To the Holders of Common Stock of
LeaRonal, Inc.:
 
                                 INTRODUCTION
 
  Lightning Acquisition Corp., a New York corporation ("Purchaser") and a
wholly owned subsidiary of Rohm and Haas Company, a Delaware corporation
("Parent"), hereby offers to purchase all outstanding shares of common stock,
par value $1.00 per share (the "Common Stock" or the "Shares"), of LeaRonal,
Inc., a New York corporation (the "Company"), at a price of $34.00 per Share,
net to the seller in cash, without interest (the "Offer Price"), upon the
terms and subject to the conditions set forth in this Offer to Purchase and in
the related Letter of Transmittal (which, as amended or supplemented from time
to time, collectively constitute the "Offer").
 
  Tendering stockholders of record who tender Shares directly will not be
obligated to pay brokerage fees or commissions or, except as set forth in
Instruction 6 of the Letter of Transmittal, stock transfer taxes on the
purchase of Shares by Purchaser pursuant to the Offer. However, any tendering
stockholder or other payee who fails to complete and sign the Substitute Form
W-9 included in the Letter of Transmittal may be subject to backup federal
income tax withholding of 31% of the gross proceeds payable to such
stockholder or other payee pursuant to the Offer. See Section 3. Stockholders
who hold their Shares through a bank or broker should check with such
institution as to whether they charge any service fees. Purchaser will pay all
fees and expenses of Deutsche Bank Securities Inc. ("Deutsche Bank
Securities") which is acting as Dealer Manager (in such capacity, the "Dealer
Manager"), ChaseMellon Shareholder Services, L.L.C. which is acting as the
Depositary (in such capacity, the "Depositary") and D.F. King & Co., Inc.,
which is acting as the Information Agent (in such capacity, the "Information
Agent"), incurred in connection with the Offer and in accordance with the
terms of the agreements entered into between Purchaser and/or Parent and each
such person. See Section 17.
 
  THE BOARD OF DIRECTORS OF THE COMPANY (THE "COMPANY BOARD") HAS UNANIMOUSLY
APPROVED THE MERGER AGREEMENT AND THE TRANSACTIONS CONTEMPLATED THEREBY,
INCLUDING THE OFFER AND THE MERGER (AS DEFINED BELOW), AND DETERMINED THAT THE
OFFER AND THE MERGER ARE FAIR TO, AND IN THE BEST INTERESTS OF, THE COMPANY'S
STOCKHOLDERS AND RECOMMENDS THAT STOCKHOLDERS ACCEPT THE OFFER AND TENDER
THEIR SHARES PURSUANT TO THE OFFER.
 
  THE BEACON GROUP CAPITAL SERVICES LLC ("BEACON"), FINANCIAL ADVISOR TO THE
COMPANY, HAS DELIVERED TO THE COMPANY BOARD ITS WRITTEN OPINION, DATED
DECEMBER 20, 1998 (THE "FINANCIAL ADVISOR OPINION"), TO THE EFFECT THAT, AS OF
SUCH DATE, THE CONSIDERATION TO BE RECEIVED BY THE HOLDERS OF SHARES PURSUANT
TO THE OFFER AND THE MERGER IS FAIR, FROM A FINANCIAL POINT OF VIEW, TO SUCH
HOLDERS OF SHARES. A COPY OF THE FINANCIAL ADVISOR OPINION IS ATTACHED AS AN
EXHIBIT TO THE COMPANY'S SOLICITATION/RECOMMENDATION STATEMENT ON SCHEDULE
14D-9 (THE "SCHEDULE 14D-9"), WHICH HAS BEEN FILED BY THE COMPANY WITH THE
SECURITIES AND EXCHANGE COMMISSION (THE "COMMISSION") IN CONNECTION WITH THE
OFFER AND WHICH IS BEING MAILED TO HOLDERS OF SHARES HEREWITH. HOLDERS OF
SHARES ARE URGED TO, AND SHOULD, READ THE FINANCIAL ADVISOR OPINION CAREFULLY.
 
  THE OFFER IS CONDITIONED UPON, AMONG OTHER THINGS, (I) THERE BEING VALIDLY
TENDERED AND NOT WITHDRAWN PRIOR TO THE EXPIRATION OF THE OFFER A NUMBER OF
SHARES REPRESENTING AT LEAST TWO-THIRDS OF THE FULLY DILUTED SHARES (THE
"MINIMUM CONDITION") AND (II) ANY APPLICABLE WAITING PERIOD UNDER THE HART-
SCOTT-RODINO ANTITRUST IMPROVEMENTS ACT OF 1976, AS AMENDED (THE "HSR ACT"),
HAVING EXPIRED OR BEEN TERMINATED. THE OFFER IS ALSO SUBJECT TO THE OTHER
CONDITIONS SET FORTH IN THIS OFFER TO PURCHASE. SEE SECTIONS 1 AND 15.
 
                                       1
<PAGE>
 
  Purchaser reserves the right (subject to the terms of the Merger Agreement
and the applicable rules and regulations of the Commission) to waive or reduce
the Minimum Condition and to elect to purchase, pursuant to the Offer, fewer
than the minimum number of Shares necessary to satisfy the Minimum Condition;
provided that, without the prior written consent of the Company, Purchaser may
not waive the Minimum Condition or reduce the Minimum Condition except to the
extent set forth in Section 1. The Purchaser currently does not intend to
waive or reduce the Minimum Condition. In addition, Purchaser reserves the
right, subject only to the applicable rules and regulations of the Commission,
to waive each of the other conditions (other than the Minimum Condition) to
the obligations of Purchaser to consummate the Offer, the Merger and the other
transactions contemplated by the Merger Agreement and the Tender and Option
Agreement (as defined below) (the "Transactions").
 
  The Company has advised Parent and Purchaser that each member of the Company
Board and each of the Company's executive officers intends to tender all
Shares owned by such persons pursuant to the Offer. In addition,
simultaneously with the execution and delivery of the Merger Agreement, Parent
and Purchaser, on the one hand, and certain stockholders on the other hand
(the "Certain Stockholders"), entered into a Tender and Option Agreement dated
as of December 20, 1998 (the "Tender and Option Agreement"). The Tender and
Option Agreement relates to the 3,619,664 issued and outstanding Shares owned
by the Certain Stockholders, as well as 778,896 Shares subject to Options (as
defined below), of which 82,800 such Options are presently exercisable. The
issued and outstanding Shares subject to the Tender and Option Agreement
currently represent approximately 29% of the issued and outstanding Shares.
The issued and outstanding Shares and presently exercisable Options subject to
the Tender and Option Agreement together represent approximately 27% of the
Fully Diluted Shares. Pursuant to the Tender and Option Agreement, each
Certain Stockholder has agreed, among other things, to grant the Purchaser an
option to purchase the Shares subject thereto upon the occurrence of certain
"Trigger Events" (as defined below) and to tender in the Offer, and not to
withdraw therefrom, the Shares owned by such Certain Stockholders, as well as
any other Shares acquired prior to the expiration of the Offer including
pursuant to the exercise of Options. See Section 12.
 
  As used in this Offer to Purchase, "Fully Diluted Shares" means all
outstanding securities entitled generally to vote in the election of directors
of the Company on a fully diluted basis, after giving effect to the exercise
or conversion of all options (including the Options), warrants, rights and
securities exercisable or convertible into such voting securities; provided
that Parent may, at its option exercisable in its sole discretion, exclude
from the calculation of Fully Diluted Shares any Options which are not
exercisable at the time such calculation is made and which will not become
exercisable by their terms prior to April 30, 1999 (consisting of, according
to the Company, approximately 972,508 Shares in respect of such Options as of
December 20, 1998). Parent has currently not elected to exercise such option
but reserves the right to do so. The Company has represented and warranted to
Parent and Purchaser that, as of December 20, 1998, (i) the authorized capital
stock of the Company consists of 35,000,000 Shares, (ii) 12,544,682 Shares are
issued and outstanding, and (iii) 1,313,364 Shares are issuable pursuant to
the exercise of the Company's outstanding stock options ("Options"). The
Merger Agreement provides, among other things, that the Company will not,
without the prior written consent of Parent, issue any shares of capital stock
of any class of the Company, or any options, warrants, convertible securities
or other rights of any kind to acquire any shares of such capital stock of the
Company (except for the issuance of Shares issuable pursuant to Options
outstanding on the date hereof). See Section 12. Based on the foregoing and
assuming that there are an aggregate of 13,858,046 Fully Diluted Shares, the
Minimum Condition will be satisfied if 9,238,698 Shares are validly tendered
and not withdrawn prior to the Expiration Date. See Section 3 under "--
Options."
 
 
                                       2

  The Offer is being made pursuant to an Agreement and Plan of Merger, dated
as of December 20, 1998 (the "Merger Agreement"), by and among Parent,
Purchaser and the Company. Pursuant to the Merger Agreement and in accordance
with the New York Business Corporation Law (the "NYBCL"), as promptly as
practicable after the completion of the Offer and satisfaction or waiver, if
permissible, of all conditions, including the purchase of Shares pursuant to
the Offer (sometimes referred to herein as the "consummation" of the Offer)
and the approval and adoption of the Merger Agreement by the stockholders of
the Company (if required by applicable law), Purchaser will be merged with and
into the Company (the "Merger") and the Company will be the surviving
corporation in the Merger (the "Surviving Corporation") and a wholly owned
subsidiary of Parent. At the effective time of the Merger (the "Effective
Time"), each Share then outstanding, other than Shares held by (i) the Company
or any of its subsidiaries, (ii) Parent or any of its subsidiaries, including
Purchaser and (iii) stockholders who properly perfect their dissenters' rights
under the NYBCL, if applicable, will be converted into the right to receive
$34.00 in cash (the "Merger Consideration"), without interest. The Merger
Agreement is more fully described in Section 12.
 
  The Merger Agreement provides that immediately upon the purchase by
Purchaser of Shares pursuant to the Offer, Purchaser shall be entitled to
designate such number of directors, rounded up to the next whole number, on
the Company Board as shall give Purchaser representation on the Company Board
equal to the product of the total number of directors on the Company Board
(giving effect to the directors elected pursuant to this sentence) multiplied
by the percentage that the number of votes represented by Shares beneficially
owned by Purchaser and its affiliates (including Shares so accepted for
payment and purchased) bears to the number of votes represented by Shares then
outstanding, and the Company shall, at such time, use its best efforts
promptly to cause Purchaser's designees to be elected as directors of the
Company, including increasing the size of the Company Board or securing the
resignations of incumbent directors or both.
 
  Consummation of the Merger is conditioned upon, among other things, the
approval and adoption by the requisite vote of stockholders of the Company of
the Merger Agreement and the Merger, if required by applicable law and the
Company's Certificate of Incorporation (the "Certificate of Incorporation").
See Section 12. Under the NYBCL and the Certificate of Incorporation, the
affirmative vote of the holders of two-thirds of the outstanding Shares is the
only vote of any class or series of the Company's capital stock that would be
necessary to approve the Merger Agreement and the Merger at a meeting of the
Company's stockholders. If the Minimum Condition is satisfied and Purchaser
purchases at least two-thirds of the outstanding Shares in the Offer,
Purchaser will be able to effect the Merger without the affirmative vote of
any other stockholder. Pursuant to the Merger Agreement, Parent and Purchaser
have agreed to vote the Shares acquired by them pursuant to the Offer in favor
of the Merger. See Section 13. In the event Purchaser reduces the Minimum
Condition as described in Section 1 and purchases less than two-thirds of the
Fully Diluted Shares, the Company shall convene a meeting of its shareholders
to amend the Certificate of Incorporation to provide that the requisite vote
of the Company's shareholders on any merger or consolidation (including the
Merger) shall be a majority of the Shares outstanding. Parent and Purchaser
have agreed to vote any Shares owned by them in favor with such amendment at
any such meeting. The Merger Agreement is more fully described in Section 12.
 
  Under Section 905 of the NYBCL, if a corporation owns at least 90% of the
outstanding shares of each class of a subsidiary corporation, the corporation
holding such stock may merge such subsidiary into itself, or itself into such
subsidiary, without any action or vote on the part of the board of directors
or the stockholders of such other corporation (a "short-form merger"). In the
event that Purchaser acquires in the aggregate at least 90% of the outstanding
Shares pursuant to the Offer or otherwise, Parent and Purchaser could effect a
short-form merger without any further approval of the Company Board or the
stockholders of the Company. Parent
 
                                       3
<PAGE>
 
and Purchaser presently intend to effect a short-form merger, if permitted to
do so under the NYBCL, pursuant to which Purchaser will be merged with and
into the Company. See Section 13.
 
  Certain Federal income tax consequences of the sale of Shares pursuant to
the Offer are described in Section 5.
 
  THIS OFFER TO PURCHASE AND THE RELATED LETTER OF TRANSMITTAL CONTAIN
IMPORTANT INFORMATION AND SHOULD BE READ CAREFULLY BEFORE ANY DECISION IS MADE
WITH RESPECT TO THE OFFER.
 
                                   THE OFFER
 
  1. TERMS OF THE OFFER. Upon the terms and subject to the conditions of the
Offer (including, if the Offer is extended or amended, the terms and
conditions of such extension or amendment), Purchaser will accept for payment
and pay for all Shares validly tendered prior to the Expiration Date, and not
properly withdrawn in accordance with Section 4. The term "Expiration Date"
shall mean 12:00 Midnight, New York City time, on Friday, January 22, 1999,
unless and until Purchaser, in accordance with the terms of the Merger
Agreement, shall have extended the period of time during which the Offer is
open, in which event the term "Expiration Date" shall mean the latest time and
date at which the Offer, as so extended by Purchaser, shall expire.
 
  The Offer is conditioned upon the satisfaction of the Minimum Condition, the
expiration or termination of any waiting period imposed by the HSR Act, and
the other conditions set forth in Section 15. If such conditions are not
satisfied at or prior to the Expiration Date, Purchaser reserves the right,
subject to the terms of the Merger Agreement and subject to complying with
applicable rules and regulations of the Commission, to (i) decline to purchase
any Shares tendered in the Offer and terminate the Offer and return all
tendered Shares to the tendering stockholders, (ii) waive any or all
conditions to the Offer (except the Minimum Condition; provided that Purchaser
may, in its sole discretion, reduce the Minimum Condition under certain
circumstances to not less than a majority of the Fully Diluted Shares as
described below) and, subject to complying with applicable rules and
regulations of the Commission, purchase all Shares validly tendered, (iii)
extend the Offer and, subject to the right of stockholders to withdraw Shares
until the Expiration Date, retain all Shares which have been tendered during
the period or periods for which the Offer is extended or (iv) subject to the
provisions of next paragraph, amend the Offer.
 
  Subject to the terms of the Merger Agreement and applicable rules and
regulations of the Commission may, under certain circumstances, (a) extend the
period of time during which the Offer is open and thereby delay acceptance for
payment of and the payment for any Shares, by giving oral or written notice of
such extension to the Depositary and (b) amend the Offer in any other respect
by giving oral or written notice of such amendment to the Depositary. UNDER NO
CIRCUMSTANCES WILL INTEREST BE PAID ON THE PURCHASE PRICE FOR TENDERED SHARES,
WHETHER OR NOT PURCHASER EXERCISES ITS RIGHT TO EXTEND THE OFFER.
 
  Under the Merger Agreement, the Purchaser has the right, in its sole
discretion, to modify and make changes to the terms and conditions of the
Offer, provided that without the prior consent of the Company, no modification
or change may be made which (i) decreases the consideration payable in the
Offer, (ii) changes the form of consideration payable in the Offer (other than
by adding consideration), (iii) changes the Minimum Condition, provided that
Purchaser may reduce the Minimum Condition to an amount of Shares which is not
less than a
 
                                       4
<PAGE>
 
majority of the Fully Diluted Shares so long as the affirmative vote of such
amount of Shares would provide the requisite shareholder approval for an
amendment to the Company's Certificate of Incorporation reducing the vote
required to approve a merger to a majority of the outstanding Shares, (iv)
decreases the maximum number of Shares sought pursuant to the Offer, (v)
adversely changes any conditions to the Offer, or (vi) imposes additional
conditions to the Offer. Notwithstanding the foregoing, Purchaser may, without
the consent of the Company, (i) extend the Offer on one or more occasions for
such period as may be determined by Purchaser in its sole discretion (each
such extension period not to exceed 10 business days at a time), if at the
then scheduled Expiration Date any of the conditions to Purchaser's
obligations to accept for payment and pay for Shares shall not be satisfied or
waived, (ii) extend the Offer for any period required by any rule, regulation,
interpretation or position of the Commission or the staff thereof applicable
to the Offer, and (iii) extend the Offer on one occasion for a period of not
more than 10 business days if the Minimum Condition has been satisfied but
less than 90% of the Fully Diluted Shares have been validly tendered and not
properly withdrawn. Notwithstanding the foregoing, Purchaser may not, without
the Company's prior written consent, extend the Offer pursuant to clause (i)
of the preceding sentence if the events or circumstances set forth in Section
15 shall have occurred as a result of Parent or Purchaser's breach of the
Merger Agreement. The conditions to the Offer are for the benefit of Purchaser
and, except with respect to the Minimum Condition, may be waived by Purchaser,
in whole or in part at any time and from time to time, in its sole discretion.
 
  Any extension, delay, waiver, amendment or termination of the Offer will be
followed as promptly as practicable by public announcement thereof, the
announcement in the case of an extension to be issued no later than 9:00 a.m.,
New York City time, on the next business day after the previously scheduled
Expiration Date in accordance with Rules 14d-4(c), 14d-6(d) and 14e-1(d) under
the Exchange Act, which require that material changes be promptly disseminated
to holders of Shares. Subject to applicable law and without limiting the
obligation of Purchaser under such Rules or the manner in which Purchaser may
choose to make any public announcement, Purchaser will not have any obligation
to publish, advertise or otherwise communicate any such public announcement
other than by making a press release to the Dow Jones News Service. As used in
this Offer to Purchase, "business day" has the meaning set forth in Rule 14d-1
under the Exchange Act.
 
  If Purchaser extends the Offer, or if Purchaser (whether before or after its
acceptance for payment of Shares) is delayed in its purchase of, or payment
for, Shares or is unable to pay for Shares pursuant to the Offer for any
reason, then, without prejudice to Purchaser's rights under the Offer, the
Depositary may retain tendered Shares on behalf of Purchaser, and such Shares
may not be withdrawn except to the extent tendering stockholders are entitled
to the withdrawal rights described in Section 4. However, the ability of
Purchaser to delay the payment for Shares which Purchaser has accepted for
payment is limited by Rule 14e-1(c) under the Exchange Act, which requires
that a bidder pay the consideration offered or return the securities deposited
by, or on behalf of, holders of securities promptly after the termination or
withdrawal of the Offer.
 
  If Purchaser makes a material change in the terms of the Offer or the
information concerning the Offer or waives a material condition of the Offer,
Purchaser will disseminate additional tender offer materials and extend the
Offer to the extent required by Rules 14d-4(c), 14d-6(d) and 14e-1 under the
Exchange Act. The minimum period during which the Offer must remain open
following material changes in the terms of the Offer or information concerning
the Offer, other than a change in price or a change in percentage of
securities sought, will depend upon the facts and circumstances then existing,
including the relative materiality of the changed terms or information. In a
public release, the Commission has stated its view that an offer must remain
open for a minimum period of time following a material change in the terms of
such
 
                                       5
<PAGE>
 
offer and that waiver of a material condition, such as the Minimum Condition,
is a material change in the terms of such offer. The release states that an
offer should remain open for a minimum of five business days from the date a
material change is first published, or sent or given to security holders and
that, if material changes are made with respect to information not materially
less significant than the offer price and the number of shares being sought, a
minimum of 10 business days may be required to allow adequate dissemination
and investor response. The requirement to extend the Offer will not apply to
the extent that the number of business days remaining between the occurrence
of the change and the then scheduled Expiration Date equals or exceeds the
minimum extension period that would be required because of such amendment. If,
prior to the Expiration Date, Purchaser increases the consideration offered to
holders of Shares pursuant to the Offer, such increased consideration will be
paid to all holders whose Shares are purchased in the Offer whether or not
such Shares were tendered prior to such increase.
 
  The Company has provided Purchaser with the Company's stockholder lists and
security position listings for the purpose of disseminating the Offer to
holders of Shares. This Offer to Purchase and the related Letter of
Transmittal will be mailed to record holders of Shares and will be furnished
to brokers, dealers, commercial banks, trust companies and similar persons
whose names, or the names of whose nominees, appear on the stockholder lists
or, if applicable, who are listed as participants in a clearing agency's
security position listing, for subsequent transmittal to beneficial owners of
Shares.
 
  2. ACCEPTANCE FOR PAYMENT AND PAYMENT. Upon the terms and subject to the
conditions of the Offer (including, if the Offer is extended or amended, the
terms and conditions of any such extension or amendment), Purchaser will
accept for payment and will pay for all Shares validly tendered prior to the
Expiration Date and not properly withdrawn in accordance with Section 4
promptly after the later to occur of (i) the Expiration Date and (ii) the
satisfaction or waiver of the conditions of the Offer set forth in Section 15
related to regulatory matters. Any determination concerning the satisfaction
of such terms and conditions shall be within the sole discretion of Purchaser.
See Section 4.
 
  The Purchaser expressly reserves the right, in its sole discretion, to delay
acceptance for payment of, or payment for, Shares in order to comply in whole
or in part with any applicable law, including without limitation the HSR Act.
See Section 16. If Purchaser is delayed in its acceptance for payment of, or
payment for (whether before or after its acceptance for payment of Shares),
Shares or is unable to accept for payment or pay for Shares pursuant to the
Offer for any reason, then, without prejudice to Purchaser's rights under the
Offer (including such rights as are set forth in Sections 1 and 15) (but
subject to compliance with Rule 14e-1(c) under the Exchange Act, which
requires that a tender offeror pay the consideration offered or return the
tendered securities promptly after termination or withdrawal of a tender
offer), the Depositary may, nevertheless, on behalf of Purchaser, retain
tendered Shares, and such Shares may not be withdrawn except to the extent
tendering stockholders are entitled to exercise, and duly exercise, withdrawal
rights as described in Section 4.
 
  For purposes of the Offer, Purchaser will be deemed to have accepted for
payment, and thereby purchased, Shares properly tendered to Purchaser and not
withdrawn, if, as and when Purchaser gives oral or written notice to the
Depositary of its acceptance for payment of such Shares. Upon the terms and
subject to the conditions of 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 tendering
stockholders for the purpose of receiving payment from Purchaser and
transmitting payment to tendering stockholders. In all cases, payment for
Shares accepted for payment pursuant to the Offer will be made only after
timely
 
                                       6
<PAGE>
 
receipt by the Depositary of (i) certificates for such Shares (or a timely
Book Entry Confirmation (as defined below) with respect thereto), (ii) a
Letter of Transmittal (or facsimile thereof), properly completed and duly
executed, with any required signature guarantees, or, in the case of a book-
entry transfer, an Agent's Message (as defined below) and (iii) any other
documents required by the Letter of Transmittal. Accordingly, payment may be
made to tendering stockholders at different times if delivery of the Shares
and other required documents occur at different times. The per Share
consideration paid to any holder of Shares pursuant to the Offer will be the
highest per Share consideration paid to any other holder of such Shares
pursuant to the Offer.
 
  UNDER NO CIRCUMSTANCES WILL INTEREST BE PAID ON THE PURCHASE PRICE TO BE
PAID BY PURCHASER FOR THE SHARES, REGARDLESS OF ANY EXTENSION OF THE OFFER OR
ANY DELAY IN MAKING SUCH PAYMENT.
 
  If any tendered Shares are not purchased pursuant to the Offer for any
reason, or if certificates are submitted representing more Shares than are
tendered, certificates evidencing Shares not tendered or not accepted for
purchase will be returned to the tendering stockholder, or such other person
as the tendering stockholder shall specify in the Letter of Transmittal, as
promptly as practicable following the expiration, termination or withdrawal of
the Offer. In the case of Shares delivered by book-entry transfer into the
Depositary's account at the Book-Entry Transfer Facility pursuant to the
procedures set forth in Section 3, such Shares will be credited to such
account maintained at the Book-Entry Transfer Facility as the tendering
stockholder shall specify in the Letter of Transmittal, as promptly as
practicable following the expiration, termination or withdrawal of the Offer.
If no such instructions are given with respect to Shares delivered by book-
entry transfer, any such Shares not tendered or not purchased will be returned
by crediting the account at the Book-Entry Transfer Facility designated in the
Letter of Transmittal as the account from which such Shares were delivered.
 
  Purchaser reserves the right to transfer or assign, in whole or, from time
to time, in part, to one or more of its affiliates, the right to purchase
Shares tendered pursuant to the Offer, but any such transfer or assignment
will not relieve Purchaser of its obligations under the Offer and will in no
way prejudice the rights of tendering stockholders to receive payment for
Shares validly tendered and accepted for payment pursuant to the Offer.
 
  3. PROCEDURES FOR TENDERING SHARES.
 
  Valid Tender. For Shares to be validly tendered pursuant to the Offer,
either (i) a properly completed and duly executed Letter of Transmittal (or
facsimile thereof), together with any required signature guarantees, or in the
case of a book-entry transfer, an Agent's Message, and any other required
documents, must be received by the Depositary at one of its addresses set
forth on the back cover of this Offer to Purchase prior to the Expiration Date
and either certificates evidencing tendered Shares must be received by the
Depositary at one of such addresses or such Shares must be delivered to the
Depositary pursuant to the procedures for book-entry transfer set forth below
and a Book-Entry Confirmation must be received by the Depositary, in each case
prior to the Expiration Date, or (ii) the tendering stockholder must comply
with the guaranteed delivery procedures described below.
 
  If certificates evidencing tendered Shares are forwarded to the Depositary
in multiple deliveries, a properly completed and duly executed Letter of
Transmittal (or a facsimile thereof) must accompany each delivery. No
alternative, conditional or contingent tenders will be accepted and no
fractional Shares will be purchased.
 
  Book-Entry Transfer. The Depositary will establish an account with respect
to the Shares at The Depository Trust Company (the "Book-Entry Transfer
Facility") for purposes of the Offer
 
                                       7
<PAGE>
 
within two business days after the date of this Offer to Purchase. Any
financial institution that is a participant in the Book-Entry Transfer
Facility's system may make book-entry delivery of Shares by causing the Book-
Entry Transfer Facility to transfer such Shares into the Depositary's account
in accordance with such Book-Entry Transfer Facility's procedures for such
transfer. However, although delivery of Shares may be effected through book-
entry transfer into the Depositary's account at the Book-Entry Transfer
Facility, the Letter of Transmittal (or facsimile thereof), properly completed
and duly executed, with any required signature guarantees, or an Agent's
Message, and any other required documents must, in any case, be transmitted
to, and received by, the Depositary at one of its addresses set forth on the
back cover of this Offer to Purchase prior to the Expiration Date, or the
tendering stockholder must comply with the guaranteed delivery procedures
described below. The confirmation of a book-entry transfer of Shares into the
Depositary's account at the Book-Entry Transfer Facility as described above is
referred to herein as a "Book-Entry Confirmation."
 
  THE LETTER OF TRANSMITTAL AND ANY OTHER REQUIRED DOCUMENT MUST BE
TRANSMITTED TO AND RECEIVED BY THE DEPOSITARY AT ONE OF ITS ADDRESSES SET
FORTH ON THE BACK COVER PAGE OF THIS OFFER TO PURCHASE. DELIVERY OF THE LETTER
OF TRANSMITTAL AND ANY OTHER REQUIRED DOCUMENTS TO THE BOOK-ENTRY TRANSFER
FACILITY WILL NOT CONSTITUTE DELIVERY TO THE DEPOSITARY.
 
  The term "Agent's Message" means a message transmitted by the Book-Entry
Transfer Facility to, and received by, the Depositary and forming a part of a
Book-Entry Confirmation, which states that such Book-Entry Transfer Facility
has received an express acknowledgment from the participant in such Book-Entry
Transfer Facility tendering the Shares that such participant has received and
agrees to be bound by the terms of the Letter of Transmittal and that
Purchaser may enforce such agreement against such participant.
 
  THE METHOD OF DELIVERY OF SHARES, THE LETTER OF TRANSMITTAL AND ALL OTHER
REQUIRED DOCUMENTS, INCLUDING DELIVERY THROUGH THE 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, REGISTERED MAIL WITH RETURN RECEIPT REQUESTED,
PROPERLY INSURED, IS RECOMMENDED. IN ALL CASES, SUFFICIENT TIME SHOULD BE
ALLOWED TO ENSURE TIMELY DELIVERY.
 
  Signature Guarantees. No signature guarantee is required on the Letter of
Transmittal (i) if the Letter of Transmittal is signed by the registered
holder(s) (which term, for purposes of this Section, includes any participant
in the Book Entry Transfer Facility's systems whose name appears on a security
position listing as the owner of the Shares) of Shares tendered therewith and
such registered holder has not completed either the box entitled "Special
Delivery Instructions" or the box entitled "Special Payment Instructions" on
the Letter of Transmittal or (ii) if such Shares are tendered for the account
of a financial institution (including most commercial banks, savings and loan
associations and brokerage houses) that is a participant in the Security
Transfer Agents Medallion Program, the New York Stock Exchange Medallion
Signature Guarantee Program or the Stock Exchange Medallion Program or by any
other "eligible guarantor institution," as such term is defined in Rule 17Ad-
15 under the Exchange Act (each, an "Eligible Institution" and, collectively,
"Eligible Institutions"). In all other cases, all signatures on Letters of
Transmittal must be guaranteed by an Eligible Institution. See Instructions 1
and 5 to the Letter of Transmittal. If the certificates for Shares are
registered in the name of a person other than the signer of the Letter of
Transmittal, or if payment is to be made, or certificates for Shares not
tendered or not accepted for payment are to be returned, to a person other
than the registered holder of the certificates surrendered, then the tendered
certificates for such Shares 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 appear
 
                                       8
<PAGE>
 
on the certificates, with the signatures on the certificates or stock powers
guaranteed as described above. See Instructions 1 and 5 to the Letter of
Transmittal.
 
  Guaranteed Delivery. If a stockholder desires to tender Shares pursuant to
the Offer and such stockholder's certificates for Shares are not immediately
available or the procedures for book-entry transfer cannot be completed on a
timely basis or time will not permit all required documents to reach the
Depositary prior to the Expiration Date, such stockholder's tender may be
effected if all the following conditions are met:
 
    (i) such tender is made by or through an Eligible Institution;
 
    (ii) a properly completed and duly executed Notice of Guaranteed
  Delivery, substantially in the form provided by Purchaser, is received by
  the Depositary, as provided below, prior to the Expiration Date; and
 
    (iii) the certificates, in proper form for transfer, for (or a Book-Entry
  Confirmation with respect to) such tendered Shares, together with a
  properly completed and duly executed Letter of Transmittal (or facsimile
  thereof), with any required signature guarantees, or, in the case of a
  book-entry transfer, an Agent's Message, and any other required documents,
  are received by the Depositary within three trading days after the date of
  execution of such Notice of Guaranteed Delivery. 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 mailed to the Depositary
and must include a guarantee by an Eligible Institution in the form set forth
in such Notice of Guaranteed Delivery.
 
  Notwithstanding any other provision hereof, payment for Shares accepted for
payment pursuant to the Offer will in all cases be made only after timely
receipt by the Depositary of (a) certificates for (or a timely Book-Entry
Confirmation with respect to) such Shares, (b) a Letter of Transmittal (or a
facsimile thereof), properly completed and duly executed, with any required
signature guarantees, or, in the case of a book-entry transfer, an Agent's
Message, 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 Book-Entry Confirmations with respect to
such Shares are actually received by the Depositary.
 
  The valid tender of Shares pursuant to one of the procedures described above
will constitute a binding agreement between the tendering stockholder and
Purchaser upon the terms and subject to the conditions of the Offer.
 
  Appointment. By executing the Letter of Transmittal as set forth above
(including delivery through an Agent's Message), the tendering stockholder
will irrevocably appoint designees of Parent as such stockholder's attorneys-
in-fact and proxies in the manner set forth in the Letter of Transmittal, each
with full power of substitution, to the full extent of such stockholder's
rights with respect to the Shares tendered by such stockholder and accepted
for payment by Purchaser and with respect to any and all non-cash dividends,
distributions, rights, other Shares or other securities issued or issuable in
respect of such Shares on or after December 20, 1998 (collectively,
"Distributions"). However, cash dividends that the Company is permitted to
declare and pay prior to the consummation of the Offer, including the $0.14
per Share dividend payable on January 15, 1999 to stockholders of record on
January 4, 1999, will be paid to tendering stockholders to the extent so
declared and paid. All such proxies will be considered coupled with an
interest in the tendered Shares. Such appointment will be effective if, as and
when, and only to the extent that, Purchaser accepts for payment Shares
tendered by such stockholder as provided herein. All such powers of attorney
and proxies will be irrevocable and
 
                                       9
<PAGE>
 
will be deemed granted in consideration of the acceptance for payment by
Purchaser of Shares tendered in accordance with the terms of the Offer. Upon
such appointment, all prior powers of attorney, proxies and consents given by
such stockholder with respect to such Shares (and any and all Distributions)
will, without further action, be revoked and no subsequent powers of attorney,
proxies, consents or revocations may be given by such stockholder (and, if
given, will not be deemed effective). The designees of Purchaser will thereby
be empowered to exercise all voting and other rights with respect to such
Shares (and any and all Distributions), including, without limitation, in
respect of any annual or special meeting of the Company's stockholders (and
any adjournment or postponement thereof), actions by written consent in lieu
of any such meeting or otherwise, as each such attorney-in-fact and proxy or
his substitute shall in his sole discretion deem proper. Purchaser reserves
the right to require that, in order for Shares to be deemed validly tendered,
immediately upon Purchaser's acceptance for payment of such Shares, Purchaser
must be able to exercise full voting, consent and other rights with respect to
such Shares (and any and all Distributions), including voting at any meeting
of stockholders.
 
  Determination of Validity. All questions as to the validity, form,
eligibility (including time of receipt) and acceptance for payment of any
tender of Shares will be determined by Purchaser, in its sole discretion,
which determination will be final and binding. Purchaser reserves the absolute
right to reject any or all tenders of any Shares determined by it not to be in
proper form or the acceptance for payment of which, or payment for which, may,
in the opinion of Purchaser's counsel, be unlawful. Purchaser also reserves
the absolute right, in its sole discretion, to waive any defect or
irregularity in any tender of Shares of any particular stockholder, whether or
not similar defects or irregularities are waived in the case of other
stockholders. No tender of Shares will be deemed to have been validly made
until all defects or irregularities relating thereto have been cured or
waived. None of Purchaser, Parent, the Depositary, the Information Agent or
any other person will be under any duty to give notification of any defects or
irregularities in tenders or incur any liability for failure to give any such
notification. Purchaser's interpretation of the terms and conditions of the
Offer (including the Letter of Transmittal and the instructions thereto) will
be final and binding.
 
  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, or its assignee (in either case, the "Payee") must,
unless an exemption applies, provide the Depositary with such Payee'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 Payee is not
subject to backup withholding. If a Payee does not provide such Payee's
correct TIN or fails to provide the certifications described above, the
Internal Revenue Service (the "IRS") may impose a penalty on such Payee and
payment of cash to such Payee pursuant to the Offer may be subject to backup
withholding of 31%. All stockholders surrendering Shares pursuant to the Offer
and other Payees should complete and sign the Substitute Form W-9 included as
part of the Letter of Transmittal to provide the information and certification
necessary to avoid backup withholding (unless an applicable exemption exists
and is proved in a manner satisfactory to the Purchaser and the Depositary).
Certain Payees (including, among others, all corporations and certain foreign
individuals and entities) are not subject to backup withholding. Noncorporate
foreign stockholders should complete and sign a Form W-8, Certificate of
Foreign Status, a copy of which may be obtained from the Depositary, in order
to avoid backup withholding. See Instruction 10 to the Letter of Transmittal.
 
  Options. Holders of currently exercisable Options may exercise such Options
pursuant to their terms and tender the Shares received upon such exercise
pursuant to the Offer. Alternatively, holders of unexercised Options will
receive cash payments after the Effective Time in respect of such unexercised
Options. See Section 12 under "--Options."
 
 
                                      10
<PAGE>
 
  4. WITHDRAWAL RIGHTS. Except as otherwise provided in this Section 4 or as
provided by applicable law, tenders of Shares are irrevocable. Shares tendered
pursuant to the Offer may be withdrawn pursuant to the procedures set forth
below at any time prior to the Expiration Date and, unless theretofore
accepted for payment by Purchaser pursuant to the Offer, may also be withdrawn
at any time after February 20, 1999.
 
  For a withdrawal to be effective, a written, telegraphic or facsimile
transmission notice of withdrawal must be timely received by the Depositary at
one of its addresses set forth on the back cover of this Offer to Purchase.
Any such notice of withdrawal must specify the name of the person who tendered
the Shares to be withdrawn, the number of Shares to be withdrawn and the name
of the registered holder of the Shares to be withdrawn, if different from the
name of the person who tendered the Shares. If certificates evidencing Shares
to be withdrawn have been delivered or otherwise identified to the Depositary,
then, prior to the physical release of such certificates, the serial numbers
shown on such certificates must be submitted to the Depositary and, unless
such Shares have been tendered by an Eligible Institution, the signatures on
the notice of withdrawal must be guaranteed by an Eligible Institution. If
Shares have been delivered pursuant to the procedures for book-entry transfer
as set forth in Section 3, any notice of withdrawal must also specify the name
and number of the account at the Book-Entry Transfer Facility to be credited
with the withdrawn Shares and otherwise comply with such Book-Entry Transfer
Facility's procedures.
 
