(b) Initial Development Plan. Not later than the Effective Date, the Parties shall have agreed on the initial Development plan and related timelines for the Licensed Product in the Field in the Territory, which shall be incorporated as part of this Agreement as Schedule 3.2(b) (as may be amended and updated annually in accordance with this Agreement, the “Development Plan”). Schering shall have the right to review and comment on the clinical protocols for studies conducted in accordance with the Development Plan, including review of the design and endpoints of such studies so that such studies will lead to an outcome that is credible and reproducible, which comments Licensee shall consider and incorporate as Licensee deems appropriate in good faith. At Schering’s written request, the President of Schering’s research division, or his designee, and the President of Licensee’s research division or equivalent position, or his designee, shall meet to discuss such comments. Any revision of the clinical protocols shall be submitted to Schering promptly after their completion.

(c) Annual Development Plan. Not later than thirty (30) days after December 31 of each Calendar Year, Licensee shall submit to Schering an updated Development Plan for the pending Calendar Year. Such update shall take into account completion, commencement, changes in or cessation of Development activities not contemplated by the then-current Development Plan in sufficient detail to reflect the continued diligence of Licensee and shall reflect effort and resources consistent with other priority projects of Licensee. Schering shall have the right to comment on such annual plan. In the event Schering reasonably disagrees with the plan, Licensee shall consider Schering’s comments for revising the plan. At Schering’s written request, the President of Schering’s research division, or his designee, and the President of Licensee’s research division or equivalent position, or his designee, shall meet to discuss such comments. Any revision of the annual plan shall be submitted to Schering promptly after its completion.

(e) Performance. Licensee shall perform, and shall ensure that its Affiliates, sublicensees, and Third Party contractors perform, the activities described in the Development Plan in a professional manner and in compliance with, to the extent applicable, Good Laboratory Practices, Good Clinical Practices and/or Good Manufacturing Practices and in compliance with all other applicable laws, rules, and regulations.

(f) Program Know-How. Each Party shall share Program Know-How owned or Controlled by it with the other Party in a reasonably detailed annual report (“Know-How Report”). Such Know-How Reports will be exchanged by the Parties prior to January 31^st of each Calendar Year of the Term.

3.3 Development Reports. Licensee shall provide Schering with reasonably detailed reports describing its progress with respect to its Development efforts under this Agreement (hereinafter “Development Reports”). Such Development Reports shall be furnished annually until the First Commercial Sale. Each Development Report shall include the following information for the Licensed Product: a description of the Development work to be conducted during the year in reasonable detail, including, to the extent applicable, clinical studies, formulation work, Manufacturing work, other testing work and regulatory activity; timelines for such work; and key decision gates and milestones for such work.

3.4 Commercialization Reports. Commencing with the First Commercial Sale and thereafter on an annual basis, Licensee shall provide Schering with a written non-binding estimate of annual Net Sales for the Licensed Product in the Territory (“Annual Commercialization Report”). The Annual Commercialization Report shall also list all ongoing Commercialization Studies and the status of such studies in the United States, the Major European Countries and Japan.

3.5 Contract Sales Force. Notwithstanding anything to the contrary in this Agreement, Licensee shall not use the services of sales representatives employed by a Third Party as a contract sales force for Licensed Product without the prior written consent of Schering, such consent not to be unreasonably withheld.

3.6 Development and Commercialization Costs. Licensee shall be solely responsible for all costs related to the Development and/or Commercialization of the Licensed Product in the Field in the Territory following the Effective Date.

3.7 Commercialization of Licensed Product in the Field.

(a) Sales in the Field. Licensee hereby covenants that it shall not, nor shall it authorize any Affiliate, permitted sublicensee or Third Party contractor to Commercialize Licensed Product in the Territory for any use outside the Field. Schering hereby covenants that it shall not, nor shall it authorize any Affiliate, permitted sublicensee or Third Party contractor to Commercialize Licensed Product in the Territory for any use in the Field. Each Party acknowledges and understands that the other Party cannot control the ultimate use of the Licensed Products it sells and that the purpose of the foregoing covenant is to prevent such Party and its Affiliates and sublicensees from facilitating or encouraging uses in the other Party’s Field. To the extent either Party can prove the other Party materially breached this Section 3.7(a), such material breach shall permit such non-breaching Party to terminate this Agreement for cause under Section 12.4.

(b) Licensed Product Packaging. Each Party shall use reasonable efforts to ensure that Licensed Product it is Commercializing (in the Field with respect to Licensee and outside the Field with respect to Schering) is packaged and identified in a manner such that it is distinguishable from Licensed Product that the other Party is Commercializing in its respective Field, including not using trademarks, trade dress, product appearance, product packaging, and other such distinguishing characteristics that the other Party is using or is planning to use. The Parties shall cooperate in good faith to share information about each Party’s respective Licensed Product (which information shall constitute the Proprietary Information of the disclosing Party) in order to allow each Party to comply with its obligations under this Section 3.7(b).

Page 11 of 41

(c) Lost Sales. The Parties recognize that Schering has the right to Commercialize Licensed Products for indications outside the Field. As a result, the Parties acknowledge and desire to address the potential for Cross-Field Sales such that the Parties agree as follows:

(i) If at any time during the Term of this Agreement, Schering, its Affiliate, or licensees (other than Licensee) is Commercializing a product containing a Licensed Compound approved by the relevant Regulatory Authority for an indication outside the Field (a “Non-Licensee Field Product”) and Licensee is at the same time Commercializing a Licensed Product approved by the relevant Regulatory Authority for an indication in the Field (a “Licensee Field Product”), and a Party reasonably believes that (1) sales of a Non-Licensee Field Product are occurring or will occur for use in the approved indication in the Field; or (2) sales of the Licensee Field Product are occurring or will occur for use in the approved indication outside the Field, then such Party may provide notice to the other Party of its desire to track sales of Licensed Product for the relevant indications either in the Field or outside the Field, as applicable.

