<PAGE>   8


Effective Time, whether or not vested or exercisable, shall be assumed by Parent
and shall be converted into an option to purchase Parent Common Stock
(collectively, "Substituted Options").

               (ii) Subject to subsection 3.2(d)(iii) below, (A) the number of
shares of Parent Common Stock underlying a Substituted Option shall be equal to
the number of shares of Company Common Stock underlying the subject Company
Option multiplied by the Exchange Ratio and rounded to the nearest whole number,

               (iii) It is the intention of the parties that Company Options
that qualified as incentive stock options, within the meaning of Section 422 of
the Code ("ISOs"), immediately prior to the Effective Time, be converted, when
assumed by Parent, into Substituted Options that qualify as ISOs immediately
following the Effective Time, to the extent permitted by Section 422 of the Code
and applicable terms of the Company Option Plans. In furtherance of such
intention, the formulae, terms and conditions set forth in subsection 3.2(d)(ii)
above may be applied to, or modified for, such Substituted Options as deemed
reasonably necessary by Parent, so long as any such application or modification
does not materially reduce the benefit of the Substituted Option to the holder
thereof.

               (iv) The Company's Employee Stock Purchase Plan (the "Stock
Purchase Plan") shall be terminated prior to the Closing. All funds invested in
the Stock Purchase Plan but not used by employees to purchase stock thereunder
prior to the Effective Time shall be transferred or otherwise credited to

employee shall have purchase rights under Parent's stock purchase plans
substantially similar to those existing under the Stock Purchase Plan

Stock underlying the Substituted Options or shall cause such Parent Common Stock
to be included in an effective Registration Statement on Form S-8 relating to
one or more of Parent's stock option plans (collectively, "Parent Option
Plans"). So long as any Substituted Options remain outstanding, Parent shall use
its reasonable best efforts to maintain the effectiveness of any Registration
Statement(s) related to the Substituted Options (and to maintain the current
status of the prospectus or prospectuses related thereto). At or prior to the
Effective Time, Parent shall take all corporate action necessary to reserve for
issuance a sufficient number of shares of Parent Common Stock for delivery upon
exercise of the Substituted Options. To the extent required by the relevant
market or exchange, Parent shall list or qualify all such shares for trading on
the principal market or exchange on which Parent Common Stock is traded from
time to time.

Parent Common Stock as reported in The Wall Street Journal, Eastern Edition, as

Agent to mail to each holder of record of Company Common Stock (i) a letter of
transmittal, in a typical form and having such provisions as Parent may

holder's shares of Company Common Stock shall pass, only upon delivery of the
Certificates representing such shares to the Exchange Agent, and (ii)
instructions for use in effecting the surrender of such Certificates in exchange
for Merger Certificates and cash in lieu of fractional shares from the Exchange
Fund.

cancellation, together with a duly executed and properly completed Letter of
Transmittal, (i) the holder of the shares of Company Common Stock represented by
such Certificate shall be entitled to receive in exchange therefor from the
Exchange Fund (A) a Merger Certificate representing that number of whole shares
of Parent Common Stock determined by multiplying the number of shares of Company
Common Stock represented by the Certificate by the Exchange Ratio, and (B) a
check representing (1) the amount of cash in lieu of fractional shares of Parent
Common Stock, if any, determined pursuant to paragraph (b) of this Section 3.3,
and (2) any Specified Post-Closing Dividends, in each case less any applicable
tax withholding, and (ii) the Company Common Stock represented by the
surrendered Certificate shall thereupon be canceled.

          (e) In the event of a transfer of ownership of Company Common Stock
which is not registered in the transfer records of the Company, a Merger
Certificate representing the proper number of shares of Parent Common Stock,
together with a check for the cash to be paid in lieu of fractional shares, if
any, may be issued to such transferee of such Company Common Stock, if the
Certificate representing such Company Common Stock is presented to the Exchange
Agent, accompanied by all documents, in form and substance reasonably
satisfactory to Parent and the Exchange Agent, required to evidence and effect
such transfer of Company Common Stock and to evidence that any applicable stock
transfer taxes have been paid. There shall be no


                                       9
<PAGE>   10


transfers on the transfer records of the Company, at or after the Effective
Time, of shares of Company Common Stock which were outstanding immediately prior
to the Effective Time.