  Withdrawals of tendered Shares may not be rescinded, and any Shares properly
withdrawn will thereafter be deemed not validly tendered for purposes of the
Offer. However, withdrawn Shares may be retendered by again following one of
the procedures described in Section 3 at any time prior to the Expiration
Date.
 
  All questions as to the form and validity (including time of receipt) of
notices of withdrawal will be determined by Purchaser, in its sole discretion,
which determination will be final and binding. None of Purchaser, Parent, the
Dealer Manager, the Depositary, the Information Agent or any other person will
be under any duty to give notification of any defects or irregularities in any
notice of withdrawal or incur any liability for failure to give any such
notification.
 
  5. CERTAIN U.S. FEDERAL INCOME TAX CONSEQUENCES. The following is a general
summary of certain U.S. Federal income tax consequences of the Offer and the
Merger relevant to a beneficial holder of Shares whose Shares are tendered and
accepted for payment pursuant to the Offer or whose Shares are converted to
cash in the Merger (a "Holder"). The discussion is based on the Internal
Revenue Code of 1986, as amended (the "Code"), regulations issued thereunder,
judicial decisions and administrative rulings, all of which are subject to
change, possibly with retroactive effect. The following discussion does not
address the U.S. Federal income tax consequences to all categories of Holders
that may be subject to special rules (e.g., holders who acquired their Shares
pursuant to the exercise of employee stock options or other compensation
arrangements with the Company, holders who perfect applicable appraisal rights
under the NYBCL, foreign holders, insurance companies, tax-exempt
organizations, dealers in securities and persons who have acquired the Shares
as part of a straddle, hedge, conversion transaction or other integrated
investment), nor does it address the Federal income tax consequences to
persons who do not hold the Shares as "capital assets" within the meaning of
Section 1221 of the Code (generally, property held for investment). Holders
should consult their own tax advisors regarding the U.S. Federal, state, local
and foreign income and other tax consequences of the Offer and the Merger.
 
  The receipt of cash for Shares pursuant to the Offer or the Merger will be a
taxable transaction for U.S. Federal income tax purposes and may also be a
taxable transaction under
 
                                      11
<PAGE>
 
applicable state, local and foreign income and other tax laws. In general, a
Holder who sells Shares pursuant to the Offer or receives cash in exchange for
Shares pursuant to the Merger will recognize gain or loss for Federal income
tax purposes equal to the difference, if any, between the amount of cash
received and the Holder's adjusted tax basis in the Shares sold pursuant to
the Offer or surrendered for cash pursuant to the Merger. Gain or loss will be
determined separately for each block of Shares (i.e., Shares acquired at the
same cost in a single transaction) tendered pursuant to the Offer or
surrendered for cash pursuant to the Merger. Such gain or loss will be long-
term capital gain or loss if the Holder has held the Shares for more than one
year at the time of the consummation of the Offer or the Merger. Capital gains
recognized by an individual investor (or an estate or certain trusts) upon a
disposition of a Share that has been held for more than one year generally
will be subject to a maximum tax rate of 20% or, in the case of a Share that
has been held for one year or less, will be subject to tax at ordinary income
rates. Certain limitations apply to the use of capital losses.
 
  6. PRICE RANGE OF THE SHARES; DIVIDENDS ON THE SHARES. The Shares are listed
on the NYSE under the symbol "LRI". The following table sets forth, for each
of the fiscal quarters indicated, the high and low sales price per Share on
the NYSE and the amount of cash dividends paid per Share, as reported in
published financial sources.

  Note: Share prices and dividend amounts reflect the 3-for-2 stock split
        effective August 19, 1997.
 
  On December 18, 1998, the last full trading day prior to the public
announcement of the execution of the Merger Agreement by the Company, Parent
and Purchaser, the last reported closing sales price of the Shares on the NYSE
was $26.81 per Share. On December 22, 1998, the last full trading day prior to
the commencement of the Offer, the last reported sales price of the Shares on
the NYSE was $33.75 per Share. STOCKHOLDERS ARE URGED TO OBTAIN A CURRENT
MARKET QUOTATION FOR THE SHARES.
 
  Under the terms of the Merger Agreement, the Company is not permitted to
declare or pay dividends with respect to the Shares without the prior written
consent of Parent except that the Company may declare and pay to holders of
Shares regular quarterly cash dividends not to exceed $0.14 per Share per
fiscal quarter, including the quarterly cash dividend of $0.14 per Share
declared on December 20, 1998 and scheduled to be paid on January 15, 1999 to
stockholders of record on January 4, 1999.

  7. EFFECT OF THE OFFER ON THE MARKET FOR THE SHARES; STOCK LISTING; EXCHANGE
ACT REGISTRATION; MARGIN REGULATIONS.
 
  Market for the Shares. The purchase of Shares by Purchaser pursuant to the
Offer will reduce the number of holders of Shares and the number of Shares
that might otherwise trade publicly and, depending upon the number of Shares
so purchased, could adversely affect the liquidity and market value of the
remaining Shares held by the public.
 
  Stock Listing. The Shares are listed on the NYSE. Depending upon the number
of Shares purchased pursuant to the Offer, the Shares may no longer meet the
requirements for continued listing on the NYSE and may therefore be delisted
from the NYSE. According to the NYSE's published guidelines, the NYSE would
consider delisting the Shares if, among other things: (i) the number of record
holders of 100 or more Shares should fall below 1,200; (ii) the number of
publicly held Shares (exclusive of holdings of Parent and Purchaser and any
other subsidiaries or affiliates of Parent and of officers or directors of the
Company or their immediate families or other concentrated holdings of 10% or
more ("Excluded Holdings")) should fall below 600,000; or (iii) the aggregate
market value of such publicly held Shares (exclusive of Excluded Holdings)
should fall below $5,000,000.
 
  If the NYSE were to delist the Shares, it is possible that the Shares would
continue to trade on other securities exchanges or in the over-the-counter
market and that price quotations would be reported by such exchanges or
through the National Association of Securities Dealers Automated Quotation
System ("NASDAQ") or other sources. However, the extent of the public market
for the Shares and the availability of such quotations would depend upon such
factors as the number of stockholders and/or the aggregate market value of the
publicly-traded Shares remaining at such time, the interest in maintaining a
market in the Shares on the part of securities firms, the possible termination
of registration under the Exchange Act as described below and other factors.
 
  Exchange Act Registration. The Shares are currently registered under the
Exchange Act. Registration of the Shares under the Exchange Act may be
terminated upon application of the Company to the Commission if the Shares are
not listed on a national securities exchange, quoted on an automated inter-
dealer quotation system or held by 300 or more holders of record. Termination
of registration of the Shares under the Exchange Act would substantially
reduce the information required to be furnished by the Company to its
stockholders and to the Commission and would make certain provisions of the
Exchange Act no longer applicable to the Company, such as the short-swing
profit recovery provisions of Section 16(b), the requirement of furnishing a
proxy statement pursuant to Section 14(a) in connection with stockholders'
meetings and the related requirement of furnishing an annual report to
stockholders and the requirements of Rule 13e-3 under the Exchange Act with
respect to "going private" transactions. Furthermore, the ability of
"affiliates" of the Company and persons holding "restricted securities" of the
Company to dispose of such securities pursuant to Rule 144 or Rule 144A
promulgated under the Securities Act of 1933, as amended (the "Securities
Act"), may be impaired or eliminated.
 
  Purchaser currently intends not to seek delisting of the Shares from the
NYSE and the termination of the registration of the Shares under the Exchange
Act prior to the Effective Time, although such Shares may be delisted by the
NYSE as described above. If the NYSE listing and the Exchange Act registration
of the Shares are not terminated prior to the Merger, then the Shares will be
delisted from the NYSE and the registration of the Shares under the Exchange
Act will be terminated following the consummation of the Merger. See Section
13 with respect to the interrelationship of the status of the listing of the
Shares and the availability of appraisal rights with respect to the Merger.
 
 
                                      13
<PAGE>
 
  Margin Regulations. The Shares are presently "margin securities" under the
regulations of the Board of Governors of the Federal Reserve System (the
"Federal Reserve Board"), which status has the effect, among other things, of
allowing brokers to extend credit on the collateral of the Shares. Depending
upon factors similar to those described above regarding stock exchange listing
and market quotations, it is possible that, following the Offer, the Shares
would no longer constitute "margin securities" for the purposes of the margin
regulations of the Federal Reserve Board and therefore could no longer be used
as collateral for loans made by brokers. In addition, if registration of the
Shares under the Exchange Act were terminated, the Shares would no longer
constitute "margin securities."

  Other Financial Information. During the course of the discussions between

Company provided Parent or its representatives with certain information about
the Company and its financial performance which is not publicly available. The
information provided included financial projections for the Company as an

transaction with Parent and Purchaser). The following is a summary of selected

  The Company has advised Purchaser and Parent that it does not as a matter of
course make public any projections as to future performance or earnings, and
the projections set forth above are included in this Offer only because the
information was provided to Parent and Purchaser.
 
                                      15
<PAGE>
 
The projections were not prepared with a view to public disclosure or
compliance with the published guidelines of the Commission or the guidelines
established by the American Institute of Certified Public Accountants
regarding projections or forecasts. The Company has advised Parent and
Purchaser that its internal operating projections are, in general, prepared
solely for internal use and capital budgeting and other management decisions
and are subjective in many respects and thus susceptible to various
interpretations and periodic revision based on actual experience and business
developments. The projections were based on a number of assumptions some of
which are beyond the control of the Company, Purchaser or Parent or their
respective financial advisors and representatives and some of which inevitably
will prove to be incorrect. Such assumptions include, but are not limited to
(i) the Company's gross profit margin increasing consistently over the periods
covered by the projections, (ii) significant increases in process sales and
precious metal content sales over the periods covered by the projections,
(iii) sales, general and administrative expenses as a percentage of sales
decreasing over the period covered by the projections, and (iv) an effective
tax rate of 28% through 2001. Although the Company has advised Parent and
Purchaser that it believes the assumptions used in preparing this information
were reasonable when made, no prediction can be made as to whether such
assumptions were or will be accurate; accordingly, there can be no assurance,
and no representation or warranty is made, that actual results will not vary
materially from those described above. The foregoing information is forward-
looking in nature and inherently subject to significant uncertainties and
contingencies, many of which are beyond the control of the Company, including
industry performance, general business and economic conditions, currency
exchange rates, customer requirements, competition, adverse changes in
applicable laws, regulations or rules governing environmental, tax and
accounting matters and other matters. The inclusion of this information should
not be regarded as an indication that Parent, Purchaser, the Company or anyone
who received this information then considered, or now considers, it a reliable
prediction of future events, and this information should not be relied on as
such. None of Parent or Purchaser or any of their respective financial
advisors or the Dealer Manager assumes any responsibility for the validity,
reasonableness, accuracy or completeness of the projections, and the Company
has made no representation to Parent or Purchaser regarding the projections
described above. None of the Company, Purchaser, Parent or any of their
respective financial advisors or the Dealer Manager intends to update, revise
or correct such projections if they become inaccurate (even in the short
term). The projections have not been adjusted to reflect the effects of the
Offer or the Merger.

requirements of the Exchange Act and, in accordance therewith, is obligated to

  The name, citizenship, business address, present principal occupation and
material positions held during the past five years of each of the executive
officers and directors of Parent and Purchaser are set forth in Schedule I to
this Offer to Purchase.
 
                                      18
<PAGE>
 
  Except as set forth in this Offer to Purchase and except for 100 Shares
acquired by Parent on October 5, 1998 at a price per Share of $18.87, none of
Purchaser, Parent, or to the best knowledge of Purchaser and Parent, any of
the persons listed on Schedule I hereto or any associate or majority owned
subsidiary of Purchaser, Parent or any of the persons so listed, beneficially
owns or has a right to acquire, directly or indirectly, any Shares, and none
of Purchaser or Parent, or to the best knowledge of Purchaser and Parent, any
of the persons or entities referred to above, nor any of the respective
executive officers, directors or subsidiaries of any of the foregoing, has
effected any transaction in the Shares during the past 60 days.
 
  Except as set forth in this Offer to Purchase, none of Purchaser, Parent or,
to the best knowledge of Purchaser and Parent, any of the persons listed on
Schedule I hereto, has any contract, arrangement, understanding or
relationship with any other person with respect to any securities of the
Company, including, but not limited to, any contract, arrangement,
understanding or relationship concerning the transfer or the voting of any
securities of the Company, joint ventures, loan or option arrangements, puts
or calls, guarantees of loans, guarantees against loss or the giving or
withholding of proxies.
 
  Except as set forth in this Offer to Purchase, none of Purchaser, Parent,
any of their respective affiliates, nor, to the best knowledge of Purchaser or
Parent, any of the persons listed on Schedule I, has had, since March 1, 1995,
any business relationships or transactions with the Company or any of its
executive officers, directors or affiliates that would be required to be
reported under the rules of the Commission applicable to the Offer. Except as
set forth in this Offer to Purchase, since March 1, 1995 there have been no
contacts, negotiations or transactions between Purchaser, Parent, any of their
respective affiliates or, to the best knowledge of Purchaser or Parent, any of
the persons listed on Schedule I, and the Company or its affiliates concerning
a merger, consolidation or acquisition, tender offer or other acquisition of
securities, election of directors or a sale or other transfer of a material
amount of assets.
 
  10. SOURCES AND AMOUNT OF FUNDS.
 
  The Offer is not conditioned upon any financing arrangements. Purchaser
estimates that the total amount of funds required by Purchaser to consummate
the Offer and the Merger, including the fees and expenses of the Offer and the
Merger and refinancing of existing indebtedness of the Company, is
approximately $460 million. Purchaser will obtain all such funds from Parent
in the form of capital contributions or advances. Parent anticipates funding
the capital contributions or advances through one or more of a combination of
cash on hand and other internally generated funds, commercial paper, privately
placed notes, and arranged bank credit facilities.
 
  It is anticipated that any indebtedness incurred by Parent in connection
with the Offer and the Merger will be repaid from funds generated internally
by Parent and its subsidiaries (including, after the Merger, if consummated,
funds generated by the Surviving Corporation and its subsidiaries), proceeds
of dispositions, through other sources which may include the proceeds of
future bank refinancings, dispositions or the public or private sale of debt
or equity securities, or through a combination of two or more such sources. No
final decisions have been made, however, concerning the method Parent will
employ to repay any such indebtedness. Such decisions, when made, will be
based on Parent's review from time to time of the advisability of particular
actions, as well as on prevailing interest rates and financial and other
economic conditions.
 
  11. BACKGROUND OF THE OFFER; CONTACTS WITH THE COMPANY.
 
  Shipley Company ("Shipley"), a wholly owned subsidiary of Parent
headquartered in Marlboro, Massachusetts, is the cornerstone of Parent's
Electronics Materials business, which
 
                                      19
<PAGE>
 
reported sales of approximately $400 million in 1997. Shipley is a leading
supplier of specialized products and technology to producers of both
semiconductors and printed wiring boards. As part of its strategy to
significantly grow the Electronics Materials business, Parent identified the
Company as an attractive acquisition candidate in view of the complementary
fit of products, technologies, geographic reach and culture between Shipley
and the Company.
 
  On June 4, 1998, Michael S. Foster, Vice President of Shipley, raised with
Richard Kessler, Executive Vice President and Chief Operating Officer of the
Company, the possibility of exploring a business combination or other
opportunity for cooperation between the Company and Parent.
 
  On June 17 and 18, Mr. Foster and Mr. Kessler discussed further the
potential benefits of a possible transaction between Parent and the Company.
 
  On July 22, 1998, Mr. Kessler called Mr. Foster to advise him that the
Company Board had authorized informal discussions regarding the possible
acquisition of the Company by Parent.
 
  On July 29, 1998, Mr. Foster and Pierre R. Brondeau, President of Shipley,
met for lunch in New York City with Mr. Kessler and David Rosenthal, Vice
President--Finance and Treasurer of the Company, to follow up on the June 17-
18 conversations. Messrs. Foster and Brondeau stated that Parent was
interested in exploring on a preliminary basis the potential merits of a
business combination.
 
  On August 25, 1998, Ronald F. Ostrow, President and Chief Executive Officer
of the Company, and Messrs. Kessler and Rosenthal visited the Shipley facility
in Marlboro, Massachusetts. During that visit, Messrs. Brondeau and Foster
discussed the possible acquisition of the Company by Parent. Mr. Ostrow stated
that any transaction should involve a price representing a premium above the
recent stock market high for the Shares ($32 per Share). The parties also
explored the strategic and cultural fit between the two companies and agreed
to meet again the following month.
 
  On September 16, 1998, Messrs. Brondeau and Foster visited the Company's
facilities in Freeport, New York. A tour of the facilities was held, followed
by a meeting between Messrs. Ostrow and Brondeau during which the Company's
valuation and strategic expectations were reviewed. In addition, Mr. Brondeau
and Mr. Ostrow discussed the opportunities for the Company's existing
management team if a business combination occurred.
 
  On October 19, 1998, Messrs. Ostrow and Rosenthal met with Mr. Brondeau and
with Rajiv L. Gupta, Vice Chairman-elect of Parent, and continued discussions
concerning a possible acquisition of the Company by Parent.
 
  On October 21, 1998, the Company and Parent entered into the Confidentiality
Agreement. Thereafter, Parent began its due diligence investigation of the
Company, and the Company furnished to Parent detailed information concerning
the Company's business and future prospects. See Sections 8 and 12.
 
  On November 16 and 17, 1998, meetings were held between representatives of
the Company and Parent, including representatives of Beacon, the Company's
financial advisor, and Deutsche Bank Securities, Parent's financial advisor.
Over the course of the two-day period, the Company's business was discussed in
detail, including its product line, facilities, sales projections and
financial results.
 
  On November 20, 1998, representatives of Beacon and Deutsche Bank Securities
discussed the Company's valuation expectations.
 
                                      20
<PAGE>
 
  On December 3, 1998, Mr. Brondeau indicated in a telephone conversation with
Mr. Ostrow that certain analyses performed by Parent suggested that an
appropriate valuation for the Company was $28 per Share. Mr. Ostrow said that
did not meet the Company's valuation expectations. Between December 3-6,
representatives of Beacon and Deutsche Bank Securities held further
discussions concerning valuation issues.
 
  On December 7, 1998, Parent's Board of Directors authorized Deutsche Bank
Securities to present, on Parent's behalf, a proposal for a potential
acquisition of the Company. The following day, Deutsche Bank Securities
presented a term sheet containing proposed terms for a potential acquisition
by Parent of the Company for $33.50 per Share in cash. Parent's proposal was
conditioned upon receipt of the Tender and Option Agreements from certain
stockholders of the Company and upon the Company's entering into satisfactory
employment agreements with certain key executives and satisfactory amendments
to existing agreements between the Company and the holder of certain minority
interests in two foreign subsidiaries.
 
  On December 10, 1998, Mr. Ostrow and other senior executives of the Company
met in Tokyo with Mr. Brondeau to discuss the terms of the possible
acquisition of the Company, as well as the terms of the Employment Agreements
and the agreements relating to the foreign minority interests.
 
  On December 12, 1998, Parent's counsel furnished drafts of the Merger
Agreement and the Tender and Option Agreement to counsel for the Company.
Thereafter, the parties negotiated the terms of the Merger Agreement, the
Tender and Option Agreement and the Employment Agreements and the agreements
relating to the foreign minority interests.
 
  Between December 14-18, 1998, the terms of the transaction agreements were
negotiated by representatives of Parent and of the Company, including the
amount of the Termination Fee and Expenses (as hereinafter defined) and the
circumstances in which they would be payable, the nature of the restrictions
on the Company's ability to enter into a competing transaction and the
conditions to the Offer.
 
  On December 15, 1998, Mr. Ostrow met with Mr. Gupta. Also present were
representatives of Beacon and Deutsche Bank Securities. At this meeting, Mr.
Gupta indicated that Parent would be willing to increase its offer to $34.00
per Share in cash, subject to the negotiation of satisfactory terms and
conditions in the transaction agreements.
 
  On December 18, 1998, the Company's Board of Directors held a meeting at the
Company's headquarters to consider the proposed transaction.
 
  On December 20, 1998, the Company's Board of Directors met again to consider
the proposed transaction. Beacon delivered its opinion to the effect that the
proposed purchase price of $34.00 per Share in cash in the Offer and the
Merger is fair from a financial point of view to the holders of the Shares. At
the meeting, the Company's Board of Directors unanimously approved the Merger
Agreement and the transactions contemplated thereby, including the Offer and
the Merger, and determined that the Offer and Merger are fair to, and in the
best interests of, the Company's stockholders and recommended that
stockholders accept the Offer and tender their Shares pursuant to the Offer.

  On December 21, 1998, Parent and the Company issued a joint press release
announcing the transactions contemplated by the Merger Agreement.
 
  On December 23, 1998, Purchaser commenced the Offer.
 
  12. PURPOSE OF THE OFFER AND THE MERGER; THE MERGER AGREEMENT AND CERTAIN
OTHER AGREEMENTS.
 
  Purpose of the Offer and the Merger. The purpose of the Offer and the Merger
is to enable Parent to acquire control of, and the entire equity interest in,
the Company. The Offer is being made pursuant to the Merger Agreement and is
intended to increase the likelihood that the Merger will be effected. The
purpose of the Merger is to acquire all of the outstanding Shares not
purchased pursuant to the Offer. Following the Offer, Purchaser and Parent
intend to acquire any remaining equity interest in the Company not acquired in
the Offer by consummating the Merger. Upon consummation of the Merger, the
Company will become a wholly owned subsidiary of Parent.
 
 Merger Agreement.
 
  The following is a summary of certain provisions of the Merger Agreement.
This summary is not a complete description of the terms and conditions of the
Merger Agreement and is qualified in its entirety by reference to the full
text of the Merger Agreement filed with the Commission as an exhibit to the
Tender Offer Statement on Schedule 14D-1 filed by Parent and Purchaser (the
"Schedule 14D-1") and is incorporated herein by reference. Capitalized terms
not otherwise defined below shall have the meanings set forth in the Merger
Agreement. The Merger Agreement may be examined, and copies obtained, as set
forth in Section 8 of this Offer to Purchase.
 
  The Offer. The Merger Agreement provides that the Purchaser will commence
the Offer and that upon the terms and subject to prior satisfaction or waiver
(to the extent permitted to be waived) of the conditions of the Offer, the
Purchaser will purchase all Shares validly tendered pursuant to the Offer. The
Merger Agreement provides that the Purchaser has the right, in its sole
discretion, to modify and make certain changes to the terms and conditions of
the Offer as described in Section 1.
 
  The Company's Board of Directors. The Merger Agreement provides that
immediately upon the acceptance for payment of and payment for any Shares by
Purchaser or any of its affiliates pursuant to the Offer, Purchaser will be
entitled to designate such number of directors, rounded up to the next whole
number, on the Company Board as will give Purchaser, subject to compliance
with Section 14(f) of the Exchange Act, representation on the Company Board
equal to the product of (i) the total number of directors on the Company Board
(giving effect to the increase in the size of the Company Board pursuant to
this paragraph) and (ii) the percentage that the number of votes represented
by Shares beneficially owned by Purchaser and its affiliates (including Shares
so accepted for payment and purchased) bears to the number of votes
represented by Shares then outstanding. In furtherance thereof, concurrently
with such acceptance for payment and payment for such Shares the Company will,
upon request of Parent and compliance with Section 14(f) of the Exchange Act
and Rule 14f-1 promulgated thereunder, use its best efforts promptly either to
increase the size of its the Company Board or to secure the resignations of
such number of its incumbent directors, or both, as is necessary to enable
such designees of Parent to be so elected or appointed to the Company Board,
and the Company will take all actions available to the Company to cause such
designees of Parent to be so elected or appointed. The Merger Agreement
provides that at such time, the Company will, if requested by Parent, also use
its reasonable best efforts to cause persons designated by Parent to
constitute at least the same percentage (rounded up to the next whole number)
as is
 
                                      22
<PAGE>
 
on the Company Board of (i) each committee of the Company Board, (ii) each
board of directors (or similar body) of each subsidiary of the Company and
(iii) each committee (or similar body) of each such board. Notwithstanding the
foregoing, the Company will use its reasonable best efforts to ensure that, in
the event that Purchaser's designees are elected to the Company Board, the
Company Board will have, at all times prior to the Effective Time, at least
three directors who are directors on the date of the Merger Agreement and who
are not officers of the Company, Parent or any of their respective
subsidiaries (the "Independent Directors"); and provided further, that, in
such event, if the number of Independent Directors shall be reduced below
three for any reason whatsoever any remaining Independent Directors (or
Independent Director, if there shall be only one remaining) may designate
persons to fill such vacancies who will be deemed to be Independent Directors
for purposes of the Merger Agreement or, if no Independent Directors then
remain, the other directors may designate three persons to fill such vacancies
who will not be officers or affiliates of the Company, Parent or any of their
respective subsidiaries, and such persons will be deemed to be Independent
Directors for purposes of the Merger Agreement. Subject to applicable law, the
Company will promptly take all action requested by Parent necessary to effect
any such election, including mailing to its shareholders the information
required by Section 14(f) of the Exchange Act and Rule 14(f)-1 promulgated
thereunder (or, at Parent's request, furnishing such information to Parent for
inclusion in the offer documents initially filed with the Commission and
distributed to the stockholders of the Company) as is necessary to enable
Parent's designees to be elected to the Company Board. From and after the
time, if any, that Parent's designees constitute a majority of the Company
Board, any amendment of the Merger Agreement, any termination of the Merger
Agreement by the Company, any extension of time for performance of any of the
obligations of Parent or Purchaser thereunder, any waiver of any condition to
the Company's obligations thereunder or any of the Company's rights thereunder
or other action by the Company thereunder may be effected only by the action
of a majority of the Independent Directors of the Company, which action will
be deemed to constitute the action of any committee specifically designated by
the Company Board to approve the actions contemplated thereby and the full
Company Board; provided, that, if there shall be no Independent Directors,
such actions may be effected by majority vote of the entire Company Board,
except that no such action will amend the terms of the Merger Agreement or
modify the terms of the Offer or the Merger in a manner materially adverse to
the holders of Shares.
 
  The Merger. Pursuant to the Merger Agreement and the NYBCL, as promptly as
practicable after the completion of the Offer and satisfaction or waiver, if
permissible, of all conditions, including the purchase of Shares pursuant to
the Offer and the approval and adoption of the Merger Agreement by the
stockholders of the Company (if required by applicable law), Purchaser will be
merged with and into the Company and the Company will be the Surviving
Corporation and a wholly owned subsidiary of Parent. At the Effective Time,
each Share then outstanding, other than Shares held by (i) the Company or any
of its subsidiaries, (ii) Parent or any of its subsidiaries, including
Purchaser and (iii) stockholders who properly perfect their dissenters' rights
under the NYBCL, will be converted into the right to receive the Merger
Consideration, without interest. Purchaser's Certificate of Incorporation will
become the Certificate of Incorporation of the Surviving Corporation, and
Purchaser's By-laws will be the By-Laws of the Surviving Corporation.
 
  Options. The Merger Agreement provides that prior to the Effective Time, the
Board of Directors of the Company (or, if appropriate, any committee thereof)
will adopt appropriate resolutions and take all other actions necessary to
provide that each outstanding Option granted under the Company's 1990
Nonqualified Stock Option Plan, dated June 1, 1990 (the "1990 Plan") and the
Company's 1996 Long-Term Incentive Plan (the "1996 Plan," and together with
the 1990 Plan, the "Company Stock Option Plans"), whether or not then vested
or exercisable, will, at the Effective Time, be cancelled, and each holder
thereof will be entitled to receive a
 
                                      23
<PAGE>
 
payment in cash from the Company (subject to any applicable withholding taxes,
the "Cash Payment"), upon cancellation, equal to the product of (x) the total
number of Shares subject or related to such Option, whether or not then vested
or exercisable, and (y) the excess, if any, of the Merger Consideration over
the exercise price or purchase price, as the case may be, per Share subject or
related to such Option, each such Cash Payment to be paid to each holder of an
outstanding Option upon cancellation. Notwithstanding the foregoing, if
requested by Purchaser, the Company Board (or, if appropriate, any committee
thereof) will adopt appropriate resolutions providing for such cancellation
and a cash payment equal to 101.8% of the Cash Payment to occur, in respect of
any or all Options held by certain employees of the Company who have entered
into employment agreements with the Company, on the 78th day after the date on
which the Effective Time occurs. The executives that have executed the
Employment Agreements have agreed to receive the payments referred to in the
preceding sentence. If Parent or Purchaser and an Option holder mutually
agree, such Option holder may receive in lieu of such Cash Payment an option
to acquire shares of common stock of Parent on terms providing such Option
holder with value substantially equivalent to the value of such Cash Payment.
In the Merger Agreement, the Company agreed that upon the exercise of any
Option it will issue such Shares as such Option holder may be entitled to
receive upon such exercise and will not exercise any rights it may have under
the Company Stock Option Plans or otherwise to settle such Option with a cash
payment without the written consent of Parent. Subject to the contractual
rights of participants therein, the Company Stock Option Plans and any benefit
plan (or other plan, program or arrangement) providing for the issuance or
grant of any other interest in respect of the capital stock of the Company or
any subsidiary will terminate as of the Effective Time. The Company will take
all steps necessary to ensure that none of the Company or any of its
subsidiaries is or will be bound by any Options, other options, warrants,
rights or agreements which would entitle any person, other than the current
shareholders of Purchaser or its affiliates, to acquire any capital stock of
the Surviving Corporation or any of its subsidiaries or, except as otherwise
provided in this paragraph, to receive any payment in respect thereof and to
cause such Options to be cancelled or cause the holders of the Options to
agree to such cancellation thereof.
 
  Representations and Warranties. In the Merger Agreement, the Company has
made customary representations and warranties to Parent and Purchaser with
respect to, among other things, corporate organization, subsidiaries,
capitalization, authority to enter into the Merger Agreement, the absence of
certain changes, required consents, no conflicts between the Merger Agreement

unimpaired at the Effective Time; and (iii) use its commercially reasonable
efforts to keep in full force and effect insurance and bonds comparable in
amount and scope of coverage to that currently maintained.
 
  Except as set forth in the disclosure schedules to the Merger Agreement, the
Company has agreed that, except as expressly contemplated by the Merger
Agreement or otherwise consented to in writing by Parent, from the date of the
Merger Agreement until the Effective Time, it will not do, and will not permit

making or submission of any Acquisition Proposal (as hereinafter defined), or
enter into or maintain or continue discussions or negotiate with any person or
group in furtherance of such inquiries or to obtain or induce any person or
group to make or submit an Acquisition Proposal or agree to or endorse any
Acquisition Proposal or assist or participate in, facilitate or encourage, any

foregoing or authorize or permit any of its officers, directors or employees
or any of its subsidiaries or affiliates or any investment banker, financial

<PAGE>
 
take any such action; provided, however, that nothing contained in the Merger
Agreement will prohibit the Company Board from, prior to the earlier to occur
of acceptance for payment of Shares pursuant to the Offer or adoption of the
Merger Agreement by the requisite vote of the stockholders of the Company,
furnishing information to or entering into discussions or negotiations with
any person or entity that makes an unsolicited written, bona fide Acquisition
Proposal that constitutes, or may reasonably be expected to lead to, any
Superior Proposal (as hereinafter defined) if, and only to the extent that (i)
the Company Board after consultation with independent legal counsel,
reasonably determines in good faith that the failure to do so would be
reasonably likely to result in a breach of the fiduciary duty of the Company
Board under applicable law and (ii) prior to taking such action the Company
(x) delivers to Parent and Purchaser the notice required pursuant to the
Merger Agreement stating that it is taking such action and (y) receives from
such person or group an executed confidentiality agreement that contains

  Except as expressly permitted by the Merger Agreement, neither the Board of

or fail to make, or propose to withdraw, modify or fail to make its approval
or recommendation of the Offer or the Merger or of the Tender and Option
Agreement and the other Transactions, (ii) approve or recommend, or propose to
approve or recommend, any Acquisition Proposal, (iii) take any action to
render the provisions of any anti-takeover statute, rule or regulation
(including Section 912 of the NYBCL) inapplicable to any person (other than
Parent, Purchaser or their affiliates) or group or to any Acquisition Proposal
or (iv) cause the Company or any of its subsidiaries to accept such
Acquisition Proposal and/or enter into any letter of intent, agreement in
principle, acquisition agreement or other similar agreement (each, an
"Acquisition Agreement") related to any Acquisition Proposal; provided
however, that prior to the earlier to occur of acceptance for payment of
Shares pursuant to the Offer or adoption of the Merger Agreement by the
requisite vote of the stockholders of the Company, the Board of Directors of
the Company may terminate the Merger Agreement if, and only to the extent that
(A) such Acquisition Proposal is a Superior Proposal, (B) the Board of
Directors of the Company, after consultation with independent legal counsel,
reasonably determines in good faith that the failure to do so would be
reasonably likely to result in a breach of the fiduciary duty of the Board of
Directors of the Company under applicable law, (C) the Company will, prior to
or simultaneously with the taking of such action, have paid or pay to Parent
or Purchaser or their designee the Termination Fee and the Expenses, (D) the
Company is not in breach of any provision of the Merger Agreement relating to
the solicitation and negotiation of Acquisition Proposals, (E) the Company
will have complied with its obligations relating to termination of the Merger
Agreement in this situation and (F) concurrently with such termination, the
Company enters into an Acquisition Agreement with respect to such Superior
Proposal.
 
  In addition to the obligations of the Company set forth in the two preceding
paragraphs above, the Company will promptly (and in any event, within 24
hours) advise Parent orally and in writing of any request for information or
the submission or receipt of any Acquisition Proposal, the material terms and
conditions of such Acquisition Proposal, and the identity of the person making
any such Acquisition Proposal. The Company will keep Parent fully informed of
the material developments with respect to any such Acquisition Proposal. The
Company will immediately cease and cause to be terminated any existing
activities, discussions or negotiations with any parties conducted prior to
the Merger Agreement with respect to any of the foregoing.
 
  "Acquisition Proposal" means an inquiry, offer or proposal regarding any of
the following (other than the Transactions contemplated by the Merger
Agreement) involving the Company: (i) any merger, consolidation, share
exchange, recapitalization, liquidation, dissolution, business
 
                                      27
<PAGE>
 
combination or other similar transaction; (ii) any sale, lease, exchange, or
other disposition of 20% or more of the assets of the Company and its
subsidiaries, taken as a whole, or of any Material Business (as hereinafter
defined) or of any subsidiary or subsidiaries responsible for a Material
Business in a single transaction or series of related transactions; (iii) any
tender offer (including a self tender offer) or exchange offer that, if
consummated, would result in any person or group beneficially owning more than
20% of the outstanding shares of any class of equity securities of the
Company; (iv) any acquisition of 20% or more of the outstanding shares of
capital stock of the Company; or (v) any public announcement by the Company or
any third party of a proposal, plan or intention to do any of the foregoing or
any agreement to engage in any of the foregoing. "Superior Proposal" means any
proposal made by a third party to acquire, directly or indirectly, including
pursuant to a tender offer, exchange offer, merger, consolidation, share
exchange, business combination, recapitalization, liquidation, dissolution or
other similar transaction, all the Shares then outstanding or all or
substantially all of the assets of the Company and its subsidiaries which the
Board of Directors of the Company reasonably determines in good faith (after
consultation with its independent financial advisor and after taking into
account any changes to the terms of the Merger Agreement and the Offer that
have been proposed by Parent in response to such proposal) to be more
favorable to the Company and the Company's stockholders. "Material Business"
means any business (or the assets needed to carry out such business) that
contributed or represented 20% or more of the net sales, the net income or the
assets (including equity securities) of the Company and its subsidiaries taken
as a whole.
 
  The Merger Agreement provides that nothing contained therein will prohibit
the Company from taking and disclosing to its stockholders a position
contemplated by Rule 14e-2(a) promulgated under the Exchange Act (dealing with
responses to a tender offer) or from making any disclosure to the Company's
stockholders if the Board of Directors of the Company, after consultation with
independent legal counsel, reasonably determines in good faith that the
failure to take such action would be reasonably likely to result in a breach
of the fiduciary duty of the Board of Directors under applicable law; provided
that neither the Board of Directors of the Company nor any committee thereof
withdraws or modifies, or proposes to withdraw or modify, the approval or
recommendation of the Board of Directors of the Company of the Offer or the
Merger or approves or recommends, or publicly proposes to approve or
recommend, an Acquisition Proposal unless the Company and the Board of
Directors of the Company have complied with all the provisions of the Merger
Agreement relating to the solicitation and negotiation of Acquisition
Proposals.
 
  Indemnification. In the Merger Agreement, Purchaser has agreed that all
rights to indemnification for acts or omissions occurring prior to the
Effective Time existing as of the date of the Merger Agreement in favor of the
current or former directors or officers of the Company and its subsidiaries as
provided in their respective certificates of incorporation or bylaws will
survive the Merger and will continue in full force and effect in accordance
with their terms for a period of six years from the Effective Time. Parent
will cause to be maintained, if available, for a period of six years from the
Effective Time the Company's current directors' and officers' insurance and
indemnification policy (the "D&O Insurance") (provided that Parent may
substitute therefor policies or financial guarantees with the same carriers or
other obligors as insure Parent's directors and officers of at least the same
coverage and amounts containing terms and conditions which are substantially
similar to the existing D&O Insurance) to the extent that such insurance
policies provide coverage for events occurring prior to the Effective Time for
all persons who were directors and officers of the Company on December 20,
1998, so long as the annual premium to be paid by the Company after the date
of the Merger Agreement for such D&O Insurance during such six-year period
would not exceed 200% of the current annual premium therefor. If, during such
six-year period, such insurance coverage
 
                                      28
<PAGE>
 
cannot be obtained at all or can only be obtained for an amount in excess of
200% of the current annual premium therefor, Parent will use all reasonable
efforts to cause to be obtained as much D&O Insurance as can be obtained for
an amount equal to 200% of the current annual premium therefor, on terms and
conditions substantially similar to the existing D&O Insurance.
 
