                          FULL USE SUBLICENSE ADDENDUM

This document (the "Addendum") is between Oracle Corporation ("Oracle") and
Novistar, Inc. (the "Alliance Member") and shall be governed by the terms of the
Oracle Alliance Agreement between the Alliance Member and Oracle effective
February 18, 2000 (the "Agreement") and the terms set forth below.

1.   PROGRAM DISTRIBUTION

1.1  SUBLICENSE OF PROGRAMS AND TERMS

       The Alliance Member shall have the right to market and grant Sublicenses
     of Full Use Programs which are available in production release and listed
     on Oracle's Price List in effect at the time the Programs are ordered from
     Oracle to Sublicense to a Sublicensee; provided, however, the Alliance
     Member shall have no right to Sublicense any Programs designated as Oracle
     Applications Programs, Oracle Express Programs, Limited Production Programs
     or other Programs without the prior written consent of Oracle. The Alliance
     Member shall have the right to market and grant Sublicenses of Full Use
     Programs for use on Designated Systems in conjunction with the Integrated
     System to Sublicensees. Each copy of the Full Use Programs distributed
     shall be for the Sublicensee's own internal use in the Territory only on a
     single Designated System limited to a maximum number of Users.

       To acquire Programs for Sublicensing to Sublicensees, the Alliance Member
     shall order such Programs from Oracle. Each order shall specify the
     applicable Programs, maximum number of Users, computer/operating system
     configuration, fees, shipping location, and any other information required
     by Oracle for processing the order. Orders for Trial Sublicenses shall be
     clearly marked on the face of the Order Form.

1.2  DISTRIBUTION UNDER ORACLE AGREEMENT

       In addition to the Sublicense rights specified in Section 2.3.A of the
     Agreement and notwithstanding the terms of such Section and Section 2.3.B
     of the Agreement, the Alliance Member shall have the right to market and
     grant Sublicenses of Full Use Programs in conjunction with the Integrated
     System to Sublicensees under the then-current standard Oracle License
     Agreement which is located at http://alliance.oracle.com.

       With each order, the Alliance Member shall confirm that the Programs will
     be licensed to the Sublicensee subject to the terms of either an existing
     Software License and Services Agreement effective between the Sublicensee
     and Oracle, or the terms of the then-current standard Oracle License
     Agreement (the "Oracle Agreement").  As part of sublicensing under the
     Oracle Agreement, the Alliance Member shall obtain the Sublicensee's
     written or on-line agreement that the ordered Programs and services are
     subject to the terms and conditions of the Oracle Agreement.

       If the Sublicensee is a federal agency, the Alliance Member shall submit
     with each such order a written document executed by an authorized
     Sublicensee contracting officer which contains the following provision:
     "This is an open market order placed pursuant to terms identical to the
     terms and conditions of Oracle's General Services Administration (GSA)
     Schedule A Contract for Oracle Programs current as of the order date, with
     the exception of the maximum order limitations, discounts, maintenance,
     training units and other discounts specific to the applicable Oracle GSA
     Schedule.  No other pre-printed or reference terms and conditions shall
     apply."  This written document shall be deemed the applicable Oracle
     Agreement.

       The Alliance Member shall indemnify Oracle for any claims, damages, or
     losses arising from failure to obtain any Oracle Agreement.

       If the order specifies that the Programs are to be delivered to the
     Alliance Member, the Alliance Member shall have the right to re-deliver the
     Programs with their original packaging to the applicable Sublicensee.

1.3  FULL USE PROGRAMS

       For the purposes of this Addendum, "Full Use Programs" shall mean
     unaltered versions of the Programs with all functions intact.

1.4  VALUE-ADDED PACKAGE

       For the purposes of this Addendum, "Integrated System" shall mean the
     hardware and software products having Value-Added which are developed,
     sold, and/or licensed with the Programs to a Sublicensee by the Alliance
     Member to satisfy such Sublicensee's internal business requirements and
     objectives.  For purposes of the Agreement, the Integrated System will be
     regarded as the Alliance Member's Value-Added Package which is described in
     the attached Value-Added Attachment.  The Integrated System shall be
     regarded as "Value-Added" if the following materials are provided as part
     of the Integrated System by the Alliance Member:  (a) non-Oracle developed
     software; (b) customized programming or customized consulting; or (c) other
     computer products or components.

1.5  TRIAL SUBLICENSES

       The Alliance Member shall be entitled to grant, at no charge, up to ten
     (10) temporary Trial Sublicenses of the Programs at any one time. Such
     Sublicenses shall be for evaluation purposes only and shall be for a period
     not to exceed thirty (30) days.  The Alliance Member shall pay Oracle
     Sublicense fees for any Trial Sublicenses in excess of thirty (30) days.
     Each such Trial Sublicense shall be Sublicensed under a Sublicense
     agreement which provides for such trial use or under an Oracle Trial
     License Agreement, as the applicable Oracle Agreement.

