Dear Stockholder:

    You are cordially invited to attend a Special Meeting of Stockholders, which
will be held on August 31, 2000 at 21 Hickory Drive, Waltham, Massachusetts
02451 at 10:00 a.m., local time.

    As described in the enclosed Information Statement, at the Special Meeting
you will be asked to consider and vote upon the merger of Alcon Acquisition
Corp., a wholly-owned subsidiary of Alcon Holdings Inc., with and into Summit
Autonomous Inc. (the "Company"), pursuant to an Agreement and Plan of Merger
dated as of May 26, 2000. Upon consummation of the merger, each outstanding
share of the Company's common stock (other than shares held by the Company and
its subsidiaries, Alcon Holdings Inc. and its subsidiaries and dissenting
stockholders who perfect their dissenters' rights) will be converted into the
right to receive $19.00 in cash, without interest, upon surrender of
certificates formerly representing such shares.

    The merger is the second and final step in the acquisition of the Company by
Alcon Holdings Inc. The first step was a tender offer by Alcon Acquisition Corp.
for all of the outstanding shares of the Company's common stock at a price of
$19.00 per share. Alcon Acquisition Corp. purchased 41,944,555 shares pursuant
to the tender offer and now owns approximately 88.9% of the outstanding shares
of the Company.

    The affirmative vote of holders of two-thirds of the shares of the Company's
common stock outstanding and entitled to vote at the Special Meeting is
necessary to approve the Agreement and Plan of Merger. Alcon Acquisition Corp.
owns a sufficient number of shares to assure approval of the Agreement and Plan
of Merger at the Special Meeting and will vote all of its shares in favor of the
Agreement and Plan of Merger. As a result, the affirmative vote of any other
stockholder will not be required to approve the Agreement and Plan of Merger. In
light of the foregoing, the Company has determined not to solicit proxies from
its stockholders.

    YOUR BOARD OF DIRECTORS HAS DETERMINED THAT THE TERMS OF THE MERGER ARE FAIR
TO AND IN THE BEST INTERESTS OF THE SUMMIT AUTONOMOUS STOCKHOLDERS. THE BOARD OF
DIRECTORS UNANIMOUSLY RECOMMENDS THAT SUMMIT AUTONOMOUS STOCKHOLDERS VOTE "FOR"
APPROVAL OF THE AGREEMENT AND PLAN OF MERGER.

    Among the factors considered by the Board of Directors in evaluating the
merger was the opinion dated May 26, 2000 of Chase H&Q, the Company's financial
advisor, to the effect that as of such date, the cash consideration to be
received by the stockholders of the Company pursuant to the tender offer and the
merger was fair to such stockholders from a financial point of view. The opinion
contains a description of the procedures followed, matters considered and
limitation on the review undertaken by Chase H&Q in rendering its opinion. The
written opinion of Chase H&Q is attached as Annex B to the enclosed Information
Statement and should be read carefully and in its entirety by stockholders.

    WHETHER OR NOT YOU PLAN TO ATTEND THE SPECIAL MEETING, PLEASE READ THE
ATTACHED INFORMATION STATEMENT CAREFULLY. THE COMPANY IS NOT ASKING YOU FOR A
PROXY AND YOU ARE REQUESTED NOT TO SEND A PROXY.

    Please do not send any certificates for your stock at this time. You will
receive instructions regarding the surrender of your stock certificates and
receipt of payment for your shares after the merger is effective.

                                          Sincerely,

                                          /s/ Robert J. Palmisano

                                          Robert J. Palmisano
                                          President and Chief Executive Officer

  This Information Statement is dated August 10, 2000, and is being mailed to
               Summit Autonomous stockholders on August 11, 2000.

INFORMATION STATEMENT

    This Information Statement ("Information Statement") pursuant to
Section 14(c) of the Securities Exchange Act of 1934, as amended (the "Exchange
Act"), is being furnished by Summit Autonomous Inc. (the "Company") to its
stockholders in connection with the proposed merger of Alcon Acquisition Corp.
(the "Purchaser"), a wholly-owned subsidiary of Alcon Holdings Inc. ("Parent"),
with and into the Company (the "Merger") pursuant to the Agreement and Plan of
Merger dated as of May 26, 2000 (the "Merger Agreement"). Following the
effective time (the "Effective Time") of the Merger, the Company will continue
as the surviving corporation (the "Surviving Corporation") and will be a
wholly-owned subsidiary of Parent.

    The Merger is the second and final step in the acquisition of the Company by
Parent. The first step was the tender offer by the Purchaser and Parent to
purchase all of the outstanding shares of the Company's common stock (including
the associated preferred stock purchase rights) at a purchase price of $19.00
per share, net to the seller in cash, without interest (the "Offer Price"), upon
the terms and subject to the conditions set forth in the Offer to Purchase dated
June 5, 2000 (the "Offer to Purchase") and the related Letter of Transmittal
(together with the Offer to Purchase, the "Offer").

    A copy of the Merger Agreement is attached hereto as Annex A and is
incorporated herein by reference.

SECURITIES

    The title of the class of securities to which this Information Statement
relates is the common stock, par value $0.01 per share, of the Company ("Company
Common Stock"), including the associated preferred stock purchase rights (the
"Rights") issued pursuant to the Rights Agreements dated as of March 28, 2000,
as amended from time to time (the "Rights Agreement"). As of August 10, 2000,
there were 47,166,762 shares of Company Common Stock ("Shares") outstanding, of
which 41,944,555 were owned by the Purchaser.

                     QUESTIONS AND ANSWERS ABOUT THE MERGER

WHAT WILL HAPPEN IN THE MERGER?

    Upon consummation of the Merger, the Purchaser will be merged with and into
the Company and stockholders who surrender their Share certificates, other than
the Company and its subsidiaries, Parent and its subsidiaries, the Purchaser and
dissenting stockholders who perfect their dissenters' rights, will receive a
cash payment of $19.00, without interest, for each of their Shares.

WHO WILL OWN THE COMPANY AFTER THE MERGER?

    After the Merger, Parent will own all of the outstanding shares of the
Surviving Corporation.

WHY HAS THE MERGER BEEN PROPOSED?

    The Merger is the second step in a two-part transaction, the purpose of
which is the acquisition by Parent of the entire equity interest in the Company.
The first step was a tender offer for all of the outstanding Shares, which was
consummated by the Purchaser on July 3, 2000. Pursuant to the Offer, the
Purchaser purchased 41,944,555 Shares and owns approximately 88.9% of the
outstanding Shares.

WHAT VOTE IS REQUIRED TO APPROVE THE MERGER AGREEMENT?

    Approval of the Merger Agreement requires the affirmative vote of holders of
two-thirds of the Shares outstanding and entitled to vote at the Special
Meeting. THE PURCHASER ALREADY OWNS A SUFFICIENT NUMBER OF SHARES TO ASSURE
APPROVAL OF THE MERGER AGREEMENT AND WILL VOTE ALL OF ITS SHARES IN FAVOR OF THE
MERGER AGREEMENT. AS A RESULT, NO OTHER STOCKHOLDER WILL NEED TO VOTE "FOR" THE
<PAGE>
PROPOSAL FOR THE MERGER AGREEMENT TO BE APPROVED. WE ARE NOT ASKING YOU FOR A
PROXY AND YOU ARE REQUESTED NOT TO SEND US A PROXY.

WHAT WILL I RECEIVE IN THE MERGER?

    As a stockholder of the Company, you will receive $19.00 in cash, without
interest, for each Share that you validly surrender for payment. This is the
"Merger Consideration". For example, if you own 100 Shares, upon consummation of
the Merger, you will receive $1,900.00 in cash.

ARE DISSENTERS' RIGHTS AVAILABLE?

    Yes. Under Massachusetts law, stockholders who file a written notice of
objection with the Company before the taking of the vote at the Special Meeting
and whose Shares are not voted in favor of the merger agreement will be entitled
to exercise dissenters' rights in connection with the merger. Stockholders
desiring to exercise such dissenters' rights will have the rights and duties and
must follow the procedures set forth in Sections 86 through 98 of the
Massachusetts Business Corporation Law. The full text of these sections is
attached to this Information Statement as Annex C. Stockholders who wish to
exercise dissenters' rights must carefully follow the procedures described
therein and are urged to read Annex C in its entirety.

IF THE MERGER IS CONSUMMATED, WHEN CAN I EXPECT TO RECEIVE THE MERGER
  CONSIDERATION FOR MY SHARES OF COMPANY COMMON STOCK?

    As soon as reasonably practicable after the Merger is consummated, you will
receive detailed instructions regarding the surrender of your Share
certificates. You should not send your Share certificates to the Company or
anyone else until you receive these instructions. The Purchaser will send
payment of the Merger Consideration to you as promptly as practicable following
receipt of your Share certificates and other required documents.

WHEN DO YOU EXPECT THE MERGER TO BE COMPLETED?

    We expect the Merger to be consummated as soon as reasonably practicable
after the date of the Special Meeting.

WHAT ARE THE TAX CONSEQUENCES OF THE MERGER TO ME?

    The receipt of cash in exchange for Shares in the Merger by you will be a
taxable transaction for U.S. Federal income tax purposes. To review the tax
consequences to you in greater detail, see "Certain U.S. Federal Income Tax
Consequences". Your tax consequences will depend on your personal situation. You
should consult your tax advisors for a full understanding of the tax
consequences of the Merger to you.

WHAT DO I NEED TO DO NOW?

    This Information Statement contains important information regarding the
Merger and the Merger Agreement, as well as information about the Company, the
Purchaser and Parent. It also contains important information about what the
Board of Directors of the Company (the "Board of Directors") considered in
evaluating the Offer and the Merger. If you wish to understand the Merger fully,

over time.

    The Special Meeting is being held so that stockholders of the Company may

    If the Merger Agreement is approved and the Merger becomes effective, the
Purchaser will merge with and into the Company, and the Company will become a
wholly-owned subsidiary of Parent. You will receive $19.00 in cash for each
Share that you own. The Merger Consideration will not be paid in exchange for
Shares that are held in the treasury of the Company, owned by Parent, its
subsidiaries or the Purchaser or held by dissenting stockholders who seek
appraisal of the fair value of their Shares and comply with all of the
Massachusetts law procedures set forth in Annex C.

RECORD DATE

    The close of business on August 10, 2000 is the record date for
determination of stockholders of the Company entitled to notice of the Special
Meeting and entitled to vote at the Special Meeting. On the record date, there
were 47,166,762 Shares outstanding held by approximately 1,247 holders of
record.

VOTE REQUIRED TO APPROVE THE MERGER AGREEMENT

    The holders of two-thirds of the outstanding Shares must approve the Merger
Agreement. You are entitled to one vote for each Share that you owned on the
record date. THE PURCHASER OWNS A SUFFICIENT NUMBER OF SHARES TO ASSURE APPROVAL
OF THE MERGER AGREEMENT AT THE SPECIAL MEETING AND WILL VOTE ALL OF ITS SHARES
IN FAVOR OF THE MERGER AGREEMENT. AS A RESULT, THE MERGER AGREEMENT WILL BE
APPROVED WITHOUT THE AFFIRMATIVE VOTE OF ANY OTHER STOCKHOLDER. WE ARE NOT

GENERAL

    The following summary of the Merger Agreement is qualified in its entirety
by reference to the Merger Agreement, a copy of which is attached as Annex A
hereto. You should read the Merger Agreement in its entirety if you would like a
more complete description of the matters summarized below.

    The Merger Agreement provides that, following the satisfaction or waiver of
the conditions described below under "Conditions to the Merger", the Purchaser
will be merged with and into the Company, with the Company continuing as the
Surviving Corporation.

CONVERSION OF SECURITIES

    As of the Effective Time, without any further action on the part of the
Purchaser, the Company or holders of securities of the Purchaser or the Company:

    - Each issued and outstanding share of common stock of the Purchaser will be
      converted into a number of shares of common stock of the Surviving
      Corporation equal to the number of Shares outstanding immediately prior to
      the Effective Time (excluding any Shares that are owned by any subsidiary
      of the Company or Parent other than the Purchaser) divided by 1,000,
      rounded up to the next whole share;

    - Each Share that is owned directly by the Company, Parent or the Purchaser
      will be cancelled and no consideration will be delivered for any such
      Share;

    - Each Share that is owned by any subsidiary of the Company or Parent (other
      than the Purchaser) will be converted into one share of common stock of
      the Surviving Corporation;

    - Each other Share issued and outstanding prior to the Effective Time (other
      than Shares as to which dissenters' rights have been perfected) will be
      converted into the right to receive $19.00 in cash, without interest.
      These Shares will no longer be outstanding and will automatically be
      cancelled and retired and each holder of a certificate formerly
      representing any of these Shares shall cease to have any rights except the
      right to receive the Merger Consideration, less any applicable withholding
      taxes, upon surrender of the Share certificate that formerly evidenced
      Shares; and

    - Shares of Company Common Stock as to which dissenters' rights have been
      properly perfected will be converted into the right to receive from the
      Surviving Corporation the fair value of such Shares in accordance with
      Sections 86 through 98 of the Massachusetts Business Corporation Law. In
      no event will dissenters be entitled to any on-going interest in the
      Surviving Corporation.

    As a result of the actions described above, at the Effective Time, the
Company will become a wholly-owned subsidiary of Parent.

VOTE REQUIRED TO APPROVE THE MERGER

    The Massachusetts Business Corporation Law requires, among other things,
that the adoption of the Merger Agreement must be approved by the holders of
two-thirds of the Company's outstanding voting securities. The Board of
Directors has approved the Offer, the Merger and the Merger Agreement;
consequently, the only additional action of the Company necessary to effect the
Merger is

                                       5
<PAGE>
approval of the Merger Agreement by the Company's stockholders. All Shares owned
by Parent or the Purchaser will be voted in favor of the approval of the Merger
Agreement. Because the Purchaser acquired more than two-thirds of the
outstanding Shares pursuant to the Offer, it has sufficient voting power to
effect the Merger without the affirmative vote of any other stockholder of the
Company.

RECOMMENDATIONS OF THE BOARD OF DIRECTORS

    At a meeting held on May 26, 2000, the Board of Directors (i) approved the
Merger Agreement, the Offer, the Merger and the other transactions contemplated
by the Merger Agreement, (ii) determined that the terms of the Offer, the Merger
and the other transactions contemplated by the Merger Agreement were fair to and
in the best interests of the Company and its stockholders, (iii) recommended
that the Company's stockholders accept the Offer and tender their Shares
pursuant to the Offer and (iv) recommended that the Company's stockholders
approve the Merger Agreement.

BACKGROUND OF THE MERGER

    For the purposes of this Section references to Parent include Alcon
Laboratories, Inc., Parent's principal operating subsidiary. From time to time
during 1999, officers of Parent discussed with officers of the Company potential
joint business arrangements, including a business combination.

    During the summer of 1999 the Company was approached by a third party
concerning a possible acquisition of the Company. As discussions with the third
party progressed, the Company instructed its financial advisor to identify and
contact other possible bidders. In September and October 1999, the third party
conducted due diligence and the Company's financial advisor and the third
party's financial advisor commenced discussions with respect to a possible
transaction between the parties.

    On November 4, 1999, the Company's Board of Directors met to discuss a
preliminary proposal for an acquisition of the Company by the third party. The
Board of Directors instructed the Company's financial advisor to negotiate
specific terms for a potential transaction.

    In mid November 1999, the Company's financial advisor and the third party's
financial advisor had several discussions, after which the Company's financial
advisor was advised by the third party's financial advisor that mutually
satisfactory terms between the parties would not likely be reached. The
Company's financial advisor maintained contact with the third party's financial
advisors, but ceased active negotiation.

    During such period, the Company's financial advisor had identified Parent as
a potential interested party and, on October 8, 1999, contacted Parent to
determine if it was interested in acquiring the Company. The Company's financial
advisor contacted several other parties, none of which expressed an interest in
making a bid for the Company. On November 5, 1999, Parent and the Company
entered into a confidentiality agreement covering non-public information
regarding the Company to be furnished to Parent.

    From November 1999 through March 2000, there were a number of meetings and
conversations between the managements of Parent and the Company and the
financial advisors to Parent and the Company regarding a possible acquisition of
the Company. During this period representatives of Parent conducted a due
diligence investigation of the Company and discussed their analysis of the
valuation of the Company with the Company representatives.

    On April 6, 2000, Mr. Timothy R.G. Sear, President and Chief Executive
Officer of Parent, sent a letter to Mr. Robert J. Palmisano, Chief Executive
Officer of the Company, proposing to acquire all the outstanding Shares for $15
per Share in cash, which included a draft of a proposed form of the Merger
Agreement. The letter stated that the proposal was conditioned on, among other
things, Parent's completion of certain additional due diligence.

                                       6
<PAGE>
    Shortly thereafter, the financial advisor to the Company informed the
financial advisor to Parent that Parent's proposed price was unacceptable and
that the Company would not review the draft of the proposed Merger Agreement.

    On April 13, 2000, Mr. Sear sent a letter to Mr. Palmisano expressing
disappointment in the Company's response to Parent's proposal and suggesting
that the parties meet to discuss a potential transaction between Parent and the
Company.

    On April 14, 2000, Mr. Palmisano sent a letter to Mr. Sear suggesting a
meeting in Florida to determine whether the parties could agree on a transaction
at an appropriate valuation.

    On April 19, 2000, Mr. Sear and a representative of Parent's financial
advisor met with Mr. Palmisano and a representative of the Company's financial
advisor in Miami, Florida, to discuss the potential market for the Company's
products and the valuation of the Company. During the meeting, Mr. Palmisano
indicated that the Company's Board of Directors believed the Company was worth
significantly more than $15 per Share.

    On April 28, 2000, Mr. Palmisano sent a letter to Mr. Sear providing
additional information regarding the potential market for the Company's
products.

    During April 2000, representatives of Parent had several meetings with
representatives of the Company to discuss various aspects of the Company,
including the potential market for the Company's products, the Company's
financial projections, intellectual property and microkeratome technology.

    On May 3, 2000, counsel for the Company provided to counsel for Parent their
initial comments on the draft of the proposed form of the Merger Agreement.

    On May 9, 2000, Mr. Sear sent a letter to Mr. Palmisano stating that,
following the additional due diligence by Parent, Parent was increasing its
proposed price to acquire the Company to $16.50 per Share.

    On May 11, 2000, Mr. Palmisano and Mr. Sear had a telephone conversation in
which Mr. Palmisano stated that the Board of Directors had rejected Parent's
proposal of $16.50 per Share. Mr. Palmisano stated that the Company's Board
would not accept less than $19 per Share.

    As discussions were progressing with Parent, the financial advisor to the
third party which had expressed an interest in a transaction with the Company in
the summer and fall of 1999 had maintained intermittent contact with the
Company's financial advisor. During the week of May 15, 2000, the Company's
financial advisor told the third party's financial advisor that if the third
party was interested in pursuing a transaction with the Company, it needed to
make a proposal promptly. The third party's financial advisor advised the
Company's financial advisor that it did not believe the third party would be
able to make a competitive proposal, but that it would contact the Company's
financial advisor if that was not the case. As of this date, neither the Company
nor the Company's financial advisor has been contacted by the third party or its
financial advisor.

    From May 3 through May 25, 2000, representatives of Parent and the Company,
including their financial advisors and counsel, had a number of discussions
regarding the terms of the proposed Merger Agreement.

    On May 19, 2000, the Board of Directors, the Company's financial advisor and
the Company's counsel met to discuss the status of the discussions with the
third party and with Parent. After presentations by the Company's financial
advisor and the Company's counsel, the Board of Directors discussed the terms
and conditions of the proposed Merger Agreement.

    On May 24, 2000, Parent's financial advisor contacted the Company's
financial advisor to determine whether a price of $18.50 per Share would be
acceptable. The Company's financial advisor stated that a price below $19 per
Share would not be acceptable.

                                       7
<PAGE>
    On May 25, 2000, Parent's financial advisor contacted the Company's
financial advisor to state that Parent would be willing to proceed with a
transaction at $19 per Share. Beginning in the evening of May 25, 2000, and
continuing on May 26, 2000, representatives of Parent and the Company and their
respective counsel negotiated the final terms of the Merger Agreement.

    On May 26, 2000 the Board of Directors approved the proposed Merger
Agreement and the parties executed the Merger Agreement. Parent and the Company
then issued a joint press release announcing the transaction.

    On June 5, 2000, in accordance with the Merger Agreement, the Purchaser
commenced the Offer.

    On June 9, 2000, Nestle and the Company filed, pursuant to the Merger
Agreement, a Notification and Report Form for Certain Mergers and Acquisitions,
which was required to be submitted under the Hart-Scott-Rodino Antitrust
Improvements Act of 1976, as amended (the "HSR Act"), with the Department of
Justice and the Federal Trade Commission. On June 24, 2000, the applicable
waiting period under the HSR Act expired.

    At 12:00 midnight, New York City time, on Friday, June 30, 2000, the Offer
expired. On July 3, 2000, the Purchaser accepted for payment all Shares that
were validly tendered and not withdrawn pursuant to the Offer. On July 7, 2000,
the Purchaser was informed by ChaseMellon Shareholder Services, L.L.C. that a
total of 41,944,555 Shares, representing approximately 88.9% of the outstanding
Shares, had been validly tendered and not withdrawn.

    On July 5, 2000, by written consent in lieu of a meeting of the Board of
Directors: (i) the Company accepted the resignations of the following directors:
Jeffrey A. Bernfeld, C. Glen Bradley, Richard F. Miller and John A. Norris; and
(ii) the following four designees of Parent were elected to the Board: Timothy
R. G. Sear, C. Allen Baker, Charles E. Miller, Sr., and Gerald D. Cagle.

