                           STOCK TRANSFER AGREEMENT

     THIS STOCK TRANSFER AGREEMENT (this "Agreement") is entered into on June
12, 2001, by and between QUANTUM TECHNOLOGIES WORLDWIDE, INC., a Delaware
corporation (the "Company"), and GENERAL MOTORS CORPORATION, a Delaware
corporation ("GM").

                                   RECITALS

     A.   This Agreement is one of several agreements to be entered into by the
Company and GM concurrently, which additional agreements include that certain
Corporate Alliance Agreement (the "Alliance Agreement"), that certain Master
Technical Development Agreement (the "Development Agreement") and that certain
Registration Rights Agreement (the "Registration Rights Agreement").  The
Alliance Agreement, the Development Agreement and the Registration Rights
Agreement shall sometimes be referred to herein collectively as the
"Transactional Agreements."

     B.   This Agreement and each of the Transactional Agreements shall be
effective as of the date of the Closing (as hereinafter defined).

     C.   Following the execution of this Agreement and the Transactional
Agreements and prior to the Closing, IMPCO Technologies Inc., a Delaware
corporation and the parent of the Company ("IMPCO"), and the Company, intend to
effectuate a tax-free distribution of the Company (the "Spin-Off") in full
compliance with all of the requirements of Section 355 (including Section
355(e)) of the Internal Revenue Code of 1986, as amended ("IRC").  The Company
and GM hereby acknowledge that the terms set forth in this Agreement and the
Transactional Agreements and the transactions contemplated hereby and thereby
are intended in their application to meet the requirements of IRC Section 355
(and Section 355(e)) and hereby agree to cooperate with one another and to
conduct the transactions contemplated herein and therein in such a manner as to
achieve that objective.

     D.   The Company intends to effect the Spin-Off in contemplation of
conducting an initial public offering of the Company's securities to the general
public ("IPO") pursuant to a registration statement to be filed under the
Securities Act in connection with or following the date of the Spin-Off.

     NOW, THEREFORE, in consideration of the mutual covenants and agreements set
forth herein, and for other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties hereto hereby agree as
follows:
<PAGE>

                                   ARTICLE 1

                             ACQUISITION OF SHARES

     1.1  Defined Terms.

          Capitalized terms not specifically defined herein (including in
Article 13 hereof) are as defined in the Development Agreement.

     1.2  Transfer.

          (a)  On the terms and conditions set forth in this Agreement, the
Company agrees to transfer to GM, and GM agrees to acquire, at the Closing, that
number of shares of the Company's Series A Common Stock, $0.001 par value per
share (the "Acquired Shares"), which, when combined with all shares of capital
stock of the Company then issued and outstanding, shall equal twenty percent
(20%) of the issued and outstanding shares of capital stock of the Company.

          (b)  The Acquired Shares shall have the rights, privileges and
restrictions as set forth in the Restated Certificate of Incorporation, a copy
of which is attached hereto as Exhibit "A" (the "Certificate"), which the
                               -----------
Company will, prior to the Closing, adopt and file with the Secretary of State
of the state of Delaware.  Such rights, privileges and restrictions shall
specifically provide for anti-dilution protection whereby the number of Acquired
Shares transferred hereunder shall automatically adjust to equal twenty percent
(20%) of the issued and outstanding shares of capital stock of the Company
through the closing of the IPO whereupon it shall convert to Common Stock.  The
Board of Directors shall reserve a sufficient number of authorized shares of its
Common Stock for issuance upon conversion of the Acquired Shares.  Except for
having such additional rights, privileges and preferences as set forth in the
Certificate, the Acquired Shares shall be treated in this Agreement in the same
manner as, and be considered as constituting, shares of the Company's ordinary
Common Stock.

          (c)  The transfer of the Acquired Shares shall take place immediately
following the effectiveness of the Spin-Off at the offices of the Company or at
such other location as the Company and GM shall agree (the "Closing").  At the
Closing, each of the Company and GM shall take such action and deliver all such
funds, documents, certificates and other items as may be required, under this
Agreement or otherwise, in order to perform or fulfill all covenants,
conditions, and agreements on its part to be performed or fulfilled at or before
the Closing.

