ITEM 1 - BUSINESS

The Company

Vicor Corporation was incorporated in Delaware in 1981. Unless the context
indicates otherwise, the term "Company" means Vicor Corporation and its
consolidated subsidiaries. The Company designs, develops, manufactures and
markets modular power components and complete power systems using an innovative,
patented, high frequency electronic power conversion technology called "zero
current switching." Power systems, a central element in any electronic system,
convert power from a primary power source (e.g., a wall outlet) into the stable
DC voltages that are required by most contemporary electronic circuits.

In 1987, the Company formed VLT Corporation as its licensing subsidiary.
During 2000, the Company reincorporated VLT Corporation in California by merging
it with and into VLT, Inc., a wholly-owned subsidiary of the Company. In 1990,
the Company established a Technical Support Center in Germany and a foreign
sales corporation (FSC). In 1995, the Company established Technical Support
Centers in France, Italy, Hong Kong, and England. Also in 1995, the Company
established Vicor Integration Architects ("VIA's"), most of which are majority
owned subsidiaries. VIA's provide customers with local design and manufacturing
services for turnkey custom power solutions. At December 31, 2000 there were
five (5) VIA's operating in the United States. In 1996, the Company established
Vicor B.V., a Netherlands company, which serves as a European Distribution
Center. In 1998, the Company acquired the principal assets of the switching
power supply businesses owned by the Japan Tobacco, Inc. group and established a
direct presence in Japan through a new subsidiary called Vicor Japan Company,
Ltd. ("VJCL"). VJCL markets and sells the Company's products and provides
customer support in Japan. The Company's Common Stock became publicly traded on
the NASDAQ National Market System in April 1990.

Products

Power systems are incorporated into virtually all electronic products,
such as computers and telecommunications equipment, to convert electric power
from a primary source, for example a wall outlet, into the stable DC voltages
required by electronic circuits. Because power systems are configured in a
myriad of application-specific configurations, the Company's basic strategy is
to exploit the density and performance advantages of its technology by offering
comprehensive families of economical, component-level building blocks which can
be applied by users to easily configure a power system specific to their needs.
In addition to component-level power converters, which serve as modular power
system building blocks, the Company also manufactures and sells complete
configurable power systems, accessory products, and custom power solutions. The
Company's principal product lines include:

Modular Power Converters

The Company currently offers four first-generation families of
component-level DC-DC power converters: the VI-200, VI-J00, MI-200, and MI-J00
families. Designed to be mounted directly on a printed circuit board assembly
and soldered in place using contemporary manufacturing processes, each family
comprises a comprehensive set of products which are offered in a wide range of
input voltage, output voltage and power ratings. This allows end users to select
products appropriate to their individual applications.


1
The product families differ in maximum power ratings, performance
characteristics, package size and, in the case of the "MI" families, in target
market. The MI families are designed specifically to meet many of the
performance and environmental requirements of the military/defense markets.

In 1998, the Company introduced the first complete family of its
second-generation of high power density, component-level DC-DC converters. This
family operates from 48 Volts input and is designed for the telecommunications
market as well as distributed power systems. It consists of 26 modules with the
most popular output voltages in all three of the Company's second-generation
standard packages: the full size (Maxi), the half size (Mini) and the quarter
size (Micro). Output power levels from 50 to 500 Watts are covered by this
offering. In 1999, this was followed by two additional families: a 300 Volt
input for off-line (rectified 115 or 230 Volt ac) and distributed power
applications, and a 375 Volt input specifically designed for use in power factor
corrected systems. This latter family increased the power available to 600
Watts.

In November 2000, the Company introduced a new power conversion
architecture, called PowerStick, which is specifically designed to address the
market for low profile, high density, board mounted DC-DC converters. PowerStick
converters will be able to deliver up to 75 Watts per module and up to 900 Watts
in fault tolerant arrays.

Configurable Products

Utilizing its standard converters as core elements, the Company has
developed several product families which provide complete power solutions
configured to a customer's specific needs. These products exploit the benefits
of the component-level approach to offer higher performance, higher power
densities, lower costs, greater flexibility and faster delivery than traditional
competitive offerings.

Most electronic and data processing ("EDP") and industrial electronic
products operate directly off of AC lines. "Off-line" power systems require
"front end" circuitry to convert AC line voltage into DC voltage for the core
converters. The Company's off-line AC-DC products incorporate a set of modular
front end subassemblies to offer a complete power solution from AC line input to
highly regulated DC output. The product selection includes a low-profile modular
design in various sizes and power levels, and a choice of alternatives to
conventional "box switchers"--high power, off-line bulk supplies in
industry-standard packages. Voltage and power levels are either factory or field
configurable.

Many telecommunications, defense and industrial electronic products are
powered from central DC sources (battery plants or generators). The Company's
DC-DC power system choices include a low-profile modular design similar to the
corresponding AC-DC system and a rugged, compact assembly for chassis-mounted,
bulk power applications.

Accessory Power System Components

Accessory power system components, used with the Company's component-level
power converters, integrate other important functions of the power system,
facilitating the design of complete power systems by interconnecting several
modules. In general, accessory products are used to condition the inputs and
outputs of the Company's modular power components.

VI-HAMs (Harmonic Attenuator Modules) are universal-AC-input,
power-factor-correcting front ends for use with compatible power converters.
VI-AIMs (AC Input Modules) provide input filtering, transient protection and
rectification of the AC line. VI-IAMs (Input Attenuator Modules) provide the DC
input filtering and transient protection required in industrial and
telecommunications markets. VI-RAMs (Ripple Attenuator Modules) condition
converter module outputs for extremely low noise systems. In 1998, the Company
doubled the power capability of its component-level AC front end, the VI-ARM (AC
Rectifier Module). This new front end product is packaged in the same "Micro"
package and includes a microcontroller that tracks the AC line to ensure correct
operation for domestic or international line voltages. In addition, two
accessory products for the 48 Volt input second-generation family were
introduced in 1999: the FiltMod for input filtering and the IAM48 for transient
and spike protection.


2
Customer Specific Products

Since its inception, the Company has accepted a certain amount of "custom"
power supply business. In most cases, the customer was unable to obtain a
conventional solution which could achieve the desired level of performance in
the available space. By utilizing its component-level power products as core
elements in developing most of these products, the Company was able to meet the
customer's needs with a reliable, high power density, total solution. However,
in keeping with the Company's strategy of focusing on sales of standard families
of component-level power building blocks, custom product sales have not been
directly pursued. The Company has traditionally pursued these custom
opportunities through Value-Added-Resellers ("VAR's"). The Company has
established a network of VIA's (see "The Company," above in Item 1 -
"Business"). Most of the VIA's are majority owned by the Company, while VAR's
are independent businesses. Both VIA's and VARs are distributed geographically
and are in close proximity to many of their customers.

