PSIVIDA CORP. AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

1. Operations and Basis of Presentation

The accompanying condensed consolidated financial statements of pSivida Corp. and subsidiaries (the Company) for the three months ended September 30, 2010 and 2009 are unaudited. Certain
information in the footnote disclosures of these financial statements has been condensed or omitted in accordance with the rules and regulations of the Securities and Exchange Commission (the SEC). These financial statements should be
read in conjunction with the Companys audited consolidated financial statements and footnotes included in its Annual Report on Form 10-K for the fiscal year ended June 30, 2010. In the opinion of management, these statements have been
prepared on the same basis as the audited consolidated financial statements as of and for the year ended June 30, 2010, and include all adjustments that are necessary for the fair presentation of the Companys financial position, results
of operations and cash flows for the periods indicated. The preparation of financial statements in accordance with U.S. generally accepted accounting principles (GAAP) requires management to make assumptions and estimates that affect,
among other things, (i) reported amounts of assets and liabilities; (ii) disclosure of contingent assets and liabilities at the date of the consolidated financial statements; and (iii) reported amounts of revenues and expenses during
the reporting period. The results of operations for the three months ended September 30, 2010 are not necessarily indicative of the results that may be expected for the entire fiscal year or any future period.

The Company develops tiny, sustained release, drug delivery products that are administered by implantation, injection or insertion and
provide sustained release of drugs on a controlled and level basis for months or years. The Companys lead product candidate, Iluvien®, delivers fluocinolone acetonide (FA) for the treatment of diabetic macular edema
(DME), a leading cause of vision loss estimated to affect more than a million people in the United States alone, for which there is currently no drug therapy approved by the U.S. Food and Drug Administration (FDA). Iluvien is
licensed to Alimera Sciences, Inc. (Alimera), which is completing fully-recruited Phase III clinical trials. Based on 24-month data released in December 2009, Alimera filed a New Drug Application (NDA) with the FDA in June
2010 and was granted Priority Review of the NDA on August 30, 2010. Under Priority Review, Alimera could receive a response to the NDA from the FDA by the end of calendar year 2010. If approved, Alimera has indicated that it expects to
commercialize Iluvien as early as the first calendar quarter of 2011. The Company has also licensed certain of its drug delivery technologies to Alimera for the development of certain other ophthalmic products.

The Company has previously developed with partners two of the only three FDA-approved sustained release products to treat chronic
back-of-the-eye diseases: Retisert® for the treatment of posterior uveitis and Vitrasert® for the treatment of AIDS-related cytomegalovirus (CMV) retinitis. Both of these products and the technologies underlying them are licensed
to Bausch & Lomb Incorporated (Bausch & Lomb). The Company also has a worldwide collaborative research and license agreement with Pfizer, Inc. (Pfizer) under which Pfizer may develop additional ophthalmic
products using certain of the Companys technologies.

The Companys future operating results may vary from year to
year and quarter to quarter, and such variations could be significant. Future operating results are expected to depend upon the amounts of payments that may be received from, and revenue recognition associated with, its current and any potential
future collaboration arrangements and the clinical development costs and outcomes of its current and potential future product candidates. The Company anticipates that existing capital resources of $15.3 million at September 30, 2010 should
enable it to maintain its current and planned operations into at least calendar year 2012. The Companys ability to fund its planned operations internally beyond then may be substantially dependent upon the timing of FDA approval of Iluvien,
which would result in a $25 million milestone payment due from Alimera, and the successful commercialization of Iluvien by Alimera.

References to $ are to U.S. dollars and references to A$ are to Australian dollars.

Recently Adopted Accounting Pronouncements

In October 2009, the
Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2009-13, Multiple-Deliverable Revenue Arrangements  a consensus of the FASB Emerging Issues Task



7

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS(Continued)

(Unaudited)



Force. ASU 2009-13 updates the existing multiple-element revenue arrangements guidance currently included under ASC 605-25, which originated primarily from the guidance in EITF Issue No.
00-21, Revenue Arrangements with Multiple Deliverables. The update provides principles for allocation of consideration among multiple elements of revenue arrangements, allowing more flexibility in identifying and accounting for separate
deliverables under an arrangement. ASU 2009-13 introduces an estimated selling price method for valuing the elements of a bundled arrangement if vendor-specific objective evidence or third-party evidence of selling price is not available. In
addition, the update also significantly expands related disclosure requirements. ASU 2009-13 was effective for revenue arrangements entered into or materially modified in fiscal years beginning on or after July 1, 2010. Adoption of this
standard did not have any material impact on the Companys consolidated financial statements.

