                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


1.  In the opinion of management the accompanying unaudited consolidated 
financial statements contain all adjustments, consisting of only normal, 
recurring adjustments, necessary for a fair presentation of results for such 
periods.  The results for any interim period are not necessarily indicative of 
results for the full year. Certain information and footnote disclosures normally
included in financial statements prepared in accordance with generally accepted 
accounting principles have been omitted. These consolidated financial statements
should be read in conjunction with the financial statements and notes thereto
for the fiscal year ended September 30, 1997.

2.  Income Taxes

The Company's effective tax rate for the nine months ended June 26,1998 and June
27, 1997 was 0% and 5.4%, respectively. The June 26, 1998 rate reflects the use 
of net operating losses and a full valuation allowance against the deferred tax 
assets generated by the losses on discontinued operations.

3.  Earnings per Share

The reconciliation of the numerators and denominators of Earnings per Share and
Earnings per Share-assuming dilution are as follows:

During the first three quarters of fiscal 1998,options to purchase 20,000 shares
of common stock at prices ranging from $5.70 to $6per share were outstanding but
were not included in the computation of Earnings per Share-assuming dilution
because the options' exercise price was greater than the average market price of
the common shares. The options, which expire between October 20, 2007 and April
27, 2008, were still outstanding at June 26, 1998.

During the first three quarters of fiscal 1997, options to purchase 188,100 
shares of common stock at a price of $2.44 per share were outstanding but were 
not included in the computation of Earnings per Share-assuming dilution because 
the exercise price was greater than the average market price of the common 
shares.  Therefore, no potential common shares are included in the computation.
The options, which expire between December 20, 2006 and March 14, 2007, were 
still outstanding at June 27, 1997.

4.  Discontinued Operations - Restatement

All remaining assets of the Company's Technology Division, the sole component of
the Technology segment, were sold to NYFM, Incorporated (a wholly-owned 
subsidiary of Foster Miller, Inc., a Waltham, Massachusetts-based technology 
company) on March 31, 1998.  In exchange for the Technology Division's assets, 
NYFM, Incorporated a) agreed to pay the Company a percentage of gross sales in 
excess of $2.5 million for a period of five years; b) assumed approximately 
$40,000 of liabilities; and c) established a credit for warranty work of 
approximately $35,000.  Accordingly, the Company no longer includes Technology 
among its reportable business segments and now operates in only one segment,Test
& Measurement.  The Technology Division is reported as a discontinued operation 
as of December 26, 1997, and the consolidated financial statements have been 
reclassified to report separately the net assets and operating results of the 
business.  The Company's prior year financial statements have been restated to 
conform to this treatment.

7. Investment in Plug Power, L.L.C.

On April 15, 1998, Edison Development Corporation ("EDC") contributed $2.25 
million in cash to Plug Power, L.L.C. ("Plug Power").  The Company contributed a
below-market lease for office and manufacturing facilities in Latham, New York, 
valued at $2 million and purchased a one year option to match the remaining 
$250,000 of EDC's contribution.  In May 1998, EDC contributed an additional $2 
million to Plug Power and the Company purchased a one year option to match the 
contribution.  The Company paid approximately $191,000 for the options, which 
mature in April 1999 ($250,000) and May 1999 ($2 million).

On July 31, 1998, Plug Power asked the Company and EDC to each commit to 
contribute an additional $5 million dollars (in cash and research credits) 
between August 5, 1998 and March 31, 1999.  Such contributions, if made, will 
increase the Company's total contributions to Plug Power(including contributions
of cash, assets, research credits, and a below market lease) to $11.75 million 
over the period commencing on June 27, 1997, and ending on March 31, 1999.  In 
addition, unless the Company exercises its options to match EDC's previous 
contributions of $250,000 in April 1999, and $2 million in May 1999,such options
will lapse.  The Company, EDC and Plug Power are currently negotiating whether, 
when and how, such additional contributions will be made.  If EDC and/or the 
Company do not contribute or lend additional funds to Plug Power, and no 
additional sources of funding can be found,Plug Power will be unable to continue
as a going concern.

The Company, EDC and Plug Power intend to determine the form, timing and pricing
of additional contributions or loans to Plug Power,if any, for the period August
1, 1998 through March 31, 1999, not later than September 15, 1998. On August 5,
1998, EDC and the Company made short term loans to Plug Power of $500,000 each.
If the Company, EDC and Plug Power have not agreed upon the terms and timing of
additional contributions to Plug Power, if any, as of September 15, 1998, such
loans will be payable upon demand.

              MECHANICAL TECHNOLOGY INCORPORATED AND SUBSIDIARIES
                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

The Company has recorded its proportionate share of Plug Power's losses only to
the extent of its recorded investment in Plug Power, such investment is zero as
of June 26, 1998.  

To the extent the Company makes investments in Plug Power,it will also recognize
its proportionate share of losses to the extent of these investments.

8.  Commitments

The Industrial Development Agency for the Town of Colonie has agreed to issue $6
million in Industrial Development Revenue ("IDR") Bonds on behalf of the Company
to assist in the construction of a new building for Advanced Products and the
Company's corporate staff and renovation of existing buildings to be leased to
Plug Power, L.L.C.  The construction project is due to be completed in December
1998.  First Albany Companies, Inc. ("FAC"), the Company's controlling
shareholder, will underwrite the sale of the IDR Bonds.  Proceeds of the IDR
Bonds will be deposited with a trustee for the bondholders. The Company may draw
the bond proceeds to cover qualified project costs. The bond closing is expected
to be completed on or about August 30, 1998.  FAC will receive no fees for
underwriting the IDR Bonds but will be reimbursed for its out-of-pocket costs.

9.  Subsequent Events

Debt
- ----
On July 15, 1998, the Company received a commitment from KeyBank National
Association ("KeyBank") to lend the Company $4 million in a working capital line
of credit at an interest rate of LIBOR plus 250 basis points, and a $1 million
equipment loan/lease line of credit at an interest rate of LIBOR plus 275 basis
points, both of which expire January 31, 2000.  Additionally, KeyBank has agreed
to issue a $6 million direct pay letter of credit to enhance the $6 million IDR
Bonds to be issued on the Company's behalf on or about August 30, 1998. The loan
commitment requires the Company to meet certain covenants, including a fixed
charge coverage and leverage ratio.  Further, if certain performance standards
are achieved, the interest rates on the debt may be reduced.  The commitment
letter also require the Company to grant a first lien on all consolidated assets
of the Company exclusive of Plug Power, L.L.C., a first mortgage on all land and
buildings owned by the Company and a first lien on any equipment purchased bythe
Company.

Rights Offering
- ---------------
On July 22, 1998, the Company filed a Registration Statement for the sale of 
additional common stock to current shareholders through the issuance of non-
transferable rights. The offering will raise up to approximately $6 million. The
Company will use some or all of the proceeds of the offering for investment in
and/or loans to Plug Power.  In addition, some proceeds may be used for 
acquisitions for the Company's core businesses,efforts to increase market share,
working capital, general corporate purposes and other capital expenditures.

             MECHANICAL TECHNOLOGY INCORPORATED AND SUBSIDIARIES
                    MANAGEMENT'S DISCUSSION AND ANALYSIS
              OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS


The following is management's discussion and analysis of certain significant 
factors, which have affected the Company's earnings during the periods included
in the accompanying consolidated statements of income.