REASONS FOR THE BOARD OF DIRECTORS' RECOMMENDATIONS; FACTORS CONSIDERED

    On May 26, 2000, the Board of Directors (all of whose members were
unaffiliated with Alcon Holdings Inc. and Alcon Acquisition Corp. on that date)
approved the Merger Agreement and the transactions contemplated thereby,
including the Offer and the Merger, and recommended that all holders of Shares
accept the Offer and tender their Shares pursuant to the Offer, approve the
Merger and approve and adopt the Merger Agreement. In taking such action, the
Board of Directors considered a number of factors including, but not limited to,
the following:

    1.  The historical market prices, price to earnings ratios and other
       multiples, recent trading activity and trading range of the Shares,
       including the fact that the Offer Price represented (i) a premium of
       approximately 49.8% over the $12.6875 closing price of the Shares on
       NASDAQ on May 25, 2000, the last full trading day prior to the
       announcement of the Offer and the Merger and (ii) a premium of
       approximately 169% over the $7.0625 closing price of the Shares on NASDAQ
       on February 28, 2000, the date in the last twelve months on which the
       Shares had their lowest closing price.

    2.  The competitive challenges associated with going forward as a "stand
       alone entity" given the entry, or likely entry, into the laser vision
       correction industry of larger ophthalmic enterprises able to sell
       refractive products with other ophthalmic products and services.

    3.  The fairness opinion of Chase H&Q delivered at the meeting of the Board
       of Directors held on May 26, 2000. The full text of the written opinion
       dated as of May 26, 2000 of Chase H&Q, which contains a description of
       the procedures followed, matters considered, assumptions made and
       limitations on the review undertaken by Chase H&Q in rendering its
       opinion, is attached as Annex B hereto. Holders of Shares are urged to
       read such opinion carefully in its entirety.

                                       8
<PAGE>
    4.  The financial condition, operating results and forecasts of the Company.

    5.  The fact that no other party had presented the Company with an
       acquisition proposal that would be more favorable to the Company and its
       stockholders than the Offer and the Merger.

    6.  The fact that the Offer and the Merger provide for a prompt cash tender
       offer for all Shares to be followed by the Merger for the same
       consideration, thereby enabling the Company's stockholders, at the
       earliest possible time, to obtain the benefits of the transaction in
       exchange for their Shares.

    7.  The fact that Parent's and the Purchaser's obligations under the Offer
       were not subject to any financing condition, and the financial strength
       of Parent.

    8.  The terms and conditions of the Merger Agreement, including the parties'
       representations, warranties and covenants, the conditions to their
       respective obligations, the limited ability of Parent and the Purchaser
       to terminate the Offer or the Merger Agreement and the provision for
       payment of all cash with no financing condition.

    9.  The extensive arms-length negotiations between the Company and Parent
       that resulted in the $19.00 per Share price.

    10. The Merger Agreement permitted the Board of Directors, prior to the
       acceptance for payment of Shares pursuant to the Offer, in order to
       comply with its fiduciary duties, to furnish information and enter into
       discussions and negotiations, in connection with an unsolicited
       acquisition proposal that was reasonably likely to result in a superior
       proposal and to withdraw its recommendation of the Merger in favor of a
       superior unsolicited acquisition proposal.

    11. The Merger Agreement permitted the Board of Directors, prior to the
       acceptance for payment of Shares pursuant to the Offer, in the exercise
       of its fiduciary duties, to terminate the Merger Agreement in favor of a
       superior acquisition proposal, provided, that prior to such termination,
       the Company must have paid Parent a fee of $32.5 million.

    The foregoing discussion of information and factors considered and given
weight by the Board of Directors is not intended to be exhaustive, but is
believed to include all of the material factors, both positive and negative,
considered by the Board of Directors. In view of the variety of factors
considered in connection with its evaluation of the Offer and the Merger, the
Board of Directors did not find it practicable to, and did not, quantify or
otherwise assign relative weights to the specific factors considered in reaching
its determinations and recommendations. In addition, individual members of the
Board of Directors may have given different weights to different factors.

OPINION OF CHASE H&Q

    At the May 26, 2000 meeting of the Board of Directors, Chase H&Q delivered
its oral opinion, subsequently confirmed in writing in an opinion dated May 26,
2000, to the Board of Directors, to the effect that, as of that date and based
upon the assumptions made, matters considered and limits of review set forth in
its opinion, the consideration of $19.00 per share in cash to be received by the
Company's stockholders in the Offer and the Merger was fair to such stockholders
from a financial point of view.

                                       9
<PAGE>
    The full text of Chase H&Q's written opinion dated May 26, 2000, which sets
forth the assumptions made, matters considered and certain limitations on the
scope of review undertaken by Chase H&Q, is attached as Annex B to this
Information Statement. Stockholders are urged to read this opinion in its
entirety. Chase H&Q's opinion was provided for the use and benefit of the Board
of Directors in its evaluation of the Offer and the Merger, was directed only to
the fairness to the Company's stockholders of the consideration to be received
in the Offer and the Merger from a financial point of view, and does not
constitute a recommendation as to how any stockholder should vote with respect
to the Merger or any other matters relating to the Merger. This summary of Chase
H&Q's opinion is qualified in its entirety by reference to the full text of its
opinion, which is attached to this Information Statement as Annex B.

    In arriving at its opinion, Chase H&Q, among other things:

    - reviewed the Merger Agreement;

    - reviewed certain publicly available business and financial information
      Chase H&Q deemed relevant relating to the Company and the industries in
      which it operates;

    - reviewed certain internal non-public financial and operating data and
      forecasts provided to Chase H&Q by the management of the Company relating
      to its business;

    - discussed, with members of the senior management of the Company, the
      Company's operations, historical financial statements and future
      prospects;

    - compared the financial and operating performance of the Company with
      publicly available information concerning certain other companies Chase
      H&Q deemed comparable and reviewed the relevant historical stock prices of
      the Company Common Stock and certain publicly traded securities of such
      other companies;

    - compared the proposed financial terms of the Merger with the financial
      terms of certain other transactions Chase H&Q deemed relevant; and

    - made such other analyses and examinations as Chase H&Q deemed necessary or
      appropriate.

    In rendering its opinion, Chase H&Q assumed and relied upon, without
assuming any responsibility for verification, the accuracy and completeness of
all of the financial and other information provided to, discussed with or
reviewed by or for Chase H&Q, or publicly available, for purposes of its
opinion, and further relied upon the assurance of the management of the Company
that they were not aware of any facts that would make such information
inaccurate or misleading. Chase H&Q neither made nor obtained any independent
evaluations or appraisals of the assets or liabilities of the Company, nor did
Chase H&Q conduct a physical inspection of the properties or facilities of the
Company. Chase H&Q assumed that the financial forecasts provided to or discussed
with Chase H&Q by the Company had been reasonably determined on bases reflecting
the best currently available estimates and judgments of the management of the
Company as to the future financial performance of the Company. Chase H&Q
expressed no view as to such forecast or projection information or the
assumptions on which they were based.

    For purposes of rendering its opinion, Chase H&Q assumed that, in all
respects material to its analysis, the representations and warranties of each
party contained in the Merger Agreement were true and correct, that each party
would perform all of the covenants and agreements required to be performed by it
under the Merger Agreement and that all conditions to the consummation of the
Offer and the Merger would be satisfied without waiver thereof. Chase H&Q also
assumed that the definitive Merger Agreement would not differ in any material
respects from the draft thereof furnished to Chase H&Q.

    Chase H&Q's opinion was necessarily based on market, economic and other
conditions as they existed and could be evaluated on the date of its opinion.
Chase H&Q's opinion was limited to the

                                       10
<PAGE>
fairness, from a financial point of view, to the Company's stockholders of the
consideration to be received in the Offer and the Merger, and Chase H&Q
expressed no opinion as to the merits of the underlying decision by the Company
to engage in the Merger.

    The following is a summary of certain financial and comparative analyses
performed by Chase H&Q in arriving at its opinion. Some of these summaries of
financial analyses include information presented in tabular format. In order to
understand fully the financial analyses used by Chase H&Q, the tables must be
read together with the text of each summary. The tables alone do not constitute
a complete description of the financial analyses.

    COMPARABLE PUBLIC COMPANIES ANALYSIS.  Using publicly available information,
Chase H&Q compared certain financial and operating information and ratios for
the Company with corresponding financial and operating information and ratios
for the following two groups of companies in lines of business believed to be
generally comparable to those of the Company, as follows:

    Group One

    - Allergan, Inc.

    - Bausch & Lomb Incorporated

    - VISX, Incorporated

    - The Cooper Companies, Inc.

    - Sunrise Technologies International, Inc.

    - STAAR Surgical Company

    - KeraVision, Inc.

    - LaserSight Incorporated

    Group Two

    - Medtronic, Inc.

    - Baxter International Inc.

    - Guidant Corporation

    - Boston Scientific Corporation

    - St. Jude Medical, Inc.

    - ArthroCare Corporation

    - Novoste Corporation

    - Eclipse Surgical Technologies, Inc.

    The analysis for Group One indicated that:

    - the ratio of the total enterprise value, meaning the market value of
      equity plus total debt, minority interest and preferred stock minus cash,
      to projected revenue ranged from approximately: 2.2x to 7.2x for 2000,
      with a mean of approximately 4.2x and a median of approximately 4.0x; and
      2.0x to 4.7x for 2001, with a mean of approximately 3.4x and a median of
      approximately 3.5x;

    - the ratio of the total enterprise value to tax effected earnings before
      interest and taxes, which is referred to as EBIT, ranged from

    - the ratio of the share price, based on the closing price per share on
      May 18, 2000, to projected earnings per share ranged from approximately:
      16.7x to 83.6x for 2000, with a mean of approximately 37.2x and a median
      of approximately 25.8x; 4.9x to 50.8x for 2001, with a mean of

      28.1x for 2002, with a mean of approximately 19.9x and a median of
      approximately 16.8x.

    The analysis for Group Two indicated that:

    - the ratio of the total enterprise value to projected revenue ranged from
      approximately: 2.8x to 12.3x for 2000, with a mean of approximately 6.4x
      and a median of approximately 4.1x; and 2.6x to 10.6x for 2001, with a

      approximately 24.6x.

    Based on these analyses, the implied equity value per Share ranged from
approximately $12.00 to $18.50.

      from approximately 1.3x to 14.9x, with a mean of approximately 4.6x and a
      median of approximately 2.5x;

    - the transaction price as a multiple of estimated one-year forward earnings
      per share ranged from approximately 8.2x to 47.2x, with a mean of
      approximately 23.8x and a median of approximately 22.1x;

    - premiums paid relative to the closing price per share one day prior to the

    Based on this analysis, the implied equity value per Share using the
transaction multiples method ranged from approximately $10.50 to $21.00, and
using the premiums paid method the implied equity value per Share ranged from

    DISCOUNTED CASH FLOW ANALYSIS.  Chase H&Q performed a discounted cash flow
analysis for the Company using financial forecasts provided by the Company to
calculate a present value of projected unlevered free cash flows for the
Company. For this analysis, Chase H&Q discounted the estimated unlevered free
cash flows using a range of discount rates from 25% to 35%. Chase H&Q added to
the present values of the cash flows the terminal value of tax-affected EBIT in
the year 2006, and discounted the terminal value using the range of discount
rates that was used to discount the unlevered free cash flows. The terminal
value was calculated using the terminal multiple method, assuming a range of
terminal multiples of one-year forward tax effected EBIT from 10.0x to 20.0x.
Based on this analysis, the implied equity value per Share ranged from
approximately $15.00 to $27.00.

    The following is a summary of valuation ranges derived from Chase H&Q's
comparable public companies analysis, precedent transactions analysis and
discounted cash flow analysis, all as described above:

    The summary set forth above does not purport to be a complete description of
the analyses performed by Chase H&Q in arriving at its opinion. Arriving at a
fairness opinion is a complex process not necessarily susceptible to partial
analysis or summary description. Chase H&Q believes that its analyses must be
considered as a whole and that selecting portions of analyses and of the factors
considered by it, without considering all such factors and analyses, could
create a misleading view of the processes underlying its opinion. Chase H&Q did
not assign relative weights to any of its analyses in preparing its opinion. The
matters considered by Chase H&Q in its analyses were based on numerous
macroeconomic, operating and financial assumptions with respect to industry
performance, general business and economic conditions and other matters, many of
which are beyond the Company's control and involve the application of complex
methodologies and educated judgment. Any estimates incorporated in the analyses
performed by Chase H&Q are not necessarily indicative of actual past or future
results or values, which may be significantly more or less favorable than such
estimates. Estimated values do not purport to be appraisals and do not
necessarily reflect the prices at which businesses or companies may be sold in
the future, and such estimates are inherently subject to uncertainty. None of
the comparable companies used in the comparable public companies analysis
described above is identical to the Company, and none of the comparable
transactions used in the comparable transactions analysis described above is
identical to the Merger. Accordingly, an analysis of publicly traded comparable
companies and transactions is not mathematical; rather it involves complex
considerations and judgments concerning differences in financial and operating
characteristics of the comparable companies and other factors that could affect
the public trading value of the comparable companies or company to which they
are being compared.

    The Board of Directors selected Chase H&Q to act as its financial advisor on
the basis of the reputation of Chase H&Q as an internationally recognized
investment banking firm with substantial expertise in transactions similar to
the Merger and because it is familiar with the Company and its business. As part
of its financial advisory business, Chase H&Q is continually engaged in the
valuation of businesses and their securities in connection with mergers and
acquisitions and valuations for estate, corporate and other purposes. Chase H&Q
has acted as financial advisor to the Board of Directors in connection with the
Merger and will receive a fee for its services, payment of a significant portion
of which was contingent upon the consummation of the Offer. In the ordinary
course of business, Chase H&Q or its affiliates may trade in the debt and equity
securities of the Company for its own account and for the accounts of its
customers and, accordingly, may at any time hold a long or short position in
such securities.

    The terms of the engagement of Chase H&Q by the Board of Directors are set
forth in a letter dated October 15, 1999. Pursuant to the terms of the letter
agreement, the Company agreed to pay Chase H&Q a fee of $650,000 in cash upon
delivery of its opinion. Upon consummation of a sale of the Company, the Company
also agreed to pay to Chase H&Q a fee in cash on closing in an amount equal to
0.45% of the aggregate consideration received by the Company's stockholders
(subject to a

                                       14
<PAGE>
minimum fee of $3,000,000), against which any fees previously paid by the
Company will be credited. The Company has also agreed to reimburse Chase H&Q for
its reasonable out-of-pocket expenses, including, without limitation, the
reasonable fees and disbursements of its counsel. In addition, the Company has
also agreed to indemnify Chase H&Q against certain liabilities and expenses
arising out of its engagement.

CERTAIN COMPANY PROJECTIONS

    During the course of discussions between representatives of Parent and the
Company, the Company provided Parent or its representatives with certain
non-public business and financial information about the Company. This
information included the following projections of total revenues, net income and
earnings per share for the Company for the years ended December 31, 2000 through
2005:

</TABLE>

    The Company does not as a matter of course make public any projections as to
future performance or earnings, and the projections set forth above are included
in this Information Statement only because this information was provided to
Parent. The projections were not prepared with a view to public disclosure or
compliance with the published guidelines of the Securities and Exchange
Commission or the guidelines established by the American Institute of Certified
Public Accountants regarding projections or forecasts. The projections do not
purport to present operations in accordance with generally accepted accounting
principles, and the Company's independent auditors have not examined or compiled
the projections and accordingly assume no responsibility for them. The Company's
internal financial forecasts (upon which the projections provided to Parent and
the Purchaser were based in part) are, in general, prepared solely for internal
use and capital budgeting and other management decisions and are subjective in
many respects and thus susceptible to interpretations and periodic revision
based on actual experience and business developments. The projections also
reflect numerous assumptions made by management of the Company, including
assumptions with respect to the market for the Company's products and services,
general business, economic, market and financial conditions and other matters,
including effective tax rates consistent with historical levels for the Company
and interest rates and the anticipated amount of borrowings by the Company, all
of which are difficult to predict, many of which are beyond the Company's
control, and none of which were subject to approval by Parent or the Purchaser.
Accordingly, there can be no assurance that the assumptions made in preparing
the projections will prove accurate. It is expected that there will be
differences between actual and projected results, and actual results may be
materially greater or less than those contained in the projections. The
inclusion of the projections herein should not be regarded as an indication that
any of Parent, the Purchaser, the Company or their respective affiliates or
representatives considered or consider the projections to be a reliable
prediction of future events, and the projections should not be relied upon as
such. None of Parent, the Purchaser, the Company or any of their respective
affiliates or representatives has made or makes any representation to any person
regarding the ultimate performance of the Company compared to the information
contained in the projections, and none of them intends to update or otherwise
revise the projections to reflect circumstances existing after the date when
made or to reflect the occurrence of future events even in the event that any or
all of the assumptions underlying the projections are shown to be in error.

CHANGE OF CONTROL

    At 12:00 midnight, New York City time, on Friday, June 30, 2000, the Offer
expired. On July 3, 2000, the Purchaser accepted for payment all Shares that
were validly tendered and not withdrawn pursuant to the Offer. On July 7, 2000,
the Purchaser was informed by ChaseMellon Shareholder Services, L.L.C. that a
total of 41,944,555 Shares had been validly tendered and not withdrawn. As a
result, the Purchaser owns approximately 88.9% of the outstanding Shares. See
also "The Merger and Related Transactions--Background of the Merger", "The
Merger and Related Transactions--Board of Directors", "The Merger and Related
Transactions--Employee Benefits", "Interests of Certain Persons in the
Merger--Stock Options" and "Interests of Certain Persons in the
Merger--Severance Agreements".

CONDITIONS TO THE MERGER

    Following the consummation of the Offer, the Merger Agreement provides that
the respective obligations of each party to effect the Merger are subject to the
satisfaction or waiver of certain remaining conditions, including the following:
(a) the Company's stockholders shall have approved the Merger by an affirmative
vote of the holders of two-thirds of the outstanding Shares (the "Company
Stockholder Approval"); (b) any consents, approvals and filings under any
foreign antitrust laws, the absence of which would prohibit the consummation of
the Merger, shall have been obtained or made; (c) no statute, rule, regulation,
executive order, decree, temporary restraining order, preliminary or permanent
injunction or other order enacted, entered, promulgated, enforced or issued by
any Governmental Entity (as defined below under "--Termination of the Merger
Agreement"), or other legal restraint or prohibition preventing the consummation
of the Merger shall be in effect; provided that each of the parties shall have
used all reasonable efforts to prevent the entry of any such injunction or other
order and to appeal as promptly as possible any such 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 adoption of the Merger Agreement by the
stockholders of the Company:

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

    (b) by either Parent or the Company:

        (i) if any Federal, state, local or foreign government or any court of
            competent jurisdiction, administrative agency or commission or other
            governmental authority or instrumentality, domestic or foreign (a
            "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,
            the Shares pursuant to the Offer or the Merger and such order,
            decree, ruling or other action shall have become final and
            nonappealable; or

        (ii) if, upon a vote at a duly held meeting to obtain the Company
             Stockholder Approval, the Company Stockholder Approval is not
             obtained; provided that Parent may not terminate the Merger
             Agreement pursuant to this termination provision if the Purchaser,
             Parent or

                                       16
<PAGE>
             any other subsidiary of Parent shall not have voted its Shares in
             favor of obtaining the Company Stockholder Approval.

TAKEOVER PROPOSALS

    The Merger Agreement provides that the Company will not, nor will it
authorize or permit any of its subsidiaries to, nor will it authorize or permit
any director, officer or employee of, or any investment banker, attorney or
other advisor or representative of, the Company or any of its subsidiaries to
(i) directly or indirectly, solicit, initiate or encourage the submission of any
Takeover Proposal (as defined below), (ii) enter into any agreement with respect
to any Takeover Proposal or (iii) 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. However, prior to July 3, 2000, the date on which the
Purchaser accepted Shares for payment pursuant to the Offer, the Merger
Agreement permitted the Board of Directors, to the extent necessary to act in a
manner consistent with its fiduciary obligations, as determined in good faith by
it after consultation with outside counsel, in response to a Takeover Proposal
that the Board of Directors determined, in good faith after consultation with
outside counsel and Chase H&Q or another nationally recognized independent
financial advisor, was reasonably likely to lead to a Superior Proposal (as
defined below), that was unsolicited and that did not otherwise result from a
breach or a deemed breach of this provision, and subject to compliance with the
certain obligations to notify Parent, (x) furnish information with respect to
the Company to the person making such Takeover Proposal (and its
representatives) pursuant to a customary confidentiality agreement; and
(y) participate in discussions or negotiations with the person making such
Takeover Proposal (and its representatives) regarding such Takeover Proposal.
The Company did not receive any Takeover Proposal from a third party prior to
consummation of the Offer.

    "Takeover Proposal" means (i) any proposal or offer for a merger,
consolidation, dissolution, recapitalization or other business combination
involving the Company or any significant subsidiary of the Company, (ii) any
proposal for the issuance by the Company of over 20% of its equity securities as
consideration for the assets or securities of another person or (iii) any
proposal or offer to acquire in any manner, directly or indirectly, over 20% of
the equity securities or consolidated total assets of the Company, in each case
other than pursuant to the Offer, the Merger and the other transactions
contemplated by the Merger Agreement.

    "Superior Proposal" means any proposal made by a third party to acquire
substantially all the equity securities or assets of the Company, pursuant to a
tender or exchange offer, a merger, a consolidation, a liquidation or
dissolution, a recapitalization or a sale of all or substantially all its
assets, (i) on terms which the Board of Directors determines in good faith to be
superior from a financial point of view to the holders of Shares to the Offer,
the Merger and the other transactions contemplated by the Merger Agreement
(after consultation with the Company's financial advisor, which shall be Chase
H&Q or another nationally recognized independent financial advisor), taking into
account all the terms and conditions of such proposal and the Merger Agreement
(including any proposal by Parent to amend the terms of the Offer, the Merger
and the transactions contemplated by the Merger Agreement) and (ii) that is
reasonably capable of being completed, taking into account all financial,
regulatory, legal and other aspects of such proposal.

