1 DISCUSSION 2 These documents are proper subjects of judicial notice. The Court may take judicial 3 notice of and consider on a motion to dismiss documents filed with the SEC. See Janas v. 4 McCracken (In re Silicon Graphics Sec. Litig.), 183 F.3d 970, 983 (9th Cir. 1999); In re Nuko 5 Info. Sys. Sec. Litig., 199 F.R.D. 338, 341 (N.D. Cal. 2000). The above-referenced disclosure 6 statements, attached hereto as Exhibits A through N, constitute “relevant public disclosure 7 documents filed with the Securities Exchange Commission[.]” Ronconi v. Larkin, No. C-97- 8 1319, 1998 U.S. Dist. LEXIS 6364, *2 (N.D.Cal. May 1, 1998). Because it would be “highly 9 impractical and inconsistent with Fed. R. Evid. 201 to preclude a district court from considering 10 such documents when faced with a motion to dismiss a securities action based on allegations of 11 material misrepresentations or omissions,” this Court may take judicial notice of the SEC Forms 12 8-K, 10-QSB, 10-Q, 10-Q/A, 13D and 4 for purposes of this motion. Lovelace v. Software 13 Spectrum, Inc., 78 F.3d 1015, 1018 n.1 (5th Cir. 1996) (citation omitted); accord Fla. State Bd. 14 of Admin. v. Green Tree Fin. Corp., 270 F.3d 645, 663 (8th Cir. 2001).

enue, NW, Washington, DC, 20037 enue, NW, 15 The Court may also consider “the full text of documents cited by the plaintiffs” in the 16 Consolidated Complaint. Ronconi, 1998 U.S. Dist. LEXIS 6364, at *2; Silicon Graphics, 183 Blank Rome LLP 17 F.3d at 986. Thus, the Court may take judicial notice of the full text of the Form 8-Ks and press 18 releases referenced or quoted in the Complaint. In re Gilead Sciences Sec. Litig., 2005 WL 19 181885 at *3 (N.D. Cal. Jan. 26 2005); Wiestschner v. Monterey Pasta Co., 294 F. Supp. 2d, 20 1102, 1108-09 (N.D. Cal. 2003). In addition, the Court may take judicial notice of stock prices Watergate, 600 New Hampshire Av Watergate, 600 21 in ruling on a motion to dismiss. In re 3Com Sec. Litig., 199 WL 1039715 at *4 (N.D. Cal. July 22 8, 1999); Ravens v. Iftikar, 174 F.R.D. 651, 661 (N.D. Cal. 1997) (noting that the Court may, on 23 its own motion, take judicial notice of historical stock prices). 24 Although virtually all of the documents referred to in the Memorandum of Points & 25 Authorities in Support of Defendants’ Motion to Dismiss are quoted or cited in the Complaint, 26 documents upon which the Complaint is based can be considered irrespective of whether 27 plaintiff has chosen to cite or quote from them. In re Metricom Secs. Litig., 2004 U.S. Dist. 28

1 LEXIS 7834, *23-*24 (N.D. Cal. May 4, 2004);Wietschner, 294 F. Supp. 2d at 1109; see also In 2 re Burlington Coat Factory Sec. Litig., 114 F.3d 1410, 1426 (3d Cir. 1997) (“Plaintiffs cannot 3 prevent a court from looking at the text[] of the documents on which its claim is based by failing 4 to attach or explicitly cite to them.”); see also Parrino v. FHP, Inc., 146 F.3d 699, 705-06 (9th 5 Cir. 1998). 6 Therefore, the Court may take judicial notice of the historical stock price for Impax 7 attached hereto as Exhibit O, the documents relied on to determine the amount of stock and 8 options held by the defendants attached hereto as Exhibits G-L, as well as the press releases that 9 the plaintiffs cited or relied upon in the Complaint, attached hereto as Exhibits Q-W.

10 For the foregoing reasons, Defendants respectfully request that the Court take judicial 11 notice of each of the documents listed above. 12 Respectfully submitted, 13

3 NOTES TO FINANCIAL STATEMENTS Three Months Ended March 31, 2004 and March 31, 2003

Note 1. The financial statements included herein have been prepared by the Company pursuant to the rules and regulations of the Securities and Exchange Commission . Certain information and disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America have been condensed or omitted pursuant to such rules and regulations; however, the Company believes that the disclosures are adequate to make the information presented not misleading . These financial statements should be read in conjunction with the financial statements and the notes thereto included in the Company's latest Annual Report on Form 10-K . The results of operations for the three months ended March 31, 2004 are not necessarily indicative of the results of operations expected for the year ending December 31, 2004.

Impax Laborato ries, Inc. ("IMPAX, "we,"'tis," or "the Company") focuses on the development, manufacturing, and marketing of special ty pharmaceutical products utilizing its own formulation expertise and drug delivery technologies . As of March 31, 2004, the Company is marketin .* thirty-three generic pharmaceu ticals, which represent dosage varia tions of fourteen different pharmaceutical compounds , and has seventeen applications under review with the Food and Drug Administration (FDA), including five tentatively approved, addressing app roximately $5 .4 billion in U .S . product sales in the twelve months ended Februa ry 29, 2004, according to NDCHealth . Thirteen of these pending filings we re filed under Paragraph IV of the Hatch-Waxman Amendments . The Company has app roximately twenty-seven other products in various stages of development for which applications have not yet been filed. Th ese other products are generic versions of pharmaceutical products that had U .S. sales of approximately S 14.5 billion in the twelve months ended February 29, 2004 , according to NDCHealth .

Except for the three months ended March 31, 2004, we have experienced operating losses and negative cash flow from operations and our future profitability continues to be uncertain. As of March 31, 2004, our accumulated deficit was $95,501,000 and we had outstanding indebtedness in an aggregate principal amount of $16,608,000. To remain operational, we must, among other things :

• obtain FDA approval for our products ; • prevail in patent infringement li tigation in which we are involved;

• successfully launch our new products ; and comply with the many complex governmental regulati ons that deal with virtually eve ry aspect of our business activities. We expect to incur signi ficant operating expenses , pa rticularly for research and development, for the foreseeable future in order to execute our business plan. We , therefore, anticipate that such operating expenses , as well as planned capital expenditures, will constitute a material use of our cash resourc es.

On April 5, 2004, the Company completed a convertible senior subordinated debenture offering of $95,000,000 for net proceeds of $91 ,675,000. The proceeds of the debentures will be used for general corporate purposes, including working capital requi rements , manufactu ring of our products, and research and development .

To date, the Company has funded its research and development and other operating ac tivities through equity and debt financings and strategic alliances .

Critical Accounting Policy Related to Revenue Recognition

The Company recognizes revenue in accordance with SEC Staff Accounting Bulletin ("SAB") 101 issued by the SEC in December 1999. We recognize revenue from the sale of products when the shipment of p roducts is received and accepted by the customer . Provisions for estimated discounts, rebates, chargebacks , returns and other adjustments are provided for in the period the related sales are recorded . In December 2003, the SAB 104 was issued by the SEC. This bulletin revises and clarifies portions of Topic 13 of the Staff Accounting Bulle ti n to be consistent with current accounting and auditi ng guidance and SEC rules and regulations .

Emerging Issues Task Force (EITF) No. 00-21 supplemented SAB 101 for accounting for mul tiple element arrangements. Th e Company has entered into several strategic alliances that involve the delive ry of multiple products and se rvices over an extended pe riod of time . In multiple element arrangements, the Company must determine whether any or all of the elements of the arrangement can be separated from one another . If separation is possible, revenue is recognized for each deliverable when the revenue recogni tion criteria for the specific deliverable is achieved . If separation is not possible, revenue recognition is required to be spread over an extended period. Under EITF No . 00-21, in an arrangement with multiple elements, the delivered item should be considered a separate unit of accounting if all of the following criteria are met :

1) the delivered item has value to the customer on a standalone basis; 2) there is objective and reliable evidence of the fair value of the undelivered item; and

3) if the arrangement included a general right of return, or whether delivery or performance of the undelivered item is considered probable . The Company reviews all of the terms of its strategic alliances and follows the guidance from EITF No. 00-21 for multiple element arrangements.

In June 2001 , the Company entered into a Strategic Alliance Agreement with a subsidia ry of Teva for twelve controlled-release generic pharmaceutical products. Th e agreement granted Teva exclusive U .S. prescription marketing rights for these products for a period of ten years from the date of Teva's first sale of the products.

Revenues from product sales for these products under our strategic alliance are recognized at the time title and risk of loss transfers to Teva 's customers . During the three months ended March 31, 2004, the Company commenced shipping its Bup ropion Hydrochloride 100 mg and 150 mg Cont rolled Release Tablets. Teva ships the Bupropion products to its customers and reports the results on a monthly basis. Teva provides to IMPAX a financial repo rt detailing its g ross sales less applicable chargebacks , rebates and other credits to arrive at net sales, cost of sales information and gross margins for the Bup ropion products. Th e information on the fin ancial report is used by IMPAX to record its monthly revenue for the Bup ropion 100 mg and 150 mg products . Additionally, the amount of revenue that IMPAX cams is based on a fixed gross margin sharing percentage .

Under the July 2003 Exclusivity Transfer Agreement with Andrx and Teva pertaining to the Bupropion Hydrochloride products, Andrx is entitled to certain payments for the sales of the 150 mg strength for a 180-day period from the product launch date. These payments are made directly by Teva to Andrx.

Earnings Per Share

Basic earnings per share is computed by dividing net income by the weighted average common shares outstanding. Diluted earnings per share is based on the treasury stock method and is computed by dividing net income by the weighted average number of common shares and dilutive potential common shares outstanding, assuming the exercise of all in-the-money stock options . A reconciliation of the numerators and denominators of basic and diluted earnings per share consisted of the following ( in thousands, except per share amounts):

Three Months Ended March 31 ,

2004 2003

Numerator: Net income (loss) $ 9,048 $ (3,213 )

Denominator : Basic weighted average common shares outstanding 56,978,095 47,876,830 Effect of dilutive options and warrants 4,503,837 -

Fully diluted weighted average common shares outstandin g 61,481,932 47,876,830 Basic earnings per share S 0.16 S (0 .07)

Fully diluted earnings per share $ 0.15 S (0 .07)

Included in the computation of fully diluted earnings per share are outstanding stock options and warrants with an exercise price less than the average market price of the common shares for the period. As of March 31, 2004 there were no stock options or warrants excluded from the fully diluted earnings per share calculation because all options and warrants exercise pri ce were less than the average market p rice of common shares.

Stock-Based Employee Compensation

The Company accounts for stock-based employee compensation arrangements in accordance with provisions of Accounting Principles Board (APB) Opinion No . 25, "Accounting for Stock Issued to Employees ." Compensation cost for stock options, if any, is measured as the excess of the quoted market price of the stock at the date of grant over the amount an employee must pay to acquire the stock. The Company has adopted the disclosure only provisions of SFAS No . 123, "Accounting for Stock-Based Compensation" and SFAS No . 148, "Accounting for Stock- Based Compensation - Transition and Disclosure - An Amendment to FASB Statement No. 123 ." Back to Contents

Had compensation cost for the Company's Plans been determined based on the fair value at the grant dates for the awards under a method prescribed by SFAS No. 123, the Company' s income and income per share would have been decreased to the p ro forms amounts indicated below ( in thousands , except per share amounts):

Three Months Boded March 3 1 ,

Basic - pro forma $ 0.14 $ (0 .09)

Diluted - as reported $ 0.15 $ (0.07)

Diluted - p ro forms $ 0.13 $ (0.09)

The Company calculated the fair value of each option grant on the date of the grant using Black-Scholes pricing method with the following assumptions: for the three months ended March 31, 2004 and 2003 , the dividend yield was 0'/. and 0% ; the weighted average expected option term was five years ; risk-free interest rate was 3% and 2 .69%; the stock volatility for the three months ended March 31, 2004 and 2003 was 79 .48% and 69%, respectively. The weighted average fair value of op tions for March 31, 2004 and 2003 was $14 .12 and 51 .96, respec tively .

The Company reports both basic earnings per share, which is based on the weighted-average number of common shares outstanding, and diluted earnings per share, which is based on the weighted-average number of common shares outstanding and all dilu tive potential common shares outstanding .

Note 2. Convertible Senior Subordinated Debentures

On April 5, 2004, the Company issued and sold $95 .0 million in aggregate principal amount of its 1 .250%convertible senior subordinated debentures due 2024 . The debentures were sold by the Company to Citigroup Global Markets Inc ., Wachovia Capital Markets, LLC and First Albany Capital Inc., as initial purchasers , in a private placement exempt from registration under the Securities Act of 1933, as amended (the "Securities Act") . We have been advised by the initial purchasers that they have resold, and/or intend in the future to resell, the debentures to "qualified institutional buyers" (as defined in Rule 144A promulgated under the Securities Act) in transactions exempt from the registration requirements of the Securities Act in reliance on Rule 144A.

The issuance and sale of the debentures resulted in net proceeds to the Company of app roximately $91,675 ,000 . These proceeds are being used for general corporate purposes , including working capital requirements , manufacturing of our products and research and development.

The debentures bear interest at the rate of 1 . 250% per year. Interest on the debentures is payable on April I and October l of each year, beginning on October 1, 2004. The debentures are convertible by holders into shares of our common stock at a conversion p rice of $28 .08 per share (which represented a 300A premium over our stock p rice at the ti me the debentures were issued). The conversion price is subject to adjustment in certain events if. ( 1) the pri ce of our common stock reaches a specific threshold; (2) the trading price for the debentures falls below certain thresholds ; ( 3) the debentures have been called for redemp tion; or (4) certain corporate transactions occur. Back to Contents

The debentures mature on April 1, 2024, unless earlier redeemed, repurchased or converted. Before April 5 , 2007, we may redeem some or all of the debentures if the p rice of our common stock reaches a specific threshold, at a redemption price that includes an additional payment on the redeemed debentures equal to $230.77 per S 1,000 p rincipal amount of debentures , less the amount of any interest actually paid or accrued and unpaid on the debentures . On and after April 5, 2007, the Company may redeem some or all of the debentures at certain specified redemption prices.

Th e debentures are the Company 's unsecured obligations and are subordinated in right of payment to all of the Company's existing and future senior indebtedness. On April 1 , 2009 , April 1, 2014, and April 1, 2019, and under certain circumstances , holders of the debentures will have the right to require us to repurchase all or any part of their debentures at a repurchase price equal to 1009A of the principal amount of the debentures, plus accrued and unpaid interest and liquidated damages, if any, to, but excluding the repurchase date.

In connection with the offe ring of the debentures, we are required to file a shelf registra tion statement by July 5, 2004 with the Securities and Exchange Commission covering resales of the debentures and of the common stock issuable upon conversion of the debentures . Th e S-3 must be declared effective by the SEC by October 4, 2004.

Note 3. Recent Accounting Pronouncements

In November 2002, the EITF reached a consensus on Issue No . 00-21 . "Revenue Arrangements with Multiple Deliverables ." EITF Issue No. 00-2 1 T videa guidance on how to account for arrangements that involve the delivery or performance of multiple products, services, and/or rights to use assets. e Provisions of EITF Issue No . 00-21 applies to revenue arrangements entered into in fiscal periods beginning after June 15, 2003 . We implemented the provisions of EITF Issue No. 00-21 in revenue reco of certain strategic agreements . The Company reviews all of the terms of its strategic alliances and follows the guidance from this Issue for all multiple element arrangements.

In December 2002, the Financial Accounting Standards Board (FASB) issued SFAS No . 148, "Accounting for Stock-Based Compensation - Transition and Disclosure, amendment of FASB Statement No. 123 ." This statement provides additional transition guidance for those entities that elect to voluntarily adopt the provisions of SFAS No. 123, "Accounting for Stock Based Compensation."

However, the Company has adopted the disclosure provisions and has included this information in Note I to the Company's financial statements.

In January 2003, the FASB issued FASB Interpretation No . 46 ("FIN 46"), "Consolidation of Variable Interest Entities ." FIN 46 clarifies the application of Accounting Research Bulletin No. 51, "Consolidated Financial Statements," to certain entities in which equity investors do not have the characteristics of a controlling financial interest or do not have sufficient equity at risk for the entity to finance its activities without additional subordinated financial support from other parties . FIN 46 applies immediately to variable interest entities created after January 31, 2003, and to variable interest entities in which an enterprise obtains an interest after that date . It applies in the first fiscal year or interim period beginning after June 15, 2003, to variable interest entities in which an enterprise holds a variable interest that it acquired before February 1, 2003 . FIN 46 applies to public enterprises as of the beginning of the applicable interim or annual period . On October 8, 2003, the FASB decided to defer FIN 46 until the first reporting period ending after December 15, 2003 . The provisions of this Interpretation did not have a material impact on the Company's financial condition or results of operations .

In December 2003, the FASB issued FIN No . 46R, Consolidation of Variable Interest Entities, clarifying the application of Accounting Research Bulletin No. 51, Consolidated Financial Statements, to certain entities in which equity investors do not have the characteristics of a controlling financial interest or do not have sufficient equity at risk for the entity to finance its activities without additional subordinated financial support . The provisions of this Interpretation do not have a material impact on the Company' s financial condition or results of operations .

In February 2004, the FASB issued revised FASB Staff Position ("FSP") pertaining to FIN 46(R) . The revised FSPs replace certain previously issued FIN 46 FSP for entities to which FIN 46(R) is applicable . This revision to FIN 46 did not have a material impact on the Company's financial condition or results of operation.

In February 2004, the FASB revised SFAS 133, Accounting for Derivative Instruments and Hedging Activities for Implementation issue E2L, AIJ, and C6 . The revisions to SFAS 133 did not have a material impact on the Company's financial condition or results of operation .

Note 9. Commitments and Contingencies

Patent Litigation

There has been substantial litigation in the pharmaceutical, biological , and biotechnology industries with respect to the manufacture , use, and sale of new products that are the subject of conflicting patent rights. One or more patents cover most of the brand name cont rolled-release products for which we are developing generic versions. Under the Hatch-Waxman Amendments, when a drug developer files an ANDA for a gene ric drug, and the developer believes that an unexpired patent which has been listed with the FDA as covering that b rand name product will not be infringed by the developer 's product or is invalid or unenforceable, the developer must so certify to the FDA . That ce rtification must also be provided to the patent holder, who may challenge the developer's certification of non-infringement, invalidity or unenforceability by filing a suit for patent infringement within 45 days of the patent holder's receipt of such certification. If the patent holder files suit, the FDA can review and app rove the ANDA, but is prevented from granti ng final marketing approval of the product until a final judgment in the action has been rendered, or 30 months from the date the certification was received , whichever is sooner. Should a patent holder commence a lawsuit with respect to an alleged patent in fringement by us, the uncertainties inherent in patent litigation make the outcome of such litigation difficult to predict. The delay in obtaining FDA app roval to market our product candidates as a result of litigation, as well as the expense of such litigation, whether or not we are successful , could have a material adverse effect on our results of operations and financial posi tion . In addition , there can be no assurance that any patent li tigation will be resolved prior to the 30-month pe riod . As a result, even if the FDA were to app rove a product upon expiration of the 30-month period, we may not commence marketing that product if patent litigation is s till pending.

Lawsuits have been filed against us in connection with fourteen of our Paragraph IV filings . The outcome of such litigation is difficult to predict because of the uncertainties inherent in patent litigation .

As part of our patent litigation strategy, we had obtained two policies covering up to $7 million of patent infringement liability insurance from American International Specialty Line Company ("AISLIC"), an affiliate of AIG International. This litigation insurance covered us aga inst the costs associated with patent infringement claims made against us relating to seven of the ANDAS we filed under Paragraph IV of the Hatch-Waxman Amendments. Both policies have reached their limit of liability. While Teva has agreed to pay 45% to 50'% of the attorneys' fees and costs (in excess of the $7 million covered by our insurance policies) related to the twelve products covered by our strategic alliance agreement with Teva, we will be responsible for the remaining expenses and costs for these products, and all of the costs associated with patent litigation for our other products and our future products .

We do not believe that this type of litigation insurance will be available on acceptable terms for our current or future ANDAs. In those cases, our policy is to record such expenses as incurred.

Although the outcome and costs of the asserted and unasserted claims is difficult to predict because of the uncertainties inherent in patent litigation, management does not expect the Company's ultimate liability for such matters to have a material adverse effect on its financial condition, results of operations, or cash flows .

FIN 4 5 In November 2002, the FASB issued FIN No. 45, "Guarantor's Accounting and Disclosure Requirements for Guarantees, Including Indirect Guarantees of Indebtedness of Others." Guarantees and claims arise during the ordinary course of business from relationships with suppliers, customers, and strategic partners when the Company undertakes an obligation to guarantee the performance of others through the delivery of cash or other assets if specified tri ggering events occur . Non-performance under a contract by the guaranteed party triggers the obligation of the Company . As of March 31, 2004, all indemnifications included in agreements as of that date are excluded from the scope of FIN No . 45 as they relate primarily to our own future performance and do not require any contingent payments .

As of March 31, 2004, our total contractual commitments on loans , operating leases, and royalty agreements have not materially changed since December 31, 2003, as disclosed in our Report Form 10-K .

Note 10. Changes in Securities

As part of the strategic alliance agreement that we entered into with a subsidia ry of Teva Pharmaceutical Industries Ltd. (Teva) in June 2001, we received $22.0 million from Teva which assisted in the construction and improvement of our Hayward, Califo rnia facilities and the development of the twelve products specified in our strategic alliance agreement. The $22.0 million was reflected on the balance sheet as a refundable deposit. The refundable deposit was p rovided in the form of a loan. Pursuant to the agreement, accrued and future interest on the refundable deposit was forgiven during 2002 as a result of our receipt of tentative or final approvals for at least three of our products . In addition, Teva forgave portions of this loan as we achieved certain milestones relating to the development and launch dates of the products desc ribed in our strategic alliance agreement . In addition, by requiring us to repay only 50% of the portion of the loan related to certain missed milestones , Teva chose to continue to have exclusive marketing rights for those products . At our option, we could repay Teva any amounts we owed it as part of the loan in cash or in shams of our common stock . The price of the common stock for purposes of repaying any amounts owed under the loan was the average closing ale price of our common stock measured over a ten-trading-day period ending two days prior to repayment.

