE>
 
such information is not Evaluation Material to be bound by a confidentiality
agreement with or other direct or indirect contractual, legal or fiduciary
obligation of confidentiality to the other Party or its Representatives with
respect to such information, or (3) becomes available to the Party to which such
information was furnished under this letter agreement on a non-confidential
basis from a sourse other than the other Party or any Representative of the
other Party, provided that such source is not known by the Party claiming such
information is not Evaluation Material to be bound to the other Party or its
Representatives by a confidentiality agreement or other direct or indirect
contractual, legal or fiduciary obligation with respect to such information, or
(4) is demonstrated, to the reasonable satisfaction of the Party that furnished
such information, to have been developed by the other Party or its
Representatives independently from the Evaluation Material.

The Parties hereby agree that, for a period of three years after the date
hereof, they and their Representatives shall use the Evaluation Material solely
for the purpose of evaluating a possible Transaction, the Evaluation Material
will be kept confidential, and they and their Representatives will not disclose
any of the Evaluation Material to any person in any manner whatsoever; provided,
however, that (1) either Party may make any disclosure of such information to
which the other Party gives its prior written consent and (2) any of such
information may be disclosed to those Representatives of a Party who need to
know such information for the sole purpose of evaluating a possible Transaction,
who agree to keep such information confidential, and who agree to be bound by
the terms hereof to the same extent as if they were parties hereto.
Notwithstanding the foregoing, unless and until the Parties reach an agreement
in principle regarding a Transaction, and subject to the following paragraph and
the first full paragraph on page 3, the Parties agree that (1) the Evaluation
Material, (2) the fact that Evaluation Material has been furnished hereunder,
and (3) the fact that discussions are taking place and may take place in the
future between the Parties and their Representatives regarding a Transaction,
will only be disclosed by the Parties or their Representatives to those
corporate officers and other corporate employees of the Parties, and, in the
case of Global, also to those corporate officers and other corporate employees
of H-W, to whom such disclosure is necessary in order for the Parties to
initially evaluate a Transaction and discuss terms for an agreement in
principle.  The Parties shall instruct such officers and employees to make no
further disclosure thereof and shall inform them of restrictions imposed by
applicable laws upon the disclosure and use of Evaluation Material. In any
event, each Party shall be responsible for the breach of this letter agreement
by any of its Representatives and agrees, at its sole expense, to take all
reasonable measures (including but not limited to court proceedings) to restrain
its Representatives from prohibited or unauthorized disclosure or use of the
Evaluation Material.
<PAGE>
 
In addition, unless they have previously agreed in writing to the contrary, the
Parties and their Representatives will not disclose to any other person (1) that
they have furnished Evaluation Material to each other, (2) that discussions or
negotiations have taken place or will take place concerning a possible
Transaction, or (3) any of the terms, conditions or other facts with respect
thereto (including the status thereof), unless in the written opinion of counsel
to the Party desiring to make such disclosure, a copy of which opinion shall be
delivered to the other Party, such disclosure is required by law or stock
exchange rule or regulation and then only with as much prior written notice to
the other Party as is practicable under the circumstances.  The term "person" as
used in this letter agreement shall be broadly interpreted to include the media
and any individual, corporation, partnership, group, or other entity.

Until the discussions contemplated by this letter agreement have been
terminated, Green, on the one hand, and Global, on the other, shall not make any
contract with any directors, officers, employees, advisors, customers,
suppliers, lenders or subcontractors of the other Party (other than in the
ordinary course of business) without the express written consent of such other
Party.  Each Party shall, as soon as possible after the date hereof, designate
one or more persons to whom contact may be made.  All communications regarding
the proposed Transaction, requests for additional information, and discussions
or questions regarding procedures, will be submitted or directed only to those
the person so designated for such purpose.

In the event that a Party or its Representatives are requested or required (by
deposition, interrogatories, requests for information or documents in legal
proceedings, subpoena, civil investigative demand or other similar process) to
disclose any of the Evaluation Material, that Party shall provide the other
Party with prompt written notice of any such request or requirement.  In such
event the other Party may seek a protective order or other appropriate remedy
and/or waive compliance with the provisions of this letter agreement.  If, in
the absence of a protective order or other remedy or the receipt of a waiver by
the other Party, the Party which has received such request or is subject to such
requirement and its Representatives are nonetheless, in the written opinion of
counsel to such Party, a copy of which opinion shall be delivered to the other
Party, legally compelled to disclose Evaluation Material to any tribunal or else
stand liable for contempt or suffer other censure or penalty, it or its
Representative may, without liability hereunder, disclose to such tribunal only
that portion of the Evaluation Material which it has been advised by such
counsel that it is legally required to disclose, provided that such Party, at
the expense of the other Party, exercises commercially reasonable efforts to
preserve the confidentiality of the Evaluation Material, including, without
limitation, by cooperating with the other Party to obtain an appropriate
protective order or other reliable assurance that confidential treatment will be
accorded the Evaluation Material by such tribunal.  Such efforts shall be at 
the expense of the other Party 
<PAGE>
 
if disclosure to such tribunal was not caused by or resulted from a previous
disclosure by the Party (or its Representatives) that received such request or
became subject to such requirement which was not permitted by this letter
agreement.

