ISTA Pharmaceuticals, Inc.

Notes to Unaudited Condensed Consolidated Financial Statements

June 30, 2004



1. The Company



ISTA Pharmaceuticals, Inc. (ISTA or the Company) is a specialty pharmaceutical company focused on the commercialization and
development of unique and uniquely improved products for serious conditions of the eye. ISTA is currently preparing to launch its first two products approved by the U.S Food and Drug Administration, or FDA, which are Vitrase®, for use as a spreading agent, and Istalol, for the treatment of glaucoma. In addition, ISTA has two New Drug Applications, or NDAs, on file with the FDA, which are Vitrase,
for the treatment of vitreous hemorrhage and Xibrom, for the treatment of ocular
inflammation following cataract surgery.



As of June 30, 2004,
ISTA had approximately $35.5 million in cash and cash equivalents and short-term investments. ISTA incurred a net loss of $13.6 million for the six months ended June 30, 2004 and had an accumulated deficit of $161.2 million at June 30, 2004. The
ability of ISTA to continue as a going concern is dependent upon its ability to obtain additional capital and achieve profitable operations. ISTAs ability to transition from the development stage and ultimately, to attain profitable
operations, is dependent upon obtaining sufficient working capital to complete the successful development of its products, approval by the FDA of its products, achieving market acceptance of such approved products and achievement of sufficient
levels of revenue to support ISTAs cost structure and growth.



ISTA believes that its current cash and cash equivalents and short-term investments will be sufficient to finance its anticipated capital and operating requirements for at least the next twelve months. If ISTA engages
in acquisitions of companies, products, or technology in order to execute its business strategy, ISTA may need to raise additional capital. ISTA may be required to raise additional capital in the future through collaborative agreements, private
investment in public equity, or PIPE, financings, and various other public or private equity or debt financings. If ISTA is required to raise additional capital in the future, there can be no assurance that the additional financing will be available
on favorable terms, or at all.



The unaudited condensed
consolidated financial statements contained in this Form 10-Q do not include any adjustments to the specific amounts and classifications of assets and liabilities that might be necessary should ISTA be unable to continue as a going concern.

2. Basis of Presentation



General



The unaudited condensed consolidated financial statements included herein have been prepared by the Company pursuant to the rules and regulations of the
U.S. Securities and Exchange Commission, or SEC. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States have been condensed or
omitted pursuant to such rules and regulations. In managements opinion, the accompanying financial statements have been prepared on a basis consistent with the audited financial statements and contain adjustments, consisting of only normal,
recurring accruals, necessary to present fairly the Companys financial position and results of operations. Interim financial results are not necessarily indicative of results anticipated for the full year.



The preparation of financial statements in conformity with accounting
principles generally accepted in the United States 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.



For further information, refer to the consolidated financial
statements and footnotes thereto included in the Companys annual report on Form 10-K, for the year ended December 31, 2003.



3. Revenue Recognition



The Company recognizes revenue consistent with the provisions of SEC Staff Accounting Bulletin No. 101, Revenue Recognition, which sets forth
guidelines in the timing of revenue recognition based upon factors such as passage of title, installation, payments and customer acceptance. Amounts received for upfront product and technology license fees under multiple-element arrangements are
deferred and recognized ratably over the period of such services or performance if such arrangements require on-going services or performance. Non-refundable amounts received for milestone payments are recognized upon (i) the achievement of
specified milestones when the Company has earned the milestone payment or, (ii) the milestone payment is substantive in nature and the achievement of the milestone was not reasonably assured at the inception of the agreement. The Company defers
payments for milestone events, which are reasonably assured and recognizes them ratably over the minimum remaining period of the Companys performance obligations. Payments for milestones, which are not reasonably assured are treated as the
culmination of a separate earnings process and are recognized as revenue when the milestones are achieved. Royalty revenue will be recognized upon sale of the related products, provided the royalty amounts are fixed and determinable and collection
of the related receivable is probable. Any amounts received prior to satisfying our revenue recognition criteria will be recorded as deferred revenue in the accompanying balance sheets.



In December 2001, the Company began a collaboration with Otsuka Pharmaceutical Co., Ltd. under which Otsuka will be
responsible for all clinical development, regulatory approvals, sales and marketing activities for Vitrase®, for ophthalmic uses in the posterior segment of the eye, in Japan. The Companys principal sources of revenue from this collaboration and the commercialization of Vitrase®will be the license fee received in December 2001, which is being amortized over the Companys continuing involvement with
Otsuka, milestone payments and product sales received from Otsuka. To date, the Company has not earned this milestone payment from Otsuka and it cannot guarantee that it will receive this milestone payment in the future. Under the terms of the
collaboration, the Company is responsible for the manufacture of Vitrase®and supplying
all of Otsukas requirements for Vitrase®.

4. Inventory



Inventory at June 30, 2004 consisted of $90,000 of raw materials and $468,000 of work-in-process. The Company had no inventory at June 30, 2003. We
obtained FDA approval for Vitrase in May 2004. Inventory relates to Vitrase, 6,200 USP units multi-purpose vial, for use as a spreading agent to facilitate the absorption and dispersion of other injected drugs.



5. Comprehensive Income (Loss)



Statement of Financial Accounting Standard, or SFAS, No. 130,
Reporting Comprehensive Income, requires reporting and displaying comprehensive income (loss) and its components, which, for ISTA, includes net loss and unrealized gains and losses on investments and foreign currency translation gains
and losses. Total comprehensive loss for the six-month period ended June 30, 2004 and 2003 was $13,608,000 and $11,358,000, respectively. In accordance with SFAS No. 130, the accumulated balance of unrealized gains (losses) on investments and the
accumulated balance of foreign currency translation adjustments are disclosed as separate components of stockholders equity.



6. Stock-Based Compensation



As permitted by SFAS No. 123, Accounting for Stock-Based Compensation, the Company has elected to follow Accounting Principals Board, or APB,
Opinion No. 25, Accounting for Stock Issued to Employees, and related interpretations in accounting for stock-based employee compensation. Under APB 25, if the exercise price of the Companys employee and director stock options
equals or exceeds the estimated fair value of the underlying stock on the date of grant, no compensation expense is recognized.



When the exercise price of the employee or director stock options is less then the estimated fair value of the underlying stock on the grant date, the
Company records deferred compensation for the difference and amortizes this amount to expense in accordance with Financial Accounting Standards Board, or FASB, Interpretation No. 28, Accounting for Stock Appreciation Rights and Other Variable
Stock Options or Award Plans, over the vesting period of the options.



Options or stock awards issued to non-employees are recorded at their fair value as determined in accordance with SFAS No. 123 and Emerging Issues Task Force, or EITF, No. 96-18, Accounting for Equity
Instruments That Are Issued to Other Than Employees for Acquiring or in Conjunction With Selling Goods or Services, and recognized over the related service period. Deferred charges for options granted to non-employees are periodically
re-measured as the options vest.



As required under SFAS No.
123, Accounting for Stock-Based Compensation, and SFAS No. 148, Accounting for Stock-Based Compensation Transition and Disclosure, the pro forma effects of stock-based compensation on net loss have been estimated at the date
of grant using the Black-Scholes option-pricing model. The Black-Scholes option valuation model was developed for use in estimating the fair value of traded options that have no vesting restrictions and are fully transferable. In addition, option
valuation models require the input of highly subjective assumptions including the expected stock price volatility. Because the Companys employee stock options have characteristics significantly different from those of traded options, and
because changes in the subjective input assumptions can materially affect the fair value estimate, in managements opinion, the existing models do not necessarily provide a reliable single measure of the fair value of its employee stock
options.



