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
represented by Shares Beneficially Owned by such Manufacturer or its Affiliates

repurchase of securities by the Company or other actions taken by the Company or

Current Voting Power of the Company.

amendment to any Schedule 13D filed by such Manufacturer with respect to the
Shares.

              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
       to Section 2.2(a)(iii)(B), and until such time as such Ford Controlled
       Entity ceases to be a Ford Controlled Entity as a result of or after an

       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
       entitled to Transfer up to three million (3,000,000) Shares; PROVIDED

       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
       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;

              (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

       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 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
to any person without restriction under this Agreement, except that such

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.

Company shall promptly give notice of such requested registration to the other

(PROVIDED that if such Registration Statement is not ultimately utilized by the

Registrable Shares referred to in Section 2.1(b)(ii)(A) of the CVX Guaranty

such Registration Statement) (the "Requested Payments") and (iii) the
Manufacturers are not at the time of such request permitted under Rule 144 to
sell Registrable Shares with an aggregate fair market value at such time equal
to or greater than the Requested Payments, the Company shall as soon as
practicable file with the SEC a Registration Statement for an offering to be
made pursuant to the Shelf Rules to register under the 1933 Act resales or other
dispositions of a number of Registrable Shares with a fair market value that is

paid by the Manufacturers in connection with such registration. The fair market

cause such Registration Statement to be declared effective by the SEC as soon as
is practicable, and maintain the effectiveness of such Registration Statement

brokerage commissions and the amount of Registration Expenses to be paid by the
Manufacturers in connection with such registration) of the Registrable Shares
sold under a Registration Statement filed pursuant to Section 2.2(a)(vii) of the
Standstill Agreement be greater than the payment obligation to CVX Holdco, LLC
incurred under the CVX Guaranty. The Manufacturer or Manufacturers entitled to
sell Registrable Shares under a Registration Statement filed pursuant to Section
2.2(a)(vii) of the Standstill Agreement shall promptly pay the Company's
reasonable Registration Expenses in connection with such Registration Statement.
The Company shall not permit any holder of Registrable Securities or any other
holder of registration rights to "piggyback" on such Registration Statement
without the written consent of each of the Manufacturers. This Section 2.1(c)
shall be applicable each time a Requested Payment or Requested Payments exceed
five million dollars ($5,000,000) in the aggregate.

         2.2    DEMAND REGISTRATION.

Manufacturer (in such capacity, an "Initiating Holder") requests in writing (the
"Demand") that the Company file a registration statement on Form S-3 (or any
successor form to Form S-3) for a public offering of Registrable Shares the
Company shall promptly give written notice of such requested registration to the
other Manufacturer (in such capacity, the "Non-Initiating Holder") and thereupon
shall, as expeditiously as possible, but in any event within thirty (30) days
after its receipt of such request, subject to Section 4.1, file such
Registration Statement with the SEC to effect the registration under the 1933
Act of: (i) such Registrable Shares which the Company has been so requested to
register by the Initiating Holder; and (ii) the Registrable Shares of the
Non-Initiating Holder which the Company has been requested to register by
written request given to the Company within 15 days after the giving of such
written notice by the Company (which request shall specify the amount and
intended method of disposition of such securities). The Company shall use its
best efforts to cause such Registration Statement to be declared effective
<PAGE>
                                                                               5

as soon thereafter as practicable and keep such Registration Statement effective
until the Initiating Holder and, if applicable, the Non-Initiating Holder,
notify the Company in writing that the Company is no longer required to keep
such Registration Statement effective. In no event, however, shall the Company
be required, in any twelve-month period, to (i) effect more than two (2)
registrations pursuant to this Section 2.2 or (ii) keep one or more Registration
Statements filed pursuant to this Section 2.2 effective for more than an
aggregate of ninety (90) days. The Company shall not permit any holder of
Registrable Securities or any other holder of registration rights (other than a
Manufacturer) to "piggyback" on such Registration Statement without the written
consent of each Manufacturer participating in such registration.

