* On February 10, 1997, Johnson & Johnson ("Parent") and INO Acquisition Corp.,
  a wholly owned subsidiary of Parent (the "Purchaser"), entered into a
  Stockholder Agreement (the "Stockholder Agreement") with Chase Venture Capital
  Associates, L.P., CIBC Wood Gundy Ventures, Inc. and Ronald D. Blum, O.D.,
  Chairman, Chief Executive Officer and Secretary of Innotech, Inc.
  (collectively, the "Selling Stockholders"), pursuant to which the Selling
  Stockholders have agreed with Parent and the Purchaser to tender to the
  Purchaser, pursuant to the Offer (as defined below), or sell to the Purchaser
  simultaneously therewith, in each case, at a price of $13.75 per Share, all
  the Shares owned by them (representing an aggregate of 3,331,608 Shares, or
  approximately 37% of the Shares outstanding as of February 10, 1997). In
  addition, any Shares that any such Selling Stockholder may subsequently
  acquire (by exercise of stock options or otherwise) automatically become
  subject to the provisions of the Stockholder Agreement. As of February 10,
  1997, Dr. Blum owned 879,992 options to purchase Shares, 716,856 of which he
  is entitled to exercise within 60 days of February 10, 1997 (without giving
  effect to acceleration of options in connection with the Offer and the
  Merger). The Purchaser's right to purchase the Shares subject to the
  Stockholder Agreement is reflected in Rows 7 and 9 of each of the tables
  above. If the Purchaser accepts for payment and pays for any Shares tendered
  under the Offer and the Minimum Condition (as defined in the Offer) is
  satisfied, the Purchaser must exercise such purchase option at the same time
  as such payment (unless all the Shares subject to the Stockholder Agreement
  have been tendered by the Selling Stockholders and accepted for payment by the
  Purchaser under the Offer). Pursuant to the Stockholder Agreement, each
  Selling Stockholder has also delivered a proxy to the Purchaser to vote, or
  grant a consent or approval in respect of, the Shares subject to the
  Stockholder Agreement against any transaction with a third party other than
  the transactions contemplated by the Offer and the Merger (as defined in the
  Offer). The Stockholder Agreement is described more fully in Section 12
  ("Purpose of the Offer; The Merger Agreement and The Stockholder Agreement")
  of the Offer to Purchase dated February 18, 1997 (the "Offer to Purchase").
  Parent has been informed that the Selling Stockholders intend jointly to file
  a Schedule 13D with respect to the Shares subject to the Stockholder Agreement
  on or about February 18, 1997.

To the Holders of Common Stock
  of Innotech, Inc.
 
INTRODUCTION
 
     INO Acquisition Corp., a Delaware corporation (the "Purchaser") and a
wholly owned subsidiary of Johnson & Johnson, a New Jersey corporation
("Parent"), hereby offers to purchase all outstanding shares (the "Shares") of
Common Stock, par value $0.001 per share, of Innotech, Inc., a Delaware
corporation (the "Company") at $13.75 per Share (the "Offer Price"), net to the
seller in cash, upon the terms and subject to the conditions set forth in this
Offer to Purchase and in the related Letter of Transmittal (which, together with
any amendments or supplements hereto or thereto, collectively constitute the
"Offer").
 
     Tendering stockholders will not be obligated to pay brokerage fees or
commissions or, except as set forth in Instruction 6 of the Letter of
Transmittal, transfer taxes on the purchase of Shares pursuant to the Offer. The
Purchaser will pay all fees and expenses of First Chicago Trust Company of New
York, which is acting as the Depositary (the "Depositary") and Georgeson &
Company Inc., which is acting as Information Agent (the "Information Agent"),
incurred in connection with the Offer. See Section 16.
 
     The Board of Directors of the Company has, by unanimous vote, approved the
Offer and the Merger (as defined below) and determined that the terms of the
Offer and the Merger are fair to, and in the best interests of, the stockholders
of the Company and recommends that stockholders of the Company accept the Offer
and tender their Shares.
 
     Prudential Securities Incorporated, the Company's financial advisor
("Prudential Securities"), has delivered to the Board of Directors of the
Company its written opinion dated February 10, 1997 that, as of such date and
based upon and subject to the matters set forth therein, the cash consideration
to be received by the holders of the Shares in the Offer and the Merger is fair
from a financial point of view to such holders. Such opinion is set forth in
full as an exhibit to the Company's Solicitation/Recommendation Statement on
Schedule 14D-9 (the "Schedule 14D-9"), which is being mailed to stockholders of
the Company concurrently herewith.
 
     The Offer is conditioned upon, among other things, there being validly
tendered and not withdrawn prior to the Expiration Date (as defined in Section
1) (x) that number of Shares which, together with the Shares subject to the
Stockholder Agreement (as defined below) that shall not have been so tendered,
would represent at least a majority of all outstanding Shares (for purposes of
this clause (x) only, "Shares" shall be deemed to refer only to Shares
outstanding as of the date of the Merger Agreement) and (y) that number of
Shares which, together with the Shares subject to the Stockholder Agreement that
shall not have been so tendered, would represent at least a majority of the
fully diluted Shares as of the date of determination (determined on a fully
diluted basis for all outstanding stock options, warrants and any other rights
to acquire Shares) (the conditions in (x) and (y) collectively, the "Minimum
Condition"). The minimum number of Shares that would satisfy the Minimum
Condition (subject to clause (x) above) shall be referred to as the "Minimum
Number of Shares." The Purchaser reserves the right (subject to obtaining the
express written consent of the Company and the applicable rules and regulations
of the Securities and Exchange Commission (the "Commission")), which it
presently has no intention of exercising, to waive or reduce the Minimum
Condition and to elect to purchase, pursuant to the Offer, less than the Minimum
Number of Shares. See Sections 1 and 14.
 
     The Offer is being made pursuant to the Agreement and Plan of Merger dated
as of February 10, 1997 (the "Merger Agreement"), among Parent, the Purchaser
and the Company pursuant to which, following the consummation of the Offer and
the satisfaction of certain conditions, the Purchaser will be merged with and
into the Company, with the Company surviving the merger (as such, the "Surviving
Corporation") to be a wholly owned subsidiary of Parent (the "Merger"). In the
Merger, each outstanding Share not tendered in the Offer (other than Shares
owned by the Company as treasury stock or by Parent, the Purchaser or any other
direct or indirect wholly owned subsidiary of Parent or by stockholders, if any,
who are entitled to and who properly exercise dissenters' rights under Delaware
law) will be converted into the right to receive the per Share price paid in the
Offer in cash, without interest (the "Merger Consideration"). See Section 12.
 
                                        1
<PAGE>   4
 
     The Merger is subject to a number of other conditions, including approval
by stockholders of the Company, if such approval is required by applicable law.
In the event the Purchaser acquires 90% or more of the outstanding Shares
pursuant to the Offer or otherwise, the Purchaser would be able to effect the
Merger pursuant to the short-form merger provisions of the Delaware General
Corporation Law (the "DGCL"), without prior notice to, or any action by, any
other stockholder of the Company. In such event, the Purchaser could, and
intends to, effect the Merger without prior notice to, or any action by, any
other stockholder of the Company. See Section 12.
 
     In connection with the execution of the Merger Agreement, the Purchaser and
Parent entered into a Stockholder Agreement, dated as of February 10, 1997 (the
"Stockholder Agreement"), with Chase Venture Capital Associates, L.P., CIBC Wood
Gundy Ventures, Inc. and Ronald D. Blum, O.D., Chairman, Chief Executive Officer
and Secretary of the Company (collectively, the "Selling Stockholders"),
pursuant to which such Selling Stockholders have agreed to sell to Purchaser,
and Purchaser has agreed to purchase, all 3,331,608 outstanding Shares
beneficially owned by them, representing approximately 37.2% of the outstanding
Shares (31.3% of the Shares on a fully diluted basis), as well as any Shares
subsequently acquired by a Selling Stockholder through the exercise of options
or otherwise, at a price per Share equal to the price paid in the Offer,
provided that such obligation to sell and such obligation to purchase are
subject to the Purchaser having accepted Shares for payment under the Offer and
the Minimum Condition having been satisfied. As of February 10, 1997, Dr. Blum
owned 879,992 options to purchase Shares, 716,856 of which he is entitled to
exercise within 60 days of February 10, 1997 (without giving effect to the
acceleration of options in connection with the Offer and the Merger). Pursuant
to the terms of the Stockholder Agreement, the Purchaser has the right (which it
intends to exercise) to require the Selling Stockholders to tender the Shares
subject to the Stockholder Agreement into the Offer. Pursuant to the Stockholder
Agreement, each Selling Stockholder has also executed and delivered a proxy for
the benefit of the Purchaser with respect to the Shares subject to the
Stockholder Agreement owned by such Selling Stockholder to vote such Shares
against certain competing transactions, as more fully described below under
Section 12.
 
     The Company has informed the Purchaser that, as of February 14, 1997, there
were 8,956,096 Shares issued and outstanding and 1,697,895 Shares reserved for
issuance upon the exercise of outstanding employee stock options and warrants.
Based upon the foregoing, the Purchaser believes that approximately 5,326,996
Shares constitutes a majority of the fully diluted Shares. Johnson & Johnson
Development Corporation ("JJDC"), an affiliate of the Purchaser, beneficially
owns 474,515 Shares, or approximately 5.3% of the outstanding Shares (4.5% of
the Shares on a fully diluted basis). Accordingly, the Minimum Condition will be
satisfied if at least 1,520,873 Shares (other than the outstanding Shares
currently subject to the Stockholder Agreement or owned by JJDC), or
approximately 17.0% of the outstanding Shares (14.3% of the Shares on a fully
diluted basis), are validly tendered and not withdrawn prior to the Expiration
Date. If the Minimum Condition is satisfied and the Purchaser accepts for
payment Shares tendered pursuant to the Offer, including the Shares subject to
the Stockholder Agreement sold pursuant to such agreement or tendered by the
Selling Stockholders pursuant to the Offer, the Purchaser will be able to elect
a majority of the members of the Company's Board of Directors and to effect the
Merger without the affirmative vote of any other stockholder of the Company.
 
     The Merger Agreement and the Stockholder Agreement are more fully described
in Section 12. Certain Federal income tax consequences of the sale of Shares
pursuant to the Offer and the exchange of Shares for the Merger Consideration
pursuant to the Merger are described in Section 5.
 
1.  TERMS OF THE OFFER
 
     Upon the terms and subject to the conditions of the Offer, the Purchaser
will accept for payment and pay for all Shares validly tendered prior to the
Expiration Date and not theretofore withdrawn in accordance with Section 3. The
term "Expiration Date" means 12:00 Midnight, New York City time, on Monday,
March 17, 1997, unless and until the Purchaser shall have extended the period of
time during which the Offer is open, in which event the term "Expiration Date"
shall mean the latest time and date at which the Offer, as so extended by the
Purchaser, shall expire.
 
                                        2
<PAGE>   5
 
     Subject to the terms of the Merger Agreement and the applicable rules and
regulations of the Commission, the Purchaser expressly reserves the right, in
its sole discretion, at any time and from time to time, and regardless of
whether or not any of the events set forth in Section 14 hereof shall have
occurred or shall have been determined by the Purchaser to have occurred, to (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. THE PURCHASER SHALL NOT HAVE ANY OBLIGATION TO PAY INTEREST ON THE
PURCHASE PRICE FOR TENDERED SHARES, WHETHER OR NOT THE PURCHASER EXERCISES ITS
RIGHT TO EXTEND THE OFFER.
 
     If by 12:00 Midnight, New York City time, on Monday, March 17, 1997 (or any
other date or time then set as the Expiration Date), any or all conditions to
the Offer have not been satisfied or waived, the Purchaser reserves the right
(but shall not be obligated), subject to the terms and conditions contained in
the Merger Agreement and to the applicable rules and regulations of the
Commission, to (1) terminate the Offer and not accept for payment any Shares and
return all tendered Shares to tendering stockholders, (2) waive all the
unsatisfied conditions (other than the Minimum Condition and the condition with
respect to the HSR Act (as hereinafter defined)) and, subject to complying with
the terms of the Merger Agreement and the applicable rules and regulations of
the Commission, accept for payment and pay for all Shares validly tendered prior
to the Expiration Date and not theretofore withdrawn, (3) extend the Offer and,
subject to the right of stockholders to withdraw Shares until the Expiration
Date, retain the Shares that have been tendered during the period or periods for
which the Offer is extended or (4) amend the Offer.
 
     There can be no assurance that the Purchaser will exercise its right to
extend the Offer (other than as required by the Merger Agreement). Any
extension, waiver, amendment or termination will be followed as promptly as
practicable by public announcement. In the case of an extension, Rule 14e-l(d)
under the Securities Exchange Act of 1934, as amended (the "Exchange Act"),
requires that the announcement be issued no later than 9:00 a.m., New York City
time, on the next business day after the previously scheduled Expiration Date in
accordance with the public announcement requirements of Rule 14d-4(c) under the
Exchange Act. Subject to applicable law (including Rules 14d-4(c) and 14d-6(d)
under the Exchange Act, which require that any material change in the
information published, sent or given to stockholders in connection with the
Offer be promptly disseminated to stockholders in a manner reasonably designed
to inform stockholders of such change), and without limiting the manner in which
the Purchaser may choose to make any public announcement, the Purchaser will not
have any obligation to publish, advertise or otherwise communicate any such
public announcement other than by making a release to the Dow Jones News
Service.
 
     In the Merger Agreement the Purchaser has agreed that it will not, without
the prior consent of the Company, extend the Offer, except that, without the
consent of the Company, the Purchaser may extend the Offer (1) if at the
Expiration Date any of the conditions to the Purchaser's obligations to accept
Shares for payment are not satisfied or waived, until such time as such
conditions are satisfied or waived, but in no event to a date more than 90
calendar days from the commencement of the Offer, (2) for any period required by
any rule, regulation, interpretation or position of the Commission or the staff
thereof, (3) for a period of up to five business days to permit the Purchaser to
decide whether to modify the Offer in the event of certain competing proposals,
and (4) for an aggregate period of not more than five business days beyond the
latest expiration date that would otherwise be permitted under the terms of the
Merger Agreement as described in this sentence; provided that the aggregate
period of all such extentions may not extend the Expiration Date to a date more
than 90 calendar days from the commencement of the Offer. As used in this Offer
to Purchase, "business day" has the meaning set forth in Rule 14d-1 under the
Exchange Act.
 
     In addition, the Purchaser has agreed in the Merger Agreement that it will
not, without the consent of the Company, (1) reduce the number of Shares subject
to the Offer, (2) reduce the Offer Price, (3) add to or modify the conditions
set forth in Section 14, (4) extend the Offer, except as provided above, (5)
change the form of consideration payable in the Offer or (6) otherwise amend or
alter the Offer in any manner adverse to the Company's stockholders.
 
                                        3
<PAGE>   6
 
     If the Purchaser extends the Offer or if the Purchaser (whether before or
after its acceptance for payment of Shares) is delayed in its acceptance for
payment of or payment for Shares or it is unable to pay for Shares pursuant to
the Offer for any reason, then, without prejudice to the Purchaser's rights
under the Offer, the Depositary may retain tendered Shares on behalf of the
Purchaser, and such Shares may not be withdrawn except to the extent tendering
stockholders are entitled to withdrawal rights as described in Section 3.
However, the ability of the Purchaser to delay the payment for Shares that the
Purchaser has accepted for payment is limited by Rule 14e-1 under the Exchange
Act, which requires that a bidder pay the consideration offered or return the
securities deposited by or on behalf of holders of securities promptly after the
termination or withdrawal of such bidder's offer.
 
     If the Purchaser makes a material change in the terms of the Offer or the
information concerning the Offer or waives a material condition of the Offer
(including, with the Company's consent, a waiver of the Minimum Condition), the
Purchaser will disseminate additional tender offer materials and extend the
Offer to the extent required by Rules 14d-4(c), 14d-6(d) and 14e-l under the
Exchange Act. The minimum period during which an offer must remain open
following material changes in the terms of the Offer or information concerning
the Offer, other than a change in price or a change in the percentage of
securities sought or any dealer solicitation fee, will depend upon the facts and
circumstances then existing, including the relative materiality of the changed
terms or information. With respect to a change in price or a change in the
percentage of securities sought, a minimum period of 10 business days is
generally required to allow for adequate dissemination to stockholders.
 
     Consummation of the Offer is conditioned upon satisfaction of the Minimum
Condition, the expiration or termination of all waiting periods imposed by the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, and the
regulations thereunder (the "HSR Act") and the other conditions set forth in
Section 14. Subject to the terms and conditions contained in the Merger
Agreement, the Purchaser reserves the right (but shall not be obligated) to
waive any or all such conditions.
 
     The Company has provided the Purchaser with the Company's stockholder lists
and security position listings for the purpose of disseminating the Offer to
holders of the Shares. This Offer to Purchase, the related Letter of Transmittal
and other relevant materials will be mailed by the Purchaser to record holders
of Shares and will be furnished by the Purchaser to brokers, dealers, banks,
trust companies and similar persons whose names, or the names of whose nominees,
appear on the stockholder lists or, if applicable, who are listed as
participants in a clearing agency's security position listing, for subsequent
transmittal to beneficial owners of Shares.
 
2.  PROCEDURE FOR TENDERING SHARES
 
     Valid Tender.  For a stockholder validly to tender Shares pursuant to the
Offer, either (1) a properly completed and duly executed Letter of Transmittal
(or facsimile thereof), together with any required signature guarantees and any
other documents required by the Letter of Transmittal, must be received by the
Depositary at one of its addresses set forth on the back cover of this Offer to
Purchase and either certificates for tendered Shares must be received by the
Depositary at one of such addresses or such Shares must be delivered pursuant to
the procedure for book-entry transfer set forth below (and a Book-Entry
Confirmation (as defined below) received by the Depositary), in each case prior
to the Expiration Date, or (2) the tendering stockholder must comply with the
guaranteed delivery procedure set forth below.
 
     The Depositary will establish an account with respect to the Shares at The
Depository Trust Company and the Philadelphia Depository Trust Company (the
"Book Entry Transfer Facilities") for purposes of the Offer within two business
days after the date of this Offer to Purchase. Any financial institution that is
a participant in any of the Book-Entry Transfer Facilities' systems may make
book-entry delivery of Shares by causing a Book-Entry Transfer Facility to
transfer such Shares into the Depositary's account in accordance with such
Book-Entry Transfer Facility's procedures for such transfer. However, although
delivery of Shares may be effected through book-entry transfer into the
Depositary's account at a Book-Entry Transfer Facility, the Letter of
Transmittal (or facsimile thereof), properly completed and duly executed, with
any required signature guarantees and any other required documents, must, in any
case, be transmitted to, and received by,
 
                                        4
<PAGE>   7
 
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 procedure described below. The confirmation
of a book-entry transfer of Shares into the Depositary's account at a Book-Entry
Transfer Facility as described above is referred to herein as a "Book-Entry
Confirmation". DELIVERY OF DOCUMENTS TO A BOOK-ENTRY TRANSFER FACILITY IN
ACCORDANCE WITH SUCH BOOK-ENTRY TRANSFER FACILITY'S PROCEDURES DOES NOT
CONSTITUTE DELIVERY TO THE DEPOSITARY.
 
     THE METHOD OF DELIVERY OF SHARES, THE LETTER OF TRANSMITTAL AND ALL OTHER
REQUIRED DOCUMENTS, INCLUDING DELIVERY THROUGH A 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. 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 if (1) the Letter of Transmittal is signed by the registered holder
of Shares (which term, for purposes of this Section, includes any participant in
any of the Book-Entry Transfer Facilities' systems whose name appears on a
security position listing as the owner of the Shares) 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 (2) such Shares are tendered for the account of a firm
that is a participant in the Security Transfer Agents Medallion Program or the
New York Stock Exchange 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"). In all other cases, all signatures on the 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 issued to a person other than the registered holder of the
certificates surrendered, the tendered certificates must be endorsed or
accompanied by appropriate stock powers, in either case signed exactly as the
name or names of the registered holders or owners appear on the certificates,
with the signatures on the certificates or stock powers guaranteed as aforesaid.
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 procedure 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:
 
          (1) such tender is made by or through an Eligible Institution;
 
          (2) a properly completed and duly executed Notice of Guaranteed
     Delivery substantially in the form provided by the Purchaser is received by
     the Depositary, as provided below, prior to the Expiration Date; and
 
          (3) the certificates for all tendered Shares, in proper form for
     transfer (or a Book-Entry Confirmation with respect to such Shares),
     together with a properly completed and duly executed Letter of Transmittal
     (or facsimile thereof), with any required signature guarantees and any
     other documents required by the Letter of Transmittal, are received by the
     Depositary within five 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, Inc. (the "NYSE") is open for business.
 
     The Notice of Guaranteed Delivery may be delivered by hand to the
Depositary or transmitted by telegram, facsimile transmission or mail to the
Depositary and must include a guarantee by an Eligible Institution in the form
set forth in such Notice of Guaranteed Delivery.
 
     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 (1) certificates for (or a timely Book-Entry
Confirmation with respect to) such Shares, (2) a Letter of Transmittal (or
facsimile thereof), properly completed and duly executed, with any required
signature guarantees, and (3) any other documents
 
                                        5
<PAGE>   8
 
required by the Letter of Transmittal. Accordingly, tendering stockholders may
be paid at different times depending upon when certificates for Shares or
Book-Entry Confirmations are actually received by the Depositary. UNDER NO
CIRCUMSTANCES WILL INTEREST BE PAID ON THE PURCHASE PRICE OF THE SHARES TO BE
PAID BY THE PURCHASER, REGARDLESS OF ANY EXTENSION OF THE OFFER OR ANY DELAY IN
MAKING SUCH PAYMENT.
 
     The valid tender of Shares pursuant to one of the procedures described
above will constitute a binding agreement between the tendering stockholder and
the Purchaser upon the terms and subject to the conditions of the Offer.
 
     Appointment.  By executing a Letter of Transmittal as set forth above, the
tendering stockholder will irrevocably appoint designees of the Purchaser as
such stockholder's attorneys-in-fact and proxies in the manner set forth in the
Letter of Transmittal, each with full power of substitution, to the full extent
of such stockholder's rights with respect to the Shares tendered by such
stockholder and accepted for payment by the Purchaser and with respect to any
and all other Shares or other securities or rights issued or issuable in respect
of such Shares on or after February 10, 1997. All such proxies shall be
considered coupled with an interest in the tendered Shares. Such appointment
will be effective when, and only to the extent that, the Purchaser accepts for
payment Shares tendered by such stockholder as provided herein. Upon such
acceptance for payment, all prior powers of attorney and proxies given by such
stockholder with respect to such Shares or other securities or rights will,
without further action, be revoked and no subsequent powers of attorney and
proxies may be given (and, if given, will not be deemed effective). The
designees of the Purchaser will thereby be empowered to exercise all voting and
other rights with respect to such Shares or other securities or rights in
respect of any annual, special or adjourned meeting of the Company's
stockholders, or otherwise, as they in their sole discretion deem proper. The
Purchaser reserves the right to require that, in order for Shares to be deemed
validly tendered, immediately upon the Purchaser's acceptance for payment of
such Shares, the Purchaser must be able to exercise full voting and other rights
with respect to such Shares and other securities or rights, including voting at
any meeting of stockholders then scheduled.
 
     Determination of Validity.  All questions as to the validity, form,
eligibility, (including time of receipt) and acceptance of any tender of Shares
will be determined by the Purchaser in its sole discretion, which determination
will be final and binding. The Purchaser reserves the absolute right to reject
any or all tenders determined by it not to be in proper form or the acceptance
for payment of or payment for which may, in the opinion of the Purchaser's
counsel, be unlawful. The Purchaser also reserves the absolute right to waive
any defect or irregularity in any tender with respect to any particular Shares,
whether or not similar defects or irregularities are waived in the case of other
Shares. 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
the 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. The
Purchaser's interpretation of the terms and conditions of the Offer (including
the Letter of Transmittal and the instructions thereto) will be final and
binding.
 
     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 provide the Depositary with such stockholder's correct
taxpayer identification number ("TIN") on a Substitute Form W-9 and certify
under penalty of perjury that such TIN is correct and that such stockholder is
not subject to backup withholding. Certain stockholders (including, among
others, all corporations and certain foreign individuals and entities) are not
subject to backup withholding. If a stockholder does not provide its correct TIN
or fails to provide the certifications described above, the Internal Revenue
Service ("IRS") may impose a penalty on such stockholder and payment of cash to
such stockholder pursuant to the Offer may be subject to backup withholding of
31%. All stockholders surrendering Shares pursuant to the Offer should complete
and sign the main signature form and the Substitute Form W-9 included as part of
the Letter or 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). Noncorporate
foreign stockholders should complete and sign the main signature form and a Form
W-8, Certificate of Foreign Status, a copy of which may be obtained from the
Depositary, in order to avoid backup withholding. See Instruction 9 to the
Letter of Transmittal.

3.  WITHDRAWAL RIGHTS
 
     Except as otherwise provided in this Section 3, 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 and paid for by the Purchaser pursuant
to the Offer, may also be withdrawn at any time after April 18, 1997.
 
     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 and
must specify the name of the person having tendered the Shares to be withdrawn,
the number of Shares to be withdrawn and the name of the registered holder of
the Shares to be withdrawn, if different from the name of the person who
tendered the Shares. If certificates for Shares have been delivered or otherwise
identified to the Depositary, then, prior to the physical release of such
certificates, the serial numbers shown on such certificates must be submitted to
the Depositary and, unless such Shares have been tendered by an Eligible
Institution, the signatures on the notice of withdrawal must be guaranteed by an
Eligible Institution. Withdrawals of tenders of Shares may not be rescinded, and
any Shares properly withdrawn will thereafter be deemed not validly tendered for
any purposes of the Offer. However, withdrawn Shares may be retendered by again
following one of the procedures described in Section 2 at any time prior to the
Expiration Date.
 
     All questions as to the form and validity (including time of receipt) of
notices of withdrawal will be determined by the Purchaser in its sole
discretion, which determination will be final and binding. None of the
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
any notice of withdrawal or incur any liability for failure to give any such
notification.
 
4.  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), the 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 3 promptly after the Expiration Date. Any determination
concerning the satisfaction of such terms and conditions will be within the sole
discretion of the Purchaser, and such determination will be final and binding on
all tendering stockholders. See Sections 1 and 14. 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. Any such delays will be
effected in compliance with Rule 14e-1(c) under the Exchange Act (relating to
the Purchaser's obligation to pay for or return tendered Shares promptly after
the termination or withdrawal of the Offer).
 
     Parent will file a Notification and Report Form with respect to the Offer
under the HSR Act. The waiting period under the HSR Act with respect to the
Offer will expire at 11:59 p.m., New York City time, on the 15th day after the
date such form is filed, unless early termination of the waiting period is
granted. In addition, the Antitrust Division of the Department of Justice (the
"Antitrust Division") or the Federal Trade Commission (the "FTC") may extend the
waiting period by requesting additional information or documentary material from
Parent. If such a request is made, such waiting period will expire at 11:59
p.m., New York City time, on the 10th day after substantial compliance by Parent
with such request. See Section 15 hereof for additional information concerning
the HSR Act and the applicability of the antitrust laws to the Offer.
 
