                                  ARTICLE II

                MERGER CONSIDERATION; EXCHANGE OF CERTIFICATES
                ----------------------------------------------

     SECTION 2.01  Merger Consideration.
                   --------------------

          (a)  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 of
the following securities:

               (i)  each share of Company Common Stock issued and outstanding
immediately prior to the Effective Time (other than any shares of Company Common
Stock to be canceled pursuant to Section 2.01(a)(ii) and any Dissenting Shares
(as defined in Section 2.05)) shall be converted into the right to receive the
Common Exchange Ratio (as defined in Section 2.01(b));

               (ii) each share of Company Stock held in the treasury of the
Company and each share of Company Stock owned by Parent or any direct or
indirect wholly owned subsidiary of Parent or of the Company immediately prior
to the Effective Time shall be

                                       3
<PAGE>

cancelled and extinguished without any conversion thereof and no payment or
distribution shall be made with respect thereto; and

               (iii)    each share of Common Stock, $.01 par value per share, of
Merger Sub issued and outstanding immediately prior to the Effective Time shall
be converted into and exchanged for one validly issued, fully paid and
nonassessable share of Common Stock, $.01 par value per share, of the Surviving
Corporation.

         (b)   As used in this Agreement, the following terms have the following
meanings:

               (i)      "Aggregate Merger Consideration" means 3,504,274 shares
                         ------------------------------
of Parent Common Stock (the "Parent Shares").
                             -------------

               (ii)     "Escrow Shares" means 350,427 Parent Shares.
                         -------------

               (iii)    "Common Exchange Ratio" means 0.107657 of a share of
                         ---------------------
Parent Common Stock; provided, however, that to the extent that the Company's
                     --------  -------
capitalization representation in Section 3.04 is incorrect or the Company
breaches the covenant contained in Section 5.01(b), with such breach of the
covenant resulting in additional securities of the Company being outstanding,
the Common Exchange Ratio shall be appropriately adjusted as of the Closing to
reflect such error or breach.

         (c)   If, during the period between the date hereof and the Effective
Time, any change in the capital stock of Parent shall occur by reason of
reclassification, recapitalization, stock split or combination, exchange or
readjustment of shares, or any stock dividend thereon with a record date during
such period or any similar event, the Aggregate Merger Consideration, the Common
Exchange Ratio and the Escrow Shares shall be correspondingly adjusted to the
extent appropriate to reflect such stock dividend, subdivision,
reclassification, recapitalization, split, combination, exchange or readjustment
of shares.

         (d)   If any shares of Company Common Stock outstanding immediately
prior to the Effective Time are unvested and/or are subject to a repurchase
option, risk of forfeiture or other condition under any applicable restricted
stock purchase agreement, stock option exercise agreement or other agreement
with the Company, then the Parent Shares issued in exchange for such shares of
Company Common Stock will also be unvested and/or subject to the same repurchase
option, risk of forfeiture or other condition, and the certificates representing
such Parent Shares may accordingly be marked with appropriate legends.

    SECTION 2.02 Exchange of Certificates.
                 ------------------------

         (a)   Exchange Procedures. From and after the Effective Time, a bank or
               -------------------
trust company to be designated by Parent shall act as exchange agent (the
"Exchange Agent") in effecting the exchange of the applicable Parent Shares for
 --------------
certificates that immediately prior to the Effective Time represented
outstanding shares of Company Stock ("Company Share Certificates") and that were
                                      --------------------------
converted into the right to receive the applicable Parent Shares pursuant to
Section 2.01. As promptly as practicable after the Effective Time, Parent and
the Exchange Agent shall mail to each record holder of Company Share
Certificates a letter of

                                       4
<PAGE>

transmittal (the "Letter of Transmittal") in a form approved by Parent and the
                  ---------------------
Company and instructions for use in surrendering such Company Share Certificates
and receiving Parent Shares pursuant to Section 2.01. Promptly after the
Effective Time, but in no event later than 5 business days following the
Effective Time, Parent shall cause to be deposited in trust with the Exchange
Agent the Parent Shares (and cash in lieu of fractional shares pursuant to
Section 2.02(e)) less the Escrow Shares.

                  Upon the surrender of each Company Share Certificate for
cancellation to the Exchange Agent, together with a properly completed Letter of
Transmittal and such other documents as may reasonably be required by Parent:

                         (i)   Parent shall cause to be issued to the holder of
such Company Share Certificate in exchange therefor a separate stock certificate
representing the Parent Shares to which such holder is entitled pursuant to
Section 2.01 (less the Escrow Shares attributable to the pro rata interest of
such holder in the Escrow Fund pursuant to Section 2.02(b)) and cash in lieu of
fractional shares pursuant to Section 2.02(e); and

                         (ii)  the Company Share Certificates so surrendered
shall forthwith be cancelled.

                  In the event of a transfer of ownership of shares of Company
Stock that is not registered in the transfer records of the Company, the
applicable Parent Shares may be issued to a person other than the person in
whose name the Company Share Certificate so surrendered is registered if the
Company Share Certificate representing such shares of Company Stock is presented
to Parent, accompanied by all documents required to evidence and effect such
transfer and evidence that (i) the shares are transferable and (ii) any
applicable stock transfer taxes have been paid.

                  Until surrendered as contemplated by this Article II, each
Company Share Certificate shall, subject to appraisal rights under the DGCL, the
California Corporations Code ("California Law") and Section 2.05, be deemed at
                               --------------
any time after the Effective Time to represent only the right to receive upon
surrender the applicable Parent Shares with respect to the shares of Company
Stock formerly represented thereby to which such holder is entitled pursuant to
Section 2.01 and cash in lieu of any fractional shares pursuant to Section
2.02(e).

                  (b)    Escrow Fund. Prior to or simultaneously with the
                         -----------
Closing, the Stockholders' Representative and Parent shall enter into an escrow
agreement (the "Escrow Agreement") with an escrow agent selected by Parent and
                ----------------
reasonably acceptable to the Stockholders' Representative (the "Escrow Agent"),
                                                                ------------
substantially in the form of Exhibit C hereto. Pursuant to the terms of the
                             ----------------
Escrow Agreement, at the Closing, Parent shall deposit one or more certificates
representing, in the aggregate, the Escrow Shares to be deposited by each holder
of Company Stock into an escrow account, which account is to be managed by the
Escrow Agent (the "Escrow Account"). Any Escrow Shares in the Escrow Account are
                   --------------
referred to herein as the "Escrow Fund." In connection with such deposit of the
                           -----------
Escrow Shares with the Escrow Agent and as of the Effective Time, each holder of
Company Stock will be deemed to have received and deposited with the Escrow
Agent each stockholder's pro rata interest in the Escrow Fund as determined as
of Closing by reference to such stockholder's ownership of shares

