PART I


ITEM 1:  BUSINESS

MTI manufactures and sells precision diagnostic and measurement
instruments and incubates alternative energy technology.   Given MTI's
recent success with Plug Power, Inc. and its early development efforts
with Proton Exchange Membrane ("PEM") fuel cells, gas and steam powered
turbines and the Sterling Engines, MTI is in a unique position to be a
leader in the evolution of alternative energy technology.  MTI's
alternate energy strategy includes: acquisition of companies that have
synergies with MTI's core competencies; acquisition of majority stock
positions in established alternative energy companies; and internal
development and growth of alternative energy businesses.

Over the last several years MTI sold off non-core businesses and
restructured its balance sheet.  Today MTI is a very different company,
substantially streamlined in focus, but with challenges remaining. MTI
is a manufacturer of advanced diagnostic, test and measurement products
that combine precision sensing capabilities with proprietary software
and systems to serve a variety of applications for commercial and
military customers.  The Company has two principal business units: the
Advanced Products Division ("Advanced Products"), which produces
diagnostic and sensing instruments and computer-based balancing systems;
and Ling Electronics, Inc. ("Ling"), a developer and manufacturer of
vibration test systems and power conversion products, which was sold on
October 21, 1999, as part of a strategic alliance with SatCon Technology
Corporation.

In the coming year, Advanced Products will focus on improving existing
products and developing additional products for diagnostic and testing
equipment.  The non-contact sensing instrumentation products utilize
fiber optic, laser and capacitance technology to perform high precision
position measurements for product design and quality control inspection
requirements, primarily in the semiconductor and computer disk drive
industries.  Advanced Products' computer-based aircraft engine balancing
systems include an on-wing jet engine balancing system used by both
commercial and military aircraft fleet maintenance personnel.  This
product provides trim balancing and vibration analysis in the field or
in test cells.

MTI is uniquely positioned to be the moving force behind the evolution
of alternative energy technology.  As a pioneer in the alternative
energy field, MTI has demonstrated its ability, first in the research
and development of gas and steam turbines; then through its development
efforts in connection with the Sterling Engines; and most recently in
its research and development of PEM fuel cell technology.  MTI has
successfully turned its PEM fuel cell research into a public company
dedicated to bringing a safe, reliable and cost-effective fuel cell to
market.  Plug Power, Inc., which was initially a joint venture of MTI
and Detroit Edison, believes that it will soon have residential fuel
cells in the market place.  MTI helped develop the strategic
partnerships, capital investment, and growth strategy of Plug Power,
Inc.  It is MTI's forward strategy to use its resources and experiences
to repeat this success with other alternative energy companies.

<PAGE>

Mechanical Technology Incorporated was incorporated in New York in 1961.
Unless the context otherwise requires, the "registrant", "Company",
"Mechanical Technology" and "MTI" refers to Mechanical Technology
Incorporated and its subsidiaries.  The Company's principal executive
offices are located at 325 Washington Avenue Extension, Albany, New York
12205 and its telephone number is (518) 218-2500.


Significant Developments in the Business

On June 27, 1997, the Company and Edison Development Corp. ("EDC"), a
subsidiary of DTE Energy Co. formed a joint venture, Plug Power, L.L.C.
("Plug Power"), to further develop the Company's Proton Exchange Membrane
("PEM") Fuel Cell technology. In exchange for its contribution of
contracts and intellectual property and certain other net assets that had
comprised the fuel cell research and development business activity of the
Technology segment (which assets had a net book value of $357 thousand),
the Company received a 50% interest in Plug Power.  EDC made an initial
cash contribution of $4.75 million in exchange for the remaining 50%
interest in Plug Power. The Company's investment in Plug Power is included
in the balance sheet caption "Investment in Plug Power"; the assets
contributed by the Company to Plug Power had previously been included in
the assets of the Company's Technology segment. See the supplemental
disclosure regarding Contribution of Net Assets to Plug Power in the
Consolidated Statements of Cash Flows for additional information regarding
the assets contributed by the Company to Plug Power.

Plug Power has focused exclusively on the research, development and
manufacture of an economically viable PEM fuel cell. During 1999, the
Company invested $6 million cash in Plug Power and sold the MTI campus
to Plug Power in exchange for shares of Plug Power and Plug Power's
assumption of $6 million of debt.

On October 29, 1999 Plug Power Inc. made an initial public offering
("IPO") of its common stock on the NASDAQ National Market under the
symbol "PLUG."  The initial public offering price for the 6 million
shares issued was $15 per share.  Additionally, the underwriters of the
IPO exercised their 900,000 share over allotment at the IPO price.

Since Plug Power was formed in 1997 the Company, EDC and other investors
have contributed substantial amounts of cash and other assets to Plug
Power.  Contributions to Plug Power by the Company totaled $20.7 million
as of September 30, 1999. Immediately prior to the Plug Power IPO, the
Company purchased an additional 2,733,333 shares of Plug Power at $7.50
per share for a total purchase price of $20.5 million.  Immediately
after Plug Power's IPO, the Company owned 13,704,315 shares of Plug
Power or approximately 31.9 percent of outstanding Plug Power stock.
The Company's contribution to Plug Power increased to $41.2 million as
of Plug Power's IPO date.

On October 21, 1999, the Company created a strategic alliance with
SatCon Technology Corporation (SatCon), an innovator of alternative
energy technologies.  SatCon acquired Ling Electronics, Inc. and Ling
Electronics, Ltd. from the Company and the Company committed to invest
approximately $7 million in SatCon.  In consideration for the
acquisition of Ling Electronics and the Company's investment, the
Company will receive 1,800,000 shares of SatCon's common stock and

<PAGE>

warrants to purchase an additional 100,000 shares of SatCon's common
stock.  The Company funded $2.57 million of its investment in SatCon and
will make the remaining investment by the end of January 2000.  SatCon
will also receive warrants to purchase 100,000 shares of the Company's
common stock.

On July 12, 1999, the Company completed the sale of 801,223 shares of
common stock to current shareholders through a rights offering.  The
offering raised approximately $12.8 million before offering costs of
approximately $158 thousand for net proceeds of approximately $12.7
million.  The Company will use some or all of the proceeds of the offering
for investment into Plug Power.  In addition, some proceeds may be used
for acquisitions, efforts to increase market share, working capital,
general corporate purposes and other capital expenditures.

On September 30, 1998, the Company completed the sale of 1,196,399 shares
of common stock to current shareholders through a rights offering.  The
offering raised approximately $7.2 million before offering costs of
approximately $186 thousand for net proceeds of approximately $7 million.
The Company used substantially all of the proceeds of the offering for
investment in Plug Power.  The remaining proceeds were used for efforts to
increase market share, working capital, general corporate purposes and
other capital expenditures.

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.  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 the net assets and operating results of the business. The
Company's prior year financial statements have been restated to conform
to this treatment.  See Note 16 to the accompanying Consolidated
Financial Statements.

On September 30, 1997, the Company sold all of the assets of its L.A.B.
division to Noonan Machine Company of Franklin Park, IL.  The Company
received $2.6 million in cash and two notes, totaling $650 thousand, from
Noonan Machine Company.  The purchaser has requested that the principal
amount of the note be reduced to reflect the resale value of certain
assets of L.A.B.  The Company is enforcing its rights with respect to the
note.  The net proceeds from the sale were used to pay down all
outstanding debt and build working capital.  The sale of L.A.B. resulted
in a $2.0 million gain, which was recorded in the fourth quarter of fiscal
year 1997.

On December 27, 1996, the Company and First Albany Companies Inc. ("FAC")
entered into a Settlement Agreement and Release whereby the Company issued
FAC 1.0 million shares of Common Stock in full satisfaction of its
obligations pursuant to the Claim Participation Agreement dated December
21, 1993 and amended December 14, 1994, among United Telecontrol
Electronics, Inc. ("UTE"), the Company and First Commercial Credit

<PAGE>

Corporation, in the principal amount of $3.0 million plus accrued interest
of $1.2 million. As a result, the Company in the first quarter of fiscal
1997 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.


Business Segments

The Company currently conducts business in two business segments:
Alternative Energy Technology and Test and Measurement.


Alternative Energy Technology

The Alternative Energy Technology segment incubates companies that
research, develop, manufacture and distribute alternative energy
technology solutions. Investments at September 30, 1999 consist of a 40.65
percent equity interest in Plug Power L.L.C.  Plug Power is a leading
designer and developer of on-site, electricity generation systems
utilizing proton exchange membrane ("PEM") fuel cells for residential
applications.  GE Fuel Cell Systems, LLC, a joint venture that is owned by
General Electric's GE Power Systems business (75%) and Plug Power (25%)
will market, sell, service, and install Plug Power's products once they
are developed.

On October 29, 1999 Plug Power Inc. made an initial public offering
("IPO") of its common stock on the NASDAQ National Market under the
symbol "PLUG."  The initial public offering price for the 6 million
shares issued was $15 per share.

Immediately prior to the Plug Power IPO, the Company purchased an
additional 2,733,333 shares of Plug Power at $7.50 per share for a total
purchase price of $20.5 million.  The Company financed the acquisition
of these shares through a $22.5 million loan from KeyBank N.A.
Immediately after Plug Power's IPO, the Company owned 13,704,315 shares
of Plug Power or approximately 31.9 percent of outstanding Plug Power
stock.

Plug Power is developing a PEM fuel cell for residential and automotive
applications.  As of December 1999, Plug Power has reported achieving
the following milestones:

June 1998               Powered a three-bedroom home ("Demonstration Home")
                        with a hydrogen-fueled residential fuel cell system

                        York

August 1999		Powered the Demonstration Home with a residential
                        fuel cell system connected to its existing natural
                        gas pipeline

September 1999		Filed their 50th patent application relating to fuel
                        cell technology, system designs and manufacturing
                        processes

December 1999		Announced successful completion of a four-month test
                        of a natural gas powered fuel cell system in the
                        Demonstration Home

In October, 1999, MTI sold Ling to SatCon in exchange for common stock and
purchased or made commitments to purchase SatCon common stock and
warrants.  Assuming all funding commitments are made and warrants
exercised, MTI will own approximately 16% of SatCon's issued and
outstanding common stock.

SatCon manufactures and sells power and energy management products for
telecommunications, silicon wafer manufacturing, factory automation,
aircraft, satellites and automotive applications.  SatCon has four
operating divisions:  Film Microelectronics, Inc. designs and manufactures
microelectronic circuits and interconnect products;  Magmotor manufactures
motors and magnetic suspension systems;  Beacon Power manufactures
flywheel energy storage devices;  and the Technology Center is responsible
for new technology and product development.

Test and Measurement

Test and Measurement offers a wide range of technology-based equipment and
systems for improved manufacturing, product testing, and inspection for
industry.  Business units in this segment include the Advanced Products
Division, Ling Electronics, Inc. (sold on October 21, 1999) and the L.A.B.
Division (sold on September 30, 1997).

Advanced Products designs, manufactures and markets high-performance test
and measurement instruments and systems.  These products are categorized
in two general product families: non-contact sensing instrumentation and
computer-based balancing systems.  The Division's largest customers
include industry leaders in the computer, electronic, semiconductor,
automotive, aerospace, aircraft and bioengineering fields.

<PAGE>

The non-contact sensing instrumentation products utilize fiber optic,
laser and capacitance technology to perform high precision position
measurements for product design and quality control inspection
requirements, primarily in the semiconductor and computer disk drive
industries.  Product trademarks such as the Fotonic Sensor and Accumeasure
are recognized worldwide.

The Division's computer-based aircraft engine balancing systems include an
on-wing jet engine balancing system used by both commercial and military
aircraft fleet maintenance personnel.  This product provides trim
balancing and vibration analysis in the field or in test cells.

Ling, of Anaheim, California, designs, manufactures, and markets
electro-dynamic vibration test systems, high-intensity-sound
transducers, power conversion equipment and power amplifiers used to
perform reliability testing and stress screening during product
development and quality control. This mode of testing is used by
industry and the military to reveal design and manufacturing flaws in a
broad range of precision products, from satellite parts to computer
components.  Recent Ling products for power and frequency conversion and
"clean power" applications include systems capable of output up to 432
kVA.  Ling was sold on October 21, 1999 to SatCon in exchange for
770,000 shares of SatCon common stock (with a market value of $6.738
million on the transaction date).

The L.A.B. Division, which was sold on September 30, 1997, designed,
manufactured and marketed mechanically driven and hydraulically driven
test systems for package and product reliability testing.  Among other
uses, this equipment simulates the conditions a product will encounter
during transportation and distribution including shock, compression,
vibration and impact.  This type of testing is widely conducted by
businesses involved in product design, packaging and distribution.

The Company believes that the test and measurement industry will undergo
substantial consolidation in the near future.  The challenges facing MTI
today are similar to those facing other smaller companies in industries
where consolidation is a part of the landscape.  The Company believes
that consolidation may become a competitive necessity and that Advanced
Products is well-positioned to combine with complementary, synergistic
businesses to enhance and expand product offerings and increase
profitability and market position.  Accordingly, the Company is actively
exploring strategic acquisitions and alliances for its businesses.

The business units in the Test and Measurement segment have numerous
customers and are not dependent upon a single or a few customers.


Backlog

The backlog of orders believed to be firm as of September 30, is $2.1
million for 1999 and 1998 (of which $997 thousand and $487 thousand,
respectively, relates to the Company's Advanced Products Division).  The
backlog relates to contracts awarded by commercial customers or government
agencies.

<PAGE>

Marketing and Sales

The Company sells its products and services through a combination of a
direct sales force, manufacturer's representatives, distributors and
commission salespeople.  Each business unit is responsible for its own
sales organization. Typically, the Company's product businesses employ
regional manufacturer's representatives on an exclusive geographic basis
to form a nationwide or worldwide distribution organization; the business
unit is responsible for marketing and sales management and provides the
representatives with sales and technical expertise on an "as-required"
basis. To a great extent, the marketing and sales of the Company's larger
products and systems consist of a joint effort by the business unit's
senior management, its direct sales force and manufacturer's
representatives to sophisticated customers.  The manufacturer's
representatives are compensated on a commission basis.


Research and Development

The Company conducts considerable research and development to support
existing products and develop new products.  (See the accompanying
Consolidated Statements of Operations).  The Company holds patents and
rights in various fields of technology.  The technology of the Company is
generally an advancement of the "state of the art", and the Company
expects to maintain a competitive position by continuing such advances
rather than relying on patents.  Licenses to other companies to use
Company-developed technology have been granted and are expected to be of
benefit to the Company, though royalty income received in recent years has
not been material in amount and is not expected to be material in the
foreseeable future.


Competition

The Company and each of its business units are subject to intense
competition. The Company faces competition from at least several
companies, many of which are larger than MTI and have greater financial
resources.  While the business units in the Company's Test and Measurement
segment each have a major share of their respective markets, the Company
does not consider any of them to be dominant within its industry.

The primary competitive considerations in the test and measurement segment
are product quality and performance, price and timely delivery. The
Company believes that its product development skills and reputation are
competitive advantages.


Employees

The total number of employees of the Company and its subsidiaries was 104
as of September 30, 1999, compared to 123 as of the beginning of the
fiscal year.

ITEM 2:  PROPERTIES

The Company leases property in New York and, prior to the sale of Ling,
leased space in California.  In management's opinion, the facilities are
generally well-maintained and adequate to meet the Company's current and
future needs.

The Company's corporate headquarters were located in a building in Latham,
New York which was sold to Plug Power during 1999 and a portion of which was
leased back to the Company until November 1999.  The building contained a
total of approximately 31,000 square feet.  In November 1999, the Company

<PAGE>

completed its relocation to Albany, New York, where it leases a facility for
Advanced Products and corporate headquarters.  The facility has approximately
20,700 square feet of office and manufacturing space.  The lease expires on
November 30, 2009.

Ling Electronics, Inc. (Ling) leases approximately 85,000 square feet of
office and manufacturing space in Anaheim, California.  The lease will
expire in June of 2003.  Ling was sold, and the lease assigned, to SatCon
Technology Corporation on October 21, 1999.


ITEM 3:  LEGAL PROCEEDINGS

At any point in time, the Company and its subsidiaries may be involved in
various lawsuits or other legal proceedings; these could arise from the
sale of products or services or from other matters relating to its regular
business activities, may relate to compliance with various governmental
regulations and requirements, or may be based on other transactions or
circumstances. The Company does not believe there are any such proceedings
presently pending that could have a material adverse effect on the
Company's financial condition except for the matters described in Note 14
to the accompanying Consolidated Financial Statements (which description
is incorporated herein by reference).

On September 9, 1998, Barbara Lawrence, the Lawrence Group, Inc.
("Lawrence"), and certain other Lawrence-related entities ("Plaintiffs")
filed suit in the United States Bankruptcy Court for the Northern District
of New York against First Albany Corporation ("FAC"), Dale Church, Edward
Dohring, Alan Goldberg, George McNamee, Beno Sternlicht, Marty Mastroianni
(former President and Chief Operating Officer of MTI) and 33 other
individuals ("Defendants") who purchased a total of 820,909 shares of MTI
stock from the Plaintiffs.  The complaint alleged that Defendants
purchased MTI stock from the Plaintiffs in violation of sections 10b, 20,
20A and rule 10b-5 of the Securities Exchange Act of 1934.  In December
1998, the complaint was amended to add MTI as a defendant and assert a
claim for common law fraud against all the Defendants including MTI.  The
case concerns the Defendants' 1998 purchase of MTI shares from the
Plaintiffs at the price of $2.25 per share.  Ownership of the shares was
disputed and several of the Plaintiffs were in bankruptcy at the time of
the sale.  FAC acted as Placement Agent for the Defendants in the
negotiation and sale of the shares and in proceedings before the
Bankruptcy Court for the Northern District of New York, which approved the
sale in September 1997.  Plaintiffs claim that the Defendants failed to
disclose material inside information concerning Plug Power, LLC to the
Plaintiffs and therefore the $2.25 per share purchase price was unfair.
Plaintiffs are seeking damages of $5 million plus punitive damages and
costs.  In April 1999, Defendants filed a motion to dismiss the amended
compliant, which was denied.  In June 1999, the parties agreed to stay
discovery and amend Defendants time to answer the amended complaint until
September 17, 1999.  In October 1999, Defendants answered the amended
Complaint.

ITEM 7:  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
         CONDITION AND RESULTS OF OPERATIONS


Results of Operations:  1999 in Comparison with 1998

The following three paragraphs summarize significant organizational
changes, which impact the comparison of 1999 and 1998 results of
operations.

On June 27, 1997, the Company and Edison Development Corp. ("EDC"), a
subsidiary of DTE Energy Co. formed a joint venture, Plug Power L.L.C.
("Plug Power") to further develop the Company's Proton Exchange Membrane
("PEM") Fuel Cell technology.  In exchange for its contribution of
employees, contracts, intellectual property and certain other assets that
had comprised the fuel cell research and development business activity of
the Technology segment (which assets had a net book value of $357
thousand), the Company received a 50% interest in Plug Power. EDC made an
initial cash contribution of $4.75 million in exchange for the remaining
50% interest in Plug Power.  The Company's investment in Plug Power is
included in the balance sheet caption "Investment in Plug Power"; the
assets contributed by the Company to Plug Power had previously been
included in the assets of the Company's Technology segment. See the
supplemental disclosure regarding Contribution of Net Assets to Plug Power
in the Consolidated Statements of Cash Flows for additional information
regarding the assets contributed by the Company to Plug Power.

Since Plug Power was formed in 1997 the Company, EDC and other investors
have contributed substantial amounts of cash and other assets to Plug
Power.  Contributions to Plug Power by the Company totaled $20.7 million
as of September 30, 1999 and increased to $41.2 million as of Plug
Power's IPO date.  After Plug Power' s IPO, the Company owned 13,704,315
shares or 31.9% of outstanding Plug Power stock.

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.  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 the net assets and operating results of the business.

The following is management's discussion and analysis of certain
significant factors, which have affected the Company's results of
operations for 1999 compared to 1998.  This discussion relates only to the
Company's continuing operations before the sale of Ling, which occurred in
<PAGE>
October 1999.

Sales for fiscal 1999 totaled $12.9 million compared to $21.0 million for
the prior year, a decrease of $8.1 million or 38.7%.  This decrease is the
result of continuing weak market conditions.  Advanced Products and Ling
reported sales decreases of 48.7% and 31.6%, respectively in the year
ended September 30, 1999.

Selling, general and administrative expenses for fiscal 1999 were 38.4% of
sales, as compared to 27.6% in 1998. Higher levels of
general/administrative expenses as a percentage of sales for fiscal 1999
resulted primarily from the 38.7% decrease in sales.  Actual selling,
general and administrative expenses decreased $.863 million from 1998 to
1999.

Product development and research costs during fiscal 1999 were 8.6% of
sales, compared to 4% for 1998.  Development costs increased $.274 million
from 1998 to 1999 reflecting the Advanced Products Division's commitment
to developing diagnostic and other new products.

The operating loss of $1.4 million for the year ended September 30, 1999
represents a $3.4 million or 170.4% decrease from the $2 million
operating income reported during the same period last year.  The
decrease is the result of decreased sales levels and corresponding
decreases in gross profits due to fixed cost absorption at lower sales
levels.  Gross profit decreased to 36% of sales in fiscal 1999 from 41%
of sales in fiscal 1998.

In addition to the matters noted above, the Company recorded a $9.4
million loss from the recognition of the Company's proportionate share of
losses of Plug Power compared to a $3.8 million loss in 1998.

Results during fiscal 1999 were adversely effected by the sales decrease.
Further, as a result of ownership changes in 1996, the availability of net
operating loss carryforwards to offset future taxable income will be
significantly limited pursuant to the Internal Revenue Code.


Results of Operations: 1998 in Comparison with 1997

The following two paragraphs summarize significant organizational changes,
which impact the comparison of 1998 and 1997 results of operations.

Net assets of the discontinued technology operation were $8 thousand and
$3,186 thousand at September 30, 1998 and 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 at September 30, 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.

On September 30, 1997, the Company sold all of the assets of its L.A.B.
Division to Noonan Machine Company of Franklin Park, IL.  The Company
received $2.6 million in cash and two notes, totaling $650 thousand, from
Noonan Machine Company. The purchaser has requested that the principal
amount of the note be reduced to reflect the resale value of certain
assets of L.A.B.  The Company is enforcing its rights with respect to the
<PAGE>
note.  The net proceeds from the sale were used to pay down outstanding
debt and build working capital.  The sale of L.A.B. resulted in a $2.0
million gain, which was recorded in the fourth quarter of fiscal year
1997.  In addition, $250 thousand of the proceeds associated with one of
the notes was recorded as deferred revenue due to the possible reduction
of the $250 thousand note receivable, in the event of a sale of certain
fixed assets, in accordance with the terms of the note.

The following is management's discussion and analysis of certain
significant factors, which have affected the Company's results of
operations for 1998 compared to 1997.  This discussion relates only to the
Company's continuing operations.

Sales for fiscal 1998 totaled $21.0 million compared to $24.1 million for
the prior year, a decrease of $3.1 million or 12.8%.  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
$3.3 million and operating income of $500 thousand at September 30, 1997.
Advanced Products reported a sales increase of 26.2% and Ling reported a
sales decrease of 11.3% in the year ended September 30, 1998.

Selling, general and administrative expenses for fiscal 1998 were 27.6% of
sales, as compared to 29.1% in 1997. Product development and research
costs during fiscal 1998 were 4% of sales, compared to 4.2% for 1997.
Lower levels of selling, general and administrative expenses for fiscal
1998 resulted primarily from cost reduction efforts during fiscal 1998 as
well as the elimination of costs for L.A.B. of $600 thousand.

Operating income of $2 million at September 30, 1998 represented a $400
thousand or 25.5% increase from the $1.6 million 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.  Excluding the L.A.B. division
results in 1997, operating income increased $900 thousand.

In addition to the matters noted above, during the fourth quarter of
fiscal 1998, the Company recorded a $3.8 million loss from the recognition
of the Company's proportionate share of losses in Plug Power compared to a
$330 thousand loss in 1997.  During the fourth quarter of fiscal 1997, the
Company recorded a $2.0 million gain on the sale of the L.A.B. Division.
Further, the Company recorded a $2.5 million extraordinary gain, net of
taxes, on the extinguishment of debt during the first quarter of fiscal
1997.

Results during fiscal 1998 were enhanced by lower interest expense,
principally resulting from reduced indebtedness. Moreover, the Company
benefited from reduced income tax expense due to the loss generated by
discontinued operations and the use of net operating loss carryforwards.
However, as a result of recent 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.

Liquidity and Capital Resources

At September 30, 1999, the Company's order backlog was $2.1 million,
representing no change from the prior year-end.

Inventories in 1999 remained stable at $3.75 million to support expected
sales increases during the first quarter of 2000.  Additionally, accounts
receivable decreased by $1.1 million in 1999 due to the reduced sales
during fiscal 1999.

Cash flow used by continuing operations was $2.3 million in 1999 compared
with $.5 million provided in 1998 and $1.1 million provided in 1997.  Cash
flow from operating activities was impacted in 1999 by operating losses
and 1998 and 1997 were impacted by positive operating income and
fluctuations in working capital components.

Working capital was $18.7 million at September 30, 1999, a $12.9 million
increase from $5.8 million at fiscal year-end 1998.  Capital increased
$12.7 million in 1999 which reflects the proceeds received from the sale
of common shares to existing shareholders through a rights offering.

Capital expenditures were $2.7 million for 1999, $3.2 million for 1998 and
$.4 million for 1997.  The capital expenditures in 1999 were in accordance
with the higher level of planned expenditures including the construction
of a new facility for Advanced Products and corporate headquarters and
renovations to an existing building, which were subsequently sold to Plug
Power in July 1999. Capital expenditures in 2000 are expected to
approximate $.4 million, which consists of expenditures for facility fit-
up and computer and manufacturing equipment.  The Company expects to
finance these expenditures with cash from operations and existing credit
facilities.

Cash and cash equivalents were $5.9 million at September 30, 1999 compared
to $5.6 million at September 30, 1998. Investments in marketable
securities were $7.9 million at September 30, 1999.  These increases are
primarily attributable to $12.7 million of net cash proceeds from the sale
of common shares to existing shareholders through a rights offering, which
closed on July 12, 1999 net of payments associated with the Company's
construction project.  During 1999, the Company also funded $4 million of
previously accrued capital contributions to Plug Power.

At September 30, 1999 and 1998, there were no borrowings outstanding on
the lines of credit.  The Company has a working capital line of credit
available in the amount of $4 million and a $1 million equipment line of
credit.  These lines of credit expire on January 31, 2000.  The Company is
currently negotiating an extension of these lines of credit.

The reduction in net assets of discontinued operations to a net liability
of $.5 million reflects the collection of receivables and settlement of
liabilities.  The sale of the Technology Division was completed as of
March 31, 1998.

KeyBank issued a letter of credit for approximately $6 million in
connection with the issuance of $6 million of Industrial Development
Revenue Bonds ("IDR Bonds").  The KeyBank credit agreements required the
Company to meet certain covenants, including a fixed charge coverage and
leverage ratio.  Further, if certain performance standards were achieved,
<PAGE>
the interest rates on the debt may be reduced.  The IDR Bond Obligation,
letter of credit and unexpended bond proceeds were transferred to Plug
Power in connection with the sale of the MTI facility and adjacent
residence effective July 1, 1999.

The Industrial Development Agency for the Town of Colonie issued $6
million in 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 leased to Plug Power.
The bond closing was completed December 17, 1998 and proceeds of the IDR
Bonds were deposited with a trustee for the bondholders.  The Company has
drawn bond proceeds to cover qualified project costs.

On November 1, 1999, the Company entered into a $22.5 million Credit
Agreement with KeyBank, N.A. ("the $22.5 million Credit Agreement").  The
proceeds of this loan were used to fund the Company's remaining $20.5
million balance of its Mandatory Capital Commitment to contribute $22.5
million to Plug Power. Pursuant to the Mandatory Capital Commitment, the
Company purchased 266,667 shares of Plug Power for $2 million on September
30, 1999 and 2,733,333 shares of Plug Power for $20.5 million in November
1999.  The Company may sell shares of Plug Power Common Stock to pay
monthly interest and or quarterly principal payments (beginning May 2001)
on the Loan.  Plug Power's stock is currently traded on the NASDAQ,
therefore the stock is subject to stock market conditions.  Due to the
Company's significant ownership position, sales of Plug Power stock will
be subject to SEC Rule 144 limitations including a limit of one (1)
percent of total outstanding shares per quarter.

The $22.5 million Credit Agreement requires the Company to meet certain
covenants, including maintenance of a collateral account which at all
times has a minimum market value of $600 thousand and a balance on
November 1, 1999 of $2.65 million, and maintenance of a collateral
coverage ratio.  The existing covenants under the original letter of
credit were eliminated pursuant to the $22.5 million Credit Agreement.
The $22.5 million Credit Agreement is collateralized by 100% of the
Company's equity interest in Plug Power.

On October 21, 1999, the Company created a strategic alliance with
SatCon Technology Corporation (SatCon).  SatCon acquired Ling
Electronics, Inc. and Ling Electronics, Ltd. from the Company and the
Company committed to invest approximately $7 million in SatCon.  In
consideration for the acquisition of Ling Electronics and the Company's
investment, the Company will receive 1,800,000 shares of SatCon's common
stock and warrants to purchase an additional 100,000 shares of SatCon's
common stock.  The Company funded $2.57 million of its investment in
SatCon and will make the remaining investment by the end of January
2000.  SatCon will also receive warrants to purchase 100,000 shares of
the Company's common stock.

The Company anticipates that it will be able to meet the liquidity needs
of its continuing operations and its investment commitment to SatCon
from current cash resources, cash flow generated by operations and
borrowing under its existing lines of credit.

Market Risk

Market risk represents the risk of changes in value of a financial
instrument, caused by fluctuations in interest rates and equity prices.

Because the Company's cash and investment position exceeds both short
and long term obligations, the Company's exposure to interest rate risk
relates primarily to its investment in marketable debt securities.  The
investments are at variable rates, which generally reflect market
conditions.  The Company manages its investments to increase return on
investment and only invests in instruments with high credit quality.

The Company has performed a sensitivity analysis on its marketable debt
securities and its investment in Plug Power common stock.  The
sensitivity analysis presents the hypothetical change in fair value of
those financial instruments held by the Company at September 30, 1999
which are sensitive to changes in interest rates.  Market risk is
estimated as the potential change in fair value resulting from an
immediate hypothetical one-percentage point parallel shift in the yield
curve.  The fair values of the Company's investments in marketable
securities have been based on quoted market prices.  As the carrying
amounts on short-term investments maturing in less than 180 days
approximate the fair value, these are not included in the sensitivity
analysis.  The fair value of marketable securities over 180 days is $3.0
million.  A one-percentage point change in the interest rates would
change the fair value of investments over 180 days by $85 thousand.

The Company also has an investment in Plug Power, which is accounted for
on the equity method.  The fair market value of the investment is $164.6
million based on the October 28, 1999 $15 per share initial public
offering price.  If the market price on the Plug Power stock would
decrease by ten percent the fair value of the stock would decrease by
$16.5 million.


Year 2000


The Company's Year 2000 plan is complete.  The plan addresses the issue
of computer programs and embedded computer chips being unable to
distinguish between the year 1900 and the year 2000 as well as the
ability to recognize the leap year date of February 29, 2000.  The plan
has been divided into six areas: (1)Systems evaluation, (2) Software
evaluation, (3) Third-party suppliers, (4) Facility systems, (5)
Products and (6)Contingency plans. The general phases common to all
segments are: (1) Inventorying Year 2000 items, (2) Assigning priorities
to identified items, (3) Assessing the Year 2000 compliance of items
determined to be material to the Company, (4) Repairing or replacing
material items that are determined not to be Year 2000 compliant, (5)
Testing material items and (6) Designing and implementing contingency
and business continuation plans for each organization and company
location.

Systems Evaluation

All internal systems have been identified, inventoried, prioritized and
assessed for Year 2000 compliance. Systems found to be non-compliant
<PAGE>
were replaced and compliant systems were assessed to determine what if
any maintenance is required to keep them compliant.  Plans have been
developed to ensure that staff is available to oversee restarting
certain machines and manually adjusting their dates.

Software Evaluation

All software material to the Company has been identified, evaluated, and
is now in compliance and certified as such by vendors or new software
has been purchased.


Third-Party Suppliers

Third-party suppliers have been identified and reviewed to determine
whether their products and supplies are Year 2000 compliant.  Any
provider identified as non-compliant has been or will be replaced with
an alternative provider if they cannot serve our needs.

Facility Systems

All facility systems are believed to be Year 2000 compliant including
telephone, fire alarm, security and network components.

Products

The Company has evaluated both current product offerings and products in
the field to determine their ability to comply with Year 2000 issues.
The products were found to fall into three categories, non-compliant,
compliant if modifications are made and fully compliant or not impacted
(that is, the product does not have a computer or contains an embedded
computer but does not use a date function).  All products currently sold
by the Company are fully Year 2000 compliant.  The Company has produced
and made available for sale, upgrades to products requiring
modifications to be Year 2000 compliant.  Those products identified as
non-compliant are products that have been in the field for a number of
years and must be replaced by the customer.

