                                             Virginia, Delaware, Maryland, West
                                             Virginia and the District of
                                             Columbia. The Parties shall work
                                             together constructively to find an
                                             appropriate role for ECO Fuel
                                             Cells' Cooperatives in this
                                             agreement.

                                    iv.      Specialty Fuel Cell Products are
                                             excluded from the above
                                             requirements in this section b.

                           Notwithstanding the above, in all cases each Party
                           shall report to the other Party within thirty (30)
                           days of execution, any exclusive agreements that have
                           been executed.

                  c.       DISTRIBUTION AGREEMENTS. ECO Fuel Cells has entered
                           into numerous Distributive Generation Products and
                           Fuel Cell Licensing Agreements ("Distribution
                           Agreements") under which exclusive distribution
                           rights for H Power's Fuel Cell Power Systems have
                           been granted to Licensed Members and other parties,
                           (the "Licensees"). Licensees shall be notified by ECO
                           Fuel Cells that ECO Fuel Cells wishes to cancel and
                           renegotiate their Distribution Agreements and convert
                           them to non-exclusive Distribution Agreements. If the
                           Licensee nevertheless desires to continue with an
                           Exclusive Distribution Agreement, then H Power's
                           obligations shall continue and shall be no greater
                           than under the existing or pending Distribution
                           Agreement as of the date hereof. Any existing,
                           pending as of the date of this Agreement, or
                           renegotiated exclusive Distribution Agreements are
                           called "Grandfathered Distribution Agreements"
                           herein. ECO Fuel Cells shall provide a list of
                           Grandfathered Distribution Agreements to H Power once
                           they have been renegotiated but not later than March
                           31, 2002. Otherwise, all obligations and liabilities
                           of H Power with respect to Distribution Agreements
                           shall be assumed by ECO Fuel Cells and H Power shall
                           have no further obligations thereunder. No fees shall
                           be paid to H Power for those Licensees that have
                           selected or will select the "Fuel Cell Distribution
                           Option" or who select a Non-Exclusive Option as
                           defined in the Distribution Agreement.

                  d.       DISTRIBUTION AGREEMENT FEES. Regarding those ECO Fuel
                           Cell Licensees that continue with a Grandfathered
                           Distribution Agreement, ECO Fuel Cells shall pay the
                           OHU fees to H Power that are specified in Article
                           3.B. of this Agreement within sixty (60) days after
                           the Commercial Date.

                  e.       TESTING AGREEMENTS. In addition, ECO Fuel Cells shall
                           be responsible for renegotiating the "Fuel Cell
                           Testing Agreements Between the Cooperatives and ECO
                           Fuel Cells" (the "Testing Agreements") with its
                           Licensees. All obligations and liabilities of H Power
                           with respect to these Testing Agreements (including,
                           but not limited to, those set forth in Attachment 3
                           thereto) shall be assumed by ECO Fuel Cells and H
                           Power shall have no further obligations thereunder.
                           It is anticipated that the Parties will continue a
                           Fuel Cell testing program and new Fuel Cell testing
                           agreements will be executed on such terms as are
                           agreed to by the Parties.

         2.       ECO FUEL CELLS' ASSIGNMENT RIGHTS. It is ECO Fuel Cells'
                  intention to assign to Cooperative Members all or some of the
                  Distribution Rights granted herein. ECO Fuel Cells intends to
                  work with Cooperative Members to develop marketing
                  arrangements, which may result in several different
                  strategies. Therefore, to provide ECO Fuel Cells with the
                  necessary marketing and corporate structure flexibility, ECO
                  Fuel Cells shall have the right to assign, sell, license, or
                  otherwise transfer, all or any part of the Distribution Rights
                  to ECO, Licensed Members or to any other entity affiliated
                  with them. All assignments of Distribution Rights by ECO Fuel
                  Cells shall be in writing and consistent with this Agreement.
                  ECO Fuel Cells shall inform H Power in writing forty-five (45)
                  days prior to effecting any assignment pursuant to the terms
                  hereof.

         3.       NON-COMPETITION.

                  a.       H Power agrees that in any Territory where ECO Fuel
                           Cells or its Licensee has exclusive rights from a
                           Grandfathered Distribution Agreement or any exclusive
                           agreement entered into after the date of this
                           Agreement, it will not sell the Fuel Cell Products
                           either directly or knowingly indirectly for use in
                           the Territory except to ECO Fuel Cells or to the
                           Licensee.

                  b.       ECO Fuel Cells agrees that it will not sell the Fuel
                           Cell Products either directly or knowingly indirectly
                           for use outside the United States; or to any future
                           exclusive Licensee of H Power, except as may
                           otherwise be provided in the license terms.

                  c.       This paragraph c. applies only to Grandfathered
                           Distribution Agreements.

                           i        H Power agrees that it will not sell the
                                    Fuel Cell Products either directly or
                                    knowingly indirectly for use in the
                                    "Territory" (defined below) except to ECO
                                    Fuel Cells or to Licensed Members.

