3    JOINT OFFERING DESCRIPTION.

     3.1  DEFINITION.

          For purposes of this Agreement, a Joint Offering shall mean the
     technical solution that is offered jointly by the Parties to their
     customers as described in this Section 3 and in Exhibit C-1, as such
     Exhibit C-1 may be modified from time to time pursuant to the procedure set
     forth in Section 3.2.

     3.2  GENERAL.

          The technical description of the Joint Offering is attached hereto as
     Exhibit C-1 and shall be the basis of the detailed Statements of Work to be
     incorporated into the Joint Development Agreement. Such technical
     description incorporates a detailed explanation of the material functions
     of each technical component. The Joint Offering, and its technical
     components may be modified by the Development Committee to respond to
     technical demand and market needs in order to maintain the competitiveness
     of the Joint Offering provided that all modifications adopted by the
     Development Committee are approved in writing by the Executive
     Representatives. Only the components described in Exhibit C-1, as modified
     from time to time by the Development Committee upon the written approval of
     both of the Executive Representatives, shall be considered part of the
     Joint Offering and subject to, without limitation, the provisions of
     Sections 5, 7 or 13. In addition to the Joint Offering, the Parties may
     cooperate to offer jointly to their customers additional components and/or
     services provided that such offer shall under no circumstances modify the
     definition of the Joint Offering (and therefore the rights and obligations
     of each Party under this Agreement) unless such components and/or services
     are made part of the Joint Offering in accordance with the procedure
     described above. [*]

4    JOINT DEVELOPMENT.

          The Parties shall jointly develop technology to integrate the SAP
     Applications and C1 Technology as part of the Joint Offering. The Parties
     shall form one or more joint development teams for such efforts, and, in
     each case, one Party shall be specifically designated to lead the related
     development effort under the guidance and review of the Development
     Committee. The costs of such development efforts shall be borne by the
     Party incurring such costs, unless otherwise agreed.

     4.2 BUSINESS PARTNERS.

          The development may incorporate business partners that are mutually
     acceptable to the Parties. [*] In each case, the roles and responsibilities
     of each business partner shall be mutually agreed to by the Parties. Unless
     otherwise agreed in writing, each Party is responsible for any fees or
     obligations owed to its own business partners.

     4.3 DEVELOPMENT APPROACH.

          During the term of this Agreement, development shall proceed by way of
     a phased approach, consisting of several defined implementation phases [*].
     To the extent feasible, joint development activities shall occur at the
     Parties' offices in the San Francisco Bay area. However, the Parties
     acknowledge that some development activities for which SAP is primarily
     responsible may occur in Walldorf, Germany or in any office maintained by
     SAPMarkets. Each Party shall keep the other Party closely informed through
     regular reports to the Development Committee of any development activities
     relating to Marketplace Portals, including the location of such activity.
     The Development Committee shall create a document retention policy related
     to each Party's development efforts.

     4.4 OWNERSHIP RIGHTS; LICENSING RIGHTS.

          The Joint Offering and the Electronic Procurement Applications shall
     be branded with a newly created product name which shall be adopted by the
     Executive Committee. Each Party shall be free to utilize the newly created
     product name in conjunction with its own trademarks to identify the Joint
     Offering and the Electronic Procurement Applications. This branding shall
     appear prominently in any Marketplace Portals using the Joint Offering and
     the Electronic Procurement Applications as licensed by any of the Parties
     provided that the customer permits display of branding on its Marketplace
     Portal. The new product name shall be jointly owned by the Parties. The
     Parties shall mutually agree on the necessary steps to protect the
     ownership in and to, and use of, the new product names as an identifier of
     the Joint Offering and the Electronic Procurement Applications. The
     principles set forth herein shall apply to any joint brand developed by the
     Parties during the term of this Agreement for any product or class of
     products.

     AGREEMENT.

23   CONFIDENTIALITY.

     23.1 CONFIDENTIAL INFORMATION.

          As used herein, "Confidential Information" shall mean, without
     limitation, any non-public communications, written or oral, involving a
     Party's non-public business information, technical information or data,
     however embodied, marketing plans, financial information and strategic
     plans or any other information identified in writing as confidential or
     proprietary.