Contingency Plans

In the event the Company's Year 2000 plan is ineffective or
unanticipated problems arise, the Company has developed contingency
plans which are now in place.  The plans include use of hard copy data
and alternate suppliers.

Costs

The total cost associated with required modifications to become Year
2000 compliant is not expected to be material to the Company's financial
position.  The estimated total cost of the Year 2000 project was
approximately $120 thousand, which included software, hardware and
cabling upgrade and replacement costs.  This estimate does not include
the Company's potential share of Year 2000 costs that may be incurred by
joint ventures, in which the company participates but is not the
operator.  The total amount expended on the Plan through September 30,
1999 was $124 thousand for the upgrade and replacement of hardware.

Risks

The failure to correct a material Year 2000 problem could result in an
interruption in, or a failure of, certain normal business activities or
operations.  Such failures could materially and adversely affect the
Company's results of operations, liquidity and financial condition.  Due
to the general uncertainty inherent in the Year 2000 problem, resulting
in part from the uncertainty of the Year 2000 readiness of third-party
suppliers and customers, the Company is unable to determine at this time
whether the consequences of Year 2000 failures will have a material
impact on the Company's results of operations, liquidity or financial
condition. The Year 2000 Plan is expected to significantly reduce the
Company's level of uncertainty about the Year 2000 problem and, in
particular, about the Year 2000 compliance and readiness of its material
customers.  The Company believes that, with its Year 2000 Plan, the
possibility of significant interruptions of normal operations should be
reduced.

reporting under item 5 thereof that on November 8, 1999 Plug Power

obligations owed to DCT, Inc. were breached.

(d) Separate financial statements for Plug Power, Inc., a less than fifty

Separate financial statements of the registrant alone are omitted because
the registrant is primarily an operating company and all subsidiaries
included in the consolidated financial statements being filed, in the
aggregate, do not have minority equity interest and/or indebtedness to
any person other than the registrant or its consolidated subsidiaries in
amounts which together exceed 5% of the total assets as shown by the most
recent year-end consolidated balance sheet.

                         REPORT OF INDEPENDENT ACCOUNTANTS



To the Board of Directors and Shareholders
of Mechanical Technology Incorporated

In our opinion, the accompanying consolidated balance sheets and the
related consolidated statements of operations and retained earnings and
of cash flows present fairly, in all material respects, the financial
position of Mechanical Technology Incorporated and Subsidiaries at
September 30, 1999 and 1998, and the results of their operations and
their cash flows for each of the three years in the period ended
September 30, 1999, in conformity with generally accepted accounting
principles.  These financial statements are the responsibility of the
Company's management; our responsibility is to express an opinion on
these financial statements based on our audits.  We conducted our audits
of these statements in accordance with generally accepted auditing
standards which require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of
material misstatement.  An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial
statements, assessing the accounting principles used and significant
estimates made by management, and evaluating the overall financial
statement presentation.  We believe that our audits provide a reasonable
basis for the opinion expressed above.

                      NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(1) Accounting Policies

Principles of Consolidation

The consolidated financial statements include the accounts of the Company
and its subsidiaries. All significant intercompany transactions and
accounts have been eliminated.  The Company has a 40.65% interest in Plug
Power, L.L.C. ("Plug Power").  The consolidated financial statements
include the Company's investments in Plug Power (including obligations to
invest), plus its share of losses.  The investment is included in the
financial line "Investment in Plug Power".

Use of Estimates

The preparation of the consolidated financial statements in conformity
with generally accepted accounting principles requires management to make
estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the
date of the consolidated financial statements and the reported amounts of
revenues and expenses during the reporting period. Actual results could
differ from those estimates.

Financial Instruments

The fair value of the Company's financial instruments including cash and
cash equivalents, investments, line-of-credit, note payable and long-term
debt, approximates carrying value. Fair values were estimated based on
quoted market prices, where available, or on current rates offered to the
Company for debt with similar terms and maturities.

Inventories

Inventories are stated at the lower of cost (first-in, first-out) or
market.

Property, Plant, and Equipment

Property, plant and equipment are stated at cost and depreciated using
primarily the straight-line method over their estimated useful lives:

Buildings and improvements		20 to 40 years
Leasehold improvements			   10    years
Machinery and equipment			 2 to 10 years
Office furniture and fixtures		 3 to 10 years

Significant additions or improvements extending assets' useful lives are
capitalized; normal maintenance and repair costs are expensed as
incurred.  The costs of fully depreciated assets remaining in use are
included in the respective asset and accumulated depreciation accounts.

                      NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(1)  Accounting Policies (continued)

When items are sold or retired, related gains or losses are included in
net income.

Income Taxes

The Company accounts for taxes in accordance with Financial Accounting
Standard No. 109, "Accounting for Income Taxes," which requires the use
of the asset and liability method of accounting for income taxes.  Under
the asset and liability method, deferred income taxes are recognized for
the tax consequences of "temporary differences" by applying enacted
statutory tax rates applicable for future years to differences between
financial statement and tax bases of existing assets and liabilities.
Under FAS No. 109, the effect of tax rate changes on deferred taxes is
recognized in the income tax provision in the period that includes the
enactment date.  The provision for taxes is reduced by investment and
other tax credits in the years such credits become available.

Revenue Recognition

Sales of products are recognized when products are shipped to customers.
Sales of products under long-term contracts are recognized under the
percentage-of-completion method. Percentage-of-completion is based on the
ratio of incurred costs to current estimated total costs at completion.
Total contract losses are charged to operations during the period such
losses are estimable.

Foreign Currency Translation

Assets and liabilities of the foreign subsidiary are translated at year-
end rates of exchange, and revenues and expenses are translated at the
average rates of exchange for the year. Gains or losses resulting from
the translation of the foreign subsidiary's balance sheet are accumulated
in a separate component of shareholders' equity.

Cash and Cash Equivalents

Cash and cash equivalents consist of cash and highly liquid short-term
investments with maturities of less than three months.

Investments in Marketable Securities
Management determines the appropriate classification of its investments
in marketable securities at the time of purchase and reevaluates such
determinations at each balance sheet date.  Marketable securities for
which the Company does not have the intent or ability to hold to
maturity are classified as available for sale along with any

                      NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

investments in mutual funds.  Securities available for sale are carried
at fair value, with the unrealized gains and losses, net of income
taxes, reported as a separate component of Shareholders' Equity.  The
Company has had no investments that qualify as trading or held to
maturity.

The amortized cost of debt securities is adjusted for accretion of
discounts to maturity.  Such accretion as well as interest are included
in interest income.  Realized gains and losses are included in Other
income (expense), net in the Consolidated Statements of Operations. The
cost of securities sold is based on the specific identification method.

The Company's investments in marketable securities are diversified among
high-credit quality securities in accordance with the Company's
investment policy.

Earnings (Loss) Per Share

Effective October 1, 1997, the Company adopted Financial Accounting
Standard No. 128, "Earnings per Share."  In accordance with this
Standard, net income(loss) per share is computed using the weighted
average number of common shares outstanding during each year.  Diluted
net income(loss) per share includes the effects of all potentially
dilutive securities.  Earnings per share amounts for all periods
presented have been computed in accordance with this Standard.

Advertising

The costs of advertising are expensed as incurred.  Advertising expense
was approximately $102, $83 and $92 thousand in 1999, 1998, and 1997,
respectively.

Asset Impairment

The Company adopted SFAS No. 121, "Accounting For The Impairment of Long-
Lived Assets and for Long-Lived Assets To Be Disposed Of."  This
statement requires companies to record impairments to long-lived assets,
certain identifiable intangibles, and related goodwill when events or
changing circumstances indicate a probability that the carrying amount of
an asset may not be fully recovered.  Impairment losses are recognized
when expected future cash flows are less than the asset's carrying value.

Reclassification and Restatement

Certain 1998 and 1997 amounts have been reclassified to conform to the
1999 presentation.  The financial statements for 1997 have also been
restated to reflect the discontinuance of the Company's Technology
Division (See Note 16).

The difference between the amortized cost of available for sale
securities and their fair market value results in unrealized gains and
losses, which are recorded as a separate component of stockholders'
equity.  Gross realized gains and losses on sales of available for sale
securities were immaterial in 1999, 1998 and 1997.

The estimated fair value of available for sale securities by contractual
maturity is as follows:


 (Dollars in thousands)                           1999

Due in one year or less                        $ 4,916
Due after one year through three years               -

Expected maturities may differ from contractual maturities because the
issuers of the securities may have the right to prepay obligations
without prepayment penalties.

(6) Investment in Plug Power, L.L.C.

On June 27, 1997, the Company and Edison Development Corp. ("EDC"), a
subsidiary of DTE Energy Co. formed a joint venture, Plug Power, L.L.C.
("Plug Power"), to further develop the Company's Proton Exchange Membrane
("PEM") Fuel Cell technology. In exchange for its contribution of
contracts and intellectual property and certain other net assets that had
comprised the fuel cell research and development business activity of the
Technology segment (which assets had a net book value of $357 thousand),
the Company received a 50% interest in Plug Power.  EDC made an initial
cash contribution of $4.75 million in exchange for the remaining 50%
interest in Plug Power. The Company's investment in Plug Power is
included in the balance sheet caption "Investment in Plug Power"; the
assets contributed by the Company to Plug Power in fiscal 1997 had
previously been included in the assets of the Company's Technology
segment. See the supplemental disclosure regarding Contribution of Net
Assets to Plug Power in the Consolidated Statements of Cash Flows for
additional information regarding the assets contributed by the Company to
Plug Power.  The Company recorded the carrying value of the net assets
contributed as its initial investment in Plug Power in recognition of the
nature of the venture's undertaking.

(6) Investment in Plug Power, L.L.C.  (continued)

On April 15, 1998, EDC contributed $2.25 million in cash to 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 thousand of EDC's contribution.
In May 1998, EDC contributed an additional $2 million to Plug Power and
the Company purchased another one-year option to match the contribution.
The Company paid approximately $191 thousand for the options, which were
scheduled to mature April 24, 1999 ($250 thousand) and June 15, 1999 ($2
million).

As of March 25, 1999, the Company and Plug Power exchanged the foregoing
options and certain "research credits" (described below) for 2.25
million Plug Power membership interests.  The Company earned the
research credits by assisting Plug Power in securing the award of
certain government grants and research contracts during the period June
1997 through April 1999.

In August, 1998, the Company committed to contribute an additional $5
million dollars (in cash, accounts receivable and research credits) to
Plug Power between August 5, 1998 and March 31, 1999 and recorded a
liability representing this obligation. During the period from September
1998 to February 1999, the Company fully funded this commitment by
contributing $4 million cash and converting $.5 million of accounts
receivable and $.5 million of notes receivable.

During April 1999, the Company and EDC amended and restated the Plug
Power Mandatory Capital Contribution Agreement. The agreement, which was
effective as of January 26, 1999, stated that, in the event Plug Power
determined that it required funds at any time through December 31, 2000,
Plug Power had the right to call upon the Company and EDC to each make
capital contributions as follows:

  *  The Company and EDC would each fund capital calls of up to $7.5
     million in 1999 and $15 million in 2000 ("Capital Commitment").
  *  In exchange for such capital contributions to Plug Power, the
     Company and EDC would receive class A membership interests
     ("Shares") from Plug Power at $7.50 per share.
  *  The Company and EDC would share the Capital Commitment equally.
  *  Plug Power's Board of Managers would determine when there is
     need for such capital contributions.
  *  The Company and EDC would have sixty (60) days from the date of
     such authorization to tender their payment to Plug Power.

The agreement was scheduled to terminate on December 31, 2000 or the
date of an initial public offering of shares by Plug Power at a per

share price of greater than $7.50 per share ("Termination Date").
In exchange for the Capital Commitment, Plug Power agreed to permit the
Company and EDC to make capital contributions to the extent of their
Capital Commitment on the Termination Date, whether or not such funds
have been called, in exchange for shares at the fixed price of $7.50 per
share.

In June 1999, the Company and Plug Power entered into an agreement for
the sale of the MTI campus and adjacent residence, including all land
and buildings, to Plug Power in exchange for 704,315 Class A membership
interests and the assumption of approximately $6 million in debt by Plug
Power.  The sale of the MTI facility and the transfer of the $6 million
IDR bonds to Plug Power were effective as of July 1, 1999 with no gain
or loss recognized.

In August 1999, the Company committed to purchase 3 million shares of
Plug Power if the public offering price of Plug Power's stock was
greater than $7.50 per share. The Mandatory Capital Contribution
Agreement between the Company and Plug Power, dated as of January 26,
1999 was amended and restated to reflect this commitment.

On September 30, 1999, the Company purchased 266,667 shares of Plug
Power at $7.50 per share.  This purchase reduced the Company's
commitment to purchase Plug Power shares at the time of its public
offering from 3,000,000 shares to 2,733,333 shares at a price of $7.50
per share.

The Company's total contributions to Plug Power (including contributions
of cash, assets, research credits, below market lease and real estate)
for the period commencing on June 27, 1997, and ending September 30,
1999 total $20.7 million.

During calendar 1999, Plug Power's equity increased approximately
$50.628 million primarily due to investments by investors.  Of this
amount, $30.368 million was received in cash, $9.010 million in property
and services and $11.250 million represents membership interests issued
in connection with the formation of GE Fuel Cell Systems LLC.  As a
result, the Company recorded its proportionate share of the increase in
Plug Power's equity ($14.854 million) as investment in Plug Power and
additional paid-in capital.

The Company has recorded its proportionate share of Plug Power's losses
to the extent of its recorded investment in Plug Power.  The carrying
value of the Company's investment is $8.71 million as of September 30,
1999 for a 40.65% interest in Plug Power.

future to the extent of its carrying value and additional future
investments.

On November 1, 1999, the Company purchased 2,733,333 shares of Plug
Power at $7.50 per share.  This purchase completed the Company's
commitment to purchase Plug Power shares at the time of its public
offering.  Plug Power's public offering was completed at $15 per share.
The Company's total contributions to Plug Power as of November 1, 1999
total $41.2 million.  Immediately after the Plug Power IPO, the Company

(9) Debt

The Company has a working capital line of credit available in the amount
of $4 million with interest payable monthly at a rate of prime (8.25% and
8.5% at September 30, 1999 and 1998, respectively) or LIBOR plus 2.5%
(7.9% and 7.875% at September 30, 1999 and 1998, respectively).  This
obligation is collateralized by the assets of the Company, exclusive of
its investment in Plug Power.  The Company also has a $1 million
equipment loan/lease line of credit at an interest rate of LIBOR plus
2.75% (8.15% and 8.125% at September 30, 1999 and 1998, respectively).
This obligation is collateralized by the equipment purchased under the
line of credit.   The lines of credit expire on January 31, 2000.  No
amounts were outstanding under these lines at September 30, 1999 and
1998.

On December 17, 1998, the Industrial Development Agency for the Town of
Colonie issued $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 leased to Plug Power.  The IDR Bond proceeds were
deposited with a trustee for the bondholders and the Company drew bond
proceeds to cover qualified project costs. First Albany Companies Inc.
("FAC"), which owns 34% of the Company's stock, underwrote the sale of
the IDR Bonds. FAC received no fees for underwriting the IDR Bonds but
will be reimbursed for its out-of-pocket costs.

KeyBank issued a letter of credit (the credit agreement) for
approximately $6 million in connection with the $6 million IDR Bonds. The
KeyBank credit agreements require 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 credit agreement also requires the Company to grant a first lien on
all consolidated assets of the Company, exclusive of its investment in
Plug Power, a first mortgage on all land and buildings owned by the
Company and a first lien on any equipment purchased by the Company.

The IDR Bond Obligation, letter of credit and unexpended bond proceeds
were transferred to Plug Power in connection with the sale of the MTI
facility and adjacent residence effective July 1, 1999.

Company has pledged 13,704,315 shares of Plug Power Common Stock as
collateral for its $22.5 million loan from KeyBank, N.A. ("Loan").  The
proceeds of this loan were used to fund the Company's remaining $20.5
million balance of its Mandatory Capital Commitment to contribute $22.5
million to Plug Power.  Although the Credit Agreement does not require
the Company to sell shares of Plug Power Common Stock, the Company may
sell shares of Plug Power Common Stock to pay interest or principal on
the Loan.  Pursuant to the $22.5 million Credit Agreement, the Company is
obligated to make interest only payments for the first 18 months
following the closing of the Loan, and to repay the principal in 6 equal
quarterly installments of $3.750 million each, commencing on June 30,
2001.  In addition, a one time commitment fee totaling $247,500 is
payable for the Loan, $75,000 of which was paid as of September 30, 1999.
 Interest is payable monthly at a rate of Prime (8.25% on November 1,
1999) or if certain performance standards are achieved, the interest
rates on the $22.5 million Credit Agreement may be reduced.

The $22.5 million Credit Agreement requires the Company to meet certain
covenants, including maintenance of a collateral account which at all
times has a minimum market value of $600 thousand and a balance on
November 1, 1999 of $2.65 million, and maintenance of a collateral
coverage ratio.  The existing covenants under the original letter of
credit were eliminated pursuant to the $22.5 million Credit Agreement.

The weighted average interest rate for the Note Payable, IDR Bonds and
Line of Credit during 1999 was 5.11%, 9.02% during 1998 and 10.75% during
1997.

Cash payments for interest were $164, $97 and $201 thousand for 1999,
1998 and 1997, respectively.

During fiscal 1999, options to purchase 741,613 shares of common stock
at prices ranging between $1.63 and $22.50 per share were outstanding but
were not included in the computation of Earnings per Share-assuming
dilution because the Company incurred a loss from continuing operations
and inclusion would be anti-dilutive.  The options expire between
December 20, 2006 and June 16, 2009.

During fiscal 1998, options to purchase 607,372 shares of common stock at
prices ranging from $1.63 to $4 per share were outstanding but were not
included in the computation of Earnings per Share-assuming dilution
because the Company incurred a loss from continuing operations and
inclusion would be anti-dilutive.  The options expire between December
20, 2006 and August 31, 2008.

(12) Stock Option Plan

During March 1999, the shareholders approved the 1999 Employee Stock
Incentive Plan ("1999 Plan").  The 1999 Plan provides that an initial
aggregate number of 1 million shares of common stock may be awarded or
issued.  The number of shares available under the 1999 Plan may be
adjusted for stock splits and during 1999 the number of shares available
under the plan increased to 1,500,000 shares.  Under the 1999 Plan, the
Board of Directors is authorized to award stock options to officers,
employees and others.

(12) Stock Option Plan (continued)

During December 1996, the shareholders approved a stock incentive plan
("1996 Plan"). The 1996 Plan provides that an initial aggregate number of
500,000 shares of common stock may be awarded or issued.  The number of
shares available under the 1996 Plan may be increased by 10% of any
increase in the number of outstanding shares of common stock for reasons
other than shares issued under this 1996 Plan.  During 1999 and 1998, the
number of shares available under the 1996 Plan increased to 1,159,582 and
719,640 shares respectively.  Under the 1996 Plan, the Board of Directors
is authorized to award stock options, stock appreciation rights,
restricted stock, and other stock-based incentives to officers, employees
and others.

Options are generally exercisable in from one to five cumulative annual
amounts beginning 12 months after the date of grant.  Certain options
granted may be exercisable immediately.  Option exercise prices are not
less than the market value of the shares on the date of grant.
Unexercised options generally terminate ten years after grant.

During 1999, the Company awarded 15,000 options to a consultant.  The
fair value of these options ($55 thousand) was charged to expense.

For the purpose of applying Financial Accounting Standard No. 123 ("FAS
123"), "Accounting for Stock-Based Compensation", the fair value of each
option granted is estimated on the grant date using the Black-Scholes
Single Option model.  The dividend yield was 0% for 1999, 1998, and 1997,
respectively.  The expected volatility was 78% in 1999, 102% in 1998 and
78% in 1997. The expected life of the options is 5 years. The risk free
interest rate ranges from 4.37% to 5.81% in 1999, 5.52% to 5.85% in 1998
and 6.12% to 6.67% in 1997. The Company applies Accounting Principles
Board Opinion No. 25, "Accounting for Stock Issued to Employees," in
accounting for stock options. Accordingly, no compensation cost has been
recognized in 1999, 1998 or 1997.  Had compensation cost and fair value
been determined pursuant to FAS 123, net loss would increase from
$(10,688) to $(11,988) thousand in 1999 and from $(4,316) to $(4,773)
thousand in 1998 and net income would decrease from $4,520 to $4,351
thousand in 1997.  Basic and diluted loss per share would increase from
$(0.94) to $(1.06) in 1999 and from $(0.45) to $(0.50) in 1998 and basic
and diluted earnings per share would decrease from $0.49 to $0.48 in
1997.  The weighted average fair value of options granted during 1999,
1998 and 1997 for purposes of FAS 123, is $5.80, $4.70 and $1.96 per
share, respectively.

(13) Retirement Plan

The Company maintains a voluntary savings and retirement plan (Internal
Revenue Code Section 401(k) Plan) covering substantially all employees.
The Company plan allows eligible employees to contribute a percentage of
their compensation; the Company makes additional contributions in amounts
as determined by management and the Board of Directors.  The investment
of employee contributions to the plan is self-directed.  The cost of the
plan was $168, $152 and $179 thousand for 1999, 1998 and 1997,
respectively.

(14)	Commitments and Contingencies

On September 9, 1998, Barbara Lawrence, the Lawrence Group, Inc.
("Lawrence"), and certain other Lawrence-related entities ("Plaintiffs")
filed suit in the United States Bankruptcy Court for the Northern
District of New York against First Albany Corporation, a wholly owned
subsidiary of First Albany Companies Inc., Dale Church, Edward Dohring,
Alan Goldberg, George McNamee, Beno Sternlicht, Marty Mastroianni (former
President and Chief Operating Officer of the Company) and 33 other
individuals ("Defendants") who purchased a total of 820,909 shares of MTI
stock from the Plaintiffs. The complaint alleged that Defendants
purchased MTI stock from the Plaintiffs in violation of sections 10b, 20,
20A and rule 10b-5 of the Securities Exchange Act of 1934.  In December
1998, the complaint was amended to add MTI as a defendant and assert a
Claim for common law fraud against all the Defendants including the
Company.  The case concerns the Defendants' 1998 purchase of MTI shares
from the Plaintiffs at the price of $2.25 per share.  Ownership of the
shares was disputed and several of the Plaintiffs were in bankruptcy at
the time of the sale.  First Albany Corporation acted as Placement Agent
for the Defendants in the negotiation and sale of the shares and in
proceedings before the Bankruptcy Court for the Northern District of New
York, which approved the sale in September 1997.  Plaintiffs claim that
the Defendants failed to disclose material inside information concerning
Plug Power, LLC to the Plaintiffs and therefore the $2.25 per share
purchase price was unfair.  Plaintiffs are seeking damages of $5 million
plus punitive damages and costs.  In April 1999, Defendants filed a
motion to dismiss the amended complaint, which was denied.  In June 1999,
the parties agreed to stay discovery and amend Defendants time to answer
the amended complaint until September 17, 1999.  In October 1999,
Defendants answered the amended Complaint.

During October 1998, a legal action brought by a group of investors
against the Company related to a stock purchase agreement and side letter
agreements for the sale of the stock of the Company's wholly owned
subsidiary, Ling Electronics, Inc. ("Ling"), was determined in favor of
the Company.

(14)    Commitments and Contingencies (continued)

In February 1995, Ling made a voluntary disclosure to the United States
Department of Commerce regarding unlicensed exports of certain products
shipped in the first four months of fiscal 1995. Ling has fully
cooperated with the Office of Export Enforcement, which has not taken any
action to date. Possible administrative sanctions include: no action; a
warning letter; denial of export privileges; and/or imposition of civil
penalties. Foreign sales represent a significant portion of Ling's total
revenue. The final outcome of this matter is not presently determinable
and, therefore no provision for any liability that may result has been
recorded in the Company's financial statements.

The Company and its subsidiaries lease certain manufacturing, warehouse
and office facilities.  The leases generally provide for the Company to
pay increases over a base year level for taxes, maintenance, insurance
and other costs of the leased properties.  The leases contain renewal
provisions.

Future minimum rental payments required under noncancelable operating
leases are (dollars in thousands): $269 in 2000; $305 in 2001; $304 in
2002; $300 in 2003; and $300 in 2004.  Rent expense under all leases was
$482, $403 and $446 thousand for 1999, 1998 and 1997, respectively.

Rental income under all sub-leases was $164, $66 and $19 thousand in
1999, 1998 and 1997, respectively.

(15) Related Party Transactions

At September 30, 1999 First Albany Companies Inc. ("FAC") owned
approximately 34% of the Company's Common Stock (See Note 19).

During fiscal 1999, 1998 and 1997, First Albany Corporation, a wholly
owned subsidiary of FAC, provided financial advisory services in
connection with the sale of the Technology Division in 1999 and 1998 and
the L.A.B. Division in 1997, for which First Albany Corporation was paid
fees of $15, $10 and $75 thousand, respectively.

Amounts receivable from an officer totaled approximately $38 thousand and
is included in the balance sheet caption "Other receivables-related
parties" at September 30, 1999.

On June 27, 1997, the Company entered into a management services
agreement with Plug Power to provide certain services and facilities for
a period of one year. This agreement expired on June 27, 1998.  The
Company continued to provide services, which were billed on a cost
reimbursement basis.  During 1998, the Company entered into leases for
manufacturing, laboratory and office space which expired on July 1, 1999
pursuant to the sale of the MTI facility to Plug Power in exchange for
704,315 Plug Power Class A membership interests and the assumption of $6
million in debt by Plug Power.

(15) Related Party Transactions (continued)

Billings under these agreements amounted to $448, $661 and $65 thousand
for 1999, 1998 and 1997, respectively. Amounts receivable from Plug Power
under these agreements is included in the balance sheet caption "Other
receivables-related parties".

On September 30, 1999, the Company made an additional cash contribution
of approximately $2 million to Plug Power in exchange for 266,667 Plug
Power Class A membership interests.

On July 1, 1999, the Company contributed the MTI campus to Plug Power in
exchange for 704,315 Plug Power Class A membership interests.  During the
remainder of 1999, the Company paid $59 thousand to Plug Power in
connection with a lease of office and manufacturing space.  This lease
will terminate on November 24, 1999.

On August 5, 1998, the Company made a short-term loan to Plug Power of
$500 thousand, which was subsequently contributed to capital on September
23, 1998.  The Company also converted $500 thousand of its accounts
receivable from Plug Power to capital on September 23, 1998.  At
September 30, 1998, the remaining obligation to provide additional funds
to Plug Power was $4 million. During fiscal 1999, the Company fully
funded this commitment by contributing $4 million cash.


(16) Discontinued Operations

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, 1998, and the consolidated
financial statements have been restated to report separately the net
assets and operating results of the business.  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 thousand of
liabilities; and (c) established a credit for warranty work of
approximately $35 thousand.

(17) Sale of Division/Subsidiary

L.A.B. Division

On September 30, 1997, the Company sold all of the assets of its L.A.B.
Division to Noonan Machine Company of Franklin Park, IL.  The Company
received $2.60 million in cash and two notes, totaling $650 thousand,
from Noonan Machine Company. The purchaser has requested that the
principal amount of the note be reduced to reflect the resale value of
certain assets of L.A.B.  The Company is enforcing its rights with
respect to the note.  The net proceeds from the sale were used to pay
down all outstanding debt and build working capital.

The sale resulted in a $2.0 million gain, which was recorded in the
fourth quarter of fiscal year 1997.  In addition, $250 thousand of the
proceeds associated with one of the notes was recorded as deferred
revenue due to contingencies associated with the realization of this
note.  This note is still outstanding as of September 30, 1999.

In 1999, no customers accounted for more than 10% of sales and in 1998,
one customer accounted for 11.5% of sales.

The Company operates in two business segments, Alternative Energy
Technology and Test and Measurement. The Alternative Energy Technology
segment incubates alternative energy technology. The Test and Measurement
segment develops, manufactures, markets and services sensing instruments,
computer-based balancing systems for aircraft engines, vibration test
systems and power conversion products.

The accounting policies of the Alternative Energy Technology and Test and
Measurement segments are the same as those described in the summary of
significant accounting policies. The Company evaluates performance based
on profit or loss from operations before income taxes, accounting
changes, non-recurring items and interest income and expense.  Inter-
segment sales are not significant.

Summarized financial information concerning the Company's reportable
segments is shown in the following table.  The "Other" column includes
corporate related items and items like income taxes or unusual items,
which are not allocated to reportable segments.  In addition, segments
noncash items include any depreciation and amortization in reported
profit or loss.  For the Alternative Energy Technology segment, the
information is based on an annual period from October 1 to September 30
derived from Plug Power's unaudited financial statements.

(19) Extraordinary Item - Extinguishment of Debt

During fiscal 1996, 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 also acquired certain rights to an
obligation ("Term Loan") due from the same finance company ("FCCC") to
whom the Company was obligated under a Note Payable, due December 31,
1996.

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. The Company and FAC entered into an agreement dated as of
December 27, 1996 under which the Company issued to FAC 1.0 million
shares  of  Common  Stock  in  full  satisfaction  of  the Note Payable
and accrued interest.

(19) Extraordinary Item - Extinguishment of Debt (continued)

If FCCC were to seek collection of the Note Payable plus accrued
interest from the Company, the Company, based on the opinion of counsel,
believes that the outcome of any such action pursued by FCCC against the
Company would not have a material adverse impact on the Company's
financial position or results of operation.

the Company will receive 1,800,000 shares of SatCon's common stock and
warrants to purchase an additional 100,000 shares of SatCon's common
stock.  The Company immediately funded $2.57 million of its investment
in SatCon and will make the remaining investment by the end of January
2000. SatCon will also receive warrants to purchase 100,000 shares of
the Company's common stock.

for all reasonably anticipated material losses and costs and expenses. The

such action, suit or proceeding; (b) neither the Company nor any of the
Subsidiaries, nor any officer, director or employee of any of the foregoing,

nature which are adequate and customary for the Company's and the Subsidiaries'
business. All premiums due on the Insurance Policies or renewals thereof have
been paid, if billed, and there is no default under the Insurance Policies.
Except as set forth on Schedule 3.8, neither the Company nor any of the

8.3 Indemnification Claims.

(a)	A party entitled, or seeking to assert rights, to indemnification under
this Section 8 (an "Indemnified Party") shall give written notification to the
party from whom indemnification is sought (an "Indemnifying Party") of the
commencement of any suit or proceeding relating to a third party claim for
which indemnification pursuant to this Section 8 may be sought. Such
notification shall be given within 20 days after receipt by the Indemnified
Party of notice of such suit or proceeding, and shall describe in reasonable
detail (to the extent known by the Indemnified Party) the facts constituting
the basis for such suit or proceeding and the amount of the claimed damages;
provided, however, that no delay on the part of the Indemnified Party in
notifying the Indemnifying Party shall relieve the Indemnifying Party of any
liability or obligation hereunder except to the extent of any damage or
liability caused by or arising out of such failure. Within 20 days after
delivery of such notification, the Indemnifying Party may, upon written notice
thereof to the Indemnified Party, assume control of the defense of such suit or
proceeding with counsel reasonably satisfactory to the Indemnified Party;
provided that (i) the Indemnifying Party may only assume control of such
defense if it acknowledges in writing to the Indemnified Party that any
damages, fines, costs or other liabilities that may be assessed against the
Indemnified Party in connection with such suit or proceeding constitute Losses
for which the Indemnified Party shall be indemnified pursuant to this Section 8
and (ii) the Indemnifying Party may not assume control of the defense of a suit
or proceeding involving criminal liability or in which equitable relief is
sought against the Indemnified Party. If the Indemnifying Party does not so
<PAGE>
assume control of such defense, the Indemnified Party shall control such
defense. The party not controlling such defense (the "Non-controlling Party")
may participate therein at its own expense; provided that if the Indemnifying
Party assumes control of such defense and the Indemnified Party reasonably
concludes that the Indemnifying Party and the Indemnified Party have
conflicting interests or different defenses available with respect to such suit
or proceeding, the reasonable fees and expenses of counsel to the Indemnified
Party shall be considered "Losses" for purposes of this Agreement. The party
controlling such defense (the "Controlling Party") shall keep the
Non-controlling Party advised of the status of such suit or proceeding and the
defense thereof and shall consider in good faith recommendations made by the
Non-controlling Party with respect thereto. The Non-controlling Party shall
furnish the Controlling Party with such information as it may have with respect
to such suit or proceeding (including copies of any summons, complaint or other
pleading which may have been served on such party and any written claim,
demand, invoice, billing or other document evidencing or asserting the same)
and shall otherwise cooperate with and assist the Controlling Party in the
defense of such suit or proceeding. The Indemnifying Party shall not agree to
any settlement of, or the entry of any judgment arising from, any such suit or
proceeding without the prior written consent of the Indemnified Party, which
shall not be unreasonably withheld or delayed. The Indemnified Party shall not
agree to any settlement of, or the entry of any judgment arising from, any such
suit or proceeding without the prior written consent of the Indemnifying Party,
which shall not be unreasonably withheld or delayed.

