Inc., a California corporation and wholly-owned subsidiary of Siebel ("Merger
Sub"), and Scopus, and subject to the conditions set forth therein (including
approval by the stockholders of Siebel and Scopus), Merger Sub will be merged
with and into Scopus (the "Merger"), with each share of Scopus Common Stock
being converted into the right to receive 0.36405 shares of common stock, par
value $.001 per share, of Siebel ("Siebel Common Stock") (as adjusted for any
stock split, stock dividend, reverse stock split, reclassification,
recapitalization or other similar transaction) (the "Exchange Ratio"). After
giving effect to the 100% dividend on Siebel Common Stock to be paid on March
20, 1998, the Exchange Ratio would be 0.7281. The description contained in this

 ITEM 4.   PURPOSE OF TRANSACTION 

  (a)  - (b)   As described in Item 3 above, this statement relates to the
merger of Merger Sub, a wholly-owned subsidiary of Siebel, with and into Scopus
in a statutory merger pursuant to the California General Corporation Law
("California Law").  At the effective time of the Merger (the "Effective Time"),
the separate existence of Merger Sub will cease and Scopus will continue as the
surviving corporation and as a wholly-owned subsidiary of Siebel ("Surviving
Corporation").  The officers and directors of the Surviving Corporation after
the Effective Time shall be as mutually determined by Scopus and Siebel prior to
the Effective Time and shall serve as the officers and directors of the
Surviving Corporation until their respective successors are elected and
qualified or duly appointed, as the case may be.  The Articles of Incorporation
of the Surviving Corporation shall be amended and restated as of the Effective
Time to conform to the Articles of Incorporation of Merger Sub as in effect
immediately prior to the Effective Time; provided, however, that at the
Effective Time the Articles of Incorporation of the Surviving Corporation shall
be amended so that the name of the Surviving Corporation shall be Scopus
Technology, Inc.  The Bylaws of the Surviving Corporation shall be amended and
restated as of the Effective Time to conform to the Bylaws of Merger Sub as in
effect immediately prior to the Effective Time.

     Merger Consideration.  In connection with the Merger, holders of
     ---------------------                                           
outstanding Scopus Common Stock will receive, in exchange for each share of
Scopus Common Stock held by them, 0.36405 shares of Siebel Common Stock (as
adjusted for any stock split, stock dividend, reverse stock split,
reclassification, recapitalization or other similar transaction) (i.e., the
Exchange Ratio). After giving effect to the 100% dividend on Siebel Common Stock
to be paid on March 20, 1998, the Exchange Ratio would be 0.7281. In addition,
Siebel will assume all options outstanding under Scopus' 1991 Stock Option Plan
and the Director Stock Option Plan. In accordance with the terms of the 
Reorganization Agreement, Siebel and Scopus will mutually agree as to the 
treatment of Scopus' Employee Stock Purchase Plan. If the Merger is
consummated, Scopus Common Stock will be deregistered under the Exchange Act and
delisted from the Nasdaq National Market.

     Representations, Warranties, Covenants and Closing Conditions.  The
     -------------------------------------------------------------      
Reorganization Agreement contains customary representations and warranties on
the part of Scopus and Siebel, and the consummation of the Merger is subject to
customary closing conditions, including, without limitation, approval by the
stockholders of Scopus and Siebel, regulatory approval and the occurrence of no
material adverse effect with respect to a party.  The Reorganization Agreement
also contains covenants regarding the activities of Scopus and Siebel prior to
the earlier of the Effective Time and the termination of the Reorganization
Agreement.  Scopus has agreed to conduct its business in the ordinary course, in
a commercially reasonable manner and in compliance with applicable laws.  In
addition, a number of corporate actions by Scopus during the period pending the
closing of the Merger require Siebel's approval, including borrowings, capital
expenditures and stock option grants above specified minimums.  Siebel has
agreed not to take, without Scopus' prior written consent, certain actions, such
as payment of extraordinary dividends or other distributions to shareholders if
they would be materially adverse to the shareholders of Scopus compared to the
stockholders of Siebel.

     Termination of the Merger Agreement.  The Reorganization Agreement may be
     -----------------------------------                                      
terminated prior to the Effective Time, whether before or after approval of the
Merger by the stockholders of Siebel and the shareholders of Scopus: (i) by
mutual written consent of the Boards of Directors of Siebel and Scopus; (ii)
subject to certain exceptions, by either Siebel or Scopus if the Merger shall
not have been consummated by September 1, 1998; (iii) by either Siebel or Scopus
in connection with certain legal or governmental actions having the effect of
permanently restraining, enjoining or otherwise prohibiting the Merger; (iv)
subject to certain limitations, by Siebel or Scopus if the Scopus Special
Meeting shall have been held and the Reorganization Agreement and the Merger
shall not have been approved by the necessary vote of the Scopus shareholders;
(v) by Siebel or Scopus if (at any time prior to the adoption and approval of
the Reorganization Agreement and approval of the Merger by the Scopus
shareholders) a "Triggering Event" (as defined in the Reorganization Agreement)
shall have occurred (provided that Scopus shall not have the right to terminate
on this basis until May 30, 1988); (vi) by Siebel or Scopus if (at any time
prior to the adoption and approval of the Reorganization Agreement and approval
of the Merger by the Scopus shareholders) a "Termination Event" (as defined in
the Reorganization Agreement) shall have occurred (provided that Scopus shall
not have the right to terminate on this basis until May 30, 1988); (vii) subject
to certain limitations, by Siebel or Scopus if the Siebel Special Meeting shall
have been

held and the issuance of Siebel Common Stock in the Merger shall not have been
approved by the necessary vote of the Siebel stockholders; (viii) by Siebel if
Scopus' representations and warranties in the Reorganization Agreement shall be
or become materially inaccurate or if any of Scopus' covenants in the
Reorganization Agreement shall have been breached and not cured within the
period required by the Merger Agreement; or (ix) by Scopus if Siebel's
representations and warranties in the Reorganization Agreement shall be or
become materially inaccurate or if any of Siebel's covenants in the
Reorganization Agreement shall have been breached and not cured within the
period required by the Merger Agreement.

Expiration Date, they will vote their shares of Scopus Common Stock in favor of:
(i) approval of the Merger; (ii) approval and adoption of the Reorganization

delivered to Siebel irrevocable proxies with respect to the matters covered by
the Scopus Voting Agreements.  In addition, subject to certain de minimis
exceptions, the Scopus Voting Agreement Shareholders have agreed not to transfer
any securities of Scopus owned by them unless and until the proposed transferee
of such Scopus securities shall have (i) executed a counterpart of the Scopus
Voting Agreement and an irrevocable proxy and (ii) agreed to hold such Scopus
securities subject to all of the terms and provisions of the Scopus Voting
Agreement. Siebel did not pay any additional consideration to any Scopus Voting
Agreement Shareholders in connection with the execution and delivery of the
Scopus Voting Agreements.  The description contained in this Item 4 of the
transactions contemplated by the Scopus Voting Agreements is qualified in its
entirety by reference to the full text of the form of Scopus Voting Agreement, a

(individually, a "Siebel Voting Agreement" and, collectively, the Siebel Voting

     Affiliate Agreements.  In connection with the Reorganization Agreement,
     --------------------                                                   
Scopus has covenanted to deliver to Siebel agreements ("Scopus Affiliate
Agreements") executed by each of the Scopus Voting Agreement Stockholders (each
a "Scopus Affiliate") whereby each Scopus Affiliate agrees not to effect any
sale, transfer or other disposition of the Siebel Common Stock received by such
Scopus Affiliate in the Merger unless: (i) such sale, transfer or other
disposition is made in conformity with the volume and other requirements of Rule
145 under the Securities Act, as evidenced by a broker's letter and a
representation letter executed by the Scopus Affiliate (reasonably satisfactory
in form and content to Siebel), each stating that such requirements have been
met; (ii) legal counsel reasonably satisfactory to Siebel shall have advised
Siebel in a written opinion letter (reasonably satisfactory in form and content
to Siebel), upon which Siebel may rely, that such sale, transfer or other
disposition will be exempt from registration under the Securities Act; (iii)
such sale, transfer or other disposition is effected pursuant to an effective
registration statement under the Securities Act; or (iv) an authorized
representative of the Commission shall have rendered written advice to such
Scopus Affiliate to the effect that the Commission would take no action, or that
the staff of the Commission would not recommend that the Commission take action,
with respect to such proposed sale, transfer or other disposition, and a copy of
such written advice and all other related communications with the Commission
shall have been delivered to Siebel.

     In addition, so as to help ensure that the Merger will be treated as a
pooling of interests for accounting and financial reporting purposes, the Scopus
Affiliate Agreements provide that during the period contemplated by the
Commission's Staff Accounting Bulletin Number 65 until the earlier of (i)
Siebel's public announcement of financial results covering at least 30 days of
combined operations of Siebel and Scopus or (ii) the Reorganization Agreement is
terminated in accordance with its terms, no Scopus Affiliate shall sell,
exchange, transfer, pledge, distribute or otherwise dispose of or grant any
option, establish any "short" or put-equivalent position with respect to or
enter into any similar transaction (through derivative's or otherwise) intended
or having the effect, directly or indirectly, to reduce such Scopus Affiliate's
risk relative to:  (i) any Scopus Common Stock (except pursuant to and upon
consummation of the Merger); or (ii) any Siebel Common Stock received by such
Scopus Affiliate in the Merger or upon exercise of options assumed by Siebel in
the Merger.  Provided certain conditions are met, the Scopus Affiliate
Agreements provide for certain exceptions to the foregoing restrictions on
transfer relating to:  (i) certain de minimis transfers; (ii) transfers in
payment of the exercise price of options to purchase Scopus Common Stock or
Siebel Common Stock; (iii) charitable donations; or (iv) transfers to trusts
established for the benefit of members of such Scopus Affiliate's family or
gifts to members of such Scopus Affiliate's family. The description contained in
this Item 4 of the transactions contemplated by the Scopus Affiliate Agreements
is qualified in its entirety by reference to the full text of the form of Scopus
Affiliate Agreement, a copy of which is attached to this Schedule 13D as Exhibit
99.4

     Also in connection with the Reorganization Agreement, Siebel has covenanted
to deliver to Scopus agreements ("Siebel Affiliate Agreements") executed by each
of the Siebel Voting Agreement Stockholders (each a "Siebel Affiliate")
providing that, during the period contemplated by the Commission's Staff
Accounting Bulletin Number 65 until the earlier of (i) Siebel's public
announcement of financial results covering at least 30 days of combined
operations of Siebel and Scopus or (ii) the Reorganization Agreement is
terminated in accordance with its terms, no Siebel Affiliate shall, subject to
certain exceptions, sell, exchange, transfer, pledge, distribute or otherwise
dispose of or grant any option, establish any "short" or put-equivalent position
with respect to or enter into any similar transaction (through derivative's or
otherwise) intended or having the effect, directly or indirectly, to reduce such
Siebel Affiliate's risk relative to any Siebel Common Stock.  Provided certain

