        Milestone Shares and thereafter shall be held and released pursuant to
        the terms of Article IV and shall be the GM Milestone Shares for the

Agreement, will directly or indirectly (with or without notice or lapse of
time): (i) violate any provision of Commerce One's certificate of incorporation
or bylaws, (ii) constitute or result in a breach or default by Commerce One, or

the creation or imposition of any lien, claim or encumbrance on Commerce One's
assets, under any agreement or instrument to which Commerce One or any of its
subsidiaries is a party or by which Commerce One or any of its subsidiaries is
bound, which breach, default, termination, lien, claim or encumbrance would have
a Material Adverse Effect on Commerce One or would have a material adverse
effect on the ability of Commerce One to perform its obligations under this
Agreement or any of the Related Equity Agreements, or (iii) constitute a
violation by Commerce One of any Requirement of Law.

contract, obligation or commitment which is material to Commerce One or its
ability to perform its obligations under this Agreement or any of the Related
Equity Agreements.

which 192,883,704 shares were issued and outstanding, and 50,000,000 shares of
undesignated Preferred Stock, $0.0001 par value ("COMMERCE ONE PREFERRED

One Common Stock have been duly authorized, and all such issued and outstanding
shares have been validly issued, are fully paid and nonassessable and are free
of any liens or encumbrances other than any liens or encumbrances created by or
imposed upon the holders thereof. As of October 31, 2000, Commerce One has
authorized 74,552,484 shares of Commerce One Common Stock for issuance, pursuant

such outstanding stock options as of such date. In addition, 9,256,000 other

(other than those described above), warrants, rights, convertible or
exchangeable securities or other agreements outstanding as of October 31, 2000.
Except as set forth in this Section 5.4(a) or as contemplated by this Agreement,
as of October 31, 2000, there are no other options, warrants, calls, rights,
convertible or exchangeable securities, commitments or agreements of any
character to which Commerce One is a party or by which it is bound obligating
Commerce One to issue, deliver, sell, repurchase or redeem, or cause to be
issued, delivered, sold, repurchased or redeemed, any shares of the capital
stock of Commerce One or any securities convertible into or exchangeable for
capital stock of Commerce One or obligating Commerce One to grant, extend or
enter into any such option, warrant, call, right, commitment or agreement,
including but not limited to any shareholder rights plan (collectively, "EQUITY
RIGHTS"). As of the date hereof, there are no additional shares of Commerce One
Common Stock, Commerce One Preferred Stock or other shares issuable pursuant to
the Plans or Equity Rights that represent a material change to the foregoing,
and, from October 31, 2000 until the date hereof, there has not been declared,
effected or established a record date for, and neither Commerce One nor Holdco

                                   ARTICLE XI

                              ADDITIONAL AGREEMENTS

        11.1.   PREPARATION OF THE REGISTRATION STATEMENT AND THE PROXY
STATEMENT; COMMERCE ONE STOCKHOLDERS MEETING; FORMATION PROGRESS PAYMENT.

                (a)     Each of Commerce One and Holdco shall use their
reasonable best efforts to prepare and file with the SEC a proxy statement under
the Exchange Act (the "PROXY STATEMENT") and a registration statement under the
Securities Act as may be required
<PAGE>
                                                                              27

(collectively, with the Proxy Statement, the "REGISTRATION STATEMENT") in
connection with the Merger in form and substance reasonably satisfactory to
Holdco, Commerce One, Ford and GM as soon as practicable following the date of
this Agreement. Each of Commerce One and Holdco shall promptly use their
reasonable best efforts to (i) respond to any comments of the SEC, (ii) have the
Registration Statement declared effective under the Securities Act and the rules
and regulations promulgated under the Securities Act and (iii) and have the
Proxy Statement cleared by the SEC under the Exchange Act as promptly as
practicable after such filing and to keep the Registration Statement effective
as long as is necessary to consummate the Merger. Commerce One and Holdco will
notify each of Ford and GM promptly of the receipt of any comments from the SEC
and of any request by the SEC for amendments or supplements to the Registration
Statement or the Proxy Statement or for additional information and will supply
each of Ford and GM with copies of all correspondence between such party or any
of its representatives and the SEC, with respect to the Registration Statement.
Commerce One shall afford each of Ford and GM the opportunity to participate in
the SEC clearance process and any amendments or supplements to the Registration
Statement and Proxy Statement shall be in form and substance reasonably
satisfactory to Holdco, Commerce One, Ford and GM. The Registration Statement
shall comply in all material respects with all applicable requirements of law.
Whenever any event occurs which is required to be set forth in an amendment or
supplement to the Registration Statement, Commerce One and Holdco shall promptly
inform each of Ford and GM of such occurrences and shall use commercially
reasonable efforts to file with the SEC and/or mail to the stockholders of
Commerce One such amendment or supplement. Commerce One and Holdco also shall
take any reasonable action required to be taken under any applicable state
securities or "blue sky" laws in connection with the issuance of shares of