(ii) Upon receipt of notice under Section 3.7(c)(i), Schering and Licensee shall meet and agree upon a method of tracking sales of each possible Cross-Field Sale (a “Sales Tracking Methodology”) including (1) the acquisition of one or more prescription data products or services (including, by way of example, IMS Xponent, NDC, or DDD data, data from the UNOS database or other data from organizations tracking transplant surgeries or patients) or other relevant pharmaceutical sales tracking research services (including, for example, use of random sampling, use of data regarding distribution channels as a proxy for indication-specific sales or development of mathematical models for approximating indication-specific sales) generally recognized in the pharmaceutical industry as having a reasonably high degree of accuracy and reliability in the tracking of sales of pharmaceutical products that have a similar nature as and are prescribed by similar physicians as the applicable License Product (collectively, the “Data Services”), and (ii) the methodology for applying any such resulting data and information provided by such Data Services to determine the extent of Cross-Field Sales.

(iii) In the event that Schering and Licensee are unable to agree on a Sales Tracking Methodology pursuant to Section 3.7(c)(ii), then the following default methodologies shall apply:

(1) With respect to each of the U.S., the Major EU Countries and Japan (collectively, the “Major Regulatory Jurisdictions”), in which a Licensee Field Product and a Non-Licensee Field Product have received Regulatory Approval and in which Data Services are available at a reasonable cost (evaluated in light of the anticipated accuracy of such data and anticipated magnitude of Cross-Field Sales in such country), sales in the approved indications in the Field in such country and sales in the approved indications outside the Field in such country shall be calculated for each Licensee Field Product and each Non-Licensee Field Product based on the sales levels reported by the Data Services for such country.

(2) For all countries other than Major Regulatory Jurisdictions, the percentage of sales of each Licensee Field Product attributable to use in the approved indications outside the Field and the percentage of sales of each Non-Licensee Field Product attributable to use in the approved indications in the Field shall be calculated from total sales of such products based on the assumption that the ratio of Cross-Field Sales to total sales in such country is equal to the ratio of Cross-Field Sales to total sales calculated across all Major Regulatory Jurisdictions in which Cross-Field Sales are evaluated pursuant to Section 3.7(c)(iii)(1). In the event that there are no Major Regulatory Jurisdictions in which Cross-Field Sales are evaluated pursuant to Section 3.7(c)(iii)(1), then no Sales Tracking Methodology shall apply unless and until the Parties agree on a Sales Tracking Methodology pursuant to Section 3.7(c)(ii).

(3) All costs associated with the acquisition and application of such Data Services and Sales Tracking Methodology shall be shared equally by the Parties. In addition, the Parties shall also meet and confer with respect to: (A) how to account for prescriptions to patients with multiple afflictions that are both within and outside the Field (i.e., approved indications in the Field and approved indications outside of the Field); (B) the right for each Party to audit, on a periodic basis, the application of the Data Services and Sales Tracking Methodology; and (C) a mechanism for addressing prescriptions that are tracked back to sole source purchasing agreements.

Page 12 of 41

(iv) If in the course of applying the foregoing Data Services and methodologies to track sales of the Licensee Field Product and Non- Licensee Field Product pursuant to this Section 3.7, or in the course of performing an audit of such application by the other Party, a Party determines that Cross-Field Sales by the other Party are occurring at more than the greater of (A) [ * ] or (B) [ * ] of such Party’s total Net Sales of the Licensed Product, then the Parties shall compensate each other as follows:

(1) In the event that there are Cross-Field Sales by Licensee, Licensee shall make a payment to Schering equal to the amount of Licensee’s Cross-Field Net Sales less Licensee’s Cross-Field Sales Cost of Goods; and

(2) In the event that there are Cross-Field Sales of Schering, Schering shall make a payment to License equal to the amount of Schering’s Cross-Field Net Sales less Schering’s Cross-Field Cost of Goods.

(v) Both Parties acknowledge that in order to respect confidentiality, it may not be possible to share non-publicly available data with each other. Therefore, any discussion or dispute in relation to the compensation for Cross-Field Sales under Section 3.7(iv) will be submitted to an independent auditor acceptable to both Parties and that is subject to appropriate confidentiality obligations.

The Parties shall consult prior to initiating a recall or withdrawal of Licensed Product in the U.S., Japan, or a Major European Country; provided, however, that the final decision as to whether to recall or withdraw a Licensed Product in the Territory shall be made by (i) Licensee in the Field in its sole discretion, or (ii) Schering outside the Field in its sole discretion. A Party initiating a recall shall be responsible, at its sole expense, for conducting such recalls or taking such other necessary remedial action.

(g) Schering’s obligations to provide assistance and support under this Section 4.1 shall not extend beyond Licensee’s initial IND filing date with respect to the Licensed Product in the Field.

Schering grants to Licensee, the right to reference its Regulatory Application(s) or Regulatory Approval(s) covering the Licensed Product outside the Field in the Territory only to the extent required for Licensee to Develop, Manufacture and obtain and maintain Regulatory Approvals for the Licensed Product in the Field in the Territory; provided, however, that (a) such right of reference shall be used solely for purposes of this Agreement and (b) all information which is subject to the right of reference shall be treated by Licensee as Proprietary Information of Schering in accordance with Article 9. Except with the prior written consent of Licensee, which shall not be unreasonably withheld, conditioned or delayed, Schering shall not withdraw any Regulatory Application or Regulatory Approval that is subject to reference by Licensee hereunder.

4.3 Pharmacovigilance.

(a) After the Effective Date, Licensee shall be solely responsible for the collection, review, assessment, tracking and regulatory submission of safety-related information with respect to adverse events (“AEs”) associated with Licensed Product developed and commercialized by the Licensee in the Field, in accordance with 21 CFR 312.32, 314.80 and comparable applicable law governing AEs outside of the United States.

5.1 Generally. Licensee shall use Commercially Reasonable Efforts to Develop the Licensed Product in the Field in accordance with the Development Plan and to Commercialize the Licensed Product in the Field in the Territory. The activities of any Affiliate or sublicensee of Licensee will be treated as activities of Licensee in any determination whether Licensee has satisfied its obligation with respect to this Article V.

5.2 Failure. Any failure by Licensee to comply with the obligations set forth in this Article V shall be deemed to be a material breach for which Schering may exercise its termination rights under Section 12.4(b).

