equivalents and short-term investments, as well as cash generated from operations. Consistent
with the Company&#146;s investment policy guidelines, the Company can and has historically invested
its substantial cash balances in demand deposit accounts, money market funds and auction rate
securities meeting certain quality criteria. All of the Company&#146;s investments are subject to
credit, liquidity, market, and interest rate risk.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt; margin-left: 2%">&nbsp;&nbsp;&nbsp;The Company&#146;s short-term and long-term investments are classified as either trading or
available-for-sale securities. Available-for-sale securities are recorded at fair value, with
unrealized gains and losses, net of tax, attributable to credit loss recorded through the
statement of operations and unrealized gains and losses, net of tax, attributable to other
non-credit factors recorded in &#147;Accumulated other comprehensive loss&#148;, a component of
Stockholders&#146; Equity. In determining the amount of credit loss, the Company compared the present
value of cash flows expected to be collected to the amortized cost basis of the securities,
considering credit default risk probabilities and changes in credit ratings as significant
inputs, among other factors. Trading securities are recorded at fair value, with unrealized
gains and losses recorded through the Condensed Consolidated Statements of Operations each
reporting period. The amortized cost of debt securities is adjusted for amortization of premiums
and accretion of discounts to maturity. Such amortization, along with interest and realized
gains and losses, are included in &#147;Other income (expense), net&#148; in the Condensed Consolidated
Statements of Operations. The Company periodically evaluates investments to determine if
impairment is required, whether an impairment is other than temporary, and the measurement of an
impairment loss. The Company considers a variety of impairment indicators such as, but not
limited to, a significant deterioration in the earnings performance, credit rating, or asset
quality of the investment.

