NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(UNAUDITED)

1. ORGANIZATION AND BASIS OF PRESENTATION

Organization

     Questcor Pharmaceuticals, Inc. (the “Company” or “Questcor”) is a pharmaceutical company that markets H.P. Acthar^® Gel (repository corticotropin injection), an injectable drug that is approved for the treatment of certain disorders with an inflammatory component, including the treatment of exacerbations associated with multiple sclerosis (“MS”), and the treatment of nephrotic syndrome. H.P. Acthar Gel (“Acthar”) is not indicated for, but is also used in treating patients with infantile spasms (“IS”), a rare form of refractory childhood epilepsy, and opsoclonus myoclonus syndrome, a rare autoimmune-related childhood neurological disorder. The Company has resubmitted its supplemental New Drug Application (“sNDA”) to the FDA seeking approval to market Acthar for the treatment of infantile spasms. The Company also markets Doral^® (quazepam), which is indicated for the treatment of insomnia characterized by difficulty in falling asleep, frequent nocturnal awakenings, and/or early morning awakenings.

     In August 2007, the Company announced its Acthar-centric business strategy, which included a new pricing level for Acthar effective August 27, 2007. The strategy was adopted in order to best position Acthar to benefit patients, advance the Company’s product development programs and ensure that the Company become economically viable. Since the adoption of the strategy, the Company has expanded its sponsorship of Acthar patient assistance and co-pay assistance programs, which provide an important safety net for uninsured and under-insured patients using Acthar, and has established a group of representatives and medical science liaisons to work with healthcare providers who administer Acthar.

Basis of Presentation

     The Company has determined that it operates in one business segment, pharmaceutical products. The accompanying unaudited consolidated financial statements of the Company have been prepared in accordance with U.S. generally accepted accounting principles and applicable Securities and Exchange Commission regulations for interim financial information. These financial statements do not include all of the information and footnotes required by U.S. generally accepted accounting principles for complete financial statements. The unaudited consolidated financial statements should be read in conjunction with the audited financial statements and related footnotes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2008. The accompanying consolidated balance sheet at December 31, 2008 has been derived from the audited consolidated financial statements at that date. In the opinion of the Company’s management, all adjustments (consisting of normal recurring adjustments) considered necessary for the fair presentation of interim financial information have been included. Operating results for the interim period presented are not necessarily indicative of the results that may be expected for the year ending December 31, 2009 or for any future interim period. The consolidated financial statements include the accounts of the Company and its wholly owned subsidiary. All significant intercompany accounts and transactions have been eliminated. The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions about future events that affect the amounts reported in the financial statements and disclosures made in the accompanying notes to the consolidated financial statements. Actual results could differ from those estimates.

     The Company has evaluated subsequent events through November 9, 2009, the date the unaudited consolidated financial statements were issued, and determined that there were no material subsequent events that required disclosure in the consolidated financial statements.

2. REVENUE RECOGNITION

     Revenues from product sales are recognized based upon shipping terms, net of estimated reserves for Medicaid rebates, other government program rebates and chargebacks, co-pay assistance programs, product returns and payment discounts. Revenue is recognized upon customer receipt of the shipment, provided that title to the product and risk of loss transfer at the point of receipt by the customer. If the title to the product and risk of loss transfer at the point of shipment, revenue is recognized upon shipment of the product. The Company estimates reserves for Medicaid rebates to all states for products dispensed to patients covered by Medicaid and for government chargebacks for sales of its products by wholesalers and its specialty distributor to certain Federal government

organizations, including Tricare and the Veterans Administration. The Company estimates its reserves by utilizing historical information and data obtained from external sources.

     Significant judgment is inherent in the selection of assumptions and the interpretation of historical experience as well as the identification of external and internal factors affecting the estimates of the Company’s reserves for Medicaid rebates and other government program rebates and chargebacks. The Company believes that the assumptions used to estimate these sales reserves are reasonable considering known facts and circumstances. However, the Company’s actual Medicaid rebates and other government program rebates and chargebacks could differ significantly from its estimates because of unanticipated changes in prescription trends or patterns in the states’ submissions of Medicaid claims, adjustments to the amount of product in the distribution channel, and new interpretations of the Medicaid statutes and regulations. If actual Medicaid rebates and other government program rebates and chargebacks are significantly different from the Company’s estimates, such differences would be accounted for in the period in which they become known.

     Historically, actual amounts have generally been consistent with the Company’s estimates; however, during the three month period ended September 30, 2009, the Company received higher than anticipated amounts of Medicaid rebates related to prior period Acthar usage. In connection with its receipt of these rebates, the Company increased its rebate reserve which reduced net sales in the current quarter by approximately $4.6 million.

     During the three month period ended September 30, 2009, the Company recorded an additional rebate reserve which reduced net sales by $1.4 million as a result of a final rule issued by the Department of Defense for potential rebates due for drugs sold by retail pharmacies to Tricare beneficiaries. Of the $1.4 million recorded during the three month period ended September 30, 2009, $0.4 million related to sales that were recorded in the quarter ended June 30, 2009.

     The Company utilizes the services of CuraScript, Inc. which has a specialty distributor subsidiary, CuraScript Specialty Distribution, Inc. (“CuraScript SD”) and a group of specialty pharmacies (“CuraScript SP”). During July 2007, the Company began utilizing CuraScript SD to distribute Acthar. Effective August 1, 2007, the Company no longer sells Acthar to wholesalers and all of the Company’s proceeds from sales of Acthar in the United States are received from CuraScript SD. The Company sells Acthar to CuraScript SD at a discount from the Company’s list price. CuraScript SD sells Acthar primarily to hospitals and specialty pharmacies. Product sales are recognized net of this discount upon receipt of the product by CuraScript SD. In April 2008, the Company announced the amendment of its distribution agreement with CuraScript SD, which became effective on June 1, 2008. Under the new terms, the discount provided by the Company to CuraScript SD was reduced from $1,047 per vial to $230 per vial. The new discounted sales price to CuraScript SD is $23,039 per vial and the stated list price remains at $23,269. However, under the new terms the pricing to CuraScript SD customers is unchanged. The amount of the discount to CuraScript SD is subject to annual adjustments based on the Consumer Price Index. In addition, the payment terms were reduced from 60 days to 30 days from when product is received by CuraScript SD. Under the Company’s distribution agreement with CuraScript SD, if the price of Acthar is reduced, CuraScript SD will receive a shelf-stock adjustment credit based upon the amount of product in their inventory at the time of the price reduction. Any reduction in the selling price of Acthar is at the Company’s discretion. To date, there have been no such price reductions. The Company does not require collateral from its customers.

     The Company supplies replacement product to CuraScript SD on product returned between one month prior to expiration to three months post expiration. Returns from product lots are exchanged for replacement product, and estimated costs for such exchanges, which include actual product material costs and related shipping charges are included in cost of sales. Product returns have been insignificant since the Company began utilizing the services of CuraScript SD to distribute Acthar.

     The Company provides a rebate related to product dispensed to Medicaid eligible patients in instances where regulations provide for such a rebate. The Company’s a) estimated rebate percentage adjusted for b) recent and expected future utilization rates for these programs, is used to estimate the rebate units associated with product shipped during the period as follows:

	a)		The estimated liability included in sales-related reserves as of the end of a period is comprised of the estimated rebate units associated with end user demand data during the period, the estimated rebate units associated with estimated inventory in the distribution channel as of the end of the period, and the estimated rebate units associated with prior rebate periods.
	b)		In order to assess current and future rates of Medicaid utilization, the Company analyzes inventory levels received from a third party, CuraScript SD, patient prescription and shipment data received from a third party, CuraScript SP, and claims-level detail received from state Medicaid agencies.

     The rebate amount per unit is determined based on a formula established by statute that is subject to review and modification by the administrators of the Medicaid program. The rebate per unit formula is comprised of a basic rebate of 15.1% applied to the average per unit amount of payments the Company receives on its product sales and an additional per unit rebate that is based on the Company’s current sales price compared to its sales price on an inflation adjusted basis from a designated base period. The Company multiplies the rebate amount per unit by the estimated rebate units to arrive at the reserve for the period. This reserve is deducted from gross sales in the determination of net sales. Effective January 1, 2008, the amount the Company rebates for each Acthar vial dispensed to a Medicaid eligible patient is approximately $2,500 higher than the price to CuraScript SD. The Medicaid rebates associated with end user demand for a period are mostly paid to the states by the end of the quarter following the quarter in which the rebate reserve is established.

     Certain other government-supported entities such as the Veterans Administration and Department of Defense are permitted to purchase Acthar from CuraScript SD for a nominal amount. CuraScript SD charges the significant discount back to the Company and reduces subsequent payment to the Company by the amount of the approved chargeback. The chargeback approximates the Company’s sales price to its customers. As a result, the Company recognizes nominal, if any, net sales on shipments that qualify for the government chargeback. The reduction to gross sales for a period related to chargebacks is comprised of actual approved chargebacks originating during the period and an estimate of chargebacks in the ending inventory of the Company’s customers. In estimating the government chargeback reserve as of the end of a period, the Company estimates the amount of chargebacks in its customers’ ending inventory using actual average monthly chargeback amounts and ending inventory balances provided by the Company’s largest customers. Chargebacks are generally applied by customers against their payments to the Company approximately 30 to 45 days after the customers have provided appropriate documentation to confirm their sale to a qualified government-supported entity.

     At September 30, 2009 and December 31, 2008, sales-related reserves included in the accompanying Consolidated Balance Sheets were as follows (in thousands):

		September 30,				December 31,

     As of September 30, 2009, the average contractual maturity of the Company’s short-term investments was approximately 11 months.

