labeling of Finished Product, then Indevus shall submit to Schering all information required therefore including, but not limited to art work and lay out, specifications for modified packaging, labels and labeling, pharmacological information, usage
instructions and warnings to be applied which, for Finished Product, shall be consistent with the FDA approved labeling, reasonably in advance of the delivery date where the changes shall first be implemented. Schering shall review such proposal in
due course (but no more than one (1) month) and, in the event of doubt, discuss with Indevus its possible effect(s) on Scherings manufacturing system including, if such changes are beyond Scherings capabilities taking into account
the technical requirements, the impact on costs and timelines and the possible impact on the price of the Finished Product.

11.4
Regulatory Filings of Changes. If a change relates to the DMF(s) Schering will determine the requirements of the FDA for such a change following consultation with Indevus. Schering will submit such change to the DMF(s). Schering will provide
to Indevus a revised authorization letter when a change is made to the DMF(s) and Indevus will submit it to the FDA along with any other necessary regulatory filings. Besides with respect to the DMF(s) Indevus shall be responsible for any other
filings required by the FDA, and Schering will reasonably assist Indevus to meet the respective governmental and/or regulatory requirements which, in Indevus judgment, must be fulfilled before implementation of the respective change.

other Documentation required under the Quality Assurance Agreement) prior to each shipment of Clinical Supplies and/or Finished Product and, unless otherwise agreed to by the Parties, will not ship Clinical Supplies or Finished Product until at
least ten (10) Business Days after Indevus receives such Documentation.

12.2Notice of Failure to Meet Specifications. In the
event Schering discovers that any Batch or lot of Finished Product fails to conform to the Specifications or applicable Regulatory Standards, Schering will notify Indevus within two (2) Business Days, if such Batch or lot has been shipped to
Indevus, of such failure to meet the Specifications or applicable Regulatory Standards, and of the nature thereof in detail, and will supply to Indevus such information related thereto as Indevus may reasonably request, including the results of all
inside and outside laboratory testing and conclusions, if any. At its expense, Schering shall investigate all such failures promptly, and cooperate with Indevus in determining the cause for the failure and a corrective action to prevent future
failures. In case a Batch or lot of Substance or Finished Product fails to conform to the Specifications or applicable Regulatory Standards which has not been included in Finished Product shipped to Indevus but where it reasonably could be expected
to possibly have a negative impact on Indevus supply of Finished Product, the matter will be discussed in the Supply Team.

12.3 Non-Compliance. Within thirty (30) Business Days following the receipt by Indevus or
Indevus designee at the final distribution point in the Territory of the later of (a) a shipment of Clinical Supplies or Finished Product; or (b) the related Documentation, Indevus and/ or its designees shall have the opportunity to
inspect (or to have inspected) such shipment for transport damages, shortage and, as far as reasonably practicable, any other defects and to perform quality control and acceptance testing, as required under the Quality Assurance Agreement, in order
to determine whether such Clinical Supplies or Finished Product conforms to the Specifications. Indevus shall notify Schering of any such damages, shortage and other reasonably discernible defects discovered by Indevus promptly following
Indevus discovery thereof, but in any event within such thirty (30) Business Day period.

12.4 Procedure as to Non-Compliant
Goods.

12.4.1 Non-Compliant Clinical Supplies or Finished Product. Unless otherwise requested by Schering
pursuant to the following sentence, Indevus shall return non-compliant Clinical Supplies or Finished Product to Schering. Schering may decide, however, to have an agent inspect such goods for non-compliance while in the possession of Indevus;
Indevus shall then be responsible for storing the non-compliant Clinical Supplies or Finished Product appropriately for a reasonable period of time, not to exceed thirty (30) days. If returned to Schering, the inspection shall be made on return
to Schering. If Schering accepts the Clinical Supplies or Finished Product as being non-compliant and the Clinical Supplies or Finished Product has not yet been returned to Schering, Schering shall decide whether such non-compliant Clinical Supplies
or Finished Product shall be returned to Schering or destroyed, subject to applicable laws and regulations; the costs of such storage, return or destruction shall be borne by Schering. At Indevus option and request, Schering will
(i) supply replacement Finished Product together with the relevant batch record and certificate of analysis to Indevus at no additional charge within two (2) months of notification of non-compliance pursuant to Section 12.3 above;
(ii) refund the Initial Payment applicable to the non-compliant Finished Product to Indevus, or (iii) credit Indevus account in an amount equal to the Initial Payment for the non-compliant Finished Product.