ARTICLE VI – MANUFACTURING

7.5 Maintenance of Records; Audits.

(a) Record Keeping by Licensee. Licensee and its Affiliates shall keep complete and accurate records in sufficient detail to enable the royalties payable hereunder to be determined. Upon [ * ] prior written notice from Schering, Licensee shall permit an independent certified public accounting firm of nationally recognized standing selected by Schering and reasonably acceptable to Licensee, at Schering’s expense, to have access during normal business hours to examine the pertinent books and records of Licensee as may be reasonably necessary to verify the accuracy of the royalty reports hereunder. The examination shall be limited to the pertinent books and records for any year ending not more than [ * ] prior to the date of such request. An examination under this Section 7.5(a) shall not occur more than [ * ] in any Calendar Year. Licensee may designate competitively sensitive information which such auditor may not disclose to Schering, provided, however, that such designation shall not encompass the auditor’s conclusions. The accounting firm shall disclose to Schering only whether the royalty reports are correct or incorrect and the specific details concerning any discrepancies. No other information shall be provided to Schering. All such accounting firms shall sign a confidentiality agreement (in form and substance reasonably acceptable to Licensee) as to any of Licensee’s or its Affiliate’s or sublicensee’s confidential information which such accounting firms are provided, or to which they have access, while conducting any audit pursuant to this Section 7.5(a).

(b) Underpayments/Overpayments. If such accounting firm correctly concludes that additional royalties were owed during such period, Licensee shall pay such additional royalties within [ * ] of the date Schering delivers to Licensee such accounting firm’s written report so correctly concluding. If such underpayment exceeds [ * ] of the sums correctly due Schering then the fees charged by such accounting firm for the work associated with the underpayment audit shall be paid by Licensee. Any overpayments by Licensee will be credited against future royalty obligations or refunded to Licensee within [ * ] following request by Licensee for the same, at Licensee’s option.

(c) Record Keeping by Sublicensees. Licensee shall include in each Sublicense Agreement entered into pursuant to this Agreement a provision requiring the sublicensee to make reports to Licensee and to keep and maintain records of sales made pursuant to such sublicense and provide copies of such records to Licensee upon reasonable request in order for Schering’s independent accountant to review such records to the same extent required of Licensee under this Agreement.

(d) Confidentiality. Schering shall treat all financial information subject to review under this Section 7.5, or under any Sublicense Agreement, in accordance with the confidentiality provisions of Article IX of this Agreement, and shall cause its accounting firm to enter into an acceptable confidentiality agreement with Licensee obligating it to retain all such financial information in confidence pursuant to such confidentiality agreement.

If Licensee elects to continue the prosecution or maintenance, Schering shall execute such documents and perform such acts, at Licensee’s expense, as may be reasonably necessary to effect an assignment of such Schering Prosecution Patents to Licensee. Any such assignment shall be completed in a timely manner to allow Licensee to continue such prosecution or maintenance. Any patents or patent applications so assigned shall no longer be considered Compound Patent Rights or Program Patents, as applicable.

In the event that either Licensee or Schering becomes aware of any alleged or threatened infringement in a country in the Field in the Territory of any issued patent within the Schering Prosecution Patents, it will notify the other Party in writing to that effect. [ * ] shall have three (3) months from the date of said notice to obtain a discontinuance of such infringement or bring suit against the Third Party infringer if such infringement relates to the use of the Licensed Product in the Field. If [ * ] fails to proceed within the specified 3-month period of time, then [ * ] shall have the right to obtain a discontinuance of such infringement or bring suit against the Third Party infringer only in the event that: (i) [ * ] a discontinuance of such infringement or [ * ] suit against the Third Party infringer [ * ] or (ii) [ * ] a discontinuance of such infringement or [ * ] suit against the Third Party infringer [ * ] and, in such discontinuance or suit, if [ * ], [ * ] discontinuance or suit. In the event that [ * ] is able to exercise its “step-in” rights to enforce Schering Prosecution Patents under this Section 8.5, [ * ] shall reimburse [ * ] costs and expenses for cooperation following the exercise of [ * ] step-in rights and all costs of enforcement going forward (provided, however, that if [ * ] later joins the enforcement action, then [ * ] shall be obligated for [ * ] costs and expenses after joining). The Party not initiating an action hereunder shall be notified prior to commencement of the trial, suit or action brought by the other Party and may join any such suit or action. In the event a Party joins an action hereunder, it shall pay one-half of the costs of such suit or action. In the event that a Party has joined in the action and shared in the costs thereof as set forth above, no settlement, consent judgment or other voluntary final disposition of the suit may be entered into without the consent of joining Party, which consent shall not be unreasonably withheld. In the event that a Party has not joined the suit or action, such Party will in any event reasonably cooperate with the acting Party in any such suit or action and shall have the right to consult with such acting Party and be represented by its own counsel at its own expense. Any recovery or damages derived from a suit which a Party has joined and shared costs shall be used first to reimburse each of the Parties for its documented out-of-pocket legal expenses relating to the suit, with any remaining amounts to be shared [ * ], and [ * ]. Any recovery or damages derived from a suit which a Party has not joined shall be [ * ]. Schering shall incur no liability to Licensee as a consequence of litigation or any unfavorable decision resulting therefrom, including any decision holding any of the Schering Prosecution Patents invalid or unenforceable. Licensee shall incur no liability to Schering as a consequence of litigation or any unfavorable decision resulting therefrom brought pursuant to this Section 8.5.

8.6 Infringement and Third Party Licenses.

(a) Course of Action. In the event that Licensee’s, its Affiliates’ or its sublicensees’ making, having made, importing, exporting, using, manufacturing, having manufactured Licensed Compound or Licensed Product or distributing, marketing, promoting, offering for sale or selling Licensed Product infringes, will infringe or is alleged by a Third Party to infringe, a claim of a patent that specifically covers the Licensed Compound, Licensed Product or its Manufacture, the Party becoming aware of same shall promptly notify the other. The Parties shall thereafter attempt to agree upon a course of action which may include: (i) modification of the Licensed Product or Licensed Compound or its use and Manufacture so as to be non-infringing; or (ii) obtaining a license or assignment from said Third Party.