     As of September 30, 2009, the Company had the following available-for-sale securities that were in an unrealized loss position but were not deemed to be other-than-temporarily impaired (in thousands):

		Less Than 12 Months								12 Months or Greater
		Gross				Estimated				Gross				Estimated
		Unrealized				Fair				Unrealized				Fair

Total		$	(28	)		$	9,624			$	—			$	—

     The gross unrealized losses reported above for September 30, 2009 were caused by general fluctuations in market interest rates from the respective purchase date of these securities through September 30, 2009. No significant facts or circumstances have occurred to indicate that these unrealized losses are related to any deterioration in the creditworthiness of the issuers of the marketable securities the Company owns. Based on the Company's review of these securities, including its assessment of the duration and severity of the related unrealized losses, the Company has not recorded any other-than-temporary impairments on these investments.

Fair Value

     Effective January 1, 2008, the Company adopted Accounting Standards Codification (ASC) 820, Fair Value Measurements and Disclosures (formerly SFAS No. 157). ASC 820 applies to all fair value measurements not otherwise specified in an existing standard, clarifies how to measure fair value, and expands fair value disclosures. ASC 820 does not significantly change the Company’s previous practice with regard to asset valuation. The ASC 820 framework clarifies that fair value is an exit price, representing the amount that would be received to sell an asset or the amount paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability.

     As a basis for considering such assumptions, ASC 820 establishes a three-tier value hierarchy, which prioritizes the inputs used in measuring fair value as follows: (Level 1) observable inputs such as quoted market prices in active markets; (Level 2) inputs other than quoted prices in active markets that are observable either directly or indirectly; and (Level 3) unobservable inputs in which there is little or no market data, which require the Company to develop its own assumptions. This hierarchy requires the Company to use observable market data, when available, and to minimize the use of unobservable inputs when determining fair value. On a recurring basis, the Company measures its marketable debt securities at fair value. The Company’s fair market value measurements utilize either quoted prices in active markets (“Level 1”) or prices using readily observable inputs (“Level 2”) for all of its short-term investments, and are as a result valued at either the Level 1 or Level 2 fair value hierarchy as defined in ASC 820.

     The following methods and assumptions were used to determine the fair value of each class of assets and liabilities recorded at fair value in the consolidated balance sheets:

     Cash equivalents: Cash equivalents primarily consist of highly rated money market funds with maturities of one year or less, and are purchased daily at par value with specified yield rates. Due to the high ratings and short-term nature of these funds, the Company considers all cash equivalents as Level 1 inputs.

     Short-term available-for-sale investments at fair value: Fair values are based on quoted market prices, where available. These fair values are obtained from third party pricing services, which generally use Level 1 or Level 2 inputs for the determination of fair value in accordance with ASC 820. Third party pricing services normally derive the security prices through recently reported trades for identical or similar securities making adjustments through the reporting date based upon available market observable information. For securities not actively traded, the third party pricing services may use quoted market prices of comparable instruments or discounted cash flow analyses, incorporating inputs that are currently observable in the markets for similar securities. Inputs that are often used in valuation methodologies include, but are not limited to, benchmark yields, reported trades, broker/dealer quotes, issuer spreads, benchmark securities, bids, offers, and reference data. While the Company utilizes multiple third party pricing services to obtain fair value, it generally obtains one price for each individual security. The Company performs monthly analyses on the prices received from third parties to determine whether the prices are reasonable estimates of fair value. The analyses include a review of month to month price fluctuations and, as needed, a comparison of pricing services’ valuations to other pricing services’ valuations for the identical security. The Company also reviews the fair value hierarchy classification. Changes in the observability of valuation inputs may result in a reclassification of levels for certain securities within the fair value hierarchy.

     The following table summarizes the basis used to measure certain assets at fair value on a recurring basis in the accompanying Consolidated Balance Sheet at September 30, 2009 (in thousands):

		Basis of Fair Value Measurements
						Quoted prices				Significant
						in active				other				Significant

     Certain assets and liabilities are measured at fair value on a nonrecurring basis; that is, the instruments are not measured at fair value on an ongoing basis but are subject to fair value adjustments only in certain circumstances (for example, when there is evidence of impairment). There were no assets or liabilities measured at fair value on a nonrecurring basis during the nine month period ended September 30, 2009.

5. INVENTORIES

     Inventory is comprised of raw materials, work-in-process and finished goods. The Company provides valuation reserves for estimated obsolescence or unmarketable inventory. In the quarter ended September 30, 2009, the Company reserved $500,000 for a manufactured lot of Acthar that did not meet specifications. In the third quarter of 2009 the Company manufactured a lot of Acthar active pharmaceutical ingredient which contributed to the increased inventory balance at September 30, 2009.

     Inventories are stated at the lower of cost (first-in, first-out method) or market and consist of the following (in thousands):

6. PURCHASED TECHNOLOGY

     Purchased technology at September 30, 2009 consists of the Company’s acquisition costs related to the May 2006 acquisition of the Doral product rights and a cash payment of $300,000 to IVAX Research, Inc. made in January 2007 to eliminate the Doral royalty obligation. The purchased technology is being amortized on a straight-line basis over Doral’s expected life of 15 years. Accumulated amortization for the Doral purchased technology was $940,000 as of September 30, 2009.

7. COMMITMENTS, INDEMNIFICATIONS AND CONTINGENCIES

     The Company leases a 30,000 square foot facility in Hayward, California. The Company does not occupy this space and has subleased the facility. The Company’s master lease on the Hayward facility expires in November 2012. As of September 30, 2009, the Company is obligated to pay rent on the Hayward facility of $2.8 million. Over the remaining term of the master lease the Company anticipates that it will receive approximately $1.3 million in sublease income to be used to pay a portion of its Hayward facility obligation. As of September 30, 2009 and December 31, 2008, the estimated liability related to the Hayward facility totaled $1.0 million and $1.2 million, respectively, and is included in Lease Termination and Deferred Rent Liabilities in the accompanying Consolidated Balance Sheets.

     The Company, as permitted under California law and in accordance with its Bylaws, indemnifies its officers and directors for certain events or occurrences while the officer or director is or was serving at the Company’s request in such capacity. The potential future indemnification limit is to the fullest extent permissible under California law; however, the Company has a director and officer insurance policy that limits its exposure and may enable it to recover a portion of any future amounts paid. The Company believes the fair value of these indemnification agreements is minimal. Accordingly, the Company has no liabilities recorded for these agreements as of September 30, 2009 and December 31, 2008.

     The Company has entered into employment agreements with its corporate officers that provide for, among other things, base compensation and/or other benefits in certain circumstances in the event of termination or a change in control. In addition, certain of the agreements provide for the accelerated vesting of outstanding unvested stock options upon a change in control.

     From time to time, the Company may become involved in claims and other legal matters arising in the ordinary course of business. On February 25, 2009, the Company received a Civil Investigative Demand (“CID”) from the Attorney General of the State of Missouri, in connection with its investigation into the Company’s pricing practices with respect to Acthar under Missouri’s Merchandising Practices Act. On May 7, 2009, the Company received a subpoena from the Attorney General of the State of New York, in connection with its investigation, under New York’s antitrust statute and Federal antitrust statutes, into the Company’s acquisition of Acthar from Aventis in 2001, the Company’s Acthar royalty arrangements and its subsequent pricing of Acthar. The Company has provided documents and information to the Attorney Generals of Missouri and New York. The Company intends to cooperate with those offices, as it has with respect to government inquiries of all types.

     Management is not currently aware of any claims or other legal matters that will have a material adverse affect on the financial position, results of operations or cash flows of the Company.

8. NET INCOME PER SHARE

     The Company computes basic net income per share applicable to common shareholders by dividing net income applicable to common shareholders by the weighted average common shares outstanding during the period. Diluted net income per share gives effect to all potentially dilutive common shares outstanding during the period such as options, warrants, convertible preferred stock, and contingently issuable shares.

     The following table presents the amounts and shares used in computing basic and diluted net income per share applicable to common shareholders for the three and nine month periods ended September 30, 2009 and 2008, and the effect of dilutive potential common shares on the number of shares used in computing diluted net income per share applicable to common shareholders. Dilutive potential common shares resulting from the assumed exercise of outstanding stock options and warrants are determined based on the treasury stock method (in thousands, except per share amounts).

		Three Months Ended								Nine Months Ended
		September 30,								September 30,
		2009				2008				2009				2008
Net income applicable to common shareholders		$	1,223			$	8,955			$	18,208			$	19,023

9. INCOME TAXES

     Income tax expense for the three month periods ended September 30, 2009 and 2008 was $0.7 million and $6.6 million, respectively. For the three month periods ended September 30, 2009 and 2008, the Company’s effective tax rate for financial reporting purposes was approximately 37.3% and 42.3%, respectively. For the nine month periods ended September 30, 2009 and 2008 income tax expense was $10.4 million and $16.7 million, respectively. For the nine month periods ended September 30, 2009 and 2008, the Company’s effective tax rate for financial reporting purposes was approximately 36.4% and 40.7%, respectively. The decrease in the Company’s effective income tax rate is due to the Company’s ability to fully utilize the IRC Section 199 domestic production activities deduction and a lower effective state tax rate due to the transition of one state from an income tax to a gross receipts tax.

10. COMPREHENSIVE INCOME

     Comprehensive income is comprised of net income and the change in unrealized holding gains and losses on available-for-sale securities (in thousands):

		Three Months Ended								Nine Months Ended
		September 30,								September 30,
		2009				2008				2009				2008

Comprehensive income		$	1,165			$	8,933			$	17,963			$	24,231

11. EQUITY TRANSACTIONS

     On February 29, 2008, the Company’s board of directors approved a stock repurchase plan that provides for the Company’s repurchase of up to 7 million of its common shares. Stock repurchases under this program may be made through either open market or privately negotiated transactions in accordance with all applicable laws, rules and regulations. On May 29, 2009, the Company’s board of directors increased the Company’s common share repurchase program authorization by an additional 6.5 million shares. There were no purchases in the quarter ended September 30, 2009. Under this stock repurchase plan, the Company has repurchased a total of 5.9 million shares of its common stock for $26.8 million through September 30, 2009, at an average price of $4.56 per share.