          (f) Notwithstanding any other provisions of this Agreement, no
dividends or other distributions declared after the Effective Time on Parent
Common Stock ("Post-Closing Dividends") shall be paid with respect to any shares
of Company Common Stock represented by a Certificate until such Certificate is
surrendered for exchange as provided herein. Subject to the effect of applicable
laws, following surrender of any such Certificate, there shall be paid to the
holder of the certificates representing whole shares of Parent Common Stock
issued in exchange therefor, without interest, (i) at the time of such
surrender, the amount of Post-Closing Dividends with a record date after the
Effective Time theretofore payable with respect to such whole shares of Parent
Common Stock and not paid, less the amount of any withholding taxes which may be
required thereon ("Specified Post-Closing Dividends"), and (ii) at the
appropriate payment date, the amount of Post-Closing Dividends with a record
date after the Effective Time but prior to surrender and a payment date
subsequent to surrender payable with respect to such whole shares of Parent
Common Stock, less the amount of any withholding taxes which may be required
thereon.

          (g) Certificates surrendered for exchange by any Affiliate of the
Company shall not be exchanged until Parent has received a written agreement
from such person as provided in Section 6.8.

          (h) None of Parent, the Company, the Surviving Corporation, the
Exchange Agent or any other person shall be liable to any former stockholder of
the Company for any amount properly delivered to a public official pursuant to
applicable abandoned property, escheat or similar laws.

     3.4 LOST CERTIFICATES. In the event any Certificate shall have been lost,
stolen or destroyed, upon the making and delivery of an affidavit (in form and
substance satisfactory to the Surviving Corporation) of that fact by the person
claiming such Certificate to be lost, stolen or destroyed and, if required by
the Surviving Corporation, the posting by such person of a bond in such
reasonable amount as the Surviving Corporation may direct as indemnity against
any claim that may be made against it with respect to such Certificate, the
Exchange Agent will issue in exchange for such lost, stolen or destroyed
Certificate the shares of Parent Common Stock and cash deliverable in respect
thereof pursuant to this Agreement.

     3.5 ADJUSTMENT OF EXCHANGE RATIO. In the event that, subsequent to the date
of this Agreement but prior to the Effective Time, the outstanding shares of
Parent Common Stock shall have been changed into a different number of shares or
a different class as a result of a stock split, reverse stock split, stock
dividend, subdivision, reclassification, combination, exchange, recapitalization
or other similar transaction, the Exchange Ratio shall be appropriately
adjusted.

material line of products or otherwise to operate its business, (ii) a material
liability of the Company, or (iii) material redesign or other corrective costs
to the Company. The Company has not received, and has no knowledge of, any
charge, complaint, claim, demand or notice alleging any such interference,

Intellectual Property constitutes unfair competition.

          (d) To the knowledge of the Company, no fraud or misrepresentation has
been made by the Company or any of its officers, directors or employees or the
relevant inventors during the prosecution of any of the Patents of the Company,

or, to its knowledge, potential liability with respect to any (i) deferred

nonqualified defined contribution or defined benefit plans or arrangements which
are employee pension benefit plans (as defined in Section 3(2) of ERISA), or
(iii) employee welfare benefit plans, (as defined in Section 3(1) of ERISA),
stock option or stock purchase plans, or material fringe benefit plans or
programs whether in writing or oral and whether or not terminated. The Company
has never contributed to any multiemployer pension plan (as defined in Section

          (b) With respect to each Company Benefit Plan that is intended to be a
"qualified plan" within the meaning of Section 401(a) of the Code, either (i)
the IRS has issued a favorable determination letter that has not been revoked,
or (ii) an application for a favorable determination letter was timely submitted
to the IRS for which no final action has been taken by the IRS. To the knowledge
of the Company, there is no reason that is not susceptible to cure why the
qualified status under Section 401(a) of the Code of any Company Benefit Plan
would be denied or revoked, whether retroactively or prospectively.

