                          AGREEMENT AND PLAN OF MERGER

         THIS AGREEMENT AND PLAN OF MERGER (this "AGREEMENT"), is entered into
as of December 22, 2002 by and among Yahoo! Inc., a Delaware corporation
("PARENT"), December  2002  Acquisition Corp., a Delaware corporation and a
direct, wholly-owned subsidiary of Parent ("MERGER SUB"), and Inktomi
Corporation, a Delaware corporation (the "COMPANY").

                                    RECITALS

         A.       The Board of Directors of each of Parent, Merger Sub and the
Company has approved, and deems it advisable and in the best interests of its
respective stockholders to consummate the acquisition of the Company by Parent
upon the terms and subject to the conditions set forth herein.

         B.       The Board of Directors of each of Parent, Merger Sub and the
Company has unanimously (in the case of Parent, with one director abstaining)
approved this Agreement and the transactions contemplated hereby, including the
Merger (as defined in Section 1.1), in accordance with the Delaware General
Corporation Law ("DGCL") and upon the terms and subject to the conditions set
forth herein.

         C.       The Board of Directors of the Company (the "COMPANY BOARD OF
DIRECTORS") has resolved to recommend to its stockholders approval and adoption
of this Agreement and approval of the Merger and the transactions contemplated
hereby.

         D.       Parent, as the sole stockholder of Merger Sub, has approved
and adopted this Agreement and approved the Merger.

         E.       Concurrently with the execution and delivery of this
Agreement, and as a condition and inducement to Parent's and Merger Sub's
willingness to enter into this Agreement, certain stockholders of the Company
are entering into Voting Agreements in the form attached hereto as Exhibit A

         F.       Parent, Merger Sub and the Company desire to make certain
representations, warranties, covenants and agreements in connection with the

         1.1      The Merger.  At the Effective Time (as defined in Section
1.2) and subject to and upon the terms and conditions of this Agreement and the
applicable provisions of the DGCL, Merger Sub shall be merged with and into the

         1.2      Effective Time; Closing. Subject to the provisions of this
Agreement, the parties hereto shall cause the Merger to be consummated by filing
a Certificate of Merger with the Secretary of State of the State of Delaware in

MERGER") (the time of such filing with the Secretary of State of the State of
Delaware (or such later time as may be agreed upon in writing by the Company and
Parent and specified in the Certificate of Merger) being the "EFFECTIVE TIME")
as soon as practicable on or after the Closing Date (as defined below). The
closing of the Merger (the "CLOSING") shall take place at the offices of Davis
Polk & Wardwell, located at 1600 El Camino Real, Menlo Park, California, at a
time and date to be specified by the parties, which shall be no later than the
second business day after the satisfaction or waiver of the conditions set forth
in Article VI (other than those conditions that by their nature are to be
satisfied at the Closing, but subject to the satisfaction or waiver of those
conditions), or at such other time, date and location as the parties hereto
agree in writing (the "CLOSING DATE").

         1.3      Effect of the Merger. At the Effective Time, the effect of the
Merger shall be as provided in this Agreement and the applicable provisions of
the DGCL.

         1.4      Certificate of Incorporation and Bylaws. The certificate of
incorporation of the Company, as in effect immediately prior to the Effective
Time, shall be the certificate of incorporation of the Surviving Corporation
until thereafter amended as provided therein or by the DGCL; provided that, at
the Effective Time, such certificate of incorporation shall be amended as set
forth in Exhibit B. The bylaws of Merger Sub, as in effect immediately prior to
the Effective Time, shall be the bylaws of the Surviving Corporation until
thereafter amended as provided therein or by the DGCL.

         1.5      Directors and Officers. The initial directors of the Surviving
Corporation shall be the directors of Merger Sub immediately prior to the
Effective Time, until their respective successors are duly elected or appointed
and qualified. The initial officers of the Surviving Corporation shall be the
officers of Merger Sub immediately prior to the Effective Time, until their
respective successors are duly appointed.

         1.6      Effect on Capital Stock. Subject to the terms and conditions
of this Agreement, at the Effective Time, by virtue of the Merger and without
any action on the part of Parent, Merger Sub, the Company or the holders of any
shares of capital stock of the Company, the following shall occur:

                  (a)      Company Common Stock. Each share of the common stock,

preferred stock purchase rights (the "COMPANY RIGHTS") under the Preferred Stock
Rights Agreement, dated as of August 10, 2000, between the Company and Wells
Fargo Shareowner Services, as Rights Agent thereunder (the "COMPANY RIGHTS
AGREEMENT"), "COMPANY COMMON STOCK") issued and outstanding immediately prior to
the Effective Time (the "SHARES"), other than any shares of Company Common Stock
to be canceled pursuant to Section 1.6(c) and, other than as provided in Section
1.8 with respect to Shares as to which appraisal rights have been perfected,
will be

                                       2
<PAGE>
canceled and extinguished and automatically converted into the right to receive
$1.65 in cash (the "MERGER CONSIDERATION") upon surrender of the certificate
representing such share of Company Common Stock in the manner provided in
Section 1.7 (or in the case of a lost, stolen or destroyed certificate, upon
delivery of an affidavit (and bond, if required) in the manner provided in
Section 1.10).

                  (b)      Repurchase Rights. If any shares of Company Common
Stock outstanding immediately prior to the Effective Time are unvested or are
subject to a repurchase option, risk of forfeiture or other condition under any
applicable restricted stock purchase agreement or other agreement with the
Company, then, at Parent's option and in Parent's sole discretion, the Merger
Consideration in respect of such shares shall either be (i) paid to the holder
thereof, in the manner provided in Section 1.7, without restriction or (ii) paid
to the holder thereof over time upon satisfaction of the vesting requirements
associated with the applicable restricted stock schedule.

                  (c)      Treasury and Parent Owned Stock. Each share of
Company Common Stock held by the Company or Parent or any direct or indirect
wholly-owned subsidiary of Parent immediately prior to the Effective Time shall
be canceled and extinguished without any conversion thereof. Each share of
Company Common Stock held by any direct or indirect subsidiary of the Company
immediately prior to the Effective Time shall remain outstanding.

                  (d)      Capital Stock of Merger Sub. Each share of common
stock, par value $0.001 per share, of Merger Sub (the "MERGER SUB COMMON STOCK")
issued and outstanding immediately prior to the Effective Time shall be
converted into one validly issued, fully paid and nonassessable share of common
stock, par value $0.001 per share, of the Surviving Corporation.

                  (e)      Stock Options. At the Effective Time, all Company
Options outstanding under each Company Option Plan shall be assumed by Parent in
accordance with Section 5.7(a).

                  (f)      Adjustments to Merger Consideration. The Merger
Consideration shall be adjusted to reflect fully the appropriate effect of any
stock split, reverse stock split, stock dividend (including any dividend or
distribution of securities convertible into Company Common Stock),
reorganization, recapitalization, reclassification or other like change with
respect to Company Common Stock having a record date on or after the date hereof
and prior to the Effective Time.

         1.7      Surrender of Certificates.

                  (a)      Paying Agent. Parent shall designate a bank or trust
company reasonably satisfactory to the Company to act as the paying agent (the
"PAYING AGENT") in the Merger.

