FORWARD LOOKING STATEMENTS

This document contains information that includes or is based on “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended, or the Securities Act, and Section 21E of the Securities Exchange Act of 1934, as amended, or the Exchange Act. These statements, including estimates of future net sales, future expenses, 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,” “plan,” “will,” “may” 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 or incorporated by reference in Item 1A “Risk Factors” in this document, supplement, and as otherwise enumerated herein, 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 document. Important factors that could cause our actual results to differ materially from the expectations reflected in the forward-looking statements in this document include those factors described in this document under Item 1A titled “Risk Factors,” including, among others:

 

   

our ability to successfully develop, commercialize and market new products;

 

   

timing and results of pre-clinical or clinical trials on new products;

 

   

our ability to obtain regulatory approval of any of our pipeline products;

 

   

competition for the business of our branded and generic products, and in connection with our acquisition of rights to intellectual property assets;

 

   

significant cash payments we may be required to make to Endo Pharma LLC pursuant to a tax sharing agreement;

 

   

market acceptance of our future products;

 

   

government regulation of the pharmaceutical industry;

 

   

our dependence on a small number of products;

 

   

our dependence on outside manufacturers for the manufacture of our products;

 

   

our dependence on third parties to supply raw materials and to provide services for certain core aspects of our business;

 

   

new regulatory action or lawsuits relating to our use of narcotics in most of our core products;

 

   

our exposure to product liability claims and product recalls and the possibility that we may not be able to adequately insure ourselves;

 

   

our ability to protect our proprietary technology;

 

   

the successful efforts of manufacturers of branded pharmaceuticals to use litigation and legislative and regulatory efforts to limit the use of generics and certain other products;

 

   

our ability to successfully implement our acquisition and in-licensing strategy;

 

   

regulatory or other limits on the availability of controlled substances that constitute the active ingredients of some of our products and products in development;

 

   

the availability of third-party reimbursement for our products;

 

   

the outcome of any pending or future litigation or claims by the government;

 

   

our dependence on sales to a limited number of large pharmacy chains and wholesale drug distributors for a large portion of our total net sales;

 

   

significant litigation expenses to defend or assert patent infringement claims;

 

   

any interruption or failure by our suppliers, distributors and collaboration partners to meet their obligations pursuant to various agreements with us;

 

   

a determination by a regulatory agency that we are engaging in inappropriate sales or marketing activities, including promoting the “off-label” use of our products;

Table of Contents
   

existing suppliers become unavailable or lose their regulatory status as an approved source, causing an inability to obtain required components, raw materials or products on a timely basis or at commercially reasonable prices; and

 

   

the loss of branded product exclusivity periods and related intellectual property.

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 Securities and Exchange Commission (or 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.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(UNAUDITED)

FOR THE THREE MONTHS ENDED MARCH 31, 2007

1. BASIS OF PRESENTATION

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X of the Securities and Exchange Commission for interim financial information. Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements. In the opinion of management, the accompanying condensed consolidated financial statements of Endo Pharmaceuticals Holdings Inc. (the “Company” or “we” or “Endo”) and its subsidiaries, which are unaudited, include all normal and recurring adjustments considered necessary to present fairly the Company’s financial position as of March 31, 2007 and the results of our operations and our cash flows for the periods presented. Operating results for the three-month period ended March 31, 2007 is not necessarily indicative of the results that may be expected for the year ended December 31, 2007.

The accompanying condensed consolidated balance sheet as of December 31, 2006 is derived from the Company’s audited financial statements at that date but does not include all of the information and footnotes required by generally accepted accounting principles for complete 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, 2006 contained in the Company’s Annual Report on

Form 10-K.

2. RECENT ACCOUNTING PRONOUNCEMENTS

In July 2006, the FASB issued FASB Interpretation No. 48 (“FIN 48”), Accounting for Uncertainty in Income Taxes, an interpretation of FASB Statement No. 109, Accounting for Income Taxes. FIN 48 creates a single model to address uncertainty in tax positions. FIN 48 clarifies the accounting for income taxes by prescribing the minimum recognition threshold a tax position is required to meet before being recognized in the financial statements. FIN 48 also provides guidance on derecognition, measurement, classification, interest and penalties, accounting in interim periods, disclosure and transition. In addition, FIN 48 clearly scopes out income taxes from SFAS No. 5, Accounting for Contingencies. FIN 48 is effective for fiscal years beginning after December 15, 2006. We have adopted FIN No. 48 as of January 1, 2007. The adoption resulted in a charge of $2.7 million recorded directly to retained earnings as a cumulative-effect of a change in accounting principle. See Note 12 for further discussion.

In September 2006, the FASB issued SFAS No.157, Fair Value Measurements, which addresses how companies should measure fair value when they are required to use a fair value measure for recognition or disclosure purposes under accounting principles generally accepted in the United States. SFAS No. 157 is effective for fiscal years beginning after November 15, 2007. The Company is currently evaluating the impact of the adoption of this Statement on its financial statements.

In February 2007, the FASB issued SFAS No. 159 (“SFAS 159”) The Fair Value Option for Financial Assets and Financial Liabilities, providing companies with an option to report selected financial assets and liabilities at fair value. This Standard’s objective is to reduce both complexity in accounting for financial instruments and the volatility in earnings caused by measuring related assets and liabilities differently. Generally accepted accounting principles have required different measurement attributes for different assets and liabilities that can create artificial volatility in earnings. SFAS 159 helps to mitigate this type of accounting-induced volatility by enabling companies to report related assets and liabilities at fair value, which would likely reduce the need for companies to comply with detailed rules for hedge accounting. SFAS 159 also establishes presentation and disclosure requirements designed to facilitate comparisons between companies that choose different measurement attributes for similar types of assets and liabilities. This Standard requires companies to provide additional information that will help investors and other users of financial statements to more easily understand the effect of the Company’s choice to use fair value on its earnings. It also requires entities to display the fair value of those assets and liabilities for which the Company has chosen to use fair value on the face of the balance sheet. SFAS 159 is effective for fiscal years beginning after November 15, 2007. The Company is currently evaluating the impact of the adoption of this Statement on its financial statements.

4. LICENSE AND COLLABORATION AGREEMENTS

DURECT Corporation

In April 2007, DURECT and Endo entered into Amendment No. 4 to the Development, Commercialization and Supply License Agreement dated November 8, 2002 (the “DURECT CHRONOGESICTM License Agreement”) relating to the development and commercialization of the CHRONOGESICTM product candidate in the U.S. and Canada. Prior to the present amendment, in addition to other specified termination rights provided to both parties, the DURECT CHRONOGESICTM License Agreement provided Endo with a right to terminate the DURECT CHRONOGESICTM License Agreement starting March 31, 2007 in the event that DURECT had not commenced a specified clinical trial for the CHRONOGESICTM product candidate on or before March 31, 2007, provided that Endo provided DURECT written notice of such termination prior to April 30, 2007. Under Amendment No. 4, the foregoing termination right was amended to provide Endo with the right to terminate the DURECT CHRONOGESICTM License Agreement in the event that (i) DURECT had not delivered to Endo on or before March 31, 2008 a written notice that a human pharmacokinetic trial had been completed with the CHRONOGESICTM product candidate, together with a full study report of the results of the trial or (ii) Endo, determines, in its sole discretion, to terminate the DURECT CHRONOGESICTM License Agreement during the sixty-day period after DURECT’s delivery of such notice, provided that, in each case Endo delivers to DURECT its written notice of termination prior to April 30, 2008. Under Amendment No. 4, Endo shall not be responsible for any development costs for the CHRONOGESICTM product candidate prior to May 1, 2008. Commencing on May 1, 2008, unless the DURECT CHRONOGESICTM License Agreement is earlier terminated by Endo, Endo will fund 50% of the ongoing development costs for the CHRONOGESICTM product candidate in accordance with the terms of the DURECT CHRONOGESICTM License Agreement. A copy of Amendment No. 4 to the Development, Commercialization and Supply License Agreement between DURECT Corporation and Endo is filed hereto as Exhibit 10.42.5 in Part II, Item 6 of this Report. 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 DURECT CHRONOGESIC™ 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™ License Agreement also contains terms and conditions customary for this type of arrangement, including representations, warranties, indemnities and termination rights. The DURECT CHRONOGESIC™ License Agreement generally lasts until the underlying patents on the product expire. With respect to termination rights, the DURECT CHRONOGESIC™ License Agreement permits Endo to terminate its continued participation under a number of circumstances, one of which could require Endo to pay DURECT up to $10.0 million.

SkyePharma, Inc.

In January 2007, following an assessment of the status of DepoDur®, we announced that we notified SkyePharma PLC of our intent to terminate our development and commercialization agreement for this product and, in February 2007, entered into a termination agreement with SkyePharma whereby the Development and Marketing Strategic Alliance Agreement terminated in its entirety on March 31, 2007. In order to provide for the continued commercial support of the DepoDur® product and the transition of such product to SkyePharma on March 31, 2007, Endo continued to provide a number of services and undertake certain activities. Specifically, Endo employed commercially reasonable efforts to maintain and continue all U.S. commercial activities in support of DepoDur® through March 31, 2007, and support and/or undertake the transition of certain Endo functions and activities (including third party activities) to SkyePharma that were useful and necessary for SkyePharma to assume commercial and related responsibilities for DepoDur® in the U.S.

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, $17.7 million of which has been recorded through March 31, 2007 and included in research and development expense. Of this $17.7 million expensed through March 31, 2007, $5.2 million has been recorded during each of the three months ended March 31, 2007 and 2006.

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 the 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 menstrual migraine indication approval milestone and 50% of all royalties to be paid under the license agreement to Vernalis to repay the loan provided that, in each case Endo delivers to Vernalis written notice not less than five (5) business days prior to the due date of any payment. During the three months ended March 31, 2007, royalties payable to Vernalis in the amount of approximately $1.8 million were recorded in selling, general and administrative expenses. We have notified Vernalis that 50% of these royalties will not be paid to Vernalis, but will be used to offset a portion of the unpaid accrued interest on the note receivable. 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. Vernalis has elected to defer the payment of the first five semi-annual interest amounts otherwise due January 31 and July 31 totaling approximately $6.4 million. We expect to offset 50% of future royalty payment obligations to Vernalis against these interest payment deferrals and consequently we have reclassified a portion of the accrued interest on the note receivable to other current assets.

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, net.

8. STOCK-BASED COMPENSATION

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 reserved 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 are issued. Endo Pharma LLC is a limited liability company that is no longer affiliated with the Company and in which affiliates of Kelso & Company have a controlling interest. Exercise of these stock options has not and will not result in the issuance of additional shares in the Company and does not dilute the ownership interests of our public stockholders.

Pursuant to the Company’s merger with Algos Pharmaceutical Corporation (Algos) 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 reserved 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 have been or will be issued as a result of the exercise of these stock options, 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 has not and will not result in the issuance of additional shares in the Company and does not dilute the ownership interests of our public stockholders.

Endo Pharmaceuticals Holdings Inc. 2000 and 2004 Stock Incentive Plans

On August 11, 2000, we established the Endo Pharmaceuticals Holdings Inc. 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 Stock Incentive 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. The Company has approved a 2007 Stock Incentive Plan and will adopt the plan subject to shareholder approval at the Company’s annual meeting of stockholders to be held on May 30, 2007. The maximum number of shares of Company stock reserved for issuance under the 2007 Stock Incentive Plan will be seven million (7,000,000) shares (subject to adjustment for certain transactions), but in no event may the total number of shares of Company stock subject to awards awarded to any one Participant during any tax year of the Company, exceed seven hundred fifty thousand (750,000) shares (subject to adjustment for certain transactions). As of March 31, 2007, both stock options and restricted stock have been awarded under the 2000 and 2004 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 the ownership interests of our public stockholders. In March 2007, restricted stock was granted to non-employee directors of the Company as part of their annual stock compensation award. This restricted stock will vest ratably over a two-year vesting period (50% on the first anniversary of the grant date and the remaining 50% on the second anniversary of the grant date).

