IS
TA Pharmaceuticals, Inc.

Notes to Unaudited Condensed Consolidated Financial Statements

March 31, 2005



1. The Company



ISTA Pharmaceuticals, Inc. (ISTA or the Company) was incorporated in the state of California on February 13, 1992 to discover,
develop and market new remedies for diseases and conditions of the eye. The Company reincorporated in Delaware on August 4, 2000. Vitrase®, Istalol®, Xibrom, Caprogel®, ISTA®, ISTA Pharmaceuticals® and the ISTA logo are our trademarks, either owned or under license.



ISTA is a specialty pharmaceutical company focused on the development and commercialization of unique and uniquely improved
products for serious diseases and conditions of the eye. Since the Companys inception, it has devoted its resources primarily to fund research and development programs, late-stage product acquisitions and product commercial launches. In
December 2001, ISTA announced its strategic plan to transition from a development-stage organization to a specialty pharmaceutical company with a primary focus on ophthalmology. In July 2004, the Company transitioned from a development-stage
organization to a commercial entity.



As of March 31, 2005, the
Company had approximately $67.1 million in cash and cash equivalents and short-term investments. The Company incurred a net loss of $8.2 million for the three months ended March 31, 2005 and had an accumulated deficit of $196.3 million at March 31,
2005. 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 attain profitable operations is dependent upon 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 on hand 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 (PIPE) financings, and various other 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 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 the Company 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, 2004.



3. Revenue Recognition



Product revenue.The Company recognizes revenue from product sales, in accordance with Financial Accounting Standard,
or FAS, No. 48 Revenue Recognition When Right of Return Exists, when there is persuasive evidence that an arrangement exists, when title has passed, the price is fixed or determinable, and the Company is reasonably assured of

collecting the resulting receivable. The Company recognizes product revenue net of estimated allowances for discounts, returns, rebates and chargebacks. Such
estimates require the most subjective and complex judgement due to the need to make estimates about matters that are inherently uncertain. Actual results may differ significantly from the Companys estimates. Changes in estimates and
assumptions based upon actual results may have a material impact on the Companys results of operations and/or financial condition.



In general, the Company is obligated to accept from customers the return of pharmaceuticals that have reached their expiration date. The Company
authorizes returns for damaged products and exchanges for expired products in accordance with its return goods policy and procedures, and has established reserves for such amounts at the time of sale. The Company recently launched its first marketed
product, Istalol, in the third quarter of 2004 and its second product, Vitrase, in the first quarter of 2005. Actual Istalol and Vitrase returns have not exceeded the Companys estimated allowances for returns.



License revenue.The Company recognizes revenue consistent with the
provisions of the Securities and Exchange Commissions Staff Accounting Bulletin, or SAB, No. 104, 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 product and technology license fees under multiple-element arrangements are deferred and recognized over the period of such services or performance if such arrangements require
on-going services or performance. Amounts received for milestones are recognized upon achievement of the milestone, unless the amounts received are creditable against royalties or the Company has ongoing performance obligations. 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 the Companys revenue recognition criteria
will be recorded as deferred revenue in the accompanying balance sheets.



4.
Inventory



Inventory at March 31, 2005 consisted of
$262,000 of raw materials and $1.5 million of finished goods. Additionally, the Company recorded $944,000 in inventory reserves. The Company had no inventory at March 31, 2004. The Company obtained FDA approval for Vitrase for use as a spreading
agent in May 2004 and Istalol in June 2004.



Inventory consists
of currently marketed products. Inventory primarily represents raw materials used in production and finished goods inventory on hand, valued at standard cost. Inventories are reviewed periodically for slow-moving or obsolete status. If a launch of a
new product is delayed, inventory may not be fully utilized and could be subject to impairment, at which point the Company would record a reserve to adjust inventory to its net realizable value.



Inventory relates to both Istalol, for the treatment of glaucoma, Vitrase,
lyophilized 6,200 USP units multi-purpose vial and Vitrase 200 USP units/mL for use as a spreading agent to facilitate the absorption and dispersion of other injected drugs. Inventories, net of allowances, are stated at the lower of cost or market.
Cost is determined by the first-in, first-out method.



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 three-month period ended March 31, 2005 and 2004 was $8,231,000 and $5,225,000, 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 than 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 Option 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 the employee stock 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 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. The Company granted restricted stock awards to non-employee directors to purchase 7,500 shares of common stock at a
purchase price of $0.001 per share, which awards are subject to forfeiture until the first anniversary of the grant date.



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.



9. Recent Accounting Pronouncements



In December 2004, the FASB issued Statement No. 123R (Revised 2004), Share-Based Payment. The revisions to SFAS No 123 require compensation costs related to share-based payment transactions to be
recognized in the financial statements. With limited exceptions, the amount of compensation cost will be measured based on the grant-date fair value of the equity or liability instruments issued. In addition, liability awards will be re-measured
each reporting period. Compensation cost will be recognized over the period that an employee provides service in exchange for the award. Statement No. 123R replaces FASB Statement No. 123, Accounting for Stock Based Compensation, and
supersedes APB Opinion No. 25, Accounting for Stock Issued to Employees. For public entities, the provisions of the statement are effective as of the beginning of the first annual reporting period that begins after December 15, 2005,
however early adoption is allowed. The Company expects to adopt the provisions of the new statement in the first fiscal quarter of 2006. The adoption of SFAS No. 123Rs fair value method will have a significant impact on the Companys
results of operations, although it will have no impact on the Companys overall financial position. The Company cannot accurately estimate at this time the impact of adopting SFAS No. 123R as it will depend on its market price, the
Companys assumptions used and levels of share-based payments granted in future periods.