          (c) To the knowledge of the Company, no Company Benefit Plan, any
fiduciary thereof, nor the Company has incurred any liability or penalty under
Section 4975 of


                                       15
<PAGE>   16


the Code or Section 502(i) of ERISA. Except as would not have a Company Material
Adverse Effect, each Company Benefit Plan has been maintained and administered
in all material respects in compliance with its terms and with ERISA and the
Code, to the extent applicable thereto.

          (d) To the knowledge of the Company, neither the Company nor any ERISA
Affiliate (during the period of its affiliated status) has any existing
liability currently due and payable that has not been satisfied in full under
Title IV of ERISA or Section 412 of the Code. To the knowledge of the Company,
there are no current plans to terminate, whether voluntarily or involuntarily,
any materially underfunded pension plan of the Company or any ERISA Affiliate
that is subject to Title IV of ERISA.

          (e) To the knowledge of the Company, there is no pending or
anticipated claim, suit, action or other litigation against or otherwise
involving any of the Company Benefit Plans (excluding claims for benefits
incurred in the ordinary course of the Company Benefit Plan activities) except
those which would either have no Company Material Adverse Effect or those which
have been released, dismissed, settled or otherwise satisfied, each of which is
set forth in Section 4.12(e) of the Company Disclosure Schedule.

          (f) All material contributions required to be made as of the date
hereof to the Company Benefit Plans have been made or provided for.

          (g) Except as set forth in Schedule 4.12 of the Company Disclosure
Schedule, the execution of, and performance of the transactions contemplated by,
this Agreement will not (either alone or upon the occurrence of any additional
or subsequent events) constitute an event under any benefit plan, policy,
arrangement or agreement or any trust or loan that will or is reasonably likely
to result in any payment (whether of severance pay or otherwise), acceleration,
forgiveness of indebtedness, vesting, distribution, increase in benefits or
obligation to fund benefits with respect to any employee of the Company.

          (h) The Company has not entered into any severance agreements or
adopted any severance policies applicable to the Company or its employees which
would have a Company Material Adverse Effect or which have not either been
satisfied or provided for, and each such severance agreement and policy is set
forth on Section 4.12(h) of the Company Disclosure Schedule.

     4.13 NO BROKERS. The Company has not entered into any contract, arrangement
or understanding with any person or firm which will or is reasonably likely to
result in the obligation of the Company, Parent or Merger Sub to pay any
finder's fees, brokerage or agent's commissions or other like payments in
connection with the negotiations leading to this Agreement or the consummation
of the transactions contemplated hereby, except that the Company has retained
Quist Financial, Inc. to render a fairness opinion, the arrangements with which
have been disclosed in writing to Parent prior to the date hereof. Other than
the foregoing arrangements, the Company is not aware of any claim for payment of
any finder's fees, brokerage or agent's commissions or other like payments in
connection with the negotiations leading to this Agreement or the consummation
of the transactions contemplated hereby.

                                       20
<PAGE>   21


state any material fact required to be stated therein or necessary to make the
statements therein, in light of the circumstances under which they were made,
not misleading.

          (b) Each of the consolidated balance sheets of Parent included in or
incorporated by reference into the Parent Reports (including the related notes
and schedules) fairly presents in all material respects the consolidated
financial position of Parent and its Subsidiaries as of its date, and each of
the consolidated statements of income, stockholders' equity and cash flows of
Parent included in or incorporated by reference into the Parent Reports
(including any related notes and schedules) fairly presents in all material
respects the income, stockholders' equity and cash flows, as the case may be, of
Parent and its Subsidiaries for the periods set forth therein (subject, in the
case of unaudited statements, to normal year-end audit adjustments which would
not be material in amount or effect), in each case in accordance with GAAP,
except as may be noted therein and subject to the fact that unaudited financial
statements do not contain full notes thereto. Parent and its Subsidiaries do not
have any liabilities or obligations required to be disclosed in a consolidated
balance sheet or the notes thereto prepared in accordance with GAAP, except (i)
liabilities or obligations reflected on, or reserved against in, a consolidated
balance sheet of Parent or in the notes thereto, and included in the Parent
Reports, (ii) liabilities or obligations incurred since March 31, 2000 in the
ordinary course of business, consistent with past practices, or (iii)
liabilities disclosed in a Parent Report.