                                      -2-
<PAGE>

     1.3  Consideration.

          The consideration to be paid by GM for the Acquired Shares shall be
substantially as described in and limited by the Alliance Agreement and the
Development Agreement, and consist of the following:

          (a)  Cash.  In addition to such other consideration as is set forth in
               ----
this Section 1.3, GM shall pay to the Company at the Closing such amount of cash
as is equal to the aggregate par value of the Acquired Shares.

          (b)  Support. GM shall actively support the Company in the performance
               -------
of the Company's duties under the Alliance Agreement and the Development
Agreement and all other agreements related thereto by providing the following to
the Company:

               1.  Access to GM industry expertise;

               2.  Introductions to significant individuals in the industry; and

               3.  Introductions to GM customer base for the GM Fuel Cell
Systems.

          (c)  Endorsement.  GM shall publicly endorse the Company by using
               -----------
reasonable efforts to introduce and recommend the Company as a source of the
business, and as a recommended partner for the design and supply of gaseous
storage and handling systems and sub-systems, as appropriate.

          (d)  Directed Research and Development. GM shall use its expertise and
               ---------------------------------
knowledge of the relevant markets to direct such research and development to be
performed by the Company as shall be determined appropriate to enhance the
relevant business and speed its commercialization in transportation, mobile,
stationary, portable and infrastructure applications, particularly in the areas
of advanced gaseous storage, handling, control and integration with Fuel Cell
Systems.

          (e)  Guidance.  As part of the collaborative efforts of the parties to
               --------
this Agreement, GM shall provide the Company with guidance in the following
areas, among others, to enhance resource and skill sets:

               1.   The evaluation of future technology, testing procedures and
general marketing proposals;

                                      -3-
<PAGE>

               2.   Fuel Cell System requirements for steady state and transient
operation, and the gaseous storage and handling interface and performance
targets to satisfy those requirements;

               3.   The evaluation of resource and facility needs; and

               4.   The coordination of personnel and research and development,
which may include the sharing or exchange of staff and resources.

          (f)  Licenses. GM shall provide the Company with appropriate
               --------
foreground and background technology licenses necessary for the Company to
distribute Quantum Products.

                                   ARTICLE 2
                       GM REPRESENTATIONS AND WARRANTIES


     GM hereby represents and warrants the following:

     2.1  Organization; Qualification; Good Standing.

          GM is a corporation duly incorporated, validly existing and in good
standing under the laws of the state of Delaware.  GM has all requisite power
and authority to carry on its business as presently conducted, to execute and
deliver this Agreement and to carry out the transactions contemplated herein.
GM is duly qualified to transact business and is in good standing in each
jurisdiction in which the failure to be so qualified would have a material
adverse effect on its business or property.

     2.2  Authorization of Agreement.

          The execution, delivery and performance by GM of this Agreement have
been duly authorized by all requisite action of GM and its Board of Directors.
This Agreement has been duly executed and delivered by GM and constitutes a
valid and binding obligation of GM, enforceable against GM in accordance with
its terms, except (i) as limited by applicable bankruptcy, insolvency,
reorganization, moratorium, fraudulent conveyance and other laws of general
application affecting enforcement of creditors' rights generally, and (ii) as
limited by laws relating to the availability of specific performance, injunctive
relief or other equitable remedies.

     2.3  Securities Representations.

          In connection with the issuance and acquisition of Acquired Shares
under this Agreement, GM hereby represents and warrants to the Company as
follows:

                                      -4-
<PAGE>

          (a)   GM is an "accredited investor" within the meaning of SEC Rule
501 of Regulation D, as presently in effect.

          (b)   GM is acquiring and will hold the Acquired Shares for investment
for its account only and not with a view to, or for resale in connection with,
any "distribution" thereof within the meaning of the Securities Act.