                                       5
<PAGE>

of Company Stock (plus any additional shares as may be issued upon any stock
split, stock dividend or recapitalization effected by Parent after the Effective
Time with respect to shares constituting the Escrow Fund), without any act of
any stockholder of the Company. Distributions of any Escrow Shares from the
Escrow Account shall be governed by the terms and conditions of the Escrow
Agreement. The adoption of this Agreement and the approval of the Merger by the
stockholders of the Company (the "Company Stockholders") shall constitute
                                  ------- ------------
approval of the Escrow Agreement and of all the arrangements relating thereto,
including, without limitation, the placement of the Escrow Shares in escrow and
the appointment of the Stockholders' Representative. No Escrow Shares shall be
contributed in respect of any Company Option or any other security exercisable
or convertible into Company Stock. The percentage of Parent Shares contributed
to the Escrow Fund with respect to each holder of Company Stock that are
unvested or subject to any right of repurchase, risk of forfeiture or other
condition in favor of the Surviving Corporation shall be proportional to the
percentage of such holder's Company Stock that are unvested or subject to any
right of repurchase, risk of forfeiture or other condition in favor of the
Company; provided, however, that any payments due to Parent from the Escrow Fund
         --------  -------
shall first be satisfied by delivering to Parent, to the extent available, with
respect to each holder of Company Stock, such Escrow Shares that are fully
vested or otherwise not subject to any right of repurchase, risk of forfeiture
or other restriction in favor of the Surviving Corporation.

               (c) Distributions with Respect to Unexchanged Parent Shares. No
                   -------------------------------------------------------
dividends or other distributions declared or made after the Effective Time with
respect to Parent Shares comprising part of the Aggregate Merger Consideration
with a record date after the Effective Time shall be paid to the holder of any
unsurrendered Company Share Certificate with respect to the Parent Shares
represented thereby until the holder of such Company Share Certificate shall
surrender such Company Share Certificate in accordance with this Section 2.02.

               (d) No Further Rights in Company Stock. All Parent Shares issued
                   ----------------------------------
upon conversion of shares of Company Stock in accordance with the terms hereof
(and any cash paid in lieu of fractional shares pursuant to Section 2.02(e))
shall be deemed to have been issued in full satisfaction of all rights
pertaining to such shares of Company Stock.

               (e) No Fractional Shares. No certificates or scrip representing
                   --------------------
fractional Parent Shares shall be issued upon the surrender for exchange of
Company Share Certificates, and such fractional share interests will not entitle
the owner thereof to vote or to any other rights of a stockholder of Parent.
Each holder of a fractional share interest shall be paid an amount in cash
(without interest) equal to the product obtained by multiplying (i) such
fractional share interest to which such holder (after taking into account all
fractional share interests then held by such holder) would otherwise be entitled
by (ii) $117.

               (f) No Liability. Neither Parent nor the Surviving Corporation
                   ------------
shall be liable to any holder of shares of Company Stock for any such shares of
Company Stock (or dividends or distributions with respect thereto) or cash
properly and legally delivered to a public official pursuant to any abandoned
property, escheat or similar law.

               (g) Withholding Rights. Each of the Surviving Corporation and
                   ------------------
Parent shall be entitled to deduct and withhold from the consideration otherwise
payable pursuant to this

                                       6
<PAGE>

Agreement to any holder of shares of Company Stock such amounts as it is
required to deduct and withhold with respect to the making of such payment under
the Code, or any provision of state, local or foreign tax law. To the extent
that amounts are so withheld by the Surviving Corporation or Parent, as the case
may be, such withheld amounts shall be treated for all purposes of this
Agreement as having been paid to the holder of the shares of Company Stock in
respect of which such deduction and withholding was made by the Surviving
Corporation or Parent, as the case may be.

               (h) Affiliates. Notwithstanding anything to the contrary
                   ----------
contained in this Agreement, no Parent Shares (or certificates therefor) shall
be issued in exchange for any Company Stock Certificates to any person who,
prior to the Effective Time, may be an "affiliate" (as that term is used in Rule
145 under the Securities Act of 1933, as amended (the "Securities Act")) of the
Company until such person shall have delivered to Parent and the Company a duly
executed Affiliate Agreement as contemplated by Section 6.09.

               (i) Lost Certificates. If any Company Share Certificate shall
                   -----------------
have been lost, stolen or destroyed, upon the making of an affidavit of that
fact by the person claiming such Company Share 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 Company Share Certificate, Parent shall issue in exchange for such lost,
stolen or destroyed Company Share Certificate, the applicable Parent Shares (and
dividends or other distributions pursuant to Section 2.02(c) and cash in lieu of
fractional shares pursuant to Section 2.02(e)) to which such person is entitled
pursuant to the provisions of this Article II.

               (j) Return of Parent Shares. Promptly following the end of the
                   -----------------------
second full calendar month after the Effective Time, the Exchange Agent shall
return to the Surviving Corporation all of the remaining Parent Shares and the
Exchange Agent's duties shall terminate. Thereafter, upon the surrender of a
Company Share Certificate to the Surviving Corporation and such other documents
as may reasonably be required by the Surviving Corporation, and subject to
applicable abandoned property, escheat and similar laws, the holder of such
Company Share Certificate shall be entitled to receive in exchange therefor the
applicable Parent Shares (and dividends or other distributions pursuant to
Section 2.02(c) and cash in lieu of fractional shares pursuant to Section
2.02(e)) without any interest thereon.

          SECTION 2.03 Stock Transfer Books. At the Effective Time, the stock
                       --------------------
transfer books of the Company shall be closed and there shall be no further
registration of transfers of shares of Company Stock thereafter on the records
of the Company. From and after the Effective Time, the holders of certificates
representing shares of Company Stock outstanding immediately prior to the
Effective Time shall cease to have any rights with respect to such shares of
Company Stock, except as otherwise provided in this Agreement or by Law (as
defined in Section 3.06).

          SECTION 2.04 Company Stock Options. At the Effective Time, the Parent
                       ---------------------
shall assume (i) all options to purchase Common Stock issued by the Company
pursuant to the Company Stock Plans (as defined in Section 3.04(b)) or
otherwise, whether vested or unvested (each a "Company Option"), and (ii) the
Company Stock Plans, with respect to outstanding

