         AMENDMENT NO. 1, dated as of May 15, 1996 (this "Amendment"), to the
Agreement and Plan of Merger, dated as of April 19, 1996, among (i) Summit
Technology, Inc., a Massachusetts corporation (the "Buyer"), (ii) Summit
Acquisition Corporation, a Florida corporation and wholly owned subsidiary of
the Buyer ("Summit Sub"), (iii) Mordechai Golan, Creslin Limited, Menderes

"Company").

                              W I T N E S S E T H

         WHEREAS, the Buyer, Summit Sub, the Shareholders and the Company have
entered into an Agreement and Plan of Merger, dated as of April 19, 1996 (the
"Merger Agreement"; capitalized terms not defined herein have the meanings
ascribed to them in the Merger Agreement); and

         WHEREAS, the Buyer, Summit Sub, the Shareholders and the Company desire
to amend the Merger Agreement.

         NOW, THEREFORE, in consideration of the premises and of the mutual
agreements and understandings hereinafter set forth, the parties hereto agree as
follows:

         SECTION 1. Amendment to the Merger Agreement.  The Merger Agreement is,
as of the date hereof, hereby amended as follows:

         (a)      Section 3.4 shall be restated in full to read as follows:

                  "3.5. Conversion of Common Stock. At the Effective Time, all
         of the issued and outstanding shares (the "Shares") of Common Stock
         shall, by virtue of the Merger and without any action on the part of
         the holders thereof, be converted into the immediate right to receive a
         total number of shares of Buyer's Common Stock, $.01 par value ("Buyer
         Common Stock") that is equal to the quotient obtained by dividing
         $39,700,000 by the average closing price of Buyer Common Stock on the
         Nasdaq National Market System (as reported in the Eastern Edition of
         The Wall Street Journal) during the twenty trading day period ending on
         May 10, 1996 (the "Average Price"); provided, however, that in no event
         will such number be greater than 1,708,500 shares or less than
         1,428,571 shares of Buyer Common Stock, except as necessary to make
         appropriate adjustments for stock splits, dividends, recapitalizations
         and the like. The certificates evidencing the shares of Buyer Common
         Stock shall bear the legend required under Section 14 of this
         Agreement."
<PAGE>   2
         (b)      The following definition shall be added as Section 11.2.23:

                           "11.2.23.  HSR Act.  The term "HSR Act" shall mean
                           the Hart-Scott - Rodino Antitrust Improvements Act of
                           1976."

         SECTION 2. Effect of Amendment.  Except as and to the extent modified
by this Amendment, the Merger Agreement shall remain in full force and effect in
all respects.

         SECTION 3. Governing Law. This Amendment shall be governed by, and
construed in accordance with, the domestic substantive laws of the Commonwealth
of Massachusetts, without giving effect to any choice or conflict of law
provision or rule that would cause the application of the domestic substantive
laws of any other jurisdiction.

         SECTION 4. Counterparts. This Amendment may be executed in one or more
counterparts, and by the different parties hereto in separate counterparts, each
of which when executed shall be deemed to be an original but all of which taken
together shall constitute one and the same agreement.

                                      -2-

                          AGREEMENT AND PLAN OF MERGER

         This AGREEMENT AND PLAN OF MERGER (the "Agreement") is made as of the
19th day of April 1996, by and among (i) Summit Technology, Inc., a
Massachusetts corporation (the "Buyer"), (ii) Summit Acquisition Corporation, a
Florida corporation ("Summit Sub"), (iii) Mordechai Golan, Creslin Limited,
Menderes Akdag and Huseyin Kizanlikli (each a "Shareholder" and collectively,
the "Shareholders") and (iv) Lens Express, Inc., a Florida corporation (the
"Company").

         WHEREAS, it is deemed advisable and in the best interests of each of
the Buyer, Summit Sub, the Company and the Shareholders that Summit Sub be
merged with and into the Company pursuant to the laws of the State of Florida
upon the terms and conditions contained in this Agreement.

         NOW, THEREFORE, in consideration of the foregoing and the mutual
agreements and covenants set forth below, the parties hereto agree as follows:

1.       DEFINITIONS.

         Certain terms are used in this Agreement as specifically defined
herein. These definitions are set forth or referred to in Section 11.

2.       ACQUISITION OF CALL MART

         The Company agrees that on or prior to the consummation of the Merger
it will acquire all of the outstanding capital stock of Call Mart, Inc., a
Florida corporation ("Call Mart") solely in exchange for common stock, par value
$1.00 per share (the "Common Stock") of the Company. Unless the context
otherwise requires, the representations, warranties and covenants of the Company
and the Shareholders in this Agreement assume that the Company acquired Call
Mart on or before the date hereof. In addition, Menderes Akdag and Huseyin
Kizanlikli are executing this Agreement each in his individual capacity as a
stockholder of Call Mart and for all purposes of this Agreement each shall be
deemed a Shareholder. References in this Agreement to the "Company" shall,
unless the context otherwise requires, be deemed to include the Company and Call
Mart.

3.       THE MERGER.

         3.1. Constituent, Surviving Corporation. The Company and Summit Sub
shall be the constituent corporations to the Merger. At the Effective Time,
Summit Sub shall be merged with and into the Company in accordance with the
Business Corporation Act of the State of Florida (the "Corporation Law"), and
the Company shall be the surviving corporation of the Merger (herein sometimes
called the "Surviving Corporation"). The name, identity,
<PAGE>   10
existence, rights, privileges, powers, franchises, properties and assets of the
Company shall continue unaffected and unimpaired by the Merger. At the Effective
Time, the identity and separate existence of Summit Sub shall cease, and all of
the rights, privileges, powers, franchises, properties and assets of Summit Sub
shall be vested in the Surviving Corporation.

