                             ITEM 5: OTHER EVENTS.

1.   Counterclaim by VISX Incorporated.
     --------------------------------- 

     On September 24, 1998, VISX, Incorporated ("VISX") filed a patent
infringement counterclaim in Autonomous Technologies Corporation's (the
"Company") October 1996 lawsuit in the United States District Court for the
District of Delaware (Civil Action No. 96-515) in which the Company is seeking a
declaratory judgment of non-infringement.  VISX is seeking injunctive relief to
prevent the Company from manufacturing, promoting and selling infringing
equipment in the U.S.  The Company does not believe it infringes on the two
patents named in the counterclaim.

     Summit Technology, Inc. ("Summit") has a royalty-free cross license with
VISX which, by the terms of the cross license, applies to wholly owned
subsidiaries of Summit.  The Company believes the claims of the Company and VISX
relating to alleged infringement of the VISX patents as to the manufacture, use,
sale or placement of the LADARVision System after the proposed merger with
Summit will become moot.

2.   Acquisition of the Company, Subject to Shareholder Approval.
     ----------------------------------------------------------- 

     The following is a brief summary of the terms of the Agreement and Plan of
Merger and is qualified in its entirety by reference to the Agreement and Plan
of Merger, dated October 1, 1998, filed herewith as Exhibit 10.1.

     On October 1, 1998, the Company entered into an Agreement and Plan of
Merger that provides for its merger with and into a wholly owned subsidiary of 
Summit Technology, Inc. ("Summit"). The merger transaction is subject to the 
approval of the stockholders of both the Company and Summit.

     The merger consideration is 11,650,400 shares of Summit stock and an 
equivalent amount of cash, subject to a maximum of $50 million in cash. This 
consideration will be divided among the outstanding shares of Autonomous common 
stock, the outstanding shares of Autonomous Series I Preferred Stock and options
and warrants for Autonomous common stock. Assuming a Summit stock price of
$4.00, the transaction has a total value of approximately $87 million, or
approximately $6.25 per fully diluted Autonomous share. Autonomous common
stockholders will receive part stock and part cash for their Autonomous shares.
The exact value, and the relative mix of cash and Summit stock, will vary
depending on the market price of Summit stock prior to the closing, the amount
of the loan to Autonomous described below and whether the holders of Series I
Preferred Stock exercise their right to redeem their shares for cash. A copy of
the Company's press release announcing the merger agreement is filed herewith as
Exhibit 99.1.

     Randy W. Frey, Chairman, President and Chief Executive Officer of the 
Company and CIBA Vision Group Management, Inc., together owning approximately 
21% of the Company's outstanding shares, and each of the Company's officers and 
directors have agreed to vote, as shareholders, for the merger.

     In connection with the merger agreement, Summit agreed to lend up to $5
million to the Company on a revolving credit basis. Under the revolving credit
agreement, the Company may not draw more than $1.5 million per month. One half
of the amount borrowed by the Company as of the closing date will reduce the
amount of the aggregate cash consideration in the merger. No use has been made
of this revolving credit facility as of the date of this filing. In the event
the merger does not occur through no fault of the Company, the amount drawn on
the revolving credit facility is due and payable 180 days from the date of the
termination of the merger agreement. A copy of the Letter Agreement re:
Revolving Credit Line, dated October 1, 1998, is filed herewith as Exhibit 10.2.

     Summit will file a registration statement on Form S-4 with the Securities
and Exchange Commission in connection with the shares of Summit stock to be
issued to the Company's shareholders.  Upon the effectiveness of this
registration statement, the Company and Summit plan to distribute a joint proxy
statement to their respective shareholders.

                                       2
<PAGE>
 
     Depending on the timing of the effectiveness of the registration statement
and other factors, the Company and Summit plan to hold their respective
shareholder meetings as soon as practicable, with the earliest date being in
December 1998 and the most likely date being in the middle of January 1999.

3.   Management Changes.
     ------------------ 

     On September 30, 1998, the Company and Dr. Richard Capozza agreed that Dr.
Capozza, as a result of the pending merger with Summit, has decided to pursue
other interests.  Dr. Capozza was a valuable employee and played a key role in
the development and progress of the Company over the past three years.  Dr.
Capozza's future contributions will be missed.  Dr. Capozza resigned as
President and as a director, effective September 30, 1998.

     Mr. Randy W. Frey, Chairman and Chief Executive Officer, resumed the
title of President effective October 1, 1998. On October 1, 1998, Dr. Charline
A. Gauthier, O.D., Ph.D., was named Vice President and Chief Operating Officer
of the Company. Dr. Gauthier previously was the Company's Vice President of
Clinical and Regulatory Affairs.



This Current Report on Form 8-K contains forward-looking statements within the
meaning of section 27A of the Securities Act of 1933 and Section 21E of the
Securities Exchange Act of 1934. Statements containing terms such as "believes,"
"does not believe," "no reason to believe," "expects," "plans," "intends,"
"estimates," or "anticipates" are considered to contain uncertainty and are
forward-looking statements.  Actual results could differ materially from those
projected in the forward-looking statements as a result of a number of important
factors, including: a decline in the price of Summit stock prior to the closing;
that there are no assurances the shareholders of both companies will take the
necessary actions to effectuate the transaction; that competitive responses may
occur preventing the achievement of increased market share; and the uncertainty
of the outcome of the Delaware lawsuit and the resources required to maintain
the Delaware lawsuit.  For a discussion of the other important factors that
could affect the Company's results, please refer to the Overview section, the
Management's Discussion and Analysis of Financial Condition and Results of
Operations, and the Risk Factors section in the Company's Annual Report on Form
10-K as amended.

                         AGREEMENT AND PLAN OF MERGER

   AGREEMENT AND PLAN OF MERGER, dated as of October 1, 1998 (this "AGREEMENT"),
among Summit Technology, Inc., a Massachusetts corporation ("PARENT"), Alpine
Acquisition Corp., a Delaware corporation and a wholly-owned subsidiary of
Parent ("MERGER SUB"), and Autonomous Technologies Corporation, a Florida
corporation (the "COMPANY").

                                  WITNESSETH:

   WHEREAS, the Boards of Directors of Parent, Merger Sub and the Company have
each determined that it is advisable and in the best interests of their
respective stockholders for Parent to enter into a business combination with the
Company upon the terms and subject to the conditions set forth herein;

   WHEREAS, in furtherance of such combination, the Boards of Directors of
Parent, Merger Sub and the Company have each approved the merger (the "MERGER")
of the Company with and into Merger Sub or, if the Merger is restructured as
provided herein, of Merger Sub with an into the Company, in accordance with the
applicable provisions of the Florida Business Corporation Act (the "FBCA") and
the Delaware General Corporation Law (the "DGCL"), and upon the terms and
subject to the conditions set forth herein;

   WHEREAS, Parent, Merger Sub and the Company intend, unless the Merger shall
have been restructured as provided herein, by approving resolutions authorizing
this Agreement, to adopt this Agreement as a plan of reorganization within the
meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended (the
"CODE"), and the regulations promulgated thereunder; and

   WHEREAS, pursuant to the Merger, each outstanding share (a "SHARE") of the
Company's common stock, $.01 par value per share (the "COMPANY COMMON STOCK"),
shall be converted into the right to receive the Merger Consideration (as
defined in Section 1.7(b)), upon the terms and subject to the conditions set
forth herein;

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

                                   ARTICLE I

                                  THE MERGER

   SECTION 1.1  The Merger.

   (a)  Effective Time.  At the Effective Time (as defined in Section 1.2), and
subject to and upon the terms and conditions of this Agreement, the FBCA and the
DGCL, the Company shall be merged with and into Merger Sub, the separate
corporate existence of the Company shall cease, and Merger 
<PAGE>
 
Sub shall continue as the surviving corporation. Merger Sub as the surviving
corporation after the Merger is hereinafter sometimes referred to as the
"SURVIVING CORPORATION."

   (b)  Closing.  Unless this Agreement shall have been terminated pursuant to
Section 7.1 and subject to the satisfaction or waiver of the conditions set
forth in Article VI, the consummation of the Merger (the "CLOSING") will take
place as promptly as practicable (and in any event within two business days)
after satisfaction or waiver of the conditions set forth in Article VI, at the
offices of Ropes & Gray, One International Place, Boston, Massachusetts, unless
another date, time or place is agreed to in writing by the parties hereto.

   SECTION 1.2  Effective Time.  As promptly as practicable after the
satisfaction or waiver of the conditions set forth in Article VI, the parties
hereto shall cause the Merger to be consummated by filing certificates of merger
as contemplated by the FBCA and the DGCL (the "CERTIFICATES OF MERGER"),
together with any required related certificates, with the Secretary of State of
the State of Florida and the Secretary of State of the State of Delaware, in
such form as required by, and executed in accordance with the relevant
provisions of, the FBCA and the DGCL (the time of the  later of such filings
being the "EFFECTIVE TIME").

   SECTION 1.3  Effect of the Merger.  At the Effective Time, the effect of the
Merger shall be as provided in this Agreement, the Certificates of Merger and
the applicable provisions of the FBCA and the DGCL.  Without limiting the
generality of the foregoing, and subject thereto, at the Effective Time all the
property, rights, privileges, powers and franchises of the Company and Merger
Sub shall vest in the Surviving Corporation, and all debts, liabilities and
duties of the Company and Merger Sub shall become the debts, liabilities and
duties of the Surviving Corporation.

   SECTION 1.4  Certificate of Incorporation, By-Laws.

   (a)  Certificate of Incorporation.  Unless otherwise determined by Parent
prior to the Effective Time, at the Effective Time the Certificate of
Incorporation of Merger Sub, as in effect immediately prior to the Effective
Time, shall be the Certificate of Incorporation of the Surviving Corporation
until thereafter amended in accordance with the DGCL and such Certificate of
Incorporation.

   (b)  By-Laws. Unless otherwise determined by Parent prior to the Effective
Time, at the Effective Time the By-Laws of Merger Sub, as in effect immediately
prior to the Effective Time, shall be the By-Laws of the Surviving Corporation
until thereafter amended in accordance with the DGCL, the Certificate of
Incorporation of the Surviving Corporation and such By-Laws.

   SECTION 1.5  Directors and Officers.  The directors of Merger Sub immediately
prior to the Effective Time shall be the initial directors of the Surviving
Corporation, each to hold office in accordance with the Certificate of
Incorporation and By-Laws of the Surviving Corporation, and the officers of
Merger Sub immediately prior to the Effective Time shall be the initial officers
of the Surviving Corporation, in each case until their respective successors are
duly elected or appointed and qualified.