                                       7
<PAGE>

Company Options. Immediately after the Effective Time, each Company Option
outstanding immediately prior to the Effective Time shall be deemed to
constitute an option to acquire, on the same terms and conditions as were
applicable under such Company Option at the Effective Time, such number of
shares of Parent Common Stock as is equal to the number of shares of Company
Common Stock subject to the unexercised portion of such option multiplied by the
Common Exchange Ratio (rounded down to the nearest whole number). The exercise
price per share of each such assumed Company Option shall be equal to the
exercise price of such option immediately prior to the Effective Time divided by
the Common Exchange Ratio (rounded up to the nearest whole cent). The term,
vesting schedule, status as an "incentive stock option" under Section 422 of the
Code, if applicable, and all of the other terms of the Company Options shall
otherwise remain unchanged. It is the intention of the parties that the Company
Options so assumed by Parent qualify following the Effective Time as incentive
stock options as defined in Section 422 of the Code to the extent such Company
Options qualified as incentive stock options prior to the Effective Time.
Continuous employment with the Company will be credited to the holder of a
Company Option for purposes of determining the number of shares of Parent Common
Stock subject to exercise after the Effective Time. Within 30 business days
after the Effective Time, Parent will issue to each person who, immediately
prior to the Effective Time, was a holder of a Company Option a document
evidencing the foregoing assumption of such option by Parent. Promptly after the
Effective Time, but in any event not later than 20 days after the Effective
Time, Parent shall file a registration statement on Form S-8 (or any successor
or other appropriate forms) that will register the shares of Parent Common Stock
subject to assumed Company Options to the extent permitted by Federal securities
laws and shall use its commercially reasonable efforts to maintain the
effectiveness of such registration statement or registration statements (and
maintain the current status of the prospectus or prospectuses contained therein)
for so long as such options remain outstanding.

          SECTION 2.05 Dissenting Shares.
                       -----------------

               (a) Notwithstanding any provision of this Agreement to the
contrary, shares of Company Stock that are outstanding immediately prior to the
Effective Time and that are held by stockholders who have exercised and
perfected appraisal rights for such shares of Company Stock in accordance with
the DGCL (and, if the Company is subject to Section 2115 of the California Law,
such rights as may be granted to such persons in Chapter 13 of the California
Law) (collectively, the "Dissenting Shares") shall not be converted into or
                         -----------------
represent the right to receive the applicable Parent Shares (or cash in lieu of
fractional shares). Such stockholders shall be entitled to receive payment of
the appraised value of such shares of Company Stock held by them in accordance
with the DGCL (and, if Company is subject to Section 2115 of the California Law,
such rights as may be granted to such persons in Chapter 13 of the California
Law), unless and until such stockholders fail to perfect or withdraw or
otherwise lose their appraisal rights under the DGCL (or, if applicable, Chapter
13 of the California Law). All Dissenting Shares held by stockholders who shall
have failed to perfect or who effectively shall have withdrawn or lost their
rights to appraisal of such shares of Company Stock under the DGCL (or, if
applicable, Chapter 13 of the California Law) shall thereupon be deemed to have
been converted into and to have become exchangeable for, as of the Effective
Time, the right to receive the applicable Parent Shares (or cash in lieu of
fractional shares), without any interest thereon, upon surrender, in the manner
provided in Section 2.02, including

                                       8
<PAGE>

the provision of the Escrow Shares pursuant to Section 2.02(b), of their Company
Share Certificates.

               (b) The Company shall give Parent (i) prompt notice of any
demands for appraisal received by the Company, withdrawals of such demands, and
any other related instruments served pursuant to the DGCL (or, if applicable,
Chapter 13 of the California Law) and received by the Company and (ii) the
opportunity to direct all negotiations and proceedings with respect to demands
for appraisal under the DGCL (or, if applicable Chapter 13 of the California
Law). The Company shall not, except with the prior written consent of Parent,
make any payment with respect to any demands for appraisal or offer to settle or
settle any such demands.

                                  ARTICLE III
                                  -----------

                 REPRESENTATIONS AND WARRANTIES OF THE COMPANY
                 ---------------------------------------------

          Except as set forth in the disclosure schedule delivered by the
Company to Parent and Merger Sub concurrently with the execution of this
Agreement (the "Company Disclosure Schedule"), which provides an exception to,
                ---------------------------
or otherwise qualifies in reasonable detail and with specific Section
references, the representations or warranties of the Company herein, the Company
hereby represents and warrants to Parent and Merger Sub that:

          SECTION 3.01 Organization and Qualification. The Company is a
                       ------------------------------
corporation duly incorporated, validly existing and in good standing under the
laws of the State of Delaware and has all requisite corporate power and
authority to own, lease and operate its properties and to carry on its business
as it is now being conducted, except where the failure to be so organized,
existing or in good standing or to have such corporate power and authority have
not had, and could not reasonably be expected to have, individually or in the
aggregate, a Company Material Adverse Effect (as defined below). The Company is
duly qualified or licensed as a foreign corporation to do business, and is in
good standing, in each jurisdiction where the character of the properties owned,
leased or operated by it or the nature of its business makes such qualification
or licensing necessary, except where the failure to be so qualified or licensed
and in good standing have not had, and could not reasonably be expected to have,
individually or in the aggregate, a Company Material Adverse Effect. The term
"Company Material Adverse Effect" means any change in or effect on the business
 -------------------------------
of the Company that is, or could reasonably be expected to be, materially
adverse to the business, operations, condition (financial or otherwise), assets
(tangible or intangible), liabilities or results of operations of the Company
taken as a whole, except for any such changes or effects principally resulting
from or principally arising in connection with (i) any occurrence or condition
affecting the market for Internet streaming technology generally that does not
disproportionately impact the Company, (ii) any changes in general economic
conditions or (iii) the effect of the public announcement or pendency of the
transactions contemplated by this Agreement on the customers, suppliers,
advertisers, employees or revenues of the Company.

          SECTION 3.02 Certificate of Incorporation and Bylaws. The Company has
                       ---------------------------------------
heretofore made available to Parent a complete and correct copy of (a) the
Certificate of Incorporation and the Bylaws of the Company, including all
amendments thereto, (b) the minute

                                       9
<PAGE>

books containing all consents, actions and meetings of the stockholders of the
Company and the Company's Board of Directors and any committees thereof, and (c)
the stock transfer books of the Company setting forth all issuances or transfers
of any capital stock of the Company. Such Certificate of Incorporation and
Bylaws are in full force and effect. The Company is not in violation of any of
the provisions of its Certificate of Incorporation or Bylaws. The corporate
minute books, stock certificate books, stock registers and other corporate
records of the Company are complete and accurate, and the signatures appearing
on all documents contained therein are the true or facsimile signatures of the
persons purported to have signed the same.

          SECTION 3.03 Subsidiaries. The Company does not control, directly or
                       ------------
indirectly, or have any direct or indirect equity participation or similar
interest in any corporation, partnership, limited liability company, joint
venture, trust or other business association.