                           ii       ECO Fuel Cells agrees that it will not sell
                                    the Fuel Cell Products either directly or
                                    knowingly indirectly for use outside the
                                    Territory. "Territory" is defined as all of
                                    the counties or part thereof in the

                                     Page 7

                                    United States (including the District of
                                    Columbia; and areas that are not a part of
                                    any county, such as Arlington, VA) in which
                                    Cooperative Members were providing energy
                                    services as of August 15, 1999 (including,
                                    but not limited to electricity, natural gas,
                                    propane and other fuels), as set forth in
                                    Schedule B of this Agreement. ECO Fuel Cells
                                    also agrees that it will not sell Fuel Cell
                                    Power Systems that compete with H Power's
                                    Fuel Cell Power Systems; that it will not
                                    sell such Fuel Cell Power Systems (unless
                                    otherwise agreed to by the Parties) in
                                    counties of Cooperative Members to which no
                                    Distribution Rights have been assigned; and
                                    that it will include the terms set forth in
                                    this paragraph in all assignments of
                                    Distribution Rights to Cooperative Members.

                           iii      In the event that ECO Fuel Cells or the
                                    Licensed Members are able to purchase from
                                    third parties Fuel Cell Power Systems that
                                    are: (1) comparable or superior in quality
                                    and performance to H Power's Fuel Cell
                                    Products; (2) at Unit prices that are at
                                    least [*] H Power's Unit prices; and (3) on
                                    terms and conditions that otherwise are
                                    comparable to H Power's terms and
                                    conditions, then ECO Fuel Cells shall so
                                    notify H Power in writing of such event and
                                    if H Power does not, within 30 days after
                                    receipt of said notice from ECO Fuel Cells,
                                    [*], ECO Fuel Cells and the Licensed Members
                                    may purchase those Fuel Cell Power Systems
                                    from third parties and the restrictions
                                    against selling fuel cells that compete with
                                    H Power as set forth in paragraph ii) above
                                    shall not apply. Thereafter, if the Licensed
                                    Members that maintain Grandfathered
                                    Distribution Agreements [*] H Power during
                                    any subsequent [*] then the exclusive rights
                                    granted under such Grandfathered
                                    Distribution Agreements shall terminate and
                                    all Territory under those distribution
                                    agreements shall convert to non-exclusive
                                    status.

                  d.       DIRECT SALES. Because of ECO Fuel Cell's expertise in
                           distributive generation products and services, and
                           because ECO Fuel Cell's electric Cooperative
                           customers are also ECO Fuel Cell's owners, H Power
                           agrees that ECO Fuel Cells will be its preferred
                           provider of Fuel Cell Products to the U.S. electric
                           Cooperative industry. Therefore, H Power agrees not
                           to enter into any agreement with a U.S. Cooperative
                           (including its affiliate, or a Cooperative
                           association) to sell as a distributor,
                           sub-distributor, marketer, or sales representative of
                           H Powers' Fuel Cell Products, except as may otherwise
                           be provided under this Agreement.

                           However, ECO's members and ECO Fuel Cell's Licensees
                           shall have the option of purchasing Fuel Cell
                           Products from any H Power distributor,
                           sub-distributor, sales representative or similar
                           sales entity of their choice. H Power shall not make
                           direct sales to Cooperatives except through this
                           Agreement, or through its existing third party
                           distribution associates' independent sales efforts.
                           ECO Fuel Cell's Licensees (but not ECO or ECO Fuel
                           Cells) that do not elect to retain or enter into a
                           Grandfathered Distribution Agreement shall have the
                           right to sell Fuel Cell Products other than H
                           Power's. Both ECO Fuel Cells and ECO, however, will
                           exclusively purchase Fuel Cells from H Power.

                  e.       Notwithstanding anything to the contrary contained in
                           this Agreement (including all schedules, appendices
                           and exhibits hereto), subject only to H Power's
                           compliance with its covenants and agreements
                           contained herein, ECO Fuel Cells will purchase or
                           will arrange to have Licensed Members purchase Fuel
                           Cell Products totaling $81,186,000 as provided in
                           Article 4.A. below.

                  4.       FAIR PRICING.
                           In no event shall ECO Fuel Cells or Licensed Members
                           pay more for any of H Power's Fuel Cell Power
                           System(s) and services under this Agreement than
                           others pay for similar quantities or levels of
                           service.

         B.       PAYMENTS UPON ASSIGNMENT OF DISTRIBUTION RIGHTS BY ECO FUEL
                  CELLS TO ECO'S COOPERATIVE MEMBERS. This paragraph only
                  applies to Grandfathered Distribution Agreements in which the
                  Licensee has selected the Territory Purchase Option. ECO Fuel
                  Cells has assigned or intends to assign its Distribution
                  Rights to ECO's Cooperative Members on a county by county
                  basis (the District of Columbia and other areas, e.g.,
                  Arlington, VA, that are not a part of any county will be
                  treated as a county for this purpose). All or part of a county
                  may be assigned. The Cooperative Member to which the
                  Distribution Rights have been assigned shall be deemed to be a
                  "Licensed Member". For exclusive Territory only, within sixty
                  (60) days after the Commercial Date, ECO Fuel Cells will make
                  a one time payment of [*] to H Power for each Occupied Housing
                  unit within each assigned county, or portion thereof, as
                  reflected in (a) the Census of Population and Housing,

                  to H Power products or services other than Fuel Cell Products,
                  on an individual product or service basis. It shall be in H
                  Power's sole discretion whether or not to grant such rights.
                  In the event rights are granted by H Power, then ECO Fuel
                  Cells or Licensed Members shall not pay more to H Power for
                  those products to which rights have been granted than others
                  pay for similar quantities or levels of those products or
                  services.

