Commercial Units and provide Services within the Territory; and (b) maintain, at
its own expense, such office space and facilities, and hire and train such
personnel as DISTRIBUTOR may deem necessary to carry out its obligations under
this Agreement. DISTRIBUTOR will use its best efforts to market and sell
Products and Pre-Commercial Units in the manner that its Affiliates market and
sell similar products, and to provide Services to ensure a level of customer
service consistent with that provided for other GE-branded products, taking into
consideration the lower sales volumes of Products and Pre-Commercial Units.
Within 60 days after the effective date of this Agreement, SUPPLIER and
DISTRIBUTOR will mutually agree to a marketing and Services development schedule
for the period ending December 31, 2000, which will include milestones and
objective measures of progress towards the January 1, 2001, Product release.
SUPPLIER and DISTRIBUTOR will meet not less than quarterly for the purpose of
evaluating DISTRIBUTOR's progress against the development schedule.

     5.2  Purchase Volume Goal. During the Term of this Agreement, DISTRIBUTOR
          --------------------
shall use its best efforts to achieve minimum Global Sales Commitments and Major
Market Sales Commitments as defined and specified in Schedule D. DISTRIBUTOR
                                                     ----------
shall provide SUPPLIER with a 12-month rolling forecast of monthly purchases in
accordance with Schedule D. In the event that DISTRIBUTOR fails to achieve the
                ----------
minimum purchase volume goals set forth in Schedule D, SUPPLIER may appoint
                                           -----------
additional distributors and/or terminate this Agreement under the provisions
specified in Schedule D.  In the event that SUPPLIER appoints any additional

distributors pursuant to the preceding sentence, DISTRIBUTOR may terminate this
Agreement upon 120 days written notice.

     5.3  Expenses. Except as otherwise provided in this Agreement, DISTRIBUTOR

          ------------------------
Product applications, customer demand) related to the sale and use of Products

"DISTRIBUTOR Intelligence").

     5.5  Pre-Commercial Units. DISTRIBUTOR shall purchase, on a take or pay
          --------------------
basis, 485 Pre-Commercial Units, as specified in Schedule B, for delivery by
                                                 ----------
December 31, 2000, at a purchase price of $21,134 per unit, with no more than
250 units to be delivered in any one quarter. One-fourth of the purchase price
shall be paid to SUPPLIER as a deposit six months prior to delivery but no
earlier than January 1, 2000, and the balance of the purchase price shall be
paid on delivery. To the extent



DISTRIBUTOR elects to purchase units available prior to the Pre-Commercial
Units, DISTRIBUTOR's purchases will be credited against its take-or-pay
commitment on a dollar-for-dollar basis (e.g., if DISTRIBUTOR purchases
$1,000,000 of Test & Evaluation Units available in 1999, DISTRIBUTOR'S take-or-
pay commitment on the Pre-Commercial Units will be reduced by $1,000,000).
DISTRIBUTOR will make reasonable efforts to have its Customers for Pre-
Commercial Units perform certain testing as prescribed by SUPPLIER, provide
SUPPLIER with all data generated by such testing, and provide SUPPLIER with
reasonable on-site access to the Pre-Commercial Units.

     5.6  Assistance. DISTRIBUTOR shall, if required by SUPPLIER, provide
          ----------
SUPPLIER with reasonable access to and assistance of its sales and marketing
personnel. Such assistance shall be without charge to SUPPLIER except as may be
otherwise mutually agreed.

     5.7  Regulatory Approvals. In conjunction with SUPPLIER's obligations in
          --------------------
Section 6.6, DISTRIBUTOR shall be responsible for the administration and field
work necessary to obtain any regulatory approvals for DISTRIBUTOR to conduct its
operations in the Territory. DISTRIBUTOR shall provide assistance to SUPPLIER in
order to assist SUPPLIER in complying with registration requirements in the
Territory, obtain such other approvals from governmental authorities of the
Territory as may be necessary to comply with any and all governmental laws,
regulations, and orders that may be applicable to DISTRIBUTOR by reason of the
execution of this Agreement, and assist SUPPLIER in taking those actions
necessary for DISTRIBUTOR to be registered as SUPPLIER's independent distributor
with any governmental authority. Without limiting the foregoing, DISTRIBUTOR
shall furnish SUPPLIER with such documentation as SUPPLIER may request to
confirm DISTRIBUTOR's compliance with this Section, and DISTRIBUTOR agrees that
it shall not engage in any course of conduct that would cause SUPPLIER to be in
violation of the laws of any jurisdiction within the Territory. DISTRIBUTOR
shall comply fully with, and shall be solely responsible for, all safety
standards, health code requirements and regulations, specifications, and other
requirements imposed by law, regulation, or order in the Territory and
applicable to the marketing and sale of the Products and Pre-Commercial Units,
and to the provision of Services provided by DISTRIBUTOR.

                             --------
SUPPLIER of any of its obligations hereunder.

     6.3  Assistance. SUPPLIER shall, if required by DISTRIBUTOR, provide

any additional capacity required to fill any of DISTRIBUTOR'S firm purchase
orders; provided that DISTRIBUTOR stays on schedule, as determined in good faith
by SUPPLIER, in developing the infrastructure necessary to market, sell, and
provide Services to such volume of Products; and provided further that SUPPLIER
will not be obligated to increase Product supply by more than 100% between any
two quarters, and, in any event, SUPPLIER will not be obligated to increase
Product supply beyond the Global Sales Commitments.