</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt; margin-left: 2%">&nbsp;&nbsp;&nbsp;As of March&nbsp;31, 2010, the Company held $30,200,000 of auction rate securities at par value,
consisting of collateralized debt obligations, supported by pools of student loans, sponsored by
state student loan agencies and corporate student loan servicing firms. The interest rates for
these securities are reset at auction at regular intervals ranging from seven to 90&nbsp;days. The
auction rate securities held by the Company traded at par prior to February&nbsp;2008 and are callable
at par at the option of the issuer. On March&nbsp;31, 2010, the majority of the auction rate
securities held by the Company were AAA/Aaa rated by the major credit rating agencies, with all
of the securities collateralized by student loans, of which most are guaranteed by the U.S.
Department of Education under the Federal Family Education Loan Program.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt; margin-left: 2%">&nbsp;&nbsp;&nbsp;Until February&nbsp;2008, the auction rate securities market was liquid, as the investment banks
conducting the periodic &#147;Dutch auctions&#148; by which interest rates for the securities had been
established had committed their capital to support such auctions in the event of insufficient
third-party investor demand. Starting the week of February&nbsp;11, 2008, a substantial number of
auctions failed, as demand from third-party investors weakened and the investment banks
conducting the auctions chose not to commit capital to support such auctions (i.e., investment
banks chose not to purchase securities themselves in order to balance supply and demand, thereby
facilitating a successful auction, as they had done in the past). The consequences of a failed
auction are (a)&nbsp;an investor must hold the specific security until the next scheduled auction
(unless that investor chooses to sell the security to a third party outside of the auction
process) and (b)&nbsp;the interest rate on the security generally resets to an interest rate set forth
in each security&#146;s indenture.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt; margin-left: 2%">&nbsp;&nbsp;&nbsp;As of March&nbsp;31, 2010, the Company held auction rate securities that had experienced failed
auctions totaling $30,200,000 at par value (the &#147;Failed Auction Securities&#148;), of which $125,000
was redeemed at par subsequent to March&nbsp;31, 2010. Management is not aware of any reason to
believe any of the issues of the Failed Auction Securities held by the Company are presently at
risk of default. Through March&nbsp;31, 2010, the Company has continued to receive interest payments
on the Failed Auction Securities in accordance with the terms of their respective indentures.
Management believes the Company ultimately should be able to liquidate all of its auction rate
security investments without significant loss primarily due to the overall quality of the issues
held and the collateral securing the substantial majority of the underlying obligations.
However, current conditions in the auction rate securities market have led management to
conclude the recovery period for the Failed Auction Securities exceeds 12&nbsp;months. As a result,
the Company continued to classify the Failed Auction Securities as long-term as of March&nbsp;31,
2010, except for the $125,000 redeemed at par subsequent to March&nbsp;31, 2010, which was
reclassified to short-term.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt; margin-left: 2%">&nbsp;&nbsp;&nbsp;In November&nbsp;2008, the Company entered into an agreement with UBS AG (&#147;UBS&#148;) regarding
$18,300,000 of auction rate securities at par value held by the Company with a broker-dealer
affiliate of UBS (the &#147;UBS ARS&#148;), of which $7,550,000 have subsequently been redeemed at par.
The agreement provides the Company a contractual right (the &#147;ARS Right&#148;) that entitles the
Company to sell the auction rate securities it holds with UBS to UBS at par during the period of
June&nbsp;30, 2010, through July&nbsp;2, 2012. Until then, the Company is entitled to receive interest
payments on its auction rate securities in accordance with their terms. The terms and conditions
of the settlement included a release of claims against UBS and its affiliates. The ARS Right is
a separate free-standing instrument accounted for separately from the UBS ARS and is accounted
for as a purchased put option. The Company elected fair value accounting for the ARS Right. The
election was made to mitigate volatility in earnings caused by accounting for the receipt of the
ARS Right and the underlying auction rate securities under different methods. The fair value of
the ARS Right was estimated by the Company to be approximately $929,000 on March&nbsp;31, 2010, a
decrease of approximately $33,000 from the estimated fair value on December&nbsp;31, 2009. This
decrease in fair value is recorded as an unrealized loss in &#147;Other income (expense), net&#148; in the
Condensed Consolidated Statements of Operations. While the Company has the ability to exercise
the ARS Right in June&nbsp;2010, it has not made a formal decision to do so. Therefore, the total
amount of the UBS ARS of
$10,750,000 at par value and the ARS Right of $929,000 on March&nbsp;31, 2010 are classified as
long-term trading securities. Based on the fair value measurements described in Note 3, the fair
value of the UBS ARS on March&nbsp;31, 2010, was estimated to be approximately $9,817,000, an increase
in fair value, net of redemptions of $3,150,000, of approximately $37,000 from December&nbsp;31, 2009.
This increase has been recorded as an unrealized gain in &#147;Other income (expense), net&#148; in the
Condensed Consolidated Statements of Operations.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt; margin-left: 2%">&nbsp;&nbsp;&nbsp;The remaining balance of the Company&#146;s auction rate securities is held with a broker-dealer
affiliate of Bank of America (the &#147;BofA ARS&#148;). Based on the fair value measurements described in
Note 3, the fair value of the BofA ARS on March&nbsp;31, 2010,

$16,434,000, a decrease in fair value of $426,000, net of $250,000 of redemptions from December
31, 2009. The gross unrealized loss of $3,016,000 on the BofA ARS consists of two types of
estimate loss: an aggregate credit loss of $507,000 and an aggregate temporary impairment of
$2,509,000. For the period, the aggregate credit loss on the BofA ARS increased by a net amount
of $43,000, which was recorded in &#147;Net impairment losses recognized in earnings&#148; in the Condensed
Consolidated Statement of Operations. In determining the amount of credit loss, the Company
compared the present value of cash flows expected to be collected to the amortized cost basis of
the securities, considering credit default risk probabilities and changes in credit ratings as
significant inputs, among other factors (See Note 3).