In September 2003, we issued 888,918 shares of common stock to Teva, paying $13 .5 million of the original $22 .0 million refundable deposit . In December 2003, Teva exercised its option to retain marketing exclusivi ty for certain products and, accordingly , reduced the refundable deposit by $3 .5 million to $5 .0 million . In Janua ry 2004 , Teva's exercise of the marketing exclusivi ty option for certain p roducts reduced the refundable deposit to $2 .5 million. On Janua ry 15, 2004 , we satis fied the remaining $2 .5 million refundable deposit obligation to Tevs by issuing 160,751 shares of our common stock to Teva. These shares were issued to Teva without registration under the Securi ti es Act of 1933, as amended, in reiance upon the exemption from registration provided by Section 4(2) of the Securities Act of 1933 .

On January 30, 2004, the holders of the Series 2 Preferred Stock converted their entire 75,000 preferred shares into 1,500,000 shares of common stock.

General

Impax Laboratories, Inc. was formed through a business combination on December 14, 1999 between Impax Pharmaceuticals, Inc ., a privately held drug delivery company, and Global Pharmaceutical Corporation, a generic pharmaceutical company . Impax Pharmaceuticals, Inc . merged with and into Global, with Impax stockholders receiving 3.3358 shares of Global common stock for each share of Impax Pharmaceuticals, Inc . At the conclusion of the merger, Impax Pharmaceuticals, Inc. stockholders held over 70%6 of the combined company. For accounting purposes, the merger has been treated as a recapitalization of Impax Pharmaceuticals, Inc. with Impax Pharmaceuticals, Inc . deemed the acquirer of Global in a reverse acquisition. As a reverse acquisition, our historical operating results prior to the merger are those of Impax Pharmaceuticals, Inc. and only include the operating results of Global after the merger. In connection with the merger, the surviving company changed its name to Impax Laboratories, Inc . Back to Contents

We are a technology based, specialty pharmaceutical company applying formulation and development expertise, as well as our drug delivery technology, to the development of controlled-release and niche generics, in addition to the development of branded products . As of March 31, 2004, the Company markets thirty- three generic pharmaceuticals, which represent dosage variations of fourteen different pharmaceutical compounds, and have seventeen applications pending at the FDA, including five tentatively approved, that address approximately $5.4 billion in U.S. product sales for the twelve months ended February 29, 2004, according to NDCHealth. Thirteen ofthese pending filings were made under Paragraph IV of the Hatch-Waxman Amendments . We have approximately twenty-seven other products in various stages of development for which applications have not yet been filed . These products are generic versions of pharmaceutical products that had U .S . sales of approximately $14 .5 billion for the twelve months ended February 29, 2004, according to NDCHealth .

Critical Accounting Poli cy Related to Revenue Recognition

The Company recognizes revenue in accordance with SEC Staff Accoun ting Bulletin ("SAB") 101 issued by the SEC in December 1999 . We recognize revenue from the sale of products when the shipment of products is received and accepted by the customer . Provisions for estimated discounts, rebates, chargebacks, returns and other adjustments are provided for in the period the related sales are recorded . In December 2003, the SAB 104 was issued by.the SEC. This bulletin revises and clarifies portions of Topic 13 of the Staff Accoun ting Bulletin to be consistent with current accounting and auditing guiance and SEC rules and regulations .

Emerging Issues Task Force (EITF) No. 00-21 supplemented SAB 101 for accounting for multiple element arrangements . The Company has entered into several strategic alliances that involve the delive ry of multiple products and services over an extended period of time . In multiple element arrangements, the Company must determine whether any or all of the elements of the arrangement can be separated from one another. If separation is possible, revenue is recognized for each deliverable when the revenue recognition c riteria for the specific deliverable is achieved. If separation is not possible , revenue recogni tion is required to be spread over an extended period .

Under EITF No . 00 -21, in an arrangement with multiple elements , the delivered item should be considered a separate unit of accounting if all of the following criteria are met:

1) the delivered item has value to the customer on a standalone basis ; 2) there is objective and reliable evidence of the fair value of the undelivered item; and 3) if the arrangement included a general right of return, or whether delivery or performance of the undelivered item is considered probable. The Company reviews all of the terms of its strategic alliances and follows the guidance from EITF No. 00-21 for multiple element arrangements.

In June 2001, the Company entered into a Strategic Alliance Agreement with a subsidiary of Teva for twelve controlled- release generic PharmaceuticaI products . The agreement granted Teva exclusive U .S. prescription marketing rights for these products for a period of ten years from the date of Teva's first sale of the products .

Revenues from product sales for these products under our strategic alliance are recognized at the time title and risk of loss transfers to Teva's customers. During the three months ended March 31, 2004, the Company commenced shipping its Bupropion Hydrochloride 100 mg and 150 mg Controlled Release Tablets . Teve ships the Bupropion products to its customers and reports the results on a monthly basis . Teva provides to IMPAX a financial report detailing its gross sales less applicable chargebacks, rebates and other credits to arrive at net sales, cost of sales information and gross margins for the Bupropion products . The information on the financial report is used by IMPAX to record its monthly revenue for the Bupropion 100 mg and 150 mg products . Additionally, the amount of revenue that IMPAX earns is based on a fixed gross margin sharing percentage. 12 Back to Contents

Under the July 2003 Exclusivity Transfer Agreement with Andrx and Teva pertaining to the Bup ropion Hydrochloride p roducts, Andrx is entitled to certain payments for the sales of the 150 mg strength for a 180-day period from the product launch date . These payments are made directly by Teva to Andrx.

Results of Operation s

Except for the three months ended March 31, 2004, we have incurred net losses in each quarter since our inception . We had an accumulated de ficit of $95,501 ,000 at March 31, 2004 .

THREE MONTHS ENDED MARCH 31, 2004 , COMPARED TO THREE MONTHS ENDED MARCH 31, 2003

Overview

The net income for the three months ended March 31, 2004, was $9,048,000 as compared to a net loss of $3 ,213,000 for the three months ended March 31, 2003.

Revenues

Revenues for the first quarter of 2004 were a record $38,853,000, up more than 240% compared with revenues of $11,425,000 in the prior year's first quarter . The year-over-year increase for the first quarter was primarily due to shipments of our generic versions of Wellbutrin® SR (Bupropion Hydrochloride) 100 mg and 150 mg Controlled Release Tablets, both of which were approved by the FDA during the quarter and represented approximately 61% of total re venues . During the quarter, upon approval from the FDA, we also commenced shipments of Demeclocycline Hydrochloride (Declomycin®) 150 mg and 300 mg Tablets .

Th e Company generated $3,031,000 of other revenues in the 2004 pe riod,as compared to $359,000 in the 2003 period. Other revenue for the 2004 period consisted of $2,500,000 from Teva, which represented the reversal of a portion of the refundable deposit for its exercise of the exclusivity option for certain products. The balance of $531 ,000 of other revenue represents revenues recognized pursuant to strategic a greements with Schering-Plough, Wyeth, and Novertis. The following table summarizes the activi ty in net revenues for the three months ended March 31, 2004 and 2003 :

2004 2003

Product sales S 41,552 S 14,153 Less : Rebates (I 120 Chargebacks (1 ,314) Product return reserve (1,781) (132) Other credits (681) (579)

Net sales 35,822 11,066 Revenue from reversal of refundable deposit from Teva 2,500 - Other Revenues 531 359

Total Revenues $ 38,853 S 11,425

The rebates, chargebacks, returns and other credits decreased for the three months ended March 31, 2004 to approximately 14% of product sales as compared to approximately 22% for the comparable period in 2003 . This decrease was mainly due to Bupropton Hydrochloride 100 mg and 150 mg Controlled Release Tablets, Loratadine, and Pseudoephedrine Sulfate (5mgtl20mg) 12-hour Extended Release Tablets which are exempt from rebates, chargebacks and other credits as per the agreements with Schering-Plough, Wyeth, and Novartis . The increase in the reserve for product returns was primarily due to returns for LIPRAM products. Product returns for the three months ended March 31, 2004 and 2003 were $922,000 and $132,000, respectively.

Cost of Sales

The cost of sales for the three months ended March 31, 2004, was S 18,550,000 as compared to $8,147,000 for the same period in 2003 . The overall increase in cost of sales was primarily due to the increase in cost of materials as a result of increased product sales, primarily from Bupropion Hydrochloride 100 mg and 150 mg Controlled Release Tablets .

13 Gross Margin

Gross margin for the three months ended March 31, 2004 was $20,303,000 as compared to $3 ,278,000 for the same period in 2003 . The g ross margin improvement was prima rily due to higher net product sales, such as Bup ropion Hydrochloride 100 mg and 150 mg Controlled Release Tablets and Demeclocycline Hydrochloride 150 and 300 mg Tablets and bigha revenue from strategic alliances , which include amortization of deferred revenue for up-front and milestone payments of $531,000, as compared to $359,000 in 2003. In addition, $2,500,000 of other revenues represented the reversal of a portion of the refundable deposit from Teva under the strategic alliance agreement for its exercise of the exclusivity option for certain products .

Research and Development Expenses

The research and development expenses for the three months ended March 31 , 2004 were $6,504,000 less reimbursements of S 11,000 by a subsidiary of Teva Pharmaceutical Industries, Ltd. under the Strategic Alliance Agreement signed in June 2001 , as compared to $3,755,000 less reimbursements of S 132,000 for the same period in 2003. The higher research and development expenditures in 2004 as compared to 2003 we re attributable to higher legal expenses related to patents and alleged patent infringement lawsuits , higher pe rsonnel costs, Active Pharmaceutical Ingredient (API) costs, clinical studies, and new product introduction costs.

Se ing Expenses

The selling expenses for the three months ended March 31, 2004 were $726,000 as compared to $568 ,000 for the same period in 2003 . The increase in selling expenses as compared to 2003 was primarily due to higher personnel costs.

General and Administrative Expenses

The general and administrative expenses for the three months ended March 31, 2004 were $3,351 ,000 as compared to $2,122,000 for the same pe riod in 2003 . The increase in general and administrative expenses as compared to 2003 was p rimarily due to higher professional fees, insurance premiums, and personnel costs.

Interest Incom e

Interest income for the three months ended March 31 , 2004 was $56,000 as compared to $42,000 for the same period in 2003 , primarily due to higher average cash equivalents for the quarter.

Interest Expense

Interest expense for the three months ended March 31, 2004 was $272,000 as compared to $231,000 for the same period in 2003 . The interest expense for 2004 relates p rimarily to the two Cathay Bank loans, and the revolving credit facility and term loan agreement with Wachovia Bank N .A. The following table summarizes the activity for the three months ended March 31, 2004 and 2003 :

2004 200 3

Income Taxes

In March 2004, the Company provided for income taxes of $476,000, or 5% of income before taxes, as compared to SO for the 2003 period . Such income tax provision reflects the partial reversal of the deferred income tax asset valuation allowance recognized in prior years . The valuation allowance was reduced to reflect the realization of federal and state net operating loss carryforwards that offset the current tax component of the income tax provision. At December 31, 2003, the Company had a net operating loss-carryforward totaling approximately $94,600,000, which expires from 2009 through 2023 . Net Income

The net income for the three months ended March 31, 2004, was $9,048,000 as compared to a net loss of $3,213,000 for the same period in 2003 . The net income for the three months ended March 31, 2004 was due primarily to the introduction of the Bupropion 100 mg and 150 mg products marketed by Teva, and Demeclocycline Hydrochloride 150 and 300 mg. Tablets. In addition, the other revenues of $3,031,000 contributed to the profitability for the quarter . Hack to Contents

Liquidity and Capital Resources

As of March 31, 2004, we had S 19,491,000 in cash and cash equivalents. Only $200,000 of the account balances are insured by the Federal Depository Insurance Company (FDIC). The balance of the Company' s cash equivalents are held in U.S . Treasury securities, which are not insured by the FDIC .

We generated cash in excess of our working capital requirements for the three months ended March 31, 2004 . Our cash flows provided by operations were a positive amount of $4,982,000, as compared to a negative amount of $871,000 in the prior year . This increase was primarily related to the change, year-over-year, in net income, partially offset by increases in working capital account balances . In addition, the remaining balance of the refundable deposit was satisfied by issuing 160,751 shares of common stock to Teva and by Teva's exercise of the exclusivity option for certain products . As of March 31, 2004, to our knowledge, Teve owns 2,511,752 shares of IMPAX common stock, or approximately 4 .3% of the outstanding stock.

The net cash provided by financing activities for the three months ended March 31, 2004, was approximately $1,029,000 consisting of the $1,985,000 net proceeds from issuance of common stock upon exercise of stock options and warrants, and net repayments of $956,000 primarily from the Wachovia credit facility.

Our capital expenditures for the three months ended March 31, 2004 were $2,025,000 as compared to $698,000 for the same period in 2003.

In December 2003 , the Company transferred the $25 million Loan and Security Agreement from Congress Financial Corporation to Wachovia Bank, N.A ., thereby securing lower interest and less restrictive borrowing terms. The revolving loan is collateralized by eligible accounts receivable and inventory, subject to sublimits and other terms , and the term loan is collateralized by machine ry and equipment, with a 60-month amor tization. In addition, a $10 million restricted cash account was established as collateral for this credit facility , to be reduced based on meeting certain cumulative positive cash flow targets. The interest rates for the revolving loans are prime rate plus 0 .75%, or eurodollar rate plus 2.75%, at our option, based on excess availability . The term loan has an interest rate of prime rate plus 1 .5%, or eurodollar rate plus 4%, at our option. As of March 31, 2004, we borrowed approximately $6,953,000 against the revolving credit line and $3,085,000 against the term loan. Th e borrowing availability under the revolving credit line changes daily based on eligible accounts receivable and inventory . The revolving credit facili ty and the term loan agreement have two financial covenants : one related to Adjusted Excess Availability, and the other one related to Capital Expenditures limits. At March 31, 2004, both financial covenants were met .

We have no interest rate or derivative financial instruments nor mate rial foreign exchange risks. We are also not party to any off-balance-sheet arrangements, other than operating leases .

We expect to incur signi ficant operati ng expenses, particularly research and development, for the foreseeable future in order to execute our business plan . We, therefore, anticipate that such operating expenses, as well as planned capital expenditures , will constitute a material use of our cash resources.

On April 5, 2004, the Company completed a convertible senior subordinated debenture offering of $95,000,000 for net proceeds of $91,675,000. The proceeds of the debentures will be used for general corporate purposes , including working capital requirements, manufacturing of our p roducts , and research and development.

To date, we have funded our research and development and other operating activities through equity and debt financing , and strategic alliances.

We have not paid any cash dividends on our common stock and we do not plan to pay any such cash dividends in the foreseeable future . We plan to retain any earnings for the operation and expansion of our business. Our loan agreements and our strategic agreement with Teva prohibit the payment of dividends without the other party's consent .

(For additional details, please see Note 2.) ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RIS K The Company 's cash and cash equivalents includes U.S. government and short term commercial paper stated at cost which approximates market value . The primary objective of the Company's investment ac ti vities is to preserve principal while, at the same time, maximize yields without signi ficantly increasing risk . To achieve this objective, the Company maintains its portfolio in a variety of high credit quality secu rities, including U .S. Government securities, treasu ry bills, and short-term commercial paper. One hundred percent of the Company 's portfolio matures in less than one year. The car rying value of the portfolio app roximates the market value at March 31 , 2004 . The Company's debt instruments at March 31, 2004, are subject to fix ed and variable interest rates and principal payments . We believe that the fair value of our fixed and variable rate long-term debt approximates their carrying value of approximately S 16.6 million at March 31 , 2004 . While changes in market interestrates may affect the fair value of our fixed and variable rate long-term debt, we believe the effect, if any, of reasonably possible near-term changes in the fair value of such debt on the Company 's financial statements will not be material.

We have no interest rate or derivative financial instruments nor material foreign exchange risks . We are also not party to any off-balance-sheet arrangements, other than operating leases.

ITEM 4 . CONTROLS AND PROCEDURE S Th e Company, under the supervision and with the participation of our management, including our principal executive officers and our principal financial officer, evaluated the effectiveness of the design and operation of our disclosure controls and procedures as of the end of the period covered by this report . Based on this evaluation, our principal executive officers and our principal financial officer concluded that our disclosure controls and procedures are effective in reaching a reasonable level of assurance that information required to be disclosed by us in the reports that we file or submit under the Securities Exchange Act of 1934, as amended, is recorded, processed, summarized, and reported within the time period specified in the Securities and Exchange Commission's rules and forms . The CEO and CFO also conducted an evaluation of internal control over financial reporting ("Internal Control") to determine whether any changes in Internal Controls occurred during the quarter that have materially affected, or which are reasonably likely to materially affect, Internal Controls.

Based on this evaluation, there has been no such change during the quarter covered by this report . A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met . Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs . Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within the Company have been detected. The Company conducts periodic evaluations of its internal controls to enhance, where necessary, its procedures and controls . Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detecte d

ITEM 1. LEGAL PROCEEDINGS Patent Litigatio n

There has been substantial litigation in the pharmaceutical , biological, and biotechnology industries with respect to the manufacture, use, and sale of new products that ere the subject of conflicting patent rights . One or more patents cover most of the brand name controlled-release products for which we are developing generic versions. Under the Hatch-Waxman Amendments, when a drug developer files an ANDA for a generic drug, and the developer believes that an unexpired patent which has been listed with die FDA as covering t at brand name product will not be infringed by the developer 's product or is invalid or unenforceable, the developer must so certify to the FDA . That certification must also be provided to the patent holder, who may challenge the developer's certification ofnon-infringement, invalidity or unenforceability by filing a suit for patent in fringement within 45 days of the patent holder's receipt of such certification . If the patent holder files suit, the FDA can review and approve the ANDA, but is prevented from granting final marketing approval of the product until a final judgment in the action has been rendered,or 30 months from the date the certification was received, whichever is sooner. Should a patent holder commence a lawsuit with respect to an alleged patent infringement by us, the uncertainties inherent in tent litigation make the outcome of such litigation difficult to predict . The delay in obtaining FDA approval to market our product candidates as a result of litigation , as well as the expense of such litigation, whether or not we are successful , could have a material adverse effect on our results of operations and financial position . In addition , there can be no assurance that any patent litigation will be resolved prior to the 30-month pe riod. As a result, even if the FDA were to app rove a product upon expiration of the 30-month period , we may not commence marketing that product if patent litigation is still pending.

Lawsuits have been filed against us in connection with fourteen of our Paragraph IV filings. The outcome of such litigation is difficult to predict because of the uncertainties inherent in patent litigation .

p The Omeprazole Cases

In May 2000, AstraZeneca AB and four of its related companies filed suit against IMPAX in the U.S. District Court in Wilmington, Delaware claiming that IMPAX's submission of an ANDA for Omeprazole Delayed Release Capsules , 10 mg and 20 mg, constitutes infringement of six U .S . patents relating to AstraZeneca's P rilosec product . The action seeks an order enjoining IMPAX from marketing Omeprazole Delayed Release Capsules, 10 mg and 20 mg until Feb ruary 4, 2014, and awarding costs and attorney fees. There is no claim for damages .

In February 2001, AstraZeneca and the same related companies filed the same suit against IMPAX in the same federal court in Delaware for infringement, based upon IMPAX's amendment to its ANDA adding 40 mg strength Omeprazole Delayed Release Capsules.

AstraZeneca filed essentially the same lawsuits against nine other gene ric pharmaceutical companies (Andrx, Genpharm, Cheminor, Kremers, LEK, Eon, Mylan, Apotex, and Zenith). Due to the number of these cases, a multidistrict li tigation proceeding, In re Omeprazole 10 m g , 20 mg, and 40 mg Delayed Released Capsules Patent Litigation, MDL-1291, has been established to coordinate pre-tr ial proceedings. Both lawsuits filed by AstraZeneca against IMPAX have been transferred to the multidistrict litigation. l8 Back to Contents

Early in the multidist rict litigation, the trial court ruled that one of the six patents-in-suit was not infringed by the sale of a gene ric omeprazole product and that certain other patents were invalid. These rulings effectively eliminated four patents from the trial of these infringement cases, although AstraZeneca may appeal these rulings as part of the overall appeal process in the case .

On October 11, 2002, after a trial involving Andrx , Genpharm, Cheminor, and Kremers, the trial judge handling the multidistrict litigation ruled on AstraZeneca's complaints that three of these four defendants (First Wave Defendants) infringed the remaining patents-in-suit. The trial judge ruled that three of the Fi rst Wave defendants , Andrx , Genpharm, and Cheminor, infringed the remaining two patents asserted by AstraZeneca in its complaints, and that those patents are valid until 2007. In the same ruling , the trial court ruled that the remaining First Wave Defendant, Kremers, did not infringe either of the remaining two patents. This defendant's formulation differed from the formulation used by the other First Wave Defendants in several respects . In mid-December 2003, the U.S. Court of Appeals for the Federal Circuit a ffirmed the October 2002 ruling in all respects . Subsequent peti ti ons for rehearing have been denied.

The formulation that IMPAX would employ in manufacturing its generic equivalent of omeprazole has not been publicly announced . IMPAX's formulation has elements that resemble those of other First Wave Defendants, but it also has elements that differ . Although the ruling by the trial court in the multidistrict litigation has a significant effect on the course of AstraZeneca's litigation a$sinst IMPAX, application of the trial court's opinion is not certain . IMPAX believes that it has defenses to AstraZeneca's claims of infringement, but the opinion rendered by the trial court in the First Wave cases makes the outcome of AstraZeneca's litigation against IMPAX uncertain .

Two of the remaining six defendants (Second Wave Defendants) filed Motions for Summary Judgment of Non-Infringement, based upon the October 2002 ruling. The trial court has deferred ruling on those motions until discovery is completed .