effectiveness of the Registration Statement duly call and give notice of a
meeting of its stockholders (the "COMMERCE ONE STOCKHOLDERS MEETING") for the
purpose of obtaining the Commerce One Stockholder Approval. Commerce One will
use its reasonable best efforts to cause the Proxy Statement to be mailed to
Commerce One's stockholders as promptly as practicable after the Registration
Statement is declared effective under the Securities Act. The Commerce One
Stockholders Meeting shall not be called for the purpose of voting on any
Section 11.11(a) Transaction.

                (c)     Commerce One shall, through its Board of Directors,
recommend to its stockholders that they adopt the Merger Agreement, and the
Proxy Statement shall state that each director of Commerce One intends to vote
all of the shares of Commerce One Common Stock owned by such director
individually in favor of the adoption of the Merger Agreement. Commerce One
shall and shall cause each officer of Commerce One to take such reasonable
actions as Ford or GM may request in connection with the solicitation of proxies
to vote in favor of the adoption of the Merger Agreement, including but not
limited to, (i) the engagement of a proxy solicitor, (ii) proxy solicitation by
officers of the Company in person, by letter or by telephone, (iii) a "road
show" for institutional stockholders of the Company conducted by senior
management of Commerce One (including, but not limited to, at least one of the
two officers identified in Section I of Schedule 11.1(c) or both of the two
officers identified in Section II of
<PAGE>
                                                                              28


Schedule 11.1(c)) and (iv) meetings between Commerce One's senior management
(including, but not limited to, the Chief Executive Officer of Commerce One or
the President of Commerce One) and any members of senior management of GM and
Ford to discuss additional means and strategies for encouraging Commerce One's
stockholders to adopt the Merger Agreement. Ford and GM agree to reasonably
assist Commerce One in taking any of the actions contemplated by clauses (i)
through (iv) of the previous sentence in connection with the solicitation of
proxies from Commerce One's stockholders to vote in favor of the adoption of the
Merger Agreement.

                (d)     Commerce One shall use its reasonable best efforts to
hold the Commerce One Stockholders Meeting, on a day not earlier than twenty-one
(21) days after, but not later than forty-five (45) days after, the date the
Proxy Statement is mailed.

                (e)     If on the date of the Commerce One Stockholders Meeting,
Commerce One has not received a sufficient number of proxies in favor of the
adoption of the Merger Agreement (but less than a majority of the outstanding
shares of Commerce One Common Stock have voted against the adoption of the
Merger Agreement), then Commerce One shall adjourn the Commerce One Stockholders
Meeting until the first to occur of (i) the date twenty (20) days after the
originally scheduled date of the Commerce One Stockholders Meeting or (ii) the
date on which the requisite number of proxies in favor of the adoption of the
Merger Agreement have been obtained or proxies have been received representing
more than a majority of the outstanding shares of Commerce One Common Stock
voting against the adoption of the Merger Agreement.

        11.2.    DELIVERY OF COVISINT SHARES TO HOLDCO.

                (a)     The First 1% Covisint Shares shall be released from
escrow by Covisint upon the following terms:

                (i)     if Commerce One mails the Proxy Statement to its
         stockholders pursuant to Section 11.1 within six calendar months of the
         date hereof, Covisint shall immediately release the First 1% Covisint
         Shares to Holdco (PROVIDED, HOWEVER, that (A) if the SEC staff reviews
         the Registration Statement and (B)(1) Commerce One is using reasonable
         best efforts to resolve any comments of the SEC staff relating to the
         Registration Statement or the Merger and (2) if the aggregate number of
         days elapsed between each filing of the Registration Statement, or
         amendment thereto, and the receipt of comments thereon or the
         declaration of effectiveness thereof, as the case may be (such number
         of days, the "SEC REVIEW PERIOD") exceeds 45 days, then the six
         calendar month period shall be extended by such number of days as
         equals the number of days that the SEC Review Period exceeds 45 days);

