split, stock dividend (including any dividend or distribution of securities
convertible into Parent Common Stock or Company Common Stock), extraordinary
cash dividends, reorganization, recapitalization, reclassification, combination,
exchange of shares or other like change with respect to Parent Common Stock

Annual Meeting of Stockholders of Parent to be held on November 8, 2000) (the

hereof and prior to the Effective Time.

            (f) Fractional Shares. No fraction of a share of Parent Common Stock

event of a good faith dispute as to the accuracy of the price reported therein,
another authoritative source reasonably agreed on by the parties hereto), of one
(1) share of Parent Common Stock for the five (5) consecutive trading days

Time, Parent shall make available to the Exchange Agent for exchange in
accordance with this Article I, the shares of Parent Common Stock issuable
pursuant to Section 1.6 hereof in exchange for outstanding shares of Company
Common Stock, and cash in an amount estimated to be sufficient for payment in
lieu of fractional shares pursuant to Section 1.6(f) hereof, and any dividends
or distributions to which holders of shares of Company Common Stock may be
entitled pursuant to Section 1.7(d) hereof.

            (c) Exchange Procedures. Promptly following the Effective Time,
Parent shall cause the Exchange Agent to mail to each holder of record (as of
the Effective Time) of a certificate or certificates (each, a "Certificate" and,
collectively, the "Certificates"), which immediately prior to the Effective Time

1.6(f)

                                      -5-

hereof, and any dividends or other distributions pursuant to Section 1.7(d)
hereof, (i) a letter of transmittal in customary form (which shall specify that
delivery shall be effected, and risk of loss and title to the Certificates shall
pass, only upon delivery of the Certificates to the Exchange Agent and shall
contain such other provisions as Parent may reasonably specify) and (ii)
instructions for use in effecting the surrender of the Certificates in exchange
for certificates representing shares of Parent Common Stock, cash in lieu of any
fractional shares pursuant to Section 1.6(f) hereof, and any dividends or other
distributions pursuant to Section 1.7(d) hereof. Upon surrender of Certificates
for cancellation to the Exchange Agent or to such other agent or agents as may
be reasonably appointed by Parent, together with such letter of transmittal,
duly completed and validly executed in accordance with the instructions thereto,
the holders of such Certificates shall be entitled to receive in exchange
therefor certificates representing the number of whole shares of Parent Common
Stock into which their shares of Company Common Stock were converted at the
Effective Time pursuant to Section 1.6 hereof, payment in lieu of fractional
shares which such holders have the right to receive pursuant to Section 1.6(f)
hereof, and any dividends or other distributions payable pursuant to Section
1.7(d), and the Certificates so surrendered shall forthwith be canceled. Until
so surrendered, outstanding Certificates shall be deemed from and after the
Effective Time, for all corporate purposes, subject to Section 1.7(d) hereof as
to dividends and other distributions, to evidence only the ownership of the
number of full shares of Parent Common Stock into which such shares of Company
Common Stock shall have been so converted pursuant to Section 1.6 hereof, and
the right to receive an amount in cash in lieu of the issuance of any fractional
shares pursuant to Section 1.6(f) hereof and any dividends or other
distributions payable pursuant to Section 1.7(d) hereof.

            (d) Distributions With Respect to Unexchanged Shares. No dividends
or other distributions declared or made after the date of this Agreement with
respect to Parent Common Stock with a record date after the Effective Time will
be paid to the holders of any unsurrendered Certificates with respect to the
shares of Parent Common Stock represented thereby until the holders of record of
such Certificates shall surrender such Certificates. Subject to applicable law,
following surrender of any such Certificates, the Exchange Agent shall deliver
to the record holders thereof, without interest, certificates representing whole
shares of Parent Common Stock issued in exchange therefor along with payment in
lieu of fractional shares pursuant to Section 1.6(f) hereof and the amount of
any such dividends or other distributions with a record date after the Effective
Time payable with respect to such whole shares of Parent Common Stock.

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

            (f) Required Withholding. 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 under 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.

            (g) No Liability. Notwithstanding anything to the contrary in this
Section 1.7, neither the Exchange Agent, Parent, the Surviving Corporation nor
any other party hereto shall be liable to a holder of shares of Parent Common
Stock or Company Common Stock for any amount properly paid to a public official
pursuant to any applicable abandoned property, escheat or similar law.

        1.8 No Further Ownership Rights in Company Common Stock. All shares of
Parent Common Stock issued in accordance with the terms hereof (including any
cash paid in respect thereof pursuant to Section 1.6(f) or Section 1.7(d)
hereof) shall be deemed to have been issued in full satisfaction of all rights
pertaining to such shares of Company Common Stock, and there shall be no further
registration of transfers on the records of the Surviving Corporation of shares
of Company Common Stock which were outstanding immediately prior to the
Effective Time. If, at any time following the Effective Time, Certificates are
presented to the Surviving Corporation for any reason, they shall be canceled
and exchanged as provided in this Article I.

        1.9 Lost, Stolen or Destroyed Certificates. In the event that any
Certificates shall have been lost, stolen or destroyed, the Exchange Agent shall
issue in exchange for such lost, stolen or destroyed Certificates, upon the
making of an affidavit of that fact by the holder thereof, certificates
representing the shares of Parent Common Stock into which the shares of Company
Common Stock represented by such Certificates were converted pursuant to Section
1.6 hereof, cash for fractional shares, if any, as may be required pursuant to
Section 1.6(f) hereof and any dividends or distributions payable pursuant to
Section 1.7(d) hereof; provided, however, that Parent and the Exchange Agent
may, in their discretion and as a condition precedent to the issuance of such
certificates representing shares of Parent Common Stock, cash and other
distributions, require the owner of such lost, stolen or destroyed Certificates
to deliver a bond in such sum as it may reasonably direct as indemnity against
any claim that may be made against Parent, the Surviving Corporation or the
Exchange Agent with respect to the Certificates alleged to have been lost,
stolen or destroyed.

        1.10 Tax and Accounting Consequences.

            (a) Tax. It is intended by the parties hereto that the Merger shall
constitute a reorganization within the meaning of Section 368 of the Code. The

following the Effective Time, any further action is necessary or desirable to
carry out the purposes and intent of this Agreement and to vest the Surviving
Corporation with full right, title and possession to all assets, property,
rights, privileges, powers and franchises of the Company and Merger Sub, the
officers and directors of the Company and Merger Sub shall take all such lawful
and necessary action.

except for (i) applicable requirements, if any, of the Securities Act of 1933,
as amended (the "Securities Act"), the Securities Exchange Act of 1934, as
amended (the "Exchange Act"), and state securities laws ("Blue Sky Laws"), the

Adverse Effect (as defined in Section 8.3(c) hereof) on the parties hereto,
prevent or materially delay consummation of the Merger or otherwise prevent the
parties hereto from performing their obligations under this Agreement.

        2.6 Compliance; Permits.

Company or any of its subsidiaries is a party or by which the Company or any of
its subsidiaries or its or any of their respective properties is bound or
affected, except for any conflicts, defaults or violations that (individually or
in the aggregate) would not cause the Company to lose any material benefit or
incur any material liability. No investigation or review by any governmental or
regulatory body or authority is, to the knowledge of the Company, pending or
threatened against the Company or its subsidiaries, nor has any governmental or
regulatory body or authority indicated an intention to conduct the same, other
than, in each such case, those the outcome of which could not, individually or
in the aggregate, reasonably be expected to have the effect of prohibiting or

subsidiaries, any acquisition of material property by the Company or any of its
subsidiaries or the conduct of business by the Company or any of its

misleading. None of the Company's subsidiaries is required to file any reports
or other documents with the SEC.

