Jones' purchase of the Property, and Jones acknowledges that the Company is
relying on such representations in guarantying the Loan:

Company the security interest in the Property evidenced by the Deed of Trust.

good faith that a title issue exists, Jones shall furnish evidence reasonably

Company a valid first-priority lien on the Property, Jones shall promptly take
all action necessary to remove such defects and to obtain such consent and grant
(or cause to be granted) and perfect such lien on the Property. Failure of the

sums due hereunder, under the Indemnity Agreement, or under any other document
executed by Jones in connection herewith in accordance with the terms and
conditions of this Agreement, the Indemnity Agreement or such other document.

written instrument signed by the party against whom enforcement of any such
amendment, waiver, discharge, or termination is sought. No waiver of any
provision of this Agreement or any other Loan Document shall be effective unless

remedies available under any other document or instrument, at law or in equity.

acknowledges that this Agreement does not modify Employee's at-will status at
the Company and does not constitute an employment agreement or a promise by the
Company to continue Jones' employment. Either the Company or Jones may terminate
such employment relationship at any time, with or without cause.

hereunder shall be in writing and may be given by (a) personal delivery,

Company. All of the rights and/or duties of the Company under the Loan
Documents, or any of them, shall be freely assignable. Subject to the foregoing,

Exhibit A

FORM OF BOFA INDIVIDUAL LOAN AGREEMENT

    This Agreement dated as of August 22, 2001 is between Bank of America, N.A.
(the "Bank") and Dennis H. Jones (the "Borrower").

1.  TERM LOAN AMOUNT AND TERMS

1.1 Loan Amount.  The Bank agrees to provide a term loan to the Borrower in the
amount of Three Million Five Hundred Thousand and 00/100 Dollars ($3,500,000.00)
(the "Commitment").

1.2 Availability Period.  The loan is available in one disbursement from the
Bank between the date of this Agreement and August 31, 2001 unless the Borrower
is in default.

1.3 Interest Rate.

(a)The interest rate is a rate per year equal to the Wall Street Journal LIBOR
Rate plus 2.00 percentage points.

(b)The interest rate will be adjusted on the 8th day of every August (the
"Adjustment Date") and remain fixed until the next Adjustment Date. If the
Adjustment Date in any particular month would otherwise fall on a day that is
not a banking day, the Adjustment Date for that particular month will be the
first banking day immediately following thereafter.

(c)The Wall Street Journal LIBOR Rate is a rate of interest equal to the twelve
month London interbank offered rate as published in the "Money Rates" section of
The Wall Street Journal on the banking day immediately preceding the Adjustment
Date (or, if such source is not available, such alternate source as determined
by the Bank), as adjusted from time to time in the Bank's sole discretion for
reserve requirements, deposit insurance assessment rates and other regulatory
costs.

1.4 Repayment Terms.

(a)The Borrower will pay all accrued but unpaid interest on the first day of
each month and upon payment in full of the principal of this loan.

(b)The Borrower will repay in full any principal, interest or other outstanding
charges on the loan no later than August 7, 2005.

1.5 Prepayments.

(a)The Borrower may prepay the loan in full or in part at any time in an amount
not less than One Hundred Thousand and 00/100 Dollars ($100,000.00). The
Borrower will give the Bank irrevocable written notice of the Borrower's
intention to make the prepayment, specifying the date and amount of the
prepayment. The notice must be received by the Bank at least 5 banking days in
advance of the prepayment. The prepayment will be applied to the most remote
payment of principal due under this Agreement.

(b)Each prepayment, whether voluntary, by reason of acceleration or otherwise,
will be accompanied by the amount of accrued interest on the amount prepaid, and
the prepayment fee described below.

(c)The prepayment fee shall be in an amount sufficient to compensate the Bank
for any loss, cost or expense incurred by it as a result of the prepayment,
including any loss of anticipated profits and any loss or expense arising from
the liquidation or reemployment of funds obtained by it to maintain the loan or
from fees payable to terminate the deposits from which such funds were obtained.
The Borrower shall also pay any customary administrative fees charged by the
Bank in connection with the foregoing. For purposes of this paragraph, the Bank
shall be deemed to have

1

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

funded the loan by a matching deposit or other borrowing in the applicable
interbank market, whether or not the loan was in fact so funded.

