      in the Company's audited financial statements for the year ended December

4. COMPREHENSIVE INCOME

      Total comprehensive income (loss) was ($4,125,000) and ($9,711,000) for
      the three and six months ended June 30, 2002, respectively, and ($706,000)
      and $955,000 for the three and six months ended June 30, 2001,
      respectively. Other comprehensive income (loss) consisted principally of
      adjustments for foreign currency translation gains in the amounts of
      $110,000 and $103,000 and unrealized gains (losses) on available for sale
      securities in the amount of $617,000 and ($31,000) for the three and six
      months ended June 30, 2002, respectively.

5. IMPACT OF RECENTLY ISSUED ACCOUNTING STANDARDS

      In July 2001, the Financial Accounting Standards Board ("FASB") issued
      Statement of Financial Accounting Standards No. 142 (FAS 142) "Goodwill
      and Other Intangible Assets." Under FAS 142, goodwill and indefinite lived
      intangible assets will no longer be amortized but will be tested for
      impairment at least annually at the reporting unit level. The Company
      adopted FAS 142 in the first quarter of 2002, which resulted in the
      elimination of goodwill amortization beginning in fiscal 2002. In the
      quarter ended June 30, 2002 as provided for in FAS 142, the Company
      performed the first of the required tests under FAS 142 with respect to
      its goodwill of approximately $2,000,000 related to the operations of one
      of its subsidiaries, Vicor Japan Company, Ltd. ("VJCL"), and has
      determined that there is no impairment to the carrying value of this
      goodwill. The Company has no other goodwill or acquired intangible assets
      on the balance sheet at June 30, 2002.

      In June 2001, the FASB issued Statement of Financial Accounting Standards
      No. 143 (FAS 143) "Accounting for Asset Retirement Obligations," which
      addresses financial accounting and reporting for obligations associated
      with the retirement of tangible long-lived assets and the associated asset
      retirement costs. It also applies to legal obligations associated with
      retirement of long-lived assets that result from the acquisition,
      construction, development and/or the normal operation of a long-lived
      asset except for certain obligations of lessees. The Company is required
      to adopt FAS 143 in the first quarter of 2003 and does not expect it will
      have a material effect on the Company's financial position or results of
      operations.

      In October 2001, the FASB issued Statement of Financial Accounting
      Standards No. 144 (FAS 144) "Accounting for the Impairment or Disposal of
      Long-Lived Assets." FAS 144 supersedes FAS 121, "Accounting for the
      Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed
      Of" and provides a single accounting model for long-lived assets to be
      disposed of. The Company adopted FAS 144 in the first quarter of 2002. The
      adoption of FAS 144 did not have a significant impact on the Company's
      financial statements.

RESULTS OF OPERATIONS

THREE MONTHS ENDED JUNE 30, 2002 COMPARED TO THREE MONTHS ENDED JUNE 30, 2001

Net revenues for the second quarter of 2002 were $36,831,000, a decrease of
$13,429,000 (26.7%) as compared to $50,260,000 for the same period a year ago.
The decrease in net revenues resulted primarily from a decrease in unit
shipments of standard and custom products of approximately $12,729,000 and a
decrease in license revenue of $700,000. Management believes that the decrease
in unit shipments and net revenues is primarily due to infrastructure
over-capacity in the major electronic markets, particularly in the
communications markets. As a result, demand for the Company's products suffered
in 2001 and the first six months of 2002. While the Company has experienced an
increase in orders in the first half of 2002 as compared with the second half of
2001, they are still significantly less than that of 2000 and the first half of
2001. There can be no assurance that these increases will continue. The
book-to-bill ratio was 1.01 for the second quarter of 2002 compared to 0.75 for
the same period a year ago.

Gross margin for the second quarter of 2002 decreased $5,532,000 (38.9%) to
$8,683,000 from $14,215,000, and decreased as a percentage of net revenues from
28.3% to 23.6%. The primary components of the decreases in gross margin dollars
and percentage were the decrease in net revenues and changes in the revenue mix,
principally due to the decrease in license revenue, partially offset by
additional provisions for inventory reserves for potential excess raw materials
taken in the second quarter of 2001. The Company continues to refine the design,
processes, equipment and parts associated with second-generation products. Until
the Company achieves higher production volumes for both its first- and
second-generation products and attains higher yield levels and component cost
reductions on second-generation products, gross margins will continue to be
adversely affected.



                                                                       FORM 10-Q

                     Management's Discussion and Analysis of
                  Financial Condition and Results of Operations
                                  June 30, 2002
                                   (continued)


Selling, general and administrative expenses were $11,134,000 for the period, a
decrease of $208,000 (1.8%) over the same period in 2001. As a percentage of net
revenues, selling, general and administrative expenses increased to 30.2% from
22.6% primarily due to the reduction in net revenues. The principal components
of the $208,000 decrease were $363,000 (27.5%) of decreased sales commission
costs due to decreased product sales, $124,000 (15.2%) of decreased costs
associated with the operations of VJCL, principally due to reduced compensation
and transportation expenses, and $112,000 (12.2%) of decreased advertising
expenses. The principal components offsetting the above decreases were an
increase of $252,000 (17.7%) in legal expenses related to the Company's patent
infringement actions (see Part II, Item 1 - "Legal Proceedings") and a $179,000
(4.6%) increase in compensation expense. The increase in compensation expense
was primarily due to the completion in the first quarter of 2002 of the
internally developed software project of the Company's new Enterprise Resource
Planning System. In accordance with Statement of Position 98-1, "Accounting for
the Costs of Computer Software Developed or Obtained for Internal Use," certain
costs associated with this project were capitalized and capitalization ceased
upon completion.

