for such Manufacturer, neither it nor any of its Affiliates shall, directly or
indirectly, acquire or Beneficially Own Voting Stock or authorize or make a

respective covenants under this Section 2.1 by virtue of any increase in the
aggregate percentage of the Total Current Voting Power of the Company

              2.2    THE MANUFACTURERS' TRANSFER RESTRICTIONS

              (a)    Each Manufacturer agrees that until the Transfer
Restriction Termination Date for such Manufacturer, it shall not, directly or
indirectly, sell, transfer, pledge, contract to sell, sell any option or
contract to purchase, purchase any option or contract to sell, grant any option,
right or warrant to purchase, transfer the economic risk of ownership of, or
otherwise dispose of (each, a "Transfer"), any Shares except:

              (i)    to the Company;

              (ii)   in the case of Ford, (A) to a Ford Controlled Entity
       so long as such Ford Controlled Entity agrees, by executing a counterpart
       to this Agreement, to (x) hold such Shares subject to all of the
       provisions of this Agreement as if it were Ford, and (y) promptly
       Transfer such Shares to Ford or to another Ford Controlled Entity if,
       prior to the Transfer Restriction Termination Date for Ford, it ceases to
       be a Ford Controlled Entity (unless it ceases to be a Ford Controlled
       Entity as a result of or after an initial public offering of its
       securities and it is not Controlled by a Company Competitor); or (B) to

       equal more than the Standstill Limit with respect to GM. Upon a Transfer
       to a Ford Controlled Entity pursuant to Section 2.2(a)(ii)(A) or pursuant

       Company Competitor, Ford shall remain a party to this Agreement and
       undertakes to the other parties hereto to procure the performance by such
       Ford Controlled Entity of its obligations pursuant to the provisions of
       this Agreement and to indemnify and hold harmless the other parties
       hereto from and against the breach by such Ford Controlled Entity of any
       of its obligations under this Agreement;

              (iii)  in the case of GM, (A) to a GM Controlled Entity so long as
       such GM Controlled Entity agrees, by executing a counterpart to this
       Agreement, to (x) hold such Shares subject to all of the provisions of
       this Agreement as if it were GM, and (y) promptly Transfer such Shares to
       GM or another GM Controlled Entity if, prior to the Transfer Restriction
       Termination Date for GM, it ceases to be a GM Controlled Entity (unless
       it ceases to be a GM Controlled Entity as a result of or after an initial
       public offering of its securities and it is not Controlled by a Company
       Competitor); or (B) to Ford or a Ford Controlled Entity, to the extent
       that such Transfer would not result in the percentage of Total Current
       Voting Power of the Company represented by all Shares

       Beneficially Owned by Ford and its Affiliates to equal more than the
       Standstill Limit with respect to Ford. Upon a Transfer to a GM Controlled
       Entity pursuant to Section 2.2(a)(ii)(B) or pursuant to Section
       2.2(a)(iii)(A), and until such time as such GM Controlled Entity ceases
       to be a GM Controlled Entity as a result of or after an initial public
       offering of its securities and is not Controlled by a Company Competitor,
       GM shall remain a party to this Agreement and undertakes to the other
       parties hereto to procure the performance by such GM Controlled Entity of
       its obligations pursuant to the provisions of this Agreement and to
       indemnify and hold harmless the other parties hereto from and against the
       breach by such GM Controlled Entity of any of its obligations under this
       Agreement;

              (iv)   in response to a bona fide public tender offer or exchange
       offer subject to Regulation 14D or Rule 13e-3 promulgated under the
       Exchange Act for cash or other consideration which is made by or on
       behalf of the Company;

              (v)    in response to a Third Party Tender Offer (A) that is not
       conditioned upon the redemption or amendment of any share purchase rights
       plan (commonly known as a "poison pill") that the Company may have in
       effect at such time, or (B) with respect to which the Board of Directors
       of the Company has approved the redemption or amendment of such "poison
       pill" to permit such Third Party Tender Offer, or (C) with respect to

       stockholders of the Company that they accept such offer pursuant to Rule
       14d-9 under the Exchange Act;