  The sale of the Company's Technology Division, the sole component of the 
Technology segment, to NYFM, Incorporated (a wholly owned subsidiary of Foster-
Miller, Inc., a Waltham, Massachusetts-based technology company) on March 31,
1998 completed management's planned sale of non-core businesses. Accordingly,the
Company no longer includes Technology among its reportable business segments and
now operates in only one segment, Test & Measurement. The Technology Division is
reported as a discontinued operation as of December 26, 1997, and the
consolidated financial statements have been restated to report separately thenet
assets and operating results of the business. Net assets of the discontinued
operation were $649 thousand and $3,186 thousand at June 26, 1998 and September
30, 1997, respectively and the loss on discontinued operations included a loss
from operations of $516 thousand and a loss on disposal of $1,769 thousand for
the nine month period ended June 26, 1998. The loss on disposal includes a
provision for estimated operating results prior to disposal. The Company's prior
year financial statements have been restated to conform to this treatment.

Continuing Operations
- ---------------------
  Sales increased $146 thousand to $5,767 thousand for the three months ended 
June 26, 1998 as compared to $5,621 thousand for the three months ended June 27,
1997, a 2.6% increase.  This change is the result of an approximate $1 million
increase in sales for Advanced Products, which more than offset the sales 
reduction resulting from the September 30, 1997 sale of the L.A.B. Division. The
L.A.B. Division reported sales of $889 thousand and operating income of $106
thousand for the three months ended June 27, 1997.  Operating income increased
$810 thousand to $841 thousand for the three months ended June 26, 1998 as
compared to $31 thousand for the three months ended June 27, 1997, a 2,612.9%
increase.  The increase is the result of increased sales levels for Advanced
Products and improved margins as a result of cost control measures.

  Sales for the first three quarters of fiscal year 1998 versus the same period
in fiscal year 1997 have decreased $2.2million to $16million in 1998 from $18.2
million in 1997, a 12% decrease.  This decrease is attributable to the reduction
of sales resulting from the sale of the L.A.B. Division on September 30, 1997,
which reported sales of $2,617 thousand and operating income of $309thousand for
the first three quarters of fiscal 1997. The first three quarters of fiscal 1998
operating income of $1,814 thousand represented a $479 thousand increase or a
35.9% increase from the $1,335thousand operating income recorded during the same
period last year. The increase is the result of increased sales levels for
Advanced Products and improved margins as a result of cost control measures.

Other
- -----
  In addition to the matters noted above, during the first three quarters of
fiscal 1997, the Company recorded a $2.5 million extraordinary gain, net of 
taxes, on the extinguishment of debt.

    


<PAGE>
            MECHANICAL TECHNOLOGY INCORPORATED AND SUBSIDIARIES
                    MANAGEMENT'S DISCUSSION AND ANALYSIS
             OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

   Results during the first three quarters of fiscal 1998 and fiscal 1997 were
enhanced by lower interest expense, principally resulting from reduced
indebtedness.  Moreover, the Company benefited from reduced income tax expense
due to the use of net operating loss carryforwards.  However, as a result of
ownership changes, the availability of further net operating loss carryforwards
to offset future taxable income will be significantly limited pursuant to the
Internal Revenue Code.  The tax rate for the nine months ended June 26, 1998 and
June 27, 1997 was 0% and 5.4%, respectively. The June 26, 1998 rate reflects the
use of net operating losses and a full valuation allowance against the deferred
tax assets generated by the losses on discontinued operations.

Financial Condition
- -------------------
   The Company's working capital of $6.52 million at June 26, 1998 reflects a
$1.18 million decline from September 30, 1997.

   At June 26, 1998, cash and cash equivalents were $307 thousand versus $1.42
million at September 30, 1997.  Net cash used by operating activities for the
first nine months of fiscal 1998 amounted to $1.18 million, as compared to cash
used of $828 thousand in the prior year.  

   The capital used during the first three quarters of fiscal 1998 was
applied principally to fund short term operating cash flow requirements and
pay estimated taxes.  Additionally, accounts receivable increased to $5.59 
million or 24.7% as of June 26, 1998 as compared to $4.48 million as of 
September 30, 1997.  

   Capital spending during the first nine months of fiscal 1998 was $202 
thousand, a decrease from the comparable period in 1997 during which capital
spending totaled $322 thousand.  Capital spending during the fourth quarter of
fiscal 1998 and the first quarter of fiscal 1999 will reflect the construction
of a new building for Advanced Products and Corporate staff and renovations to
an existing building to be leased to Plug Power, L.L.C.  Total capital
spending for this project is expected to be approximately $6 million. 

   The reduction in net assets of discontinued operations of $2,537 thousand 
includes the transfer of $878 thousand of assets to continuing operations
(principally land, building and management information systems) as well as the
accrual for the loss on disposal of the Technology Division.  Such accrual
included a provision for estimated operating results prior to disposal and an
estimate of the loss on disposal and winddown of the Technology Division, which
totaled $1,769 thousand. The sale of the Technology Division was completed as of
March 31, 1998. 

   During fiscal 1996, First Albany Companies, Inc. ("FAC") purchased 909,091
shares of the Company's common stock from the New York State Superintendent of
Insurance as the court-ordered liquidator of United Community Insurance Company
("UCIC"). In connection with this purchase, FAC had also acquired certain rights
to an obligation ("Term Loan") due from the same finance company ("FCCC")to whom
the Company was obligated under the Note Payable.FCCC was in default of its Term
Loan to UCIC. FAC, as the owner of the rights to the Term Loan, filed suit-
seeking payment.  Collateral for the FCCC Term Loan included the Company's Note
Payable to FCCC. FAC exercised its rights to the collateral securing the Term
Loan,including the right to obtain payment on the Note Payable directly from the
Company.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS
              OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

   On December 27, 1996, the Company and FAC entered into an agreement under
which the Company issued to FAC 1.0 million shares of common stock in full
satisfaction of the Note Payable of $3.0 million and accrued interest of $1.2
million. Accordingly, the Company realized a gain on the extinguishment of debt
totaling $2.5 million, net of approximately $100 thousand of transaction related
expenses and net of taxes of $106 thousand.

   The Company anticipates that it will be able to meet the liquidity needs of
its continuing operations during fiscal year 1998 from cash flow generated by
operations, borrowing under its existing line of credit and, if consummated, the
newly committed line of credit from KeyBank N.A.

Debt
- ----
   On July 15, 1998, the Company received a commitment from KeyBank National
Association ("KeyBank") to lend the Company $4 million in a working capital line
of credit at an interest rate of LIBOR plus 250 basis points, and a $1 million
equipment loan/lease line of credit at an interest rate of LIBOR plus 275 basis
points, both of which expire January 31, 2000.  Additionally, KeyBank has agreed
to issue a $6 million direct pay letter of credit to enhance the $6 million IDR
Bonds to be issued on the Company's behalf on or about August 30, 1998. The loan
commitment requires the Company to meet certain covenants, including a fixed
charge coverage and leverage ratio.  Further, if certain performance standards
are achieved, the interest rates on the debt may be reduced.  The commitment
letter also requires the Company to grant a first lien onall consolidated assets
of the Company exclusive of Plug Power, L.L.C., a first mortgage on all land and
buildings owned by the Company and a first lien on any equipment purchased bythe
Company.  

