PART I


ITEM 1:  BUSINESS

During the last two and a half years, MTI has undergone significant 
change.  In May 1996, First Albany Companies, Inc. ("FAC") acquired a 
substantial interest in MTI and led a series of financial and strategic 
transactions that have significantly changed MTI's operations and fiscal 
well-being.  In July 1996, MTI received an infusion of capital through a 
private placement of its Common Stock.  In December 1996, MTI and FAC 
succeeded in restructuring a significant outstanding debt of the Company 
by swapping the debt for Common Stock. This allowed the Company to 
receive an unqualified opinion in 1996 from its Independent Auditors, 
Coopers & Lybrand L.L.P., for the first time since 1992. On June 27, 
1997, the Company transferred a portion of the Technology Division to 
Plug Power, L.L.C. ("Plug Power") to form a joint venture between the 
Company and Edison Development Corp. ("EDC"), a subsidiary of DTE 
Energy, Corp.  Plug Power has focused exclusively on the research and 
development of an economically viable Proton Exchange Membrane ("PEM") 
fuel cell.  On September 30, 1997, the Company sold all of the assets of 
its L.A.B. Division to Noonan Machine Company of Franklin Park, 
Illinois.  The proceeds from this sale were used to pay down outstanding 
debt and build working capital.  On March 31, 1998, the Company sold the 
remainder of its Technology Division to a subsidiary of Foster-Miller, 
Inc., a Waltham, Massachusetts-based technology company.  These 
divestitures have enabled the Company to continue to invest in fuel cell 
technology through Plug Power and to better focus on its profitable test 
and measurement business.  In June, 1998, the Company raised 
approximately $7.2 million in a rights offering and committed to invest 
approximately $5 million of the proceeds in Plug Power, now an industry 
leader in development of fuel cells in the United States.

Today, MTI is a very different Company, substantially streamlined in 
focus, but with many challenges remaining.  MTI is a manufacturer of 
advanced test and measurements 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 sensing instruments and computer-based 
balancing systems, and Ling Electronics, Inc. ("Ling"), a developer and 
manufacturer of vibration test systems and power conversion products.  
MTI is also a fifty percent owner of Plug Power, which hopes to be the 
first commercial manufacturer of PEM fuel cells for residential and 
other applications.  

Advanced Products has two general product families: non-contact sensing 
instrumentation and computer-based balancing systems.  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.  Some 
of these products bear the trademarks FOTONIC and ACCUMEASURE, which are 
recognized in the industry worldwide.  Advanced Products'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.

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 and Ling are 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 these 
business units.

Plug Power, the Company's fuel cell joint venture, is developing a 
proton exchange membrane fuel cell for residential and automotive 
applications.  In June 1998, Plug Power introduced the world's first 
fuel cell powered home.  In September 1998, Plug Power announced a 
preliminary agreement with GE Power Systems to market and distribute 
Plug Power's residential fuel cell units worldwide.  Plug Power 
continues to need substantial investment to continue its research and 
development of the fuel cell and is aggressively pursuing additional 
funding sources. 

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 968 Albany-Shaker Road, Latham, New York 12110 and 
its telephone number is (518) 785-2211.  


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 
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.  The Company's interest in Plug 
Power may be reduced in certain circumstances.  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 Joint Venture"; 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 Joint Venture in the 
Consolidated Statements of Cash Flows for additional information regarding 
the assets contributed by the Company to Plug Power.  

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 that contribution. 
The Company paid approximately $191 thousand for the options, which mature 
in April 1999 ($250 thousand) and May 1999 ($2 million).  If the Company 
does not exercise its options, they will lapse.

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.  Such contributions will 
increase the Company's total contributions to Plug Power (including 
contributions of cash, assets, research credits and a below market 
lease) to $11.75 million over the period commencing on June 27, 1997 and 
ending on March 31, 1999. 

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.  The Company has recorded its 
proportionate share of Plug Power's losses to the extent of its recorded 
investment in Plug Power (including the foregoing obligation to 
contribute an additional $4 million through March 31, 1999).  

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 $7,178 thousand before offering costs of 
approximately $186 thousand for net proceeds of approximately $6,992 
thousand.  The Company will use some or all of the proceeds of the 
offering for investment in and/or loans to Plug Power.  In addition, some 
proceeds may be used for acquisitions for the Company's core businesses, 
efforts to increase market share, working capital, general corporate 
purposes and other capital expenditures. 