     Stock Option Agreement.  Also as an inducement to Siebel to enter into the
     ----------------------                                                    
Reorganization Agreement, Siebel and Scopus entered into a Stock Option
Agreement dated March 1, 1998 (the "Option Agreement") pursuant to which Scopus
granted Siebel the right under certain conditions to purchase up to 3,493,879
shares of Scopus Common Stock (the "Option Shares") at a purchase price of
$20.00 per share (the "Option").  Subject to certain conditions, the option
granted in the Option Agreement may be exercised, in whole or in part, on any
one occasion,  if a "Triggering Event" (as defined in the Reorganization
Agreement) has occurred;  provided, however, that in the event the Option
becomes exercisable for this reason, the Option shall terminate upon the
earliest to occur of: (i) the Effective Time of the Merger; (ii) 270 days after
the first occurrence of a Triggering Event; and (iii) the valid termination of
the Reorganization Agreement in accordance with its terms prior to the
occurrence of a Triggering Event.  In addition,  if (i) the special meeting of
Scopus shareholders to consider, approve and adopt the Merger and the
Reorganization Agreement (the "Scopus Special Meeting") shall have been held and
the Merger and the Reorganization Agreement shall not have been adopted and
approved by the necessary vote of the Scopus shareholders, (ii) following the
date of the Reorganization Agreement and prior to the Scopus Special Meeting, an
"Acquisition Proposal" (as defined in the Reorganization Agreement) shall have
been publicly announced, and (iii) on or prior to the first anniversary of the
termination of the Reorganization Agreement, Siebel shall have entered into a
definitive agreement providing for a "Company Acquisition" (as defined in the
Reorganization Agreement"), then the Option may be exercised by Siebel, in whole
or in part, on any one occasion and at any time following the date of such
definitive agreement relating to a Company Acquisition (or the consummation of a
Company Acquisition if there is no definitive agreement) and prior to the date
180 days following the date of such definitive agreement relating to a Company
Acquisition (or 180 days after the consummation of a Company Acquisition if
there is no definitive agreement).

     Siebel has agreed that in the event that the Option becomes exercisable and
the Option or the Scopus Common Stock (or any rights therein) subject to the
Option are sold, transferred or otherwise disposed of by Siebel at any time
within the subsequent ten years, Siebel shall pay to Scopus the amount by which
any "Proceeds" (as defined in the Option Agreement) from such transaction
exceeds the "Aggregate Cost Amount" (as defined in the Option Agreement) of the
Option or the Scopus Common Stock so transferred, as applicable (and including
interest on the aggregate purchase price of the Scopus Common Stock if Scopus
Common Stock is transferred).  In addition, during the 180 day period commencing
with the date 270 days following the acquisition by Siebel of any Scopus Common
Stock issuable pursuant to the Option, Scopus may repurchase such Scopus Common
Stock at a price equal to the aggregate exercise price plus interest from the
date such Scopus Common Stock was acquired.  Scopus has also granted Siebel
certain rights to require Scopus to register the Scopus Common Stock acquired
pursuant to the Option under the Securities Act. The description contained in
this Item 4 of the transactions contemplated by the Option Agreement is
qualified in its entirety by reference to the full text of the Option Agreement,
a copy of which is attached to this Schedule 13D as Exhibit 99.6.

     (c)  Not applicable.

     (d)  If the Merger is consummated, Scopus will become a wholly-owned
subsidiary of Siebel and Siebel will subsequently determine the size and
membership of the Board of Directors of Scopus and the officers of Scopus.

     (e)  None, other than a change in the number of outstanding shares of
Scopus Common Stock as contemplated by the Reorganization Agreement.

     (f)  Upon consummation of the Merger, Scopus will become a wholly-owned
subsidiary of Siebel.

     (g)  Upon consummation of the Merger, the Articles of Incorporation of
Scopus will be amended and restated in a form satisfactory to Siebel.

     (h)  Upon consummation of the Merger, the Scopus Common Stock will cease to
be quoted on any quotation system or exchange.

     (i) Upon consummation of the Merger, the Scopus Common Stock will become
eligible for termination of registration pursuant to Section 12(g)(4) of the
Exchange Act.

     (j) Other than as described above, Siebel currently has no plan or proposal
which relates to, or may result in, any of the matters listed in Items 4(a) -
(i) of Schedule 13D (although Siebel reserves the right to develop such plans).

ITEM 5.   INTEREST IN SECURITIES OF THE ISSUER

  (a)  - (b)   As a result of the Scopus Voting Agreements, Siebel has shared
power to vote an aggregate of 5,257,000 shares of Scopus Common Stock for the
limited purposes described in Item 4 above.  As a result of the Option Agreement
granted to Siebel, Siebel may be deemed to be the beneficial owner of an
additional 3,493,879 shares of Scopus Common Stock (assuming exercise of the
Option as described in Item 4 above).  In the aggregate, such shares
(representing a total of 8,750,879 shares of Scopus Common Stock) would
represent approximately 36.12% of the shares of Scopus Common Stock outstanding
as of December 31, 1997 after giving effect to the exercise of the Option.

     To Siebel's knowledge, no shares of Scopus Common Stock are beneficially
owned by any of the persons named in Schedule I, except for such beneficial
ownership, if any, arising solely from the Scopus Voting Agreements and the 
Option Agreement.

     Set forth in Schedule IV to this Schedule 13D is the name and present
principal occupation or employment of each person with whom Siebel shares the
power to vote or to direct the vote or to dispose or direct the disposition of
Scopus Common Stock.

     During the past five years, to Siebel's knowledge, no person named in
Schedule IV to this Schedule 13D has been convicted in a criminal proceeding
(excluding traffic violations or similar misdemeanors).

     During the past five years, to Siebel's knowledge, no person named in
Schedule IV to this Schedule 13D was a party to a civil proceeding of a judicial
or administrative body of competent jurisdiction as a result of which such
person was or is subject to a judgment, decree or final order enjoining future
violations of or prohibiting or mandating activity subject to federal or state
securities laws or finding any violation with respect to such laws.

     To Siebel's knowledge, all persons named in Schedule IV to this Scheduled
13D are citizens of the United States.

     (c)  Neither Siebel, nor, to Siebel's knowledge, any person named in
Schedule IV, has effected any transaction in Scopus Common Stock during the past
60 days, except as disclosed herein.

     (d)  Not applicable.

     (e)  Not applicable.

ITEM 6.   CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH RESPECT
          TO SECURITIES OF THE ISSUER

     Other than as described in Item 4 above, to Siebel's knowledge, there are
no contracts, arrangements, understandings or relationships (legal or otherwise)
among the persons named in Item 2 and between such persons and any person with
respect to any securities of Scopus, including but not limited to transfer or
voting of any of the securities, finder's fees, joint ventures, loan or option
arrangements, puts or calls, guarantees of profits, division of profits or loss,
or the giving or withholding of proxies.

                               AGREEMENT AND PLAN
                                       OF
                           MERGER AND REORGANIZATION

Merger is consistent with and in furtherance of the long-term strategy of the
Company and fair to, and in the best interests of, the Company and its

approve the Merger.

     D.  The respective Boards of Directors of Parent and Merger Sub have
approved this Agreement and the Merger.

     E.  Concurrently with the execution of this Agreement, and as a condition
and inducement to Parent's willingness to enter into this Agreement, each of the
affiliate shareholders of the Company listed on Exhibit B-1 hereto is entering
into a Voting Agreement substantially in the form attached hereto as Exhibit C-
1; and as a condition and inducement to the Company's willingness to enter into
this Agreement, the affiliate stockholder of Parent listed on Exhibit B-2 hereto
is entering into a Voting Agreement substantially in the form attached hereto as
Exhibit C-2.

     F.  Concurrently with the execution of this Agreement, and as a condition
and inducement to Parent's willingness to enter into this Agreement, the Company
is entering into an Option Agreement substantially in the form attached hereto
as Exhibit D.

                                   AGREEMENT

          The parties to this Agreement, intending to be legally bound, agree as
follows:

SECTION 1. DESCRIPTION OF TRANSACTION.

       1.1  MERGER OF MERGER SUB INTO THE COMPANY. Upon the terms and subject
to the conditions set forth in this Agreement, at the Effective Time (as defined
in Section 1.3), Merger Sub shall be merged with and into the Company, and the
separate existence of Merger Sub shall cease. The Company will continue as the
surviving corporation in the Merger (the "SURVIVING CORPORATION").

       1.2  EFFECT OF THE MERGER. The Merger shall have the effects set forth in
this Agreement and in the applicable provisions of the CGCL.

       1.3  CLOSING; EFFECTIVE TIME. The consummation of the transactions
contemplated by this Agreement (the "CLOSING") shall take place at the offices
of Cooley Godward llp, Five Palo Alto Square, 3000 El Camino Real, Palo Alto,
California, at 10:00 a.m. on a date to be designated by Parent (the "CLOSING
DATE"), which shall be no later than the second business day after satisfaction
or waiver of the conditions set forth in Sections 6 and 7. Contemporaneously
with or as promptly as practicable after the Closing, a properly executed
agreement of merger conforming to the requirements of the CGCL (the "AGREEMENT
OF MERGER") shall be filed with the Secretary of State of the State of
California. The Merger shall take effect at (a) the time the Agreement of Merger
is filed with the Secretary of State of the State of California or (b) at such
later time as may be as agreed by the parties and as may be specified in the
Agreement of Merger (the "EFFECTIVE TIME").

       1.4  CERTIFICATE OF INCORPORATION AND BYLAWS; DIRECTORS AND OFFICERS.
Unless otherwise determined by Parent prior to the Effective Time:

            (a) the Articles of Incorporation of the Surviving Corporation shall
be amended and restated as of the Effective Time to conform to the Articles of
Incorporation of Merger Sub as in effect immediately prior to the Effective
Time; provided, however, that at the Effective Time the Articles of
Incorporation of the Surviving Corporation shall be amended so that the name of
the Surviving Corporation shall be Scopus Technology, Inc.;

            (b) the Bylaws of the Surviving Corporation shall be amended and
restated as of the Effective Time to conform to the Bylaws of Merger Sub as in
effect immediately prior to the Effective Time; and

            (c) the directors and officers of the Surviving Corporation
immediately after the Effective Time shall be as mutually determined by Parent
and Company prior to the Effective Time, and shall serve until their respective
successors are elected and qualified or duly appointed, as the case may be.

                                      2.