other comprehensive (loss)&nbsp;income&#148; in the Condensed Consolidated Balance Sheet by $383,000 to
reflect a decrease in the estimated value of the BofA ARS.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt; margin-left: 2%">&nbsp;&nbsp;&nbsp;At this time, the Company has no intent to sell any of the impaired BofA ARS and does not
believe that it is more likely than not that the Company will be required to sell any of these
securities. Management expects the securities to regain liquidity as the financial markets
recover from the current economic downturn. If current market conditions deteriorate further,
the Company may be required to record additional unrealized losses. If the credit rating of the
security deteriorates, or the anticipated recovery in the market values does not occur, the
Company may be required to adjust the carrying value of these investments through impairment
charges recorded in the Condensed Consolidated Statement of Operations, and any such impairment
adjustments may be material.

expected operating cash flows, management does not anticipate the current lack of liquidity
associated with the auction rate securities held will affect the Company&#146;s ability to execute its
current operating plan.

would be received to sell an asset or paid to transfer a liability (i.e., an exit price) in the
principal or most advantageous market for the asset or liability in an orderly transaction
between market participants on the measurement date. As such, fair value is a market-based

<DIV align="left" style="font-size: 10pt; margin-top: 6pt; margin-left: 2%">&nbsp;&nbsp;&nbsp;As of March&nbsp;31, 2010, there was insufficient observable auction rate security market
information available to determine the fair value of the Failed Auction Securities and the ARS
Right using Level 1 or Level 2 inputs. As such, the Company&#146;s investments in Failed Auction
Securities were deemed to require valuation using Level 3 inputs. Management, after consulting
with advisors, valued the Failed Auction Securities using analyses and pricing models similar to
those used by market participants (i.e., buyers, sellers, and the broker-dealers responsible for
execution of the Dutch auction pricing mechanism by which each issue&#146;s interest rate was set).
Management utilized a probability weighted discounted cash flow (&#147;DCF&#148;) model to determine the
estimated fair value of these securities as of March&nbsp;31, 2010. The major assumptions used in
preparing the DCF model included estimates for the amount and timing of future interest and
principal payments based on default probability assumptions used to measure the credit loss of
approximately 3% for AAA rated securities, the rate of return required by investors to own these
securities in the current environment, which we estimate to be 5% above the risk free rate of
return, and the estimated timeframe for successful auctions for these securities to occur being
three to five years. In making these assumptions, management considered relevant factors
including: the formula applicable to each security defining the interest rate paid to investors
in the event of a failed auction; forward projections of the interest rate benchmarks specified
in such formulas; the likely timing of principal repayments; the probability of full repayment
considering the guarantees by the U.S. Department of Education of the underlying student loans,
guarantees by other third parties, and additional credit enhancements provided through other
means; and publicly available pricing data for recently issued student loan asset-backed
securities not subject to auctions. The estimate of the rate of return required by investors to
own these securities also considered the currently reduced liquidity for auction rate securities.
An increase or decrease
in the liquidity risk premium (i.e., the discount rate) of 100 basis points as used in the
model would decrease or increase, respectively, the fair value of the Failed Auction Securities
by approximately $1,200,000.

expected market conditions. If the Company&#146;s estimated demand and / or market expectation were
to change or if product sales were to decline, the Company&#146;s estimation process may cause larger
inventory reserves to be recorded, resulting in larger charges to cost of revenues.

