                               September 7, 2000

PERSONAL & CONFIDENTIAL
-----------------------

Mr. Gary Mittleman

Dear Gary:

     This letter agreement (the "Agreement") confirms the agreement that we have
reached regarding the remainder of your employment and your separation from
employment with Plug Power Inc. ("Plug Power").

     You acknowledge that Plug Power disputes your contention that you are owed
any Termination Benefits under the Employment Agreement entered into by and
between you and the Board of Directors of Plug Power (the "Board") dated
June 27, 1997 and its Amendment dated January 14, 1999 (together, the
"Employment Agreement"). Notwithstanding this disagreement, to ensure that your
relationship with Plug Power remains amicable and to avoid costly litigation,
you and Plug Power agree to the terms below.

     By signing this Agreement, you are entering into this Agreement
voluntarily.  You understand that you are giving up your right to bring all
possible legal claims against Plug Power, among others, claims relating to your
employment and separation from employment.  You understand that by entering into
this Agreement, Plug Power is not admitting in any way that it violated any
legal obligation that it owed to you or to any other person.  To the contrary,
Plug Power's willingness to enter into this Agreement demonstrates that it is
continuing to deal with you fairly and in good faith.

     With those understandings and in exchange for the promises set forth below,
you and Plug Power agree as follows:

     1.   Effective Date.
          --------------

     This Agreement shall be deemed to have been executed as of the date of your
signature below (the "Execution Date").  The Agreement shall become effective on
the eighth (8th) day following the Execution Date (the "Effective Date") unless
you exercise your right to revoke in accordance with Section 14 below.

     2.   Remainder of Your Employment.
          ----------------------------

          (a) You shall resign from all offices (including, but not limited to,
your position as President and Chief Executive Officer) and your status as a
director of Plug Power and any affiliate or subsidiary of Plug Power that you
may hold effective as of August 23, 2000 (the "Transition Date").

          (b) Between the Transition Date and August 22, 2001, Plug Power shall
continue to employ you as a consultant.  Your duties and responsibilities as a
consultant shall be assigned to you from time to time by the Board, subject to
your reasonable availability, including, your schedule as determined by any
subsequent employer.

          (c) You shall resign from your employment with Plug Power effective as
of August 22, 2001 (the "Resignation Date").

          (d) Your employment under this Agreement may be terminated earlier
than the Resignation Date for "cause" without further liability on the part of
Plug Power.  The following conduct by you shall constitute "cause" for such
termination:

               (1) willfully and materially dishonest statements or acts with
     respect to Plug Power or any affiliate; or

               (2) failure to perform, to the reasonable satisfaction of the
     Board, any duty or responsibility under this Agreement; provided that,
     Plug Power shall provide you written notice of such failure to perform and
     allow you a reasonable opportunity to cure any such failure; or

               (3) breach of any obligation under this Agreement; provided that,
     Plug Power shall provide you written notice of such breach and allow you a
     reasonable opportunity to cure any such breach.

In the event that your employment terminates under this Section 2(d), the date
of that termination shall be deemed the "Resignation Date" under this Agreement.

     3.   Payments and Benefits.
          ---------------------

          (a)  Salary Continuation.
               -------------------
<PAGE>

Mr. Gary Mittleman
September 7, 2000
Page 3

     Plug Power shall continue to pay you your current base salary until the
Resignation Date.  You shall not be eligible for any other compensation after
the Transition Date. Notwithstanding the foregoing, any eligibility for Salary
Continuation shall expire upon your death.

          (b)  Benefits.
               --------

     Until the Resignation Date, you shall continue to be eligible for those
benefits provided by Plug Power to non-officer employees.  Following the
Resignation Date, to the extent that you are eligible for health benefits under
COBRA and elect such benefit continuation, you shall be responsible for paying
all health insurance premiums in full.  Pursuant to applicable benefit plan
terms and benefit practices, your eligibility to participate in all employee
benefit plans and programs shall cease effective on the Resignation Date.  Your
rights to benefits, if any, are governed by the terms of those benefit plans and
programs.

          (c)  Equity.
               ------

     Until the Resignation Date, options granted to you shall continue to vest,
in accordance with the governing stock option plans and all of the terms of
those plans shall continue to be in effect.  Similarly, until the Resignation
Date, you will make good faith efforts to sell your shares of Plug Power,
including any sale of shares pursuant to the exercise of your stock options, in
such a manner and at such times and in such volumes so as to minimize any
disruption in the trading of Plug Power's shares and to minimize the adverse
impact on the price of Plug Power's shares.

