PART I

Item 1. BUSINESS

Recent Developments

We need an immediate infusion of equity capital to sustain our operations. We anticipate that our existing cash and cash resources will enable us to fund our
operations through only approximately January 15, 2003. We are operating under a forbearance agreement with Silicon Valley Bank which is currently enabling us to borrow minimal levels of
working capital from Silicon Valley Bank. On December 13, 2002, we executed a term sheet with an institutional investor to raise between $5 and $7 million of equity capital. The term
sheet contemplates that $3 to $5 million of the equity investment will be funded during the week of January 6, 2003 and the remaining $2 million will be funded promptly after the
registration statement we are required to file with the Securities and Exchange Commission is declared effective registering all of the underlying equity securities in this financing.

If
Silicon Valley Bank decides to discontinue lending to us or we are unable to close an equity financing with the institutional investor or other investors prior to January 15,
2003, we will be forced to furlough or permanently lay off a significant portion of our work force. This will have a material adverse effect on us. Under these circumstances, we may not be able to
continue our operations. Further, without additional cash resources, we may not be able to keep all or a significant portion of our operations going for a sufficient period of time to enable us to
sell all or portions of our assets or operations at other than distressed sale prices. Even if we are able to consummate the financing with the institutional investor prior to January 15, 2003
and retain a credit facility with Silicon Valley Bank, we may still require additional cash resources in the future to fund our anticipated operating losses, to grow, to develop new or enhance
existing products and services and to respond to competitive pressures. See "Management's Discussion and Analysis of Financial Condition and Results of OperationsLiquidity and Capital
Resources" below.

Under
the proposed terms of the term sheet with the institutional investor, we would issue shares of convertible preferred stock for $15,000 per share and warrants to purchase 5,000
shares of common stock for each share of convertible preferred stock issued. The preferred stock will be convertible into a number of shares of common stock equal to 15,000 divided by the conversion
price of the stock (which will initially be $1.50). The convertible preferred stock will accrue dividends of 8% per annum, increasing to 12% on January 1, 2004. Under the proposed terms of the
term sheet with the institutional investor, we may opt to pay the dividends in cash or in kind. Nevertheless, our current credit facility prohibits, and future credit facilities will likely prohibit,
the payment of any cash dividend. The dividend for the first year will be paid at the closing in shares of common stock, valued based on the conversion price of the preferred stock, and thereafter
will be paid on a quarterly basis. The warrants will be exercisable for a five-year term and will have an exercise price of $2.00 per share.

As
mentioned above, the term sheet with the institutional investor contemplates that we will issue between $3 million and $5 million of the convertible preferred stock at a
first closing during the week of January 6, 2003. The remaining $2 million will be funded promptly after the registration statement we are required to file to register the common stock
issuable upon conversion of the convertible preferred stock and exercise of the warrants is declared effective. We are required to file the registration statement within 30 days after the first
closing and use our best efforts to have the registration statement declared effective within 90 days after the first closing. If the registration statement is not declared effective within
120 days of the first closing, we will be obligated to pay to the investors liquidated damages equal to 1.5% of the amount invested for each 30-day period, beginning 90 days
after the first closing, that the registration statement is not effective.

If
we issue shares of common stock at a purchase price below the conversion price of the convertible preferred stock or the exercise price of the warrants, the conversion price and the
exercise price, as applicable, will be adjusted on a weighted average basis.

2

---

If
we consummate any private equity or equity-linked financing within 12 months after the first closing, the investors in our convertible preferred stock will have a right of
first offer to purchase all or part of that financing. In addition, if we enter into a private equity or equity-linked financing within 24 months after the first closing, the investors will
have the rights to exchange their shares of convertible preferred stock at the stated value of the securities issued in that financing.

To
date, the documentation relating to the financing with the institutional investor has been produced by counsel to the institutional investor but has not been finalized. There can be
no guarantee that we will be able to secure financing with the institutional investor on these or any other terms, or that we will be able to successfully close this financing and raise the
$5 million to $7 million contemplated by the term sheet.

Any
securities offered to the institutional investor will not be or have not been registered under the Securities Act of 1933 and may not be offered or sold in the United States absent
registration or an applicable exemption from the registration requirements.

Overview

SatCon was organized as a Massachusetts corporation in 1985 and reincorporated as a Delaware corporation in 1992. We are developing enabling technologies for the
emerging critical power marketplace where power quality and uninterruptible power are important. We design, develop and manufacture high-efficiency high power electronics and a variety of
standard and custom high-performance machines for specific applications. Our critical power products convert, store and manage electricity for businesses and consumers, the U.S. Government
and the military that require high-reliability electronics and controls and high-quality, uninterruptible power. We are utilizing our engineering and manufacturing expertise to develop
products we believe will be integral components of distributed power generation and power quality systems. Our specialty motors are typically designed and manufactured for unique customer requirements
such as high power-to-size requirements or high efficiency.

We
have been developing technology in power and energy management since our inception. Power and energy management is the combination of products and technology to improve the efficiency
of machines and systems in the generation, storage or usage of energy. During fiscal year 2002, we focused on the development of a 2.2 megawatt Rotary UPS system, a three phase utility multimode
inverter for on-site power generation and modular power control modules for potential application on an "all-electric" ship. In some critical power applications, customers
cannot afford even a millisecond of power outage. These potential customers will need and demand reliable power all the time.

Prior
to 1993, we were primarily funded through research and development contracts with the U.S. government. These contracts were directed at developing new technologies in motion
control, control software and electronics. Through this work, we built an engineering base in magnetics, motor/drive technology, digital signal processing and high-speed electronics. From
1993 to 1996, we expanded that base through commercially-funded research and development to include high-power electronics, high-density packaging and advanced materials.
Together, these engineering skills formed the foundation for our power and energy management technology. Since 1996, we have concentrated on employing that technology to solving market needs and
transitioning from technology development to product development and manufacturing.

Since
1996, our revenue has increased from $9.4 million, primarily from funded research and development, to $41.6 million in 2002, of which $30.8 million, or 74%,
was derived from product sales and the balance was from funded research and development and other revenue. We are also introducing new products, which we believe we can transition into commercial
production over the next few years, products such as our Rotary Uninterruptible Power Supplies, Power Conditioning Systems and Power Control Modules.

Since
1996, we have expanded our business and capabilities through several acquisitions. In January 1997, we acquired our MagMotor division, a manufacturer of custom and standard
electric motors. In April 1997, we acquired Film Microelectronics, Inc., a manufacturer of thin film substrates and hybrid microelectronics. In January 1999, we acquired Inductive
Components, Inc., a value-added supplier of customized electric motors, and Lighthouse Software, Inc., a supplier of control software for machine tools. We acquired HyComp, Inc.,
a manufacturer of hybrid microelectronics in April 1999 followed by Ling Electronics, Inc., a manufacturer of shaker vibration test systems, power converters, amplifiers and controllers,
which we acquired in October 1999. In November 1999, we acquired intellectual property, tooling and other assets from Northrop Grumman Corporation used in their power electronics
business area. In July 2001, we acquired substantially all of the assets of Inverpower Controls, Ltd., a manufacturer of power electronics and high-speed digital controls for
use in industrial power and power quality systems. Inverpower also has UL and CE certification capability. On September 27, 2002, we acquired the data conversion product line from Sipex
Corporation.

These
acquisitions have provided us with increased revenues, a manufacturing capability to transition our technology into commercial products, and a market presence from which we can
derive the need for new products based on our technology. Over the past five years, we have sought to expand our markets in power and energy management to include telecommunications, industrial
automation, semiconductor manufacturing, aircraft, high-reliability shipboard power conversion and controls and electric and hybrid-electric vehicles and distributed power generation. We sell our
current products into the following markets:

UPS and Power Quality


Revenues
for our fiscal years ended September 30, 2002, 2001 and 2000 were $41.6 million, $41.7 million and $31.1 million, respectively. We operate through
three business units, which sell these products as follows:



In
2002, we focused our new product development efforts on combining our high-power electronics and control systems into enabling components of critical power systems such as
our Rotary

---

Uninterruptible Power Supply (UPS) and Power Quality System, our Power Conditioning Systems for distributed power generation and Power Control Modules for use in the U.S. Navy's future
"all-electric" ships. In concentrating our efforts on these critical power systems, we focused our resources toward completing product development and building and testing prototypes. We
have also conducted customer surveys to understand market requirements. We have established some strategic relationships with key customers and suppliers, and have successfully demonstrated our UPS,
Power Quality and Distributed Power Generation products. We believe that there is a developing market demand for these products.

During
fiscal 2002, we also focused our efforts on developing our management team, cutting costs and reducing our cash burn rate. We added new members to our management team that we
believe will help enable us to accomplish our strategic objectives of completing our product development efforts while reducing our cost structure.

In
fiscal 2002, Mike Williams came in to serve as senior Vice-President and General Manager of SatCon Power Systems. Mike began his career with General Electric (GE) in 1969
in Lynn, Massachusetts developing large turbine and aircraft engines and most recently he managed the Industrial Systems Solutions division. Also joining us this past fiscal year was our new Chief
Financial Officer, Ralph
Norwood. Ralph worked for over twenty years at Polaroid Corporation where he served as both the vice president and treasurer and the vice president and controller of the corporation.

We
also focused our efforts in fiscal 2002 toward streamlining our costs. In our first quarter, we expended $7.9 million in cash with a loss of $5.3 million on revenues of
$8.3 million. The cash burn was due in part to spending primarily on product development and capital expenses related to our UPS and Power Quality products. We realized that such expenditures
would have to be reduced significantly given economic conditions. We immediately sought ways to reduce cash burn and reduce our loss position while attempting to recover our revenue growth.

We
reduced our cash burn to $5.0 million in the second quarter, $3.5 million in the third quarter and $2.1 million in the final quarter. We also improved our
earnings position by reducing our loss to $5.0 million in the second quarter, including a $1.5 million charge for restructuring, and to approximately $3.5 million in the last two
quarters. At the same time we increased revenue from $8.3 million in the first quarter to $11.2 million in the fourth quarter and a total for the year of $41.6 million.

Industry Background

We believe the markets for critical power products are entering a period of expansion. UPS and power quality; distributed power, such as on-site power
generation; "all-electric" ships and "fly-by-wire" aircraft that replace mechanical systems with electrical ones; hybrid-electric vehicles, that replace
conventional internal combustion engines with a combination of a smaller internal combustion engine and electric motors; among others, are product areas that are approaching commercialization. In the
United States, this expansion is being driven by several factors, including:

As
a result of market dynamics, power generation uncertainty and environmental concerns, business and government are seeking more reliable, cleaner and more cost-effective
solutions to their critical power needs. The demand for reliable, high-quality, cleaner power is creating a growing market for distributed power generation and power quality systems. All
of these systems require critical power products to convert, store and manage electricity. In order to be commercially viable and operate effectively, these critical power products must be highly
reliable, efficient, low-cost and compact. Many of these products must be highly customized to meet the evolving needs of the distributed power generation and power quality marketplace. We
believe this provides us with an opportunity to apply our technical expertise to meet these needs and to manufacture and supply critical power products. Market dynamics, power generation uncertainty
and environmental concerns have also lead to the development of the following markets:

Uninterruptible Power Supply and Power Quality Market

UPS systems maintain a predictable quality of electricity during power outages or periods of low power quality. These systems can be used as a replacement to the
electricity grid for an unlimited time, needing only to be refueled. In addition to their primary role of providing uninterruptible power in the absence of the grid, our UPS system is designed to work
in conjunction with the electricity grid to provide high quality power, without the fluctuations caused by power surges, sags and brownouts. These electrical disturbances can also cause system
malfunctions within automated industrial processes, data
centers or other industries with computer driven systems. As a result, UPS and power quality systems are used to support the operation of computer centers, manufacturing facilities and communication
and other electronic networks in the event of power losses and are particularly important to those users who operate 24 hours a day, seven days a week, or where there are critical operations
that cannot be interrupted even for one millisecond.

Currently,
when electrical power is lost or its quality drops, lead-acid batteries provide back-up electricity until a generator can be manually engaged.
Batteries have poor reliability and reduced life expectancy. The dangers of explosion and acid spills are additional environmental concerns associated with lead-acid batteries.

Distributed Power Generation Market

With the deregulation of the electric utility industry, the ability to offer new forms of electrical power generation such as distributed, on-site,
power generation is creating new markets, products and opportunities. Distributed power, that is power generated independent of the electric utility grid, locates power-generating capability closer to
the end user. The distributed generation of electrical power from clean diesels, microturbines, solar arrays, wind turbines or fuel cell systems is potentially an environmentally cleaner, more
efficient and more reliable means of producing electricity when compared to conventional generation and distribution methods. Distributed power generation systems can also alleviate congestion on
highly loaded utility distribution networks and offer an alternative to power line extensions in remote regions. Fuel cells, microturbines and photovoltaics are technologies that are being developed
by several companies to address the distributed power generation market.

Defense Systems Market

Defense systems require high reliability electronics. With the continuing electrification of modern defense systems, the need to distribute and manage electrical
power has become more critical. Aircraft, transportation and ship systems are becoming more sophisticated and the electronics required for these systems demand greater reliability and improved
performance in smaller packages. In some instances electrical systems are replacing entire mechanical systems to gain performance advantages and reduce overall maintenance costs.

While
aircraft systems continue to require high reliability electronics like those used in heads-up displays or cruise missile video electronics, new systems, like
"fly-by-wire" aircraft that employ increasing numbers of electrical systems to replace mechanical systems are being developed. New "all-electric" ships are being
designed to replace mechanical systems with electrical systems both in the distribution of electricity and the use of it in such applications as "all-electric" gun systems.

New
secure communication systems require higher speed amplifiers. New airborne mine sweeping equipment requires modern compact power conversion equipment. New radar systems require more
efficient electronics, and many of the defense electronics systems require vibration testing.

Hybrid-Electric Vehicles

Prices of oil and refined products will strongly influence the demand for hybrid-electric vehicles. In the last year, significant increases in crude oil and
gasoline prices have renewed a national public policy debate regarding substitute fuel sources. We believe these higher prices, if sustained, will increase demand for substitute fuel sources and may
result in regulatory incentives to develop and commercialize vehicles powered by alternative fuel sources.

We
believe that fuel cell hybrid-electric vehicles have the potential to be the leading alternative to internal combustion engines in meeting clean air initiatives while offering greater
driving range and performance than electric vehicles. Hybrid-electric vehicles can reduce air pollution while offering greater driving range and performance than electric vehicles. Hybrid-electric
vehicles function by creating mechanical energy from a source such as an internal combustion engine or fuel cell. The mechanical energy is then transformed into electricity by a generator and
transferred to an electric drive train, which propels the vehicle. Excess electricity is stored in an energy storage system consisting of a battery or flywheel. All hybrid-electric vehicles require
complex power and control electronics to convert, condition and manage electricity, as well as high-performance motors, electric drive trains and energy storage systems.

Our Solution

Our solution is to provide critical power products and systems that encompasses the following key attributes demanded by the critical power marketplace:



Strategy

Our strategy is to use our expertise and proprietary technologies to leverage SatCon into a position of leadership as a provider of critical power systems for a
variety of applications including UPS and power quality systems, alternative energy and distributed power generation systems, defense systems, clean transportation and industrial automation. Our
strategy to leverage ourselves into a leadership position is two-fold: first, since the power control system is an enabler for critical power products, we believe that our control system
expertise positions us to be a key supplier to the marketplace; second, we believe that we possess the enabling technology in power electronics, magnetics and software controls to position SatCon to
compete as an integrator of critical power systemsdeveloping innovative power systems using our power electronics and control software and integrating third party "best of breed" power
generation and energy storage.

Our
critical power customers include semiconductor fabricators, industrial manufacturers, defense and aerospace contractors, and transportation and communication systems. We believe that
by designing and developing our products with cross-market applications, our success should be less dependent upon
the adoption of a specific application or on the business of a single market participant. To accomplish our objective, we are also pursuing the following:

Products

We design, develop and manufacture high-efficiency, high-reliability and long-lived critical power products that convert,
store and manage electricity. We are using our electronics and manufacturing expertise to develop products that meet the high-reliability, high-efficiency, low-cost
and compact-size requirements of
the distributed power generation and power quality markets. Our products are sold through our three business units:

SatCon Power Systems

SatCon Power Systems manufactures and sells our high power line of critical power systems including our standard lines of high-performance motors for
the industrial machinery, factory automation and automotive markets; MagLev integrated suspension and motor systems; and Ling Electronics vibration test systems StarSine
amplifiers. It has also been developing a new line of commercial Rotary UPS Systems for back-up power and power quality, for which we have been completing product development and testing
over this past year; power conversion systems for distributed power generation which were in the final stages of development and UL compliance testing in fiscal year 2002 and Inverpower industrial and
commercial power conversion and conditioning products. Revenues for our fiscal years ended September 30, 2002, 2001 and 2000 from our Power Systems business unit were approximately
$19.9 million, $20.2 million and $14.1 million, respectively.

our fiscal years ended September 30, 2002, 2001 and 2000 from our Electronics business unit was approximately $10.9 million, $10.6 million and $8.3 million, respectively.
The following are descriptions of some of our products within the Electronics business unit:



SatCon Applied Technology

Our Applied Technology business unit designs and builds power conversion products, which include power electronics, high-efficiency machines and
control systems for a variety of defense and commercial applications. Our objective is to transition prototype development contracts into multiyear production programs. Revenue for our fiscal years
ended September 30, 2002, 2001 and 2000 from Applied Technology was approximately $10.8 million, $10.9 million and $8.7 million, respectively.

