License And Collaboration Agreements	NOTE 8. LICENSE AND COLLABORATION AGREEMENTS *Commercial Products* Novartis AG and Novartis Consumer Health, Inc. On March 4, 2008, we entered into a License and Supply Agreement (the Voltaren^® Gel Agreement) with and among Novartis AG and Novartis Consumer Health, Inc (Novartis) to obtain the exclusive U.S. marketing rights for the prescription medicine Voltaren^® Gel (Voltaren^® Gel or Licensed Product). Voltaren^® Gel received regulatory approval in October 2007 from the U.S. Food and Drug Administration (the FDA), becoming the first topical prescription treatment for use in treating pain associated with osteoarthritis and the first new product approved in the U.S. for osteoarthritis since 2001. Voltaren^® Gel was granted marketing exclusivity in the U.S. as a prescription medicine until October 2010. Under the terms of the five-year Voltaren^® Gel Agreement, Endo made an upfront cash payment of $85 million. Endo has agreed to pay royalties to Novartis on annual Net Sales of the Licensed Product, subject to certain thresholds as defined in the Voltaren^® Gel Agreement. In addition, Endo has agreed to make certain guaranteed minimum annual royalty payments of $30 million per year payable in the fourth and fifth year of the Voltaren^® Gel Agreement, subject to certain limitations including the launch of a generic to the Licensed Product in the United States. These guaranteed minimum royalties will be creditable against royalty payments on an annual basis such that Endo's obligation with respect to each year is to pay the greater of (i) royalties payable based on annual net sales of the Licensed Product or (ii) the guaranteed minimum royalty for such Voltaren^® Gel Agreement year. No royalty payments were made to Novartis during the three or six months ended June 30, 2011 or 2010. Novartis is also eligible to receive a one-time milestone payment of $25 million if annual net sales of Voltaren^® Gel exceed $300 million in the U.S. The $85 million upfront payment and the present value of the guaranteed minimum royalties have been capitalized as an intangible asset in the amount of $129 million, representing the fair value of the exclusive license to market Voltaren^® Gel. We are amortizing this intangible asset into cost of revenues over its estimated five-year useful life. Endo is solely responsible to commercialize the Licensed Product during the term of the Voltaren^® Gel Agreement. With respect to each year during the term of the Voltaren^® Gel Agreement, Endo is required to incur a minimum amount of annual advertising and promotional expenses on the commercialization of the Licensed Product, subject to certain limitations. In addition, Endo is required to perform a minimum number of face-to-face one-on-one discussions with physicians and other healthcare practitioners (Details) for the purpose of promoting the Licensed Product within its approved indication during each year of the Voltaren^® Gel Agreement. Further, during the term of the Voltaren^® Gel Agreement, Endo will share in the costs of certain clinical studies and development activities initiated at the request of the FDA or as considered appropriate by Novartis and Endo. During the term of the Voltaren^® Gel Agreement, Endo has agreed to purchase all of its requirements for the Licensed Product from Novartis. The price was fixed for the first year and subject to annual changes based upon changes in the producer price index and raw materials. Novartis has the exclusive right, at its sole discretion, to effect a switch of the Licensed Product from a prescription product to an over-the-counter (OTC) product in the United States (an OTC Switch) by filing an amendment or supplement to the Licensed Product New Drug Application or taking any other action necessary or advisable in connection therewith to effect the OTC Switch, and thereafter to commercialize such OTC product. Notwithstanding the foregoing, Novartis shall not launch an OTC equivalent product prior to a time specified in the Voltaren^® Gel Agreement, and Novartis shall not take any action that results in the loss of the prescription product status for the Licensed Product prior to such time. Novartis will notify Endo if it submits a filing to the FDA in respect of an OTC equivalent product. In the event that Novartis gains approval of an OTC equivalent product that results in the Licensed Product being declassified as a prescription product, then Novartis will make certain royalty payments to Endo on net sales of such OTC equivalent product in the United States by Novartis, its affiliates and their respective licensees or sublicensees as set forth in the Voltaren^® Gel Agreement. As a condition to the payment of any and all such royalties, net sales of the Licensed Product in the United States must have exceeded a certain threshold prior to the launch of the OTC equivalent product by Novartis or its affiliates. The initial term of the Voltaren^® Gel Agreement will expire on June 30, 2013. Endo has the option to extend the Voltaren^® Gel Agreement for two successive one year terms. The Voltaren^® Gel Agreement will remain in place after the first two renewal terms unless either party provides written notice of non-renewal to the other party at least six months prior to the expiration of any renewal term after the first renewal term or the Voltaren^® Gel Agreement is otherwise terminated in accordance with its terms. Among other standard and customary termination rights granted under the Voltaren^® Gel Agreement, the Voltaren^® Gel Agreement can be terminated by either party upon reasonable written notice, if either party has committed a material breach that has not been remedied within ninety (90) days from the giving of written notice. Endo may terminate the Voltaren^® Gel Agreement by written notice upon the occurrence of several events, including the launch in the United States of a generic to the Licensed Product. Novartis may terminate the Voltaren^® Gel Agreement upon reasonable written notice (1) if Endo fails to deliver a set percentage of the minimum Details in any given six-month period under the Voltaren^® Gel Agreement; or (2) on or after the launch in the United States of an OTC equivalent product by Novartis, its affiliates or any third party that does not result in the declassification of the Licensed Product as a prescription product, following which net sales in any six-month period under the Voltaren^® Gel Agreement are less than a certain defined dollar amount. Hind Healthcare Inc. In November 1998, Endo entered into a license agreement (the Hind License Agreement) with Hind Healthcare Inc. (Hind), for the sole and exclusive right to develop, use, market, promote and sell Lidoderm^® in the United States. Under the terms of the Hind License Agreement, Endo paid Hind approximately $10 million based upon the achievement of certain milestones and capitalized this amount as an intangible asset representing the fair value of these exclusive rights. In addition, Endo pays Hind nonrefundable royalties based on net sales of Lidoderm^®. 