In April 2010, the FASB
issued ASU No. 2010-17, Revenue Recognition (Topic 605  Milestone Method of Revenue Recognition: a consensus of the FASB EITF) (ASU 2010-17). ASU 2010-17 amends ASC 605-28 and establishes a revenue recognition method
for contingent consideration that is payable on achievement of an uncertain future event, referred to as a milestone. The scope of the milestone method is limited to research and development agreements and is applicable to milestones in
multiple-deliverable arrangements involving research and development transactions. The guidance does not preclude the application of any other applicable revenue guidance. ASU 2010-17 was effective for financial statements issued for fiscal years
beginning on or after July 1, 2010. Adoption of this standard did not have any material impact on the Companys consolidated financial statements.

2. Stockholders Equity

Warrants to Purchase Common Shares

At September 30, 2010, the Company had 7,062,248 warrants outstanding denominated in $ with a weighted average
exercise price of $7.53 and a weighted average remaining life of approximately 1.4 years. At September 30, 2009, the Company had 7,162,248 warrants outstanding with a weighted average exercise price of $7.50. During the three months ended
September 30, 2010 and 2009, there were no warrants granted or exercised.

At September 30, 2010 and 2009, the
Company had 3,935,433 warrants outstanding denominated in A$ with a weighted average exercise price of A$9.54. The weighted average exercise price of these warrants translated to $ was $9.25 at September 30, 2010 and $8.33 at September 30,
2009. At September 30, 2010, these outstanding warrants had a weighted average remaining life of approximately 5.5 months. During the three months ended September 30, 2010 and 2009, there were no warrants granted or exercised.

Because the potential exercise of the A$-denominated warrants would result in a variable amount of proceeds in the Companys
functional currency, the fair value of the warrants was recorded as a derivative liability, with a corresponding reduction in additional paid-in capital, subject to revaluation of the liability on a recurring basis through the statement of
operations. The fair value of the warrants is determined using a Black-Scholes model. The net change in the fair values of these derivative liabilities resulted in income of $338,000 and expense of $1.5 million for the three months ended
September 30, 2010 and 2009, respectively. The change in the fair value of these derivative liabilities is primarily attributable to the spread between the Companys share price and the US$-equivalent exercise prices of the underlying
warrants, and secondarily to the reduction of the remaining contractual life of the warrants.

3. License and Collaboration Agreements

Alimera Sciences, Inc.

Under a collaboration agreement with Alimera, as amended in March 2008 (the Alimera Agreement), the Company licensed Alimera the rights to develop, market and sell certain products, including
Iluvien. Alimera is completing fully-recruited Phase III trials for Iluvien in DME. Based on 24-month data released in December 2009, Alimera filed an NDA with the FDA in June 2010 and was granted Priority Review of the NDA on August 30, 2010.
Under Priority Review, Alimera could receive a response to the NDA from the FDA by the end of calendar year 2010.

Upon
execution of the Alimera Agreement in March 2008, the Company received consideration of $12.0 million in cash and Alimera cancelled $5.7 million of accrued development cost liabilities, including related

(Unaudited)



penalties and accrued interest, owed by the Company to Alimera as of March 14, 2008. In addition, the Company received a $15.0 million conditional note providing for aggregate principal and
interest payments of up to approximately $21.3 million through September 2012, Alimera agreed to pay a $25.0 million milestone payment upon FDA approval of Iluvien, and Alimera assumed all financial responsibility for the development of licensed
products under the Alimera Agreement, which had previously been shared equally, including reimbursement of approved development costs incurred by the Company in support of the ongoing clinical studies of Iluvien and anticipated regulatory
submissions. In exchange, the Company decreased its share in any future profits, as defined, on sales of Iluvien by Alimera from 50% to 20%, subject to an offset of 20% of pre-profitability commercialization costs, as defined, incurred by Alimera.
In the event Alimera sublicenses commercialization, the Company is entitled to receive 20% of royalties and 33% of non-royalty consideration received by Alimera, less certain permitted deductions. On April 27, 2010, Alimera paid the $15.0
million conditional note in full together with $225,000 of accrued and unpaid interest.

The initial $18.3 million of deferred
revenue was recognized as revenue on a straight-line basis over the 21.5 month performance period from the effective date of the Alimera Agreement through December 31, 2009. All additional cash consideration received from Alimera during the
performance period, which consisted of conditional note payments and development cost reimbursements, was recognized as revenue during the performance period using the cumulative catch-up method.

Revenue related to the Alimera Agreement totaled approximately $54,000 and $3.2 million during the three months ended September 3,
2010 and 2009, respectively. These revenues represented the primary component of the Companys collaborative research and development revenue for these periods.

