In the case of any sale of the Product for value other than in an arm’s length transaction exclusively for cash, such as barter or counter-trade, Net Sales shall be determined by referencing Net Sales at which substantially similar quantities of the Product are sold in an arm’s length transaction for cash.

Notwithstanding the foregoing, amounts billed by Asahi or its Affiliates for the sale of Product among Asahi or its Affiliates for resale shall not be included in the computation of Net Sales hereunder. Net Sales shall be accounted for in accordance with GAAP. Asahi and its Affiliates will sell the Product as a stand-alone product and will not sell the Product as part of a bundle with other products or offer package deals to customers that include the Product, except to the extent required to obtain sales contracts with government entities, and in such case, the price of the Product relevant for the calculation of Net Sales will be the average price in the preceding calendar quarter of the Product sold separately less the average discount of all products sold as part of the package.

Without limitation of the foregoing, each Party shall take any action reasonably requested by the other Party to prevent any potential breach of the BTC License Agreement. Asahi acknowledges and agrees that in furtherance of the foregoing, and notwithstanding the exclusive licenses granted to Asahi herein, BTC has the right to co-promote the Product in the Territory in accordance with Section 5.4 of the BTC License Agreement.

2.7.6 Jurisdictional Compliance. It is the desire and intent of the Parties that the restrictive covenants contained in this Section 2.7 be enforced to the fullest extent permissible under the Laws and public policies applied in each jurisdiction in which enforcement is sought. Auxilium and Asahi believe that the restrictive covenants in this Section 2.7 are valid and enforceable. However, if any restrictive covenant should for any reason become or be declared by a competent court or competition authority to be invalid or unenforceable in any jurisdiction, (i) the Party first gaining knowledge of such decision shall promptly notify the other Party thereof and (ii) such restrictive covenant shall be deemed to have been amended to the extent necessary in order that such provision be valid and enforceable.

faith) prior to distributing such Promotional Materials (for clarity, such samples need only be submitted for each different type of Promotional Material, as opposed to each item of Promotional Material needing to be submitted). Any new samples of Promotional Material for the Territory made thereafter will be provided to Auxilium for its review and comment (and Asahi shall consider any such comments in good faith). To the extent Asahi includes any Auxilium trademarks in the Promotional Materials for the Territory, Asahi shall comply with Auxilium’s then current guidelines for trademark usage.

Notwithstanding the foregoing, in the event that Asahi believes that the use or registration of the Product Trademark or the use of the Product Trade Dress in the Territory would be inappropriate due to linguistic or cultural particularities or against the Laws of the Territory, or in conflict with any Third Party’s intellectual property rights in the Territory, based on a review of market research, regulatory research, legal searches, investigation results, and any other relevant information that may have been collected by either Party that is relevant to the clearance for use and registration of a trademark or for use and registration of a trade dress, Asahi shall present such concern to Auxilium, and Asahi may propose an alternative trademark and trade dress to Auxilium for use and registration in the Territory; provided that, Auxilium shall have the right to approve the Product Trademark and the Product Trade Dress to be used in the Territory, such approval not to be unreasonably withheld. Auxilium shall bear all costs relating to the creation, legal clearance, filing, registration, and maintenance of any alternative trademark and trade dress.

Asahi (and its Affiliates) shall only use the Product Trademark and Product Trade Dress pursuant to the terms of this Agreement to identify and in connection with the Commercialization of the Product in the Territory for use in the Field, and Asahi shall not (and shall cause its Affiliates not to) use such Product Trademark or Product Trade Dress to identify, or subject to Section 6.7.4 in connection with the marketing of any other products.

Auxilium shall also own rights to any Internet domain names incorporating the Product Trademark or any variation or part of the Product Trademark as

Auxilium shall, at its sole discretion, have the first right to determine how to proceed with respect to such infringement, including by the institution of legal proceedings against such Third Party, in which case all costs and awards relating to such legal proceedings will be borne exclusively by Auxilium. If requested to do so, Asahi shall reasonably cooperate with any and all action initiated by Auxilium, including by joining legal proceedings as a party at Auxilium’s reasonable expense. If Auxilium elects not to take action or initiate legal proceedings against an instance of infringement to the Product Trademark or Product Trade Dress in the Territory, Asahi shall have the right at its own and sole discretion to take action or initiate legal proceedings against such instance of infringement to the Product Trademark or Product Trade Dress in the Territory, in which case all costs and awards relating to such legal proceeding will be borne exclusively by Asahi. If requested to do so, Auxilium shall reasonably cooperate with any and all action initiated by Asahi in connection therewith, including, by joining legal proceedings as a party at Asahi’s reasonable expense.

6.8.5 Trademark Acknowledgments. Each Party acknowledges the sole ownership by the other Party and validity of all copyright, trademarks, trade dress, logos and slogans owned by the other Party and used or intended to be used in connection with the Commercialization of the Product for the Field in the Territory. Each Party agrees that it will not at any time during or after the Term assert or claim any interest in, or do anything which may adversely affect the validity or enforceability of, any copyright, trademark, trade dress, logo or slogan owned by the other Party and used or intended to be used on or in connection with the marketing or sale of the Product.

6.9.1 Asahi shall own all marketing and sales data and information resulting from its Commercialization of the Product in the Field in the Territory (the “Commercialization Data”). Upon request from Auxilium, Asahi shall provide to Auxilium a copy of such of the Commercialization Data as constitutes promotional materials, marketing strategies and market research data (“Promotional Commercialization Data”). Auxilium shall have the right and license to use all such Promotional Commercialization Data (and the right to grant its Affiliates and Third Parties the right to use such Promotional Commercialization Data) in connection with its commercialization of the Product in the Field outside the Territory, which right and license shall survive the expiration or termination of this Agreement by Auxilium pursuant to Sections 13.2, 13.3 or 13.4.

To the extent Auxilium determines to utilize such Global Branding Strategy, Asahi shall use Commercially Reasonable Efforts to adhere to the Global Branding Strategy in its Commercialization of the Product, including with respect to any Promotional Materials; provided that, in the event that Asahi believes that the application of the Global Branding Strategy in the Territory would be inappropriate whether because of linguistic or cultural particularities, because it is against the Laws of the Territory or because Asahi reasonably determines it would be inconsistent with Asahi’s obligation to use Commercially Reasonable Efforts to Commercialize the Product in the Territory, Asahi shall present such concern to Auxilium, and the Parties shall discuss whether appropriate revisions to the Global Branding Strategy may make it appropriate for use in the Territory.

Notwithstanding the immediately preceding sentence and subject to Section 7.14, the Parties acknowledge and agree that the Units of Bulk Product per full production lot may vary in the future based on changes in yield; provided that, in the event of any such changes, Auxilium shall notify Asahi of such changes from time to time and such notification shall be deemed an amendment to the immediately preceding sentence in satisfaction of Section 16.1 hereof. The Parties recognize that the foregoing Forecasts may change over time based on commercial and regulatory developments and other factors, and Asahi shall be liable to reimburse Auxilium for Out-of-Pocket Costs incurred by Auxilium as a result of any such changes with respect to the

first three (3) quarters of the then current Forecast; provided, that, to the extent practicable, Auxilium shall use Commercially Reasonable Efforts to reduce such reimbursement exposure to Asahi under the terms hereof incident to changes in such Forecast; provided, however, that, notwithstanding the foregoing, in all cases, Auxilium shall not be in breach of this Agreement for any failure to reduce such reimbursement exposure and Asahi shall be responsible for purchasing any and all Bulk Product in accordance with the provisions of this Agreement.

7.6.2 Long Range Capacity Planning; Supply Chain Improvements. Concurrent with the Initial Forecast, for the purposes of discussion and planning of manufacturing capacity Asahi shall provide a non-binding forecast of Bulk Product needs for the twenty-four (24) months following that specified in the then current Forecast as described in Section 7.6.1 (“Long Range Forecast”). In the event Auxilium projects a shortfall in capacity based on the Long Range Forecast, the Parties will jointly discuss alternatives to increase such capacity, and the Parties shall promptly meet to discuss a reasonable manner of proceeding. Unless otherwise agreed to by the Parties during the Term, the Long Range Forecast shall be updated by Asahi and reviewed with Auxilium on an annual basis.

