ITEM 2.  ACQUISITION OR DISPOSITION OF ASSETS

              On June 30, 1998, and effective on that date, The Vantive
Corporation (the "Company") completed an acquisition (the "Merger") of Wayfarer
Communications, Inc., a privately-held California corporation ("Wayfarer"),
pursuant to an Agreement and Plan of Reorganization, dated June 18, 1998, by and
between the Company, Revo Acquisition Corporation, a wholly-owned subsidiary of
the Company, and Wayfarer. Upon consummation of the Merger, Wayfarer became a
wholly-owned subsidiary of the Company.

              Under the terms of the Merger, Wayfarer's securityholders will
receive approximately 179,000 shares of the Company's Common Stock in exchange
for all outstanding shares of Wayfarer capital stock. The transaction will be
accounted for as a purchase. Vantive expects to record charges related to the
acquisition of approximately $11.5 million in the second quarter of 1998,
including a one-time in-process research and development charge and a
compensatory bonus expense.

              The amount of the Merger consideration was determined through
arms-length negotiation. There were no material relationships between the
Wayfarer shareholders and the Company or any of its affiliates, any director or
officer of the Company, or any associate of any such director or officer prior
to the Merger. The Company is obligated to prepare and file with the Securities
and Exchange Commission a registration statement on Form S-3 with respect to the
shares of the Company's Common Stock issued in the Merger.

                                    Recitals

        WHEREAS, the Boards of Directors of Buyer, Sub and Target deem it
advisable and in the best interests of each corporation and its respective
shareholders that Buyer and Target combine in order to advance the long-term
business interests of Buyer and Target;

        WHEREAS, the combination of Buyer and Target shall be effected by the
terms of this Agreement through a transaction in which Sub will merge with and
into Target, Target will become a wholly-owned subsidiary of Buyer and the
shareholders of Target will become stockholders of Buyer; and

        WHEREAS, for federal income tax purposes, the parties to this Agreement
intend, by approving resolutions authorizing this Agreement, to adopt this
Agreement as a plan of reorganization within the meaning of Section 368(a) of
the Internal Revenue Code of 1986, as amended (the "Code"), and the regulations
thereunder, and that the merger of Sub with and into Target shall qualify as a
reorganization within the meaning of Section 368(a) of the Code.

        NOW, THEREFORE, in consideration of the foregoing and the respective
representations, warranties, covenants and agreements set forth below, the
parties agree as follows:

                                    ARTICLE I

officers of the Surviving Corporation and shall hold office in accordance with
the Articles of Incorporation and Bylaws of the Surviving Corporation, in each
case until their respective successors are duly elected or appointed.

                                   ARTICLE II

                 CONVERSION OF SECURITIES; MERGER CONSIDERATION

        Section 2.1 Conversion of Capital Stock. As of the Effective Time, by
virtue of the Merger and without any action on the part of Buyer, Sub, Target or
the holder of any shares of common stock, no par value per share, of Target
("Target Common Stock") or capital stock of Sub:


                                       2
<PAGE>   7

               (a) Capital Stock of Sub. Each issued and outstanding share of
the capital stock of Sub shall be converted into and become one fully paid and
nonassessable share of common stock, $0.001 par value, of the Surviving
Corporation.

               (b) Cancellation of Treasury Shares and Buyer-Owned Stock. All
shares of Target Common Stock and/or shares of preferred stock, no par value per
share, of Target ("Target Preferred Stock" and, collectively with Target Common
Stock, "Target Stock") owned by Target as treasury shares or by Buyer, Sub or
any other wholly-owned subsidiary of Buyer shall be canceled and retired and
shall cease to exist, and no stock of Buyer or other consideration shall be
delivered in exchange therefor.

               (c) Exchange Ratios for Target Stock. Subject to Section 2.2, all
shares of Target Stock shall be converted as follows:

                   (i) Target Common Stock. Each issued and outstanding share of
Target Common Stock (other than shares canceled in accordance with Section
2.1(b) and Dissenting Shares as defined in Section 2.1(e)) shall be converted
into the right to receive 0.0006262 fully paid and nonassessable shares of
common stock, $0.001 par value, of Buyer ("Buyer Common Stock"). The foregoing
conversion ratio shall be subject to adjustment to reflect any stock split or
stock dividend with respect to Target Common Stock effected between the date of
this Agreement and the Effective Time.

                   (ii) Target Preferred Stock. Each issued and outstanding
share of Target Preferred Stock (other than shares canceled in accordance with
Section 2.1(b) and Dissenting Shares as defined in Section 2.1(e)) shall be
converted into the right to receive that number of shares of fully paid and
nonassessable Buyer Common Stock equal to the quotient obtained by dividing (A)
the Pool of Shares (as defined below) for such share's series, by (B) the total
number of then issued and outstanding shares of Target Preferred Stock in such
series and the number of shares of such series subject to then outstanding
warrants, with the quotient thereby obtained carried to seven (7) decimal
places. The foregoing conversion ratios shall be subject to the Post-Closing
Adjustment (as defined in Section 2.4(a)) and to adjustment to reflect any stock
split or stock dividend with respect to such series of Target Preferred Stock
effected between the date of this Agreement and the Effective Time.

                   (iii) Definition of "Pool of Shares" for Each Series of
Target Preferred Stock. The "Pool of Shares" with respect to each series of
Target Preferred Stock shall mean the product of (A) 178,603 shares of Buyer
Common Stock (which number of shares is calculated as set forth in Annex
2.1(c)(iii)) and (B) the ratio of the aggregate dollar liquidation preference of
such series (including outstanding shares and shares subject to outstanding
warrants) as set forth in the Articles of Incorporation of Target to the
aggregate dollar liquidation preference of all series of Target Preferred Stock
(including outstanding shares and shares subject to outstanding warrants) as set
forth in the Articles of Incorporation of Target (the product thereby obtained
carried to four (4) decimal places).

All such shares of Target Common Stock and Target Preferred Stock, when so
converted, shall no longer be outstanding and shall automatically be canceled
and retired and shall cease to 


                                       3
<PAGE>   8

exist, and each holder of a certificate representing any such shares shall cease
to have any rights with respect thereto, except the right to receive the shares
of Buyer Common Stock to be issued in consideration therefor upon the surrender
of such certificate in accordance with this Article II.

               (d) Target Options and Warrants. At the Effective Time, (i) all
then outstanding options to purchase Target Common Stock ("Target Options") will
be canceled by Target in accordance with the provisions of Section 6.12 and (ii)
all then outstanding warrants to purchase Target Stock (the "Target Warrants")
will be assumed by Buyer in accordance with the provisions of Section 6.13.

               (e) Dissenters' Rights. Any shares of Target Stock held by
shareholders of Target who properly exercise and perfect the dissenters'
appraisal rights set forth in Chapter 13 of the GCL ("Dissenting Shares") shall
not be converted into the right to receive Buyer Common Stock but shall instead
be converted into the right to receive such consideration as may be determined
to be due with respect to such Dissenting Shares pursuant to the provisions of
the GCL. Target shall give Buyer prompt notice of any demand received by Target
for appraisal of Target Stock, and Buyer shall have the right to control all
negotiations and proceedings with respect to such demand. Target agrees that,
except with the prior written consent of Buyer or as required under the GCL, it
will not voluntarily make any payment with respect to, or settle or offer to
settle, any such demand for appraisal. Each holder of Dissenting Shares (a
"Dissenting Shareholder") who, pursuant to the provisions of the GCL, becomes
entitled to payment of the value of shares of Target Stock shall receive payment
therefor (but only after the value therefor shall have been agreed upon or
finally determined pursuant to the provisions of the GCL). In the event that any
holder of shares of Target Stock fails to make an effective demand for payment
or otherwise loses his or her status as a Dissenting Shareholder, that holder
shall thereafter be entitled to the same rights to receive Buyer Common Stock
and any cash payment in lieu of fractional shares, in each case without interest
thereon, to which such Dissenting Shareholder would have been entitled to under
Section 2.1 and the Merger Agreement.

               (f) Certificate Legends. The shares of Buyer Common Stock to be
issued pursuant to this Article II shall not have been registered and shall be
characterized as "restricted securities" under the federal securities laws, and
under such laws such shares may be resold without registration under the
Securities Act of 1933, as amended (the "Securities Act"), only in certain
limited circumstances. Each certificate evidencing shares of Buyer Common Stock
to be issued pursuant to this Article II shall bear the following legend:

        "THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE BEEN
        ACQUIRED FOR INVESTMENT AND HAVE NOT BEEN REGISTERED UNDER
        THE SECURITIES ACT OF 1933. SUCH SHARES MAY NOT BE SOLD OR
        OTHERWISE TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION
        WITHOUT AN EXEMPTION UNDER THE SECURITIES ACT OR AN OPINION
        OF LEGAL COUNSEL REASONABLY ACCEPTABLE TO THE COMPANY THAT
        SUCH REGISTRATION IS NOT REQUIRED."

        Section 2.2 Exchange of Certificates. The procedures for exchanging
outstanding shares of Target Common Stock and Target Preferred Stock for Buyer
Common Stock pursuant to the Merger are as follows:

               (a) Exchange Agent. Promptly after the Effective Time, Buyer
shall deposit with an exchange agent designated by Buyer (the "Exchange Agent"),
for the benefit of the holders of shares of Target Stock, for exchange in
accordance with this Section 2.2, through the Exchange Agent, certificates
representing the shares of Buyer Common Stock issuable pursuant to Section 2.1,
less the Escrow Shares (as defined in Section 2.3). The shares of Buyer Common
Stock deposited with the Exchange Agent, together with any dividends or
distributions with respect thereto, hereinafter shall be referred to as the
"Exchange Fund."

               (b) Exchange Procedures. As soon as reasonably practicable after
the Effective Time, the Exchange Agent shall mail to each holder of record of a
certificate that immediately prior to the Effective Time represented outstanding
shares of Target Stock (a "Target Certificate") (i) a letter of transmittal
(which shall specify that delivery shall be effected, and risk of loss and title
to the Target Certificates shall pass, only upon delivery of the Target
Certificates to the Exchange Agent and shall be in such form and have such other
provisions as Buyer and Target may reasonably specify) and (ii) instructions for
use in effecting the surrender of the Target Certificates in exchange for
certificates representing shares of Buyer Common Stock ("Buyer Certificates").
Upon surrender of a Target Certificate for cancellation to the Exchange Agent
(or such other agent or agents as may be appointed by Buyer), together with a
duly executed letter of transmittal, the holder of such Target Certificate shall
be entitled to receive in exchange therefor a Buyer Certificate representing
that number of whole shares of Buyer Common Stock which such holder has the
right to receive pursuant to the provisions of Section 2.1(c) less such
shareholder's pro rata portion of the Escrow Shares, and the Target Certificate
so surrendered shall immediately be canceled. If any Target Certificate shall
have been lost, stolen or destroyed, Buyer may, in its reasonable discretion and
as a condition precedent to the issuance of any certificate representing Buyer
Common Stock, require the owner of such lost, stolen or destroyed Target
Certificate to provide an appropriate affidavit and to deliver a bond (in such
sum as Buyer may reasonably direct) as indemnity against any claim that may be
made against Buyer or the Surviving Corporation with respect to such Target
Certificate (such affidavit and bond, if required, together an "Acceptable
Affidavit"). In the event of a transfer of ownership of Target Stock which is
not registered in the transfer records of Target, a Buyer Certificate
representing the proper number of shares of Buyer Common Stock may be issued to
a transferee if the Target Certificate representing such Target Stock is
presented to the Exchange Agent, accompanied by all documents reasonably
required to evidence and effect such transfer and by evidence that any
applicable stock transfer taxes have been paid. Until surrendered as
contemplated by this Section 2.2, each Target Certificate shall be deemed at any
time after the Effective Time to represent only the right to receive upon such
surrender a Buyer Certificate as contemplated by this Agreement.

               (c) Distributions with Respect to Unexchanged Shares. No
dividends or other distributions declared or made after the Effective Time with
respect to Buyer Common Stock with a record date after the Effective Time shall
be paid to the holder of any unsurrendered


                                       5
<PAGE>   10

Target Certificate with respect to the shares of Buyer Common Stock represented
thereby until the holder of record of such Target Certificate shall surrender
such Target Certificate or, in the case of a lost, stolen or destroyed Target
Certificate, an Acceptable Affidavit. Subject to the effect of applicable laws,
following surrender of any such Target Certificate or Acceptable Affidavit,
there shall be paid to the record holder of the Buyer Certificates issued in
exchange therefor, without interest, (i) the amount of dividends or other
distributions with a record date after the Effective Time previously paid with
respect to such whole shares of Buyer Common Stock, and (ii) at the appropriate
payment date, the amount of dividends or other distributions with a record date
after the Effective Time but prior to surrender and a payment date subsequent to
surrender payable with respect to such whole shares of Buyer Common Stock.

               (d) No Further Ownership Rights in Target Stock. All shares of
Buyer Common Stock issued upon the surrender for exchange of shares of Target
Stock in accordance with the terms hereof (including any cash paid pursuant to
subsection (c) of this Section 2.2) shall be deemed to have been issued in full
satisfaction of all rights pertaining to such shares of Target Stock, and there
shall be no further registration of transfers on the stock transfer books of the
Surviving Corporation of the shares of Target Stock which were outstanding
immediately prior to the Effective Time. If, after the Effective Time, Target
Certificates or Acceptable Affidavits are presented to Buyer or the Surviving
Corporation for any reason, they shall be canceled and exchanged as provided in
this Section 2.2.

               (e) No Fractional Shares. No certificate or scrip representing
fractional shares of Buyer Common Stock shall be issued upon the surrender for
exchange of Target Certificates, and such fractional share interests will not
entitle the owner thereof to vote or to any rights of a shareholder of Buyer.
Notwithstanding any other provision of this Agreement, (i) the number of shares
to be issued to each holder of shares of Target Common Stock exchanged pursuant
to the Merger who would otherwise have been entitled to receive a fraction of a
share of Buyer Common Stock shall be rounded up to the nearest whole share and
(ii) the number of shares to be issued to each holder of Target Preferred Stock
exchanged pursuant to the Merger who would otherwise have been entitled to
receive a fraction of a share of Buyer Common Stock shall be rounded to the
nearest whole integer.

               (f) Termination of Exchange Fund. Any portion of the Exchange
Fund which remains undistributed to the shareholders of Target one year after
the Effective Time shall be delivered to Buyer, upon demand, and any
shareholders of Target who have not previously complied with this Section 2.2
shall thereafter look only to Buyer for payment of their claim for Buyer Common
Stock and any dividends or distributions with respect to Buyer Common Stock.

               (g) No Liability. Neither Buyer nor Target shall be liable to any
holder of shares of Target Stock or Buyer Common Stock, as the case may be, for
such shares (or dividends or distributions with respect thereto) delivered to a
public official pursuant to any applicable abandoned property, escheat or
similar law.