     1.5  CONVERSION OF SHARES.

          (a) Subject to Section 1.5(d), at the Effective Time, by virtue of the
Merger and without any further action on the part of Parent, Merger Sub, the
Company or any shareholder of the Company:

              (i)   any shares of Company Common Stock then held by the Company
or any subsidiary of the Company (or held in the Company's treasury) shall be
canceled;

              (ii)  any shares of Company Common Stock then held by Parent,
Merger Sub or any other subsidiary of Parent shall be canceled;

              (iii) except as provided in clauses "(i)" and "(ii)" above and
subject to Section 1.5(b), each share of Company Common Stock then outstanding
shall be converted into the right to receive 0.36405 of a share of Parent Common
Stock; and

              (iv)  each share of the common stock, no par value per share, of
Merger Sub then outstanding shall be converted into one share of common stock of
the Surviving Corporation.

          (b) The fraction of a share of Parent Common Stock into which each
outstanding share of Company Common Stock is to be converted pursuant to Section
1.5(a)(iii) (as such fraction may be adjusted in accordance with this Section
1.5(b)) is referred to as the "EXCHANGE RATIO."  If, between the date of this
Agreement and the Effective Time, the outstanding shares of Company Common Stock
or Parent Common Stock are changed into a different number or class of shares by
reason of any stock split, stock dividend, reverse stock split,
reclassification, recapitalization or other similar transaction, then the
Exchange Ratio shall be appropriately adjusted.

          (c) If any shares of Company Common Stock outstanding immediately
prior to the Effective Time are unvested or are subject to a repurchase option,
risk of forfeiture or other condition under any applicable restricted stock
purchase agreement or other agreement with the Company, then the shares of
Parent Common Stock issued in exchange for such shares of Company Common Stock
will also be unvested and subject to the same repurchase option, risk of
forfeiture or other condition, and the certificates representing such shares of
Parent Common Stock may accordingly be marked with appropriate legends.  The
Company shall take all action that may be necessary to ensure that, from and
after the Effective Time, Parent is entitled to exercise any such repurchase
option or other right set forth in any such restricted stock purchase agreement
or other agreement.

          (d) No fractional shares of Parent Common Stock shall be issued in
connection with the Merger, and no certificates for any such fractional shares
shall be issued.  In lieu of such fractional shares, any holder of Company
Common Stock who would otherwise be entitled to receive a fraction of a share of
Parent Common Stock (after aggregating all fractional shares of Parent Common
Stock issuable to such holder) shall, upon surrender of such holder's Company
Stock Certificate(s) (as defined in Section 1.7), be paid in cash the dollar
amount (rounded to the nearest whole cent), without interest, determined by
multiplying such fraction by the closing price of a share of Parent Common Stock
on Nasdaq on the Closing Date.

                                      3.
<PAGE>
 
     1.6  STOCK OPTIONS. At the Effective Time, all Company Options (as defined
in Section 2.3(b)) and rights to acquire shares of Company Common Stock under
the Purchase Plan (as defined in Section 2.3(b)) shall be assumed by Parent in
accordance with Section 5.5.

     1.7  CLOSING OF THE COMPANY'S TRANSFER BOOKS. At the Effective Time: (a)
all shares of Company Common Stock outstanding immediately prior to the
Effective Time shall automatically be canceled and retired and shall cease to
exist, and all holders of certificates representing shares of Company Common
Stock that were outstanding immediately prior to the Effective Time shall cease
to have any rights as shareholders of the Company; and (b) the stock transfer
books of the Company shall be closed with respect to all shares of Company
Common Stock outstanding immediately prior to the Effective Time. No further
transfer of any such shares of Company Common Stock shall be made on such stock
transfer books after the Effective Time. If, after the Effective Time, a valid
certificate previously representing any of such shares of Company Common Stock
(a "COMPANY STOCK CERTIFICATE") is presented to the Exchange Agent (as defined
in Section 1.8) or to the Surviving Corporation or Parent, such Company Stock
Certificate shall be canceled and shall be exchanged as provided in Section 1.8.

     1.8  EXCHANGE OF CERTIFICATES.

          (a) Prior to the Closing Date, Parent shall select a reputable bank or
trust company to act as exchange agent in the Merger (the "EXCHANGE AGENT").
Promptly after the Effective Time, Parent shall deposit with the Exchange Agent
(i) certificates representing the shares of Parent Common Stock issuable
pursuant to this Section 1 and (ii) cash sufficient to make payments in lieu of
fractional shares in accordance with Section 1.5(d).  The shares of Parent
Common Stock and cash amounts so deposited with the Exchange Agent, together
with any dividends or distributions received by the Exchange Agent with respect
to such shares, are referred to collectively as the "EXCHANGE FUND."

          (b) As soon as practicable after the Effective Time, the Exchange
Agent will mail to the registered holders of Company Stock Certificates (i) a
letter of transmittal in customary form and containing customary provisions
(including a provision confirming that delivery of Company Stock Certificates
shall be effected, and risk of loss and title to Company Stock Certificates
shall pass, only upon delivery of such Company Stock Certificates to the
Exchange Agent), and (ii) instructions for use in effecting the surrender of
Company Stock Certificates in exchange for certificates representing Parent
Common Stock.  Subject to Section 1.5(d), upon surrender of a Company Stock
Certificate to the Exchange Agent for exchange, together with a duly executed
letter of transmittal and such other documents as may be reasonably required by
the Exchange Agent or Parent, (A) the holder of such Company Stock Certificate
shall be entitled to receive in exchange therefor a certificate representing the
number of shares of Parent Common Stock that such holder has the right to
receive pursuant to the provisions of Section 1.5(a)(iii) together with any cash
in lieu of fractional share(s) pursuant to the provisions of Section 1.5(d), and
(B) the Company Stock Certificate so surrendered shall be canceled.  Until
surrendered as contemplated by this Section 1.8(b), each Company Stock
Certificate shall be deemed, from and after the Effective Time, to represent
only the right to receive shares of Parent Common Stock (and cash in lieu of any
fractional share of Parent Common Stock) as contemplated by Section 1.5. If any
Company Stock Certificate shall have been lost, stolen or destroyed, Parent may,
in its discretion and as a condition precedent to the 

                                      4.
<PAGE>
 
issuance of any certificate representing Parent Common Stock, require the owner
of such lost, stolen or destroyed Company Stock Certificate to provide an
appropriate affidavit and to deliver a bond (in such sum as Parent may
reasonably direct) as indemnity against any claim that may be made against the
Exchange Agent, Parent or the Surviving Corporation with respect to such Company
Stock Certificate.

            (c) No dividends or other distributions declared or made with
respect to Parent Common Stock with a record date after the Effective Time shall
be paid to the holder of any unsurrendered Company Stock Certificate with
respect to the shares of Parent Common Stock represented thereby, until such
holder surrenders such Company Stock Certificate in accordance with this Section
1.8 (at which time such holder shall be entitled to receive all such dividends
and distributions, without interest).

            (d) Any portion of the Exchange Fund that remains undistributed to
holders of Company Stock Certificates as of the date 180 days after the date on
which the Merger becomes effective shall be delivered to Parent upon demand, and
any holders of Company Stock Certificates who have not theretofore surrendered
their Company Stock Certificates in accordance with this Section 1.8 shall
thereafter look only to Parent (or its successor, if any) for satisfaction of
their claims for Parent Common Stock, cash in lieu of fractional shares of
Parent Common Stock and any dividends or distributions with respect to Parent
Common Stock.

            (e) Each of the Exchange Agent, Parent and the Surviving Corporation
shall be entitled to deduct and withhold from any consideration payable or
otherwise deliverable pursuant to this Agreement to any holder or former holder
of Company Common Stock such amounts as may be required to be deducted or
withheld therefrom under the Code or under any provision of state, local or
foreign tax law or under any other applicable Legal Requirement.  To the extent
such amounts are so deducted or withheld, such amounts shall be treated for all
purposes under this Agreement as having been paid to the Person to whom such
amounts would otherwise have been paid.

            (f) Neither Parent nor the Surviving Corporation shall be liable to
any holder or former holder of Company Common Stock with respect to any shares
of Parent Common Stock (or dividends or distributions with respect thereto), or
for any cash amounts, delivered to any public official pursuant to any
applicable abandoned property, escheat or similar Legal Requirement.

       1.9  DISSENTING SHARES. Notwithstanding anything to the contrary
contained in this Agreement, any shares of Company Common Stock outstanding
immediately prior to the Effective Time that are or may become "dissenting
shares" within the meaning of Section 1300(b) of the CGCL ("DISSENTING SHARES")
shall not be converted into or represent the right to receive Parent Common
Stock in accordance with Section 1.5(a)(iii) (or cash in lieu of fractional
shares in accordance with Section 1.5(d)), and each holder of Dissenting Shares
shall be entitled only to such rights as may be granted to such holder under
Chapter 13 of the CGCL. From and after the Effective Time, a holder of
Dissenting Shares shall not be entitled to exercise any of the voting rights or
other rights of a shareholder of the Surviving Corporation. If any holder of
Dissenting Shares shall fail to assert or perfect, or shall waive, rescind,
withdraw or otherwise lose, such holder's right to dissent and obtain payment
under Chapter 13 of the CGCL, then such 

                                      5.
<PAGE>
 
shares shall automatically be converted into and shall represent only the right
to receive (upon the surrender of Company Stock Certificate(s) previously
representing such shares) Parent Common Stock in accordance with Section
1.5(a)(iii) (and cash in lieu of any fractional share in accordance with Section
1.5(d)) and any dividends or other distributions to which such holder is
entitled in accordance with Section 1.8.

      1.10  TAX CONSEQUENCES. For federal income tax purposes, the Merger is
intended to constitute a reorganization within the meaning of Section 368 of the
Code. The parties to this Agreement hereby adopt this Agreement as a "plan of
reorganization" within the meaning of Sections 1.368-2(g) and 1.368-3(a) of the
United States Treasury Regulations.

      1.11  ACCOUNTING CONSEQUENCES. For accounting purposes, the Merger is
intended to be treated as a "pooling of interests."