In December 2002, the FASB issued SFAS No. 148,
Accounting for Stock-Based CompensationTransition and Disclosure. SFAS No. 148 is an amendment to SFAS No. 123 providing alternative methods of transition for a voluntary change to the fair value based method of accounting for
stock-based employee compensation and also provides additional disclosures about the method of accounting for stock-based employee compensation. Amendments are effective for financial statements for the Company beginning January 1, 2003. The Company
has currently chosen to not adopt the voluntary change to the fair value based method of accounting for stock-based employee compensation. If the Company should choose to adopt such a method, its implementation pursuant to SFAS No. 148 could have a
material effect on the Companys consolidated financial position and results of operations.



The fair value of these options was estimated at the date of grant using the minimum value pricing model for grants prior to the initial public offering
and the Black Scholes method for grants after the initial public offering with the following weighted average assumptions: risk-free interest rate of 3.0%, zero dividend yield, volatility of 73%; and a weighted-average life of the option of four
years.

For purposes of adjusted pro forma disclosures, the estimated fair value of the options is amortized to
expense over the options vesting period. The effect of applying SFAS No. 123 for purposes of providing pro forma disclosures is not likely to be representative of the effects on the Companys operating results for future years because
changes in the subjective input assumptions can materially affect future value estimates. Pro forma information is as follows:

7. Net Loss Per Share



In accordance with SFAS No. 128, Earnings Per
Share, and SEC Staff Accounting Bulletin, or SAB, No. 98, basic net loss per common share is computed by dividing the net loss for the period by the weighted average number of common shares outstanding during the period. Under SFAS No. 128,
diluted net income (loss) per share is computed by dividing the net income (loss) for the period by the weighted average number of common and common equivalent shares, such as stock options, outstanding during the period. Such common equivalent
shares have not been included in the Companys computation of net loss per share as their effect would be anti-dilutive.



Under the provisions of SAB No. 98, common shares issued for nominal consideration, if any, would be included in the per share calculations as if they
were outstanding for all periods presented. No common shares have been issued for nominal consideration.



8. Commitments and Contingencies



The Company is subject to routine claims and litigation incidental to its business. In the opinion of management, the resolution of such claims is not expected to have a material adverse effect on the operating
results or financial position of the Company.



Visionex



Visionex was established in 1997, under the laws of
Singapore, to engage in clinical, regulatory and marketing activities. During 1997, Visionex obtained from the Company the exclusive rights to register, import, market, sell and distribute Vitrase®and a product called Keraform®in East Asian markets, excluding Japan and Korea, for which Visionex paid the Company $5.0 million. Prior to the Companys
acquisition of Visionex (discussed below), investors who owned 66% of ISTA shares controlled 100% of Visionex shares.



On March 8, 2000, the Company acquired Visionex by entering into an agreement with Visionex shareholders whereby the Company issued 3,319,363 shares of
its Series C preferred stock, convertible into 245,879 shares of its common stock, to acquire all of the outstanding capital stock of Visionex. The Company assigned a fair value of $11.70 per share to the 3,319,363 shares of Series C preferred stock
issued to effect the acquisition, at which time the Company recorded a deemed dividend of $19.2 million to recognize the excess of the value of the shares issued over the net assets acquired.



Under Singapore tax law, Visionex was subject to a 15% withholding tax on a
$5.0 million license that it paid to the Company in connection with a license to market, sell and distribute Vitrase®and its other corneaplasty products in certain countries in Southeast Asia. This withholding tax was waived by the Economic Development Board, or EDB, of Singapore subject to various conditions,
including a commitment that Visionex would implement a proposed project to expand its business activities in Singapore to the benefit of the local economy. The Company substantially wound down Visionex operations in July 2002, and the proposed
project was never implemented. Based upon a letter the Company received from the EDB and the Companys assessment of its obligations with the EDB, management does not believe that the Company will be required to pay any withholding tax or
related obligations in connection with the license fee. However, if the Company is required to pay this withholding tax, the Company does not believe such payment would have a material adverse effect on the Companys business.

9. Recent Accounting Pronouncements



In December 2002, the FASB issued SFAS No. 148, Accounting for Stock-Based Compensation  Transition and
Disclosure. SFAS No. 148 is an amendment to SFAS No. 123 providing alternative methods of transition for a voluntary change to the fair value based method of accounting for stock-based employee compensation and also provides additional
disclosures about the method of accounting for stock-based employee compensation. Amendments are effective for financial statements for the Company beginning January 1, 2003. The Company has currently chosen to not adopt the voluntary change to the
fair value based method of accounting for stock-based employee compensation. If the Company should choose to adopt such a method, its implementation pursuant to SFAS No. 148 could have a material effect on the Companys consolidated financial
position and results of operations.

Overview



We are a
specialty pharmaceutical company focused on the commercialization and development of unique and uniquely improved products for serious conditions of the eye. We are currently preparing to launch our first two products approved by the U.S Food and
Drug Administration, or FDA, which are Vitrase®, for use as a spreading agent, and
Istalol, for the treatment of glaucoma. In addition, we have two New Drug Applications,
or NDAs, on file with the FDA, which are Vitrase, for the treatment of vitreous hemorrhage and Xibrom, for the treatment of ocular inflammation following cataract surgery.



We are building our commercial capabilities, including a targeted salesforce, to distribute and market our currently approved products. We estimate that approximately 10,000 ophthalmologists write the majority of the
prescriptions for serious conditions of the eye, and we believe that a targeted salesforce of 50 to 100 representatives can successfully reach this physician population. We have hired four regional sales managers, and have entered into a multi-year
service agreement with Ventiv Health, Inc. under which they will provide us with a dedicated nationwide specialty salesforce, which will promote our products exclusively. Under the terms of our agreement, Ventiv Health will provide full-time sales
representatives selected by and reporting to our senior sales and marketing management team. Ventiv Health has granted us the right to hire these sales representatives for a nominal fee. We intend to leverage our commercial capabilities for our
other late-stage product candidates and additional products we may develop or acquire in the future.



We believe that the prescription market in the United States for ophthalmic pharmaceutical products represents a significant and growing market. According
to industry sources, this market has annual sales of approximately $2.5 billion and a historic growth rate of over 12% per year.

Our Products and Pipeline



Istalol



Istalol is a once-a-day, eye drop solution of timolol, a beta-blocking agent for the treatment of glaucoma. We received FDA approval of Istalol in June 2004 and plan commercial launch of Istalol
during the third quarter of 2004. Beta-blockers are a large group of approved medications that block specific receptors in the central nervous system and are used in the treatment of a number of diseases including glaucoma. Timolol maleate, which is
currently available from several manufacturers, is the leading beta-blocker to treat glaucoma in the United States. In clinical trials, Istalol, given once-a-day, has shown efficacy and safety comparable to a timolol maleate solution, given
twice-a-day. In addition to this dosing advantage, Istalol is formulated as an eye drop solution versus commonly available once-a-day gel formulations of timolol, which have been known to cause blurring of patients vision. We acquired U.S.
marketing rights for Istalol under a license agreement with Senju Pharmaceuticals Co., Ltd.



According to data compiled by NDC Health, we estimate the U.S. glaucoma pharmaceutical market is approximately $1.1 billion annually. Of this market, the ophthalmic beta-blocker segment represents approximately $170
million per year, primarily at generic prices, with over 4.4 million prescriptions written annually.



Vitrase



Vitrase® is a highly purified, proprietary formulation of ovine
hyaluronidase. In May 2004, the FDA approved our NDA for Vitrase, in a 6,200 USP units multi-purpose vial, for use as a spreading agent to facilitate the absorption and dispersion of other injected drugs. During the third quarter of 2004, we intend
to file a supplemental NDA for Vitrase for use as a spreading agent at a lower concentration of 150 USP units/mL. We believe the 150 USP units/mL product will help facilitate utilization and aid in obtaining appropriate third party reimbursement.