     4.   Tax Deductions and Reporting.
          ----------------------------

     Plug Power shall reduce payments made to you pursuant to this Agreement by
those deductions and withholdings that it reasonably determines to be required
for tax purposes and Plug Power shall make such tax-related reporting that it
reasonably determines to be required with respect to payments pursuant to this
Agreement.

     5.   General Release of Claims and Indemnification.
          ---------------------------------------------

          (a) Except for your rights and benefits under this Agreement, you
voluntarily release and discharge Plug Power and its parent companies,
affiliates, subsidiaries, predecessors, successors, and assigns, and the current
and former officers, directors, shareholders, employees, attorneys and agents of
each of the foregoing (any and all of which are referred to as the "Releasees")
generally from all charges, complaints, claims, promises, agreements, causes of
action, damages, and debts of any nature whatsoever, known or

          (b) You agree that you will not hereafter pursue any individual claim
against the Releasees by filing a lawsuit in any local, state or federal court
or agency for or on account of anything which has occurred up as a result of
your employment, including, your separation from employment, and you shall not
seek reinstatement with, or damages of any nature, severance pay, attorney's
fees, or costs from Plug Power in any forum; provided, however, that nothing in
this general release shall be construed to bar or limit your rights to enforce
your rights under this Agreement.

          (c) In accordance with Plug Power's applicable insurance policies and
applicable law, Plug Power shall defend, indemnify, and hold you harmless from
any and all damages and expenses with respect to suits, demands or proceedings
arising out of events, occurrences, or conduct occurring in connection with your
conduct as a director, officer, or employee of Plug Power so long as, with
respect to the events which give rise to such suit or demand, you acted in good
faith in the reasonable belief that your acts or omissions were in the best

in advance to keep such matters confidential. Nothing in this Agreement shall

your employment with Plug Power. You affirm and agree that through the Effective
Date, you have not disclosed and will not disclose the existence or terms of

                    association alone, without active involvement by you, with
                    an individual or entity that does engage in any such conduct
                    shall not constitute a violation of this Paragraph; and

              (ii)  soliciting or encouraging any Plug Power client or customer,
                    with which you worked in your capacity as a Plug Power
                    director, officer, or employee at any time, to engage any
                    person or entity other than Plug Power to perform any
                    service or provide any product previously performed or
                    provided by Plug Power ("Restricted Services") or to
                    terminate or otherwise modify adversely its business
                    relationship with Plug Power; provided that you may solicit
                    business from a Plug Power client or customer so long as it
                    is not business associated with Restricted Services; or

              (iii) soliciting or encouraging any Plug Power customer to engage
                    any person or entity other than Plug Power to perform any
                    Restricted Services or to terminate or otherwise modify
                    adversely its business relationship with Plug Power;
                    provided that you may solicit business from a Plug Power
                    client or customer so long as it is not business associated
                    with Restricted Services.

          (c) You understand that these restrictions are intended to protect
Plug Power's interest in its Confidential Information (as defined below) and
employee and customer relationships and goodwill, and agrees that such
restrictions are reasonable and appropriate for this purpose.

     10.  Confidential Information.
          ------------------------

     You understand and agree that your employment has created and will continue
to create a relationship of confidence and trust between you and Plug Power.
Accordingly, you will keep in confidence and trust all Confidential Information,
and will not use or disclose any such Confidential Information without the
written consent of Plug Power, except as may be necessary in the ordinary course
of performing your duties to Plug Power.  As used in this Agreement,
"Confidential Information" means information belonging to Plug Power which is of
value to Plug Power in the course of conducting its business and the disclosure
of which could result in a competitive or other disadvantage to Plug Power.
Confidential Information includes, without limitation, customer information,
information concerning Plug Power projects, technology, software, hardware, or
processes; financial information, reports, and forecasts; inventions,
improvements and other intellectual property; trade secrets; know-how; designs,
processes or formulae; market or sales information or plans; customer lists; and
business plans, prospects and opportunities (such as possible acquisitions or
dispositions of businesses or facilities) which have been discussed or
considered by the management of Plug Power.  Confidential Information includes
information developed by you in the course of your employment by Plug Power, as
well as other information to which you may have had access in connection with
your employment.  Confidential Information also includes the confidential
information of customers and/or any others with which Plug Power has a business
relationship.  Notwithstanding the foregoing, Confidential Information does not
include information in the public domain, unless due to breach of your duties
hereunder or actions by another person in violation of obligations or duties to
Plug Power which are attributable in whole or in part to any action by you.

