NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

1. BASIS OF PRESENTATION

     The accompanying unaudited condensed consolidated financial statements of Avanir Pharmaceuticals, Inc. (“Avanir”, “we”, or the “Company”) have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission (“SEC”) for interim reporting including the instructions to Form 10-Q. These condensed consolidated financial statements do not include all disclosures for annual audited financial statements required by accounting principles generally accepted in the United States of America (“U.S. GAAP”) and should be read in conjunction with the Company’s audited consolidated financial statements and related notes included in the Company’s Annual Report on Form 10-K for the year ended September 30, 2010. The Company believes these condensed consolidated financial statements reflect all adjustments (consisting only of normal, recurring adjustments) that are necessary for a fair presentation of the financial position and results of operations for the periods presented. Results of operations for the interim periods presented are not necessarily indicative of results to be expected for the year.

     The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts and the disclosures of commitments and contingencies in the financial statements and accompanying notes. Actual results could differ from those estimates.

     Certain amounts in the accompanying condensed consolidated financial statements have been reclassified to conform with the current period presentation.

2. DESCRIPTION OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Description of Business

     Avanir is a pharmaceutical company focused on acquiring, developing and commercializing novel therapeutic products for the treatment of central nervous system disorders. In October 2010, the U.S. Food and Drug Administration (“FDA”) approved NUEDEXTA^® (formally referred to as AVP-923 during clinical development), a unique proprietary combination of dextromethorphan/quinidine, for the treatment of pseudobulbar affect (“PBA”). The Company commenced promotion of NUEDEXTA in the United States in February 2011 and is currently pursuing approval of NUEDEXTA in Europe.

     The Company is also studying AVP-923 for use in different types of neuropathic pain. The Company has filed an Investigational New Drug application (“IND”) with the FDA to begin a large Phase II clinical trial of AVP-923, an investigational drug for the treatment of central neuropathic pain in patients with multiple sclerosis. The FDA has accepted the proposed clinical investigational plan included in the submission and the Company plans to enroll the first patient before the end of calendar 2011.

     AVP-923 has also successfully completed a Phase III trial for the treatment of patients with diabetic peripheral neuropathic pain (“DPN pain”).

     In addition to the Company’s focus on products for the central nervous system, the Company also has partnered programs in other therapeutic areas which may generate future income. The Company’s first commercialized product, docosanol 10% cream, (sold in the United States and Canada as Abreva^® by its marketing partner GlaxoSmithKline Consumer Healthcare) is the only over-the-counter treatment for cold sores that has been approved by the FDA. In 2008, the Company licensed all its monoclonal antibodies and remains eligible to receive milestone payments and royalties related to the sale of these assets.

     The Company’s operations are subject to certain risks and uncertainties frequently encountered by companies in the early stages of operations, particularly in the evolving market for small biotech and specialty pharmaceutical companies. Such risks and uncertainties include, but are not limited to, the occurrence of adverse safety events with

NUEDEXTA; that NUEDEXTA may not gain acceptance by the medical field or that the indicated use may not be clearly understood; the Company’s dependence on third parties for manufacturing and distribution of NUEDEXTA; that the Company may not adequately build or maintain the necessary sales, marketing, supply chain management and reimbursement capabilities on its own or enter into arrangements with third parties to perform these functions in a timely manner or on acceptable terms; the ability to successfully defend our intellectual property rights relating to NUEDEXTA; timing and uncertainty of achieving milestones in clinical trials; the acceptance of the IND application by the FDA; and obtaining approvals by the FDA and regulatory agencies in other countries. The Company’s ability to generate revenues in the future may depend on market acceptance of NUEDEXTA for the treatment of PBA and the timing and success of reaching clinical development milestones and obtaining regulatory approvals for other formulations for NUEDEXTA (referred to as “AVP-923”). The Company’s operating expenses depend substantially on the level of expenditures for the ongoing marketing of NUEDEXTA, clinical development activities for NUEDEXTA as well as AVP-923 and the rate of progress being made on such activities.

     Avanir was incorporated in California in August 1988 and was reincorporated in Delaware in March 2009.

Significant Accounting Policies

     The following represents an update for the nine months ended June 30, 2011 to the significant accounting policies described in the Company’s Annual Report on Form 10-K for the fiscal year ended September 30, 2010.

Concentration of Credit Risk and Sources of Supply

     As of June 30, 2011, approximately $54.2 million of the Company’s cash and cash equivalents were maintained in three separate money market mutual funds, and approximately $37.0 million of the Company’s cash and cash equivalents were maintained at three major financial institutions in the United States. At times, deposits held with the financial institutions may exceed the amount of insurance provided by the Federal Deposit Insurance Corporation (“FDIC”), which provides basic deposit coverage with limits up to $250,000 per owner. In addition to the basic insurance deposit coverage, the FDIC is providing temporary unlimited coverage for noninterest-bearing transaction accounts from December 31, 2010 through December 31, 2012. At June 30, 2011, such uninsured deposits totaled approximately $90.7 million of the $93.5 million of total cash and cash equivalents and restricted investments. Generally, these deposits may be redeemed upon demand and, therefore, are believed to bear minimal risk.

     Financial instruments that potentially subject the Company to concentrations of credit risk consist of cash and cash equivalents and trade receivables. The Company’s cash and cash equivalents are placed in various money market mutual funds and at financial institutions of high credit standing. The Company performs ongoing credit evaluations of its customers’ financial condition and would limit the amount of credit extended if necessary; however, the Company has historically required no collateral.

     The Company currently has sole suppliers for the active pharmaceutical ingredients (“APIs”) for NUEDEXTA and a sole manufacturer for the finished form of NUEDEXTA. In addition, these materials are custom and available from only a limited number of sources. Any material disruption in manufacturing could cause a delay in shipments and possible loss of revenue. If the Company is required to change manufacturers, the Company may experience delays associated with finding an alternative manufacturer that is properly qualified to produce NUEDEXTA in accordance with FDA requirements and the Company’s specifications.

Fair value of financial instruments

     At June 30, 2011 and September 30, 2010, the Company’s financial instruments included cash and cash equivalents, restricted investments in marketable securities, trade receivables, accounts payable, accrued expenses and other liabilities, and accrued compensation and payroll taxes. The carrying amount of cash and cash equivalents, trade receivables, accounts payable, accrued expenses and other liabilities, and accrued compensation and payroll taxes approximates fair value due to the short-term maturities of these instruments. The Company’s short-term and long-term restricted investments in marketable securities are carried at amortized cost which approximates fair value.

     Revenue recognition

     The Company has historically generated revenues from product sales, collaborative research and development arrangements, and other commercial arrangements such as royalties, the sale of royalty rights and sales of technology rights. Payments received under such arrangements may include non-refundable fees at the inception of the arrangements, milestone payments for specific achievements designated in the agreements, royalties on sales of products resulting from collaborative arrangements, and payments for the sale of rights to future royalties.

     The Company recognizes revenue when all of the following criteria are met: (1) persuasive evidence of an arrangement exists; (2) delivery has occurred or services have been rendered; (3) the Company’s price to the buyer is fixed or determinable; and (4) collectability is reasonably assured. Certain product sales are subject to rights of return. For products sold where the buyer has the right to return the product, the Company recognizes revenue at the time of sale only if (1) the Company’s price to the buyer is substantially fixed or determinable at the date of sale, (2) the buyer has paid the Company, or the buyer is obligated to pay the seller and the obligation is not contingent on resale of the product, (3) the buyer’s obligation to the Company would not be changed in the event of theft or physical destruction or damage of the product, (4) the buyer acquiring the product for resale has economic substance apart from that provided by the seller, (5) the Company does not have significant obligations for future performance to directly bring about resale of the product by the buyer, and (6) the amount of future returns can be reasonably estimated. The Company recognizes such product revenues when either it has met all the above criteria, including the ability to reasonably estimate future returns, when it can reasonably estimate that the return privilege has substantially expired, or when the return privilege has substantially expired, whichever occurs first.

     Product Sales — NUEDEXTA. NUEDEXTA is sold primarily to third-party wholesalers that, in turn, sell this product to retail pharmacies, hospitals, and other dispensing organizations. The Company has entered into agreements with wholesale customers, certain medical institutions and third-party payers throughout the United States. These agreements frequently contain commercial terms, which may include favorable product pricing and discounts and rebates payable upon dispensing the product to patients. Additionally, these agreements customarily provide the customer with rights to return the product, subject to the terms of each contract. Consistent with pharmaceutical industry practice, wholesale customers can return purchased product during an 18-month period that begins six months prior to the product’s expiration date and ends 12 months after the expiration date.

     At the present time, the Company is unable to reasonably estimate future returns due to the lack of sufficient historical returns data for NUEDEXTA. Accordingly, the Company invoices the wholesaler, records deferred revenue at gross invoice sales price less estimated cash discounts and distribution fees, and classifies the inventory shipped as inventories subject to return. The Company currently defers recognition of revenue and the related cost of product sales on shipments of NUEDEXTA until the right of return no longer exists, i.e. when the Company receives evidence that the products have been dispensed to patients. The Company estimates patient prescriptions dispensed using an analysis of third-party information. In the future, the Company plans to recognize product sales upon shipment to the customer when it believes it has sufficient data to develop reasonable estimates of expected returns based upon historical returns.

     The Company’s net product sales represent gross product sales less allowances for customer credits, including estimated discounts, rebates, chargebacks and co-pay assistance. These allowances provided by the Company to a customer are presumed to be a reduction of the selling prices of the Company’s products or services and, therefore, should be characterized as a reduction of revenue when recognized in the Company’s statement of operations. Allowances for discounts, rebates, chargebacks and co-pay assistance are estimated based on contractual terms with customers and sell-through data purchased from third party information. Product shipping and handling costs are included in cost of product sales.

     Product Sales — Active Pharmaceutical Ingredient docosanol (“docosanol”). Revenue from sales of the Company’s docosanol is recorded when title and risk of loss have passed to the buyer and provided the criteria for revenue recognition are met. The Company sells the docosanol to various licensees upon receipt of a written order for the materials. Shipments generally occur fewer than three times a year. The Company’s contracts for sales of the docosanol include buyer acceptance provisions that give the Company’s buyers the right of replacement if the delivered product does not meet specified criteria. That right requires that they give the Company notice within 30 days after receipt of the product. The Company has the option to refund or replace any such defective materials;

however, it has historically demonstrated that the materials shipped from the same pre-inspected lot have consistently met the specified criteria and no buyer has rejected any of the Company’s shipments from the same pre-inspected lot to date. Therefore, the Company recognizes revenue at the time of delivery without providing any returns reserve.

     Multiple Element Arrangements. The Company has, in the past, entered into arrangements whereby it delivers to the customer multiple elements including technology and/or services. Such arrangements have included some combination of the following: antibody generation services; licensed rights to technology, patented products, compounds, data and other intellectual property; and research and development services. At the inception of the arrangement, the Company analyzes its multiple element arrangements to determine whether the elements can be separated. If a product or service is not separable, the combined deliverables will be accounted for as a single unit of accounting.

     A delivered element can be separated from other elements when it meets both of the following criteria: (1) the delivered item has value to the customer on a standalone basis; and (2) if the arrangement includes a general right of return relative to the delivered item, delivery or performance of the undelivered item is considered probable and substantially in the Company’s control. If an element can be separated, the Company allocates amounts based upon the selling price of each element. The Company determines the selling price of a separate deliverable using the price it charges other customers when it sells that product or service separately; however, if the Company does not sell the product or service separately, it uses third-party evidence of selling price of a similar product or service to a similar situated customer. The Company considers licensed rights or technology to have standalone value to its customers if it or others have sold such rights or technology separately or its customers can sell such rights or technology separately without the need for the Company’s continuing involvement. The Company has not entered into any multiple element arrangement during fiscal 2011 or 2010, which required the Company to estimate selling prices.

     License Arrangements. License arrangements may consist of non-refundable upfront license fees, data transfer fees, research reimbursement payments, exclusive licensed rights to patented or patent pending compounds, technology access fees, and various performance or sales milestones. These arrangements are often multiple element arrangements.

     Non-refundable, up-front fees that are not contingent on any future performance by the Company, and require no consequential continuing involvement on its part, are recognized as revenue when the license term commences and the licensed data, technology and/or compound is delivered. Such deliverables may include physical quantities of compounds, design of the compounds and structure-activity relationships, the conceptual framework and mechanism of action, and rights to the patents or patents pending for such compounds. The Company defers recognition of non-refundable upfront fees if it has continuing performance obligations without which the technology, right, product or service conveyed in conjunction with the non-refundable fee has no utility to the licensee that is separate and independent of the Company’s performance under the other elements of the arrangement. In addition, if the Company has required continuing involvement through research and development services that are related to its proprietary know-how and expertise of the delivered technology, or can only be performed by the Company, then such up-front fees are deferred and recognized over the period of continuing involvement.

     Payments related to substantive, performance-based milestones in a research and development arrangement are recognized as revenues upon the achievement of the milestones as specified in the underlying agreements when they represent the culmination of the earnings process.

     Royalty Arrangements. The Company recognizes royalty revenues from licensed products when earned in accordance with the terms of the license agreements. Net sales amounts generally required to be used for calculating royalties include deductions for returned product, pricing allowances, cash discounts, freight and warehousing. These arrangements are often multiple element arrangements.

     Certain royalty arrangements require that royalties are earned only if a sales threshold is exceeded. Under these types of arrangements, the threshold is typically based on annual sales. For royalty revenue generated from the license agreement with GlaxoSmithKline (“GSK”), the Company recognizes royalty revenue in the period in which the threshold is exceeded. During the nine months ended June 30, 2011 and 2010, sales in excess of the threshold resulted in recognized royalty revenues from GSK of approximately $1.2 million and $914,000, respectively. For

royalty revenue generated from the license agreement with Azur Pharma (“Azur”), the Company recognizes revenue when it has determined that the threshold has been exceeded. During the nine months ended June 30, 2011 and 2010, sales in excess of the threshold resulted in recognized royalty revenues from Azur of approximately $527,000 and $516,000, respectively.

     When the Company sells its rights to future royalties under license agreements and also maintains continuing involvement in earning such royalties, it defers recognition of any upfront payments and recognizes them as revenues over the life of the license agreement. The Company recognizes revenues for the sale of an undivided interest of its Abreva^® license agreement to Drug Royalty USA under the “units-of-revenue method.” Under this method, the amount of deferred revenues to be recognized in each period is calculated by multiplying the ratio of the royalty payments due to Drug Royalty USA by GSK for the period to the total remaining royalties the Company expects GSK will pay Drug Royalty USA over the remaining term of the agreement by the unamortized deferred revenues.

Cost of product revenues

     Cost of product revenues includes third-party royalties and direct and indirect costs to manufacture product sold, including packaging, storage, shipping and handling costs and the write-off of obsolete inventory.

Recognition of Expenses in Outsourced Contracts

     Pursuant to management’s assessment of the services that have been performed on clinical trials and other contracts, the Company recognizes expenses as the services are provided. Such management assessments include, but are not limited to: (1) an evaluation by the project manager of the work that has been completed during the period, (2) measurement of progress prepared internally and/or provided by the third-party service provider, (3) analyses of data that justify the progress, and (4) management’s judgment. Several of the Company’s contracts, including subsequent amendments, extend across multiple reporting periods.

Share-Based Compensation

     The Company grants options, restricted stock units and restricted stock awards to purchase its common stock to its employees, directors and consultants under its stock option plans. The benefits provided under these plans are share-based payments that the Company accounts for using the fair value method.

     The fair value of each option award is estimated on the date of grant using a Black-Scholes-Merton option pricing model (“Black-Scholes model”) that uses assumptions regarding a number of complex and subjective variables. These variables include, but are not limited to, the Company’s expected stock price volatility, actual and projected employee stock option exercise behaviors, risk-free interest rate and expected dividends. Expected volatilities are based on historical volatility of the Company’s common stock and other factors. The expected terms of options granted are based on analyses of historical employee termination rates and option exercises. The risk-free interest rates are based on the U.S. Treasury yield in effect at the time of the grant. Since the Company does not expect to pay dividends on its common stock in the foreseeable future, the Company estimated the dividend yield to be 0%.