   The Industrial Development Agency for the Town of Colonie has agreed to issue
$6 million in Industrial Development Revenue Bonds ("IDR") on behalf of the
Company to assist in the construction of a new building for Advanced Productsand
the Company's corporate staff and renovation of existing buildings to be leased
to Plug Power, L.L.C.  The construction project is due to be completed as of
December 1998.  First Albany Companies, Inc. ("FAC"), which owns 34% of the
Company's stock, will underwrite the sale of the IDR Bonds.  Proceeds of the IDR
Bonds will be deposited with a trustee for the bondholders. The Company may draw
the bond proceeds to cover qualified project costs. The bond closing is expected
to be completed on or about August 30, 1998.  FAC will receive no fees for
underwriting the IDR Bonds but will be reimbursed for its out of pocket costs.

Equity
- ------
   On July 22, 1998, the Company filed a Registration Statement for the sale of
additional common stock to current shareholders through the issuance of non-
transferable rights.The anticipated proceeds of up to approximately $6 million
will be used for investment in and/or loans to Plug Power, L.L.C., acquisitions
for the Company's core businesses and other general corporate business purposes.

             OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Joint Venture
- -------------
   On July 31, 1998, Plug Power, L.L.C. asked the Company to commit to
contribute $5 million (in cash and research credits) to Plug Power, L.L.C. to
fund continuing operations for the period August 1, 1998 through March 31, 1999.
The Company, EDC and Plug Power, L.L.C. are currently negotiating whether, when
and how, such additional contributions will be made.  On August 5, 1998, EDC and
the Company each made short-term loans of $500,000 to Plug Power, L.L.C.  If the
Company, EDC and Plug Power, L.L.C. have not agreed upon the terms and timing of
additional contributions to Plug Power, L.L.C. as of September 15, 1998, these
loans will be payable on demand.  In addition, Plug Power, L.L.C. will continue
to need substantial investment for the foreseeable future.  Plug Power, L.L.C.
continues to pursue strategic partners and additional sources of capital.  Plug
Power, L.L.C. is currently negotiating with several strategic partners and has
signed a preliminary Memorandum of Understanding with one strategic partner.
There is no assurance, however, that Plug Power, L.L.C. will successfully
conclude any transactions with strategic partners or find other sources of
capital.  If other sources of funding cannot be found, the Company will be faced
with contributing and/or lending additional capital to Plug Power, L.L.C. or
dilution of its interest in Plug Power, L.L.C.  If EDC and the Company stop
funding Plug Power, L.L.C. and no additional sources of capital are found, Plug
Power, L.L.C. will not be able to continue as a going concern.

Year 2000
- ---------
   The Company relies on both internal systems and systems of other parties in
regard to its business, accounting and operational software.  As the millennium
approaches, the Company is working toward becoming year 2000 compliant.  Many of
the Company's internal systems and products that have integrated software are
already year 2000 compliant.  The Company currently has plans that if successful
will have all internal systems and all of our products year2000 complaint during
fiscal 1999.

   The Company has contacted its outside software providers regarding their
products compliance with year 2000 issues and has developed specific plans to
address any non-compliant products.  These providers are in the process of
implementing these plans with an expected completion date of 1999.  If any
provider is not successful, the Company will evaluate selecting alternative
providers at that time.

   The incremental costs of assuring that the Company's products and purchased
software and products are year 2000 complaint are estimated to be approximately
$120,000.  Most of these costs are attributable to software/hardware upgrades.
The Company presently believes that with modifications to existing software or
conversion to new software, year 2000 problems can be effectively mitigated.
However, if such modifications and conversions are not made,or are not completed
timely, or if other issues that have not been anticipated arise, year 2000
problems could have a material impact on the operations of the Company.

                       PART II  OTHER INFORMATION

Item 1.  Legal Proceedings
- --------------------------
On January 30, 1998, Stephen Sullivan, former President of Ling Electronics,
Inc., a wholly-owned subsidiary of the Company, filed suit in Superior Court of
the State of California against Ling Electronics, Inc., alleging age
discrimination and wrongful termination claims against the Company arising from
the termination of Mr.Sullivan's employment by Ling, seeking unspecified relief.
The Company is currently in settlement negotiations with Mr. Sullivan.

In May 1998,the Company paid $138,580.30 in satisfaction of all of the Company's
obligations for past or future EPA response costs and any costs incurred by the
PRP's with respect to the site as its share of the Settlement of the
Environmental Protection Agency's executed consent decree with the Company and
other named potentially responsible parties in connection with a alleged release
of hazardous materials into the environment at a site in Malta, New York.

In February, 1997, an unaffiliated entity, Ling Holdings Group, Inc.
("Plaintiff"), brought suit against the Company.  The Plaintiff's claims 
arise out of the Company's decision not to sell Plaintiff the stock of the 
Company's wholly owned subsidiary, Ling Electronics, Inc. ("LING"), after 
expiration of the closing date specified in the stock purchase agreement 
and side letters executed in connection with the transaction 
(collectively, the "Agreements").  Plaintiff claims that the Agreements 
provided an "open-ended" closing that permitted Plaintiff to purchase LING 
when Plaintiff raised sufficient funds to do so.  Plaintiff further claims 
breach of express and implied contractual obligations, fraud, 
misrepresentation, and other torts in connection with the Company's 
refusal to consummate the sale after the agreed upon closing date.  
Plaintiff further alleged that the Company wrongfully confiscated $50,000 
of Plaintiff's escrowed funds in breach of the escrow agreement between 
Plaintiff, the Company, and the Adirondack Trust Company ("Escrow Agent"). 
Escrow Agent commenced an interpleader action regarding the escrowed funds 
in September, 1997.

The Company believes that its determination not to sell LING to Plaintiff 
was in compliance with the terms of the Agreements.  The Company further 
believes that it became the rightful owner of funds escrowed with the 
Escrow Agent, when Plaintiff failed to have sufficient funds available to 
close the purchase of LING on the closing date specified in the 
Agreements. The Company has filed claims against Plaintiff for negligent 
misrepresentation, asserting that Plaintiff misled the Company concerning 
its ability to raise the funds required to purchase LING.

The Ling Holdings Group, Inc. lawsuit trial date has been postponed until 
September 21, 1998. 

Item 4.  Submission of Matters to a Vote of Security Holders

then the Contractor may require that a Change Order be issued to adjust the

provided below and elsewhere in the Contract Documents. 

12.1.2 	The period covered by each Application for Payment shall be one calendar
month ending on the last day of the month, or as follows: 
	
12.1.3   Provided that an Application for payment is received by the Architect
not later than the LAST day of a month. The Owner* shall make payment to the 
Contractor not later than the TWENTY-FIRST day of the FOLLOWING month. If an
Application  for Payment is received by the Architect after the application date
fixed above, payment shall be made by the Owner not later than THIRTY days
after the Architect receives the Application for Payment. *UPON APPROVAL OF 
THEIR BANK

12.1.4  With each Application for Payment, the Contractor shall submit payrolls,
petty cash accounts, receipted invoices or invoices with check vouchers
attached, and any other evidence required by the Owner or Architect to
demonstrate that cash disbursements already made by the Contractor on account
of the Cost of the Work equal or exceed (1) progress payments already received
by the Contractor; less (2 ) that portion of those payments attributable to the
Contractor's Fee; plus (3) payrolls for the period covered by the present
Application for Payment.





