                 AGREEMENT AND PLAN OF MERGER AND REORGANIZATION


        THIS AGREEMENT AND PLAN OF MERGER AND REORGANIZATION ("AGREEMENT") is
made and entered into as of June 7, 2000, by and among: MOLECULAR DEVICES
CORPORATION, a Delaware corporation ("PARENT"); MERCURY ACQUISITION SUB, INC., a
Delaware corporation and a wholly owned subsidiary of Parent ("MERGER SUB"); and
LJL BIOSYSTEMS, INC., a Delaware corporation (the "COMPANY"). Certain
capitalized terms used in this Agreement are defined in Exhibit A.

                                    RECITALS

        A. Parent, Merger Sub and the Company intend to effect a merger of
Merger Sub into the Company in accordance with this Agreement and the Delaware
General Corporation Law (the "MERGER"). Upon consummation of the Merger, Merger
Sub will cease to exist, and the Company will become a wholly owned subsidiary
of Parent.

        B. It is intended that the Merger qualify as a tax-free reorganization
within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as
amended (the "CODE"). For financial reporting purposes, it is intended that the
Merger be accounted for as a "pooling of interests."

        C. The respective boards of directors of Parent, Merger Sub and the
Company have approved this Agreement and approved the Merger.

        D. In order to induce Parent to enter into this Agreement and to
consummate the Merger, certain stockholders of the Company are entering into
Voting Agreements pursuant to which they are agreeing to vote in favor of the
adoption and approval of this Agreement and the approval of the Merger. In order
to induce the Company to enter into this Agreement and to consummate the Merger,
certain stockholders of Parent are entering into Voting Agreements pursuant to
which they are agreeing to vote in favor of the issuance of Parent Common Stock
in connection with the Merger.

                                    AGREEMENT

        The parties to this Agreement, intending to be legally bound, agree as
follows:

        SECTION 1. DESCRIPTION OF TRANSACTION

            1.1 MERGER OF MERGER SUB INTO THE COMPANY. Upon the terms and
subject to the conditions set forth in this Agreement, at the Effective Time (as
defined in Section 1.3), Merger Sub shall be merged with and into the Company,
and the separate existence of Merger Sub shall cease. The Company will continue
as the surviving corporation in the Merger (the "SURVIVING CORPORATION").

            1.2 EFFECT OF THE MERGER. The Merger shall have the effects set
forth in this Agreement and in the applicable provisions of the Delaware General
Corporation Law (the "DGCL").

            1.3 CLOSING; EFFECTIVE TIME. The consummation of the transactions
contemplated by this Agreement (the "CLOSING") shall take place at the offices
of Cooley Godward LLP, located at Five Palo Alto Square, 3000 El Camino Real,
Palo Alto, California, at 10:00 a.m. on a date to be designated by Parent (the
"CLOSING DATE"), which shall be no later than the second business day after the
satisfaction or waiver of the conditions set forth in Sections 6 and 7.
Contemporaneously with or as promptly as practicable after the Closing, the
parties hereto shall cause a properly executed certificate of merger

   8


conforming to the requirements of the DGCL (the "CERTIFICATE OF MERGER") to be
filed with the Secretary of State of the State of Delaware. The Merger shall
take effect at the time the Certificate of Merger is filed with the Secretary of
State of the State of Delaware or at such later time as may be specified in the
Certificate of Merger (the "EFFECTIVE TIME").

            1.4 CERTIFICATE OF INCORPORATION AND BYLAWS; DIRECTORS AND OFFICERS.
Unless otherwise determined by Parent prior to the Effective Time:

               (a) the Certificate of Incorporation of the Surviving Corporation
        shall be amended and restated as of the Effective Time to substantially
        conform to the Certificate of Incorporation of Merger Sub as in effect
        immediately prior to the Effective Time;

               (b) the Bylaws of the Surviving Corporation shall be amended and
        restated as of the Effective Time to substantially conform to the Bylaws
        of Merger Sub as in effect immediately prior to the Effective Time; and

               (c) the directors and officers of the Surviving Corporation
        immediately after the Effective Time shall be the respective individuals
        who are directors and officers of Merger Sub immediately prior to the
        Effective Time.

            1.5 CONVERSION OF SHARES.

                (a) Subject to the other subsections of this Section 1.5, at the
Effective Time, by virtue of the Merger and without any further action on the
part of Parent, Merger Sub, the Company or any stockholder of the Company:

                   (i) any shares of Company Common Stock then held by the
        Company or any Subsidiary of the Company (or held in the Company's
        treasury) shall be canceled and retired and shall cease to exist at the
        Effective Time, and no consideration shall be delivered in exchange
        therefor;

                   (ii) any shares of Company Common Stock then held by Parent,
        Merger Sub or any other Subsidiary of Parent shall be canceled and
        retired and shall cease to exist at the Effective Time, and no
        consideration shall be delivered in exchange therefor;

                   (iii) each share of the common stock, $0.001 par value per
        share, of Merger Sub then outstanding shall be converted into one share
        of common stock of the Surviving Corporation; and

                   (iv) except as provided in clauses "(i)" and "(ii)" of this
        sentence, each share of Company Common Stock then outstanding shall be
        converted into the right to receive 0.30 of a share of Parent Common
        Stock (the "EXCHANGE RATIO").

                (b) If, between the date of this Agreement and the Effective
Time, the outstanding shares of Company Common Stock or Parent Common Stock are
changed into a different number or class of shares by reason of any stock split,
division or subdivision of shares, stock dividend, reverse stock split,
consolidation of shares, reclassification, recapitalization or other similar
transaction, then the Exchange Ratio shall be appropriately adjusted.

                (c) If any shares of Company Common Stock outstanding
immediately prior to the Effective Time are unvested or are subject to a
repurchase option, risk of forfeiture or other condition


                                       2.
   9

under any applicable restricted stock purchase agreement or other agreement with
the Company or under which the Company has any rights, then the shares of Parent
Common Stock issued in exchange for such shares of Company Common Stock will
also be unvested and subject to the same repurchase option, risk of forfeiture
or other condition, and the certificates representing such shares of Parent
Common Stock may accordingly be marked with appropriate legends. The Surviving
Corporation shall take all action that may be necessary to ensure that, from and
after the Effective Time, Parent is entitled to exercise any such repurchase
option or other right set forth in any such restricted stock purchase agreement
or other agreement.

                (d) No fractional shares of Parent Common Stock shall be issued
in connection with the Merger, and no certificates or scrip for any such
fractional shares shall be issued. Any holder of Company Common Stock who would
otherwise be entitled to receive a fraction of a share of Parent Common Stock
(after aggregating all fractional shares of Parent Common Stock issuable to such
holder) shall, in lieu of such fraction of a share and, upon surrender of such
holder's Company Stock Certificate(s) (as defined in Section 1.6) be paid in
cash the dollar amount (rounded to the nearest whole cent), without interest,
determined by multiplying such fraction by the closing sales price of a share of
Parent Common Stock as reported on the Nasdaq National Market on the second day
preceding the Closing Date.

            1.6 CLOSING OF THE COMPANY'S TRANSFER BOOKS. At the Effective Time:
(a) all shares of Company Common Stock outstanding immediately prior to the
Effective Time shall automatically be canceled and retired and shall cease to
exist, and all holders of certificates representing shares of Company Common
Stock that were outstanding immediately prior to the Effective Time shall cease
to have any rights as stockholders of the Company; and (b) the stock transfer
books of the Company shall be closed with respect to all shares of Company
Common Stock outstanding immediately prior to the Effective Time. No further
transfer of any such shares of Company Common Stock shall be made on such stock
transfer books after the Effective Time. If, after the Effective Time, a valid
certificate previously representing any shares of Company Common Stock (a
"COMPANY STOCK CERTIFICATE") is presented to the Exchange Agent (as defined in
Section 1.7) or to the Surviving Corporation or Parent, such Company Stock
Certificate shall be canceled and shall be exchanged as provided in Section 1.7.

            1.7 EXCHANGE OF CERTIFICATES.

                (a) EquiServe, L.P. or such other reputable bank or trust
company selected by Parent prior to the Closing Date shall act as exchange agent
in the Merger (the "EXCHANGE AGENT"). As soon as practicable after the Effective
Time, Parent shall deposit with the Exchange Agent (i) certificates representing
the shares of Parent Common Stock issuable pursuant to this Section 1, and (ii)
cash sufficient to make payments in lieu of fractional shares in accordance with
Section 1.5(e). The shares of Parent Common Stock and cash amounts so deposited
with the Exchange Agent, together with any dividends or distributions received
by the Exchange Agent with respect to such shares, are referred to collectively
as the "EXCHANGE FUND."

