<P align="left"><FONT size="2">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<I>TOCOSOL Paclitaxel (paclitaxel injectable emulsion; S-8184). </I>Our first
product utilizing the TOCOSOL drug delivery technology is a ready-to-administer
injectable paclitaxel emulsion formulation. Paclitaxel is the active
ingredient in one of the world&#146;s leading cancer drugs, Taxol&#174;, which is
approved in the U.S. for the treatment of breast, ovarian and non-small cell
lung cancers and Kaposi&#146;s sarcoma. We have concluded a Phase 1 study for
TOCOSOL Paclitaxel and the product is currently under study in Phase 2 clinical
trials to evaluate safety and efficacy in non-small cell lung, ovarian, and
bladder cancers. A Phase 2 trial in colorectal cancer was terminated in
October 2002 due to insufficient indications of efficacy. We have also
demonstrated that TOCOSOL Paclitaxel can be administered to patients in 15
minutes as a concentrated emulsion, instead of the typical three-hour infusion
that is required with the currently marketed paclitaxel products. We announced
the issuance of the initial United States patent covering TOCOSOL Paclitaxel
and our TOCOSOL drug delivery technology platform in October 2002 and a second
in November 2002.
</FONT>
<P align="left"><FONT size="2">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We concluded a Phase 1 study for TOCOSOL Paclitaxel in August 2002 after
enrolling a total of 37 evaluable patients. The objectives of the Phase 1
study were to estimate the maximum tolerated dose of TOCOSOL Paclitaxel in
patients with advanced cancer, and to evaluate the safety of repeated doses of
TOCOSOL Paclitaxel given every 3&nbsp;weeks to such patients.
</FONT>
<P align="left"><FONT size="2">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In the Phase 1 study, 30 patients of the 37 enrolled patients were treated
at doses ranging from 175 mg/m<SUP>2</SUP> to 225 mg/m<SUP>2</SUP> every three weeks. The maximum
tolerated dose (MTD)&nbsp;in the Phase 1 study was estimated to be 200 mg/m<SUP>2</SUP> every
three weeks, similar to the approved dose of Taxol&#174; of 175 mg/m<SUP>2</SUP> every three
weeks. TOCOSOL Paclitaxel was generally well tolerated in all patients
treated. All patients in the Phase 1 study had advanced cancers refractory to
previous therapies or for which no standard therapy existed. Five patients

<P align="left"><FONT size="2"> types of cancers had objective partial responses (estimated reduction in
tumor cross-sectional area <u>&#62;</u> 50% for at least 4&nbsp;weeks) during the course of
the study, including four patients who had previously been treated with other
taxane chemotherapies. Dose limiting toxicities included myalgia (muscle
aches), fatigue, and neutropenia (low white cell count). No Grade 3 or Grade 4
neuropathy (damage to the peripheral nerves resulting in altered sensation) was
seen at or below the estimated MTD levels.
</FONT>
<P align="left"><FONT size="2">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We initiated four Phase 2 studies for TOCOSOL Paclitaxel in March of 2002.
The Phase 2 trials are designed to evaluate the safety and efficacy of TOCOSOL
Paclitaxel in specific tumor types. Our goal is to estimate the efficacy of
TOCOSOL Paclitaxel in selected tumor types and to quickly determine the
indications in which the product may show the greatest efficacy. The Phase 2
studies are evaluating TOCOSOL Paclitaxel in non-small cell lung, ovarian and
bladder cancers using weekly dosing of the product. A study in colorectal
cancer was closed to enrollment in October 2002, due to insufficient
indications of efficacy in that disease. These are single agent, open label
studies enrolling patients who have had progressive disease despite prior
chemotherapy but who have not previously had taxane chemotherapy. Each Phase 2
study began with a dose escalation phase to estimate the MTD of TOCOSOL
Paclitaxel using weekly doses of 80, 100 and 120 mg/m<SUP>2</SUP>, after which the number
of additional patients at the estimated MTD was increased sufficiently to allow
appropriate statistical analysis of efficacy.
</FONT>
<P align="left"><FONT size="2">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We have completed the dose escalation stage for all of the Phase 2
studies. The weekly MTDs estimated for TOCOSOL Paclitaxel were 120 mg/m<SUP>2</SUP> in
the non-small cell lung, ovarian and colorectal studies and 100 mg/m<SUP>2</SUP> in the
bladder study. These weekly doses of TOCOSOL Paclitaxel represent cumulative
doses of 300 mg/m<SUP>2</SUP> to 360 mg/m<SUP>2</SUP> over each three-week period. To date, the
incidence of Grade 3 or Grade 4 neutropenia across all studies is 28%, which
compares favorably to what has been seen following treatment with Taxol&#174; in
similar patient populations. The incidence of Grade 3 peripheral neuropathy is
7% (no patients have experienced Grade 4 peripheral neuropathy), which also
compares favorably to the reported experience with approved taxane products.
</FONT>
<P align="left"><FONT size="2">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;As of February 2003, 119 patients have been enrolled in the Phase 2
studies, including 23 in the ovarian study, 43 in the non-small cell lung
study, 25 in the bladder study and 28 in the colorectal study. We have
completed enrollment in the non-small cell lung cancer study and continue to
enroll additional patients in the ovarian and bladder cancer studies. In the
ovarian cancer study, 19 of the 23 patients enrolled are now evaluable for
anti-tumor effect. Six of the patients were reported as having objective
partial responses (estimated reduction in tumor cross-sectional area <u>&#62;</u> 50%
for at least 4&nbsp;weeks) and another six were reported as having stable disease
(no increase in tumor size). In the non-small cell lung cancer study, 22 of
the 43 patients enrolled are evaluable for anti-tumor effect. Four of the 22
patients have had objective partial responses and another 13 were reported as
having stable disease. In the bladder cancer study, 15 of the 25 patients
enrolled are evaluable for anti-tumor effect. Five of the patients were
reported as having objective partial responses and another 10 were reported as
having stable disease. In the colorectal cancer study, 29 patients have been
enrolled, treated and assessed. One patient had a partial response. Based on
pre-defined criteria regarding indications of efficacy, the colorectal study
was closed to enrollment in October 2002. The results of the Phase 2 clinical
trials are preliminary at this time and may or may not be indicative of the
final results upon completion of the studies.
</FONT>
<P align="left"><FONT size="2">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Given the progress to date in the clinical program with TOCOSOL
Paclitaxel, we are focusing on regulatory strategies that maximize the value of
the product and minimize the time required to bring it to market. We are
currently consulting with the FDA to seek concurrence with our regulatory
strategy. Following clarification from the FDA, we will be prepared to begin
the registrational trials that will serve as the basis for approval for our New
Drug Application.