                  (b)      Parent to Provide Merger Consideration. At or before
the Effective Time, Parent shall enter into an agreement with the Paying Agent,
reasonably satisfactory to the Company, which shall provide that Parent shall
make available to the Paying Agent for payment in accordance with this Article
I, and Parent shall deposit or cause to be deposited with the Paying Agent the
cash payable pursuant to Section 1.6(a) in exchange for outstanding shares of
Company Common Stock. Any cash deposited with the Paying Agent shall hereinafter

<PAGE>
                  (c)      Exchange Procedures. Promptly after the Effective
Time, Parent shall cause the Paying Agent to mail to each holder of record (as
of the Effective Time) of a certificate or certificates (the "CERTIFICATES")
which immediately prior to the Effective Time represented outstanding shares of
Company Common Stock whose shares were converted into the right to receive the
Merger Consideration pursuant to Section 1.6(a), (i) a letter of transmittal
(which shall specify that delivery shall be effected, and risk of loss and title
to the Certificates shall pass, only upon delivery of the Certificates to the
Paying Agent and shall be in such form and have such other provisions as Parent
may reasonably specify) and (ii) instructions for use in effecting the surrender
of the Certificates in exchange for payment of the Merger Consideration. Upon
surrender of Certificates for cancellation to the Paying Agent or to such other
agent or agents as may be appointed by Parent, together with such letter of
transmittal, duly completed and validly executed in accordance with the
instructions thereto and such other documents as may reasonably be required by
the Paying Agent, the holder of such Certificates shall be entitled to receive
in exchange therefor the Merger Consideration (after taking into account all
Certificates surrendered by such holder) to which such holder is entitled
pursuant to Section 1.6(a), and the Certificates so surrendered shall forthwith
be canceled except as set forth in Section 1.8. Until so surrendered,
outstanding Certificates will be deemed from and after the Effective Time, for
all corporate purposes, to evidence the ownership of the right to receive the
Merger Consideration attributable to such.

                  (d)      Transfers of Ownership. If any portion of the Merger
Consideration is to be paid to a Person other than the Person in whose name the
surrendered Certificates are registered, it will be a condition of payment
thereof that the Certificates so surrendered will be properly endorsed and
otherwise in proper form for transfer and that the persons requesting such
payment will have paid to Parent or any agent designated by it any transfer or
other Taxes (as defined in Section 2.7) required by reason of the payment of the
Merger Consideration 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.

                  (e)      Required Withholding. Each of the Paying Agent 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 Internal Revenue Code of 1986, as
amended (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, the amount of such consideration shall be treated for
all purposes under this Agreement as having been paid to the person to whom such
consideration would otherwise have been paid.

                  (f)      No Liability. Notwithstanding anything to the
contrary in this Section 1.7, none of the Paying Agent, the Surviving
Corporation or any party hereto shall be liable to a holder of shares of Company
Common Stock for any amount properly paid to a public official pursuant to any
applicable abandoned property, escheat or similar law.

                  (g)      Investment of Paying Fund. The Paying Agent shall
invest the Merger Fund as directed by Parent on a daily basis; provided that no
such investment or loss thereon shall affect the amounts payable or the timing
of payments to Company stockholders pursuant to

                                       4
<PAGE>
this Article I. Any interest and other income resulting from such investment
shall become a part of the Merger Fund, and any amounts in excess of the amounts
payable to Company stockholders pursuant to this Article I shall promptly be
paid to Parent.

                  (h)      Termination of Merger Fund. Any portion of the Merger
Fund which remains undistributed to the holders of Certificates six (6) months
after the Effective Time shall, at the request on the instruction of the
Surviving Corporation, be delivered to the Surviving Corporation, and any
holders of the Certificates who have not surrendered such Certificates in
compliance with this Section 1.7 shall after such delivery to the Surviving
Corporation look only to the Surviving Corporation for payment of the Merger
Consideration pursuant to Section 1.6(a). Any such portion of the Merger Fund
remaining unclaimed by holders of shares of Company Common Stock immediately
prior to such time as such amounts would otherwise escheat to or become property
of any Governmental Entity shall, to the extent permitted by law, become the
property of Parent free and clear of any claims or interest of any person
previously entitled thereto.

         1.8      Dissenting Shares. Notwithstanding Section 1.6, Shares
outstanding immediately prior to the Effective Time and held by a holder who has
not voted in favor of the Merger or consented thereto in writing and who has
demanded appraisal for such Shares in accordance with the DGCL ("DISSENTING
SHARES") shall not be converted into a right to receive the Merger
Consideration, unless such holder fails to perfect or withdraws or otherwise
loses its rights to appraisal or it is determined that such holder does not have
appraisal rights in accordance with the DGCL. If after the Effective Time such
holder fails to perfect or withdraws or loses its right to appraisal, or if it
is determined that such holder does not have an appraisal right, such Shares
shall be treated as if they had been converted as of the Effective Time into the
right to receive in exchange for each Share the Merger Consideration. The
Company shall give Parent and Merger Sub prompt notice of any demands received
by the Company for appraisal of Shares, and Parent and Merger Sub shall have the
right to participate in all negotiations and proceedings with respect to such
demands except as required by applicable law. The Company shall not, except with
prior written consent of Parent and Merger Sub, make any payment with respect
to, or settle or offer to settle, any such demands.

         1.9      No Further Ownership Rights in Company Common Stock. All cash
paid upon the surrender for payment of shares of Company Common Stock in
accordance with the terms 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, after 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.

         1.10     Lost, Stolen or Destroyed Certificates. If any Certificate
shall have been lost, stolen or destroyed, upon the making of an affidavit 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 Paying Agent shall pay, in exchange for such lost,
stolen or destroyed Certificate,

                                       5
<PAGE>
the Merger Consideration to be paid in respect of the Shares represented by such
Certificate, as contemplated by this Article I.

         1.11     Further Action. At and after the Effective Time, the officers
and directors of Parent and the Surviving Corporation will be authorized to
execute and deliver, in the name and on behalf of the Company and Merger Sub,
any deeds, bills of sale, assignments or assurances and to take and do, in the
name and on behalf of the Company and Merger Sub, any other actions and things
to vest, perfect or confirm of record or otherwise in the Surviving Corporation
any and all right, title and interest in, to and under any of the rights,
properties or assets acquired or to be acquired by the Surviving Corporation as
a result of, or in connection with, the Merger.

specific individual section of this Agreement and shall be deemed to qualify the

owned, leased or operated by it or the nature of its activities makes such
qualification or licensing necessary except, in the cases of clauses (ii) and
(iii), for those authorizations, qualifications and licenses the absence of
which would not, individually or in the aggregate, have a Material Adverse
Effect on the Company.