                (b) As soon as reasonably practicable after the Effective Time,
the Exchange Agent will mail to the record holders of Company Stock Certificates
(i) a letter of transmittal in customary form and containing such provisions as
Parent and the Company may reasonably specify (including a provision confirming
that delivery of Company Stock Certificates shall be effected, and risk of loss
and title to Company Stock Certificates shall pass, only upon delivery of such
Company Stock Certificates to the Exchange Agent), and (ii) instructions for use
in effecting the surrender of Company Stock Certificates in exchange for
certificates representing Parent Common Stock. Upon surrender of a Company Stock
Certificate to the Exchange Agent for exchange, together with a duly executed

the holder of such Company Stock Certificate that does not perfect its
dissenters' rights, if any, shall be entitled to receive in exchange therefor a
certificate representing the number of whole shares of Parent Common Stock that
such holder has the right to receive pursuant to the provisions of Section 1.5
(and cash in lieu of any fractional share of Parent Common Stock), and (2) the
Company Stock Certificate so surrendered shall be canceled. In the event of a
transfer of ownership of Company Common Stock which is not registered in the
transfer records of the Company, a certificate representing the proper number of
shares of Parent Common Stock may be issued to a transferee if the Company Stock
Certificate is presented to the Exchange Agent, accompanied by all documents
required to evidence and effect such transfer and by evidence that any
applicable stock transfer taxes have been paid. Until surrendered as
contemplated by this Section 1.7(b), each Company Stock Certificate shall be
deemed, from and after the Effective Time, to represent only the right to
receive shares of Parent Common Stock (and cash in lieu of any fractional share
of Parent Common Stock) as contemplated by Section 1. If any Company Stock
Certificate shall have been lost, stolen or destroyed, Parent may, in its
discretion and as a condition precedent to the issuance of any certificate
representing Parent Common Stock, require the owner of such lost, stolen or
destroyed Company Stock Certificate to provide an appropriate affidavit and to
deliver a bond (in such sum as Parent may reasonably direct) as indemnity
against any claim that may be made against the Exchange Agent, Parent or the
Surviving Corporation with respect to such Company Stock Certificate.

                (c) No dividends or other distributions declared or made with
respect to Parent Common Stock with a record date after the Effective Time shall
be paid to the holder of any unsurrendered Company Stock Certificate with
respect to the shares of Parent Common Stock which such holder has the right to
receive upon surrender thereof until such holder surrenders such Company Stock
Certificate in accordance with this Section 1.7 (at which time such holder shall
be entitled, subject to the effect of applicable escheat or similar laws, to
receive all such dividends and distributions, without interest).

                (d) Any portion of the Exchange Fund that remains undistributed
to holders of Company Stock Certificates as of the date 360 days after the date
on which the Merger becomes effective shall be delivered to Parent upon demand,
and any holders of Company Stock Certificates who have not theretofore
surrendered their Company Stock Certificates in accordance with this Section 1.7
shall thereafter look only to Parent for satisfaction of their claims for Parent
Common Stock, cash in lieu of fractional shares of Parent Common Stock and any
dividends or distributions with respect to Parent Common Stock.

                (e) Each of the Exchange Agent, Parent and the Surviving
Corporation shall be entitled to deduct and withhold from any consideration
payable or otherwise deliverable pursuant to this Agreement to any holder or
former holder of Company Common Stock such amounts as may be required to be
deducted or withheld therefrom under the Code or any provision of state, local
or foreign tax law or under any other applicable Legal Requirement. To the
extent such amounts are so deducted or withheld, such amounts shall be treated
for all purposes under this Agreement as having been paid to the Person to whom
such amounts would otherwise have been paid.

                (f) Neither Parent nor the Surviving Corporation shall be liable
to any holder or former holder of Company Common Stock or to any other Person
with respect to any shares of Parent Common Stock (or dividends or distributions
with respect thereto), or for any cash amounts, delivered to any public official
pursuant to any applicable abandoned property law, escheat law or similar Legal
Requirement.

            1.9 DISSENTING SHARES.  Notwithstanding anything to the contrary
contained in this Agreement, any shares of capital stock of the Company that, as
of the Effective Time, are or may become "dissenting shares" within the meaning
of Section 1300(b) of the California General Corporation Law, if applicable,
shall not be converted into or represent the right to receive Parent Common
Stock in accordance with Section 1.5 (or cash in lieu of fractional shares in
accordance with Section 1.5(d)), and the holder or holders of such shares shall
be entitled only to such rights as may be granted to such holder or holders in
the California General Corporation Law; provided, however, that if the status of
any such shares as "dissenting shares" shall not be perfected, or if any such
shares shall lose their status as "dissenting shares," then, as of the later of
the Effective Time or the time of the failure to perfect such status or the loss
of such status, such shares shall automatically be converted into and shall
represent only the right to receive (upon the surrender of the certificate or
certificates representing such shares) Parent Common Stock in accordance with
Section 1.5 (and cash in lieu of fractional shares in accordance with Section
1.5(d)).

            1.10 RESERVED.

            1.11 TAX CONSEQUENCES. For federal income tax purposes, the Merger
is intended to constitute a reorganization within the meaning of Section 368 of
the Code. The parties to this Agreement hereby adopt this Agreement as a "plan
of reorganization" within the meaning of Sections 1.368-2(g) and 1.368-3(a) of
the United States Treasury Regulations.

            1.12 ACCOUNTING CONSEQUENCES. For financial reporting purposes, the
Merger is intended to be accounted for as a "pooling of interests."

            1.13 FURTHER ACTION. If, at any time after the Effective Time, any
further action is determined by Parent to be necessary or desirable to carry out
the purposes of this Agreement or to vest the Surviving Corporation with full
right, title and possession of and to all rights and property of Merger Sub and
the Company, the officers and directors of the Surviving Corporation and Parent
shall be fully authorized (in the name of Merger Sub, in the name of the Company
and otherwise) to take such action.

registration or application. Part 2.9(a)(ii) of the Company Disclosure Schedule
identifies and provides a brief description of all other Proprietary Assets
owned by the Acquired Corporations that are material to the business of the
Acquired Corporations. Part 2.9(a)(iii) of the Company Disclosure Schedule
identifies any Acquired Company Contract containing any ongoing royalty or
payment obligations in excess of $10,000 with respect to, each Proprietary Asset
that is licensed or otherwise made available to the Acquired Corporations by any

any Proprietary Asset that is licensed to the Acquired Corporations under any
third party software license generally available to the public), and identifies
the Contract under which such Proprietary Asset is being licensed or otherwise
made available to such Acquired Corporation. The Acquired Corporations have
good, valid and marketable title to all of the Acquired Corporation Proprietary
Assets identified in Parts 2.9(a)(i) and 2.9(a)(ii) of the Company Disclosure
Schedule, free and clear of all Encumbrances, except for (i) any lien for
current taxes not yet due and payable, and (ii) minor liens that have arisen in
the ordinary course of business and that do not (individually or in the
aggregate) materially detract from the value of the assets subject thereto or
materially impair the operations of either of the Acquired Corporations. The
Acquired Corporations have a valid right to use, license and otherwise exploit
all Proprietary Assets identified in Part 2.9(a)(iii) of the Company Disclosure
Schedule. None of the Acquired Corporations has developed jointly with any other
Person any Acquired Corporation Proprietary Asset that is material to the
business of the Acquired Corporations with respect to which such other Person
has any rights. Except as set forth in Part 2.9(a)(v) of the Company Disclosure
Schedule, there is no Acquired Corporation Contract (with the exception of end
user license agreements in the form previously delivered by the Company to
Parent) pursuant to which any Person has any right (whether or not currently
exercisable) to use, license or otherwise exploit any Acquired Corporation
Proprietary Asset.

                (b) The Acquired Corporations have taken reasonable measures and
precautions to protect and maintain the confidentiality, secrecy and value of
all material Acquired Corporation Proprietary Assets (except Acquired
Corporation Proprietary Assets whose value would be unimpaired by disclosure).
Without limiting the generality of the foregoing, (i) all current and former
employees of the Acquired Corporations who are or were involved in, or who have
contributed to, the creation or development of any material Acquired Corporation
Proprietary Asset have executed and delivered to the Acquired Corporations an
agreement that is substantially identical to the form of Confidential
Information and Invention Assignment Agreement previously delivered by the
Company to Parent, and (ii) all current and former consultants and independent
contractors to the Acquired Corporations who are or were involved in, or who
have contributed to, the creation or development of any material Acquired
Corporation Proprietary Asset have executed and delivered to the Company an
agreement that is substantially identical to the form of Consultant Confidential
Information and Invention Assignment Agreement previously delivered to Parent.
No current or former employee, officer, director, stockholder, consultant or
independent contractor has any right, claim or interest in or with respect to
any Acquired Corporation Proprietary Asset.

                (c) To the Knowledge of the Company: (i) all patents,
trademarks, service marks and copyrights held by any of the Acquired
Corporations are valid, enforceable and subsisting; (ii) none of the Acquired
Corporation Proprietary Assets and no Proprietary Asset that has been
substantially developed by any of the Acquired Corporations (either by itself or
with any other Person) infringes, misappropriates or conflicts with any
Proprietary Asset owned or used by any other Person; (iii) none of the products
that are or have been designed, created, substantially developed, assembled,
manufactured or sold by any of the Acquired Corporations is infringing,
misappropriating or making any unlawful or unauthorized use of any Proprietary
Asset owned or used by any other Person, and none of such products has at any
time infringed, misappropriated or made any unlawful or unauthorized use of, and
none of the Acquired Corporations has received any notice or other communication
(in writing or otherwise) of any actual, alleged, possible or potential
infringement, misappropriation or unlawful or unauthorized use of, any
Proprietary Asset owned or used by any other Person; (iv) no other Person is
infringing, misappropriating or making any unlawful or unauthorized use of, and
no Proprietary Asset owned or used by any other Person infringes or conflicts
with, any material Acquired Corporation Proprietary Asset.