  Employee Plans and Benefits and Agreements. In the Merger Agreement, the
Surviving Corporation agreed, from and after the Effective Time, to honor in
accordance with their terms all existing employment, severance, consulting or
other compensation agreements or benefit contracts between the Company or any
of its subsidiaries and any officer, director or employee of the Company or
any of its subsidiaries, as the same may be modified by the Employment
Agreements, and all benefits or other amounts earned or accrued through the
Effective Time under the benefit plans disclosed in Company's disclosure
schedules to the Merger Agreement.
 
  The Merger Agreement provides that for a period of not less than two years
from the Effective Time, Parent will, or will cause the Surviving Corporation
to, maintain employee benefit plans, programs and arrangements for former
employees of the Company and its subsidiaries who remain employees of the
Surviving Corporation after the Effective Time that are, in the aggregate, no
less favorable than those provided by the Company and any of its subsidiaries
immediately prior to the Effective Time. From and after the Effective Time,
for purposes of determining eligibility and vesting (but not for purposes of
benefit accrual) under any severance, compensation, welfare, pension, or other
benefit plan or arrangement of Parent or any of its subsidiaries which, at the
election of Parent, employees of the Company or any of its subsidiaries become
eligible to participate in, service with the Company or any of its
subsidiaries (whether before or after the Effective Time) will be credited as
if such services had been rendered to Parent or such subsidiary; provided that
Parent and Purchaser shall have no obligation to (i) employ any individual,
(ii) include any individual in any stock option or other equity based
compensation or benefit plan or arrangement or (iii) include any such
employees of the Company and its subsidiaries in any benefit plan of Parent or
its subsidiaries.
 
  Reasonable Best Efforts. In the Merger Agreement, subject to the terms and
conditions thereof, each of the parties has agreed to use its reasonable best
efforts to take, or cause to be taken, all appropriate action, and to do, or
cause to be done, all things necessary, proper or advisable under applicable
laws and regulations to consummate and make effective as soon as reasonably
practicable the Transactions. In the case that at any time after the Effective
Time any further action is necessary or desirable to carry out the purposes of
the Merger Agreement, the proper officers and directors of each party to the
Merger Agreement will take all such necessary action. such reasonable best
efforts include (i) the obtaining of all necessary consents, approvals or
waivers from third parties and governmental authorities necessary to the
consummation of the Transactions and (ii) opposing vigorously any litigation
or administrative proceeding relating to the Merger Agreement or the
Transactions, including promptly appealing any adverse court or agency order.
Notwithstanding the foregoing or any other provisions contained in the Merger
Agreement to the contrary, neither Parent or the Company nor any of their
respective affiliates will be under any obligation of any kind to (i) litigate
against any federal, state or local government or any court, administrator or
regulatory agency or commission or other governmental authority or agency,
domestic or foreign (a "Governmental Entity"), including but not limited to
any governmental or regulatory authority with jurisdiction over the
enforcement of any applicable federal, state, local and foreign antitrust,
competition or other similar laws or (ii) otherwise agree with any
Governmental Entity or any other party to sell or otherwise dispose of, agree
to any material limitations on the ownership or control of, or hold separate
(through the establishment of a trust or otherwise) a material portion of the
assets or businesses of any of the Company, its subsidiaries, Parent or any of
Parent's affiliates.
 
  Pursuant to the Merger Agreement, the Company and its Board of Directors
will (i) take all action necessary to ensure that no state takeover statute or
similar statute or regulation is or
 
                                      29
<PAGE>
 
becomes applicable to the Offer, the Merger, the Merger Agreement, the Tender
and Option Agreement or any of the other Transactions and (ii) if any state
takeover statute or similar statute or regulation becomes applicable to the
Transactions take all action necessary to ensure that the Transactions may be
consummated as promptly as practicable on the terms contemplated by the Merger
Agreement and the Tender and Option Agreement and otherwise to minimize the
effect of such statute or regulation on the Transactions.
 
  Standstill Agreements. DURING THE PERIOD FROM THE DATE OF THE MERGER
AGREEMENT THROUGH THE EFFECTIVE TIME, THE MERGER AGREEMENT PROVIDES THAT THE
COMPANY WILL NOT TERMINATE, AMEND, MODIFY OR WAIVE ANY PROVISION OF ANY
CONFIDENTIALITY OR STANDSTILL OR SIMILAR AGREEMENT TO WHICH THE COMPANY OR ANY
OR ITS SUBSIDIARIES IS A PARTY (OTHER THAN ANY INVOLVING PARENT). SUBJECT TO
THE FOREGOING, DURING SUCH PERIOD, THE COMPANY HAS AGREED TO ENFORCE, TO THE
FULLEST EXTENT PERMITTED UNDER APPLICABLE LAW, THE PROVISIONS OF ANY SUCH
AGREEMENTS, INCLUDING OBTAINING INJUNCTIONS TO PREVENT ANY BREACHES OF SUCH
AGREEMENTS AND TO ENFORCE SPECIFICALLY THE TERMS AND PROVISIONS THEREOF IN ANY
COURT OR OTHER TRIBUNAL HAVING JURISDICTION.
 
  Stockholder Meeting. The Merger Agreement provides that to the extent
required by applicable law, the Company will promptly take all action
necessary in accordance with the NYBCL and its Certificate of Incorporation
and Bylaws to convene a meeting of the stockholders of the Company to consider
and vote on the Merger and the Merger Agreement. At such stockholder meeting,
all of the Shares then owned by Parent, Purchaser or any other subsidiary of
Parent will be voted to approve the Merger and the Merger Agreement. The Board
of Directors of the Company will recommend that the Company's stockholders
vote to approve the Merger and the Merger Agreement if such vote is sought,
will use its best efforts to solicit from shareholders of the Company proxies
in favor of the Merger and will take all other action in its judgment
necessary and appropriate to secure the vote of stockholders required by the
NYBCL to effect the Merger.
 
  Notwithstanding the foregoing, in the event that Purchaser acquires at least
90% of the then outstanding Shares, at the request of Purchaser, the parties
to the Merger Agreement will take all necessary and appropriate action to
effect the Merger as a "short-form" merger. See Section 13.
 
  The Merger Agreement also provides that in the event that Purchaser reduces
the Minimum Condition as described in Section 1 and accepts for payment the
Shares tendered pursuant to the Offer, which Shares are less than two-thirds
of the Fully Diluted Shares, the Company will convene a meeting of its
stockholders, or take or permit Purchaser to take such action as may be
necessary or desirable, to amend the Certificate of Incorporation to provide
that the requisite vote of the Company's stockholders on any merger or
consolidation (including the Merger) will be a majority of the Shares
outstanding. At such meeting, all of the Shares then owned by Parent,
Purchaser or any other subsidiary of Parent shall be voted to approve such
amendment.
 
  Conditions to the Merger. The respective obligations of each party to effect
the Merger are subject to the satisfaction or waiver, where permissible, prior
to the Effective Time, of the following conditions: (i) if required by the
NYBCL, the Merger Agreement shall have been approved by the affirmative vote
of the stockholders of the Company by the requisite vote in accordance with
applicable law; (ii) no statute, rule, regulation, executive order, decree or
injunction shall have been enacted, entered, promulgated, or enforced by any
court or Governmental Entity which is in effect and has the effect of
prohibiting the consummation of the Merger; and (iii) the waiting period (and
any extension thereof) applicable to the consummation of the Merger under the
HSR Act, if any, shall have expired or been terminated.
 
  The obligations of Parent and Purchaser to effect the Merger are further
subject to the satisfaction or waiver, prior to the Effective Time, of the
conditions that Purchaser shall have
 
                                      30
<PAGE>
 
accepted for payment and paid for Shares tendered pursuant to the Offer;
provided, however, that neither Parent nor Purchaser will be entitled to
assert the failure of this condition if the failure of such condition results
from a breach by Parent or Purchaser of any of their obligations under the
Merger Agreement.
 
  The obligation of the Company to effect the Merger is further subject to the
satisfaction or waiver, prior to the Effective Time, of the conditions that
Purchaser shall have accepted for payment and paid for Shares tendered
pursuant to the Offer; provided, however, that the Company will not be
entitled to assert the failure of this condition if the failure of such
condition results from a breach by the Company of any of its obligations under
the Merger Agreement.
 
  Termination. The Merger Agreement may be terminated and the Merger
contemplated thereby may be abandoned at any time (notwithstanding approval
thereof by the shareholders of the Company) prior to the Effective Time:
 
    (i) by mutual written consent duly authorized by the Boards of Directors
  of the Company, Parent and Purchaser;
 
    (ii) by Parent, Purchaser or the Company if any court of competent
  jurisdiction or other Governmental Entity shall have issued a final order,
  decree or ruling or taken any other final action restraining, enjoining or
  otherwise prohibiting the consummation of the Offer or the Merger and such
  order, decree or ruling or other action is or shall have become
  nonappealable;
 
    (iii) by Parent or Purchaser if due to an occurrence or circumstance
  which would result in the occurrence and continued existence of any of the
  conditions to the Offer, Purchaser shall have (A) failed to commence the
  Offer within the time required by Regulation 14D under the Exchange Act,
  (B) terminated the Offer without purchasing any Shares pursuant to the
  Offer or (C) failed to accept for payment Shares pursuant to the Offer
  prior to April 30, 1999; provided, however, that the right to terminate the
  Merger Agreement under this provision will not be available to Parent or
  Purchaser if the occurrence and continued existence of any of the
  conditions to the Offer results from the breach by Parent or Purchaser of
  any of their respective obligations under the Merger Agreement;
 
    (iv) by the Company (A) if Purchaser shall have (1) failed to commence
  the Offer within the time required by Regulation 14D under the Exchange
  Act, (2) terminated the Offer without purchasing any Shares pursuant to the
  Offer or (3) failed to accept for payment Shares pursuant to the Offer
  prior to April 30, 1999; provided, however, that the right to terminate the
  Merger Agreement under this provision will not be available to the Company
  if such failure results from the breach by the Company of any of its
  obligations under the Merger Agreement or if there shall have occurred any
  of the events described in paragraph (g) in Section 15 and the right to
  terminate this Agreement under this provision also will not be available to
  the Company prior to April 30, 1999 if there shall have occurred any of the
  events set forth in paragraph (i) of Section 15 or (B) prior to the
  purchase of Shares pursuant to the Offer, concurrently with the execution
  of an Acquisition Agreement under the circumstances permitted by the
  provisions of the Merger Agreement relating to the solicitation and
  negotiation of Acquisition Proposals, provided that such termination under
  this clause (B) will not be effective unless (x) the Company and its Board
  of Directors shall have also complied with all their obligations under the
  provisions relating to solicitation of Acquisition Proposals and shall have
  paid the Termination Fee and the Expenses and (y) the Company provides
  Purchaser with at least five business days' prior written notice prior to
  terminating the Merger Agreement, which notice will be accompanied by (1) a
  copy of the
 
                                      31
<PAGE>
 
  proposed Acquisition Agreement with respect to the Superior Proposal that
  the Company proposes to accept and (2) the Company's written certification
  that it has made the determinations with respect to such Superior Proposal
  required pursuant to the Merger Agreement and representation that the
  Company will, in the absence of any other superior Acquisition Proposal,
  execute such Acquisition Agreement unless Parent or Purchaser modify the
  Offer or the Merger Agreement such that the Company's Board of Directors
  reasonably believes in good faith after consultation with its independent
  legal counsel and financial advisors that the Offer and the Merger (as so
  modified) are at least as favorable as such Superior Proposal; or
 
    (v) by the Company prior to the purchase of Shares pursuant to the Offer
  if (A) there shall have been a material breach of any representation or
  warranty in the Merger Agreement on the part of Parent or Purchaser which
  materially adversely affects (or materially delays) the consummation of the
  Offer or (B) Parent or Purchaser shall not have performed or complied with,
  in all material respects (without reference to any materiality
  qualifications therein), each covenant or agreement contained in the Merger
  Agreement and required to be performed or complied with by them, and such
  breach materially adversely affects (or materially delays) the consummation
  of the Offer, and which breach, in the case of clause (A) and clause (B)
  above, shall not have been cured prior to the earlier of 10 days following
  notice of such breach and two business days prior to the Expiration Date;
  provided, however, that Parent and Purchaser will have no right to cure
  such breach and the Company may immediately terminate the Merger Agreement
  in the event that such breach by Parent or Purchaser was willful or
  intentional.
 
  In the event of the termination and abandonment of the Merger Agreement
pursuant to the above provisions, the Merger Agreement, except for certain
enumerated provisions, will become void and have no effect, without any
liability on the part of any party or its affiliates, directors, officers or
stockholders. Nothing in this provision will relieve any party to the Merger
Agreement of liability for breach of the Merger Agreement.
 
  Termination Fee. Except as provided in the following paragraph below, the
Merger Agreement provides that all fees and expenses incurred by the parties
to the Merger Agreement will be borne solely and entirely by the party which
has incurred such fees and expenses.
 
  If:
 
    (i) Parent or Purchaser terminate the Merger Agreement pursuant to
  paragraph (iii) under "--Termination" above (in circumstances other than
  those described in paragraph (ii) below) or the Company terminates the
  Merger Agreement pursuant to paragraph (iv)(A) under "--Termination" above,
  in either case, in circumstances when, prior to such termination any third
  party shall have acquired beneficial ownership of 20% or more of the
  outstanding Shares or shall have consummated an Acquisition Proposal (or
  with respect to any proposal that may be existing on December 20, 1998 and
  which becomes publicly known prior to such termination, not withdrawn such
  Acquisition Proposal) or such third party has publicly made or announced an
  intention to make or consummate an Acquisition Proposal (or the making of
  such Acquisition Proposal or such intention has otherwise become publicly
  known), and, in any such case, within 12 months of such termination
  thereafter (x) the Company or any of its subsidiaries enters into an
  Acquisition Agreement with respect to an Acquisition Proposal with such
  party, or (y) such party or any other party otherwise consummates an
  Acquisition Proposal;
 
    (ii) Parent or Purchaser terminates the Merger Agreement pursuant to
  paragraph (iii) under "--Termination" above and (x) the Company shall have
  willfully and intentionally breached its obligations under the provisions
  described under "--No Solicitation" above, or (y) there shall have occurred
  any of the events set forth in paragraph (g) of Section 15 of this Offer to
  Purchase; or
 
                                      32
<PAGE>
 
    (iii) the Company terminates the Merger Agreement pursuant to paragraph
  (iv)(B) under "--Termination."
 
then, in each case, the Company (A) will pay to Parent, within one business
day following the execution and delivery of such agreement or such occurrence,
as the case may be, or simultaneously with such termination pursuant to clause
(iv)(B) under "--Termination," a fee, in cash, of $11 million (the
"Termination Fee"); provided, that the Company in no event will be obligated
to pay more than one such Termination Fee with respect to all such agreements
and occurrences and such termination and (B) will reimburse Parent and
Purchaser for all their out-of-pocket fees and expenses actually incurred by
Parent, Purchaser or their respective affiliates in connection with the Merger
Agreement, the Offer, the Merger, the Tender and Option Agreement and the
other transactions contemplated by the Merger Agreement, including all fees
and expenses of counsel, accountants, investment bankers, experts and
consultants to each of Parent or Purchaser and their respective affiliates and
the expenses of the preparation, printing, filing and mailing of the Offer
Documents, such fees and expenses not to exceed $2 million (the "Expenses").
Any payment required to be made pursuant to this paragraph will be made to
Parent by wire transfer of immediately available funds to an account
designated by Parent. These provisions will not derogate from any other rights
or remedies which Parent or Purchaser may possess under the Merger Agreement
or under applicable law.
 
 Tender and Option Agreement.
 
  The following is a summary of certain provisions of the Tender and Option
Agreement. This summary is not a complete description of the terms and
conditions of the Tender and Option Agreement and is qualified in its entirety
by reference to the full text of the Tender and Option Agreement filed with
the Commission as an exhibit to the Schedule 14D-1 and is incorporated herein
by reference. Capitalized terms not otherwise defined below shall have the
meanings set forth in the Tender and Option Agreement. The Tender and Option
Agreement may be examined, and copies obtained, as set forth in Section 8 of
this Offer to Purchase.
 
  Pursuant to the Tender and Option Agreement, each Certain Stockholder agreed
to validly tender (or cause the record owner of such shares to validly tender)
and sell (and not withdraw, except in the event the Purchase Option (as
hereinafter defined) is exercised, in which case such withdrawal will be for
the limited purpose of consummating the Purchase Option) pursuant to and in
accordance with the terms of the Offer not later than the fifth business day
after commencement of the Offer (or the earlier of the Expiration Date and the
fifth business day after such Shares are acquired by such Certain Stockholder
if the Certain Stockholder acquires Shares after the date hereof), or, if the
Certain Stockholder has not received this Offer to Purchase and the related
Letter of Transmittal by such time, within two business days following receipt
of such documents, all of the then outstanding Shares beneficially owned by
such Certain Stockholder.
 
  Each Certain Stockholder (other than Mr. Ronald Ostrow's three children)
agreed (a) to appear (or not appear, if requested by Parent or Purchaser) at
any annual, special, postponed or adjourned meeting of the stockholders of the
Company or otherwise cause the Shares such Certain Stockholder beneficially
owns to be counted as present (or absent, if requested by Parent or Purchaser)
thereat for purposes of establishing a quorum and to vote or consent, and (b)
to constitute and appoint Parent and Purchaser, or any nominee thereof, with
full power of substitution, during and for the term of the Tender and Option
Agreement, as his true and lawful attorney and proxy for and in his name,
place and stead, to vote all the Shares such Certain Stockholder beneficially
owns at the time of such vote, at any annual, special, postponed or adjourned
meeting of the stockholders of the Company (and this appointment will include
the right to sign his name (as stockholder) to any consent, certificate or
other
 
                                      33
<PAGE>
 
document relating to the Company that laws of the State of New York may
require or permit), in the case of both (a) and (b) above, (x) in favor of
approval and adoption of the Merger Agreement and approval and adoption of the
Merger and the other transactions contemplated thereby and (y) against (1) any
Acquisition Proposal, (2) any action or agreement that would result in a
breach in any respect of any covenant, agreement, representation or warranty
of the Company under the Merger Agreement and (3) the following actions (other
than the Merger and the other transactions contemplated by the Merger
Agreement): (i) any extraordinary corporate transaction, such as a merger,
consolidation or other business combination involving the Company or any of
its subsidiaries; (ii) a sale, lease or transfer of a material amount of
assets of the Company or any of its subsidiaries, or a reorganization,
recapitalization, dissolution or liquidation of the Company or any of its
subsidiaries; (iii) (A) any change in a majority of the persons who constitute
the Board of Directors of the Company or any of its subsidiaries as of the
date hereof; (B) any change in the present capitalization of the Company or
any amendment of the Company's or any of its subsidiaries' certificate of
incorporation or bylaws, as amended to date; (C) any other material change in
the Company's or any of its subsidiaries' corporate structure or business; or
(D) any other action that is intended, or could reasonably be expected, to
impede, interfere with, delay, postpone, or adversely affect the Offer, the
Merger and the other transactions contemplated by the Tender and Option
Agreement and the Merger Agreement.
 
  Each Certain Stockholder granted to Parent and Purchaser an irrevocable
option (the "Purchase Option") to purchase for cash, in a manner set forth
below, any or all of the Shares (and including Shares acquired after the date
hereof by such Certain Stockholder) beneficially owned by the Certain
Stockholder at a price (the "Exercise Price") per Share equal to $34.00. In
the event of any stock dividends, stock splits, recapitalizations,
combinations, exchanges of shares or the like, the Exercise Price will be
appropriately adjusted for this purpose.
 
  The Tender and Option Agreement provides that subject to the conditions set
forth below, the Purchase Option may be exercised by Parent or Purchaser, in
whole or in part, at any time or from time to time after the occurrence of any
Trigger Event (as defined below). A "Trigger Event" means any one of the
following: (i) the Merger Agreement becomes terminable under circumstances
that entitle Parent or Purchaser to receive the Termination Fee or the
Expenses under the Merger Agreement (regardless of whether the Merger
Agreement is actually terminated and whether such Termination Fee or Expenses
are then actually paid), (ii) the Offer is consummated but, due to the failure
of the Certain Stockholder to validly tender and not withdraw all of the then
outstanding Shares beneficially owned by such Certain Stockholder, the
Purchaser has not accepted for payment or paid for all of such Shares, (iii) a
tender or exchange offer for at least 20% of the Shares shall have been
publicly proposed to be made or shall have been made by another person, or
(iv) it shall have been publicly disclosed or Parent or Purchaser shall have
otherwise learned that (A) any person or "group" (as defined in Section
13(d)(3) of the Exchange Act) (other than Parent or Purchaser) shall have
acquired or proposed to acquire beneficial ownership of more than 20% of any
class or series of capital stock of the Company (including Shares), through
the acquisition of stock, the formation of a group or otherwise, or shall have
been granted any option, right or warrant, conditional or otherwise, to
acquire beneficial ownership of more than 20% of any class or series of
capital stock of the Company or any of its subsidiaries, or (B) any person or
group (other than Parent and Purchaser) shall have entered into or publicly
offered to enter into a definitive agreement or an agreement in principle with
respect to a merger, consolidation or other business combination with the
Company or any of its subsidiaries.
 
  Pursuant to the Tender and Option Agreement, if requested by Parent and
Purchaser in the Exercise Notice, such Certain Stockholder will exercise all
Options (to the extent exercisable)
 
                                      34
<PAGE>
 
and other rights (including conversion or exchange rights) beneficially owned
by such Certain Stockholder and will sell or, if directed by Parent and
Purchaser, tender the Shares acquired pursuant to such exercise to Parent or
Purchaser as provided in the Tender and Option Agreement.
 
  The Purchase Option will terminate (a) as it relates to a Certain
Stockholder, upon purchase by Parent or Purchaser of the Shares owned by such
Certain Stockholder pursuant to the Offer or (b) upon the earliest of: (i) the
Effective Time; (ii) termination of the Merger Agreement other than upon,
during the continuance of or after a Trigger Event; or (iii) 90 days following
any termination of the Merger Agreement upon, during the continuance of or
after a Trigger Event (or if, at the expiration of such 90 day period the
Purchase Option cannot be exercised by reason of any applicable judgment,
decree, order, injunction, law or regulation, 10 business days after such
impediment to exercise has been removed or has become final and not subject to
appeal).
 
  The Tender and Option Agreement provides that in the event (i) Parent or
Purchaser exercises the Purchase Option and purchases Shares representing at
least 20% of the then outstanding Shares on a fully diluted basis (the
"Purchase Event"), (ii) no Acquisition Proposal shall have been consummated
and (iii) the Merger Agreement shall have terminated and the Company shall not
have been in material breach of the Merger Agreement at the time of such
termination, upon the written request of the Company made within five business
days after the Purchase Event, Parent will cause Purchaser or another
subsidiary of Parent to commence, as soon as reasonably practicable, a tender
offer for all Shares at a cash price equal to the Exercise Price, on terms and
subject to conditions substantially similar to those contained in the Merger
Agreement.
 
  The Tender and Option Agreement provides that if, within twelve months
following the exercise of the Purchase Option by Parent or Purchaser, Parent
or Purchaser sells any or all of the Shares acquired upon exercise of the
Purchase Option to an unaffiliated third party (a "Subsequent Sale") at a per
Share price in excess of the Exercise Price (the "Subsequent Sale Price"),
then Parent or Purchaser will pay to each Certain Stockholder, within five
days of receipt of payment by Parent or Purchaser, an amount equal to such
Certain Stockholder's pro rata share of 50% of the excess of the Subsequent
Sale Price over the Exercise Price multiplied by the number of shares sold in
the Subsequent Sale.
 
  In the Tender and Option Agreement, the obligation of each Certain
Stockholder to sell such Certain Stockholder's Shares to Parent or Purchaser
hereunder is subject to the conditions that (i) all waiting periods, if any,
under the HSR Act, applicable to the sale of the Shares or the acquisition of
the Shares by Parent or Purchaser, as the case may be, hereunder have expired
or have been terminated; (ii) all consents, approvals, orders or
authorizations of, or registrations, declarations or filings with, any court,
administrative agency or other Governmental Entity, if any, required in
connection with sale of the Shares or the acquisition of the Shares by Parent
or Purchaser hereunder have been obtained or made; and (iii) no preliminary or
permanent injunction or other order by any court of competent jurisdiction
prohibiting or otherwise restraining such sale or acquisition is in effect.
 
  Under the Tender and Option Agreement, the Company has agreed to provide
Parent and Purchaser certain registration rights with respect to the Shares
purchased pursuant to the Purchase Option.
 
                                      35
<PAGE>
 
  The Tender and Option Agreement will terminate (a) as to any Certain
Stockholder upon the purchase of all the Shares beneficially owned by such
Certain Stockholder pursuant to the Offer, (b) except as specifically provided
for in certain sections of the Tender and Option Agreement relating to the
Puchase Option, which will only terminate as and when provided therein, on the
earlier to occur of (i) the Effective Time or (ii) the date the Merger
Agreement is terminated in accordance with its terms, or (c) by the mutual
consent of each Certain Stockholder as to its rights and obligations
hereunder, the Board of Directors of the Company and the Board of Directors of
Parent.
 
 Confidentiality Agreement.
 
  The following is a summary of certain provisions of the Confidentiality
Agreement entered into on October 21, 1998 by Parent and the Company (the
"Confidentiality Agreement"). This summary is not a complete description of
the terms and conditions of the Confidentiality Agreement and is qualified in
its entirety by reference to the full text of the Confidentiality Agreement
filed with the Commission as an exhibit to the Schedule 14D-1 and is
incorporated herein by reference. Capitalized terms not otherwise defined
below have the meanings set forth in the Confidentiality Agreement. The
Confidentiality Agreement may be examined, and copies obtained, as set forth
in Section 8 of this Offer to Purchase.
 
  Pursuant to the terms of the Confidentiality Agreement that Parent and
Purchaser entered into on October 21, 1998, the Company and Parent agreed to
provide, among other things, for the confidential treatment of their
discussions regarding the Offer and the Merger and the exchange of certain
confidential information concerning the Company. In addition, each party
agreed to certain standstill provisions which terminated upon the execution of
the Merger Agreement. The Company also agreed for a limited period to enter
into exclusive discussions with Parent regarding a possible transaction,
terminable by the Company upon two business days' notice.
 
 Employment Agreements.
 
  The following is a summary of certain provisions of the employment
agreements entered into by nine executives of the Company, including Ronald D.
Ostrow, President, Chief Executive Officer and Director, Richard Kessler,
Executive Vice President, Chief Operating Officer and Director, David
Rosenthal, Vice President-Finance and Treasurer, and six other employees of
the Company, which will become effective upon the earlier of the consummation
of the Offer or the Merger (the "Employment Agreements"). This summary is not
a complete description of the terms and conditions of the Employment
Agreements and is qualified in its entirety by reference to the full text of
the Employment Agreements filed with the Commission as an exhibit to the
Tender Offer Statement on Schedule 14D-1 filed by Parent and Purchaser (the
"Schedule 14D-1") and is incorporated herein by reference. Capitalized terms
not otherwise defined below shall have the meanings set forth in the
Employment Agreements. The Employment Agreements may be examined, and copies
obtained, as set forth in Section 8 of this Offer to Purchase.
 
  In connection with the negotiation of the Merger Agreement, Parent requested
that certain executives of the Company amend their existing employment
agreements with the Company, including elimination of certain benefits
potentially available to such executives as a result of a change in control
(such as the consummation of the Offer or Merger), and an extension of the
term of the Employment Agreement. The Employment Agreements are for a fixed
term of three years. The individual's duties under the Employment Agreements
are substantially the same as his pre-Merger duties as those duties may
evolve, in a manner consistent with the position held by the individual, over
time and are to generally be performed at the Company's current headquarters
or within 25 miles thereof.
 
  The compensation, including the opportunity to earn performance based
bonuses, benefits and perquisites payable under the Employment Agreements are
equal to those in effect at the date of the Merger Agreement, subject to
increase at the Company's option over the term of the
 
                                      36
<PAGE>
 
Employment Agreements. In addition, to induce the executives to remain in the
employ of the Company and as additional compensation for critical services to
be rendered during the difficult period of integration and transition after
the Merger, each executive will be entitled on the first anniversary of the
effective date of the Employment Agreement to an amount equal to 60% of his
annual compensation, provided he is employed by the Company as of such date,
or if the executive is terminated without Cause or with Good Reason (both as
defined) prior to such time, a ratable portion of such payment.
 
  The executives also agreed to a defined cash payout in cancellation of
Options (whether or not such Options are exercisable) they own. See "--Merger
Agreement--Options" above.
 
  Under the Employment Agreements, the employment relationship can be
terminated by either the individual or the Company during the term of the
contracts. If an individual is terminated for Cause, or by the individual's
own volition, the only payments due are compensation and benefits earned
through the date of termination. If an individual is terminated by the Company
without Cause, or by the individual for Good Reason, the individual is
entitled to receive the agreed compensation and benefits through the then
remaining term of the Employment Agreement.
 
  The Employment Agreements contain confidentiality provisions with respect to
proprietary information, and prohibit competition with the Company for a
period of 18 months (12 if the individual is terminated without Cause)
following termination of employment.
 
  Other Agreements. In connection with the negotiation of the Merger
Agreement, Parent requested that the Company enter into amendments to existing
shareholder agreements between the Company and one of its employees with
respect to certain minority shareholdings in the Company's Swiss and Asian
subsidiaries. Such amendments, which will become effective upon the
consummation of the Merger, provide the Company with the right to repurchase
such minority interests at any time and also clarify the existing terms of the
formula purchase price for the minority interests.
 
  13. PLANS FOR THE COMPANY; OTHER MATTERS.
 
  Plans for the Company. Parent intends to combine the operations of the
Company with the printed wiring board business of Parent's Shipley division to
create a new Shipley Ronal division which will be part of Parent's Electronic
Materials business group. Parent intends to reduce costs by leveraging common
assets, operations, sales and technical organizations. Parent will continue to
evaluate and review the Company and its business, assets, corporate structure,
capitalization, operations, properties, policies, management and personnel
with a view towards determining how to optimally realize any potential
benefits which arise from the combination of the operations of the Company
with those of Parent. Such evaluation and review is ongoing and is not
expected to be completed until after the consummation of the Offer and the
Merger. If, as and to the extent that Purchaser acquires control of the
Company, Parent and Purchaser will complete such evaluation and review of the
Company and will determine what, if any, changes would be desirable in light
of the circumstances which then exist. Such changes could include, among other
things, changes in the Company's business, corporate structure, certificate of
incorporation, by-laws, capitalization or management or involve consolidating
and streamlining certain operations and reorganizing other businesses and
operations. In addition, subject to the terms of the Merger Agreement, Parent
currently intends to terminate the declaration of the Company's regular
quarterly dividend after the consummation of the Offer.
 
  Assuming the Minimum Condition is satisfied and Purchaser purchases Shares
pursuant to the Offer, Parent intends to promptly exercise its rights under
the Merger Agreement to obtain majority representation on, and control of, the
Company Board. See Section 12. Purchaser
 
                                      37
<PAGE>
 
presently intends to exercise its rights to cause the Company to elect to the
Company Board its designees, and Purchaser intends to select such designees
from among the individuals (who are currently officers or directors of Parent)
identified in Schedule I hereto and in the Schedule 14D-9. The Merger
Agreement also provides that the directors of Purchaser immediately prior to
the Effective Time shall be the directors of the Surviving Corporation at and
after the Effective Time. Purchaser or an affiliate of Purchaser may,
following the consummation or termination of the Offer, seek to acquire
additional Shares through open market purchases, privately negotiated
transactions, a tender offer or exchange offer or otherwise, upon such terms
and at such prices as it shall determine, which may be more or less than the
Offer Price. Purchaser and its affiliates also reserve the right to dispose of
any or all Shares acquired by them, subject to the terms of the Merger
Agreement.
 
  Except as disclosed in this Offer to Purchase, and except as may be effected
in connection with the integration of operations referred to above, neither
Parent nor Purchaser has any present plans or proposals that would result in
an extraordinary corporate transaction, such as a merger, reorganization,
liquidation, or sale or transfer of a material amount of assets, involving the
Company or any of its subsidiaries, or any material changes in the Company's
capitalization, corporate structure, business or composition of its management
or the Company Board.
 
  Stockholder Approval. Under the NYBCL and the Company's Certificate of
Incorporation, the approval of the Company Board and the affirmative vote of
the holders of two-thirds of the outstanding Shares are required to adopt and
approve the Merger Agreement and the Merger. The Company has represented in
the Merger Agreement that the execution and delivery of the Merger Agreement
by the Company and the consummation by the Company of the transactions
contemplated by the Merger Agreement have been duly authorized by all
necessary corporate action on the part of the Company, subject to the approval
of the Merger and the Merger Agreement by the Company's stockholders in
accordance with the NYBCL. In addition, the Company has represented that the
affirmative vote of the holders of two-thirds of the outstanding Shares is the
only vote of the holders of any class or series of the Company's capital stock
which is necessary to approve the Merger Agreement and the transactions
contemplated thereby, including the Merger. Therefore, unless the Merger is
consummated pursuant to the short-form merger provisions under the NYBCL
described below (in which case no further corporate action by the stockholders
of the Company will be required to complete the Merger), the only remaining
required corporate action of the Company will be the approval of the Merger
Agreement and the Merger by the affirmative vote of the holders of two-thirds
of the outstanding Shares. The Merger Agreement provides that Parent will
vote, or cause to be voted, all of the Shares then owned by Parent, Purchaser
or any of Parent's other subsidiaries and affiliates in favor of the approval
of the Merger and the adoption of the Merger Agreement. In the event that
Parent, Purchaser and Parent's other subsidiaries acquire in the aggregate at
least two-thirds of the Shares entitled to vote on the approval of the Merger
and the Merger Agreement, they would have the ability to effect the Merger
without the affirmative votes of any other stockholders. The Merger Agreement
also provides that, in the event Purchaser reduces the Minimum Condition as
described in Section 1 and purchases less than two-thirds of the Fully Diluted
Shares, the Company will hold a meeting of its stockholders to amend the
Certificate of Incorporation to provide that the requisite vote of the
Company's stockholders on any merger or consolidation (including the Merger)
will be a majority of the Shares outstanding. Parent and Purchaser have agreed
to vote any Shares owned by them in favor of such amendment at any such
meeting.

  Short-Form Merger. Section 905 of the NYBCL provides that, if a corporation
owns at least 90% of the outstanding shares of each class of another
corporation, the corporation holding such stock may either merge such other
corporation into itself or merge itself into such other corporation, in either
case, without any action or vote on the part of the board of directors or the
stockholders of such other corporation (a "short-form merger"). In the event
that Parent, Purchaser and any other subsidiaries of Parent acquire in the
aggregate at least 90% of the outstanding Shares, pursuant to the Offer or
otherwise, then, at the election of Parent, a short-form merger could be
effected without any approval of the Company Board or the stockholders of the
Company, subject to compliance with the provisions of Section 905 of the
NYBCL. In the Merger Agreement, Parent, Purchaser and the Company have agreed
that, notwithstanding that all conditions to the Offer are satisfied or waived
as of the scheduled Expiration Date, Purchaser may extend the Offer on one
occasion for a period not to exceed 10 business days, if the Minimum Condition
has been satisfied but less than 90% of the Fully Diluted Shares have been
validly tendered and not properly withdrawn. Even if Parent and Purchaser do
not own 90% of the outstanding Shares following consummation of the Offer,
Parent and Purchaser could seek to purchase additional shares in the open
market or otherwise in order to reach the 90% threshold and employ a short-
form merger. The per Share consideration paid for any Shares so acquired may
be greater or less than that paid in the Offer. Parent presently intends to
effect a short-form merger if permitted to do so under the NYBCL.
 
  Appraisal Rights. Holders of Shares do not have appraisal rights as a result
of the Offer. However, if the Merger is consummated, holders of Shares at the
record date for determining stockholders entitled to vote on the Merger will
have certain rights pursuant to the provisions of Section 623 and 910 of the
NYBCL ("Sections 623 and 910") to dissent and demand appraisal of their Shares
unless the Listing Exception (as hereinafter defined) is applicable. In
addition, if the Merger is accomplished without a vote of the Company's
stockholders, such as a short-form merger (see the immediately preceding
paragraph), the minority stockholders will have certain rights to dissent and
demand appraisal of their Shares. Under Sections 623 and 910, stockholders who
have the right to dissent in either of the two situations described above, and
who comply with the applicable statutory procedures, will be entitled to
receive a judicial determination of the fair value of their Shares (exclusive
of any element of value arising from the accomplishment or expectation of the
proposed Merger) and to receive payment of such fair value in cash, together
with a fair rate of interest, if any. Any such judicial determination of the
fair value of Shares could be based upon factors other than, or in addition
to, the price per Share to be paid in the Merger or the market value of the
Shares. The value so determined could be more or less than the price per Share
to be paid in the Merger. If the Merger is accomplished with a vote of the
Company's stockholders, minority stockholders will not have the right to
dissent and demand appraisal of their Shares, if on the record date for
determining stockholders entitled to vote on the Merger the Shares remain
listed on the NYSE or another national securities exchange or are designated
as a national market system security on an interdealer quotation system by the
National Association of Securities Dealers, Inc. (the "Listing Exception").
Parent anticipates that such record date will be after the date the Offer is
consummated. Parent currently intends to avail itself of the Listing Exception
if it is available and Parent cannot effect a short-form merger under the
NYBCL. Parent currently intends not to seek delisting of the Shares from the
NYSE prior to the Effective Time, although such Shares may be delisted by the
NYSE. See Section 7. The foregoing summary of Sections 623 and 910 does not
purport to be complete and is qualified in its entirety by reference to
Sections 623 and 910.