    The Merger Agreement further provides that, unless the Board of Directors,
after consultation with outside counsel, determines in its good faith judgment
that it is necessary to do so to fulfill its fiduciary obligations, neither the
Board of Directors nor any committee thereof may (i) withdraw (or modify in a
manner adverse to Parent or the Purchaser) or publicly propose to withdraw (or
modify in a manner adverse to Parent or the Purchaser) the approval or
recommendation by such Board of Directors or any such committee of the Merger
Agreement, the Offer or the Merger, (ii) approve any

                                       17
<PAGE>
letter of intent, agreement in principle, acquisition agreement or similar
agreement relating to any Takeover Proposal, or (iii) approve or recommend, or
publicly propose to approve or recommend, any Takeover Proposal. However, prior
to the consummation of the Offer, the Company was permitted to take the actions
set forth in clauses (ii) or (iii) of the preceding sentence if: (i) the Board
of Directors received a Superior Proposal, (ii) in light of such Superior
Proposal the Board of Directors determined in good faith, after consultation
with outside counsel, that it was necessary to withdraw or modify its approval
or recommendation of the Merger Agreement, the Offer or the Merger in order to
act in a manner consistent with its fiduciary duty under applicable law,
(iii) the Company notified Parent in writing of the determinations described in
clause (ii) above, (iv) at least three business days following receipt by Parent
of the notice referred to in clause (iii) above, and taking into account any
revised proposal made by Parent since receipt of the notice referred to in
clause (iii) above, such Superior Proposal remained a Superior Proposal and the
Board of Directors again made the determinations referred to in clause (ii)
above, (v) the Company was in compliance with the provisions related to Takeover
Proposals referenced above (other than breaches that, individually and in the
aggregate, were not material and did not prejudice Parent's rights under the
Merger Agreement), (vi) the Company had previously paid the Termination Fee
described below, (vii) the Board of Directors concurrently approved, and the
Company concurrently entered into, a definitive agreement, providing for the
implementation of such Superior Proposal and (viii) Parent was not at such time
entitled to terminate the Merger Agreement pursuant to a Company breach or
failure to perform in any material respect any of its representations,
warranties or covenants contained in the Merger Agreement. The Company did not
receive a Superior Proposal or any other Takeover Proposal from a third party
prior to consummation of the Offer.

FEES AND EXPENSES

    The Merger Agreement provides that, except as set forth below, all fees and
expenses incurred in connection with the Merger Agreement, the Offer, the Merger
and the other transactions contemplated by the Merger Agreement shall be paid by
the party incurring such fees or expenses, whether or not the Merger is
consummated.

    The Merger Agreement would have required the Company to pay to Parent a fee
of $32.5 million (the "Termination Fee") if: (i) the Merger Agreement had been
terminated because the Offer expired without the Purchaser accepting Shares for
payment as a result of the failure of the condition set forth in paragraph (d)
of Exhibit A to the Merger Agreement; (ii) the Company had terminated the Merger
Agreement in order to enter into a definitive agreement with respect to a
Superior Proposal as described above; (iii) Parent had terminated the Merger
Agreement prior to consummation of the Offer because the Board of Directors had
withdrawn or modified its recommendation of the Offer or as a result of the
Company materially breaching its obligations described under "Takeover
Proposals"; (iv) after the date of the Merger Agreement, any person had made a
Takeover Proposal, (A) the Offer had remained open until the scheduled
expiration date immediately following the date such Takeover Proposal was made,
(B) fewer than two-thirds of the Shares outstanding on a fully diluted basis had
been tendered in the Offer by such expiration date, (C) the Merger Agreement had
been terminated under certain circumstances in which the Offer was not
consummated on or before November 26, 2000 or the Offer was not consummated as a
result of a failure of certain conditions and (D) within 12 months of such
termination the Company had entered into a definitive agreement to consummate,
or consummated, the transactions contemplated by the Takeover Proposal; or
(v) the Merger Agreement had been terminated by Parent under certain
circumstances as a result of a wilful breach by the Company and within
12 months of such termination the Company had entered into a definitive
agreement to consummate, or consummated, the transactions contemplated by a
Takeover Proposal.

    The Merger Agreement provided that, if the Company had become obligated to
pay the Termination Fee pursuant to clause (v) described above as a result of a
wilful breach by the Company, Parent would have had the right to elect not to
receive the Termination Fee and instead pursue any

                                       18
<PAGE>
and all rights, claims and causes of action it may have had with respect to such
breach under law. If Parent elected to receive the Termination Fee, and the
Company paid the Termination Fee as described above, the payment by the Company
of such fee would have been Parent's sole remedy with respect to such breach and
Parent would have been required to waive, to the fullest extent permitted by
law, any and all rights, claims and causes of action (other than claims of, or
causes of action arising from, fraud) it may have had against the Company with
respect to such breach.

BOARD OF DIRECTORS

    The Merger Agreement provided that promptly upon consummation of the Offer,
the Purchaser was entitled to designate such number of directors on the Board of
Directors as would give the Purchaser representation on the Board of Directors
equal to at least that number of directors, rounded up to the next whole number,
which is the product of (a) the total number of directors on the Board of
Directors (giving effect to the directors elected pursuant to this sentence)
multiplied by (b) the percentage that (i) such number of Shares so accepted for
payment and paid for by the Purchaser plus the number of Shares otherwise owned
by the Purchaser or any other subsidiary of Parent bears to (ii) the number of
such Shares outstanding. Until the Effective Time, the Board of Directors shall
have at least three directors who were directors on the date of the Merger
Agreement (the "Independent Directors"). The Merger Agreement provides that, if
the number of Independent Directors is reduced below three for any reason
whatsoever, any remaining Independent Directors (or Independent Director, if
there is only one remaining) will be entitled to designate persons to fill such
vacancies who will be deemed to be Independent Directors for purposes of the
Merger Agreement or, if no Independent Directors then remain, the other
directors will designate three persons to fill such vacancies who are not
officers, stockholders or affiliates of the Company, Parent or the Purchaser,
and such persons will be deemed to be Independent Directors for purposes of the
Merger Agreement.

    On July 5, 2000, by written consent in lieu of a meeting of the Board of
Directors: (i) the Company accepted the resignations of the following directors:
Jeffrey A. Bernfeld, C. Glen Bradley, Richard F. Miller and John A. Norris; and
(ii) the following four designees of Parent were elected to the Board: Timothy
R. G. Sear, C. Allen Baker, Charles E. Miller, Sr., and Gerald D. Cagle.

EMPLOYEE BENEFITS

    The Merger Agreement provides that Parent will cause the Surviving
Corporation (i) to maintain for a period of one year after the Effective Time
the Company Benefit Plans (as defined in the Merger Agreement) (other than
equity-based plans) in effect on the date of the Merger Agreement or (ii) to
provide benefits (other than equity-based plans) to each current employee of the
Company and its subsidiaries that are not materially less favorable in the
aggregate to such employees than those benefits in effect for such employees on
the date of the Merger Agreement.

    In addition, from and after July 5, 2000, the date on which the Purchaser's
designees were appointed to the Board of Directors (the "Control Date"), Parent
will cause the Company or the Surviving Corporation, as applicable, to honor in
accordance with their respective terms (as in effect on the date of the Merger
Agreement), all the Company's employment, severance and termination agreements,
plans and policies disclosed in the Company's disclosure schedule to the Merger
Agreement including any change in control provisions contained therein.

    The Merger Agreement further provides that with respect to any "employee
benefit plan", as defined in Section 3(3) of ERISA, maintained by Parent or any
of its subsidiaries (including any severance plan), for all purposes, including
determining eligibility to participate and vesting, service with the Company or
any of its subsidiaries shall be treated as service with Parent or any of its
subsidiaries; provided, that such service need not be recognized to the extent
that such recognition would result in any duplication of benefits.

                                       19

REASONABLE EFFORTS; NOTIFICATION

    The Merger Agreement provides that each of the parties shall use all
reasonable efforts to take, or cause to be taken, all reasonable actions, and to
do, or cause to be done, and to assist and cooperate with the other parties in
doing, all things reasonably 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, 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 third
parties, (iii) the defending of any lawsuits or other legal proceedings, whether
judicial or administrative, challenging the Merger Agreement or the consummation
of the transactions contemplated by the Merger Agreement, including, when
reasonable, 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 the Merger Agreement and to fully carry out the
purposes of the Merger Agreement. Nothing in the Merger Agreement is deemed to
require any party to waive any substantial rights or agree to any substantial
limitation on its operations or to dispose of any significant asset or
collection of assets.

    The Company shall give prompt notice to Parent, and Parent or the Purchaser
shall give prompt notice to the Company, of (i) any representation or warranty
made by it contained in the Merger Agreement that is 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 complied with or satisfied by
it under the Merger Agreement; provided, that no such notification shall affect
the representations, warranties, covenants or agreements of the parties or the
conditions to the obligations of the parties under the Merger Agreement.

REPRESENTATIONS AND WARRANTIES

    The Merger Agreement contains various customary representations and
warranties.

PROCEDURE FOR TERMINATION, AMENDMENT, EXTENSION OR WAIVER

    The Merger Agreement may be amended by the parties at any time, whether
before or after the Company Stockholder Approval has been obtained; provided
(i) that, after the Company Stockholder Approval has been obtained, there shall
be made no amendment that by law requires further approval by the Company's
stockholders without the further approval of such stockholders and (ii) that
after the Merger Agreement is adopted by the Company's stockholders, no such
amendment or modification shall be made that reduces the amount or changes the
form of Merger Consideration or otherwise materially and adversely affects the
rights of the Company's stockholders thereunder, without the further approval of
such stockholders. The Merger Agreement may not be amended except by an
instrument in writing signed on behalf of each of the parties thereto.

    At any time prior to the Effective Time, the parties may (a) extend the time
for the performance of any of the obligations or other acts of the other
parties, (b) waive any inaccuracies in the representations and warranties
contained in the Merger Agreement or in any document delivered pursuant thereto
or (c) waive compliance with any of the agreements or conditions contained
therein. Any agreement on the part of a party to any such extension or waiver
shall be valid only if set forth in an instrument in writing signed on behalf of
such party. The failure by any party to the Merger

                                       20
<PAGE>
Agreement to assert any of its rights under the Merger Agreement or otherwise
shall not constitute a waiver of such rights.

    A termination of the Merger Agreement, an amendment of the Merger Agreement
or an extension or waiver shall, in order to be effective, require in the case
of Parent, the Purchaser or the Company, action by its Board of Directors or the
duly authorized designee of its Board of Directors; provided, that in the case
of the Company, such action shall also require action by a majority of the
Independent Directors.

RIGHTS AGREEMENT

    The Rights Agreement was amended as of May 26, 2000, to render the Rights
inapplicable to the Offer, the Merger and the other transactions contemplated by
the Merger Agreement.

THE CONFIDENTIALITY AGREEMENT

    Alcon Laboratories, Inc., the principal operating subsidiary of Parent, and
the Company entered into a Confidentiality Agreement on November 5, 1999.
Pursuant to the Confidentiality Agreement, the Company and Alcon agreed to keep
confidential certain information provided by the Company or its representatives.
The Merger Agreement provides that certain information exchanged pursuant to the
Merger Agreement will be subject to the Confidentiality Agreement.

CERTAIN U.S. FEDERAL INCOME TAX CONSEQUENCES

    The following discussion describes the material U.S. Federal income tax
consequences of the Merger. The discussion is based upon the Internal Revenue
Code of 1986, as amended (the "Code"), existing and proposed treasury
regulations, rulings, administrative pronouncements and judicial decisions,
changes to which could materially affect the tax consequences described in this
Information Statement and could be made on a retroactive basis. This discussion
does not address all aspects of U.S. Federal income taxation that may be
important to you based on your particular circumstances and does not address any
aspect of state, local, foreign or other tax laws. This summary generally
considers only Shares that are exchanged for cash pursuant to the Merger and
that are held as capital assets (generally, assets held for investment) and may
not apply to holders who acquired Shares pursuant to the exercise of employee
stock options or other compensation arrangements with the Company, holders that
are subject to special tax treatment, holders that hold Shares as part of a
"straddle", "hedge", or "conversion transaction", or holders the functional
currency of which is not the U.S. dollar. Holders that may be subject to special
tax treatment include broker-dealers, insurance companies, tax-exempt
organizations, financial institutions, and regulated investment companies.

    CONSEQUENCES TO HOLDERS OF SHARES.  A holder of Shares will recognize gain
or loss equal to the difference between the amount of cash received in the
Merger and the holder's adjusted tax basis in the Shares exchanged therefor.
Such gain or loss will be capital gain or loss and will be long-term capital
gain or loss if at the Effective Time the holder has a holding period for the
Shares of more than one year.

    BACKUP WITHHOLDING AND INFORMATION REPORTING.  Payments of cash to a holder
surrendering Shares will be subject to information reporting and "backup"
withholding at a rate of 31% of the cash payable to the holder, unless the
holder furnishes its taxpayer identification number in the manner prescribed in
applicable treasury regulations, certifies that such number is correct,
certifies as to no loss of exemption from backup withholding and meets certain
other conditions. Any amounts withheld from payments to a holder under the
backup withholding rules generally will be allowed as a credit against the
holder's U.S. Federal income tax liability, which may entitle such holder to a
refund provided the required information is furnished to the Internal Revenue
Service.

                                       21
<PAGE>
    The preceding discussion does not purport to be a complete analysis or
discussion of all potential tax effects relevant to the Merger. Thus,
stockholders are urged to consult their own tax advisors as to the specific tax
consequences to them of the Merger, including tax return reporting requirements,
the applicability and effect of Federal, state, local, foreign and other
applicable tax laws and the effect of any proposed changes in the tax laws.

METHOD OF ACCOUNTING

    The Merger will be accounted for under the purchase method of accounting.

REGULATORY AND OTHER APPROVALS

    There are no U.S. Federal or state regulatory requirements which remain to
be complied with in order to consummate the Merger (other than the filing of
articles of merger with the Secretary of State of The Commonwealth of
Massachusetts).

SOURCE AND AMOUNT OF FUNDS

    The total amount of funds required by the Purchaser to purchase all Shares
tendered pursuant to and to pay all related fees and expenses in connection with
the Offer was approximately $797 million. The amount of funds required by the
Company to make all payments to participants in the Company's stock option plans
pursuant to the Merger Agreement was approximately $39 million. The total amount
of funds required by the Purchaser to consummate and to pay all related fees and
expenses in connection with the Merger is estimated to be approximately
$104 million. The Purchaser plans to obtain all funds needed for the Merger
through capital contributions or intercompany advances from Parent. Such funds
will be made available to Parent through intercompany advances from Nestle or an
affiliate of Nestle.

                               DISSENTERS' RIGHTS

    Stockholders of the Company who do not vote in favor of adoption of the
Merger Agreement have the right to seek payment in cash of the fair value of
their Shares by complying with Sections 86 to 98, inclusive, of Chapter 156B of
the General Laws of Massachusetts ("Sections 86-98").

    The following discussion is not a complete statement of the law pertaining
to appraisal rights under Massachusetts law, and is qualified in its entirety by
the full text of Sections 86-98, which are provided in their entirety as Annex C
to this Information Statement.

    If the Merger Agreement is approved by the stockholders at the Special
Meeting and the Merger is consummated, any stockholder (1) who files with the
Company before the taking of the vote on the approval of such action written
objection to the proposed action stating that he, she or it intends to demand
payment for such person's Shares if the action is taken and (2) whose Shares are
not voted in favor of the Merger Agreement, has or may have the right to demand
in writing from the Company, within twenty days after the date of mailing to
such person of notice in writing that the corporate action has become effective,
payment for his, her or its Shares and an appraisal of the value thereof. The
Company and any such stockholder shall in such cases have the rights and duties
and shall follow the procedure set forth in Sections 86 to 98, inclusive, of
Chapter 156B of the General Laws of Massachusetts. FAILURE TO FOLLOW THE STEPS
REQUIRED BY SECTIONS 86 TO 98, INCLUSIVE, OF CHAPTER 156B OF THE GENERAL LAWS OF
MASSACHUSETTS FOR PERFECTING DISSENTERS' RIGHTS MAY RESULT IN THE LOSS OF SUCH
RIGHTS.

    Therefore, under Massachusetts law, a stockholder wishing to exercise his,
her or its appraisal rights (1) must not vote, or permit his, her or its shares
to be voted, in favor of adoption of the Merger Agreement, (2) must deliver to
the Company prior to the vote on the Merger Agreement at the Special

                                       22
<PAGE>
Meeting to be held on August 31, 2000, a written objection to the proposed
action stating that he, she or it intends to demand payment for his, her or its
Shares if the action is taken, and (3) within twenty days after the date of
mailing to such person of notice in writing that the Merger has become
effective, must demand in writing from the Company payment for such person's
Shares and an appraisal thereof. Within ten days after the Effective Time, the
Company will notify each stockholder who has properly filed written objection
and who did not vote, and whose shares were not voted, in favor of adoption of
the Merger Agreement that the Merger has become effective. The stockholder must
be the record holder of such Shares on the date the written objection is made
and must continue to hold such Shares of record until the Effective Time.
Accordingly, a stockholder who is the record holder of Shares on the date the
written demand for appraisal is made, but who thereafter transfers such Shares
prior to the Effective Time, will lose any right to appraisal in respect of such
Shares.

    You should consult your tax advisors with regard to the particular Federal,
state, local, foreign and other tax consequences to you of exercising your
appraisal rights under Massachusetts law.

                   INTERESTS OF CERTAIN PERSONS IN THE MERGER

    Stockholders should be aware that the executive officers and directors of
the Company have interests in the Merger that are in addition to or different
from the interests of stockholders of the Company generally. These interests are
discussed below.

STOCK OPTIONS

    The Merger Agreement provides that the Board of Directors (or, if
appropriate, any committee administering the Company Stock Plans (as defined in
the Merger Agreement)) shall adopt such resolutions or take such other actions
as are required to adjust the terms of all outstanding Company Stock Options (as
defined in the Merger Agreement) and all outstanding Company SARs (as defined in
the Merger Agreement), in each case whether vested or unvested, granted before
the date of the Merger Agreement under any Company Stock Plan to provide that
each such Company Stock Option (and any Company SAR related thereto) outstanding
immediately prior to the first acceptance for payment of Shares pursuant to the
Offer shall be canceled in exchange for a cash payment by the Company as soon as
practicable following the first acceptance for payment of Shares pursuant to the
Offer of an amount equal to (i) the excess, if any, of (x) the highest price per
Share to be paid pursuant to the Offer over (y) the exercise price per Share
subject to such Company Stock Option, multiplied by (ii) the number of Shares
issuable pursuant to the unexercised portion of such Company Stock Options.

    The Company has agreed to use its best efforts to obtain all consents of the
holders of Company Stock Options as shall be necessary to effectuate the
foregoing. At Parent's request, payment may be withheld in respect of any
Company Stock Option until all necessary consents with respect to such Company
Stock Option are obtained.

    The Merger Agreement provides that the Company Stock Plans shall terminate
as of the Effective Time, and the provisions in any other Benefit Plan (as
defined in the Merger Agreement) 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, and the Company
shall ensure that following the Effective Time no holder of a Company Stock
Option or Company SAR or any participant in any Company Stock Plan or other
Company Benefit Plan shall have any right thereunder to acquire any capital
stock of the Company or the Surviving Corporation in the Merger.

SEVERANCE AGREEMENTS

    The Board of Directors has approved severance agreements for its officers
and director-level employees. These severance arrangements become available only
in the event of a "change of control" of the Company and entitle covered
employees to continuation of salary, standard bonuses and benefits in the event
they are terminated without cause after a change of control or terminate their
employment for "good reason" after a change of control. The severance
arrangements would not apply to a termination for "cause" after a change of
control. The arrangements approved by the Board of Directors provide for salary
continuation and continuation of certain benefits for (i) three years for Robert
Palmisano, President and Chief Executive Officer of the Company, (ii) two years
for each of Randy Frey, Executive Vice President and Chief Technology Officer;
Charline Gauthier, Executive Vice President and Chief Operations Officer;
Bernard Haffey, Executive Vice President and Chief Commercial Officer; Robert
Kelly, Executive Vice President, Chief Financial Officer and Treasurer; and
James Lightman, Senior Vice President, General Counsel and Clerk and (iii) one
year for all other Vice Presidents. The severance arrangements also provide that
in the event the severance provisions are triggered, the Company will make
outplacement services available to such individuals for one year, all
outstanding options held by such individuals will become exercisable and such
individuals will be entitled to certain payments to make them whole for taxes
imposed by Section 4999 of the Internal

                                       25
<PAGE>
Revenue Code, the so-called "golden parachute" tax. Menderes Akdag, President of
Lens Express, Inc., has a severance arrangement with Lens Express, Inc. that
provides for salary continuation for two years on the same terms and under the
same circumstances as the severance arrangements set forth above, but which is
triggered upon a change of control of Lens Express, Inc. The cash severance
payable to Mr. Palmisano, assuming his employment is terminated under
circumstances entitling him to severance, would be $1,642,500 (before giving
effect to any payment for golden parachute taxes). The cash severance payable to
the following individuals, assuming such person's employment is terminated under
circumstances entitling him or her to severance (before giving effect to any
payment for golden parachute taxes), would be: Mr. Frey $667,000, Dr. Gauthier
$616,000, Mr. Haffey $616,000, Mr. Kelly $728,000 and Mr. Lightman $557,550. The
cash severance payable to Mr. Akdag, assuming his employment is terminated under
circumstances entitling him to severance, would be $667,800. Payments made under
these severance arrangements will be paid in a lump-sum cash payment within
30 days of termination, or, at the option of the employee entitled to the
severance payment, in monthly installments with interest at the rate of 7% per
annum over a period not to exceed two years.