(b) Licensee Right to Negotiate. In the event the Parties cannot agree on modifying the Licensed Product or Licensed Compound pursuant to Section 8.6(a), Licensee shall have the first right, but not the obligation, to negotiate with said Third Party for a suitable license or assignment. In the event that such negotiation results in a definitive agreement and the claimed infringement is for the making, using or selling of the Licensed Compound, then any lump sum or royalty payment made thereunder shall be paid by Licensee and Licensee shall have the right to offset such amount in accordance with Section 2.6. If Licensee fails to enter into a license or assignment pursuant to this Section 8.6(b), then following written notice from Licensee of such failure, Schering shall have the right to negotiate with said Third Party for a suitable license or assignment.

8.7 Third Party Infringement Suit. In the event that a Third Party sues Licensee alleging that Licensee’s, its Affiliates’ or its sublicensees’ making, having made, importing, exporting, using, manufacturing, having manufactured Licensed Compound or Licensed Product or distributing, marketing, promoting, offering for sale or selling Licensed Product infringes or will infringe a claim of a patent that specifically covers the Licensed Compound, Licensed Product or its manufacture, then Licensee may elect to defend such suit and, during the period in which such suit is pending, notwithstanding Licensee’s obligation to indemnify Schering under Section 11.1 herein, Licensee shall have the right to apply up to [ * ] of the royalties due Schering on sales of the allegedly infringing Licensed Product against its reasonable out-of-pocket litigation expenses.

Page 20 of 41

8.8 Abandonment. Schering shall promptly give notice to Licensee of the grant lapse, revocation, surrender, invalidation or abandonment of any Schering Prosecution Patents licensed to Licensee.

8.9 Patent Term Extension. The Party obtaining first Regulatory Approval for the Licensed Product in the United States shall be entitled to seek patent term extension in connection with the Compound Patent Rights. In the event that Licensee obtains such first Regulatory Approval, Schering agrees to cooperate with Licensee in the event that Licensee seeks patent term extension for the Compound Patent Rights; provided that Licensee reimburses all Schering’s costs and expenses in connection therewith, including Schering’s internal costs.

(a) Nondisclosure Obligation. Each of Schering and Licensee shall use any Proprietary Information received by it from the other Party only in accordance with this Agreement and shall not disclose, except as expressly provided herein, to any Third Party any such Proprietary Information without the prior written consent of the other Party. The foregoing obligations shall survive the expiration or termination of this Agreement for a period of [ * ]. These obligations shall not apply to Proprietary Information that:

(b) Permitted Disclosures.

(i) Notwithstanding anything to the contrary herein, the receiving Party may disclose the Proprietary Information of the disclosing Party solely to the extent such disclosure is required by applicable law, regulation, rule, act or order of any Governmental Authority or agency to be disclosed, provided that notice is promptly delivered to the disclosing Party in order to provide an opportunity to seek a protective order or other similar order with respect to such Proprietary Information and thereafter the receiving Party discloses to the requesting entity only the minimum information required to be disclosed in order to comply with the request, whether or not a protective order or other similar order is obtained by the disclosing Party.

(ii) Each of the Parties agrees not to disclose the terms and conditions of this Agreement to any Third Party and shall not make any public announcement or issue any press release in relation thereto, or otherwise publicize the existence or contents of this Agreement without the prior written approval by the other Party of the form, content and timing of such announcement, press release or other public disclosure.

determined by its legal counsel) to be disclosed in order to comply with the rules and regulations of the United States Securities and Exchange Commission (or another similar securities exchange authority in Territory); (ii) to existing or potential acquirers or merger candidates, potential sublicensees or collaborators (to the extent contemplated hereunder), or to Affiliates, each of whom prior to disclosure must be bound by obligations of confidentiality and non-use at least equivalent in scope to those set forth in this Article 9; (iii) to investment bankers, existing or potential investors, venture capital firms or other financial institutions or investors for purposes of obtaining financing, if such recipients are bound by obligations of confidentiality and non-use at least equivalent in scope to those set forth in this Article 9; or (iv) in response to a valid order of a court or other governmental body.

The receiving Party will return all documents, and copies thereof, including those in the possession of the receiving Party’s Agents pursuant to Section 9.1(b), containing the disclosing Party’s Proprietary Information at any time upon the written request of the disclosing Party. However, the receiving Party may retain one (1) copy of such documents in a secure location solely for the purposes of (a) determining its obligations hereunder, (b) complying with any applicable regulatory requirements, or (c) defending against any product liability claim.

9.3 Breach of Confidentiality. The Parties agree that the disclosure of the disclosing Party’s Proprietary Information in violation of this Agreement may cause the disclosing Party irreparable harm and that any breach or threatened breach of this Agreement by the receiving Party entitles disclosing Party to seek injunctive relief, in addition to any other legal or equitable remedies available to it, in any court of competent jurisdiction.

9.4 No Publicity. A Party may not use the name of the other Party in any publicity or advertising and may not issue a press release or otherwise publicize or disclose any information related to the existence of this Agreement or the terms or conditions herein, except (a) on the advice of its counsel as required by law (e.g., any Securities and Exchange Commission filings and disclosures) and provided the Party who will be disclosing such information has consulted with the other Party to the extent feasible prior to such disclosure with respect to the substance of the disclosure; or (b) as consented to in advance by the other Party in writing. The Parties shall agree on a form of initial press release that may be used by either Party on an ongoing basis to describe this Agreement. Each Party shall use good faith efforts to provide the other Party with reasonable advance written notice of any press release or other public disclosure of the results of any of its work on Licensed Products during the Term, provided that a Party’s failure to do so shall not constitute a material breach of this Agreement.

9.5 Publication. To the extent that any proposed publication or public presentation (including without limitation any abstracts or manuscripts for publication, slides and texts of oral or other public presentations, and texts of any transmission through any electronic media (e.g., any computer access system such as the Internet, World Wide Web etc.) collectively or individually a “Public Presentation”) to be made by a Party or its Affiliates may contain Proprietary Information of the other Party, the Party intending to make such publication or presentation shall provide to such other Party an advance copy of any such proposed publication or presentation prior to its submission or dissemination to any Third Party. The Party receiving such proposed publication or presentation shall have a period of at least [ * ] to review and recommend any changes it reasonably believes are necessary to protect its Proprietary Information. The Party intending to make such publication or presentation shall remove any Proprietary Information of the other Party therefrom; other changes recommended by such other Party shall not be unreasonably refused. In addition, if such publication could in the reviewing Party’s reasonable judgment be expected to have a material adverse effect on the commercial value of the reviewing Party’s Proprietary Information (or in the case of a proposed publication by Schering, on the Licensed Product in the Field), then the reviewing Party shall have the right to delay or prevent such publication as proposed by providing written notice to that effect during such [ * ] period. In the case where such publication may disclose any Program IP, any such delay shall be sufficiently long to permit the timely preparation and filing of a patent application(s) (or application(s) for other appropriate forms of protection) on the Proprietary Information involved.