              (vi)   in the event that the Alternative Transaction (as defined
       in the Formation Agreement) occurs, each of the Manufacturers shall be

       or foreign securities exchange or automated quotation system on which the
       Company's securities are regularly traded, such Transfer must be effected
       through an investment banking firm selected by the Manufacturer from the
       following: The Goldman Sachs Group, Inc., Morgan Stanley Dean Witter &
       Co., Credit Suisse Group, Merrill Lynch & Co., Inc., and The Chase
       Manhattan Corporation or, with the prior consent of Commerce One (which
       consent shall not be unreasonably withheld or delayed), another similar
       nationally recognized investment banking firm; (y) no more than one
       million shares are sold by each Manufacturer in any single calendar week;
       and (z) if such Shares are to be sold other than on the Nasdaq or another

       which the Company's securities are regularly traded, then such Shares
       shall not be sold, directly or indirectly, to a Company Competitor;

              (vii)  in the event that a Manufacturer incurs an obligation to
       make a payment under Section 2.1(a) of the CVX Guaranty to CVX Holdco,
       such Manufacturer shall be entitled to Transfer up to that number of
       Shares, the aggregate proceeds (net of underwriting discounts, brokerage
       commissions and registration expenses, if any) of which is equal to the
       payment obligation incurred; PROVIDED, that such payment either has been
       paid prior to or is paid concurrently with the settlement of such
       Transfer or Transfers; PROVIDED, FURTHER, that (x) if such Shares are to
       be sold on the Nasdaq or

       similar nationally recognized investment banking firm; (y) no more than
       one million shares are sold by each Manufacturer in any single calendar
       week; and (z) if such Shares are to be sold other than on the Nasdaq or
       another national or foreign securities exchange or automated quotation
       system on which the Company's securities are regularly traded, then such
       Shares shall not be sold, directly or indirectly, to a Company
       Competitor; or

              (viii) as provided in subparagraphs (b) or (c) below.

              (b)    If, prior to the Transfer Restriction Termination Date with
respect to either Manufacturer, a Change in Control of the Company occurs (other
than a Change in Control involving such Manufacturer or any of its Affiliates or
a 13D Group of which such Manufacturer or any of its Affiliates is a member),
such Manufacturer shall be entitled to Transfer all or any portion of its Shares

Date for such Manufacturer, Transfer any Shares in violation of Sections
2.2(d)(i) or (ii).

              (c)    If, prior to the Transfer Restriction Termination Date, the
LLC Technology Agreement is terminated pursuant to Section 7.4.1(a) of such
agreement, each of the Manufacturers shall be entitled, beginning on the date

       plan (commonly known as a "poison pill") that the Company may have in
       effect at such time, or (B) with respect to which the Board of Directors
       of the Company has not approved the redemption or amendment of such

       Transfer, such Manufacturer has complied with the provisions of Section
       2.3 of this Agreement;

              (ii)   such Manufacturer shall not Transfer any Shares in a
       private placement that would result in the Transfer, directly or
       indirectly, of Shares to a Company Competitor unless, prior to such
       Transfer, such Manufacturer has complied with the provisions of Section
       2.3 of this Agreement; or

              (iii)  any transferee of the Shares that becomes, or is required
       to become, a party to this Agreement, shall promptly transfer such Shares
       to the Manufacturer from which it acquired the shares if such transferee
       is (or becomes) Controlled by a Company Competitor, PROVIDED that (A) a
       transferee which acquired Shares from Ford may instead transfer such
       Shares to a Ford Controlled Entity and (B) a transferee which acquired
       Shares from GM may instead transfer such shares to a GM Controlled
       Entity.

              (iv)   No transferee of any Shares that are the subject of a
       Transfer by a Manufacturer as permitted by this Section 2.2 shall be
       bound (other than a transferee that becomes, or is required to become, a
       party to this agreement after a transfer of shares in accordance with the
       provisions of this Section) by the terms of this Agreement, nor shall
       such transferee be entitled, in any manner whatsoever, to any rights
       afforded any Manufacturer under this Agreement (other than a transferee
       that becomes, or is required to become, a party to this agreement after a
       Transfer of Shares in accordance with the provisions of this Section).

              (v)    Any attempted sale, transfer or other disposition of Shares
       by a Manufacturer, a Ford Controlled Entity, a GM Controlled Entity or
       any other person that is a party to this agreement that is not in
       compliance with this Section 2.2, shall be null and void ab initio.

              (vi)   All references to Shares in this Section 2.2 shall include

              (a)    During the Standstill Period for either Manufacturer, prior
to such Manufacturer effecting any Transfer of Shares that is subject to the
first refusal rights of Sections 2.2(d)(i) or (ii), the Company shall have a
first refusal right to purchase such Shares on the following terms and
conditions:

<PAGE>
                                                                              12

              (i)    Such Manufacturer shall give prior notice (the "Transfer
       Notice") to the Company in writing of such intention, specifying the name
       of the proposed purchaser or transferee, the number of Shares proposed to
       be the subject of such Transfer, the proposed price therefor and the
       other material terms upon which such disposition is proposed to be made.