     On February 19, 2008, the Company repurchased all of the outstanding 2.2 million shares of Series A Preferred Stock from Shire Pharmaceuticals, Inc. for cash consideration of $10.3 million or $4.80 per share, the same price per preferred share as the closing price per share of the Company’s common stock on February 19, 2008. The Series A Preferred Stock had a carrying value of $5.1 million. The $5.2 million difference between the $10.3 million repurchase payment and the $5.1 million balance sheet carrying value was accounted for as a deemed dividend and reduced the Company’s net income in the determination of net income applicable to common shareholders in the accompanying Consolidated Statements of Income.

     During 2008 the Company completed two repurchases outside of its stock repurchase plan. On August 13, 2008, the Company completed a board-approved repurchase of 2,200,000 shares of its common stock from Chaumiere Consultadorio & Servicos SDC Unipessoal L.D.A., an entity owned by Paolo Cavazza and members of his family, for $10.9 million or $4.95 per share, and on September 3, 2008, the Company completed a board-approved repurchase of an additional 1,800,000 shares of its common stock from Inverlochy Consultadorio & Servicos L.D.A., an entity owned by Claudio Cavazza, for $9.1 million or $5.06 per share.

     On October 20, 2009, in connection with its regular review of trends and best practices in corporate governance, the Company’s board of directors unanimously approved two corporate governance matters to provide Questcor’s shareholders more say with respect to proposals to acquire the Company and better information about the economic interests of proponents of shareholder proposals and director nominations. The board voted to amend the Company’s shareholder rights plan to accelerate the final expiration date of the preferred stock purchase rights issued thereunder. The amendment had the effect of terminating the rights plan effective October 26, 2009. In addition, the board approved amendments to the Company’s bylaws to require any Questcor shareholder submitting a proposal or director nomination to provide information regarding hedging positions or other agreements that serve to mitigate the loss to or otherwise manage the risk of changes to Questcor’s stock price, and to update such information within 10 days after the record date for the Company’s annual meeting.

12. RECENTLY ISSUED ACCOUNTING STANDARDS

     In June 2009, the Financial Accounting Standards Board (“FASB”) issued Statement of Financial Accounting Standards (“SFAS”) Statement No. 168, The FASB Accounting Standards Codification™ (“ASC”). The FASB notes that the ASC will become the source

of authoritative U.S. generally accepted accounting principles (“GAAP”) recognized by the FASB to be applied by nongovernmental entities. All of the ASC content will carry the same level of authority, effectively superseding Statement No. 162. The GAAP hierarchy will be modified to include only two levels of GAAP: authoritative and non-authoritative. The ASC is effective for financial statements issued for interim and annual periods ending after September 15, 2009.

     In May 2009, the FASB issued an accounting standard codified in ASC 855, Subsequent Events (formerly SFAS No. 165) which provides guidance on management’s assessment of subsequent events. ASC 855 represents the inclusion of guidance on subsequent events in the accounting literature and is directed specifically to management, since management is responsible for preparing an entity’s financial statements. ASC 855 is not expected to significantly change practice because it includes guidance which is similar to that in AU Section 560, with some important modifications. The new standard clarifies that management must evaluate, as of each reporting period, events or transactions that occur after the balance sheet date through the date that the financial statements are issued or are available to be issued. Management must perform its assessment for both interim and annual financial reporting periods. The Company adopted ASC 855 effective June 30, 2009.

     In April 2009, the FASB issued an accounting standard codified in ASC 320, Investments-Debt and Equity Securities (formerly FASB Staff Position (FSP) 115-2 and FSP 124-2). ASC 320 provides greater clarity to investors about the credit and noncredit component of an other-than-temporary impairment event and to more effectively communicate when an other-than-temporary impairment event has occurred. ASC 320 applies to fixed maturity securities only and requires separate display of losses related to credit deterioration and losses related to other market factors. When an entity does not intend to sell the security and it is more likely than not that an entity will not have to sell the security before recovery of its cost basis, it must recognize the credit component of an other-than-temporary impairment in earnings and the remaining portion in other comprehensive income. In addition, upon adoption of ASC 320, an entity will be required to record a cumulative-effect adjustment as of the beginning of the period of adoption to reclassify the noncredit component of a previously recognized other-than-temporary impairment from retained earnings to accumulated other comprehensive income. ASC 320 is effective for the Company for the quarter ended June 30, 2009. The adoption of ASC 320 did not have an impact on the Company’s consolidated financial position and results of operations.

     In April 2009, the FASB issued an accounting standard codified in ASC 820, Fair Value Measurements and Disclosures (formerly FSP 157-4). ASC 820 provides additional authoritative guidance to assist both issuers and users of financial statements in determining whether a market is active or inactive, and whether a transaction is distressed. ASC 820 is effective for the Company for the quarter ended June 30, 2009. The adoption of ASC 820 did not have an impact on the Company’s consolidated financial position and results of operations.

     In April 2009, the FASB issued an accounting standard codified in ASC 825, Financial Instruments (formerly FSP 107-1 and APB 28-1). ASC 825 requires disclosures about fair value of financial instruments for interim reporting periods of publicly traded companies as well as in annual financial statements. ASC 825 is effective for the Company for the quarter ended June 30, 2009. The adoption of ASC 825 did not have an impact on the Company’s consolidated financial position and results of operations.

     In December 2007, the FASB issued an accounting standard codified in ASC 805, Business Combinations (formerly FAS No. 141(R)). ASC 805 establishes principles and requirements for how an acquirer in a business combination recognizes and measures in its financial statements the identifiable assets acquired, the liabilities assumed, and any controlling interest; recognizes and measures the goodwill acquired in the business combination or a gain from a bargain purchase; and determines what information to disclose to enable users of the financial statements to evaluate the nature and financial effects of the business combination. ASC 805 is to be applied prospectively to business combinations for which the acquisition date is on or after an entity’s fiscal year that begins after December 15, 2008. The Company will assess the impact of ASC 805 if and when a future acquisition occurs.

     In November 2007, the EITF issued an accounting standard codified in ASC 808, Collaborative Arrangements (formerly EITF 07-1). Companies may enter into arrangements with other companies to jointly develop, manufacture, distribute, and market a product. Often the activities associated with these arrangements are conducted by the collaborators without the creation of a separate legal entity (that is, the arrangement is operated as a “virtual joint venture”). The arrangements generally provide that the collaborators will share, based on contractually defined calculations, the profits or losses from the associated activities. Periodically, the collaborators share financial information related to product revenues generated (if any) and costs incurred that may trigger a sharing payment for the combined profits or losses. The consensus requires collaborators in such an arrangement to present the result of activities for which they act as the principal on a gross basis and report any payments received from (made to) other collaborators based on other applicable GAAP or, in the absence of other applicable GAAP, based on analogy to authoritative accounting literature or a reasonable, rational, and consistently applied accounting policy election. ASC 808 is effective for collaborative arrangements in place at the beginning of the annual period beginning after December 15, 2008. The adoption of ASC 808 did not have a material impact on the Company’s consolidated financial position and results of operations.

13. RELATED PARTY TRANSACTIONS

     An immediate family member of the Company’s CEO provided certain consulting services to the Company totaling $35,000 and $88,000 for the three and nine month periods ended September 30, 2009, respectively. This immediate family member of the CEO was hired as an employee effective September 8, 2009. In accordance with the Company’s Related Party Transaction Policy, this transaction was approved by the disinterested members of the Company’s board of directors. In addition, an immediate family member of one of the Company’s Vice Presidents is a Senior Vice President for a company that provided certain consulting services to the Company totaling $74,000 and $133,000 for the three and nine month periods ended September 30, 2009, respectively.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

     Except for the historical information contained herein, the following discussion contains forward-looking statements that involve risks and uncertainties. Our actual results could differ materially from those discussed herein. Factors that could cause or contribute to such differences include, but are not limited to, those discussed in this section, as well as those discussed in our Annual Report on Form 10-K for the year ended December 31, 2008, including Item 1 “Business of Questcor,” and Item 1A “Risk Factors,” as well as factors discussed in any documents incorporated by reference herein or therein. Whenever used in this Quarterly Report, the terms “Questcor,” “Company,” “we,” “our,” “ours,” and “us” refer to Questcor Pharmaceuticals, Inc. and its consolidated subsidiary.

Overview

     We market H.P. Acthar Gel (repository corticotropin injection), an injectable drug that is approved for the treatment of certain disorders with an inflammatory component, including the treatment of exacerbations associated with multiple sclerosis (“MS”), and the treatment of nephrotic syndrome. H.P. Acthar Gel (“Acthar”) is not indicated for, but is also used in treating patients with infantile spasms (“IS”), a rare form of refractory childhood epilepsy, and opsoclonus myoclonus syndrome, a rare autoimmune-related childhood neurological disorder. From time to time we receive prescriptions for Acthar for other conditions. We also market Doral (quazepam), which is indicated for the treatment of insomnia characterized by difficulty in falling asleep, frequent nocturnal awakenings, and/or early morning awakenings.

     In August 2007, we announced our Acthar-centric business strategy, which included a new pricing level for Acthar effective August 27, 2007. The strategy was adopted in order to best position Acthar to benefit patients, advance our product development programs and ensure that the company become economically viable. Since the adoption of the strategy, we have expanded our sponsorship of Acthar patient assistance and co-pay assistance programs, which provide an important safety net for uninsured and under-insured patients using Acthar, and have established a group of representatives and medical science liaisons to work with healthcare providers who administer Acthar. We continue to support the Acthar patient assistance programs, administered by the National Organization for Rare Disorders (“NORD”). These and other patient-oriented support programs have now provided free drug with commercial value of over $37 million to patients since September 2007. In addition to the free drug program, significant financial support continues to be provided to needy patients through NORD’s co-pay assistance programs that we sponsor. Because we are now economically viable, we have significantly improved our ability to maintain the long-term availability of Acthar and fund important medical research projects that have the goal of improving patient care, despite the deterioration of the current U.S. economic environment. We have been working closely with the neurology community to identify promising new projects for which we can provide needed financial support. We are providing support to leading researchers in their efforts to better understand the underlying disease processes that cause infantile spasms, a subject for which there has been little research funding in recent decades, as well as to better understand the drug’s mechanisms of action.