In November 2004, the FASB issued SFAS No. 151,  Inventory Costs - an amendment of ARB No. 43, Chapter 4. SFAS 151 amends the guidance in Accounting Research Bulletin No. 43, Chapter 4, Inventory Pricing,
to clarify that abnormal amounts of idle facility expense, freight, handling costs and wasted material (spoilage) are to be recognized as current-period charges. SFAS 151 is effective for fiscal years beginning after June 15, 2005. SFAS 151 is not
expected to have a material impact on the Companys financial statements.

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 recently launched in the United States our first product, Istalol for the treatment of glaucoma, and our second product, Vitrase for use as a spreading agent. In addition, we have received approval for our New Drug Application, or
NDA, with the U.S. Food and Drug Administration, or FDA, for Xibrom for the treatment of ocular inflammation following cataract surgery. We also have one NDA on file with the FDA for Vitrase for the treatment of vitreous hemorrhage for which we
received an approvable letter.



We continue to expand our
commercial infrastructure in connection with the marketing, sale and distribution of our approved products in the United States. We estimate that approximately 10,000 ophthalmologists write the majority of the prescriptions for serious conditions of
the eye in the United States. In connection with our recent launch of Vitrase, we have expanded our sales force to approximately 50 sales representatives as of March 31, 2005 to better reach this physician population. We further intend to expand our
sales force to approximately 70 persons in conjunction with our U.S. launch of Xibrom. 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.



In January 2005, we sold 6,325,000 shares of our common stock
under our universal shelf registration statement in an underwritten public offering for an aggregate purchase price of $56.2 million, or $8.88 per share, before offering expenses and underwriting discounts. We intend to use the proceeds to finance
potential acquisitions and licensing of complementary businesses, assets, technologies and products that we may consider from time to time; and fund the continued development of our product candidates, the expansion of our commercial infrastructure
to commercialize our approved products and other general corporate purposes, including working capital.



While we currently have two products available for sale and a third product that was recently approved, we have not generated any significant revenues
from sales of our products. We have incurred losses since inception and had an accumulated deficit of $196.3 million through March 31, 2005. Our losses have resulted primarily from research and development activities, including clinical trials,
related general and administrative expenses, a deemed dividend to holders of our preferred stock which is no longer outstanding, and increased selling, general and administrative expenses related to the expansion of our commercial infrastructure. In
addition, we expect our operating expenses to increase substantially from historical levels in connection with our continued expansion of our commercial infrastructure to support the manufacture, marketing, sale and distribution of our approved
products. As a result, we expect to continue to incur operating losses for the foreseeable future until we are able to generate sufficient product revenues to support our then current cost structure.



Our Product Pipeline



We are pursuing the development of several late-stage products, including:



Vitrase (ovine hyaluronidase)



We recently received approval of, and have launched, Vitrase, our
proprietary formulation of ovine hyaluronidase, for use as a spreading agent. We also are developing Vitrase for the treatment of vitreous hemorrhage and diabetic retinopathy. The term hyaluronidase describes a group of naturally occurring enzymes
that can digest certain forms of carbohydrate molecules called proteoglycans. Vitrase, when used as a spreading agent, is injected into connective tissue, where it modifies the permeability of such tissues and promotes diffusion of injected drugs,
thus accelerating their absorption. When injected into the vitreous humor, Vitrase breaks down the proteoglycan matrix, causing the vitreous humor to liquefy. We believe that this also results in the separation of the vitreous humor from the retina
and that, together, these effects are beneficial for the treatment of vitreous hemorrhage and diabetic retinopathy. Vitrase may be administered directly into the vitreous humor through a single-dose injection. The procedure will be performed in
several minutes in an ophthalmologists office and is virtually painless due to the application of a topical anesthetic.



Spreading Agent



Hyaluronidase has been found to be a spreading or diffusing substance, which modifies the permeability of connective tissue through the hydrolysis of
hyaluronic acid, a polysaccharide found in the intercellular ground substance of connective tissue, and of certain specialized tissues, such as the umbilical cord and vitreous humor. Hyaluronidase temporarily decreases the viscosity of the cellular
cement and promotes diffusion of injected drugs, thus facilitating their absorption.



10

##### Table of Contents

When no spreading agent is present, material injected subcutaneously spreads very slowly, but
hyaluronidase causes rapid spreading, provided local interstitial pressure is adequate to furnish the necessary mechanical impulse. Such an impulse is normally initiated by injected solutions. The rate of diffusion is proportionate to the amount of
enzyme, and the extent is proportionate to the volume of solution. When a spreading agent is administered with anesthesia, it speeds the onset of the anesthetic effect thereby reducing the time required for ocular surgery.



Market opportunity.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 in the United States each year, of which 2,600,000 are cataract surgeries. In addition to uses in ophthalmology, potential uses for
spreading agents include oncology, plastic surgery, pain management and pediatrics.



We have launched Vitrase in the United States for use as a spreading agent and are currently promoting it through our specialty sales force. We have targeted the top ophthalmic surgeons, many of whom are also high
prescribers of glaucoma medications that we currently target for Istalol. In order to support the launch of Vitrase, we have expanded our sales force to approximately 50 people as of the end of the first quarter of 2005.



Clinical/regulatory status.In May 2004, the FDA approved our NDA for
Vitrase, in a lyophilized 6,200 USP units multi-purpose vial, for use as a spreading agent to facilitate the absorption and dispersion of other injected drugs. In October 2004, the FDA informed us that Vitrase for use as a spreading agent was
entitled to five-year new chemical market exclusivity under the federal Food, Drug and Cosmetic Act. In December 2004, the FDA approved our supplemental NDA for Vitrase for use as a spreading agent at a concentration of 200 USP units/mL in sterile
solution.



Istalol (timolol)



Istalol is our once-a-day, eye drop solution of timolol, a beta-blocking
agent for the treatment of glaucoma. The product was developed by Senju Pharmaceuticals Co., Ltd. in Japan. In May 2002, we acquired marketing rights for Istalol in the United States under a license agreement with Senju. We received FDA approval of
Istalol in June 2004 and launched Istalol in the United States in the third quarter of 2004.