     In all cases, payment for Shares accepted for payment pursuant to the Offer
will be made only after timely receipt by the Depositary of (1) certificates for
such Shares (or timely Book-Entry Confirmation of a transfer of such Shares as
described in Section 2), (2) a Letter of Transmittal (or facsimile thereof),
properly completed and duly executed, with any required signature guarantees,
and (3) 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.
 
     For purposes of the Offer, the Purchaser will be deemed to have accepted
for payment, and thereby purchased, Shares properly tendered to the Purchaser
and not withdrawn as, if and when the Purchaser gives
 
                                        7
<PAGE>   10
 
oral or written notice to the Depositary of the Purchaser's acceptance for
payment of such Shares. 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 the Purchaser and transmitting payment to tendering
stockholders. UNDER NO CIRCUMSTANCES WILL INTEREST BE PAID ON THE PURCHASE PRICE
OF THE SHARES TO BE PAID BY THE PURCHASER, REGARDLESS OF ANY EXTENSION OF THE
OFFER OR ANY DELAY IN MAKING SUCH PAYMENT.
 
     If the Purchaser is delayed in its acceptance for payment of or payment for
Shares or is unable to accept for payment or pay for Shares pursuant to the
Offer for any reason, then, without prejudice to the Purchaser's rights under
the Offer (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 the termination or withdrawal of a tender
offer), the Depositary may, nevertheless, on behalf of the Purchaser, retain
tendered Shares, any 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 3.
 
     If any tendered Shares are not purchased pursuant to the Offer because of
an invalid tender or otherwise, certificates for any such Shares will be
returned, without expense to the tendering stockholder (or, in the case of
Shares delivered by book-entry transfer of such Shares into the Depositary's
account at a Book-Entry Transfer Facility pursuant to the procedure set forth in
Section 2, such Shares will be credited to an account maintained at the
appropriate Book-Entry Transfer Facility), as promptly as practicable after the
expiration or termination of the Offer.
 
     The Purchaser reserves the right to transfer or assign, in whole or from
time to time in part, to Parent, or to one or more direct or indirect wholly
owned subsidiaries of Parent, the right to purchase Shares tendered pursuant to
the Offer. but any such transfer or assignment will not relieve the Purchaser of
its obligations under the Offer and will in no way prejudice the rights of
tendering stockholders to receive payment for Shares validly tendered and
accepted for payment pursuant to the Offer.
 
5.  CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
     Sales of Shares pursuant to the Offer (and the receipt of the right to
receive cash by stockholders of the Company pursuant to the Merger) will be
taxable transactions for Federal income tax purposes under the Internal Revenue
Code of 1986, as amended (the "Code"), and may also be taxable transactions
under applicable state, local, foreign and other tax laws. For Federal income
tax purposes, a tendering stockholder will generally recognize gain or loss
equal to the difference between the amount of cash received by the stockholder
pursuant to the Offer (or to be received pursuant to the Merger) and the
aggregate tax basis in the Shares tendered by the stockholder and purchased
pursuant to the Offer (or cancelled pursuant to the Merger). Gain or loss will
be calculated separately for each block of Shares tendered and purchased
pursuant to the Offer (or cancelled pursuant to the Merger).
 
     If tendered Shares are held by a tendering stockholder as capital assets,
gain or loss recognized by the tendering stockholder will be capital gain or
loss, which will be long-term capital gain or loss if the tendering
stockholder's holding period for the Shares exceeds one year. Under present law,
long-term capital gains recognized by a tendering individual stockholder will
generally be taxed at a maximum Federal marginal tax rate of 28%, and long-term
capital gains recognized by a tendering corporate stockholder will be taxed at a
maximum Federal marginal tax rate of 35%.
 
     A stockholder (other than certain exempt stockholders including, among
others, all corporations and certain foreign individuals) that tenders Shares
may be subject to 31% backup withholding unless the stockholder provides its TIN
and certifies that such number is correct or properly certifies that it is
awaiting a TIN. A stockholder that does not furnish its TIN may be subject to a
penalty imposed by the IRS. Each stockholder should complete and sign the
Substitute Form W-9 included as part of the Letter of Transmittal so as to
provide the information and certification necessary to avoid backup withholding.
 
     If backup withholding applies to a stockholder, the Depositary is required
to withhold 31% from payments to such stockholder. Backup withholding is not an
additional tax. Rather, the amount of the backup
 
                                        8
<PAGE>   11
 
withholding can be credited against the Federal income tax liability of the
person subject to the backup withholding, provided that the required information
is given to the IRS. If backup withholding results in an overpayment of tax, a
refund can be obtained by the stockholder upon filing an income tax return.
 
     THE FOREGOING DISCUSSION MAY NOT BE APPLICABLE WITH RESPECT TO SHARES
RECEIVED PURSUANT TO THE EXERCISE OF EMPLOYEE STOCK OPTIONS OR OTHERWISE AS
COMPENSATION OR WITH RESPECT TO HOLDERS OF SHARES WHO ARE SUBJECT TO SPECIAL TAX
TREATMENT UNDER THE CODE, SUCH AS NON-U.S. PERSONS, LIFE INSURANCE COMPANIES,
TAX-EXEMPT ORGANIZATIONS AND FINANCIAL INSTITUTIONS, AND MAY NOT APPLY TO A
HOLDER OF SHARES IN LIGHT OF ITS INDIVIDUAL CIRCUMSTANCES. STOCKHOLDERS ARE
URGED TO CONSULT THEIR OWN TAX ADVISORS TO DETERMINE THE PARTICULAR TAX
CONSEQUENCES TO THEM (INCLUDING THE APPLICATION AND EFFECT OF ANY STATE, LOCAL
OR FOREIGN INCOME AND OTHER TAX LAWS) OF THE OFFER AND THE MERGER.
 
6.  PRICE RANGE OF THE SHARES; DIVIDENDS ON THE SHARES
 
     The Shares are traded in the over-the-counter market and prices are quoted

     On February 10, 1997, the last full day of trading before the public
announcement of the execution of the Merger Agreement, the reported closing sale
price of the Shares on The Nasdaq National Market was $8.875 per Share. On
February 14, 1997, the last full day of trading before the commencement of the
Offer, the reported closing sale price of the Shares on The Nasdaq National
Market was $13.563 per Share. STOCKHOLDERS ARE URGED TO OBTAIN CURRENT MARKET
QUOTATIONS FOR THE SHARES.
 
     According to the Company's Registration Statement on Form S-1 dated March
14, 1996 (the "Company Registration Statement"), since inception the Company has
not declared or paid any dividends on shares of its capital stock.
 
7.  EFFECT OF THE OFFER ON THE MARKET FOR THE SHARES, STOCK QUOTATION AND
    EXCHANGE ACT REGISTRATION
 
     The purchase of Shares pursuant to the Offer will reduce the number of
holders of Shares and the number of Shares that might otherwise trade publicly
and could adversely affect the liquidity and market value of the remaining
Shares held by the public.
 
     Depending upon the number of Shares purchased pursuant to the Offer, the
Shares may no longer meet the requirements of the National Association of
Securities Dealers, Inc. ("NASD") for continued inclusion in The Nasdaq National
Market (the top tier market of The Nasdaq Stock Market), which requires that an
issuer have at least 200,000 publicly held shares, held by at least 400
shareholders or 300 shareholders of round lots, with a market value of
$1,000,000, and have net tangible assets of at least either $1,000,000,
$2,000,000 (depending on profitability levels in two of the issuer's three most
recent fiscal years) or $4,000,000 (depending on profitability levels during
three of the issuer's four most recent fiscal years). If these standards are not
met, the Shares might nevertheless continue to be included in The Nasdaq Stock
Market with quotations published in the Nasdaq "additional list" or in one of
the "local lists", but if the number of holders of the Shares were to fall below
300, or if the number of publicly held Shares were to fall below 100,000 or
 
                                        9
<PAGE>   12
 
there were not at least two registered and active market makers for the Shares,
the NASD's rules provide that the Shares would no longer be "qualified" for
Nasdaq reporting and Nasdaq would cease to provide any quotations. Shares held
directly or indirectly by directors, officers or beneficial owners of more than
10% of the Shares are not considered as being publicly held for this purpose.
According to the Company, as of February 14, 1997, there were approximately 168
holders of record of Shares and 8,956,096 Shares were outstanding. If, as a
result of the purchase of Shares pursuant to the Offer, the Shares no longer
meet the requirements of the NASD for continued inclusion in The Nasdaq Stock
Market or The Nasdaq National Market, as the case may be, the market for Shares
could be adversely affected.
 
     In the event that the Shares no longer meet the requirements of the NASD
for quotation through Nasdaq and the Shares are no longer included in The Nasdaq
Stock Market, it is possible that the Shares would continue to trade in the
over-the-counter market and that price quotations would be reported by other
sources. The extent of the public market for the Shares and the availability of
such quotations would, however, depend upon the number of holders of Shares
remaining at such time, the interests in maintaining a market in Shares on the
part of securities firms, the possible termination of registration of the Shares
under the Exchange Act, as described below, and other factors.
 
     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 neither listed on a national
securities exchange nor held by 300 or more holders of record. Termination of
registration of the Shares under the Exchange Act would, subject to Section
15(d) of the Exchange Act, 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 shortswing profit recovery provisions of Section 16(b) of the
Exchange Act, the requirement of furnishing a proxy or information statement
pursuant to Section 14(a) or (c) of the Exchange Act in connection with
stockholders' meetings and the related requirement of furnishing an annual
report to stockholders and the requirements of Rule 13e-3 under the Exchange Act
with respect to "going private" transactions. Furthermore, the ability of
"affiliates" of the Company and persons holding "restricted securities" of the
Company to dispose of such securities pursuant to Rule 144 or 144A promulgated
under the Securities Act of 1933, as amended, may be impaired or eliminated. The
Purchaser intends to seek to cause the Company to apply for termination of
registration of the Shares under the Exchange Act as soon after the completion
of the Offer as the requirements for such termination are met.
 
     If registration of the Shares is not terminated prior to the Merger, then
the Shares will cease to be reported on The Nasdaq Stock Market and the
registration of the Shares under the Exchange Act will be terminated following
the consummation of the Merger.
 
     The Shares are currently "margin securities" under the regulations of the
Board of Governors of the Federal Reserve System (the "Federal Reserve Board"),
which has the effect, among other things, of allowing brokers to extend credit
on the collateral of the Shares. Depending upon factors similar to those
described above regarding listing and market quotations, it is possible that,
following the Offer, 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. If
registration of Shares under the Exchange Act were terminated, the Shares would
no longer be "margin securities" or be eligible for Nasdaq reporting.

10.  SOURCE AND AMOUNT OF FUNDS
 
     The total amount of funds required by the Purchaser to purchase all
outstanding Shares pursuant to the Offer and to pay fees and expenses related to
the Offer and the Merger is estimated to be approximately $130 million. The
Purchaser plans to obtain all funds needed for the Offer and the Merger through
a capital contribution which will be made by Parent to the Purchaser. Parent
will fund such contribution from available working capital. The Purchaser
therefore has not conditioned the Offer on obtaining financing.
 
11.  CONTACTS WITH THE COMPANY; BACKGROUND OF THE OFFER
 
     Since February 1993, Parent and the Company have from time to time engaged
in discussions and exchanges of information in an effort to examine possible
business arrangements.
 
     In August 1995, as part of a series of transactions aimed at providing the
Company with necessary financing, JJDC purchased $1,500,000 of preferred stock
in the Company. In addition, concurrently therewith, Parent acquired an option
(the "Option") to purchase all of the outstanding capital stock of the Company
at a net aggregate exercise price of approximately $85 million. Parent paid the
Company $1,500,000 in consideration for the grant of the Option. Due to certain
business considerations, Parent did not exercise the Option, and pursuant to its
terms, the Option terminated on March 14, 1996, and Parent was issued additional
preferred stock in lieu thereof.
 
     Parent conducted due diligence investigations of the Company during the
fall and winter of 1995-1996 in connection with the Option, and Parent, Johnson
& Johnson Vision Products, Inc. and the Company entered into a Confidentiality
Agreement (the "Confidentiality Agreement") in connection therewith on November
27, 1995.
 
     As a result of the transactions immediately preceding the Company's initial
public offering on March 14, 1996, the equity securities owned by Parent and its
subsidiaries were converted into an aggregate of 474,515 Shares.
 
     On August 1, 1996 and January 31, 1997, the Confidentiality Agreement was
restated and amended, and Parent conducted a new due diligence review of the
Company in contemplation of a possible business arrangement. During January,
1997, Parent decided to propose a transaction to the Company whereby Parent
would acquire all the outstanding capital stock of the Company for cash.
 
     On January 29, 1997, James R. Utaski, Vice President, Corporate Development
of Parent, W. Ben Deibler, Vice President, New Business Development, Worldwide
Vistakon Franchise, a division of a subsidiary of Parent and James R. Hilton,
Assistant General Counsel of Parent, met in New York with Ronald D. Blum, O.D.,
Chairman, Chief Executive Officer and Secretary of the Company, Damion E.
Wicker, M.D., a director of the Company and a general partner of the general
partner of Chase Venture Capital Associates, L.P., Ian M. Kidson, a director of
the Company and a Managing Director of CIBC Wood Gundy Securities Inc., and
counsel to the Company. At the meeting, Messrs. Utaski, Deibler and Hilton
expressed Parent's serious interest in exploring an acquisition of the Company
and proposed general parameters pursuant to which Parent would be willing to
proceed with such a transaction. The representatives of the Company expressed
the Company's interest in proceeding with discussions.
 
     On January 30, 1997, the same parties continued negotiations by telephone
conference.
 
     On February 2, 1997, the same parties other than Mr. Hilton met again in
New York. Mr. Deibler indicated that Parent was prepared to proceed with an
acquisition of the Company valued between approximately $130 and $134 million,
subject to the accuracy of certain assumptions (including the amount of cash and
equivalents and usable net operating loss carryforwards) and subject to
completion of due diligence and the negotiation of definitive agreements. On
this basis, Dr. Blum agreed on behalf of the Company to move forward to consider
whether to effect a transaction with Parent.
 
                                       13
<PAGE>   16
 
     Following the February 2, 1997, meeting, Parent began a new extensive due
diligence review of the Company. Also, on February 2, 1997, the Company's Board
of Directors resolved to create a Special Committee to explore various strategic
alternatives for the Company, including a possible transaction with Parent.
 
     On February 5, 1997, Messrs. Utaski and Deibler met in New York with
counsel for Parent and the Company, Michael B. Packard and Gregory J. Forrest,
each a director of the Company and a member of its Special Committee, counsel to
the Special Committee and representatives of Prudential Securities. Parent's
representatives confirmed that it was a condition to Parent's willingness to
enter into an agreement to acquire the Company that there be an agreement along
the lines of the Stockholder Agreement and that there be certain other
provisions in the event of the termination of the Merger Agreement by the
Company in connection with a competing transaction. The members of the Special
Committee and their representatives discussed with Parent and its
representatives the details of such provisions as well as certain other
provisions of the draft documents that had been circulated.
 
     Between February 5, 1997, and February 10, 1997, Parent, the Company, the
Special Committee and their respective representatives had several internal
discussions and continued negotiations with respect to the price, the amount and
terms of the Termination Fee and other details of the transaction. On February
9, 1997, the Special Committee met with its counsel, representatives of
Prudential Securities and Company counsel and reviewed and discussed the
proposed transaction, including drafts of the Merger Agreement and related
documents. After various proposals and counterproposals, these negotiations
culminated in the Special Committee recommending to the Company's Board of
Directors during its Board Meeting on February 10, 1997, Parent's proposed price
of $13.75 per Share and forms of definitive agreements, and the Company and
Parent agreeing on such price and documentation. The Company's full Board of
Directors met midday on Monday, February 10, 1997. Following a presentation of
Prudential Securities, the Company's receipt of the fairness opinion from
Prudential Securities and discussions with counsel to the Company and to its
Special Committee concerning the terms of the Offer and the Merger and the
fiduciary duties of the Company's directors, the Special Committee met
separately and determined to recommend to the full Board approval of the
proposed transaction. Thereafter, the full Board reconvened and, after receiving
the Special Committee's recommendation, approved the transaction. Parent's Board
of Directors also met Monday, February 10, 1997, during which meeting the
transactions contemplated by the Merger Agreement and Stockholder Agreement were
approved. Following these approvals, the Merger Agreement and Stockholder
Agreement were executed, and the transaction was publicly announced before
financial markets opened on February 11, 1997.
 
12.  PURPOSE OF THE OFFER; THE MERGER AGREEMENT AND THE STOCKHOLDER AGREEMENT
 
     Purpose.  The purpose of the Offer is to acquire control of and the entire
equity interest in the Company. Following the Offer, the Purchaser and Parent
intend to acquire any remaining equity interest in the Company not acquired in
the Offer by consummating the Merger.
 
     The Merger Agreement.  The Merger Agreement provides that following the
satisfaction of the conditions described below under "Conditions to the Merger",
the Purchaser will be merged with and into the Company, and each then
outstanding Share (other than Shares owned by the Company as treasury stock or
by Parent, the Purchaser or any other direct or indirect wholly owned subsidiary
of Parent or by stockholders, if any, who are entitled to and who property
exercise dissenters' rights under Delaware law), will be converted into the
right to receive an amount in cash equal to the price per Share paid pursuant to
the Offer.
 
     VOTE REQUIRED TO APPROVE MERGER.  The DGCL requires, among other things,
that the adoption of any plan of merger or consolidation of the Company must be
approved by the Board of Directors and generally by the holders of the Company's
outstanding voting securities. The Board of Directors of the Company has
approved the Offer and the Merger; consequently, the only additional action of
the Company that may be necessary to effect the Merger is approval by such
stockholders if the "short-form" merger procedure described below is not
available. Under the DGCL, the affirmative vote of holders of a majority of the
outstanding Shares (including any Shares owned by the Purchaser), is generally
required to approve the Merger. If the Purchaser acquires, through the Offer or
otherwise, voting power with respect to at least a majority of the outstanding
Shares (which would be the case if the Minimum Condition were satisfied and the
Purchaser were to accept for payment Shares tendered pursuant to the Offer,
including the Shares subject to
 
                                       14
<PAGE>   17
 
the Stockholder Agreement sold pursuant to the Stockholder Agreement or tendered
by the Selling Purchaser were to accept for payment Shares tendered pursuant to
the Offer, including the Shares subject to the Stockholder Agreement sold
pursuant to the Stockholder Agreement or tendered by the Selling Stockholders
pursuant to the Offer), it would have sufficient voting power to effect the
Merger without the vote of any other stockholder of the Company. However, the
DGCL also provides that if a parent company owns at least 90% of each class of
stock of a subsidiary, the parent company can effect a short-form merger with
that subsidiary without the action of the other stockholders of the subsidiary.
Accordingly, if, as a result of the Offer or otherwise, the Purchaser acquires
or controls the voting power of at least 90% of the outstanding Shares, the
Purchaser could, and intends to, effect the Merger without prior notice to, or
any action by, any other stockholder of the Company.
 
     CONDITIONS TO THE MERGER.  The Merger Agreement provides that the Merger is
subject to the satisfaction of certain conditions, including the following: (1)
if applicable, the Merger Agreement having been approved and adopted by the
affirmative vote of the Company's stockholders by the requisite vote in
accordance with applicable law and the Company's certificate of incorporation
and (2) no statute, rule, regulation, executive order, decree, temporary
restraining order, preliminary or permanent injunction or other order issued by
any court of competent jurisdiction or other legal restraint or prohibition
preventing the consummation of the Merger being in effect; provided, however,
that each of the Company, the Purchaser and Parent has used reasonable efforts
to prevent the entry of any such injunction or other order and to appeal as
promptly as possible any injunction or other order that may be entered.
 
     TERMINATION OF THE MERGER AGREEMENT.  The Merger Agreement may be
terminated at any time prior to the Effective Time, whether before or after
approval by the stockholders of the Company, (1) by mutual written consent of
the Company and Parent, (2) by either the Company or Parent if (a)(i) as a
result of any of the conditions to the Offer not being satisfied, the Offer
shall have been terminated or expired in accordance with its terms without the
Purchaser having accepted for payment any Shares pursuant to the Offer or (ii)
the Purchaser shall not have accepted for payment any Shares pursuant to the
Offer by May 31, 1997, unless the failure of any condition to such acceptance
results from the failure by the party seeking to terminate the Merger Agreement
to perform any of its obligations under the Merger Agreement from facts or
circumstances that constitute a material breach of representation or warranty
under the Merger Agreement by such party unless such breach was not willful or
intentional; or (b) if any Federal, state or local government or any court,
tribunal, administrative agency or commission or other regulatory authority or
agency, domestic, foreign or supranational (a "Governmental Entity"), shall have
issued an order, decree or ruling or taken any action permanently enjoining,
restraining or otherwise prohibiting the acceptance for payment of or payment
for Shares pursuant to the Offer or the Merger and such order, decree or ruling
or other action has become final and nonappealable, (3) by Parent or the
Purchaser prior to the Purchaser's obligation to accept Shares for payment
pursuant to the Offer, in the event of a breach by the Company of any
representation, warranty, covenant or other agreement contained in the Merger
Agreement which (i) would give rise to the failure of a condition set forth in
paragraph (d) or (e) under Section 14 and (ii) cannot be or has not been cured
within 20 days after the giving of written notice to the Company, (4) by Parent
or the Company if, prior to the obligation of the Purchaser to accept Shares for
payment pursuant to the Offer, the Board of Directors of the Company determines
that a Takeover Proposal (as hereinafter defined) constitutes a Superior
Proposal (as hereinafter defined), provided it has complied with certain
additional provisions as described in the second paragraph under "Takeover
Proposals", including in the case of a termination by the Company, making
payment of the Expenses and Termination Fee (each as defined below under "Fees
and Expenses"), and (5) by the Company if Parent or the Purchaser shall have (A)
failed to commence the Offer within five business days of the date of the Merger
Agreement, (B) failed to pay for Shares pursuant to the Offer in accordance with
the terms of the Merger Agreement or (C) breached in any material respect any of
their respective representations, warranties, covenants or other agreements
contained in the Merger Agreement, which failure to perform in respect of clause
(C) is incapable of being cured or has not been cured within 20 days after the
giving of written notice to Parent or the Purchaser, except in any case under
clause (C), such failures which are not reasonably likely to affect adversely
Parent's or the Purchaser's ability to complete the Offer or the Merger.
 
                                       15
<PAGE>   18
 
     TAKEOVER PROPOSALS.  The Merger Agreement provides that the Company shall
not, and shall not authorize or permit any of its officers, directors or
employees or any investment banker, financial advisor, attorney, accountant or
other representative retained by it to, directly or indirectly, (i) solicit,
initiate or encourage (including by way of furnishing information), or take any
other action to facilitate, any inquiries or the making of any proposal that
constitutes, or may reasonably be expected to lead to, any Takeover Proposal or
(ii) participate in any discussions or negotiations regarding any Takeover
Proposal; provided, however, that if, at any time prior to the acceptance for
payment of Shares pursuant to and subject to the conditions (including the
Minimum Condition) of the Offer, the Board of Directors of the Company (or its
Special Committee) determines in good faith, after consultation with outside
counsel, that failure to do so would create a substantial risk of liability for
breach of its fiduciary duties to the Company's stockholders under applicable
law, the Company may, in response to a Takeover Proposal that was unsolicited,
and subject to compliance with the notification provisions discussed below, (x)
furnish information with respect to the Company to any person pursuant to a
customary and reasonable confidentiality agreement and (y) participate in
negotiations regarding such Takeover Proposal. The Merger Agreement defines
"Takeover Proposal" as any proposal or offer from any person relating to any
direct or indirect acquisition or purchase of 20% or more of the assets of the
Company or 20% or more of any class of outstanding equity securities of the
Company, any tender offer or exchange offer that if consummated would result in
any person beneficially owning 20% or more of any class of equity securities of
the Company or any merger, consolidation, business combination, sale of
substantially all the assets, recapitalization, liquidation, dissolution or
similar transaction involving the Company, other than the transactions
contemplated by Merger Agreement.
 
     The Merger Agreement provides further that unless the Board of Directors of
the Company shall have terminated the Merger Agreement as described below,
neither the Board of Directors of the Company nor any committee thereof shall
(i) withdraw or modify, or propose to withdraw or modify, in a manner adverse to
Parent, the approval or recommendation by such Board of Directors or any such
committee of the Offer, the Merger Agreement or the Merger, (ii) approve or
recommend, or propose to approve or recommend, any Takeover Proposal or (iii)
enter into any letter of intent, agreement in principle, acquisition agreement
or other agreement (an "Acquisition Agreement") with respect to any Takeover
Proposal. Notwithstanding the foregoing, the Board of Directors of the Company
or any committee thereof may take any such action if, prior to the obligation of
the Purchaser to accept Shares for payment pursuant to the Offer, (x) the Board
of Directors of the Company determines that a Takeover Proposal constitutes a
Superior Proposal (as defined below) and (y) the Board of Directors of the
Company terminates the Merger Agreement; provided, however, that the Company may
not terminate the Merger Agreement pursuant to this provision unless and until
five business days have elapsed following delivery to Parent of a written notice
of such determination by the Board of Directors of the Company and during such
five business day period the Company (i) informs Parent of the terms and
conditions of the Takeover Proposal and the identity of the person making the
Takeover Proposal and (ii) otherwise cooperates with Parent with respect thereto
(subject, in the case of this clause (ii), to the condition that the Board of
Directors of the Company shall not be required to take any action that it
believes, after consultation with outside legal counsel, would present a
substantial risk of liability for violating its obligations to the Company or
the Company's stockholders under applicable law) with the intent of enabling
Parent to agree to a modification of the terms and conditions of the Merger
Agreement so that the transactions contemplated hereby may be effected;
provided, further, that the Company may not terminate the Merger Agreement
pursuant to such provision unless at the end of such five business day period
the Board of Directors of the Company continues to believe that the Takeover
Proposal constitutes a Superior Proposal and no later than two days thereafter
the Company pays to Parent the Expenses and the Termination Fee; and provided,
further, that in the event the determination of the Board of Directors of the
Company that a Takeover Proposal constitutes a Superior Proposal is made less
than ten business days prior to the scheduled expiration of the Offer, Parent
and the Purchaser will either (x) reduce the five business day period or (y)
extend the Offer, in either case such that the five business day period
described above will end no later than five business days prior to the
expiration of the Offer. The Merger Agreement defines a "Superior Proposal" to
be any bona fide proposal made by a third party to acquire, directly or
indirectly, for consideration consisting of cash and/or securities, more than
50% of the voting power of the Shares of or all or substantially all the assets
of the Company and otherwise on terms which the Board of Directors of the
Company determines in its good faith
 
                                       16
<PAGE>   19
 
judgment (based on the written opinion of a financial advisor of nationally
recognized reputation (which opinion shall be provided to Parent)) to be more
favorable to the Company's stockholders than the Offer and the Merger and for
which financing, to the extent required, is then committed or which, in the good
faith judgment of the Board of Directors of the Company, is capable of being
obtained by such third party.
 
     In addition to the obligations of the Company set forth in the preceding
paragraph, the Merger Agreement provides that the Company shall immediately
advise Parent orally and in writing of any request for information or of any
Takeover Proposal or any inquiry regarding the making of a Takeover Proposal,
the material terms and conditions of such request, Takeover Proposal or inquiry,
and the identity of the person making any such Takeover Proposal or inquiry. The
Company is further required under the terms of the Merger Agreement to keep
Parent fully informed of the status and details (including amendments or
proposed amendments) of any such request, Takeover Proposal or inquiry.
 