We
pursue development programs in areas where we have technical expertise and where we believe there is significant long-term production potential for the developed
technology. Technical disciplines represented at our Applied Technology business unit include electromechanics, digital and analog electronics, power electronics and electronic packaging, thermal
management, motor dynamics, materials, software development, control technology, and system integration. To date, SatCon Applied Technology has built products for use in distributed power generation,
energy storage and power quality, high performance electric machinery, transportation and defense systems, including components for military hybrid-electric vehicles, "all-electric" ships
and aircraft subsystems.

more information, you can visit our website at www.satcon.com.

Funded Research and Development

We perform funded research and development in connection with government programs and for third parties. We pursue funded research and development in areas where
we have technical expertise and where we believe there is significant commercial application for the developed technology. We have performed funded research and development in connection with the
development of each of our product areas.

11

---

We
also have specialized engineering expertise in the areas of power electronics, electromechanics, mechanical and thermal dynamics, system controls and microelectronic design. We have
leveraged
research and development funding from industry and government sources to design, develop and manufacture electronics for power conversion, amplification and storage, high-performance
electric motors, flywheel energy storage systems and system controls software. We continue to pursue industry and government funding to supplement the on-going development of our products.

In
1999, we entered into an agreement with the U.S. Department of Energy, or DOE, for the research, development and demonstration of a power conversion system for a new generation of
hybrid-electric vehicles. Under this government contract, we have been engaged to design a power conversion system that can be manufactured at high volume and low cost. We believe that the resulting
design will enable us to enhance our manufacturing capabilities to produce our power conversion products for distributed power generation systems. This program was funded half by us and half by DOE.
The total DOE approved budget for this program was $10.0 million through September 29, 2002. As of September 30, 2002, revenues for this program had totaled $2.5 million in
fiscal 2002, $3.1 million in fiscal 2001, $3.4 million in fiscal 2000 and $1.0 million in fiscal 1999. We expect to complete final hardware deliveries in the first half of fiscal
year 2003.

New Product Opportunities

Rotary Uninterruptible Power Supply (UPS) Systems

During fiscal year 2002, we continued to work on completing the development of a line of Rotary Uninterruptible Power Supply, or UPS, systems for sale as back up
power supplies and power quality systems. Our line of Rotary UPS systems are designed to provide both power quality and UPS functions in power ranges from 250 kilowatts to 2.2 megawatts and beyond in
single or multiple unit systems. For comparison, 2.2 megawatts would be enough power to supply 440 homes using an average of 5kw of power. In fiscal year 2002, we concentrated on completing the
development and test of the 2.2 megawatt system for industrial and manufacturing operations.

GRAPHIC

SatCon's 2.2 Megawatt Rotary UPS System

Our
Rotary UPS product combines a diesel generator, a flywheel energy storage system, electronics and a proprietary control system into an uninterruptible power supply. We believe that
this system is an attractive alternative to lead-acid battery based UPS systems due to its seamless transition during power outages, increased reliability, longer life and the ability to
operate effectively in remote locations.

Power Conditioning System

We have developed modular power conditioning systems such as our Three Phase Utility Interactive Multi-Mode Inverter for use in connection with large, commercial
sized, fuel cell or microturbine distributed power generation systems that produce power ranging from 200 kilowatts to 5 megawatts. Our power conditioning systems are designed to convert the DC power
generated by an alternative energy source, such as a fuel cell, into useable AC power. They also provide the interface with the electric utility grid, an energy storage device, like a battery or
flywheel, and the end user applications. These units use a technology that allows them to be combined and scaled to handle high-power requirements. We introduced this product during our
2002 fiscal year.

GRAPHIC

SatCon's Three Phase Utility Interactive Multi-Mode Inverter (UL 1741 Compliant)

In
2002, our Three Phase Utility Interactive Multi-Mode Inverter was determined to be in compliance with the UL 1741 "Standard for Inverters, Converters, and Controllers for
Use in Independent Power Systems." At that time, the SatCon power inverter was the highest power rated, on-site generation inverter to comply with the UL 1741 Standard. By meeting the UL
1741 requirements, we believe that our Power Conditioning Systems are well-positioned to become the leading choice for customers
interested in creating their own distributed power using fuel cells in conjunction with, or completely separate from, the utility grid. In addition to fuel cell applications, these UL compliant
inverters are designed to be compatible with photovoltaics, microturbines and other on-site power generation systems.

Power Control Modules

As part of a defense contractor team that includes General Atomics and Gibbs and Cox, we have been developing an Integrated-Fight-Through-Power System for
potential application to the U.S. Navy's "all-electric" ship. As part of the most recent program phase, awarded in late fiscal year 2002, we are under contract to deliver modular,
electrical power converter and control assemblies, or Power Control Modules for land testing. The next phase of the program requires us to deliver power control modules for installation on the RV
Triton, a British research vessel, for at-sea testing. As part of the Navy's on-going development of the "all-electric" ship platform, we have been awarded
approximately $12.0 million in product development funding to date, $8.9 million of which was awarded in fiscal 2002.

SatCon's Power Control Modules as Components of the US Navy's Integrated-Fight-
Through-Power System

Developing methods for distributing and converting power from large-scale turbines to end use applications aboard a ship, we believe, is an example of how
distributed power can become the future of electrical power generation and distribution for a wide range of applications. We believe that the technology developed by us in connection with the
Integrated Fight-Through-Power System will have other commercial applications. We also believe that our involvement with the Integrated-Fight-Through-Power System program positions us to become a more
traditional supplier of advanced ship power converters for future "all-electric" ship and other Navy shipboard applications.

Significant Customers

The U.S. Department of Defense accounted for 5.7%, 6.8% and 9.8% of our total revenue for our fiscal years ended September 30, 2002, 2001 and 2000,
respectively. For our fiscal years ended September 30, 2002, 2001 and 2000, revenue from the U.S. Department of Energy accounted for 6.1%, 7.4% and 11.5% of our total revenue, respectively. For
our fiscal years ended September 30, 2002, 2001
and 2000, revenue from Applied Materials accounted for 4.7%, 8.3% and 10.6% of our total revenue, respectively. For our fiscal years ended September 30, 2002, 2001 and 2000, revenue from
General Atomics accounted for 12.0%, 9.4% and 1.7% of our total revenue, respectively. The loss of any one or more of these customers would have a material adverse effect on SatCon.

Research and Development

We believe that the continued and timely development of new products and enhancements to our existing products is necessary to maintain our competitive position.
We use technologies developed by our business units, together with information supplied by our distributors and customers, to design and develop new products and product enhancements and to reduce the
time-to-market for our products.

During
the fiscal year ended September 30, 2002, $10.8 million, or 26%, of our revenue was attributable to research and development activities funded by commercial
customers and U.S. government agency sponsors. Under the agreements funded by the U.S. government, the government retains a royalty-free license to use the technology developed for
government purposes and we retain exclusive rights to the technology for commercial and industrial applications. The rights to technology developed under contracts funded by commercial customers are
negotiated on a case-by-case basis. We expended $5.7 million, $6.2 million and $3.5 million on internally-funded research and development during our fiscal
years ended September 30, 2002, 2001 and 2000, respectively. During our fiscal year ended September 30, 2002, our most concentrated effort was directed toward building the power inverter
for an on-site power generation system and our 250 kilowatt and 2.2 megawatt rotary UPS and power quality systems.

Sales and Marketing

We sell our products and services both domestically and internationally through our direct sales force and through independent distributors and representatives.
Our direct sales staff manages our key customer accounts, provides customer support and identifies significant market opportunities in their respective markets.

Each
of our three divisions manages its own marketing organization and is responsible for developing sales and advertising literature, such as product announcements, catalogs, brochures
and magazine articles in trade and other publications. Publication of significant events or material information is handled through our corporate office.

We
maintain close contact with our customers' design and engineering staffs in order to provide the appropriate products for our customers' applications. We maintain this close working
relationship with our customers throughout the life of a product, and we believe that it has been a key component of our customers' satisfaction.

We
compete for and market our research and development contracts through several methods, including pursuing new and existing customer relationships in the commercial and government
sectors, responding to Small Business Innovative Research calls for proposals and calls for proposals listed in the daily publication,Commerce Business
Daily, seeking to maintain a strong technical reputation within the community, responding to unsolicited requests for proposals and through our Internet site.

Backlog

Our backlog consists primarily of product development contracts, orders for critical power systems, electronics and motion control products. At
September 30, 2002, our backlog was approximately $16 million. Of this amount, approximately $13 million is scheduled to be shipped during fiscal year 2003. These amounts exclude
approximately $2 million of UPS orders booked in November 2001 but which are unlikely to be shipped. Many of our contracts and sales orders may be canceled at any time with limited or no
penalty. In addition, contract awards may be subject to funding approval from the U.S. government and commercial entities, which involves political, budgetary and other considerations over which we
have no control. Our backlog at September 30, 2001 was $21.0 million. We believe that our backlog at any time should not be used as an indication of future revenue.

Competition

We believe that competitive performance in the marketplace for critical power products depend upon several factors, including product price, technical innovation,
product quality and reliability, range of products, customer service and technical support. We believe our technical innovation emphasizing product performance and reliability, supported by our
commitment to strong customer service and technical support, enables us to continue to compete successfully against the following competitors:



Some
of our competitors have substantially greater financial resources than we do and could devote greater resources to the development, promotion, sale and support of their products and
may have more manufacturing expertise and capacity. In addition, some of our competitors have more extensive customer bases and broader customer relationships than we do.

Manufacturing

We manufacture our products at our facilities located in Marlborough, Massachusetts; Worcester, Massachusetts and Burlington, Ontario, Canada. We believe our
existing manufacturing capacity is sufficient to meet our current needs. Our goal is to mass manufacture high volume, low-cost products as our products gain market acceptance and the
markets for our products develop. We believe that most of the raw materials used in our products are readily available from a variety of vendors. Additionally, we design and develop our products to
use commodity parts in order to simplify the manufacturing process. We have a semi-automated production line in our Marlborough, Massachusetts facility. We intend to add additional
production lines for our products in the future as demand dictates and our revenues enable. We have made and expect to continue to make technological improvements that reduce the costs to manufacture
our products.

Our
manufacturing facilities are subject to numerous environmental laws and regulations, particularly with respect to industrial waste and emissions. Compliance with these laws and
regulations has not had a material impact on our capital expenditures or competitive position.

believe that most of the raw materials used in our products are readily available from a variety of vendors. Additionally, we design and develop our products to use commodity parts in
order to simplify the manufacturing process.

Intellectual Property

Our success and competitiveness depend on our ability to develop and maintain the proprietary aspects of our technology and operate without infringing on the
proprietary rights of others. We rely on a combination of patent, trademark, trade secret and copyright law and contract restrictions to protect the proprietary aspects of our technologies. We seek to
limit disclosure of our intellectual property by requiring employees, consultants, and any third parties with access to our proprietary information to execute confidentiality agreements and by
restricting access to that information.

As
of December 10, 2002, we held 75 U.S. patents and had 10 patent applications pending with the U.S. Patent and Trademark Office. We have also obtained corresponding patents in the rest
of North America, Europe and Asia. In addition, we have a non-exclusive, royalty-free license for non-automotive applications for 38 other patents that were issued
to our employees and subsequently assigned to DaimlerChrysler in connection with the now completed Chrysler Patriot racecar project. The expiration dates of our patents range from 2007 to 2021, with
the majority expiring after 2016.

In
1997, we granted Beacon Power Corporation a perpetual, worldwide, royalty-free, exclusive right and license to our flywheel technology for stationary, terrestrial
applications. Beacon Power was formed as a spin off of SatCon Technology Corporation. In November of 2000, Beacon Power became a publicly traded company. In September of 2001 we made a
5,000,000-share distribution of our Beacon Power ownership to our stockholders and currently own approximately 11% of Beacon Power following that distribution.

Many
of the U.S. patents described above are the result of retaining ownership of inventions made under U.S. government-funded research and development programs. As a qualifying small
business, we have retained commercial ownership rights to proprietary technology developed under various U.S. government contracts and grants, including small business innovation research contracts.
With respect to any invention made with government assistance, the government has a nonexclusive, nontransferable, irrevocable, paid-up license to use the technology or have the technology
employed for or on behalf of the U.S. government throughout the world. Under certain conditions, the U.S. government also has "march-in rights." These rights enable the U.S. government to
require us to grant a nonexclusive, partially exclusive, or exclusive license in any field of use to responsible applicants, upon terms that are reasonable under the circumstances.

Government Regulation

We presently are subject to various federal, state and local laws and regulations relating to, among other things, safe working conditions, handling and disposal
of hazardous and potentially hazardous substances and emissions of pollutants into the atmosphere. To date, we believe that we have obtained all necessary government permits and have been in
substantial compliance with all of these applicable laws and regulations.

Government Contracts

We act as a prime contractor or major subcontractor for many different U.S. government programs, including those that involve the development of
electro-mechanical transportation, navigation and energy-related products. Over its lifetime, a program may be implemented by the award of many individual contracts and subcontracts, or contracts with
option years, or partially funded contracts.

U.S.
government contracts include provisions permitting termination, in whole or in part, without prior notice, at the U.S. government's discretion. The U.S. government generally pays
compensation for work actually done and commitments made at the time of termination, and some allowance for profit on the work performed. The U.S. government may also terminate for default in
performance and pay only the value delivered to the U.S. government. It can also hold the contractor responsible for reprocurement costs.

Our
government contract business is also subject to specific procurement statutes and regulations and a variety of socio-economic and other factors. Failure to comply with these
regulations and requirements could lead to loss of contract or suspension or debarment from U.S. government contracting or subcontracting for a period of time. Examples of these statutes and
regulations are those related to procurement integrity, export control, employment practices, the accuracy of records and the recording of costs.

Sales
to the U.S. government may be affected by changes in research interests in the areas in which we engage, changing government department budgets, and changing procurement policies.

Employees

At September 30, 2002, we had a total of 275 full-time employees, 5 part-time employees and 29 contract employees. Of the total, 90
persons were employed in engineering, 153 in manufacturing, 42 in administration and 24 in sales and marketing. Our future success depends in large part on the continued service of our key technical
and senior management personnel, and on our ability to attract, retain and motivate qualified employees, particularly those highly skilled design, process and test engineers involved in the
manufacture of existing products and the development of new products and
processes. The competition for such personnel is intense, and the loss of key employees could have a material adverse effect on us. None of our employees are represented by a union. We believe that
our relations with our employees are good.

We need an immediate infusion of equity capital to sustain our operations. We anticipate that our existing cash and cash resources will enable us to fund our
operations through only approximately January 15, 2003. We are operating under a forbearance agreement with Silicon Valley Bank which is currently enabling us to borrow minimal levels of
working capital from Silicon Valley Bank. On December 13, 2002, we executed a term sheet with an institutional investor to raise between $5 and $7 million of equity capital. The term
sheet contemplates that $3 to $5 million of the equity investment will be funded during the week of January 6, 2003 and the remaining $2 million will be funded promptly after the
registration statement we are required to file with the Securities and Exchange Commission is declared effective registering all of the underlying equity securities in this financing.

If
Silicon Valley Bank decides to discontinue lending to us or we are unable to close an equity financing with the institutional investor or other investors prior to January 15,
2003, we will be forced to furlough or permanently lay off a significant portion of our work force. This will have a material adverse effect on us. Under these circumstances, we may not be able to
continue our operations. Further, without additional cash resources, we may not be able to keep all or a significant portion of our operations going for a sufficient period of time to enable us to
sell all or portions of our assets or operations at other than distressed sale prices. Even if we are able to consummate the financing with the institutional investor prior to January 15, 2003
and retain a credit facility with Silicon Valley Bank, we may still require additional cash resources in the future to fund our anticipated operating losses, to grow, to develop new or enhance
existing products and services and to respond to competitive pressures. See "Management's Discussion and Analysis of Financial Condition and Results of OperationsLiquidity and Capital
Resources" below.

Under
the proposed terms of the term sheet with the institutional investor, we would issue shares of convertible preferred stock for $15,000 per share and warrants to purchase 5,000
shares of common stock for each share of convertible preferred stock issued. The preferred stock will be convertible into a number of shares of common stock equal to 15,000 divided by the conversion
price of the stock (which will initially be $1.50). The convertible preferred stock will accrue dividends of 8% per annum, increasing to 12% on January 1, 2004. Under the proposed terms of the
term sheet with the institutional investor, we may opt to pay the dividends in cash or in kind. Nevertheless, our current credit facility prohibits, and future credit facilities will likely prohibit,
the payment of any cash dividend. The dividend for the first year will be paid at the closing in shares of common stock, valued based on the conversion price of the preferred stock, and thereafter
will be paid on a quarterly basis. The warrants will be exercisable for a five-year term and will have an exercise price of $2.00 per share.