         3.2. Time and Place of Closing. Subject to Section 13, the closing of
the Merger and the other transactions contemplated by this Agreement (the
"Closing") shall take place at the offices of Ropes & Gray, Boston,
Massachusetts, or such other location as the parties may agree, at 9:00 a.m.
(Boston time) on the third business day after the date of the expiration of the
applicable waiting period under the HSR Act, or, if the conditions to Closing
set forth in Section 8 shall not have been satisfied at such date, at such later
time or date as specified by Buyer, or in the event that the conditions set
forth in Section 9 shall not have been satisfied at such date, at such later
time or date as specified by the Shareholders, in each case prior to termination
of this Agreement, by not fewer than three (3) business days' prior written
notice to the other party (such date being referred to herein as the "Closing
Date").

         3.3. Charter; By-Laws. From and after the Effective Time and thereafter
until amended as provided by law, the Articles of Incorporation of the Surviving
Corporation shall be the Charter of the Company and the By-Laws of the Surviving
Corporation shall be the ByLaws of the Company, each as in effect immediately
prior to the Effective Time.

         3.4. Conversion of Common Stock. At the Effective Time, all of the
issued and outstanding shares (the "Shares") of Common Stock shall, by virtue of
the Merger and without any action on the part of the holders thereof, be
converted into the immediate right to receive a total number of shares of
Buyer's Common Stock, $.01 par value ("Buyer Common Stock") that is equal to the
quotient obtained by dividing $39,700,000 by the average closing price of Buyer
Common Stock on the Nasdaq National Market System (as reported in the Eastern
Edition of The Wall Street Journal) during the twenty trading day period ending
on the trading date immediately preceding the date of the expiration of the
applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act
of 1976 (the "HSR Act") (the "Average Price"); provided, however, that in no
event will such number be greater than 1,700,000 shares or less than 1,428,571
shares of Buyer Common Stock, except as necessary to make appropriate
adjustments for stock splits, dividends, recapitalizations and the like. The
certificates evidencing the shares of Buyer Common Stock shall bear the legend
required under Section 14 of this Agreement.

         3.5. Escrow. Ten percent (10%) of the aggregate number of shares of
Buyer Common Stock that each Shareholder shall become entitled to receive
pursuant to Section 3.4 (which in no event shall exceed a value based on the
Average Price of $4,000,000) shall be deposited into an escrow with Fleet
National Bank, as Escrow Agent (the "Escrow Agent"). Certificates representing
shares so deposited shall be registered in the name of the Shareholder entitled
to receive such shares. The rights and obligations of the Shareholders, the
Buyer and the Escrow Agent shall be in accordance with the escrow agreements in
the forms attached as


                                       -2-
<PAGE>   11
Exhibit 3.5 hereto (individually, the "General Escrow Agreement" and the
"Litigation Escrow Agreement", collectively, "the Escrow Agreements").

         3.6. No Fractional Shares. No certificates or scrip evidencing
fractional shares of Buyer Common Stock shall be issued upon the surrender for
exchange of certificates evidencing shares of Common Stock, and no dividend,
stock split or other distribution shall relate to any fractional share of Buyer
Common Stock, and such fractional interests shall not entitle the owner thereof
to vote or to any rights as a holder of Buyer Common Stock. In lieu of any
fractional shares of Buyer Common Stock, the Shareholders will receive payment
in cash for such shares.

         3.7. Conversion of Summit Sub Common Stock. At the Effective Time, each
share of common stock, par value $.01, of Summit Sub ("Summit Sub Common Stock")
outstanding immediately prior to the Effective Time shall, by virtue of the
Merger and without any action on the part of the holder thereof, be converted
into one validly issued, fully paid, and nonassessable share of common stock of
the Surviving Corporation, $1.00 par value.

         3.8. Filing of Certificate of Merger. At the Closing, the Company and
Summit Sub will cause a certificate of merger to be executed, attested and filed
with the office of the Secretary of State of the State of Florida as provided in
the Corporation Law.

         3.9. Effect of the Merger. The Merger shall have the effect set forth
in the Corporation Law.

4.       GENERAL REPRESENTATIONS AND WARRANTIES OF THE COMPANY AND
         THE SHAREHOLDERS.

         In order to induce the Buyer to enter into and perform this Agreement
and to consummate the transactions contemplated hereby, the Company and the
Shareholders hereby jointly and severally make the following representations and
warranties to the Buyer.

         4.1.     Corporate Matters, etc.

                  4.1.1. Organization, Power and Standing. (a) The Company is a
         corporation duly organized, validly existing and in good standing under
         the laws of the jurisdiction of its incorporation and has all requisite
         corporate power and authority to execute, deliver and perform this
         Agreement, and to consummate the transactions contemplated hereby. The
         Company is duly qualified to do business as a foreign corporation, and
         is in good standing as such, in each jurisdiction in which the failure
         to be so qualified and in good standing could reasonably be expected to
         have a Material Adverse Effect on the Company.


                                       -3-
<PAGE>   12
                  (b) The Company has full right, capacity, corporate power and
         authority to enter into this Agreement and to perform and carry out its
         obligations hereunder. The execution and delivery of this Agreement and
         the consummation of the transactions contemplated hereby have been duly
         and validly authorized by the Company's Board of Directors and
         shareholders. No other corporate acts or proceedings on the part of the
         Company are necessary to authorize this Agreement or the transactions
         contemplated hereby. This Agreement constitutes the valid and legally
         binding obligation of the Company and each of the Shareholders in
         accordance with its terms, except as limited by applicable bankruptcy,
         insolvency, reorganization, moratorium or other laws of general
         application of equitable principles when equitable remedies are sought
         (assuming such obligations are also binding on Buyer). The Company
         shall furnish to Buyer at Closing certified copies of all corporate
         resolutions authorizing the transactions herein.