  THE FOREGOING SUMMARY OF THE RIGHTS OF DISSENTING STOCKHOLDERS UNDER THE
NYBCL DOES NOT PURPORT TO BE A COMPLETE STATEMENT OF THE PROCEDURES TO BE
FOLLOWED BY HOLDERS OF SHARES DESIRING TO EXERCISE ANY APPRAISAL RIGHTS
AVAILABLE UNDER THE NYBCL AND IS QUALIFIED IN ITS ENTIRETY BY THE FULL TEXT OF
SECTION 623 OF THE NYBCL. THE PRESERVATION AND EXERCISE OF APPRAISAL RIGHTS
REQUIRE STRICT ADHERENCE TO THE APPLICABLE PROVISIONS OF THE NYBCL. FAILURE TO
FOLLOW THE STEPS REQUIRED BY SECTION 623 OF THE NYBCL FOR PERFECTING APPRAISAL
RIGHTS MAY RESULT IN THE LOSS OF SUCH RIGHTS.
 
  Rule 13e-3. The Commission has adopted Rule 13e-3 under the Exchange Act
which is applicable to certain "going private" transactions and which may
under certain circumstances be applicable to the Merger or another business
combination following the purchase of Shares pursuant to the Offer in which
Purchaser seeks to acquire the remaining Shares not held by it. Purchaser
believes, however, that Rule 13e-3 will not be applicable to the Merger
because it is anticipated that the Merger would be effected within one year
following consummation of the Offer and in the Merger stockholders would
receive the same price per Share as paid in the Offer. If Rule 13e-3 were
applicable to the Merger, it 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
minority stockholders in such a transaction, be filed with the Commission and
disclosed to minority stockholders prior to consummation of the transaction.
The purchase of a substantial number of Shares pursuant to the Offer may
result in the Company being able to terminate its Exchange Act registration,
although Parent has no current intention to do so prior to the Effective Time.
See Section 7. If such registration were terminated, Rule 13e-3 would be
inapplicable to any such future Merger or such alternative transaction.
 
  14. DIVIDENDS AND DISTRIBUTIONS.
 
  The Company and its subsidiaries have agreed not to, without the prior
written consent of Parent, declare or pay any dividend or other distribution
with respect to any of its capital stock except that the Company may declare
and pay to holders of Shares regular quarterly cash dividends not to exceed
$0.14 per Share per fiscal quarter, including the regular quarterly cash
dividend of $0.14 per Share declared on December 20, 1998 and scheduled to be
paid on January 15, 1999 to stockholders of record on January 4, 1999.
 
  If, on or after December 20, 1998, the Company should (a) split, combine or
otherwise change the Shares or its capitalization, (b) acquire or otherwise
cause a reduction in the number of outstanding Shares or other securities or
(c) issue or sell additional Shares (other than the issuance of Shares upon
the exercise of Options outstanding at December 20, 1998 in accordance with
the terms thereof (as in effect on December 20, 1998)), shares of any other
class of capital stock, other voting securities or any securities convertible
into, or rights, warrants or options, conditional or otherwise, to acquire,
any of the foregoing, then, subject to the provisions of Section 15,
Purchaser, in its sole discretion, may make such adjustments as it deems
appropriate in the Offer Price and other terms of the Offer, including,
without limitation, the number or type of securities offered to be purchased.
 
  If, on or after December 20, 1998, the Company should declare or pay any
cash dividend on the Shares or other distribution on the Shares (other than
regular quarterly dividends not to exceed $0.14 per Share per fiscal quarter),
or issue with respect to the Shares or any additional Shares, shares of any
other class of capital stock, other voting securities or any securities
convertible into, or rights, warrants or options, conditional or otherwise, to
acquire, any of the foregoing, payable or distributable to stockholders of
record on a date prior to the transfer of Shares purchased pursuant to the
Offer to the Purchaser or its nominee or transferee on the Company's stock
transfer records, then, subject to the provisions of Section 15, (a) the Offer
Price may, in the sole discretion of Purchaser, be reduced by the amount of
any such cash dividend or cash distribution and (b) the whole of any such
noncash dividend, distribution or
 
                                      40
<PAGE>
 
issuance to be received by the tendering stockholders will (i) be received and
held by the tendering stockholders for the account of Purchaser and will be
required to be promptly remitted and transferred by each tendering stockholder
to the Depositary for the account of Purchaser, accompanied by appropriate
documentation of transfer, or (ii) at the direction of Purchaser, be exercised
for the benefit of Purchaser, in which case the proceeds of such exercise will
promptly be remitted to Purchaser. Pending such remittance and subject to
applicable law, Purchaser will be entitled to all rights and privileges as
owner of any such noncash dividend, distribution, issuance or proceeds and may
withhold the entire Offer Price or deduct from the Offer Price the amount or
value thereof, as determined by Purchaser in its sole discretion.
 
  Pursuant to the terms of the Merger Agreement, the Company is prohibited
from taking any of the actions described in the two preceeding paragraphs, and
nothing herein shall constitute a waiver by Purchaser or Parent of any of its
rights under the Merger Agreement or a limitation of remedies available to
Purchaser or Parent for any breach of the Merger Agreement, including
termination thereof.
 
  15. CERTAIN CONDITIONS OF THE OFFER.
 
  Notwithstanding any other provision of the Offer but subject to the terms
and conditions of the Merger Agreement, in addition to (and not in limitation
of) Purchaser's rights pursuant to the Merger Agreement to extend and amend
the Offer in accordance with the Merger Agreement, Purchaser shall not be
required to accept for payment or, subject to Rule 14e-1(c) of the Exchange
Act, pay for and may delay the acceptance for payment of or, subject to Rule
14e-1(c) of the Exchange Act, the payment for, any Shares not theretofore
accepted for payment or paid for, and may terminate or amend the Offer if (i)
the Minimum Condition has not been satisfied, (ii) any applicable waiting
period under the HSR Act shall not have expired or been terminated or (iii) at
any time on or after December 20, 1998 and prior to the time of acceptance of
such Shares for payment or the payment therefor, any of the following
conditions has occurred and continues to exist (and in the case of the
conditions set forth in paragraph (c), continue to exist as of the scheduled
expiration date of the Offer or have continued to exist for at least the
previous 10 business days), other than as a result of a breach by Parent or
Purchaser of its obligations under the Merger Agreement (including, without
limitation, the provisions described under "--Reasonable Best Efforts" in
Section 12):
 
    (a) the representation and warranty set forth in the Merger Agreement
  with regard to capitalization of the Company shall not be true and correct
  in all material respects or any other representations and warranties of the
  Company in the Merger Agreement (without regard to any materiality
  qualifiers contained therein) shall not be true and correct as of such time
  (other than to the extent such representations and warranties expressly
  relate to an earlier date, in which case such representations and
  warranties shall not be true and correct as of such date) except where the
  failure of such representations and warranties to be true and correct would
  not be reasonably likely to have a Material Adverse Effect (as defined
  below) on the Company and except where such failure shall have been cured
  prior to the earlier of (i) 10 business days following notice of such
  breach and (ii) two business days prior to the date on which the Offer
  expires; provided, however, that the Company shall have no right to cure
  such breach in the event that such breach by the Company was willful or
  intentional;
 
    (b) the Company shall not have performed and complied with, in all
  material respects (without reference to any materiality qualifications
  therein), all material covenants or agreements contained in the Merger
  Agreement and required to be performed or complied with by it and which
  breach shall not have been cured prior to the earlier of (i) 10 business
  days following notice of such breach and (ii) two business days prior to
  the date on which the Offer expires; provided, however, that the Company
  shall have no right to cure such
 
                                      41
<PAGE>
 
  breach in the event that such breach by the Company was willful or
  intentional or if such breach involves a breach of the provisions of the
  Merger Agreement relating to the solicitation and negotiation of
  Acquisition Proposals;
 
    (c) there shall have occurred and be continuing (i) any general
  suspension of trading in, or limitation on prices for, securities on the
  New York Stock Exchange (excluding any coordinated trading halt triggered
  as a result of a specified decrease in a market index), (ii) a declaration
  of a banking moratorium or any suspension of payments in respect of banks
  in the United States by any Governmental Entity, (iii) any mandatory
  limitation by any Governmental Entity on, or other event that materially
  and adversely affects, the extension of credit by banks or other lending
  institutions, (iv) a commencement of a war, armed hostilities or other
  national or international calamity directly or indirectly involving the
  United States, (v) any material adverse change in United States currency
  exchange rates or a suspension of, or limitation on, the markets therefor
  or (vi) in the case of any of the foregoing existing on the date of the
  Merger Agreement, a material acceleration or worsening thereof;
 
    (d) there shall have been instituted or pending any suit, action,
  investigation or proceeding ("Actions") by any Governmental Entity, or
  Parent, Purchaser or the Company shall have been notified by any
  Governmental Entity (or a representative thereof) of its present intention
  to commence, or recommend the commencement of, such an Action, (i)
  challenging the acquisition by Parent or Purchaser of any Shares, seeking
  to make illegal, materially delay, make materially more costly or otherwise
  directly or indirectly restrain or prohibit the making or consummation of
  the Offer and the Merger or any of the other Transactions, or seeking to
  obtain from the Company, Parent or Purchaser any damages that are material
  in relation to the Company and its subsidiaries taken as whole, (ii)
  seeking to prohibit or materially limit the ownership or operation by the
  Company, Parent or any of their respective subsidiaries or affiliates of a
  material portion of the businesses or assets of the Company and its
  subsidiaries, taken as a whole, or Parent and its subsidiaries, taken as a
  whole, or to compel the Company, Parent or any of their respective
  subsidiaries or affiliates to dispose of or hold separate a material
  portion of the businesses or assets of the Company and its subsidiaries,
  taken as a whole, or Parent and its subsidiaries, taken as a whole, or any
  of their respective subsidiaries or affiliates, as a result of the Offer,
  the Merger or any of the other Transactions, (iii) seeking to impose
  material limitations on the ability of Parent or Purchaser to acquire or
  hold, or exercise full rights of ownership of, any Shares accepted for
  payment pursuant to the Offer including, without limitation, the right to
  vote the Shares accepted for payment by it on all matters properly
  presented to the shareholders of the Company, (iv) seeking to prohibit
  Parent or any of its subsidiaries or affiliates from effectively
  controlling in any material respect a material portion of the business or
  operations of the Company and its subsidiaries, taken as a whole, (v)
  requiring divestiture by Purchaser or any of its affiliates of any Shares
  or (vi) which otherwise is reasonably likely to have a Material Adverse
  Effect on the Company or Parent;
 
    (e) there shall be any statute, rule, regulation, judgment, order or
  injunction (including with respect to competition or antitrust matters)
  enacted, entered, enforced, promulgated or issued with respect to or deemed
  applicable to, or any consent or approval withheld, or any other action
  shall be taken with respect to (i) Parent, the Company or any of their
  respective subsidiaries or affiliates or (ii) the Offer or the Merger or
  any of the other Transactions by any Governmental Entity or court,
  including without limitation any required approvals or waiting periods
  under German antitrust law (see Section 16), other than the application to
  the Offer or the Merger or any of the other Transactions of applicable
  waiting periods under the HSR Act, that has resulted or is reasonably
  likely to result, directly or indirectly, in any of the consequences
  referred to in clauses (i) though (v) of paragraph (d) above;
 
                                      42
<PAGE>
 
    (f) since the date of the Merger Agreement there shall have occurred any
  event, change, effect or development that, individually or in the
  aggregate, has had or is reasonably likely to have, a Material Adverse
  Effect on the Company;
 
    (g) the Board of Directors of the Company or any committee thereof shall
  have (i) withdrawn, or modified, amended or changed (including by amendment
  of the Schedule 14D-9), in a manner adverse to Parent or Purchaser, its
  approval or recommendation of the Offer, the Merger Agreement and the
  Merger or any of the other Transactions, (ii) approved or recommended to
  the Company's stockholders an Acquisition Proposal or any other acquisition
  of Shares other than the Offer and the Merger or (iii) adopted any
  resolution to effect any of the foregoing;
 
    (h) the Merger Agreement shall have been terminated in accordance with
  its terms; or
 
    (i) any person (which includes a "person" as such term is defined in
  Section 13(d)(3) of the Exchange Act) other than Parent, Purchaser, any of
  their affiliates, or any group of which any of them is a member, shall have
  acquired beneficial ownership of more than 20 percent of the Shares or
  shall have consummated or entered into a definitive agreement or an
  agreement in principle to consummate an Acquisition Proposal;
 
which, in the sole judgment of Purchaser, in any such case, makes it
inadvisable to proceed with the Offer or with such acceptance for payment,
purchase of, or payment for Shares.
 
  The foregoing conditions are for the sole benefit of Purchaser and Parent
and may, subject to the terms of the Merger Agreement, be waived by Purchaser
or Parent, in whole or in part, at any time and from time to time, in the sole
discretion of Purchaser or Parent. The failure by Purchaser or Parent or any
of their respective affiliates at any time to exercise any of the foregoing
rights will not be deemed a waiver of any right, the waiver of any such right
with respect to particular facts and circumstances shall not be deemed a
waiver with respect to any other facts and circumstances and each right will
be deemed an ongoing right which may be asserted at any time and from time to
time.
 
  "Material Adverse Effect" means (i) any adverse change or effect in the
financial condition, assets, liabilities, business, properties or results of
operations of a specified person or its subsidiaries (other than changes or
effects relating to general economic, financial or industry conditions), which
change or effect is material, individually or in the aggregate, to the
specified person and its subsidiaries taken as a whole, or (ii) any event,
matter, condition or effect which prevents or materially delays consummation
of the Transactions.
 
  16. CERTAIN LEGAL MATTERS AND REGULATORY APPROVALS.
 
  General. Except as described in this Section 16, based on a review of
publicly available filings made by the Company with the Commission and other
publicly available information concerning the Company, neither Purchaser nor
Parent is aware of any license or regulatory permit that appears to be
material to the business of the Company and its subsidiaries, taken as a
whole, that might be adversely affected by the acquisition of Shares by Parent
or Purchaser pursuant to the Offer, the Merger or otherwise, or of any
approval or other action by any governmental, administrative or regulatory
agency or authority, domestic or foreign, that would be required prior to the
acquisition of Shares by Purchaser pursuant to the Offer, the Merger or
otherwise. Should any such approval or other action be required, Purchaser and
Parent presently contemplate that such approval or other action will be
sought, except as described below under "--State Antitakeover Statutes."
While, except as otherwise described in this Offer to Purchase, Purchaser does
not presently intend to delay the acceptance for payment of, or payment for,
Shares tendered pursuant to the Offer pending the outcome of any such matter,
there can be no assurance that any such approval or other action, if needed,
would
 
                                      43
<PAGE>
 
be obtained or would be obtained without substantial conditions or that
failure to obtain any such approval or other action might not result in
consequences adverse to the Company's business or that certain parts of the
Company's business might not have to be disposed of, or other substantial
conditions complied with, in the event that such approvals were not obtained
or such other actions were not taken or in order to obtain any such approval
or other action. If certain types of adverse action are taken with respect to
the matters discussed below, Purchaser could decline to accept for payment, or
pay for, any Shares tendered. See Section 15 for certain conditions to the
Offer, including conditions with respect to governmental actions.
 
  State Antitakeover Statutes. The Company is incorporated under the laws of
New York. In general, Section 912 of the NYBCL prohibits a New York
corporation from engaging in a "Business Combination" (defined as any of a
variety of transactions including mergers) with an "Interested Shareholder"
(defined generally as a person owning shares entitled to cast at least 20% of
the voting power of a corporation) for a period of five years following the
date such person became an Interested Shareholder, unless, before such person
became an Interested Shareholder, the corporation's board of directors
approved either the Business Combination or the transaction in which the
stockholder became an Interested Shareholder. The Company has represented in
the Merger Agreement that the Company Board has taken all action necessary to
render Section 912 of the NYBCL inapplicable to Parent and Purchaser, the
Offer, the Merger, the Tender and Option Agreement, the Merger Agreement and
the other Transactions.
 
  If an assertion is made that Parent or Purchaser has not complied with the
provisions of any state takeover statute, Parent and Purchaser reserve the
right to challenge the validity or applicability of any state law allegedly
applicable to the Merger and nothing in this Offer to Purchase nor any action
taken in connection herewith is intended as a waiver of that right.
 
  Article 16 of the NYBCL requires the bidder for the shares of a New York
corporation to file a registration statement with the attorney general and to
satisfy certain disclosure requirements. Parent and Purchaser have filed such
a registration statement and this Offer to Purchase sets forth all of the
information required to be disclosed pursuant to Article 16 of the NYBCL.
 
  A number of states have adopted takeover laws and regulations that purport,
to varying degrees, to apply to attempts to acquire corporations that are
incorporated in such states, or whose business operations have substantial
economic effects in such states, or which have substantial assets, security
holders, employees, principal executive offices or principal places of
business in such states. In EDGAR V. MITE CORP., the Supreme Court of the
United States (the "Supreme Court") invalidated on constitutional grounds the
Illinois Business Takeover statute, which, as a matter of state securities
law, made certain corporate acquisitions more difficult. However, in 1987, in
CTS CORP. V. DYNAMICS CORP. OF AMERICA, the Supreme Court held that the State
of Indiana may, as a matter of corporate law and, in particular, with respect
to those aspects of corporate law concerning corporate governance,
constitutionally disqualify a potential acquiror from voting on the affairs of
a target corporation without the prior approval of the remaining stockholders.
The state law before the Supreme Court was by its terms applicable only to
corporations that had a substantial number of stockholders in the state and
were incorporated there. Subsequently, a number of Federal courts have ruled
that various state takeover statutes were unconstitutional insofar as they
apply to corporations incorporated outside the state of enactment.
 
  Parent and Purchaser do not believe that the antitakeover laws and
regulations of any state other than the State of New York will by their terms
apply to the Offer, and, except as set forth above with respect to the NYBCL,
neither Parent nor Purchaser has attempted to comply with any state
antitakeover statute or regulation. Purchaser reserves the right to challenge
the
 
                                      44
<PAGE>
 
applicability or validity of any state law purportedly applicable to the Offer
or the Merger and nothing in this Offer to Purchase or any action taken in
connection with the Offer or the Merger is intended as a waiver of such right.
If it is asserted that any state antitakeover statute is applicable to the
Offer or the Merger and an appropriate court does not determine that it is
inapplicable or invalid as applied to the Offer or the Merger, Purchaser might
be required to file certain information with, or to receive approvals from,
the relevant state authorities, and Purchaser might be unable to accept for
payment or pay for Shares tendered pursuant to the Offer or may be delayed in
continuing or consummating the Offer or the Merger. In such case, Purchaser
may not be obligated to accept for payment, or pay for, any Shares tendered
pursuant to the Offer. See Section 15.
 
  The Company has agreed in the Merger Agreement that it and its Board of
Directors will (i) take all action necessary to ensure that no state takeover
statute or similar statute or regulation is or becomes applicable to the
Transactions and (ii) if any state takeover statute or similar statute or
regulation becomes applicable to the Transactions, take all action necessary
to ensure that the Transactions may be consummated as promptly as practicable
on the terms contemplated by the Merger Agreement and the Tender and Option
Agreement and otherwise to minimize the effect of such statute or regulation
on the Transactions.
 
  United States Antitrust. The Offer and the Merger are subject to the HSR
Act, which provides that certain acquisition transactions may not be
consummated unless certain information has been furnished to the Antitrust
Division of the United States Department of Justice (the "Antitrust Division")
and the United States Federal Trade Commission (the "FTC") and certain waiting
period requirements have been satisfied.
 
  The rules promulgated by the FTC require the filing by each of Parent and
the Company of a Notification and Report Form with respect to the Offer under
the HSR Act. Parent expects to make the required filing on or about December
23, 1998. The waiting period under the HSR Act with respect to the Offer will
expire at 11:59 p.m., New York City time, on the fifteenth day after the date
Parent's form was filed unless early termination of the waiting period is
granted. However, the Antitrust Division or the FTC may extend the waiting
period by requesting additional information or documentary material from
Parent. If such a request is made, such waiting period will expire at 11:59
p.m., New York City time, on the tenth day after substantial compliance by
Parent with such request. Only one extension of the waiting period pursuant to
a request for additional information is authorized by the HSR Act. Thereafter,
such waiting period may be extended only by court order or with the consent of
Parent. In practice, complying with a request for additional information or
material can take a significant amount of time. In addition, if the Antitrust
Division or the FTC raises substantive issues in connection with a proposed
transaction, the parties frequently engage in negotiations with the relevant
governmental agency concerning possible means of addressing those issues and
may agree to delay consummation of the transaction while such negotiations
continue. The Purchaser will not accept for payment Shares tendered pursuant
to the Offer unless and until the waiting period requirements imposed by the
HSR Act with respect to the Offer have been satisfied. See Section 15.
 
  The Notification and Report Form filed described above is also applicable to
the Purchase Option granted to Parent and Purchaser pursuant to the Tender and
Option Agreement. Under the provisions of the HSR Act applicable to the
Purchase Option, the purchase of Shares pursuant to the Purchase Option may
not be consummated until the expiration of a 30-calendar day waiting period
following the filing by Parent, unless both the Antitrust Division and the FTC
terminate the waiting period thereto. If, within such 30-calendar day waiting
period, either the Antitrust Division or the FTC requests additional
information or documentary material from
 
                                      45
<PAGE>
 
Parent or the Company, the waiting period would be extended for an additional
20 calendar days following substantial compliance by Parent or the Company, as
the case may be, with such request. Thereafter, the waiting period could be
extended only by court order. Only one extension of such waiting period
pursuant to a request for additional information is authorized by the HSR Act
and the rules promulgated thereunder, except by court order. Pursuant to the
Tender and Option Agreement, if the Purchase Option becomes exercisable, it
would continue to be exercisable until 10 days after the waiting period
(including as extended) under the HSR Act has expired.
 
  The FTC and the Antitrust Division frequently scrutinize the legality under
the Antitrust Laws (as defined below) of transactions such as Purchaser's
acquisition of Shares pursuant to the Offer and the Merger. At any time before
or after Purchaser's acquisition of Shares, the Antitrust Division or the FTC
could take such action under the Antitrust Laws as it deems necessary or
desirable in the public interest, including seeking to enjoin the acquisition
of Shares pursuant to the Offer or otherwise seeking divestiture of Shares
acquired by Purchaser or divestiture of substantial assets of Parent or its
subsidiaries. Private parties, as well as state governments, may also bring
legal action under the Antitrust Laws under certain circumstances. Based upon
an examination of publicly available information provided by the Company
relating to the businesses in which the Company and its subsidiaries are
engaged, Parent and Purchaser believe that the acquisition of Shares by
Purchaser will not violate the Antitrust Laws. Nevertheless, there can be no
assurance that a challenge to the Offer or other acquisition of Shares by
Purchaser on antitrust grounds will not be made or, if such a challenge is
made, of the result. See Section 15 for certain conditions to the Offer,
including conditions with respect to litigation and certain government
actions.
 
  As used in this Offer to Purchase, "Antitrust Laws" shall mean and include
the Sherman Act, as amended, the Clayton Act, as amended, the HSR Act, the
Federal Trade Commission Act, as amended, and all other Federal, state and
foreign statutes, rules, regulations, orders, decrees, administrative and
judicial doctrines, and other laws that are designed or intended to prohibit,
restrict or regulate actions having the purpose or effect of monopolization or
restraint of trade.
 
  German Antitrust. Under German laws and regulations relating to the
regulation of monopolies and competition, certain acquisition transactions may
not be consummated in Germany unless certain information has been furnished to
the German Federal Cartel Office (the "FCO") and certain waiting period
requirements have been satisfied without issuance by the FCO of an order to
refrain. The purchase of Shares by Purchaser pursuant to the Offer and the
consummation of the Merger may be subject to such requirements. Under such
laws, the FCO has one month (unless earlier terminated by the FCO) from the
time of filing of such information with the FCO to advise the parties of its
intention to investigate the Offer and the Merger, in which case the FCO has
four months from the date of filing in which to take steps to oppose the Offer
and the Merger. Parent intends to file promptly the required notification with
the FCO, if applicable, and request early termination of the one-month waiting
period. While Parent does not believe that there is any basis for the FCO to
investigate the Offer and the Merger, there can be no assurance that the FCO
will not investigate or oppose the transactions or that early termination of
the waiting period will be granted.
 
  OTHER FOREIGN APPROVALS. According to publicly available information, the
Company conducts business in a number of other foreign countries and
jurisdictions. In connection with the acquisition of the Shares pursuant to
the Offer or the Merger, the laws of certain of those foreign countries and
jurisdictions may require the filing of information with, or the obtaining of
the approval or consent of, governmental authorities in such countries and
jurisdictions. The governments in such countries and jurisdictions might
attempt to impose additional conditions on the Company's operations conducted
in such countries and jurisdictions as a result of the
 
                                      46
<PAGE>
 
acquisitions of the Shares pursuant to the Offer or the Merger. If such
approvals or consents are found to be required the parties intend to make the
appropriate filings and applications. In the event such a filing or
applications is made for the requisite foreign approvals or consents, there
can be no assurance that such approvals or consents will be granted and, if
such approvals or consents are received, there can be no assurance as to the
date of such approvals or consents. In addition, there can be no assurance
that Purchaser will be able to cause the Company or its subsidiaries to
satisfy or comply with such laws or that compliance or noncompliance will not
have adverse consequences for the Company or any subsidiary after purchase of
the Shares pursuant to the Offer or the Merger.
 
  17. FEES AND EXPENSES.
 
  Purchaser and Parent have retained D. F. King & Co., Inc. to serve as the
Information Agent and ChaseMellon Shareholder Services, L.L.C. to serve as the
Depositary in connection with the Offer. The Information Agent may contact
holders of Shares by personal interview, mail, telephone, telex, telegraph and
other methods of electronic communication and may request brokers, dealers,
banks, trust companies and other nominees to forward the Offer materials to
beneficial holders. The Information Agent and the Depositary will each receive
reasonable and customary compensation for their services, be reimbursed for
certain reasonable out-of-pocket expenses and be indemnified against certain
liabilities and expenses in connection with their services, including certain
liabilities under the Federal securities laws.
 
  Parent has engaged Deutsche Bank Securities to act as its financial advisor
and as the Dealer Manager. Pursuant to a letter agreement dated November 2,
1998, Parent has agreed to pay Deutsche Bank Securities for its services,
including its services as Dealer Manager, (i) $200,000 upon the execution of
such letter agreement (the "Upfront Fee") and (ii) $2,200,000 upon the
consummation of the Offer (against which the Upfront Fee will be credited),
for its services as financial advisor to Parent. Parent has also agreed to
reimburse Deutsche Bank Securities for all reasonable expenses, and to
indemnify Deutsche Bank Securities against liabilities and expenses in
connection with its services, including liabilities under Federal securities
laws.
 
  Except as set forth above, neither Parent nor Purchaser will pay any fees or
commissions to any broker or dealer or other person or entity in connection
with the solicitation of tenders of Shares pursuant to the Offer. Brokers,
dealers, commercial banks and trust companies will, upon request, be
reimbursed by Purchaser for customary mailing and handling expenses incurred
by them in forwarding the Offer materials to their customers.
 
  18. MISCELLANEOUS.
 
  The Offer is being made solely by this Offer to Purchase and the related
Letter of Transmittal and is being made to all holders of Shares. Purchaser is
not aware of any state where the making of the Offer is prohibited by
administrative or judicial action pursuant to any valid state statute. If
Purchaser becomes aware of any valid state statute prohibiting the making of
the Offer or the acceptance of the Shares pursuant thereto, Purchaser shall
make a good faith effort to comply with such statute or seek to have such
statute declared inapplicable to the Offer. If, after such good faith effort,
Purchaser cannot comply with such state statute, the Offer will not be made to
(nor will tenders be accepted from or on behalf of) holders of Shares in such
state. In those jurisdictions where the securities, blue sky or other laws
require the Offer to be made by a licensed broker or dealer, the Offer is
being made on behalf of Purchaser by the Dealer Manager or one or more
registered brokers or dealers licensed under the laws of such jurisdictions.

                   PLEASE READ THE INSTRUCTIONS SET FORTH IN
                     THIS LETTER OF TRANSMITTAL CAREFULLY
 
Ladies and Gentlemen:
 
  The undersigned hereby tenders to Lightning Acquisition Corp., a New York
corporation ("Purchaser") and a wholly owned subsidiary of Rohm and Haas
Company, a Delaware corporation ("Parent"), the above-described shares of
common stock, par value $1.00 per share (the "Shares"), of LeaRonal, Inc., a
New York corporation (the "Company"), pursuant to Purchaser's offer to
purchase all of the outstanding Shares at a price of $34.00 per Share, net to
the seller in cash, without interest (the "Offer Price") upon the terms and
subject to the conditions set forth in the Offer to Purchase dated December
23, 1998, and in this Letter of Transmittal (which, together with any
amendments or supplements thereto or hereto, collectively constitute the
"Offer"). The undersigned understands that Purchaser reserves the right to
transfer or assign, in whole at any time, or in part from time to time, to one
or more of its affiliates, the right to purchase all or any portion of the
Shares tendered pursuant to the Offer, but any such transfer or assignment
will not relieve Purchaser of its obligations under the Offer and will in no
way prejudice the rights of tendering stockholders to receive payment for
Shares validly tendered and accepted for payment pursuant to the Offer.
Receipt of the Offer is hereby acknowledged.
 
  The Offer is being made pursuant to an Agreement and Plan of Merger, dated
as of December 20, 1998 (the "Merger Agreement"), by and among Parent,
Purchaser and the Company.
 
  Upon the terms and subject to the conditions of the Offer (and if the Offer
is extended or amended, the terms of any such extension or amendment), subject
to, and effective upon, acceptance for payment of, and payment for, 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, Purchaser all
right, title and interest in and to all the Shares that are being tendered
hereby (and any and all non-cash dividends, distributions, rights, other
Shares or other securities issued or issuable in respect thereof on or after
December 20, 1998 (collectively, "Distributions")) and irrevocably constitutes
and appoints the Depositary the true and lawful agent and attorney-in-fact of
the undersigned with respect to such Shares (and all Distributions), with full
power of substitution (such power of attorney being deemed to be an
irrevocable power coupled with an interest), to (i) deliver certificates for
such Shares (and any and all Distributions), or transfer ownership of such
Shares (and any and all Distributions) on the account books maintained by the
Book-Entry Transfer Facility, together, in any such case, with all
accompanying evidences of transfer and authenticity, to or upon the order of
Purchaser, (ii) present such Shares (and any and all Distributions) for
transfer on the books of the Company, and (iii) receive all benefits and
otherwise exercise all rights of beneficial ownership of such Shares (and any
and all Distributions), all in accordance with the terms of the Offer.
 
  By executing this Letter of Transmittal, the undersigned hereby irrevocably
appoints Rajiv L. Gupta, Bradley J. Bell and Pierre Brondeau in their
respective capacities as officers or directors of Purchaser, and any
individual who shall thereafter succeed to any such office of Purchaser, and
each of them, and any other designees of Purchaser, the attorneys-in-fact and
proxies of the undersigned, each with full power of substitution, to vote at
any annual or special meeting of the Company's stockholders or any adjournment
or postponement thereof or otherwise in such manner as each such attorney-in-
fact and proxy or his substitute shall in his sole discretion deem proper with
respect to, to execute any written consent concerning any matter as each such
attorney-in-fact and proxy or his substitute shall in his sole discretion deem
proper with respect to, and to otherwise act as each such attorney-in-fact and
proxy or his substitute shall in his sole discretion deem proper with respect
to, all of the Shares (and any and all Distributions) tendered hereby and
accepted for payment by Purchaser. This appointment will be effective if and
when, and only to the extent that, Purchaser accepts such Shares for payment
pursuant to the Offer. This power of attorney and proxy are irrevocable and
are granted in consideration of the acceptance for payment of such Shares in
accordance with the terms of the Offer. Such acceptance for payment shall,
without further action, revoke any prior powers of attorney and proxies
granted by the undersigned at any
 
                                       3
<PAGE>
 
time with respect to such Shares (and any and all Distributions), and no
subsequent powers of attorney, proxies, consents or revocations may be given
by the undersigned with respect thereto (and, if given, will not be deemed
effective). Purchaser reserves the right to require that, in order for Shares
or other securities to be deemed validly tendered, immediately upon
Purchaser's acceptance for payment of such Shares, Purchaser must be able to
exercise full voting, consent and other rights with respect to such Shares
(and any and all Distributions), including voting at any meeting of the
Company's stockholders.
 
  The undersigned hereby represents and warrants that the undersigned has full
power and authority to tender, sell, assign and transfer the Shares tendered
hereby and all Distributions, that the undersigned owns the Shares tendered
hereby within the meaning of Rule 14e-4 promulgated under the Securities
Exchange Act of 1934, as amended (the "Exchange Act"), that the tender of the
tendered Shares complies with Rule 14e-4 under the Exchange Act, and that when
the same are accepted for payment by Purchaser, Purchaser will acquire good,
marketable and unencumbered title thereto and to all Distributions, free and
clear of all liens, restrictions, charges and encumbrances and the same will
not be subject to any adverse claims. The undersigned will, upon request,
execute and deliver any additional documents deemed by the Depositary or
Purchaser to be necessary or desirable to complete the sale, assignment and
transfer of the Shares tendered hereby and all Distributions. In addition, the
undersigned shall remit and transfer promptly to the Depositary for the
account of Purchaser all Distributions in respect of the Shares tendered
hereby, accompanied by appropriate documentation of transfer, and, pending
such remittance and transfer or appropriate assurance thereof, Purchaser shall
be entitled to all rights and privileges as owner of each such Distribution
and may withhold the entire purchase price of the Shares tendered hereby or
deduct from such purchase price, the amount or value of such Distribution as
determined by Purchaser in its sole discretion.
 
  All authority herein conferred or agreed to be conferred shall survive the
death or incapacity of the undersigned, and any obligation of the undersigned
hereunder shall be binding upon the heirs, executors, administrators, personal
representatives, trustees in bankruptcy, successors and assigns of the
undersigned. Except as stated in the Offer, this tender is irrevocable.
 
  The undersigned understands that the valid tender of Shares pursuant to any
one of the procedures described in Section 3 of the Offer to Purchase and in
the Instructions hereto will constitute a binding agreement between the
undersigned and Purchaser upon the terms and subject to the conditions of the
Offer (and if the Offer is extended or amended, the terms or conditions of any
such extension or amendment). Without limiting the foregoing, if the price to
be paid in the Offer is amended in accordance with the terms of the Merger
Agreement, the price to be paid to the undersigned will be the amended price
notwithstanding the fact that a different price is stated in this Letter of
Transmittal. The undersigned recognizes that under certain circumstances set
forth in the Offer to Purchase, Purchaser may not be required to accept for
payment any of the Shares tendered hereby.
 
  Unless otherwise indicated under "Special Payment Instructions," please
issue the check for the purchase price of all Shares purchased and/or return
any certificates for Shares not tendered or accepted for payment in the
name(s) of the registered holder(s) appearing above under "Description of
Shares Tendered." Similarly, unless otherwise indicated under "Special
Delivery Instructions," please mail the check for the purchase price of all
Shares purchased and/or return any certificates for Shares not tendered or not
accepted for payment (and any accompanying documents, as appropriate) to the
address(es) of the registered holder(s) appearing above under "Description of
Shares Tendered." In the event that the boxes entitled "Special Payment
Instructions" and "Special Delivery Instructions" are both completed, please
issue the check for the purchase price of all Shares purchased and/or return
any certificates evidencing Shares not tendered or not accepted for payment
(and any accompanying documents, as appropriate) in the name(s) of, and
deliver such check and/or return any such certificates (and any accompanying
documents, as appropriate) to, the person(s) so indicated. Unless otherwise
indicated herein in the box entitled "Special Payment Instructions," please
credit any Shares tendered herewith by book-entry transfer that are not
accepted for payment by crediting the account at the Book-Entry Transfer
Facility designated above. The undersigned recognizes that Purchaser has no
obligation, pursuant to the "Special Payment Instructions," to transfer any
Shares from the name of the registered holder thereof if Purchaser does not
accept for payment any of the Shares so tendered.

pursuant to the Offer, either (a) a properly completed and duly executed
Letter of Transmittal (or facsimile thereof), together with any required
signature guarantees or an Agent's Message (in connection with book-entry
transfer) and any other required documents, must be received by the Depositary
at one of its addresses set forth herein prior to the Expiration Date and
either (i) certificates for tendered Shares must be received by the Depositary
at one of such addresses prior to the Expiration Date or (ii) Shares must be

and in Section 3 of the Offer to Purchase and a Book-Entry Confirmation must
be received by the Depositary prior to the Expiration Date or (b) the
tendering stockholder must comply with the guaranteed delivery procedures set
forth herein and in Section 3 of the Offer to Purchase.
 
  Stockholders whose certificates for Shares are not immediately available or
who cannot deliver their certificates and all other required documents to the
Depositary prior to the Expiration Date or who cannot comply with the book-
entry transfer procedures on a timely basis may tender their Shares by
properly completing and duly executing the Notice of Guaranteed Delivery
pursuant to the guaranteed delivery procedure set forth herein and in Section
3 of the Offer to Purchase.
 
