Except as expressly stated in this Agreement, all warranties and conditions whether express or implied by statute, common law or otherwise (including any implied warranties of satisfactory quality or fitness for purpose) are excluded to the extent permitted by applicable Law.

13.1 Indemnification by Kaken. Kaken hereby agrees to save, indemnify, defend and hold Brickell, its Affiliates, and their respective directors, officers, agents and employees harmless from and against any and all losses, damages, liabilities, costs and expenses (including reasonable attorneys’ fees and expenses) (collectively, “Losses”) arising in connection with any and all charges, complaints, actions, suits, proceedings, hearings, investigations, claims, demands, judgments, orders, decrees, stipulations or injunctions by a Third Party (each a “Third Party Claim”) resulting or otherwise arising from (i) any breach by Kaken of any of its representations, warranties, covenants or obligations pursuant to this Agreement or (ii) the negligence or willful misconduct by Kaken or its Affiliates or their respective officers, directors, employees, agents, consultants or sublicensee in performing any obligations under this Agreement or (iii) any amounts payable to the Third Party Contract Manufacturer under any indemnification provisions in the Kaken Contract Manufacturer Supply Agreements on account of the acts of omissions of Kaken; in each case except to the extent that such Losses are subject to indemnification by Brickell pursuant to Section 13.2.

13.2 Indemnification by Brickell. Brickell hereby agrees to save, indemnify, defend and hold Kaken, its Affiliates, and their respective directors, agents and employees harmless

from and against any and all Losses arising in connection with any and all Third Party Claims resulting or otherwise arising from (i) any breach by Brickell of any of its representations, warranties, covenants or obligations pursuant to this Agreement or (ii) the negligence or willful misconduct by Brickell or its Affiliates or their respective officers, directors, employees, agents, consultants or sublicensees in performing any obligations under this Agreement; in each case except to the extent that such Losses are subject to indemnification by Kaken pursuant to Section 13.1.

(a) Notice of Claim. All indemnification claims in respect of any indemnitee seeking indemnity under Section 13.1 or 13.2, as applicable (collectively, the “Indemnitees” and each an “Indemnitee”) will be made solely by the corresponding Party (the “Indemnified Party”). The Indemnified Party will give the indemnifying Party (the “Indemnifying Party”) prompt written notice (an “Indemnification Claim Notice”) of any Losses and any legal proceeding initiated by a Third Party against the Indemnified Party as to which the Indemnified Party intends to make a request for indemnification under Section 13.1 or 13.2, as applicable, but in no event will the Indemnifying Party be liable for any Losses that result from any delay in providing such notice which materially prejudices the defense of such proceeding. Each Indemnification Claim Notice shall contain a description of the claim and the nature and amount of such Loss (to the extent that the nature and amount of such Loss are known at such time). Together with the Indemnification Claim Notice, the Indemnified Party will furnish promptly to the Indemnifying Party copies of all notices and documents (including court papers) received by any Indemnitee in connection with the Third Party Claim.

(b) Control of Defense. At its option, the Indemnifying Party may assume the defense of any Third Party Claim subject to indemnification as provided for in Section 13.1 or 13.2, as applicable, by giving written notice to the Indemnified Party within thirty (30) days after the Indemnifying Party’s receipt of an Indemnification Claim Notice. Upon assuming the defense of a Third Party Claim, the Indemnifying Party may appoint as lead counsel in the defense of the Third Party Claim any legal counsel it selects, and such Indemnifying Party shall thereafter continue to defend such Third Party Claim in good faith. Should the Indemnifying Party assume the defense of a Third Party Claim (and continue to defend such Third Party Claim in good faith), the Indemnifying Party will not be liable to the Indemnified Party or any other Indemnitee for any legal expenses subsequently incurred by such Indemnified Party or other Indemnitee in connection with the analysis, defense or settlement of the Third Party Claim, unless the Indemnifying Party has failed to assume the defense and employ counsel in accordance with this Section 13.3.

(c) Right to Participate in Defense. Without limiting Section 13.3(b), any Indemnitee will be entitled to participate in the defense of a Third Party Claim for which it has sought indemnification hereunder and to employ counsel of its choice

for such purpose; provided, however, that such employment will be at the Indemnitee’s own expense unless (i) the employment thereof has been specifically authorized by the Indemnifying Party in writing, or (ii) the Indemnifying Party has failed to assume the defense (or continue to defend such Third Party Claim in good faith) and employ counsel in accordance with this Section 13.3, in which case the Indemnified Party will be allowed to control the defense.