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 six month periods ended June 30, 2011 and 2010 we recorded $42.1 million and $42.0 million for these royalties to Hind, respectively, which we recorded as a reduction to net pharmaceutical product sales. At June 30, 2011 and December 31, 2010, $21.2 million and $23.0 million, respectively, is recorded as a royalty payable and included in accounts payable in the accompanying Condensed Consolidated Balance Sheets. In March 2002, we extended this license with Hind to cover Lidoderm^® in Canada and Mexico. Vernalis Development Limited In July 2004, we entered into a License Agreement with Vernalis Development Limited (Vernalis) under which Vernalis agreed to license, exclusively to us, rights to market frovatriptan succinate (Frova^®) in North America (the Vernalis License Agreement). Frova^® was launched June 2002 in the U.S. and indicated for the acute treatment of migraine headaches in adults. Under the terms of the Vernalis License Agreement, we paid Vernalis an upfront fee of $30 million and annual $15 million payments each in 2005 and 2006. We capitalized the $30 million up-front payment, the present value of the two $15 million anniversary payments. We are amortizing this intangible asset into cost of revenues on a straight-line basis over its estimated life of twelve and one-half years. In addition, Vernalis could receive one-time milestone payments for the achievement of 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. Beginning on January 1, 2007, we began paying royalties to Vernalis based on the net sales of Frova^®. The term of the license agreement is for the shorter of the time (i) that there are valid claims on the Vernalis patents covering Frova^® or there is market exclusivity granted by a regulatory authority, whichever is longer, or (ii) until the date on which a generic version of Frova^® is first offered, but in no event longer than 20 years. We can terminate the license agreement under certain circumstances, including upon one years' written notice. In July 2007, Vernalis and Endo entered into an Amendment (Amendment No. 3) to the License Agreement dated July 14, 2004. Under Amendment No. 3, Vernalis granted an exclusive license to Endo to make, have made, use, commercialize and have commercialized the product Frova^® in Canada, under the Canadian Trademark. In February 2008, we entered into Amendment No. 4 to the Vernalis License Agreement (Amendment No. 4). In addition to amending certain specific terms and conditions of the License Agreement, Amendment No. 4 sets forth an annual minimum net sales threshold such that no royalties will be due on annual U.S. net sales of Frova^® less than $85 million. Prior to this amendment, royalties were payable by us to Vernalis on all net sales of Frova^® in the United States. Now, once the annual minimum net sales amount is reached, royalty payments will be due only on the portion of annual net sales that exceed the $85 million threshold. The Population Council The Company markets certain of its products utilizing the hydrogel polymer technology pursuant to an agreement between Indevus (now, Endo Pharmaceuticals Solutions Inc.) and the Population Council. Unless earlier terminated by either party in the event of a material breach by the other party, the term of the agreement is the shorter of twenty-five years from October 1997 or until the date on which The Population Council receives approximately $40 million in payments from the Company. The Company is required to pay to The Population Council 3% of its net sales of Vantas^® and any polymer implant containing a luteinizing hormone-releasing hormone (LHRH) analog. We are also obligated to pay royalties to the Population Council ranging from 0.5% of net sales to 4% of net sales under certain conditions. We are also obligated to pay the Population Council 30% of certain profits and payments received in certain territories by the Company from the licensing of Vantas^® or any other polymer implant containing an LHRH analog and 5% for other implants. Strakan International Limited In August 2009, we entered into a License and Supply Agreement with Strakan International Limited, a subsidiary of ProStrakan Group plc. (ProStrakan), for the exclusive right to commercialize Fortesta^TM Gel in the U.S. (the ProStrakan Agreement). Fortesta^TM Gel, a patented two percent (2%) testosterone transdermal gel for testosterone replacement therapy in male hypogonadism. A metered dose delivery system permits accurate dose adjustment to increase the ability to individualize patient treatment. Under the terms of the ProStrakan Agreement, Endo paid ProStrakan an up-front cash payment of $10 million, which was recorded as research and development expense. The Company received FDA approval in December 2010, which triggered a one-time approval milestone to ProStrakan for $12.5 million. The approval milestone was recorded as an intangible asset and is being amortized into cost of revenues on a straight-line basis over its estimated useful life. An additional milestone payment of $7.5 million was triggered during the second quarter of 2011 pursuant to the terms of the ProStrakan Agreement. The $7.5 million milestone was recorded to cost of revenues for the three months ended June 30, 2011. ProStrakan could potentially receive up to approximately $167.5 million in additional payments linked to the achievement of future commercial milestones related to Fortesta^TM Gel. ProStrakan will exclusively supply Fortesta^TM Gel to Endo at a supply price based on a percentage of annual net sales subject to a minimum floor price as defined in the ProStrakan Agreement. Endo may terminate the ProStrakan Agreement upon six months' prior written notice at no cost to the Company. *Products in Development* Grünenthal GMBH In February 2009, we entered into a Development, License and Supply Agreement (the Grünenthal Agreement) with Grünenthal GMBH (Grünenthal), granting us the exclusive right in North America to develop and market Grünenthal's investigational drug, axomadol. Currently in Phase II trials, axomadol is a patented new chemical entity being developed for the treatment of moderate to moderately-severe chronic pain and diabetic peripheral neuropathic pain. Under the terms of the Grünenthal Agreement, Endo paid Grünenthal approximately $9.4 million upfront and an additional $25.2 million in 2009 upon the achievement of certain milestones. We could be obligated to pay additional clinical, regulatory and approval milestone payments of up to approximately 6.3 million euros (approximately $9.1 million at June 30, 2011) and possibly development and commerce milestone payments of up to an additional $68.0 million. In addition, Grünenthal will receive payments from Endo based on a percentage of Endo's annual net sales of the product in the United States and Canada. The Grünenthal Agreement will expire in its entirety on the date of (i) the 15th anniversary of the first commercial sale of the product; or (ii) the expiration of the last issued patent claiming or covering the product, or (iii) the expiration of exclusivity granted by the FDA for the product, whichever occurs later. Among other standard and customary termination rights granted under the Grünenthal Agreement, we may terminate the Grünenthal Agreement at our sole discretion at any time upon ninety (90) days' written prior notice to Grünenthal and payment of certain penalties. In June 2011, we announced topline results from a Phase II study comparing the novel investigational drug axomadol against placebo in the treatment of patients with moderate to severe chronic lower back pain. The