12.4.2 Non-Compliant Documents. Schering shall immediately upon receipt of Indevus notification of non-compliance pursuant
to Section 12.3, inspect the relevant Documentation for non-compliance. If Schering accepts such Documentation as being non-compliant, Schering shall attempt to remedy the defect by providing to Indevus compliant Documentation as soon as
reasonably practical. If the defect can only be cured by sending new Clinical Supplies or Finished Product together with the relevant new batch record, certificate of analysis, and certificate of compliance, Schering will use Commercially Reasonable
Efforts to supply such replacement products to Indevus at no additional charge within two (2) months of Indevus notification of non-compliance pursuant to Section 12.3.

---

12.4.3 Disputes. If there is a dispute as to whether any portion of any shipment
of Clinical Supplies or Finished Product or a batch record or certificate of analysis is not in compliance, the Parties will attempt to reach a mutually acceptable resolution of the dispute. If they are unable to do so after a reasonable period of
time (such period not to exceed thirty (30) days from the date of original notification), such dispute shall be resolved by having an independent, mutually acceptable, qualified third party examining the respective Clinical Supplies or Finished
Product or batch record or certificate of analysis which shall be chosen by the Supply Team or the Steering Committee. If this third party finds the Clinical Supplies or Finished Product or batch record or certificate of analysis as being
non-compliant, Section 12.4.1 Sentences 4 and 5 and Section 12.4.2 Sentences 2 and 3 shall apply. Any out-of-pocket costs relating to the third party examination shall be borne by the Party which claimed compliance or non-compliance
incorrectly.

13.4 Disclaimer. EXCEPT AS SET FORTH ABOVE, SCHERING MAKES NO OTHER WARRANTY OR REPRESENTATION,
EXPRESS OR IMPLIED, CONCERNING ITS PERFORMANCE HEREUNDER, INCLUDING ANY WARRANTY OR MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE WITH RESPECT TO CLINICAL SUPPLIES OR FINISHED PRODUCT.

Article 14

Indemnification

14.1 Schering. Schering shall indemnify, defend and hold harmless Indevus and its directors, officers, employees, agents, successors and assigns
(each a Indevus Indemnitee) from and against any and all liabilities, damages, losses, costs or expenses (including reasonable attorneys' and professional fees and other expenses of litigation and/or arbitration) (a
Liability) resulting from a claim, suit or proceeding, including a product liability claim (Claim), made or brought by a Third Party against an Indevus Indemnitee arising out of, attributable to, or based on any claims
alleging (i) any breach by Schering of the representations and warranties set forth in Section 13.1 or 13.2 except to the extent caused by the negligence or willful misconduct of Indevus; or (ii) the negligence or willful misconduct
by Schering or any designee of Schering in exercising or performing any of Scherings rights or obligations under this Agreement.

14.2
Indevus. Indevus shall indemnify, defend and hold harmless Schering and its directors, officers, employees, agents, successors and assigns (each a Schering Indemnitee) from and against any and all liabilities, damages, losses,
costs or expenses (including reasonable attorneys' and professional fees and. other expenses of litigation and/or arbitration) (a Liability) resulting from a claim, suit or proceeding including a product liability claim (a
Claim), made or brought by a Third Party against a Schering Indemnitee, arising out of, attributable to, or based on any claims alleging (i) any breach by Indevus of the representations and warranties set forth in Section 13.1,
or (ii) any development, testing, importation, use, marketing, promotion, offer for sale, sale or other distribution of any Product by Indevus or its Affiliates and Sublicensee; except in each case to the extent caused by the negligence or
willful misconduct of Schering.