                  4.1.2. Capitalization; Title to Shares. The only issued and
         outstanding shares of capital stock of the Company are the Shares, all
         of which have been duly authorized and validly issued and are fully
         paid and non-assessable, and all of which are beneficially owned and
         held of record by the Shareholders. There is no Contractual Obligation
         or Charter or By-law provision which obligates the Company to issue,
         purchase or redeem, or make any payment in respect of, any shares of
         capital stock or other securities convertible into or exchangeable for
         shares of capital stock or which provides for any stock appreciation or
         similar right or grants any right to share in the equity, income,
         revenues or cash flow of the Company. The transfer and delivery of the
         Shares by the Shareholders to Buyer as contemplated by this Agreement
         will transfer good title to the Shares to Buyer, free and clear of all
         security interests, liens, claims, encumbrances and other contractual
         restrictions of any kind, in each case except for any of the foregoing
         created or permitted to exist by or on behalf of Buyer.

                  4.1.3. Subsidiaries. The Company has no Subsidiaries except
         Call Mart.

                  4.1.4. Charter and By-laws. The Shareholders have heretofore
         caused to be delivered to the Buyer a true and complete copy of the
         Company's Charter and By- laws.

         4.2.     Financial Statements.

         (a) Exhibit 4.2 hereto contains the true and complete copies of the

by such statements and present fairly in all material respects the financial
position, the results of operations and the changes in financial position, as

indicated, and for the respective entities or divisions indicated, except that
such unaudited Financial Statements were or are subject to normal and recurring
year-end and tax adjustments.

         (b) Exhibit 4.2 hereto also contains true and complete copies of the

States in compliance with all applicable rules and regulation of the United
States Food & Drug Administration (the "FDA").

         (c) Equipment. Exhibit 4.4(c) to this Agreement contains a complete and
accurate schedule describing, and specifying the location of, all major
equipment in the possession of, or used by, the Company on the date hereof.

         (d) Proprietary Rights. To the Shareholders' and the Company's
knowledge, there are no patents, patent applications, trademarks, service marks,
trade names, corporate names or copyrights necessary to the conduct of the
business of the Company as now conducted other than the items listed in Exhibit

third party infringes upon the rights of the Company to the items listed in
Exhibit 4.4(d), except as noted thereon. To the Shareholders' and the Company's
knowledge, the Company has good title to all of the trademarks and trade names

         (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 Buyer's or any of its subsidiaries' rights or alter
         the rights or obligations of any third party under, or give to others

         Buyer or any of its subsidiaries is a party or by which Buyer 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 could not
         reasonably be expected to have a Material Adverse Effect on the Buyer.

                  6.6.2. Consents. The execution and delivery of this Agreement
         by Buyer does not, and the performance of this Agreement by Buyer will
         not, require any consent, approval, authorization or permit of, or
         filing with or notification to, any governmental or regulatory
         authority, domestic or foreign, except (i) for applicable requirements,
         if any, of the Securities Act of 1933, as amended, and the rules and
         regulations thereunder (the "1933 Act"), the Securities Exchange Act of
         1934, as amended, and the rules and regulations thereunder (the "1934
         Act"), state securities laws or blue sky laws and the rules and
         regulations thereunder, the HSR Act and (ii) where the failure to
         obtain such consents, approvals, authorizations or permits, or to make
         such filings or notifications, would not prevent or delay consummation
         of the transactions contemplated hereby, or otherwise prevent Buyer
         from performing its obligations under this Agreement, and would not
         have a Material Adverse Effect on the Buyer.

         6.7. SEC Filings; Financial Statements. Buyer has timely filed all
forms, reports and documents required to be filed with the SEC since January 1,
1990 (collectively, the "Buyer SEC Reports"), and has heretofore delivered to
the Shareholders, in the form filed with the SEC, (i) its Annual Reports on Form
10-K for the fiscal years ended December 31, 1993, 1994, and 1995 (ii) all proxy
statements relating to Buyer's meetings of stockholders (whether annual or
special) held since January 1, 1995, (iii) all other reports or registration
statements (other than Reports on Form 10-Q not referred to in clause (ii)
above) filed by Buyer with the SEC since January 1, 1995, and (iv) all
amendments and supplements to all


                                      -17-
<PAGE>   26
such reports and registration statements filed by Buyer with the SEC. The Buyer
SEC Reports and any such reports, forms and other documents filed by Buyer after
the date of this Agreement (i) were prepared or will be prepared in all material
respects in accordance with, and comply (or will comply) with, the requirements
of the 1933 Act or the 1934 Act, as the case may be, and (ii) did not at the
time they were filed or will not at the time they are 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 Buyer's subsidiaries is required to file any
forms, reports or other documents with the SEC. Each of the consolidated
financial statements (including, in each case, any related notes thereto)
contained in the Buyer SEC Reports has been prepared in accordance with
generally 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 the consolidated financial position of Buyer
and its subsidiaries as at the respective dates thereof and the consolidated
results of its operations and cash flows 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.

         6.8. Absence of Certain Changes or Events. Since December 31, 1995,
Buyer has conducted its business in the ordinary course and there has not
occurred: (i) any Material Adverse Effect on the Buyer; (ii) any amendments or
changes in the Charter or By-Laws of Buyer; (iii) any damage to, destruction or
loss of any assets of the Buyer (whether or not covered by insurance) that could
have a Material Adverse Effect on the Buyer; (iv) any material change by Buyer
in its accounting methods; (v) any material revaluation by Buyer of any of its
assets, including without limitation, writing down the value of inventory or
writing off notes or accounts receivable other than in the ordinary course of
business; or (vi) any sale of a material amount of assets of Buyer except in the
ordinary course of business.