         (b) Notwithstanding the foregoing, the Company shall not be obligated
to take any action pursuant to subparagraph (a):

             (i)   if the Company, within ten (10) days of the receipt of a
Demand, gives written notice to each of the Manufacturers of its bona fide
intention to effect the filing of a registration statement with the SEC relating
to a firm commitment underwriting of equity securities by the Company within
sixty (60) days of receipt of such Demand (other than with respect to a
registration statement relating to a Rule 145 transaction, the resale of
securities issued in a Rule 145 transaction, an offering solely to employees,
the registration of debt securities, or any other registration which is not
appropriate for the registration of Registrable Shares), PROVIDED, HOWEVER, that
if such registration statement is not filed by the Company within 60 days of
receipt of such Demand and declared effective by the SEC within 120 days after
the Company's receipt of the Demand, the Company shall be obligated to cause
such Registrable Shares of the Initiating Holder and, if applicable, the
Non-Initiating Holder, to be registered in accordance with the provisions of
this Section 2.2; and FURTHER PROVIDED that (x) any such registration statement
shall be subject to Section 2.3 and 2.4 hereof and (y) the Company's right under
this Section 2.2(b)(i) is subject to the Company actively employing in good
faith all reasonable efforts to cause such registration statement to become
effective; or

             (ii)  during the period starting with the Company's date of filing
of, and ending on the date ninety (90) days immediately following, the effective
date of any registration statement pertaining to equity securities by the
Company (other than a registration of securities in a Rule 145 transaction, the
resale of securities issued in a Rule 145 transaction or with respect to an
offering solely to employees, the registration of debt securities, or any other
registration which is not appropriate for the registration of Registrable
Shares), which registration was either filed as a result of the exercise by a
Manufacturer of its rights pursuant to Section 2.1 hereof or this Section 2.2 or
was subject to Section 2.3 hereof.

         2.3    PIGGYBACK REGISTRATION. If, on or after the Registration Rights
Commencement Date, the Company proposes to register (for its own account, on
behalf of its existing stockholders or a combination of the foregoing) any of
its common stock under the 1933 Act in connection with a public offering of such
common stock solely for cash (other than a registration relating primarily to
the sale of securities to participants in a Company stock plan, a Rule 145
transaction or the resale of securities issued in a Rule 145 transaction, a
registration in which the only stock being registered is common stock issuable
upon conversion or exchange of debt securities which are also being registered,
or any registration on any form which does not include substantially the same
information as would be required to be included in a Registration

                                                                               6

Statement covering the sale of the Registrable Shares), the Company shall, at
such time, give the Manufacturers notice of such registration in accordance with
Section 11.1. Upon the written request of a Manufacturer given within ten (10)
days after such notice has been given by the Company, the Company shall, subject
to Section 2.4, cause to be registered under the 1933 Act all of the Registrable
Shares that such Manufacturer has requested to be registered.

         2.4    UNDERWRITING REQUIREMENTS.

         (a) In connection with any underwritten public offering, the Company
shall not be required to include any of the Registrable Shares of a Manufacturer
in such underwriting unless such Manufacturer accepts the terms of the
underwriting as agreed upon between the Company and the underwriters for the
offering (which underwriters shall be selected by the Company).

