Forward-Looking Statements
     We have made “forward-looking statements” in this document within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934, as amended. These statements, including estimates of future net sales, future net income and future earnings per share, contained in the section titled “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” are subject to risks and uncertainties. Forward-looking statements include the information concerning our possible or assumed results of operations. Also, statements including words such as “believes,” “expects,” “anticipates,” “intends,” “estimates,” or similar expressions are forward-looking statements. We have based these forward-looking statements on our current expectations and projections about the growth of our business, our financial performance and the development of our industry. Because these statements reflect our current views concerning future events, these forward-looking statements involve risks and uncertainties. Investors should note that many factors, as more fully described in “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and elsewhere in this Report could affect our future financial results and could cause our actual results to differ materially from those expressed in forward-looking statements contained in this Report. Important factors that could cause our actual results to differ materially from the expectations reflected in the forward-looking statements in this Report include, among others:
    Our growth and development will depend on our ability to successfully develop, commercialize and market new products, including both our own products and those developed with our collaboration partners. If we do not do so successfully, our growth and development will be impaired.
 
    Timing and results of clinical trials to demonstrate the safety and efficacy of products as well as the FDA’s approval of products are uncertain. Before obtaining regulatory approvals for the sale of any of our products, other than generic products, we must demonstrate through preclinical studies and clinical trials that the product is safe and effective for each intended use. Preclinical and clinical studies may fail to demonstrate the safety and effectiveness of a product. Even promising results from preclinical and early clinical studies do not always accurately predict results in later, large-scale trials. A failure to demonstrate safety and efficacy would result in our failure to obtain regulatory approvals.
 
    We face intense competition for the business of our branded and generic products, and in connection with our acquisition of rights to intellectual property assets. Competitive factors include: (i) the development of new products by our competitors that make our products or technologies uncompetitive or obsolete, (ii) competition with our branded products by generic versions that are generally significantly cheaper than the branded version, and, where available, may be required or encouraged in preference to the branded version under third-party reimbursement programs, or substituted by pharmacies for branded versions by law, and (iii) competition to acquire intellectual property assets that we require to continue to develop and broaden our product range.
 
    We are required to make significant cash payments to Endo Pharma LLC pursuant to a tax sharing agreement under which we have been and may be required to pay Endo Pharma LLC the amount of tax benefits usable by us as a result of the exercise of certain stock options into shares of our common stock held by Endo Pharma LLC.
 
    Once approved by FDA, there is no guarantee that the market will accept our future products, and this may have an adverse effect on our profitability and cash flows.
 
    The pharmaceutical industry is heavily regulated, which creates uncertainty about our ability to bring new products to market and imposes substantial compliance costs on our business. The federal, state and local governmental authorities in the United States, the principal one of which is the FDA, impose substantial requirements on the development, manufacture, labeling, sale, distribution, marketing, advertising, promotion and introduction of therapeutic pharmaceutical products through lengthy and detailed laboratory and clinical testing and other costly and time-consuming procedures. NDA approvals, if granted, may not include all uses for which we may seek to market a product. The FDA actively enforces regulations prohibiting marketing of products for non-indicated uses. Failure to comply with applicable regulatory requirements in this regard can result in, among other things, suspensions of approvals, seizures or recalls of products, injunctions against a product’s manufacture, distribution, sales and marketing, operating restrictions, civil penalties and criminal prosecutions. Furthermore, changes in existing regulations or the adoption of new regulations could prevent us from obtaining, or affect the timing of, future regulatory approvals. The effect of government regulation may be to delay marketing of our new products for a considerable period of time, to impose costly procedures upon our activities and to furnish a competitive advantage to larger companies that compete with us. We cannot assure you that the FDA or other regulatory agencies will approve any products developed or in-licensed by us on a timely basis, if at all, or, if granted, that approval will not entail limiting the indicated uses for which we may market the product, which could limit the potential market for any of these products.

    Most of our net sales come from a small number of products. Net sales of Lidoderm®, Endocet®, Percocet® and generic morphine sulfate accounted for 50%, 19%, 14% and 10% of our net sales for the year ended December 31, 2004, respectively. In addition, during the three months ended June 30, 2005 we launched our generic extended-release oxycodone product which accounted for 15% of our net sales. If we were unable to continue to market any of these products, if any of them lost market share, for example, as the result of the entry of new competitors, or if the prices of any of these products declined significantly, our net sales, profitability and cash flows would be materially adversely affected.
 
    We are dependent on outside manufacturers for the manufacture of our products. Third-party manufacturers currently manufacture all of our products pursuant to contractual arrangements. Accordingly, we have a limited ability to control the manufacturing process or costs related to this process. Increases in the prices we pay our manufacturers, interruptions in our supply of products or lapses in quality could adversely impact our margins, profitability and cash flows. We are reliant on our third-party manufacturers to maintain the facilities at which they manufacture our products in compliance with FDA, DEA, state and local regulations. If they fail to maintain compliance with FDA, DEA or other critical regulations, they could be ordered to cease manufacturing which would have a material adverse impact on our business, profitability and cash flows. In addition to FDA and DEA regulation, violation of standards enforced by the Environmental Protection Agency, or EPA, and the Occupational Safety and Health Administration, or OSHA, and their counterpart agencies at the state level, could slow down or curtail operations of third-party manufacturers. Certain of our manufacturers currently constitute the sole source of one or more of our products. Because of contractual restraints and the lead-time necessary to obtain FDA approval, and possibly DEA registration, of a new manufacturer, replacement of any of these manufacturers may be expensive and time consuming and may cause interruptions in our supply of products to customers.
 
    We are dependent on third parties to supply all raw materials used in our products and to provide many services for the core aspects of our business. Any interruption or failure by these suppliers, distributors and collaboration partners to meet their obligations pursuant to various agreements with us could have a material adverse effect on our business, profitability and cash flows.
 
    Most of our core products contain narcotic ingredients. As a result of reports of misuse or abuse of prescription narcotics, the sale of such drugs may be subject to new regulation, including the development and implementation of risk management programs, which may prove difficult or expensive to comply with, and we and other pharmaceutical companies may face lawsuits.
 
    We are exposed to product liability claims or product recalls and the possibility that we may not be able to obtain or maintain insurance adequate to cover these potential liabilities. Our business exposes us to potential liability risks that arise from the testing, manufacturing, marketing and sale of our products. In addition to direct expenditures for damages, settlement and defense costs, there is a possibility of adverse publicity as a result of product liability claims. Product liability is a significant commercial risk for us. Some plaintiffs have received substantial damage awards in some jurisdictions against pharmaceutical companies based upon claims for injuries allegedly caused by the use of their products. In addition, it may be necessary for us to recall products that do not meet approved specifications, which would also result in adverse publicity, as well as resulting in costs connected to the recall and loss of revenue.
 
    Our ability to protect our proprietary technology, which is vital to our business, is uncertain. Our success, competitive position and amount of potential future income will depend in part on our ability to obtain patent protection relating to the technologies, processes and products we are currently developing and that we may develop in the future.
 
    If the efforts of manufacturers of branded pharmaceuticals to use litigation and legislative and regulatory efforts to limit the use of generics and certain other products are successful, our sales may suffer. Pharmaceutical companies that produce patented brand products are increasingly employing a range of legal and regulatory strategies to delay the introduction of competing generics and certain other products to which we do not have a right of reference to all necessary preclinical and clinical data. Opposing such measures can be costly and time-consuming and result in delays in the introduction of our products.
 
    The success of our acquisition and licensing strategy is subject to uncertainty and any completed acquisitions or licenses may reduce our earnings, be difficult to integrate, not perform as expected or require us to obtain additional financing. We regularly evaluate selective acquisitions and licenses and look to continue to enrich our product line by acquiring or licensing rights to additional products and compounds. Such acquisitions or licenses may be carried out through the purchase of assets, joint ventures and licenses or by acquiring other companies. However, we cannot assure you that we will be able to complete

Table of Contents

      acquisitions or licenses that meet our target criteria on satisfactory terms, if at all. In particular, we may not be able to identify suitable acquisition or licensing candidates, and we may have to compete for acquisition or license candidates. Our competitors may have greater resources than us and therefore be better able to complete acquisitions or license or may cause the ultimate price we pay for acquisitions to increase. If we fail to achieve our acquisition or license goals, our growth may be limited.
 
    The DEA limits the availability of the active ingredients used in many of our current products and products in development and, as a result, our procurement quota of these active ingredients may not be sufficient to meet commercial demand or complete clinical trials. We must annually apply to the DEA for procurement quota in order to obtain these substances. Pursuant to recent legislation, the DEA may not establish procurement quota following FDA approval of an NDA or ANDA for a controlled substance until after DEA reviews and provides public comment on the labeling, promotion, risk management plan and other documents associated with such product. No assurance can be given that the DEA review of such materials may not result in delays in obtaining procurement quota for controlled substances, a reduction in the quota issued to us or an elimination of our quota entirely. Any delay by the DEA in establishing our procurement quota for controlled substances could delay our clinical trials, product launches or could cause trade inventory disruptions for those products that have already been launched.
 
    The availability of third-party reimbursement for our products is uncertain, and thus we may find it difficult to maintain current price levels. Additionally, the market may not accept those products for which third-party reimbursement is not adequately provided. Our ability to commercialize our products depends in part on the extent to which reimbursement for the costs of these products is available from government health administration authorities, private health insurers and others. We cannot assure you that third-party insurance coverage will be adequate for us to maintain price levels sufficient for realization of an appropriate return on our investment. Government, private insurers and other third-party payers are increasingly attempting to contain health care costs by (1) limiting both coverage and the level of reimbursement for new products approved for marketing by the FDA, (2) refusing, in some cases, to provide any coverage for uses of approved products for indications for which the FDA has not granted marketing approval and (3) requiring or encouraging, through more favorable reimbursement levels or otherwise, the substitution of generic alternatives to branded products.
 
    The outcome of any litigation is uncertain, including claims asserting violations of the Federal False Claims Act, Anti-Kickback Statute or other violations in connection with Medicare and/or Medicaid; and
 
    We are dependent on sales to a limited number of large pharmacy chains and wholesale drug distributors for a large portion of our total net sales. We sell our products directly to a limited number of large pharmacy chains and through a limited number of wholesale drug distributors who, in turn, supply our products to pharmacies, hospitals, governmental agencies and physicians. Three distributors and one pharmacy chain individually accounted for 29%, 18%, 18% and 9% respectively, of net sales in 2004, 26%, 26%, 19% and 11% respectively, of net sales in 2003, and 24%, 24%, 23% and 11% respectively, of net sales in 2002. If we were to lose the business of any of these customers, or if any were to experience difficulty in paying us on a timely basis, our net sales, profitability and cash flows could be materially and adversely affected.
We do not undertake any obligation to update our forward-looking statements after the date of this Report for any reason, even if new information becomes available or other events occur in the future. You are advised, however, to consult any further disclosures we make on related subjects in our 10-Q, 10-K and 8-K reports to the SEC. Also note that we provide the preceding cautionary discussion of risks, uncertainties and possibly inaccurate assumptions relevant to our business. These are factors that, individually or in the aggregate, we think could cause our actual results to differ materially from expected and historical results. We note these factors for investors as permitted by the Private Securities Litigation Reform Act of 1995. You should understand that it is not possible to predict or identify all such factors. Consequently, you should not consider the preceding to be a complete discussion of all potential risks or uncertainties.

ENDO PHARMACEUTICALS HOLDINGS INC.
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(UNAUDITED)
FOR THE THREE AND SIX MONTHS ENDED JUNE 30, 2005
1. BASIS OF PRESENTATION
     The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission for interim financial information. In the opinion of management, the accompanying condensed consolidated financial statements of Endo Pharmaceuticals Holdings Inc. (the “Company” or “we”) and its subsidiaries, which are unaudited, include all normal and recurring adjustments necessary to present fairly the Company’s financial position as of June 30, 2005 and the results of our operations and our cash flows for the periods presented. The accompanying condensed consolidated balance sheet as of December 31, 2004 is derived from the Company’s audited financial statements. Since certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States have been condensed or omitted, we suggest that these condensed consolidated financial statements be read in conjunction with the consolidated financial statements and notes thereto as of and for the year ended December 31, 2004 contained in the Company’s Annual Report on Form 10-K. Certain prior period amounts have been reclassified to conform to the current period presentation.
2. RECENT ACCOUNTING PRONOUNCEMENTS
     In November 2004, the FASB issued Statement of Financial Accounting Standards No. 151, Inventory Costs, an amendment of ARB No. 43, Chapter 4. The purpose of this statement is to clarify the accounting of abnormal amounts of idle facility expense, freight, handling costs and waste material. ARB No. 43 stated that under some circumstances these costs may be so abnormal that they are required to be treated as current period costs. SFAS 151 requires that these costs be treated, as current period costs regardless if they meet the criteria of “so abnormal.” In addition, the statement requires that allocation of fixed production overheads to the costs of conversion be based on the normal capacity of the production facilities. The provision of this Statement shall be effective for inventory costs incurred during fiscal years beginning after June 15, 2005. The adoption of SFAS 151 is not expected to have a material impact on the Company’s results of operations or financial position.
     In December 2004, the FASB issued SFAS No. 153, Exchanges of Nonmonetary Assets, an amendment of APB Opinion No. 29. SFAS 153 is effective for nonmonetary asset exchanges occurring in fiscal periods beginning after June 15, 2005, with earlier application permitted. The adoption of SFAS 153 is not expected to have a material impact on the Company’s results of operations or financial position.
     In December 2004, the FASB issued SFAS No. 123R, Share-Based Payments (revised 2004). This statement eliminates the option to apply the intrinsic value measurement provisions of APB Board Opinion No. 25, Accounting for Stock Issued to Employees, to stock compensation awards issued to employees. Rather, the Statement requires companies to measure the cost of employee services received in exchange for an award of equity instruments based on the grant date fair value of the award. That cost will be recognized over the period during which an employee is required to provide services in exchange for the award — the requisite service period (usually the vesting period). In March 2005, the SEC staff expressed their views with respect to SFAS No. 123R in Staff Accounting Bulletin No. 107, Share-Based Payment, (SAB 107). SAB 107 provides guidance on valuing options. SFAS 123R will be effective for the Company’s fiscal year beginning January 1, 2006. The Company is currently evaluating the impact of the adoption of this statement on its financial statements.
     In March 2005, the FASB issued FASB Interpretation No. 47, Accounting for Conditional Asset Retirement Obligations, (FIN 47). FIN 47 is an interpretation of SFAS No. 143, Asset Retirement Obligations, which was issued in June 2001. FIN 47 was issued to address diverse accounting practices that have developed with regard to the timing of liability recognition for legal obligations associated with the retirement of a tangible long-lived asset in which the timing and/or method of settlement are conditional on a future event that may or may not be within the control of the entity. According to FIN 47, uncertainty about the timing and/or method of settlement of a conditional asset retirement obligation should be factored into the measurement of the liability when sufficient information exists. FIN 47 also clarifies when an entity would have sufficient information to reasonably estimate the fair value of an asset retirement obligation. FIN 47 is effective no later than December 31, 2005 for the Company. The Company is currently evaluating the impact of the adoption of FIN 47 on its financial statements.