     5.6 POOLING OF INTERESTS; TAX REORGANIZATION. To the knowledge of Parent,
having sought and obtained the advice of its accounting advisors, neither Parent
nor any of its Subsidiaries has taken (or as of the date hereof failed to take)
any action which would prevent the accounting for the Merger as a pooling of
interests in accordance with APB No. 16, the interpretative releases issued
pursuant thereto, and the pronouncements of the Commission. To the knowledge of
Parent, neither Parent nor any of its Subsidiaries has taken or failed to take
any action which would prevent the Merger from constituting a reorganization
within the meaning of section 368 of the Code.

     5.7 ACCURACY OF DOCUMENTS AND INFORMATION. The copies of all instruments,
agreements, other documents and written information delivered by Parent to the
Company or its counsel are and will be complete and correct in all material
respects as of the date of delivery thereof. No representations or warranties
made by Parent in this Agreement, nor any document, written information,
statement, financial statement, letter, certificate or exhibit prepared and
furnished or to be prepared and furnished by Parent or its representatives to
the Company pursuant hereto or in connection with the transactions contemplated
hereby, contains or will contain any untrue statement of material fact, or omits
or will omit to state a material fact necessary to make the statements or facts
contained herein or therein not misleading. There is no presently existing
event, fact or condition that would have a Parent Material Adverse Effect or
that could reasonably be expected to do so, which has not been set forth in this
Agreement or the exhibits hereto.

     5.8 COMPANY OPTIONS. Parent acknowledges that the vesting of all Company
Options will accelerate at the Effective Time.

                                   COVENANTS

     6.1 ALTERNATIVE PROPOSALS.

          (a) Upon execution and delivery of this Agreement, the Company, its
affiliates and their respective officers, directors, employees, representatives
and agents shall immediately cease any existing discussions or negotiations, if
any, conducted with any parties heretofore with respect to any acquisition of
all or any material portion of the assets of, or any equity interest in, the
Company or any business combination with the Company. Notwithstanding the
foregoing, the Company may issue Company Common Stock issuable upon exercise of
the Company Options outstanding on the date hereof and pursuant to the Stock
Purchase Plan, subject to the limitations set forth in Section 3.2(d)(iv).

          (b) Prior to the Closing Date, the Company may, solely in response to
unsolicited requests therefor, furnish non-public information regarding itself
to any corporation, partnership, person or other entity or group in respect of,
and may participate in discussions and negotiate with such entity or group
concerning, a business combination, merger, sale of material assets, sale of
shares of capital stock or similar transaction involving the Company (a
"Transaction"), provided that (i) such entity or group has submitted a written
proposal to the Board of Directors of the Company relating to any such
Transaction (an "Alternative Proposal"), (ii) the entity or group enters into
confidentiality agreements with the Company with respect to such non-public
information, and (iii) the Company Board, by a majority vote, determines in its
good faith judgment, based as to legal matters on the written advice of legal
counsel, that failing to take such action would constitute a breach of the
Company Board's fiduciary duty. The Company Board shall provide a copy of any
such written proposal to Parent and Merger Sub immediately after receipt
thereof, unless prohibited by the terms of such proposal.

          (c) Neither the Company nor any of its affiliates, nor any of such
Persons' respective officers, directors, employees, representatives or agents,
shall, directly or indirectly (i) encourage, solicit, participate in or initiate
discussions or negotiations with, or provide any information to, any
corporation, partnership, person or other entity or group (other than Parent and
Merger Sub, any affiliate or associate of Parent and Merger Sub or any designees
of Parent and Merger Sub) concerning any Transaction, or (ii) authorize, propose
or announce an intention to authorize or propose any Transaction (other than the
Merger), unless and until the Company has received an Alternative Proposal in
writing and the Company Board, by majority vote, has determined in its good
faith judgment, based as to legal matters on the written advice of legal
counsel, that failing to take such action would constitute a breach of the
Company Board's fiduciary duty; provided, however, that nothing herein shall
prevent the Company Board from taking, and disclosing to the Company's
stockholders, a position contemplated by Rules 14d-9 and 14e-2 promulgated under
the Exchange Act with regard to any tender offers; provided, further, that the
Company Board shall not recommend that the stockholders of the Company tender
their shares in connection with any such tender offer unless the Company Board
by a majority vote determines in its good faith judgment, based as to legal
matters on the written advice of legal counsel, that failing to take such action
would constitute a breach of the Company Board's fiduciary duty.

