separate Statement of Work shall be sequentially numbered as EXHIBIT B
(e.g., EXHIBIT B-1, B-2, etc.).

          1.9  "UPDATES" shall mean new versions of the Software that Commerce
One makes available generally to customers of the Software as part of the
support described in Section 3 below.

     2.   SCOPE.

          2.1  RIGHT TO USE. Subject to the terms and conditions of this
Agreement, Commerce One grants NTT a limited, nontransferable license, without
right of sublicense, to install the Software at the Designated Sites (as
defined below) and to use the Software for internal business purposes only.
Additionally, NTT can provide access to MarketSite services to up to five (5)
external business partners during Phase II of this project. Further, it is
understood and agreed that beta versions of the Software provided hereunder to
NTT are still under development and are provided for


                                      -2-

<PAGE>


experimental, evaluation purposes only. Accordingly beta versions of the
Software shall not be used in a production or commercial environment. Unless
otherwise specified herein, NTT shall install the double byte enabled version
of the Software, if any, solely at the locations in Japan set forth in
EXHIBIT D (collectively, the "Designated Sites"). Commerce One will use
reasonable efforts to timely complete the development of the double byte
enabled version of the Software. NTT agrees that it will not itself, or
through any third party, modify the Software or reverse engineer,
disassemble, decompile or otherwise attempt to derive source code from the
Software; use the Software to provide services to third parties, whether in
commercial timesharing, rental or sharing arrangements, or otherwise use the
Software on a "service bureau" basis.

          2.2  COPIES. NTT shall not copy the Software, in whole or in part,
except for one (1) copy as necessary to archive such Software.

          2.3  INSTALLATION. NTT shall install or, where applicable, shall allow
Commerce One to install, the Software at the Designated Sites for use in
accordance with Section 2.1 above.

          2.4  INFORMATION. NTT shall provide information, including NTT
Confidential Information, as reasonably requested by Commerce One to ensure
compliance by NTT with the terms of this Agreement. In addition, and as a
condition of the grant of the license set forth in Section 2.1 above, NTT shall
permit Commerce One to operate "polling software" which monitors transactions
associated with the Software, and NTT shall at all times cooperate with Commerce
One to ensure that Commerce One has remote access to NTT's computers for such
purpose and that Commerce One's polling software operates correctly on NTT's
computers.

          2.5  EVALUATION. NTT will participate in a pilot program for the
Software in accordance with the criteria set forth in EXHIBIT D ("Pilot
Program"). NTT shall designate a test coordinator (the "Coordinator" as the
primary contact for Commerce One during the term of this Agreement with respect
to the Pilot Program). NTT will cooperate and consult with Commerce One in the
evaluation of the Software based on NTT's operation, use, and testing of the
Software pursuant to the Pilot Program Criteria set forth in EXHIBIT D. During
the term of the Pilot Program, if NTT discovers errors or bugs in the Software,
the Coordinator will promptly call Commerce One to report such problems.
Commerce One shall, at any time and in its sole discretion replace, modify,
alter, improve, enhance or change the Software and in such event the replaced
version shall be deemed part of the Software. If Commerce One provides NTT with
a corrected or updated Software, NTT shall promptly install such Software solely
as a version replacement and erase from memory any and all copies of the
previous Software. It is understood that any corrected or updated versions of
the Software shall be used solely as version replacements and shall not expand
the number or scope of licenses granted herein.

          2.6  EXCLUSIVITY.  During the period commencing on the Effective Date
and expiring on the later of (a) December 31, 1999 or (b) the expiration of
three (3) months following Commerce One's release of the MarketSite 3.0
version and the BuySite 6.0 version of the Software ("Exclusivity Period"),
Commerce One agrees that except for the entities listed in EXHIBIT E, Commerce
One will not license the localized Japanese language version of the BuySite
Software and/or the MarketSite Software, to third parties for use within the
Field of Use. For purposes of this Agreement, "Field of Use" shall mean use by
the licensee of the MarketSite and/or BuySite Software to provide services to
third parties having their principal place of business in Japan which services
are for the procurement of Indirect Materials for use by such third parties in
Japan. "Indirect Materials" means materials used in the day-to-day operation
of a buyer entity's business and which are more commonly referred to as
maintenance, repair and operations materials or "MRO" (e.g., desks, paper,
pencils, chairs) and specifically excluding materials that are directly
incorporated into the ultimate product or service


                                      -3-

<PAGE>


sold by such buyer entity to its customers. For the avoidance of doubt, it is
further understood and agreed that nothing in this Agreement or any of the
attachments hereto shall restrict Commerce One's ability to license the
Software to third parties for their own internal use in procuring goods or
services electronically on their own behalf for fulfillment of their own
internal business needs. Prior to entering into a definitive agreement during
the Exclusivity Period to license a localized Japanese language version of the
Software to a third party with its principal place of business in Japan for
use not within the Field of Use in Japan, Commerce One agrees to discuss with
NTT its possibility of participating with Commerce One in the sales process for
such Software.  If the parties do not reach an agreement within ten (10)
business days of notice of such transaction by Commerce One, Commerce One
shall have no further obligation under this Section, and Commerce One may
grant rights to or license the Software to third parties for use not within
the Field of Use. Upon the expiration of the Exclusivity Period, Commerce One
shall have the right to negotiate with any third parties regarding licensing
the Software, provided that Commerce One grants NTT the first right of
negotiation. Such first right of negotiation shall not preclude Commerce One
from negotiating with other third parties. This first right of negotiation
period shall expire three months from the date of the expiration of the
Exclusivity Period.

     3.   SUPPORT. During Phase II, Commerce One will make available to NTT,
without charge, such Software support including on-site and off-site support
as Commerce One makes available generally to its customers of the Software
located in Japan.

     4.   CONSULTING SERVICES.

          4.1  SERVICES. Commerce One shall use reasonable best efforts to
provide those services and/or deliver any Deliverables to NTT as set forth in
the applicable Statement of Work and NTT shall use reasonable efforts to
provide, or make available to Commerce One, free of charge, any information,
hardware or software resources or other materials of NTT, and assistance
reasonably required for the performance of such services and reasonable access
to NTT's facilities. Without limiting the foregoing, NTT shall use reasonable
efforts to perform those tasks and assume those responsibilities set forth in
the Statement of Work. The Statement of Work may also set forth certain
assumptions related to the services, and to the extent such assumptions are not
met or are inaccurate, the cost and schedule of the services may be affected.
NTT acknowledges and agrees that Commerce One's performance is dependent on
NTT's timely and effective satisfaction of all of NTT's responsibilities
hereunder and timely decisions and approvals by NTT. Commerce One is entitled to
rely on all decisions and approvals of NTT in connection with the services
provided hereunder. The information NTT has provided to Commerce One is true,
accurate and complete.

          4.2  PERFORMANCE. Commerce One warrants that the Services shall be
performed in a professional and workmanlike manner using persons with skills and
experience appropriate to their function.

          4.3  DELAYS. If NTT, or any third party acting on NTT's behalf, does
not provide any required item or service to Commerce One on a timely basis in
accordance with the applicable Statement of Work, then the dates set forth in
such Statement of Work which have been directly or indirectly affected by such
delay, shall be extended as reasonably necessary to account for such delay.


                                      -4-

          4.4  PROGRESS REPORTS; REVIEW MEETINGS. Commerce One will provide
to NTT progress reports regarding its work progress during development as set
forth in a Statement of Work or otherwise by mutual agreement. In addition,
the Project Managers (as defined below) shall participate in project review
meetings as set forth in a Statement of Work or otherwise by mutual
agreement. Any agreement reached among the parties at such meeting to modify
a Statement of Work shall be prepared in writing and duly signed by the
Project Manager of each party, and such revised Statement of Work shall be
binding upon the parties with respect to the subject matter thereof.

          4.5  SPECIFICATIONS. The parties will work in good faith to
complete the Specifications for each Deliverable within thirty (30) days
prior to the delivery date for such Deliverable specified in the Statement of
Work. Upon written approval of both parties to the final version of the
Specifications for a Deliverable, such final version shall be deemed the
"Specifications" for such Deliverable for purposes of this Agreement. If
after such good faith discussions, the parties do not agree upon the
Specifications for a Deliverable within such thirty (30) day period, either
may terminate this Agreement with respect to such Deliverable by forty-five
(45) days prior written notice to the other party within thirty (30) days
after the expiration of such time period.

          4.6  PROJECT MANAGERS. NTT and Commerce One shall each designate a
project manager who will be responsible for, and authorized to: (i) make
decisions regarding the Statement of Work; (ii) give any necessary approvals
in conjunction with the Statement of Work; and (iii) provide Commerce One
personnel with information and support for performance of the Statement of
Work.

          4.7  MODIFICATIONS TO STATEMENT OF WORK. Should NTT desire to
change the services specified in the Statement of Work, or request additional
services not included in the Statement of Work, NTT shall submit the proposed
modification in writing to Commerce One. Commerce One may, as determined by
Commerce One, elect to perform such modification or additional services, and
if Commerce One elects to perform such modifications or additional services,
Commerce One will provide NTT with a cost estimate and schedule impact for
performing the modifications and/or additional services in a revised
Statement of Work. Upon NTT's written acceptance of the revised Statement of
Work, Commerce One will proceed to perform the modifications mutually agreed
to by the parties.

          4.8  COMMENCEMENT CONDITION OF PHASE II: It is hereby understood and
agreed that Phase II shall be (i) commenced on or after NTT shall enter into a
certain letter of intent with its potential customer who desires to receive an
electronic procurement services from NTT by utilizing the localized Japanese
language version of the Software, and (ii) pursued by taking the needs and
requirements of the potential customer into due consideration. In case where
said letter of intent shall not be entered into between NTT and its potential
customer on or before the end of April, 1999, NTT and Commerce One shall
discuss in good faith and determine how to commence Phase II.

          4.9  PREFERRED STATUS. NTT will have the right to participate in
Commerce One's program for third party participation in periodic design
review meetings with Commerce


                                      -5-

<PAGE>

One's collaboration partners for the Software. In addition, Commerce One will
provide a dedicated Commerce One liaison to be located in Japan during Phase
II.

          4.10 All members of Commerce One Resource (as set forth on EXHIBIT
F) shall, while working at the Designated Sites, observe and abide by the
laws and regulations of the country having jurisdiction over such location,
and all rules and regulations applicable at the Designated Sites, as well as
any and all instructions given by NTT, provided that such instructions are
reasonable. Commerce One shall at its sole discretion provide all members of
Commerce One Resource with appropriate guidance and otherwise cause them to
observe the provisions of this Agreement including the preceding paragraph.

               NTT shall not be liable to Commerce One for any act or
omission of any member of Commerce One or for any accident while they are
staying at the Designated Sites or on the way to and from the Designated
Sites or to such personnel's home country. Commerce One, at its own cost,
shall subscribe to and maintain an insurance policy or policies covering any
accident referred to above, and any other appropriate property and liability
insurance for all members of Commerce One during their stay in the Designated
Sites.

               Nothing contained herein shall be construed as creating or
requiring any employment or labor relationship between NTT and any member of
Commerce One .

               When the services in each week are furnished, Commerce One
shall present a compiled weekly work sheet to NTT specifying works and dates
worked by each member of Commerce One Resource. Within seven (7) days after
receipt of the weekly work sheet, NTT shall verify the work sheet and issue
the accepted weekly work sheet to Commerce One. Should NTT fail to verify a
weekly work sheet, the services provided by Commerce One during the week in
question shall be deemed to have been accepted by NTT on the passage of said
seven (7) days. Should any defect or incorrectness be found in the work sheet
presented and so is pointed out by NTT, and agreed to as a defect or
incorrectness by Commerce One, Commerce One shall revise such defect or
incorrectness immediately and NTT shall verify and accept the revised work
sheet in the same way. It is hereby understood and agreed that NTT will not
accept any time stated in the work sheet as spent by a particular member of
Commerce One, if such work is not performed in accordance with this Agreement.

     5.   DELIVERY AND ACCEPTANCE.

          5.1  DELIVERABLES. Upon completion of each Deliverable, Commerce
One shall deliver such Deliverable to NTT.

          5.2  ACCEPTANCE PROCEDURE. Within twenty (20) days after receipt of
each Deliverable, NTT shall review, test and evaluate the Deliverable for
conformity with the Specifications and shall provide Commerce One with a
written acceptance of the Deliverable, or a written statement of defects to
be corrected. Commerce One shall promptly correct such defects, if any, and
return the Deliverable to NTT for retesting, review and reevaluation, and NTT
shall, within twenty (20) days of such redelivery, again provide Commerce One
with a list of defects which need to be corrected, if any. Failure of NTT to
provide Commerce One with a statement of acceptance or defects within the
applicable acceptance period shall be deemed


                                      -6-

<PAGE>

acceptance by NTT of the Deliverable. The foregoing procedure shall be
repeated until acceptance of each Deliverable by NTT; provided that if a
Deliverable is rejected five or more times by NTT and Commerce One has used
all reasonable efforts to correct the rejected Deliverable to bring it into
conformity with the Specifications, NTT will accept the Deliverables.
Notwithstanding the foregoing, Commerce One agrees to discuss with NTT the
possibility of redefining the specifications for the Deliverable.

          5.3  FINAL ACCEPTANCE. Upon NTT's acceptance of each Deliverable,
Commerce One shall promptly provide NTT with one (1) master copy of the
Deliverable for use in accordance with the terms of this Agreement. NTT shall
not remove any copyright, trademark or other Intellectual Property rights notice
placed by Commerce One on the master copies.

     6.   MARKETING. The parties agree to negotiate in good faith a definitive
agreement describing the commercial relationship between the parties for
establishment of an electronic procurement service utilizing the Software for
use within the Field of Use (as defined above) on pricing terms as favorable
as those pricing terms offered by Commerce One to any similarly situated third
party under a Comparable Marketing Agreement. For purposes of this Section,
"Comparable Marketing Agreement" means a marketing agreement that (i) exists
as of the effective date of the definitive agreement between NTT and Commerce
One, (ii) is for the same products and services and (iii) has substantially
the same scope, terms and conditions as the definitive agreement entered into
between NTT and Commerce One. It is understood that such definitive agreement
will contain an exclusivity provision as broad as that set forth in Section
2.6 above, subject to the parties' agreement on the scope of NTT's performance
obligations, as well as other terms and conditions to be negotiated in good
faith by the parties. If the parties do not enter into such a definitive
agreement by December 15, 1999 (the "Marketing Date"), neither party will be
under any further obligation to negotiate such an agreement and Commerce One
may grant rights to or license any or all of the Software to third parties
with no further obligations under this Section 6.

     7.   OWNERSHIP OF PROPRIETARY RIGHTS.

          7.1  SOFTWARE. The Software is protected by both United States
copyright law and international copyright treaty provisions. NTT agrees to
reproduce the Commerce One Intellectual Property rights notices and all other
legal notices, including but not limited to other proprietary notices and
notices mandated by governmental entities, on all complete or partial copies or
transmissions, if any, of the Software. As between Commerce One and NTT,
Commerce One or its licensors, as applicable, retain sole and exclusive
ownership of all right, title and interest in and to the Software and all
Intellectual Property rights relating thereto. In addition, Commerce One shall
own all rights in any copy, translation, modification, adaptation or derivative
work of the Software, and NTT hereby assigns all rights in them to Commerce One.
Without limiting the foregoing, NTT shall own all Intellectual Property rights
directly related to any additional features to the Software that NTT develops
independently and without input from Commerce Once, provided that the software
developed by NTT has a substantial use that does not infringe any Commerce One
patent rights. Without limiting the obligations set forth in Section 2.6 above,
if NTT files any patents or patent applications whose claims read on the
manufacture, sale or use of the Software, then NTT shall promptly give notice to
Commerce One in writing of such application or filing, and negotiate in good
faith a license grant to Commerce


                                      -7-

<PAGE>


One related to such claims made by NTT, including the right for Commerce One
to grant sublicenses to its customers and distributors, on reasonable and
customary terms and conditions to be negotiated in good faith between NTT and
Commerce One. NTT further agrees to assign all other modifications and
customizations to Commerce One that NTT develops in the exercise of all other
rights granted by Commerce One to NTT under this Agreement. NTT shall
physically identify the Software and any related materials as owned by
Commerce One. All rights not expressly granted hereuner are reserved by
Commerce One and its licensors. NTT shall physically identify the Software

Commerce One shall own all right, title and interest in and to the Commerce
One Technology. NTT hereby irrevocably assigns, and agrees to assign, to
Commerce One all of its right, title and interest in and to the Commerce One
Technology. NTT agrees to, and to cause its employees, agents and consultants
to, execute such documents and perform such acts, as may be reasonably
necessary to perfect Commerce One's rights as set forth in this Section 7 and
to obtain, enforce and defend Intellectual Property rights in and to the
Commerce One Technology.

          7.3  DELIVERABLES INCLUDING NTT CONFIDENTIAL INFORMATION. If NTT
provides Commerce One with any NTT Confidential Information as defined in
Section 11 below, Commerce One and NTT agree to discuss in good faith the
ownership of any Deliverables containing such NTT Confidential Information:
Provided however, NTT shall have no obligation to provide any NTT
Confidential Information if the parties cannot resolve such ownership to the
mutual satisfaction of both parties.

          7.4  RIGHT TO DEVELOP INDEPENDENTLY. Without limiting the intent of
Section 2.6 above, NTT understands and acknowledges that Commerce One is in
the business of developing products and providing consulting services similar
to those provided for NTT for other parties based upon the same tools and
knowledge base, and NTT agrees that nothing in this Agreement will impair
Commerce One's right to provide the same services or develop for itself or
others deliverables substantially similar to, or performing the same or
similar functions as, the Deliverables under this Agreement.

          7.5  USER GROUP. During the term of this Agreement, NTT will have
the right to participate in any "user group" forums which Commerce One may
establish from time to time for the purpose of exchanging information and
ideas regarding the establishment of similar electronic procurement services.

          8.1  LICENSE FEE. NTT shall pay Commerce One the nonrefundable,
noncreditable license fees ("License Fees") set forth in EXHIBIT F.