second product utilizing the TOCOSOL drug delivery technology is a novel
injectable formulation of camptothecin. There are currently two marketed
water-soluble or hydrophilic camptothecin analogs that are based on a
chemically modified camptothecin molecule. Irinotecan&#174; is indicated for
treatment of colorectal cancer and Topotecan&#174; is indicated for treatment of
ovarian and non-small cell lung cancer. We filed an Investigational New Drug
Exemption application, or IND, for TOCOSOL Camptothecin in late 2002. We are

<P align="left"><FONT size="2">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Consistent with our strategy to develop a pipeline of proprietary new
formulations of drug candidates, we are evaluating a variety of therapeutic
drug formulations utilizing our TOCOSOL drug delivery technology. We currently
have formulations under investigation in areas that target cancer and other
serious diseases. Our research and development efforts on these are
preliminary and we cannot give any assurance that any of these compounds will

<P align="left"><FONT size="2"><B>Market Overview</B></FONT>

<P align="left"><FONT size="2">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Our products are for the most part in the early to middle stages of
development and it is difficult to evaluate the potential markets for these
products as the areas of potential application are diverse and specific
applications are yet to be determined. Overall, we operate in the drug
delivery market sector. The drug delivery market is reported to be nearly $40
billion. Of that, approximately 75% is dedicated to the development of oral
and injectable dosage forms. Our initial products under development would
address a small fraction of this market. Drug delivery technology serves an
increasingly important need in pharmaceutical development. The major
pharmaceutical companies face an extremely competitive market, are under
increasing pressure to introduce new products, and are facing loss of patent
protection for a significant number of major revenue-producing drugs in their
portfolios. We believe that new drug delivery technologies provide
opportunities for overcoming formulation challenges with promising active
pharmaceutical ingredients, for establishing product differentiation, for
extending product life cycles, and for providing additional patent protection
for key products.

<P align="left"><FONT size="2">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Our lead product, TOCOSOL Paclitaxel, is a cancer therapy drug. It is
currently under evaluation in Phase 2 clinical studies. Paclitaxel, the active
ingredient in TOCOSOL Paclitaxel, is part of the taxane class of chemotherapy
drugs, which generate annual worldwide sales in excess of $2&nbsp;billion. Cancer
is characterized by rapid, uncontrolled cell division resulting in the growth
of an abnormal mass of cells generally referred to as a tumor. Cancerous tumors
can arise in almost any tissue or organ and cancer cells, if not eradicated,
spread, or metastasize, throughout the body. As these tumors grow, they cause
damage to the surrounding tissue and organs and commonly result in death if
left untreated. Cancer is believed to occur as a result of a number of
hereditary and environmental factors. According to the American Cancer
Society, cancer is the second leading cause of death in the United States and
accounts for approximately one in every four deaths. Approximately 557,000
Americans are expected to die of cancer in 2003. The National Institutes of
Health estimated the direct medical cost of cancer to be $61&nbsp;billion in 2002.

<P align="left"><FONT size="2">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Because of the number of research projects we have ongoing at any one
time, and the ability to utilize resources across several projects, the
majority of our research and development costs are not directly tied to any
individual project and are allocated among multiple projects. We manage our
projects by reviewing scientific data and by supplementing this data with our
cost allocations. Our cost allocations are based primarily on human resource
time incurred on each project. The costs allocated to a project as a result do
not necessarily reflect the actual costs of the project. Accordingly, we do
not maintain actual cost incurred information for our projects on a
project-by-project basis. Costs attributed to research and preclinical
projects largely represent our pipeline generating activities. Costs
associated with clinical development programs represent the advancement of
these activities into product candidates. See Item&nbsp;7. &#147;Management&#146;s Discussion
and Analysis of Financial Condition and Results of Operations&#148; for further

drug-manufacturing establishment must be registered or licensed by the FDA for
each product that is manufactured at that facility. U.S. manufacturing
establishments are subject to inspections by the FDA and by other federal,
state and local agencies and must comply with Good Manufacturing Practices, or
GMP, requirements applicable to the production of pharmaceutical drug products.
</FONT>

an independent Institutional Review Board or Ethics Committee who consider,
among other things, ethical factors, informed consent documents, the safety of
human subjects and the possible liability of the institution conducting a
clinical study. The Institutional Review Board or Ethics Committee may require
changes in protocol, which may delay initiation or completion of the study.
</FONT>
<P align="left"><FONT size="2">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Clinical trials typically are conducted in three sequential phases,
although the phases may overlap. In Phase 1, the initial introduction of the
drug to humans, the drug is tested for safety and clinical pharmacology. Phase
2 trials involve more detailed evaluation of the safety and efficacy of the
drug in patients with the disease or condition being studied. Phase 3 trials
consist of large scale evaluations of safety and efficacy and typically require
multiple clinical trial sites.
</FONT>
<P align="left"><FONT size="2">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The process of completing clinical testing and obtaining FDA approval for
a new product takes a number of years and requires the expenditure of
substantial resources. The FDA may grant an unconditional approval of a drug
for a particular indication or may grant approval conditioned on further
post-marketing clinical trials. The FDA also may conclude that the submission
is not adequate to support an approval and may require further clinical and
preclinical testing, re-submission of the NDA, and further review. Even after
initial FDA approval has been obtained, further studies may be required to
provide additional data or to gain approval for the use of a product for
clinical indications other than those for which the product was approved
initially. Also, the FDA may require post-market testing and surveillance
programs to monitor the drug&#146;s side effects.
</FONT>
<P align="left"><FONT size="2">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Marketing of pharmaceutical products outside of the U.S. is subject to
regulatory requirements that vary from country to country. In the European
Union, the general trend has been towards coordination of the common standards
for clinical testing of new drugs. Centralized approval in the European Union
is coordinated through the European Medicines Evaluation Agency, or EMEA.
</FONT>
<P align="left"><FONT size="2">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The level of regulation outside of the U.S. and European Union varies
widely. The time required to obtain regulatory approval from regulatory
agencies in each country may be longer or shorter than that required for FDA or
EMEA approval. In addition, in certain markets, reimbursement may be subject
to governmentally mandated prices.

<P align="left"><FONT size="2">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Many of the chemicals and compounds used in our research and development
efforts are classified as hazardous materials under applicable federal, state
and local environmental laws and regulations. We are subject to regulations
under state and federal law regarding occupational safety, laboratory

<P align="left"><FONT size="2">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The healthcare industry in general is characterized by extensive research
efforts, rapid technological change and intense competition. We believe that
other pharmaceutical companies will compete with us in areas of research and
development, acquisition of products and technology licenses, and the
manufacturing and marketing of products that could potentially compete with
ours. Several other companies are developing paclitaxel reformulations with a
goal of delivering a more effective and tolerable therapy than the approved
products. Some of these product candidates are further in development than
TOCOSOL Paclitaxel and may achieve regulatory approval before TOCOSOL
Paclitaxel. We expect that competition will be based on safety, efficacy, ease
of administration, breadth of approved indications, price, reimbursement and
physician and patient acceptance.