results indicate that axomadol did not meet predetermined study end points. The company is currently completing additional analyses of the data and evaluating the path forward for the program. In December 2007, we entered into a license, development and supply agreement with Grünenthal for the exclusive clinical development and commercialization rights in Canada and the United States for a new oral formulation of long-acting oxymorphone, which is designed to be crush resistant. Under the terms of this agreement Grünenthal is responsible for development efforts to conduct pharmaceutical formulation development and will manufacture any such product or products which obtain FDA approval. Endo is responsible for conducting clinical development activities and for all development costs incurred to obtain regulatory approval. Under the terms of the agreement, we paid approximately $4.9 million for the successful completion of a clinical milestone in 2010, which was recorded as research and development expense. Additional payments of approximately 59.2 million euros (approximately $85.2 million at June 30, 2011) may become due upon achievement of predetermined regulatory and commercial milestones. Endo will also make payments to Grünenthal based on net sales of any such product or products commercialized under this agreement. Impax Laboratories, Inc. In June 2010, the Company entered into a Development and Co-Promotion Agreement (the Impax Agreement) with Impax Laboratories, Inc. (Impax), whereby the Company was granted a royalty-free license for the co-exclusive rights to co-promote a next generation Parkinson's disease product. Under the terms of the Impax Agreement, Endo paid Impax an upfront payment of $10 million in 2010, which was recorded as research and development expense. The Company could be obligated to pay up to approximately $30 million in additional payments linked to the achievement of future clinical, regulatory, and commercial milestones related to the development product. Prior to the completion of Phase III trials, Endo may only terminate the Impax Agreement upon a material breach. Bioniche Life Sciences Inc. In July 2009, the Company entered into a License, Development and Supply Agreement (the Bioniche Agreement) with Bioniche Life Sciences Inc. and Bioniche Urology Inc. (collectively, Bioniche), whereby the Company licensed from Bioniche the exclusive rights to develop and market Bioniche's proprietary formulation of Mycobacterial Cell Wall-DNA Complex (MCC), known as Urocidin^TM, in the U.S. with an option for global rights. We exercised our option for global rights in the first quarter of 2010. Urocidin^TM is a patented formulation of MCC developed by Bioniche for the treatment of non-muscle-invasive bladder cancer that is currently undergoing Phase III clinical testing. Under the terms of the Bioniche Agreement, Endo paid Bioniche an up-front cash payment of $20.0 million in July 2009 and milestone payments of $4.0 million in 2010 resulting from the achievement of contractual milestones, both of which were recorded as research and development expense. In addition, Bioniche could potentially receive up to approximately $67.0 million and $29.0 million in additional payments linked to the achievement of future clinical, regulatory, and commercial milestones related to two separate indications for Urocidin^TM. Bioniche will manufacture Urocidin^TM and receive a transfer price for supply based on a percentage of Endo's annual net sales of Urocidin^TM. Endo may terminate the Bioniche Agreement upon 180 days' prior written notice. BayerSchering In July 2005, Indevus (now, Endo Pharmaceuticals Solutions Inc.) licensed exclusive U.S. rights from Schering AG, Germany, now BayerSchering Pharma AG (BayerSchering) to market a long-acting injectable testosterone preparation for the treatment of male hypogonadism that we refer to as Aveed^TM (the BayerSchering Agreement). The Company is responsible for the development and commercialization of Aveed^TM in the United States. BayerSchering is responsible for manufacturing and supplying the Company with finished product. As part of the BayerSchering Agreement, Indevus agreed to pay to BayerSchering up to $30.0 million in up-front, regulatory milestone, and commercialization milestone payments, including a $5.0 million payment due upon approval by the FDA to market Aveed^TM. Indevus also agreed to pay to BayerSchering 25% of net sales of Aveed^TM to cover both the cost of finished product and royalties. The BayerSchering Agreement expires ten years from the first commercial sale of Aveed^TM. Either party may also terminate the BayerSchering Agreement in the event of a material breach by the other party. In October 2006, Indevus entered into a supply agreement with BayerSchering pursuant to which BayerSchering agreed to manufacture and supply Indevus with all of its requirements for Aveed^TM for a supply price based on net sales of Aveed^TM. The supply price is applied against the 25% of net sales owed to BayerSchering pursuant to the BayerSchering Agreement. The BayerSchering Agreement expires ten years after the first commercial sale of Aveed^TM. Sanofi-Aventis In February 1994, Indevus (now, Endo Pharmaceuticals Solutions Inc.) licensed from Rhone-Poulenc Rorer, S.A., now Aventis Pharma S.A. (Sanofi-Aventis), exclusive, worldwide rights for the manufacture, use and sale of pagoclone under patent rights and know-how related to the drug, except that Indevus granted Sanofi-Aventis an option to sublicense, under certain conditions, rights to market pagoclone in France. Indevus paid Sanofi-Aventis a license fee and agreed to make milestone payments based on clinical and regulatory developments, and to pay royalties based on net sales through the expiration of the composition of matter patent. If sublicensed, the Company would pay to Sanofi-Aventis a portion of receipts from the sublicensee in lieu of payments. Under the terms of the agreement with Sanofi-Aventis, the Company is responsible for all costs of developing, manufacturing, and marketing pagoclone. This agreement expires with respect to each country upon the last to expire applicable patent. Additionally either party may also terminate this agreement in the event of a material breach by the other party. The Company could owe an additional $11.1 million if certain clinical and regulatory development milestones are achieved, as well as royalties on net sales or a percentage of royalties it receives if the product is sublicensed. Hydron Technologies, Inc. In November 1989, GP Strategies Corporation (GP Strategies), then known as National Patent Development Corporation, entered into an agreement (the Hydron Agreement) with Dento-Med Industries, Inc., now known as Hydron Technologies, Inc. In June 2000, Valera Pharmaceuticals, Inc. (Valera, now a wholly-owned subsidiary of the Company known as Endo Pharmaceuticals Valera Inc.) entered into a contribution agreement with GP Strategies, pursuant to which Valera acquired the assets of GP Strategies' drug delivery business, including all intellectual property, and all of GP Strategies' rights under the Hydron Agreement, and certain other agreements with The Population Council and Shire US, Inc. Pursuant to the Hydron Agreement, the Company has the exclusive right to manufacture, sell and distribute any prescription drug or medical device and