          8.2  SERVICE FEES. In consideration for performing the services
listed in the Statement of Work, NTT shall pay Commerce One the
nonrefundable, noncreditable service fees

                                      -8-

<PAGE>

("Service Fees") set forth on EXHIBIT F. All fees quoted and payments made
shall be in U.S. Dollars. Invoices shall be due and payable within forty-five
(45) days days of the receipt date of invoice. NTT shall reimburse Commerce
One for any out-of-pocket expenses, if accompanied by the payment evidence,
that are actually incurred by Commerce One in performing under each Statement
of Work.

          8.3  LATE PAYMENT AND TAXES.

               (a)  Any amounts due hereunder and not paid within forty-five
(45) days of the receipt date of invoice shall accrue interest at the rate of
one and one-half percent (1.5%) per month or the maximum rate permitted by
applicable law, whichever is less, determined and compounded on a daily basis
from the date due until the date paid. NTT shall be responsible for all sales
taxes, use taxes and similar taxes and charges of any kind imposed by any
federal, state or local governmental entity for products and/or services
provided under this Agreement, excluding only taxes based solely upon Commerce
One's net income.

               (b)  All payments by NTT specified hereunder are expressed as net
amounts and shall be made free and clear of, and without reduction for, any
withholding taxes. Any such taxes which are otherwise imposed on payments to
Commerce One shall be the sole responsibility of NTT. NTT shall provide Commerce
One with official receipts issued by the appropriate taxing authority or such
other evidence as is reasonably requested by Commerce One to establish that such
taxes have been paid. If Commerce One uses a foreign tax credit received by
Commerce One as a result of the payment of withholding taxes by NTT and thereby
reduces the amount of U.S. income tax that Commerce One otherwise would have
paid, Commerce One shall refund to NTT the amount of such reduction with respect
to such foreign tax credit.

     9.   INDEMNIFICATION.

          9.1  COMMERCE ONE INDEMNIFICATION. If an action is brought against NTT
claiming that the Software infringes any United States patent, or any copyright
or trade secret rights of a third party, Commerce One shall defend NTT and shall
pay the damages and costs finally awarded against NTT, or settlements entered
into by Commerce One on NTT's behalf, in the action, but only if (a) NTT
notifies Commerce One promptly and in writing upon learning that the claim might
be asserted, (b) Commerce One has sole control over the defense of the claim and
any negotiation for its settlement or compromise, and (c) NTT cooperates and
assists in the defense or settlement of the claim, as reasonably requested by
Commerce One. The indemnity set forth herein will not apply if and to the extent
that the infringement claim results from (a) a correction, modification or
unauthorized merged portion of the Software not provided by Commerce One, (b)
the failure to promptly install an update, (c) the combination of the Software
with items not provided by Commerce One, or (d) the performance of services or
development of customizations to the Software by Commerce One pursuant to a
specific design submitted by NTT.


                                      -9-

<PAGE>

     If NTT's use of the Software is enjoined by a court of competent
jurisdiction, or if Commerce One wishes to minimize its liability hereunder,
Commerce One may, at its option and expense, either (a) substitute a
substantially equivalent non-infringing item, (b) modify the infringing item
so that it no longer infringes but remains functionally equivalent, (c)
obtain for NTT the right to continue using such item, or (d) terminate the
licenses set forth herein with respect to the allegedly infringing Software
and refund the portion of the License Fees attributable to such Software.

WITH RESPECT TO INFRINGEMENT OR CLAIMS OF INFRINGEMENT OF ANY PATENT,
COPYRIGHT, TRADE SECRET OR OTHER INTELLECTUAL PROPERTY RIGHT BY THE SOFTWARE,
OR OTHERWISE ARISING OUT OF THIS AGREEMENT.

Commerce One from and against any damages and costs finally awarded against
Commerce One, or settlements entered into by NTT on Commerce One's behalf, in
connection with any claims, actions, suits or proceedings brought by third
parties arising out of or relating to the use by NTT of the Software, but
only if (a) Commerce One notifies NTT promptly and in writing upon learning
that the claim might be asserted, (b) NTT has sole control over the defense
of the claim and any negotiation for its settlement or compromise, and (c)
Commerce One cooperates and assists in the defense or settlement of the
claim, as reasonably requested by NTT. The indemnity set forth herein will
not apply if and to the extent that: (i) the claim, action, suit or
proceeding results from the negligence or willful misconduct of Commerce One
or any officer, director, employee, affiliate, agent, consultant or
representative of Commerce One, or breach of the Agreement by Commerce One or
any officer, director, employee, affiliate, agent, consultant or
representative of Commerce One; or (ii) it would be inconsistent with
Commerce One's indemnification obligations to NTT under Section 9.1.

     10.  LIMITATION OF LIABILITY.

          If either party shall sustain any damage due to any willful
misconduct or negligence by the other party or breach by the other party of
its obligations under this Agreement, the damage-sustained party shall be
entitled to claim, against the other party, recovery of actually proven
damage but only to the extent of damage which shall arise as direct
consequences thereof and to such limit not exceeding the total amount of fees
set forth in Section 8.1 and 8.2 above.

     IN NO EVENT WILL COMMERCE ONE OR ANY OF ITS LICENSORS BE LIABLE FOR ANY
CONSEQUENTIAL, INCIDENTAL, INDIRECT, SPECIAL OR PUNITIVE DAMAGES WHATSOEVER
(INCLUDING WITHOUT LIMITATION, DAMAGES FOR LOSS OF PROFITS, LOSS OF USE,
BUSINESS INTERRUPTION, LOSS OF DATA OR OTHER PECUNIARY LOSS), IN CONNECTION

EVEN IF COMMERCE ONE HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
THIS LIMITATION SHALL APPLY NOT WITHSTANDING ANY FAILURE OF THE ESSENTIAL
PURPOSE OF ANY LIMITED REMEDY PROVIDED HEREIN.

FAILURE OF THE ESSENTIAL PURPOSE OF ANY LIMITED REMEDY PROVIDED HEREIN.

     11.  CONFIDENTIALITY.

          "Confidential Information" of Commerce One means the Software, this
Agreement, including the Statements of Work, the Deliverables, any trade
secrets, data, documentation or other information relating to or used in the
Software or Deliverables, or any other information relating to the work

pursuant to Section 2.4 without Commerce One's prior written approval. In the
event Commerce One shall require access to technical information considered
confidential to NTT, Commerce One agrees to enter into a mutually acceptable
confidentiality agreement with NTT for the limited purpose of the required
disclosure. Confidential Information that is in written, graphic, machine
readable or other tangible form shall be marked "Confidential," "Proprietary" or
in some other manner to indicate its confidential nature. If Confidential
Information is disclosed orally, it shall be confirmed at the time of disclosure
as confidential and be reduced to written summary and delivered to the receiving
party within forty-five (45) days after disclosure and marked "Confidential,"
"Proprietary" or in some other manner to indicate its confidential nature. Each
party shall not use Confidential Information of the other party except as
authorized herein or otherwise authorized in writing, shall implement reasonable
procedures to prohibit the disclosure, unauthorized duplication, misuse or
removal of the other party's Confidential Information, shall not disclose such
Confidential Information to any third party, and shall only disclose the
Confidential Information to those of its directors, employees, subsidiaries and
advisors who need access to such information to exercise the rights and fulfill
the obligations set forth herein. Without limiting the foregoing, each of the
parties shall protect the Confidential Information using at least the same
procedures and degree of care that it uses to prevent the disclosure of its own
confidential information of like importance, but in no event less than

                                      -11-

reasonable care. Should any portion of the Confidential Information be
disclosed or used, the receiving party shall cooperate fully with the
disclosing party to enforce its proprietary rights.

     The parties understand, however, that any of the following information is
not subject to this confidentiality requirement:

     (1)  information which at the time of disclosure was or thereafter becomes
          in the public domain through no act or omission of the recipient;

     (2)  information which prior to disclosure was already in the recipient's
          possession either without limitation on disclosure to others or
          subsequently becoming free of such limitation;

     (3)  information obtained by the recipient from a third party having an
          independent right to disclose the information;

     (4)  information which is independently developed by the recipient without
          using the Confidential Information; or

     (5)  information that the receiving party is required to disclose by any
          court order or government action; provided that the receiving party
          gives the disclosing party at least 30 days' advance written notice to
          seek a protective order relating to any such disclosure and, provided,
          further, that the receiving party will only furnish the portion of the
          Confidential Information that it is required to disclose.

     12.  LIMITED WARRANTY; DISCLAIMER OF WARRANTIES

          12.1 LIMITED WARRANTY. Commerce One warrants to NTT that for a

refund the portion of License Fees attributable to such Software less a
reasonable amount for use based on straight line depreciation over a five (5)
year period. In case of the Service Fees, such refund shall be as determined
by the parties in good faith.

party's rights or remedies under this Agreement must be in writing to be
effective. Failure, neglect, or delay by a party to enforce the provisions of

construed in accordance with the laws of the State of California, without
regard to conflict of law principles or the 1980 UN Convention on Contracts

          14.10     ARBITRATION.

               (a)  Any dispute, controversy or claim arising out of or

                             (iii) Activities

The focus of Phase II is to develop the infrastructure and "go to market"
plans for NTT Japan and to enhance the Commerce One Commerce Chain Solution
for the Japanese marketplace.  The project team will be working very closely
with both the Commerce One implementation consultants and the Commerce One
product marketing and engineering teams.

The activities for Phase II begin in early May, 1999 to leverage the working
relationship that has started between the two companies.  The system that is
operational at NTT America will play a critical role in this phase by
providing both a referenceable site and a working solution to assist in the
functional design for the Japanese marketplace.


The Phase II activities are described below:

1.  PROJECT MANAGEMENT - The overall project management responsibility will
    reside with NTT, but Commerce One would provide management support at the
    Steering Committee level with representation by one of Commerce One's
    corporate executives and at the project team level with its account
    management/executive support.  Team leadership would also be NTT's
    responsibility with Commerce One product consultants supporting each
    team.  Monthly status reports would be required, as well as quality
    assurance monthly meetings.

    DELIVERABLES: Monthly Status Report
                  FINAL PHASE II DETAILED PROJECT PLAN

2.  MARKETING AND BUSINESS PLAN - The Marketing and Business Plan has three
    major components that have been identified to be included to support
    NTT's Electronic Commerce Services vision. This plan is expected to
    provide the initial framework and will be updated as NTT moves closer to
    executing against the vision.  Commerce One is expecting to provide
    consulting support to the development of this plan, leveraging its
    experience and market knowledge.

    -  The first component is the definition of the actual business goals.
       This includes the business vision for Japan, an initial analysis of a
       few short-term business opportunities that will offer proof points in
       Japan, and the revenue models for these opportunities with milestones.

    -  The second component is a clear definition of roles and
       responsibilities within NTT.  It is important to define product
       ownership issues, the required organizational structure to support the
       business model, and the estimated funding required to support the
       rollout of the solution.

    -  A third component is a more complete market analysis that will clearly
       define the three to five year revenue objectives.  This analysis will
       also be supported by the identification of the key suppliers and
       trading partners for the NTT Electronic Commerce Services Solution.


                                      4
<PAGE>

    Once the plan has been completed, Commerce One would welcome the
    opportunity to co-present the plan to NTT Japan as a further example of our
    working partnership.

3.  JAPANESE MARKETSITE -  Due to the significant long term revenue goals
    that will be generated through the Japanese MarketSite hosted by NTT, it
    is imperative that the right resources are available to address the
    planning, design, and implementation.  It is also imperative that this
    activity starts on time.  Commerce One will work closely with NTT during
    this major activity from definition through implementation and into
    production.

    -  THE PLANNING TASKS ARE EXPECTED TO AGAIN LEVERAGE COMMERCE ONE'S
       EXPERIENCE AND TOOLS.  AN EXAMPLE IS THE TASK ASSOCIATED WITH CONTENT
       MANAGEMENT.  NTT WILL BE EXPECTED TO WORK WITH THE COMMERCE ONE
       CONTENT MANAGEMENT GROUP TO UNDERSTAND ITS METHODOLOGIES AND TOOLS.
       THIS KNOWLEDGE TRANSFER WILL ENABLE THE NTT CONTENT TEAM TO BEGIN
       WORKING WITH ITS TARGETED SUPPLIERS TO ACQUIRE CONTENT, MAP IT TO THE
       PROPER CATEGORIES AND STRUCTURES, AND BEGIN TO PUBLISH IT IN THE
       REQUIRED FORMAT TO MAKE IT "TRANSACTIVE CONTENT."

    -  THIS APPROACH IS ALSO EXPECTED TO TAKE PLACE WITH THE SUPPLIER
       ADOPTION METHODOLOGY DEFINITION TASK.  NTT IS EXPECTED TO ADOPT THE
       METHODOLOGY THAT COMMERCE ONE HAS DEVELOPED FOR THE JAPANESE
       MARKETPLACE.  THIS WOULD INCLUDE MARKETING PROGRAMS, COMMUNICATION AND
       INCENTIVE PROGRAMS.

    -  ANOTHER AREA IS SUPPLIER INTEGRATION.  NTT WOULD DEVELOP THEIR
       TECHNICAL STRATEGY TO FULLY INTEGRATE KEY SUPPLIERS OR TO OFFER THE
       WEB-BASED SUPPLIER MANAGEMENT SOLUTION TO SUPPLIERS.  THE TECHNICAL
       STRATEGY WILL IMPACT THE TECHNICAL PLATFORM DESIGNS AND IMPLEMENTATION
       PLANS.

    -  A KEY COMPONENT OF A COMPLETE TECHNICAL PLAN WILL BE THE EXPECTED
       BENCHMARKS AND PERFORMANCE CRITERIA THAT NTT WANTS TO PUT IN PLACE TO
       MEASURE THEIR SERVICE STANDARDS.  THE OUTPUT WILL BECOME INPUT INTO
       THE OVERALL PROJECT FUNDING.

    Once the planning is complete, the NTT project team can begin the
    implementation of its Japanese MarketSite.  This process will need to be
    coordinated with Commerce One's MarketSite product management team to
    ensure that the installation in Japan starts with the latest release.
    The implementation process will include the establishment of the
    environment, the delivery of the software and testing, the loading of the
    adopted suppliers' content, and the training of the support staff.

4.  JAPANESE LOCALIZATION - This activity will start very early in the
    project with the initial focus on completing a detailed design document
    that will be turned over to the NTT translator. The design will include
    the user interface, documentation, online help, error messages, test
    scenarios, and training materials.  After review of the above, the
    project team would then focus on defining any unique functional
    requirements, changes to reflect the Japanese operating system and
    database requirements, and changes to the Commerce One support
    tools/products (e.g., catalog administration, SupplyOrder).

    The design would then be followed by the development and testing
    activities for each of the above sections.   NTT's involvement in these
    activities will provide the required detailed product knowledge that will
    allow NTT to rapidly become self-sufficient.  Commerce One's primary role
    would be in assisting in the design activities around functional
    enhancements.

5.  JAPANESE BUYSITE - This is the activity that will install Commerce One's
    BuySite product at NTT Japan connected to NTT's MarketSite to conduct
    electronic commerce between a selected internal department


                                      5
<PAGE>

    and a minimal set of Japanese suppliers.  The key contingencies are the
    translation efforts, conversion to the Japanese operation system and
    database requirements, and having a fully functioning MarketSite.  With
    these tasks in place the actual implementation effort will be very
    similar to the one that took place at NTT America.  It is expected that
    the NTT project team will be in a position to manage and perform the
    majority of the implementation tasks with Commerce One providing product
    consulting and project oversight.

    Unlike the implementation of the NTT America BuySite, this implementation
    will require the project team to actively engage in the supplier adoption
    and content management activities.  The plan is based upon the initial
    Japanese suppliers for the internal BuySite to also be key suppliers that
    will be a part of the initial NTT Hosted BuySite rollout.  NTT will
    utilize the supplier adoption programs developed by Commerce One as the
    basis for its own programs.  These will be adapted for the Japanese
    marketplace and NTT will take the lead on bringing the identified
    suppliers on board.  NTT and Commerce One will work together on utilizing
    the content management tools and building the content processes to
    convert the supplier catalog information into transactive content format.

    One of the tasks under this activity that will require Commerce One
    participation will be integration analysis and design to NTT's selected
    procurement/financial system (e.g., SAP, Baan).  The goal is to first
    implement the BuySite product in a stand-alone environment as part of
    Phase II and then develop and implement the integration processes as part
    of the early part of Phase III.  This is done to ensure that NTT can
    begin to realize their return on investment as early as possible.  The
    development and implementation effort will not require Commerce One's
    participation.

    Commerce One has included in its resource plans onsite "help desk"
    assistance for the first two months of production and onsite technical
    support for the first two months of production.  These resources will be
    supported by Commerce One's Customer Service Center that delivers 7 by 24
    hour support for level two and level three problems.

6.  HOSTED BUYSITE (DESIGN AND DEVELOPMENT) -- Commerce One will be
    responsible for the design and development of its Hosted BuySite product.
    This effort will be driven by solid engineering methodology, which will
    include organizational modeling, focus group input, and customer design
    review sessions.  NTT is welcomed to actively participate in the Commerce
    One Design Program.  This group meets on a regular basis to receive
    detailed work through from product development team and the group
    receives design materials for review and input.  A couple of the areas
    that NTT may be able to offer valuable insight in the design: security,
    system management, reporting and supplier ERP integration.  At a minimum,
    as part of the product consulting support, Commerce One will keep the NTT
    project team well informed on the design and development timelines and
    will share design documentation to ensure that any unique NTT
    requirements can be analyzed against the expected delivered product.
    Hosted BuySite functions will be integrated into BuySite 6.0.

7.  HOSTED BUYSITE (IMPLEMENTATION) - One of the advantages of the strategy
    that has been jointly developed is NTT will have become self-sufficient
    with the supplier adoption and content management activities through
    their efforts in the implementation of the NTT BuySite solution.

