Effective Date) by and between FCE and MTU.

                                     WHEREAS

FCE and MTU presently are parties to the Balance of Plant  Cross-License of July
16,1998 (the BOP CROSS-LICENSE), and the License Agreement of September 29, 1989
(the  PREVIOUS  LICENSE)  which is  superseded  by this  Agreement  (the  "CELL
LICENSE").

FCE has developed  Carbonate  Fuel Cell  technologies  known as the "Direct Fuel
Cell  (TM)"  (DFC(TM))  including  fuel cell  stacks,  components  thereto,  and
manufacturing methods, processes and procedures thereto.

FCE intends to continue  development  of the DFC(TM) Know How (as defined below)
and provide the results to MTU in accordance with Article V below.

FCE  has  established  a  fuel  cell   manufacturing   facility  in  Torrington,
Connecticut, USA which is capable of providing reasonable DFC(TM) cell and stack
production requirements for both FCE and MTU.

FCE and MTU  retain  the  right  to  independently  pursue  the  development  of
Carbonate Fuel Cell  technologies as each Party sees fit at its sole discretion.
Notwithstanding  this  right,  FCE and MTU shall  endeavor  to develop  the best
Carbonate Fuel Cell  technology  with as much global  product  commonality as is
reasonable.

MTU plans to develop the [***] CELL (as defined below) and may provide the [***]
CELL Know How to FCE in a license to be negotiated.

MTU's sales or licenses of carbonate fuel cell power plants using the [***] CELL
are  subject to and not exempt  from the  royalties  owed to FCE under this Cell
License  Agreement so long as the [***] CELL uses  DFC(TM) Know How.  [***] CELL
Know How developed by MTU is not subject to the Cell License  Agreement  even if
one or more [***] CELL elements are developed in parallel by FCE.

MTU has,  under the Previous  License,  developed  Existing  Carbonate Fuel Cell
improvements (EXISTING IMPROVEMENTS) as defined below, which have or may be used
by FCE hereunder.

FCE and MTU agree to work in the spirit of a fair partnership between equals and
each Party  acknowledges the intellectual  property  contributions and rights of
the other Party.

FCE  warrants,  represents  and agrees that it has the capacity and authority to
grant the licenses hereunder and to be bound by the terms of this CELL LICENSE.

MTU  warrants,  represents  and agrees that it has the capacity and authority to
grant the licenses hereunder and to be bound by the terms of this CELL LICENSE.

The  substance of those terms of the  Previous  License  which were  intended to
survive the termination of the Previous License have been incorporated herein.

     to MTU by FCE shall be equal to FCE's direct and indirect costs  determined
     in accordance with the Federal Acquisition  Regulation Part 31 plus a [***]
     ([***] %) fee. At the  beginning  of each  fiscal  year FCE will  establish
     Overhead and G&A rates as part of its budgeting process.  MTU will agree in
     advance as to the volume and timing of  production  which has been included
     for  their  orders  in the FCE  budget . The  budgeted  rates  will then be
     "fixed" for  purposes of all billing to MTU for DFC  components  and stacks
     purchased  during that fiscal year.  FCE will be at risk for any  deviation
     from these fixed rates.  If MTU modifies the volume and/or the schedule for

     shall be adjusted by the increase in the United States Consumer Price Index
     (CPI) from September,  1999 to the date of each sale, based on the ratio of
     the CPI as of September, 1999 compared to the CPI at the month of the sale.
     This adjustment shall be subject to a limit of increase per year of 7%.

5.   All payment required under this Article IV shall be made within thirty (30)
     days of the close of the calendar quarter of each year of this CELL LICENSE
     Agreement.

Article IX - Arbitration, Governing Law

1.   Should any  dispute,  controversy  or claim  arise  between  FCE and MTU in
     connection with,  relating to or rising out of this CELL LICENSE Agreement,
     efforts to resolve such an issue shall be made by the  respective  Parties.
     If a resolution  is not  achieved,  either Party may refer the issue to the
     executive  officers of FCE and MTU, who shall  endeavor to reach a mutually
     acceptable resolution.

2.   In the event an  acceptable  resolution  is not reached  within thirty (30)
     days of the  request  to the  officers  made per  Article IX Section 1, the
     Parties shall submit the dispute to nonbinding  mediation  with a certified
     mediator to be mutually  agreed upon by the Parties.  Each Party shall bear
     its own expenses (including attorneys' fees) for such mediation proceeding.

3.   In the event an  acceptable  resolution  is not reached  within thirty (30)
     days of the initiation of mediation  proceedings  per Article IX Section 2,
     then the issue  shall be  submitted  to  arbitration  before  the  American
     Arbitration  Association  in  accordance  with the  Rules  of the  American
     Arbitration Association then in effect. The arbitration shall take place in
     the

     the  arbitration  shall  be that  of the  State  of New  York,  U.S.A.  The
     arbitration  award shall be final and binding upon the parties.  Such award
     may be  confirmed  in any court  having  jurisdiction  and reduced to final
     judgment.

Article X - Infringements

1.   In the event of an  infringement  by a third party against any claim of any
     DFC(TM)  patent  licensed  hereunder,  or  in  the  event  of  a  claim  of
     infringement  against either Party for use of any such patent,  the Parties
     shall each have the right to undertake  appropriate legal action or defense
     in their own name,  or if so  required  by law,  in the name of the  patent
     owner. The Party to such action shall have the full cooperation and support
     of the other Party,  including for example,  access to records and employee
     testimony as needed and shall provide full  communication  of the status of
     such action.