In December 2003, the trial court entered a new scheduling order gove rning pre-trial proceedings relating to the Second Wave Defendants, including IMPAX . The schedule for completion of the li tigation in the Second Wave, including AstraZeneca's litigation against IMPAX, now provides that all fact discovery (with certain exceptions) is complete. AstraZeneca 's expert reports on issues as to which it bears the burden of proof, including issues of alleged infringement , were produced on February 17, 2004. IMPAX's responsive expert reports will be completed by July 12 , 2004. Any rebuttal reports by AstraZeneca will be required to be produced by August 6, 2004. The parties have not submitted their joint schedule for expe rtdepositions to the Special Master and the S pecial Master has not issued an order regarding expert depositions. Depositions of the parties ' experts are expected to occur thereafter and to be completed by mid-December 2004 . Motions for Summary Judgment and responses must be filed and fully b riefed by November 18, 2004. Given the delays which have thus far occurred in the litiga tion and the number of experts already designated by the parties, it is uncertain whether the expert depositions can be completed in the time allotted by the present schedule.

Under the scheduling order, any further Motions for Summary Judgment must be filed by early Fall, and they will be heard by the trial court a fter briefing is completed in November 2004 . IMPAX may file Mo ti ons for Summary Judgment, including a Motion for Summary Judgment of Non-Infringement, following the close of all discovery. If the case is not resolved by summary judgment, the case involving IMPAX will be returned to the U.S. District Court in Delaware for trial. It is likely, given the proceedings in the First Wave cases, that the case against IMPAX will be transferred back to New York for a consolidated trial before the same judge who decided the First Wave cases . Trial will commence as soon as practicable thereafter. If IMPAX does not file a Motion for Summary Judgment , or if such a Motion is denied, the court will schedule a date for trial. IMPAX intends to vigorously defend the action brought by AstraZeneca.

In August 2003 , the court issued an order dismissing four of the patents -in-suit, three with prejudice. On September 30, 2003 , as a result of the court's dismissal, AstraZeneca se rved each of the Second Wave Defendants , including IMPAX, with an amended complaint. In October 2003 , IMPAX filed an answer to the amended complaint in which we asse rted a new counterclaim with antitrust allega tions. The counterclaim will be severed, and proceedings relating to it will be stayed until after trial of the patent infringement case.

GlaxoSmithKline (Glaxo) v. IMPAX: The Buproplon Cases

Glaxo filed a Complaint (Case No. 00-04403) against IMPAX in the U .S . District Court for the Northern District of California on November 3, 2000 alleging infringement of U .S. Patent No. 5,427,798 covering Wellbutrin SR and Zyban . On November 7, 2000, IMPAX filed its Answer to the Complaint which included defenses to the infringement claim, and counterclaimed for patent invalidity. Glaxo has filed suit against Andrx, Watson, Eon (only with regard to Wellbutrin SR) and Excel for similar ANDA filings. 19 Back to Contents

IMPAX filed a Summary Judgment Motion , based upon prosecution history estoppel grounds. The parties completed the briefing on this issue and oral argument was held on November 19, 2001 . At the request of the Court, in July 2002 , both sides submitted briefs on the impact of the recent Sup reme Court decision in Festo v . Shoketsu Kinzoku Kogyo Kabushi Co ., et al . (which we refer to as the Festo decision ) to the pending Motion for Summary Judgment. IMPAX brought an additional Mo ti on for Summary Judgment in early August 2002 , requesting that the court apply another court's decision which limited the scope of the Glaxo '798 patent .

On August 21, 2002 , IMPAX's Motions for SummaryJudgment were granted. Glaxo has appealed this decision to the Court of Appeals for the Federal Circuit and that appeal was fully b riefed on January 22, 2003. Oral argument was heard on June 2, 2003 and the District Court's decision in favor of IMPAX was affirmed by the Cou rt of Appeals on January 29, 2004. Glaxo has filed a request for rehearing or rehea ring en banc.

Previously, Olaxo had decided to settle its Bupropion Hydrochloride 100 mg and 150 mg Extended Release Tablets li tigation with Watson Pharmaceuticals on terms that are confidential.

Aventis Pharmaceuticals Inc .. et aL v.IMPAX: The Fexofenadlue Case s

On March 25 , 2002 , Aventis Pharmaceuticals Inc., Merrell Pharmaceuticals Inc ., and Carderm Capital L.P. (collectively referred to as Aventis) sued IMPAX in the U .S. District Court for the District of New Jersey (Civil Action No. 02-CV- 1322) alleging that IMPAX 's proposed fexofenadine and pseudoephedrine hydrochloride tablets , containing 60 mg of fexofenadine and 120 mg of paeudoephedrine hyd rochlo ride, infringe U.S. Patent Nos. 6,039,974; 6,037,353 ; 5,738 ,872 ; 6,187,791 ; 5,855 ,912; and 6,113,942 . On November 7, 2002, Aventis filed an amended complaint , which added an allegation that IMPAX's Fexofenadine and Pseudoephedrine Hydrochloride 60 mg/120 mg Extended Release Tablet product infringes U.S. Patent No. 6,399,632 . Aventis seeks an injunction preventing IMPAX from marketing its Fexofenadine and Pseudoephedrine Hydrochlo ride 60 mg/120 mg Extended Release Tablet product until the patents-in--suit have expired, and an award of damages for any commercial manufactu re, use, or sale of IMPAX's Fexofenadine and Pseudoephednne Hydrochlo ride 60 mg/120 mg Extended Release Tablet product, together with costs and a ttorneys' fees .

Fact discovery in this action is scheduled to close on October 29, 2004. IMPAX believes that it has defenses to the claims made by Aventis based on noninfringement and invalidity. No trial date has been set.

Aventis has also filed a suit against Barr Laboratories, Inc., Mylan Pharmaceuticals, Inc., Dr. Reddy's Pharmaceu ti cals and Teva Pharmaceuticals USA, Inc. in New Jersey asserting the same patent infringement against these defendants' proposed Fexofenadine and Pseudoephedrine or Fexofenadine p roducts. The IMPAX case has been consolidated for trial with the Barr, Mylan, Dr. Reddy and Teva cases.

On July 23, 2003, IMPAX filed Summary Judgment motions for non-infringement of U.S . Patent Nos. 6,039,974, 6,113,942, and 5,855,912 ; and for non-infringement and invalidity of U.S. Patent No. 5,738,872. Opposition papers were filed on August 11, 2003 . Reply papers were filed on September 24, 2003 . On October 24, 2003, IMPAX filed a brief discussing the impact of the recent Feato decision on their Motions for Summary Judgment of non-infringement . Oral argument for the Summary Judgment Motion regarding the '912, '942, and '974 patents was heard on November 3, 2003 . Oral argument for the Summary Judgment Motion regarding the '872 patent was heard on December 8, 2003 . IMPAX is currently awaiting a decision on these motions.

Purdue Pharma L.P. et al, v IMPAX: The Oxycodone Cases

On April 11, 2002, Purdue Pharma and related companies filed a complaint in the U .S. District Court for the Southe rn District of New York alleging that IMPAX's submission of ANDA No. 76-318 for 80 mg OxyContin Tablets infringes three patents owned by Purdue . The Purdue patents are U.S . Patent Nos. 4,861,598, 4,970,075 and 5 ,266,331 ; all directed to cont rolled release opi~formulations . On September 19, 2002, Purdue filed a second Infringement Complaint regarding IMPAX's 40 mg OxyContin generic product. On October 9, 2002 , Purdue filed a third Infringement Complaint regarding IMPAX's 10 mg and 20 m~ OxyContin generic products. IMPAX filed its answer and wtwterclaims in each case on October 3, 2003 . On November 25, 2003 , Purdue submitted then reply to our counterclaims . Purdue is seeking, among other things, a court order preventing IMPAX from manufacturing, using or selling any drug product that infringes the subject Purdue patents. IMPAX had disputed~juriadiction of the New York courts and brought an action for a Declaratory Judgment of Patent Invalidity in Delaware . The New York court denied IMPAX s Motion to Dismiss and the Delaware action was dismissed.

Purdue previously sued Boeh ringer Ingelheim/Roxane, Endo and Teva on the same patents . One or more of these defendants may resolve the invalidity issues surrounding the Purdue patents prior to IMPAX' s case goes to trial. The Boehringer Ingelheim/Roxane suit is stayed. The Endo action was t ried in June 2003 and post trial b riefs have been filed. In January 2004, the judge in the Endo action ruled that the three patents in suit, the same patents that Purdue had asserted against IMPAX, are unenforceable because they were inequitably procured and enjoined their enforcement . There can be no assurances that such ruling will not be challenged or, if sustained upon challenge , that the rulings in IMPAX's cases will be consistent with such rulings . 20 Back to Contents

IMPAX Y. Aventis Pharmaceuticals . Inc. The Riluzole Cas e

In June 2002, IMPAX filed suit against Aventis Pharmaceuticals, Inc . in the U .S . District Court in Wilmington, Delaware, seeking a declaration that the filing of an ANDA to engage in a commercial manufacture and/or sale of Riluzole 50 mg Tablets for treatment of patients with amyotrophic lateral scleroses (ALS) does not infringe claims of Aventis' U .S. Patent No. 5,527,814 ('814 patent) and a declaration that this patent is invalid .

In response to IMPAX's complaint, Aventis filed counterclaims for direct infringement and inducement of infringement of the '814 patent. In December 2002, the distri ct court granted Aventis ' Motion for Preliminary Injunction and enjoined IMPAX from in fringing , contributory infringm$, or inducing any other person to infringe Claims 1, 4 or 5 of the '814 patent by selling, offering for sale, distribu ting, marketing or exporting from the United States any pharmaceutical product or compound containing riluzole or salt thereof for the treatment of ALS .

The t rial was completed on October 30, 2003 , and post-trial briefing was completed in December 2003 . IMPAX is pursuing its assertions that claims of the '814 patent are invalid in view of prior art and are unenforceable in view of inequitable conduct committed during the p rosecution of the patent before the United States Patent and Trademark Office (USPTO) .

On January 30, 2004, the court denied IMPAX 's Motion for Summary Judgment on inequitable conduct and, on February 5, 2004 , the court denied IMPAX 's Motion for Summary Judgment on non-infringement of certain claims . The court has not issue its trial rulings and did not rule on the third pre-trial Motion for Summary Judgment based on invalidity of the patent-in-suit.

If IMPAX is not ultimately successful in proving invalidity or unenforceability, there is a substantial likelihood that the court will enter a Permanent Injunction enjoining IMPAX from marketing Riluzole 50 mg Tablets for the treatment of ALS in the United States until the ex pira tion of the '814 patent (June 18, 2013). If IMPAX is ultimately successful in proving either defense , the Preliminary Injunction would be set aside and IMPAX would be permitted to market its Riluzole 50 mg Tablet product for the treatment of ALS in the United States.

Abbott Laboratories Y. IMPAX : The Feno llbrate Tablet Case s

In January 2003 , Abbott Laborato ries and Fournier Industrie et Sante and a related company filed suit against IMPAX in the U .S. District Court in Wilmington , Delaware claiming that IMPAX 's submission of an ANDA for Fenofibrate Tablets , 160 mg, constitutes infringement of two U.S. patents owned by Fournier and exclusively licensed to Abbott, relating Abbott's Tricor tablet product.

In March 2003 , Abbott and Fournier filed a second action against IMPAX in the same court making the same claims against IMPAX 's 54 mg Fenofibrate Tablets . These cases were consolidated in April 2003 .

In September 2003, Abbo tt and Fournier filed a third action against IMPAX in the U.S. District Court in Wilmington , Delaware , claiming that IMPAX's submission of its ANDA for 54 mg and 160 mg Fenofibrate Tablets cons ti tutes infringement of a third patent recently issued to Fou rnier and exclusively licensed to Abbott. This action was also consolidated with the two previously consolidated actions in December 2003 . In January 2004, Abbott and Fournier filed a fourth action relating to IMPAX's 54 mg and 160 mg Fenofibrate Tablets based u pon a claim of in fringement of a fourth patent. All four cases were consolidated in March 2004 . Discovery in the consolidated cases closes in June 2004 and the trial is currently set for June 2005 . IMPAX has responded to all four complaints by asser ti ng that its proposed generic Fenofibrate Tablet products do not infringe the patents-in-suit and by asserting that the patents-in-suit are invalid .

All four actions seek an injunc ti on preventing IMPAX from marketing its Fenofibrate Tablet products until the expiration of the patents (January 9, 2018) and an award of damages for any commercial manufacture , use, or sale of IMPAX 's Fenofibrate Tablet product, together with costs and attorney fees.

Solvay Pharmaceuticals Y. IMPAX : The Croon Case

On April 11, 2003, Solvay Pharmaceuticals , Inc ., manufacturer of the Croon line pancreatic enzyme products, brought suit against IMPAX in the U .S. District Court for the District of Minnesota claiming that IMPAX has engaged in false advertising , unfair competition, and unfair trade practices under federal and Minnesota law in connec ti on with the Company's marketi ng and sale of its Lipram products . The suit seeks actual and consequential dame es, including treble damages, atto rneys' fees, injunctive relief and declaratory judgments that would prohibit the subs titution of Lipram for prescriptions of Croon . On June 6, 2003, IMPAX filed a Moti on for Dismissal of Plaintiff's Complaint, which seeks to dismiss each count of Solvay's complaint. Oral argument on that Motion was heard on November 7, 2003 . On Janua ry 9, 2004, the U.S . District Cou rt issued a ruling on IMPAX 's Motion for Dismissal, dismissing two of the counts set forth in the Complaint, including the count which sought a declaratory judgment that Lipram may not lawfully be substituted for prescriptions of Croon. On Janua ry 26, 2004, IMPAX filed its Answer to the Complaint and Counterclaim alleging that Solvay w rongfully interfered with IMPAX 's business relationships. On February 17, 2004 , Solvay filed its Reply to IMPAX' s Counterclaim . On February 24, 2004, the Rule 16 Scheduling Conference was held and, on Februa ry 25, 2004, the Court issued a Scheduling Order setting the deadline for discovery on January 14, 2005, and a trial date for July 1, 2005 . Fact discovery is currently ongoing in this case. IMPAX believes it has defenses to Solvay's allega ti ons and intends to pu rsue these defenses vigorously. 21 Back to Contents

Aiza Corporation v . IMPAX : The Oxybutynln Case

On September 4, 2003, Alza Corporation ("Alza") filed a lawsuit against IMPAX in the U .S . District Court for the Northern District of California alleging patent in fringement of one patent related to IMPAX's filing of an ANDA for a generic version of Ditropan XL (Oxybutynin Chloride) Tablets, S mg, to mg, and 15 mg. Alta seeks an injunction, a declaration of infringement, attorney's fees and costs. On October 24, 2003, IMPAX filed its Answer to the Complaint , which included defenses to the infringement claim, and counterclaimed for patent non-infringementand invalidity.

On October 24, 2003, IMPAX filed a lawsuit against Alza in the U.S. District Court for the Northern District of California seeking a declaratory judgment that four Alza patents relating to IMPAX's filing of an ANDA for a generic version of Ditropan XL (Oxybutynin Chloride) Tablets, 5 mg, 10 mg, and 15 mg (the "Product") are invalid and/or not infringed by the commercial manufacture, use, offer for sale, sale, or importation of the IMPAX Product . On November 17, 2003, AIm moved to dismiss the Company's complaint for lack of subject matter jurisdiction based on Alza' s argument that there is no can or controversy between the parties with respect to these four patents. The U.S. District Court for the Northern District of California has ordered a mediation on June 20, 2004.

: The Adderall Case

On December 29, 2003, Shire Laboratories, Inc., a subsidiary of Shire Pharmaceuticals Group , PLC, filed a lawsuit against IMPAX in the U .S. Dist rict Court for the District of Delaware alleging patent infringement on U.S. Patent Nos. 6,322 ,819 and 6,605,300 related to filing of an ANDA to market a generic version of Adderall 30 mg capsules .

OTHER LITIGATIO N

State of California v. IMPAX

On August 7, 2003, IMPAX received an Accusation from the Department of Justice , Bureau of Narcotic Enforcement, State of California ("BNE"), alleging that IMPAX failed to maintain adequate con trols to safeguard precursors from theft or loss regarding our pseudoephedrine product in January 2003. IMPAX contested the allegations in the Accusation and entered into discussions with the State of California, Department of Justice , to bring resolution to this matter. IMPAX has implemented a number of remedial measures aimed at imp roving the security and accountability of precursor substances used by IMPAX and regulated by the Califo rnia Department of Justice , Bureau of Narcotic Enforcement. In March 2004, following a theft of pseudoephedrine from IMPAX's facilities, the BNE filed an Amended Accusation, again alleging that IMPAX failed to maintain adequate controls to safeguard precursors from theft or loss regarding our pseudoephedrine product. IMPAX is continuing its discussions with the State of California, Department of Justice , and hopes to resolve this matter without the need for a formal hearing.

Other than the legal proceedings desc ribed above, we are not aware of any other material pending or threatened legal actions , private or governmental, against us. However, as we file additional applications with the FDA that contain Paragraph IV Certifica ti ons and develop new products, it is likely we will become involved in additional litigation related to those filings or products .

Insurance

As part of our patent litigation strategy, we had obtained two policies covering up to $7 million of patent infringement liability insurance from American International Specialty Line Company ("AISLIC"), an affiliate of AIG International . This litigation insurance covered us against the costs associated with patent infringement claims made against us relating to seven of the ANDAs we filed under Paragraph IV of the Hatch-Waxman Amendments . Both policies had reached their limits of liability. While Teva has agreed to pay 45% to SOV. of the attorneys' fees and costs (in excess of the $7 million expected to be covered by our insurance policies for six products) related to the twelve products covered by our strategic alliance agreement with them, we will be responsible for the remaining expenses and costs for these products, and all of the costs associated with patent litigation for our other products and our future products . However, we do not believe that this type of litigation insurance will be available to us on acceptable terms for our other current or future ANDAs . In those cases, our policy is to record such expenses as incurred.

Product liability claims by customers constitute a risk to all pharmaceutical manufacturers . We carry $20 million of product liability insurance for our own manufactured products. This insurance may not be adequate to cover any product liability claims to which we may become subject. 22 ITEM 2. CHANGES IN SECURITIES, USE OF PROCEEDS AND ISSUER PURCHASES OF EQUITY SECURITIES 1.250% Convertible Senior Subordinated Debentures

On April 5 , 2004, the Company issued and sold $95 .0 million in aggregate p rincipal amount of its 1 .250% convertible senior subordinated debentures due 2024. The debentures were sold by the Company to Citi $roup Global Markets Inc., Wachovia Capital Markets, LLC and First Albany Capital Inc ., as initial purchasers, in a p rivate placement exempt from registration under the Securi ties Act of 1933 , as amended (the "Securities Act") . We have been advised by the initial purchasers that they have resold, and/or intend in the future to resell, the debentures to "qualified institutional buyers " (as defined in Rule 144A promulgated under the Secur ities Act) in transactions exempt from the registration requirements of the Securities Act in reliance on Rule 144A.

The issuance and sale of the debentures resulted in net proceeds to the Company of approximately $91,675,000 . These proceeds are being used for general corporate purposes , including working capital requirements , manufacturing of our products and research and development.

The debentures bear interest at the rate of 1 .250% per year. Interest on the debentures is payable on Ap ril 1 and October 1 of each year, beginning on October 1, 2004. The debentures are convertible by holders into shares of our common stock at a conversion p rice of $28 .08 per share (which represented a 30% premium over our stock price at the time the debentures were issued). The conversion price is subject to adjustment in certain events if (1) the p rice of our common stock reaches a specific threshold; (2) the trading price for the debentures falls below certain thresholds ; (3) the debentures have been called for redemption; or (4) certain corporate transac tions occur.

The debentures mature on Ap ril 1, 2024, unless earlier redeemed, repurchased or converted. Before April 5, 2007 , we may redeem some or all of the debentures if the price of our common stock reaches a speci fic threshold , at a redempti on p rice that includes an additional payment on the redeemed debentures equal to $230 .77 per S 1,000 principal amount of debentures, less the amount of any interest actually paid or accrued and unpaid on the debentures . On and after April 5 , 2007 , the Company may redeem some or all of the debentures at certain specified redemption prices .

The debentures are the Company's unsecured obli gations and are subordinated in right of payment to all of the Com pany's existing and future senior indebtedness. On April 1, 2009, April 1, 2014 , and April 1, 2019, and under certain circumstances , holders of the debentures will have the right to require us to repurchase all or any part of their debentures at a repurchase price equal to 100% of the principal amount of the debentures, plus accrued and unpaid interest and liquidated damages, if any, to, but excluding the repu rchase date.

In connection with the offe ring of the debentures, we are required to file a shelf registra tion statement with the Securities and Exchange Commission covering resales of the debentures and of the common stock issuable upon conversion of the debentures .

Strategic Alliance Agreement with Tev a

As part of the strategic alliance agreement that we entered into with a subsidia ry of Teva Pharmaceutical Industries Ltd. (Teva) in June 2001 , we received $22.0 million from Teva which assisted in the construction and improvement of our Hayward, California facilities and the development of the twelve products specified in our strategic alliance agreement. The $22 .0 million was reflected on the balance sheet as a refundable deposit. The refundable deposit was provided in the form of a loan . Pursuant to the agreement, accrued and future interest on the refundable deposit was forgiven during 2002 as a result of our receipt of tentative or final approvals for at least three of our products . In addi tion, Teva forgave portions of this loan as we achieved certain milestones relating to the development and launch dates of the p roducts desc ribed in our strategic alliance agreement . In addition, by requiring us to repay only 50% of the portion of the loan related to certain missed milestones , Teva chose to continue to have exclusive marke ting rights for those p roducts . At our option, we could repay Teva any amounts we owed it as part of the loan in cash or in shares of our common stock . The price of the common stock for purposes of repaying any amounts owed under the loan was the average closing sale p rice of our common stock measured over a ten -trading-day period ending two days prior to repayment.

In September 2003, we issued 888 ,918 shares of common stock to Teva, paying $13 .5 million of the orig inal $22.0 million refundable deposit. In December 2003 , Teva exercised its opti on to retain marketing exclusivity for certain products and, accordingly,reduced the refundable deposit by $3 .5 million to $5 .0 million . In Janua ry 2004 , Teva 's exercise of the marketing exclusivity option for certain p roducts reduced the refundable deposit to $2 .5 million . On January 15, 2004 , we satisfied the remaining $2 .5 million refundable deposit obligation to Teve by issuing 160,751 shares of ourcommon stock to Tevs . These shares were issued to Teva without registration under the Securi ti es Act of 1933, as amended, in reliance upon the exemption from registra ti on provided by Section 4(2) of the Securities Act of 1933. 23 ITEM 6 .