         6.9. Regulatory Environment. The Buyer understands that various
government regulatory agencies may argue or have argued that the Company may be
subject to laws, rules or regulations ("Regulatory Provisions"), the
applicability of which the Company may dispute or has disputed in good faith.
The Buyer further understands that such Regulatory Provisions have resulted, and
may continue to result, in related expenses to the Company.

         agreement made by or on behalf of the Shareholders or the Company in
         this Agreement. Notwithstanding anything herein to the contrary, the
         obligation of each Shareholder to indemnify an Indemnitee for breaches
         of such Shareholder's representations and warranties in Section 5 shall
         be several and not joint.

                  10.1.2. Seriani and Other Litigation. Without limiting the
         generality of the Shareholders' obligations under Section 10.1.1., the
         Shareholders agree to indemnify the Company and the Buyer against any
         Losses arising out of Joseph Seriani and Rhonda Seriani v. Yalie Golan,
         Engin Kamil Yesil, Mordechai Golan and Lens Express, Inc. (Cir. Ct.,
         Broward Cty, No. 93-08026) or any subsequent litigation filed that
         alleges similar conduct occurring prior to the date hereof (the
         "Seriani Litigation") and any Losses arising out of three complaints
         filed in late February and early March 1996 with the Equal Employment
         Opportunity Commission; provided, however, that the Buyer agrees to pay
         up to $75,000 in post Closing legal fees incurred by the Company in
         connection with the Seriani Litigation.

                  10.1.3. The Buyer. In the case of the Buyer as Indemnifying
         Party (i) any breach of a representation or warranty made by or on
         behalf of the Buyer in this Agreement or any document, instrument or
         certificate delivered pursuant thereto (as each such representation or
         warranty would read if all qualifications as to knowledge or
         materiality (including without limitation in the definition of Material
         Adverse Effect) were deleted therefrom); (ii) any breach or violation
         of any covenant or agreement made by or on behalf of the Buyer in this
         Agreement and (iii) the operation of the Company after Closing.

         10.2. Third Party Claims. Promptly after the receipt by any Indemnitee
of notice of the commencement of any Action against such Indemnitee by a third
party, such Indemnitee shall, if a claim with respect thereto is or may be made
against any Indemnifying Party pursuant to this Section 10, give such
Indemnifying Party written notice thereof. Subject to the Cut-Off Date, the
failure to give such notice shall not relieve any Indemnifying Party from any
obligation hereunder except where, and then solely to the extent that, such
failure actually and materially prejudices the rights of such Indemnifying
Party. Such Indemnifying Party shall have the right to defend such claim, at
such Indemnifying Party's expense and with counsel of its choice reasonably
satisfactory to the Indemnitee, provided that the Indemnifying


                                      -26-
<PAGE>   35
Party conducts the defense of such claim actively and diligently. If the
Indemnifying Party assumes the defense of such claim, the Indemnitee agrees to
reasonably cooperate in such defense so long as the Indemnitee is not materially
prejudiced thereby. So long as the Indemnifying Party is conducting the defense
of such claim as provided in the previous sentence, the Indemnitee may retain
separate co-counsel at its sole cost and expense and may participate in defense
of such claim, and neither the Indemnified Party nor the Indemnitee will consent
to the entry of any judgment or enter into any settlement with respect to such
claim without the prior written consent of the other, which consent will not be
unreasonably withheld. In the event the Indemnifying Party does not or ceases to
conduct the defense of such claim as so provided, (x) the Indemnitee may defend
against, and consent to the entry of any judgment or enter into any settlement
with respect to, such claim in any manner it may reasonably deem to be
appropriate, (y) the Indemnifying Party will reimburse the indemnitee promptly
and periodically for the reasonable and actual costs of defending against such
claim, including attorneys' fees and expenses, and (z) the Indemnifying Party
will remain responsible for any Losses the Indemnitee may suffer as a result of
such claim to the full extent provided in this Section 10.

         10.3. Limitations on Indemnification.

         (a) No claim may be made by the Buyer or any of its Affiliates as
Indemnified Party pursuant to Section 10.1.1 after the first to occur of (i) the
delivery by the Company's independent auditors of their report on the financial
statements of the Buyer, which statements shall include the assets and results
of operations of the Company, for the year ended December 31, 1996 and (ii) the
first anniversary of the Closing Date (hereinafter referred to as the "CutOff
Date"), except for Buyer's Reserved Claims. "Buyer's Reserved Claims" shall mean
(i) all claims as to which such Indemnified Party has given any Indemnifying
Party written notice on or prior to the Cut-Off Date and (ii) all claims under
Section 10.1.1 to the extent they result from a misrepresentation or inaccuracy
in a statement made in Section 5.3 hereof. Claims in respect of Buyer's Reserved
Claims may be made at any time subject to the statute of limitations applicable
thereto.