24

---

As
mentioned above, the term sheet with the institutional investor contemplates that we will issue between $3 million and $5 million of the convertible preferred stock at a
first closing during the week of January 6, 2003. The remaining $2 million will be funded promptly after the registration statement we are required to file to register the common stock
issuable upon conversion of the convertible preferred stock and exercise of the warrants is declared effective. We are required to file the registration statement within 30 days after the first
closing and use our best efforts to have the registration statement declared effective within 90 days after the first closing. If the registration statement is not declared effective within
120 days of the first closing, we will be obligated to pay to the investors liquidated damages equal to 1.5% of the amount invested for each 30-day period, beginning 90 days
after the first closing, that the registration statement is not effective.

If
we issue shares of common stock at a purchase price below the conversion price of the convertible preferred stock or the exercise price of the warrants, the conversion price and the
exercise price, as applicable, will be adjusted on a weighted average basis.

If
we consummate any private equity or equity-linked financing within 12 months after the first closing, the investors in our convertible preferred stock will have a right of
first offer to purchase all or part of
that financing. In addition, if we enter into a private equity or equity-linked financing within 24 months after the first closing, the investors will have the rights to exchange their shares
of convertible preferred stock at the stated value of the securities issued in that financing.

To
date, the documentation relating to the financing with the institutional investor has been produced by counsel to the institutional investor but has not been finalized. There can be
no guarantee that we will be able to secure financing with the institutional investor on these or any other terms, or that we will be able to successfully close this financing and raise the
$5 million to $7 million contemplated by the term sheet.

Any
securities offered to the institutional investor will not be or have not been registered under the Securities Act of 1933 and may not be offered or sold in the United States absent
registration or an applicable exemption from the registration requirements.

Overview

SatCon was organized as a Massachusetts corporation in 1985 and reincorporated as a Delaware corporation in 1992. We are developing enabling technologies for the
emerging critical power marketplace where power quality and uninterruptible power are important. We design, develop and manufacture high-efficiency high power electronics and a variety of
standard and custom high-performance machines for specific applications. Our critical power products convert, store and manage electricity for businesses and consumers, the U.S. Government
and the military that require high-reliability electronics and controls and high-quality, uninterruptible power. We are utilizing our engineering and manufacturing expertise to develop
products we believe will be integral components of distributed power generation and power quality systems. Our specialty motors are typically designed and manufactured for unique customer requirements
such as high power-to-size requirements or high efficiency.

We
have expanded our business and capabilities through the following acquisitions:

In
addition, in November 1999, we acquired intellectual property, tooling and other assets from Northrop Grumman Corporation enabling us to manufacture and sell electric
drivetrains and, in September 2002, we acquired certain intellectual property, equipment and other assets from Sipex Corporation to expand our high-reliability data conversion
product line. See Note R to our Consolidated Financial Statements in this Annual Report on Form 10-K for more information regarding our acquisitions.

Critical Accounting Policies and Significant Judgments and Estimates

Our discussion and analysis of our financial condition and results of our operations are based on our consolidated financial statements, which have been prepared
in accordance with accounting principles generally accepted in the United States. The preparation of these consolidated financial statements requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements and the reported revenues and expenses during the
reporting periods. On an ongoing basis, management evaluates its estimates and judgments, including those related to revenue recognition, receivable reserves, inventory reserves, investment in Beacon
Power Corporation, goodwill and intangible assets and income taxes. Management bases its estimates on historical experience and on various other factors that are believed to be reasonable under the
circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results may differ
from these estimates under different assumptions or conditions.

Revenue Recognition

The significant accounting policies that management believes are most critical to aid in fully understanding and evaluating our reported financial results include
the following:

We
recognize revenue from product sales in accordance with SEC Staff Accounting Bulletin No. 101,Revenue Recognition. Product
revenue is recognized when there is persuasive evidence of an arrangement, the fee is fixed or determinable, delivery of the product to the customer has occurred and we have determined that collection
of the fee is probable. Title to the product generally passes upon shipment of the product, as the products are shipped FOB shipping point, except for certain foreign shipments. If the product
requires installation to be performed by us, all revenue related to the product is deferred and recognized upon the completion of the installation. We provide for a warranty reserve at the time the
product revenue is recognized.

We
perform funded research and development and product development for commercial companies and government agencies under both cost reimbursement and fixed-price contracts. Cost
reimbursement contracts provide for the reimbursement of allowable costs and, in some situations, the payment of a fee. These contracts may contain incentive clauses providing for increases or
decreases in the fee depending on how costs compare with a budget. On fixed-price contracts, revenue is generally recognized on the percentage of completion method based upon the proportion of costs
incurred to the total estimated costs for the contract. Revenue from reimbursement contracts is recognized as services are performed. In each type of contract, we receive periodic progress payments or
payment upon

26

---

reaching interim milestones and retain the rights to the intellectual property developed in government contracts. All payments to us for work performed on contracts with agencies of the U.S.
government are subject to audit and adjustment by the Defense Contract Audit Agency. Adjustments are recognized in the period made. When the current estimates of total contract revenue and contract
costs for commercial product development contracts indicate a loss, a provision for the entire loss on the contract is recorded. Any losses incurred in performing funded research and development
projects are recognized as funded research and development expenses as incurred. As of September 30, 2002 and 2001, we have accrued $0.2 million and $0.1 million, respectively,
for anticipated contract losses on commercial contracts. For the fiscal year ended September 30, 2002 and 2001, revenue from commercial contracts, which represents other revenue, is included in
funded research and development and other revenue and amounted to $0.2 million and $0.7 million, respectively.

Cost
of product revenue includes cost of product revenue including material, labor and overhead. Costs incurred in connection with funded research and development and other revenue
arrangements and other revenue are included in funded research and development and other revenue expenses. For the fiscal year ended September 30, 2002 and 2001, costs and expenses from
commercial contracts, which represents other revenue expenses, are included in funded research and development and other revenue expenses and amounted to $0.2 million and $0.5 million,
respectively.

Deferred
revenue consists of payments received from customers in advance of services performed, product shipped or installation completed.

Unbilled
contract costs and fees represent revenue recognized in excess of amounts billed due to contractual provisions or deferred costs that have not yet been recognized as revenue or
billed to the customer. These amounts included retained fee and unliquidated costs totaling $0.1 and $0.2 million at September 30, 2002 and 2001, respectively.

Accounts Receivable

Accounts receivable are reduced by an allowance for amounts that may become uncollectible in the future. The estimated allowance for uncollectible amounts is
based primarily on a specific analysis of accounts in the receivable portfolio and historical write-off experience. While management believes the allowance to be adequate, if the financial
condition of our customers were to deteriorate, resulting in impairment of their ability to make payments, additional allowances may be required.

Inventory

We value our inventory at the lower of actual cost to purchase and/or manufacture the inventory or the current estimated market value of the inventory. We
periodically review inventory quantities on hand and record a provision for excess and/or obsolete inventory based primarily on our estimated forecast of product demand, as well as based on historical
usage. Due to the custom and specific nature of certain of our products, demand and usage for products and materials can fluctuate significantly. A significant decrease in demand for our products
could result in a short-term increase in the cost of inventory purchases and an increase of excess inventory quantities on hand. In addition, our industry is characterized by rapid
technological change, frequent new product development, and rapid product obsolescence that could result in an increase in the amount of obsolete inventory quantities on hand. Therefore, although we
make every effort to ensure the accuracy of our forecasts of future product demand, any significant unanticipated changes in demand or technological developments could have a significant impact on the
value of our inventory and our reported operating results.

Investment in Beacon Power Corporation

During substantially all of the fiscal year ended September 30, 2001, we accounted for our investment in Beacon Power Corporation under the equity method
of accounting and recorded $5.1 million of losses from Beacon Power. On September 28, 2001, we distributed 5,000,000 shares of

27

---

Beacon Power common stock to our stockholders. Upon the distribution of the 5,000,000 shares, we recorded the distribution of the 5,000,000 shares as a reduction of additional paid-in
capital based on the book value per share prior to the distribution, or $0.59 per share. After the distribution, we owned 4,705,910 shares, or approximately 11.0%, of Beacon Power's outstanding voting
stock. Additionally, we have determined that we do not have the ability to exercise significant influence over the operating and financial policies of Beacon Power and, therefore, now account for our
investment in Beacon Power using the fair value method as set forth in Statement of Financial Accounting Standards (SFAS) No. 115,Accounting for Certain Debt and Equity
Securities.We are no longer required to record our share of any losses from Beacon Power and the investment is carried at fair value and designated as available for sale and
any unrealized holding gains or losses are to be included in stockholders' equity as a component of accumulated other comprehensive income/(loss). As of September 30, 2002, the shares of Beacon
Power common stock held by us had a fair value of $0.8 million and we recorded an unrealized loss of $6.4 million in stockholders' equity as a component of accumulated other
comprehensive income/(loss) during the fiscal year ended September 30, 2002. As of September 30, 2002, the fair market value of Beacon Power's common stock was $0.17 per share. Our cost
basis in our investment in Beacon Power's common stock was $0.59 per share. As of September 30, 2002, we believe the decline in market value represents an other than temporary decline because,
among other things, the market value has been less than cost since March 2002 and there is some uncertainty of the financial condition and near-term prospects of Beacon Power and,
accordingly, have recorded an other than temporary write-down of our investment in Beacon Power of $1.4 million. Additionally, we have a warrant to purchase 173,704 shares of Beacon
Power's common stock that has an exercise price of $1.25 per share and expires in 2005. We account for this warrant in accordance with SFAS No. 133 and, therefore, record the warrant at its
fair value and record any changes in value in our statement of operations. As of September 30, 2002, the warrant to purchase Beacon Power common stock had a fair value of $14,365 and is
included in warrants to purchase common stock on the accompanying balance sheet.

Goodwill and Intangible Assets

Purchase accounting requires extensive use of accounting estimates and judgments to allocate the purchase price to the fair market value of the assets purchased
and liabilities assumed. We have accounted for our acquisitions using the purchase method of accounting. Values were assigned to goodwill and intangible assets based on third-party independent
valuations, as well as management's forecasts and projections that include assumptions related to future revenue and cash flows generated from the acquired assets.

Effective
October 1, 2001, we adopted the provisions of SFAS No. 142,Goodwill and Other Intangible Assets. This statement
affects our treatment of goodwill and other intangible assets. The statements require that goodwill existing at the date of adoption be reviewed for possible impairment and that impairment tests be
periodically repeated, with impaired assets written down to fair value. Additionally, existing goodwill and intangible assets must be assessed and classified within the statement's criteria.
Intangible assets with finite useful lives will continue to be amortized over those periods. Amortization of goodwill and intangible assets with indeterminable lives will cease.

We
completed the first step of the transitional goodwill impairment test based on the amount of goodwill as of the beginning of fiscal year 2002, as required by SFAS No. 142. We
utilized a third party
independent valuation to determine the fair value of each of the reporting units based on a discounted cash flow income approach. Based on the results of the first step of the transitional goodwill
impairment test, we have determined that the fair value of each of the reporting units exceeded their carrying amounts and, therefore, no goodwill impairment existed as of October 1, 2001. As a
result, the second step of the transitional goodwill impairment test was not required to be completed. We performed a goodwill impairment test on the amount of goodwill as of the beginning of our
fiscal fourth quarter 2002, as required by SFAS No. 142 on an annual basis. We again utilized a third party

28

---

independent valuation to determine the fair value of each of the reporting units based on a discounted cash flow income approach. The income approach indicates the fair value of a business enterprise
based on the discounted value of the cash flows that the business can be expected to generate in the future. This analysis is based upon projections prepared by us and data from sources of publicly
available information available at the time of preparation. There will usually be differences between estimated and actual results as events and circumstances frequently do not occur as expected, and
those differences may be material. Based on the results of the first step of the annual goodwill impairment test, we have determined that the fair value of each of the reporting units exceeded their
carrying amounts and, therefore, no goodwill impairment existed as of the beginning of our fiscal fourth quarter 2002. As a result, the second step of the annual goodwill impairment test was not
required to be completed. We will continue to perform a goodwill impairment test on an annual basis.

We
did not record expense related to the amortization of goodwill during the fiscal year ended September 30, 2002. We recorded expense related to the amortization of goodwill of
$0.6 million during the fiscal year ended September 30, 2001. We have determined that all of our intangible assets have finite lives and, therefore, we have continued to amortize our
intangible assets. We recorded expense related to the amortization of our intangible assets of $0.6 million and $0.7 million during the fiscal year ended September 30, 2002 and
2001, respectively.

Accounting for Income Taxes

The preparation of our consolidated financial statements requires us to estimate our income taxes in each of the jurisdictions in which we operate, including
those outside the United States, which may be subject to certain risks that ordinarily would not be expected in the United States. The income tax accounting process involves estimating our actual
current exposure together with assessing temporary differences resulting from differing treatment of items, such as deferred revenue, for tax and accounting purposes. These differences result in the
recognition of deferred tax assets and liabilities. We must then record a valuation allowance to reduce our deferred tax assets to the amount that is more likely than not to be realized.

Significant
management judgment is required in determining our provision for income taxes, our deferred tax assets and liabilities and any valuation allowance recorded against deferred
tax assets. We have recorded a full valuation allowance against our deferred tax assets of $29.1 million as of September 30, 2002, due to uncertainties related to our ability to utilize these
assets. The valuation allowance is based on our estimates of taxable income by jurisdiction in which we operate and the period over which our deferred tax assets will be recoverable. In the event that
actual results differ
from these estimates or we adjust these estimates in future periods we may need to adjust our valuation allowance which could materially impact our financial position and results of operations.

Results of Operations



Product Revenue.

Product revenue remained flat at $30.8 million. Power Systems was down 1% from $20.2 million in 2001 to $19.9 million in 2002. This was
offset by an increase in the Electronics Division from $10.6 million in 2001 to $10.9 million in 2002.

Within
Power Systems, revenue from magnetic levitation and high performance motor products declined 35% from $7.2 million in 2001 to $4.7 million in 2002. This decrease was
due in large part to the decline in revenue from magnetic levitation products due to the weak semiconductor industry. In addition, revenue from vibration test equipment ("Shaker") was down 39% from
$12.2 million in 2001 to $7.5 million in 2002. This reduction in Shaker revenue was due in part to the disruption caused by the relocation of the business from Anaheim, CA to Worcester,
MA during the last half of 2002. These

29

---

decreases were more than offset by an increase in revenue from power conversion products from $0.8 million in 2001 to $7.7 million in 2002. This increase was due largely to the fact
that Inverpower was acquired in July 2001 and, as a result, represented less than three months of business in 2001. The increase in 2002 was due, in addition to having a full year of business,
to the up tick in the power conversion products.

Despite
the weak telecom and semiconductor industries, the Electronics Division was able to increase revenue by 3% from $10.6 million in 2001 to $10.9 million in 2002. The
increase was due to an increase in revenue from the defense sector, which during 2002 represented approximately 69% of the total Electronics Division revenue. This compared with approximately 63% in
2001. In addition, on September 27, 2002, we acquired the hybrid product line from Sipex Corp. and were able to ship $0.2 million of product during 2002.

Funded research and development and other revenue.

Funded research and development and other revenue decreased by $0.1 million, or 1% from $10.9 million to $10.8 million. The largest change
was the increase of $1.7 million in funded research and development revenue from a program to develop high power converter assemblies for the U.S. Navy's next generation of modern
"all-electric" ships offset by decreases of $0.6 million from a Department of Energy program to develop low-cost power conversion modules for electric and
hybrid-electric vehicles and $0.6 million from the U.S. Navy's electric missile air launch system program.

Cost of product revenue.

Cost of product revenue increased by $1.8 million, or 7%, from $27.8 million to $29.6 million. The increase was attributable to
$3.8 million of increased cost of product revenue from Power Systems from $17.6 million to $21.4 million. This increase was offset in part by a decrease in the Electronics
Division of $2.0 million from $10.1 million in 2001 to $8.1 million in 2002.

Within
Power Systems, power products accounted for $6.1 million of the increase due primarily to the full year effect of the Inverpower acquisition. This increase was offset by a
decrease of $2.3 million in the Shaker, magnetic levitation and high performance motors cost of product revenue, which all experienced volume reductions in 2002. Inventory obsolescence charges
for Power Systems products totaled $1.9 million in 2002 compared with $0.2 million in 2001. These charges in 2002 represented $1.0 million in power conversion products,
$0.6 million in Shakers and $0.3 million in other products.

The
Electronics Division was able to realize a decrease in its cost of product revenue despite a 3% increase in revenue. This decrease was primarily due to lower spending resulting from
its restructuring program, and, to a lesser extent, lower material costs as a percentage of revenue. Charges for inventory obsolescence were $0.4 million in each year.

Funded research and development and other revenue expenses.

Funded research and development and other revenue expenses decreased by $0.3 million, or 4%, from $7.4 million in 2001 to $7.2 million in
2002. The largest change was the increase of $1.2 million in funded research and development revenue expenses from a program to develop high power converter assemblies for the U.S. Navy's next
generation of modern "all-electric" ships offset by a decrease of $0.4 million from the U.S. Navy's electric missile air launch system program. In addition, we provided an
additional provision of $0.1 million for contract losses during 2002. Although revenue from the Department of Energy program to develop low-cost power conversion modules for
electric and hybrid-
electric vehicles decreased by $0.6 million, there was no corresponding reduction in costs as that revenue was derived from costs incurred in 2000.