        Section 2.3 Escrow. At the Closing, Buyer will deduct from the number of
shares of Buyer Common Stock deliverable to the holders of Target Preferred
Stock (whether or not such 


                                       6
<PAGE>   11

holders also hold Target Common Stock) pursuant to Section 2.2(b), and will
deposit into escrow (the "Escrow") a certificate representing twenty-five
percent (25%) of the shares of Buyer Common Stock issuable in the Merger to such
holders with respect to the shares of Target Preferred Stock, on a pro rata
basis, rounded down to the nearest whole share (the "Escrow Shares"). The Escrow
Shares shall be held by Harris Trust and Savings Bank (or such other institution
as shall be agreed upon by Buyer and the Shareholder Representative (as defined
in Section 9.7)) as escrow agent (the "Escrow Agent"), in accordance with and
subject to the provisions of an Escrow Agreement substantially in the form of
Annex 2.3 (the "Escrow Agreement"). The Escrow Shares shall be held as (i) a
fund from which the Post-Closing Adjustment (as defined in Section 2.4(a)) may
be deducted and (ii) collateral for the indemnification obligations under
Article IX of the persons who were holders of Target Preferred Stock immediately
prior to the Effective Time.




        Section 2.4 Calculation and Payment of Post-Closing Adjustment.

               (a) Signing Date Balance Sheet, Closing Date Balance Sheet and
Liabilities Certificate. As soon as practicable, and no later than fifteen (15)
days following the Effective Date, the Shareholder Representative, on behalf of
the former Target shareholders, shall cause to be prepared and shall furnish to
Buyer (i) a balance sheet of Target as of the date hereof (the "Signing Date
Balance Sheet") and (ii) a balance sheet of Target as of the Closing Date (the
"Closing Date Balance Sheet"). The Signing Date Balance Sheet and the Closing
Date Balance Sheet shall be prepared in accordance with generally accepted
accounting principals ("GAAP") applied on a consistent basis, except for the
absence of required footnotes, and shall be certified by the persons who
immediately prior to the Effective Time served as the President and Chief
Financial Officer of Target, each in their respective official capacity. The
Signing Date Balance Sheet and the Closing Date Balance Sheet shall be
accompanied by a certificate, certified by such persons (the "Liabilities
Certificate"), setting forth (i) a detailed schedule of all liabilities of
Target reflected on the Signing Date Balance Sheet, and (ii) a calculation of
the "Post-Closing Adjustment" which shall be the amount by which $4,675,000 is
exceeded by the amount of the liabilities of Target reflected on the Signing
Date Balance Sheet, including, without limitation, "Target's Management Bonus
Obligation" which shall be the amount on Annex 2.4(a), and Target Transaction
Expenses (as defined in Section 6.16) but excluding (A) any deferred liabilities
relating to deferred revenue generated by Target's dealings with Sumitomo
Corporation and Targetvision Inc., and (B) financial advisory fees of $225,000
included in the Target Transaction Expenses. Buyer and the Surviving Corporation
shall afford the Shareholder Representative and Target's accountants access to
Target's books and records for the purpose of preparing the Signing Date Balance
Sheet, the Closing Date Balance Sheet and the Liabilities Certificate and
calculating the Post-Closing Adjustment.

               (b) Buyer's Review and Approval. Buyer shall have fifteen (15)
days after receipt of the Signing Date Balance Sheet, the Closing Date Balance
Sheet and the Liabilities Certificate in which to give the Shareholder
Representative written notice of any objection 


                                       7
<PAGE>   12

(which notice shall specify the factual basis of such objection and the amount
at issue) to the Signing Date Balance Sheet, the Closing Date Balance Sheet, the
Liabilities Certificate or the proposed Post-Closing Adjustment. If Buyer does
not timely object, the Shareholder Representative's proposed Post-Closing
Adjustment shall be deemed to be binding on the parties for purposes of this
Section 2.4.

               (c) Dispute Resolution. If Buyer timely objects to the Signing
Date Balance Sheet, the Liabilities Certificate or the Shareholder
Representative's proposed Post-Closing Adjustment, the Shareholder
Representative shall promptly meet with Buyer and attempt in good faith to reach
a resolution of such disagreement. Any such dispute which is not resolved by the
Shareholder Representative and Buyer and their respective accountants within
fifteen (15) days after delivery of notice of the dispute by Buyer shall, upon
written request of either the Shareholder Representative or Buyer delivered to
the other party, be submitted for final resolution to an independent certified
public accounting firm of national reputation selected jointly by Buyer's
independent certified public accountants and an independent certified public
accounting firm designated by the Shareholder Representative. Each party shall,
within five (5) business days after submission of such dispute, deliver to such
accounting firm the information such party wishes to have considered by such
firm in making its determination. Such accounting firm shall present its
determination or resolution of any dispute within fifteen (15) days after
submission of such dispute to the firm. The determination of the Post-Closing
Adjustment by such accounting firm shall be binding on the parties for purposes
of this Section 2.4. The fees of such accounting firm shall be borne by the
party whose position in the dispute with respect to the calculation of the
Post-Closing Adjustment is furthest from the final Post-Closing Adjustment as
determined by such accounting firm. Any such fees to be borne by Target shall
constitute Target Transaction Expenses and shall be added to the Post-Closing
Adjustment.

               (d) Post-Closing Adjustment. Within five (5) business days
following the determination of the Post-Closing Adjustment pursuant to Section
2.4(b) or 2.4(c), Buyer and the Shareholder Representative shall direct the
Escrow Agent to deliver out of the Escrow to Buyer the number of shares of Buyer
Common Stock determined by dividing the amount of the Post-Closing Adjustment by
$31.9375.

               (e) Effect on Rights of Buyer. No acceptance by Buyer of the
Closing Date Balance Sheet or the Liabilities Certificate or any determination
of the Post-Closing Adjustment for purposes of this Section 2.4 shall constitute
a waiver of any inaccuracies in the representations or warranties of Target
contained in this Agreement or limit in any way Buyer's right to assert claims
for indemnification pursuant to Article IX, except with respect to any claim(s)
relating to the amount of, or requiring adjustment of, the Post-Closing
Adjustment.

                                   ARTICLE III

                    REPRESENTATIONS AND WARRANTIES OF TARGET

        Except as set forth in the disclosure schedule (which disclosure
schedule shall be organized into numbered sections corresponding with the
section numbers of this Agreement) delivered by Target to Buyer on or before the
date of this Agreement and attached hereto as Annex 3 (the "Target Disclosure
Schedule"), Target represents and warrants to Buyer as follows:

        Section 3.1 Organization, Standing and Power; Qualification;
Subsidiaries. Target is a corporation duly organized, validly existing and in
good standing under the laws of the State of California; has all requisite
corporate power to own, lease and operate its properties and to carry on its
business as currently being conducted and as currently proposed to be conducted;
is duly qualified to do business and is in good standing in each jurisdiction in
which the failure to be so qualified and in good standing would have a material
adverse effect on the business, assets (including intangible assets),
properties, liabilities (contingent or otherwise), financial condition,
operations, or results of operation (a "Material Adverse Effect") of Target; and
Target does not directly or indirectly own any equity or similar interest in, or
any interest convertible or exchangeable or exercisable for any equity or
similar interest in, any corporation, partnership, joint venture or other
business association or entity. Target has delivered true and correct copies of
the Articles of Incorporation and Bylaws of Target, each as amended to date, to
Buyer. Target is not in violation of any of the provisions of its Articles of
Incorporation or Bylaws.



        Section 3.2 Target Capital Structure.

               (a) The authorized capital stock of Target consists of (i)
20,000,000 shares of Target Common Stock, of which 3,516,954 shares are issued
and outstanding and (ii) 8,801,708 shares of Target Preferred Stock, no par
value, of which: (A) 800,000 shares are designated as Series A Preferred Stock,
all 800,000 of which are issued and outstanding; (B) 400,000 shares are
designated as Series C Preferred Stock, all 400,000 of which are issued and
outstanding; (C) 2,161,308 shares are designated as Series D Preferred Stock,
2,142,308 of which are issued and outstanding; (D) 1,576,800 shares are

outstanding; and (E) 3,520,000 shares are designated as Series F Preferred
Stock, 2,100,844 of which are issued and outstanding. The outstanding Target
Stock is held of record by those persons set forth in Section 3.2 of the Target
Disclosure Schedule (which list sets forth the amount of Target Common Stock and
Target Preferred Stock held by each such person and/or entity). All outstanding
shares of Target Common Stock and Target Preferred Stock have been duly
authorized and validly issued, are fully paid and nonassessable, were issued in
compliance with state and federal securities laws, and are subject to no
preemptive rights or rights of first refusal created by statute, the Articles of
Incorporation or Bylaws of Target or any agreement to which Target is a party or
by which it is bound.


                                       9
<PAGE>   14

               (b) Except as set forth in Section 3.2(a) or Section 3.2 of the
Target Disclosure Schedule, and except for the conversion rights of the holders
of the outstanding Target Preferred Stock, there are (i) no equity securities of
any class of Target or any securities exchangeable into or exercisable for such
equity securities issued, reserved for issuance, or outstanding and (ii) no
outstanding subscriptions, options, warrants, puts, calls, rights, or other
commitments or agreements of any character to which Target is a party or by
which it is bound obligating Target to issue, deliver, sell, repurchase or
redeem, or cause to be issued, delivered, sold, repurchased or redeemed, any
equity securities of Target or obligating Target to grant, extend, accelerate
the vesting of, change the price of, or otherwise amend or enter into any such
option, warrant, call, right, commitment or agreement. Section 3.2 of the Target
Disclosure Schedule sets forth the names of all holders of Target Options and
Target Warrants, together with the number of shares of Target Stock for which
each such option and warrant may be exercised, and the exercise price and
vesting schedule (including acceleration provisions, if any) for each such
option and warrant. There are no contracts, commitments or agreements relating
to voting, purchase or sale of Target capital stock (i) between or among Target
and any of its shareholders or the holders of any Target Options or Target
Warrants, or (ii) to Target's knowledge, between or among any Target
shareholders or the holders of any Target Options or Target Warrants.

        Section 3.3 Authority; No Conflict; Required Filings and Consents.

               (a) Target has all requisite corporate power and authority to
enter into this Agreement and the other documents required to be executed and
delivered by Target hereunder, including the Merger Agreement (collectively, the
"Target Transaction Documents"), and to consummate the transactions contemplated
hereby and thereby. The execution and delivery of this Agreement and the other
Target Transaction Documents and the consummation of the transactions
contemplated hereby and thereby have been duly authorized by all necessary
corporate action on the part of Target, subject only to the approval of the
Merger by Target's shareholders in accordance with the GCL. This Agreement and
the other Target Transaction Documents have been duly executed and delivered by
Target and constitute the valid and binding obligations of Target, enforceable
against Target in accordance with their respective terms, except as such
enforceability may be limited (i) by bankruptcy, insolvency, moratorium or other
similar laws affecting or relating to creditors' rights generally and (ii)
general principles of equity, regardless of whether asserted in a proceeding in
equity or at law and except for the need for Target to obtain shareholder
approval for the Merger.

               (b) The execution and delivery by Target of this Agreement and
the other Target Transaction Documents do not, and the consummation of the
transactions contemplated hereby and thereby will not, (i) conflict with, or
result in any violation or breach of any provision of the Articles of
Incorporation or Bylaws of Target, (ii) result in any violation or breach of, or
constitute (with or without notice or lapse of time, or both) a default under,
or give rise to a right of termination, cancellation or acceleration of any
material obligation or loss of any material benefit under, any note, bond,
mortgage, indenture, lease, contract or other agreement or obligation to which
Target is a party or by which Target or any of its properties or assets may be
bound, or (iii) conflict with or violate any permit, concession, franchise,
license, judgment, order, decree, statute, law, ordinance, rule or regulation
applicable to Target or any of its properties or


                                       10
<PAGE>   15

assets, except in the case of (ii) and (iii) for any such conflicts, violations,
defaults, terminations, cancellations or accelerations which would not be
reasonably likely to have a Material Adverse Effect on Target or to interfere
with the consummation by Target of its obligations under this Agreement and the
other Target Transaction Documents.

               (c) The outstanding shares of Target Common Stock and Target
Preferred Stock are the only shares of Target capital stock entitled to vote
with respect to the Merger, and the approval of this Agreement by the holders of
a majority of the issued and outstanding shares of Target Common Stock, voting
as a separate class, and by the holders of a majority of the issued and
outstanding shares of Target Preferred Stock, voting as a separate class, are
the only approvals of Target shareholders required for the consummation of the
Merger, no other vote of any series or class of Target Stock being required. No
consent, approval, order or authorization of, or registration, declaration or
filing with, any Governmental Entity (as defined in Section 10.2) is required by
or with respect to Target in connection with the execution and delivery of this
Agreement or the other Target Transaction Documents or the consummation of the
transactions contemplated hereby or thereby except for (i) the filing of the
Merger Agreement in accordance with the GCL, (ii) the filing of a certificate of
merger in accordance with the DGCL, (iii) items described in Section 3.3 of the
Target Disclosure Schedule, and (iv) such other consents, authorizations,
filings, approvals and registrations which, if not obtained or made, would not
be reasonably likely to have a Material Adverse Effect on Target or materially
and adversely affect the ability of Target to consummate the transactions
contemplated by this Agreement in accordance with its terms.

        Section 3.4 Financial Statements. Target has delivered to Buyer copies
of (i) its audited financial statements as of, and for the years ended, December
31, 1995 and 1996, (ii) its unaudited financial statements as of, and for the
year ended, December 31, 1997 and (iii) its interim financial statements as of,
and for the four-month period ended, April 30, 1998 (collectively, with the
Target 1997 Audited Financials to be delivered pursuant to Section 6.18, the
"Target Financial Statements"). The Target Financial Statements have been, and
will be, prepared in accordance with GAAP applied on a consistent basis
throughout the periods involved, except (in the case of the unaudited financial
statements) for the absence of required footnotes. The Target Financial
Statements present, and will present, fairly in all material respects the
financial position of Target as of the respective dates and the results of
Target's operations and cash flows for the periods indicated, except that the
interim Target Financial Statements are subject to normal and recurring year-end
audit adjustments which will not be material in amount. Target maintains a
standard system of accounting established and administered in accordance with
GAAP.

        Section 3.5 Absence of Liabilities. Target does not have any
liabilities, either accrued or contingent (whether or not required to be
reflected in financial statements in accordance with GAAP), and whether due or
to become due, except for (i) liabilities reflected on Target's balance sheet as
of April 30, 1998 ("the Target Balance Sheet"), (ii) the $350,000 indebtedness
of Target to Buyer pursuant to that certain Promissory Note dated May 29, 1998,
(iii) liabilities incurred in the ordinary course of business that either are
not required to be set forth on the Target Balance


                                       11

Sheet or were incurred thereafter, and (iv) other liabilities listed in Section
3.5 of the Target Disclosure Schedule.

        Section 3.6 Accounts Receivable. The accounts receivable shown on the
Target Balance Sheet arose in the ordinary course of business and have been
collected or will be collectible in the book amounts thereof, less an amount not
in excess of the allowance for doubtful accounts and returns provided for in the
Target Balance Sheet. The accounts receivable of Target arising after the date
of the Target Balance Sheet and prior to the Closing Date arose, or will arise,
in the ordinary course of business and have been collected or will be
collectible in the book amounts thereof, less allowances for doubtful accounts
and returns determined in accordance with the past practices of Target. None of
such accounts receivables is subject to any valid and material claim of offset
or recoupment or counterclaim, and Target has no knowledge of any specific facts
that would be likely to give rise to any such claim; no material amount of such
accounts receivable are contingent upon the performance by Target of any
obligation; and no agreement for deduction or discount has been made with
respect to any such accounts receivable.

