                     NOTES TO CONDENSED FINANCIAL STATEMENTS

                                   (unaudited)

1.  Basis of Presentation

       The accompanying unaudited condensed financial statements have been
prepared by RITA Medical Systems, Inc. (the "Company") in accordance with
accounting principles generally accepted in the United States of America for
interim financial information. These principles are consistent in all material
respects with those applied in the Company's financial statements contained in
our annual report on Form 10-K for the fiscal year ended December 31, 2000 and
pursuant to the instructions to Form 10-Q and Article 10 of Regulation S-X
promulgated by the Securities and Exchange Commission. However, interim
financial statements do not include all of the information and footnotes
required by generally accepted accounting principles for complete financial
statements. In the opinion of management, the accompanying unaudited condensed
financial statements contain all adjustments (all of which are normal and
recurring in nature) necessary to present fairly the financial position, results
of operations and cash flows of the Company for the periods indicated. Interim
results of operations are not necessarily indicative of the results to be
expected for the full year or any other interim periods. These condensed
financial statements should be read in conjunction with the financial statements
and footnotes thereto for the year ended December 31, 2000 contained in the
Company's annual report on Form 10-K.

2.  Net loss per share

       Basic earnings (loss) per share figures are calculated based on the
weighted-average number of common shares outstanding during the period. Diluted
earnings (loss) per share figures include the dilutive effect of common stock
equivalents consisting of stock options, warrants, shares subject to repurchase
and shares issuable upon conversion of preferred stock provided that the
inclusion of such common stock equivalents is not antidilutive. For the three
months ended June 30, 2001 and June 30, 2000, and for the six months ended June
30, 2001 and June 30, 2000, the Company has excluded potentially dilutive
securities from earnings per share computations as they have an antidilutive
effect due to the Company's net losses. The following weighted options and
warrants (prior to application of the treasury stock method), convertible
preferred shares (on an as-if-converted method) and common shares subject to
repurchase were so excluded (in thousands):

4. Contingency

     The Company is involved in a patent interference proceeding with
RadioTherapeutics Corporation in which the validity of a patent issued to the
Company has been called into question. Although the Company believes it has
meritorious defenses, if it does not prevail in this interference, it could be
prevented from selling the RITA system or be required to pay license fees and or
royalties on past and future product sales.

Overview

     We develop, manufacture and market minimally invasive products that use
radiofrequency energy to treat patients with solid cancerous or benign tumors.
From inception in 1994 through 1996, our operations consisted primarily of
various start-up activities, including development of technologies central to
our business, recruiting personnel and raising capital. In 1997, we began
commercial product shipments. In 2000, we commercially launched our Model 1500
generator and StarBurst family of disposable devices and significantly expanded
our direct domestic sales organization and our international distribution
network.

     Our products are sold in the United States through our direct sales force
and internationally through distribution partners. For the three months ended
June 30, 2001, sales in the United States accounted for 46% of our total sales
while sales in our international markets accounted for 54% of our total sales.
The percentage of our revenues from international markets has decreased in 2001
as reimbursement concerns in Europe and Japan have slowed the growth of our
business in these markets. We expect this trend to continue through the balance
of 2001 and 2002. Longer term, we expect that a significant portion of our
revenue will continue to come from international operations because of the high
incidence of primary liver cancer in Asian and European markets.

     All of our revenue is derived from the sale of our disposable devices and
radiofrequency generators. For the three months ended June 30, 2001, 78% of our
sales were derived from our disposable devices and 22% were derived from the
sale of our generators. Placement of generators at hospitals is necessary for
customers to use our disposable devices, and we continue to focus on expanding
our base of customer accounts. We are also continuing to focus on increasing
usage of our disposable products at our established accounts, and we expect that
a significant proportion of our revenues will continue to be derived from the
sale of our higher-margin disposable devices.

     Our manufacturing costs consist of raw materials, including generators
produced for us by third-party suppliers, labor to produce our disposable
devices and to inspect incoming, in-process and finished goods, sterilization
performed by an outside service provider and general overhead expenses. Gross
margins are affected by production volumes and average selling prices. In
addition, margins are affected by the sales mix of disposable devices versus
generators, the mix of domestic direct sales versus international sales, which
provide for standard distributor discounts, and our regular provisions for
obsolete or obsolescent inventory.