     Share-based compensation expense recognized during a period is based on the value of the portion of share-based payment awards that is ultimately expected to vest and is amortized under the straight-line attribution method. As share-based compensation expense recognized in the consolidated statements of operations for periods in fiscal 2011 and 2010 is based on awards ultimately expected to vest, it has been reduced for estimated forfeitures. The fair value method requires forfeitures to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. The Company estimates forfeitures based on its historical experience.

     Total compensation expense related to all of the Company’s share-based awards for the three and nine month periods ended June 30, 2011 and 2010 was comprised of the following:

		For the three months ended								For the nine months ended
		June 30,								June 30,
		2011				2010				2011				2010
Share-based compensation classified as:
Research and development expense		$	164,191			$	105,332			$	463,374			$	433,561
Selling, general and administrative expense			792,444				477,537				2,278,077				1,513,145
Total		$	956,635			$	582,869			$	2,741,451			$	1,946,706

		For the three months ended								For the nine months ended
		June 30,								June 30,
		2011				2010				2011				2010
Share-based compensation expense from:
Stock options		$	697,654			$	285,179			$	1,811,731			$	860,412
Restricted stock units			258,981				297,690				929,720				1,086,294
Total		$	956,635			$	582,869			$	2,741,451			$	1,946,706

     Since the Company provided a full valuation allowance related to its net deferred tax assets as of June 30, 2011, no excess tax benefits for the tax deductions related to share-based awards were recognized in the condensed consolidated statements of operations. Additionally, no incremental tax benefits were recognized from stock options exercised in the nine month periods ended June 30, 2011 and 2010 that would have resulted in a reclassification to reduce net cash used in operating activities with an offsetting increase in net cash provided by financing activities (See Note 10, “Employee Equity Incentive Plans”).

Income Taxes

     The Company accounts for income taxes and the related accounts under the liability method. Deferred tax assets and liabilities are determined based on the differences between the financial statement carrying amounts and the income tax bases of assets and liabilities. A valuation allowance is applied against any net deferred tax asset if, based on available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized.

     The Company recognizes any uncertain income tax positions on the income tax returns at the largest amount that is more-likely-than-not to be sustained upon audit by the relevant taxing authority. An uncertain income tax position will not be recognized if it has less than a 50% likelihood of being sustained.

     At June 30, 2011, the total unrecognized tax benefit resulting in a decrease in deferred tax assets and corresponding decrease in the valuation allowance is approximately $3.4 million. There are no unrecognized tax benefits included in the condensed consolidated balance sheet that would, if recognized, affect the effective tax rate.

     The Company’s policy is to recognize interest and/or penalties related to income tax matters in income tax expense. The Company had $0 accrued for interest and penalties on the Company’s condensed consolidated balance sheets at June 30, 2011 and September 30, 2010.

     The Company is subject to taxation in the U.S. and various state jurisdictions. The Company’s tax years for 1994 and forward are subject to examination by the U.S. and California tax authorities due to the carryforward of unutilized net operating losses and research and development credits.

     The Company does not foresee material changes to its gross uncertain income tax liability within the next twelve months.

     In July 2010, the Company applied for the Qualifying Therapeutic Discovery Project tax credit (“Therapeutic Credit”). The Therapeutic Credit allows qualifying business to claim a credit for 50% of their qualified investment in qualifying projects for tax years 2010 and 2009. In November 2010, the Company received notification from the Internal Revenue Service that it was granted a credit of approximately $244,000 related to the Therapeutic Credit. The Company elected to receive a cash grant in lieu of the credit which it received in May 2011. The cash grant is recorded as an offset to research and development expenses in the accompanying condensed consolidated statement of operations for the nine months ended June 30, 2011.

Recent Authoritative Guidance

     Proposed Amendments to Current Accounting Standards. The Financial Accounting Standard Board (“FASB”) is currently working on amendments to existing accounting standards governing a number of areas including, but not limited to, revenue recognition. In June 2010, the FASB issued an exposure draft, Revenue from Contracts with Customers, which would supersede most of the existing guidance on revenue recognition in Accounting Standards Codification Topic 605, Revenue Recognition. The FASB is going to re-expose this draft later this year. As the standard-setting process is still ongoing, the Company is unable to determine the impact this proposed change in accounting will have in the Company’s consolidated financial statements at this time.

     Fair Value Measurement. In May 2011, the FASB issued Accounting Standards Update No. 2011-04, “Fair Value Measurement (Topic 820): Amendment to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs” (“ASU No. 2011-04”). ASU No. 2011-04 amends the wording used to describe many of the requirements in U.S. GAAP for measuring fair value and disclosing information about fair value measurements. The amendments in this update achieve the objective of developing common fair value measurement and disclosure requirements, as well as improving consistency and understandability. Some of the requirements clarify the FASB’s intent about the application of existing fair value measurement requirements while other amendments change a particular principle or requirement for measuring fair value or for disclosing information about fair value measurements. The amendments in this ASU are effective prospectively for interim and annual periods beginning after December 15, 2011, with no early adoption permitted. The Company is required to adopt ASU No. 2011-04 effective its second quarter fiscal 2012. The Company is currently evaluating the effect that this guidance will have on its consolidated financial position, results of operations and cash flows.

     Fees Paid to the Federal Government by Pharmaceutical Manufacturers. In December 2010, the FASB ratified a consensus of the Emerging Issues Task Force (“EITF”) related to an annual fee to be paid to the federal government by pharmaceutical manufacturers as mandated by the Patient Protection and Affordable Care Act as amended by the Health Care and Education Reconciliation Act. This consensus requires the liability related to the annual fee to be estimated and recorded in full upon the first qualifying sale with a corresponding deferred cost that is amortized to expense generally using a straight-line method of allocation over the calendar year that it is payable. This guidance is effective for calendar years beginning after December 31, 2010, when the fee initially became effective. The Company adopted this guidance effective January 1, 2011. The adoption of this guidance did not have a material impact on the Company’s consolidated financial position, results of operations and cash flows.

     Milestone Method of Revenue Recognition. In March 2010, the FASB ratified a consensus of the EITF related to the milestone method of revenue recognition. The consensus codifies a method of revenue recognition that has been common practice. Under this method, contingent consideration from research and development activities that is earned upon the achievement of a substantive milestone is recognized in its entirety in the period in which the milestone is achieved. This guidance is effective for annual periods beginning on or after June 15, 2010 but may be early adopted as of the beginning of an annual period. The Company adopted this guidance effective October 1, 2010. The adoption of this guidance did not have a material impact on the Company’s consolidated financial position, results of operations and cash flows.

     Multiple-Deliverable Revenue Arrangements. In September 2009, the FASB issued authoritative guidance regarding multiple-deliverable revenue arrangements. This guidance addresses how to measure and allocate consideration to one or more units of accounting. Specifically, the guidance requires that consideration be allocated among multiple deliverables based on relative selling prices. The guidance establishes a selling price hierarchy of (1) vendor-specific objective evidence, (2) third-party evidence and (3) estimated selling price. This guidance is

effective for annual periods beginning on or after June 15, 2010 but may be early adopted as of the beginning of an annual period. The Company adopted this guidance effective October 1, 2010. The adoption of this guidance did not have a material impact on the Company’s consolidated financial position, results of operations and cash flows.

3. FAIR VALUE OF MEASUREMENTS

     The Company measures the fair value of certain of its financial assets on a recurring basis. A fair value hierarchy is used to rank the quality and reliability of the information used to determine fair values. Financial assets and liabilities carried at fair value will be classified and disclosed in one of the following three categories:

	•		Level 1-Quoted prices in active markets for identical assets and liabilities.
	•		Level 2-Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets and liabilities, quoted prices in the markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.
	•		Level 3-Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

     As of June 30, 2011 and September 30, 2010, the Company’s cash equivalents held in money market mutual funds of approximately $54.2 million and $25.2 million, respectively, are all valued using quoted prices generated by market transactions involving identical assets, or Level 1, as defined by the fair value hierarchy noted above.

4. RESTRICTED INVESTMENTS IN MARKETABLE SECURITIES

     Restricted investments in marketable securities at June 30, 2011 and September 30, 2010 consist of certificates of deposit, which are classified as held-to-maturity. At June 30, 2011 and September 30, 2010, the fair value of these investments approximated their cost basis.

     At June 30, 2011, restricted investments in marketable securities totaling approximately $1.6 million consist of three certificates of deposit and are related to irrevocable standby letters of credit connected to fleet rentals and two office leases with expiration dates in 2013 and 2016, and are classified as non-current assets. The certificates of deposit related to fleet rentals and the office lease expiring in 2016 automatically renew annually and the certificate of deposit related to the office lease that expires in 2013 renews automatically every 30 days.

     Restricted investments in marketable securities also consist of two certificates of deposit totaling $617,100 and are related to the Company’s corporate credit card agreement and an irrevocable standby letter of credit connected to the short-term portion of an office lease with an expiration date in 2013, and are classified as current assets. The certificate of deposit related to the Company’s credit card agreement automatically renews every three months and the certificate of deposit related to the office lease renews automatically every 30 days.

     At September 30, 2010, restricted investments in marketable securities totaling $401,550 consisted of an investment certificate of deposit that automatically renewed every 30 days and was related to a letter of credit connected to an office lease with an expiration date in 2013 and was classified as a non-current asset. Restricted investments in marketable securities also consisted of a $200,000 certificate of deposit that renewed every three months and was related to the Company’s corporate credit card agreement and was classified as a current asset.

5. INVENTORIES

     Inventories are comprised of NUEDEXTA product and the active pharmaceutical ingredients of NUEDEXTA, dextromethorphan and quinidine, as well as the active pharmaceutical ingredient docosanol.

     The composition of inventories as of June 30, 2011 and September 30, 2010 is as follows:

		June 30,				September 30,
		2011				2010
						(audited)
Raw materials		$	866,754			$	554,465
Work in progress			—				326,370
Finished goods			191,457				—
Inventories subject to return			8,237				—
Total inventory, net			1,066,448				880,835
Less: current portion			(700,562	)			(652,628	)
Non-current portion		$	365,886			$	228,207

     The amount classified as non-current inventories is comprised of the raw material components for NUEDEXTA, dextromethorphan and quinidine, which will be used in the manufacture of NUEDEXTA capsules in the future. Included in finished goods inventory is NUEDEXTA that was manufactured in 2010 to obtain FDA approval. This product is currently being sold to wholesalers and is scheduled to expire in 2012. Wholesalers generally will not purchase product that is within 12 months of expiration. As such, the Company recorded an inventory write-down of approximately $82,000 for the nine months ended June 30, 2011, for the estimated amount of product that may not be shipped due to short-dating. Included in the three and nine months ended June 30, 2010 is a write-down of docosanol inventory of $80,000.

     As of June 30, 2011 and September 30, 2010, raw materials represent gross raw materials of approximately $1.6 million and $1.3 million, respectively, offset by inventory reserves of approximately $699,000 for each period. Inventory write-downs may be taken in the future as the Company continues to assess inventory on a periodic basis or due to potential changes in the operating procedures of our contract manufacturers.

6. ACCRUED EXPENSES AND OTHER LIABILITIES

Accrued expenses and other liabilities are as follows:

		June 30,				September 30,
		2011				2010

7. NET DEFERRED REVENUES

     The following table sets forth as of June 30, 2011 the deferred royalty revenue balances for the Company’s sale of future Abreva^® royalty rights to Drug Royalty USA and NUEDEXTA product shipments:

		NUEDEXTA
		Product				Drug Royalty
		Shipments, Net				USA Agreement				Total
Net deferred revenues as of October 1, 2010		$	—			$	8,476,831			$	8,476,831
Changes during the period:
Shipments, net.			4,065,512				—				4,065,512
Recognized as revenues during the period			(2,481,622	)			(1,662,392	)			(4,144,014	)
Net deferred revenues as of June 30, 2011 (1)		$	1,583,890			$	6,814,439			$	8,398,329
Classified and reported as:
Current portion of deferred revenues		$	1,583,890			$	2,087,226			$	3,671,116
Deferred revenues, net of current portion			—				4,727,213				4,727,213
Total net deferred revenues		$	1,583,890			$	6,814,439			$	8,398,329

     NUEDEXTA Product — The amount of deferred revenue from NUEDEXTA product shipments is shown net of estimated prompt-pay discounts and wholesaler fees based on wholesaler purchases. The amount that ultimately will be recognized as net product sales in the Company’s consolidated financial statements may be different due to other discounts and allowances, including, but not limited to, wholesaler fees based on wholesaler shipments, rebates, chargebacks and co-pay assistance. See Note 2, “Significant Accounting Policies — Revenue recognition — Product Sales — NUEDEXTA” for further discussion.

     Drug Royalty Agreement — In November 2002, the Company sold to Drug Royalty USA an undivided interest in the Company’s rights to receive future Abreva royalties under the license agreement with GlaxoSmithKline for $24.1 million (the “Drug Royalty Agreement” and the “GSK License Agreement,” respectively). Under the Drug Royalty Agreement, Drug Royalty USA has the right to receive royalties from GlaxoSmithKline on sales of Abreva until December 2013. The Company retained the right to receive 50% of all royalties (a net of 4%) under the GSK License Agreement for annual net sales of Abreva in the U.S. and Canada in excess of $62 million.

     Revenues are recognized when earned, collection is reasonably assured and no additional performance of services is required. The Company classified the proceeds received from Drug Royalty USA as deferred revenue, to be recognized as revenue over the life of the license agreement, because of the Company’s continuing involvement over the term of the Drug Royalty Agreement. Such continuing involvement includes overseeing the performance of

GlaxoSmithKline and its compliance with the covenants in the GSK License Agreement, monitoring patent infringement, adverse claims or litigation involving Abreva, and undertaking to find a new license partner in the event that GlaxoSmithKline terminates the agreement. The Drug Royalty Agreement contains both covenants and events of default that require such performance on the Company’s part. Therefore, nonperformance on the Company’s part could result in default of the arrangement, and could give rise to additional rights in favor of Drug Royalty USA under a separate security agreement with Drug Royalty USA, which could result in loss of the Company’s rights to share in future Abreva royalties if wholesale sales by GlaxoSmithKline exceed $62 million a year. Because of the Company’s continuing involvement, the Company recorded the net proceeds of the transaction as deferred revenue, which is being recognized as revenue using the “units-of-revenue method” over the life of the license agreement. Based on a review of the Company’s continuing involvement, the Company concluded that the sale proceeds did not meet any of the rebuttable presumptions that would require classification of the proceeds as debt.

8. COMPUTATION OF NET LOSS PER COMMON SHARE

     Basic net loss per common share is computed by dividing net loss by the weighted-average number of common shares outstanding during the period, excluding restricted stock that has been issued but is not yet vested. Diluted net loss per common share is computed by dividing net loss by the weighted-average number of common shares outstanding during the period plus additional weighted-average common equivalent shares outstanding during the period. Common equivalent shares result from the assumed exercise of outstanding stock options and warrants (the proceeds of which are then presumed to have been used to repurchase outstanding stock using the treasury stock method) and the vesting of restricted shares of common stock. In loss periods, certain of the common equivalent shares are excluded from the computation of diluted net loss per share, because their effect would have been anti-dilutive.

     For the nine month periods ended June 30, 2011 and 2010, the following options and warrants to purchase shares of common stock and restricted stock units were excluded from the computation of diluted net loss per share, as the inclusion of such shares would be anti-dilutive:

		2011				2010
Stock options			7,908,679				6,257,087
Stock warrants			6,155,170				12,240,437
Restricted stock units (1)			1,798,812				2,050,644

9. STOCKHOLDERS’ EQUITY

     On July 30, 2009, the Company entered into a Controlled Equity Offering Sales Agreement (the “Sales Agreement”) with Cantor Fitzgerald & Co. (“Cantor”), providing for the sale of up to 12,500,000 shares of common stock from time to time into the open market at prevailing prices. Pursuant to the Sales Agreement, sales of common stock will be made in such quantities and on such minimum price terms as the Company may set from time to time. During the nine month period ended June 30, 2011, the Company issued 1,235,000 shares of common stock under the Sales Agreement raising proceeds of approximately $5.3 million, net of offering costs, including commissions. As of June 30, 2011, a total of 7,594,510 shares of common stock have been issued under the Sales Agreement at an average price of $2.83 per share raising gross proceeds of approximately $21.5 million ($20.6 million, net of offering costs, including commissions). No shares have been sold under this facility since November 2010.