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 and Measurement.  The Technology Division is reported as a 
discontinued operation as of December 26, 1997, and the consolidated 
financial statements have been restated to report separately the net 
assets and operating results of the business. Net assets of the 
discontinued operation were $8 thousand and $3,186 thousand at September 
30, 1998 and 1997, respectively and the loss on discontinued operations 
in 1998 included a loss from operations of $516 thousand and a loss on 
disposal of $1,769 thousand.  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.  See Note 15 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 $2,600 thousand 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 $2,012 thousand 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 
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. 

The Company's wholly owned subsidiary, UTE of Asbury Park, New Jersey, 
filed for voluntary bankruptcy under Chapter 11 of the Federal Bankruptcy 
Code in April 1994. During October 1994, UTE commenced an orderly 
liquidation and final court approval occurred during the third quarter of 
fiscal 1996. Accordingly, the Company no longer includes Defense/Aerospace 
amongst its reportable business segments and UTE has been classified as a 
"discontinued operation" in the Company's Financial Statements. (See Note 
15 to the accompanying Consolidated Financial Statements).

During November 1994, the Company sold all of the outstanding capital 
stock of its subsidiary, ProQuip Inc. ("ProQuip") of Santa Clara, CA for 
approximately $13.3 million.  The sale resulted in a gain of approximately 
$6.8 million in fiscal 1995 and $750 thousand, as a result of the release 
of escrow funds, in fiscal 1996. (See Note 16 to the accompanying 
Consolidated Financial Statements). 


Business Segments

The Company currently conducts business in one business segment: 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. 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.

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 Electronics, Inc., 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.  

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 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 
$2,071,000 for 1998 and $3,861,000 for 1997.  The backlog relates to 
contracts awarded by government agencies or commercial customers.  
Approximately $110 thousand of the orders included in the September 30, 
1998 backlog may not be filled during the Company's current fiscal year. 


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 123 
as of September 30, 1998, compared to 178 as of the beginning of the 
fiscal year.

was a site manager for Teleflex Control. From September 1992 to November 
1994, he was President and Chief Operating Officer of MTI's former 
subsidiary United Telecontrol Electronics, Inc.


ITEM 2:  PROPERTIES

The Company owns and leases property in New York and 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 are located on a 36 acre site in Latham, 
New York.  The site includes three separate buildings that contain a total of 
approximately 116,000 square feet.  In October 1998, the Company completed 
construction of a new manufacturing and office facility for Advanced Products 
and corporate headquarters.  The former Advanced Products facility has been 
renovated and is being rented to Plug Power, as part of the Company's capital 
contribution to Plug Power.  See "Significant Developments in the Business". 
The lease expires on September 30, 2008.  The third building is being rented 
to Plug Power and NYFM, Incorporated.  Both Plug Power's and NYFM 
Incorporated's leases expire on March 31, 1999.


Ling Electronics', Inc. leases approximately 85,000 square feet of office and 
manufacturing space in Anaheim, California.  The lease will expire in June of 
2003.

In addition to the above property, the Company and its subsidiaries lease 
several small offices for field engineering and/or marketing personnel at 
various locations in the United States and United Kingdom.


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 13 
to the accompanying Consolidated Financial Statements (which description 
is incorporated herein by reference).

On or about February 6, 1997, Ling Holdings Group, Inc. ("Holdings")

commenced an action against the Company and its former chief executive 
officer, R. Wayne Diesel, in the Superior Court, Orange County, 
California, entitled Ling Holdings Group, Inc. v. Mechanical Technology 
Inc. et al, No. 775074.  In that action, Holdings alleged nine causes of 
action against the Company for breach of contract and tort.  All of the 
claims related to a Stock Purchase Agreement between Holdings and the 
Company. In the action, Holdings sought specific performance of the Stock 
Purchase Agreement (i.e., the sale of two subsidiaries of the Company, 
Ling Electronics, Inc. and Ling Electronics Limited), as well as 
compensatory and punitive damages.  The Company asserted counterclaims.