     Acthar is currently approved in the U.S. for the treatment of exacerbations associated with MS, nephrotic syndrome and many other conditions with an inflammatory component. Pursuant to guidelines published by the American Academy of Neurology and the Child Neurology Society, many child neurologists use Acthar to treat infants afflicted with IS even though it is not approved for this indication. In March 2009, we submitted our supplemental New Drug Application (“sNDA”) to the U.S. Food and Drug Administration (“FDA”) to add the treatment of infantile spasms to the list of approved indications on the Acthar label. In May 2009, we were informed by the FDA that in order for our sNDA to be considered a complete submission, we must perform additional statistical analyses relating to data from one secondary study within the filing and provide the data to the FDA. On October 15, 2009 we resubmitted our sNDA to the FDA. The resubmission included additional statistical analyses requested by the FDA. If the sNDA is approved, such approval could require various actions by Questcor, including modification of the existing Acthar label and/or the adoption of FDA-mandated risk evaluation and mitigation strategies. Previously, the FDA granted Orphan Designation to the active ingredient in Acthar for the treatment of IS. As a result of this Orphan Designation, if we are successful in obtaining FDA approval for the IS indication, we believe we will also qualify for a seven-year exclusivity period during which the FDA is prohibited from approving any other adrenocorticotropic hormone (ACTH) formulation for IS unless the other formulation is demonstrated to be

clinically superior to Acthar or is considered by the FDA to have an active ingredient that is different from the active ingredient of Acthar.

     In the first quarter of 2009, we completed the initial phase of our MS sales force expansion plan, hiring and training our sales force as well as completing all territorial realignments. A second phase of our sales force expansion was completed in the third quarter of 2009. Our expanded sales force of 38 representatives allows us to build upon continued positive growth trends in prescriptions of Acthar for the treatment of exacerbations associated with MS, an indication for which Acthar is already approved.

     We are also in discussions with experts in other disease states with high unmet medical needs for which there is a potential therapeutic role for Acthar. As a result of these initiatives, we are currently funding 25 pre-clinical and clinical studies. Many of these studies are examining the use of Acthar in the treatment of nephrotic syndrome, a disorder involving deterioration of kidney function that often leads to the need for renal dialysis or transplant. We are also now beginning to fund exploratory pre-clinical research evaluating whether Acthar could have potential value in the management of amyotrophic lateral sclerosis (also known as ALS or Lou Gehrig’s Disease) and traumatic brain injury.

     From January 1, 2009 through November 9, 2009, we have repurchased a total of 2.4 million shares of our common stock for $11.2 million under our stock repurchase plan, at an average price of $4.70 per share. In May 2009, our board of directors increased our common share repurchase program authorization by an additional 6.5 million shares. As of November 9, 2009, there are a total of 7.6 million shares authorized remaining under the revised stock repurchase plan. Since the initiation of this program in early 2008, we have returned approximately $57 million to shareholders through our common and preferred stock buyback efforts.

     Our results of operations may vary significantly from quarter to quarter depending on, among other factors, demand for our products by patients, inventory levels of our products held by third parties, the amount of Medicaid rebates on our products dispensed to Medicaid eligible patients, the amount of chargebacks on the sale of our products by our specialty distributor to government-supported entities, the availability of finished goods from our sole-source manufacturers, the timing of certain expenses, the introduction of a competitive product, and our ability to develop growth opportunities for Acthar.

Critical Accounting Policies

     Our management’s discussion and analysis of our financial condition and results of operations is based upon our consolidated financial statements, which have been prepared in accordance with U.S. generally accepted accounting principles. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosures. On an on-going basis, we evaluate our estimates, including those related to our Medicaid rebate obligation related to our products dispensed to Medicaid eligible patients, other government rebate programs and chargebacks on sales of our products by wholesalers and our specialty distributor to government-supported entities, inventories, intangible assets, share-based compensation, lease termination liability and income taxes. We base our estimates on historical experience and on various other assumptions that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions. We believe the following critical accounting policies affect our more significant judgments and estimates used in the preparation of our consolidated financial statements.

Sales Reserves

     For the three and nine month periods ended September 30, 2009 and 2008, we have estimated reserves for Medicaid rebates to all states for products dispensed to patients covered by Medicaid; government chargebacks for sales of our products by wholesalers and our specialty distributor to certain Federal government organizations including such organizations as the Veterans Administration; and reserves for rebates related to a health coverage program called Tricare. For the three and nine month periods ended September 30, 2008, we estimated reserves for product returns from our specialty distributor, wholesalers, hospitals and pharmacies. Gross sales are also reduced for payments made under our Acthar patient co-payment assistance programs. We estimate our reserves by utilizing historical information for our existing products and data obtained from external sources.

     Significant judgment is inherent in the selection of assumptions and the interpretation of historical experience as well as the identification of external and internal factors affecting the estimates of our reserves for Medicaid rebates and other government program rebates and chargebacks. We believe that the assumptions used to estimate these sales reserves are reasonable considering known facts and circumstances. However, our actual Medicaid rebates and other government program rebates and chargebacks could differ significantly from our estimates because of unanticipated changes in prescription trends or patterns in the states’ submissions of

Medicaid claims, adjustments to the amount of product in the distribution channel, and new interpretations of the Medicaid statutes and regulations. If actual Medicaid rebates, or other government program rebates and chargebacks are significantly different from our estimates, such differences would be accounted for in the period in which they become known. Historically, actual amounts have been generally consistent with our estimates. However, during the three month period ended September 30, 2009, we received higher than anticipated amounts of Medicaid rebates related to prior period Acthar usage. In connection with the receipt of these rebates, we increased our rebate reserve which reduced net sales in the third quarter of 2009 by approximately $4.6 million. During the three month period ended September 30, 2009, we recorded an additional rebate reserve which reduced net sales by $1.4 million as a result of a final rule issued by the Department of Defense for potential rebates due for drugs sold by retail pharmacies to Tricare beneficiaries. Of the $1.4 million recorded during the three month period ended September 30, 2009, $0.4 million related to sales that were recorded in the quarter ended June 30, 2009.

     Medicaid Rebates

     We provide a rebate related to product dispensed to Medicaid eligible patients in instances where regulations provide for such a rebate. Our a) estimated rebate percentage, adjusted for b) recent and expected future utilization rates for these programs, is used to estimate the rebate units associated with product shipped during a period as follows:

	a)		The estimated liability included in sales-related reserves as of the end of a period is comprised of the estimated rebate units associated with end user demand data during the period, the estimated rebate units associated with estimated inventory in the distribution channel as of the end of the period, and the estimated rebate units associated with prior rebate periods.
	b)		In order to assess current and future rates of Medicaid utilization, we analyze inventory levels received from a third party, CuraScript SD, patient prescription and shipment data received from a third party, CuraScript SP, and claims-level detail received from state Medicaid agencies.

     The rebate amount per unit is determined based on a formula established by statute and is subject to review and modification by the administrators of the Medicaid program. The rebate per unit formula is comprised of a basic rebate of 15.1% applied to the average per unit amount of payments we receive on our product sales and an additional per unit rebate that is based on our current sales price compared to our sales price on an inflation adjusted basis from a designated base period. We multiply the rebate amount per unit by the estimated rebate units to arrive at the reserve for the period. This reserve is deducted from gross sales in the determination of net sales. Effective January 1, 2008, the amount we rebate for each Acthar vial dispensed to a Medicaid eligible patient is approximately $2,500 higher than our price to CuraScript SD. Management believes that the information received from CuraScript SD related to inventory levels and CuraScript SP related to prescription and shipment data is reliable, but we are unable to independently verify the accuracy of such data. The Medicaid rebates associated with end user demand for a period are mostly paid to the states by the end of the quarter following the quarter in which the rebate reserve is established.

     Government Chargebacks

     Certain other government-supported entities such as the Veterans Administration and Department of Defense are permitted to purchase Acthar from CuraScript SD for a nominal amount. CuraScript SD charges the significant discount back to us and reduces subsequent payment to us by the amount of the approved chargeback. The chargeback approximates our sales price to our customers. As a result, we recognize nominal, if any, net sales on shipments to these entities that qualify for the government chargeback. The reduction to gross sales for a period related to chargebacks is comprised of actual approved chargebacks originating during the period and an estimate of chargebacks in the ending inventory of our customers. In estimating the government chargeback reserve as of the end of a period, we estimate the amount of chargebacks in our customers’ ending inventory using actual average monthly chargeback amounts and ending inventory balances provided by our largest customers. Chargebacks are generally applied by customers against their payments to us approximately 30 to 45 days after they have provided appropriate documentation to confirm their sale to a qualified government-supported entity.

     We routinely assess our experience with Medicaid rebates and government chargebacks and adjust the reserves accordingly. Revisions in the Medicaid rebate and chargeback estimates are charged to income in the period in which the information that gives rise to the revision becomes known.

     Tricare Rebates

     We have established a reserve for rebates related to a health coverage program called Tricare. On March 17, 2009, the Department of Defense issued final regulations under the Fiscal Year 2008 National Defense Authorization Act which interpreted such Act to expand Tricare to include prescription drugs dispensed by Tricare retail network pharmacies. Our Tricare rebate reserve reflects this program expansion and is based on estimated Department of Defense eligible sales multiplied by the Tricare rebate formula. In estimating our rebate eligible sales, we did not include sales prior to the effective date of the Department of Defense regulations, based on our interpretation of the regulations and a pending dispute between an industry coalition and the Department of Defense. We did not record reserves for retroactive rebates in the amount of $100,000 for 2008 and $1.2 million for the January-May 2009 timeframe. Depending on the outcome of this dispute, it is possible that we will need to increase our rebate reserve relating to Tricare for these amounts.

     Co-Pay Assistance Programs

     We sponsor co-pay assistance programs for Acthar patients which are administered by the National Organization for Rare Disorders (“NORD”). The payments made under our co-pay assistance programs are accounted for as a reduction of gross sales.