     In November 2010, the Company completed a common stock offering raising $88.0 million in gross proceeds and approximately $83.0 million in net proceeds to the Company after deducting underwriting discounts, commissions and offering expenses. In connection with the offering, 20 million shares of common stock were sold at a public offering price of $4.40 per share. The Company intends to use the net proceeds for operating expenses. In addition, the net proceeds may be used for further clinical, regulatory and commercial development of AVP-923, as well as business development activities.

     During the nine months ended June 30, 2011, the Company received proceeds of approximately $8.7 million from the exercise of warrants to purchase 6,085,267 shares of the Company’s common stock. The warrants had been issued in connection with the Company’s registered securities offering in April 2008 at an exercise price of $1.43 per share. As of June 30, 2011, warrants to purchase 6,155,170 shares of the Company’s common stock at a weighted-average exercise price per share of $1.43 remained outstanding, all of which are exercisable. The warrants outstanding at June 30, 2011, are callable by the Company when the Company’s stock price reaches 400% of the warrant’s exercisable price for at least twenty trading days during any consecutive sixty day period.

     During the nine month period ended June 30, 2011, the Company issued 252,342 shares of common stock in connection with the vesting of restricted stock units. During the nine months ended June 30, 2011, restricted stock unit awards for a total of 209,093 shares awarded to directors vested, but the issuance and delivery of these shares are deferred until the director resigns.

10. EMPLOYEE EQUITY INCENTIVE PLANS

     The Company currently has five equity incentive plans under which awards are outstanding (the “Plans”), two of which are currently in active use as described below. The Plans are: the 2005 Equity Incentive Plan (the “2005 Plan”), the 2003 Equity Incentive Plan (the “2003 Plan”), the 2000 Stock Option Plan (the “2000 Plan”), the 1998 Stock Option Plan (the “1998 Plan”) and the 1994 Stock Option Plan (the “1994 Plan”), which are described in the Company’s Annual Report on Form 10-K for the year ended September 30, 2010. All of the Plans were approved by the stockholders, except for the 2003 Equity Incentive Plan, which was approved solely by the Board of Directors. Share-based awards are subject to terms and conditions established by the Compensation Committee of the Company’s Board of Directors. The Company’s policy is to issue new common shares upon the exercise of stock options, conversion of restricted share units or purchase of restricted stock.

     During the nine month period ended June 30, 2011, the Company granted share-based awards under the 2003 Plan and the 2005 Plan. During the nine month period ended June 30, 2010, the Company granted share-based awards under the 2003 Plan. Under the 2003 Plan and 2005 Plan, options to purchase shares, restricted stock units, restricted stock and other share-based awards may be granted to the Company’s directors, employees and consultants. Pursuant to the provisions of annual increases of the 2003 Plan and the 2005 Plan, the number of authorized shares of common stock for issuance under the 2003 Plan and the 2005 Plan increased 4,255,003 effective February 7, 2011 and 325,000 effective November 10, 2010, respectively. Under the Plans, as of June 30, 2011, the Company had an aggregate of 18,190,028 shares of its common stock reserved for future issuance. Of those shares, 9,707,491 were subject to outstanding options and other awards and 8,482,537 shares were available for future grants of share-based awards. As of June 30, 2011, 120,000 restricted stock units were outstanding to consultants. The Company may also, from time to time, issue share-based awards outside of the Plans to the extent permitted by NASDAQ rules. As of June 30, 2011, there were no options to purchase shares of the Company’s common stock that were issued outside of the Plans (inducement option grants) outstanding. None of the share-based awards are classified as a liability as of June 30, 2011.

     Stock Options. Stock options are granted with an exercise price equal to the current market price of the Company’s common stock at the grant date and have 10-year contractual terms. For option grants to employees, generally 25% of the option shares vest and become exercisable on the first anniversary of the grant date and the remaining 75% of the option shares vest and become exercisable quarterly in equal installments thereafter over three years; for option grants to non-employee directors, one-third of the option shares vest and become exercisable on the first anniversary of the grant date and the remaining two-thirds of the option shares vest and become exercisable daily or quarterly in equal installments thereafter over two years; and for certain option grants to non-employee directors, options have been granted as fully vested and exercisable at the date of grant. Certain option awards provide for accelerated vesting if there is a change in control (as defined in the Plans).

     Summaries of stock options outstanding and changes during the nine month period ended June 30, 2011 are presented below.

										Weighted Average
						Weighted Average				Remaining				Aggregate
		Number				Exercise Price per				Contractual Term				Intrinsic
		of Shares				Share				(In Years)				Value
Outstanding October 1, 2010			6,364,265			$	1.69
Granted			2,247,700			$	4.06
Exercised			(649,296	)		$	0.74
Forfeited			(53,990	)		$	4.30
Outstanding June 30, 2011			7,908,679			$	2.43				8.1			$	11,238,525
Vested and expected to vest in the future, June 30, 2011 (1)			7,417,938			$	2.40				8.0			$	10,811,714
Exercisable, June 30, 2011			2,703,944			$	2.27				7.1			$	5,259,731

     The weighted average grant-date fair value of options granted during the nine month periods ended June 30, 2011 and 2010 was $3.32 and $1.51 per share, respectively. The total intrinsic value of options exercised during the nine month periods ended June 30, 2011 and 2010 was approximately $2.2 million and $58,000, respectively, based on the differences in market prices on the dates of exercise and the option exercise prices. As of June 30, 2011, the total unrecognized compensation cost related to unvested options was approximately $9.6 million which is expected to be recognized over the weighted-average period of 2.7 years, based on the vesting schedules. No tax benefit was realized for the tax deductions from option exercise of the share-based payment arrangements in the nine month periods ended June 30, 2011 and 2010.

     The fair value of each option award is estimated on the date of grant using the Black-Scholes model, which uses the assumptions noted in the following table. Expected volatilities are based on historical volatility of the Company’s common stock and other factors. The expected term of options granted is based on analyses of historical employee termination rates and option exercises. The risk-free interest rate is based on the U.S. Treasury yield for a period consistent with the expected term of the option in effect at the time of the grant.

     Assumptions used in the Black-Scholes model for options granted during the nine month period ended June 30, 2011 were as follows:

Expected volatility			104% - 108	%
Weighted-average volatility			108	%
Expected term in years			5.8
Risk-fee interest rate (zero coupon U.S. Treasury Note)			1.5% - 2.5	%
Expected dividend yield			0	%

     The following table summarizes information concerning outstanding and exercisable stock options as of June 30, 2011:

		Options Outstanding												Options Exercisable
						Weighted
						Average				Weighted								Weighted
						Remaining				Average								Average

     Restricted stock units (“RSU”). RSUs granted to employees generally vest based on three years of continuous service from the date of grant. RSUs granted to non-employee directors generally vest over the term of one year from the grant date and are not released until the awardee’s termination of service. In fiscal 2010, vesting for non-employee director grants was amended to allow for accelerated vesting of RSUs in the case of a non-employee director’s resignation where either: (i) he/she has served for at least four years as a member of the Board and is in good standing at the time of resignation, or (ii) he/she resigns for reasons related to health or family matters and is otherwise in good standing at the time of resignation.

     The following table summarizes the RSU activities for the nine months ended June 30, 2011:

						Weighted Average
						Grant Date
		Number of Shares				Fair Value
Unvested, October 1, 2010			521,203			$	1.78
Granted			371,813			$	4.12
Vested			(461,504	)		$	2.01
Unvested, June 30, 2011.			431,512			$	3.56

     The grant-date fair value of RSUs granted during the nine month periods ended June 30, 2011 and 2010 was approximately $1.5 million and $960,000, respectively. As of June 30, 2011, the total unrecognized compensation cost related to unvested shares was approximately $1.1 million which is expected to be recognized over a weighted-average period of 1.0 years, based on the vesting schedules. The Company received no cash from restricted stock awards under all share-based payment arrangements during the nine month periods ended June 30, 2011 and 2010.

     At June 30, 2011, there were 1,367,231 shares of restricted stock with a weighted-average grant date fair value of $1.70 per share awarded to directors that have vested but are still restricted until the director resigns.

     In December 2010, the Company awarded performance-based RSUs (“Performance RSUs”) to purchase up to 166,813 shares of the Company’s common stock. The grant date fair value of these awards was $4.18 per share. The RSUs have a performance goal that determines the actual number of shares to be awarded up to 166,813 shares. If the goal is met by the target date, no shares are forfeited. If the goal is met within two months after the target date, 25% of the shares will be forfeited and if the goal is not met within two months after the target date, all shares will be forfeited. As of June 30, 2011, the performance goal had been achieved and no shares were forfeited. The shares vest 50% on the first anniversary of the grant date and the remaining 50% on the second anniversary of the grant date.

     In November 2009, the Company’s compensation committee approved a modification to the vesting schedule of RSUs originally granted on December 4, 2007 (“Modified Awards”). The Modified Awards originally were to vest 50% upon the earlier of the completion of a Company milestone or December 4, 2010, and the remaining 50% on December 4, 2010. The awards’ vesting was modified to vest equally over two specified dates, March 15, 2010 and

December 4, 2010. The Modified Awards were for an aggregate of 480,785 RSUs held by eight employees, including officers. The modification did not change the probability of vesting and did not result in any incremental share-based compensation. At the date of modification, no RSUs were vested and the then remaining unamortized share-based compensation expense was amortized over the remaining vesting periods of the Modified Awards.

     During the nine month period ended June 30, 2010, the Company awarded an RSU representing the right to acquire a total of 120,000 shares of common stock to a non-employee. The grant date fair value of this award was $2.08 per share. The restricted stock units vest on the earlier of October 15, 2011 or the completion of a performance target, and are re-measured at each balance sheet date until vested.

11. COMMITMENTS AND CONTINGENCIES

     Center for Neurologic Study (“CNS”) — The Company holds the exclusive worldwide marketing rights to NUEDEXTA for certain indications pursuant to an exclusive license agreement with CNS.

     In fiscal 2005, the Company paid $75,000 to CNS under the agreement for the submission of the new drug application (“NDA”) for the PBA indication. Upon FDA approval of NUEDEXTA for the treatment of PBA in the first quarter of fiscal 2011, the Company paid an additional $75,000 milestone. In addition, the Company is obligated to pay CNS a royalty ranging from approximately 5% to 8% of net GAAP revenue generated by sales of NUEDEXTA. During the nine month period ended June 30, 2011, the Company recorded royalties of approximately $199,000 related to NUEDEXTA product shipments. Of this amount, approximately $122,000 is recorded to cost of product sales in the condensed consolidated statements of operations for the nine months ended June 30, 2011, and the remaining $77,000 represents deferred cost of product sales and is recorded to other current assets in the condensed consolidated balance sheet at June 30, 2011. Under certain circumstances, the Company may have the obligation to pay CNS a portion of net revenues received if it sublicenses NUEDEXTA to a third party.

     Under the agreement with CNS, the Company is required to make payments on achievements of up to a maximum of ten milestones, based upon five specific medical indications. Maximum payments for these milestone payments could total approximately $1.1 million if the Company pursued the development of NUEDEXTA for all five of the licensed indications. In general, individual milestones range from $75,000 to $125,000 for each accepted NDA filing and a similar amount for each approved NDA in addition to the royalty discussed above on net GAAP revenues. The Company does not have the obligation to develop additional indications under the CNS license agreement.

     Lease Commitment — On February 1, 2011, the Company entered into a lease agreement for approximately 30,000 square feet of office space commencing on July 1, 2011, for an initial lease term of 65 months. The lease has scheduled increases each year. The aggregate minimum payments over the initial lease term of the lease are expected to be approximately $3.8 million.

     Legal Contingencies — In June 2011, the FDA reported that an Abbreviated New Drug Application (ANDA) for a generic version of NUEDEXTA capsules was submitted on March 7, 2011. The Company has since received Paragraph IV certification notices from four separate companies contending that the Company’s patents listed in the Orange Book (U.S. Patents 7,659,282 and RE 38,115, which expire in August 2026 and January 2016, respectively) are invalid, unenforceable and/or will not be infringed by the manufacture, use, or sale of a generic form of NUEDEXTA. The Company intends to vigorously enforce its intellectual property rights relating to NUEDEXTA.

     In the ordinary course of business, the Company may face various claims brought by third parties and it may, from time to time, make claims or take legal actions to assert the Company’s rights, including intellectual property rights as well as claims relating to employment and the safety or efficacy of its products. Any of these claims could subject the Company to costly litigation and, while the Company generally believes that it has adequate insurance to cover many different types of liabilities, the Company’s insurance carriers may deny coverage or the Company’s policy limits may be inadequate to fully satisfy any damage awards or settlements. If this were to happen, the payment of any such awards could have a material adverse effect on the Company’s operations, cash flows and financial position. Additionally, any such claims, whether or not successful, could damage the Company’s reputation and business. Management believes the outcomes of currently pending claims and lawsuits are not likely to have a material effect on the Company’s operations or financial position.

     In May 2010, the Company received proceeds from a legal settlement in the amount of approximately $390,000. The proceeds were recorded as Other, net under Other Income (Expense) in the condensed consolidated statement of operations in the third quarter of fiscal 2010.

     In addition, it is possible that the Company could incur termination fees and penalties if it elected to terminate contracts with certain vendors.

     Guarantees and Indemnities — The Company indemnifies its directors and officers to the maximum extent permitted under the laws of the State of Delaware, and various lessors in connection with facility leases for certain claims arising from such facilities or leases. Additionally, the Company periodically enters into contracts that contain indemnification obligations, including contracts for the purchase and sale of assets, wholesale distribution agreements, clinical trials, pre-clinical development work and securities offerings. These indemnification obligations provide the contracting parties with the contractual right to have the Company pay for the costs associated with the defense and settlement of certain claims, typically in circumstances where the Company has failed to meet its contractual performance obligations in some fashion.

     The maximum amount of potential future payments under such indemnifications is not determinable. The Company has not incurred significant costs related to these guarantees and indemnifications, and no liability has been recorded in the condensed consolidated financial statements for guarantees and indemnifications as of June 30, 2011.

12. SEGMENT INFORMATION

     The Company operates its business on the basis of a single reportable segment, which is the business of discovery, development and commercialization of novel therapeutics for chronic diseases. The Company’s chief operating decision-maker is the Chief Executive Officer, who evaluates the Company as a single operating segment.

     The Company categorizes revenues by geographic area based on selling location. All the Company’s operations are currently located in the United States; therefore, total revenues for the three and nine month periods ended June 30, 2011 and 2010 are attributed to the United States. All long-lived assets at June 30, 2011 and September 30, 2010 are located in the United States.

     For the three month periods ended June 30, 2011 and 2010, the revenues from prior sale of rights to royalties under the GSK license agreement were 22% and 100% of total net revenues, respectively.

     For the nine month periods ended June 30, 2011 and 2010, the revenues from prior sale of rights to royalties under the GSK license agreement were 49% and 83% of total net revenues, respectively. For the nine month periods ended June 30, 2011 and 2010, royalty revenues from Azur were 9% and 17% of total net revenues, respectively.

13. SUBSEQUENT EVENTS

     The Company has evaluated subsequent events through the filing date of this Form 10-Q, and determined that no subsequent events have occurred that would require recognition in the condensed consolidated financial statements or disclosure in the notes thereto other than discussed in the accompanying notes.