                                      2-

   SECTION 1.6  Effect on Capital Stock.  At the Effective Time, by virtue of
the Merger and without any action on the part of the Parent, Merger Sub, the
Company or any of their respective stockholders:

   (a)  Conversion of Securities. Each Share issued and outstanding immediately
prior to the Effective Time (excluding any Shares to be canceled pursuant to
Section 1.6(b)) shall be converted, subject to Section 1.6(f), into the right to
receive (i) the quotient of 11,650,400 shares (the "STOCK CONSIDERATION") of
validly issued, fully paid and nonassessable shares ("PARENT SHARES") of the
Common Stock, $0.01 par value per share, of Parent ("PARENT COMMON STOCK")
divided by the Diluted Company Common Stock (the "PER SHARE STOCK
CONSIDERATION") and (ii) the quotient of $50,000,000 in cash less (A) one-half
of any amounts advanced to the Company by Parent after the date hereof and (B)
unless the holders of the Series I Preferred Stock shall have converted such
Series I Preferred Stock prior to the Effective Time, any amounts that would be
payable upon redemption of all shares of the Company's Convertible Preferred
Stock, Series I, $.01 par value per share (the "SERIES I PREFERRED STOCK"), that
are issued or issuable as of the date hereof, assuming redemption is made on the
date on which the Effective Time occurs in accordance with the provisions of the
Company's Articles of Incorporation or pursuant to any agreement with the
holders of Series I Preferred Stock prior to the Effective Time (the "CASH
CONSIDERATION") divided by the Diluted Company Common Stock (the "PER SHARE CASH
CONSIDERATION"). If the average closing price of Parent Common Stock on The
Nasdaq National Market for the five trading days ending on the day before the
date on which the Effective Time occurs (the "AVERAGE CLOSING PRICE") is less
than $4.2917, then the $50,000,000 in the previous sentence shall be reduced to
11,650,400 multiplied by the Average Closing Price.

   "Diluted Company Common Stock" means the number of shares of Company Common
Stock outstanding at the Effective Time (the "Outstanding Company Common
Stock"), plus all shares of Company Common Stock issuable upon the exercise or
conversion of all options, warrants, convertible securities or other rights,
agreements, arrangements or other commitments of any character pursuant to which
the Company is obligated, contingently or otherwise, to issue or sell shares of
Company Common Stock (excluding the Series I Preferred Stock and all rights to
acquire the Series I Preferred Stock) calculated by applying the treasury stock
method to options, warrants and convertible securities.

   (b)  Cancellation.  Each Share held in the treasury of the Company and each
Share owned by Parent, Merger Sub or any direct or indirect wholly owned
subsidiary of the Company or Parent immediately prior to the Effective Time
shall, by virtue of the Merger and without any action on the part of the holder
thereof, cease to be outstanding, be canceled and retired without payment of any
consideration therefor and cease to exist.

                                      3-

   (c) Stock Options and Stock Purchase Plan.

       (i)   At the Effective Time, Parent will assume each then outstanding
   option to purchase Shares (the "STOCK OPTIONS") under the Company's 1995
   Stock Option Plan (the "COMPANY STOCK OPTION PLAN") as to which the holder
   has waived the acceleration of vesting under Section 14 of the Company Stock
   Option Plan, and each such Stock Option shall thereafter constitute an option
   to acquire, on substantially the same terms and subject to substantially the
   same conditions as were applicable under such Stock Option, including without
   limitation term, vesting, exercisability, status as an "incentive stock
   option" under Section 422 of the Code and termination provisions, the number
   of shares of Parent Common Stock, rounded down to the nearest whole share,
   equal to the sum of (i) the product of the number of Shares subject to such
   Stock Option immediately prior to the Effective Time multiplied by the Per
   Share Stock Consideration plus (ii) the product of the number of Shares
   subject to such Stock Option immediately prior to the Effective Time
   multiplied by a fraction the numerator of which is the Per Share Cash
   Consideration and the denominator of which is the Average Closing Price.  The
   exercise price per share of Parent Common Stock (increased to the nearest
   whole cent) shall be equal to the aggregate exercise price of the Stock
   Option divided by the number of Shares of Parent Common Stock into which such
   Stock Option will become exercisable at the Effective Time; provided,
   however, that in the case of any Stock Option to which Section 421 of the
   Code applies by reason of its qualification as an incentive stock option
   under Section 422 of the Code, the conversion formula shall be adjusted if
   necessary to comply with Section 424(a) of the Code.

       (ii)  The Company shall use its best efforts to obtain all necessary
   waivers, consents or releases from holders of Stock Options under the Company
   Stock Option Plan and take any such other action as may be reasonably
   necessary to give effect to the transactions contemplated by this Section
   1.6(c).

       (iii) Parent shall take all corporate action necessary to reserve for
   issuance a sufficient number of Parent Shares for delivery pursuant to the
   terms set forth in this Section 1.6(c).

       (iv)  Subject to any applicable limitations under the Securities Act of
   1933, as amended, and the rules and regulations thereunder (the "SECURITIES
   ACT"), Parent shall either (A) file a Registration Statement on Form S-8 (or
   any successor form), effective as of the Effective Time, with respect to the
   shares of Parent Common Stock issuable upon exercise of the Stock Options, or
   (B) file any necessary amendments to the Company's previously-filed
   Registration Statement(s) on Form S-8 in order that the Parent will be deemed
   a "successor registrant" thereunder, and, in either event the Parent shall
   use all reasonable efforts to maintain the effectiveness of such registration
   statement(s) (and maintain the current status of the prospectus or
   prospectuses relating thereto) for so long as such Stock Options shall remain
   outstanding.

                                      4-
<PAGE>
 
       (v)  The Company will promptly cause written notice of the execution of
   this Agreement to be given to persons holding options or other rights to
   purchase Company Common Stock under the Company's 1996 Employee Stock
   Purchase Plan (the "COMPANY STOCK PURCHASE PLAN").  The Company will
   terminate the Company Stock Purchase Plan at the end of the current purchase
   period.

   (d) Capital Stock of Merger Sub. Each share of common stock, $.01 par value,
of Merger Sub issued and outstanding immediately prior to the Effective Time
shall remain outstanding.

   (e) Adjustments to Stock Consideration. The Stock Consideration shall be
adjusted to fully reflect the effect of any stock split, reverse split, stock
dividend (including any dividend or distribution of securities convertible into
Parent Common Stock), reorganization, recapitalization or other like change with
respect to Parent Common Stock occurring after the date hereof and prior to the
Effective Time.

   (f) Fractional Shares. Unless Parent otherwise elects, no certificates or
scrip representing less than one Parent Share shall be issued upon the surrender
for exchange of a certificate or certificates which immediately prior to the
Effective Time represented outstanding Shares (the "CERTIFICATES"). If Parent so
elects, in lieu of any such fractional share, each holder of Shares who would
otherwise have been entitled to a fraction of a Parent Share upon surrender of
Certificates for exchange shall be paid upon such surrender cash equal to the
product of (i) such fraction, multiplied by (ii) the Average Closing Price.

   SECTION 1.7  Exchange of Certificates.

   (a) Exchange Agent. Parent shall supply, or shall cause to be supplied, to or
for the account of BankBoston, N.A., or such other bank or trust company as
shall be designated by Parent (the "EXCHANGE AGENT"), in trust for the benefit
of the holders of Company Common Stock, for exchange in accordance with this
Section 1.7, through the Exchange Agent, certificates evidencing the Parent
Shares issuable pursuant to Section 1.6 in exchange for outstanding Shares.

   (b) Exchange Procedures. As soon as reasonably practicable after the
Effective Time, Parent will instruct the Exchange Agent to mail to each holder
of record of Certificates (i) a letter of transmittal (which shall specify that
delivery shall be effected, and risk of loss and title to the Certificates shall
pass, only upon proper delivery of the Certificates to the Exchange Agent and
shall be in such form and have such other provisions as Parent may reasonably
specify), and (ii) instructions to effect the surrender of the Certificates in
exchange for the certificates evidencing Parent Shares. Upon surrender of a
Certificate for cancellation to the Exchange Agent together with such letter of
transmittal, duly executed, and such other customary documents as may be
required pursuant to such instructions, the holder of such Certificate shall be
entitled to receive in exchange therefor (A) certificates evidencing that number
of whole Parent Shares which such holder has the right to receive pursuant to
Section 1.6(a) in respect of the Shares formerly evidenced by such Certificate,
(b) the per Share Cash Consideration, (C) any dividends or other distributions
to which
                                       5-
<PAGE>
 
such holder is entitled pursuant to Section 1.7(c), and (D) cash in respect of
fractional shares as provided in Section 1.6(f) (the Stock Consideration, the
Cash Consideration, dividends, distributions and cash being, collectively, the
"MERGER CONSIDERATION"), and the Certificate so surrendered shall forthwith be
canceled. In the event of a transfer of ownership of Shares which is not
registered in the transfer records of the Company as of the Effective Time, the
Merger Consideration may be issued and paid in accordance with this Article I to
a transferee if the Certificate evidencing such Shares is presented to the
Exchange Agent, accompanied by all documents required to evidence and effect
such transfer pursuant to this Section 1.7(b) and by evidence that any
applicable stock transfer taxes have been paid. Until so surrendered, each
outstanding Certificate that, prior to the Effective Time, represented Shares
will be deemed from and after the Effective Time, for all corporate purposes,
other than the payment of dividends and subject to Section 1.6(f), to evidence
the ownership of the number of whole Parent Shares that represent the Stock
Consideration with respect to such Shares.

   (c) Distributions With Respect to Unexchanged Parent Shares. No dividends or
other distributions declared or made after the Effective Time with respect to
Parent Shares with a record date after the Effective Time shall be paid to the
holder of any unsurrendered Certificate with respect to the Parent Shares they
are entitled to receive until the holder of such Certificate shall surrender
such Certificate. Subject to applicable law, following surrender of any such
Certificate, there shall be paid to the record holder of the certificates
representing whole Parent Shares issued in exchange therefor, without interest,
at the time of such surrender, the amount of dividends or other distributions
with a record date after the Effective Time theretofore paid with respect to
such whole Parent Shares.

   (d) Transfers of Ownership. If any certificate for Parent Shares is to be
issued in a name other than that in which the Certificate surrendered in
exchange therefor is registered, it will be a condition to the issuance thereof
that the Certificate so surrendered will be properly endorsed and otherwise in
proper form for transfer and that the person requesting such exchange will have
paid to Parent or any agent designated by it any transfer or other taxes
required by reason of the issuance of a certificate for Parent Shares in any
name other than that of the registered holder of the certificate surrendered, or
have established to the satisfaction of Parent or any agent designated by it
that such tax has been paid or is not payable.

   (e) No Liability. At any time following one year after the Effective Time,
Parent shall be entitled to require the Exchange Agent to deliver to Parent any
Merger Consideration which had been made available to the Exchange Agent by or
on behalf of Parent and which has not been disbursed to holders of Certificates,
and thereafter such holders shall be entitled to look to Parent only as general
creditors thereof with respect to the Merger Consideration payable upon due
surrender of their Certificates. Notwithstanding the foregoing, neither Parent,
Merger Sub nor the Company shall be liable to any holder of Company Common Stock
for any Merger Consideration delivered to a public official pursuant to any
applicable abandoned property, escheat or similar law.