         D.       IMPROVEMENTS. Any new or improved Fuel Cell Products, design,
                  concept, or other invention (in whole or part thereof) made or
                  developed by H Power, jointly by H Power with others, or
                  jointly by H Power and ECO Fuel Cells in the course of
                  creation, development, distribution or operation of the Fuel
                  Cell Products, will be promptly and completely disclosed to
                  ECO Fuel Cells by H Power. The foregoing sentence is intended

         E.       TRAINING. H Power and ECO Fuel Cells may develop a standard
                  program of training, to be held at H Power's expense at
                  mutually agreed upon intervals and locations. If so, travel
                  and living expenses incurred by ECO Fuel Cells, and Licensed
                  Members' personnel attending training seminars shall be the
                  full responsibility of ECO Fuel Cells and the Licensed

                  Products meeting the specifications of Schedule C and defined
                  as "Commercial Units" in Schedule A are "Commercial Units" for
                  the purposes of this Agreement. The Parties shall consult with
                  one another and mutually agree to review and update Schedules
                  A and C on a quarterly basis. Any changes in Schedules A and C
                  shall be agreed to by both Parties.

         Notwithstanding any other provisions in this Agreement;

                  1.       If ECO Fuel Cells fails to purchase the Fuel Cell
                           Products as required by Schedule A, and those Fuel
                           Cell Products meet Schedule C requirements, H Power
                           shall so notify ECO Fuel Cells in writing; and if not
                           cured within fifteen (15) days, this shall constitute
                           a "breach of any other material term or condition"
                           for the purposes of Article 15.B and H Power shall
                           have the right to terminate this Agreement, following
                           that Article's cure and other provisions.

                  2.       If any of the following events occur, ECO Fuel Cells
                           shall notify H Power in writing, and if not cured
                           within fifteen (15) days, such events shall be
                           considered a "breach of any other material term or
                           condition" for the purposes of Article 15.B, and ECO
                           Fuel Cells shall have the right to terminate this
                           Agreement following that Article's cure and other
                           provisions.

                           a.       If H Power fails to comply with the terms of
                                    Schedules A and/or C, or fails to produce
                                    the first five (5) Commercial Units that
                                    meet Schedule C specifications, by December
                                    31, 2002; or

                           b.       If H Power fails to provide to ECO Fuel
                                    Cells the following "Quarterly Report." By
                                    the fifteenth day after the close of each
                                    calendar quarter during the term of the
                                    Agreement, H Power shall provide to ECO Fuel
                                    Cells a written Quarterly Report on the
                                    status of the design, engineering,

                                    compete with such Fuel Cell Products.

                           c.       This Quarterly Report shall include, but not
                                    be limited to, information related to H
                                    Power's and the Fuel Cell Products'

                                             that compete with Fuel Cell
                                             Products;

                                    v.       developments that may result in any

                  3.       Any material false statement in such Quarterly
                           Reports (except, that as to information on fuel cell
                           products that compete with H Power's, H Power shall
                           only be required to provide information to ECO Fuel
                           Cells to the best of H Power's knowledge and belief).

                                     Page 11
<PAGE>

              The Parties shall consult with one another and mutually agree to
              review and update Schedules A and C on a quarterly basis. July 1,
              2006 shall be called the "Commercial Date" herein.

              Alpha units, Beta units and all other Fuel Cell Products
              previously purchased or to be purchased by ECO Fuel Cells shall be
              credited toward ECO Fuel Cell's purchase obligations under this
              Agreement including Schedule A. Future Beta units shall have the
              minimum specifications and delivery times as agreed to by the
              Parties within twenty (20) days after the execution of this
              Agreement and ECO Fuel Cells shall pay for shipment of them to
              locations selected by ECO Fuel Cells.

         B.       INSPECTION.

                  1.       DURING ALPHA AND BETA FUEL CELL PRODUCT STAGES.
                           During Alpha and Beta Fuel Cell Products stages, such
                           Fuel Cell Products may be shipped to ECO Fuel Cells
                           or the Licensed Members in single units or larger
                           quantities. Purchasers shall have a reasonable
                           opportunity to inspect the Fuel Cell Products for
                           compliance with the standards in Schedule C.
                           Therefore, once a Fuel Cell Product is received, the
                           purchaser will have thirty (30) days in which to
                           inspect the Fuel Cell Product for defects and to
                           notify H Power in writing of such defects.

                  2.       FOLLOWING ALPHA AND BETA FUEL CELL PRODUCTS STAGES.
                           At such time as any individual Fuel Cell Product has
                           passed through its Alpha and Beta stages and is
                           commercialized, the purchaser of such Fuel Cell
                           Product will have seven (7) calendar days from
                           receipt in which to inspect the Fuel Cell Product for
                           any visible defects in the packaging for the units
                           and to notify H Power in writing of such defects.

