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 and nine months ended March 31, 2011 and 2010 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 and nine months ended March 31, 2011 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. Once
administered, a drug is released on a controlled and level basis for months or years. The Company has two core technology systems, Durasert and BioSilicon. Utilizing three generations of its Durasert technology system, the Company has
one product candidate for chronic eye disease for which a New Drug Application (NDA) has been filed with 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.

ILUVIEN®, the Companys lead product candidate
under FDA review, uses the third generation of the Durasert technology system to deliver the corticosteroid fluocinolone acetonide (FAc) over a period of up to 3 years for the treatment of Diabetic Macular Edema (DME).
ILUVIEN is licensed to Alimera Sciences, Inc. (Alimera). Based on analysis of 24-month data from Phase III trials, Alimera filed an NDA with the FDA in June 2010 and registration filings in various European countries in July 2010. After
granting Priority Review status, the FDA issued a Complete Response Letter (CRL) in December 2010, which communicated the FDAs decision that the NDA for ILUVIEN for DME could not be approved in its then present form. In the CRL,
the FDA requested analyses of safety and efficacy data through month 36, including exploratory analyses in addition to those analyses previously submitted in the NDA, to further assess the relative benefits and risks of ILUVIEN, as well as other
information. On February 3, 2011, Alimera reported 36-month safety and efficacy data from the completed trials, which Alimera stated it would submit to the FDA as part of the pending NDA. On May 3, 2011, 36-month data for the subgroup of
patients who had been diagnosed with DME for three or more years at entry of the trials was reported. Alimera stated that it also plans to submit this subgroup data to the FDA in support of the pending NDA. Alimera has reported that it expects to
submit the new safety and efficacy data to the FDA by May 13, 2011. Under the Companys 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 and Retinal Vein Occlusion.

The Companys two
FDA-approved products utilize earlier generations of the Durasert technology system, second-generation Retisert® for the treatment of posterior uveitis and first-generation Vitrasert® for the treatment of AIDS-related cytomegalovirus
(CMV) retinitis. Both of these products and the technologies underlying them have been licensed to Bausch & Lomb Incorporated (Bausch & Lomb).

The Company has a collaboration agreement with Pfizer, Inc. (Pfizer) which provides for a joint research program aimed at
developing ophthalmic applications that are not licensed to others using certain of the Companys technologies.

BioSilicon, the Companys 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 preliminary studies, the Company is targeting BioSilicon as a key second prong of its drug delivery technology platform.

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 product candidates. The Company anticipates that existing capital resources of $23.1 million at March 31, 2011 should enable it to maintain its current and planned operations
into at least calendar year 2013. The Companys ability to fund its planned operations internally beyond then may be substantially dependent upon the FDA approval of ILUVIEN, and the timing thereof, which would result in a $25.0 million
milestone payment due from Alimera, as well as the successful commercialization of ILUVIEN by Alimera.

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

New accounting pronouncements
are issued periodically by the Financial Accounting Standards Board and are adopted by the Company as of the specified effective dates. Unless otherwise discussed below, management believes that the impact of recently issued pronouncements will not
have a material impact on the Companys financial position, results of operations and cash flows or do not apply to the Companys operations.



|2. | Stockholders Equity
|-- | --------------------

On January 24, 2011, the Company completed a registered direct offering of 2,210,000 shares of its common stock and warrants to
purchase 552,500 shares of its common stock to institutional investors for gross proceeds of $11.05 million. The shares and warrants were sold in units, each unit consisting of one share together with 0.25 of one warrant, at a negotiated price of
$5.00 per unit. Each whole warrant has an exercise price of $5.00 per share and a five-year term. Placement agent fees and other share issue costs totaled $1.0 million.

The weighted average exercise price of these warrants translated to $ was $10.20 at March 31, 2011 and
$8.78 at March 31, 2010. Of the remaining 716,688 outstanding warrants at March 31, 2011, 511,209 expired in April 2011 and 205,479 have a remaining life of 1.30 years and an exercise price of A$7.68 ($7.92).

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 $334,000 for the three months ended March 31, 2011 compared to income
of $226,000 for the same period a year earlier and income of $1.1 million for the nine months ended March 31, 2011 compared to expense of $1.2 million a year earlier. The change in the fair value of these derivative liabilities is primarily
attributable to the combination of the spread between the Companys share price and the US$-equivalent exercise prices of the underlying warrants and the short 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. Upon amendment of the Alimera Agreement in March 2008, the Company received consideration of $12.0 million and Alimera cancelled $5.7 million of accrued development cost
liabilities, including related penalties and accrued interest, owed by the Company to Alimera. 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 make 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 amended 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 $35,000 and $156,000 for the three and nine months ended March 31, 2011, respectively, compared to $420,000 and $7.0 million for the three and nine
months ended March 31, 2010, respectively. These revenues represented the primary component of the Companys collaborative research and development revenue for these periods.

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
which the Company licensed Pfizer certain of the Companys technologies for use in the development of ophthalmic applications not licensed to others. The Pfizer Agreement provides for a joint research program, for which Pfizer pays the Company
a minimum of $500,000 quarterly in consideration of the Companys costs in performing the research program. These quarterly payments 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. The agreement also provides for potential development and sales-related milestone payments.

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 from Pfizer through March 31, 2011, totaling $7.25 million,
were classified in non-current deferred revenue.

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 $3.6
million, of which $450,000 was paid in July 2009, $630,000 is due in January 2012, and the remaining $2.5 million is due through April 2014.

Pursuant to a February 2009 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 four payments of $24,000 each were received through March 2011.

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 revenue for consideration allocated to the license arrangement on a straight-line basis over this period. The Company recognized collaborative research and
development revenue of $21,000 and $62,000 for the three and nine months ended March 31, 2011, respectively, compared to $20,000 and $101,000 for the three and nine months ended March 31, 2010, respectively. The remaining balance of
payments received, including minimum royalties, of $1.2 million was recorded as deferred revenue at March 31, 2011.

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 Retisert) 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 $277,000 at March 31, 2011 and $342,000 at June 30, 2010.

During the nine months ended March 31, 2011, $10.9 million of marketable securities were purchased and
$3.1 million matured. At March 31, 2011, marketable securities had maturities ranging between one and twelve months, with a weighted average maturity of 5.7 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 March 31, 2011 and
June 30, 2010, substantially all of the Companys interest-bearing cash equivalent balances were concentrated in one institutional money market fund that has investments consisting primarily of certificates of deposit, commercial paper,
time deposits, U.S. government agency securities, 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 or Level 2 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 following table summarizes the Companys assets and liabilities carried at fair value measured on a recurring basis at
March 31, 2011 and June 30, 2010 by valuation hierarchy:



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

Employee Share Option Plan

Following the Companys reincorporation in the U.S. in June 2008, no further options have been or will be granted
under the 2001 Plan.

The exercise prices of all outstanding options under the 2001 Plan at March 31, 2011 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 at that date. A total of 37,500 options vested during the nine months ended March 31, 2011.

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. The Company recorded an income tax benefit of $113,000 and $69,000 for the three and nine months ended March 31, 2011, respectively, primarily related to a net $90,000 reduction of deferred tax
liabilities and earned foreign research and development tax credits, partially offset by estimated federal income taxes.

|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 and six month periods ended December 31, 2010 and 2009 as their inclusion would be anti-dilutive.

Potentially dilutive shares at March 31, 2011 and 2010 were as follows:

Item 2. Managements Discussion and Analysis of Financial Condition
and Results of Operations

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: ability to obtain additional capital uncertain; future losses; impairment of
intangibles; fluctuations in the fair values of certain outstanding warrants; fluctuations in operating results; decline of royalty income from Bausch & Lomb; Alimeras ability to obtain regulatory approval of ILUVIEN; Alimeras
ability to successfully commercialize ILUVIEN if approved; 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 find 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 for which a New Drug Application (NDA) has been filed with 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.