                                      6-

this Agreement to any holder of Company Common Stock such amounts as Parent or
the Exchange Agent is required to deduct and withhold with respect to the making
of such payment under the Code, or any provision of state, local or foreign tax
law. To the extent that amounts are so withheld by Parent or the Exchange Agent,

Certificates shall have been lost, stolen or destroyed, the Exchange Agent shall
issue in exchange for such lost, stolen or destroyed Certificates, upon the

its discretion and as a condition precedent to the issuance thereof, require the
owner of such lost, stolen or destroyed Certificates to deliver a bond in such
sum as it may reasonably direct as indemnity against any claim that may be made
against Parent or the Exchange Agent with respect to the Certificates alleged to
have been lost, stolen or destroyed.

otherwise to take, and will take, all such lawful and necessary action.

is materially adverse to the business, assets (including intangible assets),

or Parent and its subsidiaries, as the case may be, in each case taken as a
whole (other than changes that are the effect of economic factors affecting the

except as set forth in the written disclosure schedule delivered on or prior to
the date hereof by the Company to Parent that is arranged in paragraphs
corresponding to the numbered and lettered paragraphs contained in this Article
II (the "COMPANY DISCLOSURE SCHEDULE"):

   SECTION 2.1 Organization and Qualification; Subsidiaries. Each of the Company
and each of its subsidiaries is a corporation duly organized, validly existing
and in good standing under the laws of the jurisdiction of its incorporation and

<PAGE>
 
it purports to own, operate or lease and to carry on its business as it is now
being conducted, except where the failure to be so organized, existing and in
good standing or to have such power, authority and Approvals would not
reasonably be expected to have a Company Material Adverse Effect. Each of the
Company and its subsidiaries is duly qualified or licensed as a foreign
corporation to do business, and is in good standing, in each jurisdiction where
the character of its properties owned, leased or operated by it or the nature of
its activities makes such qualification or licensing necessary, except for such
failures to be so duly qualified or licensed and in good standing that would not
reasonably be expected to have a Company Material Adverse Effect. A true and
complete list as of the date hereof of all of the Company's subsidiaries,
together with the jurisdiction of incorporation of each subsidiary, the
authorized capitalization of each subsidiary, and the percentage of each
subsidiary's outstanding capital stock owned by the Company or another
subsidiary, is set forth in Section 2.1 of the Company Disclosure Schedule. The
Company does not directly or indirectly own any equity or similar interest in,
or any interest convertible into or exchangeable or exercisable for, any equity
or similar interest in, any corporation, partnership, joint venture or other
business association or entity, with respect to which interest the Company has
invested or is required to invest $200,000 or more, excluding securities in any
publicly traded company held for investment by the Company and comprising less
than five percent of the outstanding stock of such company.

and By-Laws as most recently restated and subsequently amended to the date
hereof, and has furnished or made available to Parent the Articles of

its subsidiaries (the "SUBSIDIARY DOCUMENTS"). Such Articles of Incorporation,
By-Laws and Subsidiary Documents are in full force and effect and neither the
Company nor any of its subsidiaries is in violation of any of the provisions of
its Articles of Incorporation or By-Laws or Subsidiary Documents, except where
the failure to be in full force and effect or where such violation would not
have a Company Material Adverse Effect.

   SECTION 2.3 Capitalization. The authorized capital stock of the Company
consists of (i) 25,000,000 shares of Company Common Stock and (ii) 1,000,000
shares of preferred stock, $0.01 par value per share. As of October 1, 1998, (i)

shares of Series I Preferred Stock, (v) 922,350 shares of Company Common Stock
were reserved for issuance upon the exercise of outstanding warrants, (vi)
1,690,926 shares of Company Common Stock were

                                      10-

(viii) 380,000 of Company Common Stock are reserved for issuance pursuant to
stock purchase warrants which may become outstanding upon the exercise of an

sentence. No material change in such capitalization has occurred between
September 30, 1998 and the date hereof other than the issuance of shares of
Company Common Stock under the Company Stock Option Plans and under the Company
Stock Purchase Plan. All options, warrants or other rights, agreements,
arrangements or commitments of any character to which the Company or a
subsidiary or, to the Company's knowledge, any other person is a party relating

contingent or otherwise, of the Company or any of its subsidiaries to
repurchase, redeem or otherwise acquire any shares of Company Common Stock or
the capital stock of any subsidiary or to provide funds to or make any
investment (in the form of a loan, capital contribution, guaranty or otherwise)
in any such subsidiary or any other entity. All of the outstanding shares of
capital stock of each of the Company's subsidiaries are duly authorized, validly
issued, fully paid and nonassessable, and all such shares are owned by the
Company or another subsidiary of the Company, free and clear of all security
interests, liens, claims, pledges, agreements, limitations in the Company's
voting rights, charges or other encumbrances of any nature whatsoever
(collectively, "COMPANY LIENS").

   SECTION 2.4 Authority Relative to this Agreement. The Company has all
necessary corporate power and authority to execute and deliver this Agreement
and to perform its obligations hereunder and to consummate the transactions
contemplated hereby. The execution and delivery of this Agreement by the Company
and the consummation by the Company of the transactions contemplated hereby have
been duly and validly authorized by all necessary corporate action, and no other
corporate proceedings on the part of the Company are necessary to authorize this
Agreement or to consummate the transactions so contemplated (other than the
adoption of this Agreement by the holders of at least a majority of the
outstanding shares of Company Common Stock entitled to vote in accordance with
the FBCA and the Company's Articles of Incorporation and By-Laws). As of the
date of this Agreement, the Board of Directors of the Company has determined
that it is advisable and in the best interest of the Company's stockholders for
the Company to enter into a business combination with Parent upon the terms and
subject to the conditions of this Agreement, and has unanimously recommended
that the Company's stockholders approve and adopt this Agreement and the Merger.

to have a Company Material Adverse Effect; (b) neither the Company nor any of
its subsidiaries is a party to any collective bargaining agreement or other
labor union contract applicable to persons employed by the Company or its
subsidiaries; and (c) neither the Company nor any of its subsidiaries has any
knowledge of any strikes, slowdowns, work stoppages, lockouts, or threats

Material Adverse Effect.

   SECTION 2.13 Registration Statement, Joint Proxy Statement/Prospectus. The
information supplied by the Company for inclusion or incorporation by reference
in the Registration Statement (as defined in Section 3.13) shall not at the time
the Registration Statement is declared effective by the SEC 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 information
supplied by the Company for inclusion or incorporation by reference in the joint
proxy statement/prospectus to be sent to the stockholders of the Company in
connection with the meeting of the stockholders of the Company to consider the
Merger (the "COMPANY STOCKHOLDERS MEETING") and to be sent to the stockholders
of Parent in connection with the meeting of the stockholders of Parent to
consider the Merger (the "PARENT STOCKHOLDERS MEETING," and together with the
Company Stockholder Meeting, the "STOCKHOLDERS MEETINGS") (such joint proxy
statement/prospectus as amended or supplemented is referred to herein as the
"JOINT PROXY STATEMENT/PROSPECTUS"), will not, on the date the Joint Proxy
Statement/Prospectus (or any amendment thereof or supplement thereto) is first
mailed to stockholders, at the time of the Stockholders Meetings, or at the
Effective Time, contain any statement which, at such time and in light of the
circumstances under which it shall be made, is false

                                      16-

or misleading with respect to any material fact, or shall omit to state any
material fact necessary in order to make the statements made therein not false
or misleading, or omit to state any material fact necessary to correct any
statement in any earlier communication with respect to the solicitation of
proxies for the Stockholders Meetings which has become false or misleading. If
at any time prior to the Effective Time any event relating to the Company or any
of its respective affiliates, officers or directors should be discovered by the
Company which should be set forth in an amendment to the Registration Statement
or a supplement to the Joint Proxy Statement/Prospectus, the Company shall
promptly inform Parent and Merger Sub. Notwithstanding the foregoing, the
Company makes no representation or warranty with respect to any information
supplied by Parent or Merger Sub which is contained in or furnished in
connection with the preparation of the Registration Statement or the Joint Proxy
Statement/Prospectus.

   SECTION 2.14 Title to Property. Neither the Company nor any of its
subsidiaries owns any real property.

   SECTION 2.15 Taxes.

   (a) For purposes of this Agreement, "TAX" or "TAXES" shall mean taxes, fees,
levies, duties, tariffs, imposts, and governmental impositions or charges of any
kind in the nature of (or similar to) taxes, payable to any federal, state,
local or foreign taxing authority, including (without limitation) (i) income,
franchise, profits, gross receipts, ad valorem, net worth, value added, sales,
use, service, real or personal property, special assessments, capital stock,
license, payroll, withholding, employment, social security, workers'
compensation, unemployment compensation, utility, severance, production, excise,
stamp, occupation, premiums, windfall profits, transfer and gains taxes, and
(ii) interest, penalties, additional taxes and additions to tax imposed with
respect thereto; and "TAX RETURNS" shall mean returns, reports, and information
statements with respect to Taxes required to be filed with the IRS or any other
federal, foreign, state or provincial taxing authority, domestic or foreign,
including, without limitation, consolidated, combined and unitary tax returns.

   (b) (i) The Company and its subsidiaries have filed all Tax Returns required
to be filed by them, (ii) the Company and its subsidiaries have paid and
discharged all Taxes due in connection with or with respect to the periods or
transactions covered by such Tax Returns and have paid all other Taxes as are
due, except such as are being contested in good faith by appropriate proceedings
(to the extent that any such proceedings are required) and with respect to which
the Company is maintaining adequate reserves, and (iii) there are no other Taxes
that would be due if asserted by a taxing authority, except with respect to
which the Company is maintaining reserves to the extent currently required,
unless in the case of clauses (i), (ii) and (iii) above the failure to do so
would not reasonably be expected to have a Company Material Adverse Effect.
Except as does not involve or would not result in liability that would
reasonably be expected to have a Company Material Adverse Effect: (i) there are
no tax liens on any assets of the Company or any subsidiary thereof; and (ii)
neither the Company nor any of its subsidiaries has granted any waiver of any
statute of limitations with respect to, or any extension of a period for the
assessment of, any Tax. Neither the Company nor any of its subsidiaries has made
any payments, is obligated to make any payments, or is a party

                                      17-
<PAGE>
 
to any agreement that under any circumstance could obligate it to make any
payments that will not be deductible under Code Section 280G. None of the
Company and its subsidiaries (i) has been a member of an affiliated group filing
a consolidated federal income Tax Return (other than a group the common parent
of which was the Company) or (ii) has any liability for the Taxes of any other
person or entity (other than the Company and its subsidiaries) under Treas. Reg.
(S)1.1502-6 (or any similar provision of state, local or foreign law), as
transferee or successor, by contract or otherwise. Neither the Company nor any
subsidiary has consented at any time under Section 341(f)(1) of the Code to have
the provisions of Section 341(f)(2) of the Code apply to any disposition of the
assets of the Company or any subsidiary. The accruals and reserves for Taxes
(including deferred taxes) reflected in the 1998 Company Balance Sheet are in
all material respects adequate to cover all Taxes required to be accrued through
the date thereof (including interest and penalties, if any, thereon and Taxes
being contested) in accordance with generally accepted accounting principles.