     The Merger Agreement provides that nothing contained therein shall prohibit
the Company from taking and disclosing to its stockholders a position
contemplated by Rule 14e-2(a) promulgated under the Exchange Act or from making
any disclosure to the Company's stockholders if, in the opinion of the Board of
Directors of the Company, after consultation with counsel, failure to so
disclose would be inconsistent with its fiduciary duties to the Company's
stockholders under applicable law; provided that the Company does not, except as
permitted by the Merger Agreement, withdraw or modify, or propose to withdraw or
modify, its position with respect to the Offer or the Merger or approve or
recommend, or propose to approve or recommend, a Takeover Proposal; provided,
further, that the taking of a position by the Company pursuant to Rule
14e-2(a)(2) or (3) of the Exchange Act in respect of a Takeover Proposal shall
not be deemed a withdrawal, a modification or a proposal to do either, of its
position with respect to the Offer or the Merger for purposes thereof.
 
     FEES AND EXPENSES.  The Merger Agreement provides that in the event that
the Merger Agreement is terminated by any party thereto pursuant to the
procedures described in the second paragraph under "Takeover Proposals", the
Company shall promptly, but in no event later than two days after the date of
such termination, pay Parent a fee equal to $6.25 million in immediately
available funds (the "Termination Fee") and all Expenses (as defined below). The
Merger Agreement further provides that if, at the time of any other termination
of the Merger Agreement (with certain exceptions as set forth in the Merger
Agreement), a Takeover Proposal shall have been made (other than a Takeover
Proposal made solely to a Selling Stockholder unless and until such Takeover
Proposal becomes known to the Company (other than knowledge imputed to the
Company by virtue of a direct relationship of such Stockholder with an officer
or director of the Company) or becomes publicly known) and prior to December 31,
1997 the Company shall either (x) consummate a Trigger Takeover Proposal (as
hereinafter defined) or (y) enter into an Acquisition Agreement providing for a
Trigger Takeover Proposal, then the Company shall pay the Termination Fee and
all Expenses in the case of clause (x) concurrently with the consummation of
such Trigger Takeover Proposal or in the case of clause (y) concurrently with
the consummation of the transaction subject to such Acquisition Agreement
(whether or not such transaction is consummated prior to December 31, 1997);
provided, however, that no Termination Fee and no Expenses will be payable
pursuant to this sentence if the Offer is terminated prior to its scheduled
expiration date (without giving effect to any voluntary or required extensions
thereof) or if at the time the Merger Agreement is terminated, the Minimum
Condition shall have been satisfied but any of the other conditions to the Offer
shall not have been satisfied. The Merger Agreement defines "Trigger Takeover
Proposal" to be a Takeover Proposal except that references to "20%" in the
definition of "Takeover Proposal" shall be deemed to be references to "40%" and
a Trigger Takeover Proposal may only be in the form of a single transaction or a
series of related transactions. The Merger Agreement defines "Expenses" to be
all out-of-pocket expenses incurred by Parent and the Purchaser in connection
with the Merger Agreement, the Stockholder Agreement and the transactions
contemplated thereby in an amount not to exceed $500,000, payable in immediately
available funds.
 
     CONDUCT OF BUSINESS BY THE COMPANY.  The Merger Agreement provides that
during the term of the Merger Agreement, the Company shall carry on its business
in the ordinary course and use all reasonable efforts to preserve intact its
current business organization, keep available the services of its current
officers and employees and preserve its relationships with customers, suppliers,
licensors, licensees, distributors and others having business dealings with it.
The Merger Agreement further provides that, except as otherwise expressly
 
                                       17
<PAGE>   20
 
contemplated by the Merger Agreement, the Company shall not (without Parent's
prior written consent) (1) (a) declare, set aside or pay any dividends on, or
make any other distributions in respect of, any of its capital stock, (b) split,
combine or reclassify any of its capital stock or issue or authorize the
issuance of any other securities in respect of, in lieu of or in substitution
for shares of its capital stock or (c) purchase, redeem or otherwise acquire any
shares of capital stock of the Company or any other securities thereof or any
rights, warrants or options to acquire any such shares or other securities; (2)
issue, deliver, sell, pledge or otherwise encumber any shares of its capital
stock, any other voting securities or any securities convertible into, or any
rights, warrants or options to acquire, any such shares, voting securities or
convertible securities (other than the issuance of Shares upon the exercise of
employee stock options outstanding on the date of the Merger Agreement in
accordance with their present terms); (3) amend its certificate of incorporation
or by-laws; (4)(a) acquire or agree to acquire (i) by merging or consolidating
with, or by purchasing a substantial portion of the assets of, or by any other
manner, any business or any corporation, partnership, joint venture, association
or other business organization or division thereof or (ii) any assets that are

ordinary course of business to fund or in any other way secure the payment of

     Pursuant to the Merger Agreement, the Company shall not take any action
that could reasonably be expected to result in (1) any of its representations
and warranties set forth in the Merger Agreement that are qualified as to
materiality becoming untrue, (2) any of such representations and warranties that
are not so
 
                                       18
<PAGE>   21
 
qualified becoming untrue in any material respect or (3) except as otherwise
permitted by the provisions of the Merger Agreement described above under
"Takeover Proposals", any of the conditions to the Offer or to the Merger not
being satisfied.
 
     BOARD OF DIRECTORS.  The Merger Agreement provides that promptly upon the
acceptance for payment of, and payment for, any Shares by the Purchaser pursuant
to the Offer, the Purchaser shall be entitled to designate such number of the
directors on the Board of Directors of the Company such that the Purchaser,
subject to compliance with Section 14(f) of the Exchange Act, will control a
majority of such directors, and the Company and its Board of Directors shall, at
such time, take all such action needed to cause the Purchaser's designees to be
appointed to the Company's Board of Directors. Subject to applicable law, the
Company has agreed to take all action requested by Parent necessary to effect
any such election, including mailing to its stockholders the Information
Statement containing the information required by Section 14(f) of the Exchange
Act and Rule 14f-1 promulgated thereunder, which Information Statement is
attached as Schedule I to the Schedule 14D-9.
 
     STOCK OPTIONS.  The Merger Agreement provides that as soon as practicable
following the date of the Merger Agreement but in no event later than the
consummation of the Offer, the Company (or, if appropriate, the Board of
Directors of the Company or any committee administering the Stock Option Plans
(as defined below)) shall (including by adopting resolutions or taking any other
actions) ensure that, with certain exceptions, each outstanding option to
purchase Shares (a "Company Stock Option") granted under any stock option, stock
appreciation rights or stock purchase plan, program or arrangement of the
Company (collectively, the "Stock Option Plans") and each outstanding warrant to
purchase Shares (a "Warrant") in each case outstanding immediately prior to the
consummation of the Offer, whether or not then exercisable, shall either (x) be
cancelled immediately prior to the effective time of the Merger (the "Effective
Time") in exchange for an amount in cash, payable at the time of such
cancellation, equal to the product of (y) the number of Shares subject to such
Company Stock Option or Warrant immediately prior to the Effective Time and (z)
the excess of the price per Share to be paid in the Offer over the per Share
exercise price of such Company Stock Option or Warrant (the "Net Amount") or (y)
be converted immediately prior to the Effective Time into the right solely to
receive the Net Amount; provided, however, that no such cash payment has been
made. The Merger Agreement further provides that the Company (or, if
appropriate, the Board of Directors of the Company or any committee
administering the Stock Option Plans) shall use its reasonable best efforts to
ensure that immediately prior to the Effective Time the Company Stock Options
and Warrants remaining are cancelled or converted as set forth above. The
Company shall not make, or agree to make, any payment of any kind to any holder
of a Company Stock Option or a Warrant (except for the payment described above)
without the consent of Parent (which consent will not be unreasonably withheld).
 
     The Merger Agreement provides further that subject to the provisions set
forth above, all Stock Option Plans shall terminate as of the Effective Time and
the provisions in any other benefit plan providing for the issuance, transfer or
grant of any capital stock of the Company or any interest in respect of any
capital stock of the Company shall be deleted as of the Effective Time. The
Merger Agreement provides that the Company shall ensure that following the
consummation of the Offer (with certain exceptions), no holder of a Company
Stock Option or Warrant or any participant in any Stock Option Plan shall have
any right thereunder to acquire any capital stock of the Company, Parent or the
Surviving Corporation, and that the Company shall use its reasonable best
efforts to ensure that following the Effective Time, no holder of any remaining
Company Stock Option or Warrant or any participant in any Stock Option Plan
shall have any right thereunder to acquire any capital stock of the Company,
Parent or the Surviving Corporation. The Merger Agreement also provides that the
Surviving Corporation shall continue to be obligated to pay the Net Amount to
holders of any Company Stock Options or Warrants converted in accordance with
clause (y) of the immediately preceding paragraph.
 
     BENEFIT PLANS.  Parent has agreed in the Merger Agreement to cause the
Surviving Corporation to take such actions as are necessary so that, for a
period of not less than one year after the Effective Time, employees of the
Company who continue their employment after the Effective Time will be provided
employee benefits which in the aggregate are at least generally comparable to
those provided to such employees in effect on the date of the Merger Agreement.
The Merger Agreement also provides that it is Parent's current intention,
 
                                       19
<PAGE>   22
 
following the first anniversary of the Effective Time, to provide employee
benefit plans, programs, arrangements and policies for the benefit of employees
of the Company which are generally comparable in the aggregate to the employee
benefit plans, programs arrangements and policies provided for the benefit of
other similarly situated employees of Parent and its subsidiaries.
 
     INDEMNIFICATION, EXCULPATION AND INSURANCE.  Parent has agreed in the
Merger Agreement that all rights to indemnification and exculpation (including
the advancement of expenses) from liabilities for acts or omissions occurring at
or prior to the Effective Time (including with respect to the transactions
contemplated by the Merger Agreement) existing now or at the Effective Time in
favor of the current or former directors or officers of the Company as provided
in its certificate of incorporation, its by-laws (each as in effect on the date
of the Merger Agreement) and reasonable indemnification agreements shall be
assumed by the Surviving Corporation in the Merger, without further action, as
of the Effective Time and shall survive the Merger and shall continue in full
force and effect without amendment, modification or repeal in accordance with
their terms for a period of not less than six years after the Effective Time;
provided however, that if any claims are asserted or made within such six year
period, all rights to indemnification (and to advancement of expenses) hereunder
in respect of any such claims shall continue, without diminution, until
disposition of any and all such claims.
 
     The Merger Agreement provides that, unless Parent agrees to guarantee the
indemnification obligations described in the preceding paragraph, for a period
of six years from the Effective Time, Parent shall provide officers' and
directors' liability insurance in respect of acts or omissions occurring at or
prior to the Effective Time, including but not limited to the transactions
contemplated by, the Merger Agreement, covering each person currently covered by
the Company's officers' and directors' liability insurance policy, or who
becomes covered by such policy prior to the Effective Time, on terms with
respect to coverage and amount no less favorable than those of such policy in
effect on the date hereof, provided that in satisfying such obligation Parent
shall not be obligated to pay premiums in excess of 200% of the amount per annum
the Company paid in its last full fiscal year (which the Company has represented
to Parent and the Purchaser to be $129,000), and provided further that Parent
shall nevertheless be obligated to provide such coverage as may be obtained for
such 200% amount.
 
     The Merger Agreement provides that in the event Parent, the Surviving
Corporation or any of their successors or assigns (i) consolidates with or
merges into any other person and shall not be the continuing or surviving
corporation or entity of such consolidation or merger or (ii) transfers all or
substantially all of its properties and assets to any person, then and in each
such case, proper provisions shall be made so that the successors and assigns of
Parent or the Surviving Corporation, as the case may be, shall assume the
obligations set forth in the preceding paragraphs. The Merger Agreement also
provides that, in the event the Surviving Corporation transfers any material
portion of its assets, in a single transaction or in a series of transactions,
Parent will either guarantee the indemnification obligations set forth in the
preceding paragraphs or take such other action to ensure that the ability of the
Surviving Corporation to satisfy such indemnification obligations will not be
diminished in any material respect.
 
     REASONABLE EFFORTS.  The Merger Agreement provides that, on the terms and
subject to the conditions of the Merger Agreement, each of the parties will use
all reasonable efforts to take, or cause to be taken, all actions, and to do, or
cause to be done, and to assist and cooperate with the other parties in doing,
all things necessary, proper or advisable to consummate and make effective, in
the most expeditious manner practicable, the Offer and the Merger and the other
transactions contemplated by the Merger Agreement and the Stockholder Agreement.
 
     REPRESENTATIONS AND WARRANTIES.  The Merger Agreement contains various
customary representations and warranties.
 
     PROCEDURE FOR TERMINATION, AMENDMENT, EXTENSION OR WAIVER.  The Merger
Agreement provides that in the event the Purchaser's designees are appointed or
elected to the Board of Directors of the Company as described above under "Board
of Directors", after the acceptance for payment of Shares pursuant to the Offer
and prior to the Effective Time of the Merger, the affirmative vote of the
directors of the Company not designated by Parent or the Purchaser is required
for the Company to amend or terminate the Merger Agreement, exercise or waive
any of its rights or remedies under the Merger Agreement, extend the time for
 
                                       20
<PAGE>   23
 
performance of the Purchaser's and Parent's respective obligations under the
Merger Agreement or take any action to amend or otherwise modify the Company's
certificate of incorporation or by-laws.
 
     Stockholder Agreement.  The Stockholder Agreement provides that each
Selling Stockholder will sell, and the Purchaser will purchase, all Shares
beneficially owned by such Selling Stockholder, at a price per Share equal to
$13.75. Such obligations to sell and to purchase are subject to the Purchaser
having accepted Shares for payment under the Offer and the Minimum Condition
having been satisfied. The Stockholder Agreement also provides that each Selling
Stockholder may, and at the request of Parent shall, tender its Shares subject
to the Stockholder Agreement in the Offer. Any Shares of any Selling Stockholder
not purchased in the Offer will be purchased at the same time as payment is made
pursuant to the Offer.
 
     Each of the Selling Stockholders has agreed, until the Stockholder
Agreement has terminated, among other things, not to: (i) sell, transfer, give,
pledge or otherwise dispose of, or enter into any contract, option or other
arrangement with respect to the sale, transfer, pledge, assignment or other
disposition of, the Shares subject to the Stockholder Agreement owned by such
Selling Stockholder other than pursuant to the terms of the Offer or the Merger;
(ii) enter into any voting arrangement, whether by proxy, voting agreement or
otherwise, in connection with, directly or indirectly, any Takeover Proposal;
(iii) directly or indirectly solicit, initiate or encourage the submission of,
any Takeover Proposal; or (iv) directly or indirectly participate in any
discussions or negotiations regarding, or furnish to any person any information
with respect to, or take any other action to facilitate any inquiries or the
making of any proposal that constitutes, or may reasonably be expected to lead
to, any Takeover Proposal; provided, that clause (iv) will not be deemed to have
been violated if in response to an unsolicited inquiry, the Selling Stockholder
states that it or he is subject to the provisions of the Stockholder Agreement.
 
     Each of the Selling Stockholders has also agreed until the Stockholder
Agreement has terminated, and the Stockholder Agreement includes an irrevocable
proxy provision for the benefit of the Purchaser with respect to the Shares
subject to the Stockholder Agreement owned by each Selling Stockholder, (i) to
vote such Shares at any meeting of stockholders of the Company called to vote
upon the Merger and the Merger Agreement or at any adjournment thereof or in any
other circumstances upon which a vote, consent or other approval (including by
written consent) with respect to the Merger and the Merger Agreement is sought,
in favor of the Merger, the adoption by the Company of the Merger Agreement and
the approval of the terms thereof and each of the other transactions
contemplated by the Merger Agreement; and (ii) to vote such Shares at any
meeting of stockholders of the Company or at any adjournment thereof or in any
other circumstances upon which a Selling Stockholder's vote, consent or other
approval is sought, against (x) any Takeover Proposal or (y) any amendment of
the Company's certificate of incorporation or by-laws or other proposal or
transaction involving the Company, which amendment or other proposal or
transaction would be reasonably likely to impede, frustrate, prevent or nullify
the Merger, the Merger Agreement or any of the other transactions contemplated
by the Merger Agreement or change in any manner the voting rights of each class
of the Company's common stock.
 
     The Stockholder Agreement provides that in the event that the Merger
Agreement shall have been terminated under circumstances where Parent is or may
become entitled to receive the Termination Fee, each Stockholder shall pay to
Parent on demand an amount equal to the difference between the consideration
received by such Stockholder from the consummation of any transaction which
gives rise to the Company's obligation to pay the Termination Fee pursuant to
the Merger Agreement and the consideration such Stockholder would have received
had he or it tendered his Shares pursuant to the Offer (without taking into
account any modifications to the Offer as in effect on the date hereof), as
determined in accordance with the Stockholder Agreement.
 
     In addition, in the event that (x) prior to the Effective Time, a Takeover
Proposal shall have been made and (y) the Effective Time shall have occurred and
Parent for any reason shall have increased the amount of Merger Consideration
payable over that set forth in the Merger Agreement in effect on the date
thereof (the "Original Merger Consideration"), each Selling Stockholder agrees
in the Stockholder Agreement to pay to Parent on demand an amount in cash equal
to the product of (i) the number of Shares of such Selling Stockholder subject
to the Stockholder Agreement and (ii) 100% of the excess, if any, of (A) the per
Share
 
                                       21
<PAGE>   24
 
cash consideration or the per Share fair market value of any noncash
consideration, as the case may be, received by such Selling Stockholder as a
result of the Merger, as amended, determined as of the Effective Time, over (B)
the amount of the Original Merger Consideration determined as of the time of the
first increase in the amount of the Original Merger Consideration.
 
     Appraisal Rights.  Holders of Shares do not have dissenters' rights as a
result of the Offer. However, if the Merger is consummated, holders of Shares
will have certain rights pursuant to the provisions of Section 262 of the DGCL
to dissent and demand appraisal of, and to receive payment in cash of the fair
value of, their Shares. If the statutory procedures were complied with, such
rights could lead to a judicial determination of the fair value required to be
paid in cash to such dissenting holders for their Shares. Any such judicial
determination of the fair value of Shares could be based upon considerations
other than or in addition to the Offer Price or the market value of the Shares,
including asset values and the investment value of the Shares. The value so
determined could be more or less than the Offer Price or the Merger
Consideration.
 
     If any stockholder of Shares who demands appraisal under Section 262 of the
DGCL fails to perfect, or effectively withdraws or loses his right to appraisal,
as provided in the DGCL, the Shares of such stockholder will be converted into
the Merger Consideration in accordance with the Merger Agreement. A stockholder
may withdraw his demand for appraisal by delivery to Parent of a written
withdrawal of his demand for appraisal and acceptance of the Merger.
 
     The foregoing discussion is not a complete statement of law pertaining to
appraisal rights under the DGCL and is qualified in its entirety by the full
text of Section 262 of the DGCL.
 
     FAILURE TO FOLLOW THE STEPS REQUIRED BY SECTION 262 OF THE DGCL FOR
PERFECTING APPRAISAL RIGHTS MAY RESULT IN THE LOSS OF SUCH RIGHTS.
 
     Going Private Transactions.  The Merger would have to comply with any
applicable Federal law operative at the time of its consummation. Rule 13e-3
under the Exchange Act is applicable to certain "going private" transactions.
The Purchaser does not believe that Rule 13e-3 will be applicable to the Merger
unless the Merger is consummated more than one year after the termination of the
Offer. If applicable, Rule 13e-3 would require, among other things, that certain
financial information concerning the Company and certain information relating to
the fairness of the Merger and the consideration offered to minority
shareholders be filed with the Commission and disclosed to minority shareholders
prior to consummation of the Merger.
 
     Other Matters.  Except as otherwise described in this Offer to Purchase,
the Purchaser and Parent have no current plans or proposals that would relate
to, or result in, any extraordinary corporate transaction involving the Company,
such as a merger, reorganization or liquidation involving the Company, a sale or
transfer of a material amount of assets of the Company, any change in the
Company's capitalization or dividend policy or any other material change in the
Company's business, corporate structure or personnel.
 
13.  DIVIDENDS AND DISTRIBUTIONS
 
     Pursuant to the terms of the Merger Agreement, the Company is prohibited
from taking any of the actions described in the succeeding paragraph, and
nothing herein shall constitute a waiver by the Purchaser or Parent of any of
its rights under the Merger Agreement or a limitation of remedies available to
the Purchaser or Parent for any breach of the Merger Agreement, including
termination thereof.
 
     If, on or after the date of the Merger Agreement, the Company should (a)
split, combine or otherwise change the Shares or its capitalization, (b) acquire
currently outstanding Shares or otherwise cause a reduction in the number of
outstanding Shares or (c) issue or sell 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, other than Shares issued pursuant to the exercise of
outstanding employee stock options, then, subject to the provisions of Section
14 below, the 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.
 
                                       22
<PAGE>   25
 
     If, on or after the date of the Merger Agreement, the Company should
declare or pay any cash dividend on the Shares or other distribution on the
Shares, or issue with respect to the Shares 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 the 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 14 below, (a) the
Offer Price may, in the sole discretion of the 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 issuance to be received by the tendering
stockholders will (i) be received and held by the tendering stockholders for the
account of the Purchaser and will be required to be promptly remitted and
transferred by each tendering stockholder to the Depositary for the account of
the Purchaser, accompanied by appropriate documentation of transfer, or (ii) at
the direction of the Purchaser, be exercised for the benefit of the Purchaser,
in which case the proceeds of such exercise will promptly be remitted to the
Purchaser. Pending such remittance and subject to applicable law, the Purchaser
will be entitled to all rights and privileges as owner of any such 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 the Purchaser in its sole discretion.
 
14.  CERTAIN CONDITIONS OF THE OFFER
 
     Notwithstanding any other term of the Offer, the Purchaser shall not be
required to accept for payment or, subject to any applicable rules and
regulations of the Commission, including Rule 14e-1(c) under the Exchange Act
(relating to the Purchaser's obligation to pay for or return tendered Shares
after the termination or withdrawal of the Offer), to pay for any Shares
tendered pursuant to the Offer unless (i) the Minimum Condition shall have been
satisfied and (ii) any waiting period under the HSR Act applicable to the
purchase of Shares pursuant to the Offer shall have expired or been terminated.
Furthermore, notwithstanding any other term of the Offer, the Purchaser shall
not be required to accept for payment or, subject as aforesaid, to pay for any
Shares not theretofore accepted for payment or paid for, and may terminate the
Offer if, at any time on or after the date of the Merger Agreement and before
the acceptance of such Shares for payment or the payment therefor, any of the
following conditions exists (other than as a result of any action or inaction of
Parent or any of its subsidiaries that constitutes a breach of the Merger
Agreement):
 
          (a) there shall be instituted or pending by any person or Governmental
     Entity any suit, action or proceeding (i) challenging the acquisition by
     Parent or the Purchaser of any Shares under the Offer or pursuant to the
     Stockholder Agreement, seeking to restrain or prohibit the making or
     consummation of the Offer or the Merger or the performance of any of the
     other transactions contemplated by the Merger Agreement or the Stockholder
     Agreement (including the voting provision thereunder), or seeking to obtain
     from the Company, Parent or the Purchaser any damages in connection with
     the aforesaid transactions that are material in relation to the Company,
     (ii) seeking to prohibit or materially limit the ownership or operation by
     the Company, Parent or any of their respective subsidiaries of a material
     portion of the business or assets of the Company or Parent and its
     subsidiaries, taken as a whole, or to compel the Company or Parent to
     dispose of or hold separate any material portion of the business or assets
     of the Company, or Parent and its subsidiaries, taken as a whole, as a
     result of the Offer or any of the other transactions contemplated by the
     Merger Agreement or the Stockholder Agreement, (iii) seeking to impose
     material limitations on the ability of Parent or the Purchaser to acquire
     or hold, or exercise full rights of ownership of, any Shares to be accepted
     for payment pursuant to the Offer or purchased under the Stockholder
     Agreement including, without limitation, the right to vote such Shares on
     all matters properly presented to the stockholders of the Company, (iv)
     seeking to prohibit Parent or any of its subsidiaries from effectively
     controlling in any material respect any material portion of the business or
     operations of the Company or (v) which otherwise is reasonably likely to
     have a material adverse effect on the Company;
 
          (b) there shall be any statute, rule, regulation, judgment, order or
     injunction enacted, entered, enforced, promulgated or deemed applicable to
     the Offer or the Merger, or any other action shall be taken by any
 
                                       23
<PAGE>   26
 
     Governmental Entity or court, other than the application to the Offer or
     the Merger of applicable waiting periods under the HSR Act, that is
     reasonably likely to result, directly or indirectly, in any of the
     consequences referred to in clauses (i) through (v) of paragraph (a) above;
     provided, however, that each of Parent and the Purchaser shall have used
     reasonable efforts to prevent the entry of any such injunction or other
     court order and to appeal as promptly as possible any injunction or other
     court order that may be entered;
 
          (c) there shall have occurred any material adverse change with respect
     to the Company;
 
          (d) any of the representations and warranties of the Company set forth
     in the Merger Agreement (without giving effect to any materiality or
     similar qualifications contained therein) shall not be true and correct at
     the date of the Merger Agreement and at the scheduled or extended
     expiration of the Offer except (i) for changes specifically permitted by
     the Merger Agreement and (ii) in any case where such failing to be true and
     correct could not, in the aggregate, be reasonably expected to have a
     material adverse effect on the Company;
 
          (e) the Company shall have failed to perform in any material respect
     any material obligation or to comply in any material respect with any
     material agreement or covenant of the Company to be performed or complied
     with by it under the Merger Agreement; or
 
          (f) the Merger Agreement shall have been terminated in accordance with
     its terms;
 
which, in the judgment of the Purchaser in any such case, and regardless of the
circumstances (including any action or omission by the Purchaser) giving rise to
any such condition, makes it inadvisable to proceed with such acceptance for
payment or payments.
 
     The Merger Agreement provides that the foregoing conditions in paragraphs
(a) through (f) are for the sole benefit of the Purchaser and Parent and may,
subject to the terms of the Merger Agreement, be waived by the Purchaser and
Parent in whole or in part at any time and from time to time in their sole
discretion. The failure by Parent or the Purchaser at any time to exercise any
of the foregoing rights shall not be deemed a waiver of any such right, the
waiver of any such right with respect to particular facts and circumstances
shall not be deemed a waiver with respect to any other facts and circumstances
and each such right shall be deemed an ongoing right that may be asserted at any
time and from time to time.
 
15.  CERTAIN LEGAL MATTERS
 
     Based on a review of publicly available filings made by the Company with
the Commission and other publicly available information concerning the Company,
neither the 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 Purchaser's
acquisition of Shares as contemplated herein or of any approval or other action,
except as otherwise described in this Section 15, by any Governmental Entity
that would be required for the acquisition or ownership of Shares by the
Purchaser as contemplated herein. Should any such approval or other action be
required, the Purchaser and Parent currently contemplate that such approval or
other action will be sought, except as described below under "State Takeover
Laws". While, except as otherwise expressly described in this Section 15, the
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 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 if 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, the Purchaser could, subject to the
terms and conditions of the Merger Agreement, decline to accept for payment or
pay for any Shares tendered. See Section 14 for certain conditions to the Offer.
 