     For the three months ended June 30, 2001, 32% of our operating expenses
were related to research and development activities, while 68% of our operating
expenses were related to selling, general and administrative activities. We
expect to continue to devote significant resources to product development and
clinical research programs. We also expect to continue to devote the majority of
our operating expenses to selling, general and administrative activities,
particularly to our sales and marketing efforts. These efforts include the
selective expansion of our domestic sales force and our international
distribution support activities as well as physician training and patient
awareness programs.

     In connection with grants of stock options to employees and non-employees,
we record deferred stock-based compensation as a component of stockholders'
equity. This stock-based compensation is amortized as charges to operations over
the vesting periods of the options. We recorded amortization of deferred
compensation of $0.5 million for the three months ended June 30, 2001. We expect
to record additional amortization expense for deferred compensation in future
periods.

     We incurred net losses of $3.0 million for the three months ended June 30,
2001. As of June 30, 2001, we had an accumulated deficit of $47.6 million. Due
to the high costs associated with continued research and development programs,
expanded clinical research programs and increased sales and marketing efforts,
we expect to continue to incur net losses for the balance of 2001 and for the
year 2002.

                                       -8-



     Our future growth depends on expanding product usage in our current market
and finding new large markets in which we can leverage our core technologies of
applying radiofrequency energy to treat cancerous and benign tumors. To the
extent our current or new markets do not materialize in accordance with our
expectations, our sales could be lower than expected.

     We are currently involved in patent proceedings and may become a party to
additional patent or product liability proceedings. The costs of such lawsuits
or proceedings may be material and could affect our earnings and financial
position. An adverse outcome in a patent lawsuit could require us to cease sales
of affected products or to pay royalties and/or license fees, which could harm
our results of operations.

Results of Operations

Three months ended June 30, 2001 and 2000

     Sales increased 55% to $3.8 million for the quarter ended June 30, 2001
from $2.4 million for the quarter ended June 30, 2000. We saw growth in both
domestic and international markets, with domestic sales increasing by 78% and
international sales up by 40% over the comparable prior year period. Sales of
our disposable products totaled $2.9 million for the quarter, an increase of
100% over the comparable prior year period. Higher unit shipments of disposable
products resulted from increased physician awareness of our technology,
expansion of our domestic sales force and increased geographical representation
through the appointment of new international distributors. Also, average selling
prices of disposable products benefited from the increasing proportion of
domestic business in our sales mix. Generator sales for the quarter were 14%
lower than sales in the second quarter of 2000, but generator volume in the
second quarter of 2000 was unusually high due to the introduction of our Model
1500 generator.

     Cost of goods sold for the quarter ended June 30, 2001 was $1.7 million
compared to $1.5 million for the quarter ended June 30, 2000. The growth in cost
of goods sold was attributable primarily to higher material, labor, and overhead
costs associated with increased unit shipments. Charges to cost of goods sold
for amortization of deferred stock-based compensation were $0.1 million for the
period compared to $0.3 million for the corresponding period in 2000.

     Research and development expenses for the quarter ended June 30, 2001 were
$1.7 million compared to $1.4 million for the corresponding period in 2000. This
increase was attributable to new product development charges and increased
activity in clinical programs investigating new applications for our technology.
Charges to research and development expense for amortization of deferred
stock-based compensation were $0.1 million for the period compared to $0.3
million for the corresponding period in 2000.

     Selling, general and administrative expenses for the quarter ended
June 30, 2001 were $3.8 million as compared to $2.7 million in the corresponding
period in 2000. The increase resulted from the major expansion of our domestic
sales organization, increased administrative expenses due to added personnel to
support our growth in operations and additional costs associated with our
operation as a public company. Charges to selling, general and administrative
expense for amortization of deferred stock-based compensation were $0.3 million
for the period compared to $0.8 million for the corresponding period in 2000.

     Interest income, net of interest expense, was $0.4 million for the quarter
ended June 30, 2001 compared to $15,000 of net expense in the corresponding
period of 2000. The change was primarily attributable to earnings on short-term
investments made with cash received from our initial public offering of common
shares, completed in the third quarter of 2000.