        Section 3.7 Inventory. The inventories shown on the Target Balance

quality usable or salable in the ordinary course of Target's business. Since
April 30, 1998, Target has continued to replenish inventories in a normal and
customary manner consistent with past practices. Target has not received notice
that it will experience in the foreseeable future any difficulty in obtaining,
in the desired quantity and quality and at a reasonable price and upon
reasonable terms and conditions, the supplies or component products required for
the manufacture, assembly or production of its products. The value at which
inventories are carried reflect the inventory valuation policy of Target, which
is consistent with its past practice and in accordance with GAAP. Due provision
has been made on the books of Target, consistent with past practices, to provide
for all slow-moving, obsolete, or unusable inventories at their estimated useful
or scrap values, and such inventory reserves are adequate to provide for such
slow-moving, obsolete or unusable inventory and inventory shrinkage.

        Section 3.8 Absence of Certain Changes or Events. Since December 31,
1997, Target has conducted its business in the ordinary course and in a manner
consistent with past practices, and has not:

               (a) to its knowledge, suffered any event or occurrence that has
had or could reasonably be expected to have a Material Adverse Effect on Target,
excluding all events or occurrences that generally affect other companies in the

property, plant or equipment individually in excess of $10,000 or in the
aggregate in excess of $25,000;

               (m) paid, loaned or advanced any amount to, or sold, transferred
or leased any properties or assets to, or entered into any agreement or
arrangement with any of its officers, directors or shareholders or any affiliate
of any of the foregoing, other than employee compensation and benefits and

        Section 4.2 Buyer Capital Structure.

               (a) The authorized capital stock of Buyer consists of 50,000,000
shares of Buyer Common Stock, $0.001 par value, and 2,000,000 shares of
preferred stock, $0.001 par value ("Buyer Preferred Stock"). As of June 9, 1998:
(i) 25,839,855 shares of Buyer Common Stock were issued and outstanding, all of
which are duly authorized, validly issued, fully paid and nonassessable; (ii) no
shares of Buyer Common Stock were held in the treasury of Buyer or by
Subsidiaries of Buyer; (iii) approximately 3,059,987 shares of Buyer Common
Stock were reserved for future issuance pursuant to stock options granted and
outstanding under Buyer's stock option plans (the "Buyer Option Plans") and
rights outstanding under Buyer's employee stock purchase plan (the "Buyer
Purchase Plan") and (iv) 1,645,600 shares of Buyer Common Stock were reserved
for issuance upon conversion of Buyer's outstanding 4 3/4% convertible
subordinated notes due 2002. As of the date of this Agreement, none of the
shares of Buyer Preferred Stock are issued and outstanding. The authorized
capital stock of Sub consists of 1,000 shares of common stock, par value $0.001
per share ("Sub Common Stock"), of which one hundred 100 shares are or will be
issued and outstanding as of the Closing Date. All of the outstanding shares of
capital stock of Sub are duly authorized, validly issued, fully paid and
nonassessable, and all such shares are owned by Buyer free and clear of all
security interests, liens, claims, pledges, agreements, limitations on Buyer's
voting rights, charges or other encumbrances of any nature.

               (b) Except as set forth in Section 4.2(a) or as reserved for
future grants of options under the Buyer Option Plans or the Buyer Purchase
Plan, there are (i) no equity securities of any class of Buyer, or any security
exchangeable into or exercisable for such equity securities, issued, reserved
for issuance or outstanding and (ii) no options, warrants, equity securities,
calls, rights, commitments or agreements of any character to which Buyer is a
party or by which it is bound obligating Buyer to issue, deliver or sell, or
cause to be issued, delivered or sold, additional shares of capital stock of
Buyer or obligating Buyer to grant, extend, accelerate the vesting of or enter
into any such option, warrant, equity security, call, right, commitment or
agreement. To the knowledge of Buyer, there are no voting trusts, proxies or
other agreements or understandings with respect to the shares of capital stock
of Buyer.

               (c) The shares of Buyer Common Stock to be issued pursuant to the
Merger, when issued, will be duly authorized, validly issued, fully paid, and
nonassessable, and free of and not subject to any preemptive rights or rights of
first refusal and (subject to the accuracy of representations and warranties to
be obtained from Target shareholders) will be issued in compliance with all
state and federal securities laws.

        Section 4.3 Authority; No Conflict; Required Filings and Consents.

               (a) Buyer and Sub have all requisite corporate power and
authority to enter into this Agreement and the other documents required to be
executed and delivered by Buyer or Sub hereunder (collectively, the "Buyer
Transaction Documents") and to consummate the transactions contemplated hereby
and thereby. The execution and delivery of this Agreement and the other Buyer
Transaction Documents and the consummation of the transactions


                                       24
<PAGE>   29

contemplated hereby and thereby have been duly authorized by all necessary
corporate action on the part of Buyer and Sub, respectively. This Agreement and
the Buyer Transaction Documents to which they are parties have been duly
executed and delivered by Buyer and Sub and constitute the valid and binding
obligations of Buyer and Sub, respectively, enforceable in accordance with their
terms, except as such enforceability may be limited by (i) bankruptcy laws and
other similar laws affecting creditors' rights generally and (ii) general
principles of equity, regardless of whether asserted in a proceeding in equity
or at law.

               (b) The execution and delivery by Buyer and Sub of this Agreement
and the other Buyer Transaction Documents do not, and the consummation of the
transactions contemplated hereby or thereby will not, (i) conflict with, or
result in any violation or breach of any provision of the Certificate of
Incorporation or Bylaws of Buyer or Sub, (ii) result in any violation or breach
of, or constitute (with or without notice or lapse of time, or both) a default,
or give rise to a right of termination, cancellation or acceleration of any
obligation or loss of any material benefit under, any note, bond, mortgage,
indenture, lease, contract or other agreement, instrument or obligation to which
Buyer or Sub is a party or by which either of them or any of their properties or
assets may be bound, or (iii) conflict with or violate any permit, concession,
franchise, license, judgment, order, decree, statute, law, ordinance, rule or
regulation applicable to Buyer or Sub or any of its or their properties or
assets, except in the case of (ii) and (iii) for any such conflicts, violations,
defaults, terminations, cancellations or accelerations which would not be
reasonably likely to have a Material Adverse Effect on Buyer and its
Subsidiaries, taken as a whole, and that would not interfere with the
consummation by Buyer or Sub of its obligations under this Agreement and the
other Buyer Transaction Documents.

               (c) The outstanding shares of Sub Common Stock are the only
shares of Sub capital stock entitled to vote with respect to the Merger, and the
approval of this Agreement by the holders of a majority of the issued and
outstanding shares of Sub Common Stock is the only approval of Sub shareholders
required for the consummation of the Merger. No consent, approval, order or
authorization of, or registration, declaration or filing with, any Governmental
Entity is required by or with respect to Buyer or any of its subsidiaries in
connection with the execution and delivery of this Agreement or the other Buyer
Transaction Documents or the consummation of the transactions contemplated
hereby or thereby, except for (i) the filing of the Merger Agreement in
accordance with the CGL, (ii) the filing of a certificate of merger in
accordance with the DGCL, (iii) such consents, approvals, orders,
authorizations, registrations, declarations and filings as may be required under
applicable federal and state securities laws and the laws of any foreign
country, and (iv) such other consents, authorizations, filings, approvals and
registrations which, if not obtained or made, would not be reasonably likely to
have a Material Adverse Effect on Buyer and its Subsidiaries, taken as a whole,
or on Sub alone.

        Section 4.4 SEC Filings; Financial Statements.

               (a) Buyer has filed and made available to Target all forms,
reports and documents required to be filed by Buyer with the SEC since December
31, 1995 other than registration statements on Form S-8 (collectively, the

all material respects with the applicable requirements of


                                       25
<PAGE>   30

the Securities Act and the Securities Exchange Act of 1934, as amended (the
"Exchange Act"), as the case may be, and (ii) did not at the time they were
filed (or if amended or superseded by a filing prior to the date of this
Agreement, then on the date of such filing) contain any untrue statement of a
material fact or omit to state a material fact required to be stated in such
Buyer SEC Reports or necessary in order to make the statements in such Buyer SEC
Reports, in the light of the circumstances under which they were made, not
misleading. None of Buyer's Subsidiaries is required to file any forms, reports
or other documents with the SEC.

               (b) Each of the consolidated financial statements (including, in
each case, any related notes) contained in the Buyer SEC Reports, including any
Buyer SEC Reports filed after the date of this Agreement until the Closing,
complied or will comply as to form in all material respects with the applicable
published rules and regulations of the SEC with respect thereto, was or will be
prepared in accordance with GAAP applied on a consistent basis throughout the
periods involved (except as may be indicated in the notes to such financial
statements or, in the case of unaudited statements, as permitted by Form 10-Q
promulgated by the SEC) and fairly presented or will present in all material
respects the consolidated financial position of Buyer and its Subsidiaries as of
the respective dates and the consolidated results of its operations and cash
flows for the periods indicated, except that the unaudited interim financial
statements do not contain notes and were or are subject to normal and recurring
year-end adjustments which were not or are not expected to be material in
amount. The unaudited consolidated balance sheet of Buyer as of March 31, 1998
is referred to herein as the "Buyer Balance Sheet."

               (c) The Buyer SEC Reports, this Agreement, the exhibits and
schedules hereto, and any certificates or documents to be delivered to Target
pursuant to this Agreement, when taken together, do not contain any untrue
statement of a material fact or omit to state any material fact necessary in
order to make the statements contained herein and therein, in light of the
circumstances under which such statements were made, not misleading.

        Section 4.5 Absence of Undisclosed Liabilities. Except as disclosed in
writing to Target or as otherwise disclosed in the Buyer SEC Reports, Buyer and
its Subsidiaries do not have any liabilities, either accrued or contingent
(whether or not required to be reflected in financial statements in accordance
with GAAP), and whether due or to become due, which individually or in the
aggregate would be reasonably likely to have a Material Adverse Effect on Buyer
and its Subsidiaries, taken as a whole, or on Sub alone other than (i)
liabilities reflected in the Buyer Balance Sheet, (ii) liabilities specifically
described in this Agreement, and (iii) normal or recurring liabilities incurred
since March 31, 1998, in the ordinary course of business consistent with past
practices.

        Section 4.6 Absence of Certain Changes or Events. Since March 31, 1998,
Buyer has conducted its business only in the ordinary course and in a manner
consistent with past practice and, since such date, there has not been: (i) any
event or occurrence that has had a Material Adverse Effect on Buyer and its
Subsidiaries, taken as a whole, or on Sub alone; (ii) any damage, destruction or
loss (whether or not covered by insurance) with respect to Buyer having a
Material Adverse Effect on Buyer and its Subsidiaries, taken as a whole, or on
Sub alone; (iii) any material change by Buyer in its accounting methods,
principles or practices to which Target has


                                       26
<PAGE>   31

not previously consented in writing; or (iv) any revaluation by Buyer of any of
its assets having a Material Adverse Effect on Buyer and its Subsidiaries, taken
as a whole, or on Sub alone.

        Section 4.7 Interim Operations of Sub. Sub was formed solely for the
purpose of engaging in the transactions contemplated by this Agreement, has
engaged in no other business activities and has conducted its operations only as
contemplated by this Agreement.

        Section 4.8 Litigation. There is no action, suit, proceeding, claim,
arbitration or investigation pending, or to the knowledge of Buyer, threatened,
against Buyer or Sub which is reasonably likely to have a Material Adverse
Effect on Buyer and its subsidiaries, taken as a whole, or on Sub alone, or
which in any manner challenges or seeks to prevent, enjoin, alter or materially
delay any of the transactions contemplated by this Agreement.

or for access to the properties, books or records of Target by any person or
entity that informs Target that it is considering making, or has made, an
Acquisition Proposal. Such notice shall be made orally and in writing and shall
indicate in reasonable detail the identity of the offeror and the terms and
conditions of such proposal, inquiry or contact.

        Section 6.2 Approval of Shareholders. Target shall promptly after the
date hereof take all action necessary in accordance with the law of the State of
California and its Articles of Incorporation to seek the approval of the Merger
by Target shareholders as soon as possible. As promptly as practicable after the
execution of this Agreement, subject to the review and approval of Buyer, Target
shall prepare and, after receiving the authorization of Buyer, distribute an
information statement (the "Information Statement") to its shareholders for the
purpose of soliciting approval of the Merger by the Target shareholders. The
Information Statement shall include the recommendation of the Board of Directors
of Target in favor of the Merger and this Agreement. Target and Buyer represent
and warrant to the other that the respective information supplied by Target and
Buyer for inclusion in the Information Statement to be sent to the shareholders
of Target shall not, on the date the Information Statement is first mailed to
the shareholders of Target, or at the Effective Time, contain any statement
which, at such time and in light of the circumstances under which it was made,
is false or misleading with respect to any material fact, or omit to state any
material fact necessary in order to make the statements made in the Information
Statement not false or misleading, or omit to state any material fact necessary
to correct any statement in any earlier communication to the Target shareholders
which has become false or misleading. If at any time prior to the Effective Time
any event relating to Target or any of its Affiliates, officers or directors
should be discovered by Target which should be set forth in a supplement to the
Information Statement, Target shall promptly inform Buyer. If at any time prior
to the Effective Time any event relating to Buyer or any of its officers or
directors should be discovered by Buyer which should be set forth in 


                                       30
<PAGE>   35

a supplement to the Information Statement, Buyer shall promptly inform Target.
From the date of this Agreement until the earlier of the termination of this
Agreement or the Effective Time, Buyer shall deliver to Target, promptly after
their filing with the SEC, each Buyer SEC Report, including without limitation
each report on Form 8-K filed by Buyer. Whenever any event occurs which is
required to be set forth in an amendment or supplement to the Information
Statement, Target shall promptly inform Buyer of such occurrence and cooperate
in mailing to shareholders of Target, such amendment or supplement. Target shall
take all other action necessary or advisable to secure the vote or consent of
shareholders required to effect the Merger.

        Section 6.3 Consents. Each of Buyer and Target shall use all reasonable
efforts to obtain all necessary consents, waivers and approvals under its
respective material agreements, contracts, licenses and leases as may be
necessary or advisable to consummate the Merger and the other transactions
contemplated by this Agreement.

        Section 6.4 Access to Information. Upon reasonable notice, Target shall
afford to the officers, employees, accountants, counsel and other
representatives of Buyer, reasonable access, during normal business hours during
the period prior to the earlier of the termination of this Agreement or the
Effective Time, to all its properties, books, contracts, commitments and records
and, during such period, Target shall furnish promptly to Buyer (i) a copy of
each report, schedule, registration statement and other document filed by it
with or received by it from any Governmental Entity and (ii) all other
information concerning its business, properties and personnel as Buyer may
reasonably request. No information or knowledge obtained in any investigation
pursuant to this Section 6.4 shall affect or be deemed to modify any
representation or warranty contained in this Agreement or the conditions to the
obligations of the parties to consummate the Merger. Buyer shall ensure that
each person receiving such access to Target information or properties, or
requesting documents as provided herein, shall be bound by the Joint
Confidentiality Agreement by and between Buyer and Target dated June 18, 1998,
pertaining to the use and disclosure of such Target information.