          (c)   GM understands that the Acquired Shares have not been registered
under the Securities Act by reason of a specific exemption therefrom and that
the Acquired Shares must be held indefinitely, unless they are subsequently
registered under the Securities Act or GM obtains an opinion of counsel, in form
and substance satisfactory to the Company and its counsel, that such
registration is not required.  GM further acknowledges and understands that the
Company is under no obligation to register the Acquired Shares, except as the
parties hereto may expressly agree in that certain Registration Rights Agreement
of even date herewith attached hereto as Exhibit "B" or otherwise.
                                         -----------

          (d)   GM will not sell, transfer or otherwise dispose of the Acquired
Shares in violation of the Securities Act, the Exchange Act, or the rules
promulgated thereunder, including Rule 144 under the Securities Act.  GM agrees
that it will not dispose of the Acquired Shares unless and until it has complied
with all requirements of this Agreement applicable to the disposition of
Acquired Shares and it has provided the Company with written assurances, in
substance and form satisfactory to the Company, that (1) the proposed
disposition does not require registration of the Acquired Shares under the
Securities Act or all appropriate action necessary for compliance with the
registration requirements of the Securities Act or with any exemption from
registration available under the Securities Act (including Rule 144) has been
taken and (2) the proposed disposition will not result in the contravention of
any transfer restrictions applicable to the Acquired Shares under the securities
laws of any state or the rules promulgated thereunder.

          (e)   The Company, a wholly-owned subsidiary of IMPCO, formerly
conducted its business as an operating segment of IMPCO known as the Automotive
OEM Division.  GM acknowledges and agrees that IMPCO's existing periodic filings
pursuant to the Exchange Act historically discussed the Company as a separate
segment of IMPCO and provided certain information about the business activities
that are now being conducted by the Company.  GM acknowledges that it has been
furnished with, and has had access to, such information as it considers
necessary or appropriate for deciding whether to invest in the Acquired Shares,
and GM has had an opportunity to ask questions and receive answers from the
Company regarding the terms and conditions of the issuance of the Acquired
Shares.

                                      -5-
<PAGE>

          (f)  GM is aware that its investment in the Company is a speculative
investment that has limited liquidity and is subject to the risk of complete
loss. GM is able, without impairing its financial condition, to hold the
Acquired Shares for an indefinite period and to suffer a complete loss of its
investment in the Acquired Shares.

     2.4  Securities Law Restrictions.

     Regardless of whether the offering and transfer of Acquired Shares under
this Agreement have been registered under the Securities Act or have been
registered or qualified under the securities laws of any state, the Company at
its discretion may impose restrictions upon the sale, pledge or other transfer
of the Acquired Shares (including the placement of appropriate legends on stock
certificates or the imposition of stop-transfer instructions) if, in the
judgment of the Company, such restrictions are necessary or desirable in order
to achieve compliance with the Securities Act, the securities laws of any state
or any other law.

     2.5  Market Stand-Off.

          GM agrees that it shall not, to the extent requested by the Company
and an underwriter of Common Stock (or other securities) of the Company, sell or
otherwise transfer or dispose (other than to donees who agree to be similarly
bound) any Common Stock (or other securities) of the Company for one hundred
eighty (180) days following the effective date of a registration statement of
the Company filed under the Securities Act in connection with the IPO, and for
ninety (90) days following the effective dates of each of the first two (2)
registrations thereafter, provided that such registrations become effective
within three years of such closing date.  To enforce the agreement contained in
this Section 2.5, the Company may impose stop-transfer instructions with respect
to Common Stock held by GM until the end of such periods.  The Company's
underwriters shall be beneficiaries of the agreement set forth in this Section
2.5.

     2.6  Rights of the Company.

     The Company shall not be required to (a) transfer on its books any Acquired
Shares that have been sold or transferred in contravention of this Agreement or
(b) treat as the owner of Acquired Shares, or otherwise to accord voting,
dividend or liquidation rights to, any transferee to whom Acquired Shares have
been transferred in contravention of this Agreement.