Glaucoma



Glaucoma is a
chronic disease that gradually reduces eyesight without warning and often without symptoms. If undetected and untreated, glaucoma can lead to irreversible eye damage and eventual blindness. According to the Glaucoma Research Foundation, in the
United States glaucoma is the cause of an estimated 9-12% of all blindness cases and is the second leading cause of blindness. Currently, its causes are not well understood and there is no cure.



Market opportunity.According to the Glaucoma Research Foundation,
three million people in the United States suffer from the disease, with 120,000 new cases documented annually. According to prescription data compiled by IMS Health for 2004, we estimate that the U.S. pharmaceutical market for the treatment of
glaucoma exceeds $1.3 billion per year. Of this, the ophthalmic beta-blocker market exceeds $174.3 million per year, primarily at generic prices, with over 5.4 million prescriptions written annually. Timolol maleate, which is currently available
from several manufacturers in either a twice-a-day eye drop solution or once-a-day gel formulation, 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 timolol maleate solution, given twice-a-day. Other than Istalol, the only available formulations of timolol maleate which have demonstrated efficacy with once a day dosing are gels, which have been known to cause blurring of
patients vision.



We launched Istalol in July 2004, and
currently promote it through our specialty sales force. Istalol promotion is now focused on the 7,000 ophthalmologists whom we believe account for more than 68% of all glaucoma prescriptions.



Clinical/regulatory status.Senju submitted an NDA for Istalol for the
treatment of glaucoma to the FDA in September 2002 that was accepted for review in November 2002. In June 2004, the FDA approved the NDA for Istalol. In October 2004, the FDA granted Istalol a BT rating, which means that prescriptions of
Istalol cannot be legally substituted at pharmacies with generic timolol maleate solutions.



Xibrom (bromfenac)



Xibrom is a topical non-steroidal anti-inflammatory formulation of bromfenac for the treatment of ocular inflammation. Approved by the FDA in March 2005, the product was first developed by Senju and launched in the Japanese market in 2000.
We believe its sales growth in Japan is principally due to its superior potency and twice-daily dosing

##### Table of Contents

regimen, as compared to the requirement of four doses-per-day for most other anti-inflammatory products. In May 2002, we acquired marketing rights for Xibrom
in the United States under a license agreement with Senju.



Ocular
Inflammation



Market opportunity.Based upon 2004
data from IMS Health, we estimate that over 8.6 million prescriptions are written annually for topical ophthalmic anti-inflammatory agents, including steroids, non-steroid anti-inflammatory agents and combination drugs. Currently available
non-steroid treatments must be dosed four times a day as compared to Xibroms twice daily dosing.



Clinical/regulatory status.Senju completed clinical development of bromfenac in Japan and launched the product in Japan in 2000. In March 2005, we
received FDA approval for Xibrom for the treatment of ocular inflammation following cataract surgery.



Ecabet Sodium



We are developing ecabet sodium as a prescription eye drop for the treatment of dry eye syndrome. Ecabet sodium represents a new class of molecules that increases the quantity and quality of mucin produced by conjunctival goblet cells and
corneal epithelia. Mucin is a glycoprotein component of tear film that lubricates while retarding moisture loss from tear evaporation. Ecabet sodium is currently marketed in Japan as an oral agent for treatment of gastric ulcers and gastritis. In
November 2004, we acquired U.S. marketing rights to ecabet sodium for the treatment of dry eye syndrome in the United States under a license agreement with Senju.



Dry Eye Syndrome



According to the National Eye Institute, dry eye syndrome (keratoconjunctivities sicca or KCS) is defined as a disorder of the tear film due to the tear
deficiency or excessive tear evaporation which causes damage to the interpalpebral (the exposed area between the upper and lower eye lids) ocular surface and is associated with symptoms of ocular discomfort. Dry eye syndrome has been linked with a
number of factors, including age, hormonal changes, ocular disease, medications that disrupt tear secretion or blinking, and autoimmune diseases such as lupus and rheumatoid arthritis. In severe cases of dry eye syndrome, scarring develops that may
lead to blindness.



Market opportunity.Based on data
compiled from various publicly available sources, we estimate that annual sales in the U.S. prescription dry eye market are expected to be approximately $95 million in 2004 and are anticipated to grow to approximately $350 to $700 million within
three to five years.



Clinical/regulatory status.Senju
has commenced Phase II testing of the product in Japan for the treatment of dry eye syndrome. In March 2005, we filed an Investigation New Drug Application, or IND, with the FDA to conduct a U.S. Phase IIb study of ecabet sodium for the treatment of
dry eye syndrome. We anticipate initiating our Phase IIb study in the second half of 2005. Based on timely completion of our Phase IIb study and depending upon the results, we expect to design and initiate two Phase III studies in 2006.



Tobramycin and prednisolone acetate Combination Product



We have developed a proprietary formulation of a fixed combination product
of tobramycin and prednisolone acetate (the tobra/pred product). The tobra/pred product is being developed for the treatment of steroid-responsive inflammatory ocular conditions where risk of bacterial infection exists.



Market opportunity.The tobra/pred product, if approved by the FDA,
will compete in the antibiotic steroid segment of the U.S. topical ophthalmic anti-inflammatory market. Based upon management estimates and 2004 prescription data compiled by IMS Health, we estimate that 2004 sales in the U.S. topical ophthalmic
anti-inflammatory market were approximately $400 million, with total prescriptions of 8.6 million. The combination antibiotic and steroid segment of the ophthalmic anti-inflammatory market has approximately a 45% share of the prescriptions, or about
3.8 million prescriptions according to data compiled by IMS Health.