                (ii)    if the Commerce One Stockholder Approval is received
         within nine calendar months of the date hereof, Covisint shall release
         the First 1% Covisint Shares to Holdco (if such shares have not been
         previously released pursuant to clause (i) above) on the earlier to
         occur of the Merger Effective Date or the Alternative Transaction Date;
         and

                (iii)   if the Commerce One Stockholder Approval is not obtained
         within nine calendar months of the date hereof, and if the First 1%
         Covisint Shares have not been
<PAGE>
                                                                              29


         released to Holdco pursuant to Section 11.2(a)(i), then (x) Covisint
         shall immediately release half of the Ford Covisint Shares (i.e.,
         Ford's portion of the First 1% Covisint Shares) to Ford and (y)
         Covisint shall immediately release half of the GM Covisint Shares
         (i.e., GM's portion of the First 1% Covisint Shares) to GM; PROVIDED,
         HOWEVER, that if either Ford or GM has knowingly, and in bad faith,
         taken any action that delays the mailing of the Proxy Statement and
         such action is a significant cause of Commerce One's failure to mail
         the Proxy Statement to its stockholders within the time period
         specified in clause (i) above, then Covisint shall instead release the
         First 1% Covisint Shares to Holdco on the earlier to occur of the
         Merger Effective Date or the Alternative Transaction Date.

                (b)     The Second 1% Covisint Shares shall be released from
escrow by Covisint upon the following terms:

                (i)     if (A) the Commerce One Stockholder Approval is obtained
         within nine calendar months from the date hereof and (B) Covisint has
         not terminated its "Promotional Commitment" or its "Commitment to Use"
         as provided in Section 2.6.1 of the LLC Technology Agreement within the
         first 12 calendar months from the date of the LLC Technology Agreement,
         then Covisint shall immediately release the Contributed Covisint Shares
         to Holdco on the expiration of such 12 calendar month period; and

                (ii)    if the Commerce One Stockholder Approval is obtained
         within nine calendar months from the date hereof and (B) Covisint has
         terminated its "Promotional Commitment" or its "Commitment to Use" as
         provided in Section 2.6.1 of the LLC Technology Agreement within the
         first 12 calendar months from the date of the LLC Technology Agreement,
         then Covisint shall immediately release the Contributed Covisint Shares
         to Holdco on the expiration of 42 calendar months from the date of the
         LLC Technology Agreement.

                (iii)   notwithstanding any provision in this Section 11.2(b) to
         the contrary, if the Commerce One Stockholder Approval is not obtained
         within nine calendar months from the date hereof, then (x) Covisint
         shall immediately release half of the Ford Covisint Shares (i.e.,
         Ford's portion of the Second 1% Covisint Shares) to Ford and (y)
         Covisint shall immediately release half of the GM Covisint Shares
         (i.e., GM's portion of the Second 1% Covisint Shares) to GM; PROVIDED,
         HOWEVER, that if either Ford or GM has knowingly, and in bad faith,
         taken any action that materially impairs Commerce One's ability to
         obtain the Commerce One Stockholder Approval, then Covisint shall
         instead release the Second 1% Covisint Shares to Holdco on the earlier
         to occur of the Merger Effective Date or Alternative Transaction Date.

        11.3.   COSTS OF HOLDING COMPANY TRANSACTIONS. Upon consummation of the
Merger and the provision by Commerce One to Ford, GM and DC of reasonably
detailed invoices and other documentation, which invoices and documentation need
not include details of individual cost components, each of Ford, GM and DC shall
promptly reimburse Holdco for one-third of the aggregate reasonable third-party
out-of-pocket costs and expenses, up to a maximum amount of $416,666.67 for each
of Ford, GM and DC, including but not limited to legal fees, accounting fees,
SEC filing fees, Nasdaq Stock Market filing fees, and other third-party
out-of-pocket expenses relating to the Holding Company Transactions, including
SEC filings and no-action
<PAGE>
                                                                              30

letter requests, contemplated by this Agreement. In the event that the
obligations of Holdco, Commerce One and Mergerco to effect the Merger are
terminated pursuant to Section 3.1 hereof, the obligations of Ford, GM and DC to
make any payments under this Section shall be null and void.