          (b)  SUPPLIER will use best efforts to produce 485 Pre-Commercial

Research and Development Department of General Electric Company of the
development and testing of Products, Pre-Commercial Units, and Test & Evaluation
Units, with specific projects to be specified by SUPPLIER in such separate
agreement. The failure of SUPPLIER to enter into such agreement shall constitute
cause for termination of this Agreement pursuant to Section 4.2(a), without
regard to materiality considerations. SUPPLIER will use reasonable efforts to
enter into such agreement within 90 days following the execution date of this
Agreement.

          -----------------------------------
SUPPLIER may have under Article VIII hereof, SUPPLIER shall take all actions

Intellectual Property Rights relating to the Products and Pre-Commercial Units.
Without limiting the generality of the foregoing, SUPPLIER shall defend and
indemnify DISTRIBUTOR against any suit, claim, or proceeding brought against
DISTRIBUTOR that is based on a claim that any trademark owned or used by
SUPPLIER directly in connection with any Product, Pre-Commercial Unit, or any
part thereof (except for DISTRIBUTOR's Trademark), as such trademark was affixed
to such Product, Pre-Commercial Unit, or part thereof in accordance with Section
7.2, infringes any intellectual property right of any third party in any country
or other jurisdiction in the Territory, if notified promptly in writing and
given authority, information, and assistance (at SUPPLIER's expense) for the
defense of same, and provided that such infringement did not arise as a result
of DISTRIBUTOR's unauthorized use of such trademark.  SUPPLIER shall pay all
damages and costs awarded with respect to any suit, claim, or proceeding for
which SUPPLIER is required to provide indemnification pursuant to this Section

and indemnify DISTRIBUTOR against any suit, claim or proceeding brought against
DISTRIBUTOR that is based on a claim that any Product or Pre-Commercial Unit, or
any part thereof, furnished under this Agreement, as well as any device or
process necessarily resulting from the use thereof, constitutes an infringement
of any patent of the United States (or any other country or other jurisdiction
in the Territory), if notified promptly in writing and given authority,
information, and assistance (at SUPPLIER's expense) for the defense of same, and
provided that such infringement did not arise as a result of (a) DISTRIBUTOR's
developments, misuse, or modifications that were not approved by SUPPLIER, or
(b) DISTRIBUTOR's combination, operation, or use with devices, data, equipment,
systems, programs, or products not furnished by SUPPLIER, contemplated by the
specifications in Schedule B, or approved by SUPPLIER, SUPPLIER shall pay all
                  ----------
damages and costs awarded with respect to any suit, claim, or proceeding for
which SUPPLIER is required to provide indemnification pursuant to this Section
7.5.  In the event a claim is made or appears likely to be made that any Product
or Pre-Commercial Unit, or any part thereof, furnished under this Agreement, as
well as any device or process necessarily resulting from the use thereof,
infringes upon a third party's patent, SUPPLIER shall, at its own expense and at
its option, and in

                                      -13-


addition to all other rights or remedies which the DISTRIBUTOR may have pursuant
to this Agreement, (a) procure for DISTRIBUTOR the right to continue using said
Product, Pre-Commercial Unit, part, device, or process; (b) replace same with a
non-infringing equivalent; or (c) remove said Product, Pre-Commercial Unit,

                                  ----------

                     TERMS AND CONDITIONS OF PURCHASE/SALE



1.  ACCEPTANCE OF TERMS AND CONDITIONS.  (a) DISTRIBUTOR and SUPPLIER agree to
be bound by and to comply with all the terms and conditions in and referred to
in this Schedule B, as well as those appearing elsewhere in the Agreement (to
        ----------
which the section references contained herein apply), in any supplements hereto
and in all specifications and other documents referred to herein. (b) An order
by DISTRIBUTOR or the acceptance of an order by SUPPLIER does not constitute an
acceptance by the DISTRIBUTOR or SUPPLIER of any offer to sell, any quotation,
or any proposal, other than under the terms and conditions contained in this
Agreement. ANY PURCHASE ORDER, ATTEMPTED ACKNOWLEDGMENT OF AN ORDER, OR ANY
DOCUMENT CONNECTED THEREWITH, CONTAINING TERMS AND CONDITIONS INCONSISTENT WITH
OR IN ADDITION TO THE TERMS AND CONDITIONS IN THIS SCHEDULE B IS NOT BINDING
                                                   ----------
UPON DISTRIBUTOR OR SUPPLIER UNLESS SPECIFICALLY ACCEPTED BY DISTRIBUTOR AND
SUPPLIER IN WRITING.

2.  PRICES AND PAYMENTS.  SUPPLIER's prices are firm, are as specified in
Schedule C and shall not be subject to change, except as provided in this
- ----------
Agreement and Schedule C. SUPPLIER's total price is FOB SUPPLIER's designated,
              ----------
continental U.S. manufacturing facility, unless otherwise agreed in writing by
SUPPLIER and DISTRIBUTOR. All prices are exclusive of any applicable federal,
state, or local sales, use, excise, or other similar taxes, provided, however,
that any such taxes to which SUPPLIER becomes subject as a result of
manufacturing, having manufactured, or procuring Products or Pre-Commercial
Units, shall be borne by SUPPLIER. No extra charges of any kind will be allowed
unless specifically agreed to in writing by DISTRIBUTOR. Unless otherwise agreed
between SUPPLIER and DISTRIBUTOR, payments shall become due 45 days from receipt
of invoice. In the event of delay in payment, DISTRIBUTOR will pay SUPPLIER a
late fee equal to the lesser of 1.5%, or the maximum rate allowable by law, of
any unpaid balance per month of delay or the maximum rate allowable by law.
DISTRIBUTOR must make payment when due, without offset, deduction, or
counterclaim, regardless of any claim by DISTRIBUTOR.