     Product Returns

     We supply replacement product to CuraScript SD on product returned between one month prior to expiration to three months post expiration. Returns from product lots are exchanged for replacement product, and estimated costs for such exchanges, which include actual product material costs and related shipping charges are included in cost of sales. Product returns have been insignificant since we began utilizing the services of CuraScript SD to distribute Acthar.

     Shelf-Stock Adjustment Credit

     Under our distribution agreement with CuraScript SD, if the price of Acthar is reduced, CuraScript SD will receive a shelf-stock adjustment credit based upon the amount of product in their inventory at the time of the price reduction. Any reduction in the selling price of Acthar is at our discretion. To date, there have been no such price reductions.

     At September 30, 2009 and December 31, 2008, sales-related reserves included in the accompanying Consolidated Balance Sheets were as follows (in thousands):

		September 30,				December 31,
		2009				2008
Medicaid rebates		$	12,492			$	11,406
Tricare rebates			1,400				—
Government chargebacks			73				164
Product returns			—				255
		$	13,965			$	11,825

Inventories

     As of September 30, 2009, our net raw material, work-in-process and finished goods inventories totaled $3.4 million. We maintain inventory reserves primarily for excess and obsolete inventory (due to the expiration of shelf life of a product). In estimating inventory excess and obsolescence reserves, we analyze (i) the expiration date, (ii) our sales forecasts and (iii) historical demand. Judgment is required in determining whether the forecasted sales information is sufficiently reliable to enable us to reasonably estimate excess and obsolete inventory. If actual future usage and demand for our products is less favorable than projected, additional inventory write-offs may be required in the future which would increase our cost of sales in the period of any write-offs. In the quarter ended September 30, 2009, we reserved $500,000 for a manufactured lot of Acthar that did not meet specifications. We intend to control inventory levels of our products purchased by our customers. Customer inventories may be compared to both internal and external databases to determine adequate inventory levels. We may monitor our product shipments to customers and compare these shipments against prescription demand for our individual products.

Intangible and Long-Lived Assets

     As of September 30, 2009, our intangible and long-lived assets consisted of goodwill of $299,000 generated from a merger in 1999, net purchased technology of $3.4 million related to our acquisition of Doral and $414,000 of net property and equipment. The costs related to our acquisition of Doral are being amortized over an estimated life of 15 years. The determination of whether or not

our intangible and long-lived assets are impaired and the expected useful lives of purchased technology involves significant judgment. Changes in strategy or market conditions could significantly impact these judgments and require a write-down of our recorded asset balances and a reduction in the expected useful life of our purchased technology. Such a write-down of our recorded asset balances or reduction in the expected useful life of our purchased technology would increase our operating expenses. In accordance with ASC 350, Intangibles-Goodwill and Other (formerly SFAS No. 142), we review goodwill for impairment on an annual basis or whenever events occur or circumstances change that could indicate a possible impairment may have occurred. Our fair value is compared to the carrying value of our net assets, including goodwill. If the fair value is greater than the carrying amount, then no impairment is indicated. In accordance with ASC 360, Property Plant and Equipment (formerly SFAS No. 144), we review long-lived assets, consisting of property and equipment and purchased technology, for impairment whenever events or circumstances indicate that the carrying amount may not be fully recoverable. Recoverability of assets is measured by comparison of the carrying amount of the asset to the net undiscounted future cash flows expected to be generated from the use or disposition of the asset. If the future undiscounted cash flows are not sufficient to recover the carrying value of the assets, the assets’ carrying value is adjusted to fair value. As of September 30, 2009, no impairment had been indicated.

Share-Based Compensation Expense

     Effective January 1, 2006, we adopted the fair value recognition provisions of ASC 718, Compensation-Stock Compensation (formerly SFAS No. 123(R)), using the modified-prospective transition method. Under the fair value recognition provisions of ASC 718, share-based compensation cost is estimated at the grant date based on the fair value of the award and is recognized as expense, net of estimated pre-vesting forfeitures, ratably over the vesting period of the award. We selected the Black-Scholes option pricing model as the most appropriate fair value method for our awards. Calculating share-based compensation expense requires the input of highly subjective assumptions, including the expected term of the share-based awards, stock price volatility, and pre-vesting forfeitures. We estimated the expected term of stock options granted for the three and nine month periods ended September 30, 2009 and 2008 based on the historical term of our stock option awards. We estimated the volatility of our common stock at the date of grant based on the historical volatility of our common stock. The assumptions used in calculating the fair value of share-based awards represent our best estimates, but these estimates involve inherent uncertainties and the application of management judgment. As a result, if factors change and we use different assumptions, our share-based compensation expense could be materially different in the future. In addition, we are required to estimate the expected pre-vesting forfeiture rate and only recognize expense for those shares expected to vest. We estimate the pre-vesting forfeiture rate based on historical experience. If our actual forfeiture rate is materially different from our estimate, our share-based compensation expense could be significantly different from what we have recorded in the current period.

     Our net income for the three and nine month periods ended September 30, 2009 included $669,000 and $2.4 million, respectively, of share-based compensation expense related to employees and non-employee members of our board of directors. Our net income for the three and nine month periods ended September 30, 2008 included $635,000 and $3.7 million, respectively, of share-based compensation expense related to employees and non-employee members of our board of directors.

Lease Termination Liability

     We entered into an agreement to sublease laboratory and office space, including laboratory equipment, at our Hayward, California facility in July 2000, due to the termination of our then existing drug discovery programs. The sublease on our Hayward facility expired in July 2006. Our obligations under the Hayward master lease extend through November 2012. During the fourth quarter of 2005, the sublessee notified us that they did not intend to extend the sublease beyond the end of July 2006.

     We determined that there was no loss associated with the Hayward facility when we initially subleased the space, as we expected cash inflows from the sublease to exceed our rent cost over the term of the master lease. However, we reevaluated this in 2005 when the sublessee notified us that it would not be renewing the sublease beyond July 2006. As a result, we computed a loss and liability on the sublease in the fourth quarter of 2005 in accordance with ASC 840, Leases (which now includes former FIN 27 and FTB 79-15). As of September 30, 2009 and December 31, 2008, the estimated liability related to the Hayward facility totaled $1.0 million and $1.2 million, respectively, and is included in Lease Termination and Deferred Rent Liabilities in the accompanying Consolidated Balance Sheets. The fair value of the liability was determined using a credit-adjusted risk-free rate to discount the estimated future net cash flows, consisting of the minimum lease payments under the master lease, net of estimated sublease rental income that could reasonably be obtained from the property. The most significant assumption in estimating the lease termination liability relates to our estimate of future sublease income. We base our estimate of sublease income, in part, on the opinion of independent real estate experts, current market conditions, and rental rates, among other factors. Adjustments to the lease termination liability will be required if actual sublease income differs from amounts currently expected. We review all assumptions used in determining the estimated

liability quarterly and revise our estimate of the liability to reflect changes in circumstances. Effective November 1, 2007, we subleased 5,000 square feet of the facility through April 2009 and effective February 1, 2008 we subleased the remaining 25,000 square feet through the remainder of the term of the master lease. The 5,000 square foot sublease is currently leased on a month-to-month basis. These subleases cover a portion of our lease commitment, and all of our insurance, taxes and common area maintenance. As of September 30, 2009, we are obligated to pay rent on the Hayward facility of $2.8 million. Over the remaining term of the master lease, we anticipate that we will receive approximately $1.3 million in sublease income to be used to pay a portion of our Hayward facility obligation.

     We are also required to recognize an on-going accretion expense representing the difference between the undiscounted net cash flows and the discounted net cash flows over the remaining term of the Hayward master lease using the interest method. The accretion amount represents an on-going adjustment to the estimated liability. The on-going accretion expense and any revisions to the liability are recorded in Selling, General and Administrative expense in the accompanying Consolidated Statements of Income.

Income Taxes

     We make certain estimates and judgments in determining income tax expense for financial statement purposes. These estimates and judgments occur in the calculation of certain tax assets and liabilities, which arise from differences in the timing of recognition of revenue and expense for tax and financial statement purposes.

     As part of the process of preparing our consolidated financial statements, we are required to estimate our income taxes in each of the jurisdictions in which we operate. This process involves us estimating our current tax exposure under the most recent tax laws and assessing temporary differences resulting from differing treatment of items for tax and accounting purposes. These differences result in deferred tax assets and liabilities, which are included in our consolidated balance sheets.

     We regularly assess the likelihood that we will be able to recover our deferred tax assets, which is ultimately dependent upon us generating future taxable income. We consider all available evidence, both positive and negative, including historical levels of income, expectations and risks associated with estimates of future taxable income and ongoing prudent and feasible tax planning strategies in assessing the need for a valuation allowance. If it is not considered “more likely than not” that we will recover our deferred tax assets, we will increase our provision for taxes by recording a valuation allowance against the deferred tax assets that we estimate will not ultimately be recoverable.

     In 2008, we reversed our remaining $5.2 million valuation allowance for deferred tax assets that we believe will be recovered based on anticipated taxable income in 2009 and future years. This reversal resulted in an income tax benefit of $750,000 and $4.4 million in the second and fourth quarters of 2008, respectively, which reduced our income tax expense. Any changes in the valuation allowance based upon our future assessment will result in an income tax expense if the valuation allowance is increased.

     At December 31, 2008, we had federal and state net operating loss carryforwards of $9.9 million and $16.8 million, respectively, and federal and California research and development tax credits of $591,000 and $940,000, respectively. Federal net operating loss carryforwards totaling $9.9 million are subject to annual limitations and will be available from 2009 through 2018, as a result of federal ownership change limitations. Of this amount, $2.1 million of federal net operating loss carryforwards are available to reduce our 2009 taxable income. State net operating loss carryforwards totaling $16.8 million are subject to annual limitations and are available from 2009 through 2018. In September 2008, California suspended for two years the ability to use state operating loss carryforwards and certain credit carryforwards to reduce taxable income. We expect to use these state operating loss carryforwards and certain credit carryforwards after the two year suspension. The federal and state net operating loss carryforwards and the federal credit carryforwards expire at various dates beginning in the years 2013 through 2026, if not utilized.