     2.7  Ownership of Securities.

                                      -6-
<PAGE>

          None of GM or its Affiliates own, nor have any option or right to
acquire, directly or indirectly, any capital stock or other securities of IMPCO
or the Company, other than the Acquired Shares, provided that a pension plan or
profit sharing plan that does not buy, sell or vote securities at the order,
direction or recommendation of GM shall not be deemed to be an Affiliate of GM.

     2.8  Future Acquisitions.

          None of GM or any of its Affiliates has any plan or intention to
acquire, directly or indirectly, any capital stock or other securities of IMPCO
or the Company, other than the Acquired Shares, provided that a pension plan or
profit sharing plan that does not buy, sell or vote securities at the order,
direction or recommendation of GM shall not be deemed to be an Affiliate of GM.

                                   ARTICLE 3
                               TRANSFER OF SHARES

     3.1  Right of First Refusal.

          In the event that GM proposes to sell, assign, pledge, transfer or
otherwise convey ("Transfer") any Acquired Shares or other similar evidence of
equity ownership or interest in the Company (collectively, the "Offered
Shares"), to a third party not affiliated with GM in one or more related bona
fide arms-length transactions (a "Transaction"), then GM and/or its assignee(s)
shall offer in writing to the Company the right to purchase the Offered Shares
on the same terms and conditions (subject, however, to any change of terms
permitted under Section 3.3 below) as set forth in such written notice (the
"Transfer Notice").  The Transfer Notice shall include (i) a description of the
Offered Shares, (i) the identity of the prospective transferee(s), (iii) the
consideration and the material terms and conditions upon which the proposed
Transfer is to be made and (iv) the expected closing date for the Transaction.
The Transfer Notice shall also include a copy of any written proposal, term
sheet or letter of intent or other agreement relating to the proposed Transfer,
and GM shall certify that it has a good faith belief that a binding agreement
for the Transfer is obtainable on the terms described in, or attached to, the
Transfer Notice.

     3.2  Exercise of Right of First Refusal.

          Within thirty (30) calendar days after the date of receipt of the
Transfer Notice, the Company may notify GM in writing of the Company's desire to
purchase from GM all, but not less than all, of the Offered Shares at the same
price, and upon the same terms (or terms as similar as reasonably possible) as
described in the

                                      -7-
<PAGE>

Transfer Notice, and GM shall sell the Offered Shares to the Company pursuant to
such terms.

     3.3  Transfer of Shares.

          If the Company and/or its assignee(s) fail to exercise their Right of
First Refusal to purchase all, but not less than all, of the Offered Shares
within thirty (30) calendar days after the date of receipt of the Transfer
Notice, GM may, not later than ninety (90) calendar days following receipt of
the Transfer Notice by the Company, conclude a transfer of the Offered Shares
subject to the Transfer Notice on the terms and conditions described in the
Transfer Notice, provided that any such sale is made in compliance with
applicable federal and state securities laws and not in violation of any other
contractual restrictions to which GM is bound, and provided further, that the
Transferee agrees, prior to such transfer, to receive and hold the Offered
Shares subject in all respects to the provisions of this Agreement.  Any
proposed transfer on terms and conditions materially different from those
described in the Transfer Notice, as well as any subsequent proposed transfer by
GM, shall again be subject to the Right of First Refusal and shall require
compliance with the procedure described in Section 3.1 above.  If the Company
and/or its assignee(s) exercise the Right of First Refusal and purchase all of
the Offered Shares, the parties shall consummate the sale of the Offered Shares
on the terms set forth in the Transfer Notice within sixty (60) calendar days
after the date when the Company received the Transfer Notice (or within such
longer period as may have been specified in the Transfer Notice); provided,
however, that in the event the Transfer Notice provided that payment for the
Offered Shares was to be made in a form other than cash or cash equivalents paid
at the time of transfer, the Company or its assignee(s) shall have the option of
paying for the Offered Shares with cash or cash equivalents equal to the Fair
Market Value of the consideration described in the Transfer Notice.