Stock-Based Compensation

The Company accounts for its stock-based compensation plans in accordance with Statement of Financial Accounting Standards (“SFAS”) No. 123(R), Share-Based Payment (SFAS 123R). Under SFAS 123R, all stock-based compensation cost is measured at the grant date, based on the estimated fair value of the award, and is recognized as an expense in the income statement over the requisite service period.

During the three months ended March 31, 2007 and 2006, the Company recognized stock-based compensation expense of $3.1 million and $2.3 million, respectively. Presented below is the allocation of stock-based compensation as recorded in our Condensed Consolidated Statements of Operations for the three months ended March 31, 2007 and 2006 (in thousands).

Stock Options

For all of the Company’s stock-based compensation plans, the fair value of each option grant was estimated at the date of grant using the Black-Scholes option-pricing model. Black-Scholes utilizes assumptions related to volatility, the risk-free interest rate, the dividend yield (which is assumed to be zero, as the Company has not paid cash dividends to date and does not currently expect to pay cash dividends) and the expected term of the option. Expected volatilities utilized in the model are based mainly on the historical volatility of the Company’s stock price over a period commensurate with the expected life of the share option as well as other factors. The risk-free interest rate is derived from the U.S. Treasury yield curve in effect at the time of grant. We estimate the expected term of options granted based on our historical experience with our employees’ exercise of stock options and other factors. .

As of March 31, 2007, there was no remaining unrecognized compensation cost related to non-vested stock options granted pursuant to the Endo Pharma LLC 1997 Stock Option Plans and the Endo Pharma LLC 2000 Supplemental Stock Option Plans.

Restricted Stock

During the three months ended March 31, 2007, the Company granted restricted stock awards to non-employee directors of the Company as part of their annual stock compensation award. This restricted stock will vest ratably over a two-year vesting period (50% on the first anniversary of the grant date and the remaining 50% on the second anniversary of the grant date). We recognize expense for our restricted stock using the straight-line method over the requisite service period. The total value of compensation expense for restricted stock is equal to the closing price of Endo shares on the date of grant.

9. RELATED PARTY TRANSACTIONS

Tax Sharing Agreement. On July 14, 2000, Endo Pharma LLC was formed in connection with our merger with Algos Pharmaceutical Corporation (Algos) 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 held approximately 15% of our common stock at December 31, 2005, but less than 1% of our common stock as of March 31, 2007, in which affiliates of Kelso & Company and certain current and former 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 have been and will be delivered. Because Endo Pharma LLC, and not us, has been and 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 March 31, 2007, approximately 36 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 March 31, 2007, approximately $773 million), which is estimated to result in a tax benefit amount of approximately $298 million. Under the tax sharing agreement, we are required to pay this $298 million, $272 million of which has already been paid as of March 31, 2007, 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. Additionally, as part of the tax sharing agreement, Endo Pharma LLC will reimburse us for the after-tax employer payroll taxes paid by us as a result of the exercise of the 36 million options discussed above. We have paid approximately $11 million in employer payroll taxes, of which Endo Pharma LLC will reimburse us for approximately $7 million, which represents the after-tax employer payroll tax paid by us for the periods from 2001 through March 31, 2007. As of March 31, 2007, our net liability due to Endo Pharma LLC is approximately $18.7 million. 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.

During the three months ended March 31, 2007, approximately 19,000 shares underlying stock options granted under the Endo Pharma LLC stock option plans were exercised. Since we expect the attributable compensation charge deductions to be usable to reduce our taxes in 2007, we are obligated, under our amended tax sharing agreement, to pay to Endo Pharma LLC an additional tax benefit amount of approximately $0.2 million, which is included in our net liability due to Endo Pharma LLC referred to above. Fifty percent of the estimated tax benefit amount attributable to these exercises and any additional tax benefits attributable to the exercise of stock options granted under the Endo Pharma LLC stock option plans in 2007 will be due within 15 business days of the date we receive an opinion on our final audited 2007 financial statements from our independent registered public accounting firm, and the remaining tax benefit amount attributable to 2007 is due within 30 business days of the date on which we file our 2007 tax return with the Internal Revenue Service.

As of March 31, 2007, there were 55,968 stock options, which expire in August 2007, remaining to be exercised under the Endo Pharma LLC stock option plans. Using a weighted average exercise price of $2.42 per share and an assumed tax rate of 38.25%, if all of these remaining stock options under the Endo Pharma LLC stock option plans were vested and exercised, and assuming the price of our common stock was $29.40 per share, the closing price on March 30, 2007, we would generally be able to deduct, for income tax purposes, compensation of approximately $1.5 million, which could result in a tax benefit amount of approximately $0.6 million payable to Endo Pharma LLC in 2008. This would represent the final tax sharing payment due to Endo Pharma LLC.

As of March 31, 2007, there were no options remaining to be granted under the Endo Pharma LLC stock option plans.

Executive Compensation. In March 2006, Endo Pharma LLC advised our Board of Directors that it intended to pay a one-time cash bonus to each of Mr. Peter Lankau, our President and Chief Executive Officer, Ms. Caroline Manogue, our Executive Vice President, Chief Legal Officer and Secretary, and Mr. Jeffrey Black, our former Executive Vice President, Chief Financial Officer and Treasurer in the amount of $3 million, $6 million and $10 million, respectively, in recognition of their significant contributions to our success. These bonus payments have been recorded in selling, general and administrative expenses during the year ended December 31, 2006. These payments were made by the Company in April 2006 and repaid to us by Endo Pharma LLC in the third quarter of 2006 with interest. In addition, only a portion of these bonus payments will be deductible for federal and state income tax purposes. We are not required to pay nor will we pay to Endo Pharma LLC the amount of any of the tax benefits related to these bonus payments pursuant to the tax sharing agreement between us and Endo Pharma LLC. These bonuses will be funded entirely by Endo Pharma LLC, with no contribution by us and they have been treated as a capital contribution by Endo Pharma LLC.

Endo Pharma LLC also informed us that, in connection with its eventual winding-up, it would make a special allocation to Ms. Carol Ammon, our Chairman of the Board and former Chief Executive Officer, of approximately $22 million, with all or a portion of Ms. Ammon’s payment being satisfied by granting to her the remaining unallocated Endo Pharma LLC stock options of approximately 0.8 million shares under the Endo Pharma LLC stock option plans. This amount has been recorded in selling, general and administrative expenses during the year ended December 31, 2006 and as a capital contribution by Endo Pharma LLC. This grant of options to Ms. Ammon was made during the fourth quarter of 2006. The 0.8 million options were granted by Endo Pharma LLC to Ms. Ammon in the fourth quarter of 2006, as described above, at an exercise price of $2.42 per share. Therefore, approximately $20 million of the approximately $22 million recorded in the first quarter of 2006 was reclassified as a stock compensation expense representing the fair value of the option on the date of grant. These options were immediately vested and exercised by Ms. Ammon and the resulting compensation charge deduction of approximately $19 million and the resulting tax sharing obligation to Endo Pharma LLC is included in our tax sharing liability discussed above. Endo Pharma LLC intends to pay the remaining $2 million to Ms. Ammon in 2007.

Related Party Matters. Robert Ammon, the brother of our current Chairman and former Chief Executive Officer, is employed by the Company as a senior national account executive and has been since the company’s founding as a private company in 1997. It is expected that his 2007 total compensation, including base salary, incentive compensation, long-term incentive compensation and all benefits (including health benefits), will be in excess of $120,000 but will not exceed $250,000. Marisa Lankau, the daughter of our President and Chief Executive Officer, is employed by the Company as a sales representative and has been since 2006. It is expected that her 2007 total compensation, including base salary, incentive compensation, long-term incentive compensation and all benefits (including health benefits), may be in excess of $120,000 but will not exceed $125,000.

10. COMMITMENTS AND CONTINGENCIES

Manufacturing, Supply and Other Service Agreements We contract with various third party manufacturers and suppliers to provide us with our raw materials used in our products and finished goods. Our most significant agreements are with Novartis Consumer Health, Inc., Teikoku Seiyaku Co., Ltd., and Mallinckrodt Inc. If for any reason we are unable to obtain sufficient quantities of any of the finished goods or raw materials or components required for our products, this may have a material adverse effect on our business, financial condition and results of operations.

Novartis Consumer Health, Inc.

On May 3, 2001, we entered into a long-term manufacturing and development agreement with Novartis Consumer Health, Inc. whereby Novartis has agreed to manufacture certain of our commercial products and products in development. We are required to purchase, on an annual basis, a minimum amount of product from Novartis. The purchase price per product is equal to a predetermined amount per unit, subject to periodic adjustments. This agreement had a five-year term, with automatic five-year renewals thereafter. In August 2005, we extended this agreement until 2011. We are required to purchase a minimum of approximately $17 million per year through December 31, 2009. Either party may terminate this agreement on three-years’ notice, effective at any time after the initial five-year term. Either party may also terminate this agreement on account of a material breach by the other.

Teikoku Seiyaku Co., Ltd.

Under the terms of this agreement, Teikoku, a Japanese manufacturer, manufactures Lidoderm® at its Japanese facility for commercial sale by us in the United States. We also have an option to extend the supply area to other territories. On April 24, 2007, we amended this agreement. The material components of the Amended Agreement are as follows:

 

   

Teikoku has granted to us an exclusive (even as to Teikoku) license to certain intellectual property rights to use, sell or offer for sale (but not make or have made) the Product (as defined in the amended agreement).

 

   

We have agreed to purchase a certain number of patches per year for each year in the remaining term of the amended agreement.

 

   

Teikoku has agreed to fix the price of the Product for a period time after which the price will be adjusted at future dates certain based on a price index defined in the amendment agreement.

 

   

Following cessation of our obligation to pay royalties to Hind Healthcare Inc. (“Hind”) under the Sole and Exclusive License Agreement dated as of November 23, 1998, as amended, between Hind and Endo, we will pay to Teikoku annual royalties based on our annual net sales of the Product.

 

   

The amended agreement will expire on December 31, 2021, unless terminated in accordance with its terms. After December 31, 2021, the amended agreement shall be automatically renewed on the first day of January each year unless (i) we and Teikoku agree to terminate the amended agreement upon mutual written agreement or (ii) either we or Teikoku terminates the amended agreement with 180-day written notice to the other party, which notice shall not in any event be effective prior to July 1, 2022.

Mallinckrodt Inc.

Under the terms of this agreement, Mallinckrodt manufactures and supplies to us narcotic active drug substances, in bulk form, and raw materials for inclusion in our controlled substance pharmaceutical products. We are required to purchase a fixed percentage of our annual requirements of each narcotic active drug substance from Mallinckrodt. The purchase price for these substances is equal to a fixed amount, adjusted on an annual basis. The initial term of this agreement is July 1, 1998 until June 30, 2013, with an automatic renewal provision for unlimited successive one-year periods. Either party may terminate this agreement for a material breach.

General

In addition to the manufacturing and supply agreements described above, we have agreements with (1) UPS Supply Chain Solutions, Inc. (f/d/b/a Livingston Healthcare Services, Inc.) for customer service support, warehouse and distribution services and certain financial functions that expires in 2010, (2) Kunitz and Associates Inc. for assistance with adverse event reporting and (3) PPD Development, LP for clinical development services, business development support and medical information services. Although we have no reason to believe that these agreements will not be honored, failure by any of these third parties to honor their contractual obligations may have a materially adverse effect on our business, financial condition and results of operations.

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 March 31, 2007 and 2006, we recorded $17.1 million and $13.8 million, respectively, for these royalties to Hind, which at March 31, 2007 and 2006 has been recorded as a royalty payable and included in accounts payable in the accompanying balance sheet.