      1.12  FURTHER ACTION.  If, at any time after the Effective Time, any
further action is determined by Parent to be necessary or desirable to carry out
the purposes of this Agreement or to vest the Surviving Corporation with full
right, title and possession of and to all rights and property of Merger Sub and
the Company, the officers and directors of the Surviving Corporation and Parent
shall be fully authorized (in the name of Merger Sub, in the name of the Company
and otherwise) to take such action.

attempt or threat to cancel, return or substantially reduce would have a
Material Adverse Effect on the Acquired Corporations.  The Company has not
experienced any pattern of material customer complaints concerning the Acquired
Corporations' products and/or services, nor have any of the Acquired

Corporations and (iii) any Contract to which an Acquired Corporation is a party
and pursuant to which an Acquired Corporation has licensed or transferred any
right (whether or not currently exercisable) to use, license or otherwise
exploit any Acquired Corporation Proprietary Asset to any Person. The Acquired

precautions to protect and maintain the confidentiality and secrecy of all
material Acquired Corporation Proprietary Assets (except Acquired Corporation
Proprietary Assets whose value would be unimpaired in any material respect by
disclosure).  Without limiting the generality of the foregoing, (i) all current
employees of the Acquired Corporations who are or were involved in, or who have
contributed to, the creation or development of any material Acquired Corporation
Proprietary Asset have executed and delivered to the Acquired Corporations an
agreement that at the time of execution was in the form of the Company's then

tradenames, service marks, maskwork rights, copyrights and trade secrets held by
any of the Acquired Corporations are valid, enforceable and subsisting; (ii)

and (iv) no other Person is infringing, misappropriating or making any unlawful
or unauthorized use of, and no Proprietary Asset owned or used by any other

          (e) The Acquired Corporation Proprietary Assets constitute all the
Proprietary Assets necessary to enable the Acquired Corporations to conduct
their business in the manner in which such business has been and is being
conducted.  Except as set forth in Part 2.10(e) of the company disclosure
Schedule, none of the Acquired Corporations has (i) licensed any of the Acquired
Corporation Proprietary Assets to any Person on an exclusive basis, (ii) entered

Corporation has disclosed or delivered to any Person, or permitted the
disclosure or delivery to any escrow agent or other Person, of the source code,
or any portion of the source code of any Acquired Corporation Proprietary Asset
(other than those Contracts entered into in the ordinary course of business on
terms that do not deviate in any material respect from the Company's Standard
Source Code Escrow Agreement).  No event has occurred, and no circumstance or
condition exists, that (with or without notice or lapse of time) will, or would
reasonably be expected to, result in the required disclosure or delivery by the
Acquired Corporations or any of their escrow agents to any Person of the source
code, or any portion or aspect of the source code, or any proprietary
information or algorithm contained in any source code, of any Acquired
Corporation Proprietary Asset.  Neither the execution of this Agreement nor the
consummation of any of the transactions contemplated hereby would

and (ii) respond to all date elements and date input so as to resolve any
ambiguity as to century in a disclosed, defined and pre-determined manner and
provide date information in ways which are unambiguous as to century, either by

of any amount that would not be deductible pursuant to Section 280G or Section

Revenue Service with respect to such Plan (if such Plan is intended to be
qualified under Section 401(a) of the Code).

          (e) None of the Acquired Corporations is or has ever been required to
be treated as a single employer with any other Person under Section 4001(b)(1)

ever made a complete or partial withdrawal from a multi-employer plan, as such
term is defined in Section 3(37) of ERISA, resulting in "withdrawal liability,"
as such term is defined in Section 4201 of ERISA (without regard to subsequent
reduction or waiver of such liability under either Section 4207 or 4208 of
ERISA).

          (f) None of the Acquired Corporations has any commitment to create any

the meaning of Section 4980B(g)(2) of the Code, the provisions of Section 4980B
of the Code ("COBRA") have been complied with in all material respects.

          (i) To the knowledge of the Company, each of the Plans has been
operated and administered in all material respects in accordance with applicable
Legal Requirements, including but not limited to ERISA and the Code.

          (j) Each of the Plans intended to be qualified under Section 401(a) of
the Code has received a favorable determination, opinion, advisory or
notification letter from the Internal Revenue Service or has an application
currently pending, and the Company is not aware of any material reason why any
such letter should be revoked.

          (k) Neither the execution, delivery or performance of this Agreement,
nor the consummation of the Merger or any of the other transactions contemplated
by this Agreement, will result in any payment (including any bonus, golden
parachute or severance payment) to any current or former employee or director of
any of the Acquired Corporations (whether or not under any Plan), or materially
increase the benefits payable under any Plan, or result in any 

                                      20.
<PAGE>
 
acceleration of the time of payment or vesting of any such benefits (unless the
Parent causes a partial or full termination to occur under a Pension Plan).

          (l) Part 2.16 of the Company Disclosure Schedule contains a list of
all salaried employees of each of the Acquired Corporations as of the date of
this Agreement, and correctly reflects, in all material respects, their base
salaries, their targeted annual bonus amounts, their dates of employment and
their positions.  None of the Acquired Corporations is a party to any collective
bargaining contract or other Contract with a labor union involving any of its
employees.  All of the employees of the Acquired Corporations are "at will"
employees.

          (m) Each Plan complies in all material respects with all applicable
Legal Requirements.  Each of the Acquired Corporations is in compliance in all
material respects with all Contracts relating to employment, employment
practices, wages, bonuses and terms and conditions of employment, including
employee compensation matters.

          (n) Each of the Plans in effect as of the Closing Date shall be
maintained in effect with respect to current employees, consultants, directors,
officers and other individuals who are covered by any such Plan immediately
prior to the Closing Date (the "AFFILIATED EMPLOYEES") until Parent otherwise
determines after the Closing Date; provided, however, that Parent or its
Subsidiary shall provide benefits to the Affiliated Employees for a period of
not less than one (1) year following the Closing Date which are no less
favorable in the aggregate than those provided under the Company's Pension Plans
and Welfare Plans. Without limitation of the foregoing, each employee of the
Company or Merger Sub immediately prior to the Closing Date who is participating
in any Plan shall receive credit for pre-Closing service with the Company and
its Subsidiaries or predecessor entities for all purposes under the Company's
Pension Plans and Welfare Plans or any successor plans to such plans offered by

eligibility to participate, vesting and waiting periods under any benefit plan
of Parent or any of its Subsidiaries or affiliates.

     2.17  ENVIRONMENTAL MATTERS.  Except as would not have a Material Adverse
Effect on the Acquired Corporations:  each of the Acquired Corporations is in
compliance in all material respects with all applicable Environmental Laws,
which compliance includes the possession by each of the Acquired Corporations of
all permits and other Governmental Authorizations required under applicable
Environmental Laws, and compliance with the terms and conditions thereof; none
of the Acquired Corporations has received any notice whether from a Governmental
Body, citizens group, employee or otherwise, that alleges that any of the
Acquired Corporations is not in compliance with any Environmental Law, and, to
the knowledge of the Company, there are no circumstances that will prevent or
interfere with the compliance by any of the Acquired Corporations with any
Environmental Law in the future; to the best of the knowledge of the Company, no
current or prior owner of any property leased or controlled by any of the
Acquired Corporations has received any written notice whether from a Government
Body, citizens group, employee or otherwise, that alleges that such current or
prior owner or any of the Acquired Corporations is not in compliance with any
Environmental Law; to the knowledge of the Company, all property that is leased
to, controlled by or used by the Company, and all surface water, groundwater and
soil associated with or adjacent to such property is in clean and healthful
condition and is free of any material illegal environmental contamination.  (For
purposes of this Section 2.17: (i) "ENVIRONMENTAL LAW" means any federal, state,
local or 

                                      21.

foreign Legal Requirement relating to pollution or protection of human health or
the environment (including ambient air, surface water, ground water, land

Corporations, none of the Acquired Corporations has received any written notice
regarding any actual or possible (a) cancellation or invalidation of any
insurance policy, (b) refusal of any coverage or rejection of any material claim
under any insurance policy, or (c) material adjustment in the amount of the
premiums payable with respect to any insurance policy.

     2.19  TRANSACTIONS WITH AFFILIATES. Except as set forth in the Company SEC
Documents, since the date of the Company's last proxy statement filed with the
SEC, no event has occurred as of the date of this Agreement that would be
required to be reported by the Company pursuant to Item 404 of Regulation S-K
promulgated by the SEC. Part 2.19 of the Company Disclosure Schedule identifies
each person who is an "affiliate" (as that term is used in Rule 145 promulgated
under the Securities Act) of the Company as of the date of this Agreement.

     2.20  LEGAL PROCEEDINGS; ORDERS.

           (a) As of the date hereof, except as set forth in Part 2.20 of the

of the assets owned or used by any of the Acquired Corporations, including,
without limitation, any Acquired Company Proprietary Asset; or (ii) that
challenges, or that may have the effect of preventing, delaying, making illegal
or otherwise interfering with, the Merger or any of the other transactions
contemplated by this Agreement.   As of the date hereof, to the knowledge of the
Company, no event has occurred, and no claim, dispute or other condition or
circumstance exists, that will, or that would reasonably be expected to, cause
or provide a bona fide basis for a director or executive officer of any of the
Acquired Corporations to seek indemnification from any of the Acquired
Corporations.

           (b) There is no order, writ, injunction, judgment or decree to which
any of the Acquired Corporations, or any of the assets material to the business
of the Acquired Corporations, is subject.  To the knowledge of the Company, no
officer or other employee of any of the Acquired Corporations is subject to any
order, writ, injunction, judgment or decree that 

                                      22.

conduct, activity or practice relating to the business of any of the Acquired
Corporations.

     2.21  AUTHORITY; INAPPLICABILITY OF ANTI-TAKEOVER STATUTES; BINDING NATURE

     2.22  NO EXISTING DISCUSSIONS.  As of the date of this Agreement, none of
the Acquired Corporations, and no Representative of any of the Acquired

     2.23  ACCOUNTING MATTERS.  To the knowledge of the Company, neither the
Company nor any of its affiliates has taken or agreed to, or plans to, take any
action that would prevent Parent from accounting for the Merger as a "pooling of
interests."

the shares of Company Common Stock outstanding on the record date for the
Company Shareholder Meeting (the "REQUIRED COMPANY SHAREHOLDER VOTE") is the

          (a) From the date of this Agreement until the earlier of the Effective
Time or termination of this Agreement pursuant to Section 8, the Company shall
not, and shall not authorize or permit any Subsidiary of the Company or any
Representative of any of the Acquired Corporations (including for purposes of
this Section 4.4(a) each of the affiliate shareholders of the Company listed on
Exhibit B-1) to, (i) solicit, initiate, encourage or induce the making,
submission or announcement of any Acquisition Proposal or take any action that

shall not prohibit the Company from furnishing nonpublic information regarding
the Acquired Corporations to, entering into a confidentiality agreement with or
entering into discussions with, any Person in response to a Superior Offer
submitted by such Person (and not withdrawn) if (1) neither the Company nor any
Representative of any of the Acquired Corporations shall have violated any of

to such Person by or on behalf of the Company, and (4) contemporaneously with
furnishing any such nonpublic information to such Person, the Company furnishes

has not been previously furnished by the Company to Parent). Without limiting
the generality of the foregoing, the Company acknowledges and agrees that any
violation of any of the restrictions set forth in the preceding sentence by any
Representative of any of the Acquired Corporations, whether or not such
Representative is purporting to act on behalf of any of the Acquired
Corporations, shall be deemed to constitute a breach of this Section 4.4 by the
Company.  In addition to the foregoing, the Company shall (i) provide Parent
with at least 24 hours prior notice (or such lesser prior notice as provided to

Offer (pursuant to Section 4.4(b) below).