                (d) The Acquired Corporation Proprietary Assets constitute all
the Proprietary Assets necessary to enable the Acquired Corporations to conduct
their business in the manner in which such business has been and is being
conducted. None of the Acquired Corporations has (i) licensed any of the
material Acquired Corporation Proprietary Assets to any Person on an exclusive
basis, or (ii) entered into any covenant not to compete or Contract limiting its
ability to exploit fully any material Acquired Corporation Proprietary Assets or
to transact business in any market or geographical area or with any Person.

                (e) Except as set forth in Part 2.9(e)(i) of the Company
Disclosure Schedule, none of the Acquired Corporations has disclosed or
delivered to any Person, or permitted the disclosure or delivery to any escrow
agent or other Person, of any Acquired Corporation Source Code. No event has
occurred, and no circumstance or condition exists, that (with or without notice
or lapse of time) will, or could reasonably be expected to, result in the
disclosure or delivery to any Person of any Acquired Corporation Source Code.
There is no contract pursuant to which the Company has deposited or is required
to deposit with an escrowholder or any other Person any Acquired Corporation
Source Code, and the execution of this Agreement or the consummation of any of
the transactions contemplated hereby will not result in the release or
disclosure of any Acquired Corporation Source Code.

                (f) Except with respect to demonstration or trial copies, no
product, system, program or software module (i) designed or developed or (ii) to
the Knowledge of Company, sold, licensed or otherwise made available by any of
the Acquired Corporations to any Person contains any "back door," "time bomb,"
"Trojan horse," "worm," "drop dead device," "virus" or other software routines
or hardware components designed to permit unauthorized access or to disable or
erase software, hardware or data without the consent of the user.

within the meaning of Section 414(m) of the Code. None of the Acquired
Corporations has ever made a complete or partial withdrawal from a multiemployer
plan, as such term is defined in Section 3(37) of ERISA, resulting in
"withdrawal liability," as such term is defined in Section 4201 of ERISA
(without regard to any subsequent reduction or waiver of such liability under
either Section 4207 or 4208 of ERISA).

                (f) None of the Acquired Corporations has any plan or commitment
to create any Plan or to modify or change any existing Plan (other than to
comply with applicable law) in a manner that would affect any current or former
employee or director of any of the Acquired Corporations.

                (g) No Plan provides death, medical or health benefits (whether
or not insured) with respect to any current or former employee or director of
any of the Acquired Corporations after termination of service of such employee
or director (other than (i) benefit coverage mandated by applicable law,
including coverage provided pursuant to Section 4980B of the Code, (ii) deferred
compensation benefits accrued as liabilities on the Unaudited Interim Balance
Sheet, and (iii) benefits the full cost of which are borne by current or former
employees or directors of any of the Acquired Corporations (or their
beneficiaries)).

                (h) With respect to any Plan constituting a group health plan
within the meaning of Section 4980B(g)(2) of the Code, to the Knowledge of the
Company, the provisions of Section 4980B of the Code ("COBRA") have been
complied with in all material respects.

                (i) To the Knowledge of the Company, each of the Plans has been
operated and administered in all material respects in accordance with applicable
Legal Requirements, including without limitation ERISA and the Code, each Legal
Requirement pursuant to which any of the Acquired


                                      18.
   25

Corporations is required to establish any reserve or make any contribution for
the benefit of any current or former employee located in the United States,
United Kingdom, France, Germany or any other foreign jurisdiction.

                (j) Each of the Plans intended to be qualified under Section
401(a) of the Code has received a favorable determination letter from the
Internal Revenue Service or the deadline for applying to the Internal Revenue
Service for such a determination letter has yet to expire, and the Company is
not aware of any reason why any such determination letter could be revoked or
should not be issued.

                (k) Except pursuant to the Change of Control Agreements or as
set forth in Part 2.17(k) of the Company Disclosure Schedule, neither the
execution, delivery or performance of this Agreement, nor the consummation of
the Merger or any of the other transactions contemplated by this Agreement, will
result in any bonus, golden parachute, severance or other payment or obligation
to any current or former employee or director of any of the Acquired
Corporations (whether or not under any Plan), materially increase the benefits
payable or provided under any Plan, or result in any acceleration of the time of
payment, provision or vesting of any such benefits. Without limiting the
generality of the foregoing (and except pursuant to the Change of Control
Agreements or as set forth in Part 2.17(k) of the Company Disclosure Schedule),
the consummation of the Merger will not result in the acceleration of vesting of
any unvested Company Options.

                (l) Part 2.17(l) of the Company Disclosure Schedule identifies
each employee of each of the Acquired Corporations as of the date of this
Agreement, and correctly reflects, in all material respects, the current salary
and any other compensation payable to such employee (including compensation
payable pursuant to bonus, deferred compensation or commission arrangements),
such employee's employer, years employed and position. None of the Acquired
Corporations is a party to any collective bargaining contract or other Contract
with a labor union involving any of its employees. All of the employees of the
Acquired Corporations are "at will" employees.

                (m) There is no employee of any of the Acquired Corporations who
is not fully available to perform work because of disability or other leave and
sets forth the basis of such disability (to the extent known by the Company) or
leave and the anticipated date of such employee's return to full service.

                (n) To the Knowledge of the Company, each of the Acquired
Corporations is in compliance in all material respects with all applicable Legal
Requirements and Contracts relating to employment, employment practices, wages,
bonuses and terms and conditions of employment, including employee compensation
matters.

                (o) Each of the Acquired Corporations has good labor relations,
and the Company has no Knowledge of any facts indicating that (i) the
consummation of the Merger or any of the other transactions contemplated by this
Agreement will have a material adverse effect on the labor relations of any of
the Acquired Corporations, or (ii) any of the employees of any of the Acquired
Corporations intends to terminate his or her employment with such Acquired
Corporation.

            2.18 ENVIRONMENTAL MATTERS. Each of the Acquired Corporations is in
compliance in all material respects with all applicable Environmental Laws,
which compliance includes the possession by each of the Acquired Corporations of
all permits and other Governmental Authorizations required of them under
applicable Environmental Laws, and compliance in all material respects with the
terms and conditions thereof. To the Knowledge of the Company, since June 30,
1999, none of the Acquired Corporations has received any notice or other
communication (in writing or otherwise), whether from a


                                      19.
   26

Governmental Body, citizens group, employee or otherwise, that alleges that any
of the Acquired Corporations is not in compliance in all material respects with
any Environmental Law. To the Knowledge of the Company, no current or prior
owner of any property leased by any of the Acquired Corporations has received
any notice or other communication (in writing or otherwise), whether from a
Government Body, citizens group, employee or otherwise, that alleges that such
current or prior owner or any of the Acquired Corporations is not in compliance
in all material respects with any Environmental Law. To the Knowledge of the
Company (a) all property that is leased to or used by the Acquired Corporations,
and all surface water, groundwater and soil associated with such property is
free of any material environmental contamination of any nature, (b) none of the
property leased to or used by any of the Acquired Corporations presently
contains any underground storage tanks, asbestos, equipment using PCBs or
underground injection wells, and (c) none of the property leased to or used by
any of the Acquired Corporations presently contains any septic tanks in which
process wastewater or any Materials of Environmental Concern have been disposed.
To the Knowledge of the Company, no Acquired Corporation has sent or
transported, or arranged to send or transport, any Materials of Environmental
Concern to a site that, pursuant to any applicable Environmental Law (i) has
been placed on the "National Priorities List" of hazardous waste sites or any
similar state list, (ii) is otherwise designated or identified as a potential
site for remediation, cleanup, closure or other environmental remedial activity,
or (iii) is subject to a Legal Requirement to take "removal" or "remedial'
action as detailed in any applicable Environmental Law or to make payment for
the cost of cleaning up the site. (For purposes of this Section 2.18: (A)
"ENVIRONMENTAL LAW" means any federal, state, local or foreign Legal Requirement
relating to pollution or protection of human health from Materials of
Environmental Concern or protection of the environment (including ambient air,
surface water, ground water, land surface or subsurface strata), including any
law or regulation relating to emissions, discharges, releases or threatened
releases of Materials of Environmental Concern, or otherwise relating to the
manufacture, processing, distribution, use, treatment, storage, disposal,
transport or handling of Materials of Environmental Concern; and (B) "MATERIALS
OF ENVIRONMENTAL CONCERN" means chemicals, pollutants, contaminants, wastes,
toxic substances, petroleum and petroleum products and any other substance that
is regulated by any Governmental Body with respect to the environment.)