INDEMNIFICATION AND INSURANCE

    Parent and the Purchaser have agreed in the Merger Agreement that Parent
shall, to the fullest extent permitted by law, cause the Company from and after
July 5, 2000 to honor all the Company's obligations to indemnify, defend and
hold harmless (including any obligations to advance funds for expenses) the
current and former directors and officers of the Company and its subsidiaries
against all losses, claims, damages or liabilities arising out of acts or
omissions by any such directors and officers occurring prior to the Effective
Time to the maximum extent that such obligations of the Company exist on the
date of the Merger Agreement, whether pursuant to the Company's charter, the
Company's by-laws, the Massachusetts Business Corporation Law, individual
indemnity agreements or otherwise, and such obligations shall survive the Merger
and shall continue in full force and effect in accordance with the terms of the
Company's charter, the Company's by-laws and such individual indemnity
agreements from the Effective Time until the expiration of the applicable
statute of limitations with respect to any claims against such directors or
officers arising out of such acts or omissions. In the event a current or former
director or officer of the Company or any of its subsidiaries is entitled to
indemnification, such director or officer shall be entitled to reimbursement
from the Company (from and after the Control Date) or the corporation surviving
the Merger (from and after the Effective Time) for reasonable attorney fees and
expenses incurred by such director or officer in pursuing such indemnification,
including payment of such fees and expenses by the Surviving Corporation or the
Company, as applicable, in advance of the final disposition of such action upon
receipt of an undertaking by such current or former director or officer to repay
such payment if it shall be adjudicated that such current or former director or
officer was not entitled to such payment.

    The Merger Agreement also provides that from and after the Control Date and
for a period of six years after the Effective Time, Parent shall cause to be
maintained in effect the current policies of directors' and officers' liability
insurance maintained by the Company (provided that Parent may either
(i) substitute therefor policies with reputable and financially sound carriers
or (ii) maintain self insurance or similar arrangements through a financially
sound insurance affiliate of Parent, in each case of at least the same coverage
and amounts containing terms and conditions which are no less advantageous) with
respect to claims arising from or related to facts or events which occurred at
or before the Effective Time; provided, that Parent shall not be obligated to
make annual premium payments for such insurance to the extent such premiums
exceed 200% of the annual premiums paid as of the date hereof by the Company for
such insurance (such 200% amount, the "Maximum Premium"). If such insurance
coverage cannot be obtained at all, or can only be obtained at an annual premium
in excess of the Maximum Premium, Parent shall maintain the most advantageous
policies of directors' and officers' insurance obtainable for an annual premium
equal to the Maximum Premium. In the Merger Agreement, the Company has
represented to Parent that the Maximum Premium is $400,000.

                                       26
<PAGE>
    The Company has agreed in the Merger Agreement to maintain, through the
Effective Time, the Company's existing directors' and officers' insurance in
full force and effect without reduction of coverage.

    The Merger Agreement also provides that the by-laws of the corporation
surviving the Merger shall contain the provisions that are set forth, as of the
date of the Merger Agreement, in Article VIII of the by-laws of the Company,
which provisions shall not be directly or indirectly (by amending, repealing or
otherwise modifying the Articles of Organization of the Company) amended,
repealed or otherwise modified for a period of six years from the Effective Time
in any manner that would affect adversely the rights thereunder of individuals
who at or at any time prior to the Effective Time were directors, officers,
employees or other agents of the Company. Additionally, if the corporation
surviving the Merger or any of its 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 and the continuing or
surviving entity does not assume the indemnification obligations of the
Surviving Corporation, or (ii) transfers all or substantially all of its
properties and assets to any person, then, and in each such case, proper
provision shall be made so that the successors and assigns of the corporation
surviving the merger assume, as a matter of law or otherwise, the obligations.

    Parent has agreed in the Merger Agreement to guarantee that if for any
reason the Company or the Surviving Corporation, as the case may be, shall not
meet its obligations, Parent shall meet such obligations described above in full
when and as such obligations arise.

                                 MISCELLANEOUS

OTHER MATTERS

    Management knows of no other business to be presented at the Special
Meeting.

        AGREEMENT AND PLAN OF MERGER dated as of May 26, 2000, among ALCON
    HOLDINGS INC., a Delaware corporation ("PARENT"), ALCON ACQUISITION CORP., a
    Massachusetts corporation ("SUB") and a wholly owned subsidiary of Parent,
    and SUMMIT AUTONOMOUS INC., a Massachusetts corporation (the "COMPANY")
    (formerly known as Summit Technology, Inc.).

    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 (as it may be amended from time to time as permitted under
this Agreement, the "OFFER") to purchase all the outstanding shares of common
stock, par value $0.01 per share, of the Company (the "COMPANY COMMON STOCK"),
including the associated Company Rights (as defined in Section 3.03), at a price
per share of Company Common Stock (including the associated Company Right) of
$19.00, net to the seller in cash, on the terms and subject to the conditions
set forth in this Agreement;

    WHEREAS the respective Boards of Directors of Parent, Sub and the Company
have approved the merger (the "MERGER") of Sub into the Company, or (at the
election of Parent) the Company into Sub, on the terms and subject to the
conditions set forth in this Agreement, whereby each issued share of Company
Common Stock not owned directly by Parent or the Company, other than Appraisal
Shares (as defined in Section 2.01(d)), shall be converted into the right to
receive the highest per share cash consideration paid pursuant to the Offer; 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, the parties hereto agree as follows:

                                   ARTICLE I
                            THE OFFER AND THE MERGER

    SECTION 1.01.  THE OFFER.  (a)  Subject to the conditions of this Agreement,
as promptly as practicable after the date of this Agreement (but in no event
later than five business days after the public announcement of this Agreement),
Sub shall, and Parent shall cause Sub to, commence the Offer within the meaning
of the applicable rules and regulations of the Securities and Exchange
Commission (the "SEC"). The obligation of Sub to, and of Parent to cause Sub to,
commence the Offer and accept for payment, and pay for, any shares of Company
Common Stock tendered pursuant to the Offer are subject to the conditions set
forth in Exhibit A. The initial expiration date of the Offer shall be the 20th
business day following the commencement of the Offer (determined using
Rules 14d-1(g)(3) and 14d-2 promulgated under the Securities Exchange Act of
1934, as amended (the "EXCHANGE ACT")). Sub expressly reserves the right to
waive any condition to the Offer or modify the terms of the Offer, except that,
without the consent of the Company, Sub shall not and Parent shall not permit
Sub to (i) reduce the number of shares of Company Common Stock subject to the
Offer, (ii) reduce the price per share of Company Common Stock to be paid
pursuant to the Offer, (iii) waive or change the Minimum Tender Condition (as
defined in Exhibit A), (iv) modify in any manner adverse to the holders of
Company Common Stock or add to the conditions set forth in Exhibit A,
(v) except as provided in the next sentence, extend the Offer or (vi) change the
form of consideration payable in the Offer. Notwithstanding the foregoing, Sub
may, without the consent of the Company, (A) if at the scheduled or any extended
expiration date of the Offer (whether extended pursuant to this clause (A) or
otherwise) any of the conditions to Sub's obligation to purchase shares of
Company Common Stock are not satisfied or waived, extend the Offer for such
period as Sub determines; PROVIDED that such extension shall be in increments of
not more than five business days if all of the conditions set forth in
Exhibit A other than the Minimum Tender Condition have been satisfied or waived
at such scheduled or extended expiration date, (B) extend the Offer for any
period required by any rule, regulation,
<PAGE>
interpretation or position of the SEC or the staff thereof applicable to the
Offer and (C) if at the scheduled or any extended expiration date of the Offer
less than 90% of the Fully Diluted Shares (as defined in Exhibit A) have been
validly tendered and not withdrawn in the Offer, extend the Offer for a period
of not more than ten business days in the aggregate beyond the latest expiration
date that would otherwise be permitted under clause (A) or (B) of this sentence.
In addition, Sub may make available a "subsequent offering period", in
accordance with Rule 14d-11 of the Exchange Act. In the event that the Minimum
Tender Condition has not been satisfied or waived at the scheduled expiration
date of the Offer, at the request of the Company, Sub shall, and Parent shall
cause Sub to, extend the expiration date of the Offer in such increments as Sub
may determine until the earliest to occur of (w) the satisfaction or waiver of
such condition, (x) Parent reasonably determines that such condition to the
Offer is not capable of being satisfied on or prior to the Outside Date (as
defined in Section 8.01(b)(i)), (y) the termination of this Agreement in
accordance with its terms and (z) the Outside Date. On the terms and subject to
the conditions of the Offer and this Agreement, Sub shall accept for payment and
pay for all shares of Company Common Stock validly tendered and not withdrawn
pursuant to the Offer that Sub becomes obligated to purchase 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 TO with respect to the Offer,
which shall contain an offer to purchase and a related letter of transmittal and
summary advertisement (such Schedule TO and the documents included therein
pursuant to which the Offer will be made, together with any supplements or
amendments thereto, the "OFFER DOCUMENTS"). Each of Parent, Sub and the Company
shall promptly correct any information provided by it for use in the Offer
Documents if and to the extent that such information shall have become false or
misleading in any material respect, and each of Parent and Sub shall take all
steps necessary to amend or supplement the Offer Documents and to cause the
Offer Documents as so amended or supplemented to be filed with the SEC and to be
disseminated to the Company's stockholders, in each case as and to the extent
required by applicable Federal securities laws. Parent and Sub shall give the
Company and its counsel a reasonable opportunity to review and comment on the
Offer Documents prior to their being filed with the SEC or disseminated to the
stockholders of the Company. Parent and Sub shall provide the Company and its
counsel in writing with 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 and shall provide the Company and its counsel with a
reasonable opportunity to participate in the response of Parent or Sub to such
comments.

    (c)  Prior to the expiration of the Offer, Parent shall provide or cause to
be provided to Sub on a timely basis the funds necessary to purchase any shares
of Company Common Stock that Sub becomes obligated to purchase pursuant to the
Offer.

    SECTION 1.02.  COMPANY ACTIONS.  (a)  Subject to Section 5.02(b), the
Company hereby approves of and consents to the Offer, the Merger and the other
transactions contemplated by this Agreement (collectively, the "TRANSACTIONS").

    (b)  On the date the Offer Documents are filed with the SEC, the Company
shall file with the SEC a Solicitation/Recommendation Statement on
Schedule 14D-9 with respect to the Offer, including an information statement
(such Schedule 14D-9, as amended and supplemented from time to time, the
"SCHEDULE 14D-9"), describing the recommendations referred to in
Section 3.04(b), or any permitted withdrawal or modification in accordance with
Section 5.02(b), and shall mail the Schedule 14D-9 (including in the information
statement) to the holders of Company Common Stock. Each of the Company, Parent
and Sub shall promptly correct any information provided by it for use in the
Schedule 14D-9 if and to the extent that such information shall have become
false or misleading in any material respect, and the Company shall 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

                                       2
<PAGE>
SEC and disseminated to the Company's stockholders, in each case as and to the
extent required by applicable Federal securities laws. The Company shall provide
Parent and its counsel in writing with 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, the Company shall cause its transfer
agent to furnish Sub as promptly as is reasonably practicable with mailing
labels containing the names and addresses of the record holders of Company
Common Stock 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 as Sub
may reasonably request in the Company's possession or control regarding the
beneficial owners of Company Common Stock, 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 (as defined in Section 3.05), and except for such
steps as are necessary to disseminate the Offer Documents and any other
documents necessary to consummate the Transactions, Parent and Sub shall hold in
confidence pursuant to the Confidentiality Agreement (as defined in
Section 6.02) the information contained in any such labels, listings and files,
shall use such information only for the purpose of communicating the Offer and
disseminating any other documents necessary to consummate the Offer, the Merger
and the other Transactions and, if this Agreement shall be terminated, shall,
upon request, deliver to the Company all copies of such information then in
their possession.

    SECTION 1.03.  THE MERGER.  On the terms and subject to the satisfaction or
waiver of the conditions set forth in this Agreement, and in accordance with the
Massachusetts Business Corporation Law (the "BCL"), Sub shall be merged with and
into the Company at the Effective Time (as defined in Section 1.05). At the
Effective Time, the separate corporate existence of Sub shall cease and the
Company shall continue as the surviving corporation (the "SURVIVING
CORPORATION"). The Surviving Corporation shall possess all the rights,
privileges, immunities, powers and franchises of the Company and Sub, and the
Surviving Corporation shall by operation of law become liable for all of the
debts, liabilities and duties of the Company and Sub. The name of the Surviving
Corporation shall be Summit Autonomous Inc. and the purpose thereof shall be as
set forth in Section 2 of the Articles of Organization of the Surviving
Corporation. 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; PROVIDED, HOWEVER, that the Company shall
not be deemed to have breached any of its representations, warranties or
covenants set forth in this Agreement solely by reason of such election. In such
event, the parties shall execute an appropriate amendment to this Agreement to
reflect the foregoing. At the election of Parent, any direct or indirect wholly
owned subsidiary of Parent may be substituted for Sub as a constituent
corporation in the Merger. In such event, the parties shall execute an
appropriate amendment to this Agreement in order to reflect the foregoing.

    SECTION 1.04.  CLOSING.  The closing (the "CLOSING") of the Merger shall
take place at the offices of Cravath, Swaine & Moore, 825 Eighth Avenue, New
York, New York 10019 at 10:00 a.m. on the second business day following the
satisfaction (or, to the extent permitted by Law, waiver by all parties) of the
conditions set forth in Article VII, or at such other place, time and date as
shall be agreed in writing between Parent and the Company. The date on which the
Closing occurs is referred to in this Agreement as the "CLOSING DATE".

    SECTION 1.05.  EFFECTIVE TIME.  Prior to the Closing, Parent shall prepare
and give the Company and its counsel the opportunity to review, and on the
Closing Date or as soon as practicable thereafter Parent shall file with the
Secretary of State of The Commonwealth of Massachusetts, articles of merger or
other appropriate documents (in any such case, the "ARTICLES OF MERGER")
executed in accordance with the relevant provisions of the BCL and shall make
all other filings or recordings required under the

                                       3
<PAGE>
BCL. The Merger shall become effective at such time as the Articles of Merger is
duly filed with such Secretary of State, or at such other time as Parent and the
Company shall agree and specify in the Articles of Merger (the time the Merger
becomes effective being the "EFFECTIVE TIME").

    SECTION 1.06.  EFFECTS.  The Merger shall have the effects set forth in
Section 80 of the BCL.

    SECTION 1.07.  ARTICLES OF ORGANIZATION AND BY-LAWS.  (a)  The Articles of
Organization of the Company shall be amended and restated at the Effective Time
to read in the form of Exhibit B, and, as so amended, such Articles of
Organization shall be the Articles of Organization of the Surviving Corporation
until thereafter changed or amended as provided therein or by applicable Law.

    (b)  Subject to Section 6.06, the By-laws of Sub 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 1.08.  DIRECTORS.  At the Closing, Parent shall designate the
directors of the Surviving Corporation and such directors shall hold office
until the earlier of their resignation or removal or until their respective
successors are duly elected and qualified, as the case may be.

    SECTION 1.09.  OFFICERS.  At the Closing, Parent shall designate the
officers of the Surviving Corporation and such officers shall hold office until
the earlier of their resignation or removal or until their respective successors
are duly elected or appointed and qualified, as the case may be.

                                   ARTICLE II
                       EFFECT ON THE CAPITAL STOCK OF THE
               CONSTITUENT CORPORATIONS; EXCHANGE OF CERTIFICATES

    SECTION 2.01.  EFFECT ON CAPITAL STOCK.  At the Effective Time, by virtue of
the Merger and without any action on the part of the holder of any shares of
Company Common Stock 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 a number of fully paid and
nonassessable shares of common stock, par value $0.01 per share, of the
Surviving Corporation ("SURVIVING CORPORATION COMMON STOCK") equal to (i) the
number of shares of Company Common Stock outstanding immediately prior to
Effective Time (excluding any shares of Company Common Stock that are owned by
any subsidiary of the Company or Parent other than Sub) divided by (ii) 1,000;
PROVIDED, HOWEVER, that if the aggregate number of shares of Surviving
Corporation Common Stock into which the capital stock of Sub is to be converted
pursuant to this Section 2.01(a) is not a whole number, such number shall be
rounded up to the next higher whole number.

    (b)  CANCELATION OF TREASURY STOCK AND PARENT-OWNED STOCK. Each share of
Company Common Stock that is owned directly by the Company, Parent or Sub shall
no longer be outstanding and shall automatically be canceled and retired and
shall cease to exist, and no other consideration shall be delivered or
deliverable in exchange therefor. Each share of Company Common Stock that is
owned by any subsidiary of the Company or Parent (other than Sub) shall
automatically be converted into one fully paid and nonassessable share of
Surviving Corporation Common Stock.

    (c)  CONVERSION OF COMPANY COMMON STOCK. (1) Subject to Sections 2.01(b) and
2.01(d), each issued share of Company Common Stock shall be converted into the
right to receive in cash the highest price per share of Company Common Stock
paid pursuant to the Offer.

    (2)  The cash payable upon the conversion of shares of Company Common Stock
pursuant to this Section 2.01(c) is referred to collectively as the "MERGER
CONSIDERATION". As of the Effective Time, all such shares of Company Common
Stock shall no longer be outstanding and shall automatically be

                                       4
<PAGE>
canceled and retired and shall cease to exist, and each holder of a certificate
representing any such shares of Company Common Stock shall cease to have any
rights with respect thereto, except the right to receive Merger Consideration
upon surrender of such certificate in accordance with Section 2.02, without
interest.

    (d)  APPRAISAL RIGHTS. Notwithstanding anything in this Agreement to the
contrary, shares ("APPRAISAL SHARES") of Company Common Stock that are
outstanding immediately prior to the Effective Time and that are held by any
person who is entitled to demand and properly demands appraisal of such
Appraisal Shares pursuant to, and who complies in all respects with, Sections 86
through 97 of the BCL (the "APPRAISAL PROVISIONS") shall not be converted into
Merger Consideration as provided in Section 2.01(c), but rather the holders of
Appraisal Shares shall be entitled to payment of the fair value of such
Appraisal Shares in accordance with the Appraisal Provisions; PROVIDED, HOWEVER,
that if any such holder shall fail to perfect or otherwise shall waive, withdraw
or lose the right to appraisal under the Appraisal Provisions, then the right of
such holder to be paid the fair value of such holder's Appraisal Shares shall
cease and such Appraisal Shares shall be deemed to have been converted as of the
Effective Time into, and to have become exchangeable solely for the right to
receive, Merger Consideration as provided in Section 2.01(c). The Company shall
serve prompt notice to Parent of any demands received by the Company for
appraisal of any shares of Company Common Stock, and Parent shall have the right
to participate in and direct all negotiations and proceedings with respect to
such demands. Prior to the Effective Time, the Company shall not, without the
prior written consent of Parent, make any payment with respect to, or settle or
offer to settle, any such demands, or agree to do any of the foregoing.

    SECTION 2.02.  EXCHANGE OF CERTIFICATES.  (a)  PAYING AGENT. Prior to the
Effective Time, Parent shall select a bank or trust company in the United
States, reasonably acceptable to the Company, to act as paying agent (the
"PAYING AGENT") for the payment of the Merger Consideration upon surrender of
certificates representing Company Common Stock. Parent shall take all steps
necessary to enable and cause the Surviving Corporation to provide to the Paying
Agent on a timely basis, as and when needed after the Effective Time, cash
necessary to pay for the shares of Company Common Stock converted into the right
to receive cash pursuant to Section 2.01(c) (such cash being hereinafter
referred to as the "EXCHANGE FUND"). If for any reason (including losses) the
Exchange Fund is inadequate to pay the amounts to which holders of shares of
Company Common Stock shall be entitled under this Section 2.02(a), Parent shall
take all steps necessary to enable or cause the Surviving Corporation promptly
to deposit in trust additional cash with the Paying Agent sufficient to make all
payments required under this Agreement, and Parent and the Surviving Corporation
shall in any event be liable for payment thereof. The Exchange Fund shall not be
used for any purpose except as expressly provided in this Agreement.

    (b)  EXCHANGE PROCEDURES. As soon as reasonably practicable after the
Effective Time, the Surviving Corporation shall cause the Paying Agent to mail
to each holder of record of a certificate or certificates (the "CERTIFICATES")
that immediately prior to the Effective Time represented outstanding shares of
Company Common Stock whose shares were converted into the right to receive
Merger Consideration pursuant to Section 2.01, (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 such 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 Merger Consideration. Upon surrender of a
Certificate for cancelation to the Paying Agent, together with such letter of
transmittal, duly executed, and such other documents as may reasonably be
required by the Paying Agent, the holder of such Certificate shall be entitled
to receive in exchange therefor the amount of cash into which the shares of
Company Common Stock theretofore represented by such Certificate shall have been
converted pursuant to Section 2.01, and the Certificate so surrendered shall
forthwith be canceled. In the event of a transfer of ownership of Company

                                       5
<PAGE>
Common Stock 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 Parent that such tax has been paid or is not
applicable. Until surrendered as contemplated by this Section 2.02, 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 of Company Common Stock theretofore represented
by such Certificate have been converted pursuant to Section 2.01. If any holder
of shares of Company Common Stock shall be unable to surrender such holder's
Certificates because such Certificates have been lost, mutilated or destroyed,
such holder may deliver in lieu thereof an affidavit and indemnity bond in form
and substance and with surety reasonably satisfactory to the Surviving
Corporation. No interest shall be paid or accrue on the cash payable upon
surrender of any Certificate.

    (c)  NO FURTHER OWNERSHIP RIGHTS IN COMPANY COMMON STOCK. The Merger
Consideration paid in accordance with the terms of this Article II upon
conversion of any shares of Company Common Stock shall be deemed to have been
paid in full satisfaction of all rights pertaining to such shares of Company
Common Stock, and after the Effective Time there shall be no further
registration of transfers on the stock transfer books of the Surviving
Corporation of shares of Company Common Stock that were outstanding immediately
prior to the Effective Time. If, after the Effective Time, any certificates
formerly representing shares of Company Common Stock are presented to the
Surviving Corporation or the Paying Agent for any reason, they shall be canceled
and exchanged as provided in this Article II.

    (d)  TERMINATION OF EXCHANGE FUND. Any portion of the Exchange Fund that
remains undistributed to the holders of Company Common Stock for six months
after the Effective Time shall be delivered to Parent, upon demand, and any
holder of Company Common Stock who has not theretofore complied with this
Article II shall thereafter look only to Parent for payment of its claim for
Merger Consideration.