        11.4.   TAX TREATMENT.

                (a)     In the case of the Holding Company Transactions
described in Section 2.1, (i) each of Commerce One, Holdco, Ford and GM shall
use commercially reasonable efforts to obtain an opinion of counsel to Commerce
One dated as of the Merger Effective Date substantially in the form of Exhibit D
to the effect that the Merger will qualify under the provisions of Section 351
of the Code and as a reorganization under Section 368(a) of the Code, and (ii)
each of the parties hereto shall (1) use commercially reasonable efforts to
cause such transactions to qualify under Section 351 and to cause the Merger to
qualify under Section 368(a) of the Code, (2) file all tax returns and reports
(and shall cooperate with each other in connection with such filings) in a
manner that treats such transactions as qualifying under Section 351 of the Code
(and shall file all tax returns and reports in a manner that treats the Merger
as qualifying under Section 368(a) of the Code), and (3) use its commercially
reasonable efforts to maintain the Section 351 and Section 368(a) qualification
in all proceedings involving any tax authority. If, in any audit or similar
proceeding involving any of the parties, any tax authority challenges or
otherwise questions the Section 351 and Section 368(a) qualification, such party
shall promptly inform the others, and all parties hereto shall cooperate in an
effort to maintain the Section 351 and Section 368(a) qualification.

                (b)     In the case of the Alternative Transaction described in
Section 3.1, each of the parties hereto shall (i) use commercially reasonable
efforts to cause such transaction to qualify as a reorganization under Section
368(a) of the Code, (ii) file all tax returns and reports (and shall cooperate
with each other in connection with such filings) in a manner that treats such
transaction as so qualifying, and (iii) use its commercially reasonable efforts
to maintain such qualification in all proceedings involving any tax authority.
If, in any audit or similar proceeding involving any of the parties, any tax
authority challenges or otherwise questions such qualification, such party shall
promptly inform the others, and all parties hereto shall cooperate in an effort
to maintain such qualification.

        11.5.   QUOTATION DATE. Prior to the Merger Effective Date, Holdco shall
use commercially reasonable efforts to have the Nasdaq Stock Market authorize
for quotation, at or prior to the Merger Effective Date, the shares of Holdco
Common Stock to be issued in the Merger and the GM Shares. In the event that the
Merger is not consummated, Commerce One shall use commercially reasonable
efforts to have The Nasdaq Stock Market authorize for quotation, at or prior to
the Alternative Transaction Closing Date, the Exchange Shares to be issued
pursuant to the Alternative Transaction.

        11.6.   FILINGS AND CONSENTS.

                (a)     Each party hereto will cooperate with each other party
with respect to obtaining, as promptly as practicable, and in any event prior to
the Closing, all necessary consents, approvals, authorizations and agreements
of, and the giving of all notices and making
<PAGE>
                                                                              31


of all other filings with, any third parties, including Governmental
Authorities, necessary to authorize, approve or permit the transactions
contemplated by this Agreement and the Related Equity Agreements.

                (b)     To the extent not filed prior to the date hereof and to
the extent required, as soon as practicable after the execution of this
Agreement, Holdco, Commerce One, Ford and GM each shall file with the United
States Federal Trade Commission (the "FTC") and the Antitrust Division of the
United States Department of Justice ("DOJ") Notification and Report Forms
relating to the transactions contemplated herein as required by the HSR Act, as
well as comparable notification forms required by the merger notification or
control laws and regulations of any other jurisdiction as may be necessary or
desirable to consummate the transactions contemplated hereby. Holdco, Commerce
One, Ford and GM each shall promptly (i) supply the other with any information
which may be required in order to effectuate such filings and (ii) supply any
additional information which reasonably may be required by the FTC, the DOJ or
the applicable competition or merger control authorities of any other
jurisdiction and which the parties may reasonably deem appropriate. The parties
agree to request and take such other action as shall be necessary to obtain
early termination of the HSR Act waiting period; PROVIDED that this sentence
shall apply only to the transactions contemplated by this Agreement and the
Related Equity Agreements, and PROVIDED, FURTHER, that none of Commerce One,
Holdco, Ford or GM shall be required to agree to any divestiture by such entity
or any of their respective subsidiaries or Affiliates of shares of capital stock
or of any business, assets or property of such entity or their respective
subsidiaries or Affiliates or the imposition of any material limitation on the
ability of any of them to conduct their businesses or to own or exercise control
of such assets, properties and stock.