certain other products made with hydrogel polymer technology. Hydron Technologies retained an exclusive, worldwide license to manufacture, market, or use products composed of, or produced with the use of, hydrogel polymer technology in certain consumer and oral health fields. Neither party is prohibited from manufacturing, exploiting, using or transferring the rights to any new non-prescription drug product containing hydrogel polymer technology, subject to certain exceptions, for limited exclusivity periods. Subject to certain conditions and exceptions, the Company is obligated to supply certain types of polymer to Hydron Technologies and Hydron Technologies is obligated to purchase such products from the Company. Under the Hydron Agreement, the Company also has the title to the Hydron^® trademark and must maintain such trademark throughout the world. The Company has decided to stop using the Hydron^® trademark and will transfer the title to such trademark to Hydron Technologies pursuant to the Hydron Agreement. This agreement continues indefinitely, unless terminated earlier by the parties. Each party may owe royalties up to 5% to the other party on certain products under certain conditions. Orion Corporation In January 2011, the Company entered into a Discovery, Development and Commercialization Agreement (the 2011 Orion Agreement) with Orion Corporation (Orion) to exclusively co-develop products for the treatment of certain cancers and solid tumors. Under the terms of the 2011 Orion Agreement, Endo and Orion each contributed four research programs to the collaboration to be conducted pursuant to the agreement. The development of each research program shall initially be the sole responsibility of the contributing party. However, upon the achievement of certain milestones, the non-contribution party shall have the opportunity to, at its option, obtain a license to jointly develop and commercialize any research program contributed by the other party for amounts defined in the 2011 Orion Agreement. Subject to certain limitations, upon the first commercial sale of any successfully launched jointly developed product, Endo shall be obligated to pay royalties to Orion based on net sales of the corresponding product in North America (the Endo territory) and Orion shall be obligated to pay royalties to Endo on net sales of the corresponding product in certain European countries (the Orion territory). The 2011 Orion Agreement shall expire in January 2016, unless terminated early or extended pursuant to the terms of the agreement. In January 2011, Endo exercised its option to obtain a license to jointly develop and commercialize Orion's Anti-Androgen program focused on castration-resistant prostate cancer, one of Orion's four contributed research programs, and made a corresponding payment to Orion for $10 million, which was expensed in the first quarter of 2011. Teva Pharmaceutical Industries Ltd On November 30, 2010 (the Qualitest Acquisition Date), Endo acquired Qualitest, who was party to an asset purchase agreement with Teva Pharmaceutical Industries Ltd (Teva) (the Teva Agreement). Pursuant to the Teva Agreement, Qualitest purchased certain pipeline generic products from Teva and could be obligated to pay consideration to Teva upon the achievement of certain future regulatory milestones. At June 30, 2011, the maximum amount we could be obligated to pay under the Teva Agreement is $12.5 million. EpiCept Corp. In December 2003, we entered into a license granting us exclusive, worldwide rights to certain patents of EpiCept Corp. (EpiCept) as well as exclusive, worldwide commercialization rights to EpiCept's LidoPAIN^® BP product (EpiCept Agreement). The EpiCept Agreement provides for Endo to pay EpiCept milestones as well as royalties on the net sales of EpiCept's LidoPAIN^® BP product. Under this Agreement, we made an upfront payment to EpiCept of $7.5 million which we capitalized as an intangible asset representing the fair value of the exclusive right and the patents. We are amortizing this intangible asset over its useful life of thirteen (13) years. EpiCept has also retained an option to co-promote the LidoPAIN^® BP product. Milestone payments made by Endo under this agreement, including regulatory milestones and sales thresholds, could total up to $82.5 million. In addition, the EpiCept Agreement also contains terms and conditions customary for this type of arrangement, including representations, warranties, indemnities and termination rights. The EpiCept Agreement generally lasts until the underlying patents expire. In January 2009, EpiCept announced that it was discontinuing all drug discovery activities including the development of LidoPAIN^® BP. However, the Company intends to maintain its patent rights conveyed by the EpiCept Agreement. Other We have entered into certain other collaboration and discovery agreements with third parties for the development of pain management and other products. These agreements require us to share in the development costs of such products and grant marketing rights to us for such products. We have also licensed from universities and other similar firms rights to certain technologies or intellectual property generally in the field of pain management. We are generally required to make upfront payments as well as other payments upon successful completion of regulatory or sales milestones. In addition, these agreements generally require us to pay royalties on sales of the products arising from these agreements. These agreements generally permit Endo to terminate the agreement with no significant continuing obligation. In July 2008, the Company made a $20 million investment in a privately-held company focused on the development of an innovative treatment for certain types of cancer. In exchange for our $20 million payment, we received an equity interest in the privately-held company. The Company's $20 million payment resulted in an ownership interest of less than 20% of the outstanding voting stock of the privately-held company. In addition, Endo and other equity holders have provided a line of credit totaling $25 million, of which Endo committed to fund $3 million. During 2010, $2.5 million was funded by Endo under the line-of credit, which could be converted into equity of the privately-held company upon certain events. During January of 2011, an additional payment of $0.3 million was subsequently funded under the same commitment. In March 2011, we received a $0.8 million distribution from our investment, which was recorded as a reduction to the investment balance. In June 2011, an additional payment of $0.7 million was subsequently funded under the same commitment. Based on the equity ownership structure, Endo does not have the ability to exert significant influence over the privately-held company. Pursuant to authoritative accounting guidance, our investment constitutes a variable interest in this privately-held company. We have determined that Endo is not the primary beneficiary and therefore have not consolidated the assets, liabilities, and results of operations of the privately-held company into our Condensed Consolidated Financial Statements. Accordingly, Endo is accounting for this investment under the cost method. As of June 30, 2011, our investment in the privately-held company was $22.7 million, representing our maximum exposure to loss.

