In the event that *** fails to initiate or defend such action within *** after being first notified of such infringement or misappropriation, *** shall have the right, but not the obligation, to do so at its sole expense (subject to Section 10.1.5). Similarly, *** shall have the first right to initiate legal action to enforce all Joint Patents against infringement and to protect all Jointly Owned Inventions from misappropriation, by any Third Party where such infringement or misappropriation ***, or to defend any declaratory judgment action relating thereto, at its sole expense (subject to Section 10.1.5). In the event that *** fails to initiate or defend such action within *** after being first notified of such infringement, *** shall have the right, but not the obligation, to do so at its sole expense (subject to Section 10.1.5). *** shall *** coordinate legal action to enforce all Joint Patents against infringement, and to protect all Jointly Owned Inventions from misappropriation, by any Third Party where such infringement or misappropriation ***, or to defend any declaratory judgment action relating thereto, and *** the costs and expenses of such litigation ***.

10.1.5 If one Party exercises its right to initiate or defend legal action against a Third Party as set forth in Section 10.1.4 above, the other Party agrees to be joined as a party plaintiff where necessary and to give the initiating/defending Party reasonable assistance and authority to file and prosecute the suit. In such case, the costs and expenses of the non-initiating/non-defending shall be borne by that Party, but all other costs and expenses of the litigation shall be borne by the initiating/defending Party. Any damages or other monetary awards recovered shall be *** in *** to the ***. A settlement or consent judgment or other voluntary final disposition of a suit under this Section 10.1.5 may not be entered into without the consent of the Party not bringing the suit.

10.2 Inventions Owned by Syndax.

14.2.2 Indemnification by Merck. Merck agrees to defend, indemnify and hold harmless Syndax, its Affiliates, and its and their employees, directors, subcontractors and agents from and against any Liability to the extent that such Liability ***.

14.2.3 Procedure. The obligations of Merck and Syndax under this Section 14.2 are conditioned upon the delivery of written notice to Merck or Syndax, as the case might be, of any potential Liability within a reasonable time after a Party becomes aware of such potential Liability. A Party will have the right to assume the

defense of any suit or claim related to the Liability (using counsel reasonably satisfactory to the other Party) if it has assumed responsibility for the suit or claim in writing. The other Party may participate in (but not control) the defense thereof at its sole cost and expense. The Party controlling such defense (the “Defending Party”) shall keep the other Party (the “Other Party”) advised of the status of such action, suit, proceeding or claim and the defense thereof and shall consider recommendations made by the Other Party with respect thereto. The Defending Party shall not agree to any settlement of such action, suit, proceeding or claim without the prior written consent of the Other Party, which shall not be unreasonably withheld. The Defending 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 Other Party from all liability with respect thereto or that imposes any liability or obligation on the Other Party without the prior written consent of the Other Party.

14.2.4 Study Subjects. Syndax shall not offer compensation on behalf of Merck to any Study subject or bind Merck to any indemnification obligations in favor of any Study subject. Likewise, Merck shall not offer compensation on behalf of Syndax to any Study subject or bind Syndax to any indemnification obligations in favor of any Study subject.

14.3 LIMITATION OF LIABILITY. OTHER THAN WITH RESPECT TO DAMAGES ARISING OUT OF OR RELATED TO A PARTY’S BREACH OF ITS OBLIGATIONS UNDER THIS AGREEMENT TO USE, DISCLOSE, LICENSE, ASSIGN OR OTHERWISE TRANSFER SAMPLE TESTING RESULTS, CLINICAL DATA, CONFIDENTIAL INFORMATION AND JOINTLY-OWNED INVENTIONS ONLY AS PERMITTED HEREIN, IN NO EVENT SHALL EITHER PARTY (OR ANY OF ITS AFFILIATES OR SUBCONTRACTORS) BE LIABLE TO THE OTHER PARTY FOR, NOR SHALL ANY INDEMNIFIED PARTY HAVE THE RIGHT TO RECOVER, ANY SPECIAL, INDIRECT, INCIDENTAL, PUNITIVE OR CONSEQUENTIAL DAMAGES (INCLUDING LOST PROFITS OR DAMAGES FOR LOST OPPORTUNITIES), WHETHER IN CONTRACT, WARRANTY, NEGLIGENCE, TORT, STRICT LIABILITY OR OTHERWISE, ARISING OUT OF (x) THE MANUFACTURE OR USE OF ANY COMPOUND SUPPLIED HEREUNDER OR (y) ANY BREACH OF OR FAILURE TO PERFORM ANY OF THE PROVISIONS OF THIS AGREEMENT OR ANY REPRESENTATION, WARRANTY OR COVENANT CONTAINED IN OR MADE PURSUANT TO THIS AGREEMENT, EXCEPT THAT SUCH LIMITATION SHALL NOT APPLY TO DAMAGES PAID OR PAYABLE TO A THIRD PARTY BY AN INDEMNIFIED PARTY FOR WHICH THE INDEMNIFIED PARTY IS ENTITLED TO INDEMNIFICATION HEREUNDER.