     3.4  Additional Shares or Substituted Securities.

          In the event of the declaration of a stock dividend, the declaration
of an extraordinary dividend payable in a form other than stock, a spin-off, a
stock split, an adjustment in conversion ratio, a recapitalization or a similar
transaction affecting the Company's outstanding securities without receipt of
consideration, any new, substituted or additional securities or other property
(including money paid other than as an ordinary cash dividend) which are by
reason of such transaction distributed with respect to any Acquired Shares
subject to this Article 3 or into which such Acquired Shares thereby become
convertible shall immediately be subject to this Article 3 and shall, for all
purposes of this Agreement, be considered as Acquired Shares.

                                      -8-
<PAGE>

Appropriate adjustments to reflect the distribution of such securities or
property shall be made to the number and/or class of Acquired Shares subject to
this Article 3.

     3.5  Termination of Right of First Refusal.

          The Right of First Refusal shall terminate and be of no force and
effect immediately upon the earliest to occur of (a) the first date on which the
Company's Common Stock is held of record by more than five hundred (500)
persons, (b) a determination is made by the Board of Directors that a public
market exists for the outstanding Acquired Shares, or (c) the effective date of
a firm commitment underwritten public offering, pursuant to an effective
registration statement on Form S-1 or Form SB-2 under the Securities Act,
covering the offer and sale of the Company's Common Stock.  Notwithstanding the
foregoing language contained in this Section 3.5, the Right of First Refusal
shall continue for a period of three (3) years following the date of this
Agreement with respect to any negotiated transaction between GM and any other
Person.  The effectiveness of the Market Stand-Off set forth in Section 2.5
shall not be affected by the termination of this Right of First Refusal.

     3.6  Termination of Rights as Stockholder.

          If the Company or its assignee(s) make available, at the time and
place and in the amount and form provided in this Agreement, the consideration
for the Offered Shares to be Acquired in accordance with Section 3.3 above, then
after such time the person from whom such Offered Shares are to be Acquired
shall no longer have any rights as a holder of such Offered Shares (other than
the right to receive payment of such consideration in accordance with this
Agreement).  Such Offered Shares shall be deemed to have been Acquired in
accordance with the applicable provisions hereof, whether or not the
certificate(s) therefor have been delivered as required by this Agreement.  In
the event such certificate(s) are not delivered as required hereunder, GM hereby
irrevocably constitutes and appoints any duly elected secretary of the Company
to transfer the Offered Shares on the books of the Company with full power of
substitution.

     3.7  Compliance with IRC Section 355.

          None of GM or its Affiliates shall take or fail to take any action
that could cause or reasonably be expected to contribute to the failure of the
Spin-Off to qualify under IRC Section 355 or that could cause or reasonably be
expected to cause the provisions of IRC Section 355(e) to apply to those
transactions.

              -----------

                    ------------------------
the number of outstanding shares of Series A Common shall be subject to
adjustment from time to time upon the occurrence of certain events, the purpose
of which adjustment or adjustments shall be for the number of shares of issued
and outstanding Series A Common to equal twenty percent (20%) of the issued and
outstanding shares of all series of Common Stock of the Corporation (the "Issued
and Outstanding Common Shares"); provided, however, that the Issued and
Outstanding Common Shares shall specifically exclude any shares of Common Stock
and options therefor issued to directors, officers, employees or consultants of
the Corporation pursuant to a stock option or other equity incentive plan or
agreement approved by the Board of Directors of the Corporation (a "Plan").

                    4.1(a)  Upon the happening of an Extraordinary Common Stock
Event (as defined below) after June 12, 2001, the number of outstanding shares
of Series A Common shall be adjusted to a number equal to that number of shares
of Common Stock determined by multiplying the number of the then Issued and
Outstanding Common Shares by twenty percent (20%). The adjustment shall occur
automatically without the need for any action by the holders of such shares and
whether or not the certificates representing such shares are surrendered to the
Corporation or its transfer

agent; provided, however, that the Corporation shall not be obligated to issue
certificates evidencing the shares of Series A Common issuable upon such
adjustment but shall maintain adequate records, accessible to each holder of
Series A Common, setting forth the effective date of the adjustment, the amount
of the required adjustment and the computation thereof. The number of shares of
outstanding Series A Common, as so adjusted, shall be readjusted in the same
manner upon the happening of any successive Extraordinary Common Stock Event or
Events.