<P align="left"><FONT size="2">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We consider the protection of our technology to be important to our
business. In addition to seeking U.S. patent protection for many of our
inventions, we are also seeking patent protection in other countries in order
to protect our proprietary rights to inventions. We also rely upon trade
secrets, know-how, continuing technological innovations and licensing
opportunities to develop and maintain our competitive position.
</FONT>
<P align="left"><FONT size="2">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Our success will depend, in part, on our ability to obtain patents, defend
patents and protect trade secrets. To date, we have filed 23 patent
applications in the U.S. pertaining to our TOCOSOL drug delivery technology and
related systems as well as counterpart filings in Europe and key countries in
Asia and Latin America. During 2002, the United States Patent and Trademark
Office issued two patents to us related to TOCOSOL Paclitaxel and the TOCOSOL
Drug Delivery System. All other patent applications are currently in process
and have not been issued by the United States Patent and Trademark Offices or
foreign counterpart agencies, although we have received notice of allowable
claims in certain applications.
</FONT>
<P align="left"><FONT size="2">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The patent position of medical and pharmaceutical companies is highly
uncertain and involves complex legal and factual questions. There can be no
assurance that any claims which are included in pending or future patent
applications will be issued, that any issued patents will provide us with
competitive advantage or will not be challenged by third parties, or that the
existing or future patents of third parties will not have an adverse effect on
our ability to commercialize our products. Furthermore, there can be no
assurance that other companies will not independently develop similar products,
duplicate any of our products or design around patents that may be issued to
us. Litigation or administrative proceedings may be necessary to enforce any
patents issued to us or to determine the scope and validity of others&#146;
proprietary rights in court or administrative proceedings. A significant
portion of our drug delivery products is based upon extending the effective
patent life of existing products through the use of our proprietary technology.
See &#147;Certain Factors That May Affect Our Business and Future Results &#150; <I>If we

<P align="left"><FONT size="2">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<I>If we fail to develop products, then we may never realize revenue from
product commercialization.</I>
</FONT>
<P align="left"><FONT size="2">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;A key element of our business strategy is to utilize our technologies for
the development and commercialization of products that utilize our drug
delivery technology. The initial application of our drug delivery technology,
TOCOSOL, is a novel approach to the formulation of water insoluble compounds
for therapeutic applications. Significant expenditures in additional research
and development, clinical testing, regulatory, manufacturing, and sales and
marketing activities will be necessary in order for us to demonstrate the
efficacy of our products, or commercialize any products developed with our
technology. There can be no assurance that TOCOSOL Paclitaxel or any of our
other current products under development or any future products will be safe or
efficacious.
</FONT>
<P align="left"><FONT size="2">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Even if we are successful in developing our products, there is no
assurance that such products will receive regulatory approval or that a
commercially viable market will develop. While it is our strategy to develop
additional products under our drug delivery technology by entering into
feasibility study agreements with companies who own active compounds, there can
be no assurance that we will enter into any feasibility studies. Moreover,
there can be no assurance that these feasibility studies will result in
development or license agreements. Without feasibility studies or development
or license agreements, we may need to scale back or terminate our efforts to
develop other products using our drug delivery technology.

</FONT>
<P align="left"><FONT size="2">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We are subject to uncertain governmental regulatory requirements and a
lengthy approval process for our products prior to any commercial sales of our
products. The development and commercial use of our products are regulated by
the U.S. Food and Drug Administration, or FDA, the European Medicines
Evaluation Agency, or EMEA, and comparable regulatory agencies in other
countries. The regulatory approval process for new products is lengthy and
expensive. Before we can file an application with the FDA and comparable
international agencies, the product candidate must undergo extensive testing,
including animal studies and human clinical trials that can take many years and
require substantial expenditures. Data obtained from such testing may be
susceptible to varying interpretations, which could delay, limit or prevent
regulatory approval. In addition, changes in regulatory policy for product
approval may cause additional costs in our efforts to secure necessary
approvals.
</FONT>
<P align="left"><FONT size="2">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Our drug delivery products are subject to significant uncertainty because
they are in the early stages of development and are subject to regulatory
approval. We filed an Investigational New Drug Exemption application, or IND,
with the FDA for TOCOSOL Paclitaxel in September 2000 and completed the Phase 1
clinical study for this product in August 2002. In March 2002, we initiated
the first four Phase 2 clinical trials for TOCOSOL Paclitaxel. Included in
this first group of Phase 2 clinical trials was a trial in colorectal cancer
that was terminated in October 2002 due to insufficient indications of
efficacy. There can be no assurance that the clinical studies will demonstrate
that TOCOSOL Paclitaxel will be safe or efficacious or that we will file a new
drug application. We are also currently engaged in the development of a
formulation of camptothecin using our TOCOSOL drug delivery technology. We
filed an IND for TOCOSOL Camptothecin with the FDA in late 2002 and are
currently in the process of responding to certain questions from the FDA. The
results of pre-clinical and clinical testing of our products are uncertain and
regulatory approval of our products may take longer or be more expensive than
anticipated, which could have a material adverse affect on our business,
financial condition and results of operations. We cannot predict if or when
any of our products under development will be commercialized.

<P align="left"><FONT size="2">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Several other companies are developing paclitaxel reformulations with a
goal of delivering a more effective and tolerable therapy than the approved
paclitaxel products. Some of these products are further in development than
TOCOSOL Paclitaxel and may achieve regulatory approval before our product. In
addition, Aventis has a docetaxel product, Taxotere&#153;, which is similar to
paclitaxel and is marketed for the treatment of breast and non-small cell lung
cancers. As a result of the increased competition, the price for paclitaxel
products has been falling.
</FONT>
<P align="left"><FONT size="2">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Many of our competitors and potential competitors have substantially
greater financial, technical and human resources than we do and have
substantially greater experience in developing products, obtaining regulatory
approvals and marketing and manufacturing medical products. Accordingly, these
competitors may succeed in obtaining FDA approval for their products more
rapidly than us. In addition, other technologies or products may be developed
that have an entirely different approach that would render our technology and
products noncompetitive or obsolete. If we fail to compete effectively, it
would have a material adverse effect on our business, financial condition and
results of operations.

adversely impact our ability to commercialize our products.</I>
</FONT>
<P align="left"><FONT size="2">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We currently rely on third parties to supply the chemical ingredients
necessary for our drug delivery products. Currently, Indena SpA is our primary
supplier of paclitaxel, the main ingredient in TOCOSOL Paclitaxel. The
chemical ingredients for our products are manufactured by a limited number of
vendors. The inability of these vendors to supply medical-grade materials to
us could delay the manufacturing of, or cause us to cease the manufacturing of
our products. We also rely on third parties to manufacture our products for
research and development and clinical trials. Gensia Sicor Pharmaceuticals,
Inc. is our primary manufacturer of TOCOSOL Paclitaxel for clinical studies and
has also agreed to manufacture TOCOSOL Paclitaxel for commercialization. We
previously manufactured clinical supplies of TOCOSOL Paclitaxel at GMP
certified contract laboratories. Suppliers and manufacturers of our products
must operate under GMP regulations, as required by the FDA, and there are a
limited number of contract manufacturers that operate under GMP regulations.
If there are problems associated with the commercial scale-up of TOCOSOL
Paclitaxel, it could delay our research and development efforts as well as the
time it takes to commercialize our products, which could materially adversely
affect our business, financial condition and results of operations.