2.  FEES AND EXPENSES

2.1 Fees

(a)Loan fee.  The Borrower agrees to pay a fee equal to 1% of the amount
disbursed. This fee is due on the date funds are advanced under this Agreement.

(b)Waiver Fee.  If the Bank, at its discretion, agrees to waive or amend any
terms of this Agreement, the Borrower will, at the Bank's option, pay the Bank a
fee for each waiver or amendment in an amount advised by the Bank at the time
the Borrower requests the waiver or amendment. Nothing in this paragraph shall
imply that the Bank is obligated to agree to any waiver or amendment requested
by the Borrower. The Bank may impose additional requirements as a condition to
any waiver or amendment.

(c)Late Fee.  To the extent permitted by law, the Borrower agrees to pay a late
fee in an amount not to exceed four percent (4%) of any installment that is more
than fifteen (15) days late. The imposition and payment of a late fee shall not
constitute a waiver of the Bank's rights with respect to the default.

2.2 Reimbursement Costs.

(a)The Borrower agrees to reimburse the Bank for any expenses it incurs in the
preparation of this Agreement and any agreement or instrument required by this
Agreement. Expenses include, but are not limited to, reasonable attorneys' fees,
including any allocated costs of the Bank's in-house counsel.

(b)The Borrower agrees to reimburse the Bank for the cost of periodic audits and
appraisals of the personal property collateral securing this Agreement, at such
intervals as the Bank may reasonably require. The audits and appraisals may be
performed by employees of the Bank or by independent appraisers.

3.  COLLATERAL

3.1 Lent Collateral.  The Borrower's obligations to the Bank under this
Agreement will be secured by personal property now owned or owned in the future
by Commerce One, Inc. as listed below. The collateral is further defined in
security agreement(s) executed by Commerce One, Inc.

(a)Bank of America, N.A. time deposits in an amount not less than Three Million
Five Hundred Thousand Dollars ($3,500,000).

4.  DISBURSEMENTS, PAYMENTS AND COSTS

4.1 Direct Debit.

(a)The Bank shall debit Commerce One, Inc.'s designated deposit account with the
Depository listed below (the "Designated Account") in the amount of each payment
of principal, interest and other fees and charges under this Agreement on the
date such payments become due.

 
 
   
  Depository Name:   Commerce One, Inc.   Address:   Bank of America
Dallas, TX75762   Routing Number:   111-000-012   Commerce One Inc.'s Deposit
Account Number:  375-161-7419   (A voided copy of a check on this account is
attached to this Agreement).

2

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

(b)Commerce One, Inc. authorizes the Bank to debit the Designated Account by no
later than the close of business on the dates payments become due. The ACH
debits shall be subject to the operating rules of the National Automated
Clearing House Association, as in effect from time to time.

(c)Commerce One, Inc. shall maintain sufficient funds in the Designated Account
on the dates the Bank enters debits authorized by this Agreement. If there are
insufficient funds in the Designated Account on the date the Bank enters any
debit authorized by this Agreement, such debit will be reversed.

(d)The Bank or Commerce One, Inc. may terminate this direct debit arrangement at
any time by notice in writing to the other party. Any such termination notice
shall be effective ten (10) days after its receipt; provided, however, that at
the Bank's discretion, any such termination notice shall be effective
immediately upon any default under this Agreement or for other reasonable cause.
In the event the Bank or Commerce One, Inc. terminates this direct debit
arrangement, Commerce one, Inc. shall commence, as of the date such termination
is effective, to make principal, interest and other payments in the funds and at
such office of the Bank as the Bank may from time to time select or as otherwise
provided in any agreement between the Bank and the Borrower.