License And Collaboration Agreements

NOTE 8. LICENSE AND COLLABORATION AGREEMENTS

Commercial Products

Novartis AG and Novartis Consumer Health, Inc.

On March 4, 2008, we entered into a License and Supply Agreement (the Voltaren^® Gel Agreement) with and among Novartis AG and Novartis Consumer Health, Inc (Novartis) to obtain the exclusive U.S. marketing rights for the prescription medicine Voltaren^® Gel (Voltaren^® Gel or Licensed Product). Voltaren^® Gel received regulatory approval in October 2007 from the U.S. Food and Drug Administration (the FDA), becoming the first topical prescription treatment for use in treating pain associated with osteoarthritis and the first new product approved in the U.S. for osteoarthritis since 2001. Voltaren^® Gel was granted marketing exclusivity in the U.S. as a prescription medicine until October 2010.

Under the terms of the five-year Voltaren^® Gel Agreement, Endo made an upfront cash payment of $85 million. Endo has agreed to pay royalties to Novartis on annual Net Sales of the Licensed Product, subject to certain thresholds as defined in the Voltaren^® Gel Agreement. In addition, Endo has agreed to make certain guaranteed minimum annual royalty payments of $30 million per year payable in the fourth and fifth year of the Voltaren^® Gel Agreement, subject to certain limitations including the launch of a generic to the Licensed Product in the United States. These guaranteed minimum royalties will be creditable against royalty payments on an annual basis such that Endo's obligation with respect to each year is to pay the greater of (i) royalties payable based on annual net sales of the Licensed Product or (ii) the guaranteed minimum royalty for such Voltaren^® Gel Agreement year. No royalty payments were made to Novartis during the three or six months ended June 30, 2011 or 2010. Novartis is also eligible to receive a one-time milestone payment of $25 million if annual net sales of Voltaren^® Gel exceed $300 million in the U.S. The $85 million upfront payment and the present value of the guaranteed minimum royalties have been capitalized as an intangible asset in the amount of $129 million, representing the fair value of the exclusive license to market Voltaren^® Gel. We are amortizing this intangible asset into cost of revenues over its estimated five-year useful life.

Endo is solely responsible to commercialize the Licensed Product during the term of the Voltaren^® Gel Agreement. With respect to each year during the term of the Voltaren^® Gel Agreement, Endo is required to incur a minimum amount of annual advertising and promotional expenses on the commercialization of the Licensed Product, subject to certain limitations. In addition, Endo is required to perform a minimum number of face-to-face one-on-one discussions with physicians and other healthcare practitioners (Details) for the purpose of promoting the Licensed Product within its approved indication during each year of the Voltaren^® Gel Agreement. Further, during the term of the Voltaren^® Gel Agreement, Endo will share in the costs of certain clinical studies and development activities initiated at the request of the FDA or as considered appropriate by Novartis and Endo.

During the term of the Voltaren^® Gel Agreement, Endo has agreed to purchase all of its requirements for the Licensed Product from Novartis. The price was fixed for the first year and subject to annual changes based upon changes in the producer price index and raw materials.

Novartis has the exclusive right, at its sole discretion, to effect a switch of the Licensed Product from a prescription product to an over-the-counter (OTC) product in the United States (an OTC Switch) by filing an amendment or supplement to the Licensed Product New Drug Application or taking any other action necessary or advisable in connection therewith to effect the OTC Switch, and thereafter to commercialize such OTC product. Notwithstanding the foregoing, Novartis shall not launch an OTC equivalent product prior to a time specified in the Voltaren^® Gel Agreement, and Novartis shall not take any action that results in the loss of the prescription product status for the Licensed Product prior to such time. Novartis will notify Endo if it submits a filing to the FDA in respect of an OTC equivalent product. In the event that Novartis gains approval of an OTC equivalent product that results in the Licensed Product being declassified as a prescription product, then Novartis will make certain royalty payments to Endo on net sales of such OTC equivalent product in the United States by Novartis, its affiliates and their respective licensees or sublicensees as set forth in the Voltaren^® Gel Agreement. As a condition to the payment of any and all such royalties, net sales of the Licensed Product in the United States must have exceeded a certain threshold prior to the launch of the OTC equivalent product by Novartis or its affiliates.

The initial term of the Voltaren^® Gel Agreement will expire on June 30, 2013. Endo has the option to extend the Voltaren^® Gel Agreement for two successive one year terms. The Voltaren^® Gel Agreement will remain in place after the first two renewal terms unless either party provides written notice of non-renewal to the other party at least six months prior to the expiration of any renewal term after the first renewal term or the Voltaren^® Gel Agreement is otherwise terminated in accordance with its terms. Among other standard and customary termination rights granted under the Voltaren^® Gel Agreement, the Voltaren^® Gel Agreement can be terminated by either party upon reasonable written notice, if either party has committed a material breach that has not been remedied within ninety (90) days from the giving of written notice. Endo may terminate the Voltaren^® Gel Agreement by written notice upon the occurrence of several events, including the launch in the United States of a generic to the Licensed Product. Novartis may terminate the Voltaren^® Gel Agreement upon reasonable written notice (1) if Endo fails to deliver a set percentage of the minimum Details in any given six-month period under the Voltaren^® Gel Agreement; or (2) on or after the launch in the United States of an OTC equivalent product by Novartis, its affiliates or any third party that does not result in the declassification of the Licensed Product as a prescription product, following which net sales in any six-month period under the Voltaren^® Gel Agreement are less than a certain defined dollar amount.

Hind Healthcare Inc.

In November 1998, Endo entered into a license agreement (the Hind License Agreement) with Hind Healthcare Inc. (Hind), for the sole and exclusive right to develop, use, market, promote and sell Lidoderm^® in the United States. Under the terms of the Hind License Agreement, Endo paid Hind approximately $10 million based upon the achievement of certain milestones and capitalized this amount as an intangible asset representing the fair value of these exclusive rights. In addition, Endo pays Hind nonrefundable royalties based on net sales of Lidoderm^®. 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 six month periods ended June 30, 2011 and 2010 we recorded $42.1 million and $42.0 million for these royalties to Hind, respectively, which we recorded as a reduction to net pharmaceutical product sales. At June 30, 2011 and December 31, 2010, $21.2 million and $23.0 million, respectively, is recorded as a royalty payable and included in accounts payable in the accompanying Condensed Consolidated Balance Sheets. In March 2002, we extended this license with Hind to cover Lidoderm^® in Canada and Mexico.