     23.2 CONFIDENTIALITY OBLIGATIONS.

          The Parties hereby covenant and agree that, except as required by law
     and as provided in this Section, they shall not disclose the terms and
     conditions of this Agreement (including, but not limited to, the names of
     the Parties and the payment terms) to any other person or entity (other
     than their counsel and auditors) without obtaining the prior written
     consent of the other Party, except to the extent necessary to effect the
     transactions and actions contemplated herein.

          Each Party may furnish to the other Party in connection with this
     Agreement certain Confidential Information. The Party disclosing such
     Confidential Information is referred to as the "Discloser", and the Party
     receiving such Confidential Information is referred to as the "Recipient."
     Each Party agrees that it shall keep in confidence and prevent the
     acquisition, disclosure, use or misappropriation by any person or persons
     of Confidential Information which is received from the other under this
     Agreement, provided, however, that neither Party shall be liable for
     disclosure of any such information if the same is disclosed with the prior
     written approval of the other Party. Each Party agrees that if it breaches
     the provisions of this section, the Discloser of the Confidential
     Information may suffer irreparable injury and shall be entitled to seek a
     temporary and permanent injunction, in addition to the other remedies for
     breach of the Agreement.

          Recipient shall use the same care and discretion to avoid disclosure,
     publication or dissemination of Confidential Information as it uses with
     its own similar confidential information that it does not wish to disclose,
     publish or disseminate provided that Recipient shall use at least
     reasonable care. The Confidential Information is not to be disclosed to any
     persons other than the employees of the Recipient who have a need to know.
     Except as expressly provided by this Agreement, Recipient shall not use
     Confidential Information in any manner, nor use it for the benefit of
     anyone but Discloser.

          The obligations of Recipient with respect to any particular portion of
     Confidential Information shall terminate or shall not attach, as the case
     may be, when any of the following occurs: (i) it was in the public domain
     at the time of Discloser's communication thereof to

          Recipient; (ii) it entered the public domain through no fault of
          Recipient subsequent to the time of Discloser's communication thereof
          to Recipient; (iii) it was in Recipient's possession free of any
          obligation of confidence at the time of Discloser's communication
          thereof to Recipient; (iv) it was independently developed by
          Recipient; or (v) its disclosure is required pursuant to applicable
          law (including securities laws) or by a court or government order and
          Discloser has been given reasonable notice of such order and a
          reasonable opportunity to seek a protective order.

                  All such Confidential Information shall remain the exclusive
         property of Discloser. The confidentiality obligations shall survive
         any termination of this Agreement and shall continue for so long as the
         Confidential Information is the property of Discloser or for as long as
         otherwise permitted by law.

24       AUDIT RIGHTS.

         C1 and SAP agree to allow mutually acceptable independent CPA auditors,
which auditors shall not be compensated on a contingency basis and shall be
bound to keep all information confidential except as necessary to disclose
discrepancies to the other Party, to audit and analyze relevant accounting
records of each other to ensure compliance with all terms of this Agreement. Any
such audit shall be permitted within thirty (30) days of one Party's receipt
from the other of a written request to audit, during normal business hours, at a
time mutually agreed upon. The cost of such an audit shall be borne by the
requesting Party unless a material discrepancy is found, in which case the cost
of the audit shall be borne by the other Party. [*] Audits shall occur no more
frequently than once per calendar year and shall not interfere unreasonably with
the audited Party's business activities and shall be conducted in the audited
Party's facilities during normal business hours on reasonable notice. An audit
may cover any period; provided that: (i) the period has not been previously
audited; and (ii) the period under audit is within [*] immediately preceding the
commencement of the audit. A Party shall promptly reimburse the other for the
amount of any discrepancy arising out of such audit which indicates that such
Party is owed amounts hereunder as well as the costs of the audit, if
applicable, as provided above. Any dispute pursuant to this provision is subject
to the provisions of Section 30.12 hereof.

         For a period of at least [*] following the date of termination or
expiration of this Agreement, C1 and SAP shall keep available for inspection by
SAP or C1 (as applicable) and its representatives for any reasonable purpose
all records, files, documents and correspondence relating to the Joint Offering.

25   TERM & TERMINATION.

     25.1 TERM.

     Executive Committee, Development Committee, or Sales and Marketing
     Committee remains unresolved after completion of the dispute resolution
     procedures identified in Section 11.6.

