         terms and conditions of this Agreement, Quantum hereby grants to IMPCO
         effective as of the Contribution Date, and IMPCO hereby reserves the
         non-exclusive, assignable, sublicenseable, royalty-free, paid-up,
         irrevocable right and license, during the Technology Term, to make,

         disparage such IMPCO Modifications and shall otherwise not use any of
         IMPCO's Trademarks in connection with the Tri-Shield Tank. The
         foregoing right and license may be exercised on behalf of Quantum by a
         third party. Subject to the foregoing license, IMPCO shall own all
         right, title and interest in and to the IMPCO Modifications. Within

         license, during the Technology Term, to make, have made, use, have
         used, sell, offer to sell, import, reproduce, distribute, perform and

         Confidential Information of Quantum) in connection with the Tri-Shield
         Tank, provided that IMPCO shall not disparage such Quantum
         Modifications. The foregoing right and license may be exercised on

             (viii) Royalties.

                    (A) IMPCO shall pay Quantum the following royalties in
         connection with the sale of IMPCO Tanks which include or incorporate
         one or more Quantum Modifications: two percent (2%) of net revenues
         actually received by IMPCO for the sale of such IMPCO Tanks. For
         purposes of this Section 2.1(b)(viii), "net revenues" refers to
         revenues actually received by IMPCO from the purchasers of such IMPCO
         Tanks less commissions paid or payable to third parties, royalties paid
         or payable to third parties, cost of goods, manufacturing costs,
         shipping and handling charges, any amounts attributable to fraud, taxes
         (sales, use, excise and other taxes), and amounts paid, payable,
         credited or to-be-credited for returns and exchanges. With respect to
         net revenues generated in foreign currency, the exchange rate used to
         determine royalties shall be the applicable exchange rate as set forth
         in the final edition of The Wall Street Journal for the business day
         immediately preceding the date on which payment in foreign currency was
         made by a third party to IMPCO. Net revenues attributable to such IMPCO
         Tanks which are bundled with other products shall be based upon the
         ratio of the average list prices for the applicable IMPCO Tank during
         the immediately preceding three (3) fiscal month period to the average
         list prices of the other products in the bundle during the immediately
         preceding three (3) fiscal month period, provided that, where there is
         no list price for a component, the average list price for such
         component shall be determined by IMPCO in good faith. IMPCO shall pay
         the royalties with respect to each of IMPCO's fiscal quarters within
         forty-five (45) days after the end of such fiscal quarter, or as soon
         as possible thereafter. Upon request by Quantum, IMPCO shall provide
         the basis for its calculation of the royalties due for such fiscal
         quarter.

                    (B) Quantum shall pay IMPCO the following royalties in
         connection with the sale of Tri-Shield Tanks manufactured, sold or
         distributed by Quantum which

                                       20

<PAGE>

         include or incorporate one or more IMPCO Modifications: two percent
         (2%) of net revenues actually received by Quantum for the sale of such
         tanks. For purposes of this Section 2.1(b)(viii), "net revenues" refers
         to revenues actually received by Quantum from the purchasers of such
         tanks less commissions paid or payable to third parties, royalties paid
         or payable to third parties, cost of goods, manufacturing costs,
         shipping and handling charges, any amounts attributable to fraud, taxes
         (sales, use, excise and other taxes), and amounts paid, payable,
         credited or to-be-credited for returns and exchanges. With respect to
         net revenues generated in foreign currency, the exchange rate used to
         determine royalties shall be the applicable exchange rate as set forth
         in the final edition of The Wall Street Journal for the business day
         immediately preceding the date on which payment in foreign currency was
         made by a third party to Quantum. Net revenues attributable to such
         tanks which are bundled with other products shall be based upon the
         ratio of the average list prices for such applicable tank during the
         immediately preceding three (3) fiscal month period to the average list
         prices of the other products in the bundle during the immediately
         preceding three (3) fiscal month period, provided that, where there is
         no list price for a component, the average list price for such
         component shall be determined by Quantum in good faith. Quantum shall
         pay the royalties with respect to each of Quantum's fiscal quarters
         within forty-five (45) days after the end of such fiscal quarter, or as
         soon as possible thereafter. Upon request by IMPCO, Quantum shall
         provide the basis for its calculation of the royalties due for such
         fiscal quarter.

             (ix) Enforcement of Reserved Technology Rights. During the
         Technology Term, IMPCO will have the right, but not the obligation, to
         take action to enforce its Intellectual Property Rights in connection
         with the Reserved Technology Rights against any third party that
         infringes or misappropriates such Reserved Technology Rights. If IMPCO
         declines to take any such action and Quantum wishes to take such
         action, IMPCO and Quantum will consult with each other to determine the
         course of action, if any, to be taken by Quantum in such circumstances.
         Upon IMPCO's written authorization to take action against such
         infringers, which may be withheld in IMPCO's sole discretion, Quantum
         may take the authorized action against such infringers. Quantum shall
         be solely responsible for all costs associated with any action taken by
         Quantum against infringers of the Intellectual Property Rights
         associated with the Reserved Technology Rights. In such circumstances,
         any damage that might be awarded to Quantum will, after deduction of
         actual costs of Quantum, be paid directly to IMPCO.

             (x)  Assignment. IMPCO may assign to one or more Affiliate(s) of
         IMPCO the right and license granted with respect to the Quantum
         Modifications pursuant to Section 2.1(b)(vii), provided that such
         Affiliate(s) agrees in writing to be bound by the applicable
         restrictions and to assume the applicable obligations set forth in
         Sections 2.1(b) and Section 2.16. Quantum may assign to one or more
         Affiliate(s) of Quantum the right and license granted with respect to
         the IMPCO Modifications pursuant to Section 2.1(b)(vi), provided that
         such Affiliate(s) agrees in writing to be bound by the applicable
         restrictions and to assume the applicable obligations set forth in
         Sections 2.1(b) and 2.16.

         (c) ORIGINAL ISSUANCE AND STOCK DIVIDEND TO IMPCO. On or prior to the
Distribution Date, Quantum shall issue to IMPCO as a stock dividend such number

             (i)  all transferable licenses, permits and authorizations issued
         by any Governmental Authority which relate primarily to the Quantum
         Business but which are held in the name of IMPCO or any member of the
         IMPCO Group, or in the name of any employee, officer, director,
         stockholder or agent of IMPCO or any such member, or otherwise, on
         behalf of a member of the Quantum Group, including but not limited to

         and

             (ii) all transferable licenses, permits and authorizations issued

         Quantum Business but which are held in the name of any member of the
         Quantum Group, or in the name of any employee, officer, director,
         stockholder, or agent of any such member, or otherwise, on behalf of a
         member of the Quantum Group, including but not limited to those
         licenses, permits and authorizations set forth on Schedule 2.1(f)(ii),
         shall be duly and validly transferred or caused to be transferred by
         Quantum to IMPCO or the appropriate member of the IMPCO Group.

         (g) TRANSFER OF AGREEMENTS. Without limiting the generality of the
obligations set forth in Section 2.1(a):

             (i)  IMPCO hereby agrees that, on or prior to the Distribution Date
         or as soon as reasonably practicable thereafter, subject to the
         limitations set forth in this Section

                                       22

<PAGE>

         2.1(g), it will, and it will cause each member of the IMPCO Group to,
         assign, transfer and convey to the appropriate member of the Quantum
         Group all of IMPCO's or such member of the IMPCO Group's respective
         right, title and interest in and to any and all Quantum Contracts.

                   (ii)  Quantum hereby agrees that, on or prior to the
         Distribution Date or as soon as reasonably practicable thereafter,
         subject to the limitations set forth in this Section 2.1(g), it will,
         and it will cause each member of the Quantum Group to, assign, transfer
         and convey to IMPCO or the appropriate member of the IMPCO Group all of
         Quantum's or such member of the Quantum Group's respective right, title
         and interest in and to any and all IMPCO Contracts.

                   (iii) Subject to the provisions of this Section 2.1(g), the
         Joint Contracts shall be assigned in part so that each party shall be
         entitled to the rights and benefits inuring to its business under each
         such agreement.

                   (iv)  The assignee of any agreement assigned, in whole or in
         part, hereunder (an "Assignee") shall assume and agree to pay, perform,
         and fully discharge all past, present and future obligations of the
         assignor under such agreement or, in the case of a partial assignment
         under paragraph (g)(iii), such Assignee's related portion of such
         obligations as determined in accordance with the terms of the relevant
         agreement, where determinable on the face thereof, and otherwise as
         determined in accordance with the practice of the parties prior to the
         Distribution.

                   (v)   Notwithstanding anything in this Agreement or any
         Ancillary Agreement to the contrary, neither this Agreement nor any
         Ancillary Agreement shall constitute an agreement to assign or an
         assignment of any agreement, in whole or in part, or any rights
         thereunder if the agreement to assign, attempt to assign or assignment,
         without the consent of a third party, would constitute a breach thereof
         or in any way adversely affect the rights of the assignor or Assignee
         thereof. Until such consent is obtained, or if an attempted assignment
         thereof would be ineffective or would adversely affect the rights of
         any party hereto so that the intended Assignee would not, in fact,
         receive all such rights, the parties will cooperate with each other in
         any arrangement designed to provide for the intended Assignee the
         benefits of, and to permit the intended Assignee to assume liabilities
         under, any such agreement.

                   (vi)  Without limiting the generality of the provisions of
         paragraph (g)(v) above:

                         (A) If the parties do not obtain a required consent to
         the assignment by IMPCO to Quantum of any Quantum Contract which
         contains provisions for the benefit of IMPCO protecting the
         confidentiality of proprietary information ("Confidentiality
         Provisions"), IMPCO shall, upon the request of Quantum and at Quantum's
         sole expense (including disbursements and costs of salaries, plus a
         fixed rate in the amount of thirty percent (30%) of such salaries to
         cover employee benefits, and all other out-of-pocket expenses incurred
         by IMPCO in connection therewith), promptly enforce any breaches by a
         third party of any such Confidentiality Provisions, and thereafter
         shall remit to

                                       23

<PAGE>

         Quantum any proceeds of any such enforcement efforts promptly after
         receipt thereof (after deduction therefrom of any enforcement expenses
         not theretofore reimbursed by Quantum). Quantum shall cooperate fully
         with and provide assistance to IMPCO in connection with the enforcement
         of any such Confidentiality Provisions.

                (B) If the parties do not obtain a required consent to the
         assignment by Quantum to IMPCO of any IMPCO Contract which
         Confidentiality Provisions for the benefit of Quantum, Quantum shall,
         upon the request of IMPCO and at IMPCO's sole expense (including
         disbursements and costs of salaries, plus a fixed rate in the amount of
         thirty percent (30%) of such salaries to cover employee benefits, and
         all other out-of-pocket expenses incurred by Quantum in connection
         therewith), promptly enforce any breaches by a third party of any such
         Confidentiality Provisions, and thereafter shall remit to IMPCO any
         proceeds of any such enforcement efforts promptly after receipt thereof
         (after deduction therefrom of any enforcement expenses not theretofore
         reimbursed by IMPCO). IMPCO shall cooperate fully with and provide
         assistance to Quantum in connection with the enforcement of any such
         Confidentiality Provisions.

                (C) If the parties do not obtain a required consent to the
         assignment by IMPCO to Quantum of any agreement with an independent
         contractor constituting a Quantum Contract which contains invention
         assignment provisions ("Invention Assignment Provisions") for the
         benefit of IMPCO, and if, in accordance with paragraph (v) above, the
         parties enter into an arrangement to provide Quantum the benefits of
         such Quantum Contract, then IMPCO shall, upon the request of Quantum
         and at Quantum's sole expense (including disbursements and costs of
         salaries, plus a fixed rate in the amount of thirty percent (30%) of
         such salaries to cover employee benefits, and all other out-of-pocket
         expenses incurred by IMPCO in connection therewith), promptly enforce
         any such Invention Assignment Provisions and promptly assign to Quantum
         all of IMPCO's rights to any such Technology assigned to IMPCO under
         any such Invention Assignment Provisions. Quantum shall cooperate fully
         with and provide assistance to IMPCO in connection with the enforcement
         of any such Invention Assignment Provisions.