         (b) If the total amount of securities, including Registrable Shares,
requested to be included in an underwritten public offering exceeds the amount
of securities that the underwriters determine in their sole discretion is
compatible with the success of the offering, then the Company shall be required
subject to the provisions of this Section 2.4(b) to include in the offering only
that number of such securities, including Registrable Shares, which the
underwriters determine in their sole discretion will not jeopardize the success
of the offering. In such event, the Company may reduce the number of Registrable
Shares to be included in the offering prior to reducing or excluding the shares
proposed to be offered by the Company. In the event that the number of
Registrable Shares is reduced, the Registrable Shares to be included shall be
apportioned pro rata among the Manufacturers and the holders of "Registrable
Securities" under the Existing Registration Rights Agreement according to the
aggregate number of the Registrable Shares held by the Manufacturers and the
aggregate number of shares of "Registrable Securities" held by Holders (as
defined in the Existing Registration Rights Agreement) under the Existing
Registration Rights Agreement as of the time of filing of the Registration
Statement (e.g., the piggyback rights of the holders of Registrable Shares and
the holders of Registrable Securities under the Existing Registration Rights
Agreement shall be pari passu with each other); PROVIDED, HOWEVER, that, during
the period from the Registration Rights Commencement Date until the Demand
Rights Termination Date, the aggregate number of Registrable Shares shall in no
event be reduced to an amount less than twenty-five percent (25%) of the
aggregate number of shares of common stock of the Company being offered in the
offering; PROVIDED FURTHER, HOWEVER, that from the Demand Rights Termination
Date until the first anniversary of the Demand Rights Termination Date, the
Registrable Shares to be included in the offering shall be apportioned pro rata
among all stockholders proposing to sell shares of common stock of the Company
in the offering (based on the proportionate number of shares of common stock of
the Company beneficially owned by each selling stockholder on the date the
Registration Statement relating to the offering is filed with the SEC relative
to the aggregate number of shares of common stock of the Company beneficially
owned by all selling stockholders on such date).

         3.     REGISTRATION PROCEDURES.

         3.1    BLUE SKY COMPLIANCE. The Company shall, as soon as reasonably
possible after the effectiveness of a Registration Statement, use its best
efforts to register and qualify the
<PAGE>
                                                                               7

Registrable Shares covered by the Registration Statement under such other
securities or "blue sky" laws of such jurisdictions as shall be reasonably
requested by the Manufacturers, provided that the Company shall not be required
in connection therewith or as a condition thereto to qualify to do business or
to file a general consent to service of process in any such states or
jurisdictions unless the Company is already subject to service in such
jurisdiction and except as may be required by the 1933 Act.

         3.2    FURNISHING OF PROSPECTUS. With respect to a Registration
Statement filed pursuant to Sections 2.1, 2.2 or 2.3, the Company shall furnish
to each Manufacturer selling Registrable Shares pursuant to such Registration
Statement such number of copies of a prospectus in conformity with the
requirements of the 1933 Act, and of each amendment and supplement thereto, such
number of copies of the prospectus included in such Registration Statement
(including each preliminary prospectus and summary prospectus), in conformity
with the requirements of the 1933 Act, and such other documents as such
Manufacturer may reasonably request in order to facilitate the disposition of
the Registrable Shares by such Manufacturer.

         3.3    MAINTENANCE OF EFFECTIVENESS. With respect to a Registration
Statement filed pursuant to Sections 2.1, 2.2 or 2.3, the Company shall prepare
and file with the SEC such amendments and supplements to such Registration
Statement and the prospectus used in connection therewith as may be necessary to
keep such Registration Statement effective for not less than the applicable
period specified in this Agreement.

         3.4    NOTIFICATION OF CERTAIN EVENTS. With respect to a
Registration Statement filed pursuant to Sections 2.1, 2.2 or 2.3, the
Company shall notify each seller of any such Registrable Shares covered by
such Registration Statement, at any time when a prospectus relating thereto
is required to be delivered under the 1933 Act, of the Company's becoming
aware that the prospectus included in such Registration Statement, as then in
effect, includes an untrue statement of a material fact or omits to state a
material fact required to be stated therein or necessary to make the
statements therein not misleading in the light of the circumstances then
existing, and at the request of any such seller, prepare and furnish to such
seller a reasonable number of copies of an amended or supplemental prospectus
as may be necessary so that, as thereafter delivered to the sellers of such
Registrable Shares, such prospectus shall not include an untrue statement of
a material fact or omit to state a material fact required to be stated
therein or necessary to make the statements therein not misleading in the
light of the circumstances then existing. In addition, the Company shall
notify counsel for the holders of Registrable Shares included in such
Registration Statement (i) when the Registration Statement, or any
post-effective amendment to the Registration Statement, shall have become
effective, or any supplement to the prospectus or any amendment to the
prospectus shall have been filed, (ii) of any request of the SEC after
effectiveness of the Registration Statement to amend the Registration
Statement or amend or supplement the prospectus or for additional
information, and (iii) of the issuance by the SEC of any stop order
suspending the effectiveness of the Registration Statement or of any order
preventing or suspending the use of any prospectus, or of the suspension of
the qualification of the Registration Statement for offering or sale in any
jurisdiction, or of the institution or threatening of any proceedings for any
of such purposes (collectively, a "Stop Order"). The Company shall use its
commercially reasonable best efforts to prevent the issuance of a Stop Order
specifically threatened by the SEC, and, if a Stop Order is