Pfizer

In April 2007, the Company and Pfizer entered into a
worldwide collaborative research and license agreement (the Pfizer Agreement), which superseded a December 2006 research agreement. Under the Pfizer Agreement, the parties have implemented a joint research program aimed at developing
certain ophthalmic products that are not licensed to others using the Companys technologies. In addition to potential development and sales related milestone payments, Pfizer pays the Company a minimum of $500,000 quarterly in consideration of
the Companys costs in performing the research program. These payments commenced in calendar year 2008 and continue until the earlier of the commencement of the first Phase III clinical trial for a licensed product candidate or the termination
of the Pfizer Agreement.

Following an evaluation of the multiple deliverables, the Company determined that the Pfizer
Agreement and the preceding Pfizer research agreement should be combined for accounting purposes as a single unit of accounting. The Company is unable to define the time period of its overall deliverables and other obligations under the Pfizer
Agreement and, as a result, all payments received or receivable from Pfizer through September 30, 2010, totaling $6.25 million, were classified in non-current deferred revenue. Accounts receivable from Pfizer totaled $500,000 and $0 at
September 30, 2010 and June 30, 2010, respectively.

Intrinsiq

In January 2008, the Company and Intrinsiq Materials Cayman Limited (Intrinsiq) entered into an agreement pursuant to which
Intrinsiq acquired an exclusive field-of-use license to develop and commercialize nutraceutical and food science applications of BioSilicon, and certain related assets, for $1.2 million. Provided the license agreement remains in effect, Intrinsiq is
obligated to pay the Company aggregate minimum royalties of $3.55 million through April 2014, of which the first $450,000 was paid in July 2009.

Under the original agreement, the parties were obligated to enter into a manufacture and supply agreement, which was consummated effective as of February 1, 2009. Pursuant to the supply agreement,
the Company leased to Intrinsiq certain equipment for its use in manufacturing BioSilicon material. Subject to its right to terminate the lease, Intrinsiq will acquire title to the equipment upon the remittance of lease payments totaling $122,000
over the 2-year lease term, of which the first three payments of $24,000 each were received through September 2010.

The
Company determined that the equipment lease component represented a separate element of this arrangement. Using the relative fair value method prescribed under the authoritative guidance, the Company allocated the arrangement consideration between
the lease and license deliverables. The Company determined the performance period of the license arrangement to be 17 years, coinciding with the last to expire of the patents licensed to Intrinsiq, and is recognizing consideration allocated to the
license arrangement on a straight-line basis over this period. The Company recognized collaborative research and development revenue of $20,000 and $60,000

for the three months ended September 30, 2010 and 2009, respectively, and the remaining balance of payments received, including minimum royalties, of approximately $1.2 million was recorded
as deferred revenue at September 30, 2010.

Bausch & Lomb

The Companys Retisert and Vitrasert products were developed and commercialized under a 1992 licensing and development agreement with
Bausch & Lomb. Pursuant to a subsequent collaboration agreement, Bausch & Lomb has a worldwide exclusive license to make and sell Vitrasert and our first-generation products (as defined in the agreement, including the Retisert
device) in return for royalties based on sales.

In June 2005, the Company received a $3.0 million advance from
Bausch & Lomb in consideration of $6.25 million of future Retisert royalties that otherwise would be payable to the Company. During the quarter ended June 30, 2010, Bausch & Lomb retained the final portion of these royalties
otherwise payable under the advance royalty agreement. Accounts receivable from Bausch & Lomb totaled $373,000 and $342,000 at September 30, 2010 and June 30, 2010, respectively.

estimated useful lives. Amortization of intangible assets totaled $811,000 and $844,000 for the three months ended September 30, 2010 and 2009, respectively. The carrying value of intangible assets at September 30, 2010 of $23.8 million
will be amortized on a straight-line basis over the remaining estimated useful life of 7.25 years, or approximately $3.3 million per year. Of the total net book value at September 30, 2010, approximately $7.6 million was attributable to the
Companys Durasert technology and $16.2 million was attributable to its BioSilicon technology.

During the three months ended September 30, 2010, approximately $3.5 million of marketable securities
were purchased and $300,000 matured. At September 30, 2010, the marketable securities had maturities ranging between three and ten months, with a weighted average maturity of 6.7 months.