    (e)  NO LIABILITY. None of Parent, Sub, the Company or the Paying Agent
shall be liable to any person in respect of any cash from the Exchange Fund
delivered to a public official pursuant to any applicable abandoned property,
escheat or similar Law. If any Certificate has not been surrendered prior to
five years after the Effective Time (or immediately prior to such earlier date
on which Merger Consideration in respect of such Certificate would otherwise
escheat to or become the property of any Governmental Entity (as defined in
Section 3.05)), any such shares, cash, dividends or distributions 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 interest
of any person previously entitled thereto.

    (f)  INVESTMENT OF EXCHANGE FUND. The Paying Agent shall invest any cash
included in the Exchange Fund, as directed by Parent, on a daily basis. Any
interest and other income resulting from such investments shall be paid to
Parent.

    (g)  WITHHOLDING RIGHTS. Parent shall be entitled to deduct and withhold
from the consideration otherwise payable to any holder of Company Common Stock
pursuant to this Agreement such amounts as may be required to be deducted and
withheld with respect to the making of such payment under the Code (as defined
in Section 3.11), or under any provision of state, local or foreign tax Law.

    (h)  CHARGES AND EXPENSES. The Surviving Corporation shall pay all charges
and expenses, including those of the Paying Agent, in connection with the
exchange of cash for shares of Company Common Stock.

                                  ARTICLE III
                 REPRESENTATIONS AND WARRANTIES OF THE COMPANY

    The Company represents and warrants to Parent and Sub as follows:

    SECTION 3.01.  ORGANIZATION, STANDING AND POWER.  Each of the Company and
each of its subsidiaries (the "Company Subsidiaries") is duly organized, validly
existing and in good standing under the laws of the jurisdiction in which it is
organized and has full corporate power and authority and possesses all
governmental franchises, licenses, permits, authorizations and approvals, and
has made all filings, registrations and declarations, in each case whether
domestic or foreign, necessary to enable it to own, lease or otherwise hold its
properties and assets and to conduct its businesses as presently conducted,
including all licenses, approvals and registrations by or with the U.S. Food and
Drug Administration (the "FDA"), and all other Governmental Entities performing
similar functions, necessary for the sale and distribution of its products in
all jurisdictions in which such products are sold or distributed, in each case
other than such franchises, licenses, permits, authorizations, approvals,
filings, registrations and declarations the lack of which, individually and in
the aggregate, has not had and would not reasonably be expected to have a
material adverse effect on the Company and the Company Subsidiaries, taken as a
whole, a material adverse effect on the ability of the Company to perform its
obligations under this Agreement or a material adverse effect on the ability of
the Company to consummate the Offer, the Merger and the other Transactions (a
"COMPANY MATERIAL ADVERSE EFFECT"). The Company and each Company Subsidiary is
duly qualified to do business in each jurisdiction where the nature of its
business or their ownership or leasing of its properties make such qualification
necessary except where the failure to so qualify has not had and would not
reasonably be expected to have a Company Material Adverse Effect. The Company
has made available to Parent true and complete copies of the articles of
organization of the Company, as amended to the date of this Agreement (as so
amended, the "COMPANY CHARTER"), and the by-laws of the Company, as amended to
the date of this Agreement (as so amended, the "COMPANY BY-LAWS"), and the
comparable charter and organizational documents of each Company Subsidiary, in
each case as amended through the date of this Agreement.

    SECTION 3.02.  COMPANY SUBSIDIARIES; EQUITY INTERESTS.  (a)  The letter,
dated as of the date of this Agreement, from the Company to Parent and Sub (the
"COMPANY DISCLOSURE LETTER") lists each Company Subsidiary and its jurisdiction
of organization. All the outstanding shares of capital stock of each
"significant subsidiary" (as defined in Regulation S-X of the Federal securities
laws) ("SIGNIFICANT SUBSIDIARY") of the Company have been validly issued and are
fully paid and nonassessable and, except as set forth in the Company Disclosure
Letter, are owned by the Company, by another Significant Subsidiary of the
Company or by the Company and another Significant Subsidiary of the Company,
free and clear of all pledges, liens, charges, mortgages, encumbrances and
security interests of any kind or nature whatsoever (collectively, "LIENS").

    (b)  Except for its interests in the Company Subsidiaries and except for the
ownership interests set forth in the Company Disclosure Letter, the Company does
not own, directly or indirectly, any capital stock, membership interest,
partnership interest, joint venture interest or other equity interest in any
person.

    SECTION 3.03.  CAPITAL STRUCTURE.  The authorized capital stock of the
Company consists of 100,000,000 shares of Company Common Stock and 5,000,000
shares of preferred stock, par value $0.01 per share (together with the Company
Common Stock, the "COMPANY CAPITAL STOCK"). At the close of business on May 25,
2000, (i) 46,892,798 shares of Company Common Stock were issued and outstanding,
(ii) 164,715 shares of Company Common Stock were held by the Company in its
treasury, (iii) 3,980,328 shares of Company Common Stock were subject to
outstanding Company Stock Options (as defined in Section 6.04) and 2,209,747
additional shares of Company Common Stock were reserved for issuance pursuant to
the Company Stock Plans (as defined in Section 6.04), (iv) 42,471 shares of

                                       7
<PAGE>
Company Common Stock were subject to outstanding Company Warrants (as defined
below) and (v) 100,000 shares of Series A Preferred Stock, par value $.01 per
share, of the Company were reserved for issuance in connection with the rights
(the "COMPANY RIGHTS") issued pursuant to the Rights Agreement dated as of
March 28, 2000 (as amended from time to time, the "COMPANY RIGHTS AGREEMENT"),
between the Company and Fleet National Bank, as Rights Agent. Except as set
forth above, at the close of business on May 26, 2000, no shares of capital
stock or other voting securities of the Company were issued, reserved for
issuance or outstanding. There are no outstanding Company SARs (as defined in
Section 6.04) that were not granted in tandem with a related Company Stock
Option. All outstanding shares of Company Capital Stock are, and all such shares
that may be issued prior to the Effective Time will be when issued, duly
authorized, validly issued, fully paid and nonassessable and not subject to or
issued in violation of any purchase option, call option, right of first refusal,
preemptive right, subscription right or any similar right under any provision of
the BCL, the Company Charter, the Company By-laws or any Contract (as defined in
Section 3.05) to which the Company is a party or otherwise bound. There are not
any 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 holders of Company Common Stock may vote
("VOTING COMPANY DEBT"). Except as set forth above, as of the date of this
Agreement, there are not any options, warrants, rights, convertible or
exchangeable securities, "phantom" stock rights, stock appreciation rights,
stock-based performance units, commitments, Contracts, arrangements or
undertakings of any kind to which the Company or any Company Subsidiary is a
party or by which any of them is bound (i) obligating the Company or any Company
Subsidiary to issue, deliver or sell, or cause to be issued, delivered or sold,
additional shares of capital stock or other equity interests in, or any security
convertible or exercisable for or exchangeable into any capital stock of or
other equity interest in, the Company or of any Company Subsidiary or any Voting
Company Debt, (ii) obligating the Company or any Company Subsidiary to issue,
grant, extend or enter into any such option, warrant, call, right, security,
commitment, Contract, arrangement or undertaking or (iii) that give any person
the right to receive any economic benefit or right similar to or derived from
the economic benefits and rights occurring to holders of Company Capital Stock.
As of the date of this Agreement, there are not any outstanding contractual
obligations of the Company or any Company Subsidiary to repurchase, redeem or
otherwise acquire any shares of capital stock of the Company or any Company
Subsidiary. The Company has delivered to Parent a complete and correct copy of
the Company Rights Agreement, as amended to the date of this Agreement.
"WARRANTS" means warrants to purchase Company Common Stock assumed in connection
with the Company's acquisition of Autonomous Technologies Corporation, a Florida
corporation, on April 29, 1999.

    SECTION 3.04.  AUTHORITY; EXECUTION AND DELIVERY; ENFORCEABILITY.  (a)  The
Company has all requisite corporate power and authority to execute and deliver
this Agreement and, subject to the Company Stockholder Approval (as defined
below) with respect to the Merger if required by Law, to consummate the
Transactions. The execution and delivery by the Company of this Agreement and
the consummation by the Company of the Transactions have been duly authorized by
all necessary corporate action on the part of the Company, subject, in the case
of the Merger, to receipt of the Company Stockholder Approval (as defined in
Section 3.04(c)). The Company has duly executed and delivered this Agreement,
and this Agreement constitutes its legal, valid and binding obligation (subject
to the Company Stockholder Approval with respect to the Merger if required by
Law), enforceable against it in accordance with its terms, except to the extent
that enforceability may be limited by bankruptcy, insolvency, reorganization,
moratorium, fraudulent transfer or other similar laws of general applicability
relating to or affecting the enforcement of creditors' rights and by the effect
of the principles of equity (regardless of whether enforceability is considered
in a proceeding in equity or at law).

    (b)  The Board of Directors of the Company (the "COMPANY BOARD"), at a
meeting duly called and held, duly and unanimously adopted resolutions
(i) approving this Agreement, the Offer, the

                                       8
<PAGE>
Merger and the other Transactions, (ii) determining that the terms of the Offer,
the Merger and the other Transactions are fair to and in the best interests of
the Company and its stockholders, (iii) recommending that the holders of Company
Common Stock accept the Offer and tender their shares of Company Common Stock
pursuant to the Offer and (iv) recommending that the Company's stockholders
approve this Agreement. Such resolutions are sufficient to render inapplicable
to Parent and Sub and this Agreement, the Offer, the Merger and the other
Transactions the provisions of Chapter 110C (assuming the requirement that the
terms of the Offer be furnished to shareholders is satisfied), Chapter 110D and
Chapter 110F of the BCL. To the Company's knowledge, no other state takeover
statute or similar statute or regulation applies or purports to apply to the
Company with respect to this Agreement, the Offer, the Merger or any other
Transaction. The Company has been advised by each of its directors and executive
officers that, as of the date of this Agreement, each such person intends to
tender all shares of Company Common Stock owned by such person pursuant to the
Offer, except to the extent of any restrictions created by Section 16(b) of the
Exchange Act.

    (c)  The only vote of holders of any class or series of Company Capital
Stock necessary to approve and adopt this Agreement and the Merger is the
approval of this Agreement by the holders of two-thirds of the outstanding
Company Common Stock (the "COMPANY STOCKHOLDER APPROVAL"). The affirmative vote
of the holders of Company Capital Stock, or any of them, is not necessary to
consummate the Offer or any Transaction other than the Merger.

    SECTION 3.05.  NO CONFLICTS; CONSENTS.  (a)  Except as set forth in the
Company Disclosure Letter, the execution and delivery by the Company of this
Agreement do not, and the consummation of the Offer, the Merger and the other
Transactions (other than the transactions set forth in Section 6.13) and
compliance with the terms hereof (other than Section 6.13) will not, result in
any violation of or default (with or without notice or lapse of time, or both)
under, or give rise to a right of termination, cancelation or acceleration of
any obligation or to loss of a material benefit under, or to increased,
additional, accelerated or guaranteed rights or entitlements of any person
under, or result in the creation of any Lien upon any of the properties or
assets of the Company or any Company Subsidiary under, any provision of (i) the
Company Charter, the Company By-laws or the comparable charter or organizational
documents of any Company Subsidiary, (ii) any contract, lease, license,
indenture, note, bond, agreement, permit, concession, franchise or other
instrument (a "CONTRACT") to which the Company or any Company Subsidiary is a
party or by which any of their respective properties or assets is bound or
(iii) subject to the filings and other matters referred to in Section 3.05(b),
any judgment, order, injunction or decree, domestic or foreign ("JUDGMENT"), or
statute, law (including common law), legislation, interpretation, ordinance,
rule or regulation, domestic or foreign ("LAW"), applicable to the Company or
any Company Subsidiary or their respective properties or assets, other than, in
the case of clauses (ii) and (iii) above, any such items that, individually and
in the aggregate, have not had and would not reasonably be expected to have a
Company Material Adverse Effect.

    (b)  No consent, approval, license, permit, order or authorization
("CONSENT") of, or registration, declaration or filing with, any Federal, state,
local or foreign government or any court of competent jurisdiction,
administrative agency or commission or other governmental authority or
instrumentality, domestic or foreign (a "GOVERNMENTAL ENTITY") is required to be
obtained or made by or with respect to the Company or any Company Subsidiary in
connection with the execution, delivery and performance of this Agreement or the
consummation of the Transactions (other than the transactions set forth in
Section 6.13), other than (i) compliance with and filings under the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the "HSR
ACT"), (ii) the filing with the SEC of (A) the Schedule 14D-9, (B) a proxy or
information statement relating to the approval of this Agreement by the
Company's stockholders (the "PROXY STATEMENT"), (C) any information statement
(the "INFORMATION STATEMENT") required under Rule 14f-1 in connection with the
Offer and (D) such reports under Section 13 of the Exchange Act as may be
required in connection with this Agreement, the Offer, the Merger and the other
Transactions, (iii) the filing of the Articles of Merger with the Secretary of
State

                                       9
<PAGE>
of The Commonwealth of Massachusetts and appropriate documents with the relevant
authorities of the other jurisdictions in which the Company is qualified to do
business, (iv) such filings as may be required in connection with the taxes
described in Section 6.09, (v) compliance with and filings under the Laws of the
European Union, Brazil, Germany, Ireland, Italy, the Netherlands and certain
other foreign jurisdictions, in each case if and to the extent required, and
(vi) such other items that, individually and in the aggregate, have not had and
would not reasonably be expected to have a Company Material Adverse Effect.

    (c)  The Company and the Company Board have taken all action necessary to
(i) render the Company Rights inapplicable to this Agreement, the Offer, the
Merger and the other Transactions and (ii) ensure that (A) neither Parent nor
any of its stockholders, affiliates or associates is or will become an
"Acquiring Person" (as defined in the Company Rights Agreement) by reason of
this Agreement, the Offer, the Merger or any other Transaction), (B) a
"Distribution Date" (as defined in the Company Rights Agreement) shall not occur
by reason of this Agreement, the Offer, the Merger or any other Transaction and
(C) the Company Rights shall expire immediately prior to the Effective Time.

    SECTION 3.06.  SEC DOCUMENTS; UNDISCLOSED LIABILITIES.  The Company has
filed all reports, schedules, forms, statements and other documents required to
be filed by the Company with the SEC since January 1, 1998 (the "COMPANY SEC
DOCUMENTS"). As of its respective date, each Company SEC Document complied in
all material respects with the requirements of the Exchange Act or the
Securities Act of 1933, as amended (the "Securities Act"), as the case may be,
and the rules and regulations of the SEC promulgated thereunder applicable to
such Company SEC Document, and did not contain any untrue statement of a
material fact or omit 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. As of the date of this Agreement,

May 12, 2000), and its Current Report on Form 8-K (filed on May 12, 2000)
(collectively, the "2000 SEC DOCUMENTS") taken together do 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. The
consolidated financial statements of the Company included in the Company SEC
Documents comply as to form in all material respects with applicable accounting
requirements and the published rules and regulations of the SEC with respect
thereto, have been prepared in accordance with generally accepted accounting
principles ("GAAP") (except, in the case of unaudited statements, as permitted
by Form 10-Q of the SEC) applied on a consistent basis during the periods
involved (except as may be indicated in the notes thereto) and fairly present
the consolidated financial position of the Company and its consolidated
subsidiaries as of the dates thereof and the consolidated results of their
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 Filed Company SEC Documents (as defined in Section 3.08), neither the
Company nor any Company Subsidiary has any liabilities or obligations of any
nature (whether accrued, absolute, contingent or otherwise) required by GAAP to
be set forth on a consolidated balance sheet of the Company and its consolidated
subsidiaries or in the notes thereto, other than liabilities or obligations
incurred in the ordinary course of business consistent with prior practice since
the date of the most recent financial statements included in the Filed Company
SEC Documents.

    SECTION 3.07.  INFORMATION SUPPLIED.  None of the information supplied or to
be supplied by the Company for inclusion or incorporation by reference in
(i) the Offer Documents, the Schedule 14D-9 or the Information Statement will,
at the time such document is filed with the SEC, at any time it is amended or
supplemented or at the time it is first published, sent or given to the

                                       10
<PAGE>
Company's stockholders, contain any untrue statement of a material fact or omit
to state any material fact required to be stated therein or necessary to make
the statements therein not misleading, or (ii) the Proxy Statement will, at the
date it is first mailed to the Company's stockholders or at the time of the
Company Stockholders Meeting (as defined in Section 6.01), 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 is made by
the Company with respect to statements made or incorporated by reference therein
based on information supplied by Parent or Sub for inclusion or incorporation by
reference therein.

    SECTION 3.08.  ABSENCE OF CERTAIN CHANGES OR EVENTS.  Except as disclosed in
the Company SEC Documents filed and publicly available prior to the date of this
Agreement (the "FILED COMPANY SEC DOCUMENTS") or in the Company Disclosure
Letter, from the date of the most recent audited financial statements included
in the Filed Company SEC Documents to the date of this Agreement, the Company
has conducted its business only in the ordinary course, and during such period
there has not been:

        (i)  any event, change, effect or development that, individually or in
    the aggregate, has had or would reasonably be expected to have a Company
    Material Adverse Effect;

        (ii)  any declaration, setting aside or payment of any dividend or other
    distribution (whether in cash, stock or property) with respect to any
    Company Capital Stock or any repurchase for value by the Company of any
    Company Capital Stock;

        (iii)  any split, combination or reclassification of any Company Capital
    Stock or any issuance or the authorization of any issuance of any other

    Company Capital Stock;

        (iv)  (A)  any granting by the Company or any Company Subsidiary to any
    current or former director, officer or employee of the Company or any
    Company Subsidiary of any increase in compensation, except to the extent
    required under employment agreements in effect as of the date of the most
    recent audited financial statements included in the Filed Company SEC
    Documents or, with respect to employees (other than directors, officers or
    key employees) in the ordinary course of business consistent with prior
    practice and except for Company Stock Options that are reflected as
    outstanding in clause (iii) of Section 3.03, (B) any granting by the Company
    or any Company Subsidiary to any such director, officer or employee of any
    material increase in severance or termination pay, except as was required
    under any employment, severance or termination policy, practice or
    agreements in effect as of the date of the most recent audited financial
    statements included in the Filed Company SEC Documents or (C) any entry by
    the Company or any Company Subsidiary into, or any amendment of, any
    employment, severance or termination agreement with any such director,
    officer or employee, except for such agreements or amendments with employees
    (other than directors, officers or key employees) that are entered into in
    the ordinary course of business consistent with prior practice;

        (v)  any termination of employment or departure of any officer, material
    scientist or other key employee of the Company or any Company Subsidiary;

        (vi)  any change in accounting methods, principles or practices by the
    Company or any Company Subsidiary materially affecting the consolidated
    assets, liabilities or results of operations of the Company, except insofar
    as may have been required by a change in GAAP; or

        (vii)  any material elections with respect to Taxes (as defined in
    Section 3.09) by the Company or any Company Subsidiary or settlement or
    compromise by the Company or any Company Subsidiary of any material Tax
    liability or refund.

                                       11
<PAGE>
    SECTION 3.09.  TAXES.  (a)  Each of the Company and each Company Subsidiary
has timely filed, or has caused to be timely filed on its behalf, all Tax
Returns required to be filed by it, and all such Tax Returns are true, complete
and accurate, except to the extent any failure to file or any inaccuracies in
any filed Tax Returns, individually and in the aggregate, has not had and would
not reasonably be expected to have a Company Material Adverse Effect. All Taxes
shown to be due on such Tax Returns, or otherwise owed, have been timely paid,
except to the extent that any failure to pay, individually and in the aggregate,
has not had and would not reasonably be expected to have a Company Material
Adverse Effect.

    (b)  The most recent financial statements contained in the Filed Company SEC
Documents reflect an adequate reserve (in accordance with GAAP) for all Taxes
payable by the Company and the Company Subsidiaries for all Taxable periods and
portions thereof through the date of such financial statements (in addition to
any reserve for deferred Taxes established to reflect timing differences between
book and tax income). No deficiency with respect to any Taxes has been proposed,
asserted or assessed against the Company or any Company Subsidiary, and no
requests for waivers of the time to assess any such Taxes are pending, except to
the extent any such deficiency or request for waiver, individually and in the
aggregate, has not had and would not reasonably be expected to have a Company
Material Adverse Effect.

    (c)  The Federal income Tax Returns of the Company and each Company
Subsidiary consolidated in such Returns have never been examined by or settled
with the United States Internal Revenue Service. All material assessments for
Taxes due with respect to such completed and settled examinations or any
concluded litigation have been fully paid.

    (d)  There are no material Liens for Taxes (other than for current Taxes not
yet due and payable) on the assets of the Company or any Company Subsidiary.
Neither the Company nor any Company Subsidiary is bound by any agreement with
respect to Taxes other than agreements between or among the Company and Company
Subsidiaries and no other person.

    (e)  Note 14 to the Company's consolidated financial statements included in
the 1999 Form 10-K has been prepared in accordance with GAAP.

    (f)  No claim has been made in the past five years by any authority in a
jurisdiction within which the Company or any Company Subsidiary does not file
Tax Returns that it is, or may be, subject to taxation by that jurisdiction.

    (g)  Neither the Company nor any Company Subsidiary has constituted either a
"distributing corporation" or a "controlled corporation" (within the meaning of
Section 355(a)(1)(A) of the Code) in a distribution of stock qualifying or
intended to qualify for tax-free treatment under Section 355 of the Code (A) in
the two years prior to the date of this Agreement or (B) in a distribution that
could otherwise constitute part of a "plan" or "series of related transactions"
(within the meaning of Section 355(e) of the Code) in conjunction with the
Merger.