     State Takeover Laws.  A number of states throughout the United States have
enacted takeover statutes that purport, in varying degrees, to be applicable to
attempts to acquire securities of corporations that are
 
                                       24
<PAGE>   27
 
incorporated or have assets, stockholders, executive offices or places or
business in such states. In Edgar v. MITE Corp., the Supreme Court of the United
States held that the Illinois Business Takeover Act, which involved state
securities laws that made the takeover of certain corporations more difficult,
imposed a substantial burden on interstate commerce and therefore was
unconstitutional. In CTS Corp. v. Dynamics Corp. of America, however, the
Supreme Court of the United States held that a state may, as a matter of
corporate law, and, in particular, those laws concerning corporate governance,
constitutionally disqualify a potential acquiror from voting on the affairs of a
target corporation without prior approval of the remaining stockholders;
provided that such laws were applicable only under certain conditions.
Subsequently, a number of Federal courts ruled that various state takeover
statutes were unconstitutional insofar as they apply to corporations
incorporated outside the state of enactment.
 
     Section 203 of the DGCL limits the ability of a Delaware corporation to
engage in business combinations with "interested stockholders" (defined
generally as any beneficial owner of 15% or more of the outstanding voting stock
of the corporation) for a period of three years from the time such interested
stockholders became the holders of 15% or more of such Shares unless, among
other things, the corporation's board of directors has given its prior approval
to either the business combination or the transaction which resulted in the
stockholder becoming an "interested stockholder". The Company's Board of
Directors has approved the Merger Agreement, the Stockholder Agreement and the
Purchaser's acquisition of Shares pursuant to the Offer and, therefore, Section
203 of DGCL is inapplicable to the Merger.
 
     Based on information supplied by the Company and its own review, the
Purchaser does not believe that any state takeover statutes purport to apply to
the Offer or the Merger. Neither the Purchaser nor Parent has currently complied
with any state takeover statute or regulation. The Purchaser reserves the right
to challenge the applicability or validity of any state law purportedly
applicable to the Offer or the Merger and nothing in this Offer to Purchase or
any action taken in connection with the Offer or the Merger is intended as a
waiver of such right. If it is asserted that any state takeover statute is
applicable to the Offer or the Merger and an appropriate court does not
determine that it is inapplicable or invalid as applied to the Offer or the
Merger, the Purchaser might be required to file certain information with, or to
receive approvals from, the relevant state authorities, and the Purchaser might
be unable to accept for payment or pay for Shares tendered pursuant to the
Offer, or be delayed in consummating the Offer or the Merger. In such case, the
Purchaser may not be obliged to accept payment or pay for any Shares tendered
pursuant to the Offer.
 
     Antitrust.  Under the provisions of the HSR Act applicable to the Offer,
the purchase of Shares under the Offer may be consummated following the
expiration of a 15-calendar day waiting period following the filing by Parent of
a Notification and Report Form with respect to the Offer, unless Parent receives
a request for additional information or documentary material from the Antitrust
Division or the FTC or unless early termination of the waiting period is
granted. Parent is in the process of making such filing. If, within the initial
15-day waiting period, either the Antitrust Division or the FTC requests
additional information or material from Parent concerning the Offer, the waiting
period will be extended and would expire at 11:59 p.m., New York City time, on
the tenth calendar day after the date of 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 provisions of the HSR Act would similarly apply to any purchase of the
Shares subject to the Stockholder Agreement pursuant to the Stockholder
Agreement (other than purchases effected through a tender pursuant to the
Offer), except that the initial waiting period would expire 30 days following
the filing of HSR Act Notification Forms by Parent and the Company and a request
for additional information or material from Parent or the Company during the
initial 30-day waiting period would extend the waiting period until 11:59 p.m.,
New York City time, on the 20th day after the date of substantial compliance by
Parent and the Company with such request. Parent and the Company are in the
process of filing HSR Notification Forms
 
                                       25
<PAGE>   28
 
with respect to the Stockholder Agreement. If, as is expected, the purchase of
Shares permitted by the Stockholder Agreement is effected through a tender of
such Shares pursuant to the Offer, the HSR requirements applicable to the Offer
described in the prior paragraph would apply rather than the requirements
described in this paragraph.
 
     The Merger would not require an additional filing under the HSR Act if the
Purchaser owns 50% or more of the outstanding Shares at the time of the Merger
or if the Merger occurs within one year after the HSR Act waiting period
applicable to the Offer expires or is terminated.
 
     The FTC and the Antitrust Division frequently scrutinize the legality under
the antitrust laws of transactions such as the Purchaser's proposed acquisition
of the Company. At any time before or after the Purchaser's purchase of Shares
pursuant to the Offer, the Antitrust Division or FTC could take such action
under the antitrust laws as it deems necessary or desirable in the public
interest, including seeking to enjoin the purchase of Shares pursuant to the
Offer or the consummation of the Merger or seeking the divestiture of Shares
acquired by the Purchaser or the divestiture of substantial assets of Parent or
its subsidiaries, or the Company or its subsidiaries. Private parties may also
bring legal action under the antitrust laws under certain circumstances. There
can be no assurance that a challenge to the Offer on antitrust grounds will not
be made or, if such a challenge is made, of the results thereof.
 
16.  FEES AND EXPENSES
 
     The Purchaser has retained Georgeson & Company Inc. to act as the
Information Agent and First Chicago Trust Company of New York to serve as the
Depositary in connection with the Offer. The Information Agent and the
Depositary each will 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 therewith,
including certain liabilities under the Federal securities laws.
 
     Neither the Purchaser nor Parent will pay any fees or commissions to any
broker or dealer or other person (other than the Information Agent) in
connection with the solicitation of tenders of Shares pursuant to the Offer.
Brokers, dealers, banks and trust companies will be reimbursed by the Purchaser
upon request for customary mailing and handling expenses incurred by them in
forwarding material to their customers.
 
17.  MISCELLANEOUS
 
     The Offer is not being made to (nor will tenders be accepted from or on
behalf of) holders of Shares in any jurisdiction in which the making of the
Offer or the acceptance thereof would not be in compliance with the laws of such
jurisdiction. Neither of the Purchaser or Parent is aware of any jurisdiction in
which the making of the Offer or the tender of Shares in connection therewith
would not be in compliance with the laws of such jurisdiction. To the extent the
Purchaser or Parent becomes aware of any state law that would limit the class of
offerees in the Offer, the Purchaser will amend the Offer and, depending on the
timing of such amendment, if any, will extend the Offer to provide adequate
dissemination of such information to holders of Shares prior to the expiration
of the Offer. In any jurisdiction the securities, blue sky or other laws of
which require the Offer to be made by a licensed broker or dealer, the Offer is
being made on behalf of the Purchaser by the Information Agent or one or more
registered brokers or dealers licensed under the laws of such jurisdiction.
 
     NO PERSON HAS BEEN AUTHORIZED TO GIVE ANY INFORMATION OR TO MAKE ANY
REPRESENTATION ON BEHALF OF THE PURCHASER OR PARENT NOT CONTAINED HEREIN OR IN
THE LETTER OF TRANSMITTAL AND, IF GIVEN OR MADE, SUCH INFORMATION OR
REPRESENTATION MUST NOT BE RELIED UPON AS HAVING BEEN AUTHORIZED.

                                  INSTRUCTIONS
 
             FORMING PART OF THE TERMS AND CONDITIONS OF THE OFFER
 
     1. Guarantee of Signature.  Except as otherwise provided below, all
signatures on this Letter of Transmittal must be guaranteed by a financial
institution (including most banks, savings and loans associations and brokerage
houses) that is a participant in the Security Transfer Agents Medallion Program
or the New York Stock Exchange Medallion Signature Guarantee Program or the
Stock Exchange Medallion Program (an "Eligible Institution"). No signature
guarantee is required on this Letter of Transmittal (a) if this Letter of
Transmittal is signed by the registered holder(s) (which term, for purposes of
this document, shall include any participant in a Book-Entry Transfer Facility
whose name appears on a security position listing as the owner of the Shares) of
Shares tendered herewith, unless such holder(s) has completed either the box
entitled "Special Payment Instructions" or the box entitled "Special Delivery
Instructions" on the reverse hereof, or (b) if such Shares are tendered for the
account of an Eligible Institution. See Instruction 5.
 
     2. Requirements of Tender.  This Letter of Transmittal is to be completed
by stockholders either if certificates are to be forwarded herewith or if
delivery of Shares is to be made pursuant to the procedures for book-entry
transfer set forth in Section 2 of the Offer to Purchase. For a stockholder
validly to tender Shares pursuant to the Offer, either (a) a properly completed
and duly executed Letter of Transmittal (or facsimile thereof), together with
any required signature guarantees 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 delivered pursuant to the procedures for book-entry transfer set
forth herein 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 below and in Section 2 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 or complete the procedures for book-entry transfer prior to the
Expiration Date may tender their Shares by properly completing and duly
executing the Notice of Guaranteed Delivery pursuant to the guaranteed delivery
procedures set forth in Section 2 of the Offer to Purchase.
 
     Pursuant to such procedures, (a) such tender must be made by or through an
Eligible Institution, (b) a properly completed and duly executed Notice of
Guaranteed Delivery substantially in the form provided by the Purchaser must be
received by the Depositary prior to the Expiration Date and (c) the certificates
for all physically delivered Shares or a Book-Entry Confirmation with respect to
all tendered Shares, as well as a properly completed and duly executed Letter of
Transmittal (or facsimile thereof) with any required signature guarantees and
any other documents required by this Letter of Transmittal, must be received by
the Depositary within five New York Stock Exchange, Inc. trading days after the
date of execution of the Notice of Guaranteed Delivery.
 
     THE METHOD OF DELIVERY OF SHARES, THE LETTER OF TRANSMITTAL AND ALL OTHER
REQUIRED DOCUMENTS IS AT THE ELECTION AND RISK OF THE TENDERING STOCKHOLDER. IF
DELIVERY IS BY MAIL, REGISTERED MAIL WITH RETURN RECEIPT REQUESTED, PROPERLY
INSURED, IS RECOMMENDED. IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO
ENSURE TIMELY DELIVERY.
 
     No alternative, conditional or contingent tenders will be accepted and no
fractional Shares will be purchased. All tendering stockholders, by execution of
this Letter of Transmittal (or facsimile thereof), waive any right to receive
any notice of the acceptance of their Shares for payment.
 
     3. Inadequate Space.  If the space provided herein is inadequate, the
certificate numbers and/or the number of Shares should be listed on a separate
schedule attached hereto.
 
     4. Partial Tenders (Applicable to Certificate Stockholders Only).  If fewer
than all the Shares evidenced by any certificate submitted are to be tendered,
fill in the number of Shares 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 certificate(s) 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 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 of the Shares
tendered hereby, the signature must correspond with the name as written on the
face of the certificate(s) without any change whatsoever.
 
     If any of the Shares tendered hereby are owned of record by two or more
joint owners, all such owners must sign this Letter of Transmittal.
 
     If any tendered Shares are registered in different names on several
certificates, it will be necessary to complete, sign and submit as many separate
Letters of Transmittal as there are different registrations of certificates.
 
     If this Letter of Transmittal or any certificates or stock powers are
signed by trustees, executors, administrators, guardians, attorneys-in-fact,
officers of corporations or others acting in a fiduciary or representative
capacity, such persons should so indicate when signing, and proper evidence
satisfactory to the Purchaser of their authority so to act must be submitted.
<PAGE>   8
 
     When this Letter of Transmittal is signed by the registered holder(s) of
the Shares listed and transmitted hereby, no endorsements of certificates or
separate stock powers are required unless payment is to be made to, or
certificates for Shares not tendered or accepted for payment are to be issued
to, a person other than the registered owner(s). Signatures on such certificates
or stock powers must be guaranteed by an Eligible Institution.
 
     If this Letter of Transmittal is signed by a person other than the
registered holder(s) of the certificates listed, the certificates must be
endorsed or accompanied by appropriate stock powers, in either case signed
exactly as the name or names of the registered owner or owners appear on the
certificates. Signatures on such certificates or stock powers must be guaranteed
by an Eligible Institution.
 
     6. Stock Transfer Taxes.  The Purchaser will pay any stock transfer taxes
with respect to the transfer and sale of Shares to it or its order pursuant to
the Offer. If, however, payment of the purchase price is to be made to, or if
certificates for Shares not tendered or accepted for payment are to be
registered in the name of, any person(s) other than the registered owner(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 person) payable on
account of the transfer to such person will be deducted from the purchase price
unless satisfactory evidence of the payment of such taxes or exemption therefrom
is submitted.
 
     EXCEPT AS PROVIDED IN THIS INSTRUCTION 6, IT WILL NOT BE NECESSARY FOR
TRANSFER TAX STAMPS TO BE AFFIXED TO THE CERTIFICATES LISTED IN THIS LETTER OF
TRANSMITTAL.
 
     7. Special Payment and Delivery Instructions.  If a check is to be issued
in the name of and/or certificates for Shares not tendered or not accepted for
payment are to be returned to, a person other than the signer of this Letter of
Transmittal or if a check is to be sent and/or such 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 must be completed. Any stockholder(s) delivering Shares by
book-entry transfer may request that Shares not accepted for payment be credited
to such account maintained at a Book-Entry Transfer Facility as such
stockholder(s) may designate.
 
     8. Waiver of Conditions.  Subject to the terms of the Offer, the Purchaser
reserves the absolute right in its sole discretion to waive any of the specified
conditions of the Offer, in whole or in part, in the case of any Shares
tendered.
 
     9. 31% Backup Withholding.  Under U.S. Federal income tax law, a
stockholder whose tendered Shares are accepted for payment is required to
provide the Depositary with such stockholder's correct taxpayer identification
number ("TIN") on Substitute Form W-9 below. If the Depositary is not provided
with the correct TIN or an adequate basis for exemption, the Internal Revenue
Service may subject the stockholder or other payee to a $50 penalty. In
addition, payments that are made to such stockholder or other payee with respect
to Shares purchased pursuant to the Offer may be subject to a 31% backup
withholding.
 
     Certain stockholders (including, among others, all corporations and certain
foreign individuals) are not subject to these backup withholding and reporting
requirements. In order for a foreign individual to qualify as an exempt
recipient, the stockholder must submit a Form W-8, signed under penalties of
perjury, attesting to that individual's exempt status. A Form W-8 can be
obtained from the Depositary. See the enclosed "Guidelines for Certification of
Taxpayer Identification Number on Substitute Form W-9" for more instructions.
 
     If backup withholding applies, the Depositary is required to withhold 31%
of any such payments made to the stockholder or other payee. Backup withholding
is not an additional income tax. Rather, the tax liability of persons subject to
backup withholding will be reduced by the amount of tax withheld, provided that
the required information is given to the Internal Revenue Service. If
withholding results in an overpayment of taxes, a refund may be obtained from
the Internal Revenue Service.
 
     The box in Part 3 of the Substitute Form W-9 may be checked if the
tendering stockholder has not been issued a TIN and has applied for a TIN or
intends to apply for a TIN in the near future. If the box in Part 3 is checked,
the stockholder or other payee must also complete the Certificate of Awaiting
Taxpayer Identification Number below in order to avoid backup withholding.
Notwithstanding that the box in Part 3 is checked and the Certificate of
Awaiting Taxpayer Identification Number is completed, the Depositary will
withhold 31% 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.
 
     The stockholder is required to give Depositary the TIN (e.g., social
security number or employer identification number) of the record owner of the
Shares or of the last transferee appearing on the transfers attached to, or
endorsed on, the Shares. If the Shares are in more than one name or are not in
the name of the actual owner, consult the enclosed "Guidelines for Certification
of Taxpayer Identification Number on Substitute Form W-9" for additional
guidance on which number to report.
 
     10. Requests for Assistance or Additional Copies.  Requests for additional
copies of the Offer to Purchase, this Letter of Transmittal, the Notice of
Guaranteed Delivery and the Guidelines for Certification of Taxpayer
Identification Number on Substitute Form W-9 should be directed to the
Information Agent at its addresses set forth below. Questions or requests for
assistance may be directed to the Information Agent.
 
     IMPORTANT: THIS LETTER OF TRANSMITTAL OR A FACSIMILE THEREOF (TOGETHER WITH
CERTIFICATES FOR, OR A BOOK-ENTRY CONFIRMATION WITH RESPECT TO, TENDERED SHARES
WITH ANY REQUIRED SIGNATURE GUARANTEES AND ALL OTHER REQUIRED DOCUMENTS) MUST BE
RECEIVED BY THE DEPOSITARY, OR THE NOTICE OF GUARANTEED DELIVERY MUST BE
RECEIVED BY THE DEPOSITARY, PRIOR TO THE EXPIRATION DATE.

     The Offer is conditioned upon, among other things, there being validly
tendered and not withdrawn prior to the expiration of the Offer that number of
Shares which, together with the Shares subject to the Stockholder Agreement
referred to in the Offer to Purchase that shall not have been so tendered, would
represent at least a majority of all Shares determined on a fully diluted basis.
 
     The Board of Directors of the Company has, by unanimous vote, approved the
Offer and the Merger (as defined below) and determined that the terms of the
Offer and the Merger are fair to, and in the best interests of, the stockholders
of the Company and recommends that stockholders of the Company accept the Offer
and tender their Shares.

with and into the Company, with the Company surviving the merger as a wholly
owned subsidiary of Parent (the "Merger"). In the Merger, each outstanding Share
(other than Shares owned by the Company as treasury stock or by Parent, the
Purchaser or any other subsidiary of Parent or by stockholders, if any, who are
entitled to and who properly exercise dissenters' rights under Delaware law)
will be converted into the right to receive $13.75 per Share, without interest,
as set forth in the Merger Agreement and described in the Offer to Purchase.
 
     In all cases, payment for Shares accepted for payment pursuant to the Offer
will be made only after timely receipt by the Depositary of certificates for
such Shares (or timely Book-Entry Confirmation of a transfer of such Shares as
described in Section 2 of the Offer to Purchase), a properly completed and duly
executed Letter of Transmittal (or facsimile thereof) and any other documents
required by the Letter of Transmittal.
 
     Neither the Purchaser nor Parent will pay any fees or commissions to any
broker or dealer or other person (other than the Information Agent as described

Shares pursuant to the Offer. You will be reimbursed upon request for customary
mailing and handling expenses incurred by you in forwarding the enclosed

                               JOHNSON & JOHNSON
 
     INO Acquisition Corp., a Delaware corporation (the "Purchaser") and a
wholly owned subsidiary of Johnson & Johnson, a New Jersey corporation
("Parent"), is offering to purchase all outstanding shares of Common Stock, par
value $.001 per share (the "Shares"), of Innotech, Inc., a Delaware corporation
(the "Company"), at $13.75 per Share, net to the seller in cash, upon the terms
and subject to the conditions set forth in the Offer to Purchase dated February
18, 1997 and in the related Letter of Transmittal (which together constitute the
"Offer").
 
         THE OFFER AND WITHDRAWAL RIGHTS WILL EXPIRE AT 12:00 MIDNIGHT,
        NEW YORK CITY TIME, ON MONDAY, MARCH 17, 1997, UNLESS EXTENDED.
 
     The Offer is conditioned upon, among other things, there being validly
tendered and not withdrawn prior to Monday, March 17, 1997 (x) that number of
Shares which, together with the Shares subject to the Stockholder Agreement (as
defined below) that shall not have been so tendered, would represent at least a
majority of all outstanding Shares (for purposes of this clause (x) only,
"Shares" shall be deemed to refer only to Shares outstanding as of the date of
the Merger Agreement (as defined below)) and (y) that number of Shares which,
together with the Shares subject to the Stockholder Agreement that shall not
have been so tendered, would represent at least a majority of the fully diluted
Shares as of the date of determination (determined on a fully diluted basis for
all outstanding stock options and any other rights to acquire Shares) (the
conditions in (x) and (y) collectively, the "Minimum Condition").
 
     The Offer is being made pursuant to an Agreement and Plan of Merger dated
as of February 10, 1997 (the "Merger Agreement"), among Parent, the Purchaser
and the Company pursuant to which, following the consummation of the Offer, the
Purchaser will be merged with and into the Company (the "Merger"). On the
effective date of the Merger, each outstanding Share (other than Shares owned by
Parent, the Purchaser or any other subsidiary of Parent or by stockholders, if
any, who are entitled to and who properly exercise
<PAGE>   2
 
dissenters' rights under Delaware law) will be converted into the right to
receive $13.75 in cash, without interest.
 
     The Board of Directors of the Company has approved the Offer and the Merger
and determined that the terms of the Offer and the Merger are fair to, and in
the best interests of, the stockholders of the Company, and recommends that
stockholders of the Company accept the Offer and tender their Shares.
 
     The Purchaser and Parent have also entered into a Stockholder Agreement
dated as of February 10, 1997 (the "Stockholder Agreement") with certain
stockholders of the Company who beneficially own 3,331,608 outstanding Shares in
the aggregate. Under the Stockholder Agreement, those stockholders have agreed
to sell all such Shares to the Purchaser for $13.75 per Share in cash if the
Minimum Condition is satisfied and the Purchaser shall have accepted Shares for
payment under the Offer. Such stockholders may, and at the request of the
Purchaser shall, tender their Shares into the Offer. In addition, such
stockholders have agreed to vote their Shares in favor of the Merger, the
adoption by the Company of the Merger Agreement and the approval of the terms
thereof and each of the other transactions contemplated by the Merger Agreement,
and have agreed to vote against any transactions pertaining to such Shares with
any person other than pursuant to the terms of the Merger.
 
     For purposes of the Offer, the Purchaser shall be deemed to have accepted
for payment, and thereby purchased, Shares properly tendered to the Purchaser
and not withdrawn as, if and when the Purchaser gives oral or written notice to
the Depositary of the Purchaser's acceptance for payment of such Shares. Upon
the terms and subject to the conditions of the Offer, payment for Shares
purchased pursuant to the Offer will be made by deposit of the purchase price
therefor with the Depositary, which will act as agent for tendering stockholders
for the purpose of receiving payment from the Purchaser and transmitting payment
to tendering stockholders. In all cases, payment for Shares purchased pursuant
to the Offer will be made only after timely receipt by the Depositary of (a)
certificates for such Shares or timely confirmation of book-entry transfer of
such Shares into the Depositary's account at a Book-Entry Transfer Facility (as
defined in the Offer to Purchase) pursuant to the procedures set forth in
Section 2 of the Offer to Purchase, (b) a properly completed and duly executed
Letter of Transmittal (or facsimile thereof) with any required signature
guarantees and (c) any other documents required by the Letter of Transmittal.
Under no circumstances will interest be paid by the Purchaser on the purchase
price of the Shares, regardless of any delay in making such payment.
 
     The term "Expiration Date" means 12:00 Midnight, New York City time, on
Monday, March 17, 1997 unless and until the Purchaser, in its sole discretion
but subject to the terms of the Merger Agreement, shall have extended the period
of time during which the Offer is open, in which event the term "Expiration
Date" shall mean the latest time and date on which the Offer, as so extended by
the Purchaser, shall expire. The Purchaser expressly reserves the right, in its
sole discretion (but subject to the terms of the Merger Agreement), at any time
or from time to time, and regardless of whether or not any of the events set
forth in Section 14 of the Offer to Purchase shall have occurred, to extend the
period of time during which the Offer is open and thereby delay acceptance for
payment of, and the payment for, any Shares, by giving oral or written notice of
such extension to the Depositary. The Purchaser shall not have any obligation to
pay interest on the purchase price for tendered Shares in the event the
Purchaser exercises its right to extend the period of time during which the
Offer is open. There can be no assurance that the Purchaser will exercise its
right to extend the Offer (other than as required by applicable law). Any
such extension will be followed by a public announcement thereof no later than
9:00 a.m., New York City time, on the next business day after the previously
scheduled Expiration Date. During any such extension, all Shares previously
tendered and not withdrawn will remain subject to the Offer, subject to the
right of a tendering stockholder to withdraw such stockholder's Shares.
 
     Except as otherwise provided below, tenders of Shares are irrevocable.
Shares tendered pursuant to the Offer may be withdrawn at any time prior to
12:00 Midnight, New York City time, on Monday, March 17, 1997, or, if the
Purchaser shall have extended the period of time during which the Offer is open,
the latest time and date at which the Offer, as so extended by the Purchaser,
shall expire and, unless theretofore accepted for payment, may also be withdrawn
at any time after April 17, 1997. 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

                             FOR IMMEDIATE RELEASE
 
    JOHNSON & JOHNSON TO ACQUIRE INNOTECH, INC. FOR $13.75 PER SHARE IN CASH
 
     New Brunswick, NJ (February 11, 1997) -- Johnson & Johnson (NYSE: JNJ) and
Innotech, Inc. (Nasdaq: IIII) today jointly announced that they have entered
into a definitive agreement whereby Innotech, Inc. will be acquired by Johnson &
Johnson for $13.75 per share in cash.
 
     Innotech, Inc. is a Roanoke, VA-based company which develops, manufactures
and sells lens products, desktop lens casting systems and related consumables
that enable eye care professionals and optical retailers to custom fabricate
high quality prescription eyeglass lenses at the point of sale.
 
     Under the terms of the agreement, Johnson & Johnson is to begin a cash
tender offer for all outstanding shares of Innotech, Inc. for $13.75 per share.
Any shares not purchased in the offer will be acquired for the same price in
cash, in a second-step merger. Innotech has approximately 9 million shares
outstanding. The boards of directors of both companies have given approval to
the acquisition.
 
     "This acquisition represents an important step in the growth of our vision
care franchise," said Ralph S. Larsen, Chairman and Chief Executive Officer of
Johnson & Johnson. "The Excalibur SurfaceCasting System possesses unique
technological advantages and has the potential to change the multifocal
spectacle lens industry." Johnson & Johnson was the pioneer in the establishment
of disposable contact lenses and is the worldwide leader in that market with its
ACUVUE, 1-Day ACUVUE and SUREVUE brands.
 
     Dr. Ronald D. Blum, O.D., Chairman and Chief Executive Officer of Innotech
commented: "We are extremely pleased to join forces with the global leader in
health care. Johnson & Johnson's established presence in the worldwide vision
care market, combined with Innotech's unique SurfaceCasting technology, provides
a strong platform for future growth."
 
     Steve Bennington, Innotech's president and chief operating officer, stated:
"The resources that Johnson & Johnson brings to bear, including but not limited
to financial, manufacturing and operational, as well as the high credibility
associated with the Johnson & Johnson name, will greatly assist Innotech in
penetrating the global market for our products.
 
     The offer and merger are subject to the purchase of a majority of the
outstanding shares of Innotech common stock, as well as other customary
conditions including clearance under the Hart-Scott-Rodino Anti-Trust
Improvements Act. The offer will begin within 5 business days and remain open
for a minimum of 20 business days. A shareholder group consisting of Chase
Venture Capital Associates, L.P., CIBC Wood Gundy Ventures, Inc. and Dr. Ronald
D. Blum, O.D., holders collectively of approximately 3.3 million shares
outstanding have agreed to tender all of their shares in the offer. Innotech
options and warrants to purchase approximately 850,000 shares will be cashed out
in connection with the merger.
 
     Prudential Securities Incorporated has provided financial advisory services
to Innotech's board of directors and has issued a fairness opinion on this
transaction. In the event that an unsolicited, alternative transaction is agreed
to by Innotech, there would be a total fee payable to Johnson & Johnson of $6.75
million.
 