30

---

Unfunded research and development expenses.

Unfunded research and development expenses decreased by $0.4 million, or 6%, from $6.2 million in 2001 to $5.9 million in 2002. The decrease
is due to the near completion of the internally funded research and development projects including the power inverter for an on-site power generation system and our 250 kilowatt and 2.2
megawatt rotary UPS and power quality systems.

Selling, general and administrative expenses.

Selling, general and administrative expenses increased by $2.3 million, or 17%, from $13.6 million in 2001 to $15.9 million in 2002. The
increase was primarily due to the full-year inclusion of Inverpower for 2002 and to a lesser extent the increase in business development costs, primarily in the Applied Technology
Division.

Write-off of public offering costs.

On April 25, 2001, we converted our registration statement initially filed with the Securities and Exchange Commission on October 30, 2000 to a
shelf registration statement. We expensed during 2001 $1.4 million of equity financing costs incurred in connection with this initial registration statement.

Amortization of goodwill and intangibles.

Amortization of goodwill and intangibles decreased by $774,000, or 57%, from $1.4 million in 2001 to $0.6 million in 2002. The decrease is a result
of the adoption of SFAS No. 142,Goodwill and Other Intangible Assets, and of no longer being required to amortize goodwill and intangible assets
with indeterminable lives. During the year ended September 30, 2001, amortization of goodwill amounted to $0.6 million. In addition, during 2001 we wrote-off an impaired
intangible asset with a net book value of $0.1 million and annual amortization of $0.1 million. These decreases were partially offset by the amortization of intangible assets acquired
from Inverpower in July 2001.

Restructuring costs.

During April 2002, we commenced a restructuring plan designed to streamline our production base, improve efficiency and enhance our competitiveness and
recorded a restructuring charge of $1.5 million. The restructuring charge includes approximately $0.6 million for severance costs associated with the reduction of approximately 60
employees, or 17% of the work force. The reductions occurred in the following business segments: Applied Technology9: Corporate2; Electronics16; and Power
Systems33. On a functional basis, the reductions were: manufacturing45; research and development4; and selling, general and administrative11. As of
September 30, 2002, 56 employees have been terminated and the remaining 4 are expected to be terminated by March 2003. In addition, as of September 30, 2002, $0.5 of the severance
has been paid and the remaining severance will be paid by March 2003. The balance of the restructuring charge relates to the closing of the Anaheim, CA facility. These costs include
approximately $0.3 million of cash charges primarily related to rent, real estate taxes and operating costs to be paid through the remainder of the lease and an estimated $0.3 million of
other cash charges for restoration and clean-up. In addition, approximately $0.2 million of the restructuring charge relates to non-cash charges on assets to be disposed
of. We anticipate the Anaheim, CA manufacturing facility will be closed during the second quarter of fiscal year 2003.

Net unrealized loss on warrants to purchase common stock.

Net unrealized loss on warrants to purchase common stock decreased by $1.0 million, or 65%, from $1.5 million in 2001 to $0.5 million in
2002. We account for our warrants to purchase Mechanical Technology Incorporated's common stock and to purchase Beacon Power's common stock in accordance with SFAS No. 133, Accounting for Derivative Instruments and
Hedging Activities, and, therefore, we have

31

---

recorded these warrants at their fair value at September 30, 2002 and recorded and unrealized loss of $0.5 million during 2002.

Write-down of investment in Beacon Power Corporation.

Effective September 28, 2001, we account for our investment in Beacon Power using the fair value method as set forth in SFAS No. 115, Accounting for
Certain Debt and Equity Securities. At September 30, 2002, the fair market value of Beacon Power's common stock was $0.17 per
share. Our cost basis in our investment in Beacon Power's common stock was $0.59 per share. As of September 30, 2002, we believe the decline in market value represents an other than temporary
decline because, among other things, the market value has been less than cost since March 2002 and there is some uncertainty of the financial condition and near-term prospects of Beacon Power and,
accordingly, we have recorded an other than temporary write-down of our investment in Beacon Power of $1.4 million.

Other income.

Other income decreased by $0.5 million, or 79%, from $0.6 million in 2001 to $0.1 million in 2002. The decrease is primarily the result of
$0.4 million decrease in interest income, which is directly related to the decrease in cash, cash equivalents and marketable securities.

Loss from Beacon Power Corporation.

Effective September 28, 2001, we account for our investment in Beacon Power using the fair value method as set forth in SFAS No. 115, Accounting for
Certain Debt and Equity Securities. We are no longer required to record our share of any losses from Beacon Power and the investment is
carried at fair value and is designated as available for sale, and any unrealized holding gains and losses are to be included in stockholders' equity as a component of accumulated other comprehensive
income (loss).

Cumulative effect of change in accounting principle.

On October 1, 2000, we began accounting for our warrants to purchase Mechanical Technology Incorporated common stock in accordance with SFAS No. 133
and, therefore, recorded a cumulative unrealized loss of $1.0 million as of October 1, 2000. On June 30, 2001, we began accounting for warrants to purchase our common stock that
are designated as a liability in accordance with EITF 00-19, "Accounting for Derivative Financial Instruments Indexed to, and Potentially Settled in, a Company's
Own Stock", and, therefore, recorded a cumulative unrealized gain of $1.0 million as of June 30, 2001 to record the warrants at fair value.



Product Revenue.

Product revenue increased by $8.4 million, or 37%, from $22.4 million in 2000 to $30.8 million in 2001. The increase was attributable to
$6.1 million of increased revenue from Power Systems, of which Ling Electronics accounted for $4.9 million, magnetic levitation products and high-performance motors accounted
for $0.7 million and power products accounted for $0.5 million, primarily as a result of our acquisition of Inverpower. $2.3 million of increased revenue was attributable to the
Electronics Division.

Funded research and development and other revenue.

Funded research and development and other revenue increased by $2.3 million, or 26%, from $8.6 million in 2000 to $10.9 million in 2001. This
increase was primarily attributable to $2.7 million in funded research and development revenue from a new program to develop high power converter

32

---

assemblies for the U.S. Navy's next generation of modern "all-electric" ships offset by a reduction of $0.4 million in funded research and development revenue from a Department of
Energy program to develop low-cost power conversion modules for electric and hybrid-electric vehicles.

Cost of product revenue.

Cost of product revenue increased by $8.8 million, or 46%, from $19.1 million in 2000 to $27.8 million in 2001. The increase was primarily
attributable to the increase in product revenue. In addition, for 2001, we provided a $1.2 million reserve for excess and obsolete inventory as compared to $0.7 million for 2000. Gross
margin from product revenue as a percentage of product revenue decreased from 15% in 2000 to 10% in 2001.

Funded research and development and other revenue expenses.

Funded research and development and other revenue expenses increased by $598,000, or 9%,from $6.8 million
in 2000 to $7.4 million in 2001. The increase was primarily attributable to $1.9 million in funded research and development expenses from the U.S. Navy program offset by the reduction of
$1.0 million of research and development expenses related to the Department of Energy program.

Unfunded research and development expenses.

Unfunded research and development expenses increased by $2.8 million, or 80%, from $3.5 million in 2000 to $6.2 million in 2001. The increase
is due to increased focus on internally funded research and development projects including the power inverter for an on-site power generation system and our 250 kilowatt and 2.2 megawatt
rotary UPS and power quality systems.

Selling, general and administrative expenses.

Selling, general and administrative expenses increased by $3.6 million, or 36%, from $10.0 million in 2000 to $13.6 million in 2001. The
increase was primarily due to an increase in selling expenses associated with the $10.6 million increase in total revenue and the inclusion of Ling Electronics for the entire fiscal year 2001
and Inverpower from July 13, 2001 to September 30, 2001. During 2001, we provided a $0.5 million reserve for doubtful accounts as compared to $0.3 million in 2000. In
addition, we recorded charges of $0.2 million, $0.2 million, $0.2 million and $0.1 million in settlement of litigation, consolidation of facilities, write-off
of impaired assets and for acceleration of a stock option award-vesting schedule, respectively, during 2001.

Write-off of public offering costs.

On April 25, 2001, we converted our registration statement initially filed with the Securities and Exchange Commission on October 30, 2000 to a
shelf registration statement. We expensed $1.4 million of equity financing costs incurred in connection with this initial registration statement.

Amortization of intangibles.

Amortization of intangibles increased by $0.1 million, or 12%, from $1.2 million to $1.4 million. The increase was the result of amortization
of intangibles recorded in connection with the acquisitions of Ling Electronics in October 1999, certain intellectual property and other intangible assets from Northrop Grumman in
November 1999 and certain intangible assets from Inverpower Controls Ltd. in July 2001. In addition, during 2001 we wrote-off an impaired intangible asset with a net
book value of $0.1 million.

Net unrealized loss on warrants to purchase common stock.

During the fiscal year ended September 30, 2001, we began accounting for our warrants to purchase Mechanical Technology Incorporated's common stock and the
warrant to purchase Beacon Power's common stock in accordance with SFAS No. 133, and, therefore, we have recorded these warrants at their fair value at September 30, 2001 and recorded an
unrealized loss of $1.5 million during 2001.

Other income (loss).

Other income increased $0.1 million, or 27%, from $0.5 million in 2000 to $0.6 million in 2001. The increase is the result of cash, cash
equivalents and marketable securities being maintained in interest bearing accounts offset by an increase in interest expense associated with the increase in debt.

Loss from Beacon Power Corporation.

Loss from Beacon Power Corporation increased by $4.2 million from $0.9 million in 2000 to $5.1 million in 2001. In connection with Beacon
Power's initial public offering in November 2000, our investment in Beacon Power and additional paid-in-capital was written up to reflect our beneficial interest in the
book value of the stockholders' equity of Beacon Power, which was approximately $16.6 million, less losses previously recorded in connection with the put right obligation in the amount of
$5.8 million for a net gain of $10.7 million. After the write-up of our investment in Beacon Power, we continued to account for our investment in Beacon Power under the
equity method of accounting and recorded our share of losses of $5.1 million from Beacon Power for 2001.

Cumulative effect of change in accounting principle.

On October 1, 2000, we began accounting for our warrants to purchase Mechanical Technology Incorporated common stock in accordance with SFAS No. 133
and, therefore, recorded a cumulative unrealized loss of $1.0 million as of October 1, 2000. On June 30, 2001, we began accounting for warrants to purchase our common stock that
are designated as a liability in accordance with EITF 00-19,Accounting for Derivative Financial Instruments Indexed to, and Potentially Settled in, a
Company's Own Stock, and, therefore, recorded a cumulative unrealized gain of $0.9 million as of June 30, 2001 to record the warrants at fair value.

Quarterly Results of Operations

The following table presents unaudited quarterly statement of operations data for the eight quarters ended September 30, 2002. This data has been prepared
on a basis consistent with our audited consolidated financial statements included elsewhere in this Annual Report on Form 10-K. This data includes all adjustments, consisting solely
of normal recurring adjustments, that we believe necessary for a fair presentation of this information. The operating results for any quarter are not necessarily indicative of results to be expected
for any future period. In fiscal year 2002, we changed the reporting periods for operational purposes for the first three quarters of our fiscal year to the 13-week periods ending on the
last Saturday of the last month of each quarter. We believe that due to this fact there is no material difference between the 2002 and 2001 quarterly statement of operations data and that the results
of all periods presented are comparable.

The
fourth quarter of 2002 includes a provision of $1.3 million for excess and obsolete inventory as compared to $0.2 million during the fourth quarter of 2001. The fourth
quarter of 2002 provision includes $0.8 million for inventory related to residential fuel cell and battery UPS products. Based on our strategic business plan to focus our efforts on our rotary
UPS systems, we deemed it appropriate during the fourth quarter to establish these reserves.

Liquidity and Capital Resources

We need an immediate infusion of equity capital to sustain our operations. We anticipate that our existing cash and cash resources will enable us to fund our
operations through only approximately January 15, 2003. As more fully discussed below, if Silicon Valley Bank, our senior lender, decides to discontinue lending to us, which it has the right to
do, or we are unable to raise additional equity by
January 15, 2003, we will be forced to furlough or permanently lay off a significant portion of our work force which will have a material adverse impact on us. Under these circumstances, we may
not be able

35

---

to continue our operations. Further, without additional cash resources, we may not be able to keep all or significant portions of our operations going for a sufficient period of time to enable us to
sell all or portions of our assets or operations at other than distressed sale prices.

We
have incurred significant costs to develop our technologies and products. These costs have exceeded total revenue. As a result, we have incurred losses in each of the past five years.
As of September 30, 2002, we had an accumulated deficit of $85.2 million. During the fiscal year ended September 30, 2002, we incurred a loss of $20.8 million and a
reduction in our cash from $20.9 million to $2.1 million. Due to restructuring activities, we were able to slow our cash burn rate from $7.9 million in the first quarter of fiscal
year 2002 to $5.2 million, $3.5 million and $2.1 million in the second, third and fourth quarters of fiscal year 2002, respectively.

However,
we need to achieve quarterly revenue of approximately $15 million in order to reach a breakeven cash run rate based on today's cost structure and expected incremental margins on
the additional revenue. Our highest quarterly revenue for fiscal year 2002 were $11.7 million in the third quarter of fiscal year 2002. Given our current operating plan, we do not expect to
achieve $15 million of quarterly revenue until the fourth quarter of fiscal year 2003 at the earliest. As a result, because we had only $2.1 million in cash at the end of fiscal year
2002, we will need at least $9 million to $10 million in borrowing capacity and additional capital, in the aggregate, in order to fund our current business plan for the next
12 months. We may also need additional future funds in order to fund unanticipated operating losses, to grow, to develop new or enhance existing products and services and to respond to
competitive pressures.

At
September 30, 2002, we had a line of credit with Silicon Valley Bank which enabled us to borrow up to $5 million based on eligible receivables, and none of the credit
line had been used as of that date. The credit line included various financial covenants which needed to be satisfied in order for us to retain our right to borrow. One of these covenants required us
to raise $4 million of new equity or subordinated debt by December 1, 2002. We did not raise these funds as of December 1, 2002 and, as a result, are in default under the credit
line and from December 1, 2002 through December 18, 2002, were not permitted to borrow against the credit line. As of December 1, 2002, the loan balance was $2.1 million
and all receipts from our Electronics and Power Systems divisions were required to be used to reduce this loan. Although Silicon Valley Bank is not required to do so while we are in default under our
loan agreement, it has permitted us to use receivables collected from our Applied Technology division. As a result, from December 1, 2002 through December 18, 2002, we were limited to
available cash and receipts from our Applied Technology division to fund our business until the Silicon Valley Bank loan was repaid. This level of resources is insufficient to sustain our ongoing
operations as our Applied Technology division generates less than $1 million of cash receipts in an average month.

On
December 19, 2002, we entered into a forebearance agreement with Silicon Valley Bank pursuant to which Silicon Valley Bank agreed that, unless other defaults occurred under our
credit facility, Silicon Valley Bank would not exercise its rights as creditor under our loan agreement with them until
January 15, 2003. We hope that Silicon Valley Bank's forbearance will enable us sufficient time to raise $4 million of equity capital or subordinated debt by January 15, 2003. We
acknowledged to Silicon Valley Bank in the forebearance agreement that we were in material default of our credit facility with Silicon Valley Bank. The forebearance agreement required us to obtain a
signed term sheet by December 19, 2002 for a transaction structured to raise at least $3 million and, as more fully described below, we believe we have met this requirement.

On
December 19, 2002, we owed Silicon Valley Bank approximately $886,000 and had a cash balance of approximately $1 million. As a result of executing the forbearance
agreement, we are now able to return to borrowing from the bank, but are limited to the lesser of 75% of eligible receivables or $2 million. In addition, all collections can now be used by us
to fund operations or pay down the loan, as they had been prior to the default on December 1, 2002. Although the line of credit was up to

36

---

$5 million prior to our default, it was limited to 75% of eligible receivables which typically permitted borrowing in the October to November period of from approximately $2.2 million
to $2.8 million outstanding at any one time. However, at anytime prior to January 15, 2003, Silicon Valley Bank may discontinue lending funds to us if, in its business judgment, it
decides to do so.

We
intend to work with Silicon Valley Bank in an effort to amend the existing credit facility before January 15, 2003. The existing credit facility is scheduled to expire in
September, 2003. However, there can be no assurance that we will be successful in achieving an amended credit facility by January 15, 2003. We believe that we will need to raise at least
$3 million of new equity or subordinated debt, acceptable to Silicon Valley Bank, by January 15, 2003, or we will be unable to borrow funds or use new collections to fund our business
after January 15, 2003. If we are unable to raise these additional funds, we may not be able to amend our existing credit facility with Silicon Valley Bank which would permit us to borrow any
additional amounts under the credit facility.