            2.19 INSURANCE. The Company has delivered to Parent certificates of
insurance and summaries of all material insurance policies and all material self
insurance programs and arrangements relating to the business, assets and
operations of the Acquired Corporations. Each of such insurance policies is in
full force and effect. Since June 30, 1999, none of the Acquired Corporations
has received any notice or other communication regarding any actual or possible
(a) cancellation or invalidation of any insurance policy, (b) refusal of any
coverage or rejection of any material claim under any insurance policy, or (c)
material adjustment in the amount of the premiums payable with respect to any
insurance policy. There is no pending workers' compensation or other claim under
or based upon any insurance policy of any of the Acquired Corporations.

            2.20 TRANSACTIONS WITH AFFILIATES. Except as set forth in the
Company SEC Reports, since the date of the Company's last proxy statement filed
with the SEC, no event has occurred that would be required to be reported by the
Company pursuant to Item 404 of Regulation S-K promulgated by the SEC. Part 2.20
of the Company Disclosure Schedule identifies each person who is (or who may be
deemed to be) an "affiliate" (as that term is used in Rule 145 under the
Securities Act) of the Company as of the date of this Agreement.

            2.21 LEGAL PROCEEDINGS; ORDERS.

                (a) There is no pending Legal Proceeding, and (to the Knowledge
of the Company) no Person has threatened to commence any Legal Proceeding: (i)
that involves any of the Acquired Corporations or any of the assets owned or
used by any of the Acquired Corporations and that, if adversely determined,
would reasonably be expected to have a Material Adverse Effect on the Acquired
Corporations; or (ii) that challenges, or that may have the effect of
preventing, delaying, making illegal or otherwise interfering with, the Merger
or any of the other transactions contemplated by this Agreement. To the
Knowledge of the Company, no event has occurred, and no claim, dispute or other
condition or circumstance exists, that would reasonably be expected to, give
rise to or serve as a basis for the commencement of any such Legal Proceeding.

                (b) There is no material order, writ, injunction, judgment or
decree to which any of the Acquired Corporations, or any of the assets owned or
used by any of the Acquired Corporations, is subject. To the Knowledge of the
Company, no officer or key employee of any of the Acquired Corporations is
subject to any order, writ, injunction, judgment or decree that prohibits such
officer or other key employee from engaging in or continuing any conduct,
activity or practice relating to the business of any of the Acquired
Corporations.

            2.22 AUTHORITY; INAPPLICABILITY OF ANTI-TAKEOVER STATUTES; BINDING
NATURE OF AGREEMENT. The Company has the absolute and unrestricted right, power
and authority to enter into and to perform its obligations under this Agreement.
The board of directors of the Company (at a meeting duly called and held on June
7, 2000) has (a) determined (pursuant to a unanimous vote of all members of the
board of directors of the Company) that the Merger is advisable and fair and in
the best interests of the Company and its stockholders, (b) authorized and
approved (pursuant to a unanimous vote of all members of the board of directors
of the Company) the execution, delivery and performance of this Agreement by the
Company and approved (pursuant to a unanimous vote of all members of the board
of directors of the Company) the Merger, (c) recommended (pursuant to a
unanimous vote of all members of the board of directors of the Company) the
approval of this Agreement and the Merger by the holders of Company Common Stock
and directed that this Agreement and the Merger be submitted for consideration

in Section 5.2), and (d) adopted (pursuant to a unanimous vote of all members of
the board of directors of the Company) a resolution having the effect of causing
the Company not to be subject to any state takeover law or similar Legal
Requirement that might otherwise apply to the Merger or any of the other
transactions contemplated by this Agreement. This Agreement constitutes the
legal, valid and binding obligation of the Company, enforceable against the
Company in accordance with its terms, subject to (i) laws of general application
relating to bankruptcy, insolvency and the relief of debtors, and (ii) rules of
law governing specific performance, injunctive relief and other equitable
remedies.

            2.23 SECTION 203 OF THE DGCL NOT APPLICABLE. As of the date hereof
and at all times on or prior to the Effective Time, the restrictions applicable
to business combinations contained in Section 203 of the DGCL are, and will be,
inapplicable to the execution, delivery and performance of this Agreement and to
the consummation of the Merger and the other transactions contemplated by this
Agreement. Prior to the execution of those certain Voting Agreements of even

the Company Disclosure Schedule, the Board of Directors of the Company approved
said Voting Agreements and the transactions contemplated thereby.

            2.24 RESERVED.

            2.26 ACCOUNTING MATTERS. To the Knowledge of the Company, neither
any of the Acquired Corporations nor any affiliate (as that term is used in Rule
145 under the Securities Act) of any of the Acquired Corporations has taken or
agreed to take, or plans to take, any action that could prevent Parent from
accounting for the Merger as a "pooling of interests" in accordance with
generally accepted accounting principles, Accounting Principles Board Opinion
No. 16 and all published rules, regulations and policies of the SEC. The Company
has received oral advice from PricewaterhouseCoopers LLP regarding
PricewaterhouseCoopers LLP's concurrence with the Company's management's
conclusion (subject to the qualifications contained in such oral advice) that
the Company is a "poolable entity" in accordance with generally accepted
accounting principles, Accounting Principles Board Opinion No. 16 and all
published rules, regulations and policies of the SEC, such advice being based on
facts and circumstances known to the Company and PricewaterhouseCoopers LLP as
of the date of this Agreement.

            2.27 VOTE REQUIRED. The affirmative vote of the holders of a
majority of the shares of Company Common Stock outstanding on the record date
for the Company Stockholders' Meeting (the "REQUIRED COMPANY STOCKHOLDER VOTE")
is the only vote of the holders of any class or series of the Company's capital
stock necessary to approve this Agreement, the Merger and the other transactions
contemplated by this Agreement.

            2.28 NON-CONTRAVENTION; CONSENTS. Except as would not result in a
Material Adverse Effect on the Acquired Corporations, neither (1) the execution,
delivery or performance of this Agreement by the Company, nor (2) the
consummation of the Merger or any of the other transactions contemplated by this
Agreement by the Company, will (with or without notice or lapse of time):

               (a) contravene, conflict with or result in a violation of (i) any
        of the provisions of the certificate of incorporation, bylaws or other
        charter or organizational documents of any of the Acquired Corporations,
        or (ii) any resolution adopted by the stockholders, the board of
        directors or any committee of the board of directors of any of the
        Acquired Corporations;

               (b) contravene, conflict with or result in a violation of any
        Legal Requirement, or give any Governmental Body or other Person the
        right to challenge the Merger or any of the other transactions
        contemplated by this Agreement or to exercise any remedy or obtain any
        relief under any order, writ, injunction, judgment or decree to which
        any of the Acquired Corporations, or any of the assets owned or used by
        any of the Acquired Corporations, is subject;

               (c) contravene, conflict with or result in a violation of any of

        revoke, withdraw, suspend, cancel, terminate or modify, any Governmental
        Authorization that is held by any of the Acquired Corporations or that
        otherwise relates to the business of any of the Acquired Corporations or
        to any of the assets owned or used by any of the Acquired Corporations;

               (d) contravene, conflict with or result in a material violation
        or breach of, or result in a material default under, any provision of
        any Material Contract, or give any Person the right to (i) declare a
        default or exercise any remedy under any such Material Contract, (ii)
        accelerate the maturity or performance of any such Material Contract, or
        (iii) cancel, terminate or modify any term of such Material Contract; or

               (e) result in the imposition or creation of any Encumbrance upon
        or with respect to any asset owned or used by any of the Acquired
        Corporations (except for minor liens that will not, in any case or in
        the aggregate, materially detract from the value of the assets subject
        thereto or materially impair the operations of any of the Acquired
        Corporations).

broker, finder or investment banker is entitled to any brokerage, finder's or
other fee or commission in connection with the Merger or any of the other
transactions contemplated by this Agreement based upon arrangements made by or

Parent accurate and complete copies of all agreements under which any such fees,
commissions or other amounts have been paid to and all indemnification and other
agreements related to the engagement of the Company Financial Advisor.

provided) not false or misleading.

                (b) None of the information supplied or to be supplied by or on

Parent) that the Merger and the issuance of Parent Common Stock in the Merger

to Parent's Board of Directors be submitted for consideration by Parent's
stockholders at the Parent Stockholders' Meeting (as defined in Section 5.3).
This Agreement constitutes the legal, valid and binding obligation of Parent and
Merger Sub, enforceable against them in accordance with its terms, subject to
(i) laws of general application relating to bankruptcy, insolvency and the
relief of debtors, and (ii) rules of law governing specific performance,

        contemplated by this Agreement or to exercise any remedy or obtain any
        relief under any order, writ, injunction, judgment or decree to which
        Parent or Merger Sub, or any of the assets owned or used by Parent or
        Merger Sub, is subject;

        with existing bonus plans and (C) make profit sharing or similar
        payments;

                   (xii) hire any employee at the level of vice president or
        above, or with an annual base salary in excess of $100,000;

                   (xiii) change of its pricing policies, product return
        policies, product maintenance polices, service policies, product
        modification or upgrade policies, personnel policies or other business
        policies, or any of its methods of accounting or accounting practices in
        any respect;

                   (xiv) take or permit to be taken any action that could
        preclude Parent from accounting for the merger as a "pooling of
        interests" for accounting purposes;

                   (xv) make any Tax election inconsistent with past practices;

                   (xvi) initiate any material Legal Proceeding or settle any
        Legal Proceeding involving payments by any of the Acquired Corporations
        in excess of $100,000 or equitable relief against any of the Acquired
        Corporations;

                   (xvii) enter into any material transaction or take any other
        material action outside the ordinary course of business or inconsistent
        with past practices; or

                   (xviii) agree or commit to take any of the actions described
        in the foregoing subsections of this Section 4.2(b).