EXECUTIVE OVERVIEW

     Avanir is a pharmaceutical company focused on acquiring, developing and commercializing novel therapeutic products for the treatment of central nervous system disorders. In October 2010, the U.S. Food and Drug Administration (“FDA”) approved NUEDEXTA^® (formally referred to as AVP-923 during clinical development), a unique proprietary combination of dextromethorphan (“DM”)/quinidine (“Q”), for the treatment of pseudobulbar affect (“PBA”). We commenced promotion of NUEDEXTA in the United States in February 2011 and we are currently pursuing approval of NUEDEXTA in Europe.

     We are also studying AVP-923 for use in different types of neuropathic pain. We have filed an Investigational New Drug application (“IND”) with the FDA to begin a large Phase II clinical trial of AVP-923, an investigational drug for the treatment of central neuropathic pain in patients with multiple sclerosis. The FDA has accepted the proposed clinical investigational plan included in the submission and we plan to enroll the first patient before the end of calendar 2011.

     AVP-923 has also successfully completed a Phase III trial for the treatment of patients with diabetic peripheral neuropathic pain (“DPN pain”).

     In addition to our focus on products for the central nervous system, we also have partnered programs in other therapeutic areas which may generate future income. Our first commercialized product, docosanol 10% cream, (sold in the United States and Canada as Abreva^® by our marketing partner GlaxoSmithKline Consumer Healthcare) is the only over-the-counter treatment for cold sores that has been approved by the FDA. In 2008, we licensed all our monoclonal antibodies and remain eligible to receive milestone payments and royalties related to the sale of these assets.

     NUEDEXTA for the Treatment of PBA

     NUEDEXTA is the first and only FDA-approved treatment for PBA. PBA occurs secondary to a variety of otherwise unrelated neurological conditions, and is characterized by involuntary, sudden, and frequent episodes of laughing and/or crying. PBA episodes typically occur out of proportion or incongruent to the patient’s underlying emotional state.

     NUEDEXTA is an innovative combination of two well-characterized components: dextromethorphan hydrobromide (20 mg), the active ingredient in the central nervous system, and quinidine sulfate (10 mg), a metabolic inhibitor enabling therapeutic dextromethorphan concentrations. NUEDEXTA acts on sigma-1 and N-Methyl-D-aspartic acid, or NMDA, receptors in the brain, although the mechanism by which NUEDEXTA exerts therapeutic effects in patients with PBA is unknown.

     Studies to support the effectiveness of NUEDEXTA in PBA were performed in patients with amyotrophic lateral sclerosis, or ALS, and multiple sclerosis, or MS. NUEDEXTA has not been shown to be safe and effective in other types of emotional lability that can commonly occur, for example, in Alzheimer’s disease and other dementias. The primary outcome measure, laughing and crying episodes, was significantly lower in the NUEDEXTA cohort compared to placebo. The secondary outcome measure, the Center for Neurologic Studies Lability Scale (CNS-LS), demonstrated a significantly greater mean decrease in CNS-LS score from baseline for the NUEDEXTA cohort compared to placebo.

     AVP-923 for the Potential Treatment of Neuropathic Pain

     AVP-923 for the treatment of MS-related pain

     Multiple Sclerosis (“MS”) is one of the most frequent chronic disease generating neurologic disabilities in young adults. Among the many symptoms and types of disabilities associated with MS, chronic pain has a significant impact on the daily life of patients with this disease.

     Several distinct pain conditions associated with multiple sclerosis (MS) have been characterized in various literature, including optic neuritis, headache, musculoskeletal pain (which includes painful tonic spasms, back pain and muscle spasms) and central neuropathic pain (which includes extremity pain, trigeminal neuralgia and Lhermitte’s sign). While the specific pain mechanisms associated with each condition have not been fully identified, it is believed that neuropathic pain results from neurologic damage caused by demyelinating lesions. Pain is a common symptom experienced by many MS patients and, in particular, approximately 30% of MS patients experience central neuropathic pain during the course of the disease.

     In September 2009, we reported on secondary efficacy endpoints from the double-blind phase of the AVP-923 STAR trial in PBA, including an endpoint measuring reduction of MS-related pain. AVP-923 30/10 mg demonstrated statistically significant decrease in pain scores compared to placebo in the subset of MS patients with moderate-to-severe pain. Based on these results, we filed an IND application with the FDA to begin a Phase II clinical trial of AVP-923 for the treatment of central neuropathic pain in patients with MS. The FDA has accepted the proposed clinical investigational plan included in the submission and we plan to enroll the first patient before the end of calendar 2011.

     The objectives of the study are to evaluate the safety, tolerability, and efficacy of three dose levels of AVP-923 capsules for the treatment of central neuropathic pain in a population of patients with MS. The trial is a multicenter, randomized, double-blind, placebo-controlled, 4-arm parallel group study. Eligible patients will be randomized to receive one of the three dose levels of AVP-923 containing either 45mg DM/10mg Q, 30mg DM/10mg Q, 20mg DM/10mg Q or placebo, daily for 12 weeks. The primary efficacy endpoint is the Pain Rating Scale obtained from daily patient diaries. Secondary endpoints include measure of fatigue, impact of MS on daily life, sleep quality, cognition and depression. Safety will be assessed by monitoring adverse events, clinical laboratory tests, ECGs, physical examinations, and vital signs. We expect to enroll approximately 400 patients at 65 centers both in the U.S. and internationally.

     AVP-923 for the treatment of diabetic neuropathic pain

     Diabetic peripheral neuropathic pain (“DPN pain”), which arises from nerve injury, can result in a chronic and debilitating form of pain that has historically been poorly diagnosed and treated. It is often described as burning, tingling, stabbing, or pins and needles in the feet, legs, hands or arms. An estimated 3.5 million people in the United States experience DPN pain according to the American Diabetes Association. DPN pain currently is most commonly treated with antidepressants, anticonvulsants, opioid analgesics and local anesthetics. Most of these treatments have limited effectiveness or undesirable side effects resulting in a high degree of unmet medical need. The neuropathic pain market is continuing to grow rapidly, and in 2006, was estimated to be worth $2.6 billion in sales among the seven largest markets, consisting of the United States, Japan, France, Germany, Italy, Spain and the United Kingdom.

     Avanir has successfully completed a Phase III clinical trial for AVP-923 in the treatment of patients with DPN pain. In April 2007, we announced positive top-line data from our first Phase III clinical trial of AVP-923 for the treatment of patients with DPN pain. The most commonly reported adverse events from this Phase III study were

dizziness, nausea, diarrhea, fatigue and somnolence, which were mild to moderate in nature. We are continuing to evaluate our options for this program and next steps.

Docosanol 10% Cream — Cold Sore Treatment

     Docosanol 10% cream is a topical treatment for cold sores. In 2000, we received FDA approval for marketing docosanol 10% cream as an over-the-counter product. Since that time, docosanol 10% cream has been approved by regulatory agencies in Asia, North America, and Europe. In March 2000, we granted a subsidiary of GlaxoSmithKline, SB Pharmco Puerto Rico, Inc. (“GSK”), the exclusive rights under a license to market docosanol 10% cream in the United States and Canada (“GSK License Agreement”). GSK markets the product under the name Abreva^® in these markets. Under the terms of the GSK License Agreement, GSK is responsible for all sales and marketing activities and the manufacturing and distribution of docosanol 10% cream. Under the GSK license agreement, we received a total of $25 million in milestone payments from GSK and we were entitled to receive an 8% royalty on net sales of Abreva by GSK.

     In November 2002, we sold to Drug Royalty USA an undivided interest in our rights to receive future Abreva royalties under the GSK License Agreement for $24.1 million (the “Drug Royalty Agreement”). Under the Drug Royalty Agreement, Drug Royalty USA has the right to receive royalties from GSK on sales of Abreva until December 2013. We retained the right to receive 50% of all royalties (a net of 4%) under the GSK License Agreement for annual net sales of Abreva in the U.S. and Canada in excess of $62 million. From the effective date of the GSK License Agreement up to the 2002 sale of our royalty rights to Drug Royalty USA, Inc. (“DRC”) we received a total of approximately $5.9 million in royalty payments from GSK attributed to the 8% royalty on net sales by GSK.

     Under the terms of our docosanol license agreements, our partners are generally responsible for all regulatory approvals, sales and marketing activities, and manufacturing and distribution of the product in the licensed territories. The terms of the license agreements typically provide for us to receive a data transfer fee, potential milestone payments and royalties on product sales. We purchase the active pharmaceutical ingredient (“API”), docosanol, from a large supplier in Western Europe and have, on occasion, sold material to our licensees. We currently store our API in the United States. Any material disruption in manufacturing could cause a delay in shipments and possible loss of sales.

     Xenerex Human Antibody Technology — Anthrax/Other Infectious Diseases

     In March 2008, we entered into an Asset Purchase and License Agreement with Emergent Biosolutions (“Emergent”) for the sale of our anthrax antibodies and license to use our proprietary Xenerex Technology platform, which was used to generate fully human antibodies to target antigens. Under the terms of the Agreement, we completed the remaining work under our NIH/NIAID grant (“NIH grant”) and transferred all materials to Emergent. Under the terms of the agreement, we are eligible to receive milestone payments and royalties on any product sales generated from this program. In connection with the sale of the anthrax antibody program, we also ceased all ongoing research and development work related to other infectious diseases on June 30, 2008.

     In September 2008, we entered into an Asset Purchase Agreement with a San Diego based biotechnology company for the sale of our non-anthrax related antibodies as well as the remaining equipment and supplies associated with the Xenerex Technology platform. In connection with this sale, we received an upfront payment and are eligible to receive future royalties on potential product sales, if any.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

     To understand our financial statements, it is important to understand our critical accounting policies and estimates. The preparation of our financial statements in conformity with accounting principles generally accepted in the United States of America requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Significant estimates and assumptions are required in the determination of revenue recognition and allowances, certain royalties and returns and losses. Significant estimates and assumptions are also required in the appropriateness of amounts recognized for inventories, income taxes, contingencies, and share-based compensation. Some of these judgments can be subjective and complex, and, consequently, actual results may differ from these estimates. For any given individual estimate or assumption made by us, there may also be other estimates or assumptions that are also reasonable. Although we believe that our estimates and assumptions are reasonable, they are based upon information available at the time the estimates and assumptions are made. Actual results may differ significantly from our estimates.

     A summary of significant accounting policies and a description of accounting policies that are considered critical may be found in Part II, Item 7 of our Annual Report on Form 10-K for the year ended September 30, 2010 in the “Critical Accounting Policies and Estimates” section, as updated and amended in Note 2 of the Notes to our Condensed Consolidated Financial Statements included herein.

RESULTS OF OPERATIONS

COMPARISON OF THREE MONTHS ENDED JUNE 30, 2011 AND 2010

Revenues

		Three months ended
		June 30,
		2011				2010				$ Change
REVENUES
Net product sales		$	1,932,235			$	—			$	1,932,235
Revenue from royalties			547,900				487,350				60,550
Total revenues		$	2,480,135			$	487,350			$	1,992,785

     Total net revenues were approximately $2.5 million for the three months ended June 30, 2011 compared to approximately $487,000 for the three months ended June 30, 2010. The increase in net revenues of approximately $2.0 million, or 409%, was primarily attributed to the product sales of NUEDEXTA which we began commercial promotion for in February 2011.

     Potential revenue-generating contracts that remained active as of June 30, 2011 include licensing revenue from our agreement with GSK, potential royalties from our agreements with Azur Pharma and Emergent Biosolutions, Inc. and modest potential revenue generated from various other licensing agreements. Partnering, licensing and research collaborations have been, and may continue to be, an important part of our business development strategy. We may continue to seek partnerships with pharmaceutical companies that can help fund our operations in exchange for sharing in the success of any licensed compounds or technologies.

Cost of Product Sales

     Cost of product sales were approximately $119,000 for the three months ended June 30, 2011 compared to $80,000 in the same period of fiscal 2010. The increase in cost of product sales is attributable to the sales of NUEDEXTA which we began commercial promotion for in February 2011, partially offset by a write-down of docosanol finished goods inventory of $80,000 in the three months ended June 30, 2010.

Operating Expenses

		Three months ended
		June 30,
		2011				2010				$ Change
OPERATING EXPENSES
Research and development		$	3,258,950			$	2,788,132			$	470,818
Selling, general and administrative			15,150,053				3,733,151				11,416,902
Total operating expenses		$	18,409,003			$	6,521,283			$	11,887,720

Research and Development Expenses

     Research and development expenses increased by approximately $471,000 from approximately $2.8 million in the third quarter of fiscal 2010 to approximately $3.3 million for the third quarter of fiscal 2011. The increase is primarily due to an increase in costs related to medical affairs activities for NUEDEXTA, partially offset by a decrease in clinical study costs related to the STAR trial that was completed in the third quarter fiscal 2010. We expect the quarterly expenditures for research and development expenses to increase from the third quarter of fiscal 2011 level as we continue to execute on our regulatory filing plan for NUEDEXTA in Europe and continue development of AVP-923 for treatment of central neuropathic pain in patients with MS. Medical affairs initiatives related to our marketed product, NUEDEXTA, are also included in research and development expenses and are expected to increase in the coming months.

Selling, General and Administrative Expenses

     Selling, general and administrative expenses increased by approximately $11.4 million from approximately $3.7 million for the third quarter of fiscal 2010 compared to approximately $15.2 million for the third quarter of fiscal 2011. The increase is primarily attributed to costs associated with preparation and execution of the commercial launch of NUEDEXTA, including increased personnel costs of approximately $6.1 million resulting from the hiring of a sales force and other key corporate and commercial headcount, which resulted in an increase of approximately 100 employees; increased marketing and market research costs of approximately $3.7 million; and increased other corporate costs of approximately $1.6 million. We expect an increase from third quarter fiscal 2011 levels in expenditures for selling, general and administrative expenses for the remainder of fiscal 2011 with our continued investments in the commercial launch of NUEDEXTA. Additionally, selling, general and administrative expense are expected to increase as we enforce our intellectual property rights relating to NUEDEXTA and continue the ongoing marketing of NUEDEXTA.

Share-Based Compensation

     Total share-based compensation expense in the three month periods ended June 30, 2011 and 2010 was approximately $957,000 and $583,000, respectively. Selling, general and administrative expense in the three month periods ended June 30, 2011 and 2010 includes share-based compensation expense of approximately $792,000 and $478,000, respectively. Research and development expense in the three month periods ended June 30, 2011 and 2010 includes share-based compensation expense of approximately $164,000 and $105,000, respectively. As of June 30, 2011, approximately $10.7 million of total unrecognized compensation costs related to nonvested options and awards is expected to be recognized over a weighted average period of 2.6 years. See Note 10, “Employee Equity Incentive Plans” in the Notes to Condensed Consolidated Financial Statements (Unaudited) for further discussion.

Other Income (Expense)

     For the three month period ended June 30, 2011, other income (expense) was approximately $17,000 expense, compared to approximately $392,000 income for the same period in the prior year. The Company recorded approximately $390,000 as Other Income in the three months ended June 30, 2010 in connection with a legal settlement. (See Note 11, “Commitments and Contingencies.”)

Net Loss

     Net loss was approximately $16.1 million, or $0.13 per share, in the three month period ended June 30, 2011 compared to a net loss of approximately $5.7 million, or $0.06 per share, for the three month period ended June 30, 2010.

COMPARISON OF NINE MONTHS ENDED JUNE 30, 2011 AND 2010

Revenues

Total revenues		$	5,735,125			$	2,966,778			$	2,768,347

     Total net revenues were approximately $5.7 million for the first nine months of fiscal 2011 compared to approximately $3.0 million for the first nine months of fiscal 2010. The increase in net revenues of approximately $2.8 million, or 93%, was primarily attributed to NUEDEXTA product sales of $2.4 million, which we commenced promotion for in February 2011. In addition, annual royalty revenue from our license agreement with GSK increased approximately $238,000.

Cost of Product Sales

     Cost of product sales were approximately $234,000 for the first nine months of fiscal 2011 compared to $80,000 in the same period of fiscal 2010. The increase in cost of product sales is attributable to the sales of NUEDEXTA which we began commercial promotion for in February 2011.

