For each of the United States and China, subject to Section ‎5.2.4(b) (Co-Commercialization Agreement), Denali shall have an option (“Co-Commercialization Option”) to elect to provide between [***] and [***] of the Detailing efforts and MSL Activities for each CNS Product in the relevant country for Indications [***] (such percentage range, the “Denali Activities Range”), such activities, collectively, the “Co‑Commercialization Activities” and either such country, once elected, is part of the “Co‑Commercialization Territory” and is a “Co-Commercialization Country” and for so long as the Parties are engaged in Co-Commercialization Activities with respect to such CNS Product in such Co-Commercialization Country, such CNS Product is a “Co-Commercialization Product”). For purposes of the preceding sentence, any efforts with respect to electronic contacts by means of information technology (e.g., videoconferencing) by or on behalf of either Party shall not be considered in determining the percentage of Detailing efforts and MSL Activities provided by Denali. Denali may exercise the Co-Commercialization Option for each such CNS Product in each such country (on a country-by-country and CNS Product-by-CNS Product basis) by (a) providing written notice to Sanofi no later than [***] before the anticipated Commercial launch of the applicable CNS Product in such country; and (b) reasonably demonstrating to Sanofi that Denali has, or will have on a timely basis, resources in place sufficient to perform Denali’s share of the Co-Commercialization Activities for such CNS Product in such country.

(b) Co-Commercialization Agreement. The first time Denali exercises the Co-Commercialization Option for a CNS Product in a Co-Commercialization Country, the Parties shall negotiate in good faith terms and conditions of a co-commercialization agreement pursuant to which they will conduct the Co-Commercialization Activities for such CNS Product in the applicable country (“Co-Commercialization Agreement”) and, to the extent Denali exercises its Co‑Commercialization Option for any other CNS Product in such Co-Commercialization Country, the applicable Co-Commercialization Agreement shall be updated to include such CNS Product. The Co-Commercialization Agreement will contain the terms and conditions set forth on Schedule 5.2.4 and such other terms as are agreed upon by the Parties; provided that in the event of any conflict between the terms of a Co-Commercialization Agreement and the terms of this Agreement (including Schedule 5.2.4), the terms of this Agreement shall control. The Parties shall use Commercially Reasonable Efforts to enter into the Co-Commercialization Agreement no later than [***] following the date upon which Denali exercises the Co‑Commercialization Option, or

Until the Parties enter into the Co-Commercialization Agreement, the terms of this Agreement, including those set forth in Schedule 5.2.4, shall govern the Parties’ Co-Commercialization Activities (during such period, references in Schedule 5.2.4 to the Co-Commercialization Agreement shall be deemed to be references to Schedule 5.2.4) and, for the avoidance of doubt, Denali shall have the right to conduct Co-Commercialization Activities in accordance with the terms of this Agreement.

(c) Termination of Co-Commercialization Activities Following Exercise of Denali Royalty Option. If Denali exercises the Denali Royalty Option for a Cost Profit Sharing Product in a Cost Profit Sharing Country, then Denali’s right and responsibility to conduct its portion of the Co-Commercialization Activities in such country for the applicable Cost Profit Sharing Opt Out Product will terminate over a reasonable transition time as specified in this Section 5.2.4(c); provided, however, that (i) unless Sanofi notifies Denali otherwise, Denali’s Co-Commercialization Activities would not terminate if Denali exercises the Denali Royalty Option with respect to a particular Cost Profit Sharing Product in a Cost Profit Sharing Country at a time between [***] before the anticipated date of the launch (as determined by JCC and for which Denali has received written notice) of the relevant Cost Profit Sharing Product in such Cost Profit Sharing Country and [***] following such launch (such time period, the “Launch Window”); and (ii) with respect to any time period outside of the Launch Window, [***] shall be a presumptively reasonable transition period, subject to the Parties’ reasonable determination and agreement otherwise. Notwithstanding the foregoing, in no event shall Denali be responsible for any Allowable Expenses with respect to a Cost Profit Sharing Opt Out Product in a Cost Profit Sharing Opt Out Country after the Co‑Funding End Date for such Cost Profit Sharing Opt Out Product pursuant to Section 7.8.1 (Exercise by Denali) and, to the extent that the JCC requests Denali to continue to conduct any Co-Commercialization Activities after the Co-Funding End Date and during the Launch Window for a particular Product in a particular Cost Profit Sharing Country, Sanofi shall reimburse the FTE Costs and Out-of-Pocket Costs incurred by Denali in the conduct of such Co‑Commercialization Activities that would have been Allowable Expenses had the Co-Funding End Date not occurred.