     In May 2005, the FASB issued SFAS No. 154, Accounting Changes and Error Corrections, a replacement of APB Opinion No. 20 and Statement No. 3. SFAS 154 changes the requirements for the accounting and reporting of a change in accounting principle. SFAS 154 applies to all voluntary changes in accounting principle as well as to changes required by an accounting pronouncement that does not include specific transition provisions. SFAS 154 is effective for accounting changes and corrections of errors made in fiscal years beginning after December 15, 2005. The adoption of SFAS 154 is not expected to have a material impact on the Company’s results of operations or financial position.

4. LICENSE AND COLLABORATION AGREEMENTS
DURECT Corporation
     On March 14, 2005, we announced that we signed an agreement that gives us the exclusive license to develop and commercialize DURECT’s sufentanil-containing transdermal patch in the U.S. and Canada (the “DURECT Sufentanil Agreement”). The sufentanil patch, which is in early-stage clinical development, employs DURECT’s proprietary TRANSDUR™ drug-adhesive matrix formulation and is intended to provide relief of moderate-to-severe chronic pain for up to seven days. We have assumed all remaining development and regulatory filing responsibility for this product, including the funding thereof. Under the terms of the DURECT Sufentanil Agreement, in April 2005, we paid DURECT a $10 million upfront fee that has been expensed as research and development in the first quarter of 2005, with additional payments of approximately $35 million upon achievement of predetermined regulatory and commercial milestones. We will also pay royalties to DURECT on net sales of the sufentanil transdermal patch. In addition, the DURECT Sufentanil Agreement also contains terms and conditions customary for this type of arrangement, including representations, warranties, indemnities and termination rights. The DURECT Sufentanil Agreement will continue in effect until terminated. The DURECT Sufentanil Agreement provides each party with specified termination rights, including the right of each party to terminate the DURECT Sufentanil Agreement upon material breach of the DURECT Sufentanil Agreement by the other party and the right of Endo to terminate the DURECT Sufentanil Agreement at any time without cause subject to a specified notice period.
ProEthic Pharmaceuticals, Inc.
     On March 14, 2005, we entered into an agreement with ProEthic Pharmaceuticals, Inc. for the U.S. and Canadian rights to develop and commercialize a once-daily ketoprofen-containing topical patch. Ketoprofen is a non-steroidal anti-inflammatory drug (NSAID) generally used for the treatment of inflammation and pain and currently available in the U.S. only in oral form. Currently in Phase II clinical trials in the U.S., the ketoprofen patch is being developed for the localized treatment of acute pain associated with soft-tissue injuries such as tendonitis or joint sprains and strains. Two Phase III placebo-controlled studies in soft-tissue injury and ankle sprains have been completed in Europe by ProEthic’s European partner APR Applied Pharma Research AG, with statistically significant results. Under the terms of the agreement, in March 2005, we paid a $10 million upfront fee that has been expensed as research and development in the first quarter of 2005, and we could be required to make additional payments of approximately $13.0 million upon the achievement of certain regulatory and other milestones. We will also pay royalties on net sales of the ketoprofen patch. In addition, the license agreement also contains customary terms and conditions, including representations, warranties, indemnities and termination rights. The term of the license agreement shall be until the later of (i) the expiration of the patents or (ii) the tenth (10th) anniversary of the date of the first commercial sale of the product. We can terminate the agreement at any time upon no more than ninety (90) days’ written notice.

     SkyePharma, Inc.
     In December 2002, we entered into a Development and Marketing Strategic Alliance Agreement with SkyePharma, Inc. and SkyePharma Canada, Inc. relating to two of SkyePharma’s patented development products, DepoDur™, previously referred to as DepoMorphine™, and Propofol IDD-D™ (collectively, the “Skye Products”). Under the terms of the agreement, Endo received an exclusive license to the U.S. and Canadian marketing and distribution rights for the Skye Products, with options for certain other SkyePharma development products. In return, Endo made a $25 million upfront payment to SkyePharma, which we capitalized as an intangible asset representing the fair value of the exclusive license of these distribution and marketing rights. We were amortizing this intangible asset over its useful life of 17 years.
     During the six months ended June 30, 2005, we recorded a receivable from SkyePharma of $5 million based upon the achievement of certain criteria as specified in the agreement. This receivable has been recorded as a reduction to our recorded intangible asset and the intangible asset is now being amortized over its remaining useful life of 15 years.
Vernalis Development Limited
     On July 1, 2005, we entered into a co-promotion Agreement with Vernalis. The co-promotion agreement is related to that certain license agreement that we entered into on July 14, 2004 with Vernalis, under which Vernalis agreed to exclusively license to us rights to market the product Frova® (frovatriptan) in North America. Pursuant to the license agreement, Vernalis had retained rights to co-promote Frova® in the United States. Vernalis has exercised its co-promotion option, and the co-promotion agreement sets forth the detailed terms and conditions governing such co-promotion and amends, restates and supersedes certain sections of the license agreement. Under the terms of the co-promotion agreement, we will reimburse Vernalis for certain defined costs of their sales personnel beginning in January 2006.
5. GOODWILL AND OTHER INTANGIBLES
     Our goodwill and other intangible assets consist of the following (in thousands):
                 
    June 30,     December 31,  
    2005     2004  
Goodwill
  $ 181,079     $ 181,079  
 
           
Amortizable Intangibles:
               
Licenses
  $ 118,600     $ 123,600  
Patents
    3,200       3,200  
 
           
 
    121,800       126,800  
Less accumulated amortization
    (13,454 )     (9,542 )
 
           
Other Intangibles, net
  $ 108,346     $ 117,258  
 
           
     Goodwill and other intangibles represent a significant portion of our assets and stockholders’ equity. As of June 30, 2005, goodwill and other intangibles comprised approximately 27% of our total assets and 40% of our stockholders’ equity. SFAS No. 142, Goodwill and Other Intangible Assets (SFAS No. 142), prescribes a two-step method for determining goodwill impairment. In the first step, we determine the fair value of our one reporting unit. If the net book value of our reporting unit exceeds the fair value, we would then perform the second step of the impairment test which requires allocation of our reporting unit’s fair value to all of its assets and liabilities in a manner similar to a purchase price allocation, with any residual fair value being allocated to goodwill. An impairment charge will be recognized only when the implied fair value of our reporting unit’s goodwill is less than its carrying amount. As a result of the significance of goodwill, our results of operations and financial position in a future period could be negatively impacted should an impairment of goodwill occur.

Table of Contents

     We have one reportable segment, pharmaceutical products. Goodwill arose as a result of the August 26, 1997 acquisition of certain branded and generic pharmaceutical products, related rights and certain assets of the then DuPont Merck Pharmaceutical Company (n/k/a Bristol-Myers Squibb Pharma Company) and the July 17, 2000 acquisition of Algos. Although goodwill arose in two separate transactions, the components of our operating segment have been integrated and are managed as one reporting unit. Our components extensively share assets and other resources with the other components of our business and have similar economic characteristics. In addition, our components do not maintain discrete financial information. Accordingly, the components of our business have been aggregated into one reporting unit and are evaluated as such for goodwill impairment. Goodwill is evaluated for impairment on an annual basis on January 1st of each year unless events or circumstances indicate that an impairment may have occurred between annual dates. On January 1, 2005 and 2004, our goodwill was evaluated for impairment and, based on the fair value of our reporting unit, no impairment was identified.
     The cost of licenses are either expensed immediately or, if capitalized, are stated at cost, less accumulated amortization and are amortized using the straight-line method over their estimated useful lives ranging from eleven to twenty years. The determination to capitalize amounts related to licenses is based on management’s judgments with respect to stage of development, the nature of the rights acquired, alternative future uses, developmental and regulatory issues and challenges, the net realizable value of such amounts based on projected sales of the underlying products, the commercial status of the underlying products and/or various other competitive factors. We determine amortization periods for licenses based on our assessment of various factors impacting estimated useful lives and cash flows of the acquired rights. Such factors include the expected launch date of the product, the strength of the intellectual property protection of the product and various other competitive, developmental and regulatory issues, and contractual terms. Significant changes to any of these factors may result in a reduction in the useful life of the license and an acceleration of related amortization expense, which could cause our operating income, net income and earnings per share to decrease. The value of these licenses is subject to continuing scientific, medical and marketplace uncertainty. During the six months ended June 30, 2005, the Company expensed $20 million with respect to the acquisitions of marketing and development license rights for two products that are currently in development. We expensed the cost of these license rights based on the fact that we acquired both marketing and development rights for products that do not have regulatory approval and that do not have currently identifiable alternative future uses. As such, it was determined that the cost of the right to develop the products and the cost of the right to market the products were inextricably linked and therefore expensed in the accompanying financial statements. Patents acquired in the Algos merger are stated at cost, less accumulated amortization, and are amortized using the straight-line method over their estimated useful lives of seventeen years.
     Estimated amortization of intangibles for the five fiscal years subsequent to December 31, 2004 is as follows (in thousands):
2005   $7,826
2006   7,826
2007   7,826
2008   7,826
2009   7,826
6. NOTE RECEIVABLE
     In July 2004, we entered into a license agreement and a loan agreement with Vernalis Development Limited, or Vernalis, under which Vernalis agreed to exclusively license to us rights to market Frova® (frovatriptan) in North America. Under the loan agreement, we provided Vernalis with a loan of $50 million in August 2004. The loan was primarily used to make a payment in full and final settlement of the amounts due to Elan Corporation from Vernalis in connection with Vernalis’ reacquisition of the North American rights to Frova®. The loan is secured against the revenues receivable by Vernalis under the license agreement. At our election, we are able to offset $20 million of the $40 million MRM approval milestone and 50% of all royalties to be paid under the license agreement to Vernalis to repay the loan. To the extent not previously repaid, the loan is due in full after five years. Interest is at the rate of 5% per annum payable semi-annually. However, Vernalis has the option to defer payment of interest and increase the loan outstanding each time an interest payment becomes due. In January and July 2005, Vernalis elected to defer payment of the semi-annual interest amounts otherwise due January 31 and July 31, 2005 totaling approximately $2.4 million.

Table of Contents

     We estimated that an approximate fair market rate of interest for this type of secured loan was 8% per annum and therefore recorded the note receivable at its present value at inception of $43.8 million. The note receivable is being accreted up to its face amount at maturity using the effective interest method and thus the effective interest rate over the five year term will be 8% per annum. The difference of $6.2 million between the face amount of the note and its present value at inception has been treated as additional consideration paid to acquire the license rights and has been included in Other Intangibles.
7. COMPREHENSIVE INCOME
     Comprehensive income includes the following components for the three and six months ended June 30, 2005 and 2004 (in thousands):
                                 
    Three Months Ended     Six Months Ended

8. COMPENSATION RELATED TO STOCK OPTIONS
Endo Pharma LLC 1997 Executive and Employee Stock Option Plans and Endo Pharma LLC 2000 Supplemental Executive
and Employee Stock Option Plans
     On November 25, 1997, the Company established the 1997 Employee Stock Option Plan and the 1997 Executive Stock Option Plan (collectively, the “1997 Stock Option Plans”). On July 17, 2000, the 1997 Stock Option Plans were amended and restated. The Endo Pharma LLC 1997 Stock Option Plans are these amended and restated 1997 Stock Options Plans and reserve an aggregate of 25,615,339 shares of common stock of the Company held by Endo Pharma LLC for issuance. Stock options granted under the Endo Pharma LLC 1997 Stock Option Plans expire on August 26, 2007. Upon exercise of these stock options, only currently outstanding shares of common stock of the Company held by Endo Pharma LLC will be issued. Exercise of these stock options will not result in the issuance of additional shares in the Company and will not dilute the public stockholders. The stock options granted pursuant to the 1997 Stock Option Plans are generally exercisable upon the earlier of (i) the occurrence of a sale, disposition or transfer of Company common stock, after which neither Endo Pharma LLC nor Kelso & Company hold any shares of Company common stock or (ii) January 1, 2006 and since neither of these conditions have been met, these options are not currently exercisable.
     Pursuant to the Algos merger and related recapitalization of the Company on July 17, 2000, the Endo Pharma LLC 2000 Supplemental Stock Option Plans were established. The Endo Pharma LLC 2000 Supplemental Stock Option Plans reserve an aggregate of 10,672,314 shares of common stock of the Company held by Endo Pharma LLC for issuance. Stock options granted under the Endo Pharma LLC 2000 Supplemental Stock Option Plans expire on August 26, 2007. The Endo Pharma LLC 2000 Supplemental Stock Option Plans became effective on January 1, 2003, resulting in the issuance of 10,672,314 stock options to certain employees and members of management. No additional shares of Company common stock will be issued, however, because these stock options are exercisable only into shares of Company common stock that are held by Endo Pharma LLC. Accordingly, exercise of these stock options will not result in the issuance of additional shares in the Company and will not dilute the public stockholders.
     The shares of Company common stock that individuals receive upon exercise of stock options pursuant to the Endo Pharma LLC 1997 Stock Option Plans and the Endo Pharma LLC 2000 Supplemental Stock Option Plans are currently subject to significant restrictions that are set forth in stockholders’ agreements.

