     2.   Amendments.  The Agreement is hereby amended as follows:
          ----------
          (a)     Section 1 of the Agreement is hereby amended by
     adding the following two definitions:

          "'GEFCS Shares' shall have the meaning set forth in the third recital
          of the First Amendment to Registration Rights Agreement dated as of
          July 25, 2001."

          "'Investment Shares' means the 416,666 shares of Common Stock issued
          to GEPS Equities on July 25, 2001."

          (b)     Section 1 is further amended by deleting the definition of
     "Registrable Securities" in its entirety and substituting the following in
     lieu thereof:

          "'Registrable Securities' means that number of shares of Common Stock
          equal to the aggregate number of (A) the Shares, (B) the GEFCS Shares,
          (C) the Investment Shares, and (D) any Common Stock issued or issuable
          with respect to Registrable Securities by reason of a stock dividend
          or stock split or in connection with a confirmation of shares,
          recapitalization, merger, consolidation or other reorganization."

          (c)     Section 2(a)(ii) of the Agreement is hereby amended by
     deleting that subsection in its entirety and substituting the following in
     lieu thereof:

                       "(i) Upon receipt of a request pursuant to Section
          2(a)(i) above, Plug Power shall give prompt written notice thereof to
          all other Investors who hold Registrable Securities. Upon receipt of
          such request, Plug Power shall use its best efforts to promptly effect
          the registration under the 1933 Act of all shares of Registrable
          Securities specified in the requests of the Initiating Holders and the
          written requests (stating the number of shares of Registrable
          Securities to be disposed of and the intended method of disposition of
          such shares) of other holders of shares of Registrable Securities
          given within 20 days after receipt of such notice from Plug Power, all
          to the extent requisite to permit the disposition (in accordance with
          the intended methods of disposition) of the Registrable Securities to
          be registered; provided that in no event will Plug Power be obligated
          to (A) register a number of shares of Registrable Securities pursuant
          to this Section 2(a) in excess of (x) 3,416,666 shares plus the
          aggregate number of GEFCS Shares (in each case as appropriately
          adjusted for stock splits, stock dividends, merger recapitalizations
          and similar transactions) less (y) the aggregate number of shares of
          Registrable Securities included in Registration Statements pursuant to
          Section 2(c) below (the "Registration Limit") or (B) effect more than
          one registration pursuant to this Section 2(a). In the event that the
          aggregate number of shares of Registrable Securities for which
          registration is requested in accordance with this Section 2(a) exceeds
          the Registration Limit, such aggregate number will be reduced to the
          Registration Limit and will be allocated among the

                                      2

<PAGE>

          holders requesting registration on a pro rata basis in proportion to
          the number of Registrable Securities requested to be registered by
          such holders."

          (d)     Section 2(c) of the Agreement is hereby amended by deleting
     the second paragraph thereof in its entirety and substituting the

          hereof, GEOSP and each Investor shall have the right on three
          occasions to request inclusion of the Registrable Securities in
          Registration Statements (excluding for purposes of determining such
          number of Registration Statements any Disqualified Registration
          Statement (as defined below)) pursuant to this Section 2(c). The
          rights of GEOSP and each other holder of Registrable Securities under
          this Section 2(c) will terminate on the date on which the third
          Registration Statement (excluding any Disqualified Registration
          Statement) in which their Registrable Securities have been so
          included has been declared effective by the SEC. The term
          "Disqualified Registration Statement" means any Registration
          Statement with respect to which Registrable Securities are requested
          to be included pursuant to this Section 2(c) where the aggregate

          Registration Statement is reduced pursuant to a Cutback Registration
          to a number of shares which is less than the lower of (x) 900,000 or
          (y) 80% of the aggregate number of shares of Registrable Securities
          requested to be included in such Registration Statement."

each of which shall be deemed an original or a facsimile or photocopy of an
original and all of which, taken together, shall be deemed one and the same
Amendment.

first. This Agreement may be terminated by a Party hereto prior to expiration
of the Term by furnishing prior written notice to the other Party, as follows:

              (a) Termination by SUPPLIER if (i) DISTRIBUTOR does not achieve
an annual total dollar value of purchases from SUPPLIER sufficient to make

output, cost of energy, fuel type, application) in the Territory, and (ii)
SUPPLIER has met all of its obligations as set forth in the Agreement;
provided, that no such termination shall be effective unless DISTRIBUTOR shall
--------
fail to remedy any such nonperformance within 120 days after receiving written
demand therefor.