In August 1998, all but five of Holdings' causes of action were dismissed 
with prejudice.  The remaining causes of action were dismissed with 
prejudice in an oral statement of decision by the court after a trial, 
which began on September 21 and concluded September 30, 1998.  The 
Company's counterclaims were dismissed, as well.  The judgment, based upon 
the court's September 30 statement of decision, was entered November 17, 
1998. Holdings will have 60 days from the mailing of notice of entry of 
the judgment to appeal. 


ITEM 4:  SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

There were no matters submitted to a vote of the registrant's security 
holders during the fourth quarter of fiscal 1998.

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


Results of Operations: 1998 in Comparison with 1997

The following three paragraphs summarize significant organizational 
changes, which impact the comparison of 1998 and 1997 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 
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.  The Company's interest 
in Plug Power may be reduced in certain circumstances.  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 Joint Venture"; 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 Joint 
Venture in the Consolidated Statements of Cash Flows for additional 
information regarding the assets contributed by the Company to Plug Power.

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 
and Measurement.  The Technology Division is reported as a discontinued 
operation as of December 26, 1997, and the consolidated financial 
statements have been restated to report separately the net assets and 
operating results of the business. Net assets of the discontinued 
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 $2,600 thousand 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 $2,012 thousand 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 general/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 24% 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 of the Plug Power joint 
venture compared to a $300 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. 


Results of Operations: 1997 in Comparison with 1996     

The following three paragraphs summarize significant organizational 
changes, which impact the comparison of 1997 and 1996 results of 
operations.

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 $2,600 thousand 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 $2,012 thousand 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.

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 
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.  The Company's interest 
in Plug Power may be reduced in certain circumstances. 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 Joint Venture"; 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 Joint 
Venture in the Consolidated Statements of Cash Flows for additional 
information regarding the assets contributed by the Company to Plug Power.

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 certain Claim Participation Agreement dated 
December 21, 1993 and amended December 14, 1994, among United Telecontrol 
Electronics, Inc. ("UTE"), the Company and First Commercial Credit 
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.  (See "Liquidity and Capital Resources", 
below.) 

The following is management's discussion and analysis of certain 
significant factors, which have affected the Company's results of 
operations for 1997 compared to 1996.  This discussion relates only to the 
Company's continuing operations. 

Sales for fiscal 1997 totaled $24.1 million compared to $22.8 million for 
the prior year, an increase of 5.9% in fiscal 1997 compared to fiscal 
1996.  L.A.B and Advanced Products reported sales increases of 7.8% and 
19.4%, respectively and Ling reported a sales decrease of 0.2%.

Selling, general and administrative expenses for fiscal 1997 were 29.1% of 
sales, as compared to 31.1% in 1996. Product development and research 
costs during fiscal 1997 were 4.2% of sales, compared to 3.0% for 1996. 
Lower levels of general/administrative expenses for fiscal 1997 resulted 
primarily from cost reduction efforts during fiscal 1997 as well as 
certain expenses having been incurred during 1996 in connection with the 
now-discontinued efforts to sell Ling. 

Company 1997 operating income totaled $1.6 million compared to $1.1 
million for fiscal 1996, or an increase of $500 thousand. The increase 
in operating income is primarily due to continuing growth of revenues.  
Increased operating income was achieved in spite of higher product 
development costs. All divisions reported improvements, however, Ling 
continues to experience an operating loss.

In addition to the matters noted above, during the fourth quarter of 
fiscal 1997, the Company recorded a $2.0 million gain on the sale of the 
L.A.B. Division and a $330 thousand loss from the recognition of the 
Company's proportionate share of the loss of the Plug Power joint venture. 
Sales for the L.A.B. Division were $3.3 million in 1997 and $3.1 million 
in 1996.  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. Fiscal 1996 results included a $750 thousand gain from the 
sale of its former subsidiary ProQuip, as a result of the removal of 
contingencies.

Results during fiscal 1997 were further enhanced by lower interest 
expense, principally resulting from reduced indebtedness. Moreover, the 
Company has benefited from reduced income tax expense due to 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, 1998, the Company's order backlog was $2.1 million, a 
decrease of $1.8 million from the prior year-end.  This reduction reflects 
a decline due to orders expected in the fourth quarter of 1998 being 
shifted to the next fiscal year.
 