Without limiting any other provision of this Section 4.2(b), during the
Pre-Closing Period, the Company agrees to consult with Parent a reasonable
period of time prior to: (A) permitting any of the Acquired Corporations to
enter into any Contract of the type referred to in Section 2.10(a)(iii), and (B)
hiring any employee who would not be subject to the provision of Section
4.2(b)(xii) (it being understood that the actions referred to in this sentence
shall not require the prior written consent of Parent).

                (c) During the Pre-Closing Period, the Company shall promptly
notify Parent in writing of: (i) the discovery by the Company of any event,
condition, fact or circumstance that occurred or existed on or prior to the date
of this Agreement and that caused or constitutes a material inaccuracy in


                                      33.
   40

any representation or warranty made by the Company in this Agreement; (ii) any
event, condition, fact or circumstance that occurs, arises or exists after the
date of this Agreement and that would cause or constitute a material inaccuracy
in any representation or warranty made by the Company in this Agreement if (A)
such representation or warranty had been made as of the time of the occurrence,
existence or discovery of such event, condition, fact or circumstance, or (B)
such event, condition, fact or circumstance had occurred, arisen or existed on
or prior to the date of this Agreement; (iii) any material breach of any
covenant or obligation of the Company; and (iv) any event, condition, fact or
circumstance that would make the timely satisfaction of any of the conditions
set forth in Section 6 or Section 7 impossible or unlikely or that has had or
could reasonably be expected to have a Material Adverse Effect on the Acquired
Corporations. Without limiting the generality of the foregoing, the Company
shall promptly advise Parent in writing of any Legal Proceeding or material
claim threatened, commenced or asserted against or with respect to any of the
Acquired Corporations. No notification given to Parent pursuant to this Section
4.2(c) shall limit or otherwise affect any of the representations, warranties,
covenants or obligations of the Company contained in this Agreement.

                (d) If any event, condition, fact or circumstance that is
required to be disclosed pursuant to Section 4.2(c) requires any change in the
Disclosure Schedule, or if any such event, condition, fact or circumstance would
require such a change assuming the Disclosure Schedule were dated as of the date
of the occurrence, existence or discovery of such event, condition, fact or
circumstance, then the Company shall promptly deliver to Parent an update to the
Disclosure Schedule specifying such change. No such update shall be deemed to
supplement or amend the Disclosure Schedule for the purpose of (i) determining
the accuracy of any of the representations and warranties made by the Company or
any of the Designated Shareholders in this Agreement, or (ii) determining
whether any of the conditions set forth in Section 6 has been satisfied.

            4.3 NO SOLICITATION.

                (a) The Company shall not directly or indirectly, and shall not
authorize or permit any of the other Acquired Corporations or any Representative
of any of the Acquired Corporations directly or indirectly to, (i) solicit,
initiate, encourage or induce the making, submission or announcement of any
Acquisition Proposal or take any action that could reasonably be expected to
lead to an Acquisition Proposal, (ii) furnish any information regarding any of
the Acquired Corporations to any Person in connection with or in response to an
Acquisition Proposal, (iii) engage in discussions or negotiations with any
Person with respect to any Acquisition Proposal, (iv) approve, endorse or
recommend any Acquisition Proposal or (v) enter into any letter of intent or
similar document or any Contract contemplating or otherwise relating to any
Acquisition Transaction; provided, however, that prior to the adoption and
approval of this Agreement by the Required Company Stockholder Vote, the Company
shall not be prohibited by this Section 4.3(a) from furnishing nonpublic
information regarding the Acquired Corporations to, or entering into discussions
with, any Person in response to a Superior Offer that is submitted by such
Person (and not withdrawn) if (1) neither the Company nor any Representative of
any of the Acquired Corporations shall have violated any of the restrictions set
forth in this Section 4.3, (2) the board of directors of the Company concludes
in good faith, after consultation with its outside legal counsel, that the
failure to take such action would be inconsistent with the fiduciary obligations
of such board of directors to the Company's stockholders under applicable law,
(3) prior to furnishing any such nonpublic information to, or entering into
discussions with, such Person, the Company gives Parent written notice of the
identity of such Person and of the Company's intention to furnish nonpublic
information to, or enter into discussions with, such Person, and the Company
receives from such Person an executed confidentiality agreement containing
customary limitations on the use and disclosure of all nonpublic written and
oral information furnished to such Person by or on behalf of the Company, and
(4) prior to furnishing any such nonpublic information to such Person, the
Company furnishes such nonpublic information to Parent (to the extent such
nonpublic information has not been previously furnished by the


                                      34.
   41

Company to Parent); and provided, further, that nothing herein shall prevent the
Board of Directors of the Company from taking, and disclosing to the Company's
stockholders, a position contemplated by Rules 14d-9 and 14e-2 promulgated under
the Exchange Act. The parties agree that for purposes of the preceding sentence
(but for no other purpose), an offer which is conditioned on completion of due
diligence and other customary conditions (and regarding which the board of
directors of the Company determines, in good faith, based on the advice of its
financial advisor, that financing is likely to be obtained) shall be deemed to
constitute a "Superior Offer" if such offer otherwise meets the definition of
"Superior Offer" set forth in Exhibit A (other than the financing portion of
such definition). Without limiting the generality of the foregoing, the Company
acknowledges and agrees that any violation of any of the restrictions set forth
in the preceding sentence by any Representative of any of the Acquired
Corporations, whether or not such Representative is purporting to act on behalf
of any of the Acquired Corporations, shall be deemed to constitute a breach of
this Section 4.3 by the Company. The Company shall promptly notify Parent in
writing of any material inquiry, proposal or offer relating to a possible
Acquisition Transaction that is received by the Company during the Pre-Closing
Period.

                (b) The Company shall promptly advise Parent orally and in
writing of any Acquisition Proposal (including the identity of the Person making
or submitting such Acquisition Proposal and the terms thereof) that is made or
submitted by any Person during the Pre-Closing Period. The Company shall keep
Parent fully informed with respect to the status of any such Acquisition
Proposal and any modification or proposed modification thereto.

            4.4 OPERATION OF PARENT'S BUSINESS.

                (a) During the Pre-Closing Period: (i) Parent shall ensure that
it conducts its business and operations (A) in the ordinary course and in
accordance with past practices and (B) in substantial compliance with all
applicable Legal Requirements and the material requirements of all material
contracts; and (ii) Parent shall use commercially reasonable efforts to ensure
that it preserves intact its current business organization, keeps available the
services of its current officers and other employees and maintains its relations
and goodwill with all suppliers, customers, landlords, creditors, licensors,
licensees, employees and other Persons having business relationships with
Parent. By way of amplification and without limitation, neither Parent nor any
of its subsidiaries shall, between the date hereof and the Effective Time,
directly or indirectly do, or propose to do, any of the following without the
prior written consent of Company:

                    (i) amend or otherwise change the Certificate of
Incorporation or Bylaws or equivalent organizational document of Parent or any
of its subsidiaries or alter through merger, liquidation, reorganization,
restructuring or in any other fashion the corporate structure of Parent;

                    (ii) amend the terms of, repurchase, redeem or otherwise
acquire, or permit any Subsidiary to repurchase, redeem or otherwise acquire,
any of its securities or any securities of its Subsidiaries; or propose to do
any of the foregoing;

                    (iii) (x) acquire or agree to acquire by merging or
consolidating with, or by purchasing any equity interest in or a portion of the
assets of, or by any other manner, any business or any corporation, partnership,
association or other business organization or division thereof, or (y) otherwise
acquire or agree to acquire any assets which are material, individually or in
the aggregate, to the business of Parent or enter into any joint ventures,
strategic partnerships or alliances, in the case of both (x) and (y), where such
acquisition or agreement is reasonably likely to materially delay consummation
of the Merger or materially adversely affect Parent's ability to consummate the
Merger;


                                      35.
   42

                    (iv) adopt a plan of complete or partial liquidation or
dissolution of Parent;

                    (v) fail to make in a timely manner any material filings
with the SEC required under the Securities Act or the Exchange Act or the rules
or regulations promulgated thereunder; or

                    (vi) agree in writing or otherwise to take any of the
actions described in Section 4.4(a)(i) through (v) above.