        11.7.   COVENANT TO SATISFY CONDITIONS. Each party agrees to use all
reasonable efforts to ensure that the conditions to the other party's
obligations hereunder set forth in Article X, insofar as such matters are within
the control of such party, are satisfied as promptly as practicable.

        11.8.   FURTHER ASSURANCES. Each party shall execute and deliver such
additional instruments, documents or other writings as may be reasonably
requested by any other party in order to confirm and carry out and to effectuate
fully the intent and purposes of this Agreement. In furtherance and not in

and use commercially reasonable efforts to cause the rights and obligations of
CVX LLC under the LLC Technology Agreement to inure to Commerce One and Holdco,
as appropriate, as the direct or indirect owner of CVX LLC.

        11.9.   CONTROL AND OPERATING OF CVX LLC.

                (a)     Prior to the Merger Effective Time or the closing of the
Alternative Transaction, as applicable, without the prior written consent of
Commerce One, each of Ford, GM and Holdco shall not, and the parties hereto
shall not permit Holdco to, directly or indirectly, (i) dispose of, or cause or
permit CVX LLC to issue any equity interest in CVX LLC, (ii) cause or permit any
Person other than Commerce One, Holdco or their wholly owned subsidiaries to
beneficially own any equity interest in CVX LLC or have any right to manage or
control CVX LLC, (iii) cause or permit CVX LLC to engage in any operations or
conduct any business, except
<PAGE>
                                                                              32

for the performance of its obligations under the terms of the LLC Technology
Agreement, the Services Agreement and the Guaranty, or (iv) cause or permit
Holdco to amend its certificate of incorporation or by-laws.

                (b)     From and after the Merger Effective Time or the closing
of the Alternative Transaction, as applicable, without the prior written consent
of Ford and GM, neither Commerce One nor Holdco (nor any of their permitted
successors or assigns) shall, directly or indirectly, (i) dispose of, or permit
CVX LLC to issue, any equity interest in CVX LLC, (ii) permit any Person other
than Commerce One, Holdco or their wholly owned subsidiaries to beneficially own
any equity interest in CVX LLC or have any right to manage or control CVX LLC,

Technology Agreement, the Services Agreement and the Guaranty.

                (c)     From and after the Merger Effective Time or the closing
of the Alternative Transaction, as applicable, Holdco and Commerce One shall
cause CVX LLC to timely comply in full with each and every agreement, covenant
and obligation of CVX LLC under the LLC Technology Agreement to the same extent
as if Holdco or Commerce One, as applicable, were the obligor thereunder, it
being understood that Holdco and Commerce One's obligation hereunder is a
guaranty of performance by CVX LLC of its obligations under the LLC Technology
Agreement (subject in all cases to the terms and conditions of the LLC
Technology Agreement and all the exhibits thereto as if Holdco and Commerce One
stood in the stead of CVX LLC thereunder). This paragraph (c) shall be for the
benefit of, and enforceable by, Covisint, and is not for the benefit of, and
shall not be enforceable by, either Ford or GM.

                (d)     Prior to the Alternative Transaction Date, neither Ford
nor GM shall remove, or cause to be removed, the directors of Holdco. Ford and
GM agree to vote their shares of Holdco Common Stock in favor of the adoption of
forms of a certificate of incorporation and bylaws of Holdco requested by
Commerce One, PROVIDED that such certificate of incorporation and such bylaws
shall only become effective immediately prior to or at the Merger Effective
Time.

        11.10.  SHAREHOLDER RIGHTS PLAN. In the event that Holdco or Commerce
One adopts or has in effect a shareholder rights plan (commonly known as a
"poison pill"), each of Ford, GM, any Ford Controlled Entity and any GM
Controlled Entity shall be excepted from the operation of such plan, subject to
the terms and conditions of the Standstill Agreement and only to the extent of
the Standstill Limit, irrespective of whether the Standstill Agreement is in
effect at such time or any time in the future.