(b)	In order to seek indemnification under this Section 8, an Indemnified
Party shall give written notification (a "Claim Notice") to the Indemnifying
Party which contains (i) a description and the amount (the "Claimed Amount") of
any Losses incurred or reasonably expected to be incurred by the Indemnified
Party, (ii) a statement that the Indemnified Party is entitled to
indemnification under this Section 8 for such Losses and a reasonable
explanation of the basis therefor, and (iii) a demand for payment (in the
manner provided in paragraph (c) below) in the amount of such Losses.

(c)	Within 20 days after delivery of a Claim Notice, the Indemnifying Party
shall deliver to the Indemnified Party a written response (the "Response") in
which the Indemnifying Party shall: (i) agree that the Indemnified Party is
entitled to receive all of the Claimed Amount (in which case the Response shall
be accompanied by a payment by the Indemnifying Party to the Indemnified Party
of the Claimed Amount, by check or by wire transfer, (ii) agree that the
Indemnified Party is entitled to receive part, but not all, of the Claimed
Amount (the "Agreed Amount") (in which case the Response shall be accompanied
by a payment by the Indemnifying Party to the Indemnified Party of the Agreed
Amount, by check or by wire transfer, or (iii) dispute that the Indemnified
Party is entitled to receive any of the Claimed Amount. If the Indemnifying
Party in the Response disputes its liability for all or part of the Claimed
Amount, the Indemnifying Party and the Indemnified Party shall follow the
procedures set forth in Section 8.03(d) for the resolution of such dispute (a
"Dispute").

(d)	During the 60-day period following the delivery of a Response that
reflects a Dispute, the Indemnifying Party and the Indemnified Party shall use
good faith efforts to resolve the Dispute. If the Dispute is not resolved
within such 60-day period, the Indemnifying Party and the Indemnified Party
shall discuss in good faith the submission of the Dispute to a mutually
acceptable alternative dispute resolution procedure (which may be non-binding
or binding upon the parties, as they agree in advance) (the "ADR Procedure").
In the event the Indemnifying Party and the Indemnified Party agree upon an ADR
Procedure, such parties shall, in consultation with the chosen dispute
<PAGE>
resolution service (the "ADR Service"), promptly agree upon a format and
timetable for the ADR Procedure, agree upon the rules applicable to the ADR
Procedure, and promptly undertake the ADR Procedure. The provisions of this
Section 8.03(d) shall not obligate the Indemnifying Party and the Indemnified
Party to pursue an ADR Procedure or prevent either such party from pursuing the
Dispute in a court of competent jurisdiction; provided that, if the
Indemnifying Party and the Indemnified Party agree to pursue an ADR Procedure,
neither the Indemnifying Party nor the Indemnified Party may commence
litigation or seek other remedies with respect to the Dispute prior to the
completion of such ADR Procedure. Any ADR Procedure undertaken by the
Indemnifying Party and the Indemnified Party shall be considered a compromise
negotiation for purposes of federal and state rules of evidence, and all
statements, offers, opinions and disclosures (whether written or oral) made in
the course of the ADR Procedure by or on behalf of the Indemnifying Party, the
Indemnified Party or the ADR Service shall be treated as confidential and,
where appropriate, as privileged work product. Such statements, offers,
opinions and disclosures shall not be discoverable or admissible for any
purposes in any litigation or other proceeding relating to the Dispute
(provided that this sentence shall not be construed to exclude from discovery
or admission any matter that is otherwise discoverable or admissible). The fees
and expenses of any ADR Service used by the Indemnifying Party and the
Indemnified Party shall be shared equally by the
Indemnifying Party and the Indemnified Party.

(e)	Notwithstanding the other provisions of this Section 8.03, if a third
party asserts (other than by means of a lawsuit) that an Indemnified Party is
liable to such third party for a monetary or other obligation which may
constitute or result in Losses for which such Indemnified Party may be entitled
to indemnification pursuant to this Section 8, and such Indemnified Party
reasonably determines that it has a valid business reason to fulfill such
obligation, then (i) such Indemnified Party shall be entitled to satisfy such
obligation, without prior notice to or consent from the Indemnifying Party,
(ii) such Indemnified Party may subsequently make a claim for indemnification
in accordance with the provisions of this Section 8, and (iii) such Indemnified
Party shall be reimbursed, in accordance with the provisions of this Section 8,
for any such Losses for which it is entitled to indemnification pursuant to
this Section 8 (subject to the right of the Indemnifying Party to dispute the
Indemnified Party's entitlement to indemnification, or the amount for which it
is entitled to indemnification, under the terms of this Section 8).

8.4 Survival of Representations and Warranties. All representations and
warranties contained in this Agreement, shall (a) survive the Closing and any
investigation at any time made by or on behalf of an Indemnified Party and (b)
shall expire on the date 18 months following the Closing Date, except that (i)
the representations and warranties set forth in Sections 2, 3.1, 3.2, 3.4, 4.1,
4.2, 4.3 and 4.4 shall survive the Closing without limitation, (ii) the
representations and warranties set forth in Sections 3.14, 3.19, 4.16 and 4.19
shall survive until 30 days following expiration of all statutes of limitation
applicable to the matters referred to therein and (iii) the representation and
warranties in Section 3.20 and 4.20 shall survive for two years after the
Closing Date. If an Indemnified Party delivers to an Indemnifying Party, before
expiration of a representation or warranty, either a Claim Notice based upon a
breach of such representation or warranty, or a notice that, as a result a
legal proceeding instituted by or written claim made by a third party, the
Indemnified Party reasonably expects to incur Losses as a result of a breach of
such representation or warranty (an "Expected Claim Notice"), then such
representation or warranty shall survive until, but only for purposes of, the
resolution of the matter covered by such notice. If the legal proceeding or

<PAGE>
written claim with respect to which an Expected Claim Notice has been given is
definitively withdrawn or resolved in favor of the Indemnified Party, the
Indemnified Party shall promptly so notify the Indemnifying Party.

8.5 Limitations.

liability of the Parent, on the one hand, and the Buyer, on the other hand, for
Losses under this Section 8 shall not exceed $7,000,000, and (ii) the Parent

3.19, 3.20, 4.1, 4.2, 4.3, 4.4 , 4.16, 4.19 and 4.20 to a breach of the

warranties. On and after the Closing, the Parent shall have no recourse to, and
no right of contribution from the Company or any Subsidiary, with respect to
any matter whatsoever, including a breach of any representation, warranty,
covenant or agreement set forth in this Agreement.

(b)	Except with respect to claims based on fraud, after the Closing, the
rights of the Indemnified Parties under this Section 8 shall be the exclusive
remedy of the Indemnified Parties with respect to claims resulting from or
relating to any misrepresentation, breach of warranty or failure to perform any
covenant or agreement contained in this Agreement.

9. Tax Matters.

9.1 Preparation and Filing of Tax Returns.

(a)	The Parent shall cause to be prepared and timely filed all Tax Returns
of the Company and the Subsidiaries required to be filed prior to the Closing
Date when such filings are due (taking into account extensions).

(b)	The Buyer shall prepare and timely file or shall cause to be prepared
and timely filed all other Tax Returns with respect to the Company and the
Subsidiaries or in respect of their businesses, assets or operations.

9.2 Tax Indemnification by the Parent.

(a)	In addition to any indemnification provided under Section 8, the Parent
shall indemnify the Buyer in respect of, and hold the Buyer harmless, on an
after-Tax basis, against (x) Losses resulting from, relating to, or
constituting a breach of any representation contained in Section 3.14 hereof,
(y) the failure to perform any covenant or agreement set forth in this Section
9, and (z), without duplication, the following Taxes with respect to the
Company and the Subsidiaries:

(1) Any and all Taxes due and payable by the Company or any Subsidiaries for
any taxable period that ends (or is deemed pursuant to Section 9.3(b) to end)
on or before the Closing Date;



<PAGE>
(2) Any liability of such entities for Taxes of other entities as transferee or
successor or pursuant to any contractual obligation for any period that ends
(or is deemed pursuant to Section 9.3(b) to end) on or before the Closing Date;
and

(3) Any sales, use, transfer, stamp, conveyance, value added, recording,
registration, documentary, filing or other similar Taxes and fees, whether
levied on the Buyer, the Parent, the Company, a Subsidiary or any of their
respective Affiliates, on account of this Agreement or the transactions
contemplated hereby.

(b)	The amounts specified in paragraphs (i), (ii), and (iii) shall be
reduced (but not below zero) by the amount of any accruals for Tax liabilities
on the Current Balance Sheet (exclusive of any accruals for "deferred taxes" or
similar items that reflect timing differences between Tax and financial
accounting principles) and the amounts of any estimated Tax payments made on or
before the Closing Date.

(c)	Amounts payable pursuant to this Section 9.2 shall be computed after
taking into account all Tax consequences to the Buyer (or its Affiliates) of
(i) the receipt of (or the right to receive) the indemnification payment and
(ii) the incurrence of the liability that gave rise to the right to receive the
indemnification payment. Thus, it is the intention of the Parties that the
Buyer be held harmless with respect to the liability that gave rise to the
right to the indemnification payment on an after-Tax basis.

(d)	All claims for indemnification pursuant to this Section 9 shall be made
in accordance with Section 8 hereof.

9.3 Allocation of Certain Taxes.

(a)	The Buyer and the Parent agree that if the Company or any Subsidiary is
permitted but not required under applicable foreign, state or local Tax laws to
treat the Closing Date as the last day of a taxable period, the Buyer and the
Parent shall treat such day as the last day of a taxable period.

(b)	Any Taxes for a taxable period beginning before the Closing Date and
ending after the Closing Date with respect to the Company and/or the
Subsidiaries shall be apportioned for purposes of Section 9.2 between the
portion of the period ending on the Closing Date and the portion of the period
commencing on the day immediately following the Closing Date based on the
actual operations of the Company and/or the Subsidiaries, as the case may be,
during such portions of the periods, and each such portion of such period shall
be deemed to be a taxable period (whether or not it is in fact a taxable
period).

9.4 Cooperation on Tax Matters.

(a)	The Buyer and the Parent and their respective Affiliates shall
cooperate in the preparation of all Tax Returns for any Tax periods for which
one party could reasonably require the assistance of the other party in
obtaining any necessary information. Such cooperation shall include, but not be
limited to, furnishing prior years' Tax Returns or return preparation packages
illustrating previous reporting practices or containing historical information
relevant to the preparation of such Tax Returns, and furnishing such other
information within such party's possession requested by the party filing such
Tax Returns as is relevant to their preparation. Such cooperation and
information also shall include without limitation provision of powers of
attorney for the purpose of signing Tax Returns and defending audits, promptly
<PAGE>
forwarding copies of appropriate notices and forms or other communications
received from or sent to any taxing authority which relate to the Company or
the Subsidiaries, and providing copies of all relevant Tax Returns, together
with accompanying schedules and related workpapers, documents relating to
rulings or other determinations by any taxing authority and records concerning
the ownership and tax basis of property, which the requested party may possess.

(b)	If the Buyer or any of the Company and the Subsidiaries (as the case
may be) on the one hand, or the Parent on the other, fails to provide any
information requested by the other party within a reasonable period, or
otherwise fails to do any act required of it under this Section 9.5, then the
party failing to provide the information or do such act shall be obligated,
notwithstanding any other provision of this Agreement, to indemnify the party
requesting the information or act and shall so indemnify the requesting party
and hold such party harmless from and against any and all costs, claims or
damages, including, without limitation, all Taxes or deficiencies thereof,
payable as a result of such failure. Notwithstanding the foregoing, the party
that failed to deliver the information or do the act requested shall in no
event be obligated to make any payments pursuant to this Section 7.5(b) if such
party used all reasonable commercial efforts to provide the requested
information or perform the requested act.

9.5 Termination of Tax-Sharing Agreements. All Tax-sharing agreements or
similar arrangements with respect to or involving the Company and the
Subsidiaries shall be terminated prior to the Closing Date and, after the
Closing Date, the Company and the Subsidiaries shall not be bound thereby or
have any liability thereunder for amounts due in respect of periods ending on
or before the Closing Date.

9.6 Certain Tax Elections. The Parent shall not elect, cause to be elected, or
participate in any election pursuant to Treasury Regulation Section 1.1502-
76(b)(2) (or any comparable provisions of foreign or state law) to allocate
items of income and expense of the Company and the Subsidiaries between the
taxable year of the Parent ending on the Closing Date and its taxable year
commencing on the day after the Closing Date on a proportionate method based on
the number of days contained in each such taxable year. The Buyer shall not
elect, cause to be elected, or participate in any election pursuant to Section
338(h)(10) or 338(g) with respect to the transactions contemplated herein. The
Buyer shall cooperate with the Parent in reallocation of the Company and the
Subsidiary Net Operating Losses.

10. Post-Closing Agreements.

The Parent and the Buyer agree that from and after the Closing Date:

10.1 Proprietary Information.

(a)	The Parent and each of its affiliates (as such term is defined in the
Securities Act of 1933, as amended, and the rules and regulations promulgated
thereunder) (individually, an "Affiliate" and collectively "Affiliates") shall
hold in confidence and shall use their best efforts to have all officers,
directors and personnel who continue after the Closing to be employed by the
Parent or any Affiliate thereof to hold in confidence all knowledge and
information of a secret or confidential nature with respect to the business of
the Company and the Subsidiaries and not to disclose, publish or make use of
the same without the consent of the Buyer, except to the extent that such
information shall have become public knowledge other than by breach of this
Agreement by the Parent or pursuant to subpoena or court order.

<PAGE>
(b)     If (i) the employment of an officer, director or other employee of the
Parent or any Affiliate thereof, to whom secret or confidential knowledge or
information concerning the business of the Company or the Subsidiaries has been
disclosed, is terminated and (ii) such individual is subject to an obligation
to maintain such knowledge or information in confidence after such termination,
the Parent shall, upon request by the Buyer, take all reasonable steps at their
expense to enforce such confidentiality obligation in the event of an actual or
threatened breach thereof.

(c)	Parent agrees that the remedy at law for any breach of this Subsection
10.1 would be inadequate and that the Buyer shall be entitled to injunctive
relief in addition to any other remedy it may have upon breach of any provision
of this Subsection 10.1.

10.2 No Solicitation or Hiring of Former Employees. Except as provided by law,
for a period of three years after the Closing Date and except that the Parent
may employ James Clemens on a part time basis until September 30, 2003,
provided that such employment date not interfere with Mr. Clemens obligation to
the Buyer, neither Parent nor any Affiliate thereof (including the Parent)
shall (a) solicit any person who was an employee of the Parent or any of the
Subsidiaries on the date hereof or the Closing Date to terminate his employment
with the Buyer (or the Company or any of the Subsidiaries, as the case may be)
or to become an employee of the Parent or Affiliate, or (b) hire any person who
was such an employee on the date hereof or on the Closing Date.

10.3 Non-Competition Agreement.

(a)	For a period of five years after the Closing Date, neither Parent nor
any Subsidiary thereof shall: (i) develop, manufacture, market or sell any
product which competes with any existing or proposed product manufactured by
either the Company or any of the Subsidiaries on or prior to the Closing Date,
or (ii) engage in any business competitive with the business of the Company or
any of the Subsidiaries as conducted on the date hereof or on the Closing Date,
in the United States or any other country in which the Company or any of the
Subsidiaries conducted its business during the two years prior to the Closing
Date.

(b)	The parties hereto agree that the duration and geographic scope of the
non-competition provision set forth in this Subsection 10.3 are reasonable. In
the event that any court of competent jurisdiction determines that the duration
or the geographic scope, or both, are unreasonable and that such provision is
to that extent unenforceable, the parties hereto agree that the provision shall
remain in full force and effect for the greatest time period and in the
greatest area that would not render it unenforceable. The parties intend that
this non-competition provision shall be deemed to be a series of separate
covenants, one for each and every county of each and every state of the United
States of America and each and every political subdivision of each and every
country outside the United States of America where this provision is intended
to be effective. The Parent agrees that damages are an inadequate remedy for
any breach of this provision and that the Buyer shall, whether or not it is
pursuing any potential remedies at law, be entitled to equitable relief in the
form of preliminary and permanent injunctions without bond or other security
upon any actual or threatened breach of this non-competition provision.

10.4 Board Representation.

(a)	The Buyer agrees to nominate and recommend to its shareholders the
election to the Buyer's Board of Directors two person designated by the Parent
and acceptable to the Buyer's Board of Directors acting reasonably (it being
<PAGE>

shall terminate if the Parent does not own five percent (5%) or more of the
Buyer's outstanding Common Stock on or before July 31, 2000 or ceases to own
five percent (5%) or more of the Buyer's outstanding Common Stock thereafter.
The initial nominee to the Buyer's Board of Directors will be Alan Goldberg.

(b)	The Parent agrees to nominate and recommend to its shareholders the
election to the Parent's Board of Directors one person designated by the Buyer.
The initial nominee will be David Eisenhaure. The Parent's obligations under
this Section 10.4 shall terminate if the Purchaser ceases to own five percent
(5%) or more of the Buyer's outstanding Common Stock or the Buyer's obligations
under Section 3.10(a) ceases, whichever occurs first.

(c)	Both parties will endeavor to have the representatives set forth above
elected or appointed to their boards as soon as possible, but in no event later
than December 1, 1999. The Parent shall have no obligation to appoint or elect
the Buyer's nominee to its Board of Directors until the Buyer has appointed or
elected the Parent's nominees to the Buyer's Board of Directors.

10.5 Benefit Transition.

Parent and Buyer shall cooperate to take whatever steps are necessary to
effect, as promptly as practicable after the Closing Date, to the extent
elected by participants, the distribution and direct rollover to Buyer's 401(k)
Plan of the accrued benefit as of the Closing Date of the Company's employees
under the 401(k) Plan. With respect to such rollover: (i) Buyer shall provide

10.6 Co-operation in Financial and Other Reparation.

Each of Parent and Buyer agrees to fully cooperate with each other in (i) the
preparation and audit by the Buyer and its independent public accountants of
financial statements of the Company for such periods as are necessary for the
Buyer to comply with its reporting obligations under the Exchange Act and the
rules and regulations thereunder, (ii) the preparation and audit Parent and its
independent public accountants of the financial statements of the Parent and
its consolidated subsidiaries for the fiscal year ended September 30, 1999,

                          REPRESENTATIONS AND WARRANTIES

2.1	Representations, Warranties and Agreements of the Company. The Company
hereby makes the following representations and warranties to the Purchaser:

a.	Organization and Qualification. The Company is a corporation duly
incorporated, validly existing and in good standing under the laws of the State
of Delaware, with the requisite corporate power and authority to own and use
its properties and assets and to carry on its business as currently conducted.
Except for Beacon Power Corporation ("Beacon") or as set forth on Schedule
2.1(a), the Company has no subsidiaries (collectively, the "Subsidiaries"); it
being agreed that for purposes of this Agreement Beacon is not a subsidiary of
the Company. Each of the Subsidiaries (which, except as provided in the prior
sentence, for purposes of this Agreement means any entity in which the Company,
directly or indirectly, owns the majority of such entity's capital stock or
holds an equivalent equity or similar interest) is a corporation duly
incorporated, validly existing and in good standing under the laws of the
jurisdiction of its incorporation or organization (as applicable), with the
full corporate power and authority to own and use its properties and assets and
to carry on its business as currently conducted. Each of the Company and the
Subsidiaries is duly qualified as a foreign corporation to do business and is
in good standing as a foreign corporation in each jurisdiction in which the
nature of the business conducted or property owned by it makes such
qualification necessary, except where the failure to be so qualified or in good
standing, as the case may be, would not, individually or in the aggregate, (x)
<PAGE>
adversely affect the legality, validity or enforceability of any of this
Agreement or the Transaction Documents (as defined in Section 2.1(b)) or any of
the material transactions contemplated hereby or thereby, (y) have or result in
a material adverse effect on the results of operations, assets, or financial
condition of the Company and its Subsidiaries, taken as a whole or (z) impair
the Company's ability to perform in all material respects on a timely basis its
material obligations under any Transaction Document (any of (x), (y) or (z),
being a "Material Adverse Effect"). The Company has on file with the Securities
Exchange Commission true and correct copies of the Company's Certificate of
Incorporation, as amended and as in effect on the date hereof (the "Certificate
of Incorporation"), and the Company's Bylaws, as in effect on the date hereof
(the "Bylaws").

b.	Authorization; Enforcement. The Company has the requisite corporate
power and authority to enter into and to consummate the transactions
contemplated by this Agreement, the A Warrant, the B Warrant and the
Registration Rights Agreement (collectively, the "Transaction Documents"), and
otherwise to carry out its obligations hereunder and thereunder. The execution
and delivery of each of this Agreement and the Transaction Documents by the
Company and the consummation by it of the transactions contemplated hereby and
thereby have been duly authorized by all necessary corporate action. This
Agreement has been duly executed by the Company and the A Warrant and
Registration Rights Agreement at the Primary Closing will be duly executed by
the Company. Subject to the terms and conditions contained herein, the B
Warrant at the Secondary Closing will be duly executed by the Company. When
delivered in accordance with the terms hereof, the Transaction Documents will
constitute the valid and binding obligation of the Company enforceable against
the Company in accordance with its terms, except as such enforceability may be
limited by applicable bankruptcy, insolvency, reorganization, moratorium,
liquidation or similar laws relating to, or affecting generally the enforcement
of, creditors' rights and remedies or by other equitable principles of general
application and except that rights to indemnification and contribution may be
limited by Federal or state securities laws or public policy relating thereto.

Registration Rights Agreement has been duly executed and delivered by the
Purchaser and constitutes the valid and legally binding obligation of the
Purchaser, enforceable against the Purchaser in accordance with its terms,
subject to bankruptcy, insolvency, fraudulent transfer, reorganization,
moratorium and similar laws of general applicability relating to or affecting
creditors' rights generally and to general principles of equity.

b.	Authorization and Validity; Issuance of Shares. The common stock
issuable upon exercise of the MA Warrant and, when issued, the MB Warrant, will
at all times hereafter continue to be duly authorized and reserved for issuance
and the shares of common stock issued upon the exercise of the MA Warrant, and
when issued, the MB Warrant, will be validly issued, fully paid and
non-assessable, free and clear of all liens, encumbrances, and Purchaser rights
of first refusal, other than liens and encumbrances created by the Company and
will not be subject to any preemptive or similar rights. Assuming the accuracy
of the Company's representations in Section 2.1, the issuance by the Purchaser
of the MA Warrant, the MB Warrant and any shares upon exercise of such warrants
is exempt from registration under the Securities Act.

<PAGE>
c.	Purchaser SEC Documents; Financial Statements.	The Common Stock of the
Purchaser is registered pursuant to Section 12(g) of the Exchange Act. The
Purchaser has filed during its current fiscal year all reports, schedules,
forms, statements and other documents required t be filed by it with the
Commission pursuant to the reporting requirements of the Exchange Act,
including pursuant to Section 13, 14 or 15(d) thereof (the foregoing materials
and financial statements and schedules thereto being collectively referred to
herein as the "Purchaser SEC Documents"), on a timely basis or has received a
valid extension of such time of filing and has filed any such Purchaser SEC
Documents prior to the expiration of any such extension. The Purchaser has
delivered to the Company or its representatives true, complete and accurate
copies of the Purchaser SEC Documents that were not filed pursuant to EDGAR. As
of their respective financial statements of the Purchasers included in the
Purchaser SEC Documents comply as to form in all material respects with
applicable accounting requirements and the published rules and regulations of
the Commission with respect thereto as in effect at the time of filing. Such
financial statements have been prepared in accordance with United States
generally accepted accounting principles applied on a consistent basis during
the periods involved, except as may be otherwise specified in such financial
statements or the notes thereto, and fairly present in all material respects
the financial position of the Purchaser as of and for the dates thereof and the
results of operations and cash flows for the periods then ended, subject, in
the case of unaudited statements, to normal, year-end audit adjustments. The
Purchaser acknowledges that the Company will be trading in the securities of
the Purchaser in reliance on the foregoing representation and warranty.

d.	Disclosure; Absence of Certain Changes.	None of this Agreement, the
Schedules to this Agreement, the Purchaser SEC Documents (as amended to date)
contained as of their respective dates, any untrue statement of a material fact
or omitted to state any material fact necessary in order to make the statements
made herein and therein, in light of the circumstances under which they were
made, not misleading. Except as disclosed in Purchaser SEC Documents files on
EDGAR through the date hereof, since the filing of the Purchaser quarterly
report on Form 10-Q on August 6, 1999, there has been no Material Adverse
Change and no material adverse development in the business, properties,
operations, financial condition, liabilities or results of operations of the
Purchaser. The Purchaser has not taken any steps, and does not currently expect
to take any steps, to seek protection pursuant to any bankruptcy law nor does
the Purchaser or any of its Purchaser Subsidiaries have any knowledge or reason
to believe that its creditors intend to initiate involuntary bankruptcy
proceedings.

e.	Investment Intent. The Purchaser is acquiring the Shares, the A Warrant
and the B Warrant for its own account and not with a present view to or for
distributing or reselling the Shares, the A Warrant, the B Warrant or the
Warrant Shares or any part thereof or interest therein in violation of the
Securities Act; provided, however, that by making the representations herein,
the Purchaser does not agree to hold any of the Shares, the A Warrant, the B
Warrant or the Warrant Shares for any minimum or other specific term and
reserves the right to dispose of the Shares, the A Warrant, the B Warrant or
the Warrant Shares at any time in accordance with or pursuant to a registration
statement or an exemption under the Securities Act.

f.	Purchaser Status. At the time the Purchaser was offered the Shares, the
A Warrant, the B Warrant, and at the Primary Closing Date and Secondary Closing
Date, (i) it was and will be an "accredited investor" as defined in clause
(a)(7) of Rule 501 under the Securities Act and (ii) the Purchaser, either
alone or together with its representatives, had and will have such knowledge,
sophistication and experience in business and financial matters so as to be
<PAGE>
capable of evaluating the merits and risks of the prospective investment in the
Shares and the Warrants.

g.	Reliance. The Purchaser understands and acknowledges that (i) the
Shares, the A Warrant and the B Warrant are being offered and sold to the
Purchaser without registration under the Securities Act in a private placement
that is exempt from the registration provisions of the Securities Act under
Section 4(2) of the Securities Act or Regulation D promulgated thereunder and
(ii) the availability of such exemption depends in part on, and the Company
will rely upon the accuracy and truthfulness of, the representations set forth
in this Section 2.2 and the Purchaser hereby consents to such reliance.

h.	Governmental Review. The Purchaser understands that no United States
federal or state agency or any other government or governmental agency has
passed upon or made any recommendation or endorsement of the Shares, the A
Warrant or the B Warrant.

i. Residency.  The Purchaser is a resident of the State of New York.

The Company acknowledges and agrees that the Purchaser makes no representations
or warranties with respect to the transactions contemplated hereby other than
those specifically set forth in this Section 2.2.


                                    ARTICLE III.

                                  OTHER AGREEMENTS

3.1 Transfer Restrictions.

a.	If the Purchaser should decide to dispose of the Shares, the A Warrant,
the B Warrant or the Warrant Shares held by it, the Purchaser understands and
agrees that it may do so only pursuant to an effective registration statement
under the Securities Act, to the Company or pursuant to an available exemption
from the registration requirements of the Securities Act, including Rule 144
promulgated under the Securities Act ("Rule 144"). In connection with any
transfer of any Shares, A Warrant, B Warrant or Warrant Shares other than
pursuant to an effective registration statement, Rule 144 or to the Company,
the Company may require the transferor thereof to provide to the Company a
written opinion of counsel experienced in the area of United States securities
laws selected by the transferor, the form and substance of which opinion shall
be customary for opinions of counsel in comparable transactions, to the effect
that such transfer does not require registration of such transferred securities
under the Securities Act; provided, however, that if the Shares, A Warrant, B
Warrant or Warrant Shares may be sold pursuant to Rule 144(k), no written
opinion of counsel shall be required from the Purchaser if the Purchaser
provides reasonable assurances that such security can be sold pursuant to Rule
144(k). Notwithstanding the foregoing, the Company hereby consents to and
agrees to register any transfer by the Purchaser to an Affiliate of the
Purchaser, provided that the transferee certifies to the Company that it is an
"accredited investor" as defined in Rule 501(a) under the Securities Act. Any
such transferee shall agree in writing to be bound by the terms of this
Agreement and shall have the rights of a Purchaser under this Agreement and the
Transaction Documents. If the Purchaser provides the Company with an opinion of
counsel, the form and substance of which opinion shall be customary for
opinions of counsel in comparable transactions, to the effect that a public
sale, assignment or transfer of the Shares, A Warrant, B Warrant and the
Warrant Shares may be made without registration under the Securities Act or the
Purchaser provides the Company with reasonable assurances that the Shares, A
<PAGE>
Warrant, B Warrant and the Warrant Shares can be sold pursuant to Rule 144
without any restriction as to the number of securities acquired as of a
particular date that can then be immediately sold, the Company shall permit the
transfer, and, in the case of the Warrant Shares, promptly instruct its
transfer agent to issue one or more certificates in such name and in such
denominations as specified by the Purchaser and without any restrictive legend.
Notwithstanding the foregoing or anything else contained herein to the
contrary, the securities may be pledged as collateral in connection with a bona
fide margin account or other lending arrangement.

b.	The Purchaser agrees to the imprinting by the Company, so long as is
required by this Section 3.1(b), of the following legend on the Shares, the A
Warrant, the B Warrant and the Warrant Shares:

	THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN
	REGISTERED WITH THE SECURITIES AND EXCHANGE
	COMMISSION IN RELIANCE UPON AN EXEMPTION FROM
	REGISTRATION UNDER THE SECURITIES ACT OF 1933, AS
	AMENDED (THE "SECURITIES ACT"), AND, ACCORDINGLY,
	MAY NOT BE OFFERED OR SOLD EXCEPT PURSUANT TO AN
	EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES
	ACT OR PURSUANT TO AN AVAILABLE EXEMPTION FROM, OR IN
	A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS
	OF THE SECURITIES ACT.

Neither the Shares, the A Warrant, the B Warrant nor the Warrant Shares shall
be required to contain the legend set forth above (or any other legend) (i) at
any time after transfer pursuant to a registration statement is effective under
the Securities Act covering such security, (ii) if in the written opinion of
counsel to the Company or the Purchaser experienced in the area of United
States securities laws such legend is not required under applicable
requirements of the Securities Act (including judicial interpretations and
pronouncements issued by the staff of the Commission) or (iii) if such Shares,
the A Warrant, the B Warrant or the Warrant Shares are sold pursuant to Rule
144. When requested, which request will be accompanied by the certificate
representing such shares, the Company agrees that it will provide the Purchaser
with a certificate or certificates representing the Shares, the A Warrant, the
B Warrant or the Warrant Shares, free from such legend at such time as such
legend is no longer required hereunder. If such certificate or certificates had
previously been issued with such a legend or any other legend, the Company
shall, upon request, receive such certificate or certificates free of any
legend.

c.      Notwithstanding the foregoing, the Purchaser's disposition of the
Warrant Shares shall be subject to Suspension Periods (as defined in the
Registration Rights Agreement) set forth in Section 3(r) of the Registration
Rights Agreement.

3.2	Stop Transfer Instruction. The Company may not make any notation on its
records or give instructions to any transfer agent of the Company which enlarge
the restrictions on transfer set forth in Section 3.1.

3.3	Furnishing of Information. Until the Shares, the A Warrant, the B
Warrant or the Warrant Shares have been sold pursuant to a registration
statement under the Securities Act or are eligible for sale pursuant to Rule
144(k), the Company will cause its Shares to continue at all times to be
registered under Section 12(g) of the Exchange Act, will timely file (or obtain
extensions in respect thereof and file within the applicable grace period) all
reports required to be filed by the Company after the date hereof pursuant to
<PAGE>
Section 13, 14 or 15(d) of the Exchange Act and, unless filed by EDGAR,
promptly furnish, but in no event later than two (2) business days after the
filing thereof with the Commission, the Purchaser with true and complete copies
of all such filings, and will not take any action or file any document (whether
or not permitted by the Exchange Act or the rules thereunder) to terminate or
suspend such reporting and filing obligations. Until the Shares, the A Warrant,
the B Warrant or the Warrant Shares have been sold pursuant to a registration
statement under the Securities Act or are eligible for sale pursuant to Rule
144(k), if the Company is not required to file reports pursuant to Section
13(a) or 15(d) of the Exchange Act, it will prepare and furnish to the
Purchaser and make publicly available in accordance with Rule 144(c)
promulgated under the Securities Act annual and quarterly financial statements,
together with a discussion and analysis of such financial statements in form
and substance substantially similar to those that would otherwise be required
to be included in reports required by Section 13(a) or 15(d) of the Exchange
Act, as well as any other information required thereby, in the time period that
such filings would have been required to have been made under the Exchange Act.
The Company further covenants that it will take such further action as any
holder of the Shares, the A Warrant, the B Warrant or the Warrant Shares may
reasonably request, all to the extent required from time to time to enable such
Person to sell the Shares, the A Warrant, the B Warrant or the Warrant Shares
without registration under the Securities Act within the limitation of the
exemptions provided by Rule 144 promulgated under the Securities Act, including
the legal opinion referenced above in Section 3.1(b).