          SECTION 3.04 Capitalization.
                       --------------

               (a) The authorized capital stock of the Company consists of
40,000,000 shares of Company Common Stock and 19,500,000 shares of Preferred
Stock, of which 8,200,000 shares are designated as Company Series A Preferred
Stock, 8,000,000 shares are designated as Company Series B Preferred Stock, and
3,300,000 shares are designated as Company Series C Preferred Stock. As of the
date hereof, (i) 11,842,634 shares of Company Common Stock are issued and
outstanding, all of which are duly authorized, validly issued, fully paid and
nonassessable, (ii) no shares of Company Common Stock are held in the treasury
of the Company and (iii) 1,343,274 shares of Company Common Stock are reserved
for future issuance pursuant to outstanding Company Options. As of the date of
this Agreement, (A) 8,173,232 shares of Company Series A Preferred Stock are
issued and outstanding, (B) 7,920,409 shares of Company Series B Preferred Stock
are issued and outstanding, and (C) 3,270,727 shares of Company Series C
Preferred Stock are issued and outstanding, all of which are duly authorized,
validly issued, fully paid and nonassessable. Each share of Company Preferred
Stock is convertible into one share of Company Common Stock. There are no other
shares of Company Preferred Stock outstanding. As of the date hereof, the
outstanding shares of Company Common Stock, Company Series A Preferred Stock,
Company Series B Preferred Stock and Company Series C Preferred Stock are owned
as set forth in Section 3.04(a) of the Company Disclosure Schedule. Section
3.04(a) of the Company Disclosure Schedule also provides an accurate and
complete description of the terms of each repurchase option that is held by the
Company and to which any of such shares is subject. Neither the consummation of
transactions contemplated by this Agreement, nor any action taken or to be taken
by Company in connection with such transactions, will result in (i) any
acceleration of vesting in favor of any stockholder of the Company; (ii) any
additional benefits for any stockholder of the Company (other than as
contemplated by this Agreement); or (iii) the inability of Parent after the
Effective Time to exercise any right or benefit held by Company prior to the
Effective Time with respect to any Company Stock, including, without limitation,
the right to repurchase a stockholder's unvested shares on termination of such
stockholder's employment.

               (b) The Company has reserved 221,668 shares of Company Common
Stock for issuance under the Company's 1999 Equity Incentive Plan (the "1999
                                                                        ----
Equity Incentive Plan"), of which options to purchase 221,668 shares of Company
---------------------
Common Stock are outstanding

                                       10
<PAGE>

as of the date of this Agreement. The Company has reserved 7,265,928 shares of
Company Common Stock for issuance under the Company's 2000 Equity Incentive Plan
(the "2000 Equity Incentive Plan", and together with the 1999 Equity Incentive
      --------------------------
Plan, the "Company Stock Plans"), of which 2,088,594 shares of Company Common
           -------------------
Stock have been issued and are included in the number of issued and outstanding
shares of Company Common Stock set forth in Section 3.04(a) above, and of which
options to purchase 1,121,606 shares of Company Common Stock are outstanding as
of the date of this Agreement. Section 3.04(b) of the Company Disclosure
Schedule accurately sets forth with respect to each Company Option that is
outstanding as of the date of this Agreement: (i) the name of the holder of such
Company Option; (ii) the Company Stock Plan under which such option was granted,
(iii) the total number of shares of Company Common Stock with respect to which
such Company Option is exercisable; (iv) the date on which such Company Option
was granted and the term of such Company Option; (v) the vesting schedule for
such Company Option; (vi) the exercise price per share of Company Common Stock
purchasable under such Company Option; and (vii) whether such Company Option has
been designated an "incentive stock option" as defined in Section 422 of the
Code. No Company Option will by its term require an adjustment in connection
with the Merger (other than as contemplated by this Agreement). Neither the
consummation of transactions contemplated by this Agreement, nor any action
taken or to be taken by Company in connection with such transactions, will
result in (i) any acceleration of vesting in favor of any optionee under any
Company Option; (ii) any additional benefits for any optionee under any Company
Option (other than as contemplated by this Agreement); or (iii) the inability of
Parent after the Effective Time to exercise any right or benefit held by Company
prior to the Effective Time with respect to any Company Option assumed by
Parent, including, without limitation, the right to repurchase an optionee's
unvested shares on termination of such optionee's employment. The assumption by
Parent of Company Options in accordance with Section 2.04 hereunder will not (i)
give the optionees additional benefits that they did not have under their
options prior to such assumption (after taking into account the existing
provisions of the options, such as their respective exercise prices and vesting
schedules) and (ii) constitute a breach of any of the Company Stock Plans or any
agreement entered into pursuant to such plans.

               (c) Except as set forth in Section 3.04(b) of the Company
Disclosure Schedule, there are no options, warrants or other rights, agreements,
arrangements or commitments of any character relating to the issued or unissued
capital stock of the Company or obligating the Company to issue or sell any
share of capital stock of, or other equity interest in, the Company. All shares
of Company Stock so subject to issuance, upon issuance on the terms and
conditions specified in the instruments pursuant to which they are issuable,
will be duly authorized, validly issued, fully paid and nonassessable. There are
no outstanding contractual obligations of the Company to repurchase, redeem or
otherwise acquire any share of capital stock of, or other equity interest in,
the Company. There are no contractual obligations of the Company to provide
funds to, or make any investment in (in the form of a loan, capital contribution
or otherwise), any other person. The holders of Company Options have been or
will be given, or shall have properly waived, any required notice of the Merger
prior thereto, and all such rights, if any, will terminate at or prior to the
Effective Time.

               (d) All of the securities sold or issued by the Company have been
sold or issued in compliance with the requirements of the Federal securities
laws and any applicable state securities or "blue sky" laws.

                                       11
<PAGE>

               (e) Except as set forth in Section 3.04(e) of the Company
Disclosure Schedule, the Company has never repurchased, redeemed or otherwise
reacquired any shares of capital stock or other securities of the Company.

               (f) An updated Section 3.04 of the Company Disclosure Schedule
reflecting changes permitted by this Agreement in the capitalization of Company
between the date hereof and the Effective Time shall be delivered by the Company
to Parent on the Closing Date.

          SECTION 3.05 Authority Relative to This Agreement. (a) The Company has
                       ------------------------------------
all necessary corporate power and authority to execute and deliver this
Agreement and, subject to obtaining the necessary approvals of the Company
Stockholders, to perform its obligations hereunder and to consummate the Merger
and the other transactions contemplated by this Agreement. The execution and
delivery of this Agreement by the Company and the consummation by the Company of
the Merger and the other transactions contemplated by this Agreement have been
duly and validly authorized by all necessary corporate action and no other
corporate proceedings on the part of the Company are necessary to authorize this
Agreement or to consummate the Merger and the other transactions contemplated by
this Agreement (other than, with respect to the Merger, the approval and
adoption of this Agreement by the Company Stockholders as described in Section
3.16 hereof and the filing and recordation of appropriate merger documents as
required by the DGCL). This Agreement has been duly and validly executed and
delivered by the Company and, assuming the due authorization, execution and
delivery by Parent and Merger Sub, constitutes a legal, valid and binding
obligation of the Company, enforceable against the Company in accordance with
its terms, subject to the effect of any applicable bankruptcy, reorganization,
insolvency, moratorium or similar Laws affecting creditors' rights generally and
subject, as to enforceability, to the effect of general principles of equity.