            (b) Each set of consolidated financial statements (including, in
each case, any related notes thereto) contained in the Company SEC Reports was
prepared in accordance with generally accepted accounting principles ("GAAP")
applied on a consistent basis throughout the periods involved (except as may be
indicated in the notes thereto or, in the case of unaudited statements, do not
contain footnotes as permitted by Form 10-Q of the Exchange Act) and each fairly
presents the consolidated financial position of the Company and its subsidiaries
as at the respective dates thereof and the consolidated results of its
operations and cash flows for the periods indicated, except that the unaudited
interim financial statements were or are subject to normal adjustments which
were not or are not expected to be material in amount.

            (c) The Company has previously furnished to Parent a complete and
correct copy of any amendments or modifications, which have not yet been filed

the consolidated financial statements prepared in accordance with GAAP which
are, individually or in the aggregate, material to the business, results of
operations or financial condition of the Company and its subsidiaries taken as a
whole, except (i) liabilities provided for in the Company's balance sheet as of
June 30, 2000 or (ii) liabilities incurred since June 30, 2000 in the ordinary
course of business, none of which is material to the business, results of
operations or financial condition of the Company and its subsidiaries, taken as
a whole.

established, maintained and administered in compliance with its terms and
conditions and with the requirements prescribed by any and all statutory or
regulatory laws that are applicable to such International Employee Plan.
Furthermore, no International Employee Plan has unfunded liabilities, that as of

<PAGE>   29

the agreements, contracts or commitments to which the Company or any of its
subsidiaries is a party or by which it is bound that are required to be set
forth in the Company Disclosure Letter (any such agreement, contract or
commitment, a "Company Contract") in such a manner as would permit any other
party to cancel or terminate any such Company Contract, or would permit any
other party to seek material damages or other remedies (for any or all of such
breaches, violations or defaults, in the aggregate).

        2.21 Insurance. The Company maintains insurance policies and fidelity
bonds covering the assets, business, equipment, properties, operations,
employees, officers and directors of the Company and its subsidiaries
(collectively, the "Insurance Policies") which the Company reasonably believes
are of the type and in amounts customarily carried by persons conducting
businesses similar to those of the Company and its subsidiaries. There is no
material claim by the Company or any of its subsidiaries pending under any of
the material Insurance Policies as to which coverage has been questioned, denied
or disputed by the underwriters of such policies or bonds. The Company is not
aware of, and has not received notice under any Insurance Policies of, (i) an
insurer's intention or threat to cancel or terminate any of the Insurance
Policies, (ii) an insurer's intention or threat to increase the premiums due
under any of the Insurance Policies.

        2.22 Opinion of Financial Advisor. The Company has received the opinion
of its financial advisor, Goldman Sachs & Co., to the effect that, as of the

Company and is on terms that are fair to such stockholders, and (iv) recommended
that the stockholders of Company approve and adopt this Agreement and approve
the Merger.

        2.24 Vote Required. The affirmative vote of the holders of a majority of
the outstanding shares of Company Common Stock is the only vote of the holders
of any class or series of the Company's capital stock necessary to approve and
adopt this Agreement and approve the Merger.

        2.25 State Takeover Statutes. The Board of Directors of the Company has
approved the Merger, this Agreement, the Stock Option Agreement and the Voting
Agreements, and such approval is sufficient to render inapplicable to the
Merger, this Agreement, the Stock Option Agreement and the Voting Agreements and
the transactions contemplated by this Agreement, the Stock Option Agreement and
the Voting Agreements, the provisions of Section 203 of the Delaware Law to the
extent, if any, such Section is applicable to the Merger, this Agreement, the
Stock Option Agreement and the Voting Agreements and the transactions
contemplated by this Agreement, the Stock Option Agreement and the Voting
Agreements. No other state takeover statute or similar statute or regulation
applies to or purports to apply to the Merger, this

Statement/Prospectus, the Registration Statement or any Other Filing, the
Company or Parent, as

                                      -36-
<PAGE>   38

the case may be, shall promptly inform the other of such occurrence and
cooperate in filing with the SEC or its staff or any other government officials,
and/or mailing to the stockholders of the Company, such amendment or supplement.

            (b) The Proxy Statement/Prospectus shall include (i) the unanimous
recommendation of the Board of Directors of the Company in favor of adoption and
approval of this Agreement and approval of the Merger, subject to the right of
the Board of Directors of the Company to withhold, withdraw, amend, modify or
change its recommendation and recommend a Superior Offer in accordance with
Section 5.2(c) hereof, and (ii) the opinion of Goldman Sachs & Co. referred to
in Section 2.22 hereof.

        5.2 Meeting of Company Stockholders.

            (a) Promptly after the date hereof, the Company shall take all
action necessary in accordance with Delaware Law and its Certificate of
Incorporation and Bylaws to convene a meeting of the stockholders of the Company
(the "Company Stockholders' Meeting") to be held as promptly as practicable, and
in any event (to the extent permissible under Delaware Law and the Certificate
of Incorporation and Bylaws of the Company) within forty five (45) calendar
days, following the declaration of effectiveness of the Registration Statement,
for the purpose of voting upon this Agreement and the Merger. Subject to the
terms of Section 5.2(c) hereof, the Company shall use commercially reasonable
efforts to solicit from its stockholders proxies in favor of the adoption and
approval of this Agreement and the approval of the Merger, and shall take all
other commercially reasonable action necessary or advisable to secure the vote
or consent of its stockholders required by the rules of The Nasdaq Stock Market,
Inc. or Delaware Law to obtain such approvals. The Company may adjourn or
postpone the Company Stockholders' Meeting (i) if and to the extent necessary to
ensure that any necessary supplement or amendment to the Proxy
Statement/Prospectus is provided to the Company's stockholders in advance of a
vote on this Agreement and the Merger, or (ii) if, as of the time for which the
Company Stockholders' Meeting is originally scheduled (as set forth in the 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 shall
ensure that the Company Stockholders' Meeting is called, noticed, convened, held
and conducted, and that all proxies solicited by the Company in connection with
the Company Stockholders' Meeting are solicited, in compliance with Delaware
Law, and the Certificate of Incorporation and Bylaws of the Company, the rules
of The Nasdaq Stock Market, Inc. and all other applicable legal requirements.
Notwithstanding anything to the contrary contained in this Agreement, the
Company's obligation to call, give notice of, convene and hold the Company
Stockholders' Meeting in accordance with this Section 5.2(a) shall not be
limited to or otherwise affected by the commencement, disclosure, announcement
or submission to the Company of any Acquisition Proposal (as defined below), or
by any withholding, withdrawal, amendment, modification or change of the
recommendation of the Board of Directors of the Company with respect to this
Agreement and/or the Merger.

            (b) Unless the Board of Directors of the Company shall have
withheld, withdrawn, amended, modified or changed its recommendation of this
Agreement and the Merger in compliance with Section 5.2(c) hereof: (i) the Board
of Directors of the Company shall

                                      -37-
<PAGE>   39

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 Proxy Statement/Prospectus 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
withhold, withdraw, amend, modify, change or propose or resolve to withhold,
withdraw, amend, modify or change, in each case 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 all purposes of and under this Agreement, the foregoing
recommendation of the Board of Directors of the Company shall be deemed to have
been modified in a manner adverse to Parent if such recommendation by the Board
of Directors of the Company or any committee thereof shall no longer be
unanimous.