                  (b)      The Company has set forth in Section 2.1(b) of the
Company Disclosure Letter a true and complete list of all of the Company's

a true and correct copy of the Certificate of Incorporation and Bylaws of the
Company and similar governing instruments of each of its subsidiaries, each as

         The Company has made available to Parent an accurate and complete copy

of the Company's stockholders and the filing of the Certificate of Merger
pursuant to the DGCL. The affirmative vote of the holders of a majority of the
outstanding shares of Company Common Stock to approve and adopt this Agreement
and approve the Merger is the only vote of the holders of any class or series of
Company capital stock necessary to approve and adopt this Agreement and approve
the Merger. This Agreement has been duly executed and delivered by the Company
and, assuming the due authorization execution and delivery hereof by Parent and
Merger Sub, constitutes a valid and binding agreement of the Company,

moratorium or other similar laws, now or hereafter in effect, affecting of
creditors' rights generally, and (ii) the remedy of specific performance and
injunctive and other forms of equitable relief may be subject to equitable

Company does not, and the performance of this Agreement by the Company and the
consummation by the Company of the Merger and the other transactions
contemplated by this Agreement and compliance by the Company with the provisions
of this Agreement will not, (i) conflict with or violate the Certificate of
Incorporation or Bylaws of the Company or the equivalent organizational
documents of any of its subsidiaries, (ii) subject to compliance with the
requirements set forth in Section 2.4(d) below, conflict with or violate any
federal, state, local, municipal, foreign or other law, statute, constitution,
principle of common law, resolution, ordinance, guidance, code, order, judgment,
edict, decree, rule, regulation, ruling or requirement issued, enacted, adopted,
promulgated, implemented or otherwise put into effect by or under the authority
of any Governmental Entity ("LEGAL REQUIREMENT") applicable to the Company or
any of its subsidiaries or by which the Company or any of its subsidiaries or
any of their respective properties is bound or affected, or (iii) result in any
breach of or constitute a default (or an event that with notice or lapse of time
or both would become a default) under, or impair the Company's rights or alter
the rights or obligations of any third party under, or give to others any rights
of termination, amendment, acceleration or cancellation of, or result in the
creation of a Lien on any of the properties or assets of the Company or any of
its subsidiaries pursuant to any note, bond, mortgage, indenture, contract,
agreement, lease, license, permit, franchise, concession, or other instrument,
obligation, commitment, arrangement or understanding, to which the Company or
any of its subsidiaries is a party or by which the Company or any of its
subsidiaries or any of their respective assets are bound or affected, other
than, in the case of clauses (ii) and (iii), any such conflicts, violations,
breaches, defaults, rights, terminations, amendments, accelerations,
cancellations or Liens that individually or in the aggregate would not have a
Material Adverse Effect on the Company or prevent or materially adversely affect
the

                                       9
<PAGE>
ability of the Company to consummate the Merger within the time frame in which
the Merger would otherwise be consummated in the absence of such conflict,
violation, breach, default, right, termination, amendment, acceleration,
cancellation or Lien.

                  (c)      Section 2.4(c) of the Company Disclosure Letter lists
all consents, waivers and approvals under any of the Company's or any of its
subsidiaries' agreements, contracts, arrangements, licenses or leases, other
than contracts that are terminable at-will on no more than 30 days' notice
without liability or financial obligation, required to be obtained in connection
with the consummation of the Merger which, if individually or in the aggregate
not obtained, would be reasonably expected to result in a Material Adverse
Effect with respect to the Company, Parent or the Surviving Corporation.

                  (d)      No consent, approval, order or authorization of,
action by or in respect of, or registration, declaration or filing with any
supranational, national, state, municipal, local or foreign government, any

other governmental authority or instrumentality, or any quasi-governmental or
private body exercising any regulatory, taxing, importing or other governmental

antirust or competition laws of other jurisdictions, (iv) the consents listed on
Section 2.4(c) of the Company Disclosure Letter; (v) such consents, approvals,
orders, authorizations, registrations, declarations and filings as may be
required under applicable state securities or "blue sky" laws and the securities
laws of any foreign country, and (vi) such other consents, authorizations,
filings, approvals and registrations which if not obtained or made individually
or in the aggregate would not be material to the Company, Parent or the
Surviving Corporation or materially adversely affect the ability of the parties
hereto to consummate the Merger within the time frame in which the Merger would
otherwise be consummated in the absence of the need for such consent, approval,
order, authorization, registration, declaration or filings. The consents,
approvals, orders, authorizations, registrations, declarations and filings set
forth in (i) through (v) are referred to herein as the "NECESSARY CONSENTS."

therein or necessary in order to make the statements therein, in the light of
the circumstances under which they were made, not misleading. None of the
Company's subsidiaries is required to file any forms, reports or other documents
with the SEC or similar regulatory body.

transactions contemplated hereby; nor, to the Company's knowledge, is there any

pursuant to, any note, bond, mortgage, indenture, contract, agreement, lease,
license, permit, franchise or other instrument or obligation to which Parent or
Merger Sub is a party or by which Parent or Merger Sub or any of their
respective assets are bound or affected, other than, in the case of clauses (ii)

expression by any person of an intention to make an Acquisition Proposal or any
request for nonpublic information or inquiry which it reasonably believes may
lead to an Acquisition Proposal or for a waiver or release under any
"standstill" or similar agreement, the Company shall provide Parent with oral
and written notice of the material terms and conditions of such Acquisition
Proposal, indication, request or inquiry, and the identity of the person or
group making any such Acquisition Proposal, indication, request or inquiry. The
Company shall provide Parent as promptly as practicable notice (which may be
oral) setting forth all such information as is reasonably necessary to keep
Parent informed on a current basis of the status and details (including material
amendments or proposed material amendments) of any such Acquisition Proposal,
indication, request or inquiry.

                                       36
<PAGE>
                           (ii)     The Company shall provide Parent with
forty-eight (48) hours prior notice (or such lesser prior notice as is provided
to the members of its Board of Directors) of any meeting of its Board of
Directors at which its Board of Directors is reasonably expected to consider any
Acquisition Proposal.

                  (c)      Superior Offers. Notwithstanding anything to the
contrary contained in Section 4.2(a), if the Company receives an unsolicited,
bona fide written Acquisition Proposal that includes an indication of value in
excess of the Merger Consideration and that the Company Board of Directors has
in good faith concluded (following the receipt of the advice of its outside
legal counsel and its financial advisor), is from a person reasonably capable of
consummating such Acquisition Proposal and is or is reasonably likely to result
in, a Superior Offer, it may then take the following actions:

                           (i)      Furnish nonpublic information to the third
party making such Acquisition Proposal, request or inquiry provided that (A) (1)
concurrently with furnishing any such nonpublic information to such party, it
gives Parent notice of its intention to furnish nonpublic information and (2) it
receives from the third party an executed confidentiality agreement containing
customary limitations on the use and disclosure of all nonpublic written and
oral information furnished to such third party on its behalf, the terms of which
(x) shall not include any provision calling for any exclusive right to negotiate
with such party or having the effect of prohibiting the Company from satisfying
its obligations hereunder, and (y) shall, in all material respects, be no less
favorable to the Company than the Confidentiality Agreement between the Company
and Parent, dated as of November 2002, as amended on December 19, 2002 (the
"CONFIDENTIALITY AGREEMENT") and (B) contemporaneously with furnishing any such
nonpublic information to such third party, it furnishes such nonpublic
information to Parent (to the extent such nonpublic information has not been
previously so furnished); and

                           (ii)     Engage in negotiations with the third
party with respect to the Acquisition Proposal, provided that concurrently with
entering into negotiations with such third party, it gives Parent notice of its
intention to enter into negotiations with such third party.

