                           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.

 
          (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

                                       2.

 
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 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