Penwest Pharmaceuticals

In January 2007, the Company and Penwest entered into an amendment (the 2007 Amendment) to the 2002 amended and restated strategic alliance agreement between the parties (the 2002 Agreement). Under the terms of the 2007 Amendment, Endo and Penwest agreed to restructure the 2002 Agreement to provide that royalties payable to Penwest for U.S. sales of Opana® ER will be calculated based on net sales of the product rather than on operating profit, and to change certain other provisions of the 2002 Agreement. The 2007 Amendment also resolves the parties’ ongoing disagreement with regard to sharing of marketing expenses during the period prior to when Opana® ER reaches profitability. The key financial terms of the 2007 Amendment are summarized as follows:

 

   

With respect to U.S. sales of Opana® ER, Endo’s royalty payments to Penwest will be calculated starting at 22% of annual net sales of the product, and, based on agreed-upon levels of annual net sales achieved, the royalty rate can increase to a maximum of 30%.

 

   

No royalty payments will be due to Penwest for the first $41 million of royalties that would otherwise have been payable beginning from the time of the product launch in July 2006.

 

   

Penwest is entitled to receive milestone payments of up to $90 million based upon the achievement of certain agreed-upon annual sales thresholds.

 

   

In 2003, Penwest opted out of funding development costs for Opana® ER. Under the 2007 Amendment, the parties have agreed that Penwest’s share of these unfunded development costs will be fixed at $28 million and will be recouped by Endo through a temporary 50% reduction in royalties payable to Penwest. This temporary reduction in royalties will not apply until the $41 million royalty threshold referred to above has been met.

Royalties payable to Penwest through March 31, 2007 would have amounted to $6.1 million if not for the $41 million royalty threshold referred to above (prior to which Endo does not owe Penwest any royalties).

DURECT Corporation

In April 2007, DURECT and Endo entered into Amendment No. 4 to the Development, Commercialization and Supply License Agreement dated November 8, 2002 (the “DURECT CHRONOGESICTM License Agreement”). Under Amendment No. 4, Endo shall not be responsible for any development costs for the CHRONOGESICTM product candidate prior to May 1, 2008. Commencing on May 1, 2008, unless the DURECT CHRONOGESICTM License Agreement is earlier terminated by Endo, Endo will fund 50% of the ongoing development costs for the CHRONOGESICTM product candidate in accordance with the terms of the DURECT CHRONOGESICTM License Agreement. A copy of Amendment No. 4 to the Development, Commercialization and Supply License Agreement between DURECT Corporation and Endo is filed hereto as Exhibit 10.42.5 in Part II, Item 6 of this Report. 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 DURECT CHRONOGESIC™ License Agreement could total up to $52.0 million. Endo and DURECT will share profits equally, based on projected financial performance of CHRONOGESIC™. With respect to termination rights, the DURECT CHRONOGESIC™ License Agreement permits Endo to terminate its continued participation under a number of circumstances, one of which could require Endo to pay DURECT up to $10.0 million.

In addition, in March 2005, 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”). 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, and are subject to potential additional payment requirements of up to 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. 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.

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 the license agreement with Vernalis, we could be required to make a $40 million milestone payment upon FDA approval for the menstrual migraine indication (MM). In addition, Vernalis could 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® beginning on January 1, 2007. We can terminate the license agreement under certain circumstances, including upon one years’ written notice. During the three months ended March 31, 2007, royalties payable to Vernalis in the amount of approximately $1.8 million were recorded in selling, general and administrative expenses. We have notified Vernalis that 50% of those royalties, or approximately $900,000 will not be paid to Vernalis, but will be used to offset a portion of the unpaid accrued interest on the note receivable (See Note 6).

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, $17.7 million of which has been recorded through March 31, 2007 and included in research and development expense. Of this $17.7 million expensed through March 31, 2007, $5.2 million has been recorded during each of the three months ended March 31, 2007 and 2006. 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. 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 $750,000.

Zars Pharma

Under the terms of the agreement, we may be required to make additional payments of up to approximately $19 million upon achievement of certain commercial milestones. We will also pay ZARS royalties on net sales of SyneraTM.

ProEthic Pharmaceuticals, Inc.

Under the terms of the agreement, in March 2005, we paid a $10 million upfront fee that was expensed as research and development during the year ended December 31, 2005 for the ketoprofen patch. During 2006, we made an additional $5 million milestone payment that has been expensed as research and development. We could be required to make additional payments of approximately $8 million upon the achievement of certain regulatory and other milestones. We will also pay royalties on net sales of the ketoprofen patch. We can terminate the agreement at any time upon no more than ninety 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. During the three months ended March 31, 2007, we invested an additional $2.8 million in this partnership, bringing our cumulative cash investment to $5.5 million as of March 31, 2007. We are accounting for this investment utilizing the equity method.

Employment Agreements

We have entered into employment agreements with certain members of management.

Research Contracts

In addition to our agreement with PPD Development, LP, 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 collaboration agreements with third parties for the development of pain management and other products. Potential milestone payments pursuant to these contracts could total up to approximately $6 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 March 31, 2007.

Department of Health and Human Services Subpoena.

In January 2007, the Company received a subpoena issued by the United States Department of Health and Human Services, Office of Inspector General (OIG). The subpoena requests documents relating to Lidoderm® (lidocaine patch 5%), focused primarily on the sale, marketing and promotion of Lidoderm®. The Company is cooperating with the government to provide the requested documents. At this time, the Company cannot predict or determine the outcome of the above matter or reasonably estimate the amount or range of amounts of fines or penalties, if any, that might result from an adverse outcome.

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) 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’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’s OxyContin®, 40mg strength, challenged the listed patents for OxyContin® 40mg tablets. On March 13, 2001 and August 30, 2001, Purdue filed two more suits for infringement of the same patents against us and EPI in the Southern District of New York, in response to EPI’s ANDA amendments adding bioequivalent versions of the 10, 20 and 80 mg strengths of OxyContin®. In each of the three cases, EPI pleaded counterclaims that the patents asserted by Purdue are invalid, unenforceable and/or not infringed by EPI’s formulation of oxycodone hydrochloride extended-release tablets, and that Purdue violated antitrust laws by enforcing fraudulently procured patents.

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 dismissed the patent claims against us and EPI, declared the patents invalid, and enjoined Purdue from further enforcement of the patents. On June 7, 2005, the U.S. Court of Appeals for the Federal Circuit in Washington, D.C. affirmed the district court’s decision that, while Endo’s oxycodone extended-release tablets infringe the Purdue patents, the patents are unenforceable. On June 21, 2005, Purdue filed a petition with the Federal Circuit seeking rehearing of the appeal.

Table of Contents

On February 1, 2006, the Federal Circuit granted Purdue’s motion for rehearing, vacated the June 7, 2005 decision of the district court, and remanded the case to the district court for further proceedings. The Federal Circuit’s decision on rehearing directed the district court to give further consideration to its previous finding of unenforceability due to inequitable conduct. The Federal Circuit also affirmed the district court’s finding that EPI’s oxycodone extended-release tablets infringe the Purdue patents.

Following the remand, we entered into settlement discussions with Purdue. On August 28, 2006, we executed a settlement agreement with Purdue pursuant to which we agreed to cease selling our oxycodone extended-release products on December 31, 2006. We and EPI, as well as our manufacturers, distributors, purchasers, and patients, are released from all liability for infringement of Purdue’s patents in connection with EPI’s prior and future sales of these products. Though the settlement agreement has been submitted to the U.S. Federal Trade Commission and the Antitrust Division of the Department of Justice as required by statute, the release will survive unless overturned by a court order. On October 6, 2006, the district court entered a Consent Judgment, the effect of which is to conclude the litigation in accordance with the terms of the settlement agreement.

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.

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 are pending in MDL 1456 and have been consolidated into one consolidated complaint: City of New York v. Abbott Laboratories, Inc., et al.; County of Albany v.

There is a previously reported case pending in the Circuit Court of Montgomery County, Alabama against EPI and numerous other pharmaceutical companies: State of Alabama v. Abbott Laboratories, Inc., et al.

There is a previously reported case against EPI and numerous other pharmaceutical companies, State of Mississippi v. Abbott Laboratories, Inc., et al., originally filed in the Chancery Court of Hinds County, Mississippi. The State of Mississippi offered to enter an agreed order of dismissal with respect to Endo, and Endo filed a notice of acceptance of that offer in Hinds County Chancery Court. The case was removed to federal court and transferred to MDL 1456, where it is currently pending. Endo is not listed as a party to the suit currently pending in 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 and results of operations.

12. Income Taxes

On January 1, 2007, the Company adopted FASB Interpretation No. 48, Accounting for Uncertainty in Income Taxes (FIN 48), which became effective for fiscal years beginning after December 15, 2006. FIN 48 creates a single model to address uncertainty in tax positions and clarifies the accounting for income taxes by prescribing the minimum recognition threshold a tax position is required to meet before being recognized in the financial statements. The provisions of FIN 48 apply to all material tax positions in all taxing jurisdictions for all open tax years. FIN 48 establishes a two-step process for evaluating tax positions. Step 1 – Recognition, requires the Company to determine whether a tax position, based solely on its technical merits, has a likelihood of more than 50 percent (“more-likely-than-not”) that the tax position taken will be sustained upon examination. Step 2 – Measurement, which is only addressed if Step 1 has been satisfied, requires the Company to measure the tax benefit as the largest amount of benefit, determined on a cumulative probability basis that is more- likely-than-not to be realized upon ultimate settlement.

The Company files income tax returns in the U.S. federal jurisdiction and in various state and local jurisdictions. In general, the Company is no longer subject to U.S. federal, state and local income tax examinations by tax authorities for years before 2002.

Table of Contents

Under FIN 48 we determined that certain income tax positions did not meet the more-likely-than-not recognition threshold and, therefore, required a 100% reserve. Accordingly, as of January 1, 2007, the Company recorded a non-cash cumulative transition charge of approximately $2.7 million, recorded as a reduction to beginning retained earnings and we have not restated any prior period amounts. The Company records accrued interest and penalties related to unrecognized tax benefits in income tax expense. As of January 1, 2007, the company has accrued $2.2 million in interest and penalties. The total amount of unrecognized tax benefits as of January 1, 2007 was $6.4 million. There have been no material changes to the unrecognized tax benefits or accrued interest and penalties as of March 31, 2007. The total amount of unrecognized tax benefits that, if recognized, would affect the effective tax rate is approximately $6.4 million.

It is expected that the amount of unrecognized tax benefits will change during the next twelve months; however, the Company does not anticipate any adjustments which would lead to a material impact on our results of operations or our financial position.

13. Acquisitions

RxKinetix, Inc.

On October 12, 2006, the Company acquired all of the outstanding common stock of privately held RxKinetix, Inc. RxKinetix specializes in developing new therapeutics focused on improving the quality of life for patients being treated for cancer. RxKinetix’s most advanced product, now named EN 3285, is currently in clinical Phase II for the prevention of oral mucositis, a painful, debilitating and often dose-limiting side effect that afflicts many patients being treated for cancer with radiation and/or chemotherapy. RxKinetix is a development stage company and therefore was accounted for as an asset acquisition. The results of operations for RxKinetix have been included in our consolidated financial statements beginning on the acquisition date.