On
December 13, 2002, we executed a term sheet with an institutional investor to raise between $5 and $7 million of equity capital. The term sheet contemplates that $3 to
$5 million of the equity investment will be funded during the week of January 6, 2003 and the remaining $2 million will be funded promptly after the registration statement we are
required to file with the Securities and Exchange Commission is declared effective registering all of the underlying equity securities in this financing. We expect it will take a minimum of
90 days to file a registration statement and obtain its effectiveness. We will be unable to file a registration statement until after we have an initial closing with the
institutional investor. To date, the documentation relating to this financing has been produced by counsel to the institutional investor but has not been finalized. There can be no guarantee that we
will be able to successfully close this financing and raise the $5 to $7 million on the terms contemplated by the term sheet or on any other terms.

We
have agreed with the institutional investor that we will not solicit or negotiate any additional equity or debt financings through January 14, 2003. Upon consummation of a
financing with the institutional investor, the institutional investor would have rights of first refusal and exchange rights which would generally be triggered upon future financings we may seek to
consummate. The right of first refusal would allow the institutional investor to purchase future securities issued by us for a period of
12 months following the initial closing of the financing. For a period of 24 months following the initial closing, the exchange right would allow the institutional investor to exchange
any shares of preferred stock held by it into future securities that we may issue at the preferred stock's liquidation preference. Each of these factors may adversely affect our ability to raise
additional funds from third parties on terms acceptable to us, or at all.

The
financing with the institutional investor would also require that we seek the approval of our stockholders, which we will attempt to obtain at our 2003 annual meeting of
stockholders. In the event that we do not obtain the approval of our stockholders, we would be required to redeem all or a portion of the investment by the institutional investor in cash, which would
have a material adverse effect on us and our operations. The exercise by the institutional investor of any rights of first refusal or exchange rights may require us to seek additional approvals of our
stockholders, which may not be required if these rights were not exercised. This may also hinder or delay our ability to obtain equity funding in the future.

Any
securities offered to the institutional investor will not be or have not been registered under the Securities Act of 1933 and may not be offered or sold in the United States absent
registration or an applicable exemption from the registration requirements.

If
Silicon Valley Bank does not continue to lend money to us through January 15, 2003 or we are unable to close an equity financing with the institutional investor prior to
January 15, 2003, we will be forced to furlough or permanently lay off a significant portion of our work force. This will have a material adverse effect on us. Under these circumstances, we may
not be able to continue our operations. Further, without additional cash resources, we may not be able to keep all or a significant

37

---

portion of our operations going for a sufficient period of time to enable us to sell all or portions of our assets or operations at other than distressed sale prices.

Our
financial statements for our fiscal year ended September 30, 2002, which are included in this Annual Report on Form 10-K, contain an audit report from Grant
Thornton LLP. The audit report contains a going concern qualification which raises substantial doubt with respect to our ability to continue as a going concern. The receipt of a going concern
qualification may adversely affect our ability to manage our accounts payable and cause some of our suppliers to deal with us on a cash-on-delivery basis only. If this were to
occur, this would adversely affect our operations by increasing our immediate need for additional capital.

If
additional funds are raised through the issuance of equity or convertible debt securities, the percentage ownership of our stockholders will be reduced and our stockholders may
experience additional dilution. The terms of additional funding may also limit our operating and financial flexibility. There can be no assurance that additional financing of any kind will be
available to us on terms acceptable to us, or at all. Failure to obtain future funding when needed or on acceptable terms would materially, adversely affect our results of operations.

Since
inception, we have financed our operations and met our capital expenditure requirements primarily through the sale of private equity securities, public security offerings,
borrowings on our expired line of credit and capital equipment leases.

As
of September 30, 2002, our cash, cash equivalents and marketable securities were $2.1 million, a decrease of $18.8 million from September 30, 2001. Cash
used in operating activities for the fiscal year ended September 30, 2002 was $15.3 million as compared to $11.0 million in 2001. Cash used in operating activities during the
fiscal year ended September 30, 2002 was primarily attributable to our net loss offset by non-cash items such as depreciation and amortization, increases in allowances for
uncollectible accounts and excess and obsolete inventory, realized gain on sale of marketable securities, net unrealized loss from warrants to purchase common stock, write-off of impaired
assets, write-down of investment in Beacon Power Corporation, non-cash compensation expense and changes in working capital.

Cash
used in investing activities during the fiscal year ended September 30, 2002 was $3.1 million, excluding the sale of marketable securities of $9.9 million, as
compared to $2.0 million excluding the purchase of marketable securities of $9.9 million, in 2001. Net cash used in investing activities during the fiscal year ended September 30,
2002 included capital expenditures of $3.1 million primarily at Power Systems to expand our capacity to manufacture our power conversion products.

Cash
used in financing activities for the fiscal year ended September 30, 2002 was $0.3 million as compared to $25.1 million provided by financing activities in
2001. Net cash used by financing activities during the fiscal year ended September 30, 2002 represents the repayment of long-term debt.

Factors Affecting Future Results

Our future results remain difficult to predict and may be affected by a number of factors which could cause actual results to differ materially from
forward-looking statements contained in this Annual Report on Form 10-K and presented elsewhere by management from time to time. These factors include business conditions within the
distributed power, power quality, aerospace, transportation, industrial, utility, telecommunications, silicon wafer manufacturing, factory automation, aircraft and automotive industries and the world
economies as a whole, and competitive pressures that may impact research and development spending. Our revenue growth is dependent on technology developments and contract research and development for
both the government and commercial sectors and no assurance can be given that these investments will continue or that we will be able to obtain such funds. In addition, our growth opportunities are
dependent on the introduction of new products that must penetrate distributed power, power quality, aerospace, transportation, industrial, utility, telecommunications, silicon wafer manufacturing,
factory automation, aircraft and automotive markets. No assurance can be given that new products can be developed, or if developed, will be successful; that competitors will not force prices to an
unacceptably low level or take market share from us; or that we can achieve or maintain profits in these or any new markets. Because of these and other factors, past financial performance should not
be considered an indicator of future performance. Investors should not use historical trends to anticipate future results and should be aware that the market price of our common stock experiences
significant volatility.

Effects of Inflation

We believe that inflation and changing prices over the past three years have not had a significant impact on our net revenue or on our income from continuing
operations.

Recent Accounting Pronouncements

In August 2001, the Financial Accounting Standards Board (FASB) issued SFAS No. 144,Accounting for the Impairment or
Disposal of Long Lived Assets,which supersedes SFAS No. 121,Accounting for the Impairment of Long-Lived Assets and for
Long-Lived Assets to Be Disposed Of, and the accounting and reporting provisions of APB No. 30. SFAS No. 144 addresses financial accounting and
reporting for the impairment or disposal of long-lived assets and is effective for fiscal years beginning after December 15, 2001, and interim periods within those fiscal years. We
are currently reviewing this statement to determine its effect on our consolidated financial statements.

In
April, 2002, the FASB issued SFAS No. 145,Rescission of FASB Statements No. 4, 44, and 64, Amendment of FASB Statement No. 13, and
Technical Corrections. SFAS No. 145 rescinds SFAS No. 4,Reporting Gains and Losses from Extinguishment of Debt,
and an amendment of that statement, SFAS

39

---

No. 44,Accounting for Intangible Assets of Motor Carriers, and SFAS No. 64,Extinguishment of Debt Made to
Satisfy Sinking-Fund Requirements. This statement amends SFAS No. 13,Accounting for Leases, to eliminate an
inconsistency between the required accounting for sale-leaseback transactions. This statement also amends other existing authoritative pronouncements to make various technical corrections,
clarify meanings, or describe their applicability under changed conditions and is effective for fiscal years beginning after May 15, 2002. We are currently reviewing this statement to determine
its effect on our consolidated financial statements.

In
July 2002, the FASB issued SFAS No. 146,Accounting for Costs Associated with Exit or Disposal Activities. SFAS
No. 146 addresses financial accounting and reporting for costs associated with exit or disposal activities and nullifies Emerging Issues Task Force (EITF) Issue No. 94-3, Liability Recognition for Certain Employee
Termination Benefits and Other Costs to Exit an Activity (including Certain Costs Incurred in a
Restructuring). This statement is effective for exit and disposal activities initiated after December 31, 2002. We are currently reviewing this statement to determine
its effect on our consolidated financial statements.

In
November 2001, the EITF issued Topic No. D-103 (Topic D-103) relating to the accounting for reimbursements received for
out-of-pocket expenses. In accordance with Topic D-103, reimbursements received for out-of-pocket expenses incurred should be characterized
as revenue in the statement of operations. Our arrangements have historically included reimbursement for expenses as part of the
overall fee charged. As a result, we have historically accounted for these reimbursements as revenue and recorded the associated costs as either cost of product revenue or funded research and
development and other revenue expenses. As a result, our adoption of Topic D-103 had no impact on our financial position, results of operations and cash flows.

Item 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

We develop products in the United States and sell them worldwide. As a result, our financial results could be affected by factors such as changes in foreign
exchange rates or weak economic conditions in foreign markets. Since our sales are currently priced in U.S. dollars and are translated to local currency amounts, a strengthening of the dollar could
make our products less competitive in foreign markets. Interest income is sensitive to changes in the general level of U.S. interest rates, particularly since our investments are in
short-term instruments. Based on the nature and current levels of our investments, however, we have concluded that there is no material market risk exposure.

REPORT OF INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS

To
the Board of Directors of
SatCon Technology Corporation:

We
have audited the accompanying consolidated balance sheet of SatCon Technology Corporation and its subsidiaries (the Company) (a Delaware corporation) as of September 30, 2002
and the related consolidated statements of operations, changes in stockholders' equity and comprehensive loss and cash flows for the year then ended. These consolidated financial statements are the
responsibility of the Company's management. Our responsibility is to express an opinion on these consolidated financial statements based on our audit. The consolidated financial statements of SatCon
Technology Corporation as of September 30, 2001 and for the two years then ended were audited by other auditors who have ceased operations. Those auditors expressed an unqualified opinion on
those consolidated financial statements in their report dated December 4, 2001.

We
conducted our audit in accordance with auditing standards generally accepted in the United States of America. Those standards 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. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.

In
our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the consolidated financial position of SatCon Technology Corporation and
its subsidiaries as of September 30, 2002 and the results of their operations and their cash flows for the year then ended in conformity with accounting principles generally accepted in the
United States of America.

The
accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Note B to the financial
statements, the Company
incurred a net loss of $20,760,598 during the year ended September 30, 2002, and, as of that date, the Company used $15,339,425 in its operating activities. The Company is operating under a
forbearance agreement with its primary lender in which, unless other defaults occur, the primary lender would not exercise its rights as a creditor under the loan agreement until January 15,
2003. The Company needs an infusion of equity capital and, in addition, needs to achieve quarterly revenues at levels it has not achieved in the recent past in order to reach an estimated breakeven
cash run rate. These factors, among others, as discussed in Note B to the financial statements, raise substantial doubt about the Company's ability to continue as a going concern. Management's
plan in regards to these matters are also described in Note B. The financial statements do not include any adjustments that might result from the outcome of this uncertainty.

As
discussed above, the consolidated financial statements of the Company as of September 30, 2001 and 2000, and for the years then ended were audited by other auditors who have
ceased operations. As described in Note C, these consolidated financial statements have been revised to include the transitional disclosures required by Statement of Financial Accounting
Standards No. 142,Goodwill and Other Intangible Assets(SFAS No. 142) which was adopted by the Company as of October 1, 2001. Our
audit procedures with respect to the disclosures in Note C for fiscal 2001 and 2000 included (i) agreeing the previously reported net loss attributable to common stockholders before
cumulative effect of changes in accounting principles ("net loss") to the previously issued consolidated financial statements and the adjustments to reported net loss representing amortization expense
(including any related tax effects) recognized in those periods related to goodwill that are no longer being amortized to the Company's underlying records obtained from management, and
(ii) testing the

mathematical accuracy of the reconciliation of adjusted net loss to reported net loss, and the related loss per weighted average share amounts. In our opinion, the disclosures for fiscal 2001 and
2000 in Note C related to the transitional disclosures of SFAS No. 142 are appropriate. However, we were not engaged to audit, review, or apply any procedures to the Company's
consolidated financial statements for fiscal 2001 and 2000 other than with respect to such disclosures and, accordingly, we do not express an opinion or any other form of assurance on the Company's
fiscal 2001 and 2000 consolidated financial statements taken as a whole.

REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To
the Board of Directors of
SatCon Technology Corporation:

We
have audited the accompanying consolidated balance sheets of SatCon Technology Corporation and its subsidiaries (the Company) (a Delaware corporation) as of September 30, 2001
and 2000 and the related consolidated statements of operations, changes in stockholders' equity and comprehensive loss and cash flows for each of the three years in the period ended
September 30, 2001. 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 in accordance with auditing standards generally accepted in the United States. Those standards 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. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe
that our audits provide a reasonable basis for our opinion.

In
our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of SatCon Technology Corporation and its subsidiaries as of
September 30, 2001 and 2000 and the results of their operations and their cash flows for each of the three years in the period ended September 30, 2001 in conformity with auditing
standards generally accepted in the United States.

SATCON TECHNOLOGY CORPORATION    NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

A.    ORGANIZATION AND BASIS OF PRESENTATION

Organization

SatCon Technology Corporation (the "Company" or "SatCon") was organized as a Massachusetts corporation in February 1985 and reincorporated in Delaware in 1992.
SatCon is developing enabling technologies for the emerging critical power marketplace where power quality and uninterruptible power are important. SatCon designs, develops and manufactures
high-efficiency high power electronics and a variety of standard and custom high-performance machines for specific applications. SatCon's critical power products convert, store
and manage electricity for businesses and consumers, the U.S Government and military that require high-quality, uninterruptible power. SatCon is utilizing its engineering and manufacturing
expertise to develop products that it believes will be integral components of distributed power generation and power quality systems. SatCon's specialty motors are typically designed and manufactured
for unique customer requirements such as high power-to-size requirements or high efficiency.

SatCon
has expanded its business and capabilities through the following acquisitions:



All
of these acquisitions were accounted for using the purchase method of accounting. In addition, in November 1999, the Company acquired intellectual property, tooling and other
assets from Northrop Grumman Corporation and in September 2002, the Company acquired certain intellectual property, equipment and other assets from Sipex Corporation. See Note R.

Basis of Consolidation

The consolidated financial statements include the accounts of SatCon and its majority-owned subsidiaries. All intercompany accounts and transactions have been
eliminated in consolidation.

B.    REALIZATION OF ASSETS AND LIQUIDITY

The
accompanying consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America, which contemplates
continuation of the Company as a going concern. However, the Company has sustained substantial

50

---

losses from operations in recent years. In addition, the Company has used, rather than provided, cash in its operations.

The
Company needs an infusion of equity capital to sustain its operations. The Company anticipates that its existing cash and cash resources will enable it to fund its operations through
only approximately January 15, 2003. As more fully discussed below, if Silicon Valley Bank, the Company's senior lender, decides to discontinue lending, which it has the right to do, or the
Company is unable to raise additional equity by January 15, 2003, it will be forced to furlough or permanently lay off a significant portion of its work force which will have a material adverse
impact. Under these circumstances, the Company may not be able to continue its operations. Further, without additional cash resources, the Company may not be able to keep all or significant portions
of its operations going for a sufficient period of time to enable it to sell all or portions of its assets or operations at other than distressed sale prices.

The
Company has incurred significant costs to develop its technologies and products. These costs have exceeded total revenue. As a result, the Company has incurred losses in each of the
past five years. As of September 30, 2002, it had accumulated deficit of $85.2 million. During the fiscal year ended September 30, 2002, the Company incurred a loss of $20.8
million and a reduction in is cash from $20.9 million to $2.1 million.

However,
even with a reduced cost structure, the Company needs to achieve levels of quarterly revenue, which it has failed to achieve in the past, in order to reach an estimated
breakeven cash run rate. Assuming the Company can execute its current operating plan, it does not expect to achieve a breakeven cash run rate until the fourth quarter of fiscal year 2003 at the
earliest. As a result, because the Company had only $2.1 million in cash at the end of fiscal 2002, it will need significant borrowing capacity and additional capital, in the aggregate, in
order to fund its current business plan for the next 12 months. It may also need additional future funds in order to fund unanticipated operating losses, to grow, to develop new or existing products
and services and to respond to competitive pressures.

During
December 2002, the Company became in default, as defined, of its Loan and Security Agreement, dated September 13, 2002 (the "Loan Agreement"). As of
September 30, 2002, no amount was payable under the Loan Agreement. As of December 19, 2002, $885,527 was outstanding. On December 19, 2002, the Company entered into a Forbearance
Agreement under which the Loan Agreement was extended until January 15, 2003, subject to certain terms and conditions, as defined.

In
view of the matters described in the preceding paragraph, recoverability of a major portion of the recorded asset amounts shown in the accompanying consolidated balance sheet is
dependent upon the continued operations of the Company, which in turn is dependent upon the Company's ability to meet its financing requirements, on a continuing basis, including raising permanent
equity, to maintain present financing, and to succeed in its future operations. The consolidated financial statements do not include any adjustments relating to the recoverability and classification
of recorded asset amounts or
amounts and classification of liabilities that might be necessary should the Company be unable to continue in existence.

