9.6 Bankruptcy Code. All rights and licenses granted under or pursuant to this Agreement are, and shall otherwise be deemed to be, for purposes of Section 365(n) of Title 11 of the United States Code and other similar laws in any jurisdiction outside the U.S. (collectively, the “Bankruptcy Laws”), licenses of rights to be “intellectual property” as defined under the Bankruptcy Laws. If a case is commenced during the Term by or against a party under Bankruptcy Laws then, unless and until this Agreement is rejected as provided in such Bankruptcy Laws, such party (in any capacity, including debtor-in-possession) and its successors and assigns (including a trustee) shall perform all of the obligations provided in this Agreement

to be performed by such party. If a case is commenced during the Term by or against a party under the Bankruptcy Laws, this Agreement is rejected as provided in the Bankruptcy Laws and the other party elects to retain its rights hereunder as provided in the Bankruptcy Laws, then the party subject to such case under the Bankruptcy Laws (in any capacity, including debtor-in-possession) and its successors and assigns (including a Title 11 trustee), shall provide to the other party copies of all Information necessary for such other party to prosecute, maintain and enjoy its rights under the terms of this Agreement promptly upon such other party’s written request therefor. All rights, powers and remedies of the non-bankrupt party as provided herein are in addition to and not in substitution for any and all other rights, powers and remedies now or hereafter existing at law or in equity (including, without limitation, the Bankruptcy Laws) in the event of the commencement of a case by or against a party under the Bankruptcy Laws.

9.7 Damages; Relief. Termination of this Agreement shall not preclude either party from claiming any other damages, compensation or relief that it may be entitled to hereunder.

10.

INDEMNIFICATION.

10.1 Indemnification by GBMT. GBMT hereby agrees to save, defend, indemnify and hold harmless Curis, its Affiliates and their respective officers, directors, employees, consultants and agents (the “Curis Indemnitees”) from and against any and all losses, damages, liabilities, expenses and costs, including reasonable legal expense and attorneys’ fees (“Losses”), to which any Curis Indemnitee may become subject as a result of any claim, demand, action or other proceeding by any Third Party to the extent such Losses arise directly or indirectly out of (a) the development, manufacture, use, handling, storage, sale, distribution or other disposition of any Compound or Product by or on behalf of GBMT or any of its Affiliates or Sublicensees, (b) the gross negligence or willful misconduct of any GBMT Indemnitee (defined below), or (c) the breach by GBMT of any warranty, representation, covenant or agreement made by it in this Agreement; except, in each case, to the extent such Losses result from the gross negligence or willful misconduct of any Curis Indemnitee or the breach by Curis of any warranty, representation, covenant or agreement made by it in this Agreement.

10.2 Indemnification by Curis. Curis hereby agrees to save, defend, indemnify and hold harmless GBMT, its Affiliates and their respective officers, directors, employees, consultants and agents (the “GBMT Indemnitees”) from and against any and all Losses to which any GBMT Indemnitee may become subject as a result of any claim, demand, action or other proceeding by any Third Party to the extent such Losses arise directly or indirectly out of (a) the gross negligence or willful misconduct of any Curis Indemnitee, or (b) the breach by Curis of any warranty, representation, covenant or agreement made by Curis in this Agreement; in each case, except to the extent such Losses result from the gross negligence or willful misconduct of any GBMT Indemnitee or the breach by GBMT of any warranty, representation, covenant or agreement made by GBMT in this Agreement.

10.3 Control of Defense. In the event a party seeks indemnification under Section 10.1 or 10.2, it shall inform the other party (the “Indemnifying Party”) of a claim as soon as reasonably practicable after such party (the “Indemnified Party”) receives notice of the claim (it being understood and agreed, however, that the failure by an Indemnified Party to give notice of a claim as provided in this Section 10.3 shall not relieve the Indemnifying Party of its

indemnification obligation under this Agreement except and only to the extent that such Indemnifying Party is actually damaged as a result of such failure to give notice), shall permit the Indemnifying Party to assume direction and control of the defense of the claim (including the right to settle the claim solely for monetary consideration), and shall cooperate as requested (at the expense of the Indemnifying Party) in the defense of the claim. The Indemnified Party shall not agree to any settlement of such action, suit, proceeding or claim without the prior written consent of the Indemnifying Party. The Indemnifying Party shall not agree to any settlement of such action, suit, proceeding or claim or consent to any judgment in respect thereof that does not include a complete and unconditional release of the Indemnified Party from all liability with respect thereto, that imposes any liability or obligation on the Indemnified Party or that acknowledges fault by the Indemnified Party; in each case, without the prior written consent of the Indemnified Party.