The purchase price of RxKinetix, as of the acquisition date, was $20.5 million which was funded from our existing cash on hand. Additional contingent cash purchase consideration of up to $95 million may become due upon the achievement of certain clinical and regulatory milestones. The Company has allocated the purchase price to the RxKinetix assets acquired and liabilities assumed at their estimated fair values, based on a number of factors, including the use of an independent appraisal. Estimated fair values were determined through the use of a discounted cash flow analysis using market participant assumptions. Of the purchase price, approximately $26.0 million has been allocated to tangible and intangible assets to be used in research and development activities and those assets have been written-off to purchased in-process research and development, as of the acquisition date. The excess of fair value of the net assets acquired compared to the amount paid as of the acquisition date has been reflected as “estimated amount due seller” in accordance with SFAS No. 141, Business Combinations. Any contingent consideration paid in the future will be first applied to reduce the amount recorded as estimated amount due seller, and thereafter to the net assets acquired based on their relative fair values. Our preliminary purchase allocation is subject to revision; subsequent revisions, if any, are not expected to be material. At March 31, 2007, we reclassified to a current liability, $15 million of the “estimated amount due seller” which at December 31, 2006 was classified, in its entirety, as a non-current liability. The current portion of the “estimated amount due seller” is payable upon the achievement of certain clinical and regulatory milestones under the terms of the RxKinetix acquisition. There has not been any material change in the estimated fair values assigned to the assets acquired and liabilities assumed since the date of acquisition.

The following table summarizes the estimated fair values of the assets acquired and liabilities assumed as of the date of acquisition (in thousands):

Table of Contents

As a result of our acquisition of RxKinetix, Inc., we acquired one significant in-process research and development project, known as EN 3285, a topical oral rinse with the active ingredient formulated in its proprietary ProGelz® drug delivery platform. All of the purchased in-process research and development value from this transaction was assigned to EN 3285 since the other products, as of the acquisition date, were very early stage and did not meet the criteria to be recognized as assets. As of the acquisition date, EN 3285 was in clinical Phase II for the prevention of oral mucositis, painful mouth sores that often occur in cancer patients undergoing radiation and chemotherapeutic treatment. During the course of high-dose cancer therapy and bone marrow transplantation, patients often develop painful and debilitating oral inflammation, or mucositis, in the mouth. The resulting weight loss, dehydration and, in some cases, infection often lead to dose-limitation of chemotherapy and radiation therapy, and contribute considerably to cancer and transplant-related morbidity and mortality. Further, these side effects add to related medical costs by prolonging hospital stays, increasing antibiotic, fluid, and analgesic use, and requiring patients to receive parenteral nutritional support. Of the estimated 800,000 patients treated for cancer in the United States, as many as 400,000 may develop the debilitating complications of oral mucositis as a result of their treatment. RxKinetix also had other products in early- stage development based on the ProGelz® technology. We plan to conduct additional Phase II trials of EN 3285 to continue to characterize the clinical profile of the product in the intended patient population — head and neck cancer patients undergoing combination treatment of radiation and chemotherapy.

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

The following Management’s Discussion and Analysis of Financial Condition and Results of Operations describes the principal factors affecting the results of operations, liquidity and capital resources, and critical accounting policies and estimates of Endo. This discussion should be read in conjunction with the accompanying quarterly unaudited condensed consolidated financial statements and our Annual Report on Form 10-K, for the year ended December 31, 2006 (“Annual Report”). Our Annual Report includes additional information about our significant accounting policies, practices and the transactions that underlie our financial results, as well as a detailed discussion of the most significant risks and uncertainties associated with our financial and operating results. 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 are a specialty pharmaceutical company with market leadership in pain management. We are engaged in the research, development, sale and marketing of branded and generic prescription pharmaceuticals used primarily to treat and manage pain. According to Wolters Kluwer Health data, the total U.S. market for pain management pharmaceuticals, excluding over-the-counter products, totaled $19.7 billion in 2006. This represents an approximately 8% compounded annual growth rate since 2002. Our primary area of focus within this market is analgesics and, specifically, opioid analgesics. In 2006, analgesics were the fourth most prescribed medication in the United States with over 260 million prescriptions written for this classification. Opioid analgesics is a segment that comprised approximately 80% of the analgesics prescriptions for 2006. Total U.S. sales for the opioid analgesic segment were $7.3 billion in 2006, representing a compounded annual growth rate of 8% since 2002.

We have a portfolio of branded products that includes established brand names such as Lidoderm®, Percocet®, Frova® and Percodan®, as well as three newly launched products in 2006 – Opana® ER, Opana® and SyneraTM. Branded products comprised approximately 80% of our net sales in 2006, with 62% of our net sales coming from Lidoderm®. Our non-branded generic portfolio, which accounted for 20% of net sales in 2006, currently consists of products primarily focused in pain management, with our generic oxycodone extended-release tablets accounting for 6% of our net sales in 2006. We focus on selective generics that have one or more barriers to market entry, such as complex formulation, regulatory or legal challenges or difficulty in raw material sourcing.

We have established research and development expertise in analgesics and devote significant resources to this effort so that we can maintain and develop our product pipeline. Our late-stage branded product pipeline includes one filed supplemental New Drug Application (sNDA), two products in Phase III clinical trials and three products in Phase II clinical trials.

We enhance our financial flexibility by outsourcing certain of our functions, including manufacturing and distribution. Currently, our primary suppliers of contract manufacturing services are Novartis Consumer Health, Inc. and Teikoku Seiyaku Co., Ltd.

Through a dedicated sales force of approximately 590 sales representatives in the United States, we market our branded pharmaceutical products to high-prescribing physicians in pain management, neurology, surgery, anesthesiology, oncology and primary care. Our sales force also targets retail pharmacies and other healthcare professionals throughout the United States.

On a continuous basis, we evaluate and, where appropriate, pursue acquisition opportunities on terms we consider favorable. In particular, we look to continue to enhance our product line by acquiring or licensing rights to additional products and compounds and therefore regularly evaluate selective acquisition and license opportunities. Such acquisitions or licenses may be carried out through the purchase of assets, joint ventures and licenses or by acquiring other companies. Currently, however, we have no binding commitment related to any acquisitions.

Our wholly-owned subsidiary, Endo Pharmaceuticals Inc. (EPI), commenced operations in 1997 by acquiring certain pharmaceutical products, related rights and assets of The DuPont Merck Pharmaceutical Company, which subsequently became DuPont Pharmaceuticals Company and was thereafter purchased by the Bristol-Myers Squibb Pharma Company in 2001. Endo Pharmaceuticals Inc. was formed by some members of the then-existing management of DuPont Merck and an affiliate of Kelso & Company who were also parties to the purchase agreement, under which we acquired these initial assets.

Recent Developments

In April 2007, the Company and Teikoku Seiyaku Co., Ltd. / Teikoku Pharma USA, Inc. (collectively, “Teikoku”) amended their Supply and Manufacturing Agreement dated as of November 23, 1998 by and between Endo and Teikoku, pursuant to which Teikoku manufactures and supplies Lidoderm® (lidocaine patch 5%) (the “Product”) to Endo. This amendment is referred to as the Amended Agreement. The material components of the Amended Agreement are as follows:

 

   

Teikoku has granted to us an exclusive (even as to Teikoku) license to certain intellectual property rights to use, sell or offer for sale (but not make or have made) the Product (as defined in the amended agreement).

 

23


Table of Contents
   

We have agreed to purchase a certain number of patches per year for each year in the remaining term of the amended agreement.

 

   

Teikoku has agreed to fix the price of the Product for a period time after which the price will be adjusted at future dates certain based on a price index defined in the amendment agreement.

 

   

Following cessation of our obligation to pay royalties to Hind Healthcare Inc. (“Hind”) under the Sole and Exclusive License Agreement dated as of November 23, 1998, as amended, between Hind and Endo, we will pay to Teikoku annual royalties based on our annual net sales of the Product.

 

   

The amended agreement will expire on December 31, 2021, unless terminated in accordance with its terms. After December 31, 2021, the amended agreement shall be automatically renewed on the first day of January each year unless (i) we and Teikoku agree to terminate the amended agreement upon mutual written agreement or (ii) either we or Teikoku terminates the amended agreement with 180-day written notice to the other party, which notice shall not in any event be effective prior to July 1, 2022.

In April 2007, we announced that Carol A. Ammon, Founder and Chairman of the Board, has informed the company that she has decided to retire, effective May 30, 2007, from her position as Endo’s Chairman to devote more time to her philanthropic activities, and accordingly, will not run for re-election to the company’s board of directors. The Company also announced that Roger H. Kimmel, an independent director of Endo since 2000, has been appointed by the Board to serve as Chairman, effective May 30, 2007.

In April 2007, the Company announced that it received notice from Anesiva, Inc., advising of the filing of a New Drug Application (NDA) under 21 U.S.C. § 355(b)(2)(A)(iv) (also referred to as Section 505 (b)(2)(A)(iv) of the Federal Food, Drug and Cosmetic Act) for its ZingoTM Dermal PowderJect Lidocaine HCl topical powder and referring to the patents that cover the method of use and formulation of Endo’s lidocaine-containing topical patch products, Lidoderm® and SyneraTM. Section 505(b)(2) does not allow for automatic generic substitution of these prescription products for any other products. If approved, Endo believes that ZingoTM will not be a generic to, nor will it compete with, Lidoderm® because of ZingoTM’s indication and formulation. Anesiva’s notice stated that ZingoTM’s proposed indication is for preventing or reducing pain associated with blood draws and intravenous placements. Unlike Lidoderm®, ZingoTM is not a topical patch. However, Endo believes that, although ZingoTM would not be a substitutable generic to SyneraTM and uses a different delivery mechanism, ZingoTM may compete with SyneraTM because their indications may be similar. Endo will continue to evaluate these notices. According to Anesiva’s notice letter, Zingo’s injection device drives lidocaine powder into the skin surface using accelerated inert gas particles. An NDA for ZingoTM was filed in late 2006 and accepted for filing in January 2007.

In March 2007, we along with Vernalis plc announced that the FDA informed the companies that it will require an additional three months to review Endo’s previously submitted Supplemental New Drug Application (sNDA) for Frova(R) (frovatriptan succinate) 2.5 mg tablets for the expanded indication of short-term prevention of menstrual migraine (MM). The FDA now anticipates completing its review of this application on or before August 19, 2007. As previously disclosed, the original PDUFA (Prescription Drug User Fee Act) review date was May 19, 2007. The companies noted that the FDA’s request relates solely to the presentation of the data and not its content and that no additional data have been requested.

In January 2007, the Company and Penwest entered into an amendment (the 2007 Amendment) to the 2002 amended and restated strategic alliance agreement between the parties (the 2002 Agreement). Under the terms of the 2007 Amendment, Endo and Penwest agreed to restructure the 2002 Agreement to provide that royalties payable to Penwest for U.S. sales of Opana® ER will be calculated based on net sales of the product rather than on operating profit, and to change certain other provisions of the 2002 Agreement. The 2007 Amendment also resolves the parties’ ongoing disagreement with regard to sharing of marketing expenses during the period prior to when Opana® ER reaches profitability. The key financial terms of the 2007 Amendment are summarized as follows:

 

   

With respect to U.S. sales of Opana® ER, Endo’s royalty payments to Penwest will be calculated starting at 22% of annual net sales of the product, and, based on agreed-upon levels of annual net sales achieved, the royalty rate can increase to a maximum of 30%.

No royalty payments will be due to Penwest for the first $41 million of royalties that would otherwise have been payable beginning from the time of the product launch in July 2006.

 

   

Penwest is entitled to receive milestone payments of up to $90 million based upon the achievement of certain agreed-upon annual sales thresholds.

 

   

In 2003, Penwest opted out of funding development costs for Opana® ER. Under the 2007 Amendment, the parties have agreed that Penwest’s share of these unfunded development costs will be fixed at $28 million and will be recouped by Endo through a temporary 50% reduction in royalties payable to Penwest. This temporary reduction in royalties will not apply until the $41 million royalty threshold referred to above has been met

In January 2007, following an assessment of the status of DepoDur®, we announced that we notified SkyePharma PLC of our intent to terminate our development and commercialization agreement for this product and, in February 2007, entered into a termination agreement with SkyePharma whereby the Development and Marketing Strategic Alliance Agreement was terminated in its entirety on March 31, 2007. In order to provide for the continued commercial support of the DepoDur® product and the transition of such product to SkyePharma on March 31, 2007, Endo continued to provide a number of services and undertake certain activities. Specifically, Endo employed commercially reasonable efforts to maintain and continue all U.S. commercial activities in support of DepoDur® through March 31, 2007 and support and/or undertake the transition of certain Endo functions and activities (including third party activities) to SkyePharma that are useful and necessary for SkyePharma to assume commercial and related responsibilities for DepoDur® in the U.S.