<PAGE>
12.1.5  Each Application for Payment shall be based on the most recent schedule
of values submitted by the Contractor in accordance with the Contract
Documents. The schedule of values shall allocate the entire Guaranteed Maximum
Price among the various portions of the Work, except that the Contractor's Fee
shall be shown as a single separate item. The schedule of values shall be
prepared in such form and supported be such data to substantiate its accuracy
as the Architect may require. This schedule, unless objected to by the
Architect, shall be used as a basis for reviewing the Contractor's Applications
for Payment.

12.1.6 	Applications for Payment shall show the percentage of completion of
each portion of the Work as of the end of the period covered by the Application
for Payment. The percentage of completion shall be the lesser of (1) the
percentage of that portion of the Work which has actually been completed; or
(2) the percentage obtained by dividing (a) the expense that has actually been
incurred by the Contractor on account of that portion of the Work for which the
Contractor has made or intends to make actual payment prior to the next
Application for Payment by (b) the share of the Guaranteed Maximum Price
allocated to that portion of the Work in the schedule of values. 

12.1.7 	Subject to other provisions of the Contract Documents, the amount of
each progress payment shall be computed as follows: 

        .1      take that portion of the Guaranteed Maximum Price properly 
allocable to completed work as determined by multiplying the percentage of
completion of each portion of the Work by the share of the Guaranteed Maximum
Price allocated to that portion of the Work in the schedule of values.
Pending final determination of cost to the Owner of changes in the Work,
amounts not in dispute shall be included as provided in Subparagraph 7.3.8
of AIA Document A201- 1997;

        .2      add that portion of the Guaranteed Maximum Price properly 
allocable to materials and equipment delivered and suitably, stored at the 
site for subsequent incorporation in the Work, or if approved in advamce
by the Owner, suitably stored off the site at a location agreed upon in
writing; 
        .3      add the Contractor's Fee, less retainage of TEN - percent
(10% ). The Contractor's Fee shall be computed upon the Cost of the Work
described in the two preceding Clauses at the rate stated in Subparagraph
5.1.2 or, if the Contractor's Fee is stated as a fixed sum in that
Subparagraph, shall be an amount that bears the same ratio to that fixed-sum
fee as the Cost of the Work in the two preceding Clauses bears to a
reasonable estimate of the probable Cost of the Work upon its completion;

        .4      subtract the aggregate of previous payments made by the Owner;

        .5      subtract the shortfall, if any, indicated by the Contractor in
the documentation required by Paragraph 12.1.4 to substantiate prior
Applications for Payment, or resulting from errors subsequently discovered
by the Owner's accountants in such documentation; and

        .6      subtract amounts, if any, for which the Architect has
withheld or nullified a Certificate for Payment as provided in Paragraph 9.5
of AIA Document A201-1997.





<PAGE>
12.1.8 	Except with the Owner's prior approval, payments to Subcontractors
shall be subject to retainage of not less than FIVE percent ( 5 %). The Owner
and the Contractor shall agree upon a mutually acceptable procedure for review
and approval of payments and retention for Subcontractors.
 
12.1.9 	In taking action on the Contractor's Applications for Payment, the
Architect shall be entitled to rely on the accuracy and completeness of the
information furnished by the Contractor and shall not be deemed to represent
that the Architect has made a detailed examination, audit or arithmetic
verification of the documentation submitted in accordance with Subparagraph
12.1.4 or other supporting data; that the Architect has made exhaustive or
continuous on-site inspections or that the Architect has made examinations to
ascertain how or for what purposes the Contractor has used amounts previously
paid on account of the Contract. Such examinations, audits and verifications,
if required by the Owner, will be performed by the Owner's accountants acting
in the sole interest of the Owner.

12.2 	FINAL PAYMENT

12.2.1 	Final payment, constituting the entire unpaid balance of the Contract
Sum, shall be made by the Owner to the Contractor when:  

        .1      the Contractor has fully performed the Contract except for
the Contractor's responsibility to correct Work as provided in Subparagraph
12.2.2 of AIA Document A201-1997, and to satisfy other requirements, if any,
which extend beyond final payment; and

        .2      a final Certificate for Payment has been issued by the
Architect.

12.2.2  The Owner's final payment to the Contractor shall be made no later
than 30 days after the issuance of the Architect's final Certificate for
Payment, or as follows:
 
12.2.3  The Owner's accountants will review and report in writing on the
Contractor's final accounting within 30 days after delivery of the final
accounting to the Architect by the Contractor. Based upon such Cost of the
Work as the Owner's accountants report to be substantiated by the Contractor's
final accounting, and provided the other conditions of Subparagraph 12.2.1 have
been met, the Architect will, within seven days after receipt of the written
report of the Owner's accountants, either issue to the Owner a final Certificate
for Payment with a copy to the Contractor, or notify the Contractor and Owner
in writing of the Architect's reasons for withholding a certificate as provided
in Subparagraph 9.5.1 of the AIA Document A201-1997. The time periods stated in
this Subparagraph 12.2.3 supersede those stated in Subparagraph 9.4.1 of the
AIA Document A201-1997.

12.2.4 	If the Owner's accountants report the Cost of the Work as substantiated
by the Contractor's final accounting to be less than claimed by the
Contractor, the Contractor shall be entitled to demand arbitration of the
disputed amount without a further decision of the Architect. Such demand for
arbitration shall be made by the Contractor within 30 days after the
Contractor's receipt of a copy of the Architect's final Certificate for Payment;






<PAGE>
failure to demand arbitration within this 30-day period shall result in the
substantiated amount reported by the Owner's accountants becoming binding on the
Contractor. Pending a final resolution by arbitration, the Owner shall pay the
Contractor the amount certified in the Architect's final Certificate for
Payment.

12.2.5	 If, subsequent to final payment and at the Owner's request, the
Contractor incurs costs described in Article 7 and not excluded by Article 8 to
correct defective or nonconforming Work, the Owner shall reimburse the
Contractor such costs and the Contractor's Fee applicable thereto on the same
basis as if such costs had been incurred prior to final payment, but not in
excess of the Guaranteed Maximum Price. If the Contractor has participated in
savings as provided in Paragraph 5.2, the amount of such savings shall be
recalculated and appropriate credit given to the Owner in determining the net
amount to be paid by the Owner to the Contractor.
 
ARTICLE 13    TERMINATION OR SUSPENSION

13.1 	The Contract may be terminated by the Contractor, or by the Owner for 
convenience, as provided in Article 14 of AIA Document A201-1997. However, the 
amount to be paid to the Contractor under Subparagraph 14.1.3 of A1A Document 
A201-1997 shall not exceed the amount the Contractor would be entitled to
receive under Paragraph 13.2 below, except that the Contractor's Fee shall be
calculated as if the Work had been fully completed by the Contractor, including
a reasonable estimate of the Cost of the Work for Work not actually completed. 