(d) Settlement. With respect to any Losses relating solely to the payment of money damages in connection with a Third Party Claim and that will not result in the Indemnitee becoming subject to injunctive relief and as to which the Indemnifying Party will have acknowledged in writing the obligation to indemnify the Indemnitee hereunder, the Indemnifying Party will have the sole right to consent to the entry of any judgment, enter into any settlement or otherwise dispose of such Loss, on such terms as the Indemnifying Party, in its reasonable discretion, will deem appropriate (provided, however, that such terms shall include a complete and unconditional release of the Indemnified Party from all liability with respect thereto), and will transfer to the Indemnified Party all amounts which said Indemnified Party will be liable to pay prior to the time of the entry of judgment. With respect to all other Losses in connection with Third Party Claims, where the Indemnifying Party has assumed the defense of the Third Party Claim in accordance with Section 13.3(b), the Indemnifying Party will have authority to consent to the entry of any judgment, enter into any settlement or otherwise dispose of such Loss, provided it obtains the prior written consent of the Indemnified Party (which consent will be at the Indemnified Party’s reasonable discretion). The Indemnifying Party that has assumed the defense of (and continues to defend) the Third Party Claim in accordance with Section 13.3(b) will not be liable for any settlement or other disposition of a Loss by an Indemnitee that is reached without the written consent of such Indemnifying Party. Regardless of whether the Indemnifying Party chooses to defend or prosecute any Third Party Claim, no Indemnitee will admit any liability with respect to, or settle, compromise or discharge, any Third Party Claim without first offering to the Indemnifying Party the opportunity to assume the defense of the Third Party Claim in accordance with Section 13.3(b).

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

Indemnified Party for all its reasonable out-of-pocket expenses incurred in connection with such cooperation.

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

13.4 Limitation of Liability. NEITHER PARTY SHALL BE LIABLE TO THE OTHER FOR ANY CONSEQUENTIAL, INCIDENTAL, OR INDIRECT DAMAGES ARISING FROM OR RELATING TO ANY BREACH OF THIS AGREEMENT, REGARDLESS OF ANY NOTICE OF THE POSSIBILITY OF SUCH DAMAGES. NOTWITHSTANDING THE FOREGOING, NOTHING IN THIS SECTION 13.4 IS INTENDED TO OR SHALL LIMIT OR RESTRICT THE INDEMNIFICATION RIGHTS OR OBLIGATIONS OF ANY PARTY UNDER SECTION 13.1 OR 13.2, OR DAMAGES AVAILABLE FOR A PARTY’S BREACH OF CONFIDENTIALITY OBLIGATIONS UNDER ARTICLE 11.

13.5 Insurance. Each Party shall procure and maintain insurance, including clinical trials insurance and product liability insurance, adequate to cover its obligations hereunder. Certificates of insurance (in English) evidencing such coverage will be made available to the other Party upon written request.

14.1 Term. This Agreement shall come into force on the Effective Date, and shall continue in effect unless earlier terminated in accordance with this ARTICLE 14 (the “Term”).

14.2 Termination. This Agreement shall automatically terminate upon the expiration or termination of the Collaboration Agreement.

14.3 Termination for Breach. If either Party to this Agreement shall have materially breached or defaulted in the performance of any of its obligations under this Agreement and does not remedy the breach within [***] of notice from the other Party to do so (if capable of remedy), the non-breaching Party may terminate this Agreement immediately by notice to the Party in breach.

If this Agreement is terminated by Kaken pursuant to Section 14.3 or if this Agreement automatically terminates pursuant to Section 14.2 on account of termination of the

Collaboration Agreement by Kaken pursuant to Section 11.1 or Section 11.3 of the Collaboration Agreement or on account of termination of the Collaboration Agreement by Brickell in accordance with Section 11.4 of the Collaboration Agreement, then unless otherwise agreed to in writing by the Parties, Brickell shall pay for [***].

15.2 Accrued Rights and Surviving Obligations. Termination or expiration of this Agreement for any reason shall be without prejudice to any rights that shall have accrued to the benefit of any Party prior to such termination or expiration. Such termination or expiration shall not relieve any Party from obligations that are expressly or by implication intended to survive termination or expiration of this Agreement and shall not affect or prejudice any provision of this Agreement that is expressly or by implication provided to come into effect on, or continue in effect after, such termination or expiration.