6. Fair Value Measurements

The Company accounts for certain assets and
liabilities at fair value. The hierarchy below lists three levels of fair value based on the extent to which inputs used in measuring fair value are observable in the market. The Company categorizes each of its fair value measurements in one of
these three levels based on the lowest level input that is significant to the fair value measurement in its entirety. These levels are:



| |  |  | Level 1  Inputs are quoted prices in active markets that are accessible at the measurement date for identical assets and liabilities. The fair
value hierarchy gives the highest priority to Level 1 inputs.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Level 2  Inputs are observable prices that are not quoted on active markets, but corroborated by market data.
| | - |  | --------------------------------------------------------------------------------------------------------------



| |  |  | Level 3  Inputs are unobservable estimates that are supported by little or no market activity and require the Company to develop its own
assumptions about how market participants would price the assets or liabilities. The fair value hierarchy gives the lowest priority to Level 3 inputs.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of cash, cash equivalents and marketable securities. At September 30, 2010 and June 30,
2010, substantially all of the Companys interest-bearing cash equivalent balances were concentrated in two institutional money market funds that have investments consisting primarily of certificates of deposit, commercial paper, time deposits,
U,S. government agencies, treasury bills and treasury repurchase agreements. Generally, these deposits may be redeemed upon demand and, therefore, bear minimal risk.

The Companys marketable securities are classified within Level 1 (corporate bonds) or Level 2 (U.S. government obligations and commercial paper) on the basis of valuations using quoted market price
or alternative pricing sources and models utilizing market observable inputs, respectively. The Companys derivative liabilities are classified as Level 3 and valued using the Black-Scholes model.

The Companys derivative liabilities were classified as Level 3 and valued using the Black-Scholes
model. At September 30, 2010 and June 30, 2010, the fair values were derived by applying the following assumptions:



|                         |  |                    |  |

|Expected term (in years) |  | 0.25 - 1.79        |  | 0.5 - 2.04   
|Stock volatility         |  | 95%                |  | 95%          
|Risk-free interest rate  |  | 0.16% - 0.39%      |  | 0.22% - 0.63%
|Expected dividends       |  | 0%                 |  | 0%           

The
reconciliation of the Companys liabilities measured at fair value on a recurring basis using unobservable inputs (Level 3) is as follows:

7. Stock-Based Compensation

As of September 30, 2010, the Company had two shareholder-approved stock-based compensation plans: the 2008 Incentive
Plan, as amended on November 19, 2009 (the 2008 Plan), and the Employee Share Option Plan (the Plan).

2008 Incentive Plan

The 2008 Plan provides for the issuance of a
maximum of 3,491,255 shares of common stock in satisfaction of stock-based awards to directors, executives, employees and consultants.

The following table provides a reconciliation of stock option activity under the 2008 Plan for the three months ended September 30, 2010:

The exercise
prices of all outstanding options under the Plan at September 30, 2010 were in excess of the market price of the Companys common shares at that date, and, accordingly, the options had no aggregate intrinsic value. No options vested during
the three months ended September 30, 2010.

the Plan for the three months ended September 30, 2010:

At September 30, 2010, there was approximately $1.9 million of unrecognized compensation expense
related to unvested share-based payment awards under the Companys option plans, which is expected to be recognized as expense over a weighted average period of 2.0 years.

8. Income Taxes

The Company recognizes deferred tax assets and liabilities
for estimated future tax consequences of events that have been recognized in the financial statements or tax returns. Under this method, deferred tax assets and liabilities are determined based on the difference between the financial statement and
tax basis of assets and liabilities using the enacted tax rates in effect for the year in which the differences are expected to reverse. A valuation allowance is established if, based on managements review of both positive and negative
evidence, it is more likely than not that all or a portion of the deferred tax assets will not be realized. Because of its historical losses from operations, the Company established a valuation allowance for the net deferred tax assets. During the
three months ended September 30, 2010, the Company recorded income tax expense of $9,000, primarily related to estimated U.S. federal income taxes for fiscal 2011, net of earned foreign research and development tax credits.

(Unaudited)



For the three months ended September 30, 2010 and 2009, the Company had no
significant unrecognized tax benefits in the accompanying unaudited condensed consolidated financial statements. As of September 30, 2010 and June 30, 2010, the Company had no accrued penalties or interest related to uncertain tax
positions.

9. Loss Per Share

Basic net loss per share was computed by dividing the net loss by the weighted average number of common shares outstanding during the period. Diluted net loss per share was computed by dividing the net
loss by the sum of (i) the weighted average number of common shares outstanding and (ii) the weighted average number of common shares that would be issued on the conversion of all dilutive securities outstanding. Potentially dilutive
shares were not included in the calculation of diluted net loss per share for each of the three months ended September 30, 2010 and 2009 as their inclusion would be anti-dilutive.

Potentially dilutive shares at September 30, 2010 and 2009 were as follows:



|         |  |               |            |  |      |  |            |

11. Subsequent Event

In October 2010, the Company exercised an option to renew the lease of its Watertown, Massachusetts facility for three years through April 2014 on terms substantially equivalent to the current lease. The
Company has evaluated subsequent events from September 30, 2010 through the date of the issuance of these financial statements and has determined that no material subsequent events have occurred that would affect the information presented in these
financial statements or require additional disclosure.