        Section 6.5 Legal Conditions to Merger. Each of Buyer and Target will
take all reasonable actions necessary to comply promptly with all legal
requirements which may be imposed on itself with respect to the Merger (which
actions shall include, without limitation, furnishing all information in
connection with approvals of or filings with any Governmental Entity) and will
promptly cooperate with and furnish information to each other in connection with
any such requirements imposed upon either of them in connection with the Merger.
Each of Buyer and Target will take all reasonable actions necessary to obtain
(and will cooperate with each other in obtaining) any consent, authorization,
order or approval of, or any exemption by, any Governmental Entity or other
third party, required to be obtained or made by Target, Buyer or Sub in
connection with the Merger or the taking of any action contemplated thereby or
by this Agreement.

<PAGE>   36

        Section 6.6 Public Disclosure. Except with the prior written consent of
Buyer, Target shall issue no press release or other public statement with
respect to the Merger or this Agreement. Prior to the Effective Time, Buyer
shall not make, or cause to be made, any press release or public announcement in
respect of this Agreement or the transaction contemplated hereby without prior
consultation with Target, subject to Buyer's obligations to comply with
applicable securities laws and NASD listing requirements.

        Section 6.7 Nasdaq National Market Listing. Buyer agrees to file with
the Nasdaq National Market (the "NNM") prior to the Effective Time a
Notification Form for Listing of Additional Shares with respect to shares of
Buyer Common Stock issuable, and those required to be reserved for issuance, in
connection with the Merger, upon official notice of issuance.

        Section 6.8 Tax-Free Reorganization. Buyer and Target shall each use its
best efforts to cause the Merger to be treated as a reorganization within the
meaning of Section 368(a) of the Code.

        Section 6.9 Tax Certificates. Buyer and Target each agree to deliver an
executed tax certificate to the other and its counsel in the form attached
hereto as Annex 6.9, which certificate makes certain representations and
warranties regarding the intended tax-free nature of the Merger and Buyer's
intentions regarding the conduct of the business of the Surviving Corporation
following the Merger.



        Section 6.10         Indemnification.

               (a) From and after the Effective Time, Buyer agrees that it will
fulfill and honor and will cause the Surviving Corporation to fulfill and honor
in all respects the obligations of Target pursuant to any indemnification
provisions contained in Target's Articles of Incorporation or Bylaws with
respect to Target's respective directors and officers (the "Target Indemnified
Parties") existing prior to the date hereof. From and after the Effective Time,
such obligations shall be the joint and several obligations of Buyer and the
Surviving Corporation and, by executing this Agreement, Buyer hereby assumes
such obligations. The Articles of Incorporation and Bylaws of the Surviving
Corporation will contain the provisions with respect to indemnification and
elimination of liability for monetary damages set forth in the Articles of
Incorporation and Bylaws of Target, which provisions will not be amended,
repealed or otherwise modified 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, officers, employees or agents of Target,
unless such modification is required by law.

               (b) In the event of any claim, action, suit, proceeding or
investigation to which paragraph (a) applies, (i) any counsel retained by the
Target Indemnified Parties from any period after the Effective Time will be
reasonably satisfactory to the Surviving Corporation and Buyer, (ii) subject to
the provisions, of Target's Articles of Incorporation and Bylaws, and applicable
law, after the Effective Time, the Surviving Corporation or Buyer will pay the
reasonable fees and expenses of such counsel, promptly after statements therefor
are received and (iii) the


                                       32
<PAGE>   37

Surviving Corporation and Buyer will cooperate in the defense of any matter;
provided, however, that neither Buyer nor the Surviving Corporation will be
liable for any settlement effected without the Surviving Corporation's or
Buyer's written consent (which consent will not be unreasonably withheld); and
provided, further, that, in the event that any claim or claims for
indemnification are asserted or made, all rights to indemnification in respect
of any such claim or claims will continue until the disposition of any and all
such claims. The Target Indemnified Parties as a group may retain only one law
firm (in addition to local counsel) to represent them with respect to any single
action unless there is, under applicable standards of professional conduct, a
conflict on any significant issue between the positions of any two or more
Target Indemnified Parties.

               (c) This Section 6.10 will survive any termination of this
Agreement and the consummation of the Merger at the Effective Time, is intended
to benefit Target, the Surviving Corporation and the persons who are or were
directors or officers of Target on or prior to the Effective Time, and will be
binding on all successors and assigns of the Surviving Corporation.

        Section 6.11 Additional Agreements; Reasonable Efforts. Subject to the
terms and conditions of this Agreement, each of the parties agrees to use all
reasonable efforts to take, or cause to be taken, all action and to do, or cause
to be done, all things necessary, proper or advisable under applicable laws and
regulations to consummate and make effective the transactions contemplated by
this Agreement, including cooperating fully with the other party, including by
provision of information. In case at any time after the Effective Time any
further action is necessary or desirable to carry out the purposes of this
Agreement or to vest the Surviving Corporation with full title to all
properties, assets, rights, approvals, immunities and franchises of either of
the Constituent Corporations, the proper officers and directors of each party to
this Agreement shall take all such necessary action.

        Section 6.12         Stock Options.

               (a) At the Effective Time, each outstanding Target Option which
is unexercised, whether vested or unvested, shall be canceled by Target in
accordance with the provisions of Target's 1995 Stock Option Plan.

               (b) Buyer agrees that, at the Effective Time, it shall
irrevocably offer to grant options to purchase an aggregate of at least 211,500
shares of Buyer Common Stock to the persons, and in the share amounts, listed on
Annex 6.12 (the "New Options"). Buyer shall take all corporate action necessary
to reserve for issuance a sufficient number of shares of Buyer Common Stock to
enable the exercise of the New Options in full. Buyer agrees that the Buyer
Common Stock issuable with respect to the New Options shall have been registered
prior to the Effective Time, or as promptly as practicable (and in any event no
later than thirty (30) days after the Effective Time) shall be registered,
pursuant to a registration statement on Form S-8.

        Section 6.13 Target Warrants. At the Effective Time, each outstanding
Target Warrant shall be deemed to constitute a warrant (an "Assumed Warrant") to
acquire, on the same terms and conditions as were applicable under the Target
Warrant, such number of shares of Buyer Common Stock as the holder of such
Target Warrant would have been entitled to receive 


                                       33
<PAGE>   38

pursuant to the Merger (giving effect to the Post-Closing Adjustment) had such
holder exercised such Target Warrant in full immediately prior to the Effective
Time (rounded down to the nearest whole share), at a price per share (rounded up
to the nearest whole cent) equal to (i) the aggregate exercise price per share
of Target Stock purchasable pursuant to such Target Warrant immediately prior to
the Effective Time divided by (ii) the number of full shares of Buyer Common
Stock deemed purchasable pursuant to such Assumed Warrant in accordance with the
foregoing.

        Section 6.14 Stock Grants.

               (a) Buyer agrees that, at the Effective Time, it shall
irrevocably (i) grant an aggregate of 39,865 shares of Buyer Common Stock (the
"Stock Grants") and (ii) pay cash bonuses (the "Cash Bonuses") to the persons,
and in the share and dollar amounts, listed and described on Annex 6.14.

               (b) Buyer shall take all corporate action necessary to reserve
for issuance a sufficient number of shares of Buyer Common Stock to enable the
issuance of the Stock Grants in full. Buyer agrees that the Buyer Common Stock
issuable in the Stock Grants shall have been registered prior to the Effective
Time, or as promptly as practicable (and in any event no later than thirty (30)
days after the Effective Time) shall be registered, pursuant to a registration
statement on Form S-8.

        Section 6.15 Registration of Buyer Common Stock.

               (a) Buyer shall use all reasonable efforts to cause the Buyer
Common Stock issued in exchange for Target Stock and Buyer Common Stock issuable
upon exercise of the Target Warrants (collectively, "Registrable Buyer Common
Stock") to be registered under the Securities Act so as to permit the resale
thereof, and in connection therewith shall prepare and file with the SEC within
forty five (45) days following the Closing, and shall use all reasonable efforts
to cause to become effective no later than ninety (90) days following the
Closing, a registration statement (the "Registration Statement") on Form S-3 or
on such other form as is then available under the Securities Act covering such
Buyer Common Stock; provided, however, that each holder of such Buyer Common
Stock shall provide all such information and materials to Buyer and take all
such action as may be required in order to permit Buyer to comply with all
applicable requirements of the SEC and to obtain any desired acceleration of the
effective date of such Registration Statement. Such provision of information and
materials is a condition precedent to the obligations of Buyer pursuant to this
Section 6.15. Buyer shall not be required to effect more than one (1)
registration under this Section 6.15. The offering made pursuant to such
registration shall not be underwritten.

               (b) Notwithstanding the provisions of Section 6.15(a), Buyer
shall be entitled to a one-time postponement of the declaration of effectiveness
of the Registration Statement prepared and filed pursuant to Section 6.15(a) for
a period of time up to forty-five (45) calendar days after the deadline therefor
set forth in Section 6.15(a), if the Board of Directors of Buyer, acting in good
faith, determines that there exists material nonpublic information about Buyer
which the Board does not wish to disclose in a registration statement, which
information would 


                                       34
<PAGE>   39

otherwise be required by the Securities Act to be disclosed in the Registration
Statement to be filed pursuant to Section 6.15(a) above.

               (c) Subject to the limitations of Section 6.15(b), Buyer shall:
(i) prepare and file with the SEC the Registration Statement in accordance with
Section 6.15(a) with respect to the shares of Registrable Buyer Common Stock and
shall use all reasonable efforts to cause the Registration Statement to become
effective as promptly as practicable after filing and to keep the Registration
Statement effective until the earlier of (A) one (1) year after the Effective
Time or (B) such time as the shares of Registrable Buyer Common Stock can be
sold without compliance with the registration requirements of the Securities
Act; (ii) prepare and file with the SEC such amendments and supplements to the
Registration Statement and the prospectus used in connection therewith as may be
necessary to comply with the provisions of the Securities Act with respect to
the sale or other disposition of all securities proposed to be registered in the
Registration Statement during such period; and (iii) furnish to each holder of
Registrable Buyer Common Stock such number of copies of any prospectus
(including any preliminary prospectus and any amended or supplemented
prospectus) in conformity with the requirements of the Securities Act, and such
other documents, as each such holder may reasonably request in order to effect
the offering and sale of the shares of such Registrable Buyer Common Stock, but
only so long as Buyer shall be required under the provisions hereof to cause the
Registration Statement to remain effective.

               (d) Notwithstanding any other provision of this Section 6.15 but
subject to Section 6.15(e), Buyer shall have the right at any time to require
that all holders suspend open market offers and sales of Registrable Buyer
Common Stock whenever, and for so long as, in the reasonable judgment of Buyer
in good faith after consultation with counsel, there is or may be in existence
material undisclosed information or events with respect to Buyer (the
"Suspension Right"). In the event Buyer exercises the Suspension Right, such
suspension will continue for the period of time reasonably necessary for
disclosure to occur at a time that is not materially detrimental to Buyer and
its stockholders or until such time as the information or event is no longer
material, each as determined in good faith by Buyer after consultation with
counsel. Buyer will use all reasonable efforts to limit the length of any such
suspension to thirty (30) calendar days or less.

               (e) If any holder of Registrable Buyer Common Stock shall propose
to sell any Registrable Buyer Common Stock pursuant to the Registration
Statement, it shall notify the General Counsel of Buyer of its intent to do so
(including the proposed manner and timing of all sales) at least three (3) full
trading days prior to such sale, and the provision of such notice to Buyer shall
conclusively be deemed to reestablish and reconfirm an agreement by such holder
to comply with the registration provisions set forth in this Agreement. Unless
otherwise specified in such notice, such notice shall be deemed to constitute a
representation that any information previously supplied by such holder expressly
for inclusion in the Registration Statement (as such information may have been
superseded by information provided subsequently) is accurate as of the date of
such notice. At any time within such three (3) trading day period, Buyer may
refuse to permit such holder to resell any Registrable Buyer Common Stock
pursuant to the Registration Statement; provided, however, that in order to
exercise this right, Buyer must deliver a certificate 


                                       35
<PAGE>   40

in writing to such holder to the effect that a delay in such sale is necessary
because a sale pursuant to the Registration Statement in its then current form
without the addition of material, non-public information about Buyer could
constitute a violation of the federal securities laws; and provided further,
that Buyer will use all reasonable efforts to limit any such delay to as short a
period as practicable and agrees to notify such holder promptly upon termination
of the suspension. Notwithstanding anything to the contrary in this Agreement,
Buyer will ensure that in any event such holders of Registrable Buyer Common
Stock shall have at least thirty (30) trading days (prorated for partial
quarters) available to sell Buyer Common Stock during each calendar quarter (or
portion thereof) after the effectiveness of the Registration Statement until the
first anniversary of the Effective Time. For any offer or sale of any of
Registrable Buyer Common Stock by a holder of Registrable Buyer Common Stock in
a transaction that is not exempt under the Securities Act, the holder, in
addition to complying with any other federal securities laws, shall deliver a
copy of the final prospectus (or amendment of or supplement to such prospectus)
of Buyer covering the Registrable Buyer Common Stock in the form furnished to
such holder by Buyer to the purchaser of any of the Registrable Buyer Common
Stock on or before the settlement date for the purchase of such Registrable
Buyer Common Stock.

               (f) Buyer will indemnify each holder of Registrable Buyer Common
Stock, each of its officers and directors and partners, and each person
controlling such holder within the meaning of Section 15 of the Securities Act
against all expenses, claims, losses, damages or liabilities (or actions in
respect thereof), including any of the foregoing incurred in settlement of any
litigation, commenced or threatened, arising out of or based on any untrue
statement (or alleged untrue statement) of a material fact contained in any
registration statement, prospectus, preliminary prospectus, offering circular or
other document, or any amendment or supplement thereto, incident to any
registration, qualification or compliance effected pursuant to this Section
6.15, or based on any omission (or alleged omission) to state therein a material
fact required to be stated therein or necessary to make the statements therein,
in light of the circumstances in which they were made, not misleading, or any
violation or any alleged violation by Buyer of any rule or regulation
promulgated under the Securities Act or the Exchange Act in connection with any
such registration, qualification or compliance, and Buyer will reimburse each
such holder, each of its officers and directors, and each person controlling
such holder, each such underwriter and each person who controls any such
underwriter, for any legal and any other expenses reasonably incurred in
connection with investigating, preparing or defending any such claim, loss,
damage, liability or action, as such expenses are incurred; provided, however,
that Buyer will not be liable in any such case to the extent that any such
claim, loss, damage, liability or expense arises out of or is based on any
untrue statement or omission or alleged untrue statement or omission, made in
reliance upon and in conformity with written information furnished to Buyer by
such holder or controlling person for use therein.