                  3.       DEFECTS. If the Fuel Cell Product is damaged or
                           otherwise does not pass inspection and H Power has
                           received written notice of such fact within the time
                           periods set forth in Subparagraphs 1. and 2. above,
                           whichever may be applicable, then H Power will have
                           thirty (30) days to cure the problem at its own
                           expense (including shipping, servicing, parts, labor
                           and all other expenses). Notwithstanding the payment
                           requirements as set forth in Paragraph C, immediately
                           hereinbelow, the purchaser need not pay for a Fuel
                           Cell Product that does not pass inspection until the
                           Fuel Cell Product is repaired, replaced or shown to
                           be operable by H Power to the purchaser's reasonable
                           satisfaction. H Power is not responsible for any
                           obvious external shipping damage that has not been
                           reported within the time requirements for valid
                           freight damage claims or other standard commercial
                           freight damage claims practices in effect in the
                           location where the Fuel Cell Product has been
                           delivered.

         C.       PAYMENTS FOR FUEL CELL PRODUCTS.

                  1.       DURING ALPHA AND BETA FUEL CELL PRODUCT STATES.
                           During Alpha and Beta stages, invoices submitted by H
                           Power to ECO Fuel Cells and the Licensed Members for
                           Fuel Cell Products purchased from H Power shall be
                           paid within sixty (60) days of the date of the
                           invoices unless otherwise agreed to by the Parties.
                           Any invoices or portions thereof, not paid within
                           this 60-day period are subject to interest at the
                           rate of 1.5% per month. Should ECO or a Licensed
                           Member fail to pay any amounts due to H Power within
                           the prescribed sixty (60) days, and the failure is
                           not cured within fifteen (15) days after written
                           notice of such failure, H Power may commence
                           collection procedures or judicial action, at law or
                           in equity, to collect such sums, damages, costs,
                           liabilities and expenses, including court costs and
                           reasonable attorney's fees.

                  2.       FOLLOWING ALPHA AND BETA FUEL CELL PRODUCT STAGES.
                           Following the Alpha and Beta Fuel Cell Product
                           stages, and after the Commercial Date, then invoices
                           submitted by H Power to ECO Fuel Cells and the
                           Licensed Members for Fuel Cell Products purchased by
                           them shall be paid within thirty (30) days of the
                           date of the invoices unless otherwise agreed to by
                           the Parties. Any invoices or portions thereof, not
                           paid within this 30-day period are subject to
                           interest at the rate of 1.5% per month. Should ECO
                           Fuel Cells or Licensed Members fail to pay any
                           amounts due to H Power within the prescribed thirty
                           (30) days, and the failure is not cured within
                           fifteen (15) days after written notice of such
                           failure, H Power may commence collection procedures
                           or judicial action, at law or in equity, to collect
                           such sums, damages, costs, liabilities and expenses,
                           including court costs and reasonable attorneys' fees.
                           In the event of two (2) or more consecutive failures
                           to make timely payments, or in the event of three
                           failures in any preceding twelve (12) month period, H

                           marketing, installing and servicing the Fuel Cell
                           Products, unless the trade secrets and confidential
                           information had been previously developed by H Power
                           on its own accord. H Power further represents and
                           warrants that neither H Power nor any company or
                           individual performing services or developing the Fuel
                           Cell Products is under any obligation to assign or
                           give any development work done to any third party. H
                           Power further warrants that it shall have in force
                           valid assignment agreements with any of its employees
                           or subcontractors who may perform services or
                           development of the Fuel Cell Products.

                           By January 1, 2004, H Power shall provide to ECO Fuel
                           Cells an opinion of counsel as to whether the Fuel
                           Cell Products infringe any intellectual property
                           rights. ECO shall receive a copy of such opinion
                           letter. If infringement is suggested, H Power shall
                           cure. Such opinion shall be in sufficient detail that
                           H Power could rely on it to avoid a charge of willful
                           infringement.

                  2.       LICENSE OF REQUIRED INTELLECTUAL PROPERTY. H Power
                           hereby grants to ECO Fuel Cells and the Licensed
                           Members the right to utilize, reproduce and

                           furnished to ECO Fuel Cells and the Licensed Members
                           shall be utilized solely for the purposes of the
                           Distribution Rights granted in this Agreement and not
                           for any other purposes.

                           To the extent that any other intellectual property
                           rights of H Power are needed for ECO Fuel Cells, the
                           Licensed Members, or their subcontractors to market,
                           install and service Fuel Cell Products or carry out
                           the intent of any part of the Agreement, H Power
                           grants to all of them a non-exclusive license in the
                           intellectual property to be used solely for the
                           purposes of this Agreement.

                  3.       ECO FUEL CELLS' TRADEMARK RIGHTS. Subject to the
                           provisions in Article 2.E. hereof, ECO Fuel Cells
                           will have the right to determine and own a name,
                           logo, and other marks ("Marks") under which the Fuel

                           otherwise distributed to Licensed Members and others
                           in the territories to which ECO Fuel Cells has or may
                           obtain Distribution Rights under this Agreement. ECO

                  further warrants that the Fuel Cell Products have been
                  designed by H Power without reliance on ECO, ECO Fuel Cells or
                  Licensed Members and are provided to ECO, ECO Fuel Cells and
                  Licensed Members with appropriate warnings and instructions.