patents and protect trade secrets. To date, we have two United States patents
issued and 23 patent applications filed in the United States pertaining to our
TOCOSOL drug delivery technology as well as counterpart filings in Europe and
key countries in Asia and Latin America. The patent position of medical and
pharmaceutical companies is highly uncertain and involves complex legal and
factual questions. There can be no assurance that any claims which are
included in pending or future patent applications will be issued, that any
issued patents will provide us with competitive advantages or will not be
challenged by third parties, or that the existing or future patents of third
parties will not have an adverse effect on our ability to commercialize our
products. Furthermore, there can be no assurance that other companies will not
independently develop similar products, duplicate any of our products or design
around patents that may be issued to us. Litigation may be necessary to enforce
any patents issued to us or to determine the scope and validity of others&#146;
proprietary rights in court or administrative proceedings. Any litigation or
administrative proceeding could result in substantial costs to us and
distraction of our management. An adverse ruling in any litigation or
administrative proceeding could have a material adverse effect on our business,
financial condition and results of operations.

</FONT>
<P align="left"><FONT size="2">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;There can be no assurance that patents belonging to competitors will not
require us to alter our products or processes, pay licensing fees or cease
development of our current or future products. Any litigation regarding
infringement could result in substantial costs to us and distraction of our
management, and any adverse ruling in any litigation could have a material
adverse effect on our business, financial condition and results of operations.
Further, there can be no assurance that we will be able to license other
technology that we may require at a reasonable cost or at all. Failure by us
to obtain a license to any technology that we may require to commercialize our
products would have a material adverse effect on our business, financial
condition and results of operations. In addition, to determine the priority of
inventions and the ultimate ownership of patents, we may participate in
interference, reissue or re-examination proceedings conducted by the U.S.
Patent and Trademark Office or in proceedings before international agencies
with respect to any of our existing patents or patent applications or any
future patents or applications, any of which could result in loss of ownership
of existing, issued patents, substantial costs to us and distraction of our

</FONT>
<P align="left"><FONT size="2">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Our ability to successfully commercialize products that we develop will
depend, in part, upon the extent to which reimbursement of the cost of such
products will be available from domestic and international health
administration authorities, private health insurers and other payer
organizations. Third party payers are increasingly challenging the price of
medical and pharmaceutical products and services or restricting the use of
certain procedures in an attempt to limit costs. Further, significant
uncertainty exists as to the reimbursement status of newly approved healthcare
products, and there can be no assurance that adequate third party coverage will
be available.

personnel could have a material adverse effect on our business, financial
condition and results of operations. We do not have employment contracts with
any of our key personnel and we do not maintain insurance policies that would
compensate us for the loss of their services. There can be no assurance that
we will be able to attract and retain such personnel on acceptable terms, if at
all, given the competition for experienced scientists and other personnel among
numerous medical and pharmaceutical companies, universities and research

upon a number of factors, including our historical and anticipated operating
results, preclinical and clinical trial results, market perception of the
prospects for biotechnology companies as an industry sector and general market
and economic conditions, some of which are beyond our control. Factors such as
fluctuations in our financial and operating results, changes in government
regulations affecting product approvals, reimbursement or other aspects of our
or our competitors&#146; businesses, FDA review of our product development
activities, the results of preclinical studies and clinical trials,
announcements of technological innovations or new commercial products by us or
our competitors, developments concerning key personnel and our intellectual
property rights, significant collaborations or strategic alliances and
publicity regarding actual or potential performance of products under
development by us or our competitors could also cause the market price of our
common stock to fluctuate substantially. In addition, the stock market has from
time to time experienced extreme price and volume fluctuations. These broad
market fluctuations may lower the market price of our common stock. Moreover,
during periods of stock market price volatility, share prices of many
biotechnology companies have often fluctuated in a manner not necessarily

may be subject to greater price volatility than the stock market as a whole.

<P align="left"><FONT size="2">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Sonus Pharmaceuticals is a drug reformulation company focusing on the
optimization of therapeutic drugs to treat cancer and other serious disease.
We are developing a number of potential product candidates utilizing our
proprietary TOCOSOL&#153; drug delivery technology. The development of therapeutic
drugs with TOCOSOL may result in products that can be delivered more
conveniently, safely and effectively. Our lead cancer product, TOCOSOL
Paclitaxel, is a novel formulation of paclitaxel; one of the world&#146;s most
widely used anticancer drugs.
</FONT>
<P align="left"><FONT size="2"><B>Results of Operations</B></FONT>

<P align="left"><FONT size="2">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;As of December&nbsp;31, 2002, our accumulated deficit was approximately $40.3
million. We may incur substantial additional operating losses over the next
several years. Such losses have been and may continue to be principally the
result of various costs associated with our discovery, research and development
programs and the purchase of technology. Substantially all of our revenue to
date has resulted from corporate partnerships and licensing arrangements, and
interest income. Our ability to achieve a consistent, profitable level of
operations depends in large part on entering into corporate partnerships for
product discovery, research, development and commercialization, obtaining
regulatory approvals for our products and successfully manufacturing and
marketing our products once they are approved. Even if we are successful in
the aforementioned activities our operations may not be profitable. In
addition, payments under corporate partnerships and licensing arrangements are
subject to significant fluctuations in both timing and amount. Therefore, our
operating results for any period may fluctuate significantly and may not be
comparable to the operating results for any other period.
</FONT>
<P align="left"><FONT size="2"><B><I>Years Ended December&nbsp;31, 2002 and December&nbsp;31, 2001</I></B></FONT>

<P align="left"><FONT size="2">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Historically, our reported revenues have been derived from payments
received under contractual and license agreements with third parties. Revenues
for the year ended December&nbsp;31, 2002 were $25,000 compared to $8.7&nbsp;million in
2001. Revenues from 2001 primarily resulted from the assignment of
substantially all of our ultrasound contrast intellectual property to Nycomed
for $6.5&nbsp;million and payments received under our license agreement with Chugai
of $2.0&nbsp;million. Monetizing the remaining value of the ultrasound contrast
intellectual property was a key goal in 2001 as we transitioned to a drug
delivery strategy. Revenues in 2003 will be dependent on our ability to enter
into new collaborative agreements or licensing arrangements with third parties.
</FONT>
<P align="left"><FONT size="2">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Research and development (R&#038;D) expenses were $9.0&nbsp;million for the year
ended December&nbsp;31, 2002 compared to $5.2&nbsp;million in the prior year. This
planned increase reflects continued activity related to the manufacture,
development and clinical testing of our lead cancer therapy product, TOCOSOL
Paclitaxel, as the drug advances through Phase 2 clinical trials as well as
increased costs to support new product development. We expect R&#038;D expenses to
continue to increase as we continue clinical trials for TOCOSOL Paclitaxel and
advance product development efforts relating to other potential applications of
our drug delivery platform.
</FONT>
<P align="left"><FONT size="2">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;General and administrative expenses were $3.2&nbsp;million for the year ended
December&nbsp;31, 2002, or slightly below the prior year expense of $3.3&nbsp;million.
</FONT>
<P align="left"><FONT size="2">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Total operating expenses in 2003 are expected to be in line with 2002
levels as we continue development of our TOCOSOL drug delivery products. We
estimate that R&#038;D spending will comprise approximately 75% of the