<PAGE>
                                                                   8

issued, use its commercially reasonable best efforts to obtain the withdrawal of
such Stop Order as soon as practicable.

         3.5    OTHER AGREEMENTS. With respect to a Registration Statement filed
pursuant to Sections 2.1, 2.2, or 2.3, if requested by a Manufacturer including
Registrable Shares therein, the Company shall use commercially reasonable best
efforts to obtain, at the expense of such Manufacturer, a "cold comfort" letter
or letters from the Company's independent public accountants in customary form
and covering matters of the type customarily covered by "cold comfort" letters.

         4.     CONDITIONS AND LIMITATIONS ON REGISTRATION RIGHTS.

         The registration rights granted by this Agreement are subject to the
following additional conditions and limitations:

         4.1    DELAYS AND SUSPENSION. The Company may delay the filing of, or
suspend or delay the effectiveness of a Registration Statement, if the Company
shall furnish to the Manufacturers a certificate signed by the Chief Executive
Officer of the Company stating that in the good faith judgment of the Board of
Directors it would be seriously detrimental to the Company or its stockholders
for such a Registration Statement to be filed or declared effective or for an
effective Registration Statement not to be suspended. In such event, the
Company's obligation under this Agreement to file a Registration Statement, seek
effectiveness of a Registration Statement or keep such Registration Statement
effective shall be deferred for a period not to exceed sixty (60) days, provided
that the Company may not exercise this right of deferral for an aggregate of in
excess of seventy-five (75) days in any one year period. If the Company suspends
the effectiveness of a Registration Statement, the Company will promptly deliver
notice to the Manufacturer or Manufacturers participating in such registration
of such suspension and will again deliver notice to such Manufacturer or
Manufacturers when such suspension is no longer necessary. The duration for
which the Company is required to keep a Registration Statement effective shall
be extended by an additional number of days equal to the length of any
suspension period.

         4.2    AMENDED OR SUPPLEMENTED PROSPECTUS. Each of the Manufacturers
agrees that, upon receipt of any notice from the Company described in Section
4.1 hereof that suspends an effective Registration Statement, such Manufacturer
shall forthwith discontinue disposition of Registrable Shares pursuant to the
Registration Statement covering such Registrable Shares until such Stockholder's
receipt of copies of a supplemented or amended prospectus from the Company, or
until it is advised in writing by the Company that the use of the prospectus may
be resumed, and has received copies of any additional or supplemental filings
which are incorporated by reference in the prospectus. If so directed by the
Company, the Manufacturers will deliver to the Company all copies of the
prospectus covering such Registrable Shares current at the time of receipt of
such notice of suspension.