Table of Contents

     The Class C Endo Pharma LLC stock options (all of which are vested) become exercisable at the earlier of an exit event, as defined, or January 1, 2006. If the Class C stock options are not exercised by January 1, 2006, they would terminate. Although the Company has considered extending the term of the Class C stock options, following enactment of the 2004 Jobs Creation Act, an extension of the term of the stock options would result in adverse tax consequences for the option holders. As a result, the Company and Endo Pharma LLC are reviewing several alternatives which would allow approximately 22 million Class C stock options to be exercised before their expiration on January 1, 2006. Holders of stock options granted under the Endo Pharma LLC Stock Option Plans and shares of Company common stock received by such holders upon exercise of the options are bound by transfer restrictions pursuant to stockholders agreements. These transfer restrictions may be waived by Endo Pharma LLC at any time. The Company expects that Endo Pharma LLC will waive the transfer restrictions on a portion of the shares of Company common stock received by exercising option holders from Endo Pharma LLC at the time of exercise and that holders may sell a portion of the shares they receive upon exercise in an amount sufficient to satisfy such holders’ related tax and exercise price obligations. Alternatively, a portion of the shares of Company common stock to be received by option holders from Endo Pharma LLC upon exercise may be withheld to satisfy such holders’ related tax and exercise price obligations, and the Company’s tax withholding obligations in connection with such exercise, with the Company being required to satisfy such obligations in cash. The exercise of the Class C stock options is expected to generate a significant tax deduction for the Company and create a significant tax sharing payment obligation to Endo Pharma LLC pursuant to the tax sharing agreement. Upon exercise, option holders will receive shares of Company common stock currently owned by Endo Pharma LLC. Accordingly, no shares of Company common stock will be issued upon exercise of the Class C stock options.
Endo Pharmaceuticals Holdings Inc. 2000 and 2004 Stock Incentive Plans
     On August 11, 2000, we established the 2000 Stock Incentive Plan. The 2000 Stock Incentive Plan reserves an aggregate of 4,000,000 shares of common stock of the Company for issuance to employees, officers, directors and consultants. The 2000 Stock Incentive Plan provides for the issuance of stock options, restricted stock, stock bonus awards, stock appreciation rights or performance awards. In May 2004, our stockholders approved the Endo Pharmaceuticals Holdings Inc. 2004 Stock Incentive Plan. The maximum number of shares of Company stock reserved for issuance under the 2004 Plan is 4,000,000 shares. The 2004 Plan provides for the grant of stock options, stock appreciation rights, shares of restricted stock, performance shares, performance units or other share-based awards that may be granted to executive officers and other employees of the Company, including officers and directors who are employees, to non-employee directors and to consultants to the Company. As of December 31, 2004, only stock options have been awarded under both plans. Stock options granted under the 2000 and 2004 Stock Incentive Plans generally vest over four years and expire ten years from the date of grant. Unlike the stock options granted under the Endo Pharma LLC Stock Option Plans, the exercise of the stock options granted pursuant to the Endo Pharmaceuticals Holdings Inc. 2000 and 2004 Stock Incentive Plans will dilute our public stockholders. During the three and six months ended June 30, 2005, 259,966 and 325,795 stock options were granted pursuant to these plans, respectively.
Stock-Based Compensation
     The Company accounts for its stock-based employee compensation plan under the intrinsic value method in accordance with Accounting Principles Board Opinion (“APB”) No. 25, Accounting for Stock Issued to Employees, and related Interpretations. The Company has adopted the disclosure-only provisions of SFAS No. 123, Accounting for Stock-Based Compensation, as amended by SFAS No. 148, Accounting for Stock-Based Compensation — Transition and Disclosure.
     Pro-forma information regarding net income and earnings per share, as presented below, is required by SFAS No. 123, as amended by SFAS No. 148, and has been determined as if the Company had accounted for its employee stock options under the fair value method of SFAS No. 123 as of its effective date. We estimated the fair value of our stock options, as of the respective date of grant, using a Black-Scholes option-pricing model. The following weighted average assumptions were used for such estimates: no dividend yield; expected volatility of 58% in 2005 and 70% in 2004; risk-free interest rate of 3.7% and 3.2% for 2005 and 2004, respectively; and a weighted average expected life of the options of 5 years. Had the Company elected to adopt the fair value recognition provisions of SFAS No. 123, pro forma net income and net income per share would be as follows (in thousands, except per share data):
                                 
    Three Months Ended     Six Months Ended

9. RELATED PARTY TRANSACTIONS
     Tax Sharing Agreement. On July 14, 2000, Endo Pharma LLC was formed in connection with the Algos merger to ensure that the stock options granted pursuant to the Endo Pharma LLC Stock Option Plans diluted only the Endo common stock held by persons and entities that held such shares prior to our merger with Algos. Endo Pharma LLC is a limited liability company that currently holds a significant portion of our common stock, in which affiliates of Kelso & Company and certain members of management have an interest. Upon the exercise of these stock options, only currently outstanding shares of our common stock held by Endo Pharma LLC will be delivered. Because Endo Pharma LLC, and not us, will provide the shares upon the exercise of these options, we have entered into a tax sharing agreement with Endo Pharma LLC under which we are required to pay to Endo Pharma LLC the amount of the tax benefits usable by us as a result of the exercise of these stock options into shares of our common stock held by Endo Pharma LLC. As of June 30, 2005, approximately 10.6 million of these stock options had been exercised into shares of our common stock held by Endo Pharma LLC. Upon exercise of any of these Endo Pharma LLC stock options, we generally will be permitted to deduct as a compensation charge, for federal income tax purposes, an amount equal to the difference between the market price of our common stock and the exercise price paid upon exercise of these options (as of June 30, 2005, approximately $149 million), which is estimated to result in a tax benefit amount of approximately $57 million. Under the tax sharing agreement, we are required to pay this $57 million to Endo Pharma LLC to the extent that a compensation charge deduction is usable by us to reduce our taxes and based upon the assumption that all other deductions of Endo are used prior thereto.
     Using a weighted average exercise price of $2.60 per share and an assumed effective tax rate of 38.3%, if all 36.3 million stock options under the Endo Pharma LLC Stock Option Plans were vested and exercised (including the 10.6 million stock options already exercised as discussed above):
    upon exercise, assuming the market price of our common stock is then $20.00 per share, we generally would be able to deduct, for federal income tax purposes, compensation of approximately $632 million, which could result in a tax benefit amount of approximately $242 million payable to Endo Pharma LLC.
 
    upon exercise, assuming the market price of our common stock is then $25.00 per share, we generally would be able to deduct, for federal income tax purposes, compensation of approximately $813 million, which could result in a tax benefit amount of approximately $311 million payable to Endo Pharma LLC.
 
    upon exercise, assuming the market price of our common stock is then $30.00 per share, we generally would be able to deduct, for federal income tax purposes, compensation of approximately $994 million, which could result in a tax benefit amount of approximately $381 million payable to Endo Pharma LLC.

Table of Contents

     On April 30, 2004, the tax sharing agreement was amended to provide for a specific schedule upon which payments currently contemplated by the tax sharing agreement would be made. The amended tax sharing agreement provides that the amount of the tax benefits usable by us in each such year will be paid to Endo Pharma LLC in two installments: (i) 50% of the estimated amount shall be paid within 15 business days of our receipt from our independent registered public accounting firm of an opinion on our final audited financial statements, and (ii) the remaining amount shall be paid within 30 business days of the filing of our federal income tax return.
     In 2004, we paid $13.5 million to Endo Pharma LLC to satisfy the tax sharing obligations attributable to 2001, 2002 and 2003. Since 3.8 million shares underlying stock options granted under the Endo Pharma LLC stock option plans were exercised into common stock and sold in the offering on August 9, 2004, at a price of $17.46, with a weighted average exercise price of $2.44, an assumed tax rate of 38.3% and assuming the attributable compensation charge deductions are usable to reduce our taxes related to 2004, we are obligated to pay Endo Pharma LLC a tax benefit of approximately $22 million. In addition, since 2.8 million shares underlying stock options granted under the Endo Pharma LLC stock option plans were exercised into common stock and sold in the offering on November 29, 2004, at a price of $20.02, with a weighted average exercise price of $2.44, an assumed tax rate of 38.3% and assuming the attributable compensation charge deductions are usable to reduce our taxes related to 2004, we are obligated to pay Endo Pharma LLC a tax benefit of approximately $19 million. Fifty percent of the tax benefit amount attributable to these two 2004 offerings and other Endo Pharma LLC stock option exercises in 2004, aggregating $21.4 million, was due and was paid within 15 business days of the date we received an opinion on our audited 2004 financial statements from our independent registered public accounting firm and the remaining fifty percent of the tax benefit amount attributable to 2004 is due within 30 business days of the date on which we file our 2004 tax return with the Internal Revenue Service (which we estimate will occur in September 2005). As of June 30, 2005, approximately $22.2 million is payable to Endo Pharma LLC related to estimated tax sharing payments that we are obligated to pay which are attributable to 2004 and 2005. All payments made and accrued pursuant to the tax sharing agreement have been reflected as a reduction of stockholders’ equity in the accompanying financial statements. The estimated tax benefit amount payment to Endo Pharma LLC attributable to Endo Pharma LLC stock options exercised may increase if certain holders of Endo Pharma LLC stock options exercise additional stock options in the future.
     On April 30, 2004, we filed a shelf registration statement on Form S-3, as amended on June 10, June 14 and June 25, 2004, providing for the sale by Endo Pharma LLC and certain other selling stockholders named therein, including certain of our directors and officers, from time to time, of up to 30 million currently issued and outstanding shares of our common stock. The shelf registration statement was declared effective by the Securities and Exchange Commission on June 28, 2004. After the closing of the August 9 and November 29, 2004 offerings, which totaled 19 million shares, up to 11 million shares remain eligible for sale by Endo Pharma LLC under this shelf registration statement. The shelf registration statement enables one or more offerings of common stock, subject to market conditions. The nature and terms of any offering will be established at the time of the offering and set forth in a prospectus supplement. Any offering would most likely trigger an additional tax sharing payment to Endo Pharma LLC, would not increase the number of our outstanding shares of common stock and we would not receive any proceeds from any offering covered by this shelf registration. Endo Pharma LLC has informed us that, subject to a variety of factors, including market conditions and stock price levels, it may initiate additional secondary offerings of our common stock in the future.
     The Class C Endo Pharma LLC stock options (all of which are vested) become exercisable at the earlier of an exit event, as defined, or January 1, 2006. If the Class C stock options are not exercised by January 1, 2006, they would terminate. Although the Company has considered extending the term of the Class C stock options, following enactment of the 2004 Jobs Creation Act, an extension of the term of the stock options would result in adverse tax consequences for the option holders. As a result, the Company and Endo Pharma LLC are reviewing several alternatives which would allow approximately 22 million Class C stock options to be exercised before their expiration on January 1, 2006. Holders of stock options granted under the Endo Pharma LLC Stock Option

Plans and shares of Company common stock received by such holders upon exercise of the options are bound by transfer restrictions pursuant to stockholders agreements. These transfer restrictions may be waived by Endo Pharma LLC at any time. The Company expects that Endo Pharma LLC will waive the transfer restrictions on a portion of the shares of Company common stock received by exercising option holders from Endo Pharma LLC at the time of exercise and that holders may sell a portion of the shares they receive upon exercise in an amount sufficient to satisfy such holders’ related tax and exercise price obligations. Alternatively, a portion of the shares of Company common stock to be received by option holders from Endo Pharma LLC upon exercise may be withheld to satisfy such holders’ related tax and exercise price obligations, and the Company’s tax withholding obligations in connection with such exercise, with the Company being required to satisfy such obligations in cash. The exercise of the Class C stock options is expected to generate a significant tax deduction for the Company and create a significant tax sharing payment obligation to Endo Pharma LLC pursuant to the tax sharing agreement. Upon exercise, option holders will receive shares of Company common stock currently owned by Endo Pharma LLC. Accordingly, no shares of Company common stock will be issued upon exercise of the Class C stock options.
     Settlement of Contingent Obligation. During the six months ended June 30, 2005, the Company reached a tentative agreement with an individual to compensate him a total of $2 million for past services rendered to the Company. This agreement was finalized on May 10, 2005, and the $2 million has been recorded in selling, general and administrative expenses during the six months ended June 30, 2005. It is anticipated that Endo Pharma LLC will make these payments totaling $2 million on behalf of the Company, and they will be treated as a capital contribution by Endo Pharma LLC once payments are made. Endo Pharma LLC made a payment of $800,000, pursuant to the settlement agreement, on behalf of the Company in May 2005 and this payment has been treated as a capital contribution in the accompanying financial statements. The remaining obligation pursuant to this agreement is $1.2 million as of June 30, 2005.
10. COMMITMENTS AND CONTINGENCIES
License Agreements, Milestones and Royalties
     Hind Healthcare Inc.
     Under the terms of the Hind License Agreement, royalties are recorded as a reduction to net sales due to the nature of the license agreement and the characteristics of the license involvement by Hind in Lidoderm®. The royalty rate is 10% of net sales through the shorter of (1) the expiration of the last licensed patent or (2) November 20, 2011, including a minimum royalty of at least $500,000 per year. During the three months ended June 30, 2005 and 2004, we accrued $11.1 million and $6.5 million for these royalties to Hind, respectively, which were recorded as a reduction to net sales. During the six months ended June 30, 2005 and 2004, we accrued $18.2 million and $13.8 million for these royalties to Hind, respectively.
     Penwest Pharmaceuticals
     Under the terms of the amended and restated strategic alliance agreement with Penwest Pharmaceuticals Co. (Penwest), Penwest is entitled to receive royalties equal to a percentage beginning at 50%, which could decline to 40% based upon the achievement of certain criteria, of the net realization (as defined in the agreement) of oxymorphone ER. On March 18, 2003, we received notice from Penwest that it was exercising its right under the agreement to cease funding its share of the development and pre-launch marketing costs of this product on account of its concern about its ability to access external capital funding opportunities in the future. Accordingly, we are now responsible for funding 100% of these remaining costs until oxymorphone ER is approved by the FDA, at which time we will recoup from the royalties due to Penwest the full amount of what Penwest should have contributed had it not exercised such right.
     Lavipharm
     In November 1999, Endo entered into a collaboration agreement with Lavipharm Laboratories, Inc. pursuant to which Endo obtained exclusive worldwide rights to Lavipharm’s existing drug delivery technology platforms. Under the terms of this collaboration agreement, Endo paid an upfront license fee of $1 million. In September 2001, we amended this agreement to limit its scope to one of Lavipharm’s existing drug delivery technologies in combination with two specific active drug substances. In January 2004, we terminated this agreement and made a termination payment to Lavipharm of $3 million plus the potential for up to an additional $5 million upon the occurrence of future events. We wrote-off the unamortized portion of the upfront license fee and expensed the termination payment of $3 million during the six months ended June 30, 2004.

     DURECT Corporation
     Once a specified clinical trial of CHRONOGESIC™ is started or beginning on January 1, 2006 (whichever is earlier), unless the agreement is earlier terminated, Endo will be obligated to fund 50% of the ongoing development costs of CHRONOGESIC™. Endo will also reimburse DURECT for a portion of its prior development costs upon the achievement of certain milestones. Milestone payments made by Endo under the License Agreement could total up to $52.0 million. Endo and DURECT will share profits equally, based on projected financial performance of CHRONOGESIC™. In addition, the DURECT CHRONOGESIC™ agreement also contains terms and conditions customary for this type of arrangement, including representations, warranties, indemnities and termination rights. With respect to termination rights, this agreement permits Endo to terminate its continued participation under a number of circumstances, one of which could require Endo to pay DURECT $10.0 million.
     On March 14, 2005, we announced that we signed an agreement that gives us the exclusive license to develop and commercialize DURECT’s sufentanil-containing transdermal patch in the U.S. and Canada (the “DURECT Sufentanil Agreement”). The sufentanil patch, which is in early-stage clinical development, employs DURECT’s proprietary TRANSDUR™ drug-adhesive matrix formulation and is intended to provide relief of moderate-to-severe chronic pain for up to seven days. We have assumed all remaining development and regulatory filing responsibility for this product, including the funding thereof. Under the terms of the DURECT Sufentanil Agreement, in April 2005, we paid DURECT a $10 million upfront fee, which was expensed as research and development in the first quarter of 2005, with additional payments of approximately $35 million upon achievement of predetermined regulatory and commercial milestones. We will also pay royalties to DURECT on net sales of the sufentanil transdermal patch. In addition, the DURECT Sufentanil Agreement also contains terms and conditions customary for this type of arrangement, including representations, warranties, indemnities and termination rights. The DURECT Sufentanil Agreement will continue in effect until terminated. The DURECT Sufentanil Agreement provides each party with specified termination rights, including the right of each party to terminate the DURECT Sufentanil Agreement upon material breach of the DURECT Sufentanil Agreement by the other party and the right of Endo to terminate the DURECT Sufentanil Agreement at any time without cause subject to a specified notice period.
     SkyePharma, Inc.
     Under the terms of our agreement with SkyePharma, we are required to pay to SkyePharma a share of each product’s sales revenue, which share may increase from 20% initially, to a maximum of 60%, of net sales as the products’ combined sales achieve certain thresholds. In addition, future milestone payments may be due SkyePharma as follows (in thousands):
         
    Milestone  
Milestone Event   Payment  
The first time net sales of DepoDur™ in a calendar year exceed $125,000
  $ 15,000

    40,000  
 
     
Total contingent regulatory milestones for Propofol IDD-D™
  $ 45,000  
 
     
     In addition, this agreement also contains terms and conditions customary for this type of arrangement, including representations, warranties, indemnities and termination rights. This agreement generally lasts until the underlying patents on the product expire. With respect to termination rights, this agreement permits Endo to terminate its continued participation under a number of circumstances, one of which could require us to pay SkyePharma $5.0 million.