14.3 Procedure. In the event that any Indemnitee intends to claim indemnification under this Article
14 it shall promptly notify the other Party (the Indemnitor) in writing of such alleged Liability. Failure to provide prompt notice shall not relieve any Party of the duty to defend or indemnify unless such failure materially prejudices
the defense of any matter. The Indemnitor shall have the sole right to control the defense and settlement thereof provided, however, that an Indemnitor shall not, without the written consent of the other Party, as part of any settlement or
compromise (i) admit to liability on the part of the other Party; (ii) agree to an injunction against the other Party; or (iii) settle any matter in a manner that separately apportions fault to the other Party. The Parties further
agree that as part of the settlement of any indemnified Claim, unless otherwise agreed by the Indemnitees, an Indemnifying Party shall use Commercially Reasonable Efforts to obtain a full,



- 28 -



---

complete and unconditional release from the claimant on behalf of the Indemnitees. The Indemnitee shall
cooperate with the Indemnitor and its legal representatives in the investigation of any action, claim or liability covered by this Article 14, the Indemnitee shall have a reasonable opportunity to participate in decision-making with respect to the
strategy of such defense, and the Parties shall reasonably cooperate with each other in connection with the implementation thereof. The Indemnitee shall not, except at its own cost, voluntarily make any payment or incur any expense with respect to
any Claim without the prior written consent of the Indemnitor, which the Indemnitor shall not be required to give. Actions taken by the Indemnitor hereunder shall be without prejudice to the Indemnitors right to contest the Indemnitees
right to indemnification and subject to refund in the event the Indemnitor is ultimately held not to be obligated to indemnify the Indemnitee.

14.4 Survival. This Article 14 shall survive expiry or termination of this Agreement for any reason.

Article 15

Confidentiality

15.1 Confidential Information. Except to the extent expressly authorized by this Agreement or otherwise agreed in writing, the Parties agree that the receiving Party shall keep confidential and shall not publish or otherwise disclose
to any Third Party or use for any purpose other than as provided for in this Agreement any Know-how and other information and materials furnished to it by the other Party pursuant to this Agreement, or any provisions of this Agreement that are the
subject of an effective order of the SEC granting confidential treatment (collectively Confidential Information), except to the extent that it can be established by the receiving Party that such Confidential Information:

15.1.1 is or becomes public or available to the general public otherwise than through the act or default of the receiving Party;

15.1.2 is obtained by the receiving Party from a Third Party who is lawfully in possession of such Confidential
Information and is not subject to an obligation of confidentiality or non-use owed to the disclosing Party or others;

15.1.3 is previously known to the receiving Party prior to disclosure to the receiving Party by the disclosing Party under this Agreement, as shown by written evidence, and is not obtained or derived directly or indirectly from the
disclosing Party;

15.1.4 is disclosed by the receiving Party pursuant to the requirement of law, provided that the
receiving Party has complied with the provisions set forth in Section 15.3; or

15.1.5 is independently developed by
the receiving Party without the use of or reliance on any Confidential Information provided by the disclosing Party hereunder, as shown by contemporaneous written evidence.



- 29 -



---

15.2 Public Domain. For the purposes of this Agreement, specific information disclosed as part of
the Confidential Information shall not be deemed to be in the public domain or in the prior possession of the receiving Party merely because it is embraced by more general information in the public domain or by more general information in the prior
possession of the receiving Party.

15.3 Legal Disclosure. If the receiving Party becomes legally required to disclose any
Confidential Information provided by the disclosing Party, the receiving Party will give the disclosing Party prompt notice of such fact so that the disclosing Party may seek to obtain a protective order or other appropriate remedy concerning such
disclosure and/or waive compliance with the non-disclosure provision of this Agreement. The receiving Party will reasonably cooperate with the disclosing Party in connection with the disclosing Partys efforts to obtain any such order or other
remedy. If any such order or other remedy does not fully preclude disclosure or the disclosing Party waives such compliance, the receiving Party will make such disclosure only to the extent that such disclosure is legally required and will use its
reasonable efforts to have confidential treatment accorded to the disclosed Confidential Information.