    Commerce One and  NTT will have worked together to put in place the
    robust content management processes that simplifies the process for
    suppliers to deliver content updates that contain items and


                                      6
<PAGE>

    content that is relevant to NTT internal use as well as content for the
    commercial use in the Hosted NTT Solution.  The Commerce One methodology
    includes a set of administrative tools that allow NTT to create a
    "catalog profile" for each supplier and a "catalog profile" for the
    individual groups of users. This process is greatly simplified if the
    Supplier maintains their content within MarketSite, as the tools are also
    available for the suppliers to establish "customer profiles" to provide a
    first filtering step before the new content is pulled to NTT.  These
    integrated suppliers are also able to provide on-going updates on price
    and availability as their products are being checked prior to an order or
    as their products are being ordered.

    The Supplier Adoption program focuses on educating NTT suppliers on the
    value of electronic procurement and how they can participate with NTT. As
    part of this program, each strategic supplier's ability to adopt the NTT
    Electronic Commerce Services Solution is evaluated and rated to confirm
    their ability to be a part of the NTT implementation.  They are
    prioritized and individual plans are prepared and agreed to.

8.  SUPPLIER ADOPTION AND CONTENT MANAGEMENT PROGRAMS - The Supplier Adoption
    and Content Management program focuses on building organizations and
    processes to support these efforts and also to assist educating NTT
    suppliers on the value of electronic procurement and how they can
    participate with NTT. As part of this program, each strategic
    suppliers's ability to adopt the NTT Electronic Commerce Services
    Solution is evaluated and rated to confirm their ability to be a part of
    the NTT implementation. They are prioritized and individual plans are
    prepared and agreed to.

1.       Commerce One Deliverables


In consideration of payment of charges, royalties and fees described in clause
2, Commerce One shall deliver the following licences, services and deliverables.

- --------------------------------------------------------------------------------
1.1 MARKETSITE LICENCE
- --------------------------------------------------------------------------------


(a)      For the licence fee and royalties set out in clause 2(a), Commerce
         One hereby grants BT a perpetual, transferable license to install
         the MarketSite Software anywhere in the UK. BT may use the
         MarketSite Software to offer a commercial service to any customer
         anywhere in the world except BT undertakes that during the Initial
         Period it will not actively market (which for the avoidance of doubt
         does not prevent fulfillment of existing or passively acquired
         supplier commitments or responding to requests from suppliers with a
         principal place of business in the areas referred to below or
         elsewhere or fulfilling access requests in these areas) its
         MarketSite Services to suppliers whose principal place of business is
         in Japan, North America, Latin America or South Africa; this
         limitation shall only apply to the extent that Commerce One has
         contractual exclusivity commitments with another party (Commerce One
         shall use all reasonable endeavours to ensure that such commitments
         will give BT reciprocal rights in respect of passively acquired
         sales to those detailed above). For the avoidance of doubt this
         Licence is a Commercial Service Licence as referred to in clause
         5.2.2 of the Trading Agreement.

(b)      Subject to clause 1.1 (c) Commerce One undertakes that it will not
         itself, and will not grant any license to a third party in respect
         of the MarketSite Software or any software with equivalent
         functionality which permits that third party during the Initial
         Period to, install in the UK or to actively market its MarketSite
         Services to suppliers (which for the avoidance of doubt does not
         prevent fulfillment of existing or passively acquired supplier
         commitments or responding to requests from suppliers with a
         principal place of business in the UK or access requests in the UK)
         whose principal place of business is in the UK or itself so actively
         market during the Initial Period Provided that for the avoidance of
         doubt this restriction does not prevent access being allowed by
         another MarketSite operator with MarketSite software installed
         outside the UK to a supplier whose principal place of business in
         the UK if it is requested by a customer of that MarketSite operator
         where such access is not then available through connections between
         BT and that MarketSite operator or the customer does not wish to
         access it in that way, Commerce One agrees to allow such other
         MarketSite operators the same freedom as in this proviso.

(c)      If in any quarter as specified below BT does not sell (meaning entering
         into a legally binding agreement and receiving the initial payment
         for) the minimum number of milestone extranet access licenses to its
         MarketSite Services specified in the table below (subject to any
         adjustment in accordance with (i) below) for that quarter ("deficit
         quarter"). Commerce One may, by notice to BT given within seven (7)
         Business Days following the end of that quarter, terminate its
         undertaking in clause 1.1 (b) and the obligations under
         Clause 1.1(d)(i) and (ii).

         Provided that (but only if the provisions of this proviso have not been
         implemented in both the preceding two quarters) Commerce One's notice
         given as above shall cease to be of effect if within the ten (10)
         Business Days referred to above either

         (i)  BT agrees that the minimum number of extranet access licences for
              the then current quarter shall be increased by the amount of the
              shortfall in the deficit quarter or

         (ii) BT undertakes to Commerce One within such ten (10) Business Days
              to pay to Commerce One a sum equal to 100% of the average extranet
              access licence fees charged by BT in the quarter (if any) which

- --------------------------------------------------------------------------------

              preceded the deficit quarter multiplied by the shortfall in number
              in the deficit quarter.

         The following is the schedule of milestone extranet access licences to
         BT's MarketSite Services during the Initial Period:

                    30 June 2000                                               [*]
</TABLE>

         References to extranet access licences and fees for them include for
         the above purpose licences or subscriptions howsoever designated and
         fees for them.

         BT shall notify Commerce One in writing of the relevant sales in each
         of the above quarters within three (3) Business Days of the end of that
         quarter failing which it shall be conclusively presumed for the
         purposes of determining whether Commerce One's right under this (c) is
         exercisable that there were no such sales.

(d)      (i)  BT undertakes that BT e-Business will only promote the
              MarketSite Service using MarketSite for business-to-business
              electronic procurement of commoditised indirect goods and
              services during the Initial Period. Should BT breach this
              undertaking Commerce One may by notice in writing to BT
              terminate its undertakings in Clause 1.1(b) and the obligations
              under clauses 1.1.(d)(i) and (ii) provided that this shall not
              prevent promotion of single supplier catalogues promoted by
              Infobank or ICAT or GEM's retail direct good trading. For the
              avoidance of doubt this obligation shall not apply to BT other
              than BT's unit or units e-Business unit or its successor.

         (ii) Commerce One undertakes that it will only promote to suppliers or
              customers in the UK BT's MarketSite Service for
              business-to-business electronic procurement of commoditised
              indirect goods and services during the Initial Period.

(e)      Commerce One undertakes that before 30 September 1999 it will publish
         open APIs and provide MarketSite integration to third party purchasing
         applications.

(f)      For the avoidance of doubt no licence is granted to Commerce One in
         respect of content, pricing and transactional information that may be
         derived from BT's use of the MarketSite Software.



- --------------------------------------------------------------------------------

The parties agree that all major and minor upgrades and new releases of the
MarketSite product shall be offered to BT at no charge under the current
Maintenance and Support Agreement and will be reflected in the standard
Maintenance and Support arrangements. The parties further agree that additional
value-added services which Commerce One provides to BT which have either (1) an
identifiable incremental revenue stream, (2) are sourced from third parties and
carry a royalty obligation by Commerce One to the outside vendor, or (3) can
reasonably be considered to have new functionality that is bundled and sold by
Commerce One as an add-on product to other customers, shall be considered new
products, and Commerce One shall be authorized to price separately from the
initial MarketSite license fee paid by BT.

- --------------------------------------------------------------------------------

- --------------------------------------------------------------------------------

         b)       Commerce One agrees that any additional services required by
                  BT shall be billed at Commerce One's Professional Services
                  Rates from time to time, the current rates being as set forth
                  in Appendix 2 to this Licence (subject to BT placing an Order
                  for such services from time to time) provided that increases
                  in the first 5 years of this Agreement shall not exceed
                  increases in the US Consumer Price Index after the date of
                  this Licence and no increase shall take effect before the
                  expiry of 12 months from the date of this Licence.

         c)       BT will provide supplier content management as part of the
                  Market Site service, with the amount and timing of the content
                  to be adopted to be subject to agreement between BT and its
                  customers. BT may procure additional services from Commerce
                  One to deliver service to its customers at charges to be
                  mutually agreed on a case by case basis.

2.    GENERAL

      2.1     If any aspect of the Trading Agreement is found to be invalid,
              illegal or unenforceable this shall not affect the validity of any
              part of the Trading Agreement. In such case Trading Agreement
              shall be construed and enforced as if it did not contain such
              provision. The parties shall negotiate in good faith to modify
              and, or replace such provision with one that is valid and legally
              enforceable. If the parties cannot reach agreement on a new
              provision which places the parties in a position similar to the
              commercial position which would have prevailed prior to the
              modification or replacement being required, either party may, in
              its sole discretion, withdraw from the Agreement.

      2.2     The headings to the Trading Agreement provisions are for reference
              only and shall not affect their interpretation.

      2.3     No delay, neglect or forbearance by either party in enforcing any
              provision of the Trading Agreement shall be deemed to be a waiver
              of or in any way prejudice any rights of that party.

      2.4     No waiver by either party shall be effective unless made in
              writing or constitute a waiver of rights in relation to any
              subsequent breach of the Trading Agreement.

      2.5     The Trading Agreement and those terms explicitly included in any
              Order and referenced on the Official Order cover sheet thereto
              govern the relationship between the parties in relation to the
              subject matter of this Agreement to the exclusion of any other
              terms and conditions, unless such other terms are agreed in
              writing between BT


<PAGE>

              and Commerce One. Should any conflict exist between the terms of
              the Trading Agreement and an Order then the precedence provisions
              of Section 3.4 of this Agreement shall apply.

      2.6     The Trading Agreement is governed by English law and the parties
              hereby submit to the jurisdiction of the English Courts. The
              parties hereto agree that the Convention on International Sale of
              Goods shall not apply to this Agreement.

      2.7     Other than as set out herein, neither party shall, nor in any way
              represent itself as, an agent of the other and shall have no
              authority to enter into any obligation on behalf of the other or
              to bind the other in any way.

      2.8.1   Notices required under the Trading Agreement to be given in
              writing shall be delivered by hand or by post or by facsimile
              transmission. Notices shall be deemed to be given upon receipt
              except that notices sent by pre-paid recorded delivery post in a
              correctly addressed envelope shall be deemed to be given within 48
              hours (excluding Sundays and public holidays) of posting, and
              notices sent by facsimile transmission shall be deemed to be given
              upon transmission.

      2.8.2   Notices are to be given to BT and/or the Ordering Entity (where
              appropriate). Where notices are to be given to BT they shall be
              sent to the address below. Where notices are to be given to the

<PAGE>

      2.9     Without prejudice to any prior obligations of confidentiality it
              may have, either party shall ensure that no publicity relating to
              the Trading Agreement or any Order shall take place without the
              prior written agreement of either BT or C1 (for the Agreement) or
              the appropriate Ordering Entity (for any Order), which consent
              shall not be unreasonably withheld.[this change makes the
              agreement consistent with the Confidentiality Section - otherwise
              these provisions are in conflict].


      2.10    The provisions of the following Sections of the Trading Agreement
              set out below and any Sections relating thereto set out in any
              Order shall survive the termination or expiry of the Trading
              Agreement and/or any Order:

              Section 5 - Intellectual Property and Licenses
              Section 7.3 - Year 2000 Warranty
              Section 17 - Confidentiality
              Section 19 - Intellectual Property Indemnity
              Section 26 - Indemnity - General
              Section 27 - Limitation of Liability

      2.11    Neither party shall be liable to the other for its failure or
              delay in the performance of a required obligation if such failure
              or delay is caused by strike, riot, fire, flood, natural disaster
              or other similar cause beyond either party's control provided,
              however, that either party gives prompt written notice of such
              condition and resumes the performance of its obligations as soon
              as possible.


3.    DESCRIPTION OF WORK

      3.1     Commerce One shall accept and fulfill all Orders placed in
              accordance with the Trading Agreement where such Orders are for
              the supply of Programs, products and services listed in Schedule 2
              (Pricing), provided that Commerce One agrees and that it is
              commercially reasonable for Commerce One to do so.

      3.2     Commerce One shall accept Special Commissioning Orders (as
              provided for under Section 5) where Commerce One has submitted a
              valid quotation approved by an authorized signatory of Commerce
              One.

      3.3     The Work shall accord with any specifications agreed by both
              parties and referred to in the Order accepted by Commerce One from
              the Ordering Entity. Commerce One shall


<PAGE>

              provide reasonable assistance necessary to carry out the
              installation, commissioning and testing.

      3.4     The Work shall be performed in accordance with the Trading
              Agreement and with the provisions of such Order(s) that an
              Ordering Entity in its sole discretion may place in accordance
              with the Condition headed "Order Procedure" of this Schedule 1.
              Should the terms and conditions of any Order conflict with or vary
              from those of the Trading Agreement then the Trading Agreement
              shall take precedence; however variations that are clearly and
              explicitly set out or referenced in the Variation to Trading
              Agreement section of the Official Order Cover Sheet shall take
              overall precedence over the terms set forth in this Trading
              Agreement.

      3.5     The Trading Agreement is not in itself an order for Work and no
              Ordering Entity shall be under any obligation to order Work. It is
              a framework agreement against which the Ordering Entity may order
              Work. Notwithstanding the foregoing, any Ordering Entity shall
              cooperate with Commerce One in the provision of information,
              hardware, software or other materials or resources, at no charge
              to Commerce One, as more fully set out in each Order.

      3.6     Neither BT nor any other member of the Alliance shall be liable
              for, or in relation to, any Order not placed by it. Further,
              neither BT, nor any other Ordering Entity shall be liable for any
              act or omission of any other Ordering Entity whether in relation
              to the Trading Agreement, any Order or otherwise. Any Ordering
              Entities placing orders under the Trading Agreement are separately
              and individually liable for anything pertaining to any such Order.
              Notwithstanding the foregoing, Commerce One's performance (as
              described in Section 15) shall be dependent upon the timely and
              accurate receipt of such cooperation by the Ordering Entity.

      3.7     No breach by any Ordering Entity other than BT in relation to any
              Order shall affect the validity or continuation of this Trading
              Agreement.

4.    PRICES AND LEADTIMES

      4.1 Commerce One agrees that the prices of Work payable by any Ordering
Entity:

           (a) shall be no less favourable than those payable within the
               prior six (6) months period of time by any other Ordering
               Entity or by any third party for similar supplies; and

           (b) without prejudice to sub-paragraph (a) above, shall, where
               reductions in such prices in relation to any individual
               Ordering Entity are volume sensitive, be determined as though
               the volumes of similar supplies committed to every other
               Ordering Entity had been aggregated with such individual
               commitment.

           (c) For the avoidance of doubt, if Commerce One offers Work at a
               lower price than that offered to an Ordering Entity within six
               (6) months following the Order, then Commerce One shall be
               obligated to offer the Ordering Entity the more favourable
               price on a going-forward basis.


<PAGE>

      4.2     Commerce One shall if requested by the Ordering Entity determine
              whether lead times can be improved to meet specific project
              timescales and advise the Ordering Entity if this can be achieved
              and whether there are any additional costs which would require a
              change order to be implemented to achieve such improved lead time.

      4.3     Commerce One shall acknowledge receipt of an Order in writing
              within one business day from receipt.


5.       INTELLECTUAL PROPERTY AND LICENSES

      5.1     Intellectual Property Rights in the Programs and Documentation
              belong to Commerce One or its licensors. The Ordering Entity shall
              ensure that all copyright notices and trade marks of Commerce One
              and/or its licensors are retained in all copies of the Programs,
              Documentation possessed by the Ordering Entity and shall be

              Ordering Entity, Commerce One hereby grants the Ordering Entity a
              worldwide (subject to such Variations to Trading Agreement as are
              prominently set forth on the Official Order Cover Sheet of the
              Order), perpetual, transferable (provided that such transferee is
              a member of the Alliance) licence, subject to payment of the
              licence fees set out in any Order, to:

              5.2.1      Use the Programs and Documentation for the Ordering
                         Entity's own internal business purposes. The Ordering
                         Entity may make a reasonable number of copies of the
                         Programs and/or Documentation to the extent required
                         for internal training and processes, and

              5.2.2      Where the Official Order Cover Sheet specifies a
                         Commercial Service License to use the Programs and
                         Documentation in order to offer commercial service to
                         End Users pursuant to this Agreement. The Ordering
                         Entity may make copies of the Programs and/or
                         Documentation to the extent required for internal
                         training and processes and as far as is necessary in
                         order to exercise its right to sub-license the Programs
                         and Documentation to End Users under Section 5.2.3.,
                         and

              5.2.3      Sub-license those elements of the Programs listed in
                         the Order as sublicensable and relevant Program
                         Documentation as listed in the Order to End Users.


<PAGE>

      5.3     The Ordering Entity shall not use the Programs or Documentation
              for any purpose other than as specified in this Section 5 and
              shall not sell or otherwise make available the Programs or
              Documentation nor any information relating thereto to third
              parties who are not End Users.

      5.4     The Ordering Entity shall not undertake or permit the
              modification, reverse engineering, disassembly or decompilation of
              the Programs except to the extent permitted at law.
              Notwithstanding the foregoing, the Ordering Entity shall notify
              Commerce One prior to undertaking any reverse engineering so as to
              give Commerce One the opportunity to provide the required
              information to the Ordering Entity.

      5.5     The Ordering Entity agrees that it shall make each End User aware
              that the Documentation and Programs, are Confidential Information
              of Commerce One and/or its licensors, and may not be disclosed to
              any third party unless so required by law or with the prior
              written consent of Commerce One.

      5.6     All Ordering Entity Background Information and any copies thereof
              and all Intellectual Property Rights therein shall remain the
              property of the Ordering Entity. Commerce One shall return the
              Ordering Entity Background Information to the relevant Ordering
              Entity upon expiry or termination of the Trading Agreement or
              relevant Order, or earlier upon request by the Ordering Entity.

      5.7     Except as expressly set out in the Trading Agreement or any Order
              no assignment of or license under any Intellectual Property Right
              owned or controlled by the Ordering Entity is granted by the
              Trading Agreement or by any Order.