ILUVIEN®, our lead product candidate under FDA 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 (FAc) over a period of up to 3 years. ILUVIEN is licensed to Alimera Sciences, Inc
(Alimera). 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 and Retinal Vein Occlusion.

Based on analysis of 24-month data from Phase III trials, Alimera filed an NDA with
the FDA in June 2010 and registration filings in various European countries in July 2010. After granting Priority Review status, the FDA issued a Complete Response Letter (CRL) in December 2010, which communicated the FDAs decision
that the NDA for ILUVIEN for DME could not be approved in its then present form. In the CRL, the FDA asked for analyses of safety and

efficacy data through month 36, including exploratory analyses in addition to those analyses previously submitted in the NDA, to further assess the relative benefits and risks of ILUVIEN, as well
as other information. On February 3, 2011, Alimera reported 36-month safety and efficacy data from the completed clinical trials, which Alimera stated it would submit to the FDA as part of the pending NDA. On May 3, 2011, 36-month data for
the subgroup of patients who had been diagnosed with DME for three or more years at entry of the trials was reported. Alimera stated that it also plans to submit this subgroup data to the FDA in support of the pending NDA. Alimera has reported that
it expects to submit the new safety and efficacy data to the FDA by May 13, 2011.

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 Incorporated (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.

We have a collaboration agreement with Pfizer, Inc. (Pfizer), which
provides for a joint research program aimed at developing ophthalmic applications that are not licensed to others using certain of our technologies.

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 key second prong of our drug delivery technology platform.

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 (fiscal year 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 Annual Report on Form 10-K for
fiscal year 2010.

Revenues

Revenues decreased by $155,000, or 30%, to $360,000 for the three months ended March 31, 2011 as compared to $515,000 for the three months ended March 31, 2010. Collaborative research and
development revenue related to our Alimera Agreement totaled $35,000 for the three months ended March 31, 2011 as compared to $420,000 for the same period a year earlier.

We would be entitled to receive a $25.0 million milestone payment from Alimera if the FDA approves ILUVIEN. Absent FDA approval of ILUVIEN during the fiscal year ending June 30, 2011 (fiscal
year 2011), we expect to record an insignificant amount of collaborative research and development revenue attributable to the Alimera 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 agreement was completed as of June 30, 2010. Royalty income from sales of Retisert for the three months ended March 31, 2011 totaled $277,000
compared to $391,000 of royalties that would otherwise have been payable for the three months ended March 31, 2010.

Research and
Development

Research and development totaled $1.7 million for each of the three month periods ended March 31,
2011 and 2010. Increased personnel and pre-clinical studies costs were largely offset by the absence in the current year period of third-party costs of the BrachySil clinical program in the prior year period.

General and Administrative

General and administrative increased by $64,000, or 4%, to $1.8 million for the three months ended March 31, 2011 from $1.7 million
for the three months ended March 31, 2010. This increase was primarily attributable to increased stock-based compensation, partially offset by lower professional fees.

Change in Fair Value of Derivatives

Change in fair value of
derivatives represented income of $334,000 for the three months ended March 31, 2011 compared to income of $226,000 for the three months ended March 31, 2010. This net change was due to an increasing spread between the US$-equivalent
weighted average exercise price of the A$-denominated warrants and the market price of our common shares during the current period. During the nine months ended March 31, 2011, 3.2 million, or 82%, of the A$-denominated warrants expired.
An additional 511,000 A$-denominated warrants expired in April 2011, leaving 205,000 warrants outstanding with an expiration date of July 2012.

Utilizing the Black-Scholes valuation model, we record the fair value of warrants 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 will continue to affect our operating results until these warrants expire in July 2012.

Revenues

Revenues decreased by $6.1 million, or 83%, to $1.3 million for the nine months ended March 31, 2011 from $7.3 million for the nine months ended March 31, 2010, reflecting the completion of the
21.5 month performance obligation period through December 31, 2009 during which we amortized to revenues the consideration received from Alimera in connection with the amendment of the Alimera Agreement. Collaborative research and development
revenue related to our Alimera Agreement totaled $156,000 for the nine months ended March 31, 2011 as compared to $7.0 million for the nine months ended March 31, 2010.

##### Table of Contents

Royalty income from sales of Retisert for the nine months ended March 31, 2011 totaled
$952,000 compared to $1.1 million of royalties that would otherwise have been payable for the nine months ended March 31, 2010 absent the royalty advance agreement.

Research and Development

Research and development decreased by
$195,000, or 4%, to $5.0 million for the nine months ended March 31, 2011 compared to $5.2 million for the nine months ended March 31, 2010. The combination of a $208,000 Federal research grant and the absence in the current year of
third-party costs of the BrachySil clinical program in the prior year period were partially offset by increased personnel and pre-clinical studies costs.

General and Administrative

General and administrative increased by
$726,000, or 14%, to approximately $5.9 million for the nine months ended March 31, 2011 from approximately $5.2 million for the nine months ended March 31, 2010. 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 $1.1 million for the nine months ended March 31, 2011 compared to expense
of approximately $1.2 million for the nine months ended March 31, 2010. This net change was due to the increased spread between the US$-equivalent weighted average exercise price of the A$-denominated warrants and the market price of our common
shares during the current period compared to a corresponding decrease in the spread for the prior year period and was also impacted by the expiration of 3.2 million, or 82%, of the A$-denominated warrants during the nine months ended
March 31, 2011.

Liquidity and Capital Resources

During the past three fiscal years, we have financed our operations primarily from payments received pursuant to collaboration agreements and, to a lesser degree, from sales of our equity securities. In
January 2011, we sold 2,210,000 shares of common stock and warrants to purchase 552,500 shares to institutional investors for net proceeds of approximately $10.0 million. At March 31, 2011, our principal sources of liquidity consisted of cash,
cash equivalents and marketable securities totaling $23.1 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 March 31, 2011 ranging from 1 to 12 months.

With the exception of fiscal year 2010,
we have incurred operating losses each year since inception and, at March 31, 2011, we had a total accumulated deficit of $226.8 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 achieves regulatory approval and sufficient revenues. We believe we can fund our operations as currently conducted into at least calendar year 2013. Whether we will require, or desire, additional capital will be
influenced by many factors, including, but not limited to:



| |  |  | the timely development and regulatory approval and successful commercialization of ILUVIEN and receipt of milestone, royalty and other payments;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------



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



| |  |  | our ability to establish and maintain strategic arrangements for products and 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 any patent claims; and
| | - |  | -----------------------------------------------------------------------------------------------------------------



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

##### Table of Contents

Absent adequate levels of funding from new and existing collaboration agreements and/or
financing transactions, management currently believes that our cash position thereafter depends significantly on approval of ILUVIEN by the FDA and foreign regulatory authorities and the initiation and success of marketing of ILUVIEN. However, there
is no assurance that the FDA or other regulatory authorities will approve ILUVIEN or that ILUVIEN will achieve market acceptance even if it is approved.

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. The state
of the economy and the financial and credit markets at the time we seek additional financing may make it more difficult and more expensive to obtain. 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 $706,000 to $4.4 million for the nine months ended
March 31, 2011 compared to $3.7 million for the nine months ended March 31, 2010. The net increase of cash used in operating activities consisted of (i) the absence in the current year period of $900,000 of Alimera conditional note
payments and a $450,000 of Intrinsiq minimum royalty payment received during fiscal 2010 and (ii) a $680,000 increase in professional fees, partially offset by (i) $1.0 million of Retisert royalty payments received following the June 2010
completion of a royalty advance agreement with Bausch & Lomb and (ii) receipt of a $208,000 Federal research grant.