                (b) During the Pre-Closing Period, Parent shall promptly notify
the Company in writing of: (i) the discovery by Parent of any event, condition,
fact or circumstance that occurred or existed on or prior to the date of this
Agreement and that caused or constitutes a material inaccuracy in any
representation or warranty made by Parent in this Agreement; (ii) any event,
condition, fact or circumstance that occurs, arises or exists after the date of
this Agreement and that would cause or constitute a material inaccuracy in any
representation or warranty made by Parent in this Agreement if (A) such
representation or warranty had been made as of the time of the occurrence,
existence or discovery of such event, condition, fact or circumstance, or (B)
such event, condition, fact or circumstance had occurred, arisen or existed on
or prior to the date of this Agreement; (iii) any material breach of any
covenant or obligation of Parent; and (iv) any event, condition, fact or
circumstance that would make the timely satisfaction of any of the conditions
set forth in Section 6 or Section 7 impossible or unlikely or that has had or
could reasonably be expected to have a Material Adverse Effect on Parent.
Without limiting the generality of the foregoing, Parent shall promptly advise
the Company in writing of any Legal Proceeding or material claim overtly
threatened, commenced or asserted against or with respect to Parent. No
notification given to the Company pursuant to this Section 4.4(b) shall limit or
otherwise affect any of the representations, warranties, covenants or
obligations of Parent contained in this Agreement.

        SECTION 5. ADDITIONAL COVENANTS OF THE PARTIES

            5.1 REGISTRATION STATEMENT; JOINT PROSPECTUS/PROXY STATEMENT.

                (a) As promptly as practicable after the date of this Agreement,
Parent and the Company shall prepare and cause to be filed with the SEC the
Joint Prospectus/Proxy Statement and Parent shall prepare and cause to be filed
with the SEC the Form S-4 Registration Statement, in which the Joint
Prospectus/Proxy Statement will be included as a prospectus. Each of Parent and
the Company shall use commercially reasonable efforts to cause the Form S-4
Registration Statement and the Joint Prospectus/Proxy Statement to comply with
the rules and regulations promulgated by the SEC, to respond promptly to any
comments of the SEC or its staff and to have the Form S-4 Registration Statement
declared effective under the Securities Act as promptly as practicable after it
is filed with the SEC. The Company and Parent will use commercially reasonable
efforts to cause the Joint Prospectus/Proxy Statement to be mailed to their
respective stockholders as promptly as practicable after the Form S-4
Registration Statement is declared effective under the Securities Act. Parent
and the Company shall promptly furnish to the other information concerning
Parent or the Company or their respective stockholders that may be required or
reasonably requested in connection with any action contemplated by this Section
5.1. If any event relating to any of the Acquired Corporations or Parent occurs,
or if either party becomes aware of any information that should be disclosed in
an amendment or supplement to the Form S-4 Registration Statement or the Joint
Prospectus/Proxy Statement, then such party shall promptly inform the other
party thereof and shall cooperate in filing such amendment or supplement with
the SEC and, if appropriate, in mailing such amendment or supplement to the
stockholders of the Company or Parent.


                                      36.
   43

                (b) Prior to the Effective Time, Parent shall use commercially
reasonable efforts to obtain all regulatory approvals needed to ensure that the
Parent Common Stock to be issued in the Merger will be registered or qualified
under the securities law of every jurisdiction of the United States in which any
registered holder of Company Common Stock has an address of record on the record
date for determining the stockholders entitled to notice of and to vote at the
Company Stockholders' Meeting; provided, however, that Parent shall not be
required (i) to qualify to do business as a foreign corporation in any
jurisdiction in which it is not now qualified or (ii) to file a general consent
to service of process in any jurisdiction.

            5.2 COMPANY STOCKHOLDERS' MEETING.

                (a) The Company shall take all action necessary under all
applicable Legal Requirements to call, give notice of, convene and hold a
meeting of the holders of their Common Stock to consider, act upon and vote upon
the adoption and approval of this Agreement and the approval of the Merger (the
"COMPANY STOCKHOLDERS' MEETING"). The Company Stockholders' Meeting will be held
as promptly as practicable after the Form S-4 Registration Statement is declared
effective under the Securities Act; provided, however, that notwithstanding
anything to the contrary contained in this Agreement, the Company may adjourn or
postpone the Company Stockholder's Meeting to the extent necessary to ensure
that any necessary supplement or amendment to the Joint Proxy
Statement/Prospectus is provided to the Company's stockholders in advance of a
vote on the Merger Agreement and the Merger or, if as of the time for which the
Company Stockholders' Meeting is originally scheduled (as set forth in the Joint
Proxy Statement/Prospectus) there are insufficient shares of Company Common
Stock represented (either in person or by proxy) to constitute a quorum
necessary to conduct the business of the Company Stockholders' Meeting. The
Company and Parent shall cooperate in attempting to cause the Company
Stockholders' Meeting to be scheduled and convened on the same date as the
Parent Stockholders' Meeting (as defined in Section 5.3 below) shall be
scheduled and convened. The Company shall ensure that the Company Stockholders'
Meeting is called, noticed, convened, held and conducted, and that all proxies
solicited in connection with such Company Stockholders' Meeting are solicited,
in compliance with all applicable Legal Requirements. The Company's obligation
to call, give notice of, convene and hold its respective Stockholders' Meeting
in accordance with this Section 5.2(a) shall not be limited or otherwise
affected by the commencement, disclosure, announcement or submission of any
Superior Offer or other Acquisition Proposal, or by any withdrawal, amendment or
modification of the recommendation of the board of directors of either Company
with respect to the Merger.

                (b) Subject to Section 5.2(c): (i) the board of directors of the
Company shall unanimously recommend that the Company's stockholders vote in
favor of and adopt and approve this Agreement and approve the Merger at the
Company Stockholders' Meeting; (ii) the Joint Prospectus/Proxy Statement shall
include a statement to the effect that the board of directors of the Company has
unanimously recommended that the Company's stockholders vote in favor of and
adopt and approve this Agreement and approve the Merger at the Company
Stockholders' Meeting; and (iii) neither the board of directors of the Company
nor any committee thereof shall withdraw, amend or modify, or propose or resolve
to withdraw, amend or modify, in a manner adverse to Parent, the unanimous
recommendation of the board of directors of the Company that the Company's
stockholders vote in favor of and adopt and approve this Agreement and approve
the Merger. For purposes of this Agreement, said recommendation of the board of
directors of the Company shall be deemed to have been modified in a manner
adverse to Parent if said recommendation shall no longer be unanimous.

                (c) Nothing in Section 5.2(b) shall prevent the board of
directors of the Company from withdrawing, amending or modifying its unanimous
recommendation in favor of the Merger at any time prior to the adoption and
approval of this Agreement by the Required Company Stockholder Vote if (i) a
Superior Offer is made to the Company and is not withdrawn, (ii) neither the


                                      37.
   44

Company nor any of its Representatives shall have violated any of the
restrictions set forth in Section 4.3, (iii) the board of directors of the
Company concludes in good faith, after consultation with its outside counsel,
that, in light of such Superior Offer, it would be inconsistent with the
fiduciary obligations of the board of directors of the Company to the Company's
stockholders under applicable law not to withdraw, amend or modify such
recommendation, (iv) the Company provides Parent with at least 24 hours prior
notice of any meeting of the Company's board of directors at which such board of
directors is expected to consider such Superior Offer, and (v) the Company's
board of directors does not withdraw, amend or modify its unanimous
recommendation in favor of the Merger for at least 48 hours after the Company
provides Parent with the name of the Person making such Superior Offer and a
copy of such Superior Offer. Nothing contained in this Section 5.2 shall limit
the Company's obligation to call, give notice of, convene and hold the Company
Stockholders' Meeting (regardless of whether the unanimous recommendation of the
board of directors of the Company shall have been withdrawn, amended or
modified).

            5.3 PARENT STOCKHOLDERS' MEETING.

                (a) Parent shall take all action necessary to call, give notice
of, convene and hold a meeting of the holders of Parent Common Stock to consider
and vote upon the issuance of Parent Common Stock in the Merger and, to the
extent required under Parent's certificate of incorporation and bylaws and
applicable law, the election of Lev J. Leytes to Parent's Board of Directors
(the "PARENT STOCKHOLDERS' MEETING"). The Parent Stockholders' Meeting will be
held as promptly as practicable after the S-4 Registration Statement is declared
effective under the Securities Act; provided, however, that notwithstanding
anything to the contrary contained in this Agreement, Parent may adjourn or
postpone the Parent Stockholders' Meeting to the extent necessary to ensure that
any necessary supplement or amendment to the Joint Proxy Statement/Prospectus is
provided to Parent's stockholders in advance of a vote on the issuance of Parent
Common Stock in the Merger or, if as of the time for which the Parent
Stockholders' Meeting is originally scheduled (as set forth in the Joint Proxy
Statement/Prospectus) there are insufficient shares of Parent Common Stock
represented (either in person or by proxy) to constitute a quorum necessary to
conduct the business of the Parent's Stockholders' Meeting. Parent shall ensure
that the Parent Stockholders' Meeting is called, noticed, convened, held and
conducted, and that all proxies solicited in connection with such Parent
Stockholders' Meeting are solicited, in compliance with all applicable Legal
Requirements.