Management
of the Company intends to take the following steps to revise its operating and financial requirements, which it believes are sufficient to provide the Company with the ability
to continue its existence:



51

---



However,
there can be no assurance that the Company will be successful in consummating the equity transaction with the institutional investor on schedule and the amount planned and
amending its Loan Agreement with the Bank on schedule with acceptable terms. If both of these transactions are not completed with terms and the timetable envisioned, the Company will likely be forced
to furlough or permanently lay off a significant portion of its workforce which will have a material adverse effect on its financial position and results of operations. Further, without additional
cash resources, the Company, may not be able to keep all or significant portions of its operations going for a sufficient period of time to enable it to sell all or a portion of its assets or
operations at other than distressed sale prices.

C.    SIGNIFICANT ACCOUNTING POLICIES

Revenue Recognition

The Company recognizes revenue from product sales in accordance with Staff Accounting Bulletin (SAB) No. 101,Revenue
Recognition. Product revenue is recognized when there is persuasive evidence of an arrangement, the fee is fixed or determinable, delivery of the product to the customer has
occurred and the Company has determined that collection of the fee is probable. Title to the product generally passes upon shipment of the product, as the products are shipped FOB shipping point
except for certain foreign shipments. If the product requires installation to be performed by the Company, all revenue related to the product is deferred and recognized upon the completion of the
installation. The Company provides for a warranty reserve at the time the product revenue is recognized.

The
Company performs funded research and development and product development for commercial companies and government agencies under both cost reimbursement and fixed-price contracts.
Product development revenue is included in product revenue. Cost reimbursement contracts provide for the reimbursement of allowable costs and, in some situations, the payment of a fee. These contracts
may contain incentive clauses providing for increases or decreases in the fees depending on how costs compare with a budget. On fixed-price contracts, revenue is generally recognized on the percentage
of completion method based upon the proportion of costs incurred to the total estimated costs for the contract. Revenue from reimbursement contracts is recognized as the services are performed. In
each type of contract, the Company receives periodic progress payments or payments upon reaching interim milestones. All payments to the Company for work performed on contracts with agencies of the
U.S. government are subject to audit and adjustment by the Defense Contract Audit Agency. Adjustments are recognized in the period made. When the current estimates of total contract revenue for
commercial product development contracts indicate a loss, a provision for the entire loss on the contract is recorded. Any losses incurred in performing funded research and development projects are
recognized as research and development expense as incurred. As of September 30, 2002 and 2001, the Company has accrued $150,000 and $75,000, respectively, for anticipated contract losses on
commercial contracts. For the fiscal years ended September 30, 2002, 2001 and 2000, revenue from commercial contracts, which represents other revenue, is included in funded research and
development and other revenue and amounted to $203,254, $662,614 and $763,023, respectively.

Cost
of product revenue includes cost of product revenue including material, labor and overhead. Costs incurred in connection with funded research and development and other revenue
arrangements are included in research and development and other revenue expenses. For the fiscal years ended September 30, 2002, 2001 and 2000, costs and expenses from commercial contracts,
which represents other revenue expenses, are included in funded research and development and other revenue expenses and amounted to $182,406, $484,982 and $397,527, respectively.

52

---

Deferred
revenue consists of payments received from customers in advance of services performed, product shipped or installation completed.

Cash and Cash Equivalents

Cash and cash equivalents include demand deposits and highly liquid investments with maturities of three months or less when acquired. Cash equivalents are stated
at cost, which approximates market value.

Marketable Securities

The Company accounts for marketable securities in accordance with Statement of Financial Accounting Standards (SFAS) No. 115, Accounting for Certain
Investments in Debt and Equity Securities. In accordance with SFAS No. 115, investments are classified as held to
maturity, available for sale or trading.

Management
determines the appropriate classification of its investments in marketable securities at the time of purchase and re-evaluates such determination at each balance
sheet date. Debt securities for which the Company does not have the intent or ability to hold to maturity are classified as available for sale.

Securities
available for sale are carried at fair value, based on quoted market prices, with the unrealized gains and losses, net of tax, reported in a separate component of
stockholders' equity except for unrealized losses determined to be permanent in nature. Such unrealized losses are included in the determination of net income in the period in which management
determines the decline to be permanent. The Company is not actively involved in the purchase and sale of investments classified as trading. At September 30, 2002, the Company had no investments
that qualified as trading or held to maturity.

The
amortized cost of debt securities classified as available for sale is adjusted for amortization of premiums and accretion of discounts to maturity. Such amortization and interest are
included in interest income. Realized gains and losses are included in other income or loss. The cost of securities sold is based on the specific identification method.

Inventory

Inventories are stated at the lower of cost or market and costs are determined based on the first-in, first-out method of accounting and
include material, labor and manufacturing overhead costs.

Property and Equipment

Property and equipment are stated at cost. Depreciation and amortization is computed using the straight-line method over the asset's estimated useful
life. The estimated useful lives of property and equipment are as follows:

Estimated LivesComputer equipment and software

35 yearsElectronic laboratory and shop equipment

5 yearsMechanical laboratory and shop equipment

10 yearsSales and demonstration equipment

310 yearsFurniture and fixtures

710 yearsLeasehold improvements

Lesser of the life of the lease or the useful life of the improvement


53

---

When
assets are retired or otherwise disposed of, the cost and related depreciation and amortization are eliminated from the accounts and any resulting gain or loss is reflected in other
income.

Long-lived Assets

Effective October 1, 2001, the Company adopted the provisions of SFAS No. 142,Goodwill and Other Intangible
Assets. This statement affects the Company's treatment of goodwill and other intangible assets. The statements require that goodwill existing at the date of adoption be
reviewed for possible impairment and that impairment tests be periodically repeated, with impaired assets written down to fair value. Additionally, existing goodwill and intangible assets must be
assessed and classified within the statement's criteria. Intangible assets with finite useful lives will continue to be amortized over those periods. Amortization of goodwill and intangible assets
with indeterminable lives will cease.

The
Company completed the first step of the transitional goodwill impairment test during the three months ended March 30, 2002 based on the amount of goodwill as of the beginning
of fiscal year 2002, as required by SFAS No. 142. The Company utilized a third party independent valuation to determine the fair value of each of the reporting units based on a discounted cash
flow income approach. The income approach indicates the fair value of a business enterprise based on the discounted value of the cash flows that the business can be expected to generate in the future.
This analysis is based upon projections prepared by the Company and data from sources of publicly available information available at the time of preparation. There will usually be differences between
estimated and actual results as events and circumstances frequently do not occur as expected, and those differences may be material. Based on the results of the first step of the transitional goodwill
impairment test, the Company has determined that the fair value of each of the reporting units exceeded their carrying amounts and, therefore, no goodwill impairment existed as of October 1,
2001. As a result, the second step of the transitional goodwill impairment test was not required to be completed. The Company performed a goodwill impairment test as of the beginning of its fiscal
fourth quarter 2002, as required by SFAS No. 142 on an annual basis. The Company again utilized a third party independent valuation to determine the fair value of each of the reporting units
based on a discounted cash flow income approach. Based on the results of the first step of the annual goodwill impairment test, the Company has determined that the fair value of each of the reporting
units exceeded their carrying amounts and, therefore, no goodwill impairment existed as of the beginning of its fiscal fourth quarter 2002. As a result, the second step of the annual goodwill
impairment test was not required to be completed. The Company will continue to perform a goodwill impairment test on an annual basis.

The
Company did not record expense related to the amortization of goodwill during the fiscal year ended September 30, 2002. The Company recorded expense related to the
amortization of goodwill of $638,864 during the fiscal year ended September 30, 2001. The Company has determined that all of its intangible assets have finite lives and, therefore, the Company
has continued to amortize its intangible assets. The Company recorded expense related to the amortization of its intangible assets of $618,118 and $674,732 during the fiscal year ended
September 30, 2002 and 2001, respectively.

Foreign Currency Translation

The functional currency of the Company's foreign subsidiary is the local currency. Assets and liabilities of foreign subsidiaries are translated at the rates in
effect at the balance sheet date, while stockholders' equity (deficit) is translated at historical rates. Statements of operations and cash flow amounts are translated at the average rate for the
period. Translation adjustments are included as a component of accumulated other comprehensive loss. Foreign currency gains and losses arising from transactions are reflected in the loss from
operations and were not significant during the fiscal years ended September 30, 2002, 2001 and 2000.

Treasury Stock

The Company was authorized to repurchase up to 5% of the Company's outstanding shares of common stock through July 2000. Under the repurchase program, the
Company purchased 44,500 shares of the Company's outstanding common stock at a cost of $249,704. During the fiscal year ended September 30, 2001, the Company retired the 44,500 shares purchased
under the repurchase program.

Use of Estimates

The preparation of financial statements, in conformity with accounting principles generally accepted in the United States, 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 financial statements and the reported amounts of
revenue and expenses during the period reported. Actual results could differ from these estimates.

Income Taxes

The Company accounts for income taxes in accordance with SFAS No. 109,Accounting for Income Taxes, which
is the asset and liability method for accounting and reporting for income taxes. Under SFAS No. 109, deferred tax assets and deferred tax liabilities are recognized based on temporary
differences
between the financial reporting and income tax basis of assets and liabilities using statutory rates. In addition, SFAS No. 109 requires a valuation allowance against net deferred tax assets
if, based upon the available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized.

Stock-based Compensation

SFAS No. 123,Accounting for Stock-Based Compensation, requires the measurement of the fair value of stock
options or warrants granted to employees to be included in the statement of operations or, alternatively, disclosed in the notes to consolidated financial statements. The Company accounts for
stock-based compensation of employees under the intrinsic value method of Accounting Principles Board (APB) Opinion No. 25,Accounting for Stock Issued to
Employees, and has elected the disclosure-only alternative under SFAS No. 123. The Company records the fair market value of stock options and warrants
granted to non-employees in exchange for services in accordance with Emerging Issues Task Force (EITF) No. 96-18,Accounting for Equity
Instruments That Are Issued to Other Than Employees for Acquiring, or in Conjunction with Selling, Goods or Services, in the consolidated statement of operations.

Net Loss per Basic and Diluted Common Share

The Company reports net loss per basic and diluted common share in accordance with SFAS No. 128,Earnings Per
Share, which establishes standards for computing and presenting earnings per share. Basic earnings per share excludes dilution and is computed by dividing income available to
common stockholders by the weighted-average number of common shares outstanding for the period.

56

---

Diluted earnings per share reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock or resulted in the
issuance of common stock that then shared in the earnings of the Company.

Concentration of Credit Risk

Financial instruments that subject the Company to concentrations of credit risk principally consist of cash equivalents, marketable securities, trade accounts
receivable, unbilled contract costs and amounts receivable from exercise of stock options.

The
Company's trade accounts receivable and unbilled contract costs and fees are primarily from sales to U.S. government agencies and commercial customers. The Company does not require
collateral and has not historically experienced significant credit losses related to receivables or unbilled contract costs
and fees from individual customers or groups of customers in any particular industry or geographic area.

The
Company deposits its cash and invests in short-term investments primarily through a regional commercial bank and an investment company. Credit exposure to any one entity
is limited by Company policy.

Research and Development Costs

The Company expenses research and development costs as incurred. Research and development and other revenue expenses include costs incurred in connection with
both funded research and development and other revenue arrangements and unfunded research and development activities.

Comprehensive Income (Loss)

Comprehensive income (loss) includes net loss, change in unrealized gains and losses on marketable securities, change in unrealized gains and losses on investment
in Beacon Power and foreign currency translation adjustments.

Fair Value of Financial Instruments

The Company's financial instruments consist of cash and cash equivalents, marketable securities, accounts receivable, unbilled contract costs and fees, warrants
to purchase shares of common stock, accounts payable, debt instruments and contingent obligation to Class D preferred stockholders of Beacon Power Corporation. The estimated fair values of
these financial instruments approximate their carrying values at September 30, 2002 and 2001. The estimated fair values have been determined through information obtained from market sources and
management estimates.

Accounting for Derivative Instruments

On October 1, 2000, the Company adopted SFAS No. 133,Accounting for Derivative Instruments and Hedging
Activities, which establishes a new model for accounting for derivatives and hedging activities. It requires an entity to recognize all derivatives as either assets or
liabilities in the statement of financial position and measure these instruments at fair value. Upon adoption of SFAS No. 133, the Company recorded an unrealized loss on its investment in
derivatives, consisting of warrants to purchase Mechanical Technology Incorporated common stock in its results of operations as a
cumulative effect of a change in accounting principle of $1,021,725 to reflect the impact of adopting this accounting standard on October 1, 2000.

In
September 2000, the Emerging Issues Task Force issued EITF 00-19,Accounting for Derivative Financial Instruments Indexed to, and
Potentially Settled in, a Company's Own Stock, which requires freestanding contracts that are settled in a company's own stock, including common stock warrants, to

57

---

be designated as an equity instrument, asset or a liability. Under the provisions of EITF 00-19, a contract designated as an asset or a liability must be carried at fair value, with any
changes in fair value recorded in the results of operations. A contract designated as an equity instrument must be included within equity, and no fair value adjustments are required. In accordance
with EITF 00-19, the Company has determined that outstanding warrants as of September 30, 2001 to purchase 100,000 shares of the Company's Common Stock issued to Mechanical
Technology Incorporated should be designated as a liability and warrants to purchase 605,050 shares of the Company's Common Stock are designated as an equity instrument. Effective June 30,
2001, all warrants designated as a liability must be recorded as a liability and therefore, the Company reclassified the warrants designated as a liability from equity to liabilities, which had a fair
value on the issuance date of $1,505,421, using the Black-Scholes option-pricing model. At September 30, 2001, the outstanding warrants designated as a liability, as a result of the warrant
holders having rights that rank higher than those of common stockholders, have been recorded at a fair value of $234,699 through a reduction of $1,270,722 in the fair value included in the results of
operations. Effective December 28, 2001, the Company amended these warrants, removing the provisions providing the warrant holders with rights that rank higher than those of common
stockholders. As a result of the amendment, these warrants meet the criteria of equity instruments in accordance with EITF 00-19 and, therefore, the Company reclassified the value of these
warrants to equity from liabilities.

Accounting for Beneficial Conversion Feature

In November 2000, the Emerging Issues Task Force issued EITF 00-27,Application of Issue
No. 98-5 to Certain Convertible Instruments, which provides guidance on the calculation of a beneficial conversion feature on a convertible instrument. Based
upon the guidance provided in EITF 00-27, the Company has determined that the redeemable preferred stock issued in August 1999 and converted into the Company's Common Stock
in March 2000 had a beneficial conversion feature of $1,940,798. Under the guidance of EITF 00-27, the Company was required to record the beneficial conversion feature of $1,940,798
as a cumulative effect of a change in accounting principle upon adoption during the fiscal year ended September 30, 2001.

Reclassifications

Certain prior-year balances have been reclassified to conform to current-year presentations.

Recent Accounting Pronouncements

In August 2001, the Financial Accounting Standards Board ("FASB") issued SFAS No. 144,Accounting for the Impairment or
Disposal of Long Lived Assets,which supersedes SFAS No. 121,Accounting for the Impairment of Long-Lived Assets and for
Long-Lived Assets to be Disposed Of, and the accounting and reporting provisions of APB No. 30. SFAS No. 144 addresses financial accounting and
reporting for the impairment or disposal of long-lived assets and is effective for fiscal years beginning after December 15, 2001, and interim periods within those fiscal years. The
Company is currently reviewing this statement to determine its effect on the Company's consolidated financial statements.

In
April, 2002, the FASB issued SFAS No. 145,Rescission of FASB Statements No. 4, 44, and 64, Amendment of FASB Statement No. 13, and
Technical Corrections. SFAS No. 145 rescinds SFAS No. 4,Reporting Gains and Losses from Extinguishment of Debt,
and an amendment of that statement, SFAS No. 44,Accounting for Intangible Assets of Motor Carriers, and SFAS No. 64, Extinguishment of Debt Made to Satisfy Sinking-Fund
Requirements. This statement amends SFAS No. 13,Accounting for
Leases, to eliminate an inconsistency between the required accounting for sale-leaseback transactions. This statement also amends other existing authoritative
pronouncements to make various technical corrections, clarify meanings, or describe their applicability under changed conditions and is effective for fiscal years beginning after May 15, 2002.
The Company is currently reviewing this statement to determine its effect on its consolidated financial statements.

58

---

In July 2002, the FASB issued SFAS No. 146,Accounting for Costs Associated with Exit or Disposal Activities. SFAS
No. 146 addresses financial accounting and reporting for costs associated with exit or disposal activities and nullifies Emerging Issues Task Force (EITF) Issue No. 94-3, Liability Recognition for Certain Employee
Termination Benefits and Other Costs to Exit an Activity (including Certain Costs Incurred in a
Restructuring). This statement is effective for exit and disposal activities initiated after December 31, 2002. The Company is currently reviewing this statement to
determine its effect on its consolidated financial statements.