13.2	 The Contract may be terminated by the Owner for cause as provided in 
Article 14 of AIA Document A201-1997. The amount, if any, to be paid to the 
Contractor under Subparagraph 14.2.4 of AIA Document A201-1997 shall not cause 
the Guaranteed Maximum Price to be exceeded, nor shall it exceed an amount 
calculated as follows: 

13.2.1 	Take the Cost of the Work incurred by the Contractor to the date of 
termination; 

13.2.2 	Add the Contractor's Fee computed upon the Cost of the Work to the date 
of termination at the rate stated in Subparagraph 5.1.2 or, if the Contractor's
Fee is stated as a fixed sum in that Subparagraph, an amount that bears the
same ratio to that fixed-sum Fee as the Cost of the Work at the time of
termination bears to a reasonable estimate of the probable Cost of the Work
upon its completion; and

13.2.3 	Subtract the aggregate of previous payments made b\ the Owner. 

13.3  	The Owner shall also pay the Contractor fair compensation, either by 
purchase or rental at the election of the Owner, for any equipment owned by the 
Contractor that the Owner elects to retain and that is not otherwise included in
the Cost of the Work under Subparagraph 13.2.1. To the extent that the Owner
elects to take legal assignment of subcontracts and purchase orders (including
rental agreements), the Contractor shall, as a condition of receiving the
payments referred to in this Article 13, execute and deliver all such papers
and take all such steps, including the legal assignment of such subcontracts
and other contractual rights of the Contractor, as the Owner may require for
the purpose





<PAGE>
of fully vesting in the Owner the rights and benefits of the Contractor under
such subcontracts or purchase orders. 


13.4 	The Work may be suspended by the Owner as provided in Article 14 of 
AIA Document A201-1997; in such case, the Guaranteed Maximum Price and 
Contract Time shall be increased as provided in Subparagraph 14.3.2 of AIA 
Document A201-1997 except that the term "profit" shall be understood to mean the
Contractor's Fee as described in Subparagraphs 5.1.2 and Paragraph 6.4 of this 
Agreement.

              MECHANICAL TECHNOLOGY INCORPORATED/PLUG POWER, L.L.C.

                              LEASE FOR BUILDING 3


        THIS AGREEMENT made this 10th day of June, 1998, between Mechanical 
Technology, Incorporated, a New York corporation, as Landlord, and Plug Power, 
L.L.C., a Delaware Limited Liability company, as Tenant. 

	WITNESSETH:  The Landlord hereby leases to Tenant and Tenant hereby
hires from Landlord the building (the "Building") known as Building 3, 968
Albany-Shaker Road, Latham, New York (the "Premises") and more fully described
on the floor plan designated as Exhibit "A" attached hereto, for the term of
ten (10) years, to commence on the first day of October, 1998, and to end on the
30th day of September, 2008, unless terminated earlier, as provided below
("Term") with an option for Tenant to extend the lease for an additional five
(5) years, to commence on the first day of October, 2008, and to end on the
30th day of September, 2013 ("Option Term").

        1.  RENT.  Tenant shall pay the annual rent equal to $4.00 per square
foot ("Rent") commencing October 1, 1998 for each year during the Term.  Such
annual rent shall be made in equal monthly installments of $17,690 in advance on
or before the first day of each and every month during the Term.
 
      Tenant shall have the option to extend the lease for an additional five
years at the end of the Term.  Tenant shall pay an annual rent equal to seventy
percent (70%) of the Then-Current Fair Market Rent (as defined below) for
similar properties commencing October 1, 2008 for each year during the Option
Term.  Such annual rent shall be made in equal monthly installments  in advance
on or before the first day of each and every month during the Option Term.
The Then-Current Fair Market Rent shall be determined by a qualified real estate
professional ("Agent") agreed to by Landlord and Tenant.  If Landlord and Tenant
cannot agree upon an Agent, then each of Landlord and Tenant shall select an
Agent, each Agent shall prepare a report justifying their proposed rental rate,
and the Then-Current Fair Market Rent shall become the average of the two fair
market rental rates proposed.

      All rent shall be on a triple net basis such that this Lease shall
yield to Landlord the full amount of the installments thereof throughout the
Term and the Option Term, if applicable, without deduction.  Tenant shall be
responsible for payment of (1) the total number of square feet in Building 3,
divided by the total number of square feet of all MTI buildings ("Occupancy
Ratio") multiplied by the total property, school and other taxes payable with
respect to the buildings (less any taxes or assessment only related to the value
of the land owned by Landlord) provided, however, that if Building 3 is
reassessed (either individually or as a part of the property), such that the
total tax burden increases then, Landlord, at its option, may have the building
appraised, at its expense, and then Tenant shall be responsible for payment of
the appraisal value of Building 3 divided by the appraisal value of all MTI
buildings multiplied by the then-current assessed value of the buildings; (2)









<PAGE>
the property, school and other taxes allocated to four acres of land; (3) the
Occupancy Ratio multiplied by the sewer and water charges due or payable in
connection with the land and buildings on the MTI property; (4) all costs for
liability insurance, fire insurance, heat, air-conditioning, gas, electricity,
oil, maintenance and interior repair, janitorial services, garbage collection,
fire extinguishers, sprinkler system, building security and window cleaning of
the Premises (excluding structural defects to the roof and exterior structure
of the Building).  All rent shall be paid to Landlord without notice, demand,
counterclaim, setoff, deduction or defense, and nothing shall suspend, defer,
diminish, abate or reduce any rent, except as otherwise specifically provided
in this Lease. 

        2.  LANDLORD DUTIES.  Landlord at its sole cost and expense shall be
responsible for the following:  cleaning and maintenance of common areas, snow
removal, cleaning and maintenance of roadway, walks, and parking areas and the
care and maintenance of landscaping and grounds.  As used in this Lease, the
term "common areas" means driveways, walkways, trash facilities, and all other
areas and facilities that are provided and designated from time to time by
Landlord for the general nonexclusive use and convenience of Tenant with
Landlord and other Tenants and their respective employees, invitees, licensees,
or other visitors. Landlord grants Tenant, its employees, invitees, licensees
and other visitors a nonexclusive license for the Term to use the common areas
in common with others entitled to use the common areas, subject to the terms
and conditions of this Lease.  Without advance written notice to Tenant, and
without any liability to Tenant in any respect, provided Landlord will take no
action permitted under this paragraph in such a manner as to materially impair
or adversely affect Tenant's substantial benefit and enjoyment of the Premises,
Landlord will have the right to: 
 
        1)   Temporarily close any of the common areas for 
        maintenance, alteration or improvement purposes; and 

        2)   Change the size, use, shape or nature of any such
        common areas, so long as it does not materially interfere
        or adversely impact Tenant's business.

Landlord, at its sole cost and expense, shall be responsible for the care and 
maintenance of 1) the exterior of the building and 2) the roof, plumbing and
electricity on the non-laboratory side of the fire wall.  Provided, however,
that Landlord shall not be responsible for any maintenance that is due to the
negligence or neglect of Tenant.

        3.  OBLIGATION OF LANDLORD REGARDING IMPROVEMENTS.  Landlord shall 
have the following obligations with respect to alterations and improvements of
the Premises that are necessary to the operation of Tenant's business.