               (b) Without limiting the generality of the foregoing, the Board

          ----                         -----

               (b) Each Plan is in writing and the Company has furnished Parent

programs, arrangements or agreements, whether formal or informal, whether in
writing or not, to which the Company is a party, with respect to which the
Company has any obligation or which are maintained, contributed to or sponsored
by the Company for the benefit of any current or former employee, officer or

to any current or former employee, officer or director of the Company. Each of

Company to pay separation, severance, termination or similar-type benefits
solely or partially as a result of any transaction contemplated by this
Agreement or as a result of a "change in control", within the meaning of such
term under Section 280G of the Code. Neither the execution and delivery of this

alone or together with another event, will (i) result in any payment (including,
without limitation, severance, unemployment compensation, golden parachute,
forgiveness of indebtedness or otherwise) becoming due under any Plan, (ii)
materially increase any benefits otherwise payable under any Plan or other
arrangement, (iii) result in the acceleration of the time of payment, vesting or

respects any Plan's current treatment under any Laws including any tax or social

promised or contracted (whether in oral or written form) to any employee (either
individually or to employees as a group) or any other person that such
employee(s) or other person would be provided with retiree health, except to the
extent required by statute.

               (e) Each Plan is now and always has been operated in all material
respects in accordance with its terms and the requirements of all applicable
Laws, regulations and rules promulgated thereunder including, without
limitation, ERISA and the Code. The Company has performed all obligations
required to be performed by it under, is not in any respect in default under or
in violation of, and has no knowledge of any default or violation by any party
to, any Plan. No action, claim or proceeding is pending or, to the knowledge of
the Company, threatened with respect to any Plan (other than claims for benefits
in the ordinary course) and no fact or event exists that could give rise to any
such action, claim or proceeding. Neither the Company nor any person that is a
member of the same controlled group as the Company or under common control with
the Company within the meaning of Section 414 of the Code (each, an "ERISA
                                                                     -----
Affiliate") is subject to any penalty or Tax with respect to any Plan under
---------
Section 502(i) of ERISA or Sections 4975 through 4980 of the Code. Each Plan

discontinued after the Effective Time, without material liability to the Parent,
Company or any of its ERISA Affiliates (other than ordinary administration
expenses). Neither the Company nor any affiliate has, prior to the Effective
Time and in any material respect, violated any of the health care continuation
requirements of COBRA, the requirements of FMLA, the requirements of the Health
Insurance Portability and Accountability Act of 1996, the requirements of the
Women's Health and Cancer Rights Act of 1998, the requirements of the Newborns'
and Mothers' Health Protection Act of 1996, or any amendment to each such act,
or any similar provisions of state Law applicable to its employees.

               (f) Each Plan intended to qualify under Section 401(a) or Section
401(k) of the Code and each trust intended to qualify under Section 501(a) of
the Code

has either received a favorable determination, opinion, notification or advisory
letter from the IRS with respect to each such Plan as to its qualified status
under the Code, including all amendments to the Code effected by the Tax Reform
Act of 1986 and subsequent legislation, and no fact or event has occurred since
the date of such determination letter or letters from the IRS to adversely
affect the qualified status of any such Plan or the exempt status of any such
trust, or has remaining a period of time under applicable Treasury regulations
or IRS pronouncements in which to apply for such a letter and make any
amendments necessary to obtain a favorable determination as to the qualified
status of each such Plan.

               (g) The Company has not incurred any liability under, arising out
of or by operation of Title IV of ERISA (other than liability for premiums to
the Pension Benefit Guaranty Corporation arising in the ordinary course),
including, without limitation, any liability in connection with (i) the
termination or reorganization of any employee benefit plan subject to Title IV
of ERISA or (ii) the withdrawal from any Multiemployer Plan or Multiple Employer
Plan, and no fact or event exists which could give rise to any such liability.

               (h) All contributions, premiums or payments required to be made
or accrued with respect to any Plan have been made on or before their due dates.
All such contributions have been fully deducted for income tax purposes and no
such deduction has been challenged or disallowed by any Governmental Entity and
no fact or event exists which could give rise to any such challenge or
disallowance.

               (i) Except as set forth in Section 3.11(i) of the Company
Disclosure Schedule, (i) the Company is not a party to any collective bargaining

to Parent. After the date of this Agreement, no material election with respect
to Taxes will be made without the prior written consent of Parent, which consent

joint venture, partnership, or other arrangement or contract which could be
treated as a partnership for Federal income tax purposes. The Company is not
currently and never has been subject to the reporting requirements of Section
6038A of the Code. There is no agreement, contract or arrangement to which the

by reason of the Merger, the Company has not been and will not be required to
include any material adjustment in Taxable income for any Tax period (or portion
thereof) pursuant to Section 481 or 263A of the Code or any comparable provision

accounting methods employed prior to the Merger.

Merger Sub to the Company concurrently with the execution of this Agreement (the

representations or warranties of Parent and Merger Sub specifically referred to

duly incorporated, validly existing and in good standing under the laws of the

The execution and delivery of this Agreement by each of Parent and Merger Sub
and the consummation by each of Parent and Merger Sub of the Merger and the

to any preemptive or other statutory right of stockholders and, will be free of
any lien or encumbrance other than any lien or encumbrance created by or imposed

any material note, bond, mortgage, indenture, contract, agreement, lease,
license, permit, franchise or other instrument or obligation, except, with
respect to clause (iii), for any such conflicts, violations, breaches, defaults,
or other occurrences that could not reasonably be expected, individually or in
the aggregate, to prevent or materially delay the consummation of the
transactions contemplated by this Agreement or to have a Parent Material Adverse
Effect.

                 (b)  The execution and delivery of this Agreement by each of
Parent and Merger Sub do not, and the performance of this Agreement by each of

November 18, 1999 through the date of this Agreement (collectively, the "Parent
                                                                         ------

regulations promulgated thereunder, the "Exchange Act"), as the case may be.
                                         ------------
None of the Parent SEC Documents contained, nor will any forms, reports,
registration statements, proxy statements, prospectuses or other documents filed
after the date of this Agreement and prior to the Effective Time contain, any
untrue statement of a material fact or omit to state a material fact required to
be stated therein or necessary in order to make the statements made therein, in
the light of the circumstances under which they were made, not misleading.
Parent has made all filings required to be made with the SEC and has filed all
documents required to be filed as exhibits to the Parent SEC Documents.

                 (b) Each of the consolidated financial statements (including,
in each case, any notes thereto) contained in the Parent SEC Documents and in

and recurring year-end adjustments that were not and are not expected,
individually or in the aggregate, to have a Parent Material Adverse Effect).

reasonably be expected, if resolved adversely to Parent or Merger Sub, to (i)
have a Parent Material Adverse Effect, (ii) impair the ability of Parent or
Merger Sub to perform its obligations under this Agreement or (iii) prevent,
delay or make illegal the consummation of the transactions contemplated by this
Agreement. To Parent's knowledge, no event has occurred, and no claim, dispute
or other condition or circumstance exists, that could reasonably be expected to
give rise to or serve as a basis of the commencement of any Legal Proceeding of
the types described in (i) through (iii).