7.6.3 Orders. On each Forecast Date, in addition to the Forecast specified in Section 7.6.1, Asahi shall for the Term deliver to Auxilium a firm purchase order or orders specifying the quantities of the Bulk Product for delivery on a monthly basis in the calendar quarter beginning three (3) months after the Forecast Date, as well as the location of delivery and desired delivery date for each delivery (each a “Purchase Order”). Each such Purchase Order shall provide for aggregate quantities for delivery in such quarter that are no less than seventy-five percent (75%), and no more than one hundred twenty five percent (125%), of the quantities contained in the Forecast for such quarter given one (1) quarter earlier than the Forecast Date on which such Purchase Order is placed (see Schedule 7.6 for Forecast methodology). Unless agreed separately between the Parties, each Purchase Order shall specify no more than one (1) delivery date for the Bulk Product in each calendar month and not less than ninety (90) days from the Purchase Order Acceptance Date.

7.6.4 Receipt and Acceptance. Asahi shall purchase all Bulk Product ordered and specified in a Purchase Order. Purchase Orders may be delivered electronically or by other means to such location as Auxilium shall designate and shall be in a form reasonably acceptable to Auxilium. Auxilium shall provide written confirmation of such Purchase Order to Asahi within ten (10) business days of receipt of such Purchase Order (the date of such written confirmation, the “Purchase Order Acceptance Date”). Auxilium shall accept any Purchase Order for Bulk Product that does not exceed the applicable maximum provided for in the most recent Forecast. If a Purchase Order, whether or not accepted, exceeds such applicable maximum, the Parties shall seek to agree on a reasonable manner of proceeding. Auxilium shall use reasonable efforts to supply any amount of Bulk Product that Asahi orders pursuant to Section 7.6.3 in excess of the maximum amount deliverable under the ordering and forecasting procedures specified herein, but in any event, such efforts shall not be construed as an obligation hereunder and in no event shall Auxilium be deemed in breach of this Agreement by means of a failure to provide Bulk Product in excess of the Forecasted amount. Nothing in any such Purchase Order or written acceptance shall supersede the terms and conditions of this Agreement

EXECUTION VERSION

or the Quality Agreements, and in the event of a conflict between the terms such Purchase Order (or written acceptance, as applicable) and the terms of this Agreement (or the Quality Agreements, as applicable), the terms of this Agreement (or the Quality Agreements, as applicable) shall control. All Purchase Orders, written acceptances of Purchase Orders and other notices contemplated under this Section 7.6 shall be sent to the attention of such persons as each Party may identify to the other in writing from time to time in accordance with Section 16.3.

7.7 Pricing, Invoicing, and Manufacturing Standard Cost Audit.

7.7.1 Supply Delivery Price. The consideration payable by Asahi to Auxilium for the supply of Bulk Product for commercial sale and for the other rights granted to Asahi under this Agreement is contained in Section 8.3 as part of the Royalty Payments.

The Supply Delivery Price will be credited against future Royalty Payments as provided in Section 8.4.

7.7.2 Invoice. Each delivery of Bulk Product hereunder shall be accompanied by an invoice setting forth the Development Supply Price or the Supply Delivery Price, as applicable, for such delivery. Auxilium shall invoice such Bulk Product at the Development Supply Price or the Supply Delivery Price, as applicable, and Asahi will make payment against each invoice within fifty (50) days after delivery of invoice to Asahi, which invoice will accompany the Bulk Product covered by such invoice and delivered in accordance with Section 7.8.

7.7.3 Manufacturing Standard Cost Audit. Asahi shall have the right to audit the calculation of Auxilium’s prevailing Manufacturing Standard Cost of the Bulk Product. Such audit shall be carried out in the same manner as the audit provisions of Section 8.11 which shall apply mutatis mutandis to both Parties to facilitate such right of audit.

7.7.4 Royalty Rate and Supply Price Reduction. In the event that Asahi reasonably determines at anytime during the Term that any significant factor underlying Commercialization of the Product in the Field in the Territory has fundamentally changed in a manner that could not have been foreseen as of the Effective Date, so as to make it economically infeasible to incur the costs necessary to obtain and maintain Regulatory Approval for the Product for a given indication in the Field, then Asahi shall have the right to raise such concern at the next scheduled meeting of the JSC and the Parties shall discuss such fundamental changes and whether a reduction in the Supply Delivery Price or the Royalty Rate is appropriate; provided that, for clarity, nothing herein shall in any way obligate Auxilium to reduce the Supply Delivery Price or the Royalty Rate.

7.8 Shipping and Delivery.

7.8.1 Delivery. Auxilium shall deliver (or have delivered) to Asahi in accordance with this Section 7.8 the quantity of the Bulk Product specified in each accepted Purchase Order by the respective delivery date set forth in such Purchase Order or otherwise as agreed to by the Parties.

Asahi shall purchase all such Bulk Product so delivered.

7.8.2 Delivery Terms. Bulk Product shall be supplied to Asahi FCA (Auxilium’s or its designee’s site). Delivery shall occur, and title and risk of loss will pass to Asahi, when each order of the Product is placed at the disposal of Asahi at such Facility.

The Quality Agreements will set forth the Parties’ quality and compliance obligations with respect to Manufacture of the Product, and Auxilium’s quality and compliance obligations with respect to Manufacture of the Drug Substance used in the Product. Asahi and Auxilium agree to comply with the requirements and provisions set forth in the Quality Agreements. The Quality Agreements will set forth in greater detail many of the responsibilities and obligations set forth herein. In the event of a conflict between the terms of the Quality Agreements and the terms of this Agreement, the terms of this Agreement shall

CONFIDENTIAL

EXECUTION VERSION

prevail. The Parties shall execute the Quality Agreements within one-hundred eighty (180) days of the Effective Date, or such other time-frame as otherwise agreed between the Parties. To the extent required by Laws, in the event that Auxilium has a Third Party Manufacture Drug Substance or Product, Auxilium shall cause such Third Party to execute a quality agreement among Auxilium and Asahi detailing quality and compliance obligations of such Third Party with respect to Manufacture of the Drug Substance or the Product within one-hundred eighty (180) days of the Effective Date, or such other time-frame as otherwise agreed between the Parties, which in the event of a conflict between such Quality Agreement and the terms of this Agreement, the terms of this Agreement shall prevail.

7.9.2 Notice of Non-Conformance.

(a) Auxilium shall supply to Asahi the applicable batch number for the Bulk Product delivered as well as such other information as the Parties may set forth in the Quality Agreements with respect to the Manufacture of the Product (a “Manufacturing Certificate of Analysis”) for all Product shipped to Asahi hereunder. Asahi shall promptly on receipt of each shipment of Bulk Product hereunder inspect, or cause to have inspected, each shipment of the Product for any damage, defect or shortage and within a reasonable period of time give Auxilium written notice of any such damaged, defective or short shipment (a “Notice of Non-Conformance”).

(b) Latent Defects shall be communicated to Auxilium, together with appropriate detail, via a Notice of Non-Conformance, without undue delay after such Latent Defect is first discovered by Asahi (or Asahi otherwise is notified of such Latent Defect), but in all cases within five (5) business days of the date on which such Latent Defect was first discovered by Asahi or was notified to Asahi by the relevant Person discovering the defect, and thereafter such Latent Defect shall be handled as set forth in the remainder of this Section 7.9 and/or the Quality Agreements, as applicable. For purposes of this Section 7.9.2(b), “Latent Defects” shall mean those defects that could not be discovered by inspection by Asahi or its designee as described in Section 7.9.2(a).