Net cash used in investing activities consisted predominantly of $10.9 million of purchases, net of $3.1 million of maturities, of marketable securities during the nine months ended March 31, 2011.
No cash was used in investing activities for the nine months ended March 31, 2010.

Net cash provided by financing
activities of $10.1 million for the nine months ended March 31, 2011 consisted of the net proceeds of the common stock and warrants offering. Net cash provided by financing activities of $802,000 for the nine months ended March 31, 2010
consisted of the exercise of investor warrants and employee stock options.

We had no borrowings or line of credit facilities
as of March 31, 2011.

Off-Balance Sheet Arrangements

We had no off-balance sheet arrangements as of March 31, 2011 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 March 31, 2011, the balance of our derivative liabilities, which relate to warrants denominated in A$, totaled $180,000 and was determined using the Black-Scholes valuation model. The change in
fair value of derivatives resulted in income of $1.1 million for the nine months ended March 31, 2011 and expense of $1.2 million for the nine-month period a year earlier.

Our financial position and results of operations will continue to be sensitive to future revaluations of these derivative liabilities. At
March 31, 2011, these warrants had a weighted average remaining contractual life of approximately 4.5 months and a weighted average exercise price of $10.20 per share compared to the $3.92 NASDAQ closing price of our common shares on that date.
Of the 716,688 warrants outstanding at March 31, 2011, 511,209 warrants expired during April 2011 and the remaining 205,479 warrants have an expiry date of July 2012. The primary factor that impacts the change in fair value of these derivatives
is the change in the spread between our share price and the US$-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 further 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 March 31, 2011
to assumed increases or decreases of our share price at March 31, 2011:

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 March 31, 2011, the weakening
of the U.S. dollar compared to the comparable period of the prior year resulted in a net increase in research and development expenses of $20,000. 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
March 31, 2011, compared to December 31, 2010, the weakening of the U.S. dollar in relation to the Pound Sterling resulted in a net increase of $523,000 in stockholders equity due to the translation of £8.9 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 March 31, 2011 in relation to the Pound Sterling, our
stockholders equity at March 31, 2011 would have decreased or increased, respectively, by $715,000.

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.

##### Table of Contents

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 March 31, 2011. 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 March 31, 2011, 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.

PART II: OTHER INFORMATION

Item 1A. Risk Factors

RISKS RELATED TO OUR COMPANY AND OUR BUSINESS

We may be required to seek additional
capital in order to fund our operations, and our ability to obtain additional capital is uncertain.

Our cash, cash
equivalents and marketable securities totaled $23.1 million at March 31, 2011, and included net proceeds of $10.1 million in a registered direct offering completed on January 24, 2011. We believe we can fund our operations as currently
conducted into at least calendar year 2013. Whether we will require, or desire, additional capital will be influenced by many factors, including, but not limited to:



| |  |  | the timely development and regulatory approval and successful commercialization of ILUVIEN and receipt of milestone, royalty and other payments;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------



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



| |  |  | our ability to establish and maintain strategic arrangements for products and 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 any patent claims; and
| | - |  | -----------------------------------------------------------------------------------------------------------------



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

In particular, our future cash position depends significantly on approval of ILUVIEN by the FDA and foreign
regulatory authorities and the initiation and success of marketing of ILUVIEN. Alimera has agreed to pay us $25 million upon FDA approval of ILUVIEN for DME. In addition, we will be entitled to 20% of any future profits, as defined, on sales of
ILUVIEN by Alimera, subject to an 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. However, there is no assurance that the FDA or other regulatory authorities will approve ILUVIEN or that ILUVIEN will achieve market acceptance even if it is approved.

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. The state of the economy and the financial and credit markets at the time we seek additional financing may make it more difficult and more expensive to obtain. If available, additional equity
financing may be dilutive to stockholders, debt financing may involve restrictive covenants or



24

##### Table of Contents

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.

We have a history of losses and may incur losses in the future.

With the exception of fiscal year 2010, we have incurred operating losses since our inception in 2000. For fiscal
year 2010, we recorded net income of $8.8 million, primarily due to the accelerated payment in full by Alimera of a $15.0 million conditional note. For the fiscal years ended June 30, 2009 and 2008, we incurred net losses of $2.5 million and
$75.7 million, respectively. We incurred a net loss of $8.5 million for the nine months ended March 31, 2011 and expect to incur net losses for the balance of fiscal year 2011 and for the foreseeable future unless ILUVIEN is approved and
successfully commercialized. Even if ILUVIEN is approved and marketed, our profit share on sales of ILUVIEN, combined with any royalty income from our current products, and any other sources of revenue, may not be sufficient to result in
profitability on an ongoing basis.

Our results could be adversely affected as a result of the impact of impairment of our intangible
assets, which could adversely affect the price of our securities.

Impairment charges on our intangible assets could
have a material effect on our results of operations, which could, in turn, adversely affect the price of our securities. We recorded significant amounts of intangible assets in connection with earlier acquisitions. We took a $60.1 million impairment
charge on goodwill as of June 30, 2008 (which reduced the carrying value of our goodwill to zero) and a $45.3 million impairment charge on the recorded value of our Durasert intangible asset as of June 30, 2007. We still had $22.4 million
of intangible assets on our balance sheet as of March 31, 2011, of which $15.3 million related to our BioSilicon technology and $7.1 million related to our Durasert technology. We will continue to conduct impairment analyses of our intangible
assets as required, and we may be required to take impairment charges in the future, which could be significant.

Our results could be
adversely affected by non-cash charges due to fluctuations in the fair values of certain of our outstanding warrants, which could adversely affect the price of our securities.

We previously issued warrants denominated in Australian dollars (A$). The fair values of these warrants have been recorded as derivative
liabilities on our balance sheet. We are required to assess the fair value of these warrants at each balance sheet date, and changes in their fair values result in adjustments to our recorded derivative liabilities, and corresponding gains or losses
in our statements of operations. The fair values of these warrants are sensitive to changes in our share price, among other factors, and are measured using the Black-Scholes valuation model. Fluctuations in the fair values of these warrants could be
substantial and will continue to affect our operating results until these warrants expire in July 2012.

Our operating results may
fluctuate significantly from period to period.

Our operating results have fluctuated significantly from period to period in the past
and may continue to do so in the future due to many factors, including:



| |  |  | the timing, receipt and amount of payments, if any, from current and potential future collaboration partners, including, without limitation,
collaborative research, milestone and royalty payments, and the revenue recognition policies related thereto;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | changes in accounting estimates, policies or principles;
| | - |  | --------------------------------------------------------



| |  |  | the entry into, or termination of, collaboration agreements;
| | - |  | ------------------------------------------------------------



| |  |  | the scope, duration and effectiveness of our collaboration arrangements;
| | - |  | ------------------------------------------------------------------------



| |  |  | the quarterly income or expense amounts recorded from the revaluation of our derivative liabilities;
| | - |  | ----------------------------------------------------------------------------------------------------



| |  |  | the amount of research and development costs, including pre-clinical studies and clinical trials, that we fund internally;
| | - |  | --------------------------------------------------------------------------------------------------------------------------



| |  |  | general and industry-specific adverse economic conditions that may affect, among other things, our and our collaborators operations and financial
results; and
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | impairment write-downs of one or more of our intangible assets.
| | - |  | ---------------------------------------------------------------

Due to fluctuations in our operating results, quarterly comparisons of our financial results may not necessarily be meaningful, and
investors should not rely upon such results as an indication of future performance. In addition, investors may react adversely if our reported operating results are less favorable than in a prior period or are less favorable than those anticipated
by investors in the financial community, which may result in a decrease in our stock price.