Semiconductor Corporation (&#147;GWS&#148;) totaled $5,000,000 as of March&nbsp;31, 2010, and December&nbsp;31, 2009,
giving the Company an approximately 30% ownership interest in GWS. GWS and its subsidiary design
and sell semiconductors, conduct research and development activities, develop and license
patents, and litigate against those who infringe upon patented technology. A director of the
Company is the founder, Chairman of the Board, President and Chief Executive Officer (&#147;CEO&#148;), as
well as the majority voting shareholder, of GWS. The Company and GWS are parties to an
intellectual property cross-licensing agreement, a license agreement and two supply agreements,
and the Company purchases certain components from GWS. Purchases from GWS totaled approximately
$671,000 and $341,000 for the three months ended March&nbsp;31, 2010, and 2009, respectively.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt; margin-left: 2%">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Company accounts for its investment in GWS under the equity method of accounting. The
Company has determined that, while GWS is a variable interest entity, the Company is not the
primary beneficiary. The key factors in the Company&#146;s assessment were that the CEO of GWS has:
(i)&nbsp;the power to direct the activities of GWS that most significantly impact its economic
performance, and (ii)&nbsp;has an obligation to absorb losses or the right to receive benefits from
GWS, respectively, that could potentially be significant to GWS.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt; margin-left: 2%">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;There was no allocation of equity method income (loss)&nbsp;for the three months ended March&nbsp;31,
2010 and 2009, as GWS incurred a net loss in each period. Due to an adjustment to the investment
for a decline in value judged to be other than temporary during the fourth quarter of 2008, the
amounts included in &#147;Other assets&#148; in the accompanying Condensed Consolidated Balance Sheets
related to the net GWS investment were zero as of March&nbsp;31, 2010, and December&nbsp;31, 2009.

which includes estimated federal, state and foreign income taxes on the Company&#146;s projected
annual pre-tax income and estimated federal and state income taxes for certain minority-owned
subsidiaries that are not part of the Company&#146;s consolidated income tax returns, offset by the
expected utilization of federal and foreign net operating loss carryforwards. The tax provision
in 2009 provided for estimated income taxes due in various state and international taxing
jurisdictions for which losses incurred by the Company cannot be offset, and for estimated
federal and state income taxes for certain minority-owned subsidiaries that are not part of the
Company&#146;s consolidated income tax returns. The 2010 and 2009 tax provisions also include
discrete items, principally expense for increases in state taxes and accrued interest for
potential liabilities.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt; margin-left: 2%">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Company recorded income tax expense for the three months ended March&nbsp;31, 2009, based on
a discrete-period computation because it believed a reliable estimate of its effective annual tax
rate could not be made at that time. This was due to the difficulty in accurately forecasting
the expected ordinary income (loss)&nbsp;for the year and that small variations in any forecast would
have caused wide variability in the estimated tax rate. That variability in the estimated
effective annual tax rate is more limited when projecting annual pre-tax income for 2010 and,
thus, the Company utilized the effective tax rate method in calculating the tax provision for the
three months ended March&nbsp;31, 2010.

compared to 2009 was principally due to the impact of using the effective tax rate method versus a
discrete-period computation and increases in expense for state taxes, partially offset by lower tax
expense in 2010 for one of the minority-owned subsidiaries that is not part of the Company&#146;s
consolidated income tax returns.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt; margin-left: 2%">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On February&nbsp;22, 2007, the Company announced it had reached an agreement in principle with
Ericsson, Inc., the U.S. affiliate of LM Ericsson, to settle a lawsuit brought by Ericsson
against the Company in California state court. Under the terms of the settlement agreement
entered into on March&nbsp;29, 2007, after a court ordered mediation, the Company paid $50,000,000 to
Ericsson, of which $12,800,000 was reimbursed by the Company&#146;s insurance carriers. Accordingly,
the Company recorded a net loss of $37,200,000 from the litigation-related settlements in the
fourth quarter of 2006. The Company has been seeking further reimbursement from its insurance
carriers. On November&nbsp;14, 2008, a jury in the United States District Court for the District of
Massachusetts found in favor of the Company in a lawsuit against certain of its insurance
carriers with respect to the Ericsson settlement. The jury awarded $17,300,000 in damages to
Vicor, although the verdict is subject to challenge in the trial court and on appeal. Both
parties filed certain motions subsequent to the ruling and, on March&nbsp;2, 2009, the judge in the
case rendered his decision on the subsequent motions, reducing the jury award by $4,000,000. On
March&nbsp;26, 2009, the U.S. District Court, District of Massachusetts issued its judgment in the
matter, affirming the award of $13,300,000, plus prejudgment interest from the date of breach on
March&nbsp;29, 2007, through March&nbsp;26, 2009, the date of judgment in the amount of approximately
$3,179,000. The insurance carriers have filed their appeal to this total judgment in the amount
of approximately $16,479,000.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt; margin-left: 2%">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In addition, the Company is involved in certain other litigation and claims incidental to
the conduct of its business. While the outcome of lawsuits and claims against the Company cannot
be predicted with certainty, management does not expect any current litigation or claims to have
a material adverse impact on the Company&#146;s financial position or results of operations.