     Noven Pharmaceuticals, Inc.
     Under the terms of our license agreement with Noven, upon our first commercial sale of the fentanyl patch, Noven is entitled to receive an additional payment ranging from $5.0 million to $10.0 million, depending on the timing of launch and the number of generic competitors on the market. The profit on the product will be shared. This license agreement also establishes an ongoing collaboration between the two companies to identify and develop additional new transdermal therapies. As part of this effort, Noven will undertake feasibility studies to determine whether certain compounds identified by the parties can be delivered through Noven’s transdermal patch technology. Endo is expected to fund and manage clinical development of those compounds proceeding into clinical trials. Additionally, we are bearing a portion of the risk of loss related to inventory costs associated with the fentanyl patch that have been incurred by us and by Noven. If final regulatory approval of the product is denied or delayed, our risk of loss is approximately $5 million. No amounts have been expensed as of June 30, 2005 related to our risk of loss based upon our judgment of probable future commercial use.
     On July 14, 2005, the FDA issued a public advisory that it is investigating reports of death and other serious side effects from overdoses involving both the branded and generic fentanyl patches, and we are aware that the FDA is considering such safety issues in their review of pending fentanyl patch ANDAs. The FDA has indicated that it will provide public updates as new information regarding the investigation becomes available. We are unable to predict the outcome or impact of this investigation. It could, however, materially and adversely affect the market for all fentanyl patch products, and could delay or prevent approval of pending ANDAs for fentanyl, including our pending application.
     EpiCept Corp.
     Our license agreement with EpiCept provides for Endo to pay EpiCept milestones as well as royalties on the net sales of EpiCept’s LidoPAIN® BP product. EpiCept has also retained an option to co-promote the LidoPAIN® BP product. Under this agreement, Endo also received an exclusive, worldwide license to certain patents of EpiCept Corp. Milestone payments made by Endo under this agreement, including regulatory milestones and sales thresholds, could total up to $82.5 million.
     Vernalis Development Limited
     Under the terms of our license agreement with Vernalis, we will make anniversary payments for the first two years of $15 million in 2005 and 2006, and a $40 million milestone payment upon FDA approval for the menstrually related migraine indication. In addition, Vernalis will receive one-time milestone payments for achieving defined annual net sales targets. These sales milestone payments increase based on increasing net sales targets ranging from a milestone of $10 million on $200 million in net sales to a milestone of $75 million on $1.2 billion in net sales. These sales milestones could total up to $255 million if all of the defined net sales targets are achieved. We will also pay royalties to Vernalis based on the net sales of Frova®.
     Orexo AB
     Our agreement with Orexo provides for us to make additional license fees and payments based on development and regulatory milestones, which may total up to $22.1 million through FDA approval of Rapinyl™’s New Drug Application. The agreement also provides for royalties upon commercial sales and may include sales milestones, up to $39.2 million, if defined sales thresholds are achieved. In addition, the license agreement also contains customary terms and conditions, including representations, warranties, indemnities and termination rights. The term of the license agreement shall be until the later of (i) the expiration of the patents or (ii) the expiration of any market exclusivity right. We can terminate the license agreement under certain circumstances, including upon six months’ written notice, and we may be required to pay a termination fee of up to $1.5 million.

     ProEthic Pharmaceuticals, Inc.
     On March 14, 2005, we entered into an agreement with ProEthic Pharmaceuticals, Inc. for the U.S. and Canadian rights to develop and commercialize a once-daily ketoprofen-containing topical patch. Ketoprofen is a non-steroidal anti-inflammatory drug (NSAID) generally used for the treatment of inflammation and pain and currently available in the U.S. only in oral form. Currently in Phase II clinical trials in the U.S., the ketoprofen patch is being developed for the localized treatment of acute pain associated with soft-tissue injuries such as tendonitis or joint sprains and strains. Two Phase III placebo-controlled studies in soft-tissue injury and ankle sprains have been completed in Europe by ProEthic’s European partner APR Applied Pharma Research AG, with statistically significant results. Under the terms of the agreement, in March 2005, we made a $10 million upfront payment, which was expensed as research and development in the first quarter of 2005, and we could be required to make additional payments of approximately $13.0 million for the achievement of certain regulatory and other milestones. We will also pay royalties on net sales of the ketoprofen patch. In addition, the license agreement also contains customary terms and conditions, including representations, warranties, indemnities and termination rights. The term of this license agreement shall be until the later of (i) the expiration of the patents or (ii) the tenth (10th) anniversary of the date of the first commercial sale of the product. We can terminate the agreement at any time upon no more than ninety (90) days’ written notice.
     Life Sciences Opportunities Fund (Institutional) II, L.P.
     On December 12, 2003, we entered into a subscription agreement to invest up to $10 million into Life Sciences Opportunities Fund (Institutional) II, L.P., a Delaware limited partnership formed to carry out investments in life science companies. As part of this investment, we are able to capitalize on the knowledge of LOF Partners, LLC, the general partner, and its access to, life sciences entities with promising pharmaceutical assets, technologies and management talent and on the general partner’s wide range of industry contacts and resources. As of June 30, 2005, we have invested $1 million in this partnership and are accounting for this investment utilizing the equity method. In July 2005, the partnership made a capital call of approximately $1.7 million, which we invested in the third quarter of 2005.
     Employment Agreements
     We have entered into employment agreements with certain members of management.
     Research Contracts
     We routinely contract with universities, medical centers, contract research organizations and other institutions for the conduct of research and clinical studies on our behalf. These agreements are generally for the duration of the contracted study and contain provisions that allow us to terminate prior to completion.
     Collaboration Agreements
     We have also entered into certain other collaboration agreements with third parties for the development of pain management products. Potential milestone payments pursuant to these contracts could total up to $61 million. These agreements require us to share in the development costs of such products and grant marketing rights to us for such products. If our third party partners are unable or unwilling to fund their portion of the collaboration project with us, this may adversely affect our results of operations and cash flows in the foreseeable future.

     Legal Proceedings
     While we cannot predict the outcome of the following legal proceedings, we believe that the claims against us are without merit, and we intend to vigorously defend our position. An adverse outcome in any of these proceedings could have a material adverse effect on our current and future financial position and results of operations. No amounts have been accrued with respect to any of these unsettled legal proceedings at June 30, 2005.
     Purdue Pharma L.P., et al. v. Endo Pharmaceuticals Inc., et al., Index No. 00 Civ. 8029 (SHS) (S.D.N.Y.); Purdue Pharma L.P., et al. v. Endo Pharmaceuticals Inc., et al., Index No. 01 Civ. 2109 (SHS) (S.D.N.Y.); Purdue Pharma L.P., et al. v. Endo Pharmaceuticals Inc., et al., Index No. 01 Civ. 8177 (SHS) (S.D.N.Y.)
     On October 20, 2000, The Purdue Frederick Company and related companies (Purdue Frederick) filed suit against us and our subsidiary, Endo Pharmaceuticals Inc. (EPI), in the U.S. District Court for the Southern District of New York alleging that EPI’s bioequivalent version of Purdue Frederick’s OxyContin® (oxycodone hydrochloride extended-release tablets), 40mg strength, infringes three of its patents. This suit arose after EPI provided the plaintiffs with notice that its ANDA submission for a bioequivalent version of Purdue Frederick’s OxyContin®, 40mg strength, challenged the listed patents for OxyContin® 40mg tablets. On March 13, 2001, Purdue Frederick filed a second suit against us and EPI in the U.S. District Court for the Southern District of New York alleging that EPI’s bioequivalent versions of Purdue Frederick’s OxyContin®, 10mg and 20mg strengths, infringe the same three patents. This suit arose from EPI having amended its earlier ANDA on February 9, 2001 to add bioequivalent versions of the 10mg and 20mg strengths of OxyContin®. On August 30, 2001, Purdue Frederick filed a third suit against us and EPI in the U.S. District Court for the Southern District of New York alleging that EPI’s bioequivalent version of Purdue Frederick’s OxyContin®, 80mg strength, infringes the same three patents. This suit arose from EPI having amended its earlier ANDA on July 30, 2001 to add the bioequivalent version of the 80mg strength of OxyContin®.
     For each of the 10mg, 20mg, 40mg and 80mg strengths of this product, EPI made the required Paragraph IV certification against the patents listed in the FDA’s Orange Book as covering these strengths of OxyContin®. EPI pleaded counterclaims that the patents asserted by Purdue Frederick are invalid, unenforceable and/or not infringed by EPI’s formulation of oxycodone hydrochloride extended-release tablets, 10mg, 20mg, 40mg and 80mg strengths. EPI also counterclaimed for antitrust damages based on allegations that Purdue Frederick obtained the patents through fraud on the United States Patent and Trademark Office and is asserting them while aware of their invalidity and unenforceability.
     The trial of the patent claims in all three of the suits against us and EPI concluded on June 23, 2003. On January 5, 2004, the district court issued an opinion and order holding that, while Endo infringes the three Purdue patents, the patents are unenforceable due to inequitable conduct. The district court, therefore, dismissed the patent claims against us and EPI, declared the patents invalid, and enjoined Purdue from further enforcement of the patents. Purdue filed an appeal, as well as motions to expedite the appeal and to stay the injunction against enforcement of the patents until the appeal is resolved. Both motions were denied on March 18, 2004. In turn, we have cross-appealed the district court’s infringement ruling. Briefing on the appeal and cross-appeal concluded in July 2004. By an earlier order, the judge bifurcated the antitrust counterclaims for a separate and subsequent trial. On November 3, 2004, the oral arguments relating to the appeal of this case were heard by the U.S. Court of Appeals for the Federal Circuit in Washington, D.C., at which hearing both sides presented their arguments before a three-judge panel. On June 7, 2005, we announced that the U.S. Court of Appeals for the Federal Circuit in Washington, D.C., had affirmed the Opinion and Order issued in Endo’s favor by the U.S. District Court for the Southern District of New York on January 5, 2004. This affirmance by the Federal Circuit Court dismisses the claims that Endo’s oxycodone extended-release tablets, 10mg, 20mg, 40mg, and 80mg, a bioequivalent version of Purdue Frederick’s OxyContin®, infringe Purdue’s U.S. Patent Nos. 5,549,912, 5,508,042 and 5,656,295, and permanently enjoins Purdue from enforcing these patents. On June 21, 2005, Purdue filed a petition with the Federal Circuit seeking rehearing of the case by the panel that issued the June 7, 2005 decision, or alternatively by the entire court. On July 22, 2005, the Federal Circuit Court of Appeals requested that Endo submit a response brief as part of its review process of Purdue’s petition for rehearing and rehearing en banc. Endo submitted this response on August 1, 2005. The Company remains confident that the prior decision of the Federal Circuit Court will remain in effect and intends to continue to pursue its antitrust claims against Purdue.
     Litigation similar to that described above may also result from products we currently have in development, as well as those that we may develop in the future. We, however, cannot predict the timing or outcome of any such litigation, or whether any such litigation will be brought against us.

     Linda Serafin, et al. v. Purdue Pharma L.P., et al., No. 103031/04 (Supreme Court of the State of New York, County of New York)
     On February 27, 2004, EPI was named, along with three other pharmaceutical companies, a hospital, and a doctor, as a defendant in a lawsuit filed by Linda Serafin and Michael Serafin in the Supreme Court of the State of New York, County of New York. According to the complaint, each of the pharmaceutical companies manufactured or distributed the drugs oxycodone and OxyContin®. The complaint alleges that EPI and another defendant manufactured oxycodone, OxyContin® and/or Percocet®. The complaint alleges that the defendants failed to adequately warn about the dangers involved with these drugs and that as a result of this failure to warn, plaintiffs sustained injury. EPI intends to defend itself vigorously in this case.
     Litigation similar to that described above may also be brought by other plaintiffs in other jurisdictions. However, we cannot predict the timing or outcome of any such litigation, or whether any such litigation will be brought against us.
     Pricing Litigation
     A number of cases, brought by local and state government entities, are pending that allege generally that EPI and numerous other pharmaceutical companies reported false pricing information in connection with certain drugs that are reimbursable under Medicaid. These cases generally seek damages, treble damages, disgorgement of profits, restitution and attorneys’ fees. The federal court cases have been or are in the process of being consolidated in the United States District Court for the District of Massachusetts under the Multidistrict Litigation Rules as In re: Pharmaceutical Industry Average Wholesale Price Litigation, MDL 1456. The following previously reported cases have been consolidated into one consolidated complaint in MDL 1456: City of New York v. Abbott Laboratories, Inc., et al.; County of Albany v. Abbott Laboratories, Inc., et al.; County of Allegany v. Abbott Laboratories, Inc., et al.; County of Broome v. Abbott Laboratories, Inc., et al.; County of Cattaraugus v. Abbott Laboratories, Inc., et al; County of Cayuga v. Abbott Laboratories, Inc., et al.; County of Chautauqua v. Abbott Laboratories, Inc., et al.; County of Chenango v. Abbott Laboratories, Inc., et al.; County of Fulton v. Abbott Laboratories, Inc., et al.; County of Genesee v. Abbott Laboratories, Inc., et al.; County of Greene v. Abbott Laboratories, Inc., et al.; County of Herkimer v. Abbott Laboratories, Inc., et al.; County of Monroe v. Abbott Laboratories, Inc., et al.; County of Oneida v.