         (b) The Shareholders shall not have any obligation under Section 10.1.1
hereof to indemnify the Buyer in respect of any Loss incurred due to any
inaccuracy in or the breach of any representation and warranty contained in any
Section hereof (other than Section 5.3, until the total of all such Losses
incurred by the Buyer (excluding Losses incurred in respect of the
representations and warranties contained in Section 5.3 hereof) exceeds (i) with
respect to all matters except breaches of the representations and warranties
that relate to Inventory, $250,000, whereupon the Buyer shall be entitled to
indemnification hereunder for the entire amount of all such Losses (excluding
Losses incurred in respect of the representations and warranties contained in
Section 5.3 hereof) in excess of $250,000 and (ii) with respect to breaches of
the representations and warranties that relate to Inventory, $50,000, whereupon
the Buyer shall be entitled to indemnification hereunder for the entire amount
of all such Losses in excess of $50,000; provided, however, that if Buyer has
not taken a physical


                                      -27-
<PAGE>   36
inventory of such Inventory on or before 30 days after the Closing Date, Buyer
shall not be entitled to such indemnification hereunder. The Shareholders shall
be obligated under Section 10.1.1 hereof to indemnify the Buyer in respect of
any Loss incurred due to any inaccuracy in or the breach of any representation
and warranty contained in Section 5.3 hereof. Notwithstanding the foregoing, and
subject to Section 10.3(e), the aggregate maximum recovery in respect of all
Losses incurred by the Buyer under this Section 10.3(b) shall not exceed the
value of the shares of Buyer Common Stock deposited in escrow pursuant to the
General Escrow Agreement by the Shareholders pursuant to Section 3.5 hereof.

         (c) No claim may be made by any Shareholder as Indemnified Party
pursuant to Section 10.1.3 after the Cut-Off Date, except for Shareholders'
Reserved Claims. "Shareholders' Reserved Claims" shall mean all claims as to
which such Indemnified Party has given any Indemnifying Party written notice on
or prior to the Cut-Off Date. Claims in respect of Shareholders' Reserved Claims
may be made at any time subject to the statute of limitations applicable
thereto.

         (d) The Buyer shall not have any obligation under Section 10.1.3 to
indemnify any Shareholder in respect of any Loss until the aggregate combined
total of all Losses incurred by all Shareholders exceeds $250,000, whereupon the
Stockholders shall be entitled to indemnification hereunder for the entire
aggregate cumulative amount of all such Losses in excess of $250,000, up to an
aggregate maximum recovery in respect of such Losses of $4,000,000.

         (e) None of the foregoing limitations provided in this Section 10.3
shall apply to the indemnification obligations of the Shareholders pursuant to
Section 10.1.2; provided that the aggregate maximum recovery in respect of all
Losses incurred by the Buyer under Section 10.1.2 shall not exceed the value of
the shares of Buyer Common Stock deposited in escrow pursuant to the Litigation
Escrow Agreement by the Shareholders pursuant to Section 3.5 hereof.

         (f) This Section 10 provides the exclusive rights and remedies of the
parties with respect to Losses after Closing, all other remedies at law or in
equity being waived by the parties. Without limiting the foregoing, no
Shareholder shall have any right of contribution against the Company with
respect to Losses resulting from the breach of any of the representations and
warranties of the Company made herein, or with respect to the failure by the
Company to perform any covenants required to be performed by the Company
pursuant to this Agreement.

         (g) Any amounts payable under this Section 10 as indemnification for
any Loss shall be paid solely in Buyer Common Stock, which shall be valued at a
price per share equal to the Average Price, regardless of the actual fair market
value on the date the claim is settled.

mutual written consent at any time prior to the Closing.

         (b) The Buyer may terminate this Agreement by giving written notice to
the Shareholders at any time prior to the Closing in the event there has been a
material breach of any representation or warranty made by the Shareholders or
the Company in this Agreement (including without limitation the Exhibits hereto)
(as each such representation or warranty would read if all qualifications as to
materiality (including without limitation in the definition of Material Adverse
Effect) or knowledge were deleted therefrom) or a material breach or material
violation by the Shareholders or the Company of any covenant or agreement made
in or any duty with respect to this Agreement (including without limitation the
Exhibits hereto).

         (c) The Shareholders may terminate this Agreement by giving written
notice to the Buyer at any time prior to the Closing in the event there has been
a material breach of any representation or warranty made by the Buyer in this
Agreement (including without limitation the Exhibits hereto) (as each such

(including without limitation in the definition of Material Adverse Effect) or

Agreement (including without limitation the Exhibits hereto).

         (d) The Buyer may terminate this Agreement by giving written notice to

                                      -34-
<PAGE>   43
the Closing if the Closing shall not have occurred on or before the Final
Termination Date by reason of the failure of any condition set forth in Section
8 to be satisfied (unless the failure results primarily from one or more
breaches or violations of this Agreement by the Buyer or inaccuracies in
representations of the Buyer hereunder).

         (e) The Shareholders may terminate this Agreement by giving written
notice to the Buyer at any time on or after the Final Termination Date but prior
to the Closing if the Closing shall not have occurred on or before the Final
Termination Date by reason of the failure of any condition set forth in Section

breaches or violations of this Agreement by the Shareholders or the Company or
inaccuracies in representations of the Shareholders or the Company hereunder).

         13.2. Effect of Termination. In the event of the termination of this
Agreement pursuant to Section 13.1, all obligations of the parties hereunder
shall terminate without any liability of any party to any other party; provided,
however, that no termination of this Agreement shall relieve any party of
liabilities in respect of any breaches or violations of this Agreement or any
duty with respect hereto by such party or any inaccuracies in any
representations by such party hereunder prior to termination.

14.      SECURITIES ACT AND POOLING RESTRICTIONS

         14.1. Shares not Registered. The Shareholders acknowledge that the
Buyer Common Stock to be delivered to the Shareholders pursuant to this
Agreement has not and will not be registered under the 1933 Act and may not be
resold except pursuant to an effective registration statement under the 1933 Act
or pursuant to an exemption from registration. Except for and subject to Section
15, the Buyer Common Stock to be acquired by the Shareholders pursuant to this
Agreement is being acquired solely for their own account, for investment
purposes only, with no present intention of distributing, selling or otherwise
disposing of it in connection with a distribution.