Note Regarding Forward-Looking Statements

Various statements made in this Quarterly Report on Form 10-Q are forward-looking and involve risks and uncertainties. All statements that address activities, events or developments that we intend, expect
or believe may occur in the future are forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended (Securities Act), and Section 21E of the Securities Exchange Act of 1934, as amended (Exchange
Act). Such statements give our current expectations or forecasts of future events; they do not relate strictly to historical or current facts. All statements other than statements of current or historical facts are forward-looking statements,
including, without limitation, any expectations of revenues, expenses, cash flows, earnings or losses from operations, capital or other financial items; any statements of the plans, strategies and objectives of management for future operations; any
statements concerning product research, development and commercialization timelines; any statements of expectations or belief; and any statements of assumptions underlying any of the foregoing. We often, although not always, identify forward-looking
statements by using words or phrases such as likely, expect, intend, anticipate, believe, estimate, plan, project, forecast and
outlook.

The following are some of the factors that could cause actual results to differ materially from the
anticipated results or other expectations expressed, anticipated or implied in our forward-looking statements: Alimeras ability to obtain regulatory approval of and successfully commercialize Iluvien; risk/benefit profile of Iluvien;
timeliness of approval, if any, of Iluvien and any limitations on uses thereof; ability to complete clinical trials and obtain regulatory approval of other product candidates; ability to raise capital; ability to achieve profitability; impairment of
intangibles; fluctuations in the fair values of certain outstanding warrants; fluctuations in operating results; ability to derive revenues from Retisert; ability to obtain partners to develop and market products; termination of license agreements;
competition; market acceptance of products and product candidates; reduction in use of products as a result of future publications; ability to protect intellectual property or infringement of others intellectual property; retention of key
personnel; product liability; consolidation in the pharmaceutical and biotechnology industries; compliance with environmental laws; manufacturing risks; risks and costs of international business operations; credit and financial market conditions;
legislative or regulatory changes; volatility of stock price; possible dilution through exercise of outstanding warrants and stock options or future stock issuances; possible influence by Pfizer; ability to pay any registration penalties; absence of
dividends; and other factors described in our filings with the Securities and Exchange Commission. You should read and interpret any forward-looking statements together with these risks. Should known or unknown risks materialize, or should
underlying assumptions prove inaccurate, actual results could differ materially from past results and those anticipated, estimated or projected in the forward-looking statements. You should bear this in mind as you consider any forward-looking
statements.

Our forward-looking statements speak only as of the date on which they are made. We do not undertake any
obligation to publicly update or revise our forward-looking statements even if experience or future changes makes it clear that any projected results expressed or implied in such statements will not be realized.

Our Business

We develop tiny, sustained release, drug delivery products that are administered by implantation, injection or insertion. Once administered, a drug is released on a controlled and level basis for months
or years. We have two core technology systems, Durasert and BioSilicon. Utilizing three generations of our Durasert technology system, we have one product candidate for chronic eye disease that has been given Priority Review by the U.S.
Food and Drug Administration (FDA) and two of the only three products approved by the FDA for the long-term, sustained release delivery of drug to treat chronic eye disease. We have a collaboration agreement with Pfizer, our largest shareholder, to
develop additional ophthalmic products.

Iluvien®, the product candidate with Priority Review, is designed to provide
sustained release treatment for Diabetic Macular Edema (DME). DME is a leading cause of vision loss for people under the age of 65 and has been estimated to affect over 1,000,000 people in the United States. Using the third generation of our
Durasert technology system, Iluvien is injected into the eye and delivers the corticosteroid fluocinolone acetonide (FA) over a period of up to 3 years.

Iluvien is licensed to Alimera, which is completing fully-recruited Phase III clinical trials. Based on 24-month data released in December 2009, Alimera filed a New Drug Application (NDA) with the FDA in
June 2010 and registration filings in various European countries in July 2010. On August 30, 2010, the FDA granted Priority

Review status and, as a result, Alimera could receive a response to its NDA from the FDA by the end of calendar year 2010. If approved, Alimera has indicated that it expects to commercialize
Iluvien as early as the first calendar quarter of 2011. Under our collaboration agreement with Alimera, Iluvien is also being studied in investigator-sponsored pilot clinical trials designed to assess the safety and efficacy of Iluvien in both wet
and dry Age-Related Macular Degeneration (AMD) and Retinal Vein Occlusion (RVO).