      5.8     From time to time an Ordering Entity may commission Foreground
              Information from Commerce One via a Special Commisssioning Order.
              Commerce One hereby grants to the Ordering Entity a perpetual

              Variation to Trading Agreement section on the Official Order Cover
              Sheet), transferable (only to members of the Alliance) licence to
              use copy and sublicense the Foreground information for its
              business purposes. This licence may be subject to the payment of
              license fees and or royalties to Commerce One as expressly set out
              in the Special Commissioning Order. For the avoidance of doubt,
              Commerce One shall own all Foreground information unless otherwise

              license on the same terms as the Programs licensed in this Trading
              Agreement in respect of any Foreground Information developed by
              Commerce One under any Special Commissioning Order for any
              Ordering Entity () on the terms and conditions as set out in the
              Special Commissioning Order or the applicable Order.

              Programs are set out in Appendix A, the Support and Maintenance
              Agreement. As part of any Order, the Ordering Entity may execute a
              Support and Maintenance Agreement with Commerce One in the form
              set out in Appendix A to this Agreement. Commerce One may not
              refuse to enter into such an Agreement if requested subject to

              applicable Order.

              Commerce One and any not so deducted may be recovered by the
              Ordering Entity from Commerce One as a debt.

              under this Condition shall not affect any of the Ordering Entity's
              or BT's rights under the Condition headed "Termination" provided

                         performance against any standard specified and agreed
                         by Commerce One and the Ordering Entity in any Order

                         Commerce One under the Trading Agreement.

              15.2.3     All sums retained in respect of Commerce One's failure
                         to achieve any Order Standard shall be released, in
                         addition to all other amounts owed to Commerce One
                         under the Order, to Commerce One following the first
                         month there after in which Commerce One's achieved
                         performance has subsequently met or exceeds that Order
                         Standard.

              15.2.4     In any event the Ordering Entity shall not pay any
                         invoice unless the Order Standard statistics have been
                         submitted by Commerce One within 7 days of the relevant
                         invoice date.

              without prejudice to any other rights or remedies under the
              Trading Agreement.

      15.4    Delivery and Acceptance. Upon delivery of Work performed by
              Commerce One to the Ordering Entity by Commerce One, the Order
              Entity shall evaluate the Work for conformity with the
              specifications set forth in the Order. Within thirty (30) working

                         reconstruction or amalgamation);

      16.5    The Ordering Entity may at any time, without prejudice to any
              other rights and remedies it may have, terminate Orders forthwith
              on forty five (45) days written notice. Where the Ordering Entity
              terminates Orders under this Condition and does not have any other
              right to terminate as set forth above, the Ordering Entity shall
              pay Commerce One such amounts as may be necessary to cover its
              reasonable costs and outstanding and unavoidable commitments
              necessarily incurred solely in performing the Orders in relation
              to the Work ordered by the Ordering Entity before the date of
              termination and for which payment has not at that date become due
              from the Ordering Entity ("the Applicable Work"). However, the
              Ordering Entity shall not pay for any such costs or commitments
              that the Commerce One is able to mitigate and shall only pay costs
              and commitments that the Ordering Entity has validated to its
              satisfaction. For the avoidance of doubt, resource commitments
              made by Commerce One to fulfill Orders shall count as compensable
              expenses provided that Commerce One can document to the reasonable
              satisfaction of the Ordering Entity such resource commitment
              expenses.

              Notwithstanding the above, the Ordering Entity's total liability
              under this Section 16.5 shall not in any circumstances exceed the
              price that would have been payable by the Ordering Entity for the
              Applicable Work if the Order had not been terminated (which price
              shall include the costs of such resource commitments referenced
              above). Apart from any payments to be made as set out in this
              Section 16.5, and subject to Section 16.6, the Ordering Entity
              shall have no liability to make any payments to Commerce One in
              relation to the Order following its termination by the Ordering
              Entity in accordance with its rights referred to above.


<PAGE>

      16.6    In the event that the Agreement or an Order is terminated for any
              reason whatsoever, any rights and obligations of any party hereto
              which may have accrued prior to the date of such termination shall
              not be affected. Furthermore, Commerce One shall complete all
              other Orders existing at the time of termination of the Agreement,
              including all support obligations as if the Agreement had not been
              terminated.

      16.7    Termination of the Agreement or Order shall be without prejudice
              to any provision intended to operate thereafter.


17.      CONFIDENTIALITY

      17.1    Subject to the Condition headed `Intellectual Property", either
              party receiving Information ("the Recipient") from the other shall
              not without the other's prior written consent use such Information
              except for Contract purposes or disclose such Information to any
              person other than BT people or Contract Personnel who have a need
              to know. The Recipient shall return documentation containing such
              Information to the other party when no longer required for such
              purposes.

      17.2. Section 17.1 shall not apply to Information that is:

              a)     published except by a breach of the Contract; or
              b)     lawfully known to the Recipient at the time of disclosure
                     and is not subject to any obligations of confidentiality;

              d)     replicated by development independently carried out by or
                     for the Recipient by an employee or other person without
                     access to or knowledge of the Information.

      17.3.   Neither Commerce One or BT shall publicise the Agreement or any
              Order without the other's prior written consent and shall ensure
              that any subcontractor is bound by similar confidentiality terms
              to those in this Condition.

      17.4.   Without prejudice to any prior obligations of confidentiality it
              may have, where Commerce One or Contract Personnel have access to
              BT's computer systems or to Information relating to BT's customers
              or subject to the Data Protection Acts 1984/1998 ("DPA"), Commerce
              One shall:


<PAGE>

              a)     comply (and ensure that all relevant Contract Personnel
                     comply) with all relevant provisions of any BT Codes of
                     Practice (mutatis mutandis) appended to the Contract or
                     notified to Commerce One from time to time, the Computer
                     Misuse Act 1990 and the DPA; and

              b)     ensure all such Contract Personnel first sign and deliver
                     to BT a confidentiality agreement in the form appended to
                     the Agreement in Appendix D, or in such form as BT shall
                     reasonably require; and

              c)     ensure such Information is not disclosed to or accessed by
                     Contract Personnel not directly employed by Commerce One
                     without BT's prior written consent; and

              d)     keep (and ensure all relevant Contract Personnel keep) such
                     Information secure, act only on BT's instructions with
                     respect to it, and comply with such further reasonable
                     requirements from time to time of BT for the security of
                     it; and

              e)     not export such Information outside the European Union
                     without BT's prior written consent; and

              f)     allow (and ensure that all relevant Contract Personnel
                     allow) BT or its authorised representatives such access to
                     premises, systems and records containing such Information
                     as is reasonably necessary to assess Commerce One's

19.      INTELLECTUAL PROPERTY INDEMNITY

      19.1    Commerce One shall fully indemnify the Ordering Entity against all
              actions, claims, proceedings, damages, costs, and expenses arising
              from any infringement or alleged infringement of any patent,
              copyright or trade secret arising from the use by the Ordering
              Entity of the Programs, the Program Documentation or other
              Information supplied by Commerce One pursuant to this Agreement.
              Notwithstanding the foregoing, Commerce One shall have no
              obligation to indemnify under this Section 19 if such infringement
              claim results from corrections/modifications not provided by
              Commerce One, failure to install updates, combinations of the
              Programs software with any software not provided by Commerce One,
              or specific customization of the Program software at the request
              of BT (which shall be defined as the addition or inclusion of any
              specific functionality requested by BT) or any Alliance members.


<PAGE>

      19.2    BT and/or the Ordering Entity shall notify Commerce One, and
              Commerce One shall notify BT, promptly in writing of any
              infringement or alleged infringement referred to in Section 19.1.

      19.3    In the event of any such infringement or alleged infringement as
              set out in Section 19.1, Commerce One shall at its own expense
              and, provided Commerce One exercises reasonable judgement, its own
              option:

              19.3.1     Substitute a substantially equivalent non-infringing
                         product allowing the Ordering Entity unrestricted use
                         of the infringing Programs or Documentation, and to
                         exercise its other rights granted it under the trading
                         Agreement and relevant Order in respect of such
                         Programs or Documentation; or

              19.3.2     Modify or replace the Programs or Documentation , so as
                         to meet the existing functional specification and avoid
                         the claim of infringement and any injunction or court
                         order; or

              19.3.3     Negotiate for settlement of or defend the claim, and
                         hold the Ordering Entity harmless from any judgement,
                         order or settlement. Commerce One shall endeavour to
                         conduct such negotiations and litigation in a timely
                         manner, provided that Commerce One shall have sole
                         central of the defense, including settlement.

              Unless otherwise agreed in writing Commerce One shall conduct all
              negotiations and litigation in relation to any such infringement
              or alleged infringement and be responsible for all costs and
              expenses incurred. The Ordering Entity shall afford all reasonable
              assistance in contesting such allegations but if Commerce One
              fails to conduct such negotiations or litigation within a
              reasonable time, the Ordering Entity may request to conduct of the
              same and in such instance Commerce One shall fully reimburse the
              Ordering Entity for all resultant costs.

      21.1    All Ordering Entity Items shall remain the property of the
              Ordering Entity. Commerce One shall return them to the Ordering
              Entity upon completion or termination of the Trading Agreement or
              relevant Order, or earlier reasonable request by the Ordering
              Entity. Commerce One shall keep the Ordering Entity Items, and
              (before their delivery to Ordering Entity) any items or things
              that are or have become the Ordering Entity's property ("Ordering
              Entity property"), in safe custody and good condition, set aside
              and clearly marked as Ordering Entity property. Commerce One shall
              be fully liable for any loss of or damage to Ordering Entity Items
              or Ordering Entity property.

      21.2    Upon receipt of the Ordering Entity Items, Commerce One shall
              satisfy itself that they are not defective or deficient for the
              purpose for which they are being provided, and within 14 days of
              receipt shall notify the Ordering Entity of any defects or
              deficiencies.

      21.3    Commerce One shall not, without the prior written consent of the
              Ordering Entity, use Ordering Entity Items for any purpose other
              than is necessary for the performance of the Trading Agreement, or
              allow any other party to use, take possession of, or have any
              rights or lien over Ordering Entity Items or Ordering Entity
              property.

      21.4    Without limiting the generality of Commerce One's obligations,
              Commerce One shall not have, and shall ensure that third parties
              shall not have, a lien on the Ordering Entity Items or Ordering
              Entity property for any sum due. Commerce One shall take all
              reasonable steps to ensure the title of the Ordering Entity and
              the exclusion of such lien are brought to the notice of all
              personnel dealing with any Ordering Entity Items or Ordering
              Entity property.

      21.5    In the event of any threatened seizure of any Ordering Entity
              Items or Ordering Entity property or in the event of Commerce One
              (or any personnel or Subsidiaries of Commerce One in possession of
              such Ordering Entity Items or property) going into receivership,
              administration or liquidation (or the equivalent of any of these)
              Commerce One shall:

              a)     Notify BT and the Ordering Entity immediately; and,

              b)     Draw to the attention of the relevant official that
                     Ordering Entity Items and Ordering Entity property are the
                     property of the Ordering Entity and do not form part of
                     Commerce One's assets; and,


<PAGE>

              c)     Allow BT and the Ordering Entity to enter Commerce One's
                     premises or those of any Subcontractor where Ordering
                     Entity Items or Ordering Entity property are stored and
                     take possession of them.


22.   ASSIGNMENT AND SUBCONTRACTING

      22.1    Commerce One shall be wholly responsible for the performance of
              the Work and the actions and omissions of all Subcontractors for

                         Agreement; or

              22.2.2     Assign or sub-contract part of the Trading Agreement
                         except as is customary in the trade; or

              22.2.3     Assign or sub-contract any Order in whole or in part
                         without the others permission in writing, provided,
                         however that, notwithstanding the foregoing, Commerce
                         One shall be able to assign this Trading Agreement to
                         an entity acquiring all, or substantially all, of its
                         assets or capital stock, provided that such entity is
                         not a competitor of BT or any of its majority owned
                         subsidiaries, in which case Commerce One shall be
                         required to receive BT's consent to such assignment. In
                         addition, Commerce One shall be able to use
                         subcontractors to complete any Work under this
                         Agreement or any Order.

      Information, within a reasonable time of receipt.


24.   PROTECTION OF DOCUMENTS AND PROGRAMS

      24.1    Both parties shall take suitable precautions to protect
              documentation and Programs [and Foreground Information] generated
              or required for the Trading Agreement or Order against loss of any
              kind. Upon the release of any Programs or Documentation


<PAGE>

              update a set of the latest Programs and documentation shall be
              stored by Commerce One in a safe location remote from Commerce
              One's normal work premises.

      24.2    Commerce One shall, if required by the Ordering Entity, enter an
              agreement with a neutral third party, acceptable to the Ordering
              Entity, to lodge with the third party copies of such Programs
              including source code and update them as necessary for release to
              the Ordering Entity in the event that Commerce One becomes
              unwilling or unable to support such Programs. Each party shall be
              responsible for its respective costs. Should the parties be unable
              to agree a mutually acceptable third party the services of Escrow
              International, UK shall be employed as a default option.

      24.3    In the event of either party being required to dispose of any
              Programs media during the course of any Work to be carried out
              under this Agreement he shall ensure that all such disposals are
              effected so as to give absolute protection to any of the other
              parties Information contained therein and to prevent any data
              falling into the hands of any third party.


25.   TITLE AND RISK

      25.1    Without prejudice to the Ordering Entity's right to reject under
              the Agreement or Order, the title in the Work shall pass to the
              Ordering Entity upon the earlier of delivery or Acceptance or the
              passing of risk or payment (including any part payment).

      25.2    Without prejudice to the Ordering Entity's right to reject under
              the Agreement or Order, risk shall pass from Commerce One to the
              Ordering Entity upon the later of, Acceptance, delivery or
              payment.

                           Order; provided that this does not apply to any
                           liability arising from defects in the Programs,

                                   APPENDIX D

         BT CODE OF PRACTICE ON THE DISCLOSURE OF CUSTOMER INFORMATION.


    BT Code of Practice on the Disclosure of Customer Information by BT
Supplemental Services Business.

INTRODUCTION

1.    British Telecommunications plc (BT) operates under a licence granted by
the Secretary of State for Trade and Industry under Section 7 of the
Telecommunications Act 1984 (the Licence).

2.    Conditions 38 and 38A of the Licence oblige BT to produce Codes of
Practice for use by those of its employees engaged in the Systems Business and
those of its employees engaged in the Supplemental Services Business
respectively. This Code is in relation to the Supplemental Services Business and
is intended to protect information about a customer acquired in the course of
the Supplemental Services Business so as to prevent the use of such information
to obtain an unfair advantage. For example, information that a customer has
contracted for value added services or data services should not be passed
without the customer's consent outside of the Supplemental Services Business to
help create a further selling opportunity for apparatus or systems. A separate
Code of Practice has been issued in respect of the Systems Business.

3.    The Code, which has been agreed by the Director General of
Telecommunications, is without prejudice to any other legal obligations of BT
towards its customers.

4.    BT has an obligation under Condition 38A to take all reasonable steps to
ensure that the terms of the Code are followed by employees in the Supplemental
Services Business. All other BT employees must co-operate with those in the
Supplemental Services Business to ensure that the Code is respected.
Instructions for BT employees in the Supplemental Services Business follow
below.

5.    In accordance with Condition 38A, this Code deals with the disclosure of
information and does not deal with the possibility of unfair advantage arising
from the use of information by a person who works for the Supplemental Services
Business and obtains information in that capacity and at the same time works for
other Businesses such as Systems or Apparatus Supply. However, BT has
established guidelines for its employees about fair trading practices and under
those guidelines employees who receive information in their capacity for the
Supplemental Services Business and, for example , as part of the same
transaction make a sale of apparatus are required to inform customers that they
can obtain apparatus from competitors if they wish to do so.

6.    Disclosure of certain information about the use made of public
telecommunication systems otherwise than in the course of duty may also be a
criminal offence under Section 45 of the Telecommunications Act 1984 (as
replaced by Schedule 2 to the Interception of Communications Act 1985).


<PAGE>
Trading Agreement 658130                      Schedule 1 - Terms and Conditions


THE CODE

WHAT IS SUPPLEMENTAL SERVICES BUSINESS

7.  'Supplemental Services Business' is defined within Condition 18 of the
Licence. Broadly, it is:

    -     the provision of any service which could have been provided on 1 April
          1987 under and in accordance with the Class Licence for the running of
          telecommunication systems providing value added and data services
          granted by the Secretary of State on 1 April 1987, (effectively any
          service provided by BT which could be provided by a competitor under
          the Class Licence for value added and data services), together with

    -     activities such as installation, maintenance, adjustment, repair,
          alteration, moving, removal or replacement of any apparatus comprised
          in any of BT's systems used, wholly or partly, for providing those
          services.

8.    This Code of Practice applies to all customer information which is
      acquired by BT in the provision of telecommunication services for a
      consideration in the course of its Supplemental Services Business. This
      may include details of the customer's telecommunication and computing
      systems provided to enable compatible connections with BT's systems, or
      details of services with which the customer is being provided.

9.    Where BT acquires any customer information to which this Code applies it
      must be assumed that the information has been supplied or gained in
      confidence. This information must not be disclosed outside the
      Supplemental Services Business without the customer's recorded prior
      consent. A customer shall only be held to have given such consent where
      that consent was given by way of a specific response to a request by BT.
      Information may be passed to persons within that part of BT also dealing
      with the provision of telecommunication services without the customer's
      prior recorded consent, for the internal purposes of BT, where those
      persons have a valid operational requirement for the information. In such
      cases its status as confidential information must be made clear to the
      recipient and such recipients must be made aware of their responsibilities
      under this Code.

10.   Those responsible for collecting and storing confidential customer
      information must ensure that it is kept confidential, and that it is not
      disclosed to any BT employee except as permitted by paragraph 9 above
      subject to the exceptions below.