(e)The Bank will initiate debits on the dates the payments become due. If a due
date does not fall on a banking day, the Bank will initiate debits on the first
banking day following the due date.

4.2 Banking Days.  Unless otherwise provided in this Agreement, a banking day is
a day other than a Saturday or a Sunday on which the Bank is open for business
in California. For amounts bearing interest at an offshore rate (if any), a
banking day is a day other than a Saturday or a Sunday on which the Bank is open
for business in California and dealing in offshore dollars. All payments and
disbursements which would be due on a day which is not a banking day will be due
on the next banking day. All payments received on a day which is not a banking
day will be applied to the credit on the next banking day.

4.3 Interest Calculation.  Except as otherwise stated in this Agreement, all
interest and fees, if any, will be computed on the basis of a 360-day year and
the actual number of days elapsed. This results in more interest or a higher fee
than if a 365-day year is used. Installments of principal which are not paid
when due under this Agreement shall continue to bear interest until paid.

4.4 Default Rate.  Upon the occurrence of any default under this Agreement,
principal amounts outstanding under this Agreement will at the option of the
Bank bear interest at a rate which is 4 percentage point(s) higher than the rate
of interest otherwise provided under this Agreement. This will not constitute a
waiver of any default.

5.  CONDITIONS

The Bank must receive any documents and other items it may reasonably require,
including but not limited to the following items, in form and content acceptable
to the Bank, before it is required to extend any credit to the Borrower under
this Agreement.

each guarantor of this Agreement and any instrument or agreement required under

INDEMNITY AGREEMENT
SECURED BY DEED OF TRUST

    THIS INDEMNITY AGREEMENT SECURED BY DEED OF TRUST ("Agreement") is entered
into as of the 22nd day of August, 2001, by and between COMMERCE ONE, INC., a
Delaware corporation (the "Company"), and DENNIS H. JONES ("Jones").

RECITALS

    A.  Jones is employed by the Company as its Vice Chairman and President.

    B.  Jones has purchased a residence at 8009 Horizons Court, Pleasanton,
California (the "Property") using Two Million Four Hundred Twenty-five Thousand
Dollars ($2,425,000) borrowed from the Company (the "Bridge Loan").

    C.  The Company and Jones desire that Bank of America, N.A. ("BofA") lend to
Jones the sum of up to Three Million Five Hundred Thousand Dollars
($3,500,000.00) to assist Jones in three distinct ways: (i) repaying the Bridge
Loan (which portion is referred to herein as the "Real Estate Loan"),
(ii) landscaping the Property and making interior improvements (the "Improvement
Loan") and (iii) incurring other expenses (the "Supplemental Loan") (all
together herein the "BofA Loan"), and bearing an initial interest rate of not
more than LIBOR plus two percent (2%).

    D.  The Company has agreed to guaranty the BofA Loan in accordance with the
terms of a separate agreement between BofA and the Company (the "Guaranty"), on
condition that Jones execute and deliver to the Company this Agreement, the Deed
of Trust (as hereinafter defined), and such other documents and instruments as
the Company may from time to time require to evidence and secure the obligations
of Jones under this Agreement (this Agreement, such Deed of Trust, and all such
other documents and instruments being referred to herein collectively as the
"Loan Documents").

AGREEMENT

    1.  BofA Loan Documents:  All documents and instruments evidencing or
securing the BofA Loan (the "BofA Loan Documents") shall be in form and
substance satisfactory to the Company. Jones shall not execute or deliver any
BofA Loan Documents without the prior written consent of the Company, in the
Company's sole and absolute discretion. In particular, but without limitation,
the promissory note or loan agreement (the "BofA Note") evidencing the BofA Loan
shall be in a principal amount not exceeding $3,500,000, the rate of interest
accruing on the principal amount of the BofA Note shall not exceed LIBOR plus
two percent (2%) per annum, the BofA Note shall mature not more than four
(4) years from the date thereof, and the BofA Loan shall not provide for any
additional advances of principal to Jones thereunder. After Jones has executed
and delivered BofA Loan Documents approved by the Company, as hereinabove
provided, the BofA Loan Documents shall not be amended or modified in any
respect, nor shall any term or condition thereof be waived, nor shall any
consent be granted thereunder, without in each instance first having obtained
the prior written consent of the Company, in the Company's sole and absolute
discretion. Each of the BofA Loan Documents shall expressly incorporate the
provisions of this paragraph.