Abbott Laboratories, Inc., et al.; County of Washington v. Abbott Laboratories, Inc., et al.; County of Wayne v. Abbott Laboratories, Inc., et al.; County of Westchester v. Abbott Laboratories, Inc., et al; and County of Yates v. Abbott Laboratories, Inc., et al. Four previously unreported federal cases have been filed against EPI and numerous other pharmaceutical companies and have been consolidated with the cases listed above in the consolidated complaint in MDL 1456. Those cases are: County of Jefferson v. Abbott Laboratories, Inc., et al., filed in June 2005 in the United States District Court for the Northern District of New York; County of Madison v. Abbott Laboratories, Inc., et al., filed in June 2005 in the United States District Court for the Northern District of New York; County of Niagra v. Abbott Laboratories, Inc., et al., filed in June 2005 in the United States District Court for the Western District of New York; and County of Putnam v. Abbott Laboratories, Inc., et al., filed in May 2005 in the United States District Court for the Southern District of New York. Nine new federal cases naming EPI in addition to numerous other pharmaceutical companies have been filed under seal. These cases will likely be transferred to MDL 1456 and consolidated into the consolidated complaint in MDL 1456 with the other cases listed above. The nine new cases are: County of Columbia v. Abbott Laboratories, Inc., et al., filed in July 2005 in the United States District Court for the Northern District of New York; County of Cortland v. Abbott Laboratories, Inc., et al., filed in July 2005 in the United States District Court for the Northern District of New York; County of Dutchess v. Abbott Laboratories, Inc., et al., filed in July 2005 in the United States District Court for the Southern District of New York; County of Essex v. Abbott Laboratories, Inc., et al., filed in July 2005 in the United States District Court for the Northern District of New York; County of Lewis v. Abbott Laboratories, Inc., et al., filed in July 2005 in the United States District Court for the Northern District of New York; County of Ontario v. Abbott Laboratories, Inc., et al., filed in July 2005 in the United States District Court for the Western District of New York; County of Orleans v. Abbott Laboratories, Inc., et al., filed in July 2005 in the United States District Court for the Western District of New York; County of Schuyler v. Abbott Laboratories, Inc., et al., filed in July 2005 in the United States District Court for the Western District of New York; and County of Seneca v. Abbott Laboratories, Inc., et al., filed in July 2005 in the United States District Court for the Western District of New York. One previously reported case filed in state court and removed to federal court is in the process of being transferred to MDL 1456: County of Erie v. Abbott Laboratories, Inc., et al.

     There is also a similar case pending in federal court in Alabama against EPI and numerous other pharmaceutical companies: State of Alabama v. Abbott Laboratories, Inc., et al., filed in January 2005 in the Circuit Court of Montgomery County, Alabama and removed to the United States District Court for the Middle District of Alabama on July 13, 2005. This case is in the process of being transferred to MDL 1456.
     The Company intends to contest all of these cases vigorously. Litigation similar to that described above may also be brought by other plaintiffs in various jurisdictions. However, we cannot predict the timing or outcome of any such litigation, or whether any such litigation will be brought against the Company.
Other Legal Proceedings
     In addition to the above proceedings, we are involved in, or have been involved in, arbitrations or various other legal proceedings that arise from the normal course of our business. We cannot predict the timing or outcome of these claims and other proceedings. Currently, we are not involved in any arbitration and/or other legal proceeding that we expect to have a material effect on our business, financial condition, results of operations or cash flows.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations.
     Except for the historical information contained in this Report, this Report, including the following discussion, contains forward-looking statements that involve risks and uncertainties. See “Forward-Looking Statements” beginning on page 3 of this Report.
Overview
     We, through our wholly owned subsidiary, Endo Pharmaceuticals Inc., are engaged in the research, development, sales and marketing of branded and generic prescription pharmaceuticals used primarily for the treatment and management of pain. Branded products comprised approximately 70%, 69% and 72% of net sales for the years ended December 31, 2003 and 2004 and the six months ended June 30, 2005. On August 26, 1997, an affiliate of Kelso & Company and the then members of management entered into an asset purchase agreement with the then DuPont Merck Pharmaceutical Company to acquire certain branded and generic pharmaceutical products and exclusive worldwide rights to a number of new chemical entities in the DuPont research and development pipeline from DuPont Merck through the newly-formed Endo Pharmaceuticals Inc. The stock of Endo Pharmaceuticals Inc. is our only asset, and we have no other operations or business.
     On March 9, 2005, we announced that Peter A. Lankau, the then current president and chief operating officer of Endo, had been appointed president and chief executive officer by our Board of Directors, effective May 20, 2005, the day following the Annual Meeting of Endo Stockholders. Carol A. Ammon, Endo’s former chief executive officer, will continue to serve Endo as Chairman of the Board of Directors. In addition, Endo’s Board of Directors had appointed Lankau to the Endo Board of Directors, effective March 9, 2005. This appointment expanded the number of directors to 11.

     On March 14, 2005, we announced that we signed an agreement that gives us the exclusive license to develop and commercialize DURECT’s sufentanil-containing transdermal patch in the U.S. and Canada (the “DURECT Sufentanil Agreement”). The sufentanil patch, which is in early-stage clinical development, employs DURECT’s proprietary TRANSDUR™ drug-adhesive matrix formulation and is intended to provide relief of moderate-to-severe chronic pain for up to seven days. We have assumed all remaining development and regulatory filing responsibility for this product, including the funding thereof. Under the terms of the DURECT Sufentanil Agreement, in April 2005, we paid DURECT a $10 million upfront fee, with additional payments of approximately $35 million upon achievement of predetermined regulatory and commercial milestones. We will also pay royalties to DURECT on net sales of the sufentanil transdermal patch.
     Also on March 14, 2005, we announced that we entered into an agreement with ProEthic Pharmaceuticals, Inc. for the U.S. and Canadian rights to develop and commercialize a once-daily ketoprofen-containing topical patch. Ketoprofen is a non-steroidal anti-inflammatory drug (NSAID) generally used for the treatment of inflammation and pain and currently available in the U.S. only in oral form. Currently in Phase II clinical trials in the U.S., the ketoprofen patch is being developed for the localized treatment of acute pain associated with soft-tissue injuries such as tendonitis or joint sprains and strains. Two Phase III placebo-controlled studies in soft-tissue injury and ankle sprains have been completed in Europe by ProEthic’s European partner APR Applied Pharma Research AG, with statistically significant results. Under the terms of the agreement, in March 2005, we made a $10 million upfront payment and could be required to make additional payments of approximately $13.0 million for the achievement of certain regulatory and other milestones. We will also pay royalties on net sales of the ketoprofen patch.
     On June 7, 2005, we announced that the U.S. Court of Appeals for the Federal Circuit in Washington, D.C., had affirmed the Opinion and Order issued in Endo’s favor by the U.S. District Court for the Southern District of New York on January 5, 2004. This affirmance by the Federal Circuit Court dismissed the claims that Endo’s oxycodone extended-release tablets, 10mg, 20mg, 40mg, and 80mg, a bioequivalent version of Purdue Frederick’s OxyContin®, infringe Purdue’s U.S. Patent Nos. 5,549,912, 5,508,042 and 5,656,295, and permanently enjoins Purdue from enforcing these patents. On June 21, 2005, Purdue filed a petition with the Federal Circuit seeking rehearing of the case by the panel that issued the June 7, 2005 decision, or alternatively by the entire court. On July 22, 2005, the Federal Circuit Court of Appeals requested that Endo submit a response brief as part of its review process of Purdue’s petition for rehearing and rehearing en banc. Endo submitted this response on August 1, 2005. The Company remains confident that the prior decision of the Federal Circuit Court will remain in effect and intends to continue to pursue its antitrust claims against Purdue. The U.S. Food and Drug Administration had previously granted final approval of our abbreviated new drug application (ANDA) for all four strengths of the product in 2004. Our oxycodone extended-release tablets are AB-rated bioequivalent versions of OxyContin®, a product of The Purdue Frederick Company that is indicated for the management of moderate-to-severe pain when a continuous, around-the-clock analgesic is needed for an extended period of time. All OxyContin® strengths, as well as generics of the 80 mg strength, had combined 2004 U.S. sales of approximately $2 billion. We launched all four strengths of the product on June 7, 2005 and had net sales of $29.2 million for the three months ended June 30, 2005. The launch of this product will materially impact our future results.
     Our quarterly results have fluctuated in the past, and may continue to fluctuate. These fluctuations are primarily due to the timing of new product launches, purchasing patterns of our customers, market acceptance of our products, the impact of competitive products and pricing as well as charges incurred for compensation related to stock options and upfront, milestone and certain other payments made or accrued pursuant to licensing agreements.
Critical Accounting Policies and Estimates
     To understand our financial statements, it is important to understand our critical accounting policies and estimates. The preparation of our financial statements in conformity with accounting principles generally accepted in the United States requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Significant estimates and assumptions are required in the determination of sales deductions for estimated chargebacks, rebates, sales incentives and allowances, royalties and returns and losses. Significant estimates and assumptions are also required in the appropriateness of capitalization and amortization periods for identifiable intangible assets, inventories and related inventory reserves and the potential impairment of goodwill and other intangible assets. Some of these judgments can be subjective and complex, and, consequently, actual results may differ from these estimates. For any given individual estimate or assumption made by us, there may also be other estimates or assumptions that are reasonable. Although we believe that our estimates and assumptions are reasonable, they are based upon information available at the time the estimates and assumptions were made. Actual results may differ significantly from our estimates. Our most critical accounting policies and estimates are described below:

Table of Contents

Sales Deductions
     When we recognize revenue from the sale of our products, we simultaneously record an adjustment to revenue for estimated chargebacks, rebates, sales incentives and allowances, royalties and returns and losses. These provisions are estimated based on historical experience, estimated future trends, estimated customer inventory levels, current contract sales terms with our wholesale and indirect customers and other competitive factors. If the assumptions we used to calculate these adjustments do not appropriately reflect future activity, our financial position, results of operations and cash flows could be impacted. The provision for chargebacks is one of the most significant and the most complex estimate used in the recognition of our revenue. We establish contract prices for indirect customers who are supplied by our wholesale customers. A chargeback represents the difference between our invoice price to the wholesaler and the indirect customer’s contract price. Provisions for estimating chargebacks are calculated primarily using historical chargeback experience, estimated wholesaler inventory levels and estimated future trends. We also establish contracts with wholesalers, chain stores and indirect customers that provide for rebates, sales incentives and other allowances. Some customers receive rebates upon attaining established sales volumes. We estimate rebates, sales incentives and other allowances based upon the terms of the contracts with our customers, historical experience, estimated inventory levels of our customers and estimated future trends. We estimate an accrual for Medicaid rebates as a reduction of revenue at the time product sales are recorded. The Medicaid rebate reserve is estimated based upon the historical payment experience, historical relationship to revenues and estimated future trends. Medicaid pricing programs involve particularly difficult interpretations of statutes and regulatory guidance, which are complex and thus our estimates could differ from actual experience. Royalties represent amounts accrued pursuant to the license agreement with Hind Healthcare Inc. (Hind). Royalties are recorded as a reduction to net sales due to the nature of the license agreement and the characteristics of the license involvement by Hind in Lidoderm®. Royalties are paid to Hind at a rate of 10% of net sales of Lidoderm®. Our return policy allows customers to receive credit for expired products within three to six months prior to expiration and within one year after expiration. We estimate the provision for product returns based upon the historical experience of returns for each product, historical relationship to revenues, estimated future trends, estimated customer inventory levels and other competitive factors. We continually monitor the factors that influence each type of sales deduction and make adjustments as necessary.
Inventories
     Inventories consist of finished goods held for distribution, raw materials and work in process. Our inventories are stated at the lower of cost or market. Cost is determined by the first-in, first-out method. We write down inventories to net realizable value based on forecasted demand and market conditions, which may differ from actual results. Inventories also include costs associated with certain products prior to regulatory approval based on management’s judgment of probable future commercial use and net realizable value.
Goodwill and Other Intangibles
     Goodwill and other intangibles represent a significant portion of our assets and stockholders’ equity. As of June 30, 2005, goodwill and other intangibles comprised approximately 27% of our total assets and 40% of our stockholders’ equity. SFAS No. 142, Goodwill and Other Intangible Assets, (SFAS No. 142) prescribes a two-step method for determining goodwill impairment. In the first step, we determine the fair value of our one reporting unit. If the net book value of our reporting unit exceeds the fair value, we would then perform the second step of the impairment test which requires allocation of our reporting unit’s fair value to all of its assets and liabilities in a manner similar to a purchase price allocation, with any residual fair value being allocated to goodwill. An impairment charge will be recognized only when the implied fair value of our reporting unit’s goodwill is less than its carrying amount. As a result of the significance of goodwill, our results of operations and financial position in a future period could be negatively impacted should an impairment of goodwill occur.
     We have one reportable segment, pharmaceutical products. Goodwill arose as a result of the August 26, 1997 acquisition of certain branded and generic pharmaceutical products, related rights and certain assets of the then DuPont Merck Pharmaceutical Company (n/k/a Bristol-Myers Squibb Pharma Company) and the July 17, 2000 acquisition of Algos. Although goodwill arose in two separate transactions, the components of our operating segment have been integrated and are managed as one reporting unit. Our components extensively share assets and other resources with the other components of our business and have similar economic characteristics. In addition, our components do not maintain discrete financial information. Accordingly, the components of our business have been aggregated into one reporting unit and are evaluated as such for goodwill impairment. Goodwill is evaluated for impairment on an annual basis on January 1st of each year unless events or circumstances indicate that an impairment may have occurred between annual dates. On January 1, 2005 and 2004, our goodwill was evaluated for impairment and, based on the fair value of our reporting unit, no impairment was identified.

     The cost of licenses are either expensed immediately or, if capitalized, are stated at cost, less accumulated amortization and are amortized using the straight-line method over their estimated useful lives ranging from eleven to twenty years. The determination to capitalize amounts related to licenses is based on management’s judgments with respect to stage of development, the nature of the rights acquired, alternative future uses, developmental and regulatory issues and challenges, the net realizable value of such amounts based on projected sales of the underlying products, the commercial status of the underlying products and/or various other competitive factors. We determine amortization periods for licenses based on our assessment of various factors impacting estimated useful lives and cash flows of the acquired rights. Such factors include the expected launch date of the product, the strength of the intellectual property protection of the product and various other competitive, developmental and regulatory issues, and contractual terms. Significant changes to any of these factors may result in a reduction in the useful life of the license and an acceleration of related amortization expense, which could cause our operating income, net income and earnings per share to decrease. The value of these licenses is subject to continuing scientific, medical and marketplace uncertainty. During the six months ended June 30, 2005, the Company expensed $20 million with respect to the acquisitions of marketing and development license rights for two products that are currently in development. We expensed the cost of these license rights based on the fact that we acquired both marketing and development rights for products that do not have regulatory approval and that do not have currently identifiable alternative future uses. As such, it was determined that the cost of the right to develop the products and the cost of the right to market the products were inextricably linked and therefore expensed in the accompanying financial statements. Patents acquired in the Algos merger are stated at cost, less accumulated amortization, and are amortized using the straight-line method over their estimated useful lives of seventeen years.
     Licenses and patents are assessed for impairment, in accordance with Statement of Financial Accounting Standards No. 144, Accounting for the Impairment or Disposal of Long-Lived Assets (SFAS No. 144), whenever events or changes in circumstances indicate the carrying amount of the asset may not be recoverable. The impairment testing involves comparing the carrying amount of the asset to the forecasted undiscounted future cash flows of the product. In the event the carrying value of the asset exceeds the undiscounted future cash flows of the product and the carrying value is not considered recoverable, an impairment exists. An impairment loss is measured as the excess of the asset’s carrying value over its fair value, calculated using a discounted future cash flow method. An impairment loss would be recognized in net income in the period that the impairment occurs. Events giving rise to impairment are an inherent risk in the pharmaceutical industry and cannot be predicted. As a result of the significance of our amortizable intangibles, any recognized impairment loss could have a material adverse impact on our financial position and/or results of operations.