         5.     INDEMNIFICATION.

        (a) The Company will indemnify the Manufacturers, each of their
respective officers, directors and partners, legal counsel, agents and each
person controlling the
<PAGE>
                                                                               9

Manufacturers within the meaning of Section 15 of the 1933 Act, with respect to
which registration, qualification or compliance has been effected pursuant to
this Agreement, and each underwriter, if any, and each person who controls any
underwriter within the meaning of Section 15 of the 1933 Act (collectively, the
"Manufacturer Indemnified Parties"), against all expenses, claims, losses,
damages and liabilities (or actions in respect thereof) to which any such
Manufacturer Indemnified Party may become subject, including any of the
foregoing incurred in settlement of any litigation, (commenced or threatened),
arising out of or based on any untrue statement (or alleged untrue statement) of
a material fact contained in any Registration Statement, prospectus, or other
document, or any amendment or supplement thereto, incident to any such
registration, qualification or compliance, or based on any omission (or alleged
omission) to state therein a material fact required to be stated therein or
necessary to make the statements therein, in the light of the circumstances
under which they were made, not misleading, or any violation by the Company of
the 1933 Act, the 1934 Act, and any state securities laws or any rule,
regulation or qualification promulgated thereunder, and the Company will
reimburse such Manufacturer Indemnified Party for any legal and any other
expenses reasonably incurred, in connection with investigating, preparing or
defending any such claim, loss, damage, liability or action; provided, however,
that the Company will not be liable in any such case to the extent that any such
claim, loss, damage, liability or expense arises out of or is based on any
untrue statement or omission or alleged untrue statement or omission in or from
any Registration Statement, made in reliance upon and in conformity with written
information furnished to the Company by any Manufacturer Indemnified Party
expressly for use therein.

         (b) The foregoing indemnity is subject to the condition that, insofar
as it relates to any such untrue statement, alleged untrue statement, omission
or alleged omission made in a preliminary prospectus on file with the SEC at the
time the Registration Statement becomes effective or the amended prospectus
filed with the SEC pursuant to Rule 424(b), as amended from time to time (the
"Final Prospectus"), such indemnity shall not inure to the benefit of (A) any
Manufacturer Indemnified Party (i) if a copy of the Final Prospectus (as amended
or supplemented, if applicable) was not furnished by a Manufacturer to the
person asserting the loss, liability, claim or damage at or prior to the time
such action as required by the 1933 Act and such Final Prospectus (as so amended
or supplemented, if applicable) would have cured the defect giving rise to the
loss, liability, claim or damage and the Company shall have previously and
timely furnished to such Manufacturer sufficient copies of the Final Prospectus
(as so amended or supplemented, if applicable), or (ii) to the extent that such
untrue statement, alleged untrue statement, omission or alleged omission is made
in reliance upon and in conformity with written information furnished to the
Company by a Manufacturer Indemnified Party expressly for use therein, or (B)
any underwriter, (i) if a copy of the Final Prospectus (as amended or
supplemented, if applicable) was not furnished to the person asserting the loss,
liability, claim or damage at or prior to the time such action as required by
the 1933 Act and the Final Prospectus (as so amended or supplemented, if
applicable) would have cured the defect giving rise to the loss, liability,
claim or damage and the Company shall have previously and timely furnished to
such underwriter sufficient copies of the Final Prospectus (as so amended or
supplemented, if applicable), or (ii) to the extent that such untrue statement,
alleged untrue statement, omission or alleged omission is made in reliance on
and in conformity with written information furnished to the Company by the
underwriter for use therein.
<PAGE>
                                                                              10

         (c) Each Manufacturer will, if Registrable Shares held by such
Manufacturer are included in the securities as to which such registration,
qualification or compliance is being effected, indemnify the Company, each of
its directors and officers, legal counsel, agents, each underwriter, if any, of
the Company's securities covered by such a Registration Statement, each person
who controls the Company or such underwriter within the meaning of Section 15 of
the 1933 Act (collectively, the "Company Indemnified Parties"), against all
expenses, claims, losses, damages and liabilities (or actions in respect
thereof) to which any such Company Indemnified Party may become subject,
including any of the foregoing incurred in settlement of any litigation
(commenced or threatened), arising out of or based on any untrue statement (or
alleged untrue statement) of a material fact contained in any such Registration
Statement, prospectus, offering circular or other document, or any amendment or
supplement thereto, incident to such registration, qualification or compliance,
or any omission (or alleged omission) to state therein a material fact required
to be stated therein or necessary to make the statements therein, in the light
of the circumstances under which they were made, not misleading, and, severally,
and not jointly, will reimburse such Company Indemnified Party for any legal and
any other expenses reasonably incurred, in connection with investigating or
defending any such claim, loss, damage, liability or action, in each case to the
extent, but only to the extent, that such untrue statement (or alleged untrue
statement) or omission (or alleged omission) is made in such Registration
Statement, prospectus, offering circular or other document in reliance upon and
in conformity with written information furnished to the Company by any
Manufacturer Indemnified Party expressly for use therein. Notwithstanding the
foregoing, the liability of such Manufacturer under this Section 5 shall be
limited to an amount equal to the net proceeds received by such Manufacturer
from the sale of shares in such registration.