     11.  Remedies.
          --------

     In the event that you violate any of the provisions of this Agreement,
Plug Power shall be entitled, if it so elects, to institute legal proceedings to
obtain damages for any such breach, or to enforce the specific performance by
you of any part or parts of this Agreement and to enjoin you from any further
violation, and may exercise such remedies cumulatively or in conjunction with
such other remedies as may be available to Plug Power at law or in equity. You
agree that it would be difficult to measure any damages to Plug Power which
might result from any breach by you of the promises set forth in this Agreement
and that in any event money damages would be an inadequate remedy for any such
breach. Accordingly, you agree that if you breach, or propose to breach, any
part or parts of this Agreement, Plug Power shall be entitled, in addition to
all other remedies that it may have, to an injunction or other appropriate
equitable relief to restrain any such breach, without showing or proving any
actual damage to Plug Power.

     12.  Enforceability.
          --------------

     If any portion or provision of this Agreement (including, without
limitation, any portion or provision of any Section of this Agreement) shall to
any extent be declared illegal or unenforceable by a court of competent
jurisdiction, then the remainder of this Agreement shall remain unaffected, and
each such portion and provision of this Agreement shall be valid and enforceable
to the fullest extent permitted by law.

     13.  Return of Documents.
          -------------------

     All documents, records, materials, software, equipment, and other physical
property, and all copies of any of the foregoing, that have come into your
possession or been produced by you in connection with your employment
("Property") have been and remain the sole property of Plug Power.  You shall
return to Plug Power all Property.

     14.  Notices, Acknowledgments and Other Terms.
          ----------------------------------------

     You are advised to consult with an attorney before signing this Agreement.

     This Agreement, including, the Employment Agreement, the applicable Stock
Option Plans, as amended, and agreements, and the Employee Patent and
Confidential Information Agreement by and between you and Plug Power dated
August 1, 1997, is the entire agreement between you and Plug Power regarding
your separation from employment, and all previous agreements, or promises
between you and Plug Power regarding the subject matter of this Agreement are
superseded, null, and void.  You agree that you have not relied on any statement
or representation, written or oral, by anyone affiliated with Plug Power,
concerning or related to the meaning of this Agreement.

     By signing this Agreement, you acknowledge that you are doing so
voluntarily.  You have been given the opportunity, if you so desired, to
consider this Agreement for twenty-one (21) days before executing it.  If not
signed by you and returned to me so that I receive it within twenty-one (21)
days of your receipt of this Agreement, this Agreement will not be valid.  In
the event that you execute and return this Agreement within less than twenty-one
(21) days, you acknowledge that such decision was entirely voluntary and that
you understood that you had the opportunity to consider this Agreement for the
entire twenty-one (21) day period. Plug Power acknowledges that for a period of
seven (7) days from the date of the
<PAGE>

Mr. Gary Mittleman

Page 9

execution of this Agreement, you shall retain the right to revoke this Agreement
by written notice received by the Chairman of Plug Power's Board before the end
of such period, and that this Agreement shall not become effective or
enforceable until the expiration of such revocation period. The Effective Date
of this Agreement shall be the date which is eight (8) days after the date of
execution of this Agreement. You understand that if you violate any of the terms
of this Agreement during the twenty-one (21) day consideration period or the
seven (7) day revocation period, this offer shall become null and void.

     In the event of any dispute, this Agreement will be construed as a whole,
will be interpreted in accordance with its fair meaning, and will not be
construed strictly for or against either you or Plug Power.  The laws of the
State of New York shall govern any dispute about this Agreement, including any
interpretation or enforcement of this Agreement, without giving effect to the
conflict of laws provisions of New York law.  In the event that any provision or
portion of a provision of this Agreement shall be determined to be
unenforceable, the remainder of this Agreement shall be enforced to the fullest
extent possible as if such provision or portion of a provision were not
included, except that if the General Release of Claims provision of this
Agreement (Section 5) is found to be unenforceable, in whole or in part, this
entire Agreement shall become null and void.  This Agreement may be modified
only by a written agreement signed by you and an authorized representative of
Plug Power.

     If you agree to these terms, please sign and date below and return this
Agreement to me within the time limitations set forth above.

                         Sincerely,

                         BOARD OF DIRECTORS of PLUG POWER INC.