Research and development expenses decreased $204,000 (3.8%) to $5,128,000, but
increased as a percentage of net revenues to 13.9% from 10.6% due to the
reduction in net revenues. The principal components of the $204,000 decrease
were $276,000 (46.9%) of decreased project materials costs, $110,000 (80.1%) of
decreased personnel expenses, principally for employment recruiting,
advertisement and relocation expenses, and a decrease of $97,000 (3.0%) of
compensation expense. This was offset by $277,000 (342.0%) of increased
development costs associated with the automation and test engineering groups.
Approximately $524,000 of the net decrease in compensation expense was due to
certain manufacturing engineering groups being transferred to operations in the
third quarter of 2001 where they are included in cost of sales. This decrease
was partially offset by increases in other engineering groups, in particular at
the Company's Picor subsidiary, which increased by $326,000. The Company has a
long-term commitment to investing in new product design and development in order
to maintain and improve its competitive position.

Under the Company's previously announced cost reduction plan, the Company
continues to require a reduced work schedule for direct factory employees, as
required by production demands, and mandatory use of certain accrued personal
time by all other employees. The need for this plan is reviewed by senior
management on a periodic basis.

Other income (expense), net decreased $981,000 (106.9%) from the same period a
year ago to ($63,000). 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
(which was repaid in May 2002) and foreign currency transaction gains or losses.
Other income (expense), net decreased due to a loss of $1,078,000 resulting from
a decline in the value of the Company's investment in Scipher, plc judged to be
other than temporary and a decrease in interest income of approximately $346,000
due to a decrease in average interest rates. These decreases were partially
offset by an increase in foreign currency transaction gains of $418,000.

The loss before income taxes was $7,642,000, an increase of $6,101,000 (395.9%)
compared to the loss before taxes of $1,541,000 for the same period in 2001.

The effective tax rate for the second quarter of 2002 was 36.5%, compared to
38.2% for the same period in 2001.

Diluted loss per share was ($.11) for the second quarter of 2002, compared to
($.02) for the second quarter of 2001.

SIX MONTHS ENDED JUNE 30, 2002 COMPARED TO SIX MONTHS ENDED JUNE 30, 2001

Net revenues for the first six months of 2002 were $71,451,000, a decrease of
$33,828,000 (32.1%) as compared to $105,279,000 for the same period a year ago.
The decrease in net revenues resulted primarily from a decrease in unit
shipments of standard and custom products of approximately $32,305,000 and a
decrease in license revenue of $1,523,000. The decrease in licensing revenue was
primarily due to recognition of the final amounts under the license agreement
with Reltec Corporation during the first quarter of 2001. The book-to-bill ratio
was 1.01 for the first six months of 2002 compared to 0.94 for the same period a
year ago.

Gross margin for the first half of 2002 decreased $15,185,000 (47.4%) to
$16,845,000 from $32,030,000 and decreased as a percentage of net revenues from
30.4% to 23.6%. The primary components of the decreases in gross margin dollars
and percentage were due to the decrease in net revenues and changes in the
revenue mix, principally due to the decrease in license revenue, partially
offset by additional provisions for inventory reserves for potential excess raw
materials in the first half of 2001.

Selling, general and administrative expenses were $21,387,000 for the period, a
decrease of $269,000 (1.2%) over the same period in 2001. As a percentage of net
revenues, selling, general and administrative expenses increased to 29.9% from
20.6% primarily due to the reduction in net revenues. The principal components
of the $269,000 decrease were $744,000 (27.8%) of decreased sales commission
costs due to decreased product sales, $403,000 (23.2%) of decreased advertising
costs, $176,000 (16.3%) of decreased costs associated with the operations of the
Vicor Integrated Architects ("VIAs") and $174,000 (11.5%) of decreased costs
associated with the operations of VJCL, principally due to reduced compensation
and transportation expenses. These were offset by a $1,349,000 (78.2%) increase
in legal costs related to the Company's patent infringement actions (see Part
II, Item 1 - "Legal Proceedings").