In January 2007, the Company received a subpoena issued by the United States Department of Health and Human Services, Office of Inspector General (OIG). The subpoena requests documents relating to Lidoderm® (lidocaine patch 5%), focused primarily on the sale, marketing and promotion of Lidoderm®. The Company is cooperating with the government to provide the requested documents.

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 revenue recognition and sales deductions for estimated chargebacks, rebates, sales incentives and allowances, certain royalties, distribution service fees, 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, the potential impairment of goodwill and other intangible assets, income taxes, contingencies and stock-based compensation. Some of these judgments can be subjective and complex, and, consequently, actual results may differ from these estimates. For any given individual estimate or assumption made by us, there may also be other estimates or assumptions that are 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:

Revenue Recognition

Our net sales consist of revenues from sales of our pharmaceutical products, less estimates for chargebacks, rebates, sales incentives and allowances, certain royalties, distribution service fees, returns and losses. We recognize revenue for product sales when title and risk of loss has passed to the customer, which is typically upon delivery to the customer, when estimated provisions for chargebacks, rebates, sales incentives and allowances, certain royalties, distribution service fees, returns and losses are reasonably determinable, and when collectibility is reasonably assured. Revenue from the launch of a new or significantly unique product, for which we are unable to develop the requisite historical data on which to base estimates of returns, due to the uniqueness of the therapeutic area or delivery technology as compared to other products in our portfolio and in the industry, may be deferred until such time that an estimate can be determined and all of the conditions above are met and when the product has achieved market acceptance, which is typically based on dispensed prescription data and other information obtained during the period following launch.

Decisions made by wholesaler customers and large retail chain customers regarding the levels of inventory they hold (and thus the amount of product they purchase from us) can materially affect the level of our sales in any particular period and thus may not correlate to the number of prescriptions written for our products based on external third-party data. We believe that speculative buying of product, particularly in anticipation of possible price increases, has been the historic practice of many pharmaceutical wholesalers. Over the past two years, our wholesaler customers, as well as others in the

 

25


Table of Contents

industry, began modifying their business models from arrangements where they derive profits from the management of various discounts and rebates, to arrangements where they charge a fee for their services. In connection with this new wholesaler business model we have entered into distribution service agreements (or DSAs) with three of our wholesaler customers. These agreements, which pertain to branded products only, obligate the wholesalers to provide us with specific services, including the provision of periodic retail demand information and current inventory levels for our branded products held at their warehouse locations; additionally, under these DSAs, the wholesalers have agreed to manage the variability of their purchases and inventory levels within specified limits based on product demand.

As of March 31, 2007, we received information from our two largest U.S. wholesaler customers about the levels of inventory they held for our branded products. Based on this information, which we have not independently verified, we believe that total branded inventory held at these wholesalers is within normal levels. In addition, we also evaluate market conditions for products primarily through the analysis of wholesaler and other third party sell-through and market research data, as well as internally-generated information. We believe sales recorded for the three months ended March 31, 2007 were generally representative of underlying demand for the products.

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, certain royalties, DSA fees, returns and losses. These provisions, as described in greater detail below, 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 materially impacted. During the three months ended March 31, 2007, adjustments for prior periods’ sales deduction accruals amounted to approximately $0.6 million related to the reversal of 2006 excess accruals.

Returns

Our provision for returns consists of our estimates of future product returns, pricing adjustments and delivery errors. Consistent with industry practice, we maintain a return policy that allows our customers to return product within a specified period of time both prior and subsequent to the product’s expiration date. Our return policy allows customers to receive credit for expired products within six months prior to expiration and within one year after expiration. The primary factors we consider in estimating our potential product returns include:

 

   

the shelf life or expiration date of each product;

 

   

historical levels of expired product returns;

 

   

external data with respect to inventory levels in the wholesale distribution channel;

 

   

external data with respect to prescription demand for our products; and

 

   

estimated returns liability to be processed by year of sale based on analysis of lot information related to actual historical returns.

In determining our estimates for returns, we are required to make certain assumptions regarding the timing of the introduction of new products and the potential of these products to capture market share. In addition, we make certain assumptions with respect to the extent and pattern of decline associated with generic competition. To make these assessments we utilize market data for similar products as analogs for our estimations. We use our best judgment to formulate these assumptions based on past experience and information available to us at the time. We continually reassess and make the appropriate changes to our estimates and assumptions as new information becomes available to us.

Our estimate for returns may be impacted by a number of factors, but the principal factor relates to the level of inventory in the distribution channel. When we are aware of an increase in the level of inventory of our products in the distribution channel, we consider the reasons for the increase to determine if the increase may be temporary or other-than-temporary. Increases in inventory levels assessed as temporary will not result in an adjustment to our provision for returns. Other-than-temporary increases in inventory levels, however, may be indication that future product returns could be higher than originally anticipated and, accordingly, we may need to adjust our estimate for returns. Some of the factors that may be an indication that an increase in inventory levels will be temporary include:

 

   

recently implemented or announced price increases for our products; and

 

   

new product launches or expanded indications for our existing products.

Conversely, factors that may be an indication that an increase in inventory levels will be other-than-temporary include:

 

   

declining sales trends based on prescription demand;

 

26


Table of Contents
   

recent regulatory approvals to extend the shelf life of our products, which could result in a period of higher returns related to older product with the shorter shelf life;

 

   

introduction of new product or generic competition;

 

   

increasing price competition from generic competitors; and

 

   

recent changes to the National Drug Codes (“NDCs”) of our products, which could result in a period of higher returns related to product with the old NDC, as our customers generally permit only one NDC per product for identification and tracking within their inventory systems.

Rebates

We establish contracts with wholesalers, chain stores and indirect customers that provide for rebates, sales incentives, DSA fees, 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. Our rebate programs can generally be categorized into the following four types:

 

   

direct rebates;

 

   

indirect rebates;

 

   

managed care rebates; and

 

   

Medicaid and Medicare Part D rebates.

Direct rebates are generally rebates paid to direct purchasing customers based on a percentage applied to a direct customer’s purchases from us, including DSA fees paid to wholesalers under our DSA agreements, as described above. Indirect rebates are rebates paid to “indirect customers” which have purchased our products from a wholesaler under a contract with us.

We are subject to rebates on sales made under governmental and managed-care pricing programs. In estimating our provisions for these types of rebates, we consider relevant statutes with respect to governmental pricing programs and contractual sales terms with managed-care providers and group purchasing organizations. We estimate an accrual for managed-care, Medicaid and Medicare Part D rebates as a reduction of revenue at the time product sales are recorded. These rebate reserves are estimated based upon the historical utilization levels, historical payment experience, historical relationship to revenues and estimated future trends. Changes in the level of utilization of our products through private or public benefit plans and group purchasing organizations will affect the amount of rebates that we owe.

We participate in state government-managed Medicaid programs, as well as certain other qualifying federal and state government programs whereby discounts and rebates are provided to participating government entities. Medicaid rebates are amounts owed based upon contractual agreements or legal requirements with public sector (Medicaid) benefit providers, after the final dispensing of the product by a pharmacy to a benefit plan participant. Medicaid reserves are based on expected payments, which are driven by patient usage, contract performance, as well as field inventory that will be subject to a Medicaid rebate. Medicaid rebates are typically billed up to 180 days after the product is shipped, but can be as much as 270 days after the quarter in which the product is dispensed to the Medicaid participant. As a result, our Medicaid rebate provision includes an estimate of outstanding claims for end-customer sales that occurred but for which the related claim has not been billed, and an estimate for future claims that will be made when inventory in the distribution channel is sold through to plan participants. Our calculation also requires other estimates, such as estimates of sales mix, to determine which sales are subject to rebates and the amount of such rebates. Periodically, we adjust the Medicaid rebate provision based on actual claims paid. Due to the delay in billing, adjustments to actual may incorporate revisions of this provision for several periods. Medicaid pricing programs involve particularly difficult interpretations of statutes and regulatory guidance, which are complex and thus our estimates could differ from actual experience.

We continually update these factors based on new contractual or statutory requirements, and significant changes in sales trends that may impact the percentage of our products subject to rebates.

Chargebacks

The provision for chargebacks is one of the most significant and the most complex estimate used in the recognition of our revenue. We market and sell products directly to wholesalers, distributors, warehousing pharmacy chains, and other direct purchasing groups. We also market products indirectly to independent pharmacies, non-warehousing chains, managed care organizations, and group purchasing organizations, collectively referred to as “indirect customers.” We enter into

 

27


Table of Contents

agreements with some indirect customers to establish contract pricing for certain products. These indirect customers then independently select a wholesaler from which to purchase the products at these contracted prices. Alternatively, we may pre-authorize wholesalers to offer specified contract pricing to other indirect customers. Under either arrangement, we provide credit to the wholesaler for any difference between the contracted price with the indirect customer and the wholesaler’s invoice price. Such credit is called a chargeback. The primary factors we consider in developing and evaluating our provision for chargebacks include:

 

   

the average historical chargeback credits;

 

   

estimated future sales trends; and

 

   

an estimate of the inventory held by our wholesalers, based on internal analysis of a wholesaler’s historical purchases and contract sales.

Other sales deductions

We offer our customers 2% prompt pay cash discounts. Provisions for prompt pay discounts are estimated and recorded at the time of sale. We estimate provisions for cash discounts based on contractual sales terms with customers, an analysis of unpaid invoices and historical payment experience. Estimated cash discounts have historically been predictable and less subjective, due to the limited number of assumptions involved, the consistency of historical experience and the fact that we generally settle these amounts within thirty to sixty days.

Shelf-stock adjustments are credits issued to our customers to reflect decreases in the selling prices of our products. These credits are customary in the industry and are intended to reduce a customer’s inventory cost to better reflect current market prices. The determination to grant a shelf-stock credit to a customer following a price decrease is at our discretion rather than contractually required. The primary factors we consider when deciding whether to record a reserve for a shelf-stock adjustment include:

 

   

the estimated number of competing products being launched as well as the expected launch date, which we determine based on market intelligence;

 

   

the estimated decline in the market price of our product, which we determine based on historical experience and input from customers; and,

 

   

the estimated levels of inventory held by our customers at the time of the anticipated decrease in market price, which we determine based upon historical experience and customer input.

Royalties

Royalties represent amounts accrued pursuant to the license agreement with Hind Healthcare Inc. (Hind). Royalties, payable to Hind, 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®.

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.

Goodwill and Other Intangibles

Goodwill and other intangibles represent a significant portion of our assets and stockholders’ equity. As of March 31, 2007, goodwill and other intangibles comprised approximately 18% of our total assets and 23% of our stockholders’ equity. SFAS No. 142, Goodwill and Other Intangible Assets, 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

 

28


Table of Contents

our business and have similar economic characteristics. 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, 2007 and 2006, 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 ten to twenty years, with a weighted average useful life of approximately 16 years. 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. 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, generally 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.