Vernalis Development Limited

In July 2004, we entered into a License Agreement with Vernalis Development Limited (Vernalis) under which Vernalis agreed to license, exclusively to us, rights to market frovatriptan succinate (Frova^®) in North America (the Vernalis License Agreement). Frova^® was launched June 2002 in the U.S. and indicated for the acute treatment of migraine headaches in adults. Under the terms of the Vernalis License Agreement, we paid Vernalis an upfront fee of $30 million and annual $15 million payments each in 2005 and 2006. We capitalized the $30 million up-front payment, the present value of the two $15 million anniversary payments. We are amortizing this intangible asset into cost of revenues on a straight-line basis over its estimated life of twelve and one-half years.

In addition, Vernalis could receive one-time milestone payments for the achievement of 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. Beginning on January 1, 2007, we began paying royalties to Vernalis based on the net sales of Frova^®. The term of the license agreement is for the shorter of the time (i) that there are valid claims on the Vernalis patents covering Frova^® or there is market exclusivity granted by a regulatory authority, whichever is longer, or (ii) until the date on which a generic version of Frova^® is first offered, but in no event longer than 20 years. We can terminate the license agreement under certain circumstances, including upon one years' written notice. In July 2007, Vernalis and Endo entered into an Amendment (Amendment No. 3) to the License Agreement dated July 14, 2004. Under Amendment No. 3, Vernalis granted an exclusive license to Endo to make, have made, use, commercialize and have commercialized the product Frova^® in Canada, under the Canadian Trademark.

In February 2008, we entered into Amendment No. 4 to the Vernalis License Agreement (Amendment No. 4). In addition to amending certain specific terms and conditions of the License Agreement, Amendment No. 4 sets forth an annual minimum net sales threshold such that no royalties will be due on annual U.S. net sales of Frova^® less than $85 million. Prior to this amendment, royalties were payable by us to Vernalis on all net sales of Frova^® in the United States. Now, once the annual minimum net sales amount is reached, royalty payments will be due only on the portion of annual net sales that exceed the $85 million threshold.

The Population Council

The Company markets certain of its products utilizing the hydrogel polymer technology pursuant to an agreement between Indevus (now, Endo Pharmaceuticals Solutions Inc.) and the Population Council. Unless earlier terminated by either party in the event of a material breach by the other party, the term of the agreement is the shorter of twenty-five years from October 1997 or until the date on which The Population Council receives approximately $40 million in payments from the Company. The Company is required to pay to The Population Council 3% of its net sales of Vantas^® and any polymer implant containing a luteinizing hormone-releasing hormone (LHRH) analog. We are also obligated to pay royalties to the Population Council ranging from 0.5% of net sales to 4% of net sales under certain conditions. We are also obligated to pay the Population Council 30% of certain profits and payments received in certain territories by the Company from the licensing of Vantas^® or any other polymer implant containing an LHRH analog and 5% for other implants.

Strakan International Limited

In August 2009, we entered into a License and Supply Agreement with Strakan International Limited, a subsidiary of ProStrakan Group plc. (ProStrakan), for the exclusive right to commercialize Fortesta^TM Gel in the U.S. (the ProStrakan Agreement). Fortesta^TM Gel, a patented two percent (2%) testosterone transdermal gel for testosterone replacement therapy in male hypogonadism. A metered dose delivery system permits accurate dose adjustment to increase the ability to individualize patient treatment. Under the terms of the ProStrakan Agreement, Endo paid ProStrakan an up-front cash payment of $10 million, which was recorded as research and development expense.

The Company received FDA approval in December 2010, which triggered a one-time approval milestone to ProStrakan for $12.5 million. The approval milestone was recorded as an intangible asset and is being amortized into cost of revenues on a straight-line basis over its estimated useful life. An additional milestone payment of $7.5 million was triggered during the second quarter of 2011 pursuant to the terms of the ProStrakan Agreement. The $7.5 million milestone was recorded to cost of revenues for the three months ended June 30, 2011. ProStrakan could potentially receive up to approximately $167.5 million in additional payments linked to the achievement of future commercial milestones related to Fortesta^TM Gel.

ProStrakan will exclusively supply Fortesta^TM Gel to Endo at a supply price based on a percentage of annual net sales subject to a minimum floor price as defined in the ProStrakan Agreement. Endo may terminate the ProStrakan Agreement upon six months' prior written notice at no cost to the Company.

Products in Development

Grünenthal GMBH

In February 2009, we entered into a Development, License and Supply Agreement (the Grünenthal Agreement) with Grünenthal GMBH (Grünenthal), granting us the exclusive right in North America to develop and market Grünenthal's investigational drug, axomadol. Currently in Phase II trials, axomadol is a patented new chemical entity being developed for the treatment of moderate to moderately-severe chronic pain and diabetic peripheral neuropathic pain. Under the terms of the Grünenthal Agreement, Endo paid Grünenthal approximately $9.4 million upfront and an additional $25.2 million in 2009 upon the achievement of certain milestones. We could be obligated to pay additional clinical, regulatory and approval milestone payments of up to approximately 6.3 million euros (approximately $9.1 million at June 30, 2011) and possibly development and commerce milestone payments of up to an additional $68.0 million. In addition, Grünenthal will receive payments from Endo based on a percentage of Endo's annual net sales of the product in the United States and Canada. The Grünenthal Agreement will expire in its entirety on the date of (i) the 15th anniversary of the first commercial sale of the product; or (ii) the expiration of the last issued patent claiming or covering the product, or (iii) the expiration of exclusivity granted by the FDA for the product, whichever occurs later. Among other standard and customary termination rights granted under the Grünenthal Agreement, we may terminate the Grünenthal Agreement at our sole discretion at any time upon ninety (90) days' written prior notice to Grünenthal and payment of certain penalties.