7.9.3 Notification of significant quality issues. As set forth in the Quality Agreements, the Parties shall notify each other of the occurrence of a confirmed out-of specification (“OOS”) result or major process deviation relating to the Product and/or Drug Substance for use or sale in the Territory. Auxilium agrees to inform Asahi on all quality decisions regarding any OOS result or major process deviations involving the Bulk Product and/or Drug Substance.

7.9.4 Audits. Asahi shall have access to Auxilium’s or its Third Party manufacturer’s Facilities associated with the Product or Drug Substance at a mutually agreeable time for the sole purpose of auditing the Facilities for operational compliance with GMPs and the content of the respective Quality Agreements for Product and Drug Substance. The right to audit also includes any testing Facility related to the Product or Drug Substance, and any Facilities associated with raw materials, auxiliary materials, intermediates, container materials, and packing materials related to the Product or Drug Substance; provided that, to the extent a Third Party’s Facilities are the subject of an audit pursuant to this Section 7.9.4, Asahi shall (a)

CONFIDENTIAL

EXECUTION VERSION

perform such audit in conjunction with Auxilium (and any other licensees of Auxilium desiring to so audit), (b) bear any costs charged by such Third Party associated with such audit, and (c) abide by any applicable terms and conditions regarding such audit as Auxilium’s agreement with such Third Party may provide (including any limitations on the number of such audits as may be conducted in a given time-frame). For clarity, Auxilium shall have the right to accompany Asahi on any such audit of a Third Party Facility.

7.10 Disputes and Remedies.

7.10.1 Disputes. If Asahi delivers a Notice of Non-Conformance in respect of all or any part of a shipment of the Bulk Product, and Auxilium does not agree with Asahi’s determination that the Bulk Product fails to meet the Product Specifications for the Bulk Product (or there is a short shipment), the Parties shall in good faith attempt to resolve such dispute. Auxilium and Asahi shall have thirty (30) days, unless otherwise agreed in writing by the Parties, from the date of Auxilium’s receipt of a Notice of Non-Conformance to resolve such dispute regarding whether all or any part of such shipment of Bulk Product was Manufactured in conformance with the Product Specifications for the Bulk Product (or there is otherwise a short shipment). If the dispute regarding whether all or any part of a shipment of Bulk Product rejected by Asahi was Manufactured in conformance with the Product Specifications for the Bulk Product (or there is a short shipment) is not resolved in such thirty (30) day period, then Auxilium shall prepare an investigative report concerning such alleged non-conformance and such investigative report and Asahi’s original Notice of Non-Conformance shall be submitted to an independent consultant. The consultant shall be mutually agreed upon in writing by the Parties. The results of the consultant’s determination shall be based on Auxilium’s investigative report and Asahi’s original Notice of Non-Conformance and shall be final and binding on the Parties, and if such Bulk Product is determined to meet the Product Specifications for the Bulk Product (or is otherwise determined not to be a short shipment, as applicable), then Asahi shall pay for the costs of such consultant; otherwise Auxilium shall pay for such costs.

7.10.2 Remedies. In the event any shipment of Bulk Product is rejected pursuant to this Section 7.10 and/or the Quality Agreements, as applicable, solely as a result of any act or omission of Auxilium or its Third Party manufacturer, then (i) Asahi shall, at the direction of Auxilium, either (a) destroy such rejected Bulk Product at Auxilium’s reasonable expense (in accordance with Laws) or (b) return such Bulk Product to Auxilium, at a location designated by Auxilium and at Auxilium’s reasonable expense, and (ii) Auxilium, at no expense to Asahi, shall (in Asahi’s sole discretion) either (a) use its Commercially Reasonable Efforts to replace such non-conforming Bulk Product (or short shipment) or (b) give Asahi a credit in an amount equal to the amount paid or payable by Asahi with respect to such rejected Bulk Product (or short shipment). In the event that any shipment of Bulk Product is rejected for any other reason, Auxilium shall have no liability to Asahi in connection therewith, and Asahi shall, at its sole cost, destroy such rejected Bulk Product in compliance with Laws. SUBJECT TO SECTION 11.1, AUXILIUM’S LIABILITY IN RESPECT OF ANY REJECTION (INCLUDING ANY SHORT SHIPMENT) SHALL BE LIMITED TO THE REMEDIES PROVIDED IN THIS SECTION 7.10.2.

7.11 Shortages.

7.11.1 General. In the event that Auxilium anticipates the materials and/or Manufacturing capacity of Auxilium or its Third Party manufacturer required to Manufacture and deliver the Bulk Product to Asahi is to be in short supply, Auxilium shall promptly notify Asahi of such shortage and, the Parties shall promptly meet to discuss the shortage. Auxilium shall provide a written plan of action stating in reasonable detail the root cause of the shortage and proposed measures to remedy the shortage and the date such shortage is expected to end. Notwithstanding anything to the contrary contained herein, the situation where the commercial success of the Product in the Territory is the reason for such shortage (which situation is addressed in Section 7.6.2) shall not constitute a “shortage” or mean that Auxilium is “unable to supply” for purposes of this Section 7.11 (provided, that Auxilium is using Commercially Reasonable Efforts to supply all of Asahi’s Purchase Orders in accordance with this Agreement, including the allocation set forth in this Section 7.11.1). Auxilium shall use its Commercially Reasonable Efforts to minimize the duration of any shortage. During any such shortage, Auxilium shall allocate the materials and resources used in the supply of the Bulk Product between Auxilium (and any other Third Parties), on the one hand, and Asahi, on the other hand (subject to pre-existing obligations to Third Parties), (i) for the first two (2) years from the First Commercial Sale, based on, in the case of Asahi, the lesser of twenty-five percent (25%) of available Bulk Product (subject to pre-existing obligations to Third Parties) or the undelivered quantities specified in all then current Purchase Orders, (ii) following the second anniversary of the First Commercial Sale, the forecasted demand reported one quarter earlier (pursuant to Section 7.6) against the forecasted needs of Auxilium (and any Third Parties) and (iii) following the third anniversary of the First Commercial Sale, in accordance with their respective share of sales in the applicable market of the Product during the immediately preceding twelve (12) months. If, during the Term, Auxilium is unable to supply according to the terms of this Agreement at least sixty-five percent (65%) of the aggregate quantity of Bulk Product to be delivered as required by Asahi’s Purchase Orders (which have been properly submitted in accordance with this Agreement) (such quantity of Product, the “Minimum Delivery Amount”), other than to the extent caused by a Force Majeure Event or an act or omission of Asahi or any of its Affiliates, then Asahi will inform Auxilium in writing thereof. Following receipt of such notice, a joint team shall be promptly formed to address the nature of the shortage. Auxilium shall have ninety (90) days following receipt of such notice to supply Asahi with sufficient quantities of Bulk Product such that Auxilium shall have delivered the Minimum Delivery Amount for the applicable period (the “Minimum Delivery Cure Period”), and in the event that Auxilium is unable to supply such quantities of Bulk Product to meet the Minimum Delivery Amount within such Minimum Delivery Cure Period, then until such time as quantities of Bulk Product to meet the Minimum Delivery Amount are supplied to Asahi, the Royalty Rate will be reduced by twenty five percent (25%) (i.e., reduced by one-fourth) for all Net Sales commencing with sales recorded in the month immediately following the month in which the end of the Minimum Deliver Cure Period occurred, and ending up to three (3) months following the month in which Auxilium has delivered quantities of Bulk Product sufficient to meet the Minimum Delivery Amount; provided, that, for clarity, such three (3) month period is solely intended to allow Asahi an opportunity to reestablish its inventory, and to the extent that Asahi is able to do so in less than such three (3) month period the Royalty Rate shall promptly revert to

CONFIDENTIAL

EXECUTION VERSION

the amounts currently set forth in Section 8.3; provided, further, that during such three (3) month period, Asahi shall have the right to submit Purchase Orders in excess of the twenty-five percent (25%) cap on increases from the previously forecasted amount for such period (provided, that, Auxilium shall not be obligated hereunder to fill such excess orders but shall use reasonable efforts to satisfy such excess orders); provided, further, that Auxilium’s inability to fill such excess orders shall not constitute a shortage hereunder; provided, further, that during the pendency of any such shortage, Auxilium shall agree to form a joint Asahi/Auxilium team responsible for overseeing the restoration of supply.