Six months ended June 30, 2001 and 2000

     Sales increased 66% to $7.1 million for the six months ended June 30, 2001
from $4.3 million for the six months ended June 30, 2000. We saw growth in both
domestic and international markets, with domestic sales increasing by 125% and
international sales up by 34% over the comparable prior year period. Sales of
our disposable products totaled $5.4 million for the first six months of 2001,
an increase of 104% over the comparable prior year period, while generator sales
increased 5%. Higher unit shipments of disposable products resulted from
increased physician awareness of our technology, expansion of our domestic sales
force and increased geographical representation through the appointment of new
international distributors. Also, average selling prices of disposable products
benefited from the increasing proportion of domestic business in our sales mix.
Generator volume for the first six months of 2001 was essentially flat with that
of the comparable prior year period.

     Cost of goods sold for the six months ended June 30, 2001 was $3.4 million
compared to $2.7 million for the six months ended June 30, 2000. The growth in
cost of goods sold was attributable primarily to higher material, labor, and
overhead costs associated with increased unit shipments. Charges to cost of
goods sold for amortization of deferred stock-based compensation were $0.4
million for the period compared to $0.7 million for the corresponding period in
2000.


                                       -9-




     Research and development expenses for the six months ended June 30, 2001
were $3.2 million compared to $3.1 million for the corresponding period in 2000.
This increase was attributable to new product development charges and increased
activity in clinical programs investigating new applications for our technology.
Charges to research and development expense for amortization of deferred
stock-based compensation were $0.2 million for the period compared to $0.6
million for the corresponding period in 2000.

     Selling, general and administrative expenses for the six months ended
June 30, 2001 were $7.5 million compared to $5.3 million in the corresponding
period in 2000. The increase resulted from the major expansion of our domestic
sales organization, increased administrative expenses due to added personnel to
support our growth in operations and additional costs associated with our
operation as a public company. Charges to selling, general and administrative
expense for amortization of deferred stock-based compensation were $0.4 million
for the period compared to $2.0 million for the corresponding period in 2000.

     Interest income, net of interest expense, was $1.0 million for the six
months ended June 30, 2001 compared to $20,000 in the corresponding period of
2000. The change was primarily attributable to earnings on short-term
investments made with cash received from our initial public offering of common
shares, completed in the third quarter of 2000.

Liquidity and Capital Resources

     Prior to August 2000, we financed our operations principally through
private placements of convertible preferred stock, raising approximately $37.9
million net of expenses. On August 1, 2000, we completed our initial public
offering of 3.6 million common shares at a price of $12 per share, raising
approximately $39.0 million net of expenses. All outstanding convertible
preferred shares were converted to common shares at that time. To a lesser
extent, we also financed our operations through equipment financing and other
loans, of which there was $0.3 million in principal outstanding at June 30,
2001. As of June 30, 2001, we had $17.2 million of cash and cash equivalents,
$16.1 million of marketable securities and $36.7 million of working capital.

     For the six months ended June 30, 2001, net cash used in operating
activities was $5.7 million, principally due to our net loss and increases in
accounts receivable resulting from higher revenues and increased unit shipments.
Our investing activities for this period were limited to the purchase of
property and equipment in the amount of $0.6 million and net purchases or sales
of short-term investment instruments. Net cash used by financing activities was
$0.5 million in the first six months of 2001 with $1.0 million in debt reduction
offset by proceeds from the issuance of common shares.

     Our capital requirements depend on numerous factors including our
research and development expenditures, expenses related to selling, marketing
and administration as well as working capital to support business growth.
Although it is difficult for us to predict future liquidity requirements with
certainty, we believe that our current cash and cash equivalents will satisfy
our cash requirements for at least the next 18 months. During or after this
period, if cash generated by operations is insufficient to satisfy our liquidity
requirements, we may need to sell additional equity or debt securities or obtain
an additional credit facility. There can be no assurance that additional
financing will be available to us or, if available, that such financing will be
available on terms favorable to the Company and our stockholders.

Factors That May Affect Future Results

     In addition to the other information in this report, the following factors
should be considered carefully in evaluating the Company's business and
prospects.

Due to our dependence on the RITA system, failure to achieve market acceptance
in a timely manner could harm our business.