                    4.1(b)  "Extraordinary Common Stock Event" shall mean (i)
the issuance of additional shares of Common Stock other than shares of Common
Stock and options therefore issued pursuant to a Plan; (ii) the issuance of
additional shares of Common Stock as a dividend or other distribution on
outstanding Common Stock of the Corporation, (iii) a subdivision of outstanding
shares of Common Stock into a greater number of shares of Common Stock, of (iv)
a combination of outstanding shares of Common Stock into a smaller number of
shares of Common Stock.

               4.2  Automatic Conversion.  Upon the closing of an initial
                    --------------------
public offering of the Corporation's securities to the general public ("IPO")
pursuant to a registration statement of the Corporation filed under the
Securities Act of 1933, as amended to date, the outstanding shares of Series A
Common shall automatically be converted into that number of shares of Common
Stock that would be equal to twenty percent (20%) of the Issued and Outstanding
Common Shares immediately following the closing of the IPO. The Corporation
shall, as soon as practicable after the closing date of the IPO (the "Closing
Date"), issue and deliver to the holder of the outstanding shares of Series A
Common, a certificate or certificates for the number of shares of Common Stock
to which it shall be entitled as aforesaid. Such conversion shall be deemed to
have been made immediately prior to the close of business on the Closing Date,
and the person or persons entitled to receive the shares of Common Stock
issuable upon such conversion shall be treated for all purposes as the record
holder or holders of such shares of Common Stock. Upon such conversion and
notwithstanding that the certificates evidencing such shares of Series A Common
shall not have been surrendered, the shares so converted shall be deemed
canceled and shall not be issuable by this Corporation, the rights of the
holders of the Series A Common with respect to such shares shall terminate and
the authority of the Corporation to issue shares of Series A Common Stock shall
terminate. The Certificate of Incorporation of this Corporation shall be
appropriately amended to effect the change in the Corporation's authorized
capital stock.

                             V.  Board of Directors

     The Board of Directors is expressly authorized to make, alter, or repeal
the Bylaws of the Corporation.

                           VI.  Election of Directors

     Elections of directors need not be by written ballot unless the Bylaws of
the Corporation shall so provide.  The number of directors shall be fixed from
time to time by the Board of Directors pursuant to a resolution adopted by a
majority of the total number of authorized directors (whether or not there exist
any vacancies in the previously authorized directorships at the time any such
resolution is presented to the Board for adoption).

                                VII.  Creditors

     Whenever a compromise or arrangement is proposed between the Corporation
and its creditors or any class of them and/or between the Corporation and its
stockholders or any class of them, any court of equitable jurisdiction within
the State of Delaware may, on the application in a summary way of the
Corporation or of any creditor or stockholder thereof, or on the application of
any receiver or receivers appointed for the Corporation under the provisions of
Section 291 of Title 8 of the Delaware Code or on the application of trustees in
dissolution or of any receiver or receivers appointed for the Corporation under
the provisions of Section 279 of Title 8 of the Delaware Code order a meeting of
the creditors or class of creditors, and/or of the stockholders or class of
stockholders of the Corporation, as the case may be, to be summoned in such
manner as the said court directs.  If a majority in number representing three-
fourths in value of the creditors or class of creditors, and/or the stockholders
or class of stockholders of the Corporation, as the case may be, agree to any
compromise or arrangement and to any reorganization of the Corporation as a
consequence of such compromise or arrangement, the said compromise or
arrangement and the said reorganization shall, if sanctioned by the court to
which the said application has been made, be binding on all the creditors or
class of creditors, and/or on all the stockholders or class of stockholders, of
the Corporation, as the case may be, and also on the Corporation.

                               VIII.  Amendments

     The Corporation reserves the right to amend, alter, change or repeal any
provision contained in this Certificate of Incorporation, in the manner now or
hereafter prescribed by statutes, and all rights conferred upon stockholders
herein are granted subject to this reservation.