Net sales		$	13,851			$	24,200			$	(10,349	)			(43	)%

     Net sales for the three month periods ended September 30, 2009 and 2008 were comprised of our neurology products Acthar and Doral. Net sales of Acthar for the three month period ended September 30, 2009 totaled $13.6 million as compared to $24.0 million during the same period in 2008. The decrease in Acthar net sales resulted primarily from higher than anticipated amounts of Medicaid rebates related to Acthar usage in previous quarters and a lower number of shipped and paid prescriptions for the treatment of infantile spasms (IS). These factors were partially offset by the continued sequential improvement in sales of Acthar in the multiple sclerosis (MS) market.

     Sales reserves recorded in the third quarter of 2009 for Medicaid rebates, other government program rebates and chargebacks, and co-pay assistance programs were significantly higher than sales reserves recorded in the third quarter of 2008. We provide a rebate related to product dispensed to Medicaid eligible patients in instances where regulations provide for such a rebate. In addition, other government-supported entities are permitted to purchase our products for a nominal amount from our customers who charge back the significant discount to us. These Medicaid rebates and other government program rebates and chargebacks are estimated by us each quarter and reduce our gross sales in the determination of our net sales. Sales reserves related to government programs for Acthar shipments in the third quarter of 2009 were higher than prior quarters. Furthermore, the third quarter sales rebate reserves included a one-time adjustment of $4.6 million for higher prior period Medicaid rebate provisions which reduced net sales. In addition, as a result of a new assessment of our liability under a Department of Defense regulation, we reserved an additional rebate reserve which reduced net sales by $1.4 million for rebates related to a health coverage program called Tricare. Approximately $0.4 million of the Tricare rebate reserve related to sales that were recorded in the second quarter of 2009.

     In the third quarter of 2009, sales reimbursed by Medicaid represented a larger percentage of overall IS sales than in previous periods. During the third quarter of 2009, 119 new paid Acthar prescriptions for IS were processed by our reimbursement support center and shipped, a decrease of 26% from the second quarter of 2009. However, Medicaid and other government entity shipments remained relatively flat in the third quarter of 2009 as compared to the second quarter of 2009. We believe this pattern may be due to an increasing number of families losing employer-paid healthcare insurance and an easing of Medicaid eligibility requirements in certain states.

     During the third quarter of 2009 we shipped 1,354 Acthar vials to our specialty distributor as compared to 1,500 vials shipped during the third quarter of 2008. There has been significant variability in prescription activity on a monthly basis in the use of Acthar in the treatment of IS due to the very small IS patient population. For each of the three months in the third quarter of 2009, the monthly usage of Acthar for IS was at the low end of its two year historic monthly range. We believe it is possible that a portion of the usage decline was related to a lower national birth rate in 2009 and the greater use of alternative therapies for the treatment of IS.

     During the third quarter of 2009 we expanded our MS sales force to 38 representatives. The sales force expansion supports our increased sales efforts related to the use of Acthar for the treatment of exacerbations associated with MS, an indication for which Acthar is already approved. Our increased sales efforts have resulted in a significant increase in sales of Acthar to treat select MS exacerbation patients in the third quarter of 2009 as compared to the same period in 2008. During the third quarter of 2009, 161 new paid Acthar prescriptions were processed by our reimbursement support center and shipped to MS patients, a 14% increase over 141 new paid Acthar prescriptions shipped in the second quarter of 2009 and a 188% increase over the third quarter of 2008. We expect net sales of Acthar in the treatment of patients with MS exacerbations to continue to grow modestly in the fourth quarter of 2009.

     For the three month period ended September 30, 2009, to determine our net sales, Acthar gross sales were reduced by approximately 51% to account for the estimated amount of Medicaid rebates and government chargebacks, as compared to approximately 31% for the three month period ended September 30, 2008. The Medicaid rebate portion of sales reserves for the third quarter of 2009 was $14.1 million consisting of $9.5 million for Acthar shipments in the third quarter of 2009 and $4.6 million for

Acthar shipments in prior periods. A greater percentage of infants than adults are eligible for Medicaid, which results in fewer MS patients than IS patients participating in the Medicaid program. Effective January 1, 2008, the amount we rebate for each Acthar vial dispensed to a Medicaid eligible patient is approximately $2,500 higher than our price to our specialty distributor.

     Acthar orders may be affected by several factors, including inventory practices at specialty and hospital pharmacies, greater use of patient assistance programs, the overall pattern of usage by the healthcare community, including Medicaid and government-supported entities, the use of alternative therapies for the treatment of IS, and the reimbursement policies of insurance companies. Our specialty distributor ships Acthar to specialty pharmacies and hospitals to meet end user demand. We track our own Acthar shipments daily, but those shipments vary compared to end user demand because of seasonal usage and changes in inventory levels at specialty pharmacies and hospitals. We also review the amount of inventory of Acthar at CuraScript SD and Doral at wholesalers in order to help assess the demand for our products.

     Acthar shipments may be affected by seasonality as well as quarter to quarter fluctuations driven by the relatively small IS patient population. We believe these fluctuations are principally due to the low incidence of IS, as a relatively small number of cases can create meaningful fluctuations. We will continue to monitor these factors as there may be volatility in our Acthar shipments and end user demand in future periods.

     We expect quarterly fluctuations in net sales due to changes in demand for our products, the timing of shipments, changes in inventory levels, expiration dates of product sold, the impact of our sales-related reserves, and the potential impact of approval by the FDA of a competitive product for the treatment of IS.

Cost of Sales and Gross Profit

		Three Months Ended
		September 30,								Increase/				%
		2009				2008				(Decrease)				Change
		(in $000’s)
Cost of sales		$	2,006			$	1,937			$	69				4	%
Gross profit		$	11,845			$	22,263			$	(10,418	)			(47	)%
Gross margin			86	%			92	%

     Cost of sales for the three month period ended September 30, 2009 decreased $69,000 as compared to the three month period ended September 30, 2008. Cost of sales includes material costs, packaging, warehousing and distribution, product liability insurance, royalties, quality control (which primarily includes product stability testing), quality assurance and reserves for excess or obsolete inventory. The increase in cost of sales was due primarily to an inventory reserve of approximately $500,000, partially offset by a decrease in royalties on Acthar. During the third quarter of 2009, a manufactured lot of Acthar did not meet specifications and as a result we recorded a $500,000 reserve against that manufactured lot. The gross margin was 86% for the three month period ended September 30, 2009, as compared to 92% for the three month period ended September 30, 2008.

Selling, General and Administrative

		Three Months Ended
		September 30,								Increase/				%
		2009				2008				(Decrease)				Change
		(in $000’s)
Selling, general and administrative expense		$	7,676			$	4,251			$	3,425				81	%

     The increase in selling, general and administrative expense for the three month period ended September 30, 2009 as compared to the same period in 2008 was due primarily to increases in headcount-related costs and costs associated with the support of our Acthar strategy.

     Headcount-related costs included in selling, general and administrative expense, excluding share-based compensation, increased by approximately $1.0 million as compared to the same period in 2008. During the first quarter of 2009 we completed the expansion of our sales force to 30 representatives and added additional managers in order to build upon continued positive growth trends in prescriptions of Acthar for the treatment of exacerbations associated with MS, an indication for which Acthar is already approved. We completed a second phase of our MS sales force expansion to 38 representatives during the third quarter of 2009.

     Costs associated with the support of our Acthar strategy increased by approximately $1.8 million in the three month period ended September 30, 2009 as compared to the same period in 2008. The increase is due primarily to our marketing program for MS. An increase of approximately $400,000 for professional services also contributed to the increase in selling, general and administrative expense in the three month period ended September 30, 2009.

     We incurred a total non-cash charge of $669,000 for ASC 718 share-based compensation related to employees and non-employee members of our board of directors for the quarter ended September 30, 2009, as compared to $635,000 for the quarter ended September 30, 2008. Of this amount, $512,000 was included in selling, general and administrative expenses, as compared to $493,000 for the same period in 2008.

Research and Development

		Three Months Ended
		September 30,								Increase/				%
		2009				2008				(Decrease)				Change
		(in $000’s)
Research and development		$	2,215			$	2,577			$	(362	)			(14	)%

     Costs included in research and development relate primarily to costs related to the resubmission of our Acthar sNDA for IS to the FDA, the funding of medical research projects to better understand the therapeutic benefit of Acthar in current and new therapeutic applications, product development efforts and compliance activities. The decrease in research and development expenses was due primarily to decreases in costs related to our resubmission of our sNDA for IS and product development expenses. Expenses related to the resubmission of our sNDA and product development decreased approximately $600,000 in the three month period ended September 30, 2009 as compared to the same period in 2008. These decreases were partially offset by increased funding of medical research projects to better understand the therapeutic benefit of Acthar in current and new therapeutic applications. In October 2009 we resubmitted our sNDA to the FDA seeking approval to market Acthar for the treatment of infantile spasms. We are seeking a partner to complete development of QSC-001 so that our research and development resources can be focused on pursuing potential growth opportunities for Acthar that have recently been identified.

     A non-cash charge of $157,000 for ASC 718 share-based compensation was included in research and development expenses in the three month period ended September 30, 2009, which was consistent with share-based compensation expense for the same period in 2008.

     We are providing support to leading researchers in their efforts to better understand the underlying disease processes that cause infantile spasms, and are also in discussions with experts in other disease states with high unmet medical needs for which there is a potential therapeutic role for Acthar. As a result of these initiatives, we are currently funding 25 pre-clinical and clinical studies to explore potential new uses for Acthar, as well as to better understand the drug’s mechanisms of action.

Depreciation and Amortization

		Three Months Ended
		September 30,								Increase/				%
		2009				2008				(Decrease)				Change
		(in $000’s)
Depreciation and amortization		$	123			$	134			$	(11	)			(8	)%

     Depreciation and amortization expense for the three month period ended September 30, 2009 was consistent with depreciation and amortization expense for the same period in 2008.