                  (d)      Changes of Recommendation. In response to the receipt
of a Superior Offer, the Company Board of Directors may withhold, withdraw,
amend or modify its recommendation in favor of this Agreement and the Merger,
and, in the case of a Superior Offer that is a tender or exchange offer made
directly to its stockholders, may recommend that its stockholders accept the
tender or exchange offer (any of the foregoing actions, whether by the Company
Board of Directors or a committee thereof, a "CHANGE OF RECOMMENDATION"), if all
of the following conditions in clauses (i) through (iv) are met:

                           (i)      The Company Stockholders' Meeting has not
occurred;

                           (ii)     The Company delivers to Parent, no later
than concurrently with the Change of Recommendation, written notice (a "CHANGE
OF RECOMMENDATION NOTICE") of the Change of Recommendation, which notice shall
state the material terms and conditions of the Superior Offer and the identity
of the person or group making the Superior Offer;

                                       37
<PAGE>
                           (iii)    The Company Board of Directors has
concluded in good faith, after receipt of advice of its outside legal counsel,
that, in light of such Superior Offer, the failure of the Company Board of
Directors to effect a Change of Recommendation is reasonably likely to be
inconsistent with its fiduciary obligations to its stockholders under applicable
law; and

                           (iv)     The Company shall not have breached in any
material respect any of the restrictions set forth in this Section 4.2.

For a period of five (5) business days after delivering the Change of
Recommendation Notice, the Company shall provide Parent a reasonable opportunity
to make adjustments in the terms and conditions of this Agreement, and negotiate
in good faith with respect thereto.

                  (e)      Continuing Obligation to Call, Hold and Convene
Company Stockholders' Meeting; No Other Vote. Notwithstanding anything to the
contrary contained in this Agreement, unless this Agreement shall be terminated
in accordance with its terms, (i) the Company shall be obligated to call, give
notice of, convene and hold the Company Stockholders' Meeting regardless of the
commencement, disclosure, announcement or submission to it of any Acquisition
Proposal, or of any Change of Recommendation, and (ii) the Company shall not
submit to the vote of its stockholders any Acquisition Proposal, or propose to
do so.

                  (f)      Compliance with Tender Offer Rules. Nothing contained
in this Agreement shall prohibit the Company or its Board of Directors from
taking and disclosing to its stockholders a position contemplated by Rules 14d-9
and 14e-2(a) promulgated under the Exchange Act.

                  (g)      Certain Definitions. For purposes of this Agreement,
the following terms shall have the following meanings:

                           (i)      "ACQUISITION PROPOSAL" shall mean any offer
or proposal (whether or not subject to due diligence), relating to any
transaction or series of related transactions involving: (A) any acquisition by
any person or "GROUP" (as defined under Section 13(d) of the Exchange Act and
the rules and regulations thereunder) of more than a fifteen percent (15%)
interest in the total outstanding voting securities of the Company or any tender
offer or exchange offer that if consummated would result in any person or group
beneficially owning fifteen percent (15%) or more of the total outstanding
voting securities of the Company or any merger, consolidation, business
combination or similar transaction involving the Company or, (B) any sale, lease
(other than in the ordinary course of business), exchange, transfer, license
(other than in the ordinary course of business), acquisition by a third party of
more than fifteen percent (15%) of the assets of the Company (including its
subsidiaries taken as a whole) (provided, however, the Merger and the
transactions contemplated hereby shall not be deemed an Acquisition Proposal in
any case); and

                           (ii)     "SUPERIOR OFFER" shall mean an unsolicited,
bona fide written offer made by a third party to acquire, directly or
indirectly, pursuant to a tender offer, exchange offer, merger, consolidation or
other business combination, all or substantially all of the assets of the
Company or a majority of the total outstanding voting securities of the Company
on terms that the Company Board of Directors reasonably determined, in good
faith (following the receipt of

                                       38
<PAGE>
advice of its outside legal counsel and its financial adviser), (x) provides
consideration to stockholders of the Company that is more favorable, from a
financial point of view, than the Merger Consideration, (y) is not subject to
any financing condition (and any required financing is either fully committed or
otherwise reasonably determined to be available), and (z) is, taking into
account, among other things, all legal, financial, regulatory and other aspects
of the offer and the person making the offer, reasonably capable of being
consummated without significant additional delay.

                                   ARTICLE V

                              ADDITIONAL AGREEMENTS

         5.1      Proxy Statement. As promptly as practicable after the

of this Agreement and approval of the Merger by the stockholders of the Company.
Parent and the Company will provide each other with any information which may be
required in order to effectuate the preparation and filing of the preliminary
Proxy Statement. The Company shall cooperate and provide Parent (and its
counsel) with a reasonable opportunity to review and comment on the preliminary
Proxy Statement any amendment or supplement to the Proxy Statement prior to
filing such with the SEC, and will provide Parent with a copy of all such
filings made with the SEC. The Company will notify Parent upon the receipt of
any comments from the SEC or its staff in connection with the filing of, or
amendments or supplements to, the preliminary Proxy Statement. As promptly as
practicable after comments are received from the SEC thereon and after the
furnishing by the Company and Parent of all information required to be contained
therein, the Company shall file with the SEC a revised Proxy Statement and will
use all reasonable efforts to have it cleared by the SEC as soon thereafter as
practicable. The Company will cause the Proxy Statement to be mailed to its
stockholders at the earliest practicable time after it is cleared by the SEC.

         5.2      Meeting of Company Stockholders; Board Recommendation.

                  (a)     Meeting of Company Stockholders. Promptly after the
Proxy Statement is cleared by the SEC, the Company will take all action
necessary in accordance with the DGCL and its Certificate of Incorporation and
Bylaws to call, hold and convene a meeting of its stockholders to consider
adoption and approval of this Agreement and approval of the Merger (the "COMPANY
STOCKHOLDERS' MEETING") to be held as promptly as practicable after the Proxy
Statement is cleared by the SEC. Subject to Section 4.2(d), the Company will use
all 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 will
take all other action necessary or advisable to secure the vote or consent of
its stockholders required by the rules of the Nasdaq or the DGCL to obtain such
approvals. Notwithstanding anything to the contrary contained in this Agreement,
the Company may adjourn or postpone the Company Stockholders' Meeting if as of
the time for which the Company Stockholders' Meeting is originally scheduled (as
set forth in the Proxy Statement) 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 its in
connection

                                       39
<PAGE>
with the Company Stockholders' Meeting are solicited in compliance with the
DGCL, its Certificate of Incorporation and Bylaws, Nasdaq rules and all other
applicable Legal Requirements.

                  (b)     Board Recommendation. Except to the extent expressly
permitted by Section 4.2(d): (i) the Company Board of Directors shall recommend
that the Company's stockholders vote in favor of the adoption and approval of
this Agreement and approval of the Merger at the Company Stockholders' Meeting,
(ii) the Proxy Statement shall include a statement to the effect that the
Company Board of Directors has recommended that the Company's stockholders vote
in favor of adoption and approval of this Agreement and approval of the Merger
at the Company Stockholders' Meeting, and (iii) neither the Company Board of
Directors nor any committee thereof shall withdraw, amend or modify, or propose
or resolve to withdraw, amend or modify in a manner adverse to Parent, the
recommendation of the Company Board of Directors that the Company's stockholders
vote in favor of the adoption and approval of this Agreement and the approval of
the Merger.