15.4 Permitted Use and
Disclosures. Each Party hereto may use or disclose Confidential Information disclosed to it by the other Party to the extent such use or disclosure is reasonably necessary in complying with applicable governmental regulations or otherwise
submitting information to Regulatory Authorities, tax or other governmental authorities, conducting Pre-clinical Development or Clinical Development, or otherwise exercising its rights hereunder. If a Party is required to make any such disclosure of
another Party's Confidential Information, other than pursuant to a confidentiality agreement, it will give reasonable advance notice to the latter Party of such disclosure and, save to the extent inappropriate in the case of patent applications,
will use its reasonable efforts to secure confidential treatment of such Confidential Information prior to its disclosure (whether through protective orders or otherwise).

15.5 Public Disclosure. Except as otherwise required by law or set forth herein, neither Party shall issue a press release or make any other public disclosure of the terms of this Agreement without the prior
approval of such press release or public disclosure. Each Party shall submit any such press release or public disclosure to the other Party to review and approve any such press release or public disclosure, which approval shall not be unreasonably
withheld or delayed. If the receiving Party does not respond within forty-eight (48) hours from submission, the press release or public disclosure shall be deemed approved. In addition, if a public disclosure is required by law, including
without limitation in a filing with the SEC, the disclosing Party shall provide copies of the disclosure forty-eight (48) hours prior to such filing or other disclosure for the non-disclosing Party's prior review and comment, provided, however
that such right of review and comment shall only apply for



- 30 -



---

the first time that specific information is to be disclosed, and shall not apply to the subsequent
disclosure of substantially similar information that has previously been disclosed unless there have been material developments relating to Product since the date of the previous disclosure.

15.6 Confidential Terms. Except as expressly provided herein, each Party agrees not to disclose any terms of this Agreement to any Third Party
without the consent of the other Party which consent shall not be unreasonably withheld or delayed; except that disclosures may be made as required by securities or other applicable laws, or to actual or prospective investors or corporate partners,
or to a Party's accountants, attorneys and other professional advisors and that Indevus may file this Agreement as an exhibit to any filing with the SEC and may distribute any such filing in the ordinary course of its business, provided, however,
that to the maximum extent allowable by SEC rules and regulations, the Parties shall be obligated to maintain the confidentiality obligations set forth herein.

15.7 Publications. Each Party acknowledges the other Party's interest in publishing its results related to Product to obtain recognition within the scientific community and to advance the state of scientific
knowledge. Each Party also recognizes the mutual interest in obtaining valid patent protection and in protecting business interests and trade secret information. Accordingly, neither Party shall submit for written or oral publication any manuscript,
abstract or the like relating to Product without the prior approval of the other Party. Any Party proposing to submit such publication shall deliver the proposed publication or an outline of the oral disclosure at least thirty (30) Business
Days prior to planned submission or presentation (three (3) Business Days review in the case of meeting abstracts or similar presentations which do not contain Confidential Information of Schering). At the reasonable request of the other Party,
the submission of such publication may be delayed such that any issues of patent protection may be addressed. In the absence of any such request, upon expiration of the applicable period referred to in this Section 15.7 the publishing Party
shall be free to proceed with the publication or presentation. If the other Party requests modifications to the publication, the publishing Party shall edit such publication to prevent disclosure of trade secret or proprietary business information
prior to submission of the publication or presentation. The contribution of each Party, if any, shall be noted in all publications or presentations by acknowledgment or co-authorship, whichever is appropriate.

the expiry of the [*] as defined in the License Agreement.

|[*] | CONFIDENTIAL TREATMENT REQUESTED
|--- | --------------------------------

16.2 Termination for Cause. Failure of Indevus or Schering to comply with any of the respective
material obligations and conditions contained in this Agreement shall entitle the other Party to give the Party in default notice requiring it to cure such default. If such default is not cured within ninety (90) days after receipt of such
notice, the notifying Party shall be entitled (without prejudice to any of its other rights conferred on it by the Agreement) to terminate this Agreement by giving a notice to take effect immediately. Notwithstanding the foregoing, in the event of a
non-monetary default, if the default is not reasonably capable of being cured within the ninety (90) day cure period by the defaulting Party and such defaulting Party is making a good faith effort to cure such default, the notifying Party may
not terminate this Agreement, provided however, that the notifying Party may terminate this Agreement if such default is not cured within one hundred and eighty (180) days of such original notice of default. The right of either Party to
terminate this Agreement as herein above provided shall not be affected in any way by its waiver of, or failure to take action with respect to, any previous default.

