                           SENIOR MANAGEMENT AGREEMENT

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

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

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

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

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

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

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

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



<PAGE>

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

         NOW, THEREFORE, the parties hereto agree as follows:

                     PROVISIONS RELATING TO EXECUTIVE STOCK

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

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

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

         4.   REPURCHASE OPTION.

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

                                                            Percentage of Unvested Stock to be
              Date                                          Repurchased at Original Cost

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

</TABLE>

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

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

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


                                      -3-
<PAGE>

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

         6.   ADDITIONAL RESTRICTIONS ON TRANSFER OF EXECUTIVE STOCK.

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

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

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

                        PROVISIONS RELATING TO EMPLOYMENT

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

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


                                      -4-
<PAGE>

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

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

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

         8.   CONFIDENTIAL INFORMATION.

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


                                      -5-
<PAGE>

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

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

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

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

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


                                      -6-
<PAGE>

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

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

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

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

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


                                      -7-
<PAGE>

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

or such other address or to the attention of such other person as the recipient

         12.  GENERAL PROVISIONS.

              (a)  EXPENSES. The Company shall pay all legal, accounting and
other expenses incurred in connection with the negotiation and execution of
this Agreement and the consummation of the transactions contemplated by this
Agreement.

              (b)  TRANSFERS IN VIOLATION OF AGREEMENT. Any Transfer or
attempted Transfer of any Executive Stock in violation of any provision of
this Agreement shall be void, and the Parent shall not record such Transfer
on its books or treat any purported transferee of such Executive Stock as the
owner of such stock for any purpose.

              (c)  AMENDMENT OF SUBSCRIPTION AGREEMENT. Notwithstanding
anything in this Agreement to the contrary, Section 12(c) of the AppNet
Senior Management Agreement shall remain in full force and effect with
respect to the deletion of Sections 1(c), 2(d), 3(m), 3(n), 4, 6, 7(b) and

              (d)  SEVERABILITY. Whenever possible, each provision of this
Agreement will be interpreted in such manner as to be effective and valid
under applicable law, but if any provision of this Agreement is held to be
invalid, illegal or unenforceable in any respect under any applicable law or
rule in any jurisdiction, such invalidity, illegality or unenforceability
will not affect any other provision or any other jurisdiction, but this
Agreement will be reformed, construed and enforced in such jurisdiction as if
such invalid, illegal or unenforceable provision had never been contained
herein.

              (e)  COMPLETE AGREEMENT. This Agreement, those documents
expressly referred to herein and other documents of even date herewith embody
the complete agreement and understanding among the parties and supersede and
preempt any prior understandings, agreements or representations by or among
the parties, written or oral, which may have related to the subject matter
hereof in any way, including the AppNet Senior Management Agreement (except
as otherwise provided herein), which is hereby terminated in all respects and
is superceded and preempted by the provisions of this Agreement as of the
Effective Time; and the parties hereby agree and acknowledge that any rights
or obligations under the AppNet Senior Management Agreement shall also be
terminated and shall be superceded by the rights and obligations under this
Agreement upon the Effective Time.

              (f)  COUNTERPARTS. This Agreement may be executed in separate
counterparts, each of which is deemed to be an original and all of which
taken together constitute one and the same agreement.

              (g) SUCCESSORS AND ASSIGNS. Except as otherwise provided
herein, this Agreement shall bind and inure to the benefit of and be
enforceable by Executive, the Company, the Parent and their respective
successors and assigns (including subsequent holders of Executive Stock);
provided that the rights and obligations of Executive under this Agreement
shall not be assignable except in connection with a permitted transfer of
Executive Stock hereunder.

              (h)  CHOICE OF LAW. The corporate law of the State of Delaware
will govern all questions concerning the relative rights of the Parent and
its stockholders. All other questions concerning the construction, validity
and interpretation of this Agreement and the exhibits hereto will be governed
by and construed in accordance with the internal laws of the State of
Maryland, without giving effect to any choice of law or conflict of law
provision or rule (whether of the State of Maryland or any other
jurisdiction) that would cause the application of the laws of any
jurisdiction other than the State of Maryland.

              (i)  REMEDIES. Each of the parties to this Agreement will be
entitled to enforce its rights under this Agreement specifically, to recover
damages and costs (including attorney's fees) caused by any breach of any
provision of this Agreement and to exercise all other rights existing in its
favor. The parties hereto agree and acknowledge that money damages may not be
an adequate remedy for any breach of the provisions of this Agreement and
that any party may in its sole discretion apply to any court of law or equity
of competent jurisdiction (without posting any bond or deposit) for specific
performance and/or other injunctive relief in order to enforce or prevent any
violations of the provisions of this Agreement.

              (j)  AMENDMENT AND WAIVER. The provisions of this Agreement may
be amended and waived only with the prior written consent of the Parent and
Executive.

              (k)  BUSINESS DAYS. If any time period for giving notice or
taking action hereunder expires on a day which is a Saturday, Sunday or
holiday in the state in which the Parent's chief executive office is located,
the time period shall be automatically extended to the business day
immediately following Saturday, Sunday or holiday.

              (l)  TERMINATION. This Agreement (except for the provisions of
Section 7) shall survive a Separation and shall remain in full force and
effect after such Separation.

              (m)  ADJUSTMENTS OF NUMBERS. All numbers set forth herein which
refer to share prices or amounts will be appropriately adjusted to reflect
stock splits, stock dividends, combinations of shares and other
recapitalizations affecting the subject class of stock.

         IMPORTANT: THIS AGREEMENT CONTAINS VERY IMPORTANT TERMS GOVERNING YOUR
EMPLOYMENT WITH THE PARENT. SECTION 9 CONTAINS PROVISIONS WHICH AFFECT YOUR
ABILITY TO TAKE CERTAIN ACTIONS FOLLOWING THE TERMINATION OF YOUR EMPLOYMENT.
YOU SHOULD FEEL FREE TO SEEK ADVICE FROM YOUR ATTORNEY REGARDING ANY MATTER