  Pursuant to such guaranteed delivery procedures, (i) such tender must be

executed Notice of Guaranteed Delivery, substantially in the form provided by
Purchaser, must be received by the Depositary prior to the Expiration Date and

with a properly completed and duly executed Letter of Transmittal (or a
facsimile thereof), with any required signature guarantees, or, in the case of
a book-entry transfer, an Agent's Message, and any other required documents
must be received by the Depositary within three trading days after the date of
execution of such Notice of Guaranteed Delivery. A "trading day" is any day on
which the New York Stock Exchange is open for business.
 
  The term "Agent's Message" means a message, transmitted by the Book-Entry
Transfer Facility to, and received by, the Depositary and forming a part of a
Book-Entry Confirmation, which states that such Book-Entry Transfer Facility
has received an express acknowledgment from the participant in such Book-Entry
Transfer Facility tendering the Shares, that such participant has received and
agrees to be bound by the terms of the Letter of Transmittal and that
Purchaser may enforce such agreement against the participant.

  The signatures on this Letter of Transmittal cover the Shares tendered

  THE METHOD OF DELIVERY OF THE SHARES, THIS LETTER OF TRANSMITTAL AND ALL
OTHER REQUIRED DOCUMENTS, INCLUDING DELIVERY THROUGH THE BOOK-ENTRY TRANSFER
FACILITY, IS AT THE ELECTION AND RISK OF THE TENDERING STOCKHOLDER. THE 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, REGISTERED MAIL WITH RETURN RECEIPT REQUESTED,
PROPERLY INSURED, IS RECOMMENDED. IN ALL CASES, SUFFICIENT TIME SHOULD BE
ALLOWED TO ENSURE TIMELY DELIVERY.
 
  No alternative, conditional or contingent tenders will be accepted, and no
fractional Shares will be purchased. All tendering stockholders, by executing
this Letter of Transmittal (or facsimile thereof), waive any right to receive
any notice of acceptance of their Shares for payment.
 
  3. INADEQUATE SPACE. If the space provided herein under "Description of

certificate numbers with respect to such Shares should be listed on a separate
signed schedule attached hereto.
 
  4. PARTIAL TENDERS. (Not applicable to stockholders who tender by book-entry
transfer). If fewer than all the Shares evidenced by any Share certificate
delivered to the Depositary herewith are to be tendered hereby, fill in the
number of Shares that are to be tendered in the box entitled "Number of Shares
Tendered." In any such case, new certificate(s) for the remainder of the
Shares that were evidenced by the old certificates will be sent to the
registered holder, unless otherwise provided in the appropriate box on this
Letter of Transmittal, as soon as practicable after the Expiration Date or the
termination of the Offer. All Shares represented by certificates delivered to
the Depositary will be deemed to have been tendered unless otherwise
indicated.
 
  5. SIGNATURES ON LETTER OF TRANSMITTAL; STOCK POWERS AND ENDORSEMENTS. If
this Letter of Transmittal is signed by the registered holder(s) of the Shares
tendered hereby, the signature(s) must correspond with the name(s) as written
on the face of the certificate(s) without alteration, enlargement or any
change whatsoever.
 
  If any of the Shares tendered hereby are held of record by two or more joint

  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

signed by a trustee, executor, administrator, guardian, attorney-in-fact,
officer of a corporation or other person acting in a fiduciary or
representative capacity, such person should so indicate when signing, and
proper evidence satisfactory to Purchaser of the authority of such person so
to act must be submitted. If this Letter of Transmittal is signed by the
registered holder(s) of the Shares listed and transmitted hereby, no
endorsements of Share certificates or separate stock powers are required
unless payment or certificates for Shares not tendered or not accepted for
payment are to be issued in the name of a person other than the registered
holder(s). Signatures on any such Share certificates or stock powers must be
guaranteed by an Eligible Institution.
 
  If this Letter of Transmittal is signed by a person other than the
registered holder(s) of the Shares evidenced by certificates listed and
transmitted hereby, the Share certificates must be endorsed or accompanied by
appropriate stock powers, in either case signed exactly as the name(s) of the
registered holder(s) appear(s) on the Share certificates. Signature(s) on any

  6. STOCK TRANSFER TAXES. Except as otherwise provided in this Instruction 6,
Purchaser will pay all stock transfer taxes with respect to the transfer and
sale of any Shares to it or its order pursuant to the Offer. If, however,
payment of the purchase price of any Shares purchased is to be made to, or if
certificates for Shares not tendered or not accepted for payment are to be
registered in the name of, any person other than the registered holder(s), or
if tendered certificates are registered in the name of any person other than
the person(s) signing this Letter of Transmittal, the amount of any stock
transfer taxes (whether imposed on the registered holder(s) or such other
person) payable on account of the transfer to such other person will be
deducted from the purchase price of such Shares purchased unless evidence
satisfactory to Purchaser of the payment of such taxes, or exemption
therefrom, is submitted.
 
  Except as provided in this Instruction 6, it will not be necessary for
transfer tax stamps to be affixed to the Share certificates evidencing the
Shares tendered hereby.
 
  7. SPECIAL PAYMENT AND DELIVERY INSTRUCTIONS. If a check for the purchase
price of any Shares accepted for payment is to be issued in the name of,
and/or Share certificates for Shares not accepted for payment or not tendered
are to be issued in the name of and/or returned to, a person other than the
signer of this Letter of Transmittal or if a check is to be sent, and/or such
certificates are to be returned, 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. Any
stockholder(s) delivering Shares by book-entry transfer may request that
Shares not purchased be credited to such account maintained at the Book-Entry
Transfer Facility as such stockholder(s) may designate in the box entitled
"Special Payment Instructions." If no such instructions are given, any such
Shares not purchased will be returned by crediting the account at the Book-
Entry Transfer Facility designated above as the account from which such Shares
were delivered.
 
  8. REQUESTS FOR ASSISTANCE OR ADDITIONAL COPIES. Questions and requests for
assistance or additional copies of the Offer to Purchase, this Letter of
Transmittal, the Notice of Guaranteed Delivery and the Guidelines for
Certification of Taxpayer Identification Number on Substitute Form W-9 may be
directed to the Information Agent or Dealer Manager at the addresses and phone
numbers set forth below, or from brokers, dealers, commercial banks or trust
companies.
 
  9. WAIVER OF CONDITIONS. Subject to the Merger Agreement, Purchaser reserves
the absolute right in its sole discretion to waive, at any time or from time
to time, any of the specified conditions of the Offer, in whole or in part, in
the case of any Shares tendered.
 
  10. 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 Substitute Form W-9 in this Letter of Transmittal and certify,
under penalties of perjury, that such TIN is correct and that such stockholder
is not subject to backup withholding.
 
  Backup withholding is not an additional income tax. Rather, the amount of
the backup withholding can be credited against the federal income tax
liability of the person subject to the backup withholding, provided that the
required information is given to the IRS. If backup withholding results in an
overpayment of tax, a refund can be obtained by the stockholder upon filing an
income tax return.
 
  The stockholder is required to give the Depositary the TIN (i.e., social
security number or employer identification number) of the record owner of the
Shares. If the Shares are held 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.
 
  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, such stockholder should
write "Applied For" in the space provided for the
 
                                       9
<PAGE>
 
TIN in Part 1 of the Substitute Form W-9 and sign and date the Substitute Form
W-9, and the stockholder or other payee must also complete the Certificate of
Awaiting Taxpayer Identification Number below in order to avoid backup
withholding. Notwithstanding that the Certificate of Awaiting Taxpayer
Identification Number is completed, the Depositary will withhold 31% on all
payments made prior to the time a properly certified TIN is provided to the
Depositary. However, such amounts will be refunded to such stockholder if a
TIN is provided to the Depositary within 60 days.
 
  Certain stockholders (including, among others, all corporations and certain
foreign individuals and entities) are not subject to backup withholding.
Noncorporate foreign stockholders should complete and sign the main signature
form and a Form W-8, Certificate of Foreign Status, a copy of which may be
obtained from the Depositary, in order to avoid backup withholding. See the
enclosed "Guidelines for Certification of Taxpayer Identification Number on
Substitute Form W-9" for more instructions.
 
  11. LOST, DESTROYED OR STOLEN SHARE CERTIFICATES. If any certificate(s)
representing Shares has been lost, destroyed or stolen, the stockholder should
promptly notify the Depositary by checking the box immediately preceding the
special payment/special delivery instructions and indicating the number of
Shares lost. The stockholder will then be instructed as to the steps that must
be taken in order to replace the Share certificate(s). This Letter of
Transmittal and related documents cannot be processed until the procedures for
replacing lost, destroyed or stolen Share certificates have been followed.
 
  IMPORTANT: THIS LETTER OF TRANSMITTAL (OR FACSIMILE HEREOF) TOGETHER WITH
ANY REQUIRED SIGNATURE GUARANTEES, OR, IN THE CASE OF A BOOK-ENTRY TRANSFER,
AN AGENT'S MESSAGE, AND ANY OTHER REQUIRED DOCUMENTS, MUST BE RECEIVED BY THE
DEPOSITARY PRIOR TO THE EXPIRATION DATE AND EITHER CERTIFICATES FOR TENDERED
SHARES MUST BE RECEIVED BY THE DEPOSITARY OR SHARES MUST BE DELIVERED PURSUANT
TO THE PROCEDURES FOR BOOK-ENTRY TRANSFER, IN EACH CASE PRIOR TO THE
EXPIRATION DATE, OR THE TENDERING STOCKHOLDER MUST COMPLY WITH THE PROCEDURES
FOR GUARANTEED DELIVERY.

                           IMPORTANT TAX INFORMATION
 
  Under Federal income tax law, a stockholder whose tendered Shares are
accepted for payment is required to provide the Depositary (as payer) with
such stockholder's correct taxpayer identification number on Substitute Form
W-9 below. If such stockholder is an individual, the taxpayer identification
number is his social security number. If the Depositary is not provided with
the correct taxpayer identification number, the stockholder may be subject to
a $50 penalty imposed by the Internal Revenue Service. In addition, payments
that are made to such stockholder with respect to Shares purchased pursuant to
the Offer may be subject to backup withholding.
 
  Certain stockholders (including, among others, all corporations, and certain
foreign individuals) are not subject to these backup withholding and reporting
requirements. In order for a foreign individual to qualify as an exempt
recipient, that stockholder must submit a statement, signed under penalties of
perjury, attesting to that individual's exempt status. Such statements can be
obtained from the Depositary. Exempt stockholders, other than foreign
individuals, should furnish their TIN, write "Exempt" on the face of the
Substitute Form W-9 below, and sign, date and return the Substitute Form W-9
to 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. 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.
 
  PURPOSE OF SUBSTITUTE FORM W-9
 
  To prevent backup withholding on payments that are made to a stockholder
with respect to Shares purchased pursuant to the Offer, the stockholder is
required to notify the Depositary of such stockholder's correct taxpayer
identification number by completing the form contained herein certifying that
the taxpayer identification number provided on Substitute Form W-9 is correct
(or that such stockholder is awaiting a taxpayer identification number).
 
  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. 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. 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, such
stockholder should write "Applied For" in the space provided for the TIN in
Part 1 of the Substitute Form W-9 and sign and date the Substitute Form W-9,
and the stockholder or other payee must also complete the Certificate of
Awaiting Taxpayer Identification Number below in order to avoid backup
withholding. Notwithstanding that the Certificate of Awaiting Taxpayer
Identification Number is completed, the Depositary will withhold 31% on all
payments made prior to the time a properly certified TIN is provided to the
Depositary. However, such amounts will be refunded to such stockholder if a
TIN is provided to the Depositary within 60 days.

To Our Clients:
 
  Enclosed for your consideration are the Offer to Purchase dated December 23,
1998 (the "Offer to Purchase") and the related Letter of Transmittal (which,
together with any amendments or supplements thereto, collectively constitute
the "Offer") in connection with the offer by Lightning Acquisition Corp., a
New York corporation ("Purchaser"), and a wholly owned subsidiary of Rohm and
Haas Company, a Delaware corporation ("Parent"), to purchase all outstanding
shares of common stock, par value $1.00 per share (the "Shares"), of LeaRonal,
Inc., a New York corporation (the "Company"), at $34.00 per Share, net to the
seller in cash, without interest, upon the terms and subject to the conditions
set forth in the Offer to Purchase and in the related Letter of Transmittal
enclosed herewith. WE ARE THE HOLDER OF RECORD OF SHARES HELD FOR YOUR
ACCOUNT. A TENDER OF SUCH SHARES CAN BE MADE ONLY BY US AS THE HOLDER OF
RECORD AND PURSUANT TO YOUR INSTRUCTIONS. THE ENCLOSED LETTER OF TRANSMITTAL
IS FURNISHED TO YOU FOR YOUR INFORMATION ONLY AND CANNOT BE USED BY YOU TO
TENDER SHARES HELD BY US FOR YOUR ACCOUNT.
 
  We request instructions as to whether you wish us to tender any or all of
the Shares held by us for your account, upon the terms and subject to the
conditions set forth in the Offer to Purchase. Your attention is invited to
the following:
 
    1. The offer price is $34.00 per Share, net to you in cash without
  interest.
<PAGE>
 
    2. The Offer is being made for all outstanding Shares.
 
    3. The Board of Directors of the Company has unanimously approved the
  Merger Agreement (as defined in the Offer to Purchase) and the transactions
  contemplated thereby, including the Offer and the Merger (each as defined
  in the Offer to Purchase), and determined that the Offer and the Merger are
  fair to, and in the best interests of, the Company's stockholders and
  recommends that stockholders accept the Offer and tender their Shares
  pursuant to the Offer.
 
    4. The Offer and withdrawal rights expire at 12:00 Midnight, New York
  City time, on Friday, January 22, 1999, unless the Offer is extended.
 
    5. The Offer is conditioned upon, among other things, there being validly
  tendered and not withdrawn prior to the expiration of the Offer a number of
  Shares representing at least two-thirds of the Fully Diluted Shares (as
  defined in the Offer to Purchase) and any applicable waiting period under
  the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended,
  having expired or been terminated. The Offer is also subject to the other
  conditions set forth in the Offer to Purchase. See Section 15 of the Offer
  to Purchase.
 
    6. Any stock transfer taxes applicable to the sale of Shares to Purchaser
  pursuant to the Offer will be paid by Purchaser, except as otherwise
  provided in Instruction 6 of the Letter of Transmittal.
 
  The Offer is made solely by the Offer to Purchase and the related Letter of
Transmittal and is being made to all holders of Shares. Purchaser is not aware
of any state where the making of the Offer is prohibited by administrative or
judicial action pursuant to any valid state statute. If Purchaser becomes
aware of any valid state statute prohibiting the making of the Offer or the
acceptance of the Shares pursuant thereto, Purchaser shall make a good faith
effort to comply with such statute or seek to have such statute declared
inapplicable to the Offer. If, after such good faith effort, Purchaser cannot
comply with such state statute, the Offer will not be made to (nor will
tenders be accepted from or on behalf of) holders of Shares in such state. In
those jurisdictions where the securities, blue sky or other laws require the
Offer to be made by a licensed broker or dealer, the Offer will be deemed to
be made on behalf of Purchaser by the Dealer Manager for the Offer or one or
more registered brokers or dealers licensed under the laws of such
jurisdictions.
 
  If you wish to have us tender any or all of your Shares, please so instruct
us by completing, executing and returning to us the instruction form set forth
on the reverse side of this letter. An envelope to return your instructions to
us is enclosed. If you authorize the tender of your Shares, all such Shares
will be tendered unless otherwise specified on the reverse side of this
letter. Your instructions should be forwarded to us in ample time to permit us
to submit a tender on your behalf prior to the expiration of the Offer.

Philadelphia, PA, December 21, 1998: Rohm and Haas Company (NYSE: ROH) and 
LeaRonal, Inc. (NYSE: LRI) of Freeport, New York, announced today they have 
signed a definitive merger agreement for Rohm and Haas to acquire all of the 
outstanding shares of LeaRonal, a maker of specialty chemicals for the 
electronics industry, for $34 per share. The value of the transaction is 
approximately $460 million. LeaRonal will be combined with Shipley Company, the 
cornerstone of Rohm and Haas's $400 million Electronic Materials business group.

LeaRonal, which reported $242 million in fiscal 1998 sales, is a rapidly growing
firm that develops and makes specialty chemical processes for the manufacture of

plating. LeaRonal also provides processes for metal-finishing applications.

Under the merger agreement, Rohm and Haas soon will commence a cash tender offer
for all the outstanding common shares of LeaRonal. Following the consummation of
the tender offer, Rohm and Haas will acquire through a merger all shares not 
purchased in the tender offer at the same price.

"This is an excellent opportunity for LeaRonal because it will accelerate the 
growth of our patented technologies into new markets around the world," said 
Ronald Ostrow, President and CEO of LeaRonal. Added Rajiv L. Gupta, Vice 
Chairman elect of Rohm and Haas and leader of the Electronic Materials business 
group, "This is a wonderful marriage of complementary technologies, geographic 
presence and cultures that share a strong entrepreneurial spirit. We are 
fortunate LeaRonal wants to join forces with us, for they are our partner of 
choice." Gupta continued, "We look forward to having LeaRonal and Shipley 
management working side by side to create a new organization that will bring 
cutting-edge technology and products to the electronics market faster and more 
efficiently."

The boards of directors of both firms have approved the transaction. In
addition, holders
                                   --more--

of approximately 30 percent of outstanding LeaRonal shares have agreed to tender
their shares and have granted Rohm and Haas an option to purchase those shares.

The tender offer is contingent upon at least two-thirds of LeaRonal 
fully-diluted shares being tendered and receipt of normal regulatory approvals. 
The offer will expire 20 business days after it is begun, unless extended or 
withdrawn.

<PAGE>
 
  THE OFFER IS CONDITIONED UPON, AMONG OTHER THINGS, (i) THERE BEING VALIDLY
TENDERED AND NOT WITHDRAWN PRIOR TO THE EXPIRATION OF THE OFFER A NUMBER OF
SHARES REPRESENTING AT LEAST TWO-THIRDS OF THE FULLY DILUTED SHARES (AS
DEFINED IN THE OFFER TO PURCHASE) AND (ii) ANY APPLICABLE WAITING PERIOD UNDER
THE HART-SCOTT-RODINO ANTITRUST IMPROVEMENTS ACT OF 1976 HAVING EXPIRED OR

IN THE OFFER TO PURCHASE. SEE SECTION 15 OF THE OFFER TO PURCHASE.
 
  The Offer is being made pursuant to an Agreement and Plan of Merger, dated as
of December 20, 1998 (the "Merger Agreement"), by and among Parent, Purchaser
and the Company. Pursuant to the Merger Agreement and in accordance with the New
York Business Corporation Law (the "NYBCL"), as promptly as practicable after
the completion of the Offer and satisfaction or waiver, if permissible, of all
conditions contained in the Merger Agreement, Purchaser will be merged with and
into the Company (the "Merger") and the Company will be the surviving
corporation in the Merger and a wholly owned subsidiary of Parent. At the
effective time of the Merger, each Share then outstanding, other than Shares
held by (i) the Company or any of its subsidiaries, (ii) the Parent or any of
its subsidiaries, including Purchaser, and (iii) stockholders who properly
perfect their dissenters' rights under the NYBCL, if applicable, will be
converted into the right to receive $34.00 in cash, without interest. The Merger
Agreement is more fully described in Section 12 of the Offer to Purchase.

 THE BOARD OF DIRECTORS OF THE COMPANY HAS UNANIMOUSLY APPROVED THE MERGER
AGREEMENT AND THE TRANSACTIONS CONTEMPLATED THEREBY, INCLUDING THE OFFER AND
THE MERGER, AND DETERMINED THAT THE OFFER AND THE MERGER ARE FAIR TO, AND IN
THE BEST INTERESTS OF, THE COMPANY'S STOCKHOLDERS AND RECOMMENDS THAT
STOCKHOLDERS ACCEPT THE OFFER AND TENDER THEIR SHARES PURSUANT TO THE OFFER.
 
  Simultaneously with the execution and delivery of the Merger Agreement, Parent
and Purchaser, on the one hand, and certain stockholders, on the other hand (the
"Certain Stockholders"), entered into a Tender and Option Agreement dated as of
December 20, 1998 (the "Tender and Option Agreement"). The Tender and Option
Agreement relates to the 3,619,664 issued and outstanding Shares owned by the
Certain Stockholders, representing approximately 29% of the Company's issued and
outstanding Shares, as well as Shares in respect of certain stock options owned
by Certain Stockholders. Pursuant to the Tender and Option Agreement, each
Certain Stockholder has agreed, among other things, to grant Purchaser an option
to purchase the Shares subject thereto upon the occurrence of certain events,
and to tender in the Offer, and not to withdraw therefrom, the Shares owned by
such Certain Stockholders, as well as any other Shares acquired prior to the
expiration of the Offer including pursuant to the exercise of such stock
Options. The Tender and Option Agreement is more fully described in Section 12
of the Offer to Purchase.
 
  For purposes of the Offer, Purchaser will be deemed to have accepted for
payment, and thereby purchased, Shares properly tendered to Purchaser and not
withdrawn, if, as and when Purchaser gives oral or written notice to the
Depositary (as defined in the Offer to Purchase) of its acceptance for payment
of such Shares. Upon the terms and subject to the conditions of 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 tendering stockholders for the purpose of receiving payment from
Purchaser and transmitting payment to tendering stockholders. In all cases,
payment for Shares accepted for payment pursuant to the Offer will be made
only after timely receipt by the Depositary of (i) certificates for such
Shares
 
                                       2

<PAGE>
 
(or a confirmation of a book-entry transfer of such Shares into the
Depositary's account at the Book-Entry Transfer Facility (as defined in the
Offer to Purchase)), (ii) a Letter of Transmittal (or facsimile thereof),
properly completed and duly executed, with any required signature guarantees,
or, in the case of a book-entry transfer, an Agent's Message (as defined in
the Offer to Purchase) and (iii) any other documents required by the Letter of
Transmittal. The per Share consideration paid to any stockholder pursuant to the
Offer will be the highest per Share consideration paid to any other stockholder
pursuant to the Offer.

 UNDER NO CIRCUMSTANCES WILL INTEREST BE PAID ON THE PURCHASE PRICE TO BE PAID
BY PURCHASER FOR SUCH SHARES, REGARDLESS OF ANY EXTENSION OF THE OFFER OR ANY
DELAY IN MAKING SUCH PAYMENT.

 The term "Expiration Date" shall mean 12:00 Midnight, New York City time, on
Friday, January 22, 1999, unless and until Purchaser (in accordance with the
terms of the Merger Agreement), shall have extended the period of time during
which the Offer is open, in which event the term "Expiration Date" shall mean
the latest time and date at which the Offer, as so extended by Purchaser,
shall expire.
 
  Subject to the terms of the Merger Agreement and the applicable rules and
regulations of the Securities and Exchange Commission, Purchaser may, under
certain circumstances, (a) extend the period of time during which the Offer is
open and thereby delay acceptance for payment of and the payment for any Shares,
by giving oral or written notice of such extension to the Depositary and (b)
amend the Offer in any other respect by giving oral or written notice of such
amendment to the Depositary. Any extension, delay, waiver, amendment or
termination of the Offer will be followed as promptly as practicable by a public
announcement thereof, the announcement in the case of an extension to be issued
no later than 9:00 a.m., New York City time, on the next business day after the
previously scheduled Expiration Date. During any such extension, all Shares
previously tendered and not properly withdrawn will remain subject to the Offer,
subject to the right of a tendering stockholder to withdraw such stockholder's
Shares.

 Except as otherwise provided below, tenders of Shares made pursuant to the
Offer are irrevocable. Shares tendered pursuant to the Offer may be withdrawn
at any time prior to the Expiration Date and, unless theretofore accepted for
payment pursuant to the Offer, may also be withdrawn at any time after Saturday,
February 20, 1999. For a withdrawal to be effective, a written, telegraphic or
facsimile transmission notice of withdrawal must be timely received by the
Depositary at one of its addresses set forth in the Offer to Purchase. 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 name
of the registered holder of the Shares to be withdrawn, if different from the
name of the person who tendered the Shares. If certificates evidencing such
Shares to be withdrawn have been delivered or otherwise identified to the
Depositary, then, prior to the physical release of such certificates, the
serial numbers shown on such certificates must be submitted to the Depositary
and, unless such Shares have been tendered for the account of an Eligible
Institution (as defined in the Offer to Purchase), the signatures on the
notice of withdrawal must be guaranteed by an Eligible Institution. If Shares
have been delivered pursuant to the procedures for book-entry transfer set
forth in Section 3 of the Offer to Purchase, any notice of withdrawal must
also specify the name and number of the account at the Book-Entry Transfer
Facility to be credited with the withdrawn Shares and otherwise comply with
the Book-Entry Transfer Facility's procedures. Withdrawals of tenders of
Shares may not be rescinded, and any Shares properly withdrawn will thereafter
be deemed not validly tendered for purposes of the Offer. However, withdrawn
Shares may be retendered by again following one of the procedures described in
Section 3 of the Offer to Purchase at any time prior to the Expiration Date.
All questions as to the form and validity (including time of receipt) of
notices of withdrawal will be determined by Purchaser, in its sole discretion,
whose determination will be final and binding.

                                  ----------

          WHEREAS, the Board of Directors of the Company has determined that it
is fair to, advisable and in the best interests of the Company and the
shareholders of the Company to enter into and consummate this Agreement with
Purchaser, providing for the merger (the "Merger") of Purchaser with and into
the Company, with the Company as the Surviving Corporation, in accordance with
the New York Business Corporation Law (the "NYBCL") and the other transactions
contemplated hereby, upon the terms and subject to the conditions set forth
herein;

          WHEREAS, the Board of Directors of Purchaser has approved the Merger
of Purchaser with and into the Company and such other transactions in accordance
with the NYBCL upon the terms and subject to the conditions set forth herein;

          WHEREAS, the Company and Purchaser have agreed that, upon the terms
and subject to the conditions contained herein, Purchaser shall commence an
offer (as amended or supplemented in accordance with this Agreement, the
"Offer") to purchase for cash all of the issued and outstanding shares of common
stock, par value $1.00 per share (referred to herein as either the "Shares" or
"Company Common Stock"), of the Company at a price per Share of $34.00, net to
the seller in cash (the "Offer Price").

          WHEREAS, the Board of Directors of the Company has determined that the
consideration to be paid for each Share in the Offer and the Merger is fair to
the holders of such Shares and has resolved to recommend that the holders of
such Shares tender their Shares pursuant to the Offer and approve and adopt this
Agreement and the Merger upon the terms and subject to the conditions set forth
herein;

          WHEREAS, the Company, Parent and Purchaser desire to make certain
representations, warranties, covenants and agreements in connection with the
Offer and the Merger;

          WHEREAS, simultaneously with the execution and delivery of this
Agreement and in order to induce Parent and Purchaser to enter into this
Agreement, certain stockholders of the Company (the "Certain Stockholders") have
executed and delivered to Parent and Purchaser an agreement (the "Tender and
Option Agreement") pursuant to which the Certain Stockholders have agreed to
take specified actions in furtherance of the transactions contemplated by this
Agreement, including tendering their Shares into the Offer and granting Parent
and Purchaser the

Purchase Option (as defined in the Tender and Option Agreement) with respect to
such Shares; and

          WHEREAS, simultaneously with the execution and delivery of this
Agreement and in order to induce Parent and Purchaser to enter into this
Agreement, certain employees of the Company have entered into employment
agreements with the Company and certain stockholders of the Company's
subsidiaries have entered into shareholders agreements with the Company (the
"Other Agreements").

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

                                   ARTICLE I

                                   THE OFFER

     Section 1.1    The Offer.
                    ---------

          (a)  Subject to the provisions of this Agreement, and provided that
this Agreement shall not have been terminated in accordance with Section 8.1 and
so long as none of the events or circumstances set forth in Annex A hereto shall
have occurred and be existing, not later than the fifth business day from the
date of public announcement of the execution of this Agreement, Purchaser shall
commence (within the meaning of Rule 14d-2 under the Securities Exchange Act of
1934, as amended (the "Exchange Act")), the Offer at a price of $34.00 per Share
net to the seller in cash. The obligation of Purchaser to consummate the Offer,
to accept for payment and to pay for any Shares tendered pursuant to the Offer
shall be subject only to those conditions set forth in Annex A. Purchaser
expressly reserves the right, in its sole discretion, to waive any such
condition, provided that, without the consent of the Company, Purchaser shall
           -------- ----
not waive the Minimum Condition (as defined in Annex A), subject to Section
1.1(b). The initial expiration date of the Offer shall be the 20th business day
following the commencement of the Offer (determined using Rule 14d-1(c)(6) under
the Exchange Act).

          (b)  Purchaser expressly reserves the right, in its sole discretion,
to modify and make changes to the terms and conditions of the Offer, provided
                                                                     --------
that without the prior consent of the Company, no modification or change may be
- ----
made which (i) decreases the consideration payable in the Offer, (ii) changes
the form of consideration payable in the Offer (other than by adding
consideration), (iii) changes the Minimum Condition, provided that Purchaser may
                                                     -------- ----
reduce the Minimum Condition to an amount of Shares which is not less than a
majority of the Fully Diluted Shares so long as the affirmative vote of such
amount of Shares would provide the requisite shareholder approval for an
amendment to the Company's Certificate of Incorporation reducing the vote
required to approve a merger to a majority of the outstanding Shares, (iv)
decreases the maximum number of Shares sought pursuant to the Offer, (v)
adversely changes any

                                      -2-
<PAGE>
 
conditions to the Offer, or (vi) imposes additional conditions to the Offer.
Notwithstanding the foregoing, Purchaser may, without the consent of the
Company, (i) extend the Offer on one or more occasions for such period as may be
determined by Purchaser in its sole discretion (each such extension period not
to exceed 10 business days at a time), if at the then scheduled expiration date
of the Offer any of the conditions to Purchaser's obligations to accept for
payment and pay for Shares shall not be satisfied or waived, (ii) extend the
Offer for any period required by any rule, regulation, interpretation or
position of the Securities and Exchange Commission (the "SEC") or the staff
thereof applicable to the Offer, and (iii) extend the Offer on one occasion for
a period of not more than 10 business days if the Minimum Condition has been
satisfied but less than 90% of the Fully Diluted Shares have been validly
tendered and not properly withdrawn. Notwithstanding the foregoing, Purchaser
may not, without the Company's prior written consent, extend the Offer pursuant
to clause (i) of the preceding sentence if the events or circumstances set forth
in Annex A hereto shall have occurred as a result of Parent or Purchaser's
breach of this Agreement. It is agreed that the conditions to the Offer set
forth on Annex A are for the benefit of Purchaser and, except with respect to
the Minimum Condition as set forth in Section 1.1(a), may be waived by
Purchaser, in whole or in part at any time and from time to time, in its sole
discretion. On the terms and subject to the conditions of the Offer, Purchaser
shall pay for, and Parent shall cause Purchaser to pay for, all Shares validly
tendered and not withdrawn pursuant to the Offer promptly after the expiration
of the Offer.

          (C)  On the date of commencement of the Offer, Parent and Purchaser
shall file with the SEC a Tender Offer Statement on Schedule 14D-1 (together
with all amendments and supplements thereto and including the exhibits thereto,
the "Schedule 14D-1") with respect to the Offer which will comply in all
material respects with the provisions of applicable federal securities laws, and
will contain the offer to purchase relating to the Offer (the "Offer to
Purchase") and forms of related letters of transmittal and summary advertisement
(which documents, together with any supplements or amendments thereto and
including the exhibits thereto, are referred to herein collectively as the
"Offer Documents"). Parent shall deliver copies of the proposed forms of the
Schedule 14D-1 and the Offer Documents to the Company within a reasonable time
prior to the commencement of the Offer for review and comment by the Company and
its counsel. Parent agrees to provide the Company and its counsel in writing any
comments that Purchaser, Parent or their counsel may receive from the SEC or its
staff with respect to the Offer Documents promptly after the receipt thereof.
The Company, Parent and Purchaser shall promptly correct any information
provided by it for use in the Schedule 14D-1 or the Offer Documents that shall
have become false or misleading in any material respect and Parent and Purchaser
further agree to take all steps necessary to cause such Schedule 14D-1 or Offer
Documents as so corrected to be filed with the SEC and disseminated to the
shareholders of the Company, as and to the extent required by applicable federal
securities laws. 

     Section 1.2    Company Actions.
                    ---------------

          (a)  The Company hereby consents to the Offer and represents that its
Board of Directors, at a meeting duly called and held on December 20, 1998, has
duly and by unanimous

                                      -3-
<PAGE>
 
vote adopted resolutions approving the Offer, the Merger, this Agreement, the
Tender and Option Agreement and the Other Agreements and the other transactions
contemplated hereby and thereby (the "Transactions"), determining that the terms
of the Offer and the Merger are fair to, and in the best interests of, the
Company's shareholders and recommending acceptance of the Offer and adoption of
the Merger and this Agreement by the shareholders of the Company. The Company
hereby consents, subject to Section 6.1, to the inclusion in the Offer Documents
of the recommendations of the Company's Board of Directors described in this
Section 1.2. The Company has been advised that all of its directors and
executive officers intend either to tender their Shares pursuant to the Offer or
(solely in the case of directors and executive officers who would as a result of
the tender incur liability under Section 16(b) of the Exchange Act) to vote in
favor of the Merger.

          (b)  The Company shall file with the SEC on the date of the
commencement of the Offer a Solicitation/Recommendation Statement on Schedule
14D-9 (together with all amendments and supplements thereto and including the
exhibits thereto, the "Schedule 14D-9") which shall comply in all material
respects with the provisions of applicable federal securities laws, and will
contain such recommendations of the Board in favor of the Offer and the Merger,
and shall disseminate the Schedule 14D-9 as required by Rule 14d-9 promulgated
under the Exchange Act and shall mail such Schedule 14D-9 together with the
Offer Documents. The Company shall deliver the proposed forms of the Schedule
14D-9 and the exhibits thereto to Parent within a reasonable time prior to the
commencement of the Offer for review and comment by Parent and its counsel.
Parent and its counsel shall be given a reasonable opportunity to review any
amendments and supplements to the Schedule 14D-9 prior to their filing with the
SEC or dissemination to shareholders of the Company. The Company agrees to
provide Parent and its counsel in writing any comments that the Company or its
counsel may receive from the SEC or its staff with respect to the Schedule 14D-9
promptly after receipt thereof. Each of the Company, Parent and Purchaser shall
promptly correct any information provided by it for use in the Schedule 14D-9
that shall have become false or misleading in any material respect and the
Company further agrees to take all steps necessary to cause such Schedule 14D-9
as so corrected to be filed with the SEC and disseminated to the shareholders of
the Company, as and to the extent required by applicable federal securities
laws.

     Section 1.3    Stockholder Lists. In connection with the Offer, the Company
                    -----------------
shall promptly furnish to, or cause to be furnished to, Parent and Purchaser
mailing labels, security position listings, any non-objecting beneficial owner
lists and any available listing or computer file containing the names and
addresses of the record holders of the Shares as of a recent date and of those
Persons becoming record holders subsequent to such date (to the extent
available), together with all other information in the Company's possession or
control regarding the beneficial owners of Shares and shall furnish Parent and
Purchaser with such information and assistance as Parent, Purchaser or their
respective agents may reasonably request in communicating the Offer to the
record and beneficial holders of Shares. Subject to the requirements of law, and
except for such steps as are necessary to disseminate the Offer Documents and
any other documents necessary to consummate the Merger, Parent and Purchaser
shall, and shall cause each of their affiliates to, 

                                      -4-
<PAGE>
 
hold the information contained in any of such labels and lists in confidence,
use such information only in connection with the Offer and the Merger, and, if
this Agreement is terminated, deliver to the Company all copies of such
information or extracts therefrom then in their possession or under their
control.

     Section  1.4   Directors; Section 14(f). Immediately upon the acceptance
                    ------------------------
for payment of and payment for any Shares by Purchaser or any of its affiliates
pursuant to the Offer, Purchaser shall be entitled to designate such number of
directors, rounded up to the next whole number, on the Board of Directors of the
Company as will give Purchaser, subject to compliance with Section 14(f) of the
Exchange Act, representation on the Board of Directors of the Company equal to
the product of (i) the total number of directors on the Board of Directors of
the Company (giving effect to the increase in the size of such Board pursuant to
this Section 1.4) and (ii) the percentage that the number of votes represented
by Shares beneficially owned by Purchaser and its affiliates (including Shares
so accepted for payment and purchased) bears to the number of votes represented
by Shares then outstanding. In furtherance thereof, concurrently with such
acceptance for payment and payment for such Shares the Company shall, upon
request of Parent and compliance with Section 14(f) of the Exchange Act and Rule
14f-1 promulgated thereunder, use its best efforts promptly either to increase
the size of its Board of Directors or to secure the resignations of such number
of its incumbent directors, or both, as is necessary to enable such designees of
Parent to be so elected or appointed to the Company's Board of Directors, and
the Company shall take all actions available to the Company to cause such
designees of Parent to be so elected or appointed. At such time, the Company
shall, if requested by Parent, also use its reasonable best efforts to cause
persons designated by Parent to constitute at least the same percentage (rounded
up to the next whole number) as is on the Company's Board of Directors of (i)
each committee of the Company's Board of Directors, (ii) each board of directors
(or similar body) of each subsidiary of the Company and (iii) each committee (or
similar body) of each such board. Notwithstanding the foregoing, the Company
shall use its reasonable best efforts to ensure that, in the event that
Purchaser's designees are elected to the Board of Directors of the Company, such
Board of Directors shall have, at all times prior to the Effective Time, at
least three directors who are directors on the date of this Agreement and who
are not officers of the Company, Parent or any of their respective subsidiaries
(the "Independent Directors"); and provided further, that, in such event, if the
                                   -------- -------
number of Independent Directors shall be reduced below three for any reason
whatsoever any remaining Independent Directors (or Independent Director, if
there shall be only one remaining) may designate persons to fill such vacancies
who shall be deemed to be Independent Directors for purposes of this Agreement
or, if no Independent Directors then remain, the other directors may designate
three persons to fill such vacancies who shall not be officers or affiliates of
the Company, Parent or any of their respective subsidiaries, and such persons
shall be deemed to be Independent Directors for purposes of this Agreement.
Subject to applicable law, the Company shall promptly take all action requested
by Parent necessary to effect any such election, including mailing to its
shareholders the information required by Section 14(f) of the Exchange Act and
Rule 14(f)-1 promulgated thereunder (or, at Parent's request, furnishing such
information to Parent for inclusion in the Offer Documents initially filed with
the SEC and distributed to the stockholders of the Company) as is necessary to

                                      -5-
<PAGE>
 
enable Parent's designees to be elected to the Company's Board of Directors.
From and after the time, if any, that Parent's designees constitute a majority
of the Company's Board of Directors, any amendment of this Agreement, any
termination of this Agreement by the Company, any extension of time for
performance of any of the obligations of Parent or Purchaser hereunder, any
waiver of any condition to the Company's obligations hereunder or any of the
Company's rights hereunder or other action by the Company hereunder may be
effected only by the action of a majority of the Independent Directors of the
Company, which action shall be deemed to constitute the action of any committee
specifically designated by the Board of Directors of the Company to approve the
actions contemplated hereby and the full Board of Directors of the Company;
provided, that, if there shall be no Independent Directors, such actions may be
- --------  ----
effected by majority vote of the entire Board of Directors of the Company,
except that no such action shall amend the terms of this Agreement or modify the
terms of the Offer or the Merger in a manner materially adverse to the holders
of Shares.