<P align="left"><FONT size="2"> anticipated spending in 2003. A significant portion of the R&#038;D spending
will be devoted to further development of TOCOSOL Paclitaxel including
continued work on the Phase 2 studies and commencement of the registrational
clinical program. These estimates and actual expenses are subject to change
depending on many factors, including unforeseen expansion of study size or
duration, complications in conducting or completing studies, changes in FDA
requirements, increased material costs and other factors. Additionally, we may
be required to reduce our anticipated R&#038;D expenses if additional financing is
not available in 2003.
</FONT>
<P align="left"><FONT size="2">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Interest income, net of interest expense, was $437,000 for the year ended
December&nbsp;31, 2002 compared with $526,000 for the prior year. The decrease in
net interest income was primarily due to lower interest rates during 2002 over
the same period in 2001 and higher interest expense related to increased
capital lease activity in 2002 offset partially by higher cash balances.
</FONT>
<P align="left"><FONT size="2">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Income taxes reflect a one-time tax benefit of $101,000 primarily related
to regulatory changes in federal tax regulations in early 2002. In 2001, we
reported income tax expense of $200,000 related to international withholding
taxes paid on licensing payments received from Chugai.
</FONT>
<P align="left"><FONT size="2"><B><I>Years Ended December&nbsp;31, 2001 and December&nbsp;31, 2000</I></B></FONT>

<P align="left"><FONT size="2">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Revenues for the year ended December&nbsp;31, 2001 were $8.7&nbsp;million compared
to $408,000 in 2000. The increase was primarily the result of the assignment
of substantially all of our ultrasound contrast intellectual property to
Nycomed for $6.5&nbsp;million and payments received under our license agreement with
Chugai of $2.0&nbsp;million.

<P align="left"><FONT size="2">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Research and development (R&#038;D) expenses were $5.2&nbsp;million for the year
ended December&nbsp;31, 2001 compared to $3.7&nbsp;million in 2000. The increase was
primarily related to the further development and Phase 1 study of TOCOSOL
Paclitaxel and the related increase in spending on clinical trials as well as
increases in headcount costs associated with the expansion of our R&#038;D group.
</FONT>
<P align="left"><FONT size="2">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;General and administrative expenses were $3.3&nbsp;million for the year ended
December&nbsp;31, 2001 compared with $3.9&nbsp;million in 2000. The decrease was due
primarily to the reduction of legal costs as a result of the favorable patent
litigation settlement in May 2000.
</FONT>
<P align="left"><FONT size="2">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Interest income, net of interest expense, was $526,000 for the year ended
December&nbsp;31, 2001 compared with $658,000 for 2000. The decrease in net
interest income was primarily due to lower interest rates during 2001 over the
same period in 2000.
</FONT>
<P align="left"><FONT size="2">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;During 2001, International withholding taxes of $200,000 were paid on
licensing payments received from Chugai. In 2000, we reported an income tax
benefit of $176,939 for a refund we received on international withholding taxes
paid in 1995. A valuation allowance had previously been provided for this
balance due to uncertainty of receipt of this refund.
</FONT>
<P align="left"><FONT size="2"><B>Liquidity and Capital Resources</B></FONT>

<P align="left"><FONT size="2">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We have historically financed operations with payments under contractual
agreements with third parties and proceeds from equity financings. In January
2002, we completed a private placement equity financing that raised
approximately $12.5&nbsp;million in net proceeds through the sale of 1.9&nbsp;million
shares of common stock.
</FONT>
<P align="left"><FONT size="2">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;At December&nbsp;31, 2002, we had cash, cash equivalents and marketable
securities of $16.3&nbsp;million compared to $15.1&nbsp;million at December&nbsp;31, 2001.
The increase was primarily due to the $12.5&nbsp;million of net proceeds from the
private placement of common stock and $359,000 in proceeds from the exercise of
stock options, offset in part by the net loss for 2002 of $11.6&nbsp;million.
</FONT>
<P align="left"><FONT size="2">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We expect that our cash requirements will increase in future periods due
to development costs associated with our TOCOSOL drug delivery products. Based
on our current operating plan, including planned clinical trials and other
product development costs including technology transfer costs related to our
manufacturing and supply

<P align="left"><FONT size="2"> agreement, we estimate that existing cash and marketable securities will
be sufficient to meet our cash requirements through approximately the second
quarter of 2004 based on current expense levels. However, if we are unable to
obtain additional financing in 2003, we intend to reduce expenses such that
existing cash resources would last through 2004. We will need additional
funding to complete late stage clinical trials and obtain regulatory approval
of TOCOSOL Paclitaxel and to fund other product development activities beyond
this timeframe. Accordingly, we intend to seek additional funding through
available means, which may include debt and/or equity financing or funding
under additional third party collaborative agreements.

<P align="left"><FONT size="2"><B>Critical Accounting Policies and Estimates</B></FONT>

<P align="left"><FONT size="2">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The preparation of the financial statements requires management to make
estimates and assumptions that affect the reported amounts of liabilities at
the date of the financial statements and the reported amounts of revenue and
expenses during the reporting period. On an on-going basis, management
evaluates its estimates and judgements including those related to revenue
recognition and research and development costs. Management bases its estimates
and judgements on historical experience and on various other factors that are
believed to be reasonable under the circumstances. Actual results may differ
from these estimates under different assumptions or conditions.