Research and development expenses decreased $550,000 (5.1%) to $10,235,000, but
increased as a percentage of net revenues to 14.3% from 10.2% due to the
reduction in net revenues. The principal components of the $550,000 decrease
were $331,000 (5.2%) of decreased compensation expense, $320,000 (28.2%) of
decreased project material costs and $250,000 (74.7%) of decreased personnel
expenses, principally for employment recruiting, advertising and relocation
expenses. These were offset by $478,000 (264.1%) of increased development costs
associated with the automation and test engineering groups. Approximately
$1,173,000 of the net decrease in compensation expense was due to certain
manufacturing engineering groups being transferred to operations in the third
quarter of 2001 where they are included in cost of sales. This decrease was
partially offset by increases in other engineering groups, in particular at the

                  Financial Condition and Results of Operations
                                  June 30, 2002

Other income (expense), net decreased $2,650,000 (131.2%) from the same period a
year ago, to ($630,000). 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
(which was repaid in May 2002) and foreign currency transaction gains or losses.
The decrease in other income (expense), net was due to the write-down of
obsolete equipment of $1,159,000, a loss of $1,078,000 resulting from a decline
in the value of the Company's investment in Scipher, plc judged to be other than
temporary and a decrease in interest income of approximately $957,000 due to a
decrease in average interest rates. These decreases were partially offset by an
increase in foreign currency transaction gains of $595,000.

Income (loss) before income taxes was $(15,407,000), a decrease of $17,016,000
compared to the same period in 2001.

The effective tax rate for the six months ended June 30, 2002 was 36.5%,
compared to 30.0% for the same period in 2001.

Diluted loss per share was $(0.23) for the six months ended June 30, 2002,
compared to diluted income per share of $.03 for the same period in 2001.

LIQUIDITY AND CAPITAL RESOURCES

At June 30, 2002 the Company had $68,957,000 in cash and cash equivalents. The
ratio of current assets to current liabilities was 10.5:1 at June 30, 2002
compared to 11.0:1 at December 31, 2001. Working capital decreased $3,151,000
from $153,159,000 at December 31, 2001 to $150,008,000 at June 30, 2002. The
primary factors affecting the working capital decrease were a decrease in a note
receivable of $7,500,000 and a decrease in inventories of $7,305,000, offset by
an increase in cash of $11,476,000. The primary sources of cash were a net
decrease in notes receivable of $7,461,000, $7,396,000 from operating activities
and net sales of short-term investments of $2,918,000. The primary use of cash
for the six months ended June 30, 2002 was for additions to property and
equipment of $6,173,000.

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 in the process of completing an upgrade to second-generation
products, internally designated as FastTrack, which the Company anticipates will
help to increase production capacity and reduce costs. In February 2001,
management approved approximately $16,000,000 in new capital expenditures to
execute this plan. The Company currently estimates that it will spend
approximately $12,000,000 under this plan. Through June 30, 2002, the Company
has spent approximately $10,700,000 under this plan, with the remainder expected
to be spent in 2002.

In November 2000, the Board of Directors of the Company authorized the
repurchase of up to $30,000,000 of the Company's Common Stock (the "November
2000 Plan"). The November 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 are at the discretion of management based on its view of economic
and financial market conditions. There were no stock repurchases during the six
months ended June 30, 2002. Subsequent to June 30, 2002, the Company has spent
approximately $580,000 for the repurchase of shares of its Common Stock.

The Company believes that cash generated from operations and the total of its
cash and cash equivalents, together with other sources of liquidity, will be
sufficient to fund planned operations and capital equipment purchases for the
foreseeable future. At June 30, 2002, the Company had approximately $740,000 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 significant during the last three fiscal years.

ITEM 3 - QUANTITATIVE AND QUALITATIVE DISCLOSURES 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
short-term investments, changes in the equity price of the Company's investment
in Scipher, plc, a U.K. company, and fluctuations in foreign currency exchange
rates.

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 for these investments is not significant. The
Company's short-term investments consist mainly of corporate and government debt
securities, a major portion of which have maturities of less than one year.
These debt securities are all highly rated investments, in which a significant
portion have interest rates reset at auction at regular intervals. As a result,
the Company believes there is minimal market risk to these investments. The
Company's exposure to market risk for fluctuations in foreign currency exchange
rates relates primarily to the operations of VJCL, and changes in the dollar/yen
exchange rate. The Company believes that this market risk is currently not
material due to the relatively small size of VJCL's operations.

The equity price risk for the Company's investment in Scipher, plc may be
material as the market price of the stock has experienced significant
fluctuations over the past several months. At June 30, 2002, the Company
recorded a loss of $1,078,000 in the investment in Scipher, plc, for a decline
in the value of the investment judged to be other than temporary. At June 30,
2002 the fair value of the investment was approximately $1,447,000.

ITEM 1 - LEGAL PROCEEDINGS



As previously disclosed in Vicor's Form 10-K for the fiscal year ended December
31, 2001 and Form 10-Q for the fiscal quarter ended March 31, 2002, Vicor and
VLT, Inc. ("VLT"), a wholly owned subsidiary of the Company, are pursuing Reset
Patent infringement claims directly against Artesyn Technologies, Lambda
Electronics, Lucent Technologies, Tyco Electronics Power Systems, Inc. and
Power-One in the United States District Court in Boston, Massachusetts. There
can be no assurance that Vicor and VLT will ultimately prevail with respect to
any of these claims or, if they prevail, as to the amount of damages that would
be awarded.

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

In addition, the Company is involved in certain other 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 against the Company to have a material adverse impact on the Company.