        11.11.  CERTAIN EVENTS.

                (a)     For the purposes of this Agreement, "SECTION 11.11(a)
TRANSACTION" shall mean any merger, consolidation, sale of substantially all
assets, recapitalization, reorganization, share exchange, dissolution or other
transaction by Commerce One (regardless of the manner in which effected), in
each case as a result of which shares of Commerce One Common Stock are converted
into the right, or the holders thereof are otherwise entitled, to receive stock,

date with respect to any of the following events (each, an "ADJUSTMENT
EVENT"):

                (i)     a subdivision (by stock split, stock dividend,
         recapitalization or otherwise) of shares of Commerce One Common Stock
         or the declaration of a dividend or other distribution with respect to
         Commerce One Common Stock in shares of Commerce One Common Stock;

                (ii)    a combination (by reverse stock split or otherwise) of
         the outstanding shares of Commerce One Common Stock; or

                (iii)   a reclassification, exchange, substitution,
         recapitalization, reorganization, merger, consolidation, sale of
         substantially all of its assets, share exchange, dissolution or other
         transaction (regardless of the manner in which effected), in each case
         as a result of which shares of Commerce One Common Stock are converted
         into the right, or the holders thereof are otherwise entitled, to
         receive stock, securities or other property, including cash or any
         combination thereof (other than the Merger and the Alternative
         Transaction) ("OTHER PROPERTY"),

then, in each such case, the terms of the Merger or Alternative Transaction
shall be adjusted, and the agreement, resolution or other instrument for any
such transaction shall contain provisions reasonably satisfactory to Ford and
GM, to provide that (1) each of Ford and GM shall be entitled to receive, upon
the consummation of the Merger or the Alternative Transaction, as the case may
be, that number of shares of Holdco Common Stock or Commerce One Common Stock
(or Other Property), as the case may be, that Ford or GM, as the case may be,
would have received if the Merger or Alternative Transaction had occurred
immediately prior to the occurrence of the Adjustment Event and (2) each of
Holdco and Commerce One shall take all necessary action to give effect to the
provisions of this Section (including, in the case of Holdco, a corresponding
subdivision, combination or reclassification of its shares of capital stock, as
applicable). The adjustments contemplated by this Section 11.11(b) shall be made
successively whenever any Adjustment Event shall occur. In the event of any
reclassification of shares of Commerce One Common Stock or Holdco Common Stock,
all references herein to Commerce One Common Stock or Holdco Common Stock,
respectively, shall mean and refer (except where the context otherwise requires)
to such capital stock as so reclassified.

                (c)     Until after the earliest to occur of the Merger
Effective Date or the consummation of the Alternative Transaction described in
Section 3.1 hereof, Holdco shall not (i) engage in or establish a record date
with respect to (A) any of the types of events described in Section 11.11(b),
except as shall be necessary to give effect to the provisions of Section
11.11(b), or (B) any merger, consolidation, sale of substantially all of its
assets, recapitalization or reorganization (other than the Merger), or (ii)
issue any shares of its capital stock (except in the Merger or as shall be
necessary to give effect to the provisions of Section 11.11(b)).

                (d)     Holdco and Commerce One shall at all times reserve and
keep available out of authorized but unissued shares of their Common Stock,
solely for the purpose of meeting their respective obligations under this
Agreement, a sufficient number of shares of their Common Stock to meet their
respective obligations under this Agreement. If at any time the number of
authorized but unissued shares of Common Stock of Holdco or Commerce One shall
not be sufficient to meet the obligations of Holdco or Commerce One under this
Agreement, in addition to such other remedies as shall be available to Ford or
GM, each of Holdco or Commerce One, as applicable, shall use its reasonable best
efforts to take such corporate action as may, in the opinion of its legal
counsel, be necessary to increase its authorized but unissued shares of Common
Stock to such number of shares as shall be sufficient for such purposes.

                (e)     If any event occurs of the type contemplated by the
provisions of this Section 11.11 but not expressly provided for by such
provisions, there shall be an appropriate adjustment in the number of shares of
Holdco Common Stock or Commerce One Common Stock, as the case may be, issuable
to each of Ford and GM so that following the consummation of the Merger or the
Alternative Transaction, as the case may be, each of Ford and GM shall hold the
number of shares of capital stock necessary to preserve for each of them the
economic benefits contemplated by this Agreement and the Related Equity
Agreements.