                (D) If the parties do not obtain a required consent to the
         assignment by Quantum to IMPCO of any agreement with an independent
         contractor constituting an IMPCO Contract which contains Invention
         Assignment Provisions for the benefit of Quantum, and if, in accordance
         with paragraph (g)(v) above, the parties enter into an arrangement to
         provide IMPCO the benefits of such IMPCO Contract, then Quantum shall,
         upon the request of IMPCO and at IMPCO's sole expense (including
         disbursements and costs of salaries, plus a fixed rate in the amount of
         thirty percent (30%) of such salaries to cover employee benefits, and
         all other out-of-pocket expenses incurred by Quantum in connection
         therewith), promptly enforce any such Invention Assignment Provisions
         and promptly assign to IMPCO all of Quantum's rights to any such
         Technology assigned to Quantum under any such Invention Assignment
         Provisions. IMPCO shall cooperate fully with and provide assistance to
         Quantum in connection with the enforcement of any such Invention
         Assignment Provisions.

         (h) NOVATION OF ASSUMED QUANTUM LIABILITIES. Without limiting the
generality of the obligations set forth in Section 2.1(a):

             (i)  Each of IMPCO and Quantum, at the request of the other, shall
         use its reasonable best efforts to obtain, or to cause to be obtained,
         any consent, substitution, approval or amendment required to novate
         (including with respect to any contract with a Governmental Authority)
         or assign all obligations under agreements, leases, licenses and other
         obligations or liabilities of any nature whatsoever that constitute
         Quantum Liabilities, or to obtain in writing the unconditional
         prospective release of any and all obligations or liabilities arising
         from and after the Contribution Date of all parties to such
         arrangements other than any member of the Quantum Group, so that, in
         any such case, Quantum and its Subsidiaries will be solely responsible
         for such liabilities; provided, however, that none of IMPCO or Quantum
         shall be obligated to pay any consideration therefor to any third party
         from whom such consents, approvals, substitutions, amendments and
         prospective releases are requested if the consideration requested by
         any such third party exceeds 10% of the total amounts payable by or to
         Quantum under such contract. IMPCO and Quantum agree to enter into a
         novation agreement with the United States Government providing for the
         assignment of government contracts that are Quantum Contracts from
         IMPCO to Quantum substantially in the form of the novation agreement
         prescribed by the Federal Acquisition Regulation ("FAR") or upon such
         terms as may be reasonably requested by the federal government and to
         provide the documents prescribed by the FAR to be filed with such
         novation request.

             (ii) If IMPCO or Quantum is unable to obtain, or to cause to be
         obtained, any such required consent, approval, prospective release,
         substitution or amendment, the applicable member of the IMPCO Group
         shall continue to be bound by such agreements, leases, licenses and
         other obligations ("Unreleased IMPCO Liabilities") and, unless not
         permitted by law or the terms thereof, Quantum shall, as agent or
         subcontractor for IMPCO or such other person and where appropriate in
         the name thereof, as the case may be, pay, perform and discharge fully
         all the Unreleased IMPCO Liabilities from and after the Contribution
         Date. Quantum shall indemnify each IMPCO Indemnitee and hold each of
         them harmless from and against any Unreleased IMPCO Liabilities. IMPCO
         shall, without further consideration, pay and remit, or cause to be
         paid or remitted to Quantum promptly all money, rights and other
         consideration received by it or any member of its Group in respect of
         such performance (unless any such consideration is an IMPCO Asset). If
         and when any such consent, approval, prospective release, substitution
         or amendment shall be obtained or such agreement, lease, license or
         other rights or obligations shall otherwise become assignable or able
         to be novated, IMPCO shall thereafter assign, or cause to be assigned,
         all its rights, obligations and other liabilities thereunder or any
         rights or obligations of any member of its Group to Quantum without
         payment of further consideration and Quantum shall, without the payment
         of any further consideration, assume such rights and obligations.

         (i) NOVATION OF LIABILITIES OTHER THAN QUANTUM LIABILITIES. Without
limiting the generality of the obligations set forth in Section 2.1(a):

                                       25

<PAGE>

             (i)  Each of IMPCO and Quantum, at the request of the other, shall
         use its reasonable best efforts to obtain, or to cause to be obtained,
         any consent, substitution, approval or amendment required to novate or
         assign all obligations under agreements, leases, licenses and other
         obligations or liabilities of any nature whatsoever that do not
         constitute Quantum Liabilities, or to obtain in writing the
         unconditional prospective release of any and all obligations or
         liabilities arising from and after the Contribution Date of all parties
         to such arrangements other than any member of the IMPCO Group, so that,
         in any such case, the members of the IMPCO Group will be solely
         responsible for such liabilities; provided, however, that neither IMPCO
         nor Quantum shall be obligated to pay any consideration therefor to any
         third party from whom such consents, approvals, substitutions,
         amendments and prospective releases are requested.

             (ii) If IMPCO or Quantum is unable to obtain, or to cause to be
         obtained, any such required consent, approval, prospective release,
         substitution or amendment, the applicable member of the Quantum Group
         shall continue to be bound by such agreements, leases, licenses and
         other obligations ("Unreleased Quantum Liabilities") and, unless not
         permitted by law or the terms thereof, IMPCO shall cause a member of
         the IMPCO Group, as agent or subcontractor for such member of the
         Quantum Group and where appropriate in the name thereof, to pay,
         perform and discharge fully all the Unreleased Quantum Liabilities from
         and after the Contribution Date. IMPCO shall indemnify each Quantum
         Indemnitee and hold each of them harmless from and against any
         Unreleased Quantum Liabilities. Quantum shall cause each member of the
         Quantum Group without further consideration, to pay and remit, or cause
         to be paid or remitted, to IMPCO or to another member of the IMPCO
         Group specified by IMPCO promptly all money, rights and other
         consideration received by it or any member of the Quantum Group in
         respect of such performance (unless such consideration is a Quantum
         Asset). If and when any such consent, approval, prospective release,
         substitution or amendment shall be obtained or such agreement, lease,
         license or other rights or obligations shall otherwise become
         assignable or able to be novated, Quantum shall promptly assign, or
         cause to be assigned, all its rights, obligations and other liabilities
         thereunder or any rights or obligations of any member of the Quantum
         Group to IMPCO or to another member of the IMPCO Group specified by
         IMPCO without payment of further consideration and IMPCO, without the
         payment of any further consideration shall, or shall cause such other
         member of the IMPCO Group to, assume such rights and obligations.

         (j) CONSENTS. The parties hereto shall use their commercially
reasonable efforts to obtain required consents to the transfer and/or assignment
of licenses, permits and authorizations of Governmental Authorities and of
agreements hereunder.

         (k) DELIVERY OF SHARES TO AGENT. IMPCO shall deliver to the
distribution agent (the "Agent") the share certificate or certificates
representing the Quantum Common Shares which are to be distributed to the
holders of IMPCO Common Stock in the Distribution and shall instruct the Agent
to distribute, on or as soon as practicable following the Distribution Date,
certificates representing such Quantum Common Shares to holders of record of
shares of IMPCO Common Stock on the Distribution Record Date as further
contemplated by the

                                       26

<PAGE>

Information Statement and herein. Quantum shall provide all share certificates
and other documents that the Agent shall require in order to effect the
Distribution.

         (l) FRACTIONAL SHARES. As soon as practicable after the Distribution
Date, IMPCO shall direct the Agent to determine the number of whole shares and
fractional shares (if any) of Quantum Common Stock allocable to each holder of
record or beneficial owner of IMPCO Common Stock as of the Distribution Record
Date, to aggregate all such fractional shares and sell the whole shares obtained
thereby in open market transactions or otherwise, in each case at then
prevailing trading prices (and in each case in accordance with the rules,
regulations and interpretations of the Commission), and to cause to be
distributed to each such holder or for the benefit of each such beneficial
owner, in lieu of any fractional share, such holder's or owner's ratable share
of the proceeds of such sale, after making appropriate deductions of the amount
required to be withheld for federal income tax purposes and after deducting an
amount equal to all brokerage charges, commissions and transfer taxes attributed
to such sale.

         (m) CERTAIN LIABILITIES. For purposes of this Agreement, including
Article III hereof, Quantum agrees with IMPCO that:

             (i)  any and all liabilities arising from or based upon
         misstatements in or omissions from the Form 10 filed by Quantum shall
         be deemed to be Quantum Liabilities and not IMPCO liabilities;
         provided, however, Quantum will not be liable to the extent that any
         such liability arises out of or is based upon any misstatement in or
         omission from the Form 10 made therein in reliance upon and in
         conformity with written information furnished to Quantum by or on
         behalf of IMPCO specifically for inclusion therein, it being understood
         that the only such information is that set forth in Schedule
         1.1(pp)(iii).

             (ii) except as otherwise provided in this Agreement or the
         Ancillary Agreements, any liabilities not specifically allocated to
         Quantum pursuant to this Agreement (including the schedules hereto) or
         the Ancillary Agreements (including all schedules thereto) shall be
         deemed to be IMPCO Liabilities and not Quantum Liabilities.

         (n) OTHER TRANSACTIONS. On or prior to the Distribution Date, each of
IMPCO and Quantum shall consummate those other transactions in connection with
the Distribution that are contemplated by the Form 10 in order to implement the
Distribution. After the Distribution Date, each of IMPCO and Quantum will
exercise good faith commercially reasonable efforts to consummate as promptly as
practicable all other transactions which must be consummated in order fully to
complete the Contribution, the Distribution and any of the transactions
contemplated hereby or by any of the Ancillary Agreements.

         SECTION 2.2 IMPCO BOARD ACTION; CONDITIONS PRECEDENT TO THE
DISTRIBUTION. IMPCO's Board of Directors shall, in its sole discretion,

<PAGE>

PROVIDED, that the satisfaction of such conditions shall not create any
obligation on the part of IMPCO to effect the Distribution or in any way limit
IMPCO's power of termination set forth in Section 9.11 or alter the consequences
of any such termination from those specified in such Section.

       SECTION 2.3 INTERCOMPANY ACCOUNTS.

       (a) From the date of this Agreement, and for a period of two years after

indirectly, to be solicited for employment or employ or cause or authorize,
directly or indirectly, to be employed or engaged as an employee, for or on
behalf of itself or any other person, any person who is currently, or was, less
than 90 days prior to the date of this Agreement, an executive officer, senior
manager (or the equivalent thereof), executive vice president or employee of the
Quantum Business, Quantum or any of Quantum's Subsidiaries, without Quantum's
prior written approval.

       SECTION 2.7 FURTHER ASSURANCES. In case at any time after the Effective
Time any further action is reasonably necessary or desirable to carry out the
purposes of this Agreement and the Ancillary Agreements, the proper officers of
each party to this Agreement shall take all such necessary action. Without
limiting the foregoing, IMPCO and Quantum shall use their commercially
reasonable efforts promptly to obtain all consents and approvals, to enter into
all amendatory agreements and to make all filings and applications that may be
required for the consummation of the transactions contemplated by this Agreement
and the Ancillary Agreements, including, without limitation, all applicable
governmental and regulatory filings.