    2.  Performance by Jones:  Jones shall pay and perform in a timely manner
all amounts and obligations of Jones under the BofA Loan Documents or otherwise
in connection with the BofA loan. Notwithstanding the foregoing sentence, on
condition that (i) Jones has otherwise paid and performed all obligations under
the BofA Loan Documents and otherwise in connection with the BofA Loan,
(ii) Jones has timely paid and performed all obligations under this Agreement,
the Deed of Trust (as hereinafter defined), the Employee Loan Agreement dated
the date hereof between Jones and the Company, and all other documents and
instruments from time to time executed and delivered by Jones to the Company in
connection with Jones' obligations under this Agreement (collectively, the
"Company Loan Documents"), and (iii) no Payment Event (as hereinafter defined)
has occurred hereunder, the Company shall pay BofA for the account of Jones the
regularly-scheduled payments of

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

interest only required under the BofA Note ("Regular Interest"). Upon the
occurrence, however, of any of the events described in the foregoing clauses
(i), (ii), or (iii), the Company shall thereafter have no obligation to make any
payments of Regular Interest, and Jones shall be solely responsible for payment
of all Regular Interest.

    3.  Indemnity:  Jones acknowledges that the Company is executing and
delivering the Guaranty as an accommodation only to Jones to facilitate Jones'
borrowing of the BofA Loan. Except as provided herein, Jones shall indemnity,
defend (with counsel reasonably satisfactory to the Company), protect and hold
harmless the Company from and against any and all Losses (including reasonable
attorneys' fees and expenses) arising from or relating in any manner to the BofA
Loan and/or the Property. In particular, but without limitation, Jones shall,
immediately upon demand, repay and reimburse the Company any and all amounts
from time to time paid by the Company under the Guaranty, including, without
limitation, all principal, interest (excepting only Regular Interest for which
the Company is responsible under Paragraph 2), late charges, and other costs
from time to time incurred by the Company under the Guaranty and/or the BofA
Loan Documents. All such amounts from time to time paid by the Company under the
Guaranty and/or the BofA Loan Documents shall bear interest, from the date(s) of
advance thereof until repaid in full, at the lesser of twelve percent (12%) per
annum or the maximum amount permitted by law. All repayments and reimbursements
required to be made hereunder shall be made by Jones free and clear of, and
without deduction for, any and all present and future taxes, levies, charges,
deductions and withholdings. Jones shall pay upon demand any stamp or other
taxes, levies or charges of any jurisdiction with respect to the execution,
delivery, performance and enforcement of this Agreement.

    4.  Payment Event:  Upon the occurrence of any Payment Event (as hereinafter
defined), Jones shall, immediately at Jones' sole cost and without any demand or
notice whatsoever, either (i) pay and satisfy in full the entire outstanding
amount of the BofA Loan, including all principal, interest, and other amounts
due thereunder, and cause the full and final release and termination of the
Guaranty and the return to the Company of any and all collateral securing the
Company's performance of the Guaranty, (ii) substitute such collateral, provide
such substitute guarantors, and take such other actions as may be required by
BofA and thereby obtain the full and final release and termination of the
Guaranty and the return to the Company of any and all collateral securing the
Company's performance of the Guaranty, or (iii) convey the Property to the
Company by grant deed subject only to those exceptions to title to which the
deed of trust is subject (with such conveyance of the Property releasing Jones
from any indemnity for Company claims related to impaired market value caused by
market factors), and repay the amount of the Supplemental Loan.