Total operating expenses		$	48,144,393			$	20,272,968			$	27,871,425

Research and Development Expenses

     Research and development expenses decreased by approximately $429,000 from approximately $10.1 million in the first nine months of fiscal 2010 to approximately $9.6 million for the first nine months of fiscal 2011. The decrease is primarily due to a decrease in clinical study costs related to the STAR trial that was completed in fiscal 2010, partially offset by an increase in costs related to regulatory and medical affairs activities for NUEDEXTA. We expect the quarterly expenditures for research and development expenses to increase from the third quarter of fiscal 2011 level as we continue to execute on our regulatory filing plan for NUEDEXTA in Europe and continue development of AVP-923 for treatment of central neuropathic pain in patients with MS. Medical affairs initiatives related to our marketed product, NUEDEXTA, are also included in research and development expenses and are expected to increase in the coming months.

Selling, General and Administrative Expenses

     Selling, general and administrative expenses increased by approximately $28.3 million from approximately $10.2 million for the first nine months of fiscal 2010 compared to approximately $38.5 million for the first nine months of fiscal 2011. The increase is primarily attributed to costs associated with preparation and execution of the commercial launch of NUEDEXTA, including increased personnel costs of approximately $15.4 million resulting from the hiring of a sales force and other key corporate and commercial headcount resulting in an increase of approximately 100 employees; increased marketing and market research costs of approximately $9.0 million; and increased other corporate costs of approximately $3.9 million. We expect an increase from third quarter fiscal 2011 levels in expenditures for selling, general and administrative expenses for the remainder of fiscal 2011 with our continued investments in the commercial launch of NUEDEXTA. Additionally, selling, general and administrative expense are expected to increase as we enforce our intellectual property rights relating to NUEDEXTA and continue the ongoing marketing of NUEDEXTA.

Share-Based Compensation

     Total share-based compensation expense in the nine month periods ended June 30, 2011 and 2010 was approximately $2.7 million and $1.9 million, respectively. Selling, general and administrative expense in the nine month periods ended June 30, 2011 and 2010 includes share-based compensation expense of approximately $2.3 million and $1.5 million, respectively. Research and development expense in the nine month periods ended June 30, 2011 and 2010 includes share-based compensation expense of approximately $463,000 and $434,000, respectively.

Other Income (Expense)

     For the nine month period ended June 30, 2011, other income (expense) was less than $1,000 expense, compared to approximately $401,000 income for the same period in the prior year. The Company recorded approximately $390,000 as Other Income in the nine months ended June 30, 2010 in connection with a legal settlement. (See Note 11, “Commitments and Contingencies.”)

Net Loss

     Net loss was approximately $42.6 million, or $0.36 per share, in the nine month period ended June 30, 2011 compared to a net loss of approximately $17.0 million, or $0.20 per share, for the nine month period ended June 30, 2010.

LIQUIDITY AND CAPITAL RESOURCES

     We assess our liquidity by our ability to fund current and future operations. Key factors in the management of our liquidity are: cash required to fund operating activities including expected operating losses and the levels of inventories, accounts payable and capital expenditures; the timing and extent of cash received from milestone payments under license agreements; ability to obtain adequate credit facilities; and financial flexibility to attract long-term equity capital on favorable terms. Historically, cash required to fund on-going business operations has been provided by financing activities and used to fund operations, working capital requirements and investing activities.

Net cash provided by or used in operating, investing and financing activities, are summarized in the table below.

		Nine months ended
		June 30,
		2011				2010				$ Change
Net cash used in operating activities		$	(42,473,047	)		$	(16,642,782	)		$	(25,830,265	)
Net cash used in investing activities			(2,500,775	)			(85,637	)			(2,415,138	)
Net cash provided by financing activities			97,499,372				26,566,484				70,932,888
Net increase in cash and cash equivalents		$	52,525,550			$	9,838,065			$	42,687,485

     Operating activities. Net cash used in operating activities was approximately $42.5 million for the nine months ended June 30, 2011 compared to approximately $16.6 million for the nine months ended June 30, 2010. The increase is primarily due to expenses related to our regulatory and commercial readiness activities including approximately $2.5 million of prepayments required for some large programs related to clinical trial costs and marketing activities.

     Investing activities. Net cash used in investing activities was approximately $2.5 million for the nine months ended June 30, 2011, compared to approximately $86,000 for the nine months ended June 30, 2010. The increase in cash used in investing activities was primarily related to investments in securities and an increase in the purchase of property and equipment to support the build-out of our commercial infrastructure and systems and general office needs.

     Financing activities. Net cash provided by financing activities was approximately $97.5 million for the nine months ended June 30, 2011 compared to approximately $26.6 million for the nine months ended June 30, 2010. In the first quarter of fiscal 2011, we raised approximately $83.0 million in proceeds, net of offering costs, including commissions, from our public offering and approximately $5.3 million in proceeds, net of offering costs, including commissions, from our at-the-market offering facility. Additionally, in the first nine months of fiscal 2011, we received proceeds of approximately $8.7 million from the exercise of warrants.

     In April 2009, we filed a shelf registration statement on Form S-3 with the SEC to sell an aggregate of up to $35.0 million in common stock, preferred stock, debt securities and warrants. As of June 30, 2011, approximately $13.5 million remains available on this shelf registration statement.

     On July 30, 2009 we entered into a financing facility with Cantor Fitzgerald & Co., providing for the sale of up to 12,500,000 shares of our common stock from time to time into the open market at prevailing prices. As of June 30, 2011, approximately 7.6 million shares of common stock had been sold under this facility for total gross proceeds of approximately $21.5 million. We may or may not sell additional shares under this facility, depending on the volume and price of our common stock, as well as our capital needs and potential alternative sources of capital, such as a development partner for AVP-923.

     In September 2009, we filed a shelf registration statement on Form S-3 with the SEC to sell an aggregate of up to $75.0 million in common stock, preferred stock, debt securities and warrants. On September 23, 2009, the registration statement was declared effective. Approximately $34.5 million remains available on this shelf registration statement following the offerings completed in May and November 2010 as discussed below.

     In May 2010, we sold an aggregate of 10,000,000 shares of our common stock in an underwritten public offering (the “Offering”). The shares in the Offering were sold at a public offering price of $2.75 per share, resulting in $27.5 million in gross offering proceeds and approximately $26.6 million in net proceeds us, after deducting underwriting discounts, commissions and offering expenses.

     In September 2010, we filed a shelf registration statement on Form S-3 with the SEC to sell an aggregate of up to $75.0 million in common stock, preferred stock, debt securities and warrants. Following the November 2010 offering discussed below, there were no funds remaining on this shelf registration statement.

     In November 2010, we completed an underwritten public offering of 20,000,000 shares of our common stock offered at a public offering price of $4.40 per share. Gross offering proceeds resulting from the offering were approximately $88.0 million, with net proceeds of approximately $83.0 million, after deducting offering discounts, costs and commissions.

     As of June 30, 2011 we have contractual obligations for long-term debt and operating lease obligations, as summarized in the table that follows.

		Payments Due by Period
						Less than												More than
		Total				1 year				1-3 years				3-5 years				5 years
Operating lease obligations (1)		$	5,640,124			$	1,470,966			$	2,189,578			$	1,625,599			$	353,981

     NUEDEXTA License Milestone Payments. We hold the exclusive worldwide marketing rights to NUEDEXTA for certain indications pursuant to an exclusive license agreement with the Center for Neurologic Study (“CNS”).

     We paid a $75,000 milestone upon FDA approval of NUEDEXTA for the treatment of PBA in the first quarter of fiscal 2011. In addition, we are obligated to pay CNS a royalty ranging from approximately 5% to 8% of net GAAP revenue generated by sales of NUEDEXTA. During the nine month period ended June 30, 2011, we recorded royalties of approximately $199,000 related to NUEDEXTA product shipments. Of this amount, approximately $122,000 is recorded to cost of product sales in the condensed consolidated statements of operations for the nine months ended June 30, 2011, and the remaining $77,000 represents deferred cost of product sales and is recorded to other current assets in the condensed consolidated balance sheet at June 30, 2011. Under certain circumstances, we may have the obligation to pay CNS a portion of net revenues received if we sublicense NUEDEXTA to a third party.

     Under the agreement with CNS, we are required to make payments on achievements of up to a maximum of ten milestones, based upon five specific clinical indications. Maximum payments for these milestone payments could total approximately $1.1 million if we pursued the development of NUEDEXTA for all five of the licensed indications. In general, individual milestones range from $75,000 to $125,000 for each accepted new drug application (“NDA”) and a similar amount for each approved NDA in addition to the royalty discussed above on net GAAP revenues. We do not have the obligation to develop additional indications under the CNS license agreement.

Off-Balance Sheet Arrangements

     We have no off-balance sheet arrangements.

Management Outlook

     We believe that cash and cash equivalents and restricted investments of approximately $93.5 million at June 30, 2011 will be sufficient to sustain our planned level of operations into the fourth quarter of calendar 2012. However, we cannot provide assurances that our planned level of expenditures will not change or will not result in the depletion of capital resources more rapidly than anticipated.

     For information regarding the risks associated with our need to raise capital to fund our ongoing and planned operations, please see Part II, Item 1A, “Risk Factors.”

Item 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

     As described below, we are exposed to market risks related to changes in interest rates. Because substantially all of our revenue, expenses and capital purchasing activities are transacted in U.S. dollars, our exposure to foreign currency exchange rates is immaterial. However, in the future we could face increasing exposure to foreign currency exchange rates as we expand international distribution of docosanol 10% cream and purchase additional services from outside the U.S. Until such time as we are faced with material amounts of foreign currency exchange rate risks, we do not plan to use derivative financial instruments, which can be used to hedge such risks. We will evaluate the use of derivative financial instruments to hedge our exposure as the needs and risks should arise.

Interest rate sensitivity

     The primary objective of our investments in securities is to preserve principal. We do not purchase financial instruments for trading purposes. Our investment portfolio consists primarily of cash fixed income instruments invested in government money market funds. We classify our restricted investments, which are primarily certificates of deposit, as of June 30, 2011 as held-to-maturity. These held-to-maturity securities are subject to interest rate risk. Based on our current low yield, any decrease in interest rates is not likely to have a material effect on interest income.

     As of June 30, 2011, approximately $54.2 million of our cash and cash equivalents were maintained in three separate money market mutual funds, and approximately $37.0 million of our cash and cash equivalents were maintained at three major financial institutions in the United States. At times, deposits held with the financial institution may exceed the amount of insurance provided by the Federal Deposit Insurance Corporation (“FDIC”), which provides deposit coverage with limits up to $250,000 per owner. In addition to the basic insurance deposit coverage, the FDIC is providing temporary unlimited coverage for noninterest-bearing transaction accounts from December 31, 2010 through December 31, 2012. At June 30, 2011, such uninsured deposits totaled approximately $90.7 million. Generally, these deposits may be redeemed upon demand and, therefore, are believed to bear minimal risk.

     Financial instruments that potentially subject us to concentrations of credit risk consist of cash and cash equivalents and trade receivables. However, we seek to mitigate the risk related to cash and cash equivalents by placing our cash and cash equivalents in various money market mutual funds and at financial institutions of high credit standing. To mitigate the risk related to trade receivables, we perform ongoing credit evaluations of our customers’ financial condition and would limit the amount of credit extended if necessary; however, we have usually required no collateral.

Item 4. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

     We carried out an evaluation, under the supervision and with the participation of our management, including our Chief Executive Officer and our Vice President, Finance (our principal financial and accounting officer), of the effectiveness of our “disclosure controls and procedures” as of the end of the period covered by this report, pursuant to Rules 13a-15(b) and 15d-15(b) under the Securities Exchange Act of 1934, as amended.

     In connection with that evaluation, our CEO and Vice President, Finance concluded that our disclosure controls and procedures were effective and designed to provide reasonable assurance that the information required to be disclosed is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission rules and forms as of June 30, 2011. For the purpose of this review, disclosure controls and procedures means controls and procedures designed to ensure that information required to be disclosed by the Company in the reports that we file or submit is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms. These disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by the Company in the reports that we file or submit is accumulated and communicated to management, including our principal executive officer

and principal financial and accounting officer, as appropriate, to allow timely decisions regarding required disclosure. In designing and evaluating the disclosure controls and procedures, our management recognized that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and our management necessarily was required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

Changes in Internal Controls over Financial Reporting

     There has been no change in our internal control over financial reporting (as defined in Rule 13a-15(f) under the Exchange Act) during our third quarter ended June 30, 2011, that has materially affected, or is reasonably likely to materially affect our internal control over financial reporting.

PART II OTHER INFORMATION

Item 1. LEGAL PROCEEDINGS

     In June 2011, the FDA reported that an Abbreviated New Drug Application (ANDA) for a generic version of NUEDEXTA capsules was submitted on March 7, 2011.We have since received Paragraph IV certification notices from four separate companies contending that our patents listed in the Orange Book (U.S. Patents 7,659,282 and RE 38,115, which expire in August 2026 and January 2016, respectively) are invalid, unenforceable and/or will not be infringed by the manufacture, use, or sale of a generic form of NUEDEXTA. We intend to vigorously enforce our intellectual property rights relating to NUEDEXTA.

     In the ordinary course of business, we may face various claims brought by third parties. Any of these claims could subject us to costly litigation. Management believes the outcome of currently identified claims and lawsuits will not have a material adverse effect on our financial condition or results of operations.

Item 1A. RISK FACTORS

     This Quarterly Report on Form 10-Q contains forward-looking information based on our current expectations. Because our actual results may differ materially from any forward-looking statements that we make or that are made on our behalf, this section includes a discussion of important factors that could affect our actual future results, including, but not limited to, our product sales, capital resources, commercial market estimates, safety of NUEDEXTA, future development efforts, patent protection, effects of healthcare reform, reliance on third parties, and other risks set forth below. We disclaim any intent to update forward-looking statements to reflect subsequent developments or actual results.

Risks Relating to Our Business

     Our near-term prospects are dependent on NUEDEXTA. If we are unable to successfully commercialize NUEDEXTA, including successfully maintaining adequate sales, marketing or distribution capabilities or entering into agreements with third parties to perform some of these functions, we will not be able to commercialize NUEDEXTA effectively and our ability to generate significant revenue or achieve profitability will be adversely affected.

     Although NUEDEXTA has been approved for marketing, our ability to generate significant revenue in the near to medium term is entirely dependent upon our ability to commercialize NUEDEXTA. As we continue to market NUEDEXTA, we may not be able to adequately build or maintain the necessary sales, marketing, supply chain management or reimbursement capabilities on our own or enter into arrangements with third parties to perform these functions in a timely manner or on acceptable terms. Additionally, maintaining sales, marketing and distribution capabilities may be more expensive than we anticipate, requiring us to divert capital from other intended purposes or preventing us from building our sales, marketing and distribution capabilities to the desired levels. To be successful we must continue to:

•

recruit and retain adequate numbers of effective sales personnel;

	•		effectively train our sales personnel on NUEDEXTA;
	•		establish and maintain successful sales and marketing and education programs for our targeted physicians;
	•		manage geographically dispersed sales and marketing operations;
	•		obtain adequate reimbursement for NUEDEXTA from a broad range of payors; and
	•		maintain and defend our patent protection and maintain regulatory exclusivity for NUEDEXTA.

     Supplying the market for NUEDEXTA requires us to manage relationships with an increasing number of collaborative partners, suppliers and third-party contractors. If we are unable to successfully establish and maintain the required infrastructure, either internally or through third parties, and successfully manage an increasing number of relationships, we will have difficulty growing our business. In addition, pharmacies, institutions and prescribers may rely on third-party medical information systems to interpret the NUEDEXTA approved product label and guide utilization of NUEDEXTA. If these information systems load incorrect information or misinterpret the approved product label, it may result in lower adoption or utilization than expected. For example, because NUEDEXTA contains quinidine, which is a known pro-arrhythmic drug at antiarrhythmic doses exceeding 600 mg per day, it is possible that medical information systems may incorrectly identify NUEDEXTA as contraindicated or otherwise inappropriate for a patient, even in situations where the risks are substantially less than indicated perceived.