<P align="left"><FONT size="2">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In November 2002, the Emerging Issues Task Force (EITF)&nbsp;issued EITF Issue
No.&nbsp;00-21, &#147;Revenue Arrangements with Multiple Deliverables&#148;, which provides
guidance on the timing and method of revenue recognition for sales arrangements
that include the delivery of more than one product or service. EITF 00-21 is
effective prospectively for arrangements entered into in fiscal periods
beginning after June&nbsp;15, 2003. The Company does not expect that the adoption
of EITF 00-21 will have a significant impact on its financial statements.
</FONT>
<P align="left"><FONT size="2">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In June 2002, the Financial Accounting Standards Board (FASB)&nbsp;issued
Statement No.&nbsp;146, &#147;Accounting for Costs Associated with Exit or Disposal
Activities&#148;. The standard addresses financial accounting and reporting for
costs associated with exit or disposal activities and nullifies Emerging Issues
Task Force (EITF)&nbsp;Issue No.&nbsp;94-3, &#147;Liability Recognition for Certain Employee
Termination Benefits and Other Costs to Exit an Activity (including Certain
Costs Incurred in a Restructuring).&#148; Statement No.&nbsp;146 states that a liability
for a cost associated with an exit or disposal activity shall be recognized and
measured initially at its fair value in the period in which the liability is
incurred, except for a liability for one-time termination benefits that are
incurred over a period of time. The standard will apply to the Company
effective for exit or disposal activities initiated after December&nbsp;31, 2002.
The Company does not believe there will be a material effect from the adoption
of this new standard.
</FONT>
<P align="left"><FONT size="2">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On December&nbsp;31, 2002, FASB issued SFAS No.&nbsp;148, Accounting for Stock-Based
Compensation-Transition and Disclosure. SFAS No.&nbsp;148 amends SFAS No.&nbsp;123,
Accounting for Stock-Based Compensation. SFAS No.&nbsp;148 requires accounting
policy note disclosures to provide the method of stock option accounting for
each year presented in the financial statements and, for each year until all
years presented in the financial statements recognize the fair value of
stock-based compensation. Also, SFAS No.&nbsp;148 provides two additional
transition methods that eliminate the ramp-up effect resulting from applying
the expense recognition provisions of SFAS No.&nbsp;123. The transition provisions
and annual statement disclosure requirements of SFAS No.&nbsp;148 are effective for
fiscal years ending after December&nbsp;15, 2002. The interim statement disclosure
requirements are effective for the first interim statement that includes
financial information after December&nbsp;15, 2002. The Company does not believe
there will be a material financial effect from the adoption of this new
standard unless it were to make a change in its accounting policy and account
for stock option grants as compensation expense.
</FONT>
<P align="left"><FONT size="2">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In November 2002, the FASB issued FASB Interpretation No.&nbsp;45 (&#147;FIN 45&#148;),
&#147;Guarantor&#146;s Accounting and Disclosure Requirements for Guarantees, Including
Indirect Guarantees of Indebtedness of Others, an interpretation of FASB
Statements No.&nbsp;5, 57 and 107 and Rescission of FASB Interpretation No.&nbsp;34.&#148;
FIN 45 clarifies the requirements of SFAS No.&nbsp;5, &#147;Accounting for
Contingencies,&#148; relating to the guarantor&#146;s accounting for, and disclosure of,
the issuance of certain types of guarantees. The disclosure provisions of FIN
45 are effective for financial statements of periods that end after December
15, 2002. However, the provisions for initial recognition and measurement are
effective on a prospective basis for guarantees that are issued or modified
after December&nbsp;31, 2002. The Company is still assessing the potential impact
on its results from operations from the adoption of FIN 45.
</FONT>
<P align="left"><FONT size="2">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In January 2003, the FASB issued FASB Interpretation No.&nbsp;46 (&#147;FIN 46&#148;),
&#147;Consolidation of Variable Interest Entities.&#148; FIN 46 clarifies the
application of Accounting Research Bulletin No.&nbsp;51, &#147;Consolidated Financial
Statements,&#148; to certain entities in which equity investors do not have the
characteristics of a controlling financial interest or do not have sufficient
equity at risk for the entity to finance its activities without additional
subordinated financial support from other parties. FIN 46 applies immediately
to variable interest entities created after January&nbsp;31, 2003, and to variable
interest entities in which an enterprise obtains an interest after that date.
It applies in the first fiscal year or interim period beginning after June&nbsp;15,
2003, to variable interest entities in which an enterprise holds a variable
interest that it acquired before February&nbsp;1, 2003. FIN 46 applies to public
enterprises as of the beginning of the applicable interim or annual period.
The Company does not believe there will be a material effect upon its financial
condition or results of operations from the adoption of the provisions of FIN
46.

</FONT>
<P align="left"><FONT size="2">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We have audited the accompanying balance sheets of Sonus Pharmaceuticals,
Inc. as of December&nbsp;31, 2002
and 2001, and the related statements of operations, stockholders&#146; equity and
cash flows for each of the three years in the period ended December&nbsp;31, 2002.
These financial statements are the responsibility of the Company&#146;s management.
Our responsibility is to express an opinion on these financial statements based
on our audits.
</FONT>
<P align="left"><FONT size="2">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We conducted our audits in accordance with auditing standards generally
accepted in the United States. Those standards require that we plan and perform
the audit to obtain reasonable assurance about whether the financial statements
are free of material misstatement. An audit includes examining, on a test
basis, evidence supporting the amounts and disclosures in the financial
statements. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.
</FONT>
<P align="left"><FONT size="2">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Sonus Pharmaceuticals, Inc.
at December&nbsp;31, 2002 and 2001, and the results of its operations and its cash
flows for each of the three years in the period ended December&nbsp;31, 2002, in
conformity with accounting principles generally accepted in the United States.

<P align="left"><FONT size="2"><B><I>Business Overview</I></B></FONT>

<P align="left"><FONT size="2">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Sonus Pharmaceuticals is applying its novel TOCOSOL&#153; drug delivery
technology to formulate therapeutic drugs to make them easier to administer,
safer and more effective. Our lead product, TOCOSOL Paclitaxel, is a novel
formulation of paclitaxel, one of the world&#146;s most widely used anticancer
drugs. We are also developing a number of additional product candidates
utilizing the TOCOSOL technology in applications to treat cancer and other
serious disease.
</FONT>
<P align="left"><FONT size="2"><B><I>Cash and Cash Equivalents</I></B></FONT>

<P align="left"><FONT size="2">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Cash and cash equivalents consist of highly liquid investments with a
maturity of three months or less at the date of purchase.
</FONT>
<P align="left"><FONT size="2"><B><I>Marketable Securities</I></B></FONT>

<P align="left"><FONT size="2">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Company classifies the marketable securities portfolio as
available-for-sale, and such securities are stated at fair value based on
quoted market prices, with the unrealized gains and losses included as a
component of accumulated other comprehensive loss. Interest earned on
securities available-for-sale is included in interest income. The carrying
value of debt securities in this category is adjusted for amortization of
premiums and accretion of discounts to maturity. Such amortization and
accretion are included in interest income. Realized gains and losses and
declines in value judged to be other than temporary on securities
available-for-sale also are included in interest income. The cost of
securities sold is based on the specific identification method.
</FONT>
<P align="left"><FONT size="2"><B><I>Concentrations of Credit Risk</I></B></FONT>

<P align="left"><FONT size="2">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Company invests its excess cash in accordance with investment
guidelines, which limit the credit exposure to any one financial institution
and to any one type of investment, other than securities issued by the U.S.
government. The guidelines also specify that the financial instruments are
issued by institutions with strong credit ratings. These securities are
generally not collateralized and mature within one year.
</FONT>
<P align="left"><FONT size="2"><B><I>Revenue Recognition</I></B></FONT>