      EXCEPTIONS

11.   There are five exceptions to the normal procedure described above.

        a)   In the investigation of any criminal offence or as specifically
             permitted by law. BT discloses information without customer consent
             where necessary in the

<PAGE>
Trading Agreement 658130                      Schedule 1 - Terms and Conditions


             prevention or detection of a criminal offence, in the interests of
             national security or as specifically permitted by law, e.g. for the
             purpose of any criminal proceedings;

        b)   Accounts; details of a customer's individual account may be
             disclosed by any BT employee without that customer's consent when
             the disclosure falls within the exceptions listed in (a) above or
             is in the course of his duty in the Supplemental Services Business.
             For example to the extent necessary to avoid bad debts or as
             required by auditors.

        c)   Information already in the public domain or which has been supplied
             to BT in order to be published may be disclosed without customer
             consent.

        d)   Statistical information derived from customers' records may be
             passed outside the Supplemental Services Business only if the
             customer concerned cannot be identified from the information.

        e)   Information for the purpose of complying with BT's obligations
             under the Licence may be disclosed without specific customer
             consent.

      COMPLYING WITH THE CODE

12.   BT will take all reasonable steps to ensure that those engaged in the
      Supplemental Services Business, or involved in handling customer accounts,
      read this Code and understand it. If in any doubt about how to apply the
      Code, employees should consult their manager for advice.

13.   Observance of this Code is mandatory and Senior Management attach the
      greatest importance to compliance with it at all times.

       and the Support Agreement both of even date herewith, completely and
       exclusively state the agreement of the parties regarding the subject
       matter hereof and thereof.  In the event of any conflict between the
       terms of this Agreement and the License Agreement or the Support
       Agreement, the terms of such other agreement shall control with respect
       to the subject matter of such agreement.  This Agreement supersedes, and
       its terms govern, all prior proposals, agreements or other communications
       between the parties, oral or written, regarding the subject matter of
       this Agreement.  This Agreement shall not be modified except by a
       subsequently dated written amendment signed on behalf of C1 and MCIS by
       their duly authorized representatives, and any purchase order purporting
       to supplement or modify the provisions hereof shall be void.

       the terms and conditions of the main body of this Agreement, in which
       case the terms and conditions of the main body of this Agreement shall
       prevail in all respects, and those of the Schedules shall prevail over
       those of the Exhibits.

1.7    SEVERABILITY. In the event that any provision of this Agreement shall be
       unenforceable or invalid under any applicable law or be so held by
       applicable court decision, such unenforceability or invalidity shall not
       render this Agreement unenforceable or invalid as a whole and, in such
       event, any such provision shall be changed and interpreted so as to best
       accomplish the objectives of such unenforceable or intended provision
       within the limits of applicable law or applicable court decisions.

5.0    SALES COMMISSIONS

5.1    C1 shall pay MCIS 5% of each MCI-based ECN transaction fee paid by any
       C1 Customer during the term of this Agreement where such Customer has not
       engaged MCIS to provide systems integration services.  C1 shall pay MCIS
       10% of each MCI-based ECN transaction fee paid by any C1 Customer during
       the term of the Agreement where such Customer has engaged MCIS to provide
       systems integration services and MCIS performs such integration services.
       For purposes of this Section 5.1, "MCI-based ECN transaction fee" shall
       mean fees, to the extent received in cash by C1, from Customers whose C1
       proprietary electronic commerce networks ("ECN") are hosted by an MCIS
       Affiliate with respect to transactions executed over such networks.  It
       is understood and agreed that "MCI-based ECN transaction fees" shall not
       include license fees, maintenance and

____________________________

<PAGE>

       support fees, professional service or consulting fees or any other amount
       not expressly included within the definition of "MCI-based ECN
       transaction fees" above.

5.2    With respect to any C1 licenses entered into during the term of the
       Agreement for which MCIS provides systems integration services (whether
       such services are provided as a subcontractor to C1, directly to the
       Customer by MCIS or by MCIS through a third party subcontractor) to the
       Customer, C1 shall pay MCIS (i) 15% of all such license fees payable by
       Customers or distributors to C1 for SAP-based accounts (i.e., accounts
       where the Customer has implemented, contracted to implement, or has
       otherwise identified that it intends to implement SAP America, Inc.'s
       and/or its affiliate's proprietary enterprise resource planning software
       solution), and (ii) 20% of all such license fees payable by Customers or
       distributors to C1 for all accounts that are not SAP-based accounts as
       defined above.  For purposes of this Section 5.2, "license fees revenue"
       shall mean license fees payable to C1 for C1 software.  It is understood
       and agreed that "license fees revenue" shall not include any amounts
       received by C1 for transaction fees, maintenance and support fees,
       professional service or consulting fees or any other amount not expressly
       included within the definition of "license fees revenue" above.

5.3    With respect to any C1 licenses entered into during the term of the
       Agreement which do not fall within the scope of Section 5.2 hereof, but
       for which MCIS or it Affiliates provided real sales and marketing
       support - such support including but not limited to participation in
       Customer presentations, sales calls, direct Customer mailings, seminars,
       trade shows or user group activities, - C1 shall pay MCIS (i) 5% of all
       such license fees payable by Customers to C1 where C1 has a contractual
       obligation to provide a sales agency fee or other comparable fee to
       another Preferred Systems Integrator, or to Ernst & Young Technology,
       Inc. or Cambridge Technology Partners, Inc. under either party's Sales
       Agency Agreement in effect as of the Effective Date; and (ii) 10% of all
       such license fees payable by Customers to C1 where C1 has no obligation
       to provide a sales agency fee or other comparable fee to another
       Preferred Systems Integrator or the entities identified under subsection
       (i) above.

5.4    C1 shall provide quarterly reports of commissions due pursuant to
       Sections 5.1, 5.2 and 5.3 hereof and shall pay MCIS any such commissions
       within thirty (30) days of the close of a calendar quarter.

5.5    The rates set forth in Sections 5.1, 5.2 and 5.3 hereof are determined
       based on C1's current business model for delivering its products and
       services to the marketplace.  In the event of any material change to the
       C1 business model or pricing during the term of this Agreement, the
       parties agree to equitably adjust such rates in such a manner as to yield
       a comparable compensation to MCIS.  Any such adjustment shall be
       effective for all transactions impacted by such change in business model
       or pricing.

5.6    In the event C1, pursuant to generally accepted accounting principles,
       writes-off as a bad debt any license fees payable by a Customer for which
       C1 paid a commission to MCIS pursuant to Section 5.2 or Section 5.3, then
       MCIS shall refund to C1 within thirty (30)

                                      8

<PAGE>

       days of receipt of evidence of such bad debt write-off, a PRO RATA
       portion of any commissions paid to MCIS pursuant to Section 5.2 or
       Section 5.3, in either case, calculated based on the ratio of the
       total license fees charged to the applicable Customer to the total
       amount of license fees to be written-off.

       connection with this Agreement, which is not settled to the mutual
       satisfaction of the parties in accordance with the procedures identified

       punitive or exemplary damages.  The decision of the arbitrator(s) shall

       (iii)  material breach of this Agreement by any party with such breach

       divestiture, C1 shall have the option to terminate this Agreement;
       provided C1 refund any and all marketing dollars paid by MCIS or its

       14.1.1 GENERAL INDEMNITY. C1 at C1's own expense, shall defend, hold

              expenses (including without limitation reasonable attorneys' fees)
              arising from: (a) third party claims that the C1 Software or any
              other Services performed or delivered by C1 to MCIS, its
              Affiliates, or its Customers (i) infringes a copyright or other

<PAGE>

              or the applicable MCIS Affiliate shall: (x) promptly notify C1
              in writing of the claim; (y) grant C1 sole control of the
              defense and all related settlement negotiations; and (z)
              provide C1 with the assistance, information and authority
              necessary to perform C1's obligations under this Section 14.1.
              C1 will reimburse MCIS' and its Affiliates' reasonable
              out-of-pocket expenses incurred in providing such assistance.
              To the extent any failure by MCIS or its Affiliate to perform
              any of the foregoing directly has an adverse impact on C1's
              liability to the applicable third party, C1 shall be entitled
              to reduce the amount of its indemnification exposure hereunder
              by the amount of such adverse impact.  MCIS or its Affiliate
              may, at its own expense, be represented in such defense.

       14.1.2 EXCLUSIONS.  C1 shall have no liability for any claim of
              infringement or misappropriation to the extent based on (i) use of
              other than the latest release of the C1 Software during the period
              of time when the infringement would have been avoided by use of
              the latest release; (ii) modification of the C1 Software by MCIS
              if the infringement would have been avoided without such
              modification; or (iii) the combination or use of the C1 Software
              furnished hereunder with materials not furnished or specified by
              C1 if such infringement would have been avoided by use of the C1
              furnished or specified materials alone.

       14.1.3 ALTERNATIVES.  In the event the C1 Software is held to, or C1
              believes is likely to be held to, infringe any intellectual
              property right, C1 shall have the right at its sole option and
              expense to (i) substitute or modify the C1 Software in a manner
              that is functionally and operationally equivalent and
              noninfringing; or (ii) obtain for MCIS a license to continue using
              the C1 Software as provided in this Agreement; or (iii) if (i) and
              (ii) are not reasonably practicable, terminate this Agreement.

              indemnify C1, its Affiliates, and its and their respective
              directors, officers, employees and agents, from and against any
              and all claims, costs, liabilities, damages, losses or expenses
              (including without limitation reasonable attorneys' fees) arising
              from (a) third party claims that the Services performed or
              delivered by MCIS to C1, its Affiliates, or its Customers (i)
              infringes a copyright or other intellectual property right or
              misappropriates a third party's trade secret under the law of any
              country that is a member of the Berne Convention or (ii) infringes
              any valid patent issued in any country that is a party to the
              Paris Convention; or (b) third party claims of injury to or death
              of any person or loss of or damage to any tangible property to

              omissions of MCIS, its Affiliates or their respective personnel

              C1 Affiliate shall: (x) promptly notify MCIS in writing of the
              claim; (y) grant MCIS sole control of the defense and all related
              settlement negotiations; and (z) provide MCIS with the
              assistance, information and authority necessary to perform MCIS'
              obligations under this sub-Section 14.2.  MCIS will reimburse C1's
              and its Affiliates' reasonable out-of-pocket expenses incurred in
              providing such assistance.  To the extent any failure by C1 or its
              Affiliate to perform any of the foregoing directly has an adverse
              impact on MCIS' liability to the applicable third party, MCIS
              shall be entitled to reduce the amount of its indemnification
              exposure hereunder by the amount of such adverse impact.  C1 or
              its Affiliate may, at its own expense, be represented in such
              defense.

       14.2.2 EXCLUSIVE REMEDY.  THE FOREGOING STATES THE SOLE AND EXCLUSIVE

       earthquakes, material shortages or any other cause which is beyond the
       reasonable control of such party.

15.3   ASSIGNMENT.  This Agreement shall not be assigned by C1 or MCIS in whole
       or in part without the prior written approval of the other party,
       provided either party shall have the right to assign this Agreement in
       connection with the merger or acquisition of such party or the sale of
       all or substantially all of its assets related to this Agreement without
       such consent. Any assignment in violation of this sub-Section shall be
       void and of no effect.  Nothing in this Section 15.3 is intended to

       Agreement to third parties for purposes of delivering Services.

15.4   WAIVER.  The failure of either party to require performance by the other
       party of any provision hereof shall not affect the full right to require
       such performance at any time thereafter; nor shall the waiver by either
       party of a breach of any provision hereof be taken or held to be a waiver
       of the provision itself. No failure on the part of any party hereto to
       exercise and no delay in exercising any right, power or remedy hereunder
       shall operate as a waiver thereof, nor shall any single or partial
       exercise of any right, power or remedy by any party preclude any other or
       further exercise thereof or the exercise of any other right, power or
       remedy.  No express waiver or consent by any party hereto to any breach
       of or default in any term or condition of this Agreement shall constitute
       a waiver or an assent to any succeeding breach of or default in the same
       or any other term or condition hereof.

15.5   WARRANTY. Each party acknowledges that it has read this Agreement,
       understands it and agrees to be bound by it.

15.6   COUNTERPARTS.  This Agreement may be executed simultaneously in two or
       more counterparts, each of which will be considered an original, but all
       of which together will constitute one and the same instrument.

       and be binding upon the parties and their respective successors and
       permitted assigns.

15.8   FURTHER ASSURANCES.         Each party agrees that upon the written
       request of the other party, it shall do all such acts and execute all
       such further documents, conveyances, deeds, assignments, transfers and
       the like, and shall cause the doing of all such acts and shall cause the
       execution of such further documents as are within its powers to cause the
       doing and execution of, as the other Party hereto may from time to time
       reasonably request be done and/or executed as may be reasonably necessary
       to give effect to this Agreement.

15.9   COMPLIANCE WITH LAWS.       Each party shall strictly comply with, and
       abide by, all consents, licenses, and permits that may exist concerning
       its activities and/or performance obligations under this Agreement, and
       each party shall perform its obligations under this

                                      18

       Agreement and otherwise conduct its affairs and business in any
       connection with this Agreement in strict compliance with all laws,
       by-laws, regulations, orders, judgments and governmental rulings and
       decrees.  Without limiting the foregoing, neither party shall attempt,
       or otherwise undertake, to influence the award of a Contract through
       any unethical, illegal, fraudulent, deceptive or misrepresentative
       means whatsoever.

15.10  DUE DILIGENCE.       Each party hereto acknowledges (i) the risks of its
       undertakings hereunder;  (ii)  the uncertainty of the benefits and
       obligations hereunder; and (iii) its assumption of such risks and
       uncertainty.  Each party has conducted its own due diligence and
       requested and reviewed any contracts, business plans, financial
       documents, and other written material as in such party's opinion shall be
       the basis of the party's decision to enter into this Agreement.

15.11  NON-COMPETITION.     The Parties agree and confirm that the
       restrictions set out in this Agreement, including the preferred status
       conferred herein:  (i) are fair and reasonable in the commercial
       circumstances of this Agreement; (ii) reasonably protect the
       legitimate business interests of the parties and do not constitute any
       undue restraint of trade; (iii) are fair and reasonably in the
       interests of the parties because (a) the consideration provided to
       each party under this Agreement adequately and fairly compensates such
       party in connection with such restrictions, and (b) neither party
       would have entered into this Agreement but for the other party's
       agreement with such restrictions and that such restrictions have been
       an inducement to enter into this Agreement.

15.12  NO MERGER.     The parties agree and acknowledge that none of the
       warranties, representations and covenants contained in this Agreement
       shall merge upon either the execution and delivery of this Agreement by
       both parties, or upon the full payment (or any partial payments) of any
       monies that are due and payable hereunder and that all such warranties,
       representations, and covenants shall continue in full force and effect
       throughout the term.

     Commerce One Electronic Commerce Network ("ECN") Services Provider" in
     all C1 originated Software license opportunities worldwide where an ECN
     Services Provider has not already been identified for that specific
     account.  For purposes of this Agreement, "ECN Services Provider" shall
     mean an entity that provides one or more of the following services:
     circuit configuration determination, LAN assessments, REOS hosting,
     circuit ordering, circuit implementation coordination/outsourcing,
     coordination and organization of catalogue content.  In situations where
     a Customer directs C1 to utilize another ECN Services Provider, C1 will
     be free to identify and contract with another ECN Services Provider for
     that specific Customer; provided C1 does not disclose any confidential
     information of MCIS and its affiliates to such other ECN Services
     Provider.

1.3  During the term of the Agreement, C1 will designate only one other
     systems integrator as a having a "preferred" relationship with C1 or any
     other similar designation.

1.4  C1 shall not enter into any other alliance or similar agreements with a
     systems integrator which agreement(s), when viewed as a combined set,
     contain relevant, material terms or conditions that are superior to any
     combined set of material terms or conditions provided to MCIS and that
     put MCIS at a competitive disadvantage.  In the event this provision is
     breached, C1 shall agree to equitably adjust the combined set of MCIS
     terms and conditions to eliminate such competitive disadvantage.  By way
     of example, and not of limitation, C1 shall not offer any pricing terms
     to any other system integrator which could put MCIS at a competitive
     disadvantage.

1.5  C1 shall not enter into any other arrangements with any third party that
     prohibits MCIS from providing Services to C1 Customers  in any markets.

1.6  C1 will be identified by MCIS as the "preferred product" in all electronic
     procurement opportunities where a product solution has not already been
     identified for that specific account.  Both parties will promote the
     relationship to the Customer.

1.7  The following principles govern the pursuit of Customer Opportunities and
     the Services to be provided by the parties:

     (a)  The Customer has the sole and final right to approve or disapprove the
          C1/MCIS relationship.


<PAGE>

     (b)  In situations where MCIS brings C1 into a Customer Opportunity both
          parties will work together in completing the transaction, however if
          MCIS is not willing or able to close the service integration portion
          of the transaction, C1 is permitted to partner with another systems
          integration partner; provided C1 does not disclose any Confidential
          Information of MCIS and its affiliates to such other systems
          integration partner.

     (c)  In situations where C1 brings MCIS into a Customer Opportunity both
          parties will work together in completing the transaction, however if
          C1 is not willing or able to close the product portion of the
          transaction, MCIS is open to partner with another system product
          company; provided MCIS does not disclose any Confidential Information
          of C1 and its affiliates to such other system product partner.

     (d)  In situations where either another product company chooses to bring
          MCIS into an account or where another system integrator chooses to
          bring C1 into an account, each party has the ability to complete
          that transaction with such other party.

     (e)  When C1 is working with another systems integration partner and
          that systems integration partner or the applicable Customer or
          prospective Customer identifies services that require additional
          resources or resources with skill sets outside the capabilities of
          such systems integration partner, C1 will recommend each Preferred
          Provider (subject to the Customer's discretion) to be engaged to
          perform such services.

     (f)  Within 30 days of executing the definitive agreement, MCIS and C1
          agree to develop further detailed mutually agreed to sales "rules
          of engagement".

2.0  JOINT RELATIONSHIP MANAGEMENT.

2.1  C1 will implement a Quarterly Product Advisory Committee meeting that will
     allow for the inclusion of the MCIS Chief Technology Officer or his/her
     designee (as may be reasonably acceptable to C1).

2.2  C1 and MCIS will each designate dedicated individuals responsible for
     the joint relationship, sales pipeline management, and an executive
     sponsor and such designated persons will have sufficient authority for
     the role.

2.3  MCIS and C1 will each identify and provide advocates of the C1/MCIS
     solution in the form of sales and marketing resources to industry
     vertical and geographical markets as appropriate.