                  H Power expressly warrants that the Fuel Cell Products are
                  merchantable and fit for the particular purpose for which they
                  are designed, and these warranties and H Power's remedies and
                  limitations on damages with respect thereto, will be extended
                  to the end users of the Fuel Cell Products; however this
                  paragraph applies only to the following:

                  1.       ECO and ECO Fuel Cells in their respective companies'
                           capacities (including their successors,
                           representatives, subrogees, and assigns, provided
                           that they are Cooperative Members); and

                  2.       Grandfathered Distribution Agreements (as defined in
                           Article 3.A.1.c. of this Agreement) but only to the
                           extent that Licensed Members retain their exclusive
                           rights thereunder (see Article 3.A.3.c); and

                  3.       First sales by ECO or ECO Fuel Cells but only to
                           their Cooperative Members and not to any resales by

         B.       AUTHORITY. Each Party represents and warrants to the other
                  that it has provided truthful answers to due diligence
                  questions and has all requisite power and authority: 1. to
                  execute, deliver and perform this Agreement and all
                  agreements, documents and instruments executed and delivered
                  by each in connection with it; and that it has no conflicting
                  arrangements or agreements with any other party; 2. to own,
                  lease or operate its property and assets; and 3. to carry on

                  best of its knowledge, there is no outstanding or threatened
                  judgment, litigation or proceeding of any type involving or
                  affecting the transactions described in this Agreement, except
                  as previously disclosed in writing to the other Party on or

                  has fulfilled all of its obligations under the Operating
                  Agreement. Each Party shall comply with all

<PAGE>

                  governmental (whether international, federal, state,
                  municipal, or otherwise) statutes, laws, rules, regulations,
                  ordinances, codes, directives and orders or any such
                  governmental agency, body, or court applicable to it,

                  The Parties shall hold in confidence all provisions of this
                  Agreement and all information provided by either Party to the
                  other in connection with it. The Parties agree that all
                  information related to this Agreement, not otherwise known to
                  the public, is confidential and proprietary and is not to be
                  disclosed to third persons (other than to affiliates,
                  officers, directors, employees and agents of the Parties, each
                  of whom is bound by this provision) without the prior written
                  consent of the other Party, except:

         A.       At the written direction of the other Party;

         B.       To the extent necessary to comply with law (including, without
                  limitation, the disclosure requirements of the U.S. securities
                  laws and any mandatory requirements of the NASDAQ Stock
                  Market, Inc. or NASD) or valid order of a court of competent
                  jurisdiction, in which event the party shall notify the other
                  Party as promptly as practicable (and, if possible, prior to
                  making any disclosure) and shall use its reasonable discretion
                  in determining whether to seek confidential treatment of the
                  information;

         C.       As part of its normal reporting or review procedures to its
                  parent company, Board of Directors, its auditors and its
                  attorneys who agree to be bound by this provision;

         D.       In order to enforce any rights pursuant to this Agreement;

                                     Page 19
<PAGE>

         E.       To obtain appropriate insurance, provided the insurance
                  company agrees in writing to be bound by this provision;

         F.       To obtain financing, provided that any person or entity
                  providing financing agrees in writing to be bound by this
                  provision.

                           All provisions in this Agreement relating to the
                           confidentiality of information shall survive the
                           termination, expiration, cancellation or rescission
                           of this Agreement for a period of five (5) years
                           thereafter.

ARTICLE 14.       ARBITRATION.

                  Except as otherwise provided in Article 4.C. herein, the
                  Parties agree that any and all controversies or claims arising
                  out of or relating to this Agreement, or any alleged breach
                  hereof, shall be resolved by binding arbitration as prescribed
                  herein, if both Parties agree. In that event, the Parties
                  shall mutually agree upon one or more arbitrator(s), not to
                  exceed three, who will conduct the arbitration under the then
                  current rules of the American Arbitration Association ("AAA"),
                  unless otherwise provided herein. The arbitrator(s) will be
                  selected in accordance with AAA procedures from a list of
                  qualified arbitrators maintained by AAA. The arbitration will
                  be conducted in Washington, D.C. and all expedited procedures
                  prescribed under AAA rules will apply. Unless the Parties
                  otherwise agree, the proceedings will be completed within
                  forty-five (45) days of the Parties' receipt of notice of
                  arbitration. Each Party will bear its own costs and attorney's
                  fees and disbursements; and shall share equally the costs of
                  the arbitrators.

ARTICLE 15.       TERMINATION.

         Either Party may terminate this Agreement under the following
circumstances:

         A.       If the other Party hereto shall become bankrupt or insolvent
                  or shall file any debtor relief proceedings, or if there shall
                  be filed in Court against the other Party legal proceedings in
                  bankruptcy or insolvency or reorganization or for the
                  appointment of a receiver or trustee of all or a portion of
                  such other Party's property, or if the other Party makes an
                  assignment for the benefit of creditors or petitions for or
                  enters into an agreement for debtor relief, the other Party
                  immediately shall notify the Party; and if such proceedings
                  are not dismissed within a period of one hundred and fifty
                  (150) days after the institution thereof. Any warranties and
                  guarantees made to the terminating Party shall still survive
                  such termination.

                  H Power Corp. acknowledges and agrees that ECO Fuel Cells has
                  assigned all of its right, title and interest in and to the
                  Agreement to the National Rural Utilities Cooperative Finance
                  Corporation ("CFC"), and that upon the occurrence of an event
                  of default under the Agreement by ECO Fuel Cells, CFC shall
                  have the right, but not the obligation, to exercise and
                  perform all of the rights and obligations of ECO Fuel Cells
                  under the Agreement.