7.12 Manufacturing Supply Assurance. Auxilium shall use Commercially Reasonable Efforts, as the exclusive supplier of Bulk Product, to ensure for the duration of the Term of the Agreement that a reasonable measure of supply assurance be maintained.

7.12.1 Auxilium shall, as part of this obligation, use Commercially Reasonable Efforts to establish within twenty four (24) months of the First Commercial Sale a fully qualified, approved, and validated back-up Facility for the filling and finishing of Bulk Product.

7.12.2 Auxilium shall, as part of this obligation, use Commercially Reasonable Efforts to establish within forty-two months (42) months of the First Commercial Sale a fully qualified, approved, and validated back-up Facility for the Manufacturing of the Drug Substance.

7.13 Safety Stock Obligations. From and after the First Commercial Sale, Auxilium shall maintain a minimum of [**] of Drug Substance based on Asahi’s Purchase Orders for the preceding [**], plus or minus twenty-five percent (25%). Auxilium shall, at Asahi’s option, upon reasonable advanced written notice, allow Asahi to audit such safety stock during normal business hours no more than once annually. From and after the First Commercial Sale, Asahi shall maintain a stock of at least [**] of Finished Product or Bulk Product based on Asahi’s sales of Units of Product for the preceding [**], plus or minus twenty-five percent (25%). In the event that either Party becomes unable to maintain a safety stock of Drug Substance or Finished Product or Bulk Product, as applicable, equivalent to at least seventy-five percent (75%) of that required by this Section 7.13, the Parties shall meet to discuss ways to mitigate further erosion of supply assurance.

7.14 Product Specification and Manufacturing Changes. Product Specification (for the Bulk Product and for the Product), Drug Substance Specification, Facilities changes (including changes to any Third Party manufacturers) and Manufacturing changes (including changes to lot sizes), including those resulting from a request received by a Party from a Governmental Authority, or any changes that Auxilium may propose to make, shall be dealt with pursuant to the Quality Agreements; provided that all applicable Regulatory Materials shall be prepared and filed by the Parties in accordance with the provisions of ARTICLE 5.

7.15 Termination of Supply Obligations. Notwithstanding anything to the contrary contained herein, the obligations of Auxilium under this ARTICLE 7, including the obligations to Manufacture and supply Product to Asahi hereunder, and Asahi’s obligations to purchase solely from Auxilium, shall, so long as Auxilium desires to continue supplying the Product, continue after the end of the Royalty Term, under the terms and conditions set forth in Section

CONFIDENTIAL

EXECUTION VERSION

14.3.2 and upon reasonable terms and conditions (subject to those terms and conditions set forth in Section 14.3.2) to be agreed between the Parties. In the event that Asahi desires to continue Commercializing the Product and Auxilium desires to continue supplying the Product following the expiration of this Agreement, the Parties shall, at least twenty-four (24) months before the expiration of this Agreement, negotiate in good faith and execute a distinct manufacturing and supply agreement with the terms and conditions (including the terms and conditions set forth in Section 14.3.2) upon which Auxilium continues to Manufacture and supply, and Asahi continues to purchase, requirements of the Product from Auxilium. In the event that Auxilium does not desire to continue Manufacturing and supplying the Product, but Asahi desires to continue Commercializing the Product in the Field in the Territory, Auxilium shall grant to Asahi a non-exclusive license under the Auxilium Manufacturing Technology to enable Asahi to Manufacture or have Manufactured the Product under the terms and conditions set forth in Section 14.3.2.

7.16 Auxilium Notice. Auxilium shall provide Asahi with notice by E-mail or Facsimile within three (3) business days after becoming aware of any significant condition or incident, which shall include any event, occurrence, or circumstance, including any governmental or private action, which could reasonably be expected to materially impact Auxilium’s ability to perform its obligations under this Agreement.

8.4 Royalty Payments and Reports; Floor Price.

8.4.1 General. Asahi shall calculate all Royalty Payments payable to Auxilium pursuant to Section 8.3 with respect to Net Sales at the end of each calendar quarter, which amounts shall be converted to Dollars at such time in accordance with Section 8.7. Asahi shall provide a written estimate of Net Sales during the just ended calendar quarter within fifteen (15) days of the end of such calendar quarter. Thereafter, Asahi shall pay to Auxilium the Royalty Payment due for Net Sales during a given calendar quarter within forty-five (45) days following the end of such calendar quarter. Each Royalty Payment due to Auxilium shall be accompanied by (i) a statement of the amount of gross sales of the Product in the Territory during the applicable calendar quarter (such amounts expressed in local currency), (ii) an itemized calculation of Net Sales in the Territory, showing deductions provided for in the definition of “Net Sales” during such calendar quarter, (iii) a calculation of the amount of the Royalty Payment due on such Net Sales for such calendar quarter less any amounts already remitted in such calendar quarter (and permitted to be credited against Royalty Payments) in accordance with Section 7.7 hereof as the Supply Delivery Price and (iv) twice per Fiscal Year, any reconciliations necessary as a result of the issuance of any rebates and allowances in accordance with Section 1.55.5.

EXECUTION VERSION

intellectual property rights as a result of the Manufacture and sale of such Unit of Product, as applicable.

8.5 Third Party Royalties and Other Payments.

8.5.1 Certain Existing Obligations. Auxilium shall be solely responsible for the payment of any royalties, sublicense revenues, milestones or other payments due to Third Parties under the BTC License Agreement as applicable, on account of the sale of the Product by Asahi hereunder.

8.5.2 Licenses to New Necessary Patents. If Asahi determines that it is necessary to obtain a license under any Patent of a Third Party that would be infringed by the Development or Commercialization by Asahi of the Product, as the Product exists on the Effective Date (excluding, for the avoidance of doubt, any additional technology that may be combined or incorporated therewith, or any future improvements or enhancements to the Product) in the Territory for use in the Field (as defined on the Effective Date), other than those described in Section 8.5.1 necessary to make, use, sell, offer for sale or import the Product for sale in the Field in the Territory, then the Parties shall meet to discuss and determine which Party will be primarily responsible for the negotiation and execution of the corresponding license agreement; provided, however, that, notwithstanding the foregoing, Auxilium shall have the sole right to obtain a license, and negotiate and execute a license agreement, in connection with the Manufacture of the Product or with respect to any intellectual property applicable to the Product on a worldwide basis (and, provided, that at the request of Auxilium, any such license from a Third Party shall include a license to Auxilium and its sublicensees with respect to the Product outside the Territory (and/or outside the Field)) during the Term. Any amounts due under such Third Party license agreement with respect to sale of the Product in the Field in the Territory will be borne by Asahi; provided, however, that Asahi shall be entitled to deduct up to fifty percent (50%) of the royalties payable to such Third Party in any given calendar quarter (on account of the sale of the Product in the Field in the Territory) from the Royalty Payments thereafter made by Asahi to Auxilium hereunder; provided, however, that the Royalty Payments payable under Section 8.3 shall not be reduced in any such event in any given calendar quarter below fifty percent (50%) of the amounts set forth in Section 8.3.1 and 8.3.2, as applicable. To the extent that Auxilium obtains a license under such a Third Party license agreement to sell the Product outside the Territory or outside the Field in the Territory, any amounts due under such a Third Party license agreement with respect to the sale of the Product outside the Territory or outside the Field in the Territory will be borne solely by Auxilium. In no event shall a license be deemed to be “necessary” on a Third Party Patent that is not issued, literally infringed or has genuine issues of fact that raise a reasonable defense that such Patent is invalid or unenforceable.