               (g) Each holder of Registrable Buyer Common Stock will, if
Registrable Buyer Common Stock held by such holder is included in the securities
as to which such registration is being effected, indemnify Buyer, each of its
directors and officers, each person who controls Buyer within the meaning of
Section 15 of the Securities Act, and each other such holder of Registrable
Buyer Common Stock, each of its officers and directors and each person
controlling such holder within the meaning of Section 15 of the Securities Act,
against all claims, 


                                       36
<PAGE>   41

losses, damages and liabilities (or actions in respect thereof) arising out of
or based on any untrue statement (or alleged untrue statement) of a material
fact contained in any such registration statement, prospectus, offering circular
or other document, or any omission (or alleged omission) to state therein a
material fact required to be stated therein or necessary to make the statements
therein not misleading, and will reimburse Buyer, such other holders of
Registrable Buyer Common Stock, directors, officers, persons or control persons
for any legal or any other expenses reasonably incurred in connection with
investigating or defending any such claim, loss, damage, liability or action, as
such expenses are incurred, in each case to the extent, but only to the extent,
that such untrue statement (or alleged untrue statement) or omission (or alleged
omission) is made in such registration statement, prospectus, offering circular
or other document in reliance upon and in conformity with written information
furnished to Buyer by such holder for use therein.

               (h) Each party entitled to indemnification under Section 6.15(f)
or 6.15(g) (for purposes of this Section 6.15, the "Indemnified Party") shall
give notice to the party required to provide indemnification (for purposes of
this Section 6.15, the "Indemnifying Party") promptly after such Indemnified
Party has actual knowledge of any claim as to which indemnity may be sought, and
shall permit the Indemnifying Party to assume the defense of any such claim or
any litigation resulting therefrom, provided that counsel for the Indemnifying
Party, who shall conduct the defense of such claim or litigation, shall be
approved by the Indemnified Party (whose approval shall not unreasonably be
withheld), and the Indemnified Party may participate in such defense at such
party's expense; provided, however, that an Indemnified Party (together with all
other Indemnified Parties which may be represented without conflict by one
counsel) shall have the right to retain one separate counsel, with the fees and
expenses to be paid by the Indemnifying Party, if representation of such
Indemnified Party by the counsel retained by the Indemnifying Party would be
inappropriate due to differing or potentially differing interests between such
Indemnified Party and any other party represented by such counsel in such
proceeding. The failure of any Indemnified Party to give notice as provided
herein shall not relieve the Indemnifying Party of its obligations under Section
6.15(f) or 6.15(g) unless the failure to give such notice is materially
prejudicial to an Indemnifying Party's ability to defend such action. No
Indemnifying Party, in the defense of any such claim or litigation, shall,
except with the consent of each Indemnified Party, consent to entry of any
judgment or enter into any settlement which does not include as an unconditional
term thereof the giving by the claimant or plaintiff to such Indemnified Party
of a release from all liability in respect to such claim or litigation.

               (i) Buyer shall pay all of the out-of-pocket expenses, other than
underwriting discounts and commissions, if any, incurred in connection with any
registration of Registrable Buyer Common Stock pursuant to this Section 6.15,
including, without limitation, all registration and filing fees, printing
expenses, transfer agents' and registrars' fees, and the reasonable fees and
disbursements of Buyer's outside counsel and independent accountants.

        Section 6.16 Expenses. The parties shall each pay their own legal,
accounting and financial advisory fees and other out-of-pocket expenses related
to the negotiation, preparation and carrying out of this Agreement and the
transactions herein contemplated. In the event the 


                                       37
<PAGE>   42

Merger is consummated, all legal, accounting and financial advisory fees and
other out-of-pocket expenses incurred by Target relating to the negotiation,
preparation and carrying out of this Agreement and the transactions herein
contemplated, (including the termination of the Target 401(k) Plan) and, in all
cases, including such expenses incurred between the date hereof and the Closing
Date (the "Target Transaction Expenses") shall be borne by the Surviving
Corporation, subject to the Post-Closing Adjustment pursuant to Section 2.4.

        Section 6.17 Employee Arrangements.

               (a) Buyer shall offer, or cause the Surviving Corporation to
offer, employment with the Surviving Corporation after the Closing to all of the
employees of Target listed on Annex 6.17 hereto. All such Target employees
accepting employment with the Surviving Corporation shall be eligible for
substantially similar employee benefits, on substantially similar terms, as
other employees of Buyer of comparable rank and length of service. In
determining eligibility for benefits which depend on length of service, Buyer
shall provide each such Target employee with full credit for the period of such
employee's service with Target (other than with respect to options, if any,
granted by Buyer to such Target employees). Except as set forth in this Section
6.17, the terms of employment of such Target employees shall be determined by
agreement of Buyer (or the Surviving Corporation, as the case may be) and each
such employee, provided that such terms of employment include (i) the New
Options and Cash Bonuses set forth as provided in Section 6.12 and (ii) the
Stock Grants as set forth in Section 6.14.

               (b) Buyer shall offer, or cause the Surviving Corporation to
offer, continued group health coverage pursuant to COBRA to those individuals
receiving COBRA coverage through Target Employee Plans immediately prior to the
Closing. With respect to those employees of Target who participate immediately
prior to the Closing in Target Employee Plans (and any dependents of such
employees that participate in Target Employee Plans) that are not offered or do
not accept employment with the Surviving Corporation, Buyer shall offer, or
cause the Surviving Corporation to offer, COBRA coverage to such individuals and
their covered dependents.

        Section 6.18 Target 1997 Audited Financials. Target will cause an audit
to be conducted of Target's financial statements for the year ended December 31,
1997 and, as promptly as practicable following the date of this Agreement shall
deliver to Buyer Target's balance sheet as of December 31, 1997 and its
statements of operations, shareholders' equity and cash flows for the year then
ended, audited and reported upon by its independent certified public accountants
(the "Target 1997 Audited Financials").

        Section 6.19 Voting Agreements. Target shall cause each of Edward Colby,
Philipp Beisel, Greg Seitz, Sequoia Capital VII, Sequoia Technology Partners VI,
Sequoia XXIV, Sequoia 1995, Sequoia 1997, SQP 1997, Hummer Winblad, Venture
Partners II, L.P., Hummer Winblad Technology Fund II, L.P., Hummer Winblad
Technology Fund II (A), L.P., Bay Partners SBIC, Bayview Investors, Ltd., and RS

Agreement, voting agreements and irrevocable proxies in the forms 


                                       38
<PAGE>   43

annexed hereto as Annex 6.19 (the "Voting Agreements"), agreeing, among other
things, to vote in favor of the Merger. Such directors, officers, affiliates and
other shareholders will own, in the aggregate, no less than fifty percent (50%)
of the voting power of each of the outstanding Target Common Stock and Target
Preferred Stock as of the date of this Agreement.

        Section 6.20 Target 401(k) Plan. Target shall take all actions necessary
to ratify the adoption of Target's 401(k) Plan (the "Target 401(k) Plan") and
all amendments thereto prior to the Closing. Target shall take all actions
necessary to terminate the Target 401(k) Plan prior to the Closing. If annual
returns have not been filed for the Target 401(k) Plan for any years for which
such returns are required to be filed, Target shall file such returns under the
U.S. Department of Labor's Delinquent Filer Voluntary Compliance Program.
Penalties required to be paid under such program shall be treated as a liability
of Target and shall be set forth on the Liabilities Certificate for purposes of
determining the Post-Closing Adjustment under Section 2.4.

        Section 6.21 Notification of Certain Matters. Target shall give prompt
notice to Buyer, and Buyer and Sub shall give prompt notice to Target, of the
occurrence, or failure to occur, of any event, which occurrence or failure to
occur, if uncured, would be likely to cause the failure of any of the conditions
set forth in Article VII of this Agreement.

                                   ARTICLE VII

                              CONDITIONS TO MERGER

                           ESCROW AND INDEMNIFICATION

        Section 9.1 Survival of Representations, Warranties, Covenants and
Agreements. The representations, warranties, covenants and agreements of Target
contained in this Agreement or any instrument delivered pursuant to this
Agreement shall survive the Closing Date and shall continue in full force and
effect until the second anniversary of the Closing Date (the "Termination
Date").

        Section 9.2 Indemnification by Target Shareholders.

               (a) Subject to the terms and conditions contained in this Article
IX, the holders of Target Preferred Stock outstanding immediately prior to the
Effective Time (the "Indemnifying Shareholders") shall jointly and severally
indemnify, defend and hold harmless Buyer, its shareholders, officers,
directors, employees and attorneys, all Subsidiaries and affiliates of Buyer,
and the respective officers, directors, employees and attorneys of such entities
(all such persons and entities being collectively referred to as the "Buyer
Group") from, against, for and in respect of any and all claims, losses,
liabilities, damages, costs and expenses (including reasonable legal fees and
expenses and expenses of investigation and defense) which any member of the
Buyer Group may sustain or incur (collectively, "Buyer Losses") which are caused
by or arise out of any inaccuracy in or breach of any of the representations,
warranties, covenants or agreements made by Target in this Agreement, the Target
Disclosure Schedule or any officer certificate delivered pursuant to Section 7.2
or which relate to either the failure to file annual returns for the Target
401(k) Plan for the year 1994 or the failure to properly adopt the Target 401(k)
Plan and any amendments thereto in a form complying with the applicable
requirement of the Code.

               (b) Anything in this Agreement to the contrary notwithstanding,
none of the Indemnifying Shareholders shall be liable for indemnification under
this Section 9.2 until the aggregate of all Buyer Losses for which indemnity is
claimed exceeds $50,000, in which case Buyer shall be entitled to
indemnification for the full amount of the indemnification including the first
$50,000.

               (c) The obligation of the Indemnifying Shareholders to indemnify
members of the Buyer Group for a Buyer Loss under this Article IX is subject to
the condition that the Shareholder Representative (as defined in Section 9.7)
shall have received an Indemnification Claim (as defined in Section 9.3(b)) for
such Buyer Loss on or before the Termination Date.


                                       44
<PAGE>   49

               (d) The amount of Buyer Losses in respect to any Indemnity Claim
shall be reduced by the amount of any insurance payment received by Buyer or the
Surviving Corporation in compensation for such Buyer Losses.

               (e) The provisions of Sections 9.2(b) and (c) and Section 9.6
shall not limit, in any manner, any remedy at law or in equity to which any
member of the Buyer Group shall be entitled against Target or any shareholder or
former shareholder of Target as a result of fraud or intentional
misrepresentation by Target, any Target shareholder or any of their respective
representatives or agents.

        Section 9.3 Procedures for Indemnification.

               (a) As used in this Article IX, the term "Indemnitee" means the
member or members of the Buyer Group seeking indemnification hereunder.

               (b) A claim for indemnification hereunder (an "Indemnification
Claim") shall be made by Indemnitee by delivery of a written notice to the
Shareholder Representative with a copy to the Escrow Agent. The Indemnification
Claim shall specify the basis on which indemnification is sought in reasonable
detail (and shall include relevant documentation related to the Indemnification
Claim), the amount of the asserted Buyer Losses and, in the case of a Third
Party Claim (as defined in Section 9.4), shall contain (by attachment or
otherwise) such other information as Indemnitee shall have concerning such Third
Party Claim.

               (c) If the Indemnification Claim involves a Third Party Claim,
the procedures set forth in Section 9.4 shall be observed by Indemnitee and
Indemnitor.

        Section 9.4 Defense of Third Party Claims. Should any claim be made or
any suit or proceeding instituted by a third party against an Indemnitee which,
if prosecuted successfully, would be a matter for which such Indemnitee would be
entitled to indemnification under this Article IX (a "Third Party Claim"), the
obligations and liabilities of the parties hereunder with respect to such Third
Party Claim shall be subject to the following terms and conditions:

               (a) Indemnitee shall give the Shareholder Representative written
notice of any such claim promptly after receipt by Indemnitee of notice thereof,
and the Shareholder Representative may undertake control of the defense thereof
by counsel of its own choosing reasonably acceptable to Indemnitee. Indemnitee
may participate in the defense through its own counsel at its own expense. The
assumption of the defense of any Third Party Claim by the Shareholder
Representative shall be an acknowledgment by the Indemnifying Shareholders that
such Third Party Claim is subject to indemnification under the provisions of
this Article IX and that such provisions are binding on the Indemnifying
Shareholders. If, however, the Shareholder Representative fails or refuses to
undertake the defense of such Third Party Claim within ten (10) days after
written notice of such claim has been delivered to the Shareholder
Representative by Indemnitee, Indemnitee shall have the right to undertake the
defense, compromise and, subject to Section 9.5, settlement of such Third Party
Claim with counsel of its own choosing. Failure of Indemnitee to furnish written
notice to Indemnitor of a Third Party Claim shall not release the 


                                       45
<PAGE>   50

Indemnifying Shareholders from their obligations hereunder, except to the extent
the Indemnifying Shareholders are prejudiced by such failure.

               (b) Indemnitee and the Indemnifying Shareholders shall cooperate
with each other in all reasonable respects in connection with the defense of any
Third Party Claim, including making available records relating to such claim and
furnishing employees of Indemnitee as may be reasonably necessary for the
preparation of the defense of any such Third Party Claim or for testimony as
witness in any proceeding relating to such claim.

        Section 9.5 Settlement of Third Party Claims. Unless the Shareholder
Representative has failed to fulfill his obligations under Section 9.4, no
settlement by Indemnitee of a Third Party Claim shall be made without the prior
written consent by the Shareholder Representative which consent shall not be
unreasonably withheld or delayed. If the Shareholder Representative has assumed
the defense of a Third Party Claim as contemplated by Section 9.4(a), no
settlement of such Third Party Claim may be made by the Indemnifying
Shareholders without the prior written consent by or on behalf of Indemnitee,
unless such settlement includes a complete release of all claims against
Indemnitee.

        Section 9.6 Resolution of Indemnification Claims.2 Any Indemnification
Claim received by the Shareholder Representative pursuant to Section 9.3 above
will be resolved as follows:

               (a) To provide a fund against which members of the Buyer Group
may assert Indemnification Claims under this Article IX, the Escrow Shares shall
be withheld and deposited into the Escrow in accordance with the provisions of
Section 2.3. The Escrow Shares so deposited shall be held and distributed in
accordance with the Escrow Agreement.

               (b) Subject to the provisions of Section 9.2(e), all
Indemnification Claims shall be made in accordance with this Article IX and the
Escrow Agreement against the Escrow Fund, and no claim for indemnification shall
be asserted against any Indemnifying Shareholder or any other former shareholder
of Target.

               (c) In the event that the Shareholder Representative gives
written notice contesting all, or a portion of, an Indemnification Claim to
Indemnitee (a "Contested Claim") within thirty (30) days after receipt of such
Indemnification Claim, the matter will be settled by binding arbitration
pursuant to Section 9.6(d), unless otherwise agreed by Indemnitor and
Indemnitee. The final decision of the arbitrator shall be furnished to the
Shareholder Representative and Indemnitee in writing and will constitute a
conclusive determination of the issue in question, binding upon the Indemnifying
Shareholders and Indemnitee and shall not be contested or appealed by any of
them.

               (d) Any Contested Claim shall be settled by arbitration at a
mutually agreeable location in Santa Clara, California and, except as herein
specifically stated, in accordance with the commercial arbitration rules of the
American Arbitration Association (the "AAA Rules") then in effect. However, in
all events, these arbitration provisions shall govern over any conflicting rules
which may now or hereafter be contained in the AAA Rules. Any 


                                       46
<PAGE>   51

judgment upon the award rendered by the arbitrator may be entered in any court
having jurisdiction over the subject matter thereof. The arbitrator shall have
the authority to grant any equitable and legal remedies that would be available
in any judicial proceeding instituted to resolve a Contested Claim.

