consult with AMG regarding such requests and in good faith fully consider AMG's
positions, suggestions and strategies.

    7.9   Governmental Authority Finding. In the event of a finding by any
          ------------------------------
governmental agency of any safety defect or noncompliance with any governmental
safety standard or regulation or governmental emissions control or fuel economy
standard or regulation or other applicable law relating to the New Vehicles, (a)
negotiations with that governmental agency about the amount of civil penalties,
fines or other monetary assessment, or a recall or notification campaign, and
(b) a decision on whether to challenge the findings of such, will be conducted
or made solely by GM.

    7.10  GM Consultation with AMG. GM shall keep AMG fully informed of any
          ------------------------
representation before any governmental agency and any proceedings in that
connection as well as any findings by any governmental agency and any
negotiations and decisions by GM. If GM determines it is necessary to conduct a
recall campaign involving the New Vehicle, GM and AMG will consult in good

                                      -9-
<PAGE>

faith to determine the nature of any corrective action to be taken concerning
the New Vehicle, and GM will issue whatever notification letters are required
and conduct the recall campaign.

    7.11  Voluntary Recall Campaigns. If, as the result of field experience,
          --------------------------
test data or otherwise, either GM or AMG finds that there may be a safety or
emissions related defect or noncompliance involving the New Vehicle, even though
not involving an inquiry from or determination of any governmental agency, it
will immediately notify the other party, whereupon GM, after consultation with
AMG, will have the right to issue notification letters or conduct a voluntary
recall campaign in connection therewith.

    7.12  Reports to Governmental Authorities.  GM will submit to the
          -----------------------------------
applicable governmental agency all reports and data applicable to the New
Vehicles and required to be submitted under any applicable law.  Any information
reasonably necessary for such reports will be furnished to GM by AMG, and AMG
will give reasonable assistance to GM in the preparation of such reports.  GM
will prepare all notices, bulletins and other communications to GM Authorized
Dealers regarding any defects in the New Vehicles.  GM will endeavor to keep AMG
informed of, all information and reports and data filed with any governmental
agency with respect to the New Vehicles and provide AMG with copies of all such
materials upon AMG's request.

                                   SECTION 8
                                   ---------

                           Product Liability Claims
                           ------------------------

    8.1   Indemnities.   GM and AMG shall each indemnify, defend and hold
          -----------
harmless the other from and against any liabilities, claims, and demands arising
out of the death of or injury to any person or damage to any property alleged to
have resulted from a defect in or malfunction of any of the New Vehicles,
consistent with the provisions of this Section 8.

    8.2   Communication and Cooperation.   With respect to any actual,
          -----------------------------
potential or threatened product liability claim, action or proceeding relating
to any New Vehicle, GM and AMG shall (i) communicate and cooperate with each
other and, if required, with the appropriate insurance carrier, to the fullest
extent reasonably possible in investigating the facts and circumstances
surrounding the claim and in litigating the matter; (ii) refrain to the fullest
extent reasonably possible from taking positions adverse to the interests of
each other, and (iii) not, except in enforcement of any rights under this
Agreement, institute any claim, action or proceeding, whether by cross-claim,
third-party claim, interpleader or otherwise, against each other.

    8.3   Product Liability Insurance.   Recognizing that it would be
          ---------------------------
undesirable to rely upon third party practice or other legal actions to enforce
each party's rights against the other under this Section 8, AMG has become and
will continue to be, for as long as this Agreement is in effect, an additional
insured under a GM Product Liability Program. GM shall be reimbursed for the
costs associated with such insurance through a payment by AMG in the amount of
$150.00 per New Vehicle assembled by AMG; provided, however, that GM shall be
                                          -----------------
fully responsible for any deductibles and/or self insured portion of such
insurance. Upon AMG's written request, GM will furnish AMG with certificates of
insurance verifying the relevant insurance coverages and identifying AMG as an
additional insured.

    8.4   Non-Disclosure.  GM and AMG agree not to disclose to any third
          --------------
parties any information with respect to the arrangements set forth under this
Section, unless required as a matter of law, in any judicial proceedings, or SEC
or similar mandatory filings, without the prior written consent of the other
party which shall not be unreasonably withheld.

    8.5   Management of Product Liability Lawsuits and Claims. Because AMG will
          ---------------------------------------------------
be an additional insured under the GM Product Liability Program, GM as between
the parties shall have the right and responsibility to manage all lawsuits and
all product liability claims relating to New Vehicles covered under this
Agreement. GM shall have the right to select counsel to defend GM and AMG in
product liability lawsuits and claims; provided, however, that GM shall consider
in good faith any objections that AMG may have with regard to such counsel,
including potential conflicts of interest between such counsel and AMG. GM shall
have the right and responsibility to make all case decisions, including whether
and when to settle and how much money to pay. The parties agree to work together
to establish and develop appropriate procedures and practices to make sure that
AMG is kept adequately informed on a current and timely basis regarding the
status of any claims and lawsuits. In the event a product liability claim or
lawsuit is brought against AMG relating to any New Vehicle, AMG shall as
promptly as practicable in the circumstances forward to GM Legal Staff every
summons and complaint and every other court document received by AMG and in no
event shall AMG take any action for defense or settlement without the consent of
the GM Legal Staff.