     SECTION 4.10 Tax Matters. Neither Parent nor Merger Sub nor any of their
                  -----------

from constituting

<PAGE>

a reorganization qualifying under Section 368(a) of the Code. Parent is not

for-one basis into shares of Company Common Stock in accordance with the
Company's Certificate of Incorporation, and each holder thereof shall have
waived prior notice of the consummation of the Merger;

          (p)  Termination of the Company's Agreements. Parent shall have been
               ---------------------------------------
furnished evidence reasonably satisfactory to it that (i) all co-sale, voting,
registration, first refusal, preemptive, board observation or information rights
granted by the Company to its stockholders and in effect prior to the Closing
shall have terminated as of the Closing and (ii) all of the agreements listed on
Schedule 7.02(p) shall have been terminated prior to the Closing; and

          (q)  Termination of 401(k) Plan. The Company shall have terminated the
               --------------------------
401(k) Plan effective at least one day prior to the Closing Date and no further
contributions shall have been made to the 401(k) Plan. The Company shall have
provided to Parent (i) executed resolutions of the Board of Directors of the
Company authorizing the termination

                                       44
<PAGE>

and (ii) an executed amendment to the 401(k) Plan sufficient to assure
compliance with all applicable requirements of the Code and regulations
thereunder so that the tax-qualified status of the 401(k) Plan will be

          SECTION 7.03 Conditions to the Obligations of the Company. The
                       --------------------------------------------
obligations of the Company to consummate the Merger are subject to the
satisfaction or waiver (where permissible) of the following additional
conditions:

               (a)  Representations and Warranties. Each of the representations
                    ------------------------------
and warranties of Parent and Merger Sub contained in this Agreement that are
qualified as to materiality or Parent Material Adverse Effect, or any similar
standard or qualification, shall be true and correct, and each of the
representations and warranties of Parent and Merger Sub contained in this
Agreement that are not qualified as to materiality or Parent Material Adverse
Effect, or any similar standard or qualification, shall be true and correct in
all material respects, in each case as of the Effective Time, as though made on
and as of the Effective Time, except that those representations and warranties
that address matters only as of a particular date shall remain true and correct
as of such date, and the Company shall have received a certificate of a duly
authorized officer of Parent to such effect;

               (b)  Performance of Covenants. Each of Parent and Merger Sub
                    ------------------------
shall have performed or complied in all material respects with all agreements
and covenants required by this Agreement to be performed or complied with by it
on or prior to the Effective Time, and the Company shall have received a
certificate of a duly authorized officer of Parent to that effect;

               (c)  Opinion of Company's Counsel. The Company shall have
                    ----------------------------
received the opinion of Fenwick & West LLP, counsel to the Company, based upon
representations of Parent, Merger Sub and the Company and normal assumptions, to
the effect that the Merger should be treated for Federal income tax purposes as
a reorganization qualifying under the provisions of Section 368(a) of the Code,
which opinion shall not have been withdrawn or modified in any material respect.
The issuance of such opinion shall be conditioned on receipt by Fenwick & West
LLP of representation letters from each of Parent, Merger Sub and the Company as
contemplated in Section 6.06 of this Agreement. Each such representation letter
shall be dated on or before the date of such opinion and shall not have been
withdrawn or modified in any material respect as of the Effective Time.
Notwithstanding the foregoing, if the Company's counsel does not render such
opinion, this condition shall nevertheless be deemed satisfied with respect to
Company if Gunderson Dettmer, counsel to the Parent, renders such opinion on
behalf of the Company;

               (d)  Opinion of Parent's Counsel. The Company shall have received
                    ---------------------------

reasonably satisfactory to the Company, substantially in the form attached
hereto as Exhibit F; and

               (e)  Listing. If required, the Parent Shares to be issued in the
                    -------
Merger shall have been approved for listing (subject to notice of issuance) on
The Nasdaq National Market.

                       ---------------------------------

          SECTION 8.01 Termination. This Agreement may be terminated and the
                       -----------
Merger and the other transactions contemplated by this Agreement may be
abandoned at any time prior to the Effective Time, notwithstanding any requisite
approval and adoption of this Agreement and the transactions contemplated by
this Agreement, as follows:

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

               (b)  by either Parent or the Company if the Effective Time shall
not have occurred on or before March 31, 2001; provided, however, that the right
                                               --------  -------
to terminate this Agreement under this Section 8.01(b) shall not be available to
any party whose failure to fulfill any obligation under this Agreement has been
the cause of, or resulted in, the failure of the Effective Time to occur on or
before March 31, 2001;

               (c)  by either Parent or the Company, upon the issuance of any
Order that is final and nonappealable which would (i) prevent the consummation
of the Merger or (ii) (A) prohibit Parent's or the Company's ownership or
operation of any portion of the business of the Company or (B) compel Parent or
the Company to dispose of or hold separate, as a result of the Merger, any
portion of the business or assets of the Company or Parent;

               (d)  by Parent upon a breach of any material 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 Sections 7.02(a)
and 7.02(b) would not be satisfied ("Terminating Company Breach"); provided,
                                     --------------------------    --------
however, that, if such Terminating Company Breach is curable by the Company

through the exercise of its best efforts and for so long as the Company
continues to exercise such best efforts, Parent may not terminate this Agreement
under this Section 8.01(d) unless such breach is not cured within 30 days after
notice thereof is provided by Parent to the Company (but no cure period is
required for a breach which, by its nature, cannot be cured); or

               (e)  by the Company upon a breach of any material representation,
warranty, covenant or agreement on the part of Parent and Merger Sub set forth
in this Agreement, or if any representation or warranty of Parent and Merger Sub
shall have become untrue, in either case such that the conditions set forth in
Sections 7.03(a) and 7.03(b) would not be satisfied ("Terminating Parent
                                                      ------------------
Breach"); provided, however, that, if such Terminating Parent Breach is curable
------    --------  -------
by Parent and Merger Sub through the exercise of their respective best efforts
and for so long as Parent and Merger Sub continue to exercise such best efforts,
the Company may not terminate this Agreement under this Section 8.01(e) unless
such breach is not cured within 30 days after notice thereof is provided by the
Company to Parent (but no cure period is required for a breach which, by its
nature, cannot be cured).

          SECTION 8.02 Effect of Termination. In the event of termination of
                       ---------------------
this Agreement pursuant to Section 8.01, this Agreement shall forthwith become
void, there shall be

                                       46
<PAGE>

no liability under this Agreement on the part of Parent, Merger Sub or the
Company or any of their respective officers or directors, and all rights and
obligations of each party hereto shall cease; provided, however, that (i)
                                              --------  -------
Sections 6.02(b) and 6.08 and Articles VIII and IX shall remain in full force
and effect and survive any termination of this Agreement and (ii) nothing herein
shall relieve any party from liability for the breach of any of its
representations, warranties, covenants or agreements set forth in this
Agreement.