3 NOTES TO CONDENSED FINANCIAL STATEMENTS Six Months Ended June 30, 2004 and June 30, 2003 (unaudited)

Note 1 . These condensed financial statements included he rein have been prepared by the Company pursuant to the rules and regulations of the Securities and Exchange Commission. Certain informati on and disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of Ame rica have been condensed or omitted pursuant to such rules and regulations; however, the Company believes that the disclosures are adequate to make the information presented not misleading. These financial statements should be read in conjunction with the financial statements and the notes thereto included in the Company s latest Annual Report on Form 10-K. The results of operations for the six months ended June 30, 2004 are not necessarily indicative of the results of ope rations expected for the year ending December 31, 2004 .

Impax Laboratories, Inc. ( IMPAX, we, us, or the Company ) focuses on the development, manufacturing,and marke ti ng of specialty pharmaceutical products utilizing its own formulation expertise and drug delivery technologies . As of June 30, 2004, the Company is marketing thirty -three generic pharmaceuticals, which represent dosage variations of fourteen diffe rent pharmaceutical compounds, and has fourteen applications under review with the Food and Drug Administration (FDA), including five tentatively approved. Eleven of these pending filings were filed under Paragraph IV of the Hatch -Waxman Amendments. The Company has approximately twenty-four other products in various stages of development for which applications have not yet been filed.

Except for the six months ended June 30, 2004 , we have experienced operating losses and our future p rofitability continues to be uncertain . We have also experienced negati ve cash flow from operations. As of June 30, 2004 , our accumulated deficit was $94,929 ,000 and we had outstanding indebtedness in an aggregate principal amount of S 108,422,000. To remain operational , we must, among other things:

• obtain FDA approvals for our products ; • prevail in patent infringement litigation in which we are involved ; • successfully launch our new products; and comply with the many complex gove rnmental regulations that deal with virtually every aspect of our business ac tivities. We expect to incur significant operat ing expenses , particularly for research and development , for the fo reseeable future in order to execute our business plan. We, therefore, an ticipate that such operating expenses, as well as planned capital expenditures for the next twelve months , of $18 to $22 million, primarily in plant capacity expansion, will constitute a mate rial use of our cash resources .

To date, the Company has primarily funded its resea rch and development and other operating ac tivities through equity , debt financings and strategic alliances .

Critical Accounting Policy Related to Revenue Recogni tion

The Company recognizes revenue in accordance with SEC Staff Accoun ting Bulle ti n (SAB ) 101 issued by the SEC in December 1999. We recognize revenue from the sale of products when the shipment of products is received and accepted by the customer . Provisions for estimated discounts, rebates, chargebacks, retu rns and other adjustments are provided for in the period the related sales are recorded. In December 2003 , the SAB 104 was issued by the SEC . This bulletin clarifies portions of Topic 13 of the Staff Accoun tingBulletin to be consistent with current accoun ting and auditing guidance and SEC rules and regulations, and revises accounting guidance contained in SAB 101 related to mul tiple element revenue arrangements of Emerging Issues Task Force (EITF) No. 00-21 superseded as a result of the issuance .

Emerging Issues Task Force (EITF) No. 00-21 supplemented SAB 101 for accounting for multiple element arrangements . The Company has entered into several s trategic alliances that involve the delivery of multiple products and services over an extended period of ti me . In multiple element arrangements, the Company must determine whether any or all of the elements of the arrangement can be separated from one another. If separation is possible, revenue is recognized for each deliverable when the revenue recognition criteria for the specific deliverable is achieved . If separation is not possible,revenue recognition is required to be spread over an extended pe riod.

Under EITF No. 00-21, in an arrangement with multiple elements , the delivered item should be considered a separate unit of accounting if all of the following criteria are met :

1) the delivered item has value to the customer on a standalone basin; 4 to Contents

2) there is objective and reliable evidence of the fair value of the undelivered item; and

3) if the arrangement included a general right of return, or whether delivery or performance of the undelivered item is considered p robable. The Company reviews all of the terms of its strategic alliances and follows the guidance from SAB 104 and EITF No. 00-21 for multiple element arrangements. Upfront and milestone payments from these strategic alliances are deferred and recognized over the life of the agreements as the Compan y fulfills its contractual obligation to manufacture and supplies products during this pe riod. In addi tion, in some agreements, the Company receives and records royalty revenue based on a percentage of the strategic partners total sales to their customers of the products supp lied by IMPAX .

In June 2001, the Company entered into a Strategic Alliance A greement with a subsidiary of Teva for twelve controlled-release generic pharmaceutical products . The agreement granted Teva exclusive U .S. prescription marketing rights for these products for a period of ten years from the date of Teva s first sale of the products .

Revenues from product sales for these products under our strategic alliance are recognized at the time ti tle and risk of loss transfers to Teva s customers. During the six months ended June 30, 2004, the Company commenced shipping its Bup ropion Hydrochloride 100 mg and 150 mg Controlled Release Tablets. Teva ships the Bupropion products to its customers and reports the results on a monthly basis. Teva provides to IMPAX a financial report detailing its gross sales less applicable char gebacks , rebates and other credits to arrive at net sales , cost of sales information and gross margins for the Bupropion products. The information on the financial report is used by IMPAX to record its monthly revenue for the Bupropion products. Additionally , the amount of revenue that IMPAX ears is based on a fixed gross margin sharing percentage.

Under the July 2003 Exclusivity Transfer Agreement with Andrx and Teva pertaining to the Bup ropion Hydrochlo ride products, Andrx is entitled to certain payments for the sales of the 150 mg strength for a 180-day period from the product launch date. These payments are made directly by Teva to Andrx .

Earnings Per Share (EPS)

Basic earnings per share is computed by dividing net income by the weighted average common shares outstanding . Diluted earnings per share is based on the treasury stock method and is computed by dividing net income by the weighted average number of common shares and dilutive potential common shares outstanding, assuming the exercise of all in-the-money stock options . A reconciliation of the numerators and denominators of basic and diluted ea rnings per share consisted of the following (in thousands, except per share amounts) :

Basic earnings per share $ 0 .01 $ (0.05) $ 0.17 $ (0.11)

Fully diluted earnings per share $ 0.01 $ (0.05) $ 0.16 S (0.11)

Included in the computation of fully diluted earnings per share are outstanding stock options and warrants with an exercise price less than the average market price of the common shares for the period.

Excluded from the computation of diluted earnings per share are outatandina common stock options with an exercise price greater than the average market price of the common shares for the period reported. For the three month period ended June 30, 2004, excluded from the computation of diluted earnings per sham were stock options to purchase 969,389 common shares. For the six month period ended June 30.2003, excluded from the computation of diluted earnings per share were stock options to purchase 969,389 common shares.

5 Th e effect of approximately 3 .4 million shares related to the assumed conversion of the S95 million convertible senior subordinated debentures has been excluded from the computation of diluted earnings per share for the three and six months ended June 30, 2004 as none of the conditions that would permit conversion have been satisfied.

Stock-Based Employee Compensation

The Company accounts for stock-based employee compensation arrangements in accordance with provisions of Accounting Principles Board (APB) Opinion No . 25, Accounting for Stock Issued to Employees. Compensation cost for stock options, if any, is measured as the excess of the quoted market price of the stock at the date of grant over the amount an employee must pay to acquire the stock. The Company has adopted the disclosure only provisions of SFAS No. 123, Accounting for Stock-Based Compensation and SFAS No . 148, Accounting for Stock-Based Compensation - Transition and Disclosure - An Amendment to FASB Statement No . 123 .

Had compensation cost for the Company s Plans been determined based on the fair value at the grant dates for the awards under a method prescribed by SFAS No. 123, the Company a income and earnings per share would have been decreased to the pro forma amounts indicated below (in thousands, except per share amounts):

The Company calculated the fair value of each option grant on the date of the grant using Black -Scholes pricing method with the following assumptions : for the six months ended June 30, 2004 and 2003 , the dividend yield was 0% and 0% ; the weighted average expected option term was five years; risk-free interest rate was 3.5% and 2.8% ; the stock volatility for the six months ended June 30, 2004 and 2003 was 78% and 69%, respectively. The weighted average fair value of options for June 30, 2004 and 2003 was $14.17 and $2.87, respectively.

The Company reports both basic earnings per share , which is based on the weighted-average number of common shares outstanding, and diluted earnings per share, which is based on the weighted- average number of common shares outstanding and all dilutive potential common shares outstanding .

Note 2. Convertible Senior Subordinated Debentures

On April 5, 2004, the Company issued and sold 595.0 million in gate principal amount of its 1 .250% convertible senior subordinated debentures due 2024 . The debentures we re sold by the Company to Citigroup Global Markets Inc ., Wachovia Capital Markets, LLC and First Albany Capital Inc., as initial purchasers, in a private placement exempt from registration under the Securities Act of 1933, as amended (the Securities Act ). We have been advised by the initial purchasers that they have resold , and/or intend in the future to resell, the debentu res to qualified institutional buyers (as defined in Rule 144A promulgated under the Securities Act) in transactions exempt from the registration requirements of the Securities Act in reliance on Rule 144A. 6 The issuance and sale of the debentures resulted in net proceeds to the Company of approximately $91,388,000. These proceeds are being used for general corporate purposes, including working capital requirements, manufacturing of our products and research and development.

The debentures bear interest at the rate of 1 .250% per year . Interest on the debentures is payable on April I and October 1 of each year , be#inning on October 1, 2004 . The debentures are convertible by holders into shares of our common stock at a conversion price of $28.08 per share (which are subject to adjustment upon certain events , but represented a 30% premium over our stock p rice at the time the debentures were issued). The debentures are convertible by holders into shares of our common stock if. (1) the price of our common stock reaches a specific threshold; (2) the trading price for the debentures falls below certain thresholds; (3) the debentures have been called for redemption; or (4) certain corporate transactions occur.

The debentures mature on April 1, 2024, unless earlier redeemed, repurchased or converted. Before April 5, 2007 , we may redeem some or all of the debentures if the price of our common stock reaches a specific threshold, at a redemption price that includes an additional payment on the redeemed debentures equal to $230.77 per $1,000 principal amount of debentures, less the amount of any interest actually paid or accrued and unpaid on the debentures. On and after April 5, 2007, the Company may redeem some or all of the debentures at certain speci fied redemption prices.

The debentures are the Company s unsecured obligations and are subordinated in right of payment to all of the Company s existi ng and future senior indebtedness. On April 1, 2009, April 1, 2014, and April 1, 2019, and under certain circumstances, holders of the debentures will have the right to require us to repurchase all or any part of their debentures at a repurchase price equal to 100% of the principal amount of the debentures , plus accrued and unpaid interest and liquidated damages , if any, to, but excluding the repurchase date .

In June 2004, the FASB discussed EITF 04-08, The Effect of Contingently Conver tible Debt on Diluted Earnings Per Share. The EITF task force has proposed that companies count the shares that could be issued upon conversion of secu rities like the Company s debentures when calculating fully diluted per share earnings . Had EITF 04-08 been effective as of June 30, 2004, the Company s income and earnings per share would have been as indicated below:

Note 3. Recent Accounting Pronouncements

In January 2003, the FASB issued FASB Interpretation No. 46 (FIN 46 ), Consolidation of Variable Interest Entities. FIN 46 clarifies the application of Accoun ting Research Bulle ti n No . 51, Consolidated Financial Statements , to certain entities in which equity investors do not have the characteris tics of a controlling financial interest or do not have sufficient equity at risk for the entity to finance its activities without additional subordinated financial support from other parties . FIN 46 applies immediately to variable interest entities created after January 31 , 2003, and to variable interest entities in which rprise obtains an interest after that date . It applies in the fiat fiscal year or interim period beginning after June 15, 2003, to variable interest entities i n Zench an enterprise holds a variable interest that it acquired before Febn 1, 2003 . FIN 46 applies to public enterprises as of the beginning of the applicable interim or annual period. On October 8, 2003, the FASB decide to defer FIN 46 until the first reporting period ending after December 15, 2003 . The provisions of this Interpretation did not have a material impact on the Company a financial condition or results of operations.

In December 2003, the FASB issued FIN No. 46R, Consolidation of Variable Interest Entities, clarifying the application of Accounting Research Bulle tin No. 51, Consolidated Financial Statements, to certain entities in which equity investors do not have the characteristics of a controlling financial interest or do not have sufficient equity at risk for the entity to finance its activities without addi tional subordinated financial support. The p rovisions of this Interpretati on do not have a material impact on the Company s financial condi tion or results of operations.

In December 2003 ,the FASB revised SFAS 132, Employers Disclosure About Pensions and Other Post Retirement Bene fits. This Statement does not change the measurement or recognition of those plans required by FASB 87, Employers Accounting for Pensions , and No . 106, Employers Accounting for Post Retirement Benefits Other than Pensions . This Statement retains the disclosure requirements contained in FASB No . 132, Employers Disclosure about Pensions and Other Post Retirement Plans. The p rovisions of this Statement do not have a material impact on the Company s financial condi ti on or results of operations. During the six months ended June 30 ,2004 and 2003, the emp loyer 401-K match was $218,000 and $150,000, respectively .

In February 2004 ,the FASB issued revised FASB Staff Positions (FSP ) pertaining to FIN 46(R). The revised FSPs replace certain previously issued FIN 46 FSP for entities to which FIN 46(R) is applicable . This revision to FIN 46 did not have a material impact on the Company s financial condi tion or results of operation.

In February 2004 , the FASB revised SFAS 133, Accounting for De rivative Instruments and Hedging Activities for Implementation issue E2L, AIJ, and C6 . The revisions to SFAS 133 did not have a mate rial impact on the Company s financial condition or results of operation .

In June 2004, the FASB discussed EITF 04 -08, The Effect of Contingently Convertible Debt on Diluted Ea rnings Per Share . The EITF task force has proposed that companies count the shares that could be issued upon convers ion of securities like the Company s debentures when calcula ting fully diluted per share earnings. This EITF is not yet effective. However, we disclosed in Note 2 the potential effect of this EITF on the Company s fully diluted EPS calcula tion.

Note 9. Commitments and Contingencies

Patent Litigation

Th ere has been substantial litigation in the pharmaceutical , biological, and biotechnology industries with respect to the manufacture , use, and sale of new products that are the subject of con flicting patent rights. One or more patents cover most of the brand name cont rolled-release products for which we are developing gene ric versions . Under the Hatch-Waxman Amendments, when a drug developer files an ANDA for a generic drug, and the developer believes that an unexpired patent which has been listed with the FDA as covering that brand nanx product will not be infr inged by the developer a product or is invalid or unenforceable , the developer must so certify to the FDA . Th at certification must also be provided to the patent holder, who may challenge. the developers certification of non-infringement , invalidity or unenfarceabilty by filing a suit for patent infrin(pement within 45 days of the patent holer s receipt of such certification. If the patent holder files suit, the FDA can review and approve the ANDA, but is prevented from granting final marketing approval of the product until a final judgment in the action has been rendered , or 30 months from the date the certification was received, whichever is sooner. Should a patent holder commence a lawsuit with respect to an alleged patent in fringement by us, the uncertainties inherent in test tilitigation make the outcome of such litigation difficult to predict. The delay in obtaining FDA approval to market our product candidates as a result of litiga on, as well u the expense of such litigation, whether or not we are successflil, could have a material adverse effect on our results of opera tions and financial position. In addition, there can be no assurance that any patent li ti gation will be resolved prior to the 30-month period. As a result, even if the FDA were to approve a product upon expiration of the 30-month period, we may not commence marketing that product if patent litigation is still pending .

10 Back to Contents

Lawsuits have been filed against us in connec tion with fourteen of our Paragraph IV filings. The outcome of such litigation is difficult to p redict because of the uncertainties inherent in patent litigation.

As part of our patent litigation strategy, we obtained two policies covering up to $7 million of patent infringement liability insurance from American international Special ty Line Company (AISLIC ), an affiliate of AIG intemationa1. This li tigation insurance covered us against the costs associated with patent infringement claims made agamat ua relating to seven of the ANDAa we filed under Paragraph IV of the Hatch-Waxman Amendments . Both policies have reached their limit of liability. While Teva has agreed to pay 45% to 50% of the atto rneys fees and costs (in excess of the $7 million covered by our insurance policies) related to the twelve products covered by out strafe g~c alliance agreement with Teva , we will be responsible for the remaining expenses and cosh for these products , and all of the costs associated with patent litigation for our other products and our future products.

We do not believe that this type of li tigation insurance will be available on acceptable terms for our current or future ANDAs. In those cases, our policy is to record such expenses as incurred.

Although the outcome and costs of the asserted and unasse rted claims is difficult to predict because of the uncertainties inherent in patent li tigation, management does not expect the Company s ul ti mate liability for such matters to have a material adverse effect on its financial condition, results of opera tions, or cash flows .

FIN 45 in November 2002, the FASB issued FIN No . 45, Guarantors Accoun ting and Disclosure Requirements for Guarantees , Including Indirect Guarantees of Indebtedness of Others. Guarantees and claims arise during the ordina rycourse of business from relationships with suppliers, customers, and strategic partners when the Company undertakes an obligation to guarantee the performance of other through the delivery of cash or other assets if specified triggering events occur. Non-performance under a contract by the guaranteed party trigger the obligation of the Company . As of June 30, 2004, all indemnifications included in agreements as of that date are excluded from the scope of FIN No . 45 as they relate primarily to our own future performance and do not require any contingent payments .

As of June 30, 2004 , our total contractual commitments on loam, operating leases , and royalty agreements have not mate rially changed since December 31, 2003, as disclosed in our Report Form 10-K .

Note 10 . Loan Agreements with PIDA and DRP A

In April 2004 , the Company terminated the loan agreements with Pennsylvania Industrial Development Authority (PIDA) and Delaware River Pon Authority (DRPA ) and repaid the remaining balances totaling app roximately $992,000 .

Note 11. Loan and Security Agreement with Wachovia Bank N .A.

In June 2004 , the $25 million Loan and Security Agreement with Wachovia Bank N .A. was amended, as follows :

• The cash collateral requirement of $10,000,000 was removed. • The Adjusted Excess Availability Covenant was removed. • IMPAX will maintain at Wachovia Bank cash and investments in an amount not less than $25,000,000 . • If the amount of cash and investments decline below $25,000,000, then the Cash Collateral requirement of S 10 ,000,000 and Adjusted Excess AvailabilityCovenant will be re-establishe d • If the Company reports negative free cash flow in any quarter , then reserves in the amount of the negative free cash flow will be reported on the Borrowing Base. • The maximum aggregate Capital Expenditures during any fiscal year in the amount of $8 ,000,000 was amended to permit a maximum cumulative aggregated amount of $45,000,000 for fiscal years 2004 and 2005 . Note 12. Income Taxes

For the six months ended June 30, 2004 , the Company provided for income taxes of $506,000 or 5% of income before taxes , as compared to $0 for the 2003 period. The effective tax rate in 2004 reflects the partial reversal of the deferred income tax asset valua tion allowance recognized. The valuation allowance was reduced to reflect the utilization of federal and state loss carryforwards that offset the current tax component of the income tax provision. We evaluate the realizability of deferred tax assets on an annual and quarterly basis or if there is a significant change in circumstance that may cause a change in our judgment about the realizability of our deferred tax assets. Any valuation allowance that may be released as a result of the evaluation process could have a material effect on our future results of operations . At December 31, 2003 , the Company had a net operating loss-carryforward totaling approximately $94,600,000, which expires from 2009 through 2023.

Note 13. Subsequent Events

On July 12, 2004 , the Company announced that it has signed a series of agreements with Leiner Health Products , LLC for the supply and distribution of the Company's Loratadine Orally Disintegrating Tablets (ODT) and Loratsdine and Pseudoephedrine Sulfate Extended Release Tablets 24 hour p roducts. Both of these products are indicated for the relief of symptoms of seasonal allergic rhinitis (bay fever). These products will be manufactured by IMPAX and marketed by Leiner as over the counter (OTC) store brand equivalents to both Claritin® Reditabs® and Clari tin-D® 24-hour respective y. ITEM 2.

General

Impax Laborato ries, Inc. was formed through a business combination on December 14, 1999 between Impax Pharmaceuticals, Inc., a privately held drug delivery company, and Global Pharmaceutical Corporation, a generic pharmaceutical company . Impax Pharmaceuticals, Inc. merged with and into Global, with Impax stockholders receiving 3.3358 shares of Global common stock for each share of Impax Pharmaceu ticals , Inc. At the conclusion of the merger, Impax Pharmaceuticals, Inc. stockholders held over 70%of the combined company. For accounting purposes, the merger has been treated as a recapitalization of Impax Pharmaceuticals, Inc. with Impax Pharmaceuticals , Inc. deemed the acquirer of Global in a reverse acquisition. As a reverse acquisi tion, our historical operating results prior to the merger are those of Impax Pharmaceuticals, Inc. and only include the operating results of Global after the merger. In connec ti on with the merger, the surviving company changed its name to Impax Laboratories, Inc .

We are a technology based, specialty pharmaceutical company applying formulation and development expertise, as well as our drug delive ry technology, to the development of controlled-release and niche generics , i n addition to the development of branded p roducts . As of June 30, 2004 , the Company is marketing thirty-three generic pharmaceuticals , which represent dosage variations of fourteen different pharmaceutical compounds, and has fou rteen applications under review with the Food and Drug Administration (FDA), including five tentatively approved, addressing approximately $5 .2 billion in U .S . prod es in the twelve months ended April 30, 2004rs , according to NDCHealth. Eleven of these pending filings were filed under Paragraph IV of the Hatch-Waxman Amendments . The Company has approximately twenty-four other products in various stages of development for which applications have not yet been filed . These other products are generic ve ions of pharmaceutical products that had U.S. sales of approximately $14.6 billion in the twelve months ended April 30, 2004, according to NDCHealth

Critical Accounting Policies

The Company recognizes revenue in accordance with SEC Staff Accounting Bulletin ( SAB) 101 issued by the SEC in December 1999. We recognize revenue from the sale of products when the shipment of products is received and accepted by the customer. Provisions for estimated discounts, rebates, chargebacks, returns and other adjustments are provided for in the period the related sales are recorded . In December 2003, the SAB 104 was issued by the SEC. This bulletin clarifies portions of Topic 13 of the Staff Accounting Bulletin to be consistent with current accounting and auditing guidance and SEC rules and regulations and revises accounting guidance contained in SAB 101 related to multiple element revenue arrangements of Emerging Issues Task Force (EITF) No. 00-21 superseded as a result of the issuance .