Inventories increased by $362 thousand in 1998 to support increased sales 
levels at Advanced Products.  Additionally, accounts receivable increased 
by $477 thousand in 1998 due to the timing of sales at the end of the 
fiscal year. 

Cash flow from continuing operations was $513 thousand in 1998 compared 
with $1,089 thousand in 1997 and ($49) thousand in 1996.  Cash flow from 
operating activities was impacted in 1998 and 1997 by positive operating 
income and fluctuations in working capital components.  

Working capital was $5.8 million at September 30, 1998, a $1.9 million 
decrease from $7.7 million at fiscal year-end 1997.  Capital used during 
fiscal 1998 was principally to fund short term operating cash flow 
requirements and pay construction costs.   

Capital expenditures were $3,166 thousand for 1998, $377 thousand for 1997 
and $170 thousand for 1996.  The increased capital expenditures in 1998 
were in accordance with the higher level of planned expenditures and the 
construction of a new facility for Advanced Products and corporate 
headquarters and renovations to an existing building leased to Plug Power. 
Capital expenditures in 1999 are expected to be about $4.4 million, which 
consists of additional expenditures associated with the construction of 
the new facility, computer software and hardware costs and manufacturing 
equipment.  The Company expects to finance these expenditures with cash 
from operations and existing credit facilities.  As of September 30, 1998, 
the Company was committed to construction costs of approximately $2,856 
thousand. 

Cash and cash equivalents were $5,567 thousand at September 30, 1998 
compared to $1,421 thousand at September 30, 1997, this increase is 
attributable to $6,992 thousand of net cash proceeds from the sale of 
common shares to existing shareholders through a rights offering, which 
closed on September 30, 1998 net of payments associated with the Company's 
construction project.

At September 30, 1998 and 1997, 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 reduction in net assets of discontinued operations of $3,178 thousand 
includes the transfer of $878 thousand of assets to continuing operations 
(principally land, building and management information systems) as well as 
the accrual for the loss on disposal of the Technology Division.  Such 
accrual included a provision for estimated operating results prior to 
disposal and an estimate of the loss on disposal and winddown of the 
Technology Division, which totaled $1,769 thousand.  The sale of the 
Technology Division was completed as of March 31, 1998.

On July 31, 1998, Plug Power asked the Company to commit to contribute $5 
million (in cash, other assets and research credits) to Plug Power to fund 
continuing operations for the period August 1, 1998 through March 31, 
1999. The Company has committed to the $5 million contribution request, 
which will be funded by the proceeds from the rights offering.  On August 
5, 1998, EDC and the Company each made short-term loans of $500 thousand 
to Plug Power, which were subsequently contributed to capital on September 
23, 1998.  On September 23, 1998, the Company also contributed $500 
thousand of accounts receivable from Plug Power to equity.  A liability 
for $4 million was recorded as of September 30, 1998 to reflect the 
Company's additional obligation to fund Plug Power during 1999.  In 
addition, Plug Power will continue to need substantial investment for the 
foreseeable future.  Plug Power continues to pursue strategic partners and 
additional sources of capital. Plug Power is currently negotiating with 
several strategic partners and has signed a preliminary Memorandum of 
Understanding with General Electric Power Systems.  There is no assurance, 
however, that Plug Power will successfully conclude any transactions with 
strategic partners or find other sources of capital.  If other sources of 
funding cannot be found, the Company will be faced with contributing 
and/or lending additional capital to Plug Power or dilution of its 
interest in Plug Power.  If EDC and the Company stop funding Plug Power 
and no additional sources of capital are found, Plug Power will not be 
able to continue as a going concern.

During fiscal 1996, First Albany Companies, Inc. ("FAC") had 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 
the Note Payable. FCCC was in default of its Term Loan to UCIC. FAC, as 
the owner of the rights to the Term Loan, filed suit seeking payment and 
obtained a summary judgment. 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. On December 27, 1996, the 
Company and FAC entered into an agreement under which the Company issued 
to FAC 1.0 million shares of Common Stock in full satisfaction of the Note 
Payable of $3 million and accrued interest of $1.2 million. Accordingly, 
the Company realized a gain on the extinguishment of debt totaling $2.5 
million, net of approximately $100 thousand of transaction related 
expenses and net of taxes of $106 thousand. 