                (b) (i) The board of directors of Parent shall unanimously
recommend that Parent's stockholders vote in favor of the issuance of Parent
Common Stock in the Merger and the election of Lev J. Leytes to Parent's Board
of Directors at the Parent Stockholders' Meeting; (ii) the Joint
Prospectus/Proxy Statement shall include a statement to the effect that the
board of directors of Parent has unanimously recommended that Parent's
stockholders vote in favor of the issuance of shares of Parent Common Stock in
the Merger and the election of Lev. J. Leytes to Parent's Board of Directors at
Parent's Stockholders' Meeting; and (iii) neither the board of directors of
Parent nor any committee thereof shall withdraw, amend or modify, or propose or
resolve to withdraw, amend or modify, in a manner adverse the Company, the
unanimous recommendation of the board of directors of Parent that Parent's
stockholders vote in favor of the issuance of Parent Common Stock in the Merger
and the election of Lev J. Leytes to Parent's Board of Directors. For purposes
of this Agreement, said recommendation of the board of directors of Parent shall
be deemed to have been modified in a manner adverse to the Company if said
recommendation shall no longer be unanimous.

            5.4 REGULATORY APPROVALS. Each party shall use commercially
reasonable efforts to file, as promptly as practicable after the date of this
Agreement, all notices, reports and other documents required to be filed by such
party with any Governmental Body with respect to the Merger and the other
transactions contemplated by this Agreement, and to submit promptly any
additional information


                                      38.
   45

requested by any such Governmental Body. Without limiting the generality of the
foregoing, the Company and Parent shall, promptly after the date of this
Agreement, prepare and file the notifications required under the HSR Act, if
any, in connection with the Merger. The Company and Parent shall respond as
promptly as practicable to (i) any inquiries or requests received from the
Federal Trade Commission or the Department of Justice for additional information
or documentation and (ii) any inquiries or requests received from any state
attorney general or other Governmental Body in connection with antitrust or
related matters. Each of the Company and Parent shall (1) give the other party
prompt notice of the commencement of any Legal Proceeding by or before any
Governmental Body with respect to the Merger or any of the other transactions
contemplated by this Agreement, (2) keep the other party informed as to the
status of any such Legal Proceeding, and (3) promptly inform the other party of
any communication to or from the Federal Trade Commission, the Department of
Justice or any other Governmental Body regarding the Merger. The Company and
Parent will consult and cooperate with one another, and will consider in good
faith the views of one another, in connection with any analysis, appearance,
presentation, memorandum, brief, argument, opinion or proposal made or submitted
in connection with any Legal Proceeding under or relating to the HSR Act or any
other federal or state antitrust or fair trade law. In addition, except as may
be prohibited by any Governmental Body or by any Legal Requirement, in
connection with any Legal Proceeding under or relating to the HSR Act or any
other federal or state antitrust or fair trade law or any other similar Legal
Proceeding, each of the Company and Parent will permit authorized
Representatives of the other party to be present at each meeting or conference
relating to any such Legal Proceeding and to have access to and be consulted in
connection with any document, opinion or proposal made or submitted to any
Governmental Body in connection with any such Legal Proceeding.

            5.5 STOCK OPTIONS AND WARRANTS.

                (a) Subject to Section 5.5(b), at the Effective Time, all rights
with respect to Company Common Stock under each Company Option then outstanding
shall be converted into and become rights with respect to Parent Common Stock,
and Parent shall assume each such Company Option in accordance with the terms
(as in effect as of the date of this Agreement) of the stock option plan under
which it was issued, the stock option agreement by which it is evidenced and any
applicable Change of Control Agreement. At the Effective Time, all rights with
respect to Company Common Stock under each Company Warrant then outstanding
shall be converted into and become rights to Parent Common Stock, and Parent
shall assume each such Company Warrant in accordance with the terms (as in
effect as of the date of this Agreement) of the Company Warrant and any warrant
agreement by which it is evidenced. From and after the Effective Time, (i) each
Company Option and Company Warrant assumed by Parent may be exercised solely for
shares of Parent Common Stock, (ii) the number of shares of Parent Common Stock
subject to each such Company Option and Company Warrant shall be equal to the
number of shares of Company Common Stock subject to such Company Option and
Company Warrant immediately prior to the Effective Time multiplied by the
Exchange Ratio, rounding down to the nearest whole share, (iii) the per share
exercise price under each such Company Option and Company Warrant shall be
adjusted by dividing the per share exercise price under such Company Option and
Company Warrant by the Exchange Ratio and rounding up to the nearest cent and
(iv) any restriction on the exercise of any such Company Option and Company
Warrant shall continue in full force and effect and the term, exercisability,
vesting schedule and other provisions of such Company Option and Company Warrant
shall otherwise remain unchanged; provided, however, that each Company Option
and Company Warrant assumed by Parent in accordance with this Section 5.5(a)
shall, in accordance with its terms, be subject to further adjustment as
appropriate to reflect any stock split, division or subdivision of shares, stock
dividend, reverse stock split, consolidation of shares, reclassification,
recapitalization or other similar transaction subsequent to the Effective Time.
It is the intention of the parties that the Company Options assumed by Parent
qualify following the Effective Time as incentive stock options as defined in
Section 422 of the Code to the extent such Company Options qualified as
incentive stock options prior to the


                                      39.
   46

Effective Time. Parent shall file with the SEC, within 7 days after the date on
which the Merger becomes effective, a registration statement on Form S-8
relating to the shares of Parent Common Stock issuable with respect to the
Company Options assumed by Parent in accordance with this Section 5.5(a). Parent
shall use commercially reasonable efforts to maintain the effectiveness of such
registration statement (and maintain the current status of the prospectus
contained in such registration statement) for so long as the Company Options
remain outstanding. As soon as practicable after the Effective Time (but in no
event later than 30 days thereafter), Parent shall deliver to each holder of a
Company Option or Company Warrant an appropriate notice setting forth such
holder's rights with respect to such Company Option or Company Warrant and
indicating that such Company Option or Company Warrant shall continue in effect
on the same terms and conditions as were in effect immediately prior to the
Effective Time (subject to the adjustments required pursuant to Section 5.5(a)).

                (b) Notwithstanding anything to the contrary contained in this
Section 5.5, in lieu of assuming outstanding Company Options in accordance with
Section 5.5(a), Parent may, at its election, cause such outstanding Company
Options to be replaced by issuing reasonably equivalent replacement stock
options in substitution therefor ("REPLACEMENT OPTIONS"). The vesting schedule
of any Replacement Option shall be the same as that of the option being
replaced. The number of shares of Parent Common Stock subject to a Replacement
Option, as well as the per share exercise price of such Replacement Option,
shall be determined in the manner specified in Section 5.5(a). If Parent elects
to substitute Replacement Options in lieu of assuming outstanding Company
Options, Parent shall take all corporate action necessary to approve the
Replacement Options described in this Section 5.5(b) in a manner qualifying
under Section 424(a) of the Code and to grant options that qualify as incentive
stock options under Section 422 of the Code (to the extent such Company Options
qualified as incentive stock options prior to the Effective Time) and shall
deliver an agreement evidencing such Replacement Options to each applicable
holder of a Company Option within 30 days after the Effective Time. Shares of
Parent Common Stock issuable pursuant to the Replacement Options granted
pursuant to this Section 5.5(b) shall be registered on the Form S-8 Registration
Statement referred to in Section 5.5(a). Parent shall use commercially
reasonable efforts to maintain the effectiveness of such registration statement
(and maintain the current status of the prospectus contained in such
registration statement) for so long as the Replacement Options remain
outstanding.

                (c) The Company shall take all action that may be necessary
(under the plans pursuant to which Company Options are outstanding and
otherwise) to effectuate the provisions of this Section 5.5 and to ensure that,
from and after the Effective Time, holders of Company Options have no rights
with respect thereto other than those specifically provided in this Section 5.5.
The parties intend that the assumption or replacement of Company options
provided for under this Section 5.5 shall comply with the provisions of Section
424(a) of the Code, and this Section 5.5 shall be interpreted consistent with
such intent.

                (d) As of the Effective Time, the ESPP shall be terminated. The
rights of participants in the ESPP with respect to any offering period then
underway under the ESPP shall be determined by treating the last business day
prior to the Effective Time as the last day of such offering period and by
making such other pro-rata adjustments as may be required pursuant to the ESPP
to reflect the reduced offering period but otherwise treating such offering
period as a fully effective and completed offering period for all purposes of
such Plan. Prior to the Effective Time, the Company shall take all actions that
are necessary to give effect to the transactions contemplated by this Section
5.5(d); provided, however, that the change in the offering period referred to in
this Section 5.5(d) shall be conditioned upon the consummation of the Merger.