     Innotech, Inc. was founded in 1990 and completed a $30 million Initial
Public Offering (IPO) in March 1996. For the nine months ended September 30,
1996, the company reported sales of $7.4 million and a net loss of $8.1 million
or $1.15 per share.

                           AGREEMENT AND PLAN OF MERGER dated as of February 10,
                  1997, among JOHNSON & JOHNSON, a New Jersey corporation
                  ("Parent"), INO ACQUISITION CORP., a Delaware corporation and
                  a wholly owned subsidiary of Parent ("Sub"), and INNOTECH,
                  INC., a Delaware corporation (the "Company").


         WHEREAS the respective Boards of Directors of Parent, Sub and the
Company have approved the acquisition of the Company by Parent on the terms and
subject to the conditions set forth in this Agreement;

         WHEREAS, in furtherance of such acquisition, Parent proposes to cause
Sub to make a tender offer to purchase all the outstanding shares of Common
Stock, par value $0.001 per share, of the Company (the "Company Common Stock";
all the outstanding shares of Company Common Stock being hereinafter
collectively referred to as the "Shares") at a purchase price of $13.75 per
Share (the "Offer Price"), net to the seller in cash, without interest thereon,
upon the terms and subject to the conditions set forth in this Agreement (as it
may be amended from time to time as permitted under this Agreement, the
"Offer"); and the Board of Directors of the Company has adopted resolutions
approving the Offer and the Merger (as defined below), recommending that the
Company's stockholders accept the Offer and approving the acquisition of Shares
by Sub pursuant to the Offer and the Stockholder Agreement (as defined below);

         WHEREAS the respective Boards of Directors of Parent, Sub and the
Company have each approved the merger of Sub into the Company (the "Merger"),
upon the terms and subject to the conditions set forth in this Agreement,
whereby each Share, other than Shares owned directly or indirectly by Parent or
the Company and Dissenting Shares (as defined in Section 3.01(d)), will be
converted into the right to receive the price per share paid in the Offer;

         WHEREAS, concurrently with the execution of this Agreement and as an
inducement to Parent to enter into this Agreement, Parent, Sub and certain
stockholders of the Company are entering into a Stockholder Agreement (the
"Stockholder Agreement") pursuant to which such stockholders have, among other
things, agreed to sell all such stockholders' Shares to Sub at a cash price per
Share equal

                                                                               2


to the Offer Price, or such higher price per Share as may be offered by Sub in
the Offer, upon the terms and subject to the conditions set forth in the
Stockholder Agreement;

         WHEREAS, concurrently with the execution of this Agreement and as an
inducement to Parent to enter into this Agreement, Parent and certain
stockholders of the Company who are employed by the Company are entering into
Noncompetition Agreements (the "Noncompetition Agreements") pursuant to which
such stockholders have, among other things, agreed to not have any Relationship
(as defined in the Noncompetition Agreements) with certain third parties during
the Noncompetition Period (as defined in the Noncompetition Agreements); and

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


         NOW, THEREFORE, in consideration of the foregoing and the mutual
covenants and agreements herein contained, and intending to be legally bound
hereby, Parent, Sub and the Company hereby agree as follows:


                                    ARTICLE I

                                    The Offer

         SECTION 1.01. The Offer. (a) Provided that none of the conditions set
forth on Exhibit A hereto shall have occurred and be continuing, as promptly as
practicable but in no event later than five business days after the date of the
public announcement (on the date hereof or the following day) by Parent and the
Company of this Agreement, Sub shall, and Parent shall cause Sub to, commence
(within the meaning of Rule 14d-2 under the Exchange Act (as hereinafter
defined)) the Offer. The obligation of Sub to, and of Parent to cause Sub to,
commence the Offer, conduct and consummate the Offer and accept for payment, and
pay for, any Shares tendered and not withdrawn pursuant to the Offer shall be
subject only to the conditions set forth in Exhibit A (the "Offer Conditions")
(any of which (other than the condition as to HSR Act (as hereinafter defined)
compliance) may be waived in whole or in part by Sub in its


<PAGE>   8


                                                                               3


sole discretion, provided that, without the express written consent of the
Company, Sub may not waive the Minimum Condition (as defined in Exhibit A)). Sub
expressly reserves the right, subject to compliance with the Exchange Act, to
modify the terms of the Offer, except that, without the express written consent
of the Company, Sub shall not (i) reduce the number of Shares subject to the
Offer, (ii) reduce the Offer Price, (iii) add to or modify the Offer Conditions,
(iv) except as provided in the next sentence, extend the Offer, (v) change the
form of consideration payable in the Offer or (vi) amend or alter any other term
of the Offer in any manner adverse to the holders of the Shares. Notwithstanding
the foregoing, Sub may, without the consent of the Company, (A) extend the Offer
for a specified period, if at the scheduled or any extended expiration date of
the Offer any of the Offer Conditions shall not be satisfied or waived, until
such time as such conditions are satisfied or waived, but in no event to a date
more than 90 calendar days from the commencement of the Offer, (B) extend the
Offer for any period required by any rule, regulation, interpretation or
position of the Securities and Exchange Commission (the "SEC") or the staff
thereof applicable to the Offer, (C) extend the Offer pursuant to Section
9.01(d) and (D) extend the Offer for any reason on one or more occasions for an
aggregate period of not more than 5 business days beyond the latest expiration
date that would otherwise be permitted under clause (A), (B) or (C) of this
sentence; provided, however, that the aggregate period of all extensions under
clauses (A), (B), (C) and (D) may not extend the expiration date of the Offer to
a date more than 90 calendar days from the commencement of the Offer. Subject to
the terms and conditions of the Offer and this Section 1.01(a), Sub shall, and
Parent shall cause Sub to, accept for payment, and pay for, all Shares validly
tendered and not withdrawn pursuant to the Offer that Sub becomes obligated to
accept for payment, and pay for, pursuant to the Offer as soon as practicable
after the expiration of the Offer.

         (b) On the date of commencement of the Offer, Parent and Sub shall file
with the SEC a Tender Offer Statement on Schedule 14D-1 (the "Schedule 14D-1")
with respect to the Offer, which shall contain an offer to purchase and a
related letter of transmittal and summary advertisement (such Schedule 14D-1 and
the documents included therein pursuant to which the Offer will be made,
together with any supplements or amendments thereto, the "Offer Documents").
Parent and Sub agree that the Offer

                                                                               4


Documents shall comply as to form in all material respects with the Securities
Exchange Act of 1934, as amended (the "Exchange Act"), and the rules and
regulations promulgated thereunder, and the Offer Documents, on the date first
published, sent or given to the Company's stockholders, shall not contain any
untrue statement of a material fact or omit to state any material fact required
to be stated therein or necessary in order to make the statements therein, in
light of the circumstances under which they were made, not misleading, except
that no representation or warranty is made by Parent or Sub with respect to
written information supplied by the Company or any of its stockholders
specifically for inclusion or incorporation by reference in the Offer Documents.
Parent, Sub and the Company each agrees promptly to correct any written
information provided by it for use in the Offer Documents if and to the extent
that such information shall have become false or misleading in any material
respect, and Parent and Sub further agree to take all steps necessary to cause
the Schedule 14D-1 as so corrected to be filed with the SEC and the other Offer
Documents as so corrected to be disseminated to holders of Shares, in each case
as and to the extent required by applicable Federal securities laws. The Company
and its counsel shall be given reasonable opportunity to review and comment upon
the Offer Documents prior to their filing with the SEC or dissemination to the
stockholders of the Company. Parent and Sub agree to provide the Company and its
counsel any comments Parent, Sub or their counsel may receive from the SEC or
its staff with respect to the Offer Documents promptly after the receipt of such
comments.

         (c) Parent shall provide or cause to be provided to Sub on a timely
basis the funds sufficient to accept for payment, and pay for, any and all
Shares that Sub becomes obligated to accept for payment, and pay for, pursuant
to the Offer.

         SECTION 1.02. Company Actions. (a) The Company hereby approves of and
consents to the Offer and represents that the Board of Directors of the Company,
at a meeting duly called and held, duly and unanimously adopted resolutions
approving this Agreement and the Stockholder Agreement, the Offer and the
Merger, determining that the terms of the Offer and the Merger are fair to, and
in the best interests of, the Company's stockholders and recommending that the
Company's stockholders accept the Offer, tender their Shares pursuant to the
Offer and approve and adopt this Agreement (if required). The Company

                                                                               5


represents that its Board of Directors has received the opinion dated February
10, 1997 of Prudential Securities Incorporated ("Prudential Securities") that,
as of such date and based upon and subject to the matters set forth therein, the
cash consideration to be received by the holders of Shares pursuant to the Offer
and the Merger was fair from a financial point of view to such holders, and a
complete and correct signed copy of such opinion has been delivered by the
Company to Parent.

         (b) On the date the Offer Documents are filed with the SEC, or promptly
thereafter, the Company shall file with the SEC a Solicitation/Recommendation
Statement on Schedule 14D-9 with respect to the Offer (such Schedule 14D-9, as
amended from time to time, the "Schedule 14D-9") containing the recommendation
described in paragraph 1.02(a) and shall mail the Schedule 14D-9 to the
stockholders of the Company. The Schedule 14D-9 shall comply as to form in all
material respects with the requirements of the Exchange Act and the rules and
regulations promulgated thereunder and, on the date filed with the SEC and on
the date first published, sent or given to the Company's stockholders, shall not
contain any untrue statement of a material fact or omit to state any material
fact required to be stated therein or necessary in order to make the statements
therein, in light of the circumstances under which they were made, not
misleading, except that no representation or warranty is made by the Company
with respect to written information supplied by Parent or Sub specifically for
inclusion in the Schedule 14D-9. Each of the Company, Parent and Sub agrees
promptly to correct any written information provided by it for use in the
Schedule 14D-9 if and to the extent that such information shall have become
false or misleading in any material respect, and the Company further agrees to
take all steps necessary to amend or supplement the Schedule 14D-9 and to cause
the Schedule 14D-9 as so amended or supplemented to be filed with the SEC and
disseminated to the Company's stockholders, in each case as and to the extent
required by applicable Federal securities laws. Parent and its counsel shall be
given reasonable opportunity to review and comment upon the Schedule 14D-9 prior
to its filing with the SEC or dissemination to stockholders of the Company. The
Company agrees to provide Parent and its counsel any comments the Company or its
counsel may receive from the SEC or its staff with respect to the Schedule 14D-9
promptly after the receipt of such comments.

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


                                   ARTICLE II

                                   The Merger

         SECTION 2.01. The Merger. Upon the terms and subject to the conditions
set forth in this Agreement, and in accordance with the Delaware General
Corporation Law (the "DGCL"), Sub shall be merged with and into the Company at
the Effective Time (as defined in Section 2.03). Following the Effective Time,
the separate corporate existence of Sub shall cease and the Company shall
continue as the surviving corporation (the "Surviving Corporation") and shall
succeed to and assume all the rights and obligations of Sub in accordance with
the DGCL. Notwithstanding the foregoing, Parent may elect at any time prior to
the Merger, instead of merging Sub into the Company as provided above, to merge
the Company with and into Sub. In such event, the parties agree to execute an
appropriate amendment to this Agreement in order to reflect the foregoing and,
where appropriate, to provide that the Sub shall be the Surviving Corporation
and will continue under the name "Innotech, Inc." At the election of Parent, any
direct or indirect wholly owned

                                                                               7


subsidiary (as defined in Section 10.03) of Parent may be substituted for Sub as
a constituent corporation in the Merger. In such event, the parties agree to
execute an appropriate amendment to this Agreement in order to reflect the
foregoing.

         SECTION 2.02. Closing. The closing of the Merger will take place at
10:00 a.m. (New York City time) on a date to be specified by Parent or Sub,
which shall be no later than the second business day after satisfaction or
waiver of the conditions set forth in Article VIII (the "Closing Date"), at the
offices of Cravath, Swaine & Moore, Worldwide Plaza, 825 Eighth Avenue, New
York, New York 10019, unless another date, time or place is agreed to in writing
by the parties hereto.

         SECTION 2.03. Effective Time. Subject to the provisions of this
Agreement, as soon as practicable on or after the Closing Date, the parties
shall file a certificate of merger or other appropriate documents (in any such
case, the "Certificate of Merger") executed in accordance with the relevant
provisions of the DGCL and shall make all other filings or recordings required
under the DGCL and other applicable law. The Merger shall become effective at
such time as the Certificate of Merger is duly filed with the Delaware Secretary
of State, or at such other time specified in the Certificate of Merger as Sub
and the Company shall agree (the time the Merger becomes effective being
hereinafter referred to as the "Effective Time").

         SECTION 2.04. Effects of the Merger. The Merger shall have the effects
set forth in Section 259 of the DGCL.

         SECTION 2.05. Certificate of Incorporation and By-laws. (a) The Second
Amended and Restated Certificate of Incorporation of the Company (the
"Certificate of Incorporation"), as in effect immediately prior to the Effective
Time, shall be the certificate of incorporation of the Surviving Corporation
until thereafter changed or amended as provided therein or by applicable law.

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

         SECTION 2.06. Directors. The directors of Sub immediately prior to the
Effective Time shall be the


<PAGE>   13


                                                                               8


directors of the Surviving Corporation, until the earlier of their resignation
or removal or until their respective successors are duly elected and qualified,
as the case may be.

                  SECTION 2.07. Officers. The officers of the Company
immediately prior to the Effective Time shall be the officers of the Surviving
Corporation, until the earlier of their resignation or removal or until their
respective successors are duly elected and qualified, as the case may be.


                                   ARTICLE III

                Effect of the Merger on the Capital Stock of the
               Constituent Corporations; Exchange of Certificates

                  SECTION 3.01. Effect on Capital Stock. As of the Effective
Time, by virtue of the Merger and without any action on the part of the holder
of any Shares or any shares of capital stock of Sub:

                  (a) Capital Stock of Sub. Each issued and outstanding share of
         capital stock of Sub shall be converted into and become one fully paid
         and nonassessable share of Common Stock, par value $.001 per share, of
         the Surviving Corporation.

                  (b) Cancelation of Treasury Stock and Parent Owned Stock. Each
         Share that is owned by the Company and each Share that is owned by
         Parent, Sub or any other direct or indirect wholly owned subsidiary of
         Parent shall automatically be canceled and retired and shall cease to
         exist, and no consideration shall be delivered in exchange therefor.

                  (c) Conversion of Company Common Stock. Subject to Section
         3.01(d), each issued and outstanding Share (other than Shares to be
         canceled in accordance with Section 3.01(b)) shall be converted into
         the right to receive from the Surviving Corporation in cash, without
         interest, the price actually paid in the Offer (the "Merger
         Consideration"). As of the Effective Time, all such Shares shall no
         longer be outstanding and shall automatically be canceled and retired
         and shall cease to exist, and each holder of a certificate representing
         any such Shares shall cease to have any rights with


<PAGE>   14


                                                                               9


         respect thereto, except the right to receive the Merger
         Consideration, without interest.

                  (d) Shares of Dissenting Stockholders. Notwithstanding
         anything in this Agreement to the contrary, any issued and outstanding
         Shares held by a person (a "Dissenting Stockholder") who has neither
         voted in favor of the Merger nor consented in writing thereto and
         otherwise complies with all the applicable provisions of the DGCL
         concerning the right of holders of Company Common Stock to dissent from
         the Merger and require appraisal of their Shares ("Dissenting Shares")
         shall not be converted as described in Section 3.01(c) but shall become
         the right to receive such consideration as may be determined to be due
         to such Dissenting Stockholder pursuant to the laws of the State of
         Delaware. If, after the Effective Time, such Dissenting Stockholder
         withdraws his demand for appraisal or fails to perfect or otherwise
         loses his right of appraisal, in any case pursuant to the DGCL, his
         Shares shall be deemed to be converted as of the Effective Time into
         the right to receive the Merger Consideration. The Company shall give
         Parent (i) prompt notice of any demands for appraisal of Shares
         received by the Company and (ii) if and after Sub shall have accepted
         for payment Shares pursuant to and subject to the conditions of the
         Offer (including the Minimum Condition) the opportunity to participate
         in and direct all negotiations and proceedings with respect to any such
         demands. The Company shall not, without the prior written consent of
         Parent, make any payment with respect to, or settle, offer to settle or
         otherwise negotiate, any such demands.

                  SECTION 3.02. Exchange of Certificates. (a) Paying Agent.
Prior to the Effective Time, Parent shall designate a substantial bank or trust
company to act as paying agent in the Merger (the "Paying Agent"). Parent shall
cause the Surviving Corporation to deposit with the Paying Agent in separate
trust for holders of the Certificates (as hereinafter defined) immediately
available funds in an amount sufficient for the payment of the aggregate Merger
Consideration for the shares converted pursuant to Section 3.01(c) (it being
understood that any and all interest earned on funds made available to the
Paying Agent pursuant to this Agreement shall be turned over to Parent).

                  (b) Exchange Procedure. As soon as reasonably practicable
         after the Effective Time, the Paying Agent shall mail to each holder of
         record of a certificate or certificates that immediately prior to the
         Effective Time represented Shares (the "Certificates"), (i) a letter of
         transmittal (which shall specify that delivery shall be effected, and
         risk of loss and title to the Certificates shall pass, only upon
         delivery of the Certificates to the Paying Agent and shall be in a form
         and have such other provisions as Parent may reasonably specify) and
         (ii) instructions for use in effecting the surrender of the
         Certificates in exchange for the Merger Consideration. Upon surrender
         of a Certificate for cancelation to the Paying Agent or to such other
         agent or agents as may be appointed by Parent, together with such
         letter of transmittal, duly executed, and such other documents as may
         reasonably be required by the Paying Agent, the holder of such
         Certificate shall be entitled to receive in exchange therefor, and the
         Paying Agent shall pay pursuant to irrevocable instructions given by
         Sub or Parent, the amount of cash into which the Shares theretofore
         represented by such Certificate shall have been converted pursuant to
         Section 3.01, and the Certificate so surrendered shall forthwith be
         canceled. In the event of a transfer of ownership of Shares that is not
         registered in the transfer records of the Company, payment may be made
         to a person other than the person in whose name the Certificate so
         surrendered is registered, if such Certificate shall be properly
         endorsed or otherwise be in proper form for transfer and the person
         requesting such payment shall pay any transfer or other taxes required
         by reason of the payment to a person other than the registered holder
         of such Certificate or establish to the satisfaction of the Surviving
         Corporation that such tax has been paid or is not applicable. Until
         surrendered as contemplated by this Section 3.02, each Certificate
         shall be deemed at any time after the Effective Time to represent only
         the right to receive upon such surrender the amount of cash, without
         interest, into which the Shares theretofore represented by such
         Certificate shall have been converted pursuant to Section 3.01. No
         interest will be paid or will accrue on the cash payable upon the
         surrender of any Certificate.

                  (c) No Further Ownership Rights in Company Common Stock. All
         cash paid upon the surrender of Certificates in accordance with the
         terms of this Article III shall be deemed to have been paid in full
         satisfaction of all rights pertaining to the Shares formerly
         represented by such Certificates. At the Effective Time, the stock
         transfer

                                                                              11


books of the Company shall be closed, and there shall be no further registration
of transfers on the stock transfer books of the Surviving Corporation of the
Shares that were outstanding immediately prior to the Effective Time. If, after
the Effective Time, Certificates are presented to the Surviving Corporation or
the Paying Agent for any reason except notation thereon that a stockholder has
elected to exercise his right to appraisal pursuant to the DGCL they shall be
canceled and exchanged as provided in this Article III.

         (d) No Liability. Any funds deposited with the Paying Agent that remain
unclaimed by the former stockholders of the Company for six (6) months after the
Effective Time shall be paid to the Surviving Corporation upon demand, and any
former stockholders of the Company who have not theretofore complied with the
instructions for exchanging their Certificates provided herein shall thereafter
look only to the Surviving Corporation for payment of their claims for the
Merger Consideration set forth in Section 3.01 hereof for each Share held by
such stockholder, without any interest thereon. None of Parent, Sub, the Company
or the Paying Agent shall be liable to any person in respect of any cash
delivered to a public official pursuant to any applicable abandoned property,
escheat or similar law. If any Certificates shall not have been surrendered
prior to seven years after the Effective Time (or immediately prior to such
earlier date on which any payment pursuant to this Article III would otherwise
escheat to or become the property of any Governmental Entity (as defined in
Section 4.05)), the cash payment in respect of such Certificate shall, to the
extent permitted by applicable law, become the property of the Surviving
Corporation, free and clear of all claims or interests of any person previously
entitled thereto.


                                   ARTICLE IV

                  Representations and Warranties of the Company

business as now being conducted. The Company is duly qualified or licensed to do
business and in good standing in each jurisdiction in which the property owned,
leased or operated by it or the nature of the business conducted by it makes
such qualification or licensing necessary, except in such jurisdictions where
the failure to be so duly qualified or licensed and in good standing could not
reasonably be expected to have a material adverse effect (as defined in Section
10.03) on the Company or prevent or materially delay the consummation of the
Offer and/or the Merger. The Company has made available to Parent complete and
correct copies of its Certificate of Incorporation and By-laws, as amended to
the date of this Agreement.

                  SECTION 4.02. Subsidiaries. The Company has no subsidiaries.

                  SECTION 4.03. Capitalization. The authorized capital stock of
the Company consists of 70,000,000 Shares and 5,000,000 shares of preferred
stock, par value $0.001 per share ("Company Preferred Stock"). At the close of
business on December 31, 1996, (i) 8,955,603 Shares were issued and outstanding,
(ii) 0 Shares were held by the Company in its treasury, (iii) 1,597,250 Shares
were reserved for issuance upon exercise of outstanding Company Stock Options
(as defined in Section 7.04), (iv) 102,482 Shares were issuable upon the
exercise of outstanding warrants and (v) no shares of Company Preferred Stock
were issued and outstanding. Except as set forth above, since December 31, 1996
no shares of capital stock or other voting securities of the Company were
issued, reserved for issuance, issuable or outstanding. All outstanding Shares
are, and all Shares which may be issued will be, when issued, duly authorized,
validly issued, fully paid and nonassessable and not subject to preemptive
rights. 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 stockholders of the
Company may vote. Except as set forth above, as of the date of this Agreement,
there are not any securities, options, warrants, calls, rights, commitments,
agreements, arrangements or undertakings of any kind to which the Company is a
party or by which any of them is bound obligating the Company 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 obligating the Company to
issue, grant, extend or enter into any such security,

obligations of the Company to repurchase, redeem or otherwise acquire any shares
of capital stock of the Company.

                  SECTION 4.04. Authority. The Company has the requisite
corporate power and authority to execute and deliver this Agreement and to
consummate the transactions contemplated hereby (other than, with respect to the
Merger, the approval and adoption of this Agreement by the holders of a majority
of the Shares (the "Company Stockholder Approval")). The execution, delivery and
performance of this Agreement and the consummation by the Company of the Merger
and of the other transactions contemplated hereby have been duly authorized by
all necessary corporate action on the part 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 so contemplated (in each case, other than,
with respect to the Merger, the Company Stockholder Approval). This Agreement
has been duly executed and delivered by the Company and, assuming this Agreement
constitutes a valid and binding obligation of Parent and Sub, constitutes a
valid and binding obligation of the Company enforceable against the Company in
accordance with its terms.

                  SECTION 4.05. Consents and Approvals; No Violations. Except
for filings, permits, authorizations, consents and approvals as may be required

other states in which the Company is qualified to do or is doing business, state
takeover laws and foreign laws, neither the execution, delivery or performance
of this Agreement by the Company nor the consummation by the Company of the
transactions contemplated hereby will (i) conflict with or result in any breach
of any provision of the Certificate of Incorporation or By-laws of the Company,
(ii) require any filing with, or permit, authorization, consent or approval of,
any Federal, state or local government or any court, tribunal, administrative
agency or commission or other governmental or other

regulatory authority or agency, domestic, foreign or supranational (a
"Governmental Entity") (except where the failure to obtain such permits,
authorizations, consents or approvals or to make such filings would not have a
material adverse effect on the Company or prevent or materially delay the
consummation of the Offer and/or the Merger), (iii) except as set forth on
Schedule 4.05, result in a violation or breach of, or constitute (with or
without due notice or lapse of time or both) a default (or give rise to any
right of termination, amendment, cancelation or acceleration) under, any of the
terms, conditions or provisions of any note, bond, mortgage, indenture, lease,
license, contract, agreement or other instrument or obligation to which the
Company is a party or by which it or any of its properties or assets may be
bound or (iv) violate any order, writ, injunction, decree, statute, rule or
regulation applicable to the Company or any of its properties or assets, except
in the case of clauses (iii) or (iv) for violations, breaches or defaults that

Company or prevent or materially delay the consummation of the Offer and/or the
Merger.

                  SECTION 4.06. SEC Documents; Financial Statements. The Company
has filed with the SEC all reports, forms, schedules and statements and other
documents required to be filed by it since March 14, 1996 (the "SEC Documents").

and (ii) none of the SEC Documents 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 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, in all material respects, the consolidated financial position of the
Company as of the

                                                                              15


dates thereof and the results of its operations and cash flows for the periods
then ended (subject, in the case of unaudited statements, to normal year-end
audit adjustments). Except as set forth in the SEC Documents filed and publicly
available prior to the date of this Agreement, and except for liabilities and
obligations incurred in the ordinary course of business consistent with past
practice since the date of the most recent consolidated balance sheet included
in the SEC Documents filed and publicly available prior to the date of this
Agreement and liabilities and obligations that would not, individually or in the
aggregate, have a material adverse effect on the Company, the Company does not
have any liabilities or obligations of any nature (whether accrued, absolute,
contingent or otherwise) required by generally accepted accounting principles to
be set forth on a balance sheet of the Company or in the notes thereto.

                  SECTION 4.07. Information Supplied. None of the information
supplied or to be supplied by the Company in writing for inclusion or
incorporation by reference in (i) the Offer Documents, (ii) the Schedule 14D-9,
(iii) the information to be filed by the Company in connection with the Offer
pursuant to Rule 14f-1 promulgated under the Exchange Act (the "Information

Documents, the Schedule 14D-9 and the Information Statement at the respective
times the Offer Documents, the Schedule 14D-9 and the Information Statement are
filed with the SEC or first published, sent or given to the Company's
stockholders, or in the case of the Proxy Statement, at the time the Proxy
Statement is first mailed to the Company's stockholders or at the time of the
Stockholders Meeting (as defined in Section 7.01), as such Proxy Statement may
be amended or supplemented, 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, the Information Statement and
the Proxy Statement will comply as to form in all material respects with the
requirements of the Exchange Act and the rules and regulations thereunder,
except that no representation or warranty is made by the Company with respect to
statements made or incorporated by reference therein based on information
supplied by Parent or Sub specifically for inclusion or incorporation by
reference therein.

                  SECTION 4.08. Absence of Certain Changes or Events. Except as
disclosed in the SEC Documents (including exhibits thereto) filed and publicly
available prior to the date of this Agreement (the "Filed SEC Documents"), and

or property) with respect to any of the Company's capital stock, (iii) any
split, combination or reclassification of any of its capital stock 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, (iv) (x) any
granting by the Company to any officer of the Company of any increase in

of the most recent audited financial statements included in the Filed SEC
Documents, (y) any granting by the Company to any officer of any increase in
severance or termination pay, except as was required under any employment,

generally accepted accounting principles.