10.4 Insurance. GBMT, at its own expense, shall maintain product liability and other appropriate insurance in an amount consistent with industry standards during the Term. GBMT shall provide a certificate of insurance evidencing such coverage to Curis upon request.

11.

DISPUTE RESOLUTION.

11.1 Disputes. Subject to Section 11.4, upon the written request of either party to the other party, any claim, dispute, or controversy as to the breach, enforcement, interpretation or validity of this Agreement will be referred to the Chief Executive Officer of Curis and ▇▇. ▇▇▇▇, for resolution. In the event the two individuals referred to in the preceding sentence are unable to resolve such matter within 30 days after the initial written request, then, upon the written demand of either party, the matter shall be subject to arbitration, as provided in Section 11.2, except as expressly set forth in Section 11.4.

11.2 Arbitration.

(a) Subject to Section 11.4 below, any dispute, controversy or claim that is not resolved pursuant to Section 11.1 shall be resolved by final and binding arbitration in accordance with the applicable rules of the London Court of International Arbitration (“LCIA”) as then in effect (the “Rules”), except to the extent any such Rule conflicts with the express provisions of this Article 11.

(b) The arbitration shall be conducted by an arbitral tribunal of three neutral arbitrators selected by the LCIA Court in accordance with the Rules; provided that such arbitrators shall not be current or former employees or directors, or current stockholders, of either party, any of their respective Affiliates or any Sublicensee; and provided, further, that each arbitrators shall have experience and familiarity with commercial licensing practices in the pharmaceutical and biotechnology industries. The place of arbitration shall be Boston, Massachusetts, USA, and all proceedings and communications shall be in English.

(c) The arbitral tribunal shall permit discovery (including both the production of documents and deposition testimony) as reasonably necessary for an understanding of any legitimate issue raised in the arbitration, while also taking into account the desirability of making discovery efficient and cost-effective.

(d) The arbitral tribunal shall, in rendering an award, apply the substantive law of the Commonwealth of Massachusetts, USA, without giving effect to its principles of conflicts of law, and without giving effect to any of its rules or laws relating to arbitration. The award shall include a written statement describing the essential findings and conclusions upon which the award is based, including the calculation of any damages awarded. The arbitral tribunal’s authority to award special, incidental, consequential or punitive damages shall be subject to the limitation set forth in Section 7.5, except to the extent the substantive laws of the Commonwealth of Massachusetts, USA, do not permit such limitation. The award rendered by the arbitral tribunal shall be final, binding and non-appealable (subject only to the parties’ right to request correction of any errors in computation, clerical or typographical errors, or other errors of a similar nature, and the arbitral tribunal’s right to make any such correction on its own initiative, in each case, in accordance with the Rules), and judgment upon the award may be entered in any court of competent jurisdiction.

(e) 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 arbitration; provided, however, that the arbitral tribunal shall be authorized to determine whether a party is the prevailing party, and if so, to award to that prevailing party reimbursement for any or all of its reasonable attorneys’ fees, costs and disbursements (including, for example, expert witness fees and expenses, photocopy charges, travel expenses, etc.), and/or the fees and costs of the LCIA Court and the arbitral tribunal.

11.3 Confidentiality of Arbitration. Except to the extent necessary to confirm or enforce an award or as may be required by applicable law, neither a party nor the arbitral tribunal may disclose the existence, content, or results of an arbitration without the prior written consent of both parties.

11.4 Injunctive Relief; Court Actions. Either party may apply to the arbitrators for interim injunctive relief until the arbitration award is rendered or the controversy is otherwise resolved. Either party also may, without waiving any remedy under this Agreement, seek from any court having jurisdiction any injunctive or other equitable relief in the context of a bona fide emergency or prospective irreparable harm, and such an action may be filed and maintained notwithstanding any ongoing discussions between the parties or any ongoing arbitration proceeding. In addition, either party may bring an action in any court of competent jurisdiction to resolve disputes pertaining to the validity, construction, scope, enforceability, infringement or other violations of Patents or other intellectual property rights, and no such claim shall be subject to arbitration pursuant to Section 11.2. Further, no claim under any antitrust, anti-monopoly or competition law or regulation, whether or not statutory, shall be subject to arbitration pursuant to Section 11.2.