          (b) The Company shall promptly notify Parent of any Acquisition
Proposal (including the identity of the Person making or submitting such

by any Person during the Pre-Closing Period.  The Company shall keep Parent
informed with respect to the status of any such Acquisition Proposal and any
material modification thereto.

          (c) The Company shall immediately cease and cause to be terminated any
existing discussions with any Person that relate to any Acquisition Proposal.

Agreement shall prohibit the Company from (i) taking and disclosing to its
shareholders a position contemplated by Rules 14d-9 and 14e-2(a) promulgated
under the Exchange Act or (ii) making any disclosure to the Company's
shareholders if, in the good faith judgment of the majority of the members of
the Board of Directors of the Company, after consultation with independent legal
counsel, failure to so disclose would be inconsistent with applicable laws.

efforts to cause its independent auditors to deliver to Parent on or prior to

other government officials, on the other hand, with respect to the S-4
Registration Statement, the Prospectus/Proxy Statement, any Other Filings or the

promptly inform Parent thereof and shall cooperate with Parent in filing such
amendment or supplement with the SEC and, if appropriate, in mailing such
amendment or supplement to the shareholders of the Company and the stockholders
of Parent.

          (b) Prior to the Effective Time, Parent shall use reasonable efforts
to obtain all regulatory approvals needed to ensure that the Parent Common Stock

the shareholders entitled to notice of and to vote at the Company Shareholders'
Meeting; provided, however, that Parent shall not be required (i) to qualify to
do business as a foreign corporation in any jurisdiction in which it is not now

approval of the Merger.  The Company Shareholders' Meeting will be held as
promptly as practicable and in any event, if permitted under applicable law,

this Agreement or, if as of the time for which Company Shareholders' Meeting is
originally scheduled (as set forth in the Prospectus/Proxy Statement) there are
insufficient shares of Company Common Stock represented (either in person or by
proxy) to constitute a quorum necessary to conduct the business of the Company's
Shareholders' Meeting.  The Company shall ensure that the Company Shareholders'
Meeting is called, noticed, 

                                      36.
<PAGE>
 
convened, held and conducted, and subject to Section 5.2(c) that all proxies
solicited by the Company in connection with the Company Shareholders' Meeting
are solicited, in compliance with all applicable Legal Requirements. The
Company's obligation to call, give notice of, convene and hold the Company
Shareholders' Meeting in accordance with this Section 5.2(a) shall not be
limited or otherwise affected by the commencement, disclosure, announcement or
submission to the Company of any Acquisition Proposal, or by any withdrawal,
amendment or modification of the recommendation of the Board of Directors of the
Company with respect to the Merger.

          (b) Subject to Section 5.2(c):  (i) the Board of Directors of the

recommendation of the Board of Directors of the Company that the Company's

Merger.  For purposes of this Agreement, said recommendation of the Board of
Directors shall be deemed to have been modified in a manner adverse to Parent if
said recommendation shall no longer be unanimous.

          (c) Nothing in this Agreement shall prevent the Board of Directors of
the Company from withholding, withdrawing, amending or modifying its unanimous
recommendation in favor of the Merger if (i) a Superior Offer is made to the
Company and is not withdrawn, (ii) neither the Company nor any of its
Representatives shall have violated any of the restrictions set forth in Section
4.4, and (iii) the Board of Directors of the Company concludes in good faith,
after consultation with its outside counsel, that, in light of such Superior
Offer, the withholding, withdrawal, amendment or modification of such
recommendation is required in order for the Board of Directors of the Company to
comply with its fiduciary obligations to the Company's shareholders under
applicable law (and, in any such case, to the extent it does so, the Company may
refrain from soliciting proxies to secure the vote of its shareholders as may
otherwise be required hereby).  Subject to applicable laws, nothing contained in
this Section 5.2 shall limit the Company's obligation to hold and convene the

practicable and in any event, if permitted under applicable law, within forty-
five (45) days after the S-4 Registration Statement is declared effective under

<PAGE>
 
Agreement, Parent may adjourn or postpone the Parent Stockholders' Meeting to
the extent necessary to ensure that any necessary supplement or amendment to the
Prospectus/Proxy Statement is provided to Parent's stockholders in advance of a

          (a) At the Effective Time, all rights with respect to Company Common
Stock under each Company Option then outstanding shall be converted into and
become rights with respect to Parent Common Stock, and Parent shall assume each
such Company Option in accordance with the terms (as in effect as of the date of
this Agreement) of the stock option plan under which it was issued and the stock
option agreement by which it is evidenced.  From and after the Effective Time,
(i) each Company Option assumed by Parent may be exercised solely for shares of
Parent Common Stock, (ii) the number of shares of Parent Common Stock subject to
each such Company Option shall be equal to the number of shares of Company
Common Stock subject to such Company Option immediately prior to the Effective
Time multiplied by the Exchange Ratio, rounding down to the nearest whole share
(with cash, less the applicable exercise price, being payable for any fraction
of a share), (iii) the per share exercise price under each such Company Option
shall be adjusted by dividing the per share exercise price under such Company
Option by the Exchange Ratio and rounding up to the nearest cent and (iv) any

Section 5.5(a) shall, in accordance with its terms, be subject to further
adjustment as appropriate to reflect any stock split, stock dividend, reverse
stock split, reclassification, recapitalization or other similar transaction
subsequent to the Effective Time.  It is the intention of the parties that
Company Options assumed by Purchaser qualify following the Effective Time as
incentive stock options as defined in Section 422 of the Code to the extent such
Company Options qualified as incentive stock options immediately prior to the
Effective Date.

          (b) The Company shall take all action that, subject to pooling
restrictions, may be necessary (under the plans pursuant to which Company
Options are outstanding and otherwise) to effectuate the provisions of this
Section 5.5 and to ensure that, from and after the Effective Time, holders of
Company Options have no rights with respect thereto other than those
specifically provided in this Section 5.5.

          (c) Promptly following the Effective Date, Parent will issue to each
holder of an assumed or replaced Company Option a document evidencing the

treatment of the Purchase Plan.

     5.7  INDEMNIFICATION OF OFFICERS AND DIRECTORS.

          (a) All rights to indemnification existing in favor of the directors
and officers of the Company for acts and omissions occurring prior to the
Effective Time, as provided in the Company's Articles of Incorporation or Bylaws
(as in effect as of the date of this Agreement) and as provided in any
indemnification agreements between the Company and said officers and directors
(as in effect at the Effective Time), shall survive the Merger and shall be the
obligation of and observed by Parent and the Surviving Corporation for a period
of not less than eight (8) years from and after the Effective Time.

which the Merger becomes effective, the Surviving Corporation shall maintain in
effect, for the benefit of the current directors and officers of the Company
with respect to acts or omissions occurring prior to the Effective Time, the
existing policy of directors' and officers' liability insurance maintained by
the Company as of the date of this Agreement (the "EXISTING POLICY"); provided,
however, that (i) the Surviving Corporation may substitute for the Existing
Policy a policy or policies of comparable coverage, and (ii) the Surviving
Corporation shall not be required to pay an annual premium for the Existing
Policy (or for any substitute policies) in excess of 150% of the amount of the
last annual premium paid by the Company prior to the date of this Agreement for
the Existing Policy (the "PAST PREMIUM AMOUNT").  In the event any future annual
premium for the Existing Policy (or any substitute policies) exceeds 150% of the
Past Premium Amount, the Surviving Corporation shall be entitled to reduce the
amount of coverage of the Existing Policy (or any substitute policies) to the
amount of coverage that can be obtained for a premium equal to 150% of the Past
Premium Amount.

          (c) This Section 5.7 shall survive the consummation of the Merger at
the Effective Time, is intended to be for the benefit of, and enforceable by,
each person entitled to indemnification pursuant hereto and each such person's
or entity's heirs and representatives, and shall be binding on all successors
and assigns of Parent and the Surviving Corporation.

     5.8  POOLING OF INTERESTS; TAX FREE REORGANIZATION.  Each of the Company
and Parent agrees (a) not to take any action during the Pre-Closing Period that
would adversely affect the ability of Parent to account for the Merger as a
"pooling of interests," (b) to use all reasonable efforts to attempt to ensure
that none of its "affiliates" (as that term is used in Rule 145 promulgated
under the Securities Act) takes any action that could adversely affect the
ability of Parent to account for the Merger as a "pooling of interests" and (c)
not to take any action either prior to or after the Effective Time that would
reasonably be expected to cause the Merger to fail to qualify as a
"reorganization" under Section 368(a) of the Code.  The Company and Parent each
agrees to provide Coopers & Lybrand L.L.P. and KPMG Peat Marwick L.L.P. such
letters as may be reasonably requested by either of them with respect to the
letters referred to in Sections 6.5(e) and 6.5(f) or any other letters relating

supersede all prior agreements and understandings between the parties with
respect thereto.

     6.7  ASSIGNMENT; BINDING EFFECT.  Except as provided herein, neither this
Agreement nor any of the interests or obligations hereunder may be assigned or
delegated by Shareholder and any attempted or purported assignment or delegation
of any of such interests or obligations shall be void.  Subject to the preceding
sentence, this Agreement shall be binding upon Shareholder and his heirs,

enforceability of any other provision of this Agreement.  Each provision of this
Agreement is separable from every other provision of this Agreement, and each
part of each provision of this Agreement is separable from every other part of
such provision.

     5.6  ENTIRE AGREEMENT.  This Agreement, the Proxy, and any other documents
delivered by the parties in connection herewith constitute the entire agreement
between the parties with respect to the subject matter hereof and thereof and
supersede all prior agreements and understandings between the parties with
respect thereto.

     5.7  ASSIGNMENT; BINDING EFFECT.  Except as provided herein, neither this
Agreement nor any of the interests or obligations hereunder may be assigned or
delegated by Shareholder and any attempted or purported assignment or delegation
of any of such interests or obligations shall be void.  Subject to the preceding
sentence, this Agreement shall be binding upon Shareholder and his heirs,
estate, executors, personal representatives, successors and assigns, and shall
inure to the benefit of Company and its successors and assigns.  This Agreement
shall be binding upon any Person to whom any Subject Securities are transferred

hereof. Nothing in this Agreement is intended to confer on any Person (other
than Company and its successors and assigns) any rights or remedies of any
nature.