We are also developing Vitrase for the treatment of vitreous
hemorrhage and diabetic retinopathy. In October 2002, we submitted a NDA for Vitrase for the treatment of vitreous hemorrhage by injection into the posterior region of the eye. On April 3, 2003, the FDA issued an approvable letter citing issues
primarily related to the sufficiency of the efficacy data submitted with this NDA. The FDA requested additional analysis of the existing data and an additional confirmatory clinical study based upon that analysis. We have submitted information to
the FDA in response to its comments contained in the approvable letter. We believe that all non-clinical issues have been resolved with the FDA, and we are continuing to assess and discuss with the FDA the clinical issues raised in the approvable
letter. Based upon these discussions, we will determine the next appropriate steps in the approval process of Vitrase for the treatment of vitreous hemorrhage. The continued development of Vitrase for the treatment of diabetic retinopathy will be
dependent upon the FDAs evaluation of the Vitrase NDA for the treatment of vitreous hemorrhage, among other factors.



Based on published reports, we believe the potential annual market opportunity for Vitrase as a spreading agent consists of the 3,000,000 ophthalmic
surgeries performed in the United States each year, of which 2,600,000 are cataract surgeries. In addition, based on data compiled for us by The Wilkerson Group, we believe that the potential annual market opportunity in the United States for
Vitrase for the treatment of vitreous hemorrhage is approximately 225,000 cases. We intend to seek a higher reimbursement price for Vitrase for the treatment of vitreous hemorrhage, and therefore we believe that this market represents a larger
market opportunity than for use as a spreading agent.



Xibrom



Xibrom is a topical non-steroidal anti-inflammatory formulation of bromfenac for the
treatment of ocular inflammation, eye pain and photophobia following cataract surgery. Senju launched this product in Japan in 2000. We acquired U.S. marketing rights for Xibrom under a license agreement with Senju. We completed two pivotal Phase
III clinical studies of Xibrom in the United States and submitted a NDA in May 2004. In these studies, a statistically significant proportion of patients treated with Xibrom achieved treatment success, defined as the complete absence of ocular
inflammation, compared to those patients who received placebo.



Based on data compiled by NDC Health, we estimate that over 5.4 million prescriptions are written annually for topical ophthalmic anti-inflammatory agents in the United States.

Caprogel



Caprogel®, a topical gel formulation of aminocaproic acid for treatment of hyphema, has received an orphan drug designation from the FDA. In May 2002, we acquired worldwide marketing rights for Caprogel under a license agreement with the
Eastern Virginia Medical School. We are currently conducting feasibility studies for Caprogels reformulation and commercialization. Once completed, and if these studies yield promising results, we intend to pursue the remaining Phase III
clinical development.



Based on data compiled for us by
Milliman U.S.A., we believe that hyphema affects an estimated 50,000 patients per year in the United States.



Company Information



We
incorporated in California in February 1992 as Advanced Corneal Systems, Inc. In March 2000, we changed our name to ISTA Pharmaceuticals, Inc., and we reincorporated in Delaware in August 2000. Our corporate headquarters are located at 15279 Alton
Parkway, Suite 100, Irvine, CA 92618, and our telephone number is (949) 788-6000.



We have incurred losses since inception and had an accumulated deficit of $161.2 million through June 30, 2004. Our losses have resulted primarily from research and development activities, including clinical trials,
general and administrative expenses and a deemed dividend to our preferred shareholders. We expect to continue to incur operating losses for the foreseeable future as we continue to conduct research, development and clinical testing activities, to
seek regulatory approval for our product candidates, and to prepare to launch our approved products.



Results of Operations



The following discussion of our results of operations generally reflects our continuing transition to a commercial-stage company with a primary focus on ophthalmology.



Three Months Ended June 30, 2004 and 2003



Revenue.Revenue of $70,000 for the three months ended June 30, 2004 and $70,000 for the three months ended June 30, 2003 reflects the
amortization for the period of deferred revenue recorded in December 2001 for the license fee payment made by Otsuka Pharmaceutical Co. Ltd. for commercialization rights to Vitrase®in Japan for ophthalmic uses in the posterior regions of the eye.



Research and development expenses.Research and development expenses for the three months ended June 30, 2004 were
$5.6 million compared to $3.9 million for the three months ended June 30, 2003. Our research and development expenses have consisted primarily of costs associated with the clinical trials of our product candidates, compensation and other expenses
for research and development personnel, costs for consultants and contract research organizations and costs related to the development of commercial manufacturing capabilities for Vitrase®, Istalol and Xibrom. During the three months ended June 30, 2004, the Company incurred two non-recurring expenses. First, a $500,000 milestone payment was recorded upon
FDA approval of Istalol and is payable to Senju Pharmaceuticals, Ltd., during the third quarter of 2004. Second, a one-time license fee expense of $1.3 million, consisting of $1.1 million in cash and debt and $0.2 million in fixed assets was
recorded upon the Company entering into a technology license agreement and an amended and and restated supply agreement with Biozyme Laboratories, Ltd., our supplier of hyaluronidase for Vitrase. The debt is payable to Biozyme in installments over
three years. Exclusive of these two non-recurring expenses, research and development expenses decreased by $100,000 as a result of the Company obtaining FDA approval of Vitrase and Istalol, which resulted in the capitalization of various amounts
into commercial inventory.



Selling, general and
administrative expenses.Selling, general and administrative expenses were $3.0 million for the three months ended June 30, 2004 compared to $2.3 million for the three months ended June 30, 2003. Selling, general and administrative
expenses increased by $700,000 due to increased consultant costs and marketing activities associated with the Companys preparations for the anticipated commercial product launch of its approved products.



Interest income.Interest income was $131,000 for the three months
ended June 30, 2004 compared to $94,000 for the three months ended June 30, 2003. The increase in interest income was primarily attributable to higher cash balances for the three months ended June 30, 2004 compared to the three months ended June 30,
2003 due to the financing that was completed during the fourth quarter of 2003.

##### Table of Contents

Interest expense. There was no interest expense recorded for the three months ended June 30, 2004
compared to $1,000 for the three months ended June 30, 2003. Interest expense for the three month period ended June 30, 2004 was attributable to the interest paid on the financing of our directors and officers insurance premiums.



Six Months Ended June 30, 2004 and 2003



Revenue.Revenue of $139,000 and $139,000 for the six months ended
June 30, 2004 and the six months ended June 30, 2003 reflects the amortization for the period of deferred revenue recorded in December 2001 for the license fee payment made by Otsuka in connection with the license for Vitrase® in Japan.



Research and development expenses.Research and development expenses
for the six months ended June 30, 2004 were $8.6 million compared to $7.4 million for the six months ended June 30, 2003. Our research and development expenses have consisted primarily of costs associated with the clinical trials of our product
candidates, compensation and other expenses for research and development personnel, costs for consultants and contract research organizations and costs related to the development of commercial manufacturing capabilities for Vitrase®, Istalol and Xibrom. During the six months ended June 30, 2004, the Company incurred two non-recurring expenses. First, a $500,000
milestone payment was recorded upon FDA approval of Istalol and is payable to Senju Pharmaceuticals, Ltd., during the third quarter of 2004. Second, a one-time license fee expense of $1.3 million, consisting of $1.1 million in cash and debt and $0.2
million in fixed assets was recorded upon the Company entering into a technology license agreement and amended and and restated supply agreement with Biozyme Laboratories, Ltd., our supplier of hyaluronidase for Vitrase. The debt is payable to
Biozyme in installments over three years. Exclusive of these two non-recurring expenses, research and development expenses decreased by $600,000 as a result of the Company obtaining FDA approval of Vitrase and Istalol, which resulted in the
capitalization of various amounts into commercial inventory. We anticipate that our operating expenses will substantially increase from historical levels as we expand our commercial infrastructure to launch our approved products.