If either Party decides that it does not wish to participate in a Transaction,
it will promptly inform the other Party of that decision.  In that case, or at
any time upon the request of either Party for any reason or for no reason, each
Party will promptly deliver to the other Party all documents (and all copies
thereof) furnished to it or its Representatives by or on behalf of the other
Party pursuant hereto.  In the event of such a decision or request, all other
Evaluation Material prepared by the Parties or their Representatives shall be
immediately destroyed and no copy thereof shall be retained (except as may be
required by regulatory authorities to which you are subject).  Notwithstanding
the return or the destruction of the Evaluation Material, the Parties and their
Representatives will continue to be bound by their obligations of
confidentiality and other obligations hereunder for a period of three years
after the date hereof.

In consideration of the Evaluation Material being furnished, the Parties hereby
agree that, for a period of two years from the date hereof, neither of them
will, nor will any of their affiliates (including H-W), solicit to employ
officers or other employees of the other, or any of the other's affiliates
(including H-W), with whom it, its affiliates or its Representatives have had
contact, or who were specifically identified to it or its Representatives during
the period of its investigation of the Company, so long as they are employed by
the other Party or any of the other Party's affiliates (including H-W), without
obtaining the prior written consent of the other Party, provided that either
Party or its affiliates may make general solicitations of employment not
directed to the other Party, its affiliates or its employees.

The parties understand and acknowledge that the stock of Green and Global is
publicly-held. Green warrants to Global that it does not own, directly or
indirectly, any of the capital stock of Global nor does it own any option,
warrant or right to acquire any such stock.  Global warrants to Green that it
does not own, directly or indirectly, any of the capital stock of Green nor does
it own any option, warrant or right to acquire any such stock.  For a period of
eighteen (18) months from the date hereof, Green agrees that it will not,
directly or indirectly, by purchase or otherwise, through subsidiaries or
associates, acquire, offer to acquire, or agree to acquire ownership of or
warrants or options covering any common shares of Global without the prior
written approval of Global.  For a period of eighteen (18) months from the date
hereof, Global agrees that it will not, directly or indirectly, by purchase or
otherwise, through subsidiaries or associates, acquire, offer to acquire, or
agree to acquire ownership of or warrants or options covering any common shares
of Green without the prior written approval of Green.
<PAGE>
 
The Parties understand and acknowledge that no representation or warranty,
express or implied, is made or shall be deemed to have been made as to the
accuracy or completeness of any Evaluation Material furnished to them.  The
Parties agree that neither of them shall have any liability to the other or to
any Representatives of the other relating to or resulting from the use of
Evaluation Material except as may be set forth in a final definitive agreement.
Only those representations or warranties which are made in a final definitive
agreement regarding a Transaction, when, as and if executed and delivered by the
parties, and subject to such limitations and restrictions as may be specified
therein (the "definitive agreement"), will have any legal effect.  In
particular, but without prejudice to the generality of the foregoing, no
representation or warranty is given or shall be deemed to have been given as to
the achievement or reasonableness of any projections, management estimates,
prospects or returns contained in the Evaluation Material.  The Parties also
understand and acknowledge that the Evaluation Material does not purport to
contain all the information that may be required to evaluate a Transaction and
that they should conduct their own independent analysis of the Green and H-W, as
the case may be, and of the data contained in the Evaluation Material.
Furthermore, the Parties understand and acknowledge that the definitive
agreement will provide that neither of them have not relied on or been induced
to enter into such definitive agreement by any representation, warranty, promise
or assurance save as may be expressly set out in such definitive agreement and
subject to such limitations and restrictions as may be specified therein, and,
unless and to the extent provided to the contrary in a definitive agreement,
that any information provided to either of them that is subject to this letter
agreement which is inconsistent with any representation or warranty shall be
deemed an exception thereto.

The Parties agree that unless and until they have both executed and exchanged a
final definitive agreement providing for a Transaction, neither of them will be
under any legal obligation of any kind whatsoever with respect to a Transaction
or otherwise by virtue of this letter agreement, except the matters specifically
agreed to herein.  The Parties further acknowledge and agree that each of them
reserves the right, in its sole discretion, to reject any and all proposals made
by the other, or the other's affiliates or Representatives with regard to a
Transaction, and to terminate discussions and negotiations with the other at any
time for any reason or no reason.

It is understood and agreed that no failure or delay by either Party in
exercising any right, power or privilege hereunder shall operate as a waiver
thereof, nor shall any single or partial exercise thereof preclude any other or
further exercise thereof or the exercise of any other right, power or privilege
hereunder.
<PAGE>
 
It is understood and agreed that money damages would not be a sufficient remedy
for any breach of this letter agreement by either Party or any of its
Representatives and that each Party shall be entitled to equitable relief;
including injunction and specific performance, as a remedy for any such breach
and each Party hereby waives any requirement for the securing or posting of any
bond in connection with such remedy.  Such remedies shall not be deemed to be
the exclusive remedies for a breach of this letter agreement but shall be in
addition to all other remedies available at law or equity to the Parties and H-
W.

This letter agreement shall be governed by and construed in accordance with the
laws of the State of New York without regard to the conflicts of law provisions
thereof.

Please confirm the agreement of Green with the foregoing by signing and
returning one copy of this letter agreement to the undersigned, whereupon this
letter agreement shall become a binding agreement between you and the Company as
to the matters specifically agreed to herein.

                                     Very truly yours,
                        
                                     Global Industrial Technologies, Inc.



                                     J.L. Jackson, Chairman of the Board,
                                     President and Chief Executive Officer

Accepted and agreed as of
the date first above written