Clinical/regulatory status.In April 2005, we filed an IND with the FDA to initiate a U.S. Phase III study of the tobra/pred product for the treatment of steroid-responsive inflammatory ocular conditions where risk of bacterial
infection exists. We expect to initiate our tobra/pred product Phase III study in the third quarter of 2005. Based on timely completion

of our Phase III study and depending on the results, we expect to submit to the FDA an NDA for the tobra/pred product during the first half of 2006.



Caprogel (aminocaproic acid)



Caprogel is a new topical gel formulation of aminocaproic acid for treating
hyphema. Hyphema is a term used to describe bleeding in the anterior chamber, the space between the cornea and the iris, of the eye and usually results from trauma to the eye. In May 2002, we acquired worldwide marketing rights for Caprogel, and we
are currently conducting feasibility studies for its reformulation and commercialization. Once completed, and if these studies yield promising results, we intend to pursue further clinical development consistent with such studies results.



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 and currently there is no available pharmaceutical agent approved for its treatment. Caprogel has received an orphan drug designation for the treatment of hyphema from
the FDA, which may result in a seven year market exclusivity privilege with respect to Caprogel, if approved.



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 15295 Alton
Parkway, Irvine, CA 92618, and our telephone number is (949) 788-6000.



We have incurred losses since inception and had an accumulated deficit of $196.3 million through March 31, 2005. 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 launch our approved products.



Critical Accounting Policies and Estimates



Managements discussion and analysis of financial condition and results of operations, as well as disclosures included elsewhere in this Report are based upon our consolidated financial statements, which have been prepared in
accordance with accounting principles generally accepted in the United States. Our significant accounting policies are described in the accompanying Notes to Consolidated Financial Statements. Included within these policies are our critical
accounting policies. Critical accounting policies are those policies that are most important to the preparation of our consolidated financial statements and require managements most subjective and complex judgment due to the need to make
estimates about matters that are inherently uncertain. Although we believe that our estimates and assumptions are reasonable, actual results may differ significantly from these estimates. Changes in estimates and assumptions based upon actual
results may have a material impact on our results of operations and/or financial condition.



We believe that the critical accounting policies that most impact the consolidated financial statements are as described below.



Revenue Recognition



Product Revenue.We recognize revenue from product sales, in accordance with Financial Accounting Standard No. 48 Revenue Recognition When
Right of Return Exists, when there is persuasive evidence that an arrangement exists, when title has passed, the price is fixed or determinable, and we are reasonably assured of collecting the resulting receivable. We recognize product revenue
net of estimated allowances for discounts, returns, rebates and chargebacks. If actual future payments for allowances for discounts, returns, rebates and chargebacks exceed the estimates we made at the time of sale, our financial position, results
of operations and cash flows would be negatively impacted. We are obligated to accept from customers the return of pharmaceuticals that have reached their expiration date. We authorize returns for damaged products and exchanges for expired products
in accordance with our return goods policy and procedures, and have established reserves for such amounts at the time of sale. We recently launched our first product, Istalol, in the third quarter of 2004 and our second product, Vitrase for use as a
spreading agent, in the first quarter of 2005. To date, actual Istalol and Vitrase returns have not exceeded our estimated allowances for returns. Although we believe that our estimates and assumptions are reasonable as of the date when made, actual
results may differ significantly from these estimates. Our financial position, results of operations and cash flows may be materially and negatively impacted if actual returns exceed our estimated allowances for returns.



13

##### Table of Contents

License Revenue.We recognize revenue consistent with the provisions of the Securities and
Exchange Commissions Staff Accounting Bulletin No. 104, 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 product and technology license fees under multiple-element arrangements are deferred and recognized over the period of such services or performance if such arrangements require on-going services or performance.
Amounts received for milestones are recognized upon achievement of the milestone, unless the amounts received are creditable against royalties or we have ongoing performance obligations. 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.



Inventories



Inventory consists of currently marketed products.
Inventory primarily represents raw materials used in production and finished goods inventory on hand, valued at standard cost. Inventories are reviewed periodically for slow-moving or obsolete status. If a launch of a new product is delayed,
inventory may not be fully utilized and could be subject to impairment, at which point the Company would record a reserve to adjust inventory to its net realizable value.



Inventory relates to both Istalol, for the treatment of glaucoma, Vitrase, lyophilized 6,200 USP units multi-purpose vial
and Vitrase 200 USP units/mL for use as a spreading agent to facilitate the absorption and dispersion of other injected drugs. Inventories, net of allowances, are stated at the lower of cost or market. Cost is determined by the first-in, first-out
method.



Income Taxes



We record a valuation allowance to reduce our deferred tax assets to the
amount that is more likely than not to be realized. While we have considered future taxable income and ongoing prudent and feasible tax planning strategies in assessing the need for the valuation allowance, in the event we were to determine that we
would be able to realize our deferred tax assets in the future in excess of its net recorded amount, an adjustment to the deferred tax asset would increase income in the period such determination was made.



Results of Operations



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



Three Months Ended March 31, 2005 and 2004



Revenue. Revenue was approximately $580,000 for the three months ended March 31, 2005, as compared to $69,000 for the three months ended March 31, 2004. In the third quarter of 2004, we launched our first commercial product, Istalol,
a once-a-day, eye drop solution of timolol, a beta-blocking agent for the treatment of glaucoma. In the first quarter of 2005, we launched our second commercial product, Vitrase, for use as a spreading agent. Net product sales for the three months
ended March 31, 2005 were $511,000. There were no product sales for the three months ended March 31, 2004.



In addition to product revenues during the three months ended March 31, 2005, we reported license revenue of $69,000 for both the three months ended March
31, 2005 and 2004, which reflects the amortization for the period of deferred revenue recorded in December 2001 for the license fee payment made by Otsuka Pharmaceuticals Co., Ltd. in connection with the license of Vitrase in Japan for ophthalmic
uses in the posterior region of the eye.