3.  DELIVERY AND PASSAGE OF TITLE.  Time is of the essence of all purchase
orders, except that delivery dates will be framed in terms of calendar months
and orders will not be deemed late until after the end of such calendar month.
If SUPPLIER fails to deliver the Products or Pre-Commercial Units or to complete
any Services furnished hereunder, then DISTRIBUTOR shall be entitled, in
addition to the remedies available elsewhere under the Agreement, to assess an
amount, as liquidated damages for delay, equal to 1% of the total dollar value
of DISTRIBUTOR's order for the first month of delay and 2% of the total dollar
value of DISTRIBUTOR's order per subsequent month of delay; provided, (a) that
such remedy will be capped at 6%, (b) if the order is more than three months
late, then DISTRIBUTOR may cancel the order, and (c) such liquidated damages
will only be available to DISTRIBUTOR for those orders to the extent that
DISTRIBUTOR has provided such remedy to its Customer. SUPPLIER agrees that such
amounts are a reasonable pre-estimate of the damages which DISTRIBUTOR may
suffer as a result of such delay, and are to be assessed as liquidated damages
and not as a penalty. Where such liquidated damages are available to
DISTRIBUTOR, they shall be DISTRIBUTOR's only remedy for SUPPLIER's failure to
make timely delivery, other than the remedies for non-performance expressly set
forth in this Agreement.

Products or Pre-Commercial Units which will be shipped from within the United
States for delivery within the United States shall be delivered FOB SUPPLIER's
designated, continental U.S. manufacturing facility, unless otherwise agreed in
writing by SUPPLIER and DISTRIBUTOR. Products or Pre-Commercial Units delivered
to DISTRIBUTOR in advance of schedule may be returned to SUPPLIER at SUPPLIER's
expense. Title shall pass to DISTRIBUTOR upon delivery to DISTRIBUTOR FOB
SUPPLIER's designated, continental U.S. manufacturing facility.

4.  CHANGES.  The DISTRIBUTOR may at any time, in writing, request changes
within the general scope of a purchase order in (a) specifications, where the
Products or Pre-Commercial Units to be furnished are to be specifically
manufactured in accordance therewith, (b) method of shipment or packing, or (c)
place and time of delivery. Any such change shall be authorized only by an
amendment executed by SUPPLIER and DISTRIBUTOR, with such amendment to specify
any additional expense, to be borne by DISTRIBUTOR.

5.  INSPECTION.  (a) All Products and Pre-Commercial Units shall be subject to
inspection and test by DISTRIBUTOR at reasonable times and places upon
reasonable notice, including the place of manufacture (which SUPPLIER shall use
reasonable efforts to arrange, including providing for such access in SUPPLIER's
purchase orders to the manufacturer); (b) If any inspection or test is made on
the premises of SUPPLIER, then SUPPLIER, without additional charge, shall
provide reasonable facilities and assistance for the safety and convenience of
the inspectors  in the performance of their duties, provided that the inspectors
must execute SUPPLIER's standard confidentiality agreement, must abide by such
facility's rules and regulations, and must be covered by insurance for
occurrences other than due to SUPPLIER's negligence or willful misconduct; and
(c) SUPPLIER shall provide and maintain a program, to the mutual satisfaction of
SUPPLIER and DISTRIBUTOR, in order to create ongoing product design,
manufacturing, testing, inspection, and other safety and quality-related
processes that are adequate to assure the safety and reliability of SUPPLIER's
Products and Pre-Commercial Units (the "Product Quality and Safety Assurance
Program"). Records of all inspection work by SUPPLIER shall be kept complete and
available to DISTRIBUTOR during the performance of a purchase order and for
three (3) years from the date of such inspection. SUPPLIER will allow
representatives of DISTRIBUTOR access to the facilities involved in performing
an order for purposes of reviewing the status and progress of production.

6.  REJECTION.  If any of the Products, Pre-Commercial Units or Services (to the
extent that SUPPLIER is providing Services) ordered are found by DISTRIBUTOR
within 30 days of delivery to be defective, or otherwise not in conformity with
the requirements of the order, including any applicable specifications,
SUPPLIER, at its option and sole discretion may: (a) instruct DISTRIBUTOR to
return such goods at SUPPLIER's expense; (b) request that DISTRIBUTOR, with
DISTRIBUTOR's written approval, take such actions as may be required to cure all
defects and/or bring the Products or Pre-Commercial Units into conformity with
all requirements, in which event any reasonable costs and expenses thereby
incurred by DISTRIBUTOR, including material and handling charges, will be at
SUPPLIER's expense; and (c) re-perform, at SUPPLIER's own expense, any defective
portion of the Services performed, to the extent that SUPPLIER is performing
Services. DISTRIBUTOR must notify SUPPLIER in writing of such defect or
non-conformity within 30 days after delivery of the Products or Pre-Commercial
Units or performance of Services, if applicable, or DISTRIBUTOR's rights under
this Section 6 shall be waived. The remedies in this Section 6 shall be
DISTRIBUTOR's exclusive remedies under this Section 6.