Emerging Issues Task Force (EITF) No. 00-21 supplemented SAB 101 for accounting for multiple element arrangements. The Company has entered into several strategic alliances that involve the delivery ofmultiple Products and se rvices over an extended pe riod of time . In multiple element arrangements, the Company must determine whether any or all of the elements of the arrangement can be separated from one another. If separation is possible, revenue is recognized for each deliverable when the revenue recognition criteria for the speci fic deliverable is achieved. If separation is not possible, revenue recogni tion is required to be spread over an extended period.

Under EITF No . 00-21, in an arrangement with multiple elements, the delivered item should be considered a separate unit of accounting if all of the following criteria are met:

1) the delivered item has value to the customer on a standalone basis; 2) there is objective and reliable evidence of the fair value of the undelivered item ; and 3) if the arrangement included a general right of retu rn, or whether delivery or performance of the undelivered item is considered p robable. The Company reviews all of the terms of its strategic alliances and follows the guidance from SAB 104 AND EITF No. 00-21 for multiple element arrangements. Up front and mi lestone payments from these strategic allianc es are deferred and recognized over the life of the agreements as the Company fulfills its contractual obligation to manufacture and supplies products during this period. In addition , in some agreements, the Company receives and records royalty revenue based on a percentage of the strategic partners total sales to their customers of the p roducts supplied by IMPAX .

In June 2001 , the Company entered into a Strategic Alliance Aunt with a subsidia ryof Teva for twelve controlled-release generic pharmaceutical products. The agreement granted Teva exclusive U.S. prescription marketing rights for these products for a period of ten years from the date of Teva s first sale of the products .

Returns Reserv e

The Company estimates future product returns at the time of ask. Product returns by wholesalers principally relate to the return of expired products . For product return rese rves, we consider volume and mix of p roduct in the marketplace, historical return rates, and the competitive environment, all of which require us to use estimates and assumptions . IMPAX introduces a number of new products each year. As a result , the Company has been able to monitor historical return rates for new products. Based on our histo rical data, since we are in one business segment, we have found that generic pharmaceu ti cal product returns are alike and that new product returns have similar characteristics to existing products . Usually , new products are AB rated (products that demonstrated bioequivalence with innovator products), have 24 month expiration dating, and are marketed to the same customers, i .e., wholesalers, warehousing chains, distributors , etc . The AB rated products are substitutable by the pharmacist for the innovator products . The non-AB rated products, such as the LIPRAM product family, generally, may not be substituted by the pharmacist as they are therapeutic alternatives, not generic substitutes . Any change to a pati ent 's prescription to an alternati ve product requires the patient a physician approval for the substitution. We are monitoring returns by product and, where applicable , we establish specific product retu rn reserves and/or adjust our estimates of the future return rates based on va rious business and compe titive assumptions.

Th e sales return rese rve is calculated using an historical lag nod that is, the time between when the product is sold and when it is ultimately returned as determined from the Company a system generated lag pen od report and return rates, adjusted by estimates of the future return rates based on various assumptions which may include changes to internal policies and procedures,changes in business practices and commercial terms with customers, competitive position of each product, amount of inventory in the pipeline, the introduction of new products , and changes in market sales informati on .

13 Back to Contents

Our returned goods policy requires prior authorization for the return , with corresponding credits being issued at the original invoice prices, less amounts previously gtyranted to the customer for rebates and chargebacka . Products eligible for return must be expired and returned within one year following the expiration date of the product. Prior to 2002, we required returns of products within six months of expiration date. Because of the lengths of the lag period and volatili that may occur from quarter to quarter,we arc currently using a rolling 22-month calculation to estimate our product return rate .

The Company believes that its es timated returns reserves were adequate at each balance sheet data since they were formed based on the informa tion that was known and available,which were supported by the Company s historical experience when similar events occurred in the past , and management s overall knowledge of and experience in the generic pharmaceutical industry. In estimating its returns rese rve, the Company looks to returns after the balance sheet date , but prior to filing its financial statements to ensure that any unusual trends are considered .

Generally, sales rebates are calculated at the point ofWe, based on pre-existing written customer agreements by product and accrued on a monthly basis. However, we do estimate additional rebates for specific purposes, i .e., new pharmacy store openings.

The vast majority of chargebacks are also calculated at the point of sale as the difference between list price and contract price by product (with the wholesalers) and accrued on a monthly basis . There are additional chargebacks that are estimated at the point of sale to the wholesaler as the difference between the wholesalers contract price and the Company s contract price with retail pharmacies and buying groups .

The Company believes it is important for the users of its financial statements to understand the key components, which reduce gross sales to net sales .

Inventor y

Our inventories are valued at the lower of cost or market. Costs are determined using a standard cost method, first-in, first-out (FIFO) flow of goods . Costs include materials, labor, quality control and production overhead . We review and adjust inventory for short-dated product and inventory commitments under supply agreements based on projections of future sales and market conditions . The Company, as do most companies in the generic pharmaceutical industry, may build inventories of certain ANDA-related products that have not yet received FDA approval and/or satisfactory resolution of patent infringement litigation, when it believes that such action is appropriate to increase its commercial opportunity . If our inventory is greater than estimated shipments to our customers, there may be an inventory write-down . Therefore, the Company s management must make significant estimates relating to inventory .

Imnaired Assets

The Company evaluates the carrying value of long-lived assets to be held and used, including definite lived intangible assets, on an annual basis, when events or changes in circumstances indicate that the carrying value may not be recoverable. The carrying value of a long-lived asset is considered impaired when the total projected undiacounted cub flows from such asset is separately identifiable and is less than its carrying value . In that event, a loss is recognized based on the amount by which the carrying value exceeds the fair value of the long-lived asset . Fair value is determined primarily using the projected cash flows discounted at a rate commensurate with the risk involved . Losses on long-lived assets to be disposed of are determined in a similar manner . As the Company s assumptions related to assets to be held and used are subject to change, additional write-downs maybe required in the future .

Goodwill

Prior to the adoption of Statement of Financial Accounting Standards (SFAS ) No. 142, Goodwill and Other Intangible Assets, we amortized goodwil l on a straight-line basis over its estimated useful life . The Company adopted the provisions of SFAS No. 142, effective January 1, 2002; no impairment was noted. Under the provisions of SFAS No . 142, the Company performs the annual review for impairment at the reporting unit level, which the Company has determined to be consistent with its business segment, that is, the entire Company .

Effective January 1, 2002, we evaluated the recoverability and measured the possible impairment of our goodwill under SFAS 142 . The impairment test is a two-step process that begins with the estimation of the fair value of the reporting unit . The first stop screens for potential impairment and the second step measures the amount of the impairment, if any. Our estimate of fair value considers publicly available information regarding the market capitalization of our Company, as well as (i) publicly available information regarding comparable publicly-traded companies in the generic pharmaceutical industry, (ii) the financial projections and future prospects of our business, including its growth opportunities and likely operational improvements, and (iii) comparable sales prices, if available.

14 Back to Contents

As part of the first step to assess potential impairment, we compare our estimate of fair value for the Company to the book value of our consolidated net assets. If the book value of our net assets is greater than our estimate of fair value, we would then proceed to the second step to measure the impairment, if any.

The second step compares the implied fair value of goodwill with its carrying value . The implied fair value is determined by allocating the fair value of the reporting unit to all of the assets and liabilities of that unit as if the reporting unit had been acquired in a business combination, and the fair value of the reporting unit was the purchase price paid to acquire the reporting unit. The excess of the fair value of the reporting unit over the amounts assigned to its assets and liabilities is the implied fair value of goodwill . If the carrying amount of the reporting unit goodwill is greater than its implied fair value, an impairment loss will be recognized in the amount of the excess.

On a quarterly basis, we perform a review of our business to determine if events or changes in circumstances have occurred which could have a material adverse effect on the fair value of the Company and its goodwill . If such events or changes in circumstances were deemed to have occurred, we would consult with one or more valuation specialists in estimating the impact on our estimate of fair value . We believe the estimation methods are reasonable and reflective of common valuation practices. We perform our annual goodwill impairment test in the fourth quarter of each year.

Results of Operations

Except for the six months ended June 30, 2004, we have incurred net losses in each quarter since our inception. We had an accumulated deficit of $94,929,000 at June 30, 2004.

Three Months Ended June 30, 2004, Compared to Three Months Ended June 30, 2003

Overview

The net income for the three months ended June 30, 2004, was $572 ,000 as compared to a net loss of $2,284,000 for the three months ended June 30, 2003

Revenue s

Revenues for the second quarter of 2004 were $30,845,000, up more than 119% compared with revenues of 514,067,000 h the prior years second quarter . The year-over-year increase for the quarter was primarily due to shipments of our generic versions of Wellbutrin® SR (Bupropion Hydrochloride) 100 mg and 150 mg Controlled Release Tablets, and Dec of mycin® (Demeclocycline Hydrochloride) ISO mg and 300 mg Tablets, which commenced during the first quarter of 2004; Zyban® (Bupropion Hydrochloride) and Sinemet® CR (Carbidope/Levodope) Extended Release Tablets, which commenced during the second quarter of 2004 ; and higher over-the-counter (OTC) product revenues . The sequential quarter decline was due to timing of product shipments and pipeline filling, particularly as related to the launch of Bupropion Hydrochloride in the fiat quarter. During the 2004 second quarter, IMPAX s revenues from sales of Bupropion Hydrochloride products, through our strategic alliance agreements with Teva and Andrx, were approximately $8,089,000, compared with $23,870,000 in the first quarter.

Total Revenues 30,304 S 13,460

The quarter-to-qua rter increase of app roximately $6.9 million in Global products were primarily due to new products introduced in 2004 and late 2003, such as Demeclocycline of approximately $3 .6 million, Carbidop"evodopa of approximately $0 .8 mil lion, and Flavoxate of approximately $0 .9 million, as well as higher LIPRAM products of approximately $1 .2 million .

IMPAX has selectively waived its rights to this exclusivity to Teva Pharmaceuticals USA Inc. and will be sharing in the profits of Teva's Metfonnin HCI Extended Release Tablets as provided for in the Strategic Alliance A greement between IMPAX and Teva signed in June 2001 .On August 2, 2004 , the FDA granted final marketing. approval to the Company a ANDA for its generic version of Glucophage XR, Metformin HCI Extended Release Tablets, 500 mg . Bristol-Myers Squibb markets Glucophage XR for the improvement of glycemic control in patients with type 2 diabetes . According to NDCHealth, U.S. market sales of Glucophage XR 500 mg and other marketed generic versions were approximately $376 million in the twelve months ended June 30, 2004 .

ITEM 3 . QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RIS K The Company s cash and cash equivalents includes U .S. government and short-term high-grade commercial paper stated at cost which approximates market value. The pri mary objec ti ve of the Company s investment activities is to preserve principal and maximi zeyields without significantly increasing risk. To achieve this objec tive, the Company maintains its portfolio in a variety of h~h credit quality securities, including U.S. Government securities, treasu ry bills, and short-term high-grade commercial paper. One hundred percent of the Company s portfolio matures in less than one year . The carrying value of the portfolio approxima tes the market value at June 30 ,2004.The Company s debt instruments at June 30, 2004, are subject to fixed and variable interest rates and principal payments. We believe that the fair value of our fixed and variable rate long-term debt approximates their carrying value of approximately $108 million at June 30, 2004 . While changes in market interest rates may affect the fair value of our fix ed and variable rate long-term debt, we believe the effect, if any, of reasonably possible near-term changes in the fair value of such debt on the Company s financial statements will not be material.

We have no interest rate or derivative financial instruments nor material foreign exchange risks . We are also not party to any off-balance-sheet arrangements , other than operating leases.

ITEM 4. CONTROLS AND PROCEDURES The Company, under the supervision and with the participation of our management, including our principal executive officer and our principal financial officer, evaluated the effectiveness of our disclosure controls and procedures (u defined in Exchange Act Rule 13a- 15[e)), as of the end of the period covered by this report . Based on this evaluation, our principal executiveofficer and our principal financial officer concluded that our disclosure cont rols and procedures are effective in reaching a reasonable level of assurance that information required to be disclosed by us in the reports that we file or submit under the Securities Exchange Act of 1934, as amended, is recorded,processed, summarized, and reported within the time period specified in the Securities and Exchange Commission s rules and forms. The p rincipal executive officer and principal financial officer also conducted an evaluation of inte rnal control over financial reporting ( Internal Control) to determine whether any changes in Internal Controls occurred during the quarter that have materiall y affected, or which are reasonably likely to materially affect , Inte rnal Cont rols.

Based on this evaluation, there has been no such change during the quarter covered by this report. A control system, no matter how well conceived and operated , can provide only reasonable , not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resou rce constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems,no evaluation of cont rols can provide absolute assurance that all cont rol issues and instances of fraud, if any, within the Company have been detected. The Company conducts periodic evaluations of its internal cont rols to enhance, where necessary, its procedures and controls . Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected.

PART 11- OTHER INFORMATION

ITEM 1 . LEGAL PROCEEDING S

Patent Litigatio n

There has been substantial li tigation in the pharmaceutical , biological, and biotechnology industries with respect to the manufacture, use, and sale of new products that are the subject of conflic ting patent rights. One or more patents cover most of the brand name controlled-release products for which we are developing gene ric versions . Under the Hatch-Waxman Amendments, when a drug developer files an ANDA for a generic drug, and the developer believes that an unexpired patent which has been listed with the FDA as covering that brand rtame product will not be infringed by the developers product or is invalid or unenforceable, the developer must so certify to the FDA. That certification must also be provided to the patent holder, who may challenge the developers certification of non -infringement, invalidity or uncnforceabilty by filing a suit for patent infrin?ement within 45 days of the patent holder s receipt of such cer tification. If the patent holder files suit, the FDA can review and approve the ANDA, but is prevented from granting final marketing approval of the product until a final judgment in the action has been rendered , or 30 months from the date the certifica tion was received, whichever is sooner. Should a patent holder commence a lawsuit with respect to an alleged patent infringement by us, the uncertainties inherent in patent litigation make the outcome of such litigation difficult to predict. The delay in obtaining FDA app roval to market our product candidates as a result of litigation, as well as the expense of such litigation, whether or not we are successful , could have a material adverse effect on our results of opera tions and financial position. In addition, there can be no assurance that any patent litigation will be resolved p rior to the 30-month pe riod. As a result, even if the FDA were to approve a product upon expiration of the 30-month period, we may not commence marketing that product if patent litigation is s till pending .

Lawsuits have been filed against us in connection with fourteen of our Paragraph IV filings. The outcome of such litigation is difficult to predict because of the uncertainties inherent in patent litigation.

;The Omeprazole Cas a

In May 2000, AstraZeneca AB and four of its related companies filed suit against IMPAX in the U.S. District Courtin Wilmington, Delaware claiming that IMPAX s submission of an ANDA for Omeprazole Delayed Release Capsules, 10 mg and 20 mg, cons titutes infringement of six U.S. patents relating to AstraZeneca s Prilosec product. The action seeks an order enjoining IMPAX from marketing Omeprazole Delayed Release Capsules, 10 as and 20 mg until February 4, 2014 , and reimbursement for costs and atto rney fees associated with this litigation .

In February 2001, AstraZeneca and the same related companies filed the same suit against IMPAX in the same federal court in Delaware for infringement, based upon IMPAX s amendment to its ANDA adding 40 mg strength Omeprazole Delayed Release Capsules .

AstraZeneca filed essentially the same lawsuits against nine other generic pharmaceutical companies (Andrx, Genpharm, Cheminor, Kremers, LEK, Eon, Mylan, Apotex, and Zenith). Due to the number of these cases, a multidistrict litigation proceeding, In re Omeprazole 10 mg, 20 mg, and 40 mg Delayed Released Capsules Patent Litigation, MDL-1291, has been established to coordinate pre- trial proceedings. Both lawsuits filed by AstraZeneca against IMPAX have been transferred to the mul ti district litigation.

Early in the multidistrict litigation, the trial court ruled that one of the six patents-in-suit was not infringed by the sale of a gene ric omeprazole product and that certain other patents were invalid. These rulings effectively eliminated four patents from the trial of these infringement can, although AstraZeneca may appeal these rulings as part of the overall appeal process in the case .

On October 11, 2002 , after a t rial involving Andrx, Genpharm Cheminor, and Kretners, the t rial judge handling the multidistrict litiga ti on ruled on AstraZeneca s complaints that three of these four defendants (First Wave Defendants ) infringed the remaining patents-in-suit. The trial judge ruled that three of the First Wave defendants, Andrx, Genpharm, and Cheminor , infringed the rcmaininp two patents asserted by AstraZeneca in its complaints, and that those patents are valid un til 2007 . In the same ruling, the trial court ruled that the rem aining First Wave Defendant , Kremers , did not infringe either of the remaining two patents . This defendants formula tion differed from the formula tion used by the other First Wave Defendants in several respects. In mid-December 2003 , the U .S. Court of Appeals for the Federal Circuit affirmed the October 2002 ruling in all respects . Subsequent petitions for rehearing have been denied.

The formulation that IMPAX would employ in manufacturing its generic equivalent of omeprazole has not been publicly announced. IMPAX s formulation has elements that resemble those of other First Wave Defendants, but it also has elements that differ. Although the ruling by the trial court in the multidistrict litigation has a significant effect on the course of AstraZeneca s litigation against IMPAX, application of the trial courts opinion is no t certain. IMPAX believes that it has defenses to AstraZeneca s claims of infringement, but the opinion rendered by the trial court in the First Wave cases makes the outcome of AstraZeneca s litigation against IMPAX uncertain .

Two of the remaining six defendants (Second Wave Defendants) filed Motions for Summary Judgment of Non-Infringement, based upon the October 2002 ruling. The trial court has deferred ruling on those motions until discovery is complete d

In December 2003, the trial court entered a new scheduling order governing pre-trial proceedings relating to the Second Wave Defendants, including IMPAX. The schedule for comple tion of the litigation in the Second Wave , including AstraZeneca's litigation against IMPAX, now provides that all fact discovery (with certain ex ceptions) is complete. AstraZeneca's expert reports on issues as to which it bears the burden of proof, including issues of alleged infringement, were produced on February 17, 2004. IMPAX's responsive expert reports were produced on July 12, 2004.

Under the December 2003 scheduling order, Astra's reply reports would have been due on August 6, 2004 , and expert depositions would have commenced shortly thereafter. Following receipt of IMPAX's six expert reports on July 12, 2004 , as well as 17 other reports produced by four other defendants, Astra requested a further modification of the scheduling order . Astra's request for a three-month extension of the time for its reply reports was denied, but the Court granted Astra an additional five-week period to respond to the defendants' rebuttal reports on non-infringement. The schedule for expert depositions must be re-established Nevertheless, expert depositions will be conducted between Se ptember 14, 2004 , when reply reports are now due , and the end of 2004. Given the delays which have thus far occu rred in the litigation and the number of experts already designated by the pa rties, it is uncertain whether the expe rt depositions can be completed in the time allotted by the present schedule.

Under the December 2003 schedule , Motions for Summary Judgment may not be filed, as of right, until October 19, 2004 . IMPAX has recently requested permission to file an earlier motion for summary judgment on one aspect of the case. Other defendants have also requested permission to file early motions for summaryjudgment on other aspects of the litigation .

IMPAX may file additional Motions for Summa ry Judgment, including other Motions for SummaryJudgment of Non-Infringement, following the close of all discovery or after October 19, 2004, whichever conies first. If the case is not resolved by summary judgment, the case involving IMPAX will be returned to the U .S . Dist rict Court in Delaware for trial. It is likely, given the proceedings in the First Wave cases , that the case against IMPAX will be transferred back to New York for a consolidated trial before the saute judge who decided the First Wave cases . IMPAX believes, however, that any trial that might be scheduled in the case will commence in the first half of 2005 .

If IMPAX does not file a Motion for Summa ry Judgment, or if such a Motion is denied,the cou rt will schedule a date for trial. IMPAX intends to vigorously defend the action brought by AstruZeneca.

In August 2003, the court issued an order dismissing four of the patents -in-suit, three with prejudice . On September 30, 2003, as a result of the court s dismissal, AstraZeneca served each of the Second Wave Defendants , including IMPAX, with an amended complaint. In October 2003, IMPAX filed an answer to the amended complaint in which we asserted a new counterclaim with antitrust allegations . The counterclaim will be severed, and proceedings relating to it will be stayed until after trial of the patent infringement case .

Aventis Pharmaceuticals Inc- at al. Y. i_MPAX: The Fexofenadine Casa

On March 25 , 2002 , Aventis Pharmaceuticals Inc., Merrell Pharmaceuticals Inc., and Carderm Capital L.P . (collectively referred to as Aventis) sued IMPAX in the U.S . District Court for the District of New Jersey (Civil Action No. 02-CV-1322)alleging that IMPAX s proposed fexofenadine and pseudoephedrine hydrochloride tablets , containing 60 mg of fexofenadine and 120 mg of peeudoephedrine hyd rochloride, infringe U .S . Patent Nos . 6,039,974 ; 6,037,353 ; 5,738,872 ; 6,187,791 ; 5,855 ,912; and 6.113,942. On November 7, 2002, Aventis filed an amended complaint,which added an allegation that IMPAX s Fexofenadine and Pseudoephedrirne Hydrochloride 60 mg1I20 mg Extended Release Tablet product in fringes U.S. Patent No . 6,399,632 . Aventis seeks an injunction preventing IMPAX from marketing its Fexofenadine and Pseudoephedrine Hydrochloride 60 mg/120 mg Extended Release Tablet product until the patents-in-suit have expired, and an award of damages for any commercial manufacture, use, or sale of IMPAX s Fexofenadine and Pseudoephednne Hydroch lori de 60 mg/I20 mg Extended Release Tablet product , together with costs and attorneys fees .