     25.6     TERMINATION FOR A CHANGE OF CONTROL.

          SAP may terminate this Agreement within three months of the occurrence
     of any of the following transactions by C1 with a Competitor of SAP: (i) a

     29   STATUS.

          29.1    C1 STATUS.

                  In connection with this Agreement, C1 is an independent
         contractor and as such will not have any authority to bind or commit
         SAP. Nothing herein shall be deemed or construed to create a joint

         Parties for any purpose. C1 shall provide all personnel required to
         perform its obligations hereunder, which personnel may in some
         instances be employees of C1 and in other instances may be independent
         contractors hired by C1 for the purpose of performing specific
         obligations pursuant to this Agreement. In either such event, however,
         C1 shall be responsible to SAP for the completion of the obligations to
         be performed pursuant to this Agreement and the persons performing such
         obligations as representatives of C1 shall perform such obligations
         under the direct control and supervision of C1 rather than SAP. Neither
         C1 nor any of the personnel utilized by C1 in performing its

         benefits made available to SAP's employees, nor shall such personnel be
         entitled to any direct or indirect compensation or remuneration of any
         kind from SAP as a result of the performance of this Agreement, except
         for C1's obligations to pay fees to SAP as per Section 13, and C1 shall
         be responsible for the compensation of such personnel.

     joint marketplace solution.

GEOGRAPHIC SCOPE

     The geographic scope of this agreement extends to all countries in which
     the SAP/C1 joint marketplace software is installed.

PRINCIPLE COMMITMENTS

     The support of the joint marketplace solution will be organized as follows:
     Level 1 is done by the customer, level 2 and level 3 see section `Support
     Level and Support Responsibilities'.

TERMS
     The parties named herewith agree to abide by the framework of cooperation
     outlined in this document. The parties agree to engage best effort in their
     endeavors to provide satisfactory services to the end-user on the joint
     marketplaces.
     Regular reviews will be held on a monthly basis among the Global Support
     Managers of C1 and SAP to evaluate and improve upon the service performance
     of the undersigned. The parties agree to review the terms and conditions of
     their respective support obligations within sixty (60) days from the
     Effective Date of the Agreement.

AVAILABILITY
     The interface to the marketplace support is made available to the end-users
     via the support button, hotline or e-mail address on the marketplace.

                                               vital business processes on the Marketplace. The case requires
                                               immediate processing as the breakdown can result in significant
                                               financial losses.

                                               to be set as "high" when there is a major  disruption  of normal
                                               business processes.
       ---------------------------------------------------------------------------------------------------------
             3       Medium                    Minor functional issue (e.g.  content,  bad links). A case is to
                                               be set as "medium"  when there is a minor  disruption  of normal
                                               business processes.

     The response times are calculated during availability hours only.

     b) Response times between SAP and C1

     SAP and C1 make best efforts to achieve the response times (see section
     response times a)). If it is necessary to transfer the case between SAP and
     C1 this happens as soon as possible, so that the other party has sufficient
     time for a resolution or an action plan. Both parties shall use reasonable
     efforts to assist the other party in resolving the customer cases.

ESCALATION PROCEDURES

     Escalation criteria The escalation procedure ("ESCALATION") will be
     followed if either party believes a Customer situation requires additional
     attention by the other party to resolve the problem. Escalation is
     triggered by the Customer or either party when:

     a.   the Customer is not satisfied with the progress of an issue; and
     b.   there is a significant impact to business operations or project
          implementation; and
     c.   high levels of Customer anxiety exist.

Escalation processes

     Either party's Escalation contact (see appendix D) or support consultant
     may call the other party's Escalation contact. The parties agree that
     escalation contacts (see appendix D) shall be available on a 24 hours, 7
     days a week basis to handle emergency situations. Once a party requests
     Escalation a

MUTUAL ACTION PLAN will be developed which defines the steps to resolve the
customer's problem. The steps are at minimum:

          a. address resources or increase them if already addressed,
          b. define responsibilities for each action,
          c. expected completion date of each action,
          d. Contingency/next steps if desired results are not achieved.

This action plan will be modified by mutual agreement among the designated
contacts as required by the situation.

The parties agree that on each party's reasonable request the other party shall
send support personnel to customer's site [*] to resolve escalated customer
cases. Such personnel shall be skilled in the minimum set of training described
in appendix C. [*]

When the customer states the problem is resolved or the situation no longer
requires Escalation, the Escalation is closed. Each party will exchange with the
other party the final reports summarizing the actions taken and results of these
actions, likelihood of problem recurrence and recommended future actions.