          SECTION 8.03 Amendment. This Agreement may be amended by the parties
                       ---------
hereto by action taken by or on behalf of their respective Boards of Directors
at any time prior to the Effective Time. This Agreement may not be amended
except by an instrument in writing signed by the parties hereto.

          SECTION 8.04 Waiver. At any time prior to the Effective Time, any
                       ------
party hereto may (a) extend the time for the performance of any obligation or
other act of any other party hereto, (b) waive any inaccuracy in the
representations and warranties contained herein or in any document delivered
pursuant hereto, and (c) waive compliance with any agreement or condition
contained herein. Any such extension or waiver shall be valid only if set forth
in an instrument in writing signed by the party or parties to be bound thereby.

                                  ARTICLE IX

                                INDEMNIFICATION
                                ---------------

          SECTION 9.01 Survival of Representations and Warranties. The
                       ------------------------------------------
representations and warranties of the Company contained in this Agreement and of
the Company Stockholders in the Voting Agreements shall survive the Effective
Time for a period of 12 months (the "Escrow Period"), whereupon such
                                     -------------
representations and warranties will expire. The representations and warranties
of Parent contained in this Agreement shall survive the Effective Time for a
period of 12 months, whereupon such representations and warranties will expire.
Neither the period of survival nor the liability of a party hereto with respect
to such party's representations and warranties shall be reduced by any
investigation made at any time (whether before or after the Effective Time) by
or on behalf of another party hereto or by any actual, implied or constructive
knowledge or notice of any facts or circumstances that any party may have as a
result of any such investigation or otherwise. If written notice of a claim has
been given prior to the expiration of the applicable representations and
warranties by a party hereto to another party hereto, then the relevant
representations and warranties shall survive as to such claim until such claim
has been finally resolved.

          SECTION 9.02 Indemnification by the Company Stockholders. (a) After
                       -------------------------------------------
the Effective Time, Parent and its affiliates (including, after the Effective
Time, the Surviving Corporation), officers, directors, employees, agents,
successors and assigns (collectively, the "Parent Indemnified Parties") shall be
                                           --------------------------
indemnified and held harmless by the Company Stockholders, jointly and
severally, for any and all liabilities, losses, damages of any kind, diminution
in value, claims, costs, expenses, fines, fees, deficiencies, interest, awards,
judgments, amounts paid in settlement and penalties (including, without
limitation, reasonable attorneys', consultants' and experts' fees and expenses
and other costs of defending, investigating or settling claims) suffered or
incurred by them (including, without limitation, in

                                       47
<PAGE>

connection with any action brought or otherwise initiated by any of them),
reduced by any recovery by Parent actually received under insurance policies
(such reduction to be net of any out-of-pocket expenses, increases in premiums
or any deductible incurred in obtaining such reduction) (hereinafter, a "Loss"),
                                                                         ----
arising out of or resulting from:

               (i)   the breach of any representation or warranty (in each case,
solely for purposes of determining the amount of the Loss resulting from such
breach, and not for determining the existence of a breach, without giving any
effect as to materiality qualifications contained therein) made by the Company
in this Agreement or any Company Stockholder in the Voting Agreements;

               (ii)  the breach of any covenant or agreement made by the Company
in this Agreement or any Company Stockholder in the Voting Agreements; or

               (iii) all costs, fees or expenses incurred by the Company in
connection with this Agreement and the transactions contemplated hereby in
excess of the Aggregate Fees.

          (b)  Notwithstanding anything to the contrary contained in this
Agreement, except with respect to claims based on fraud or willful misconduct:

               (i)   in seeking indemnification for Losses under this Article
IX, the Parent Indemnified Parties shall exercise their remedies solely and
exclusively with respect to the Escrow Shares in the Escrow Fund; provided,
                                                                  --------
however, that no such claim for Losses will be asserted after the expiration of
-------
the Escrow Period;

               (ii)  (A) no Company Stockholder shall have any liability to a
Parent Indemnified Party under this Agreement or the Voting Agreements except to
the extent of the Escrow Shares attributable to such Company Stockholder and (B)
the remedies set forth in this Article IX shall be the exclusive remedies of
Parent and the other Parent Indemnified Parties hereunder against any Company
Stockholder; and

               (iii) no indemnification payment by the Company Stockholders with
respect to any indemnifiable Loss otherwise payable under Section 9.02(a) and
arising out of or resulting from the causes enumerated in Section 9.02(a)(i)
shall be payable until such time as all such indemnifiable Losses shall
aggregate to more than $400,000, after which time the Company Stockholders shall
be liable in full for all indemnifiable Losses (including the first $400,000);
provided, however, that the limitations set forth above in this clause (iii)
--------  -------
shall not be operative with respect to Losses arising from breaches of any of
the representations and warranties set forth in Sections 3.01, 3.02, 3.03, 3.04,
3.05, 3.06, 3.13, 3.15, 3.16 and 3.20.

          (c)  The parties agree that any payment required to be made by Parent
to compensate the Company Stockholders for any Loss incurred by such Company
Stockholder as a result of a breach by Parent or Merger Sub of any of its
representations and warranties in this Agreement shall be paid in cash;
provided, however, that in no event shall cash be paid to the extent that such
--------  -------
payment or portion of such payment, when aggregated with any other payments made
for Losses pursuant to this Article IX and other non-stock consideration paid to
the Company Stockholders (including, without limitation, cash paid for
fractional shares and

                                       48
<PAGE>

Dissenting Shares, if any) would equal or exceed an amount such that the Parent
Common Stock would constitute less than eighty percent (80%) of total Merger
consideration (including payments for Losses pursuant to this Article IX). Any
such excess shall be paid in shares of Parent Common Stock, which shall be
valued by dividing the dollar amount of the Loss by the average closing price
per share of Parent Common Stock on The Nasdaq National Market for the thirty
consecutive trading days immediately preceding the date of the determination by
a court or arbitrator having competent jurisdiction over the matters relating to
the claim (or the date of the written instructions or deemed acknowledgment of
the claim by Parent, as the case may be, if no such determination is obtained)
as to the amount of any claim for indemnification.

          SECTION 9.03 Indemnification Procedures. (a) For purposes of this
                       --------------------------
Section 9.03, a party against which indemnification may be sought is referred to
as the "Indemnifying Party" and the party which may be entitled to
        ------------------
indemnification is referred to as the "Indemnified Party."
                                       -----------------

               (b)  The obligations and liabilities of Indemnifying Parties
under this Article IX with respect to Losses arising from claims of any third
party that are subject to the indemnification provided for in this Article IX
("Third Party Claims") shall be governed by and contingent upon the following
  ------------------
additional terms and conditions: if an Indemnified Party shall receive notice of
any Third Party Claim, the Indemnified Party shall give all Indemnifying Parties
notice of such Third Party Claim within 30 days of the receipt by the
Indemnified Party of such notice; provided, however, that the failure to provide
                                  --------  -------
such notice shall not release an Indemnifying Party from any of its obligations
under this Article IX except to the extent that such Indemnifying Party is
materially prejudiced by such failure. The notice of claim shall describe in
reasonable detail the facts known to the Indemnified Party giving rise to such
indemnification claim, and the amount or good faith estimate of the amount
arising therefrom.