Sales and Marketing

The Company sells its products through a network of 33 independent sales
representative organizations in North and South America; internationally, 50
independent distributors are utilized. Sales activities are managed by a staff
of Regional and Strategic Sales Managers and sales personnel based at the
Company's world headquarters in Andover, Massachusetts, its Westcor division in
Sunnyvale, California, a Technical Support Center in Lombard, Illinois, and in
its Technical Support Center subsidiaries in Munich, Germany; Camberley Surrey,
England; Milan, Italy; Paris, France; Hong Kong and Tokyo, Japan.

Export sales, as a percentage of total net revenues, were approximately
32%, 30% and 29%, in 2000, 1999 and 1998, respectively.

Because of the technical nature of the Company's product lines, the
Company engages a staff of Field Applications Engineers to support the Company's
sales activities. Field Applications Engineers provide direct technical sales
support worldwide to review new applications and technical matters with existing
and potential customers. There are Field Application Engineers assigned to all
Company locations and are supported by product specialists (Product Line
Engineers) located in Andover. The Company generally warrants its standard
products for a period of two years.

The Company also sells directly to customers through Vicor Express, an
in-house distribution group. Through advertising and periodic mailing of its
catalogs, Vicor Express generally offers customers rapid delivery on small
quantities of many standard products. The Company, through Vicor B.V., has
expanded its Vicor Express operation to include locations in Germany, France,
Italy and England.

Customers and Applications

The Company's customer base is comprised of large Original Equipment
Manufacturers (OEMs) and smaller, lower volume users which are broadly
distributed across several major market areas. Some examples of the diverse
applications of the Company's products are:

Telecommunications: EDP:
Central Office Systems RAID Systems
Fiber Optic Systems Supercomputers
Cellular Telecommunications Data Storage Systems
Microwave Communications ATM Switches
Voice Processing Multiplexers Networking Equipment
Paging Equipment LAN/WAN Systems
Broadcast Equipment File Servers
Power Amplifiers Optical Switches

Measurement and Control:                Military:
Process Control Equipment Communications
Medical Equipment Airborne Radar and Displays
Seismic Equipment Aircraft/Weapons Test Equipment
Test Equipment Ruggedized Computers
Transportation Systems Electro-Optical Systems
Agricultural Equipment IR Reconnaissance/Targeting Systems
Marine Products

For the years ended December 31, 2000, 1999 and 1998, no single customer
accounted for more than 10% of net revenues.

Backlog

As of December 31, 2000, the Company had a backlog of approximately $70.3
million compared to $58.7 million at December 31, 1999. Backlog is comprised of
orders for products which have a scheduled shipment date within the next 12
months. The Company believes that a substantial portion of sales in each quarter
is, and will continue to be, derived from orders booked in the same quarter.

Research and Development

As a basic element of its long term strategy, the Company is committed to
the continued advancement of power conversion technology and power component
product development. The Company's research and development efforts are focused
in three areas: continued enhancement of the Company's patented technology;
expansion of the Company's families of component level DC-DC converter products;
and continued development of configurable products based upon market
opportunities. The Company invested approximately $20.6 million, $19.9 million
and $20.7 million, in research and development in 2000, 1999 and 1998,
respectively. Investment in research and development represented 8.0%, 10.5% and
12.5%, of net revenues in 2000, 1999 and 1998. The Company plans to continue to
invest a significant percentage of revenues into research and development.

Manufacturing

The Company's principal manufacturing processes consist of assembly of
electronic components onto printed circuit boards, automatic testing of
components, wave, reflow and infrared soldering of assembled components,
encapsulation of converter subassemblies, final "burn-in" of certain products
and product test using automatic test equipment.

The Company continues to pursue its strategy to minimize manual assembly
processes, reduce manufacturing costs, increase product quality and reliability
and ensure its ability to rapidly and effectively expand capacity. The strategy
is based upon the phased acquisition and/or fabrication, qualification and
integration of automated manufacturing equipment. The Company plans to make
continuing investments in manufacturing equipment, particularly for the
Company's second-generation products, in order to expand capacity (see "-
Second-Generation Automated Manufacturing Line," below).

Components used in the Company's products are purchased from a variety of
vendors. Most of the components are available from multiple sources. In
instances of single source items, the Company maintains levels of inventories it
considers to be appropriate. Incoming components, assemblies and other parts are
subjected to several levels of inspection procedures.

Compliance by the Company with applicable environmental laws has not had a
material effect on the financial condition or operations of the Company.


4
Second-Generation Automated Manufacturing Line

Shipments of second-generation products approximately doubled in 2000 over
1999. Both first and second-generation products are sold to similar customers.
The Company continues to refine the designs, processes, equipment and parts
associated with second-generation products. The Company began depreciation on a
significant portion of the second-generation automated manufacturing line,
approximately $32.5 million, in the second quarter of 1998. Depreciation on
another $1.6 million of the line commenced during the second half of 1998.
Approximately $3.3 million of these initial costs are being depreciated on a
straight-line basis over a period of five years, and approximately $30.8 million
are being depreciated on a straight-line basis over a period of eight years.
Additional equipment of approximately $4.8 million was placed into service
during 2000 ($6.4 million in 1999). While unit production in 2000 more than
doubled compared to 1999, gross margins on second-generation products continue
to be significantly lower than those of first-generation products. The Company
is taking steps to increase the capacity of second-generation manufacturing,
which includes adding equipment and re-deploying personnel and equipment from
first-generation production. The Company is also in the process of completing an
upgrade to second-generation products, internally designated as FasTrak, which
the Company anticipates will also help to increase capacity and reduce costs. It
will take several quarters before these steps will be fully implemented and
their effects realized. Gross margins during 2001 will continue to be negatively
impacted until higher production volumes, higher yield levels and component cost
reductions are attained with respect to second-generation products.

Competition

Many power supply manufacturers target markets similar to those of the
Company. Representative examples are: Lambda Electronics, a subsidiary of
Invensys, plc; the former Power Systems business unit of Lucent Technologies,
now a subsidiary of Tyco International, Ltd.; Artesyn Technologies; Astec
America, a subsidiary of Emerson Electronic Company; Power-One, Inc.; and C&D
Technologies, Inc., Power Electronics Division. Although certain of the
Company's competitors have significantly greater financial and marketing
resources and longer operating histories than the Company, the Company believes
that it has a strong competitive position, particularly with customers who need
small, high density power system solutions requiring a variety of input-output
configurations.