   (c) Neither the Company nor any of its subsidiaries is, or has been, a United
States real property holding corporation (as defined in Section 897(c)(2) of the
Code) during the applicable period specified in Section 897(c)(1)(A)(ii) of the
Code. To the best knowledge of the Company, neither the Company nor any of its
subsidiaries owns any property of a character, the indirect transfer of which,
pursuant to this Agreement, would give rise to any material documentary, stamp
or other transfer tax.

   SECTION 2.16 Environmental Matters. Except in all cases as, in the aggregate,
have not had and would not reasonably be expected to have a Company Material
Adverse Effect, the Company and each of its subsidiaries: (i) have obtained all
Approvals which are required to be obtained under all applicable federal, state,
foreign or local laws or any regulation, code, plan, order, decree, judgment,
notice or demand letter issued, entered, promulgated or approved thereunder
relating to pollution or protection of the environment, including laws relating
to emissions, discharges, releases or threatened releases of pollutants,
contaminants, or hazardous or toxic materials or wastes into ambient air,
surface water, ground water, or land or otherwise relating to the manufacture,
processing, distribution, use, treatment, storage, disposal, transport, or
handling of pollutants, contaminants or hazardous or toxic materials or wastes
by the Company or its subsidiaries or their respective agents ("ENVIRONMENTAL
LAWS"); (ii) are in compliance with all terms and conditions of such required
Approvals, and also are in compliance with all other limitations, restrictions,
conditions, standards, prohibitions, requirements, obligations, schedules and
timetables contained in applicable Environmental Laws; (iii) have not received
notice of any past or present violations of Environmental Laws or any event,
condition, circumstance, activity, practice, incident, action or plan which is
reasonably likely to interfere with or prevent continued compliance with or
which would give rise to any common law or statutory liability, or otherwise
form the basis of any claim, action, suit or proceeding, against the Company or
any of its subsidiaries based on or resulting from the manufacture, processing,
distribution, use, treatment, storage, disposal, transport or handling, or the
emission, discharge or release into the environment, of any pollutant,
contaminant or hazardous or toxic material or waste; and (iv) have taken all
actions necessary under applicable Environmental Laws to register any products
or materials required to be registered by the Company or its subsidiaries (or
any of their respective agents) thereunder.

   SECTION 2.17 Intellectual Property.

   (a) The Company, directly or indirectly, owns, or is licensed or otherwise
possesses legally enforceable rights to use, all patents, trademarks, trade
names, service marks, copyrights, and any applications therefor, know-how,
computer software programs or applications, and tangible or intangible
proprietary information or material that are material to the business of the
Company and its subsidiaries, taken as a whole, as currently conducted or as
proposed to be conducted (the "COMPANY INTELLECTUAL PROPERTY RIGHTS"), except
where the failure to do so would not have a Company Material Adverse Effect.

   (b) The execution and delivery of this Agreement by the Company, and the
consummation of the transactions contemplated hereby, will neither cause the
Company or any of its subsidiaries to be in violation or default in any material
respect under any license, sublicense or agreement with respect to the Company
Intellectual Property Rights, nor entitle any other party to any such license,
sublicense or agreement to terminate or modify such license, sublicense or
agreement, except where such violation, default, termination or modification
would not reasonably be expected to have a Company Material Adverse Effect. No
claims have been asserted or, to the knowledge of the Company, are threatened by
any person nor are there any valid grounds, to the knowledge of the Company, for
any bona fide claims (i) against the use by the Company or any of its
subsidiaries of the Company Intellectual Property Rights, or (ii) challenging
the ownership by the Company or any of its subsidiaries, or the validity or
effectiveness of any of the Company Intellectual Property Rights, except for
such claims that would not, individually or in the aggregate, reasonably be
expected to have a Company Material Adverse Effect.

   (c) Neither the Company nor any of its subsidiaries has interfered with,
infringed upon, misappropriated, or otherwise come into conflict with any
Intellectual Property rights of third parties, and there has never been any
charge, complaint, claim, demand, or notice alleging any such interference,
infringement, misappropriation, or violation (including any claim that the
Company or one of its Subsidiaries must license or refrain from using any
Intellectual Property rights of any third party).

   (d) Section 2.17(d) of the Disclosure Schedule identifies each patent or
registration which has been issued to the Company or any of its subsidiaries
with respect to the Company Intellectual Property Rights, identifies each
pending patent application or application for registration which has been made
with respect to the Company Intellectual Property Rights, and identifies each
license, agreement, or other permission which the Company or any of its
subsidiaries have granted to any third party with respect to any of the Company
Intellectual Property Rights (together with any exceptions). The Company has
delivered to Parent correct and complete copies of all such patents,
registrations, applications, licenses, agreements, and permissions (as amended
to date) and has made available to Parent correct and complete copies of all
other written documentation evidencing ownership and prosecution (if applicable)
of each such item. The Company disclosed all relevant prior art in its patent
applications, and it has no reason to believe that any of its patents is invalid
or
                                      19-
<PAGE>
 
unenforceable. With respect to each item of Intellectual Property required to be
identified in (S) 2.17(d) of the Company Disclosure Schedule:

       (i) the Company and its subsidiaries possess all right, title, and
   interest in and to the item, free and clear of any Lien, license, or other
   restriction;

       (ii) the item is not subject to any outstanding injunction, judgment,
   order, decree, ruling, or charge;

       (iii) no action, suit, proceeding, hearing, investigation, charge,
   complaint, claim, or demand is pending or, to the knowledge of the Company,
   is threatened, which challenges the legality, validity, enforceability, use,
   or ownership of the item; and

       (iv) neither the Company nor any of its subsidiaries has agreed to
   indemnify any Person for or against any interference, infringement,
   misappropriation, or other conflict with respect to the item.

   SECTION 2.18 Regulatory Matters.

   (a) Since January 1, 1996 through the date hereof (i) there have been no
written notices, citations or decisions by any governmental or regulatory body
that any product produced, manufactured, marketed or distributed at any time by
the Company or any Company subsidiary (the "COMPANY PRODUCTS") is defective or
fails to meet any applicable standards promulgated by any such governmental or
regulatory body, or any other governmental or regulatory body, agency or office
of any other jurisdiction to which the Company or any of its subsidiaries is
subject, (ii) there have been no recalls, field notifications or seizures
ordered or threatened by the United States Food and Drug Administration (the
"FDA") or any other comparable governmental or regulatory body with respect to
any of the Company Products and (iii) none of the Company or the Company
subsidiaries have received any warning letter, Section 305 notices from the FDA
or so-called Section 483 notices of adverse observations (or comparable notices
from such other governmental or regulatory bodies).

   (b) Except as would not, individually or in the aggregate, have a Company
Material Adverse Effect, with respect to each Company Product: (i) the Company
and its subsidiaries have obtained all applicable approvals, clearances,
authorizations, licenses (including site licensures) and registrations required
by United States or foreign governments or government agencies to permit the
manufacturing, distribution, sale (including reimbursement and pricing),
marketing, export, import or human research (including clinical and non-clinical
trials) of such Product (collectively, "LICENSES"); and (ii) the Company and its
subsidiaries are in full compliance with all terms and conditions of each
License in each country in which such Company Product is marketed, and with all
requirements pertaining to the manufacturing (including current good
manufacturing practices), marketing, export, import or human research (including
good laboratory practices and clinical and non-clinical trials) of such Company
Product which is not required to be the subject of a License.

                                      20-
<PAGE>
 
   (c) There are no impediments to issuance of any Company FDA premarket
approval application ("PMA") as to which the Company has received an approvable
letter from the FDA other than those set forth in the so-called Section 483
Notices described in the Company Disclosure Schedule, and the Company is not
aware of any reason why it will be unable to address to the FDA's satisfaction
all observations contained in such Notices. The information in such PMAs is true
and correct in all material respects and the Company is not aware of any basis
upon which the FDA could fail to approve any material aspect of such
applications that have not yet received FDA approval.

   SECTION 2.19 Interested Party Transactions. Except for transactions described
in the Company SEC Reports filed prior to the date hereof, no event has occurred
that would be required to be reported as a Certain Relationship or Related
Transaction, pursuant to Item 404 of Regulation S-K promulgated by the SEC.

   SECTION 2.20 Insurance. All material fire and casualty, general liability,
business interruption, product liability, professional liability and sprinkler
and water damage insurance policies maintained by the Company or any of its
subsidiaries are with reputable insurance carriers, provide adequate coverage
for all normal risks incident to the business of the Company and its
subsidiaries, taken as a whole, and their properties and assets, and are in
character and amount customary for persons engaged in similar businesses and
subject to the same or similar perils or hazards, except for any such failures
to maintain insurance policies that, individually or in the aggregate, would not
reasonably be expected to have a Company Material Adverse Effect.

   SECTION 2.21 Opinion of Financial Advisor. The Company has been advised by
its financial advisor, EVEREN Securities, Inc. that in its opinion, as of the
date hereof, the Merger Consideration to be received by the holders of Shares in
the Merger is fair to the holders of Shares from a financial point of view.

   SECTION 2.22 Brokers. No broker, finder or investment banker (other than
EVEREN Securities, Inc., the fees and expenses of whom will be paid by the
Company) is entitled to any brokerage, finder's or other fee or commission in
connection with the transactions contemplated by this Agreement based upon
arrangements made by or on behalf of the Company or its subsidiaries or
affiliates. The Company has heretofore furnished to Parent a complete and
correct copy of all agreements between the Company and EVEREN Securities, Inc.
pursuant to which such firm would be entitled to any payment relating to the
transactions contemplated hereunder.

   SECTION 2.23 Change in Control Payments. Neither the Company nor any of its
subsidiaries have any plans, programs or agreements to which they are parties,
or to which they are subject, pursuant to which payments may be required or
acceleration of benefits may be required upon a change of control of the 
Company.

                                      21-

estimate and description of the expenses of the Company and its subsidiaries
which the Company expects to incur, or has incurred, in connection with the

   SECTION 2.26 Sections 607.0901 and 607.0902 of the FBCA Not Applicable. The
Board of Directors of the Company has taken all actions so that the restrictions
contained in Section 607.0901 of the FBCA applicable to an "affiliated
transaction" (as defined in Section 607.0901) and the restrictions contained in
Section 607.0902 will not apply to the execution, delivery or performance of
this Agreement or the respective Stockholder Agreements dated as of the date
hereof between Parent and certain stockholders of the Company (collectively, the
"STOCKHOLDERS AGREEMENTS") or the consummation of the Merger or the other
transactions contemplated by this Agreement or by the Stockholders Agreements.