(d) Termination of Co-Commercialization. At any time after exercising the Co-Commercialization Option for a country, Denali may notify the JCC of Denali’s desire to terminate all of its involvement in the Co-Commercialization Activities for any one or more of the CNS Products in such Co-Commercialization Country. The Parties, through the JCC, will endeavor to make arrangements that transition such activities to Sanofi over a reasonable time determined by the JCC but not to exceed [***] from the date of such notice from Denali unless such notice is delivered during the Launch Window, in which case such [***] period shall begin as of the date of the end of such Launch Window. If Denali exercises the Denali Royalty Option and continues to incur any FTE Costs or Out-of-Pocket Costs pursuant to such a transition of Co-Commercialization Activities following the applicable Co-Funding End Date for the subject Cost Profit Sharing Product, then Sanofi shall reimburse Denali such FTE Costs and Out-of-Pocket Costs. If Denali’s transition after terminating Co-Commercialization Activities for a Cost Profit Sharing Product all occurs during a time while the product remains a Cost Profit Sharing Product, then Denali’s FTE Costs or Out-of-Pocket Expenses shall continue to be allocated towards Allowable Expenses until such transition is complete.

The Parties shall confer with respect to how to respond to such Third Party Claim and how to handle such Third Party Claim in an efficient manner. In the absence of such an agreement, each Party shall have the right to take such action as it deems appropriate.

12.4 Notice of Claim. All indemnification claims in respect of a Party, its Affiliates or their respective directors, officers, employees and agents shall be made solely by such Party to this Agreement (“Indemnified Party”). Subject to Section ‎12.3 (Certain Indemnified Losses), the Indemnified Party shall give the indemnifying Party prompt written notice (“Indemnification Claim Notice”) of any Indemnified Losses or discovery of fact upon which such Indemnified Party intends to base a request for indemnification under this ‎Article 12 (Indemnity; Limitations of Liability; Insurance), but in no event shall the indemnifying Party be liable for any Indemnified Losses to the extent such Indemnified Losses arise from any delay in providing such notice. Each Indemnification Claim Notice must contain a description of the claim and the nature and amount of such Indemnified Loss (to the extent that the nature and amount of such Indemnified Loss is known at such time). The Indemnified Party shall furnish promptly to the indemnifying Party copies of all papers and official documents received in respect of any Indemnified Losses and Third Party Claims.

12.5 Control of Defense.

12.5.1 In General. Subject to the provisions of Section ‎8.4 (Infringement Claims by Third Parties), Section ‎8.5 (Invalidity or Unenforceability Defenses or Actions) and Section ‎8.6.3 (Third Party Claims) and of Section ‎12.3 (Certain Indemnified Losses), at its option, the indemnifying Party may assume the defense of any Third Party Claim by giving written notice to the Indemnified Party within [***] after the indemnifying Party’s receipt of an Indemnification Claim Notice. The assumption of the defense of a Third Party Claim by the indemnifying Party shall not be construed as an acknowledgment that the indemnifying Party is liable to indemnify the Indemnified Party in respect of the Third Party Claim, nor shall it constitute a waiver by the indemnifying Party of any defenses it may assert against the Indemnified Party’s claim for indemnification. Upon assuming the defense of a Third Party Claim pursuant to this Section ‎12.5.1, the indemnifying Party may appoint as lead counsel in the defense of the Third Party Claim any legal counsel selected by the indemnifying Party which

shall be reasonably acceptable to the Indemnified Party. In the event the indemnifying Party assumes the defense of such a Third Party Claim, the Indemnified Party shall immediately deliver to the indemnifying Party all original notices and documents (including court papers) received by the Indemnified Party in connection with such Third Party Claim. Should the indemnifying Party assume the defense of such a Third Party Claim, except as provided in Section ‎12.5.2 (Right to Participate in Defense), the indemnifying Party shall not be liable to the Indemnified Party for any legal expenses subsequently incurred by such Indemnified Party in connection with the analysis, defense or settlement of the Third Party Claim unless specifically requested in writing by the indemnifying Party. In the event that it is ultimately determined that the indemnifying Party is not obligated to indemnify, defend or hold harmless the Indemnified Party from and against such Third Party Claim, the Indemnified Party shall reimburse the indemnifying Party for any Indemnified Losses incurred by the indemnifying Party in its defense of such Third Party Claim.