ARTICLE XI - INDEMNIFICATION AND LIMITATION ON LIABILITY

11.1 Indemnification by Licensee. Licensee shall indemnify, defend and hold harmless Schering and its Affiliates, and each of its and their respective employees, officers, directors and agents (each, a “Schering Indemnified Party”) from and against any and all Third Party liability, loss, damage, cost, and expense (including reasonable attorneys’ fees), subject to the limitations in Section 11.5 (collectively, a “Liability”) which a Schering Indemnified Party may incur, suffer or be required to pay resulting from or arising out of (a) the Development, Manufacture, promotion, distribution, use, marketing, sale or other disposition of the Licensed Product in the Field by Licensee, its Affiliates or sublicensees, and (b) any material breach by Licensee of any of its representations, warranties and covenants contained in herein. Notwithstanding the foregoing, Licensee shall have no obligation under this Agreement to indemnify, defend or hold harmless any Schering Indemnified Party with respect to claims, demands, costs or judgments which result from the negligence or willful misconduct of Schering, its Affiliates, or any of their respective employees, officers, directors or agents, or Schering’s breach of its obligations under this Agreement.

11.2 Indemnification by Schering. Schering shall indemnify, defend and hold harmless Licensee and its Affiliates, and each of its and their respective employees, officers, directors and agents (each, a “Licensee Indemnified Party”) from and against any Third Party Liability which a Licensee Indemnified Party may incur, suffer or be required to pay resulting from or arising out of (i) the Development, Manufacture, promotion, distribution, use, marketing, sale or other disposition of the Licensed Product outside the Field by Schering, it Affiliates or sublicensees, and (ii) any material breach by Schering of any of its representations, warranties and covenants contained herein.

11.3 Conditions to Indemnification. The obligations of the indemnifying Party under Sections 11.1 and 11.2 are conditioned upon the delivery of written notice to the indemnifying Party of any potential Liability promptly after the indemnified Party becomes aware of such potential Liability. The indemnifying Party shall have the right to assume the defense of any suit or claim related to the Liability if it has assumed responsibility for the suit or claim in writing; however, if in the reasonable judgment of the indemnified Party, such suit or claim involves an issue or matter which could have a materially adverse effect on the business operations or assets of the indemnified Party, the indemnified Party may retain control of the defense or settlement thereof by providing written notice of such effect to the indemnifying Party, but in no event shall such action or notice be construed as a waiver of any indemnification rights that the indemnified Party may have at law or in equity. If the indemnifying Party defends the suit or claim, the indemnified Party may participate in (but not control) the defense thereof at its sole cost and expense. The foregoing notwithstanding, the Parties acknowledge and agree that failure of the indemnified Party to promptly notify the indemnifying Party of a potential Liability shall not constitute a waiver of, or result in the loss of, such Party’s right to indemnification under Section 11.1 or 11.2, as appropriate, except to the extent that the indemnifying Party’s rights, and/or its ability to defend against such Liability, are materially prejudiced by such failure to notify.

11.4 Settlements. Neither Party may settle a claim or action related to a Liability without the consent of the other Party, which consent shall not be unreasonably withheld, if such settlement would impose any monetary obligation on the other Party or require the other Party to submit to an injunction or otherwise limit the other Party’s rights under this Agreement. Any payment made by a Party to settle any such claim or action shall be at its own cost and expense.

11.5 Limitation of Liability. With respect to any claim by one Party against the other arising out of the performance or failure of performance of the other Party under this Agreement, the Parties expressly agree that the liability of such Party to the other Party for such breach shall be limited under this Agreement or otherwise at law or equity to direct damages only and in no event shall a Party be liable for punitive, exemplary or consequential damages, except to the extent the liability of such Party relates to its indemnification obligations of the other Party pursuant to this Article XI or a breach of the obligations of confidentiality and non-use set forth in Article IX.

This Agreement is effective on the earlier of: (i) the date after which the waiting period pursuant to the HSR Act has expired, (ii) the date on which the transaction contemplated in this Agreement has been approved by the FTC and DOJ, and (iii) if the Parties agree that no filing is required under the HSR Act, the date first written above (“Effective Date”).

12.2 Term and Expiration. This Agreement shall be effective as of the Effective Date and unless terminated earlier by mutual written agreement of the Parties or pursuant to Sections 12.3 or 12.4 below, the Term of this Agreement shall continue in effect on a country-by-country and product-by-product basis until the expiration of Licensee’s obligation to pay royalties under Article VII herein (the “Term”). Upon expiration of this Agreement in its entirety, Licensee’s license pursuant to Section 2.1 shall become a fully paid-up, non-exclusive, perpetual license.

12.3 Termination by Licensee.

(a) Licensee’s Right to Terminate. Notwithstanding anything contained herein to the contrary, Licensee shall have the unilateral right to terminate this Agreement in its entirety with or without cause, at any time by giving [ * ] advance written notice to Schering. In the event of such termination, the rights and obligations hereunder shall terminate; provided, however, that any payment obligations due and owing as of the termination date shall continue. For clarity, milestones achieved prior to the date of notice shall continue to be payable, but no additional milestone payments shall apply for activities conducted during the [ * ] notice period.

(b) Effect of Termination. Notwithstanding anything contained herein to the contrary, following any termination of this Agreement in its entirety under Section 12.3(a), all rights and licenses granted to Licensee hereunder shall revert back to Schering pursuant to Section 12.6.