8.5.3 Licenses to Other Patents. Except as provided in Sections 8.5.1 and 8.5.2, if Asahi desires to obtain a license under any Third Party’s Patents that are otherwise useful for the Development or Commercialization of Product in the Field in the Territory but not necessary for Development or Commercialization by Asahi of the Product as such Product exists on the Effective Date in the Territory for use in the Field (as defined on the Effective Date), then Asahi shall notify the JSC. To the extent that both Parties determine (in each such Party’s sole

CONFIDENTIAL

EXECUTION VERSION

discretion) to pursue such a license with respect to Product in the Field in the Territory, then Asahi shall be primarily responsible for the negotiation and execution of the corresponding license agreement and the Parties shall share equally (unless otherwise mutually agreed or as provided in the next sentence) all payments associated with any license fees, royalties and other amounts owed to the applicable Third Party for such license. Notwithstanding the foregoing, at the time a license opportunity is presented to the JSC, Auxilium may elect not to participate in the costs of such joint licensing opportunity with respect to the Product in the Field in the Territory. In such event Asahi may pursue such licensing opportunity and shall be responsible for one hundred percent (100%) of all payments associated with any license fees, royalties and other amounts owed to the applicable Third Party for such license, with no right to invoice Auxilium or offset such amounts against any amounts owed to Auxilium under this Agreement; provided that, in the event that Asahi decides to pursue such license in the Field within the Territory, then Auxilium will not be entitled to opt out of the obligation to contribute equally to all costs of such licensing opportunity in the Field within the Territory if Auxilium pursues the licensing of such opportunity outside of the Territory or outside the Field.

8.6 Taxes and Withholding.

8.6.1 VAT. The Parties agree to cooperate with one another and use reasonable efforts to ensure that value added tax or similar payment (“VAT”) in respect of any payments made by Asahi to Auxilium under this Agreement does not represent an unnecessary cost in respect of payments made under this Agreement. For purposes of clarity, all sums payable under this Agreement shall be exclusive of VAT. In the event that any VAT is owing in any jurisdiction in respect of any such payment, Asahi shall pay such VAT, and (i) if such VAT is owing as a result of any action by Asahi, including any assignment or sublicense (including, assignment to, or payment hereunder by, another Asahi-related entity or Affiliate), or any failure on the part of Asahi or its Affiliates to comply with applicable tax Laws or filing or record retention requirements, that has the effect of modifying the tax treatment of the Parties hereto, then the payment in respect of which such VAT is owing shall be made without deduction for or on account of such VAT to ensure that Auxilium receives a sum equal to the sum which it would have received had such VAT not been due or (ii) otherwise, such payment shall be made after deduction of such VAT. For the sake of clarity, any increase in payments to Auxilium under this Section 8.6 shall reflect only the incremental increase in VAT directly resulting from clause (i) above. In the event that any VAT is owing in any jurisdiction in respect of any such payment, Auxilium will provide to Asahi tax invoices showing the correct amount of VAT in respect of such payments hereunder.

8.6.2 Withholding Tax Matters. If Asahi is required to make a payment to Auxilium subject to a deduction of tax or withholding tax, the sum payable by Asahi (in respect of which such deduction or withholding is required to be made) shall be made to Auxilium after deduction of the amount required to be so deducted or withheld, which deducted or withheld amount shall be remitted in accordance with Laws. Any such withholding taxes required under Laws to be paid or withheld shall be an expense of, and borne solely by Auxilium, subject to Section 8.6.1 and the obligation of Asahi to assume the responsibility of such expense in the event that such expense arises as a result of any action by Asahi.

CONFIDENTIAL

EXECUTION VERSION

8.6.3 Tax Cooperation. To the extent Asahi is required to deduct and withhold taxes on any payments to Auxilium, Asahi shall pay the amounts of such taxes to the proper Governmental Authority in a timely manner and promptly transmit to Auxilium an official tax certificate or other evidence of such withholding sufficient to enable Auxilium to claim such payments of taxes. Auxilium shall provide to Asahi any tax forms that may be reasonably necessary in order for Asahi not to withhold tax or to withhold tax at a reduced rate under an applicable bilateral income tax treaty. Auxilium shall use reasonable efforts to provide any such tax forms to Asahi at least thirty (30) days prior to the due date for any payments for which Auxilium desires that Asahi apply a reduced withholding rate. Each Party shall provide the other with reasonable assistance to enable the recovery, as permitted by Laws, of withholding taxes, VAT, or similar obligations resulting from payments made under this Agreement, such recovery to be for the benefit of the Party bearing such withholding tax or VAT.

8.7 Currency Conversion. All payments hereunder shall be made in U.S. Dollars. For the purpose of calculating any sums due under, or otherwise reimbursable pursuant to, this Agreement (including the calculation of Net Sales expressed in currencies other than U.S. Dollars), any amount expressed in a foreign currency shall be converted into U.S. Dollars in a manner consistent with such Party’s normal practices used to prepare its audited financial statements for external reporting purposes, provided that such practices use a widely accepted source of published exchange rates.

8.8 General Payment Procedures. Unless otherwise expressly payable in certain time frames as provided in this Agreement (including Section 7.7.2), the receiving Party shall invoice the paying Party for all amounts due to such receiving Party under this Agreement, and such payments shall be made within forty-five (45) days following the receipt by the paying Party of an invoice from the receiving Party specifying the amount due.

8.9 Late Payments. Any amount required to be paid by a Party hereunder which is not paid on the date due shall bear interest at a rate equal to the thirty (30) day U.S. dollar LIBOR rate effective for the date that payment was first due as reported by The Wall Street Journal plus two percent (2%). Such interest shall be computed on the basis of a year of three hundred sixty (360) days for the actual number of days payment is delinquent.

8.10 Legal Restrictions. If at any time legal restrictions prevent the remittance by Asahi of all or any part of amounts due under this Agreement in the Territory, Asahi will have the right and option to make such payment by depositing the amount thereof in local currency to an account in the name of Auxilium in a bank or other depository in the Territory as directed by Auxilium. Asahi will consult with Auxilium regarding, and promptly notify Auxilium of, any and all such arrangements.

8.11 Records; Audits. Asahi and its Affiliates and subcontractors shall keep full, true and accurate records and books of account containing all particulars that may be necessary for the purpose of confirming the accuracy of, and calculating, as applicable, all Royalty Payments and other amounts payable to Auxilium hereunder (including records of Net Sales), and any other records reasonably required to be maintained with respect to Asahi’s obligations under this Agreement, for a minimum period of two (2) years or such longer period as required

by Laws. Auxilium shall have a right to request an audit of Asahi by an independent, internationally recognized accounting firm in order to confirm the accuracy of the foregoing (an “Audit”); provided, however, that Auxilium shall only have the right to request such Audit one time during any given calendar year. Upon the written request by Auxilium to Audit Asahi, Auxilium shall have the right to engage an independent, internationally recognized accounting firm to perform a review as is reasonably necessary to enable such accounting firm to calculate or otherwise confirm the accuracy of any of the foregoing for the calendar year(s) requested by Auxilium; provided that (i) such accountants shall be given access to, and shall be permitted to examine and copy such books and records of Asahi upon five (5) business days’ prior written notice to Asahi, and at all reasonable times on such business days, (ii) prior to any such examination taking place, such accountants shall enter into a confidentiality agreement with Asahi reasonably acceptable to Asahi in order to keep all information and data contained in such books and records strictly confidential and shall not disclose such information or copies of such books and records to any third person including Auxilium, but shall only use the same for the purpose of the reviews and/or calculations which they need to perform in order to determine any amounts being reviewed, and (iii) such accountants shall use reasonable efforts to minimize any disruption to Asahi’s business. Asahi shall make personnel reasonably available during regular business hours to answer queries on all such books and records required for the purpose of the Audit. The accountants shall deliver a copy of their findings to each of the Parties within ten (10) business days of the completion of the review, and, in the absence of fraud or manifest error, the findings of such accountant shall be final and binding on each of the Parties. Any underpayments by Asahi shall be paid to Auxilium within ten (10) business days of notification of the results of such inspection.