3.4 Blue Sky Laws. In accordance with the Registration Rights Agreement, the
Company shall (i) qualify the Warrant Shares under the securities or "blue sky"
laws of such jurisdictions as the Purchaser may request (or to obtain an
exemption from such qualification), (ii) shall provide evidence of any such
action so taken to the Purchaser on or prior to the Closing Date and (iii)
shall continue such qualification at all times through the resale of all
Warrant Shares, but in any event not past the 4th anniversary of the Closing
Date.

3.5 Integration. The Company shall not sell, offer for sale or solicit offers
to buy or otherwise negotiate in respect of any security (as defined in Section
2 of the Securities Act) that would be integrated with the offer or sale of the
Shares, the A Warrant, the B Warrant or the Warrant Shares in a manner that
would require the registration under the Securities Act or the sale of the
Shares, the A Warrant, the B Warrant or the Warrant Shares to any Purchaser or
cause the offering of such securities to be integrated with any other offering
of securities by the Company for the purpose of any stockholder approval
provision applicable to the Company or its securities.

3.6 Listing and Reservation of Warrant Shares.

a. The Company shall (i) not later than three (3) business days after each
Closing Date prepare and file with Nasdaq (as well as any other national
securities exchange or market on which the Common Stock is then listed) an
additional shares listing application or a letter acceptable to Nasdaq covering
and listing a number of shares of Common Stock which are issued at such Closing
or issuable pursuant to the Warrants issuable at such Closing which is at least
equal to 1 times the maximum number of Warrant Shares then issuable, (ii) take
all steps necessary to cause such shares of Common Stock to be approved for
listing on Nasdaq (as well as on any other national securities exchange or
market on which the Common Stock is then listed) as soon as possible
thereafter, (iii) maintain, so long as any other shares of Common Stock shall
be so listed, such listing of all such Warrant Shares, and (iv) provide to the
Purchaser evidence of such listing. Neither the Company nor any of its
<PAGE>
Subsidiaries shall take any action which may result in the delisting or
suspension of the Common Stock on Nasdaq. Prior to the effectiveness of the
Initial Registration Statement (as defined in the Registration Rights
Agreement), the Company shall promptly provide to the Purchaser copies of any
notices it receives from Nasdaq regarding the continued eligibility of the
Common Stock for listing on such automated quotation system, so long as such
notice does not include material, nonpublic information. The Company shall pay
all fees and expenses in connection with satisfying its obligations under this
Section 3.6(a).

b. The Company at all times shall reserve a sufficient number of shares of its
authorized but unissued Common Stock to provide for 1 times the full exercise
of the outstanding Warrants. If at any time the number of shares of Common
Stock authorized and reserved for issuance is insufficient to cover 100% of the
number of Warrant Shares issued and issuable upon exercise of the Warrants
(based on the Exercise Price (as defined in the Warrants) of the Warrants in
effect from time to time) without regard to any limitation on conversions or
exercises, the Company will promptly take all corporate action necessary to
authorize and reserve 100% of such shares, including, without limitation,
calling a special meeting of stockholders to authorize additional shares to
meet the Company's obligations under this Section 3.6(b), in the case of an
insufficient number of authorized shares, and using its best efforts to obtain
stockholder approval of an increase in such authorized number of shares. In
addition, upon the occurrence of an adjustment of the Exercise Price (as
defined in the Warrant), the Company shall be required to file, within ten (10)
business days of such event, a registration statement covering the product of
1.0 and the number Warrant Shares, less the number of Warrant Shares for which
a registration statement is then effective. The Company shall use its best
efforts to cause such registration statement to be declared effective under the
Securities Act as promptly as possible after the filing thereof, but in any
event on or prior to that date which is one hundred and twenty (120) days after
the filing date thereof. All calculations of the above amount shall be made
without regard to any limitation on exercises of Warrants.

3.7 Notice of Breaches.

a.	The Company and the Purchaser shall give prompt written notice to the
other of any breach by it of any representation, warranty or other agreement
contained in this Agreement or in the Transaction Documents. However, no
disclosure by either party pursuant to this Section 3.7 shall be deemed to cure
any breach of any representation, warranty or other agreement contained herein
or in the Transaction Documents.

b.	Notwithstanding the generality of Section 3.7(a), the Company shall
promptly notify, provided such notification will not constitute material
non-public information, the Purchaser of any notice or claim (written or oral)
that it receives from any lender of the Company or any Subsidiary to the effect
that the consummation of the transactions contemplated hereby and by the
Registration Rights Agreement violates or would violate any written agreement
or understanding between such lender and the Company or any Subsidiary, and the
Company shall promptly furnish by facsimile to the Purchaser a copy of any
written statement in support of or relating to such claim or notice.

c.	The default by any Purchaser of any of its obligations, representations
or warranties under this Agreement or the Transaction Documents shall not be
imputed to, and shall have no effect upon, any other Purchaser or affect the
Companys' obligations under this Agreement or any Transaction Document to any
non-defaulting Purchaser.

<PAGE>
3.8 Form D. The Company agrees to file a Form D with respect to the Shares, A
Warrant and B Warrant as required by Rule 506 under Regulation D and to provide
a copy thereof to the Purchaser promptly after such filing.

3.9	Use of Proceeds. The Company intends to use the proceeds from the sale
of the Common Stock and the exercise of the Warrants (i) to enhance the
Company's ability to satisfy purchase orders that both parties anticipate that
the Company will receive from Plug Power, (ii) otherwise to develop the
Company's module manufacturing capability or (iii) in connection with the
transition and integration of Ling Electronics into the Company's other
operations and not to fund future investment in Beacon Power Corporation. The
Company is free to use the proceeds of the offering for other corporate
purposes if the board of directors of the Company determines that it is in the
best interest of the Company to do so. The Purchaser acknowledges that the
Company may, in the future, acquire cash from other sources and that it may
invest such cash in Beacon Power Corporation. It is not the intention of the
parties to establish an auditable trail between receipt of the proceeds and the
use of such funds.

3.10	Board Representation.

a.	The Company agrees to nominate and recommend to its shareholders the
election to the Company's Board of Directors two person designated by the
Purchaser and acceptable to the Company's Board of Directors acting reasonably
(it being agreed that in acting reasonably the Company's Board of Directors may
consider the desirability of having two members of the Company's Board of
Directors affiliated with the Purchaser). The Company's obligations under this
Section 3.10(a) shall terminate if the Purchaser does not own five percent (5%)
or more on or before July 31, 2000 or ceases to own five percent (5%) or more
of the Company's outstanding Common Stock. The initial nominee to the Company's
Board of Directors will be Alan Goldberg.

b.	The Purchaser agrees to nominate and recommend to its shareholders the
election to the Company's Board of Directors one person designated by the
Company. The initial nominee will be David Eisenhaure. The Purchaser's
obligations under this Section 3.10(b) shall terminate if the Purchaser ceases
to own five percent (5%) or more of the Company's outstanding Common Stock or
the Company's obligations under Section 3.10(a) ceases, whichever occurs first.

c. 	Both parties will endeavor to have the representatives set forth above
elected or appointed to their boards as soon as possible, but in no event later
than December 1, 1999. The Purchaser shall have no obligation to appoint or
elect the Company's nominee to its Board of Directors until the Company has
appointed or elected the Purchaser's nominees to the Company's Board of
Directors.

3.11	Transactions with Affiliates. So long as any Shares, A Warrant or B
Warrant are outstanding, the Company shall not, and shall cause each of its
Subsidiaries not to, enter into, amend, modify or supplement, or permit any
Subsidiary to enter into, amend, modify or supplement, any agreement,
transaction, commitment or arrangement with any of its or any Subsidiary's
officers, directors or persons who were officers or directors at any time
during the previous two years, stockholders who beneficially own 5% or more of
the Common Stock, or Affiliates or any individual related by blood, marriage or
adoption to any such individual or with any entity in which any such entity or
individual owns a 5% or more beneficial interest (each a "Related Party"),
except for (a) customary employment arrangements and benefit programs on
reasonable terms, (b) any agreement, transaction, commitment or arrangement on
an arms-length basis on terms no less favorable than terms which would have
<PAGE>
been obtainable from a Person other than such Related Party, or (c) any
agreement, transaction, commitment or arrangement which is approved by a
majority of the disinterested directors of the Company. For purposes hereof,
any director who is also an officer of the Company or any Subsidiary of the
Company shall not be a disinterested director with respect to any such
agreement, transaction, commitment or arrangement. "Affiliate" for purposes of
this section only means, with respect to any person or entity, another person
or entity that, directly or indirectly, (i) has a 5% or more equity interest in
that person or entity, (ii) has 5% or more common ownership with that person or
entity, (iii) controls that person or entity, or (iv) shares common control
with that person or entity. "Control" or "Controls" for purposes of this
section means that a person or entity has the power, direct or indirect, to
conduct or govern the policies of another person or entity.

3.12	Transfer Agent Instructions. At the Primary Closing the Company shall
issue irrevocable instructions to its transfer agent (and shall issue to any
subsequent transfer agent as required), to issue certificates, registered in
the name of the Purchaser or its respective nominee(s), for the Warrant Shares
issuable pursuant to the A Warrant in such amounts as specified from time to
time by the Purchaser to the Company in a form acceptable to the Purchaser (the
"Primary Closing Irrevocable Transfer Agent Instructions"). At the Secondary
Closing the Company shall issue irrevocable instructions to its transfer agent
(and shall issue to any subsequent transfer agent as required), to issue
certificates, registered in the name of the Purchaser or its respective
nominee(s), for the Warrant Shares issuable pursuant to the B Warrant in such
amounts as specified from time to time by the Purchaser to the Company in a
form acceptable to the Purchaser (the "Secondary Closing Irrevocable Transfer
Agent Instructions"). So long as required pursuant to Section 3.1(b), all such
certificates shall bear the restrictive legend specified in Section 3.1(b) of
this Agreement. The Company warrants that no instruction other than the Primary
Closing Irrevocable Transfer Agent Instructions and the Secondary Closing
Irrevocable Transfer Agent Instructions referred to in this Section 3.12, and
stop transfer instructions to give effect to Section 3.1 hereof (in the case of
the Warrant Shares, prior to registration of the Shares under the Securities
Act) will be given by the Company to its transfer agent and that the Shares,
the A Warrant, the B Warrant or the Warrant Shares shall otherwise be freely
transferable on the books and records of the Company as and to the extent
provided in this Agreement and the Transaction Documents. The Company
acknowledges that a breach by it of its obligations hereunder will cause
irreparable harm to the Purchaser by violating the intent and purpose of the
transactions contemplated hereby. Accordingly, the Company acknowledges that
the remedy at law for a breach of its obligations under this Section 3.12 will
be inadequate and agrees, in the event of a beach or threatened breach by the
Company of the provisions of this Section 3.12, that the Purchaser, shall be
entitled, in addition to all other available remedies, to an order and/or
injunction restraining any breach and requiring immediate issuance and
transfer, without the necessity of showing economic loss and without any bond
or other security being required.

3.13 Press Release; Filing of Form 8-K.  Subject to the provisions of Section
6.10 hereof, prior to the opening of Nasdaq on October 21, 1999, the Company
and the Purchaser shall file a joint press release in form and substance

3.14	Purchaser Transfer Agent Instructions. At the Primary Closing the
Purchaser shall issue irrevocable instructions to its transfer agent (and shall
issue to any subsequent transfer agent as required), to issue certificates,
registered in the name of the Company or its respective nominee(s), for the M
Shares issuable pursuant to the MA Warrant in such amounts as specified from
<PAGE>
time to time by the Company to the Purchaser in a form acceptable to the
Company (the "Primary Closing Irrevocable Transfer Agent Instructions"). At the
Secondary Closing the Purchaser shall issue irrevocable instructions to its
transfer agent (and shall issue to any subsequent transfer agent as required),
to issue certificates, registered in the name of the Company or its respective
nominee(s), for the M Shares issuable pursuant to the MB Warrant in such
amounts as specified from time to time by the Company to the Purchaser in a
form acceptable to the Company (the "Secondary Closing Irrevocable Transfer
Agent Instructions"). So long as required pursuant to Section 3.15(b), all such
certificates shall bear the restrictive legend specified in Section 3.15(b) of
this Agreement. The Purchaser warrants that no instruction other than the
Primary Closing Irrevocable Transfer Agent Instructions and the Secondary
Closing Irrevocable Transfer Agent Instructions referred to in this Section
3.14, and stop transfer instructions to give effect to Section 3.15 hereof (in
the case of the M Shares, prior to registration of the Shares under the
Securities Act) will be given by the Purchaser to its transfer agent and that
the M Shares, the MA Warrant or the MB Warrant shall otherwise be freely
transferable on the books and records of the Purchaser as and to the extent
provided in this Agreement and the Transaction Documents. The Purchaser
acknowledges that a breach by it of its obligations hereunder will cause
irreparable harm to the Company by violating the intent and purpose of the
transactions contemplated hereby. Accordingly, the Purchaser acknowledges that
the remedy at law for a breach of its obligations under this Section 3.14 will
be inadequate and agrees, in the event of a beach or threatened breach by the
Purchaser of the provisions of this Section 3.14, that the Company, shall be
entitled, in addition to all other available remedies, to an order and/or
injunction restraining any breach and requiring immediate issuance and
transfer, without the necessity of showing economic loss and without any bond
or other security being required.

3.15 Purchaser Transfer Restrictions.

a.	If the Company should decide to dispose of the M Shares, the MA Warrant
or the MB Warrant held by it, the Company understands and agrees that it may do
so only pursuant to an effective registration statement under the Securities
Act, to the Company or pursuant to an available exemption from the registration
requirements of the Securities Act, including Rule 144 promulgated under the
Securities Act ("Rule 144"). In connection with any transfer of any M Shares,
MA Warrant or MB Warrant other than pursuant to an effective registration
statement, Rule 144 or to the Purchaser, the Purchaser may require the
transferor thereof to provide to the Purchaser a written opinion of counsel
experienced in the area of United States securities laws selected by the
transferor, the form and substance of which opinion shall be customary for
opinions of counsel in comparable transactions, to the effect that such
transfer does not require registration of such transferred securities under the
Securities Act; provided, however, that if the M Shares, MA Warrant or MB
Warrant may be sold pursuant to Rule 144(k), no written opinion of counsel
shall be required from the Company if the Company provides reasonable
assurances that such security can be sold pursuant to Rule 144(k).
Notwithstanding the foregoing, the Purchaser hereby consents to and agrees to
register any transfer by the Company to an Affiliate of the Company, provided
that the transferee certifies to the Purchaser that it is an "accredited
investor" as defined in Rule 501(a) under the Securities Act. Any such
transferee shall agree in writing to be bound by the terms of this Agreement
and shall have the rights of a Company under this Agreement and the Transaction
Documents. If the Company provides the Purchaser with an opinion of counsel,
the form and substance of which opinion shall be customary for opinions of
counsel in comparable transactions, to the effect that a public sale,
assignment or transfer of the M Shares, MA Warrant and MB Warrant may be made
<PAGE>
without registration under the Securities Act or the Purchaser provides the
Company with reasonable assurances that the M Shares, MA Warrant and the MB
Warrant can be sold pursuant to Rule 144 without any restriction as to the
number of securities acquired as of a particular date that can then be
immediately sold, the Purchaser shall permit the transfer, and, in the case of
the M Shares, promptly instruct its transfer agent to issue one or more
certificates in such name and in such denominations as specified by the Company
and without any restrictive legend. Notwithstanding the foregoing or anything
else contained herein to the contrary, the securities may be pledged as
collateral in connection with a bona fide margin account or other lending
arrangement.

b.	The Company agrees to the imprinting by the Purchaser, so long as is
required by this Section 3.15(b), of the following legend on the M Shares, the
MA Warrant and the MB Warrant:

	THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN
	REGISTERED WITH THE SECURITIES AND EXCHANGE COMMISSION
	IN RELIANCE UPON AN EXEMPTION FROM REGISTRATION UNDER
	THE SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES
	ACT"), AND, ACCORDINGLY, MAY NOT BE OFFERED OR SOLD
	EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT
	UNDER THE SECURITIES ACT OR PURSUANT TO AN AVAILABLE
	EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE
	REGISTRATION REQUIREMENTS OF THE SECURITIES ACT.

Neither the M Shares, the MA Warrant nor the MB Warrant shall be required to
contain the legend set forth above (or any other legend) (i) at any time after
transfer pursuant to a registration statement is effective under the Securities
Act covering such security, (ii) if in the written opinion of counsel to the
Purchaser of the Company experienced in the area of United States securities
laws such legend is not required under applicable requirements of the
Securities Act (including judicial interpretations and pronouncements issued by
the staff of the Commission) or (iii) if such M Shares, the MA Warrant or the
MB Warrant are sold pursuant to Rule 144. When requested, which request will be
accompanied by the certificate representing such shares, the Purchaser agrees
that it will provide the Company with a certificate or certificates
representing the M Shares, the MA Warrant or the MB Warrant, free from such

3.17	Purchaser Furnishing of Information. Until the M Shares, the MA Warrant
or the MB Warrant have been sold pursuant to a registration statement under the
Securities Act or are eligible for sale pursuant to Rule 144(k), the Purchaser
will cause its M Shares to continue at all times to be registered under Section
12(g) of the Exchange Act, will timely file (or obtain extensions in respect
thereof and file within the applicable grace period) all reports required to be
filed by the Purchaser after the date hereof pursuant to Section 13, 14 or
15(d) of the Exchange Act and, unless filed by EDGAR, promptly furnish, but in
no event later than two (2) business days after the filing thereof with the
Commission, the Company with true and complete copies of all such filings, and
will not take any action or file any document (whether or not permitted by the
Exchange Act or the rules thereunder) to terminate or suspend such reporting
<PAGE>
and filing obligations. Until the M Shares, the MA Warrant or the MB Warrant
have been sold pursuant to a registration statement under the Securities Act or
are eligible for sale pursuant to Rule 144(k), if the Purchaser is not required
to file reports pursuant to Section 13(a) or 15(d) of the Exchange Act, it will
prepare and furnish to the Company and make publicly available in accordance
with Rule 144(c) promulgated under the Securities Act annual and quarterly
financial statements, together with a discussion and analysis of such financial
statements in form and substance substantially similar to those that would
otherwise be required to be included in reports required by Section 13(a) or
15(d) of the Exchange Act, as well as any other information required thereby,
in the time period that such filings would have been required to have been made
under the Exchange Act. The Purchaser further covenants that it will take such
further action as any holder of the M Shares, the MA Warrant or the MB Warrant
may reasonably request, all to the extent required from time to time to enable
such Person to sell the M Shares, the MA Warrant or the MB Warrant without
registration under the Securities Act within the limitation of the exemptions
provided by Rule 144 promulgated under the Securities Act, including the legal
opinion referenced above in Section 3.15(b).

3.18	Purchaser Blue Sky Laws. In accordance with the MTI Registration Rights
Agreement, the Purchaser shall (i) qualify the M Shares under the securities or
"blue sky" laws of such jurisdictions as the Company may request (or to obtain
an exemption from such qualification), (ii) shall provide evidence of any such
action so taken to the Company on or prior to the Primary Closing Date and
(iii) shall continue such qualification at all times through the resale of all
M Shares, but in any event not past the 4th anniversary of the Primary Closing
Date.

3.19 Purchaser Listing and Reservation of M Shares.

a.	The Purchaser shall (i) not later than three (3) business days after
each Closing Date prepare and file with Nasdaq (as well as any other national
securities exchange or market on which the common stock is then listed) an
additional shares listing application or a letter acceptable to Nasdaq covering
and listing a number of shares of common stock which are issuable pursuant to
the Warrants issuable at such Closing which is at least equal to 1 times the
maximum number of M Shares then issuable, (ii) take all steps necessary to
cause such shares of common stock to be approved for listing on Nasdaq (as well
as on any other national securities exchange or market on which the Common
Stock is then listed) as soon as possible thereafter, (iii) maintain, so long
as any other shares of common stock shall be so listed, such listing of all
such M Shares, and (iv) provide to the Company evidence of such listing.
Neither the Purchaser nor any of its Subsidiaries shall take any action which
may result in the delisting or suspension of the common stock on Nasdaq. The
Purchaser shall pay all fees and expenses in connection with satisfying its
obligations under this Section 3.19(a).

b.	The Purchaser at all times shall reserve a sufficient number of shares
of its authorized but unissued common stock to provide for 1 times the full
exercise of the outstanding Warrants. If at any time the number of shares of
common stock authorized and reserved for issuance is insufficient to cover 100%
of the number of Warrant Shares issued and issuable upon exercise of the
warrants (based on the Exercise Price (as defined in the Warrants) of the
Warrants in effect from time to time) without regard to any limitation on
conversions or exercises, the Purchaser will promptly take all corporate action
necessary to authorize and reserve 100% of such shares, including, without
limitation, calling a special meeting of stockholders to authorize additional
shares to meet the Company's obligations under this Section 3.19(b), in the
case of an insufficient number of authorized shares, and using its best efforts
<PAGE>
to obtain stockholder approval of an increase in such authorized number of
shares. 3.20	Ordinary Course Brokerage and Trading. The Purchaser represents
and agrees that neither Purchaser, nor any person that is required by internal
policy to pre-clear securities transactions with the Purchaser will, enter into
any short sales of the Company's common stock, except in connection with an
intended sale of common stock, and in such event, only to the extent covered
within seven (7) Trading Days of such short sale. In addition, the Purchaser
represents and agrees on behalf of itself and each of the persons identified in
the preceding sentence that it will not establish a short position or sell any
of the Shares during (i) the twenty (20) Trading Day period prior to the one
(1) year anniversary of the Primary Closing Date or (ii) the seventy five (75)
Trading Days ending on August 28, 2003 and 2006.

handling of any claim, suit, judgment or matter for which indemnify is sought,
which is set forth in the notice sent by the Indemnified Party, by notifying
the Indemnified Party in writing to such effect within fifteen days of receipt
of such notice; provided, however, that the Indemnified Party shall have the
right to employ counsel to represent it if, in the Indemnified Party's
reasonable judgment based upon the advice of counsel, it is advisable in light
of the separate interests of the Indemnified Party, to be represented by
separate counsel, and in that event the reasonable fees and expenses of such
separate counsel shall be paid by the Indemnifying Party. If the Indemnifying
Party does not give timely notice in accordance with the preceding sentence,
the Indemnifying Party shall be deemed to have given notice that it does not
wish to control the handling of such claim, suit or judgment. In the event the
Indemnifying Party elects (by notice in writing within such fifteen day period)
to assume the defense of or otherwise control the handling of any such claim,
suit, judgment or matter for which indemnity is sought, the Indemnifying Party
shall indemnify and hold harmless the Indemnified Party from and against any
and all reasonable professional fees (including attorneys' fees, accountants,
consultants and engineering fees) and investigation expenses incurred by the
Indemnifying Party prior to such election, notwithstanding the fact that the
Indemnifying Party may not have been so liable to the Indemnified Party had the
Indemnifying Party not elected to assume the defense of or to otherwise control
the handling of such claim, suit, judgment or other matter. In the event that
the Indemnifying Party does not assume the defense or otherwise control the
handling of such matter, the Indemnified Party may retain counsel, as an
indemnification expense, to defend such claim, suit, judgment or matter.

(3)	Final Authority. The parties shall cooperate in the defense of any such
claim or litigation and each shall make available all books and records which
are relevant in connection with such claim or litigation. In connection with
any claim, suit or other proceeding with respect to which the Indemnifying
Party has assumed the defense or control, the Indemnifying Party will not
consent to the entry of any judgment or enter into any settlement with respect
to any matter which does not include a provision whereby the plaintiff or
claimant in the matter releases the Indemnified Party from all liability with
<PAGE>
respect thereto, without the written consent of the Indemnified Party. In
connection with any claim, suit or other proceeding with respect to which the
Indemnifying Party has not assumed the defense or control, the Indemnified
Party may not compromise or settle such claim without the consent of the
Indemnifying Party, which shall not be unreasonably withheld and shall be
deemed to have been given if the Indemnified Party provides the Indemnifying
Party with a written notice setting forth the material terms of such compromise
or settlement and the Indemnifying Party does not object thereto in writing
within ten days of its receipt of such notice.

                                  ARTICLE VI.

6.3	Amendments; Waivers. No provision of this Agreement may be waived or
amended except in a written instrument signed, in the case of an amendment, by
both the Company and each of the Purchaser or, in the case of a waiver, by the
party against whom enforcement of any such waiver is sought. No waiver of any
default with respect to any provision, condition or requirement of this
Agreement shall be deemed to be a continuing waiver in the future or a waiver

omission of either party to exercise any right hereunder in any manner impair
the exercise of any such right accruing to it thereafter.

6.4	Headings. The headings herein are for convenience only, do not
constitute a part of this Agreement and shall not be deemed to limit or affect
any of the provisions hereof.

6.5	Successors and Assigns. This Agreement shall be binding upon and inure
to the benefit of the parties and their successors and permitted assigns.
Neither the Company nor the Purchaser may assign this Agreement or any rights
or obligations hereunder without the prior written consent of each of the other

of this Agreement or the Transaction Documents.

6.6	No Third-Party Beneficiaries. This Agreement is intended for the
benefit of the parties hereto and their respective permitted successors and
assigns and is not for the benefit of, nor may any provision hereof be enforced
by, any other Person.

6.7	Governing Law. This Agreement shall be governed by and construed and
enforced in accordance with the internal laws of the State of New York without
regard to the principles of conflicts of law thereof. Each party hereby
irrevocably submits to the nonexclusive jurisdiction of the federal courts
sitting in the City of Albany, County of Albany or if diversity jurisdiction
cannot be obtained, then in the state courts sitting in the City of Albany,
County of Albany for the adjudication of any dispute hereunder or in connection
herewith or with any transaction contemplated hereby or discussed herein, and
hereby irrevocably waives, and agrees not to assert in any suit, action or
proceeding, any claim that it is not personally subject to the jurisdiction of
any such court, that such suit, action or proceeding is improper. Each party
hereby irrevocably waives personal service of process and consents to process
being served in any such suit, action or proceeding by mailing a copy thereof
to such party at the address for such notices to it under this Agreement and
agrees that such service shall constitute good and sufficient service of
process and notice thereof. Nothing contained herein shall be deemed to limit
in any way any right to serve process in any manner permitted by law. EACH
PARTY HEREBY IRREVOCABLY WAIVES ANY RIGHT IT MAY HAVE, AND AGREES NOT TO


<PAGE>
REQUEST, A JURY TRIAL FOR THE ADJUDICATION OF ANY DISPUTE HEREUNDER OR IN
CONNECTION HEREWITH OR ARISING OUT OF THIS AGREEMENT OR ANY TRANSACTION
CONTEMPLATED HEREBY.

6.8	Survival. The representations and warranties of the Company and the
Purchaser contained in Sections 2.1 and 2.2, the agreements and covenants set
forth in Section 3, and the indemnification provisions set forth in Section 5,
shall survive the Closing and any exercise of the A Warrant, the B Warrant and
the M Warrant regardless of any investigation made by or on behalf of the
Purchaser or by or on behalf of the Company, except that, in the case of
representations, warranties and indemnities such survival shall be limited to
the period of 18 months following the Closing Date on which they were made or
deemed to have been made, except for representations in 2.1(a), 2.1(b), 2.1(d),
2.1(i) and 2.1(v) which shall survive for the applicable statute of limitations
and 2.1(j) which shall survive for the period of two (2) years. This section
shall have no effect on the survival of the indemnification provisions of the
Registration Rights Agreement.

6.9	Counterparts. This Agreement may be executed in two or more
counterparts, all of which when taken together shall be considered one and the
same agreement and shall become effective when counterparts have been signed by
each party and delivered to the other party, it being understood that both
parties need not sign the same counterpart. In the event that any signature is
delivered by facsimile transmission, such signature shall create a valid and
binding obligation of the party executing (or on whose behalf such signature is
executed) the same with the same force and effect as if such facsimile
signature page were an original thereof.

6.10	Publicity. The Company and the Purchaser shall consult with each other
in issuing any press releases or otherwise making public statements with
respect to the transactions contemplated hereby and neither party shall issue
any such press release or otherwise make any such public statement without the
prior written consent of the other, which consent shall not be unreasonably
withheld or delayed, except that no prior consent shall be required if such
disclosure is required by law, in which such case the disclosing party shall
provide the other party with prior notice of such public statement. The Company
shall not publicly or otherwise disclose the names of the Purchaser without the
Purchaser's prior written consent. Subject to the Company's review and
approval, the Purchaser and its affiliated companies shall, without further
cost, have the right to use in its advertising, marketing or other similar
materials, the Company's logo and trademarks and all or parts of the Company's
press releases that focus on the Transaction forming the subject matter of this
Agreement or which make reference to the Transaction; provided, however, that
Company approval is not required with regard to formal newspaper announcements
of transactions or "tombstones." The Purchaser understands that this grant by
the Company only waives objections that the Company might have to the use of
such materials by the Purchaser and in no way constitutes a representation by
the Company that references in such materials to the activities of
third-parties have been cleared or constitute a fair use.

6.11	Severability. In case any one or more of the provisions of this
Agreement shall be invalid or unenforceable in any respect, the validity and
enforceability of the remaining terms and provisions of this Agreement shall
not in any way be affected or impaired thereby and the parties will attempt to
agree upon a valid and enforceable provision which shall be a reasonable
substitute therefor, and upon so agreeing, shall incorporate such substitute
provision in this Agreement.


<PAGE>
6.12	Remedies. In addition to being entitled to exercise all rights provided
herein or granted by law, including recovery of damages, the Purchaser will be
entitled to specific performance of the obligations of the Company under this
Agreement or the Transaction Documents without the showing of economic loss and
without any bond or other security being required. The Company and the
Purchaser (severally and not jointly) agree that monetary damages would not be
adequate compensation for any loss incurred by reason of any breach of its
obligations described in the foregoing sentence and hereby agree to waive in
any action for specific performance of any such obligation the defense that a
remedy at law would be adequate.

6.13	Further Assurances. Each party shall do and perform, or cause to be
done and performed, all such further acts and things, and shall execute and
deliver all such other agreements, certificates, instruments and documents, as
the other party may reasonably request in order to carry out the intent and
accomplish the purposes of this Agreement and the consummation of the
transactions contemplated hereby.

6.14	Fees and Expenses. Except as set forth in the Registration Rights
Agreement, each party shall pay the fees and expenses of its advisers, counsel,
accountants and other experts, if any, and all other expenses incurred by such
party incident to the negotiation, preparation, execution, delivery and
performance of this Agreement. The Company shall pay all stamp and other taxes
and duties levied in connection with the issuance of the Warrant Shares
pursuant hereto.

                     MTI REGISTRATION RIGHTS AGREEMENT


This MTI Registration Rights Agreement (this "Agreement") is made and entered
into as of October 21, 1999, between Mechanical Technology Incorporated, a New
York corporation (the "Company"), and SatCon Technology Corporation, a Delaware

		The Company and the Purchasers hereby agree as follows:

or indirectly controls or is controlled by or under common control with such
Person. For the purposes of this definition, "control," when used with respect
to any Person, means the possession, direct or indirect, of the power to direct

the foregoing.

"Indemnifying Party" has the meaning set forth in Section 4(c) hereof.

"Person" means an individual or a corporation, partnership, trust, incorporated
or unincorporated association, joint venture, limited liability company, joint
stock company, government (or an agency or political subdivision thereof) or

"Registrable Securities" means the shares of Common Stock issued or issuable
upon exercise of the Warrants, and any shares of the Company's capital stock
issued as a result of any stock split, stock dividend, recapitalization,
exchange or similar event; provided, that Registrable Securities shall not
include any such shares that are eligible for sale under Rule 144(k).

"Registration Statement" means the Initial Registration Statement and any
additional registration statements contemplated by Section 3, including (in
each case) the Prospectus, amendments and supplements to such registration
statement or Prospectus, including pre- and post-effective amendments, all
exhibits thereto, and all material incorporated by reference in such
registration statement.
<PAGE>
"Rule 144" means Rule 144 promulgated by the Commission pursuant to the
Securities Act, as such Rule may be amended from time to time, or any similar
rule or regulation hereafter adopted by the Commission having substantially the
same effect as such Rule.

"Rule 158" means Rule 158 promulgated by the Commission pursuant to the
Securities Act, as such Rule may be amended from time to time, or any similar
rule or regulation hereafter adopted by the Commission having substantially the
same effect as such Rule.

"Rule 415" means Rule 415 promulgated by the Commission pursuant to the
Securities Act, as such Rule may be amended from time to time, or any similar
rule or regulation hereafter adopted by the Commission having substantially the
same effect as such Rule.

the Warrants.

connection with which securities of the Company are sold to an underwriter for
reoffering to the public pursuant to an effective registration statement.

"Warrants" means the warrants issuable to the Purchaser pursuant to the
Purchase Agreement.