Consolidation of Variable Interest Entities. The new accounting standard replaces the
quantitative-based risks and rewards calculation for determining which enterprise, if any, has a
controlling financial interest in a variable interest entity with an approach focused on
identifying which enterprise has the power to direct the activities of a variable interest entity
that most significantly impact the entity&#146;s economic performance and (1)&nbsp;the obligation to absorb
losses of the entity or (2)&nbsp;the right to receive benefits from the entity. The new standard also
provides additional reconsideration events for determining whether an entity is a variable
interest entity and requirements for ongoing assessments of whether an enterprise is the primary
beneficiary of a variable interest entity. The adoption of this new accounting guidance did not
have a material effect on the Company&#146;s financial position or results of operations.

between Levels 1, 2, and 3. The adoption of this new accounting guidance did not have a material

forward-looking statements. Forward-looking statements also include statements regarding the
derivation of a portion of the Company&#146;s sales in each quarter from orders booked in the same
quarter, the Company&#146;s plans to invest in research and development and manufacturing equipment, the
Company&#146;s belief regarding market risk being mitigated because of limited foreign exchange
fluctuation exposure, the Company&#146;s continued success depending in part on its ability to attract
and retain qualified personnel, the Company&#146;s belief that cash generated from operations and the
total of its cash and cash equivalents and short-term investments will be sufficient for the
foreseeable future, the Company&#146;s intention regarding protecting its rights under its patents and
the Company&#146;s expectation that no current litigation or claims will have a material adverse impact
on its financial position or results of operations. These statements are based upon the Company&#146;s
current expectations and estimates as to the prospective events and circumstances which may or may
not be within the Company&#146;s control and as to which there can be no assurance. Actual results
could differ materially from those projected in the forward-looking statements as a result of
various factors, including our ability to develop and market new products and technologies cost
effectively, to leverage design wins into increased product sales, to continue to make progress
with key customers and prospects, to decrease manufacturing costs, to enter into licensing
agreements that amplify the market opportunity and accelerate market penetration, to realize
significant royalties under license agreements, to achieve a sustainable increased bookings rate
over a longer period, to hire key personnel and to continue to build our three business units, to
successfully enforce our intellectual property rights, to successfully defend outstanding
litigation, to successfully leverage the V<B>*</B>I Chips in standard products to promote market
acceptance of Factorized Power Architecture, to develop or maintain an effective system of internal
controls, to obtain required financial information for certain investments on a timely basis, and
factors impacting the Company&#146;s various end markets, the impact of write-downs in the value of
assets, the effects of equity accounting with respect to certain affiliates, the failure of auction
rate securities to sell at their reset dates as well as those factors described in the risk
factors set forth in the Company&#146;s Annual Report on Form 10-K for the year ended December&nbsp;31, 2009,
under Part&nbsp;I, Item&nbsp;I &#151; &#147;Business,&#148; under Part&nbsp;I, Item&nbsp;1A &#151; &#147;Risk Factors,&#148; under Part&nbsp;I, Item&nbsp;3

Financial Condition and Results of Operations.&#148; The risk factors contained in this report may not
be exhaustive. Therefore, the information contained in this report should be read together with
other reports and documents that the Company files with the Securities and Exchange Commission from