     5.8  SPECIFIC PERFORMANCE.  The parties agree that irreparable damage would
occur in the event that any of the provisions of this Agreement or the Proxy was
not performed in accordance with its specific terms or was otherwise breached.
Shareholder agrees that, in the event of any breach or threatened breach by
Shareholder of any covenant or obligation contained in this Agreement or in the
Proxy, Company shall be entitled (in addition to any other remedy that may be

Affiliate Agreement shall limit any of Shareholder's obligations, or any of the
rights or remedies of Company, under this Agreement.

     5.10  GOVERNING LAW.  This Agreement and the Proxy shall be construed in
accordance with, and governed in all respects by, the laws of the State of
California (without giving effect to principles of conflicts of laws).

separate counterparts, each of which when so executed and delivered shall be an
original, but all such counterparts shall together constitute one and the same
instrument.

Agreement and shall not be referred to in connection with the construction or

relating to this Agreement or the enforcement of any provision of this Agreement
is brought against Shareholder, the prevailing party shall be entitled to

other relief to which the prevailing party may be entitled).

     5.14  WAIVER.  No failure on the part of Company to exercise any power,
right, privilege or remedy under this Agreement, and no delay on the part of
Company in exercising any power, right, privilege or remedy under this
Agreement, shall operate as a waiver of such power, right, privilege or remedy;
and no single or partial exercise of any such power, right, privilege or remedy
shall preclude any other or further exercise thereof or of any other power,
right, privilege or remedy. Company shall not be deemed to have waived any claim
available to Company arising out of this Agreement, or any power, right,
privilege or remedy of Company under this Agreement, unless the waiver of such
claim, power, right, privilege or remedy is expressly set forth in a written
instrument duly executed and delivered on behalf of Company;

                          COMPANY AFFILIATE AGREEMENT

     THIS AFFILIATE AGREEMENT (this "AGREEMENT") is dated as of ______________,
1998, by and between SIEBEL SYSTEMS, INC., a Delaware corporation ("PARENT"),
SCOPUS TECHNOLOGY, INC., a California corporation ("COMPANY"), and
("AFFILIATE").

     WHEREAS, Affiliate is a shareholder [and an officer and director] of the
Company.

     WHEREAS, Parent, Syracuse Acquisition Sub, Inc., a California corporation
and a wholly-owned subsidiary of Parent ("MERGER SUB"), and the Company have
entered into an Agreement and Plan of Merger and Reorganization dated as of
March 1, 1998 (the "MERGER AGREEMENT"), providing for the merger of Merger Sub
with and into the Company (the "MERGER").  The Merger Agreement contemplates
that, upon consummation of the Merger, (i) the holders of the common stock of
the Company ("COMPANY COMMON STOCK") will receive shares of common stock of
Parent ("PARENT COMMON STOCK") in exchange for their shares of Company Common
Stock and (ii) the Company will become a wholly-owned subsidiary of Parent.  It
is accordingly contemplated that Affiliate will receive shares of Parent Common
Stock in the Merger.

     WHEREAS, Affiliate understands that the Parent Common Stock being issued in
the Merger will be issued pursuant to a registration statement on Form S-4 and
that Affiliate may be deemed to be an "affiliate" of the Company, as the term
"affiliate" is used (i)for purposes of paragraphs (c) and (d) of Rule 145 ("RULE
145") of the General Rules and Regulations of the Securities and Exchange
Commission (the "SEC") under the Securities Act of 1933, as amended (the
"SECURITIES ACT"), and (ii) in the SEC's Accounting Series Releases 130 and 135,
and, as such, Affiliate may only transfer, sell or dispose of such Parent Common
Stock in accordance with this Affiliate Agreement and Rule 145.

     WHEREAS, it is a condition to the consummation of the Merger pursuant to
the Merger Agreement that the independent accounting firms that audit the annual
financial statements of Parent and the Company will have delivered the written
concurrences with the conclusions of management of Parent and the Company to the
effect that the Merger will be accounted for as a pooling of interests under
Accounting Principles Board Opinion No. 16.

     NOW, THEREFORE, in order to induce Parent to consummate the transactions
contemplated by the Merger Agreement, and for other valuable consideration (the
receipt and sufficiency of which are hereby acknowledged by Affiliate),
Affiliate hereby covenants and agrees as follows:

     SECTION 1.  REPRESENTATIONS AND WARRANTIES.  Affiliate represents and
warrants to Parent as follows:

                                       1.
<PAGE>
 
          (a) Affiliate is the holder and "beneficial owner" (as defined in Rule
13d-3 under the Securities Exchange Act of 1934, as amended) of the number of
shares of the Company Common Stock set forth under Affiliate's signature below
(the "COMPANY SHARES"), and Affiliate has good and valid title to the Company
Shares, free and clear of any liens, pledges, security interests, adverse
claims, equities, options, proxies, charges, encumbrances or restrictions of any
nature with the exception of any option to purchase shares of Company Common
Stock owned by Affiliate that is held by General Atlantic Partners 17, L.P. or
GAP Coinvestments Partners, L.P. as of the date of this Agreement.

          (b) Affiliate has carefully read this Agreement, and has discussed
with Affiliate's own independent counsel to the extent Affiliate felt necessary
the limitations imposed on Affiliate's ability to sell, transfer or otherwise
dispose of the shares of Parent Common Stock that Affiliate is to receive in the
Merger (the "PARENT SHARES").  Affiliate fully understands the limitations this
Agreement places upon Affiliate's ability to sell, transfer or otherwise dispose
of the Parent Shares.

          (c) Affiliate understands that the representations, warranties and
covenants set forth herein will be relied upon by Parent, the Company, and their
respective affiliates, counsel and accounting firms for purposes of determining
Parent's eligibility to account for the Merger as a "pooling of interests," and
that substantial losses and damages may be incurred by these persons if
Affiliate's representations, warranties or covenants are breached.

     SECTION 2.  PROHIBITION AGAINST TRANSFER.  In addition to the restrictions
set forth elsewhere herein, Affiliate agrees that Affiliate shall not effect any
sale, transfer or other disposition of the Parent Shares unless:

          (a) such sale, transfer or other disposition is made in conformity
with the volume and other requirements of Rule 145 under the Securities Act, as
evidenced by a broker's letter and a representation letter executed by Affiliate
(reasonably satisfactory in form and content to Parent), each stating that such
requirements have been met;

          (b) counsel reasonably satisfactory to Parent shall have advised
Parent in a written opinion letter (reasonably satisfactory in form and content
to Parent), upon which Parent may rely, that such sale, transfer or other
disposition will be exempt from registration under the Securities Act;

          (c) such sale, transfer or other disposition is effected pursuant to
an effective registration statement under the Securities Act; or

          (d) an authorized representative of the SEC shall have rendered
written advice to Affiliate to the effect that the SEC would take no action, or
that the staff of the SEC would not recommend that the SEC take action, with
respect to such proposed sale, transfer or other disposition, and a copy of such
written advice and all other related communications with the SEC shall have been
delivered to Parent.

                                       2.
<PAGE>
 
     SECTION 3.  STOP TRANSFER INSTRUCTIONS; LEGEND.  Affiliate acknowledges and
agrees that (a) stop transfer instructions will be given to Parent's transfer
agent with respect to the Parent Shares, and (b) each certificate representing
any of such shares of Parent Common Stock or any substitutions thereof shall
bear a legend (together with any other legend or legends required by applicable
state securities laws or otherwise), stating in substance:

          THE SHARES REPRESENTED BY THIS CERTIFICATE WERE ISSUED IN A
          TRANSACTION TO WHICH RULE 145 PROMULGATED UNDER THE SECURITIES ACT OF
          1933 APPLIES.  THE SHARES REPRESENTED BY THIS CERTIFICATE MAY NOT BE
          OFFERED, SOLD OR OTHERWISE TRANSFERRED, ASSIGNED, PLEDGED OR
          HYPOTHECATED EXCEPT IN ACCORDANCE WITH THE PROVISIONS OF SUCH RULE AND
          IN ACCORDANCE WITH THE TERMS OF AN AGREEMENT DATED AS OF _______,
          1998, BETWEEN THE REGISTERED HOLDER HEREOF AND SIEBEL SYSTEMS, INC., A
          COPY OF WHICH AGREEMENT IS ON FILE AT THE PRINCIPAL OFFICES OF SIEBEL
          SYSTEMS, INC..

     SECTION 4.  COVENANTS RELATED TO POOLING OF INTERESTS.  In accordance with
SEC Staff Accounting Bulletin No. 65 ("SAB 65"), during the period contemplated
by SAB 65, until the earlier of (i) Parent's public announcement of financial
results covering at least 30 days of combined operations of Parent and the
Company or (ii) the Merger Agreement is terminated in accordance with its terms,
Affiliate will not sell, exchange, transfer, pledge, distribute, or otherwise
dispose of or grant any option, establish any "short" or put-equivalent position
with respect to or enter into any similar transaction (through derivatives or
otherwise) intended or having the effect, directly or indirectly, to reduce its
risk relative to:  (i) any shares of Company Common Stock, except pursuant to
and upon the consummation of the Merger; or (ii) any shares of Parent Common
Stock received by Affiliate in the Merger or any shares of Parent Common Stock
received by Affiliate upon exercise of options assumed by Parent in connection
with the Merger.  Parent may, at its discretion, cause a restrictive legend
covering the restrictions referred to in this Section 4 to be placed on Parent
Common Stock certificates issued to Affiliate in the Merger and place a stock
transfer notice consistent with the restrictions referred to in this Section 4
with its transfer agent with respect to such certificates, provided such
restrictive legend shall be removed and/or notice shall be countermanded
promptly upon expiration of the necessity therefor at the request of Affiliate.

     SECTION 5.  PERMITTED TRANSFERS.  Notwithstanding anything to the contrary
contained in this Agreement, Affiliate (i) may transfer Affiliate's pro rata
portion (of the total number of shares available under the "de minimis"
exception referred to in this clause (i) to all affiliates of Parent and
Company) of the "de minimis" number of shares of Company Common Stock and Parent
Common Stock available for sale in accordance with SEC Staff Accounting Bulletin
No. 76 (the "DE MINIMIS POOL") contingent upon confirmation and approval by
legal counsel for Company and independent auditors to the Company and Parent
that such transfer qualifies as within Affiliate's pro rata portion of the De
Minimis Pool and does not otherwise adversely affect the Parent's ability to
account for the Merger as a "pooling of interests" (ii) may (with the written
consent of Parent, not to be unreasonably withheld): (A) transfer shares of
Company Common Stock or Parent Common Stock to the Company in payment of the
exercise

                                       3.
<PAGE>
 
price of options to purchase Company Common Stock; (B) transfer shares of Parent
Common Stock in payment of the exercise price of options to purchase Parent
Common Stock; (C) transfer shares of Company Common Stock or Parent Common Stock
to any organization qualified under Section 501(c)(3) of the Internal Revenue
Code of 1986, as amended, so long as such organization has traditionally been
supported by contributions from the general public (as opposed to being
supported largely by a specific donor); and (D) transfer shares of Company
Common Stock or shares of Parent Common Stock to a trust established for the
benefit of Affiliate and/or for the benefit of one or more members of
Affiliate's family, or make a bona fide gift of shares of Common Stock of the
Company or shares of Parent Common Stock to one or more members of Affiliate's
family, provided that in the case of a transfer or gift pursuant to this clause
(C) or (D), a transferee of such shares agrees to be bound by the limitations
set forth in this Agreement.