2. Piggyback Registrations. Except as provided herein if, at any time when
there is not an effective Registration Statement covering the Registrable
Securities, the Company shall determine to prepare and file with the Commission
a registration statement relating to an offering for its own account or the
account of others under the Securities Act of any of its equity securities,
other than on Form S-2 (but only in connection with a rights offering), S-4 or
Form S- 8 (each as promulgated under the Securities Act) or their then
equivalents relating to equity securities to be issued solely to existing
shareholders or solely in connection with any acquisition of any entity or
business or equity securities issuable in connection with stock option or other
employee benefit plans, the Company shall send to each Holder of Registrable
Securities written notice of such determination and, if within ten (10) days
after receipt of such notice, any such Holder shall so request in writing,
(which request shall specify the Registrable Securities intended to be disposed
of by the Purchasers), the Company will use reasonable efforts to effect the
registration under the Securities Act of all Registrable Securities which the
Company has been so requested to register by the Holder, to the extent
requisite to permit the disposition of the Registrable Securities so to be
registered, provided that if at any time after giving written notice of its
intention to register any securities and prior to the effective date of the
registration statement filed in connection with such registration, the Company
shall determine for any reason not to register or to delay registration of such
securities, the Company may, at its election, give written notice of such
determination to such Holder and, thereupon, (i) in the case of a determination
not to register, shall be relieved of its obligation to register any
Registrable Securities in connection with such registration (but not from its
obligation to pay expenses in accordance with this Agreement), and (ii) in the
case of a determination to delay registering, shall be permitted to delay
registering any Registrable Securities being registered pursuant to this
<PAGE>
Section 2 for the same period as the delay in registering such other
securities. The Company shall include in such registration statement all or any
part of such Registrable Securities such Holder requests to be registered;
provided, however, that the Company shall not be required to register any
Registrable Securities pursuant to this Section 2 that are eligible for sale
pursuant to Rule 144(k) of the Securities Act. In the case of an underwritten
public offering, if the managing underwriter(s) or underwriter(s) should
reasonably object to the inclusion of the Registrable Securities in such
registration statement, then if the Company after consultation with the
Underwriter's representative should reasonably determine that the inclusion of
such Registrable Securities would materially adversely affect the offering
contemplated in such registration statement, and based on such determination
recommends inclusion in such registration statement of fewer Registrable
Securities then proposed to be sold by the Holders, then (x) the number of
Registrable Securities of the Holder and other holders of piggy-back
registration rights included in such registration statement shall be reduced
pro rata among such Holders and other holders of piggy-back registration rights
(based upon the number of Registrable Securities requested to be included in
the registration) or, in the case of other holders of piggy-back registration
rights, in the manner provided for in that applicable agreement, or (y) none of
the Registrable Securities of the Holders shall be included in such
registration statement if the Company, after consultation with the
underwriter(s), recommends the inclusion of none of such Registrable
Securities; provided, however, that if securities are being offered for the
account of other persons or entities as well as the Company, such reduction
shall not represent a greater fraction of the number of Registrable Securities
intended to be offered by the Holders than the fraction of similar reductions
imposed on such other persons or entities (other than the Company).

3.	Registration Expenses. In the event of a registration described in
Section 2, all reasonable expenses of registration and of the offering effected
thereby of any Holder of Registrable Securities participating in the offering,
including, without limitation, printing expenses, fees and disbursements of
counsel and independent public accountants, counsel to the holders fees and
expenses (including counsel fees incurred in connection with complying with
state securities or "blue sky" laws, fees of the National Association of
Securities Dealers, Inc. and fees of transfer agents and registrars), shall be
borne by the Company, except that each Holder of Registrable Securities shall
bear underwriting commissions, individual counsel fees, if any, and discounts
attributable to such Holder's Registrable Securities being registered.

4.	Further Obligations of the Company. Whenever, under the preceding
sections of this Agreement, the Company is required hereunder to register
Registrable Securities, it agrees that it shall also do the following:

(a)	Unless and until the distribution of all Registrable Securities
requested to be registered under section 2 above is complete, diligently
prepare for filing with the Commission a registration statement and such
amendments and supplements to said registration statement and the prospectus
used in connection therewith as may be necessary to keep said registration
statement effective for a period of at least 120 days and to comply with the
provisions of the Securities Act with respect to the sale of securities covered
by said registration statement for the period necessary to complete the
proposed public offering;

(b)	Furnish to any selling Holder of Registrable Securities such copies of
each preliminary and final prospectus and such other documents as such Holder
may reasonably request to facilitate the public offering of its Registrable
Securities;
<PAGE>
(c) Enter into any underwriting agreement with provisions reasonably required
by the proposed underwriter for the selling Holder of Registrable Securities,
if any, and reasonably acceptable to the Company; and

(d) Register or qualify the Registrable Securities covered by said registration
statement under the securities or "blue-sky" laws of such jurisdictions as the
selling Holder of Registrable Securities may reasonably request.

5.	Indemnification

(a)	Indemnification by the Company. The Company shall, notwithstanding any
termination of this Agreement, indemnify and hold harmless each Holder, the
officers, directors, agents (including any underwriters retained by such Holder
in connection with the offer and sale of Registrable Securities), investment
advisors and employees of each of them, each Person who controls any such
Holder (within the meaning of Section 15 of the Securities Act or Section 20 of
the Exchange Act) and the officers, directors, agents and employees of each
such controlling Person, to the fullest extent permitted by applicable law,
from and against any and all joint or several losses, claims, damages,
liabilities, costs (including, without limitation, costs of preparation and
attorneys' fees) and expenses (collectively, together with actions, proceedings
or inquiries by any regulatory or self-regulatory organization, whether
commenced or threatened, "Losses"), as incurred, arising out of or relating to
(i) any untrue or alleged untrue statement of a material fact contained in the
Registration Statement, any Prospectus or any form of prospectus or in any
amendment or supplement thereto or in any preliminary Prospectus, or arising
out of or relating to any omission or alleged omission of a material fact
required to be stated therein or necessary to make the statements therein (in
the case of any Prospectus or form of prospectus or supplement thereto, in
light of the circumstances under which they were made) not misleading (in the
case of any Prospectus or form of prospectus or supplement thereto, in light of
the circumstances under which they were made), except to the extent, but only
to the extent, that such untrue statements or omissions are based upon and in
conformity with information regarding such Holder furnished in writing to the
Company by such Holder expressly for use therein, or (ii) any violation or
alleged violation by the Company of the Securities Act, the Exchange Act, any
other law, including, without limitation, any state securities law, or any rule
or regulation thereunder relating to the offer or sale of Registrable
Securities, provided, however, that the Company shall not be required to
indemnify any person with respect to a loss arising out of a sale of any
Registrable Securities during any period during which the Company has advised
the Holder to suspend sales pursuant to a registration statement. The Company
shall not, however, be liable for any Losses to any Holder with respect to any
untrue or alleged untrue statement of material fact or omission or alleged
omission of material fact if such statement or omission was made in a
preliminary Prospectus and such Holder did not receive a copy of the final
Prospectus (or any amendment or supplement thereto) at or prior to the
confirmation of the sale of the Registrable Securities in any case where such
delivery is required by the Securities Act and the untrue or alleged untrue
statement of material fact or omission or alleged omission of material fact
contained in such preliminary Prospectus was corrected in the final Prospectus
(or any amendment or supplement thereto) and such final prospectus was provided
by the Company to the Holder prior to the time of such sale. The Company shall
notify the Holders promptly of the institution, threat or assertion of any
Proceeding of which the Company is aware in connection with the transactions
contemplated by this Agreement.

(b)	Indemnification by Holder. The Holder shall indemnify and hold harmless
the Company, the directors, officers, agents and employees, each Person who
<PAGE>
controls the Company (within the meaning of Section 15 of the Securities Act
and Section 20 of the Exchange Act), and the directors, officers, agents or
employees of such controlling Persons, to the fullest extent permitted by
applicable law, from and against all Losses, as incurred, arising solely out of
or based solely upon (i) any untrue statement of a material fact contained in
the Registration Statement, any Prospectus, or any form of prospectus, or
arising solely out of or based solely upon any omission of a material fact
required to be stated therein or necessary to make the statements therein not
misleading to the extent, but only to the extent, that such untrue statement or
omission is contained in any information so furnished in writing by such Holder
to the Company specifically for inclusion in the Registration Statement or such
Prospectus and that such information was reasonably relied upon by the Company
for use in the Registration Statement, such Prospectus or such form of
prospectus or to the extent that such information relates to such Holder or
such Holder's proposed method of distribution of Registrable Securities and was
reviewed and expressly approved in writing by such Holder expressly for use in
the Registration Statement, such Prospectus or such form of prospectus or (ii)
any violation or alleged violation by the Holders of the Securities Act, the
Exchange Act, any other law, including, without limitation, any state
securities law, or any rule or regulation thereunder relating to the offer or
sale of Registrable Securities; provided, however, that the indemnity agreement
contained in this Section 4(b) shall not apply to amounts paid in settlement of
any Losses if such settlement is effected without the prior written consent of
such Holder. In no event shall the liability of any selling Holder hereunder be
greater in amount than the dollar amount of the net proceeds received by such
Holder upon the sale of the Registrable Securities giving rise to such
indemnification obligation.

(c)	Conduct of Indemnification Proceedings. If any Proceeding shall be
brought or asserted against any Person entitled to indemnity hereunder (an
"Indemnified Party"), such Indemnified Party promptly shall notify the Person
from whom indemnity is sought (the "Indemnifying Party") in writing, and the
Indemnifying Party shall assume the defense thereof, including the employment
of counsel reasonably satisfactory to the Indemnified Party and the payment of
all fees and expenses incurred in connection with defense thereof; provided,
however, that the failure of any Indemnified Party to give such notice shall
not relieve the Indemnifying Party of its obligations or liabilities pursuant
to this Agreement, except (and only) to the extent that it shall be finally
determined by a court of competent jurisdiction (which determination is not
subject to appeal or further review) that such failure shall have proximately
and materially adversely prejudiced the Indemnifying Party.

An Indemnified Party shall have the right to employ separate counsel in any
such Proceeding and to participate in the defense thereof, but the fees and
expenses of such counsel shall be at the expense of such Indemnified Party or
Parties unless: (1) the Indemnifying Party has agreed in writing to pay such
fees and expenses; or (2) the Indemnifying Party shall have failed promptly to
assume the defense of such Proceeding and to employ counsel reasonably
satisfactory to such Indemnified Party in any such Proceeding; or (3) the named
parties to any such Proceeding (including any impleaded parties) include both
such Indemnified Party and the Indemnifying Party, and such Indemnified Party
shall have been advised by counsel that a conflict of interest is likely to
exist if the same counsel were to represent such Indemnified Party and the
Indemnifying Party (in which case, if such Indemnified Party notifies the
Indemnifying Party in writing that it elects to employ separate counsel at the
expense of the Indemnifying Party, the Indemnifying Party shall not have the
right to assume the defense thereof and such counsel shall be at the expense of
the Indemnifying Party). The Indemnifying Party shall not be liable for any
settlement of any such Proceeding effected without its written consent, which
<PAGE>
consent shall not be unreasonably withheld. No Indemnifying Party shall,
without the prior written consent of the Indemnified Party, effect any
settlement of any pending Proceeding in respect of which any Indemnified Party
is a party, unless such settlement includes an unconditional release of such
Indemnified Party from all liability on claims that are the subject matter of
such Proceeding.

All fees and expenses of the Indemnified Party (including reasonable fees and
expenses to the extent incurred in connection with investigating or preparing
to defend such Proceeding in a manner not inconsistent with this Section) shall
be paid to the Indemnified Party, as incurred, within ten (10) Business Days of
written notice thereof to the Indemnifying Party (regardless of whether it is
ultimately determined that an Indemnified Party is not entitled to
indemnification hereunder; provided, that the Indemnifying Party may require
such Indemnified Party to undertake to reimburse all such fees and expenses to
the extent it is finally judicially determined that such Indemnified Party is
not entitled to indemnification hereunder).

(d)	Contribution. If a claim for indemnification under Section 4(a) or 4(b)
is unavailable to an Indemnified Party because of a failure or refusal of a
court of competent jurisdiction to enforce such indemnification in accordance
with its terms (by reason of public policy or otherwise), then each
Indemnifying Party, in lieu of indemnifying such Indemnified Party, shall
contribute to the amount paid or payable by such Indemnified Party as a result
of such Losses, in such proportion as is appropriate to reflect the relative
fault of the Indemnifying Party and Indemnified Party in connection with the
actions, statements or omissions that resulted in such Losses as well as any
other relevant equitable considerations. The relative fault of such
Indemnifying Party and Indemnified Party shall be determined by reference to,
among other things, whether any action in question, including any untrue or
alleged untrue statement of a material fact or omission or alleged omission of
a material fact, has been taken or made by, or relates to information supplied
by, such Indemnifying Party or Indemnified Party, and the parties' relative
intent, knowledge, access to information and opportunity to correct or prevent
such action, statement or omission. The amount paid or payable by a party as a
result of any Losses shall be deemed to include, subject to the limitations set
forth in Section 4(c), any reasonable attorneys' or other reasonable fees or
expenses incurred by such party in connection with any Proceeding to the extent
such party would have been indemnified for such fees or expenses if the
indemnification provided for in this Section was available to such party in
accordance with its terms. In no event shall any selling Holder be required to
contribute an amount under this Section 4(d) in excess of the net proceeds
received by such Holder upon sale of the Registrable Securities pursuant to the
Registration Statement giving rise to such contribution obligation.

The parties hereto agree that it would not be just and equitable if
contribution pursuant to this Section 4(d) were determined by pro rata
allocation or by any other method of allocation that does not take into account
the equitable considerations referred to in the immediately preceding
paragraph. No Person guilty of fraudulent misrepresentation (within the meaning
of Section 11(f) of the Securities Act) shall be entitled to contribution from
any Person who was not guilty of such fraudulent misrepresentation.

The indemnity and contribution agreements contained in this Section are in
addition to any liability that the Indemnifying Parties may have to the
Indemnified Parties.

6.      Rule 144.

During the period commencing on the date hereof and ending on the second
anniversary of the Secondary Closing (as defined in the Purchase Agreement), as
long as any Holder owns Registrable Securities, the Company covenants to timely
file (or obtain extensions in respect thereof and file within the applicable
grace period) all reports required to be filed by the Company after the date
hereof pursuant to Section 13(a) or l5(d) of the Exchange Act. During the
period commencing on the date hereof and ending on the second anniversary of
the Secondary Closing (as defined in the Purchase Agreement), as long as any
Holder owns Registrable Securities, if the Company is not required to file
reports pursuant to Section 13(a) or l5(d) of the Exchange Act, it will prepare
and furnish to the Holders and make publicly available in accordance with Rule
144(c) promulgated under the Securities Act annual and quarterly financial
statements, together with a discussion and analysis of such financial
statements in form and substance substantially similar to those that would
otherwise be required to be included in reports required by Section 13(a) or
15(d) of the Exchange Act, as well as any other information required thereby,
in the time period that such filings would have been required to have been made
under the Exchange Act. The Company further covenants that it will use
commercially reasonable efforts to take such further action as any Holder may
reasonably request, all to the extent required from time to time to enable such
Person to sell Underlying Shares without registration under the Securities Act
within the limitation of the exemptions provided by Rule 144 promulgated under
the Securities Act, including requesting of its counsel to provide any legal
opinions referred to in the Purchase Agreement. Upon the request of any Holder,
the Company shall deliver to such Holder a written certification of a duly
authorized officer as to whether it has complied with such requirements of this
Section 5.

	7.	Miscellaneous

(a)	Remedies. In the event of a breach by the Company or by a Holder of any
of their obligations under this Agreement, each Holder or the Company, as the
case may be, in addition to being entitled to exercise all rights granted by
law and under this Agreement, including recovery of damages, will be entitled
to specific performance of its rights under this Agreement. The Company and
each Holder agree that monetary damages would not provide adequate compensation
for any losses incurred by reason of a breach by it of any of the provisions of
this Agreement and hereby further agrees that, in the event of any action for
specific performance in respect of such breach, it shall waive the defense that
a remedy at law would be adequate.

(b)	No Inconsistent Agreements. Neither the Company nor any of its
subsidiaries has, as of the date hereof, nor shall the Company or any of its
subsidiaries, on or after the date of this Agreement, enter into any agreement
with respect to its securities that is inconsistent with the rights granted to
the Holder in this Agreement or otherwise conflicts with or limits the
provisions hereof. Neither the Company nor any of its subsidiaries currently
has in force or effect any agreement granting any registration rights with
respect to any of its securities to any Person. This Agreement, together with

Securities that are owned, directly or indirectly, by the Company, or an
Affiliate of the Company are not deemed outstanding. Notwithstanding the
foregoing, a waiver or consent to depart from the provisions hereof with
respect to a matter that relates exclusively to the rights of Holder and that
does not directly or indirectly affect the rights of other Holder may be given
by Holders of at least a majority of the Registrable Securities to which such
waiver or consent relates; provided, however, that the provisions of this

Persons as permitted under the Purchase Agreement. In addition, the rights of
the Holder hereunder, including the right to have the Company register for
resale Registrable Securities in accordance with the terms of this Agreement,

writing with the transferee or assignee to assign such rights, and a copy of
such agreement is furnished to the Company within a reasonable time after such
assignment, (ii) the Company is, within a reasonable time after such transfer
or assignment, furnished with written notice of (a) the name and address of

assignee agrees in writing with the Company to be bound by all of the
provisions of this Agreement, and (v) such transfer shall have been made in
accordance with the applicable requirements of the Purchase Agreement. The
rights to assignment shall apply to the Holders (and to subsequent) successors
and assigns.

<PAGE>
(f)	Counterparts. This Agreement may be executed in any number of
counterparts, each of which when so executed shall be deemed to be an original
and all of which taken together shall constitute one and the same Agreement. In
the event that any signature is delivered by facsimile transmission, such
signature shall create a valid and binding obligation of the party executing
(or on whose behalf such signature is executed) the same with the same force
and effect as if such facsimile signature were the original thereof.

(g)	Governing Law. The corporate laws of the State of New York shall govern
all issues concerning the relative rights of the Company and the Purchaser as
its stockholders. All other questions concerning the construction, validity,
enforcement and interpretation of this Agreement shall be governed by and
construed in accordance with the laws of the State of New York, without regard
to principles of conflicts of law. Each party hereby irrevocably submits to the
non-exclusive jurisdiction of the federal courts sitting in the City of Albany,
County of Albany, or if diversity jurisdiction cannot be obtained, then in the
state courts sitting in the City of Albany, County of Albany, for the
adjudication of any dispute hereunder or in connection herewith or with any
transaction contemplated hereby or discussed herein, and hereby irrevocably
waives, and agrees not to assert in any suit, action or proceeding, any claim
that it is not personally subject to the jurisdiction of any such court, that
such suit, action or proceeding is improper. Each party hereby irrevocably
waives personal service of process and consent to process being served in any
such suit, action or proceeding by mailing a copy thereof to such party at the
address for such notices to it under this Agreement and agrees that such
service shall constitute good and sufficient service of process and notice
thereof. Nothing contained herein shall be deemed to limit in any way any right
to serve process in any manner permitted by law.

(h)	Cumulative Remedies. The remedies provided herein are cumulative and
not exclusive of any remedies provided by law.

(i)	Severability. If any term, provision, covenant or restriction of this
Agreement is held by a court of competent jurisdiction to be invalid, illegal,
void or unenforceable, the remainder of the terms, provisions, covenants and
restrictions set forth herein shall remain in full force and effect and shall
in no way be affected, impaired or invalidated, and the parties hereto shall
use their reasonable efforts to find and employ an alternative means to achieve
the same or substantially the same result as that contemplated by such term,
provision, covenant or restriction. It is hereby stipulated and declared to be
the intention of the parties that they would have executed the remaining terms,
provisions, covenants and restrictions without including any of such that may
be hereafter declared invalid, illegal, void or unenforceable.

(j)	Headings. The headings in this Agreement are for convenience of
reference only and shall not limit or otherwise affect the meaning hereof.

(k)	Shares Held by The Company and its Affiliates. Whenever the consent or
approval of Holders of a specified percentage of Registrable Securities is
required hereunder, Registrable Securities held by the Company or its
Affiliates (other than any Holder or transferees or successors or assigns
thereof if such Holder is deemed to be an Affiliate solely by reason of its
holdings of such Registrable Securities) shall not be counted in determining
whether such consent or approval was given by the Holders of such required
percentage.

(l)	Revision of SEC Position on Warrants. In the event the rules and
regulations of the Commission or the policies of the staff of the Commission
are modified and as a result thereof the Company determines in good faith that
<PAGE>
it may be practicable and in the interests of the Company and the Holders to
register the exercise of the Warrants so that the Warrant Shares may be freely
resold without maintaining an effective registration statement under the
Securities Act for resales, the Company and the Holders agree to cooperate in
good faith to effect such amendments to this Agreement as may be appropriate to
provide that the Company may fulfill its obligations hereunder with respect to
the Warrants and the Warrant Shares by maintaining an effective registration
statement under the Securities Act covering the exercise of the Warrants rather
than the resale of the Warrant Shares.

IN WITNESS WHEREOF, the parties have executed this MTI Registration Rights
Agreement as of the date first written above.

issued to the Purchaser on such closing date for an offering to be made on a

The Initial Registration Statement shall be on Form S-3 or any successor form

Registrable Securities on Form S-3, in which case such registration shall be on
another appropriate form in accordance herewith, subject to the reasonable

shall (i) not permit any securities other than the Registrable Securities and
securities with respect to which there are outstanding demand or "piggy-back"
registration rights as of the date of filing of each Initial Registration
Statement to be included in the Initial Registration Statement and (ii) use
commercially reasonable efforts to cause the Initial Registration Statement to
be declared effective under the Securities Act as promptly as possible after the
filing thereof, and prior to the Effectiveness Date, and, except as provided

Initial Registration Statement is declared effective by the Commission or such

Registration Statement have been sold or may be sold without volume restrictions
<PAGE>

written opinion letter, addressed to the Holders and the Company's transfer
agent to such effect (the "Effectiveness Period"). The number of shares of
Common Stock initially included in the Initial Registration Statement with
respect to each closing shall be the sum of the number of Securities and shares
of Common Stock that are then issuable upon the exercise of the Warrants which
were issued by the Company at such closing, without regard to any limitation on
the Investor's ability to exercise the Warrants. If at any time the number of
shares of Common Stock issuable pursuant to the Warrant is adjusted in
accordance with the terms thereof, and more shares are issuable pursuant to the
Warrants than remain available for sale pursuant to the Initial Registration
Statement, the Company shall immediately, but in no more than five (5) Business
Days, file a Registration Statement sufficient to register such additional
shares of Common Stock.

(b)	Form S-3 Eligibility. The Company represents and warrants that it
currently meets the registrant eligibility and transaction requirements for the
use of Form S-3 (for primary and secondary offerings) for the registration of
the sale of Registrable Securities by the Purchasers and any other Holders and
the Company shall file all reports required to be filed by the Company with the
Commission in a timely manner so as to maintain such eligibility for the use of
Form S-3.

Simpson Agreement, the Company shall:

(a)	Preparation of Registration Statement. Prepare and file with the
Commission on or prior to each Filing Date a Registration Statement on Form S-3

Distribution substantially in the form of Exhibit A annexed hereto.

(b)	Amendments. (i) Prepare and file with the Commission such amendments,

necessary to keep the Registration Statement continuously effective for the
Effectiveness Period and prepare and file with the Commission such additional
Registration Statements in order to register for resale under the Securities
Act all of the Registrable Securities; (ii) cause the related Prospectus to be
amended or supplemented by any required Prospectus supplement, and as so
supplemented or amended to be filed pursuant to Rule 424 (or any similar
provisions then in force) promulgated under the Securities Act; (iii) respond
as promptly as possible to any comments received from the Commission with
respect to the Registration Statement or any amendment thereto and as promptly
as possible provide the Holders true and complete copies of all correspondence
from and to the Commission relating to the Registration Statement; and (iv)
comply in all material respects with the provisions of the Securities Act and
the Exchange Act with respect to the disposition of all Registrable Securities
covered by the Registration Statement during the applicable period in
accordance with the intended methods of disposition by the Holders thereof set
forth in the Registration Statement as so amended or in such Prospectus as so
supplemented.


<PAGE>
(c)	Notifications. Notify the Holders of Registrable Securities to be sold,
as promptly as possible (and, in the case of (i)(A) below, not less than five
(5) days prior to such filing and, in the case of (i)(C) below, not later than
the first Business Day after effectiveness) and (if requested by any such
Person) confirm such notice in writing no later than one (1) Business Day
following the day (i)(A) when a Prospectus or any Prospectus supplement or
post- effective amendment to the Registration Statement is proposed to be
filed; (B) when the Commission notifies the Company whether there will be a
"review" of such Registration Statement and whenever the Commission comments in
writing on such Registration Statement and (C) with respect to the Registration
Statement or any post-effective amendment, when the same has become effective;
(ii) of any request by the Commission or any other Federal or state
governmental authority for amendments or supplements to the Registration
Statement or Prospectus or for additional information; (iii) of the issuance by
the Commission of any stop order suspending the effectiveness of the
Registration Statement covering any or all of the Registrable Securities or the
initiation of any Proceedings for that purpose; (iv) of the receipt by the
Company of any notification with respect to the suspension of the qualification
or exemption from qualification of any of the Registrable Securities for sale
in any jurisdiction, or the initiation or threatening of any Proceeding for
such purpose; and (vi) of the occurrence of any event that makes any statement
made in the Registration Statement or Prospectus or any document incorporated
or deemed to be incorporated therein by reference untrue in any material
respect or that requires any revisions to the Registration Statement,
Prospectus or other documents so that, in the case of the Registration
Statement or the Prospectus, as the case may be, it will not contain any untrue
statement of a material fact or omit to state any material fact required to be
stated therein or necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading.

(d)	Suspensions. Use its reasonable efforts to avoid the issuance of, or,
if issued, obtain the withdrawal of (i) any order suspending the effectiveness
of the Registration Statement or (ii) any suspension of the qualification (or
exemption from qualification) of any of the Registrable Securities for sale in

underwriter or the Holders of a majority in interest of the Registrable
Securities to be sold in connection with an Underwritten Offering, (i) promptly
incorporate in a Prospectus supplement or post-effective amendment to the
Registration Statement such information as the Company reasonably agrees should
be included therein and (ii) make all required filings of such Prospectus
supplement or such post-effective amendment as soon as practicable after the
Company has received notification of the matters to be incorporated in such
Prospectus supplement or post-effective amendment; provided, however, that the
Company shall not be required to take any action pursuant to this Section 3(e)
that would, in the opinion of counsel for the Company, violate applicable law
or if the Holders of a majority of the Registrable Securities consent to the
delay in taking, or the failure to take, any such action, which consent shall
not be unreasonably withheld.

(f)	Copies of Registration Statement. Furnish to each Holder, without
charge, at least one conformed copy of each Registration Statement and each
amendment thereto, including financial statements and schedules, all documents
incorporated or deemed to be incorporated therein by reference, and all
exhibits to the extent requested by such Person (including those previously
furnished or incorporated by reference) promptly after the filing of such
documents with the Commission.

<PAGE>
(g)	Copies of Prospectus. Promptly deliver to each Holder, without charge,
as many copies of the Prospectus or Prospectuses (including each form of
prospectus) and each amendment or supplement thereto as such Persons may
reasonably request; and the Company hereby consents to the use of such
Prospectus and each amendment or supplement thereto by each of the selling
Holders and any underwriters in connection with the offering and sale of the
Registrable Securities covered by such Prospectus and any amendment or
supplement thereto.

(h)	Blue Sky. Prior to any public offering of Registrable Securities, use
commercially reasonable efforts to register or qualify or cooperate with the
selling Holders, in connection with the registration or qualification (or
exemption from such registration or qualification) of such Registrable
Securities for offer and sale under the securities or Blue Sky laws of such
jurisdictions within the United States as any Holder or underwriter requests in
writing, to keep each such registration or qualification (or exemption
therefrom) effective during the Effectiveness Period and to do any and all
other acts or things necessary or advisable to enable the disposition in such
jurisdictions of the Registrable Securities covered by a Registration
Statement; provided, however, that the Company shall not be required to qualify
generally to do business in any jurisdiction where it is not then so qualified
or to take any action that would subject it to general service of process in
any such jurisdiction where it is not then so subject or subject the Company to
any material tax in any such jurisdiction where it is not then so subject.

(i)	Certificates. Cooperate with the Holder to facilitate the timely
preparation and delivery of certificates representing Registrable Securities to
be sold pursuant to a Registration Statement, which certificates shall be free,
to the extent permitted by applicable law and the Purchase Agreement, of all
restrictive legends, and to enable such Registrable Securities to be in such
denominations and registered in such names as any such managing underwriters or
Holders may request at least two (2) Business Days prior to any sale of
Registrable Securities.

(j)	Supplements and Amendments. Upon the occurrence of any event
contemplated by Section 3(c)(vi), as promptly as possible, prepare a supplement
or amendment, including a post-effective amendment, to the Registration
Statement or a supplement to the related Prospectus or any document
incorporated or deemed to be incorporated therein by reference, and file any
other required document so that, as thereafter delivered, neither the
Registration Statement nor such Prospectus will contain an untrue statement of
a material fact or omit to state a material fact required to be stated therein
or necessary to make the statements therein, in light of the circumstances
under which they were made, not misleading.

(k)	Listing. Cause all Registrable Securities relating to each Registration
Statement to be listed on Nasdaq and any other securities exchange, quotation
system, market or over-the-counter bulletin board, if any, on which similar
securities issued by the Company are then listed as and when required pursuant
to the Purchase Agreement.

(l)	Earnings Statement. Comply in all material respects with all applicable
rules and regulations of the Commission and make generally available to its
securityholders earning statements satisfying the provisions of Section 11(a)
of the Securities Act and Rule 158 not later than 45 days after the end of any
12-month period (or 90 days after the end of any 12- month period if such
period is a fiscal year), commencing on the first day of the first fiscal
quarter of the Company after the effective date of the Registration Statement,
which statement shall conform to the requirements of Rule 158.
<PAGE>
(m)	Information. The Company may require each selling Holder to furnish to
the Company information regarding such Holder and the distribution of such
Registrable Securities as is required by law to be disclosed in the
Registration Statement, and the Company may exclude from such registration the
Registrable Securities of any such Holder who unreasonably fails to furnish
such information within a reasonable time after receiving such request.

The Company shall hold in confidence and not make any disclosure of information
concerning a Holder provided to the Company unless (i) disclosure of such
information, in the opinion of counsel to the Company, is required by law, (ii)
the disclosure of such information is necessary to avoid or correct a
misstatement or omission in any Registration Statement, (iii) disclosure of
such information is required by court or administrative order or is necessary
to respond to inquiries of regulatory authorities (provided, however, that the
Holder shall be given notice of any such pending disclosure so that the Holder
may seek a protective order), or (iv) such information has been made generally
available to the public other than by disclosure in violation of this or any
other agreement. The Company agrees that it shall, upon learning that
disclosure of such information concerning a Holder is sought in or by a court
or governmental body of competent jurisdiction or through other means, give
prompt notice to such Holder prior to making such disclosure, and allow the
Holder, at its expense, to undertake appropriate action to prevent disclosure
of, or to obtain a protective order for, such information.

If the Registration Statement refers to any Holder by name or otherwise as the
holder of any securities of the Company, then such Holder shall have the right
to require (if such reference to such Holder by name or otherwise is not
required by the Securities Act or any similar Federal statute then in force)
the deletion of the reference to such Holder in any amendment or supplement to
the Registration Statement filed or prepared subsequent to the time that such
reference ceases to be required.

Each Holder covenants and agrees that (i) it will not sell any Registrable
Securities under the Registration Statement until it has received copies of the
Prospectus as then amended or supplemented as contemplated in Section 3(g) and
notice from the Company that such Registration Statement and any post-effective
amendments thereto have become effective as contemplated by Section 3(c) and
(ii) it and its officers, directors or Affiliates, if any, will comply with the
prospectus delivery requirements of the Securities Act as applicable to them in
connection with sales of Registrable Securities pursuant to the Registration
Statement.

Each Holder agrees by its acquisition of such Registrable Securities that, upon
receipt of a notice from the Company of the occurrence of any event of the kind
described in Section 3(c)(ii), 3(c)(iii), 3(c)(iv), 3(c)(v) or 3(c)(vi), such
Holder will forthwith discontinue disposition of such Registrable Securities
under the Registration Statement until such Holder's receipt of the copies of
the supplemented Prospectus and/or amended Registration Statement contemplated
by Section 3(j), or until it is advised in writing (the "Advice") by the
Company that the use of the applicable Prospectus may be resumed, and, in
either case, has received copies of any additional or supplemental filings that
are incorporated or deemed to be incorporated by reference in such Prospectus
or Registration Statement. Notwithstanding anything to the contrary, the
Company shall cause its transfer agent to deliver unlegended shares of Common
Stock to a transferee of a Holder in accordance with the terms of the
Securities Purchase Agreement in connection with any sale of Registrable
Securities with respect to which an Holder has entered into a contract for sale
prior to the Holder's receipt of a notice from the Company of the happening of
any event of the kind described in Section 3(c)(ii), 3(c)(iii), 3(c)(iv),
<PAGE>
3(c)(v) or 3(c)(vi) and for which the Holder has not yet settled.