Our goodwill and other intangible assets consist of the following at March 31, 2007 and December 31, 2006, respectively (in thousands):

Income Taxes

Provisions for income taxes are calculated on reported pre-tax income based on current tax laws, statutory tax rates and available tax incentives and planning opportunities in various jurisdictions in which we operate. Such provisions differ from the amounts currently receivable or payable because certain items of income and expense are recognized in different time periods for financial reporting purposes than for income tax purposes. Significant judgment is required in determining income tax provisions and evaluating tax positions. On January 1, 2007, the Company adopted the provisions of FASB

 

29


Table of Contents

Interpretation No. 48, Accounting for Uncertainty in Income Taxes, an Interpretation of FASB Statement No. 109 (“FIN 48”). FIN 48 creates a single model to address uncertainty in tax positions and clarifies the accounting for income taxes by prescribing the minimum recognition threshold a tax position is required to meet before being recognized in the financial statements. The provisions of FIN 48 apply to all material tax positions in all taxing jurisdictions for all open tax years. FIN 48 establishes a two-step process for evaluating tax positions. Step 1 – Recognition, requires the Company to determine whether a tax position, based solely on its technical merits, has a likelihood of more than 50 percent (“more-likely-than-not”) that the tax position taken will be sustained upon examination. Step 2 – Measurement, which is only addressed if Step 1 has been satisfied, requires the Company to measure the tax benefit as the largest amount of benefit, determined on a cumulative probability basis that is more- likely-than-not to be realized upon ultimate settlement. Whether the more-likely-than-not recognition threshold is met for a tax position, is a matter of judgment based on the individual facts and circumstances of that position evaluated in light of all available evidence.

Contingencies

The Company is subject to various patent, product liability, government investigations and other legal proceedings in the ordinary course of business. Legal fees and other expenses related to litigation are expensed as incurred and included in selling, general and administrative expenses. Contingent accruals are recorded when the Company determines that a loss related to a litigation matter is both probable and reasonably estimable. Due to the fact that legal proceedings and other contingencies are inherently unpredictable, our assessments involve significant judgments regarding future events.

Stock-Based Compensation

Prior to January 1, 2006, the Company accounted for its stock-based compensation plans under the recognition and measurement provisions of APB Opinion No. 25, Accounting for Stock Issued to Employees, and related Interpretations (“APB 25”), as permitted by FASB Statement No. 123, Accounting for Stock-Based Compensation. No stock-based employee compensation cost was recognized in the Statement of Operations for the years ended December 31, 2005 and 2004. Effective January 1, 2006, the Company adopted the fair value recognition provisions of FASB Statement No. 123(R), Share-Based Payment, using the modified-prospective-transition method. Under that transition method, compensation cost recognized during the three months ended March 31, 2007 includes: (a) compensation cost for all share-based payments granted prior to, but not yet vested as of January 1, 2006, based on the grant date fair value estimated in accordance with the original provisions of Statement No. 123, and (b) compensation cost for all share-based payments granted subsequent to January 1, 2006, based on the grant-date fair value estimated in accordance with the provisions of Statement No. 123(R). Results for prior periods have not been restated.

For all of the Company’s stock-based compensation plans, the fair value of each option grant was estimated at the date of grant using the Black-Scholes option-pricing model. Black-Scholes utilizes assumptions related to volatility, the risk-free interest rate, the dividend yield (which is assumed to be zero, as the Company has not paid cash dividends to date and does not currently expect to pay cash dividends) and the expected term of the option. Expected volatilities utilized in the model are based mainly on the historical volatility of the Company’s stock price and other factors. The risk-free interest rate is derived from the U.S. Treasury yield curve in effect at the time of grant. We estimate the expected term of options granted based on our historical experience with our employees’ exercise of stock options and other factors. Changes in the inputs and assumptions can materially affect the measure of the estimated fair value of our employee stock options. Also, the accounting estimate of stock-based compensation expense is reasonably likely to change from period to period as further stock options are granted and adjustments are made for stock option forfeitures and cancellations. Option-pricing models were developed for use in estimating the value of traded options that have no vesting or hedging restrictions and are fully transferable. Because the Company’s employee stock options have certain characteristics that are significantly different from traded options, and because changes in the subjective assumptions can materially affect the estimated value, in management’s opinion, the existing valuation models may not provide an accurate measure of the fair value of the Company’s employee stock options. Although the fair value of employee stock options has been determined in accordance with SFAS 123(R), using an option-pricing model, that value may not be indicative of the fair value observed in a willing buyer/willing seller market transaction. The total value of compensation expense for restricted stock is equal to the closing price of Endo shares on the date of grant.

As of March 31, 2007, the total remaining unrecognized compensation cost related to non-vested stock options and restricted stock amounted to $41.9 million. The weighted average remaining requisite service period of the non-vested stock options and restricted stock was 2.8 years and 1.9 years, respectively. This unrecognized compensation cost does not include the impact of any future stock-based compensation awards.

Results of Operations

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 compensation paid by Endo Pharma LLC, impairment of intangible assets, purchased in-process research and development charges and certain upfront, milestone and certain other payments made or accrued pursuant to acquisition or licensing agreements.

Three Months Ended March 31, 2007 Compared to the Three Months Ended March 31, 2006

Net Sales. Net sales for the three months ended March 31, 2007 increased to $254.4 million from $205.0 million in the comparable 2006 period. This increase in net sales was primarily due to increased sales of Lidoderm®, as well as sales of Opana® and Opana® ER , which were launched in the second half of 2006. Net sales of Opana® and Opana® ER for the three months ended March 31, 2007, includes $13.8 million of deferred revenue for commercial shipments made to customers during 2006. These increases were partially offset by the reduction in sales of our generic oxycodone extended-release tablets, resulting from the Company’s settlement with Purdue (as described in more detail below). Net sales of Lidoderm® increased by 23% to $154.1 million from $125.1 million in the comparable 2006 period due to the continued prescription growth of the product. We believe the continued growth of Lidoderm® is driven by the product’s proven clinical effectiveness combined with incremental promotional support generated by the expansion of our sales force in 2006. In addition, we have benefited from a shift in enrollees, based on estimated patient enrollment, from Medicaid to Medicare under Medicare Part D, which resulted in a net decrease in the relevant rebate accruals. Sales of our generic oxycodone extended-release tablets ceased on December 31, 2006 causing a $9.0 million decrease in sales for the three months ended March 31, 2007 versus the comparable 2006 period. In August 2006, we announced that we had reached an agreement with Purdue to settle long-running litigation claiming that our oxycodone extended-release tablets, 10mg, 20mg, 40mg, and 80mg, a bioequivalent versions of Purdue’s OxyContin®, infringe Purdue’s patents. Pursuant to the settlement, we discontinued selling our oxycodone extended-release products effective December 31, 2006. Net sales of our other generic products decreased to $25.8 million from $31.7 million in the comparable 2006 period. Continued generic competition has decreased both our market share as well as the price of these other generic products. Generic competition with our products may have a material impact on our results of operations and cash flows in the future. Due primarily to the expected increases in the net sales of Lidoderm® and Opana® ER and Opana® partially offset by the discontinuation of sales of our generic oxycodone extended-release tablets, we expect net sales in 2007 to be approximately $1.025 billion and $1.050 billion. There can be no assurance of Endo achieving these results.

Gross Profit. Gross profit for the three months ended March 31, 2007 increased by 32% to $206.0 million from $156.3 million in the comparable 2006 period. Gross profit margins increased to 81% from 76% in the comparable 2006 period. This increase is primarily attributable to a favorable mix of product revenues, as we derived a higher proportion of total revenue from higher margin branded products compared to revenues in the comparable 2006 period. We expect to continue to benefit from this favorable product mix for the remainder of 2007, as higher-margin branded products will continue to represent a higher proportion of total revenue when compared to 2006. However, this favorability will be partially offset by a decrease in our average selling price as we pursue contracting activities, particularly with managed care organizations, throughout the remainder of 2007. As such, we expect full year gross margins to be above 2006, but below gross margins achieved during the three months ended March 31, 2007.

Selling, General and Administrative Expenses. Selling, general and administrative expenses for the three months ended March 31, 2007 decreased to $92.8 million from $100.2 million in the comparable 2006 period. This decrease was primarily due to the accrual of compensation expense and the related employer payroll taxes of approximately $41.3 million, during the three months ended March 31, 2006. These amounts, are related to the one-time bonuses Endo Pharma LLC paid or to be paid to certain of our executives (see “Note 9. RELATED PARTY TRANSACTIONS – Executive Compensation”). The impact of these prior year amounts was partially offset by an increase in sales and promotional efforts in 2007 over the comparable 2006 period due to our continued investment in our commercial business and our infrastructure to support our products and pipeline, including the addition of approximately 220 sales representatives, the pre-launch expenses for Frova® (MM) and the continued launch expenses of Opana® ER and Opana®. During 2007, selling, general and administrative expenses is expected to rise, excluding the Endo Pharma LLC items noted above, due to increased promotional support behind Endo’s key on-market products, including the full-year impact of the expansion of the sales force that occurred in the second half of 2006, combined with continuing investments in infrastructure to support Endo’s long-term growth.

Research and Development Expenses. Research and development expenses for the three months ended March 31, 2007 increased to $26.4 million from $25.2 million in the comparable 2006 period. This increase is primarily attributable to the ongoing clinical development of RapinylTM, our topical ketoprofen patch, our transdermal sufentanil patch and EN3285, our oral rinse for the treatment of oral mucositis obtained through our acquisition of RxKinetix in October 2006. This increase in spending was partially offset by the year-over-year difference in up-front license fees and milestone payments expensed during 2007 compared to 2006. During the three months ended March 31, 2007, we expensed $5.6 million in milestone payments related primarily to Rapinyl™. In comparison, during the three months ended March 31, 2006, we expensed milestone payments of $10.2 million primarily related to RapinylTM and the topical ketoprofen patch. In 2007, we expect to direct the majority of our incremental research and development spending on the ongoing clinical trials for RapinylTM, the topical ketoprofen patch, the transdermal sufentanil patch and EN 3285. Additionally, we expect to increase our investment in post-marketing clinical studies in support of our on-market products.

Depreciation and Amortization. Depreciation and amortization for the three months ended March 31, 2007 decreased to $3.9 from $4.0 million in the comparable 2006 period primarily due to the impairment charges recorded related to the SkyePharma and Zars intangible assets in the fourth quarter of 2006. We expect depreciation and amortization will increase from current levels as we increase our capital expenditures and as we continue to license in products and technologies.

Interest Income, Net. Interest income, net for the three months ended March 31, 2007 increased to $7.0 million from $4.6 million in the comparable 2006 period. This change is substantially due to the increased interest income earned as a result of higher cash balances and higher returns earned during the first quarter of 2007 compared to the first quarter of 2006.

Income Tax. Income tax for the three months ended March 31, 2007 increased to $32.8 million from $11.0 million in the comparable 2006 period. This increase is due to the increase in income before income tax for the three months ended March 31, 2007. In addition, our effective income tax rate increased to 36.5% for three months ended March 31, 2007 from 35.0% in the comparable 2006 period. This increase in the effective income tax rate is primarily related to research and development tax credits realized during the three months ended March 31, 2006.

Liquidity and Capital Resources

Our principal source of liquidity is cash generated from operations. Our principal liquidity requirements are for working capital for operations, acquisitions, licenses, milestone payments and capital expenditures.

During the three months ended March 31, 2007, we increased cash and cash equivalents by $102.8 million to a balance of $730.9 million. These funds, in addition to our cash generated from future operations are expected to be sufficient to meet our normal operating, investing and financing requirements in the foreseeable future, including the funding of our pipeline research and development projects in the event that our collaboration partners are unable or unwilling to fund their portion of any particular project. We may use a portion of our cash and cash equivalents for possible acquisitions and licensing opportunities.