7.  WARRANTIES.  (a) SUPPLIER will convey clear title to all Products and
Pre-Commercial Units to DISTRIBUTOR as provided hereunder; (b) SUPPLIER warrants
and represents that all Products, Pre-Commercial Units and Services (to the
extent that SUPPLIER provides Services) sold hereunder or pursuant hereto will
be free from all material defects in workmanship and material, and that the
Products, Pre-Commercial Units and Services (to the extent that SUPPLIER
provides Services) are provided in strict accordance with the specifications set
forth in Schedule B, and (c) Except as provided by this Agreement, any attempt
         ----------
by SUPPLIER to limit, disclaim, or restrict any such warranties or any remedies
of DISTRIBUTOR, except as limited by this Agreement, by acknowledgment or
otherwise, in accepting or performing an order, shall be null, void and
ineffective without DISTRIBUTOR's written consent. For Products purchased under
this Agreement, the foregoing warranties shall apply for a period of the lesser
of twelve (12) months from the date of installation or eighteen (18) months from
delivery to DISTRIBUTOR. For Pre-Commercial Units purchased under this
Agreement, the foregoing warranties shall apply for a period of the lesser of
one (1) month from the date of installation or two (2) months from delivery to
DISTRIBUTOR. For any product or component purchased by SUPPLIER with a warranty
coverage available to DISTRIBUTOR for the relevant components. The foregoing
warranties are conditioned upon (a) proper storage, handling, transportation,
installation, use, repair, and maintenance, and conformance with any reasonable
recommendations of SUPPLIER, and (b) DISTRIBUTOR's promptly notifying SUPPLIER
of any defects and, if required, promptly making the Product or Pre-Commercial
Unit available for correction. The foregoing warranties are provided at no cost
to DISTRIBUTOR or Customers.

If any Product or Pre-Commercial Unit fails to meet the foregoing warranties
during the warranty periods set forth above, SUPPLIER shall thereupon correct
any such failure by either (with such choice to be solely SUPPLIER's) (a)
repairing the defective Product or Pre-Commercial Unit, or (b) replacing the
defective Product or Pre-Commercial Unit. All costs associated with such repair
or replacement, including any transportation costs, shall be the sole
responsibility of SUPPLIER, subject to the limitations set forth in the Service
Agreement described in the next paragraph.

DISTRIBUTOR will provide the labor, transportation, and other Services necessary
for such repairs and replacements pursuant to a Service Agreement that will be
mutually agreed between SUPPLIER and DISTRIBUTOR. If such Service Agreement is
not agreed to by June 1, 2000, then this Distributor Agreement will terminate.
The Service Agreement will set forth limits on SUPPLIER's reimbursement to
DISTRIBUTOR for labor, transportation, and other Services. The Service Agreement
will also set forth a warranty approval process that will include pre-approval
of major warranty claims prior to commencement of work, submission of all
warranty claims for review and approval by SUPPLIER, and return of all parts
subject to warranty claims to SUPPLIER.

For Products, SUPPLIER will provide DISTRIBUTOR with the option of purchasing an
extension to the initial warranty period. Such additional warranty period will
be for three years beyond the termination of the initial warranty period, and
will cover the fuel cell stack, control system, power conditioning system
(excluding batteries and recharger), and fuel processor (i.e., the extended
warranty covers all components except for the air humidifier assembly,
humidifier pump, system frame assembly, package skin assembly, manifold
assemblies, electrical harness assemblies, coolant pump and fan, cooling system
heat exchanger, fuel cell air blower, particulate air filter, air regulator,
water deionizing and purification system, batteries, recharger, and fuel
processing auxiliaries). The price for such warranty extension, if purchased,
will not exceed $750, to be paid as a lump sum at the time of Product purchase,
for Products purchased in "2001", as defined in Schedule D, and $500 for
                                                ----------
Products purchased thereafter. The extended warranty price  for "2001" is
not firm and will become firm no later than April 1, 2000. In the event that the
extended warranty price for "2001" exceeds $750, then SUPPLIER and DISTRIBUTOR
shall agree to a decrease to DISTRIBUTOR's Sales Commitments. If SUPPLIER and
DISTRIBUTOR cannot reach such agreement, then this Agreement shall terminate.
For Pre-Commercial Units, SUPPLIER will provide DISTRIBUTOR with the option of
purchasing an extension to the initial warranty period. Such additional warranty
period will be for one year beyond the termination of the initial warranty
period, and SUPPLIER will provide a firm price no later than October 1, 1999.

THE WARRANTIES SET FORTH IN THIS SECTION 7 ARE IN LIEU OF ALL OTHER WARRANTIES,
WHETHER ORAL, WRITTEN, EXPRESS, OR IMPLIED, INCLUDING WITHOUT LIMITATION IMPLIED
WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. SUPPLIER'S
WARRANTY OBLIGATIONS AND DISTRIBUTOR'S REMEDIES UNDER THIS SECTION 7 (EXCEPT AS
TO TITLE) ARE SOLELY AND EXCLUSIVELY AS STATED HEREIN.

8.  PROPER BUSINESS PRACTICES.  SUPPLIER and DISTRIBUTOR shall comply with all
laws dealing with improper or illegal payments, gifts or gratuities, and
SUPPLIER and DISTRIBUTOR agree not to pay, promise to pay or authorize the
payment of any money or anything of value, directly or indirectly to any person
for the purpose of illegally or improperly inducing a decision or obtaining or
retaining business in connection with a purchase order.

