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

          (a)  Affirmative Covenants.
               ---------------------

               1.   Quantum shall use all commercially reasonable efforts to

shall receive all the benefits of an existing stockholder under any
anti-takeover plan or program which Quantum may adopt, be it through amendment
of its Certificate of Incorporation and/or its Bylaws to include additional
provisions deemed to have an anti-takeover effect, or otherwise.

               4.   Quantum shall acquire from its parent company, IMPCO,

the Quantum-Owned Technology or Jointly-Owned Technology (as defined in the
Development Agreement) except in the ordinary course of business as may be
required by commercial lenders; provided, however, that no such

                                      -4-
<PAGE>

encumbrances shall have the effect of limiting or restricting in any fashion the

Jointly-Owned Technology as provided in this, and in the Development Agreement,
without the prior written approval of GM having been obtained.

               2.   Quantum shall not grant any exclusive license to the

provided, however, that such prohibition shall not be applicable to the issuance
or sale of shares of Common Stock (or options therefor) to employees, directors
and consultants for the primary purpose of soliciting or retaining their

                                   ARTICLE III
                                   -----------

                         BUSINESS DEVELOPMENT ACTIVITIES
                         -------------------------------

     3.1  Joint Efforts. The Parties shall work together to develop and share
          -------------
sourcing and marketing strategy in connection with the enhancement and
commercialization of the Business.

     3.2  Joint Research and Development. GM and Quantum shall use their best
          ------------------------------
efforts to jointly develop Statements of Work for product research and
development as further set forth in the Development Agreement.

     3.3  Commercial Team. Within ten (10) business days of the Effective Date,
          ---------------
each Party shall assign one (1) member ("Member") to a joint commercial steering
team to meet and cooperate to define and manage the efforts associated with this
Agreement ("Commercial Team"). The Members shall include business development
representatives with sufficient authority and experience to make recommendations
with respect to the usefulness, marketability, and all inter-related business
development opportunities relating to the Projects defined in the Development
Agreement or any other aspect of the Business which the Members deem
appropriate. Either Party may replace its Member in its sole discretion upon
notice to the other Party. Each Party shall bear its own costs and expenses
related to the Commercial Team. At least the first meeting of the Commercial
Team shall be face-to-face.

          (a)  The Commercial Team shall, among other things, consider and
determine, where appropriate, the marketability of specific Projects (as

                                      -5-
<PAGE>

defined in the Development Agreement). Prior to any commercial release thereof,
the Members shall determine a marketing plan addressing distribution rights for
the given Project, customer support obligations, joint business development
efforts, identification of strategic marketing opportunities and distribution
channels, promotions and press releases, packaging, and product endorsement
opportunities.

          (b)  At the first meeting of the Commercial Team, to be held at a time
and location as mutually agreed, the Members shall discuss the current state of
the Market and the Business, and perform an initial assessment as to the
associated market conditions ("Commercial Roadmap"). From time to time, the
Commercial Team may modify the Commercial Roadmap as deemed necessary.

          (c)  If the Commercial Team Members cannot reach a decision on a
particular issue, including modifications to the Commercial Roadmap, senior
managers of Quantum and GM will meet and negotiate in good faith to resolve the
issue within a reasonable period of time. If the issue is not resolved within
thirty calendar (30) days, the Commercial Roadmap will remain unchanged.
Notwithstanding the foregoing, neither Party shall be required to implement a
decision of the Commercial Team if such decision may reasonably result in legal
liability for such Party.

     3.4  Trademarks. No rights to use GM or Quantum trademarks or trade dress
          ----------
are granted under this Agreement. Any such rights shall only be granted pursuant
to the terms of a written license agreement executed by each of the Parties.