The Company benefited in fiscal 1997 from the sale of the L.A.B. Division 
on September 30, 1997, with cash proceeds of $2.6 million and two notes 
receivable for a total of $650 thousand.  The cash proceeds were used to 
pay off the remaining balance on the Company's term loan to Chase 
Manhattan Bank and to provide for general working capital needs. 

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


Debt

The Industrial Development Agency for the Town of Colonie has agreed to 
issue $6 million in Industrial Development Revenue Bonds ("IDR") on behalf 
of the Company to assist in the construction of a new building for 

Advanced Products and the Company's corporate staff and renovation of
existing buildings leased to Plug Power.  The construction project is due 
to be completed as of April 1999.  First Albany Companies, Inc. ("FAC"), 
which owns 34% of the Company's stock, will underwrite the sale of the IDR 
Bonds.  Proceeds of the IDR Bonds will be deposited with a trustee for the 
bondholders.  The Company may draw the bond proceeds to cover qualified 
project costs.  The bond closing is expected to be completed on or about 
December 17, 1998.  FAC will receive no fees for underwriting the IDR 
Bonds but will be reimbursed for its out of pocket costs.


Year 2000

General

Mechanical Technology Incorporated's company-wide Year 2000 plan is 
proceeding on schedule.  The plan is addressing 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

At September 30, 1998, all internal systems have been identified, 
inventoried, prioritized and assessed for Year 2000 compliance. Systems 
found to be totally non-compliant were replaced, the remaining systems 
were found to be in compliance.  Plans are being developed to ensure 
that staff are available to oversee restarting certain machines and 
manually adjusting their dates.

Software Evaluation

At September 30, 1998, all software material to the Company has been 
identified, evaluated, and placed into one of three categories: (1) 
Found to be in full compliance and certified as such by vendors,  (2) 
Identified as requiring update  or (3) Identified as requiring 
replacement with compliant software.  Those in the latter category have 
been included in the current budget.

Third-Party Suppliers

This phase of the Year 2000 Plan will be completed by the end of the 2nd 
Quarter of fiscal 1999.  These third-party suppliers are in the process 
of implementing their own plans with an expected completion date of 
1999.  If any provider is not successfully compliant, the Company will 
evaluate selecting alternative providers at that time.

Facility Systems

The facility systems review is complete.  All systems are believed to be 

Year 2000 compliant including telephone, fire alarm, security, elevator
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 be non-compliant, compliant if modifications 
are made, 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).  Those products identified as non-compliant are products in 
the field that are not Year 2000 compliant, cannot be modified and must 
be replaced.  Products which can be modified will have upgrades 
available for sale during fiscal 1999.

Contingency Plans

This phase is currently being developed.  Contingency plans should be in 
place by the end of the 2nd Quarter of fiscal 1999.    

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 is 
approximately $120 thousand, which includes 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, 
1998 was $34 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 the implementation and

                    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, 1998 and 1997, and the results of their operations and their 
cash flows for each of the three years in the period ended September 30, 
1998, 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.

               MECHANICAL TECHNOLOGY INCORPORATED AND SUBSIDIARIES
                   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 50% interest in a joint 
venture.  The consolidated financial statements include the Company's 
investments in the joint venture (including obligations to invest), plus 
its share of undistributed earnings/losses.  The investment is included in 
the financial line "Investment in Joint Venture".

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, 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 
ranging from 3 to 40 years.  Significant additions or improvements 
extending assets' useful lives are capitalized; normal maintenance and 
repair costs are expensed as incurred.  The cost of fully depreciated 
assets remaining in use are included in the respective asset and 
accumulated depreciation accounts.  When items are sold or retired, 
related gains or losses are included in net income.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(1)  Accounting Policies (continued)

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.

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.

(1) Accounting Policies (continued)

Advertising

The costs of advertising are expensed as incurred.  Advertising expense 
was approximately $83, $92 and $82 thousand in 1998, 1997, and 1996, 
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 1997 and 1996 amounts have been reclassified to conform with the 
1998 presentation.  The financial statements for 1997 and 1996 have also 
been restated to reflect the discontinuance of the Company's Technology 
Division (See Note 15).