CALL TRACKING SYSTEM

     SAP and C1 will respectively provide access to their call tracking systems
     with the task that cases may be exchanged worldwide.

TECHNICAL SUPPORT INFORMATION DATABASE

     SAP and C1 will respectively provide access to their Technical Support
     Information Database. Each party posts any information about available
     patches and /or fixes into the table definitions. Each party shall grant
     the other party free of charge the right to those portions of its
     technical/support information database that are required for the
     fulfillment of the support duties. Neither party may license, transfer,
     sell, loan, distribute or otherwise provide the other party's
     technical/support information database or any portion thereof, to any third
     party, unless expressly agreed to in writing in advance by the parties.

PROACTIVE SERVICES/MONITORING/REMOTE CONNECTIVITY

     SAP and C1 analyze rules and architecture for the integration of the
     existing proactive service tools, methods and technologies. The parties
     work together on the development of an integrated solution which has to be
     available no later than one year from the date of this agreement.

TRAINING

     SAP and C1 agree that there is a minimum set of training described in
     appendix C. Each party provides one desk space in each major support
     center.

                           SENIOR MANAGEMENT AGREEMENT

         THIS SENIOR MANAGEMENT AGREEMENT (this "AGREEMENT") is made as of June
20, 2000 between Commerce One, a Delaware corporation (the "PARENT" or "COMMERCE
ONE"), and Ken S. Bajaj ("EXECUTIVE"), to be effective as of the Effective Time
(as defined in the Reorganization Agreement described below).

         WHEREAS, Executive and AppNet, Inc., a Delaware corporation (the
"COMPANY") have entered into a Senior Management Agreement, dated as of June 29,
1998 (the "APPNET SENIOR MANAGEMENT AGREEMENT"), pursuant to which Executive
purchased, and the Company sold, 3,566,000 shares of the Company's Common Stock,
par value $.0005 per share, (the "RESERVED STOCK").

         WHEREAS, as of the date of the AppNet Senior Management Agreement,
Executive owned 6,900,000 restricted shares of the Company's Common Stock, par
value $.0005 per share (the "CARRIED STOCK" and with the Reserved Stock,
collectively referred to as "EXECUTIVE STOCK").

         WHEREAS, the Parent, the Company, and Constitution Acquisition
Corporation, a Delaware corporation and a wholly-owned subsidiary of the Parent
("MERGER SUB"), and certain other parties have entered into an Agreement and
Plan of Merger and Reorganization dated of even date herewith (the
"REORGANIZATION AGREEMENT"), pursuant to which, among other things, the Merger
Sub shall merge with and into the Company (the "MERGER").

         WHEREAS, prior to the Effective Time of the Merger, the Company will
grant to the Executive a stock option to purchase 25,000 shares of Company
common stock at an exercise price per share equal to the then current fair
market value of one share of Company common stock on the date of grant (the
"COMPANY OPTION"). The Company Option will vest as to 25% of the shares subject
to the Company Option one (1) year after the date of grant, and as to an
additional 25% of the shares subject to the Company Option upon the expiration
of the second, third and fourth anniversaries, respectively, of the date of
grant, so that the Company Option will be fully vested and exercisable four (4)
years from the date of grant, subject to Executive's continued service to the
Company on the relevant vesting dates. Such Company Option will be subject to
the terms, definitions and provisions of the Company's stock option plan and the
stock option agreement by and between the Executive and the Company and will not
contain any accelerated vesting provisions.

         WHEREAS, the Parent and Executive desire to enter into this Agreement
to provide for Executive's employment with the Parent following the Effective
Time.

         WHEREAS, the Parent desires to employ Executive and to have the benefit
of his skills and services, and Executive desires to be employed with the
Parent, on the terms and conditions set forth herein.

         WHEREAS, the term "Parent," as used in this Agreement, shall include
any current or future, direct or indirect Subsidiaries of Parent, including the
Company.

<PAGE>

         WHEREAS, the parties hereto desire to set forth herein the terms and
conditions of their agreements and understandings with respect to the foregoing.