terminate this Agreement (except as specifically provided in Article 8 hereof),
(ii) permit the Company to enter into any agreement with respect to a
Transaction during the term of this Agreement (it being agreed that during the
term of this Agreement, the Company shall not enter into any agreement with any
person that provides for, or in any way facilitates, a Transaction, other than a
confidentiality agreement in customary form), or (iii) except as specifically
provided in Article 8, affect any other obligation of the Company under this
Agreement.

               (ix) shall not grant, confer or award any options, appreciation

entity, except in the ordinary course of business;

               (xiv) shall not make any loans or advances to any other Person,
except in the ordinary course of business;

the Closing Date.

     6.3 MEETING OF STOCKHOLDERS. The Company will take all action necessary in
accordance with applicable law and its Articles of Incorporation and Bylaws to
convene a Stockholders' Meeting as promptly as practicable to consider and vote
upon the approval of this Agreement and the transactions contemplated hereby.
Unless the Company Board by a majority


                                       24
<PAGE>   25


vote determines in its good faith judgment, based as to legal matters on the
written advice of legal counsel, that taking such action would constitute a
breach of the Company Board's fiduciary duty, the Company Board shall recommend
such approval, and the Company shall take all lawful action to solicit such
approval, including, without limitation, timely mailing the Proxy
Statement/Prospectus.

     6.4 FILINGS; OTHER ACTIONS. Subject to the terms and conditions herein
provided, the Company and Parent shall: (a) use all reasonable efforts to
cooperate with one another in (i) determining which filings are required to be
made prior to the Effective Time with, and which other consents, approvals,
permits or authorizations are required to be obtained prior to the Effective
Time from, governmental or regulatory authorities of the United States, the
several states and foreign jurisdictions in connection with the execution and
delivery of this Agreement and the consummation of the transactions contemplated
hereby and (ii) timely making all such filings and timely seeking all such
consents, approvals, permits or authorizations; and (b) use all reasonable

its respective commitments, contracts, titles and financial position, or
otherwise pertaining to its respective business and affairs, (b) furnish to the

     6.6 PUBLICITY. The initial press release relating to this Agreement shall
be a joint press release and thereafter, until the Effective Time, the Company
and Parent shall, subject to their respective legal obligations (including
requirements of stock exchanges and similar self regulatory bodies), consult
with each other, and use reasonable efforts to agree upon the text of any press
release, before issuing any such press release or otherwise making public
statements with respect to the transactions contemplated hereby and in making
any filings with any federal or state governmental or regulatory agency or with
any national securities exchange with respect thereto.

     6.7 PROXY STATEMENT/PROSPECTUS.

          (a) Parent and the Company shall cooperate and promptly prepare and
Parent shall file with the Commission as soon as practicable a Registration
Statement on Form S-4 under the Securities Act (the "Registration Statement"),
with respect to the Parent Common Stock issuable in the Merger, which
Registration Statement shall contain the proxy statement with respect to the
meeting of the stockholders of the Company in connection with the Merger (the
"Proxy Statement/Prospectus").


                                       25
<PAGE>   26


          (b) The parties will cause the Proxy Statement/Prospectus, and Parent
will cause the Registration Statement, to comply as to form in all material
respects with the applicable provisions of the Securities Act, the Exchange Act
and the rules and regulations thereunder. Parent shall use all reasonable
efforts, and the Company shall cooperate with Parent, to have the Registration
Statement declared effective by the Commission as promptly as practicable.

          (c) The information supplied by the Company for inclusion or
incorporation by reference in the Proxy Statement/Prospectus and the
Registration Statement shall not (i) at the time the Registration Statement is
declared effective, (ii) at the time the Proxy Statement/Prospectus (or any
amendment thereof or supplement thereto) is first mailed to holders of Company
Common Stock, (iii) at the time of the Stockholders' Meeting, or (iv) at the

Act and the Exchange Act.