9.  COMPLIANCE WITH LAWS.  SUPPLIER and DISTRIBUTOR agree to comply with the
applicable provisions of any federal, state, provincial or local law or
ordinance and all lawful orders, rules, and regulations issued thereunder. No
forced or prison labor may be used in manufacturing the products to be supplied
under this Agreement. If forced or prison labor is determined to have been used
in the manufacture of the Products or Pre-Commercial Units supplied hereunder,
the DISTRIBUTOR shall have the right to immediately terminate the purchase order
and this Agreement without further compensation to the SUPPLIER; and, in such
case, DISTRIBUTOR shall return to SUPPLIER any Products or Pre-Commercial Units
for which it has not yet made payment.

Provisions applicable to orders for work to be performed, goods to be produced,
or services to be rendered within the United States.  (a) SUPPLIER shall comply
with any provisions, representations or agreements or contractual clauses
required thereby to be included or incorporated by reference or operation of law

DISTRIBUTOR hereunder is on the list of chemical substances compiled and
published by the Administrator of the Environmental Protection Administration
pursuant to the Toxic Substances Control Act (P.L. 92-573 as amended, and the
Federal Hazardous Substances Act (P.L. 92-516) as amended and lawful standards
and regulations thereunder. (d) In accepting an order SUPPLIER represents that
the goods to be furnished thereunder were or will be produced in compliance with
the requirements of the Fair Labor Standards Act of 1938, as amended, including
Section 12(a) and SUPPLIER shall insert a certificate to that effect on all
invoices submitted in connection with such order.

10.  PACKING, PRESERVATION AND MARKING. Packing, preservation and marking
requirements will be in accordance with the specification drawing or as
otherwise agreed by SUPPLIER and DISTRIBUTOR. If none are specified, SUPPLIER

11.  YEAR 2000 COMPLIANCE WITH DATE PROCESSING REQUIREMENTS.  In addition to any
other warranties and representations provided by SUPPLIER to DISTRIBUTOR,
whether pursuant to this Schedule B, by law, equity, or otherwise, SUPPLIER
                         ----------
represents, warrants and covenants that (a) any Product(s), Pre-Commercial
Unit(s) and/or Service(s) provided by SUPPLIER hereunder, including, without
limitation, each item of hardware, software, or firmware; any system, equipment,
or products consisting of or containing one or more thereof; and any and all
enhancements, upgrades, customizations, modifications, maintenance and the like,
performed approved, or contained in official documentation provided by SUPPLIER
("Products/Services") shall be Year 2000 Compliant at the time of delivery and
at all times thereafter and in all subsequent updates or revisions of any kind,
and (b) SUPPLIER's supply of the Products/Services to DISTRIBUTOR shall not be
interrupted, delayed, decreased, or otherwise materially affected by dates prior
to, on, after or spanning January 1, 2000. For purposes of this purchase order,
the term "Year 2000 Compliant" means that (1) the Products/Services accurately
process, provide and/or receive date data, within, from, into, and between
centuries (including without limitation, the twentieth and twenty-first
centuries, the last year of a century (e.g., 1999) and the first year of the
next century (e.g., 2000)), and leap year calculations, and (2) neither the
performance nor the functionality nor SUPPLIER's supply to DISTRIBUTOR of the
Products/Services will be materially affected by dates prior to, on, after, or
spanning January 1, 2000. Moreover, SUPPLIER covenants and agrees that the
design of said Products/Services to ensure compliance with the foregoing
warranties, representations and covenants shall include, without limitation,
date data century recognition, and date data interface values that reflect the
century. In particular, but without limitation, (i) no value for current date
will cause any error, interruption, or decreased performance in the operation of
such Products/Services, (ii) all manipulations of date-related data (including,
but not limited to, calculating, comparing, sequencing, processing, and
outputting) will produce correct results for all valid dates, (iii) date
elements in interfaces and data storage will specify the correct century to
eliminate date ambiguity without human intervention, including leap year
calculations, (iv) where any date element is represented without a century, the
correct century will be unambiguous for all manipulations involving that
element, (v) authorization codes, passwords, and zaps (purge functions) should
function normally and in the same manner prior to, on, after and spanning
January 1, 2000, including, without limitation, the manner in which they
function with respect to expiration dates and CPU serial numbers. No obligation
of SUPPLIER under a purchase order pursuant to this Agreement shall be excused
by reason of the failure of SUPPLIER's or any other person's products or


services to be Year 2000 Compliant, nor shall such occurrence(s) be deemed a
force majeure event. As used herein or in a purchase order, the words "date" and
"dates" shall be deemed to include "time".

In the event of breach of this warranty, in addition to any other remedies
DISTRIBUTOR may have, whether pursuant to this Schedule B, by law, equity or
                                               ----------
otherwise, DISTRIBUTOR shall, at SUPPLIER's option, be entitled to repair or
replacement of any non-compliant Products/Services, at SUPPLIER's cost, within
thirty (30) days after notice of breach from DISTRIBUTOR to SUPPLIER. In
addition to SUPPLIER'S obligations as set forth above, SUPPLIER shall indemnify
and hold DISTRIBUTOR harmless from and against any claims, costs, losses,
damages, or expenses (including reasonable attorneys' fees) incurred by
DISTRIBUTOR as a result of any failure of any Products/Services to be Year 2000
Compliant. Notwithstanding anything herein to the contrary, the liability of
SUPPLIER for a breach of SUPPLIER's Year 2000 Compliant representation, warranty
and agreement set forth herein shall not be subject to any limitations or
exclusions of remedies or warranties, if any, contained in a purchase order or
any other agreement between the parties.