     Because all of our revenue comes from the sale of the RITA system, our
financial performance will depend upon physician adoption and patient awareness
of this system. If we are unable to convince physicians to use the RITA system,
we may not be able to generate revenues because we do not have alternative
products.

We are currently involved in a patent interference action and a patent
opposition action involving RadioTherapeutics Corporation, and if we do not
prevail in these actions, we may be unable to sell the RITA system.

     In July 1999, the United States Patent and Trademark Office declared an
interference involving us, which was provoked by RadioTherapeutics Corporation,
a competitor of ours, in which the validity of a patent claim previously issued
to us is being called

                                      -10-




into question. The claim being questioned is one of a number of issued patent
claims that cover the curvature of the array at the tip of our disposable
devices. In February 2001, the USPTO issued a decision on preliminary motions
filed in the patent interference proceeding. The decision found that one of the
claims in our United States Patent No. 5,536,267 (claim no. 32) is invalid. We
expect to receive final confirmation of that decision later this year. In the
event that the decision is confirmed, we plan to file a motion in a United
States District Court requesting review of the decision. Final determination of
the patent interference proceeding may take several years. If the final
determination of the United States District Court results in the issuance of
patent rights related to the claim to RadioTherapeutics and we were unable to
obtain a license to use the relevant patent or successfully modify our
disposable device, we could be unable to sell our system and our business could
suffer.

     In March 2000, RadioTherapeutics Corporation filed an opposition to our
European Patent No. 0777445. This patent also covers the curvature of the array
at the tip of our disposable devices. In this opposition, the validity of our
issued patent is being questioned. A final decision is not expected in this
proceeding for several years. If we do not prevail in the opposition proceeding,
we could lose our only currently issued patent in Europe.

We have a history of losses, anticipate significant increases in our operating
expenses over the next several years and may never achieve profitability.

     We anticipate that our operating expenses will increase substantially in
absolute dollars for the foreseeable future as we expand our sales and
marketing, manufacturing, clinical research and product development efforts. To
become profitable, we must continue to increase our sales. If sales do not
continue to grow, we may not be able to achieve or maintain profitability in the
future. Historically, we have never shown a profit for any year or quarterly
reporting period, and our accumulated deficit stands at $47.6 million as of
June 30, 2001.

Because we face significant competition from companies with greater resources
than we have, we may be unable to compete effectively.

     The market for our products is intensely competitive, subject to rapid
change and significantly affected by new product introductions and other market
activities of industry participants.

     We compete directly with two companies in the domestic and international
markets: RadioTherapeutics Corporation, a privately held company, and Radionics,
Inc., a division of Tyco International, a publicly traded company with
substantial resources. Both RadioTherapeutics and Radionics sell products that
use radiofrequency energy to ablate soft tissue. In 1998, RadioTherapeutics
entered into a distribution arrangement with Boston Scientific Corporation, a
publicly traded company with substantially greater resources than we have.

Alternative therapies could prove to be superior to the RITA system, and
physician adoption could be negatively affected.

     In addition to competing against other companies offering products that use
radiofrequency energy to ablate soft tissue, we also compete against companies
developing, manufacturing and marketing alternative therapies that address both
cancerous and benign tumors. If these alternative therapies prove to offer
treatment options that are superior to our system, physician adoption of our
products could be negatively affected and our revenues could decline.

We currently lack long-term data regarding the safety and efficacy of our
products and may find that long-term data does not support our short-term
clinical results.

     Our products are supported by an average clinical follow-up of between five
and 14 months in published clinical reports. If longer-term studies fail to
confirm the effectiveness of our products, our sales could decline. If
longer-term patient follow-up or clinical studies indicate that our procedures
cause unexpected, serious complications or other unforeseen negative effects, we
could be subject to significant liability. Further, because some of our data has
been produced in studies that were not randomized and/or included small patient
populations, our clinical data may not be reproduced in wider patient
populations.

If we are unable to protect our intellectual property rights, we may lose market
share to a competitor and our business could suffer.

     Our success depends significantly on our ability to protect our proprietary
rights to the technologies used in our products, and yet we may be unable to do
so. A number of companies in our market, as well as universities and research
institutions, have issued patents and have filed patent applications that relate
to the use of radiofrequency energy to ablate soft tissue. Our pending United
States and foreign patent applications may not issue or may issue and be
subsequently successfully challenged by others and invalidated. In addition, our
pending patent applications include claims to material aspects of our products
that are not currently

                                      -11-



protected by issued patents. Both the patent application process and the process
of managing patent disputes can be time consuming and expensive.