                                  ARTICLE III

            REPRESENTATIONS AND WARRANTIES OF PARENT AND MERGER SUB

   Parent and Merger Sub hereby, jointly and severally, represent and warrant to
the Company that, except as set forth in the written disclosure schedule
delivered on or prior to the date hereof by Parent to the Company that is
arranged in paragraphs corresponding to the numbered and lettered paragraphs
contained in this Article III (the "PARENT DISCLOSURE SCHEDULE") or disclosed in
the Parent SEC Reports filed prior to the date hereof:

   SECTION 3.1 Organization and Qualification; Subsidiaries. Each of Parent and
its subsidiaries is a corporation duly organized, validly existing and in good
standing under the laws of the jurisdiction of its incorporation and has the
requisite corporate power and authority and is in possession of all Approvals
necessary to own, lease and operate the properties it purports to own, operate
or lease and to carry on its business as it is now being conducted, except where
the failure to be so organized, existing and in good standing or to have such
power, authority and Approvals would not reasonably be expected to have a Parent
Material Adverse Effect. Each of Parent and its subsidiaries is duly qualified
or licensed as a foreign corporation to do business, and is in good standing, in
each jurisdiction where the character of its properties owned, leased or
operated by it or the nature of its activities makes such qualification or
licensing necessary, except for such failures to be so duly qualified or
licensed and in good standing that would not reasonably be expected to have a
Parent Material Adverse Effect. A true and complete list as of the date hereof
of all of Parent's subsidiaries, together with the jurisdiction of incorporation
of each subsidiary and the percentage of each subsidiary's outstanding capital
stock owned by Parent or another subsidiary, is set forth in Section 3.1 of the
Parent Disclosure Schedule. Parent does not directly or indirectly own any
equity or similar interest in, or any interest convertible into or exchangeable
or exercisable for,
                                      22-
<PAGE>
 
any equity or similar interest in, any corporation, partnership, joint venture
or other business association or entity, with respect to which Parent has
invested or is required to invest $200,000 or more, excluding securities in any
publicly traded company held for investment by Parent and comprising less than
five percent of the outstanding capital stock of such company.

   SECTION 3.2 Charter and By-Laws. Parent has heretofore furnished to the
Company a complete and correct copy of its Articles of Organization and By-Laws,
as most recently restated and subsequently amended to the date hereof. Such
Articles of Organization and By-Laws are in full force and effect and neither
Parent nor Merger Sub is in violation of any of the provisions of its Articles
of Incorporation or By-Laws, except where the failure to be in full force and
effect or where such violation would not have a Parent Material Adverse Effect.

   SECTION 3.3 Capitalization. As of September 29, 1998, the authorized capital
stock of Parent consisted of (i) 60,000,000 shares of Parent Common Stock, of
which 31,153,765 shares were issued and outstanding, all of which are validly
issued, fully paid and non-assessable, 169,115 shares were held in treasury,
2,484,097 shares were reserved for future issuance under Parent's stock option
and employee stock purchase plans and (ii) 5,000,000 shares of preferred stock,
$.01 par value per share, none of which was issued and outstanding and none of
which was held in treasury. No material change in such capitalization has
occurred between September __, 1998 and the date hereof, except for issuance of
Parent Common Stock pursuant to Parent stock plans. All options, warrants or
other rights, agreements, arrangements or commitments of any character to which
Parent or a subsidiary or, to Parent's knowledge, any other person is a party
relating to the issued or unissued capital stock of Parent or any of its
subsidiaries or obligating Parent or any of its subsidiaries to issue or sell
any shares of capital stock of, or other equity interests in, Parent or any of
its subsidiaries are described in Section 3.3 of the Parent Disclosure Schedule.
There are no obligations, contingent or otherwise, of Parent or any of its
subsidiaries to repurchase, redeem or otherwise acquire any shares of Parent
Common Stock or the capital stock of any subsidiary or to provide funds to or
make any investment (in the form of a loan, capital contribution or otherwise)
in any such subsidiary other than guarantees of bank obligations of subsidiaries
entered into in the ordinary course of business. All of the outstanding shares
of capital stock of each of Parent's subsidiaries is duly authorized, validly
issued, fully paid and nonassessable and all such shares are owned by Parent or
another subsidiary of Parent, free and clear of all security interests, liens,
claims, pledges, agreements, limitations in Parent's voting rights, charges or
other encumbrances of any nature whatsoever (collectively, "PARENT LIENS").

   SECTION 3.4 Authority Relative to this Agreement. Each of Parent and Merger
Sub has all necessary corporate power and authority to execute and deliver this
Agreement and to perform its obligations hereunder and to consummate the
transactions contemplated hereby. The execution and delivery of this Agreement
by Parent and Merger Sub and the consummation by Parent and Merger Sub of the
transactions contemplated hereby have been duly and validly authorized by all
necessary corporate action on the part of Parent and Merger Sub, and no other
corporate proceedings on the part of Parent or Merger Sub are necessary to
authorize this Agreement or to consummate the transactions contemplated thereby
(other than the approval of the issuance of the Parent Common

                                      23-
<PAGE>
 
Stock by holders of a majority of the outstanding Parent Common Stock present or
represented by proxy and entitled to vote at the Parent Stockholders Meeting).
As of the date hereof, the Board of Directors of Parent has determined that it
is advisable and in the best interest of Parent's stockholders for Parent to
enter into a business combination with the Company upon the terms and subject to
the conditions of this Agreement and has unanimously recommended that the
stockholders of Parent approve the issuance of Parent Common Stock in the Merger
pursuant to this Agreement. This Agreement has been duly and validly executed
and delivered by Parent and Merger Sub and, assuming the due authorization,
execution and delivery by the Company, constitutes a legal, valid and binding
obligation of Parent and Merger Sub enforceable against each of them in
accordance with its terms.

   SECTION 3.5 No Conflict, Required Filings and Consents.

   (a) Section 3.5(a) of the Parent Disclosure Schedule includes a list as of
the date hereof of: (i) all contracts, agreements, commitments or other
understandings or arrangements to which Parent or any of its subsidiaries is a
party or by which any of them or any of their respective property or assets are
bound or affected, but excluding (A) contracts, agreements, commitments or other
understandings or arrangements entered into in the ordinary course of business
and involving, in each case, payments by Parent or any of its subsidiaries of
less than $500,000, and sales contracts entered into in the ordinary course of
business, and (B) employment agreements and stock option agreements; and (ii)
all agreements which, as of the date hereof, Parent is required to file with the
SEC pursuant to the requirements of the Exchange Act as "material contracts."

   (b) (i) neither the Parent nor any of its subsidiaries has breached, is in
default under, or has received written notice of any breach of or default under,
any of the agreements, contracts or other instruments required to be disclosed
in Section 3.5(a) of the Parent Disclosure Schedule (ii) to the best knowledge
of Parent, no other party to any of the agreements, contracts or other
instrument required to be disclosed in Section 3.5(a) of the Parent Disclosure
Schedule has breached or is in default of any of its obligations thereunder, and
(iii) to the best knowledge of Parent, each of the agreements, contracts and
other instruments required to be disclosed in Section 3.5(a) of the Parent
Disclosure Schedule is in full force and effect, except in any such case for
breaches, defaults or failures to be in full force and effect that would not
reasonably be expected to have a Parent Material Adverse Effect.

   (c) The execution and delivery of this Agreement by Parent and Merger Sub
does not, and the performance of this Agreement by Parent and Merger Sub will
not, and the consummation of the transactions contemplated hereby will not, (i)
conflict with or violate the Articles of Organization (or Certificate of
Incorporation) or By-Laws of Parent or Merger Sub, (ii) conflict with or violate
any Laws applicable to Parent or any of its subsidiaries or by which its or
their respective properties are bound or affected, or (iii) result in any breach
of or constitute a default (or an event which with notice or lapse of time or
both would become a default) under, or impair Parent's or any of its
subsidiaries' rights or alter the rights or obligations of any third party
under, or give to others any rights of termination, amendment, acceleration or
cancellation of, or result in the creation of a Parent

                                      24-
<PAGE>
 
Lien on any of the properties or assets of Parent or any of its subsidiaries
pursuant to, any note, bond, mortgage, indenture, contract, agreement, lease,
license, permit, franchise or other instrument or obligation to which Parent or
any of its subsidiaries is a party or by which Parent or any of its subsidiaries
or its or any of their respective properties are bound or affected, except in
any such case for any such conflicts, violations, breaches, defaults or other
occurrences that would not reasonably be expected to have a Parent Material
Adverse Effect.

   (d) The execution and delivery of this Agreement by Parent and Merger Sub
does not, and the performance of this Agreement by Parent and Merger Sub will
not, require any consent, approval, authorization or permit of, or filing with
or notification to, any federal, foreign, state or provincial governmental or
regulatory authority, except (i) for applicable requirements, if any, of the
Securities Act, the Exchange Act, the Blue Sky Laws, the pre-merger notification
requirements of the HSR Act, and the filing and recordation of appropriate
merger or other documents as required by the FBCA and the DGCL, and (ii) where
the failure to obtain such consents, approvals, authorizations or permits, or to
make such filings or notifications, would not reasonably be expected to have a
Parent Material Adverse Effect.

   SECTION 3.6 Compliance. Neither Parent nor any of its subsidiaries is in
conflict with, or in default or violation of, (i) any Law or Approval applicable
to Parent or any of its subsidiaries or by which its or any of their respective
properties is bound or affected or (ii) any note, bond, mortgage, indenture,
contract, agreement, lease, license, permit, franchise or other instrument or
obligation to which Parent or any of its subsidiaries is a party or by which
Parent or any of its subsidiaries or its or any of their respective properties
is bound or affected, except for any such conflicts, defaults or violations
which would not reasonably be expected to have a Parent Material Adverse Effect.

   SECTION 3.7 SEC Filings; Financial Statements.

   (a) Parent has filed all forms, reports and documents required to be filed
with the SEC since January 1, 1997 (collectively, the "PARENT SEC REPORTS"). The
Parent SEC Reports (i) were prepared in all material respects in accordance with
the requirements of the Securities Act or the Exchange Act, as the case may be,
and (ii) did not at the time they were filed (or if amended or superseded by a
filing prior to the date of this Agreement, then on the date of such filing)
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 the light of the circumstances under which they were made, not
misleading. None of Parent's subsidiaries is required to file any forms, reports
or other documents with the SEC. The redacted sections of Parent's June 1998
Settlement Agreement with VISX, Inc. (which, as redacted, is filed with the
Parent SEC Reports) contain no provisions that purport to limit, as between
Parent and the Company, the operation of any non-redacted sections addressing
the applicability of cross-licenses to third parties which acquire or are
acquired by Parent.