process described in Section 2.8(b) hereof, a mutually agreeable remedy and/or

deviation from the MGPP when considered in its entirety, or (ii) SUPPLIER fails
to provide DISTRIBUTOR with Products which are, in the reasonable judgment of
GEMG, materially competitive with alternative PEM Fuel Cell-Powered Generator
Sets on the basis of cost of energy, output, fuel flexibility, combined heat
and power capability, first cost, lifecycle cost, reliability, emissions and
application, when viewed in the aggregate, provided that no such termination
                                           --------
shall be effective unless SUPPLIER shall fail to remedy any such nonperformance

should fail to perform any of its material obligations hereunder and such
failure results in a material adverse effect to the terminating Party, (ii) the
terminating Party provides written notice of such

which is furnished to others by the disclosing Party without restriction on
disclosure, which was or becomes known to the receiving Party through other
sources free of any confidentiality restriction, which must be disclosed by
requirements of law or valid legal or regulatory process, in which case the
Party intending to make such disclosure shall notify the Party which designated
the material as confidential in advance of any such disclosure and reasonably
cooperate with any attempt to maintain the confidentiality of such materials;
and (ii) any and all restrictions with respect to Confidential Information
provided hereunder will expire three (3) years after the date that such
Confidential Information is first disclosed to the receiving Party.

              (c) When one Party no longer desires to use the Confidential
Information of the other Party, it shall return to the other Party any such
Confidential Information and shall destroy all copies of such Confidential
Information with the exception of one copy which may be retained exclusively
for the purpose of documenting the disclosures made hereunder.

              (d) The receiving Party will restrict access to any Confidential
Information made available or disclosed by the disclosing Party to the
receiving Party hereunder only to those employees of the receiving Party with a

indirectly use SUPPLIER's trademarks (or part thereof), or any mark or name
confusingly similar thereto, as part of its corporate or business name, except

trademarks pertaining to the Products are subject to and protected by United
States trademark law, applications for registration of trademarks pertaining to
the Products have been filed in the United States, and similar applications
will be filed by SUPPLIER in other countries of the

<PAGE>

Territory designated by DISTRIBUTOR; provided that in the event that SUPPLIER
does not agree to file any such application in any country or other
jurisdiction in the Territory, DISTRIBUTOR shall, in SUPPLIER's sole
discretion, (i) sell the Products in such country or other jurisdiction without
SUPPLIER's trademark affixed, (ii) sell the Products in such country or other
jurisdiction with a different SUPPLIER trademark affixed (in which event, all
of SUPPLIER's representations, warranties, covenants, and indemnities herein

thereafter lawfully acquired or developed by such Party shall not be deemed to
be transferred to any other party by virtue of this Agreement. DISTRIBUTOR
shall not have the right pursuant to this Agreement to manufacture, duplicate,
or otherwise copy or reproduce any of the Products, or any parts thereof. The
use by either Party of any Intellectual Property of the other Party is

purpose of co-branding Products sold by DISTRIBUTOR (i.e., affixing
DISTRIBUTOR's Trademark to a Product that also bears the trademark of
SUPPLIER), and (c) permit DISTRIBUTOR's Sale of co-branded Products. In the
event that DISTRIBUTOR elects not to have SUPPLIER affix DISTRIBUTOR's
Trademark to the Products, DISTRIBUTOR will affix DISTRIBUTOR's Trademark to
the Products. DISTRIBUTOR shall use DISTRIBUTOR's Trademarks for display,
promotional, or advertising purposes in connection with solicitation of orders
for Products from Customers in the Territory. The only Products that may bear
DISTRIBUTOR's Trademark are

reasonably necessary to enforce and protect its trademarks, patents, and
Intellectual Property Rights relating to the Products. 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, or any part thereof (except for DISTRIBUTOR's
Trademark, as such trademark was affixed to such Product, 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 7.5. 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 Product, 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 MGPP 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 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 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, part, device, or process;

<PAGE>

(b) replace same with a non-infringing equivalent; or (c) remove said Product,
part, device, or process and refund the purchase price and the transportation
and installation costs thereof.