     In the event a competitor infringes upon our patent or other intellectual
property rights, enforcing those rights may be difficult and time consuming.
Even if successful, litigation to enforce our intellectual property rights or to
defend our patents against challenge could be extensive and time consuming and
could divert our management's attention. We may not have sufficient resources to
enforce our intellectual property rights or to defend our patents against a
challenge. In addition, confidentiality agreements executed by our employees,
consultants and advisors may not be enforceable or may not provide meaningful
protection for our trade secrets or other proprietary information in the event
of unauthorized use or disclosure. If we are unable to protect our intellectual
property rights we could lose market share to a competitor and our business
could suffer.

If we are sued for patent infringement, we could be prevented from selling our
products and our business could suffer.

     We are aware of the existence of patents held by competitors in our market,
which could result in a patent lawsuit against us. In the event that we are
subject to a patent infringement lawsuit and if the relevant patents were upheld
as valid and enforceable and we were found to infringe, we could be prevented
from selling our products unless we could obtain a license or were able to
redesign the product to avoid infringement. If we were unable to obtain a
license or successfully redesign our system, we may be prevented from selling
our system and our business could suffer.

Our dependence on international revenues, which account for a significant
portion of our revenues, could harm our business.

     Because our future profitability will depend in part on our ability to grow
product sales in international markets, we are exposed to risks specific to
business operations outside the United States. These risks include:

       -  the challenge of managing international sales without direct access to
          the end customer;

       -  the risk of inventory build-up by our distributors which could
          negatively impact sales in future periods;

       -  obtaining reimbursement for procedures using our devices in some
          foreign markets;

       -  the burden of complying with complex and changing foreign regulatory
          requirements;

       -  longer accounts receivable collection time;

       -  significant currency fluctuations, which could cause our distributors
          to reduce the number of products they purchase from us because the
          cost of our products to them could increase relative to the price they
          could charge their customers;

       -  reduced protection of intellectual property rights in some foreign
          countries; and

       -  contractual provisions governed by foreign laws.

We are substantially dependent on two distributors in our international markets,
and if we lose either distributor or if either distributor significantly reduces
their product demand, our international and total revenues could decline.

     We are substantially dependent on a limited number of significant
distributors in our international markets, and if we lose these distributors and
fail to attract additional distributors, our international revenues could
decline. ITX Corporation, formerly known as Nissho Iwai Corporation, is our
primary distributor in Asia. It accounted for 33 percent of our international
revenues for the six months ended June 30, 2001 and 48 percent of our
international revenues in 2000. M.D.H. s.r.l. Forniture Ospedaliere, our
distributor in Italy, accounted for 22 percent of our international revenues for
the six months ended June 30, 2001 and 17 percent of our international revenues
for 2000. Because international revenues accounted for 53 percent of our total
revenues for the six months ended June 30, 2001 and these two distributors
represented 55 percent of that total, the loss of either distributor or a
significant decrease in unit purchases by either distributor could cause
revenues to decline substantially. If we are unable to attract additional
international distributors, our international revenues may not grow.

Our relationships with third-party distributors could negatively affect our
sales.

                                      -12-



     We sell our products in international markets through third-party
distributors over whom we have limited control, and, if they fail to adequately
support our products, our sales could decline. If our distributors or we
terminate our existing agreements, finding companies to replace them could be an
expensive and time-consuming process and sales could decrease during any
transition period.

If customers in markets outside the United States experience difficulty
obtaining reimbursement for procedures using our products, international sales
could decline.

     Certain of the markets outside the United States in which we sell our
products require that specific reimbursement codes be obtained before
reimbursement for procedures using our products can be approved. As a result, in
countries where specific reimbursement codes are strictly required and have not
yet been issued, reimbursement has been denied on that basis. ITX, our
distributor in Japan, is conducting studies that are necessary to obtain
reimbursement coverage in Japan, but to date has not yet received this approval.
If we are unable to either obtain the required reimbursement codes or develop an
effective strategy to resolve the reimbursement issue, physicians may be
unwilling to purchase our products which could negatively impact our
international revenues.

