<PAGE>   3

               delayed), provided however that either party may assign this
               Agreement: (1) to a transferee of substantially all of the
               business operations of such party (whether by asset sale, stock
               sale, merger, reorganization, operation of law, or otherwise)
               unless such entity is a competitor of the other party, or (2) to
               any entity that is controlled by, or is under common control
               with, such party. This Agreement shall be binding upon, inure to
               the benefit of, and be enforceable by and against the respective

        that the Applications are being used pursuant to the provisions of this
        Agreement and applicable Order Forms. E.piphany may audit Customer's use
        of the Applications. Any such audit shall be conducted during regular
        business hours at Customer's facilities and shall not unreasonably
        interfere with Customer's business activities. If an audit reveals that
        Customer has underpaid fees to E.piphany, Customer shall be invoiced for
        such underpaid fees and shall also pay E.piphany for the cost of the
        audit if the underpayment exceeds 5% of fees due during the audited
        period. Audits shall be conducted no more than once annually.

III.    TECHNICAL SERVICES

IV.     TERM AND TERMINATION

4.1.    TERM

        If not otherwise specified on the Order Form, this Agreement and each
        Application license granted under this Agreement shall continue
        perpetually unless terminated under this Article IV.

4.2.    TERMINATION BY CUSTOMER

        Customer may terminate any Application license at any time; however,
        termination shall not relieve Customers obligations specified in Section
        4.4.

4.3.    TERMINATION BY E.PIPHANY

        E.piphany may terminate this Agreement or any Application license upon
        written notice if Customer materially breaches this Agreement and fails
        to correct the breach within thirty (30) days following written notice
        specifying the breach.

4.4.    EFFECT OF TERMINATION

        Termination of this Agreement or any license shall not limit either
        party from pursuing other remedies available to it, including injunctive
        relief, nor, shall such termination relieve Customer's obligation to pay
        all fees that have accrued or are otherwise owed by Customer under any
        Order Form. The parties' rights and obligations under Sections 2.1.B,
        2.1.C, and 2.2.B, and Articles IV, V, VI, and VII (excluding Section
        7.3) shall survive termination of this Agreement. Upon termination,
        Customer shall cease using, and shall return or destroy, all copies of
        the applicable Applications.

V.      INDEMNITY, WARRANTIES, REMEDIES

5.1.    INFRINGEMENT INDEMNITY

        E.piphany will defend and indemnify Customer against any, cost, expense
        (including reasonable attorneys fees incurred as a result of any third
        party claim that the Applications infringe a copyright, patent, trade
        secret or other intellectual property right, provided that: (a) Customer
        notifies E.piphany in writing within thirty (30) days of the claim; (b)
        E.piphany has sole control of the defense and all related settlement
        negotiations; and (c) Customer provides E.piphany with the assistance,
        information and authority necessary to perform E.piphany's obligations
        under this Section. E.piphany will reimburse Customer's reasonable
        out-of-pocket expenses incurred in providing such assistance. E.piphany
        shall have no liability for any claim of infringement based on use of a
        superseded or altered release of the Applications if the infringement
        would have been avoided by the use of a current unaltered release of the
        Applications provided that E.piphany has provided such release prior to
        the date of alleged infringement without charge to Customer.

                                      -4-
<PAGE>   5

        If the Applications are held or believed by E.piphany to infringe,
        E.piphany shall have the option, at its expense, to (a) modify the
        Applications to be noninfringing; or (b) obtain for Customer a license
        to continue using the Applications. If it is not commercially reasonable
        to perform either of the above options, (then E.piphany may terminate
        the license for the infringing Applications and refund the license fees
        paid for the Applications, prorated over a five (5) year term from the
        date of this Agreement). THIS SECTION 5.1 STATES E.PIPHANY'S ENTIRE
        LIABILITY AND CUSTOMER'S EXCLUSIVE REMEDY FOR INFRINGEMENT.

5.2.    WARRANTIES AND DISCLAIMERS

        A.     APPLICATION WARRANTY

               E.piphany warrants for a period of one (1) year from the
               Commencement Date that each Application licensed will perform
               substantially as described in the Documentation (unless modified
               by a party other than E.piphany in which case this warranty is
               void.) E.piphany warrants for a period of one (1) year from the
               delivery of any Upgrade, Patch or Enhancement (as defined in this
               Agreement and the Technical Services Agreement) that such
               Upgrade, Patch or Enhancement will perform substantially as
               described in the Documentation therefore if any.