                                   ----------

                      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 as established pursuant to
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 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 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

<PAGE>

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 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 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 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 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 (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 or 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 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. DISTRIBUTOR must notify SUPPLIER in writing of such
defect or non-conformity within 30 days after delivery of the Products or
performance of Services, if applicable, or DISTRIBUTOR's rights under this
Section

<PAGE>

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 to
DISTRIBUTOR as provided hereunder; (b) SUPPLIER warrants and represents that all
Products and Services sold hereunder or pursuant hereto will be free from all
material defects in workmanship and material, and that the Products and Services
are provided in strict accordance with the specifications as established by
mutual agreement of SUPPLIER and DISTRIBUTOR, 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
or Services purchased under this Agreement, the foregoing warranties shall apply
for (a) Products to a period of the lesser of twelve (12) months from the date
of installation or eighteen (18) months from delivery to DISTRIBUTOR, and (b)
Services to a period twelve (12) months from the date such Services are
completed. For any components purchased by SUPPLIER with a warranty in excess of
the terms described above, SUPPLIER will make such extended 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 available for
correction. The foregoing warranties are provided at no cost to DISTRIBUTOR or
Customers.

If any Product or Service 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, (b) replacing the defective Product, or (c) re-performing
the defective portion of the Services performed. All costs associated with such
repair, replacement, or re-performance, including any transportation costs,
shall be the sole responsibility of SUPPLIER, subject to the limitations set
forth in a Service Agreement as mutually agreed to by SUPPLIER and DISTRIBUTOR.
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 commercial Products, SUPPLIER will provide DISTRIBUTOR with the option of
purchasing an extension to the initial warranty period. Such additional warranty
period will be for a period of at least * years beyond the termination of the
initial warranty period, and will cover the entire Product. The price for such
warranty extension will be established pursuant to Schedule C, and
                                                   ----------
made available as an option to DISTRIBUTOR.

WHETHER ORAL, WRITTEN, EXPRESS, OR IMPLIED, INCLUDING WITHOUT LIMITATION
IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.

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 for which it has not yet made payment.

with such order.

(e.g., SU1, SU2, SU3), no later than the completion of SUPPLIER's Design and
Verification phase (i.e., NPD Stage 3) for such Product. SUPPLIER's NPD process
stages are as set forth in the Business Plan. In the event that the Parties
cannot agree on the price for a given Product, both Parties shall be prohibited
from Selling such Product. Distributor and Supplier will use general pricing
principles as guidelines to be considered in negotiating pricing. These
principles will include, among others, the following:

     .  Both GEFCS and Plug Power must be profitable
     .  GEFCS to target X%-X% EBIT for X and beyond
     .  Plug Power to target X% gross margin for X and beyond, reflecting
        higher capital and R&D investment
     .  Both Parties must see a path toward target profitability
     .  Plug Power to benefit from decreases in manufacturing costs
     .  GEFCS to benefit from increase in sales volumes and reduced selling
        costs

                                   ----------
                        DISTRIBUTOR'S PURCHASE FORECAST

Provided that the Commercial Period has commenced prior to such dates:

1.     On or before January 1, 2002, DISTRIBUTOR will provide SUPPLIER with a
       forecast of DISTRIBUTOR's monthly purchases for the 12 months beginning
       April 1, 2002. Each of the first 3 months of DISTRIBUTOR's forecast
       (i.e. April 1, 2002 to June 30, 2002) will be a firm order.
       DISTRIBUTOR's forecast for the final 9 months of the forecast period
       (i.e. July 1, 2002 to March 31, 2003) 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.

2.     On the first business day of each month beginning February 1, 2002,
       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.

In the event that SUPPLIER makes material changes to the Product commercial
introduction dates set forth in the MGPP, then the Parties will mutually agree
to modify the January 1, 2002 start date for DISTRIBUTOR's purchase forecast.
In addition, purchase forecasts shall be modified to the extent Distributor
determines necessary on the occasion of each modification to the MGPP.

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,
provided that SUPPLIER has reasonably available space. Electing to have
SUPPLIER hold DISTRIBUTOR's inventory does not relieve DISTRIBUTOR of its
obligation to purchase and take delivery of 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 September 1, 2001, SUPPLIER will provide DISTRIBUTOR with a firm
price for the monthly inventory carrying charge for 2002. 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.