         NOW, THEREFORE, the parties hereto agree as follows:

                     PROVISIONS RELATING TO EXECUTIVE STOCK

         1.   OWNERSHIP. Executive acknowledges that as of the date of this
Agreement he owns beneficially and of record certain shares of the Carried
Stock free and clear of all liens and encumbrances, except as set forth in
the Subscription Agreement between the Company and the Executive, dated
February 10, 1998 (the "SUBSCRIPTION AGREEMENT").

         2.   RESERVED STOCK. Pursuant to the provisions of Section 2 of the
AppNet Senior Management Agreement, Executive purchased, and the Company
sold, 3,566,000 shares of the Reserved Stock at a price of $0.1055 per share.

         3.   REPURCHASE OF RESERVED STOCK. The Company's right to repurchase
Reserved Stock expired upon the Company's initial Public Offering.

         4.   REPURCHASE OPTION.

              (a)  Executive acknowledges and agrees that, as of the
Effective Time, 526,419 shares of Carried Stock will be subject to repurchase
rights under Section 4 of the AppNet Senior Management Agreement (the
"UNVESTED STOCK"). In the event Executive voluntarily resigns from (other
than in response to a Forced Relocation (as defined below) or a reduction in
the Annual Salary as initially set in this Agreement) or is terminated for
Cause by the Parent or its Subsidiaries for any reason (a "SEPARATION"), a
percentage of the Unvested Stock (whether held by Executive or one or more of
Executive's transferees, other than the Parent) will be subject to
repurchase, in each case at the option of the Parent pursuant to the terms
and conditions set forth in this Section 4(a) (the "REPURCHASE OPTION").
Fractional shares shall be rounded to the nearest whole share. The percentage
of the Unvested Stock that will be subject to repurchase at the Executive's
Original Cost for such shares shall be calculated in accordance with the
following schedule (the "SUBJECT SHARES"):

              Effective Time until June 20, 2001                            50.00%

              Date immediately following the earliest to
              occur of:  (x) June 20, 2001, (y)
              termination of the Executive without Cause,
              or (z) termination by Executive due to
              Forced Relocation or a reduction in the
              Annual Salary as initially set in this
              Agreement, and continuing thereafter                           0.00%

</TABLE>

              (b)  The Parent must elect to purchase all or any portion of
the Subject Shares by delivering written notice (the "REPURCHASE NOTICE") to
the holder or holders of the Subject Shares within 90 days after the
Separation. The Repurchase Notice will set forth the number of Subject Shares
to be acquired from each holder, the aggregate consideration to be paid for
such shares and the time and place for the closing of the transaction. The
number of shares to be repurchased by the Parent shall first be satisfied to
the extent possible from the Subject Shares held by Executive at the time of
delivery of the Repurchase Notice. If the number of Subject Shares then held
by Executive is less than the total number of Subject Shares which the Parent
had elected to purchase, the Parent shall purchase the remaining shares
elected to be purchased from the other holder(s) of Subject Shares under this
Agreement, pro rata according to the number of Subject Shares held by such
other holder(s) at the time of delivery of such Repurchase Notice (determined
as nearly as practicable to the nearest share).

              (c)  The closing of the purchase of the Subject Shares pursuant
to a Repurchase Option shall take place on the date designated by the Parent
in the Repurchase Notice, which date shall not be more than one month nor
less than five days after the delivery of such notice. The Parent will pay
for the Subject Shares to be purchased by it pursuant to the Repurchase
Option by first offsetting amounts outstanding under any bona fide debts owed
by Executive to the Parent and will pay the remainder of the purchase price
by check or wire transfer of funds in the aggregate amount of the purchase
price for such shares. The Parent will be entitled to receive all sellers'
signatures to be guaranteed.

              (d)  Notwithstanding anything to the contrary contained in this
Agreement, all repurchases of Subject Shares by the Parent shall be subject
to applicable restrictions contained in the Delaware General Corporation Law
and in the Parent's and its Subsidiaries' debt and equity financing
agreements. If any such restrictions prohibit the repurchase of Subject
Shares hereunder which the Parent is otherwise entitled or required to make,

         5.   RESTRICTIONS ON TRANSFER OF EXECUTIVE STOCK. As of the
Effective Time, any restrictions on the Transfer of shares of Executive Stock
set forth in Section 5 of the AppNet Senior Management Agreement shall
terminate.