24 Back to Contents

Fact discovery in this action is scheduled to close on October 29, 2004 . IMPAX believes that it has defenses to the claims made by Aventis based on noninfringement and invalidity. A tentative trial date has been scheduled for October 2005.

Aventis has also filed a suit against Barr Laboratories, Inc., Mylan Pharmaceu ticals, Inc., Dr. Reddy a Pharmaceuticals and Teva Pharmaceu ticals USA, Inc. in New Jersey asse rting the same patent infringement against these defendants proposed Fexofenadine and Pseudoephedrine or Fexofenadine products. The IMPAX case has been consolidated for trial with the Barr, Mylan, Dr. Reddy and Teva cases .

On March 25 , 2004, Aventis and AMR filed a complaint and first amended complaint against IMPAX and Ranbaxy, alleging infringement of two additional patents relating to the process for making the ac tive pharmaceutical ingredient, fexofenadine hydrochlo ride. These patents, United States Patent Nos . 5,581,011 and 5 ,750,703, are owned by AMR and exclusively licensed to Aventis .

On July 23, 2003 , IMPAX filed Summary Judgment motions for non-infringement of U.S. Patent Nos . 6,039,974, 6,113,942, and 5,855,912 ; and for non-infringement and invalidity of U.S. Patent No. 5,738 ,872. Opposition, papers were filed on August 11, 2003 . Reply papers were filed on September 24, 2003 . On October 24, 2003 , IMPAX filed a brief discussing the impact of the recent Festo decision on their Motions for Summa ry Judgment of non-infringement. Oral argument for the Summary Judgment Motion regarding the 912, 942, and 974 patents was heard on November 3, 2003. Oral argument for the Summary Judgment Motion regarding the 872 patent was heard on December 8, 2003 . On June 29, 2004 ,the court granted the Company s Motions for Summary Judgment ofNon-infringer ent of the 912 and 942 paints and denied the Company s Motion for Summary Judgment of Non-infringement of the 974 patent. At the same tine, the court ordered that a ruling on the Company s motion for Summary Judgment for the Non-infringement of the 872 patent is reserved pending a Markman hearing to be held on September 9, 2004 to assist the court in construing the patents product-by-process claims .

Purdue Pharma L.P. at aL v IMPAX: The Oxycodone Cases

On Ap ril 11, 2002, Purdue Pharma and related companies filed a complaint in the U .S. District Court for the Southern District of New York alleging that IMPAX s submission of ANDA No. 76-318 for 80 mg OxyContin Tablets infringes three patents owned by Purdue . The Purdue patents are U.S. Patent Nos . 5,508 ,042, 5,549,912 and 5 ,656,295; all directed to cont rolled release opioid formulations. On September 19, 2002, Purdue filed a second Infringement Complaint regarding IMPAX s 40 mg OxyContin generic product . On October 9, 2002, Purdue filed a third Infringement Complaint regarding IMPAX s 10 m* and 20 mg OxyContin generic products. IMPAX filed its answer and counterclaims in each an on October 3, 2003 . On November 25, 2003, Purdue submitted their reply to our counterclaims. Purdue is seeking, among other things, a court order preventing IMPAX from manufacturing , using or selling any drug product that infringes the subject Purdue patents .

Purdue previously sued Boehringer Ingelheim/Roxane, Endo and Teva on the same patents. One or more of these defendants may resolve the invalidi ty issues surrounding the Purdue patents prior to when IMPAX a case goes to trial. The Boehringer Ingelheim/Roxane suit is stayed . The Endo action was tried in June 2003 and post trial briefs have been filed In January 2004 , the judge in the Endo action ruled that the three patents in suit , the same patents that Purdue had asserted against IMPAX, are unenforceable because they were inequitably procured and enjoined their enforcement . Purdue has appealed that ruling to the Court of Appeals for the Federal Circuit.

: The RHuzole Case

In June 2002 , IMPAX filed suit against Aventia Pharmaceu ticals, Inc. in the U.S. District Court in Wilmington, Delaware, seeking a declaration that the filing of an ANDA to engage in a commercial manufacture and/or sale of Riluzole 50 mg Tablets for treatment of patients with amyot rophic lateral scleroses (ALS) does not infringe claims of Aventis U .S . PatentNo. 5,527,814 (814 patent) and a declaration that this patent is invalid .

In response to IMPAX s complaint, Aventis filed counterclaims for direct in fringement and inducement of infringement of the 814 patent In December 2002, the district court granted Aventis Motion for PreliminaryInjunction and enjoined IMPAX from infringing , contributory infringin , or inducing any other person to infringe Claims 1, 4 or 5 of the 814 patent by selling, offaing for sale, distributing, marketing or exporting from the United States any pharmaceu ti cal product or compound containing riluzole or salt thereof for the treatment of ALS .

25 Back to Contents

The trial was completed on October 30, 2003 , and post-trial briefing was completed in December 2003. IMPAX is pursuing its a ssertions that claims of the 814 patent are invalid in view of prior an and are unenforceable in view of inequitable conduct committed during the prosecution of the patent before the United States Patent and Trademark Office (USPTO) .

On January 30, 2004 , the courtdenied IMPAX s Motion for Summary Judgment on inequitable conduct and, on February 5, 2004,the court denied IMPAX s Motion for Summary Judgment on non -infringement of certain claims . The court has not issued its trial rulings and did not rule on the thrd pre-trial Motion for Summa ry Judgment based on invalidi ty of the patent-in-suit.

If IMPAX is not ultimately successful in provin g invalidity or unenforceability , there is a substantial likelihood that the court will enter a permanent injunction enjoining IMPAX from marketing Riluzole 50 mg Tablets for the treatment of ALS in the United States until the expiration of the 814 patent (June 18, 2013). If IMPAX is ultimately successful in proving either defense, the preliminary injunction would be set aside and IMPAX would be permitted to market its Riluzole 50 mg Tablet product for the treatment of ALS in the United States .

Abbott Laboratories v. IMP X : The Fenotlbrate Tablet Cases In January 2003, Abbott Laboratories and Fournier Indust rie et Sante and a re lated company filed suit against IMPAX in the U.S. District Court in Wilmington, Delaware claiming that IMPAX s submission of an ANDA for Fenofibrate Tablets , 160 mg, constitutes in fringement of two U .S . patents owned by Fournier and exclusively licensed to Abbott, relating to Abbott s Tricor tablet product .

In March 2003 , Abbott and Fournier filed a second action against IMPAX in the same court nuking the same claims against IMPAX s 54 mg Fenofibrate Tablets. These cases were consolidated in Ap ril 2003 .

In September 2003, Abbottand Fournier filed a third ac tion against IMPAX in the U .S . District Court in Wilmington, Delaware , claiming that IMPAX s submission of its ANDA for 54 mg and 160 m g Fenofibrate Tablets constitutes infringement of a third patent recently issued to Fournier and exclusively licensed to Abbott. This action was also consolidated with the previousltwo consolidatedy actions in December 2003 . In January 2004, Abbott and Fournier filed a fourth action relating to IMPAX s 54 tug and 160 mg Fenof ablets based upon a claim of infringement of a fourth patent. All four cases were consolidated in March 2004. Fact and expert discovery in the consolidated cases closes in November 2004 and the trial is currently act for June 2005 . IMPAX has responded to all four complaints by asserting that its p roposed generic Fenofibrate Tablet products do not infringe the patents-in-suit and by asserting that the patents-in-suit are invalid.

All four actions seek an injunction preventi ng IMPAX from marketing its Fenofibrate Tablet products un ti l the expirati on of the patents (January 9, 2018) and an award of damages for any commercial manufacture, use, or sale of IMPAX s Fenofibrate Tablet product , together with costs and attorney fees .

Solvay Pharmaceuticals v. IMPAX : The Creon Case

On April 1 1, 2003 , Solvay Pharmaceuticals , Inc., manufacturer of the Creon line pancreatic enzyme products, brought suit against IMPAX in the U .S. District Court for the District of Minnesota claiming that IMPAX has engaged in false adver tising, unfair competition, and unfair trade practices under federal and Minnesota law in connection with the Company s marketing and sale of its Lipram products . The suit seeks actual and consequen tial damages, including treb le damages, attorneys fees, injunctive relief and declaratoryjudgments that would prohibit the substitu tion of Lipram for presc ripti ons of Creon. On June 6, 2003, IMPAX fi led a Mo tion for Dismissal of Plaintiffs Complaint, which sought to dismiss each count of Solvay s complaint . On January 9, 2004, the U .S. District Court issued a ruling on IMPAX s Motion for Dismissal, dismissing two of the counts set forth in the Complain t. including the count which sought a declara tory judgment that Lipram may not lawfully be substituted for prescripttons of Croon . On January 26, 2004, IMPAX filed its Answer to the Complaint and Counterclaim alleging that Solvay wrongfully interfered with IMPAX s business relationships. On February 17, 2004 , Solvay filed its Reply to IMPAX s Counterclaim. On February 24, 2004, the Rule 16 Scheduling Conference was held and, on Februa ry 25, 2004 , the Court issued a Scheduling Order set ting the deadline for discovery on Janua ry 14, 2005, and a trial date for July 1, 2005. Fact discovery is currently ongoing it this case. IMPAX believes it has defenses to Solv ay a allegations and intends to pursue these defenses vigorously.

Aiza Corporation Y. IMPAX : The Ozvbutvnln Case

On September 4, 2003, Alza Corporation ( Alza) filed a lawsuit against IMPAX in the U.S. District Court for the Northern Dist rict of California alleging patent infringement of one patent related to IMPAX s filing of an ANDA for a generic version of Ditropan XL (Oxybutynin Chloride) Tablets, 5 mg, 10 tng, and 15 mg. Alza seeks an injunction, a declaration of infringement, attorney a fees and costs . On October 24, 2003, IMPAX filed its Answer to the Complaint, which included defenses to the infringement claim , and counterclaimed for patent non-infringement and invalidi ty. Discovery is on-going and trial is currently set for November 2005.

On October 24, 2003, IMPAX filed a lawsuit against Alza in the U .S . District Court for the Northern District of California seeking a declaratoryjudgment that four Ain patents relating to IMPAX s filing of an ANDA fora generic version of Dit ropan XL (Oxybutynin Chloride ) Tablets, 5 rttg,10 mg, and 15 mg are invalid and/or not in fringed by the commercial manufacture,use, offer for sale, sale, or importation of the IMPAX product . On November 17, 2003, Alza moved to dismiss the Company s complaint for lack of subject matter jurisdic tion based on Alts s argument that there is no case or cont roversy between the parties with respect to these four patents . On Ap ril 19, 2004 , the Court denied Alza s motion . On May 18 , 2004, the Court ordered the ent ry of a stipulation of dismissal based on a covenant not to sue issued by Alza to the Company with respect to the four Alza patents in the case .

Shire Laboratories Inc. v IMPAX : The Adderall Case

On December 29, 2003 , Shire Laboratories, Inc., a subsidia ry of Shire Pharmaceuticals Group, PLC, filed a lawsuit against IMPAX in the U.S. District Cou rt for the District of Delaware alleging patent in fringement on U .S . Patent Nos . 6,322,819 and 6,605,300 related to filing of an ANDA to market a generic version of Adderall 30 mg capsules.

A tentative court date has been scheduled for October It, 2005.

OTHER LITIGATION

State of California Y. IMPAX

On August 7, 2003, IMPAX received an Accusa tion from the Department of Justice, Bureau of Narcotic Enforcement, State of California ( BNE ) , alleging that IMPAX failed to maintain adequate controls to safeguard precu rsors from theft or loss regarding our pseudoephedrine product in Janua ry 2003 . IMPAX contested the allegations in the Accusation and entered into discussions with the State of California, Department of Justice, to bring resolution to this matter. IMPAX has implemented a number of remedial measures aimed at imp roving the security and accountability of precursor substances used by IMPAX and regulated by the California Department of Justice , Bureau of Narcotic Enforcement . In March 2004, followin g a theft of pseudoephedrine from IMPAX s facili ties, the BNE filed an Amended Accusation, again alleging that IMPAX failed to maintain adequate cont rols to safeguard precursors from theft or loss regarding our pseudoephedrine product. In May 2004, a Notice of Hearing was received from BNE, which set the hearing of this matter, should one be necessa ry, for October 18 and October 19, 2004 . IMPAX is continuing its discussions with the State of California, Department of Justice, and hopes to resolve this matter without the need for a formal hearing.

Other than the legal proceedings described above, we are not aware of any other mate rial pending or threatened legal ac tions, private or gove rnmental, against us. However, as we file additional applications with the FDA that contain Paragraph IV certifications and develop new products, it is likely we will become involved in additional li tigation related to those filings or products.

Insurance

As part of our patent litigation strategy, we had obtained two policies covering up to $7 million of patent infringement liabili ty insurance from American Interna tional Special ty Line Company (AISLIC ),an affiliate of AIG International. Th is litigation insurance covered us against the costs associated with patent infringement claims made against us re lating to seven of the ANDAs we filed under Paragraph IV of the Hatch-Waxman Amendments. Both policies had reached their limits of liability . Whi le Teva has a~ro~ to pay 45% to 50% of the attorneys fees and costs (in excess of the $7 million expected to be covered by our insurance policies for six products) related to the twelve products covered by our strategic alliance agreement with them, we will be responsible for the remaining expenses and costs for these products,and all of the costs associated with patent litigation for our other products and our future products .

We do not believe that this type of litigation insuran ce will be available to us on acceptable terms for our other current or future ANDAs . In those cases, our policy is to record such expenses as incurred .

Product liability claims by customers constitute a risk to all pharmaceutical manufacturers . We currently car ry $80 million of product liability insurance for our own manufactured products . This insurance may not be adequate tocover any product liability claims to which we may become subject.

ITEM 2. CHANGES IN SECURITIES, USE OF PROCEEDS AND ISSUER PURCHASES OF EQUITY SECURITIES

On May 17, 2004, we fi led an amendment to our Restated Certificate of Incorporation , as amended, with the Secretary of State of the State of Delaware, which amendment increased the number of our authorized shares of common stock f rom 75,000,000 to 90,000,000 . Ourboard will generally be able to issue additional shares of common stock without the approval of our stockholders . These future issuances will dilute the ownership interests of our stockholders .

27 1.250% Convertible Senior Subordinated Debentures

On Ap ril 5, 2004, the Company issued and sold $95.0 million in aggregate principal amount of its 1 .250% convertible senior subordinated debentures due 2024. The debentures were sold by the Company to Citi*roup Global Markets Inc., Wachovia Capital Markets, LLC and First Albany Capital Inc., as initial purchasers, in a private placement exempt from rc;istrati on under the Securities Act of 1933, as amended (the Securities Act ) . We have been advised by the initial purchasers that they have resold ,and/or intend in the future to resell , the debentures to qualified institutional buyers (as defined in Rule 144A promulgated under the Securities Act) in transactions exempt from the registration requirements of the Secu rities Act in reliance on Rule 144A.

The issuance and sale of the debentures resulted in net proceeds to the Company of approximately $91,388,000 . These proceeds are being used for general corporate purposes, including working capital requirements , manufacturing of our products and research and development .

The debentures bear interest at the rate of 1 .250% per year. Interest on the debentures is payable on April I and October 1 of each year, be*inning on October 1, 2004 . The debentures are convertible by holders into shares of our common stock at a conversion price of $28.08 per share (which is subject to adjustment upon certain events , but represented a 30% premium over our stock price at the time the debentures were issued) . The debentures are convertible by holders into shares of our common stock if (1) the p rice of our common stock reaches a specific threshold; (2) the trading price for the debentures falls below certain thresholds; (3) the debentures have been called for redemption; or (4) certain corporate transactions occur.

The debentures mat re on April 1, 2024 , unless earlier redeemed, repurchased or converted. Before April 5, 2007 , we may redeem some or all of the debentures if the price of our common stock reaches a specific threshold , at a redemp ti on price that includes an additional payment on the redeemed debentures equal to $230.77 per $1,000 principal amount of debentures, less the amount of any interest actually paid or accrued and unpaid on the debentures . On and after April 5, 2007, the Company may redeem some or all of the debentures at certain specified redemp tion prices.

The debentures are the Company s unsecured obligati ons and are subordinated in right of payment to all of the Company s existing and future senior indebtedness. On Ap ril 1 , 2009, April 1, 2014, and April 1, 2019, and under certain circumstances, holders of the debentures will have the right to require us to repurchase all or any pa rt of their debentures at a repurchase price equal to 100% of the principal amount of the debentures, plus accrued and unpaid interest and liquidated damages, if any, to, but excluding the repurchase date .

In connection with the offering of the debentures, we filed a Form S- 3 registration statement with the SEC in June 2004. The registration statement has not yet been declared effective by the SEC. If the registration statement on Form S-3 is not declared effective by the SEC by October 4, 2004, then the interest rate payable on the debentures will be subject to increase.

3 NOTES TO FINANCIAL STATEMENTS THRHB MONTHS ENDE D MARCH 31, 2004 AND MARCH 31, 200 3

NOTE 1 . The financial statements included herein have been prepared by the Company pursuant to the rules and regulations of the Securities and Exchange Commission . Certain information and disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America have been condensed or omitted pursuant to such rules and regulations ; however, the Company believes that the disclosures are adequate to make the information presented not misleading . These condensed financial statements should be read in conjunction with the financial statements and the notes thereto included in the Company's latest Annual Report on Form 10-K . The results of operations for the three months ended March 31, 2004 are not necessarily indicative of the results of operations expected for the year ending December 31, 2004 .

Impax Laboratories, Inc . ("IMPAX," "we,' *us," or "the Company") focuses on the development, manufacturing, and marketing of specialty pharmaceutical products utilizing its own formulation expertise and drug delivery technologies . As of March 31, 2004, the Company is marketing thirty-three generic pharmaceuticals, which represent dosage variations of fourteen different pharmaceutica l compounds, and has seventeen applications under review with the Food and Drug Administration (FDA), including five tentatively approved, addressing approximately $5 .4 billion in U .S . product sales in the twelve months ended February 29, 2004, according to NDCHealth . Thirteen of these pending filings were filed under Paragraph IV of the Hatch-Waxman Amendments . The Company has approximately twenty-seven other products in various stages of development for which applications have not yet been filed . These other products are generic versions of pharmaceutical products that had U .S . sales of approximately $14 .5 billion in the twelve months ended February 29, 2004, according to NDCHealth .

Except for the three months ended March 31, 2004, we have experienced operating losses and negative cash flow from operations and our future profitability continues to be uncertain . As of March 31, 2004, our accumulated deficit was $99,333,000 and we had outstanding indebtedness in an aggregate principal amount of $16,608,000 . To remain operational, we must, among other things :

obtain FDA approval for our products ; prevail in patent infringement litigation in which we are involved, successfully launch our new products ; and comply with the many complex governmental regulations that deal with virtually every aspect of our business activities .

We expect to incur significant operating expenses, particularly for research and development, for the foreseeable future in order to execute our business plan . We, therefore, anticipate that such operating expenses, as well as planned capital expenditures, will constitute a material use of our cash resources .

On April 5, 2004, the Company completed a convertible senior subordinated debenture offering of $95,000,000 for net proceeds of $91,675,000 . The proceeds of the debentures will be used for general corporate purposes, including working capital requirements, manufacturing of our products, and research an d development .

To date, the Company has funded its research and development and other operating activities through equity and debt financings and strategic alliances .

CRITICAL ACCOUNTING POLICY RELATED TO REVENUE RECOGNITION

The Company recognizes revenue in accordance with SEC Staff Accounting Bulletin ("SAB") 101 issued by the BBC in December 1999 . We recognize revenue from the sale of products when the shipment of products is received and accepted by the customer . Provisions for estimated discounts, rebates, chargebacks, returns and other adjustments are provided for in the period the related sales are recorded . In December 2003, the SAD 104 was issued by the BBC . This bulletin revises and clarifies portions of Topic 13 of the Staff Accounting Bulletin to be consistent with current accounting and auditing guidance and SEC rules and regulations .

Emerging Issues Task Force (BITE) No . 00-21 supplemented SAB 101 for accounting for multiple element arrangements . The Company has entered into several strategic alliances that involve the delivery of multiple products and services over an extended period of time . In multiple element arrangements, the Company must determine whether any or all of the elements of the arrangement can be separated from one another . If separation is possible, revenue is recognized for each deliverable when the revenue recognition criteria for the specific deliverable is achieved . If separation is not possible, revenue recognition is required to be spread over an extended period . Under BIT? No . 00 -21, in an arrangement with multiple elements , the delivered item should be considered a separate unit of accounting if all of the following criteria are met :

the delivered item has value to the customer on a standalone basis, there is objective and reliable evidence of the fair value of the undelivered item ; an d if the arrangement included a general right of return, or whether delivery or performance of the undelivered item is considered probable .

The Company reviews all of the terms of its strategic alliances and follows the guidance from SIT? No . 00-21 for multiple element arrangements .

In June 2001 , the Company entered into a Strategic Alliance Agreement with e subsidiary of Teve for twelve controlled - release generic pharmaceutical products . The agreement granted Teva exclusive U .S . prescription marketing rights for these products for a period of ten years from the date of Teva's first sale of the products . Under the terms of this agreement, Teva has sole and exclusive right to determine all terms and conditions of sale to its customers, including pricing discounts , allowances , price adjustments , returns and rebates .