   (b) Each of the consolidated financial statements (including, in each case,
any related notes thereto) contained in the Parent SEC Reports has been prepared
in accordance with generally

                                      25-
<PAGE>
 
accepted accounting principles applied on a consistent basis throughout the
periods involved (except as may be indicated in the notes thereto) and each
fairly presents in all material respects the consolidated financial position of
Parent and its subsidiaries as at the respective dates thereof and the
consolidated results of its operations and cash flows and stockholders' equity
for the periods indicated, except that the unaudited interim financial
statements were or are subject to normal and recurring year-end adjustments
which were not or are not expected to be material in amount.

rights of the Parent or any of its subsidiaries, before any federal, foreign,
state or provincial court, arbitrator or administrative, governmental or
regulatory authority or body that would reasonably be expected to have a Parent
Material Adverse Effect.

   SECTION 3.11 Employee Benefit Plans; Employment Agreements.

   (a)  Section 3.11(a) of the Parent Disclosure Schedule lists as of the date
hereof all employee pension plans (as defined in Section 3(2) of ERISA), all
material employee welfare plans, (as defined in Section 3(1) of ERISA) and all
other material bonus, stock option, stock purchase, incentive, deferred
compensation, supplemental retirement, severance and other similar fringe or
employee benefit plans, programs or arrangements, written or otherwise, for the
benefit of, or relating to, any current or former employees of or consultants to
Parent, any trade or business (whether or not incorporated) which is a member of
a controlled group including Parent or which is under common control with Parent
(a "PARENT ERISA AFFILIATE") within the meaning of Section 414 of the Code, or
any subsidiary of Parent, as well as each plan with respect to which Parent or a
Parent ERISA Affiliate would incur liability under Section 4069 (if such plan
has been or were terminated) or Section 4212(c) of ERISA (all such plans,
practices, and programs are referred to herein as the "PARENT EMPLOYEE PLANS").
To the extent requested by the Company, there have been made available to the
Company copies of (i) each such written Parent Employee Plan (other than those
referred to in Section 4(b)(4) of ERISA), (ii) the most recent annual report on
form 5500 series, with accompanying schedules and attachments, filed with
respect to each Parent Employee Plan required to make such a filing, and (iii)
the most recent actuarial valuation for each Parent Employee Plan subject to
Title IV of ERISA.  For purposes of this Section 3.11 (a) the term material,
used with respect to any Parent Employee Plan, shall mean that Parent or a
Parent ERISA Affiliate has incurred or may reasonably be expected to incur
obligations in an annual amount exceeding $400,000 with respect to such Parent
Employee Plan.

   (b)   (i) None of the Parent Employee Plans promises or provides retiree
medical or other welfare benefits to any person, and none of the Parent Employee
Plans is a "multiemployer plan" as such term is defined in Section 3(37) of
ERISA; (ii) there has been no "prohibited transaction," as such term is defined
in Section 406 of ERISA and Section 4975 of the Code, with respect to any Parent
Employee Plan, which would result in any material liability of Parent or any of
its subsidiaries; (iii) all Parent Employee Plans are in compliance in all
material respects with the requirements prescribed by any and all Laws
(including ERISA and the Code), currently in effect with respect thereto
(including all applicable requirements for notification to participants or the
Department of Labor, IRS, PBGC or Secretary of the Treasury), and Parent and
each of its subsidiaries have performed all material obligations required to be
performed by them under, are not in any material respect in default under or
violation of, and have no knowledge of any default or violation by any other
party to, any of the Parent Employee Plans; (iv) each Parent Employee Plan
intended to qualify under Section 401(a) of the Code and each trust intended to
qualify under Section 501(a) of the Code is the subject of a favorable
determination letter from the IRS, and nothing has occurred which may reasonably
be expected to impair such determination; (v) all contributions required to be
made to any Parent Employee Plan pursuant to Section 412 of the Code, or the
terms of the Parent Employee Plan or any collective bargaining agreement, have
been made on or before their due dates; (vi) with respect to each Parent
Employee Plan, no "reportable event" within the meaning of Section 4043 of ERISA
(excluding any such event for which the 30 day notice requirement has been
waived under the regulations to Section 4043 of ERISA) nor any event 

                                      27-

<PAGE>
 
described in Section 4062, 4063 or 4041 of ERISA has occurred; and (vii) neither
Parent nor any Parent ERISA Affiliate has incurred, nor reasonably expects to
incur, any liability under Title IV of ERISA (other than liability for premium
payments to the PBGC arising in the ordinary course), except where the failure
of any of the foregoing to be true would not have a Parent Material Adverse
Effect.

   (c)  Section 3.11(c) of the Parent Disclosure Schedule sets forth a true and
complete list of: (i) all employment agreements with officers or employees of
Parent or any of its subsidiaries that provide for annual base salaries in
excess of $250,000; (ii) all severance agreements, programs and policies of
Parent with or relating to its employees in each case with outstanding
commitments exceeding $250,000, excluding programs and policies required to be
maintained by law; and (iii) all plans, programs, agreements and other
arrangements of Parent with or relating to its employees which contain change-
in-control provisions.

   SECTION 3.12  Labor Matters.  There are no claims or proceedings pending or,
to the knowledge of Parent or any of its subsidiaries, threatened, between
Parent or any of its subsidiaries and any of their respective employees,
asserting that the Company has committed an unfair labor practice which claims
or proceedings have or would reasonably be expected to have a Parent Material
Adverse Effect; (ii) neither Parent nor any of its subsidiaries is a party to
any collective bargaining agreement or other labor union contract applicable to
persons employed by Parent or its subsidiaries; and (iii) neither Parent nor any
of its subsidiaries has any knowledge of any strikes, slowdowns, work stoppages,
lockouts, or threats thereof, by or with respect to any employees of Parent or
any of its subsidiaries, in each case which would reasonably be expected to have
a Parent Material Adverse Effect.

   SECTION 3.13  Registration Statement; Joint Proxy Statement/Prospectus.
Subject to the accuracy of the representations of the Company in Section 2.13,
the registration statement (the "REGISTRATION STATEMENT") pursuant to which the
Parent Common Stock to be issued in the Merger will be registered with the SEC
shall not, at the time the Registration Statement (including any amendments or
supplements thereto) is declared effective by the SEC, contain any untrue
statement of a material fact or omit to state any material fact necessary in
order to make the statements included therein, in light of the circumstances
under which they were made, not misleading.  The information supplied by Parent
for inclusion or incorporation in the Joint Proxy Statement/Prospectus will not,
on the date the Joint Proxy Statement/Prospectus is first mailed to
stockholders, at the time of the Stockholders Meetings and at the Effective
Time, contain any statement which, at such time and in light of the
circumstances under which it shall be made, is false or misleading with respect
to any material fact, or will omit to state any material fact necessary in order
to make the statements therein not false or misleading; or omit to state any
material fact necessary to correct any statement in any earlier communication
with respect to the solicitation of proxies for the Stockholders Meetings which
has become false or misleading.  If at any time prior to the Effective Time any
event relating to Parent, Merger Sub or any of their respective affiliates,
officers or directors should be discovered by Parent or Merger Sub which should
be set forth in an amendment to the Registration Statement or a supplement to
the Joint Proxy Statement/Prospectus, Parent or Merger Sub will promptly inform

                                      28-

<PAGE>
 
the Company.  Notwithstanding the foregoing, Parent and Merger Sub make no
representation or warranty with respect to any information supplied by the
Company which is contained in any of the foregoing documents.  Notwithstanding
the foregoing, Parent makes no representation or warranty with respect to any
information supplied by the Company which is contained in, or furnished in
connection with the preparation of, the Registration Statement or the Joint
Proxy Statement/Prospectus.

   SECTION 3.14  Title to Property.  Neither the Parent nor any of its
subsidiaries owns any real property.

   SECTION 3.15  Taxes. Parent and its subsidiaries have filed all United States
federal income Tax Returns and all other material Tax Returns required to be
filed by them, and Parent and its subsidiaries have paid and discharged all
Taxes due in connection with or with respect to the periods or transactions
covered by such Tax Returns and have paid all other Taxes as are due, except
such as are being contested in good faith by appropriate proceedings (to the
extent that any such proceedings are required) and there are no other Taxes that
would be due if asserted by a taxing authority, except with respect to which
Parent is maintaining reserves to the extent currently required unless the
failure to do so would not reasonably be expected to have a Parent Material
Adverse Effect. Except as does not involve or would not result in liability to
Parent that would reasonably be expected to have a Parent Material Adverse
Effect: (i) there are no tax liens on any assets of Parent or any subsidiary
thereof; and (ii) neither Parent nor any of its subsidiaries has granted any
waiver of any statute of limitations with respect to, or any extension of a
period for the assessment of, any Tax. The accruals and reserves for Taxes
(including deferred taxes) reflected in the 1998 Parent Balance Sheet are in all
material respects adequate to cover all Taxes required to be accrued through the
date thereof (including interest and penalties, if any, thereon and Taxes being
contested) in accordance with generally accepted accounting principles.

   SECTION 3.16  Environmental Matters.  Except in all cases as, in the
aggregate, have not had and would not reasonably be expected to have a Parent
Material Adverse Effect, Parent and each of its subsidiaries to the best of
Parent's knowledge:  (i) have obtained all Approvals which are required to be
obtained under all applicable Environmental Laws by Parent or its subsidiaries
(or their respective agents); (ii) are in compliance with all terms and
conditions of such required Approvals, and also are in compliance with all other
limitations, restrictions, conditions, standards, prohibitions, requirements,
obligations, schedules and timetables contained in applicable Environmental
Laws; (iii) have not received notice of any past or present violations of
Environmental Laws, or any event, condition, circumstance, activity, practice,
incident, action or plan which is reasonably likely to interfere with or prevent
continued compliance with or which would give rise to any common law or
statutory liability, or otherwise form the basis of any claim, action, suit or
proceeding, against Parent or any of its subsidiaries based on or resulting from
the manufacture, processing, distribution, use, treatment, storage, disposal,
transport, or handling, or the emission, discharge or release into the
environment, of any pollutant, contaminant or hazardous or toxic material or
waste; and (iv) have taken all actions necessary under applicable Environmental
Laws to register any products or 

                                      29-
<PAGE>
 
materials required to be registered by Parent or its subsidiaries (or any of
their respective agents) thereunder.

   SECTION 3.17 Intellectual Property.

   (a)  Parent, directly or indirectly, owns, or is licensed or otherwise
possesses legally enforceable rights to use, all trademarks, trade names,
service marks, copyrights, and any applications therefor, know-how, computer
software programs or applications, and tangible or intangible proprietary
information or material that are material to the business of the Company and its
subsidiaries, taken as a whole, as currently conducted or as proposed to be
conducted (the "PARENT INTELLECTUAL PROPERTY RIGHTS"), except where the failure
to do so would not have a Parent Material Adverse Effect.