     3.5  Joint Communication Strategy. The Parties hereto shall consult and
          ----------------------------
cooperate with each other as to the form and substance of any press release or
other public disclosure related to this Agreement, the transactions contemplated
hereby or the subject matter hereof. Quantum agrees to submit to GM for its
prior review and approval any press release or similar document or disposition
designed for public consumption which mentions GM. Notwithstanding the
foregoing, nothing in this Section 3.5 shall be deemed to prohibit Quantum or GM
from making any disclosure necessary in order to satisfy such Party's disclosure
obligations imposed by law.

     3.6  Sourcing and Production. The Parties agree that there are no
          -----------------------
pre-commitments on sourcing or production from either Party. GM purchases from
Quantum of advanced gaseous storage and handling systems or other related
automotive components will be concluded on the then standard GM Purchase Order
terms and conditions, and all such purchases will be contingent upon Quantum
maintaining competitiveness with regard to Quality, Service, Technology and
Price ("QSTP"). In the event Quantum fails to compete

                                      -6-
<PAGE>

successfully with other products or services performing the same, similar or
substitute functionality, GM is free to purchase the competitive product and to
refrain from making purchases from Quantum. Where Quantum is supplying
components for GM production vehicles, standard automotive industry access
rights as detailed in the GM Purchase Order will apply.

     3.7  Distribution.
          ------------

          (a)  Distribution by GM. GM shall have the right to distribute
               ------------------
products and technology in accordance with the rights provided in the
Development Agreement, subject to the following restrictions: (i) all such
products shall be distributed under agreements that shall not adversely affect
Quantum's rights and protections agreed upon in the Development Agreement and
this Agreement; and (ii) to distribute any Quantum software included in such
products in object code form only as an integral part of the relevant system.

          (b)  Distribution by Quantum. Quantum shall have the right to
               -----------------------
distribute products and technology in accordance with the rights provided in the
Development Agreement, subject to the following restrictions: (i) all such
products shall be distributed under agreements that shall not adversely affect
GM's rights and protections agreed upon in the Development Agreement and this
Agreement; and (ii) to distribute any GM software included in such products in
object code form only as an integral part of the relevant system.

          (c)  Customers. GM shall provide software and hardware support to its
               ---------
customers, including products purchased from GM's distributors; and Quantum
shall provide software and hardware support to its customers, including products
purchased from Quantum's distributors.

          (d)  Agreements with Distributors and Original Equipment Manufacturers
               -----------------------------------------------------------------
("OEM"). Each Party shall negotiate the terms and conditions of its own
-------
distribution agreements and OEM agreements. Each Party agrees, however, that
such agreements will be written agreements, and will include all of the
provisions contained herein which relate to confidentiality, production, and
distribution.

          (e)  Packaging. Each Party is free to package the products as it so
               ---------
chooses, so long as it does not choose packaging that contains "Objectionable
Material." Objectionable Material, for purposes of this Agreement, means any
content or representation that is obscene, offensive, defamatory, libelous,
dangerous, derogatory or discriminatory toward any individual, group or
organization, or an infringement of the intellectual property rights of any
Party or any third party.

     4.3  Final Revenue Sharing Payment. At year [****], Quantum will pay to
          -----------------------------
GM the present value of future revenue sharing payments that would otherwise be
payable to GM on an annual basis. Such future payments assume an income stream
to GM of [****]% of Quantum Fuel Cell System-related gross revenues in
perpetuity. Valuation methodology and assumptions (which must be reasonable,
theoretically sound, and consistent with industry practice), will be determined
in the year [****] by GM and Quantum. In the event the Parties do not agree on a
fair present value, the Parties will jointly select and pay for an independent
valuation from a third party whose valuation will be binding.

     4.4  Payment Detail. For revenue sharing payments that Quantum is obligated
          --------------
to make to GM, such payments shall be payable annually within forty-five (45)
calendar days following the end of the fiscal year in which the gross revenues
serving as the basis therefor were received. Quantum shall provide a report with

during the fiscal year for which payments are owed, and (b) a description of the
products sold; and (c) a calculation of the payment due.