16.3 Termination for Change of Control. Schering shall be entitled to terminate the Agreement upon written notice to Indevus within ninety (90) days after a Change of Control of Indevus if a direct
competitor with respect to Product in the Field in the Territory acquires control over Indevus.

16.4 Termination for Insolvency. If
voluntary or involuntary proceedings by or against a Party are instituted in bankruptcy or under any insolvency law, or a receiver or custodian is appointed for such Party, or proceedings are instituted by or against such Party for corporate
reorganization or the dissolution of such Party, which proceedings, if involuntary, shall not have been dismissed within sixty (60) days after the date of filing, or if such Party makes an assignment for the benefit of creditors, or
substantially all of the assets of such Party are seized or attached and not released within sixty (60) days thereafter, the other Party may immediately terminate this Agreement effective upon notice of such termination.

16.5 Indevus Rights Not Affected. All rights and licenses granted pursuant to this Agreement are, and shall otherwise be deemed to be, for purposes
of Section 365(n) of the Bankruptcy Code licenses of rights to intellectual property as defined under Section 101(35A) of the Bankruptcy Code. The Parties agree that each Party shall retain and may fully exercise all of their
respective rights, remedies and elections under the Bankruptcy Code. The Parties further agree that, in the event of the commencement of a bankruptcy or reorganization case by or against a Party under the Bankruptcy Code, the other Party shall be
entitled to all applicable rights under Section 365 (including 365(n)) of the Bankruptcy Code. Upon rejection of this Agreement by a Party or a trustee in bankruptcy for such Party, pursuant to Section 365(n), the other Party may elect
(i) to treat this Agreement as terminated by such rejection or (ii) to retain its rights (including any right to enforce any exclusivity provision of this Agreement) to intellectual property (including any embodiment of such intellectual
property) under this Agreement and under any agreement supplementary to this Agreement for the duration of this Agreement and any period for which this Agreement could have been



- 32 -



---

extended by such other Party. Upon written request to the trustee in bankruptcy or bankrupt Party, the
trustee or Party, as applicable, shall (i) provide to the other Party any intellectual property (including such embodiment) held by the trustee or the bankrupt Party and shall provide to the other Party a complete duplicate of (or complete
access to, as appropriate) any such intellectual property and all embodiments of such intellectual property and (ii) not interfere with the rights of the other Party to such intellectual property as provided in this Agreement or any agreement
supplementary to this Agreement, including any right to obtain such intellectual property (or such embodiment or duplicates thereof) from a Third Party.

16.6 Effect of Termination and Expiration.

16.6.1 Accrued Rights and
Obligations. Termination of this Agreement for any reason shall not release any Party hereto from any liability which, at the time of such termination, has already accrued to the other Party or which is attributable to a period prior to such
termination nor preclude either Party from pursuing any rights and remedies it may have hereunder or at law or in equity with respect to any breach of this Agreement. It is understood and agreed that monetary damages may not be a sufficient remedy
for any breach of this Agreement and that the non-breaching Party may be entitled to injunctive relief as a remedy for any such breach.

16.6.2 Survival. The rights and obligations set forth in this Agreement shall extend beyond the term or termination of this Agreement only to the extent expressly provided for herein, or to the extent that the
survival of such rights or obligations are necessary to permit their complete fulfillment or discharge.

17.5 Force Majeure. Neither Party shall lose any rights hereunder or be liable to the other
Party for damages or losses (except for payment obligations) on account of failure of performance by the defaulting Party if the failure is occasioned by war, strike, fire, Act of God, terrorism, earthquake, flood, lockout, embargo, governmental
acts or orders or restrictions or delays or failures to act, failure of suppliers, or any other reason where failure to perform is beyond the reasonable control and not caused by the negligence, intentional conduct or misconduct of the
non-performing Party and the non-performing Party has exerted Commercially Reasonable Efforts to overcome such force majeure; provided, however, that in no event shall a Party be required to settle any labor dispute or disturbance.