          (e) No amendment or supplement to the Proxy Statement/Prospectus will
be made by the Company or Parent without the approval of the other (except to
the extent such amendment or supplement incorporates by reference other filings
of the Company or Parent). Parent will advise the Company, promptly after it
receives notice thereof, of the time when the Registration Statement has become
effective or any supplement or amendment has been filed, the issuance of any
stop order, the suspension of the qualification of the Parent Common Stock
issuable in connection with the Merger for offering or sale in any jurisdiction,
or any request by the Commission for amendment of the Proxy Statement/Prospectus
or the Registration Statement or comments thereon and responses thereto or
requests by the Commission for additional information.

     6.8 AFFILIATE LETTERS. Promptly after the date hereof, the Company shall
deliver to Parent a list of names and addresses of those persons who were, in
the Company's reasonable judgment, as of the record date for the Stockholders'
Meeting, Affiliates of the Company. The Company shall provide Parent such
information and documents as Parent shall reasonably request with respect to
such Affiliates. The Company shall use all reasonable efforts to deliver or
cause to be delivered to Parent, prior to the Closing Date, from each of the
Affiliates of the Company identified in the foregoing list, an affiliate letter
in form and substance reasonably acceptable to Parent in order to satisfy the
requirements of Rule 145 of the Securities Act and APB No. 16 (collectively,
"Affiliate Letters"). Parent shall be entitled to place legends as


                                       26
<PAGE>   27


specified in such Affiliate Letters on the certificates evidencing any Parent
Common Stock to be received by such Affiliates pursuant to the terms of this
Agreement, and to issue appropriate stop transfer instructions to the transfer
agent for the Parent Common Stock, consistent with the terms of such Affiliate
Letters. Subject to the receipt by Parent of satisfactory representations and
warranties from the relevant holders and/or brokers, such legends shall be
removed and such transfer instructions terminated at the earliest possible date
under all applicable laws and regulations.

     6.9 EXPENSES. Whether or not the Merger is consummated, all costs and
expenses incurred in connection with this Agreement and the transactions
contemplated hereby shall be paid by the party incurring such expenses except as
expressly provided herein and except that the filing fee in connection with the
filing of the Registration Statement or Proxy Statement/Prospectus with the
Commission and the expenses incurred in connection with printing and mailing the
Registration Statement and the Proxy Statement/Prospectus shall be shared
equally by the Company and Parent.

     6.10 EMPLOYEE BENEFITS.

          (a) From and after the Effective Time, Parent shall provide or cause
the Surviving Corporation to provide to persons who are employees of the Company
at the Effective Time and who will continue as employees of the Surviving
Corporation after the Effective Time (the "Company Personnel") the same employee
compensation and benefit plans, programs and arrangements as are provided to
other employees of Parent employed in similar capacities to such Company
Personnel; provided, however, that subject to the foregoing, Parent shall not be
precluded from amending or terminating any particular plan, program or
arrangement, or from substituting any such plans, programs or arrangements with
plans, programs or arrangements applicable and available to other employees of
Parent and its Subsidiaries.

          (b) Following the Effective Time, Parent shall cause the benefit plans
covering the Company Personnel following the Effective Time (the "Future Benefit
Plans") to continue to recognize the service credit of the Company Personnel
accrued as of the Effective Time under the Company Benefit Plans for purposes of
participation, eligibility and vesting of benefits, to the extent permissible by
the terms of such Future Benefit Plans.

     6.11 AGREEMENTS. Between the date hereof and the Closing Date, the Company
shall not enter into any agreement which the Company knows or has reason to know
is reasonably likely to cause any major customer of the Company to terminate any
material contracts, agreements or other obligations that exist between that
customer on the one hand, and the Company (or the Company following the Merger),
on the other hand and the Company shall take all reasonable action appropriate
to an effort to avoid such termination.