Selling, general and administrative expenses.General and
administrative expenses were $5.4 million for the six months ended June 30, 2004 compared to $4.4 million for the six months ended June 30, 2003. The increase in selling, general and administrative expenses is primarily due to increased consultant
costs and marketing activities associated with in the Companys preparations for the anticipated commercial product launch of its approved products.



Interest income.Interest income was $280,000 for the six months ended June 30, 2004 compared to $209,000 for the six months ended June 30, 2003.
The increase in interest income was attributable to higher cash balances during the first six months of 2004 compared to the first six months of 2003.



Interest expense.Interest expense was $2,000 for the six months ended June 30, 2004 compared to $6,000 for the six months ended June 30, 2003. The
interest expense was primarily attributable to the financing of our directors and officers insurance premiums during both the six months ended June 30, 2004 and 2003.



Liquidity and Capital Resources



As of June 30, 2004, we had approximately $35.5 million in cash and equivalents and short-term investments and working capital of $31.3 million.



We have financed our operations since inception primarily
through private equity sales and the sale of our common stock in our initial and follow-on public offerings. We received net proceeds of $10.0 million from the private sale of preferred stock in March 2000, $31.7 million from our initial public
offering in August 2000, $4.0 million from the private sale of common stock in December 2001, $5.0 million from a license fee payment in December 2001, $4.0 million from the issuance of promissory notes in September 2002, $37.3 million from our PIPE
transaction in November 2002 and $35.7 million from our follow-on public offering in November 2003. The PIPE transaction in November 2002 consisted of a private placement of 10,526,306 shares of our common stock for the aggregate purchase price of
approximately $40.0 million, or $3.80 per share, and warrants to purchase up to 1,578,946 shares of our common stock for an exercise price of $3.80 per share. The follow-on public offering in November 2003 consisted of the sale of 4,000,000 shares
of our common stock for the aggregate purchase price of $38.0 million, or $9.50 per share. On April 23, 2004, we filed a universal shelf registration statement on Form S-3 with the SEC providing for the offering from time to time of up to
$75,000,000 of our securities, which may consist of common stock, preferred stock, warrants, or debt securities. The shelf registration statement also includes up to 3,600,000 shares of our common stock to be offered by certain selling stockholders.



For the six months ended June 30, 2004, we used $12.8 million
of cash for operations principally as a result of the net loss of $13.6 million partially offset by non-cash compensation expense of $205,000. We used approximately $10.6 million of cash for operations in the six months ended June 30, 2003.

##### Table of Contents

For the six months ended June 30, 2004, we received $6.7 million of cash from investing activities,
primarily due to the maturities of our short-term investment securities. For the six months ended June 30, 2003, we used $6.6 million of cash from investing activities, primarily due to the purchase of our short-term investment securities.



For the six months ended June 30, 2004, we received $41,000
from financing activities, primarily from the exercise of stock options and the issuance of common stock under our Employee Stock Purchase Plan. For the six months ended June 30, 2003, we received $84,000 from financing activities, primarily from
the exercise of stock options.



We may be required to raise
additional capital in the future through collaborative agreements, PIPE related financings, and various other public or private equity or debt financings. If we are required to raise additional capital in the future, there can be no assurance that
the additional financing will be available on favorable terms, or at all.



We continually evaluate new opportunities for late-stage or currently marketed complementary product candidates and, if and when appropriate, intend to pursue such opportunities through the acquisitions of companies,
products, or technology and our own research and development activities. Our ability to execute on such opportunities in some circumstances will be dependent, in part, upon our ability to raise additional capital on commercially reasonable terms.
There can be no assurance that funds from these sources will be available when needed or, if available, will be on terms favorable to us or to our stockholders. If additional funds are raised by issuing equity securities, the percentage ownership of
our stockholders will be reduced, stockholders may experience additional dilution or such equity securities may provide for rights, preferences or privileges senior to those of the holders of our common stock.



Our actual future capital requirements will depend on many factors, including
the following:



| |  | activities and payments in connection with obtaining licenses for or acquisition of products including, but not limited to, reacquiring rights in our existing products and
technologies;
| | - | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  | sales and marketing activities related to our approved products and product candidates;

| | - | --------------------------------------------------------------



| |  | our ability to establish and maintain collaborative relationships;
| | - | ------------------------------------------------------------------



| |  | competitive, technological, market and other developments; and
| | - | --------------------------------------------------------------



| |  | the success of the commercialization of our products.
| | - | -----------------------------------------------------

Factors that May Affect Results of Operations and Financial Condition.



Risks Related to Our Business



If we do not receive and maintain regulatory approvals for our product candidates, we, or
our marketing partners, will not be able to commercialize our products, which would substantially impair our ability to generate revenues and materially harm our business and financial condition.



Only two of our product candidates have received regulatory approval from
the FDA. In May 2004, the FDA approved our NDA for Vitrase for use as a spreading agent. In June 2004, we received FDA approval of the NDA for Istalol for the treatment of glaucoma. Approval from the FDA is necessary to manufacture and market
pharmaceutical products in the United States. Many other countries including major European countries and Japan have similar requirements.



The regulatory approval process is extensive, time-consuming and costly, and there is no guarantee that the FDA will approve additional NDAs for our
product candidates, or that the timing of any such approval will be appropriate for our product launch schedule and other business priorities, which are subject to change. We have submitted two NDAs which are currently pending before the FDA, one
for Vitrase for the treatment of vitreous hemorrhage and one for Xibrom for the treatment of ocular inflammation, eye pain and photophobia.



Although we have received an approvable letter from the FDA with respect to our NDA for Vitrase for the treatment of vitreous hemorrhage, the FDA has
requested additional analysis of the existing data and an additional confirmatory clinical study based upon that analysis. There can be no assurances that the FDA will approve this NDA for Vitrase, even if we decide to and are successfully able to
undertake the further analysis and clinical testing requested by the FDA.



While we have received FDA approval of Vitrase for use as a spreading agent, we plan to file a supplemental NDA during the third quarter of 2004 for a lower concentration of 150 USP units/mL that we believe is optimal
for this use. There can be no assurances that the FDA will approve this supplemental NDA or that the timing of any such approval will be consistent with our preparation for product launch. Failure to obtain approval of this supplemental NDA could
adversely impact the commercial potential of Vitrase for use as a spreading agent.



Clinical testing of pharmaceutical products is also a long, expensive and uncertain process. Even if initial results of preclinical studies or clinical trial results are positive, we may obtain different results in
later stages of drug development, including failure to show desired safety and efficacy.



The clinical trials of any of our product candidates could be unsuccessful, which would prevent us from obtaining regulatory approval and commercializing the product.



FDA approval can be delayed, limited or not granted for many reasons,
including, among others:



| |  | FDA officials may not find a product candidate safe or effective to merit an approval;
| | - | --------------------------------------------------------------------------------------



| |  | FDA officials may not find that the data from preclinical testing and clinical trials justifies approval, or they may require additional studies that would make it commercially
unattractive to continue pursuit of approval;
| | - | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  | the FDA might not approve the processes or facilities of our contract manufacturers or raw material suppliers or our manufacturing processes or facilities;
| | - | -----------------------------------------------------------------------------------------------------------------------------------------------------------



| |  | the FDA may change its approval policies or adopt new regulations; and
| | - | ----------------------------------------------------------------------



| |  | the FDA may approve a product candidate for indications that are narrow or under conditions that place our product at a competitive disadvantage, which may limit our sales and
marketing activities or otherwise adversely impact the commercial potential of a product.
| | - | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



If the FDA does not approve our product candidates in a timely fashion on commercially viable terms or we terminate development of any of our product
candidates due to difficulties or delays encountered in the regulatory approval process, it will have a material adverse impact on our business and we will be dependent on the development of our other product candidates and/or our ability to
successfully acquire other products and technologies.