Total Other Income

		Three Months Ended
		September 30,								Increase/				%
		2009				2008				(Decrease)				Change
		(in $000’s)
Total other income		$	120			$	209			$	(89	)			(43	)%

     Total other income for the three month period ended September 30, 2009 decreased $89,000 as compared to total other income for the same period in 2008. The decrease was due to lower interest income resulting from a lower yield on our cash, cash equivalent and short-term investment balances during the three month period ended September 30, 2009 as compared to the same period in 2008.

Income Before Income Taxes and Income Tax Expense

		Three Months Ended
		September 30,								Increase/				%
		2009				2008				(Decrease)				Change
		(in $000’s)
Income before income taxes		$	1,951			$	15,510			$	(13,559	)			(87	)%
Income tax expense		$	728			$	6,555			$	(5,827	)			(89	)%

     Income before income taxes for the three month period ended September 30, 2009 was $2.0 million as compared to $15.5 million for the three month period ended September 30, 2008. The decrease was due to the decrease in net sales and the changes in expenses discussed above. Income tax expense for the three month period ended September 30, 2009 was $728,000 as compared to $6.6 million for the three month period ended September 30, 2008. During the quarter ended September 30, 2009, our effective tax rate for financial reporting purposes was approximately 37.3% as compared to approximately 42.3% for the quarter ended September 30, 2008. The lower effective tax rate in the third quarter of 2009 was attributable to our ability to fully utilize the IRC Section 199 domestic production activities deduction and a lower effective state tax rate due to the transition of one state from an income tax to a gross receipts tax.

Net Income and Net Income Applicable to Common Shareholders

		Three Months Ended
		September 30,								Increase/				%
		2009				2008				(Decrease)				Change
		(in $000’s)
Net income and net income applicable to common shareholders		$	1,223			$	8,955			$	(7,732	)			(86	)%

     For the three month period ended September 30, 2009, net income was $1.2 million as compared to net income of $9.0 million for the three month period ended September 30, 2008, a decrease of $7.7 million. The decrease was due to the decrease in net sales and the changes in expenses discussed above. For the three month period ended September 30, 2009, net income applicable to common shareholders was $1.2 million, or $0.02 per fully diluted share, as compared to net income applicable to common shareholders of $9.0 million, or $0.13 per fully diluted share, for the three month period ended September 30, 2008.

Nine months ended September 30, 2009 compared to the nine months ended September 30, 2008:

     Net sales for the nine month periods ended September 30, 2009 and 2008 were comprised of our neurology products Acthar and Doral. Net sales of Acthar for the nine month period ended September 30, 2009 totaled $61.9 million as compared to $67.6 million during the same period in 2008. During the first nine months of 2009 we shipped 4,347 Acthar vials to our specialty distributor as compared to 4,320 vials shipped during the first nine months of 2008. The decrease in Acthar net sales resulted primarily from sales reserves recorded in the third quarter of 2009 for higher than anticipated amounts of Medicaid rebates related to Acthar usage in previous quarters. The increase in reserves was partially offset by the increase in sales of Acthar in the multiple sclerosis (MS) market.

     Sales reserves recorded in the first nine months of 2009 for Medicaid rebates, other government program rebates and chargebacks, and co-pay assistance programs were higher than sales reserves recorded in the first nine months of 2008. We provide a rebate related to product dispensed to Medicaid eligible patients in instances where regulations provide for such a rebate. In addition, other government-supported entities are permitted to purchase our products for a nominal amount from our customers who charge back the

significant discount to us. These Medicaid rebates and other government program rebates and chargebacks are estimated by us each quarter and reduce our gross sales in the determination of our net sales. Third quarter sales reserves included a one-time adjustment of $4.6 million for higher prior period Medicaid rebate provisions. In addition, as a result of a new assessment of our liability under a Department of Defense regulation, in the third quarter of 2009 we reserved an additional $1.4 million for rebates related to a health coverage program called Tricare. The reserve for the Tricare rebates was for the period of June 2009 through September 2009.

     For the nine month period ended September 30, 2009, Acthar gross sales were reduced by approximately 36% to account for the estimated amount of Medicaid rebates and government chargebacks, as compared to approximately 30% for the nine month period ended September 30, 2008. In the third quarter of 2009 we recorded reserves for Medicaid rebates totaling $14.1 million, which consisted of $9.5 million for Acthar shipments in the third quarter of 2009 and $4.6 million for Acthar shipments in prior periods. A greater percentage of infants than adults are eligible for Medicaid, which results in fewer MS patients than IS patients participating in the Medicaid program. Effective January 1, 2008, the amount we rebate for each Acthar vial dispensed to a Medicaid eligible patient is approximately $2,500 higher than our price to our specialty distributor.

     During the third quarter of 2009 we expanded our MS sales force to a total of 38 representatives. The sales force expansion supports our increased sales efforts related to the use of Acthar for the treatment of exacerbations associated with MS, an indication for which Acthar is already approved. During the first nine months of 2009, our increased MS sales efforts resulted in a significant increase in sales of Acthar to treat select MS exacerbation patients as compared to the first nine months of 2008. During the first nine months of 2009, 388 new paid Acthar prescriptions were processed by our reimbursement support center and shipped to MS patients, a 221% increase over 121 new paid Acthar prescriptions shipped in the first nine months of 2008.

     Acthar orders may be impacted by several factors, including inventory practices at specialty and hospital pharmacies, greater use of patient assistance programs, the overall pattern of usage by the healthcare community, including Medicaid and government-supported entities, the use of alternative therapies for the treatment of IS, and the reimbursement policies of insurance companies. Our specialty distributor ships Acthar to specialty pharmacies and hospitals to meet end user demand. We track our own Acthar shipments daily, but those shipments vary compared to end user demand because of seasonal usage and changes in inventory levels at specialty pharmacies and hospitals.

Cost of Sales and Gross Profit

		Nine Months Ended
		September 30,								Increase/				%
		2009				2008				(Decrease)				Change
		(in $000’s)
Cost of sales		$	5,119			$	5,446			$	(327	)			(6	)%
Gross profit		$	57,296			$	62,784			$	(5,488	)			(9	)%
Gross margin			92	%			92	%			—				—

     Cost of sales for the nine month period ended September 30, 2009 decreased $327,000 as compared to the nine month period ended September 30, 2008. The decrease in cost of sales was due primarily to decreases in distribution costs, royalties on Acthar and direct materials totaling approximately $600,000. These decreases were offset in part by an inventory reserve of approximately $500,000. During the third quarter of 2009, a manufactured lot of Acthar did not meet specifications and as a result we recorded a $500,000 reserve against that manufactured lot. The gross margin was 92% for each of the nine month periods ended September 30, 2009 and 2008.

Selling, General and Administrative

		Nine Months Ended
		September 30,								Increase/				%
		2009				2008				(Decrease)				Change
		(in $000’s)
Selling, general and administrative expense		$	22,109			$	14,172			$	7,937				56	%

     The increase in selling, general and administrative expense for the nine month period ended September 30, 2009 as compared to the same period in 2008 was due primarily to increases in headcount-related costs and costs associated with the support of our Acthar strategy, offset in part by lower share-based compensation expense.

     Headcount-related costs included in selling, general and administrative expense, excluding share-based compensation, increased by approximately $3.4 million as compared to the same period in 2008. The increase is due to the expansion of our sales force in order to build upon continued positive growth trends in prescriptions of Acthar for the treatment of exacerbations associated with MS. We completed an initial sales force expansion during the first quarter of 2009, and a second sales force expansion to 38 representatives was completed during the third quarter of 2009.

     Costs associated with the support of our Acthar strategy increased by approximately $3.9 million in the nine month period ended September 30, 2009 as compared to the same period in 2008. The increase is due primarily to our marketing program for MS. An increase of approximately $900,000 for professional services also contributed to the increase in selling, general and administrative expense in the nine month period ended September 30, 2009.

     We incurred a total non-cash charge of $2.4 million for ASC 718 share-based compensation related to employees and non-employee members of our board of directors for the nine month period ended September 30, 2009, as compared to $3.7 million for the nine month period ended September 30, 2008. Of this amount, $1.9 million was included in selling, general and administrative expenses, a decrease of $1.1 million as compared to the same period in 2008. The decrease in total share-based compensation expense in the first nine months of 2009 was due primarily to an approximate $1.8 million decrease in expense associated with our employee stock purchase plan as compared to the same period of 2008.

Research and Development

		Nine Months Ended
		September 30,								Increase/				%
		2009				2008				(Decrease)				Change
		(in $000’s)
Research and development		$	6,991			$	8,103			$	(1,112	)			(14	)%

     The decrease in research and development expenses was due primarily to decreases in costs related to our resubmission of our sNDA for IS and product development expenses. Expenses related to the resubmission of our sNDA and product development decreased approximately $2.1 million in the nine month period ended September 30, 2009 as compared to the same period in 2008. These decreases were partially offset by increased funding of medical research projects to better understand the therapeutic benefit of Acthar in current and new therapeutic applications. Expenses related to medical research projects increased approximately $700,000 in the nine month period ended September 30, 2009 as compared to the same period in 2008. In addition, headcount-related expenses, excluding share-based compensation, increased approximately $300,000 in the nine month period ended September 30, 2009 as compared to the same period in 2008.

     A non-cash charge of $477,000 for ASC 718 share-based compensation was included in research and development expenses in the nine month period ended September 30, 2009, a decrease of $183,000 as compared to the same period in 2008.

Depreciation and Amortization

Depreciation and amortization		$	359			$	379			$	(20	)			(5	)%

     Depreciation and amortization expense for the nine month period ended September 30, 2009 was consistent with depreciation and amortization expense for the same period in 2008.