         6.   ADDITIONAL RESTRICTIONS ON TRANSFER OF EXECUTIVE STOCK.

              (a) LEGEND. Upon the Effective Time, and until such time as the
Executive Stock is fully vested and no longer subject to the Repurchase
Option under Section 4 of this Agreement, the certificates representing the
Executive Stock will bear the legend in substantially the following form:

              "THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE ALSO
              SUBJECT TO ADDITIONAL RESTRICTIONS ON TRANSFER, CERTAIN
              REPURCHASE OPTIONS AND CERTAIN OTHER AGREEMENTS SET FORTH IN A
              SENIOR MANAGEMENT AGREEMENT BETWEEN THE COMPANY AND AN
              EXECUTIVE OF THE COMPANY. A COPY OF SUCH AGREEMENT MAY BE
              OBTAINED BY THE HOLDER HEREOF AT THE COMPANY'S PRINCIPAL PLACE
              OF BUSINESS WITHOUT CHARGE."

              (b)  OPINION OF COUNSEL. No holder of Executive Stock may sell,
transfer or dispose of any Executive Stock (except pursuant to an effective
registration statement under the Securities Act, applicable laws of descent
and distribution or among Executive's Family Group) without first delivering
to the Parent an opinion of counsel (reasonably acceptable in form and
substance to the Parent) that neither registration nor qualification under
the Securities Act and applicable state securities laws is required in
connection with such transfer.

                        PROVISIONS RELATING TO EMPLOYMENT

         7.   EMPLOYMENT. The Parent agrees to employ Executive and Executive
accepts such employment for the period beginning as of the Effective Time and
ending upon his separation pursuant to Section 7(c) hereof (the "EMPLOYMENT
PERIOD"). Executive's employment with the Parent shall be on an "at will"
basis, whereby either Executive or the Parent, may terminate Executive's
employment at any time for any reason or no reason, without further
obligation or liability, except as otherwise provided in this Agreement.

              (a)  POSITION AND DUTIES. During the Employment Period,
Executive shall serve as an Executive Vice President of Commerce One, Inc.
and President of Commerce One Global Services and shall have the normal
duties, responsibilities and authority of an Executive Vice President of
Commerce One, Inc. and President of Commerce One Global Services, including,
without limitation, the responsibilities associated with all aspects of the
daily operations of the company and the completion and integration of any
acquisitions made by the Parent, subject to the power of the President of
Commerce One, Inc. and the Parent's Board of Directors (the "BOARD") to
expand or limit such duties, responsibilities and authority and to override
actions of an Executive Vice President of Commerce One, Inc. and President of
Commerce One Global Services. The corporate headquarters of Commerce One
Global Services shall be located in Bethesda, Maryland,

                                      -4-
<PAGE>

unless otherwise agreed to by Executive. Executive shall report to the Vice
Chairman and President of Commerce One, Inc. and Executive shall devote his
best efforts and his full business time and attention to the business and
affairs of the Parent and its subsidiaries.

              (b)  SALARY, BONUS AND BENEFITS. The Parent will pay Executive
a salary (the "ANNUAL SALARY") of $300,000 per annum, subject to any increase
as determined by the Board based upon the Parent's achievements of budgetary
and other objectives set by the Board. The Annual Salary shall be paid
periodically in accordance with the Parent's payroll practices and shall be
subject to the usual, required withholdings. Executive shall be eligible to
receive a bonus of up to fifty (50%) of the Annual Salary based upon the
Parent's achievement of budgetary and other objectives set forth by the
Board. Executive's Annual Salary for any partial year will be prorated based
upon the number of days elapsed in such year. In addition, during the
Employment Period, Executive will be entitled to such other benefits approved
by the Board and generally made available to the Parent's senior management.