                  SECTION 4.09. Litigation. Except as disclosed in the Filed SEC
Documents and except as disclosed on Schedule 4.09 hereto, there is no suit,
action or proceeding pending or, to the knowledge of the Company, threatened

is there any judgment, decree, injunction, rule or order of any Governmental
Entity or arbitrator


<PAGE>   22


                                                                              17

                  SECTION 4.10. Contracts. Except as disclosed in the Filed SEC
Documents or set forth on Schedule 4.10 and delivered or made available to
Parent, there are no contracts or agreements that are material to the business,
financial condition or results of operations of the Company. The Company is not
in violation of or in default under (nor does there exist any condition which
upon the passage of time or the giving of notice or both would cause such a
violation of or default under) any lease, permit, concession, franchise, license
or any other contract, agreement, arrangement or understanding, to which it is a
party or by which it or any of its properties or assets is bound, except for
violations or defaults that could not, individually or in the aggregate,
reasonably be expected to result in a material adverse affect on the Company.

                  SECTION 4.11. Compliance with Laws. Except as disclosed in the
Filed SEC Documents, the Company is in compliance with all applicable statutes,
laws, ordinances, regulations, rules, judgments, decrees and orders of any
Governmental Entity applicable to its business or operations, except for
instances of actual or possible noncompliance that, individually or in the
aggregate, could not reasonably be expected to have a material adverse effect on
the Company or prevent or materially delay the consummation of the Offer and/or
the Merger. The Company has in effect all Federal, state, local and foreign
governmental approvals, authorizations, certificates, filings, franchises,
licenses, notices, permits and rights, including all authorizations under
Environmental Laws (as defined below) ("Permits"), necessary for it to own,
lease or operate its properties and assets and to carry on its business as now
conducted, except for the failure to have such Permits that, individually or in
the aggregate, could not reasonably be expected to have a material adverse
effect on the Company. There has occurred no default under any Permit, except
for defaults under Permits that, individually or in the aggregate, could not
reasonably be expected to have a material adverse effect on the Company. As of
the date of this Agreement, no investigation or review by any Governmental
Entity with respect to the Company is pending or, to the best knowledge of the
Company, threatened, nor has any Governmental Entity indicated an intention to
conduct any investigation or review, other than, in each case, those the outcome
of which could not be reasonably

                                                                              18

materially delay the consummation of the Offer and/or the Merger.

                  SECTION 4.12. Environmental Matters. Except as set forth in
Schedule 4.12:

                  (i)   the Company is, and has been, in compliance with all
applicable Environmental Laws (as defined below), except for actual or possible
noncompliance which individually or in the aggregate could not reasonably be
expected to have a material adverse effect on the Company. The term
"Environmental Laws" means any Federal, state, provincial, regional, municipal,
local or foreign judgment, order, decree, statute, law, ordinance, rule,
regulation, code, permit, consent, approval, license, writ, decree, directive,
injunction or other enforceable requirement, including any registration
requirement, relating to: (A) Releases (as defined below) or threatened Releases

pollution or protection of health or safety or the environment;

                  (ii)  there has been no Release or threatened Release of
Hazardous Materials, in, on, under or affecting any property now or previously
owned, leased or operated by the Company or, to the knowledge of the Company,
any adjacent site, except in each case for those Releases which individually or
in the aggregate could not be reasonably expected to have a material adverse
effect on the Company. The term "Release" has the meaning set forth in 42 U.S.C.
Section 9601(22). The term "Hazardous Materials" means any pollutant,
contaminant, hazardous, radioactive or toxic substance, material, constituent or
waste, or any other waste, substance, chemical or material regulated under any
Environmental Law, including (1) petroleum, crude oil and any fractions thereof,
(2) natural gas, synthetic gas and any mixtures thereof, (3) asbestos and/or
asbestos-containing material, (4) radon and (5) polychlorinated biphenyls
("PCBs"), or materials or fluids containing PCBs;

                  (iii) the Company has not received any written or, to the
knowledge of any of the Company's senior executive officers, oral, notice of a
pending or threatened action, demand, investigation or inquiry by any
Governmental Entity or other person relating to any actual or potential

                                                                              19


violations of Environmental Law or any actual or potential obligation to
investigate or remediate a Release or threatened Release of any Hazardous
Materials; and

                  (iv) the Company has not assumed, whether by contract or, to
the Company's knowledge, operation of law, any liabilities or obligations
arising under Environmental Laws in connection with formerly owned, leased or
operated properties or facilities or in connection with any formerly owned
divisions, subsidiaries, companies or other entities, except in each case for
those which individually or in the aggregate could not reasonably be expected to
have a material adverse effect on the Company.

                  SECTION 4.13. Absence of Changes in Benefit Plans; Labor
Relations. Except as disclosed in the Filed SEC Documents and except as
disclosed on Schedule 4.13 hereto, since the date of the most recent audited
financial statements included in the Filed SEC Documents, there has not been any
adoption or amendment in any material respect by the Company of any collective
bargaining agreement or any bonus, pension, profit sharing, deferred
compensation, incentive compensation, stock ownership, stock purchase, stock
option, phantom stock, retirement, vacation, severance, disability, death
benefit, hospitalization, medical or other plan or arrangement providing
benefits to any current or former employee, officer or director of the Company.
Except as set forth in Schedule 4.13 or as disclosed in the Filed SEC Documents,
there exist no employment, consulting, severance, termination or indemnification
agreements or arrangements between the Company and any current or former
employee, officer or director of the Company. There are no collective bargaining
or other labor union agreements to which the Company is a party or by which it
is bound. To the best knowledge of the Company, since January 1, 1994, the
Company has not encountered any labor union organizing activity, or had any
actual or threatened employee strikes, work stoppages, slowdowns or lockouts.

                  SECTION 4.14. ERISA Compliance. (i) Schedule 4.14(i) contains
a list and brief description of all "employee pension benefit plans" (as defined
in Section 3(2) of the Employee Retirement Income Security Act of 1974, as
amended ("ERISA")) (sometimes referred to herein as "Pension Plans"), "employee
welfare benefit plans" (as defined in Section 3(1) of ERISA) and all other
benefit plans maintained or contributed to by the Company or any


<PAGE>   25


                                                                              20


other person or entity that, together with the Company, is treated as a single
employer under Section 414(b), (c), (m) or (o) of the Code (the Company and each
such other person or entity, a "Commonly Controlled Entity") for the benefit of
any current or former employees, officers or directors of the Company
(collectively, "Benefit Plans"). The Company has delivered or made available to
Parent true, complete and correct copies of (1) each Benefit Plan (or, in the
case of any unwritten Benefit Plans, descriptions thereof), (2) the most recent
annual report on Form 5500 filed with the Internal Revenue Service with respect
to each Benefit Plan (if any such report was required), (3) the most recent
summary plan description for each Benefit Plan for which such summary plan
description is required and (4) each trust agreement and group annuity contract
relating to any Benefit Plan. Each Benefit Plan has been administered in all
material respects in accordance with its terms. The Company and all the Benefit
Plans are all in compliance in all material respects with applicable provisions
of ERISA and the Code (as defined below).

                  (ii)  Except as disclosed in Schedule 4.14(ii), all Pension
Plans intended to qualify under Section 401(a) of the Code have been the subject
of determination letters from the Internal Revenue Service to the effect that
such Pension Plans are qualified and exempt from Federal income taxes under
Section 401(a) and 501(a), respectively, of the Code, and no such determination
letter has been revoked nor has any such Pension Plan been amended since the
date of its most recent determination letter or application therefor in any
respect that would adversely affect its qualification or materially increase its
costs. All amendments to Pension Plans required under ERISA and the Code to be
adopted by the Company by December 31, 1994, have been adopted.

                  (iii) No Commonly Controlled Entity has within the five year
period immediately preceding the date of this Agreement maintained, contributed
to or been obligated to contribute to any Benefit Plan that is subject to Title
IV of ERISA. No Commonly Controlled Entity is required to contribute to any
"multiemployer plan" (as defined in Section 4001(a)(3) of ERISA) or has
withdrawn from any multiemployer plan where such withdrawal has resulted or
would result in any "withdrawal liability" (within the meaning of Section 4201
of ERISA) that has not been fully paid.

                  (iv)  With respect to any Benefit Plan that is an employee
welfare benefit plan, except as disclosed in Schedule 4.14(iv), (1) no such
Benefit Plan (excluding severance plans) is unfunded or funded through a
"welfare benefits fund", as such term is defined in Section 419(e) of the
Code, (2) each such Benefit Plan that is a "group health plan", as such term is
defined in Section 5000(b)(1) of the Code, complies substantially with the
applicable requirements of Section 4980B(f) of the Code and (3) except as
provided in writing in such plan, there are no understandings, agreements or
undertakings, written or oral, that would prevent any such plan (including any
such plan covering retirees or other former employees) from being amended or
terminated without material liability to the Company on or at any time after the
Effective Time.

                  (v)   Schedule 4.14(v) lists all outstanding Stock Options as 
of December 31, 1996, showing for each such Option: (1) the number of Shares
issuable, (2) the number of vested Shares, (3) the date of grant and (4) the
exercise price.

                  (vi)  Except as set forth on Schedule 4.14(vi) and except with
respect to the Stock Options, no employee of the Company will be entitled to any
additional compensation or benefits or any acceleration of the time of payment
or vesting of any compensation or benefits under any Benefit Plan as a result of
the transactions contemplated by this Agreement. It shall be assumed for
purposes of the preceding sentence that no payments will be received by, or
accelerated to, any such employee as a result of the termination of such
individual's employment by the Surviving Corporation after the Effective Time.

                  SECTION 4.15. Taxes. The Company has filed all tax returns and
reports required to be filed by it and, except with respect to state sales
taxes, has paid all material taxes due and required to be paid by it and, except
with respect to state sales taxes, the most recent financial statements
contained in the Filed SEC Documents reflect an adequate reserve for all taxes
payable by the Company for all taxable periods and portions thereof through the
date of such financial statements. No deficiencies for any taxes which remain
outstanding have been proposed, asserted or assessed against the Company, and no
requests for waivers of the time to assess any such taxes are pending. None of
the Federal income tax returns of the Company have been examined by the United
States Internal Revenue Service. As of

                                                                              22


December 31, 1995, the Company had Federal net operating loss carryforwards (the
"NOL Carryforwards") totalling $21,670,941. The Company had an additional loss
for book purposes of $10,822,452 for 1996. Schedule 4.15 sets forth the periods
during which the NOL Carryforwards arose and the expiration dates of the NOL
Carryforwards, identifies which amounts are currently limited under Section 382
of the Code or the "separate return limitation year" ("SRLY") rules of the
consolidated return regulations, and, in the case of NOL Carryforwards currently
limited under Section 382 of the Code, the relevant Section 382 limitation
(within the meaning of Section 382(b)(1) of the Code). As used in this
Agreement, "taxes" shall mean all Federal, state, local and foreign income,
property, sales, excise and other taxes, tariffs or other governmental charges
in the nature of a tax as well as any interest, penalties and additions to tax.

                  SECTION 4.16. No Excess Parachute Payments. Except as set
forth on Schedule 4.16 and as contained in documents delivered to Parent or its
representatives, no amount that could be received pursuant to the Benefit Plans
or any executed and delivered agreements between the Company and any officer
thereof in effect as of the date of this Agreement (whether in cash or property
or the vesting of property) as a result of any of the transactions contemplated
by this Agreement by any employee, officer or director of the Company who is a
"disqualified individual" (as such term is defined in proposed Treasury
Regulation Section 1.280G-1) under any employment, severance or termination
agreement, other compensation arrangement or Benefit Plan currently in effect
would be an "excess parachute payment" (as such term is defined in Section
280G(b)(1) of the Code). It shall be assumed for purposes of the preceding
sentence that no payments will be received by, or accelerated to, any such
disqualified individual as a result of the termination of such individual's
employment by the Surviving Corporation after the Effective Time. To the best
knowledge of the Company, no disqualified individual is entitled to receive any
additional payment from the Company, the Surviving Corporation, or any other
person referred to in Q&A 10 under proposed Treasury Regulation Section 1.280G-1
(a "Parachute Gross-Up Payment") in the event that the 20 per cent parachute
excise tax of Section 4999(a) of the Code is imposed on such person. The Board
of Directors of the Company has not during the six months prior to the date of
this Agreement granted to any officer, director or employee

                                                                              23


of the Company any right to receive any Parachute Gross-Up Payment.

                  SECTION 4.17. Title to Properties. (i) Except as set forth in
Schedule 4.17, the Company has good and marketable title to, or valid leasehold
interests in or valid rights to, all its material properties and assets except
for such as are no longer used or useful in the conduct of its businesses or as
have been disposed of in the ordinary course of business and except for defects
in title, easements, restrictive covenants and similar encumbrances that, in the
aggregate, do not materially interfere with its ability to conduct its business
as currently conducted. All such material assets and properties, other than
assets and properties in which the Company has a leasehold interest, are free
and clear of all Liens other than those set forth in Schedule 4.17 and except
for Liens that, in the aggregate, do not materially interfere with the ability
of the Company to conduct its business as currently conducted.

                  (ii) Except as set forth in Schedule 4.17, the Company has
complied in all material respects with the terms of all material leases to which
it is a party and under which it is in occupancy, and all such leases are in
full force and effect. The Company enjoys peaceful and undisturbed possession
under all such material leases, except for failures to do so that could not in
the aggregate be reasonably expected to have a material adverse effect on the
Company.

                  SECTION 4.18. Intellectual Property. The Company owns, or is
validly licensed or otherwise has the right to use, without any obligation to
make any fixed or contingent payments, including any royalty payments, all
patents, patent rights, trademarks, trademark rights, trade names, trade name
rights, service marks, service mark rights, copyrights and other proprietary
intellectual property rights and computer programs (certain of which computer
programs may require royalty payments) that are material to the conduct of the
business of the Company as now operated (collectively, "Intellectual Property
Rights"). Schedule 4.18 sets forth a description of all patents, trademarks and
copyrights and applications therefor owned by or licensed to the Company that
are material to the conduct of the business of the Company as now operated.
Except as set forth in Schedule 4.18, no claims are pending or, to the knowledge
of the Company, threatened that the Company is infringing or otherwise adversely
affecting the rights of

                                                                              24


any person with regard to any Intellectual Property Right. To the knowledge of
the Company, except as set forth in Schedule 4.18, no person is infringing the
rights of the Company with respect to any Intellectual Property Right. The
Company has not licensed, or otherwise granted, to any third party, any rights
in or to any Intellectual Property Rights.

                  SECTION 4.19. Distribution Agreements. Schedule 4.19 is a
complete list of all contracts or agreements and such Schedule contains a true
and complete description of any oral arrangements or understandings, to which
the Company is a party relating to the distribution, sale or marketing by third
parties of the Company's products or products licensed by the Company. The
Company has made available to Parent and its representatives true and correct
copies of all contracts and agreements to which the Company is a party relating
to the distribution, sale or marketing by third parties of the Company's
products or products licensed by the Company.

                  SECTION 4.20. Voting Requirements. The affirmative vote of the
holders of a majority of the outstanding Shares is the only vote of the holders
of any class or series of the Company's capital stock necessary to approve this
Agreement and the transactions contemplated by this Agreement.

                  SECTION 4.21. State Takeover Statutes. The Board of Directors
of the Company has approved the Merger, this Agreement and the Stockholder
Agreement, and such approval is sufficient to render inapplicable to the Merger,
this Agreement, the Stockholder Agreement, and the transactions contemplated by
this Agreement and the Stockholder Agreement, the provisions of Section 203 of
the DGCL to the extent, if any, such Section is applicable to the Merger, this
Agreement, the Stockholder Agreement and the transactions contemplated by this
Agreement and the Stockholder Agreement. To the best of the Company's knowledge,
no other state takeover statute or similar statute or regulation applies or
purports to apply to the Merger, this Agreement, the Stockholder Agreement or
the transactions contemplated by this Agreement or the Stockholder Agreement.

                  SECTION 4.22. Brokers; Schedule of Fees and Expenses. No
broker, investment banker, financial advisor or other person, other than
Prudential, the fees and

                                                                              25


expenses of which will be paid by the Company, is entitled to any broker's,
finder's, financial advisor's or other similar fee or commission in connection
with the transactions contemplated by this Agreement based upon arrangements
made by or on behalf of the Company. The fees and expenses incurred and to be
incurred in connection with this Agreement and the transactions contemplated by
this Agreement (other than printing and mailing costs and expenses), including,
without limitation, the fees and expenses of Prudential Securities and the fees
and expenses of the Company's legal counsel (including any counsel retained by
the independent committee of the Board of Directors of the Company or any other
counsel retained to represent the interests of the Company or its shareholders),
shall be as set forth on Schedule 4.22.

                  SECTION 4.23. Opinion of Financial Advisor. The Board of
Directors of the Company has received the opinion dated February 10, 1997 of
Prudential, that, as of such date and based upon and subject to the matters set
forth therein, the cash consideration to be received by holders of Shares
pursuant to the Offer and the Merger was fair from a financial point of view to
such holders, a signed copy of which opinion has been delivered to Parent.


                                    ARTICLE V

                         Representations and Warranties
                                of Parent and Sub

                  Parent and Sub represent and warrant to the Company as
follows:

                  SECTION 5.01. Organization. Each of Parent and Sub is a
corporation duly organized, validly existing and in good standing under the laws
of the jurisdiction of its incorporation and has all requisite corporate power
and authority to carry on its business as now being conducted. Each of Parent
and Sub is duly qualified or licensed to do business and is in good standing in
each jurisdiction in which the nature of its business or the ownership or
leasing of its properties makes such qualifications or licensing necessary,
other than in such jurisdictions where the failure to be so qualified or
licensed (individually or in the aggregate) could not be reasonably expected to
prevent or materially delay the consummation of the Offer and/or the Merger.
Parent has delivered to the Company complete and


<PAGE>   31


                                                                              26


correct copies of its certificate of incorporation and by-laws and the
certificate of incorporation and by-laws of Sub, in each case as amended to the
date of this Agreement.

                  SECTION 5.02. Authority. Parent and Sub have requisite
corporate power and authority to execute and deliver this Agreement and the
Stockholder Agreement, and to consummate the transactions contemplated by this
Agreement and the Stockholder Agreement. The execution, delivery and performance
of this Agreement and the Stockholder Agreement, and the consummation of the
transactions contemplated by this Agreement and the Stockholder Agreement, have
been duly authorized by all necessary corporate action on the part of Parent and
Sub and no other corporate proceedings on the part of Parent and Sub are
necessary to authorize this Agreement or the Stockholder Agreement or to
consummate the transactions contemplated hereby or thereby. No vote of Parent
shareholders is required to approve this Agreement or the Stockholder Agreement
or the transactions contemplated hereby or thereby. Each of this Agreement and
the Stockholder Agreement has been duly executed and delivered by Parent and
Sub, and, assuming such Agreement constitutes a valid and binding obligation of
the other parties thereto, constitutes a valid and binding obligation of Parent
and Sub enforceable against Parent and Sub in accordance with its terms.

                  SECTION 5.03. Consents and Approvals; No Violations. Except
for filings, permits, authorizations, consents and approvals as may be required
under, and other applicable requirements of, the Exchange Act (including the
filing with the SEC of the Offer Documents), the HSR Act, the DGCL, the laws of
other states in which Parent is qualified to do or is doing business, state
takeover laws and foreign laws, neither the execution, delivery or performance
of this Agreement or the Stockholder Agreement by Parent and Sub, nor the
consummation by Parent and Sub of the transactions contemplated hereby or
thereby will (i) conflict with or result in any breach of any provision of the
respective certificate of incorporation or by-laws of Parent and Sub, (ii)
require any filing with, or permit, authorization, consent or approval of, any
Governmental Entity (except where the failure to obtain such permits,
authorizations, consents or approvals or to make such filings would not
reasonably be expected to prevent or materially delay the consummation of the
Offer and/or the Merger), (iii) result in a violation or breach of, or
constitute (with or without due notice or lapse of time or


<PAGE>   32


                                                                              27


both) a default (or give rise to any right of termination, amendment,
cancelation or acceleration) under, any of the terms, conditions or provisions
of any note, bond, mortgage, indenture, license, lease, contract, agreement or
other instrument or obligation to which Parent or any of its subsidiaries is a
party or by which any of them or any of their properties or assets may be bound
or (iv) violate any order, writ, injunction, decree, statute, rule or regulation
applicable to Parent, any of its subsidiaries or any of their properties or
assets, except in the case of clauses (iii) and (iv) for violations, breaches or
defaults which could not, individually or in the aggregate, be reasonably
expected to prevent or materially delay the consummation of the Offer and/or the
Merger.

                  SECTION 5.04. Information Supplied. None of the information
supplied or to be supplied by Parent or Sub specifically for inclusion or
incorporation by reference in (i) the Offer Documents, (ii) the Schedule 14D-9,
(iii) the Information Statement or (iv) the Proxy Statement will, in the case of
the Offer Documents, the Schedule 14D-9 and the Information Statement, at the
respective times the Offer Documents, the Schedule 14D-9 and the Information
Statement are filed with the SEC or first published, sent or given to the
Company's stockholders, or, in the case of the Proxy Statement, at the time the
Proxy Statement is first mailed to the Company's stockholders or at the time of
the Stockholders Meeting, 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 Offer Documents will comply as to form in all
material respects with the requirements of the Exchange Act and the rules and
regulations thereunder, except that no representation or warranty is made by
Parent or Sub with respect to statements made or incorporated by reference
therein based on information supplied by the Company specifically for inclusion
or incorporation by reference therein.

                  SECTION 5.05. Interim Operations of Sub. Sub (and any other
wholly owned subsidiary of Parent which may be used to effect the Offer and the
Merger pursuant to Section 2.01) was formed solely for the purpose of engaging
in the transactions contemplated hereby, has engaged in no other business
activities and has conducted its operations only as contemplated hereby.

                                                                              28


                  SECTION 5.06. Brokers. No broker, investment banker, financial
advisor or other person is entitled to any broker's, finder's, financial
advisor's or other similar fee or commission in connection with the transactions
contemplated by this Agreement based upon arrangements made by or on behalf of
Parent or Sub.

                  SECTION 5.07. Financing. Parent has sufficient funds readily
available to purchase, or to cause Sub to purchase, all the Shares pursuant to
the Offer and the Merger and to pay all fees and expenses payable by Parent or
Sub related to the transactions contemplated by this Agreement.

                  SECTION 5.08. State Takeover Statutes. To the best of Parent's
knowledge, no state takeover statute (other than Section 203 of the DGCL) or
similar statute or regulation applies or purports to apply to the Merger, this
Agreement, the Stockholder Agreement or the transactions contemplated by this
Agreement or the Stockholder Agreement.


                                   ARTICLE VI

                                    Covenants

                  SECTION 6.01. Conduct of Business. During the period from the
date of this Agreement to the Effective Time or termination of this Agreement
pursuant to Section 9.01 hereof, except as otherwise contemplated hereby or to
the extent that Parent shall otherwise consent in writing, the Company shall
carry on its business in the ordinary course consistent with the manner as
heretofore conducted and, to the extent consistent therewith, use reasonable
efforts to preserve intact its current business organization, keep available the
services of its current officers and employees and preserve its relationships
with customers, suppliers, licensors, licensees, distributors and others having
significant business dealings with it. Without limiting the generality of the
foregoing, during the period from the date of this Agreement to the Effective

action to facilitate, any inquiries or the making of any proposal that
constitutes, or may reasonably be expected to lead to, any Takeover Proposal or
(ii) participate in any discussions or negotiations regarding any Takeover
Proposal; provided, however, that if, at any time prior to the acceptance for
payment of Shares pursuant to and subject to the conditions (including the
Minimum Condition) of the Offer, the Board of Directors of the Company (or its
Special Committee)

                                                                              32


determines in good faith, after consultation with outside counsel, that failure
to do so would create a substantial risk of liability for breach of its
fiduciary duties to the Company's stockholders under applicable law, the Company
may, in response to a Takeover Proposal that was unsolicited or that did not
otherwise result from a breach of this Section 6.02(a), and subject to
compliance with Section 6.02(c), (x) furnish information with respect to the
Company to any person pursuant to a customary and reasonable confidentiality
agreement and (y) participate in negotiations regarding such Takeover Proposal.
Without limiting the foregoing, it is understood that any violation of the
restrictions set forth in the preceding sentence by any director or officer of
the Company or any investment banker, financial advisor, attorney, accountant or
other representative of the Company's, acting on behalf of the Company, shall be
deemed to be a breach of this Section 6.02(a) by the Company. For purposes of
this Agreement, "Takeover Proposal" means any proposal or offer from any person
relating to any direct or indirect acquisition or purchase of 20% or more of the
assets of the Company or 20% or more of any class of outstanding equity
securities of the Company, any tender offer or exchange offer that if
consummated would result in any person beneficially owning 20% or more of any
class of equity securities of the Company or any merger, consolidation, business
combination, sale of substantially all the assets, recapitalization,
liquidation, dissolution or similar transaction involving the Company, other
than the transactions contemplated by this Agreement.

                  (b) Neither the Board of Directors of the Company nor any
committee thereof shall (i) withdraw or modify, or propose to withdraw or
modify, in a manner adverse to Parent, the approval or recommendation by such
Board of Directors or such committee of the Offer, this Agreement or the Merger,
(ii) approve or recommend, or propose to approve or recommend, any Takeover
Proposal or (iii) cause the Company to enter into any letter of intent,
agreement in principle, acquisition agreement or other agreement (an
"Acquisition Agreement") with respect to any Takeover Proposal unless the Board
of Directors of the Company shall have terminated this Agreement pursuant to
Section 9.01(d).

                  (c) In addition to the obligations of the Company set forth in
paragraphs (a) and (b) of this Section 6.02, the Company shall immediately
advise Parent orally and in writing of any request for information or of any
Takeover Proposal or any inquiry regarding the making of a Takeover


<PAGE>   38


                                                                              33


Proposal, the material terms and conditions of such request, Takeover Proposal
or inquiry and the identity of the person making such request, Takeover Proposal
or inquiry. The Company will, to the extent reasonably practicable, keep Parent
fully informed of the status and details (including amendments or proposed
amendments) of any such request, Takeover Proposal or inquiry.

                  (d) Nothing contained in this Section 6.02 shall prohibit the
Company from at any time taking and disclosing to its stockholders a position
contemplated by Rule 14e-2(a) promulgated under the Exchange Act or from making
any disclosure to the Company's stockholders if, in the good faith judgment of
the Board of Directors of the Company (or its Special Committee), after
consultation with outside counsel, failure so to disclose would create a
substantial risk of liability for breach of its fiduciary duties to the
Company's stockholders under applicable law; provided, however, neither the
Company nor its Board of Directors nor any committee thereof shall, except as
permitted by Section 6.02(b), withdraw or modify, or propose to withdraw or
modify, its position with respect to the Offer, the Merger or this Agreement or
approve or recommend, or propose to approve or recommend, a Takeover Proposal;
provided, further, that the taking of a position by the Company pursuant to Rule
14e-2(a)(2) or (3) of the Exchange Act in respect of a Takeover Proposal shall
not be deemed a withdrawal, a modification or a proposal to do either, of its
position with respect to the Offer or the Merger for purposes hereof.