     6.12 TAKEOVER STATUTE. If any "fair price," "moratorium," "control share
acquisition" or other form of anti-takeover statute or regulation shall become
applicable to the transactions contemplated hereby, the Company and the Company
Board shall grant such approvals and take such actions as are reasonably
necessary so that the transactions contemplated hereby may be consummated as
promptly as practicable on the terms contemplated hereby and otherwise act to
eliminate or minimize the effects of such statute or regulation on the
transactions contemplated

                                       27
<PAGE>   28


hereby; provided, however, that the Company and the Company Board shall not be
required to grant such approvals or take such actions if the Company Board, by
majority vote, determines in its good faith judgment, based as to legal matters
on the written advice of legal counsel, that granting such approvals or taking
such actions would constitute a breach of the Company's Board's fiduciary
duties.

     6.13 INTERIM OPERATIONS OF PARENT.

          (a) Prior to the Effective Time, except as contemplated by any other
provision of this Agreement, unless the Company has consented in writing
thereto, Parent:

               (i) shall promptly notify the Company of (A) any material adverse
change in its condition (financial or otherwise), business, properties, assets,
liabilities or the normal course of its business or of its properties, (B) any
material litigation or, to the extent known to Parent, any material governmental
complaints, investigations or hearings against or otherwise involving Parent (or
communications indicating that the same may be contemplated), or (C) the breach
of any representation or warranty of Parent contained herein;

               (ii) shall promptly deliver to the Company true and correct
copies of any report, statement or schedule filed by Parent with the Commission
subsequent to the date of this Agreement;

               (iii) shall not take any actions which would, or would be
reasonably likely to, prevent the Merger from qualifying as a reorganization
within the meaning of Section 368 of the Code;

               (iv) shall not take any actions which would, or would be
reasonably likely to, prevent the Merger from qualifying as a transaction to be
accounted for as a pooling of interests in accordance with APB No. 16; and

          (b) shall not agree, in writing or otherwise, to take any of the
foregoing actions or take any action which would make any representation or
warranty in Article 5 hereof untrue or incorrect in any material respect as of
the Closing Date.

     6.14 DIRECTORS' AND OFFICERS' INDEMNIFICATION AND INSURANCE.

          (a) The Articles of Incorporation and By-laws of the Surviving
Corporation shall contain the respective provisions that are set forth, as of
the date of this Agreement, in the Articles of Incorporation and the By-laws of
the Company dealing with indemnification of officers, directors and employees of
the Company and other persons specified therein, which provisions shall not be
amended, repealed or otherwise modified for a period of six years from the
Effective Time in any manner that would affect adversely the rights thereunder
with respect to actions or events occurring prior to the Effective Time of
individuals who were entitled to such indemnification prior to the Effective
Time.

          (b) The Surviving Corporation shall maintain in effect for at least
six years from the Effective Time directors' and officers' liability insurance
with an insurance company rated at least "A" by A.M. Best Company, covering the
persons who, as of the date of this


                                       28
<PAGE>   29


Agreement, are covered by the Company's directors' and officers' liability
insurance policy (the "Current Policy"). The coverage provided by the directors'
and officers' liability insurance maintained by the Surviving Corporation shall
be substantially similar to the coverage provided by the Current Policy.

          (c) Parent shall guarantee the obligations of the Surviving
Corporation provided by this Section 6.14.

          (d) This Section 6.14 shall survive the consummation of the Merger, is
intended to benefit the Company, the Surviving Corporation and each indemnified
party, and shall be enforceable by the indemnified parties.

     6.15 RULE 145 COMPLIANCE. For so long as resales of shares of Parent
Common Stock issued pursuant to the Merger are subject to the resale
restrictions set forth in Rule 145 under the Securities Act, Parent will use
reasonable efforts to comply with Rule 144(c)(1) under the Securities Act.

     6.16 TAX MATTERS. Each party represents and warrants to the other parties
that the statements in the proposed form of certificate of such party (each, a
"Party's Certificate" and, together, the "Parties' Certificates") to be
delivered by such party in connection with the opinions to be delivered pursuant
to Article 7 are true and correct as of the date hereof, assuming for purposes
of this sentence that the Merger had been consummated on the date hereof. Each
party agrees that, at and prior to the Effective Time, it will not take any
action that would cause any of the statements in such party's Party's
Certificate to be false as of the Effective Time. Unless (and then only to the
extent) otherwise required by a "determination" (as defined in Section
1313(a)(1) of the Code) or by a similar applicable provision of state or local
income or franchise tax law, each party agrees (i) to report the Merger on all
tax returns and other filings as a tax-free reorganization within the meaning of
Section 368(a) of the Code and (ii) not to take any position in any audit,
administrative proceeding or litigation that is inconsistent with the
characterization of the Merger as such a reorganization.