Our royalty income from Bausch & Lomb may continue to decline.

The annual trend of the royalties from Bausch & Lomb for Retisert (including the historical amounts retained by
Bausch & Lomb) and Vitrasert has declined and may continue to do so. There is no assurance that Bausch & Lomb will continue to market either or both of these products. We do not expect that our royalty payments from
Bausch & Lomb for these products will ever become a material source of revenue for us.

RISKS RELATED TO THE DEVELOPMENT AND
COMMERCIALIZATION OF OUR PRODUCTS AND PRODUCT CANDIDATES

We do not know if the FDA or other regulatory authorities will approve
ILUVIEN for DME. If Alimera is unable to obtain regulatory approval for and successfully commercialize ILUVIEN, or experiences significant delays in doing so, our business will be materially harmed.

Alimera will not be able to market ILUVIEN for DME in the U.S. unless and until it receives FDA approval. Our ability to generate
significant revenues from this product depends on the ability of Alimera to obtain regulatory approval for and successfully commercialize ILUVIEN. Based on Alimeras analysis of the month 24 clinical readout of data from the FAME Study
(24 Month Data), Alimera filed a New Drug Application (NDA) for approval of the low dose of ILUVIEN in the United States in June 2010, followed by registration filings in Austria, France, Germany, Italy, Portugal and Spain in
July 2010. The FDA accepted Alimeras submission and granted a Priority Review. The FDA issued a Complete Response Letter (CRL) to Alimera in December 2010, which communicated the FDAs decision that the NDA for ILUVIEN for DME
could not be approved in its then present form.

In the CRL, the FDA asked for analyses of safety and efficacy of the clinical
readout of data from the FAME Study through month 36 (36 Month Data), including certain exploratory analyses in addition to analyses previously submitted in the NDA, to further assess the relative benefits and risks of ILUVIEN. In the
CRL, the FDA requested additional information regarding controls and specifications concerning the manufacturing, packaging and sterilization of ILUVIEN, which Alimera reported it was in the process of compiling. Additionally, the FDA indicated in
the CRL that it had observed deficiencies in current good manufacturing practices (cGMP) during facility inspections of two of Alimeras third-party manufacturers, which were completed in August and September of 2010, and that all
facilities and controls will need to comply with cGMP. Alimera reported that its third-party manufacturers were in the process of resolving these deficiencies.

On February 3, 2011, Alimera reported 36-month safety and efficacy data from the completed clinical trials, which Alimera stated it would submit to the FDA as part of the pending NDA. On May 3,
2011, 36-month data for the subgroup of patients who had been diagnosed with DME for three or more years at entry of the clinical trials was reported. Alimera stated that it also plans to submit this subgroup data to the FDA in support of the
pending NDA. Alimera has reported that it expects to submit the new safety and efficacy data to the FDA by May 13, 2011.

Alimera reported that the FDA has issued letters to both of its third-party manufacturers indicating that the inspections are now closed,
that Alimera believes that no further action is required and that it expects to include this information in the response it plans to file with the FDA.

In the NDA, Alimera included analyses of the 24 Month Data utilizing the full data set of all 956 patients randomized into Alimeras FAME Study, with data imputation employed using last
observation carried forward (LOCF) for data missing because of patients who discontinued the trial or were unavailable for follow-up (the Full Analysis Set) as well as other data sets including one that excludes from
the Full Analysis Set three patients who were enrolled but never treated, excludes data collected for patients subsequent to their use of treatments prohibited by Alimeras FAME Study protocol and imputes the last observation prior to the
protocol violation forward to month 24 using the LOCF method (the Modified ART Data Set). Both Alimera and we believed that the FDA would consider the Full Analysis Set the most relevant population for determining the safety and efficacy
of ILUVIEN based on the month 24 data. The primary efficacy endpoint at month 24 was met with statistical significance for both the low dose and the high dose of ILUVIEN in both trials using the Full Analysis Set. However, Alimeras FAME Study
protocol did not include the Full Analysis Set. The FAME Study protocol provides that the primary assessment of efficacy will be based on the Modified ART Data Set. Statistical significance was not achieved at month 24 for either the low dose or the
high dose of ILUVIEN in one trial using the Modified ART Data Set. Although the CRL requested certain exploratory analyses with respect to the 36 Month Data, it did not specify what data set or sets Alimera should utilize to analyze the 36 Month
Data. There is no assurance that the



26



---

##### Table of Contents

FDA will utilize the Full Analysis Set and not the Modified ART Data Set or another data set in determining whether ILUVIEN is safe and effective. We do not know whether any analyses of the 36
Month Data will demonstrate to the FDA that ILUVIEN is safe and efficacious.

In order to obtain approval to market ILUVIEN
for DME in the U.S., Alimera will need to demonstrate to the FDA that ILUVIEN for DME is safe and efficacious and satisfy the FDA on each of the issues raised in the CRL. There is no assurance that the 36 Month Data for the full patient population
or for the subgroup with chronic DME or other responses provided by Alimera and its third-party manufacturers will be sufficient to satisfy the FDA. The FDA may not grant marketing approval or it may request additional information from Alimera,
including requesting data from additional clinical trials, and ultimately may not grant marketing approval for ILUVIEN. The FDA may limit the approval for ILUVIEN to a subgroup of DME patients such as those diagnosed with DME for three or more
years. In addition, Alimera will also require regulatory approvals to sell ILUVIEN for DME in other countries, and there is no assurance that it will receive those approvals.

If Alimera is not successful in obtaining regulatory approval for and commercializing ILUVIEN for DME, or is significantly delayed in doing so, our business will be materially harmed. Alimeras
ability to successfully obtain regulatory approval for and commercialize ILUVIEN will depend on, among other things, its ability to:



| |  |  | receive marketing approval from the FDA and similar foreign regulatory authorities;
| | - |  | -----------------------------------------------------------------------------------



| |  |  | maintain commercial manufacturing arrangements with third-party manufacturers;
| | - |  | ------------------------------------------------------------------------------



| |  |  | produce, or have its third-party manufacturers produce, sufficient quantities of ILUVIEN in a validated process to permit successful commercialization;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | launch commercial sales of ILUVIEN; and
| | - |  | ---------------------------------------



| |  |  | secure acceptance of ILUVIEN in the medical community and with third-party payors.
| | - |  | ----------------------------------------------------------------------------------

Alimera reported that it expects to obtain a regulatory agency waiver from the requirement to perform carcinogenicity studies of ILUVIEN
in animals. Alimeras month 18 readouts from its open-label Phase II human pharmacokinetic clinical trial (the PK Study) indicated to Alimera that there is negligible systemic absorption of the corticosteroid fluocinolone acetonide
(FAc) in patients being treated with ILUVIEN. However, Alimera may be unable to demonstrate negligible systemic absorption of FAc in its PK Study beyond month 18, or may not obtain a regulatory agency waiver from the requirement to
perform carcinogenicity studies of ILUVIEN in animals regardless. Alimera reported that if it is required to perform carcinogenicity studies of ILUVIEN in animals, the approval of ILUVIEN could be delayed by up to 36 months.

ILUVIEN utilizes FAc, a corticosteroid that has demonstrated undesirable side effects in the eye, and the success of ILUVIEN, therefore, will be
dependent upon achieving an acceptable risk/benefit profile.