Patents

The Company believes that its patents afford significant advantages by
erecting fundamental and multilayered barriers to competitive encroachment upon
key features and performance benefits of its principal product families. The
Company's patents cover the fundamental conversion topologies used to achieve
the performance attributes of its converter product lines; converter array
architectures which are the basis of the products' "parallelability"; product
packaging design; product construction; high frequency magnetic structures; and
automated equipment and methods for circuit and product assembly.

On February 16, 1999, the United States Patent and Trademark Office issued
U.S. patent RE36,098 (the "Reissue Patent") as a reissue of U.S. Patent
4,441,146 (the "Reset Patent"). The Reissue Patent includes original claims 1
through 5 of the Reset Patent plus 38 additional new claims. The claims in the
Reissue Patent cover non-coincident active clamp technology in a broadly defined
class of single-ended forward converters and enable design of power converters
which are smaller and more energy efficient than conventional power supplies.
The claims cover, but are not limited to, so-called "zero-voltage switching"
("ZVS") technology. The Company believes that its rights under the Reset Patent
and the Reissue Patent have been and are being infringed. The Company believes
in vigorously protecting its rights under its patents (see "Item 3 - Legal
Proceedings" below).

The Company has been issued 72 patents in the United States (which expire
between 2001 and 2018), 20 in Europe (which expire between 2002 and 2015 ), and
22 in Japan (which expire between 2002 and 2016). The Company also has a number
of patent applications pending in the United States, Europe and the Far East.
Although the Company believes that patents are an effective way of protecting
its technology, there can be no assurances that the Company's patents will prove
to be enforceable (see, e.g., "Item 3 - Legal Proceedings" below). While some of
the Company's patents are deemed materially important to the Company's
operations, the Company believes that no one patent is essential to the success
of the Company.


5
Licensing

In addition to generating revenue, licensing is an element of the
Company's strategy for building worldwide product and technology acceptance and
market share. In granting licenses, the Company retains the right to use its
patented technologies, and manufacture and sell its products, in all licensed
geographic areas and fields of use. Licenses are granted and administered
through the Company's wholly owned subsidiary, VLT, Inc., the successor to VLT
Corporation, which owns the Company's patents. Revenues from licensing
arrangements have not exceeded 10% of the Company's consolidated revenues in any
of the last three fiscal years.

Employees

As of December 31, 2000, the Company employed approximately 1,654 full
time and 353 part time people. The Company believes that its continued success
depends, in part, on its ability to attract and retain qualified personnel.
Although there is strong demand for qualified technical personnel, the Company
has not to date experienced difficulty in attracting and retaining sufficient
engineering and technical personnel to meet its needs (See "- Risk Factors -
Dependence on Key Personnel," below).

None of the Company's employees is subject to a collective bargaining
agreement. The Company has not experienced any work stoppages and believes that
its employee relations are good.

Risk Factors

This Annual Report on Form 10-K contains forward-looking statements within
the meaning of Section 27A of the Securities Act of 1933, as amended, and
Section 21E of the Securities Exchange Act of 1934, as amended. Actual results
could differ materially from those projected in the forward-looking statements
as a result of, among other factors, the risk factors set forth below.

Need for Technological Developments

The power supply industry and the industries in which many of our
customers operate are characterized by intense competition, rapid technological
change, product obsolescence and price erosion for mature products, each of
which could have an adverse effect on the Company's results of operations. The
failure of the Company to continue to develop and commercialize leading-edge
technologies and products that are cost effective and maintain high standards of
quality, could have a material adverse affect on the Company's competitive
position and results of operations.

Dependence on Customers' Business Prospects

The Company manufactures modular power components and power systems that
are incorporated into its customers' electronic products. The Company's growth
is therefore dependent on the continued growth in the sales of its customers'
products as well as the development by its customers of new products. The
failure of the Company to anticipate changes in our customers' businesses and
their changing product needs could negatively impact our financial position.

Need to Provide Additional Manufacturing Capacity

In order to meet anticipated future growth, the Company will need to
continue to increase manufacturing capacity through the installation of
additional equipment and additional automated manufacturing lines. The Company
has been working to increase the capacity for second-generation products through
the acquisition of new equipment and the re-deployment of equipment and
personnel from first-generation production. This will continue to increase fixed
costs and could have a negative impact on the Company's gross margins and
profitability. In addition, the process of installing equipment and new lines,
as well as hiring and training new personnel, could cause disruptions in
production or delays in the shipping of products.


6
Dependence on Third Party Suppliers and Subcontractors

The Company depends on third party suppliers and subcontractors to provide
components and assemblies used in our products. If suppliers or subcontractors
cannot provide their products or services on time or to our specifications, the
Company may not be able to meet the demand for its products or it may negatively
affect delivery times. In addition, the Company cannot directly control the
quality of the products and services provided by third parties. In order to
grow, the Company may need to find new or change existing suppliers and
subcontractors. This could cause disruptions in production, delays in the
shipping of product or increases in prices paid to third-parties.

Foreign Sales and Distribution

International sales have been and are expected to be a significant
component of total sales. Dependence on foreign third parties for sales and
distribution is subject to special concerns, such as: foreign economic and
political instability, foreign currency controls and market fluctuations, trade
barriers and tariffs, foreign regulations and exchange rates.

Dependence on Key Personnel

The Company's success depends on our ability to retain the services of its
executive officers. The loss of one or more members of senior management could
adversely affect the Company's business and financial results. In particular,
the Company is dependent on the services of Dr. Patrizio Vinciarelli, its
founder, Chairman, President and Chief Executive Officer. The loss of the
services of Dr. Vinciarelli could have a material adverse effect on the
Company's development of new products and on its results of operations. In
addition, the Company depends on highly skilled engineers and other personnel
with technical skills that are in high demand and are difficult to replace. The
Company's continued operations and growth depends on its ability to attract and
retain highly qualified employees in a very competitive employment market.

Patents and Proprietary Rights

The Company operates in an industry in which the ability to compete
depends on the development or acquisition of proprietary technologies which must
be protected to preserve the exclusive use of such technologies. The Company
devotes substantial resources to establish and protect our patents and
proprietary rights, and relies on patent and intellectual property law to
protect such rights. Such protection, though, may not prevent competitors from
independently developing products similar or superior to the Company's products.
The Company may be unable to protect or enforce current patents, may rely on
unpatented technology that competitors could restrict or may be unable to
acquire patents in the future, and this may have a material adverse affect on
the Company's competitive position. In addition, the intellectual property laws
of foreign countries may not protect the Company's rights to the same extent as
those of the United States. The Company has been and may need to continue to
defend or challenge patents. The Company may incur significant costs in and
devote significant resources to these efforts which, if unsuccessful, may have a
material adverse effect on its results of operations.