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;Revenues for the first quarter increased by 2.5% to $51,709,000, compared to $50,448,000 for
the corresponding period a year ago, and increased 5.2% on a sequential basis from $49,138,000 for
the fourth quarter of 2009. Gross margin increased to $23,324,000 for the first quarter of 2010,
compared to $21,831,000 for the corresponding period a year ago, and increased on a sequential
basis from $22,497,000 for the fourth quarter of 2009. Gross margin, as a percentage of revenue,
increased to 45.1% for the first quarter of 2010 compared to 43.3% for the first quarter of 2009,
but decreased on a sequential basis from 45.8% for the fourth quarter of 2009. Net income (loss)
attributable to Vicor Corporation for the first quarter was $1,952,000, or $0.05 per diluted share,
compared to net income (loss)&nbsp;attributable to Vicor Corporation of $(2,543,000), or $(0.06) per
diluted share, for the corresponding period a year ago and net income (loss)&nbsp;attributable to Vicor
Corporation of $2,309,000, or $0.06 per diluted share, for the fourth quarter of 2009.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;The book-to-bill ratio, calculated by the dollar amount of orders placed with scheduled
delivery dates within one year divided by the net revenues in the respective period, was 1.39:1 for
the first quarter of 2010, compared to 1.16:1 for the fourth quarter of 2009. Backlog,
representing the total of purchase orders received for which product has not yet been shipped, was
$78,400,000 at the end of the first quarter of 2010, as compared to $58,500,000 at the end of the
fourth quarter of 2010.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;Operating expenses for the three months ended March&nbsp;31, 2010, decreased $2,924,000, or 12.4%,
to $20,748,000 from $23,672,000 for the same period in 2009, principally due to a pre-tax charge of
$3,098,000 recorded in the first quarter of 2009 for severance and other employee-related costs in
connection with a workforce reduction implemented during the quarter and a decrease in selling,
general and administrative expenses of $943,000, partially offset by an increase in research and
development expenses of $1,117,000. The key decreases in selling, general and administrative
expenses were compensation expenses of $627,000, commission expense of $342,000 and legal fees of
$134,000. The key increases in research and development expenses were compensation expenses of
$465,000, outside services of $242,000 and project materials of $176,000.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;Other income (expense), net for the three months ended March&nbsp;31, 2010 decreased $51,000 to
$67,000 from $118,000 in 2009. The primary reason for the decrease was a decrease in interest
income of $75,000.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;For the three months ended March&nbsp;31, 2010, depreciation and amortization was $2,432,000, and
capital additions were $2,429,000, compared to $2,625,000 and $1,029,000, respectively, for the
first three months of 2009.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;Inventories increased by approximately $353,000 or 1.7% to $21,710,000, as compared with
$21,357,000 at December&nbsp;31, 2009. The increase was primarily attributed to increases in BBU and
Picor inventories of approximately $271,000 and $200,000, respectively, partially offset by a
decrease in V*I Chip&#146;s inventories of $118,000.

fourth quarter of 2009. This increase was caused by an increase in BBU orders of 9.8% and an
increase in V*I Chip orders during the period of 223.8%. The consolidated book to bill ratio for
the three months ending March&nbsp;31, 2010, was 1.39:1, as compared to 0.99:1 for the corresponding
period a year ago, and 1.16:1 for the fourth quarter of 2009. The quarterly book-to-bill ratio has
been volatile and management believes that the ratio is not always an accurate indicator of the
amount or timing of future revenue.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;Gross margin for the first quarter of 2010 increased $1,493,000, or 6.8%, to $23,324,000 from
$21,831,000 in the first quarter of 2009. Gross margin, as a percentage of net revenues, increased
to 45.1% from 43.3% as a percentage of net revenues. The primary components of the increase in
gross margin dollars and percentage were the increase in net revenues and lower brick production
costs.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;Selling, general and administrative expenses were $11,880,000 for the period, a decrease of

administrative expenses as a percentage of net revenues, decreased to 23.0% from 25.4% for the same