Each of the Parties shall promptly, but in any event no later than ten (10) days after receipt of notice thereof, notify the other Party in writing in the event of any claims by a Third Party of alleged patent infringement by Asahi or Auxilium or any of their respective Affiliates or, solely with respect to Auxilium, its sublicensees with respect to the research, development, manufacture, use, sale, offer for sale or importation of a Product (each, an “Infringement Claim”). With respect to any Infringement Claim in the Field in the Territory, the Parties shall attempt to negotiate in good faith a resolution with respect thereto. If the Parties cannot settle such Infringement Claim with the appropriate Third Parties within thirty (30) days after the receipt of the notice pursuant to this Section 9.4.1, then the following shall apply:

(a) In the case of any such Infringement Claim against Asahi alone or against both Asahi and Auxilium, in each case, with respect to the Product in the Field in the Territory, then Asahi shall be deemed to be the “Controlling Party” for purposes of such Infringement Claim. In the case of any Infringement Claim against (i) Auxilium alone, or (ii) with respect to the Product outside the Territory or outside the Field, then Auxilium shall be deemed to be the “Controlling Party” for purposes of such Infringement Claim. In the event of worldwide litigation (such that related cases and/or claims are being pursued both inside and

CONFIDENTIAL

EXECUTION VERSION

outside of the Territory), each Party shall reasonably assist the other in its role as the Controlling Party in its respective territory.

(b) The Controlling Party shall assume control of the defense of such Infringement Claim. The non-Controlling Party, upon request of the Controlling Party, agrees to join in any such litigation at the Controlling Party’s expense, and in any event to reasonably cooperate with the Controlling Party at the Controlling Party’s expense. The non-Controlling Party will have the right to consult with the Controlling Party concerning such Infringement Claim and to participate in and be represented by independent counsel in any litigation in which such non-Controlling Party is a party at its own expense. The Controlling Party shall have the exclusive right to settle any Infringement Claim without the consent of the other Party, unless such settlement shall have a material adverse impact on the other Party (in which case the consent of such other Party shall be required). For purposes of this Section 9.4.1(b), any settlement that would involve the waiver of rights (including the rights to receive payments) of such other Party shall be deemed a material adverse impact and shall require the consent of such other Party, such consent not to be unreasonably withheld.

(c) If a Party shall become engaged in or participate in any suit described in this Section 9.4.1, the other Party shall cooperate, and shall cause its and its Affiliates’ employees to cooperate, with such Party in all reasonable respects in connection therewith, including giving testimony and producing documents lawfully requested, and using its reasonable efforts to make available to the other, at no cost to the other (other than reimbursement of actually incurred, reasonable out-of-pocket travel and lodging expenses), such employees who may be helpful with respect to such suit, investigation, claim or other proceeding.

9.4.2 Prosecution of Infringers.

(a) Notice. If either Party (i) receives notice of any patent nullity actions, any declaratory judgment actions or any alleged or threatened infringement of patents or patent applications or misappropriation of intellectual property in the Territory comprising the (w) Joint Inventions or Joint Collaboration Patents, (x) Auxilium Patents, Auxilium Inventions or Auxilium Know-How or (y) Asahi Applied Patents, Asahi Inventions or Asahi Applied Know-How, or (ii) learns that a Third Party is infringing or allegedly infringing any Patent within the Auxilium Patents, Joint Collaboration Patents or Asahi Applied Patents in each case, in the Territory, or if any Third Party claims that any such Patent is invalid or unenforceable, in each case, with respect to the Field in the Territory, it shall promptly notify the other Party thereof, including providing evidence of infringement or the claim of invalidity or unenforceability reasonably available to such Party.

(b) Enforcement of Patents.

(i) As between Auxilium and Asahi, Asahi shall have the first right (but not the obligation) to take the appropriate steps to enforce or defend any Patent within the Auxilium Patents, Asahi Applied Patents and Joint Collaboration Patents against infringement by a Third Party that is conducting the manufacture, sale, use, offer for sale or import of any

pharmaceutical product in the Field in the Territory. Asahi may take steps including the initiation, prosecution and control of any suit, proceeding or other legal action by counsel of its own choice. Asahi shall bear the costs of such enforcement or defense, as applicable. Notwithstanding the foregoing, Auxilium will have the right, at its own expense, to be represented in any such action by counsel of its own choice.

(ii) If, pursuant to Section 9.4.2(b)(i), Asahi fails to institute such litigation or otherwise take steps to remedy the infringement of an Auxilium Patent, an Asahi Applied Patent or a Joint Collaboration Patent within one hundred eighty (180) days of the date one Party has provided notice to the other Party pursuant to Section 9.4.2(a) of such infringement or claim, then Auxilium shall have the right (but not the obligation), at its own expense, to bring any such suit, action or proceeding by counsel of its own choice and Asahi will have the right, at its own expense, to be represented in any such action by counsel of its own choice. Notwithstanding anything to the contrary contained herein, in no event shall Asahi have any right to bring any suit, action or proceeding with respect to any matter involving infringement of an Auxilium Manufacturing Patent, or a Patent outside the Territory or outside the Field.

(i) If one Party brings any suit, action or proceeding under Section 9.4.2(b), the other Party agrees to be joined as party plaintiff if necessary to prosecute the suit, action or proceeding and to give the first Party reasonable authority to file and prosecute the suit, action or proceeding; provided, however, that neither Party will be required to transfer any right, title or interest in or to any property to the other Party or any other party to confer standing on a Party hereunder.

(ii) The Party not pursuing the suit, action or proceeding hereunder will provide reasonable assistance to the other Party, including by providing access to relevant documents and other evidence and making its employees available, subject to the other Party’s reimbursement of any Out-of-Pocket Costs incurred by the non-enforcing or defending Party in providing such assistance.

(iii) Asahi shall not, without the prior written consent of Auxilium (in its sole discretion), enter into any compromise or settlement relating to any claim, suit or action that it brought under Section 9.4.2 involving an Auxilium Patent, an Asahi Applied Patent or a Joint Collaboration Patent, that admits the invalidity or unenforceability of any Auxilium Patent, Asahi Applied Patent or Joint Collaboration Patent, or requires Auxilium to pay any sum of money, or otherwise adversely affects the rights of Auxilium with respect to such Patents, the Product or Auxilium’s rights hereunder (including the rights to receive payments).

(iv) Any settlements, damages or other monetary awards (a “Recovery”) recovered pursuant to a suit, action or proceeding brought pursuant to Section 9.4.2(b) will be allocated first to the costs and expenses of the Party taking such action, and second, to the costs and expenses (if any) of the other Party, with any remaining amounts (if any) to be allocated as follows: (i) to the extent that such Recovery is a payment for lost sales of the Product in the Field in the Territory, (a) if Asahi is the Party taking such action, then Asahi shall

CONFIDENTIAL

EXECUTION VERSION

pay a Royalty Payment to Auxilium pursuant to Section 8.3 with respect to the imputed loss in Net Sales out of any such Recovery or (b) if Auxilium is the Party taking such action, then any such Recovery shall be shared equally by Auxilium and Asahi and (ii) all remaining Recoveries shall be payable to the Party taking such action to the extent such remaining Recoveries relate solely to the Product in the Field in the Territory (and, for purposes of clarity, all remaining Recoveries related to the Product outside the Field or outside the Territory shall be payable to Auxilium).

(d) Infringement and Defense of Auxilium Patents Outside of the Territory or Outside the Field. For clarity, with respect to any and all infringement or defense of any Auxilium Patent (including a Joint Collaboration Patent) anywhere outside of the Territory or outside the Field, Auxilium (or its designee) shall have the sole and exclusive right to bring an appropriate suit or other action against any Person engaged in such infringement or defense of any such Auxilium Patents (including any Joint Collaboration Patents), in its sole discretion and Asahi shall have no rights with respect thereto.