    (h)  For purposes of this Agreement:

    "TAXES" includes all forms of taxation imposed by any Federal, state, local,
foreign or other Governmental Entity, including income, franchise, property,
sales, use, excise, employment, unemployment, payroll, social security,
estimated, value added, ad valorem, transfer, recapture, withholding and other
Taxes of any kind, including all interest, penalties and additions thereto.

returns, declarations, statements, reports, schedules, forms and information
returns and any amended Tax return relating to Taxes.

the Filed Company SEC Documents or in the Company Disclosure Letter, from the
date of the most recent audited

                                       12
<PAGE>
financial statements included in the Filed Company SEC Documents to the date of
this Agreement, there has not been any adoption or amendment in any material
respect by the Company or any Company Subsidiary 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 or any Company
Subsidiary (collectively, "COMPANY BENEFIT PLANS"). Except as disclosed in the
Filed Company SEC Documents or in the Company Disclosure Letter, as of the date
of this Agreement there are not any employment, consulting, indemnification,
severance or termination agreements or arrangements between the Company or any
Company Subsidiary and any current or former employee, officer or director of
the Company or any Company Subsidiary, nor does the Company or any Company
Subsidiary have any general severance plan or policy.

    SECTION 3.11.  ERISA COMPLIANCE; EXCESS PARACHUTE PAYMENTS.  (a)  The
Company Disclosure Letter contains a list and brief description of all material
"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 "COMPANY PENSION PLANS"), "employee welfare benefit plans"
(as defined in Section 3(1) of ERISA) and all other Company Benefit Plans
maintained, or contributed to, by the Company or any Company Subsidiary for the
benefit of any current or former employees, officers or directors of the Company
or any Company Subsidiary. The Company has made available to Parent true,
complete and correct copies of (i) each Company Benefit Plan (or, in the case of
any unwritten Company Benefit Plan, a description thereof), (ii) the most recent
annual report on Form 5500 filed with the Internal Revenue Service with respect
to each Company Benefit Plan (if any such report was required), (iii) the most
recent summary plan description for each Company Benefit Plan for which such
summary plan description is required and (iv) each trust agreement and group
annuity contract relating to any Company Benefit Plan, if any.

    (b)  All Company Benefit Plans are in compliance in all material respects
with applicable Law (including, where applicable, the Code and ERISA). All
Company Pension Plans which are intended to be tax-qualified under
Section 401(a) of the Code have been the subject of determination letters from
the Internal Revenue Service to the effect that such Company Pension Plans are
qualified and their related trusts are exempt from Federal income taxes under
Sections 401(a) and 501(a), respectively, of the Internal Revenue Code of 1986,
as amended (the "CODE"), and no such determination letter has been revoked nor,
to the knowledge of the Company, has revocation been threatened. No such Company
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, nor has any such Company Pension Plan been amended since
December 31, 1998 in any respect that would materially increase its costs.

    (c)  No Company Pension Plan is a "defined benefit plan" within the meaning
of Section 3(35) of ERISA or is subject to the minimum funding standards of
Section 412 of the Code or Section 302 of ERISA, and neither the Company nor any
Company Subsidiary has any actual or contingent liability under any defined
benefit plan which it (or any affiliate) previously maintained or contributed to
(or was obligated to maintain or contribute to). None of the Company, any
Company Subsidiary, any officer of the Company or any Company Subsidiary or any
of the Company Benefit Plans which are subject to ERISA, including the Company
Pension Plans, any trusts created thereunder or any trustee or administrator
thereof, has engaged in a "prohibited transaction" (as such term is defined in
Section 406 of ERISA or Section 4975 of the Code) or any other breach of
fiduciary responsibility that could subject the Company, any Company Subsidiary
or any officer of the Company or any Company Subsidiary to any material tax or
penalty on prohibited transactions imposed by such Section 4975 or to any
material liability under Section 502(i) or 502(l) of ERISA.

                                       13
<PAGE>
    (d)  With respect to any Company Benefit Plan that is an employee welfare
benefit plan, (i) all such Company Benefit Plans are unfunded and no such
Company Benefit Plan is funded through a "welfare benefits fund" (as such term
is defined in Section 419(e) of the Code), (ii) each such Company Benefit Plan
that is a "group health plan" (as such term is defined in Section 5000(b)(1) of
the Code), complies in all material respects with the applicable requirements of
Section 4980B(f) of the Code and (iii) each such Company Benefit Plan (including
any such Plan covering retirees or other former employees) may be amended or
terminated without material liability to the Company and the Company
Subsidiaries on or at any time after the Effective Time, except with respect to
contributions, premiums or benefit claims (actual or contingent) with respect to
the period from the Effective Time to such termination.

    (e)  Other than payments that may be made to the persons listed in the
Company Disclosure Letter (the "PRIMARY COMPANY EXECUTIVES"), any amount that
could be received (whether in cash or property or the vesting of property) as a
result of the Offer, the Merger or any other Transaction by any employee,
officer or director of the Company or any of its affiliates 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, any other compensation arrangement or any Company Benefit Plan
currently in effect would not be characterized as an "excess parachute payment"
(as defined in Section 280G(b)(1) of the Code). Set forth in the Company
Disclosure Letter is (i) the estimated maximum amount that could be paid to each
Primary Company Executive as a result of the Offer, the Merger and the other
Transactions under all employment, severance and termination agreements, other
compensation arrangements and Company Benefit Plans currently in effect and
(ii) the "base amount" (as defined in Section 280G(b)(3) of the Code) for each
Primary Company Executive calculated as of the date of this Agreement.

    SECTION 3.12.  LITIGATION.  Except as disclosed in the Filed Company SEC
Documents or in the Company Disclosure Letter, there is no suit, action or
proceeding pending or, to the knowledge of the Company, threatened against or
affecting the Company or any Company Subsidiary (and, as of the date of this
Agreement, the Company is not aware of any basis for any such suit, action or
proceeding) that, individually or in the aggregate, has had or would reasonably
be expected to have a Company Material Adverse Effect, other than any action,
suit or proceeding filed or threatened after the date of this Agreement that is
based upon the same or substantially the same facts that serve as the basis for
any suit, action or proceeding disclosed in the Filed Company SEC Documents or
the Company Disclosure Letter, nor is there any Judgment outstanding against the
Company or any Company Subsidiary that has had or would reasonably be expected
to have a Company Material Adverse Effect.

    SECTION 3.13.  COMPLIANCE WITH APPLICABLE LAWS.  Except as disclosed in the
Filed Company SEC Documents or in the Company Disclosure Letter, the Company and
the Company Subsidiaries are in compliance with all applicable Laws, including
those relating to occupational health and safety and the environment, except for
instances of noncompliance that, individually and in the aggregate, have not had
and would not reasonably be expected to have a Company Material Adverse Effect.
Except as set forth in the Filed Company SEC Documents or in the Company
Disclosure Letter, neither the Company nor any Company Subsidiary has received
any written communication during the past two years from a Governmental Entity
that alleges that the Company or a Company Subsidiary is not in compliance in
any material respect with any applicable Law. Except as set forth in the Filed
Company SEC Documents or in the Company Disclosure Letter, the Company and the
Company Subsidiaries are in compliance in all material respects with the U.S.
Federal Food, Drug and Cosmetic Act, as amended (the "FDC ACT"), and applicable
regulations promulgated thereunder, and are in compliance in all material
respects with all FDA regulations, including the FDA's Quality System
Regulation, and any similar Laws applicable to the Company or any Company
Subsidiary, including the European Union Medical Device Directives. The Company
and the Company Subsidiaries have maintained quality assurance/quality control
practices and procedures in compliance in all material respects with good

                                       14
<PAGE>
manufacturing practices within the meaning of the FDC Act and applicable
regulations promulgated thereunder. This Section 3.13 does not relate to matters
with respect to Taxes, which are the subject of Section 3.09.

    SECTION 3.14.  CONTRACTS; DEBT INSTRUMENTS.  Except as disclosed in the
Filed SEC Documents or the Company Disclosure Letter, there are no contracts or
agreements that are material to the business, assets, condition (financial or
otherwise) or results of operations of the Company and the Company Subsidiaries
taken as a whole. Neither the Company nor any Company Subsidiary is 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 loan or credit agreement, note, bond, mortgage, indenture,
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,
individually and in the aggregate, have not had and would not reasonably be
expected to have a Company Material Adverse Effect.

    SECTION 3.15.  INTELLECTUAL PROPERTY.  (a)  The Company and the Company
Subsidiaries own, or are validly licensed or otherwise have the right to use,
all patents, patent rights (including patent applications and licenses),
know-how, trade secrets, trademarks, trademark rights, trade names, trade name
rights, service marks, service mark rights, copyrights and other proprietary
intellectual property rights and computer programs (collectively, "INTELLECTUAL
PROPERTY RIGHTS") which are material to the conduct of the business of the
Company and the Company Subsidiaries taken as a whole and the consummation of
the Transactions (other than the transactions set forth in Section 6.13) will
not conflict with, alter or impair any such Intellectual Property Rights. The
Company Disclosure Letter sets forth a description of all of the following with
respect to the Company and the Company Subsidiaries: material patents, material
patent rights (including patent applications and licenses), material inventions
that have been identified as active patent matters but for which applications
have not yet been filed, registrations and licenses of trademarks, trade names,
service marks and copyrights, and the geographical territories in which the
foregoing are applicable. Except as set forth in the Company Disclosure Letter,
no claims are pending or, to the knowledge of the Company, threatened that
(i) the Company or any of the Company Subsidiaries is infringing or otherwise
adversely affecting the rights of any person with regard to any Intellectual
Property Right or (ii) assert that any Intellectual Property Rights owned by the
Company or any Company Subsidiary ("OWNED INTELLECTUAL PROPERTY RIGHTS") are
invalid or unenforceable. To the knowledge of the Company, except as set forth
in the Filed Company SEC Documents or the Company Disclosure Letter, no person
is infringing the rights of the Company or any of the Company Subsidiaries with
respect to any Owned Intellectual Property Right.

    (b)  The Company has timely paid, or caused to be timely paid, all
maintenance, renewal and other similar fees, and has timely met any applicable
working requirements with respect to all Owned Intellectual Property Rights
listed in the Company Disclosure Letter or material to the Company and the
Company Subsidiaries taken as a whole, except as set forth in the Company
Disclosure Letter. With respect to Intellectual Property Rights other than Owned
Intellectual Property Rights ("LICENSED INTELLECTUAL PROPERTY RIGHTS") that are
listed in the Company Disclosure Letter or material to the Company and the
Company Subsidiaries taken at a whole, the Company is in compliance in all
material respects with any applicable license or similar agreement.

    (c)  All Owned Intellectual Property Rights listed in the Company Disclosure
Letter or material to the Company and its Subsidiaries taken as a whole, are
free and clear of any Liens (other than Liens that are not material in amount or
that would not reasonably be expected to materially interfere with such
Intellectual Property Rights) and may be freely transferred, assigned, licensed
or sublicensed except as set forth in the Company Disclosure letter. The
Company's licenses with respect to all Licensed Intellectual Property Rights
that are listed in the Company Disclosure Letter or material to the Company and
the Company Subsidiaries taken as a whole are free and clear of any Liens (other

                                       15
<PAGE>
than Liens that are not material in amount or that would not reasonably be
expected to materially interfere with such Licensed Intellectual Property
Rights).

based upon arrangements made by or on behalf of the Company. The estimated fees

financial point of view and a copy of the signed opinion has been provided to

    SECTION 3.18.  LENS EXPRESS, INC. SALE.  Following the closing of the sale
pursuant to the Asset Purchase Agreement by and among Lens Express, Inc., the
Company and Strategic Optical Holdings, Inc. dated May 4, 2000 (the "LENS

<PAGE>
to a Company Takeover Proposal (as defined in Section 5.02(e)) that the Company
Board determines, in good faith after consultation with outside counsel and
Chase Securities Inc. or another nationally recognized independent financial
advisor, is reasonably likely to lead to a Superior Company Proposal (as defined
in Section 5.02(e)), that was not solicited by the Company and that did not
otherwise result from a breach or a deemed breach of this Section 5.02(a), and
subject to compliance with Section 5.02(c),(x) furnish information with respect
to the Company to the person making such Company Takeover Proposal and its
Representatives pursuant to a customary confidentiality agreement and
(y) participate in discussions or negotiations with such person and its
Representatives regarding such Company Takeover Proposal. Without limiting the
foregoing, it is agreed that any violation of the restrictions set forth in the
preceding sentence by any Representative of the Company or any Company

Company or any Company Subsidiary or otherwise, shall be deemed to be a breach
of this Section 5.02(a) by the Company.

fulfill its fiduciary obligations under applicable Law, neither the Company

    (c)  The Company promptly shall advise Parent orally and, within two
business days, in writing of any Company Takeover Proposal or any inquiry with
respect to or that could reasonably be expected to lead to any Company Takeover
Proposal, the material terms and conditions of any such Company Takeover
Proposal (including any changes thereto) and the identity of the person making
any such Company Takeover Proposal or inquiry. The Company shall (i) keep Parent
fully informed of the status and details (including any change to the terms
thereof) of any such Company Takeover Proposal and (ii) provide to Parent as
soon as practicable after receipt or delivery thereof with copies of all

Proposal.

taking and disclosing to its stockholders a position contemplated by
Rule 14e-2(a) promulgated under the Exchange Act or from making any required

    merger, consolidation, dissolution, recapitalization or other business
    combination involving the Company or any Significant Subsidiary of the
    Company, (ii) any proposal for the issuance by the Company of over 20% of
    its equity securities as consideration for the assets or securities of
    another person or (iii) any proposal or offer to acquire in any manner,
    directly or indirectly, over 20% of the equity securities or consolidated
    total assets of the Company, in each case other than pursuant to the
    Transactions.

<PAGE>
    substantially all its assets, (i) on terms which the Company Board
    determines in good faith to be superior from a financial point of view to
    the holders of Company Common Stock to the Transactions (after consultation
    with the Company's financial advisor, which shall be Chase Securities Inc.
    or another nationally recognized independent financial advisor), taking into
    account all the terms and conditions of such proposal and this Agreement
    (including any proposal by Parent to amend the terms of the Transactions)

    all financial, regulatory, legal and other aspects of such proposal.

                                   ARTICLE VI
                             ADDITIONAL AGREEMENTS

    SECTION 6.01.  PREPARATION OF PROXY STATEMENT; STOCKHOLDERS MEETING.  (a)
The Company shall, as soon as practicable following the expiration of the Offer,
prepare and file with the SEC the Proxy Statement in preliminary form, and each
of the Company, Parent and Sub shall use their best efforts to respond as
promptly as practicable to any comments of the SEC with respect thereto. The
Company shall notify Parent promptly of the receipt of any comments from the SEC
or its staff and of any request by the SEC or its staff for amendments or
supplements to the Proxy Statement or for additional information and shall
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. If at any time prior to receipt of
the Company Stockholder Approval there shall occur any event that should be set
forth in an amendment or supplement to the Proxy Statement, the Company shall
promptly prepare and mail to its stockholders such an amendment or supplement.
The Company shall not mail any Proxy Statement, or any amendment or supplement
thereto, to which Parent reasonably objects. The Company shall use its best
efforts to cause the Proxy Statement to be mailed to the Company's stockholders
as promptly as practicable after filing with the SEC.

    (b)  The Company shall, as soon as practicable following the expiration of
the Offer, duly call, give notice of, convene and hold a meeting of its
stockholders (the "COMPANY STOCKHOLDERS MEETING") for the purpose of seeking the
Company Stockholder Approval. Subject to Section 5.02(b), the Company shall,
through the Company Board, recommend to its stockholders that they give the
Company Stockholder Approval. Without limiting the generality of the foregoing,
the Company agrees that its obligations pursuant to the first sentence of this
Section 6.01(b) shall not be affected by the commencement, public proposal,
public disclosure or communication to the Company of any Company Takeover
Proposal. Notwithstanding the foregoing, if Sub or any other subsidiary of
Parent shall acquire at least 90% of the outstanding shares of each series of
Company Capital Stock, 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 82 of the BCL.

    (c)  Parent shall cause all shares of Company Common Stock purchased
pursuant to the Offer and all other shares of Company Common Stock owned by
Parent, Sub or any other subsidiary of Parent to be voted in favor of the
approval of this Agreement.

    SECTION 6.02.  ACCESS TO INFORMATION; CONFIDENTIALITY.  The Company shall,
and shall cause each of its subsidiaries to, afford to Parent, and to Parent's
officers, employees, accountants, counsel, financial advisors and other
representatives, upon reasonable notice, reasonable access during normal
business hours during the period prior to the Effective Time to all their
respective properties, books, contracts, commitments, personnel and records and,
during such period, the Company shall, and shall cause each of its subsidiaries
to, 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; PROVIDED, HOWEVER, that the Company may withhold the

                                       22
<PAGE>
documents and information described in the Company Disclosure Letter to the
extent required to comply with the terms of a confidentiality agreement with a
third party in effect on the date of this Agreement; PROVIDED FURTHER, that the
Company shall use all reasonable efforts to obtain, as promptly as practicable,
any consent from such third party required to permit the Company to furnish such
documents and information to Parent. All information exchanged pursuant to this
Section 6.02 shall be subject to the confidentiality agreement dated
November 5, 1999, between the Company and Alcon Laboratories, Inc. (the
"CONFIDENTIALITY AGREEMENT").

    SECTION 6.03.  REASONABLE EFFORTS; NOTIFICATION.  (a) Upon the terms and
subject to the conditions set forth in this Agreement, each of the parties shall
use all reasonable efforts to take, or cause to be taken, all reasonable
actions, and to do, or cause to be done, and to assist and cooperate with the
other parties in doing, all things reasonably necessary, proper or advisable to
consummate and make effective, in the most expeditious manner practicable, the
Offer, the Merger and the other Transactions, 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 third parties, (iii) the
defending of any lawsuits or other legal proceedings, whether judicial or
administrative, challenging this Agreement or the consummation of the
Transactions, including, when reasonable, 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 and to fully carry out the purposes of
this Agreement; PROVIDED, HOWEVER, that the obligations set forth in this
sentence shall not be deemed to have been breached as a result of actions by the
Company expressly permitted under Section 5.02(b). In connection with and
without limiting the foregoing, the Company and the Company Board shall
(i) take all action necessary to ensure that no state takeover statute or
similar statute or regulation is or becomes applicable to any Transaction or
this Agreement and (ii) if any state takeover statute or similar statute or
regulation becomes applicable to this Agreement, take all action necessary to
ensure that the Offer, the Merger and the other Transactions may be consummated
as promptly as practicable on the terms contemplated by this Agreement and
otherwise to minimize the effect of such statute or regulation on the Offer, the
Merger and the other Transactions. Nothing in this Agreement shall be deemed to
require any party to waive any substantial rights or agree to any substantial
limitation on its operations or to dispose of any significant asset or
collection of assets. As promptly as practicable after the consummation of the
Offer, the Company shall use all reasonable efforts to notify Parent of any
actions or nonactions of, waivers, consents and approvals from, and
registrations and filings with, Governmental Entities, and any consents,
approvals or waivers from third parties, that would be required in connection
with the consummation of the Merger in the event that Parent elects pursuant to
Section 1.03 to merge the Company with and into Sub instead of merging Sub into
the Company.

    (b)  The Company shall give prompt notice to Parent, and Parent or Sub shall
give prompt notice to the Company, of (i) any representation or warranty made by
it contained in this Agreement that is qualified as to materiality becoming
untrue or inaccurate in any respect or any such representation or warranty that
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 complied with or satisfied by it under
this Agreement; PROVIDED, HOWEVER, that no such notification shall affect the
representations, warranties, covenants or agreements of the parties or the
conditions to the obligations of the parties under this Agreement.

    SECTION 6.04.  STOCK OPTIONS.  (a) As soon as practicable following the date
of this Agreement, the Company Board (or, if appropriate, any committee
administering the Company Stock Plans) shall adopt such resolutions or take such
other actions as are required to adjust the terms of all outstanding Company
Stock Options and all outstanding Company SARs, in each case whether vested or
unvested, heretofore granted under any Company Stock Plan to provide that each
such Company Stock Option (and any Company SAR related thereto) outstanding
immediately prior to the first acceptance for payment of shares of Company
Common Stock pursuant to the Offer shall be canceled in exchange for a cash
payment by the Company as soon as practicable following the first acceptance for
payment of shares of Company Common Stock pursuant to the Offer of an amount
equal to (i) the excess, if any, of (x) the highest price per share of Company
Common Stock to be paid pursuant to the Offer over (y) the exercise price per
share of Company Common Stock subject to such Company Stock Option, multiplied
by (ii) the number of shares of Company Common Stock for which such Company
Stock Option shall not theretofore have been exercised. The Company will be
responsible for any required reporting to Federal, state or local tax
authorities.

    (b)  All amounts payable pursuant to this Section 6.04 shall be subject to
any required withholding of Taxes or proof of eligibility of exemption therefrom
and shall be paid without interest by the Company as soon as practicable
following the first acceptance for payment of shares of Company Common Stock
pursuant to the Offer. The Company shall use its best efforts to obtain all
consents of the holders of Company Stock Options as shall be necessary to
effectuate the foregoing. Notwithstanding anything to the contrary contained in
this Agreement, payment shall, at Parent's request, be withheld in respect of
any Company Stock Option until all necessary consents with respect to such
Company Stock Option are obtained.

    (c)  The Company Stock 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, and the
Company shall ensure that following the Effective Time no holder of a Company
Stock Option or Company SAR or any participant in any Company Stock Plan or
other Company Benefit Plan shall have any right thereunder to acquire any
capital stock of the Company or the Surviving Corporation.

    (d)  In this Agreement:

        "COMPANY STOCK OPTION" means any option to purchase Company Common Stock
    granted under any Company Stock Plan.

        "COMPANY SAR" means any stock appreciation right linked to the price of
    Company Common Stock and granted under any Company Stock Plan.

        "COMPANY STOCK PLANS" means the 1992 Stock Option Plan for Outside
    Directors, the 1999 Outside Director Compensation Plan, the 1987 Stock
    Option Plan, the 1997 Stock Option Plan, the Employee Stock Purchase Plan
    and all agreements under which there are outstanding options to purchase
    Company Common Stock granted to employees, consultants or any other person.