1.6  NO DISTRIBUTORS

       The Alliance Member's right to market and grant Sublicenses of Full Use
     Programs hereunder shall be limited to the Alliance Member only.  The
     Alliance Member shall not appoint any third party to distribute the
     Programs without Oracle's prior written consent.
<PAGE>

1.7  DOCUMENTATION
       Oracle shall deliver one copy of the applicable Documentation with each
     order of Programs for Sublicensing to Sublicensees.

2.  SUBLICENSE FEES

2.1  SUBLICENSE FEES AND RATE

       For each copy of the Programs Sublicensed by the Alliance Member, the
     Alliance Member agrees to pay Oracle a Sublicense fee for each such
     Program, as specified in the applicable Price List and Alliance Member
     Price List supplement to such Price List in effect at the time the
     applicable Programs are Sublicensed to a Sublicensee.  Alliance Member's
     Sublicense fee shall be discounted in accordance with the Discount Schedule
     for License and Technical Support Fees attached hereto as Exhibit A.  The
     Sublicense fee shall be calculated effective on the date of the Sublicense,
     which shall be the date the Programs are shipped by Oracle or the effective
     date of the order to Oracle for such Programs, if no shipment is required.

       Fees for Sublicense of Programs shall be due and payable thirty (30) days
     from the invoice date. The Alliance Member shall not be relieved of its
     obligation to pay Sublicense fees owed to Oracle by the nonpayment of such
     fees by the Sublicensee.

2.2  PRICE LIST

       As set forth in the Agreement, the applicable Price List for determining
     Sublicense fees shall be the standard Price List in effect at the time the
     Program is Sublicensed to a Sublicensee.  However, pricing for any federal
     agency, pursuant to terms and conditions identical to the terms and
     conditions of Oracle's GSA Schedule A Contract for Oracle Programs current
     as of the order date, shall be based on Oracle's published GSA Price List.

       Notwithstanding any other provision of this Agreement, if the Alliance
     Member issues a written Sublicense quote and such quote is accepted by the
     applicable Sublicensee, for a period of ninety (90) days after the date of
     submission of the quote to the Sublicensee, the fee applicable to the
     Programs identified in the quote shall be based on the Price List in effect
     on such date.

2.3  USERS

       The fees for Sublicense of a Program shall be based and priced on the
     applicable User Level for the maximum number of Users for such Program, as
     specified in the Price List.  The Alliance Member shall have the right to
     Sublicense on any User basis specified in the Price List in effect at the
     time the applicable Program is Sublicensed to a Sublicensee.

3.   TERM

       This Addendum shall become effective on the Effective Date of this
     Addendum and shall be valid for three (3) years (the "Term"), unless
     terminated as provided in the Agreement. Any renewal of this Addendum shall
     be subject to renegotiation of terms and fees.

4.   TERRITORY

       The Alliance Member shall have the right to market and grant Sublicenses
     of Full Use Programs in the United States only (the "Territory").

5.   TECHNICAL SUPPORT

5.1  TECHNICAL SUPPORT FOR SUBLICENSEES

       A Sublicensee may acquire Technical Support services for Full Use
     Programs Sublicensed under this Addendum from Oracle at Oracle's standard
     rates and fee in effect at the time such Technical Support services are
     ordered under an Oracle Technical Support Services Agreement or Oracle
     Agreement, as applicable.

5.2  TECHNICAL SUPPORT FEES

       Oracle agrees that the Alliance Member shall have the right to offer
     Oracle annual Technical Support services to Sublicensees in the United
     States that are currently acquiring Full Use Programs. The Alliance Member
     shall only offer Oracle Technical Support services with respect to the
     initial first year of Technical Support for a Sublicensed Program. The
     Alliance Member shall only offer Oracle annual Technical Support services
     to a Sublicensee provided that:

     A.  Oracle receives from the Sublicensee an executed, standard Oracle
         Technical Support Services Agreement, Oracle Agreement, or other terms
         to govern the Technical Support services as agreed to in writing by
         Oracle and the Sublicensee;

     B.  The Full Use Programs are currently Sublicensed by the Alliance Member;

     C.  The Alliance Member pays Oracle its required Sublicense fee for the
         applicable Sublicensed Programs as provided under the Agreement, and
         the Alliance Member pays Oracle the applicable Technical Support
         services fees as set forth herein in advance;

     D.  The Alliance Member's Sublicense of the Full Use Programs coincides
         with the agreement to provide Technical Support Services for such
         Programs; and

     E.  The net Technical Support services fees represent new Technical Support
         revenue to Oracle.

       The Technical Support services fees payable by Alliance Member as
     provided above shall be Oracle's standard rates for such services as
     provided under the Price List in effect at the time the Technical Support
     services are ordered, discounted in accordance with the Discount Schedule
     for License and Technical Support Fees attached hereto as Exhibit A.