       SECTION 2.8 LIMITED REPRESENTATIONS OR WARRANTIES. EACH OF THE PARTIES
HERETO AGREES THAT IMPCO DOES NOT MAKE, IN THIS AGREEMENT OR IN ANY OTHER
AGREEMENT OR DOCUMENT CONTEMPLATED BY THIS AGREEMENT OR OTHERWISE, AND IMPCO
EXPRESSLY DISCLAIMS, ANY REPRESENTATIONS OR WARRANTIES WHATSOEVER, WHETHER
EXPRESS, IMPLIED, STATUTORY OR OTHERWISE, INCLUDING WITHOUT LIMITATION
WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE,
NON-INFRINGEMENT OF THIRD PARTY RIGHTS, TITLE, VALUE, AND ANY WARRANTIES ARISING
OUT OF A COURSE OF PERFORMANCE, DEALING OR TRADE USAGE, INCLUDING WITHOUT
LIMITATION ANY WARRANTIES RELATING IN ANY MANNER TO THE QUANTUM ASSETS, AND
RELATED RIGHTS AND PRIVILEGES BEING TRANSFERRED HEREBY. IT IS ALSO AGREED THAT,
NOTWITHSTANDING ANYTHING TO THE CONTRARY OTHERWISE EXPRESSLY PROVIDED IN THE
RELEVANT CONVEYANCING AND ASSUMPTION INSTRUMENT, ALL QUANTUM ASSETS TRANSFERRED
TO THE QUANTUM PARTIES OR RETAINED BY THE QUANTUM PARTIES SHALL BE TRANSFERRED
OR RETAINED, AS THE CASE MAY BE, ON AN "AS IS, WHERE IS" BASIS AND THAT (SUBJECT
TO SECTION

                                       30

<PAGE>

2.7) THE QUANTUM PARTIES SHALL BEAR THE ECONOMIC AND LEGAL RISK THAT THE QUANTUM
PARTIES' USE OF OR TITLE TO ANY SUCH QUANTUM ASSETS SHALL BE OTHER THAN GOOD AND
MARKETABLE AND FREE FROM ENCUMBRANCES. Similarly, each party hereto agrees that,
notwithstanding anything to the contrary otherwise expressly provided in the
relevant Conveyancing and Assumption Instrument, no party hereto represents or
warrants in any way that the obtaining of any consents or approvals, the
execution and delivery of any amendatory agreements and the making of any
filings or applications contemplated by this Agreement will satisfy the
provisions of any or all applicable agreements or the requirements of any or all
applicable laws or judgments, it being agreed that the party to which any Assets
are transferred shall bear the economic and legal risk that any necessary
consents or approvals are not obtained or that any requirements of laws or
judgments are not complied with.

       SECTION 2.9 GUARANTEES.

       (a) Except as otherwise specified herein or in any Ancillary Agreement,
Quantum and IMPCO shall use their commercially reasonable efforts to have, on or
prior to the Contribution Date, or as soon as practicable thereafter, IMPCO and
any member of the IMPCO Group removed as guarantor of or obligor for any Quantum
Liability, including, without limitation, in respect of those guarantees set
forth on Schedule 2.9(a) to the extent that they relate to Quantum Liabilities.

       (b) Except as otherwise specified herein or in any Ancillary Agreement,
Quantum and IMPCO shall use their commercially reasonable efforts to have, on or
prior to the Contribution Date, or as soon as practicable thereafter, Quantum
and any member of the Quantum Group removed as guarantor of or obligor for any
IMPCO Liability, including, without limitation, in respect of those guarantees
set forth on Schedule 2.9(b) to the extent that they relate to IMPCO
Liabilities.

       (c) If Quantum or IMPCO is unable to obtain, or to cause to be obtained,
any such required removal as set forth in clauses (a) or (b) of this Section
2.9, the applicable guarantor or obligor shall continue to be bound as such and,
unless not permitted by law or the terms thereof, the relevant beneficiary shall
or shall cause one of its Subsidiaries, as agent or subcontractor for such
guarantor or obligor to pay, perform and discharge fully all the obligations or
other liabilities of such guarantor or obligor thereunder from and after the
Distribution Date. Either party shall indemnify and hold harmless the other
party for any and all liabilities incurred in connection with this Section 2.9.

       (d) Each party agrees and covenants that if Quantum or IMPCO is unable to
obtain, or to cause to be obtained, any such required removal as set forth in
clauses (a) or (b) of this Section 2.9:

           (i) the relevant beneficiary will use its commercially reasonable
       efforts to ensure that the applicable guarantor will incur no liability
       under the obligation guarantied or other credit support provided by the
       applicable guarantor;

                                       31

<PAGE>

                (ii)  the relevant beneficiary will perform and be bound by all
         covenants set forth in the instrument setting forth the relevant
         guaranty; and

                (iii) that, notwithstanding anything to the contrary herein or
         in any Ancillary Agreement, any and all fees and costs incurred by
         either party in connection with the relevant guaranty or other credit
         support provided by the applicable guarantor and the pursuit of the
         independent line of credit will be borne by the relevant beneficiary.

         SECTION 2.10 WITNESS SERVICES. At all times from and after the
Distribution Date, each of IMPCO and Quantum shall use their commercially
reasonable efforts to make available to the other, upon reasonable written
request, its and its Subsidiaries' officers, directors and employees as
witnesses to the extent that (i) such persons may reasonably be required in
connection with the prosecution or defense of any Action in which the requesting
party may from time to time be involved relating to (A) the operation of the
Quantum Business or the IMPCO Business prior to the Effective Time or (B) the
Reserved Technology Rights, and (ii) there is no conflict in the Action between
the requesting party and IMPCO or Quantum as applicable. A party providing
witness services to the other party under this Section shall be entitled to
receive from the recipient of such services, upon the presentation of invoices
therefor, payments for such amounts, relating to disbursements and other
out-of-pocket expenses (which shall be deemed to exclude the costs of salaries
and benefits of employees who are witnesses), as may be reasonably incurred in
providing such witness services.

         SECTION 2.11 TAX AND OTHER MATTERS.

         (a) (i) IMPCO shall comply and shall cause its Subsidiaries to comply
with and otherwise not take action inconsistent with each representation and
statement made to Morrison & Foerster LLP in connection with the request by
IMPCO for an opinion in respect of the Distribution as to certain federal income
tax aspects of the Distribution, and (ii) at least until three years after the
Distribution Date, IMPCO will maintain its status as a company engaged in the
active conduct of a trade or business, within the meaning of Section 355(b) of
the Code.

         (b) (i) Quantum shall comply and shall cause its Subsidiaries to comply
with and otherwise not take action inconsistent with each representation and
statement made to Morrison & Foerster LLP in connection with the request by
IMPCO for an opinion in respect of the Distribution as to certain federal income
tax aspects of the Distribution, and (ii) at least until three years after the
Distribution Date, Quantum will maintain its status as a company engaged in the
active conduct of a trade or business, within the meaning of Section 355(b) of
the Code.

         (c) During the three-year period beginning on the Distribution Date,
Quantum will not (i) merge, consolidate or combine with or into any other
corporation, (ii) liquidate or partially liquidate, (iii) sell or transfer all
or substantially all of its assets (within the meaning of Rev. Proc. 77-37,
1977-2 C.B. 568) in a single transaction or series of related transactions, (iv)
redeem or otherwise repurchase any Quantum Common Shares (other than as
described in Section 4.05(1)(b) of Rev. Proc. 96-30, 1996-1 C.B. 696), or (v)
subject to Section 2.11(d) below, take any other action or actions which could
reasonably be expected have the effect of causing Section 355(e) of the Code to
apply to the Distribution, unless prior to taking such action

                                       32

<PAGE>

Quantum has obtained (and provided to IMPCO) a written opinion of a law firm
reasonably acceptable to IMPCO, or a ruling from the Internal Revenue Service,
that such action or actions will not result in the Quantum Common Shares failing
to qualify as qualified property for purposes of Section 355(c)(2) or 361(c)(2)
of the Code by reason of Section 355(e) of the Code

         (d) Quantum shall not be required to obtain a legal opinion or ruling
from the Internal Revenue Service required pursuant to Section 2.11(c) above in
connection with (i) the issuance by Quantum of shares of its Series A or Series
B common stock to General Motors Corporation or an affiliate thereof (or the
issuance of Quantum Common Stock upon conversion thereof) pursuant to the terms
of the Corporate Alliance Agreement and the Stock Transfer Agreement between
Quantum and General Motors, each dated June 12, 2001 and amended as of July 19,
2002 (collectively, the "GM Issuances"), or (ii) the offer and sale by Quantum
of common stock in its first public offering following the Distribution Date
pursuant to a registration statement under the Securities Act of 1933, as
amended (the "IPO"). Nothing in this Section 2.11(d) shall limit the obligation
of Quantum to indemnify IMPCO pursuant Section 2.11(e) below in connection with
the GM Issuances or the IPO.

         (e) Notwithstanding anything to the contrary herein or in the Ancillary
Agreements, if IMPCO or Quantum (or any of their respective Subsidiaries) fails
to comply with any of its obligations under Sections 2.11(a) through (and
including) 2.11(c) above or takes or fails to take any action on or after the
Distribution Date, and such action or failure to comply, action or omission
contributes to a determination that (i) the Distribution fails to qualify under
Section 355(a) of the Code or (ii) the Quantum Common Shares fail to qualify as
qualified property for purposes of Section 355(c)(2) or 361(c)(2) of the Code by
reason of Section 355(e) of the Code, then such party shall indemnify and hold
harmless the other party, each member of the consolidated group of which the
other party is a member and the stockholders of either party from and against
any and all Taxes imposed upon or incurred by such other party, any member of
its group or any stockholder of either party as a result of the failure of the
Distribution to qualify under Section 355(a) of the Code or the application of
Section 355(e) of the Code. The obligation of Quantum to indemnify IMPCO
pursuant to the preceding sentence shall not be affected by the delivery of any
legal opinion or ruling from the Internal Revenue Service under Section 2.11(c).

         SECTION 2.12 TRANSFERS NOT EFFECTED PRIOR TO THE DISTRIBUTION;
TRANSFERS DEEMED EFFECTIVE AS OF THE DISTRIBUTION DATE. To the extent that any
transfers contemplated by this Article II shall not have been consummated on or
prior to the Distribution Date, the parties shall cooperate to effect such
transfers as promptly following the Distribution Date as shall be practicable.
Nothing herein shall be deemed to require the transfer of any assets or the
assumption of any liabilities which by their terms or operation of law cannot be
transferred; provided, however, that the parties hereto and their respective
Subsidiaries shall cooperate to seek to obtain any necessary consents or
approvals for the transfer of all assets and liabilities contemplated to be
transferred pursuant to this Article II. In the event that any such transfer of
assets or liabilities has not been consummated, from and after the Distribution
Date, the party retaining such asset or liability shall hold such asset in trust
for the use and benefit of the party entitled thereto (at the expense of the
party entitled thereto) or retain such liability for the account of the party by
whom such liability is to be assumed pursuant hereto, as the case may

                                       33

<PAGE>

be, and take such other action as may be reasonably requested by the party to
whom such asset is to be transferred, or by whom such liability is to be
assumed, as the case may be, in order to place such party, insofar as is
reasonably possible, in the same position as would have existed had such asset
or liability been transferred as contemplated hereby. As and when any such asset
or liability becomes transferable, such transfer shall be effected forthwith.
The parties agree that, as of the Contribution Date, each party hereto shall be
deemed to have acquired complete and sole beneficial ownership over all of the
assets, together with all rights, powers and privileges incident thereto, and
shall be deemed to have assumed in accordance with the terms of this Agreement
all of the liabilities, and all duties, obligations and responsibilities
incident thereto, which such party is entitled to acquire or required to assume
pursuant to the terms of this Agreement.