<PAGE>
              (a)     Landlord shall provide to Tenant the amount of $2,000,000
as a "Tenant Improvement Allowance" which shall be drawn down by Landlord from
an IDA facility, as needed to reimburse Tenant for alterations and improvements
to the Premises in a manner as more fully set forth below.
 
              (b)     Landlord acknowledges that Tenant has heretofore made
certain alterations and improvements to the Premises that are necessary to the
operation of Tenant's business, and that Tenant has paid the amount of
approximately $800,000 to make such alterations and improvements and Tenant
shall continue to make alterations and improvements to the property.  Landlord
agrees to reimburse or advance such funds to Tenant out of the Tenant
Improvements Allowance for such alterations and improvements on or before the
first to occur of i) funding of Landlord's IDA financing ("Lender") for the
project; ii) cash flow need by Tenant as determined by Tenant in its sole
discretion, after July 15, 1998, or iii) August 15, 1998.
 
              (c)     Landlord further agrees to reimburse or advance such funds
to Tenant out of the Tenant Improvements Allowance for additional alterations
and improvements to the Premises that are necessary to the operation of Tenant's
business and acceptable to Tenant on or before March 31, 1999 or such later date
as may be approved by Tenant.  Tenant shall be solely responsible for
determining what alterations and improvements it deems necessary to the
operation of its business and shall be solely responsible for arranging such
alterations and improvements, including the hiring of appropriate contractors to
perform the work.  With respect to of any aspect of such work, Tenant shall have
its architect or builder prepare a requisition in the form required by the AIA
form ("Requisition") and such other documentation as required by Landlord's
Lender to Landlord, and Landlord shall reimburse Tenant upon funding to Landlord
by its Lender for the work.  All reimbursements shall be made within 10 business
days of approval of the Requisition by Lender. The parties acknowledge and agree
that Landlord's total financial responsibility for all alterations and
improvements relating specifically to Tenant's business shall not exceed the
amount of $2,000,000, which amount includes the reimbursement amount of $800,000
or such larger amount provided for in subsection (a) above.
 
              (d)     Tenant shall be entitled to offset any unreimbursed amount
against the rent due under this Lease if any invoiced amount is funded by Lender
and not paid by Landlord to Tenant within 10 business days of such invoice.

Tenant alterations and improvements must be done in good, workmanlike and
orderly fashion, and shall be of such nature that as not to affect the safety

or improvements to the roof that are inconsistent with or void Landlord's
warranty for the roof.  Landlord's warranty shall permit the use of multiple

without disturbance, molestation or injury, with the exception that any such
alterations, improvements, additions, partitions, or trade fixtures which
relate specifically to Tenant's business may be removed from the Premises by
Tenant upon termination of the Lease, provided that Tenant can accomplish such 
removal without damage to the Premises.













<PAGE>
     Subject to all other terms of this Lease, Tenant shall take good care of
the Premises and fixtures, make good any injury or breakage done by Tenant or
Tenant's agents, employees or visitors, and shall quit and surrender the
Premises, at the end of the Term, or the Option Term (as applicable) in as good
condition as the reasonable use thereof will permit.
 
        8.   ASSIGNMENT.  Tenant, successors, heirs, executors or administrators
shall not assign this agreement, or underlet or underlease the Premises, or any
part thereof, without Landlord's prior consent in writing.  Notwithstanding any
such permitted sublease, Tenant shall remain fully and primarily liable for the

covenants and conditions contained in this Lease Agreement, jointly and
severally with such assignee or sublessee.  Tenant shall not occupy, or permit
or suffer the Premises to be occupied for any business or purpose deemed
disreputable or extra-hazardous, under the penalty of damages and forfeiture,
and in the event of a breach thereof, the Term herein shall immediately cease
and determine at the option of Landlord as if it were the expiration of the
original Term.
 
        9.   SIGNS.  No sign, advertisement, notice or other lettering shall be
exhibited, inscribed, painted or affixed by Tenant on any part of the Premises
or Building without the prior written approval and consent of Landlord, which

Default" under this Lease: 

              (a)     any failure of Tenant to pay any rent when due and such
failure continues uncured for fifteen (15) days after Landlord gives Tenant
notice of such failure;

              (b)     any failure of Tenant to perform any other of the terms,
conditions or covenants of this Lease to be performed by Tenant and such failure
continues uncured for thirty (30) days after written notice from Landlord
specifying such failure, except that in cases where Tenant cannot reasonably
cure within said thirty (30) day period, only if Tenant fails to commence to
cure within such thirty (30) day period and thereafter to diligently continue
to cure the same until fully corrected; and












<PAGE>
              (c)     if both (i) Tenant's estate created by this Lease shall
be taken upon execution, attachment or other process of law, and any such
execution, attachment or other process be not vacated or set aside within thirty
(30) days thereafter, or if Tenant shall be adjudged as bankrupt, or if Tenant
shall file a voluntary petition in bankruptcy, or if an involuntary petition in
bankruptcy be filed and not vacated or set aside within ninety (90) days
thereafter, and (ii) there otherwise occurs an Event of Default as specified in
subparagraphs "(a)" and "(b)" above.
 
        11.   REMEDIES.  Upon an event of Default, Landlord may immediately, or
at any time thereafter, re-enter the Premises and remove all persons and all or
any property therefrom, either by summary dispossess proceedings, or by any
suitable action or proceeding at law, and repossess and enjoy the Premises
together with all additions, alterations and improvements.  In any such case,
Landlord may either relet the Premises or any part or parts thereof for
Landlord's own account, or may at Landlord's option, relet the Premises or any
part or parts thereof, as the agent of Tenant, and receive the Rents therefor,
applying the same first to the payment of such expenses as Landlord may have
incurred, and then to the fulfillment of the covenants of Tenant herein, and
the balance, if any, at the expiration of the Term, shall be paid to Tenant.
In the event that the Term shall terminate by summary proceedings or otherwise,
and if Landlord shall not relet the Premises for Landlord's own account, then,
whether or not the Premises be relet, Tenant shall remain liable for, and Tenant
hereby agrees to pay to Landlord, until the time when this Lease would have
expired but for such termination or expiration, the equivalent of the amount
of all of the Rent and "additional Rent" reserved herein, less the avails of
reletting, if any, and the same shall be due and payable by Tenant to Landlord
on the several Rent days above specified; that is, upon each of such Rent days
Tenant shall pay to Landlord the amount of deficiency then existing.  Tenant
hereby expressly waives any and all right of redemption in case Tenant shall
be dispossessed by judgment or warrant of any court or judge, and Tenant waives
and will waive all right to trial by jury in any summary proceedings hereafter
instituted by Landlord against Tenant in respect to the Premises or any action
to recover Rent or damages hereunder.
 
        12.   ACCESS TO PREMISES.  Tenant agrees that Landlord and Landlord's
agents and other representatives shall have the right to enter into and upon
the Premises, or any part thereof, at all reasonable hours and upon twenty-four
(24) hours reasonable notice (except in the case of emergencies) for the purpose
of examining the same, or for making such repairs, alterations, additions, or
improvements therein as may be necessary or deemed advisable by Landlord. 
 