ILUVIEN utilizes FAc, a corticosteroid whose use in the
eye has been associated with undesirable side effects such as increased incidence of intraocular pressure (IOP), which may increase the risk of glaucoma and cataract formation. Upon review of Alimeras NDA for the low dose of
ILUVIEN in the treatment of DME as well as the analysis of the 36 Month Data including the subgroup data, the FDA may conclude that Alimeras FAME Study did not demonstrate that ILUVIEN has sufficient levels of efficacy to outweigh the risks
associated with its side-effect profile. Conversely, the FDA may conclude that ILUVIENs side-effect profile does not demonstrate an acceptable risk/benefit relationship in line with ILUVIENs demonstrated efficacy. In the event of such
conclusions, Alimera may not receive regulatory approval from the FDA or from similar regulatory agencies in other countries.

Even if
Alimera receives regulatory approval for ILUVIEN, the FDA and other regulatory agencies may impose limitations on the indicated uses for which ILUVIEN may be marketed, may subsequently withdraw approval for ILUVIEN or may take other actions against
ILUVIEN that would be adverse to our business.

Regulatory agencies generally approve products for particular
indications. Alimera has indicated that it intends to file the subgroup data with respect to patients diagnosed with DME for three or more years in support of the pending NDA. If the FDA approves ILUVIEN only for this subgroup of patients, it may
reduce the size of the potential market for ILUVIEN. The FDA or another regulatory authority may further limit the indications of use.

Additionally, product approvals, once granted, may be withdrawn if problems occur after initial marketing. If and when ILUVIEN does receive regulatory approval or clearance, the marketing, distribution
and manufacture of ILUVIEN will be subject to regulation by the FDA in the United States and by similar entities in other countries. Alimera will need to comply with facility registration and product listing requirements of the FDA and similar
entities in other countries, and will need to adhere to the FDAs Quality System Regulations. Noncompliance with applicable FDA and similar entities requirements could result in warning letters, fines, injunctions, civil penalties, recall
or seizure of ILUVIEN, total or partial

suspension of production, refusal of regulatory agencies to grant approvals, withdrawal of approvals by regulatory agencies or criminal prosecution. Alimera also will need to maintain compliance
with federal, state and foreign laws regarding sales incentives, referrals and other programs.

If we or our licensees are unable to
complete clinical trials for our product candidates or do not receive the necessary regulatory approvals, we or our licensees will be unable to commercialize our product candidates.

Our current and future activities are and will be subject to stringent regulation by governmental authorities both in the United States
and in any other country in which our products are marketed. Before we or our licensees can manufacture, market and sell any of our product candidates, approval from the FDA and/or foreign regulatory authorities is required. Generally, in order to
obtain these approvals, pre-clinical studies and clinical trials must demonstrate that each of these product candidates is safe for human use and effective for its targeted disease or condition.

Our product candidates, other than ILUVIEN for DME, are in early stages of development. Product development involves a high degree of
risk, and only a small proportion of research and development programs result in an approved product. If clinical trials that may be conducted by us or our licensees for any of our product candidates do not provide the necessary evidence of safety
and effectiveness, those product candidates could not be manufactured and sold, and would not generate revenues. Clinical trials initiated by us or our licensees for product candidates may fail or be delayed by many factors, including the following:



| |  |  | our (or licensees) lack of sufficient funding to pursue trials rapidly or at all;
| | - |  | ----------------------------------------------------------------------------------



| |  |  | our (or our licensees) inability to attract clinical investigators for trials;
| | - |  | -------------------------------------------------------------------------------



| |  |  | our (or our licenses) inability to recruit patients in sufficient numbers or at the expected rate;
| | - |  | ---------------------------------------------------------------------------------------------------



| |  |  | our inability to reach agreement with a licensee to undertake the clinical trials;
| | - |  | ----------------------------------------------------------------------------------



| |  |  | adverse side effects;
| | - |  | ---------------------



| |  |  | failure of the trials to demonstrate a products safety and efficacy;
| | - |  | ---------------------------------------------------------------------



| |  |  | our (or our licensees) failure to meet FDA or other regulatory agency requirements for clinical trial design;
| | - |  | --------------------------------------------------------------------------------------------------------------



| |  |  | our (or our licensees) inability to follow patients adequately after treatment;
| | - |  | --------------------------------------------------------------------------------



| |  |  | changes in the design or manufacture of a product;
| | - |  | --------------------------------------------------



| |  |  | failures by, or changes in our (or our licensees) relationship with, contract research organizations, third-party vendors and investigators
responsible for pre-clinical testing and clinical trials;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | our (or our licensees) inability to manufacture sufficient quantities of materials for use in clinical trials;
| | - |  | ---------------------------------------------------------------------------------------------------------------



| |  |  | governmental or regulatory agency assessments of pre-clinical or clinical testing that differs from our (or our licensees) interpretations or
conclusions that product candidates meet quality standards for stability, quality, purity and potency; and
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | governmental or regulatory delays, or changes in approval policies or regulations.
| | - |  | ----------------------------------------------------------------------------------

Results from pre-clinical testing and early clinical trials often do not accurately predict results of later clinical trials. Data
obtained from pre-clinical and clinical activities are susceptible to varying interpretations, which may delay, limit or prevent regulatory approval. Data from pre-clinical studies, early clinical trials and interim periods in multi-year trials are
preliminary and may change, and final data from pivotal trials for such products may differ significantly. Adverse side effects may develop that delay, limit or prevent the regulatory approval of products, or cause such regulatory approvals to be
limited or even rescinded. Additional trials necessary for approval may not be undertaken or may ultimately fail to establish the safety and efficacy of our product candidates.

The FDA or other relevant regulatory agencies may not approve our product candidates for manufacture and sale, and any approval by the
FDA does not ensure approval by other regulatory agencies or vice versa (which could require us to comply with numerous and varying regulatory requirements, possibly including additional clinical testing). Any product approvals we or our licensees
achieve could also be withdrawn for failure to comply with regulatory standards or due to unforeseen problems after the products marketing approval. In either case, marketing efforts with respect to the affected product would have to cease. In
addition, the FDA or other regulatory agencies may impose limitations on the indicated uses for which a product may be marketed.

In addition to testing, regulatory agencies impose various requirements on manufacturers and sellers of products under their jurisdiction, such as packaging, labeling, manufacturing practices, record
keeping and reporting. Regulatory

agencies may also require post-marketing testing and surveillance programs to monitor a products effects. Furthermore, changes in existing regulations or the adoption of new regulations
could prevent us from obtaining, or affect the timing of, future regulatory approvals.

We have a limited ability to develop and market
products ourselves. If we are unable to find marketing or commercialization partners, or our marketing or commercialization partners do not successfully develop or market our products, we may be unable to effectively develop and market products on
our own.

We have limited product development capability and no marketing or sales staff. Developing products and
achieving market acceptance for them can require extensive and substantial efforts by experienced personnel as well as expenditure of significant funds. We may not be able to establish sufficient capabilities necessary to develop products and
achieve market penetration ourselves.

Our business strategy includes entering into collaborative and licensing arrangements
for the development and commercialization of our product candidates, and we currently have collaboration and licensing arrangements with Alimera, Pfizer, Bausch & Lomb and Intrinsiq Materials Cayman Limited. The curtailment or termination
of any of these arrangements could adversely affect our business, our ability to develop and commercialize our products, product candidates and proposed products and our ability to fund operations.