9.5 Patent Term Extensions. As between Auxilium and Asahi, Auxilium shall have the exclusive right, but not the obligation, to seek, in Asahi’s name if so required, Patent Term Extensions (including any supplemental protection certificates and the like available under applicable Law) in the Territory in relation to the Auxilium Patents (including Joint Collaboration Patents). Asahi and Auxilium shall cooperate in connection with all such activities. Auxilium, its agents and attorneys will give due consideration to all suggestions and comments of Asahi regarding any such activities, but in the event of a disagreement between the Parties, Auxilium shall have the final decision making authority.

11.2 Indemnification by Asahi. Asahi hereby agrees to save, indemnify, defend and hold Auxilium, its Affiliates, and their respective directors, agents and employees harmless from and against any and all Losses arising in connection with any and all Third Party Claims resulting or otherwise arising from (i) any breach by Asahi (or by any of its Affiliates, wholesalers or distributors) of any of its representations, warranties, covenants or obligations pursuant to this Agreement, (ii) the negligence or willful misconduct by Asahi or its Affiliates, wholesalers or distributors or their respective officers, directors, employees, agents or consultants in performing any obligations under this Agreement, or (iii) any matter related to the Development, Packaging and Labeling or Commercialization of the Product hereunder (including, for clarity, any product liability Losses resulting therefrom) by Asahi or its Affiliates wholesalers or distributors or their respective officers, directors, employees, agents or consultants; in each case except to the extent that such Losses are subject to indemnification by Auxilium pursuant to Section 11.1.

11.3 Indemnification Procedures.

11.3.1 Notice of Claim. All indemnification claims in respect of any indemnitee seeking indemnity under Section 11.1 or 11.2, as applicable (collectively, the “Indemnitees” and each an “Indemnitee”) will be made solely by the corresponding Party (the “Indemnified Party”). The Indemnified Party will give the indemnifying Party (the “Indemnifying Party”) prompt written notice (an “Indemnification Claim Notice”) of any Losses and any legal proceeding initiated by a Third Party against the Indemnified Party as to which the Indemnified Party intends to make a request for indemnification under Section 11.1 or 11.2, as applicable, but in no event will the Indemnifying Party be liable for any Losses that result from any delay in providing such notice which materially prejudices the defense of such proceeding. Each Indemnification Claim Notice shall contain a description of the claim and the nature and amount

CONFIDENTIAL

EXECUTION VERSION

of such Loss (to the extent that the nature and amount of such Loss are known at such time). Together with the Indemnification Claim Notice, the Indemnified Party will furnish promptly to the Indemnifying Party copies of all notices and documents (including court papers) received by any Indemnitee in connection with the Third Party Claim.

11.3.2 Control of Defense. At its option, the Indemnifying Party may assume the defense of any Third Party Claim subject to indemnification as provided for in Section 11.1 or 11.2, as applicable, by giving written notice to the Indemnified Party within thirty (30) days after the Indemnifying Party’s receipt of an Indemnification Claim Notice. Upon assuming the defense of a Third Party Claim, the Indemnifying Party may appoint as lead counsel in the defense of the Third Party Claim any legal counsel it selects, and such Indemnifying Party shall thereafter continue to defend such Third Party Claim in good faith. Should the Indemnifying Party assume the defense of a Third Party Claim (and continue to defend such Third Party Claim in good faith), the Indemnifying Party will not be liable to the Indemnified Party or any other Indemnitee for any legal expenses subsequently incurred by such Indemnified Party or other Indemnitee in connection with the analysis, defense or settlement of the Third Party Claim, unless the Indemnifying Party has failed to assume the defense and employ counsel in accordance with this Section 11.3.

11.3.3 Right to Participate in Defense. Without limiting Section 11.3.2, any Indemnitee will be entitled to participate in the defense of a Third Party Claim for which it has sought indemnification hereunder and to employ counsel of its choice for such purpose; provided, however, that such employment will be at the Indemnitee’s own expense unless (i) the employment thereof has been specifically authorized by the Indemnifying Party in writing, or (ii) the Indemnifying Party has failed to assume the defense (or continue to defend such Third Party Claim in good faith) and employ counsel in accordance with this Section 11.3, in which case the Indemnified Party will be allowed to control the defense.

11.3.4 Settlement. With respect to any Losses relating solely to the payment of money damages in connection with a Third Party Claim and that will not result in the Indemnitee becoming subject to injunctive or other relief or otherwise adversely affect the business of the Indemnitee in any manner, and as to which the Indemnifying Party will have acknowledged in writing the obligation to indemnify the Indemnitee hereunder, the Indemnifying Party will have the sole right to consent to the entry of any judgment, enter into any settlement or otherwise dispose of such Loss, on such terms as the Indemnifying Party, in its reasonable discretion, will deem appropriate (provided, however, that such terms shall include a complete and unconditional release of the Indemnified Party from all liability with respect thereto), and will transfer to the Indemnified Party all amounts which said Indemnified Party will be liable to pay prior to the time of the entry of judgment. With respect to all other Losses in connection with Third Party Claims, where the Indemnifying Party has assumed the defense of the Third Party Claim in accordance with Section 11.3.2, the Indemnifying Party will have authority to consent to the entry of any judgment, enter into any settlement or otherwise dispose of such Loss, provided it obtains the prior written consent of the Indemnified Party (which consent will be at the Indemnified Party’s reasonable discretion). The Indemnifying Party that has assumed the defense of (and continues to defend) the Third Party Claim in accordance with Section 11.3.2

CONFIDENTIAL

EXECUTION VERSION

will not be liable for any settlement or other disposition of a Loss by an Indemnitee that is reached without the written consent of such Indemnifying Party. Regardless of whether the Indemnifying Party chooses to defend or prosecute any Third Party Claim, no Indemnitee will admit any liability with respect to, or settle, compromise or discharge, any Third Party Claim without first offering to the Indemnifying Party the opportunity to assume the defense of the Third Party Claim in accordance with Section 11.3.2.

11.3.5 Cooperation. If the Indemnifying Party chooses to defend or prosecute any Third Party Claim, the Indemnified Party will, and will cause each other Indemnitee to, cooperate in the defense or prosecution thereof and will furnish such records, information and testimony, provide such witnesses and attend such conferences, discovery proceedings, hearings, trials and appeals as may be reasonably requested in connection with such Third Party Claim. Such cooperation will include access during normal business hours afforded to the Indemnifying Party to, and reasonable retention by the Indemnified Party of, records and information that are reasonably relevant to such Third Party Claim, and making Indemnitees and other employees and agents available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder, and the Indemnifying Party will reimburse the Indemnified Party for all its reasonable out-of-pocket expenses incurred in connection with such cooperation.

11.3.6 Expenses of the Indemnified Party. Except as provided above, the reasonable and verifiable costs and expenses, including fees and disbursements of counsel, incurred by the Indemnified Party in connection with any Third Party Claim will be reimbursed on a calendar quarter basis by the Indemnifying Party, without prejudice to the Indemnifying Party’s right to contest the Indemnified Party’s right to indemnification and subject to refund in the event the Indemnifying Party is ultimately held not to be obligated to indemnify the Indemnified Party.

11.4 Limitation of Liability. NEITHER PARTY SHALL BE LIABLE TO THE OTHER FOR ANY CONSEQUENTIAL, INCIDENTAL, OR INDIRECT DAMAGES ARISING FROM OR RELATING TO ANY BREACH OF THIS AGREEMENT, REGARDLESS OF ANY NOTICE OF THE POSSIBILITY OF SUCH DAMAGES. NOTWITHSTANDING THE FOREGOING, NOTHING IN THIS SECTION 11.4 IS INTENDED TO OR SHALL LIMIT OR RESTRICT THE INDEMNIFICATION RIGHTS OR OBLIGATIONS OF ANY PARTY UNDER SECTION 11.1 OR 11.2, OR DAMAGES AVAILABLE FOR A PARTY’S BREACH OF CONFIDENTIALITY OBLIGATIONS UNDER ARTICLE 12.

Each Party shall provide the other Party with written evidence of such insurance prior to commencement of this Agreement (if requested by the other Party) and upon expiration of any one coverage. Each Party shall provide the other Party with written notice at least thirty (30) days prior to the cancellation, nonrenewal or material change in such insurance or self - insurance which materially adversely affects the rights of the other Party hereunder.