6.   SUBLICENSE REPORTS

       With each order for Programs for Sublicense to a Sublicensee, the
     Alliance Member shall send Oracle a report detailing for each Sublicensed
     Full Use Program: Sublicensee name, address, make/model and operating
     system of the Designated System, Full Use Programs, maximum number of
     licensed Users, whether the Sublicense is a Trial Sublicense, total Program
     fees and Technical Support Fees due to Oracle and specific descriptions of
     the Integrated System and Value-Added.

7.   ADDITIONAL LICENSES

       During the Term, the Alliance Member may order production release
     versions of Oracle off-the-shelf Programs available as production release
     as of the Effective Date of this Addendum and listed on the Price List in
     effect as of such date. The license fee for Development Licenses shall be
     equal to Oracle's standard list license fees in effect when an order is
     placed. The Alliance Member shall have the right to order Programs for use
     as Marketing Support Licenses at no further charge to the Alliance Member.
     The Alliance Member may obtain Technical Support services from Oracle for
     such Programs under Oracle's applicable Technical Support fees and policies
     in effect when such services are ordered.

        Date, as follows:

        i. to use the Programs solely for Customer's operations on the
           Designated System or on a backup system if the Designated System is
           inoperative, consistent with the use limitations specified or
           referenced in this Agreement, an Order Form, or the Documentation.
           Customer may not relicense, rent or lease the Programs or use the
           Programs for third-party training, commercial  time-sharing or
           service bureau use;

        ii.  to use the Documentation provided with the Programs in support of
             Customer's authorized use of the Programs;

        iii. to copy the Programs for archival or backup purposes, and to make
             a sufficient number of copies for the use specified in the Order
             Form.  All titles, trademarks, and copyright and restricted rights
             notices shall be reproduced in such copies;

        iv.  to modify the Programs and combine them with other software
             products; and

             in accordance with the terms of this Agreement.

        Customer shall not copy or use the Programs (including the
        Documentation) except as specified in this Agreement or an Order Form.
        Customer shall have no right to use any other software program that may
        be delivered with ordered Programs.

     B. Customer agrees not to cause or permit the reverse engineering,
        disassembly or decompilation of the Programs, except to the extent
        required to obtain interoperability with other independently created
        software or as specified by law.

     C. Oracle shall retain all title, copyright and other proprietary rights in
        the Programs.  Customer does not acquire any rights, express or implied,
        in the Programs, other than those specified in this Agreement.

2.2. TRANSFER AND ASSIGNMENT

     A. Customer may transfer a Program license within its organization upon
        notice to Oracle; transfers are subject to the terms and fees specified

     shall furnish Oracle with a signed certification verifying that the
     Programs are being used pursuant to the provisions of this Agreement and
     applicable Order Forms.

     Oracle may audit Customer's use of the Programs.  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 Oracle, Customer shall be
     invoiced for such underpaid fees.  Audits shall be conducted no more than
     once annually.

III. TECHNICAL SERVICES

3.1. TECHNICAL SUPPORT SERVICES

     Technical Support services ordered by Customer will be provided under

     is ordered.

3.2. CONSULTING AND TRAINING SERVICES

     be billed on a time and materials basis unless the parties expressly agree
     otherwise in writing.

3.3. INCIDENTAL EXPENSES

     For any on-site services requested by Customer, Customer shall reimburse
     Oracle for actual, reasonable travel and out-of-pocket expenses incurred.

IV.  TERM AND TERMINATION

4.1. TERM

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

4.2. TERMINATION BY CUSTOMER

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

4.3. TERMINATION BY ORACLE

     Oracle may terminate this Agreement or any license upon written notice if
     Customer materially breaches this Agreement and fails to correct the breach
     within 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 shall survive termination of this
     Agreement.  Upon termination, Customer shall cease using, and shall return
     or destroy, all copies of the applicable Programs.

V.   INDEMNITY, WARRANTIES, REMEDIES

5.1. INFRINGEMENT INDEMNITY

     Oracle will defend and indemnify Customer against a claim that the Programs
     infringe a copyright or patent or other intellectual property right,
     provided that: (a) Customer notifies Oracle in writing within 30 days of
     the claim;  (b) Oracle has sole control of the defense and all related
     settlement negotiations; and (c) Customer provides Oracle with the
     assistance, information and authority necessary to perform Oracle's
     obligations under this Section.  Oracle will reimburse Customer's
     reasonable out-of-pocket expenses incurred in providing such assistance.
     Oracle shall have no liability for any claim of infringement based on use
     of a superseded or altered release of Programs if the infringement would
     have been avoided by the use of a current unaltered release of the Programs
     which Oracle provides to Customer.