Revenues from product sales for these products under our strategic alliance are recognized at the time title and risk of loss transfers to Teva ' s customers . During the three months ended March 31, 2004 , the Company commenced shipping its Bupropion Hydrochloride 100 mg and 150 mg Controlled Release Tablets . Teva ships the Bupropion products to its customers and reports the results on a monthly basis . Teva provides to IMPAX a financial report detailing its gross sales less applicable chargebacks , rebates and other credits to arrive at net sales, cost of sale s information and gross margins for the Bupropion products . The Company is endeavoring to take steps under the Strategic Alliance Agreement to ensure that all such adjustments granted by its strategic partner in the future are reported to the Company on a timely basis . These steps include , but are not limited to, regular discussions with Teva management regarding their monthly financial reports to IMPAX on our products marketed by Teve via monthly teleconferences and quarterly meetings . These discussions will cover all the areas of revenue recognition for these products , including but not limited to, sales credits , product returns and internal control s over Teva's financial reporting to IMPAX . Our procedures will include a review of applicable documentation for IMPAX revenue sharing . The Audit Committee of the Company's Board of Directors may take additional steps as deemed necessary . Under the terms of the contract , the Company has the option to perform an annual audit with our strategic partner . The information on the financial report is used by IMPAX to record its monthly revenue for the Bupropion 100 mg and 150 mg products . Effective with the three months ended March 31 , 2004 , we began estimating returns for prescription products marketed by our strategic partners, such as Teva , called ' Rx Partners ," based on our internal returns analysis and historical indust ry statistics . Additionally, the amount of revenue that IMPAX ea rns is based on a reimbursement of manufacturing costs plus a fixed gross margin percentage .

Under the July 2003 Exclusivity Transfer Agreement with Andrx and Teva pertaining to the Bupropion Hydrochloride products, Andrx is entitled to certain payments for the sales of the 150 mg s trength for a 190-day period from the product launch date . These payments are made directly by Teva to Andrx .

EARNINGS PER SHARE

Basic earnings per share is computed by dividing net income by the weighted average common shares outstanding . Diluted earnings per share is based on the treasury stock method and is computed by dividing net income by the weighted average number of common shares and weighted average dilutive potential common shares outstanding, assuming the exercise of all in-the-money stock options . A reconciliation of the numerators and denominators of basic and diluted earnings per share consisted of the following (in thousands, except per share amounts) :

Mr .Mn 1 8 .t/ 1 11 .111 Included in the computation of fully diluted earnings per share are outstanding stock options and warrants with an exercise price less than the average market price of the common shares for the period . As of March 31, 2004 there were no stock options or warrants excluded from the fully diluted earnings per share calculation because all options and warrants exercise price were less than the average market price of common shares .

STOCK- BASED EMPLOYEE COMPENSATION

The Company accounts for stock-based employee compensation arrangements in accordance with provisions of Accounting Principles Board (APB) Opinion No . 25, "Accounting for Stock Issued to Employees ." Compensation cost for stock options, if any, is measured as the excess of the quoted market price of the stock at the date of grant over the amount an employee must pay to acquire the stock . The Company has adopted the disclosure only provisions of SPAS No . 123, "Accounting for Stock- Based Compensation" and SFAS No . 145, "Accounting for Stock-Based Compensation - Transition and Disclosure - An Amendment to PASS Statement No . 123 . "

Had compensation cost for the Company's Plans been determined based on the fair value at the grant dates for the awards under a method prescribed by SFAS No . 123, the Company's income and income per share would have been decreased to the pro forma amounts indicated below (in thousands, except per share amounts) :

The Company calculated the fair value of each option grant on the date of the grant using Black-Scholes pricing method with the following assumptions : for the three months ended March 31, 2004 and 2003, the dividend yield was 0% and 0% ; the weighted average expected option term was five years ; risk-free interest rate was 3% and 2 .694 ; the stock volatility for the three months ended March 31, 3004 and 2003 was 79 .48% and 69t, respectively . The weighted average fair value of options for March 31, 2004 and 2003 was $14 .12 and $1 .96, respectively .

The Company reports both basic earnings per share, which is based on the weighted-average number of common shares outstanding, and diluted earnings per share, which is based on the weighted-average number of common shares outstanding and all dilutive potential common shares outstanding .

NOTE 2 . Convertible Senior Subordinated Debentures

On April 5, 2004, the Company issued and sold $95 .0 million in aggregate principal amount of its 1 .250% convertible senior subordinated debentures due 2024 . The debentures were sold by the Company to Citigroup Global Markets Inc ., Wachovia Capital Markets, LLC and First Albany Capital Inc ., as initial purchasers, in a private placement exempt from registration under the securities Act of 1933, as amended (the "Securities Act") . We have been advised by the initial purchasers that they have resold, and/or intend in the future to resell, the debentures to "qualified institutional buyers" (as defined in Rule 144A promulgated under the Securities Act) in transactions exempt from the registration requirements of the Securities Act in reliance on Rule 144A . The issuance and sale of the debentures resulted in not proceeds to the Company of approximately $91,675,000 . These proceeds are being used for general corporate purposes, including working capital requirements, manufacturing of our products and research and development .

The debentures bear interest at the rate of 1 .2506 per year . Interest on the debentures is payable on April 1 and October 1 of each year, beginning on October 1, 2004 . The debentures are convertible by holders into shares of our common stock at a conversion price of $26 .06 per share (which represented a 30% premium over our stock price at the time the debentures were issued) . The conversion price is subject to adjustment in certain events if, (1) the price of our common stock reaches a specific threshold ; (2) the trading price for the debentures falls below certain thresholds, (3) the debentures have been called for redemption, or (4) certain corporate transactions occur .

The debentures mature on April 1, 2024, unless earlier redeemed, repurchased or converted . before April 5, 2007, we way redeem move or all of the debentures if the price of our common stock reaches ■ specific threshold, at a redemption price that includes an additional payment on the redeemed debentures equal to $230 .77 per $1,000 principal amount of debentures, less the amount of any interest actually paid or accrued and unpaid on the debentures . On and after April S, 2007, the Company may redeem some or all of the debentures at certain specified redemption prices .

The debentures are the Company's unsecured obligations and are subordinated in right of payment to all of the Company's existing and future senior indebtedness . On April 1, 2009, April 1, 2014, and April 1, 2019, and under certain circumstances, holders of the debentures will have the right to require us to repurchase all or any part of their debentures at a repurchase price equal to 1001 of the principal amount of the debentures, plus accrued and unpaid interest and liquidated damages, if any, to, but excluding the repurchase date .

In connection with the offering of the debentures, we are required to file a shelf registration statement by July S . 2004 with the Securities and Exchange Commission covering resales of the debentures and of the common stock issuable upon conversion of the debentures .

In November 2003, the RITP reached a consensus on Issue No . 00-21, 'Revenue Arrangements with Multiple Deliverables ." RITP Issue No . 00-21 provides guidance on how to account for arrangements that involve the delivery or performance of multiple products, services, and/or rights to use assts . The provisions of IITF Issue No . 00-21 applies to revenue arrangements entered into in fiscal periods beginning after June 1S, 2003 . We implemented the provisions of RITP Issue No . 00-21 in revenue recognition of certain strategic agreements . The company reviews all of the terra of its strategic alliances and follows the guidance from this Issue for all multiple element arrangements .

In December 2002 . the Financial Accounting Standards Board (PASS) issued SPAS No . 144, "Accounting for Stock-Rased Compensation - Transition and Disclosure, amendment of PASS Statement No . 123 ." This statement provides additional transition guidance for those entities that elect to voluntarily adopt the provisions of SPAS No . 123, 'Accounting for Stock Based Compensation .' Furthermore, SFAS No . 146 mandates new disclosures in both interim and year-end financial statements within the Company's Significant Accounting Policies footnote . The Company has elected not to adopt the recognition provisions of SPAS No . 123, as amended by SPAS No . 146 . Rowwr, the Company has adopted the disclosure provisions and has included this information in Note 1 to the Company's financial statements .

In January 2003, the PASS issued PASS Interpretation No . 46 ("FIN 46"), "Consolidation of Variable Interest Entities ." FIN 46 clarifies the application of Accounting Research Bulletin No . 5 1, "Consolidated Financial Statements,' to certain entities in which equity Investors do not have the characteristics of a controlling financial interest or do not have sufficient equity at risk for the entity to finance its activities without additional subordinated financial support from other parties . FIN 46 applies immediately to variable interest entities created after January 31, 2003, and to variable interest entities in which an enterprise obtains an interest after that date . It applies in the first fiscal year or Interim period beginning after June 1 5 , 2003, to variable interest entities in which an enterprise holds a variable interest that it acquired before February 1, 2003 . FIN 46 applies to public enterprises as of the beginning of the applicable interim or annual period . On October I, 2003, the PASS decided to defer PIN 46 until the first reporting period ending after December 1 3 , 2003 . The provisions of this Interpretation did not have a material impact on the Company's financial condition or results of operations .

In December 2003, the PASS issued PIN No . 46R, Consolidation of Variable Interest Entities, clarifying the application of Accounting Research Bulletin No . 51, Consolidated Financial Statements, to certain entities in which equity investors do not have the characteristics of a controlling financial interest or do not have sufficient equity at risk for the entity to finance its activities without additional subordinated financial support . The provisions of this Interpretation do not have a material impact on the Company's financial condition or results of operations . In February 2004, the FASB issued revised FASB Staff Position ("FSP") pertaining to FIN 46(R) . The revised FSPs replace certain previously issued FIN 46 FSP for entities to which FIN 46(R) is applicable . This revision to FIN 46 did not have a material impact on the Company's financial condition or results of operation .

In February 2004, the PASS revised SPAS 133, Accounting for Derivative Instruments and Hedging Activities for Implementation issue E2L, A1J, and C6 . The revisions to SFAS 133 did not have a material impact on the Company's financial condition or results of operation .

In December 2003, the PASS revised SFAS 132, "Employers' Disclosure About Pensions and Other Post Retirement Benefits ." This Statement does not change the measurement or recognition of those plans required by FASB 87, "Employers' Accounting for Pensions," and No . 106, "Employers' Accounting for Post Retirement Benefits Other than Pensions ." This Statement retains the disclosure requirements contained in PASS No . 132, "Employers' Disclosure about Pensions and Other Post Retirement Plans ." The provisions of this Statement do not have a material impact on the Company's financial condition or results of operations . During the three months ended March 31, 2004 and 2003, the employer 401-K match was $24,352 and $21,347, respectively .

In January 2004, the FASB issued FASB Staff Position FAS 106-1 to provide temporary guidance concerning the Medicare Prescription Drug Improvement and Modernization Act of 2003 .

NOTE 9 . COMMITMENTS AND CONTINGENCIES

Patent Litigation

There has been substantial litigation in the pharmaceutical , biological, and biotechnology industries with respect to the manufacture , use, and s ale of new products that are the subject of conflicting patent rights . One or more patents cover most of the brand name controlled-release products for which we are developing generic versions . Under the Hatch - Waxman Amendments, when a dru g developer files an ANDA for a generic dru g, and the developer believes that an unexpired patent which has been listed with the FDA as covering that brand name product will not be infringed by the developer 's product or is invalid or unenforceable , the developer must so certify to the FDA . That certification must also be provided to the patent holder , who may challenge the developer's certification of non-infringement , invalidity or unenforceebility by filing a suit for patent infringement within 45 days of the patent holder's receipt of such certification . If the patent holder files suit , the FDA can review and approve the ANDA, but is prevented from granting final marketing approval of the product until a final judgment in the action has been rendered, or 30 months from the date the certification was received , whichever is sooner . Should a patent holder commence a lawsuit with respect to an alleged patent infringement by us, the uncertaintie s inherent in patent litigation make the outcome of such litigation difficult to predict . The delay in obtaining FDA approval to market our product candidates as a result of litigation, as well as the expense of such litigation , whether or not we are successful , could have a material adverse effect on our results of operations and financial position . In addition, there can be no assurance that any patent litigation will be resolved prior to the 30-month period . As a result , even if the PDA were to approve a product upon expiration of the 30-month period , we may not commence marketing that product if patent litigation is still pending .

Lawsuits have been filed against us in connection with fourteen of our Paragraph IV filings . The outcome of such litigation is difficult to predict because of the uncertainties inherent in patent litigation .

As part of our patent litigation strategy, we had obtained two policies covering up to $ 7 million of patent infringement liability insurance from American International Specialty Line Company (" AISLIC" ), an affiliate of Al0 International . This litigation insurance covered us against the costs associated with patent infringement claims made against us relating to seven of the ANDAs we filed under Paragraph IV of the Hatch - Waxman Amendments . Both policies have reached their limit of liability . while Teva has agreed to pay 45% to 50% of the attorneys ' fees and costs (in excess of the $7 million covered by our insurance policies ) related to the twelve products covered by our strategic alliance agreement with Teva , we will be responsible for the remaining expenses and costs for these products , and all of the costs associated with patent litigation for our other products and our future products .

We do not believe that this type of litigation insurance will be available on acceptable terms for our current or future ANDAS . In those cases, our policy in to record such expenses as incurred .

Although the outcome and costs of the asserted and unasserted claims is difficult to predict because of the uncertainties inherent in patent litigation, management does not expect the Company ' s ultimate liability for such matters to have a material adverse effect on its financial condition , results of operations, or cash flows .

10 FIN 4 5

In November 2002, the FASB issued FIN No . 45, "Guarantor's Accounting and Disclosure Requirements for Guarantees, Including Indirect Guarantees of Indebtedness of Others ." Guarantees and claims arise during the ordinary cours e of business from relationships with suppliers, customers, and strategic partners when the Company undertakes an obligation to guarantee the performance of others through the delivery of cash or other assets if specified triggering events occur . Non-performance under a contract by the guaranteed party triggers the obligation of the Company . As of March 31, 2004, all indemnifications included in agreements as of that date are excluded from the scope of FIN No . 45 as they relate primarily to our own future performance and do not require any contingent payments .

As of March 31, 2004, our total contractual commitments on loans, operating leases, and royalty agreements have not materially changed since December 31, 2003, as disclosed in our Report Form 10-K .

NOTE 10 . CHANGES IN SECURITIES

As part of the strategic alliance agreement that we entered into with a subsidiary of Teva Pharmaceutical Industries Ltd . (Teva) in June 2001, we received $22 .0 million from Teva which assisted in the construction and improvement of our Hayward, California facilities and the development of the twelve products specified in our strategic alliance agreement . The $22 .0 million was reflected on the balance sheet as a refundable deposit . The refundable deposit was provided in the form of a loan . Pursuant to the agreement, accrued and future interest on the refundable deposit was forgiven during 2002 as a result of our receipt of tentative or final approvals for at least three of our products . In addition, Teva forgave portions of this loan as we achieved certain milestones relating to the development and launch dates of the products described in our strategic alliance agreement . In addition, by requiring us to repay only 50t of the portion of the loan related to certain missed milestones, Teva chose to continue to have exclusive marketing rights for those products . At our option, we could repay Teva any amounts we owed it as part of the loan in cash or in shares of our common stock . The price of the common stock for purposes of repaying any amounts owed under the loan was the average closing sale price of our common stock measured over a ten-trading-day period ending two days prior to repayment .

In September 2003, we issued 888,918 shares of common stock to Teva, paying $13 .5 million of the original $22 .0 million refundable deposit . In December 2003, Teva exercised its option to retain marketing exclusivity for certain products and, accordingly, reduced the refundable deposit by $3 .5 million to $5 .0 million . In January 2004, Teva's exercise of the marketing exclusivity option for certain products reduced the refundable deposit to $2 .5 million . On January 15, 2004, we satisfied the remaining $2 .5 million refundable deposit obligation to Teva by issuing 160,751 shares of our common stock to Teva . These shares were issued to Teva without registration under the Securities Act of 1933, as amended, in reliance upon the exemption from registration provided by Section 4(2) of the Securities Act of 1933 .

On January 30, 2004, the holders of the Series 2 Preferred Stock converted their entire 75,000 preferred shares into 1,500,000 shares of common stock .

NOTE 11 . RESTATEMENT OF CONDENSED FINANCIAL STATEMENT S

Subsequent to the issuance of its condensed financial statements for the three months ended March 31, 2004, the Company determined that, based on information provided by Teva, its strategic partner, i) customer credits on sales of bupropion were not recorded in the proper periods, ii) the sales returns reserve was not properly recorded, and iii) sales invoices prepared by Teva, were incorrectly prepared . The impact of correcting these errors and reducing taxable income caused the previous tax provision to be reversed . As a result, the accompanying condensed financial statements for the three months ended March 31, 2004 have been restated from the amounts previously reported .

A summary of the effects of the restatement is as follows ;

GENERA L

Impax Laboratories, Inc . was formed through a business combination on December 14, 1999 between Impax Pharmaceuticals, Inc ., a privately held drug delivery company, and Global Pharmaceutical Corporation, a generic pharmaceutical company . Impax Pharmaceuticals, Inc . merged with and into Global, with Impax stockholders receiving 3 .3358 shares of Global common stock for each share of Impax Pharmaceuticals, Inc . At the conclusion of the merger, Impax Pharmaceuticals, Inc . stockholders held over 70% of the combined company . For accounting purposes, the merger has been treated as a recapitalization of Impax Pharmaceuticals, Inc . with Impax Pharmaceuticals, Inc . deemed the acquirer of Global in a reverse acquisition . As a reverse acquisition, our historical operating results prior to the merger are those of Impax Pharmaceuticals, Inc . and only include the operating results of Global after the merger . In connection with the merger, the surviving company changed its name to Impax Laboratories, Inc . we are a technology based, specialty pharmaceutical company applying formulation and development expertise, as well an our drug delivery technology, to the development of controlled-release and niche generics, in addition to the development of branded products . An of March 31, 2004, the Company markets thirty-three generic pharmaceuticals, which represent dosage variations of fourteen different pharmaceutical compounds, and have seventeen applications pending at the FDA, including five tentatively approved, that address approximately $5 .4 billion in U .S . product sales for the twelve months ended February 29, 2004, according to NDCHealth . Thirteen of these pending filings were made under Paragraph IV of the Hatch-Waxman Amendments . We have approximately twenty-seven other products in various stages of development for which applications have not yet been filed . These products are generic versions of pharmaceutical products that had U .S . sales of approximately $14 .5 billion for the twelve months ended February 29, 2004, according to NDCHealth . CRITICAL ACCOUNTING POLICY RELATED TO REVENUE RECOGNITION

The Company recognizes revenue in accordance with SEC Staff Accounting Bulletin ("SAB") 101 issued by the SEC in December 1999 . We recognize revenue from the sale of products when the shipment of products is received and accepted by the customer . Provisions for estimated discounts, rebates, chargebacks, returns and other adjustments are provided for in the period the related sales are recorded . In December 2003, the SAB 104 was issued by the SEC . This bulletin revises and clarifies portions of Topic 13 of the Staff Accounting Bulletin to be consistent with current accounting and auditing guidance and SEC rules and regulations .

Emerging Issues Task Force (EITF) No . 00-21 supplemented SAB 101 for accounting for multiple element arrangements . The Company has entered into several strategic alliances that involve the delivery of multiple products and services over an extended period of time . In multiple element arrangements, the Company must determine whether any or all of the elements of the arrangement can be separated from one another . If separation is possible, revenue is recognized for each deliverable when the revenue recognition criteria for the specific deliverable is achieved . If separation is not possible, revenue recognition is required to be spread over an extended period .

Under EITF No . 00-21, in an arrangement with multiple elements , the delivered item should be considered a separate unit of accounting if all of the following criteria are met :

1) the delivered item has value to the customer on a standalone basis ; 2) there is objective and reliable evidence of the fair value of the undelivered item ; and 3) if the arrangement included a general right of return, or whether delivery or performance of the undelivered item is considered probable .

13 The Company reviews all of the terms of its strategic alliances and follows the guidance from EITF No . 00-21 for multiple element arrangements .

In June 2001, the Company entered into a Strategic Alliance Agreement with a subsidiary of Teva for twelve controlled-release generic pharmaceutical products . The agreement granted Teva exclusive U .S . prescription marketing rights for these products for a period of ten years from the date of Teva's first sale of the products . Under the terms of this agreement, Teva has sole and exclusive right to determine all terms and conditions of sale to its customers, including pricing discounts, allowances, price adjustments, returns and rebates .

Revenues from product sales for these products under our strategic alliance are recognized at the time title and risk of loss transfers to Teva's customers . During the three months ended March 31, 2004, the Company commenced shipping its Bupropion Hydrochloride 100 mg and 150 mg Controlled Release Tablets . Teva ships the Bupropion products to its customers and reports the results on a monthly basis . Teva provides to IMPAX a financial report detailing its gross sales less applicable chargebacks, rebates and other credits to arrive at net sales, cost of sales information and gross margins for the Bupropion products . The Company is endeavoring to take steps under the Strategic Alliance Agreement to ensure that all such adjustments granted by its strategic partner in the future are reported to the Company on a timely basis . These steps include, but are not limited to, regular discussions with Teva management regarding their monthly financial reports to IMPAX on our products marketed by Teva via monthly teleconferences and quarterly meetings . These discussions will cover all the areas of revenue recognition for these products, including but not limited to, Bales credits, product returns and internal controls over Teva's financial reporting to IMPAX . Our procedures will include a review of applicable documentation for IMPAX revenue sharing . The Audit Committee of the Company's Board of Directors may take additional steps as deemed necessary . Under the terms of the contract, the Company has the option to perform an annual audit with our strategic partner . The information on the financial report is used by IMPAX to record its monthly revenue for the Bupropion 100 mg and 150 mg products . Effective with the three months ended March 31, 2004, we began estimating returns for prescription products marketed by our strategic partners, such as Teva, called "Rx Partners," based on our internal returns analysis and historical industry statistics . Additionally, the amount of revenue that IMPAX earns is based on a reimbursement of manufacturing costs plus a fixed gross margin percentage .

Under the July 2003 Exclusivity Transfer Agreement with Andrx and Teva pertaining to the Bupropion Hydrochloride products, Andrx is entitled to certain payments for the sales of the 150 mg strength for a 180-day period from the product launch date . These payments are made directly by Teva to Andrx .

RESULTS OF OPERATION S

Except for the three months ended March 31, 2004, we have incurred net losses in each quarter since our inception . we had an accumulated deficit of $99,333,000 at March 31, 2004 .

THREE MONTHS ENDED MARCH 31, 2004, COMPARED TO THREE MONTHS ENDED MARCH 31, 2003

OVERVIEW

The net income for the three months ended March 31, 2004, was $5,216,000 as compared to a net loss of $3,213,000 for the three months ended March 31, 2003 .