ITEM 2 - PROPERTIES

The Company's corporate headquarters building, which the Company owns and
is located in Andover, Massachusetts, provides approximately 90,000 square feet
of office space for its sales, marketing, engineering and administration
personnel.

The Company also owns a building of approximately 230,000 square feet, in
Andover, Massachusetts which houses all Massachusetts manufacturing activities.

The Company's Westcor division owns and occupies a building of
approximately 31,000 square feet in Sunnyvale, California.


7
ITEM 3 - LEGAL PROCEEDINGS

On February 1, 1999, the Company announced that it had concluded an
arrangement under which Vicor and Reltec Corporation entered into a license
agreement and agreed to settle all pending litigation and disputes relating to
Reltec's past use of certain Vicor intellectual property. In consideration for
the license under the Company's reset patents, and the separate settlement of
the litigation, Reltec made a one-time payment of $22.5 million into an escrow
account. Vicor is obligated to make know-how and technical support available to
Reltec under the license and will receive and recognize income from the escrow
fund through the first quarter of 2001.

In June 1998, the Company and VLT Corporation (which has since merged with
and into VLT, Inc.) filed a lawsuit in the United States District Court of
Massachusetts alleging that Unitrode Corporation ("Unitrode") has infringed and
is infringing U.S. Reissue Patent No. 36,098 (the "'Reset Patent") entitled
"Optimal Resetting of the Transformer's Core in Single Ended Forward
Converters." The Reset Patent is a reissue of U.S. Patent No. 4,441,146, which
issued on April 3, 1984. On January 24, 2001, the Court issued a summary
judgment decision in which the Court concluded that the Reset Patent is not
anticipated by certain prior art. The Court further concluded that the Reset
Patent is not invalid for failure to disclose the best mode of practicing the
invention nor is it invalid for indefiniteness. Finally, the Court concluded
that certain single-ended forward converters built by Unitrode, Siemens Corp.,
Lucent Technologies, Inc. ("Lucent"), Artesyn Technologies Inc., and Magnetek
Inc. infringed the Reset Patent. The Court declined to rule on certain other
matters relating to the Reset Patent, and a jury trial is scheduled to begin on
April 23, 2001.

In May 2000, the Company and VLT Corporation filed a lawsuit in the United
States District Court of Massachusetts alleging that Lucent has infringed and is
infringing the Reset Patent.

In February 2001, the Company and VLT, Inc. filed a lawsuit in the United
States District Court of Massachusetts alleging that Power-One Inc.
("Power-One") has infringed and is infringing the Reset Patent.

In March 2001, the Company and VLT, Inc. filed separate lawsuits in the
United States District Court of Massachusetts against Magnetek Inc., Siemens
Corp. and Siemens Medical Systems, Inc., a wholly-owned subsidiary of Siemens
Corp., alleging that these companies have infringed and are infringing the Reset
Patent.

The Company is in the process of enforcing its rights against other third
parties that it believes are infringing the Company's intellectual property.

The Company is involved in certain litigation incidental to the conduct of
its business. While the outcome of lawsuits against the Company cannot be
predicted with certainty, management does not expect any current litigation to
have a material adverse impact on the Company (see "Item 1 - Business -
Licensing" above).

Year Ended December 31, 2000 Compared to Year Ended December 31, 1999:

Net revenues for fiscal 2000 were $257,583,000, an increase of $67,696,000
(35.7%) as compared to $189,887,000 for fiscal 1999. The growth in revenues
resulted primarily from a net increase in unit shipments of standard and custom
products of approximately $73,403,000, which was offset by a decrease in license
revenue of approximately $5,707,000. The decrease in license revenue was
primarily due to non-recurring payments from licensees for past use of Vicor's
intellectual property in 1999. Although net revenues increased substantially in
fiscal 2000, the Company experienced a reduction in demand for its
first-generation products in the fourth quarter of 2000 which has continued in
early 2001. Shipments of second-generation products approximately doubled in
2000 versus 1999 and have continued to increase in early 2001. Both first and
second-generation products are sold to similar customers.

Gross margin increased $28,568,000 (35.2%) from $81,184,000 to
$109,752,000, and decreased as a percentage of net revenues from 42.8% to 42.6%.
The primary component of the increase in gross margin dollars was an increase in
net revenues. The primary components of the decrease in gross margin percentage
were an increase in depreciation on the second-generation automated production
line of approximately $1,300,000 in 2000 and changes in the revenue mix. These
items were offset by the increase in net revenues The Company continues to
refine the designs, processes, equipment and parts associated with
second-generation products. Until the Company achieves higher production
volumes, higher yield levels and attains component cost reductions on
second-generation products, gross margins will continue to be adversely
affected.

Selling, general, and administrative expenses were $43,179,000 for the
year, an increase of $6,348,000 (17.2%) over fiscal 1999. As a percentage of net
revenues, selling, general and administrative expenses decreased from 19.4% to
16.8%. The principal components of the $6,348,000 increase were $2,037,000
(43.2%) of increased sales commissions costs, $1,802,000 (14.3%) of increased
compensation expense, $1,161,000 (45.4%) of increased marketing program costs
and $756,000 (69.1%) of increased legal fees. The increase in marketing program
costs were due to an increase in space advertising and direct mail to support
new product introductions and increased international marketing expense.

Research and development expenses increased $637,000 (3.2%) to
$20,563,000, and decreased as a percentage of net revenues to 8.0% from 10.5%.
The principal components of the $637,000 increase were $1,314,000 (12.8%) of
increased compensation expense, $249,000 (26.8%) of increased research and
development costs associated with the operations of the Vicor Integrated
Architects ("VIA's") and $198,000 (102.6%) of increased temporary labor and
personnel expenses. The principle component offsetting the above increase was
$1,286,000 (35.3%) of decreased project material costs. The Company has a
long-term commitment to reinvesting its profits in new product design and
development in order to maintain and improve its competitive position.

Other income increased $347,000 (10.1%) to $3,786,000. Other income is
primarily comprised of interest income derived from invested cash and cash
equivalents and short-term investments, as well as a note receivable associated
with the Company's real estate transaction, as described in Note 5 to the
financial statements. Other income increased primarily due to an increase in
interest income due to an increase in cash and cash equivalents balances and
short-term investments and an increase in average interest rates, partially
offset by write-downs of $513,000 for certain equipment no longer in use.

Income before income taxes was $49,796,000, an increase of $21,930,000
(78.7%) compared to 1999. As a percentage of net revenues, income before income
taxes increased from 14.7% in 1999 to 19.3% in 2000.