               (c)  If the Indemnifying Party acknowledges in writing its
obligation to indemnify the Indemnified Party hereunder against any Losses that
may result from such Third Party Claim, and (i) Parent has reasonably determined
that Losses that may be incurred as a result of the Third Party Claim do not
exceed individually, or when aggregated with all other Losses subject to
indemnification under Section 9.02, the maximum aggregate amount of
indemnifiable Losses set forth in such sections, (ii) the Third Party Claim
involves only money damages and does not seek an injunction or other equitable
remedy, and (iii) settlement of, or an adverse judgment with respect to, the
Third Party Claim is not, in the good faith judgment of Parent, likely to
establish a precedential custom or practice adverse to the continuing business
interests of Parent or to increase the Tax liability of Parent or the Company,
then the Indemnifying Party shall be entitled to assume and control the defense
of such Third Party Claim at its expense and through counsel of its choice (such
counsel to be reasonably acceptable to Parent) if it gives notice of its
intention to do so to the Indemnified Party within 10 days of the receipt of
such notice from the Indemnified Party; provided, however, that, if there exists
                                        --------  -------
or is reasonably likely to exist a conflict of interest that would make it
inappropriate in the judgment of the Indemnified Party, in its reasonable
discretion, for the same counsel to represent both the Indemnified Party and the
Indemnifying Party, then the Indemnified Party shall be entitled to retain its
own counsel, in each jurisdiction for which the Indemnified Party determines
counsel is required, at the expense of the Indemnifying Party. In the event that
the Indemnifying Party exercises the right to undertake any such defense against
any such Third Party Claim as provided

                                       49
<PAGE>

above, the Indemnifying Party shall conduct the defense of the Third Party Claim
actively and diligently and the Indemnified Party shall cooperate with the
Indemnifying Party in such defense and make available to the Indemnifying Party,
at the Indemnifying Party's expense, all witnesses, pertinent records, materials
and information in the Indemnified Party's possession or under the Indemnified
Party's control relating thereto as is reasonably requested by the Indemnifying
Party. Similarly, in the event the Indemnified Party is, directly or indirectly,
conducting the defense against any such Third Party Claim, the Indemnifying
Party shall cooperate with the Indemnified Party in such defense and make
available to the Indemnified Party, at the Indemnifying Party's expense, all
such witnesses, records, materials and information in the Indemnifying Party's
possession or under the Indemnifying Party's control relating thereto as is
reasonably requested by the Indemnified Party. No such Third Party Claim may be
settled by any party conducting the defense against such claim without the prior
written consent of the other party unless the other party and its affiliates are
released in full in connection with such settlement and no admission of
liability is involved; provided, however, if the Company Stockholders are not
entitled to assume the defense against such Third Party Claim pursuant to this
paragraph, the Parent Indemnified Party shall have the right to consent to the
entry of any judgment or enter into any settlement with respect to the Third
Party Claim in any manner it may deem appropriate (and the Parent need not
consult with, or obtain any consent from, the Company Stockholders or the
Stockholders' Representative in connection therewith).

          SECTION 9.04 Stockholders' Representative. John Scharber (such person
                       ----------------------------
and any successor or successors being the "Stockholders' Representative") shall
                                           ----------------------------
act as the representative of the Company Stockholders, and shall be authorized
to act on behalf of the Company Stockholders and to take any and all actions
required or permitted to be taken by the Stockholders' Representative under this
Agreement or the Escrow Agreement, with respect to any claims (including the
settlement thereof) for indemnification from the Escrow Fund made by Parent
pursuant to this Article IX and with respect to any actions to be taken by the
Stockholders' Representative pursuant to the terms of the Escrow Agreement
(including, without limitation, the exercise of the power to: authorize delivery
to Parent of Escrow Shares in satisfaction of claims by Parent; agree to,
negotiate, enter into settlements and compromises, demand arbitration, and
comply with orders of courts and awards of arbitrators with respect to such
claims; and take all actions necessary in the judgment of the Stockholders'
Representative for the accomplishment of the foregoing). The Company
Stockholders shall be bound by all actions taken by the Stockholders'
Representative in its capacity thereof, except for any action that conflicts
with the limitations set forth in Section 9.02(b)(ii) or (iii) or the final
sentence of this Section 9.04. The Stockholders' Representative shall promptly,
and in any event within five business days, provide written notice to the
Company Stockholders of any action taken on behalf of them by the Stockholders'
Representative pursuant to the authority delegated to the Stockholders'
Representative under this Section 9.04. The Stockholders' Representative shall
at all times act in his or her capacity as Stockholders' Representative in a
manner that the Stockholders' Representative believes to be in the best interest
of the Company Stockholders. Neither the Stockholders' Representative nor any of
its directors, officers, agents or employees shall be liable to any person for
any error of judgment, or any action taken, suffered or omitted to be taken,
under this Agreement or the Escrow Agreement, except in the case of its gross
negligence, bad faith or willful misconduct. The Stockholders' Representative
may consult with legal counsel, independent public accountants and other experts
selected by it and shall not be liable for any action taken or omitted to be
taken in good faith by it in accordance with the

                                       50
<PAGE>

advice of such counsel, accountants or experts. The Stockholders' Representative
shall not have any duty to ascertain or to inquire as to the performance or
observance of any of the terms, covenants or conditions of this Agreement or the
Escrow Agreement. As to any matters not expressly provided for in this Agreement
or the Escrow Agreement, the Stockholders' Representative shall not exercise any
discretion or take any action. Each Company Stockholder severally shall
indemnify and hold harmless and reimburse the Stockholders' Representative from
and against such Company Stockholder's ratable share of any and all liabilities,
losses, damages, claims, costs or expenses suffered or incurred by the
Stockholders' Representative arising out of or resulting from any action taken
or omitted to be taken by the Stockholders' Representative under this Agreement
or the Escrow Agreement, other than such liabilities, losses, damages, claims,
costs or expenses arising out of or resulting from the Stockholders'
Representative's gross negligence, bad faith or willful misconduct. In all
matters relating to claims for indemnification from the Escrow Fund under this
Article IX, the Stockholders' Representative shall be the only party entitled to
assert the rights of the Company Stockholders, and the Stockholders'
Representative shall perform all of the obligations of the Company Stockholders
hereunder. Parent shall be entitled to rely on all statements, representations
and decisions of the Stockholders' Representative with respect to such claims.