        13.   ADDITIONAL BUILDINGS.  Landlord acknowledges that Tenant may
desire to construct a manufacturing facility on the land upon which the Premises
is located. Landlord agrees to enter into good faith negotiations with Tenant
with respect to Landlord's construction of such building or Landlord's land for
use and occupancy by Tenant as a manufacturing facility, or, alternatively, a
long-term ground lease permitting Tenant's construction of such a facility,
provided, that Landlord's obligation to enter such negotiation shall be
contingent upon Tenant providing evidence of the availability of financing such
a project.








<PAGE>
        14.   TENANT'S RIGHT OF FIRST REFUSAL.  If (i) Landlord receives a bona
fide offer for the lease of all or any portion of the first floor of Building 2
not then leased by Tenant or Foster-Miller Technologies, Inc. (the "Space"), or
(ii) Landlord desires to offer the space for lease, Landlord shall give Tenant
the right of first refusal to lease the space, at the rent and on the terms and
conditions of the offer, in accordance with the following:
 
              (a)     The right of first refusal will be extended by Landlord
giving Tenant written notice of the particular offer received or made by
Landlord, together with a detailed summary of the offer, requiring Tenant to
sign an appropriate amendment to this Lease subjecting the space to this Lease
at the rent and for the term set forth in the offer, within 30 days after the
mailing of such notice.

              (b)     In a case arising under clause (i) above of this
paragraph, if Tenant does not sign an amendment to this Lease for the space
within the 30-day period, Landlord will have the right to accept the offer
received free of the rights of Tenant under this paragraph, except as stated
in subparagraph (d) of this paragraph.
 
              (c)     In a case arising under clause (ii) above of this
paragraph, if Tenant fails to accept or rejects the offer within the 30-day
period, Landlord will be entitled for a period of 180 days to lease the space
on the same terms stated in the notice to Tenant. If Landlord does lease the
space during the 180-day period, the right granted Tenant under this paragraph
will automatically terminate, except as stated in subparagraph (d) of this
paragraph.
 
              (d)     If Landlord does not lease the space pursuant to
subparagraph (b) above strictly in accordance with the offer presented to, and
rejected by, Tenant, or does not lease the space during the 180-day period
referred to in subparagraph (c) above, or if upon leasing the space to a third
party, such lease terminates or the space becomes vacant while this Lease is
still in force, Landlord may not subsequently lease the space without Landlord's
compliance with this paragraph.  Tenant's right of first refusal to lease the
space will continue throughout the term of this Lease with respect to any space
available for lease from time to time.
 
              (e)     Any space leased by Tenant will be added to the Premises
as of the date provided in the offer, and the Rent will be adjusted to reflect
the rent provided to be paid in accordance with the offer.  Tenant shall execute
amendments to this Lease to reflect additions to the Premises resulting from the
exercise of this right of first refusal to lease.  Tenant's lease of any space
















<PAGE>
pursuant to this right of first refusal will be on all the terms and conditions
set forth in this Lease except as to rent, which will be that set forth in the
offer.  Except as stated in this Section, Landlord is under no obligation to
offer for lease all or any portion of the space to Tenant or any other person.
 
        15.   INABILITY TO PERFORM.  Except as set forth herein, this Lease and
the obligation of Tenant to pay Rent hereunder and perform all of the other
covenants and agreements hereunder on part of Tenant to be performed shall in
no way be affected, impaired or excused because Landlord is unable to supply or
is delayed in supplying any service expressly or impliedly to be supplied or is
unable to make, or is delayed in making any repairs, additions, alterations or
decorations or is unable to supply or is delayed in supplying any equipment or
fixtures or Landlord is prevented or delayed from so doing, by reason of
governmental preemption in connection with any National Emergency declared by
the President of the United States or in connection with any rule, order or
regulation of any department or subdivision thereof of any governmental agency
or by reason of the condition of supply and demand which have been or are
affected by war or other emergency.
 
        16.   DESTRUCTION.  In the case of damage, by fire or other action of
the elements, to the Building, without the fault of Tenant or of Tenant's agents
or employees, if the damage is so extensive as to amount practically to the
total destruction of the Premises or of the Building, or if Landlord shall
within a reasonable time decide not to rebuild, this Lease shall cease and come
to an end, and the Rent shall be apportioned to the time of the damage.  In all
other cases where the Premises are damaged by fire without the fault of Tenant
or of Tenant's agents or employees, Landlord promptly shall repair the damage
after notice of damage, and if the damage has rendered the Premises
untenantable, in whole or in part, there shall be an apportionment of the Rent
until the damage has been repaired.  Consideration shall be given to delays
caused by strikes, adjustment of insurance and other causes beyond Landlord's
control.  Landlord is not required to repair or replace any equipment,
fixtures, furnishings or decorations, unless originally installed by Landlord. 
 
        If the fire or other casualty is caused by an act or negligence of
Tenant, Tenant's employees or invitees, then all repairs will be made at
Tenant's expense and Tenant must pay the full rent with no adjustment.  The cost
of the repairs will be added rent.
 
       Landlord has the right to demolish or rebuild the Building if there is
substantial damage by fire or other casualty.  Landlord or Tenant may cancel
this Lease within 30 days after the substantial fire or casualty by giving
Landlord/Tenant notice of Landlord's/Tenant's intention to demolish or rebuild.
The Lease will end 30 days after Landlord's/Tenant's cancellation notice to
Landlord/Tenant.  Tenant must deliver the Premises to Landlord on or before the
cancellation date in the notice and pay all Rent due to the date of the fire or
casualty.  If the Lease is canceled, Landlord is not required to repair the
Premises or Building. The cancellation does not release the Tenant or Landlord











<PAGE>
of liability in connection with the fire or casualty. This section is intended
to replace the terms of New York Real Property Law Section 227. 
 
        17.   CONDEMNATION.  Should the land whereon all or part of the Building
stands be condemned for public use, then in that event, upon the taking of the
same for such public use, this Lease shall become null and void, and the Term
shall cease and come to an end upon the date when the same shall be taken and
the Rent and all other charges shall be apportioned as of said date.  Tenant
shall have no claim against Landlord for the value of any unexpired Term of
this Lease.  No part of any award, however, shall belong to Tenant, except as
permitted by law.
 
        18.   LIABILITY.  Landlord is exempt from any and all liability for any
damage or injury to person or property caused by or resulting from steam,
electricity, gas, water, rain, ice or snow, or any leak or flow from or into any
part of said Building or from any damage or injury resulting or arising from any
other cause or happening whatsoever unless said damage or injury be caused by or
be due to the negligence of Landlord.
 
        19.   INDEMNIFICATION.  Except for any injury or damage to persons or
property on the Premises that is caused by or results from the negligence or
deliberate act of Landlord, its employees or agents, and subject to the
provisions of paragraph 19, Tenant will not hold Landlord, its employees or
agents liable for, and Tenant will indemnify and hold harmless Landlord, its
employees and agents from and against any and all demands, claims, causes of
action, fines, penalties, damages (including consequential damages),
liabilities, judgments and expenses (including without limitation reasonable
attorneys' fees) incurred in connection with or arising from:
 

        1)    the use or occupancy or manner of use or occupancy of the  
              Premises by Tenant or any person claiming under Tenant;
   
        2)    any activity, work or thing done or permitted by Tenant in or
              about the Premises, the Building or the Project;

        3)    any breach by Tenant or its employees, agents, contractors or 
              invitees of this Lease; and

        4)    any injury or damage to the person, property or business of
              Tenant, its employees, agents, contractors or invitees entering
              upon the Premises under the express or implied invitation of
              Tenant.