Our two FDA-approved products utilize
earlier generations of our Durasert technology system, second-generation Retisert® for the treatment of posterior uveitis, and first-generation Vitrasert® for the treatment of AIDS-related cytomegalovirus retinitis. We have licensed both of
these products and the technologies underlying them to Bausch & Lomb. Retisert provides sustained release treatment for approximately two and a half years, and Vitrasert provides sustained release treatment for six to nine months.

Under our worldwide collaborative research and license agreement with Pfizer, we are working together on a joint research
program aimed at developing certain ophthalmic applications of our sustained drug delivery technologies not licensed to others.

BioSilicon, our other principal technology system, is a fully-erodible, nanostructured, porous silicon designed to provide sustained
delivery of various therapeutics, including small drug molecules, proteins and peptides. Based on results of our preliminary studies, we are currently targeting BioSilicon as a second key prong of our drug delivery technology platform.

Medidur, Durasert and BioSilicon are our trademarks. Retisert® and Vitrasert® are Bausch & Lombs
trademarks, and Iluvien® is Alimeras trademark.

Critical Accounting Policies and Estimates

The preparation of consolidated financial statements in conformity with GAAP requires that we make certain estimates,
judgments and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses. We base our estimates, judgments and assumptions on historical experience, anticipated results and trends, and on various other factors that we
believe are reasonable under the circumstances at the time. By their nature, these estimates, judgments and assumptions are subject to an inherent degree of uncertainty. Actual results may differ from our estimates under different assumptions or
conditions. In our Annual Report on Form 10-K for the year ended June 30, 2010, we set forth our critical accounting policies and estimates, which included revenue recognition and the carrying value of our intangible assets. There have been no
material changes to our critical accounting policies from the information provided in our 2010 Annual Report on Form 10-K as filed with the SEC.

Revenues

Revenues decreased by approximately $2.9 million, or 86%, to $476,000 for the three months ended September 30, 2010 from approximately $3.4 million for the three months ended September 30, 2009.
On December 31, 2009, we completed the 21.5 month performance obligation period during which we amortized to revenues the consideration received from Alimera in connection with our 2008 amended collaboration agreement. Collaborative research
and development revenue related to our Alimera collaboration agreement totaled $54,000 and approximately $3.2 million for the three months ended September 30, 2010 and 2009, respectively.

We would be entitled to receive a $25.0 million milestone payment from Alimera within 30 days following FDA approval of Iluvien. Absent
FDA approval of Iluvien during fiscal year 2011, we currently expect to record an insignificant amount of collaborative research and development revenue attributable to the Alimera collaboration agreement in fiscal year 2011.

Pursuant to a June 2005 side letter to the collaboration agreement with Bausch & Lomb, we received $3.0 million from
Bausch & Lomb as an advance payment in lieu of $6.25 million of future Retisert royalties that otherwise would have been payable to us. The advance royalty was completed as of June 30, 2010. Royalty income from sales of Retisert for
the three months ended September 30, 2010 totaled $373,000 compared to $374,000 of royalties that would otherwise have been payable for the three months ended September 30, 2009.

Research and Development

Research and development decreased by $58,000, or 3%, to approximately $1.7 million for the three months ended September 30, 2010 from $1.8 million for the three months ended September 30, 2009.
This decrease was primarily attributable to the absence in the current period of $140,000 of third-party costs of our BrachySil clinical program in the prior year period, partially offset by increased costs of pre-clinical studies and related
supplies.

General and
Administrative

General and administrative increased by $479,000, or 28%, to approximately $2.2 million for the three
months ended September 30, 2010 from approximately $1.7 million for the three months ended September 30, 2009. This increase was primarily attributable to increased professional fees and stock-based compensation.

Change in Fair Value of Derivatives

Change in fair value of derivatives represented income of $338,000 for the three months ended September 30, 2010 compared to expense of approximately $1.5 million for the three months ended
September 30, 2009. This net change was due to the increased spread between the US$-equivalent weighted average exercise price of the A$-denominated warrants during the current period compared to a corresponding decrease in the spread for the
prior year period and the short remaining life of these warrants (weighted average of 5.5 months at September 30, 2010).

Utilizing the Black-Scholes valuation model, we record the fair value of detachable warrants issued in connection with prior years
share offerings denominated in A$ as a derivative liability at each balance sheet date, and changes in their fair values result in corresponding income or expense in our statement of operations for those periods. Fluctuations in the fair values of
these warrants, which could be substantial, particularly given their short remaining life, will continue to affect our operating results until the last-to-expire of these warrants in July 2012.