<P align="left"><FONT size="2">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Since inception, the Company has generated revenues from collaborative
agreements, licensing fees and from the assignment of developed and patented
technology. Revenue is recorded as earned based on the performance
requirements of the contract, generally as the services are performed. The
Company recognizes revenue from non-refundable, upfront license fees and
proceeds from the assignment of technology when delivery has occurred and no
future obligations exist. Royalties from licensees are based on third-party
sales and recorded as earned in accordance with contract terms, when
third-party results are reliably measured and collection is reasonably assured.
Payments received for which the earnings process is not complete are
classified as deferred revenue.
</FONT>
<P align="left"><FONT size="2"><B><I>Research and Development Costs</I></B></FONT>

<P align="left"><FONT size="2">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Research and development costs including personnel costs, supplies,
depreciation and other indirect costs are expensed as incurred. In instances
where the Company enters into collaborative agreements with third parties,
costs are expensed the earlier of when amounts are due or when services are
performed. In instances where the Company enters into agreements with third
parties for research and/or clinical trial activities, costs are expensed the
earlier of when amounts are due or when services are performed.

<P align="left"><FONT size="2">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Equipment, furniture and leasehold improvements are stated at cost.
Depreciation of equipment is provided using the straight-line basis over three
to five years, the estimated useful life of the assets. Leasehold improvements
are amortized over the lesser of the economic useful lives of the improvements
or the term of the related lease. Repair and maintenance costs are expensed as
incurred.
</FONT>
<P align="left"><FONT size="2"><B><I>Stock-Based Compensation</I></B></FONT>

<P align="left"><FONT size="2">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We have adopted the disclosure-only provisions of SFAS No.&nbsp;123,
<I>&#147;Accounting for Stock-Based Compensation&#148; </I>and apply Accounting Principles Board
Opinion No.&nbsp;25 (APB 25), and related interpretations in accounting for our
stock option plans. Under the provisions of APB 25 and related interpretations,
employee stock-based compensation expense is recognized based on the intrinsic
value of the option on the date of grant.
</FONT>
<P align="left"><FONT size="2">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;At December&nbsp;31, 2002 we had several stock-based employee compensation
plans, which are described more fully in Note 6. All options granted under
these plans had exercise prices equal to the market value of the underlying
common stock on the date of grant and therefore no stock-based employee
compensation cost was recorded in net loss on the grant dates.
</FONT>
<P align="left"><FONT size="2">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The following table illustrates the effect on net loss and net loss per
share if we had applied the fair value recognition of SFAS 123, <I>Accounting for
Stock-Based Compensation</I>, to stock-based employee compensation.

<P align="left"><FONT size="2">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In accordance with Statement of Financial Accounting Standard No.&nbsp;130,
&#147;Reporting Comprehensive Income&#148; (SFAS 130), the Company has reported
comprehensive income, defined as net income (loss)&nbsp;plus other comprehensive
income, in the Statements of Stockholders&#146; Equity. The total of other
accumulated comprehensive income consists of unrealized gains and losses on
marketable securities.
</FONT>
<P align="left"><FONT size="2"><B><I>Per Share Data</I></B></FONT>

<P align="left"><FONT size="2">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Basic EPS is based on the weighted average number of common shares
outstanding. Diluted EPS is based on the weighted average number of common
shares and dilutive potential common shares. Dilutive potential common shares
are calculated under the treasury stock method and consist of unexercised stock
options and warrants.

<P align="left"><FONT size="2"><B><I>Use of Estimates</I></B></FONT>

<P align="left"><FONT size="2">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The preparation of financial statement in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.

<P align="left"><FONT size="2"><B><I>Recent Accounting Pronouncements</I></B></FONT>

<P align="left"><FONT size="2">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In November 2002, the Emerging Issues Task Force (EITF)&nbsp;issued EITF Issue
No.&nbsp;00-21, &#147;Revenue Arrangements with Multiple Deliverables&#148;, which provides
guidance on the timing and method of revenue recognition for sales arrangements
that include the delivery of more than one product or service. EITF 00-21 is
effective prospectively for arrangements entered into in fiscal periods
beginning after June&nbsp;15, 2003. The Company does not expect that the adoption
of EITF 00-21 will have a significant impact on its financial statements.
</FONT>
<P align="left"><FONT size="2">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In June 2002, the Financial Accounting Standards Board (FASB)&nbsp;issued
Statement No.&nbsp;146, &#147;Accounting for Costs Associated with Exit or Disposal
Activities&#148;. The standard addresses financial accounting and reporting for
costs associated with exit or disposal activities and nullifies Emerging Issues
Task Force (EITF)&nbsp;Issue No.&nbsp;94-3, &#147;Liability Recognition for Certain Employee
Termination Benefits and Other Costs to Exit an Activity (including Certain
Costs Incurred in a Restructuring).&#148; Statement No.&nbsp;146 states that a liability
for a cost associated with an exit or disposal activity shall be recognized and
measured initially at its fair value in the period in which the liability is
incurred, except for a liability for one-time termination benefits that are
incurred over a period of time. The standard will apply to the Company
effective for exit or disposal activities initiated after December&nbsp;31, 2002.
The Company does not believe there will be a material effect from the adoption
of this new standard.
</FONT>
<P align="left"><FONT size="2">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On December&nbsp;31, 2002, FASB issued SFAS No.&nbsp;148, Accounting for Stock-Based
Compensation-Transition and Disclosure. SFAS No.&nbsp;148 amends SFAS No.&nbsp;123,
Accounting for Stock-Based Compensation. SFAS No.&nbsp;148 requires accounting
policy note disclosures to provide the method of stock option accounting for
each year presented in the financial statements and, for each year until all
years presented in the financial statements recognize the fair value of
stock-based compensation. Also, SFAS No.&nbsp;148 provides two additional
transition methods that eliminate the ramp-up effect resulting from applying
the expense recognition provisions of SFAS No.&nbsp;123. The transition provisions
and annual statement disclosure requirements of SFAS No.&nbsp;148 are effective for
fiscal years ending after December&nbsp;15, 2002. The interim statement disclosure
requirements are effective for the first interim statement that includes
financial information after December&nbsp;15, 2002. The Company does not believe
there will be a material financial effect from the adoption of this new
standard unless it were to make a change in its accounting policy and account
for stock option grants as compensation expense.
</FONT>
<P align="left"><FONT size="2">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In November 2002, the FASB issued FASB Interpretation No.&nbsp;45 (&#147;FIN 45&#148;),
&#147;Guarantor&#146;s Accounting and Disclosure Requirements for Guarantees, Including
Indirect Guarantees of Indebtedness of Others, an interpretation of FASB
Statements No.&nbsp;5, 57 and 107 and Rescission of FASB Interpretation No.&nbsp;34.&#148;
FIN 45 clarifies the requirements of SFAS No.&nbsp;5, &#147;Accounting for
Contingencies,&#148; relating to the guarantor&#146;s accounting for, and disclosure of,
the issuance of certain types of guarantees. The disclosure provisions of FIN
45 are effective for financial statements of periods that end after December
15, 2002. However, the provisions for initial recognition and measurement are
effective on a prospective basis for guarantees that are issued or modified
after December&nbsp;31, 2002. The Company is still assessing the potential impact
on its results from operations from the adoption of FIN 45.
</FONT>
<P align="left"><FONT size="2">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In January 2003, the FASB issued FASB Interpretation No.&nbsp;46 (&#147;FIN 46&#148;),
&#147;Consolidation of Variable Interest Entities.&#148; FIN 46 clarifies the
application of Accounting Research Bulletin No.&nbsp;51, &#147;Consolidated Financial
Statements,&#148; to certain entities in which equity investors do not have the
characteristics of a controlling financial interest or do not have sufficient
equity at risk for the entity to finance its activities without additional
subordinated financial support from other parties. FIN 46 applies immediately
to variable interest entities created after January&nbsp;31, 2003, and to variable
interest entities in which an enterprise obtains an interest after that date.
It applies in the first fiscal year or interim period beginning after June&nbsp;15,
2003, to variable interest entities in which an enterprise holds a variable
interest that it acquired before February&nbsp;1, 2003. FIN 46 applies to public
enterprises as of the beginning of the applicable interim or annual period.
The Company does not believe there will be a material effect upon its financial
condition or results of operations from the adoption of the provisions of FIN
46.