         14.2. Economic Risk; Sophistication. The Shareholders are able to bear
the economic risk of an investment in the Buyer Common Stock acquired pursuant
to this Agreement and can afford to sustain a total loss on such investment and
have such knowledge and experience in financial and business matters that they
are capable of evaluating the merits and risks of the proposed investment and
therefore have the capacity to protect their own interests in connection with
the acquisition of the Buyer Common Stock. The Shareholders have had an adequate
opportunity to ask questions and receive answers from the officers of the Buyer
concerning any and all matters relating to the business, operations and
prospectus of the Buyer. The Shareholders have asked any and all questions in
the nature described in the preceding sentence and all questions have been
answered to their satisfaction.


                                      -35-
<PAGE>   44
         14.3. Restrictions on Resale; Legends. The Shareholders covenant and
agree that they will not offer, sell, assign, pledge, hypothecate, transfer or
otherwise dispose of the Buyer Common Stock to be acquired by them pursuant to
this Agreement except after full compliance with all of the applicable
provisions of the 1933 Act and the rules and regulations promulgated by the SEC
thereunder. The certificates of Buyer Common Stock issued pursuant to the Merger
shall bear the following legend until such time as the registration statement
relating thereto has been declared effective by the SEC:

         THE SHARES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE
         SECURITIES ACT OF 1933 AND MAY ONLY BE SOLD OR OTHERWISE TRANSFERRED IF
         THE HOLDER HEREOF COMPLIES WITH THE PROVISIONS OF SUCH ACT.

         14.4. Restrictions on Transfer of Common Stock and Buyer Common Stock.
Until the publication by Buyer of financial results which include at least 30
days of combined results of operations of Buyer and the Company, the
Shareholders covenant and agree with Buyer that they will not, without the prior
written consent of Buyer, transfer, sell, assign, pledge, hypothecate, give,
create a security interest in or lien on, place in trust, assign or in any other
way encumber or dispose of, directly or indirectly and whether or not by
operation of law or for value ("Transfer"), any shares of Common Stock or Buyer
Common Stock, except for (a) a Transfer between a Shareholder and such
Shareholder's spouse or children, or trust for the benefit of any of them, or
(b) a Transfer between a Shareholder and such Shareholder's guardian or
conservator and, upon the death of such Shareholder, such Shareholder's
executor, administrator and heirs. Buyer agrees to file in a timely manner all
reports it is required to file under the 1934 Act.

15.      REGISTRATION RIGHTS.

         15.1. General. Prior to the Closing, Buyer shall file (and shall use
its reasonable efforts to cause to become effective as soon as practicable
following the date on which Buyer makes publicly available financial results
covering at least 30 days of post-Merger combined operations of Buyer and the
Company) a registration statement on Form S-3 under the 1933 Act, covering the
Registrable Securities. As used herein, the term "Registrable Securities" shall
mean the shares of Buyer Common Stock issued to the Shareholders in connection
with the Merger; provided, however, that once issued, such shares of Buyer
Common Stock and other securities shall cease to be Registrable Securities when
(x) a registration statement with respect to the sale of such securities shall
have become effective under the 1933 Act and such securities shall have been
disposed of in accordance with such registration statement, (y) they shall have
been sold pursuant to Rule 144 promulgated under the 1933 Act ("Rule 144"), or
(z) they shall have ceased to be outstanding.


                                      -36-
<PAGE>   45
         15.2. Expenses. Buyer or the Company shall pay all expenses incident to
Buyer's performance of or compliance with its obligations under this Section 15
to effect the registration of Registrable Securities required hereunder,
including, without limitation, all registration, filing, and listing fees, all
registration, filing, qualification and other fees and expenses of complying
with securities or blue sky laws, all word processing, duplicating and printing
expenses, messenger, shipping and delivery expenses, the fees and disbursement
of counsel for the Company and of its independent public accountants, and any
legal fees and expenses of up to $10,000 of counsel retained by the
Shareholders, and further excluding any fees and disbursement of underwriters,
underwriting discounts and commissions and transfer taxes, if any, in respect of
Registrable Securities, which fees, expenses, discounts, commissions and taxes
in respect of Registrable Securities shall be payable by the holders thereof (in
the case of an underwritten offering and the underwriter's fees, expenses,
discounts or commissions, pro rata among such holders in proportion to the
number of Registrable Securities being sold by them). Buyer will use reasonable
efforts to effect the registration of such Registrable Securities in accordance
with any intended method of disposition thereof specified in writing by holders
of a majority of the Registrable Securities.

         15.3. Further Obligations. Without limiting the foregoing, Buyer will:

         (a) prepare and file with the SEC, the registration statements on Form
S-3 to effect such registrations (including such audited financial statements as
may be required by the 1933 Act) and use its reasonable efforts to cause such
registration statement to become effective in the time frame outlined in Section
15.1; provided, that as far in advance as practical before filing such
registration statement or any amendment thereto, and in any event at least five
(5) days prior to any such filing, Buyer will furnish to the Shareholders copies
of reasonably complete drafts of all such documents proposed to be filed
(including any registration statement and including exhibits), and any
Shareholder shall have the opportunity to object to any information pertaining
solely to such holder that is contained therein and Buyer will make the
corrections reasonably requested by such Shareholders with respect to such
information prior to filing any such registration statement or amendment;