12.4 Termination for Cause.

(a) Termination for Cause. This Agreement may be terminated, in its entirety by written notice by either Party at any time during the Term of this Agreement:

(i) if the other Party is in breach of its material obligations hereunder (except with respect to a breach by Licensee of its obligations under Section 5.2, for which termination pursuant to Section 12.4(b) shall be Schering’s sole and exclusive remedy) and has not cured such breach within [ * ] after receipt of written notice requesting cure of the breach, or in the event that the breach cannot be reasonably cured within such [ * ] period, has not initiated actions reasonably expected to cure such breach within [ * ] after receipt of such notice; or

Page 26 of 41

(ii) upon the filing or institution of bankruptcy, reorganization, liquidation or receivership proceedings by or against the other Party, or upon an assignment of a substantial portion of the assets for the benefit of creditors by the other Party, or in the event a receiver or custodian is appointed for such Party’s business, or if a substantial portion of such Party’s business is subject to attachment or similar process; provided, however, that in the case of any involuntary bankruptcy proceeding, such right to terminate shall only become effective if the proceeding is not dismissed within [ * ] after the filing thereof.

(b) Termination for Breach of Section 5.2. Subject to the terms and conditions of this Section 12.4(b), Schering shall have the right, and such right shall be its sole and exclusive remedy and Licensee’s sole and exclusive liability, to terminate this Agreement in the event Licensee and its Affiliates and sublicensees have ceased employing Commercially Reasonable Efforts to Develop and Commercialize Licensed Products in the Field for a period of [ * ] or more. In order to exercise such termination right, Schering shall first provide written notice to Licensee stating Schering’s reasons for concluding that Licensee and its Affiliates and sublicensees have ceased employing Commercially Reasonable Efforts to Develop and Commercialize Licensed Product in the Field for the aforementioned period. If Licensee disagrees with the conclusion that Licensee and its Affiliates and sublicensees have ceased employing Commercially Reasonable Efforts to Develop and Commercialize Licensed Product in the Field for the aforementioned period, Licensee shall have a period of [ * ] after such written notice to provide Schering with evidence that Licensee or any of its Affiliates or sublicensees has not ceased employing Commercially Reasonable Efforts to Develop and Commercialize Licensed Product in the Field for the aforementioned period. If Licensee has not provided Schering with such evidence within such [ * ] period, this Agreement shall terminate at the end of such [ * ] period upon written notice from Schering. Notwithstanding the foregoing, if Schering gives Licensee a notice pursuant to the second sentence of this Section 12.4(b), and Licensee provides notice during the [ * ] period set forth above that Licensee disputes the conclusion that Licensee and its Affiliates and sublicensees have ceased employing Commercially Reasonable Efforts to Develop and Commercialize Licensed Product in the Field for the aforementioned period, then this Agreement shall not terminate unless and until an arbitrator issues a final award pursuant to Article 13 upholding the basis for termination under this Section 12.4(b).

(i) Termination by Licensee for Cause. In the event this Agreement is properly terminated by Licensee under Section 12.4(a), Licensee’s license pursuant to Section 2.1 shall become a fully paid-up, perpetual license and the payments to be made to Schering by Licensee hereunder shall be reduced by [ * ]. Notwithstanding the preceding sentence, Licensee shall be responsible for the full amount of all payments due and owed to Schering prior to any written notice of termination.

(ii) Termination by Schering for Cause. In the event this Agreement is terminated by Schering under Section 12.4(a), the rights and license granted to Licensee under Section 2.1 of this Agreement shall terminate and all rights to the Licensed Compound and Licensed Product shall revert to Schering pursuant to Section 12.6.

12.5 Effect of Termination Generally. Expiration or termination of this Agreement shall not relieve the Parties of any obligation accruing prior to such expiration or termination, and the provisions of Sections 10.6, 10.7, 12.3(b), 12.4(c), 12.5 and 12.6 and Articles IX, XIII and XIV shall survive the expiration or termination of this Agreement. Any expiration or early termination of this Agreement shall be without prejudice to the rights of either Party against the other that has accrued and is owed under this Agreement prior to termination, including the obligation to pay royalties for Licensed Product sold prior to such termination.

12.6 Licensed Product Reversion. Upon termination of this Agreement in its entirety by Schering for any reason or by Licensee pursuant to Section 12.3, the following provisions shall apply:

Page 27 of 41

(b) Licensee shall reasonably cooperate with Schering in order to enable Schering to assume responsibility for the Development, Manufacture and/or Commercialization of all Licensed Products then being Developed, Manufactured or Commercialized by Licensee. Such cooperation and assistance shall be provided in a timely manner and shall include without limitation:

(i) Licensee shall transfer to Schering (or its nominee) all INDs, Regulatory Approvals, drug approval applications for Regulatory Approvals, and all supporting documentation for such filings and applications (to the extent assignable and not cancelled), made or obtained by Licensee or its Affiliates or any of its sublicensees to the extent relating to Licensed Product then being Commercialized or in Development.

(ii) Licensee shall assign to Schering all of its rights in any trademarks and shall transfer to Schering all of its rights in any domain names containing trademarks, in each case to the extent owned or Controlled by Licensee and to the extent that such trademarks have actually been or are planned to be utilized by Licensee in connection with the Commercialization of Licensed Product in the Field. Any assignment or transfer to Schering pursuant to this Section 12.6(b)(ii) shall be at no cost to Schering.

(iii) Licensee shall transfer to Schering (or its nominee), to the extent not previously provided, a copy of all Know-How owned or Controlled by Licensee relating to any Licensed Product then being Commercialized in the Field or in clinical Development by Licensee in the Field and reasonably necessary or useful for its continued Development, Manufacture and/or Commercialization in the Field, including without limitation all information contained in Licensee’s regulatory and/or safety databases, all in the format then currently maintained by Licensee.

(iv) Upon the request of Schering, Licensee shall use reasonable and Commercially Reasonable Efforts to assign to Schering any Sublicense Agreements previously granted by Licensee related to the Development of Licensed Product in the Field.

(v) Upon the request of Schering, Licensee, its Affiliates and its sublicensees shall complete any clinical studies related to Licensed Product in the Field that (x) are being conducted under Licensee’s IND for Licensed Product and are ongoing as of the date this Agreement is terminated, and (y) for which it is not practicable to transfer responsibility for conducting such studies to Schering; provided, however, that Schering agrees to reimburse Licensee for all Development costs incurred by Licensee after termination in completing such studies.