       	If any action or proceeding is brought against Landlord, its employees
or agents by reason of any such claim for which Tenant has indemnified Landlord,
Tenant, upon written notice from Landlord, will defend the same at Tenant's
expense, with counsel 











<PAGE>
reasonably satisfactory to Landlord.

        20.   TENANT'S INSURANCE.  At all times during the Term, Tenant will
carry and maintain, at Tenant's expense, the following insurance, in the amounts
specified below or such other amounts as Landlord may from time to time
reasonably request, with insurance companies and on forms satisfactory to
Landlord:
 
        1)     Bodily injury and property damage liability insurance,
               with a combined single occurrence limit of not less than
               $3,000,000 or the appraised value of the Premises, whichever is
               greater.  All such insurance will be equivalent to coverage
               offered by a commercial general liability form, including without
               limitation personal injury and contractual liability coverage
               for the performance by Tenant of the indemnity agreements set
               forth in this Lease;

        2)     Workers' compensation insurance satisfying Tenant's
               obligations and liabilities under the workers' compensation
               laws of the State of New York, including employer's liability
               insurance in the limits required by the laws of the State of New
               York; and

        3)     If Tenant operates owned, hired or non-owned vehicles on
               the project, comprehensive automobile liability at a limit of
               liability not less than $500,000 combined bodily injury and
               property damage. 


	Certificate of insurance, naming the Landlord as additional insured,
will be delivered to the Landlord prior to the Tenant's occupancy of the
Premises.  All commercial general liability or comparable policies maintained
by Tenant will name Landlord as additional insured.  All commercial general
liability and property policies maintained by Tenant will be written as primary
policies, not contributing with and supplemental to the coverage that the
Landlord may carry.

        21.   LIABILITY INSURANCE.  Tenant shall carry public liability
insurance in the amount of One Million Dollars ($ 1,000,000) per person -- Two
Million Dollars ($2,000,000) per occurrence covering the Premises and shall name
Landlord as an additional insured therein and shall furnish to Landlord a
certificate of said insurance.
 
        22.   WAIVER OF CLAIMS AND SUBROGATION.  Landlord shall be exempt from, 
and the Tenant agrees to accept the risk of loss by fire or other casualty
covered by insurance as to the contents, leasehold improvements or fixtures of
the Premises ensuing by reason of fire or other casualty covered by insurance.
Tenant shall be exempt from, and Landlord agrees to accept the risk of loss by
fire or other casualty covered by insurance as to the building, equipment,










<PAGE>
fixtures and appurtenances of the Premises during the Term or any renewal
thereof. Landlord and Tenant shall each cause each insurance policy carried by
each respectively, insuring the Building or the Premises, its contents,
Leasehold improvements or fixtures, to be written in a manner so as to provide
that the insurance companies waive all right or recovery by way of
subrogation against the other party in connection with any loss or damage
covered by any such policies. 
 
        23.   NO WAIVER.  The failure of Landlord or Tenant to insist upon a
strict performance of any of the Terms, conditions and covenants herein, shall
not be deemed a waiver of any rights or remedies that Landlord or Tenant may
have, and shall not be deemed a waiver of any subsequent breach or default in
the Terms, conditions and covenants herein contained. This instrument may not
be changed, modified or discharged orally. 
 
        24.   SUBORDINATION.  This instrument shall not be a lien against the
Premises in respect to any bank, insurance company or other lending institution
mortgages that are now on or that hereafter may be placed against the Premises,
and that the recording of such mortgage or mortgages shall have preference and
precedence and be superior and prior in lien of this Lease, irrespective of the
date of recording and Tenant agrees to execute any such instrument without cost,
that maybe reasonably necessary or desirable to further effect the subordination
of this Lease to any such mortgage or mortgages, provided any such mortgagee
shall first execute and deliver to Tenant a nondisturbance agreement in a form
reasonably satisfactory to Tenant, by which the mortgagee agrees not to cut off
this Lease in foreclosure.  Tenant's refusal to execute such instrument shall
entitle Landlord, or Landlord's assigns and legal representatives, to cancel
this Lease without incurring any expense or damage and the Term hereby granted
is expressly limited accordingly.
 
        25.   ESTOPPEL CERTIFICATE.  Tenant shall from time to time, upon
Landlord's reasonable request, deliver a written instrument ("Estoppel
Certificate") to Landlord or to any other person or firm specified by Landlord,
duly executed and acknowledged, certifying to the best of its knowledge,
information or belief that this Lease is unmodified and in full force and
effect or, if there has been any modification, that the Lease is in full force
and effect as modified, and stating any and all such modifications; specifying
the dates to which Rent and additional rent provided for herein have been paid,
and whether there exists any default in the performance of any covenant
agreement, term, provision or condition contained in this Lease. 
 
        26.   QUIET ENJOYMENT.  Tenant, upon payment of the rent, additional
rent and other required charges, and the performance by Tenant under this Lease,
shall have the peaceful and quiet enjoyment of the Premises without hindrance
or disturbance by Landlord or those claiming by, through or under Landlord, or
any other person or entity whatsoever. 













<PAGE>
        27.   LATE CHARGES.  A late charge of five (5%) percent shall be
assessed to any rental payment not made within fifteen (15) days of the due
date and shall be considered additional rent. 
 
        28.   NOTICES.  Any notice given Tenant shall be in writing and sent by
registered or certified mail to Tenant at: 
 
             Plug Power, L.L.C.
             968 Albany-Shaker Road
             Latham, New York 12110
 
Tenant may change the address at which notices shall be given at any time by
like notice to Landlord. Any notices to be given Landlord shall be given in

             Mechanical Technology, Incorporated
             968 Albany-Shaker Road
             Latham, New York 12110

Landlord may change the address at which notices shall be given any time by like
notice to Tenant. 

        29.   ATTACHMENTS TO LEASE.  The covenants and agreements in the Lease, 
addendums, exhibits and attachments shall be binding upon the parties hereto
and upon their respective successors, heirs, executors and administrators. 
 
        30.   MISCELLANEOUS. Notwithstanding anything to the contrary contained
in this Lease, any monies due Landlord under this Lease in addition to the rent
shall be deemed to be additional rent. Any default on the payment of such
additional rent shall give Landlord the same rights and remedies as are provided
herein with respect to a default in the payment of rent.  Tenant's obligations
to pay rent and additional rent shall survive the expiration of the Term, or the
Optional Term, or earlier termination of this Lease. 
 
        The failure of Landlord or Tenant to insist upon a strict
performance of any term, covenant or condition herein shall not be deemed
a waiver of any rights or remedies that Landlord or Tenant may have or a waiver
of any subsequent breach or default.
 
        If any provision of this Lease shall be unenforceable or invalid, such 
unenforceability or invalidity shall not affect any other provision of this
Lease.

	IN WITNESS WHEREOF, Landlord and Tenant respectively have signed and 
sealed this Lease as of the day and year first above written.