        B.     MEDIA WARRANTY

               E.piphany warrants the tapes, diskettes or other media to be free
               of material defects in materials and workmanship under normal use
               for ninety (90) days from the Commencement Date.

        C.     SERVICES WARRANTY

               E-piphany warrants that its Technical Support, training and
               consulting services will be performed consistent with generally
               accepted industry standards. This warranty shall be valid for
               ninety (90) days from performance of service.

        D.     YEAR 2000 WARRANTY

               E.piphany warrants that Applications will be Year 2000 Compliant.
               "Year 2000 Compliant" means that Applications will perform
               without error, loss of data or loss of functionality arising from
               any failure to process, calculate, compare or sequence date data
               accurately if all associated products, such as hardware, software
               and firmware, used in combination with Applications properly
               exchange date data with Applications. In addition, Year 2000
               Compliant Applications will not cause any associated products or
               systems in which they may be used to fail in any of the ways
               described above. THIS WARRANTY SHALL NOT APPLY TO ANY THIRD PARTY
               PRODUCTS USED IN COMBINATION WITH APPLICATIONS.

               INCLUDING THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS
               FOR A PARTICULAR PURPOSE. E.PIPHANY DOES NOT WARRANT THAT THE
               APPLICATIONS WILL OPERATE IN COMBINATIONS OTHER THAN AS SPECIFIED
               IN THE DOCUMENTATION OR THAT THE OPERATION OF THE APPLICATIONS
               WILL BE UNINTERRUPTED OR ERROR-FREE. PRE-PRODUCTION RELEASES OF
               APPLICATIONS, COMPUTER-BASED TRAINING PRODUCTS ARE DISTRIBUTED
               "AS IS."

               The correction of Application errors that cause breach of the
               warranty, or if E.piphany is unable to make the Application
               operate as warranted, Customer shall be entitled to terminate the
               Application license and recover the fees paid to E.piphany for
               the Application license.

        B.     FOR MEDIA

               The replacement of defective media returned within ninety (90)
               days of the Commencement Date.

               The reperformance of the services, or if E.piphany is unable to
               perform the services as warranted, Customer shall be entitled to

               services.

5.4     ACKNOWLEDGEMENT

        Customer acknowledges that: (i) Customer has requested that E.piphany
        integrate the Applications with software and systems owned or licensed
        by Customer; (ii) Customer has valid existing rights to any and all such
        third party software and systems; (iii) E.piphany is not an agent or
        otherwise acting on behalf of any such third party licensor; and (iv)

        other right in such software or systems.

VI.     PAYMENT PROVISIONS

6.1.    INVOICING AND PAYMENT

VII.    GENERAL TERMS

7.1.    NONDISCLOSURE

        By virtue of this Agreement, the parties may have access to information
        that is confidential to one another ("Confidential Information").
        Confidential Information shall be limited to the Applications,
        Documentation, the terms and pricing under this Agreement, all
        information clearly identified as confidential, a parties' code,
        processes, architecture and any other information that may be accessed
        by a party hereunder that should reasonably be deemed as confidential. A
        party's Confidential Information shall not include information that: (a)
        is or becomes a part of the public domain through no act or omission of
        the other party; (b) was in the other party's lawful possession prior to
        the disclosure and had not been obtained by the other party either
        directly or indirectly from the disclosing party; (c) is lawfully
        disclosed to the other party by a third party without restriction on
        disclosure; or (d) is independently developed by the other party without
        reference to the Confidential Information. Customer shall not disclose
        the results of any benchmark tests of the Applications to any third
        party without E.piphany's prior written approval.

        The parties agree to hold each others Confidential Information in
        confidence for a period of five years after disclosure of the
        Confidential Information or for a period of two years after termination
        of this Agreement, whichever is earlier. The parties agree, unless
        required by law, not to make each other's Confidential Information
        available in any form to any third party for any purpose other than the
        implementation of this Agreement. Each party agrees to take all
        reasonable steps to ensure that Confidential Information is not
        disclosed or distributed by its employees or agents in violation of the
        terms of this Agreement.