12.

MISCELLANEOUS.

12.1 No Implied Licenses. No right or license under any Information, Patents or other intellectual property rights of either party is granted or shall be granted by implication. All such rights or licenses are or shall be granted only as expressly provided in this Agreement.

12.2 Governing Law. This Agreement shall be governed by, and construed and enforced in accordance with, the laws of the Commonwealth of Massachusetts, USA, excluding its conflicts of laws principles.

12.3 Entire Agreement; Modification. This Agreement (including the Exhibits hereto) is both a final expression of the parties’ agreement and a complete and exclusive statement with respect to all of its terms. This Agreement supersedes all prior and contemporaneous agreements and communications, whether oral, written or otherwise, concerning any and all matters contained herein; provided, however, that this Agreement is not intended to supersede any written agreement in place between Curis and Changgeng Qian, M.D., Ph.D., including, without limitation, the CQ/Curis Agreement, each of which shall remain in full force and effect in accordance with its terms. This Agreement may only be modified or supplemented in a writing expressly stated for such purpose and signed by the parties to this Agreement.

12.4 Relationship between the Parties. The parties’ relationship, as established by this Agreement, is solely that of independent contractors. This Agreement does not create any partnership, joint venture or similar business relationship between the parties. Neither party is a legal representative of the other party and neither party can assume or create any obligation, representation, warranty or guarantee, express or implied, on behalf of the other party for any purpose whatsoever.

12.5 Non-Waiver. The failure of a party to insist upon strict performance of any provision of this Agreement or to exercise any right arising out of this Agreement shall neither impair that provision or right nor constitute a waiver of that provision or right, in whole or in part, in that instance or in any other instance. Any waiver by a party of a particular provision or right shall be in writing, shall be as to a particular matter and, if applicable, for a particular period of time and shall be signed by such party.

12.6 Assignment. Except as expressly provided hereunder, neither this Agreement nor any rights or obligations hereunder may be assigned or otherwise transferred by either party without the prior written consent of the other party (which consent shall not be unreasonably withheld); provided, however, that Curis may assign this Agreement and its rights and obligations hereunder without GBMT’s consent:

(a) in connection with the transfer or sale of all or substantially all of Curis’ business to which this Agreement relates to a Third Party, whether by merger, sale of stock, sale of assets or otherwise, provided that in the event of such a sale or transfer (whether this Agreement is actually assigned or is assumed by the acquiring party by operation of law (e.g., in the context of a reverse triangular merger)), intellectual property rights of the acquiring party in such sale or transfer (if other than Curis) shall not be included in the technology licensed hereunder or otherwise subject to this Agreement; or

(b) to an Affiliate of Curis, provided that Curis shall remain liable and responsible to GBMT for the performance and observance of all such duties and obligations by such Affiliate.

The rights and obligations of the parties under this Agreement shall be binding upon and inure to the benefit of the successors and permitted assigns of the parties, and the name of a party appearing herein will be deemed to include the name of such party’s successors and permitted assigns to the extent necessary to carry out the intent of this section. Any assignment not in accordance with this Agreement shall be void.

12.7 No Third Party Beneficiaries. This Agreement is neither expressly nor impliedly made for the benefit of any party other than those executing it.

12.8 Severability. If, for any reason, any part of this Agreement is adjudicated invalid, unenforceable or illegal by a court of competent jurisdiction, then such adjudication shall not, to the extent feasible, affect or impair, in whole or in part, the validity, enforceability or legality of any remaining portions of this Agreement. All remaining portions shall remain in full force and effect as if the original Agreement had been executed without the invalidated, unenforceable or illegal part.

12.9 Notices. Any notice to be given under this Agreement must be in writing and delivered either in person, by any method of mail (postage prepaid) requiring return receipt, or by overnight courier or facsimile confirmed thereafter by any of the foregoing, to the party to be notified at its address(es) given below, or at any address such party has previously designated by prior written notice to the other. Notice shall be deemed sufficiently given for all purposes upon the earliest of: (a) the date of actual receipt; (b) if mailed, five (5) days after the date of postmark; or (c) if delivered by overnight courier, the next business day the overnight courier regularly makes deliveries.