              (c)  SEPARATION. Executive's employment by the Parent will
continue until Executive's resignation, disability (as determined by the
Board in its good faith judgment) or death or until the Board terminates
Executive's employment for any reason or without any reason; PROVIDED,
HOWEVER, that in the event of Executive's resignation, Executive agrees to
provide the Parent no less than 30 days prior written notice of such
resignation in order to allow for an orderly transition to Executive's
replacement. If the Employment Period is terminated by the Parent without
Cause or by Executive due to Forced Relocation or a reduction in the Annual
Salary as initially set in this Agreement, Executive shall have no further
rights or claims against the Parent or its Affiliates, except that he and his
eligible dependents shall be entitled to receive his life insurance, medical
insurance and disability insurance benefits (but no other fringe benefits or
perquisites), through the earlier of (i) the end of the Noncompete Period (as
defined below in Section 9(a)) or (ii) Executive's acceptance of full-time
employment with another employer (such payment is hereinafter referred to as
the "Severance Benefits"). The Severance Benefits will be provided in
accordance with the Parent's normal employment practices. If the Employment
Period is terminated due to death, then the medical insurance will be
continued through the next full calendar month following the month in which
the Executive died. If the Employment Period is terminated due to Disability,
then the medical insurance and disability insurance will be continued until
the last day of the six-month period following Disability.

         8.   CONFIDENTIAL INFORMATION.

              (a)  Executive acknowledges that the Parent and its
Subsidiaries are engaged in the business of developing, marketing, licensing
or selling software for e-commerce marketplaces or exchanges and related
services, including the business of acquiring businesses that provide such
software or services and operating those businesses after their acquisition
(the "BUSINESS"). Executive further acknowledges that the Business and its
continued success depend upon the use and protection of a large body of
confidential and proprietary information, and that he holds a position of
trust and confidence by virtue of which he necessarily possesses, has access
to and, as a consequence of his signing this Agreement, will continue to
possess and have access to, highly valuable, confidential and proprietary
information of the Parent and its Subsidiaries not known to the public in
general, and that it would be improper for him to make use of this
information for the benefit of

                                      -5-
<PAGE>

himself and others. All of such confidential and proprietary information now
existing or to be developed in the future will be referred to in this
Agreement as "CONFIDENTIAL INFORMATION." This includes, without specific
limitation, information relating to the nature and operation of the Business,
the persons, firms and corporations which are customers or active prospects
of the Parent during Executive's employment by the Parent, the Parent's
development transition and transformation plans, methodology and methods of
doing business, strategic, acquisition, marketing and expansion plans,
including plans regarding planned and potential acquisitions and sales,
financial and business plans, employee lists, numbers and location of sales
representatives, new and existing programs and services (and those under
development), prices and terms, customer service, integration processes
requirements, costs of providing service, support and equipment and equipment
maintenance costs. Confidential Information shall not include any information
that has become generally known to and available for use by the public other
than as a result of Executive's acts or omissions. Notwithstanding the
foregoing, this provision shall not apply to information which the receiving
party can demonstrate (i) is, at the time of disclosure to it, generally
known to the public; (ii) after disclosure of the information to it, is
published or otherwise becomes generally known to the public through no fault
of the receiving party; (iii) is in the possession of the receiving party at
the time of disclosure to it; (iv) is received from a third party having a
lawful right to disclose such information; or (v) is independently developed
by the receiving party without reference to Confidential Information of the
furnishing party.

              (b)  Disclosure of any Confidential Information of the Parent
shall not be prohibited if such disclosure is directly pursuant to a valid
and existing order of a court or other governmental body or agency within the
United States; provided, however, that (i) Executive shall first have given
prompt notice to the Parent of any such possible or prospective order (or
proceeding pursuant to which any such order may result) and (ii) Executive
shall, to the extent possible and legally permitted, afford the Parent a
reasonable opportunity to prevent or limit any such disclosure.

              (c)  During the Employment Period and for a period of five (5)
years thereafter, Executive will preserve and protect as confidential all of
the Confidential Information known to Executive or at any time in Executive's
possession or control. In addition, during the Employment Period and at all
times thereafter, Executive will not disclose to any unauthorized person or
use for his own account any of such Confidential Information without the
Board's consent. Executive agrees to deliver to the Parent at Executive's
Separation, or at any other time the Parent may request in writing, all
memoranda, notes, plans, records, reports or other documents (and copies
thereof) containing or otherwise relating to any of the Confidential
Information (including, without limitation, all acquisition prospects, lists
and contact information) which he may then possess or have under his control.
Executive acknowledges that all such memoranda, notes, plans, records,
reports and other documents are and at all times will be and remain the
property of the Parent.

              (d)  Executive will fully comply with any agreement reasonably
required by any of the Parent's Affiliates, business partners, suppliers or
contractors with respect to the protection of the confidential and
proprietary information of such entries.