            (c) Nothing in this Agreement shall prevent the Board of Directors
of the Company from withholding, withdrawing, amending, modifying or changing
its unanimous recommendation in favor of the adoption and approval of this
Agreement and approval of the Merger if (i) a Superior Offer (as defined below)
is made to the Company and is not withdrawn, (ii) neither the Company nor any of
its representatives shall have violated the terms of Section 5.5 hereof and the
Company is not then in material breach of this Agreement, and (iii) the Board of
Directors of the Company reasonably concludes in good faith, after consultation
with its outside counsel, that, in light of such Superior Offer, the
withholding, withdrawal, amendment, modification or changing of such
recommendation is required in order for the Board of Directors of the Company to
comply with its fiduciary obligations to the Company's stockholders under
Delaware Law with respect to such Superior Offer; provided, however, that prior
to publicly withholding, withdrawing, amending, modifying or changing its
recommendation in favor of the adoption and approval of this Agreement and
approval of the Merger, the Company shall have given Parent at least three (3)
business days prior written notice (or such lesser prior notice as provided to
the members of Company's Board of Directors) thereof and the opportunity to meet
with the Company and its counsel. Nothing contained in this Section 5.2 shall
limit the Company's obligation to hold and convene the Company Stockholders'
Meeting (regardless of whether the unanimous recommendation of the Board of
Directors of the Company shall have been withheld, withdrawn, amended, modified
or changed pursuant hereto). As used in this Agreement, the term "Superior
Offer" shall mean any bona fide, unsolicited written Acquisition Proposal (as
defined in Section 5.5(b) hereof) for all of the outstanding shares of Company
Common Stock on terms that the Board of Directors of the Company determines in
good faith, after considering the advice of a financial advisor of nationally
recognized reputation and taking into account all the terms and conditions of
the Acquisition Proposal, are more favorable to the Company's stockholders than
the terms of the Merger; provided, however, that any such offer shall not be
deemed to be a "Superior Offer" pursuant hereto if any financing required to
consummate the transaction contemplated by such offer is both not committed and
not likely, in the judgment of the Board of Directors of the Company, to be
obtained by such third party on a timely basis.

        5.3 Confidentiality. The parties hereto acknowledge that the Company and
Parent have previously executed a Confidential Disclosure Agreement, dated as of
September 8, 2000

                                      -38-
<PAGE>   40

(the "Confidentiality Agreement"), which Confidentiality Agreement will continue
in full force and effect in accordance with its terms.

        5.4 Access to Information. During the period commencing with the
execution and delivery of this Agreement until the earlier to occur of the
termination of this Agreement pursuant to its terms and the Effective Time, the
Company shall afford Parent and its accountants, counsel and other
representatives reasonable access during normal business hours to the
properties, books, records and personnel of the Company to obtain all
information concerning the business of the Company, including, without
limitation, the status of the Company's product development efforts, properties,
results of operations and personnel, as Parent may reasonably request. No
information or knowledge obtained by Parent during the course of any
investigation conducted pursuant to this Section 5.4 shall affect, or be deemed
to modify in any respect any representation or warranty contained herein or the
conditions to the obligations of the parties to consummate the Merger contained
herein.

        5.5 No Solicitation.

            (a) During the period commencing with the execution and delivery of
this Agreement until the earlier to occur of the termination of this Agreement
pursuant to its terms and the Effective Time, the Company and its subsidiaries
shall not, nor will they authorize or permit any of their respective officers or
directors, or any investment banker, attorney or other advisor or representative
retained by any of them to, nor will they authorize any of their respective
affiliates or employees to, or indirectly, (i) solicit, initiate, knowingly
encourage or induce the making, submission or announcement of any Acquisition
Proposal (as defined in Section 5.5(b) hereof), (ii) participate in any
discussions or negotiations regarding, or furnish to any person any information
with respect to, or take any other action to knowingly facilitate any inquiries
or the making of any proposal that constitutes or may reasonably be expected to
lead to, any Acquisition Proposal, (iii) engage in discussions or negotiations
with any person with respect to any Acquisition Proposal (it being understood
and agreed that informing any person as to the existence of these provisions, or
requesting additional information regarding the terms and conditions of any
Acquisition Proposal from the person making such Acquisition Proposal, without
in each case providing additional information, shall not constitute a discussion
or negotiation in violation of this Section 5.5(a)), (iv) subject to the terms
of Section 5.2(c) hereof, approve, endorse or recommend any Acquisition
Proposal, or (v) enter into any letter of intent or similar document or any
contract, agreement or commitment contemplating or otherwise relating to any
Acquisition Transaction; provided, however, that prior to the adoption and
approval of this Agreement and the approval of the Merger by the requisite vote
of the stockholders of the Company, nothing in this Agreement (including the
first sentence of this Section 5.5(a)) shall prohibit the Company from
furnishing information regarding the Company or any of its subsidiaries to, or
entering into a confidentiality agreement with, or entering into or conducting
discussions or negotiations with, any person or group in response to a Superior
Offer submitted by such person or group (and not withdrawn) if (1) neither the
Company nor any representative of the Company and its subsidiaries shall have
violated any of the restrictions set forth above in this Section 5.5, (2) the
Board of Directors of the Company concludes in good faith, after consultation
with its outside legal counsel, that such action is required in order for the
Board of Directors of the Company to comply with its fiduciary obligations to
the Company's stockholders

                                      -39-
<PAGE>   41

under Delaware Law (3) at least three (3) business days prior to furnishing any
such information to, or entering into discussions or negotiations with, such
person or group, the Company gives Parent written notice of the identity of such
person or group and of the Company's intention to furnish information to, or
enter into discussions or negotiations with, such person or group, and (y) the
Company receives from such person or group an executed confidentiality agreement
at least as restrictive as the Confidentiality Agreement, and (4)
contemporaneously with furnishing any such information to such person or group,
the Company furnishes such information to Parent (to the extent such information
has not been previously furnished by the Company to Parent). In addition,
nothing in this Agreement shall prohibit the Company from complying with Rule
14e-2 promulgated under the Exchange Act with regard to an Acquisition Proposal.
The Company and its subsidiaries shall immediately cease any and all existing
activities, discussions or negotiations with any parties conducted heretofore
with respect to any Acquisition Proposal. Without limiting the generality of the
foregoing, the parties hereto understand and agree that any violation of the
restrictions set forth in this Section 5.5(a) by any officer or director of the
Company or any of its subsidiaries or any investment banker, attorney or other
advisor or representative of the Company or any of its subsidiaries shall be
deemed to be a breach of this Section 5.5(a) by the Company. In addition to the
foregoing, the Company shall (i) provide Parent with at least forty eight (48)
hours prior notice (or such lesser prior notice as provided to the members of
the Board of Directors of the Company, but in no event less than twelve (12)
hours unless the Company shall have previously notified Parent of a prior
meeting of the Board of Directors of the Company to consider such Superior
Offer) of any meeting of the Board of Directors of the Company at which the
Board of Directors of the Company is reasonably expected to consider a Superior
Offer, and (ii) provide Parent with at least three (3) business days prior
written notice (or such lesser prior notice as provided to the members of the
Board of Directors of the Company) of a meeting of the Board of Directors of the
Company at which the Board of Directors of the Company is reasonably expected to
recommend a Superior Offer to the stockholders of the Company and together with
such notice a copy of the proposed form of agreement, letter of intent or other
definitive document containing the terms and conditions of such Superior Offer.