If third-party payors do not reimburse health care providers for use of the RITA
system, purchases could be delayed and our revenues could decline.

     Physicians, hospitals and other health care providers may be reluctant to
purchase our products if they do not receive substantial reimbursement for the
cost of the procedures using our products from third-party payors, such as
Medicare, Medicaid and private health insurance plans. Hospitals using our
products are currently reimbursed based on established general reimbursement
codes. Because there is no specific reimbursement code for physicians performing
procedures using the RITA system, physicians need to submit a patient case
history and data supporting the applicability of our system to the patient's
condition in order to obtain reimbursement. Each payor then determines whether
and to what extent to reimburse for a medical procedure or product. Payors may
refuse to provide reimbursement for procedures covered by general codes because
the applicability of the code must be determined on a case-by-case basis.
Although we have been notified by the American Medical Association Coding
Committee that specific reimbursement codes for radiofrequency ablation of liver
tumors will be established in 2002, they reserve the right to reverse this
decision. In this case, we would be required to reapply for a specific code.
This process is time consuming and costly and may require us to provide
extensive supporting scientific, clinical and cost-effectiveness data for our
products to the American Medical Association. Even if we were successful in
establishing a new code, a payor still may not reimburse adequately for the
procedure or product. In addition, we believe the advent of fixed payment
schedules has made it difficult to receive reimbursement for disposable
products, even if the use of these products improves clinical outcomes. Fixed
payment schedules typically permit reimbursement for a procedure rather than a
device. If physicians believe that our system will add cost to a procedure but
will not add sufficient offsetting economic or clinical benefits, physician
adoption could be slowed.

You may have a difficult time evaluating our company as an investment because we
have a limited operating history.

     You can only evaluate our business based on a limited operating history
because we began selling the RITA system in 1997. This short history may not be
adequate to enable you to fully assess our ability to achieve market acceptance
of our products and respond to competition.

Any failure to build and manage our direct sales organization may negatively
affect our revenues.

     We have significantly expanded our direct sales force in the United States
over the past twelve months and plan to continue to increase the domestic direct
sales force in the future. There is intense competition for skilled sales and
marketing employees, especially for people who have experience selling
disposable devices and generators to the physicians in our target market, and we
may be unable to hire skilled individuals to sell our products. Any inability to
build and effectively manage our direct sales force could negatively impact our
growth.

We depend on key employees in a competitive market for skilled personnel and
without additional employees, we cannot grow or achieve profitability.

     We are highly dependent on the principal members of our management,
operations and research and development staff. Our future success will depend in
part on the continued service of these individuals and our ability to identify,
hire and retain additional personnel, including sales and marketing staff. The
market for qualified management personnel in Northern California, where our
offices are located, is extremely competitive and is expected to continue to be
highly competitive. Because the environment for good personnel is so
competitive, costs related to compensation may increase significantly. If we are
unable to attract and retain the personnel we need to support and grow our
business, our business will suffer.

                                      -13-



We may be subject to costly and time-consuming product liability actions.

     We manufacture medical devices that are used on patients in both minimally
invasive and open surgical procedures and, as a result, we may be subject to
product liability lawsuits. To date, we have not been subject to a product
liability claim; however, any product liability claim brought against us, with
or without merit, could result in the increase of our product liability
insurance rates or the inability to secure coverage in the future. In addition,
we could have to pay any amount awarded by a court in excess of policy limits.
Finally, even a meritless or unsuccessful product liability claim could be time
consuming and expensive to defend and could result in the diversion of
management's attention from managing our core business.

Any failure in our physician training efforts could result in lower than
expected product sales.

     It is critical to our sales effort to train a sufficient number of
physicians and to instruct them properly in the procedures that utilize our
products. We have established formal physician training programs and rely on
physicians to devote adequate time to understanding how and when our products
should be used. If physicians are not properly trained, they may misuse or
ineffectively use our products. This may result in unsatisfactory patient
outcomes, patient injury and related liability or negative publicity that could
have an adverse effect on our product sales.

We may incur significant costs related to a class action lawsuit due to the
likely volatility of our stock.