Notwithstanding anything in a purchase order or in this Agreement to the
contrary, the period of the representations, warranties and covenants set forth
in this section shall extend at least until January 31, 2001. Any statute of
limitations that might be applicable to SUPPLIER's Year 2000 Compliant warranty
and representation shall not accrue or begin to run until the later of January
31, 2001, or the time when such statute of limitations would otherwise accrue or
begin to run, and, with respect to any claim based on any failure of the

                            SCHEDULE B (continued)
                            ----------------------

                              Pre-Commercial Unit
                          Performance Specifications

Note:   SUPPLIER and DISTRIBUTOR recognize that these specifications may change
- -------------------------------------------------------------------------------
based on further analysis of residential load profiles and field testing.  If
- -----------------------------------------------------------------------------
SUPPLIER and DISTRIBUTOR mutually agree to change the specifications set forth
- ------------------------------------------------------------------------------
below, SUPPLIER and DISTRIBUTOR agree to adjust the prices and purchase volumes
- -------------------------------------------------------------------------------
set forth in Schedule C.
- ------------------------

Testing protocol and acceptance criteria:
- -----------------------------------------

     On or before October 1, 1999, DISTRIBUTOR and SUPPLIER will agree on the
specific testing protocol and acceptance criteria for all Pre-Commercial Units
("PCUs") purchased by DISTRIBUTOR. The protocol and acceptance criteria will (a)
incorporate the field test results from the "Test and Evaluation Units" ("TEUs")
that SUPPLIER expects to have available beginning the second quarter of 1999;
and (b) address all aspects of PCU system and component performance that are
expected to impact regulatory approvals and end-user economics, including, but
not limited to, useful life, output, reliability, efficiency, operating
environment requirements, power quality, load following capability, and
emissions. In the event that DISTRIBUTOR and SUPPLIER are unable to agree on the
testing protocol and/or acceptance criteria this Agreement will terminate.


Packaging:
- ----------

     PCU product design will be complete to the point where interfaces between
major components (e.g., stack, reformer, inverter, etc.) will be similar to that
of the final Product. The overall PCU package size and weight must be suitable
for installation outside of a typical single family residence (and, where
practicable, inside a typical single family residence).


Certifications:
- ---------------

     Certifications (e.g., UL, NFPA, AGA, FCC Class B) are not required for the
PCUs. However, PCUs must meet any customary local codes and regulations required
for field testing by DISTRIBUTOR's Customers. To the extent the test site
requires preparation to meet local codes, any site improvements will be at the
Customer's expense.


Technology:
- -----------

     Basic technology of all major PCU components must be the same as that of
the Product; however, suppliers and manufacturers of the major components need
not be the same as those for the Product.



Interconnection:
- ----------------

     PCUs will be capable of interconnection to the electrical system of a
typical single family residence; provided however that the PCU will operate
isolated from the grid with the use of a transfer switch ("stand-alone
operation"). The transfer switch will, in the event that the PCU fails or is
interrupted, transfer the household load from the PCU back to the utility grid
within no more than one-tenth of a second.


Installation:
- -------------

     PCUs must be in compliance with any applicable NEC installation
requirements.


Documentation:
- --------------

     PCUs must be shipped with sufficient documentation (e.g., installation
drawings, operating manuals, repair guides) to allow for start-up and Service by
individuals with a skill level comparable to a typical HVAC technician, after
such individual has completed the SUPPLIER training program or a training
program approved by SUPPLIER.

     PCUs must be provided in strict accordance with samples, drawings, and/or
designs provided by SUPPLIER and approved in writing by SUPPLIER and
DISTRIBUTOR.


Technical Support:
- ------------------

     SUPPLIER will make available by telephone to DISTRIBUTOR and its Customers
PCU technical support during SUPPLIER's normal business hours. SUPPLIER will
also establish a 24-hour telephone number to accommodate emergency calls from
DISTRIBUTOR and its Customers.


Shipping:
- ---------

     SUPPLIER will prepare all PCUs to allow for standard commercial shipment
(e.g., truck, rail, cargo ship) to Customer locations.

Monitoring & Diagnostics:
- -------------------------

     PCUs will be designed to accommodate remote monitoring and diagnostics
("RM&D") equipment (e.g., modems, data collection/storage). RM&D equipment will
be provided, installed, and operated at DISTRIBUTOR's or its Customers' expense.
At a minimum, the PCU control system will allow the RM&D equipment to monitor
the following parameters:


         Current System Status
         Output Power
         Voltage
         Current

Note:   SUPPLIER and DISTRIBUTOR recognize that these specifications may change
- -------------------------------------------------------------------------------
based on further analysis of residential load profiles and field testing.  If
- -----------------------------------------------------------------------------
SUPPLIER and DISTRIBUTOR mutually agree to change the specifications set forth

- ---------------------------------------------------

Testing protocol and acceptance criteria:
- -----------------------------------------

     On or before June 1, 2000, DISTRIBUTOR and SUPPLIER will agree on the
specific testing protocol and acceptance criteria for all Products purchased by
DISTRIBUTOR. The protocol and acceptance criteria will (a) incorporate the field
test results from the PCUs; and (b) address all aspects of Product system and
component performance that are expected to impact regulatory approvals and end-
user economics, including, but not limited to, useful life, output, reliability,
efficiency, operating environment requirements, power quality, load following
capability, and emissions. In the event that DISTRIBUTOR and SUPPLIER are unable
to agree on the testing protocol and/or acceptance criteria this Agreement will
terminate.