         (b) prepare and file with the SEC such amendments and supplements to
such registration statements and any prospectus used in connection therewith as
may be necessary to maintain the effectiveness of such registration statements
and to comply in all material respects with the requirements of the 1933 Act
with respect to the disposition of all Registrable Securities included in such
registration statement, in accordance with the intended methods of disposition
thereof, until the earlier of (i) such time as all of such securities have been
disposed of in accordance with the intended methods of disposition by the seller
or sellers thereof set forth in such registration statement or (ii) two years
after the Closing Date, and in the event that any Registrable Securities remain
unsold at the end of such period, Buyer may file a post-effective amendment to
the registration statement for the purpose of removing such Registrable
Securities from registered status;


                                      -37-
<PAGE>   46
         (c) promptly notify each holder of Registrable Securities and the
underwriter or underwriters, if any:

                  (i) when such registration statement or any prospectus used in
         connection therewith, or any amendment or supplement thereto, has been
         filed and, with respect to such registration statement or any
         post-effective amendment thereto, when the same has become effective;

                  (ii) of any written request by the SEC for amendments or
         supplements to such registration statement or prospectus or for
         supplemental information;

                  (iii) of the notification to Buyer by the SEC of its
         initiation of any proceeding with respect to the issuance by the SEC
         of, or of the issuance by the SEC of, any stop order suspending the
         effectiveness of such registration statement; and

                  (iv) of the receipt by Buyer of any notification with respect
         to the suspension of the qualification of any Registrable Securities
         for sale under the applicable securities or blue sky laws of any
         jurisdiction;

         (d) furnish to each holder of Registrable Securities included in the
registration statement such number of conformed copies of the registration
statement and of each amendment and supplement thereto (in each case including
all exhibits and documents incorporated by reference), such number of copies of
the prospectus contained in such registration statement (including each
preliminary prospectus and any prospectus supplement) and any other prospectus
filed under Rule 424 promulgated under the 1933 Act relating to such holder's
Registrable Securities, and such other documents, as such seller may reasonably
request to facilitate the disposition of such holder's Registrable Securities;

         (e) use its reasonable best efforts to register or qualify or receive
an exemption for all Registrable Securities included in the registration
statement under such other securities or blue sky laws of such jurisdictions as
each holder thereof shall reasonably request which request is made within ten
(10) days following the original filing of the registration statement and to
keep such registration or qualification in effect for so long as the
registration statement remains in effect, and take any other action which may be
reasonably necessary or advisable to enable such holder to consummate the
disposition in such jurisdictions of the Registrable Securities owned by such
holder, except that Buyer shall not for any such purpose be required (i) to
qualify generally to do business as a foreign corporation in any jurisdiction
wherein it would not but for the requirements of this paragraph (e) be obligated
to be so qualified, (ii) to consent to general service of process in any such
jurisdiction or (iii) to subject itself to taxation in any such jurisdiction by
reason of such registration or qualification; and

         (f) use all reasonable efforts to obtain withdrawal of any order
suspending the effectiveness of a registration statement, or the lifting of any
suspension of qualification (or


                                      -38-
<PAGE>   47
exemption from qualification) of the offer and sale of any of the Registration
Securities in any jurisdiction.

         Buyer may require each Shareholder whose Registrable Securities are
being registered to, and each such holder as a condition to including
Registrable Securities in such registration shall, furnish Buyer and any
underwriters with such information and affidavits regarding such holder and the
distribution of such securities as Buyer and such underwriters may from time to
time reasonably request in writing and to otherwise cooperate in connection with
such registration. At any time during the effectiveness of the registration
statement covering Registrable Securities offered by a holder, if such holder
becomes aware of any change materially affecting the accuracy of the information
contained in such registration statement or the prospectus (as then amended or
supplemented) relating to such holder, it will immediately notify Buyer of such
change.

         Upon receipt of any notice from Buyer of the existence of any facts as
a result of which any prospectus included in such registration statement, as
then in effect, includes an untrue statement of a material fact or omits to
state any material fact required to be stated therein or necessary to make the
statements therein, in the light of the circumstances under which they were
made, not misleading, each holder of Registrable Securities will forthwith
discontinue such holder's disposition of Registrable Securities pursuant to the
registration statement until such Holder receives copies of a supplemented or
amended prospectus from Buyer and, if so directed by Buyer, shall deliver to
Buyer (at Buyer's expense) all copies, other than permanent file copies, then in
such holder's possession of the prospectus relating to such Registrable
Securities current at the time of receipt of such notice. If requested by Buyer,
the Shareholders shall not effect any sales using the prospectus for a period
not to exceed 180 days if, in the good faith determination of Buyer's board of
directors, premature disclosure of any information that would be required to be
included in the prospectus would be detrimental to the Buyer. In the event Buyer
shall give any such notice, the period referred to in paragraph (b) of this
Section 15.3 shall be extended by a number of days equal to the number of days
during the period from the giving of such notice from Buyer to stop trading to
the date when the copies of the supplemented or amended prospectus are sent to
holders whose Registrable Securities are included in such registration
statement.

         15.4. Indemnification.

         (a) Buyer shall, to the full extent permitted by law, indemnify and
hold harmless each seller of Registrable Securities included in the registration
statement filed pursuant to this Section 15, its directors, officers, and
partners, and each other Person, if any, who controls any such seller within the
meaning of the 1933 Act, against any Losses to which such seller or any such
director, officer, partner or controlling Person may become subject under the
1933 Act or otherwise, insofar as such losses, claims, damages or liabilities
(or actions in respect thereof) arise out of or are based upon any untrue
statement of any material fact contained in such registration statement, any
preliminary prospectus, final prospectus or prospectus


                                      -39-
<PAGE>   48
supplement contained therein or filed with the Commission, or any amendment or
supplement thereto, or any omission to state therein a material fact required to
be stated therein or necessary to make the statements therein (in the case of a
prospectus, in the light of the circumstances under which they were made) not
misleading; provided, that Buyer shall not be liable in any such case to the
extent that any such loss, claim, damage or liability (or action in respect
thereof) arises out of or is based upon an untrue statement or alleged untrue
statement or omission or alleged omission made in any such registration
statement, preliminary prospectus, final prospectus, amendment or supplement in
reliance upon and in conformity with information furnished to Buyer by such
seller. Such indemnity shall remain in full force and effect regardless of any
investigation made by or on behalf of such seller or any such director, officer,
partner or controlling Person, and shall survive the transfer of such securities
by such seller.