7.2.    GOVERNING LAW AND JURISDICTION

                                      -7-
<PAGE>   8

        This Agreement, and all matters arising out of or relating to this
        Agreement, shall be governed by the laws of the State of California
        without reference to conflicts of laws principles. Any legal action or
        proceeding relating to this Agreement shall be instituted in a state or
        federal court in San Francisco or San Mateo County, California.

        that venue is proper in, these courts in any such legal action or
        proceeding.

7.3     PUBLICITY.

        Upon execution of the Agreement, E.piphany shall be entitled to
        represent that Customer is a customer, disclose that the parties have
        entered into an Agreement to the extent necessary to comply with SEC
        requirements and issue a press release mutually acceptable to the
        parties.

7.4.    NOTICES

        All notices, including notices of address change, required to be sent
        hereunder shall be in writing and shall be deemed to have been given

        relevant Order Form (if to Customer) or to the E.piphany address on the
        Order Form (if to E.piphany).

        To expedite order processing, Customer agrees that both parties may
        treat documents faxed one to the other as original documents;
        nevertheless, either party may require the other to exchange original
        signed documents.

7.5.    LIMITATION OF LIABILITY

        EXCEPT FOR E.PIPHANY'S OBLIGATIONS UNDER SECTION 5.1 (INFRINGEMENT

        INCIDENTAL, SPECIAL OR CONSEQUENTIAL DAMAGES, OR DAMAGES FOR LOSS OF
        PROFITS, REVENUE, DATA OR USE, INCURRED BY EITHER PARTY OR ANY THIRD
        PARTY, WHETHER IN AN ACTION IN CONTRACT OR TORT, EVEN IF THE OTHER PARTY
        HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. NEITHER PARTY'S
        LIABILITY FOR DAMAGES HEREUNDER SHALL EXCEED THE AMOUNT OF FEES PAID BY
        CUSTOMER UNDER THIS AGREEMENT.

        The provisions of this Agreement allocate the risks between E.piphany
        and Customer. E.piphany's pricing reflects this allocation of risk and
        the limitation of liability specified herein.

7.6.    SEVERABILITY

        If any provision of this Agreement is held to be invalid or
        unenforceable, the remaining provisions of this Agreement will remain in

<PAGE>   9

        The waiver by either party of any default of breach of this Agreement
        shall not constitute a waiver of any other or subsequent default or
        breach. Except for actions for nonpayment or breach of E.piphany's
        proprietary rights in the Applications, no action, regardless of form,
        arising out of this Agreement may be brought by either party more than
        two years after the cause of the action has accrued.

7.8.    EXPORT ADMINISTRATION

        Customer agrees to comply fully with all relevant export laws and
        regulations of the United States ("Export Laws") to assure that neither
        the Applications nor any direct product thereof are (1) exported,
        directly or indirectly, in violation of Export Laws; or (2) are intended
        to be used for any purposes prohibited by the Export Laws, including,
        without limitation, nuclear, chemical, or biological weapons
        proliferation.

7.9.    ENTIRE AGREEMENT

        This Agreement constitutes the complete agreement between the parties
        and supercedes all prior or contemporaneous agreements or
        representations, written or oral, concerning the subject matter of this
        Agreement. This Agreement may not be modified or amended except in
        writing signed by a duly authorized representative of each party; no
        other act, document, usage or custom shall be deemed to amend or modify
        this Agreement.

        It is expressly agreed that the terms of this Agreement and any Order
        Form shall supersede the terms in any Customer purchase order or other
        ordering document. This Agreement shall also supersede all terms of any
        unsigned or "shrinkwrap" license included in any package, media, or
        electronic version of E.piphany-furnished software and any such software
        shall be licensed under the terms of this Agreement, provided that the
        use limitations contained in an unsigned ordering document shall be
        effective for the specified licenses.

7.10.   FORCE MAJEURE

        Neither party shall be liable to the other for any delay or failure to
        perform any obligation under this Agreement if the delay or failure is

        party.

THE EFFECTIVE DATE OF THIS AGREEMENT SHALL BE MARCH 3, 2000.