     If the Programs are held or are believed by Oracle to infringe, Oracle
     shall have the option, at its expense, to (a) modify the Programs to be
     noninfringing; or (b) obtain for Customer a license to continue using the
     Programs.  If it is not commercially reasonable to perform either of the
     above options, then Oracle may terminate the license for the infringing
     Programs and refund the license fees paid for those Programs.  This Section
     5.1 states Oracle's entire liability and Customer's exclusive remedy for
     infringement.

5.2. WARRANTIES AND DISCLAIMERS

     A. Program Warranty

                  Oracle warrants for a period of one year from the Commencement

     Programs or services, then such taxes shall be billed to and paid by
     Customer. This Section shall not apply to taxes based on Oracle's income.

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 Programs, the terms and
     pricing under this Agreement, and all information clearly identified 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.   Customer shall not disclose
     the results of any benchmark tests of the Programs to any third party
     without Oracle's prior written approval.

     The parties agree to hold each other's Confidential Information in
     confidence during the term of this Agreement and for a period of two years
     after termination of this Agreement. 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

     This Agreement, and all matters arising out of or relating to this
     Agreement, shall be governed by the laws of the State of California.

7.3. JURISDICTION

     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.  Oracle and Customer agree to submit to the
     jurisdiction of, and agree that venue is proper in, these courts in any
     such legal action or proceeding.

7.4. NOTICE

     All notices, including notices of address change, required to be sent
     hereunder shall be in writing and shall be deemed to have been given when
     mailed by first class mail to the first address listed in the relevant
     Order Form (if to Customer) or to the Oracle address on the Order Form (if
     to Oracle).

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

7.5. LIMITATION OF LIABILITY

     IN NO EVENT SHALL EITHER PARTY BE LIABLE FOR ANY INDIRECT, 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.  ORACLE'S LIABILITY FOR DAMAGES HEREUNDER
     SHALL IN NO EVENT EXCEED THE AMOUNT OF FEES PAID BY CUSTOMER UNDER THIS
     AGREEMENT, AND IF SUCH DAMAGES
<PAGE>

     RESULT FROM CUSTOMER'S USE OF THE PROGRAM OR SERVICES, SUCH LIABILITY SHALL
     BE LIMITED TO FEES PAID FOR THE RELEVANT PROGRAM OR SERVICES GIVING RISE TO
     THE LIABILITY.

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

     the remaining provisions of this Agreement will remain in full force.

7.7. WAIVER

     The waiver by either party of any default or 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 Oracle's proprietary rights
     in the Programs, no action, regardless of form, arising out of this
     Agreement may be brought by either party more than two years after the
     cause of 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
     Programs 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
     supersedes 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 a 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 Oracle-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.

The Effective Date of this Agreement shall be _______________________.

                                 Amendment One
                                    to the
                Oracle Software License and Services Agreement
                                    between
                              Oracle Corporation
                                      and
                                Novistar, Inc.

This document ("Amendment One"), amends the Oracle Software License and Services
Agreement (the "Agreement") between Oracle Corporation, a Delaware corporation
("Oracle") and Novistar, Inc., a Delaware corporation ("Customer"), dated
February 18, 2000:

Amend the Agreement as follows:

        1. In Section 2.1(A)(i), delete the words "on the Designated System or
           on a backup system, if the Designated System is inoperative".

        2. In Section 6.2, at the end of the last sentence, after "Oracle's
           income", add ", real estate, or capital stock".

        3. Add the following new Section 7.10:

           "7.10 Source Code Escrow
           Oracle shall retain in escrow a copy of the source code necessary to
           support the Programs. The current escrow agent is Data Securities
           International. The escrowed material shall be maintained under an
           agreement which provides that if Oracle ceases to be in the business
           of supporting the Programs, the escrow agent shall furnish the
           Customer with a copy of the escrowed material that has become
           unsupported. Customer shall pay the escrow agent a nominal fee
           sufficient to cover the cost of reasonable administrative expenses,
           including reproduction and distribution. Any escrowed material
           furnished under this provision shall be considered subject to the
           terms and conditions of this Agreement, and shall be used solely to
           maintain the Programs."

Subject to the modifications of this Amendment One, the Agreement shall remain
in full force and effect.

The Effective Date of this Amendment One is February 18, 2000.