            (b) For all purposes of and under this Agreement, the term
"Acquisition Proposal" shall mean any offer or proposal (other than an offer or
proposal by Parent) providing for any Acquisition Transaction. For all purposes
of and under this Agreement, the term "Acquisition Transaction" shall mean any
transaction or series of related transactions, other than the transactions
contemplated by this Agreement, involving: (i) any acquisition or purchase from
the Company by any person or "group" (as defined under Section 13(d) of the
Exchange Act and the rules and regulations promulgated thereunder) of more than
a fifteen percent (15%) interest in the total outstanding voting securities of
the Company or any of its subsidiaries, or any tender offer or exchange offer
that if consummated would result in any person or "group" (as defined under
Section 13(d) of the Exchange Act and the rules and regulations thereunder)
beneficially owning fifteen percent (15%) or more of the total outstanding
voting securities of the Company or any of its subsidiaries, or any merger,
consolidation, business combination or similar transaction involving the Company
pursuant to which the stockholders of the Company immediately preceding such
transaction would hold less than eighty-five percent (85%) of the equity
interests in the surviving or resulting entity of such transaction; (ii) any
sale, lease (other than in the ordinary course of business), exchange, transfer,
license (other than in the ordinary

                                      -40-
<PAGE>   42

course of business), acquisition or disposition of more than fifteen percent
(15%) of the assets of the Company; or (iii) any liquidation or dissolution of
the Company.

            (c) In addition to the obligations of the Company set forth in
Section 5.5(a) hereof, the Company shall advise Parent, as promptly as
practicable, and in any event within twenty four (24) hours, orally and in
writing, of (i) any request for information which the Company reasonably
believes is likely to lead to an Acquisition Proposal or, (ii) any Acquisition
Proposal, or (iii) any inquiry with respect to or which the Company reasonably
believes could lead to any Acquisition Proposal, the (iv) material terms and
conditions of any such request, Acquisition Proposal or inquiry, and (v) the
identity of the person or group making any such request, Acquisition Proposal or
inquiry. The Company shall keep Parent informed in all material respects of the
status and details (including material amendments or proposed amendments) of any
such request, Acquisition Proposal or inquiry.

        5.6 Public Disclosure. Parent and the Company shall consult with each
other, and to the extent practicable, agree, before issuing any press release or
otherwise making any public statement with respect to this Agreement, the Merger
or an Acquisition Proposal, and shall not issue any such press release or make
any such public statement prior to such consultation, except as may be required
by applicable law or any listing agreement with a national securities exchange
or The Nasdaq Stock Market, Inc. The parties hereto have agreed to the text of
the joint press release announcing the signing of this Agreement.

        5.7 Reasonable Efforts; Notification.

            (a) Upon the terms and subject to the conditions and limitations set
forth in this Agreement (including, without limitation, the Company's rights
under Section 5.2 and Section 5.5 hereof), each of the parties hereto shall use
its commercially reasonable best efforts to take, or cause to be taken, all
actions, and to do, or cause to be done, and to assist and cooperate with the
other parties hereto in doing, all things necessary, proper or advisable to
consummate and make effective, in the most expeditious manner practicable, the
Merger and the other transactions contemplated by this Agreement, including,
without limitation, using reasonable efforts to accomplish the following: (i)
the taking of all reasonable actions necessary to cause the conditions precedent
set forth in Article VI hereof to be satisfied, (ii) the obtaining of all
necessary actions or nonactions, waivers, consents, approvals, orders and
authorizations from Governmental Entities, and the making of all necessary
registrations, declarations and filings (including registrations, declarations
and filings with Governmental Entities, if any), and the taking of all
reasonable steps as may be necessary to avoid any suit, claim, action,
investigation or proceeding by any Governmental Entity, (iii) the obtaining of
all necessary consents, approvals or waivers from third parties which may be
required or desirable as a result of, or in connection with, the transactions
contemplated by this Agreement, (iv) the defending of any suits, claims,
actions, investigations or proceedings, whether judicial or administrative,
challenging this Agreement or the consummation of the transactions contemplated
hereby, including, without limitation, seeking to have any stay or temporary
restraining order entered by any court or other Governmental Entity vacated or
reversed, and (v) the execution or delivery of any additional certificates,
instruments and other documents necessary to consummate the transactions
contemplated by, and to fully carry out the purposes of, this Agreement. In

                                      -41-
<PAGE>   43

connection with and without limiting the foregoing, but subject to the
conditions and limitations set forth in this Agreement (including, without
limitation, the Company's rights under Section 5.2 and Section 5.5 hereof) the
Company and its Board of Directors shall, if any state takeover statute or
similar statute or regulation is or becomes applicable to the Merger, this
Agreement or any of the transactions contemplated by this Agreement, use
commercially reasonable efforts to ensure that the Merger and the other
transactions contemplated by this Agreement may be consummated as promptly as
practicable on the terms contemplated by this Agreement and otherwise to
minimize the effect of such statute or regulation on the Merger, this Agreement
and the transactions contemplated hereby. Notwithstanding anything to the
contrary in this Agreement, nothing in this Agreement shall be deemed to require
Parent or the Company or any subsidiary or affiliate thereof to agree to any
divestiture by itself or any of its affiliates of shares of capital stock or of
any business, assets or property, or the imposition of any material limitation
on the ability of any of them to conduct their businesses or to own or exercise
control of such assets, properties and stock.

            (b) The Company shall give prompt notice to Parent upon becoming
aware that any representation or warranty made by the Company in this Agreement
has become untrue or inaccurate, or that the Company has failed to comply with
or satisfy in any material respect any covenant, condition or agreement to be
complied with or satisfied by it under this Agreement, in each case, such that
the conditions set forth in Section 6.3(a) or Section 6.3(b) hereof would not be
satisfied, provided, however, that no such notification shall affect the
representations, warranties, covenants or agreements of the Company, or the
conditions to the obligations of the parties under this Agreement.

            (c) Parent shall give prompt notice to the Company upon becoming
aware that any representation or warranty made by Parent or Merger Sub in this
Agreement has become untrue or inaccurate, or that Parent or Merger Sub has
failed to comply with or satisfy in any material respect any covenant, condition
or agreement to be complied with or satisfied by it under this Agreement, in
each case, such that the conditions set forth in Section 6.2(a) or Section
6.2(b) hereof would not be satisfied, provided, however, that no such
notification shall affect the representations, warranties, covenants or
agreements of Parent or Merger Sub, or the conditions to the obligations of the
parties under this Agreement.

        5.8 Third Party Consents. As soon as practicable following the date
hereof, Parent and the Company shall each use its respective commercially
reasonable efforts to obtain any consents, waivers and approvals under any of
its or its subsidiaries' respective agreements, contracts, licenses or leases
required to be obtained in connection with the consummation of the transactions
contemplated hereby and by the Stock Option Agreement.