(vi) Upon the request of Schering, Licensee shall transfer to Schering, at a price to be agreed in good faith, which shall not be more than [ * ] of Licensee’s fully allocated manufacturing cost for the Licensed Product, all quantities of Licensed Product in the possession of Licensee or its Affiliates (including, without limitation, clinical trial supplies and Licensed Product intended for commercial sale).

(vii) At Schering’s request, Licensee shall promptly provide to Schering copies of all clinical trial, contract manufacturing, or service agreements entered into by Licensee or its Affiliates with respect to the Development or Manufacture of Licensed Product in the Field. At Schering’s request, Licensee shall promptly assign (or cause to be assigned), such agreements to Schering, to the extent such assignment is permitted under such agreement or, in the case that such agreements involve products other than the Licensed Product, to the extent that the portion of the agreement involving solely the Development or Manufacture of Licensed Product in the Field can be assigned. In the event that such an assignment is not permitted under a particular clinical trial, contract manufacturing, or service agreement, then Licensee shall reasonably cooperate (at Schering’s request) to assist Schering in obtaining the benefits of such agreement.

The Parties shall use commercially reasonable efforts to complete the transition of the Development, Manufacture and Commercialization of the Licensed Product from Licensee to Schering pursuant to this Section 12.6 as soon as is reasonably possible.

ARTICLE XIII – DISPUTE RESOLUTION

13.1 Informal Discussions. Except as otherwise provided herein, in the event of any controversy or claim arising out of or relating to this Agreement, or the rights or obligations of the Parties hereunder, or the relationship between the Parties with respect to the Licensed Compound or Licensed Product, the Parties shall first try to settle their differences amicably between themselves. Either Party may initiate such informal dispute resolution by sending written notice of the dispute to the other Party, and within [ * ] after such notice appropriate representatives of the Parties shall meet for attempted resolution by good faith negotiations. If such representatives are unable to resolve promptly such disputed matter within the said [ * ], either Party may refer the matter by written notice to the other to the Chief Executive Officer of Schering, or his designee, and the Chief Executive Officer of Licensee, or his designee, for discussion and resolution. If such individuals or their designees are unable to resolve such dispute within [ * ] of such written notice, either Party may initiate arbitration proceedings in accordance with the provisions of this Article XIII.

3.2 Arbitration. All disputes arising out of or relating to this Agreement, or the rights or obligations of the Parties hereunder, or relating in any way to the relationship between the Parties with respect to the Licensed Compound or Licensed Product, other than disputes relating to patent rights which shall be submitted to a court of competent jurisdiction (unless mutually agreed by the Parties), shall be finally and exclusively settled by arbitration by a panel of three (3) arbitrators.

(a) The arbitration proceeding shall be conducted under the Commercial Arbitration Rules of the American Arbitration Association (“AAA”) with such proceedings to be held in Newark, New Jersey, United States should a dispute be brought to arbitration by Licensee or in San Francisco, California should a dispute be brought to arbitration by Schering. In all cases, the arbitration proceedings shall be conducted in the English language, and all documents that are submitted in the proceeding shall be in the English language. Judgment upon the award rendered by arbitration may be issued and enforced by any court having competent jurisdiction.

(b) If a Party intends to begin an arbitration to resolve a dispute, such Party shall provide written notice to the other Party, informing the other Party of such intention and any statement of claim required under the applicable arbitration rules (as determined in accordance with Section 13.2(a)). Within [ * ] after its receipt of such notice, the other Party shall, by written notice to the Party initiating arbitration, add any additional issues to be resolved which would be considered mandatory counterclaims under New York law. For clarity, the resolution of any disputes regarding such counterclaims shall be conducted in the same proceedings as the initial claims.

(c) Within [ * ] following the receipt of the notice of arbitration, the Party referring the matter to arbitration shall appoint an arbitrator and promptly notify the other Party of such appointment. The other Party shall, upon receiving such notice, appoint a second arbitrator within [ * ], and the two (2) arbitrators shall, within [ * ] of the appointment of the second arbitrator, agree on the appointment of a third arbitrator who will act with them and be the chairperson of the arbitration panel. In the event that either Party shall fail to appoint an arbitrator within [ * ] after the commencement of the arbitration proceeding, the arbitrator shall be appointed by the AAA. In the event of the failure of the two (2) arbitrators to agree within [ * ] after the commencement of the arbitration proceeding to appoint the chairperson, the chairperson shall also be appointed by the AAA.

(i) All of the arbitrators shall have significant legal or business experience in pharmaceutical licensing matters. The arbitrators shall not be employees, directors or shareholders of either Party or any of their Affiliates.

(ii) Each Party shall have the right to be represented by counsel throughout the arbitration proceedings.

(iii) To the extent possible, the arbitration hearings and award will be maintained in confidence.

(iv) In any arbitration pursuant to this Agreement, the award or decision shall be rendered by a majority of the members of the panel provided for herein, with each member having one (1) vote. The arbitrators shall render a written decision with their resolution of the dispute, which decision shall set forth in reasonable detail the facts of the dispute, and the reasons for their decision. The decision of the arbitrators shall be final and non-appealable and binding on the Parties.

Page 29 of 41

13.3 Injunctive Relief. By agreeing to arbitration, the Parties do not intend to deprive any competent court of such court’s jurisdiction to issue a pre-arbitral injunction, pre-arbitral attachment or other order in aid of the arbitration proceedings and the enforcement of any award or judgment. Without prejudice to such provisional remedies in aid of arbitration as may be available under the jurisdiction of a national court, the court of arbitration shall have full authority to grant provisional remedies and to award damages for failure of any Party to respect the court of arbitration’s order to that effect.

13.4 Expenses of Arbitration and Expert Determination. Each Party shall bear its own attorneys’ fees, costs, and disbursements arising out of the arbitration, and shall pay an equal share of the fees and costs of the arbitrators; provided, however, that the arbitrators shall be authorized to determine whether a Party is the prevailing Party, and if so, to award to that prevailing Party reimbursement for its reasonable attorneys’ fees, costs and disbursements (including, for example, expert witness fees and expenses, photocopy charges and travel expenses). Absent the filing of an application to correct or vacate the arbitration award as permitted by applicable law, each Party shall fully perform and satisfy the arbitration award within [ * ] of the service of the award.