The success of these and future collaborative and licensing arrangements will depend heavily on the experience, resources, efforts and
activities of our licensees. Our licensees have, and are expected to have, significant discretion in making decisions related to the development of product candidates and the commercialization of products under these collaboration agreements. Risks
that we face in connection with our collaboration and licensing strategy include the following:



| |  |  | our collaborative and licensing arrangements are, and are expected to be, subject to termination under various circumstances, including on short notice
and without cause;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | we are required, and expect to be required, under our collaborative and licensing arrangements not to conduct specified types of research and
development in the field that is the subject of the arrangement, limiting the areas of research and development that we can pursue;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | our licensees may develop and commercialize, either alone or with others, products that are similar to or competitive with our products;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------



| |  |  | our licensees, consistent with other pharmaceutical and biotechnology companies that have historically acted similarly, may for a variety of reasons
change the focus of their development and commercialization efforts or decrease or fail to increase spending related to our products or product candidates, thereby limiting the ability of these products to reach their potential;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | our licensees may lack the funding, personnel or experience to develop and commercialize our products successfully or may otherwise fail to do so; and
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | our licensees may not perform their obligations, in whole or in part.
| | - |  | ---------------------------------------------------------------------

To the extent that we choose not to, or we are unable to, enter into future license agreements with marketing and sales partners and,
alternatively, seek to market and sell products ourselves, we would experience increased capital requirements to develop the ability to manufacture, market and sell future products. We may not be able to manufacture, market or sell our products or
future products independently in the absence of such agreements.

Our current licensees may terminate their agreements with us at any
time, and if they do, we will lose the financial benefits of those agreements and may not be able to develop and sell products currently licensed to them.

Our licensees have rights of termination under our agreements with them. Exercise of termination rights by one or more of our licensees may leave us without the financial benefits and development,
marketing or sales resources provided under the terminated agreement, which may have an adverse effect on our business, financial condition and results of operations. Additionally, our interests may not continue to coincide with those of our
partners, and our partners may develop, independently or with third parties, products or technologies that could compete with our products. Further, disagreements over rights or technologies or other proprietary interests may occur.

We have exclusively licensed certain of our controlled drug delivery technologies to Pfizer for certain ophthalmic applications. We have
negotiated and continue to negotiate with Pfizer about potential amendments to the agreement, but we cannot predict whether or how that agreement will be amended. Pfizer may terminate the agreement without penalty at



29

##### Table of Contents

any time and for any reason upon 60 days written notice. We have exclusively licensed our technology underlying Vitrasert and Retisert to Bausch & Lomb, which can terminate its
agreement with us without penalty at any time upon 90 days written notice. We have licensed the technology underlying ILUVIEN for DME and certain ophthalmic applications to Alimera. Alimera has the financial responsibility for the development
of ILUVIEN and any other licensed products developed under our collaboration agreement, along with sole responsibility for the commercialization of such licensed products. Alimera may abandon the development and commercialization of any licensed
product at any time.

Any of Pfizer, Alimera or Bausch & Lomb may decide not to continue to develop or to
commercialize any or all of the licensed products under their respective agreements, change strategic focus, pursue alternative technologies or develop competing products. While Pfizer and Bausch & Lomb have significant experience in the
ophthalmic field and have substantial resources, there is no assurance whether, and to what extent, that experience and those resources will be devoted to our technologies. Alimera has limited experience, and if approved, ILUVIEN would be its first
product. Because we do not currently have sufficient funding or internal capabilities to develop and commercialize our products and product candidates, decisions, actions, breach or termination of these agreements by Pfizer, Bausch & Lomb
or Alimera could delay or stop the development or commercialization of any of the products or product candidates licensed to such entities.

If our competitors and potential competitors develop products that receive regulatory approval before our product candidates are approved or reach
the market prior to our product candidates, are more effective or have fewer side effects than our products or product candidates or are more effectively marketed or cost less, our products or product candidates may not achieve the sales we
anticipate and could be rendered obsolete.

We believe that pharmaceutical, drug delivery and biotechnology companies,
research organizations, governmental entities, universities, hospitals, other nonprofit organizations and individual scientists are seeking to develop drugs, therapies, products, approaches or methods to treat our targeted diseases or their
underlying causes. For many of our targeted diseases, competitors have alternate therapies that are already commercialized or are in various stages of development ranging from discovery to advanced clinical trials. For example, Roche Group recently
reported positive results from its Phase III trials of Lucentis® for DME. Any of these drugs, therapies, products, approaches or methods may receive government approval or gain market acceptance more rapidly than our products and product
candidates, may offer therapeutic or cost advantages, or may cure our targeted diseases or their underlying causes completely, which could reduce demand for our products and product candidates and could render them noncompetitive or obsolete. For
example, sales of Vitrasert for the treatment of CMV retinitis, a disease that affects people with late-stage AIDS, declined significantly because of treatments that delay the onset of late-stage AIDS.

Many of our competitors and potential competitors have substantially greater financial, technological, research and development,
marketing and personnel resources than us. Our competitors may succeed in developing alternate technologies and products that, in comparison to the products we have and are seeking to develop:



| |  |  | are more effective and easier to use;
| | - |  | -------------------------------------



| |  |  | are more economical;
| | - |  | --------------------



| |  |  | have fewer side effects; or
| | - |  | ---------------------------



| |  |  | may otherwise render or products less competitive or obsolete.
| | - |  | --------------------------------------------------------------

Many of these competitors have greater experience in developing products, conducting clinical trials, obtaining regulatory approvals or
clearances and manufacturing and marketing products.

Our products and product candidates may not achieve and maintain market
acceptance, and may never generate significant revenues.

In both domestic and foreign markets, the commercial success
of our products and product candidates will require not only obtaining regulatory approvals but also obtaining market acceptance by retinal specialists and other doctors, patients, government health administration authorities and other third-party
payors. Whether and to what extent our products and product candidates achieve and maintain market acceptance will depend on a number of factors, including: demonstrated safety and efficacy, cost-effectiveness, potential advantages over other
therapies, our and our collaborative partners marketing and distribution efforts and the reimbursement policies of government and other third-party payors. In particular, if government and other third-party payors do not provide adequate
coverage and reimbursement levels for our products and product candidates, the market acceptance of our products and product candidates will be limited. Both government and other third-party payors attempt to contain healthcare costs by limiting
coverage and the level of reimbursement for products and, accordingly, they might challenge the price and cost-effectiveness of our products, or refuse to provide coverage for uses of our products for certain disease indications. If our products and
product candidates fail to achieve and maintain market acceptance, they may fail to generate significant revenues and our business may be significantly harmed.

##### Table of Contents

Guidelines, recommendations and studies published by various organizations could reduce the use of our
products and product candidates.

Government agencies, professional societies, practice management groups, private
health and science foundations and organizations focused on various diseases may publish guidelines, recommendations or studies related to our products and product candidates or our competitors products. Any such guidelines, recommendations or
studies that reflect negatively on our products or product candidates could result in decreased use, sales of, and revenues from, one or more of our products and product candidates. Furthermore, our success depends in part on our and our
partners ability to educate healthcare providers and patients about our products and product candidates, and these education efforts could be rendered ineffective by, among other things, third-parties guidelines, recommendations or
studies.

RISKS RELATED TO OUR INTELLECTUAL PROPERTY

We rely heavily upon patents and trade secrets to protect our proprietary technologies. If we fail to protect our intellectual property or infringe on others technologies, our ability to
develop and market our products and product candidates may be compromised.

Our success is dependent on whether we can
obtain patents, defend our existing patents and operate without infringing on the proprietary rights of third parties. As of March 31, 2011, we had 180 patents and 160 pending patent applications, including patents and pending applications
covering our Durasert, BioSilicon and CODRUG technologies. Intellectual property protection of our technologies is uncertain. We expect to seek to patent and protect our proprietary technologies. However, there is no assurance that any
additional patents will be issued to us as a result of our pending or future patent applications or that any of our patents will withstand challenges by others. In addition, we may not have sufficient funds to patent and protect our proprietary
technologies to the extent that we would desire, or at all. If we were determined to be infringing any third party patent, we could be required to pay damages, alter our products or processes, obtain licenses, pay royalties or cease certain
operations. We may not be able to obtain any required licenses on commercially favorable terms, if at all. In addition, many foreign country laws may treat the protection of proprietary rights differently from, and may not protect our proprietary
rights to the same extent as, laws in the United States and Patent Co-operation Treaty countries.