(n)	Responses to the Commission. The Company agrees to respond fully and
completely to any and all comments on a Registration Statement received from
the Commission staff as promptly as possible but, for non-Underwritten
Offerings, in no event later than ten (10) Business Days of the receipt of such
comments, regardless of whether such comments are in oral or written form.

(o)	Confirmation of Effectiveness. Within two (2) Business Days after a
Registration Statement which covers applicable Registrable Securities is
ordered effective by the Commission, the Company shall deliver, and shall cause
legal counsel for the Company to deliver, to the transfer agent for such
Registrable Securities (with copies to the Holders whose Registrable Securities
are included in such Registration Statement) confirmation that such
Registration Statement has been declared effective by the Commission in the
form attached hereto as Exhibit B.

(p) Notwithstanding any other provision of this Section 3, the Company may
delay the filing or effectiveness of any Registration Statement or any
amendment or supplement thereto and suspend the right of the Holders to effect
sales of Registrable Securities thereunder for one or more periods (each a
"Suspension Period") of up to 60 calendar days in the aggregate per twelve (12)
month period in the event that such filing, effectiveness or sale would require
the Company to disclose any non-public information that the Company is not
otherwise required to disclose or to file any financial statements that the
Company is not otherwise required to file, provided however, that no Suspension
Period shall exceed 45 consecutive calendar days.

(q) Notwithstanding any other provision of this Section 3, the Holders shall
not be permitted to effect sales of the Registrable Securities under a
Registration Statement during a period in which the Company is engaged in the
process of registering under the Securities Act in an underwritten offering,
for as long as the underwriter reasonably considers is necessary.

	4.	Registration Expenses

All fees and expenses incident to the performance of or compliance with this
Agreement by the Company (other than Section 7(c) hereof which will be governed
by Section 7(c) of the Brown Simpson Agreement) shall be borne by the Company,
whether or not the Registration Statement is filed or becomes effective and
whether or not any Registrable Securities are sold pursuant to the Registration
Statement. The fees and expenses referred to in the foregoing sentence shall
include, without limitation, (i) all registration and filing fees (including,
without limitation, fees and expenses (A) with respect to filings required to
be made with Nasdaq and each other securities exchange or market on which
Registrable Securities are required hereunder to be listed and (B) in
compliance with state securities or Blue Sky laws (including, without
limitation, fees and disbursements of counsel for the Holders in connection
with Blue Sky qualifications as determined by a majority in interest of the
Holders), (ii) printing expenses (including, without limitation, expenses of
printing certificates for Registrable Securities and of printing prospectuses
if the printing of prospectuses is requested by the holders of a majority of
the Registrable Securities included in the Registration Statement), (iii)
messenger, telephone and delivery expenses, (iv) reasonable fees and
disbursements of counsel for the Company, (v) Securities Act liability
insurance, if the Company so desires such insurance, and (vi) fees and expenses
of all other Persons retained by the Company in connection with the
consummation of the transactions contemplated by this Agreement. In addition,
the Company shall be responsible for all of its internal expenses incurred in
<PAGE>
connection with the consummation of the transactions contemplated by this
Agreement (including, without limitation, all salaries and expenses of its
officers and employees performing legal or accounting duties), the expense of
any annual audit, and the fees and expenses incurred in connection with the
listing of the Registrable Securities on any securities exchange as required
hereunder. The Company shall not be required to pay selling concessions,
discounts or other compensation paid to brokers, underwriters or other agents
in connection with the sale of any Registrable Securities, whether or not
incurred in an Underwritten Offering, or fees and expenses incurred by a Holder
that are not specified in this Section.

5.	Indemnification

(a)	Indemnification by the Company. The Company shall, notwithstanding any
termination of this Agreement, indemnify and hold harmless each Holder, the
officers, directors, agents (including any underwriters retained by such Holder
in connection with the offer and sale of Registrable Securities), investment
advisors and employees of each of them, each Person who controls any such
Holder (within the meaning of Section 15 of the Securities Act or Section 20 of
the Exchange Act) and the officers, directors, agents and employees of each
such controlling Person, to the fullest extent permitted by applicable law,
from and against any and all joint or several losses, claims, damages,
liabilities, costs (including, without limitation, costs of preparation and
attorneys' fees) and expenses (collectively, together with actions, proceedings
or inquiries by any regulatory or self-regulatory organization, whether
commenced or threatened, "Losses"), as incurred, arising out of or relating to
(i) any untrue or alleged untrue statement of a material fact contained in the
Registration Statement, any Prospectus or any form of prospectus or in any
amendment or supplement thereto or in any preliminary Prospectus, or arising
out of or relating to any omission or alleged omission of a material fact
required to be stated therein or necessary to make the statements therein (in
the case of any Prospectus or form of prospectus or supplement thereto, in
light of the circumstances under which they were made) not misleading (in the
case of any Prospectus or form of prospectus or supplement thereto, in light of
the circumstances under which they were made), except to the extent, but only
to the extent, that such untrue statements or omissions are based upon and in
conformity with information regarding such Holder furnished in writing to the
Company by such Holder expressly for use therein, or (ii) any violation or
alleged violation by the Company of the Securities Act, the Exchange Act, any
other law, including, without limitation, any state securities law, or any rule
or regulation thereunder relating to the offer or sale of Registrable
Securities, provided, however, that the Company shall not be required to
indemnify any person with respect to a loss arising out of a sale of any
Registrable Securities during any period during which the Company has advised
the Holder to suspend sales pursuant to a registration statement. The Company
shall not, however, be liable for any Losses to any Holder with respect to any
untrue or alleged untrue statement of material fact or omission or alleged
omission of material fact if such statement or omission was made in a
preliminary Prospectus and such Holder did not receive a copy of the final
Prospectus (or any amendment or supplement thereto) at or prior to the
confirmation of the sale of the Registrable Securities in any case where such
delivery is required by the Securities Act and the untrue or alleged untrue
statement of material fact or omission or alleged omission of material fact
contained in such preliminary Prospectus was corrected in the final Prospectus
(or any amendment or supplement thereto), unless the failure to deliver such
final Prospectus (as amended or supplemented) was a result of noncompliance by
the Company with Section 3(g) of this Agreement. The Company shall notify the


<PAGE>
Holders promptly of the institution, threat or assertion of any Proceeding of
which the Company is aware in connection with the transactions contemplated by
this Agreement.

(b)	Indemnification by Holder. The Holder shall indemnify and hold harmless
the Company, the directors, officers, agents and employees, each Person who
controls the Company (within the meaning of Section 15 of the Securities Act
and Section 20 of the Exchange Act), and the directors, officers, agents or
employees of such controlling Persons, to the fullest extent permitted by
applicable law, from and against all Losses, as incurred, arising solely out of
or based solely upon (i) any untrue statement of a material fact contained in
the Registration Statement, any Prospectus, or any form of prospectus, or
arising solely out of or based solely upon any omission of a material fact
required to be stated therein or necessary to make the statements therein not
misleading to the extent, but only to the extent, that such untrue statement or
omission is contained in any information so furnished in writing by such Holder
to the Company specifically for inclusion in the Registration Statement or such
Prospectus and that such information was reasonably relied upon by the Company
for use in the Registration Statement, such Prospectus or such form of
prospectus or to the extent that such information relates to such Holder or
such Holder's proposed method of distribution of Registrable Securities and was
reviewed and expressly approved in writing by such Holder expressly for use in
the Registration Statement, such Prospectus or such form of prospectus or (ii)
any violation or alleged violation by the Holders of the Securities Act, the
Exchange Act, any other law, including, without limitation, any state
securities law, or any rule or regulation thereunder relating to the offer or
sale of Registrable Securities; provided, however, that the indemnity agreement
contained in this Section 5(b) shall not apply to amounts paid in settlement of
any Losses if such settlement is effected without the prior written consent of
such Holder. In no event shall the liability of any selling Holder hereunder be
greater in amount than the dollar amount of the net proceeds received by such
Holder upon the sale of the Registrable Securities giving rise to such
indemnification obligation.

(c)	Conduct of Indemnification Proceedings. If any Proceeding shall be
brought or asserted against any Person entitled to indemnity hereunder (an
"Indemnified Party"), such Indemnified Party promptly shall notify the Person
from whom indemnity is sought (the "Indemnifying Party") in writing, and the
Indemnifying Party shall assume the defense thereof, including the employment
of counsel reasonably satisfactory to the Indemnified Party and the payment of
all fees and expenses incurred in connection with defense thereof; provided,
however, that the failure of any Indemnified Party to give such notice shall
not relieve the Indemnifying Party of its obligations or liabilities pursuant
to this Agreement, except (and only) to the extent that it shall be finally
determined by a court of competent jurisdiction (which determination is not
subject to appeal or further review) that such failure shall have proximately
and materially adversely prejudiced the Indemnifying Party.

An Indemnified Party shall have the right to employ separate counsel in any
such Proceeding and to participate in the defense thereof, but the fees and
expenses of such counsel shall be at the expense of such Indemnified Party or
Parties unless: (1) the Indemnifying Party has agreed in writing to pay such
fees and expenses; or (2) the Indemnifying Party shall have failed promptly to
assume the defense of such Proceeding and to employ counsel reasonably
satisfactory to such Indemnified Party in any such Proceeding; or (3) the named
parties to any such Proceeding (including any impleaded parties) include both
such Indemnified Party and the Indemnifying Party, and such Indemnified Party
shall have been advised by counsel that a conflict of interest is likely to
exist if the same counsel were to represent such Indemnified Party and the
<PAGE>
Indemnifying Party (in which case, if such Indemnified Party notifies the
Indemnifying Party in writing that it elects to employ separate counsel at the
expense of the Indemnifying Party, the Indemnifying Party shall not have the
right to assume the defense thereof and such counsel shall be at the expense of
the Indemnifying Party). The Indemnifying Party shall not be liable for any
settlement of any such Proceeding effected without its written consent, which
consent shall not be unreasonably withheld. No Indemnifying Party shall,
without the prior written consent of the Indemnified Party, effect any
settlement of any pending Proceeding in respect of which any Indemnified Party
is a party, unless such settlement includes an unconditional release of such
Indemnified Party from all liability on claims that are the subject matter of
such Proceeding.

All fees and expenses of the Indemnified Party (including reasonable fees and
expenses to the extent incurred in connection with investigating or preparing
to defend such Proceeding in a manner not inconsistent with this Section) shall
be paid to the Indemnified Party, as incurred, within ten (10) Business Days of
written notice thereof to the Indemnifying Party (regardless of whether it is
ultimately determined that an Indemnified Party is not entitled to
indemnification hereunder; provided, that the Indemnifying Party may require
such Indemnified Party to undertake to reimburse all such fees and expenses to
the extent it is finally judicially determined that such Indemnified Party is
not entitled to indemnification hereunder).

(d)	Contribution. If a claim for indemnification under Section 5(a) or 5(b)
is unavailable to an Indemnified Party because of a failure or refusal of a
court of competent jurisdiction to enforce such indemnification in accordance
with its terms (by reason of public policy or otherwise), then each
Indemnifying Party, in lieu of indemnifying such Indemnified Party, shall
contribute to the amount paid or payable by such Indemnified Party as a result
of such Losses, in such proportion as is appropriate to reflect the relative
fault of the Indemnifying Party and Indemnified Party in connection with the
actions, statements or omissions that resulted in such Losses as well as any
other relevant equitable considerations. The relative fault of such
Indemnifying Party and Indemnified Party shall be determined by reference to,
among other things, whether any action in question, including any untrue or
alleged untrue statement of a material fact or omission or alleged omission of
a material fact, has been taken or made by, or relates to information supplied
by, such Indemnifying Party or Indemnified Party, and the parties' relative
intent, knowledge, access to information and opportunity to correct or prevent
such action, statement or omission. The amount paid or payable by a party as a
result of any Losses shall be deemed to include, subject to the limitations set
forth in Section 5(c), any reasonable attorneys' or other reasonable fees or
expenses incurred by such party in connection with any Proceeding to the extent
such party would have been indemnified for such fees or expenses if the
indemnification provided for in this Section was available to such party in
accordance with its terms. In no event shall any selling Holder be required to
contribute an amount under this Section 5(d) in excess of the net proceeds
received by such Holder upon sale of the Registrable Securities pursuant to the
Registration Statement giving rise to such contribution obligation.

The parties hereto agree that it would not be just and equitable if
contribution pursuant to this Section 5(d) were determined by pro rata
allocation or by any other method of allocation that does not take into account
the equitable considerations referred to in the immediately preceding
paragraph. No Person guilty of fraudulent misrepresentation (within the meaning
of Section 11(f) of the Securities Act) shall be entitled to contribution from
any Person who was not guilty of such fraudulent misrepresentation.

<PAGE>
The indemnity and contribution agreements contained in this Section are in
addition to any liability that the Indemnifying Parties may have to the
Indemnified Parties.

	6.	Rule 144

During the Effectiveness Period, as long as any Holder owns Registrable
Securities, the Company covenants to timely file (or obtain extensions in
respect thereof and file within the applicable grace period) all reports
required to be filed by the Company after the date hereof pursuant to Section
13(a) or l5(d) of the Exchange Act. During the Effectiveness Period, as long as
any Holder owns Registrable Securities, if the Company is not required to file
reports pursuant to Section 13(a) or l5(d) of the Exchange Act, it will prepare
and furnish to the Holders and make publicly available in accordance with Rule
144(c) promulgated under the Securities Act annual and quarterly financial
statements, together with a discussion and analysis of such financial
statements in form and substance substantially similar to those that would
otherwise be required to be included in reports required by Section 13(a) or
15(d) of the Exchange Act, as well as any other information required thereby,
in the time period that such filings would have been required to have been made
under the Exchange Act. The Company further covenants that it will use
commercially reasonable efforts to take such further action as any Holder may
reasonably request, all to the extent required from time to time to enable such
Person to sell Underlying Shares without registration under the Securities Act
within the limitation of the exemptions provided by Rule 144 promulgated under
the Securities Act, including requesting of its counsel to provide any legal
opinions referred to in the Purchase Agreement. Upon the request of any Holder,
the Company shall deliver to such Holder a written certification of a duly
authorized officer as to whether it has complied with such requirements of this
Section 6.

	7.	Miscellaneous

(a)	Remedies. In the event of a breach by the Company or by a Holder of any
of their obligations under this Agreement, each Holder or the Company, as the
case may be, in addition to being entitled to exercise all rights granted by
law and under this Agreement, including recovery of damages, will be entitled
to specific performance of its rights under this Agreement. The Company and
each Holder agree that monetary damages would not provide adequate compensation
for any losses incurred by reason of a breach by it of any of the provisions of
this Agreement and hereby further agrees that, in the event of any action for
specific performance in respect of such breach, it shall waive the defense that
a remedy at law would be adequate.

(b)	No Inconsistent Agreements. Neither the Company nor any of its
subsidiaries has, as of the date hereof, nor shall the Company or any of its
subsidiaries, on or after the date of this Agreement, enter into any agreement
with respect to its securities that is inconsistent with the rights granted to
the Holder in this Agreement or otherwise conflicts with or limits the
provisions hereof. Except as disclosed in Schedule 2.1(a) of the Purchase
Agreement, neither the Company nor any of its subsidiaries has previously
entered into any agreement granting any registration rights with respect to any
of its securities to any Person. This Agreement, together with the Purchase
Agreement and the MTI Registration Rights Agreement, contain the entire
understanding of the parties with respect to the subject matter hereof and
supersede all prior agreements and understandings, oral or written, with
respect to such matters.


<PAGE>
(c)	Piggy-Back Registrations. Except as provided herein if, at any time
when there is not an effective Registration Statement covering the Registrable
Securities, the Company shall determine to prepare and file with the Commission
a registration statement relating to an offering for its own account or the
account of others under the Securities Act of any of its equity securities,
other than on Form S-4 or Form S-8 (each as promulgated under the Securities
Act) or their then equivalents relating to equity securities to be issued
solely in connection with any acquisition of any entity or business or equity
securities issuable in connection with stock option or other employee benefit
plans (and other than a registration statement filed pursuant to Section 2(b)
of the Registration Rights Agreement between the Company and Brown Simpson
Capital Management, LLC (and/or its affiliated fund), the Company shall send to
each Holder of Registrable Securities written notice of such determination and,
if within ten (10) days after receipt of such notice, any such Holder shall so
request in writing, (which request shall specify the Registrable Securities
intended to be disposed of by the Purchasers), the Company will use reasonable
efforts to effect the registration under the Securities Act of all Registrable
Securities which the Company has been so requested to register by the Holder,
to the extent requisite to permit the disposition of the Registrable Securities
so to be registered, provided that if at any time after giving written notice
of its intention to register any securities and prior to the effective date of
the registration statement filed in connection with such registration, the
Company shall determine for any reason not to register or to delay registration
of such securities, the Company may, at its election, give written notice of
such determination to such Holder and, thereupon, (i) in the case of a
determination not to register, shall be relieved of its obligation to register
any Registrable Securities in connection with such registration (but not from
its obligation to pay expenses in accordance with Section 4 hereof), and (ii)
in the case of a determination to delay registering, shall be permitted to
delay registering any Registrable Securities being registered pursuant to this
Section 7(c) for the same period as the delay in registering such other
securities. The Company shall include in such registration statement all or any
part of such Registrable Securities such Holder requests to be registered;
provided, however, that the Company shall not be required to register any
Registrable Securities pursuant to this Section 7(c) that are eligible for sale
pursuant to Rule 144(k) of the Securities Act. In the case of an underwritten
public offering, if the managing underwriter(s) or underwriter(s) should
reasonably object to the inclusion of the Registrable Securities in such
registration statement, then if the Company after consultation with the
Underwriter's representative should reasonably determine that the inclusion of
such Registrable Securities would materially adversely affect the offering
contemplated in such registration statement, and based on such determination
recommends inclusion in such registration statement of fewer Registrable
Securities then proposed to be sold by the Holders, then (x) the number of
Registrable Securities of the Holder and other holders of piggy-back
registration rights included in such registration statement shall be reduced
pro rata among such Holders and other holders of piggy-back registration rights
(based upon the number of Registrable Securities requested to be included in
the registration) or, in the case of other holders of piggy-back registration
rights, in the manner provided for in that applicable agreement, or (y) none of
the Registrable Securities of the Holders shall be included in such
registration statement if the Company, after consultation with the
underwriter(s), recommends the inclusion of none of such Registrable
Securities; provided, however, that if securities are being offered for the
account of other persons or entities as well as the Company, such reduction
shall not represent a greater fraction of the number of Registrable Securities
intended to be offered by the Holders than the fraction of similar reductions
imposed on such other persons or entities (other than the Company).
Notwithstanding the foregoing, the Company shall not file any registration
<PAGE>
statement under the Securities Act (other than on Form S-4 or Form S-8)
relating to the offer and sale of any equity securities of the Company, or
offer or sell any equity securities of the Company in a transaction exempt from
registration pursuant to Regulation S under the Securities Act, until such time
as the Initial Registration Statement has been effective for a period of sixty
(60) Trading Days, which period shall be tolled if the effectiveness of the
Initial Registration Statement is suspended for any reason whatsoever.

(d)	Further Obligations of the Company. Whenever, under the preceding
sections of this Agreement, the Company is required hereunder to register
Registrable Securities pursuant to Section 7(c) above, it agrees that it shall
also do the following:

(1)	Unless and until the distribution of all Registrable Securities
requested to be registered under section 7(c) above is complete, diligently
prepare for filing with the Commission a registration statement and such
amendments and supplements to said registration statement and the prospectus
used in connection therewith as may be necessary to keep said registration
statement effective for a period of at least 120 days and to comply with the
provisions of the Securities Act with respect to the sale of securities covered
by said registration statement for the period necessary to complete the
proposed public offering;

(2)	Furnish to any selling Holder of Registrable Securities such copies of
each preliminary and final prospectus and such other documents as such Holder
may reasonably request to facilitate the public offering of its Registrable
Securities;

(3) Enter into any underwriting agreement with provisions reasonably required
by the proposed underwriter for the selling Holder of Registrable Securities,
if any, and reasonably acceptable to the Company; and

(4) Register or qualify the Registrable Securities covered by said registration
statement under the securities or "blue-sky" laws of such jurisdictions as the
selling Holder of Registrable Securities may reasonably request.

(e)	Amendments and Waivers. The provisions of this Agreement, including the
provisions of this sentence, may not be amended, modified or supplemented, and
waivers or consents to departures from the provisions hereof may not be given,
unless the same shall be in writing and signed by the Company and the Holders
of at least two-thirds of the then outstanding Registrable Securities;
provided, however, that for the purposes of this sentence, Registrable
Securities that are owned, directly or indirectly, by the Company, or an
Affiliate of the Company are not deemed outstanding. Notwithstanding the
foregoing, a waiver or consent to depart from the provisions hereof with
respect to a matter that relates exclusively to the rights of Holder and that
does not directly or indirectly affect the rights of other Holder may be given
by Holders of at least a majority of the Registrable Securities to which such
waiver or consent relates; provided, however, that the provisions of this
sentence may not be amended, modified, or supplemented except in accordance
with the provisions of the immediately preceding sentence.

(f)	Notices. Any notice or other communication required or permitted to be
given hereunder shall be in writing and shall be deemed to have been received
(a) upon hand delivery (receipt acknowledged) or delivery by telex (with
correct answer back received), telecopy or facsimile (with transmission
confirmation report) at the address or number designated below (if received by
5:00 p.m. eastern time where such notice is to be received), or the first
Business Day following such delivery (if received after 5:00 p.m. eastern time

hereafter, in the same manner, by such Person.

(g)	Successors and Assigns. This Agreement shall inure to the benefit of
and be binding upon the successors and permitted assigns of each of the parties
and shall inure to the benefit of the Holder. The Company may not assign its
rights or obligations hereunder without the prior written consent of the
Holder. The Holder may assign its rights hereunder in the manner and to the
Persons as permitted under the Purchase Agreement. In addition, the rights of
the Holder hereunder, including the right to have the Company register for
resale Registrable Securities in accordance with the terms of this Agreement,
shall be automatically assignable by the Holder if: (i) the Holder agrees in
writing with the transferee or assignee to assign such rights, and a copy of
such agreement is furnished to the Company within a reasonable time after such
assignment, (ii) the Company is, within a reasonable time after such transfer
or assignment, furnished with written notice of (a) the name and address of
such transferee or assignee, and (b) the securities with respect to which such
registration rights are being transferred or assigned, (iii) following such
transfer or assignment the further disposition of such securities by the
transferee or assignees is restricted under the Securities Act and applicable
state securities laws, (iv) at or before the time the Company receives the
written notice contemplated by clause (ii) of this Section, the transferee or
assignee agrees in writing with the Company to be bound by all of the
provisions of this Agreement, and (v) such transfer shall have been made in
accordance with the applicable requirements of the Purchase Agreement. The
rights to assignment shall apply to the Holders (and to subsequent) successors
and assigns.

(h)	Counterparts. This Agreement may be executed in any number of
counterparts, each of which when so executed shall be deemed to be an original
and all of which taken together shall constitute one and the same Agreement. In
the event that any signature is delivered by facsimile transmission, such
signature shall create a valid and binding obligation of the party executing

and effect as if such facsimile signature were the original thereof.

(i)	Governing Law. The corporate laws of the State of Delaware shall govern
all issues concerning the relative rights of the Company and the Purchaser as
its stockholders. All other questions concerning the construction, validity,
enforcement and interpretation of this Agreement shall be governed by and
construed in accordance with the laws of the State of New York, without regard
to principles of conflicts of law. Each party hereby irrevocably submits to the
non-exclusive jurisdiction of the federal courts sitting in the City of Albany,
County of Albany or if diversity jurisdiction cannot be obtained, then in the
state courts sitting in the city of Albany, county of Albany, for the
adjudication of any dispute hereunder or in connection herewith or with any
transaction contemplated hereby or discussed herein, and hereby irrevocably
waives, and agrees not to assert in any suit, action or proceeding, any claim
<PAGE>
that it is not personally subject to the jurisdiction of any such court, that
such suit, action or proceeding is improper. Each party hereby irrevocably
waives personal service of process and consent to process being served in any
such suit, action or proceeding by mailing a copy thereof to such party at the
address for such notices to it under this Agreement and agrees that such
service shall constitute good and sufficient service of process and notice
thereof. Nothing contained herein shall be deemed to limit in any way any right
to serve process in any manner permitted by law.

(j)	Cumulative Remedies. The remedies provided herein are cumulative and
not exclusive of any remedies provided by law.

(k)	Severability. If any term, provision, covenant or restriction of this
Agreement is held by a court of competent jurisdiction to be invalid, illegal,
void or unenforceable, the remainder of the terms, provisions, covenants and
restrictions set forth herein shall remain in full force and effect and shall
in no way be affected, impaired or invalidated, and the parties hereto shall
use their reasonable efforts to find and employ an alternative means to achieve
the same or substantially the same result as that contemplated by such term,
provision, covenant or restriction. It is hereby stipulated and declared to be
the intention of the parties that they would have executed the remaining terms,
provisions, covenants and restrictions without including any of such that may
be hereafter declared invalid, illegal, void or unenforceable.

(l)	Headings. The headings in this Agreement are for convenience of
reference only and shall not limit or otherwise affect the meaning hereof.

(m)	Shares Held by The Company and its Affiliates. Whenever the consent or
approval of Holders of a specified percentage of Registrable Securities is
required hereunder, Registrable Securities held by the Company or its
Affiliates (other than any Holder or transferees or successors or assigns
thereof if such Holder is deemed to be an Affiliate solely by reason of its
holdings of such Registrable Securities) shall not be counted in determining
whether such consent or approval was given by the Holders of such required
percentage.

(n)	Revision of SEC Position on Warrants. In the event the rules and
regulations of the Commission or the policies of the staff of the Commission
are modified and as a result thereof the Company determines in good faith that
it may be practicable and in the interests of the Company and the Holders to
register the exercise of the Warrants so that the Warrant Shares may be freely
resold without maintaining an effective registration statement under the
Securities Act for resales, the Company and the Holders agree to cooperate in
good faith to effect such amendments to this Agreement as may be appropriate to
provide that the Company may fulfill its obligations hereunder with respect to
the Warrants and the Warrant Shares by maintaining an effective registration
statement under the Securities Act covering the exercise of the Warrants rather
than the resale of the Warrant Shares.

                                       EXHIBIT A


                                  PLAN OF DISTRIBUTION


Our company is registering the shares of common stock on behalf of the selling
stockholders. All costs, expenses and fees in connection with the registration
of the shares offered by this prospectus will be borne by the Company, other
than brokerage commissions and similar selling expenses, if any, attributable
to the sale of shares which will be borne by the selling stockholders. Sales of
shares may be effected by selling stockholders from time to time in one or more
types of transactions (which may include block transactions) on the Nasdaq
National Market, in the over-the-counter market, in negotiated transactions,
through put or call options transactions relating to the shares, through short
sales of shares, or a combination of such methods of sale, at market prices
prevailing at the time of sale, or at negotiated prices. Such transactions may
or may not involve brokers or dealers. The selling stockholders have advised
our company that they have not entered into any agreements, understandings or
arrangements with any underwriters or broker-dealers regarding the sale of
their securities, nor is there an underwriter or coordinated broker acting in
connection with the proposed sale of shares by the selling stockholders.

The selling stockholders may enter into hedging transactions with
broker-dealers or other financial institutions. In connection with such
transactions, broker-dealers or other financial institutions may engage in
short sales of the shares or of securities convertible into or exchangeable for
the shares in the course of hedging positions they assume with selling
stockholders. The selling stockholders may also enter into options or other
transactions with broker-dealers or other financial institutions which require
the delivery to such broker-dealers or other financial institutions of shares
offered by this prospectus, which shares such broker-dealer or other financial
institution may resell pursuant to this prospectus (as amended or supplemented
to reflect such transaction).

The selling stockholders may make these transactions by selling shares directly
to purchasers or to or through broker-dealers, which may act as agents or
principals. Such broker- dealers may receive compensation in the form of
discounts, concessions or commissions from selling stockholders and/or the
purchasers of shares for whom such broker-dealers may act as agents or to whom

<PAGE>
they sell as principal, or both (which compensation as to a particular broker-
dealer might be in excess of customary commissions).

The selling stockholders and any broker-dealers that act in connection with the
sale of shares are "underwriters" within the meaning of Section 2(11) of the
Securities Act, and any commissions received by such broker-dealers or any
profit on the resale of the shares sold by them while acting as principals
might be deemed to be underwriting discounts or commissions under the
Securities Act. The selling stockholders may agree to indemnify any agent,
dealer or broker-dealer that participates in transactions involving sales of
the shares against certain liabilities, including liabilities arising under the
Securities Act.

Because selling stockholders are "underwriters" within the meaning of Section
2(11) of the Securities Act, the selling stockholders will be subject to the
prospectus delivery requirements of the Securities Act. Our company has
informed the selling stockholders that the anti-manipulative provisions of
Regulation M promulgated under the Exchange Act may apply to their sales in the
market.

Selling stockholders also may resell all or a portion of the shares in open
market transactions in reliance upon Rule 144 under the Securities Act,
provided they meet the criteria and conform to the requirements of Rule 144.

Upon our company being notified by a selling stockholder that any material
arrangement has been entered into with a broker-dealer for the sale of shares
through a block trade, special offering, exchange distribution or secondary
distribution or a purchase by a broker or dealer, a supplement to this
prospectus will be filed, if required, pursuant to Rule 424(b) under the
Securities Act, disclosing:

- -	the name of each such selling stockholder and of the participating broker-
dealer(s);

- -	the number of shares involved;

- -	the initial price at which such shares were sold;

- -	the commissions paid or discounts or concessions allowed to such
broker- dealer(s), where applicable;

- -	that such broker-dealer(s) did not conduct any investigation to verify
the information set out or incorporated by reference in this prospectus; and

- -	other facts material to the transactions.

In addition, upon our company being notified by a selling stockholder that a
donee or pledgee intends to sell more than 500 shares, a supplement to this
prospectus will be filed.

Attn.:

		Re:	SatCon Technology Corporation

Ladies and Gentlemen:

We are counsel to SatCon Technology Corporation, a Delaware corporation (the
"Company"), and have represented the Company in connection with that certain
Securities Purchase Agreement (the "Purchase Agreement") entered into by and
among the Company and Mechanical Technology Incorporated (the "Holder")
pursuant to which the Company issued to the Holder its shares of the Company's
common stock, par value $0.01 per share (the "Common Stock"), and Warrants (the
"the Warrants") to acquire shares of Common Stock. Pursuant to the Purchase
Agreement, the Company also has entered into a Registration Rights Agreement
with the Holder (the "Registration Rights Agreement") pursuant to which the
Company agreed, among other things, to register the Registrable Securities (as
defined in the Registration Rights Agreement), including the shares of Common
Stock and shares of Common stock issuable upon exercise of the Warrants, under
the Securities Act of 1933, as amended (the "1933 Act"). In connection with the
Company's obligations under the Registration Rights Agreement, on
_______________, 1999, the Company filed a Registration Statement on Form S-3
(File No. 333-_____________) (the "Registration Statement") with the Securities
and Exchange Commission (the "SEC") relating to the Registrable Securities
which names each of the Holders as a selling stockholder thereunder.

In connection with the foregoing, we advise you that a member of the SEC's
staff has advised us by telephone that the SEC has entered an order declaring
the Registration Statement effective under the 1933 Act at [ENTER TIME OF
EFFECTIVENESS] on [ENTER DATE OF EFFECTIVENESS] and we have no knowledge, after
telephonic inquiry of a member of the SEC's staff, that any stop order
suspending its effectiveness has been issued or that any proceedings for that
purpose are pending before, or threatened by, the SEC and the Registrable
Securities are available for resale under the 1933 Act pursuant to the
Registration Statement.

							Very truly yours,
                                                        [ISSUER'S COUNSEL]

THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED WITH THE SECURITIES
AND EXCHANGE COMMISSION IN RELIANCE UPON AN EXEMPTION FROM REGISTRATION UNDER
THE SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), AND, ACCORDINGLY,
MAY NOT BE OFFERED OR SOLD EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION

36,000 shares                                             Warrant No.  1

                       MECHANICAL TECHNOLOGY INCORPORATED
                            STOCK PURCHASE WARRANT

Registered Owner: SatCon Technology Corporation

This certifies that, for value received, Mechanical Technology Incorporated, a
New York corporation, the ("Company") grants the following rights to the
Registered Owner, or assigns, of this Warrant:

1. Issue. Upon tender (in accordance with Section 5 hereof) to the Company, the
Company, within three (3) Business Days of the date thereof, shall issue to the
Registered Owner, or assigns, up to the number of shares specified in Section 2
hereof of fully paid and nonassessable shares of Common Stock that the
Registered Owner, or assigns, is otherwise entitled to purchase.

2. Number of Shares. The total number of shares of Common Stock that the
Registered Owner, or assigns, of this Warrant is entitled to receive upon
exercise of this Warrant (the "Warrant Shares") is 36,000 shares, subject to
adjustment from time to time as to the number and kind of securities for which
this Warrant is exercisable, all as set forth in Section 6 hereof. The Company
shall at all times reserve and hold available out of its authorized and unissued
shares of Common Stock or other securities, as the case may be, sufficient
shares of Common Stock to satisfy all conversion and purchase rights represented
by outstanding convertible securities, options and warrants, including this
Warrant. The Company covenants and agrees that all shares of Common Stock or
other securities, as the case may be, that may be issued upon the exercise of
this Warrant shall, upon issuance, be duly and validly issued, fully paid and
nonassessable, free from all taxes, liens and charges with respect to the
purchase and the issuance of the shares, and shall not have any legend or
restrictions on resale, expect as required by Section 3.13 of the Purchase
Agreement.