                                  ARTICLE II

                                  THE MERGER

satisfaction or waiver of the conditions set forth in Article VII. Following the
Merger, the Company shall continue as the surviving corporation (the "Surviving
Corporation") under the name "LeaRonal, Inc." and shall continue its existence

Purchaser shall cease. At the election of Parent, any direct or indirect wholly

corporation in the Merger.

     Section 2.2    Effective Time.  As soon as practicable after the
                    --------------
satisfaction or waiver of the conditions set forth in Article VII, the parties
hereto shall cause the Merger to be consummated by filing a certificate of
merger (the "Certificate of Merger") with the Department of State of the State
of New York (the "New York Department"), in such form as required by and
executed in accordance with the relevant provisions of the NYBCL (the date and
time of the filing of the Certificate of Merger with the New York Department (or
such later time as is specified in the Certificate of Merger) being the
"Effective Time").

     Section 2.3    Effects of the Merger. The Merger shall have the effects set
                    ---------------------
forth in the applicable provisions of the NYBCL. Without limiting the generality
of the foregoing and subject thereto, at the Effective Time all the property,
rights, privileges, immunities, powers and franchises of the Company and

and duties of the Company and Purchaser shall become the debts, liabilities and
duties of the Surviving Corporation.

     Section  2.4   Certificate of Incorporation; By-Laws. (a) At the Effective
                    -------------------------------------
Time and without any further action on the part of the Company and Purchaser,
the Certificate of Incorporation of the Purchaser (the "Certificate of
Incorporation"), as in effect immediately prior to the Effective Time until
thereafter further amended as provided therein and under the NYBCL, shall be the
certificate of incorporation of the Surviving Corporation following the Merger.

          (b)  At the Effective Time and without any further action on the part
of the Company and Purchaser, the Bylaws of the Purchaser shall be the Bylaws of
the Surviving Corporation and thereafter may be amended or repealed in
accordance with their terms or the Certificate of Incorporation of the Surviving
Corporation and as provided by law.

     Section 2.5    Directors and Officers.  The directors of Purchaser
                    ----------------------
immediately prior to the Effective Time shall be the initial directors of the
Surviving Corporation, each to hold office in accordance with the Certificate of
Incorporation and Bylaws of the Surviving Corporation, and the officers of the
Company immediately prior to the Effective Time shall be the initial officers of
the Surviving Corporation, in each case until their respective successors are
duly elected or appointed (as the case may be) and qualified.

     Section 2.6    Conversion of Securities.  At the Effective Time, by virtue
                    ------------------------
of the Merger and without any action on the part of Purchaser, the Company or
the holders of any of the following securities:

               (i)   Each share of common stock of Purchaser issued and
     outstanding immediately prior to the Effective Time shall be converted into
     one validly issued, fully paid and nonassessable share of common stock of
     the Surviving Corporation.

               (ii)  Each Share held in the treasury of the Company and each
     Share owned by Purchaser or any direct or indirect subsidiary of the
     Company, in each case immediately prior to the Effective Time, shall be
     cancelled and retired without any conversion thereof and no payment or
     distribution shall be made with respect thereto.

               (iii) Each issued and outstanding Share (other than Shares
     cancelled pursuant to Section 2.6(ii) and any Dissenting Shares (as defined
     in Section 2.7(a)) shall be converted into the right to receive $34.00 in
     cash or any higher price that may be paid pursuant to the Offer (the
     "Merger Consideration") payable to the holder thereof, without interest,
     upon surrender of the certificate formerly representing such share in the
     manner provided in Section 2.8, less any required withholding taxes.

     Section  2.7   Dissenting Shares.  (a) Notwithstanding anything in this
                    -----------------
Agreement to the contrary, Shares that are issued and outstanding immediately
prior to the Effective Time and which are held by shareholders who have not
voted such Shares in favor of the Merger (or consented thereto in writing), who
shall have delivered a written objection to the Merger and a demand for
appraisal of such Shares in accordance with Sections 623 and 910 of the NYBCL

                                      -7-
<PAGE>
 
(insofar as such Sections are applicable to the Merger), and who shall not have
failed to perfect or shall not have effectively withdrawn or lost their rights
to appraisal and payment under the NYBCL (the "Dissenting Shares"), shall not be
converted into the right to receive the Merger Consideration, but shall instead
entitle the holder thereof to receive that consideration determined pursuant to
Sections 623 and 910 of the NYBCL; provided, however, that if such holder shall
have failed to perfect or shall have effectively withdrawn or lost such holder's
right to appraisal and payment under the NYBCL, such holder's Shares shall
thereupon be deemed to have been converted, at the Effective Time, into the
right to receive the Merger Consideration, without any interest thereon.

          (b)  The Company shall give Purchaser (i) prompt notice of any demands
for appraisal pursuant to the applicable provisions of the NYBCL received by the
Company, withdrawals of such demands, and any other instruments served pursuant
to the NYBCL and received by the Company and (ii) the opportunity to participate
in all negotiations and proceedings with respect to demands for appraisal under
the NYBCL. The Company shall not, except with the prior written consent of
Purchaser, make any payment with respect to any such demands for appraisal or
offer to settle or settle any such demands.

     Section 2.8    Surrender of Shares.  (a) Prior to the mailing of the Proxy
                    -------------------
Statement, Purchaser shall appoint a bank or trust company which is reasonably
satisfactory to the Company to act as paying agent (the "Paying Agent") for the
payment of the Merger Consideration. At the Effective Time, the Surviving
Corporation will deposit with the Paying Agent in separate trust for the benefit
of former holders of Shares sufficient funds to make all payments pursuant to
this Section 2.8. Such funds shall be invested by the Paying Agent as directed
by the Surviving Corporation. Any net profit resulting from, or interest or
income produced by, such investments will be payable to the Surviving
Corporation or as it directs.

          (b)  Promptly after the Effective Time, the Surviving Corporation
shall cause to be mailed to each record holder, as of the Effective Time, of an
outstanding certificate or certificates which immediately prior to the Effective
Time represented Shares (the "Certificates"), a form of letter of transmittal
(which shall specify that delivery shall be effected, and risk of loss and title
to the Certificates shall pass, only upon proper delivery of the Certificates to
the Paying Agent) and instructions for use in effecting the surrender of the
Certificates for payment of the Merger Consideration therefor. Upon surrender to
the Paying Agent of a Certificate, together with such letter of transmittal,
duly completed and validly executed in accordance with the instructions thereto,
and such other documents as may be required pursuant to such instructions, the
holder of such Certificate shall be entitled to receive in exchange therefor the
aggregate amount of Merger Consideration into which the number of Shares
previously represented by such Certificate or Certificates surrendered shall
have been converted pursuant to this Agreement. If any Merger Consideration is
to be remitted to a person whose name is other than that in which the
Certificate for Shares surrendered for exchange is registered, it shall be a
condition of such exchange that the Certificate so surrendered shall be properly
endorsed, with signature guaranteed, or otherwise in proper form for transfer,
and that the person requesting such 

                                      -8-
<PAGE>
 
exchange shall have paid any transfer and/or other taxes required by reason of
the remittance of Merger Consideration to a person whose name is other than that
of the registered holder of the Certificate surrendered, or the person
requesting such exchange shall have established to the satisfaction of the
Surviving Corporation that such tax either has been paid or is not applicable.
No interest shall be paid or accrued, upon the surrender of the Certificates,
for the benefit of holders of the Certificates on any Merger Consideration.

          (c)  At any time following twelve months after the Effective Time, the
Surviving Corporation shall be entitled to require the Paying Agent to deliver
to it any funds (including any interest received with respect thereto) which had
been deposited with the Paying Agent and which have not been disbursed to
holders of Certificates, and thereafter such holders shall be entitled to look
only to the Surviving Corporation (subject to abandoned property, escheat or
other similar laws) and only as general creditors thereof for payment of their
claim for Merger Consideration to which such holders may be entitled.

          (d)  Notwithstanding the provisions of Section 2.8(c), neither the
Surviving Corporation nor the Paying Agent shall be liable to any person in
respect of any Merger Consideration delivered to a public official pursuant to
any applicable abandoned property, escheat or similar law.

          (e)  Parent shall be entitled to deduct and withhold from the
consideration otherwise payable pursuant to this Agreement to any former holder
of Shares such amounts as Parent (or any affiliate thereof) is required to
deduct and withhold with respect to the making of such payment under the Code,
or any provision of any applicable state, local or foreign law, rule or
regulation. To the extent that amounts are so withheld by Parent and paid by
Parent to the applicable taxing authority, such withheld amounts shall be
treated for all purposes of this Agreement as having been paid to the former
holder of Shares in respect of which such deduction and withholding was made by
Parent.

     Section 2.9    No Further Transfer or Ownership Rights. After the Effective
                    ---------------------------------------
Time, there shall be no further transfer on the records of the Company or its
transfer agent of certificates representing Shares which have been converted
pursuant to this Agreement into the right to receive Merger Consideration, and
if such certificates are presented to the Company for transfer, they shall be
cancelled against delivery of Merger Consideration. From and after the Effective
Time, the holders of Certificates evidencing ownership of Shares outstanding
immediately prior to the Effective Time shall cease to have any rights with
respect to such Shares except as otherwise provided for herein or by applicable
law. All Merger Consideration paid upon the surrender for exchange of
Certificates representing Shares in accordance with the terms of this Article II
shall be deemed to have been issued (and paid) in full satisfaction of all
rights pertaining to the Shares theretofore represented by such Certificates.

     Section 2.10   Treatment of Options.  Prior to the Effective Time, the
                    --------------------
Board of Directors of the Company (or, if appropriate, any committee thereof)
shall adopt appropriate

                                      -9-
<PAGE>
 
resolutions and take all other actions necessary to provide that each
outstanding stock option (each "Option") heretofore granted under the Company's
1990 Nonqualified Stock Option Plan, dated June 1, 1990 (the "1990 Plan") and
the Company's 1996 Long-Term Incentive Plan (the "1996 Plan", and together with
the 1990 Plan, the "Company Stock Option Plans"), whether or not then vested or
exercisable, shall, at the Effective Time, be cancelled, and each holder thereof
shall be entitled to receive a payment in cash from the Company (subject to any
applicable withholding taxes, the "Cash Payment"), upon cancellation, equal to
the product of (x) the total number of Shares subject or related to such Option,
whether or not then vested or exercisable, and (y) the excess, if any, of the
Merger Consideration over the exercise price or purchase price, as the case may
be, per Share subject or related to such Option, each such Cash Payment to be
paid to each holder of an outstanding Option upon cancellation. Notwithstanding
the foregoing, if requested by Purchaser, the Board of Directors of the Company
(or, if appropriate, any committee thereof) shall adopt appropriate resolutions
providing for such cancellation and a cash payment equal to 101.8% of the Cash
Payment to occur, in respect of any or all Options held by certain employees of
the Company who have entered into employment agreements with the Company, on the
78th day after the date on which the Effective Time occurs. If Parent or
Purchaser and an Option holder mutually agree, such Option holder may receive in
lieu of such Cash Payment an option to acquire shares of common stock of Parent
on terms providing such Option holder with value substantially equivalent to the
value of such Cash Payment. The Company agrees that upon the exercise of any
Option it shall issue such Shares as such Option holder may be entitled to
receive upon such exercise and shall not exercise any rights it may have under
the Company Stock Option Plans or otherwise to settle such Option with a cash
payment without the written consent of Parent. As provided herein and subject to
the contractual rights of participants therein, the Company Stock Option Plans
and any Benefit Plan (or other plan, program or arrangement) providing for the
issuance or grant of any other interest in respect of the capital stock of the
Company or any subsidiary shall terminate as of the Effective Time. The Company
will take all steps necessary to ensure that none of the Company or any of its
subsidiaries is or will be bound by any Options, other options, warrants, rights
or agreements which would entitle any person, other than the current
shareholders of Purchaser or its affiliates, to acquire any capital stock of the
Surviving Corporation or any of its subsidiaries or, except as otherwise
provided in this Section 2.10, to receive any payment in respect thereof and to
cause such Options to be cancelled or cause the holders of the Options to agree
to such cancellation thereof as provided herein.

     Section 2.11   Closing.  Upon the terms and subject to the conditions
                    -------
hereof, as soon as practicable after consummation of the Offer, and to the
extent required by the NYBCL after the vote of the shareholders of the Company
in favor of the approval of the Merger and this Agreement has been obtained, the
Company and Purchaser (or Parent if appropriate) shall execute and file with the
New York Department of State the Certificate of Merger, and the parties shall
take all such other and further actions as may be required by law to make the
Merger effective. Prior to the filing referred to in this Section 2.11, a
closing (the "Closing") will be held at the offices of Dechert Price & Rhoads,
4000 Bell Atlantic Tower, 1717 Arch Street, Philadelphia, PA

                                  ARTICLE III

                 REPRESENTATIONS AND WARRANTIES OF THE COMPANY

          Except as set forth in the Company Disclosure Schedule where the
relevance of such disclosure to the applicable representation and warranty is
readily apparent from such disclosure, the Company hereby represents and
warrants to Parent and Purchaser as follows:

     Section 3.1    Organization and Qualification.
                    ------------------------------

          (a)  The Company is a corporation duly organized, validly existing and
in good standing under the laws of the State of New York and has the requisite
corporate power and authority necessary to enable it to own, lease and operate
its properties and assets and to carry on its business as it is now being
conducted. The Company is duly qualified as a foreign corporation or licensed to
do business, and is in good standing, in each jurisdiction where the character
of its properties owned or leased or the nature of its activities makes such
qualification or licensing necessary, except where the failure to be so
qualified or licensed and in good standing, individually or in the aggregate,
has not had and would not reasonably be expected to have a Material Adverse
Effect on the Company.

          (b)  The only subsidiaries of the Company are those named in Exhibit
21 to the Company's Annual Report on Form 10-K for the fiscal year ended
February 28, 1998 or set forth on Section 3.1(b) of the Company Disclosure
Schedule. Each Significant Subsidiary of the Company is a corporation duly
organized, validly existing and in good standing under the laws of its
jurisdiction of incorporation and has the requisite corporate power and
authority necessary to enable it to own, lease and operate its properties and
assets and to carry on its business as it is now being conducted. Each other
subsidiary of the Company is a corporation duly organized, validly existing and
in good standing under the laws of its jurisdiction of incorporation and has the
requisite power and authority necessary to enable it to own, lease and operate
its property and assets and to carry on its business as it is now being
conducted, except where the failure to be so organized, existing or in good
standing or to have such power and authority would not, individually or in the
aggregate, reasonably be expected to have a Material Adverse Effect on the
Company. Each subsidiary of the Company is duly qualified as a foreign
corporation or licensed to do business, and is in good standing, in each
jurisdiction where the character of its properties owned or leased or the nature
of its activities makes such qualification or licensing necessary, except where
the failure to be so qualified or licensed or in good standing, individually or
in the aggregate, has not had and would not reasonably be expected to have a
Material Adverse Effect on the Company. As used in this Agreement, "Significant
Subsidiary" shall have the meaning set forth in Rule 1-02 of Regulation S-X of
the SEC.

                                      -11-
<PAGE>
 
          (c)  All of the outstanding shares of capital stock of each such
subsidiary have been validly issued and are fully paid and non-assessable and,
except as set forth in Section 3.1(b) of the Company Disclosure Schedule, are
owned by the Company, by another wholly owned subsidiary of the Company or by
the Company and another such wholly owned subsidiary, free and clear of all
pledges, claims, equities, options, liens, charges, rights of first refusal,
"tag" or "drag" along rights, encumbrances and security interests of any kind or
nature whatsoever (collectively, "Liens"). Except for the capital stock of its
subsidiaries, the Company does not own, directly or indirectly, any capital
stock or other ownership interest in any corporation, partnership, limited
liability company, joint venture or other entity. The Company has delivered to
Parent complete and correct copies of its Certificate of Incorporation and
Bylaws and the comparable charters and bylaws or other organizational documents
of its subsidiaries, in each case as amended to the date of this Agreement.

     Section 3.2    Capitalization.
                    --------------

          (a)  The authorized capital stock of the Company consists of
35,000,000 Shares. All of the issued and outstanding Shares have been duly
authorized and validly issued and are fully paid and nonassessable and are not
subject to preemptive rights. As of the date hereof, 12,544,682 Shares were
issued and outstanding, 1,313,364 Shares were reserved for issuance pursuant to
outstanding Options of a like number issued under the Company Stock Option
Plans. Such Shares reserved for issuance under the Company Stock Option Plans
have not been issued and will not be issued prior to the Effective Time, and no
commitment has been or will be made for their issuance, other than under the
Options described in the preceding sentence and issued and outstanding under the
Company Stock Option Plans as of the date of this Agreement.

          (b)  Except as otherwise provided in Section 2.10 of this Agreement,
at the Effective Time, each Option shall be cancelled and the holder thereof
shall not be entitled to receive any consideration therefor other than the cash
payments provided by Section 2.10 of this Agreement. Section 3.2(b) of the
Company Disclosure Schedule sets forth the exercise prices and number of Shares
in respect of outstanding Options under the Company Stock Option Plans. There
are no bonds, debentures, notes or other indebtedness of the Company having the
right to vote (or convertible into, or exchangeable for, securities having the
right to vote) on any matters on which shareholders of the Company may vote
("Voting Company Debt"). Except as set forth above, there are no outstanding
securities, options, warrants, calls, rights, convertible or exchangeable
securities, "phantom" stock rights, stock appreciation rights, stock-based
performance units, commitments, agreements, arrangements or undertakings of any
kind to which the Company or any of its subsidiaries is a party or by which any
of them is bound obligating the Company or any of its subsidiaries to issue,
deliver or sell, or cause to be issued, delivered or sold, additional shares of
capital stock or other voting securities of the Company or any of its
subsidiaries or obligating the Company or any of its subsidiaries to issue,
grant, extend or enter into any such security, option, warrant, call, right,
unit, commitment, agreement, arrangement or undertaking. There are not any
outstanding contractual obligations of the Company or any of its subsidiaries to
repurchase, redeem or otherwise acquire, or providing preemptive or registration

                                      -12-
<PAGE>
 
rights with respect to, any shares of, or any outstanding options, warrants or
rights of any kind to acquire any shares of, or any outstanding securities that
are convertible into or exchangeable for any shares of, capital stock of the
Company or any of its subsidiaries. The Company and its subsidiaries do not have
outstanding any loans to any person in respect of the purchase of securities
issued by the Company and its subsidiaries.

          (c)  There are no voting trusts, proxies or other agreements,
commitments or understandings of any character to which the Company or any of
its subsidiaries is a party or by which the Company or any of its subsidiaries
is bound with respect to the voting of any shares of capital stock of the
Company or any of its subsidiaries or with respect to the registration of the
offering, sale or delivery of any shares of capital stock of the Company or any
of its subsidiaries under the Securities Act of 1933, as amended (the
"Securities Act").

     Section 3.3    Authority Relative to this Agreement.  (a) The Company has
                    ------------------------------------
all requisite corporate power and authority to execute and deliver this
Agreement, to perform its obligations hereunder, and to consummate the
Transactions (subject to the Company Shareholder Approval (as hereinafter
defined) with respect to the Merger). The execution and delivery of this
Agreement and the performance of its obligations hereunder and the consummation
by the Company of the Transactions have been duly and validly authorized by the
Board of Directors of the Company and no other corporate proceedings on the part
of the Company are necessary to authorize this Agreement or to consummate the
Transactions (other than the Company Shareholder Approval and the filing and
recordation of appropriate merger documents as required by the NYBCL). This
Agreement has been duly and validly executed and delivered by the Company, and,
assuming this Agreement constitutes a valid and binding obligation of Parent and
Purchaser, this Agreement constitutes a valid and binding agreement of the
Company, enforceable against the Company in accordance with its terms.

          (b)  The only vote of holders of any class or series of capital stock
of the Company or any of its subsidiaries necessary to adopt or approve this
Agreement and the Merger is the adoption of this Agreement by the holders of 
two-thirds of the outstanding Shares (the "Company Shareholder Approval"),
subject to Section 6.9(d). The affirmative vote of the holders of any capital
stock of the Company or any of its subsidiaries, or any of them, is not
necessary to consummate the Offer or any transaction contemplated by this
Agreement other than as set forth in the preceding sentence.

     Section 3.4    Absence of Certain Changes.  Except as disclosed in the
                    --------------------------
Company's filings and reports under the Exchange Act filed and publicly
available prior to the date of this Agreement (the "Filed Company SEC
Documents") or as set forth in Section 3.4 of the Company Disclosure Schedule,
since August 31, 1998, the Company and its subsidiaries have conducted their
business only in the ordinary course in all material respects, and during such
period there has not been any event, change, effect or development that,

have a Material Adverse Effect on the Company. Except as disclosed in the Filed
Company SEC Documents or as set forth in Section 3.4 of the Company

                                      -13-
<PAGE>
 
Disclosure Schedule, since August 31, 1998 there has not been (a) any
declaration, setting aside or payment of any dividend (other than the

excess of $0.14 per Share) or other distribution in respect of the capital stock
of the Company or any redemption or other acquisition by the Company of any
capital stock of the Company; (b) any entry into any agreement, commitment or
transaction by the Company or any of its subsidiaries which is material to the
Company and its subsidiaries taken as a whole, except agreements, commitments or
transactions in the ordinary course of business; (c) any split, combination or
reclassification of the Company's capital stock or of any other equity interests
in the Company, or any issuance or the authorization of any issuance of any
other securities in respect of, in lieu of or in substitution for shares of its
capital stock or of any other equity interests in the Company; (d)(i) any
granting by the Company or any of its subsidiaries to any officer, director or
key employee of the Company or any of its subsidiaries of any increase in
compensation, except in the ordinary course of business or as was required under
employment agreements in effect as of the date of the most recent audited
financial statements included in the Filed Company SEC Documents, (ii) any
granting by the Company or any of its subsidiaries to any such officer, director
or key employee of any increase in severance or termination pay, except as was
required under employment, severance or termination agreements in effect as of
the date of the most recent audited financial statements included in the Filed
Company SEC Documents or (iii) any entry by the Company or any of its
subsidiaries into any employment, severance or termination agreement with any
such officer, director or key employee; (e) any damage, destruction or loss,
whether or not covered by insurance, that, individually or in the aggregate, has
had or would reasonably be expected to have a Material Adverse Effect on the
Company; or (f) any change in accounting methods, principles or practices by the
Company or any subsidiary materially affecting the consolidated assets,
liabilities, results of operations or business of the Company, except insofar as
may have been required by a change in generally accepted accounting principles.

     Section 3.5    Reports.  Since March 1, 1996, the Company has timely filed
                    -------
all required forms, reports and documents with the SEC required to be filed by
it pursuant to the federal securities laws and the SEC rules and regulations
thereunder (collectively, the "Company SEC Documents"), all of which have
complied as of their respective filing dates in all material respects with all
applicable requirements of the Securities Act and the Exchange Act, and the
rules promulgated thereunder. The Company has delivered copies of all such
forms, reports or documents to Parent. None of such forms, reports or documents
at the time filed (or at the time amended), contained any untrue statement of a
material fact or omitted to state a material fact required to be stated therein
or necessary in order to make the statements therein, in light of the
circumstances under which they were made, not misleading. The financial
statements of the Company included in the Company SEC Documents comply as to
form in all material respects with applicable accounting requirements and the
published rules and regulations of the SEC with respect thereto, have been
prepared in accordance with generally accepted accounting principles (except, in
the case of unaudited statements, as permitted by Form 10-Q of the SEC) applied
on a consistent basis during the periods involved (except as may be indicated in
the notes thereto) and fairly present the consolidated financial position of the
Company and its consolidated subsidiaries

                                      -14-
<PAGE>
 
as of the dates thereof and the consolidated results of their operations and
cash flows for the periods then ended (and include, in the case of any unaudited
interim financial statements, reasonable accruals for normal year-end
adjustments). No subsidiaries of the Company are required to file periodic
reports with the SEC under the Exchange Act.

     Section 3.6    Proxy Statement.  If a Proxy Statement is required for the
                    ---------------
consummation of the Merger under applicable law, the Proxy Statement will comply
in all material respects with the Exchange Act, except that no representation is
made by the Company with respect to information supplied by or on behalf of
Parent or any affiliate of Parent specifically for inclusion in the Proxy
Statement. None of the information supplied by the Company specifically for
inclusion in the Proxy Statement shall, at the time the Proxy Statement is
mailed or at the time of the Shareholder Meeting or at the Effective Time,
contain any untrue statement of a material fact or omit to state any material
fact required to be stated therein or necessary in order to make the statements
therein, in light of the circumstances under which they were made, not
misleading; provided, however, that the Company makes no representation or
warranty as to any of the information relating to and supplied by or on behalf
of Parent and Purchaser specifically for inclusion in the Proxy Statement. The
letter to shareholders, notice of meeting, proxy statement and form of proxy, or
the information statement, as the case may be, to be distributed to shareholders
in connection with the Merger, or any schedule required to be filed with the SEC
in connection therewith, together with any amendments or supplements thereto,
are collectively referred to herein as the "Proxy Statement." If, at any time
prior to the Effective Time, any event relating to the Company or any of its
affiliates, officers or directors is discovered by the Company that shall be set
forth in a supplement to the Proxy Statement, the Company will promptly inform
Parent and Purchaser and prepare, file and disseminate such supplement as may be
required by applicable law.

     Section 3.7    Consents and Approvals; No Violation.  Subject to obtaining
                    ------------------------------------
the Company Shareholder Approval (if required under the NYBCL) and the taking of
the actions described in the immediately succeeding sentence, the execution,
delivery and performance of this Agreement do not, and the consummation of the
Transactions (including the changes in ownership of Shares or the composition of
the Board of Directors of the Company) and compliance with the provisions of
this Agreement will not, conflict with, or result in any violation of, or
default (with or without notice or lapse to time, or both) under, or give rise
to a right of termination, cancellation or acceleration of any obligation or
loss of a material benefit under, or result in the creation of any Lien upon any
of the material properties or assets of the Company or any of its subsidiaries
under, or result in the termination of, or require that any consent be obtained
or any notice be given with respect to, (i) the Certificate of Incorporation or
Bylaws of the Company or the comparable charter or organizational documents of
any of its subsidiaries, (ii) any loan or credit agreement note, bond, mortgage,
indenture, lease, license or other agreement, instrument, Contract or Permit
applicable to the Company or any of its subsidiaries or their respective
properties or assets, (iii) any judgment, order, writ, injunction, decree, law,
statute, ordinance, rule or regulation applicable to the Company or any of its
subsidiaries

<PAGE>
 
is a party, other than, in the case of clauses (ii), (iii) or (iv), any such
conflicts, violations, defaults, rights, Liens, losses of a material benefit,
consents or notices that, individually or in the aggregate, have not and would
not reasonably be expected to have a Material Adverse Effect on the Company. No
consent, approval, order or authorization of, or registration, declaration or
filing with, any Federal, state or local government or any court, administrative
or regulatory agency or commission or other governmental authority or agency,
domestic or foreign (a "Governmental Entity") is required by the Company or any
of its subsidiaries in connection with the execution and delivery of this
Agreement by the Company or the consummation by the Company of the Transactions,
except for (i) the filing of a premerger notification and report form by the
Company under the HSR Act (as hereinafter defined), the filing of a notice with
the German Federal Cartel Office under the German Act Against Restraints of
Competition (the "GWB Act") or in connection with any other foreign antitrust or
competition laws, (ii) the filing with the SEC of (x) the Schedule 14D-9, (y) if
required, the Proxy Statement relating to the approval by the Company's
shareholders of this Agreement and (z) such reports under Section 13(a) of the
Exchange Act as may be required in connection with this Agreement and the
transactions contemplated by this Agreement, (iii) the filing of the Certificate
of Merger pursuant to the NYBCL and (iv) such other consents, approvals, orders,
authorizations, registrations, declarations and filings the failure of which to
be obtained or made, individually or in the aggregate, has not had and would not
reasonably be expected to have a Material Adverse Effect on the Company or where
the requirement to obtain such consent, approval, authorization or permit, or to
make such filing or notification arises solely from the regulatory status of
Parent or Purchaser.

     Section 3.8   Brokerage Fees and Commissions. Except for those fees and
                   ------------------------------
expenses payable to The Beacon Group Capital Services LLC (the "Company
Financial Advisor") and Eugene Nadel pursuant to the letter agreement, dated
September 24, 1998, no person is entitled to receive any investment banking,
brokerage or finder's fee or commission in connection with this Agreement or the
Transactions based upon arrangements made by or on behalf of the Company or any
of its subsidiaries or by any affiliate of the Company or any of its
subsidiaries. A copy of the above agreement has previously been delivered to
Parent.

     Section 3.9   Schedule 14D-9; Offer Documents.  Neither the Schedule 14D-9,
                   ------------------------------- 
any other document required to be filed by the Company with the SEC in
connection with the Transactions, nor any information supplied by the Company in
writing specifically for inclusion in the Offer Documents or the Schedule 14D-1
shall, at the respective times the Schedule 14D-9, any such of other filings by
the Company, the Schedule 14D-1, the Offer Documents or any amendments or
supplements thereto are filed with the SEC or are first published, sent or given
to stockholders of the Company, as the case may be, contain any untrue statement
of a material fact or omit to state any material fact required to be stated
therein or necessary in order to make the statements therein, in light of the
circumstances under which they are made, not misleading. The Schedule 14D-9 and
any other document required to be filed by the Company with the SEC in
connection with the Transactions will comply as to form in all material respects
with the requirements of the Exchange Act and the rules and regulations
thereunder. Notwithstanding the 

                                      -16-
<PAGE>
 
foregoing, no representation or warranty is made by the Company with respect to
statements made or incorporated by reference therein based on information
supplied by or on behalf of Parent or Purchaser specifically for inclusion or
incorporation by reference therein.

     Section 3.10   Litigation.  Except as disclosed in the Company SEC
                    ----------
Documents, there is no claim, suit, action or proceeding (including arbitration
proceedings) pending or, to the knowledge of the Company, threatened against the
Company or any of its subsidiaries that, individually or in the aggregate, has
had or would reasonably be expected to have a Material Adverse Effect on the
Company, nor is there any judgment, decree, injunction, rule or order of any
Governmental Entity or arbitrator outstanding against the Company or any of its
subsidiaries which, individually or in the aggregate, has had or would
reasonably be expected to have a Material Adverse Effect on the Company.

     Section 3.11   Insurance.  The Company and its subsidiaries maintain
                    ---------
policies of fire and casualty, liability and other forms of insurance in such
amounts, with such deductibles and against such risks and losses as are, in the
Company's judgment, reasonable for the assets and properties of the Company and
its subsidiaries and customary in the Company's industry. As of the date of this
Agreement, except as set forth in Section 3.11 of the Company's Disclosure
Schedule, all material insurance policies are in full force and effect, all
premiums due and payable thereon have been paid, and no notice of cancellation
or termination has been received with respect to any such policy.

     Section 3.12   ERISA Compliance. (a) Section 3.12(a) of the Company
                    ----------------
Disclosure Schedule sets forth a complete list of all "employee benefit plans"
(as defined in Section 3(3) of the Employee Retirement Income Security Act of
1974, as amended ("ERISA")), and each material employment contract, bonus,
pension, profit sharing, deferred compensation, incentive compensation, excess
benefit, stock, stock option, severance, termination pay, change in control or
other material employee benefit plan, program or arrangement, whether written or
unwritten, qualified or unqualified, funded or unfunded, foreign or domestic
currently maintained, or contributed to, or required to be maintained or
contributed to, by the Company or any subsidiary for the benefit of any current
or former employees, officers or directors of the Company or any of its
subsidiaries or with respect to which the Company or any of its subsidiaries has
any liability (collectively, the "Benefit Plans"), except for Benefit Plans that
are maintained or contributed to by a subsidiary other than a Specified
Subsidiary and which the executive officers of the Company located at the
Company's headquarters do not have actual knowledge of as of the date of this
Agreement. For purposes of the preceding sentence, an employment agreement shall
be deemed material if the Company or a subsidiary may not terminate the contract
or the employment of the individual who is a party to the contract without
incurring a liability in excess of $100,000, and an employee benefit plan,
program or arrangement will be material if the aggregate annual cost associated
therewith exceeds $250,000. As used herein, "Specified Subsidiary" shall mean
LeaRonal (UK) plc, LeaRonal AG and LeaRonal (S.E. Asia) Ltd.

                                      -17-
<PAGE>
 
          (b)  Each Benefit Plan has been maintained, operated and administered
in all material respects in accordance with its terms. The Company, each
subsidiary and all the Benefit Plans are all in compliance in all material
respects with the applicable provisions of ERISA, the Internal Revenue Code of
1986, as amended (the "Code") and any other applicable law, rule or regulation,
domestic or foreign.

          (c)  No event has occurred and, to the knowledge of the Company, there
exists no condition or set of circumstances in connection with which the Company
or any subsidiary could be subject to any liability under the terms of any
Benefit Plan, or under ERISA, or, with respect to any Benefit Plan, under ERISA,
the Code or any other applicable law, rule or regulation, domestic or foreign,
other than any condition or set of circumstances that, individually or in the
aggregate, has not had and would not reasonably be expected to have a Material
Adverse Effect on the Company. Neither the Company nor any subsidiary has
incurred or would reasonably be expected to incur any liability in respect of
any employee benefit plan maintained by any person other than the Company or a
subsidiary which would be treated as a single employer with the Company or a
subsidiary under Section 414(b) or (c) of the Code.

          (d)  The Benefit Plans which are "employee pension benefit plans"
within the meaning of Section 3(2) of ERISA and which are intended to meet the
qualification requirements of Section 401(a) of the Code (each a "Pension Plan")
now meet, and at all times since their inception have met the requirements for
such qualification, and the related trusts are now, and at all times since their
inception have been, exempt from taxation under Section 501(a) of the Code. All
Pension Plans have received determination letters from the IRS to the effect
that such Pension Plans are qualified and the related trust are exempt from
federal income taxes and no determination letter with respect to any Pension
Plan has been revoked nor, to the best knowledge of the Company is there any
reason for such revocation, nor has any Pension Plan been amended since the date
of its most recent determination letter in any respect which would adversely
affect its qualification.

          (e)  No Benefit Plan is now or at any time has been subject to Part 3,
Subtitle B of Title I of ERISA or Title IV of ERISA.

          (f)  There are no investigations, audits, actions, suits or claims
pending (other than routine claims for benefits) or, to the knowledge of the
Company, threatened against, or with respect to, any Benefit Plan or its assets,
any fiduciary thereof or service provider thereto nor to the knowledge of the
Company is there any reasonable basis for any such claim, suit or proceeding
that, individually or in the aggregate, has had or would reasonably be expected
to have a Material Adverse Effect on the Company.

          (g)  To the knowledge of the Company, there is no matter pending
(other than routine qualification determination filings) with respect to any
Benefit Plan before the IRS, the Department of Labor or the Pension Benefit
Guaranty Corporation ("PBGC").

of Parent and Purchaser is duly qualified as a foreign corporation or licensed
to do business, and is in good standing, in each jurisdiction where the
character of its properties owned or leased or the nature of its activities
makes such qualification or licensing necessary, except where the failure to be

to prevent or materially delay the consummation of the Offer or the Merger.

     Section 4.2   Authority Relative to this Agreement. Each of Parent and
                   ------------------------------------
Purchaser has all requisite corporate power and authority to execute and deliver

Agreement and the performance of their respective obligations hereunder, and the
consummation by Parent and Purchaser of the Transactions have been duly and
validly authorized by the respective Boards of Directors of Parent and
Purchaser, and the shareholder of Purchaser, and no other corporate proceedings
on the part of Parent or Purchaser are necessary to authorize this Agreement, or
commence the Offer or to consummate the Transactions (including the Offer) other
than filing and recordation of appropriate merger 

                                      -25-
<PAGE>
 
documents as required by the NYBCL. This Agreement has been duly and validly
executed and delivered by each of Parent and Purchaser and, assuming this
Agreement constitutes a valid and binding obligation of the Company, this
Agreement constitutes a valid and binding agreement of each of Parent and
Purchaser, enforceable against each of Parent and Purchaser in accordance with
its terms.