16.1 Entire Agreement; Amendment. This Agreement, including the Schedules hereto, and the Collaboration Agreement set forth the complete, final and exclusive agreement and all the covenants, promises, agreements, warranties, representations, conditions and understandings between the Parties hereto with respect to the subject matter hereof. 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 or addition to this Agreement shall be binding upon the Parties unless reduced to writing and signed by an authorized representative of each Party.

16.2 Force Majeure. A Party shall be excused from the performance of its obligations under this Agreement to the extent that such performance is prevented by force majeure and the nonperforming Party promptly provides notice of the prevention to the other Party. Such excuse shall be continued so long as the condition constituting force majeure continues and the nonperforming Party makes reasonable efforts to remove the condition. For purposes of this Agreement, force majeure shall include conditions beyond the control of the Parties, including an act of God, war, civil commotion, terrorist act, labor strike or lock-out, epidemic, failure or default of public utilities or common carriers, destruction of production facilities or materials by fire, earthquake, storm or like catastrophe. Notwithstanding the foregoing, a Party shall not be excused from making payments owed hereunder because of force majeure affecting such Party, unless such event of force majeure specifically prevents the prevented Party from making such payments, in which event such prevented Party shall use commercially reasonable efforts to make such payments through alternative means; provided, however, that in any case such payments shall continue to be due and payable hereunder.

16.3 Notices. Any notice required or permitted to be given under this Agreement shall be in writing, shall specifically refer to this Agreement, and shall be addressed to the appropriate Party at the address specified below or such other address as may be specified by such Party in writing in accordance with this Section 16.3, and shall be deemed to have been given for all purposes (i) when delivered, if hand-delivered or sent by facsimile or e-mail on a Business Day, (ii) on the next Business Day if sent by a reputable

international overnight courier service, or (iii) five (5) Business Days after mailing, if mailed by first-class certified or registered airmail, postage prepaid, return receipt requested. Unless otherwise specified in writing, the mailing addresses of the Parties shall be as described below:

16.4 No Strict Construction; Interpretation, No Beneficiaries. This Agreement has been prepared jointly and shall not be strictly construed against either Party. Ambiguities, if any, in this Agreement shall not be construed against any Party, irrespective of which Party may be deemed to have authored the ambiguous provision. The headings of each Article and Section in this Agreement have been inserted for convenience of reference only and are not intended to limit or expand on the meaning of the language contained in the particular Article or Section. There are no third party beneficiaries of this Agreement or any rights hereto.

16.5 Assignment and Delegation. Neither Party may assign or transfer this Agreement or any rights or obligations hereunder without the prior written consent of the other, except that either Party may make such an assignment without the other Party’s consent to a successor to substantially all of the business of a Party to which this Agreement relates, whether in a merger, sale of stock, sale of assets or other transaction, provided that such successor agrees to be bound by the terms of this Agreement. Any assignment or attempted assignment by either Party in violation of the terms of this Section 16.5 shall be null, void and of no legal effect.

16.6 Compliance with Applicable Law; Further Actions. Each Party shall comply with all applicable Law in performing its obligations pursuant to this Agreement. Each Party also agrees to execute, acknowledge and deliver such further instruments, and to perform all such other acts, as may be necessary or appropriate in order to carry out the purposes and intent of this Agreement.

16.7 Severability. If any one or more of the provisions of this Agreement are held to be invalid or unenforceable by any court of competent jurisdiction from which no appeal can be or is taken, such provision or provisions shall be considered severed from this Agreement and shall not serve to invalidate any remaining provisions hereof. The Parties shall make a good-faith effort to replace any invalid or unenforceable provision with a valid and enforceable one such that the objectives contemplated by the Parties when entering this Agreement may be realized.

16.8 No Waiver. Any delay 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, except with respect to an express written and signed waiver relating to a particular matter for a particular period of time.

16.9 Independent Contractors. Each Party shall act solely as an independent contractor, and nothing in this Agreement shall be construed to give either Party the power or authority to act for, bind, or commit the other Party in any way. Nothing herein shall be construed to create the relationship of partners, principal and agent, or joint-venture partners between the Parties.

16.10 English Language; Governing Law. This Agreement was prepared in the English language, which language shall govern the interpretation of, and any dispute regarding, the terms of this Agreement. This Agreement and all disputes arising out of or related to this Agreement or any breach hereof shall be governed by and construed under the laws of the State of New York, without giving effect to any choice of law principles that would require the application of the laws of a different state.

16.11 Counterparts. This Agreement may be executed in two (2) counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument and may be executed by Adobe portable document format or substantially similar technology.