            5.6 EMPLOYEE BENEFITS. Parent agrees that all employees of the
Company who continue employment with Parent or the Company after the Effective
Time shall be eligible to participate in


                                      40.
   47

Parent's health, vacation and other employee benefit plans, to the same extent
as employees of Parent in similar positions and at similar grade levels (it
being understood that such employees shall be eligible to begin to participate
(i) in Parent's employee stock purchase plan upon the commencement of the first
new offering period that commences following the Effective Time, and (ii) in
Parent's other employee benefit plans in accordance with the terms of such
plans; provided, however, that in the case of plans for which the Company
maintains a plan offering the same type of benefit, such eligibility need not be
offered by Parent until the corresponding plan of the Company ceases to be
available after the Effective Time). As soon as administratively feasible
following the Effective Time, Parent agrees to take whatever action is necessary
to transition Company employees into Parent's employee benefits plans as
contemplated by the first sentence of this Section 5.6. Further, until such time
that the continuing Company employees are covered under an employee benefit plan
of Parent, they shall continue to be covered under the corresponding Company
Plan that offers the same type of benefit. Parent also agrees to provide each
such continuing employee with full credit for service as an employee of the
Company or any affiliate thereof prior to the Effective Time for the following
purposes only: for purposes of eligibility, vesting and determination of the
level of benefits (without duplication) under any employee benefit plan or
arrangement maintained by Parent, including Parent's 401(k) plan, and for
Parent's vacation program. To the extent practicable and only if permitted by
the relevant insurance carrier, Parent shall administer its medical plan
("PARENT MEDICAL PLAN") so as to coordinate deductibles, "out-of-pocket"
maximums and maximum benefit restrictions so that: (A) Company employees receive
credit under the Parent Medical Plan toward any deductibles under the Parent
Medical Plan for deductibles paid under any of the medical, dental and
prescription drug plans included within the Company Plans ("Company Medical
Plan") on or prior to the Effective Time which, had the Company employees been
covered by the Parent Medical Plan, would have been taken into account by the
Parent Medical Plan, (B) Company employees receive credit for their eligible
out-of-pocket costs with respect to eligible claims incurred under the Company
Medical Plan which, had the Company employees been covered by the Parent Medical
Plan, would have been taken into account under the Parent Medical Plan toward
any "out-of-pocket" maximums under the Parent Medical Plan, and (C) Company
employees are credited with benefits received under the Company Medical Plan on
or prior to the Effective Time which, had the Company employees been covered by
the Parent Medical Plan, would have been taken into account by the Parent
Medical Plan for purposes of applying the maximum benefit restrictions under the
Parent Medical Plan. Notwithstanding the foregoing, to the extent permitted by
law, Parent reserves the right to enforce, on a nondiscriminatory basis, any
otherwise applicable pre-existing condition limitation under its medical plan
with respect to any Company employee who does not enroll in Parent's medical
plan at the time Parent's medical plan is first made available to such Company
employee.

            5.7 INDEMNIFICATION OF OFFICERS AND DIRECTORS.

                (a) All rights to indemnification existing in favor of those

date of this Agreement) and as provided in the indemnification agreements
between the Company and said Indemnified Persons (as in effect as of the date of
this Agreement), shall survive the Merger and shall be observed by the Surviving
Corporation to the fullest extent available under Delaware law for a period of
five years from the Effective Time.

                (b) From the Effective Time until the fifth anniversary of the

liability insurance maintained by the Company as of the date of this Agreement
(the "EXISTING POLICY"); provided, however, that (i) the Surviving Corporation
may substitute for the Existing Policy a policy or policies of comparable
coverage, and (ii) the Surviving Corporation shall not be required to pay an
annual


                                      41.
   48

premium for the Existing Policy (or for any substitute policies) in excess of
$75,000. In the event any future annual premium for the Existing Policy (or any
substitute policies) exceeds $75,000, the Surviving Corporation shall be
entitled to reduce the amount of coverage of the Existing Policy (or any
substitute policies) to the amount of coverage that can be obtained for a
premium equal to $75,000.

                (c) If the Surviving Corporation does not have sufficient
capital to comply with its obligations under Section 5.6, Parent shall provide
the Surviving Corporation with such capital.

                (d) This Section shall survive the consummation of the Merger,
is intended to benefit the indemnified parties, shall be binding upon all
successors and assigns of the Surviving Corporation and Parent and shall be
enforceable by the indemnified parties.

the Company agrees to cause the Acquired Corporations) (a) not knowingly to take
any action during the Pre-Closing Period that would adversely affect the ability

commercially reasonable efforts to attempt to ensure that none of its
"affiliates" (as that term is used in Rule 145 under the Securities Act) takes
any action that could adversely affect the ability of Parent to account for the

provide to PricewaterhouseCoopers LLP and Ernst & Young LLP such letters as

referred to in Sections 6.6(f) and 6.6(g).

contemplated by this Agreement. Without limiting the generality of the
foregoing, but subject to Section 5.9(b), each party to this Agreement (i) shall

restraint, injunction or other legal bar to the Merger. The Company shall

        consummation of the Merger set forth in Sections 6 and 7 of this
        Agreement would be satisfied with the passage of additional time, then
        in such event the Company shall in its discretion have the right to
        extend the Termination Date to a date not later than February 28, 2001;

               (c) by either Parent or the Company if a court of competent
        jurisdiction or other Governmental Body shall have issued a final and

        action, having the effect of permanently restraining, enjoining or
        otherwise prohibiting the Merger;

               (d) by either Parent or the Company if (i) the Company
        Stockholders' Meeting shall have been held and (ii) this Agreement and

        Company Stockholder Vote; provided, however, that the Company shall not
        be permitted to terminate this Agreement pursuant to this Section 8.1(d)
        unless the Company shall have paid to Parent any fee required to be paid
        to Parent pursuant to Section 8.3(b);

               (e) by Parent (at any time prior to the adoption and approval of
        this Agreement and the Merger by the Required Company Stockholder Vote)
        if a Triggering Event shall have occurred;

               (f) by Parent if any of the Company's representations and
        warranties contained in this Agreement shall have been materially
        inaccurate as of the date of this Agreement or shall

        have become materially inaccurate as of any subsequent date (as if made
        on such subsequent date), or if any of the Company's covenants contained
        in this Agreement shall have been breached in any material respect;
        provided, however, that Parent may not terminate this Agreement under
        this Section 8.1(f): (i) on account of an inaccuracy in the Company's
        representations and warranties that is curable by the Company or on

        inaccuracy or breach; or (ii) if such inaccuracy or breach (considered
        in the aggregate with all other inaccuracies or breaches) would not
        result in a failure of the conditions set forth in Section 6.1 hereof);

               (g) by the Company if any of Parent's representations and
        warranties contained in this Agreement shall have been materially
        inaccurate as of the date of this Agreement or shall have become
        materially inaccurate as of any subsequent date (as if made on such
        subsequent date), or if any of Parent's covenants contained in this
        Agreement shall have been breached in any material respect; provided,
        however, that the Company may not terminate this Agreement under this
        Section 8.1(g): (i) on account of an inaccuracy in Parent's
        representations and warranties that is curable by Parent or on account
        of a breach of a covenant by Parent that is curable by Parent unless
        Parent fails to cure such inaccuracy or breach within 30 days after
        receiving written notice from the Company of such inaccuracy or breach;
        or (ii) if such inaccuracy or breach (considered in the aggregate with
        all other inaccuracies or breaches) would not result in a failure of the
        conditions set forth in Section 7.1 hereof);

               (h) by either Parent or the Company if (i) the Parent
        Stockholders' Meeting shall have been held and (ii) the issuance of
        shares of Parent Common Stock contemplated by this Agreement and the
        Merger shall not have been approved at such meeting by the Required
        Parent Stockholder Vote; provided, however, that Parent shall not be
        permitted to terminate this Agreement pursuant to this Section 8.1(h)
        unless Parent shall have paid to the Company any fee required to be paid
        to the Company pursuant to Section 8.3(b); or

               (i) by the Company if the board of directors of the Company
        shall, subject to complying with the terms of this Agreement, including
        Sections 4.3 and 5.2(c), have approved, endorsed or recommended a
        Superior Offer; provided, however, that the Company shall not be
        permitted to terminate this Agreement pursuant to this Section 8.1(i)
        unless the Company shall have paid to Parent any fee required to be paid
        to Parent pursuant to Section 8.3(b).

            8.2 EFFECT OF TERMINATION. In the event of the termination of this
Agreement as provided in Section 8.1, this Agreement shall be of no further
force or effect (and, except as provided in this Section 8.2, there shall be no
liability or obligation hereunder on the part of any of the parties hereto or
their respective officers, directors, stockholders or Affiliates); provided,
however, that (i) this Section 8.2, Section 8.3 and Section 9 shall survive the
termination of this Agreement and shall remain in full force and effect, and
(ii) the termination of this Agreement shall not relieve any party from any
liability for any willful breach of any representation, warranty or covenant
contained in this Agreement.

2000 that has had, or would reasonably be expected to have, a Material Adverse
Effect on the Acquired Corporations, then, in any such case, Parent shall pay to

6.6(e), 6.6(f), 6.6(g), 6.6(h), 6.6(i) and 6.6(j) (it being the understanding of
the parties that in determining whether the conditions set forth in Section 6.1
and 6.2 shall have been satisfied for this purpose, the term "Termination Date"
shall be substituted for the terms "Closing Date" and "Closing") and (z) the
failure for the condition set forth in Section 6.6(g) to be satisfied is not
directly or indirectly related to any action taken, or failed to be taken, by
the Company or any of its affiliates (except for actions taken prior to the
execution of this Agreement or any fact related to the Company prior to the
execution of this Agreement, in each case the existence of which was disclosed
to Parent and its independent accountants prior to the execution of this