The provision for income taxes totaled $15,876,000 in 2000 compared to
$8,778,000 in 1999. The Company's overall tax rate was 31.9% and 31.5% for 2000
and 1999, respectively. The increase in the effective tax rate was due to the
reduced impact of tax credits in 2000 on a higher level of income before income
taxes. On a preliminary basis, the effective tax rate is expected to increase to
between 36.0% and 37.5% in 2001, due to a reduced amount of available tax
credits.

Net income in 2000 increased by $14,832,000 to $33,920,000. Diluted
earnings per share were $.78 in 2000 compared to $.45 in 1999.


11
Year Ended December 31, 1999 Compared to Year Ended December 31, 1998:

Net revenues for fiscal 1999 were $189,887,000, an increase of $25,253,000
(15.3%) as compared to $164,634,000 for fiscal 1998. The growth in revenues
resulted primarily from a net increase in unit shipments of standard and custom
products of approximately $14,750,000 and an increase in license revenue of
approximately $10,500,000. The increase in license revenue was primarily due to
non-recurring payments from licensees for past use of Vicor's intellectual
property.

Gross margin increased $7,235,000 (9.8%) from $73,949,000 to $81,184,000,
and decreased as a percentage of net revenues from 44.9% to 42.8%. The primary
components of the increase in gross margin dollars were an increase in net
revenues and changes in the revenue mix. The primary components of the decrease
in gross margin percentage were an increase in depreciation on the
second-generation automated production line of approximately $1,647,000 in 1999,
changes in the revenue mix and a non-recurring charge of $700,000 in the first
quarter of 1999 for exit costs in connection with the relocation of certain
manufacturing operations from a leased facility to the Company's owned
manufacturing facility at Federal Street in Andover, Massachusetts. These items
were offset by the increase in net revenues.

Selling, general, and administrative expenses were $36,831,000 for the
year, an increase of $1,897,000 (5.4%) over fiscal 1998. As a percentage of net
revenues, selling, general and administrative expenses decreased from 21.2% to
19.4%. The principal components of the $1,897,000 increase were $2,290,000
(176.6%) of increased selling, general and administrative expenses incurred by
Vicor Japan Company Ltd. ("VJCL"), which began operations in July 1998, $894,000
of payroll tax expense associated with the exercise of stock options, $710,000
(38.1%) of increased depreciation and amortization expense and $460,000 (43.6 %)
of increased facility costs. The principle components offsetting the above
increase were $1,382,000 (35.1%) of decreased advertising costs and $978,000
(47.2%) of decreased legal expenses. The decrease in advertising costs were due
to a reduction in the use of printed materials and lower international
advertising expense. Legal expense, in the third quarter of 1998, included
approximately $700,000 of legal costs incurred in connection with intellectual
property litigation.

Research and development expenses decreased $724,000 (3.5%) to
$19,926,000, and decreased as a percentage of net revenues to 10.5% from 12.5%.
The principal components of the $724,000 decrease were $2,404,000 (19.1%) of
decreased compensation expense in the research and development departments due
to these departments transitioning from research and development to
manufacturing costs centers. These cost centers are charged to cost of sales and
are primarily related to the second-generation automated production line. The
principle components offsetting the above decrease were $895,000 (32.6%) of
increased project material costs, $574,000 (106.4%) of increased research and
development costs associated with VJCL and $299,000 (47.5%) of increased
research and development costs associated with the operations of the VIA's.

Other income decreased $1,483,000 (30.1%) to $3,439,000. Other income is
primarily comprised of interest income which was derived from invested cash and
cash equivalents, as well as a note receivable associated with the Company's
real estate transaction. Interest income decreased primarily due to a decrease
in the average rates from 1998 to 1999.

Income before income taxes was $27,866,000, an increase of $4,579,000
(19.7%) compared to 1998. As a percentage of net revenues, income before income
taxes increased from 14.1% in 1998 to 14.7% in 1999.

The provision for income taxes totaled $8,778,000 in 1999 compared to
$7,452,000 in 1998. The Company's overall tax rate was 31.5% and 32.0% for 1999
and 1998, respectively. The decrease in the effective tax rate was due to the
impact of expected tax credits in 1999.

Net income in 1999 increased by $3,253,000 to $19,088,000. Diluted
earnings per share were $.45 in 1999 compared to $.37 in 1998.


12
LIQUIDITY AND CAPITAL RESOURCES

At December 31, 2000, the Company had $62,916,000 in cash and cash
equivalents. Working capital increased $23,461,000 during the year ended
December 31, 2000. This increase was due primarily to higher earnings in 2000,
an increase in accounts receivable and inventories of $27,353,000 and an
increase in short-term investments of $5,600,000, offset by a decrease in cash
of $6,193,000 and an increase in income taxes payable of $3,712,000.

Cash used in investing activities during fiscal 2000 was $22,353,000, an
increase of $6,660,000 (42.4%) compared to fiscal 1999. This increase was
primarily due to an increase in net additions to property and equipment of
$1,956,000 and a net increase in short-term investments of $5,600,000. Cash used
in financing activities was $22,529,000 compared to cash provided by financing
activities of $9,498,000 in 1999, a net change of $32,027,000. This change is
primarily attributed to a net increase in the acquisition cost of treasury stock
of $24,425,000 in 2000, and a decrease in the net proceeds from the issuance of
Common Stock upon the exercise of stock options of $7,602,000.

The Company's primary liquidity needs are for making continuing
investments in manufacturing equipment, much of which is built internally,
particularly for the Company's second-generation products. The internal
construction of manufacturing machinery, in order to provide for additional
manufacturing capacity, is a practice which the Company expects to continue over
the next several years. The Company is taking steps to increase the capacity of
second-generation manufacturing, which includes adding equipment and
re-deploying personnel and equipment from first-generation production. In
February 2001, management approved approximately $16 million in new capital
expenditures to execute this plan.

In February 2000, the Board of Directors of the Company authorized the
repurchase of up to $30,000,000 of the Company's Common Stock (the "February
2000 Plan"). The February 2000 Plan authorizes the Company to make such
repurchases from time to time in the open market or through privately negotiated
transactions. The timing of this program and the amount of the stock that may be
repurchased is at the discretion of management based on its view of economic and
financial market conditions. In 2000, the Company spent $32,989,000 for the
repurchase of shares of its Common Stock under the February 2000 Plan and a
prior repurchase plan.

In November 2000, the Board of Directors of the Company authorized the
repurchase of up to an additional $30,000,000 of the Company's Common Stock,
under terms similar to those of the February 2000 Plan.

The Company believes that cash generated from operations and its cash and
cash equivalents will be sufficient to fund planned operations and capital
equipment purchases for the foreseeable future. At December 31, 2000, the
Company had approximately $500,000 of capital expenditure commitments.