<PAGE>

2.4  Except in those circumstances where C1 has been jointly involved in a
     sales and marketing opportunity with another systems integrator (to the
     extent such involvement is not otherwise prohibited by, or in violation
     of, this Agreement) or where another systems integrator has been
     identified by the Customer, MCIS shall have the right to participate as
     a preferred systems integrator in account-specific sales activities or
     any subsequent or similar marketing or sales team initiatives or
     approaches. Where MCIS, in its discretion and for any reason, notifies
     C1 on a case-by-case basis that shall not participate in any such team
     or activity, C1 has no further obligation to recommend MCIS for that
     opportunity.

2.5  Each party agrees to share with each other their respective "lead" and
     prospect lists related to electronic procurement, solely for the purpose
     of conducting joint sales and marketing in accordance with this
     Agreement.  The obligation to provide such leads shall not apply, in
     each party's case, to those circumstances where one party is working
     with a different systems integrator or solution provider (as the case
     may be) to the extent not prohibited by, or otherwise in violation of
     this Agreement.

2.6  Upon C1's request from time to time, MCIS shall use reasonable
     commercial efforts to identify those MCIS Affiliates who are engaging in
     sales and marketing efforts with respect to the C1 Software.

2.7  During calendar year 1998, MCIS shall commit to train a minimum of 75
     MCIS personnel to perform MCIS' obligations hereunder (including both
     sales-related, and Services-related obligations).  Such training shall
     be provided by C1 as part of the complementary training provided in
     accordance with Section 2.8 of this Schedule A.

2.8  On a schedule reasonably acceptable to both parties, C1 will provide up
     to 200 training days per calendar year during each year of the term of
     the Agreement for training MCIS internal staff in the marketing, sale,
     support, use, implementation and operation of the C1 Software.  For
     purposes of this calculation, a "training day" shall refer to one
     calendar day of instruction provided by a C1 instructor for one MCIS
     trainee.  Furthermore, a training day could take place as either
     structured classroom training or on-site at a Customer location. It is
     also the intent of both parties to execute a training strategy whereby
     C1 is "training the trainers" at MCIS.  At MCIS' option, MCIS can
     purchase additional training days from C1, in advance, for a reduced fee
     as follows:  (i) for purchases of 1-299 training days a discount of 33%
     off of the then current list price will apply, and (ii) for purchases of
     greater the 300 training days, a discount of 40% off of the then current
     list price will apply.  Training priced under this discount must be
     purchased at least thirty (30) days in advance.  Any training credits
     (e.g.., the 200 days provided at no charge to MCIS or any days purchased
     in advance) remaining unused at the end of the each year will expire. C1
     will send to MCIS a quarterly report on the status/balance of such
     unused training credits.  MCIS when ordering training to be applied
     against the purchased training credit amount should quote a reference
     purchase order number to ensure credit against the prepaid training
     credit balance.  The Agreement will include a mutually acceptable
     cancellation policy for scheduled training classes. It is understood

<PAGE>

     that all C1 technical training shall be provided at C1's Walnut Creek,
     California facilities, and sales training will be provided at MCIS
     regional offices or other similar facilities which will be made
     available and paid for by MCIS and MCIS shall pay all costs and expenses
     of C1 including C1 travel and living expenses in accordance with MCIS's
     travel policy which is attached to the Software License Agreement.

2.9  C1 and MCIS shall jointly prepare a Project Progress Report, in an
     agreed format and on an agreed frequency (initially monthly), that
     summarizes activities in all joint functional execution areas.

3.0  MARKETING AND SALES PROGRAMS.

MCIS and C1 will each contribute at least $150,000 towards the development
and execution of joint marketing and sales programs for calendar year 1998.
MCIS and C1 will consider making similar contributions, and increasing such
contribution up to an additional $350,000 each for calendar years 1999, 2000
and 2001 based on the performance of the overall program; provided that in
the event either party elects not to contribute at least $150,000 for each
calendar year, then the other party shall have the option of terminating this
Agreement without penalty upon thirty (30 days prior written notice.
Expenditure of the combined marketing and sales program funds shall be only
as mutually agreed upon.  Any funds not expended for a particular year shall,
on agreement of the parties, be refunded to the parties, PRO RATA, or shall
be applied toward the fund commitment for the following year.  The programs

4.1  During the term of the Agreement, MCIS may, in its discretion, develop
     vertical and horizontal template solutions to support its systems
     integration efforts under the Agreement.  C1 authorizes MCIS to create
     such templates and will provide up to 100 hours per calendar year of
     support and assistance to MCIS in such development at no charge to MCIS.
     All support provided at no charge shall be subject to the reasonable

                                                         Exhibit 10.13

                                    AGREEMENT


         This Agreement (the "Agreement") is entered as of the _____ day of
September, 1998, by and between Commerce One, Inc. ("C1"), a California
corporation with a principal place of business at 1600 Riviera Avenue, Walnut
Creek, California 94596 and PricewaterhouseCoopers LLP ("PwC"), a registered
Delaware limited liability partnership with offices located at 1177 Avenue of
the Americas, New York, NY 10036 (each, a "Party" and together the "Parties").

         C1, among other things, develops, markets, sells and supports
enterprise-level software applications and services that enable businesses and
their suppliers to engage in electronic procurement and supplier management over
the Internet and other communications media (the "C1 Software").

         PwC, among other things, assists companies like C1 in the development,
marketing, and sale of such software systems and services and implements and
supports these systems for customers who have purchased them.

         Because of the complementary knowledge and expertise of the Parties,
the Parties desire to enter into an alliance under which they will work together
to develop, market, sell, implement and support the C1 Software.

         Now, therefore, in consideration of the mutual promises contained
herein and for other good and valuable consideration, the receipt and
sufficiency of which are hereby mutually acknowledged, the Parties agree as
follows:

1.       DEFINITIONS

         As used herein, the following terms shall have the following meanings:

                       (including their constituent elements and code in
                       whatever form, whether proprietary to C1 or others) as
                       they now exist or as they are further developed and
                       shall include all software, related databases, design

                       lists, know-how, and all other information of whatever
                       nature related to or incorporated into C1 Software or
                       the business of C1 or PwC or any subsidiary or other
                       business entity which is an affiliate of C1 or PwC
                       (such subsidiary or business entity referred to
                       collectively as "C1" or "PwC", as the case may be) and
                       which is reasonably understood to be of a confidential
                       nature. Confidential Information includes information
                       of others that C1 or PwC has agreed to keep
                       confidential. Confidential Information of PwC

                       services relating to the C1 Software. Confidential
                       Information of a Party shall not include information
                       or materials that is disclosed to the other party (the

                        (i) otherwise rightfully known to the Receiving
                            Party;

                       (ii) in the public domain through no fault of the
                            Receiving Party;

                      (iii) lawfully obtained by the Receiving Party
                            from a third party without breach of such third
                            party's obligations of confidentiality; or

                       (iv) that a Receiving Party is required to disclose by
                            legal process; provided, however, that voluntary
                            disclosure beyond that which is required by law
                            shall constitute a violation of this Agreement.

                       disclosed to PwC by C1 or to C1 by PwC, that are
                       commercially valuable and secret. Trade Secrets are
                       unique assets of C1 or PwC that give C1 or PwC a
                       competitive advantage over competitors that do not
                       possess such information. Trade Secrets include, but
                       are not limited to, system designs and specifications,
                       programming sequences, algorithms, flow charts, and

                       product to which additional or incremental
                       functionality has been added.

2.        COOPERATION IN C1 SOFTWARE DEVELOPMENT AND IMPLEMENTATION

          2.1 ESTABLISHMENT OF THE TRC. To enhance the performance,
              development and implementation of C1 Software, the Parties will
              establish a Technical Review Committee ("TRC"). The intended
              objective of the TRC is to provide advice to C1 regarding
              functionality, priorities, release schedules, and use of
              development resources.

          2.2 SCOPE OF THE TRC'S REVIEW. The TRC shall be charged with
              reviewing the performance of the C1 Software, all developments
              or potential developments to the C1 Software and the
              implementation of the C1 Software.

          2.3 MEMBERSHIP OF THE TRC. The TRC shall be composed of three C1
              employees selected by C1 who are involved in and knowledgeable
              about the performance and development of C1 Software and three
              PwC employees selected by PwC who are involved in and
              knowledgeable about the implementation of C1 Software. C1 and
              PwC may at any time with notice to the other Party change their
              employees designated to serve as members of the TRC. Each Party
              represents that its designated members of the TRC are
              authorized to act on that Party's behalf on all matters that
              come before the TRC.

          2.4 MEETINGS AND REPORTS. The TRC shall meet at least quarterly to
              review and assess the performance of the C1 Software, all
              developments or potential developments to that software and the
              implementation of that software. At least once every six
              months, the TRC shall issue a report to C1 and PwC reviewing
              and assessing in detail the above. In the event that the
              members of the TRC do not concur in their review and
              assessment, the report shall so state and shall set forth
              separately the review and assessment of all members.

          2.5 OBLIGATION TO PROVIDE INFORMATION TO THE TRC. C1 and PwC shall
              each promptly provide to the TRC all material information known
              or available to each of them relating to the performance of the
              C1 Software, all material developments or potential
              developments to the C1 Software, and the implementation of the
              C1 Software. This obligation includes but is not limited to
              providing the TRC with all Beta releases, with all information
              relating to C1 Software Upgrades, and with all information
              relating to problems with C1 Software performance or
              implementation.

3.       OPERATION IN C1 SOFTWARE MARKETING

          3.1 ESTABLISHMENT OF MDC. To enhance the marketing of C1 Software,
              the Parties will establish a Marketing Development Committee
              ("MDC").

          3.2 SCOPE OF THE MDC'S REVIEW. The MDC shall be charged with
              developing and overseeing the joint marketing of C1 Software
              based upon the initial marketing plan and budget to be agreed
              upon and entered into by the Parties within 30 days of the date
              hereof (the "Marketing Plan"). The MDC shall agree upon not
              less than five customers to serve as beta integration sites
              with respect to the C1 Software. The MDC shall also identify
              each party's commitments and obligations, including joint
              activities. The MDC shall consider using marketing tools such
              as, among other things, magazine inserts in publications such
              as Forbes, methodology books (for pre-sale), PwC sponsored
              conferences, and training forums.

          3.3 COMMITMENT OF THE PARTIES. The specific monetary and in-kind
              commitments of the Parties shall be determined by the MDC in
              accordance with the Marketing Plan; provided, however, PwC
              agrees that it shall spend a minimum of $250,000 the first year
              this Agreement is in effect pursuant to jointly approved plans
              for the marketing of the C1 Software. Thereafter, the Parties
              shall determine in good faith the amount per year that each
              Party shall commit to the marketing of the C1 Software;
              provided that in the event that the parties are unable to agree
              upon the minimum amount to be spent by PwC for marketing in any
              subsequent year, the minimum amount shall be $250,000.

          3.4 MEMBERSHIP OF THE MDC. The MDC shall be composed of two C1
              employees selected by C1 and two PwC employees selected by PwC,
              all of whom are involved in the marketing of C1 Software. C1
              and PwC may at any time with notice to the other Party change
              their employees designated to serve as members of the MDC. Each
              Party represents that its designated members of the MDC are
              authorized to act on that Party's behalf on all matters that
              come before the MDC; provided that in no event shall the MDC
              have the authority to modify the terms of this Agreement

          3.5 MEETINGS. The MDC shall meet at least quarterly to develop and
              oversee C1 Software marketing.

          3.6 PUBLICITY. The MDC shall establish guidelines governing all
              news releases, public announcements, or any other mass
              publicity, including without limitation, mass-produced
              marketing materials, which makes reference to PwC or includes a
              Mark (as defined below) of PwC or New Mark (as defined below)
              (collectively, "Publicity") to be released by either Party
              relating to C1 Software. Notwithstanding the foregoing, C1
              shall not release any Publicity relating to PwC unless such
              Publicity is approved by PwC. The MDC shall establish
              guidelines governing all news releases, public announcements,
              or any other publicity which makes reference to C1 or includes
              a Mark (as defined below) of C1 (collectively, "C1 Publicity")
              to be released by either Party relating to C1 Software.
              Notwithstanding the foregoing, PwC shall not release any C1
              Publicity relating to C1 unless such C1 Publicity is approved
              by C1.

          3.7 TRADEMARKS, LOGOS, TRADE NAMES AND SERVICE MARKS. The MDC shall
              establish written guidelines governing the use by a Party of
              trademarks, logos, trade names and service marks (together
              "Marks") of the other Party or any successor entity to either
              of the Parties; provided, however, C1 shall not use PwC's Marks
              unless the use is approved by PwC and PwC shall not use C1's
              Marks unless the use is approved by C1. Notwithstanding any
              other provision contained herein or in any guidelines
              established by MDC, in the event that PwC gives C1 notice that
              it is terminating this Agreement pursuant to Section 11.3.2, C1
              shall immediately cease, and in the event the Agreement is
              terminated for any other reason, upon termination C1 shall
              cease, the use of the names "Price Waterhouse,"
              "PricewaterhouseCoopers", the mark "PW," "PwC," any derivations
              thereof or any other mark proprietary to PwC, including without
              limitation any other new or successor trade

                                       -4-

              name, logo, trademark or service mark which evolves as a result
              of the recent merger between Price Waterhouse LLP and Coopers &
              Lybrand LLP (together, the "New Marks"), in connection with the
              marketing, promotion, Publicity and sale of the C1 Software.
              Notwithstanding any other provision contained herein or in any
              guidelines established by MDC, in the event that C1 gives PwC
              notice that it is terminating this Agreement pursuant to
              Section 11.3.2, PwC shall immediately cease, and in the event
              the Agreement is terminated for any other reason, upon
              termination PwC shall cease, the use of the name "Commerce
              One," the mark "C1", any derivations thereof or any other mark
              proprietary to C1.

          3.8 MARKETING MATERIALS. In addition to any other guidelines set
              forth by the MDC, (i) all C1 created brochures and marketing
              materials relating to the C1 Software shall contain a statement
              that C1 and PwC are strategically aligned and that PwC is a
              preferred systems integration and consulting partner, and (ii)
              all references to third party integration and consulting
              partners shall be made in such a manner as to preserve the
              preferred implementor status of PwC. MCI Systemshouse shall be
              the only other entity designated or allowed to hold itself out
              as a preferred systems integrator and consulting partner of C1.

4.        BETA PRODUCTS; BETA INTEGRATION SITES

          4.1 BETA PRODUCTS. C1 shall provide to PwC advance copies and beta
              releases of all C1 Software as soon as reasonably possible.

          4.2 BETA INTEGRATION SITES. The MDC will agree upon not less than
              five customers to serve as beta integration sites with respect
              to the C1 Software. PwC shall perform the implementation
              functions relative to such C1 Software at such beta integration
              sites. PwC shall perform such implementation services at a
              price necessary to attract the agreed upon customers to
              participate in such testing while attempting to minimize the
              extent to which billing rates are discounted; however, for the
              first three customers, PwC shall use reasonable commercial
              efforts to perform such services at discounted rates but shall
              not be required to discount such rates below forty five percent
              (45%) of PwC's stated rates for such services for the first
              three customers, or below fifty-five percent (55%) of PwC's
              stated rates for such services for the fourth and fifth
              customers. C1 will use reasonable commercial efforts to license
              the C1 Software at a price necessary to attract the agreed upon
              customers to participate in such integration and will supply
              necessary technical expertise and support with respect to the
              beta integration site implementations under a mutually agreed
              upon timetable.

5.       C1 SOFTWARE SALES

              either directly to clients or sell it to PwC who will resell it
              to clients; provided that, direct sales to clients will comply
              with the provisions set forth in Section 5.1.1 below and sales
              to PwC for resale will comply with the provisions set forth in

              client contract will provide that:

                       discount which shall not be less than any other
                       reseller's discount, except for SAP; provided,
                       however, PwC shall be entitled to the same discount
                       offered to SAP in situations where PwC is in direct

                       event shall such discount be less than 30%. PwC may
                       charge the client such amounts as PwC may determine in

                       mutually acceptable terms customary for the software

                       PwC's EPS Practice becomes aware, except for those
                       opportunities which are brought to the attention of
                       PwC by another MRO (indirect) electronic procurement
                       solutions provider;

              (i)      PwC shall provide to C1, on a timely, periodic and
                       confidential basis, advance information collected by
                       PwC's EPS Practice regarding potential customer
                       prospects with respect to an MRO (indirect) electronic
                       procurement solution;

              (j)      PwC's EPS Practice shall not engage in any active
                       pattern of promotion with respect to any third party
                       as an MRO (indirect) electronic procurement solution
                       provider; and

              (k)      Within 120 days following the execution of this
                       Agreement, C1 shall be included in PwC's solution
                       center network.

         6.3  RIGHT OF FIRST REFUSAL. PwC shall have a right of first refusal
              with respect to other consulting and systems implementation
              firms with respect to any consulting project of total value
              greater than $500,000 (i.e. the total billable work for such
              project exceeds $500,000) performed for C1 in relation to the
              C1 Software; provided that this section 6.3 shall not apply to
              any joint development agreement entered into by C1 that
              otherwise complies with the terms of this Agreement. This right
              of first refusal is not intended to apply to consulting work to
              be performed for clients of C1. Within 20 days following a
              determination by C1 that C1 requires consulting services, C1
              shall notify PwC of such determination and C1 and PwC shall
              negotiate in good faith regarding the terms of PwC's
              involvement in the consulting project (the "Project"). If C1
              and PwC cannot agree upon the terms of PwC's involvement within
              30 days of PwC's receipt of such notice, C1 shall be entitled
              to enter into an agreement with a third party to perform the
              Project on terms and conditions not less favorable to C1 than
              those last offered by PwC with respect thereto.

          6.4 ATTENDANCE AT BOARD MEETINGS. Throughout the term of this
              Agreement, PwC shall be entitled to observe meetings called or
              held by the Board of Directors of C1 and to receive materials
              provided or distributed to the Board of Directors of C1 as
              provided in the Observers Rights Agreement attached hereto as
              Exhibit B.