                  SECTION 6.03. Certain Tax Matters. From the date hereof until
the Effective Time, (i) the Company will file all tax returns and reports
("Post-Signing Returns") required to be filed; (ii) the Company will timely pay
all taxes shown as due and payable on the Company's Post-Signing Returns that
are so filed; (iii) the Company will make provision for all taxes payable by the
Company for which no Post-Signing Return is due prior to the Effective Time; and
(iv) the Company will promptly notify Parent of any action, suit, proceeding,
claim or audit pending against or with respect to the Company in respect of any
tax where there is a reasonable possibility of a determination or decision which
would reasonably be expected to have a significant adverse effect on the
Company's tax liabilities or tax attributes.

                  SECTION 6.04. Other Actions. The Company shall not take any
action that could reasonably be expected to result in (i) any of the
representations and warranties of the Company set forth in this Agreement that
are qualified as to materiality becoming untrue, (ii) any of such
representations and warranties that are not so qualified becoming untrue in any
material respect or (iii) any of the Offer Conditions not being satisfied
(subject to the Company's right to take actions specifically permitted by
Section 6.02 or 9.01).

                  SECTION 6.05. Advice of Changes; Filings. The Company shall
confer with Parent on a regular and frequent basis as reasonably requested by
Parent, report on operational matters and promptly advise Parent orally and, if
requested by Parent, in writing of any material adverse change with respect to
the Company. The Company shall promptly provide to Parent (or its counsel)
copies of all filings made by the Company with any Governmental Entity in
connection with this Agreement and the transactions contemplated hereby.

                              Additional Agreements

                  SECTION 7.01. Stockholder Approval; Preparation of Proxy
Statement. (a) If the Company Stockholder Approval is required by law, the
Company will, as soon as practicable following the acceptance for payment of,
and payment for, Shares by Sub pursuant to and subject to the conditions
(including the Minimum Condition) of the Offer, duly call, give notice of,
convene and hold a meeting of its stockholders (the "Stockholders Meeting") for
the purpose of obtaining the Company Stockholder Approval. The Company will,
through its Board of Directors, recommend to its stockholders that the Company
Stockholder Approval be given. Notwithstanding the foregoing, if Sub or any
other subsidiary of Parent shall acquire at least 90% of the outstanding Shares,
the parties shall, at the request of Parent, take all necessary and appropriate
action to cause the Merger to become effective as soon as practicable after the
expiration of the Offer without a Stockholders Meeting in accordance with
Section 253 of the DGCL.

                  (b) If the Company Stockholder Approval is required by law,
the Company will, at Parent's request, as


<PAGE>   40


                                                                              35


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

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

                  SECTION 7.02. Access to Information; Confidentiality. The
Company shall afford to Parent, and to Parent's officers, employees,
accountants, counsel, financial advisers and other representatives, reasonable
access during normal business hours during the period prior to the Effective
Time or termination of this Agreement pursuant to Section 9.01 hereof to all
their respective properties, books, contracts, commitments, personnel and
records and, during such period, the Company shall furnish promptly to Parent
(a) a copy of each report, schedule, registration statement and other document
filed by it during such period pursuant to the requirements of Federal or state
securities laws and (b) all other information concerning its business,
properties and personnel as Parent may reasonably request. Except as required by
law, Parent will hold, and will cause its officers, employees, accountants,
counsel, financial advisers and other representatives and affiliates to hold,
any and all information received from the Company, directly or indirectly, in
confidence, according to the



<PAGE>   41
                                                                          36

terms of the confidentiality agreement dated as of November 27, 1995, among the
Company, Parent and Johnson & Johnson Vision Products, as amended on August 1,
1996 and January 31, 1997 (as amended, the "Confidentiality Agreement").

                  SECTION 7.03. Reasonable Efforts; Notification. (a) Upon the
terms and subject to the conditions set forth in this Agreement, each of the
parties agrees to use all reasonable efforts to take, or cause to be taken, all
actions, and to do, or cause to be done, and to assist and cooperate with the
other parties in doing, all things necessary, proper or advisable to consummate
and make effective, in the most expeditious manner practicable, the Offer and
the Merger, and the other transactions contemplated by this Agreement, including
(i) the obtaining of all necessary actions or nonactions, waivers, consents and
approvals from Governmental Entities and the making of all necessary
registrations and filings (including filings with Governmental Entities, if any)
and the taking of all reasonable steps as may be necessary to obtain an approval
or waiver from, or to avoid an action or proceeding by, any Governmental Entity,
(ii) the obtaining of all necessary consents, approvals or waivers from this
parties, (iii) the defending of any lawsuits or other legal proceedings, whether
judicial or administrative, challenging this Agreement or the consummation of
any of the transactions contemplated by this Agreement, including seeking to
have any stay or temporary restraining order entered by any court or other
Governmental Entity vacated or reversed and (iv) the execution and delivery of
any additional instruments necessary to consummate the transactions contemplated
by, and to fully carry out the purposes of, this Agreement. In connection with
and without limiting the foregoing, the Company 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 Offer, the Merger,
this Agreement, the Stockholder Agreement or any of the other transactions
contemplated by this Agreement or the Stockholder Agreement and (ii) if any
state takeover statute or similar statute or regulation becomes applicable to
the Offer, the Merger, this Agreement, the Stockholder Agreement or any other
transaction contemplated by this Agreement or the Stockholder Agreement, at
Parent's sole cost take all action reasonably necessary to ensure that the
Offer, the Merger and the other transactions contemplated by this Agreement may
be consummated as promptly as practicable on the terms
<PAGE>   42
                                                                        37

contemplated by this Agreement and otherwise to minimize the effect of such
statute or regulation on the Offer, the Merger, this Agreement, the Stockholder
Agreement and the other transactions contemplated by this Agreement or the
Stockholder Agreement. Nothing in this Agreement shall be deemed to require
Parent to dispose of any significant asset or collection of assets.

                  (b) The Company shall give prompt notice to Parent of (i) any
representation or warranty made by it contained in this Agreement that it
qualified as to materiality becoming untrue or inaccurate in any respect or any
such representation or warranty that is not so qualified becoming untrue or
inaccurate in any material respect or (ii) the failure by it to comply with or
satisfy in any material respect any covenant, condition or agreement to be
compiled with or satisfied by it under this Agreement; provided, however, that
no such notification shall affect the representations, warranties, covenants or
agreement of the parties or the conditions to the obligations of the parties
under this Agreement.

                  SECTION 7.04. Stock Option Plans and Warrants. (a) As soon as
practicable following the date of this Agreement but in no event later than the
consummation of the Offer, the Company (or, if appropriate, the Board of
Directors of the Company or any committee administering the Stock Option Plans
(as defined below)) shall (including by adopting resolutions or taking any other
actions) ensure that, except as set forth on Schedule 7.04(a), each outstanding
option to purchase Shares (a "Company Stock Option") heretofore granted under
any stock option, stock appreciation rights or stock purchase plan, program or
arrangement of the Company (collectively, the "Stock Option Plans") and each
outstanding warrant to purchase Shares (a "Warrant") in each case outstanding
immediately prior to the consummation of the Offer, whether or not then
exercisable, shall either (x) be cancelled immediately prior to the Effective
Time in exchange for an amount in cash, payable at the time of such
cancellation, equal to the product of (y) the number of Shares subject to such
Company Stock Option or Warrant immediately prior to the Effective Time and (z)
the excess of the price per Share to be paid in the Offer over the per Share
exercise price of such Company Stock Option or Warrant (the "Net Amount") or (y)
be converted immediately prior to the Effective Time into the right solely to
receive the Net Amount; provided, however, that no such cash payment has been
made. The Company (or,
<PAGE>   43
                                                                         38

if appropriate, the Board of Directors of the Company or any committee
administering the Stock Option Plans) shall use its reasonable best efforts to
ensure that immediately prior to the Effective Time the Company Stock Options
and Warrants set forth on Schedule 7.04(a) are cancelled or converted as set
forth above. The Company shall not make, or agree to make, any payment of any
kind to any holder of a Company Stock Option or a Warrant (except for the
payment described above) without the consent of Parent (which consent will not
be unreasonably withheld).

                  (b) Subject to Section 7.04(a), all Stock Option Plans shall
terminate as of the Effective Time and the provisions in any other Benefit Plan
providing for the issuance, transfer or grant of any capital stock of the
Company or any interest in respect of any capital stock of the Company shall be
deleted as of the Effective Time. The Company shall ensure that following the
consummation of the Offer, other than with respect to the Company Stock Options
and Warrants set forth on Schedule 7.04(a), no holder of a Company Stock Option
or Warrant or any participant in any Stock Option Plan shall have any right
thereunder to acquire any capital stock of the Company, Parent or the Surviving
Corporation, and the Company shall use its reasonable best efforts to ensure
that following the Effective Time, no holder of a Company Stock Option or
Warrant set forth on Schedule 7.04(a) or any participant in any Stock Option
Plan shall have any right thereunder to acquire any capital stock of the
Company, Parent or the Surviving Corporation.

                  (c) The Surviving Corporation shall continue to be obligated
to pay the Net Amount to holders of any Company Stock Options or Warrants
converted in accordance with clause (y) of Section 7.04(a).

                  SECTION 7.05. Indemnification, Exculpation and Insurance. (a)
Parent agrees that all rights to indemnification and exculpation (including the
advancement of expenses) from liabilities for acts or omissions occurring at or
prior to the Effective Time (including with respect to the transactions
contemplated by this Agreement) existing now or at the Effective Time in favor
of the current or former directors or officers of the Company as provided in its
Certificate of Incorporation, its By-laws (each as in effect on the date hereof)
and reasonable indemnification agreements shall be assumed by the Surviving
Corporation in the Merger, without further action, as of the Effective Time and
shall survive the Merger and shall
<PAGE>   44
                                                                         39

continue in full force and effect without amendment, modification or repeal in
accordance with their terms for a period of not less than six years after the
Effective Time; provided however, that if any claims are asserted or made within
such six year period, all rights to indemnification (and to advancement of
expenses) hereunder in respect of any such claims shall continue, without
diminution, until disposition of any and all such claims.

                  (b) In the event that Parent, the Surviving Corporation or any
of their successors or assigns (i) consolidates with or merges into any other
person and is not the continuing or surviving corporation or entity of such
consolidation or merger or (ii) transfers or conveys all or substantially all of
its properties and assets to any person, then, and in each such case, proper
provision will be made so that the successors and assigns of Parent or the
Surviving Corporation, as the case may be, shall assume the obligations set
forth in this Section 7.05. In the event the Surviving Corporation transfers any
material portion of its assets, in a single transaction or in a series of
transactions, Parent will either guarantee the indemnification obligations
referred to in Section 7.05(a) or take such other action to insure that the
ability of the Surviving Corporation, legal and financial, to satisfy such
indemnification obligations will not be diminished in any material respect.

                  (c) For six years after the Effective Time, Parent shall,
unless Parent agrees in writing to guarantee the indemnification obligations set
forth in Section 7.05(a), provide officers' and directors' liability insurance
in respect of acts or omissions occurring at or prior to the Effective Time,
including but not limited to the transactions contemplated by this Agreement,
covering each person currently covered by the Company's officers' and directors'
liability insurance policy, or who becomes covered by such policy prior to the
Effective Time, on terms with respect to coverage and amount no less favorable
than those of such policy in effect on the date hereof, provided that in
satisfying its obligation under this Section Parent shall not be obligated to
pay premiums in excess of 200% of the amount per annum the Company paid in its
last full fiscal year (which the Company represents to be $129,000), and
provided further that Parent shall nevertheless be obligated to provide such
coverage as may be obtained for such 200% amount.

                                                                         40

                  (d) The provisions of this Section 7.05 (i) are intended to be
for the benefit of, and will be enforceable by, each indemnified party, his or
her heirs and his or her representatives and (ii) are in addition to, and not in
substitution for, any other rights to indemnification or contribution that any
such person may have by contract or otherwise.

                  SECTION 7.06. Directors. Promptly upon the acceptance for
payment of, and payment for, any Shares by Sub pursuant to and subject to the
conditions (including the Minimum Condition) of the Offer, Sub shall be entitled
to designate such number of directors on the Board of Directors of the Company
as will give Sub, subject to compliance with Section 14(f) of the Exchange Act,
a majority of such directors, and the Company shall, at such time, cause Sub's
designees to be so elected by its existing Board of Directors. Subject to
applicable law, the Company shall take all action requested by Parent necessary
to effect any such election, including mailing to its stockholders the
Information Statement containing the information required by Section 14(f) of
the Exchange Act and Rule 14f-1 promulgated thereunder, and the Company agrees
to make such mailing with the mailing of the Schedule 14D-9 (provided that Sub
shall have provided to the Company on a timely basis in writing all information
required to be included in the Information Statement with respect to Sub's
designees). In connection with the foregoing, the Company will promptly, at the
option of Parent, either increase the size of the Company's Board of Directors
and/or obtain the resignation of such number of its current directors as is
necessary to enable Sub's designees to be elected or appointed to, and to
constitute a majority of, the Company's Board of Directors as provided above.

                  SECTION 7.07. Fees and Expenses. (a) Except as otherwise
provided herein and as provided below in this Section 7.07, all fees and
expenses incurred in connection with the Offer, the Merger, this Agreement and
the transactions contemplated by this Agreement shall be paid by the party
incurring such fees or expenses, whether or not the Offer or the Merger is
consummated, except that printing and mailing costs and expenses shall be shared
equally by Parent and the Company.

                  (b) In the event that this Agreement is terminated by any
party hereto pursuant to Section 9.01(d), the Company shall promptly, but in no
event later than two days after
<PAGE>   46
                                                                         41

the date of such termination, pay Parent a fee equal to $6.25 million in
immediately available funds (the "Termination Fee") and all Expenses (as defined
below). If, at the time of any other termination of this Agreement (other than
pursuant to Section 9.01(a) or Section 9.01(b)(ii) or by the Company pursuant to
Section 9.01(e)), a Takeover Proposal shall have been made (other than a
Takeover Proposal made solely to a Stockholder (as defined in the Stockholder
Agreement) unless and until such Takeover Proposal becomes known to the Company
(other than knowledge imputed to the Company by virtue of a direct relationship
of such Stockholder with an officer or director of the Company) or becomes
publicly known) and prior to December 31, 1997 the Company shall either (x)
consummate a Trigger Takeover Proposal or (y) enter into an Acquisition
Agreement providing for a Trigger Takeover Proposal, then the Company shall pay
the Termination Fee and all Expenses in the case of clause (x) concurrently with
the consummation of such Trigger Takeover Proposal or in the case of clause (y)
concurrently with the consummation of the transaction subject to such
Acquisition Agreement (whether or not such transaction is consummated prior to
December 31, 1997); provided, however, that no Termination Fee and no Expenses
will be payable pursuant to this sentence if the Offer is terminated prior to
its scheduled expiration date (without giving effect to any voluntary or
required extensions thereof) or if at the time this Agreement is terminated, the
Minimum Condition shall have been satisfied but any of the other conditions to
the Offer shall not have been satisfied. The Company acknowledges that the
agreements contained in this Section 7.07(b) are an integral part of the
transactions contemplated by this Agreement, and that, without these agreements,
Parent would not enter into this Agreement; accordingly, if the Company fails
promptly to pay the amount due pursuant to this Section 7.07(b), and, in order
to obtain such payment, Parent commences a suit which results in a judgment
against the Company for the fee set forth in this Section 7.07(b), the Company
shall pay to Parent its reasonable costs and expenses (including attorneys' fees
and expenses) in connection with such suit, together with interest on the amount
of the fee at the prime rate of Chase Manhattan Bank, N.A. in effect on the date
such payment was required to be made. A "Trigger Takeover Proposal" shall have
the meaning assigned to the term "Takeover Proposal" in Section 6.02(a) except
that references to "20%" in such definition shall be deemed to be references to
"40%" and a Trigger Takeover Proposal may only be in the form of a single
transaction or a series of
<PAGE>   47
                                                                         42

related transactions. "Expenses" shall mean all out-of-pocket expenses incurred
by Parent and Sub in connection with this Agreement, the Stockholder Agreement
and the transactions contemplated hereby and thereby in an amount not to exceed
$500,000, payable in immediately available funds.

                  SECTION 7.08. Public Announcements. Parent and Sub, on the one
hand, and the Company, on the other hand, will consult with each other before
issuing, and provide each other the opportunity to review and comment upon, any
press release or other public statements with respect to the transactions
contemplated by this Agreement, including the Offer and the Merger, and shall
not issue any such press release or make any such public statement prior to such
consultation, except as may be required by applicable law, court process or by
obligations pursuant to any listing agreement with any national securities
exchange or national securities quotation system. The parties agree that the
initial press release to be issued with respect to the transactions contemplated
by this Agreement shall be in the form heretofore agreed to by the parties.

                SECTION 7.09. Continuation of Benefits. Parent shall cause the
Surviving Corporation to take such actions as are necessary so that, for a
period of not less than one year after the Effective Time, employees of the
Company who continue their employment after the Effective Time will be provided
employee benefits which in the aggregate are at least generally comparable in
the aggregate to those provided to such employees as of the date hereof. It is
Parent's current intention that, following the first anniversary of the
Effective Time, Parent will provide employee benefit plans, programs,
arrangements and policies for the benefit of such employees of the Company which
are generally comparable in the aggregate to the employee benefit plans,
programs, arrangements and policies for the benefit of other similarly situated
employees of Parent and its subsidiaries.

                  SECTION 7.10. Stop Transfer. The Company shall not register
the transfer of any certificate representing any Subject Shares (as defined in
the Stockholder Agreement), unless such transfer is made to Parent or Sub or
otherwise in compliance with the Stockholder Agreement. The Company will
inscribe upon any certificates representing Subject Shares tendered by a
Stockholder (as defined in the Stockholder Agreement) for such purpose the
following

                                                                       43

the Merger. The respective obligation of each party to effect the Merger shall

conditions:

                  (a) Company Stockholder Approval. If required by applicable
         law, the Company Stockholder Approval shall have been obtained;
         provided that Parent and Sub shall vote all their Shares in favor of
         the Merger.

                  (b) No Injunctions or Restraints. No statute, rule,
         regulation, executive order, decree, temporary restraining order,
         preliminary or permanent injunction or other order issued by any court
         of competent jurisdiction or other Governmental Entity or other legal
         restraint or prohibition preventing the consummation of the Merger
         shall be in effect; provided, however, that each of the parties shall
         have used reasonable efforts to prevent the entry of any such
         injunction or other order and to appeal as promptly as possible any
         injunction or other order that may be entered.

                  (c) Purchase of Shares. Sub shall have previously accepted for
         payment and paid for Shares pursuant to and subject to the conditions

                            Termination and Amendment

                  SECTION 9.01. Termination. This Agreement may be terminated at
any time prior to the Effective Time, whether before or after approval of the
terms of this Agreement by the stockholders of the Company:

                  (a) by mutual written consent of Parent and the Company;

                  (b) by either Parent or the Company:

                           (i) if (x) as a result of the failure of any of the
                  Offer Conditions the Offer shall have terminated or expired in
                  accordance with its terms without Sub having accepted for
                  payment Shares pursuant to and subject to the conditions
                  (including the Minimum Condition) of the Offer or (y) Sub
                  shall not have accepted for payment Shares pursuant to the
                  Offer prior to May 31, 1997; provided, however, that the right
                  to terminate this Agreement pursuant to this Section
                  9.01(b)(i) shall not be available to any party whose failure
                  to perform any of its obligations under this Agreement results
                  in the failure of any such condition or if the failure of such
                  condition results from facts or circumstances that constitute
                  a material breach of representation or warranty under this
                  Agreement by such party unless such breach was not willful or
                  intentional; or

                          (ii) if any Governmental Entity shall have issued an
                  order, decree or ruling or taken any other action permanently
                  enjoining, restraining or otherwise prohibiting the acceptance
                  for payment of, or payment for, Shares pursuant to the Offer
                  or the Merger and such order, decree or ruling or other action
                  shall have become final and nonappealable;

                  (c) by Parent or Sub prior to Sub's obligation to accept
         Shares for payment pursuant to the Offer in the event of a breach by
         the Company of any representation, warranty, covenant or other
         agreement contained in this Agreement which (i) would give rise to the
         failure of a condition set forth in paragraph (d) or (e) of
<PAGE>   50
                                                                        45

         Exhibit A and (ii) cannot be or has not been cured within 20 days after
         the giving of written notice to the Company;

                  (d) by either Parent or the Company if, prior to the
         obligation of Sub to accept Shares for payment pursuant to the Offer,
         the Board of Directors of the Company determines that a Takeover
         Proposal constitutes a Superior Proposal (as defined below); provided,
         however, that the Company may not terminate this Agreement pursuant to
         this Section 9.01(d) unless and until five business days have elapsed
         following delivery to Parent of a written notice of such determination
         by the Board of Directors of the Company and during such five business
         day period the Company (i) informs Parent of the terms and conditions
         of the Takeover Proposal and the identity of the person making the
         Takeover Proposal and (ii) otherwise cooperates with Parent with
         respect thereto (subject, in the case of this clause (ii), to the
         condition that the Board of Directors of the Company shall not be
         required to take any action that it believes, after consultation with
         outside legal counsel, would present a substantial risk of liability
         for violating its obligations to the Company or the Company's
         stockholders under applicable law) with the intent of enabling Parent
         to agree to a modification of the terms and conditions of this
         Agreement so that the transactions contemplated hereby may be effected;
         provided, further, that the Company may not terminate this Agreement
         pursuant to this Section 9.01(d) unless at the end of such five
         business day period the Board of Directors of the Company continues to
         believe that the Takeover Proposal constitutes a Superior Proposal and
         no later than two days thereafter the Company pays to Parent the amount
         specified under Section 7.07(b) pursuant to the terms of such Section
         7.07(b); and provided, further, that in the event the determination of
         the Board of Directors of the Company that a Takeover Proposal
         constitutes a Superior Proposal is made less than ten business days
         prior to the scheduled expiration of the Offer, Parent and Sub will
         either (x) reduce the period described in the first proviso of this
         Section 9.01(d) or (y) extend the Offer, in either case such that the
         period described in the first proviso of this Section 9.01(d) will end
         no later than five business days prior to the expiration of the Offer.
         For purposes of this Agreement, a "Superior Proposal" means any bona
         fide

         proposal made by a third party to acquire, directly or indirectly, for
         consideration consisting of cash and/or securities, more than 50% of
         the voting power of the Shares of or all or substantially all the
         assets of the Company and otherwise on terms which the Board of
         Directors of the Company determines in its good faith judgment (based
         on the written opinion of a financial advisor of nationally recognized
         reputation (which opinion shall be provided to Parent)) to be more
         favorable to the Company's stockholders than the Offer and the Merger
         and for which financing, to the extent required, is then committed or
         which, in the good faith judgment of the Board of Directors of the
         Company, is capable of being obtained by such third party; or

                  (e) by the Company, if Sub or Parent shall have (A) failed to
         commence the Offer within five business days of the date hereof, (B)
         failed to pay for Shares pursuant to the Offer in accordance with
         Section 1.01(a) hereof or (C) breached in any material respect any of
         their respective representations, warranties, other covenants or other
         agreements contained in this Agreement, which breach or failure to
         perform in respect of clause (C) is incapable of being cured or has not
         been cured within 20 days after the giving of written notice to Parent
         or Sub, as applicable, except, in any case under clause (C), such
         breaches and failures which are not reasonably likely to affect
         adversely Parent's or Sub's ability to complete the Offer or the Merger
         subject to the terms and conditions of this Agreement.

                  SECTION 9.02. Effect of Termination. In the event of a
termination of this Agreement by either the Company or Parent as provided in
Section 9.01, this Agreement shall forthwith become void and there shall be no
liability or obligation on the part of Parent, Sub or the Company or their
respective officers or directors, except with respect to the last sentence of
Section 1.02(c), Section 5.06, the last sentence of Section 7.02, Section 7.07,
Section 9.01, this Section 9.02 and Article X; provided, however, that nothing
herein shall relieve any party for liability for any breach hereof.

                  SECTION 9.03. Amendment. This Agreement may be amended by the
parties hereto, by action taken or authorized by their respective Boards of
Directors, at any time before or after obtaining the Company Stockholder
Approval (if
<PAGE>   52
                                                                        47

required by law), but, after any such approval, no amendment shall be made which
by law requires further approval by such shareholders without obtaining such
further approval. This Agreement may not be amended except by an instrument in
writing signed on behalf of each of the parties hereto.

                  SECTION 9.04. Extension; Waiver. At any time prior to the
Effective Time, the parties hereto, by action taken or authorized by their
respective Boards of Directors, may, to the extent legally allowed, (i) extend
the time for the performance of any of the obligations or other acts of the
other parties hereto, (ii) waive any inaccuracies in the representations and
warranties contained herein or in any document delivered pursuant hereto or
(iii) subject to Section 9.03, waive compliance with any of the agreements or
conditions contained herein. Any agreement on the part of a party hereto to any
such extension or waiver shall be valid only if set forth in a written
instrument signed on behalf of such party. The failure of any party to this
Agreement to assert any of its rights under this Agreement or otherwise shall
not constitute a waiver of those rights.

                  SECTION 9.05. Procedure for Termination, Amendment, Extension
or Waiver. A termination of this Agreement pursuant to Section 9.01, an
amendment of this Agreement pursuant to Section 9.03 or an extension or waiver
pursuant to Section 9.04 shall, in order to be effective, require in the case of
Parent, Sub or the Company, action by its Board of Directors or the duly
authorized designee of its Board of Directors; provided, however, that in the
event that Sub's designees are appointed or elected to the Board of Directors of
the Company as provided in Section 7.06, after the acceptance for payment and
payment of Shares pursuant to and subject to the Conditions (including the
Minimum Condition) of the Offer and prior to the Effective Time, the affirmative
vote of a majority of the directors of the Company that were not designated by
Parent or Sub shall be required by the Company to (i) amend or terminate this
Agreement by the Company, (ii) exercise or waive any of the Company's rights or
remedies under this Agreement, (iii) extend the time for performance of Parent's
and Sub's respective obligations under this Agreement or (iv) take any action to
amend or otherwise modify the Company's Certificate of Incorporation or By-laws.

to this Agreement shall survive the Effective Time or, in the case of the
Company, shall survive the acceptance for payment of, and payment for, Shares by
Sub pursuant to the Offer. This Section 10.01 shall not limit any covenant or
agreement of the parties which by its terms contemplates performance after the
Effective Time of the Merger.