     SECTION 2.13 CONVEYANCING AND ASSUMPTION INSTRUMENTS. In connection with
the transfers of assets and the assumptions of liabilities contemplated by this
Agreement, the parties shall execute, or cause to be executed by the appropriate
entities, the Conveyancing and Assumption Instruments in substantially the form
contemplated hereby. Without limiting the generality of the foregoing, the
transfer of capital stock shall be effected by means of delivery of stock
certificates and executed stock powers and notation on the stock record books of
the legal entities involved, or by such other means as may be required in any
non-U.S. jurisdiction to transfer title to stock and, to the extent required by
applicable law, by notation on public registries. In the event that any
provisions of any Conveyancing and Assumption Instrument is inconsistent or
contradictory to the terms and conditions of this Agreement, the terms and
conditions of this Agreement shall control.

     SECTION 2.14 ANCILLARY AGREEMENTS. Prior to the Distribution Date, each of
IMPCO and Quantum shall enter into, and/or (where applicable) shall cause
members of the IMPCO Group or the Quantum Group, as applicable, to enter into,
the Ancillary Agreements and any other agreements in respect of the Distribution
reasonably necessary or appropriate in connection with the transactions
contemplated hereby and thereby.

     SECTION 2.15 CORPORATE NAMES.

     (a)  Except as otherwise specifically provided in any Ancillary Agreement:

          (i)  As soon as reasonably practicable after the Distribution Date but
     in any event within six months thereafter, IMPCO will, at its own expense,
     remove (or, if necessary, on an interim basis, cover up) any and all
     exterior signs and other identifiers located on any of its property or
     premises or on the property or premises used by it or its Subsidiaries
     (except property or premises to be shared with Quantum or its Subsidiaries
     after the Distribution) which use or display trade names, trademarks and
     logos of Quantum, including without limitation "Quantum" and any other
     Quantum trade name, trademark or logo (collectively, "Quantum Marks").

          (ii) As soon as reasonably practicable after the Distribution Date but
     in any event within six months thereafter, IMPCO will, and will cause its
     Subsidiaries to, remove from all letterhead, envelopes, invoices and other
     communications media of any

                                       34

<PAGE>

     kind, other than materials already in the possession of customers prior to
     the Effective Time, all references to any Quantum Marks. Neither IMPCO nor
     its Subsidiaries shall use or display any Quantum Marks or portions
     thereof, other than with respect to materials already in the possession of
     customers prior to the Effective Time, without the prior written consent of
     Quantum, except as permitted by applicable law.

     (b)  Except as otherwise specifically provided in any Ancillary Agreement:

          (i)   As soon as reasonably practicable after the Distribution Date
     but in any event within six months thereafter, Quantum will, at its own
     expense, remove (or, if necessary, on an interim basis, cover up) any and
     all exterior signs and other identifiers located on any of their respective
     property or premises owned or used by them or their respective Subsidiaries
     (except property or premises to be shared with IMPCO or its Subsidiaries
     after the Distribution) which use or display trade names, trademarks and
     logos of IMPCO, including without limitation "IMPCO Technologies" and
     "IMPCO," and any other IMPCO trade name, trademark or logo (collectively,
     "IMPCO Marks").

          (ii)  As soon as reasonably practicable after the Distribution Date
     but in any event within six months thereafter, Quantum will, and will cause
     its respective Subsidiaries to, remove from all letterhead, envelopes,
     invoices and other communications media of any kind, other than materials
     already in the possession of customers prior to the Effective Time, all
     references to any IMPCO Marks. Neither Quantum nor any of its Subsidiaries
     shall use or display any IMPCO Marks or portions thereof, other than with
     respect to materials already in the possession of customers prior to the
     Effective Time, without the prior written consent of IMPCO except as
     permitted by applicable law and as expressly provided in Section
     2.15(b)(iii).

          (iii) Subject to the trademark guidelines established by IMPCO from
     time to time, and subject to IMPCO's approval of samples of each use of an
     IMPCO Mark, Effective as of the Effective Time, IMPCO agrees to grant to
     Quantum a non-sublicenseable, non-transferable, revocable, royalty-free,
     worldwide right and license to use and display the IMPCO Marks as they
     appear on existing service parts manufactured by IMPCO prior to the
     Contribution Date and which are serviced by Quantum after the Contribution
     Date.

     SECTION 2.16 JOINT BUSINESS OPPORTUNITIES; NON-COMPETITION; PROTECTION OF
INFORMATION.

     (a)  IMPCO and Quantum may pursue joint business opportunities to enhance
customer value, on terms and conditions as may be agreed by the parties after
the date hereof. The parties acknowledge and agree that nothing in this Section
2.16(a) shall create a binding obligation on IMPCO or Quantum to enter into or
pursue any such business opportunity.

     (b)  IMPCO hereby covenants and agrees that none of the members of the
IMPCO Group will, between the Effective Time and the third anniversary of the
Effective Time (the "Restricted Period"):

                                       35

<PAGE>

          (i)   engage in or carry on any business in the United States or
     elsewhere in whatever form which would be directly in competition with any
     Quantum Business as such businesses are conducted by the Quantum Group in
     the Quantum Markets at the Effective Time;

          (ii)  engage in or carry on any business in the United States or
     elsewhere in whatever form, directly or indirectly, with competitors of
     Quantum set forth in Schedule 2.16(b)(ii) or their respective subsidiaries
     ("Quantum Named Competitors"); and

          (iii) engage in or carry on any business in the United States or
     Canada in whatever form, directly or indirectly, with OEM customers of
     Quantum set forth in Schedule 2.16(b)(iii) or their respective subsidiaries
     ("Quantum Named OEM Customers").

     The parties acknowledge and agree that neither (i) IMPCO's exercise of the
Reserved Technology Rights and the use, manufacture, sale, distribution, and
other commercial exploitation of the Tri-Shield Tank in the IMPCO Market,
pursuant to Section 2.1(b)(i), nor (ii) the transfer of employees from the IMPCO
Group to Quantum prior to the Effective Time, shall constitute a breach of this
Section 2.16(b).

     (c)  Quantum hereby covenants and agrees that none of the members of the
Quantum Group will, during the Restricted Period:

          (i)   engage in or carry on any business in the United States or
     elsewhere in whatever form which would be directly in competition with any
     IMPCO Business as such businesses are conducted by the IMPCO Group in the
     IMPCO Markets at the Effective Time; and

          (ii)  engage in or carry on any business in the United States or
     elsewhere in whatever form, directly or indirectly, with competitors of
     IMPCO set forth in Schedule 2.16(c) or their respective subsidiaries
     ("IMPCO Named Competitors").

     The parties acknowledge and agree that neither (i) Quantum's use,
manufacture, sale, distribution, and other commercial exploitation of the
Tri-Shield Tank, pursuant to Section 2.1(b)(ii), nor (ii) the transfer of
employees from the IMPCO Group to Quantum prior to the Effective Time, shall
constitute a breach of this Section 2.16(c).

     (d)  Each party acknowledges that the other party and its respective
Subsidiaries would suffer irreparable harm if it were to breach the provisions
of this Section 2.16 and that any remedy at law for any such breach is and will
be insufficient and inadequate, and that the aggrieved party shall be entitled
to equitable relief, including by way of temporary and permanent injunction,
without the necessity of posting bond or proving actual damages, in addition to
any remedies the aggrieved party may have at law.

                                       36

<PAGE>

         (e) Notwithstanding anything to the contrary in Sections 2.16(b) or
2.16(c) above, nothing in this Section 2.16 shall in any way restrict or
preclude either party or any of its respective Affiliates from: (i) as part of a
bona fide transaction, merging or consolidating with, acquiring all or
substantially all the assets of, selling all or substantially all of its assets
to, or entering into a similar transaction with, any person, including persons
whose primary business is in direct competition with the other party's business
conducted in the United States and elsewhere as of the Effective Time, or (ii)
acquiring ownership up to one percent (1%) of any class of securities of any
corporation or other entity having a class of securities registered under the
Securities Exchange Act of 1934, as amended.

         (f) The invalidity or non-enforceability of any provision of this
Section 2.16 in any respect shall not affect the validity or enforceability of
the other provisions of this Section 2.16 in any other respect or of any other
provisions of this Agreement. In the event that any provision of this Section
2.16 shall be held invalid or unenforceable by a court of competent jurisdiction
by reason of the geographic or business scope or the duration thereof, such
invalidity or unenforceability shall attach only to the scope or duration of
such provision and shall not affect or render invalid or unenforceable any other
provision of this Agreement, and, to the fullest extent permitted by law, this
Agreement shall be construed as if the geographic or business scope or the
duration of such provision had been more narrowly drafted so as not to be
invalid or unenforceable.

         (g) Each of IMPCO and Quantum acknowledge and agree that the covenants
and agreements contained in this Section 2.16 have been negotiated in good faith
by each of them, and are reasonable and not more restrictive or broader than
necessary to protect the interests of each of IMPCO and Quantum in the IMPCO
Business and the Quantum Business, respectively, and would not achieve their
intended purpose if they were on different terms or for periods of time shorter
than the periods of time provided herein or applied in more restrictive
geographical and business line areas than are provided herein.

         SECTION 2.17 ADJUSTMENT OF IMPCO WARRANTS.

         (a) As of the Distribution Date, each warrant to purchase IMPCO Common
Stock that is outstanding as of the Distribution Record Date and not exercised
prior to the Distribution Date (each an "IMPCO Warrant") shall be adjusted as
set forth in this Section 2.17. Each IMPCO Warrant shall be converted, as of the
Distribution Date, into two warrants: a warrant (the "IMPCO Adjusted Warrant")
to purchase the same number of shares of IMPCO Common Stock covered by the IMPCO
Warrant and as to which the IMPCO Warrant has not been exercised as of the
Distribution Date and a warrant (the "Quantum Warrant") to purchase a number of
shares of Quantum Common Stock equal to the IMPCO Warrant times a fraction, the
numerator of which is the total number of shares of Quantum Common Stock
distributed to IMPCO stockholders in the Distribution and the denominator of
which is the total number of shares of IMPCO Common Stock outstanding on
Distribution Record Date. The terms of the IMPCO Adjusted Warrant and the
Quantum Warrant (other than the exercise price and the number of shares) shall
be substantially the same as the IMPCO Warrant.

                                       37

<PAGE>

         (b) The exercise prices per share for each IMPCO Adjusted Warrant and
the Quantum Warrant shall be established, as set forth in Schedule 2.17(b)
hereto, in a manner so that: (a) the aggregate "intrinsic value" (i.e. the
market value of the stock underlying the warrant, less the exercise price of
such warrant, multiplied by the number of shares then covered by such warrant)
after the Distribution of the IMPCO Adjusted Warrant plus the Quantum Warrant is
not greater than the intrinsic value of the related IMPCO Warrant immediately
prior to the Distribution, and (b) the ratio of the exercise price per warrant
to the market value per share after the Distribution is not lower than the ratio
of the exercise price of the IMPCO Warrant to the market value per share of
IMPCO Common Stock immediately prior to the Distribution. The determination of
the exercise prices for each IMPCO Adjusted Warrant and Quantum Warrant shall be
made by IMPCO as advised by its professional advisors.

         (c) The Quantum Warrants to be granted pursuant to this Section 2.17
shall be issued by Quantum as soon as practicable following the Distribution
Date, and Quantum shall take all corporate action and make all required filings
under applicable state blue sky laws and the Securities Act to (i) issue the
Quantum Warrants as required under this Section 2.17 and (ii) to register or
qualify the shares of Quantum Common Stock underlying the Quantum Warrants so
that the shares of Quantum Common Stock acquired upon exercise of each Quantum
Warrant may be resold under the Securities Act (except for shares acquired by
Affiliates of Quantum) and each applicable state's blue sky laws, subject in
each case to the receipt by Quantum of investment representations and other
information from the holders of the IMPCO Warrants reasonably necessary to
effect such registration or qualification.