     Our stock price may fluctuate for a number of reasons including:

       -  failure of the public market to support the valuation established in
          our initial public offering;

       -  our ability to successfully commercialize our products;

       -  announcements regarding patent litigation or the issuance of patents
          to us or our competitors;

       -  quarterly fluctuations in our results of operations;

       -  announcements of technological or competitive developments;

       -  regulatory developments regarding us or our competitors;

       -  acquisitions or strategic alliances by us or our competitors;

       -  changes in estimates of our financial performance or changes in
          recommendations by securities analysts; and

       -  general market conditions, particularly for companies with small
          market capitalizations.

     Securities class action litigation is often brought against a company after
a period of volatility in the market price of its stock. If our future quarterly
operating results are below the expectations of securities analysts or
investors, the price of our common stock would likely decline. Stock price
fluctuations may be exaggerated if the trading volume of our common stock is
low. Any securities litigation claims brought against us could result in
substantial expense and divert management's attention from our core business.

If we fail to support our anticipated growth in operations, our business could
suffer.

     If we fail to execute our sales strategy and develop further our products,
our business could suffer. To manage anticipated growth in operations, we must
increase our quality assurance staff for both our generators and our disposable
devices and expand our manufacturing staff and facility for our disposable
devices. Our systems, procedures and controls may not be adequate to support our
expected growth in operations.

We have limited experience manufacturing our disposable devices in substantial
quantities, and if we are unable to hire sufficient additional personnel,
purchase additional equipment or are otherwise unable to meet customer demand
our business could suffer.

     To be successful, we must manufacture our products in substantial
quantities in compliance with regulatory requirements at acceptable costs. If we
do not succeed in manufacturing quantities of our disposable devices that meet
customer demand, we could

                                      -14-



lose customers and our business could suffer. At the present time, we have
limited high-volume manufacturing experience. Our manufacturing operations are
currently focused on the in-house assembly of our disposable devices. As we
increase our manufacturing volume and the number of product designs for our
disposable devices, the complexity of our manufacturing processes will increase.
Because our manufacturing operations are primarily dependent upon manual
assembly, if demand for our system increases we will need to hire additional
personnel and may need to purchase additional equipment. If we are unable to
sufficiently staff our manufacturing operations or are otherwise unable to meet
customer demand for our products, our business could suffer.

We are dependent on one supplier as the only source of a component that we use
in our disposable devices, and any disruption in the supply of this component
could negatively affect our revenues.

     Because there is only one supplier that provides us with a component that
we include in our disposable devices, a disruption in the supply of this
component could negatively affect revenues. This supplier is the only source of
this component. If we were unable to remedy a disruption in supply of this
component within twelve months, we could be required to redesign the handle of
our disposable devices, which could divert engineering resources from other
projects or add to product costs. In addition, a new or supplemental filing with
applicable regulatory authorities may require clearance prior to our marketing a
product containing new materials. This clearance process may take a substantial
period of time, and we may be unable to obtain necessary regulatory approvals
for any new material to be used in our products on a timely basis, if at all.
This could also create supply disruptions that could negatively affect our
business.

We are dependent on third-party contractors for the supply of our generators,
and any failure to deliver generators to us could result in lower than expected
revenues.

     One third-party supplier currently manufactures, to our specifications, one
of the generators we sell. There is only one other third-party contractor who we
have used who could readily assume this manufacturing function. Two third-party
suppliers produce the other generator we sell. We have agreements with both of
these suppliers. Any delay in shipments of generators to us could result in our
failure to ship generators to customers and could negatively affect revenues.

Complying with the FDA and other domestic and international regulatory
authorities is an expensive and time-consuming process, and any failure to
comply could result in substantial penalties.

     We are subject to a host of federal, state, local and international
regulations regarding the manufacture and marketing of our products. In
particular, our failure to comply with FDA regulations could result in, among
other things, seizures or recalls of our products, an injunction, substantial
fines and/or criminal charges against our employees and us. The FDA's medical
device reporting regulations require us to report any incident in which our
products may have caused or contributed to a death or serious injury, or in
which our products malfunctioned in a way that would be likely to cause or
contribute to a death or serious injury if the malfunction recurred.