Cost of products
sold. Cost of products sold were $366,000 for the three months ended March 31, 2005. There was no product sales during the three months ended March 31, 2004. Cost of products sold for the first quarter of 2005 consisted primarily of inventory
reserves of $109,000 related to short dating of certain Istalol lots, $64,000 related to Vitrase freight charges, and $63,000 related to Vitrase distribution costs. Because the launch of Vitrase occurred in the middle of the quarter, we would expect
freight and distribution costs to decline as a percentage of sales as Vitrase sales grow over time. Product gross margin for the three months ended March 31, 2005 was $145,000, or 28%. We expect product gross margin to continue to improve throughout
2005 commensurate with our product sales growth.



Research
and development expenses.Research and development expenses for the three months ended March 31, 2005 were $2.4 million compared to $3.0 million for the three months ended March 31, 2004. 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. Research and



14

##### Table of Contents

development expenses decreased by $600,000 during the three months ended March 31, 2005 as compared to the three months ended March 31, 2004. This decrease
is attributable to a reduction in research and development expenses, primarily as a result of obtaining FDA approval for Vitrase, Istalol and Xibrom, which resulted in the capitalization of various amounts into commercial inventory, for the first
quarter of 2005 as compared to the prior period.



Selling,
general and administrative expenses.Selling, general and administrative expenses were $6.4 million for the three months ended March 31, 2005 compared to $2.4 million for the three months ended March 31, 2004. Of the $4.0 million increase in
selling, general and administrative expenses, $3.6 million relates to sales and marketing expenses associated with the commercial launch of our approved products, including an increase in sales personnel, and $400,000 is due to increases in
personnel expenses and other general corporate expenses principally related to facility costs, offset by a reduction in deferred compensation expense.



Interest income.Interest income was $376,000 for the three months ended March 31, 2005 compared to $149,000 for the three months ended March 31,
2004. The increase in interest income was primarily attributable to higher cash balances and a better rate of return for the three months ended March 31, 2005 compared to the three months ended March 31, 2004 primarily as a result of our receipt of
$52.8 million of proceeds (net of underwriting discounts and offering expenses) in connection with our January 2005 financing.



Interest expense. Interest expense was $17,000 for the three months ended March 31, 2005 compared to $2,000 for the three months ended March 31,
2004. Interest expense incurred during the first quarter of 2005 was primarily attributable to the interest accrued on the $3.5 million liability due (and fully paid during the quarter) to Allergan as a result of our reacquisition of all rights to
market and sell Vitrase in the United States and other specified markets. The interest expense incurred during 2004 was primarily attributable to the interest paid on the financing of our directors and officers insurance premiums.



Liquidity and Capital Resources



As of March 31, 2005, we had approximately $67.1 million in cash and
equivalents and short-term investments and working capital of $63.9 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, $14.5 million from our registered direct offerings in August
2004 and $52.8 million from our follow-on public offering in January 2005. The private investment in public equity, or 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, before offering expenses and fees. 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, before offering expenses and underwriting discounts. In April 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. On August 6, 2004 we sold
1,570,000 shares of common stock under our universal shelf registration statement on Form S-3 for an aggregate purchase price of $13.3 million, or $8.50 per share, before placement agency fees and other offering expenses. On August 10, 2004, we sold
an additional 250,000 shares of common stock under our universal shelf registration statement for an aggregate purchase price of $2.1 million, or $8.50 per share, before offering expenses. In January 2005, we sold 6,325,000 shares of our common
stock under our universal shelf registration statement in an underwritten public offering for an aggregate purchase price of $56.2 million, or $8.88 per share, before offering expenses and underwriting discounts.



For the three months ended March 31, 2005, we used $13.7 million of cash for
operations principally as a result of the net loss of $8.2 million and the change in other liabilities of $3.6 million, including a $3.5 million payment (including interest) incurred as a result our reacquisition of all rights to market and sell
Vitrase in the United States and other specified markets from Allergan. For the three months ended March 31, 2004, we used approximately $5.8 million of cash for operations.



For the three months ended March 31, 2005, we used $23.4 million of cash from investing activities, primarily due to the
purchase of our short-term investment securities. For the three months ended March 31, 2004, we received $6.2 million of cash from investing activities, primarily due to the maturities of our short-term investment securities.

##### Table of Contents

For the three months ended March 31, 2005, we received $53.2 million from financing activities, primarily
as a result of the sale of an aggregate of 6,325,000 shares of common stock under our universal shelf registration statement in an underwritten public offering for an aggregate purchase price of $56.2 million, before offering expenses and
underwriting discounts. For the three months ended March 31, 2004, we received $40,000 from financing activities, primarily from the exercise of stock options and the issuance of common stock under our Employee Stock Purchase Plan.



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:



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



| |  |  | sales and marketing activities, and expansion of our commercial infrastructure, related to our approved products and product candidates;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the results of our clinical trials and requirements to conduct additional clinical trials;
| | - |  | ------------------------------------------------------------------------------------------



| |  |  | the rate of progress of our research and development programs;
| | - |  | --------------------------------------------------------------



| |  |  | the time and expense necessary to obtain regulatory approvals;
| | - |  | --------------------------------------------------------------



| |  |  | activities and payments in connection with potential acquisitions of companies, products or technology;
| | - |  | -------------------------------------------------------------------------------------------------------



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



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

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 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 three of our product candidates have received regulatory approval from the FDA. In May 2004, the FDA approved our NDA for Vitrase, in a lyophilized
6,200 USP units multi-purpose vial, for use as a spreading agent. In December 2004, the FDA approved our supplemental NDA for Vitrase for use as a spreading agent at a concentration of 200 USP units/mL in sterile solution. In June 2004, we received
FDA approval of the NDA for Istalol for the treatment of glaucoma. In March 2005, we received FDA approval of the NDA for Xibrom for the treatment of ocular inflammation following cataract surgery. Approval from the FDA is necessary to manufacture
and market pharmaceutical products in the United States.