     Section 4.3   Proxy Statement. None of the information supplied in writing
                   ---------------

mailed, at the time of the Shareholder Meeting or at the Effective Time, contain
any untrue statement of a material fact or omit to state any material fact
required to be stated therein or necessary in order to make the statements
therein, in light of the circumstances under which they were made, not
misleading; provided, however, that Parent and Purchaser make no representation
or warranty as to any of the information supplied by or on behalf of the Company
specifically for inclusion in the Proxy Statement. If, at any time prior to the
Effective Time, any event relating to Parent or any of its affiliates, officers
or directors is discovered by Parent that should be set forth in a supplement to

                   ------------------------------------ 
of the actions described in the immediately succeeding sentence, the execution
and delivery of this Agreement do not, and the consummation of the Transactions
will not, conflict with, or result in any violation of, or default (with or
without notice or lapse of time, or both) under, or give rise to a right of
termination, cancellation or acceleration of any obligation or to loss of a
material benefit under, or result in the creation of any Lien upon any of the
material properties or assets of Parent under (i) the certificate of
incorporation or bylaws of Parent or Purchaser, (ii) any loan or credit
agreement, note, bond, indenture, lease or other agreement, instrument or Permit
applicable to Parent or Purchaser or their respective properties or assets,
(iii) any judgment, order, writ, injunction, decree, law, statute, ordinance,
rule or regulation applicable to Parent or Purchaser or their respective
properties or assets, other than, in the case of clause (ii) and (iii), any such
conflicts, violations, defaults, rights or Liens that individually or in the
aggregate would not (x) impair in any material respect the ability of Parent and
Purchaser to perform their respective obligation under this Agreement or (y)
prevent or impede the consummation of any of the Transactions. No consent,
approval, order or authorization of, or registration, declaration or filing
with, any Governmental Entity or any other person is required by Parent or

such consent, approval, authorization or permit, or to make any such filing or
notification, would not prevent or delay consummation of the Offer or the Merger
or would not otherwise prevent Parent from performing its obligations under this
Agreement or where the requirement to obtain such consent, approval,
authorization or permit, or to make such filing or notification arises from the
regulatory status of the Company or its subsidiaries.

acceptance for purchase by Purchaser of Shares pursuant to the Offer and (ii)

     Section 6.5    Indemnification of Directors and Officers.
                    -----------------------------------------

          (a)    Purchaser agrees that all rights to indemnification for acts or
omissions occurring prior to the Effective Time existing as of the date hereof
in favor of the current or former directors or officers of the Company and its
subsidiaries as provided in their respective certificates of incorporation or
bylaws shall survive the Merger and shall continue in full force and effect in
accordance with their terms for a period of six years from the Effective Time.
Parent shall cause to be maintained, if available, for a period of six years
from the Effective Time the Company's current directors' and officers' insurance
and indemnification policy (the "D&O Insurance") (provided that Parent may
substitute therefor policies or financial guarantees with the same carriers or
other obligors as insure Parent's directors and officers of at least the same
coverage and amounts containing terms and conditions which are substantially
similar to the existing D&O Insurance) to the extent that such insurance
policies provide coverage for events occurring prior to the Effective Time for
all persons who are directors and officers of the Company on the date of this
Agreement, so long as the annual premium to be paid by the Company after the
date of this Agreement for such D&O Insurance during such six-year period would
not exceed 200% of the current annual premium therefor. If, during such six-year
period, such insurance coverage cannot be obtained at all or can only be
obtained for an amount in excess of 200% of the current annual premium therefor,
Parent shall use all reasonable efforts to cause to be obtained as much D&O
Insurance as can be obtained for an amount equal to 200% of the current annual
premium therefor, on terms and conditions substantially similar to the existing
D&O Insurance.

          (b)    If any claim or claims shall, subsequent to the Effective Time
and within six years thereafter, be made in writing against any present or
former director or officer of the Company based on or arising out of the
services of such person prior to the Effective Time in the capacity of such
person as a director or officer of the Company (and such director or officer
shall have given Parent written notice of such claim or claims within such six
year period), the provisions of subsection (a) of this Section respecting the
rights to indemnify the current or 

                                      -35-
<PAGE>
 
former directors or officers under the certificate of incorporation and bylaws
of the Company and its subsidiaries shall continue in effect until the final
disposition of all such claims.

          (c)    The provisions of this Section 6.5 are intended to be for the
benefit of, and shall be enforceable by, each person entitled to indemnification
hereunder and the heirs and representatives of such person.

     Section 6.6    Event Notices and Other Actions. (a) From and after the date
                    -------------------------------
of this Agreement until the Effective Time, each party hereto shall promptly
notify the other parties hereto of (i) the occurrence or nonoccurrence of any
event, the occurrence or nonoccurrence of which has resulted in, or would
reasonably be expected to result in, any condition to the Offer set forth in
Annex A, or any condition to the Merger set forth in Article VII, not being
satisfied, (ii) the failure of such party to comply with any covenant or
agreement to be complied with by it pursuant to this Agreement which has
resulted in, or would reasonably be expected to result in, any condition to the
Offer set forth in Annex A, or any condition to the Merger set forth in Article
VII, not being satisfied and (iii) any breach of any representation or warranty
made by it contained in this Agreement (excluding for this purpose any
materiality qualifications contained therein) that would be reasonably likely to
have a Material Adverse Effect on the breaching party. No delivery of any notice
pursuant to this Section 6.6(a) shall cure any breach of any representation or

Effective Time, and the provision in any other Benefit Plan providing for the
potential issuance, transfer or grant of any capital stock of the Company or any
of its subsidiaries or any interest, or release of restrictions in respect of

security or any participant in the Company Stock Option Plans or other Benefit
Plan shall have any right thereunder to acquire any capital stock of the Company
or any of its subsidiaries or the Surviving Corporation, except as provided in

entitled thereto in accordance with the terms of such 

                                      -37-

                     -------- ----
period has not closed as of the Effective Time, the amount to be paid shall be a
pro rata portion of the otherwise payable amount (determined, where performance

Company and its subsidiaries who remain employees of the Surviving Corporation
after the Effective Time that are, in the aggregate, no less favorable than
those provided by the Company and its subsidiaries immediately prior to the
Effective Time. From and after the Effective Time, for purposes of determining

Parent or such subsidiary; provided that Parent and Purchaser shall have no
                           -------- ----

          (a)    To the extent required by applicable law, the Company shall
promptly take all action necessary in accordance with the NYBCL and its
Certificate of Incorporation and Bylaws to convene a meeting of the Company's
shareholders (the "Shareholder Meeting") to consider and vote on the Merger and
this Agreement. At the Shareholder Meeting, all of the Shares then owned by
Parent, Purchaser or any other subsidiary of Parent shall be voted to approve
the Merger and this Agreement. The Board of Directors of the Company shall
recommend that the Company's shareholders vote to approve the Merger and this
Agreement if such vote is sought, shall use its best efforts to solicit from
shareholders of the Company proxies in favor of the Merger and shall take all
other action in its judgment necessary and appropriate to secure the vote of
shareholders required by the NYBCL to effect the Merger.

          (b)    Parent and Purchaser shall not, and they shall cause their
subsidiaries not to, sell, transfer, assign, encumber or otherwise dispose of
the Shares acquired pursuant to the Offer or otherwise prior to the Shareholder
Meeting; provided, however, that this Section 6.9(b) shall not apply to the
         --------  ------- 
sale, transfer, assignment, encumbrance or other disposition of any or all such
Shares in transactions involving solely Parent, Purchaser and/or one or more of
their wholly owned subsidiaries.

          (c)    Notwithstanding the foregoing, in the event that Purchaser
shall acquire at least 90% of the then outstanding Shares, the parties hereto
agree, at the request of Purchaser, to take all necessary and appropriate action
to cause the Merger to become effective, in accordance

                                      -38-
<PAGE>
 
with Section 905 of the NYBCL, as soon as reasonably practicable after such
acquisition, without a meeting of the shareholders of the Company.

          (d)    In the event that Purchaser reduces the Minimum Condition as
permitted by Section 1.1(b) and accepts for payment Shares tendered pursuant to
the Offer, which Shares are less than two-thirds of the Fully Diluted Shares,
the Company shall convene a meeting of its shareholders, or take or permit
Purchaser to take such action as may be necessary or desirable, to amend the
Certificate of Incorporation to provide that the requisite vote of the Company's
shareholders on any merger or consolidation (including the Merger) shall be a
majority of the Shares outstanding. At such meeting, all of the Shares then
owned by Parent, Purchaser or any other subsidiary of Parent shall be voted to
approve such amendment.

     Section 6.10   Proxy Statement.  If required under applicable law, the
                    ---------------
Company and Parent shall prepare the Proxy Statement, file it with the SEC under
the Exchange Act as promptly as practicable after Purchaser purchases Shares
pursuant to the Offer, and use all reasonable efforts to have it cleared by the
SEC. As promptly as practicable after the Proxy Statement has been cleared by
the SEC, the Company shall mail the Proxy Statement to the shareholders of the
Company as of the record date for the Shareholder Meeting.

     Section 6.11   Public Announcements.  Parent and the Company shall to the
                    --------------------
fullest extent practicable consult with each other before issuing any press
release or otherwise making any public statement with respect to the Offer, the
Merger and the other Transactions and shall not issue any such press release or
make any such public statement prior to such consultation, except as may be
required by law.

Agreement may be amended by action taken by or on behalf of the Boards of
Directors of the Company, Parent and Purchaser at any time before or after
approval of this Agreement by the shareholders of the Company but, after any
such shareholder approval, no amendment shall be made that by law requires the
further approval of such shareholders without the approval of such shareholders.
This Agreement may not be amended except by an instrument in writing signed on

shareholders of the Company, no extensions or waivers shall be made that by law
require further approval by such shareholders without the approval of such

                                 MISCELLANEOUS

     Section 9.1    Non-Survival of Representations and Warranties.  None of the
                    ----------------------------------------------
representations and warranties made in this Agreement shall survive after the
Effective Time. This Section 9.1 shall not limit any covenant or agreement of
the parties hereto which by its terms contemplates performance after the
Effective Time.

     Section 9.2    Entire Agreement; Assignment.  This Agreement (including the
                    ----------------------------
Company Disclosure Schedule), the Tender and Option Agreement, the Other
Agreements and, to the extent contemplated in Section 6.3, the Confidentiality
Agreement, (a) constitute the entire agreement among the parties with respect to
the subject matter hereof and supersede all other prior agreements and
understandings, both written and oral, among the parties or any of them with
respect to the subject matter hereof and (b) shall not be assigned by operation
of law or otherwise, provided that Parent or Purchaser may assign any of their
rights and obligations to any direct or indirect wholly owned subsidiary of
Parent, but no such assignment shall relieve Parent 

                                      -43-
<PAGE>
 
or Purchaser of its obligations hereunder. Any of Parent, Purchaser or any
direct or indirect wholly owned subsidiary of Parent may purchase Shares under
the Offer. Any attempted assignment in violation of this Section 9.2 shall be
void. Subject to the preceding sentences, this Agreement will be binding upon,
inure to the benefit of, and be enforceable by, the parties and their respective
successors and assigns.

     Section 9.3    Enforcement of the Agreement. The parties agree that
                    ----------------------------
irreparable damage would occur to the other parties hereto in the event that any
of the provisions of this Agreement were not performed by the parties hereto in
accordance with their specific terms or were otherwise breached. It is
accordingly agreed that each party shall be entitled to an injunction or
injunctions to prevent breaches of this Agreement and to enforce specifically
the terms and provisions hereof in any federal or state court of the United
States or any state having jurisdiction, this being in addition to any other
remedy to which they are entitled at law or in equity including those set forth
in Section 8.3 of this Agreement. Each party further agrees to waive any
requirement for the securing or posting of any bond in connection with the
obtaining of any such injunctive or other equitable relief.

     Section 9.4    Severability.  If any term or other provision of this
                    ------------
Agreement is invalid, illegal or incapable of being enforced by any rule of law
or public policy, all other conditions and provisions of this Agreement shall
nevertheless remain in full force and effect so long as the economic and legal
substance of the transactions contemplated hereby is not affected in any manner
materially adverse to any party. Upon such determination that any term or other
provision is invalid, illegal or incapable of being enforced, the parties hereto
shall negotiate in good faith to modify this Agreement so as to effect the
original intent of the parties as closely as possible in an acceptable manner.
The invalidity or unenforceability of any provision of this Agreement shall not
affect the validity or enforceability of any other provisions of this Agreement,
which shall remain in full force and effect.

     Section 9.5    Notices.  All notices and other communications hereunder
                    -------

shall have (i) withdrawn, or modified, amended or changed (including by
amendment of the Schedule 14D-9), in a manner adverse to Parent or Purchaser,
its approval or recommendation of the Offer, the Merger Agreement and the Merger
or any of the other Transactions, (ii) approved or recommended to the Company's
stockholders an Acquisition Proposal or any other acquisition of Shares other
than the Offer and the Merger or (iii) adopted any resolution to effect any of
the foregoing;

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

          (i)  any person (which includes a "person" as such term is defined in
Section 13(d)(3) of the Exchange Act) other than Parent, Purchaser, any of their
affiliates, or any group of which any of them is a member, shall have acquired
beneficial ownership of more than 20 percent of the Shares or shall have
consummated or entered into a definitive agreement or an agreement in principle
to consummate an Acquisition Proposal;

     which, in the sole judgment of Purchaser, in any such case, makes it
inadvisable to proceed with the Offer or with such acceptance for payment,
purchase of, or payment for Shares.

     The foregoing conditions are for the sole benefit of Purchaser and Parent
and may, subject to the terms of the Merger Agreement, be waived by Purchaser or
Parent, in whole or in part, at any time and from time to time, in the sole
discretion of Purchaser or Parent. The failure by Purchaser or Parent or any of
their respective affiliates at any time to exercise any of the foregoing rights
will not be deemed a waiver of any right, the waiver of any such right with
respect to particular facts and circumstances shall not be deemed a waiver with
respect to any other facts and circumstances and each right will be deemed an
ongoing right which may be asserted at any time and from time to time.

Confidentiality Agreement, dated as of October 21, 1998, by and between Parent 
and the Company.

                           CONFIDENTIALITY AGREEMENT

     In connection with the consideration of a possible transaction between each
of the parties that have signed this agreement and/or its respective
subsidiaries, affiliates or divisions (each such party being hereinafter
referred to, collectively with such subsidiaries, affiliates and divisions, as a
"Company"), each Company (in its capacity as a provider of information hereunder
being referred to as a "Provider") is prepared to make available to the other
Company (in its capacity as a recipient of information hereunder being referred
to as a "Recipient") certain information concerning the business, financial
condition, operations, assets and liabilities of the Provider. As a condition to
such information being provided to each Recipient and its Recipient
Representatives (as hereinafter defined), each Recipient agrees to treat any
information concerning the Provider (whether prepared by the Provider, such
Provider's Representatives (as hereinafter defined) or otherwise and
irrespective of the form of communication) which is furnished to the Recipient
or such Recipient's Representatives now or in the future by or on behalf of the
Provider (herein collectively referred to, with respect to information furnished
by or on behalf of either Company in its capacity as a Provider to the other
Company in its capacity as a Recipient, as the "Evaluation Material") in
accordance with the provisions of this agreement, and to take or abstain from
taking certain other actions as hereinafter set forth. As used in this
agreement, a "Recipient's Representatives" shall include the directors,
officers, employees, agents, partners or advisors of such Recipient (including,
without limitation, attorneys, accountants, consultants, bankers and financial
advisors).

     The term "Evaluation Material" also shall be deemed to include all notes,
analyses, compilations, studies, interpretations or other documents prepared by
either Recipient or such Recipient's Representatives which contain, reflect or
are based upon, in whole or in part, the information furnished to such Recipient
or such Recipient's Representatives pursuant hereto. The term Evaluation
Material does not include information which (i) is or becomes generally
available to the public other than as a result of a disclosure by the Recipient
or such Recipient's Representatives in breach of this Agreement, (ii) was within
the Recipient's or such Recipient's Representatives' possession prior to its
being furnished to the Recipient or such Recipient's Representatives by or on
behalf of the Provider pursuant hereto, provided that the source of such
information was not known by the Recipient to be bound by a confidentiality
agreement with, or other contractual, legal or fiduciary obligation of
confidentiality to, the Provider or any other party with respect to such
information or (iii) becomes available to the Recipient or such Recipient's
Representatives on a non-confidential basis from a source other than the
Provider or any of its directors, officers, employees, agents or advisors
(including, without limitation, attorneys, accountants, consultants, bankers and
financial advisors) (collectively, "Provider Representatives"), provided that
such source is not known by the Recipient to be bound by a confidentiality
agreement with, or other contractual, legal or fiduciary obligation of
confidentiality to, the Provider or any other party with respect to such
information.

     Each Recipient hereby agrees that such Recipient and such Recipient's 
Representatives shall use the Evaluation Material solely for the purpose of 
evaluating a possible



 
<PAGE>
 
transaction between the Companies and for no other purpose, that the Evaluation
Material will be kept confidential and that the Recipient and such Recipient's 
Representatives will not disclose any of the Evaluation Material in any manner 
whatsoever: provided, however, that (i) the Recipient may make any disclosure of
such information as to which the Provider gives its prior written consent, and 
(ii) any of such information may be disclosed to the Recipient's Representatives
who need to know such information for the sole purpose of evaluating a possible 
transaction between the Companies, who are provided with a copy of this 
agreement and who you shall cause to be bound by the terms hereof to the same 
extent as if they were such Recipient. In any event, each Recipient agrees to 
undertake reasonable precautions to safeguard and protect the confidentiality of
the Evaluation Material, to accept responsibility for any breach of this 
agreement by any of such Recipient's Representatives, and at such Recipient's 
sole expense to take all reasonable measures (including but not limited to 
court proceedings) to restrain such Recipient's Representatives from prohibited 
or unauthorized disclosure or uses of the Evaluation Material.

          In addition, each Recipient agrees that, without the prior written 
consent of the Provider, such Recipient and such Recipient's Representatives 
will not disclose to any other person the fact that the Evaluation Material has 
been made available to such Recipient, that discussions or negotiations are 
taking place concerning a possible transaction between the Companies or any of 
the terms, conditions or other facts with respect thereto (including the status 
thereof); provided, however, that such Recipient may make such disclosure in 
the circumstances set forth in clause (i) or clause (ii) of the immediately 
preceding paragraph.

          In the event that either Recipient or any of such Recipient's 
Representatives are requested or required (by oral questions, interrogatories, 
requests for information or documents in legal proceedings, subpoena, civil 
investigative demand or other similar process) to disclose any of the Evaluation
Material, such Recipient shall provide the Provider with prompt written notice 
of any such request or requirement so that the Provider may seek a protective 
order or other appropriate remedy and/or waive compliance with the provision of
this agreement. If, in the absence of a protective order or other remedy or the 
receipt of a waiver by the Provider, the Recipient or any of such Recipient's 
Representatives are nonetheless, as advised by counsel, legally compelled to 
disclose Evaluation Material to any tribunal or else stand liable for contempt 
or suffer other censure or penalty, such Recipient or such Recipient's 
Representatives may, without liability hereunder, disclose to such tribunal only
that portion of the Evaluation Material which such counsel advises the Recipient
is legally required to be disclosed, provided that the Recipient exercises its 
best efforts to preserve the confidentiality of the Evaluation Material, 
including, without limitation, by cooperating with the Provider to obtain an 
appropriate protective order or other reliable assurance that confidential 
treatment will be accorded the Evaluation Material by such tribunal.

          If either Company decides that it does not wish to proceed with a 
transaction with the other, it will promptly inform the other of that decision. 
In that case, each Company will promptly deliver to the other Company all 
Evaluation Material (and all copies thereof) furnished to such Company in its 
capacity as a Recipient or such Recipient's Representatives by or on 

                                      -2-
<PAGE>
 
behalf of the other Company in its capacity as Provider pursuant hereto. In the 
event of such a decision, all other Evaluation Material prepared by either 
Company in its capacity as a Recipient or such Recipient's Representatives 
shall, at the Recipient's option, be destroyed or returned and no copy thereof 
shall be retained and the Recipient shall provide to the other Company a 
certificate of compliance with this sentence. Notwithstanding the return or 
destruction of the Evaluation Material, each Company in its capacity as a 
Recipient and such Recipient's Representatives will continue to be bound by 
such Recipient's respective obligations of confidentiality and other obligations
hereunder.

          Each Company understands and acknowledges that neither Company, in its
capacity as a Provider, nor such Provider's Representatives, makes any 
representation or warranty, express or implied, as to the accuracy or 
completeness of the Evaluation Material furnished by or on behalf of such 
Provider and shall have no liability to the other Company in its capacity as a 
Recipient or to any of such Recipient's Representatives relating to or resulting
from the use of the Evaluation Material furnished to such Recipient or any 
errors therein or omissions therefrom. Only those representations or warranties 
which are made in a final definitive agreement regarding any transactions 
contemplated hereby, when, as and if executed, and subject to such limitations 
and restrictions as may be specified therin, will have any legal effect.

          To the extent that any Evaluation Material may include materials 
subject to the attorney-client privilege, work product doctrine or any other 
applicable privilege concerning pending or threatened legal proceedings or 
governmental investigations, each Company understands and agrees that the 
Companies have a commonality of interest with respect to such matters and it is 
the desire, intention and mutual understanding of both Companies that the 
sharing of such material is not intended to, and shall not, waive or diminish in
any way the confidentiality of such material or its continued protection under 
the attorney-client privilege, work product doctrine or other applicable 
privilege. All Evaluation Material provided by either Company that is entitled 
to protection under the attorney-client privilege, work product doctrine or
other applicable privilege shall remain entitled to such protection under these
privileges, this agreement, and under the joint defense doctrine.

          Each Company, in its capacity as a Recipient, acknowledges and agrees 
that such Recipient is aware (and that such Recipient's Representatives are 
aware or, upon receipt of any Evaluation Material, will be advised by such 
Recipient) of the restrictions imposed by the United States federal securities 
laws and other applicable foreign and domestic laws on a person possessing 
material non-public information about a public company and that such Recipient 
and such Recipient's Representatives will comply with such laws.

          Each Company understands and agrees that no contract or agreement 
providing for any transaction between the Companies shall be deemed to exist 
between the Companies unless and until a final definitive agreement has been 
executed and delivered, and each Company hereby waives, in advance, any claims 
(including, without limitation, breach of contract) in connection with any such 
transaction unless and until both Companies shall have entered into a 

                                      -3-
<PAGE>
 
final definitive agreement. Each Company also agrees that unless and until a
final definitive agreement regarding a transaction between the Companies has
been executed and delivered, neither Company will be under any legal obligation
of any kind whatsoever with respect to such a transaction by virtue of this
agreement except for the matters specifically agreed to herein. Each Company
further acknowledges and agrees that the other Company reserves the right, in
its sole discretion, to reject any and all proposals made by the agreeing
Company or any of the persons who are Recipient Representatives or Provider
Representatives with respect to the agreeing Company with regard to a
transaction between the Companies, and, subject to the next paragraph of this
agreement, to terminate discussions and negotiations with the agreeing Company
at any time. Neither this paragraph nor any other provision in this agreement
can be waived or amended in favor of either Company except by written consent of
the other Company, which consent shall specifically refer to this paragraph (or
such provision) and explicitly make such waiver or amendment.

     [LeaRonal, Inc.] agrees that during the period commencing on the date
hereof and ending on the earlier of February 28, 1999 and three days after the
date on which [LeaRonal, Inc.] notifies [Rohm and Haas Company] in writing of
its intention to terminate discussions in regard to the transactions described
in the first paragraph of this agreement, neither [LeaRonal, Inc.] nor any of
its Provider or Recipient Representatives shall take any action to directly or
indirectly, encourage, initiate, solicit or engage in discussions or
negotiations with, or provide any information to, any entity or person other
that [Rohm and Haas Company] (and its Provider and Recipient Representatives)
concerning any Alternate Transaction (as defined below). For purposes hereof,
and "Alternate Transaction" shall mean (a) any stock purchase, merger,
consolidation, reorganization, change in organizational form, spin-off, split-
off, recapitalization, sale of equity interests or other similar transaction
involving [LeaRonal, Inc.] or any of its majority-owned affiliates which would
prejudice the ability of [Rohm and Haas Company] and [LeaRonal, Inc.] to
complete the transactions described in the first paragraph of this agreement, or
(b) any sale of all or any significant portion of [LeaRonal, Inc.'s] or any of
its majority-owner affiliates' business, operations or assets, or (c) any other
transaction or series of transactions which has substantially similar economic
effects.

     Each Company represents to the other Company that neither it nor its 
majority-owned affiliates beneficially own more than 1% of any class of 
securities entitled to be voted generally in the election of directors of the 
other Company (including for this purpose any direct or indirect options or 
other rights to acquire any such securities) ("Voting Securities").  Each 
Company agrees that, for a period of two years from the date of this agreement, 
except pursuant to the terms of a specific written request from the other 
Company that has been approved by its board of directors, neither such Company 
nor any of it majority-owned affiliates will (or will assist or encourage others
to):
     (1)  propose or publicly announce or otherwise disclose an intent to
          propose, or enter into or agree to enter into, singly or with any
          other person or directly or indirectly, any form of business
          combination, acquisition, restructuring,

                                      -4-
<PAGE>
 
     recapitalization or other transaction relating to the other Company or any 
     majority-owned affiliate thereof,

(2)  acquire, or offer, propose, seek or agree to acquire, by purchasing or
     otherwise, ownership (including as a beneficial owner) of any Voting
     Securities or any other securities, assets or businesses of the other
     Company or any of its majority-owned affiliates or any of their respective
     successors, or any options or other rights to acquire any such ownership
     from a third party or otherwise,

(3)  make, or in any way participate in, any solicitation of proxies with
     respect to any Voting Securities (including by the execution of action by a
     written consent) or take any similar action with respect to any Voting
     Securities, become a participant in any election contest with respect to
     the other Company, or seek to advise or influence any person with respect
     to any Voting Securities or demand a copy of the other Company's list of
     stockholders,

(4)  participate in or encourage the formation of any group that owns or seeks
     or offers to acquire beneficial ownership of any Voting Securities or seeks
     to affect control of the other Company or for the purpose of circumventing
     any provision of this agreement,

(5)  otherwise act, alone or in concert with others (including by providing
     financing for another person), to seek, offer or purpose to control or
     influence, in any manner, the board of directors, management or policies of
     the other Company,

(6)  publicly make or announce, or otherwise disclose an intent to propose, any
     demand, request or proposal to amend, waive or terminate any provision of
     this agreement,

(7)  enter into any discussions, negotiations, arrangements or understandings
     with any third party to facilitate or encourage the efforts of such third
     party with respect to any of the foregoing,

(8)  disclose any intention, plan or arrangement inconsistent with the 
     foregoing,

     or

(9)  take any action that would require the other Company to make a public 
     announcement regarding a possible transaction involving the other Company.

                                      -5-
<PAGE>
 
provided that (i) it is understood that the provisions of this paragraph shall 
not prohibit the ongoing discussion between the management of the respective 
Companies in respect of the transaction described in the first paragraph of this
agreement in accordance with the other provisions of this Agreement, and (ii) if
a Company enters into a definitive agreement with a third party pursuant to 
which such third party will make a tender or exchange offer for, or otherwise 
acquire (by merger, consolidation, purchase or otherwise), 50% or more of the 
common stock or other equity interests, assets or earning power of such other 
Company: then the other Company shall be permitted to contact privately the 
chairman of the board of directors of such Company (or any person designated by 
such chairman) and submit to such chairman or other person an offer to acquire
Voting Securities or assets of such Company and/or a request to negotiate with 
such Company with respect to such offer.

          Each Company agrees that, for a period of eighteen months from the
date of this agreement, it will not, directly or indirectly, solicit for 
employment or hire any employee of the other Company or any of the other 
Company's majority-owned affiliates with whom it has had contact or who was 
specifically identified to such Company during the period of its investigation 
of the other Company in connection with its consideration of a transaction 
between the Companies so long as such employee is employed by such other 
company; provided that the foregoing provision will not prevent either Company 
from employing any such person who contacts such Company on his or her own 
initiative without any direct or indirect solicitation by or encouragement from 
such Company; and provided further that such solicitation or hiring shall not be
deemed a breach of this agreement if (i) the personnel who performed such 
solicitation have no knowledge of any Evaluation Material provided by such other
Company, and (ii) none of the soliciting or hiring Company's personnel who have 
knowledge of any such Evaluation Material have actual advance knowledge of such
solicitation. For purposes of this paragraph, "solicit to employ" shall not be 
deemed to include any general solicitations of employment not specifically 
directed towards employees of the other Company.

          It is understood and agreed that no failure or delay by either Company
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 
future exercise thereof or the exercise of any other right, power or privilege 
hereunder.

          It is further understood and agreed that money damages would not be 
sufficient remedy for any breach of this agreement by either Company or any of 
its Recipient or Provider Representatives, as the case may be, and that the 
Company against which such breach is committed shall be entitled to equitable 
relief, including injunction and specific performance, as a remedy for any such 
breach. Such remedies shall not be deemed to be the exclusive remedies for a 
breach by either Company of this agreement but shall be in addition to all 
other remedies available at law or equity to the Company against which such 
breach is committed. In the event of litigation relating to this agreement, if a
court of competent jurisdiction determines that either 

                                      -6-
<PAGE>
 
Company or any of the persons who are Recipient Representatives or Provider
Representatives with respect to such Company has breached this agreement, then
the Company which, or the Recipient Representatives or Provider Representatives
of which, is determined to have so breached shall be liable and pay to the other
Company the reasonable legal fees incurred by the other Company in connection
with such litigation, including any appeal therefrom.

          This agreement is for the benefit of each Company, the persons who are
Recipient Representatives or Provider Representatives with respect to such 
Company and their respective directors, officers, stockholders, owners, 
affiliates, and agents, and shall be governed by and construed in accordance 
with the laws of the State of New York applicable to agreements made and to be 
performed entirely within such State.

          This agreement shall terminate immediately upon written notice given
by either Company to the other, provided that in any event the confidentiality
(and related enforcement) provisions in this agreement shall survive until
the fifth anniversary of the date hereof.

          This agreement contains the entire agreement between the Companies
regarding the subject matter hereof and supersedes all prior agreements,
understandings, arrangements and discussions between the Companies regarding
such subject matter.

          This agreement may be signed in counterparts, each of which shall be 
deemed an original but all of which shall be deemed to constitute a single 
instrument.

          IN WITNESS WHEREOF, each Company has caused this agreement to be 
signed by its duly authorized representatives as of the date written below.

                          TENDER AND OPTION AGREEMENT
                          ---------------------------

                                        

          TENDER AND OPTION AGREEMENT, dated as of December 20, 1998 (the
"Agreement"), among Rohm and Haas Company, a Delaware corporation ("Parent"),
Lightning Acquisition Corp., a New York corporation and a wholly owned
subsidiary of Parent ("Purchaser"), LeaRonal, Inc., a New York corporation (the
"Company") and each of the persons listed on Schedule A hereto (each a
"Stockholder" and, collectively, the "Stockholders").

          WHEREAS, Parent, Purchaser and the Company propose to enter into an
Agreement and Plan of Merger dated as of the date hereof (as the same may be
amended or supplemented, the "Merger Agreement") providing for, among other
things, the making of a cash tender offer (as such offer may be amended from
time to time as permitted under the Merger Agreement, the "Offer") by Purchaser
for all of the issued and outstanding shares of common stock, par value $1.00
per share, of the Company (referred to herein as either the "Shares" or "Company
Common Stock") and the merger of the Company and Purchaser on the terms and
conditions set forth in the Merger Agreement (the "Merger");

          WHEREAS, each Stockholder is the beneficial owner of the Shares set
forth opposite such Stockholder's name on Schedule A hereto; such Shares, as
such Shares may be adjusted by stock dividend, stock split, recapitalization,
combination or exchange of shares, merger, consolidation, reorganization or
other change or transaction of or by the Company, together with Shares issuable
upon the exercise of options (including the Options set forth in Schedule A) (as
the same may be adjusted as aforesaid), being collectively referred to herein as
the "Shares" of such Stockholder; and

          WHEREAS, as a condition to their willingness to enter into the Merger
Agreement, Parent and Purchaser have requested that the Stockholders enter into
this Agreement;

          NOW, THEREFORE, to induce Parent and Purchaser to enter into, and in
consideration of their entering into, the Merger Agreement, and in consideration
of the premises and the representations, warranties and agreements contained
herein, the parties agree as follows:

        Section 1.  Certain Definitions.  Capitalized terms used but not 
                    -------------------
otherwise defined herein have the meanings ascribed to such terms in the Merger
Agreement.

        Section 2.  Representations and Warranties of the Stockholders.  Each
                    --------------------------------------------------       
Stockholder, severally and not jointly, represents and warrants to Parent and
Purchaser, as of the date hereof and as of the Closing (as defined below), as
follows:

                (a)  The Stockholder is the beneficial owner (as defined in Rule
13d-3 under the Securities Exchange Act of 1934, as amended (the "Exchange
Act"), which meaning will apply for all purposes of this Agreement) of, and has
good title to, all of the Shares (including the Options), free and clear of any
mortgage, pledge, hypothecation, rights of others, claim, security
<PAGE>
 
interest, charge, encumbrance, title defect, title retention agreement, voting
trust agreement, interest, option, lien, charge or similar restriction or
limitation, including any restriction on the right to vote, sell or otherwise
dispose of the Shares (each, a "Lien"), except as set forth in this Agreement.

                (b)  The Shares (including the Options) constitute all of the
securities (as defined in Section 3(a)(10) of the Exchange Act, which definition
will apply for all purposes of this Agreement) of the Company beneficially
owned, directly or indirectly, by the Stockholder.

                (c)  Except for the Shares (including the Options), the
Stockholder does not, directly or indirectly, beneficially own or have any
option, warrant or other right to acquire any securities of the Company that are
or may by their terms become entitled to vote or any securities that are
convertible or exchangeable into or exercisable for any securities of the
Company that are or may by their terms become entitled to vote, nor is the
Stockholder subject to any Contract, commitment, arrangement, understanding,
restriction or relationship (whether or not legally enforceable), other than
this Agreement, that provides for such Stockholder to vote or acquire any
securities of the Company. The Stockholder holds exclusive power to vote the
Shares and has not granted a proxy to any other person (as defined in the Merger
Agreement, which meaning will apply for all purposes of this Agreement) to vote
the Shares, subject to the limitations set forth in this Agreement.

                (d)  This Agreement has been duly executed and delivered by the
Stockholder and, assuming due authorization, execution and delivery of this
Agreement by Parent and Purchaser, is a valid and binding obligation of the
Stockholder enforceable against the Stockholder in accordance with its terms.

                (e)  Neither the execution and delivery of this Agreement nor
the performance by the Stockholder of the Stockholder's obligations hereunder
will conflict with, result in a violation or breach of, or constitute a default
(or an event that, with notice or lapse of time or both, would result in a
default) or give rise to any right of termination, amendment, cancellation, or
acceleration or result in the creation of any Lien on any Shares under, (i) any
Contract, commitment, agreement, understanding, arrangement or restriction of
any kind to which the Stockholder is a party or by which the Stockholder is
bound or (ii) any injunction, judgment, writ, decree, order or ruling applicable
to the Stockholder; except for conflicts, violations, breaches, defaults,
terminations, amendments, cancellations, accelerations or Liens that would not
individually or in the aggregate be reasonably expected to prevent or materially
impair or delay the consummation by such Stockholder of the transactions
contemplated hereby.

                (f)  Neither the execution and delivery of this Agreement nor
the performance by the Stockholder of the Stockholder's obligations hereunder
will violate any law, decree, statute, rule or regulation applicable to the
Stockholder or require any order, consent, authorization or approval of, filing
or registration with, or declaration or notice to, any court, administrative
agency or other governmental body or authority, other than any required notices
or filings pursuant to the Hart-Scott-Rodino Antitrust Improvements Act of 1976,
as amended, and the rules and regulations promulgated thereunder (the "HSR
Act"), foreign antitrust or competition laws or the federal securities laws.

                (g)  The Stockholder understands and acknowledges that Parent is
entering into, and causing Purchaser to enter into, the Merger Agreement in
reliance upon the Stockholder's execution and delivery of this Agreement.

        Section 3.  Representations and Warranties of the Company.  The Company
                    ---------------------------------------------

laws.

                (e)  Any Shares acquired upon exercise of the Purchase Option
(as defined below) will be acquired for Parent's or Purchaser's own account, for
investment purposes only and will not be, and the Purchase Option is not being,
acquired by Parent and Purchaser with a view to public distribution thereof in
violation of any applicable provisions of the Securities Act of 1933, as amended
(the "Securities Act").

        Section 5.  Transfer of the Shares.  During the term of this Agreement,
                    ----------------------
except as otherwise expressly provided herein, each Stockholder agrees that such
Stockholder will not (a) tender into any tender or exchange offer or otherwise

with any Lien, any of the Shares, except for (i) transfers to any spouse or

shares of Company Common Stock or other securities of the Company (otherwise
than in connection with a transaction of the type described in Section 6 or by
exercising any of the 

                                      -4-

action that would in any way restrict, limit or interfere with the performance

hereby or which would otherwise diminish the benefits of this Agreement to
Parent or Purchaser.