         5.3      Confidentiality; Access to Information.

                  (a)      The parties acknowledge that the Company and Parent
have previously executed the Confidentiality Agreement. Unless otherwise
required by law or regulation (including Nasdaq rules) or pursuant to the terms
and provisions of the Confidentiality Agreement, the parties will hold any
information which is non-public in confidence in accordance with the terms of
the Confidentiality Agreement and, in the event this Agreement is terminated for
any reason, the parties shall promptly return or destroy such information in
accordance with the Confidentiality Agreement.

                  (b)      The Company will, subject to any limitations imposed
by applicable law, afford Parent and its officers, directors, employees, agents
and representatives (including, without limitation, any investment banker,
attorney or accountant retained by any of the foregoing) (such persons,
collectively, the "REPRESENTATIVES") (i) reasonable access during normal
business hours to the properties, books, analysis, projections, plans, systems,
contracts, commitments, records, personnel offices and other facilities of the
Company and its subsidiaries during the period prior to the Effective Time to
obtain all information concerning its business, including the status of product
development efforts, properties, results of operations and personnel of the
Company and (ii) use all reasonable efforts to make available at all reasonable
times during normal business hours to Parent and its Representatives, the
appropriate individuals (including management, personnel, attorneys, accountants
and other professionals) for discussion of the Company's business, properties,
prospects and personnel as Parent may reasonably request. During such period,
the Company shall (and shall cause its subsidiaries to), subject to any
limitations imposed by applicable law, furnish promptly to Parent (a) a copy of
each report, schedule, registration statement and other document filed or
received by it during such period pursuant to the requirements of federal
securities laws and (b) all other information concerning its business,
properties and personnel as Parent may reasonably request. No information or
knowledge obtained by Parent in any investigation pursuant to this Section 5.3
will affect or be deemed to modify any representation or warranty of the Company
contained herein or the conditions to the obligation of the Company to
consummate the Merger.

                                       40
<PAGE>
         5.4      Public Disclosure. The initial press release concerning the
Merger shall be a joint press release and, thereafter, neither Parent, Merger
Sub nor the Company will disseminate any press release or other announcement
concerning the Merger, this Agreement or the transactions contemplated hereby to
any third party without the prior written consent of each of the other parties
hereto (which consent shall not be unreasonably withheld), except as may be
required by any Legal Requirement or any listing agreement with Nasdaq or any
other applicable national or regional securities exchange, provided, that the
parties will consult with each other and use all reasonable efforts to agree on
any such required press release or public statement in advance. The parties have
agreed to the text of the joint press release announcing the execution of this
Agreement.

         5.5      Regulatory Filings; Reasonable Efforts.

                  (a)      Regulatory Filings. Each of Parent, Merger Sub and
the Company shall coordinate and cooperate with one another and shall each use
all reasonable efforts to comply with, and shall each refrain from taking any
action that would impede compliance with, all Legal Requirements, and as
promptly as practicable after the date hereof, each of Parent, Merger Sub and
the Company shall make all filings, notices, petitions, statements,
registrations, submissions of information, application or submission of other
documents required by any Governmental Entity in connection with the Merger and
the transactions contemplated hereby, including, without limitation: (i)
Notification and Report Forms with the United States Federal Trade Commission
(the "FTC") and the Antitrust Division of the United States Department of
Justice ("DOJ") as required by the HSR Act, (ii) any other filing necessary to
obtain any Necessary Consent, (iii) filings under any other comparable
pre-merger notification forms required by the merger notification or control
laws of any applicable jurisdiction, as agreed by the parties hereto, and (iv)
any filings required under the Securities Act, the Exchange Act, any applicable
state or securities or "blue sky" laws and the securities laws of any foreign
country, or any other Legal Requirement relating to the Merger. Each of Parent
and the Company will cause all documents that it is responsible for filing with
any Governmental Entity under this Section 5.5(a) to comply in all material
respects with all applicable Legal Requirements. Parent, Merger Sub and the
Company each shall promptly supply the other with any information which may be
required in order to effectuate any filings or application pursuant to this
Section 5.5(a).

                  (b)     Reasonable Efforts. Subject to the express provisions
of Section 4.2 and Section 5.2 hereof and upon the terms and subject to the
conditions set forth herein, each of the parties agrees to use all reasonable
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 in doing, all things
necessary, proper or advisable to consummate and make effective, in the most
expeditious manner practicable, the Merger and the transactions contemplated
hereby, including using all reasonable efforts to accomplish the following: (i)
the taking of all reasonable acts necessary to cause the conditions precedent
set forth in Article VI 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, and (iv) the
execution or delivery of any additional instruments necessary to consummate the

                                       41
<PAGE>
transactions and to carry out fully the purposes of, this Agreement. In
connection with and without limiting the foregoing, the Company and its Board of
Directors shall, if any takeover statute or similar Legal Requirement is or
becomes applicable to the Merger, this Agreement or any of the transactions
contemplated by this Agreement, use all 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 Legal Requirement on the
Merger, this Agreement and the transactions contemplated hereby.

                  (c)      Limitation on Divestiture and Litigation.
Notwithstanding anything in this Agreement to the contrary, nothing contained in
this Agreement shall be deemed to require Parent or the Company or any
subsidiary or affiliate thereof to (i) litigate or agree to litigate against any
Governmental Entity or (ii) take or agree to take any Action of Divestiture (as
defined below). For purposes of this Agreement, an "ACTION OF DIVESTITURE" shall
mean (i) making proposals, executing or carrying out agreements or submitting to
Legal Requirements providing for the license, sale or other disposition or
holding separate (through the establishment of a trust or otherwise) of any
assets or categories of assets that are material to Parent, the Company or any
of their respective subsidiaries or the holding separate of Company capital
stock or imposing or seeking to impose any limitation on the ability of Parent,
the Company or any of their respective subsidiaries, to conduct their respective
businesses or own such assets or to acquire, hold or exercise full rights of
ownership of the Company's business or (ii) otherwise taking any step to avoid
or eliminate any impediment which may be asserted under any Legal Requirement
governing competition, monopolies or restrictive trade practices.

         5.6      Notification of Certain Matters. The Company shall give prompt
notice to Parent and Merger Sub of any representation or warranty made by it
contained in this Agreement becoming untrue or inaccurate, or any failure of the
Company to comply with or satisfy in any 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 6.3(b) 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 Parent or Merger Sub under this Agreement.
Parent and Merger Sub shall give prompt notice to the Company of any
representation or warranty made by either of them contained in this Agreement
becoming untrue or inaccurate, or any failure of either of Parent or Merger Sub
to comply with or satisfy in any 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 6.2(b) 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 Company under this Agreement.