        Section 9.7 Shareholder Representative.

               (a) Authority. For the purposes of this Agreement the holders of
Target Preferred Stock, without any further action on the part of any such
shareholder, shall be deemed to have consented to the appointment of Philipp
Beisel as the representative of such shareholders (the "Shareholder
Representative"), as the attorney-in-fact for and on behalf of each such
shareholder, and the taking by the Shareholder Representative of any and all
actions and the making of any decisions required or permitted to be taken by
them under this Agreement or the Escrow Agreement, including, without
limitation, the exercise of the power to (i) execute the Escrow Agreement, (ii)
prepare, or cause to be prepared, and deliver to Buyer the Signing Date Balance
Sheet, the Closing Date Balance Sheet and the Liabilities Certificate, (iii)
negotiate and agree with Buyer on the amount of the Post-Closing Adjustment,
(iv) receive or give any notice on behalf of the Indemnifying Shareholders
pursuant to this Agreement or the Escrow Agreement, (v) authorize delivery to
Buyer of the Escrow Shares, or any portion thereof, in satisfaction of
Indemnification Claims, (vi) agree to, negotiate, enter into settlements and
compromises of, and demand arbitration and comply with orders of courts and
awards of arbitrators with respect to, such Indemnification Claims, and (vii)
take all other actions necessary in the judgment of the Shareholder
Representative for the accomplishment of the foregoing and all of the other
terms, conditions and limitations of this Agreement and the Escrow Agreement.
Accordingly, the Shareholder Representative has the authority and power
conferred by this Agreement to act on behalf of each holder of Target Preferred
Stock and each Indemnifying Shareholder with respect to this Agreement and the
Escrow Agreement and the disposition, settlement or other handling of all
claims, rights or obligations arising from and taken pursuant to this Agreement
or the Escrow Agreement. Such shareholders will be bound by all actions taken by
the Shareholder Representatives in connection with this Agreement and the Escrow
Agreement, and Buyer shall be entitled to rely on any action or decision of the
Shareholder Representative as the action or decision of each holder of Target
Preferred Stock and each Indemnifying Shareholder.

               (b) Standard of Conduct. Neither the Shareholder Representative
nor any of his agents shall be liable to any holder of Target Preferred Stock or
any Indemnifying Shareholder for any error of judgment, act done or omitted by
him, or mistake of fact or law in connection with his services pursuant to
Section 9.7, unless caused by his own gross negligence or willful misconduct. In
taking any action or refraining from taking any action whatsoever the
Shareholder Representative shall be protected in relying upon any notice, paper
or other document reasonably believed by him to be genuine, or upon any evidence
reasonably deemed by him to be sufficient. The Shareholder Representative shall
not be required to take any action which is contrary to this Agreement, the
Escrow Agreement or applicable law. The Shareholder Representative may consult
with counsel in connection with his duties and shall be fully protected in any
act taken, suffered or permitted by him in good faith in accordance with the


                                       47
<PAGE>   52

advice of counsel. In connection with his services under Section 9.7, the
Shareholder Representative shall not be responsible for determining or verifying
the authority of any person acting or purporting to act on behalf of any party
to this Agreement.

               (c) Indemnification of the Shareholder Representative. Each
Indemnifying Shareholder shall indemnify the Shareholder Representative, ratably
in accordance with the value of the shares of Buyer Common Stock received by
such shareholder in the Merger, for any and all liabilities, obligations,
losses, damages, penalties, actions, judgments, suits, costs, expenses or
disbursements of any kind or nature whatsoever which may at any time be imposed
on, incurred by or asserted against the Shareholder Representative in any way
relating to or arising out of this Agreement or any documents contemplated by or
referred to herein or therein or the transactions contemplated hereby or thereby
or the enforcement of any of the terms hereof or thereof or of any such other
documents; provided, however, that no such shareholder shall be liable for any
of the foregoing to the extent they arise from the Shareholder Representative's
gross negligence or willful misconduct. The Shareholder Representative shall be
fully justified in refusing to take or to continue to take any action hereunder
unless it shall first be indemnified to its reasonable satisfaction by such
shareholder against any and all liability and expense which may be incurred by
it by reason of taking or continuing to take any such action.

               (d) Resignation or Removal of the Shareholder Representative.
Subject to the appointment and acceptance of a successor Shareholder
Representative as provided below, the Shareholder Representative may resign at
any time thirty (30) days subsequent to giving notice thereof to all
Indemnifying Shareholders, Buyer and the Escrow Agent, and the Shareholder
Representative may be removed at any time with or without cause by action of the
Indemnifying Shareholders who represent a majority of the shares of all
Indemnifying Shareholders. Upon any such resignation or removal, Indemnifying
Shareholders representing a majority of the shares of the Indemnifying
Shareholders shall have the right to appoint a successor Shareholder
Representative, which Shareholder Representative shall be reasonably acceptable
to Buyer. If no successor Shareholder Representative shall have been appointed
by Indemnifying Shareholders and accepted such appointment within twenty (20)
days after the retiring Shareholder Representative gives notice of resignation
or the Shareholder Representative's removal, then the retiring or removed
Shareholder Representative may appoint a successor which shall be reasonably
acceptable to Buyer. Upon the acceptance of any appointment as Shareholder
Representative hereunder, such successor Shareholder Representative shall
thereupon succeed to and become vested with all the rights, powers, privileges
and duties of the retiring or removed Shareholder Representative, and the
retiring or removed Shareholder Representative shall be discharged from its
duties and obligations hereunder. After any retiring Shareholders
Representative's resignation or removal hereunder as the Shareholder
Representative, the provisions of this Section 9.7 shall continue in effect for
its benefit in respect of any actions taken or omitted to be taken by it while
he was acting as the Shareholder Representative.

               (e) Individual Capacity. The Shareholder Representative, to the
extent he is an Indemnifying Shareholder, shall have the same rights and powers

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.

        Section 10.5 Entire Agreement. This Agreement (including the documents

                            FORM OF ESCROW AGREEMENT


<PAGE>   59
                                ESCROW AGREEMENT


        THIS ESCROW AGREEMENT is made and entered into as of June 30, 1998 by
and among The Vantive Corporation, a Delaware corporation ("Buyer"), Harris
Trust and Savings Bank (the "Escrow Agent") and Philipp Beisel (the "Shareholder
Representative") for and on behalf of holders of Preferred Stock (the
"Indemnifying Shareholders") of Wayfarer Communications, Inc., a California
corporation ("Revo").

                                 R E C I T A L S

        A. Pursuant to that certain Agreement and Plan of Reorganization dated
as of June 18, 1998 (the "Plan of Reorganization"), Buyer will issue to the
Indemnifying Shareholders shares of Buyer Common Stock, $0.001 par value ("Buyer
Common Stock"), pursuant to the merger (the "Merger") of Revo Acquisition
Corporation, a Delaware corporation and wholly-owned subsidiary of Buyer
("Sub"), with and into Revo;

        B. Pursuant to Section 2.4 of the Plan of Reorganization, a Post-Closing
Adjustment (as defined therein) will be made with respect to the number of
shares of Buyer Common Stock issuable to the Indemnifying Shareholders in the
Merger;

        C. Pursuant to Article IX of the Plan of Reorganization, the
Indemnifying Shareholders have agreed to indemnify Buyer and other members of
the Buyer Group (as defined therein) with respect to inaccuracies in or breaches
of representations, warranties or covenants made by Revo in the Plan of
Reorganization and certain other matters; and

        D. In accordance with the Plan of Reorganization, the parties desire to
establish an escrow for the purpose of providing a fund (i) from which the
Post-Closing Adjustment may be deducted and (ii) against which Buyer (on behalf
of itself and other members of the Buyer Group) may seek indemnification from
the Indemnifying Shareholders under the Plan of Reorganization.

        NOW, THEREFORE, in consideration of the foregoing premises and the
mutual obligations herein, the parties agree as follows:

        1.     Establishment of Escrow. On the date hereof or as soon thereafter
as practicable, Buyer shall deliver to the Escrow Agent for deposit into escrow
(the "Escrow") certificates representing an aggregate of 44,076 shares of Buyer
Common Stock otherwise distributable to the Indemnifying Shareholders in the
Merger (the "Escrow Shares"). The Escrow Shares so delivered to the Escrow Agent
and any other securities, cash or other property from time to time held by the
Escrow Agent pursuant to the terms hereof is herein referred to as the "Escrow
Fund." The Escrow Agent agrees to accept the Escrow Shares and to hold the
Escrow Fund in escrow subject to the terms and conditions of this Escrow
Agreement.


                                       1
<PAGE>   60

        2.     Maintenance of the Escrow. The Escrow Agent shall establish a
separate account for each Indemnifying Shareholder showing the number of Escrow
Shares and the amount and type of other property, if any, held in the Escrow for
such Indemnifying Shareholder on the basis of a list of the Indemnifying
Shareholders' respective ownership percentage provided to the Escrow Agent by
the Shareholder Representative. The Escrow Agent shall maintain records showing
each Indemnifying Shareholder's Proportionate Interest (as defined below) in the
Escrow Fund and shall adjust each Indemnifying Shareholder's account to reflect
distributions from, and additions or substitutions to, the property held for the
account of such Indemnifying Shareholder in the Escrow so that, at all times,
each Indemnifying Shareholder's Proportionate Interest in the Escrow Fund shall
be maintained. For purposes of this Escrow Agreement, each Indemnifying
Shareholder's "Proportionate Interest" in the Escrow Fund as of a specific date
shall be equal to the percentage that the value of the Escrow Shares and other
property held for the account of such Indemnifying Shareholder in the Escrow
bears to the value of all property held for the account of all Indemnifying
Shareholders in the Escrow as of such date. For purposes of the provisions of
this Escrow Agreement relating to indemnification and claims, the Escrow Shares
shall be deemed to have a value equal to the average closing sale price of Buyer
Common Stock (as quoted on the Nasdaq National Market and reported in The Wall
Street Journal) for the ten (10) trading days next preceding the date of a
valuation. The Escrow Agent is hereby granted the power to effect any transfer
of Escrow Shares required by this Agreement. Buyer shall cooperate with the
Escrow Agent in promptly issuing, or causing its transfer agent to promptly
issue, such stock certificates as shall be required to effect such transfers.
All Escrow Shares and any other securities from time to time held in the Escrow
Fund shall be registered in the name of the Escrow Agent or its nominee.

        3.     Shareholder Representative. From and after the establishment of 
the Escrow as provided in Section 1 hereof, the Indemnifying Shareholders shall
be represented by the Shareholder Representative, or, upon written notice to the
Escrow Agent, by his successor appointed in accordance with Section 9.7 of the
Plan of Reorganization, who shall have the duties and authority set forth in
said section.

        4.     Dividends, Voting and Rights of Ownership. Except for tax-free
dividends paid in stock declared with respect to the Escrow Shares pursuant to
Section 305(a) of the Internal Revenue Code of 1986, as amended (the "Code'),
which shall be treated in the manner set forth in Section 1 hereof, any cash
dividends, dividends payable in securities or other distributions of any kind
made in respect of the Escrow Shares will be distributed currently to the
Indemnifying Shareholders and, if distributed to the Escrow Agent, shall
promptly be paid over to the Indemnifying Shareholders. Each Indemnifying
Shareholder will have voting rights with respect to the Escrow Shares deposited
in the Escrow with respect to such Indemnifying Shareholder so long as such
Escrow Shares are held in the Escrow, and Buyer shall take all reasonable steps
necessary to allow the exercise of such rights. The Escrow Agent shall forward
to the Shareholder Representative all voting materials and proxies received by
the Escrow Agent. In the event an Indemnifying Shareholder elects to vote, it
shall direct the Escrow Agent in writing to do so. In the absence of such
direction, the Escrow Agent shall have no duty or obligation to vote with
respect to any of the Escrow Shares. While the Escrow Shares remain in the
Escrow Agent's possession pursuant to this Escrow Agreement, the Indemnifying
Shareholders will 


                                       2
<PAGE>   61

retain and will be entitled to exercise all other incidents of ownership of the
Escrow Shares which are not inconsistent with the terms and conditions of this
Escrow Agreement. Subject to the rights of Buyer and the other members of the
Buyer Group under the Plan of Reorganization and this Escrow Agreement, all
beneficial interest in the Escrow Fund shall be the property of the Indemnifying
Shareholders from and after the Closing, and Buyer shall have no interest
therein. None of the rights of the Indemnifying Shareholders hereunder shall be
transferable except as otherwise provided by law. Each of the Indemnifying
Shareholders shall be obligated for all federal, state or local taxes applicable
to such Indemnifying Shareholder's interest in the Escrow Fund.

        5.     Post-Closing Adjustment.

               (a) Within five (5) business days following the determination of
the Post-Closing Adjustment pursuant to Section 2.4(b) or 2.4(c) of the Plan of
Reorganization, Buyer and the Shareholder Representative shall give written
notice to the Escrow Agent directing the Escrow Agent to deliver out of the
Escrow to Buyer the number of Escrow Shares determined by dividing the amount of
the Post-Closing Adjustment by $31.9375, rounded to the nearest whole share.

               (b) Within ten (10) business days following delivery of such
notice, the Escrow Agent will (i) deliver out of the Escrow to Buyer the number
of Escrow Shares specified in Section 5(a) hereof and (ii) deliver out of the
Escrow to the Indemnifying Shareholders (in accordance with their Proportionate
Interests) the number of Escrow Shares remaining in the Escrow after the
distribution specified in clause (i) above, to the extent such remaining Escrow
Shares exceed (A) 35,261, plus (B), the number of whole Escrow Shares having an
aggregate value at the time of such delivery most nearly equal to the amount of
any then pending Indemnification Claims (as defined in and asserted pursuant to
Section 6 hereof), and expenses reasonably estimated by Buyer to be necessary
for the disposition of all such Indemnification Claims.

        6.     Claims for Indemnification; Disposition Thereof.

               (a) If an Indemnitee (as defined in the Plan of Reorganization)
shall, during the term of this Escrow Agreement, have any claim for
indemnification pursuant to Article IX of the Plan of Reorganization
("Indemnification Claim"), such Indemnitee or Buyer shall promptly deliver to
the Shareholder Representative and the Escrow Agent written notice of such an
Indemnification Claim in accordance with Section 9.3(b) of the Plan of
Reorganization.

               (b) If the Shareholder Representative shall not have notified
Buyer and the Escrow Agent in writing objecting to the delivery of any of the
Escrow Fund out of the Escrow to Buyer for application to such notice of Claim
within thirty (30) calendar days after delivery of notice of such
Indemnification Claim, the Escrow Agent shall, as promptly as practicable
following the expiration of such period, deliver out of the Escrow to Buyer the
number of whole Escrow Shares and/or other property then held in the Escrow
having an aggregate value at the time of such delivery most nearly equal to the
amount of such Indemnification Claim.