        5.9 Company Stock Options; Employee Stock Purchase Plan.

            (a) Company Stock Options. At the Effective Time, each outstanding
option to purchase shares of Company Common Stock (each, a "Company Stock
Option") under any Company Stock Plan, whether or not vested, shall be assumed
by Parent by virtue of the Merger and without any action on the part of Parent,
the Company or any holders of Company Stock Options, and, to the extent required
under any Company Stock Plan, Parent shall issue

                                      -42-
<PAGE>   44

assumption agreements to all holders of Company Stock Options within thirty (30)
calendar days following the Effective Time. Each Company Stock Option so assumed
by Parent under this Agreement shall continue to have, and be subject to, the
same terms and conditions of such options immediately prior to the Effective
Time (including, without limitation, any repurchase rights or vesting
provisions, but after giving effect to the amendments entered into pursuant to
Section 6.3(b) hereof), except that (i) each Company Stock Option shall be
exercisable (or will become exercisable in accordance with its terms) for that
number of whole shares of Parent Common Stock equal to the product obtained by
multiplying (x) the number of shares of Company Common Stock that were issuable
upon the exercise in full of such Company Stock Option immediately prior to the
Effective Time, by (y) the Exchange Ratio, rounded down to the nearest whole
number of shares of Parent Common Stock, and (ii) the per share exercise price
for the shares of Parent Common Stock issuable upon the exercise of each such
assumed Company Stock Option shall be equal to the quotient obtained by dividing
(x) the exercise price per share of Company Common Stock at which such Company
Stock Option was exercisable immediately prior to the Effective Time, by (y) the
Exchange Ratio, rounded up to the nearest whole cent.

            (b) Employee Stock Purchase Plan. Prior to the Effective Time,
outstanding purchase rights under the Employee Stock Purchase Plan shall be
exercised in accordance with Section 19 of the Employee Stock Purchase Plan, and
each share of Company Common Stock purchased pursuant to such exercise shall by
virtue of the Merger, and without any action on the part of the holder thereof,
be converted into the right to receive a number of shares of Parent Common Stock
equal to the Exchange Ratio, without issuance of certificates representing
issued and outstanding shares of Company Common Stock to participants under the
Employee Stock Purchase Plan. The Company shall terminate the Employee Stock
Purchase Plan, effective at or prior the Closing.

        5.10 Form S-8. As soon as is reasonably practicable following the
Effective Time, to the extent available for use by Parent, Parent shall file a
registration statement on Form S-8 (or any successor form thereto) to register
under the Securities Act the issuance of the shares of Parent Common Stock
issuable upon the exercise of all Company Stock Options assumed by parent
pursuant to Section 5.9 hereof, to the extent that the issuance of such shares
may be registered on Form S-8 (or any successor form thereto).

        5.11 Indemnification; Directors' and Officers' Insurance.

            (a) From and after the Effective Time, Parent shall, and shall cause
the Surviving Corporation to, fulfill and honor in all respects the obligations
of the Company and its subsidiaries under any indemnification agreements between
(i) the Company or any of its subsidiaries and (ii) any of their respective
directors and officers, as in effect on the date hereof (the "Indemnified
Parties"), and any indemnification provisions in the Company's Certificate of
Incorporation or Bylaws, as in effect on the date hereof, or in any equivalent
organizational documents of any subsidiary of the Company, as the case may be.
The Certificate of Incorporation and Bylaws of the Surviving Corporation shall
contain provisions with respect to exculpation and indemnification that are at
least as favorable to the Indemnified Parties as those contained in the
Certificate of Incorporation and Bylaws of the Company, as in effect on the date
hereof, and the exculpation and indemnification provisions of the equivalent
organizational

                                      -43-
<PAGE>   45

documents of each subsidiary of the Company as in effect on the date hereof
shall remain in full force and effect, and no such provisions shall be amended,
repealed or otherwise modified for a period of six (6) years following the
Effective Time in any manner that would adversely affect the rights thereunder
of individuals who, immediately prior to the Effective Time, were directors,
officers, employees or agents of the Company or any subsidiary of the Company,
unless such modification is required by applicable law.

            (b) For a period of four (4) years following the Effective Time,
Parent shall maintain in effect a policy of directors' and officers' insurance
covering those persons who are currently covered, or will be covered on or prior
to the Effective Time, by the Company's directors' and officers' insurance
policy in effect as of the date hereof (a copy of which has been heretofore
delivered to Parent) for actions or omissions occurring on or prior to the
Effective Time, which insurance policy shall contain terms and conditions
(including, without limitation, coverage amounts and scope) that are at least as
favorable in the aggregate as the terms and conditions of the Company's
directors' and officers' insurance policy in effect as of the date hereof;
provided, however, that notwithstanding the foregoing, Parent shall not be
required to pay an annual premium on such insurance policy that is greater than
one hundred and fifty percent (150%) of the annual premium payable under the
Company's directors' and officers' insurance policy in effect as of the date
hereof as set forth in Section 5.11 of the Company Disclosure Letter (the
"Current Premium"), and if the annual premium for such coverage would at any
time exceed one hundred and fifty percent (150%) of the Current Premium, the
Surviving Corporation shall maintain insurance policies which provide the
maximum and best coverage then available at an annual premium equal to one
hundred and fifty percent (150%) of the Current Premium; and provided further,
however, that notwithstanding the foregoing, Parent may satisfy its obligations
under this Section 5.11(b) by purchasing a "tail" policy under the Company's
existing directors' and officers' insurance policy which (i) has an effective
term of four (4) years from the Effective Time, (ii) covers those persons who
are currently covered, or will be covered on or prior to the Effective Time, by
the Company's directors' and officers' insurance policy in effect as of the date
hereof for actions and omissions occurring on or prior to the Effective Time,
and (iii) contains terms and conditions (including, without limitation, coverage
amounts) that are at least as favorable in the aggregate as the terms and
conditions of the Company's directors' and officers' insurance policy in effect
as of the date hereof.

            (c) Parent and the Surviving Corporation jointly and severally agree
to pay all expenses, including reasonable attorneys' fees, that may be incurred
by any Indemnified Party in enforcing the indemnity and other obligations
provided for in this Section 5.11 to the extent that such Indemnified Party is
determined to be entitled to indemnification under this Section 5.11.

            (d) The provisions of this Section 5.11 shall operate for the
benefit of, and shall be enforceable by, each of the Indemnified Parties, and
their heirs, representatives, successors and assigns.

        5.12 Nasdaq Listing. Parent shall use its commercially reasonable best
efforts to cause the shares of Parent Common Stock issuable, and those required
to be reserved for issuance, in connection with the Merger, to be authorized for
listing on Nasdaq, at or prior to the Closing Date, upon official notice of
issuance.


                                      -44-

        5.13 Company Affiliates. Section 5.13 of the Company Disclosure Letter
contains a complete and accurate list of those persons who may be deemed to be,
in the Company's reasonable judgment, affiliates of the Company within the
meaning of Rule 145 promulgated under the Securities Act (each a "Company
Affiliate"). The Company shall provide Parent with such information and
documents as Parent reasonably requests for purposes of reviewing and verifying
such list. The Company shall use its commercially reasonable efforts to deliver
or cause to be delivered to Parent, as promptly as practicable on or following
the date hereof, from each Company Affiliate who has not delivered an Affiliate
Agreement on or prior to the date hereof, an executed Affiliate Agreement. The
Affiliate Agreements will be in full force and effect as of the Effective Time.
Parent will be entitled to place appropriate legends on the certificates
evidencing any Parent Common Stock to be received by a Company Affiliate
pursuant to the terms of this Agreement, and to issue appropriate stop transfer
instructions to the transfer agent for Parent Common Stock, consistent with the
terms of each Affiliate Agreement.