     In addition, we may enter into co-promotion or out-licensing arrangements with other pharmaceutical or biotechnology partners where necessary to reach customers in domestic or foreign market segments and when deemed strategically and economically advisable. To the extent that we enter into co-promotion or other licensing arrangements, our product revenues are likely to be lower than if we directly marketed and sold NUEDEXTA, and some or all of the revenues we receive will depend upon the efforts of third parties, which may not be successful. If we are unable to develop and maintain adequate sales, marketing and distribution capabilities, independently or with others, we may not be able to generate significant product revenue or become profitable.

     We have a history of net losses and an accumulated deficit, and we may be unable to generate sufficient revenue to achieve or maintain profitability in the future.

     We have experienced significant net losses and negative cash flows from operations and we expect our negative cash flow from operations to continue until we are able to generate significant revenues from sales of NUEDEXTA. As of June 30, 2011, we had an accumulated deficit of approximately $347.3 million. We have incurred these losses principally from costs incurred in funding the research, development and clinical testing of our drug candidates, from our general and administrative expenses and from our efforts to commercialize NUEDEXTA. We may continue incurring net losses for the foreseeable future and we expect our operating losses to continue for at least the short term as we continue to market NUEDEXTA.

     Our ability to generate revenue and achieve profitability is dependent on our ability, alone or with partners, to successfully manufacture and market NUEDEXTA for the treatment of patients with PBA. We expect to continue to spend substantial amounts on the ongoing marketing of NUEDEXTA for PBA domestically, as well as seeking regulatory approvals for use of NUEDEXTA in other geographic markets and indications. As a result, we may never generate sufficient revenue from product sales to become profitable or generate positive cash flows.

     Certain of our key issued patents are currently being challenged and our pending patent applications may be denied. An adverse outcome in either case would adversely affect our ability to generate significant product revenue or become profitable.

     We have invested in an extensive patent portfolio and we rely substantially on the protection of our intellectual property through our ownership or control of issued patents and patent applications. The degree of patent protection that will ultimately be afforded to us in the U.S. and in other important markets remains uncertain and is dependent upon the scope of protection decided upon by the patent offices, courts and lawmakers in these countries. If we cannot prevent others from exploiting claims in our patent portfolio, we will not derive the benefit from it that we currently expect. Further, we may incur substantial expense from litigation to protect our patent portfolio.

     The validity, enforceability and scope of our core patents covering NUEDEXTA is currently being challenged as a result of recent ANDA filings from generic drug companies. The outcome of the current or any future challenges to the validity, enforceability or scope of our patent portfolio could significantly reduce revenues from NUEDEXTA and any future products. More broadly speaking, investors should be aware that the biopharmaceutical industry is highly competitive. Our ability to compete in this space involves various risks relating to our intellectual property, including:

	•		our patents covering NUEDEXTA may be found to be invalid and unenforceable or insufficiently broad to block the introduction of a generic form of NUEDEXTA;
	•		the claims in any of our pending patent applications may not be allowed and our patent applications may not be granted;
	•		competitors may develop similar or superior technologies independently, duplicate our technologies, or design around the patented aspects of our technologies;
	•		any of our issued patents may not provide us with significant competitive advantages; and
	•		we may not be able to secure additional worldwide intellectual property protection for our NUEDEXTA patent portfolio.

      An adverse outcome with respect to any of these risks could adversely affect our ability to generate significant product revenue or become profitable.

      If our products infringe the intellectual property rights of others, we may incur damages and be required to incur the expense of obtaining a license.

      Even if we successfully secure our intellectual property rights, third parties, including other biotechnology or pharmaceutical companies, may allege that our technology infringes on their rights Intellectual property litigation is costly, and even if we were to prevail in such a dispute, the cost of litigation could adversely affect our business, financial condition, and results of operations. Litigation is also time consuming and could divert management's attention and resources away from our operations and other activities. If we were to lose any litigation, in addition to any damages we would have to pay, we could be required to stop the infringing activity or obtain a license. Any required license might not be available to us on acceptable terms, or at all. Some licenses might be non-exclusive, and our competitors could have access to the same technology licensed to us. If we were to fail to obtain a required license or were unable to design around a competitor's patent, we would be unable to sell or continue to develop some of our products, which would have a material adverse effect on our business, financial condition and results of operations.

     We have received notice of four ANDA filings for NUEDEXTA submitted by generic drug companies. These ANDA filings assert that a generic form of NUEDEXTA would not infringe on our valid patent rights. As a result of these filings, we expect to be involved in costly and time consuming patent litigation against all four generic drug companies and, depending on the outcome of the litigation, we may face competition from lower cost generic or follow-on products in the near term.

     NUEDEXTA is approved under the provisions of the FDCA, which renders it susceptible to potential competition from generic manufacturers via the Hatch-Waxman Act and ANDA process. Generic manufacturers pursuing ANDA approval are not required to conduct costly and time-consuming clinical trials to establish the safety and efficacy of their products; rather, they are permitted to rely on the innovator’s data regarding safety and efficacy. Thus, generic manufacturers can sell their products at prices much lower than those charged by the innovative pharmaceutical or biotechnology companies who have incurred substantial expenses associated with the research and development of the drug product.

     The ANDA procedure includes provisions allowing generic manufacturers to challenge the innovator’s patent protection by submitting “Paragraph IV” certifications to the FDA in which the generic manufacturer claims that the innovator’s patent is invalid, unenforceable and/or will not be infringed by the manufacture, use, or sale of the generic product. A patent owner who receives a Paragraph IV certification may choose to sue the generic applicant for patent infringement. In recent years, generic manufacturers have used Paragraph IV certifications extensively to challenge the applicability of patents listed in the FDA’s Approved Drug Products List with Therapeutic Equivalence Evaluations, commonly referred to as the Orange Book, on a wide array of innovative therapeutic products. We expect this trend to continue and to implicate drug products with even relatively modest revenues.

     We have received Paragraph IV certification notices from four separate companies contending that our patents listed in the Orange Book (U.S. Patents 7,659,282 and RE 38,115, which expire in August 2026 and January 2016, respectively) are invalid, unenforceable and/or will not be infringed by the manufacture, use, or sale of a generic

form of NUEDEXTA. Although we intend to vigorously enforce our intellectual property rights relating to NUEDEXTA, there can be no assurance that we will prevail in our defense of our patent rights. Our existing patents could be invalidated, found unenforceable or found not to cover a generic form of NUEDEXTA.

     If an ANDA filer were to receive approval to sell a generic version of NUEDEXTA and/or prevail in any patent litigation, NUEDEXTA would become subject to increased competition and our revenue would be adversely affected.

     PBA is a new market and estimates vary significantly over the potential market size and our anticipated revenues over the near and long term.

     Our drug is being made available to patients to treat PBA, an indication for which there is no established pharmaceutical market. Industry sources and equity research analysts have a wide divergence of estimates for the near- and long-term market potential of our product. A variety of assumptions directly impact the estimates for our drug’s market potential, including estimates of underlying neurologic condition prevalence, severity of PBA prevalence among these conditions, and rates of physician adoption of our drug for treatment of PBA among these populations, drug pricing assumptions, and patient adherence and compliance rates within each underlying neurologic condition. Small differences in these assumptions can lead to widely divergent estimates of the market potential of our product. Additionally, although our approved product label is indicated to treat PBA, without regard for the underlying neurological condition, it is possible that physicians, the FDA’s Division of Drug Marketing, Advertising and Communication (“DDMAC”) or others may interpret the label more narrowly than the FDA’s approving division’s approval for a broad PBA label and believe that PBA secondary to certain conditions, such as Alzheimer’s disease, is not an indicated use. If such interpretations are widespread, the actual market size may be smaller than we have estimated. Accordingly, investors are cautioned not to place undue reliance on any particular estimates of equity research analysts or industry sources.

     Significant safety or drug interaction problems could arise with respect to NUEDEXTA, which could result in restrictions in NUEDEXTA’s label, recalls, withdrawal of NUEDEXTA from the market, an adverse impact on potential sales of NUEDEXTA, or cause us to alter or terminate current or future NUEDEXTA clinical development programs, any of which would adversely impact our future business prospects.

     Discovery of previously unknown safety or drug interaction problems with an approved product may result in a variety of adverse regulatory actions. This risk may be increased as physicians, at their own discretion, may prescribe NUEDEXTA for off-label uses which may result in unknown safety or drug interactions. Under the Food and Drug Administration Amendments Act of 2007, the FDA has broad authority to force drug manufacturers to take any number of actions if previously unknown safety or drug interaction problems arise, including, but not limited to: (i) requiring manufacturers to conduct post-approval clinical studies to assess known risks or signals of serious risks, or to identify unexpected serious risks; (ii) mandating labeling changes to a product based on new safety information; or (iii) requiring manufacturers to implement a Risk Evaluation Mitigation Strategy, or REMS, where necessary to assure safe use of the drug. In addition, previously unknown safety or drug interaction problems could result in product recalls, restrictions on the product’s permissible uses, or withdrawal of the product from the market.

     The combination of dextromethorphan and quinidine has never been marketed for the treatment of any condition until the approval of NUEDEXTA. NUEDEXTA has only been studied in a limited number of patients in clinical studies and the data submitted to the FDA as part of our New Drug Application was obtained in controlled clinical trials of limited duration. In connection with the approval of NUEDEXTA, the FDA has required that we conduct certain post-approval studies, which include both non-clinical studies and a pediatric development plan. New safety or drug interaction issues may arise from these studies or as NUEDEXTA is used over longer periods of time by a wider group of patients. In addition, as we conduct other clinical trials for AVP-923 in other indications, new safety problems may be identified which could negatively impact both our ability to successfully complete these studies and the use and/or regulatory status of NUEDEXTA for the treatment of PBA. New safety or drug interaction issues may result in product liability lawsuits and may require us to, among other things, provide additional warnings and/or restrictions on the NUEDEXTA prescribing information, including a boxed warning, directly alert healthcare providers of new safety information, narrow our approved indications, or alter or terminate current or planned trials

for additional uses of AVP-923, any of which could have a significant adverse impact on potential sales of NUEDEXTA.

     In addition, if we are required to conduct additional post-approval clinical studies, implement a REMS, or take other similar actions, such requirements or restrictions could have a material adverse impact on our ability to generate revenues from sales of NUEDEXTA, and/or require us to expend significant additional funds.

     We have limited capital resources and may need to raise additional funds to support our operations.

     We have experienced significant operating losses in funding the research, development, clinical testing and commercialization of NUEDEXTA and our drug candidates. We expect to continue to incur substantial operating losses for the foreseeable future as we continue the commercial launch of NUEDEXTA. Although we had approximately $93.5 million in cash and cash equivalents and restricted investments in marketable securities as of June 30, 2011, we currently do not have sufficient revenue from NUEDEXTA or other sources of recurring revenue or cash flow from operations to sustain our operations on a profitable basis and it is possible that we may not be able to achieve profitability with our current capital resources.

     In light of our substantial long-term capital needs, we may need to partner (either in the U.S. or outside the U.S.) or raise additional capital in the future to finance our long-term operations, until we expect to be able to generate meaningful amounts of revenue from product sales. Based on our current loss rate and existing capital resources as of the date of this report, we estimate that we have sufficient funds to sustain our operations at their current and anticipated levels into the fourth quarter of calendar 2012, which includes the costs associated with the ongoing marketing of NUEDEXTA for PBA. Although we expect to be able to raise additional capital if needed, there can be no assurance that we will be able to do so or that the available terms of any financing would be acceptable to us. If we are unable to raise additional capital to fund future operations, then we may be unable to fully execute our development and commercialization plans for NUEDEXTA. This may result in significant delays or cutbacks in the commercialization of NUEDEXTA and may force us to further curtail our operations or seek to raise additional capital.

     If we raise additional capital, we may do so through various financing alternatives, including licensing or sales of our technologies, drugs and/or drug candidates, selling shares of common or preferred stock, through the acquisition of other companies, or through the issuance of debt. Each of these financing alternatives carries certain risks. Raising capital through the issuance of common stock may depress the market price of our stock. Any such financing will dilute our existing stockholders and, if our stock price is relatively depressed at the time of any such offering, the levels of dilution would be greater. In addition, debt financing, to the extent available, may involve agreements that include covenants limiting or restricting our ability to take specific actions, such as making capital expenditures or entering into licensing transactions. If we seek to raise capital through licensing transactions or sales of one or more of our technologies, drugs or drug candidates, as we have previously done with certain investigational compounds and docosanol 10% cream, then we will likely need to share a significant portion of future revenues from these drug candidates with our licensees. Additionally, the development of any drug candidates licensed or sold to third parties will no longer be in our control and thus we may not realize the full value of any such relationships.

     We have licensed or sold most of our non-core drug development programs and related assets and these and other possible future dispositions carry certain risks.

     We have entered into agreements for the licensing or sale of our non-core assets, including FazaClo, our anthrax antibody program, and other antibodies in our infectious disease program, as well as docosanol in the U.S. and other markets worldwide. As a result, we do not currently have a diversified pipeline of product candidates and our long-term success is currently dependent on NUEDEXTA. From time to time, we have been and will continue to be engaged in discussions with potential licensing or development partners for NUEDEXTA for PBA and/or AVP-923 for other indications and we may choose to pursue a partnership or license involving NUEDEXTA, if the terms are attractive. However, these transactions involve numerous risks, including:

•

diversion of management’s attention from normal daily operations of the business;

	•		disputes over earn-outs, working capital adjustments or contingent payment obligations;
	•		insufficient proceeds to offset expenses associated with the transactions; and
	•		the potential loss of key employees following such a transaction.

     Transactions such as these carry significant risks where a large portion of the total consideration is contingent upon post-closing events, such as commercialization or sales milestones. We may not exercise control over whether these milestones are met and, if they are not met, then a potentially large portion of the value of the transaction may not be realized. Disputes may also develop over these and other terms, such as representations and warranties, indemnities, earn-outs, and other provisions in the transaction agreements. If disputes are resolved unfavorably, our financial condition and results of operations may be adversely affected and we may not realize the anticipated benefits from the transactions.

     Disputes relating to these transactions can lead to expensive and time-consuming litigation and may subject us to unanticipated liabilities or risks, disrupt our operations, divert management’s attention from day-to-day operations, and increase our operating expenses.

     The FDA’s safety concerns regarding our prior formulation of NUEDEXTA, known as AVP-923, for the treatment of PBA extend to other clinical indications that we have been pursuing, including DPN pain. Due to these concerns, any future development of AVP-923 for other indications, including central neuropathic pain in patients with MS, is expected to use an alternative lower-dose quinidine formulation, which may negatively affect efficacy.

     We have successfully completed a single Phase III trial for AVP-923 in the treatment of DPN pain. In communications regarding the continued development of AVP-923 for this indication, the FDA has expressed that the safety concerns and questions raised in the PBA approvable letter necessitate the testing of a low-dose quinidine formulation in the DPN pain indication as well. Additionally, based on feedback we have received from the FDA on the proposed continued development of AVP-923 for this indication, we believe it is likely that two large well-controlled Phase III trials would be needed to support a supplemental NDA filing for this indication. Due to our limited capital resources, we do not expect that we will be able to conduct the trials needed for this indication without additional capital or a development partner for NUEDEXTA. Moreover, although we achieved positive results in our initial Phase III trial, an alternative low-dose quinidine formulation may not yield the same levels of efficacy as seen in the earlier trials or as predicted based on our subsequent pharmacokinetic study. Any decrease in efficacy may be so great that the drug does not demonstrate a statistically significant improvement over placebo or an active comparator. Additionally, any alternative low-dose quinidine formulation that we develop may not sufficiently satisfy the FDA’s safety concerns. If this were to happen, we may not be able to pursue the development of AVP-923 for other indications, including central neuropathic pain in patients with MS, or may need to undertake significant additional clinical trials, which would be costly and cause potentially substantial delays.