     4.5  Books, Records, and Audit. Quantum shall keep complete and accurate
          -------------------------
records which support the payments called for in this Article IV. These records
shall be retained for a period of at least three (3) years from the date of the
applicable payment or report, notwithstanding the expiration or other
termination of this Agreement, the Development Agreement or of any Statement of
Work. GM or its designated accounting firm shall have the right to examine and
audit, not more than once a year unless the preceding audit revealed a
discrepancy, and during normal business hours, all such records and such other
records and accounts as may contain, under recognized accounting practices,
information bearing upon the amount of payments due to GM hereunder.

     4.6  Taxes. All payments required by this Article IV are exclusive of any
          -----
and all federal, state, local and foreign taxes, duties, excises, fees, levies
and assessments that may be imposed by any taxing authority on the payments or
the gross revenues on which they are based. Each Party agrees to bear and be
responsible for, and to pay directly to the appropriate taxing authority, all
such taxes, duties, excises, fees, levies and assessments for which such Party
is legally responsible.

shall have met its obligations under the Development Agreement, the Stock
Transfer Agreement and this Agreement, Quantum shall then have the continuing
obligation to make revenue sharing payments pursuant to Article IV hereof
following termination of this Agreement.

parties, then Quantum shall offer to GM the right to purchase such Quantum-Owned
Technology or Jointly-Owned Technology (hereinafter the "Offered Technology") on
the same terms (or terms as similar as reasonably possible) and conditions as
set forth in a written notice of the proposed Transfer (hereinafter the
"Transfer Notice"). The Transfer Notice shall include (i) a description of the
Offered Technology, (ii) the identity of the prospective transferee(s), (iii)
the consideration and the material terms and conditions upon which the proposed
Transfer is to be made, and (iv) the expected closing date for the Transfer. The
Transfer Notice shall also include a copy of any written proposal, term sheet or
letter of intent or other agreement relating to the proposed Transfer, and
Quantum shall certify that it has a good faith belief that a binding agreement
for the Transfer is obtainable on the terms described in, or attached to, the
Transfer Notice. Upon written notice by GM within twenty (20) business days of
its receipt of the Transfer Notice, GM may notify Quantum in writing of its
desire to purchase the Offered Technology from Quantum at the same price, and
upon the same terms (or terms as similar as reasonably possible) as described in
the Transfer Notice, and Quantum shall transfer the Offered Technology to GM
pursuant to such terms.

     6.2  Transfer Period. If the Offered Technology is not purchased by GM
          ---------------
pursuant to Section 6.1, Quantum shall be entitled for a period of sixty (60)
calendar days thereafter to complete the proposed Transfer of the Offered
Technology upon the terms and conditions specified in the Transfer Notice. If
Quantum has not so transferred the Offered Technology during such period,
Quantum shall not thereafter make a Transfer of the Offered Technology without
again first offering such assets to GM in the manner provided in Section 6.1.

     6.3  Valuation of Property. Should the purchase price specified in the
          ---------------------
Transfer Notice be payable in property other than cash or evidences of
indebtedness, GM shall have the right to pay the purchase price in the form of
cash equal in amount to the value of such property. If Quantum and GM cannot
agree on such cash value within twenty (20) business days after GM's receipt of
the

<PAGE>

Transfer Notice and by the time GM notifies Quantum of its intent to
purchase the Offered Technology pursuant to Section 6.1 above, the valuation
shall be determined by an independent appraisal firm selected and approved by
Quantum and GM, which approval shall not be unreasonably withheld. The cost of
such appraisal shall be borne by GM. The appraisal shall be completed and the GM
purchase closed within thirty (30) business days thereafter. If the time for the
closing of GM's purchase has expired because the determination of the value of
the purchase price offered by the prospective transferee(s) has not been timely
received, then such closing shall be continued and held on or before the fifth
(5th) business day after such valuation shall have been made pursuant to this
Section 6.3.