related to a change in net operating loss shielding allowed for alternative
minimum taxes that were originally paid in 1996, 1997 and 1999. This change in
regulations occurred in early 2002 and the Company subsequently filed amended
returns and received the refunds in late 2002. In 2001, the Company paid
$200,000 for international withholding taxes on license fees received during
the year. In 2000, the Company received a refund of $176,939 for international
withholding taxes that were originally paid in 1995. Due to the uncertainty of
receipt of this refund, a valuation allowance had previously been provided for
this refund receivable.

increased $4.2&nbsp;million and $464,000 for the years ended December&nbsp;31, 2002 and
2001, respectively. The increase in the deferred tax assets in 2002 is
primarily the result of increasing net operating loss carryforwards.
</FONT>
<P align="left"><FONT size="2">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;At December&nbsp;31, 2002, the Company has federal net operating loss
carryforwards of approximately $40.1&nbsp;million for income tax reporting purposes
and research and development and AMT tax credit carryforwards of approximately
$1.8&nbsp;million. The federal operating loss carryforwards and research and
development credits begin to expire in 2006. To the extent that net operating
loss carryforwards, when realized, relate to stock option deductions of
approximately $182,000, the resulting benefit will be credited to stockholders&#146;
equity.
</FONT>
<P align="left"><FONT size="2">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The initial public offering of common stock by the Company in 1995 caused an
ownership change pursuant to applicable regulations in effect under the
Internal Revenue Code of 1986. Therefore, the Company&#146;s use of losses incurred
through the date of ownership change will be limited during the carryforward
period and may result in the expiration of net operating loss carryforwards
before utilization.

are reserved for future issuance pursuant to stock option grants or other
issuances. Under the 2000 Stock Incentive Plan, an incremental number of
shares equal to four percent of the Company&#146;s common stock outstanding as of
December&nbsp;31 of each year commencing December&nbsp;31, 2000 are made available for

Employee stock options vest over a period of time determined by the Board of
Directors, generally four years, and director stock options are generally fully
vested on the date of grant. Stock options generally are granted at the fair
market value on the date of grant and expire ten years from the date of grant.

<P align="left"><FONT size="2">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Proforma information regarding net loss per share required by SFAS 123 and
disclosed in Note 1 has been determined as if we accounted for our employee
options under the fair value method of SFAS 123. The fair value of each option
is estimated using the Black-Scholes option pricing model. The assumptions
used in this model include (1)&nbsp;the stock price at grant date, (2)&nbsp;the exercise
price, (3)&nbsp;an estimated option life of four years, (4)&nbsp;no expected dividends
for each year presented, (5)&nbsp;stock price volatility factor of 1.154, 1.175, and
1.14 in 2002, 2001 and 2000, respectively, and (6)&nbsp;a risk-free interest rate of
3.82%, 4.56% and 6.35% in 2002, 2001 and 2000, respectively. The weighted
average fair value per share of options granted during 2002, 2001 and 2000 was
$2.06, $5.23 and $2.38, respectively.

<P align="left"><FONT size="2">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Company has a 401(k) plan for all employees under which it provides a
specified percentage match on employee contributions. Starting in 2001, this
match was made in shares of the Company&#146;s common stock. Shares issued as
matching contributions under the plan were 18,240 and 14,478 in 2002 and 2001,
respectively. At December&nbsp;31, 2002, a total of 67,282 shares remain available
for future issuances as matching contributions under the plan.

<P align="left"><FONT size="2"><B><I>Stockholder Receivable</I></B></FONT>

<P align="left"><FONT size="2">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In October 2000, the Company entered into stock purchase agreements with
certain officers whereby the officers purchased 400,000 shares of common stock
at the fair market value of the stock on the date of purchase in exchange for
full-recourse promissory notes totaling $350,000, with interest due annually at
the rate of 6.09%. The promissory notes and accrued interest were repaid during
2001.

<P align="left"><FONT size="2"><B><I>Shareholder Rights Plan</I></B></FONT>

<P align="left"><FONT size="2">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Company has adopted a Shareholder Rights Plan (&#147;Plan&#148;) which was
amended in July 2002. Under the Plan, as amended, the Company&#146;s Board of
Directors declared a dividend of one Preferred Stock Purchase Right (&#147;Right&#148;)
for each outstanding common share of the Company. The Rights have an exercise
price of $140 per Right and provide the holders with the right to purchase, in
the event a person or group acquires 15% or more of the Company&#146;s common stock,
additional shares of the Company&#146;s common stock having a market value equal to
two times the exercise price of the Right. The Rights expire in 2006.

each year commencing December&nbsp;31, 2000 are made available for issuance

with 66,384 available for issuance as of December&nbsp;31, 2002. Options to
purchase 542,208 shares of common stock under the 1999 Plan were

of $4.44. Stock options issued under the 1999 Plan are generally granted
with an exercise price equal to fair market value on the date of grant,
but in no event may be less than 85% of the then fair market value.
Options under the 1999 Plan have various vesting schedules and expire ten
years from the date of grant. The 1999 Plan also authorizes the issuance
of restricted stock, although no restricted stock grants have been issued
under the 1999 Plan. Shares underlying unexercised options that expire or
are terminated become available again for future grants.</FONT></TD>

upon the evaluation, our Chief Executive Officer and Chief Financial Officer
concluded that our disclosure controls and procedures are effective in timely