     We rely on market research to evaluate the potential commercial acceptance of NUEDEXTA.

     Based on the results of our market research, we believe that physicians are likely to support the use and adoption of NUEDEXTA for the treatment of PBA. We conducted market research in accordance with Good Marketing Research Practices; however, research findings may not be indicative of the response we might receive from a broader sample of physicians. Moreover, these results are based on physicians’ impressions formed from a description of the product, and not actual results from having prescribed the product, which could result in different responses from those same or other physicians.

     It is unclear whether we would be eligible for patent-term restoration in the U.S. under applicable law and we therefore do not know whether our patent-term can be extended.

     Some of our U.S. patents may be eligible for limited patent term extension under the Drug Price Competition and Patent Term Restoration Act of 1984, referred to as the Hatch-Waxman Amendments. Due to receipt of approval for NUEDEXTA, the Hatch-Waxman Amendments permit a patent restoration term of up to five years for one of our patents covering NUEDEXTA as compensation for the patent term lost during product development and the regulatory review process. The patent term restoration period is generally one-half the time between the effective

date of an IND and the submission date of an NDA, plus the time between the submission date of an NDA and the approval of that application with a maximum of five years. In addition, the patent term restoration cannot extend the remaining term of a patent beyond a total of 14 years after the product’s approval date. We intend to apply for patent term restoration. However, because NUEDEXTA is not a new chemical entity, but is a combination of two previously approved products, it is uncertain whether NUEDEXTA will be granted any patent term restoration under the U.S. Patent and Trademark Office guidelines.

     Market exclusivity provisions under the Federal Food, Drug and Cosmetic Act, or the FDCA, may also delay the submission or the approval of certain applications for competing product candidates. The FDCA provides three years of non-patent marketing exclusivity for an NDA if new clinical investigations, other than bioavailability studies, that were conducted or sponsored by the applicant are deemed by the FDA to be essential to the approval of the application. This three-year exclusivity covers only the conditions associated with the new clinical investigations and does not prohibit the FDA from approving abbreviated NDAs (ANDA) for drugs containing the original active agent.

     Once the three-year FDCA exclusivity period has passed and after the patents (including the patent restoration term, if any) that cover NUEDEXTA expire or have been invalidated, generic drug companies would be able to introduce competing versions of the drug. If we are unsuccessful in defending our patents against generic competition, our long-term revenues from NUEDEXTA sales may be less than expected, we may have greater difficulty finding a development partner or licensee for NUEDEXTA and the costs to defend the patents would be significant.

     We may be unable to protect our unpatented proprietary technology and information.

     In addition to our patented intellectual property, we also rely on trade secrets and confidential information. We may be unable to effectively protect our rights to such proprietary technology or information. Other parties may independently develop or gain access to equivalent technologies or information and disclose it for others to use. Disputes may arise about inventorship and corresponding rights to know-how and inventions resulting from the joint creation or use of intellectual property by us and our corporate partners, licensees, scientific and academic collaborators and consultants. In addition, confidentiality agreements and material transfer agreements we have entered into with these parties and with employees and advisors may not provide effective protection of our proprietary technology or information or, in the event of unauthorized use or disclosure, may not provide adequate remedies.

     If we fail to obtain regulatory approval in foreign jurisdictions, we would not be able to market our products abroad and our revenue prospects would be limited.

     We may seek to have our products or product candidates marketed outside the United States. In order to market our products in the European Union and many other foreign jurisdictions, we must obtain separate regulatory approvals and comply with numerous and varying regulatory requirements. The approval procedure varies among countries and jurisdictions and can involve additional testing. The time required to obtain approval may differ from that required to obtain FDA approval. The foreign regulatory approval processes may include all of the risks associated with obtaining FDA approval. We may not obtain foreign regulatory approvals on a timely basis, if at all, and may not qualify or be accepted for accelerated review in foreign countries. For example, our development partner in Japan encountered significant difficulty in seeking approval of docosanol in that country and was forced to abandon efforts to seek approval in that country. Approval by the FDA does not ensure approval by regulatory authorities in other countries or jurisdictions, and approval by one foreign regulatory authority does not ensure approval by regulatory authorities in other foreign countries or jurisdictions or by the FDA. We may not be able to file for regulatory approvals and may not receive necessary approvals to commercialize our products in any market. The failure to obtain these approvals could materially adversely affect our business, financial condition and results of operations.

     We face challenges recruiting and retaining members of management and other key personnel.

     The industry in which we compete has a high level of employee mobility and aggressive recruiting of skilled employees. This type of environment creates intense competition for qualified personnel, particularly in commercial,

clinical and regulatory affairs, research and development and accounting and finance. Because we have a relatively small management team, the loss of any executive officers, including the Chief Executive Officer, key members of senior management or other key employees, could adversely affect our operations. For example, if we were to lose one or more of the senior members of our sales and marketing team, the success of the ongoing marketing of NUEDEXTA could be adversely affected.

     Our operations might be interrupted by the occurrence of a natural disaster or other catastrophic event.

     Our principal operations are located in Aliso Viejo, California. We depend on our facilities and on our partners, contractors and vendors for the continued operation of our business. Natural disasters or other catastrophic events, interruptions in the supply of natural resources, political and governmental changes, wildfires and other fires, floods, explosions, actions of animal rights activists, earthquakes and civil unrest could disrupt our operations or those of our partners, contractors and vendors. Even though we believe we carry commercially reasonable business interruption and liability insurance, and our contractors may carry liability insurance that protect us in certain events, we might suffer losses as a result of business interruptions that exceed the coverage available under our and our contractors’ insurance policies or for which we or our contractors do not have coverage. Any natural disaster or catastrophic event could have a significant negative impact on our operations and financial results. Moreover, any such event could impact the commercialization of NUEDEXTA and our research and development programs.

     Future business development activity could disrupt our business and harm our financial condition.

     In order to augment our product pipeline or otherwise strengthen our business, we may decide to acquire additional businesses, products and technologies. As we have limited experience in evaluating and completing acquisitions, our ability as an organization to make such acquisitions is unproven. Acquisitions could require significant capital infusions and could involve many risks, including, but not limited to, the following:

•		we may have to issue debt or equity securities to complete business development activities, which would dilute our stockholders and could adversely affect the market price of our common stock;
•		business development activity may negatively impact our results of operations because it may require us to amortize or write down amounts related to goodwill and other intangible assets, or incur or assume substantial debt or liabilities, or it may cause adverse tax consequences, substantial depreciation or deferred compensation charges;
•		we may encounter difficulties in assimilating and integrating the business, products, technologies, personnel or operations of companies that we acquire;
•		certain business development activities may impact our relationship with existing or potential partners who are competitive with the acquired business, products or technologies;
•		business development activities may require significant capital infusions and the acquired businesses, products or technologies may not generate sufficient value to justify acquisition costs;
•		business development activity may disrupt our ongoing business, divert resources, increase our expenses and distract our management;
•		business development activities may involve the entry into a geographic or business market in which we have little or no prior experience; and
•		key personnel of an acquired company may decide not to work for us.

     If any of these risks occurred, it could adversely affect our business, financial condition and operating results. We cannot assure you that we will be able to identify or consummate any future acquisitions on acceptable terms, or

at all. If we do pursue any acquisitions, it is possible that we may not realize the anticipated benefits from such acquisitions or that the market will not view such acquisitions positively.

Risks Relating to Our Industry

     The pharmaceutical industry is highly competitive and most of our competitors have larger operations and have greater resources. As a result, we face significant competitive hurdles.

     The pharmaceutical and biotechnology industries are highly competitive and subject to significant and rapid technological change. We compete with hundreds of companies that develop and market products and technologies in areas similar to those in which we are performing our research. For example, we expect that NUEDEXTA will face competition from antidepressants, atypical anti-psychotic agents and other agents in the treatment of PBA. Additionally, NUEDEXTA is currently facing challenges from “generic” drug companies, as described above.

     Our competitors may have specific expertise and development technologies that are better than ours and many of these companies, which include large pharmaceutical companies, either alone or together with their research partners, have substantially greater financial resources, larger research and development capabilities and substantially greater experience than we do. Accordingly, our competitors may successfully develop competing products. We are also competing with other companies and their products with respect to manufacturing efficiencies and marketing capabilities, areas where we have limited or no direct experience.

     If we fail to comply with regulatory requirements, regulatory agencies may take action against us, which could significantly harm our business.

     Marketed products, along with the manufacturing processes, post-approval clinical data, labeling, advertising and promotional activities for these products, are subject to continual requirements and review by the FDA and other regulatory bodies. In addition, regulatory authorities subject a marketed product, its manufacturer and the manufacturing facilities to ongoing review and periodic inspections. We will be subject to ongoing FDA requirements, including required submissions of safety and other post-market information and reports, registration requirements, current Good Manufacturing Practices (“cGMP”) regulations, requirements regarding the distribution of samples to physicians and recordkeeping requirements.

     The cGMP regulations also include requirements relating to quality control and quality assurance, as well as the corresponding maintenance of records and documentation. We rely on the compliance by our contract manufacturers with cGMP regulations and other regulatory requirements relating to the manufacture of products. We are also subject to state laws and registration requirements covering the distribution of our products. Regulatory agencies may change existing requirements or adopt new requirements or policies. We may be slow to adapt or may not be able to adapt to these changes or new requirements.

     We face uncertainty related to healthcare reform, pricing and reimbursement, which could reduce our revenue.

     In the United States, President Obama signed in March 2010 the Patient Protection and Affordable Care Act, as amended by the Health Care and Education Affordability Reconciliation Act (collectively, “PPACA”), which is expected to substantially change the way health care is financed by both governmental and private payors. PPACA provides for changes to extend medical benefits to those who currently lack insurance coverage, encourages improvements in the quality of health care items and services, and significantly impacts the U.S. pharmaceutical industry in a number of ways, further listed below. By extending coverage to a larger population, PPACA may substantially change the structure of the health insurance system and the methodology for reimbursing medical services, drugs and devices. These structural changes, as well as other changes that may be made as part of deficit and debt reduction efforts in Congress, could entail modifications to the existing system of private payors and government programs, such as Medicare, Medicaid and State Children’s Health Insurance Program, as well as the creation of a government-sponsored healthcare insurance source, or some combination of both. Such restructuring of the coverage of medical care in the United States could impact the extent of reimbursement for prescribed drugs, including our product candidates, biopharmaceuticals, and medical devices. Some of the specific PPACA provisions, among other things:

	•		Establish annual, non-deductible fees on any entity that manufactures or imports certain branded prescription drugs and biologics, beginning in 2011;
	•		Increase minimum Medicaid rebates owed by manufacturers under the Medicaid Drug Rebate Program;
	•		Extend manufacturers’ Medicaid rebate liability to covered drugs dispensed to individuals who are enrolled in Medicaid managed care organizations;
	•		Establish a new Patient-Centered Outcomes Research Institute to oversee, identify priorities in and conduct comparative clinical effectiveness research;
	•		Require manufacturers to participate in a coverage gap discount program, under which they must agree to offer 50 percent point-of-sale discounts off negotiated prices of applicable brand drugs to eligible beneficiaries during their coverage gap period, as a condition for the manufacturer’s outpatient drugs to be covered under Medicare Part D, beginning in 2011; and
	•		Increase the number of entities eligible for discounts under the Public Health Service pharmaceutical pricing program, effective January 2010.

     If future reimbursement for NUEDEXTA or any other approved product candidates, if any, is substantially less than we project, or rebate obligations associated with them are substantially increased, our business could be materially and adversely impacted.

     Sales of NUEDEXTA for treatment of patients with PBA will depend in part on the availability of coverage and reimbursement from third-party payors such as government insurance programs, including Medicare and Medicaid, private health insurers, health maintenance organizations and other health care related organizations. Accordingly, coverage and reimbursement may be uncertain. Adoption of NUEDEXTA by the medical community may be limited if third-party payors will not offer coverage. Cost control initiatives may decrease coverage and payment levels for NUEDEXTA and, in turn, the price that we will be able to charge. We are unable to predict all changes to the coverage or reimbursement methodologies that will be applied by private or government payors to NUEDEXTA. Any denial of private or government payor coverage or inadequate reimbursement for procedures performed using NUEDEXTA could harm our business and reduce our revenue.

     In addition, both the federal and state governments in the United States and foreign governments continue to propose and pass new legislation affecting coverage and reimbursement policies, which are designed to contain or reduce the cost of health care, as well as hold public hearings on these matters, which has resulted in certain private companies dropping the prices of their drugs. In May 2011, we received a letter from four members of the 112th Congress of the United States requesting certain information relating to the Company, FDA interactions, and the pricing of NUEDEXTA. The materials we provided in response to this letter were discussed in a report issued by the Senate Special Committee on Aging and we believe this matter to be closed. However, we cannot be certain the matter is closed or whether there will be future inquiries on the subject of NUEDEXTA pricing or what the impact might be of any such future inquiries. Further federal and state proposals and healthcare reforms are likely, which could limit the prices that can be charged for the product candidates that we develop and may further limit our commercial opportunity. There may be future changes that result in reductions in current coverage and reimbursement levels for our products, if commercialized, and we cannot predict the scope of any future changes or the impact that those changes would have on our operations.

     We rely on insurance companies to mitigate our exposure for business activities, including developing and marketing pharmaceutical products for human use.

     The conduct of our business, including the testing, marketing and sale of pharmaceutical products, involves the risk of liability claims by consumers, stockholders, and other third parties. Although we maintain various types of insurance, including product liability and director and officer liability, claims can be high and our insurance may not sufficiently cover our actual liabilities. If liability claims were made against us, it is possible that our insurance carriers may deny, or attempt to deny, coverage in certain instances. If a lawsuit against us is successful, then the lack or insufficiency of insurance coverage could materially and adversely affect our business and financial

condition. Furthermore, various distributors of pharmaceutical products require minimum product liability insurance coverage before their purchase or acceptance of products for distribution. Failure to satisfy these insurance requirements could impede our ability to achieve broad distribution of our proposed products and the imposition of higher insurance requirements could impose additional costs on us. Additionally, we are potentially at risk if our insurance carriers become insolvent. Although we have historically obtained coverage through highly rated and capitalized firms, the ongoing financial crisis may affect our ability to obtain coverage under existing policies or purchase insurance under new policies at reasonable rates.

     If we market products in a manner that violates health care fraud and abuse laws, we may be subject to civil or criminal penalties.

     We are also subject to healthcare fraud and abuse regulation and enforcement by both the federal government and the states in which we conduct our business. The laws that may affect our ability to operate include:

	•		the federal healthcare programs’ Anti-Kickback Law, which prohibits, among other things, persons from knowingly and willfully soliciting, receiving, offering or paying remuneration, directly or indirectly, in exchange for or to induce either the referral of an individual for, or the purchase, order or recommendation of, any good or service for which payment may be made under federal healthcare programs such as the Medicare and Medicaid programs;
	•		federal false claims laws which prohibit, among other things, individuals or entities from knowingly presenting, or causing to be presented, claims for payment from Medicare, Medicaid, or other third-party payors that are false or fraudulent;
	•		the federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, which created federal criminal laws that prohibit executing a scheme to defraud any healthcare benefit program or making false statements relating to healthcare matters; and
	•		state law equivalents of each of the above federal laws, such as anti-kickback and false claims laws that may apply to items or services reimbursed by any third-party payor, including commercial insurers.

     If our operations are found to be in violation of any of the laws described above or any other governmental regulations that apply to us, we may be subject to penalties, including civil and criminal penalties, damages, fines, exclusion from governmental health care programs, and the curtailment or restructuring of our operations, any of which could adversely affect our ability to operate our business and our financial results. The risk of our being found in violation of these laws is increased by the fact that many of them have not been fully interpreted by the regulatory authorities or the courts, and their provisions are open to a variety of interpretations. Further, the recently enacted PPACA, among other things, amends the intent requirement of the federal anti-kickback and criminal health care fraud statutes. A person or entity no longer needs to have actual knowledge of this statute or specific intent to violate it. In addition, the PPACA provides that the government may assert that a claim including items or services resulting from a violation of the federal anti-kickback statute constitutes a false or fraudulent claim for purposes of the false claims statutes. Moreover, some states, such as California, Massachusetts and Vermont, mandate implementation of commercial compliance programs to ensure compliance with these laws. Any action against us for violation of these laws, even if we successfully defend against it, could cause us to incur significant legal expenses and divert our management’s attention from the operation of our business.