         B.       Except for failure to perform due to force majeure events, in
                  the event that the other Party breaches any other material
                  term or condition of this Agreement and fails to cure such
                  breach within sixty (60) days after receipt of written notice
                  of the breach from the non-breaching Party, the non-breaching
                  Party may terminate this Agreement upon sixty (60) days'
                  advance written notice. In the event that either Party
                  terminates, CFC shall immediately be notified in writing by
                  the terminating Party.

ARTICLE 16.       OTHER.

         A.       NOTICES. All notices or other documents that are required by
                  this Agreement shall be in writing, and shall be personally
                  served upon the Parties entitled thereto or mailed, postage
                  prepaid, by certified or registered mail, or sent via
                  established and reliable courier or overnight service (e.g.,
                  FedEx), or by FAX or other electronic or telecommunications
                  transmission in written form (with telecommunications
                  confirmation of receipt in a clearly legible copy) to the
                  recipient's business addressed to such person at the address
                  specified in this Agreement, or address later specified by
                  written notice by and to the Parties. Any notice or other
                  communication by this method shall be deemed given at the time
                  of sending or certification, except for a notice changing a
                  Party's address, which shall be deemed given at the time of
                  receipt.

         B.       GOVERNING LAW. This Agreement, including any arbitration,
                  shall be governed, construed, and interpreted in accordance
                  with the internal laws of the Commonwealth of Virginia
                  (without giving effect to principles of conflicts of law).

         C.       WAIVER. Any waiver by either Party of a breach of this
                  Agreement shall not operate as a waiver of any other
                  provision. The failure of a Party to insist upon strict
                  adherence to any term of this Agreement shall not be
                  considered a waiver or deprive that Party of the right
                  thereafter to insist on strict adherence to that term or any
                  other term of the Agreement. Any waiver must be in writing.

         D.       SEVERABILITY. Nothing contained in this Agreement shall be
                  construed to require the commission of any act contrary to
                  law, and wherever there is any conflict between any provision
                  of this Agreement and any law, such law shall prevail;
                  provided however, that in the event of any such conflict, the
                  provisions of this Agreement shall be curtailed and limited
                  only to the extent necessary to permit compliance with the
                  minimum legal requirement, and no other provisions shall be
                  affected thereby and all other provisions shall continue in
                  full force and effect.

         E.       TAXES. Each Party is solely and entirely responsible for
                  payment of any and all taxes (including, but not limited to,
                  income, real property, personal property and gross receipts
                  taxes) and contributions to government programs, that are
                  applicable or related to the systems, operations, facilities
                  and/or customers of such Party.

         F.       PARTY'S RELATIONSHIP. Neither Party by this Agreement makes
                  the other Party its legal representative or agent. In
                  addition, neither Party shall assign this Agreement to

                                     Page 21
<PAGE>

                  any other third party, without the other Party's written
                  permission, except that ECO Fuel Cells may assign it to a
                  Cooperative Member.

         G.       FORCE MAJEURE. Any failure of delay of performance shall not
                  be deemed a breach of this Agreement if it results from any
                  acts of God, civil disorders, insurrections, riots, or wars,
                  Year 2000 failures, terrorism, weather, fire, flood, national
                  emergencies declared after the date of this Agreement,
                  government order or regulation, blockade, embargo, strike,
                  work stoppage or similar causes beyond the reasonable control
                  of the Parties.

         H.       INTEGRATION OF AGREEMENT PROVISIONS. All Schedules and any
                  other attachments to this Agreement are incorporated as part
                  of this Agreement. This Agreement supercedes all previous and
                  contemporaneous understandings, commitments and
                  representations, whether oral or written, including the prior
                  Operating Agreement and the MOA, concerning the subject matter
                  hereof. Each Party acknowledges that the other Party has not
                  made any representations other than those provided in this
                  Agreement.

         I.       CUSTOMS DUTIES. H. Power will be responsible for any customs
                  documentation, labeling, processing, duties, charges, and
                  taxes related to the importation of goods by H Power into the
                  U.S. market in connection with this Agreement.

         J.       MODIFICATION. This Agreement may be modified only by a written
                  instrument signed by the Parties.

         K.       NO RIGHTS IN THIRD PARTIES. Except as to Grandfathered
                  Distribution Agreements, nothing contained in this Agreement
                  shall be construed as giving rise to any rights to enforce its
                  provisions to any person or entity not a Party to this
                  Agreement under any legal theory.

         L.       COUNTERPARTS. This Agreement and any document or instrument
                  required or permitted hereunder, may be executed in
                  counterparts, each of which shall be deemed an original and
                  all of which together shall constitute but one and the same
                  instrument.

         -        Included on site initial setting, start-up and commissioning
                  as necessary, byH Power, anywhere in the US during the test
                  program
         -        Outside installation only

o        TECHNICAL ASSISTANCE:
         -        continuous phone assistance (regular hours, working days).
         -        Regularly scheduled visits during test program (frequency to
                  be determined based on initial product performance in the
                  field).