         (b) Each Person whose Registrable Securities are included or are to be
included in the registration statement filed pursuant to this Section 15, as a
condition to including such holder's Registrable Securities in each registration
statement, shall, to the full extent permitted by law, indemnify and hold
harmless Buyer, its directors and officers, and each other Person, if any, who
controls Buyer within the meaning of the 1933 Act, against any Losses to which
Buyer or any such director or officer or controlling Person may become subject
under the 1933 Act or otherwise, insofar as such losses, claims, damages or
liabilities (or actions in respect thereof) arise out of or are based upon any
untrue statement of any material fact contained in any such registration
statement, any preliminary prospectus, final prospectus or prospectus supplement
contained therein or filed with the Commission, or any amendment or supplement
thereto, or any omission to state therein a material fact required to be stated
therein or necessary to make the statements therein (in the case of a
prospectus, in the light of the circumstances under which they were made) not
misleading, if such untrue statement or omission was made in reliance upon and
in conformity with written information furnished to Buyer by such seller
specifically stating that it is for use in the preparation of such registration
statement, preliminary prospectus, final prospectus, amendment or supplement;
provided, however, that the obligation to provide indemnification pursuant to
this Section 15 shall be several, and not joint and several, among such
indemnifying parties on the basis of the number of Registrable Securities of
each such indemnifying party included in such registration statement.
Notwithstanding any contrary provision of Section 10, the indemnification
obligation of the Shareholders under this Section 15 shall in no way be limited
to (and Buyer shall not be constrained to seek in response to any failure to
provide indemnity pursuant to this Section 15) recourse against Buyer Common
Stock held by the Escrow Agent. The foregoing indemnity shall remain in full
force and effect regardless of any investigation made by or on behalf of Buyer
or any such director, officer or controlling Person and shall survive the
transfer of such securities by such seller. Such holders shall also indemnify
each other Person who participates (including as an underwriter) in the offering
or sale of Registrable Securities, their officers and directors and each other
Person, if any, who controls any such participating Person within the meaning of
the 1933 Act to the same extent as provided above with respect to Buyer.


                                      -40-
<PAGE>   49
         (c) Promptly after receipt by any party of notice of the commencement
of any action or proceeding involving a claim referred to in the preceding
paragraph (a) or (b) of this Section 15.4, such party shall, if a claim in
respect thereof is to be made against another party pursuant to such paragraphs,
give written notice to the latter of the commencement of such action, provided
that any failure of any Person to give notice as provided herein shall not
relieve any other Person of its obligations under the preceding paragraph of
this Section 15.4, except to the extent that such other Person is actually
prejudiced by such failure. In case any such action is brought, the party
obligated to indemnify pursuant to the foregoing provisions of this Section 15.4
shall be entitled to participate in and, unless, in the reasonable judgment of
any indemnified party, a conflict of interest between such indemnified party and
any indemnifying party exists with respect to such claim, to assume the defense
thereof, jointly with any other indemnifying party similarly notified to the
extent that it may wish, with counsel reasonably satisfactory to such
indemnified party, and after notice from the indemnifying party to such
indemnified party of its election so to assume the defense thereof, the
indemnifying party shall not be liable to such indemnified party for any legal
or other expenses subsequently incurred by the latter in connection with the
defense thereof other than reasonable costs of investigation; provided that the
indemnified party may participate in such defense at the indemnified party's
expense. No indemnifying party shall consent to entry of any judgment or enter
into any settlement which does not include as an unconditional term thereof the
giving by the claimant or plaintiff to each indemnified party of a release from
all liability in respect to such claim or litigation without the consent of the
indemnified party. No indemnifying party shall be subject to any liability for
any settlement made without its consent, which consent shall not be unreasonably
withheld.

         (d) If the indemnity and reimbursement obligation provided for in any
paragraph of this Section 15.4 is unavailable or insufficient to hold harmless a
party entitled to indemnification hereunder in respect of any losses, claims,
damages or liabilities (or actions with respect thereto) referred to therein,
the party obligated to indemnify hereunder shall contribute to the amount paid
or payable by the indemnified party as a result of such losses, claims, damages
or liabilities (or actions) in such proportion as is appropriate to reflect the
relative fault of the indemnifying party on the one hand and the indemnified
party on the other hand in connection with statements or omissions which
resulted in such losses, claims, damages or liabilities, as well as any other
relevant equitable considerations. Relative fault shall be determined by
reference to, among other things, whether the untrue or alleged untrue statement
of a material fact or the omission or alleged omission to state a material fact
relates to information supplied by the indemnifying party or the indemnified
party and the parties' relative intent, knowledge, access to information and
opportunity to correct or prevent such untrue statement or omission. The parties
hereto agree that it would not be just and equitable if contributions pursuant
to this paragraph were to be determined by pro rata allocation or by any other
method of allocation which does not take account of the equitable considerations
referred to in the first sentence of this paragraph. No Person guilty of
fraudulent


                                      -41-
<PAGE>   50
misrepresentation (within the meaning of Section 11(f) of the 1933 Act) shall be
entitled to contribution from any Person not guilty of such fraudulent
misrepresentation.