                                       3
<PAGE>   62

               (c) If the Shareholder Representative gives written notice to the
Escrow Agent and Buyer objecting to the delivery of any of the Escrow Fund out
of the Escrow to Buyer for application to an Indemnification Claim (a "Contested
Claim") within the 30-day period specified in Section 6(b) hereof, the Escrow
Agent shall make no delivery to Buyer out of the Escrow Fund with respect to
such Contested Claim until the rights of the Indemnifying Shareholders and the
Indemnitee with respect thereto have been agreed upon between the Shareholder
Representative and Buyer or until such rights are finally determined by
arbitration pursuant to Section 14 hereof. If the arbitrator in such proceeding
shall determine that the Escrow Fund, or any part thereof, is to be delivered
out of the Escrow to Buyer to satisfy such Contested Claim, the Escrow Agent
shall, as promptly as practicable following receipt of such determination,
deliver out of the Escrow to Buyer the number of whole Escrow Shares and/or
other property then held in the Escrow having an aggregate value most nearly
equal to the amount determined by such arbitrator .

               (d) All Indemnitees wishing to assert substantially similar
claims against the Escrow must assert such claims in the same Indemnification
Claim and in the same arbitration proceeding. A decision or result with respect
to any Indemnification Claim asserted by an Indemnitee will be final, binding
and conclusive upon all Indemnitees with respect to any substantially similar
Indemnification Claims of such Indemnitees asserted or to be asserted against
the Escrow.

        7.     Distribution of Escrow Fund; Termination of Escrow. The portion 
of the Escrow Fund not previously distributed in accordance with the terms of
Section 5 and Section 6 hereof shall be held by the Escrow Agent until ten (10)
business days following the second anniversary of this Escrow Agreement (the
"Release Date"), at which time it shall be delivered to the Indemnifying
Shareholders in accordance with their Proportionate Interests. Notwithstanding
the foregoing, there shall be retained in the Escrow the lesser of (i) the
number of Escrow Shares and other property then held in the Escrow having an
aggregate value equal to 100% of the amount of all pending Indemnification
Claims asserted pursuant to Section 6 hereof and expenses reasonably estimated
by Buyer to be necessary for the disposition of all such Indemnification Claims,
and (ii) the entire remaining Escrow Fund. The Escrow Fund not so distributed
shall be retained by the Escrow Agent until all such pending Indemnification
Claims are resolved and the remaining Escrow Fund deliverable to any Buyer as a
result thereof, if any, shall have been delivered to Buyer. Thereafter, the
Escrow Agent shall, as promptly as practicable, deliver the remaining Escrow
Fund to the Indemnifying Shareholders in accordance with their Proportionate
Interests.

        8.     Term of Escrow Agreement. This Escrow Agreement shall terminate 
upon the distribution by the Escrow Agent of all property held in the Escrow
Fund.

        9.     Fees of the Escrow Agent. Buyer and the Shareholder 
Representative (on behalf of the Indemnifying Shareholders) agree, jointly and
severally to pay to the Escrow Agent a fee according to the fee schedule
attached as Schedule I hereto and all of the expenses of the Escrow Agent,
including expenses related to the indemnity provided in Section 12 hereof. To
the extent 


                                       4
<PAGE>   63

such fees and expenses are not paid by Buyer, they may paid from the Escrow Fund
after ten (10) days written notice from the Escrow Agent to Buyer and the
Shareholder Representative. As between themselves, Buyer and the Shareholder
Representative (on behalf of the Indemnifying Shareholders) agree that: (i) all
fees and expenses payable to the Escrow Agent will be paid in the first instance
by Buyer as and when they became payable; (ii) the normal and usual fees and
expenses of administering the Escrow and the distribution made pursuant to
Section 5 hereof shall be borne by Buyer; and (iii) all fees and expenses
associated with the administration of any Indemnification Claim shall be borne
by the Indemnifying Shareholders and shall be recoverable by Buyer out of the
Escrow as a part of such Indemnification Claim.

        10.    Liability of the Escrow Agent. In performing any of its duties 
under this Escrow Agreement, the Escrow Agent shall not be liable to any party
for damages, losses or expenses, except in the event of gross negligence or
willful misconduct on its part. The Escrow Agent shall not incur any such
liability for (i) any act or failure to act made or omitted in good faith, or
(ii) any action taken or omitted in reliance upon any instrument, including any
written statement or affidavit provided for in this Escrow Agreement that the
Escrow Agent shall in good faith believe to be genuine; nor will the Escrow
Agent be liable or responsible for forgeries, fraud, impersonations, or
determining the scope of any agent's authority. In addition, the Escrow Agent
may consult with legal counsel of its choice in connection with its duties under
this Agreement and shall be fully protected in any act taken, suffered, or
permitted by it in good faith in accordance with the advice of counsel. The
Escrow Agent is not responsible for determining and verifying the authority of
any person acting or purporting to act on behalf of any party to this Escrow
Agreement. The Escrow Agent undertakes to perform such duties as are
specifically set forth in this Escrow Agreement, and the Escrow Agent shall not
be liable except for the performance of such duties as are specifically set
forth in this Escrow Agreement. No implied covenants or obligations shall be
read into this Escrow Agreement against the Escrow Agent.

        11.    Controversies. If any controversy arises between the parties to 
this Escrow Agreement, or with any other party, concerning the subject matter of
the Escrow, its terms or conditions, the Escrow Agent will not be required to
determine the controversy or to take any action regarding it. The Escrow Agent
may hold all documents and funds and may wait for settlement of any such
controversy by final appropriate legal proceedings or other means as, in the
Escrow Agent's discretion, it may require, despite what may be set forth
elsewhere in this Escrow Agreement. In such event, the Escrow Agent will not be
liable for interest or damage. Furthermore, the Escrow Agent may at its option,
file an action of interpleader requiring the parties to answer and litigate any
claims and rights among themselves. The Escrow Agent is authorized to deposit
with the clerk of the court all documents and funds held in the Escrow, except
all costs, expenses, charges and reasonable attorneys' fees incurred by it due
to the interpleader action and which the parties jointly and severally agree to
pay. Upon initiating such action, the Escrow Agent shall be fully released and
discharged of and from all obligations and liability imposed by the terms of the
Escrow.

        12.    Indemnification of Escrow Agent. Buyer and the Indemnifying
Shareholders and their respective successors and assigns agree jointly and
severally to indemnify and hold the Escrow Agent harmless against any and all
losses, claims, damages, liabilities and expenses,


                                       5
<PAGE>   64

including reasonable costs of investigation, counsel fees, including allocated
costs of in-house counsel, and disbursements that may be imposed on the Escrow
Agent, or incurred by it in connection with the performance of its duties under
this Escrow Agreement, including but not limited to any arbitration or
litigation arising from this Escrow Agreement or involving its subject matter.
The costs and expenses of enforcing this right of indemnification shall be paid
by Buyer and the Indemnifying Shareholders, provided, however, that the Buyer
and the Indemnifying Shareholders shall not pay such costs and expenses to the
extent that the Escrow Agent is judicially determined to have been negligent or
acted with willful misconduct. This right of indemnification shall survive the
termination of this Escrow Agreement, and the removal or resignation of the
Escrow Agent. Nothing contained in this Section 12 shall impair the rights of
the Indemnifying Shareholders and Buyer, as between themselves, including
without limitation, their rights to enforce the provisions of Section 9 hereof
with respect to the allocation of the Escrow Agent's fees.

        13.    Resignation of Escrow Agent. The Escrow Agent may resign at any 
time upon giving at least thirty (30) days written notice to the other parties;
provided, however, that no such resignation shall become effective until the
appointment of a successor Escrow Agent which shall be accomplished as follows:
Buyer and the Shareholder Representative shall use their best efforts to agree
on a successor Escrow Agent within thirty (30) days after receiving such notice.
If the parties fail to agree on a successor Escrow Agent within such time, the
Escrow Agent may, at the expense of Buyer and the Shareholder Representative,
petition any court of competent jurisdiction for the appointment of a successor
Escrow Agent authorized to do business in the State of California and, in such
event, shall give written notice to the other parties of such appointment. The
successor Escrow Agent shall execute and deliver to the Escrow Agent an
instrument accepting such appointment, and the successor Escrow Agent shall,
without further acts, be vested with all the estates, property rights, powers,
and duties of the predecessor Escrow Agent as if originally named as Escrow
Agent herein. The predecessor Escrow Agent then shall be discharged from any
further duties and liability under this Escrow Agreement.

        14.    Arbitration.

               (a) Each Contested Claim will be settled by binding arbitration
pursuant to Section 9.6(d) of the Plan of Reorganization unless otherwise agreed
by the Shareholder Representative and Buyer. Any portion of a Contested Claim
which is not contested shall be resolved as set forth in Section 6(b) hereof.
The final decision of the arbitrator shall be furnished to the Escrow Agent, the
Shareholder Representative and Buyer in writing and will constitute a conclusive
determination of the issue in question, binding upon Revo, the Indemnifying
Shareholders and Buyer and shall not be contested or appealed by any of them.
After notice that the Indemnification Claim is contested by the Shareholder
Representative, the Escrow Agent will continue to hold in the Escrow Fund Escrow
Shares and/or other property having a value sufficient to cover such Contested
Claim, as determined pursuant to Section 2 hereof (notwithstanding the
occurrence of the Release Date), until the earlier of the receipt by the Escrow
Agent of (i) a settlement agreement executed by Buyer and the Shareholder
Representative setting forth a resolution of such Contested Claim, or (ii)
receipt of a copy of the final award of the arbitrator with respect to such
Contested Claim.

               (b) The number of Escrow Shares to be delivered upon resolution
of a Contested Claim shall be equal to (i) the aggregate dollar amount of the
Contested Claim as determined pursuant to this Section 14 divided by (ii) the
value of the Escrow Shares, as determined pursuant to Section 2 hereof, as of
the date of such determination.

        15.    Miscellaneous.

               (a) Assignment; Binding upon Successors and Assigns. None of the

successors and permitted assigns.

               (b) Severability. If any provision of this Escrow Agreement, or
the application thereof, shall for any reason and to any extent be held to be
invalid or unenforceable, the remainder of this Escrow Agreement and the
application of such provision to other persons or circumstances shall be
interpreted so as best to reasonably effect the intent of the parties hereto.
The parties further agree to replace such invalid or unenforceable provision of
this Escrow Agreement with a valid and enforceable provision which will achieve,
to the extent possible, the economic, business and other purposes of the invalid
or unenforceable provision.

                                VOTING AGREEMENT


        THIS VOTING AGREEMENT is made and entered into as of June ___, 1998 by
and between The Vantive Corporation, a Delaware corporation (the "Company"), and
the undersigned shareholder (the "Shareholder") of Wayfarer Communications,
Inc., a California corporation ("Wayfarer").


                                    RECITALS

        A. Concurrently with the execution of this Agreement, the Company,
Wayfarer and Revo Acquisition Corporation, a Delaware corporation and a
wholly-owned subsidiary of the Company ("Sub"), have entered into an Agreement
and Plan of Reorganization dated as of June ___, 1998 (the "Reorganization
Agreement"), providing for the merger of Sub with and into Wayfarer (the
"Merger") pursuant to which Wayfarer will become a wholly-owned subsidiary of
the Company;

        B. The Shareholder is the beneficial holder of record of the number of
shares of the outstanding Common Stock and/or Preferred Stock of Wayfarer as is
indicated on the final page of this Agreement (the "Shares");

        C. In connection with the Merger, the Company will acquire the
Shareholder's entire equity interest in Wayfarer and the Shareholder will
receive in exchange an equity interest in the Company; and

        D. In consideration of and to induce the execution of the Reorganization
Agreement by the Company, the Shareholder is willing to agree not to sell or
otherwise dispose of any shares of Wayfarer stock held by the Shareholder and to
vote the Shares so as to facilitate consummation of the Merger, as more fully
set forth in this Agreement.

        NOW, THEREFORE, in consideration of the premises and the mutual
covenants and agreements contained herein, the parties agree as follows:

        1. Agreement to Retain Shares. The Shareholder agrees not to transfer,
pledge, sell, exchange or offer to transfer or sell or otherwise dispose of or
encumber any of the Shares at any time prior to the Expiration Date, as defined
herein. The "Expiration Date" shall mean the earlier of (i) the date and time on
which the Merger shall become effective in accordance with the terms and
provisions of the Reorganization Agreement or (ii) the date on which the
Reorganization Agreement shall be terminated pursuant to Article VIII of the
Reorganization Agreement.

        2. Agreement to Vote Shares. At any meeting of the Wayfarer shareholders
called with respect to any of the following, and at any adjournment thereof, and
with respect to any written consent solicited with respect to any of the
following, the Shareholder agrees to vote the Shares: (i) in favor of approval
of the Reorganization Agreement and the Merger and any matter which would, or
could reasonably be expected to, facilitate the Merger and (ii) against approval


                                       1
<PAGE>   79

of any proposal made in opposition to or competition with consummation of the
Merger and the Reorganization Agreement, against any other merger,
consolidation, sale of assets or reorganization with any other party, against
any recapitalization, liquidation, or winding up of Wayfarer and against any
other matter which would, or could reasonably be expected to, prohibit or
discourage the Merger (each of the foregoing is referred to as an "Opposing
Proposal"). The Shareholder, as the holder of voting stock of Wayfarer agrees to
be present, in person or by proxy, at all meetings of shareholders of Wayfarer
held prior to the Expiration Date so that all Shares are counted for the
purposes of determining the presence of a quorum at such meetings. This
Agreement is intended to bind the Shareholder only with respect to the specific
matters set forth herein, and shall not prohibit the Shareholder from acting in
accordance with his fiduciary duties as an officer or director of Wayfarer.

        3. Irrevocable Proxy. Concurrently with the execution of this Agreement,
the Shareholder agrees to deliver to the Company a proxy in the form attached
hereto as Annex A (the "Proxy"), which shall be irrevocable to the extent
provided therein; provided that the Proxy shall be revoked upon termination of
this Agreement in accordance with its terms.

        4. Additional Purchases. For purposes of this Agreement, the term
"Shares" shall include any shares of Wayfarer capital stock which the
Shareholder purchases or otherwise acquires after the execution of this
Agreement and prior to the Expiration Date.

        5. Representations, Warranties and Covenants of the Shareholder. The
Shareholder hereby represents, warrants and covenants to the Company the
following:

           5.1 Ownership of Shares. Except as specifically described on Annex B
to this Agreement, the Shareholder (i) is the holder and beneficial owner of the
Shares, which at the date hereof are, and at all times until the Expiration Date
will be, free and clear of any liens, claims, options, charges or other
encumbrances, (ii) does not beneficially own any shares of stock of Wayfarer
other than the Shares and (iii) has full power and authority to make, enter
into, deliver and carry out the terms of this Agreement and the Proxy.

           5.2 Validity; No Conflict. This Agreement constitutes the legal,
valid and binding obligation of the Shareholder. Neither the execution of this
Agreement by the Shareholder nor the consummation of the transactions
contemplated hereby will result in a breach or violation of the terms of any
agreement by which the Shareholder is bound or of any decree, judgment, order,
law or regulation now in effect of any court or other governmental body
applicable to the Shareholder.

           5.3 No Voting Trusts and Agreements. Between the date of this
Agreement and the Expiration Date, the Shareholder will not, and will not permit
any entity under the Shareholder's control to, deposit any shares of Wayfarer
capital stock held by the Shareholder or such entity in a voting trust or
subject any shares of Wayfarer capital stock held by the Shareholder or such
entity to any arrangement or agreement with respect to the voting of such shares
of capital stock, other than agreements entered into with the Company.