                            IX.  Director Liability

     A director of the Corporation shall not be personally liable to the
Corporation or its stockholders for monetary damages for breach of fiduciary
duty as a director, except for liability (i) for any breach of the director's
duty of loyalty to the Corporation or its stockholders, (ii) for acts or
omissions not in good faith or which involve intentional

misconduct or a knowing violation of law, (iii) under Section 174 of the
Delaware General Corporation Law, or (iv) for any transaction from which the
director derived any improper personal benefit. If the Delaware General
Corporation Law is amended after approval by the stockholders of this Article to
authorize corporation action further eliminating or limiting the personal
liability of directors, then the liability of a director of the Corporation
shall be eliminated or limited to the fullest extent permitted by the Delaware
General Corporation Law as so amended.

Amendment to be signed by its duly authorized officer this __ day of

Rights. I agree to keep and maintain adequate and current written records of all

the Company at all times. I will not contest the validity of any Proprietary
Right, or aid or encourage any third party to contest the validity of any
Proprietary Right of the Company.

     If the Company is unable for any reason to secure my signature to fulfill
the intent of the foregoing paragraph or to apply for or to pursue any
application for any United States or foreign patents or copyright registrations
covering Inventions assigned to the Company above, then I irrevocably appoint
the Company and its authorized agents as my agent and attorney in fact, to

applications and to do all other lawful acts to further the prosecution and
issuance of letters patent or copyright registrations with the same legal force

employment with the Company.  I will not take advantage of or divert any such
opportunity for the benefit of myself or anyone else either during or after the
Term without the prior written consent of the Company.

authorship, developments, improvements, and trade secrets which were made by me
prior to the Term (collectively referred to as "Prior Inventions"), which belong
to me, which relate to the Company's current or proposed business, products or
research and development, and which are not assigned to the Company hereunder;
or, if no such list is attached, I represent that there are no such Prior
Inventions.  If, during the Term, I incorporate into a Company product, process
or machine a Prior Invention owned by me or in which I have an interest, the
Company is granted and shall have a nonexclusive, royalty-free, irrevocable,
perpetual, worldwide license to make, have

made, modify, use and sell such Prior Invention as part of or in connection with
such product, process or machine.

     3.6    Labor Code Section 2870 Notice.  I have been notified and understand
that the provisions of Sections 3.1 and 3.2 of this Agreement do not apply to
any Invention assigned hereunder that qualifies fully under the provisions of
Section 2870 of the California Labor Code, which states as follows:

            ANY PROVISION IN AN EMPLOYMENT AGREEMENT WHICH PROVIDES
            THAT AN EMPLOYEE SHALL ASSIGN, OR OFFER TO ASSIGN, ANY
            OF HIS OR HER RIGHTS IN AN INVENTION TO HIS OR HER
            EMPLOYER SHALL NOT APPLY TO AN INVENTION THAT THE
            EMPLOYEE DEVELOPED ENTIRELY ON HIS OR HER OWN TIME
            WITHOUT USING THE EMPLOYER'S EQUIPMENT, SUPPLIES,
            FACILITIES, OR TRADE SECRET INFORMATION EXCEPT FOR
            THOSE INVENTIONS THAT EITHER: (1) RELATE AT THE TIME OF
            CONCEPTION OR REDUCTION TO PRACTICE OF THE INVENTION TO
            THE EMPLOYER'S BUSINESS, OR ACTUAL OR DEMONSTRABLY
            ANTICIPATED RESEARCH OR DEVELOPMENT OF THE EMPLOYER; OR
            (2) RESULT FROM ANY WORK PERFORMED BY THE EMPLOYEE FOR
            THE EMPLOYER. TO THE EXTENT A PROVISION IN AN
            EMPLOYMENT AGREEMENT PURPORTS TO REQUIRE AN EMPLOYEE TO
            ASSIGN AN INVENTION OTHERWISE EXCLUDED FROM BEING
            REQUIRED TO BE ASSIGNED UNDER CALIFORNIA LABOR CODE
            SECTION 2870(a), THE PROVISION IS AGAINST THE PUBLIC
            POLICY OF THIS STATE AND IS UNENFORCEABLE.