Schedule 12.5.1: Press Release

Auxilium Pharmaceuticals, Inc. and Asahi Kasei Pharma Corporation Enter Agreement

to Develop, Commercialize and Supply XIAFLEX^® In Japan

Asahi Kasei Obtains Exclusive Rights for Two Indications

Malvern, PA (March XX, 2011) — Auxilium Pharmaceuticals, Inc. (NASDAQ: AUXL) and Asahi Kasei Pharma Corporation announced today that they have entered into a long-term strategic alliance for the development, commercialization and supply of XIAFLEX^® (collagenase clostridium histolyticum), a novel, first-in-class biologic for the treatment of Dupuytren’s contracture and Peyronie’s disease. Under the terms of the agreement, Asahi Kasei Pharma will receive exclusive rights to commercialize XIAFLEX for the treatment of Dupuytren’s contracture and Peyronie’s disease in Japan. Asahi Kasei Pharma will be primarily responsible for the clinical development, regulatory and commercialization activities for XIAFLEX in Japan.

XIAFLEX has been approved by the U.S. Food and Drug Administration and the European Commission for the treatment of Dupuytren’s contracture. Asahi Kasei Pharma expects to begin clinical trials for XIAFLEX for the treatment of Dupuytren’s contracture in 2012. XIAFLEX is also being evaluated in a global phase III development program for Peyronie’s disease with top line data expected in the first half of 2012.

“Today, Asahi Kasei Pharma and Auxilium have forged a partnership, which we believe has the opportunity to offer the first, effective nonsurgical treatment for two diseases in Japan,” said ▇▇▇▇▇▇▇ ▇▇▇▇▇, Chief Executive Officer and President of Auxilium. “With the strength of Asahi Kasei Pharma’s development and commercialization organizations in Japan, we believe this relationship greatly enhances our ability to effectively introduce this potentially groundbreaking product.”

Asahi Kasei Pharma will pay Auxilium $15 million upfront. Under the terms of the agreement, Asahi Kasei Pharma will also make up to $247 million in potential milestone payments, with $37 million tied to development and regulatory milestones and $210 million based on sales milestones. Auxilium will receive increasing tiered double-digit royalties based on sales of XIAFLEX in Japan and will supply product to Asahi Kasei Pharma at a predetermined cost.

“Our partnership with Auxilium reinforces Asahi Kasei Pharma’s commitment to seek out innovative products that complement our existing portfolio in orthopedics and urology and address significant unmet medical needs in Japan,” said ▇▇▇▇▇▇ ▇▇▇▇▇, President and Representative Director of Asahi Kasei Pharma. “We look forward to combining our organizational strengths to develop the potential for XIAFLEX as a novel nonsurgical treatment for patients suffering from Dupuytren’s contracture and Peyronie’s disease in Japan.”

CONFIDENTIAL

EXECUTION VERSION

Auxilium will remain primarily responsible for the global development of XIAFLEX in Peyronie’s disease and will be responsible for all clinical and commercial drug manufacturing and supply. Asahi Kasei Pharma will be responsible for clinical development and regulatory activities and associated costs in Japan. Furthermore, Asahi Kasei Pharma will have a right of first negotiation to obtain exclusive rights to commercialize XIAFLEX pipeline indications in Japan.

About XIAFLEX

XIAFLEX (collagenase clostridium histolyticum) is a biologic approved in the U.S. and the EU for the treatment of adult Dupuytren’s contracture patients with a palpable cord. XIAFLEX is a novel nonsurgical treatment for this condition and consists of a highly purified combination of several subtypes of collagenase, derived from clostridium histolyticum, in specific proportion. It is also in phase III of a global development program for the treatment of Peyronie’s disease and is in phase II of development for the treatment of Frozen Shoulder syndrome (Adhesive Capsulitis). Together, they work synergistically to break the bonds of the triple helix collagen structure more effectively than human collagenase.

Claims for Auxilium’s U.S. Patent No. 7,811,560 include, among other things, purified collagenase, which is the active component in XIAFLEX (collagenase clostridium histolyticum). This patent entitled “COMPOSITIONS AND METHODS FOR TREATING COLLAGEN-MEDIATED DISEASES” is expected to expire in July 2028. The Company has filed continuation applications with the USPTO, which, if granted, may expand the scope of patent claims covering XIAFLEX. An international patent covering the same claims as the U.S. patent is currently under review outside of the U.S.

About Dupuytren’s Contracture

Dupuytren’s contracture is a condition that affects the connective tissue that lies beneath the skin in the palm. The disease is progressive in nature. Typically, nodules develop in the palm as collagen deposits accumulate. As the disease progresses, the collagen deposits form a cord that stretches from the palm of the hand to the base of the finger. Once this cord develops, the patient’s fingers contract and the function of the hand is impaired. The incidence of Dupuytren’s contracture is highest in Caucasians, historically those of Northern European descent, with a global prevalence of three to six percent of the Caucasian population. (1) The incidence of Dupuytren’s contracture in a Japanese population is estimated to be less than seen in Caucasian populations. Most cases of Dupuytren’s contracture occur in patients older than 50 years. (2)

The most frequently affected parts of the hand associated with Dupuytren’s contracture are the joints called the Metacarpal Phalangeal Joint, or MP joint, which is the joint closest to the palm of the hand and the Proximal Intra-Phalangeal Joint, or the PIP joint, which is the middle joint in the finger. The little finger and ring finger are most frequently involved. XIAFLEX is the only drug approved by the U.S. Food and Drug Administration for treatment of Dupuytren’s contracture, which has historically been treated primarily by an open surgical procedure.

About Peyronie’s Disease

Peyronie’s disease is the development of collagen plaque, or scar tissue, on the shaft of the penis that hardens and reduces flexibility, thus causing pain and forcing the penis to bend or arc during erection. This may prevent intercourse. In addition to difficulty with sexual intercourse, Peyronie’s disease may also be associated with emotional distress, bother, loss of self-esteem and depression.

About Xiaflex

Xiaflex (collagenase clostridium histolyticum), a biologic developed by Auxilium Pharmaceuticals, Inc., consists of a highly purified combination of several subtypes of collagenase derived from clostridium histolyticum in specific proportion. As a locally injectable treatment, it is the first effective non-surgical therapy for Dupuytren’s contracture, and has been approved in the US and the EU for this indication. Xiaflex is now also in Phase III of a global development program for the treatment of Peyronie’s disease, and in Phase II of development for the treatment of frozen shoulder syndrome (adhesive capsulitis).

About Dupuytren’s contracture

Dupuytren’s contracture is a condition that affects aponeurotic tissue (a kind of connective tissue) beneath the skin of the palm, causing a fixed flexion contracture of the fingers as the disease progresses. The incidence of Dupuytren’s contracture is highest in Caucasians of Northern European descent, but there remain many unknowns regarding its pathogenic mechanism. Xiaflex is the only drug which shows effectiveness for the treatment of Dupuytren’s contracture, which has conventionally been treated by surgery.

About Peyronie’s disease

Peyronie’s disease is the development of collagen plaque, or scar tissue, on the shaft of the penis that hardens and reduces flexibility, thus causing pain and forcing the penis to bend or arc during erection, possibly preventing intercourse. The disease occurs mostly in middle-aged men, and is possibly associated with other afflictions such as diabetes, erectile dysfunction (ED), and Dupuytren’s contracture. The precise number of patients is unknown.

About clostridium histolyticum

Clostridium histolyticum is a bacterium that secretes various kinds of collagenase-like proteinase which decompose tissue for it to feed on and multiply. As it exhibits a strong enzymatic activity, the collagenase derived from Clostridium histolyticum is often used in the separation of cells from animal tissue during the course of various biochemical and physiological research.

About collagenase

Collagenase is an enzyme which breaks apart collagen, a fibrous protein that plays a vital role in maintaining connective tissue and bones in animals.