    5.  Security:  

    (a)  The Real Estate Loan.  The obligations of Jones as to the Real Estate
Loan and the Improvement Loan are secured by that certain Deed of Trust (the
"Deed of Trust") of even date herewith made by Jones, as trustor, to First
American Title Insurance Company, as trustee, for the benefit of the Company, as
beneficiary, which shall be recorded in the Official Records of the County of
Alameda, State of California, encumbering certain real property commonly known
as 8009 Horizons Court in the City of Pleasanton, County of Alameda, State of
California (the "Property"), described with particularity in the Deed of Trust,
which Jones intends to occupy as his principal place of residence. The Deed of
Trust provides, among other things, as follows:

"If the Trustor shall sell, convey, encumber, grant any lien upon, or otherwise
alienate the Property, or any part thereof, or any interest therein, or shall be
divested of their respective title or any interest therein in any manner or way,
whether voluntarily or involuntarily, without the written consent of the
Beneficiary being first had and obtained, in Beneficiary's sole and absolute
discretion, Beneficiary shall have the right, at its option, except as
prohibited by law, to declare an immediate "Payment Event" under the Indemnity
Agreement."

and instruments as the Company may request to document and collateralize the
Supplemental Loan.

    6.  Payment Event:  To the extent permitted by law, any of the following
events shall be a "Payment Event" under this Agreement, the Deed of Trust, and

    (b)  The occurrence of any breach or default in the performance of any
obligation of Jones contained in this Agreement, the Deed of Trust, any of the
other Company Loan Documents, or any other agreement now or hereafter entered
into by Jones, on the one hand, and the Company, on the other hand, with respect
to the Property (including, without limitation, any failure of Jones to repay,
reimburse, indemnify and hold harmless the Company as provided in Paragraph 3).

    (c)  The occurrence of any breach or default in the performance of any
obligation of Jones in any other deed of trust or other security instrument now
or hereafter encumbering the Property.

    (d)  Jones shall sell, convey, encumber, grant any lien upon, or otherwise
alienate the Property, or any part thereof, or any interest therein, or shall be
divested of his respective title or any interest therein in any manner or way,
whether voluntarily or involuntarily, without the written consent of the Company
being first had and obtained, in the Company's sole and absolute discretion.

    (e)  Any representation or warranty of Jones contained herein or any other
Company Loan Document or in any certificate or agreement entered into by Jones
for the benefit of the Company in connection herewith shall be false or
misleading in any material respect.

    (f)  Jones (i) admits in writing his inability to pay debts, (ii) make an
assignment for the benefit of creditors, (iii) file a voluntary petition in
bankruptcy, effect a plan or other arrangement with creditors, liquidate his
assets under arrangement with creditors, or liquidate his assets under court
supervision, (iv) have an involuntary petition in bankruptcy or receivership
filed against him that is not discharged within sixty (60) days after such
petition is filed, or (v) apply for or permit the appointment of a receiver or
trustee or custodian for any of his property or assets.

    (g)  Any involuntary lien, attachment or other encumbrance is imposed
against the Property and is not discharged within ten (10) days.

    (h)  The Deed of Trust is not promptly recorded against the Property or at
any time ceases to be a valid first priority lien on the Property.

    (i)  The occurrence of the ninetieth (90th) day following the termination of
Jones' employment with the Company for any reason, provided that, if such
termination is due to Jones' death, the Company shall not enforce its rights so
long as Jones' heirs, executors, or trustees shall fully cooperate with the
Company in listing the Property for sale to provide for the repayment of the
BofA Loan.

    7.  Jones' Representations:  Jones hereby makes the following
representations and warranties to the Company and acknowledges that the Company
is relying on such representations in making the loan:

    (a)  Jones shall at all times have good and marketable title to the Property
free and clear of any security interests, liens or encumbrances other than the
Deed of Trust in favor of the Company securing this Note.

    (b)  Each of the BofA Loan Documents and the Company Loan Documents has been
duly executed and delivered by Jones and constitute the legal, valid and binding
obligations of Jones enforceable against Jones in accordance with their
respective terms. The consent of no other

3

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

person or entity is required to execute, deliver and perform the BofA Loan
Documents or the Company Loan Documents or to grant to the Company the security
interest in the Property evidenced by the Deed of Trust.