   (b)  The execution and delivery of this Agreement by Parent, and the
consummation of the transactions contemplated hereby, will neither cause Parent
or any of its subsidiaries to be in violation or default in any material respect
under any license, sublicense or agreement with respect to the Parent
Intellectual Property Rights, nor entitle any other party to any such license,
sublicense or agreement to terminate or modify such license, sublicense or
agreement, except where such violation, default, termination or modification
would not reasonably be expected to have a Parent Material Adverse Effect.  No
claims have been asserted or, to the knowledge of Parent, are threatened by any
person nor are there any valid grounds, to the knowledge of Parent, for any bona
fide claims (i) against the use by Parent or any of its subsidiaries of Parent
Intellectual Property Rights, or (ii) challenging the ownership by Parent or any
of its subsidiaries, or the validity or effectiveness of any of Parent
Intellectual Property Rights, except for such claims that would not,
individually or in the aggregate, reasonably be expected to have a Parent
Material Adverse Effect.

   (c)  Except as disclosed in the Parent SEC Reports filed prior to the date
hereof, neither the Parent nor any of its subsidiaries has interfered with,
infringed upon, misappropriated, or otherwise come into conflict with any
Intellectual Property rights of third parties, and there has never been any
charge, complaint, claim, demand, or notice alleging any such interference,
infringement, misappropriation, or violation (including any claim that Parent or
one of its Subsidiaries must license or refrain from using any Intellectual
Property rights of any third party).

   SECTION 3.18  Regulatory Matters.

   (a)  Since January 1, 1996 through the date hereof (i) there have been no
written notices, citations or decisions by any governmental or regulatory body
that any product produced, manufactured, marketed or distributed at any time by
the Company or any Company subsidiary (the "PARENT PRODUCTS") is defective or
fails to meet any applicable standards promulgated by any such governmental or
regulatory body, or any other governmental or regulatory body, agency or office
of any other jurisdiction to which the Company or any of its subsidiaries is
subject, (ii) there have been no recalls, field notifications or seizures
ordered or threatened by the FDA or any other comparable governmental or
regulatory body with respect to any of the Parent Production and (iii) none of
the

<PAGE>
 
Parent or the Parent subsidiaries have received any warning letter, Section
305 notices from the FDA or so-called Section 483 notices of adverse
observations (or comparable notices from such other governmental or regulatory
bodies).

   (b)  Except as would not, individually or in the aggregate,  have a Parent
Material Adverse Effect, with respect to each Parent Product: (i) the Parent and
its subsidiaries have obtained all applicable Licenses to permit the
manufacturing, distribution, sale (including reimbursement and pricing),
marketing, export, import or human research (including clinical and non-clinical
trials) of such Product and (ii) Parent and its subsidiaries are in full
compliance with all terms and conditions of each License in each country in
which such Parent Product is marketed, and with all requirements pertaining to
the manufacturing (including current good manufacturing practices), marketing,
export, import or human research (including good laboratory practices and
clinical and non-clinical trials) of such Parent Product which is not required
to be the subject of a License.

   (c)  There are no impediments to issuance of any Parent FDA premarket
approval application ("PMA") as to which Parent has received an approvable
letter from the FDA other than those set forth in any so-called Section 483
Notices described in the Parent Disclosure Schedule, and Parent is not aware of
any reason why it will be unable to address to the FDA's satisfaction all
observations contained in such Notices.

   SECTION 3.19  Interested Party Transactions.  Since the date of Parent's 1998
proxy statement, other than as described therein, no event has occurred that
would be required to be reported as a Certain Relationship or Related
Transaction, pursuant to Item 404 of Regulation S-K promulgated by the SEC.

   SECTION 3.20  Financial Capacity.  Parent has available sufficient funds to
satisfy its obligations to pay the Cash Consideration for all the Shares.

of its financial advisor, Hambrecht & Quist, LLC, that, as of the date hereof,
the Merger Consideration is fair to Parent from a financial point of view.

Hambrecht & Quist, LLC, the fees and expenses of which will be paid by Parent)
is entitled to any brokerage, finder's or other fee or commission in connection
with the transactions contemplated by this Agreement based upon arrangements
made by or on behalf of Parent or Merger Sub.

   SECTION 3.23  Ownership of Merger Sub; No Prior Activities.

transactions contemplated by this Agreement.

liabilities incurred in connection with its incorporation or organization and
the transactions contemplated by this Agreement and except for this Agreement
and any other agreements or arrangements contemplated by this Agreement, Merger
Sub has not and will not have incurred, directly or indirectly, through any
subsidiary or affiliate, any obligations or liabilities or engaged in any
business activities of any type or kind whatsoever or entered into any
agreements or arrangements with any person.

past practice of liabilities reflected or reserved against in the financial
statements contained in the Company SEC Reports filed prior to the date of this
Agreement or incurred in the ordinary course of business and consistent with
past practice; or

   (j)   take, or agree in writing or otherwise to take, any of the actions
described in Sections 4.1 (a) through (i) above.

   SECTION 4.2  No Solicitation.

   (a)  The Company shall not, directly or indirectly, through any officer,
director, employee, representative or agent of the Company or any of its
subsidiaries, (i) solicit, initiate or encourage the initiation of any inquiries
or proposals regarding any merger, sale of substantial assets, sale of shares of
capital stock (including without limitation by way of a tender offer) or similar
transactions involving the Company or any subsidiaries of the Company other than
the Merger (any of the foregoing inquiries or proposals being referred to herein
as an "ACQUISITION PROPOSAL"), (ii) engage in negotiations or discussions
concerning, or provide any nonpublic information to any person relating to, any
Acquisition Proposal or (iii) agree to, approve or recommend any Acquisition
Proposal.  Nothing contained in this Section 4.2(a) shall prevent the Board of
Directors of the Company from considering, negotiating, approving and
recommending to the stockholders of the Company a bona fide Acquisition Proposal
not solicited in violation of this Agreement, provided the Board of Directors of
the Company concludes in good faith that the Acquisition Proposal would
constitute a Superior Proposal (as defined below) and determines in good faith
(upon advice of outside counsel) that it is required to do so in order to
discharge properly its fiduciary duties.

   (b)   The Company shall immediately notify Parent after receipt of any
Acquisition Proposal, or any modification of or amendment to any Acquisition
Proposal, or any request for nonpublic information relating to the Company or
any of its subsidiaries in connection with an Acquisition Proposal or for access
to the properties, books or records of the Company or any subsidiary by any
person or entity that informs the Board of Directors of the Company or such
subsidiary that it is considering making, or has made, an Acquisition Proposal.
Such notice to Parent shall be made orally and in writing, and shall identify
the person or entity making the Acquisition Proposal and set forth the material
terms and condition  of the Acquisition Payment.  The notice shall also indicate
whether the Company is providing or intends to provide the person making the
Acquisition Proposal with access to information concerning the Company as
provided in Section 4.2(c).

                                      34-

<PAGE>
 
   (c)  If the Board of Directors of the Company receives a request for material
nonpublic information by a person who makes, or indicates that it is considering
making, a bona fide Acquisition Proposal, and the Board of Directors determines
in good faith and upon the advice of independent counsel that it is required to
cause the Company to act as provided in this Section 4.2(c) in order to
discharge properly the directors' fiduciary duties, then, provided the person
making the Acquisition Proposal has executed a confidentiality agreement
substantially similar to the one then in effect between the Company and Parent,
the Company may provide such person with access to information regarding the
Company.

   (d)  The Company shall ensure that the officers and directors of the Company
and its subsidiaries and any investment banker or other advisor or
representative retained by the Company are aware of the restrictions described
in this Section 4.2.

   (e)   For purposes of this Agreement, "Superior Proposal" means a bona fide
Acquisition Proposal that the Board of Directors of the Company determines in
its good faith judgment to be more favorable to the Company's stockholders than
the Merger (based on the written opinion, with only customary qualifications, of
the Company's independent financial advisor that the value of the consideration
of the Company's stockholders provided for in such proposal exceeds the value of
the consideration to the Company's stockholders provided for in the Merger) and
for which financing, to the extent required, is then committed or which, in the
good faith judgment of the Board of Directors of the Company (based on the
written advice of the Company's independent financial advisor), is reasonably
capable of being obtained by the person making the proposal.

party may reasonably request, and each shall make available to the other the

Parent and the Company.

   SECTION 5.5  Consents; Approvals.  The Company and Parent shall each use all

rulings and approvals), and the Company and Parent shall make all filings
(including, without limitation, all filings with United States and foreign
governmental or regulatory agencies) required in connection with the
authorization, execution and delivery of this Agreement by the Company and
Parent and the consummation by them of the transactions contemplated hereby, in

identifying all persons who are, and at the time of the Company Stockholders
Meeting are expected to be, "affiliates" of the Company, for purposes of Rule
145 under the Securities Act ("RULE 145"). The Company shall use its best
efforts to cause each person who is identified as an "affiliate" in the
Affiliate Letter to deliver, prior to the Effective Time, a written agreement
(an "AFFILIATE AGREEMENT") in substantially the form of Exhibit 5.6(a).

   SECTION 5.7  Indemnification and Insurance.

   (a)  The Certificate of Incorporation and By-Laws of the Surviving
Corporation shall contain the provisions with respect to indemnification set
forth in the Articles of Incorporation and 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 adversely affect the
rights thereunder of individuals who at or before the Effective Time were
directors, officers, employees or agents of the Company, unless such
modification is required by law.

   (b)   The Company shall, to the fullest extent permitted under applicable law
or under the Company's Articles of Incorporation or By-Laws and regardless of
whether the Merger becomes effective, indemnify and hold harmless and, after the
Effective Time, Parent and the Surviving Corporation shall, to the fullest
extent permitted under applicable law or under the Surviving Corporation's
Certificate of Incorporation or By-Laws, indemnify and hold harmless, each
present and former director, officer or employee of the Company or any of its
subsidiaries (collectively, the "INDEMNIFIED PARTIES") against any costs or
expenses (including attorneys' fees), judgments, fines, losses, claims, damages,
liabilities and amounts paid in settlement in connection with any claim, action,
suit, proceeding or investigation, whether civil, criminal, administrative or
investigative, (x) arising out of or pertaining to the transactions contemplated
by this Agreement or (y) otherwise with respect to any acts or omissions
occurring at or prior to the Effective Time, to the same extent as provided in
the Company's Articles of Incorporation or By-Laws or any applicable contract or
agreement as in effect on the date hereof, in each case for a period of six
years after the date hereof.  In the event of any such claim, action, suit,
proceeding or investigation (whether arising before or after the Effective
Time), (i) any counsel retained by 

                                      37-


<PAGE>
 
the Indemnified Parties for any period after the Effective Time shall be
reasonably satisfactory to the Surviving Corporation, (ii) after the Effective
Time, Parent or the Surviving Corporation shall pay the reasonable fees and
expenses of such counsel, promptly after statements therefor are received, and
(iii) Parent and the Surviving Corporation will cooperate in the defense of any
such matter; provided, however, that neither Parent nor the Surviving
Corporation shall be liable for any settlement effected without its written
consent (which consent shall not be unreasonably withheld); and provided,
further, that, in the event that any claim or claims for indemnification are
asserted or made within such six-year period, all rights to indemnification in
respect of any such claim or claims shall continue until the disposition of any
and all such claims. The Indemnified Parties as a group may retain only one law
firm to represent them with respect to any single action unless there is, under
applicable standards of professional conduct, a conflict on any significant
issue between the positions of any two or more Indemnified Parties.