In
November 2001, the EITF issued Topic No. D-103 (Topic D-103) relating to the accounting for reimbursements received for
out-of-pocket expenses. In accordance with Topic D-103, reimbursements received for out-of-pocket expenses incurred should be characterized
as revenue in the statement of operations. The Company's arrangements have historically included reimbursement for expenses as part of the overall fee charged. As a result, the Company has
historically accounted for these reimbursements as revenue and recorded the associated costs as either cost of product revenue or funded research and development and other revenue expenses. As a
result, the Company's adoption of Topic D-103 had no impact on the Company's financial position, results of operations and cash flows.

D. MARKETABLE SECURITIES

At September 30, 2001, marketable securities have been categorized as available for sale, and as a result, are stated at fair value.

The
change in net unrealized gains during the fiscal year ended September 30, 2001 was $26,367 and is included in the balance sheet in a separate component of stockholders'
equity, net of tax effect. Proceeds from sales of marketable securities during fiscal year 2002, 2001 and 2000 were $9,889,273, $0 and $0, respectively. Gross realized gains from sale of securities
classified as available for sale during fiscal year 2002, 2001 and 2000 were $16,956, $0 and $0, respectively.

E.    UNBILLED CONTRACT COSTS AND FEES

Unbilled contract costs and fees represent revenue recognized in excess of amounts billed due to contractual provisions or deferred costs that have not yet been
recognized as revenue or billed to the customer. These amounts included retained fee and unliquidated costs totaling $66,699 and $173,685 at September 30, 2002 and 2001, respectively.

H.    INVESTMENT IN BEACON POWER CORPORATION

During the fiscal years ended September 30, 2000 and substantially all of the fiscal year ended September 30, 2001, the Company accounted for its
investment in Beacon Power under the equity method of accounting. During the fiscal years ended September 30, 2001 and 2000, the Company

60

---

recorded $5,065,034 and $899,493, respectively, of losses from Beacon Power, representing the Company's share of losses up to the extent of committed capital.

On
November 17, 2000, Beacon Power listed its common stock on the NASDAQ National Market. In connection with the listing, the put right granted to the Class D preferred
stockholders of Beacon Power was terminated and the contingent obligation to Class D preferred stockholders of Beacon Power was reclassified to additional paid-in capital.

On
November 22, 2000, Beacon Power completed an initial public offering of its common stock and issued 8,000,000 shares of its common stock at $6.00 per share. Upon the closing of
Beacon Power's initial public offering, each share of Beacon Power's class A, C, D, E and F preferred stock was converted into two shares of Beacon Power's common stock, or 29,359,530 shares of
common stock, of which the Company received 9,691,440 shares of Beacon Power's common stock. In addition, upon the closing of Beacon Power's initial public offering, Beacon Power issued 873,794 shares
of common stock in payment for consulting fees and accrued dividends on Beacon Power's class D and E preferred stock, of which the Company received 11,098 shares of Beacon Power's common stock.
After these events, the Company owned approximately 25.0% of Beacon Power's outstanding voting stock. In accordance with SAB No. 51, the Company's investment in Beacon Power and additional
paid-in capital was written up to reflect its beneficial interest in the book value of the stockholders' equity of Beacon Power at November 22, 2000, which was $14,988,382, less
losses previously recorded in connection with the put right obligation in the amount of $5,831,879 for a net gain of $9,156,503. On December 19, 2000, Beacon Power issued an additional
1,200,000 shares of its common stock at $6.00 per share to cover over-allotments. Upon the issuance of the additional 1,200,000 shares, the Company owned approximately 24.2% of Beacon
Power's outstanding voting stock. The Company's investment in Beacon Power and additional paid-in capital was written up in accordance with SAB No. 51 to reflect its beneficial
interest in the increase in book value of the stockholders' equity of Beacon Power at December 19, 2000, which was $1,622,721. On December 20, 2000, Beacon Power issued 985,507 shares of
its common stock in connection with the cashless exercise of warrants to purchase shares of Beacon Power's common stock. Upon the issuance of the additional 985,507 shares, the Company owned
approximately 23.7% of Beacon Power's outstanding voting stock. On December 22, 2000, Beacon Power issued 997,369 shares of its common stock in connection with the cashless exercise of warrants
to purchase shares of Beacon Power's common stock. Upon the issuance of the additional 997,369 shares, the Company owned approximately 23.1% of Beacon Power's outstanding voting stock.

After
the write-up of its investment in Beacon Power, the Company continued to account for its investment in Beacon Power under the equity method of accounting and recorded
its share of losses from Beacon Power on a one fiscal quarter trailing basis.

On
September 28, 2001, the Company distributed 5,000,000 shares of Beacon Power common stock to its stockholders. Upon the distribution of the 5,000,000 shares, the Company
recorded the distribution of the 5,000,000 shares as a reduction of additional paid-in-capital based on the book value per share prior to the distribution, or $0.59 per share.
After the distribution, the Company owned approximately 11.0% of Beacon Power's outstanding voting stock. Additionally, the Company has determined that it does not have the ability to exercise
significant influence over the operating and financial policies of Beacon Power and, therefore, now accounts for its investment in Beacon Power using the fair value method as set forth in SFAS
No. 115,Accounting for Certain Debt and Equity Securities. The Company is no longer required to record its share of any losses from Beacon Power
and the investment is carried at fair value and designated as available for sale and any unrealized holding gains or losses to be included in stockholders' equity as a component of accumulated other
comprehensive income/(loss). As of September 30, 2002, the Beacon Power common stock had a fair value of $800,005 and the Company recorded an unrealized loss of $6,352,979 in stockholders'
equity as a component of accumulated other comprehensive income/(loss).

61

---

As
of September 30, 2002, the fair market value of Beacon Power's common stock was $0.17 per share. The Company's cost basis in its investment in Beacon Power's common stock was
$0.59 per share. As of September 30, 2002, the Company believes the decline in market value represents an other than temporary decline because, among other things, the market value has been
less than cost since March 2002 and there is some uncertainty of the financial condition and near-term prospects of Beacon Power and, accordingly, the Company has recorded an other
than temporary write-down of its investment in Beacon Power of $1,400,000.

Additionally,
the Company has a warrant to purchase 173,704 shares of Beacon Power's common stock that has an exercise price of $1.25 per share and expires in 2005. The Company accounts
for this warrant in accordance with SFAS No. 133 and, therefore, records the warrant at its fair value. As of September 30, 2002, the warrant to purchase Beacon Power common stock had a
fair value of $14,365 and is included in warrants to purchase common stock on the accompanying balance sheet.

Beacon
Power accounted for $226,159, $242,460 and $470,996 of the Company's total revenue for the fiscal years ended September 30, 2002, 2001 and 2000, respectively. At
September 30, 2002 and 2001, the Company had $0 and $172,598, respectively, of accounts receivable and unbilled contract costs and fees from Beacon Power.

I.    LINE OF CREDIT

On September 13, 2002, the Company entered in a Loan and Security Agreement obtaining a $5 million revolving line of credit (the "Loan") with
Silicon Valley Bank (the "Bank"). Interest on outstanding
borrowings accrues at a rate equal the greater of (i) 6.75% per annum or (ii) at the Bank's prime rate of interest plus 2%. The Loan is secured by most of the assets of the Company and
is formula based with a 75% draw against eligible accounts receivables, as defined. As of September 30, 2002, there were no amounts outstanding under the Loan. Based on eligible accounts
receivables at September 30, 2002, the Company had $3 million available for borrowing. The terms of the Loan require the Company to raise $4 million of subordinated debt or equity
by December 1, 2002. In addition, the Loan contains certain financial covenants. The Loan matures on September 12, 2003. See Note B.

On
March 1, 1999, the Company reached a definitive settlement arrangement with Albert R. Snider (the "Settlement Agreement"), the holder of a note payable that commenced on
April 16, 1997, regarding a suit filed against Mr. Snider for breach of certain representations made by him, including statements of inventory balances in the Asset Purchase Agreement
dated as of April 3, 1997 between FMI and Mr. Snider relating to the purchase of the business of FMI and a counterclaim filed by Mr. Snider seeking, among other things, payments
allegedly due from the Company under a promissory note.

Pursuant
to the terms of the Settlement Agreement, the Company made a $100,000 cash payment to Mr. Snider on March 9, 1999 and the parties executed mutual general releases
dismissing any and all claims between them. In addition, the Settlement Agreement provides a right of first refusal in favor of the Company with respect to certain shares of the Company's Common
Stock, beneficially owned by Mr. Snider. Concurrently with the execution of the Settlement Agreement, the Company and Mr. Snider entered into a consulting agreement pursuant to which
Mr. Snider would perform certain consulting, advisory and related services as the Company may reasonably request from time to time between October 1, 1999 and October 1, 2002. In
exchange for these services, the Company issued 42,860 shares of its Common Stock to Mr. Snider, which were held by an escrow agent. The Company has recorded these shares held in escrow at
market value and as a reduction to stockholders' equity as of September 30, 1999.

On
April 26, 2000, the escrow agent, as authorized by the Company released the 42,860 shares of the Company's Common Stock that were held in escrow to Mr. Snider. The
Company recorded these securities at fair value until they were released from escrow at a market price of $16.00 per share or $685,760. The Company determined that the value of these securities
exceeded the net realizable value of the underlying services to be received by $235,760. The Company has charged this excess amount to selling, general and administrative expenses during the fiscal
year ended September 30, 2000. The Company was amortizing the realizable asset of $450,000 over the three-year period of service through September 30, 2002. At
September 30, 2001, the Company determined that the services provided under the consulting agreement will no longer be requested and has written off the unamortized asset of $150,000 to
selling, general and administrative expenses during the fiscal year ended September 30, 2001.

lease term. At September 30, 2002 and 2001, deferred rent expense amounted to $135,622 and $175,700, respectively.

Letters of Credit

The Company utilizes a standby letter of credit to satisfy security deposit requirements. This letter of credit is irrevocable and has a one-year
renewable term. Outstanding standby letters of credit as of September 30, 2002 and 2001 was $70,000. The Company is required to pledge cash as collateral on these outstanding letters of credit.

borrowing) per month; (2) an unused line fee in an amount equal to 0.50% per annum on the difference between $5 million and the average daily principal balance of the loans outstanding
during the month; and (3) a termination fee in the amount equal to (i) $50,000 if a Cancellation Event, as defined, occurs on or before March 13, 2003 or (ii) $25,000 if a

Royalty Agreements

In connection with the purchase of certain intellectual property, equipment and other assets from Sipex Corporation ("Sipex") on September 27, 2002, Sipex
will receive royalty payments of up to $183,500 based on cash receipts from existing backlog and between $400,000 and $1,050,000 from cash receipts from new business of Sipex products by the Company
for the subsequent three years.

Employment Agreements

The Company has employment agreements with certain employees that provide severance payments and accelerated vesting of options upon termination of employment
under certain circumstances or a change of control, as defined. As of September 30, 2002, the Company's potential minimum obligation to these employees was approximately $1,265,000.

Litigation

From time to time, the Company is a party to routine litigation and proceedings in the ordinary course of business. The Company is not aware of any current or
pending litigation to which the Company is or may be a party that the Company believes could materially adversely affect the Company's results of operations or financial condition.

L.    EMPLOYEE BENEFIT PLAN

The Company offers a 401(k) Employee Benefit Plan (the "Plan"). Under the Plan, any regular employee, as defined by the Plan, who has completed six months of
service and has attained the age of 21 years is eligible to participate. Under the terms of the Plan, an employee may defer up to 15% of his or her compensation through contributions to the
Plan. During 1999, the Company extended the Plan
to its wholly-owned U.S. subsidiaries. During 2002, the Company amended the Plan to, among other things, (1) allow any employee to be eligible to participate on his or her hire date;
(2) allow an employee to defer up to 100% of his or her compensation, as limited under IRC Section 402(g), through contributions to the Plan; (3) increase the Company's match to
100% in the Company's common stock up to the first 6% of an employee's pay that he or she contributes to the Plan; and

64

---

(4) make matching contributions in the Company's common stock which will be 100% vested. The match contribution will be determined in dollars and converted to shares of the Company's common
stock using the share price of the last business day of each calendar quarter. The Company recorded matching contributions to the Plan of $772,068, $398,281 and $366,264 during the fiscal years ended
September 30, 2002, 2001 and 2000, respectively. During 2002, the Company issued 202,049 shares of the Company's common stock valued at $423,091 as matching contributions to the Plan.

Deferred
income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the
amounts used for income tax purposes. As of September 30, 2002 and 2001, the components of the net deferred tax assets/(liabilities) are as follows:

A
valuation allowance against the recoverability of net deferred tax assets has been established because more likely than not the Company will not be able to utilize
certain deferred tax assets in future years. The Company has offset certain deferred tax liabilities with deferred tax assets which are expected to generate offsetting deductions within the same
periods. The recognition of a portion of the valuation allowance on the deferred tax asset related to the net unrealized loss on the available for sale securities will subsequently be applied directly
to other comprehensive income

At
September 30, 2002, the Company had net operating loss carry-forwards of approximately $61,000,000 and $44,000,000 for federal and state income tax purposes,
respectively. The federal net operating losses expire beginning September 30, 2007 through 2022. The state net operating losses will expire beginning September 30, 2003 through 2007. The
use of these losses may be limited due to ownership change limitations under Section 382 of the Internal Revenue Code.

N.    STOCKHOLDERS' EQUITY

Investment from Mechanical Technology Incorporated

On October 21, 1999, the Company received a $7,070,000 investment from Mechanical Technology Incorporated ("MTI"). In consideration for MTI's investment,
MTI received 1,030,000 shares of the Company's Common Stock at a discounted price of approximately $6.80 per share, and warrants to purchase an additional 100,000 shares of the Company's Common Stock
at an exercise price of $8.80 per share and an expiration date four years from the date of issuance. MTI funded $2,570,000 of its investment in the Company on October 21, 1999 and received
370,800 of the 1,030,000 shares of the Company's Common Stock and a warrant to purchase 36,000 of the 100,000 shares of the Company's Common Stock. MTI made the remaining investment on
January 31, 2000 of $4,500,000 and received the remaining 659,200 shares of the Company's Common Stock and a warrant to purchase the remaining 64,000 shares of the Company's Common Stock. The
Company incurred approximately $95,000 of legal, accounting, consultation and filing fees in connection with this transaction. The Company has valued the warrants issued to MTI on October 21,
1999 and January 31, 2000, at $231,912 and $1,273,509, respectively, using the Black-Scholes option-pricing model.

In
addition, the Company received a warrant to purchase 108,000 shares of MTI's common stock on October 21, 1999 and a warrant to purchase 192,000 shares of MTI's common stock on
January 31, 2000 at exercise prices of $12.56 per share, as adjusted to reflect a 3:1 stock split in April 2000, and expiration dates four years from the date of issuance. The Company
has valued the warrant received on October 21, 1999 and January 31, 2000 at $568,553 and $2,926,885, respectively, using the Black-Scholes option-pricing model, and has recorded the
warrants as an asset and additional paid in capital. In accordance with EITF No. 96-11,Accounting for Forward Contracts and Purchased Options to Acquire
Securities Covered by FASB Statement No. 115, options that are entered into to purchase securities that will be accounted for under SFAS No. 115 should, at
inception, be designated as held-to-maturity, available-for-sale, or trading and accounted for in a manner consistent with the accounting prescribed by
SFAS No. 115 for that category of securities. The Company has designated that the securities to be purchased under the warrant agreement will be available-for-sale
securities and, therefore, the Company has marked to market the fair value of the warrants at each reporting period date and has recorded any unrealized gains and losses as a component of accumulated
other comprehensive loss included in stockholders' equity. At September 30, 2000, the warrants have an unrealized loss of $1,021,725, which is included in accumulated other comprehensive loss
included in stockholders' equity.

66

---

On
October 1, 2000, the Company adopted SFAS No. 133,Accounting for Derivative Instruments and Hedging Activities, which
establishes a new model for accounting for derivatives and hedging activities. It requires an entity to recognize all derivatives as either assets or liabilities in the statement of financial position
and measure these instruments at fair value. Upon adoption of SFAS No. 133, the Company recorded the $1,024,725 unrealized loss on its investment in warrants to purchase MTI's common stock in
its results of operations as a cumulative effect of a change in accounting principle to reflect the impact of adopting this accounting standard on October 1, 2000. As of September 30,
2002 and 2001, the warrants to purchase MTI's common stock have a fair value of $1,623 and $375,479, respectively, using the Black-Scholes option-pricing model. During the fiscal year ended
September 30,
2002 and 2001, the Company recorded a unrealized loss in its statement of operations on the warrants to purchase MTI's common stock of $373,856 and $2,098,234, respectively.

Stock Options

Under the Company's 1992, 1994, 1996, 1998, 1999, 2000 and 2002 Stock Option Plans (collectively, the "Plans"), both qualified and non-qualified stock
options may be granted to certain officers, employees, directors and consultants to purchase up to 5,250,000 shares of the Company's Common Stock. At September 30, 2002, 4,452,344 of the
5,250,000 stock options available for grant under the Plans have been granted.

The
Plans are subject to the following provisions:

The
aggregate fair market value (determined as of the date the option is granted) of the Company's Common Stock that any employee may purchase in any calendar year pursuant to the
exercise of qualified options may not exceed $100,000. No person who owns, directly or indirectly, at the time of the granting of a qualified option to him or her, more than 10% of the total combined
voting power of all classes of stock of the Company shall be eligible to receive any qualified options under the Plans unless the option price is at least 110% of the fair market value of the
Company's Common Stock subject to the option, determined on the date of grant. Non-qualified options are not subject to this limitation.