The Company does not consider the impact of inflation and changing prices
on its business activities or fluctuations in the exchange rates for foreign
currency transactions to have been material during the last three fiscal years.

ITEM 7(a) QUALITATIVE AND QUANTITATIVE DISCLOSURE ABOUT MARKET RISK

The Company is exposed to a variety of market risks, including changes in
interest rates affecting the return on its cash and cash equivalents and
fluctuations in foreign currency exchange rates. The Company's exposure to
market risk for a change in interest rates relates primarily to the Company's
cash and cash equivalents and short-term investments.

As the Company's cash and cash equivalents consist principally of money
market securities, which are short-term in nature, the Company's exposure to
market risk on interest rate fluctuations is not significant. The Company's
exposure to market risk for fluctuations in foreign currency exchange rates
relates primarily to the operations of VJCL. The Company believes that this
market risk is currently not material due to the relatively small size of VJCL's
operations.

VICOR CORPORATION
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. SIGNIFICANT ACCOUNTING POLICIES

Description of business

Vicor Corporation (the "Company") designs, develops, manufactures and
markets modular power converters, power system components, and power systems
using a patented, high frequency power conversion technology designated "zero
current switching." The Company also licenses certain rights to its technology
in return for ongoing royalties. The principal markets for the power converters
and systems are large Original Equipment Manufacturers and smaller, lower volume
users which are broadly distributed across several major market areas.

Principles of consolidation

The consolidated financial statements include the accounts of the Company
and its subsidiaries. All intercompany transactions and balances have been
eliminated upon consolidation.

Revenue recognition

Product revenue is recognized in the period when persuasive evidence of an
arrangement with a customer exists, the products are shipped and title has
transferred to the customer, the price is fixed and determinable, and collection
is considered probable. License fees are recognized ratably over the period of
exclusivity or as additional royalty payments would have been required, if
greater, or over the period in which the Company provides services. The Company
recognizes revenue on such arrangements only when the contract is signed, the
license term has begun, all obligations have been delivered to the customer, and
collection is probable. During the year, the Company evaluated the provisions of
Staff Accounting Bulletin (SAB) No. 101, "Revenue Recognition in Financial
Statements." There was no cumulative effect associated with implementing SAB
101.

Foreign currency translation

The financial statements of Vicor Japan Company, Ltd. ("VJCL"), for which
the functional currency is the Japanese yen, have been translated into U.S.
dollars in accordance with FASB Statement No. 52, "Foreign Currency
Translation". All balance sheet accounts have been translated using the exchange
rate in effect at the balance sheet date. Income statement amounts have been
translated at the average exchange rates in effect during the year. The gains
and losses resulting from the changes in exchange rates from year to year have
been reported in other comprehensive income. The effect on the statements of
income of transaction gains and losses is insignificant for all years presented.

Cash and cash equivalents

Cash and cash equivalents include funds held in checking and money market
accounts with banks, certificates of deposit and debt securities with maturities
of less than three months when purchased and money market securities. Cash and
cash equivalents are valued at cost which approximates market value. The
Company's money market securities, which are classified as cash equivalents on
the balance sheet, are purchased and redeemed at par. The estimated fair value
is equal to the cost of the securities and due to the nature of the securities
there are no unrealized gains or losses at the balance sheet dates. As of
December 31, 2000, the Company has approximately $52 million of
available-for-sale securities included in cash and cash equivalents ($58 million
as of December 31, 1999).

Short-term investments

The Company's short-term investments are classified as available for sale
securities, and the fair value approximates the cost of the securities. These
investments consist of corporate bonds with original maturities of greater than
three months when purchased. As of December 31, 2000, these bonds have remaining
maturities between 18 months and 2 years. The Company considers these
investments, which represent funds for current operations, to be an integral
part of its cash management activities. The Company has no trading securities or
held-to-maturity securities.

1. SIGNIFICANT ACCOUNTING POLICIES (Continued)

Concentrations of credit risk

Financial instruments that potentially subject the Company to significant
concentrations of credit risk consist principally of cash and cash equivalents,
short-term investments and trade accounts receivable. The Company maintains cash
and cash equivalents and certain other financial instruments with various high
credit, quality financial institutions. Concentrations of credit risk with
respect to trade accounts receivable are limited due to the large number of
entities comprising the Company's customer base. Credit losses have consistently
been within management's expectations and have not been material.

Intangible Assets

Intangible assets, which are included in the other assets in the
accompanying balance sheets, consist primarily of values assigned to patents and
to the excess of cost over the assigned value of net assets acquired. Intangible
assets are amortized using the straight-line method over periods ranging from
five to fifteen years. Amortization expense was approximately $1,057,000,
$929,000 and $536,000 in 2000, 1999 and 1998, respectively. Accumulated
amortization was $2,585,000 at December 31, 2000 and $1,924,000 at December 31,
1999.

Long-lived assets, such as these intangible assets, are included in
impairment evaluations when events or circumstances exist that indicate the
carrying amount of those assets may not be recoverable. If the impairment
evaluation indicates the affected asset is not recoverable, the asset's carrying
value would be reduced to fair value. No event has occurred that would impair
the value of long-lived assets recorded in the accompanying consolidated
financial statements.

Advertising expense

The cost of advertising is expensed as incurred. The Company incurred
$3,506,000, $2,189,000, and $3,197,000 in advertising costs during 2000, 1999
and 1998, respectively.

Net income per common share

Basic and diluted income per share are calculated in accordance with FASB
Statement No. 128, "Earnings per Share."

Use of estimates

The preparation of the financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.

Comprehensive income

The Company reports comprehensive income in accordance with FASB Statement
No. 130, "Reporting Comprehensive Income." Statement No. 130 requires the
foreign currency translation adjustments related to VJCL to be included in other
comprehensive income.

Impact of recently issued accounting standards

In June 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 133, (FAS 133), "Accounting for Derivative
Instruments and Hedging Activities", which required adoption in periods
beginning after June 15, 1999. FAS 133 was subsequently amended by FAS 137,
"Accounting for Derivative Instruments and Hedging Activities - Deferral of the
Effective Date of FASB Statement No. 133" and will now be effective for fiscal
years beginning after June 15, 2000, with earlier adoption permitted. The
Company will adopt FAS 133 on a cumulative basis during fiscal 2001, as
required. The Company does not expect the adoption of FAS 133 to have a
significant impact on its financial position or the results of operations.