        Section 6.  Adjustments.
                    -----------

                (a)  In the event (i) of any stock dividend, stock split,
recapitalization, reclassification, combination or exchange of shares of capital
stock or other securities of the Company on, of or affecting the Shares or the
like or any other action that would have the effect of changing a Stockholder's
ownership of the Company's capital stock or other securities or (ii) a
Stockholder becomes the beneficial owner of any additional Shares of or other
securities of the Company, then the terms of this Agreement will apply to the
shares of capital stock held by such Stockholder immediately following the
effectiveness of the events described in clause (i) or such Stockholder becoming
the beneficial owner thereof, as described in clause (ii), as though they were
Shares hereunder.

                (b)  Each Stockholder hereby agrees, while this Agreement is in
effect, to promptly notify Parent and Purchaser of the number of any new Shares
acquired by such Stockholder, if any, after the date hereof.

        Section 7.  Tender of Shares.  Each Stockholder hereby agrees that such
                    ----------------                                           
Stockholder will validly tender (or cause the record owner of such shares to
validly tender) and sell (and not withdraw, except in the event the Purchase
Option is exercised, in which case such withdrawal shall be for the limited
purpose of consummating the Purchase Option) pursuant to and in accordance with
the terms of the Offer not later than the fifth business day after commencement
of the Offer (or the earlier of the expiration date of the Offer and the fifth
business day after such Shares are acquired by such Stockholder if the
Stockholder acquires Shares after the date hereof), or, if the Stockholder has
not received the Offer Documents by such time, within two business days
following receipt of such documents, all of the then outstanding shares of
Company Common Stock beneficially owned by such Stockholder (including the
shares of Company Common Stock outstanding as of the date hereof and set forth
on Schedule A hereto opposite such Stockholder's name).  Upon the purchase by
Purchaser of all of such then outstanding shares of Company Common Stock
beneficially owned by such Stockholder pursuant to the Offer in accordance with
this Section 7, this Agreement will terminate as it relates to such Stockholder.
In the event, notwithstanding the provisions of the first sentence of this
Section 7, any Shares beneficially owned by a Stockholder are for any reason
withdrawn from the Offer or are not purchased pursuant to the Offer, such Shares
will remain subject to the terms of this Agreement.  Each Stockholder
acknowledges that Purchaser's obligation to accept for payment and pay for the
shares of Company Common Stock tendered in the Offer is subject to all the terms
and conditions of the Offer.

        Section 8.  Voting Agreement.  Each Stockholder, by this Agreement, 
                    ----------------
does hereby (a) agree to appear (or not appear, if requested by Parent or
Purchaser) at any annual, special, postponed or adjourned meeting of the
stockholders of the Company or otherwise cause the Shares such Stockholder
beneficially owns to be counted as present (or absent, if requested by Parent or
Purchaser) thereat for purposes of establishing a quorum and to vote or consent,
and (b) constitute and appoint Parent and Purchaser, or any nominee thereof,
with full power of substitution, during and for the term of this Agreement, as
his true and lawful attorney and proxy for and in his name, place and stead, to
vote all the Shares such Stockholder beneficially owns at the time of such vote,
at any annual, special, postponed or adjourned meeting of the stockholders of
the Company (and this appointment will include the right to sign his or its name
(as stockholder) to any consent, certificate or other document relating to the
Company that laws of the State of New York may require or permit), in the case
of both (a) and (b) above, (x) in favor of approval and adoption of the Merger
Agreement and approval and adoption of the Merger and the other transactions
contemplated thereby and (y) against (1) any Acquisition Proposal, (2) any
action or agreement that would result in a breach in any respect of any
covenant, agreement, representation or warranty of the Company under the Merger
Agreement and (3) the following actions (other than the Merger and the other
transactions contemplated by the Merger Agreement): (i) any extraordinary
corporate transaction, such as a merger, consolidation or other business
combination involving the Company or any of its subsidiaries; (ii) a sale, lease
or transfer of a material amount of assets of the Company or any of its
subsidiaries, or a reorganization, recapitalization, dissolution or liquidation
of the Company or any of its subsidiaries; (iii) (A) any change in a majority of
the persons who constitute the board of directors of the Company or any of its
subsidiaries as of the date hereof; (B) any change in the present capitalization
of the Company or any amendment of the Company's or any of its subsidiaries'
certificate of incorporation or bylaws, as amended to date; (C) any other
material change in the Company's or any of its subsidiaries' corporate structure
or business; or (D) any other action that is intended, or could reasonably be
expected, to impede, interfere with, delay, postpone, or adversely affect the
Offer, the Merger and the other transactions contemplated by this Agreement and
the Merger Agreement. This proxy and power of attorney is a proxy and power
coupled with an interest, and each Stockholder declares that it is irrevocable
until this Agreement shall terminate in accordance with its terms. Each
Stockholder hereby revokes all and any other proxies with respect to the Shares
that such Stockholder may have heretofore made or granted. For Shares as to
which a Stockholder is the beneficial but not the record owner, such Stockholder
shall use his or its best efforts to cause any record owner of such Shares to
grant to Parent a proxy to the same effect as that contained herein. Each
Stockholder hereby agrees to permit Parent and Purchaser to publish and disclose
in the Offer Documents and the Proxy Statement and related filings under the
securities laws such Stockholder's identity and ownership of Shares and the
nature of his or its commitments, arrangements and understandings under this
Agreement. Notwithstanding the foregoing, Alonna Ostad, Sharone N. Ostrow and
Jonathan Ostrow are not bound by the terms of this Section 8.

        Section 9.  No Solicitation.  Each Shareholder agrees that neither such
                    ---------------
Stockholder nor any of such Stockholder's officers, directors, employees,
trustees, representatives, agents or affiliates (including, without limitation,
any investment banker, attorney or accountant retained by any of them) will
directly or indirectly initiate, solicit or encourage (including by way of
furnishing

                                      -6-
<PAGE>
 
non-public information or assistance), or take any other action to facilitate,
any inquiries or the making or submission of any Acquisition Proposal, or enter
into or maintain or continue discussions or negotiate with any person or entity
in furtherance of such inquiries or to obtain or induce any person to make or
submit an Acquisition Proposal or agree to or endorse any Acquisition Proposal
or assist or participate in, facilitate or encourage, any effort or attempt by
any other person or entity to do or seek any of the foregoing or authorize or
permit any of its officers, directors, employees, trustees or any of its
affiliates or any investment banker, financial advisor, attorney, accountant or
other representative or agent retained by any of them to take any such action.
Each Stockholder shall immediately advise Parent in writing of the receipt of
request for information or any inquiries or proposals relating to an Acquisition
Proposal.

        Section 10.  Grant of Purchase Option.  The Stockholder hereby grants 
                     ------------------------
to Parent and Purchaser an irrevocable option (the "Purchase Option") to
purchase for cash, in a manner set forth below, any or all of the Shares (and
including Shares acquired after the date hereof by such Stockholder)
beneficially owned by the Stockholder at a price (the "Exercise Price") per
Share equal to $34.00 (the "Offer Price"). In the event of any stock dividends,
stock splits, recapitalizations, combinations, exchanges of shares or the like,
the Offer Price will be appropriately adjusted for the purpose of this Section
10.

        Section 11.  Exercise of Purchase Option.
                     --------------------------- 

                (a)  Subject to the conditions set forth in Section 13 hereof,
the Purchase Option may be exercised by Parent or Purchaser, in whole or in
part, at any time or from time to time after the occurrence of any Trigger Event
(as defined below). The Company and each Stockholder shall notify Parent
promptly in writing of the occurrence of any Trigger Event, it being understood
that the giving of such notice by the Company or the Stockholder is not a
condition to the right of Parent or Purchaser to exercise the Purchase Option.
In the event Parent or Purchaser wishes to exercise the Purchase Option, Parent
shall deliver to each Stockholder a written notice (an "Exercise Notice")
specifying the total number of Shares it wishes to purchase from such
Stockholder. Each closing of a purchase of Shares (a "Closing") will occur at a
place, on a date and at a time designated by Parent or Purchaser in an Exercise
Notice delivered at least two business days prior to the date of the Closing.

                (b)  A "Trigger Event" means any one of the following: (i) the
Merger Agreement becomes terminable under circumstances that entitle Parent or
Purchaser to receive the Termination Fee or the Expenses under Section 8.3(b) of
the Merger Agreement (regardless of whether the Merger Agreement is actually
terminated and whether such Termination Fee or Expenses are then actually paid),
(ii) the Offer is consummated but, due to the failure of the Stockholder to
validly tender and not withdraw all of the then outstanding shares of Company
Common Stock beneficially owned by such Stockholder, the Purchaser has not
accepted for payment or paid for all of such shares of Company Common Stock,
(iii) a tender or exchange offer for at least 20% of the shares of Company
Common Stock shall have been publicly proposed to be made or shall have been
made by another person, or (iv) it shall have been publicly disclosed or Parent
or Purchaser shall have otherwise learned that (A) any person or "group" (as
defined in Section 13(d)(3) of the Exchange Act) (other than Parent or
Purchaser) shall have acquired or proposed to acquire beneficial ownership of
more than 20% of any class or series of capital stock 

                                      -7-
<PAGE>
 
of the Company (including the Company Common Stock), through the acquisition of
stock, the formation of a group or otherwise, or shall have been granted any
option, right or warrant, conditional or otherwise, to acquire beneficial
ownership of more than 20% of any class or series of capital stock of the
Company or any of its subsidiaries, or (B) any person or group (other than
Parent and Purchaser) shall have entered into or publicly offered to enter into
a definitive agreement or an agreement in principle with respect to a merger,
consolidation or other business combination with the Company or any of its
subsidiaries.

                (c)  If requested by Parent and Purchaser in the Exercise
Notice, such Stockholder shall exercise all Options (to the extent exercisable)
and other rights (including conversion or exchange rights) beneficially owned by
such Stockholder and shall sell or, if directed by Parent and Purchaser, tender
the Shares acquired pursuant to such exercise to Parent or Purchaser as provided
in this Agreement.

                (d)  In the event (i) Parent or Purchaser exercises the Purchase
Option and purchases Shares pursuant to this Section 11 representing at least
20% of the then outstanding shares of Company Common Stock on a fully diluted
basis (the "Purchase Event"), (ii) no Acquisition Proposal shall have been
consummated and (iii) the Merger Agreement shall have terminated and the Company
shall not have been in material breach of the Merger Agreement at the time of
such termination, upon the written request of the Company made within five
business days after the Purchase Event, Parent shall cause Purchaser or another
subsidiary of Parent to commence, as soon as reasonably practicable, a tender
offer for all shares of Company Common Stock at a cash price equal to the Offer
Price, on terms and subject to conditions substantially similar to those
contained in the Merger Agreement.

                (e)  If, within twelve months following the exercise of the
Purchase Option by Parent or Purchaser, Parent or Purchaser sells any or all of
the Shares acquired upon exercise of the Purchase Option to an unaffiliated
third party (a "Subsequent Sale") at a per Share price in excess of the Offer
Price (the "Subsequent Sale Price"), then Parent or Purchaser will pay to each
Stockholder, within five days of receipt of payment by Parent or Purchaser, an
amount equal to such Stockholder's pro rata share of 50% of the excess of the
Subsequent Sale Price over the Offer Price multiplied by the number of shares
sold in the Subsequent Sale.

        Section 12.  Termination of Purchase Option.  The Purchase Option will
                     ------------------------------
terminate (a) if this Agreement terminates pursuant to Section 7 or (b) upon the
earliest of: (i) the Effective Time; (ii) termination of the Merger Agreement
other than upon, during the continuance of or after a Trigger Event; or (iii) 90
days following any termination of the Merger Agreement upon, during the
continuance of or after a Trigger Event (or if, at the expiration of such 90 day
period the Purchase Option cannot be exercised by reason of any applicable
judgment, decree, order, injunction, law or regulation, 10 business days after
such impediment to exercise has been removed or has become final and not subject
to appeal). Upon the giving by Parent or Purchaser to the Stockholder of the
Exercise Notice and the tender of the aggregate Exercise Price, Parent or
Purchaser, as the case may be, will be deemed to be the holder of record of the
Shares transferable upon such exercise, notwithstanding that the stock transfer
books of the Company are then closed or that certificates representing such
Shares have not been actually delivered to Parent.

        Section 13.  Conditions To Closing.  The obligation of each 
                     ---------------------
Stockholder to sell such Stockholder's Shares to Parent or Purchaser hereunder
is subject to the conditions that (i) all waiting periods, if any, under the HSR
Act, applicable to the sale of the Shares or the acquisition of the Shares by
Parent or Purchaser, as the case may be, hereunder have expired or have been
terminated; (ii) all consents, approvals, orders or authorizations of, or
registrations, declarations or filings with, any court, administrative agency or
other Governmental Entity, if any, required in connection with sale of the
Shares or the acquisition of the Shares by Parent or Purchaser hereunder have
been obtained or made; and (iii) no preliminary or permanent injunction or other
order by any court of competent jurisdiction prohibiting or otherwise
restraining such sale or acquisition is in effect.

        Section 14.  Closing.  At any Closing with respect to Shares 
                     -------
beneficially owned by a Stockholder, (a) such Stockholder will deliver to
Parent, Purchaser or their respective designee a certificate or certificates in
definitive form representing the number of the Shares designated by Parent or
Purchaser, as the case may be, in its Exercise Notice, such certificate to be
registered in the name of Parent, Purchaser or their respective designee and (b)
Parent or Purchaser, as the case may be, will deliver to the Stockholder the
aggregate Exercise Price for the Shares so designated and being purchased by
wire transfer of immediately available funds.

        Section 15.  Registration Rights.
                     ------------------- 

                (a)  Following termination of the Merger Agreement, Parent or
Purchaser may in its sole discretion (but shall not be required) by written
notice (the "Registration Notice") to the Company request the Company to
register under the Securities Act all or any part of the shares of Company
Common Stock acquired under the Purchase Option (the "Registrable Securities").

                (b)  The Company shall use commercially reasonable efforts to
effect, as promptly as practicable, the registration under the Securities Act of
the Registrable Securities; provided, however, that (i) Parent and Purchaser
will be entitled to no more than one effective registration statement hereunder
and (ii) the Company will not be required to file any such registration
statement during any period of time (not to exceed 40 days after such request in
the case of clause (A) below or 90 days in the case of clauses (B) and (C)
below) when (A) the Company is in possession of material non-public information
that it reasonably believes would be detrimental to be disclosed at such time
and that such information would have to be disclosed if a registration statement
were filed at that time; (B) the Company is required under the Securities Act to
include audited financial statements for any period in such registration
statement and such financial statements are not yet available for inclusion in
such registration statement; or (C) the Company determines, in its reasonable
judgment, that such registration would interfere with any proposed financing,
acquisition or other material transaction involving the Company or any of its
affiliates. The Company shall use its reasonable best efforts to cause any
Registrable Securities registered pursuant to this Section 15 to be qualified
for sale under the securities or blue-sky laws of such jurisdictions as Parent
or Purchaser may reasonably request and shall continue such registration or
qualification in effect in such jurisdiction; provided, however, that the
Company will not be required to qualify to do business in, or to consent to
general service of process in, any jurisdiction by reason of this provision.

<PAGE>
 
                (c)  The registration rights set forth in this Section 15 are
subject to the condition that Parent and Purchaser shall provide the Company
with such information with respect to their Registrable Securities, the plans
for the distribution thereof, and such other information with respect to such
holder as, in the reasonable judgment of counsel for the Company, is necessary
to enable the Company to include in such registration statement all material
facts required to be disclosed with respect to a registration thereunder.

                (d)  A registration effected under this Section 15 will be
effected at the Company's expense, except for underwriting discounts and
commissions and the fees and the expenses of counsel to Parent and Purchaser
(which will be paid by Parent and Purchaser, and the Company shall provide to
the underwriters (in connection with an underwritten offering) such
documentation (including certificates, opinions of counsel and "comfort" letters
from auditors) as are customary in connection with underwritten offerings as
such underwriters may reasonably require. In connection with any such
registration, the parties agree (i) to indemnify each other and the underwriters
in the customary manner, (ii) to enter into an underwriting agreement in form
and substance customary for transactions of such type with the underwriters
participating in such offering and (iii) to take all further actions that will
be reasonably necessary to effect such registration and sale (including, if the
underwriters deem it necessary, participating in road-show presentations).

        Section 16.  Termination. This Agreement will terminate (a) as to any
                     -----------                                             
Stockholder upon the purchase of all the Shares beneficially owned by such
Stockholder pursuant to the Offer in accordance with Section 7, (b) except for
Sections 10, 11, 12, 13, 14 and 15 hereof, which will only terminate as and when
provided therein, on the earlier to occur of (i) the Effective Time or (ii) the
date the Merger Agreement is terminated in accordance with its terms, or (c) by
the mutual consent of each Stockholder as to its rights and obligations
hereunder, the Board of Directors of the Company and the Board of Directors of
Parent.

        Section 17.  Expenses.  Except as otherwise expressly provided herein

parties hereto will be borne by the party incurring such costs and expenses.

        Section 18.  Further Assurances.  Each party hereto will execute and 
                     ------------------
deliver all such further documents and instruments and take all such further
action as may be reasonably necessary in order to consummate the transactions
contemplated hereby. The Company covenants to Parent and Purchaser that it and
its Board of Directors shall (i) take all action necessary to ensure that no
state takeover statute or similar statute or regulation is or becomes applicable
to the Purchase Option, the Offer, the Merger, this Agreement, the Merger
Agreement or any of the other transactions contemplated by the foregoing (the
"Transactions") and (ii) if any state takeover statute or similar statute or
regulation becomes applicable to any of the Transactions, take all action
necessary to ensure that the Purchase Option and the other Transactions may be
consummated as promptly as practicable on the terms contemplated by this
Agreement and the Merger Agreement and otherwise to minimize the effect of such
statute or regulation on the Purchase Option and the other Transactions.

or the Merger Agreement or the other transactions contemplated hereby or thereby
without the consent of Parent and Purchaser, except as may be required by law or
applicable stock exchange rules.

        Section 20.  Stop Transfer Order; Legend.  The Company agrees with, and
                     ---------------------------                               
covenants to, Parent and Purchaser that the Company shall not register the
transfer of any certificate representing any Stockholder's Shares unless such
transfer is made in accordance with the terms of this Agreement.  Each
Stockholder agrees to place the following legend on any and all certificates
evidencing the Shares:

          THE SHARES OF COMMON STOCK REPRESENTED BY THIS CERTIFICATE ARE SUBJECT

provision of this Agreement will not operate as or be construed to be a waiver
of any other breach of such provision or of any breach of any other provision of
this Agreement. The failure of a party to insist upon strict adherence to any
term of this Agreement or one or more sections hereof will not be considered a
waiver or deprive that party of the right thereafter to insist upon strict

Agreement or otherwise available in respect hereof at law or in equity will be

                             EMPLOYMENT AGREEMENT
                             --------------------

          AGREEMENT made as of the 20th day of December, 1998, by and between
LEARONAL, INC., a New York corporation, having its office and place of business
at 272 Buffalo Avenue, Freeport, New York 11520 (the "Company") and [        ],
residing at [        ] (the "Executive").

                                  BACKGROUND
                                  ----------

          The Company has entered into an Agreement and Plan of Merger dated
December 20, 1998 among the Company, ROHM AND HAAS COMPANY ("Parent") and
LIGHTNING ACQUISITION CORP. ("Purchaser") (the "Merger Agreement").

          Parent, Purchaser and the Company want to continue the employment
relationship between Executive and the Company following the effective date of
the contemplated merger (the "Merger") and the Executive wants to continue in
that employment, in each case on the terms and conditions set forth herein.

                                   AGREEMENT
                                   ---------

          Accordingly, in consideration of the mutual promises contained herein,
and intending to be legally bound, the Company and the Executive agree that
contingent upon, and effective upon the date of the earlier of the consummation
of the Offer or the Merger (as such terms are defined in the Merger Agreement),
(a) all prior employment agreements and amendments thereto are hereby amended
and restated in their entirety as follows, and simultaneously with the earlier
to occur of the Offer or the 
<PAGE>
 
Merger, will be of no further effect, and (b) that the Executive will remain
employed by the Company on the terms and conditions set forth herein.

          1.   Employment; Duties:

               (A)  The Company hereby continues the employment of the Executive
and the Executive hereby accepts such continued employment on the terms and
conditions hereinafter set forth. During his employment hereunder, the Executive
shall serve as [       ] of the Company, and shall have and perform such duties
and responsibilities relating to the business and operations of the Company as
may be appropriate to such position, and as the Board of Directors from time to
time may assign to him, consistently with the requirement that his duties be
appropriate to his position, subject to reasonable vacation periods and other
leaves of absence.

               (B)  During his employment hereunder, the Executive shall devote
his full time, attention and best efforts to the business of the Company and to
the furtherance of its interests, and shall not, without the prior written
consent of the Board of Directors of the Company, directly or indirectly, engage

               (C)  The principal place of performance of the Executive's
services hereunder shall be Freeport, New York, subject to reasonable travel
requirements on behalf of the Company.

               (D)  The Executive represents and warrants that he is free to
enter into this Agreement and the performance of his obligations and duties in
the manner contemplated hereunder will not violate the provisions of any other
agreement or understanding to which he is a party or by which he is bound.

          2.   Term: The term of this Agreement shall be for the period
               ----                                                    
commencing on the earlier of the date of the consummation of the Offer or the
date of the Merger and ending on the third anniversary of that date.

          3.   Compensation:
               ------------ 

               (A)  As compensation for the Executive's services hereunder, the
Company shall pay and the Executive shall accept an annual salary ("Base
Salary") of not less than [       ] Dollars per year, or such greater sum as the
Company may from time to time deem appropriate, payable in such installments and
at such regular intervals as the Company may from time to time use for the
payment of salaries, but not less frequently than monthly.

               (B)  Executive shall also be entitled to participate in an annual
bonus program that shall provide an opportunity to receive an annual bonus,
including for the year, if any that begins before and ends after the Effective
Time, that is as a dollar amount at least consistent with the opportunity
provided to him in accordance with the Company's practices and policies in
effect before the Effective Time, based on

                                      -3-
<PAGE>
 
performance objectives established by the Board, in consultation with the Chief
Executive Officer, following the Effective Time.

               (C)  In addition to the compensation set forth in (A) above, to
induce the Executive to remain in the employ of the Company, and as additional
compensation for the critical services to rendered by the Employee during the
difficult period of integration and transition following the Effective Time, the
Executive shall be entitled on the first anniversary of the effective date of
this Agreement, to an amount equal to 60% of the annual Compensation then
payable under (A) above, provided that the Executive is employed on the payment
date. If the Executive's employment is terminated by the Company without Cause,
or by the Executive for Good Reason, the Executive shall be paid a pro rata
portion of the amount otherwise payable under this Section 3(C) determined by
dividing the number of days elapsed from the beginning of the term of this
Agreement (determined under Section 2) by 365. If the Executive's employment
hereunder is terminated for any other reason, no payment shall be made under
this Section 3(C).

          4.   Additional Benefits:
               ------------------- 

               (A)  The Company shall provide the Executive with such
retirement, medical and other fringe benefits as the Company or the Parent may
from time to time decide to generally provide for the Company's similarly
situated executive personnel, provided that during the term of this Agreement,
the total of such benefits shall be substantially comparable in the aggregate to
those provided to the Executive before the Effective Time. Until the third
anniversary of the Effective Time, as defined

                                      -4-
<PAGE>
 
in the Merger Agreement, there shall be no adverse change or reduction in the
level or amount of any Executive perquisite made available to the Executive
immediately before the Effective Time.

               (B)  The Company shall reimburse the Executive for all reasonable
and necessary travel, entertainment and other expenses incurred by the Executive
in connection with the performance of his duties hereunder, provided such
expenses are documented and vouchers supported by receipts are submitted; the
good faith determination of the Company as to the reasonableness and necessity
of any such expense shall be binding and conclusive. Any reimbursed expense
which is disallowed as the result of any audit of the Company's tax returns by
any governmental taxing authority shall be refunded by the Executive to the
Company promptly following such disallowance.

          5.   Stock Option Payments:  Executive agrees with respect to each
               ---------------------                                        
outstanding stock option (each "Option") heretofore granted under the Company's
1990 Nonqualified Stock Option Plan, dated June 1, 1990 (the "1990 Plan") and
the Company's 1996 Long-Term Incentive Plan (the "1996 Plan", and together with
the 1990 Plan, the "Company Stock Option Plans"), to be bound by the terms of
Section 2.10 of the Merger Agreement.

          6.   Termination:
               ----------- 

               (A)  The Company may terminate the Executive's employment at any
time for "Cause" or upon 90 days notice for any other reason. The Executive may

                                      -5-
<PAGE>
 
terminate employment hereunder upon 90 days written notice, with or without
"Good Reason."

               (B)  If the Executive's employment is terminated for "Cause" or
by the Executive without "Good Reason" the Executive shall have no further
rights under this Agreement, except the right to receive the Compensation
payable under Section 3 up to the date of termination by the Company of the
Executive's employment hereunder, and the right to receive any vested benefits
under any plan or arrangement described in Section 4. The Executive's employment
shall be deemed to have been terminated for "Cause" if his employment is
terminated for: (i) embezzlement, theft, or other misappropriation of any
property of more than nominal value of the Company; (ii) the Executive's neglect
of, or failure substantially to perform or comply with, his duties,
responsibilities and obligations as an officer of the Company (other than any
such failure resulting from his incapacity due to physical or mental illness, as
determined by a physician appointed by the Company) after a demand for
substantial performance is delivered to the Executive by the Board which
specifically identifies the manner in which such Board believes that the
Executive has not substantially performed his duties and the Executive fails or
refuses to remedy such failure to the reasonable satisfaction of the Board
within ninety (90) days after the receipt of such notice; (iii) the Executive's
willful and material breach of his restrictive covenants set forth in this
Agreement; (iv) any act which if the subject of a criminal proceeding could
reasonably result in a conviction for a felony; (v) an act or acts of dishonesty
on the Executive's part intended to result or resulting in substantial gain or
personal enrichment to him at

                                      -6-
<PAGE>
 
the expense of the Company or (vi) a material breach of the Parent's Code of
Business Conduct or other policies governing employee conduct.

               (C)  In the event the Executive's employment is terminated by the
Company without "Cause" or by the Executive with "Good Reason," the Executive
shall have the right to receive (a) the Compensation payable under Section 3 and
(b) continuation of the benefits in which the Executive is participating under
Section 4 on the date of termination, in each case for the remaining term of
this Agreement following the date of such termination without "Cause." The
amount payable under (a) above shall be paid in a lump sum within 30 days of the
date of the Executive's termination without "Cause."

               (D)  "Good Reason" shall mean, without the Executive's express
prior written consent, the occurrence of any one or more of the following:(i)
The assignment of the Executive to duties materially inconsistent with the
Executive's authorities, duties, responsibilities, and status (including titles
and reporting requirements) as an officer of the Company, or a material
reduction or alteration in the nature or status of the Executive's authorities,
duties, or responsibilities from those in effect as of the effective date (or as
subsequently increased), other than an insubstantial and inadvertent act that is
remedied by the Company promptly after receipt of notice thereof given by the
Executive; (ii) The Company's requiring the Executive to be based at a location
in excess of twenty five (25) miles from the location of the Executive's
principal job location or office as of the effective date, except for required
travel on the Company's business to an extent substantially consistent with the

                                      -7-
<PAGE>
 
Executive's present business obligations; (iii) A reduction by the Company of
the Executive's Base Salary as in effect on the effective date, or as the same
shall be increased from time to time; (iv)  A failure by the Company to provide
the benefits described in Section 4, other than an immaterial failure that is
remedied by the Company promptly after the receipt of timely notice thereof
given by the Executive.  For this purpose, the Company may eliminate and/or
modify existing programs and coverage levels; provided, however, that the
Executive's level of coverage under all such programs must be at least as great
as is such coverage provided to executives who have the same or lesser levels of
reporting responsibilities within the Company's organization;

               (E)  Any provision hereof to the contrary notwithstanding, if
this Agreement shall not have previously expired or the Executive's employment
hereunder shall not have otherwise been sooner terminated, the Executive's
employment hereunder shall automatically terminate upon:

          (i)  the Executive's becoming physically or mentally disabled so as to
               be unable to perform the essential duties of his employment with
               or without reasonable accommodation for a period aggregating six
               months in any twelve (12) month period; provided that the
               Executive shall be entitled to continue to receive his then
               effective annual salary, in such installments and intervals as
               then payable, less the sum of any payments to which the Executive
               or the Executive's family may then be entitled under Social
               Security, the Company's disability insurance plan, if any, and
               any other source of disability income, for the balance of the
               then remaining term hereunder or six months, whichever is longer,
               but only for so long as the Executive is living; or

          (ii) the Executive's death; provided that the Executive's widow shall
               be entitled to receive payments equal to fifty (50%) percent of
               the Executive's then effective annual salary, less the sum of
               payments 

                                      -8-
<PAGE>
 
               to which the Executive's widow may then be entitled under Social
               Security, and the Company's pension or retirement plans, if any,
               for the balance of the then remaining term hereunder or six (6)
               months, whichever is longer, but only for so long as the
               Executive's widow survives him.

               (F)  Upon the expiration of this Agreement or the sooner
termination of the Executive's employment hereunder, the Executive shall
promptly return all copies of all documents and records reflecting any trade
secrets, confidential information, formulae, proprietary data or other matter
pertaining to the business of the Company, its customers or suppliers, to which
access by the public is restricted, all of which are and shall remain the
Company's property. The Company may withhold any monies due the Executive
hereunder or otherwise until all such property is returned.

          7.   Confidential Information:
               ------------------------ 

          Executive acknowledges that the Company owns, possesses or controls
trade secrets, proprietary information, formulae, methods, products, processes,
data customer lists, sources of supply, and other information pertaining to the
business of the Company (singly and collectively, the "Confidential
Information") , that it may from time to time develop or improve upon such
Confidential Information, and acquire additional Confidential Information,
sometimes from third parties upon the express condition that such Confidential
Information will not be disclosed, that all of such Confidential Information
constitutes a unique and valuable asset of the Company, and that disclosure of
any such Confidential Information to or use by anyone other than in the ordinary
course of the Company's business and for its benefit would result in irreparable
and continuing damage to the Company. The Executive shall keep all such

                                      -9-
<PAGE>
 
Confidential Information and other matters pertaining to the business of the
Company, its customers or Suppliers, which is not generally available to the
public, in strict secrecy and confidence, and shall not at any time during the
term of his employment hereunder, or thereafter for so long as access thereto is
not generally available to the public, directly or indirectly, make use of,
disclose or furnish to any person, firm or Company or other third party any such
Confidential Information, nor participate in the use, disclosure or publication
of any elements thereof, either alone or in conjunction with others, except as
may be required in the ordinary course of the Company's business, or as may be
mandated under applicable law by competent authority.

          8.   Executive Knowledge:
               ------------------- 

               (A)  Executive shall from time to time communicate and make known
to the Company all knowledge possessed by him relating to any methods,
developments, inventions or improvements, whether patented, patentable or
unpatentable, which relate to the business of the Company, whether acquired by
him prior to or during his employment by the Company; provided, however, that
nothing herein shall be construed as requiring any such communication where the
method, development, invention or improvement is lawfully protected from
disclosure as the trade secret of a third party or by any other lawful bar to
such communication existing prior to the commencement of such employment.

               (B)  Any such methods, developments, inventions or improvements,
whether patentable or unpatentable, which Executive may conceive of or develop
while in the Company's employ, shall be and remain the exclusive property 

                                      -10-
<PAGE>
 
of the Company. Executive shall, on request, execute patent applications, and
any other records or memoranda requested by the Company, utilizing,
incorporating or based on any such methods, developments, inventions or
improvements, including instruments deemed necessary by the Company for the
prosecution of any patent application or the acquisition of Letters Patent in
this, any foreign country, or otherwise.

               (C)  Executive shall keep records in connection with his
employment as the Company may from time to time direct, and all such records
shall be the sole and exclusive property of the Company. At any time and from
time to time, within five (5) days after the Company's request, Executive shall
surrender to the Company any and all documents, memoranda, books, papers
letters, price lists, notebooks, reports, logbooks, code books, salesmen
records, customer lists, activity reports, video or audio recordings, computer
programs, any and all data and information, and any and all copies thereof
relating to the Company's business or any Confidential Information.

          9.   Restrictive Covenants:
               --------------------- 

               (A)  The services of Executive are unique, extraordinary and
essential to the business of the Company, particularly in view of Executive's
access to Confidential Information. Accordingly, if the Executive's employment
by the Company shall at any time be terminated for any reason whatsoever (other
than as a result of the Company's failure to make payments due to Executive
hereunder), for a period equal to eighteen (18) months, twelve (12) months if
the Executive's employment is terminated by the Company without Cause or by the
Executive for Good Reason, commencing with

                                      -11-
<PAGE>
 
the date of such termination without the Company's prior written approval, the
Executive shall not, actively or inactively, directly or indirectly, for himself
or for others (i) employ, become employed by, or associate in any business
relationship with any person who was an employee of the Company, or any
business, partnership, association, corporation or other entity which was
affiliated with, or was a customer or supplier of the Company, during the twelve
(12) month period preceding such termination, where such employment, association
or relationship would result in the Executive's being engaged in a commercial
enterprise which competes with or contemplates competing with the Company; nor
(ii) engage in any business which competes or then contemplates competing with
the Company; nor (iii) solicit for competitive purposes any prospective or
existing account of the Company which at the time of such termination was then
actively being solicited by or doing business with the Company; nor (iv)
purposefully affect to the Company's detriment any relationship of the Company
with any customer, supplier or employee of the Company or cause any customer or
supplier to refrain from entrusting additional business to the Company. In the
event that any of the provisions of this Section 8 shall be adjudicated to
exceed the time, geographic or other limitations permitted by applicable law in
any jurisdiction, then such provision shall be deemed reformed in such
jurisdiction to the maximum time, geographic or other limitations permitted by
applicable law.

               (B)  As specifically used in Sections 6, 7 and 8 hereof as well
as in this Agreement throughout, the term "Company" shall mean and include any
parent 

                                      -12-
<PAGE>
 
or subsidiary of the Company, as well as any and all corporations or other
entities as may succeed to all or substantially all of the business or assets of
the Company.

          10.  Injunctive Relief: The Executive acknowledges that the Company's
               ------------------                                              
remedies at law for the breach of any of the confidentiality or other
requirements and restrictive covenants of Sections 6, 7 or 8 of this Agreement
would be inadequate, that the harm to the Company's business likely to arise
from any threatened or actual breach thereof would be material and irreparable,
and, accordingly, that the Company shall be entitled to enforce such
requirements and restrictive covenants by temporary and permanent injunction or
other mandatory remedies restraining the Executive from committing or continuing
any threatened or actual violation of such requirements or restrictive
covenants, without the necessity of proving damages and without prejudice to any
other rights and remedies available to the Company under this Agreement or
otherwise, at law or in equity.

          11.  Notices:  All notices or other communications required or
               -------                                                  
permitted to be given hereunder shall be in writing and shall be deemed
sufficient if delivered against receipt or mailed by registered or certified
mail, return receipt requested, as follows: if to the Company, to its offices at
272 Buffalo Avenue, Freeport, New York 11520, or such other address as the
Company may hereafter designate for that purpose; and if to the Executive, to
him at 9 Gilder Court, Northport, NY  11768, or such other address as he may
hereafter designate for that purpose.

          12.  Binding Effect: This Agreement shall be binding upon and inure to
               ---------------                                                  
the benefit of the legal representatives, successors and permitted assigns of
the 

                                      -13-
<PAGE>
 
parties, including any corporation or other entity into which the Company may
consolidate or merge or to which it may transfer substantially all of its
assets, provided that the rights and obligations of the Executive hereunder
shall not be assignable or delegable without the prior written consent of the
Company.

          13.  Merger: This Agreement is intended as the final and sole
               -------                                                 
expression of the agreement between the parties regarding the subject matter
thereof.  Neither party shall be bound by any representations, promises or
inducements not set forth herein, none of which have been made or relied upon in
the making of this Agreement.  No change, modification, discharge or termination
of any of the provisions of this Agreement or the obligations of either party
thereunder shall be valid unless in writing signed by the parties hereto.

          14.  Waiver: Any waiver by either party hereto of any right, default,
               -------                                                         
terms, conditions, options or remedies hereunder in any one or more instances
shall not thereafter be deemed a waiver of the future enforceability of any such
right or of any subsequent default, or any such term, condition, option or
remedy.

          15.  Severability: The invalidity or unenforceability of any
               -------------                                          
paragraph, term or provision hereof shall in no way affect the validity or
enforceability of the remaining paragraph, terms and provisions thereof.  In any
such event, it is the parties' intention and agreement that any such paragraph,
term or provision which is held or determined to be unenforceable, as written,
shall nonetheless be in force and binding

                                      -14-
<PAGE>
 
to the fullest extent permitted by law as though such paragraph, term or
provision had been written in such a manner and to such an extent as to be
enforceable under the circumstances.  Without limiting the foregoing, with
respect to any confidentiality requirement or restrictive covenant contained
herein, if it is determined that any such provision is excessive as to duration
or scope, it is intended that it nevertheless be enforced for such shorter
duration or with such narrower scope as will render it enforceable.

          16.  Headings:  Headings to paragraphs contained herein are for
               ---------                                                 
reference purposes only and are not to be given any substantive effect or
meaning.

          17.  Governing Law:  This Agreement has been made in the State of New
               --------------                                                  
York, shall be interpreted and construed in accordance with the laws of that
State, without giving effect to conflict of law and principles requiring the
application of the substantive laws of another jurisdiction.

          IN WITNESS WHEREOF, the parties hereunto have duly executed this
Agreement as of the day and year first above written.