        5.14 Regulatory Filings; Reasonable Efforts. As soon as may be
reasonably practicable, the Company and Parent each shall file with the United
States Federal Trade Commission (the "FTC") and the Antitrust Division of the
United States Department of Justice ("DOJ") Notification and Report Forms
relating to the transactions contemplated hereby as required by the HSR Act, as
well as comparable pre-merger notification forms required by the merger
notification or control laws and regulations of any applicable jurisdiction, as
agreed to by the parties hereto. The Company and Parent each shall promptly (i)
supply the other with any information which may be required in order to
effectuate such filings, and (ii) supply any additional information which
reasonably may be required by the FTC, the DOJ or the competition or merger
control authorities of any other jurisdiction and which the parties hereto may
reasonably deem appropriate; provided, however, that Parent shall not be
required to agree to any divestiture by Parent or the Company or any of Parent's
subsidiaries or affiliates of shares of capital stock or of any business, assets
or property of Parent, the Company or any Parent's subsidiaries or affiliates,
or the imposition of any material limitations on the ability of any of the
foregoing to conduct their respective businesses or to own or exercise control
of such assets, properties and capital stock.

        5.15 Company 401(k) Plan. The Company shall terminate, or cause to be
terminated, its 401(k) plan and any other 401(k) plan (including, without
limitation, the Chili!Soft 401(k) plan) sponsored by the Company or any
Affiliate, effective no later than the day immediately preceding the Closing
Date.

            (b) Registration Statement Effective; Proxy Statement/Prospectus.
The SEC shall have declared or ordered the Registration Statement to be
effective, no stop order suspending the effectiveness of the Registration
Statement or any part thereof shall have been issued, and no proceeding for that
purpose, and no similar proceeding in respect of the Proxy Statement/Prospectus,
shall have been initiated or threatened in writing (and not abandoned or
withdrawn) by the SEC.

            (c) No Order; HSR Act. No Governmental Entity shall have enacted,
issued, promulgated, enforced or entered any statute, rule, regulation,

the Merger illegal or otherwise prohibiting consummation of the Merger. All
waiting periods, if any, under the HSR Act relating to the transactions
contemplated hereby will have expired or terminated early and all material
foreign antitrust approvals required to be obtained prior to the Merger in
connection with the transactions contemplated hereby shall have been obtained.

            (d) Tax Opinions. Parent and the Company shall each have received
written opinions from their respective tax counsel (Wilson Sonsini Goodrich &
Rosati, Professional Corporation, and Brobeck Phleger & Harrison LLP,
respectively), in form and substance reasonably satisfactory to them, to the
effect that the Merger will constitute a reorganization within the meaning of
Section 368(a) of the Code, and such opinions shall not have been withdrawn;
provided, however, that if the counsel to either Parent or the Company shall not
render such opinion, this condition shall nonetheless be deemed to be satisfied
with respect to such party if counsel to the other party hereto shall render
such opinion to such party. The parties hereto agree to make such reasonable
representations as requested by such counsel for the purpose of rendering such
opinions.

            (e) Nasdaq Listing. The shares of Parent Common Stock issuable to
the stockholders of the Company in connection with the Merger pursuant to this
Agreement, and such other shares required to be reserved for issuance in
connection with the Merger, shall have been authorized for listing on the
Nasdaq, upon official notice of issuance, or shall be exempt from such
requirement under then applicable laws, regulations and rules of The Nasdaq
Stock Market, Inc.

        6.2 Additional Conditions to Obligations of the Company. The obligation
of the Company to consummate and effect the Merger shall be subject to the
satisfaction or fulfillment, at or prior to the Closing Date, of each of the

clauses (i) and (ii), (A) in each case, or in the aggregate, as does not
constitute a Material Adverse Effect on Parent, (B) for changes contemplated by
this Agreement, and (C) for those representations and warranties which address
matters only as of a particular date (which

                                      -46-
<PAGE>   48

representations shall have been true and correct (subject to the Material
Adverse Effect qualifications as set forth in the preceding clause (A)) as of
such particular date) (it being understood that, for purposes of determining the
accuracy of such representations and warranties, all "Material Adverse Effect"
qualifications and other qualifications based on the word "material" or similar
phrases contained in such representations and warranties shall be disregarded).
The Company shall have received a certificate with respect to the foregoing
signed on behalf of Parent by duly authorized officer thereof.

            (b) Agreements and Covenants. Parent and Merger Sub shall in all
material respects have performed or complied with all agreements and covenants
required by this Agreement to be performed or complied with by them on or prior
to the Closing Date, and the Company shall have received a certificate to such
effect signed on behalf of Parent by a duly authorized officer thereof.

force and effect as if made on and as of the Closing Date, except, with respect
to clauses (i) and (ii), (A) in each case, or in the aggregate, as does not
constitute a Material Adverse Effect on the Company; provided, however, that
such Material Adverse Effect qualifier shall be inapplicable with respect to
representations and warranties contained in Sections 2.3(a) (other than an
inaccuracy in the aggregate amount of no greater than 50,000 shares of Company
Common Stock and shares of Company Common Stock issuable upon exercise of
Company Stock Options), 2.3(c), 2.4, 2.18, 2.22, 2.23, 2.24 and 2.25, each of
which individually shall have been true and correct in all respects as of the
date of this Agreement and shall be true and correct in all material respects on
and as of the Closing Date, and provided, further, that such Material Adverse
Effect qualifier shall be inapplicable with respect to representations and
warranties contained in Section 2.19, which individually shall have been true
and correct in all material respects as of the date of this Agreement and shall
be true and correct in all material respects on and as of the Closing Date, (B)
for changes contemplated by this Agreement, and (C) for those representations
and warranties which address matters only as of a particular date (which

determining the accuracy of such representations and warranties, (x) all
"Material Adverse Effect" and materiality qualifications and other
qualifications based on the word "material" or similar phrases contained in such
representations and warranties shall be disregarded, and (y) any update of or
modification to the Company Disclosure Letter made or purported to have been
made after the date of this Agreement shall be disregarded). Parent shall have
received a certificate with respect to the foregoing signed on behalf of Company
by a duly authorized officer thereof.


                                      -47-
<PAGE>   49

            (b) Agreements and Covenants. The Company shall in all material
respects have performed or complied with all agreements and covenants required
by this Agreement to be performed or complied with by it at or prior to the
Closing Date, and Parent shall have received a certificate to such effect signed
on behalf of Company by a duly authorized officer thereof.

            (c) Non-Competition Agreements. Each of the employees who have
executed a Non-Competition Agreement shall continue to be employed by the
Company as of the Closing, shall not have notified (whether formally or
informally) Parent or the Company of such employee's intention of leaving the

                                   ARTICLE VII
                        TERMINATION, AMENDMENT AND WAIVER

        7.1 Termination. This Agreement may be terminated at any time prior to
the Effective Time, whether before or after the requisite approval of the
stockholders of the Company has been obtained in respect of this Agreement and
the Merger:

            (a) by mutual written consent of Parent and the Company, duly
authorized by the respective Boards of Directors of Parent and the Company;

            (b) by either Parent or the Company if the Merger shall not have
been consummated by March 16, 2001 for any reason; provided, however, that the
right to terminate this Agreement under this Section 7.1(b) shall not be
available to any party whose action or failure to act has been a principal cause
of or resulted in the failure of the Merger to occur on or before such date, and
such action or failure to act constitutes a breach of this Agreement;

            (c) by either Parent or the Company if a Governmental Entity shall
have issued an order, decree or ruling or taken any other action, in any case
having the effect of permanently restraining, permanently enjoining or otherwise
permanently prohibiting the Merger, which order, decree, ruling or other action
is final and nonappealable and remains in effect at the time of termination;