In addition, we intend to market certain of our products, and perhaps have certain of our products
manufactured, in foreign countries. The process of obtaining approvals in foreign countries is subject to delay and failure for similar reasons.



Even though we obtained FDA approval of the Vitrase NDA for use as a spreading agent, our ability to commercialize Vitrase for such use is dependent upon the terms of
our collaboration with Allergan.



We have entered into a
collaboration with Allergan, Inc. relating to Vitrase for ophthalmic uses for the posterior region of the eye. We are currently in active discussions with Allergan regarding Vitrase and our collaboration. If we are unable to reach a satisfactory
agreement with Allergan, Allergan has informed us of its position that we need its authorization pursuant to our collaboration to market Vitrase on our own as a spreading agent, which Allergan asserts has not been provided. In addition, Allergan may
be unwilling to pursue the marketing and commercialization of Vitrase for the posterior region of the eye or any final FDA approved labeling that does not meet its satisfaction. Any dispute regarding our rights or Allergans rights under our
collaboration or otherwise would be costly, time-consuming and potentially delay or possibly prevent the launch of any approved Vitrase product.



If our product candidates are approved by the FDA but do not gain market acceptance, our business will suffer because we might not be able to fund future operations.



A number of factors may affect the market acceptance of
our products or any other products we develop or acquire, including, among others:



| |  | the price of our products relative to other therapies for the same or similar treatments;
| | - | -----------------------------------------------------------------------------------------



| |  | the perception by patients, physicians and other members of the health care community of the effectiveness and safety of our products for their prescribed treatments;
| | - | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  | our ability to fund our sales and marketing efforts; and
| | - | --------------------------------------------------------



| |  | the effectiveness of our sales and marketing efforts.
| | - | -----------------------------------------------------



In addition, our ability to market and promote our products will be restricted to the labels approved by the FDA. If the approved labels are restrictive,
our sales and marketing efforts and market acceptance and the commercial potential of our products may be negatively affected. For example, should the market not widely accept Vitrase for usage based on the label of the approved NDA, we may have to
await approval of additional indications in order to reach the full market potential for this drug.



If our products do not gain market acceptance, we may not be able to fund future operations, including the development or acquisition of new product
candidates and/or our sales and marketing efforts for our approved products, which would cause our business to suffer.



If we are unable to sufficiently develop our sales, marketing and distribution capabilities and/or enter into agreements with third parties to perform these functions,
we will not be able to commercialize products.



We
currently are in the process of developing our sales, marketing and distribution capabilities. Although we have begun to expand our capabilities, our current resources in these areas are limited. In order to commercialize any products successfully,
we must continue to develop substantial sales, marketing and distribution capabilities, and/or maintain our arrangements with Ventiv Health or establish other collaborations or other arrangements with third parties to perform these services. We do
not have extensive experience in these areas, and we may not be able to establish adequate in-house sales, marketing and distribution capabilities or engage and effectively manage relationships with third parties to perform any or all of such
services. To the extent that we enter into co-promotion, licensing or other third party arrangements, our product revenues and returns are likely to be lower than if we directly marketed and sold our products, and any revenues we receive will depend
upon the efforts of third parties, whose efforts may not be successful.



If
we fail to properly manage our anticipated growth, our business could suffer.



Rapid growth of our business is likely to place a significant strain on our managerial, operational and financial resources and systems. We have increased our full-time employee count from 42 as of January 1, 2004 to
57 as of June 30, 2004. To execute our anticipated growth successfully, we must attract and retain qualified personnel and manage and train



16

them effectively. We will be dependent on our personnel and third parties to effectively manufacture, market, sell and
distribute our products. We will also depend on our personnel and third parties to successfully develop and acquire new products. Further, our anticipated growth will place additional strain on our suppliers and manufacturers, resulting in increased
need for us to carefully manage these relationships and monitor for quality assurance. Although we cannot assure you that we will, in fact, grow as we expect, if we fail to manage our growth effectively or to develop and expand a successful
commercial infrastructure to support marketing and sales of our products, our business and financial results will be materially harmed.



We have not generated any revenue from product sales to date, we have a history of net losses and negative cash flow, and we may need to raise additional working
capital.



We have not generated any revenue from product
sales to date, and we may never generate revenues from product sales in the future. We have never been profitable, and we might never become profitable. As of June 30, 2004, our accumulated deficit was $161.2 million, including a net loss of
approximately $25.2 million for the year ended December 31, 2003 and a net loss of $13.6 million for the six months ended June 30, 2004. As of June 30, 2004, we had approximately $35.5 million in cash and cash equivalents and short-term investments
and working capital of $31.3 million. We believe our current cash and cash equivalents and short-term investments on hand will be sufficient to finance anticipated capital and operating requirements for at least the next twelve months. We
anticipate, however, that our operating expenses will substantially increase from historical levels as we expand our commercial infrastructure to launch our approved products. If we are unable to generate sufficient product revenues, we may be
required to raise additional capital in the future through collaborative agreements, private investment in public equity financings, and various other public or private equity or debt financings. If we are required to raise additional capital in the
future there can be no assurance that the additional financing will be available on favorable terms, or at all.



We may be unable to execute our strategic plan to transition to a commercial-stage company, which could have a material adverse impact on our business and financial
condition.



Our strategy to transition to a
commercial-stage company will be dependent upon our ability to gain additional regulatory approvals for our product candidates and market acceptance for our approved products, build a commercial infrastructure to support multiple product launches,
conduct business development efforts to further expand our late-stage product pipeline, and pursue opportunistic acquisitions of or licenses for marketed products.



We have limited sales, marketing and distribution capabilities to support the marketing of any products, and we do not have
experience in managing third-party manufacturers of any products in commercial quantities. In addition, if we acquire or obtain licenses for late-stage development products, our ability to successfully commercialize such products will also be
dependent on our ability to successfully complete development of such products, including obtaining the necessary regulatory approvals. For example, we have obtained a license for U.S. marketing rights to Xibrom from Senju, and we have obtained a
license for worldwide rights to Caprogel from the Eastern Virginia Medical School. We are also responsible for the development of both Xibrom and Caprogel.



We may not be able to identify any product acquisition opportunities or be successful in negotiating favorable terms for any such product acquisitions.
Should we be successful in acquiring or licensing any products, we will need to enhance our sales, marketing, distribution and manufacturing capabilities, each of which will require substantial financial and management resources. Our failure to
establish effective sales, marketing, distribution and manufacturing capabilities on a timely basis would adversely affect our ability to commercialize our products, including any acquired products. If we are unable to execute our strategic plan to
transition to a commercial-stage company on a timely basis, our ability to generate revenues would be substantially impaired which would materially harm our business and financial condition.



If we have problems with our contract manufacturers, our product development and
commercialization efforts could be delayed or stopped.