                                  ARTICLE III

                                 INDEMNIFICATION

         SECTION 3.1 INDEMNIFICATION BY IMPCO. Except as otherwise specifically
set forth in any provision of this Agreement or of any Ancillary Agreement,
IMPCO shall indemnify, defend and hold harmless the Quantum Indemnitees from and
against any and all Indemnifiable Losses of the Quantum Indemnitees arising out
of, by reason of or otherwise in connection with the IMPCO Liabilities or
alleged IMPCO Liabilities, including any breach by IMPCO of any provision of
this Agreement or any Ancillary Agreement.

         SECTION 3.2 INDEMNIFICATION BY QUANTUM. Except as otherwise
specifically set forth in any provision of this Agreement or of any Ancillary
Agreement, Quantum shall indemnify, defend and hold harmless the IMPCO
Indemnitees from and against any and all Indemnifiable Losses of the IMPCO
Indemnitees arising out of, by reason of or otherwise in connection with the
Quantum Liabilities or alleged Quantum Liabilities, including any breach by
Quantum of any provision of this Agreement or any Ancillary Agreement.

<PAGE>

         SECTION 3.3 PROCEDURES FOR INDEMNIFICATION.

         (a) THIRD PARTY CLAIMS.

             (i)  If a claim or demand is made against an IMPCO Indemnitee or a
         Quantum Indemnitee (each, an "Indemnitee") by any person who is not a
         party to this Agreement (a "Third Party Claim") as to which such
         Indemnitee is entitled to indemnification pursuant to this Agreement,
         such Indemnitee shall notify the party which is or may be required
         pursuant to this Agreement to make such indemnification (the
         "Indemnifying Party") in writing, and in reasonable detail, of the
         Third Party Claim promptly (and in any event within fifteen (15)
         business days) after receipt by such Indemnitee of written notice of
         the Third Party Claim; provided, however, that failure to give such
         notification shall not affect the indemnification provided hereunder
         except to the extent the Indemnifying Party shall have been actually
         prejudiced as a result of such failure (except that the Indemnifying
         Party shall not be liable for any expenses incurred during the period
         in which the Indemnitee failed to give such notice). Thereafter, the
         Indemnitee shall deliver to the Indemnifying Party, promptly (and in
         any event within five (5) business days) after the Indemnitee's receipt
         thereof, copies of all notices and documents (including court papers)
         received by the Indemnitee relating to the Third Party Claim.

             (ii) If a Third Party Claim is made against an Indemnitee, the
         Indemnifying Party shall be entitled to participate in the defense
         thereof and, if it so chooses and acknowledges in writing its
         obligation to indemnify the Indemnitee therefor, to assume the defense
         thereof with counsel selected by the Indemnifying Party; provided that
         such counsel is not reasonably objected to by the Indemnitee. Should
         the Indemnifying Party so elect to assume the defense of a Third Party
         Claim, the Indemnifying Party shall, within thirty 30 days (or sooner
         if the nature of the Third Party Claim so requires), notify the
         Indemnitee of its intent to do so, and the Indemnifying Party shall
         thereafter not be liable to the Indemnitee for legal or other expenses
         subsequently incurred by the Indemnitee in connection with the defense
         thereof; provided, that such Indemnitee shall have the right to employ
         counsel to represent such Indemnitee if, in such Indemnitee's
         reasonable judgment, a conflict of interest between such Indemnitee and
         such Indemnifying Party exists in respect of such claim which would
         make representation of both such parties by one counsel inappropriate,
         and in such event the fees and expenses of such separate counsel shall
         be paid by such Indemnifying Party. If the Indemnifying Party assumes
         such defense, any Indemnitee shall have the right to participate in the
         defense thereof and to employ counsel, subject to the proviso of the
         preceding sentence, at its own expense, separate from the counsel
         employed by the Indemnifying Party, it being understood that (A) the
         Indemnifying Party shall control such defense and (B) the Indemnifying
         Party shall not, in respect of the legal expenses of any Indemnified
         Party in connection with any proceeding or related proceedings in the
         same jurisdiction, be liable for the fees and expenses of more than one
         separate firm for all such Indemnified Parties. The Indemnifying Party
         shall be liable for the fees and expenses of counsel employed by the
         Indemnitee for any period during which the Indemnifying Party has
         failed to assume the defense thereof (other than during the period
         prior to the time the Indemnitee shall have given notice of the Third
         Party Claim as provided above). If the Indemnifying Party so elects to
         assume the defense of any Third Party Claim, all of the Indemnitees
         shall, at

                                       39

<PAGE>

         the expense of the Indemnifying Party, cooperate with the Indemnifying
         Party in the defense or prosecution thereof, including by providing or
         causing to be provided, Records and witnesses as soon as reasonably
         practicable after receiving any request therefor from or on behalf of
         the Indemnifying Party.

               (iii)  If the Indemnifying Party acknowledges in writing
         responsibility for a Third Party Claim, then in no event will the
         Indemnitee admit any liability with respect to, or settle, compromise
         or discharge, any Third Party Claim without the Indemnifying Party's
         prior written consent; provided, however, that the Indemnitee shall
         have the right to settle, compromise or discharge such Third Party
         Claim without the consent of the Indemnifying Party if the Indemnitee
         releases the Indemnifying Party from its indemnification obligation
         hereunder with respect to such Third Party Claim and such settlement,
         compromise or discharge would not otherwise adversely affect the
         Indemnifying Party. If the Indemnifying Party acknowledges in writing
         liability for a Third Party Claim, the Indemnitee will agree to any
         settlement, compromise or discharge of a Third Party Claim that the
         Indemnifying Party may recommend and that by its terms obligates the
         Indemnifying Party to pay the full amount of the liability in
         connection with such Third Party Claim and releases the Indemnitee
         completely in connection with such Third Party Claim and that would not
         otherwise adversely affect the Indemnitee; provided, however, that the
         Indemnitee may refuse to agree to any such settlement, compromise or
         discharge if the Indemnitee agrees that the Indemnifying Party's
         indemnification obligation with respect to such Third Party Claim shall
         not exceed the amount that would be required to be paid by or on behalf
         of the Indemnifying Party in connection with such settlement,
         compromise or discharge. If an Indemnifying Party elects not to assume
         the defense of a Third Party Claim, or fails to notify an Indemnitee of
         its election to do so as provided herein, such Indemnitee may
         compromise, settle or defend such Third Party Claim.

               (iv)   Notwithstanding the foregoing, the Indemnifying Party
         shall not be entitled to assume the defense of any Third Party Claim
         (and shall be liable for the fees and expenses of counsel incurred by
         the Indemnitee in defending such Third Party Claim) if the Third Party
         Claim seeks an order, injunction or other equitable relief or relief
         for other than money damages against the Indemnitee which the
         Indemnitee reasonably determines, after conferring with its counsel,
         cannot be separated from any related claim for money damages. If such
         equitable relief or other relief portion of the Third Party Claim can
         be so separated from that for money damages, the Indemnifying Party
         shall be entitled to assume the defense of the portion relating to
         money damages (provided, that the Indemnifying Party shall indemnify
         the Indemnified Party for the fees and expenses of counsel incurred by
         the Indemnified Party in defending such portion of the claim seeking
         relief for other than money damages).

         (b)   SUBROGATION. In the event of payment by an Indemnifying Party
to any Indemnitee in connection with any Third-Party Claim, such Indemnifying
Party shall be subrogated to and shall stand in the place of such Indemnitee as
to any events or circumstances in respect of which such Indemnitee may have any
right or claim relating to such Third-Party Claim against any claimant or
plaintiff asserting such Third-Party Claim. Such Indemnitee shall

                                       40

<PAGE>

cooperate with such Indemnifying Party in a reasonable manner, and at the cost
and expense of such Indemnifying Party, in prosecuting any subrogated right or
claim.

         (c)   OTHER CLAIMS. In the event that an Indemnitee asserts the
existence of a claim giving rise to Indemnifiable Losses (but excluding claims
resulting from the assertion of liability by third parties), it shall give
notice to the Indemnifying Party specifying the nature and amount of the claim
asserted. In the event that the Indemnifying Party contests the assertion of a
claim by giving notice to the Indemnitee, then if the parties hereto, acting in
good faith, cannot reach agreement with respect to such claim within ten days
after such response notice, the Indemnitee is entitled to seek any available
legal remedy in a manner consistent with the dispute resolution mechanism set
forth in Article VII.

         (d)   CONTRIBUTION. If the indemnification provided for in this Article
III is unavailable to an Indemnitee with respect to an Indemnifiable Loss
arising out of or related to information contained in the Information Statement
or Form 10, then the Indemnifying Party, in lieu of indemnifying such
Indemnitee, shall contribute to the amount paid or payable by such Indemnitee as
a result of such Indemnifiable Loss, in such proportion as is appropriate to
reflect the relative fault of the IMPCO Group, on the one hand, and Quantum, on
the other hand. The relative fault of any party shall be determined by reference
to, among other things, whether the untrue or alleged untrue statement of a
material fact or the omission or alleged omission to state a material fact
relates to information supplied by that party or one of its Affiliates.

         (e)   NON-EXCLUSIVE REMEDY. The remedies provided in this Article III
shall be cumulative and shall not preclude assertion by any Indemnitee of any
other rights or the seeking of any and all other remedies against any
Indemnifying Party.

         (f)   REMEDY LIMITATION. All disputes, controversies or claims arising
out of or relating to this Agreement or the breach, termination or validity
thereof (a "Dispute") brought by a third party beneficiary to this Agreement
shall be exclusively and finally settled in accordance with the dispute
resolution mechanism set forth in Article VII. In the event of a Dispute
regarding the availability of third party benefits, no third party benefits
provided by this Agreement shall be available to any third party beneficiary who
pursues any form of dispute resolution inconsistent with the dispute resolution
mechanism set forth in Article VII.

         SECTION 3.4  INDEMNIFICATION PAYMENTS. Indemnification required by this
Article III shall be made by periodic payments of the amount thereof during the
course of the investigation or defense, as and when bills are received or loss,
liability, claim, damage or expense is incurred.

                                       41

         SECTION 3.5  FUTURE BUSINESS RELATIONSHIPS. The parties hereto
acknowledge that after the Distribution Date the parties may enter into
arms-length negotiated business relationships, which relationships will be
described in contracts, agreements and other documents entered into in the
normal course of business. Such documents may include agreements by the parties
and their Affiliates and Subsidiaries to supply materials, products, services
and leases after the Distribution Date. Except for the arrangements under the
Ancillary Agreements, such additional business relationships shall not be
subject to the indemnity provisions hereof, unless the parties expressly agree
to the contrary in the agreements governing such relationships.

                                   ARTICLE IV

                              ACCESS TO INFORMATION

         SECTION 4.1  PROVISION OF CORPORATE RECORDS.

         (a)   Other than in circumstances in which indemnification is sought
pursuant to Article III (in which event the provisions of such Article will
govern) and subject to Section 4.4, each of IMPCO and Quantum, on behalf of its
respective Group, agrees to provide, or cause to be provided, to each other
Group, as soon as reasonably practicable after written request therefor,
specific and identified agreements, documents, books, records or files
(collectively, "Records") in the possession or under the control of such
respective Group which the requesting party reasonably needs (i) to comply with
reporting, disclosure, filing or other requirements imposed on the requesting
party (including under applicable securities or tax laws) by a Governmental
Authority having jurisdiction over the requesting party, (ii) for use in any
other judicial, regulatory, administrative, tax or other proceeding or in order
to satisfy audit, accounting, claims, regulatory, litigation, tax or other
similar requirements, in each case other than claims or allegations that one
party to this Agreement has against the other, or (iii) subject to clause (ii)
above, to comply with its obligations under this Agreement or any Ancillary
Agreement; provided, however, that in the event that any party reasonably
determines that any such provision of Records could be commercially detrimental,
violate any law or agreement, or waive any attorney-client privilege, the
parties shall take all reasonable measures to permit the compliance with such
obligations in a manner that avoids any such harm or consequence.