            (d) by either Parent or the Company if the requisite approval of the
stockholders of the Company contemplated by this Agreement shall not have been
obtained by reason of the failure to obtain the requisite vote at a meeting of
the stockholders of the Company, duly convened therefor or at any adjournment or
postponement thereof; provided, however, that the right to terminate this
Agreement under this Section 7.1(d) shall not be available to a party in

                                      -48-
<PAGE>   50

the event that the failure to obtain the requisite approval of the stockholders
of the Company shall have been caused by the action or failure to act of such
party proposing to exercise its right of termination under this Section 7.1(d),
and such action or failure to act constitutes a breach of this Agreement;

            (e) by Parent if a Triggering Event (as defined below) shall have
occurred;

            (f) by the Company, upon a breach of any representation, warranty,
covenant or agreement on the part of Parent set forth in this Agreement, or if
any representation or warranty of Parent shall have become untrue, in either
case such that the conditions set forth in Section 6.2(a) or Section 6.2(b)
hereof would not be satisfied as of the time of such breach or as of the time
such representation or warranty shall have become untrue; provided, however,
that if such inaccuracy in Parent's representations and warranties or breach by
Parent is curable by Parent through the exercise of its commercially reasonable
efforts, then the Company may not terminate this Agreement under this Section
7.1(f) for thirty (30) calendar days following the delivery of written notice
from the Company to Parent of such breach, provided Parent continues to exercise
commercially reasonable efforts to cure such breach (it being understood and
agreed that the Company may not terminate this Agreement pursuant to this
Section 7.1(f) if the Company shall have materially breached this Agreement or
if such breach by Parent is cured during such thirty (30) calendar day period);

            (g) by Parent, upon a breach of any representation, warranty,
covenant or agreement on the part of the Company set forth in this Agreement, or
if any representation or warranty of Company shall have become untrue, in either
case such that the conditions set forth in Section 6.3(a) or Section 6.3(b)
hereof would not be satisfied as of the time of such breach or as of the time
such representation or warranty shall have become untrue; provided, however,
that if such inaccuracy in the Company's representations and warranties or
breach by the Company is curable by the Company through the exercise of its
commercially reasonable efforts, then Parent may not terminate this Agreement
under this Section 7.1(g) for thirty (30) calendar days following the delivery
of written notice from Parent to the Company of such breach, provided the
Company continues to exercise commercially reasonable efforts to cure such
breach (it being understood and agreed that Parent may not terminate this
Agreement pursuant to this Section 7.1(g) if Parent shall have materially
breached this Agreement or if such breach by the Company is cured during such
thirty (30) calendar day period);

            (h) by Parent, if there has been a Material Adverse Effect with
respect to the Company and its subsidiaries that is not curable by the Company
through the exercise of its commercially reasonable efforts; or

            (i) by Company, if there has been a Material Adverse Effect with
respect to Parent that is not curable by Parent through the exercise of its
commercially reasonable efforts.

For the purposes of this Agreement, a "Triggering Event" shall be deemed to have
occurred if: (i) the Board of Directors of the Company or any committee thereof
shall for any reason have withdrawn or shall have amended or modified, in either
case, in a manner adverse to Parent its unanimous recommendation in favor of the
adoption and approval of the Agreement or the

                                      -49-
<PAGE>   51

approval of the Merger; (ii) the Company shall have failed to include in the
Proxy Statement/Prospectus the unanimous recommendation of the Board of
Directors of the Company in favor of the adoption and approval of the Agreement
and the approval of the Merger; (iii) the Board of Directors of the Company
shall have failed to reaffirm its unanimous recommendation in favor of the
adoption and approval of the Agreement and the approval of the Merger within ten
(10) business days after Parent requests in writing that such recommendation be
reaffirmed at any time following the announcement of an Acquisition Proposal;
(iv) the Board of Directors of the Company or any committee thereof shall have
approved or recommended any Acquisition Proposal; (v) the Company shall have
entered into any letter of intent or similar document or any agreement, contract
or commitment accepting any Acquisition Proposal; (vi) the Company shall have
breached any of the terms of Section 5.5 hereof; or (vii) a tender or exchange
offer relating to not less than fifteen percent (15%) of the then-outstanding
shares of capital stock of the Company shall have been commenced by a person
unaffiliated with Parent and the Company shall not have sent to its
securityholders pursuant to Rule 14e-2 promulgated under the Securities Act,
within ten (10) business days after such tender or exchange offer is first
commenced, a statement indicating that the Company recommends rejection of such
tender or exchange offer.

        7.2 Notice of Termination; Effect of Termination. Any termination of
this Agreement pursuant to Section 7.1 hereof shall be effective immediately
upon the delivery of written notice of the terminating party to the other party
or parties hereto. In the event of the termination of this Agreement pursuant to
Section 7.1 hereof, this Agreement shall be of no further force or effect,
except (i) as set forth in this Section 7.2, and as set forth in Section 7.3 and
Article VIII (miscellaneous) hereof, each of which shall survive the termination
of this Agreement, and (ii) nothing herein shall relieve any party hereto from
any liability for any willful or intentional breach of this Agreement. No
termination of this Agreement shall affect the obligations of the parties hereto
contained in the Confidentiality Agreement, all of which obligations shall
survive termination of this Agreement in accordance with their terms.

        7.3 Fees and Expenses.

            (a) General. Except as otherwise provided in this Section 7.3, all
fees and expenses incurred in connection with this Agreement and the
transactions contemplated hereby shall be paid by the party incurring such fees
and expenses, whether or not the Merger is consummated; provided, however, that
Parent and the Company shall share equally all fees and expenses, other than
attorneys' and accountants fees and expenses, incurred in relation to the
printing and filing (with the SEC) of the Proxy Statement/Prospectus (including
any preliminary materials related thereto) and the Registration Statement
(including financial statements and exhibits) and any amendments or supplements
thereto, and any fees required to be paid under the HSR Act.

            (b) Company Payments.

                (i) Notwithstanding anything to the contrary set forth in this
Agreement, in the event that this Agreement is terminated by Parent pursuant to
Section 7.1(e) hereof, the Company shall pay to Parent in immediately available
funds, within one (1) business day after demand by Parent, an amount in cash
equal to $59,000,000 (the "Termination Fee").

                                      -50-
<PAGE>   52

                (ii) Notwithstanding anything to contrary set forth in this
Agreement, in the event that (A) this Agreement is terminated by Parent or the
Company, as applicable, pursuant to Section 7.1(b) or Section 7.1(d) hereof, (B)
following the date hereof and prior to the termination of this Agreement, a
third party shall have announced an Acquisition Proposal, and (C) within twelve
(12) months following the termination of this Agreement, a Company Acquisition
(as defined in Section 7.3(b)(iv) hereof) is consummated or the Company enters
into an agreement or letter of intent providing for a Company Acquisition, or a
third party commences a tender or exchange offer for a Company Acquisition, then
the Company shall pay to Parent, in immediately available funds, an amount in
cash equal to the Termination Fee upon (x) the consummation of such Company
Acquisition, or (y) the entry by the Company into such agreement or letter of
intent.