3. Exercise Price. The per share exercise price of this Warrant, representing
the price per share at which the shares of stock issuable upon exercise of this
Warrant may be purchased, is $37.66, subject to adjustment from time to time
pursuant to the provisions of Section 6 hereof (the "Exercise Price").

4. Exercise Period. This Warrant may be exercised from the Closing Date (as
defined in the Purchase Agreement) up to and including October 13, 2003 (the
"Exercise Period"). If not exercised during this period, this Warrant and all
rights granted under this Warrant shall expire and lapse.




<PAGE>
5. Tender; Issuance of Certificates.

a. Subject to Section 15 hereof, this Warrant may be exercised, in whole or in
part, by (i) actual delivery of (a) the Exercise Price in cash or exchange of
in-the-money warrants, (b) a duly executed Warrant Exercise Form, a copy of
which is attached to this Warrant as Exhibit A, properly executed by the
Registered Owner, or assigns, of this Warrant, and (c) by surrender of this
Warrant. The Warrant Shares so purchased shall be deemed to be issued to the
Registered Owner as of the close of business on the date (the "Exercise Date")
on which the last of the following shall have occurred: (i) this Warrant shall
have been surrendered and (ii) the completed Warrant Exercise Form shall have
been delivered and payment shall have been made for such shares as set forth
above. The payment and Warrant Exercise Form must be delivered to the registered
office of the Company either in person or as set for in Section 12 hereof.

b. In lieu of physical delivery of the Warrant, provided the Company's transfer
agent is participating in the Depositary Trust Company's ("DTC") Fast automated
Securities Transfer ("FAST") program, upon request of the Registered Owner and
in compliance with the provisions hereof, the Company shall use its best efforts
to cause its transfer agent to electronically transmit the Warrant Shares to the
Registered Owner by crediting the account of the Registered Owner's Prime Broker
with DTC through its Deposit Withdrawal Agent Commission system. The time period
for delivery described herein shall apply to the electronic transmittals
described herein.

c. The Registered Owner may, at its option, also elect to pay some or all of the
Exercise Price payable upon an exercise of this Warrant by canceling a portion
of this Warrant exercisable for such number of Warrant Shares as is determined
by dividing (i) the total Exercise Price payable in respect of the number of
Warrant Shares being purchased upon such exercise by (ii) the excess of the Fair
Market Value per share of Common Stock as of the Exercise Date over the Exercise
Price per share. If the Registered Owner wishes to exercise this Warrant
pursuant to this method of payment with respect to the maximum number of Warrant
Shares purchasable pursuant to this method, then the number of Warrant Shares so
purchasable shall be equal to the total number of Warrant Shares, minus the
product obtained by multiplying (x) the total number of Warrant Shares by (y) a
fraction, the numerator of which shall be the Exercise Price per share and the
denominator which shall be the Fair Market Value per share of Common Stock as of
the Exercise Date. The Fair Market Value per share of Common Stock shall be
determined as follows:

(i.)	If the Common Stock is listed on a national securities exchange, the
Nasdaq National Market or another nationally recognized trading system as of the
Exercise Date, the Fair Market Value per share of Common Stock shall be deemed
to be the average of the high and low reported sale prices per share of Common
Stock thereon on the trading day immediately preceding the Exercise Date
(provided that if no such price is reported on such day, the Fair Market Value
per share of Common Stock shall be determined pursuant to clause (ii)).

(ii).	If the Common Stock is not listed on a national securities exchange, the
Nasdaq National Market or another nationally recognized trading system as of the
Exercise Date, the Fair Market Value per share of Common Stock shall be deemed
to be the amount most recently determined by the Board of Directors to represent
the fair market value per share of the Common Stock (including, without
limitation, a determination for purposes of granting Common Stock options or
issuing Common Stock under an employee benefit plan of the Company); and upon
request of the Registered Owner, the Board of Directors (or a representative
thereof) shall promptly notify the Registered Owner of the Fair Market Value per
share of Common Stock.
<PAGE>
Notwithstanding the foregoing, if the Board of Directors has not made such a
determination within the three-month period prior to the Exercise Date, then (A)
the Board of Directors shall make a determination of the Fair Market Value per
share of the Common Stock within 15 days of a request by the Registered Owner
that it do so, and (B) the exercise of this Warrant pursuant to this Section
6(c) shall be delayed until such determination is made.

d. Certificates for the Warrant Shares so purchased, representing the aggregate
number of shares specified in the Warrant Exercise Form, and any cash payments
due under Section 14 hereof shall be delivered to the Registered Owner within a
reasonable time, not exceeding three (3) Business Days, after this Warrant shall
have been so exercised. The certificates so delivered shall be in such
denominations as may be requested by the Registered Owner and shall be
registered in the name of the Registered Owner or such other name as shall be
designated by such Registered Owner. If this Warrant shall have been exercised
only in part, then, unless this Warrant has expired, the Company shall, at its
expense, at the time of delivery of such certificates, deliver to the Registered
Owner a new Warrant representing the number of shares with respect to which this
Warrant shall not then have been exercised.

6. Adjustment of Exercise Price.

a. Common Stock Dividends; Common Stock Splits; Reverse Common Stock Splits. If
the Company, at any time while this Warrant is outstanding, (a) shall pay a
stock dividend on its Common Stock, (b) subdivide outstanding shares of Common
Stock into a larger number of shares, (c) combine outstanding shares of Common
Stock into a smaller number of shares or (d) issue by reclassification of shares
of Common Stock any shares of capital stock of the Company, then (i) the
Exercise Price shall be multiplied by a fraction the numerator of which shall be
the number of shares of Common Stock (excluding treasury shares, if any)
outstanding before such event and the denominator of which shall be the number
of shares of Common Stock outstanding (excluding treasury shares, if any) after
such event and (ii) the number of Warrant Shares shall be multiplied by a
fraction, the numerator of which shall be the number of shares of Common Stock
(excluding treasury shares, if any) outstanding after such event and the
denominator of which shall be the number of shares of Common Stock (excluding
treasury shares, if any) outstanding before such event. Any adjustment made
pursuant to this paragraph (6)(a) shall become effective immediately after the
record date for the determination of shareholders entitled to receive such
dividend or distribution and shall become effective immediately after the
effective date in the case of a subdivision, combination or re-classification.

b. Rights; Options; Warrants or Other Securities. If the Company, at any time
while this Warrant is outstanding, shall fix a record date for the issuance of
rights, options, warrants or other securities to all of the holders of Common
Stock entitling them to subscribe for or purchase, convert to, exchange for or
otherwise acquire shares of Common Stock for no consideration or at a price per
share less than the Exercise Price, the Exercise Price shall be multiplied by a
fraction, the denominator of which shall be the number of shares of Common Stock
(excluding treasury shares, if any) outstanding on the date of issuance of such
rights, options, warrants or other securities plus the number of additional
shares of Common Stock offered for subscription, purchase, conversion, exchange
or acquisition and the numerator of which shall be the number of shares of
Common Stock (excluding treasury shares, if any) outstanding on the date of
issuance of such rights, options, warrants or other securities plus the number
of shares which the aggregate offering price of the total number of shares so
offered would purchase at the Exercise Price. Such adjustment shall be made
whenever such rights, options, warrants or other securities are issued, and
shall become effective immediately after the record date for the determination
<PAGE>
of shareholders entitled to receive such rights, options, warrants or other
securities.

c. Subscription Rights. If the Company, at any time while this Warrant is
outstanding, shall fix a record date for the distribution to all of the holders
of Common Stock evidence of its indebtedness or assets or rights, options,
warrants or other security entitling them to subscribe for or purchase, convert
to, exchange for or otherwise acquire any security (excluding those referred to
in paragraphs 6(a) and (b) above), then in each such case the Exercise Price at
which the Warrant shall thereafter be exercisable shall be determined by
multiplying the Exercise Price in effect immediately prior to the record date
fixed for determination of shareholders entitled to receive such distribution by
a fraction, the denominator of which shall be the Per Share Market Value of
Common Stock determined as of the record date mentioned above, and the numerator
of which shall be such Per Share Market Value of the Common Stock on such record
date less the then fair market value at such record date of the portion of such
assets or evidence of indebtedness so distributed applicable to one outstanding
share of Common Stock as determined by the Board of Directors in good faith;
provided, however, that in the event of a distribution exceeding ten percent
(10%) of the net assets of the Company, such fair market value shall be
determined in accordance with the Appraisal Procedure. Such adjustment shall be
made whenever any such distribution is made and shall become effective
immediately after the record date mentioned above.

d. Rounding. All calculations under this Section 6 shall be made to the nearest
cent or the nearest l/l00th of a share, as the case may be.

e. Notice of Adjustment. Whenever the Exercise Price is adjusted pursuant to
paragraphs 6(a), (b) or (c), the Company shall promptly deliver to the
Registered Owner a notice setting forth the Exercise Price after such adjustment
and setting forth a brief statement of the facts requiring such adjustment.

f. Redemption Events. The following are "five days. On and after the date of any
Redemption Event, the Registered Owner shall have the option to require the
Company to redeem (the "Redemption Right"), for a period of thirty (30) days
after the Registered Owner receives notice of Redemption Event, in cash within
10 days of the Redemption Event, the Registered Owner's shares of Common Stock
immediately theretofore acquirable and receivable upon the exercise of such
Registered Owner's Warrant at a price per share equal to the product of (i) the
amount by which, if any, the Average Price immediately preceding the latest of
the effective date, the date of the closing, date of occurrence or the date of
the announcement, as the case may be, of the Redemption Event triggering such
Redemption Right exceeds the Exercise Price and (ii) the number of shares of
Common Stock issuable upon exercise of the Warrant immediately prior to such
Redemption Event. After the occurrence of (A), the Registered Owner shall have
the right at his or its option, in lieu of the Redemption Right, to exercise the
Warrant for shares of stock and other securities, cash and property receivable
upon or deemed to be held by holders of Common Stock following such Redemption
Event; the Registered Owner shall be entitled upon such event to receive such
amount of securities, cash or property as if the Registered Owner had exercised
the Warrant of the shares of the Common Stock issuable upon exercise of the
Warrant immediately prior to such Redemption Event (without taking into account
any limitations or restrictions on the exercise of the Warrant). In the case of
a transaction specified in (A) in which holders of the Company's Common Stock
receive cash, the Registered Owner shall have the right at his or its option, in
lieu of the Redemption Right, to exercise the Warrant for such number of shares
of the surviving company equal to the amount of cash into which the Warrant is
exercisable divided by the fair market value of the shares of the surviving
company on the effective date of the merger. In the case of (A), the Company
<PAGE>
shall not effect any such Redemption Event unless, prior to the consummation
thereof, each Person (other than the Company) which may be required to deliver
any stock, securities, cash or property upon the exercise of the Warrant as
provided herein shall assume, by written instrument delivered and reasonably
satisfactory to, the Registered Owner, (a) the obligations of the Company under
the Warrant (and if the Company shall survive the consummation of such
transaction, such assumption shall be in addition to, and shall not release the
Company from, any continuing obligations of the Company under this Warrant), (b)
the obligations of the Company under the Purchase Agreement, the Warrant and the
Registration Rights Agreement, and (c) the obligation to deliver to the
Registered Owner such shares of stock, securities, cash or property as, in
accordance with the foregoing provisions of this Section 6(f), the Registered
Owner may be entitled to receive. Nothing in this Section 6(f) shall be deemed
to authorize the Company to enter into any transaction not otherwise permitted
by the Purchase Agreement. This provision shall similarly apply to successive
Redemption Events.

g. Notice of Certain Events.  If:

(i) the Company shall declare a dividend (or any other distribution) on its
Common Stock; or

(ii) the Company shall declare a special nonrecurring cash dividend on or a
redemption of its Common Stock; or

(iii) the Company shall authorize the granting to the holders of the Common
Stock rights or warrants to subscribe for or purchase any shares of capital
stock of any class or of any rights; or

(iv) the approval of any shareholders of the Company shall be required in
connection with any reclassification of the Common Stock of the Company, any
consolidation or merger to which the Company is a party, any sale or transfer of
all or substantially all of the assets of the Company, or any compulsory share
exchange whereby the Common Stock is converted into other securities, cash or
property; or

(v) the Company shall authorize the voluntary or involuntary dissolution,
liquidation or winding up of the affairs of the Company;

then the Company shall cause to be filed at each office or agency maintained for
the purpose of exercise of this Warrant, and shall cause to be delivered to the
Registered Owner, at least 10 Business Days prior to the applicable record or
effective date hereinafter specified, a notice (provided such notice shall not
include any material non-public information) stating (x) the date on which a
record is to be taken for the purpose of such dividend, distribution,
redemption, rights or warrants, or if a record is not to be taken, the date as
of which the holders of Common Stock of record to be entitled to such dividend,
distributions, redemption, rights or warrants are to be determined or (y) the
date on which such reclassification, consolidation, merger, sale, transfer or
share exchange is expected to become effective or close, and the date as of
which it is expected that holders of Common Stock of record shall be entitled to
exchange their shares of Common Stock for securities, cash or other property
deliverable upon such reclassification, consolidation, merger, sale, transfer or
share exchange; provided, however, that the failure to mail such notice or any
defect therein or in the mailing thereof shall not affect the validity of the
corporate action required to be specified in such notice.



<PAGE>
h. Adjustment of Number of Shares. Upon each adjustment of the Exercise Price as
a result of the calculations made in this Section 6, this Warrant shall
thereafter evidence the right to receive, at the adjusted Exercise Price, that
number of shares of Common Stock (calculated to the nearest one-hundredth)
obtained by dividing (i) the product of the aggregate number of shares covered
by this Warrant immediately prior to such adjustment and the Exercise Price in
effect immediately prior to such adjustment of the Exercise Price by (ii) the
Exercise Price in effect immediately after such adjustment of the Exercise
Price.

7. Officer's Certificate. Whenever the number of shares purchasable upon
exercise shall be adjusted as required by the provisions of Section 7, the
Company shall forthwith file in the custody of its Secretary or an Assistant
Secretary at its principal office and with its stock transfer agent, if any, an
officer's certificate showing the adjusted Exercise Price, number of shares or
other securities determined as herein provided, setting forth in reasonable
detail the facts requiring such adjustment and the manner of computing such
adjustment. Each such officer's certificate shall be signed by the chairman,
president or chief financial officer of the Company and by the secretary or any
assistant secretary of the Company. Each such officer's certificate shall be
made available at all reasonable times for inspection by any Registered Owner of
the Warrants and the Company shall, forthwith after each such adjustment,
deliver a copy of such certificate to the each of the Registered Owners.

8. Definitions. Capitalized terms used herein and not otherwise defined herein
shall have the meanings given to such terms in the Purchase Agreement. As used
in this Warrant, the following terms have the following meanings:

"Affiliate" means, with respect to any Person, any other Person that directly or
indirectly controls or is controlled by or under common control with such
Person. For the purposes of this definition, "control," when used with respect
to any Person, means the possession, direct or indirect, of the power to direct
or cause the direction of the management and policies of such Person, whether
through the ownership of voting securities, by contract or otherwise; and the
terms of "affiliated," "controlling" and "controlled" have meanings correlative
to the foregoing.

"Appraisal Procedure" shall have the following meaning. The independent
directors of the Company shall determine the fair market value. The Holders
shall have ten (10) Business Days to provide the Company with written notice of
its approval or disapproval of such determination. If the Holders do not respond

assist in the carrying out of all the provisions of this Warrant and in the
taking of all such action as may reasonably be requested by the holder of this
Warrant in order to protect the exercise privilege of the holder of this Warrant
<PAGE>

this Warrant. Without limiting the generality of the foregoing, the Company (i)
will not increase the par value of any shares of Common Stock receivable upon
the exercise of this Warrant above the Exercise Price then in effect, and (ii)
will take all such actions as may be necessary or appropriate in order that the
Company may validly and legally issue fully paid and nonassessable shares of
Common Stock upon the exercise of this Warrant.

the Company shall distribute "poison pill" rights pursuant to a "poison pill"
shareholder rights plan (the "Rights"), the Company shall, in lieu of making any
adjustment pursuant to Section 6 hereof, make proper provision so that each
Registered Owner who exercises a Warrant after the record date for such
distribution and prior to the expiration or redemption of the Rights shall be
entitled to receive upon such exercise, in addition to the shares of Common
Stock issuable upon such exercise, a number of Rights to be determined as
follows: (i) if such exercise occurs on or prior to the date for the
distribution to the holders of Rights of separate certificates evidencing such
Rights (the "Distribution Date"), the same number of Rights to which a holder of
a number of shares of Common Stock equal to the number of shares of Common Stock
issuable upon such exercise at the time of such exercise would be entitled in
accordance with the terms and provisions of and applicable to the Rights; and
(ii) if such exercise occurs after the Distribution Date, the same number of
Rights to which a holder of the number of shares into which the Warrant to
exercised was exercisable immediately prior to the Distribution Date would have
been entitled on the Distribution Date in accordance with the terms and
provisions of and applicable to the Rights, and in each case subject to the
terms and conditions of the Rights.

20. Successors and Assigns. This Warrant shall be binding upon and inure to the
benefit of the Registered Owners and its assigns, and shall be binding upon any
entity succeeding to the Company by merger or acquisition of all or
substantially all the assets of the Company. The Company may not assign this
Warrant or any rights or obligations hereunder without the prior written consent
of the Registered Owner. The Registered Owner may assign this Warrant without
the prior written consent of the Company.

21. Transfers. The Company shall maintain a register (the "Register") containing
the name and address of the Registered Owner of this Warrant, which Register can
be relied upon by the Company as conclusive evidence of the Registered Owner. If
the Registered Owner transfers or assigns this Warrant it shall promptly notify

transfer or assignation was made. Upon receipt of such notice the Company shall

                          SATCON TECHNOLOGY CORPORATION
                             STOCK PURCHASE WARRANT

Registered Owner: Mechanical Technology Incorporated

This certifies that, for value received, SatCon Technology Corporation, a
Delaware corporation, the ("Company") grants the following rights to the
Registered Owner, or assigns, of this Warrant:

1. Issue. Upon tender (in accordance with Section 5 hereof) to the Company, the
Company, within three (3) Business Days of the date thereof, shall issue to the
Registered Owner, or assigns, up to the number of shares specified in Section 2
hereof of fully paid and nonassessable shares of Common Stock that the
Registered Owner, or assigns, is otherwise entitled to purchase.

2. Number of Shares. The total number of shares of Common Stock that the
Registered Owner, or assigns, of this Warrant is entitled to receive upon
exercise of this Warrant (the "Warrant Shares") is 36,000 shares, subject to
adjustment from time to time as to the number and kind of securities for which
this Warrant is exercisable, all as set forth in Section 6 hereof. The Company
shall at all times reserve and hold available out of its authorized and
unissued shares of Common Stock or other securities, as the case may be,
sufficient shares of Common Stock to satisfy all conversion and purchase rights
represented by outstanding convertible securities, options and warrants,
including this Warrant. The Company covenants and agrees that all shares of
Common Stock or other securities, as the case may be, that may be issued upon
the exercise of this Warrant shall, upon issuance, be duly and validly issued,
fully paid and nonassessable, free from all taxes, liens and charges with
respect to the purchase and the issuance of the shares, and shall not have any
legend or restrictions on resale, expect as required by Section 3.13 of the
Purchase Agreement.

3. Exercise Price. The per share exercise price of this Warrant, representing
the price per share at which the shares of stock issuable upon exercise of this
Warrant may be purchased, is $8.80, subject to adjustment from time to time
pursuant to the provisions of Section 6 hereof (the "Exercise Price").

4. Exercise Period. This Warrant may be exercised from the Closing Date (as
defined in the Purchase Agreement) up to and including October 13, 2003 (the
"Exercise Period"). If not exercised during this period, this Warrant and all
rights granted under this Warrant shall expire and lapse.




<PAGE>
5. Tender; Issuance of Certificates.

a. Subject to Section 15 hereof, this Warrant may be exercised, in whole or in
part, by (i) actual delivery of (a) the Exercise Price in cash, (b) a duly
executed Warrant Exercise Form, a copy of which is attached to this Warrant as
Exhibit A, properly executed by the Registered Owner, or assigns, of this
Warrant, and (c) by surrender of this Warrant. The Warrant Shares so purchased
shall be deemed to be issued to the Registered Owner as of the close of
business on the date (the "Exercise Date") on which the last of the following
shall have occurred: (i) this Warrant shall have been surrendered and (ii) the
completed Warrant Exercise Form shall have been delivered and payment shall
have been made for such shares as set forth above. The payment and Warrant
Exercise Form must be delivered to the registered office of the Company either
in person or as set for in Section 11 hereof.

b. In lieu of physical delivery of the Warrant, provided the Company's transfer
agent is participating in the Depositary Trust Company's ("DTC") Fast Automated
Securities Transfer ("FAST") program, upon request of the Registered Owner and
in compliance with the provisions hereof, the Company shall use its best
efforts to cause its transfer agent to electronically transmit the Warrant
Shares to the Registered Owner by crediting the account of the Registered
Owner's Prime Broker with DTC through its Deposit Withdrawal Agent Commission
system. The time period for delivery described herein shall apply to the
electronic transmittals described herein.

c. Certificates for the Warrant Shares so purchased, representing the aggregate
number of shares specified in the Warrant Exercise Form, and any cash payments
due under Section 13 hereof shall be delivered to the Registered Owner within a
reasonable time, not exceeding three (3) Business Days, after this Warrant
shall have been so exercised. The certificates so delivered shall be in such
denominations as may be requested by the Registered Owner and shall be
registered in the name of the Registered Owner or such other name as shall be
designated by such Registered Owner. If this Warrant shall have been exercised
only in part, then, unless this Warrant has expired, the Company shall, at its
expense, at the time of delivery of such certificates, deliver to the
Registered Owner a new Warrant representing the number of shares with respect
to which this Warrant shall not then have been exercised.

6. Adjustment of Exercise Price.

a. Common Stock Dividends; Common Stock Splits; Reverse Common Stock Splits. If
the Company, at any time while this Warrant is outstanding, (a) shall pay a
stock dividend on its Common Stock, (b) subdivide outstanding shares of Common
Stock into a larger number of shares, (c) combine outstanding shares of Common
Stock into a smaller number of shares or (d) issue by reclassification of
shares of Common Stock any shares of capital stock of the Company, then (i) the
Exercise Price shall be multiplied by a fraction the numerator of which shall
be the number of shares of Common Stock (excluding treasury shares, if any)
outstanding before such event and the denominator of which shall be the number
of shares of Common Stock outstanding (excluding treasury shares, if any) after
such event and (ii) the number of Warrant Shares shall be multiplied by a
fraction, the numerator of which shall be the number of shares of Common Stock
(excluding treasury shares, if any) outstanding after such event and the
denominator of which shall be the number of shares of Common Stock (excluding
treasury shares, if any) outstanding before such event. Any adjustment made
pursuant to this paragraph (6)(a) shall become effective immediately after the
record date for the determination of shareholders entitled to receive such
dividend or distribution and shall become effective immediately after the
effective date in the case of a subdivision, combination or re-classification.
<PAGE>
b. Rights; Options; Warrants or Other Securities. If the Company, at any time
while this Warrant is outstanding, shall fix a record date for the issuance of
rights, options, warrants or other securities to all of the holders of Common
Stock entitling them to subscribe for or purchase, convert to, exchange for or
otherwise acquire shares of Common Stock for no consideration or at a price per
share less than the Exercise Price, the Exercise Price shall be multiplied by a
fraction, the denominator of which shall be the number of shares of Common
Stock (excluding treasury shares, if any) outstanding on the date of issuance
of such rights, options, warrants or other securities plus the number of
additional shares of Common Stock offered for subscription, purchase,
conversion, exchange or acquisition and the numerator of which shall be the
number of shares of Common Stock (excluding treasury shares, if any)
outstanding on the date of issuance of such rights, options, warrants or other
securities plus the number of shares which the aggregate offering price of the
total number of shares so offered would purchase at the Exercise Price. Such
adjustment shall be made whenever such rights, options, warrants or other
securities are issued, and shall become effective immediately after the record
date for the determination of shareholders entitled to receive such rights,
options, warrants or other securities.

c. Subscription Rights. If the Company, at any time while this Warrant is
outstanding, shall fix a record date for the distribution to all of the holders
of Common Stock evidence of its indebtedness or assets or rights, options,
warrants or other security entitling them to subscribe for or purchase, convert
to, exchange for or otherwise acquire any security (excluding those referred to
in paragraphs 6(a) and (b) above), then in each such case the Exercise Price at
which the Warrant shall thereafter be exercisable shall be determined by
multiplying the Exercise Price in effect immediately prior to the record date
fixed for determination of shareholders entitled to receive such distribution
by a fraction, the denominator of which shall be the Per Share Market Value of
Common Stock determined as of the record date mentioned above, and the
numerator of which shall be such Per Share Market Value of the Common Stock on
such record date less the then fair market value at such record date of the
portion of such assets or evidence of indebtedness so distributed applicable to
one outstanding share of Common Stock as determined by the Board of Directors
in good faith; provided, however, that in the event of a distribution exceeding
ten percent (10%) of the net assets of the Company, such fair market value
shall be determined in accordance with the Appraisal Procedure. Such adjustment
shall be made whenever any such distribution is made and shall become effective
immediately after the record date mentioned above.

d. Rounding. All calculations under this Section 6 shall be made to the nearest
cent or the nearest l/l00th of a share, as the case may be.

e. Notice of Adjustment. Whenever the Exercise Price is adjusted pursuant to
paragraphs 6(a), (b) or (c), the Company shall promptly deliver to the
Registered Owner a notice setting forth the Exercise Price after such
adjustment and setting forth a brief statement of the facts requiring such
adjustment.

f. Redemption Events. The following are "Redemption Events" under this Section
6(f): (A) any Change of Control or (B) any suspension from listing or delisting
of the Common Stock from the Nasdaq or any Subsequent Market on which the
Common Stock is listed for a period of five consecutive days. On and after the
date of any Redemption Event, the Registered Owner shall have the option to
require the Company to redeem (the "Redemption Right"), for a period of thirty
(30) days after the Registered Owner receives notice of Redemption Event, in
cash within 10 days of the Redemption Event, the Registered Owner's shares of
Common Stock immediately theretofore acquirable and receivable upon the
<PAGE>
exercise of such Registered Owner's Warrant at a price per share equal to the
product of (i) the amount by which, if any, the Average Price immediately
preceding the latest of the effective date, the date of the closing, date of
occurrence or the date of the announcement, as the case may be, of the
Redemption Event triggering such Redemption Right exceeds the Exercise Price
and (ii) the number of shares of Common Stock issuable upon exercise of the
Warrant immediately prior to such Redemption Event. After the occurrence of
(A), the Registered Owner shall have the right at his or its option, in lieu of
the Redemption Right, to exercise the Warrant for shares of stock and other
securities, cash and property receivable upon or deemed to be held by holders
of Common Stock following such Redemption Event; the Registered Owner shall be
entitled upon such event to receive such amount of securities, cash or property
as if the Registered Owner had exercised the Warrant of the shares of the
Common Stock issuable upon exercise of the Warrant immediately prior to such
Redemption Event (without taking into account any limitations or restrictions
on the exercise of the Warrant). In the case of a transaction specified in (A)
in which holders of the Company's Common Stock receive cash, the Registered
Owner shall have the right at his or its option, in lieu of the Redemption
Right, to exercise the Warrant for such number of shares of the surviving
company equal to the amount of cash into which the Warrant is exercisable
divided by the fair market value of the shares of the surviving company on the
effective date of the merger. In the case of (A), the Company shall not effect
any such Redemption Event unless, prior to the consummation thereof, each
Person (other than the Company) which may be required to deliver any stock,
securities, cash or property upon the exercise of the Warrant as provided
herein shall assume, by written instrument delivered and reasonably
satisfactory to, the Registered Owner, (a) the obligations of the Company under
the Warrant (and if the Company shall survive the consummation of such
transaction, such assumption shall be in addition to, and shall not release the
Company from, any continuing obligations of the Company under this Warrant),
(b) the obligations of the Company under the Purchase Agreement, the Warrant
and the Registration Rights Agreement, and (c) the obligation to deliver to the
Registered Owner such shares of stock, securities, cash or property as, in
accordance with the foregoing provisions of this Section 6(f), the Registered
Owner may be entitled to receive. Nothing in this Section 6(f) shall be deemed
to authorize the Company to enter into any transaction not otherwise permitted
by the Purchase Agreement. This provision shall similarly apply to successive
Redemption Events.

g. Notice of Certain Events.  If:

(i) the Company shall declare a dividend (or any other distribution) on its
Common Stock; or

(ii) the Company shall declare a special nonrecurring cash dividend on or a
redemption of its Common Stock; or

(iii) the Company shall authorize the granting to the holders of the Common
Stock rights or warrants to subscribe for or purchase any shares of capital
stock of any class or of any rights; or

(iv) the approval of any shareholders of the Company shall be required in
connection with any reclassification of the Common Stock of the Company, any
consolidation or merger to which the Company is a party, any sale or transfer
of all or substantially all of the assets of the Company, or any compulsory
share exchange whereby the Common Stock is converted into other securities,

good faith assist in the carrying out of all the provisions of this Warrant and
in the taking of all such action as may reasonably be requested by the holder
of this Warrant in order to protect the exercise privilege of the holder of

Registered Owner who exercises a Warrant after the record date for such
distribution and prior to the expiration or redemption of the Rights shall be
entitled to receive upon such exercise, in addition to the shares of Common
Stock issuable upon such exercise, a number of Rights to be determined as
follows: (i) if such exercise occurs on or prior to the date for the

Stock issuable upon such exercise at the time of such exercise would be
entitled in accordance with the terms and provisions of and applicable to the
Rights; and (ii) if such exercise occurs after the Distribution Date, the same
number of Rights to which a holder of the number of shares into which the
Warrant to exercised was exercisable immediately prior to the Distribution Date

and provisions of and applicable to the Rights, and in each case subject to the
terms and conditions of the Rights.

benefit of the Registered Owners and its assigns, and shall be binding upon any
entity succeeding to the Company by merger or acquisition of all or
substantially all the assets of the Company. The Company may not assign this
Warrant or any rights or obligations hereunder without the prior written
consent of the Registered Owner. The Registered Owner may assign this Warrant
without the prior written consent of the Company.
<PAGE>
21. Transfers. The Company shall maintain a register (the "Register")
containing the name and address of the Registered Owner of this Warrant, which
Register can be relied upon by the Company as conclusive evidence of the
Registered Owner. If the Registered Owner transfers or assigns this Warrant it

notice the Company shall immediately update the Register to incorporate the new

the principles of conflicts of law thereof. Each party hereby irrevocably
submits to the nonexclusive jurisdiction of the state and federal courts
sitting in the City of Albany, County of Albany, for the adjudication of any
dispute hereunder or in connection herewith or with any transaction
contemplated hereby or discussed herein, and hereby irrevocably waives, and

The Landlord hereby leases to and the Tenant hereby leases from the Landlord
the premises described herein according to the terms and conditions of this
lease.

3.2	The Landlord will be deemed to have delivered possession of the
premises to the Tenant on the date set forth in the Workletter (Exhibit B) upon
substantial completion of the work set forth in the Workletter. Substantial
completion means that the Tenant can use the premises for their intended
purposes without material interference to its ordinary business activities and
a certificate of occupancy has been granted. The premises will be completed 30
days after occupancy unless otherwise agreed by Tenant and Landlord not to be
unreasonably withheld.

3.3	In the event that space shall become available which is contiguous to
the said 20,700 SF occupied by Tenant, Landlord shall first offer this to
Tenant before actively attempting to lease at prevailing rates.

$26,306.25   Years 6-10
<PAGE>
Monthly rent will be paid in advance on or before the first day of each
calendar month of the term. If the lease commencement date is on a day other
than the first day of a calendar month, then monthly rent will be appropriately
prorated by Landlord based on the actual number of calendar days in such month.
Monthly rent will be paid to Landlord, without written notice or demand, and
without deduction or offset (other than deductions or offsets expressly
permitted herein), in lawful money of the United States of America at

the Landlord's invoice and supporting detail the Tenant's proportionate share

or assessments levied in lieu of, or in addition to, real property taxes above
those incurred by the Landlord during the initial year of the lease (the base
year: December 1, 1999 - November 30, 2000). The base year amount is determined
by multiplying the tax rate in effect during the base year times the assessment

superior lien, now or after the date placed, charged or enforced against the
land, the building, or all or any portion of the project (except to the extent

ARTICLE 21:  INDEMNIFICATION

21.1	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, 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, judgements, and expenses (including without limitation reasonable
attorneys' fees) incurred in connection with or arising from:

(a)	the use or occupancy or manner of use or occupancy of the premises by
Tenant or any person claiming under Tenant;

<PAGE>
(b)     any activity, work, or thing done or permitted by Tenant in or about
the premises, the building, or the project;
(c)	any breach by Tenant or its employees, agents, contractors, or invitees

21.2	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.