Interest Income

Interest income of $6,000 for the three months ended September 30, 2010 compared to $2,000 for the three months ended September 30, 2009. This increase was attributable to a combination of
higher average interest-bearing balances and marginally higher interest rates on investments in marketable securities during the three months ended September 30, 2010.

Income Tax (Expense) Benefit

Income tax expense of $9,000 for the
three months ended September 30, 2010 compared to an income tax benefit of $24,000 for the three months ended September 30, 2009. The net change was primarily attributable to a $21,000 increase in U.S. federal alternative minimum tax expense
and an $11,000 decrease of foreign research and development tax credits earned by our U.K. subsidiary.

Liquidity and
Capital Resources

During the past three fiscal years, we have financed our operations primarily from license fees,
research and development funding and contingent cash payments from our collaboration partners and, to a lesser degree, from a July 2007 private placement of our equity securities. At September 30, 2010, our principal sources of liquidity
consisted of cash, cash equivalents and marketable securities totaling approximately $15.3 million. Our cash equivalents are invested in institutional money market funds and our marketable securities are invested in investment-grade corporate debt,
government agency securities and commercial paper with maturities at September 30, 2010 ranging from 3 to 10 months.

With the exception of fiscal year 2010, we have incurred operating losses each year since inception and, at September 30, 2010, we
had a total accumulated deficit of $221.4 million. We generally expect negative cash flows from operations on a quarterly basis at least until such time as one or more of our product candidates achieve regulatory approval and sufficient revenues. We
believe we can fund our operations as currently conducted into at least calendar year 2012. Whether we will require, or desire, to raise additional capital will be influenced by many other factors, including, but not limited to:



| |  |  | the continuation of our collaborations with Pfizer and Alimera, including their continued funding of our programs and our receipt of applicable
milestone, royalty and other payments;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the timing of FDA regulatory approval and commercialization of Iluvien;
| | - |  | -----------------------------------------------------------------------



| |  |  | the amount of quarterly royalty payments from sales of Retisert;
| | - |  | ----------------------------------------------------------------



| |  |  | the scope and extent of our internally funded existing operations and programs, any new product candidates and any new business opportunities;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------

| |  |  | our ability to establish and maintain strategic arrangements for product candidates for research, development, clinical testing, manufacturing and
marketing;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the success of our products and product candidates, including the timing and costs of regulatory approvals and the commercial success of approved
products;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the costs involved in preparing, filing, prosecuting, maintaining, defending and enforcing patent claims; and
| | - |  | -------------------------------------------------------------------------------------------------------------



| |  |  | changes in our operating plan, including the pursuit of new business opportunities, which may affect our need for capital.
| | - |  | --------------------------------------------------------------------------------------------------------------------------

Absent adequate levels of funding from new and existing collaboration agreements and/or financing
transactions, management currently believes that our cash position thereafter will be substantially dependent upon the timing of FDA approval and the initiation and success of commercialization of Iluvien, and the resulting occurrence of certain
milestone events under the terms of our collaboration agreement with Alimera. Alimera has agreed to pay us $25.0 million upon FDA approval of Iluvien for DME and a 20% profit share on its sales of Iluvien, subject to offset of 20% of defined
pre-profitability commercialization costs incurred by Alimera. In the event Alimera sublicenses commercialization, we would receive 20% of royalties and 33% of non-royalty consideration received by Alimera, less certain permitted deductions. There
is no assurance that the FDA will approve Iluvien, or that Iluvien will achieve market acceptance even if it is approved by the FDA.

The downturn in the economy and the disruptions in the financial and credit markets have made it significantly more difficult and more expensive to obtain financing. If we determine that it is desirable
or necessary to raise additional capital in the future, we do not know if it will be available when needed or on terms favorable to us or our stockholders. If available, additional equity financing may be dilutive to stockholders, debt financing may
involve restrictive covenants or other unfavorable terms and potential dilutive equity, and funding through collaboration agreements may be on unfavorable terms, including requiring us to relinquish rights to certain of our technologies or products.
If adequate financing is not available if and when needed, we may be required to delay, reduce the scope of or eliminate one or more of our research or development programs, postpone the pursuit of product candidates and new business opportunities,
or otherwise reduce our cash requirements.

Our consolidated statements of cash flows are summarized as follows:

Net cash used in operating activities increased by approximately $1.3 million to $2.2 million for the three
months ended September 30, 2010 compared to $925,000 for the three months ended September 30, 2009. The net increase of cash used in operating activities consisted of a $970,000 decrease of collaborative research and development and
royalty cash inflows and a net $325,000 increase in operating cash outflows.

Net cash used in investing activities consisted
predominantly of approximately $3.5 million of purchases and $300,000 of maturities of marketable securities during the three months ended September 30, 2010. There was no cash used in investing activities for the three months ended
September 30, 2009.