          6.5 Requirements FOR OTHER SYSTEMS IMPLEMENTORS. C1 shall require
              each third party systems implementor, other than MCI
              Systemshouse, to pass a certification qualification test within
              six (6) months of beginning implementation of C1 Software
              products. The requirements of such certification tests shall be
              jointly agreed upon by C1 and PwC and shall be administered by
              C1; provided that in the event the Parties are unable to agree
              on such requirements after a period of twenty (20) days, C1
              shall develop commercially reasonable requirements.

          6.6 MOST FAVORED IMPLEMENTOR STATUS. Except for SAP but subject to
              Section 5.1.2(c), the price of the C1 Software sold by C1 to
              PwC for resale or for use by PwC shall be equal to or lower
              than the lowest price charged by C1 to any other systems
              implementor reseller, including MCI Systemshouse with regard to
              the prices and other material terms and conditions provided to
              such other implementor, when considered collectively.

          6.7 OPTIONAL EQUITY INVESTMENT. For 120 days following the
              execution of this Agreement, PwC shall have the option, but not
              the obligation, to purchase shares of Series D Preferred Stock
              at a price equal to 125% of the lowest price paid by the Series
              D Preferred Stock investors in the Series D Preferred Stock
              financing. Such purchase shall be on the terms and conditions
              as set forth in the Series D Preferred Stock financing
              agreements. Notwithstanding the foregoing, in no event shall
              PwC's investment be less than $2,500,000 or more than
              $5,000,000 upon exercise of the rights granted in this Section.

7.        PERSONNEL AND TRAINING

          7.1 PwC PERSONNEL. For the first year after the Effective Date of
              this Agreement and pursuant to and subject to the terms and
              conditions set forth in the Human Resources Agreement to be
              agreed upon and entered into by the Parties within 30 days of
              the date hereof (the "Human Resources Agreement"), PwC shall
              provide C1 with a total of 18,000 man-hours to be performed by
              various PwC personnel and/or consultants of PwC (the "PwC
              Staff") and one partially dedicated PwC partner (the "PwC
              Partner") plus certain ancillary support associated with the
              employment of these people, including, without limitation,
              items such as payment of salaries (including without
              limitation, employee benefits and applicable withholding taxes,
              such as FICA, worker's compensation, unemployment and other
              like items) and provision of laptop computers and computer
              software (the "Support"). In the event that C1 does not utilize
              all 18,000 hours during such year and this Agreement is still in
              effect, C1 shall be entitled to carry over up to 2,700 unused
              hours to the next year


                                       -9-
<PAGE>


for no additional cost. PwC and C1 shall determine in good faith the amount
of resources required from time to time based upon the needs of C1 and the
availability of the PwC Staff; provided, however, no PwC Human Resources (as
defined below) shall be provided to C1 until such time as the Human Resources
Agreement has been executed by the Parties. The PwC Partner shall devote a
sufficient amount of his/her professional time in order for him/her to carry
out his/her responsibilities under this Agreement. The PwC Staff and the PwC
Partner shall be responsible for assisting C1 with product enhancement,
quality assurance, testing procurement consulting and sales support and
implementation activities. Subject to the terms of the Human Resources
Agreement, PwC shall have the right to rotate various people between the C1
headquarters in Walnut Creek, California (the "C1 Headquarters") and various
client sites. Notwithstanding the foregoing, PwC's obligation to provide the
18,000 hours, the PwC Partner and the Support (collectively, the "PwC Human
Resources") shall cease (i) immediately in the event (a) C1 is dissolved or
liquidated, (b) PwC gives C1 notice of its intention to terminate the
Agreement pursuant to Section 11.3.2, or (c)the Human Resources Agreement is
terminated, or (ii) upon termination, in the event PwC gives C1 75 days'
written notice (the "Termination Notice") of PwC's decision to terminate this
Agreement pursuant to Section 11.3.1; provided, however, in the event that
PwC gives C1 the Termination Notice, PwC shall continue to provide the PwC
Human Resources during the 75 day notice period as is necessary in order to
complete, to the extent possible, any current projects on which the PwC Staff
and/or the PwC Partner are working.

          7.2 TRAINING. During the first 12 months of the Agreement, PwC
              shall commit to train a minimum of 25 PwC personnel to perform
              PwC's obligations hereunder (including both sales-related, and
              Services-related obligations). Such training shall be provided
              by C1 as part of the complimentary training provided in
              accordance with details below, or at PwC's discretion, by a PwC
              trainer.

         On a schedule reasonably acceptable to both parties, C1 will provide up
to three training days per trainee per calendar year during each year of the
term of the Agreement for no more than 100 trainees in the marketing, sale,
support, use, implementation and operation of the C1 Software. For purposes of
this calculation, a "training day" shall refer to one calendar day of
instruction provided by a C1 instructor for one PwC trainee. A training day
could take place as either structured classroom training or on-site at a client
location. The parties intend to execute a training strategy whereby C1 is
"training the trainers" at PwC. At PwC's option, PwC may purchase additional
training days from C1, in advance, for a reduced fee as follows: (i) for
purchases of 1-299 training days, a discount of 33% off of the then current list
price will apply, (ii) for purchases of greater the 300 training days, a
discount of 40% off of the then current list price will apply. Training priced
under this discount must be purchased at least thirty (30) days in advance. Any
training days purchased but not utilized or any free training days (i.e., the 3
days provided at no charge to PwC for 100 trainees) remaining unused at the end
of the each year will expire. C1 will send to PwC a


                                       -10-
<PAGE>


quarterly report on the status/balance of such unused training days. PwC when
ordering training to be applied against the purchased training credit amount
shall quote a reference number from the applicable purchase order to ensure
credit against the prepaid training day balance. The Parties shall agree on a
mutually acceptable cancellation policy for scheduled training classes. It is
understood that all C1 technical training shall be provided at C1's Walnut
Creek, California facilities, at no cost to PwC, and sales training will be
provided at PwC regional offices or other similar facilities which will be made
available by PwC and PwC shall pay the out-of-pocket cost of travel plus lodging
of the C1 representative performing the training.

         C1 shall provide to PwC sufficient copies of C1 Software and related
materials as shall be reasonably required for the training of the PwC personnel;
provided that such copies shall be used by PwC solely for internal training
purposes. C1 shall be entitled to receive adequate training by PwC on PwC's full
value procurement system for up to 20 training days per calendar year, at no
cost to C1 if such training takes place at one of PwC's offices as designated by
PwC, or for the out-of-pocket cost of travel plus lodging of the PwC
representative performing the training, if such training is performed at a C1
office or another location designated by C1.

          7.3 PWC SERVICES FEE. In consideration of PwC supplying the PwC
              Human Resources, after the parties have entered into the Human
              Resources Agreement, PwC shall be entitled to receive a fee
              equal to 5% of C1's license fee revenues, up to a maximum fee
              of $3,500,000. In the event the relationship between license
              fees, revenues and other revenues received by C1 from its
              licensees (i.e., consulting fees, maintenance fees and support
              fees) differs materially from C1's business plan as it exists
              on the date hereof and as disclosed to PwC, the parties shall
              negotiate the fees due under this Section 7.3 in good faith.
              For purposes of this Section 7.3, "license fee revenues" shall
              mean license fees, to the extent received in cash by C1, net of
              withholding taxes and other deductions, from customers;
              provided that it is understood and agreed that "license fee
              revenues" shall not include any amounts received by C1 for
              maintenance and support services, consulting or professional
              service fees, any transaction fees or any other amount or
              payment for goods or services not expressly included within the
              definition of "license fee revenues" set forth above. Such fee
              shall be paid quarterly in arrears; provided, however, in the
              event that this Agreement is terminated by C1 or by PwC
              pursuant to section 11.3.2 below, or there is a Change of
              Control of C1, prior to PwC being paid the full $3,500,000
              under this Section 7.3, PwC shall be entitled to be paid a pro
              rata amount of $3,500,000 based upon the number of hours of the
              PwC Human Resources that have been provided to C1 out of 18,000
              hours. For example, if PwC provides 9,000 hours of the PwC
              Human Resources, PwC shall be entitled to be paid 5% of C1's
              gross revenues, up to a maximum fee of $1,750,000 (or 1/2 of
              $3,500,000).

         In the event that there is a Change in Control of C1, all remaining
amounts due to PwC under this Section 7.3 shall become immediately due and
payable to PwC regardless of the amount of C1's license fee revenues on that
date.

         For purposes of this Agreement, a Change in Control shall mean the
occurrence of one or more of the following events:


                                       -11-
<PAGE>


              (a)      the direct or indirect sale, lease, exchange or other
                       transfer of all or substantially all of the assets of
                       an entity to any person or entity or group of persons
                       or entities acting in concert as a partnership or
                       other group (a "Group of Persons");

              (b)      the consummation of any consolidation or merger of an
                       entity with or into another corporation with the
                       effect that the stockholders of such entity
                       immediately prior to the date of the consolidation or
                       merger hold immediately after such merger or
                       consolidation less than 51% of the combined voting
                       power of the outstanding voting securities of the
                       surviving entity of such merger, or the corporation
                       resulting from such consolidation, ordinarily having
                       the right to vote in the election of directors (apart
                       from rights accruing under special circumstances)
                       immediately after such merger or consolidation;

                  (c)  the stockholders of an entity shall approve any plan
                       or proposal for the liquidation or dissolution of such
                       entity;

                  (d)  a person or entity or Group of Persons acting in
                       concert as a partnership, limited partnership,
                       syndicate or other group shall, as a result of a
                       tender or exchange offer, open market purchases,
                       privately negotiated purchases or otherwise, have
                       become the direct or indirect beneficial owner (within
                       the meaning of Rule 13d-3 under the Exchange Act of
                       1934, as amended) of securities of an entity
                       representing 30% or more of the combined voting power
                       of the then outstanding securities of such entity
                       ordinarily (and apart from rights accruing under
                       special circumstances) having the right to vote in the
                       election of the directors; and

                  (e)  a person or entity or Group of Persons, together with
                       any affiliates thereof, shall succeed in having a
                       sufficient number of its nominees elected to the Board
                       of Directors of an entity such that such nominees,
                       when added to any existing directors remaining on the
                       Board of Directors of such entity after such election
                       who are affiliates of such person, entity or Group of
                       Persons, will constitute a majority of the Board of
                       Directors of such entity.

8.       CONFIDENTIALITY; INTELLECTUAL PROPERTY

          8.1 CONFIDENTIALITY GENERALLY. During the term of this Agreement
              and for a period of three (3) years from the termination of
              this Agreement (and for a period of ten (10) years from the
              termination of this Agreement in the case of source code), each
              Party hereto shall take all reasonable steps which are
              necessary or reasonable to safeguard the secrecy and
              confidentiality of, and proprietary rights to, the Confidential
              Information disclosed or provided by the other Party, and shall
              not disclose the foregoing to any third party (other than any
              employee, agent, director, officer, consultant or contractor
              and on a "need to know" basis under suitable agreements of
              confidentiality with such parties) or use the same for purposes
              other than those set forth herein.


                                       -12-

        8.1.1 Each Party shall make no use whatsoever, directly or
              indirectly, of any Confidential Information of the other Party,
              except as required in connection with the performance of its
              obligations under this Agreement and in accordance with its
              terms.

        8.1.2 Upon either Party's request at any time and for any reason,
              the other Party shall immediately deliver to the Party so
              requesting all materials (including all copies) in its
              possession which contain Confidential Information of that Party.

          8.2 CONFIDENTIALITY WITH RESPECT TO THE TRC AND THE MDC.
              Confidential Information of a Party may be (and in certain
              circumstances must be) disclosed by the Party to the TRC or the
              MDC. The employees designated as members of the TRC and the MDC
              may share with their employers any and all information,
              including Confidential Information, disclosed to the TRC or the
              MDC; provided, however, that the requirements regarding
              Confidential Information set forth in Section 8.1 above will be
              observed by the members of the TRC and the MDC, the Parties and
              their employees with respect to Confidential Information
              disclosed by either Party to the TRC or the MDC.

          8.3 INTELLECTUAL PROPERTY. All inventions, development,
              improvements, patents, patent applications, trade secrets,
              processes, concepts, uses, know how, software applications,
              designs, works of authorship, algorithms, lists, marketing and
              business plans and other work product and intellectual property
              (collectively, "Intellectual Property") relating to C1 Software
              shall be the sole property of C1. . At any time or from time to
              time on and after the date of this Agreement, PwC shall at the
              request of C1 (i) deliver to C1 such records, data or other
              documents consistent with the provisions of this Agreement, and
              (ii) execute, and deliver or cause to be delivered, all such
              assignments, consents, documents or further instruments of
              transfer or license, and (iii) take or cause to be taken all
              such other actions, as C1 may reasonably deem necessary or
              desirable in order for C1 to obtain the full benefits of this
              Agreement and the transactions contemplated hereby. C1 shall,
              for any Intellectual Property relating to C1 Software owned by
              it and not by PwC provide to PwC a temporary, limited,
              non-exclusive, non-transferable license co-extensive with the
              term of this Agreement to use any and all such Intellectual
              Property solely for the purposes set forth in this Agreement
              (i.e., demonstration, internal training and support purposes).

          8.4 DATA COLLECTION. C1 and PwC may each compile for its own use and
              purposes, and shall have exclusive use and ownership of, any
              captured cost data or other information. Any such statistical
              data or information compiled by either C1 or PwC shall be its
              sole property, and it may use, sell or distribute such data or
              information for any purposes not prohibited by this Agreement
              or any other agreement.

          8.5 LICENSE. Following the execution of this Agreement, PwC, on
              behalf of PwC's Business Process Outsourcing service line and
              C1 shall negotiate in good faith regarding a license to

                       infringement of any patent, copyright or trade secret

                                   EXCLUSIVITY

Section 5.1. PEOPLESOFT EXCLUSIVITY. For a period commencing on the Effective
Date and ending on January 1, 2001, PeopleSoft shall not enter into an agreement
with Commerce One Specified Companies to Distribute or develop products similar
to the BuySite Products, the MarketSite Services and the associated software.
PeopleSoft shall use the MarketSite Services as its exclusive MRO Portals and
PeopleSoft shall not Distribute or develop any other hosted MRO Portals or enter
into any agreement with any third party with respect to any MRO Portal during
the period of this exclusivity. For the term of this Agreement, PeopleSoft shall
not provide a Source Code or Object Code license to the BuySite Products to a
Commerce One Specified Company. If, at any time commencing on the Effective Date
and ending on January 1, 2001 , PeopleSoft is in breach of the exclusivity
provisions of this Section 5.1 or assigns this Agreement through operation of
law, merger or acquisition of all or substantially all of its assets to a
Commerce One Specified Company, without limiting any other rights or remedies of
Commerce One, Commerce One shall be entitled to change the exclusivity set forth
in Sections 5.1 (a) and 5.3 below to non-exclusive by providing PeopleSoft with
written notice thereof. Nothing in this Section 5.1 shall be construed as
terminating this Agreement or the licenses granted herein.

     (a) PEOPLESOFT EXCLUSIVE ACCOUNTS. During the term of the Agreement and
subject to Section 5.3(a) and (b) below, PeopleSoft shall have the sole and
exclusive right, (except as to Grandfathered Resellers) to market and Distribute
the Products to the PeopleSoft Named Accounts other than PeopleSoft Named
Accounts within the Telco Industry.

Section 5.2. PEOPLESOFT MINIMUMS. Commencing on the Effective Date, and subject
to the potential extended period under Section 5.6 below, PeopleSoft shall enter
into licenses for the Products either directly or indirectly through
Distributors, with the projected cumulative sales targets set forth on
Attachment I (the "Minimum Targets"). For the purpose of this Section 5.2, any
license entered into by PeopleSoft or Commerce One with a Commerce One Named
Account pursuant to Section 5.3(a) below shall be considered a license by
PeopleSoft for the purpose of calculating the Total Customers as defined in
Attachment B. In the event that the Total Customers are not, at a minimum, equal
to the cumulative Minimum Target for any two consecutive calendar quarters,
Commerce One shall be entitled to demand and receive a change to the grant of
exclusivity set forth in Section 5.1(a) above to non-exclusive by written notice
to PeopleSoft; provided, however, that PeopleSoft shall first have the
opportunity to cure the possible loss of exclusivity as follows:


                                      -7-
<PAGE>

     If PeopleSoft does not meet the cumulative Minimum Target as of the end of
any two consecutive calendar quarters, PeopleSoft may, by the thirtieth (30th)
day ("Cure Date") of the calendar quarter immediately following the second
consecutive calendar quarter in which the cumulative Minimum Target was missed
(the "Cure Quarter"), pay a prepaid nonrefundable royalty creditable against
future licenses entered into by PeopleSoft in an amount equal to the average
PeopleSoft Net Fees received per End User for licenses entered into (not
including access agreements to MarketSite Services) by PeopleSoft for the twelve
(12) months preceding the beginning of the Cure Quarter, multiplied by "X",
where "X" is the Minimum Target as of the expiration of the second consecutive
calendar quarter, less the actual number of Total Customers licensed or sold
access to MarketSite Services, as applicable, as of the expiration of the second
consecutive calendar quarter ("Cure Cost"). It is understood and agreed that if
at the end of the Cure Quarter, PeopleSoft has entered into sufficient licenses
or access agreements to meet the Minimum Target as of end of the Cure Quarter
and paid the Cure Cost to Commerce One, then PeopleSoft shall be entitled to
retain the right of exclusivity under Section 5.1 above.

     By way of numerical example only, if, the Minimum Target for the tenth
(10th), eleventh (11th) and twelfth (12th) quarters are ninety-five (95), one
hundred and five (105) and one hundred and twenty (120) licenses or access
agreements for MarketSite Services, respectively, and the average PeopleSoft Net
Fees received per End User for licenses (but not including access agreements for
MarketSite Services) over the twelve (12) months prior to the beginning of the
Cure Quarter is equal to $500,000 ("X" = $500,000); and, PeopleSoft does not
meet the cumulative Minimum Target in the tenth (10th) quarter and enters into
only one hundred (100) licenses or access agreements to MarketSite Services by
the end of the eleventh (11th) quarter ("Total Customer" as defined in Section
14 of Attachment B herein), PeopleSoft will have missed the cumulative Minimum
Target for two (2) consecutive calendar quarters. The Cure Cost shall be equal
to the product obtained by multiplying $500,000 by five (5) (where five shall
have been calculated by subtracting the Total Customers at the end of the
eleventh quarter (100) from the cumulative Minimum Target as of the end of the
eleventh quarter (105)), or $2,500,000. If at the end of the twelfth quarter,
PeopleSoft shall have met the Minimum Target (120) and paid the Cure Cost of
$2,500,000, then PeopleSoft shall continue to retain its exclusivity.