Prior art may reduce the
scope or protection of, or invalidate, our patents. Previously conducted research or published discoveries may prevent our patents from being granted, invalidate issued patents or narrow the scope of any protection obtained. Reduction in scope of
protection or invalidation of our licensed or owned patents, or our inability to obtain patents, may enable other companies to develop products that compete with our products and product candidates on the basis of the same or similar technology. As
a result, our patents and those of our licensors may not provide any or sufficient protection against competitors. While we have not been, and are not currently involved in, any litigation over intellectual property, such litigation may be necessary
to enforce any patents issued or licensed to us or to determine the scope and validity of third party proprietary rights. We may also be sued by one or more third parties alleging that we infringe their intellectual property rights. Any intellectual
property litigation would be likely to result in substantial costs to us and diversion of our efforts, and could prevent or delay our discovery or development of product candidates. If our competitors claim technology also claimed by us, and if they
prepare and file patent applications in the U.S. or other jurisdictions, we may have to participate in interference proceedings declared by the U.S. Patent and Trademark Office or the appropriate foreign patent office to determine priority of
invention, which could result in substantial cost to us and diversion of our efforts. Any such litigation or interference proceedings, regardless of the outcome, could be expensive and time consuming. Litigation could subject us to significant
liabilities to third parties, requiring disputed rights to be licensed from third parties and/or requiring us to cease using certain technologies.

We also rely on trade secrets, know-how and technology that are not protected by patents to maintain our competitive position. We try to protect this information by entering into confidentiality
agreements with parties that have access to it, such as our corporate partners, collaborators, employees, and consultants. Any of these parties could breach these agreements and disclose our confidential information, or our competitors may learn of
the information in some other way. If any material trade secret, know-how or other technology not protected by a patent were to be disclosed to or independently developed by a competitor, our competitive position could be materially harmed.

RISKS RELATED TO OUR BUSINESS, INDUSTRY, STRATEGY AND OPERATIONS

If we fail to retain some or all of our key personnel, our business could suffer.

We are dependent upon the principal members of our management, administrative and scientific staff. In addition, we believe that our future success in developing our products and achieving a competitive
position will depend to a large



31

##### Table of Contents

extent on whether we can attract and retain additional qualified management and scientific personnel. There is strong competition for such personnel within the industry in which we operate and we
may not be able to continue to attract such personnel either to Massachusetts, where much of our research and development is conducted, or to Malvern in the U.K. As we have a small number of employees and our products are unique and highly
specialized, the loss of the services of one or more of the senior management or scientific staff, or the inability to attract and retain additional personnel and develop expertise as needed, could have a material adverse effect on our results of
operations and financial condition.

If we are subject to product liability suits, we may not have sufficient insurance to cover
damages.

The testing, manufacturing, and marketing and sale of the products utilizing our technologies involve risks
that product liability claims may be asserted against us and/or our licensees. Our current clinical trial and product liability insurance may not be adequate to cover damages resulting from product liability claims. Regardless of their merit or
eventual outcome, product liability claims could require us to spend significant time, money and other resources to defend such claims, could result in decreased demand for our products and product candidates or result in reputational harm and could
result in the payment of a significant damage award. Our product liability insurance coverage is subject to deductibles and coverage limitations and may not be adequate in scope to protect us in the event of a successful product liability claim.
Further, we may not be able to acquire sufficient clinical trial or product liability insurance in the future on reasonable commercial terms, if at all.

The trend towards consolidation in the pharmaceutical and biotechnology industries may adversely affect us.

There is an ongoing trend of consolidation in the pharmaceutical and biotechnology industries. This consolidation trend could result in the remaining companies having greater financial resources and
technological capabilities, thus intensifying competition. This trend could also result in fewer potential collaboration partners or licensees for our product candidates. In addition, if a consolidating company is already doing business with our
competitors, we could lose existing or potential future licensees or collaboration partners as a result of such consolidation.

If we
fail to comply with environmental laws and regulations, our ability to manufacture and commercialize products may be adversely affected.

Medical and biopharmaceutical research and development involves the controlled use of hazardous materials, such as radioactive compounds and chemical solvents. We are subject to federal, state and local
laws and regulations in the U.S. and abroad governing the use, manufacture, storage, handling and disposal of such materials and waste products. We could be subject to both criminal liability and civil damages in the event of an improper or
unauthorized release of, or exposure of individuals to, hazardous materials. In addition, claimants may sue us for injury or contamination that results from our use or the use by third parties of these materials, and our liability may exceed our
total assets. Compliance with environmental laws and regulations is expensive, and current or future environmental regulations may impair our research, development or production efforts or harm our operating results.

If we encounter problems with product manufacturing, we could experience delays in product development and commercialization, which would adversely
affect our future profitability.

Our ability to conduct timely pre-clinical and clinical research and development
programs, obtain regulatory approvals, develop and commercialize our product candidates will depend, in part, upon our and our collaborative partners ability to manufacture our products and product candidates, either directly or through third
parties, in accordance with FDA and other regulatory requirements. The manufacture, packaging and testing of our products and product candidates are regulated by the FDA and similar foreign regulatory entities and must be conducted in accordance
with applicable cGMP. Any change in a manufacturing process or procedure used for one of our products or product candidates, including a change in the location at which a product or product candidate is being manufactured or in the third-party
manufacturer being used, may require the FDAs and similar foreign regulatory entities prior review and/or approval in accordance with applicable cGMP regulations. Additionally, the FDA and similar foreign regulatory entities may
implement new standards, or change their interpretation and enforcement of existing standards, for the manufacture, packaging and testing of products at any time.

There are a limited number of manufacturers that operate under cGMP regulations that are both capable of manufacturing our products and product candidates and are willing to do so. Failure by us, our
collaborative partners, or our or their third-party manufacturers, to comply with applicable manufacturing requirements could result in sanctions being imposed on us, including fines, injunctions, civil penalties, failure of regulatory authorities
to grant marketing approval of our product candidates, delays, suspension or withdrawal of approvals, license revocation, seizures or recalls of product, operating restrictions and criminal prosecutions. In addition, we or our collaborative partners
may not be able to manufacture our product candidates successfully or have a third party manufacture them in a cost-effective manner. If we or our collaborative partners are unable to develop our own manufacturing facilities or to obtain or retain
third-party manufacturing on acceptable terms, we may not be able to conduct certain future pre-clinical and clinical testing or to supply commercial quantities of our products.

We manufacture supplies in connection with pre-clinical or clinical studies conducted by us
or our collaboration partners. Under our collaboration agreements with Alimera, Pfizer and Bausch & Lomb, we have provided our licensees the exclusive rights to manufacture commercial quantities of products, once approved for marketing. Our
current reliance on third-party manufacturers entails risks, including:



| |  |  | the possibility that third parties may not comply with the FDAs cGMP regulations, other regulatory requirements, and those of similar foreign
regulatory bodies, and may not employ adequate quality assurance practices;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | supply disruption, deterioration in product quality or breach of a manufacturing or license agreement by the third party because of factors beyond our
control;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the possible termination or non-renewal of a manufacturing or licensing agreement with a third party at a time that is costly or inconvenient to us;
and
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | our inability to identify or qualify an alternative manufacturer in a timely manner, even if contractually permitted to do so.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------

Alimera has contracted with third party manufacturers with respect to the manufacture of the components of
ILUVIEN. Our business could be significantly harmed if these third parties are not able to manufacture ILUVIEN in compliance with cGMP or to satisfy demand for ILUVIEN and alternative sources are not available. In addition, the materials necessary
to produce ILUVIEN or to formulate the active pharmaceutical ingredient may not be available on commercially reasonable terms, or at all, which could affect the development and commercialization of ILUVIEN.