     In addition, there has been a recent trend of increased federal and state regulation of payments made to physicians for marketing, including the tracking and reporting of gifts, compensation, and other remuneration to physicians. The shifting commercial compliance environment and the need to build and maintain robust and expandable systems to comply with multiple jurisdictions with different compliance and/or reporting requirements increases the possibility that a healthcare company may run afoul of one or more of the requirements.

     The PPACA also imposes new reporting and disclosure requirements on drug manufacturers for any “transfer of value” made or distributed to prescribers and other healthcare providers, effective March 30, 2013. Such information will be made publicly available in a searchable format beginning September 30, 2013. In addition, drug manufacturers will also be required to report and disclose any investment interests held by physicians and their

immediate family members during the preceding calendar year. Failure to submit required information may result in civil monetary penalties of up to an aggregate of $150,000 per year (and up to an aggregate of $1 million per year for “knowing failures”), for all payments, transfers of value or ownership or investment interests not reported in an annual submission. Finally, under PPACA, effective April 1, 2012, pharmaceutical manufacturers and distributors must provide the U.S. Department of Health and Human Services with an annual report on the drug samples they provide to physicians.

     We may incur significant liability if it is determined that we are promoting the “off-label” use of drugs.

     Companies may not promote drugs for “off-label” uses — that is, uses that are not described in the product’s labeling and that differ from those approved by the FDA, Therapeutic Products Directorate, or TPD, or other applicable regulatory agencies. Physicians may prescribe drug products for off-label uses, and such off-label uses are common across medical specialties. Although the FDA, TPD and other regulatory agencies do not regulate a physician’s choice of treatments, the FDA, TPD and other regulatory agencies do restrict communications by pharmaceutical companies or their sales representatives on the subject of off-label use. The FDA, TPD and other regulatory agencies actively enforce regulations prohibiting promotion of off-label uses and the promotion of products for which marketing clearance has not been obtained. A company that is found to have improperly promoted off-label uses may be subject to significant liability, including civil and administrative remedies as well as criminal sanctions. Notwithstanding the regulatory restrictions on off-label promotion, the FDA, TPD and other regulatory authorities allow companies to engage in truthful, non-misleading, and non-promotional speech concerning their products. The Company has taken numerous steps to ensure compliance is a high priority thoughout the organization and we believe that all of our communications regarding all of our products are in compliance with the relevant regulatory requirements, however, the FDA, TPD or another regulatory authority may disagree, and we may be subject to significant liability, including civil and administrative remedies, as well as criminal sanctions. In addition, management’s attention could be diverted from our business operations and our reputation could be damaged. Our distribution partners may also be the subject of regulatory investigations involving, or remedies or sanctions for, off-label uses of products we have licensed to them, which may have an adverse impact on sales of such licensed products, which may, in turn, have a material adverse effect on our business, financial condition and results of operations and could cause the market value of our common shares to decline.

     There are a number of difficulties and risks associated with clinical trials and our trials may not yield the expected results.

     There are a number of difficulties and risks associated with conducting clinical trials. For instance, we may discover that a product candidate does not exhibit the expected therapeutic results, may cause harmful side effects or have other unexpected characteristics that may delay or preclude regulatory approval or limit commercial use if approved. It typically takes several years to complete a late-stage clinical trial and a clinical trial can fail at any stage of testing. If clinical trial difficulties or failures arise, our product candidates may never be approved for sale or become commercially viable.

     In addition, the possibility exists that:

	•		the results from earlier clinical trials may not be predictive of results that will be obtained from subsequent clinical trials, particularly larger trials;
	•		institutional review boards or regulators, including the FDA, may hold, suspend or terminate our clinical research or the clinical trials of our product candidates for various reasons, including noncompliance with regulatory requirements or if, in their opinion, the participating subjects are being exposed to unacceptable health risks;
	•		subjects may drop out of our clinical trials;
	•		our preclinical studies or clinical trials may produce negative, inconsistent or inconclusive results, and we may decide, or regulators may require us, to conduct additional preclinical studies or clinical trials;

	•		trial results derived from top-line data, which is based on a preliminary analysis of efficacy and safety data related to primary and secondary endpoints, may change following a more comprehensive review of the complete data set derived from a particular clinical trial or may change due to FDA requests to analyze the data differently; and
	•		the cost of our clinical trials may be greater than we currently anticipate.

     It is possible that earlier clinical and pre-clinical trial results may not be predictive of the results of subsequent clinical trials. If earlier clinical and/or pre-clinical trial results cannot be replicated or are inconsistent with subsequent results, our development programs may be cancelled or deferred. In addition, the results of these prior clinical trials may not be acceptable to the FDA or similar foreign regulatory authorities because the data may be incomplete, outdated or not otherwise acceptable for inclusion in our submissions for regulatory approval.

     Additionally, the FDA has substantial discretion in the approval process and may reject our data or disagree with our interpretations of regulations or draw different conclusions from our clinical trial data or ask for additional information at any time during their review.

     Although we would work to be able to fully address any such FDA concerns, we may not be able to resolve all such matters favorably, if at all. Disputes that are not resolved favorably could result in one or more of the following:

	•		delays in our ability to submit an NDA;
	•		the refusal by the FDA to accept for filing any NDA we may submit;
	•		requests for additional studies or data;
	•		delays in obtaining an approval;
	•		the rejection of an application; or
	•		the approval of the drug, but with adverse labeling claims that could adversely affect the commercial market.

     If we do not receive regulatory approval to sell our product candidates or cannot successfully commercialize our product candidates, we would not be able to generate meaningful levels of sustainable revenues.

Risks Related to Reliance on Third Parties

     We depend on third parties to manufacture, package and distribute compounds for our drugs and drug candidates. The failure of these third parties to perform successfully could harm our business.

     We have utilized, and intend to continue utilizing, third parties to manufacture, package and distribute NUEDEXTA and the API for docosanol 10% cream and to provide clinical supplies of our drug candidates. We have no experience in manufacturing and do not have any manufacturing facilities. Currently, we have sole suppliers for the API for docosanol and NUEDEXTA, and a sole manufacturer for the finished form of NUEDEXTA. In addition, these materials are custom and available from only a limited number of sources. In particular, there may be a limited supply source for APIs in NUEDEXTA. Although we maintain a significant supply of APIs on hand, any sustained disruption in this supply could adversely affect our operations and revenues. Any material disruption in manufacturing could cause a delay in shipments and possible loss of sales. We do not have any long-term agreements in place with our current docosanol supplier or NUEDEXTA API suppliers. If we are required to change manufacturers, we may experience delays associated with finding an alternate manufacturer that is properly qualified to produce supplies of our products and product candidates in accordance with FDA requirements and our specifications. Any delays or difficulties in obtaining APIs or in manufacturing, packaging or distributing NUEDEXTA could negatively affect our sales revenues, as well as delay our clinical trials of this product candidate for DPN pain, MS-related pain or other potential indications. The third parties we rely on for manufacturing and packaging are also subject to regulatory review, and any regulatory compliance problems with these third parties

could significantly delay or disrupt our commercialization activities. Additionally, the ongoing economic crisis creates risk for us if any of these third parties suffer liquidity or operational problems. If a key third party vendor becomes insolvent or is forced to lay off workers assisting with our projects, our results and development timing could suffer.

     Because we depend on clinical research centers and other contractors for clinical testing and for certain research and development activities, the results of our clinical trials and such research activities are, to a certain extent, beyond our control.

     The nature of clinical trials and our business strategy of outsourcing a substantial portion of our research require that we rely on clinical research centers and other contractors to assist us with research and development, clinical testing activities, patient enrollment and regulatory submissions to the FDA. As a result, our success depends partially on the success of these third parties in performing their responsibilities. Although we pre-qualify our contractors and we believe that they are fully capable of performing their contractual obligations, we cannot directly control the adequacy and timeliness of the resources and expertise that they apply to these activities. Additionally, the current global economic slowdown may affect our development partners and vendors, which could adversely affect their ability to timely perform their tasks. If our contractors do not perform their obligations in an adequate and timely manner, the pace of clinical development, regulatory approval and commercialization of our drug candidates could be significantly delayed and our prospects could be adversely affected.

     We generally do not control the development of compounds licensed to third parties and, as a result, we may not realize a significant portion of the potential value of any such license arrangements.

     Under our typical license arrangement we have no direct control over the development of drug candidates and have only limited, if any, input on the direction of development efforts. These development efforts are made by our licensing partner, and if the results of their development efforts are negative or inconclusive, it is possible that our licensing partner could elect to defer or abandon further development of these programs. We similarly rely on licensing partners to obtain regulatory approval for docosanol in foreign jurisdictions. Because much of the potential value of these license arrangements is contingent upon the successful development and commercialization of the licensed technology, the ultimate value of these licenses will depend on the efforts of licensing partners. If our licensing partners do not succeed in developing the licensed technology for whatever reason, or elect to discontinue the development of these programs, we may be unable to realize the potential value of these arrangements. If we were to license NUEDEXTA to a third party or a development partner, it is likely that much of the long-term success of that drug will similarly depend on the efforts of the licensee.

     We expect to rely entirely on third parties for international registration, sales and marketing efforts.

     In the event that we attempt to enter into international markets, we expect to rely on collaborative partners to obtain regulatory approvals and to market and sell our product(s) in those markets. We have not yet entered into any collaborative arrangement with respect to marketing or selling NUEDEXTA, with the exception of one such agreement relating to Israel. We may be unable to enter into any other arrangements on terms favorable to us, or at all, and even if we are able to enter into sales and marketing arrangements with collaborative partners, we cannot assure you that their sales and marketing efforts will be successful. If we are unable to enter into favorable collaborative arrangements with respect to marketing or selling NUEDEXTA in international markets, or if our collaborators’ efforts are unsuccessful, our ability to generate revenues from international product sales will suffer.

Risks Relating to Our Stock

     Our stock price has historically been volatile and we expect that this volatility will continue for the foreseeable future.

     The market price of our common stock has been, and is likely to continue to be, highly volatile. This volatility can be attributed to many factors independent of our operating results, including the following:

•

comments made by securities analysts, including changes in their recommendations;

	•		short selling activity by certain investors, including any failures to timely settle short sale transactions;
	•		announcements by us of financing transactions and/or future sales of equity or debt securities;
	•		sales of our common stock by our directors, officers or significant stockholders, including sales effected pursuant to predetermined trading plans adopted under the safe-harbor afforded by Rule 10b5-1;
	•		regulatory developments in the U.S. and foreign countries, including the passage of laws, rules or regulations relating to healthcare and reimbursement or the public announcement of inquiries relating to these subjects;
	•		lack of volume of stock trading leading to low liquidity; and
	•		market and economic conditions.

     If a substantial number of shares are sold into the market at any given time, particularly following any significant announcements or large swings in our stock price (whether sales are under our existing “shelf” registration statements, from an existing stockholder, or the result of warrant or stock options exercised), there may not be sufficient demand in the market to purchase the shares without a decline in the market price for our common stock. Moreover, continuous sales into the market of a number of shares in excess of the typical trading volume for our common stock, or even the availability of such a large number of shares, could depress the trading market for our common stock over an extended period of time.

     Additionally, our stock price has been volatile as a result of announcements of regulatory actions and decisions relating to NUEDEXTA, and periodic variations in our operating results. We expect that our operating results will continue to vary from quarter to quarter, particularly as we continue to market NUEDEXTA and report initial sales results. Our operating results and prospects may also vary depending on the status of our partnering arrangements.

     As a result of these factors, we expect that our stock price may continue to be volatile and investors may be unable to sell their shares at a price equal to, or above, the price paid. Additionally, any significant drops in our stock price could give rise to stockholder lawsuits, which are costly and time consuming to defend against and which may adversely affect our ability to raise capital while the suits are pending, even if the suits are ultimately resolved in favor of the Company. We have, from time to time, been a party to such suits and although none have been material to date, there can be no assurance that any such suit will not have an adverse effect on the Company.

     If our internal controls over financial reporting are not considered effective, our business and stock price could be adversely affected.

     Section 404 of the Sarbanes-Oxley Act of 2002 requires us to evaluate the effectiveness of our internal controls over financial reporting as of the end of each fiscal year, and to include a management report assessing the effectiveness of our internal controls over financial reporting in our annual report on Form 10-K for that fiscal year. Section 404 also requires our independent registered public accounting firm to attest to, and report on, management’s assessment of our internal controls over financial reporting, and we again became subject to these requirements starting with the year ended September 30, 2010.

     Our management, including our chief executive officer and principal financial officer, does not expect that our internal controls over financial reporting will prevent all errors and all fraud. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the control system’s objectives will be met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud involving a company have been, or will be, detected. The design of any system of controls is based in part on certain assumptions about the likelihood of future events, and we cannot assure you that any design will succeed in achieving its stated goals under all potential future conditions. Over time, controls may become ineffective because of changes in conditions or deterioration in the degree of compliance with policies or procedures. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be

detected. We cannot assure you that we or our independent registered public accounting firm will not identify a material weakness in our internal controls in the future. A material weakness in our internal controls over financial reporting would require management and our independent registered public accounting firm to consider our internal controls as ineffective. If our internal controls over financial reporting are not considered effective, we may experience a loss of public confidence, which could have an adverse effect on our business and on the market price of our common stock.

     Because we do not expect to pay dividends in the foreseeable future, you must rely on stock appreciation for any return on your investment.

     We have paid no cash dividends on our common stock to date, and we currently intend to retain our future earnings, if any, to fund the development and growth of our business. As a result, we do not expect to pay any cash dividends in the foreseeable future, and payment of cash dividends, if any, will also depend on our financial condition, results of operations, capital requirements and other factors and will be at the discretion of our board of directors. Furthermore, we may in the future become subject to contractual restrictions on, or prohibitions against, the payment of dividends. Accordingly, the success of your investment in our common stock will likely depend entirely upon any future appreciation. There is no guarantee that our common stock will appreciate in value or even maintain the price at which you purchased your shares, and you may not realize a return on your investment in our common stock.

     Our corporate governance documents, rights agreement and Delaware law may delay or prevent an acquisition of us that stockholders may consider favorable, which could decrease the value of our common stock.

     Our certificate of incorporation and bylaws and Delaware law contain provisions that could make it more difficult for a third party to acquire us without the consent of our board of directors. These provisions include restrictions on the ability of our stockholders to remove directors and supermajority voting requirements for stockholders to amend our organizational documents and a classified board of directors. In addition, our board of directors has the right to issue preferred stock without stockholder approval, which could be used to dilute the stock ownership of a potential hostile acquirer. Delaware law, for instance, also imposes some restrictions on mergers and other business combinations between any holder of 15% or more of our outstanding common stock and us. Although we believe these provisions protect our stockholders from coercive or otherwise unfair takeover tactics and thereby provide for an opportunity to receive a higher bid by requiring potential acquirers to negotiate with our board of directors, these provisions apply even if the offer may be considered beneficial by some stockholders. We have also adopted a stockholder rights agreement intended to deter hostile or coercive attempts to acquire us. Under the agreement, if a person becomes an “acquiring person,” each holder of a right (other than the acquiring person) will be entitled to purchase, at the then-current exercise price, such number of shares of our preferred stock which are equivalent to shares of common stock having twice the exercise price of the right. If we are acquired in a merger or other business combination transaction after any such event, each holder of a right will then be entitled to purchase, at the then-current exercise price, shares of the acquiring company’s common stock having a value of twice the exercise price of the right. Our stockholder rights agreement could make it more difficult for a third party to acquire, or could discourage a third party from acquiring, us or a large block of our common stock without the support of our board of directors. Therefore, the agreement makes an acquisition much more costly to a potential acquirer.