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 one NDA which is currently pending before the FDA for Vitrase for the treatment of vitreous hemorrhage.



We have an NDA currently pending before the FDA for Vitrase for the treatment
of vitreous hemorrhage. 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.



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. We have filed Investigation New Drug Applications, or INDs, with the FDA in March
and April 2005, respectively, to conduct a U.S. Phase IIb study of ecabet sodium for the treatment of dry eye syndrome and to conduct a U.S. Phase III study of our proprietary formulation of a fixed combination product of tobramycin and prednisolone
acetate (the tobra/pred product) for the treatment of steroid-responsive inflammatory ocular conditions where risk of bacterial infection exists. We expect to initiate our ecabet sodium Phase IIb study in the second half of 2005 and our
tobra/pred product Phase III study in the third quarter of 2005. However, we can provide no assurance as to whether the results of these studies, if initiated, will be successful.



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;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

##### Table of Contents

| |  |  | 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 clinical testing and 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, pursuant to our collaborations, certain of our products, and perhaps have certain of our products or raw materials manufactured, in foreign countries. Many other countries, including major European
countries and Japan, have similar requirements as the United States for the manufacture, marketing and sale of pharmaceutical products. In addition, the process of obtaining approvals in foreign countries is subject to delay and failure for similar
reasons.



If our products 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 is 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 our products.



We are
continuing to develop and enhance our sales, marketing and distribution capabilities. Although we have recently expanded our capabilities, our current resources in these areas are limited. In order to commercialize any products successfully, we must
continue to develop and expand substantial sales, marketing and distribution capabilities, and/or maintain our arrangements with Ventiv and Cardinal 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 63 as of December 31, 2004 to 127 as of March 31, 2005. We plan to expand our sales force from 50 sales representatives as of March 31,
2005 to approximately 70 sales representatives by the end of the first half of 2005 in conjunction with our expected commercial launch of Xibrom, for the treatment of ocular inflammation following cataract surgery. To execute our anticipated growth
successfully, we must attract and retain qualified personnel and manage and train 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 generated minimal 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 generated minimal revenue from product sales to date, and we may
never generate significant revenues from product sales in the future. In addition, we have never been profitable, and we might never become profitable. As of March 31, 2005, our accumulated deficit was $196.3 million, including a net loss of
approximately $8.2 million for the three months ended March 31, 2005. As of March 31, 2005, we had approximately $67.1 million in cash and cash equivalents and short-term investments and working capital of $63.9 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 continue to expand our commercial infrastructure in connection with our commercialization of 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. If we fail to obtain additional capital as and when required such failure could have a material adverse impact on our operating plan and business.



If actual future payments for allowances, discounts, returns, rebates and chargebacks exceed the estimates we made at the time of the
sale of our products, our financial position, results of operations and cash flows may be materially and negatively impacted.



We recognize product revenue net of estimated allowances for discounts, returns, rebates and chargebacks. Such estimates require our most subjective and
complex judgment due to the need to make estimates about matters that are inherently uncertain. Based on industry practice, pharmaceutical companies, including us, have liberal return policies. Generally, we are obligated to accept from customers
the return of pharmaceuticals that have reached their expiration date. We authorize returns for damaged products and exchanges for expired products in accordance with our return goods policy and procedures. In addition, like our competitors, we also
give credits for chargebacks to wholesale customers that have contracts with us for their sales to hospitals, group purchasing organizations, pharmacies or other retail customers. A chargeback is the difference between the price the wholesale
customer pays and the price that the wholesale customers end-customer pays for a product. Actual results may differ significantly from our estimated allowances for discounts, returns, rebates and chargebacks. Changes in estimates and
assumptions based upon actual results may have a material impact on our results of operations and/or financial condition. In addition, our financial position, results of operations and cash flows may be materially and negatively impacted if actual
future payments for allowances, discounts, returns, rebates and chargebacks exceed the estimates we made at the time of the sale of our products.



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



Our ability to execute our strategic plan is dependent upon our ability to
gain additional regulatory approvals for our product candidates and market acceptance for our approved products, expand our 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.



19

##### Table of Contents

We have limited sales, marketing and distribution capabilities to support the marketing of any products,
and we do not have significant 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 ecabet sodium
from Senju, and we have obtained a license for worldwide rights to Caprogel from the Eastern Virginia Medical School. We are responsible for the development of ecabet sodium 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 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 have entered into a master services agreement with
R.P. Scherer West, Inc., which was subsequently acquired by and remains a wholly owned subsidiary of Cardinal Health, Inc., for the manufacture of commercial quantities of our Vitrase product in a lyophilized 6,200 USP units multi-purpose vial and a
supply agreement with Alliance Medical Products, Inc. for the manufacture of commercial quantities of our Vitrase product in 200 USP units/mL in sterile solution. We also have entered into a manufacturing services agreement with Bausch & Lomb
Incorporated for the manufacture of commercial quantities of Istalol and Xibrom. 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 of all of our
contract manufacturers must comply with current Good Manufacturing Practice, or GMP, 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, Alliance Medical Products,
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 to those products used in our clinical trials so that regulatory
authorities will approve them as a manufacturer, or that such facilities, once approved, will produce on a timely basis enough product to meet our sales demands, or that they will maintain their compliance and good standing with regulatory
authorities. Any such failures could delay or stop our efforts to develop our product candidates and commercialize our products.