Packaging:
- ----------

     Product package size and weight must be suitable for installation indoor or
outside of a typical single family residence within the Major Markets.


Certifications:
- ---------------

     Commercial units, including packaging, must be compliant with all requisite
standards (e.g., UL, NFPA, AGA, FCC Class B, CE) within the Major Markets. To
the extent the installation site requires preparation to meet local codes, any
site improvements will be at the Customer's expense.


Interconnection:
- ----------------

     Products will be capable of interconnection to the electrical system of a
typical single family residence; provided however that the Product will operate
isolated from the grid with the use of a transfer switch ("stand-alone
operation"). The transfer switch will, in the event that the Product fails or is
interrupted, transfer the household load from the Product back to the utility
grid within no more than one-tenth of a second.

     Should it be determined that DISTRIBUTOR's Customers require an
interconnection scheme other than stand-alone operation (e.g., grid parallel),
DISTRIBUTOR and SUPPLIER will jointly set the requirements of the new
interconnection scheme. To the extent the new interconnection scheme results in


an increase in SUPPLIER's Product cost, SUPPLIER will adjust DISTRIBUTOR's
transfer price proportionately.

     In the event that SUPPLIER offers Products with a heat recovery option and
such units require an interconnection scheme other than stand-alone operation,
DISTRIBUTOR and SUPPLIER will jointly set the requirements of the new
interconnection scheme.  To the extent the new interconnection scheme results in
an increase in SUPPLIER's Product cost, SUPPLIER will adjust DISTRIBUTOR's
transfer price proportionately.


Installation:
- -------------

     Products must be in compliance with any applicable installation
requirements within the Major Markets.


Documentation:
- --------------

     Products must be shipped with sufficient documentation (e.g., installation
drawings, operating manuals, repair guides) to allow for start-up and Service by
individuals with a skill level comparable to a typical HVAC technician, after
such individual has completed the SUPPLIER training program or a training
program approved by SUPPLIER.

     Products must be shipped with documentation sufficient for an average
homeowner to perform routine maintenance.

     Products must be provided in strict accordance with samples, drawings,
and/or designs provided by SUPPLIER and approved in writing by SUPPLIER and
DISTRIBUTOR.


Technical Support:
- ------------------

     SUPPLIER will make available by telephone to DISTRIBUTOR and its Customers
Product technical support during SUPPLIER's normal business hours.  SUPPLIER
will also establish a 24-hour telephone number to accommodate emergency calls
from DISTRIBUTOR and its Customers.


Shipping:
- ---------

     SUPPLIER will prepare all Products to allow for standard commercial
shipment (e.g., truck, rail, cargo ship) to Customer locations.

Monitoring & Diagnostics:
- -------------------------


     Products will be designed to accommodate remote monitoring and diagnostics
(RM&D) equipment (e.g., modems, data collection/storage).  RM&D equipment will
be provided, installed, and operated at DISTRIBUTOR's or its Customers' expense.
At a minimum, the Product control system will allow the RM&D equipment to
monitor the following parameters:

         Current System Status
         Output Power
         Voltage
         Current
         Others - TBD*

Prices shown are for the Products as specified in Schedule B.  Any modification

to the Schedule B specifications requested by DISTRIBUTOR that result in a
       ----------
change to SUPPLIER'S direct cost will cause the price to DISTRIBUTOR to be
changed by an equal amount.


Prices for the Pre-Commercial Units as shown are firm (i.e., not subject to
change).

Product prices as shown are not firm. On April 1 of each year, beginning April
1, 2000, SUPPLIER will provide DISTRIBUTOR with a 3-year forecast of Product
prices for the period nine months hence (e.g., on April 1, 2000, SUPPLIER will
provide DISTRIBUTOR with Product prices for the 3-year period beginning January
1, 2001). The first year of each of SUPPLIER's forecast will be a firm price
commitment (i.e., in the forecast provided to DISTRIBUTOR on April 1, 2000,
SUPPLIER's Product prices for 2001 will be firm).

Prices are based upon cumulative quantity purchased (e.g., if DISTRIBUTOR
purchases [***] Product units in year 1, the price for the first [***] units is
[***] per unit, the price for the second [***] units is [***] per unit, and
the price for the first [***] units purchased in year 2 is [***] per unit).

On or before July 1, 2000, DISTRIBUTOR will provide SUPPLIER with a forecast of
DISTRIBUTOR's monthly purchases for the 12 months beginning January 1, 2001.
Each of the first 3 months of DISTRIBUTOR's forecast (i.e., January 1, 2001 to
March 31, 2001) will be a firm order (i.e., subject to change at SUPPLIER's sole
discretion). DISTRIBUTOR's forecast for the final 9 months of the forecast
period (i.e., April 1, 2001 to December 31, 2001) is for SUPPLIER's planning
purposes only. DISTRIBUTOR, at its sole discretion, may change the monthly
purchase forecast in any month in the final 9-month forecast period by any
amount.

On the first business day of each month beginning October 1, 2000, DISTRIBUTOR
will provide SUPPLIER with a 12-month rolling forecast of monthly purchases for
the period beginning 3 months hence. Each of the first 3 months of DISTRIBUTOR's
forecast will be a firm order. DISTRIBUTOR's forecast for the final 9 months of
each forecast period is for SUPPLIER'S planning purposes only. DISTRIBUTOR, at
its sole discretion, may change the monthly purchase forecast in any month in
the final 9-month forecast period by any amount.