ARTICLE XIV - MISCELLANEOUS

14.1 Assignment/Change of Control.

(a) Assignment. Neither this Agreement nor any or all of the rights and obligations of a Party hereunder may be assigned, delegated, sold, transferred, sublicensed (except as otherwise provided herein) or otherwise disposed of, by operation of law or otherwise, to any Third Party without the prior written consent of the other Party, and any attempted assignment, delegation, sale, transfer, prohibited sublicense or other disposition, by operation of law or otherwise, of this Agreement or of any rights or obligations hereunder contrary to this Section 14.1 shall be a material breach of this Agreement by the attempting Party, and shall be void and without force or effect; provided, however, that either Party may, without such consent of such Party, assign the Agreement and its rights and obligations hereunder to an Affiliate or in connection with the transfer or sale of all or substantially all of its assets related to the division or the subject business, or in the event of its merger or consolidation or change in control or similar transaction. This Agreement shall be binding upon, and inure to the benefit of, each Party, its Affiliates, and its permitted successors and assigns. Each Party shall be responsible for the compliance by its Affiliates with the terms and conditions of this Agreement.

(b) Change of Control of Licensee. In the event that any Change of Control (as defined below) causes Licensee’s rights and obligations hereunder to pass to any Third Party, such Third Party shall, within [ * ] after the effective date of such Change of Control, notify Schering of its intentions with regard to the Development and Commercialization of the Licensed Product under this Agreement. If the Third Party succeeding to Licensee’s rights and obligations under this Agreement decides it will not continue the Development and/or Commercialization of the Licensed Product, then Schering shall have the right to terminate this Agreement upon [ * ] written notice to Licensee without any opportunity to cure and the effects of such termination shall be as set forth in Section 12.6. If the Third Party succeeding to Licensee’s rights and obligations under this Agreement decides to continue the Development and Commercialization of the Licensed Product, then all of the rights and obligations of Licensee under this Agreement shall inure to such Third Party; provided, that for the immediate [ * ] period following such Change of Control, such Third Party shall follow the same Development Plan and budget as was in effect prior to such Change of Control; and provided, further that within such [ * ] period the Third Party successor shall submit to Schering a new Development Plan for the next succeeding [ * ] period, which shall not, without the prior written approval of Schering, which approval shall not be unreasonably withheld, materially differ from the Development Plan in effect prior to such Change of Control.

(c) Definition of Change of Control. As used in this Section 14.1 the term “Change of Control” means (i) any merger, reorganization, consolidation or combination in which Licensee is not the surviving corporation, or (ii) any “person” (within the meaning of Sections 13(d) and 14 (d)(2) of the Securities Exchange Act of 1934), excluding Licensee and its Affiliates, is or becomes the beneficial owner, directly or indirectly, of securities of Licensee representing 50% or more of either (A) the then-outstanding shares of common stock of Licensee or its parent

Page 30 of 41

corporation, or (B) the combined voting power of Licensee’s then-outstanding voting securities; or (C) if individuals who as of the Effective Date constitute the Board of Directors of Licensee or its parent corporation (the “Incumbent Board”) cease for any reason to constitute at least a majority of such Board of Directors; provided, however, that any individual becoming a director subsequent to the Effective Date whose election, or nomination for election by Licensee’s stockholders, was approved by a vote of at least a majority of the directors then comprising the Incumbent Board shall be considered as though such individual were a member of the Incumbent Board, but excluding, for this purpose, any such individual whose initial assumption of office occurs as a result of an actual or threatened election contest with respect to the election or removal of directors or other actual or threatened solicitation of proxies or consents by or on behalf of a person other than the Incumbent Board; or (D) approval by the stockholders of Licensee of a complete liquidation or the complete dissolution of Licensee.

14.2 Governing Law. This Agreement shall be governed, interpreted and construed in accordance with the laws of the State of New York, without giving effect to its conflict of law principles. Subject to the terms of this Agreement, all disputes under this Agreement shall be governed by binding arbitration pursuant to the mechanism set forth in Article XIII herein.

14.3 Waiver. Any delay or failure in enforcing a Party’s rights under this Agreement or any waiver as to a particular default or other matter shall not constitute a waiver of such Party’s rights to the future enforcement of its rights under this Agreement, nor operate to bar the exercise or enforcement thereof at any time or times thereafter, excepting only as to an express written and signed waiver as to a particular matter for a particular period of time.

14.4 Independent Relationship. Nothing herein contained shall be deemed to create an employment, agency, joint venture or partnership relationship between the Parties hereto or any of their agents or employees, or any other legal arrangement that would impose liability upon one Party for the act or failure to act of the other Party. Neither Party shall have any power to enter into any contracts or commitments or to incur any liabilities in the name of, or on behalf of, the other Party, or to bind the other Party in any respect whatsoever.

14.5 Export Control. This Agreement is made subject to any restrictions concerning the export of products or technical information from the United States of America which may be imposed upon or related to Schering or Licensee from time to time by the government of the United States of America. Furthermore, Licensee agrees that it will not export, directly or indirectly, any technical information acquired from Schering under this Agreement or any products using such technical information to any country for which the United States government or any agency thereof at the time of export requires an export license or other governmental approval, without first obtaining the written consent to do so from the Department of Commerce or other agency of the United States government when required by an applicable statute or regulation.

14.6 Entire Agreement; Amendment. This Agreement, including the Exhibits and Schedules hereto and thereto, sets forth the complete, final and exclusive agreement and all the covenants, promises, agreements, warranties, representations, conditions and understandings between the Parties hereto and supersedes and terminates all prior agreements and understandings between the Parties with regard to the subject matter of this Agreement in the Territory. There are no covenants, promises, agreements, warranties, representations, conditions or understandings, either oral or written, between the Parties other than as are set forth herein and therein. No subsequent alteration, amendment, change, waiver or addition to this Agreement shall be binding upon the Parties unless reduced to writing and signed by an authorized officer of each Party. As of the Effective Date, this Agreement supersedes and terminates that certain Secrecy Agreement between the Parties effective as of November 20, 2008.