(4)  Notes Receivable (continued)

(A)  The principal amount of this note may be reduced in accordance with
the terms of the note in the event of a sale of the fixed assets. 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 and is currently negotiating 
the collection of this note.

(5) Investment in Joint Venture

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 
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. The Company's interest in Plug 
Power may be reduced in certain circumstances. 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 Joint Venture"; 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 Joint Venture 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.  

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 that contribution. 
The Company paid approximately $191 thousand for the options, which mature 
in April 1999 ($250 thousand) and May 1999 ($2 million).  If the Company 
does not exercise its options, they will lapse.

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.  Such contributions will 
increase the Company's total contributions to Plug Power (including 
contributions of cash, assets, research credits, and a below market 
lease) to $11.75 million over the period commencing on June 27, 1997, 
and ending on March 31, 1999.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(5) Investment in Joint Venture (continued)

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.

The Company has recorded its proportionate share of Plug Power's losses 
to the extent of its recorded investment in Plug Power (including the 
foregoing obligation to contribute an additional $4 million through 
March 31, 1999).  

At September 30, 1998, the difference between the carrying value of the 
Company's investment in Plug Power and its interest in the underlying 
equity consists of the following:

(6) Income Taxes

Deferred tax assets and liabilities are determined based on the temporary 
differences between the financial statement and tax bases of assets and 
liabilities as measured by the enacted tax rates.

(8) 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 (8.5% at 
September 30, 1998) or LIBOR plus 2.5% (7.875% at September 30, 1998), and 
a $1 million equipment loan/lease line of credit at an interest rate of 
LIBOR plus 2.75% (8.125% at September 30, 1998). The lines of credit 
expire on January 31, 2000.  No amounts were outstanding under these lines 
at September 30, 1998 and 1997.

The Industrial Development Agency for the Town of Colonie has agreed to 
issue $6 million in Industrial Development Revenue ("IDR") Bonds on behalf 
of the Company to assist in the construction of a new building for 
Advanced Products and the Company's corporate staff and renovation of 
existing buildings leased to Plug Power.  The construction project is due 
to be completed in April 1999.  First Albany Companies Inc. ("FAC"), which 
owns 34% of the Company's stock, will underwrite the sale of the IDR 
Bonds.  Proceeds of the IDR Bonds will be deposited with a trustee for the 
bondholders.  The Company may draw the bond proceeds to cover qualified 
project costs.  The bond closing is expected to be completed on or about 
December 17, 1998.  FAC will receive no fees for underwriting the IDR 
Bonds but will be reimbursed for its out-of-pocket costs. 

Additionally, KeyBank has agreed to issue a $6 million direct pay letter 
of credit to enhance the $6 million IDR Bonds to be issued on the 
Company's behalf on or about December 17, 1998.  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.

approximately $186 thousand for net proceeds of approximately $6,992 
thousand.  The Company will use some or all of the proceeds of the 
offering for investment in and/or loans to Plug Power.  In addition, some 
proceeds may be used for acquisitions for the Company's core businesses, 
efforts to increase market share, working capital, general corporate 
purposes and other capital expenditures.  

The Company had a Restricted Stock Incentive Plan, which awarded 
restricted Common Stock of the Company to officers and other key 
employees. The Plan expired on December 31, 1994 and no further awards may 
be granted. In fiscal year 1995, 32,500 shares were granted, valued at 
$14,375 based on the market value of the stock at the date of grant. For 
accounting purposes, the value of the grants represents compensation, 
which has been deferred and is being amortized over the 5-year and 10-year 
vesting periods.  The shares granted during 1995 were recorded as a 
component of Shareholders' Equity. The value of the grants, net of 
accumulated amortization and write-offs, was $0 at September 30, 1998 and 
$2 thousand at September 30, 1997.

(10) Earnings per Share (continued)

During fiscal 1998, options to purchase 404,915 shares of common stock at 
prices ranging from $2.44 to $6 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.  
Therefore, no potential common shares are included in the computation.  
The options, which expire between December 20, 2006 and August 31, 2008, 
were still outstanding at September 30, 1998. During fiscal 1997, 
options to purchase 195,000 shares of common stock at a price of $3.44 
per share were outstanding but were not included in the computation of 
Earnings per Share-assuming dilution because the exercise price was 
greater than the average market price of the common shares.  Therefore, 
no potential common shares are included in the computation.  The 
options, which expire August 27, 2007 were still outstanding at 
September 30, 1997. 