Compensation Related to Stock Options — Endo Pharma LLC Stock Option Plans
     In our 2001 fiscal year we incurred a non-cash charge of $37.3 million, in our 2002 fiscal year we recorded a non-cash charge of $34.7 million and in our 2003 fiscal year we recorded non-cash charges of $144.5 million, in each case for stock-based compensation relating to the vesting of options that were issued under the Endo Pharma LLC 1997 Amended and Restated Executive Stock Option Plan and the Endo Pharma LLC 1997 Amended and Restated Employee Stock Option Plan (together, the “Endo Pharma LLC 1997 Stock Option Plans”) and the Endo Pharma LLC 2000 Supplemental Employee Stock Option Plan and the Endo Pharma LLC 2000 Supplemental Executive Stock Option Plan (collectively, the “Endo Pharma LLC 2000 Supplemental Stock Option Plans”). Under the Endo Pharma LLC 1997 Stock Option Plans and the Endo Pharma LLC 2000 Supplemental Stock Option Plans, tranches of options vested if we attained certain stock price targets. As each tranche vested, we incurred a non-cash charge representing the difference between the market price of the shares underlying the options and the exercise price of such options. Upon exercise, no additional shares of our common stock will be issued, however, because these stock options are exercisable only into shares of our common stock that are held by Endo Pharma LLC. Accordingly, these stock options do not dilute the public stockholders. In addition, Endo Pharma LLC, and not us, will receive the exercise price payable in connection with these options. Further, the shares of common stock that individuals receive upon exercise of stock options granted pursuant to the Endo Pharma LLC 1997 Stock Option Plans and the Endo Pharma LLC 2000 Supplemental Stock Option Plans are currently subject to significant restrictions that are set forth in stockholders agreements.
     The Class C Endo Pharma LLC stock options (all of which are vested) become exercisable at the earlier of an exit event, as defined, or January 1, 2006. If the Class C stock options are not exercised by January 1, 2006, they would terminate. Although the Company has considered extending the term of the Class C stock options, following enactment of the 2004 Jobs Creation Act, an extension of the term of the stock options would result in adverse tax consequences for the option holders. As a result, the Company and Endo Pharma LLC are reviewing several alternatives which would allow approximately 22 million Class C stock options to be exercised before their expiration on January 1, 2006. Holders of stock options granted under the Endo Pharma LLC Stock Option Plans and shares of Company common stock received by such holders upon exercise of the options are bound by transfer restrictions pursuant to stockholders agreements. These transfer restrictions may be waived by Endo Pharma LLC at any time. The Company expects that Endo Pharma LLC will waive the transfer restrictions on a portion of the shares of Company common stock received by exercising option holders from Endo Pharma LLC at the time of exercise and that holders may sell a portion of the shares they receive upon exercise in an amount sufficient to satisfy such holders’ related tax and exercise price obligations. Alternatively, a portion of the shares of Company common stock to be received by option holders from Endo Pharma LLC upon exercise may be withheld to satisfy such holders’ related tax and exercise price obligations, and the Company’s tax withholding obligations in connection with such exercise, with the Company being required to satisfy such obligations in cash. The exercise of the Class C stock options is expected to generate a significant tax deduction for the Company and create a significant tax sharing payment obligation to Endo Pharma LLC pursuant to the tax sharing agreement. Upon exercise, option holders will receive shares of Company common stock currently owned by Endo Pharma LLC. Accordingly, no shares of Company common stock will be issued upon exercise of the Class C stock options.
     For a discussion of the tax sharing agreement between the Company and Endo Pharma LLC relating to the Endo Pharma LLC Stock Options, see “ — Liquidity and Capital Resources; Tax Sharing Agreement.”
     Compensation Related to Stock Options — Endo Pharmaceuticals Holdings Inc. 2000 and 2004 Stock Incentive Plans
     All the stock options we have granted pursuant to the Endo Pharmaceuticals Holdings Inc. 2000 and 2004 Stock Incentive Plans have exercise prices equal to the market price of our stock on the date granted and, under accounting principles generally accepted in the United States, a measurement date occurs on the date of each grant. Consequently, we have not incurred charges upon the vesting or exercise of these options. In December 2004, the FASB issued SFAS No. 123, Share-Based Payments (revised 2004), (SFAS No. 123(R)). This statement eliminates the option to apply the intrinsic value measurement provisions of APB Board Opinion No. 25, Accounting for Stock Issued to Employees, to stock compensation awards issued to employees. Rather, the Statement requires companies to measure the cost of employee services received in exchange for an award of equity instruments based on the grant date fair value of the award. That cost will be recognized over the period during which an employee is required to provide services in exchange for the award — the requisite service period (usually the vesting period). SFAS No. 123(R) will be effective for the Company’s fiscal year beginning January 1, 2006. The Company is currently evaluating the impact of the adoption of this statement on its financial statements.

Net Sales
     Our net sales consist of revenues from sales of our pharmaceutical products, less estimates for certain chargebacks, rebates, sales incentives and allowances, royalties and returns and losses. We recognize revenue when products are shipped and title and risk of loss has passed to the customer, which is typically upon delivery to the customer. Our shipping terms are generally free on board customer’s destination.

Three Months Ended June 30, 2005 Compared to the Three Months Ended June 30, 2004
     Net Sales. Net sales for the three months ended June 30, 2005 increased by 36% to $196.4 million from $144.0 million in the comparable 2004 period. This increase in net sales was primarily due to the increase in the net sales of Lidoderm®, the first FDA-approved product for the treatment of the pain of post-herpetic neuralgia and Percocet®. In addition, net sales of Frova®, DepoDurTM and our generic oxycodone extended release product were not included in net sales in the comparable 2004 period. These increases were partially offset by the reduction in the sales of certain of our generic products. Net sales of Lidoderm® increased to $100.5 million from $58.2 million in the comparable 2004 period. The increase primarily reflects the continued growth of the product as well as the reduction in inventory carried by our customers during the second quarter of 2004. In September 1999, we launched Lidoderm®, which continues to gain market share due to our ongoing promotional and educational efforts. Percocet® net sales increased to $24.8 million from $13.6 million in the comparable 2004 period substantially due to the reduction in inventory carried by our customers during the second quarter of 2004. Net sales of Frova® and DepoDurTM were $8.7 million and $2.3 million, respectively, for the three months ended June 30, 2005. We began shipping Frova® upon the closing of the license agreement in mid-August 2004 and initiated our promotional efforts in September 2004. We began shipping DepoDurTM in December 2004; however, we had deferred the recognition of revenue on all of our shipments until the three months ended June 30, 2005 due to the inability to reasonably estimate product returns prior to the three months ended June 30, 2005. Net sales of our generic products decreased 17% to $57.6 million from $69.0 million in the comparable 2004 period primarily due to the reduction in the net sales of our morphine sulfate extended release tablets and Endocet®, both of which experienced additional generic competition which has decreased both our market share as well as the price of these generic products. This decrease was partially offset by net sales of $29.2 million from our generic oxycodone extended release product, which we launched in June 2005. Generic competition with our products may have a material impact on our results of operations and cash flows in the future. We believe net sales for 2005 to be approximately $800 to $825 million. Further, we expect net sales of Lidoderm® to be approximately $390 to $400 million in 2005. Of course, there can be no assurance of Endo achieving these results.
     Gross Profit. Gross profit for the three months ended June 30, 2005 increased by 34% to $154.1 million from $115.1 million in the comparable 2004 period. Gross profit margins decreased to 78% from 80% due to the introduction of more costly single-pouch child-resistant packaging for Lidoderm® during the second quarter of 2004, product mix and continued pricing pressures on our generic products.
     Selling, General and Administrative Expenses. Selling, general and administrative expenses for the three months ended June 30, 2005 increased by 30% to $56.1 million from $43.0 million in the comparable 2004 period. This increase was primarily due to an increase in sales and promotional efforts in 2005 over the comparable 2004 period to support Lidoderm®, Frova® and DepoDurTM. The increase is also due to the support provided to our products and new product pipeline in anticipation of product launches.
     Research and Development Expenses. Research and development expenses for the three months ended June 30, 2005 decreased by $2.0 million to $17.2 million from $19.2 million in the comparable 2004 period. This decrease is primarily attributable to $10 million in milestone payments, incurred in the second quarter of 2004, to SkyePharma related to the FDA approval of DepoDurTM and the advancement of Propofol IDD-DTM into Phase III clinical development partially offset by our increased developmental efforts with respect to oxymorphone extended-release tablets and immediate-release tablets and the advancement of other recently acquired pipeline products in the second quarter of 2005.
     Depreciation and Amortization. Depreciation and amortization for the three months ended June 30, 2005 increased to $3.7 million from $2.3 million in the comparable 2004 period primarily due to an increase in amortization expense as a result of new license rights acquired during 2004 and an increase in depreciation expense as a result of an increase in capital expenditures.
     Interest Income, Net. Interest income, net for the three months ended June 30, 2005 was $2.1 million compared to $228,000 in the comparable 2004 period. This increase is substantially due to the interest income earned on our note receivable from Vernalis.
     Income Tax. Income tax for the three months ended June 30, 2005 increased to $30.2 million from $19.2 million in the comparable 2004 period. This increase is due to the increase in income before income tax for the three months ended June 30, 2005.

Six Months Ended June 30, 2005 Compared to the Six Months Ended June 30, 2004
     Net Sales. Net sales for the six months ended June 30, 2005 increased to $334.1 million from $297.5 million in the comparable 2004 period. This increase in net sales was primarily due to the increase in the net sales of Lidoderm® and Percocet®. In addition, net sales of Frova®, DepoDurTM and our generic oxycodone extended release product were not included in net sales in the comparable 2004 period. These increases were offset by the reduction in the sales of certain of our generic products. Net sales of Lidoderm® increased to $164.6 million from $123.6 million in the comparable 2004 period due to the continued prescription growth of the product. Percocet® net sales increased to $52.2 million from $44.4 million in the comparable 2004 period substantially due to the reduction in inventory carried by our customers during the second quarter of 2004. Net sales of Frova® and DepoDurTM were $14.8 million and $2.3 million, respectively, for the six months ended June 30, 2005. We began shipping Frova® upon the closing of the license agreement in mid-August 2004 and initiated our promotional efforts in September 2004. We began shipping DepoDurTM in December 2004; however, we had deferred the recognition of revenue on all of our shipments until the three months ended June 30, 2005 due to the inability to reasonably estimate product returns prior to the three months ended June 30, 2005. Net sales of our generic products decreased 22% to $94.9 million from $122.0 million in the comparable 2004 period primarily due to the reduction in the net sales of our morphine sulfate extended release tablets and Endocet®, both of which experienced additional generic competition which has decreased both our market share as well as the price of these generic products. This decrease was partially offset by net sales of $29.2 million from our generic oxycodone extended release product, which we launched in June 2005. Generic competition with our products may have a material impact on our results of operations and cash flows in the future.
     Gross Profit. Gross profit for the six months ended June 30, 2005 increased by 11% to $262.3 million from $235.7 million in the comparable 2004 period. Gross profit margins decreased to 78% from 79% due to the introduction of more costly single-pouch child-resistant packaging for Lidoderm® during the second quarter of 2004, product mix and continued pricing pressures on our generic products.
     Selling, General and Administrative Expenses. Selling, general and administrative expenses for the six months ended June 30, 2005 increased by 34% to $109.7 million from $81.8 million in the comparable 2004 period. This increase was primarily due to an increase in sales and promotional efforts in 2005 over the comparable 2004 period to support Lidoderm®, Frova® and DepoDurTM. The increase is also due to the support provided to our products and new product pipeline in anticipation of product launches.
     Research and Development Expenses. Research and development expenses for the six months ended June 30, 2005 increased by 66% to $48.0 million from $29.0 million in the comparable 2004 period. This increase is primarily related to $20 million expensed during the six months ended June 30, 2005 related to the upfront payments to license the topical ketoprofen patch and the transdermal sufentanil patch, our increased developmental efforts with respect to oxymorphone extended-release tablets and immediate-release tablets and the advancement of other recently acquired products partially offset by $10 million in milestone payments, incurred in the second quarter of 2004, to SkyePharma related to the FDA approval of DepoDurTM and the advancement of Propofol IDD-DTM into Phase III clinical development.
     Depreciation and Amortization. Depreciation and amortization for the six months ended June 30, 2005 increased to $7.3 million from $4.1 million in the comparable 2004 period primarily due to an increase in amortization expense as a result of new license rights acquired during 2004 and an increase in depreciation expense as a result of an increase in capital expenditures.
     Loss on Disposal of Other Intangible. The loss on disposal of other intangible is due to the termination of our collaboration agreement with Lavipharm and the resulting write-off of the unamortized portion of the upfront license fee of $0.8 million. The loss also includes a $3 million termination payment made by us to Lavipharm.
     Interest Income, Net. Interest income, net for the six months ended June 30, 2005 was $4.0 million compared to $218,000 in the comparable 2004 period. This increase is substantially due to the interest income earned on our note receivable from Vernalis.
     Income Tax. Income tax for the six months ended June 30, 2005 decreased to $38.5 million from $44.5 million in the comparable 2004 period. This decrease is due to the decrease in income before income tax for the six months ended June 30, 2005.

Liquidity and Capital Resources
     Our principal source of liquidity is cash generated from operations. Under our credit facility, we may borrow up to $75.0 million on a revolving basis for certain purposes as described below. Our principal liquidity requirements are for working capital for operations, acquisitions, licenses, milestone payments and capital expenditures.
     Net Cash Provided by Operating Activities. Net cash provided by operating activities increased to $22.7 million for the six months ended June 30, 2005 from $15.1 million for the six months ended June 30, 2004. Significant components of the $22.7 million of operating cash flows for the six months ended June 30, 2005 included net income of $62.9 million, an increase in income taxes payable of $24.3 million due to a higher tax provision resulting from increased earnings as well as the timing of estimated tax payments, increases in accounts payable and accrued expenses of $13.5 million and depreciation expense of $7.3 million partially offset by an $86.1 million increase in accounts receivable primarily due to the timing and volume of net sales during the three months ended June 30, 2005.
     Net Cash Used in Investing Activities. Net cash used in investing activities decreased to $4.8 million for the six months ended June 30, 2005 from $12.7 million for the six months ended June 30, 2004. During the six months ended June 30, 2005, the Company paid $4.8 million for capital expenditures. During the six months ended June 30, 2004, the Company paid $7.3 million in license fees, a termination penalty of $3 million to Lavipharm and had capital expenditures of $2.6 million primarily related to our new research and development facility in Long Island, New York.
     Net Cash Used in Financing Activities. Net cash used in financing activities increased to $19.6 million for the six months ended June 30, 2005 from $0.4 million for the six months ended June 30, 2004. The increase is primarily due to a $21.4 million payment to Endo Pharma LLC pursuant to the tax sharing agreement and an increase in capital lease obligation repayments partially offset by an increase in the proceeds received from the exercise of employee stock options.
     Credit Facility. In December 2001, we amended and restated our senior secured credit facility with a number of lenders. This amended and restated credit facility provides us with a line of credit of $75.0 million. The line of credit matures on December 21, 2006. Any loans outstanding under the amended and restated credit facility are secured by a first priority security interest in substantially all of our assets. The credit facility contains representations and warranties, covenants, including a covenant requiring us to maintain minimum EBITDA of $50 million over the prior four-quarter period, events of default and other provisions customarily found in similar agreements. Our ability to borrow under the credit facility is dependent, among other things, on our compliance with those provisions. On April 30, 2004, we amended our credit facility to allow us to file a shelf registration statement on Form S-3,which we initially filed on April 30, 2004, providing for the sale by Endo Pharma LLC and certain other selling stockholders to be named therein, including certain of our directors and officers, from time to time, of up to 30 million currently issued and outstanding shares of our common stock. On July 13, 2004, we amended our credit facility to allow us to enter in the transaction with Vernalis. As of June 30, 2005, we have not borrowed any amounts under our credit facility.
     Tax Sharing Agreement. On July 14, 2000, Endo Pharma LLC was formed in connection with the Algos merger to ensure that the stock options granted pursuant to the Endo Pharma LLC Stock Option Plans diluted only the Endo common stock held by persons and entities that held such shares prior to our merger with Algos. Endo Pharma LLC is a limited liability company that currently holds a significant portion of our common stock, in which affiliates of Kelso & Company and certain members of management have an interest. Upon the exercise of these stock options, only currently outstanding shares of our common stock held by Endo Pharma LLC will be delivered. Because Endo Pharma LLC, and not us, will provide the shares upon the exercise of these options, we have entered into a tax sharing agreement with Endo Pharma LLC under which we are required to pay to Endo Pharma LLC the amount of the tax benefits usable by us as a result of the exercise of these stock options into shares of our common stock held by Endo Pharma LLC. As of June 30, 2005, approximately 10.6 million of these stock options had been exercised into shares of our common stock held by Endo Pharma LLC. Upon exercise of any of these Endo Pharma LLC stock options, we generally will be permitted to deduct as a compensation charge, for federal income tax purposes, an amount equal to the difference between the market price of our common stock and the exercise price paid upon exercise of these options (as of June 30, 2005, approximately $149 million), which is estimated to result in a tax benefit amount of approximately $57 million. Under the tax sharing agreement, we are required to pay this $57 million to Endo Pharma LLC to the extent that a compensation charge deduction is usable by us to reduce our taxes and based upon the assumption that all other deductions of Endo are used prior thereto.