REVENUE S

Revenues for the first quarter of 2004 were a record $34,545,000, up more than 2021 compared with revenues of $11,425,000 in the prior year's first quarter . The year-over-year increase for the first quarter was primarily due to shipments of our generic versions of Wellbutrin(R) SR (Bupropion Hydrochloride) 100 mg and 150 mg Controlled Release Tablets, both of which were approved by the FDA during the quarter and represented approximately 57% of total revenues . During the quarter, upon approval from the FDA, we also commenced shipments of Demeclocycline Hydrochloride (Declomycin(R)) 150 mg and 300 mg Tablets .

The company generated $3,031,000 of other revenues in the 2004 period, as compared to $359,000 in the 2003 period . Other revenue for the 2004 period consisted of $2,500,000 from Teva, which represented the reversal of a portion of the refundable deposit for its exercise of the exclusivity option for certain

14 products . The balance of $531,000 of other revenue represents revenues recognized pursuant to strategic agreements with Schering-Plough, Wyeth, and Novartis . The following table summarizes the activity in net revenues for the three months ended March 31, 2004 and 2003)

The rebates, chargebacks, returns and other credits decreased for the three months ended March 31, 2004 to approximately 17% of product sales as compared to approximately 220 for the comparable period in 2003 . This decrease was due to Supropion Hydrochloride 100 mg and 150 mg Controlled Release Tablets and sales of Loratadins and Pseudoephedrine Sulfate (5sg/110ag) 12-hour Extended Release Tablets which are exempt from rebates, chargebacks and other credits as per the agreements with Schering-Plough, Wyeth, and Novartis . The increase in the reserve for sales returns was primarily due to returns for LIPRAM products, and products marketed by Rx Partners .

ITEM 3 . QUAXTITATIVR AND QUALITATIVE DISCLOSURES ABOUT MARK= RIS K

The Company's cash and cash equivalents includes U .S . government and short term commercial paper stated at cost which approximates market value . The primary objective of the Company's investment activities is to preserve principal while, at the same time, maximise yields without significantly increasing risk . To achieve this objective, the Company maintains its portfolio in a variety of high credit quality securities, including U .S . Goverment securities, treasury bills, and short-term commercial paper . one hundred percent of the Company's portfolio matures in l ess than one year . The carrying value of the portfolio approximates the market value at March 31, 2004 . The Company's debt instruments at March 31, 2004, are subject to fixed and variable interest rates and principal payments . We belie" that the fair value of our fixed and variable rate long-term debt approximates their carrying value of approximately $16 .6 million at March 31 . 2004 . While changes in market interest rates may affect the fair value of our fixed and variable rate long-term debt, we believe the offset . if any, of reasonably possible near-term changes in the fair value of such debt on the Company's financial statements will not be material . We have no interest rate or derivative financial instruments nor material foreign exchange risks . We are also not party to any off-balance-shoot arrangements, other than operating leases .

ITEM 4 . CONTROLS AND PROCEDURE S

The Company, under the supervision and with the participation of our management, including our principal executive officer and our principal financial officer, evaluated the effectiveness of our disclosure controls and procedures (as defined in Exchange Act Rule 13a-16(e)), as of the end of the period covered by this report . Based on this evaluation, including consideration of the restatement discussed below, our principal executive officer and our principal financial officer concluded that our disclosure controls and procedures are effective in reaching a reasonable level of assurance that information required to be disclosed by us in the reports that we file or submit under the Securities Exchange Act of 1934, as amended, is recorded, processed , summarised, and reported within the time period specified in the Securities and Exchange Commission's rules and forms .

The principal executive officer and principal financial officer also conducted an evaluation of internal control over financial reporting ('Internal control-) to determine whether any changes in internal Controls occurred during the quarter that have materially affected, or which are reasonably likely to materially affect, Internal Controls . Rased on this evaluation, there has been no such change during the quarter covered by this report .

A control system, no matter how we ll conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met . Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs . Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within the Company have been detected . The company conducts periodic evaluations of its internal controls to enhance, where necessary, its procedures and controls . Because of the inherent limitations in a cost-effective control system . misstatements due to error or fraud may occur and not be detected . Subsequent to issuance of the condensed financial statements for the quarter ended March 31, 2004, the Company restated its condensed financial statements as described in Note 11 . The Company determined that a material weakness existed in its internal controls . The Company is endeavoring to take steps to correct the deficiency that gave rise to this restatement . These steps include, but are not limited to, regular discussions with Teve management regarding their monthly financial reports to IMPAX on our products marketed by Teva via monthly teleconferen ces and quarterly meetings . These discussions will cover all the areas of revenue recognition for these products , including but not limited to, sales credits , product returns and internal controls over Teva ' s financial report ing to IMPAX. Our procedures will include a review of applicable documentation for IMPAX revenue sharing . The Audit Committee of the Company's Board of Directors may take additional steps as deemed necessary . The Company is endeavoring to take steps under the strat egic Alliance Agreement to ensure that all such adjustments granted by its strategic partner in the future are repo rted to the Company on a timely basis . Under the contract terms, the Company has the option to perform an annual audit with our strategic partner . The Company has disclosed and discussed this with its Audit Committee . For more information concerning the res tatement , sea note 11 in the Notes to f inancial Statements contained in the Company's Quart erly Report an Form 10 - Q/A for the quarter ended March 32, 3004 .

PART It - OTHZR INFORMATION

ITEM 1 . LEGAL PROCSIDINGS

PATENT LITIGATION

There has been substantial litigation in the pharmaceutical, biological, and biotechnology industries with respect to the manufacture . use, and sale of now products that are the subject of conflicting patent rights . one or more patents cover most of the brand name controlled -release products for which we are developing generic versions . Under the Hatch-Waxman Amendments, when a drug developer files an ANDA for a generic drug , and the developer believes that an unexpired patent which has been listed with the FDA as covering that brand name product will not be infringed by the developer ' s product or is invalid or unenforceable , the developer must so certify to the FDA . That cert ification must also be provided to the patent holder , who may challenge the developer's certification of non - infringement , invalidity or unenforceability by filing a suit for patent infringement within 45 days of the patent holder's receipt of such ce rtification . If the patent holder files suit , the FDA can review and approve the AMDA, but is prevented from granting final marketing approval of the product until a final judgment in the action has been rendered, or 30 months from the date the ce rt ification was received, whichever is sooner . should a patent holder com mence a lawsuit with respect to an alleged patent infringement by us, the uncertainties inherent in patent litigation wake the outcome of such litigation difficult to predict . The delay in obtaining FDA approval to market our product candidates as a result of litigation , as well as the expense of such litigation , whether or not we are successful , could have a material adverse effect on our results of operations and financial position . In addition, there can be no assurance that any patent litigation will be resolved prior to the 30-month period . As a result , even if the FDA were to approve a product upon expiration of the 30-month period, we may not commence, marketing that product if patent litigation is still pending .

Lawsuits have been filed against us in connection with fourteen of our Paragraph IV filings . The outcome of such litigation is difficult to predict because of the uncertainti es inherent in patent litigation .

ASTRAZI RCA AR BT AL . V . IMPAXs THE OMRPRAZOLI CARE R

In May 1000 , Astrafeneca AS and four of its related companies filed suit against IMPAX in the U .B . District Court in Wilmington, Delaware claiming that IMPAX's submission of an AM for Qaeprasole Delayed Release Capsul es, 10 mg and 20 y, constitutes infringement of six U .B . patents relating to Astraseneca ' s Prilosec product . The action seeks an order enjoining IMPAX from marketing Ceaprazole Delayed Release Capsules , 10 as and 20 as until Februa ry 4, 301 4, and awarding costs and attorney fees . There is no claim for damages .

In February 2001 , Astrafenecs and the same related companies filed the some suit against IMPAR in the aau federal cou rt in Delaware for Infringement , based upon IMPAX ' s amendment to its AMDA adding 40 as strength Dseprazole Delayed Release Capsules .

Astraieneca filed essentially the saw lawsuits against nine other generic pharmaceutical companies (Andrx , Qenpharm , Cheminor, Kreaers . LZK, ton , Nylon, Apotex, and Zenith) . Due to the numbe r of these cases, a nultidlatrict litigation proceeding , In re Oeeprasole 10 mg . 20 wag, and 40 mg Delayed Released Capsules Patent Litigation, MDL-1391 , has b een established to coordinate pro-trial proceedings . Roth lawsuits filed by Astrateneca against IMPAX have been transferred to the sultidistrict litigation .

Early in the multidistrict litigation , the trial court ruled that one of the six patent s- in- suit was not infringed by the sale of a generic oaieprasole product and that certain other patents were invalid . These rulings effectively eliminated four patents from the trial of these infringement cases, although Astrateneca may appeal these rulings ae part of the overall appeal process in the case .

On October 11, 2002, after a trial involving Andrx , uenphar. . Cheainor, and Rresers, the trial judge handling the aultidistrict litigation ruled on Astrateneca ' s complaints that three of these four defendants (First wave Defendants) infringed the remaining patents- in-suit . The trial judge ruled that three of the First Wave defendants , Andrx . Oenphar m , and Chemins, infringed the remaining two patents a sserted by Astrazeneca in its complaints , and that those patents are valid until 2007 . In the same ruling , the trial court ruled that the remaining First Wave Defendant , Krewers , did not infringe either of th e remaining two patents . This defendant's formulation differed from the formulation used by the other First Wave Defendants in several respects . In mid-December 2003 , the U .S . Court of Appeals for the Federal Circuit affirmed the October 3002 ruling in all respects . Subsequent petitions for rehearing have been denied .

The formulation that IMPAX would employ in manufacturing its generic equivalent of o.eprasole has not been publicly announced . IMPAX ' ■ formulation has elements that res emble those of other First Nave Defendants , but It also has elements that differ . Although the ruling by the trial court in the multidistrict litigation has a significant effect on the course of Aatraseneca ' e litigation against IMPAX , application of the trial court ' s opinion is not certain . IMPAX believes that it has defenses to Astrafeneca's claims of infringement , but the opinion rendered by the trial court in the First Wave cases makes the outcome of AstraZeneca ' s litigation against IMPAX uncertain .

Two of the remaining six defendants ( Second Wave Defendants ) filed Notions for Summary Judgment of Non - Infringement , based upon the October 2002 ruling . The trial court has deferred ruling on those motions until discove ry is completed .

In December 3003 , the trial court entered a new scheduling order gove rn ing pre-trial proceedings relating to the Second Wave Defendants, including IMPAX . The schedule for completion of the litigation in the Second Wave, Including Astraseneca ' s litigation against IMPAX, now provides that all fact discove ry (with certain exceptions ) is complete . Astraseneca ' a expert reports on issues as to which it bears the burden of proof , including issues of alleged infringeme nt, were produced on Februa ry 17 , 2004 . IMPAX ' ■ responsive expert reports will be completed by July 12 , 3004 . Any rebuttal report s by Astrazeneca will be required to be produced by August i, 2004 . The parties have not submitted their joint schedule for expert depositions to the Special Master and the Special Master has not iss ued an order reg arding expert depositions . Depositions of the pa rt ies' expe rt s are expected to occur thereafter and to be completed by aid-December 2004 . Notions for Summary Judgment and responses must be filed and fully briefed by November 1 6 , 2004 . given the delays which have thus far occurred in the litigation and the number of experts already designated by the parties, it is unce rtain whether the expe rt depositions can be completed in the time allotted by the present schedule .

Under the scheduling order, any further notions for summary Judgment must be filed by early fall, and they will be heard by the trial court after briefing is completed in November 2004 . IMPAX may file Motions for Summa ry Judgment, includi ng a Motion tome Summary Judgment of Non - Infringement , following the close of all discovery. If the cue is not resolved by summary judgment, the cam e involving IMPAX will be returned to the U .S . District Court in Delaware for trial . It is likely, given the proceedings in the First Wave eases , that the case against IMPAX will be transferred back to New York for a consolidated trial before the same judge who decided the First Wave cues . Trial will commence as soon as practicable thereafter . If IMPAX does not file a Notion for Summary Judgment , or if such a Motion is denied , the court will schedule a date for trial . IMPAX intends to vigorously defend the action brought by Astraseneca .

In August 2003 , the court issued an order dismissing four of the patents - in-suit, thr ee with prejudice . 00 September 30, 2003, as a result of the court ' s dismissal , Astraseneca served each of the second Wave Defendants, including IMPAX , with an a mended complaint . In October 2003, IMPAX filed an ans wer to the amended complaint in which we asserted a now counterclaim with antitrust all egations . The counterclaim will be severed , and proceedings relating to it will be stayed until after trial of the patent infringement case .

GLAXOSMITNKLINR (0X.AXO) V . IMPAXI TNN SUPROPIOI CASKS

Glaze filed a Complaint (Case No . 00-04403) against IMPAX in the U .S . District Court for the Northern District of California on November 3, 2000 alleging infringement of U .S . Patent No . 5,427 , 796 covering Wellbutrin OR and Zyban . On November 7 , 2000, INPAX filed its Answe r to the Complaint which included defenses to the infringement claim, and counterclaimed for patent invalidity .

POROUS PHARMA L .P . BY AL . V IMPAX , THE OXYC0D0NS CASES

On April 11 , 2002 , Purdue Pharma and related companies filed a complaint in the U .B . District Court for the Southern District of New York alleging that IMPAX' ■ submission of ANDA No . 76-318 for 60 mg OxyContin Tablets infringes three patent s owned by Purdue . The Purdue patents are U .S . Patent Nos . 4,$6l,S95, 4,970 , 075 and 5 , 266,331, all directed to controlled release opioid formulations . On September 19, 2002 , Purdue filed a second Infringement Complaint regarding INPAX' s 40 mg OxyContin generic product . On October 9, 2002 , Purdue filed a third infringement Complaint regarding IMPAX' s 10 mg and 20 mg Oxycontin generic products . IMPAX filed its waver and counterclaims in each case on October 3 . 2003 . On November 25, 2003 , Purdue submitted their reply to our counterclaim . Purdue is seeking, among other things , a court order preventing IMPAX from manufacturing , using or selling any drug product that infringes the subject Purdue patents . IMPAX had disputed jurisdiction of the Now York cou rts and brought an action for a Declaratory Judgment of Patent Invalidity in Delaware . The Now York court denied IMPAR ' a Notion to Dismiss and the Delaware action was dismissed .

Purdue previously sued Boehringer lagelbeie/Roxane, Undo and Teva on the same patents . One or more of these defendants may resolve the Invalidity issues surrounding the Purdue patents prior to IMPAX ' a ease goes to trial . The Soehringer Ingelheie / Roxane suit is stayed . The Sndo action was tried in June 2003 and post trial briefs have been filed . In January 200 4, the judge in the Soda action ruled that the three patents in suit , the Sane patents that Purdue had "sorted against IMPAX , are unenforceable because they were inequitably procured and enjoined their enforcement . There can be no assurances that such ruling will not be challenged or, if sustained upon challenge , that the rulings in IMPAX ' s cases will be consistent with such rulings .

IMPAX V . AVUNTIS PNARMRCSUTICALB , INC ., THE RILUZOLR CAS E

In June 2002 , IMPAX filed suit against Aventi ■ Pharmaceuticals, Inc . in the U .S . District Court in Wilmington , Delaware , seeking a declaration that the filing of an ANDA to engage in a commercial manufacture and/or sale of Rilusole 50 ey Tablets for treatment of patients with a .yotrophic lateral sclero ses (ALS) does not infringe claims of Aventis ' U .S . Patent No . 5,527 , 614 ('114 patent) and a declaration that this patent is invalid .

In response to IMPAX ' s complaint , Aventis filed counterclaims for direct infringement and inducement of infringement of the ' 114 patent . In December 2002, the district court granted Aventis ' Notion for Preliminary Injunction and enjoined IMPAX from infringing , contributory infringing, or inducing any other person to infringe Claims 1, 4 or S of the '814 patent by selling, offering for sale, distributing, marketing or exporting from the United States any pharmaceutical product or compound containing rilusole or salt thereof for the treatment of ALS .

The trial was completed on October 30, 2003, and post-trial briefing was completed in December 2003 . IMPAX is pursuing its assertions that claims of the '814 patent are invalid in view of prior art and are unenforceable in view of inequitable conduct committed during the prosecution of the patent before the United States Patent and Trademark Office (USPTO) .

On January 30, 2004, the court denied IMPAX's Motion for Summary Judgment on inequitable conduct and, on February 5, 2004, the court denied IMPAX's Motion for Summary Judgment on non-infringement of certain claims . The court has not issue its trial rulings and did not rule on the third pre-trial Motion for Summary Judgment based on invalidity of the patent-in-suit .

If IMPAX is not ultimately successful in proving invalidity or unenforceability, there is a substantial likelihood that the court will enter a Permanent Injunction enjoining IMPAX from marketing Riluzole 50 .ge Tablets for the treatment of ALE in the United States until the expiration of the -814 patent (June 18, 2013) . If IMPAX is ultimately successful in proving either defense, the Preliminary Injunction would be set aside and IMPAX would be permitted to market its Riluzole 50 mg Tablet product for the treatment of ALS in the United States .

In March 2003, Abbott and Fournier filed a second action against IMPAX in the same court making the same claims against IMPAX's 54 mg Fenofibrate Tablets . These cases were consolidated in April 2003 .

In September 2003, Abbott and Fournier filed a third action against IMPAX in the U .S . District Court in Wilmington, Delaware, claiming that IMPAX's submission of its ANDA for 54 mg and 160 mg Fenofibrate Tablets constitutes infringement of a third patent recently issued to Fournier and exclusively licensed to Abbott .

All four cases were consolidated in March 2004 . Discovery in the consolidated cases closes in June 2004 and the trial is currently set for June 2005 . IMPAX has responded to all four complaints by asserting that its proposed generic Fenofibrate Tablet products do not infringe the patents-in-suit and by asserting that the patents-in-suit are invalid .

All four actions seek an injunction preventing IMPAX from marketing its Fenofibrate Tablet products until the expiration of the patents (January 9, 2018) and an award of damages for any commercial manufacture, use, or sale of IMPAX's Fenofibrate Tablet product, together with costs and attorney fees .

OTHER LITIGATION

STATE OF CALIFORNIA V . IMPAX

On August 7 , 2003 , IMPAX received an Accusation from the Department of Justice, Bureau of Narcotic Enforcement , State of California (" BNE'), alleging that IMPAX failed to maintain adequate controls to safeguard precursors from theft or loss regarding our pseudoephedrine product in Janua ry 2003 . IMPAX contested the allegations in the Accusation and entered into discussions with the state of California , Department of Justice , to bring resolution to this matter . IMPAX has implemented a number of remedial measures aimed at improving the security and accountability of precursor substances used by IMPAX and regulated by the Califo rn ia Department of Justice, Bureau of Narcotic Enforcement . In March 2004, following a theft of pseudoephedrine from IMPAX's facilities , the SHE filed an Amended Accusation , again alleging that IMPAX failed to maintain adequate controls to safeguard precursors from theft or loss regarding our pseudoephedrins product . IMPAX is continuing its discussions with the State of California , Department of Justice , and hopes to resolve this matter without the need for a formal hearing .

Other than the legal proceedings described above, we are not aware of any other material pending or threatened legal actions, private or governmental , against us . However , as we file additional applications with the FDA that contain Paragraph IV Certifications and develop now products , it is likely we will become involved in additional litigation related to those filings or products .

INSURANCE As part of our patent litigation strategy, we had obtained two policies covering up to $ 7 million of patent infringement liability insurance from American International Specialty Line Company ("AISLIC "), an affiliate of AIO International . This litigation insurance covered us a gainst the costs associated with patent infringement claims made against us relating to seven of the ANDAs we filed under Paragraph IV of the Hatch - Waxman Amendments . Both policies had reached their limits of liability . While Teve has agreed to pay 45• to 50% of the attorneys ' fees and costs (in excess of the $ 7 million expected to be covered by our insurance policie s for six products ) related to the twelve products covered by our strategic alliance agreement with them, we will be responsible for the remaining expenses and costs for these products , and all of the costs associated with patent litigation for our other products and our future products .

However , we do not believe that this type of litigation insurance will be available to us on acceptable terms for our other current or future ANDA5 . In those cases, our policy in to record such expenses as incurred . Product liability claims by customers constitute a risk to all pharmaceutical manufacturers . we carry $20 million of product liability insurance for our own manufactured products . This insurance may not be adequate to cover any product liability claims to which we may become subject .

STRATEGIC ALLIANCE AGREEMENT WITH TCVA

As part of the strategic alliance agreement that we entered into with a subsidiary of Teva Pharmaceutical Industries Ltd . (Teve) in June 2001, we received $22 .0 million from Teve which assisted in the construction and improvement of our Hayward, California facilities and the development of the twelve products specified In our strategic alliance agreement . The $22 .0 million was reflected on the balance sheet as a refundable deposit . The refundable deposit was provided in the form of a loan . Pursuant to the agreement, accrued and future interest on the refundable deposit was forgiven during 2002 as a result of our receipt of tentative or final approvals for at least three of our products . In addition, Teva forgave portions of this loon as we achieved certain milestones relating to the development and launch dates of the products described in our strategic alliance agreement . In addition, by requiring us to repay only 50% of the portion of the loan related to certain missed milestones, Teva chose to continue to have exclusive marketing rights for those products . At our option, we could repay Teve any amounts we owed it as part of the loan in cash or in shares of our common stock . The price of the common stock for purposes of repaying any amounts owed under the loan was the average closing sale price of our common stock measured over a ten-trading-day period ending two days prior to repayment .

In September 2003, we issued 515,916 shares of common stock to Tevs, paying . In December $13 .5 million of the original $22 .0 million refundable deposit 3003, Teva exercised its option to retain marketing exclusivity for certain .5 million to products and, accordingly . reduced the refundable deposit by $3 $9 .0 million . In January 2004, Teva's exercise of the marketing exclusivity option for certain products reduced the refundable deposit to $2 .5 million . On January 15, 2004, we satisfied the remaining $2 .5 million refundable deposit obligation to Teva by issuing 260,151 shares of our common stock to Teva . These shares were issued to Teva without registration under the Securities Act of 1933, as amended, in reliance upon the exemption from registration provided by Section 4(2) of the Securities Act of 1933 .