                (f)     Commerce One and Holdco shall give to each of Ford and
GM prompt written notice of any of the transactions or events described in this
Section 11.11.

        11.12.  SUCCESSION. As soon as practicable after the date hereof,
Commerce One shall seek a no-action letter from the SEC with respect to the
status of Holdco as a successor of Commerce One for purposes of the use of Form
S-3 and applicable holding periods under Rule 144 and any other similar matter.
Each of Ford and GM shall cooperate and assist Commerce One with respect to the
filing of the no-action letter request. In the event that the SEC does not issue
a no-action letter in form and substance reasonably satisfactory to Commerce One
to permit Holdco to use Form S-3 for a securities offering for which such form
would be appropriate under the applicable rules of the SEC, Ford and GM shall
each reimburse Commerce One for one-half of the additional third-party
out-of-pocket costs, including but not limited to legal fees, accounting fees,
and other third-party out-of-pocket expenses incurred by Commerce One in
preparing and filing one or more registration statements on Form S-1 during the
one year period following the Merger Effective Date, in each instance where Form
S-3 would otherwise be available for the proposed securities sale but for the
failure of the SEC to issue a favorable no-action letter relating to the right
of Holdco as successor to Commerce One to use Form S-3.

        11.13.  INDEMNIFICATION.

                (a)     GENERAL. Each of Ford and GM hereby agree to indemnify
and hold harmless Holdco and Commerce One for any and all liability, cost or
expense of Holdco or CVX LLC, including reasonable attorney's fees, arising
prior to the Closing Date and to the extent arising by reason of CVX LLC having
been a direct or indirect subsidiary of Ford and/or GM prior to the Closing
Date, other than tax matters.

                (b)     TAX MATTERS.

                                                                              35



                (i)     LIABILITY FOR TAXES.

                                (a)      Except as provided in the LLC
                Technology Agreement, Holdco and CVX LLC each shall be liable
                for and shall indemnify each of Ford and GM against all Taxes
                imposed on Holdco (but not including Taxes attributable to
                Commerce One Holding, Inc. ("COMMERCE ONE HOLDING") for any
                taxable year or period that ends on or before the Closing Date.
                In the case of any Taxes determined on a combined basis with
                Ford and GM, the amount of Taxes imposed on Holdco and CVX LLC
                or any subsidiary of Holdco shall be determined as if Holdco or
                any subsidiary of Holdco were filing tax returns on a standalone
                basis (e.g. not as part of the Ford and/or GM combined groups)
                except that (1) for income tax purposes the maximum marginal
                rate of tax on taxable income shall be used and (2) no
                alternative minimum tax shall be taken into account.

                                (b)      Ford and GM shall be liable for their
                respective share of, and shall indemnify Holdco and Commerce One
                against, all Taxes for any taxable year that ends on or before
                the Closing Date imposed on Holdco or any subsidiary of Holdco
                arising under any provision of state or foreign law similar to
                Treasury Regulation Section 1.1502-6 other than Taxes imposed by
                reason of being a member of a consolidated group of which Holdco
                is the common parent and GM shall be liable for, and indemnify
                Holdco and Commerce One against, any Taxes attributable to the
                activities or operations of Commerce One Holding.

                                (c)      For purposes of paragraphs (i)(A) and
                (i)(B) of this Section 11.13(b), whenever it is necessary to
                determine the liability for Taxes for a portion of any period
                beginning before and ending after the Closing Date (a "STRADDLE
                PERIOD"), the determination of the Taxes for the portion of the
                Straddle Period ending on and including, and the portion of the
                Straddle Period beginning after, the Closing Date shall be
                determined by assuming that the Straddle Period consisted of two
                taxable years or periods, one which ended at the close of the
                Closing Date and the other which began at the beginning of the
                day following the Closing Date, and items of income, gain,
                deduction, loss or credit for the Straddle Period shall be
                allocated between such two taxable years or periods on a
                "closing of the books basis" by assuming that the books of the
                CVX LLC, Holdco or any subsidiary of Holdco were closed at the
                close of the Closing Date; PROVIDED, HOWEVER, that exemptions,
                allowances or deductions that are calculated on an annual basis,
                such as the deduction for depreciation, shall be apportioned
                between such two taxable years or periods on a daily basis.