                  SECTION 10.05. Entire Agreement; Third Party Beneficiaries.
This Agreement and the Confidentiality Agreement (including the documents and
the instruments referred to herein, but excluding Section 4 of the
Confidentiality Agreement which Section shall not survive the date hereof) (a)

                             CONDITIONS OF THE OFFER

                  Notwithstanding any other term of the Offer, Sub shall not be
required to accept for payment or, subject to any applicable rules and
regulations of the SEC, including Rule 14e-1(c) under the Exchange Act (relating
to Sub's obligation to pay for or return tendered Shares after the termination
or withdrawal of the Offer), to pay for any Shares tendered pursuant to the
Offer unless (i) there shall have been validly tendered and not withdrawn prior
to the expiration of the Offer (x) such number of Shares that together with
Shares subject to the Stockholder Agreement that shall not have been tendered
would constitute a majority of the Shares (for purposes of this clause (x) only,
"Shares" shall be deemed to refer only to Shares outstanding on the date hereof)
and (y) such number of Shares that together with Shares subject to the
Stockholder Agreement that shall not have been tendered would constitute a
majority of the fully diluted Shares as of the date of determination (determined
on a fully diluted basis for all outstanding stock options and any other rights
to acquire Shares) (the conditions in (x) and (y) collectively, the "Minimum
Condition") and (ii) any waiting period under the HSR Act applicable to the
purchase of Shares pursuant to the Offer shall have expired or been terminated.
Furthermore, notwithstanding any other term of the Offer, Sub shall not be
required to accept for payment or, subject as aforesaid, to pay for any Shares
not theretofore accepted for payment or paid for, and may terminate the Offer
if, at any time on or after the date of this Agreement and before the acceptance
of such Shares for payment or the payment therefor, any of the following
conditions exists (other than as a result of any action or inaction of Parent or
any of its subsidiaries that constitutes a breach of this Agreement):

                  (a) there shall be instituted or pending by any person or
         Governmental Entity any suit, action or proceeding (i) challenging the
         acquisition by Parent or Sub of any Shares under the Offer or pursuant
         to the Stockholder Agreement, seeking to restrain or prohibit the
         making or consummation of the Offer or the Merger or the performance of
         any of the other transactions contemplated by this Agreement or the
         Stockholder Agreement (including the voting provision thereunder), or
         seeking to obtain from the Company, Parent or Sub any damages in
         connection with the aforesaid transactions that are material in
         relation to the
<PAGE>   59
                                                                              2

         Company, (ii) seeking to prohibit or materially limit the ownership or
         operation by the Company, Parent or any of their respective
         subsidiaries of a material portion of the business or assets of the
         Company or Parent and its subsidiaries, taken as a whole, or to compel
         the Company or Parent to dispose of or hold separate any material
         portion of the business or assets of the Company, or Parent and its
         subsidiaries, taken as a whole, as a result of the Offer or any of the
         other transactions contemplated by this Agreement or the Stockholder
         Agreement, (iii) seeking to impose material limitations on the ability
         of Parent or Sub to acquire or hold, or exercise full rights of
         ownership of, any Shares to be accepted for payment pursuant to the
         Offer or purchased under the Stockholder Agreement including, without
         limitation, the right to vote such Shares on all matters properly
         presented to the stockholders of the Company, (iv) seeking to prohibit
         Parent or any of its subsidiaries from effectively controlling in any
         material respect any material portion of the business or operations of
         the Company or (v) which otherwise is reasonably likely to have a
         material adverse effect on the Company;

                  (b) there shall be any statute, rule, regulation, judgment,
         order or injunction enacted, entered, enforced, promulgated or deemed
         applicable to the Offer or the Merger, or any other action shall be
         taken by any Governmental Entity or court, other than the application
         to the Offer or the Merger of applicable waiting periods under the HSR
         Act, that is reasonably likely to result, directly or indirectly, in
         any of the consequences referred to in clauses (i) through (v) of
         paragraph (a) above; provided, however, that each of Parent and Sub
         shall have used reasonable efforts to prevent the entry of any such
         injunction or other court order and to appeal as promptly as possible
         any injunction or other court order that may be entered;

                  (c) there shall have occurred any material adverse change with
         respect to the Company;

                  (d) any of the representations and warranties of the Company
         set forth in this Agreement (without giving effect to any materiality
         or similar qualifications contained therein) shall not be true and
         correct at the date of this Agreement and at the scheduled or extended
         expiration of the Offer except (i) for changes
<PAGE>   60

                                                                              3


         specifically permitted by the Agreement and (ii) in any case where such
         failing to be true and correct could not, in the aggregate, be
         reasonably expected to have a material adverse effect on the Company;

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

                  (f) this Agreement shall have been terminated in accordance 
         with its terms;

which, in the judgment of Sub in any such case, and regardless of the
circumstances (including any action or omission by Sub) giving rise to any such
condition, makes it inadvisable to proceed with such acceptance for payment or
payments.

                  The foregoing conditions in paragraphs (a) through (f) are for
the sole benefit of Sub and Parent and may, subject to the terms of this
Agreement, be waived by Sub and Parent in whole or in part at any time and from
time to time in their sole discretion. The failure by Parent or Sub at any time
to exercise any of the foregoing rights shall not be deemed a waiver of any such
right, the waiver of any such right with respect to particular facts and
circumstances shall not be deemed a waiver with respect to any other facts and
circumstances and each such right shall be deemed an ongoing right that may be
asserted at any time and from time to time.

                                                                  EXECUTION COPY


                                    STOCKHOLDER AGREEMENT dated as of February
                           10, 1997, among JOHNSON & JOHNSON, a New Jersey
                           corporation ("Parent"), INO ACQUISITION CORP., a
                           Delaware corporation and a wholly owned subsidiary of
                           Parent ("Sub") and the individuals and other parties
                           listed on Schedule A attached hereto (each, a
                           "Stockholder" and, collectively, the "Stockholders").

                  WHEREAS Parent, Sub 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 (i) 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 Sub for all the outstanding shares
of common stock, par value $0.001 per share, of the Company ("Company Common
Stock") and (ii) for the merger of Sub with and into the Company (the "Merger"),
upon the terms and subject to the conditions set forth in the Merger Agreement;
and

                  WHEREAS each Stockholder owns the number of shares of Company
Common Stock set forth opposite his or its name on Schedule A attached hereto
(such shares of Company Common Stock, together with any other shares of capital
stock of the Company acquired by such Stockholders after the date hereof and
during the term of this Agreement (including, without limitation, through the
exercise of any stock options, warrants or similar instruments), being
collectively referred to herein as the "Subject Shares"); and

                  WHEREAS, as a condition to its willingness to enter into the
Merger Agreement, Parent has requested that each Stockholder enter into this
Agreement;

                  NOW, THEREFORE, to induce Parent to enter into, and in
consideration of its entering into, the Merger Agreement, and in consideration
of the premises and the
<PAGE>   2
representations, warranties and agreements contained herein, the parties agree
as follows:

                  1. Representations and Warranties of each Stockholder. Each
Stockholder hereby, severally and not jointly, represents and warrants to Parent
as of the date hereof in respect of himself or itself as follows:

                  (a) Authority. The Stockholder has all requisite power and
         authority to enter into this Agreement and to consummate the
         transactions contemplated hereby. This Agreement has been duly
         authorized, executed and delivered by the Stockholder and constitutes a
         valid and binding obligation of the Stockholder enforceable against
         such Stockholder in accordance with its terms (subject, as to
         enforcement of remedies, to applicable bankruptcy, reorganization,
         insolvency, moratorium or other laws affecting creditors' rights
         generally from time to time in effect and to general principles of
         equity). Except for the expiration or termination of the waiting
         periods under the HSR Act, informational filings with the SEC and the
         existence of the pledge agreement described in Exhibit I hereto (the
         "Pledge Agreement"), the execution and delivery of this Agreement do
         not, and the consummation of the transactions contemplated hereby and
         compliance with the terms hereof will not, (i) conflict with, or result
         in any violation of, or default (with or without notice or lapse of
         time or both) under any provision of, any trust agreement, loan or
         credit agreement, note, bond, mortgage, indenture, lease or other
         agreement, instrument, permit, concession, franchise, license,
         judgment, order, notice, decree, statute, law, ordinance, rule or
         regulation applicable to the Stockholder or to the Stockholder's
         property or assets, (ii) require any filing with, or permit,
         authorization, consent or approval of, any federal, state or local
         government or any court, tribunal, administrative agency or commission
         or other governmental or regulatory authority or agency, domestic,
         foreign or supranational, or (iii) violate any order, writ, injunction,
         decree, statute, rule or regulation applicable to the Stockholder or
         any of the Stockholder's properties or assets, including the Subject
         Shares. If the Stockholder is a natural person and is married, and the
         Stockholder's Subject Shares constitute community property or otherwise
         need spousal or other approval for this Agreement to be legal, valid
<PAGE>   3
         and binding, this Agreement has been duly authorized, executed and
         delivered by, and constitutes a valid and binding agreement of, the
         Stockholder's spouse, enforceable against such spouse in accordance
         with its terms (subject, as to enforcement of remedies, to applicable
         bankruptcy, reorganization, insolvency, moratorium or other laws
         affecting creditors' rights generally from time to time in effect and
         to general principles of equity). No trust of which such Stockholder is
         a trustee requires the consent of any beneficiary to the execution and
         delivery of this Agreement or to the consummation of the transactions
         contemplated hereby.

                  (b) The Subject Shares. Except with respect to Shares subject
         to the Pledge Agreement, the Stockholder is the record and beneficial
         owner of, or is trustee of a trust that is the record holder of, and
         whose beneficiaries are the beneficial owners of, and has good and
         marketable title to, the Subject Shares set forth opposite his or its
         name on Schedule A attached hereto, free and clear of any claims,
         liens, encumbrances and security interests whatsoever. The Stockholder
         does not own, of record or beneficially, any shares of capital stock of
         the Company other than the Subject Shares set forth opposite his or its
         name on Schedule A attached hereto. The Stockholder has the sole right
         to vote such Subject Shares, and none of such Subject Shares is subject
         to any voting trust or other agreement, arrangement or restriction with
         respect to the voting of such Subject Shares, except as contemplated by
         this Agreement.

                  2. Purchase and Sale of Shares. Each Stockholder hereby
severally agrees to sell to Sub, and Sub hereby agrees to purchase, all Subject
Shares set forth opposite such Stockholder's name on Schedule A hereto, at a
price per Share equal to $13.75 per Share; provided that such obligation to sell
and such obligation to purchase are subject to Sub having accepted Shares for
payment under the Offer and subject to the Minimum Condition having been
satisfied. Such Stockholder may tender such Subject Shares into the Offer and
Sub may direct that such Stockholder tender such Subject Shares and not withdraw
any Subject Shares so tendered. Any Subject Shares not purchased in the Offer
will be purchased at the same time as payment is made under the Offer.
<PAGE>   4
                  3. Representation and Warranty of Parent and Sub. Parent and
Sub each hereby represents and warrants to each Stockholder that each of them
has all requisite corporate power and authority to execute and deliver this
Agreement and to consummate the transactions contemplated hereby. The execution,
delivery and performance of this Agreement by each of Parent and Sub, and the
consummation of the transactions contemplated hereby, have been duly authorized
by all necessary corporate action on the part of each of Parent and Sub. This
Agreement has been duly executed and delivered by Parent and Sub and constitutes
a valid and binding obligation of Parent and Sub enforceable against Parent and
Sub in accordance with its terms. The execution and delivery of this Agreement
do not, and the consummation of the transactions contemplated hereby and
compliance with the terms hereof will not, conflict with, or result in any
violation of, or default (with or without notice or lapse of time or both) under
any provision of, the articles of incorporation or by-laws of Parent and Sub,
note, bond, mortgage, indenture, license, lease, contract, agreement or other
instrument or obligation or any judgment, order, notice, decree, statute, law,
ordinance, rule or regulation applicable to either Parent or Sub or to Parent or
Sub's property or assets.

                  4. Covenants of Each Stockholder. Until the termination of
this Agreement in accordance with Section 10, each Stockholder, severally and
not jointly, agrees as follows:

                  (a) At any meeting of stockholders of the Company called to
         vote upon the Merger and the Merger Agreement or at any adjournment
         thereof or in any other circumstances upon which a vote, consent or
         other approval (including by written consent) with respect to the
         Merger and the Merger Agreement is sought, the Stockholder shall vote
         (or cause to be voted) the Subject Shares in favor of the Merger, the
         adoption by the Company of the Merger Agreement and the approval of the
         terms thereof and each of the other transactions contemplated by the
         Merger Agreement.

                  (b) At any meeting of stockholders of the Company or at any
         adjournment thereof or in any other circumstances upon which the
         Stockholder's vote, consent or other approval is sought, the
         Stockholder shall vote (or cause to be voted) the Subject Shares (and
         each class thereof) against (i) any Takeover
<PAGE>   5
         Proposal as such term is defined in Section 6.02(a) of the Merger
         Agreement or (ii) any amendment of the Company's certificate of
         incorporation or by-laws or other proposal or transaction involving the
         Company, which amendment or other proposal or transaction would be
         reasonably likely to impede, frustrate, prevent or nullify the Merger,
         the Merger Agreement or any of the other transactions contemplated by
         the Merger Agreement or change in any manner the voting rights of each
         class of Company Common Stock. Subject to Section 12, the Stockholder
         further agrees not to enter into any agreement inconsistent with the
         foregoing.

                  (c) The Stockholder shall not, prior to the earliest of (A)
         the Effective Time and (B) the termination of the Merger Agreement in
         accordance with its terms, (i) sell, transfer, give, pledge, assign or
         otherwise dispose of (including by gift) (collectively, "Transfer"),
         consent to any transfer of, any or all of such Subject Shares or any
         interest therein or enter into any contract, option or other
         arrangement (including any profit sharing arrangement) with respect to
         the Transfer of, the Subject Shares to any person other than pursuant
         to the terms of the Offer or the Merger or (ii) enter into any voting
         arrangement, whether by proxy, voting agreement or otherwise, in
         connection with, directly or indirectly, any Takeover Proposal and
         agrees not to commit or agree to take any of the foregoing actions.

                  (d) Subject to the terms of Section 12, during the term of
         this Agreement, the Stockholder shall not, nor shall it permit any
         investment banker or attorney retained by, or any other adviser or
         representative of, such Stockholder to, (i) directly or indirectly
         solicit, initiate or encourage the submission of, any Takeover Proposal
         or (ii) directly or indirectly participate in any discussions or
         negotiations regarding, or furnish to any person any information with
         respect to, or take any other action to facilitate any inquiries or the
         making of any proposal that constitutes, or may reasonably be expected
         to lead to, any Takeover Proposal; provided, that it is understood that
         this clause (ii) will not be deemed to have been violated if in
         response to an unsolicited inquiry, the Stockholder states that it or
         he is subject to the provisions of this Agreement. Without limiting the
         foregoing, it is understood that any violation of the
<PAGE>   6
         restrictions set forth in the preceding sentence by an investment
         banker or attorney retained by, or other adviser or representative of,
         such Stockholder, whether or not such person is purporting to act on
         behalf of such Stockholder, shall be deemed to be a violation of this
         Section 4(d) by such Stockholder.

                  (e) Until after the Merger is consummated or the Merger
         Agreement is terminated, the Stockholder shall, at the expense of
         Parent, use all reasonable efforts to take, or cause to be taken, all
         actions, and to do, or cause to be done, and to assist and cooperate
         with the other parties in doing, all things necessary, proper or
         advisable to consummate and make effective, in the most expeditious
         manner practicable, the Merger and the other transactions contemplated
         by the Merger Agreement.

                  (f) Such Stockholder, and any beneficiary of a revocable trust
         for which such Stockholder serves as trustee, shall not take any action
         to revoke or terminate such trust or take any other action which would
         restrict, limit or frustrate in any way the transactions contemplated
         by this Agreement. Each such beneficiary hereby acknowledges and agrees
         to be bound by the terms of this Agreement applicable to it.

                  (g) (i) In the event that the Merger Agreement shall have been
         terminated under circumstances where Parent is or may become entitled
         to receive the Termination Fee, each Stockholder shall pay to Parent on
         demand an amount equal to all profit determined in accordance with
         Section 4(g)(ii) of such Stockholder from the consummation of any
         transaction which gives rise to the Company's obligation to pay the
         Termination Fee pursuant to the Merger Agreement.

                  (ii) For purposes of this Section 4(g), the profit of any
Stockholder from any Takeover Proposal shall equal (A) the aggregate
consideration that would have been received by such Stockholder pursuant to such
Takeover Proposal if such Stockholder held the same number of Subject Shares at
the consummation of such Takeover Proposal as he held at the time the Merger
Agreement was terminated (including any consideration that would have been
received in respect of any unexercised stock options or warrants or similar
instruments held at the time the Merger Agreement was terminated), valuing any
noncash consideration
<PAGE>   7
(including any residual interest in the Company) at its fair market value on the
date of such consummation less (B) the fair market value of the aggregate
consideration that would have been issuable or payable to such Stockholder
(assuming all stock options, warrants or similar instruments held by such
Stockholder were exercised) if he had received the Merger Consideration pursuant
to the Merger Agreement as originally executed (without giving effect to any
increase in such Merger Consideration).

                  (iii) In the event that (x) prior to the Effective Time, a
Takeover Proposal shall have been made and (y) the Effective Time of the Merger
shall have occurred and Parent for any reason shall have increased the amount of
Merger Consideration payable over that set forth in the Merger Agreement in
effect on the date hereof (the "Original Merger Consideration"), each
Stockholder shall pay to Parent on demand an amount in cash equal to the product
of (i) the number of Subject Shares of such Stockholder and (ii) 100% of the
excess, if any, of (A) the per share cash consideration or the per share fair
market value of any noncash consideration, as the case may be, received by the
Stockholder as a result of the Merger, as amended, determined as of the
Effective Time of the Merger, over (B) the amount of the Original Merger
Consideration determined as of the time of the first increase in the amount of
the Original Merger Consideration.

                  (iv) For purposes of this Section 4(g), the fair market value
of any noncash consideration consisting of:

                  (A)      securities listed on a national securities exchange
                           or traded on the NASDAQ/NMS shall be equal to the
                           average closing price per share of such security as
                           reported on such exchange or NASDAQ/NMS for the
                           twenty trading days prior to the date of
                           determination; and

                  (B)      consideration which is other than cash or
                           securities of the form specified in clause
                           (A) of this Section 4(g)(iv) shall be
                           determined by a nationally recognized
                           independent investment banking firm mutually
                           agreed upon by the parties within 10 business
                           days of the event requiring selection of such
                           banking firm; provided, however, that if the
                           parties are unable to agree within two
                           business days after the date of such event as
<PAGE>   8
                           to the investment banking firm, then the parties
                           shall each select one firm, and those firms shall
                           select a third investment banking firm, which third
                           firm shall make such determination; provided further,
                           that the fees and expenses of such investment banking
                           firm shall be borne by Parent. The determination of
                           the investment banking firm shall be binding upon the
                           parties.

                  (v) Any payment of profit under this Section 4(g) shall (x) if
paid in cash, be paid by wire transfer of same day funds to an account
designated by Parent and (y) if paid through a transfer of securities (with the
method and timing of such transfer to be mutually agreed), be paid as soon as
practicable through delivery of such securities, suitably endorsed for transfer;
provided that the Stockholder shall be required to pay cash under this Section
4(g) only to the extent the fair market value of the securities transferred
pursuant to clause (y) is less than such Stockholders' profit.

                  5. Covenant of Ronald Blum. Ronald Blum shall have his Shares
released from the pledge pursuant to the Pledge Agreement as soon as practicable
after the date hereof but in any event within ten business days after the date
hereof.

                  6. Grant of Irrevocable Proxy; Appointment of Proxy. (a) Each
Stockholder hereby irrevocably grants to, and appoints, Parent and James R.
Utaski and James R. Hilton, in their respective capacities as officers of
Parent, and any individual who shall hereafter succeed to any such office of
Parent, and each of them individually, such Stockholder's proxy and
attorney-in-fact (with full power of substitution), for and in the name, place
and stead of such Stockholder, to vote such Stockholder's Subject Shares, or
grant a consent or approval in respect of such Subject Shares against (i) any
Takeover Proposal or (ii) any amendment of the Company's Articles of
Incorporation or By-laws, or other proposal or transaction (including any
consent solicitation to remove or elect any directors of the Company) involving
the Company which amendment or other proposal or transaction would be reasonably
likely to impede, frustrate, prevent or nullify, or result in a breach of any
covenant, representation or warranty or any other obligation or agreement of the
Company under or with respect to, the Offer, the Merger, the Merger Agreement or
any of
<PAGE>   9
the other transactions contemplated by the Merger Agreement.

                  (b) Such Stockholder represents that any proxies heretofore
given in respect of such Stockholder's Shares are not irrevocable, and that any
such proxies are hereby revoked.

                  (c) Such Stockholder hereby affirms that the irrevocable proxy
set forth in this Section 6 is given in connection with the execution of the
Merger Agreement, and that such irrevocable proxy is given to secure the
performance of the duties of the Stockholder under this Agreement. Such
Stockholder hereby further affirms that the irrevocable proxy is coupled with an
interest and may under no circumstances be revoked. Such Stockholder hereby
ratifies and confirms all that such irrevocable proxy may lawfully do or cause
to be done by virtue hereof. Such irrevocable proxy is executed and intended to
be irrevocable in accordance with the provisions of Section 212(e) of the
Delaware General Corporation Law (the "DGCL").

                  7. Further Assurances. Each Stockholder will, at Parent's
expense, from time to time, execute and deliver, or cause to be executed and
delivered, such additional or further consents, documents and other instruments
as Parent may reasonably request for the purpose of effectively carrying out the
transactions contemplated by this Agreement.

                  8. Certain Events. (a) Each Stockholder agrees that this
Agreement and the obligations hereunder shall attach to such Stockholder's
Subject Shares and shall be binding upon any person or entity to which legal or
beneficial ownership of such Subject Shares shall pass, whether by operation of
law or otherwise, including without limitation such Stockholder's heirs,
guardians, administrators or successors. In the event of any stock split, stock
dividend, merger, reorganization, recapitalization or other change in the
capital structure of the Company affecting the Company Common Stock, or the
acquisition of additional shares of Company Common Stock or other voting
securities of the Company by any Stockholder, the number of Subject Shares
listed in Schedule A beside the name of such Stockholder shall be adjusted
appropriately and this Agreement and the obligations hereunder shall attach to
any additional shares of Company Common Stock or other
<PAGE>   10
voting securities of the Company issued to or acquired by such Stockholder.

                  (b) Each Stockholder agrees that such Stockholder will tender
to the Company, within 10 business days after the date hereof (or, in the event
Subject Shares are acquired subsequent to the date hereof within 10 business
days after the date of such acquisition), any and all certificates representing
such Stockholder's Subject Shares in order that the Company may inscribe upon
such certificates the legend in accordance with Section 7.10 of the Merger
Agreement.

                  9. Assignment. Neither this Agreement nor any of the rights,
interests or obligations hereunder shall be assigned by any of the parties
without the prior written consent of the other parties, except that (i) Sub may
assign, in its sole discretion, any or all of its rights, interests and
obligations hereunder to any subsidiary of Parent that may be substituted for
Sub as contemplated by Section 2.01 of the Merger Agreement, and (ii) Parent may
assign, in its sole discretion, any and all of its rights, interests and
obligations hereunder to any direct or indirect wholly owned subsidiary of
Parent, provided that Parent will remain liable for its obligations hereunder in
the event of any assignment pursuant to this clause (ii). Subject to the
preceding sentence, this Agreement will be binding upon, inure to the benefit of
and be enforceable by the parties and their respective successors and assigns.

                  10. Termination. This Agreement, and all rights and
obligations of the parties hereunder, shall terminate upon the date upon which
the Merger Agreement is terminated in accordance with its terms, provided that a
Termination Fee has not become, and could not at any time in the future become,
payable under the Merger Agreement, in which case Sections 4(g), 7 (as it
relates to the other sections of this Agreement that survive such termination),
8, 9, 10, 11, 13 and 14 shall survive until such Termination Fee is paid.

                  11.  General Provisions.

                  (a) Amendments. This Agreement may not be amended except by an
         instrument in writing signed by each of the parties hereto.

                  (b) Notice. All notices and other communications hereunder
         shall be in writing and shall be deemed given
<PAGE>   11
         if delivered personally or sent by overnight courier (providing proof
         of delivery) to Parent in accordance with Section 10.02 of the Merger
         Agreement and to the Stockholders at their respective addresses set
         forth on Schedule A attached hereto (or at such other address for a
         party as shall be specified by like notice).

                  (c) Interpretation. When a reference is made in this Agreement
         to Sections, such reference shall be to a Section to this Agreement
         unless otherwise indicated. The headings contained in this Agreement
         are for reference purposes only and shall not affect in any way the
         meaning or interpretation of this Agreement. Wherever the words
         "include", "includes" or "including" are used in this Agreement, they
         shall be deemed to be followed by the words "without limitation".
         Capitalized terms used and not otherwise defined in this Agreement
         shall have the respective meanings assigned to them in the Merger
         Agreement.

                  (d) Counterparts. This Agreement may be executed in one or
         more counterparts, all of which shall be considered one and the same
         agreement, and shall become effective when one or more of the
         counterparts have been signed by each of the parties and delivered to
         the other party, it being understood that each party need not sign the
         same counterpart.

                  (e) Entire Agreement; No Third-Party Beneficiaries. This
         Agreement (including the documents and instruments referred to herein)
         (i) constitutes the entire agreement and supersedes all prior
         agreements and understandings, both written and oral, among the parties
         with respect to the subject matter hereof and (ii) is not intended to
         confer upon any person other than the parties hereto any rights or
         remedies hereunder.

                  (f) Governing Law. This Agreement shall be governed by, and
         construed in accordance with, the laws of the State of Delaware
         regardless of the laws that might otherwise govern under applicable
         principles of conflicts of law thereof.

                  (g) Voidability. If prior to the execution hereof, the Board
         of Directors of the Company shall not have duly and validly authorized
         and approved by all necessary corporate action, this Agreement, the
         Merger
<PAGE>   12
         Agreement and the transactions contemplated hereby and thereby, so that
         by the execution and delivery hereof Parent or Sub would become, or
         could reasonably be expected to become an "interested stockholder" with
         whom the Company would be prevented for any period pursuant to Section
         203 of the DGCL from engaging in any "business combination" (as such
         terms are defined in Section 203 of the DGCL), then this Agreement
         shall be void and unenforceable until such time as such authorization
         and approval shall have been duly and validly obtained.

                  12. Stockholder Capacity. No person executing this Agreement
who is or becomes during the term hereof a director or officer of the Company
makes any agreement or understanding herein in his capacity as such director or
officer. Each Stockholder signs solely in his capacity as the record holder and
beneficial owner of, or the trustee of a trust whose beneficiaries are the
beneficial owners of, such Stockholder's Subject Shares and nothing herein
(including, without limitation, the provisions of Section 4(d)) shall limit or
affect any actions taken by a Stockholder in his capacity as an officer or
director of the Company.

                  13. Enforcement. The parties agree that irreparable damage
would occur in the event that any of the provisions of this Agreement were not
performed in accordance with their specific terms or were otherwise breached. It
is accordingly agreed that the parties shall be entitled to an injunction or
injunctions to prevent breaches of this Agreement and to enforce specifically
the terms and provisions of this Agreement in any court of the United States
located in the State of Delaware or in a Delaware state court, this being in
addition to any other remedy to which they are entitled at law or in equity. In
addition, each of the parties hereto (i) consents to submit such party to the
personal jurisdiction of any Federal court located in the State of Delaware or
any Delaware state court in the event any dispute arises out of this Agreement
or any of the transactions contemplated hereby, (ii) agrees that such party will
not attempt to deny or defeat such personal jurisdiction by motion or other
request for leave from any such court, (iii) agrees that such party will not
bring any action relating to this Agreement or the transactions contemplated
hereby in any court other than a Federal court sitting in the state of Delaware
or a Delaware state court and (iv) waives any right to trial by jury with
respect to
<PAGE>   13
any claim or proceeding related to or arising out of this Agreement or any of
the transactions contemplated hereby.

                  14. Public Announcements. Each Stockholder will consult with
Parent before issuing, and provide Parent with the opportunity to review and
comment upon, any press release or other public statements with respect to the
transactions contemplated by this Agreement and the Merger Agreement, and shall
not issue any such press release or make any such public statement prior to such
consultation, except as may be required by applicable law, court process or by
obligations pursuant to any listing agreement with any national securities
exchange.