         9.   NONCOMPETITION AND NONSOLICITATION. Executive acknowledges that
in the course of his employment with the Parent he will become familiar with
Confidential Information and that his services will be of special, unique and
extraordinary value to the Parent. Executive agrees that the

                                      -6-
<PAGE>

Parent has a protectable interest in the Confidential Information, goodwill
and specialized knowledge acquired by Executive during the course of his
employment with the Parent. Therefore, Executive agrees that:

              (a)  NONCOMPETITION. During the Employment Period and for a
period of twelve (12) months thereafter (the "NONCOMPETE PERIOD"), he shall
not, anywhere in the United States, directly or indirectly own, manage,
control, participate in, consult with, render service for, or in any manner
engage in the Business or any other business engaged in by the Parent that
Executive actively assisted with or was involved in the management or
operation of at the time of Separation.

              (b)  NONSOLICITATION. During the Noncompete Period, Executive
shall not directly or indirectly through another entity (i) induce or attempt
to induce any employee of the Parent or any of its Subsidiaries to leave the
employ of the Parent or such Subsidiary, or in any way interfere with the
relationship between the Parent or any of its Subsidiaries and any employee
thereof, (ii) hire any person who was an employee of the Parent or any of its
Subsidiaries within 180 days prior to the time such employee was hired by the
Executive, (iii) induce or attempt to induce any owner of a site location,
customer, supplier, licensee or other business relation of the Parent or any
of its Subsidiaries to cease doing business with the Parent or such
Subsidiary or in any way interfere with the relationship between any such
customer, supplier, licensee or business relation and the Parent or any of
its Subsidiaries or (iv) directly or indirectly acquire or attempt to acquire
an interest in any business relating to the business of the Parent or any of
its Subsidiaries and with which the Parent or any of its Subsidiaries has
entertained discussions or has requested and received information relating to
the acquisition of such business by the Parent or any of its Subsidiaries in
the two-year period immediately preceding a Separation.

              (c)  ENFORCEMENT. If, at the time of enforcement of Section 8
or 9 of this Agreement, a court holds that the restrictions stated herein are
unreasonable under circumstances then existing, the parties hereto agree that
the maximum duration, scope or geographical area reasonable under such
circumstances shall be substituted for the stated period, scope or area and
that the court shall be allowed to revise the restrictions contained herein
to cover the maximum duration, scope and area permitted by law. Because
Executive's services are unique and because Executive has access to
Confidential Information, the parties hereto agree that money damages would
be an inadequate remedy for any breach of this Agreement. Therefore, in the
event of a breach or threatened breach of Section 8 or Section 9 of this
Agreement, the Parent or any of its successors or assigns shall, in addition
to other rights and remedies existing in its favor, be entitled to specific
performance and/or injunctive or other relief in order to enforce, or prevent
any violations of, the provisions of Section 8 or Section 9 from any court of
competent jurisdiction.

              (d)  ADDITIONAL ACKNOWLEDGMENTS. Executive acknowledges that
the provisions of this Section are in consideration of: (i) employment with
the Parent and (ii) additional goods and valuable consideration are set forth
in this Agreement. Executive expressly agrees and acknowledges that the
restrictions contained in Section 8 and 9 do not preclude Executive from
earning a livelihood, nor do they unreasonably impose limitations on
Executive's ability to earn a living. In addition, Executive agrees and
acknowledges that the potential harm to the Parent or the non-enforcement of
Sections 8 or 9 outweighs any harm to the Executive of their enforcement by
injunction or otherwise. Executive acknowledges that he has carefully read
this Agreement and has

                                      -7-
<PAGE>

given careful consideration to the restraints imposed upon the Executive by
this Agreement, and is in full accord as to their necessity for the
reasonable and proper protection of Confidential Information. Executive
expressly acknowledges and agrees that each and every restraint imposed by
this Agreement is reasonable with respect to subject matter, time period and
geographical area.

              (d)  SEVERABILITY. Whenever possible, each provision of this

invalid, illegal or unenforceable in any respect under any applicable law or
rule in any jurisdiction, such invalidity, illegality or unenforceability
will not affect any other provision or any other jurisdiction, but this

              (e)  COMPLETE AGREEMENT. This Agreement, those documents
expressly referred to herein and other documents of even date herewith embody
the complete agreement and understanding among the parties and supersede and