17.6 Severability. In the event that any provisions of this Agreement are determined to be invalid or unenforceable, the remainder of the Agreement
shall remain in full force and effect without said provision unless the absence of the invalidated provision(s) adversely affects the substantive rights of the Parties. In such event the Parties shall, in good faith, negotiate a substitute valid
provision for any provision declared invalid or unenforceable, which shall most nearly approximate the economic effect and intent of the invalid provision that it can be reasonably assumed that the Parties would have entered into this Agreement with
the substituted provision. The same shall apply in case of an omission.

17.11 Dispute
Resolution.

17.11.1 The Parties agree to attempt initially to solve all claims, disputes, or controversies arising
under, out of, or in connection with this Agreement (a Dispute) by conducting good faith negotiations. Any Disputes which cannot be resolved by good faith negotiation within sixty (60) days, shall be referred, by written notice from
either Party to the other, to the Chief Executive Officer of Indevus and the Head of the Global Business Unit Gynecology & Andrology of Schering. Such persons shall negotiate in good faith to achieve a resolution of the Dispute referred to
them within thirty (30) days after such notice is received by the Party to whom the notice was sent. If such persons are unable to settle the Dispute between them within thirty (30) days, they shall so report to the Parties in writing. The
Dispute shall then be referred to mediation as set forth in the following subsection 17.11.2.

17.11.2 Upon the Parties
receiving the report of the persons referred to in subsection 17.11.1 that the Dispute referred to them pursuant to subsection 17.11.1 (a) has not been resolved, the Dispute may be referred to mediation by written notice from either Party to
the other. The mediation shall be conducted pursuant to the mediation rules of the American Arbitration Association (AAA). In the event Indevus is the claimant, the mediation shall be held in London, England; in the event Schering is the
claimant, the mediation shall be held in New, York, New York, US. If the Parties have not reached a settlement within sixty (60) days of the date of the notice of mediation, the Dispute may be referred to arbitration pursuant to subsection
17.11.3.

17.11.3 If, after the procedures set forth in subsections 17.11.1 and 17.11.2, the
Dispute has not been resolved, and if a Party decides to institute arbitration proceedings, it shall give written notice to that effect to the other Party. The Parties shall refrain from instituting the arbitration proceedings for a period of sixty
(60) days following such notice. During such period, the Parties shall continue to make good faith efforts to amicably resolve the dispute without arbitration. If the Parties have not reached a settlement during that period the arbitration
proceedings shall go forward and be conducted in accordance with the then applicable commercial arbitration rules of the AAA except where modified herein. Each such arbitration shall be conducted by a panel of three arbitrators with appropriate
experience in the biotechnology or pharmaceutical industry: one arbitrator shall be appointed by each of Schering and Indevus and the third arbitrator, who shall be the Chairman of the tribunal, shall be appointed by the two Party-appointed
arbitrators. In the event Indevus is the claimant, the arbitration shall be held in London, England; in the event Schering is the claimant, the arbitration shall be held in New York, New York, US. The arbitrators shall have the authority to grant
specific performance. Any award so rendered shall be final and binding and judgment upon the award so rendered may be entered in any court having jurisdiction or application may be made to such court for judicial acceptance of any award and an order
of enforcement, as the case may be. In no event shall a demand for arbitration be made after the date when institution of a legal or equitable proceeding based on such claim, dispute or other matter in question would be barred by the applicable
statute of limitations. Each Party shall bear its own costs and expenses incurred in connection with any arbitration proceeding and the Parties shall equally share the costs of the mediation and arbitration levied by the AAA. Any mediation or
arbitration proceeding entered into pursuant to this Section 17.11 shall be conducted in the English language.

17.12 Headings.
The captions to the several Sections and Articles hereof are not a part of this Agreement, but are included merely for convenience of reference only and shall not affect its meaning or interpretation.

17.13 Counterparts. This Agreement may be executed in two counterparts, each of which shall be deemed an original and which together shall
constitute one instrument.

IN WITNESS WHEREOF Schering and Indevus have executed this Agreement by their respective duly authorized
representatives.