12.5.2 Right to Participate in Defense. Without limiting Section ‎12.5.1 (In General), any Indemnified Party shall be entitled to participate in, but not control, the defense of such Third Party Claim and to employ counsel of its choice for such purpose; provided that such employment shall be at the Indemnified Party’s own expense unless (a) the employment thereof, and the assumption by the indemnifying Party of such expense, has been specifically authorized by the indemnifying Party in writing; (b) the indemnifying Party has failed to assume the defense and employ counsel in accordance with Section ‎12.5.1 (In General) (in which case the Indemnified Party shall control the defense); or (c) the interests of the Indemnified Party and the indemnifying Party with respect to such Third Party Claim are sufficiently adverse to prohibit the representation by the same counsel of both Parties under Applicable Law, ethical rules or equitable principles.

12.5.3 Settlement. With respect to any Indemnified Losses relating solely to the payment of money damages in connection with a Third Party Claim and that shall not result in the Indemnified Party’s becoming subject to injunctive relief, specific performance or otherwise adversely affect the business of the Indemnified Party in any manner, and as to which the indemnifying Party shall have acknowledged in writing the obligation to indemnify the Indemnified Party hereunder, the indemnifying Party shall have the sole right to consent to the entry of any judgment, enter into any settlement or otherwise dispose of such Indemnified Loss, on such terms as the indemnifying Party, in its sole discretion, shall deem appropriate. With respect to all other Indemnified Losses in connection with Third Party Claims, where the indemnifying Party has assumed the defense of the Third Party Claim in accordance with Section ‎12.5.1 (In General), the indemnifying Party shall have authority to consent to the entry of any judgment, enter into any settlement or otherwise dispose of such Indemnified Loss; provided that it obtains the prior written consent of the Indemnified Party (which consent shall not be unreasonably withheld, delayed or conditioned). If the indemnifying Party does not assume and conduct the defense of a Third Party Claim as provided above, the Indemnified Party may defend against such Third Party Claim. Regardless of whether the indemnifying Party chooses to defend or prosecute any Third Party Claim, no Indemnified Party shall admit any liability with respect to, or settle, compromise or dispose of, any Third Party Claim in a manner that would have a material adverse effect on the Indemnified Party or admit wrongdoing on behalf of the Indemnified Party, without the prior written consent of the indemnifying Party. The indemnifying Party shall not be liable for any settlement, compromise or other disposition of

an Indemnified Loss by an Indemnified Party that is reached without the written consent of the indemnifying Party.

12.5.4 Cooperation. Regardless of whether the indemnifying Party chooses to defend or prosecute any Third Party Claim, the Indemnified Party shall, and shall cause each indemnitee to, cooperate in the defense or prosecution thereof and shall 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 therewith. Such cooperation shall 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 Indemnified Parties 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 shall reimburse the Indemnified Party for all its reasonable out-of-pocket expenses in connection therewith.

12.5.5 Expenses. 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 shall be reimbursed on a Calendar Quarter basis in arrears 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.

12.6 Special, Indirect, and Other Losses. EXCEPT (A) [***], (B) [***], AND (C) [***], NEITHER PARTY NOR ANY OF ITS AFFILIATES SHALL BE LIABLE FOR INDIRECT, INCIDENTAL, SPECIAL, EXEMPLARY, PUNITIVE OR CONSEQUENTIAL DAMAGES, INCLUDING LOSS OF PROFITS OR BUSINESS INTERRUPTION (TO THE EXTENT THE SAME ARE CONSEQUENTIAL DAMAGES), HOWEVER CAUSED AND ON ANY THEORY OF LIABILITY, WHETHER IN CONTRACT, TORT, NEGLIGENCE, BREACH OF STATUTORY DUTY OR OTHERWISE IN CONNECTION WITH, OR ARISING IN ANY WAY OUT OF, THE TERMS OF THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THE USE OF A COMPOUND OR PRODUCT, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGE.

12.7 Insurance. Each Party will procure and maintain liability insurance with carriers rated “A-” AM Best rating or equivalent, including product liability insurance, with minimum limits of [***] per claim and in the aggregate, with respect to its activities hereunder and which are consistent with normal business practices of prudent companies similarly situated at all times during which any Product is being commercially distributed or sold. It is understood that such insurance will not be construed to create a limit of either Party’s liability with respect to its indemnification obligations under this Article 12 (Indemnity; Limitations of Liability; Insurance). Clinical trials insurance must be implemented by the sponsor of the clinical trial in compliance with local Applicable Laws. Each Party will provide the other with written evidence of such insurance upon request. Product liability policies will be maintained for [***] following termination of this Agreement. Notwithstanding the foregoing, (a) Sanofi may self-insure, in whole or in part, the

insurance requirements described above; and (b) Denali may self-insure, in whole or in part, the insurance requirements described [***]).