    8.6   Costs and Expenses for Investigation and Discovery.  The above
          ---------------------------------------------------
provisions notwithstanding, GM and AMG will bear their respective costs and
expenses incurred in connection with

                                      -11-
<PAGE>

cooperating during any investigation of claims and lawsuits, including those
costs incurred for (i) searching for and producing any documents that may be
called for during any discovery proceedings; (ii) answering any interrogatories
or other discovery requests, including any interpreter costs, (iii) identifying
any potential deponents or trial witnesses, (iv) producing any of their
respective employees, retirees, consultants, or experts, for any deposition or
trial testimony; and (v) producing any sample or component parts that may be
necessary for analysis of any technical issues for any claim or lawsuit defense
of any Vehicles covered under the terms of this Agreement.

    8.7   Uninsured or Uninsurable Excess Payments.  With respect to any
          ----------------------------------------
payments that may be necessary to satisfy any judgments that not covered by such
insurance, the parties agree that responsibility for those payments shall be
apportioned 100% to GM.


                                   SECTION 9

                             Term and Termination

    9.1   Term. Unless sooner terminated or extended in accordance with the
          -----
provisions hereof, this Agreement shall commence on the Effective Date and shall
remain in effect through December 31, 2009.  GM may, in its sole discretion,
extend this Agreement for one or more years from the scheduled date of
expiration by giving notice thereof to AMG not less than one year prior to the
then-scheduled expiration.  Promptly following receipt of such notice, AMG and
GM shall negotiate in timely manner and in good faith any required adjustments
(up or down) to the Assembly Fee to be received by AMG during the extension
period.

    9.2   Term Adjustment. The above provision regarding the specific term of
          ---------------
this Agreement notwithstanding, the parties mutually acknowledge the potential
for the timing of vehicle programs to be accelerated or delayed for a variety of
reasons. The parties further acknowledge that it is their mutual intent for this
Agreement to cover a expected production run of approximately 7 1/2 to 8 years
beginning on a date to be mutually agreed upon by the parties. In this regard,
the parties agree that, in the event the timing of the New Vehicle Launch is
either accelerated or delayed, as the case may be, the term of this Agreement
will be adjusted as necessary to achieve a 7 1/2 to 8 year production run.
Additionally, in the event that GM fails to order a minimum of 5,000 New
Vehicles (including derivatives thereof) during any calendar year, the parties
shall promptly meet to identify and discuss the cause or causes for such low
volume of orders and jointly develop and implement a mutually acceptable plan
for going forward with the project contemplated herein, including the possible
adjustment (up or down) of the term of this Agreement and/or an appropriate
modification of the Assembly Fee specified in Exhibit D.

    9.3   Termination of this Agreement. Either party may immediately cancel
          -----------------------------
this Agreement in any of the following events: (a) the other party materially
breaches this Agreement and fails to cure such breach within a commercially
reasonable period of time under the circumstances following written notice; (b)
the other party enters bankruptcy, receivership, liquidation, composition of
creditors, dissolution or similar proceeding; or (c) a significant portion of
the assets of the other party necessary for the performance of this Agreement
becomes subject to attachment (unless cured within a commercially reasonable
period of time), embargo or expropriation.

    9.4   Special Termination Rights.  GM may terminate this Agreement in
          ---------------------------
the event twenty percent (20%) or more of AMG becomes owned or controlled,
directly or indirectly, by a competitor of GM in the business of manufacturing
motor vehicles.

          -----------------
of any of the events set forth in the preceding subsection 9.3 and AMG shall
advise GM immediately of the occurrence of any of the events set forth in the
preceding subsections 9.3 and 9.4.

    9.7   Pre-Existing Orders. Any bone fide customer order which may have been
          -------------------
taken by GM prior to any notice of termination hereunder shall not be affected
by such termination, and upon GM's request, AMG shall utilize its reasonable
best efforts to assist GM in the fulfillment of such order, including but not
limited to the assembly of the New Vehicle contemplated therein.

    9.8   Sums Owing. Termination of this Agreement shall not release either
          ----------
party from payment of any sum which may be due and owing to the other party
under the terms of this Agreement.

    9.9   Rights Following Termination or Expiration.  Termination or
          ------------------------------------------
expiration of this Agreement will not affect any liability which (a) has arisen
prior to such termination or expiration; or (b) may arise after such termination
or expiration based on transactions made prior to such termination or
expiration, or any obligations which, from the context hereof, are intended to
survive termination or expiration of this Agreement.

    9.10  Other Rights and Remedies. Upon the breach by either party hereto of
          -------------------------
any covenant or warranty hereunder, the party damaged by any such default or
breach may, in its sole discretion, in addition to exercising any other remedies
provided for hereunder, proceed in to protect and enforce its rights, to recover
any damages to which it may be entitled (including all costs and expenses
reasonably incurred in the exercise of its remedy), or to seek specific
performance by the other party of such other party's obligations under this
Agreement; provided, however, in no case shall either party be liable to
           -----------------
the other for indirect, special or consequential damages (subject to Section 4.3
of the Master Agreement).