We had no borrowings or line of credit facilities as of September 30, 2010.

Off-Balance
Sheet Arrangements

We had no off-balance sheet arrangements as of September 30, 2010 that have, or are reasonably
likely to have, a current or future effect on our financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources that would be material to investors.



|Item 3. | Quantitative and Qualitative Disclosures About Market Risk
|------- | ----------------------------------------------------------

We have exposure to changes in the valuation of derivative liabilities, foreign currency exchange rates and interest rates.

Derivative Liabilities

At September 30, 2010, the balance of
our derivative liabilities, which relate to warrants denominated in A$, totaled $972,000 and was determined using the Black-Scholes valuation model. The change in fair value of derivatives resulted in income of $338,000 and expense of approximately
$1.5 million for the three months ended September 30, 2010 and 2009, respectively.

Our financial position and results of
operations will continue to be sensitive to future revaluations of these derivative liabilities. At September 30, 2010, these warrants had a weighted average remaining contractual life of approximately 5.5 months and a weighted average exercise
price of $9.25 per share compared to the $4.38 NASDAQ closing price of our common shares. The primary factor that impacts the change in fair value of these derivatives is the change in the spread between our share price and the US$-equivalent
weighted average exercise price. Reduction of the remaining contractual life of the warrants, assuming that share price, volatility and A$ to US$ exchange rate remain constant, would result in a significant decrease of the derivative liability value
during the remainder of fiscal year 2011. Changes in risk-free interest rates have a de minimis effect.

The following
table summarizes the sensitivity of our consolidated statement of operations for the three months ended September 30, 2010 to assumed increases or decreases of our share price at September 30, 2010:



|                                                       |  |                         |     |  |              |   |     |                         |  |   |     |     |  |   |      |  |  |      |      |   |  |   |      |   |  |   |      |

Foreign Currency Exchange Rates

We conduct operations in two principal currencies, the U.S. dollar and the Pound Sterling (£). The U.S. dollar is the
functional currency for our U.S. operations, and the Pound Sterling is the functional currency for our U.K. operations. Changes in the foreign exchange rate of the U.S. dollar and Pound Sterling impact the net operating expenses of our
U.K. operations. For the three months ended September 30, 2010, the strengthening of the U.S. dollar compared to the comparable period of the prior year resulted in a net decrease in research and development expenses of approximately $50,000.
All cash and cash equivalents, and most other asset and liability balances, are denominated in each entitys functional currency and, accordingly, we do not consider our statement of operations exposure to realized and unrealized foreign
currency gains and losses to be significant.

Changes in the foreign exchange rate of the U.S. dollar and Pound Sterling
also impact total stockholders equity. At September 30, 2010, compared to June 30, 2010, the weakening of the U.S. dollar in relation to the Pound Sterling resulted in a net increase of approximately $720,000 in
stockholders equity due to the translation of approximately £9.5 million of net assets of our U.K. operations, predominantly the BioSilicon technology intangible asset, into U.S. dollars. For every incremental 5% strengthening or
weakening of the U.S. dollar at September 30, 2010 in relation to the Pound Sterling, our stockholders equity at September 30, 2010 would have decreased or increased, respectively, by approximately $750,000.

Interest Rates

Cash and cash equivalent balances are subject to variable interest rates. We do not consider our exposure to interest
rates to be significant.



|Item 4. | Controls and Procedures
|------- | -----------------------

Evaluation of Disclosure Controls and Procedures

We have established disclosure controls and procedures designed to ensure that material information relating to us, including our consolidated subsidiaries, is made known to the officers who certify our
financial reports and to other members of senior management and the Board of Directors.

Our management, with the
participation of our principal executive officer and principal financial officer, evaluated the effectiveness of our disclosure controls and procedures as of September 30, 2010. The term disclosure controls and procedures, as
defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, means controls and other procedures of a company that are designed to ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange
Act is recorded, processed, summarized and reported within the time periods specified in the SECs rules and forms and that such information is accumulated and communicated to our management, including our principal executive officer and
principal financial officer, as appropriate, to allow timely decisions regarding required disclosure, particularly during the period in which this Quarterly Report on Form 10-Q was being prepared. Management recognizes that any controls and
procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their desired objectives, and our management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls
and procedures. Based on the evaluation of our disclosure controls and procedures as of September 30, 2010, our principal executive officer and principal financial officer concluded that, as of such date, our disclosure controls and procedures
were effective at the reasonable assurance level.

Changes in Internal Control over Financial Reporting

During the period covered by this report, there have been no changes in our internal control over financial reporting
that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