We
entered into a master services agreement with R.P. Scherer West, Inc., which was subsequently acquired by Cardinal Health, Inc., for the manufacture of commercial quantities of Vitrase. We also intend to use a contract manufacturer to assist us in
the development and manufacture of the new package configuration of Vitrase. We also have entered into a manufacturing services agreement with Bausch & Lomb Incorporated for the manufacture of commercial quantities of Istalol and, if approved,
Xibrom. To date, we have needed these products only in amounts sufficient for clinical trials. Before any contract manufacturer can produce commercial quantities of a product, we must demonstrate to the FDAs satisfaction that the product
source for commercial quantities is substantially equivalent to the supply of the product used in our clinical trials. Such demonstration may include the requirement to conduct additional clinical trials. In addition, the manufacturing facilities



17



---

##### Table of Contents

of all of our contract manufacturers must comply with current Good Manufacturing Practice regulations, which the FDA
strictly enforces. Moreover, the facilities of the contract manufacturer must undergo and pass pre-approval inspections by the FDA before any of our products can be approved for commercial manufacture and, once approved, such facilities must
maintain their compliance and good standing with regulatory authorities. We cannot assure you that R.P. Scherer West, Bausch & Lomb, or any other manufacturer we may contract with in the future will be able, as applicable, to develop processes
necessary to produce substantially equivalent product that regulatory authorities will approve them as a manufacturer or that such facilities, once approved, will maintain their compliance and good standing with regulatory authorities. Failure to
achieve or maintain any of the foregoing could delay or stop our efforts to develop our product candidates and commercialize our products.



Our marketing partners may terminate, or fail to perform their duties under, our agreements, in which case our ability to commercialize our products may be
significantly impaired.



We have entered into
collaborations with Senju relating to Istalol and Xibrom and Allergan and Otsuka Pharmaceuticals relating to Vitrase for ophthalmic uses for the posterior region of the eye. We are currently dependent on Allergan for the commercialization of Vitrase
for any such uses worldwide, except for Japan. We depend on Otsuka for obtaining regulatory approval of Vitrase for any such uses in Japan, and if such approval is obtained, we will be dependent upon Otsuka for the commercialization of Vitrase for
such approved uses in Japan. The amount and timing of resources that Allergan, Otsuka, and Senju dedicate to our collaborations is not within our control. Accordingly, any breach or termination of our agreements by, or disagreements with, these
collaborators could delay or stop the development and/or commercialization of our product candidates, or adversely impact our receipt of milestone payments, profit splits, royalties, and other consideration from these collaborations. Our
collaborative partners may change their strategic focus, terminate our agreements on relatively short notice, or pursue alternative technologies. Although our agreements with Allergan, Otsuka and Senju contain reciprocal terms providing that neither
we nor they may develop products that directly compete in the same form with the products involved in the collaboration, there can be no assurances that our collaborators will not develop competing products in different forms or products that
compete indirectly with our products. Accordingly, unfavorable developments relating to our strategic partners could have a significant adverse effect on us and our financial condition. See also the Risk Factor entitled Even though we obtained
FDA approval of the Vitrase NDA for use as a spreading agent, our ability to commercialize Vitrase for such use is dependent upon the terms of our collaboration with Allergan.



If we have problems with our sole source suppliers, our product development and commercialization efforts for our product candidates
could be delayed or stopped.



Some materials used in our
products are currently obtained from a single source. Biozyme Laboratories, Ltd. is currently our only source for highly purified ovine hyaluronidase, which is the active ingredient in Vitrase. Commercial quantities of Vitrase will be supplied by
R.V. Scherer West as the sole source manufacturer. Both Istalol and, if approved, Xibrom will be supplied by Bausch & Lomb.



We have not established and may not be able to establish arrangements with additional suppliers for these ingredients or products. Difficulties in our
relationship with our suppliers or delays or interruptions in such suppliers supply of our requirements could limit or stop our ability to provide sufficient quantities of our products, on a timely basis, for clinical trials and, if our
products are approved, could limit or stop commercial sales, which would have a material adverse effect on our business and financial condition. While we are currently pursuing additional sources for these products and materials, our success in
establishing such additional supply arrangements cannot be assured.



We
depend on our Chief Executive Officer, Vicente Anido, Jr., Ph.D., and other key personnel, to execute our strategic plan to transition to a commercial-stage company.



Our success largely depends on the skills, experience and efforts of our key personnel, including Chief Executive Officer,
Vicente Anido, Jr., Ph.D. We have entered into a written employment agreement with Dr. Anido that can be terminated at any time by us or by Dr. Anido. In the event Dr. Anidos employment is terminated, other than for cause or voluntarily by Dr.
Anido, Dr. Anido will receive nine months of salary as severance compensation. In the event Dr. Anidos employment is terminated after a change of control, other than for cause or voluntarily by Dr. Anido, then Dr. Anidos stock options
will immediately vest and become exercisable in full, and Dr. Anido will receive twenty-four months of salary as severance compensation. We do not maintain key person life insurance policies covering Dr. Anido. The loss of Dr. Anido, or
our failure to retain other key personnel, would jeopardize our ability to execute our strategic plan and materially harm our business.

Risks Related to Our Industry



Compliance with the extensive government regulations to which we are subject is expensive and time consuming, and may result in the delay
or cancellation of product sales, introductions or modifications.



Extensive industry regulation has had, and will continue to have, a significant impact on our business. All pharmaceutical companies, including us, are subject to extensive, complex, costly and evolving regulation by the federal government,
principally the FDA and to a lesser extent by the U.S. Drug Enforcement Administration (DEA), and foreign and state government agencies. The Federal Food, Drug and Cosmetic Act, the Controlled Substances Act and other domestic and
foreign statutes and regulations govern or influence the testing, manufacturing, packing, labeling, storing, record keeping, safety, approval, advertising, promotion, sale and distribution of our products. Under certain of these regulations, we and
our contract suppliers and manufacturers are subject to periodic inspection of our or their respective facilities, procedures and operations and/or the testing of our products by the FDA, the DEA and other authorities, which conduct periodic
inspections to confirm that we and our contract suppliers and manufacturers are in compliance with all applicable regulations. The FDA also conducts pre-approval and post-approval reviews and plant inspections to determine whether our systems, or
our contract suppliers and manufacturers processes, are in compliance with cGMP and other FDA regulations.



In addition, the FDA imposes a number of complex regulatory requirements on entities that advertise and promote pharmaceuticals, including, but not
limited to, standards and regulations for direct-to-consumer advertising, off-label promotion, industry sponsored scientific and educational activities, and promotional activities involving the Internet.



We are dependent on receiving FDA and other governmental approvals prior to
manufacturing, marketing and shipping our products. Consequently, there is always a risk that the FDA or other applicable governmental authorities will not approve our products, or will take post-approval action limiting or revoking our ability to
sell our products, or that the rate, timing and cost of such approvals will adversely affect our product introduction plans or results of operations.



Our suppliers and manufacturers are subject to regulation by the FDA and other agencies, and if they do not meet their commitments, we would have to find substitute
suppliers or manufacturers, which could delay or prevent the supply of our products to market.



Regulatory requirements applicable to pharmaceutical products make the substitution of suppliers and manufacturers costly and time consuming. We have no
internal manufacturing capabilities and are, and expect to be in the future, entirely dependent on contract manufacturers and suppliers for the manufacture of our products and for their active and other ingredients. The disqualification of these
suppliers through their failure to comply with regulatory requirements could negatively impact our business because the delays and costs in obtaining and qualifying alternate suppliers (if such alternative suppliers are available, which we cannot
assure) could delay clinical trials or otherwise inhibit our ability to bring approved products to market or could result in a delay or disruption in the manufacture, marketing or sales of our products, which would have a material adverse affect on
our business and financial condition.



We may be required to initiate or
defend against legal proceedings related to intellectual property rights, which may result in substantial expense, delay and/or cessation of our development and commercialization of our products.