15.	Use of Name.

Except as expressly provided herein, neither Party shall have any right, express or implied, to use in any manner the name or other designation of the other Party or any other trade name, trademark or logo of the other Party for any purpose in connection with the performance of this Agreement.

16.	Force Majeure.

If in the performance of this Agreement, one of the Parties is prevented, hindered or delayed by reason of any cause beyond such Party’s reasonable control (e.g., war, riots, fire, strike, governmental laws), such Party shall be excused from performance to the extent that it is necessarily prevented, hindered or delayed (“Force Majeure”). The non-performing Party will notify the other Party of such Force Majeure within *** after such occurrence by giving written notice to the other Party stating the nature of the event, its anticipated duration, and any action being taken to avoid or minimize its effect. The suspension of performance will be of no greater scope and no longer duration than is necessary and the non-performing Party will use commercially reasonable efforts to remedy its inability to perform.

17.	Entire Agreement; Modification.

The Parties agree to the full and complete performance of the mutual covenants contained in this Agreement. This Agreement, together with the Related Agreements, constitutes the sole, full and complete agreement by and between the Parties with respect to the subject matter of this Agreement, and all prior agreements, understandings, promises and representations, whether written or oral, with respect thereto are superseded by this Agreement. No amendments, changes, additions, deletions or modifications to or of this Agreement shall be valid unless reduced to writing and signed by the Parties hereto.

18.	Assignment and Sub-Contracting.

Neither Party shall assign or transfer this Agreement without the prior written consent of the other Party; provided, however, that no such consent shall be required in connection with a Change of Control of a Party. Notwithstanding the foregoing, either Party may, without consent of the other Party, assign all or any part of this Agreement to one or more of its Affiliates, and any and all rights and obligations of either Party may be exercised or performed by its Affiliates. In the event of a Change of Control of a Party, such Party undergoing the Change of Control shall notify the other Party in writing at least *** prior to completion of such Change of Control (to the extent such notification is legally permissible prior to completion of such Change of Control, and if such notification is not legally permissible prior to such Change of Control, then such notification shall be provided to the other Party in writing simultaneously with the first

public announcement with respect to such Change of Control). Any permitted assignee of a Party (which assignee shall include the Third Party in a Change of Control situation under Section 1.8(b)) shall, in writing to the non-assigning Party, expressly assume the obligation to perform this Agreement. Any attempted assignment not in accordance with this Section 18 shall be null and void and of no legal effect. The terms and conditions of this Agreement shall be binding upon, and shall inure to the benefit of, the Parties and their respected successors and permitted assigns.

19.	Invalid Provision.

If any provision of this Agreement is held to be illegal, invalid or unenforceable, the remaining provisions shall remain in full force and effect and will not be affected by the illegal, invalid or unenforceable provision. In lieu of the illegal, invalid or unenforceable provision, the Parties shall negotiate in good faith to agree upon a reasonable provision that is legal, valid and enforceable to carry out as nearly as practicable the original intention of the entire Agreement.

20.	No Additional Obligations.

Syndax and Merck have no obligation to renew this Agreement or apply this Agreement to any clinical trial other than the Study. Neither Party is under any obligation to enter into another type of agreement at this time or in the future.

21.	Dispute Resolution and Jurisdiction.

21.1 The Parties shall attempt in good faith to settle all disputes arising out of or in connection with this Agreement in an amicable manner. Any claim, dispute or controversy arising out of or relating to this Agreement, including the breach, termination or validity hereof or thereof (each, a “Dispute”), shall be governed by and construed in accordance with the substantive laws of the State of New York, without giving effect to its choice of law principles.

21.2 Nothing contained in this Agreement shall deny either Party the right to seek injunctive or other equitable relief from a court of competent jurisdiction in the context of a bona fide emergency or prospective irreparable harm, and such an action may be filed or maintained notwithstanding any ongoing discussions between the Parties.

22.