                (iii) The Company acknowledges that the agreements set forth in
this Section 7.3(b) are an integral part of the transactions contemplated by
this Agreement, and that, without these agreements, Parent would not enter into
this Agreement. Accordingly, if the Company shall fail to pay in a timely manner
the amounts due pursuant to this Section 7.3(b), and, in order to obtain such
payment, Parent makes a claim that results in a final judgment against the
Company for the amounts set forth in this Section 7.3(b), the Company shall pay
to Parent its reasonable costs and expenses (including reasonable attorneys'
fees and expenses) in connection with such suit, together with interest on the
amounts set forth in this Section 7.3(b) at the prime rate of The Chase
Manhattan Bank in effect on the date such payment was required to be made.
Payment of the fees described in this Section 7.3(b) shall not be in lieu of
damages incurred in the event of any willful or intentional breach of this
Agreement.

                (iv) For all purposes of and under this Agreement, the term
"Company Acquisition" shall mean any of the following transactions (other than
the transactions contemplated by this Agreement); (i) a merger, consolidation,
business combination, recapitalization, liquidation, dissolution or similar
transaction involving the Company pursuant to which the stockholders of the
Company immediately preceding such transaction hold less than fifty percent
(50%) of the aggregate equity interests in the surviving or resulting entity of
such transaction, (ii) a sale or other disposition by the Company of assets
representing in excess of fifty percent (50%) of the aggregate fair market value
of the Company's business immediately prior to such sale, or (iii) the
acquisition by any person or group (including by way of a tender offer or an
exchange offer or issuance by the Company), directly or indirectly, of
beneficial ownership or a right to acquire beneficial ownership of shares
representing in excess of fifty percent (50%) of the voting power of the then
outstanding shares of capital stock of the Company.

        7.4 Amendment. Subject to applicable law, this Agreement may be amended
by the parties hereto at any time, but only by execution of an instrument in
writing, signed on behalf of each of the parties hereto by a duly authorized
officer thereof.

        7.5 Extension; Waiver. At any time prior to the Effective Time, any
party hereto may, to the extent legally allowed, (i) extend the time for the
performance of any of the obligations or other acts of the other parties hereto,
(ii) waive any inaccuracies in the representations and warranties made to such
party contained herein or in any document delivered pursuant hereto,

                                      -51-
<PAGE>   53

and (iii) 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 valid only if set forth in an
instrument in writing signed on behalf of such party. Any delay in exercising
any right under this Agreement shall not constitute a waiver of such right.

                                  ARTICLE VIII

            (a) When a reference is made in this Agreement to Exhibits, such
reference shall be to an Exhibit to this Agreement unless otherwise indicated.
When a reference is made in this Agreement to Sections, such reference shall be
to a Section of this Agreement. Unless otherwise indicated the words "include,"
"includes" and "including" when used herein shall be deemed in each case to be
followed by the words "without limitation." The table of contents and headings
contained in this Agreement are for reference purposes only and shall not affect
in any way the meaning or interpretation of this Agreement. When reference is
made herein to "the business of" an entity, such reference shall be deemed to
include the business of all direct and indirect subsidiaries of such entity
taken together with such entity as a whole. Reference to the subsidiaries of an
entity (the "Parent Entity") shall be deemed to include all direct and indirect
subsidiaries of such Parent Entity, but shall not include any entity of which
less than twenty percent (20%) of the outstanding voting securities or other
equity interests are owned by the Parent Entity.

            (b) For purposes of this Agreement the term "knowledge" means with
respect to a party hereto, with respect to any matter in question, that any of

            (c) For purposes of this Agreement, the term "Material Adverse
Effect" when used in connection with an entity means any change, event,
violation, inaccuracy, circumstance or effect that is materially adverse to the
business, assets (including intangible assets), capitalization, financial
condition or results of operations of such entity and its subsidiaries taken as
a whole. For purposes of this Agreement, the term "person" shall mean any
individual, corporation (including any non-profit corporation), general
partnership, limited partnership, limited liability partnership, joint venture,
estate, trust, company (including any limited liability company or joint stock
company), firm or other enterprise, association, organization, entity or
Governmental Entity; provided, however, that in no event shall any of the
following, alone or in combination, be deemed to constitute, nor shall any of
the following be taken into account in determining whether there has been or
will be a Material Adverse Effect on any entity: (i) any change in such entity's
stock price or trading volume in and of itself; or (ii) any change, event,
violation, inaccuracy, circumstance or effect that such entity successfully
bears the burden of proving results from changes affecting any of the industries
in which such entity operates generally or the United States economy generally
(which changes in each case do not disproportionately affect such entity); or
(iii) any change, event, violation, inaccuracy, circumstance or effect resulting
from the disruption or loss of existing or prospective customer, distributor or
supplier relationships that such entity successfully bears the burden of proving
results from the public announcement or pendency of the transactions
contemplated hereby.

        8.4 Counterparts. This Agreement may be executed in one or more
counterparts, all of which shall be considered one and the same agreement and
shall become effective when one or more counterparts have been signed by each of
the parties and delivered to the other party, it being understood that all
parties need not sign the same counterpart.

        8.5 Entire Agreement; Third Party Beneficiaries. This Agreement and the
documents and instruments and other agreements among the parties hereto as
contemplated by or referred to herein, including the Company Disclosure Letter
(i) constitute the entire agreement among the parties with respect to the
subject matter hereof and supersede all prior agreements and understandings,
both written and oral, among the parties with respect to the subject matter
hereof, it being understood that the Confidentiality Agreement shall continue in
full force and effect until the Closing and shall survive any termination of
this Agreement; and (ii) are not intended to confer upon any other person any
rights or remedies hereunder, except as specifically provided in Section 5.11
hereof.

        8.6 Severability. In the event that any provision of this Agreement or
the application thereof, becomes or is declared by a court of competent
jurisdiction to be illegal, void or unenforceable, the remainder of this
Agreement will continue in full force and effect and the application of such
provision to other persons or circumstances will be interpreted so as reasonably
to effect the intent of the parties hereto. The parties further agree to replace
such void or unenforceable provision of this Agreement with a valid and
enforceable provision that will

achieve, to the extent possible, the economic, business and other purposes of
such void or unenforceable provision.

        8.7 Other Remedies; Specific Performance. Except as otherwise provided
herein, any and all remedies herein expressly conferred upon a party will be
deemed cumulative with and not exclusive of any other remedy conferred hereby,
or by law or equity upon such party, and the exercise by a party of any one
remedy will not preclude the exercise of any other remedy. The parties hereto
agree that irreparable damage would occur in the event that any of the
provisions of this Agreement were not performed in accordance with their
specific terms or were otherwise breached. It is accordingly agreed that the
parties shall be entitled to seek an injunction or injunctions to prevent
breaches of this Agreement and to enforce specifically the terms and provisions
hereof in any court of the United States or any state having jurisdiction, this
being in addition to any other remedy to which they are entitled at law or in
equity.

        8.8 Governing Law. This Agreement shall be governed by and construed in
accordance with the laws of the State of Delaware, regardless of the laws that
might otherwise govern under applicable principles of conflicts of law thereof.

        8.9 Rules of Construction. The parties hereto agree that they have been
represented by counsel during the negotiation and execution of this Agreement
and, therefore, waive the application of any law, regulation, holding or rule of
construction providing that ambiguities in an agreement or other document will
be construed against the party drafting such agreement or document.

        8.10 Assignment. No party may assign either this Agreement or any of its
rights, interests, or obligations hereunder without the prior written approval
of the other parties. Subject to the preceding sentence, this Agreement shall be
binding upon and shall inure to the benefit of the parties hereto and their
respective successors and permitted assigns.