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;The decrease in interest income is due to lower average balances on the Company&#146;s short and
long-term investments as well as a decrease in interest rates. The Company&#146;s exposure to market
risk for fluctuations in foreign currency exchange rates relates primarily to the operations of
VJCL. The functional currency of the Company&#146;s subsidiaries in Europe and Hong Kong is the U.S.
dollar. The unrealized gains (losses)&nbsp;and credit loss on the Company&#146;s auction rate securities and
securities rights results from the change in fair value of these investments during the period.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;The increase in the provision for income taxes in the three months ended March&nbsp;31, 2010,
compared to 2009 was principally due to the impact of using an effective tax rate method in 2010
versus a discrete-period computation in 2009 and increases in expense for state taxes, partially
offset by lower tax expense in 2010 for one of the minority-owned subsidiaries that is not part of
the Company&#146;s consolidated income tax returns.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;Net income of noncontrolling interest decreased $339,000 to $53,000 in first quarter of 2010
from $392,000 for the same period in 2009. This was due to lower net income at certain entities in
which the Company holds a noncontrolling interest.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;Basic and diluted income (loss)&nbsp;per share attributable to Vicor Corporation was $0.05 for the
first quarter of 2010 compared to $(0.06) for the first quarter of 2009.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt"><U>Liquidity and Capital Resources</U>
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;At March&nbsp;31, 2010, the Company had $41,661,000 in unrestricted cash and cash equivalents. The
ratio of current assets to current liabilities was 4.6:1 at March&nbsp;31, 2010, and December&nbsp;31, 2009.
Working capital increased $3,621,000 to $78,412,000 at March&nbsp;31, 2010, from $74,791,000 at December
31, 2009. The primary factors affecting the working capital increase were increases in accounts
receivable of $4,570,000, cash and cash equivalents of $1,437,000, inventories of $353,000, other
current assets of $239,000, as well as a decrease in accounts payable of $535,000, offset by
decreases in short term investments of $2,011,000, as well as increases in accrued compensation and
benefits of $817,000, deferred revenue of $608,000, and income taxes payable of $302,000. The
primary source of cash for the three months ended March&nbsp;31, 2010, was $3,386,000 in net sales of
short-term and long-term investments and $461,000 from operating activities. The primary use of
cash for the three months ended March&nbsp;31, 2010 was $2,429,000 for the purchase of equipment.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;As of March&nbsp;31, 2010, the Company held $30,075,000 of auction rate securities classified as
long-term investments and $125,000 classified as short-term investments. Please see Note 2 of the
Company&#146;s Condensed Consolidated Financial Statements for a discussion of the securities and the
Company&#146;s accounting treatment thereof.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;In November&nbsp;2000, the Board of Directors of the Company authorized the repurchase of up to
$30,000,000 of the Company&#146;s Common Stock (the &#147;November&nbsp;2000 Plan&#148;). The November&nbsp;2000 Plan
authorizes the Company to make such repurchases from time to time in the open market or through
privately negotiated transactions. The timing and amounts of stock repurchases are at the
discretion of management based on its view of economic and financial market conditions. The Company
did not repurchase shares of Common Stock during the three months ended March&nbsp;31, 2010. As of
March&nbsp;31, 2010, the Company had approximately $8,541,000 remaining under the November&nbsp;2000 Plan.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;The Company&#146;s primary liquidity needs are for making continuing investments in manufacturing
equipment, particularly equipment to increase capacity for our V*I Chip products. The Company
believes cash generated from operations and the total of its cash and cash equivalents and
short-term investments will be sufficient to fund planned operations and capital equipment
purchases for the foreseeable future. The Company had approximately $1,478,000 of capital
expenditure commitments, principally for manufacturing equipment, as of March&nbsp;31, 2010.