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



We have entered into
collaborations with Senju relating to Istalol, Xibrom and ecabet sodium. We have also entered into collaborations with Allergan and Otsuka relating to the commercialization of Vitrase in specified markets outside the United States for ophthalmic
uses for the posterior region of the eye. In September 2004, we entered into a new agreement with Allergan, replacing our previous Vitrase collaboration, under which we reacquired all rights to market and sell Vitrase for all uses in the United
States and other specified markets. Allergan retains an option to commercialize Vitrase for the posterior segment of the eye in Europe upon approval. If Allergan exercises its option, we will be dependent upon Allergan for the commercialization of
Vitrase for such approved uses in Europe. If Allergan does not exercise its option, then such European rights will revert to ISTA, and we will pay Allergan a royalty on our European sales of Vitrase for use in the posterior segment of the eye. We
depend on Otsuka for obtaining regulatory approval of Vitrase for ophthalmic uses for the posterior region of the eye 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 our partners 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 within the scope of these collaborations, or, in the case of Allergan and Otsuka, 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 or choose not to exercise their options, on relatively short notice, or pursue alternative technologies. Our agreements
with 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.



20

##### Table of Contents

Nonetheless, there can be no assurances that our collaborators will not develop competing products in different forms or products that compete indirectly
with our products.



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. For example, Biozyme Laboratories, Ltd. is currently our only source for
highly purified ovine hyaluronidase, which is the active ingredient in Vitrase. Our supply agreement with Biozyme ends in August 2007, after which any further supply of hyaluronidase by Biozyme to us would be subject to Biozymes agreement.
While we are currently pursuing additional sources for this material, our success in establishing such additional supply agreements cannot be assured. The active ingredient for Xibrom is also supplied to us from a sole supplier. We have also entered
into supply agreements with R.P. Scherer West and Alliance Medical Products to manufacture commercial quantities of Vitrase in a lyophilized 6,200 USP units multi-purpose vial and 200 USP units/mL in sterile solution, respectively. Currently, R.P.
Scherer West and Alliance Medical Products each is our sole source for Vitrase in these respective configurations. We also have supply agreements with Bausch & Lomb to manufacture commercial quantities of Istalol and Xibrom. Currently, Bausch
& Lomb is our sole source for Istalol and Xibrom.



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, for our approved products, could limit or stop commercial sales, which would have a material adverse effect on
our business and financial condition.



We depend on our Chief Executive
Officer, Vicente Anido, Jr., Ph.D., and other key personnel, to execute our strategic plan.



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 extensive government regulations to which we are subject is expensive and time consuming, and may result in the delay, cessation 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, or 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 and maintaining FDA and other governmental approvals in order to manufacture, market, sell and ship our products.
Consequently, there is always a risk that the FDA or other applicable governmental



21



---

##### Table of Contents

authorities will not approve our products, or will take post-approval action limiting, modifying or revoking our ability to manufacture or sell our products,
or that the rate, timing and cost of such approvals will adversely affect our product introduction plans or results of operations.



To the extent that our products are reimbursed by the Medicare, Medicaid and other federal programs, our marketing and sales activities will be subject to
regulation. Federal agencies in recent years have initiated investigations against and entered into multi-million dollar settlements with a number of pharmaceutical companies alleging violations of fraud and abuse provisions. We will need to ensure
that our sales force is properly trained to comply with these laws. Even with such training, there is a risk that some of our marketing practices could come under scrutiny, or that we will not be able to institute or continue certain marketing
practices.



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 of 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 54 U.S. and foreign
patents and 42 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 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 from the Eastern Virginia Medical School for Caprogel and from Senju for Istalol, Xibrom and ecabet
sodium. 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 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.



22



---

##### Table of Contents

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. Some of our 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.



In addition to protecting our own intellectual property rights, we may be required to defend against third parties who 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.



We have not conducted an extensive search of patents issued to other parties and no assurance can be given that such patents do not exist, haven not been
filed, or could not be issued which contain claims relating to our technology and products. If such patents do exist, the owners may bring claims against us for infringement, which might have an adverse effect on our business.



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.



Both governmental and private 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.



Sales of our products may continue to be adversely
affected by the continuing consolidation of our distribution network and the concentration of our customer base.



Our principal customers are wholesale drug distributors and major retail drug store chains. These customers comprise a significant part of the
distribution network for pharmaceutical products in the U.S. This distribution network is continuing to undergo significant consolidation marked by mergers and acquisitions among wholesale distributors and the growth of large retail drug store
chains. As a result, a small number of large wholesale distributors control a significant share of the market, and the number of independent drug stores and small drug store chains has decreased. We expect that consolidation of drug wholesalers and
retailers will increase pricing and other competitive pressures on drug manufacturers. We launched our first product, Istalol, in the third quarter of 2004 and our second product, Vitrase, in the first quarter of 2005. For the year ended December
31, 2004, our three largest customers accounted for 15%, 40% and 25%, respectively, of our net revenues. The loss of any of our customers could materially adversely affect our business, results of operations and financial condition and our cash
flows. In addition, none of our customers are party to any long-term supply agreements with us which would enable them to change suppliers freely should they wish to do so.



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. Such 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.



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. In addition, we face competition from manufacturers of generic drugs which may have an adverse impact on our product revenues.



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., Amphastar Pharmaceuticals, Inc., Bausch & Lomb, Halozyme Therapeutics,
Inc., Johnson & Johnson, Novartis AG, Pfizer, Inc., Eli Lilly and Company and Inspire Pharmaceuticals, Inc. 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. In the product first quarter of 2005, Alcon announced that it had filed an NDA for its product Nevanac (nepafenac), an anti-inflammatory
ophthalmic product and released data from its Phase III Nevanac clinical studies. If the NDA for this product is approved, it may be marketed as an alternative to and compete against Xibrom.