     SECTION 6.  SPECIFIC PERFORMANCE. The parties agree that irreparable damage
would occur in the event that any of the provisions of this Agreement was not
performed in accordance with its specific terms or was otherwise breached.
Affiliate agrees that, in the event of any breach or threatened breach by
Affiliate of any covenant or obligation contained in this Agreement, each of
Parent and the Company shall be entitled (in addition to any other remedy that
may be available to it, including monetary damages) to seek and obtain (a) a
decree or order of specific performance to enforce the observance and
performance of such covenant or obligation, and (b) an injunction restraining
such breach or threatened breach.

     SECTION 7.  INDEPENDENCE OF OBLIGATIONS.  The covenants and obligations of
Affiliate set forth in this Affiliate Agreement shall be construed as
independent of any other agreement or arrangement  between Affiliate, on the one
hand, and the Company or Parent, on the other. The existence of any claim or
cause of action by Affiliate against the Company or Parent  shall not constitute
a defense to the enforcement of any of such covenants or obligations against
Affiliate.

     SECTION 8.  NOTICES.  Any notice or other communication required or
permitted to be delivered under this Agreement shall be in writing and shall be
deemed properly delivered, given and received when delivered (by hand, by
registered mail, by courier or express delivery service or by facsimile
confirmation) to the address or facsimile telephone number set forth beneath the
name of such party below (or to such other address or facsimile telephone number
as such party shall have specified in a written notice given to the other

                          PARENT AFFILIATE AGREEMENT

     THIS AFFILIATE AGREEMENT (this "AGREEMENT") is dated as of March 1, 1998,
by and between SIEBEL SYSTEMS, INC., a Delaware corporation ("PARENT"), SCOPUS
TECHNOLOGY, INC., a California corporation ("Company") and ___________________
("AFFILIATE").

     WHEREAS, Affiliate is a shareholder and an officer and director of Parent.

     WHEREAS, Parent, Syracuse Acquisition Sub, Inc., a California corporation
and a wholly-owned subsidiary of Parent ("MERGER SUB"), and Company have entered
into an Agreement and Plan of Merger and Reorganization dated as of March 1,
1998 (the "MERGER AGREEMENT"), providing for the merger of Merger Sub with and
into the Company (the "MERGER").  The Merger Agreement contemplates that, upon
consummation of the Merger, (i) the holders of the common stock of the Company
("COMPANY COMMON STOCK") will receive shares of common stock of Parent ("PARENT
COMMON STOCK") in exchange for their shares of Company Common Stock and (ii) the
Company will become a wholly-owned subsidiary of Parent.

     WHEREAS, it is a condition to the consummation of the Merger pursuant to
the Merger Agreement that the independent accounting firms that audit the annual
financial statements of Parent and the Company will have delivered the written
concurrences with the conclusions of management of Parent and the Company to the
effect that the Merger will be accounted for as a pooling of interests under
Accounting Principles Board Opinion No. 16.

     NOW, THEREFORE, intending to be legally bound, in order to induce the
Company and Parent to consummate the transactions contemplated by the Merger
Agreement, and for other valuable consideration, the receipt and sufficiently of
which are hereby acknowledged by Affiliate, Affiliate hereby covenants and
agrees as follows:

     SECTION 1.  REPRESENTATIONS AND WARRANTIES.  Affiliate represents and
warrants to Parent as follows:

          (a) Affiliate is the holder and "beneficial owner" (as defined in Rule
13d-3 under the Securities Exchange Act of 1934, as amended) of the number of
shares of the Parent Common Stock set forth under Affiliate's signature below
(the "PARENT SHARES"), and Affiliate has good and valid title to the Parent
Shares, free and clear of any liens, pledges, security interests, adverse
claims, equities, options, proxies, charges, encumbrances or restrictions of any
nature.

          (b) Affiliate has carefully read this Agreement, and has discussed
with Affiliate's own independent counsel to the extent Affiliate felt necessary
the limitations imposed on Affiliate's ability to sell, transfer or otherwise
dispose of the shares of Parent Common Stock. Affiliate fully understands the
limitations this Agreement places upon Affiliate's ability to sell, transfer or
otherwise dispose of the Parent Shares.

                                       1.
<PAGE>
 
          (c) Affiliate understands that the representations, warranties and
covenants set forth herein will be relied upon by Parent, the Company, and their
respective affiliates, counsel and accounting firms for purposes of determining
Parent's eligibility to account for the Merger as a "pooling of interests," and
that substantial losses and damages may be incurred by these persons if
Affiliate's representations, warranties or covenants are breached.

     SECTION 2.  COVENANTS RELATED TO POOLING OF INTERESTS.  In accordance with
SEC Staff Accounting Bulletin No. 65 ("SAB 65"), during the period contemplated
by SAB 65, until the earlier of (i) Parent's public announcement of financial
results covering at least 30 days of combined operations of Parent and the
Company or (ii) the Merger Agreement is terminated in accordance with its terms,
Affiliate will not sell, exchange, transfer, pledge, distribute or otherwise
dispose of or grant any option, establish any "short" or put-equivalent position
with respect to or enter into any similar transaction (through derivatives or
otherwise) intended or having the effect, directly or indirectly, to reduce its
risk relative to any Parent Common Stock.  Parent may, at its discretion, place
a stock transfer notice consistent with the restrictions referred to in this
Section 2 with its transfer agent with respect to such certificates, provided
such restrictive legend shall be removed and/or notice shall be countermanded
promptly upon expiration of the necessity therefor at the request of Affiliate.

     SECTION 3.  PERMITTED TRANSFERS.  Notwithstanding anything to the contrary
contained in this Agreement, Affiliate may (i) transfer Affiliate's pro rata
portion (of the total number of shares available under the "de minimis"
exception referred to in this clause (i) to all affiliates of Parent and
Company) of the "de minimis" amount of Company Common Stock and Parent Common
Stock available for sale in accordance with SEC Staff Accounting Bulletin No. 76
(the "DE MINIMIS POOL") contingent upon confirmation by legal counsel for Parent
and independent auditors for Parent and the Company as to whether such transfer
qualifies as within Affiliate's pro rata portion of the De Minimis Pool and (ii)
may (with the written consent of Parent, not to be unreasonably withheld): (A)
transfer shares of Parent Common Stock in payment of the exercise price of
options to purchase Parent Common Stock; (B) transfer shares of Parent Common
Stock to any organization qualified under Section 501(c)(3) of the Internal
Revenue Code of 1986, as amended, so long as such organization has traditionally
been supported by contributions from the general public (as opposed to being
supported largely by a specific donor); and (C) transfer shares of Parent Common
Stock to a trust established for the benefit of Affiliate and/or for the benefit
of one or more members of Affiliate's family, or make a bona fide gift of Parent
Common Stock to one or more members of Affiliate's family, provided that in the
case of a transfer or gift pursuant to this clause (B) or (C), a transferee of
such shares agrees to be bound by the limitations set forth in this Agreement.

     SECTION 4.  SPECIFIC PERFORMANCE. The parties agree that irreparable damage
would occur in the event that any of the provisions of this Agreement was not
performed in accordance with its specific terms or was otherwise breached.
Affiliate agrees that, in the event of any breach or threatened breach by
Affiliate of any covenant or obligation contained in this Agreement, each of
Parent and the Company shall be entitled (in addition to any other remedy that
may be available to it, including monetary damages) to seek and obtain (a) a
decree or order of specific performance to enforce the observance and
performance of such covenant or obligation, and (b) an injunction restraining
such breach or threatened breach.

                                       2.
<PAGE>
 
     SECTION 5.  INDEPENDENCE OF OBLIGATIONS.  The covenants and obligations of
Affiliate set forth in this Affiliate Agreement shall be construed as
independent of any other agreement or arrangement  between Affiliate, on the one
hand, and Parent or the Company , on the other. The existence of any claim or
cause of action by Affiliate against Parent or the Company shall not constitute
a defense to the enforcement of any of such covenants or obligations against
Affiliate.

     SECTION 6.  NOTICES.  Any notice or other communication required or
permitted to be delivered under this Agreement shall be in writing and shall be
deemed properly delivered, given and received when delivered (by hand, by
registered mail, by courier or express delivery service or by facsimile
confirmation) to the address or facsimile telephone number set forth beneath the

as such party shall have specified in a written notice given to the other

                            STOCK OPTION AGREEMENT
                                        
     STOCK OPTION AGREEMENT, dated as of March __, 1998 (this "Agreement"), by
and between SCOPUS TECHNOLOGY, INC., a California corporation (the "Company"),
and SIEBEL SYSTEMS, INC., a Delaware corporation ("Parent").

                                   RECITALS

     A.  The Company, Parent and Syracuse Acquisition Sub, a California
corporation ("Merger Sub"), are entering into an Agreement and Plan of
Reorganization, dated as of the date hereof (the "Merger Agreement"), providing
for, among other things, the merger of Merger Sub with and into the Company as
the surviving corporation in the Merger.

     B.  As a condition and inducement to Parent's willingness to enter into the
Merger Agreement, Parent has requested that the Company agree, and the Company
has agreed, to grant Parent the Option.

     C.  Terms not defined herein shall have the meanings set forth in the
Merger Agreement.

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

     1.  Grant of Option.  Subject to the terms and conditions set forth herein,
         ---------------
the Company hereby grants to Parent an irrevocable option (the "Option") to
purchase up to 3,493,879 shares of the common stock of the Company (such shares,
subject to adjustment under Section 4 below, being referred to as the "Option
Shares"), at a purchase price of $20.00 (subject to adjustment as set forth
under Section 4 below) per Option Share (the "Purchase Price").

     2.  Exercise of Option.
         ------------------

     (a) The Option shall become exercisable, and Parent may exercise the
Option, in whole or in part, on any one occasion at any time following the
occurrence of a Triggering Event; provided, however, that if the Option shall
have become exercisable under this Section 2(a), then the Option shall terminate
and be of no further force and effect upon the earliest to occur of (i) the
Effective Time, (ii) 270 days after the first occurrence of a Triggering Event,
and (iii) the valid termination of the Merger Agreement in accordance with its
terms prior to the occurrence of a Triggering Event.