    SECTION 6.05.  BENEFIT PLANS.  (a)  Except as set forth in Section 6.04,
Parent agrees to cause the Surviving Corporation (i) to maintain for a period of
one year after the Effective Time the Company Benefit Plans (other than
equity-based plans) in effect on the date of this Agreement or (ii) to provide
benefits (other than equity-based plans) to each current employee of the Company
and its subsidiaries that are not materially less favorable in the aggregate to
such employees than those benefits in effect for such employees on the date of
this Agreement.

    (b)  In addition to the agreement set forth in Section 6.05(a), from and
after the Control Date and from and after the Effective Time, Parent shall cause
the Company or the Surviving Corporation, as applicable, to honor in accordance
with their respective terms (as in effect on the date of this Agreement), all
the Company's employment, severance and termination agreements, plans and
policies

                                       24
<PAGE>
disclosed in the Company Disclosure Letter, including any change in control
provisions contained therein.

    (c)  With respect to any "employee benefit plan", as defined in
Section 3(3) of ERISA, maintained by Parent or any of its subsidiaries
(including any severance plan), for all purposes, including determining
eligibility to participate and vesting, service with the Company or any Company
Subsidiary shall be treated as service with Parent or any of its subsidiaries;
PROVIDED, HOWEVER, that such service need not be recognized to the extent that
such recognition would result in any duplication of benefits.

    SECTION 6.06.  INDEMNIFICATION.  (a)  Parent shall, to the fullest extent
permitted by Law, cause the Company (from and after the Control Date) and the
Surviving Corporation (from and after the Effective Time) to honor all the
Company's obligations to indemnify, defend and hold harmless (including any
obligations to advance funds for expenses) the current and former directors and
officers of the Company and its subsidiaries against all losses, claims, damages
or liabilities arising out of acts or omissions by any such directors and
officers occurring prior to the Effective Time to the maximum extent that such
obligations of the Company exist on the date of this Agreement, whether pursuant
to the Company Charter, the Company By-laws, the BCL, individual indemnity
agreements or otherwise, and such obligations shall survive the Merger and shall
continue in full force and effect in accordance with the terms of the Company
Charter, the Company By-laws, the BCL and such individual indemnity agreements
from the Effective Time until the expiration of the applicable statute of
limitations with respect to any claims against such directors or officers
arising out of such acts or omissions. In the event a current or former director
or officer of the Company or any of its subsidiaries is entitled to
indemnification under this Section 6.06(a), such director or officer shall be
entitled to reimbursement from the Company (from and after the Control Date) or
the Surviving Corporation (from and after the Effective Time) for reasonable
attorney fees and expenses incurred by such director or officer in pursuing such
indemnification, including payment of such fees and expenses by the Surviving
Corporation or the Company, as applicable, in advance of the final disposition
of such action upon receipt of an undertaking by such current or former director
or officer to repay such payment if it shall be adjudicated that such current or
former director or officer was not entitled to such payment.

    (b)  From and after the Control Date and for a period of six years after the
Effective Time, Parent shall cause to be maintained in effect the current
policies of directors' and officers' liability insurance maintained by the
Company (provided that Parent may either (i) substitute therefor policies with
reputable and financially sound carriers or (ii) maintain self insurance or
similar arrangements through a financially sound insurance affiliate of Parent,
in each case of at least the same coverage and amounts containing terms and
conditions which are no less advantageous) with respect to claims arising from
or related to facts or events which occurred at or before the Effective Time;
PROVIDED, HOWEVER, that Parent shall not be obligated to make annual premium
payments for such insurance to the extent such premiums exceed 200% of the
annual premiums paid as of the date hereof by the Company for such insurance
(such 200% amount, the "MAXIMUM PREMIUM"). If such insurance coverage cannot be
obtained at all, or can only be obtained at an annual premium in excess of the
Maximum Premium, Parent shall maintain the most advantageous policies of
directors' and officers' insurance obtainable for an annual premium equal to the
Maximum Premium. The Company represents to Parent that the Maximum Premium is
$400,000.

    (c)  The Company will maintain, through the Effective Time, the Company's
existing directors' and officers' insurance in full force and effect without
reduction of coverage.

    (d)  The By-Laws of the Surviving Corporation shall contain the provisions
that are set forth, as of the date of this Agreement, in Article VIII of the
By-Laws of the Company, which provisions shall not be amended, repealed or
otherwise modified for a period of six years from the Effective Time in any
manner that would affect adversely the rights thereunder of individuals who at
or at any time prior

                                       25
<PAGE>
to the Effective Time were directors, officers, employees or other agents of the
Company (and during such period the Articles of Organization of the Company
shall not be amended, repealed or otherwise modified in any manner that would
have the effect of so amending, repealing or otherwise modifying such provisions
of the By-Laws).

    (e)  If the Surviving Corporation or any of its 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
and the continuing or surviving entity does not assume the obligations of the
Surviving Corporation set forth in this Section 6.06, or (ii) transfers all or
substantially all of its properties and assets to any person, then, and in each
such case, proper provision shall be made so that the successors and assigns of
the Surviving Corporation assume, as a matter of law or otherwise, the
obligations set forth in this Section 6.06.

    (f)  Parent guarantees that if for any reason the Company or the Surviving
Corporation, as the case may be, shall not meet its obligations pursuant to this
Section 6.06, it shall meet such obligations in full when and as such
obligations arise.

    SECTION 6.07.  FEES AND EXPENSES.  (a)  Except as provided below, all fees
and expenses incurred in connection with the Merger and the other Transactions
shall be paid by the party incurring such fees or expenses, whether or not the
Merger is consummated.

    (b)  The Company shall pay to Parent a fee of $32.5 million if: (i) this
Agreement is terminated pursuant to Section 8.01(b)(iii) as a result of the
failure of the condition set forth in paragraph (d) of Exhibit A; (ii) the
Company terminates this Agreement pursuant to Section 8.01(e); (iii) Parent
terminates this Agreement pursuant to Section 8.01(d)(i) or 8.01(d)(ii) as a
result of a material breach of Section 5.02; (iv) after the date of this
Agreement, any person makes a Company Takeover Proposal, (A) the Offer shall
have remained open until the scheduled expiration date immediately following the
date such Company Takeover Proposal is made, (B) the Minimum Tender Condition is
not satisfied at such expiration date, (C) this Agreement is terminated pursuant
to Section 8.01(b)(i) or 8.01(b)(iii) (other than as a result of the failure of
the condition set forth in paragraph (d) of Exhibit A) and (D) within 12 months
of such termination the Company enters into a definitive agreement to
consummate, or consummates, the transactions contemplated by a Company Takeover
Proposal; or (v) subject to Section 6.07(c), this Agreement is terminated
pursuant to Section 8.01(c) as a result of a wilful breach by the Company and
within 12 months of such termination the Company enters into a definitive
agreement to consummate, or consummates, the transactions contemplated by a
Company Takeover Proposal. Any fee due under this Section 6.07(b) shall be paid
by wire transfer of same-day funds on the date of termination of this Agreement
(except that in the case of clause (iv) or (v) above such payment shall be made
on the date of execution of such definitive agreement or, if earlier,
consummation of such transactions).

    (c)  If the Company becomes obligated to pay a fee under Section 6.07(b) as
a result of a termination pursuant to Section 8.01(c), Parent may elect not to
receive the fee and may instead pursue any and all rights, claims and causes of
action it may have under Law with respect to the breach giving rise to such
right of termination. If Parent elects to receive the fee, and the Company pays
the fee as required by Section 6.07(b), the payment by the Company of such fee
shall be Parent's sole remedy with respect to such breach and Parent shall
waive, to the fullest extent permitted by Law, any and all rights, claims and
causes of action (other than claims of, or causes of action arising from, fraud)
it may have against the Company with respect to such breach.

    SECTION 6.08.  PUBLIC ANNOUNCEMENTS.  Parent and Sub, on the one hand, and
the Company, on the other hand, shall 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 Offer, the Merger and the
other Transactions and shall not issue any such press release or make any such
public statement prior to such consultation, except as may be required by
applicable Law (including foreign

                                       26
<PAGE>
regulations relating to competition), court process or by obligations pursuant
to any listing agreement with any national securities exchange.

    SECTION 6.09.  TRANSFER TAXES.  All stock transfer, real estate transfer,
documentary, stamp, recording and other similar Taxes (including interest,
penalties and additions to any such Taxes) ("TRANSFER TAXES") incurred in
connection with the Transactions shall be paid by the party upon whom the
primary burden for payment is placed by the applicable law. Each party shall
cooperate with the other in preparing, executing and filing any Tax Returns with
respect to such Transfer Taxes and shall use reasonable efforts to avail itself
of any available exemptions from such Transfer Taxes, and shall cooperate in
providing any information and documentation that may be necessary to obtain such
exemptions.

    SECTION 6.10.  DIRECTORS.  Promptly upon the first acceptance for payment
of, and payment by Sub for, any shares of Company Common Stock pursuant to the
Offer, Sub shall be entitled to designate such number of directors on the
Company Board as will give Sub, subject to compliance with Section 14(f) of the
Exchange Act, representation on the Company Board equal to at least that number
of directors, rounded up to the next whole number, which is the product of
(a) the total number of directors on the Company Board (giving effect to the
directors elected pursuant to this sentence) multiplied by (b) the percentage
that (i) such number of shares of Company Common Stock so accepted for payment
and paid for by Sub plus the number of shares of Company Common Stock otherwise
owned by Sub or any other subsidiary of Parent bears to (ii) the number of such
shares outstanding, and the Company shall, at such time, cause Sub's designees
to be so elected; PROVIDED, HOWEVER, that in the event that Sub's designees are
appointed or elected to the Company Board, until the Effective Time the Company
Board shall have at least three directors who are directors on the date of this
Agreement and who are not officers of the Company (the "INDEPENDENT DIRECTORS");
and PROVIDED FURTHER that, in such event, if the number of Independent Directors
shall be reduced below three for any reason whatsoever, any remaining
Independent Directors (or Independent Director, if there shall be only one
remaining) shall be entitled to designate persons to fill such vacancies who
shall be deemed to be Independent Directors for purposes of this Agreement or,
if no Independent Directors then remain, the other directors shall designate
three persons to fill such vacancies who are not officers, stockholders or
affiliates of the Company, Parent or Sub, and such persons shall be deemed to be
Independent Directors for purposes of this Agreement. 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 shall make such mailing with
the mailing of the Schedule 14D-9 (provided that Sub shall have provided to the
Company on a timely basis all information required to be included in the
Information Statement with respect to Sub's designees). In connection with the
foregoing, the Company shall promptly, at the option of Sub, either increase the
size of the Company Board 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 the Company Board as provided above.

    SECTION 6.11.  RIGHTS AGREEMENT; CONSEQUENCES IF RIGHTS TRIGGERED.  The
Company Board shall take all action requested in writing by Parent in order to
render the Company Rights inapplicable to the Offer, the Merger and the other
Transactions. Except as approved in writing by Parent, the Company Board shall
not (i) amend the Company Rights Agreement, (ii) redeem the Company Rights or
(iii) take any action with respect to, or make any determination under, the
Company Rights Agreement, in each case in a manner adverse to Parent or Sub. If
any Distribution Date, Stock Acquisition Date or Common Stock Event occurs under
the Company Rights Agreement at any time during the period from the date of this
Agreement to the Effective Time, the Company and Parent shall make such
adjustment to the Offer Price as the Company and Parent shall mutually agree so
as to preserve the economic benefits that the Company and Parent each reasonably
expected on the date of

                                       27
<PAGE>
this Agreement to receive as a result of the consummation of the Offer, the
Merger and the other Transactions.

    SECTION 6.12.  STOCKHOLDER LITIGATION.  The Company shall give Parent the
opportunity to participate in the defense or settlement of any stockholder
litigation against the Company and its directors relating to any Transaction;
PROVIDED, HOWEVER, that Parent shall have the right to prevent the Company from
entering into any such settlement without Parent's consent if Parent agrees to
indemnify the Company and each director of the Company for the amount of its,
his or her liability, if any, arising from the underlying claim, net of any
insurance proceeds received by such person, that is in excess of the amount for
which such person would have been liable under such settlement.

    SECTION 6.13.  TRANSFERS OF CERTAIN INTANGIBLE ASSETS.  No later than
simultaneously with the first acceptance for payment of, and payment by Sub for,
at least two-thirds of the Fully Diluted Shares (as defined in Exhibit A)
pursuant to the Offer, (a) the Company shall cause its subsidiary, Autonomous
Technologies Corp., a Delaware corporation ("AUTONOMOUS"), to transfer
(x) certain of the Intellectual Property Rights of Autonomous and its
subsidiaries and (y) certain licenses, approvals and registrations issued by, or
filed with, the FDA, and all other Governmental Entities performing similar
functions, and all rights therein, of Autonomous and its subsidiaries with
respect to any products of Autonomous and its subsidiaries to Alcon
Universal Ltd., a Swiss corporation ("AUL"), in exchange for a cash payment by
AUL equal to the fair market value of the transferred assets, and (b) the
Company shall transfer to AUL all of the outstanding shares of stock in its
subsidiary, Summit Technology Ireland B.V., a Netherlands corporation
("DUTCHCO"), in exchange for a cash payment by AUL equal to the net book value
of DutchCo). If any consent required to transfer an asset pursuant to this
Section 6.13 has not been obtained prior to the time at which such transfer
would otherwise occur, Parent and the Company shall cooperate in any lawful and
reasonable arrangement proposed by Parent under which AUL shall obtain the
economic claims, rights and benefits under such asset until such consent has
been obtained.

Stockholder Approval, if required.

    (b)  ANTITRUST. The waiting period (and any extension thereof) applicable to
the Merger under the HSR Act shall have been terminated or shall have expired.
Any consents, approvals and filings under any other foreign antitrust Law the
absence of which would prohibit the consummation of Merger, shall have been
obtained or made.

    (c)  NO INJUNCTIONS OR RESTRAINTS. No statute, rule, regulation, executive
order, decree, temporary restraining order, preliminary or permanent injunction
or other order enacted, entered, promulgated, enforced or issued by any
Governmental Entity or other legal restraint or prohibition preventing the
consummation of the Merger or the other Transactions shall be in effect;
PROVIDED, HOWEVER, that prior to asserting this condition each of the parties
shall have used all reasonable efforts to prevent the entry of any such
injunction or other order and to appeal as promptly as possible any such
injunction or other order that may be entered.

    (d)  ACCEPTANCE OF SHARES PURSUANT TO THE OFFER. Sub shall have accepted
shares of Company Common Stock for payment pursuant to the Offer; PROVIDED, that
the obligation of a party to effect the Merger shall not be conditioned on the
fulfillment of the condition set forth in this clause (d) if the failure of Sub
to accept shares of Company Common Stock for payment pursuant to the Offer shall

Agreement by such party.

                       TERMINATION, AMENDMENT AND WAIVER

    SECTION 8.01.  TERMINATION.  This Agreement may be terminated at any time
prior to the Effective Time, whether before or after receipt of Company
Stockholder Approval:

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

    (b) by either Parent or the Company:

        (i) if the Offer is not consummated on or before November 26, 2000 (the
    "OUTSIDE DATE"), unless the failure to consummate the Offer is the result of
    a wilful and material breach of this Agreement by the party seeking to
    terminate this Agreement;

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

        (iii) if as the result of the failure of any of the conditions set forth
    in Exhibit A to this Agreement, the Offer shall have terminated or expired
    in accordance with its terms without Sub having accepted shares of Company
    Common Stock for payment pursuant to the Offer; PROVIDED, HOWEVER, that the
    right to terminate this Agreement pursuant to this clause (iii) shall not be
    available to any party whose failure to fulfill 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 wilful breach of any representation or warranty under this
    Agreement by such party; or

        (iv) if, upon a vote at a duly held meeting to obtain the Company
    Stockholder Approval, the Company Stockholder Approval is not obtained;
    PROVIDED, that Parent may not terminate this Agreement under this
    Section 8.01(b)(iv) if the Company Common Stock owned by Sub, Parent or any
    other subsidiary of Parent shall not have been voted in favor of obtaining
    the Company Stockholder Approval;

    (c) by Parent, if the Company breaches or fails to perform in any material
respect any of its representations, warranties or covenants contained in this
Agreement (other than a breach or failure to perform for which Parent has the
right to terminate this Agreement pursuant to Section 8.01(d)(ii)), which breach
or failure to perform (i) would give rise to the failure of a condition set
forth in Exhibit A, and (ii) cannot be or has not been cured within 30 days
after the giving of written notice to the Company of such breach (provided that
Parent is not then in material breach of any representation, warranty or
covenant contained in this Agreement); or

    (d) by Parent prior to the first acceptance of shares of Company Common
Stock for payment pursuant to the Offer:

        (i) if the Company Board or any committee thereof withdraws or modifies
    in a manner adverse to Parent or Sub, or publicly proposes to withdraw or
    modify in a manner adverse to Parent or Sub, its approval or recommendation
    of this Agreement, the Offer or the Merger, fails to recommend to the
    Company's stockholders that they accept the Offer and give the Company
    Stockholder Approval or publicly approves or recommends, or publicly
    proposes to approve or recommend, any Company Takeover Proposal; or

        (ii) if the Company or any of its officers, directors, employees,
    representatives or agents takes any of the actions that would be proscribed
    by Section 5.02 but for the exceptions therein allowing certain actions to
    be taken pursuant to the proviso in the first sentence of Section 5.02(a);
    or

                                       29
<PAGE>
    (e) by the Company prior to the first acceptance of shares of Company Common
Stock for payment pursuant to the Offer in accordance with Section 8.05(b);
PROVIDED, HOWEVER, that the Company shall have complied with all provisions
thereof, including the notice provisions therein; or

    (f) by the Company prior to the first acceptance of shares of Company Common
Stock for payment pursuant to the Offer, if Parent breaches or fails to perform
in any material respect any of its representations, warranties or covenants
contained in this Agreement, which breach or failure to perform cannot be or has
not been cured within 30 days after the giving of written notice to Parent of
such breach (provided that the Company is not then in material breach of any
representation, warranty or covenant contained in this Agreement).

    SECTION 8.02.  EFFECT OF TERMINATION.  In the event of termination of this
Agreement by either the Company or Parent as provided in Section 8.01, this
Agreement shall forthwith become void and have no effect, without any liability
or obligation on the part of Parent, Sub or the Company, other than
Section 3.16, Section 4.06, the last sentence of Section 6.02, Section 6.07,
this Section 8.02 and Article IX, which provisions shall survive such
termination, and except to the extent that such termination results from the
wilful and material breach by a party of any representation, warranty or
covenant set forth in this Agreement.

    SECTION 8.03.  AMENDMENT.  This Agreement may be amended by the parties at
any time before or after receipt of the Company Stockholder Approval; PROVIDED,
HOWEVER, that after receipt of the Company Stockholder Approval, there shall be
made no amendment that by Law requires further approval by the stockholders of
the Company without the further approval of such stockholders; and PROVIDED,
FURTHER, that after this Agreement is adopted by the Company's stockholders, no
such amendment or modification shall be made that reduces the amount or changes
the form of Merger Consideration or otherwise materially and adversely affects
the rights of the Company's stockholders hereunder, without the further approval
of such stockholders. This Agreement may not be amended except by an instrument
in writing signed on behalf of each of the parties.

    SECTION 8.04.  EXTENSION; WAIVER.  At any time prior to the Effective Time,
the parties may (a) extend the time for the performance of any of the

the representations and warranties contained in this Agreement or in any
document delivered pursuant to this Agreement or (c) subject to the proviso of
Section 8.03, waive compliance with any of the agreements or conditions
contained in this Agreement. Any agreement on the part of a party to any such
extension or waiver shall be valid only if set forth in an instrument in writing
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 such rights.