                (ii)    TAX RETURNS; REMITTANCE OF TAX. With respect to all Tax
         Returns that are required to be filed by or with respect to CVX LLC,
         Holdco and any subsidiary of Holdco for taxable years or periods ending
         on or before the Closing Date, Ford and GM shall (A) file or cause to
         be filed all such Tax Returns when due and (B) cause Holdco or CVX LLC
         to remit out of its funds any Taxes which are the obligation of Holdco
         or CVX LLC under this Agreement due in respect of such Tax Returns.
         Holdco (if the Merger takes place) or Commerce One (if the Alternative
         Transaction takes place) shall file or cause to
<PAGE>
                                                                              36


         be filed when due all Tax Returns of CVX LLC and Holdco not required
         to be filed by Ford and GM.

                (iii)   TAXES, ETC. For purpose of this Section, (A) "TAXES"
         means all Federal, state, local, foreign and other income, minimum,
         alternative minimum, gross receipts sales, use, ad valorem, employment,
         withholding, goods and services, value added, transfer, single-business
         or other taxes, customs duties or tariffs, fees, assessments or charges

         other tax authority or to be provided to any person under applicable
         law (including statues, regulations, rulings, or other administrative
         authorities, agreements or other applicable requirements) pertaining to
         Taxes.

                (a)     This Agreement is to be construed in accordance with and
governed by the internal laws of the State of Delaware without giving effect to

         Agreement or the subject matter hereof or thereof may not be enforced
         in or by such court; and

incurred in connection with any challenge to jurisdiction before any state or
federal court located in Wayne County, Michigan.

        12.5.   SPECIFIC ENFORCEMENT. The parties hereto agree that irreparable

breached. It is accordingly agreed that the parties shall be entitled to an
injunction or injunctions, without bond, to prevent or cure breaches of the
provisions of this Agreement and to enforce specifically the terms and
provisions hereof, this being in addition to any other remedy to which they may
be entitled by law or equity, and any party sued for breach of this Agreement

        12.9.   AMENDMENT AND WAIVER.

                (a)     This Agreement may be modified only pursuant to a
writing executed by authorized representatives of each of Ford, GM, Holdco and
Commerce One. The parties to this Agreement expressly agree that all amendments
to this Agreement must be signed by a Vice President or higher-level officer of
such party in order to be effective and enforceable against such party. The
parties expressly disclaim the right to claim the enforceability or
effectiveness of (i) any amendments to this Agreement that are not executed by a
Vice President or higher-level officer of the other parties, (ii) any oral
modifications to this Agreement, and (iii) any other amendments that are based
on course of dealing, waiver, reliance, estoppel or
<PAGE>
                                                                              40


other similar legal theory. The parties expressly disclaim the right to enforce

                (b)     No failure to exercise and no delay in exercising any
right, power or privilege granted under this Agreement shall operate as a waiver
of such right, power or privilege. No single or partial exercise of any right,
power or privilege granted under this Agreement shall preclude any other or
further exercise thereof or the exercise of any other right, power or privilege.
The rights and remedies provided in this Agreement are cumulative and are not
exclusive of any rights or remedies provided by law.

        12.10.  SUCCESSORS AND ASSIGNS. No party may assign either this
Agreement or any of its rights, interests, or obligations hereunder without the
prior written approval of the other parties; provided, however, that (a) Ford
may, without the prior written approval of Commerce One or Holdco, assign this
Agreement and each of its rights hereunder, in whole or in part, to any Person
to which Ford would then be entitled to transfer the Ford Shares under the
Standstill Agreement and (b) GM may, without the prior written approval of
Commerce One or Holdco, assign this Agreement and each of its rights hereunder,
in whole or in part, to any Person to which GM would then be entitled to
transfer the GM Shares under the Standstill Agreement; provided that in each
such case, such rights are transferred in accordance with the terms of the
Standstill Agreement and such transferee executes and delivers a counterpart or
copy of this Agreement thereby agreeing to be bound by the terms and provisions
set forth herein. Except as permitted herein, any assignment of rights or
delegation of duties under this Agreement by a party without the prior written
consent of the other parties shall be void ab initio. Subject to the preceding
two sentences, this Agreement shall be binding upon and shall inure to the