We rely on patents to protect our intellectual property rights. The strength
of this protection, however, is uncertain. For example, it is not certain that:



| |  | our patents and pending patent applications cover products and/or technology that we invented first;
| | - | ----------------------------------------------------------------------------------------------------



| |  | we were the first to file patent applications for these inventions;
| | - | -------------------------------------------------------------------



| |  | others will not independently develop similar or alternative technologies or duplicate our technologies;
| | - | --------------------------------------------------------------------------------------------------------



| |  | any of our pending patent applications will result in issued patents; and
| | - | -------------------------------------------------------------------------



| |  | any of our issued patents, or pending patent applications that result in issued patents, will be held valid and infringed in the event the patents are asserted against others.
| | - | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



We currently own or license 25 U.S. and foreign
patents and 49 U.S. and foreign pending patent applications. There can be no assurance that our existing patents, or any patents issued to us as a result of such applications, will provide a basis



19

for commercially viable products, will provide us with any competitive advantages, or will not face third-party
challenges or be the subject of further proceedings limiting their scope or enforceability. We may become involved in interference proceedings in the U.S. Patent and Trademark Office to determine the priority of our inventions. In addition, costly
litigation could be necessary to protect our patent position. We license patents held by the Eastern Virginia Medical School for Caprogel and Senju for Istalol and Xibrom. Some of these license agreements do not permit us to control the prosecution,
maintenance, protection and defense of such patents. If the licensor chooses not to protect its own patent rights, we may not be able to take actions to secure our related product marketing rights. In addition, if such patent licenses are terminated
before the expiration of the licensed patents, we may no longer be able to continue to manufacture and sell such products as may be covered by the patents.



We also rely on trademarks to protect the names of our products. These trademarks may be challenged by others. If we enforce our trademarks against third
parties, such enforcement proceedings may be expensive. We have exclusively licensed the trademark Vitrase to Allergan under our collaboration agreement. Some of our other trademarks, including Caprogel and Xibrom, are owned by or assignable to our
licensors Eastern Virginia Medical School and Senju, and upon expiration or termination of the license agreements, we may no longer be able to use these trademarks.



We also rely on trade secrets, unpatented proprietary know-how and continuing technological innovation that we seek to
protect with confidentiality agreements with employees, consultants and others with whom we discuss our business. Disputes may arise concerning the ownership of intellectual property or the applicability or enforceability of these agreements, and we
might not be able to resolve these disputes in our favor.



In
addition to protecting our own intellectual property rights, third parties may assert patent, trademark or copyright infringement or other intellectual property claims against us based on what they believe are their own intellectual property rights.
We may be required to pay substantial damages, including but not limited to treble damages, for past infringement if it is ultimately determined that our products infringe a third partys intellectual property rights. Even if infringement
claims against us are without merit, defending a lawsuit takes significant time, may be expensive and may divert managements attention from other business concerns. Further, we may be stopped from developing, manufacturing or selling our
products until we obtain a license from the owner of the relevant technology or other intellectual property rights. If such a license is available at all, it may require us to pay substantial royalties or other fees.



If third-party reimbursement is not available, our products may not be accepted in the
market.



Our ability to earn sufficient returns on our
products will depend in part on the extent to which reimbursement for our products and related treatments will be available from government health administration authorities, private health insurers, managed care organizations and other healthcare
providers.



Third-party payers are increasingly attempting to
limit both the coverage and the level of reimbursement of new drug products to contain costs. Consequently, significant uncertainty exists as to the reimbursement status of newly approved healthcare products. Third-party payers may not establish
adequate levels of reimbursement for any of our approved products or products we develop or acquire in the future, which could limit their market acceptance and result in a material adverse effect on our financial condition.



The rising cost of healthcare and related pharmaceutical product pricing has lead to
cost-containment pressures that could cause us to sell our products at lower prices, resulting in less revenue to us.



Any of our products that have been or in the future are approved by the FDA may be purchased or reimbursed by state and federal government authorities,
private health insurers and other organizations, such as health maintenance organizations and managed care organizations. Third party payors increasingly challenge pharmaceutical product pricing. The trend toward managed healthcare in the United
States, the growth of such organizations, and various legislative proposals and enactments to reform healthcare and government insurance programs, including the Medicare Prescription Drug Modernization Act of 2003, could significantly influence the
manner in which pharmaceutical products are prescribed and purchased, resulting in lower prices and/or a reduction in demand. Such cost containment measures and healthcare reforms could adversely affect our ability to sell our products. Furthermore,
individual states have become increasingly aggressive in passing legislation and implementing regulations designed to control pharmaceutical product pricing, including price or patient reimbursement constraints, discounts, restrictions on certain
product access, importation from other countries and bulk purchasing. Legally mandated price controls on payment amounts by third party payors or other restrictions could negatively and materially impact our revenues and financial condition. We
anticipate that we will encounter similar regulatory and legislative issues in most other countries outside the United States.

##### Table of Contents

We face intense competition and rapid technological change that could result in the development of products by others
that are superior to the products we are developing.



We
have numerous competitors in the United States and abroad, including, among others, major pharmaceutical and specialized biotechnology firms, universities and other research institutions that may be developing competing products. Such competitors
may include Allergan, Alcon Laboratories, Inc., Bausch & Lomb, Novartis AG, Pfizer, Inc. and Eli Lilly and Company. These competitors may develop technologies and products that are more effective or less costly than our current or future
products or product candidates or that could render our technologies, products and product candidates obsolete or noncompetitive. Many of these competitors have substantially more resources and product development, manufacturing and marketing
experience and capabilities than we do. Many of our competitors also have more resources committed to and expertise in effectively commercializing, marketing, and promoting products approved by the FDA, including communicating the effectiveness,
safety and value of the products to actual and prospective customers and medical professionals. In addition, many of our competitors have significantly greater experience than we do in undertaking preclinical testing and clinical trials of
pharmaceutical product candidates and obtaining FDA and other regulatory approvals of products and therapies for use in healthcare.



We are exposed to product liability claims, and insurance against these claims may not be available to us on reasonable terms or at all.



The design, development, manufacture and sale of our products involve an
inherent risk of product liability claims by consumers and other third parties. As we begin to commercialize, market, and promote our approved products, like Vitrase for use as a spreading agent and Istalol, we may be subject to various product
liability claims. In addition, we may in the future recall or issue field corrections related to our products due to manufacturing deficiencies, labeling errors or other safety or regulatory reasons. We cannot assure you that we will not experience
material losses due to product liability claims, product recalls or corrections. These events, among others, could result in additional regulatory controls, such as the performance of costly post-approval clinical studies or revisions to our
approved labeling that could limit the indications or patient population for our products or could even lead to the withdrawal of a product from the market. Furthermore, any adverse publicity associated with such an event could cause consumers to
seek alternatives to our products, which may cause our sales to decline, even if our products are ultimately determined not to have been the primary cause of the event.



We currently maintain sold products and clinical trial liability insurance with per occurrence and aggregate coverage limits
of $10 million. The coverage limits of our insurance policies may be inadequate to protect us from any liabilities we might incur in connection with clinical trials or the sale of our products. Product liability insurance is expensive and in the
future may not be available on commercially acceptable terms, or at all. A successful claim or claims brought against us in excess of our insurance coverage could materially harm our business and financial condition.



Risks Related to Our Stock



Our stock price is subject to significant volatility.