(11) Stock Option Plan

During December 1996, the shareholders approved a new stock incentive 
plan. The 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 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 plan.  During 1998 and 1997, the number of shares available 
under the plan increased to 719,640 and 600,000 shares respectively.  
Under the 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.

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 1998 and 1997, 
respectively.  The expected volatility was 102% in 1998 and 78% and in 
1997.  The expected life of the options is 5 years. The risk free interest 
rate ranges from 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 1998 or 1997.  
Had compensation cost and fair value been determined pursuant to FAS 123, 
net loss would increase 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

(11) Stock Option Plan (continued)

diluted loss per share would increase from $(.73) to $(.80) in 1998 and 
basic and diluted earnings per share would decrease from $0.80 to $0.76 in 
1997.  The weighted average fair value of options granted during 1998 and 
1997 for purposes of FAS 123, is $4.70 and $1.96 per share, respectively. 

Activity with respect to the plan is as follows:

(12) 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 $83, $179 and $187 thousand for 1998, 1997 and 1996, respectively.

(13) Commitments and Contingencies

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. 

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.

(14)  Related Party Transactions (continued)

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. Services billed by the Company are for cost reimbursement only.

Billings under these agreements amounted to $661 and $65 thousand for 1998 
and 1997, respectively. Amounts receivable from Plug Power under these 
agreements are included in the balance sheet caption "Accounts receivable 
- - Joint Venture".  During 1998, the Company entered into leases for 
manufacturing, laboratory and office space which expire at various dates 
through September 30, 2008.  

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 1996, the Company made several rental payments for laboratory space 
to an officer/director of the Lawrence Insurance Group Inc. ("LIG") and 
purchased various insurance coverage from LIG or companies owned directly 
or indirectly by LIG totaling $453 thousand.  At September 30, 1996, 
several subsidiaries of LIG collectively owned approximately 16.8% of the 
Company's common stock.  

(15) 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, 1997, 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.

The Company's United Telecontrol Electronics, Inc. ("UTE") subsidiary, the 
sole component of the Defense/Aerospace segment, filed for voluntary 
bankruptcy under Chapter 11 of the Federal Bankruptcy Code in April 1994.

During October 1994, UTE commenced an orderly liquidation and final court

approval occurred during the third quarter of fiscal 1996. Accordingly, 
the Company no longer includes Defense/Aerospace among its reportable 
business segments, and since 1994 UTE has been reported as a discontinued 
operation, and accordingly the consolidated financial statements have been 
reclassified to report separately the net liabilities and operating 
results of the business.  The Company recorded the effect of the final 
liquidation of UTE during fiscal year 1996. Final adjustments to the 
Company's financial statements as a result of the UTE bankruptcy are 
reflected in income from discontinued operations.

Discontinued operations consist of the following:

(16) Sale of Division/Subsidiary (continued) 

received $2,600 thousand 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 $2,012 thousand 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, 1998.

ProQuip, Inc.

On November 22, 1994, the Company sold all of the outstanding capital 
stock of its ProQuip Inc. subsidiary to Phase Metrics of San Diego, CA. 

The Company received $13,250 thousand in cash from Phase Metrics and 
ProQuip forgave a $316 thousand intercompany debt due from the Company.  
The net proceeds from the sale were used to reduce term debt by $8,000 
thousand and to increase working capital by $3,776 thousand.

The sale resulted in a $6,779 thousand gain, which was recorded during the 
first quarter of fiscal year 1995.  In addition, $750 thousand of the net 
proceeds was escrowed to provide a fund for any indemnity payments that 
the Company may be obligated to pay Phase Metrics. As of February 22, 1996 
(the escrow expiration date), no claim had been filed, nor was the Company 
aware of any circumstances which might give rise to future claims. 
Accordingly, the Company recognized the remaining $750 thousand gain from 
the sale during the second quarter of fiscal 1996.

The reconciling items are the amounts of revenues earned and expenses 
incurred for corporate operations, which is not included in the segment 
information.   

(18) 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 (See Note 14). 

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. 

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.