ARTICLE 22:  DAMAGE AND DESTRUCTION

22.1	If the premises or the building are damaged by fire or other insured
casualty, Landlord will give Tenant written notice of the time which will be
needed to repair such damage, as determined by Landlord in its reasonable
discretion, and the election (if any) which Landlord has made according to this
Article 22. Such notice will be given before the 10th day (the "notice date")
after the fire or other insured casualty.

22.2	If the premises or the building are damaged by fire or other insured
casualty to an extent which may be repaired within 30 days after the notice
date, as reasonably determined by Landlord, Landlord will promptly begin to
repair the damage after the notice date and will diligently pursue the
completion of such repair. In that event this lease will continue in full force
and effect except that monthly rent will be abated on a pro rata basis from the
date of the damage until the date of the completion of such repairs (the
"repair period") based on the proportion of the rentable area of the premises
Tenant is unable to use during the repair period.

22.3	If the premises or the building are damaged by fire or other insured
casualty to an extent that may not be repaired within 30 days after the notice
date, as reasonably determined by Landlord, then (1) Landlord may cancel this
lease as of the date of such damage by written notice given to Tenant on or
before the notice date or (2) Tenant may cancel this lease as of the date of
such damage by written notice given to Landlord within 30 days after the notice
date. If neither Landlord nor Tenant so elects to cancel this lease, Landlord
will diligently proceed to repair the building and premises and monthly rent
will be abated on a pro rata basis during the repair period based on the
proportion of the rentable area of the premises Tenant is unable to use during
the repair period.

22.4	Notwithstanding the provisions of Subparagraphs 22.1, 22.2, and 22.3
above, if the premises or the building are damaged by uninsured casualty, or if
the proceeds of insurance are insufficient to pay for the repair of any damage
to the premises or the building, Landlord will have the option to repair such
damage or cancel this lease as of the date of such casualty by written notice
to Tenant on or before the notice date.

22.5	If any such damage by fire or other casualty is the result of the
willful conduct or gross negligence of Tenant, its agents, contractors,
employees or invitees, there will be no abatement of monthly rent as otherwise
provided for in this Article 22. Tenant will have no rights to terminate this
lease on account of any damage to the premises, the building, or the project,
except as set forth in this lease.

<PAGE>
ARTICLE 23:  EMINENT DOMAIN

Landlord must notify Tenant of any actions, intentions or plans of any person
to take all or part of the premises by eminent domain within 10 days of
Landlord's knowledge of such action, intention or plan ("Eminent Domain
Notice").

If all or any of the premises may be taken by exercise of the power of eminent
domain (or conveyed by Landlord in lieu of such exercise), Tenant may within 60
days of such Eminent Domain Notice notify Landlord of its intention to
terminate this lease. If all the premises are to be taken by eminent domain,
Tenant must terminate the lease effective as of a date (the "termination date")
which is the earlier of the date upon which the condemning authority takes
possession of the premises or the date on which title to the premises is vested
in the condemning authority. If less than all of the premises are taken by
eminent domain and Tenant elects not to terminate the lease, the monthly rent
will be abated in the proportion of the rentable area of the premises so taken
to the rentable area of the premises immediately before such taking, and
tenant's share will be appropriately recalculated. If 25% or more of the
building or the project is so taken, Landlord may cancel this lease by written
notice to Tenant given as of 120 days after the Eminent Domain Notice Date. In
the event of any such taking, the entire award will be paid to Landlord and
Tenant will have no right or claim to any part of such award; however, Tenant
will have the right to assert a claim against the condemning authority in a
separate action, so long as Landlord's award is not otherwise reduced, for
Tenant's moving expenses and leasehold improvements owned by Tenant.


ARTICLE 24:  DEFAULT

24.1	Events of Default. The following events are referred to, collectively,
as "events of default" or, individually, as an "event of default":

(a)	Tenant defaults in the due and punctual payment of rent, and such
default continues for 10 days after written notice from Landlord; however,
Tenant will not be entitled to more than 2 written notices for monetary
defaults during any 12 month period, and if after such written notice any rent
is not paid when due, an event of default will be considered to have occurred
without further notice;
(b)	This lease or the premises or any part of the premises are taken upon
execution or by other process of law directed against Tenant, or are taken upon
or subject to any attachment by any creditor of Tenant or claimant against
Tenant, and said attachment is not discharged or disposed of within 30 days
after its levy;
(c)	Tenant files a petition in bankruptcy or insolvency or for
reorganization or arrangement under the bankruptcy laws of the United States or
under any insolvency act of any state, or admits the material allegations of
any such petition by answer or otherwise, or is dissolved or makes an
assignment for the benefit of creditors;
(d)	Involuntary proceedings under any such bankruptcy law or insolvency act
or for the dissolution of Tenant are instituted against Tenant, or a receiver
or trustee is appointed for all or substantially all of the property of Tenant,
and such proceeding is not dismissed or such receivership or trusteeship
vacated within 60 days after such institution or appointment;
(e)	Tenant breaches any of the other agreements, terms, covenants, or
conditions that this lease requires Tenant to perform, and such breach
continues for a period of 30 days after written notice from Landlord to Tenant
or, if such breach cannot be cured reasonably within such 30 day period, if
Tenant fails to diligently commence to cure such breach within 30 days after
<PAGE>
written notice from Landlord and to complete such cure within a reasonable time
thereafter.

24.2	Landlord's Remedies. If any one or more events of default set forth in
Section 24.1 occurs then Landlord has the right, at its election:

(a)	To give Tenant written notice of Landlord's intention to terminate this
lease on the earliest date permitted by law or on any later date specified in
such notice, in which case Tenant's right to possession of the premises will
cease and this lease will be terminated, except as to Tenant's liability;
(b)	Without further demand or notice, to reenter and take possession of the
premises or any part of the premises, repossess the same, expel Tenant and
those claiming through or under Tenant, and remove the effects of both or
either, using such force for such purposes as may be necessary without
prejudice to any remedies for arrears of monthly rent or other amounts payable
under this lease; or
(c)	Without further demand or notice to cure any event of default and to
charge Tenant for the cost of effecting such cure, including without limitation
reasonable attorneys' fees.

24.3	Waiver of Redemption. The Tenant waives any right of redemption arising
as a result of the Landlord's exercise of its remedies under this Article 24.

24.4	Notice of Landlord's Default. In the event of any default in the
obligation of the Landlord under this lease, Tenant will deliver to Landlord
written notice listing the reasons for Landlord's default and Landlord will
have 30 days following receipt of such notice to cure such default or, in the
event the default cannot reasonably be cured within a 30 day period, to
commence action and proceed diligently to cure such default. A copy of such
notice to Landlord will be sent to any holder of a mortgage or other
encumbrance on the building or project of which Tenant has been notified in
writing, any such holder will also have the same time periods to cure such
default. If any such default remains uncured Tenant has the right at it's
election to cure such default at Landlord's expense with prior written
notification given to Landlord.

24.5	Self Help. If either party defaults, the other party may, without being
obligated and without waiving the default, cure the default. The defaulting
party shall pay upon demand, all costs, expenses, and disbursements incurred by
the non-defaulting party to cure the default.


ARTICLE 25:  MISCELLANEOUS

25.1	Late Charges. A late charge of 5% shall be assessed to any payment of
rent or additional rent not made within 10 days of the due date and shall be
considered additional rent. Interest on amounts more than 10 days past due
shall accrue and be payable at the rate of 1% per month.

25.2	No Waiver. The waiver by Landlord of any agreement, condition, or
provision contained in this lease will not be deemed to be a waiver of any
subsequent breach of the same or any other agreement, condition, or provision
contained in this lease, nor will any custom or practice that may grow up
between the parties in the administration of the terms of this lease be
construed to waive or to lessen the right of Landlord to insist upon the
performance by Tenant in strict accordance with the terms of this lease. The
subsequent acceptance of rent by Landlord will not be deemed to be a waiver of
any preceding breach by Tenant or any agreement, condition, or provision of

<PAGE>
this lease, other than the failure of Tenant to pay the particular rent so
accepted, regardless of Landlord's knowledge of such preceding breach at the
time of acceptance of such rent.

25.3	Estoppel Certificates. At any time and from time to time but within 10
days after prior written request by either party, the other party will execute,
acknowledge, and deliver promptly upon request, a certificate certifying that
this lease is in full force and effect and, if modified, stating the date and
nature of each modification.

25.4	Holding Over. Tenant will have no right to remain in possession of all
or any part of the premises after the expiration of the term without the
express consent of Landlord. If Tenant remains in possession of all or any part
of the premises after the expiration of the term, without the express consent
of Landlord: (a) such tenancy will be deemed to be a periodic tenancy from
month-to-month only; (b) such tenancy will not constitute a renewal or
extension of this lease for any further term; and (c) such tenancy may be
terminated by Landlord upon the earlier of 30 days prior written notice or the
earliest date permitted by law. In such event, monthly rent will be increased
to an amount equal to 120% of the monthly rent payable during the last month of
the term, and any other sums due under this lease will be payable in the amount
and at the times specified in this lease. Such month-to-month tenancy will be
subject to every other term, condition, and covenant contained in this lease.

25.5	Notices. Any notice, request, demand, consent, approval, or other
communication required or permitted under this lease must be in writing and
will be deemed to have been given when personally delivered, sent by facsimile
with receipt acknowledged, deposited with any nationally recognized overnight
carrier that routinely issues receipts, or deposited in any depository
regularly maintained by the United States Postal Service, postage prepaid,
certified mail, return receipt requested, addressed to the party for whom it is
intended at its address set forth in this lease. Either Landlord or Tenant may
add additional addresses or change its address for purposes of receipt of any
such communication by giving 10 days prior written notice of such change to the
other party in the manner prescribed in this Section 25.5.

25.6	Severability. If any provision of this lease proves to be illegal,
invalid, or unenforceable, the remainder of this lease will not be affected by
such finding, and in lieu of each provision of this lease that is illegal,
invalid, or unenforceable a provision will be added as a part of this lease as
similar in terms to such illegal, invalid, or unenforceable provision as may be
possible and be legal, valid, and enforceable.

25.7	Written Amendment Required. No amendment, alteration, modification of,
or addition to the lease will be valid or binding unless expressed in writing
and signed by Landlord and Tenant. Tenant agrees to make any modifications of
the terms and provisions of this lease required or requested by any lending
institution providing financing for the building, or project, as the case may
be, provided that no such modifications will materially adversely affect
Tenant's rights and obligations under this lease.

25.8	Confidentiality. The terms of this lease are considered confidential
and the Tenant shall not disclose any of the terms of this lease to anyone
except that the Tenant shall make those disclosures in financial statements
which are customarily made or such other disclosures as the Tenant may be
required to make by perspective creditors of the Tenant.



<PAGE>
25.9 Broker's Warranty. The parties warrant that CB Richard Ellis/Robert Cohn
is the only broker they dealt with on this lease. Landlord is solely
responsible for paying the broker's commission as per the Tenant's Request for
Proposal.

25.10	Entire Agreement. This lease, the exhibits and addenda, if any, contain
the entire agreement between Landlord and Tenant. No promises or
representations, except as contained in this lease, have been made to Tenant
respecting the condition or the manner of operating the premises, the building,
or the project.


25.11	Binding Effect. The covenants, conditions, and agreements contained in
this lease will bind and inure to the benefit of Landlord and Tenant and their
respective heirs, distributees, executors, administrators, successors, and,
except as otherwise provided in this lease, their assigns.


Landlord and Tenant have executed this lease as of the day and year first above
written.

     This Registration Rights Agreement (this "Agreement") is entered into as of
November 1, 1999 by and among Plug Power Inc., a Delaware corporation (the
"Company"), and each of the parties executing a signature page hereto (each a
"Holder" and collectively the "Holders").

     WHEREAS, the Holders are the owners of the number of shares of the common
stock, par value $.01 per share, of the Company (the "Common Stock") set forth
opposite their respective names on Exhibit A attached hereto (collectively, the
                                   ---------

     NOW, THEREFORE, in consideration of the mutual promises and agreements set
forth herein, and other valuable consideration, the receipt and sufficiency of
which are hereby acknowledged, the parties hereto hereby agree as follows:

The parties hereby agree as follows:

     SECTION 1.     DEFINITIONS.
                    -----------

      ----------
(including, without limitation, a prospectus that discloses information

     "Registration Statement" means any registration statement of the Company
      ----------------------
that covers any of the Registrable Securities pursuant to the provisions of this
Agreement, and all amendments and supplements to any such registration
statement, including post-effective amendments, in each case including the

to be incorporated by reference in such registration statement.

     "Securities Act" means the Securities Act of 1933, as amended from time to
      --------------

     SECTION  2.    PIGGYBACK REGISTRATION.
                    ----------------------

          (a)  If at any time or times after the date hereof while any
Registrable Securities are outstanding the Company proposes to register under
the Securities Act any shares of Common Stock (other than (i) a registration on
Form S-8 or any successor form or in connection with any employee or director
welfare, benefit or compensation plan, (ii) a registration on Form S-4 or any
successor form or in connection with an exchange offer, (iii) a registration in
connection with a securities or rights offering exclusively to the Company's
securityholders, (iv) a registration in connection with an offering solely to
employees of the Company or its affiliates, (v) a registration relating to a
transaction pursuant to Rule 145 or any other similar rule of the Commission
under the Securities Act or (vi) a shelf registration), then the Company will
give written notice of such proposed registration to the Holders at least ten
(10) business days before the filing of any Registration Statement with respect
thereto.  If within five (5) business days after such notice is given, the
Company receives a written request from any Holder for the inclusion in such
Registration Statement of some or all of the Registrable Securities held by such
Holder (which request will specify the number of Registrable Securities intended
to be disposed of by such Holder and the intended method of distribution
thereof), the Company will (subject to the provisions of paragraphs (b) and (c)
of this Section 2) include such Registrable Securities in such Registration
Statement.  The Company may withdraw a Registration Statement filed under this
Section 2 at any time prior to the time it becomes effective, provided that the
Company will give prompt notice of such withdrawal to the Holders which
requested to be included in such Registration Statement. Each Holder shall have
the right to request inclusion of such Holder's Registrable Securities in up to
three Registration Statements pursuant to this Section 2(a).  The rights of the
Holders under this Section 2(a) will terminate on the date on which the third
Registration Statement to which such rights apply is declared effective by the
Commission.

                                       2






<PAGE>

          (b)  In connection with any registration under this Section 2
involving an underwriting (an "Underwritten Offering"), the Company will not be
required to include a Holder's Registrable Securities in such Underwritten
Offering unless such Holder accepts the terms of the underwriting as agreed upon
between the Company and the underwriters selected by the Company. If the
managing underwriter(s) of an Underwritten Offering advises the Company that the
number of securities to be sold in such Underwritten Offering, including by
Persons other than the Company (including the Holders) (collectively, the
"Selling Stockholders"), is greater than the number which can be offered without
adversely affecting such Underwritten Offering, including, without limitation,
the price range or probability of success of such Underwritten Offering, then
the Company will include in such Underwritten Offering in the following
priority: (i) first, all shares the Company proposes to sell and (ii) second,
that number of shares of Common Stock proposed to be sold by the Selling
Stockholders (including Registrable Securities proposed to be sold by the
Holders) which, in the opinion of such managing underwriter(s), can be sold
without adversely affecting such Underwritten Offering, including, without
limitation, the price range or probability of success of such Underwritten
Offering, which shares shall be allocated among the Selling Stockholders
(including the Holders requesting registration) on a pro rata basis according to
the relationship that the number of shares requested to be included by each
Selling Stockholder (including the Registrable Securities requested to be
included by each Holder) in such Underwritten Offering bears to the total number
of shares requested to be registered by all Selling Stockholders (including the
total number of Registrable Securities requested to be registered by all
Holders).

          (c)  Each Holder hereby agrees that such Holder may not participate in
any Underwritten Offering unless such Holder (a) agrees to sell such Holder's
Registrable Securities on the basis provided in the underwriting arrangements
applicable to such Underwritten Offering and (b) completes and executes all
questionnaires, powers of attorney, indemnities, underwriting agreements and
other documents reasonably required under the terms of the underwriting
arrangements for such Underwritten Offering.


     SECTION 3.     REGISTRATION PROCEDURES.
                    -----------------------

          (a)  The Company will notify each Holder whose Registrable Securities
are included in a Registration Statement of the effectiveness of such
Registration Statement and will furnish to each such Holder, without charge,
such number of conformed copies of such Registration Statement and any post-
effective amendment thereto and such number of copies of the Prospectus
(including each preliminary Prospectus) and any amendments or supplements
thereto, as such Holder may reasonably request in order to facilitate the sale
of such Holder's Registrable Securities.

          (b)  The Company will promptly notify each Holder requesting
registration of, and confirm in writing, any request by the Commission for
amendments or supplements to the Registration Statement or the Prospectus
related thereto or for additional information.  In addition, the Company will
promptly notify each such Holder of, and confirm in writing, the

                                       3



<PAGE>

filing of the Registration Statement, any Prospectus supplement related thereto
or any post-effective amendment to the Registration Statement and the
effectiveness of any post-effective amendment.

          (c)  The Company will use commercially reasonable efforts to register
or qualify the Registrable Securities covered by any Registration Statement
under such other securities or "blue sky" laws of such states of the United
States as any Holder requesting registration reasonably requests; provided,
however, that the Company will not be required (i) to qualify as a foreign
corporation to do business in any jurisdiction in which it is not then
qualified, (ii) to file any general consent to service of process, or (iii) to
subject itself to taxation in any jurisdiction where it would not otherwise be
subject to taxation.

          (d)  At any time when a Prospectus relating to the Registration
Statement is required to be delivered under the Securities Act, the Company will
promptly notify each Holder holding Registrable Securities covered by such
Registration Statement of the happening of any event as a result of which the
Prospectus included in the Registration Statement includes an untrue statement
of a material fact or omits to state any material fact required to be stated
therein or necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading.  In such event, the
Company will promptly prepare and file with the Commission and furnish to each
such Holder a reasonable number of copies of a supplement or amendment to such
Prospectus so that, as thereafter deliverable to the purchasers of Registrable
Securities, such Prospectus will not contain any untrue statement of a material
fact or omit to state a material fact required to be stated therein or necessary
to make the statements therein, in light of the circumstances under which they
were made, not misleading.


     SECTION 4.     REGISTRATION EXPENSES.  The Company will bear all expenses
                    ---------------------
incurred in connection with the registration of the Registrable Securities
pursuant to Section 2 of this Agreement; provided, however, that the Holders
                                         -----------------
will be responsible and will pay for (i) any brokerage or underwriting discounts
and commissions and taxes of any kind (including, without limitation, transfer
taxes) with respect to any disposition, sale or transfer of Registrable
Securities, (ii) any fees or expenses of any counsel, accountants or other
persons retained or employed by the Holders and (iii) out-of-pocket expenses of
the Holders and their agents, including, without limitation, any travel costs.


     SECTION 5.     INDEMNIFICATION AND CONTRIBUTION.
                    --------------------------------

     (a)  Indemnification by the Company.  The Company agrees to indemnify and
          ------------------------------
hold harmless, to the full extent permitted by law, each Holder, its officers,
directors, employees and agents and each Person, if any, which controls such
Holder within the meaning of either Section 15 of the Securities Act or Section
20 of the Exchange Act, (collectively, "Controlling Persons"), from and against
all losses, claims, damages, liabilities and expenses (including

                                       4


<PAGE>

without limitation any legal or other fees and expenses reasonably incurred by
any Holder or any such Controlling Person in connection with defending or
investigating any action or claim in respect thereof) (collectively, "Damages")
to which any of them may become subject under the Securities Act or otherwise,
insofar as such Damages arise out of or are based upon (i) any untrue or alleged
untrue statement of material fact contained in any Registration Statement
(including any related preliminary or final Prospectus) pursuant to which
Registrable Securities of such Holder were registered under the Securities Act,
or (ii) any omission or alleged omission to state therein a material fact
necessary to make the statements therein, in light of the circumstances under
which they were made, not misleading, except insofar as and to the extent that
such statement or omission arose out of or was based upon information regarding
such Holder or its plan of distribution which was furnished to the Company by
such Holder for use therein, provided, further that the Company will not be
liable to any person who participates as an underwriter in the offering or sale
of Registrable Securities or any Controlling Person of such underwriter, in any
such case to the extent that any such Damages arise out of or are based upon (A)
an untrue statement or alleged untrue statement or omission or alleged omission
made in such Registration Statement (including any related preliminary or final
Prospectus) in reliance upon and in conformity with information furnished to the
Company for use in connection with the Registration Statement or the Prospectus
contained therein by such underwriter or Controlling Person or (B) the failure
of such underwriter or Controlling Person to send or give a copy of the final
Prospectus furnished to it by the Company at or prior to the time such action is
required by the Securities Act to the person claiming an untrue statement or
alleged untrue statement or omission or alleged omission if such statement or
omission was corrected in such final prospectus. The obligations of the Company
under this Section 5(a) shall survive the completion of any offering of
Registrable Securities pursuant to a Registration Statement under this Agreement
or otherwise and shall survive the termination of this Agreement.

     (b)  Indemnification by the Holders.  Each Holder agrees to indemnify and
          ------------------------------
hold harmless, to the full extent permitted by law, the Company, its directors,
officers, employees and agents and each Controlling Person of the Company, from
and against any and all Damages to which any of them may become subject under
the Securities Act or otherwise to the extent such Damages arise out of or are
based upon any untrue statement or omission or alleged untrue statement or
omission based upon (i) any untrue statement or alleged untrue statement of
material fact contained in any Registration Statement (including any related
preliminary or final Prospectus), or any omission or alleged omission to state
therein a material fact required to be stated therein or necessary to make the
statements therein, in light of the circumstances under which they were made,
not misleading, if and to the extent that such statement or omission arose out
of or was based upon information regarding such Holder or its plan of
distribution which was furnished to the Company by such Holder for use therein,
or (ii) the failure by such Holder to deliver or cause to be delivered to any
purchaser of the shares covered by the Registration Statement the Prospectus
contained in the Registration Statement (as amended or supplemented, if
applicable) furnished by the Company to such Holder. Notwithstanding the
foregoing, (A) in no event will a Holder have any obligation under this Section
5(b) for amounts the Company pays in settlement of any such loss, claim, damage,

                                       5




<PAGE>

liability or action if such settlement is effected without the consent of the
Holder (which consent shall not be unreasonably withheld) and (B) the total
amount for which a Holder shall be liable under this Section 5(b) shall not in
any event exceed the aggregate proceeds received by such Holder from the sale of
the Holder's Registrable Securities in such registration. The obligations of the
Holders under this Section 5(b) shall survive the completion of any offering of
Registrable Securities pursuant to a Registration Statement under this Agreement
or otherwise and shall survive the termination of this Agreement.

     (c)  Contribution.  To the extent that the indemnification provided for in
          ------------
paragraph (a) or (b) of this Section 5 is held by a court of competent
jurisdiction to be unavailable to an indemnified party in respect of any
Damages, then each indemnifying party under such paragraph, in lieu of
indemnifying such indemnified party thereunder, will contribute to the amount
paid or payable by such indemnified party as a result of such Damages (i) in
such proportion as is appropriate to reflect the relative benefits received by
the Company on the one hand, and each Holder on the other, from the offering of
the Registrable Securities or (ii) if the allocation provided by clause (i)
above is not permitted by applicable law, in such proportion as is appropriate
to reflect not only the relative benefits referred to in clause (i) above but
also the relative fault of the Company, on the one hand, and the Holders, on the
other, in connection with the statements or omissions which resulted in such
Damages, as well as any other relevant equitable considerations.  The relative
fault of the Company on the one hand and of the Holders on the other hand will
be determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or the omission or alleged omission to state
a material fact relates to information supplied by the Company or by the Holders
and the parties' relative intent, knowledge, access to information and
opportunity to correct or prevent such statement or omission; provided, however,
                                                              -----------------
that in no event shall the obligation of any indemnifying party to contribute
under this Section 5(c) exceed the amount that such indemnifying party would
have been obligated to pay by way of indemnification if the indemnification
provided for under paragraph (a) or (b) of this Section 5 had been available
under the circumstances.

     If indemnification is available under paragraph (a) or (b) of this Section
5, the indemnifying parties will indemnify each indemnified party to the full
extent provided in such paragraphs without regard to the relative benefits to or
relative fault of said indemnifying party or indemnified party or any other
equitable consideration provided for in this Section 5(c).

     The Company and each Holder agrees that it would not be just or equitable
if contribution pursuant to this Section 5(c) were determined by pro rata
allocation or by any other method of allocation that does not take account of
the equitable considerations referred to herein.

     No indemnified party guilty of fraudulent misrepresentation (within the
meaning of Section 11(f) of the Securities Act) shall be entitled to
contribution from any indemnifying party who was not guilty of such fraudulent
misrepresentation.

                                       6

such longer period as may be required by the managing underwriter(s)) beginning
on, the date of pricing of each Offering, to the extent timely notified in
writing by the Company or the managing underwriter(s).

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

of distribution of the Registrable Securities as the Company may from time to
time reasonably request in writing in order to comply with the Securities Act
and the provisions of this Agreement, (b) to the extent required by the
Securities Act, deliver or cause delivery of the Prospectus contained in the
Registration Statement to any purchaser of such Holder's Registrable Securities
covered by the Registration Statement, (c) promptly notify the Company of any
sale of Registrable Securities by such Holder and (d) notify the Company as
promptly as practicable of any inaccuracy or change in information previously
furnished by the Holder to the Company or of the occurrence of any event, in
either case as a result of which any Prospectus contains or would contain an
untrue statement of a material fact regarding the Holder or the Holder's
intended method of distribution of the Registrable Securities or omits or would
omit to state any material fact regarding the Holder or the Holder's intended
method of distribution of the Registrable Securities required to be stated
therein or necessary to make the statements therein not misleading in light of
the circumstances then existing, and promptly furnish to the Company any
additional information required to correct and update any previously furnished
information or required so that the Prospectus will not contain, with respect to
the Holder or the Holder's intended method of distribution of the Registrable
Securities, an untrue statement of a material fact or omit to state a material
fact required to be stated therein or necessary to make the statements therein
not misleading in light of the circumstances then existing.


     SECTION 8.  MISCELLANEOUS.
                 -------------

     (a)  Amendments and Waivers.  The provisions of this Agreement, including
          ----------------------
this Section 8(a), may not be amended, modified or supplemented, and waivers or
consents to departures from the provisions hereof will not be effective, unless

	Re:	Plug Power Inc. - Lock-Up Agreement

Ladies and Gentlemen:

The undersigned understands that you, as representatives (the
"Representatives"), have entered into an Underwriting Agreement on behalf of the
several Underwriters named in Schedule I to such agreement (collectively, the
"Underwriters"), with Plug Power Inc., a newly- formed Delaware corporation (the
"Company") that will succeed by merger (the "Merger") immediately prior to the
offering described below to all the assets and liabilities of Plug Power,
L.L.C., a Delaware limited liability company (the "LLC"), providing for a public
offering of the Common Stock of the Company (the "Shares") pursuant to a
Registration Statement on Form S-1 filed with the Securities and Exchange
Commission (the "SEC").

In consideration of the agreement by the Underwriters to offer and sell the
Shares, and of other good and valuable consideration the receipt and sufficiency
of which is hereby acknowledged, the undersigned agrees that, during the period
beginning from the date of the final Prospectus covering the public offering of
the Shares and continuing to and including the date 180 days after the date of
such final Prospectus, the undersigned will not offer, sell, contract to sell,
pledge, grant any option to purchase, make any short sale or otherwise dispose
of any Membership Interests in the LLC or shares of Common Stock of the Company,
or any options or warrants to purchase any Membership Interests in the LLC or
shares of Common Stock of the Company, or any securities convertible into,
exchangeable for or that represent the right to receive Membership Interests in
the LLC or shares of Common Stock of the Company, whether now owned or
hereinafter acquired, owned directly by the undersigned (including holding as a
custodian) or with respect to which the undersigned has beneficial ownership
within the rules and regulations of the SEC (collectively the "MTI Shares").

The foregoing restriction is expressly agreed to preclude the undersigned from
engaging in any hedging or other transaction which is designed to or which
reasonably could be expected to lead to or result in a sale or disposition of
the MTI Shares even if such Shares would be disposed of by someone other than
the undersigned. Such prohibited hedging or other transactions would include
without limitation any short sale or any purchase, sale or grant of any right
(including without limitation any put or call option) with respect to any of the






<PAGE>
MTI Shares or with respect to any security that includes, relates to, or derives
any significant part of its value from such Shares.

The undersigned further represents and agrees that the undersigned has not taken
and will not take, directly or indirectly, any action which is designed to or
which has constituted or which might reasonably be expected to cause or result
in stabilization or manipulation of the price of any security of the Company to
facilitate the sale or resale of the Shares, or which has otherwise constituted
or will constitute any prohibited bid for or purchase of the Shares or any
related securities.

Notwithstanding the foregoing, the undersigned may (i) transfer the MTI Shares
as a bona fide gift or gifts, provided that the donee or donees thereof agree to
be bound in writing by the restrictions set forth herein, (ii) transfer the MTI
Shares to any trust for the direct or indirect benefit of the undersigned or the
immediate family of the undersigned, provided that the trustee of the trust
agrees to be bound in writing by the restrictions set forth herein, and provided
further that any such transfer shall not involve a disposition for value, (iii)
pledge the MTI Shares to KeyBank pursuant to that certain Stock Pledge
Agreement, dated as of November 2, 1999, by and among the undersigned and
KeyBank (a copy of which is attached hereto as Exhibit A), provided that KeyBank
executes the letter attached hereto as Exhibit B, agreeing to be bound by the
restrictions set forth herein with respect to the MTI Shares, or (iv) with the
prior written consent of Goldman, Sachs & Co. on behalf of the Underwriters. For
purposes of this Lock-Up Agreement, "immediate family" shall mean any
relationship by blood, marriage or adoption, not more remote than first cousin.
In addition, notwithstanding the foregoing, if the undersigned is a corporation,
the corporation may transfer the capital stock of the Company to any
wholly-owned subsidiary of such corporation; provided, however, that in any such
case, it shall be a condition to the transfer that the transferee execute an
agreement stating that the transferee is receiving and holding such capital
stock subject to the provisions of this Agreement and there shall be no further
transfer of such capital stock except in accordance with this Agreement, and
provided further that any such transfer shall not involve a disposition for
value. The undersigned now has, and, except as contemplated by clause (i), (ii),
(iii), or (iv) above, for the duration of this Lock- Up Agreement will have,
good and marketable title to the Undersigned's Membership Interests in the LLC
(prior to effectiveness of the Merger) and Shares (after effectiveness of the
Merger), free and clear of all liens, encumbrances, and claims whatsoever. The
undersigned also agrees and consents to the entry of stop transfer instructions
with the Company's transfer agent and registrar against the transfer of the MTI
Shares except in compliance with the foregoing restrictions.

The undersigned understands that the Company and the Underwriters are relying
upon this Lock-Up Agreement in proceeding toward consummation of the offering.
The undersigned further understands that this Lock-Up Agreement is irrevocable
and shall be binding upon the undersigned's heirs, legal representatives,
successors, and assigns.

					Very truly yours,

Re: Plug Power Inc. - Mechanical Technology Incorporated Lock-Up Agreement

Ladies and Gentlemen:

The undersigned understands that you, as representatives (the
"Representatives"), have entered into an Underwriting Agreement on behalf of the
several Underwriters named in Schedule I to such agreement (collectively, the
"Underwriters"), with Plug Power Inc., a Delaware corporation (the "Company"),
and Plug Power, LLC, providing for a public offering of the Common Stock of the
Company (the "Shares") pursuant to a Registration Statement on Form S-1 filed
with the Securities and Exchange Commission (the "SEC").

The undersigned also understands that in connection with such offering you have
received a Lock-up Agreement dated as of November 2, 1999, from Mechanical
Technology Incorporated ("MTI"), an executed copy of which is attached hereto as
Exhibit A (the "MTI Lock-Up Agreement"). The undersigned further understands
that the MTI Lock-Up Agreement permits MTI to pledge the MTI Shares (as defined
therein) to the undersigned, only upon the execution by the undersigned of this
agreement.

In consideration of the agreement by the Underwriters to offer and sell the
Shares and to permit the pledge of the MTI shares to the undersigned, and of
other good and valuable consideration the receipt and sufficiency of which is
hereby acknowledged, the undersigned hereby agrees, with respect to the MTI
Shares, to be bound by all of the restrictions applicable to MTI and the MTI
Shares under the MTI Lock-Up Agreement, to the same extent and on the same terms
and conditions as would have been applicable to MTI thereunder in the absence of
the pledge of MTI Shares to the undersigned. The undersigned understands that
the Company and the Underwriters are relying upon this agreement in proceeding
toward consummation of the offering. The undersigned further understands that
this agreement is irrevocable and shall be binding upon the undersigned's heirs,
legal representatives, successors, and assigns.

						Very truly yours,