              (ii)   The Company shall have the right, exercisable by written
       notice given by the Company to such Manufacturer within ten (10) business
       days after receipt of such Transfer Notice (the "Response Notice"), to
       purchase all or any portion of the Shares specified in such Transfer
       Notice for cash at the price per share specified in the Transfer Notice
       or, if consideration other than cash is specified in the Transfer Notice,
       in an amount equal to the Fair Market Value of such non-cash
       consideration. Such right shall not be conditional upon the Company
       having sufficient financing, at the time the right arises, to purchase
       the Shares; PROVIDED, HOWEVER, in any event the Company is required to
       obtain such financing within the time period set forth in Section
       2.3(a)(iii).

              (iii)  If the Company exercises its right of first refusal
       hereunder, the closing of the purchase of the Shares with respect to
       which such right has been exercised shall take place within sixty (60)
       calendar days after the Company gives the Response Notice to such
       Manufacturer or, if later, within five (5) business days of the
       determination of the Fair Market Value of any non-cash consideration.
       Subject to Section 2.3(a)(iv), upon exercise of its right of first
       refusal, the Company and such Manufacturer shall be legally obligated to
       consummate the purchase and sale contemplated thereby and shall use their
       best efforts to secure any approvals required in connection therewith.

              (iv)   If the Company does not exercise its right of first refusal
       hereunder within the time specified for such exercise in Section
       2.3(a)(ii) above or close within the time period specified in Section
       2.3(a)(iii) with respect to all of the Shares specified in such Transfer
       Notice, such Manufacturer shall be free, during the period of ninety (90)
       calendar days following the expiration of such time for exercise or
       close, as the case may be, to Transfer or tender for Transfer those
       Shares specified in such Transfer Notice with respect to which the
       Company has not exercised its first refusal rights to the proposed
       purchaser or transferee specified in such Transfer Notice, and on terms
       not materially less favorable to such Manufacturer than the terms
       specified in such Transfer Notice.

              (b)    The Company may assign its right of first refusal under
this Section 2.3 to any other person or persons except a Ford/GM Competitor;
PROVIDED, HOWEVER, that the Company shall be liable for the timely performance
of any obligations in this Section 2.3 by such assignee.

              (b)    Until the tenth anniversary of the date of this Agreement,
(i) at any time that Ford Beneficially Owns at least 2.5% of the Total Current
Voting Power of the Company, Ford agrees not to exercise any dissenter's rights,
if any, that it may have under applicable law in connection with any merger,
consolidation or other reorganization which is approved by the Company's Board
of Directors and which is intended to qualify as a "pooling-of-interests" for
financial accounting purposes and, solely in connection with any such
pooling-of-interests transaction, Ford hereby covenants to enter into a standard
affiliate lock-up agreement if requested by the Company (PROVIDED, HOWEVER, that
all other persons required to be subject to similar limitations enter into such
agreements), regardless of the manner in which Ford may have voted or cast
Shares of Voting Stock Beneficially Owned by Ford with respect to such
transaction; and (ii) at any time that GM Beneficially Owns at least 2.5% of the
Total Current Voting Power of the Company, GM agrees not to exercise any

Company's Board of Directors and which is intended to qualify as a
"pooling-of-interests" for financial accounting purposes and, solely in
connection with any such pooling-of-interests transaction, GM hereby covenants
to enter into a standard affiliate lock-up agreement if requested by the Company
(PROVIDED, HOWEVER, that all other persons required to be subject to similar
limitations enter into such agreements), regardless of the manner in which GM
may have voted or cast Shares of Voting Stock Beneficially Owned by GM with
respect to such transaction.

              (c)    Except as set forth in paragraphs (a) and (b) above,
nothing in this Agreement shall preclude either Manufacturer from voting shares
of Voting Stock which it Beneficially Owns in such manner as such Manufacturer
determines, in its sole discretion, on any matter presented to the holders of
Voting Stock for a vote, consent or other approval.

              (d)    So long as a Manufacturer Beneficially Owns at least 2.5%
of the Total Current Voting Power of the Company, such Manufacturer, as the
holder of Shares, shall be present, in person or by proxy, at all meetings of
stockholders of the Company so that all shares of Voting Stock held by such
Manufacturer may be counted for purposes of determining the presence of a quorum
at such meetings.