2.   Each Party hereunder shall be responsible for its own legal and other costs
     in case of an infringement suit brought by a Party hereunder.

3.   The Party  owning  the  Patent  against  which a claim of  infringement  is
     brought shall always be responsible for legal costs of defending  against a
     claim  of  infringement  (i.e.  FCE  shall be  responsible  for the cost of
     defending  an  infringement  suit  against  MTU  regarding  MTU's use of an
     FCE-owned  European  patent,  and MTU shall be responsible  for the cost of
     defending  an  infringement  suit  against  FCE  regarding  FCE's use of an
     MTU-owned U.S. patent).

4.   In the event of an award of damages  resulting from any  infringement  suit
     brought by FCE or MTU, the Parties shall mutually agree on division of such
     award.

5.   Neither Party may consent to settlement of any  infringement  claim against
     itself if such  settlement  would result in  elimination or decrease of any
     patent  rights  owned by the other  party  without the consent of the other
     Party.

6.   In the  event a  patent  infringement  suit  results  in a  final  judicial
     decision or settlement  resulting in damages  charged  against either Party
     for use of the other Party's  patents,  the Patent owner shall be obligated
     to share in such  damages at 50% of the total  damage award up to a maximum
     of $250,000 in total.

7.   The provisions of this Article X shall survive the termination of this CELL
     LICENSE  Agreement  for  fifteen  years  or  until  expiration  of the last
     surviving patent licensed hereunder, whichever is later.

Article XI - Filing Of Patent Applications

     to U.S. patent  applications filed by FCE during the term of this Agreement
     and  included  in  the  Patent  Rights;   provided,   however,   that  such

     Article XI ("Prosecution  Costs") up to and including the first Twenty Five
     Thousand United States Dollars  ($25,000.00).  All Maintenance  Costs which
     exceed Ten Thousand United States Dollars  ($10,000.00) and all Prosecution

     in any year of this Agreement shall be shared equally by FCE and MTU.

     undertake  contracts related to DFC(TM) Products and Know How with the U.S.

     contrary,  either Party shall have the right to assign this  Agreement  and
     its  rights  and  obligations  hereunder  to an  Affiliate  to said  Party,
     provided,  however, that, prior to any such assignment,  (i) said Affiliate
     delivers to the other Party a  counterpart  of this  Agreement  executed by
     said Affiliate  including a statement that the Affiliate agrees to be bound
     by and  perform  the  obligations  of the  assigning  Party  and  (ii)  the
     assigning Party delivers to the other Party a written  agreement  providing
     that the assigning Party shall remain  primarily liable for the performance
     of the assignee's  obligations under this Agreement and a guarantee of such
     Affiliate's  performance  satisfactory  in all respects to the other Party.
     The provisions of this Section 4 shall continue after natural expiration or
     termination of this  Agreement  with respect to all rights and  obligations
     which continue after or survive such expiration or termination.

Article XIII -  Substitution  of Provisions,  Order of  Precedence,  Survival of
Provisions

1.   If any provision of this CELL LICENSE  Agreement  should be or become fully
     or partly  invalid or  unenforceable  for any reason  whatsoever  or should
     violate any applicable law, this CELL LICENSE Agreement is to be considered
     divisible as to such  provision and such  provision is to be deemed deleted
     from this CELL LICENSE  Agreement,  and the  remainder of this CELL LICENSE
     Agreement shall be valid and binding as if such provision were not included
     herein.  There shall be  substituted  for any such  provision  deemed to be
     deleted a suitable  provision which, as far as is legally  possible,  comes



     nearest to what the parties desired or would have desired  according to the
     sense and purpose of this CELL LICENSE  Agreement,  had they considered the
     point when concluding this CELL LICENSE Agreement.

2.   In the event of any conflict  between the  provisions  of this CELL LICENSE
     and the Previous  License the provisions of this CELL LICENSE shall prevail
     over the Previous License.

3.   The provisions listed below shall survive termination of this CELL LICENSE:
     Export   Control   provisions   set  forth  in   Article   II   Section  4;
     Confidentiality  provisions  set forth in  Article V Section 2 and  Article

any specific research or development for the other Party.

Article XV - Publicity Releases and Disclosure of Agreement

1.   Neither Party hereto shall issue or release to any third party  information
     in any way related to the execution, performance or terms and conditions of
     this  Agreement  (except  as  specifically   allowed  and/or   contemplated
     hereunder)  without the prior  written  consent of the other  party,  which
     consent shall not be unreasonably  withheld,  except for disclosures  which
     are required to be made by applicable laws or rules and regulations.

2.   If as part of a grant  application or other process to receive funding from
     a government or governmental agency including the European Union and any of
     its agencies (a "Governmental Authority"), it is necessary for either Party
     or its sublicensees to disclose the other Party's Know-how,  then the Party
     desiring  to make  such  disclosure  will  submit  to the  other  Party the
     required  disclosure  prior  to such  party  incurring  the  obligation  to
     disclose the same to the respective Governmental Authority. If either Party
     believes that such a disclosure  will de detrimental to its interest,  then
     such  information  may only be  disclosed  if such  Governmental  Authority
     agrees to keep such  information  confidential  substantially in accordance
     with the confidentiality provisions contained in Article V Section 2.