Units are installed parallel to the grid. In the case of failure during the
testing period, the customer will not suffer from a loss of power because power
is then drawn from the grid. A local technician under H Power guidance or a H
Power technician can then start with troubleshooting.

o        TRAINING:
         -        On site,one to two days during commissioning period
         -        One or two days seminar at a central location up to 3
                  times/year

o        MANUALS: Installation, Operation and Maintenance manuals included,
                  RS-232 interfacing and fault diagnostics provided.

Compliance with all Schedule C Standards shall be verified by an independent
third party, if requested by ECO Fuel Cells, LLC. Other Fuel Cell Products shall
be added to this Schedule as their specifications become available.

                                   SCHEDULE C
             RESIDENTIAL COGENERATION UNIT SPECIFICATION DEFINITIONS

NET OUTPUT -            the maximum continuous output of the RCU within the
                        parameters of the system specification (temperature,
                        elevation, etc).

GRID CONNECT -          the ability of the RCU to interact directly with the
                        electric grid.

SYSTEM EFFICIENCY -     the conversion efficiency of fuel energy to electricity
                        at a load point of 4 kW.

COGEN EFFICIENCY -      the percentage of input fuel energy that may be
                        reclaimed as useful heat.

PEAK TOTAL EFFICIENCY - the highest theoretical total efficiency (electric +
                        cogen) that can be obtained by the RCU.

AMBIENT TEMPERATURE -   the temperature of the air surrounding the RCU.

MTBF -                  the average time, over a large sample population, that a
                        unit will operate between unplanned shutdowns. Achieving
                        a particular MTBF is dependent upon adherence to a
                        strict maintenance schedule.

MINOR SERVICE -         the replacement of deionizing cartridges and a
                        preventative maintenance check. By 2006, the homeowner
                        shall replace the deionizer cartridges every 6 months,
                        an operation that will take less than 10 minutes. Each
                        12 months a qualified technician will inspect the unit
                        to perform any necessary preventative maintenance.

MAJOR SERVICE -         the expected replacement interval for components such as
                        a stack, blowers, compressors, etc.

LIFETIME -              the theoretical limit on the life of the unit, generally
                        based on the lifetime of the reformer vessel. This does
                        not correspond to the length of time before the unit
                        becomes obsolete.

INSTALLATION TIME -     the length of time it takes to completely commission a
                        unit, from groundbreaking to system operation.

                                    RECITALS

WHEREAS: On the date hereof, the Parties have entered into the Operating
Agreement to, among other things, further encourage the marketing of H Power's
Fuel Cell Products, to provide the Parties with additional marketing and
distribution opportunities, and to explore other products and services offered
by H Power including new fuel cell products and applications; and

WHEREAS: the Parties desire to mutually encourage the development, marketing and
selling of H Power's Fuel Cell Products to electric Cooperatives and others,
and;

WHEREAS: EFC has specific sales and marketing expertise in Distributed
Generation (DG) equipment and related applications that is transferable to Fuel
Cell Products sales and marketing, and;

WHEREAS: H Power desires to secure EFC's expertise in sales, marketing and other
areas to help enhance the commercialization of its Fuel Cell Products.

NOW, THEREFORE, in consideration of the promises herein and other valuable
consideration, the receipt and sufficiency of which is hereby acknowledged, the
Parties hereby agree as follows:

      1.    FUEL CELL SALES AND MARKETING SUPPORT.

            a.    EFC will work with H Power to identify and create sales
                  opportunities for Fuel Cell Products, including H Power's EPAC
                  series. This will include identification of potential markets
                  and applications, channels of distribution, and similar
                  activities.

            b.    EFC will continue to actively promote the Fuel Cell Power
                  System for residential markets and will participate in
                  evaluation studies and placement of test units to finalize the
                  development of the Cooperative design and to enter other

                  i.    EFC, in collaboration with others, will provide H Power
                        with a report on "typical" electric utility approaches
                        for engineering review of customer requested DG grid
                        interconnection to help H Power better understand
                        interconnection requirements. The report will include
                        the typical utility steps that must be taken to properly
                        account for site-specific concerns and will address the
                        typical technical and procedural requirements of
                        interconnection standards.

                  ii.   EFC shall work with H Power, and both Parties will use
                        reasonable commercial efforts to jointly identify and
                        secure $3.0 million in grants and/or other funds in the
                        eighteen month period following the Effective Date to
                        support the Fuel Cell Product test and development
                        programs, which may include potential funding for
                        related technologies.

                  iii.  EFC shall organize and sponsor a national distributed
                        generation seminar in April 2002 that will include
                        invitations to a broad spectrum of non-Cooperative and
                        Cooperative utilities and customers. H Power will be a
                        featured presenter at the seminar.

                  iv.   EFC shall create new marketing and distribution channels
                        for Fuel Cell Products through the electric Cooperatives
                        and others by encouraging customers to actively seek new
                        applications for Fuel Cell Products that will expand
                        future sales opportunities.

                  v.    EFC shall staff and display H Power products and
                        services at two electric Cooperative industry or related
                        trade shows in 2002 and 2003, one of which shall include
                        the NRECA Annual Meeting in both years. H Power will
                        provide all Fuel Cell equipment for the displays, and
                        EFC shall provide the display space, personnel and
                        display platforms for H Power for a cost not to exceed
                        $50,000 per show.