         (b)   From and after the Contribution Date, each of IMPCO and Quantum
shall maintain in effect at its own cost and expense adequate systems and
controls to the extent necessary to enable the members of the other Group to
satisfy their respective reporting, accounting, audit and other obligations.

         SECTION 4.2  ACCESS TO INFORMATION.

         (a)   Other than in circumstances in which indemnification is sought
pursuant to Article III (in which event the provisions of such Article will
govern) and subject to Section 4.4, from and after the Distribution Date, each
of IMPCO and Quantum shall afford to the other and its authorized accountants,
counsel and other designated representatives reasonable access during normal
business hours, subject to appropriate restrictions for classified, privileged
or confidential

                                       42

<PAGE>

information, to the personnel, properties, books and records of such party and
its Subsidiaries insofar as such access is reasonably required by the other
party and relates to (x) such other party or the conduct of its business prior
to the Effective Time or (y) any Ancillary Agreement to which each of the party
requesting such access and the party requested to grant such access are parties.

         (b)   Other than in circumstances in which indemnification is sought
pursuant to Article III (in which event the provisions of such Article will
govern) and subject to Section 4.4, from and after the Contribution Date,
Quantum shall have access during regular business hours (as in effect from time
to time) to the documents and objects of historic significance that relate to
the Quantum Business that are located in archives retained or maintained by
IMPCO. Quantum may obtain copies (but not originals) of such documents for bona
fide business purposes. Nothing herein shall be deemed to restrict the access of
any member of the IMPCO Group to any such documents or to impose any liability
on any member of the IMPCO Group if any such documents are not maintained or
preserved by IMPCO; provided, however, that in the event that any party
reasonably determines that any such provision of access could be commercially
detrimental, violate any law or agreement, or waive any attorney-client
privilege, the parties shall take all reasonable measures to permit the
compliance with such obligations in a manner that avoids any such harm or
consequence.

         SECTION 4.3  REIMBURSEMENT; OTHER MATTERS. Except to the extent
otherwise contemplated by any Ancillary Agreement, a party providing Records or
access to information to the other party under this Article IV shall be entitled
to receive from the recipient, upon the presentation of invoices therefor,
payments for such amounts, relating to supplies, disbursements and other
out-of-pocket expenses, as may be reasonably incurred in providing such Records
or access to information.

         SECTION 4.4  CONFIDENTIALITY.

         (a)   Each of (i) IMPCO and its Subsidiaries, on the one hand, and (ii)
Quantum and its Subsidiaries, on the other, shall not use, or permit the use of,
or disclose, and shall keep, and shall cause its employees, consultants and
advisors to keep confidential, the Confidential Information of the other parties
except: (a) the Recipient may use the Discloser's Confidential Information in
order to reasonably carry out its obligations and exercise its rights under this
Agreement and the Ancillary Agreements; (b) Recipient may disclose the
Confidential Information of the Discloser to its employees and independent
contractors who have a need to know such Confidential Information and who are
bound by confidentiality obligations similar to those contained in this
Agreement; (c) as permitted under this Agreement or any Ancillary Agreement; and
(d) in order to enforce this Agreement or any Ancillary Agreement. Recipient
will take precautions to prevent unauthorized disclosure or use of the
Confidential Information of the Discloser, and such precautions will be
consistent with the precautions used to protect the Recipient's own Confidential
Information, but in no event less than the care exercised by a reasonable
business person in the protection of its valuable confidential information. In
the event that Recipient is compelled to disclose the Confidential Information
of Discloser pursuant to judicial or administrative process or by law or
applicable securities rules or regulations, the Recipient will give the
Discloser reasonable advance notice of any such disclosure and will

                                       43

<PAGE>

cooperate with the Discloser in protecting against any such disclosure and/or
obtaining a protective order narrowing the scope of such disclosure and/or use
of such Confidential Information. The Recipient will not make any copies of the
Discloser's Confidential Information except to the extent reasonably necessary
to carry out its obligations and exercise its rights under this Agreement and
the Ancillary Agreements, or unless otherwise approved in writing in advance by
the Discloser. The Recipient will use commercially reasonable efforts to ensure
that all such copies made after the Effective Time will be identified as the
property of the Discloser and marked "confidential," "proprietary" or with
another similar legend.

         (b)   Without limiting the generality of the foregoing, (a) IMPCO
shall, upon the request of Quantum and at Quantum's sole expense (including
disbursements and costs of salaries, plus a fixed rate in the amount of thirty
percent (30%), and other out-of-pocket expenses incurred by IMPCO in connection
therewith), during the three (3) year period beginning on the Contribution Date,
promptly enforce the breach by any of its present or former employees of any
agreement between IMPCO and such employee prohibiting such employee from using
or disclosing any Confidential Information owned by Quantum, and (b) Quantum
shall, upon the request of IMPCO and at IMPCO's sole expense (including
disbursements and costs of salaries, plus a fixed rate in the amount of thirty
percent (30%), and other out-of-pocket expenses incurred by Quantum in
connection therewith), during the three (3) year period beginning on the
Contribution Date, promptly enforce the breach by any of its present or former
employees of any agreement between Quantum and such employee prohibiting such
employee from using or disclosing any Confidential Information owned by IMPCO.

         SECTION 4.5  PRIVILEGED MATTERS. The parties hereto recognize that
legal and other professional services that have been and will be provided prior
to the Distribution Date have been and will be rendered for the benefit of each
of IMPCO, the members of the IMPCO Group and the members of the Quantum Group,
and that each of IMPCO, the members of the IMPCO Group and the members of the
Quantum Group should be deemed to be the client for the purposes of asserting
all privileges which may be asserted under applicable law. To allocate the
interests of each party in the information as to which any party is entitled to
assert a privilege, the parties agree as follows:

         (a)   IMPCO shall be entitled, in perpetuity, to control the assertion
or waiver of all privileges in connection with privileged information which
relates solely to the IMPCO Business, whether or not the privileged information
is in the possession of or under the control of IMPCO or Quantum. IMPCO shall
also be entitled, in perpetuity, to control the assertion or waiver of all
privileges in connection with privileged information that relates solely to the
subject matter of any claims constituting IMPCO Liabilities, now pending or
which may be asserted in the future, in any lawsuits or other proceedings
initiated against or by IMPCO, whether or not the privileged information is in
the possession of or under the control of IMPCO or Quantum.

         (b)   Quantum shall be entitled, in perpetuity, to control the
assertion or waiver of all privileges in connection with privileged information
which relates solely to the Quantum Business, whether or not the privileged
information is in the possession of or under the control of IMPCO or Quantum.
Quantum shall also be entitled, in perpetuity, to control the assertion or

                                       44

<PAGE>

waiver of all privileges in connection with privileged information which relates
solely to the subject matter of any claims constituting Quantum Liabilities, now
pending or which may be asserted in the future, in any lawsuits or other
proceedings initiated against or by Quantum whether or not the privileged
information is in the possession of or under the control of IMPCO or Quantum.

         (c)   The parties hereto agree that they shall have a shared privilege,
with equal right to assert or waive, subject to the restrictions in this Section
4.5, with respect to all privileges not allocated pursuant to the terms of
Sections 4.5(a) and (b). All privileges relating to any claims, proceedings,
litigation, disputes, or other matters which involve both IMPCO and Quantum in
respect of which both parties retain any responsibility or liability under this
Agreement, shall be subject to a shared privilege among them.

         (d)   No party hereto may waive any privilege which could be asserted
under any applicable law, and in which any other party hereto has a shared
privilege, without the consent of the other party, except to the extent
reasonably required in connection with any litigation with third-parties (and
then only to the limited extent necessary under the circumstances) or as
provided in subsection (e) below. Consent shall be in writing, or shall be
deemed to be granted unless written objection is made within twenty (20) days
after written notice upon the other party requesting such consent.

         (e)   In the event of any litigation or dispute between or among any of
the parties hereto, any party and a Subsidiary of another party hereto, or a
Subsidiary of one party hereto and a Subsidiary of another party hereto, either
such party may waive a privilege in which the other party has a shared
privilege, without obtaining the consent of the other party, provided that such
waiver of a shared privilege shall be effective only as to the use of
information with respect to the litigation or dispute between the parties and/or
their Subsidiaries, and shall not operate as a waiver of the shared privilege
with respect to third parties.

         (f)   If a dispute arises between or among the parties hereto or their
respective Subsidiaries regarding whether a privilege should be waived to
protect or advance the interest of any party, each party agrees that it shall
negotiate in good faith, shall endeavor to minimize any prejudice to the rights
of the other parties, and shall not unreasonably withhold consent to any request
for waiver by another party. Each party hereto specifically agrees that it will
not withhold consent to waiver for any purpose except to protect its own
legitimate interests.

         (g)   Upon receipt by any party hereto or by any Subsidiary thereof of
any subpoena, discovery or other request which arguably calls for the production
or disclosure of information subject to a shared privilege or as to which
another party has the sole right hereunder to assert a privilege, or if any
party obtains knowledge that any of its or any of its Subsidiaries' current or
former directors, officers, agents or employees have received any subpoena,
discovery or other requests which arguably calls for the production or
disclosure of such privileged information, such party shall promptly notify the
other party or parties of the existence of the request and shall provide the
other party or parties a reasonable opportunity to review the information and to
assert any rights it or they may have under this Section 4.5 or otherwise to
prevent the production or disclosure of such privileged information.

                                       45

<PAGE>

      (h) The transfer of all Records and other information pursuant to this
Agreement is made in reliance on the agreement of IMPCO and Quantum, as set
forth in Sections 4.4 and 4.5, to maintain the confidentiality of privileged
information and to assert and maintain all applicable privileges. The access to
information being granted pursuant to Sections 4.1 and 4.2 hereof, the agreement
to provide witnesses and individuals pursuant to Sections 2.10 and 3.3 hereof,
the furnishing of notices and documents and other cooperative efforts
contemplated by Section 3.3 hereof, and the transfer of privileged information
between and among the parties and their respective Subsidiaries pursuant to this
Agreement shall not be deemed a waiver of any privilege that has been or may be
asserted under this Agreement or otherwise.

      SECTION 4.6 OWNERSHIP OF INFORMATION. Any information owned by one party
or any of its Subsidiaries that is provided to a requesting party pursuant to
Article III or this Article IV shall be deemed to remain the property of the
providing party. Unless specifically set forth herein, nothing contained in this
Agreement shall be construed as granting or conferring rights of license or
otherwise in any such information.

      SECTION 4.7 ESTIMATES. No party shall have any liability to any other
party in the event that any information exchanged or provided pursuant to this
Agreement which is an estimate or forecast, or which is based on an estimate or
forecast, is found to be inaccurate.

      SECTION 4.8 OTHER AGREEMENTS PROVIDING FOR EXCHANGE OF INFORMATION. The
rights and obligations granted under this Article IV are subject to any specific
limitations, qualifications or additional provisions on the sharing, exchange or
confidential treatment of information set forth in any Ancillary Agreement.

                                   ARTICLE V

                    TERMINATION OF AGREEMENTS; MUTUAL RELEASE

      SECTION 5.1 TERMINATION OF AGREEMENTS.