    (c)  There are no actions, proceedings, claims, or disputes pending or, to
Jones' knowledge, threatened against or affecting Jones or the Property.

    8.  Jones' Additional Obligations:  Jones shall take any and all further
actions that may from time to time be required to ensure that the Deed of Trust
creates a valid first priority lien on the Property in favor of the Company as
security as provided herein. Upon request by the Company, but not more
frequently than once during any calendar year, Jones shall furnish evidence
reasonably satisfactory to the Company that: (i) Jones' has good and marketable
title to the Property free and clear of any liens or encumbrances other than the
Deed of Trust and those matters shown in the title insurance policy issued in
favor of the Company and insuring the Deed of Trust as of the close of escrow of
Jones' purchase of the Property; (ii) the consent of no other person or entity
is required to grant a first priority security interest in the Property to the
Company; (iii) the Deed of Trust is a first priority security interest in the
Property, and (iv) there are no other deeds of trust, mortgages or encumbrances
against the Property. If it should be hereafter determined that there are
defects against title or matters which could result in defects against title to
the Property, or that the consent of another person or entity is required to
grant to and perfect in the Company a valid first-priority lien on the Property,
Jones shall promptly take all action necessary to remove such defects and to
obtain such consent and grant (or cause to be granted) and perfect such lien on
the Property. Failure of the Deed of Trust to be a valid first lien against the
Property shall be deemed a Payment Event as aforesaid.

    9.  Distribution of BofA Loan Proceeds:  Jones covenants and warrants that
the proceeds of the BofA loan not used for repaying the Bridge Loan shall be
maintained in an insured bank account, and shall not be spent without the prior
written consent of the Company, and shall be promptly documented upon
disbursement.

    10.  Attorneys' Fees:  In the event of Jones' default or the occurrence of
any Payment Event hereunder Jones shall pay all costs of collection, including
reasonable attorneys' fees incurred by the holder hereof on account of such
collection, whether or not suit is filed hereon.

    11.  Waiver:  The waiver by the Company of any breach of or default under
any term, covenant or condition contained herein or in any other agreement
referred to above shall not be deemed to be a waiver of any subsequent breach of
or default under the same or any other such term, covenant or condition.

    12.  No Usury:  Anything in this Agreement to the contrary notwithstanding,
it is expressly stipulated and agreed that the intent of Jones and the Company
is to comply at all times with all usury and other laws relating to this
Agreement. If the laws of the State of California would now or hereafter render
usurious, or are revised, repealed or judicially interpreted so as to render
usurious, any amount called for under this Agreement, or contracted for, charged
or received with respect to this Agreement, or if any prepayment by Jones
results in Jones having paid any interest in excess of that permitted by law,
then it is Jones' and the Company's express intent that all excess amounts
theretofore collected by the Company be refunded to Jones, and the provisions of
this Agreement immediately be deemed reformed and the amounts therefor
collectible hereunder reduced, without the necessity of execution of any new
document, so as to comply with the then applicable law, but so as to permit the
recovery of the fullest amount otherwise called for hereunder.

    13.  General Provisions:  This Agreement shall be governed by and construed
in accordance with the laws of the State of California. To the extent
applicable, Jones hereby waives presentment for payment, protest and demand,
notice of protest, demand and dishonor and nonpayment, and consent that the
Company may extend the time for payment or otherwise modify the terms of payment
or any

4

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

part of the whole of the debts created by this Agreement, at the request of any
person liable hereon, and such consent shall not alter or diminish the liability
of any person. Jones hereby waives the defense of the statute of limitations in
any action on this Note to the extent permitted by law. Time is of the essence
of this Agreement, the Deed of Trust and any other document executed by Jones in
connection therewith. Liability hereunder shall be joint and several both
between Jones and among all other persons and entities now or hereafter liable
for all or any part of this Agreement.

    14.  Notices:  All notices and other communications required or permitted