In addition, competition from generic drugs is a major challenge in the
United States to branded drug companies, like us, and may have a material adverse effect on our product revenues. In October 2004, the FDA granted Istalol a BT rating, which means that prescriptions for Istalol cannot be substituted
legally at pharmacies with generic timolol maleate products. Nonetheless, we believe that certain pharmacies may have substituted, and may be continuing to substitute, Istalol prescriptions with generic timolol maleate solutions. We have completed
an educational campaign to make our customers and pharmacies aware of Istalols BT rating and that Istalol cannot be substituted legally at pharmacies with generic timolol maleate products. In October 2004, the FDA informed us that Vitrase
(hyaluronidase for injection; lyophilized, ovine) for use as a spreading agent to facilitate the dispersion and absorption of other drugs was entitled to five-year new chemical entity market exclusivity pursuant to the federal Food, Drug and
Cosmetic Act. The FDA indicated that Vitrases new chemical entity exclusivity would bar submission to FDA of certain third party 505(b)(2) NDAs and Abbreviated New Drug Applications, or ANDAs, for drugs containing the same active moiety as
Vitrase. The submission bar would be for five years from Vitrases approval date (i.e., May 5, 2004) or for four years in the case of patent challenges. The FDA also said that Vitrases new chemical entity exclusivity is not a prohibition
on FDAs review and approval of any 505(b)(2) NDA or ANDA that was submitted to the agency before Vitrase was granted five-year exclusivity. In October 2004, the FDA approved Amphadase (hyaluronidase) injection, USP, 150 IU mL, a bovine-sourced
hyaluronidase, for use as a spreading agent. Amphadase, manufactured by Amphastar Pharmaceuticals, Inc., is the generic equivalent of a branded bovine-sourced hyaluronidase which is no longer commercially available. In March 2005, Halozyme
Therapeutics announced it had filed an NDA for Enhanze SC, a formulation of recombinant human hyaluronidase being developed as a spreading agent. If the NDA for this product is approved, it may be marketed as an alternative to and compete against
Vitrase. Our ability to secure the benefit of the Vitrase market exclusivity depends on a variety of factors, some of which are beyond our control, including, among others, the timing, content and outcome of actions and decisions by the FDA and
other regulatory authorities regarding third party products and the impact and scope of the Vitrase market exclusivity and its affect on third party products.



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 a commercial company, we have begun to market and promote our approved products, like Istalol and Vitrase, and 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



24

##### Table of Contents

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 affected November 2002. Our stock
price has been and may continue to be subject to significant volatility. The following factors 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, sale, and distribution of our
approved 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;
| | - |  | ----------------------------------------------------



| |  |  | future sales of debt or equity securities by us;
| | - |  | ------------------------------------------------



| |  |  | sales of our securities by our directors, officers or significant shareholders;
| | - |  | -------------------------------------------------------------------------------



| |  |  | 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 March 31, 2005 was approximately 82,785 shares and the average daily number of transactions was approximately 265 for the same period. If



25

##### Table of Contents

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, our follow-on public offering in November 2003, our registered direct offerings in August 2004 and our follow-on public offering in January 2005, we issued approximately 23.7 million shares of
our common stock. The shares of common stock issued in connection with these transactions represent approximately 92% of our common stock outstanding as of May 5, 2005. 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 November 2003 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. In April 2004, we filed a universal shelf registration statement on Form S-3 with the SEC, which was declared effective in May 2004, providing for the offering from time to time of up to $75
million of our securities, which may consist of common stock, preferred stock, warrants, or debt securities. On August 6, 2004 we sold 1,570,000 shares of common stock under our shelf registration statement for an aggregate purchase price of $13.3
million, or $8.50 per share, before placement agency fees and other offering expenses. On August 10, 2004, we sold 250,000 shares of common stock under our shelf registration statement for an aggregate purchase price of $2.1 million, or $8.50 per
share, before offering expenses. In January 2005, we sold 6,325,000 shares of our common stock under our universal shelf registration statement in an underwritten public offering for an aggregate purchase price of $56.2 million, or $8.88 per share,
before offering expenses and underwriting discounts.



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
stockholders.



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 could enable certain shareholders to exert control over us and our significant corporate decisions.



As of May 5, 2005, our directors, officers, and principal stockholders
together control approximately 55% of our voting securities, a concentration of ownership that could delay or prevent a change in control. We are obligated to include a representative of Investor Growth Capital as a nominee for election to our board
of directors and Sprout Capital has the right to designate two such nominees. Our principal 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.
| | - |  | ------------------------------------------------------------------------



26

##### Table of Contents

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 our
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. Seeking to minimize this risk, we 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 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 March 31, 2005, we have not used derivative instruments or engaged in hedging activities.



We have operated primarily in the United States. 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.



|Item 4 | Disclosure Controls and Procedures
|------ | ----------------------------------



Evaluation of disclosure controls and procedures



Management of the Company, with the participation and under the supervision of the Chief Executive Officer and Chief Financial Officer has evaluated the
effectiveness of the Companys disclosure controls and procedures (as defined in Exchange Act Rule 13a-15(e)) as of the end of the period covered by this annual report. Based on this evaluation the Chief Executive Officer and Chief Financial
Officer have concluded that the Companys disclosure controls and procedures are effective as of the end of the period covered by this periodic SEC filing to provide reasonable assurance that material information required to be disclosed by the
Company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified by the Securities and Exchange Commissions rules and forms. A controls system, no matter
how well designed and operated, cannot provide absolute assurance that the objectives of the controls are met, and no evaluation of controls can provide absolute assurance that all controls and instances of fraud, if any, within a company have been
detected.



Changes in internal control over financial reporting



The Company has not made any significant changes to its
internal control over financial reporting (as defined in rule 13a-15(f) and 15d-15(f) under the Exchange Act) during the fiscal quarter ended March 31, 2005 that have materially affected, or are reasonably likely to materially affect, the
Companys internal control over financial reporting.