In the event any such order or injunction shall have been issued, each party
agrees to use its best efforts to have any such injunction lifted.

prohibiting the transactions contemplated by this Agreement and such order,

provided, that the party seeking to terminate this Agreement pursuant to this
paragraph (c) shall have used all reasonable efforts to remove such injunction,
order or decree; and provided, in the case of a termination pursuant to
paragraph (a) of this Section 8.2, that the terminating party shall not have

Merger by December 31, 2000.

Merger may be abandoned at any time prior to the Effective Time, before or after
the adoption and approval by the stockholders of the Company referred to in

curable or, if curable, is not cured within 30 days after written notice of such
breach is given by the Company to Parent, or (c) there has been a material
breach of any of the covenants or agreements set forth in this Agreement on the

     8.4 TERMINATION BY PARENT. This Agreement may be terminated and the Merger

(2) years after such termination, either the Company enters into any agreement
with respect to a Transaction whereby any third party shall acquire beneficial
ownership of more than 50% of the Company's (i) outstanding shares of voting
stock or (ii) assets (measured by fair market value), then the Company shall pay
Parent, by wire transfer of immediately available funds, a fee (the "Termination

          (b) The Company acknowledges that the agreements contained in this
Section 8.5 are an integral part of the transactions contemplated in this
Agreement, and that, without these agreements, Parent and Merger Sub would not
enter into this Agreement; accordingly, if the Company fails to promptly pay the
Termination Fee when due and, in order to obtain such payment, Parent or Merger
Sub commences a suit which results in a judgment against the Company, the
Company shall reimburse Parent for its costs and expenses (including attorneys'
fees) incurred in connection with such suit, together with interest on the
amount of the Termination Fee at the prime rate, as then quoted in The Wall
Street Journal, from the date the Termination Fee was required to be paid.

          (c) In the event of termination of this Agreement and the abandonment
of the Merger pursuant to this Article 8, all obligations of the parties hereto
shall terminate, except (i) the obligations of the parties set forth in this
Section 8.5 and Section 6.9, (ii) the provisions of Sections 9.3, 9.6, 9.9 and
9.13, and (iii) the Confidentiality Agreement previously executed between the
Company and Parent (the "Confidentiality Agreement"). Moreover, in the event of
termination of this Agreement pursuant to Section 8.3 or 8.4, nothing herein
shall prejudice the ability of the nonbreaching party from seeking damages,
after taking into account payment of the Termination Fee, if such fee has been
paid, from any other party for any willful breach of this Agreement, including
without limitation, attorneys' fees and the right to pursue any remedy at law or
in equity.

     8.6 EXTENSION; WAIVER. At any time prior to the Effective Time, any party
hereto, by action taken by its Board of Directors, may, to the extent legally

other acts of the other parties hereto, (b) waive any inaccuracies in the
representations and warranties made to such party contained herein or in any
document delivered pursuant hereto and (c) waive compliance with any of the
agreements or conditions for the benefit of such party contained herein. Any
agreement on the part of a party hereto to any such extension or waiver shall be

party.

                               GENERAL PROVISIONS

     9.1 NONSURVIVAL OF REPRESENTATIONS, WARRANTIES AND COVENANTS. The
representations, warranties and covenants in this Agreement or in any instrument
delivered pursuant to this Agreement shall not survive the Merger; provided,
however, that the covenants contained in Article 3, Section 6.9, Section 6.14

taking such action of compliance with any representations, warranties, covenants

breach of any provision hereunder shall not operate or be construed as a waiver
of any prior or subsequent breach of the same or any other provision hereunder.

Exhibits attached hereto and referred to herein are hereby incorporated herein
and made a part hereof for all purposes as if fully set forth herein.

rendering invalid or unenforceable the remaining terms and provisions of this