     Using a weighted average exercise price of $2.60 per share and an assumed effective tax rate of 38.3%, if all 36.3 million stock options under the Endo Pharma LLC Stock Option Plans were vested and exercised (including the 10.6 million stock options already exercised as discussed above):
    upon exercise, assuming the market price of our common stock is then $20.00 per share, we generally would be able to deduct, for federal income tax purposes, compensation of approximately $632 million, which could result in a tax benefit amount of approximately $242 million payable to Endo Pharma LLC.
 
    upon exercise, assuming the market price of our common stock is then $25.00 per share, we generally would be able to deduct, for federal income tax purposes, compensation of approximately $813 million, which could result in a tax benefit amount of approximately $311 million payable to Endo Pharma LLC.
 
    upon exercise, assuming the market price of our common stock is then $30.00 per share, we generally would be able to deduct, for federal income tax purposes, compensation of approximately $994 million, which could result in a tax benefit amount of approximately $381 million payable to Endo Pharma LLC.
     On April 30, 2004, the tax sharing agreement was amended to provide for a specific schedule upon which payments currently contemplated by the tax sharing agreement would be made. The amended tax sharing agreement provides that the amount of the tax benefits usable by us in each such year will be paid to Endo Pharma LLC in two installments: (i) 50% of the estimated amount shall be paid within 15 business days of our receipt from our independent registered public accounting firm of an opinion on our final audited financial statements, and (ii) the remaining amount shall be paid within 30 business days of the filing of our federal income tax return.

     In 2004, we paid $13.5 million to Endo Pharma LLC to satisfy the tax sharing obligations attributable to 2001, 2002 and 2003. Since 3.8 million shares underlying stock options granted under the Endo Pharma LLC stock option plans were exercised into common stock and sold in the offering on August 9, 2004, at a price of $17.46, with a weighted average exercise price of $2.44, an assumed tax rate of 38.3% and assuming the attributable compensation charge deductions are usable to reduce our taxes related to 2004, we are obligated to pay Endo Pharma LLC a tax benefit of approximately $22 million. In addition, since 2.8 million shares underlying stock options granted under the Endo Pharma LLC stock option plans were exercised into common stock and sold in the offering on November 29, 2004, at a price of $20.02, with a weighted average exercise price of $2.44, an assumed tax rate of 38.3% and assuming the attributable compensation charge deductions are usable to reduce our taxes related to 2004, we are obligated to pay Endo Pharma LLC a tax benefit of approximately $19 million. Fifty percent of the tax benefit amount attributable to these two 2004 offerings and other Endo Pharma LLC stock option exercises in 2004, aggregating $21.4 million, was due and was paid within 15 business days of the date we received an opinion on our audited 2004 financial statements from our independent registered public accounting firm and the remaining fifty percent of the tax benefit amount attributable to 2004 is due within 30 business days of the date on which we file our 2004 tax return with the Internal Revenue Service (which we estimate will occur in September 2005). As of June 30, 2005, approximately $22.2 million is payable to Endo Pharma LLC related to estimated tax sharing payments that we are obligated to pay which are attributable to 2004 and 2005. All payments made and accrued pursuant to the tax sharing agreement have been reflected as a reduction of stockholders’ equity in the accompanying financial statements. The estimated tax benefit amount payment to Endo Pharma LLC attributable to Endo Pharma LLC stock options exercised may increase if certain holders of Endo Pharma LLC stock options exercise additional stock options in the future.
     On April 30, 2004, we filed a shelf registration statement on Form S-3, as amended on June 10, June 14 and June 25, 2004, providing for the sale by Endo Pharma LLC and certain other selling stockholders named therein, including certain of our directors and officers, from time to time, of up to 30 million currently issued and outstanding shares of our common stock. The shelf registration statement was declared effective by the Securities and Exchange Commission on June 28, 2004. After the closing of the August 9 and November 29, 2004 offerings, which totaled 19 million shares, up to 11 million shares remain eligible for sale by Endo Pharma LLC under this shelf registration statement. The shelf registration statement enables one or more offerings of common stock, subject to market conditions. The nature and terms of any offering will be established at the time of the offering and set forth in a prospectus supplement. Any offering would most likely trigger an additional tax sharing payment to Endo Pharma LLC, would not increase the number of our outstanding shares of common stock and we would not receive any proceeds from any offering covered by this shelf registration. Endo Pharma LLC has informed us that, subject to a variety of factors, including market conditions and stock price levels, it may initiate additional secondary offerings of our common stock in the future.
     The Class C Endo Pharma LLC stock options (all of which are vested) become exercisable at the earlier of an exit event, as defined, or January 1, 2006. If the Class C stock options are not exercised by January 1, 2006, they would terminate. Although the Company has considered extending the term of the Class C stock options, following enactment of the 2004 Jobs Creation Act, an extension of the term of the stock options would result in adverse tax consequences for the option holders. As a result, the Company and Endo Pharma LLC are reviewing several alternatives which would allow approximately 22 million Class C stock options to be exercised before their expiration on January 1, 2006. Holders of stock options granted under the Endo Pharma LLC Stock Option Plans and shares of Company common stock received by such holders upon exercise of the options are bound by transfer restrictions pursuant to stockholders agreements. These transfer restrictions may be waived by Endo Pharma LLC at any time. The Company expects that Endo Pharma LLC will waive the transfer restrictions on a portion of the shares of Company common stock received by exercising option holders from Endo Pharmc LLC at the time of exercise and that holders may sell a portion of the shares they receive upon exercise in an amount sufficient to satisfy such holders’ related tax and exercise price obligations. Alternatively, a portion of the shares of Company common stock to be received by option holders from Endo Pharmc LLC upon exercise may be withheld to satisfy such holders’ related tax and exercise price obligations, and the Company’s tax withholding obligations in connection with such exercise, with the Company being required to satisfy such obligations in cash. The exercise of the Class C stock options is expected to generate a significant tax deduction for the Company and create a significant tax sharing payment obligation to Endo Pharmc LLC pursuant to the tax sharing agreement. Upon exercise, option holders will receive shares of Company common stock currently owned by Endo Pharmc LLC. Accordingly, no shares of Company common stock will be issued upon exercise of the Class C stock options.

     Settlement of Contingent Obligation. During the six months ended June 30, 2005, the Company reached a tentative agreement with an individual to compensate him a total of $2 million for past services rendered to the Company. This agreement was finalized on May 10, 2005, and the $2 million has been recorded in selling, general and administrative expenses during the six months ended June 30, 2005. It is anticipated that Endo Pharma LLC will make these payments totaling $2 million on behalf of the Company, and they will be treated as a capital contribution by Endo Pharma LLC once payments are made. Endo Pharma LLC made a payment of $800,000, pursuant to the settlement agreement, on behalf of the Company in May 2005 and this payment has been treated as a capital contribution in the accompanying financial statements. The remaining obligation pursuant to this agreement is $1.2 million as of June 30, 2005.
     Licenses and Collaboration Agreements. We enter into licenses and collaboration agreements to develop, use, market and promote certain of our products from or with other pharmaceutical companies and universities. A description of the material developments with respect to our significant third party license and collaboration agreements that took place during the six months ended June 30, 2005 follows:
DURECT Corporation
     On March 14, 2005, we announced that we signed an agreement that gives us the exclusive license to develop and commercialize DURECT’s sufentanil-containing transdermal patch in the U.S. and Canada (the “DURECT Sufentanil Agreement”). The sufentanil patch, which is in early-stage clinical development, employs DURECT’s proprietary TRANSDUR™ drug-adhesive matrix formulation and is intended to provide relief of moderate-to-severe chronic pain for up to seven days. We have assumed all remaining development and regulatory filing responsibility for this product, including the funding thereof. Under the terms of the DURECT Sufentanil Agreement, in April 2005, we paid DURECT a $10 million upfront fee that has been expensed in the first quarter of 2005 as research and development, with additional payments of approximately $35 million upon achievement of predetermined regulatory and commercial milestones. We will also pay royalties to DURECT on net sales of the sufentanil transdermal patch. In addition, the DURECT Sufentanil Agreement also contains terms and conditions customary for this type of arrangement, including representations, warranties, indemnities and termination rights. The DURECT Sufentanil Agreement will continue in effect until terminated. The DURECT Sufentanil Agreement provides each party with specified termination rights, including the right of each party to terminate the DURECT Sufentanil Agreement upon material breach of the DURECT Sufentanil Agreement by the other party and the right of Endo to terminate the DURECT Sufentanil Agreement at any time without cause subject to a specified notice period.
ProEthic Pharmaceuticals, Inc.
     On March 14, 2005, we entered into an agreement with ProEthic Pharmaceuticals, Inc. for the U.S. and Canadian rights to develop and commercialize a once-daily ketoprofen-containing topical patch. Ketoprofen is a non-steroidal anti-inflammatory drug (NSAID) generally used for the treatment of inflammation and pain and currently available in the U.S. only in oral form. Currently in Phase II clinical trials in the U.S., the ketoprofen patch is being developed for the localized treatment of acute pain associated with soft-tissue injuries such as tendonitis or joint sprains and strains. Two Phase III placebo-controlled studies in soft-tissue injury and ankle sprains have been completed in Europe by ProEthic’s European partner APR Applied Pharma Research AG, with statistically significant results. Under the terms of the agreement, in March 2005, we made a $10 million upfront payment that has expensed in the first quarter of 2005 as research and development, and could be required to make additional payments of approximately $13.0 million for the achievement of certain regulatory and other milestones. We will also pay royalties on net sales of the ketoprofen patch. In addition, the license agreement also contains customary terms and conditions, including representations, warranties, indemnities and termination rights. The term of the license agreement shall be until the later of (i) the expiration of the patents or (ii) the tenth (10th) anniversary of the date of the first commercial sale of the product. We can terminate the agreement at any time upon no more than ninety (90) days’ written notice.
SkyePharma, Inc.
     In December 2002, we entered into a Development and Marketing Strategic Alliance Agreement with SkyePharma, Inc. and SkyePharma Canada, Inc. relating to two of SkyePharma’s patented development products, DepoDur™, previously referred to as DepoMorphine™, and Propofol IDD-D™ (collectively, the “Skye Products”). Under the terms of the agreement, Endo received an exclusive license to the U.S. and Canadian marketing and distribution rights for the Skye Products, with options for certain other SkyePharma development products. In return, Endo made a $25 million upfront payment to SkyePharma, which we capitalized as an intangible asset representing the fair value of the exclusive license of these distribution and marketing rights. We were amortizing this intangible asset over its useful life of 17 years.

Table of Contents

     During the six months ended June 30, 2005, we recorded a receivable from SkyePharma of $5 million based upon the achievement of certain criteria as specified in the agreement. This receivable has been recorded as a reduction to our recorded intangible asset and the intangible asset is now being amortized over its remaining useful life of 15 years.
Vernalis Development Limited
     On July 1, 2005, we entered into a co-promotion Agreement with Vernalis. The co-promotion agreement is related to that certain license agreement that we entered into on July 14, 2004 with Vernalis, under which Vernalis agreed to exclusively license to us rights to market the product Frova® (frovatriptan) in North America. Pursuant to the license agreement, Vernalis had retained rights to co-promote Frova® in the United States. Vernalis has exercised its co-promotion option and the co-promotion agreement sets forth the detailed terms and conditions governing such co-promotion and amends, restates and supersedes certain sections of the license agreement. Under the terms of the co-promotion agreement, we will reimburse Vernalis for certain defined costs of their sales personnel beginning in January 2006.
     Fluctuations. Our quarterly results have fluctuated in the past, and may continue to fluctuate. These fluctuations are primarily due to the timing of new product launches, purchasing patterns of our customers, market acceptance of our products, the impact of competitive products and pricing as well as charges incurred for compensation related to stock options and upfront, milestone and certain other payments made or accrued pursuant to licensing agreements. Further, a substantial portion of our net sales are through three wholesale drug distributors who in turn supply our products to pharmacies, hospitals and physicians. Accordingly, we are potentially subject to a concentration of credit risk with respect to our trade receivables.
     Growth Opportunities. We continue to evaluate growth opportunities including strategic investments, licensing arrangements and acquisitions of product rights or technologies, which could require significant capital resources.
     Non-U.S. Operations. We currently have no operations outside of the United States. As a result, fluctuations in foreign currency exchange rates do not have a material effect on our financial statements.
     Inflation. We do not believe that inflation had a material adverse effect on our financial statements for the periods presented.
Recent Accounting Pronouncements
     In November 2004, the FASB issued Statement of Financial Accounting Standards No. 151, Inventory Costs, an amendment of ARB No. 43, Chapter 4. The purpose of this statement is to clarify the accounting of abnormal amounts of idle facility expense, freight, handling costs and waste material. ARB No. 43 stated that under some circumstances these costs may be so abnormal that they are required to be treated as current period costs. SFAS 151 requires that these costs be treated, as current period costs regardless if they meet the criteria of “so abnormal.” In addition, the statement requires that allocation of fixed production overheads to the costs of conversion be based on the normal capacity of the production facilities. The provision of this Statement shall be effective for inventory costs incurred during fiscal years beginning after June 15, 2005. The adoption of SFAS 151 is not expected to have a material impact on the Company’s results of operations or financial position.
     In December 2004, the FASB issued SFAS No. 153, Exchanges of Nonmonetary Assets, an amendment of APB Opinion No. 29. SFAS 153 is effective for nonmonetary asset exchanges occurring in fiscal periods beginning after June 15, 2005, with earlier application permitted. The adoption of SFAS 153 is not expected to have a material impact on the Company’s results of operations or financial position.
     In December 2004, the FASB issued SFAS No. 123(R), Share-Based Payments (revised 2004). This statement eliminates the option to apply the intrinsic value measurement provisions of APB Board Opinion No. 25, Accounting for Stock Issued to Employees, to stock compensation awards issued to employees. Rather, the Statement requires companies to measure the cost of employee services received in exchange for an award of equity instruments based on the grant date fair value of the award. That cost will be recognized over the period during which an employee is required to provide services in exchange for the award — the requisite service period (usually the vesting period). In March 2005, the SEC staff expressed their views with respect to SFAS No. 123(R) in Staff Accounting Bulletin No. 107, Share-Based Payment, (SAB 107). SAB 107 provides guidance on valuing options. SFAS 123(R) will be effective for the Company’s fiscal year beginning January 1, 2006. The Company is currently evaluating the impact of the adoption of this statement on its financial statements.