In June 2011, we announced topline results from a Phase II study comparing the novel investigational drug axomadol against placebo in the treatment of patients with moderate to severe chronic lower back pain. The results indicate that axomadol did not meet predetermined study end points. The company is currently completing additional analyses of the data and evaluating the path forward for the program.

In December 2007, we entered into a license, development and supply agreement with Grünenthal for the exclusive clinical development and commercialization rights in Canada and the United States for a new oral formulation of long-acting oxymorphone, which is designed to be crush resistant. Under the terms of this agreement Grünenthal is responsible for development efforts to conduct pharmaceutical formulation development and will manufacture any such product or products which obtain FDA approval. Endo is responsible for conducting clinical development activities and for all development costs incurred to obtain regulatory approval. Under the terms of the agreement, we paid approximately $4.9 million for the successful completion of a clinical milestone in 2010, which was recorded as research and development expense. Additional payments of approximately 59.2 million euros (approximately $85.2 million at June 30, 2011) may become due upon achievement of predetermined regulatory and commercial milestones. Endo will also make payments to Grünenthal based on net sales of any such product or products commercialized under this agreement.

Impax Laboratories, Inc.

In June 2010, the Company entered into a Development and Co-Promotion Agreement (the Impax Agreement) with Impax Laboratories, Inc. (Impax), whereby the Company was granted a royalty-free license for the co-exclusive rights to co-promote a next generation Parkinson's disease product. Under the terms of the Impax Agreement, Endo paid Impax an upfront payment of $10 million in 2010, which was recorded as research and development expense. The Company could be obligated to pay up to approximately $30 million in additional payments linked to the achievement of future clinical, regulatory, and commercial milestones related to the development product. Prior to the completion of Phase III trials, Endo may only terminate the Impax Agreement upon a material breach.

Bioniche Life Sciences Inc.

In July 2009, the Company entered into a License, Development and Supply Agreement (the Bioniche Agreement) with Bioniche Life Sciences Inc. and Bioniche Urology Inc. (collectively, Bioniche), whereby the Company licensed from Bioniche the exclusive rights to develop and market Bioniche's proprietary formulation of Mycobacterial Cell Wall-DNA Complex (MCC), known as Urocidin^TM, in the U.S. with an option for global rights. We exercised our option for global rights in the first quarter of 2010. Urocidin^TM is a patented formulation of MCC developed by Bioniche for the treatment of non-muscle-invasive bladder cancer that is currently undergoing Phase III clinical testing. Under the terms of the Bioniche Agreement, Endo paid Bioniche an up-front cash payment of $20.0 million in July 2009 and milestone payments of $4.0 million in 2010 resulting from the achievement of contractual milestones, both of which were recorded as research and development expense. In addition, Bioniche could potentially receive up to approximately $67.0 million and $29.0 million in additional payments linked to the achievement of future clinical, regulatory, and commercial milestones related to two separate indications for Urocidin^TM. Bioniche will manufacture Urocidin^TM and receive a transfer price for supply based on a percentage of Endo's annual net sales of Urocidin^TM. Endo may terminate the Bioniche Agreement upon 180 days' prior written notice.

BayerSchering

In July 2005, Indevus (now, Endo Pharmaceuticals Solutions Inc.) licensed exclusive U.S. rights from Schering AG, Germany, now BayerSchering Pharma AG (BayerSchering) to market a long-acting injectable testosterone preparation for the treatment of male hypogonadism that we refer to as Aveed^TM (the BayerSchering Agreement). The Company is responsible for the development and commercialization of Aveed^TM in the United States. BayerSchering is responsible for manufacturing and supplying the Company with finished product. As part of the BayerSchering Agreement, Indevus agreed to pay to BayerSchering up to $30.0 million in up-front, regulatory milestone, and commercialization milestone payments, including a $5.0 million payment due upon approval by the FDA to market Aveed^TM. Indevus also agreed to pay to BayerSchering 25% of net sales of Aveed^TM to cover both the cost of finished product and royalties. The BayerSchering Agreement expires ten years from the first commercial sale of Aveed^TM. Either party may also terminate the BayerSchering Agreement in the event of a material breach by the other party.

In October 2006, Indevus entered into a supply agreement with BayerSchering pursuant to which BayerSchering agreed to manufacture and supply Indevus with all of its requirements for Aveed^TM for a supply price based on net sales of Aveed^TM. The supply price is applied against the 25% of net sales owed to BayerSchering pursuant to the BayerSchering Agreement. The BayerSchering Agreement expires ten years after the first commercial sale of Aveed^TM.

Sanofi-Aventis

In February 1994, Indevus (now, Endo Pharmaceuticals Solutions Inc.) licensed from Rhone-Poulenc Rorer, S.A., now Aventis Pharma S.A. (Sanofi-Aventis), exclusive, worldwide rights for the manufacture, use and sale of pagoclone under patent rights and know-how related to the drug, except that Indevus granted Sanofi-Aventis an option to sublicense, under certain conditions, rights to market pagoclone in France. Indevus paid Sanofi-Aventis a license fee and agreed to make milestone payments based on clinical and regulatory developments, and to pay royalties based on net sales through the expiration of the composition of matter patent. If sublicensed, the Company would pay to Sanofi-Aventis a portion of receipts from the sublicensee in lieu of payments. Under the terms of the agreement with Sanofi-Aventis, the Company is responsible for all costs of developing, manufacturing, and marketing pagoclone. This agreement expires with respect to each country upon the last to expire applicable patent. Additionally either party may also terminate this agreement in the event of a material breach by the other party. The Company could owe an additional $11.1 million if certain clinical and regulatory development milestones are achieved, as well as royalties on net sales or a percentage of royalties it receives if the product is sublicensed.

Hydron Technologies, Inc.

In November 1989, GP Strategies Corporation (GP Strategies), then known as National Patent Development Corporation, entered into an agreement (the Hydron Agreement) with Dento-Med Industries, Inc., now known as Hydron Technologies, Inc. In June 2000, Valera Pharmaceuticals, Inc. (Valera, now a wholly-owned subsidiary of the Company known as Endo Pharmaceuticals Valera Inc.) entered into a contribution agreement with GP Strategies, pursuant to which Valera acquired the assets of GP Strategies' drug delivery business, including all intellectual property, and all of GP Strategies' rights under the Hydron Agreement, and certain other agreements with The Population Council and Shire US, Inc.