Problems associated with international business operations could affect our ability to manufacture and sell our products. If we encounter such
problems, our costs could increase and our development of products could be delayed.

We currently maintain offices
and research and development facilities in the U.S. and the U.K., and we intend to license products for sale and/or sell products in most major world healthcare markets. A number of risks are inherent in our international strategy. In order for us
to license and manufacture our products, we must obtain country and jurisdiction-specific regulatory approvals or clearances to comply with regulations regarding safety and quality. We may not be able to obtain or maintain regulatory approvals or
clearances in such countries, and we may be required to incur significant costs in obtaining or maintaining foreign regulatory approvals or clearances. In addition, our operations and revenues may be subject to a number of risks associated with
foreign commerce, including the following:



| |  |  | staffing and managing foreign operations;
| | - |  | -----------------------------------------



| |  |  | political and economic instability;
| | - |  | -----------------------------------



| |  |  | foreign currency exchange fluctuations;
| | - |  | ---------------------------------------



| |  |  | foreign tax laws, tariffs and freight rates and charges;
| | - |  | --------------------------------------------------------



| |  |  | timing and availability of export licenses;
| | - |  | -------------------------------------------



| |  |  | inadequate protection of intellectual property rights in come countries; and
| | - |  | ----------------------------------------------------------------------------



| |  |  | obtaining required government approvals.
| | - |  | ----------------------------------------

Credit and financial market conditions may exacerbate certain risks affecting our business.

Sales of our products depend on the availability and extent of reimbursement from government and other third-party payors. Difficult credit and financial market conditions may increase the risk that
government and other third-party payors will reduce the availability or extent of reimbursement for our products, and the risk that third-party payors will delay or default on reimbursement obligations.

Development and sales of our products and product candidates also heavily depend on collaborative partners and third-party suppliers.
Difficult credit and financial market conditions may increase the risk that there are delays, disruptions or defaults in the performance of these third parties obligations to us.

Legislative or regulatory changes may adversely affect our business, operations and financial results.

Our industry is highly regulated and new laws, regulations and judicial decisions, and new interpretations of existing laws, regulations and judicial decisions, may adversely affect our business,
operations and financial results.

##### Table of Contents

The Patient Protection and Affordable Care Act of 2010, as amended by the Health Care and
Education Reconciliation Act of 2010 (the PPACA), is intended to expand U.S. healthcare coverage primarily through the imposition of health insurance mandates on employers and individuals and expansion of the Medicaid program. Several
provisions of this new law could significantly reduce payments from Medicare and Medicaid for our products and product candidates over the next 10 years, resulting in potentially significant reductions of our revenues. The PPACAs effects
cannot be fully known until its provisions are implemented, and the Centers for Medicare & Medicaid Services, and other federal and state agencies, issue applicable regulations or guidance. Proposed U.S. state healthcare reforms, and any
foreign healthcare reforms, also could alter the availability, methods and rates of reimbursements from the government and other third-party payors for our products and product candidates, and could adversely affect our business strategy, operations
and financial results.

The U.S. Food and Drug Administration Amendment Act of 2007 granted the FDA enhanced authority over
products already approved for sale, including authority to require post-marketing studies and clinical trials, labeling changes based on new safety information and compliance with risk evaluations and mitigation strategies approved by the FDA. The
FDAs exercise of this relatively new authority could result in delays and increased costs during product development, clinical trials and regulatory review and approval, increased costs following regulatory approval to assure compliance with
new post-approval regulatory requirements, and potential restrictions on the sale or distribution of approved products following regulatory approval.

RISKS RELATED TO OUR COMMON STOCK

The price of our common stock may be volatile.

The price of our common stock (including common stock represented by CHESS Depositary Interests (CDIs)) may be
affected by developments directly affecting our business and by developments out of our control or unrelated to us. The biotechnology sector, in particular, and the stock market generally, are vulnerable to abrupt changes in investor sentiment.
Prices of securities and trading volume of companies in the biotechnology industry, including ours, can swing dramatically in ways unrelated to, or that bear a disproportionate relationship to, operating performance. The price of our common stock
(and CDIs) and their trading volumes may fluctuate based on a number of factors including, but not limited to:



| |  |  | clinical trial results and other product and technological developments and innovations;
| | - |  | ----------------------------------------------------------------------------------------



| |  |  | FDA and other governmental regulatory actions, receipt and timing of approvals of our (or our licensees) product candidates, and any denials and
withdrawal of approvals;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | competitive factors, including the commercialization of new products in our markets by our competitors;
| | - |  | -------------------------------------------------------------------------------------------------------



| |  |  | advancements with respect to treatment of the diseases targeted by our product candidates;
| | - |  | ------------------------------------------------------------------------------------------



| |  |  | developments relating to collaborative partners, including execution, amendment and termination of agreements, achievement of milestones and receipt of
payments;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the success of our collaborative partners in marketing any approved products and the amount and timing of the royalties payable to us;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------

In addition, low trading volume in our common stock or our CDIs may increase their price volatility. Holders of our common stock and CDIs
may not be able to liquidate their positions at the desired time or price.

If the holders of our outstanding warrants and stock options
exercise their warrants and options, ownership of our common stock holders may be diluted, and our stock price may decline.

As of April 30, 2011, we had outstanding approximately 7.8 million investor warrants and 2.8 million employee and director options to acquire shares of our common stock, or approximately
33.7% of our shares on a fully diluted basis.

##### Table of Contents

Certain of the options are subject to performance conditions, and the exercise prices of all of these warrants and a small portion of the stock options were above the market price at that date.
The issuance of shares of our common stock upon exercise of our outstanding warrants and stock options would result in dilution to the interests of other holders of our common stock and could adversely affect our stock price. The overhang of
outstanding warrants and options may adversely affect our stock price. The warrant exercise prices may be adjusted under certain circumstances.

Pfizer owns a significant percentage of our common stock and is a collaborative partner and therefore may be able to influence our business in ways
that are not beneficial to you.

Pfizer owned approximately 9.0% of our outstanding shares as of April 30, 2011
and is a collaborative partner. As a result, Pfizer may be able to exert significant influence over our board of directors and how we operate our business. The concentration of ownership may also have the effect of delaying or preventing a change in
control of our company.

We have paid penalties pursuant to registration agreements with securities holders relating to resale
registration statements, and any requirement to pay such penalties in the future may have a material adverse effect on our financial condition.

We have registration rights agreements that require us to file and maintain the effectiveness of registration statements for the resale of our common stock, which provide for monetary penalties in the
event of our failure to do so. During the year ended June 30, 2007, we paid registration delay penalties of approximately $2.3 million in connection with then outstanding convertible notes. Our failure or inability to maintain the effectiveness
of any of our required registration statements or to adequately update information in the related prospectuses may subject us to additional penalties under our current registration rights agreements. Payment of additional penalties may have a
material adverse effect on our financial condition and may require us to suspend, curtail or terminate our operations or delay, reduce the scope of or eliminate one or more of our research and development programs, any of which could have a material
adverse effect on our business.

We do not currently intend to pay dividends on our common stock, and any return to investors is
expected to come, if at all, only from potential increases in the price of our common stock.

At the present time, we
intend to use available funds to finance our operations. Accordingly, while payment of dividends rests within the discretion of our board of directors, no cash dividends on our common shares have been declared or paid by us and we have no intention
of paying any such dividends in the foreseeable future.