2. ACQUISITION

Effective July 1, 1998, the Company and its wholly-owned subsidiary VJCL
acquired the principal assets of the switching power supply businesses owned by
the Japan Tobacco, Inc. Group ("JT"). The assets acquired included automated
manufacturing equipment, existing raw material and finished goods inventories,
customer lists and certain intellectual property. VJCL also assumed certain
warranty obligations for products manufactured by JT prior to the acquisition
date and for a six month transition period ending December 31, 1998. The
acquisition was accounted for by the purchase method. The total value of
consideration given and liabilities assumed aggregated $19.1 million. In
addition to cash payments for inventories, the Company paid for the automated
equipment in three equal installments of $5.3 million through December 31, 1999.
The total cost of the purchase in excess of the net assets acquired of
approximately $3.2 million, including final purchase accounting adjustments
recorded during 1999, is being amortized over ten years.

The following unaudited pro forma financial information for the years
ended December 31, 1998 assumes the acquisition occurred as of January 1, 1998
(in thousands, except per share amounts):

1998
----

Net revenues $173,421
Net income $14,216
Net income per share-diluted $ 0.33

The pro forma financial information is not necessarily indicative of the
operating results that would have occurred had the acquisition been completed as
of January 1, 1998, nor are they necessarily indicative of future operating
results.

3. INVENTORIES

Inventories are valued at the lower of cost (determined using the
first-in, first-out method) or market. Inventories were as follows (in
thousands):

4. PROPERTY, PLANT AND EQUIPMENT

Property, plant and equipment are stated at cost and are depreciated and
amortized over a period of 3 to 31.5 years generally under the straight-line
method for financial reporting purposes and accelerated methods for income tax
purposes. Property, plant and equipment were as follows (in thousands):

December 31
2000 1999
---- ----

Land $ 2,089 $ 2,089
Buildings and improvements 36,203 36,321
Machinery and equipment 136,258 122,749

Less accumulated depreciation and amortization 83,777 66,831
-------- --------
$107,807 $109,079
======== ========

During 2000, the Company had write-downs of approximately $513,000 for
certain equipment no longer in use, which was included in other income in the
accompanying consolidated statements of income.

At December 31, 2000, the Company had approximately $500,000 of capital
expenditure commitments.

5. NOTES RECEIVABLE

In May 1997, the Company received a promissory note in the amount of
$7,500,000 from an unrelated third party in exchange for $5,000,000 in cash plus
the termination of an existing note in the amount of $2,500,000. The note bears
interest at 9% and is due in May 2002. The note is secured by a mortgage on
certain real estate and by the assignment of certain leases and other contracts.

The Company's President has borrowed funds from the Company pursuant to a
series of unsecured term notes. The notes have terms of five years and are due
at various dates through November 2005. The notes bear interest at the higher of
the Company's prime borrowing rate less 1%, or the applicable federal rate under
the Internal Revenue Code of 1986, as amended. As of December 31, 2000, the
notes and interest receivable balance was approximately $1,600,000 ($1,300,000
as of December 31, 1999) and the applicable interest rate at December 31, 2000
was 8.50% (7.50% at December 31, 1999).

6. STOCKHOLDERS' EQUITY

In February 2000, the Board of Directors of the Company authorized the
repurchase of up to $30,000,000 of the Company's Common Stock (the "February
2000 Plan"). The plan authorizes the Company to make such repurchases from time
to time in the open market or through privately negotiated transactions. The
timing of this program and the amount of the stock that may be repurchased is at
the discretion of management based on its view of economic and financial market
conditions. In 2000, the Company spent $32,989,000 in the repurchase of its
Common Stock under the February 2000 Plan and a prior repurchase plan.

In November 2000, the Board of Directors of the Company authorized the
repurchase of up to an additional $30,000,000 of the Company's Common Stock,
under terms similar to those of the February 2000 Plan.

VICOR CORPORATION
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

6. STOCKHOLDERS' EQUITY (Continued)

Common Stock

Each share of Common Stock entitles the holder thereof to one vote on all
matters submitted to the stockholders. Each share of Class B Common Stock
entitles the holder thereof to ten votes on all such matters.

Shares of Class B Common Stock are not transferable by a stockholder
except to or among such stockholder's spouse, certain of such stockholder's
relatives, and certain other defined transferees. Class B Common Stock is not
listed or traded on any exchange or in any market. Class B Common Stock is
convertible at the option of the holder thereof at any time and without cost to
the stockholder into shares of Common Stock on a one-for-one basis.

During 2000, a total of 879,222 shares of Common Stock were issued upon
the exercise of stock options, and 73,659 shares of Class B Common Stock were
converted into 73,659 shares of Common Stock.

7. INCOME PER SHARE

The following table sets forth the computation of basic and diluted income
per share (in thousands, except per share amounts):

<TABLE>

Basic income per share $ .80 $ .46 $ .37
======= ======= =======

Diluted income per share $ .78 $ .45 $ .37
======= ======= =======
</TABLE>

Options to purchase 15,730 shares of Common Stock were outstanding during
2000 (none in 1999 and 663,587 in 1998) but were not included in the computation
of diluted income per share because the options' exercise prices were greater
than the average market price of the Common Stock and, therefore, the effect
would have been antidilutive.

8. EMPLOYEE BENEFIT PLANS

Stock Options

The Company has elected to follow Accounting Principles Board Opinion No.
25, "Accounting for Stock Issued to Employees" (APB 25) and related
Interpretations in accounting for its employee stock options because, as
discussed below, the alternative fair value accounting provided for under FASB
Statement No. 123, "Accounting for Stock-Based Compensation," requires use of
option valuation models that were not developed


25
VICOR CORPORATION
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

8. EMPLOYEE BENEFIT PLANS (Continued)

for use in valuing employee stock options. Under APB 25, because the exercise
price of the Company's employee stock options equals the market price of the
underlying stock on the date of grant, no compensation expense is recognized.

Under the Company's 2000 Stock Option and Incentive Plan (the "2000
Plan"), the Board of Directors or the Compensation Committee may grant certain
stock incentive awards based on the Company's Common Stock, including stock
options, stock appreciation rights, restricted stock, performance shares,
unrestricted stock, deferred stock and dividend equivalent rights. Awards may be
granted to employees and other key persons, including non-employee directors.
Incentive stock options may be granted to employees at a price at least equal to
the fair market value per share of the Common Stock on the date of grant, and
non-qualified options may be granted to non-employee directors at a price at
least equal to 85% of the fair market value of the Common Stock on the date of
grant. A total of 2,000,000 shares of Common Stock have been reserved for
issuance under the 2000 Plan. The period of time during which an option may be
exercised and the vesting periods will be determined by the Compensation
Committee. The term of each option may not exceed ten years from the date of
grant.