         (d) Each party entitled to indemnification under this Section 5 (the
"Indemnified Party") shall give notice to the party required to provide
indemnification (the "Indemnifying Party") promptly after such Indemnified Party
has actual knowledge of any claim as to which indemnity may be sought, and shall
permit the Indemnifying Party to assume the defense of any such claim or any
litigation resulting therefrom, provided that counsel for the Indemnifying
Party, who shall conduct the defense of such claim or litigation, shall be
approved by the Indemnified Party (whose approval shall not unreasonably be
withheld), and the Indemnified Party may participate in such defense at such
party's expense, and provided further that the failure of any Indemnified Party
to give notice as provided herein shall not relieve the Indemnifying Party of
its obligations under this Agreement, unless the failure to give such notice is
materially prejudicial to an Indemnifying Party's ability to defend such action,
and provided further that an Indemnified Party shall have the right to retain
its own counsel, with the fees and expenses of such counsel to be paid by the
Indemnifying Party, if representation of such Indemnified Party by the counsel
retained by the Indemnifying Party would be inappropriate due to actual or
potential differing interests between such Indemnified Party and any other party
represented by such counsel in such proceeding. No Indemnifying Party, in the
defense of any such claim or litigation, shall, except with the consent of each
Indemnified Party, consent to entry of any judgment or enter into any settlement
which does not include as an unconditional term thereof the giving by the
claimant or plaintiff to such Indemnified Party of a release from all liability
in respect to such claim or litigation.

         (e) If the indemnification provided for in this Section 5 is held by a
court of competent jurisdiction to be unavailable to an Indemnified Party with
respect to any losses,
<PAGE>
                                                                              11

claims, damages or liabilities referred to herein, the Indemnifying Party, in
lieu of indemnifying such Indemnified Party thereunder, shall to the extent
permitted by applicable law contribute to the amount paid or payable by such
Indemnified Party as a result of such expense, claim, loss, damage or liability
in such proportion as is appropriate to reflect the relative fault of the
Indemnifying Party on the one hand and of the Indemnified Party on the other in
connection with the violation(s) that resulted in such expense, claim, loss,
damage or liability, as well as any other relevant equitable considerations. The
relative fault of the Indemnifying Party and of the Indemnified Party shall be
determined by a court of law by reference to, among other things, whether the
untrue or alleged untrue statement of a material fact or the omission to state a
material fact relates to information supplied by the Indemnifying Party or by
the Indemnified Party and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such statement or omission;
PROVIDED that in no event shall any contribution by a Manufacturer hereunder
exceed the net proceeds from the offering received by such Manufacturer.

         (f) The obligations of the Company and the Manufacturers under this
Section 5 shall survive completion of any offering of Registrable Shares in a
Registration Statement and the termination of this Agreement.

         6.     INFORMATION FROM MANUFACTURERS. It shall be a condition
precedent to the obligations of the Company to take any action pursuant to this
Agreement with respect to the Registrable Shares of a Manufacturer that such
Manufacturer shall furnish to the Company such information regarding itself, the
Registrable Shares held by it and the intended method of disposition of such
securities as shall be required to effect the registration of the Registrable
Shares.