Pursuant to the Hydron Agreement, the Company has the exclusive right to manufacture, sell and distribute any prescription drug or medical device and certain other products made with hydrogel polymer technology. Hydron Technologies retained an exclusive, worldwide license to manufacture, market, or use products composed of, or produced with the use of, hydrogel polymer technology in certain consumer and oral health fields. Neither party is prohibited from manufacturing, exploiting, using or transferring the rights to any new non-prescription drug product containing hydrogel polymer technology, subject to certain exceptions, for limited exclusivity periods. Subject to certain conditions and exceptions, the Company is obligated to supply certain types of polymer to Hydron Technologies and Hydron Technologies is obligated to purchase such products from the Company. Under the Hydron Agreement, the Company also has the title to the Hydron^® trademark and must maintain such trademark throughout the world. The Company has decided to stop using the Hydron^® trademark and will transfer the title to such trademark to Hydron Technologies pursuant to the Hydron Agreement. This agreement continues indefinitely, unless terminated earlier by the parties. Each party may owe royalties up to 5% to the other party on certain products under certain conditions.

Orion Corporation

In January 2011, the Company entered into a Discovery, Development and Commercialization Agreement (the 2011 Orion Agreement) with Orion Corporation (Orion) to exclusively co-develop products for the treatment of certain cancers and solid tumors. Under the terms of the 2011 Orion Agreement, Endo and Orion each contributed four research programs to the collaboration to be conducted pursuant to the agreement. The development of each research program shall initially be the sole responsibility of the contributing party. However, upon the achievement of certain milestones, the non-contribution party shall have the opportunity to, at its option, obtain a license to jointly develop and commercialize any research program contributed by the other party for amounts defined in the 2011 Orion Agreement. Subject to certain limitations, upon the first commercial sale of any successfully launched jointly developed product, Endo shall be obligated to pay royalties to Orion based on net sales of the corresponding product in North America (the Endo territory) and Orion shall be obligated to pay royalties to Endo on net sales of the corresponding product in certain European countries (the Orion territory). The 2011 Orion Agreement shall expire in January 2016, unless terminated early or extended pursuant to the terms of the agreement. In January 2011, Endo exercised its option to obtain a license to jointly develop and commercialize Orion's Anti-Androgen program focused on castration-resistant prostate cancer, one of Orion's four contributed research programs, and made a corresponding payment to Orion for $10 million, which was expensed in the first quarter of 2011.

Teva Pharmaceutical Industries Ltd

On November 30, 2010 (the Qualitest Acquisition Date), Endo acquired Qualitest, who was party to an asset purchase agreement with Teva Pharmaceutical Industries Ltd (Teva) (the Teva Agreement). Pursuant to the Teva Agreement, Qualitest purchased certain pipeline generic products from Teva and could be obligated to pay consideration to Teva upon the achievement of certain future regulatory milestones. At June 30, 2011, the maximum amount we could be obligated to pay under the Teva Agreement is $12.5 million.

EpiCept Corp.

In December 2003, we entered into a license granting us exclusive, worldwide rights to certain patents of EpiCept Corp. (EpiCept) as well as exclusive, worldwide commercialization rights to EpiCept's LidoPAIN^® BP product (EpiCept Agreement). The EpiCept Agreement provides for Endo to pay EpiCept milestones as well as royalties on the net sales of EpiCept's LidoPAIN^® BP product. Under this Agreement, we made an upfront payment to EpiCept of $7.5 million which we capitalized as an intangible asset representing the fair value of the exclusive right and the patents. We are amortizing this intangible asset over its useful life of thirteen (13) years. EpiCept has also retained an option to co-promote the LidoPAIN^® BP product. Milestone payments made by Endo under this agreement, including regulatory milestones and sales thresholds, could total up to $82.5 million. In addition, the EpiCept Agreement also contains terms and conditions customary for this type of arrangement, including representations, warranties, indemnities and termination rights. The EpiCept Agreement generally lasts until the underlying patents expire. In January 2009, EpiCept announced that it was discontinuing all drug discovery activities including the development of LidoPAIN^® BP. However, the Company intends to maintain its patent rights conveyed by the EpiCept Agreement.

Other

We have entered into certain other collaboration and discovery agreements with third parties for the development of pain management and other products. These agreements require us to share in the development costs of such products and grant marketing rights to us for such products.

We have also licensed from universities and other similar firms rights to certain technologies or intellectual property generally in the field of pain management. We are generally required to make upfront payments as well as other payments upon successful completion of regulatory or sales milestones. In addition, these agreements generally require us to pay royalties on sales of the products arising from these agreements. These agreements generally permit Endo to terminate the agreement with no significant continuing obligation.

In July 2008, the Company made a $20 million investment in a privately-held company focused on the development of an innovative treatment for certain types of cancer. In exchange for our $20 million payment, we received an equity interest in the privately-held company. The Company's $20 million payment resulted in an ownership interest of less than 20% of the outstanding voting stock of the privately-held company. In addition, Endo and other equity holders have provided a line of credit totaling $25 million, of which Endo committed to fund $3 million. During 2010, $2.5 million was funded by Endo under the line-of credit, which could be converted into equity of the privately-held company upon certain events. During January of 2011, an additional payment of $0.3 million was subsequently funded under the same commitment. In March 2011, we received a $0.8 million distribution from our investment, which was recorded as a reduction to the investment balance. In June 2011, an additional payment of $0.7 million was subsequently funded under the same commitment. Based on the equity ownership structure, Endo does not have the ability to exert significant influence over the privately-held company. Pursuant to authoritative accounting guidance, our investment constitutes a variable interest in this privately-held company. We have determined that Endo is not the primary beneficiary and therefore have not consolidated the assets, liabilities, and results of operations of the privately-held company into our Condensed Consolidated Financial Statements. Accordingly, Endo is accounting for this investment under the cost method. As of June 30, 2011, our investment in the privately-held company was $22.7 million, representing our maximum exposure to loss.