         5.7      Company Option Plans; Employee Stock Purchase Plan.

                  (a)      Unless Parent, Merger Sub and the Company agree
otherwise, Parent, Merger Sub and the Company shall take all actions necessary
to provide that, each outstanding option to purchase shares of Company Common
Stock (each, a "COMPANY OPTION," and collectively, the "COMPANY OPTIONS")
granted under the Company Option Plans and Non-Plan Option Agreements that is
outstanding immediately prior to the Effective Time, whether or not

                                       42
<PAGE>
then exercisable or vested, shall be assumed by Parent as of the Effective Time.
For purposes of the foregoing, the "COMPANY OPTION PLANS" shall mean those plans
set forth on Section 5.7 of the Company Disclosure Letter. As of the Effective
Time, each such Company Option shall cease to represent a right to acquire
shares of Company Common Stock and shall be converted automatically into an
option to purchase shares of Parent Common Stock in an amount, at an exercise
price and subject to such terms and conditions determined as provided below.
Each Company Option so assumed by Parent shall be subject to, and exercisable
and vested upon, the same terms and conditions as under the applicable Company
Option Plan or Non-Plan Option Agreement and the applicable option and other
related agreements issued thereunder, except that each assumed Company Option
shall be exercisable for, and represent the right to acquire, shares of Parent
Common Stock, the number of shares of Parent Common Stock (rounded down to the
nearest whole share) determined by multiplying the number of shares of Company
Common Stock subject to such Company Option by a fraction (the "OPTION EXCHANGE
RATIO"), the numerator of which is the Merger Consideration and the denominator
of which is the average closing price of Parent Common Stock on the Nasdaq
National Market over the ten trading days immediately preceding (but not
including) the date on which the Effective Time occurs, at an exercise price per
share of Parent Common Stock (rounded up to the nearest whole cent) equal to (A)
the per share exercise price for the shares of Company Common Stock otherwise
purchasable pursuant to such Company Option divided by (B) the Option Exchange
Ratio. If and to the extent necessary or required by the terms of the Company
Option Plans or Non-Plan Option Agreement or pursuant to the terms of any
Company Option granted thereunder, the Company shall use all reasonable efforts
to obtain the consent of each holder of outstanding Company Options to
effectuate the foregoing assumption of such Company Options. The Company agrees
that each of the Company Option Plans or Non-Plan Option Agreement and related
agreements shall be amended, to the extent necessary, to reflect the
transactions contemplated herein. Prior to the Effective Time, the Board of
Directors of Parent, or an appropriate committee of non-employee directors
thereof, shall adopt a resolution consistent with the interpretative guidance of
the SEC so that the assumption of the Company Options held by Company Insiders
(as defined below) shall be an exempt transaction for purposes of Section 16 of
the 1934 Act by any officer or director of Company who may become a covered
person of Parent for purposes of Section 16 of the 1934 Act (a "COMPANY
INSIDER").

                  (b)      The conversion of Company Options provided for in
Section 5.7(a), with respect to any options which are intended to be "incentive
stock options" (as defined in Section 422 of the Code) shall be effected in a
manner consistent with Section 424(a) of the Code.

                  (c)      Prior to the Effective Time, (i) the Company Board of
Directors shall pursuant to Section 19 of the Company's 1998 Employee Stock
Purchase Plan (the "ESPP"), shorten the Purchase Periods (as defined in the
ESPP) then in progress by setting a new Exercise Date (as defined in the ESPP)
that is prior to the Effective Time (the "NEW EXERCISE DATE") and notifying all
participants in the ESPP of such New Exercise Date at least ten (10) business
days prior to the New Exercise Date, and each participant's option under the
ESPP shall be exercised automatically on the New Exercise Date, unless prior to
such date such participant has withdrawn from the Offering Period, and any
Offering Periods (as defined in the ESPP) then in progress shall end on the New
Exercise Date, and (ii) the Company Board of Directors shall take all steps
necessary to terminate the ESPP prior to the Effective Time.

                                       43
<PAGE>
                  (d)      With respect to matters described in Section 5.7, the
Company will use all reasonable efforts to consult with Parent (and consider in
good faith the advice of Parent) prior to sending any notices or other
communication materials to its employees.

                  (e)      Parent shall provide, or cause its Subsidiaries or
the Surviving Corporation, as applicable, to provide each person who is employed
by Parent, its subsidiaries or the Surviving Corporation on or after the
Effective Time, and who was employed by the Company immediately prior to the
Effective Time, employee benefits (other than equity-based benefits) that are
substantially comparable in the aggregate to the employee benefits provided to
similarly-situated active employees of Parent, its Subsidiaries or the Surviving
Corporation.

                  (f)      As of the Effective Time, Parent will, or will cause
the Surviving Corporation to, honor the severance payments and benefits payable
under (i) the plans and agreements set forth in Section 2.12(c) of the Company
Disclosure Letter with respect to employees of the Company as of the date hereof
and on the terms of such plans and agreements as in effect on the date hereof,
or (ii) such severance plans and agreements that may be entered into before the
Effective Time with the written consent of Parent; provided that nothing herein
shall preclude Parent from modifying any such plan or agreement to the extent
consistent with this Section 5.7(f) or with the consent of the participant.
Parent acknowledges and agrees that the consummation of the transactions
contemplated hereby will constitute the "change of control" of the Company for
purposes of the plans and agreements set forth in Section 2.12(c) of the Company
Disclosure Letter, as applicable, and agrees to honor the provisions under such
plans and agreements relating to a change of control.

         5.8      Form S-8. Parent agrees to file with the SEC as soon as
practicable but no later than 20 days following the Effective Time a
registration statement on Form S-8 under the Securities Act covering, to the
extent applicable, the shares of Parent Common Stock to be issued upon the
exercise of Company Options assumed by Parent. Parent agrees to cause shares of
Parent Common Stock to be issued upon exercise of Company Options assumed by
Parent to be authorized for listing on the national securities exchange on which
the Parent Common Stock is listed.

         5.9      Company Rights Agreement. Except as set forth in Section 2.16,
the Company shall not redeem the Company Rights or amend or modify (including by
delay of the "Distribution Date" thereunder) or terminate the Company Rights
Agreement prior to the Effective Time unless, and only to the extent that it is
required to do so by order of a court of competent jurisdiction.

         5.10     Subsequent Financial Statements. To the extent reasonably
practicable, the Company shall consult with Parent prior to making publicly
available its financial results for any period after the date of this Agreement
and prior to filing any Company SEC Documents after the date of this Agreement,
it being understood that Parent shall have no liability by reason of such
consultation.

         5.11     Conveyance Taxes. Parent, Merger Sub and the Company shall
cooperate in the preparation, execution and filing of all returns,
questionnaires, applications or other documents regarding any real property
transfer or gains, sales, use, transfer, value added, stock transfer or

                                       44
<PAGE>
stamp taxes, any transfer, recording, registration or other fees or any similar
taxes which become payable in connection with the transactions contemplated by
this Agreement that are required or permitted to be filed on or before the
Effective Time.

