            (i)   During my service as an employee of the Company and for a
                  period of six (6) months thereafter, I will promptly and fully
                  disclose to the Company (and to any persons designated by it)
                  all Inventions generated, made, conceived or reduced to
                  practice or learned by me, either alone or jointly with
                  others, which, in any way, result from or is suggested by any
                  work which I may do for or on behalf of the Company; or relate

                  from the use of premises or property owned, leased, licensed,

                  rights to such Inventions, whether they are patentable or not.

            (ii)  I understand that the Company will have no rights pursuant to
                  this Agreement in any Invention of mine made during the term
                  of my employment by the Company if such Invention has not
                  arisen out of or by reason of my work with the Company, and
                  does not relate to the business or operations of the Company,

            connection therewith. I hereby assign to the Company any and all

                                                                   H Power Corp.
                                               Employee Non Disclosure Agreement

            to assist the Company in every proper way (but at the Company's
            expense) to obtain, and from time to time enforce, patents,
            copyrights, trademarks, trade secrets, and other rights and
            protections relating to said Inventions in any and all countries,
            and to that end I will execute all documents for use in applying for
            and obtaining such patents, copyrights, trademarks, trade secrets
            and other rights and protections on, and enforcing, such Inventions,
            as the Company may desire, together with any assignments thereof to
            the Company or persons designated by it.

            My obligation to assist the Company in obtaining and enforcing
            patents, copyrights, trademarks, trade secrets, and other rights and
            protections relating to such Inventions in any and all countries
            shall continue beyond the termination of my employment by the
            Company, but the Company shall compensate me at a reasonable rate
            after my termination for time actually spent by me, at the Company's
            request, on such assistance. In the event the Company is unable,
            after reasonable effort, to secure my signature on any document or
            documents needed to apply for or prosecute any patent, copyright,
            trademark, trade secret, or other right or protection relating to an
            Invention whether because of my physical or mental capacity or for
            any other reason whatsoever, I hereby irrevocably designate and
            appoint the Company its duly authorized officers and agents as my
            agent coupled with an interest and attorney-in- fact, to act for and
            in my behalf and stead to execute and file any such application or
            applications and to do all other lawfully permitted acts to further
            the prosecution and issuance of patents, copyrights, trademarks,
            trade secrets, or similar rights or protections thereon with the
            same legal force and effect as if executed by me.

      (c)   Previous Inventions

            As a matter of record, I have identified in Exhibit A, attached
            hereto, all Inventions that have been generated or conceived or
            first reduced to practice or learned by me, alone or jointly with
            others, prior to my employment by the Company, which I desire to
            remove from the operation of this Agreement. I represent and warrant
            that such list is complete. If I do not attach a list hereto, I
            represent that I have made no such Inventions at the time of signing
            this Agreement.

6.    LIMITATION ON OTHER ACTIVITIES AND COMPETITION

      (a)   During Employment

            I agree that while I am employed by the Company I will not, without
            the Company's express written consent, engage in any consulting,
            employment or business that is competitive with the Company. In
            furtherance and not in limitation of the generality of the preceding
            sentence, I shall not, for myself or on behalf of any person or

            organization, directly or indirectly, compete with the Company in
            the development, manufacture, sale, solicitation or servicing of any
            then existing product of, or service or business engaged in by, the
            Company, or any other product of, or service or business engaged in,
            or under development by, the Company.

      (b)   After Termination of Employment

            If I have had significant contact with customers of the Company
            while employed by the Company, or if I have been materially involved
            in the design, development or implementation of the Company's
            present or planned major products or services, then I agree that the
            provisions of Paragraph 6(a) hereinabove shall be expanded to
            prohibit my competing with the Company for twelve (12) months
            following the termination of my employment.

7.    NO CONFLICTING OBLIGATIONS

      (a)   During Employment

            I represent and warrant to the Company that I have no interest or
            obligation which is inconsistent with or in conflict with this
            Agreement, or which would prevent, limit or impair my performance of
            any part of this Agreement. I agree to notify the Company
            immediately if any such interest or obligation arises.

      (b)   After Termination of Employment

            For twelve (12) months following the termination of my employment by
            the Company, I agree that if I accept employment, whether as a
            consultant, employee, director, trustee or otherwise, with any
            person or organization, or engage in any type of activity on my
            behalf or on behalf of any person or organization that is in any way
            related to the products, services or business of the Company, I
            shall notify the Company in writing, within thirty (30) days
            thereof, of the character of each such activity, and of the name and
            address of each such person or organization by which I am so
            employed.

8.    CONFIDENTIALITY OF PREVIOUS EMPLOYERS

      I represent that my performance of all the terms of this Agreement does
      not and will not breach any agreement to keep in confidence proprietary
      information acquired by me in confidence or in trust prior to the
      execution of this Agreement. I have not entered into, and I agree that I
      will not enter into, any agreement, either written or oral, in conflict
      with this Agreement.

                                               Employee Non Disclosure Agreement

      I represent that I have not brought and will not bring with me to the
      Company, or use in the performance of my responsibilities at the Company,
      any materials or documents of a present or former employer or client that
      are not generally available to the public, unless I have obtained express
      written authorization from the present or former employer or client for
      their possession and use.

      I also understand that at no time during my service to the Company am I to
      breach any obligation of confidentiality that I have to present or former
      employers or clients, and I agree that I shall fulfill all such
      obligations to present or former employers and clients during my service
      to the Company.

9.    ENFORCEMENT

      inadequate, and the Company shall be entitled to an injunction to enforce
      such provisions (without any bond or other security being required), but