Since 2001 until the present, the daily closing price per share of our
common stock has ranged from a high of $133.75 per share to a low of $2.60 per share, as adjusted for the 1-for-10 reverse stock split effected November 2002. Our stock price has been and may continue to be subject to significant volatility. The
following factors, in addition to other risks and uncertainties described in this section may cause the market price of our common stock to fall:



| |  | the scope, outcome and timeliness of any governmental, court or other regulatory action that may involve us, including, without limitation, the scope, outcome or timeliness of any
inspection or other action of the FDA;
| | - | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  | market acceptance and demand for our approved products;
| | - | -------------------------------------------------------



| |  | the availability to us, on commercially reasonable terms or at all, of third-party sourced products and materials;
| | - | ------------------------------------------------------------------------------------------------------------------



| |  | timely and successful implementation of our strategic initiatives, including the expansion of our commercial infrastructure to support the marketing and sale of our products;
| | - | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  | developments concerning proprietary rights, including the ability of third parties to assert patents or other intellectual property rights against us which, among other things,
could cause a delay or disruption in the development, manufacture, marketing or sale of our products;
| | - | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| |  | competitors publicity regarding actual or potential products under development or new commercial products, and the impact of competitive products and pricing;
| | - | ---------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  | period-to-period fluctuations in our financial results;
| | - | -------------------------------------------------------



| |  | public concern as to the safety of new technologies;

| |  | comments made by securities analysts; or
| | - | ----------------------------------------



| |  | economic and other external factors, including disasters and other crises.
| | - | --------------------------------------------------------------------------



We participate in a highly dynamic industry, which often results in significant volatility in the market price of our common stock irrespective of company
performance. Fluctuations in the price of our common stock may be exacerbated by conditions in the healthcare and technology industry segments or conditions in the financial markets generally.



Trading in our stock over the last 12 months has been limited, so investors may not be
able to sell as much stock as they want at prevailing prices.



The average daily trading volume in our common stock for the twelve-month period ended June 30, 2004 was approximately 57,041 shares, and the average daily number of transactions was approximately 133 for the same period. If limited trading
in our stock continues, it may be difficult for investors to sell their shares in the public market at any given time at prevailing prices.



Future sales of shares of our common stock may negatively affect our stock price.



As a result of our bridge financing in September 2002, our PIPE financing transaction in November 2002, and our follow-on
public offering in November 2003, we issued approximately 15.6 million shares of our common stock. The shares of common stock issued in connection with these transactions represents approximately 89% of our common stock as of June 30, 2004. In
connection with our bridge financing and our PIPE financing transaction, we also issued warrants exercisable for the purchase of up to an aggregate of 1,842,104 shares of our common stock based upon a purchase price of $3.80 per share. We filed a
registration statement on Form S-3 (Registration No. 333-103820), which was declared effective on June 6, 2003, to cover sales of the shares issued to the PIPE investors and issuable to the PIPE and bridge investors upon conversion of the warrants.
The exercise of these warrants could result in significant dilution to our shareholders at the time of exercise. We also filed a registration statement on Form S-2 (Registration No. 333-109576) in connection with our follow-on public offering, which
was declared effective on November 12, 2003, in which we issued and sold 4,000,000 shares of our common stock. On April 23, 2004 we filed a universal shelf registration statement on Form S-3 (Registration No. 333-114815) with the Securities and
Exchange Commission providing for the offering from time to time of up to $75,000,000 of our securities, which may consist of common stock, preferred stock, warrants, or debt securities. This registration statement also includes up to 3,600,000
shares of our common stock to be offered by certain selling stockholders.



In the future, we may issue additional shares of common stock or other equity securities, including but not limited to options, warrants or other derivative securities convertible into our common stock, which could
result in significant dilution to our shareholders.



Concentration of
ownership and contractual board rights could delay or prevent a change in control or otherwise influence or control most matters submitted to our stockholders and will be able to exert control over us and our significant corporate decisions.



Our directors, officers, and principal stockholders
together control approximately 64.9% of our voting securities, a concentration of ownership that could delay or prevent a change in control. Our executive officers and directors beneficially own approximately 4.8% of our voting securities and our 5%
or greater stockholders beneficially own approximately 60.1% of our voting securities. We are obligated to include a representative of each of Allergan and Investor Growth Capital as a nominee for election to the Board of Directors, and Sprout
Capital has the right to designate two such nominees. These stockholders, if acting together, would be able to influence and possibly control most matters submitted for approval by our stockholders, including the election of directors, delaying or
preventing a change of control, and the consideration of transactions in which stockholders might otherwise receive a premium for their shares over then-current market prices.

Our shareholder rights plan, provisions in our charter documents, and Delaware law may inhibit a takeover of us, which
could limit the price investors might be willing to pay in the future for our common stock, and could entrench management.



We have a shareholder rights plan that may have the effect of discouraging unsolicited takeover proposals, thereby entrenching current management and
possibly depressing the market price of our common stock. The rights issued under the shareholder rights plan would cause substantial dilution to a person or group that attempts to acquire us on terms not approved in advance by our board of
directors. In addition, our charter and bylaws contain provisions that may discourage unsolicited takeover proposals that stockholders may consider to be in their best interests. These provisions include:



| |  | a classified board of directors;
| | - | --------------------------------



| |  | the ability of the board of directors to designate the terms of and issue new series of preferred stock;
| | - | --------------------------------------------------------------------------------------------------------



| |  | advance notice requirements for nominations for election to the board of directors; and
| | - | ---------------------------------------------------------------------------------------



| |  | special voting requirements for the amendment of our charter and bylaws.
| | - | ------------------------------------------------------------------------



We are also subject to anti-takeover provisions under Delaware law, each of which could delay or prevent a change of control. Together these provisions
and the shareholder rights plan may make more difficult the removal of management and may discourage transactions that otherwise could involve payment of a premium over prevailing market prices for common stock.



We do not anticipate declaring any cash dividends on our common stock.



We have never declared or paid cash dividends on our common stock and do not
plan to pay any cash dividends in the near future. Our current policy is to retain all funds and any earnings for use in the operation and expansion of our business.



Item 3 Quantitative and Qualitative Disclosures about Market Risk



The primary objective of our investment activities is to preserve principal while at the same time maximizing the income we receive from our investments without significantly increasing risk. Some of the securities
that we invest in may have market risk. This means that a change in prevailing interest rates may cause the principal amount of the investment to fluctuate. For example, if we hold a security that was issued with a fixed interest rate at the
then-prevailing rate and the prevailing interest rate later rises, the principal amount of our investment will probably decline. To minimize this risk in the future, we intend to maintain our portfolio of cash equivalents and short-term investments
in a variety of securities, including commercial paper, money market funds, government and non-government debt securities. The average duration of all of our investments in 2003 and for the three months of 2004 was less than one year. Due to the
short-term nature of these investments, we believe we have no material exposure to interest rate risk arising from our investments. A hypothetical 100 basis point adverse move in interest rates along the entire interest rate yield curve would not
materially affect the fair market value of our interest sensitive financial investments. Declines in interest rates over time will, however, reduce our investment income, while increases in interest rates over time will increase our interest
expense. Historically, and as of June 30, 2004, we have not used derivative instruments or engaged in hedging activities.



We have operated primarily in the United States and have had no sales to date. Accordingly, we have not had any significant exposure to foreign currency
rate fluctuations. Visionexs functional currency is the Singapore dollar and a portion of Visionexs business was conducted in currencies other than the Singapore dollar prior to the wind down of operations in July 2002. As a result,
currency fluctuations between the Singapore dollar and the currencies in which Visionex had done business will cause foreign currency translation gains and losses. We do not expect our foreign currency translation gains or losses to be material. We
do not currently engage in foreign exchange hedging transactions to manage our foreign currency exposure.

From
time to time, we may be involved in litigation relating to claims arising out of our operations in the normal course of business. We currently are not a party to any legal proceedings, the adverse outcome of which, in managements opinion,