13.2 Termination for Material Breach. If either Party (“Non-Breaching Party”) believes that the other Party (“Breaching Party”) has materially breached this Agreement, then the Non-Breaching Party may deliver notice of such material breach to the Breaching Party (“Default Notice”). If the Breaching Party does not dispute that it has committed a material breach of this Agreement and the Breaching Party fails to cure such breach within [***] after receipt of the Default Notice, the Non-Breaching Party may terminate this Agreement upon written notice to the Breaching Party; provided that if such material breach is with respect to only a Program (and not with respect to this Agreement in its entirety), such termination shall be limited to such Program.

13.4 Termination for Insolvency. Either Party may terminate this Agreement in its entirety at any time during the Term by giving written notice to the other Party if the other Party files in any court or agency pursuant to any statute or regulation of any state or country a petition in bankruptcy or insolvency or for reorganization or for an arrangement or for the appointment of a receiver or trustee for the other Party or its assets, or if the other Party is served with an involuntary

If so requested by either Party, the Parties will negotiate and enter into a supply agreement on reasonable and customary terms under which Sanofi will supply Denali with such Terminated Denali Products for the Terminated Area, but the execution of such agreement shall not limit or be a condition to Sanofi performing its obligations under this Section 13.8.1(f)(iii)(B).

(h) Cooperation. Without limiting the foregoing, each Party shall use Commercially Reasonable Efforts to cooperate with the other Party to effect a smooth and orderly transition in the Terminated Portions in the Terminated Area in a prompt and expeditious manner in accordance with the terms of this Agreement.

In the event of a breach or threatened breach of any provision of such Section or Articles, the Non-Breaching Party shall be authorized and entitled to seek from any court of competent jurisdiction injunctive relief, whether preliminary or permanent and specific performance. Nothing in this Section ‎15.10 is intended, or should be construed, to limit either Party’s right to equitable relief or any other remedy for a breach of any other provision of this Agreement.

15.11 Waiver and Non-Exclusion of Remedies. Any term or condition of this Agreement may be waived at any time by the Party that is entitled to the benefit thereof, but no such waiver shall be effective, unless set forth in a written instrument duly executed by or on behalf of the Party waiving such term or condition. The waiver by either Party hereto of any right hereunder or of the failure to perform or of a breach by the other Party shall not be deemed a waiver of any other right hereunder or of any other breach or failure by such other Party whether of a similar nature or otherwise. The rights and remedies provided herein are cumulative and do not exclude any other right or remedy provided by Applicable Law or otherwise available except as expressly set forth herein.

15.12 No Benefit to Third Parties. Except as provided in ‎Article 12 (Indemnity; Limitations of Liability; Insurance) and Section 6.5.1 (Existing Denali In-License Agreements), covenants and agreements set forth in this Agreement are for the sole benefit of the Parties hereto,

15.14 Relationship of the Parties. It is expressly agreed that Denali, on the one hand, and Sanofi, on the other hand, shall be independent contractors and that the relationship between the Parties shall not constitute a partnership, joint venture or agency, including for all tax purposes; [***]. Except to the extent expressly stated in this Agreement, neither Denali, on the one hand, nor Sanofi, on the other hand, shall have the authority to make any statements, representations or commitments of any kind, or to take any action, which shall be binding on the other, without the prior written consent of the other Party to do so. All persons employed by a Party shall be employees of such Party and not of the other Party and all costs and obligations incurred by reason of any such employment shall be for the account and expense of such Party.

This Agreement may be executed in two (2) or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one (1) and the same instrument. This Agreement may be executed by facsimile or electronically transmitted signatures and such signatures shall be deemed to bind each Party hereto as if they were original signatures.

15.17 References. Unless otherwise specified, (a) references in this Agreement to any Article, Section or Schedule shall mean references to such Article, Section or Schedule of this Agreement; (b) references in any Section to any clause are references to such clause of such Section; and (c) references to any agreement, instrument or other document in this Agreement refer to such agreement, instrument or other document as originally executed or, if subsequently amended, replaced or supplemented from time to time, as so amended, replaced, or supplemented and in effect at the relevant time of reference thereto.