</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Company is exposed to a variety of market risks, including changes in interest rates
affecting the return on our cash and cash equivalents and short-term investments and fluctuations
in foreign currency exchange rates. As the Company&#146;s cash and cash equivalents consist principally
of money market securities, which are short-term in nature, the Company believes our exposure to
market risk on interest rate fluctuations for these investments is not significant. The Company&#146;s
short-term and long-term investments consist mainly of municipal and corporate debt securities, of
which the Failed Auction Securities represent a significant portion. While the Failed Auction
Securities are all highly rated investments, generally with AAA/Aaa ratings, continued failure to
sell at their reset dates could negatively impact the carrying value of the investments, in turn
leading to impairment charges in future periods. Currently, changes in the fair value of the Failed
Auction Securities held with UBS are recorded through earnings. Changes in the fair value of the
Failed Auction Securities held with BofA attributable to credit loss are recorded through earnings,
with the remainder of any change recorded in &#147;Accumulated other comprehensive (loss)&nbsp;income.&#148;
Should a decline in the value of the Failed Auction Securities held with BofA be other than
temporary, the losses would be recorded in &#147;Other income (expense), net.&#148; The Company does not
believe there was an &#147;other-than-temporary&#148; decline in value in these securities as of March&nbsp;31,
2010.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Company&#146;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, as the
functional currency of the Company&#146;s subsidiaries in Europe and Hong Kong is the U.S. dollar.
Therefore, the Company believes market risk is mitigated since these operations are not materially
exposed to foreign exchange fluctuations.

</TABLE>
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;As required by Rule&nbsp;13a-15 under the Securities Exchange Act, the Company&#146;s management, with
the participation of the Company&#146;s Chief Executive Officer (&#147;CEO&#148;) and Chief Financial Officer
(&#147;CFO&#148;), conducted an evaluation of the effectiveness of the Company&#146;s disclosure controls and
procedures, as of the end of the last fiscal quarter (i.e., March&nbsp;31, 2010). In designing and
evaluating the Company&#146;s disclosure controls and procedures, the Company and its management
recognize that any controls and procedures, no matter how well designed and operated, can provide
only reasonable assurance of achieving the desired control objectives, and management necessarily
was required to apply its judgment in evaluating and implementing possible controls and procedures.
Based upon that evaluation, management, including the Company&#146;s CEO and CFO, has concluded the
Company&#146;s disclosure controls and procedures as of March&nbsp;31, 2010, were reasonably effective to
ensure that information required to be disclosed by the Company in the reports it files or submits
under the Exchange Act is recorded, processed, summarized and reported within the time periods
specified in the Securities and Exchange Commission&#146;s rules and forms. Management intends to
continue to review and document the Company&#146;s disclosure controls and procedures, including
internal controls over financial reporting, and may from time to time make changes to the
disclosure controls and procedures to enhance their effectiveness and to ensure that the Company&#146;s
systems evolve with its business.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;A control system, no matter how well designed and operated, can provide only reasonable, not
absolute, assurance that the control system&#146;s objectives will be met. Accordingly, management,
including the CEO and CFO, recognizes the Company&#146;s disclosure controls or its internal control
over financial reporting may not prevent or detect all errors and all fraud. The design of a
control system must reflect the fact that there are resource constraints, and the benefits of
controls must be considered relative to their costs. Further, because of the inherent limitations
in all control systems, no evaluation of controls can provide absolute assurance that misstatements
due to error or fraud will not occur or that all control issues and instances of fraud, if any,
within the Company have been detected. These inherent limitations include the realities that
judgments in decision-making can be faulty and that breakdowns can occur because of simple error or
mistake. Controls can also be circumvented by the individual acts of some persons, by collusion of
two or more people, or by management override of the controls. The design of any system of
controls is based in part on certain assumptions about the likelihood of future events, and there
can be no assurance that any design will succeed in achieving its stated goals under all potential
future conditions. Projections of any control&#146;s effectiveness to future periods are subject to
risks. Over time, controls may become inadequate because of changes in conditions or deterioration in the degree
of compliance with policies or procedures.