Under the Company's 1998 Stock Option and Incentive Plan (the "1998
Plan"), the Board of Directors or the Compensation Committee may grant certain
stock incentive awards based on the Company's Common Stock, including stock
options, stock appreciation rights, restricted stock, performance shares,
unrestricted stock, deferred stock and dividend equivalent rights. Awards may be
granted to employees and other key persons, including non-employee directors.
Incentive stock options may be granted to employees at a price at least equal to
the fair market value per share of the Common Stock on the date of grant, and
non-qualified options may be granted to non-employee directors at a price at
least equal to 85% of the fair market value of the Common Stock on the date of
grant. A total of 2,000,000 shares of Common Stock have been reserved for
issuance under the 1998 Plan. The period of time during which an option may be
exercised and the vesting periods will be determined by the Compensation
Committee. The term of each option may not exceed ten years from the date of
grant.

Under the 1993 Stock Option Plan (the "1993 Plan"), the Board of Directors
or the Compensation Committee may grant stock options to employees and
non-employee directors to purchase shares of Common Stock at a price at least
equal to the fair market value per share of the outstanding Common Stock at the
time the option is granted. Both incentive stock options intended to qualify
under Section 422 of the Internal Revenue Code and non-qualified stock options
have been authorized to be granted. Incentive stock options may be granted to
employees, including employees who are directors of the Company, and
non-qualified options may be granted to non-employee directors. Both employee
directors and non-employee directors automatically receive stock options upon
election or re-election as a director. A total of 4,000,000 shares of Common
Stock have been reserved for issuance under the 1993 Plan. Stock options are
typically granted with vesting periods and become exercisable over various
periods of time, ranging from six months to five years from the date of grant,
and expire over various periods of time, ranging from one to ten years from the
date of grant.

Under the Company's 1984 Stock Option Plan, as amended (the "1984 Plan"),
the Board of Directors or the Compensation Committee granted stock options to
employees to purchase shares of Common Stock at a price at least equal to the
fair market value per share of the outstanding Common Stock at the time the
option was granted. Stock options under the 1984 Plan were typically granted
with vesting periods and became exercisable over various periods of time,
ranging from six months to five years from the date of grant, and expire over
various periods of time, ranging from one to thirteen years from the date of
grant. In connection with the adoption of the 1993 Plan, the Board of Directors
terminated the granting of options under the 1984 Plan upon approval of the 1993
Plan, discussed above.

Pro forma information regarding net income and earnings per share is
required by Statement No. 123, which also requires that the information be
determined as if the Company had accounted for its employee stock options
granted subsequent to December 31, 1994 under the fair value method described in
that Statement. The fair value for these options was estimated at the date of
grant using a Black-Scholes option pricing model with the following
weighted-average assumptions for 2000, 1999 and 1998, respectively: risk-free
interest rates of 6.1%, 5.4% and 5.3%; dividend yields of zero; volatility
factor of the expected market price of the Company's common stock of .59, .55
and .55; and a weighted-average expected life of the option of 4.4, 3.3 and 3.4
years.

The Black-Scholes option valuation model was developed for use in
estimating the fair value of traded options which have no vesting restrictions
and are fully transferable. In addition, option valuation models require the
input of highly subjective assumptions including the expected stock price
volatility. Because the Company's employee stock options have characteristics
significantly different from those of traded options, and because changes in the
subjective input assumptions can materially affect the fair value estimate, in
management's opinion, the existing models do not necessarily provide a reliable
single measure of the fair values of its employee stock options.

For purposes of pro forma disclosures, the estimated fair value of the
options is amortized to expense over the options' vesting period. The Company's
pro forma information follows (in thousands except for earnings per share
information):

The effects on 2000, 1999 and 1998 pro forma net income and net income per
share of expensing the fair value of stock options issued are not necessarily
representative of the effects on reporting the pro forma results of operations
for future years as the periods presented include only six, five and four years,
respectively, of option grants under the Company's plans.

401(k) Plan

The Company sponsors a savings plan available to all domestic employees
which qualifies under Section 401(k) of the Internal Revenue Code. Employees may
contribute to the plan from 1% to 20% of their pre-tax salary subject to
statutory limitations. Beginning October 1, 2000, the Company began to match
employee contributions to the plan at a rate of 50% up to the first 3% of an
employee's contribution. The Company's matching contributions currently vest at
a rate of 20% per year based upon years of service. The Company's contribution
to the plan was approximately $176,000 in 2000.

Stock Bonus Plan

Under the Company's 1985 Stock Bonus Plan, as amended, shares of Common
Stock may be awarded to employees from time to time as determined by the Board
of Directors. At December 31, 2000, 109,964 shares were available for further
award. All shares awarded to employees under this plan have vested. No further
awards are contemplated under this plan at present.

10. COMMITMENTS AND CONTINGENCIES

The Company leases certain of its office, warehousing and manufacturing
space, as well as certain equipment. The future minimum rental commitments under
noncancelable operating leases with remaining terms in excess of one year are as
follows (in thousands):

Year
- ----
2001 $1,102
2002 881
2003 584
2004 524
2005 310

Rent expense was approximately $1,028,000, $1,146,000, and $1,534,000 in
2000, 1999 and 1998, respectively. The Company also pays executory costs such as
taxes, maintenance and insurance.

The Company has a contract with a third-party to supply nitrogen for its
manufacturing and research and development activities. Under the contract, the
Company is obligated to pay a minimum of $250,000 annually, subject to
semi-annual price adjustments, through 2015.

The Company is involved in certain litigation incidental to the conduct of
its business. While the outcome of lawsuits against the Company cannot be
predicted with certainty, management does not expect any current litigation to
have a material adverse effect on the Company.

11. SEGMENT INFORMATION

The Company operates in one industry segment: the development, manufacture
and sale of power conversion components and systems. During 2000, 1999 and 1998,
no customer accounted for more than 10% of net revenues. Export sales, as a
percentage of total revenue, were approximately 32%, 30%, and 29% in 2000, 1999
and 1998, respectively. Export sales and receipts are recorded and received in
U.S. dollars. Foreign exchange fluctuations have not been material to the
Company's operating results during the last three years.

12. LICENSE AGREEMENT AND LITIGATION SETTLEMENT

On February 1, 1999, the Company and Reltec Corporation ("Reltec") entered
into a license agreement under which Reltec acquired a non-exclusive, worldwide
license to use Vicor's patented "reset" technology. Concurrently, the Company
and Reltec agreed to settle all pending litigation and disputes relating to
Reltec's past use of certain Vicor intellectual property. In consideration for
the license and the separate settlement of the litigation, Reltec made a
one-time payment of $22.5 million into an escrow fund. Vicor is obligated to
make know-how and technical support available to Reltec under the license and
will receive and recognize income from the escrow fund through the first quarter
of 2001.