Total Other Income

		Nine Months Ended

		2009				2008				(Decrease)				Change
		(in $000’s)
Total other income		$	810			$	828			$	(18	)			(2	)%

     Total other income for the nine month period ended September 30, 2009 decreased slightly as compared to total other income for the same period in 2008. Lower interest income resulting from a lower yield on our cash, cash equivalent and short-term investment

balances during the nine month period ended September 30, 2009 as compared to the same period in 2008 was offset in part by a $225,000 gain on sale of product rights.

Income Before Income Taxes and Income Tax Expense

		Nine Months Ended
		September 30,								Increase/				%
		2009				2008				(Decrease)				Change
		(in $000’s)
Income before income taxes		$	28,647			$	40,958			$	(12,311	)			(30	)%
Income tax expense		$	10,439			$	16,668			$	(6,229	)			(37	)%

     Income before income taxes for the nine month period ended September 30, 2009 was $28.6 million as compared to $41.0 million for the nine month period ended September 30, 2008. The decrease was due to the decrease in net sales and the changes in expenses discussed above. Income tax expense for the nine month period ended September 30, 2009 was $10.4 million as compared to $16.7 million for the nine month period ended September 30, 2008. During the nine months ended September 30, 2009, our effective tax rate for financial reporting purposes was approximately 36.4% as compared to approximately 40.7% for the nine months ended September 30, 2008. The lower effective tax rate in the first nine months of 2009 was attributable to our ability to fully utilize the IRC Section 199 domestic production activities deduction and a lower effective state tax rate due to the transition of one state from an income tax to a gross receipts tax.

Net Income

		Nine Months Ended
		September 30,								Increase/				%
		2009				2008				(Decrease)				Change
		(in $000’s)
Net income		$	18,208			$	24,290			$	(6,082	)			(25	)%

     For the nine month period ended September 30, 2009, net income was $18.2 million as compared to net income of $24.3 million for the nine month period ended September 30, 2008, a decrease of $6.1 million. The decrease resulted primarily from the decrease in net sales and the changes in expenses discussed above.

Series A Preferred Stock Dividend

		(in $000’s)
Deemed dividend on Series A Preferred Stock		$	—			$	5,267			$	(5,267	)			(100	)%

     The deemed dividend resulted from the repurchase of our Series A Preferred Stock in February 2008. We repurchased all of the outstanding Series A Preferred Stock in February 2008 for cash consideration of $10.3 million or $4.80 per share. As of December 31, 2007, the Series A Preferred Stock had a carrying amount of $5.1 million. The deemed dividend represents the difference between the $10.3 million repurchase payment and the $5.1 million balance sheet carrying value of the Series A Preferred Stock. The repurchase transaction had no income tax impact.

Net Income Applicable to Common Shareholders

		Nine Months Ended

		(in $000’s)
Net income applicable to common shareholders		$	18,208			$	19,023			$	(815	)			(4	)%

     For the nine month period ended September 30, 2009, net income applicable to common shareholders was $18.2 million, or $0.27 per fully diluted share, as compared to net income applicable to common shareholders of $19.0 million, or $0.26 per fully diluted share, for the nine month period ended September 30, 2008, a decrease of $815,000. In the nine month period ended September 30, 2008, the deemed dividend on Series A Preferred Stock reduced net income by $5.3 million, and reduced fully diluted earnings per share applicable to common shareholders by $0.07.

Liquidity and Capital Resources

     During the nine month period ended September 30, 2009, we generated $27.8 million in cash from operations. The $27.8 million in cash flow generated from operations included an $8.4 million increase in accounts payable at September 30, 2009 due to timing of Medicaid payments and a $2.1 million increase in sales-related reserves. During the nine month period ended September 30, 2008, we generated $53.7 million in cash from operations. The $53.7 million in cash flow generated from operations during the nine month period ended September 30, 2008 included a $12.5 million decrease in accounts receivable, an $8.5 million decrease in deferred tax assets, and a $5.8 million increase in sales-related reserves.

     At September 30, 2009, we had cash, cash equivalents and short-term investments of $73.3 million compared to $55.5 million at December 31, 2008. The increase was due primarily to $27.8 million of cash generated from operations and $859,000 in proceeds from the issuance of common stock under our employee stock purchase plan and from the exercise of stock options, partially offset by $11.2 million paid to repurchase our common stock. At September 30, 2009, our working capital was $69.9 million compared to $59.3 million at December 31, 2008. The increase in our working capital was principally due to the $17.8 million increase in cash, cash equivalents and short-term investments, an increase in prepaid income taxes of $1.9 million and an increase of $1.0 million in inventories, partially offset by an increase in accounts payable of $8.4 million and an increase in sales-related reserves of $2.1 million.

     In February 2008 our board of directors approved a stock repurchase plan that provides for our repurchase of up to 7 million of our common shares in either open market or private transactions, which will occur from time to time and in such amounts as management deems appropriate. On May 29, 2009, our board of directors increased our common share repurchase program authorization by an additional 6.5 million shares. Through November 9, 2009, we have repurchased a total of 5.9 million shares of our common stock for $26.8 million under our stock repurchase plan, at an average price of $4.56 per share. As of November 9, 2009, there are 7.6 million shares authorized remaining under the stock repurchase plan.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

     Our exposure to market risk at September 30, 2009 has not changed materially from December 31, 2008, and reference is made to the more detailed disclosures of market risk included in our Annual Report on Form 10-K for the year ended December 31, 2008.

ITEM 4. CONTROLS AND PROCEDURES

     We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in our Exchange Act reports is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow for timely decisions regarding required disclosure.

     In designing and evaluating the disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and management is required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Our disclosure controls and procedures were designed to provide reasonable assurance that the controls and procedures would meet their objectives.

     As required by SEC Rule 13a-15(b), we carried out an evaluation, under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures as of the end of the quarter covered by this report. Based on the foregoing, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective at the reasonable assurance level.

     There has been no change in our internal controls over financial reporting during our most recent fiscal quarter that has materially affected, or is reasonably likely to materially affect, our internal controls over financial reporting.

PART II. OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

     From time to time, the Company may become involved in claims and other legal matters arising in the ordinary course of business. On February 25, 2009, the Company received a Civil Investigative Demand (“CID”) from the Attorney General of the State of Missouri, in connection with its investigation into the Company’s pricing practices with respect to Acthar under Missouri’s Merchandising Practices Act. On May 7, 2009, the Company received a subpoena from the Attorney General of the State of New York, in connection with its investigation, under New York’s antitrust statute and Federal antitrust statutes, into the Company’s acquisition of Acthar from Aventis in 2001, the Company’s Acthar royalty arrangements and its subsequent pricing of Acthar. The Company has provided documents and information to the Attorney Generals of Missouri and New York. The Company intends to cooperate with those offices, as it has with respect to government inquiries of all types.

ITEM 1A. RISK FACTORS

     Biological products, like Acthar, require production processes that are more complicated than those required for chemical pharmaceuticals. Acthar is derived from the extraction and purification of porcine pituitary glands through complicated processes, and is difficult to manufacture. As such, manufacturing or testing failures could arise periodically and could result in production lots being rejected and the Company possibly having insufficient inventory. Additionally, the rejection of a production lot and the need to produce substitute lots could result in unanticipated charges or expenses. For example, in the quarter ended September 30, 2009, the Company reserved $500,000 for a manufactured lot of Acthar that did not meet applicable specifications.

     This Quarterly Report on Form 10-Q contains forward-looking statements that involve risks and uncertainties. The Company’s actual results could differ materially from those discussed herein. Factors that could cause or contribute to such differences include, but are not limited to:

	•		the Company’s ability to continue to successfully implement its Acthar-centric business strategy, including its expansion in the MS marketplace;
	•		the Company’s ability to manage its sales force expansion;
	•		FDA approval of and the market introduction of competitive products and the Company’s inability to market Acthar in IS prior to approval of IS as a labeled indication;
	•		the Company’s ability to operate within an industry that is highly regulated at both the Federal and state level;
	•		regulatory changes or actions including Federal or State health care reform initiatives;
	•		the Company’s ability to accurately forecast the demand for its products;
	•		the gross margin achieved from the sale of the Company’s products;
	•		the Company’s ability to estimate the quantity of Acthar used by government-supported entities and Medicaid-eligible patients;
	•		the actual amount of rebates and chargebacks related to the use of Acthar by government-supported entities, including the Department of Defense Tricare network, and Medicaid-eligible patients may differ materially from the Company’s estimates;
	•		the Company’s expenses and other cash needs for upcoming periods;
	•		the inventories carried by the Company’s distributors, specialty pharmacies and hospitals;
	•		volatility in the Company’s monthly and quarterly Acthar shipments and end-user demand;

	•		the Company’s ability to obtain finished goods from its sole source contract manufacturers on a timely basis if at all;
	•		the Company’s ability to attract and retain key management personnel;
	•		the Company’s ability to utilize its net operating loss carryforwards to reduce income taxes on taxable income;
	•		research and development risks, including risks associated with the Company’s sNDA for IS and its preliminary work in the area of nephrotic syndrome;
	•		uncertainties regarding the Company’s intellectual property;
	•		the uncertainty of receiving required regulatory approvals in a timely way, or at all; and
	•		uncertainties in the credit and capital markets and the impact a further deterioration of these markets could have on the Company’s investment portfolio.

     These and other risks are described in Part I, Item 1A of the Company’s Annual Report on Form 10-K for the year ended December 31, 2008.

     On February 29, 2008, the Company’s board of directors approved a stock repurchase plan that provides for the Company’s repurchase of up to 7 million of its common shares. The stock repurchase plan was publicly announced on March 3, 2008. On May 29, 2009, the Company’s board of directors increased the Company’s common share repurchase program authorization by an additional 6.5 million shares. The increase to the number of shares authorized under the stock repurchase plan was publicly announced on June 2, 2009. Stock repurchases under this program may be made through open market or privately negotiated transactions in accordance with all applicable laws, rules and regulations. The transactions may be made from time to time and in such amounts as management deems appropriate and will be funded from available working capital. The stock repurchase program does not have an expiration date and may be limited or terminated at any time by the board of directors without prior notice.