                               RIGHT TO PURCHASE
                               -----------------

     7.1  Right to Purchase. In the event of any decision by Quantum to
          -----------------
discontinue the Business or otherwise upon any liquidation, dissolution or
winding up of Quantum, whether voluntary or involuntary, under the dissolution
provisions of the Delaware General Corporation Law ("DGCL") ss. 275 et seq., or
any successor statute, Quantum shall give notice to GM of such decision, and GM
shall have the right to purchase the Quantum-Owned Technology and/or the
Jointly-Owned Technology on the terms and conditions approved by the Board in
accordance with the provisions of Section 7.2 below.

     7.2  Determination of Fair Market Value of the IP. The Parties hereby agree
          --------------------------------------------
that the fair market value of such Quantum-Owned Technology and Jointly-Owned
Technology (hereinafter the "Technology FMV") shall be determined by an
independent appraisal firm with proven expertise in the field of valuation of
intellectual property chosen and paid for by GM and approved by the Board, which
approval shall not be unreasonably withheld. Such valuation shall be binding
upon the Parties with regard to the exercise of GM's right to purchase under
this Article VII.

     7.3  Exercise of Right. In order properly to exercise its right to purchase
          -----------------
hereunder, GM shall have ten (10) business days after determination of the
Technology FMV to decide whether to purchase such Quantum-Owned Technology
and/or Jointly-Owned Technology and, if it decides to do so, the transaction
shall close within an additional twenty (20) business days subject to the
requirement for any regulatory, judicial or other third party approvals.

          (a)  In the case of a proposed dissolution, if GM does not purchase
the Quantum-Owned Technology and/or Jointly-Owned Technology as provided herein,
Quantum shall be entitled to discontinue the Business or to

                                      -12-
<PAGE>

pursue dissolution proceedings to the extent it has the right to do so under the
DGCL.

          (b)  Notwithstanding the foregoing, if the proposed dissolution has
not commenced within ninety (90) calendar days of GM's refusal to purchase the
Quantum-Owned Technology and/or Jointly-Owned Technology, GM's rights under this
Article VIII shall be revived.

     7.4  Right to Purchase in Event of Insolvency. In the event Quantum is
          ----------------------------------------
deemed by a court of competent jurisdiction to be insolvent, either (a) because
the sum of its debts is greater than all of its property at fair valuation; (b)
because it is unable to pay its debts as they become due; and/or (c) because it
is the subject of a voluntary or involuntary petition under the United States
Bankruptcy Code (11 U.S.C. Sections 101 et seq.) which is not dismissed within
sixty (60) calendar days, or the subject of an assignment for benefit of
creditors, receivership, service of a writ of attachment or replevin with
respect to a material part of its property, or the subject of an appointment of
a custodian, keeper, conservator or trustee over Quantum or part or all of its
assets, or the subject of a regulatory seizure, conservatorship or receivership
or foreclosure of a material part of its property, then GM shall be given the
opportunity to purchase the Quantum-Owned Technology and Jointly-Owned
Technology subject to all necessary or appropriate regulatory and judicial
approvals, at the value as determined in accordance with the applicable and
appropriate regulatory and/or judicial procedures.

prescribed by the AAA, provided that at least one (1) copy of the Arbitration
Demand must be sent to the other Party hereto. Within fifteen (15) business days
of delivery of the Arbitration Demand, each Party shall appoint one (1)
arbitrator. If a Party does not select an arbitrator, the selected arbitrator
shall serve as the sole arbitrator. If both Parties select arbitrators, the
selected arbitrators shall, within fifteen (15) business days of their
appointment, appoint an additional arbitrator. In the event that the arbitrators
selected by the Parties are unable to agree upon the selection of the additional

Once selected, the arbitration panel shall meet as expeditiously as possible,
select a chairman, schedule the arbitration hearing, and notify the Parties in
writing of the date, time and place of the hearing.