   (c)   Parent and the Surviving Corporation shall honor and fulfill in all
respects the obligations of the Company pursuant to indemnification agreements
with the Company's directors and officers existing at or before the Effective
Time.

   (d)   For a period of three years after the Effective Time, Parent shall
maintain or cause the Surviving Corporation to maintain in effect, if available,
directors' and officers' liability insurance covering those persons who are
currently covered by the Company's directors' and officers' liability insurance
policy (a copy of which has been made available to Parent) on terms comparable
to those now applicable to directors and officers of the Company; provided,
however, that in no event shall Parent or the Surviving Corporation be required
to expend in excess of 150% of the annual premium currently paid by the Company
for such coverage; and provided further, that if the premium for such coverage
exceeds such amount, Parent or the Surviving Corporation shall purchase a policy
with the greatest coverage available for such 150% of the annual premium.

   (e)   This Section 5.7 shall survive the consummation of the Merger at the
Effective Time, is intended to benefit the Company, the Surviving Corporation
and the Indemnified Parties, shall be binding on all successors and assigns of
Parent and the Surviving Corporation and shall be enforceable by the Indemnified
Parties, their heirs and their representatives.

   SECTION 5.8  Notification of Certain Matters.  The Company shall give prompt
notice to Parent, and Parent shall give prompt notice to the Company, of (i) the
occurrence or nonoccurrence of any event known to such party the occurrence or
nonoccurrence of which would be likely to cause any representation or warranty
contained in this Agreement to become materially untrue or inaccurate, or (ii)
any failure of the Company, Parent or Merger Sub, as the case may be, materially
to comply with or satisfy any covenant, condition or agreement to be complied
with or satisfied by it hereunder; provided, however, that the delivery of any
notice pursuant to this Section shall not limit or otherwise affect the remedies
available hereunder to the party receiving such notice; and provided further
that failure to give such notice shall not be 

                                      38-

<PAGE>
 
treated as a breach of covenant for the purposes of Sections 6.2(a) or 6.3(a)
unless the failure to give such notice results in material prejudice to the
other party.

   SECTION 5.9  Further Action/Tax Treatment.  Upon the terms and subject to the
conditions hereof each of the parties hereto shall use all reasonable efforts to
take, or cause to be taken, all actions and to do, or cause to be done, all
other things necessary, proper or advisable to consummate and make effective as
promptly as practicable the transactions contemplated by this Agreement, to
obtain in a timely manner all necessary waivers, consents and approvals and to
effect all necessary registrations and filings, and otherwise to satisfy or
cause to be satisfied all conditions precedent to its obligations under this
Agreement.  The foregoing covenant shall not include any obligation by Parent to
agree to divest, abandon, license or take similar action with respect to any
assets (tangible or intangible) of Parent or the Company.  Each of Parent,
Merger Sub and the Company shall use its reasonable best efforts (which shall
not include increasing the Merger Consideration or the Stock Consideration or
the Per Share Stock Consideration) to cause the Merger to qualify, and will not
(both before and after consummation of the Merger) take any actions which to its
knowledge would reasonably be expected to prevent the Merger from qualifying as
a reorganization under the provisions of Section 368 of the Code.  Following the
Merger, Parent will cause the Surviving Corporation to continue the Company's
historic business or use a significant portion of the Company's historic
business assets in a business.

   SECTION 5.10  Public Announcements. Parent and the Company shall consult with
each other before issuing any press release with respect to the Merger or this
Agreement and shall not issue any such press release or make any such public
statement without the prior consent of the other party, which shall not be
unreasonably withheld; provided, however, that a party may, without the prior
consent of the other party, issue such press release or make such public
statement as may upon the advice of counsel be required by law or the rules and
regulations of the Nasdaq National Market System, if it has used all reasonable
efforts to consult with the other party prior thereto.

   SECTION 5.11  Accountants' Letters.  Upon reasonable notice from the other,
Parent and the Company shall use their respective best efforts to cause Deloitte
& Touche LLP and Arthur Andersen LLP, respectively, to deliver to Parent or the
Company, as the case may be, a letter, dated within 2 business days of the
Effective Date of the S-4 Registration Statement covering such matters as are
requested by Parent or the Company and as are customarily addressed in
accountant's "comfort" letters.

   SECTION 5.12  Board Representation.  As of the Effective Time or as soon as
practicable thereafter, the Board of Directors of Parent will take such action
as is necessary to cause Glenn Bradley to be elected to serve as a director of
Parent for the vacant term expiring at Parent's annual meeting in 2000 (the
"Outside Director"), and  Randy W. Frey to be elected as a director of Parent
for the vacant term expiring at Parent's annual meeting in 2001.  The Board of
Directors of Parent will nominate the Outside Director for re-election at
Parent's annual meeting in 2000, provided that such Outside Director (x) is
"independent" as such term is applied under

subject to the reasonable approval of Parent, shall be entitled to attend
meetings of the Board of Directors until the third anniversary of the Effective
Time, subject to the Board's right to have portions of any such meeting open
only to members of the Board. If the observer named in the Joint Proxy
Statement/Prospectus is unable to continue as an observer until the end of the
term, Parent agrees that the directors named by the Company may designate a
replacement. Parent agrees to pay the observer's reasonable travel expenses in
connection with the observer's attendance at Board meetings.

reasonable best efforts to continue the quotation of the Company Common Stock
and Parent Common Stock, respectively, on The Nasdaq National Market during the
term of this Agreement.

efforts to cause the Parent Shares to be issued in the Merger to be approved for
quotation, upon official notice of issuance, on The Nasdaq National Market.

   SECTION 5.15  Joint Shareholder Communications Efforts.  The Company and
Parent agree to use their reasonable best efforts to conduct a joint
communications program, including presentations and meetings, with institutional
stockholders of both the Company and Parent, for the purpose of communicating
the synergy, strategy and prospects for the combined companies after the Merger.
Such presentations and meetings shall take place in those cities of the United
States where such institutional stockholders are located and shall be conducted
for 7 to 10 business days during the three-week period preceding the Stockholder
Meetings.

   SECTION 5.16  Dismissal of Civil Actions.  As soon as practicable after the
date hereof, the Company shall stipulate to the dismissal, without prejudice, of
all claims it has alleged against Parent and Pillar Point Partners in Autonomous
                                                                      ----------

                AUTONOMOUS TO BE ACQUIRED BY SUMMIT TECHNOLOGY

ORLANDO, FL (OCTOBER 1, 1998) AUTONOMOUS TECHNOLOGIES CORPORATION (NASDAQ NM:
ATCI) announced today that is has agreed to merge with a subsidiary of Waltham,
MA based Summit Technology, Inc. (NASDAQ NM: BEAM) subject to the approval of
the shareholders of both companies.  Shareholders of Autonomous will receive
part cash and part stock in Summit in exchange for their shares in Autonomous
under a formula based on the average closing price of Summit for the ten day
period prior to closing.

The total merger consideration is 11,650,400 shares of Summit stock at the time
of closing and an equal amount of value in cash, up to a maximum of $50 million
in cash.  Assuming the holders of the Autonomous outstanding shares of preferred
stock elect to have their shares redeemed for cash, and assuming that the Summit
stock is valued at $4.00 per share (the average closing price for the ten
trading days to and including September 30), and making certain assumptions
about stock options and warrants, each share of Autonomous common stock will be
exchanged for approximately .94 shares of Summit stock and approximately $2.50
in cash. The amount of consideration is subject to certain adjustments based on
the number of shares outstanding, including equivalent shares relating to
options and warrants and any cash advances by Summit to Autonomous. The actual
amounts will be based on the average closing price at closing.

Summit has a royalty-free cross license on patents held by VISX as a result of a
settlement agreement between Summit and VISX dissolving Pillar Point Partners.
We believe that, as part of Summit, the Autonomous LADARVision System will be
marketed on a per procedure fee basis with no royalties to be paid to any third
parties.

Meetings of the Summit and Autonomous shareholders are planned to take place as
soon as possible, but probably in December or January, to take the actions
necessary to effectuate the merger.  A joint proxy statement will be sent to
Autonomous and Summit shareholders approximately 30 days before the date of the
meetings.

Randy Frey, Chairman and CEO of Autonomous commented, "This is a powerful
combination with a clear objective of gaining market share in LVC procedures
within this high growth industry.  Summit's financial strength, equipment
business infrastructure and VISX license are highly aligned with our desire to
reduce commercialization risk to Autonomous shareholders.  The Autonomous
LADARVision product, technology leadership position and strong development team,
coupled with the strengths of Summit, will allow the combined company to set
very high goals for market share. I look forward to joining the talented
management team at Summit."

"This combination reflects our commitment to be the leading provider of products
and services to the refractive surgeon and strengthens our competitive position
as we seek to regain leadership in the fast-growing business of laser vision
correction", stated Robert Palmisano, chief executive officer of Summit.

Autonomous is engaged in the design and development of next-generation excimer
laser instruments for laser refractive surgery.  The Company's LADARVision
System combines laser radar eye tracking with narrow beam shaping technology.

Summit Technology is a leading developer, manufacturer and marketer of
ophthalmic laser systems designed to correct common vision disorders such as
nearsightedness, farsightedness and astigmatism.  In 1995, Summit was the first
excimer laser company to receive FDA approval for its Apex excimer laser system
for the correction of mild to moderate myopia in the U.S.  In addition, through
its wholly owned subsidiary, Lens Express, Summit sells contact lenses and
related products.


This press release contains forward-looking statements within the meaning of
section 27A of the Securities Act of 1933 and Section 21E of the Securities
Exchange Act of 1934. Statements containing terms such as "believes," "does not
believe," "no reason to believe," "expects," "plans," "intends," "estimates," or
"anticipates" are considered to contain uncertainty and are forward-looking
statements.  Actual results could differ materially from those projected in the
forward-looking statements as a result of a number of important factors,
including: a decline in the price of Summit stock prior to the closing; that
there are no assurances the shareholders of both companies will take the
necessary actions to effectuate the transaction; and that competitive responses
may occur preventing the achievement of increased market share.  For a
discussion of the other important factors that could affect the Company's
results, please refer to the Overview section, the Management's Discussion and
Analysis of Financial Condition and Results of Operations, and the Risk Factors
section in the Company's Annual Report on Form 10-K as amended.