     3.7    Inventions Assigned to the United States.  I agree to assign to the
United States government all my right, title and interest in and to any and all
Inventions whenever such full title is required to be in the United States by a
contract between the Company and the United States or any of its agencies.

     4.3  I will not use in performance of my work for the Company or disclose
to the Company any trade secret, confidential or proprietary information of any
prior employer or other Person if and to the extent that such use or disclosure
may cause a breach, default or violation of any obligation or duty that I owe to
such other Person (e.g., under any agreement or applicable law).  My compliance
with this Section 4.3 will not prohibit, restrict or impair the performance of
my work, obligations and duties to the Company.

Section 5.  Nonsolicitation

     5.1  Employees/Consultants.  During the Term and for one year after the end
of the Term (the "Additional Period"), I will not induce, or attempt to induce,
any employee or consultant of the Company to cease such employment or
relationship to engage in, be employed by, perform services for, participate in
the ownership, management, control or operation of, or otherwise be connected
with, either directly or indirectly, any Competing Business.

     5.2  Suppliers/Contractors.  During the Term and for the Additional Period,
I agree (except on behalf of or with the prior written consent of the Company)
that I will not, directly or indirectly (a) solicit, divert, appropriate to or
accept on behalf of any Competing Business, or (b) attempt to solicit, divert,
appropriate to or accept on behalf of any Competing Business, any business from
any customer or actively sought prospective customer of the Company with whom I
have dealt, whose dealings with the Company have been supervised by me or about
whom I have acquired Confidential Information in the course of my employment.

Section 6.  Termination of Relationship

     6.1  I agree that at the end of the Term I will deliver to the Company (and

Materials and other property belonging to the Company, its successors, assigns,
customers and/or development partners.  I agree to sign and deliver the

     6.2    At the end of the Term, I agree to provide the name of my new
employer, if any, and consent to notification by the Company to my new employer
about my rights and obligations under this Agreement in the form of Exhibit D.

Section 7.  Employment At Will

     I understand that this Agreement does not obligate the Company to employ me
for any stated period of time.  I understand that my employment is "at will"
which means that it can be terminated at any time by the Company or by me, with
or without cause and with or without notice.  I agree that any promise or
obligation that my employment be on any other basis than "at will" is invalid
unless in writing signed by the president of the Company.  I agree to abide by
the Company's rules, regulations, policies and practices as revised from time to
time.

     [NOTE:  The above provision will be deleted in its entirety or
substantially modified in the form of Inventions and Confidential Information
Agreement for individuals with employment agreements.]

Section 8.  Miscellaneous

     7.1    Survival.  This Agreement will survive the end of the Term.

     7.2    Successors and Assigns; Assignment.  Except as otherwise provided in
this Agreement, this Agreement and the rights and obligations of the parties
hereunder will be binding upon and inure to the benefit of their respective
successors, assigns, heirs, executors, administrators and legal representatives.
The Company may assign any of its rights and obligations under this agreement.
I understand that I may not assign, whether voluntarily or by operation of law,
any of my rights and obligations under this Agreement, except with the prior
written consent of the Company.

     7.3    Injunctive Relief; Costs.  I acknowledge that my obligations under
this Agreement are important to the Company, and that the Company would not
employ or continue to employ me without my agreement to such obligations.  I
also acknowledge that if I do not abide by my obligations in this Agreement, the
Company will suffer immediate and irreparable harm, and that the damage to the
Company will be difficult to measure and financial relief will be incomplete.
Accordingly, the Company will be entitled to injunctive relief and other
equitable remedies in the event of a breach by me of any obligation under this
Agreement.  The rights and remedies of the Company under this section are in
addition to all other remedies.  Further, in any legal action or other
proceeding in connection with this Agreement (e.g., to recover damages or other
relief), the prevailing party will be entitled to recover its reasonable
attorneys' fees and other costs incurred.

by the laws of the state of California without regard to principles of conflicts
of law.  I irrevocably consent to the jurisdiction and venue of the state and