    SECTION 8.05.  PROCEDURE FOR TERMINATION, AMENDMENT, EXTENSION OR
WAIVER.  (a) A termination of this Agreement pursuant to Section 8.01, an
amendment of this Agreement pursuant to Section 8.03 or an extension or waiver
pursuant to Section 8.04 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, that in the case of the
Company, such action shall also require action by a majority of the Independent
Directors.

only if (i) the Company Board has received a Superior Company Proposal, (ii) in
light of such Superior Company Proposal the Company Board shall have determined
in good faith, after consultation with outside counsel, that it is necessary for
the Company Board to withdraw or modify its approval or recommendation of this
Agreement, the Offer or the Merger in order to act in a manner consistent with
its fiduciary duty under applicable Law, (iii) the Company has notified Parent
in writing of the determinations described in clause (ii) above, (iv) at least
three business days following receipt by Parent of the notice referred to in
clause (iii) above, and taking into account any revised proposal made by Parent
since receipt of the notice referred to in clause (iii) above, such Superior
Company

                                       30

Agreement), (vi) the Company has previously paid the fee due under
Section 6.07, (vii) the Company Board concurrently approves, and the Company
concurrently enters into, a definitive agreement providing for the

shall have been validly tendered and not withdrawn prior to the expiration of

HSR Act applicable to the purchase of shares of Company Common Stock pursuant to
the Offer shall have expired or been terminated. The term "FULLY DILUTED SHARES"

convertible into such voting securities. Furthermore, notwithstanding any other
term of the Offer or this Agreement, Sub shall not be required to accept for
payment or, subject as aforesaid, to pay for any shares of Company Common Stock
not theretofore accepted for payment or paid for, and may terminate or amend the
Offer, (A) with the consent of the Company or (B) without the consent of the
Company at any time on or after the date of this Agreement and before the first
acceptance of such shares for payment or the payment therefor when any of the
following conditions exists:

        (a) there shall be threatened or pending any suit, action or proceeding
    by any Governmental Entity, or pending any suit, action or proceeding with a
    reasonable likelihood of success by any other person, (i) challenging the
    acquisition by Parent or Sub of any Company Common Stock, seeking to
    restrain or prohibit the making or consummation of the Offer or the Merger
    or any other Transaction, or seeking to obtain from the Company, Parent or
    Sub any damages that are material in relation to the Company and its
    subsidiaries taken as a whole, (ii) seeking to prohibit or limit the
    ownership or operation by the Company, Parent or any of their respective
    subsidiaries of any material portion of the business or assets of the
    Company and its subsidiaries taken as whole or Parent and its subsidiaries
    taken as a whole, or to compel the Company, Parent or any of their
    respective subsidiaries to dispose of or hold separate any material portion
    of the business or assets of the Company and its subsidiaries taken as whole
    or Parent and its subsidiaries taken as a whole, as a result of the Offer,
    the Merger or any other Transaction, (iii) seeking to impose limitations on
    the ability of Parent or Sub to acquire or hold, or exercise full rights of
    ownership of, any shares of Company Common Stock, including the right to
    vote the Company Common Stock acquired by it on all matters properly
    presented to the stockholders of the Company or (iv) seeking to prohibit
    Parent or any of its subsidiaries from effectively controlling in any
    material respect the business or operations of the Company and the Company
    Subsidiaries;

        (b) any Law or Judgment enacted, entered, enforced, promulgated, amended
    or issued with respect to, or deemed applicable to, or any required consent
    or approval withheld with respect to, (i) Parent, the Company or any of
    their respective subsidiaries or (ii) the Offer, the Merger or any other
    Transaction, by any Governmental Entity that is reasonably likely to result,
    directly or indirectly, in any of the consequences referred to in
    paragraph (a) above;

        (c) except as disclosed in the Filed Company SEC Documents or the
    Company Disclosure Letter, since the date of the most recent audited
    financial statements included in the Filed Company SEC Documents there shall
    have occurred any event, change, effect or development that, individually or
    in the aggregate, has had or would reasonably be expected to have, a Company
    Material Adverse Effect;
<PAGE>
        (d) the Company Board or any committee thereof shall have withdrawn or
    modified in a manner adverse to Parent or Sub, or publicly proposed to
    withdraw or modify in a manner adverse to Parent or Sub, its approval or
    recommendation of this Agreement, the Offer or the Merger, failed to
    recommend to the Company's stockholders that they accept the Offer and give
    the Company Stockholder Approval or approved or recommended, or publicly
    proposed to approve or recommend, any Company Takeover Proposal;

        (e) any representation and warranty of the Company in this Agreement
    that is qualified as to materiality shall not be true and correct or any
    such representation and warranty that is not so qualified shall not be true
    and correct in any material respect, as of the date of this Agreement and as
    of such time, except to the extent such representation and warranty
    expressly relates to an earlier date (in which case on and as of such
    earlier date);

        (f) the Company shall have failed to perform in any material respect any
    obligation or to comply in any material respect with any agreement or
    covenant of the Company to be performed or complied with by it under this
    Agreement, which failure to perform or comply cannot be or has not been
    cured within five days after the giving of written notice to the Company of
    such breach; or

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

which, in the sole and good faith judgment of Sub or Parent, in any such case,
and regardless of the circumstances giving rise to any such condition (including
any action or inaction by Parent or any of its affiliates), makes it inadvisable
to proceed with such acceptance for payment or payment.

    The foregoing conditions are for the sole benefit of Sub and Parent and,
subject to Section 1.01(a), may be asserted by Sub or Parent regardless of the
circumstances giving rise to such condition or may be waived by Sub and Parent
in whole or in part at any time and from time to time in their sole discretion
(subject to the terms of this Agreement). The failure by Parent, Sub or any
other affiliate of Parent 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.

ONE:          The Board of Directors may make, amend or repeal the By-Laws
              of the corporation in whole or in part, except with respect
              to any provision thereof which by law or the By-Laws
              requires action by the stockholders. Any by-law adopted by
              the Board of Directors may be amended or repealed by the
              stockholders.

TWO:          Meetings of the stockholders may be held anywhere in the
              United States.

              conduct by itself.

FOUR:         Except as specifically authorized by statute, no stockholder
              shall have any right to examine any property or any books,
              accounts or other writings of the corporation if there is
              reasonable ground for belief that such examination will for
              any reason be adverse to the interests of the corporation,
              and a vote of the directors refusing permission to make such
              examination and setting forth that in the opinion of the
              directors such reexamination would be adverse to the
              interests of the corporation shall be prima facie evidence
              that such examination would be adverse to the interests of
              the corporation. Every such examination shall be subject to

              amounts, if any, shall be reserved for any corporate
              purpose, and what amounts, if any, shall be declared as
              dividends. All surplus shall be available for any corporate
              purpose, including the payment of dividends.

SIX:          The purchase or other acquisition or retention by the
              corporation of shares of its own capital stock shall not be
              deemed a reduction of its capital stock. Upon any reduction
              of capital or capital stock, no stockholder shall have any
              right to demand any distribution from the corporation,
              except as and to the extent that the stockholders shall have
              provided at the time of authorizing such reduction.

SEVEN:        In the absence of fraud, no contract or transaction between
              the corporation and one or more of its directors or
              officers, or between the corporation and any other

              officers are directors, trustees or officers, or in which
              any of them has any financial or other interest, shall be
              void or voidable, or in any way affected, solely for this
              reason, or solely because the director or officer is present
              at or participates in the meeting of the Board of Directors
              or committee thereof which authorizes, approves or ratifies
              the contract or transaction, or solely because his/her or
              their votes are counted for such purposes, if:

                  (i) The material facts as to his/her relationship or
                      interest and as to the contract or transaction are
                      disclosed or are known to the Board of Directors or
                      the committee which authorizes, approves or ratifies
                      the contract or transaction, and the board or
                      committee in good faith authorizes, approves or
                      ratifies the contract or transaction by the
                      affirmative vote of a majority of the disinterested
                      directors, even though the disinterested directors
                      be less than a quorum; or

                      interest and as to the contract or transaction are
                      disclosed or are known to the stockholders entitled
                      to vote thereon, and the contract or transaction is
                      specifically authorized, approved or ratified in
                      good faith by vote of the stockholders; or

                  (iii) The contract or transaction is fair as to the
                      corporation as of the time it is authorized,
                      approved or ratified by the Board of Directors, a
                      committee thereof, or the stockholders.

              Common or interested directors may be counted in determining
              the presence of a quorum at a meeting of the Board of
              Directors or of a committee thereof which authorizes,
              approves or ratifies the contract or transaction. No
              director or officer of the corporation shall be liable or
              accountable to the corporation or to any of its stockholders
              or creditors or to any other person, either for any loss to
              the corporation or to any other person or for any gains or
              profits realized by such director or officer, by reason of
              any contract or transaction as to which clauses (i) or
              (ii) or (iii) above are applicable.

EIGHT:        No director of the corporation shall be personally liable to
              the corporation or its stockholders for monetary damages for
              breach of fiduciary duty as a director notwithstanding any
              provision of law imposing such liability; provided, however,
              that, to the extent required by applicable law, this
              provision shall not eliminate or limit the liability of a
              director, (i) for any breach of the director's duty of
              loyalty to the corporation or its stockholders, (ii) for
              acts or omissions not in good faith or which involve

              (iii) under Section 61 or 62 or successor provisions of the
              Massachusetts Business Corporation Law, or (iv) for any
              transaction from which the director derived an improper
              personal benefit. This provision shall not eliminate or
              limit the liability of a director for any act or omission
              occurring prior to March 18, 1987. No amendment or repeal of
              this provision shall apply to or have any effect on the
              liability or alleged liability of any director for or with
              respect to any acts or omissions of such director occurring
              prior to such amendment or repeal.

CHASE SECURITIES INC.
270 Park Avenue
New York, NY 10017-2070

                                                                    May 26, 2000

    Board of Directors
    Summit Autonomous Inc.
    21 Hickory Drive
    Waltham, Massachusetts 02451

    Members of the Board:

        You have informed us that Summit Autonomous Inc. (the "Company"), Alcon
    Holdings Inc. (the "Acquiror") and Alcon Acquisition Corp., a newly formed,
    wholly owned subsidiary of the Acquiror (the "Acquisition Sub"), propose to
    enter into an Agreement and Plan of Merger (the "Agreement") pursuant to
    which (i) the Acquiror and the Acquisition Sub would commence a tender offer
    (the "Tender Offer") for all outstanding shares of the common stock, par
    value $0.01 per share, of the Company (the "Company Shares") for $19.00 per
    share, net to the seller in cash (the "Consideration"), and (ii) the
    Acquisition Sub would be merged with the Company in a merger (the "Merger"),
    in which each Company Share not acquired in the Tender Offer, other than
    Company Shares held in treasury or owned by any subsidiary of the Company or
    by the Acquiror or any subsidiary of the Acquiror, or as to which appraisal
    rights have been perfected, would be converted into the right to receive the
    Consideration. The Tender Offer and the Merger, taken together, are referred
    to as the "Transaction".

        You have asked us whether, in our opinion, the Consideration to be
    received by the holders of the Company Shares pursuant to the Transaction is
    fair, from a financial point of view, to such holders.

        In arriving at the opinion set forth below, we have, among other things:

       (a) reviewed a draft dated May 26, 2000 of the Agreement;

       (b) reviewed certain publicly available business and financial
           information we deemed relevant relating to the Company and the
           industries in which it operates;

       (c) reviewed certain internal non-public financial and operating data and
           forecasts provided to us by the management of the Company relating to
           its business;

       (d) discussed, with members of the senior management of the Company, the
           Company's operations, historical financial statements and future
           prospects;
<PAGE>
       (e) compared the financial and operating performance of the Company with
           publicly available information concerning certain other companies we
           deemed comparable and reviewed the relevant historical stock prices
           of the Company Shares and certain publicly traded securities of such
           other companies;

       (f) compared the proposed financial terms of the Transaction with the
           financial terms of certain other transactions we deemed relevant; and

       (g) made such other analyses and examinations as we have deemed necessary
           or appropriate.

        We have assumed and relied upon, without assuming any responsibility for
    verification, the accuracy and completeness of all of the financial and
    other information provided to, discussed with or reviewed by or for us, or
    publicly available, for purposes of this opinion and have further relied
    upon the assurance of the management of the Company that they are not aware
    of any facts that would make such information inaccurate or misleading. We
    have neither made nor obtained any independent evaluations or appraisals of
    the assets or liabilities of the Company, nor have we conducted a physical
    inspection of the properties or facilities of the Company. We have assumed
    that the financial forecasts provided to or discussed with us by the Company
    have been reasonably determined on bases reflecting the best currently
    available estimates and judgments of the management of the Company as to the
    future financial performance of the Company. We express no view as to such
    forecast or projection information or the assumptions on which they were
    based.

        For purposes of rendering our opinion, we have assumed that, in all
    respects material to our analysis, the representations and warranties of
    each party contained in the Agreement are true and correct, that each party
    will perform all of the covenants and agreements required to be performed by
    it under the Agreement and that all conditions to the consummation of the
    Tender Offer and the Merger will be satisfied without waiver thereof. We
    have also assumed that the definitive Agreement will not differ in any
    material respects from the draft thereof furnished to us.

        Our opinion herein is necessarily based on market, economic and other
    conditions as they exist and can be evaluated on the date of this letter.
    Our opinion is limited to the fairness, from a financial point of view, to
    the holders of the Company Shares of the Consideration, and we express no
    opinion as to the merits of the underlying decision by the Company to engage
    in the Transaction. Our opinion does not constitute a recommendation to any
    holder of the Company Shares as to whether such holder should tender any
    Company Shares pursuant to the Tender Offer or how such holder should vote
    on the proposed Merger or any matter related thereto.

        Chase Securities Inc., as part of its financial advisory business, is
    continually engaged in the valuation of businesses and their securities in
    connection with mergers and acquisitions and valuations for estate,
    corporate and other purposes. We have acted as financial advisor to the
    Company in connection with the Transaction and will receive a fee for our
    services, payment of a portion of which is contingent upon delivery of this
    letter and payment of a significant portion of which is contingent upon the
    consummation of the Tender Offer. In addition, the Company has agreed to
    indemnify us for certain liabilities arising out of our engagement. The
    Chase Manhattan Corporation and its affiliates, including Chase
    Securities Inc., in the ordinary course of business, have from time to time,
    provided investment banking services to the Company and commercial banking
    services to the Acquiror and its affiliates, for which we received usual and
    customary compensation, and in the future may continue to provide such
    services. We have acted as financial advisor to the Company in connection
    with the pending sale of the Company's contact lens sales

                                       2
<PAGE>
    and distribution business. In the ordinary course of business, we or our
    affiliates may trade in the debt and equity securities of the Company and
    the Acquiror and its affiliates for our own accounts and for the accounts of
    our customers and, accordingly, may at any time hold a long or short
    position in such securities.

        Based upon and subject to the foregoing, we are of the opinion that, as
    of the date hereof, the Consideration to be received by the holders of the
    Company Shares pursuant to the Transaction is fair, from a financial point
    of view, to such holders.

        This opinion is for the use and benefit of the Board of Directors of the
    Company in its evaluation of the Transaction and, except as set forth below,
    shall not be used for any other purpose without the prior written consent of
    Chase Securities Inc. This opinion shall not be reproduced, disseminated,
    quoted, summarized or referred to at any time, in any manner or for any
    purpose, nor shall any public references to Chase Securities Inc. be made by
    the Company, without the prior written consent of Chase Securities Inc.,
    except that a copy of this opinion may be included in its entirety in any
    proxy statement or Solicitation/Recommendation Statement on Schedule 14D-9
    with respect to the Transaction.

                                          Very truly yours,
                                          CHASE SECURITIES INC.

                           MASSACHUSETTS GENERAL LAWS
                     BUSINESS CORPORATION LAW CHAPTER 156B
                                   APPRAISAL

SECTION 86  SECTIONS APPLICABLE TO APPRAISAL; PREREQUISITES.

    If a corporation proposes to take a corporate action as to which any section
of this chapter provides that a stockholder who objects to such action shall
have the right to demand payment for his shares and an appraisal thereof,
sections eighty-seven to ninety-eight, inclusive, shall apply except as
otherwise specifically provided in any section of this chapter. Except as
provided in sections eighty-two and eighty-three, no stockholder shall have such
right unless (1) he files with the corporation before the taking of the vote of
the shareholders on such corporate action, written objection to the proposed
action stating that he intends to demand payment for his shares if the action is
taken and (2) his shares are not voted in favor of the proposed action.

SECTION 87  STATEMENT OF RIGHTS OF OBJECTING STOCKHOLDERS IN NOTICE OF MEETING;
            FORM.

    The notice of the meeting of stockholders at which the approval of such
proposed action is to be considered shall contain a statement of the rights of
objecting stockholders. The giving of such notice shall not be deemed to create
any rights in any stockholder receiving the same to demand payment for his
stock, and the directors may authorize the inclusion in any such notice of a
statement of opinion by the management as to the existence or non-existence of
the right of the stockholders to demand payment for their stock on account of
the proposed corporate action. The notice may be in such form as the directors
or officers calling the meeting deem advisable, but the following form of notice
shall be sufficient to comply with this section:

    "If the action proposed is approved by the stockholders at the meeting and
effected by the corporation, any stockholder (1) who files with the corporation
before the taking of the vote on the approval of such action, written objection
to the proposed action stating that he intends to demand payment for his shares
if the action is taken and (2) whose shares are not voted in favor of such
action has or may have the right to demand in writing from the corporation (or,
in the case of a consolidation or merger, the name of the resulting or surviving
corporation shall be inserted), within twenty days after the date of mailing to
him of notice in writing that the corporate action has become effective, payment
for his shares and an appraisal of the value thereof. Such corporation and any
such stockholder shall in such cases have the rights and duties and shall follow
the procedure set forth in sections 88 to 98, inclusive, of chapter 156B of the
General Laws of Massachusetts".

SECTION 88  NOTICE OF EFFECTIVENESS OF ACTION OBJECTED TO

    The corporation taking such action, or in the case of a merger or
consolidation the surviving or resulting corporation, shall, within ten days
after the date on which such corporate action became effective, notify each
stockholder who filed a written objection meeting the requirements of section
eighty-six and whose shares were not voted in favor of the approval of such
action, that the action approved at the meeting of the corporation of which he
is a stockholder has become effective. The giving of such notice shall not be
deemed to create any rights in any stockholder receiving the same to demand
payment for his stock. The notice shall be sent by registered or certified mail,
addressed to the stockholder at his last known address as it appears in the
records of the corporation.

SECTION 89  DEMAND FOR PAYMENT; TIME FOR PAYMENT

    If within twenty days after the date of mailing of a notice under subsection
(e) of section eighty-two, subsection (f) of section eighty-three, or section
eighty-eight, any stockholder to whom the
<PAGE>
corporation was required to give such notice shall demand in writing from the
corporation taking such action, or in the case of a consolidation or merger from
the resulting or surviving corporation, payment for his stock, the corporation
upon which such demand is made shall pay to him the fair value of his stock
within thirty days after the expiration of the period during which such demand
may be made.

SECTION 90  DEMAND FOR DETERMINATION OF VALUE; BILL IN EQUITY; VENUE

    If during the period of thirty days provided for in section eighty-nine the
corporation upon which such demand is made and any such objecting stockholder
fail to agree as to the value of such stock, such corporation or any such
stockholder may within four months after the expiration of such thirty-day
period demand a determination of the value of the stock of all such objecting
stockholders by a bill in equity filed in the superior court in the county where
the corporation in which such objecting stockholder held stock had or has its
principal office in the commonwealth.

SECTION 91  PARTIES TO SUIT TO DETERMINE VALUE; SERVICE

    If the bill is filed by the corporation, it shall name as parties respondent
all stockholders who have demanded payment for their shares and with whom the
corporation has not reached agreement as to the value thereof. If the bill is
filed by a stockholder, he shall bring the bill in his own behalf and in behalf
of all other stockholders who have demanded payment for their shares and with
whom the corporation has not reached agreement as to the value thereof, and
service of the bill shall be made upon the corporation by subpoena with a copy
of the bill annexed. The corporation shall file with its answer a duly verified
list of all such other stockholders, and such stockholders shall thereupon be
deemed to have been added as parties to the bill. The corporation shall give
notice in such form and returnable on such date as the court shall order to each
stockholder party to the bill by registered or certified mail, addressed to the
last known address of such stockholder as shown in the records of the
corporation, and the court may order such additional notice by publication or
otherwise as it deems advisable. Each stockholder who makes demand as provided
in section eighty-nine shall be deemed to have consented to the provisions of
this section relating to notice, and the giving of notice by the corporation to
any such stockholder in compliance with the order of the court shall be a
sufficient service of process on him. Failure to give notice to any stockholder
making demand shall not invalidate the proceedings as to other stockholders to
whom notice was properly given, and the court may at any time before the entry
of a final decree make supplementary orders of notice.

SECTION 92  DECREE DETERMINING VALUE AND ORDERING PAYMENT; VALUATION DATE

    After hearing the court shall enter a decree determining the fair value of
the stock of those stockholders who have become entitled to the valuation of and
payment for their shares, and shall order the corporation to make payment of
such value, together with interest, if any, as hereinafter provided, to the
stockholders entitled thereto upon the transfer by them to the corporation of
the certificates representing such stock if certificated or if uncertificated,
upon receipt of an instruction transferring such stock to the corporation. For
this purpose, the value of the shares shall be determined as of the day
preceding the date of the vote approving the proposed corporate action and shall
be exclusive of any element of value arising from the expectation or
accomplishment of the proposed corporate action.

SECTION 93  REFERENCE TO SPECIAL MASTER

    The court in its discretion may refer the bill or any question arising
thereunder to a special master to hear the parties, make findings and report the
same to the court, all in accordance with the usual practice in suits in equity
in the superior court.

                                       2
<PAGE>
SECTION 94  NOTATION ON STOCK CERTIFICATES OF PENDENCY OF BILL

    On motion the court may order stockholder parties to the bill to submit
their certificates of stock to the corporation for the notation thereon of the
pendency of the bill, and may order the corporation to note such pendency in its
records with respect to any uncertificated shares held by such stockholder
parties, and may on motion dismiss the bill as to any stockholder who fails to
comply with such order.

SECTION 95  COSTS; INTEREST

    The costs of the bill, including the reasonable compensation and expenses of
any master appointed by the court, but exclusive of fees of counsel or of
experts retained by any party, shall be determined by the court and taxed upon
the parties to the bill, or any of them, in such manner as appears to be
equitable, except that all costs of giving notice to stockholders as provided in
this chapter shall be paid by the corporation. Interest shall be paid upon any
award from the date of the vote approving the proposed corporate action, and the
court may on application of any interested party determine the amount of
interest to be paid in the case of any stockholder.

SECTION 96  DIVIDENDS AND VOTING RIGHTS AFTER DEMAND FOR PAYMENT

    Any stockholder who has demanded payment for his stock as provided in this
chapter shall not thereafter be entitled to notice of any meeting of
stockholders or to vote such stock for any purpose and shall not be entitled to
the payment of dividends or other distribution on the stock (except dividends or
other distributions payable to stockholders of record at a date which is prior
to the date of the vote approving the proposed corporate action) unless:

    (1) A bill shall not be filed within the time provided in section ninety;

    (2) A bill, if filed, shall be dismissed as to such stockholder; or

    (3) Such stockholder shall with the written approval of the corporation, or
       in the case of a consolidation or merger, the resulting or surviving
       corporation, deliver to it a written withdrawal of his objections to and
       an acceptance of such corporate action.

    Notwithstanding the provisions of clauses (1) to (3), inclusive, said
stockholder shall have only the rights of a stockholder who did not so demand
payment for his stock as provided in this chapter.

SECTION 97  STATUS OF SHARES PAID FOR

    The shares of the corporation paid for by the corporation pursuant to the
provisions of this chapter shall have the status of treasury stock, or in the
case of a consolidation or merger the shares or the securities of the resulting
or surviving corporation into which the shares of such objecting stockholder
would have been converted had he not objected to such consolidation or merger
shall have the status of treasury stock or securities.

SECTION 98  EXCLUSIVE REMEDY; EXCEPTION

    The enforcement by a stockholder of his right to receive payment for his
shares in the manner provided in this chapter shall be an exclusive remedy
except that this chapter shall not exclude the right of such stockholder to
bring or maintain an appropriate proceeding to obtain relief on the ground that
such corporate action will be or is illegal or fraudulent as to him.