Net Cash Provided by Operating Activities. Net cash provided by operating activities decreased to $128.5 million for the three months ended March 31, 2007 from $165.3 million for the three months ended March 31, 2006. Significant components of our operating cash flows for the three months ended March 31, 2007 and 2006 are as follows:

Net cash provided by operating activities decreased by $36.8 million to $128.5 million for the three months ended March 31, 2007. This decrease is primarily a result of a $42.0 million decrease in the operating cash flow impact of the changes in operating assets and liabilities, partially offset by changes in other items reconciling net income to cash provided by operating activities, the largest of which is a $41.3 million decrease in the operating cash flow impact related to selling, general and administrative expenses to be funded by Endo Pharma LLC. The decrease in the operating cash flow impact of changes in operating assets and liabilities is primarily due to a $54.5 million decrease in the cash flow impact related to income taxes, due to the receipt of an income tax refund in 2006 as a result of the significant tax deductions generated in 2005 from the exercises of 22.2 million Endo Pharma LLC stock options. This was partially offset by a $7.8 million increase in the cash flow impact of accounts receivable as a result of the timing and volume of our sales during the first quarter of 2007 when compared to the first quarter of 2006 and other operating cash flow increases related to other operating assets and liabilities primarily due to the timing of payments and expenditures during the three months ended 2007 when compared to the same period in 2006. During the three months ended March 31 2006, due to Endo Pharma LLC’s intention to payout one-time bonuses, the Company recorded in selling, general and administrative expense, executive compensation of $41.3 million for one-time cash bonuses paid to each of Ms. Carol Ammon, our Chairman of the Board and former Chief Executive Officer, Mr. Peter Lankau, our President and Chief Executive Officer, Ms. Caroline Manogue, our Executive Vice President, Chief Legal Officer and Secretary, and Mr. Jeffrey Black, our former Executive Vice President, Chief Financial Officer and Treasurer. These bonus payments were made by the Company in April 2006 and repaid to us by Endo Pharma LLC in the third quarter of 2006 with interest. No such payments were made or accrued during the three months ended March 31, 2007.

Net Cash Used in Investing Activities. Net cash used in investing activities decreased to $7.0 million for the three months ended March 31, 2007 from $14.9 million for the three months ended March 31, 2006. During the three months ended March 31, 2007, the Company paid $4.3 million for capital expenditures and invested an additional $2.8 million in Life Sciences Opportunities Fund (Institutional) II, L.P., bringing our total cash investment to $5.5 million as of March 31, 2007. During the three months ended March 31, 2006, the Company paid $3.9 million for capital expenditures and $11.0 million for the purchase of a license right.

Net Cash Used in Financing Activities. Net cash used in financing activities decreased to $18.7 million for the three months ended March 31, 2007 from $67.4 million for the three months ended March 31, 2006. The decrease is primarily due to a $20.0 million payment to Endo Pharma LLC pursuant to the tax sharing agreement compared to a $96.7 million payment in 2006 partially offset by a $27.8 million decrease in the cash flow impact related to the tax benefits of stock options exercised.

Working Capital. Working capital increased to $754.5 million as of March 31, 2007 from $697.9 million as of December 31, 2006. The components of our working capital as of March 31, 2007 and December 31, 2006 are below:

 

     March 31,

   December 31,
2006

Working capital

   $ 754,465    $ 697,915
             

The primary drivers for the increase in working capital were the increase in cash and cash equivalents as well as a reduction in the amounts due to Endo Pharma LLC as a result of payments to Endo Pharma LLC during 2006 which reduced the balance due to Endo Pharma LLC to $18.7 million at March 31, 2007 from $38.7 million at December 31, 2006. Accounts receivable at March 31, 2007 decreased to $201.4 million from $279.2 million at December 31, 2006. Day sales in accounts receivable decreased to 44 days as of March 31, 2007 from 55 days as of December 31, 2006. The decrease is

primarily attributable to a higher proportion of sales from branded products than generic products during the three months ended March 31, 2007, which resulted in a higher collection rate as payment on branded products generally, is received more quickly than from generic products. At March 31, 2007, we reclassified to a current liability, $15 million of the “estimated amount due seller” which at December 31, 2006 was classified, in its entirety, as a non-current liability. The current portion of the “estimated amount due seller” is payable upon the achievement of certain clinical and regulatory milestones under the terms of the RxKinetix acquisition. This increase in current liabilities was offset by a decrease in income taxes payable from $12.2 million at December 31, 2007 to $3.6 million at March 31, 2007 as a result of income tax payments made during the three months ended March 31, 2007, as well as the recognition during the quarter, of $13.8 million of Opana® and Opana® ER deferred revenue from 2006, which reduced our accrued liabilities balance.

Acquisition. On October 12, 2006, the Company acquired all of the outstanding common stock of privately held RxKinetix, Inc. RxKinetix specializes in developing new therapeutics focused on improving the quality of life for patients being treated for cancer. RxKinetix’s most advanced product, now named EN 3285, is currently in clinical Phase II for the prevention of oral mucositis, a painful, debilitating and often dose-limiting side effect that afflicts many patients being treated for cancer with radiation and/or chemotherapy. RxKinetix is a development stage company and therefore was accounted for as an asset acquisition. The results of operations for RxKinetix have been included in our consolidated financial statements beginning on the acquisition date.

The purchase price of RxKinetix, as of the acquisition date, was $20.5 million which was funded from our existing cash on hand. Additional contingent cash purchase consideration of up to $95 million may become due upon the achievement of certain clinical and regulatory milestones. The Company has allocated the purchase price to the RxKinetix assets acquired and liabilities assumed at their estimated fair values, based on a number of factors, including the use of an independent appraisal. Estimated fair values were determined through the use of a discounted cash flow analysis using market participant assumptions. Of the purchase price, approximately $26.0 million has been allocated to tangible and intangible assets to be used in research and development activities and those assets have been written-off to purchased in-process research and development, as of the acquisition date. The excess of fair value of the net assets acquired compared to the amount paid as of the acquisition date has been reflected as “estimated amount due seller” in accordance with SFAS No. 141, Business Combinations. Any contingent consideration paid in the future will be first applied to reduce the amount recorded as estimated amount due seller, and thereafter to the net assets acquired based on their relative fair values. Our preliminary purchase allocation is subject to revision; subsequent revisions, if any, are not expected to be material. At March 31, 2007, we reclassified to a current liability, $15 million of the “estimated amount due seller” which at December 31, 2006 was classified, in its entirety, as a non-current liability. The current portion of the “estimated amount due seller” is payable upon the achievement of certain clinical and regulatory milestones under the terms of the RxKinetix acquisition. There has not been any material change in the estimated fair values assigned to the assets acquired and liabilities assumed since the date of acquisition.

The following table summarizes the estimated fair values of the assets acquired and liabilities assumed as of the date of acquisition (in thousands):

As a result of our acquisition of RxKinetix, Inc., we acquired one significant in-process research and development project, known as EN 3285, a topical oral rinse with the active ingredient formulated in its proprietary ProGelz® drug delivery platform. All of the purchased in-process research and development value from this transaction was assigned to EN

3285 since the other products, as of the acquisition date, were very early stage and did not meet the criteria to be recognized as assets. As of the acquisition date, EN 3285 was in clinical Phase II for the prevention of oral mucositis, painful mouth sores that often occur in cancer patients undergoing radiation and chemotherapeutic treatment. During the course of high-dose cancer therapy and bone marrow transplantation, patients often develop painful and debilitating oral inflammation, or mucositis, in the mouth. The resulting weight loss, dehydration and, in some cases, infection often lead to dose-limitation of chemotherapy and radiation therapy, and contribute considerably to cancer and transplant-related morbidity and mortality. Further, these side effects add to related medical costs by prolonging hospital stays, increasing antibiotic, fluid, and analgesic use, and requiring patients to receive parenteral nutritional support. Of the estimated 800,000 patients treated for cancer in the United States, as many as 400,000 may develop the debilitating complications of oral mucositis as a result of their treatment. RxKinetix also had other products in early- stage development based on the ProGelz® technology. We plan to conduct additional Phase II trials of EN 3285 to continue to characterize the clinical profile of the product in the intended patient population — head and neck cancer patients undergoing combination treatment of radiation and chemotherapy.

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 provided us with a line of credit of $75.0 million. We did not borrow any amounts under the facility during 2006, and the line of credit expired on December 21, 2006. The Company has not renegotiated a credit facility at this time.

Tax Sharing Agreement. On July 14, 2000, Endo Pharma LLC was formed in connection with our merger with Algos Pharmaceutical Corporation (Algos) 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 held approximately 15% of our common stock at December 31, 2005, but less than 1% of our common stock as of March 31, 2007, in which affiliates of Kelso & Company and certain current and former 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 have been and will be delivered. Because Endo Pharma LLC, and not us, has been and 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 March 31, 2007, approximately 36 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 March 31, 2007, approximately $773 million), which is estimated to result in a tax benefit amount of approximately $298 million. Under the tax sharing agreement, we are required to pay this $298 million, $272 million of which has already been paid as of March 31, 2007, 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. Additionally, as part of the tax sharing agreement, Endo Pharma LLC will reimburse us for the after-tax employer payroll taxes paid by us as a result of the exercise of the 36 million options discussed above. We have paid approximately $11 million in employer payroll taxes, of which Endo Pharma LLC will reimburse us for approximately $7 million, which represents the after-tax employer payroll tax paid by us for the periods from 2001 through March 31, 2007. As of March 31, 2007, our net liability due to Endo Pharma LLC is approximately $18.7 million. 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.

During the three months ended March 31, 2007, approximately 19,000 shares underlying stock options granted under the Endo Pharma LLC stock option plans were exercised. Since we expect the attributable compensation charge deductions to be usable to reduce our taxes in 2007, we are obligated, under our amended tax sharing agreement, to pay to Endo Pharma LLC an additional tax benefit amount of approximately $0.2 million, which is included in our net liability due to Endo Pharma LLC referred to above. Fifty percent of the estimated tax benefit amount attributable to these exercises and any additional tax benefits attributable to the exercise of stock options granted under the Endo Pharma LLC stock option plans in 2007 will be due within 15 business days of the date we receive an opinion on our final audited 2007 financial statements from our independent registered public accounting firm, and the remaining tax benefit amount attributable to 2007 is due within 30 business days of the date on which we file our 2007 tax return with the Internal Revenue Service.

As of March 31, 2007, there were 55,968 stock options, which expire in August 2007, remaining to be exercised under the Endo Pharma LLC stock option plans. Using a weighted average exercise price of $2.42 per share and an assumed tax rate of 38.25%, if all of these remaining stock options under the Endo Pharma LLC stock option plans were vested and exercised, and assuming the price of our common stock was $29.40 per share, the closing price on March 30, 2007, we would generally be able to deduct, for income tax purposes, compensation of approximately $1.5 million, which could result in a tax benefit amount of approximately $0.6 million payable to Endo Pharma LLC in 2008. This would represent the final tax sharing payment due to Endo Pharma LLC.

As of March 31, 2007, there were no options remaining to be granted under the Endo Pharma LLC stock option plans.

Executive Compensation. In March 2006, Endo Pharma LLC advised our Board of Directors that it intended to pay a one-time cash bonus to each of Mr. Peter Lankau, our President and Chief Executive Officer, Ms. Caroline Manogue, our Executive Vice President, Chief Legal Officer and Secretary, and Mr. Jeffrey Black, our former Executive Vice President, Chief Financial Officer and Treasurer in the amount of $3 million, $6 million and $10 million, respectively, in recognition of their significant contributions to our success. These bonus payments have been recorded in selling, general and administrative expenses during the year ended December 31, 2006. These payments were made by the Company in April 2006 and repaid to us by Endo Pharma LLC in the third quarter of 2006 with interest. In addition, only a portion of these bonus payments will be deductible for federal and state income tax purposes. We are not required to pay nor will we pay to Endo Pharma LLC the amount of any of the tax benefits related to these bonus payments pursuant to the tax sharing agreement between us and Endo Pharma LLC. These bonuses will be funded entirely by Endo Pharma LLC, with no contribution by us and they have been treated as a capital contribution by Endo Pharma LLC.