     (b) If (i) the Company Shareholders' Meeting shall have been held (either
on the date for which such meeting was originally scheduled or pursuant to any
permissible adjournment or postponement) and the Merger Agreement and the Merger
shall not have been adopted and approved at such meeting by the Required Company
Shareholder Vote, (ii) following the date hereof and at or prior to the time of
the Company Shareholders' Meeting, an Acquisition Proposal shall have been
publicly announced, and (iii) on or prior to the first anniversary of the
termination of the Merger Agreement, the Company shall have entered into a
definitive agreement providing for a Company Acquisition or a Company
Acquisition shall have been consummated, then the Option shall become
exercisable, and Parent may exercise the Option, in whole or in part, on any one
occasion at any time following the date of such definitive agreement (or if
there is no definitive agreement, the consummation of such Company Acquisition);

                                       1
<PAGE>
 
provided, however, that if the Option shall have become exercisable under this
Section 2(b), then the Option shall terminate and be of no further force and
effect 180 days after the date of such definitive agreement (or if there is no
definitive agreement, 180 days after the consummation of such Company
Acquisition).

     (c)  Notwithstanding the termination of the Option, Parent shall be
entitled to purchase the Option Shares if it has exercised the Option in
accordance with the terms hereof prior to the termination of the Option, and the
termination of the Option shall not affect any rights hereunder which do not by
their terms terminate or expire prior to or as of such termination.

     (d) In the event that Parent wishes to exercise the Option, it shall send
to the Company a written notice (the date of which being herein referred to as
the "Notice Date") to that effect which notice also specifies a date not earlier
than three business days nor later than 20 business days from the Notice Date
for the closing of the purchase of the Option Shares to be purchased (the
"Option Closing Date"); provided, however, that (i) if the closing of the
purchase of such Option Shares pursuant to the Option (the "Option Closing")
cannot be consummated by reason of any applicable judgment, decree, order, law
or regulation, the period of time that otherwise would run pursuant to this
sentence shall run instead from the date on which such restriction on
consummation has expired or been terminated and (ii) without limiting the
foregoing, if prior notification to or approval of any regulatory authority is
required in connection with such purchase, Parent and the Company shall promptly
file the required notice or application for approval and shall cooperate in the
expeditious filing of such notice or application, and the period of time that
otherwise would run pursuant to this sentence shall run instead from the date on
which, as the case may be, (A) any required notification period has expired or
been terminated or (B) any required approval has been obtained, and in either
event, any requisite waiting period has expired or been terminated. The place of
the Option Closing shall be at the offices of Cooley Godward LLP, Five Palo Alto
Square, Palo Alto, California 94306, and the time of the Option Closing shall be
10:00 a.m. (West Coast Time) on the Option Closing Date (as it may be extended
pursuant to this Section 2(d)).

     3.  Payment and Delivery of Certificates.
         ------------------------------------

     (a) At the Option Closing, Parent shall pay to the Company in immediately
available funds by wire transfer to a bank account designated in writing by the
Company an amount equal to the Purchase Price multiplied by the number of Option
Shares being acquired by Parent.

     (b) At the Option Closing, simultaneously with the delivery of immediately
available funds as provided in Section 3(a), the Company shall deliver to Parent
a certificate or certificates representing the Option Shares to be purchased at
the Option Closing, which Option Shares shall be free and clear of all liens,
claims, charges and encumbrances of any kind whatsoever other than those created
by Parent or created under applicable securities laws.

     (c) Certificates for the Option Shares delivered at the Option Closing
shall have typed or printed thereon a restrictive legend which shall read
substantially as follows:

        "THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND MAY BE

                                       2
<PAGE>
 
REOFFERED OR SOLD ONLY IF SO REGISTERED OR IF AN EXEMPTION FROM SUCH
REGISTRATION IS AVAILABLE. THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE
ALSO SUBJECT TO BUY-BACK PROVISIONS IN FAVOR OF THE ISSUER."

It is understood and agreed that the foregoing legend with respect to securities
laws shall be removed by delivery of substitute certificate(s) without such
legend upon the sale of any Option Shares pursuant to (i) a registered public
offering or (ii) Rule 144 under the Securities Act or any other sale as a result
of which such legend is no longer required (upon the receipt by the Company of
an opinion of counsel reasonably satisfactory to the Company that the conditions
for removal of such legend have been satisfied).

     4.  Adjustment upon Changes in Capitalization, Etc.
         ----------------------------------------------
        
     (a) In the event of any stock dividend or extraordinary cash or other
distribution, split-up, merger, consolidation, recapitalization, combination,
sale of all or substantially all of the Company's assets, exchange of shares, or
similar transaction involving the Company or any Company Stock, the type and
number of shares or securities subject to the Option, and the Purchase Price
therefor, shall be adjusted appropriately, and proper provision shall be made in
the agreements governing such transaction, so that Parent shall receive upon
exercise of the Option the number and class of shares or other securities or
property that Parent would have received in respect of Company Stock if the
Option had been exercised immediately prior to such event or the record date
therefor, as applicable.

     (b) If at any time from the date the Option becomes exercisable through the
tenth anniversary of such date, Parent or any of Parent's affiliates effects a
sale, transfer or other disposition of the Option or any of the Option Shares or
any rights therein (a "Sale"), then Parent shall cause to be paid to the Company
(in cash or in the form of the other consideration, if any, received by Parent
pursuant to the Sale), the amount by which: (i) the Proceeds of such Sale,
exceeds (ii) the Aggregate Cost Amount with respect to the Option or the Option
Shares (as the case may be) subject to such Sale.  For purposes of this Section
4:

        (i)  The "Proceeds" of a Sale shall mean the aggregate amount of the
proceeds (in cash or in kind) paid to Parent or any of its affiliates pursuant
to such Sale (with any non-cash proceeds being valued at the fair market value
thereof).

        (ii) The "Aggregate Cost Amount" with respect to the Option shall be
equal to the aggregate amount of all costs (including, without limitation,
brokers fees and commissions, filing fees, legal fees, accounting fees, any
amounts paid or payable by Parent under Section 16(b) of the Exchange Act and
any taxes) paid or payable as a result of the Sale by Parent of the Option. The
"Aggregate Cost Amount" with respect to any Option Share shall be equal to the
sum of (A) the aggregate dollar amount paid by Parent or its affiliate(s) for
such Option Shares, (B) the aggregate amount of all costs (including, without
limitation, brokers fees and commissions, filing fees, legal fees, accounting
fees, any amounts paid or payable by Parent under Section 16(b) of the Exchange
Act and any taxes) paid or payable as a result of the acquisition or Sale of
such Option Shares, and (C) interest at the rate of 7% per annum on the dollar
amount referred to in clause "(A)" of this sentence (for the period commencing
as of the date such Option Shares were acquired by Parent and ending on the date
of the Sale of such Option Shares).

<PAGE>
 
     (c) During the 180-day period commencing 270 days after the acquisition, if
any, by Parent of the Option Shares, the Company may (to the extent lawfully
permitted) elect to repurchase any or all of the Option Shares held by Parent or
any other Person at a price equal to the Aggregate Cost Amount with respect to
the Option Shares to be repurchased; provided, however, that such 180-day period
shall be extended to the extent necessary to allow any applicable governmental
notification period to expire or be terminated and any required governmental
approval to be obtained.

     (d) Notwithstanding anything to the contrary contained in this Agreement, a
Sale shall not be deemed to have taken place in connection with any conversion
or exchange of the Option as contemplated by Section 4(b) hereof.

     5.  Listing.  If Company Stock or any other securities to be acquired upon
         -------
exercise of the Option are then listed on any national securities exchange or
national securities quotation system, the Company, upon the request of Parent,
shall promptly file an application to list the shares of Company Stock or other
securities to be acquired upon exercise of the Option on such national
securities exchange or national securities quotation system and shall use
reasonable efforts to obtain approval of such listing as promptly as
practicable.

     6.  Registration Rights.  The Company shall, if requested by Parent at any
         -------------------
time and from time to time within five years after the date of exercise of the
Option, as expeditiously as possible prepare and file up to two registration
statements under the Securities Act if such registration is necessary in order
to permit the sale or other orderly disposition of any or all securities that
have been acquired by exercise by Parent of the Option, in accordance with the
intended method of sale or other disposition stated by Parent, including a
"shelf" registration statement under Rule 415 under the Securities Act or any
successor provision; and the Company shall use its reasonable efforts to qualify
such securities under any applicable state securities laws; provided, however,
that the Company shall not be required to qualify to do business in or consent
to general service of process in, any jurisdiction by reason of this sentence.
Parent agrees to use reasonable efforts to cause, and to cause any underwriters
of any sale or other disposition to cause, any sale or other disposition
pursuant to such registration statement to be effected on a widely distributed
basis. The Company shall use reasonable efforts to cause each such registration
statement to become effective, to obtain all consents or waivers of other
parties which are required therefor, and to keep such registration statement
effective for such period not in excess of 90 calendar days from the day such
registration statement first  becomes effective as may be reasonably necessary
to effect such sale or other disposition. The obligations of the Company to file
a registration statement and to maintain its effectiveness may be suspended for
one or more periods of time not exceeding 60 calendar days in the aggregate (in
any 180 day period) with respect to any registration statement if the Board of
Directors of the Company shall have determined that the filing of such
registration statement or the maintenance of its effectiveness would adversely
affect the Company.  In the event of any suspension of any registration
statement, the Company agrees that the period of time during which the Company
is obligated to maintain the effectiveness of such registration statement shall
be extended for a period of time equal to the period during which such
suspension was in place.  Any registration statement prepared and filed under
this Section, and any sale covered thereby, shall be at the Company's expense

                                       4
<PAGE>
 
except for underwriting discounts or commission, brokers' fees and the fees and
disbursements of Parent's counsel related thereto. Parent shall provide all
information reasonably requested by the Company for inclusion in any
registration statement to be filed hereunder. If, during the time periods
referred to in the first sentence of this Section, the Company effects an
underwritten registration under the Securities Act of the Company's equity
securities for its own account or for any other of its stockholders (other than
on Form S-4 or Form S-8, or any successor form), it shall allow Parent the right
to participate in such registration; provided that, if the managing underwriters
of such offering advise the Company in writing that in their opinion the number
of securities requested to be included in such registration exceeds the number
which can be sold in such offering, priority shall be given to the securities
intended to be included therein by the Company for its own account and,
thereafter, the Company shall include the securities requested to be included
therein by Parent pro rata with the securities intended to be included therein
by other stockholders of the Company not having agreements giving them priority
in such registration. In connection with any registration pursuant to this
Section, Parent and the Company shall provide each other and any underwriter of
the offering with customary representations, warranties, covenants,
indemnification, and contribution in connection with such registration.