      (a) IMPCO and each of its wholly-owned Subsidiaries, on the one hand, and
Quantum and each of its wholly-owned Subsidiaries, on the other hand, hereby
terminate any and all agreements, arrangements, commitments or understandings,
whether or not in writing, between or among, IMPCO and/or any of its
wholly-owned Subsidiaries, on the one hand, and Quantum and/or any of its
wholly-owned Subsidiaries, on the other hand, effective as of the Distribution
Date. No such terminated agreement, arrangement, commitment or understanding
(including any provision thereof which purports to survive termination) shall be
of any further force or effect after the Distribution Date. Each party shall, at
the reasonable request of any other party, take, or cause to be taken, such
other actions as may be necessary to effect the foregoing.

      (b) The provisions of Section 5.1(a) shall not apply to any of the
following agreements, arrangements, commitments or understandings (or to any of
the provisions thereof): (i) this Agreement and the Ancillary Agreements (and
each other agreement or instrument

                                       46

<PAGE>

expressly contemplated hereby or thereby to be entered into by any of the
parties hereto or any of their wholly-owned Subsidiaries); (ii) any agreements,
arrangements, commitments or understandings listed or described on Schedule
5.1(b); (iii) the Intercompany Accounts referenced in Section 2.3; and (iv) any
other agreements, arrangements, commitments or understandings that this
Agreement, any Ancillary Agreement or any agreements entered into connection
herewith or therewith, expressly contemplates will survive the Distribution
Date.

      SECTION 5.2 MUTUAL RELEASE.

      (a) Except as provided in Section 5.2(c), effective as of the Distribution
Date, Quantum does hereby, for itself and each member of the Quantum Group,
their respective successors and assigns, remise, release and forever discharge
IMPCO, each of member of the IMPCO Group, and their respective successors and
assigns, from any and all liabilities whatsoever, whether at law or in equity
(including any right of contribution), whether arising under any contract or
agreement, by operation of law or otherwise, existing or arising from any acts
or events occurring or failing to occur or alleged to have occurred or to have
failed to occur or any conditions existing or alleged to have existed on or
before the Distribution Date, including in connection with the transactions and
all other activities to implement the Contribution and the Distribution.

      (b) Except as provided in Section 5.2(c), effective as of the Distribution
Date, IMPCO does hereby, for itself and each member of the IMPCO Group, their
respective successors and assigns, remise, release and forever discharge
Quantum, each other member of the Quantum Group, and their respective successors
and assigns from any and all liabilities whatsoever, whether at law or in equity
(including any right of contribution), whether arising under any contract or
agreement, by operation of law or otherwise, existing or arising from any acts
or events occurring or failing to occur or alleged to have occurred or to have
failed to occur or any conditions existing or alleged to have existed on or
before the Distribution Date, including in connection with the transactions and
all other activities to implement the Contribution and the Distribution.

      (c) Nothing contained in Sections 5.2(a) or (b) shall impair any right of
any person to enforce this Agreement, any Ancillary Agreement or any agreements,
arrangements, commitments or understandings that are specified in Section 5.1(b)
or the applicable Schedules thereto, in each case in accordance with its terms.
Nothing contained in Sections 5.2(a) or (b) shall release any person from: (i)
any liability provided in or resulting from any agreements, arrangements,
commitments or understandings among IMPCO or any of its wholly-owned
Subsidiaries and Quantum and any of its wholly-owned Subsidiaries that is
specified in Section 5.1(b) or the applicable Schedules thereto, (ii) any other
liability specified in such Section 5.1(b), (iii) any other liability which by
the terms of this Agreement, any Ancillary Agreement, the Contribution Agreement
or any other agreement entered into in connection herewith or therewith should
survive the Distribution Date; and (iv) any liability that the parties may have
with respect to indemnification or contribution pursuant to this Agreement for
claims brought against the parties by third persons, which liability shall be
governed by the provisions of Article III of this Agreement and, if applicable,
the appropriate provisions of the Ancillary Agreements. In addition, nothing
contained in Sections 5.2(a) or (b) shall release IMPCO from honoring its

                                       47

<PAGE>

existing obligations to indemnify any director, officer or employee of Quantum
who was a director, officer or employee of IMPCO on or prior to the Distribution
Date, to the extent such director, officer or employee was entitled to such
indemnification pursuant to any then-existing obligation of IMPCO.

      (d) Quantum shall not make, and shall not permit any member of the Quantum
Group to make, any claim or demand, or commence any Action asserting any claim
or demand, including any claim of contribution or any indemnification, against
IMPCO or any member of the IMPCO Group with respect to any liabilities released
pursuant to Section 5.2(a). IMPCO shall not, and shall not permit any member of
the IMPCO Group, to make any claim or demand, or commence any Action asserting
any claim or demand, including any claim of contribution or any indemnification,
against Quantum or any member of the Quantum Group with respect to any
liabilities released pursuant to Section 5.2(b).

      (e) It is the intent of IMPCO and Quantum by virtue of the provisions of
this Section 5.2 to provide for a full and complete release and discharge of all
liabilities existing or arising from all acts and events occurring or failing to
occur or alleged to have occurred or to have failed to occur and all conditions
existing or alleged to have existed on or before the Distribution Date, between
or among Quantum or any member of the Quantum Group, on the one hand, and IMPCO
or any member of the IMPCO Group, on the other hand (including any contractual
agreements or arrangements existing or alleged to exist between or among any
such members on or before the Distribution Date), except as expressly set forth
in Section 5.2(c). At any time, at the request of any other party, each party
shall cause each member of its respective Group to execute and deliver releases
reflecting the provisions hereof.

      (f) The parties understand and agree that the release herein includes not
only claims presently known to them, but also includes all unknown or
unanticipated claims, rights, demands, actions, obligations, liabilities, and
causes of action of every kind and character that would otherwise come within
the scope of the release as described in this Section 5.2. Each of the parties
understand that they may hereafter discover facts different from what they now
believe to be true, which if known, could have materially affected this
Agreement and the transactions contemplated hereby, but they nevertheless waive
any claims or rights based on different or additional facts. The parties
knowingly and voluntarily waive any and all rights or benefits that they may now
have, or in the future may have, under the terms of Section 1542 of the
California Civil Code, which provides as follows:

      A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS WHICH THE CREDITOR DOES NOT
      KNOW OR SUSPECT TO EXIST IN HIS FAVOR AT THE TIME OF EXECUTING THE
      RELEASE, WHICH IF KNOWN BY HIM MUST HAVE MATERIALLY AFFECTED HIS
      SETTLEMENT WITH THE DEBTOR.

                                   ARTICLE VI

                             ADMINISTRATIVE SERVICES

      SECTION 6.1 PERFORMANCE OF SERVICES. IMPCO will provide, or cause one or
more of its Subsidiaries to provide, to Quantum and its Subsidiaries such
services on such terms and for such periods of time as may be set forth in the
Transition Services Agreement and the statements of work entered into
thereunder.

      SECTION 6.2 ACCOUNTS RECEIVABLE. IMPCO agrees to cooperate with Quantum,
at Quantum's expense, in the collection of any accounts receivable transferred
by IMPCO to Quantum pursuant to the terms of this Agreement (the "Receivables").
IMPCO acknowledges that it may, from time to time, receive payments in respect
of the Receivables. In the event that IMPCO receives any payments with respect
to the Receivables, IMPCO shall promptly upon receipt thereof remit such
payments to Quantum. Quantum shall reimburse IMPCO for all reasonable costs and
expenses incurred by IMPCO in complying with the provisions of this Section 6.2.

                                  ARTICLE VII

                               DISPUTE RESOLUTION

      SECTION 7.1 NEGOTIATION. In the event of a controversy, dispute or claim
arising out of, in connection with, or in relation to the interpretation,
performance, nonperformance, validity or breach of this Agreement, any Ancillary
Agreement or otherwise arising out of, or in any way related to this Agreement
or any Ancillary Agreement or the transactions contemplated hereby or thereby,
including, without limitation, any claim based on contract, tort, statute or
constitution (but excluding any controversy, dispute or claim arising out of any
agreement relating to the use or lease of real property if any third party is a
party to such controversy, dispute or claim) (collectively, "Agreement
Disputes"), the parties shall first negotiate to settle such Agreement Dispute
for a period of time not to exceed 30 days from the time of receipt by a party
of written notice of an Agreement Dispute ("Notice"), unless otherwise agreed by
the parties in writing; provided that in the event of any arbitration in
accordance with Section 6.2 hereof filed within 90 days of receipt of Notice,
the parties shall not assert the defenses of statute of limitations or laches
arising for the period beginning after the date the parties began negotiations
hereunder, and any contractual time period or deadline under this Agreement or
any Ancillary Agreement to which such Agreement Dispute relates shall not be
deemed to have passed until such Agreement Dispute has been resolved.

      SECTION 7.2 ARBITRATION. After 30 days have elapsed from the time of
receipt of Notice of an Agreement Dispute, such Agreement Dispute shall be
determined, at the request of any party, by arbitration conducted in Los
Angeles, California before and in accordance with the then-existing Commercial
Arbitration Rules of the American Arbitration Association (the "Rules"). In any
dispute between the parties hereto, the number of arbitrators shall be three.
Any judgment or award rendered by the arbitrators shall be final, binding and
nonappealable (except upon grounds specified in 9 U.S.C. ss. 10(a) as in effect
on the date hereof). If the parties

                                       49

<PAGE>

are unable to agree on the arbitrators within 30 days of receipt by the
respondent of the demand, the arbitrators shall be selected in accordance with
the Rules; provided that the arbitrators shall be U.S. nationals. Any
controversy concerning whether an Agreement Dispute is an arbitrable Agreement
Dispute, whether arbitration has been waived, whether an assignee of this
Agreement is bound to arbitrate, or as to the interpretation or enforceability
of this Article VII shall be determined by the arbitrators. In resolving any
dispute, the parties intend that the arbitrators apply the substantive laws of
the State of California, without regard to the choice of law principles thereof.
The parties intend that the provisions to arbitrate set forth herein be valid,
enforceable and irrevocable. The parties agree to comply with any award made in
any such arbitration proceeding that has become final in accordance with the
Rules and agree to enforcement of or entry of judgment upon such award, by any
court of competent jurisdiction, including (a) the Superior Court of the State
of California, Los Angeles County, or (b) the United States District Court for
the Central District of California, in accordance with Section 9.17 hereof. The
arbitrators shall be entitled, if appropriate, to award any remedy in such
proceedings, including, without limitation, monetary damages, specific
performance and all other forms of legal and equitable relief; provided,
however, the arbitrators shall not be entitled to award punitive damages.
Without limiting the provisions of the Rules, unless otherwise agreed in writing
by or among the parties or permitted by this Agreement, the parties shall keep
confidential all matters relating to the arbitration or the award, provided such
matters may be disclosed (i) to the extent reasonably necessary in any
proceeding brought to enforce the award or for entry of a judgment upon the
award and (ii) to the extent otherwise required by law. Notwithstanding Section
52 of the Rules, the party other than the prevailing party in the arbitration
shall be responsible for all of the costs of the arbitration, including legal
fees and other costs specified by such Section 52. Nothing contained herein is
intended to or shall be construed to prevent any party, in accordance with
Section 36 of the Rules or otherwise, from applying to any court of competent
jurisdiction for interim measures or other provisional relief in connection with
the subject matter of any Agreement Disputes.

      SECTION 7.3 CONTINUITY OF SERVICE AND PERFORMANCE. Unless otherwise agreed
in writing, the parties will continue to provide service and honor all other
commitments under this Agreement and each Ancillary Agreement during the course
of dispute resolution pursuant to the provisions of this Article VII with
respect to all matters not subject to such dispute, controversy or claim.