Endo Pharma LLC also informed us that, in connection with its eventual winding-up, it would make a special allocation to Ms. Carol Ammon, our Chairman of the Board and former Chief Executive Officer, of approximately $22 million, with all or a portion of Ms. Ammon’s payment being satisfied by granting to her the remaining unallocated Endo Pharma LLC stock options of approximately 0.8 million shares under the Endo Pharma LLC stock option plans. This amount has been recorded in selling, general and administrative expenses during the year ended December 31, 2006 and as a capital contribution by Endo Pharma LLC. This grant of options to Ms. Ammon was made during the fourth quarter of 2006. The 0.8 million options were granted by Endo Pharma LLC to Ms. Ammon in the fourth quarter of 2006, as described above, at an exercise price of $2.42 per share. Therefore, approximately $20 million of the approximately $22 million recorded in the first quarter of 2006 was reclassified as a stock compensation expense representing the fair value of the option on the date of grant. These options were immediately vested and exercised by Ms. Ammon and the resulting compensation charge deduction of approximately $19 million and the resulting tax sharing obligation to Endo Pharma LLC is included in our tax sharing liability discussed above. Endo Pharma LLC intends to pay the remaining $2 million to Ms. Ammon in 2007.

Related Party Matters. Robert Ammon, the brother of our current Chairman and former Chief Executive Officer, is employed by the Company as a senior national account executive and has been since the company’s founding as a private company in 1997. It is expected that his 2007 total compensation, including base salary, incentive compensation, long-term incentive compensation and all benefits (including health benefits), will be in excess of $120,000 but will not exceed $250,000. Marisa Lankau, the daughter of our President and Chief Executive Officer, is employed by the Company as a sales representative and has been since 2006. It is expected that her 2007 total compensation, including base salary, incentive compensation, long-term incentive compensation and all benefits (including health benefits), may be in excess of $120,000 but will not exceed $125,000.

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 three months ended March 31, 2007 follows:

DURECT Corporation

In April 2007, DURECT and Endo entered into Amendment No. 4 to the Development, Commercialization and Supply License Agreement dated November 8, 2002 (the “DURECT CHRONOGESICTM License Agreement”) relating to the development and commercialization of the CHRONOGESICTM product candidate in the U.S. and Canada. Prior to the present amendment, in addition to other specified termination rights provided to both parties, the DURECT CHRONOGESICTM License Agreement provided Endo with a right to terminate the DURECT CHRONOGESICTM License Agreement starting March 31, 2007 in the event that DURECT had not commenced a specified clinical trial for the CHRONOGESICTM product candidate on or before March 31, 2007, provided that Endo provided DURECT written notice of such termination prior to April 30, 2007. Under Amendment No. 4, the foregoing termination right was amended to provide Endo with the right to terminate the DURECT CHRONOGESICTM License Agreement in the event that (i) DURECT had not delivered to Endo on or before March 31, 2008 a written notice that a human pharmacokinetic trial had been completed with the CHRONOGESICTM product candidate, together with a full study report of the results of the trial or (ii) Endo, determines, in its sole discretion, to terminate the DURECT CHRONOGESICTM License Agreement during the sixty-day period after DURECT’s delivery of such notice, provided that, in each case Endo delivers to DURECT its written notice of termination prior to April 30, 2008. Under Amendment No. 4, Endo shall not be responsible for any development costs for the CHRONOGESICTM product candidate prior to May 1, 2008. Commencing on May 1, 2008, unless the DURECT

CHRONOGESICTM License Agreement is earlier terminated by Endo, Endo will fund 50% of the ongoing development costs for the CHRONOGESICTM product candidate in accordance with the terms of the DURECT CHRONOGESICTM License Agreement. A copy of Amendment No. 4 to the Development, Commercialization and Supply License Agreement between DURECT Corporation and Endo is filed hereto as Exhibit 10.42.5 in Part II, Item 6 of this Report. 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 DURECT CHRONOGESIC™ 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™ License Agreement also contains terms and conditions customary for this type of arrangement, including representations, warranties, indemnities and termination rights. The DURECT CHRONOGESIC™ License Agreement generally lasts until the underlying patents on the product expire. With respect to termination rights, the DURECT CHRONOGESIC™ License Agreement permits Endo to terminate its continued participation under a number of circumstances, one of which could require Endo to pay DURECT up to $10.0 million.

SkyePharma, Inc.

In January 2007, following an assessment of the status of DepoDur®, we announced that we notified SkyePharma PLC of our intent to terminate our development and commercialization agreement for this product and, in February 2007, entered into a termination agreement with SkyePharma whereby the Development and Marketing Strategic Alliance Agreement terminated in its entirety on March 31, 2007. In order to provide for the continued commercial support of the DepoDur® product and the transition of such product to SkyePharma on March 31, 2007, Endo continued to provide a number of services and undertake certain activities. Specifically, Endo employed commercially reasonable efforts to maintain and continue all U.S. commercial activities in support of DepoDur® through March 31, 2007, and support and/or undertake the transition of certain Endo functions and activities (including third party activities) to SkyePharma that were useful and necessary for SkyePharma to assume commercial and related responsibilities for DepoDur® in the U.S.

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, $17.7 million of which has been recorded through March 31, 2007 and included in research and development expense. Of this $17.7 million expensed through March 31, 2007, $5.2 million has been recorded during each of the three months ended March 31, 2007 and 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 compensation paid by Endo Pharma LLC, impairment of intangible assets, 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.

(1)

On April 24, 2007, our wholly owned subsidiary Endo Pharmaceuticals Inc. (“Endo”) and Teikoku Seiyaku Co., Ltd. / Teikoku Pharma USA, Inc. (collectively, “Teikoku”) amended their Supply and Manufacturing Agreement dated as of November 23, 1998 by and between Endo and Teikoku, pursuant to which Teikoku manufactures and supplies Lidoderm® (lidocaine patch 5%) (the “Product”) to Endo. This amendment is referred to as the Amended Agreement. Under the terms of the Amended Agreement, Endo has agreed to purchase a certain number of patches per year for each year in the remaining term of the Amended Agreement. Teikoku has agreed to fix the price of the Product for a specified period of time after which the price will be adjusted at future dates certain based on a price index defined in the Amendment Agreement. Since future price changes are unknown, for purposes of this contractual obligations table, all amounts scheduled above represent the minimum patch quantities at the price currently existing under the Amended Agreement. We will update the Teikoku purchase commitments upon future price changes made in accordance with the Amended Agreement.

(2) 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 of December 31, 2006, we have invested $2.7 million in this partnership.

In addition, we have agreed to certain contingent payments in certain of our acquisition, license, collaboration and other agreements. Payments under these agreements generally become due and payable only upon the achievement of certain developmental, regulatory, commercial and/or other milestones. Due to the fact that it is uncertain if and when these milestones will be achieved, such contingencies have not been recorded in our consolidated balance sheet, except for the $15.5 million estimated amount due seller related to our acquisition of RxKinetix, and are not reflected in the table above. In addition, under certain arrangements, we may have to make royalty payments based on a percentage of future sales of the products in the event regulatory approval for marketing is obtained. From a business perspective, we view these payments favorably as they signify that the products are moving successfully through the development phase toward commercialization.

As more fully described in Footnote 12 to the Condensed Consolidated Financial Statements, on January 1, 2007, we adopted FIN 48 and have recorded a $6.4 million non-current liability representing the Company’s unrecognized tax benefits with respect to our uncertain tax positions. Due to the nature and timing of the ultimate outcome of these uncertain tax positions, we can not make a reasonably reliable estimate of the amount and period of related future payments. Therefore, our FIN 48 liability has been excluded from the above contractual obligations table.

Recent Accounting Pronouncements

In July 2006, the FASB issued FASB Interpretation No. 48 (“FIN 48”), Accounting for Uncertainty in Income Taxes, an interpretation of FASB Statement No. 109, Accounting for Income Taxes. FIN 48 creates a single model to address uncertainty in tax positions. FIN 48 clarifies the accounting for income taxes by prescribing the minimum recognition threshold a tax position is required to meet before being recognized in the financial statements. FIN 48 also provides guidance on derecognition, measurement, classification, interest and penalties, accounting in interim periods, disclosure and transition. In addition, FIN 48 clearly scopes out income taxes from SFAS No. 5, Accounting for Contingencies. FIN 48 is effective for fiscal years beginning after December 15, 2006. We have adopted FIN No. 48 as of January 1, 2007. The adoption resulted in a charge of $2.7 million recorded directly to retained earnings as a cumulative-effect of a change in accounting principle. See Note 12 for further discussion.

In September 2006, the FASB issued SFAS No. 157, Fair Value Measurements, which addresses how companies should measure fair value when they are required to use a fair value measure for recognition or disclosure purposes under accounting principles generally accepted in the United States. SFAS No. 157 is effective for fiscal years beginning after November 15, 2007. The Company is currently evaluating the impact of the adoption of this Statement on its financial statements.

In February 2007, the FASB issued SFAS No. 159 (“SFAS 159”) The Fair Value Option for Financial Assets and Financial Liabilities, providing companies with an option to report selected financial assets and liabilities at fair value. This

Standard’s objective is to reduce both complexity in accounting for financial instruments and the volatility in earnings caused by measuring related assets and liabilities differently. Generally accepted accounting principles have required different measurement attributes for different assets and liabilities that can create artificial volatility in earnings. SFAS 159 helps to mitigate this type of accounting-induced volatility by enabling companies to report related assets and liabilities at fair value, which would likely reduce the need for companies to comply with detailed rules for hedge accounting. SFAS 159 also establishes presentation and disclosure requirements designed to facilitate comparisons between companies that choose different measurement attributes for similar types of assets and liabilities. This Standard requires companies to provide additional information that will help investors and other users of financial statements to more easily understand the effect of the Company’s choice to use fair value on its earnings. It also requires entities to display the fair value of those assets and liabilities for which the Company has chosen to use fair value on the face of the balance sheet. SFAS 159 is effective for fiscal years beginning after November 15, 2007. The Company is currently evaluating the impact of the adoption of this Statement on its financial statements

Table of Contents

the development and commercialization of the CHRONOGESICTM product candidate in the U.S. and Canada. Prior to the present amendment, in addition to other specified termination rights provided to both parties, the DURECT CHRONOGESICTM License Agreement provided Endo with a right to terminate the DURECT CHRONOGESICTM License Agreement starting March 31, 2007 in the event that DURECT had not commenced a specified clinical trial for the CHRONOGESICTM product candidate on or before March 31, 2007, provided that Endo provided DURECT written notice of such termination prior to April 30, 2007. Under Amendment No. 4, the foregoing termination right was amended to provide Endo with the right to terminate the DURECT CHRONOGESICTM License Agreement in the event that (i) DURECT had not delivered to Endo on or before March 31, 2008 a written notice that a human pharmacokinetic trial had been completed with the CHRONOGESICTM product candidate, together with a full study report of the results of the trial or (ii) Endo, determines, in its sole discretion, to terminate the DURECT CHRONOGESICTM License Agreement during the sixty-day period after DURECT’s delivery of such notice, provided that, in each case Endo delivers to DURECT its written notice of termination prior to April 30, 2008. Under Amendment No. 4, Endo shall not be responsible for any development costs for the CHRONOGESICTM product candidate prior to May 1, 2008. Commencing on May 1, 2008, unless the DURECT CHRONOGESICTM License Agreement is earlier terminated by Endo, Endo will fund 50% of the ongoing development costs for the CHRONOGESICTM product candidate in accordance with the terms of the DURECT CHRONOGESICTM License Agreement. A copy of Amendment No. 4 to the Development, Commercialization and Supply License Agreement between DURECT Corporation and Endo is filed hereto as Exhibit 10.42.5 in Part II, Item 6 of this Report.