         5.12     Indemnification.

                  (a)      For a period of 6 years after the Effective Time,
Parent will or will cause the Surviving Corporation to fulfill and honor in all
respects the obligations of Company pursuant to any indemnification agreements
between the Company and its directors and officers as of the Effective Time (the
"INDEMNIFIED PARTIES") and any indemnification provisions under the Company's
certificate of incorporation or bylaws as in effect on the date hereof. The
certificate of incorporation and bylaws of the surviving Corporation will
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, which provisions will not be amended, repealed or otherwise modified for
a period of 6 years from the Effective Time in any manner that would adversely
affect the rights thereunder of individuals who, immediately prior to the
Effective Time, were directors or officers of the Company, unless such
modification is required by law; provided that the Surviving Corporation may
reincorporate in another U.S. state that prohibits indemnification on terms as
favorable as Delaware's so long as the Surviving Corporation provides for the
maximum allowable indemnification in its certificate of incorporation and bylaws
and so long as Parent provides supplemental contractual indemnification such
that the indemnification provided by such certificate of incorporation and
bylaws and such contractual provisions is equivalent to the level of
indemnification provided to such directors and officers as of the date of this
Agreement.

                  (b)      For a period of 6 years after the Effective Time,
Parent will or will cause the Surviving Corporation to use its commercially
reasonable efforts to maintain in effect, if available, directors' and officers'
liability insurance covering those persons who are currently covered by
Company's directors' and officers' liability insurance policy on terms
comparable to those applicable to the current directors and officers of Company;
provided, however, that in no event will the Surviving Corporation be required
to expend in excess of 150% of the annual premium currently paid by Company for
such coverage (the "CURRENT ANNUAL PREMIUM AMOUNT") (but shall in any event
provide and maintain such coverage as is available for such 150% of such annual
premium). The Current Annual Premium Amount is set forth in Section 5.12 of the
Company Disclosure Letter.

                  (c)      This Section 5.12 shall survive the consummation of
the Merger, is intended to benefit the Company, the Surviving Corporation and
each indemnified party, shall be binding on all successors and assigns of the
Surviving Corporation and Parent, and shall be enforceable by the Indemnified
Parties.

         5.13     Silicon Valley Bank Facility. Upon the request of Parent,
the Company agrees to discuss in good faith with Parent the potential repayment
of obligations pursuant to the Company's credit agreement with Silicon Valley
Bank, and the discharge of the security interests and liens associated
therewith, prior to the Effective Time; provided that (i) the Company shall not
be required to take any action that in its judgment would impair its liquidity
or its ability to

                                       45
<PAGE>
operate its business and (ii) Parent will be responsible for all out-of-pocket
expenses associated with any such repayment by the Company.

                        TERMINATION, AMENDMENT AND WAIVER

         7.1      Termination. This Agreement may be terminated at any time
prior to the Effective Time, by action taken or authorized by the Board of
Directors of the terminating party or parties, and except as provided below,
whether before or after the requisite approval of the stockholders of the
Company:

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

                  (b)      by either the Company or Parent if the Merger shall
not have been consummated by May 31, 2003 (which date shall be extended to July
31, 2003, if the Merger shall not have been consummated as of the result of a
failure to satisfy the conditions set forth in Section 6.1(b), Section 6.1(c) or
Section 6.1(d)) (as appropriate, the "END DATE"); 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 material breach of this Agreement;

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

                  (d)      by either the Company or Parent if the required
approval of the stockholders of the Company contemplated by this Agreement shall
not have been obtained by reason of the failure to obtain the required vote at a
meeting of the Company stockholders duly convened therefor or at any adjournment
thereof; provided, however, that the right to terminate this Agreement under
this Section 7.1(d) shall not be available to the Company where the failure to
obtain the Company stockholder approval shall have been caused by the action or
failure to act of the Company and such action or failure to act constitutes a
material breach by the Company of this Agreement;

                  (e)      by Parent (at any time prior to the adoption and
approval of this Agreement and the Merger by the required vote of the
stockholders of the Company) if a Triggering Event with respect to the Company
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) 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, that if
such inaccuracy in Parent's representations and warranties or breach by Parent
is curable by Parent prior to the End Date through the exercise of reasonable
efforts, then the Company may not terminate this Agreement under this Section
7.1(f) prior to 30 days following the receipt of written notice from

                                       48
<PAGE>
the Company to Parent of such breach, provided that Parent continues to exercise
all reasonable efforts to cure such breach through such 30-day period (it being
understood that the Company may not terminate this Agreement pursuant to this
paragraph (f) if it shall have materially breached this Agreement or if such
breach by Parent is cured within such 30-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 the Company shall have become
untrue, in either case such that the conditions set forth in Section 6.3(a) or
Section 6.3(b) 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, that if
such inaccuracy in the Company's representations and warranties or breach by the
Company is curable by the Company prior to the End Date through the exercise of
reasonable efforts, then Parent may not terminate this Agreement under this
Section 7.1(g) prior to 30 days following the receipt of written notice from
Parent to the Company of such breach, provided that the Company continues to
exercise all reasonable efforts to cure such breach through such 30 day period
(it being understood that Parent may not terminate this Agreement pursuant to
this paragraph (g) if it shall have materially breached this Agreement or if
such breach by the Company is cured within such 30 day period); and

                  (h)      by the Company, if, prior to the adoption and
approval of this Agreement and approval of the Merger by the required vote of
the stockholders of the Company, the Company Board of Directors has provided
written notice to Parent that the Company intends to enter into a binding
written agreement for a Superior Offer (with such termination becoming effective
upon the Company entering into such binding written agreement); provided,
however, that (i) the Company shall have complied with Section 4.2 in all
material respects; (ii) the Company shall have delivered to Parent a Change in
Recommendation Notice with respect to such Superior Offer and such Change of
Recommendation Notice complies with the requirements of Section 4.2(d); (iii)
Parent does not make, within 72 hours after receipt of the Company's written
notice pursuant to this Section 7.1(h), an offer that the Company Board of
Directors shall have reasonably concluded in good faith (following consultation
with its financial advisor and outside counsel) is at least as favorable to the
stockholders of the Company as such Superior Offer; (iv) the Company Board of
Directors shall have received an opinion from each of TWP and an additional
investment banking firm of national reputation to the effect that the
consideration to be provided to the stockholders of the Company by such Superior
Offer is superior from a financial point of view to that provided by the Merger
Consideration; and (v) the Company pays the Termination Fee in accordance with
Section 7.3(b) concurrently with entering into such binding written agreement.

                  For the purposes of this Agreement, a "TRIGGERING EVENT," with
respect to the Company, shall be deemed to have occurred if: (i) its Board of
Directors or any committee thereof shall for any reason have withdrawn or shall
have amended or modified in a manner adverse to Parent its recommendation in
favor of, the adoption and approval of the Agreement or the approval of the
Merger, (ii) it shall have failed to include in the Proxy Statement the
recommendation of its Board of Directors in favor of the adoption and approval
of the Agreement and the approval of the Merger, (iii) its Board of Directors
fails to reaffirm (publicly, if so requested) its recommendation in favor of the
adoption and approval of the Agreement and the approval of the Merger within 10
business days after the other party hereto requests in

                                       49
<PAGE>
writing that such recommendation be reaffirmed following the public announcement
of any Acquisition Proposal, (iv) its Board of Directors or any committee
thereof shall have approved or recommended any Acquisition Proposal, (v) a
tender or exchange offer relating to its securities 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 10 business days after such tender or exchange offer is first published,
sent or given, a statement disclosing that the Company Board of Directors
recommends rejection of such tender or exchange offer, or (vi) the Company shall
have delivered a Change of Recommendation Notice.