Any Products that DISTRIBUTOR is obligated to purchase, but otherwise unable to
sell, may be held in SUPPLIER's inventory at the request of DISTRIBUTOR.
Electing to have SUPPLIER hold DISTRIBUTOR's inventory does not relieve
DISTRIBUTOR of its obligation to purchase any of DISTRIBUTOR's units held in
inventory. DISTRIBUTOR will reimburse SUPPLIER for its fully loaded inventory
carrying cost, including warehouse expenses, interest, and any inventory
carrying cost charged to SUPPLIER by SUPPLIER's vendors as a direct result of
DISTRIBUTOR's request for SUPPLIER to hold inventory.

On or before April 1, 2000, SUPPLIER will provide DISTRIBUTOR with a firm price
for the monthly inventory carrying charge for 2001. On or before August 1 of
each subsequent year, SUPPLIER will provide DISTRIBUTOR with a firm price for
the monthly inventory carrying charge for the upcoming year.

Prices to DISTRIBUTOR for Product and Pre-Commercial Unit replacement parts will
not exceed SUPPLIER's fully loaded actual cost plus [***]. DISTRIBUTOR will have
the right to audit SUPPLIER's financial records to the extent necessary to
verify compliance with this provision.

Global Sales Commitments and Major Market Sales Commitments (collectively
"Commitments") as shown are expressed in 7kW equivalent units based on maximum
continuous output. If DISTRIBUTOR sells any units larger or smaller than 7kW,
the sales targets will be adjusted accordingly (e.g., DISTRIBUTOR can satisfy
its 2001 Global Sales Commitment with [***] units).

The Commitment for any 1-month period will be equal to [***] of the annual

SUPPLIER completes design and manufacturing of the lock-in system on April 1,
2000, then DISTRIBUTOR'S "calendar year" 2001 Global Sales Commitments and Major
Market Sales Commitments will run from April 1, 2001 to March 31, 2002).


Global Sales Commitments

DISTRIBUTOR shall be deemed to have achieved the Global Sales Commitments if
DISTRIBUTOR achieves global minimum sales of at least [***] of the Global Sales
Commitment in each relevant 12-month period.

In the event DISTRIBUTOR's total sales in the Territory in "2001" (defined
herein as the 12-month period commencing 12 months after SUPPLIER completes
design and manufacturing of the lock-in system, but no earlier than January 1,
2001) are less than [***], but more than [***], of the "2001" Global Sales
Commitment, DISTRIBUTOR must achieve sales in "2002" (defined herein as the
12-month period after the completion of "2001") of not less than [***] of the
"2002" Global Sales Commitment, or SUPPLIER shall have the right to name
additional distributors in the Territory for "2003" (defined herein as the
12-month period after the completion of "2002").


In the event DISTRIBUTOR's total sales in "2001" are less than [***], but more
than [***], of the "2001" Global Sales Commitment, DISTRIBUTOR must achieve
sales in the first 6 months of "2002" of not less than [***] of the Global Sales
Commitment for the first 6 months of "2002", or SUPPLIER shall have the right to
name additional distributors in the Territory beginning in month 7 of "2002".
In the event that DISTRIBUTOR's total sales in "2001" are less than [***], but
more than [***], of the "2001" Global Sales Commitment, and DISTRIBUTOR achieves
sales in the first 6 months of "2002" of not less than [***] of the Global Sales
Commitment for the first 6 months of "2002", DISTRIBUTOR must also achieve sales
for the 12-month period from month 7, "2002" through month 6, "2003" of not less
than [***] of the Global Sales Commitment for such 12-month period, or SUPPLIER
shall have the right to name additional distributors in the Territory for the
last 6 months of "2003".

In the event that, during any 12-month period, DISTRIBUTOR's total sales are
less than [***] of the Global Sales Commitment for such period, SUPPLIER shall
have the right to terminate this Agreement.


Major Market Sales Commitments

DISTRIBUTOR shall be deemed to have achieved the Major Market Sales Commitments
if DISTRIBUTOR achieves sales of at least [***] of each Major Market Sales
Commitment in each relevant 12-month period.

In the event DISTRIBUTOR's sales in a "Major Market" (defined herein as
U.S./Canada, and Western Europe) in "2001" are less than [***], but more than
[***], of the "2001" Major Market Sales Commitment for such Major Market,
DISTRIBUTOR must achieve sales in "2002" in such Major Market of not less than
[***] of the Major Market Sales Commitment for such Major Market in "2002", or
SUPPLIER shall have the right to name additional distributors in that Major
Market for "2003".

In the event that DISTRIBUTOR's sales in either Major Market in any 12-month
period are less than [***] of the Major Market Sales Commitment for such Major
Market for such period, SUPPLIER shall have the right to name additional
distributors in that Major Market.



However, in the event that DISTRIBUTOR's total sales exceed [***] of the Global
Sales Commitment for "2001" or "2002", SUPPLIER shall not be allowed to name
additional distributors in either Major Market for the following year (the
"Extension") (e.g., if DISTRIBUTOR achieves greater than [***] of the Global
Sales Commitment for "2001", then SUPPLIER may not name additional distributors
to either Major Market in "2002", regardless of DISTRIBUTOR's sales in the Major
Markets in "2001"). This Extension shall apply only one time, such that if this
clause applies in the "2001", it shall not apply in "2002".