                                       2
<PAGE>   80

           5.4 No Proxy Solicitations. Between the date hereof and the
Expiration Date, the Shareholder will not, and will not permit any entity under
the Shareholder's control to, (i) solicit proxies or become a participant in a
"solicitation" (as such term is defined in Rule 14a-11 under the Securities
Exchange Act of 1934, as amended (the "Exchange Act")), with respect to an
Opposing Proposal or otherwise encourage or assist any party in taking or
planning any action which would compete with, restrain or otherwise serve to
interfere with or inhibit the timely consummation of the Merger in accordance
with the terms of the Reorganization Agreement, (ii) initiate a shareholders'
vote or action by written consent of Wayfarer shareholders or (iii) become a
member of a "group" (as such term is used in Section 13(d) of the Exchange Act)
with respect to any voting securities of Wayfarer with respect to an Opposing
Proposal.

        6. Representations, Warranties and Covenants of the Company. The Company
represents, warrants and covenants to the Shareholder as follows:

           6.1 Due Authorization. This Agreement has been authorized by all
necessary corporate action on the part of the Company and has been duly executed
by a duly authorized officer of the Company.

           6.2 Validity; No Conflict. This Agreement constitutes the legal,
valid and binding obligation of the Company. Neither the execution of this
Agreement by the Company nor the consummation of the transactions contemplated
hereby will result in a breach or violation of the terms of any agreement by
which the Company is bound or of any decree, judgment, order, law or regulation
now in effect of any court or other governmental body applicable to the Company.

        7. Additional Documents. The Shareholder and the Company hereby covenant
and agree to execute and deliver any additional documents necessary or
desirable, in the reasonable opinion of the Company's legal counsel or the
Shareholder, as the case may be, to carry out the intent of this Agreement.

        8. Consent and Waiver. The Shareholder hereby gives any consent or
waivers that are reasonably required for the consummation of the Merger under
the terms of any agreement to which the Shareholder is a party or pursuant to
any other rights the Shareholder may have.

        9. Miscellaneous.

           9.1 Severability. If any term, provision, covenant or restriction of
this Agreement is held by a court of competent jurisdiction to be invalid, void
or unenforceable, the remainder of the terms, provisions, covenants and
restrictions of this Agreement shall remain in full force and effect and shall
in no way be affected, impaired or invalidated.

           9.2 Binding Effect and Assignment. This Agreement and all of the
provisions hereof shall be binding upon and inure to the benefit of the parties
hereto and their respective successors and permitted assigns, but, except as
otherwise specifically provided herein, neither 


                                       3
<PAGE>   81

this Agreement nor any of the rights, interests or obligations of the parties
hereto may be assigned by any of the parties without the prior written consent
of the other.

           9.3 Amendments and Modifications. This Agreement may not be modified,
amended, altered or supplemented except upon the execution and delivery of a
written agreement executed by the parties hereto.

           9.4 Specific Performance: Injunctive Relief. The parties hereto
acknowledge that the Company will be irreparably harmed and that there will be
no adequate remedy at law for a violation of any of the covenants or agreements
of the Shareholder set forth herein. Therefore, it is agreed that, in addition
to any other remedies which may be available to the Company upon such violation,
the Company shall have the right to enforce such covenants and agreements by
specific performance, injunctive relief or by any other means available to it at

       (including, without limitation, the power to execute and deliver written
       consents with respect to the Shares) of the undersigned at every annual,
       special or adjourned meeting of Wayfarer shareholders, and in every
       written consent in lieu of such a meeting, or otherwise,

<PAGE>   88

                            NONCOMPETITION AGREEMENT


        THIS NONCOMPETITION AGREEMENT is made and entered into this 8th day of
June, 1998, by and between , an individual ("Shareholder"), and The Vantive
Corporation, a Delaware corporation ("Buyer"). For the purposes of this
Agreement, "Buyer" shall be deemed to include Buyer and its majority owned
direct and indirect subsidiaries that operate the Business of Wayfarer (as
hereinafter defined) during the term of this Agreement.

                                    RECITALS

        A. Wayfarer Communications, Inc., a California corporation ("Wayfarer"),
is engaged throughout the United States of America and the world. Wayfarer is in
the business of providing client/server software that extracts and filters
top-line business content in real-time for enterprise desktops (the "Business of
Wayfarer");

        B. Pursuant to that certain Agreement and Plan of Reorganization (the
"Reorganization Agreement") dated June 17, 1998 by and among Buyer, Revo
Acquisition Corporation, a Delaware corporation and wholly-owned subsidiary of
Buyer ("Sub"), and Wayfarer, Buyer is acquiring Wayfarer through a merger of Sub
with and into Wayfarer (the "Merger"). After the Merger becomes effective, the
separate existence of Sub shall cease, and Wayfarer, as the surviving
corporation in the Merger, shall continue its corporate existence under the laws
of the State of California and will continue to operate the Business of Wayfarer
as a wholly-owned subsidiary of Buyer;

        C. Shareholder is the beneficial owner of shares of capital stock of
Wayfarer and is a key employee or officer of Wayfarer;

        D. Shareholder has been actively involved in the design, development
and/or marketing of Wayfarer's products, including the management of a key
function within Wayfarer; and

        E. In consideration of and as an inducement to Buyer and Sub to
consummate the Merger, Shareholder, intending to be bound hereby, has agreed to
execute this Agreement.

        NOW, THEREFORE, the parties agree as follows:

        1. Covenant Not to Compete. Shareholder agrees that, for a period of one
(1) year from the Effective Time of the Merger (as defined in the Reorganization
Agreement) and for so long thereafter as he is employed by or serves as a
consultant to Buyer, or such shorter period ending upon Shareholder's
termination of employment from the Company without "Cause" or 


                                       1
<PAGE>   89

because of "Certain Reasons" (as defined in Section 1(d) and 1(e) hereof,
respectively) (the "Noncompetition Period"), he will not:

        (a)    engage directly or indirectly in Competition;

        (b)    directly or indirectly be or become an officer, director,
shareholder, owner, partner, promoter, employee, agent, consultant, licensor or
joint venturer, of, for or to, or otherwise be or become associated with or
acquire or hold (of record, beneficially or otherwise) any direct or indirect
interest in, any Person that engages directly or indirectly in Competition,
except that Shareholder may be or become an employee, consultant, agent,
licensor or sublicensor of, for or to, or otherwise be or become associated
with, such Person if Shareholder's actual services rendered or activity in
connection with such Person do not reasonably relate to a Competing Product or
Competing Service; or

        (c)    request or advise any of the customers, suppliers or other 
business contacts of Wayfarer with which Shareholder had contact while employed
by Wayfarer to withdraw, curtail, cancel or not increase their business with
Wayfarer. Notwithstanding the foregoing, Shareholder is permitted to own as a
passive investor up to a three (3%) interest in any publicly traded entity.
Shareholder agrees to notify Buyer in writing of each employment or consulting
position he accepts during the Noncompetition Period (including the name and
address of the hiring party) and will, upon request by Buyer, describe in
reasonable detail the nature of his duties in each such position.

        (d)    "Cause" shall mean Shareholder's:

               (i)       failure to perform such assigned duties and 
responsibilities as shall be consistent with the duties and responsibilities of
an employee of Wayfarer in a similar job position after receipt of a written
notice of specific deficiencies consistent with Buyer's performance review
policies in effect at such time and a reasonable period not to exceed thirty
(30) days for Shareholder to cure any such deficiencies;

               (ii)      engaging in gross negligence or willful misconduct 
which is or is likely to be materially injurious to Wayfarer;

               (iii)     committing a felony, an act of fraud against, or the
misappropriation of property belonging to Wayfarer; or

               (iv)      breaching in any material respect the terms of any
employment agreement or any confidential or proprietary information agreement
between Shareholder and Wayfarer or Buyer; and


                                       2
<PAGE>   90

               (v)  a majority vote of the Board of Directors of Buyer 
authorizes a for Cause termination after the occurrence of any of the events
described in clauses (i), (ii), (iii) or (iv) as set forth above.

        (e)    "Certain Reasons" shall mean (i) a reduction in cash compensation
(exclusive of bonuses) or a material reduction in benefits, except as part of a
salary or benefit reduction program by Buyer that is applicable generally to
employees of Shareholder's level, (ii) assignment to a position materially not
commensurate with Shareholder's training and abilities, or (iii) relocation of
Shareholder's workplace to any place more than fifty miles from Mountain View,
California, provided, in each case, that Shareholder has given Buyer written
notice of Shareholder's intention to terminate for Certain Reasons, citing the
Certain Reasons, and Wayfarer has not cured the Certain Reasons within thirty
(30) days after receipt of such notice.

        (f)    "Competing Product" means client/server software that extracts 
and filters top-line business content in real time for enterprise desktops or
any other product that is substantially the same as, is based upon or competes
in any material respect with such products.

        (g)    "Competing Service" means any: (i) activities relating to the
development, marketing and/or distribution of Competing Products carried on by
any business worldwide which competes with the Business of Wayfarer; (ii)
service that has been provided, performed or offered by or on behalf of Wayfarer
at any time on or prior to the date of this Noncompetition Agreement; (iii)
service that facilitates, supports or otherwise relates to the design,
development, marketing, promotion, sale, supply distribution, resale,
installation, support, maintenance, license or sublicense of any Competing
Product; or (iv) service that is substantially the same as, is based upon or
competes in any material respect with any service referred to in clause (i),
(ii) or (iii) of this sentence.

        (h)    "Competition": a Person shall be deemed to be engaged in
"Competition" if: (a) such Person is engaged in the design, development,
marketing, promotion, sale, supply, distribution, resale, installation, support,
maintenance, license or sublicense of any Competing Product; or (b) such Person
is engaged in providing, performing or offering any Competing Service.
References to engaging directly or indirectly in Competition include (without
prejudice to the generality of that expression) references to acting alone or
jointly with or by means of any other Person.

        (i)    "Person" means any: (i) individual; (ii) corporation, general
partnership, limited partnership, limited liability partnership, trust, company
(including any limited liability company or joint stock company) or other
organization or entity; or (iii) governmental body or authority.

        2.     Covenant Not to Hire. During the Noncompetition Period, 
Shareholder agrees that he will not directly or indirectly hire or attempt to
hire, whether as an employee, consultant


                                       3
<PAGE>   91

or otherwise, any person who at such time is, or who at any time in the six (6)
month period prior to such time had been, employed by Buyer or Wayfarer.

        3.     Nondisruption; Other Matters. During the Noncompetition Period,
Shareholder agrees that he will not directly or indirectly interfere with,
disrupt or attempt to disrupt any past, present or prospective relationship,
contractual or otherwise, between Buyer or Wayfarer, on the one hand, and any of
their respective customers, suppliers or employees, on the other hand.

        4.     Equitable Relief. Shareholder acknowledges and agrees that 
Buyer's remedies at law for breach of any of the provisions of this Agreement
would be inadequate and, in recognition of this fact, Shareholder agrees that,
in the event of such breach, in addition to any remedies at law it may have,
Buyer, without posting any bond, shall be entitled to obtain equitable relief in
the form of specific performance, a temporary restraining order, a temporary or
permanent injunction or any other equitable remedy that may be available.
Shareholder further acknowledges that should Shareholder violate any of the
provisions of this Agreement, it will be difficult to determine the amount of
damages resulting to Buyer and that in addition to any other remedies it may
have, Buyer shall be entitled to temporary and permanent injunctive relief
without the necessity of proving damages.

        5.     Acknowledgment. Each of Shareholder and Buyer acknowledges and 
agrees that the covenants and agreements contained in this Agreement have been
negotiated in good faith by the parties, are reasonable and are not more
restrictive or broader than necessary to protect the interests of the parties
thereto, and would not achieve their intended purpose if they were on different
terms or for periods of time shorter than the periods of time provided herein or
applied in more restrictive geographical areas than are provided herein. Each
party further acknowledges that Buyer would not enter into the Reorganization
Agreement and the transactions contemplated thereby in the absence of the
covenants and agreements contained in this Agreement and that such covenants and
agreements are essential to protect the value of Wayfarer to Buyer.

        6.     Separate Covenants. The covenants contained in this Agreement 
shall be construed as a series of separate covenants, one for each of the
counties in each of the states of the United States of America one for each
province of Canada, and one for each country outside the United States and
Canada.

        7.     Severability. The parties agree that construction of this 
Agreement shall be in favor of its reasonable nature, legality and
enforceability, and that any construction causing unenforceability shall yield
to a construction permitting enforceability. It is agreed that the
noncompetition, nonsolicitation, and nonhiring covenants and provisions of this
Agreement are severable, and that if any single covenant or provision or
multiple covenants or provisions should be found unenforceable, the entire
Agreement and remaining covenants and provisions shall not fail but shall be
construed as enforceable without any severed covenant or provision in accordance
with the tenor of this Agreement. The parties specifically agree that no
covenant or 


                                       4
<PAGE>   92

provision of this Agreement shall be invalidated because of overbreadth insofar
as the parties acknowledge the scope of the covenants and provisions contained
herein to be reasonable and necessary for the protection of Buyer and Wayfarer
and not unduly restrictive upon Shareholder. However, should a court or any
other trier of fact or law determine not to enforce any covenant or provision of
this Agreement as written due to overbreadth, then the parties agree that said
covenant or provision shall be enforced to the extent reasonable, with the court
or such trier to make any necessary revisions to said covenant or provision to
permit its enforceability.

        8.     Not an Employment Agreement. This Agreement is not, and nothing 
in this Agreement shall be construed as, an agreement to provide employment to
Shareholder.

        9.     Governing Law. This Agreement is made under and shall be governed
by, construed in accordance with and enforced under the internal laws of the
State of California. All disputes arising under this Agreement shall be brought
in the federal and state courts located in Santa Clara County, California, as
permitted by law, and each of the parties hereby consents to the personal
jurisdiction, service of process and venue of such courts.

        10.    Entire Agreement. This Agreement, together with the 
Reorganization Agreement, constitutes and contains the entire agreement and
understanding concerning the subject matter addressed herein between the
parties, and supersedes and replaces all prior negotiations and all agreements
proposed or otherwise, whether written or oral, concerning the subject matter
hereof, and the parties hereto have made no agreements, representations or
warranties relating to the subject matter of this Agreement that are not set
forth herein or in the Reorganization Agreement.

        11.    Notices. Any notice or other communication under this Agreement
shall be in writing, signed by the party making the same, and shall be delivered

other than that specifically waived.

        14.    Assignment. This Agreement may be assigned by Buyer to any 
affiliate of Buyer or to any nonaffiliate of Buyer that shall succeed to the
business and assets of Buyer, Wayfarer and the Business of Wayfarer. In the
event of any such assignment, Buyer shall cause such affiliate or nonaffiliate,
as the case may be, to assume the obligations of Buyer hereunder, by a written
agreement addressed to Shareholder, concurrently with any assignment with the
same effect as if such assignee were "Buyer" hereunder. This Agreement is
personal to Shareholder, and Shareholder may not assign any rights or delegate
any responsibilities hereunder.

        15.    Headings. The headings of paragraphs in this Agreement are solely