Qualified
options are issued only to employees of the Company, while non-qualified options may be issued to non-employee directors, consultants and others, as
well as to employees of the Company. Options granted under the Plans may not be granted with an exercise price less than 100% of fair value of the Company's Common Stock, as determined by the Board of
Directors on the grant date.

Options
under the Plans must be granted within 10 years from the effective date of the Plan. Qualified options granted under the Plans cannot be exercised more than
10 years from the date of grant, except that qualified options issued to 10% or greater stockholders are limited to five-year terms. All options granted under the Plans provide for
the payment of the Company's exercise price in cash, or by delivery to the Company of shares of the Company's Common Stock already owned by the optionee having fair market value equal to the exercise
price of the options being exercised, or by a combination of such methods of payment. Generally, the options vest and become exercisable ratably over a four-year period.

67

---

The Plans contain antidilutive provisions authorizing appropriate adjustments in certain circumstances. Shares of the Company's Common Stock subject to options that expire without being
exercised or that are canceled as a result of the cessation of employment are available for further grants.

A
summary of the status of the Company's stock options as of September 30, 2002, 2001 and 2000 and changes for the fiscal years then ended are presented below.

valued the warrants issued to MTI on October 12, 1999 and January 31, 2000 at $231,912 and $1,273,509, respectively, using the Black-Scholes option-pricing model. At September 30,
2001, none of these warrants had been exercised. At September 30, 2001, the Company valued these warrants at $234,699 and had designated the warrants as a liability in accordance with EITF
00-19, as a result of the warrant holders having rights that rank higher than those of common stockholders. Effective December 28, 2001, the Company amended these warrants, removing
the provisions providing the warrant holders with right that rank higher than those of common stockholders. As a result of the amendment, these warrants meet the criteria of equity instruments in
accordance with EITF 00-19 and, therefore, the Company reclassified the value of these warrants to equity from liabilities.

On
November 16, 1999, in connection with the acquisition of certain intellectual property, equipment and other assets from Northrop Grumman Corporation, the Company issued a
warrant to purchase up to 100,000 shares of the Company's Common Stock at an exercise price of $9.725 per

share. The Company has valued this warrant at $631,000 using the Black-Scholes option-pricing model and has designated the warrant as an equity instrument in accordance with EITF 00-19.
As of September 30, 2002, all of this warrant had been exercised.

On
February 4, 2000, the Company issued to Northrop Grumman Corporation an additional warrant to purchase up to 100,000 shares of the Company's Common Stock at an exercise price
of $9.725 per share. This warrant was exercisable upon the occurrence of certain defined events. This warrant expires on December 31, 2006, but since these conditions were not met, this warrant
is no longer exercisable.

On
August 23, 2002, in connection with the Investment Banking Agreement with J.P. Turner & Company, LLC, the Company issued a warrant to purchase up to 250,000 shares of
the Company's Common Stock at an exercise price of $1.75 per share and vests in four equal installments. This warrant expires on August 23, 2005. The Company has valued this warrant at $299,925
using the Black-Scholes option-pricing model and has designated the warrant as an equity instrument in accordance with EITF 00-19. At September 30, 2002, none of these warrants were
exercised.

On
September 13, 2002, in connection with the Loan and Security Agreement between the Company and Silicon Valley Bank, the Company issued a warrant to purchase up to 181,951
shares of the Company's Common Stock at an exercise price of $1.374 per share. This warrant expires on September 13, 2007. The Company has valued this warrant at $210,895 using the
Black-Scholes option-pricing model and has designated the warrant as an equity instrument in accordance with EITF 00-19. At September 30, 2002, none of these warrants were
exercised.

Stock-based Compensation

During 2001, the Company accelerated the vesting schedule of a stock option award in connection with an employee termination and recorded a charge of $111,250 to
selling, general and administrative expenses, based on the intrinsic value of the stock options.

Had
compensation cost for the Company's stock-based compensation been determined based on fair value at the grant dates as calculated in accordance with SFAS No. 123, the
Company's net loss and loss per share for the fiscal years ended September 30, 2002, 2001 and 2000 would have been increased to the pro forma amounts indicated below:

|            |  | 2002 |             | 2001 |   | 2000  |  
|----------- |  | ---- | ----------- | ---- | - | ----- | -
|
|As reported |  | $    | (20,760,598 | )    | $ | (1.25 | )
|Pro forma   |  | $    | (25,654,880 | )    | $ | (1.55 | )

The
effects of applying SFAS No. 123 in this pro forma disclosure are not indicative of future amounts. SFAS No. 123 does not apply to awards prior to 1996 and additional
awards in future years are anticipated.

The
fair value of each stock option is estimated on the date of the grant using the Black-Scholes option-pricing model with the following assumptions: an expected life of seven years,
expected volatility ranging from 86.0% to 114.4%, no dividends, and risk-free interest rate ranging from 4.00% to 4.50% for the fiscal year ended September 30, 2002; an expected
life of seven years, expected volatility ranging from 96.6% to 125.0%, no dividends, and risk-free interest rate ranging from 4.50% to 5.87% for the fiscal year ended September 30,
2001; and an expected life of seven years, expected volatility ranging from 80.1% to 112.3%, no dividends, and risk-free interest rate of 6.17% for the fiscal year ended

70

---

September 30, 2000. The weighted average price of the fair value of options granted for the fiscal years ended September 30, 2002, 2001 and 2000 are $3.62, $9.64 and $14.05,
respectively.

In
March 2000, the FASB issued Interpretation No. 44, "Accounting for Certain Transactions Involving Stock Compensation, an Interpretation of APB Opinion No. 25."
This interpretation clarifies the application of APB Opinion No. 25, including (a) the definition of employee for purposes of applying APB Opinion No. 25, (b) the criteria
for determining whether a plan qualifies as a noncompensatory plan, (c) the accounting consequences of various modifications to the terms of a previously fixed stock option or award, and
(d) the accounting for an exchange of stock compensation awards in a business combination. The Interpretation is effective July 1, 2000, and the effects of applying the Interpretation
are recognized on a prospective basis. The adoption of this Interpretation did not have a material impact on the Company's financial condition or results of operations.

Common Stock Offering

On October 30, 2000, the Company filed for a public offering of its Common Stock. In connection with this offering, the Company incurred $1,325,606 of
equity financing costs as of March 31, 2001. On April 25, 2001, the Company announced that it would not proceed with this public offering and the Company filed an amendment to the
registration statement it initially filed, converting the filing to a shelf registration statement. Accordingly, the Company has expensed the $1,325,606 costs incurred associated with the initial
registration statement. On June 1, 2001, the Company completed its shelf registration statement and incurred an additional $95,021 in expenses in connection with the shelf registration
statement and has expensed these costs as incurred during the three months ended June 30, 2001.

On
June 6, 2001, the Company issued 1,464,928 shares of its Common Stock at a price of $12.125 per share for gross proceeds of $17,762,252. The Company incurred issuance costs of
$671,679 related to this transaction.

O.    PREFERRED STOCK

The Company is authorized to issue up to 1,000,000 shares of Preferred Stock, $0.01 par value per share ("Preferred Stock"). The Preferred Stock may be issued in
one or more series, the terms of which may be determined at the time of issuance by the Board of Directors, without further action by stockholders, and may include voting rights (including the right
to vote as a series on particular matters), preferences as to dividends and liquidation, conversion and redemption rights and sinking fund provisions.

On
August 25, 1999, the Company completed an $8 million private placement of 8,000 shares of its Series A Redeemable Convertible Preferred Stock, $0.01 par value per
share (the "Series A Preferred Stock"), with Brown Simpson Strategic Growth Funds ("Brown Simpson"). The Series A Preferred Stock was convertible into 1,025,641 shares of the Company's
Common Stock, $0.01 par value per share (the "Common Stock").

In
connection with the transaction, Brown Simpson also received warrants to purchase up to 675,000 fully vested and immediately exercisable additional shares of Common Stock at $8.54 per
share (the "Brown Simpson Warrants"). The Brown Simpson Warrants expire on August 25, 2003. The Company has valued these warrants at $1,818,558 based on the fair value of these warrants, as
determined by the Black-Scholes option-pricing model, and has recorded this amount as a discount to the Preferred Stock. In addition, the Company incurred direct costs of $1,338,234 in connection with
this preferred stock offering which have also been recorded as a discount to the Series A Preferred Stock.

H.C.
Wainwright & Co., Inc. ("H.C. Wainwright") served as placement agent for the transaction and received a commission of $560,000 and warrants to purchase 120,000 shares
of the Company's Common Stock at $7.80 per share. These warrants expire on August 25, 2003. H.C. Wainwright will also receive a future fee in the amount of 4% of any monies received by the
Company upon the exercise of the Brown Simpson Warrants. The Company has recorded the fair value of these warrants, as determined by the Black-Scholes option-pricing model, of $550,734 as a discount
to the Series A Preferred Stock.

The
Company valued the Series A Preferred Stock at issuance to be $4,843,208 based on the relative fair market values of the financial instruments issued in connection with this
placement and net of
offering costs. The Company was accreting the carrying value of the preferred stock to its redemption value of $8,000,000 at August 25, 2003, using the effective interest method.

On
March 7, 2000, the preferred stockholders elected to convert all 8,000 shares of the Series A Preferred Stock into 1,025,641 shares of the Company's Common Stock, which
resulted in the accretion of an additional $3,105,888 of the discount on the redeemable preferred stock during the fiscal year ended September 30, 2000.

In
November 2000, the Emerging Issues Task Force issued EITF 00-27, "Application of Issue No. 98-5 to Certain Convertible
Instruments," which provides guidance on the calculation of a beneficial conversion feature on a convertible instrument. Based upon the guidance provided in EITF
00-27, the Company has determined that the redeemable preferred stock issued in August 1999 and converted into the Company's Common Stock in March 2000 had a beneficial
conversion feature of $1,940,798. Under the guidance of EITF 00-27, the Company is required to record the beneficial conversion feature of $1,940,798 as a cumulative effect of a change in
accounting principle upon adoption during the fiscal year ended September 30, 2001.

P.    SIGNIFICANT CUSTOMERS

Northrop Grumman Corporation

On November 16, 1999, the Company purchased certain intellectual property, equipment and other assets from Northrop Grumman Corporation ("NGC"). These
assets were used by NGC in connection with its power electronics product business. The Company is amortizing the purchase price allocated to completed technology on a straight-line basis
over a 10-year period. The Company is depreciating the purchase price allocated to property and equipment on a straight-line basis over a 10-year period. The
Company also entered into (i) a sublease with NGC pursuant to which it agreed to a five-year sublease for approximately 14,863 square feet of rentable space in the Baltimore,
Maryland area and (ii) a three-year Transition Services Agreement providing the Company access to certain test facilities and personnel of NGC on a fee basis. In consideration for
these foregoing assets and agreements, NGC received 578,761 shares of the Company's Common Stock valued at $8.3438 per share or $4,829,066. In addition, the Company issued to NGC a warrant to purchase
an additional 100,000 shares of the

Company's Common Stock at an exercise price of $9.725 per share. The Company has recorded the fair value of this warrant, as determined by the Black-Scholes option-pricing model, of approximately
$631,000 and approximately $119,000 of legal, accounting, consultation and filing fees as a cost of this transaction. On February 4, 2000, the Company issued to NGC an additional warrant to
purchase 100,000 shares of the Company's Common Stock at an exercise price of $9.725 per share. This warrant
is exercisable upon the occurrence of certain defined events, none of which had occurred as of September 30, 2000. The purchase price of the asset purchase has been allocated as follows:

The
pro forma financial information has not been presented, as this transaction is the purchase of assets rather than as a business combination. The Company has determined that this
transaction was the acquisition of assets and not the acquisition of a business as this business ceased operations more than 12 months prior to this acquisition of assets, the Company did not
acquire facilities, employees or customer base and there is not sufficient continuity of the acquired entity's operations prior to and after the transaction.

For
the fiscal year ended September 30, 2002, 2001 and 2000, the Company recognized $603,303, $239,532 and $413,991, respectively, of revenue, primarily related to funded research
and development arrangements, from NGC. At September 30, 2002 and 2001, the Company had $61,711 and $64,437, respectively, of accounts receivable and unbilled contract costs and fees from NGC.

Inverpower Controls Ltd.

On July 13, 2001, the Company acquired substantially all of the assets and assumed certain certain liabilities of Inverpower Controls Ltd., a
corporation based in Burlington, Ontario, Canada ("Inverpower"). Inverpower is a manufacturer of power electronics modules and advanced high-speed digital controls for use in industrial
power-supply, power conversion and power quality systems. The

T.    SEGMENT DISCLOSURES

The Company's organizational structure is based on strategic business units that perform services and offer various products to the principal markets in which the
Company's products are sold. These business units equate to three reportable segments: Applied Technology, Power Systems and Electronics.

The
Company's Technology Center and its Electronic Power Products operation in Maryland perform research and development services in collaboration with third parties. The MagMotor
Division, Ling Electronics and Advanced Fuel Cell Power products operations specialize in the engineering and manufacturing of power systems. Film Microelectronics, Inc designs and manufactures
electronic products. The Company's principal operations and markets are located in the United States.

The
accounting policies of each of the segments are the same as those described in the summary of significant accounting policies. The Company evaluates performance based on revenue and
profit and loss from operations, excluding the effects of the write-off of the public offering costs, amortization of goodwill and intangible assets associated with acquisitions and
restructuring costs. Common costs not directly attributable to a particular segment are included in the Applied Technology segment. These costs include corporate costs such as executive and officer
compensation, facility costs, legal, audit and tax and other professional fees and totaled $4,194,338 and $4,025,800 for the fiscal year ended September 30, 2002 and 2001, respectively.

The
following is a summary of the Company's operations by operating segment:

U.    RESTRUCTURING COSTS

During April 2002, the Company commenced a restructuring plan designed to streamline its production base, improve efficiency and enhance its competitiveness and
recorded a restructuring charge of $1.5 million. The restructuring charge includes approximately $655,000 for severance costs associated with the reduction of approximately 60 employees, or 17%
of the work force. The reductions occurred in the following business segments: Applied Technology9: Corporate2; Electronics16; and Power Systems33.
On a functional basis, the reductions were: manufacturing45; research and development4; and selling, general and administrative11. As of September 30,
2002, 56 employees have been terminated and the remaining 4 are expected to be terminated by March 2003. In addition, as of September 30, 2002, $507,504 of the severance has been paid and the
remaining severance will be paid by March 2003. The balance of the restructuring charge relates to the closing of the Anaheim, CA facility. These costs include approximately $270,000 of cash charges
primarily related to rent, real estate
taxes and operating costs to be paid through the remainder of the lease and an estimated $350,000 of other cash charges for restoration and clean-up. In addition, approximately $225,000 of
the restructuring charge relates to non-cash charges on assets to be disposed of. The Company anticipates the Anaheim, CA manufacturing facility will be closed during the second quarter of
fiscal year 2003.

Item 9. CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE

The Audit Committee of the Board of Directors (the "Audit Committee) of the Registrant annually considers and recommends to the Registrant's Board of Directors
the selection of the Registrant's independent auditors. As recommended by the Audit Committee, the Board of Directors on June 21, 2002 dismissed the Registrant's independent auditors, Arthur
Andersen LLP ("Andersen"), and engaged Grant Thornton LLP ("Grant Thornton") as its independent auditors and to audit the Registrant's financial statements for the fiscal year ended
September 30, 2002.

Andersen's
reports on the financial statements of the Registrant for the two most recent fiscal years ended September 30, 2001 and September 30, 2000 did not contain an
adverse opinion or a disclaimer of opinion, nor were they qualified or modified as to uncertainty, audit scope or accounting principles.

During
the two most recent fiscal years ended September 30, 2001 and September 30, 2000, and the subsequent interim period through the date of Andersen's dismissal, there
were (i) no disagreements with Andersen on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure which, if not resolved to Andersen's
satisfaction, would have caused Andersen to make reference to the subject matter of such disagreement in connection with its reports on the financial statements of the Registrant, and (ii) no
reportable events as listed in Item 304(a)(1)(v) of Regulation S-K.

During
the two most recent fiscal years ended September 30, 2001 and September 30, 2000, and the subsequent interim period through the date of Grant Thornton's engagement,
neither the Registrant nor anyone on its behalf has consulted Grant Thornton regarding either (i) the application of accounting principles to a specified transaction, either completed or
proposed; or the type of audit opinion that might be rendered on the Registrant's financial statements, and neither a written report was provided to the Registrant nor oral advice was provided to the
Registrant that Grant Thornton concluded was an important factor considered by the Registrant in reaching a decision as to any accounting, auditing or financial reporting issue; or (ii) any
matter that was either the subject of a disagreement (as defined in Item 304(a)(1)(iv) of Regulation S-K and the related instructions to Item 304(a) of
Regulation S-K), or a reportable event (as described in Item 304(a)(1)(v) of Regulation S-K).
