consent export, cause to be exported or facilitate the export of Ni-Zn batteries
out of either the Exclusive  Licensed  Territory or the  Non-Exclusive  Licensed
Territory,  nor sell,  lease or transfer  Ni-Zn  batteries to third  parties for

                               III PAYMENTS

      3.1 Transfer  Payment.  The total payment (the "Transfer  Payment") (which
does not include royalties) for the transfer of the Licensed Technology is three
million  U.S.  dollars  (US$3,000,000).  This amount shall be paid to ERC by the
Joint Venture  within sixty (60) days of the Effective Date of the Joint Venture
Contract.

      3.2 Payment  Procedures.  All  payments  made  pursuant  to this  Contract
including  all royalty  payments due under Part V hereof,  shall be made by wire
transfer to an account  designated by ERC or Xiamen net of any applicable taxes,
withholdings,  duties owed by the Joint Venture or ERC or Xiamen (excluding,  in
the case of ERC or Xiamen,  only income or corporate excise taxes imposed by the
U.S.  or  P.R.China   and  its  states  and   instrumentalities   respectively).
Accordingly, whatever payment is due hereunder the Joint Venture shall make such
additional  payments as are  necessary  to ensure that the net amounts  actually
received  by ERC or  Xiamen  will not be less  that the  amounts  it would  have
received if such taxes and the like were not  required to be paid.  All payments
hereunder shall be made in U.S.  dollars or Chinese currency by wire transfer to
a bank account designated by ERC or Xiamen  respectively.  Where it is necessary
to convert  Chinese  currency into U. S. dollars for the purpose of  calculating
and paying  royalties under Part V of this Contract,  the exchange rate shall be
determined by reference to the average of the daily exchange rates  published by
the People's Bank of China on the day the conversion is made.

      3.3  Reinvestment.  ERC will  reinvest the Transfer  Payment of $3 million
received  under Section 3.1 hereof or more to purchase a 51% equity  interest in
this Joint  Venture  within 90 days of the  Effective  Date of the Joint Venture
Contract.

                          IV TECHNOLOGY TRANSFER

      4.1 The Licensed  Technology  will be transferred to the Joint Venture for
use in the Field pursuant to this Contract upon receipt of the Transfer  Payment
made in accordance with Section 3.2 hereof.

      4.2 Such transfer  shall take place within six (6) months of the Effective
Date of the Joint  Venture  Contract  and at ERC's  Facility in  Danbury,  CT to
persons designated by the Joint Venture.  ERC will provide reasonable support to
transfer  Licensed  Technology  at no cost to the Joint Venture in order for the
Joint Venture to duplicate the Ni-Zn battery  performance  set forth in Appendix
B. Persons  designated  by the Joint  Venture to accept the  transfer  will have
reasonable access to all personnel and equipment at ERC's Facility to facilitate
the transfer.








                              V.   ROYALTIES

       5.1 Royalty Payments. As additional consideration for the license granted
herein, the Joint Venture shall pay to ERC a royalty of ________ percent (____%)
on Net Sales of Ni-Zn  batteries  sold,  leased or  transferred in the Exclusive
Licensed  Territory  and  ________  percent  (____%)  on such  Net  Sales in the
Non-Exclusive  Territory.  The contract  establishing  the Joint  Venture  shall
provide that the Joint  Venture  shall  distribute  to Xiamen from its Net Sales
income an amount  equivalent  to a royalty of  ________  percent  (____%) on Net
Sales of Ni-Zn batteries sold,  leased or transferred in the Exclusive  Licensed
Territory and ________  percent  (____%) on such Net Sales in the  Non-Exclusive
Licensed  Territory The  obligation  to make royalty  payments  hereunder  shall
commence with the first product  sales,  leases or transfers of Ni-Zn  batteries
manufactured by the Joint Venture,  its agents or affiliates and royalties shall
thereafter  by payable  semi-annually  thirty  (30) days after the close of each
June 30 and  December 31 of each year in which  products  subject to royalty are
sold,  leased or transferred.  All payments shall be made in accordance with the
payment provisions in Sections 3.2 hereof.

       5.2 Records and Reports. The Joint Venture shall keep accurate,  detailed
records and books of account containing all information  reasonably  required to
compute  and  verify  royalties  due to ERC  and  Xiamen  under  this  Contract,
including information  concerning products manufactured and assembled and sales,
leases and other transfers by the Joint Venture,  its agents and its affiliates.
Such books and records shall be maintained for at least five (5) years after the
year to which  they  relate.  When  rendering  payment of  royalties,  the Joint
Venture  shall  provide  ERC and Xiamen  with a written  accounting  showing the
calculation  of the  royalty,  the number of  products  to which the  royalty is
applicable and the Net Selling Price. At its expense,  ERC or Xiamen may, by its
designated  independent  public  accountants,  audit  once  annually  all  Joint
Venture,  royalty  records  and books kept by the Joint  Venture to confirm  the
accuracy of the Joint Venture's calculations of the Net Selling Price, Net Sales
and royalties due; provided  however,  that in the event such an audit discloses
that the actual royalty amount due under this Contract for the applicable period
is more than five percent (5%) greater than the royalty  amount  reported by the
Joint Venture for such period,  the Joint Venture shall pay the reasonable costs
of such audit incurred by ERC or Xiamen.

reason before the end of its Term the Joint  Venture will  promptly  deliver and
return to ERC the  Licensed  Technology  and all  technical  information  it has
received from ERC or derived from the Licensed Technology.  Thereupon, the Joint
Venture shall not use the Licensed Technology for any purpose and ERC shall have
the right by any legal means to  determine  that the License  Technology  is not
being used.

       6.4  Liability and  Indemnity.  ERC makes no  warranties  concerning  any
products developed or manufactured by the Joint Venture. The Joint Venture shall