     Section 5.3. COMMERCE ONE EXCLUSIVITY. For a period commencing on the
Effective Date and ending on January 1, 2001, Commerce One shall not enter into
an agreement with PeopleSoft Specified Companies to Distribute, sell or develop
products similar to the Products or MarketSite Services. Notwithstanding the
foregoing, Commerce One may enter into an Agreement with SAP only for the
purpose of becoming ISV certified and with Oracle for the purpose of database
development. If, at any time during the eighteen (18) months from the Effective
Date, Commerce One is in breach of the exclusivity provisions of this Section
5.3 or assigns this Agreement through operation of law, merger or acquisition of
all or substantially all of its assets to a Specified Company, without limiting
any other rights or remedies of PeopleSoft, PeopleSoft shall be entitled to
change the exclusivity set forth in Section 5.1 above or 5.3(a) below to
non-exclusive by providing Commerce One with written notice thereof. Nothing in
this Section 5.3 shall be construed as terminating this Agreement or the
licenses granted herein.


                                      -8-
<PAGE>

(a) COMMERCE ONE EXCLUSIVE ACCOUNT. Notwithstanding Section 5.1(a)
above, for a period of three (3) months after the Effective Date, Commerce One
shall have the exclusive right to Distribute the Products to the Commerce One
Named Accounts. In the event any of the Commerce One Named Accounts enters into
a license during such three (3) month period, such license may be between either
Commerce One or PeopleSoft and such individual Commerce One Named Account. Such
Commerce One Named Account shall pay fees to either Commerce One or PeopleSoft,
who shall then allocate the fees as set forth in Attachment B. Nothing in this
Section shall prohibit or discourage PeopleSoft from cooperatively engaging with
Commerce One with respect to Commerce One Named Accounts.

     (b) COMMERCE ONE EXCLUSIVE ACCOUNT. Notwithstanding Section 5.1 (a) above,
for a period of six (6) months after the Effective Date, Commerce One shall have
the exclusive right to market and Distribute the BuySite Products to the Telco
Named Accounts.

     (c) TELCO NAMED ACCOUNTS. From the Effective Date, PeopleSoft has a
non-exclusive right to Distribute the Products to the Telco Industry, excluding
the Telco Named Accounts. Commencing at the beginning of the seventh (7th)
month after the Effective Date, PeopleSoft shall be at liberty to Distribute to
the Telco Named Accounts.

     Section 5.4. LIMITED RIGHT TO WORK WITH SPECIFIED COMPANIES FOR END USER
CUSTOMER-REQUESTED IMPLEMENTATIONS.

     (a) The parties contemplate that only on a rare case-by-case basis both
parties may, due to an insistent End User customer request, need to work on such
End User-requested implementations with respect to Specified Company's products
and each party may, for such rare cases, provide services to such End User
notwithstanding the provisions of Sections 5.1 and 5.3. Prior to undertaking or
so agreeing to such an implementation effort, the requested party must first use
all reasonable efforts to direct the customer to an external independent third
party implementor to conduct the work for the End User. The parties shall also
use all reasonable efforts, primarily expected to be conducted through their
alliance personnel, to provide advance written notice (which shall include by
electronic mail) of at least five (5) business days to the other of a situation
whereby the requested party has attempted and failed to persuade the End User to
use an independent third party implementor and that the party is considering
entering into an End User agreement to provide the future direct implementation
services to the End User for the Specified Company product.

(b) The intent of this Section is that implementations for a
Specified Company conducted by the Parties shall be the rare exception rather
than the rule, and in the event such End User requested implementations occur on
at least two occasions within any six month period, the Parties acknowledge that
this is cause for concern and therefore the Parties' executive liaisons will
promptly have face-to-face meeting(s) to discuss this issue to resolve the issue
to their mutual satisfaction.

exclusivity shall be extended through September 30, 2001, and all Minimum
Targets as set forth in Section 5.2 shall be adjusted forward one quarter
beginning with the Minimum Target of sixty (60) at the end of the third
calendar quarter of 2001.

Section 5.7. LIMIT TO EXCLUSIVITY. Nothing in this Agreement shall prevent
PeopleSoft from entering into Agreements with third parties to integrate any
product or service content into the PeopleSoft Products.

Section 5.8. GOVERNMENT PROCUREMENT SOLUTION. In the event PeopleSoft elects to
move forward with a government procurement solution, PeopleSoft grants to
Commerce One a right to negotiate with regard to partnering to provide a

Section 6.8. COMMERCE ONE MOST FAVORED CUSTOMER PRICING. Commerce One shall
provide PeopleSoft with equally favorable pricing on MarketSite Direct Services

distributor at a similar level of distribution respecting similar MarketSite
Direct Services during such calendar year provided, that PeopleSoft's actual
purchases of MarketSite Direct Services during such calendar year are under
substantially equivalent terms and conditions as the purchases by such other
customer or distributor; and PeopleSoft's actual purchases of MarketSite Direct
Services are intended for sale in the same country or geographic region or
vertical market during such calendar year. In the event Commerce One is in
breach of the foregoing, MarketSite Direct Services pricing will be reduced by
Commerce One to PeopleSoft to equal the lower prices and will apply to
PeopleSoft purchases of MarketSite Direct Services from the date lower prices
were charged to such other customers or distributors by Commerce One. In
addition, if PeopleSoft took delivery of and paid for MarketSite Direct Services
while Commerce One was in breach of the foregoing representation, appropriate
credits toward the purchase of MarketSite Direct Services or refunds, at
PeopleSoft's option, shall be issued by Commerce One to PeopleSoft, the amount
of which shall reflect the differences in the prices for MarketSite Direct
Services that were actually charged to PeopleSoft and the prices for MarketSite
Direct Services which should have been charged to PeopleSoft if Commerce One had
complied with the foregoing representation.

time which is reasonably acceptable to Commerce One, Commerce One shall permit

provisions contained in this Section 6.8.

except in the event that it is determined, as a result of such review, that
Commerce One was not in compliance with the representations and other provisions
contained in this Section 6.8. Commerce One shall then reimburse PeopleSoft for
the reasonable costs PeopleSoft incurred in connection with such review,
including the fees paid to such certified public accountant. If the results of
such audit establish that the prices charged PeopleSoft are higher than the
prices Commerce One charges to any other


                                      -13-
<PAGE>

unaffiliated customer or distributor as described above by more than five

               the ability to dial-in to the Equipment on which the Software is
               operating and to obtain the same access to the Equipment as those
               of Customer's employees having the highest privilege or clearance
               level. C1 will inform Customer of the specifications of the modem
               equipment and associated software needed, and Customer will be
               responsible for the costs and use of said equipment.

          (b)  Customer shall document and promptly report all errors or
               malfunctions of the Software to C1. Customer shall take all steps
               necessary to carry out procedures for the rectification of errors
               or malfunctions within a reasonable time after such procedures
               have been received from C1. Customer shall maintain a current
               backup copy of all programs and data. Customer shall properly
               train its personnel in the Use and application of the Software
               and the Equipment on which it is used.

     5.7  MAINTENANCE FEE. The Maintenance Fee for each calendar year of
          Maintenance and Support will be fifteen percent (15%) of the list

          Maintenance Fees are included as part of the initial license fees as
          described in Schedule A. The Maintenance Fee is due and payable in
          full in advance within thirty (30) days after the date of delivery of
          the Software. Any amounts not paid within thirty (30) days will be
          subject to interest of 1% per month, which interest will be
          immediately due and payable. Each calendar year, the Maintenance Fee
          may be modified by C1 by written notice to Customer at least thirty
          (30) days prior to the end of the then-current term. In the event of a
          modification of the Maintenance Fee, Customer may discontinue
          Maintenance and Support. If Customer elects not to renew Maintenance
          and Support, Customer may re-enroll only upon payment of the annual
          Maintenance Fee for the coming year and ___ percent (___%) of all
          Maintenance Fees that would have been paid had Customer not terminated
          Maintenance and Support, which entitles Customer to all Updates and
          Releases of the Software which have been released during the same

          party on account of any loss or damage resulting from any delay or
          failure to perform all or any part of this Agreement if such delay or


                                      -7-
<PAGE>

          failure is caused, in whole or in part, by events, occurrences, or
          causes beyond the control and without negligence of the parties. Such
          events, occurrences, or causes will include, without limitation, acts
          of God, strikes, lockouts, riots, acts of war, earthquakes, fire and
          explosions, but the inability to meet financial obligations is
          expressly excluded.

     12.2 WAIVER. Any waiver of the provisions of this Agreement or of a party's
          rights or remedies under this Agreement must be in writing to be
          effective. Failure, neglect, or delay by a party to enforce the
          provisions of this Agreement or its rights or remedies at any time,
          will not be construed and will not be deemed to be a waiver of such
          party's rights under this Agreement and will not in any way affect the
          validity of the whole or any part of this Agreement or prejudice such
          party's right to take subsequent action. Except as expressly stated in
          this Agreement, no exercise or enforcement by either party of any
          right or remedy under this Agreement will preclude the enforcement by
          such party of any other right or remedy under this Agreement or that
          such party is entitled by law to enforce.

     12.3 SEVERABILITY. If any term, condition, or provision in this Agreement
          is found to be invalid, unlawful or unenforceable to any extent, the
          parties shall endeavor in good faith to agree to such amendments that
          will preserve, as far as possible, the intentions expressed in this
          Agreement. If the parties fail to agree on such an amendment, such
          invalid term, condition or provision will be severed from the
          remaining terms, conditions and provisions, which will continue to be
          valid and enforceable to the fullest extent permitted by law.

     12.4 ENTIRE AGREEMENT. This Agreement (including the Schedules and any
          addenda hereto signed by both parties) contains the entire agreement
          of the parties with respect to the subject matter of this Agreement
          and supersedes all previous communications, representations,
          understandings and agreements, either oral or written, between the
          parties with respect to said subject matter. This Agreement may not be
          amended, except by a writing signed by both parties.

     12.5 STANDARD TERMS OF CUSTOMER. No terms, provisions or conditions of any
          purchase order, acknowledgement or other business form that Customer
          may use in connection with the acquisition or licensing of the
          Software will have any effect on the rights, duties or obligations of
          the parties under, or otherwise modify, this Agreement, regardless of
          any failure of C1 to object to such terms, provisions or conditions.

     12.6 EXPORT OF SOFTWARE. Customer may not export or re-export the Software
          without the prior written consent of C1 and without the appropriate
          United States and foreign government licenses.

     12.7 PUBLIC ANNOUNCEMENTS. Customer acknowledges that C1 may desire to use
          its name in press releases, product brochures and financial reports
          indicating that Customer is a customer of C1, and Customer agrees that
          C1 may use its name in such a manner.

     12.8 COUNTERPARTS. This Agreement may be executed in counterparts, each of
          which so executed will be deemed to be an original and such
          counterparts together will constitute one and the same agreement.

     12.9 APPLICABLE LAW; JURISDICTION. This Agreement will be interpreted and
          construed in accordance with the laws of the State of California and
          the United States of America, without regard to conflict of law
          principles. All disputes arising out of this Agreement shall be
          subject to the exclusive jurisdiction and venue of the state and
          federal courts of Santa Clara County, California, and the parties
          consent to the exclusive and personal jurisdiction of these courts.

    12.10 HEADINGS. Section and Schedule headings are for ease of reference
          only and do not form part of this Agreement.

    12.11 NON-SOLICITATION. Customer acknowledges and agrees that the employees
          and consultants of C1 who perform the Maintenance and Support Services
          or other services are a valuable asset to C1 and are


                                      -8-
<PAGE>

          difficult to replace. Accordingly, Customer agrees that, for a
          period of twelve (12) months after the completion of the
          Maintenance and Support Services or other services, it will not
          offer employment as an employee, independent contractor, or
          consultant to any C1 employee or consultant who performs any of the
          Maintenance and Support Services or other services.

IN WITNESS WHEREOF, the parties have executed this Agreement.

                            OEM MAINTENANCE AND SUPPORT
                            ---------------------------

     1.   MAINTENANCE/MINOR UPDATES.  In consideration of the Maintenance and
Support fee set forth in Attachment B, Commerce One will provide to
PeopleSoft any Minor Updates made generally available during the five (5)
year term of maintenance and support. PeopleSoft and not Commerce One will be
responsible for providing Minor Updates to its PeopleSoft Customers,
Distributors and End Users. The expenses of any such distribution will be
paid by PeopleSoft. PeopleSoft and Commerce One will favorably consider
electronic or alternative dissemination methods of such Minor Updates to the
extent consistent with policies of both companies. PeopleSoft and Commerce
One agree to discuss monthly support issues and processes.

     2.   TECHNICAL SUPPORT.  In consideration of the Maintenance and Support
fee set forth in Attachment B, Commerce One will provide PeopleSoft with
Commerce One's backend technical support services, as further described
herein.

          a.   BACK-END SUPPORT.  Commerce One will provide back-end support
to PeopleSoft for Program Errors not resolved by PeopleSoft pursuant to
PeopleSoft's support policies and in accordance with subparagraph (b) below.
This support includes efforts to identify defective source code and to
provide corrections, workarounds and/or patches to correct Program Errors.
Commerce One will provide PeopleSoft with a telephone number and an e-mail
address which PeopleSoft may use to report Program Errors during Commerce
One's standard support hours. For priority 1 or 2 failures, PeopleSoft agrees
to notify Commerce One via a method to be determined as mutually agreed
between the parties.  The parties agree to have designated members of each
party's support staff meet on a regular basis to address support issues as
they arrive with respect to support activities and to manage, with a view to
continuously improve, the support relationship and process. Each party will
identify one (1) member of its customer support staff and an alternate to act
as the primary technical liaisons responsible for all communications with the
other party's technical support representatives. Such liaisons will have
sufficient technical expertise, training and/or experience for PeopleSoft to
perform its obligations hereunder. Notification will be in writing and/or
e-mail to Commerce One. PeopleSoft may substitute contacts at any time.

     Commerce One will make reasonable efforts to correct significant Program
Errors that PeopleSoft identifies, classifies and reports to Commerce One and
that Commerce One substantiates. Commerce One may reclassify Program Errors
if it reasonably believes that PeopleSoft's classification is incorrect.
PeopleSoft will provide sufficient information to enable Commerce One to
duplicate the Program Error before Commerce One's response obligations will
commence. Commerce One will not be required to correct any Program Error
caused by (a) PeopleSoft's incorporation or attachment of a feature, program,
or device to the BuySite Products, or any part thereof; (b) any
nonconformance caused by accident, transportation, neglect, misuse,
alteration, modification, or enhancement of the BuySite Products; (c) the
failure to provide a suitable installation environment; (d) use of the
BuySite Products for other than the specific purpose for


<PAGE>

which the BuySite Products are designed; (e) use of the BuySite Products on
any systems other than the specified hardware platform for such BuySite
Products; (f) PeopleSoft's use of defective media or defective duplication of
the BuySite Products; or (g) PeopleSoft's failure to incorporate any Minor
Update previously released by Commerce One which corrects such Program Error.

     Provided Program Error reports are received by Commerce One during
Commerce One's standard support hours, Commerce One will use its best
commercial efforts to communicate with PeopleSoft about the Program Error via
telephone or e-mail within the targeted response times which shall be
determined by mutual agreement of the parties.  The parties will use
reasonable efforts to ensure the targeted response times will meet and
implement the PeopleSoft standards and current best practices.

     Commerce One will use reasonable commercial efforts to resolve each
significant Program Error by providing either a reasonable workaround, an
object code patch, or a specific action plan for how

     Commerce One will address the problem and an estimate of how long it
will take to rectify the defect. Commerce One reserves the right to charge
PeopleSoft additional fees at its then-standard rates for services performed
in connection with reported Program Errors which are later determined to have
been due to hardware or software not supplied by Commerce One.
Notwithstanding the foregoing, Commerce One has no obligation to perform
services in connection with (i) Program Errors resulting from hardware or
software not supplied by Commerce One; (ii) which occur in the BuySite
Product release which is not the then-current supported releases; or (iii)
which are not aligned with the PeopleSoft support policy.

     b.   FRONT-LINE SUPPORT.  PeopleSoft, and not Commerce One, will provide
front-line, or first and second level, technical support to its PeopleSoft
Customers, Distributors and End Users. Such support includes call receipt,
call screening, installation assistance, problem identification and
diagnosis, efforts to create a repeatable demonstration of the Program Error
and, if applicable, the distribution of any defective media or Minor Updates.
PeopleSoft agrees that any documentation Distributed by PeopleSoft will
clearly and conspicuously state that End Users should call PeopleSoft for
technical support for the BuySite Products. Commerce One will have no
obligation to furnish any assistance, information or documentation with
respect to the BuySite Products, to any PeopleSoft Customer, Distributor or
End User. If Commerce One customer support representatives are being
contacted by a significant number of Distributors or End Users then, upon
Commerce One's request, PeopleSoft and Commerce One will cooperate to
minimize such contact.

PEOPLESOFT PRODUCT

The PeopleSoft Product shall offer web-based procurement capabilities that

Product Source Code or Derivative Works thereof.  The PeopleSoft product may
also be developed without any such BuySite Product Source Code.  PeopleSoft
shall be entirely free to determine the features and functionality of the
PeopleSoft Product using internal resources, contracted resources or through
acquisition either in whole or in part.

For greater clarity, nothing in this definition of the PeopleSoft Product
shall include any and all other PeopleSoft products developed by or on behalf
of PeopleSoft including but not limited to PeopleSoft ERP products, analytic
products and other PSBN products not explicitly defined above.