                                  ARTICLE VIII

                                    INSURANCE

      SECTION 8.1 POLICIES AND RIGHTS INCLUDED WITHIN ASSETS; ASSIGNMENT OF
POLICIES.

      (a) POLICY RIGHTS. The Quantum Assets shall include (i) any and all rights
of an insured party under each of the Shared Policies, subject to the terms of
such Shared Policies and any limitations or obligations of Quantum contemplated
by this Article VIII, specifically including rights of indemnity and the right
to be defended by or at the expense of the insurer, with respect to all claims,
suits, actions, proceedings, injuries, losses, liabilities, damages and expenses
incurred or claimed to have been incurred prior to the Effective Time by any
party in or

                                       50

<PAGE>

in connection with the conduct of the Quantum Business or, to the extent any
claim is made against Quantum or any of its Subsidiaries, the conduct of the
IMPCO Business, and which claims, suits, actions, proceedings, injuries, losses,
liabilities, damages and expenses may arise out of an insured or insurable
occurrence under one or more of such Shared Policies.

         (b) ASSIGNMENT OF SHARED POLICIES. Subject to the terms and conditions
hereof, Quantum hereby assigns, transfers and conveys to IMPCO all of Quantum's
right, title and interest in and to any and all of the Shared Policies,
including, without limitation, the right of indemnity, the right to be defended
by or at the expense of the insurer and the right to any applicable Insurance
Proceeds thereunder; and IMPCO and Quantum shall use their commercially
reasonable efforts to obtain any required consents of insurers to the assignment
contemplated by this paragraph.

         (c) DESIGNATION AS ATTORNEY-IN-FACT. If, subsequent to the Distribution
Date, any person shall assert a claim against Quantum or any of its Subsidiaries
(including, without limitation, where Quantum or its Subsidiaries are joint
defendants with other persons) with respect to any claim, suit, action,
proceeding, injury, loss, liability, damage or expense incurred or claimed to
have been incurred prior to the Distribution Date in or in connection with the
conduct of the Quantum Business or, to the extent any claim is made against
Quantum or any of its Subsidiaries (including, without limitation, where Quantum
or its Subsidiaries are joint defendants with other persons), in connection with
the conduct of the IMPCO Business, and which claim, suit, action, proceeding,
injury, loss, liability, damage or expense may arise out of an insured or
insurable occurrence under one or more of the Shared Policies, IMPCO shall, at
the time such claim is asserted, to the extent any such Policy may require that
Insurance Proceeds thereunder be collected directly by the named insured or
anyone other than the party against whom the Insured Claim is asserted, be
deemed to designate, without need of further documentation, Quantum as the agent
and attorney-in-fact to assert and to collect any related Insurance Proceeds
under such Shared Policy.

         SECTION 8.2 ADMINISTRATION; OTHER MATTERS.

         (a) ADMINISTRATION. From and after the Distribution Date, IMPCO shall
be responsible for (i) Insurance Administration of the Shared Policies and (ii)
Claims Administration under such Shared Policies with respect to Insured Claims
of IMPCO and Insured Claims of Quantum; provided that the assumption of such
responsibilities by IMPCO is in no way intended to limit, inhibit or preclude
any right to insurance coverage for any Insured Claim of a named insured under
such Policies as contemplated by the terms of this Agreement; provided further
that IMPCO's assumption of the administrative responsibilities for the Shared
Policies shall not relieve the party submitting any Insured Claim of the primary
responsibility for reporting such Insured Claim accurately, completely and in a
timely manner or of such party's authority to settle any such Insured Claim
within any period permitted or required by the relevant Policy; and provided
further that all direct or indirect communication with insurers relating to the
Shared Policies shall be conducted by IMPCO. IMPCO may discharge its
administrative responsibilities under this Section 8.2 by contracting for the
provision of services by independent parties. Each of the parties hereto shall
administer and pay any costs relating to defending its respective Insured Claims
under Shared Policies to the extent such defense costs are not covered under
such Policies and shall be responsible for obtaining or reviewing the
appropriateness of

                                       51

<PAGE>

releases upon settlement of its respective Insured Claims under Shared Policies.
The disbursements, out-of-pocket expenses and direct and indirect costs of
employees or agents of IMPCO relating to Claims Administration and Insurance
Administration contemplated by this Section 8.2(a) shall be for Quantum's
account if they relate to Insured Claims of Quantum and for IMPCO's account if
they relate to Insured Claims of IMPCO.

         (b) EXCEEDING POLICY LIMITS. Except as set forth in this Section
8.2(b), IMPCO and Quantum shall not be liable to one another for claims not
reimbursed by insurers for any reason not within the control of IMPCO or
Quantum, as the case may be, including, without limitation, coinsurance
provisions, deductibles, quota share deductibles, self-insured retentions,
bankruptcy or insolvency of an insurance carrier, Shared Policy limitations or
restrictions, any coverage disputes, any failure to timely claim by IMPCO or
Quantum or any defect in such claim or its processing, provided that Quantum
shall be responsible for the amount of the difference, if any, between the
deductible set forth in any Shared Policy and the deductible allocable to IMPCO
as set forth in Schedule 8.2(b) hereto.

         (c) ALLOCATION OF INSURANCE PROCEEDS. Insurance Proceeds received with
respect to claims, costs and expenses under the Shared Policies shall be paid to
IMPCO, which shall thereafter administer the Shared Policies by paying the
Insurance Proceeds, as appropriate, to Quantum with respect to Insured Claims of
Quantum and to IMPCO with respect to Insured Claims of IMPCO. Payment of the
allocable portions of indemnity costs of Insurance Proceeds resulting from such
Policies will be made by IMPCO to the appropriate party upon receipt from the
insurance carrier. In the event that the aggregate limits on any Shared Policies
are exceeded by the aggregate of outstanding Insured Claims by both of the
parties hereto, the parties agree to allocate the Insurance Proceeds received
thereunder based upon their respective percentage of the total of their bona
fide claims which were covered under such Shared Policy (their "allocable
portion of Insurance Proceeds"), and any party who has received Insurance
Proceeds in excess of such party's allocable portion of Insurance Proceeds shall
pay to the other party the appropriate amount so that each party will have
received its allocable portion of Insurance Proceeds pursuant hereto. Each of
the parties agrees to use commercially reasonable efforts to maximize available
coverage under those Shared Policies applicable to it, and to take all
commercially reasonable steps to recover from all other responsible parties in
respect of an Insured Claim to the extent coverage limits under a Shared Policy
have been exceeded or would be exceeded as a result of such Insured Claim.

         (d) ALLOCATION OF DEDUCTIBLES. In the event that both parties have bona
fide claims under any Shared Policy for which a deductible is payable, the
parties agree that the aggregate amount of the deductible paid shall be borne by
the parties in the same proportion which the Insurance Proceeds received by each
such party bears to the total Insurance Proceeds received under the applicable
Shared Policy (their "allocable share of the deductible"), and any party who has
paid more than such share of the deductible shall be entitled to receive from
the other party an appropriate amount so that each party has borne its allocable
share of the deductible pursuant hereto. For purposes of this Section 8.2(d),
the amount of the relevant deductible under any Shared Policy shall be that set
forth in Schedule 8.2(d) hereto.

                                       52

<PAGE>

         (e) Effective as of the Distribution Date, each of Quantum and IMPCO
shall be responsible for its applicable deductible for workers' compensation,
general liability and automobile liability claims as set forth in Schedule
8.2(e).

         SECTION 8.3 AGREEMENT FOR WAIVER OF CONFLICT AND SHARED DEFENSE. In the
event that Insured Claims of both of the parties hereto exist relating to the
same occurrence, the parties shall jointly defend and waive any conflict of
interest necessary to the conduct of the joint defense. Nothing in this Article
VIII shall be construed to limit or otherwise alter in any way the obligations
of the parties to this Agreement, including those created by this Agreement, by
operation of law or otherwise.

         SECTION 8.4 COOPERATION. The parties agree to use their commercially
reasonable efforts to cooperate with respect to the various insurance matters
contemplated by this Agreement.

                                   ARTICLE IX

                                  MISCELLANEOUS

         SECTION 9.1 COMPLETE AGREEMENT; CONSTRUCTION. This Agreement, including
the Exhibits and Schedules, and the Ancillary Agreements shall constitute the
entire agreement between the parties with respect to the subject matter hereof
and shall supersede all previous negotiations, commitments and writings with
respect to such subject matter. In the event of any inconsistency between this
Agreement and any Schedule hereto, the Schedule shall prevail. Other than
Section 2.8, Section 4.5, and Article VII of this Agreement, which shall prevail
over any inconsistent or conflicting provisions of any Ancillary Agreement,
notwithstanding any other provisions in this Agreements to the contrary, in the
event of and to the extent that there shall be a conflict between the provisions
of this Agreement and the provisions of any Ancillary Agreement, such Ancillary
Agreement shall control.

         SECTION 9.2 ANCILLARY AGREEMENTS. Subject to the last sentence of
Section 9.1, this Agreement is not intended to address, and should not be
interpreted to address, the matters specifically and expressly covered by the
Ancillary Agreements.

         SECTION 9.3 COUNTERPARTS. This Agreement may be executed in one or more
counterparts, all of which shall be considered one and the same agreement, and
shall become effective when one or more such counterparts have been signed by
each of the parties and delivered to the other parties.

         SECTION 9.4 SURVIVAL OF AGREEMENTS. Except as otherwise contemplated by
this Agreement, all covenants and agreements of the parties contained in this
Agreement shall survive the Distribution Date.

otherwise set forth in this Agreement or any Ancillary Agreement, all costs and
expenses incurred in connection with the preparation, execution, delivery and
required implementation of this Agreement and any Ancillary Agreement, the
Information Statement (including any registration statement on Form 10 of which
such Information Statement may be a part) and the Distribution, and the
consummation of the transactions contemplated thereby, and not paid prior to the
Distribution Date, shall be charged to and paid by Quantum. Except as set forth
on Schedule 9.5(ii) or as otherwise set forth in this Agreement or any Ancillary
Agreement, each party shall bear its own costs and expenses incurred after the
Distribution Date. Any amount or expense to be paid or reimbursed by any party
hereto to any other party hereto shall be so paid or reimbursed promptly after
the existence and amount of such obligation is determined and demand therefor is
made.

         SECTION 9.6 NOTICES. All notices and other communications hereunder
shall be in writing and hand delivered or mailed by registered or certified mail
(return receipt requested) to the parties at the following addresses (or at such
other addresses for a party as shall be specified by like notice) and will be

         SECTION 9.7 WAIVERS. The failure of any party to require strict

the sole discretion of IMPCO without the approval of Quantum or the shareholders
of IMPCO. In the event of such termination, no party shall have any liability of
any kind to any other party or any other person. After the Distribution, this
Agreement may not be terminated except by an agreement in writing signed by the
parties; provided, however, that Article III shall not be terminated or amended
after the Distribution in respect of the third party beneficiaries thereto
without the consent of such persons.

         SECTION 9.12 SUBSIDIARIES. Each of the parties hereto shall cause to be

of Article VII hereof, each of the parties irrevocably submits to the exclusive
jurisdiction of (a) the Superior Court of the State of California, Los Angeles
County, and (b) the United States District Court for the Central District of

         SECTION 9.18 SEVERABILITY. In the event any one or more of the
provisions contained in this Agreement should be held invalid, illegal or
unenforceable in any respect, the validity, legality and enforceability of the
remaining provisions contained herein and therein shall not in any way be
affected or impaired thereby. The parties shall endeavor in good-faith
negotiations to replace the invalid, illegal or unenforceable provisions with
valid provisions, the economic effect of which comes as close as possible to
that of the invalid, illegal or unenforceable provisions.