         7.     EXPENSES OF REGISTRATION. The Company shall pay all
registration, filing and qualification fees (including SEC filing fees and the
listing fees of The Nasdaq Stock Market or any stock exchange on which the
Company securities are traded) attributable to the Registrable Shares registered
under this Agreement, and any legal, accounting or other professional fees or
expenses incurred by the Company (the "Registration Expenses"). The
Manufacturers shall pay all underwriting discounts, selling commissions and
stock transfer taxes, if any, attributable to the sale of such securities
registered by the Manufacturers and any legal, accounting or other professional
fees incurred by the Manufacturers.

         8.     REPORTS UNDER THE 1934 ACT. The Company agrees to file with the
SEC in a timely manner all reports and other documents and information required
of the Company under the 1934 Act, and take such other actions as may be
necessary to assure the availability of Form S-3 for use in connection with the
registration rights provided in this Agreement and Rule 144 for use in
connection with resales of the Registrable Shares.

         9.     RULE 144.

         (a) In the event that a Manufacturer and its Affiliates collectively
hold Registrable Shares representing less than one percent (1%) of the issued
and outstanding common stock of the Company and all of such Manufacturer's
Registrable Shares may, under Rule 144, be resold or otherwise disposed of in a
ninety (90) day period without registration
<PAGE>
                                                                              12

under the 1933 Act, the registration rights granted under Sections 2.1, 2.2 and
2.3 to such Manufacturer, and the obligations of the Company thereunder to such
Manufacturer, shall automatically terminate in their entirety and be of no
further force and effect whatsoever without any further action on the part of
the Company or such Manufacturer.

         (b) If after the Demand Rights Termination Date, all of a Manufacturer
and its Affiliates' Registrable Shares may, under Rule 144(k), be resold or
otherwise disposed of, then the registration rights granted under Sections 2.1,
2.2 and 2.3 hereof to such Manufacturer and the obligations of the Company
thereunder to such Manufacturer shall automatically terminate in their entirety
and be of no further force and effect whatsoever without any further action on
the part of the Company or such Manufacturer; PROVIDED, HOWEVER, that the
Piggyback Registration Rights granted pursuant to Section 2.3 shall survive
until the first anniversary of the Demand Rights Termination Date.

         10.    MARKET STAND-OFF. Each of the Manufacturers agrees that, at any
time that it owns Shares (as defined in the Standstill Agreement) that represent
two and one-half percent (2.5%) or more of the Total Current Voting Power (as
defined in the Standstill Agreement) of the Company, upon the request of the
underwriters managing any underwritten public offering of the Company's
securities in connection with an effective Registration Statement under the 1933
Act, not to offer, pledge, sell, 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, or otherwise transfer or dispose of, directly or
indirectly, the Registrable Shares held by such Manufacturer, other than those
included in the registration, without the prior written consent of such
underwriters, for such period of time, not to exceed ninety (90) days (or such
lesser period as officers or directors of the Company are so restricted with
respect to the transfer of shares of common stock of the Company held by them)
after the effective date of the Registration Statement relating thereto;
PROVIDED that (x) such registration was filed as a result of the exercise by
such Manufacturer of its rights pursuant to Section 2.1 or 2.2 hereof or such
Manufacturer participated in or had the right to participate in such
Registration Statement pursuant to Section 2.3 hereof and (y) such
Manufacturer's registration rights under this Agreement shall not have been
terminated pursuant to Section 9. Each of the Manufacturers agrees that the
Company may instruct its transfer agent to place stop-transfer notations in its
records to enforce the provisions of this Section 10.

         11.    MISCELLANEOUS.

         11.1   NOTICES. All notices and other communications required or

other purposes of such void or unenforceable provision.

         11.7   CERTAIN COMPANY REPRESENTATIONS. This Agreement has been duly
authorized by all necessary action by the Board of Directors of the Company and
the stockholders of the Company, and the Company's execution, delivery and
performance of this Agreement does not violate any other agreement or instrument
to which it is currently a party. As of the date hereof, the Company has not