     In March 2005, the FASB issued FASB Interpretation No. 47, Accounting for Conditional Asset Retirement Obligations, (FIN 47).   FIN 47 is an interpretation of SFAS No. 143, Asset Retirement Obligations, which was issued in June 2001. FIN 47 was issued to address diverse accounting practices that have developed with regard to the timing of liability recognition for legal obligations associated with the retirement of a tangible long-lived asset in which the timing and/or method of settlement are conditional on a future event that may or may not be within the control of the entity. According to FIN 47, uncertainty about the timing and/or method of settlement of a conditional asset retirement obligation should be factored into the measurement of the liability when sufficient information exists. FIN 47 also clarifies when an entity would have sufficient information to reasonably estimate the fair value of an asset retirement obligation. FIN 47 is effective no later than December 31, 2005 for the Company. The Company is currently evaluating the impact of the adoption of FIN 47 on its financial statements.
     In May 2005, the FASB issued SFAS No. 154, Accounting Changes and Error Corrections, a replacement of APB Opinion No. 20 and Statement No. 3. SFAS 154 changes the requirements for the accounting and reporting of a change in accounting principle. SFAS 154 applies to all voluntary changes in accounting principle as well as to changes required by an accounting pronouncement that does not include specific transition provisions. SFAS 154 is effective for accounting changes and corrections of errors made in fiscal years beginning after December 15, 2005. The adoption of SFAS 154 is not expected to have a material impact on the Company’s results of operations or financial position.
Item 3. Quantitative and Qualitative Disclosures about Market Risk.
     On December 21, 2001, we entered into a new credit facility that provides for a line of credit of $75.0 million. On April 30, 2004, we amended our credit facility to allow us to file a shelf registration statement on Form S-3, which we initially filed on April 30, 2004. On July 13, 2004, we amended our credit facility to allow us to enter in the transaction with Vernalis. Borrowings under the new credit facility are variable rate borrowings. There are no amounts outstanding under the new credit facility. We do not utilize financial instruments for trading purposes and hold no derivative financial instruments that could expose us to significant market risk. We monitor interest rates and enter into interest rate agreements as considered appropriate.
     As of June 30, 2005 and December 31, 2004, we had no assets or liabilities that have significant interest rate sensitivity.
     At June 30, 2005, we had publicly traded equity securities comprised of DURECT Corporation common stock at fair value totaling $7.8 million in “Other assets.” The fair value of this investment is subject to significant fluctuations due to volatility of the stock market and changes in general economic conditions. Based on the fair value of the publicly traded equity securities we held at June 30, 2005, an assumed 25%, 40% and 50% adverse change in the market prices of this security would result in a corresponding decline in total fair value of approximately $2.0 million, $3.1 million and $3.9 million, respectively.
Item 4. Controls and Procedures.

     Internal Control Over Financial Reporting

Item 1. Legal Proceedings.
     Purdue Pharma L.P., et al. v. Endo Pharmaceuticals Inc., et al., Index No. 00 Civ. 8029 (SHS) (S.D.N.Y.); Purdue Pharma L.P., et al. v. Endo Pharmaceuticals Inc., et al., Index No. 01 Civ. 2109 (SHS) (S.D.N.Y.); Purdue Pharma L.P., et al. v. Endo Pharmaceuticals Inc., et al., Index No. 01 Civ. 8177 (SHS) (S.D.N.Y.)
     On October 20, 2000, The Purdue Frederick Company and related companies (Purdue Frederick) filed suit against us and our subsidiary, Endo Pharmaceuticals Inc. (EPI), in the U.S. District Court for the Southern District of New York alleging that EPI’s bioequivalent version of Purdue Frederick’s OxyContin® (oxycodone hydrochloride extended-release tablets), 40mg strength, infringes three of its patents. This suit arose after EPI provided the plaintiffs with notice that its ANDA submission for a bioequivalent version of Purdue Frederick’s OxyContin®, 40mg strength, challenged the listed patents for OxyContin® 40mg tablets. On March 13, 2001, Purdue Frederick filed a second suit against us and EPI in the U.S. District Court for the Southern District of New York alleging that EPI’s bioequivalent versions of Purdue Frederick’s OxyContin®, 10mg and 20mg strengths, infringe the same three patents. This suit arose from EPI having amended its earlier ANDA on February 9, 2001 to add bioequivalent versions of the 10mg and 20mg strengths of OxyContin®. On August 30, 2001, Purdue Frederick filed a third suit against us and EPI in the U.S. District Court for the Southern District of New York alleging that EPI’s bioequivalent version of Purdue Frederick’s OxyContin®, 80mg strength, infringes the same three patents. This suit arose from EPI having amended its earlier ANDA on July 30, 2001 to add the bioequivalent version of the 80mg strength of OxyContin®.
     For each of the 10mg, 20mg, 40mg and 80mg strengths of this product, EPI made the required Paragraph IV certification against the patents listed in the FDA’s Orange Book as covering these strengths of OxyContin®. EPI pleaded counterclaims that the patents asserted by Purdue Frederick are invalid, unenforceable and/or not infringed by EPI’s formulation of oxycodone hydrochloride extended-release tablets, 10mg, 20mg, 40mg and 80mg strengths. EPI also counterclaimed for antitrust damages based on allegations that Purdue Frederick obtained the patents through fraud on the United States Patent and Trademark Office and is asserting them while aware of their invalidity and unenforceability.
     The trial of the patent claims in all three of the suits against us and EPI concluded on June 23, 2003. On January 5, 2004, the district court issued an opinion and order holding that, while Endo infringes the three Purdue patents, the patents are unenforceable due to inequitable conduct. The district court, therefore, dismissed the patent claims against us and EPI, declared the patents invalid, and enjoined Purdue from further enforcement of the patents. Purdue filed an appeal, as well as motions to expedite the appeal and to stay the injunction against enforcement of the patents until the appeal is resolved. Both motions were denied on March 18, 2004. In turn, we have cross-appealed the district court’s infringement ruling. Briefing on the appeal and cross-appeal concluded in July 2004. By an earlier order, the judge bifurcated the antitrust counterclaims for a separate and subsequent trial. On November 3, 2004, the oral arguments relating to the appeal of this case were heard by the U.S. Court of Appeals for the Federal Circuit in Washington, D.C., at which hearing both sides presented their arguments before a three-judge panel. On June 7, 2005, we announced that the U.S. Court of Appeals for the Federal Circuit in Washington, D.C., had affirmed the Opinion and Order issued in Endo’s favor by the U.S. District Court for the Southern District of New York on January 5, 2004. This affirmance by the Federal Circuit Court dismisses the claims that Endo’s oxycodone extended-release tablets, 10mg, 20mg, 40mg, and 80mg, a bioequivalent version of Purdue Frederick’s OxyContin®, infringe Purdue’s U.S. Patent Nos. 5,549,912, 5,508,042 and 5,656,295, and permanently enjoins Purdue from enforcing these patents. On June 21, 2005, Purdue filed a petition with the Federal Circuit seeking rehearing of the case by the panel that issued the June 7, 2005 decision, or alternatively by the entire court. On July 22, 2005, the Federal Circuit Court of Appeals requested that Endo submit a response brief as part of its review process of Purdue’s petition for rehearing and rehearing en banc. Endo submitted this response on August 1, 2005. The Company remains confident that the prior decision of the Federal Circuit Court will remain in effect and intends to continue to pursue its antitrust claims against Purdue.
     Litigation similar to that described above may also result from products we currently have in development, as well as those that we may develop in the future. We, however, cannot predict the timing or outcome of any such litigation, or whether any such litigation will be brought against us.

     Linda Serafin, et al. v. Purdue Pharma L.P., et al., No. 103031/04 (Supreme Court of the State of New York, County of New York)
     On February 27, 2004, EPI was named, along with three other pharmaceutical companies, a hospital, and a doctor, as a defendant in a lawsuit filed by Linda Serafin and Michael Serafin in the Supreme Court of the State of New York, County of New York. According to the complaint, each of the pharmaceutical companies manufactured or distributed the drugs oxycodone and OxyContin®. The complaint alleges that EPI and another defendant manufactured oxycodone, OxyContin® and/or Percocet®. The complaint alleges that the defendants failed to adequately warn about the dangers involved with these drugs and that as a result of this failure to warn, plaintiffs sustained injury. EPI intends to defend itself vigorously in this case.
     Litigation similar to that described above may also be brought by other plaintiffs in other jurisdictions. However, we cannot predict the timing or outcome of any such litigation, or whether any such litigation will be brought against us.
     Pricing Litigation
     A number of cases, brought by local and state government entities, are pending that allege generally that EPI and numerous other pharmaceutical companies reported false pricing information in connection with certain drugs that are reimbursable under Medicaid. These cases generally seek damages, treble damages, disgorgement of profits, restitution and attorneys’ fees. The federal court cases have been or are in the process of being consolidated in the United States District Court for the District of Massachusetts under the Multidistrict Litigation Rules as In re: Pharmaceutical Industry Average Wholesale Price Litigation, MDL 1456. The following previously reported cases have been consolidated into one consolidated complaint in MDL 1456: City of New York v. Abbott Laboratories, Inc., et al.; County of Albany v. Abbott Laboratories, Inc., et al.; County of Allegany v. Abbott Laboratories, Inc., et al.; County of Broome v. Abbott Laboratories, Inc., et al.; County of Cattaraugus v. Abbott Laboratories, Inc., et al; County of Cayuga v. Abbott Laboratories, Inc., et al.; County of Chautauqua v. Abbott Laboratories, Inc., et al.; County of Chenango v. Abbott Laboratories, Inc., et al.; County of Fulton v. Abbott Laboratories, Inc., et al.; County of Genesee v. Abbott Laboratories, Inc., et al.; County of Greene v. Abbott Laboratories, Inc., et al.; County of Herkimer v. Abbott Laboratories, Inc., et al.; County of Monroe v. Abbott Laboratories, Inc., et al.; County of Oneida v. Abbott Laboratories, Inc., et al.; County of Onondaga v. Abbott Laboratories, Inc., et al.; County of Rensselaer v. Abbott Laboratories, Inc., et al.; County of Rockland v. Abbott Laboratories, Inc., et al.; County of Saratoga v. Abbott Laboratories, Inc., et al.; County of St. Lawrence v. Abbott Laboratories, Inc., et al.; County of Steuben v. Abbott Laboratories, Inc., et al.; County of Suffolk v. Abbott Laboratories, Inc., et al.; County of Tompkins v. Abbott Laboratories, Inc., et al.; County of Warren v. Abbott Laboratories, Inc., et al.; County of Washington v. Abbott Laboratories, Inc., et al.; County of Wayne v. Abbott Laboratories, Inc., et al.; County of Westchester v. Abbott Laboratories, Inc., et al; and County of Yates v. Abbott Laboratories, Inc., et al. Four previously unreported federal cases have been filed against EPI and numerous other pharmaceutical companies and have been consolidated with the cases listed above in the consolidated complaint in MDL 1456. Those cases are: County of Jefferson v. Abbott Laboratories, Inc., et al., filed in June 2005 in the United States District Court for the Northern District of New York; County of Madison v. Abbott Laboratories, Inc., et al., filed in June 2005 in the United States District Court for the Northern District of New York; County of Niagra v. Abbott Laboratories, Inc., et al., filed in June 2005 in the United States District Court for the Western District of New York; and County of Putnam v. Abbott Laboratories, Inc., et al., filed in May 2005 in the United States District Court for the Southern District of New York. Nine new federal cases naming EPI in addition to numerous other pharmaceutical companies have been filed under seal. These cases will likely be transferred to MDL 1456 and consolidated into the consolidated complaint in MDL 1456 with the other cases listed above. The nine new cases are: County of Columbia v. Abbott Laboratories, Inc., et al., filed in July 2005 in the United States District Court for the Northern District of New York; County of Cortland v. Abbott Laboratories, Inc., et al., filed in July 2005 in the United States District Court for the Northern District of New York; County of Dutchess v. Abbott Laboratories, Inc., et al., filed in July 2005 in the United States District Court for the Southern District of New York; County of Essex v. Abbott Laboratories, Inc., et al., filed in July 2005 in the United States District Court for the Northern District of New York; County of Lewis v. Abbott Laboratories, Inc., et al., filed in July 2005 in the United States District Court for the Northern District of New York; County of Ontario v. Abbott Laboratories, Inc., et al., filed in July 2005 in the United States District Court for the Western District of New York; County of Orleans v. Abbott Laboratories, Inc., et al., filed in July 2005 in the United States District Court for the Western District of New York; County of Schuyler v. Abbott Laboratories, Inc., et al., filed in July 2005 in the United States District Court for the Western District of New York; and County of Seneca v. Abbott Laboratories, Inc., et al., filed in July 2005 in the United States District Court for the Western District of New York. One previously reported case filed in state court and removed to federal court is in the process of being transferred to MDL 1456: County of Erie v. Abbott Laboratories, Inc., et al.

     There is also a similar case pending in federal court in Alabama against EPI and numerous other pharmaceutical companies: State of Alabama v. Abbott Laboratories, Inc., et al., filed in January 2005 in the Circuit Court of Montgomery County, Alabama and removed to the United States District Court for the Middle District of Alabama on July 13, 2005. This case is in the process of being transferred to MDL 1456.
     The Company intends to contest all of these cases vigorously. Litigation similar to that described above may also be brought by other plaintiffs in various jurisdictions. However, we cannot predict the timing or outcome of any such litigation, or whether any such litigation will be brought against the Company.
     Other Legal Proceedings
     In addition to the above proceedings, we are involved in, or have been involved in, arbitrations or various other legal proceedings that arise from the normal course of our business. We cannot predict the timing or outcome of these claims and other proceedings. Currently, we are not involved in any arbitration and/or other legal proceeding that we expect to have a material effect on our business, financial condition, results of operations or cash flows.