     Sales of our products outside the United States are subject to foreign
regulatory requirements that vary from country to country. The time required to
obtain approvals from foreign countries may be longer than that required for FDA
approval or clearance, and requirements for foreign licensing may differ from
FDA requirements. For example, some of our newer products have not received
approval in Japan. Any failure to obtain necessary regulatory approvals for our
new products in foreign countries could negatively affect revenues.

Product introductions or modifications may be delayed or canceled as a result of
the FDA regulatory process, which could cause our revenues to be below
expectations.

     Unless we are exempt, we must obtain the appropriate FDA approval or
clearance before we can sell a new medical device in the United States. This can
be a lengthy and time-consuming process. To date, all of our products have
received clearances from the FDA through premarket notification under Section
510(k) of the Federal Food, Drug and Cosmetic Act. However, if the FDA requires
us to submit a new premarket notification under Section 510(k) for modifications
to our existing products, or if the FDA requires us to go through a lengthier,
more rigorous examination than we now expect, our product introductions or
modifications could be delayed or canceled which could cause our revenues to be
below expectations. The FDA may determine that future products will require the
more costly, lengthy and uncertain premarket approval process. In addition,
modifications to medical device products cleared via the 510(k) process may
require a new 510(k) submission. We have made minor modifications to our system.
Using the guidelines established by the FDA, we have determined that some of
these modifications do not require us to file new 510(k) submissions. If the FDA
disagrees with our determinations, we may not be able to sell the RITA system
until the FDA has cleared new 510(k) submissions for these modifications. In
addition, we intend to request additional label indications, such as approvals
or clearances for the ablation of tumors in additional organs, including lung,
bone and breast, for our current

                                      -15-



products. The FDA may either deny these requests outright, require additional
extensive clinical data to support any additional indications or impose
limitations on the intended use of any cleared product as a condition of
approval or clearance. Therefore, obtaining necessary approvals or clearances
for these additional applications could be an expensive and lengthy process.

We may need to raise additional capital in the future resulting in dilution to
our stockholders.

     We may need to raise additional funds for our business operations and to
execute our business strategy. We may seek to sell additional equity or debt
securities or to obtain an additional credit facility. The sale of additional
equity or convertible debt securities could result in additional dilution to our
stockholders. If additional funds are raised through the issuance of debt
securities, these securities could have rights that are senior to holders of
common stock and could contain covenants that would restrict our operations. Any
additional financing may not be available in amounts or on terms acceptable to
us, if at all.

Our executive officers and directors own a large percentage of our voting stock
and could exert significant influence over matters requiring stockholder
approval.

     Because our executive officers and directors, and their respective
affiliates, own approximately 29 percent of our outstanding common stock, these
stockholders may, as a practical matter, be able to exert significant influence
over matters requiring approval by our stockholders, including the election of
directors and the approval of mergers or other business combinations. This
concentration of voting stock could have the effect of delaying or preventing a
change in control.

Our certificate of incorporation, our bylaws, Delaware law and our stockholder
rights plan contain provisions that could discourage a takeover.

     Provisions of our certificate of incorporation, our bylaws, Delaware law
and our stockholder rights plan contain provisions that may discourage, delay or
prevent a merger or acquisition that a stockholder may consider favorable.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

     Our market risk disclosures have not changed significantly from those set
forth in Management's Discussion and Analysis of Financial Condition and Results
of Operations in our Form 10-K filing dated March 27, 2001.

PART II. OTHER INFORMATION


Item 1.  Legal Proceedings.

     Our legal proceedings disclosures have not changed significantly from those
set forth in our most recent Report on Form 10-Q. See Item 1. Legal Proceedings
in our Report on Form 10-Q dated May 11, 2001.

Item 2.  Changes in Securities and Use of Proceeds

     On August 1, 2000, we completed our initial public offering of 3,600,000
common shares at a price of $12.00 per share, raising approximately $39.0
million net of underwriting discounts, commissions and other offering costs. The
managing underwriters were Salomon Smith Barney and Robertson Stephens. We
intend to use the proceeds of the offering to expand sales, marketing, physician
and patient awareness programs, to continue product development and clinical
research programs, to repay debt and to fund general corporate purposes
including working capital. Additionally, we may use the proceeds of the offering
to fund the acquisition of complementary businesses, products or technologies,
although there are no current agreements or negotiations with respect to any
specific transaction.