made in accordance with the internal laws of the state of Delaware without
regard for its conflict of laws doctrine. Any award rendered by the arbitrators
shall be accompanied by a written opinion setting forth the findings of fact and
conclusions of law relied upon in reaching their decision. The award rendered by
the arbitrators shall be final, binding and non-appealable, and judgment upon
such award may be entered by any court having jurisdiction thereof. The Parties
agree that the existence, conduct and content of any such arbitration shall be
kept confidential and that no Party shall disclose to any third party any
information about such arbitration, except as may be required by law or for
financial reporting purposes in each Party's financial statements.

by Delaware law, excluding its conflict of laws rules. With the

                                      -17-
<PAGE>

exception of either Party's right to enforce its proprietary rights through
injunctive relief, and consistent with the Parties' obligations to submit
disputes to arbitration pursuant to the terms of Article VIII hereof, all
disputes arising out of this Agreement shall be subject to the exclusive
jurisdiction and venue of the California state and federal courts located in
Orange County, California, and the Parties consent to the personal and exclusive

application of the United Nations Convention on the International Sale of Goods

     11.4 Waiver. The delay or failure of a Party to exercise any right, power,
remedy, or privilege hereunder or failure to strictly enforce any breach,
violation, default, provision or condition shall not impair any such right,
power, remedy or privilege nor shall it constitute a waiver thereof or
acquiescence thereto. Any waiver, permit, consent, or approval of any kind
regarding any breach, violation, default, provision or condition of this
Agreement must be in writing and shall be effective only to the extent
specifically set forth in such writing. No partial waiver of any such right,

without the prior written approval of the other Party except to the successor in

illegal, or unenforceable by any tribunal, then such provision shall be deemed
automatically adjusted to conform to the requirements for validity as declared
at such time and, as so adjusted, shall be deemed a provision of this Agreement
as though originally included herein. In the event that the provision deemed
invalid, illegal or unenforceable is of such a nature that it cannot be so
adjusted, the provision shall be deemed deleted from this Agreement as though
the provision had never been included herein. If any provision or portion of
this Agreement is

                                      -18-
<PAGE>

held to be unenforceable or invalid, the Parties agree to negotiate, in good

FOREGOING, IT IS EXPRESSLY UNDERSTOOD AND AGREED THAT EACH AND EVERY PROVISION
OF THIS AGREEMENT WHICH PROVIDES FOR A LIMITATION OF LIABILITY, DISCLAIMER OF

granted any right or authority to assume or create any obligation or
responsibility, express or implied, on behalf of or in the name of the other
Party, or bind the other Party in any matter or thing whatsoever, including but
not limited to, the right or authority to obligate the other Party to accept or
deliver any order, or to sell or refuse to sell to any potential customer.

     11.9  Remedies Cumulative. All remedies, either under this Agreement or by
law or otherwise afforded to any Party, shall be cumulative and not exclusive or
alternative and shall be in addition to all remedies given hereunder or now or
thereafter existing, at law or in equity, by statute or otherwise. The election
of any one or more remedies by any Party shall not constitute a waiver of the
right to pursue other available remedies.

     11.10 Injunctive Relief. The Parties acknowledge that any breach of the
provisions of this Agreement relating to proprietary rights of either Party may
cause irreparable harm and significant injury to an extent that may be difficult
to ascertain. Accordingly, each Party agrees that the other Party will have, in
addition to any other rights or remedies available to it at law or in equity,
the right to seek injunctive relief to enjoin any breach or violation of such
sections.

     11.11 Force Majeure. Either Party shall be excused from any delay or

obligations and rights of the Party so excused shall be extended on a day-to-day
basis for the period of time equal to that of the underlying cause of the delay;
provided that such Party shall give notice of such force majeure event to the
other Party as soon as reasonably possible.

     11.12 Counterparts. This Agreement may be executed in one or more
counterparts, each of which shall constitute an original, but taken together
shall constitute one and the same document.