         7.2      Notice of Termination; Effect of Termination. Any termination
of this Agreement under Section 7.1 above will be effective immediately upon the
delivery of a valid written notice of the terminating party to the other party
hereto. In the event of the termination of this Agreement as provided in Section
7.1, this Agreement shall be of no further force or effect, except (i) as set
forth in Section 5.3(a), this Section 7.2, Section 7.3 and Article VIII, each of
which shall survive the termination of this Agreement and (ii) nothing herein
shall relieve any party from liability for any willful material breach of this
Agreement. No termination of this Agreement shall affect the obligations of the
parties contained in the Confidentiality Agreement, all of which obligations
shall survive termination of this Agreement in accordance with their terms.

7.1(b), (d), (e), (g) (but only if the breach referred to in Section 7.1(g) is a
willful breach) or (h), the Company shall promptly, but in no event later than
two business days after the date of such termination (except as provided in
Section 7.1(h)), pay Parent a fee equal to eleven million two hundred thousand
dollars ($11,200,000) in immediately available funds (the "TERMINATION FEE");
provided, that in the case of termination under Section 7.1(b) or 7.1(d): (A)
such payment shall be made only if following the date hereof and prior to the
termination of this Agreement, there has been public disclosure of an
Acquisition Proposal with respect to the Company and within 12 months following

consideration in any

                                       50
<PAGE>
such Acquisition, valued as of the date the agreement related to such
Acquisition Proposal is entered into by the Company, is in excess of the Merger
Consideration, and (B) such payment shall be made promptly, but in no event
later than 2 business days after the consummation of such Acquisition of the
Company.

                           (ii)     Interest and Costs; Other Remedies. The
Company acknowledges that the agreements contained in this Section 7.3(b) are an

purposes of this Section 7.3(b) only, "ACQUISITION," with respect to the
Company, shall mean any of the following transactions (other than the
transactions contemplated by this Agreement): (i) the Company merges or
consolidates with or into, or is acquired, directly or indirectly, by merger,

group), directly or indirectly, of beneficial ownership or a right to acquire
beneficial ownership of shares representing in excess of 40% 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, by action taken or authorized by their respective
Boards of Directors, at any time before or after approval of the matters
presented in connection with the Merger by the stockholders of Parent and the
Company, provided, that after any such approval, no amendment shall be made
which by law or requires further approval by such stockholders without such
further stockholder approval. This Agreement may not be amended except by
execution of an instrument in writing signed on behalf of each of Parent, Merger
Sub and the Company.

         7.5      Extension; Waiver. At any time prior to the Effective Time any

(ii) waive any inaccuracies in the representations and warranties made to such
party contained herein or in any document delivered pursuant hereto, 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. Delay in exercising any right under this
Agreement shall not constitute a waiver of such right.

ADVERSE EFFECT" when used in connection with an entity, means any change, event,
circumstance or occurrence that has a material adverse effect on the business,
assets (including intangible assets), financial condition or results of
operations of such entity taken as a whole with its subsidiaries; provided,
however, that in no event shall any change, event, circumstances or occurrence
resulting from any of the following be taken into account in determining whether
there has been or will be, a Material Adverse Effect on any entity: (A) any
action required or expressly contemplated to be taken or prohibited from being
taken pursuant to this Agreement, (B) any matters referred to in Schedule 8.3,
(C) the announcement or pendency of the Merger, including litigation relating to
the proposed Merger, (D) the failure of such entity to meet published revenue or
earnings projections, (E) any change in such entity's stock price or trading
volume, (F) general business or economic conditions, or (G) changes affecting
the principal industries in which such entity operates (which changes do not
disproportionately affect such entity).

                  (f)      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.

                  (g)      For purposes of this Agreement, a "SUBSIDIARY" of a
specified entity shall mean any corporation, partnership, limited liability
company, joint venture or other legal entity of which the specified entity
(either alone or through or together with any other subsidiary) owns, directly
or indirectly, 50% or more of the stock or other equity or partnership interests
the holders of which are generally entitled to vote for the election of the
Board of Directors or other

                                       53

governing body of such corporation or other legal entity. Reference to the
subsidiaries of an entity shall be deemed to include all direct and indirect
subsidiaries of such entity.

         8.4      Counterparts. This Agreement may be executed in two or more
counterparts, and by facsimile, 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 and the Parent Disclosure Letter (a) 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
provisions of this Agreement shall supersede any conflicting provisions of the
Confidentiality Agreement, and (b) are not intended to confer upon any other
person any rights or remedies hereunder, except as specifically provided in
Section 5.12.

         8.6      Severability. If 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 if 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. In addition, each of the parties hereto (a) consents to submit
itself to the personal jurisdiction of any federal court located in the State of
Delaware or any Delaware state court in the event any dispute arises out of this
Agreement or any of the transactions contemplated by this Agreement, (b) agrees
that it will not attempt to deny or defeat such personal jurisdiction by motion
or other request for leave from any such court and irrevocably waives, to the
fullest extent permitted by law, any objection that it may now or hereafter have
to the laying of the venue of any suit, action or proceeding in any

                                       54
<PAGE>
such court or that any suit, action or proceeding brought in any such court has
been brought in an inconvenient forum and (c) except as expressly provided in
Section 8.7, agrees that it will not bring any action relating to this Agreement
or any of the transactions contemplated by this Agreement in any court other
than a federal or state court sitting in the State of Delaware. Process may be
served on any party anywhere in the world, whether within or without the
jurisdiction of any such court. Without limiting the foregoing, each party
agrees that service of process on such party as provided in Section 8.2 shall be
deemed effective service of process on such party.

         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. This Agreement shall not be assigned by any of
the parties hereto (whether by operation of law or otherwise) without the prior
written consent of the other parties, except that Merger Sub may assign, in its
sole discretion and without the consent of any other party, any or all of its
rights, interests and obligations hereunder to (i) Parent, (ii) to Parent and
one or more direct or indirect wholly-owned subsidiaries of Parent, or (iii) to
one or more direct or indirect wholly-owned subsidiaries of Parent. Subject to
the preceding sentence, but without relieving any party hereto of any obligation
hereunder, this Agreement will be binding upon, inure to the benefit of and be
enforceable by the parties and their respective successors and assigns.

         8.11     No Waiver; Remedies Cumulative. No failure or delay on the
part of any party hereto in the exercise of any right hereunder will impair such
right or be construed to be a waiver of, or acquiescence in, any breach of any
representation, warranty or agreement herein, nor will any single or partial
exercise of any such right preclude other or further exercise thereof or of any
other right. All rights and remedies existing under this Agreement are
cumulative to, and not exclusive to, and not exclusive of, any rights or
remedies otherwise available.

         8.12     Waiver of Jury Trial. EACH OF PARENT, THE COMPANY AND MERGER
SUB HEREBY IRREVOCABLY WAIVES ALL RIGHT TO TRIAL BY JURY IN ANY ACTION,
PROCEEDING OR COUNTERCLAIM (WHETHER BASED ON CONTRACT, TORT OR OTHERWISE)
ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED
HEREBY OR THE ACTIONS OF PARENT, THE COMPANY OR MERGER SUB IN THE NEGOTIATION,
ADMINISTRATION, PERFORMANCE AND ENFORCEMENT HEREOF.