                  vi.   EFC shall identify, assess and evaluate future and
                        existing Fuel Cell Product markets, fuel cell customer
                        needs, additional product development opportunities and
                        applications and similar items as follows. EFC shall be
                        responsible for developing and managing a structured
                        focus group program consisting of two different
                        participant interview sessions for the purpose of
                        establishing new sales opportunities for $15 million of
                        new revenue from "Other Fuel Cells". EFC shall be
                        responsible for securing participants for the program.

                  vii.  EFC shall develop marketing and promotion materials for
                        H Power, identify marketing issues for H Power and
                        develop market penetration and market share strategies
                        for H Power.

                  viii. EFC's Project Manager for this agreement will work with
                        national Cooperative organizations to secure display and
                        educational opportunities for H Power, and will
                        coordinate any display set ups or material hand-outs

                  requests. Mr. Gibson shall inform both EFC and H Power when
                  potential or real conflicts of activities or scheduling exist,
                  and the Parties shall mutually resolve such conflicts for Mr.
                  Gibson. During the term of this Agreement, H Power shall not
                  solicit any EFC staff for employment.

                  transportation, lodging, meals, and entertainment) and other
                  budgets from time to time to carry out the purposes of this
                  Agreement. In addition to the payments made under Attachment A
                  of this Agreement, any travel to be performed at H Power's

                  Power, except for the travel expenses in conjunction with the
                  planned EFC meetings described in Sections 1.c. iii and 1.c.v.
                  above or as may otherwise be agreed to in writing by the
                  Parties. EFC shall provide satisfactory documentation for such
                  expenses in such detail as H Power may reasonably request.

            3.    LIMITATIONS. IN NO EVENT SHALL THE PARTIES (INCLUDING THEIR
                  OFFICERS, DIRECTORS, EMPLOYEES, AGENTS AND ATTORNEYS) BE
                  LIABLE FOR ANY INDIRECT, SPECIAL, INCIDENTAL OR CONSEQUENTIAL
                  DAMAGES (INCLUDING BUT NOT LIMITED TO LOST PROFITS) IN THE
                  PERFORMANCE OF THEIR DUTIES UNDER THIS AGREEMENT, EVEN IF THEY
                  HAVE NOTICE OF THE POSSIBILTY OF SUCH DAMAGES, EXCEPT FOR (I)
                  ANY PRODUCT LIABILITY, (II) ANY INFRINGEMENT OF INTELLECTUAL

                  HOWEVER, NOTHING HEREIN IS TO LIMIT OR CHANGE THE PROVISIONS
                  OF THE EFC-H POWER OPERATING AGREEMENT (AS AMENDED FROM TIME

            6.    NO MATERIAL ADVERSE CHANGE. Notwithstanding anything contained
                  in this Agreement to the contrary, H Power shall have no
                  obligation to make payments to EFC during the Term hereof, if
                  there has been a "Material Adverse Change." For the purposes
                  of this Agreement, a Material Adverse Change shall only be
                  defined as a material violation of Sections 2, 3, 4, or 5 of
                  the Memorandum of Agreement.

            7.    FAILURE TO COMPLY. Notwithstanding anything contained in this
                  Agreement to the contrary, upon ECO's and/or EFC's breach of
                  any of the Affirmative or Negative Covenants set forth in the
                  Memorandum of Agreement, H Power shall have the unilateral
                  right to suspend payment of any monies due to EFC hereunder
                  (including those set forth on Attachment A hereto) until such
                  time that ECO and/or EFC cures such breach to H Power's
                  satisfaction.

            8.    TERM. This Agreement shall terminate upon: i) the completion
                  of EFC's and ECO's duties referred to herein; or ii) the
                  written agreement of the Parties.

            9.    DISPUTES. The Parties agree that any and all controversies or
                  claims arising out of or relating to this Agreement, or any
                  alleged breach hereof, shall be resolved by binding
                  arbitration as prescribed herein, upon 30 days' written notice
                  to the other Party. In that event, the Parties each Party
                  shall select one (1) arbitrator and those shall select a
                  third. The three (3) arbitrators will conduct the arbitration
                  under the then current rules of the American Arbitration
                  Association ("AAA"), unless otherwise provided herein. The
                  arbitrator(s) will be selected in accordance with AAA
                  procedures from a list of qualified arbitrators maintained by
                  AAA. The arbitration will be conducted in Washington, D.C. and
                  all expedited procedures prescribed under AAA rules will
                  apply. Unless the Parties otherwise agree, the proceedings
                  will be completed within forty-five (45) days of the Parties'
                  receipt of notice of arbitration. Each Party will bear its own
                  costs and attorney's fees.

            10.   MUTUAL COOPERATION. The Parties agree to take such other
                  actions and execute such other documents as shall be necessary
                  to carry out the provisions of this Agreement.

            11.   ENTIRE AGREEMENT. With the exception of the Operating
                  Agreement and the Memorandum of Agreement, this Agreement
                  (including any Schedules and Exhibits attached hereto)
                  constitutes the entire agreement among the Parties with
                  respect to the subject matter hereof and supercedes all prior
                  and contemporaneous agreements and undertakings, written or
                  oral, of any nature whatsoever of the Parties hereto with
                  respect to the subject matter hereof.
